U.N. General Assembly: Obama Calls to "New Era of Engagement"
Barack Obama says the USA can not solve global problems alone. The president is calling for "a new era of engagement" all around the world.
The U.S. leader made the remarks during his maiden address at the annual United Nations General Assembly which opened in New York city on Wednesday.
Mr. Obama vowed to "act boldly" for justice and prosperity at home and abroad. But, he added, all nations must take their share of responsibility for global responses to pressing global problems, including poverty, climate change, the economy and nuclear non-proliferation and disarmament.
President Obama told the leaders of the 192-member states that America is doing its part. He noted U.S. actions to end the war in Iraq, prohibit torture, and provide development aid to countries including Afghanistan and Pakistan, Voice of America reports.
It was also reported, the president devoted a significant proportion of his speech to the challenges of finding a peaceful settlement in the Middle East - and called for the relaunch of "negotiations without preconditions".
He said he did not underestimate the scale of that challenge, but added: "I will not waver in my pursuit of peace."
On Tuesday, at the UN's climate change summit, Mr Obama acknowledged that the US had been slow to act, but promised a "new era" of promoting clean energy and reducing carbon pollution.
Some countries may not take kindly to his words urging greater responsibility if it sounds too much like a lecture, particularly those who feel his commitments to tackle global warning were disappointing, says the BBC's Mark Mardell in New York, BBC News reports

Phenotypic plasticity and speciation in cichlids (PlasticitySpeciation)
Phenotypic plasticity is considered a catalyst for speciation through two alternative mechanisms: the Baldwin effect and genetic assimilation. Midas cichlids – Nicaraguan freshwater fishes where multiple species diverged in sympatry in crater lakes after colonization from larger source lakes – are the ideal model to study the influence of plasticity in speciation. The presence of trade-offs in the morphology of Midas cichlids’ pharyngeal jaw – a trophic structure used to crush hard food items which plastically modifies its size and shape when subjected to hard food – allows to generate specific hypotheses. In fact, according to theoretical models, in presence of trade-offs genetic assimilation is more likely than the Baldwin effect. I will use common garden experiments involving two Midas species from Lake Apoyo and the species from Lake Nicaragua (which acted as a source for Lake Apoyo) subjecting the fish to hard and soft diet treatments, that are nutritionally identically and only differ in their hardness. I will then measure the levels and directions of plastic response in each species/treatment using advanced geometric morphometric analyses and I will assess their transcriptional correlates using a combination of Illumina RNA next generation sequencing and RT-qPCR. I will, therefore, be able to test the following three hypotheses: 1. that the derived populations from Lake Apoyo show lower levels of plasticity than source species (as expected as a consequence of genetic assimilation); 2. that the plastic response in the source population produces the same phenotypes found in natural populations of the derived species (as expected according to the “flexible stem hypothesis”); 3. comparing the results with published data from African cichlids, that the genes differentially expressed in pharyngeal jaw plastic response are the same in both closely and distantly related cichlid lineages (thus suggesting a conserved molecular basis for pharyngeal jaw plasticity).

Discussion on: Could Tesla Succeed In India?
ananddhruv295 profile image
Dhruv Anand
Considering the data that Maruti Suzuki, Hyundai and Tata are successful in India, the reason is quiet simple, these brands provide cars that are not very expensive, and can be afforded by the "normal" people.
Talking about Tesla, there are not high chances that Tesla would be able to achieve such high success compared to these brands.

By integrating the carabiner with the rigging plate, the system is lighter, less cumbersome and more effective. Opening by Twin-Gate wire-gate system, which does not require any additional maneuver (e.g. screwing), making it safer and faster than other systems. Furthermore, it allows to avoid accidental openings that can occur for example due to contact with the rock, due to incorrect passage of the rope due to involuntary hand pressure. Two openings also allow greater resistance than one. Finally, it maintains its functionality over time and does not fear the presence of dust, earth, ice like other systems. The gate-wire combination facilitates its use even with gloves, and allows you to easily attach all types of devices (brakes).

gutter instinct
Few places lay claim to a specific type of sound more than Sweden. Even before becoming known as the birthplace of melodic death metal and the subsequent modern metal movement, the country spawned its own specialized death metal movement characterized by the buzzsaw guitars, thrashing speeds, and grinding chaotic brutality popularized by acts such Dismember and Entombed.
Since its origins as a spin-off of d-beat and hardcore punk, things have come full circle, with bands such as Nails and Trap Them bringing the sound back to hardcore. However, there are bands still actively pursuing the Swedish death metal ideal, and Gutter Instinct are making their name as acolytes of the sound while aggressively exploring further ground, citing influences from acts such as Portal and Bolzer. Catch a stream of the group’s debut track, ‘The Invisible Hand‘ after the jump!
Gutter Instict’s debut EP The Insurrection will be out May 19th through Prosthetic Records. Pre-orders for the limited 12″ vinyl EP can be found at this location.

Manomay Shravage
Of course, if you suddenly stopped the Earth from spinning, most of our planet would rapidly become very inhospitable. Half of the planet would almost continuously face the heat of the Sun, while half would face the cold of space. Life could continue in a narrow twilight zone between the hot and cold halves. But this twilight zone would slowly creep around the planet over the period of a year, as the Earth did its annual orbit around the Sun.To make it easier to work out what would happen, let's pretend the oceans don't freeze on the cold side, or evaporate on the hot side. And let's look only at centrifugal force, which should really be called centripetal force.
But this bulge in the solid Earth took billions of years to slowly develop. This is because the solid matter moved only very slowly in response to the outward force caused by the spin of the planet.But the liquid water in the oceans is far more mobile and responsive to forces. So the Earth's spin has pushed up this liquid water to an 'abnormal' elevation of about eight kilometres. In other words, at the equator, thanks to the spinning Earth, the water has been pushed up some eight kilometres higher than in the case of the Earth having no spin.
But today, on the entire equator, the deepest part of the oceans is only about 5.75 kilometres. So take away the spin and you take away all water at the equator. If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. At first, only small regions of terra firma around the equator would rise out of the retreating waters.

PLATO Hare-and-Hounds exercise: Modelling main sequence stars
Cunha, Margarida S. et al.
In the context of the preparation for the PLATO mission, it is vital to understand the accuracy expected on asteroseismically-inferred stellar properties. To that end, we performed a hare-and-hounds exercise where the hares simulated data for 6 artificial stars and the hounds inferred their properties based on the data provided and different inference procedures. To mimic a typical pipeline, such as that planed for the PLATO mission, all hounds used the same model grid. Some stars were simulated using the same physics set up as the model grid, others a different one. In this presentation we will show that generally the accuracy on the inferred properties is better than the PLATO requirements. Moreover, we will highlight the impact on the accuracy of the inferred stellar properties from changing different aspects of the physics adopted for the targets, as well as from changing the uncertainties in the classical observations considered in the fit. Interestingly, the results indicate that only a few mode frequencies are required to achieve accurate results on the mass and radius. The same is true for the age, if at least one l=2 mode is detected.

Wintersmiths Ice Baller
For a while now we’ve loved the Neat Ice Kit, which lets you freeze perfectly clear blocks of ice for use in cocktails. We also dig Tovolo’s sphere ice molds, which (as their name suggests) creates perfectly round — but unfortunately cloudy — ice spheres.
The Wintersmiths Ice Baller combines these two concepts into one product, allowing you to freeze clear ice spheres.
Comprised of a silicon mold, an insulating outer mold, and a stainless steel tumbler, the Ice Baller uses the same “directional freezing” method as the Neat Ice Kit, pushing impurities and air bubbles downward and leaving the water in the upper spherical mold totally clear by the time it freezes. Let it freeze overnight, rinse the mold with some cool water to loosen its hold a little, then take the ice sphere out and use it in any drink you like.

The cool (heh) thing about these ice spheres is that their surface area-to-volume ratio is lower than a cube’s. This means they melt more slowly, thereby causing less dilution while you enjoy your beverage. Plus they just look awesome.
The Ice Baller kit is $85 at Wintersmiths.

How we change what others think, feel, believe and do
Developing Class Rules
Disciplines > Teaching > Classroom Management > Developing Class Rules
Description | Example | Discussion | See also
Rather than lay down the rules for how students behave in class, engage them in a discussion on what these rules should be. This may sound like a recipe for for some rather lax rules, but you can mitigate this in several ways.
Start with the criteria for rules: that they are there to help everyone learn and work together.
There are two ways you can collect the ideas. In method one, you just write ideas down, whatever they are, then discuss each one afterwards, modifying or crossing out the ideas (or transposing to a new place on the whiteboard or blackboard). This has the advantage of accepting everyone and encouraging new ideas. It may also encourage silly suggestions -- you can write these down or turn them down, although this will create tricky decisions on what, exactly to include.
In the second method, which is generally best if the pupils are likely to engage in silly suggestions, is to only write down completed and agreed suggestions. Note that you have to agree all ideas and so are the final arbiter and censor.
If they are slow starting, get things going with some easily accepted ideas, for example about respect.
A discussion of what 'fair' is may be appropriate at some point, especially if some unfair suggestions are made.
Also include rules for the teacher, such as arriving on time and apologizing, but be careful about setting yourself up for later games ('I'm upset -- you have to apologize -- it's the rules!').
Keep the list reasonably short. If you have a longer list, seek to combine items.
Write up the rules on a large sheet of paper and post it on the wall.
Then when the rules are broken, draw the attention of the miscreant (and the class) to the rule.
'Good morning, class. I think we need to set up rules for behaving in the class. I was going to make a list, but then I thought it would be a good idea if you could make suggestions. Do you think you could do this? What we need is for everyone to be able learn and to get on with one another. What rules would you suggest for behaving to help this?'
Clear rules help create certainty and, when applied consistently and fairly, a sense of control. Making these visible and explicit can contribute strongly to classroom discipline.
Involving students in decisions is a classic way of getting them to buy into change and accept the conclusions. Particularly if you can get the potential offenders involved, then they can be more easily reminded when they break the rules.
Remember that, once the rules are set, you must enforce them. Having engaged the students in their construction, you now have an obligation to them to make them work.

If you have an interest in becoming a speech language pathologist, you likely have some questions and would like answers. A speech-language pathologist is typically found in hospitals or other healthcare facilities as well as schools. Those speech-language pathologists that work in hospitals will assist the physicians or other medical staff in diagnosing and treating various conditions and diseases through speech therapy. To answer your questions about this exciting career, this article offers several tips.
Unlike most doctors, speech-language pathologists typically do not have a doctoral degree in order to practice medicine. Instead, they generally earn a Master’s degree in the field, pursue a doctorate, or even work as an administrative assistant for a hospital.
If you are interested in pursuing this career, the first step is to choose a graduate program with a focus on speech pathology. It is important that your graduate program include courses that are focused on language, pediatrics, physiology and other aspects of speech. There are numerous graduate schools to choose from so make sure to do some research on your prospective graduate program to ensure it will prepare you for your career.
The most common type of speech-language pathologist job that a speech-language pathologist will have is one where he or she is helping to diagnose and treat a child who has a speech disorder such as stuttering, fluency problems, speech disorders such as asthma or allergies or the like. These speech-language pathologic jobs involve working with children and working with their respective families. A speech-language pathologist’s job involves diagnosing the pathology of a child’s speech disorder so that the child can be treated accordingly. In fact, many speech language pathologists also act as speech pathologists or speech-language pathologists in conjunction with otolaryngologists and audiologists, meaning that they diagnose and treat disorders that involve speech as well as voice organs such as the larynx, vocal chords, vocal fold, throat, jaws, tongue, jaw and chin.
The length of a speech-language pathology program ranges from two to three years. Most programs last a year but there are some programs that last a couple of semesters in addition to the year-round program. An associate’s degree is usually required before an individual can enroll into a full bachelor’s degree or doctorate program. Many speech-language Pathologists choose to continue their education by getting their master’s degrees. These professionals complete even more advanced degrees and earn even higher salaries.
The majority of speech-language pathologists work with school teachers or school administrators. They generally are employed in schools in the lower grades, working with students who speak English as a first language. The schools that hire speech language pathologists work to provide children with a second language in order to bridge the communication gap between the classrooms and the students who are unable to grasp the fundamental aspects of spoken and written English. School teachers typically assign speech language pathologists to one of their elementary classes, but the positions can be filled by any teacher who is qualified and willing to accept the challenges and rewards that the job presents.
Requirements to Obtain a Degree
In order to work as a speech language pathologist, a candidate must possess a Master’s degree in speech language pathology from an accredited university or institution. In addition to the Masters degree, it is also necessary for speech-language pathologists to have a minimum of 2 years of experience in providing speech language diagnosis and treatment. In order to qualify, speech-language pathologists must have a teaching record and at least a year of experience in providing speech language diagnosis and treatment in the community. Before entering into a Master’s program, speech-language pathologists must first complete their undergraduate degree, which often requires a large amount of coursework including anatomy, physiology, statistics and other mathematics-related courses.
Students in the speech-language pathology graduate program must have already completed their bachelor’s degree. They must have at least a master’s degree in the area, although some specialize in specific areas of speech-language pathology and require additional graduate-level courses. Some speech-language pathologists work in private practice, while others work in hospitals or clinics as part of an audiologist team. Regardless of where they work, all speech-language pathologists need to have extensive experience in the diagnosis and treatment of the speech disorders they treat.
Before becoming a speech pathologist, you will complete an education and training program that will include classroom and clinical instruction in diagnosing and treating disorders of the speech language. During your education, you will learn how to assess language disorders such as fluency, stammering, stuttering, and lip reading. You will also learn how to administer diagnostic tests like the IELTS and TOEFL.
After completing a speech-language pathology training program, you can practice your skills with patients of all speech status, from fluency to stuttering. This training will prepare you for specialized speech pathology positions in both the private and public sectors.
Speech language pathology (SLP), often referred to as speech pathology, is concerned with diagnosing and treating problems related to speech, language, voice, and swallowing that may arise in children and adults
The American Speech-Language-Hearing Association (ASHA) recommends that prospective speech language pathology students attend schools that are accredited by the CAA.
So the first step in one’s journey to obtain a speech pathologist degree is to complete an accredited graduate program in speech, language pathology, or communication disorders. You will need to complete an entry-level degree in a field accredited by the Council on Academic Accreditation in Audiology and Speech-Language Pathology in order to become a speech-language pathologist.
Program titles may include without limitation: MS Communicative Sciences and Disorders MS speech language pathology MS Communication Sciences and Disorders, specialization in speech-language pathology Many CAA graduate programs offer: Part-time/evening programs Partially or fully online delivery Combined degree programs (bachelors/masters)
Graduate programs in speech-language pathology consist of approximately 48 credits and are located in colleges/departments of education, audiology, healthcare sciences, public health, behavioral and communication sciences, and rehabilitation.
Clinical Practice Requirements Clinical experiences are integral to all CAA-accredited speech-language programs, allowing students to become acquainted with the profession and apply newly acquired knowledge.
Admissions requirements differ from one graduate program to the next, but all of them require incoming students to take foundational undergraduate courses that prepare them for studying speech language pathology at the graduate level.
Before starting your fellowship, you may need to apply for an intern license or limited license through the board of speech-language pathology and audiology in your state.
For state licensure, a speech-language pathology clinical fellowship is needed that gives practical training to the student. Clinical fellowships in speech-language pathology are completed under the guidance and supervision of a licensed speech-language professional.
A number states follow the clinical fellowship requirements that must be met to earn the Certificate of Clinical Competence (CCC-SLP) credential through the American Speech-Language-Hearing Association, which requires a clinical fellowship to: consist of the following:
At least 36 weeks, at 35 hours per week, for a total of 1,260 hours
Must be mentored by an ASHA-certified Speech language pathology professional.
Must have at least 80 percent direct clinical contact, such as through activities related to assessment, diagnosis, evaluation, screening and similar contact.
The Council on Academic Accreditation for Audiology and Speech Language Pathology (CAA) approved online SLP programs are usually the best for certification and licensure.

2.5 Assignment 2
Climate Change
There have been many studies documenting that the average global temperature has been increasing over the last century. The consequences of a continued rise in global temperature will be dire. Rising sea levels and an increased frequency of extreme weather events will affect billions of people.
In this problem, we will attempt to study the relationship between average global temperature and several other factors.
The file climate_change (CSV) contains climate data from May 1983 to December 2008. The available variables include:
• Year: the observation year.
• Month: the observation month.
• Temp: the difference in degrees Celsius between the average global temperature in that period and a reference value. This data comes from the Climatic Research Unit at the University of East Anglia.
• CO2N2O, CH4CFC.11, CFC.12: atmospheric concentrations of carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), trichlorofluoromethane (CCl3F; commonly referred to as CFC-11) and dichlorodifluoromethane (CCl2F2; commonly referred to as CFC-12), respectively. This data comes from the ESRL/NOAA Global Monitoring Division.
• CO2, N2O and CH4 are expressed in ppmv (parts per million by volume -- i.e., 397 ppmv of CO2 means that CO2 constitutes 397 millionths of the total volume of the atmosphere)
• CFC.11 and CFC.12 are expressed in ppbv (parts per billion by volume).
• Aerosols: the mean stratospheric aerosol optical depth at 550 nm. This variable is linked to volcanoes, as volcanic eruptions result in new particles being added to the atmosphere, which affect how much of the sun's energy is reflected back into space. This data is from the Godard Institute for Space Studies at NASA.
• TSI: the total solar irradiance (TSI) in W/m2 (the rate at which the sun's energy is deposited per unit area). Due to sunspots and other solar phenomena, the amount of energy that is given off by the sun varies substantially with time. This data is from the SOLARIS-HEPPA project website.
• MEI: multivariate El Nino Southern Oscillation index (MEI), a measure of the strength of the El Nino/La Nina-Southern Oscillation (a weather effect in the Pacific Ocean that affects global temperatures). This data comes from the ESRL/NOAA Physical Sciences Division.
Problem 1.1 - Creating Our First Model
We are interested in how changes in these variables affect future temperatures, as well as how well these variables explain temperature changes so far. To do this, first read the dataset climate_change.csv into R.
Then, split the data into a training set, consisting of all the observations up to and including 2006, and a testing set consisting of the remaining years (hint: use subset). A training set refers to the data that will be used to build the model (this is the data we give to the lm() function), and a testing set refers to the data we will use to test our predictive ability.
Next, build a linear regression model to predict the dependent variable Temp, using MEI, CO2, CH4, N2O, CFC.11, CFC.12, TSI, and Aerosols as independent variables (Year and Month should NOT be used in the model). Use the training set to build the model.
Enter the model R2 (the "Multiple R-squared" value):
Exercise 1
First, read in the data and split it using the subset command:
climate = read.csv("climate_change.csv")
train = subset(climate, Year <= 2006)
test = subset(climate, Year > 2006)
Then, you can create the model using the command:
climatelm = lm(Temp ~ MEI + CO2 + CH4 + N2O + CFC.11 + CFC.12 + TSI + Aerosols, data=train)
Lastly, look at the model using summary(climatelm). The Multiple R-squared value is 0.7509.
Problem 1.2 - Creating Our First Model
Which variables are significant in the model? We will consider a variable signficant only if the p-value is below 0.05. (Select all that apply.)
Exercise 2
If you look at the model we created in the previous problem using summary(climatelm), all of the variables have at least one star except for CH4 and N2O. So MEI, CO2, CFC.11, CFC.12, TSI, and Aerosols are all significant.
Problem 2.1 - Understanding the Model
Current scientific opinion is that nitrous oxide and CFC-11 are greenhouse gases: gases that are able to trap heat from the sun and contribute to the heating of the Earth. However, the regression coefficients of both the N2O and CFC-11 variables are negative, indicating that increasing atmospheric concentrations of either of these two compounds is associated with lower global temperatures.
Which of the following is the simplest correct explanation for this contradiction?
Exercise 3
The linear correlation of N2O and CFC.11 with other variables in the data set is quite large. The first explanation does not seem correct, as the warming effect of nitrous oxide and CFC-11 are well documented, and our regression analysis is not enough to disprove it. The second explanation is unlikely, as we have estimated eight coefficients and the intercept from 284 observations.
Problem 2.2 - Understanding the Model
Compute the correlations between all the variables in the training set. Which of the following independent variables is N2O highly correlated with (absolute correlation greater than 0.7)? Select all that apply.
Exercise 4
Which of the following independent variables is CFC.11 highly correlated with? Select all that apply.
Exercise 5
You can calculate all correlations at once using cor(train) where train is the name of the training data set.
Problem 3 - Simplifying the Model
Given that the correlations are so high, let us focus on the N2O variable and build a model with only MEI, TSI, Aerosols and N2O as independent variables. Remember to use the training set to build the model.
Enter the coefficient of N2O in this reduced model:
Exercise 6
(How does this compare to the coefficient in the previous model with all of the variables?)
Enter the model R2:
Exercise 7
We can create this simplified model with the command:
LinReg = lm(Temp ~ MEI + N2O + TSI + Aerosols, data=train)
You can get the coefficient for N2O and the model R-squared by typing summary(LinReg).
We have observed that, for this problem, when we remove many variables the sign of N2O flips. The model has not lost a lot of explanatory power (the model R2 is 0.7261 compared to 0.7509 previously) despite removing many variables. As discussed in lecture, this type of behavior is typical when building a model where many of the independent variables are highly correlated with each other. In this particular problem many of the variables (CO2, CH4, N2O, CFC.11 and CFC.12) are highly correlated, since they are all driven by human industrial development.

Explain why you say no. Don’t say: “Because I said so!” They want and deserve an explanation. Explaining to your child why you want them to do something, or why you don’t want them to do something, explains the value of it. Once your child understands your reason, they are more likely to accept it. Don’t give your child reason to regard you as mean, or question your motives and values. By communicating openly with your child, you prepare them to be well-balanced, emotionally intelligent adults.
Make your expectations clear in a kind, non-judgmental manner. Reason with them instead of having angry outbursts. Ask them why they did what they did. Your child may tell you something you didn’t know. Ask whether they know why you said no so that they can learn to reason in a calm manner and in a calm environment. Listen when they speak. Ask questions about why they said what they said. Remember, you are teaching them how to get along with others and how to communicate successfully as adults. Model the behaviours you would like them to display.
Allow your child to make suggestions and to find solutions to their problems. Did you know that we use the frontal lobe of our brain to solve problems and to reason? Children can’t predict the consequences of their behaviour because the frontal lobe of their brain isn’t fully developed before the age of 23. You can help your child to develop their frontal lobe earlier so that they can begin to predict the consequences of their behaviour by forcing them to use it. For example, if your child threatens to hit another child, you can ask: “So, what do you think will happen if you hit him?” This question forces the child to use their frontal lobe, even if the answer isn’t what you want to hear. Teach them to use consequential thinking when making choices and decisions. Ask questions that will force your child to reason, even if they get it wrong. Don’t belittle them if they get it wrong. Instead tell them what may happen and why, so that they understand the possible consequences.

Post-upgrade task for cluster using IBM Spectrum Scale replication
During or after the pureScale instance upgrade from a version prior to V11.5, you are required to manually convert the tiebreaker redundancy group ID from 3 to 4. This task is an online operation.
Before you begin
• Ensure that you have root access before you begin this task.
About this task
In a cluster with IBM® Spectrum Scale replication, the redundancy group IDs 1 and 2 are assigned to represent the two data replicas, and ID 4 is assigned to the tiebreaker. ID 3 is reserved for the third data replica in IBM Spectrum Scale.
The following procedure describes the steps to convert a tiebreaker redundancy group ID from 3 to 4 in a IBM Spectrum Scale replication.
Verify if any tiebreaker disk in the file system is associated with 3 as its redundancy group ID using the following command run under root:
/usr/lpp/mmfs/bin/mmlsdisk <fs-name>
Note: The parameter must be prefixed by a /dev/xxx, the user can issue the command "/usr/lpp/mmfs/bin/mmlsfs all -A" to find <fs-name>
For example: /usr/lpp/mmfs/mmlsdisk /dev/db2fs1
If the redundancy group ID 3 is used for the tiebreaker, run the following command to convert it from 3 to 4:
1. Create a stanza file with content:
2. Apply the redundancy group ID change using the stanza file:
/usr/lpp/mmfs/bin/mmchdisk <fs-name> change -F <stanza file>
3. Rebalance the file system using db2cluster utility:
db2cluster -cfs -rebalance -filesystem <fs-name>
Note: Rebalancing of data can be I/O intensive and the duration depends on the size of data. It is recommended to run them at off-peak usage hours. The prefix `/dev/` must be removed from the parameter.
For example: ./db2cluster -cfs -rebalance -filesystem db2fs1

Where’s Aaron: YEAR 1 - Science - Engage
The class is taking turns hosting ‘Aaron’ the class mascot. It is Little J’s turn so Little J, Nanna, Big Cuz, and Old Dog take Aaron on Country to look for mica rock, and along the way they photograph the expedition. Distracted by the events of the day, Little J loses Aaron and the family enrols the help of Uncle Mick, a Search and Rescue officer, to return him.
Engage - Pose and respond to questions about familiar objects and events
Theme - FAUNA
After viewing Little J & Big Cuz Episode 8 ‘Where’s Aaron?’, engage students with the following activities to support their observations and understanding about Australian animals that are diurnal, crepuscular, and nocturnal.
Ask the class to list the animals that Little J and Big Cuz encountered on their walk on Country, such as a skink, an echidna, an owl, and Old Dog (whom the family took with them).
Have students pose and respond to questions why the skink and the echidna were visible during the day, and the owl was not. Introduce students to the terms ‘nocturnal’ (night) and ‘diurnal’ (day) and classify each animal as such. The echidna is both diurnal and nocturnal. Explain to students that scientists also nominate a third category, the ‘crepuscular’ animals, and these animals are most active at twilight, in both morning and evening. (Crepuscular comes from Old French and it means ‘twilight’ or ‘shadow’.) A kangaroo is a crepuscular animal.
Suggested resources to investigate diurnal, nocturnal and crepuscular’ animals, include
Using a clock face, have students suggest what time/s apply to nocturnal and diurnal foraging by animals. Therefore, students could research the local times of dawn and dusk. Remind students that these times will change depending on the seasons during the year.
Use Geoscience Australia chart covering Australia to find out the times of dawn and dusk for your local area. If remote, use your latitude and longitude to get a table of the sunrise and sunset for the whole year. (enter a date or year at the bottom to get the data) Another suggested resource: Perth Observatory data covering Western Australia.
Provide students with a 24 hour clock template and have each student plot the current sunrise and sunset times. Focus students’ attention on how long they think ‘grey dawn’ and ‘twilight’ zones last. (On average, there are about 80 minutes of grey twilight before the sun breaks the horizon at dawn. At dusk, after the sun sets, there are about 30 minutes of twilight before dark, but this varies by season, weather condition and location). Mark the two twilight zones (pre-dawn and post-sunset) on the clock face.
Around the edge of the clock, invite students to select Australian animals that are nocturnal, diurnal, or crepuscular and place them in the daylight zone, the night zone, and the twilight zones. A variety of animals to sort and include might be: Echidna, skink, owl, quoll, kangaroo, bilby, ghost or fruit bat, tawny frogmouth, wolf spider, wallaby, possum, owl, wedge-tailed eagle, magpie, blue-tongued lizard, red-bellied black snake, bush rat, galah, brolga.
Have students enter images and information about nocturnal, diurnal and crepuscular Australian animals in their science journal. They should also note the times of the day when the animals are active in the environment.
A science journal is a record of a students’ observations, experiences and reflections. Each entry is dated and annotated by the student. Annotations may include written labels, drawings, diagrams, charts, small specimens, photographs, and graphs. Student engagement and learning is evident in the science journal.”

Nurses play a crucial role in monitoringand managing patients who develop transfusion-related iron overload from receivingred blood cell (RBC) transfusions forchronic anemia.1 Iron overload is a “silentkiller” in that it damages organs long beforea patient experiences clinical symptoms.1Understanding iron overload is critical topreventing life-threatening consequences,including end-organ damage, amongpatients most at risk1: those with beta-thalassemia,sickle cell disease (SCD),myelodysplastic syndromes (MDS), andother rare anemias (eg, DiamondBlackfan).
This article addresses the most commondiseases in which iron overload can beproblematic: betathalassemia, SCD, andMDS. Discussed are the cellular and molecularmechanisms of iron metabolism; thepathophysiology of beta-thalassemia, SCD,and MDS; the development of chronictransfusional iron overload; signs and symptomsof the condition; monitoring patients;the role of nurses in iron chelation therapy;medications used to treat iron overload; andimproving patient management, patienteducation, and adherence to therapy.Case histories and resources for healthcareproviders and patients are included.
Iron plays an essential role in physiologic processes such asrespiration and DNA synthesis. The human body has manymechanisms to absorb, transfer, and store iron, but noneto excrete it. When the human body is in normal ironbalance, 1 mg to 2 mg of iron enters and is lost daily, leavingonly trace amounts of circulating iron. Dietary iron isabsorbed and circulates in plasma bound to a globulin,transferrin, where it is utilized in muscle and bone marrow.Most of the iron, however, is incorporated into hemoglobinand mature red cells and stored in the liver, ready to bemobilized for reuse.1,2

Chronic Transfusional Iron Overload
Many patients with beta-thalassemia, SCD, or MDS receiveregular transfusions with RBCs as supportive therapy toimprove their hemoglobin levels.1 Each unit of RBCstransfused contains 200 mg to 250 mg of iron; therefore,a patient who receives two units per month will accumulate5 g to 6 g of iron annually.1 The primary complication thatresults from these frequent blood transfusions is chroniciron overload,3 which can occur after as few as 10 transfusions(ie, 20 units of RBCs).1
Normally, iron ions bound to plasma transferrin circulatewithin the body, accumulating within cells in the form offerritin. Iron overload occurs when transferrin becomessaturated, increasing levels of non–transferrin-bound iron(NTBI). As high levels of toxic NTBI accumulate in theblood, they are absorbed into the surrounding tissues, leadingto increased pools of unbound iron. This excess ironinitially accumulates in the reticuloendothelial system, thenthe liver, heart, pancreas, pituitary gland, and parathyroidglands.1,2
Iron overload has serious clinical sequelae: if left untreated,transfusional hemosiderosis—accumulation of iron in theheart, liver, and endocrine glands—can result in organcompromise and, eventually, death.4 The consequences ofiron deposition vary; the pituitary, thyroidal, gonadal,heart, liver, and pancreas are the most common glands andorgans affected.
Hemoglobin disorders are hereditary and consist primarilyof the thalassemias and SCD. Approximately 7% of theworld’s population are carriers of hemoglobin disorders;300,000 to 500,000 children are born annually worldwidewith the most severe forms of the disease.5 In chronicallytransfused patients with thalassemia and SCD, mortalityis three times greater than in the general population ofthe United States. The most common cause of morbidityis iron overload-induced cardiomyopathy.6
Normal adult hemoglobin is made up of two alpha andtwo beta chains folded onto each other and held togetherby the heme group containing iron. Oxygen binds ontothe iron molecule. Production of normal hemoglobin maybe partly or completely suppressed due to inheritance ofmutations or deletions in the gene responsible for the synthesisof one or more globin chains; beta-thalassemia refersto the affected globin chain.7
Beta-thalassemia is classified into two types, dependingon symptom severity: thalassemia major (also known asCooley’s anemia), which is more severe, and thalassemiaintermedia.7 Inheriting two defective beta-globin genescan result in ineffective erythropoiesis, leading to severe,life-threatening anemia, which usually presents in the firstyear of life and, if not treated, can be fatal during infancyor childhood.3 Primary treatment is transfusions withRBCs,3 which relieve severe anemia, suppress compensatorybone marrow hyperplasia, and prolong life.8
Thalassemia is most prevalent in the Mediterranean basin,the Middle East, Southern and Eastern Asia, the SouthPacific, and South China, where reported carrier rates rangefrom 2% to 25%.5 An estimated 1000 individuals are livingwith thalassemia major in the US.9 Signs and symptoms ofbeta-thalassemia are evident within the first 2 years of lifeand include life-threatening anemia, failure to thrive, andjaundice.7
Sickle Cell Disease
Sickle cell disease is a group of inherited genetic disordersin which hemoglobin polymerizes when deoxygenated,leading to hemolysis, blood vessel obstruction by sickledRBCs, and tissue hypoxia.10 Two-thirds of patients haveSCD-SS, in which a child inherits a sickle (S) gene fromeach parent.11 Patients with SCD suffer chronic and episodicpain, reduced quality of life, and life-threatening complications,including stroke.10
Sub-Saharan Africa accounts for more than 70% of birthsaffected by SCD.5 Approximately 2000 infants with SCDare identified by neonatal screening programs in the USannually.11 Timely diagnostic testing, parental education,and comprehensive care can markedly reduce morbidityand mortality from SCD in infancy and early childhood.11Increasingly, hospitals are adopting recommendations thatchronic transfusions be instituted for risk of stroke inchildren with SCD, increasing the need for ironchelation.12

Microsoft Access Tips for Casual Users
Provided by Allen Browne, June 2006. Last updated: April 2010.
Why can't I append some records?
When you execute an append query, you may see a dialog giving reasons why some records were not inserted:
Error screenshot
The dialog addresses four problem areas. This article explains each one, and how to solve them.
Type conversion failure
Access is having trouble putting the data into the fields because the field type does not match.
For example, if you have a Number or Date field, and the data you are importing contains:
In practice, Access has problems with any data that is is not in pure format. If the numbers have a Dollar sign at the front or contain commas or spaces between the thousands, the import can fail. Similarly, dates that are not in the standard US format are likely to fail.
Sometimes you can work around these issues by importing the data into a table that has all Text type fields, and then typecasting the fields, using Val(), CVDate(), or reconstructing the dates with Left(), Mid(), Right(), and DateSerial(). For more on typecasting, see Calculated fields misinterpreted.
Key violations
The primary key must have a unique value. If you try to import a record where the primary key value is 9, and you already have a record where the primary key is 9, the import fails due to a violation of the primary key.
You can also violate a foreign key. For example, if you have a field that indicates which category a record belongs to, you will have created a table of categories, and established a relationship so only valid categories are allowed in this field. If the record you are importing has an invalid category, you have a violation of the foreign key.
You may have other unique indexes in your table as well. For example, an enrolment table might have a StudentID field (who is enrolled) and a ClassID field (what class they enrolled in), and you might create a unique index on the combination of StudentID + ClassID so you cannot have the same student enrolled twice in the one class. Now if the data you are importing has an existing combination of Student and Class, the import will fail with a violation of this unique index.
Lock violations
Lock violations occur when the data you are trying to import is already in use.
To solve this issue, make sure no other users have this database open, and close all other tables, queries, forms, and reports.
If the problem persists, Make sure you have set Default Record Locking to "No Locks" under File (Office Button) | Options | Advanced (Access 2007 or later), or in earlier versions: Tools | Options | Advanced.
Validation rule violations
There are several places to look to solve for this one:
If none of these apply, double-check the key violations above.
Still stuck?
If the problem data is not obvious, you might consider clicking Yes in the dialog shown at the beginning of this article. Access will create a table named Paste Errors or Import Errors or similar. Examining the specific records that failed should help to identify what went wrong.
After fixing the problems, you can then import the failed records, or restore a backup of the database and run the complete import again.

Boyle-Mariotte Law
From wwwelab
Revision as of 22:11, 18 October 2013 by Ist128595 (talk | contribs)
Jump to navigation Jump to search
Experiment Description
The purpose of this experiment is to verify the relation \( p \propto \frac{1}{V} \) (i.e., pressure and volume are inversely proportional) of a gas during isothermal expansion or compression.
• Video: rtsp://
• Laboratory: Basic in[1]
• Control room: pv
• Grade: **
<swf height="270" width="510"></swf>
Experimental Apparatus
The apparatus is composed by a cylinder (5 ml syringe) filled with air, whose plunger is displaced by a servo motor.
Experimental setup
It is possible to choose the compression/expansion limits of the chamber and measure the air pressure and volume inside it during the plunger's motion. The speed at which the transformation occurs can also be specified by choosing the time between samples.
The user must specify the initial and final volume, the number of samples and time interval between them. This last option indirectly defines the speed at which the transformation occurs.
If the experiment is executed with a long time interval between samples, the transformation is close to isothermal. That means the air temperature inside the syringe doesn't change and the Boyle-Mariotte Law is applicable.
The example bellow is one such case where we can verify that the product \( pV \) is, in average, \( 49,3 \pm 0,3 l.kPa \), close to the theoretical value of \( nRT \) (where \( n = 2 \times 10 ^{-4} mol\), equivalent to the full syringe volume at rest \( 5 ml \), PTN).
Graphical fit with experimental results with 1 sec. between samples.
If the time between samples is decreased (i.e. the process is faster), the transformation is no longer isothermal and becomes slightly adiabatic, because there is not enough time for the heat exchange between the inside of the cylinder and the environment. This way, the compression no longer follows the Boyle-Mariotte Law, a fact that is clearly demonstrated by the deviation from the power function, which would be \( ^3/_5 \) in the ideal case (\( \gamma ^{-1} = \frac{c_v}{c_p} \)).
It is difficult to obtain a fast enough compression to achieve this value, since thermalization occurs quickly (in the order of the sound speed). However this can be used to study how the transformation speed influences the deviation between the experimental data and the Boyle-Mariotte Law.
Advanced Protocol
With a high enough time between samples, it is also possible to determine the Ideal Gas Constant, if we consider room temperature to be 22ºC.
1. Run the experiment with about 20 acquisitions, maximum extension between initial and final volume and maximum acquisition time allowed (we are trying to achieve an isothermal transformation).
2. Fit the experimental data to a \( a x ^b \) type function and find the proportion constant (which will equal \( nRT \)).
3. Assume the room temperature to be 22ºC. Determine the amount of substance (in mole) present at the inicial stage of the experiment ( \( 5 ml \) of air at NTP conditions). Find R.
4. Compare the R value that was found through this method with the one found through the average product of \( pV \) (using a math software, determine the product between p and V for each line and then find the average).
5. Find one last estimate for R setting the exponent at -1 (i.e., fitting the data to a \( a x ^{-1} \) function).

Maximum wind speed data from aircraft reconnaissance mission SFMR and dropsonde observations during Hurricane Harvey.
In 2012, we conducted a survey of the 13 facilities participating in the SFMR at that time to examine processes of care, including staffing, diagnostic appointment availability, tracking, communication practices with women and referring providers, and demographics of the population served not otherwise available in the SFMR (e.g., limited English proficiency [LEP]).
Using the SFMR database for all women with any type of mammogram during the study period, we measured the distribution of race/ethnicity (African American, Asian, Latino, White) and educational attainment (<high school graduate, high school graduate/GED, some college, [greater than or equal to]college) for the population served by that facility.
If we compare the Heston model [25], one of representative stochastic volatility models, with the SFMR model, we can get some strengths.
During the 2005 season, only a few aircraft had the instrument available, but now each of the 53rd Weather Reconnaissance Squadron airplanes have the SFMR, nicknamed "the Smurf." This constant measurement of surface winds gives the NHC a considerably more complete picture of the storm and can also determine rainfall rates within a storm system.

The measurement geometry of the downward-pointing, conically-scanning IWRAP Doppler radar and nadir-viewing SFMR instruments on the NOA A WP-3D aircraft.
This multifrequency channel combination principle also led to the development of the SFMR instrument (Harrington 1980), which measures the brightness temperature of the ocean surface using six distinct close-by C-band frequencies, which permit the simultaneous retrieval of both rain rate and surface wind speed.
The primary instruments on the WP-3D include the airborne tail Doppler radar, an X-band radar that provides reflectivity and radial (relative to the radar location) wind components in the presence of scatterers, a C-band radar mounted on the lower fuselage that provides reflectivity, dropsondes, flight-level instruments that measure standard atmospheric parameters, and the SFMR. Though no airborne expendable bathythermographs were deployed, ocean conditions were measured by several Argo profiling floats (e.g., Roemmich et al.
During the IFEX flights, the WP-3D aircraft also featured a C-band lower-fuselage radar that provided reflectivity, flight-level instruments, and the SFMR.
These are computed from the difference in flight level (measured by WC-130J aircraft systems) and surface winds (measured by SFMR) near the time of maximum storm strength (Fig.

Does virtual reality (VR) represent a useful platform for teaching real-world motor skills? In domains such as sport and dance, this question has not yet been fully explored. The aim of this study was to determine the effects of two variations of real-time VR feedback on the learning of a complex dance movement. Novice participants (n = 30) attempted to learn the action by both observing a video of an expert's movement demonstration and physically practicing under one of three conditions. These conditions were: full feedback (FULL-FB), which presented learners with real-time VR feedback on the difference between 12 of their joint center locations and the expert's movement during learning; reduced feedback (REDUCED-FB), which provided feedback on only four distal joint center locations (end-effectors); and no feedback (NO-FB), which presented no real-time VR feedback during learning. Participants' kinematic data were gathered before, immediately after, and 24 hr after a motor learning session. Movement error was calculated as the difference in the range of movement at specific joints between each learner's movement and the expert's demonstrated movement. Principal component analysis was also used to examine dimensional change across time. The results showed that the REDUCED-FB condition provided an advantage in motor learning over the other conditions: it achieved a significantly greater reduction in error across five separate error measures. These findings indicate that VR can be used to provide a useful platform for teaching real-world motor skills, and that this may be achieved by its ability to direct the learner's attention to the key anatomical features of a to-be-learned action.

What is a Connection?
Connection is the way to authorize zenphi to interact with the specified system on your behalf. If your process needs to interact with another system, like Google Sheets, Google Docs, Slack etc. zenphi would need to use a connection to interact with those systems on your behalf. Say you want to update a Google Sheet as part of your process, you first need to create a Google Sheet connection. This connection grants zenphi access to the Google Sheet file, on your behalf.
zenphi Connections
Usually, each connection is specific to an action type. For example, if you create a connection for the Add Row to Google Sheet, you cannot use it to add a row to Salesforce. However, it can be reused for any other Google Sheet Add Row action in the same Flow or other Flows in your workspace. If an existing connection shows up in the Connection control in the action config panel, it means you can select and reuse it.
zenphi Connections
There are two ways to create a new Connection:
• Form the action's config panel
This is the best way to create a new connection because the control automatically select the required connection type for you to create
zenphi Connections
• Form the Connection Page
You can also create a new connection by navigating to the Connection page and click on the New Connection button and then selecting a connection type you would like to create.
zenphi Connections
Connections can be reused by similar actions in in the same Flow and also in the other Flows in your workspace.

Variations in ocean tides essay
The beginning of Luke you are probably really familiar with. Do you know what story is in the beginning?
Variations in ocean tides essay
Values not in the table can be calculated by using linear interpolation.
The History of Weather and Astrology Kim Farnell Astrologer-Writer
Slum is stellar luminosity, it is the Lum column on the table. BC is bolometric correction, it is the Bolo. Steff is effective temperature, it is the Teeff column on the table. These will be used in the equations below. This is important, since generally the only way a planet has oxygen in its atmosphere is by the action of native plant life.
This means that the primary star needs a lifetime longer than 3. This disqualifies stars with a spectral class of higher than F2. Obviously even though K0 stars has a lifespan of 1.
It is of type F7, which means it is hotter and whiter than Sol. Its mass is 1: The diameter is little greater, but spots, prominences, corona, and output of charged particles solar wind are fewer. It is a younger star than ours, though by less than a billion years. Either because of this, or because of variations in galactic distribution, the proportion of heavy elements in it and its planets is somewhat more than for the Solar System.
In earlier days, science fiction customarily put planets around the familiar ones like Sirius, Vega, Antares, or Mira. It was then legitimate enough, if a trifle repetitious. But today we know, or believe we know, that few of the naked-eye stars will serve.
Mostly they are giants, visible to us only because they are so brilliant that we can pick them out across immense gulfs of space. Sol would no longer be discernible without instruments at a distance of about 55 light-years.
Now the red giants like Antares, the variables like Mira, are dying stars, well on their way to the dim, ultra-dense white-dwarf condition.
If ever they had planets—their mass makes that unlikely, as we will see in a minute—the inner attendants have been seared or even consumed, as these suns expanded. Probably the majority of stars in the universe are still enjoying health.
Their temperatures and luminosities vary enormously. The most important reason for this is the difference in their masses. The more massive a sun is, the more intensely compressed it becomes at its core, and thus the more fierce and rapid are the thermonuclear reactions which cause it to shine.
This dependence of output on mass is a highly sensitive one, so that the latter covers a much smaller range than the former. These stars form a well-defined series, from the largest and brightest to the smallest and dimmest, which is called the main sequence. That last, G0, was formerly the classification of our own sun; but more recent information has gotten Sol to be labeled G2.
Figure 1 shows a large part of the main sequence. It omits the extremes, because they really are too extreme to diagram very well. That is, the main sequence runs from the hottest Type O blue giants, some as much as a million times the strength of Sol, on through the yellowish F and G stars, to the red dwarfs of Class M, the dimmest of which may be less than a thousandth as intense as our daystar.
Types are indicated along the bottom of the graph, with corresponding masses. Luminosities—necessarily on a logarithmic scale—are shown going up the left-hand side. From this, you can find the mass corresponding to a given brightness.
They vary by a fair amount, depending on such factors as the age and exact chemical composition of the individual star. More is involved than just the total radiation.
As everyone knows who has ever heated a piece of metal in a fire, temperature affects color. The hottest stars are called blue giants because they are not only giants in output, but also their light contains a distinctly larger proportion of blue than does that of Sol. They also emit a higher percentage, as Well as absolute amount, of ultraviolet and X-ray wavelengths; and no doubt the solar winds streaming from them are something terrific.
All these quantities drop off as temperature does, until we get to the cool, ultraviolet-poor red dwarfs. However, the weaker ones among these last are not mere embers. Sometimes they spit out monstrous flares which may temporarily double the total brightness—a fact which I used in a story once but on which I have no copyright.
Well, shall we put our imaginary world in orbit around one of the spectacular giants? Because they burn at such a prodigal rate, these great stars are short-lived.For the vast majority of science fiction worldbuilding, the major alteration to the laws of physics is allowing some species of faster-than-light propulsion for their starships.
Others will add things like psionics/psychic besides those, the rest of the laws of physics operate exactly as in real life. The ocean tides generated by the gravitational attraction of the sun and moon on the mass of the ocean affect every particle of water from the surface to the bottom of the ocean basin.
Thus, tides have a much greater effect on the ocean phenomena than we are able to observe from our position at its surface. However, tide is a very complex phenomenon. by Nic Lewis We have now updated the LC15 paper with a new paper that has been published in the Journal of Climate "The impact of recent forcing and ocean heat uptake data on estimates of climate sensitivity".

Teams from dozens of countries compete in the UEFA Champions League, and its fan base is much larger.
The Champions League and other UEFA tournaments will be aired across the Middle East and North Africa thanks to a $600 million deal with BeIN Sports.
The three-year deal, which begins in the 2021-2022 season, will keep BeIN as the region’s exclusive rights holder for the Champions League.
The Qatar-based media group is a lesser-known but indisputably prominent sports broadcaster.
1. In December, BeIN signed a $500 million deal to broadcast the Premier League in the MENA region until 2025.
2. In addition to cricket, tennis, rugby, and other sports, the network holds significant rights.
3. Advertisement
4. BeIN had possessed exclusive rights to broadcast La Liga in the United States and Canada, but the league decided to buy those rights back in May. Then ESPN agreed to broadcast La Liga for a projected $1.4 billion through 2029.
The UEFA contract is worth little less each year than BeIN’s previous contract.
Analysts predicted this because the value of rights in the Bundesliga, Serie A, Ligue 1, and other European leagues has lately dropped.

Does Autonomy Really Matter in Language Learning?
Keywords: learner autonomy, language proficiency, academic success/performance, EFL students, foreign language learning
The main aim of this study was to unravel the possible relationship between individuals’ level of autonomy as EFL learners and academic success in terms of language learning at the tertiary level. Additionally, this quantitative study focused on exploring EFL learners’ level of autonomy and also the relationship between learner autonomy and some personal factors, including gender, age, English level, and the length of English education. In order to assess the participants’ levels of autonomy, a questionnaire consisting of 66 items was administered to 267 university students, who were Turkish-speakers of English as a foreign language. The findings showed that more than half of the learners (65.2%) had a high autonomy level with a mean autonomy score of 461.37 out of 660. As for the personal variables, only gender was found to be a significant factor in regards to learners’ autonomy, in this case, in favour of females. Correlation analysis revealed a positive correlation between learner autonomy level and the academic success of language learners. In other words, the academic success of language learners increased with their autonomy and vice versa. In accordance with the literature, the present study revealed that learner autonomy could be considered one of the factors that affects the success of language learners. Based on the findings, it might be suggested that learner autonomy and possible ways to promote it in and out of class should be given more importance. Further empirical research was suggested in order to comprehend unexplored aspects of learner autonomy in language learning.

What is Math Modeling?
An abbreviated description of the process for newbies
Mathematical modeling refers to the process of creating a mathematical representation of a real-world scenario to make a prediction or provide insight. There is a distinction between applying a formula and the actual creation of a mathematical relationship. Some graphical illustrations of the modeling process can be seen on this one page flyer.
Real-world, messy problems can be approached with mathematics, resulting in a range of possible solutions to help guide decision making. Both students and teachers are sometimes uncomfortable with the notion of math modeling because it is so open-ended. So much unknown information seems prohibitive. And what factors are most relevant? But it is this open-ended nature of real-world problems that leads to building and applying problem solving skills, creativity, innovation, and mathematics.
Mathematical modeling can be thought of as an iterative process made up of the following components. (Note that the word “steps” is intentionally avoided to highlight the lack of a prescribed ordering of these components, as some may occur simultaneously and some may be repeated.)
• Identify the Problem Because modeling problems are open-ended, the modeler must be specific in defining what it is they would like to find out.
• Make Assumptions and Identify Variables Since it is impossible to account for all the important factors in a given situation, the modeler must make choices about what to incorporate in their representation of the real-world. Making assumptions helps reveal the variables that will be considered and also reduce the number of them by deciding not to include everything. Within this process, relationships between variables will emerge based on observations, physical laws, or simplifications.
• Do the Math Eventually, a relationship between input and output will allow for a solution to be found.
• Analyze and Assess the Solution When considering the results and insights gained from the model, one asks if the answer makes sense.
• Iterate Usually, the model can be refined and the process can be repeated to improve the model's performance.
• Implement the Model and Report Results A clear report on the model and its implementation makes the model understandable to others.
One of the biggest pitfalls in developing a reasonable model is time management. When modeling is new to students, it is easy for them to get overwhelmed. They may spend too much time “in the weeds.” To define a succinct problem statement, students need to brainstorm and it should be encouraged not to throw out any ideas. However, there are times that students may get caught up in trying to include variables or relationships in their model that are not tractable or where data is just unavailable. At this point, students should make an assumption and move on. They should reflect on those assumptions after a pass through the entire modeling process. Having said that, sometimes students include unneeded assumptions in their documentation that are never explicitly used in the modeling process. This can also take away from valuable time and detract from the presentation of the solution. Students can get off-track while creating models, in particular making choices or assumptions that undermine the solution quality.
When students are in a time crunch, apprehension may lead to mathematical relationships that are removed from reality. It is not uncommon to see nonsense math introduced. For example, students may form an additive relationship between the key variables they identified but the units are meaningless (for example, adding dollars to time to get a model for resources). Coefficients are often used in models that also do not reflect units properly or there is no justification as to why they were chosen. Other times, students may have a sound idea for a mathematical relationship but then overcomplicate it to make the mathematics look more sophisticated (for example, introducing a triple integral when really addition is appropriate). This is another reason why leaving time for reflection is critical, so that a student can read over their entire solution and ask themselves “Does this make sense?”
Dealing with data can also be overwhelming. Students may have a brilliant idea for a model, but cannot find the data they need to move it forward (again, at this point they should make an assumption and stop wasting time looking). Other times, datasets may be prohibitively large and students are not equipped with the tools to interpret key trends. Linear regression or high degree polynomials are often used to fit data without any sound reason and then used as predictors. The connection to the underlying physical problem can get lost or the quality of the fit is ignored completely.
All of the above pitfalls (which is by no means an exhaustive list) can be amended if the team reflects on the quality of their work. If an assumption seemed way off base, students can honestly report out the identified weaknesses of their approach and point the way towards improvements even if they do not have the means or access the information to do so. Even better, a sensitivity analysis can help a student assess the robustness of their model and make comments on its applicability. Much of this circles back to time management.
With more experience modeling, students will naturally gain skills and confidence that can alleviate these issues.

Quick Answer: How do you read the Czech Republic clock?
Does the Prague clock work?
The last renovation of the astronomical clock was carried out from January to September 2018, following a reconstruction of the Old Town Tower. During the renovation, an electric clock mechanism that was in operation since 1948 was replaced by an original mechanism from the 1860s.
How is Prague pronounced?
Czech Pra·ha [prah-hah].
Can you buy an astronomical clock?
Buy a Hermle astrolabium clock for those in your life who admire the beauty of astronomical clocks, but do not have the time or patience to maintain a mechanical clock. Other than replacing the batteries every few years, these clocks are virtually maintenance-free.
How do you read European clocks?
When speaking, however, Europeans might use either the 24-hour-clock number, or a 12-hour-clock number followed by the phrase (in local lingo) “in the afternoon”—so at 3pm, they may say “it’s fifteen o’clock” (or, more usually, just “it’s fifteen”) or they might say “it’s three in the afternoon.”
Which is the biggest clock of the world sun or moon?
Answer: The sun is the biggest clock of the world.
What is astronomic time?
: time reckoned in mean solar time units continuously through the 24 hours beginning either at noon or since 1925 at midnight of each civil day — compare greenwich mean time.

American physiologist

November 4, 1955 (age 66) New York City New York
Awards And Honors:
Nobel Prize (2021)
David Julius, (born November 4, 1955, Brighton Beach, Brooklyn, New York, U.S.), American physiologist known for his discovery of heat- and cold-sensing receptors in the nerve endings of the skin. His elucidation of a receptor known as TRPV1, along with his subsequent contributions to the discovery of additional temperature-sensitive receptor molecules, gave new insight into how the human nervous system senses heat, cold, and pain. His studies of TRPV1 further facilitated research into novel strategies for the treatment of pain. For his breakthroughs, he was awarded the 2021 Nobel Prize in Physiology or Medicine, which he shared with Lebanese-born American molecular biologist and neuroscientist Ardem Patapoutian.
Julius studied life sciences at the Massachusetts Institute of Technology, whence he graduated with a B.S. degree in 1977. He subsequently attended the University of California, Berkeley, where he investigated mechanisms underlying the processing and secretion of peptides in yeast. In 1984, after earning a Ph.D. in biochemistry, Julius went to Columbia University. There, working as a postdoctoral researcher, he applied gene cloning technologies and identified genes belonging to the serotonin receptor family. In 1989 Julius left Columbia to join the faculty at the University of California, San Francisco (UCSF).
At UCSF Julius became interested in ion channels and understanding molecular mechanisms underlying somatosensation, particularly the sensation of pain. At the time, capsaicin, the pungent principle responsible for the burning sensation associated with red peppers (Capsicum), had been recently identified as an excitatory, or activating, compound at certain somatosensory neurons. However, the specific receptor to which capsaicin bound to produce the burning sensation was unknown. Using gene cloning strategies, Julius was able to uncover a receptor in the skin that responded to heat. He subsequently isolated the molecule and identified it as an ion channel, which he called TRPV1 (transient receptor potential cation channel subfamily V member 1).
Julius later contributed to the discovery of other temperature-sensitive ion channels, which became known as the transient receptor potential, or TRP, channel family. Included in the TRP channel family was the first cold-sensing receptor to be discovered, TRPM8 (transient receptor potential cation channel subfamily M member 8), which Julius helped characterize. Together with Chinese-born biophysicist and structural biologist Yifan Cheng, Julius also deduced the structures of TRP channels, notably TRPV1 and TRPA1 (the latter sometimes also called the wasabi receptor) in near-atomic detail by using cryogenic electron microscopy. The discovery and characterization of TRP channels enabled new understanding of how temperature triggers electrical signaling and sensation in the nervous system.
In addition to receiving the Nobel Prize, Julius received the Shaw Prize in Life Science and Medicine (2010), the Canada Gairdner International Award (2017), the Kavli Prize in Neuroscience (2020; shared with Patapoutian), and the Breakthrough Prize in Life Sciences (2020). He was a member of the U.S. National Academy of Sciences (elected 2004) and a trustee of the Howard Hughes Medical Institute (elected 2021).

The Positivity Ripple
How do you show up in the world? When others meet you for the first time, what energy do you radiate? How do others respond to you? Are they drawn to you? These questions may seem strange, but they can shed light on your mindset and give you a better understanding of your actions.
Have you ever been around someone that has a cool vibe? Let’s call her Jane. Jane is happy. She’s a glass half full gal, radiating positivity. Others are drawn to her. She has a unique sense of style and is not overly concerned about what others think of her. Jane projects confidence, but is not cocky. You want to be around Jane. She makes you feel good. Her positive energy is contagious.
Now imagine a very different type of person. Let’s call her Cathy. Drama follows her wherever she goes. It’s like a cloud. There’s always a problem. She views the world negatively. We’re all doomed. Others are out to get me. Cathy attracts similar minded people into her sphere of influence, the Negative Naysayers. After all, misery loves company. If you’re like Jane, this type of person can suck the life out of you.
So, let me ask you again…how do you show up in the world? You may feel that on somedays you have a little Jane in you. On other days you may be more like Cathy. That’s normal. We all have good and bad days. My point, is to make you aware of how your energy is influencing your mindset and your actions.
You may have heard of the Law of Attraction. By definition, the Law of Attraction is a pseudoscience based on the belief that positive or negative thoughts bring positive or negative experiences into a person’s life. The belief is based on the principle that people and their thoughts are made of “pure energy.” Through a process of like energy attracting like energy, a person can influence their life by their thoughts, what they say, and their actions. For example, if a person is positive, looks at challenges as learning experiences, and believes they can have great health, wealth, and positive relationships, they will attract the things they desire. Techniques such as positive affirmations and “I AM” statements help frame the mindset to attract their desires.
In Hinduism and Buddhism, the concept of the Law of Attraction is expressed by karma. Karma is the sum of a person’s actions in this and previous states of existence, viewed as deciding their fate in future existences. You’ve heard the phrase, what goes around comes around. If you’re negative and treat people poorly, others will reciprocate this same behavior towards you.
For many, there is the belief in destiny or fate. Ultimately, our destiny or fate is predetermined. Our actions lead us to that fate.
In terms of behavioral science, what we think about impacts our belief system which drives our behavior. For example, if we tell ourselves repeatedly that we can never be truly happy or successful, these thoughts will become our belief system. This belief system will subconsciously sabotage our behavior, so happiness and success elude us.
Now that you are aware there are forces that impact our beliefs and behavior, how do you choose to show up in the world? Will you be a Jane or a Cathy? Are you happy with the direction your life is taking? Are you surrounded by Jane’s or Cathy’s? If you aspire to be a part of a positivity ripple that will impact your life and the lives of others, I invite you to join my “Be Your Best Self” private Facebook group. It’s a safe space for sharing all things positive. No selling of any kind. Only positivity and encouragement. Members can invite others to join the group. We’re over 1,000 members and growing. If you’d like to be included, please reach out to me. Let’s grow this positivity ripple!

Asteroid that killed the dinosaurs gave birth to the Amazon rainforest
Earth 1 April 2021
New Scientist Default Image
The asteroid that may have killed off the dinosaurs made way for lush South American rainforests
Science Photo Library
Today’s tropical rainforests came about because of the huge asteroid strike thought to have wiped out the dinosaurs.
Before the asteroid hit the Yucatán peninsula in what is now Mexico, South America’s rainforests were made up of vastly different greenery than the abundance of flowering plants they now contain.
“If you returned to the day before the meteorite fall, the forest would have an open canopy with a lot of ferns, many conifers and dinosaurs,” says Carlos Jaramillo at the Smithsonian Tropical Research Institute in Panama. “The forest we have today is the product of one event 66 million years ago.”
Jaramillo and his colleagues analysed tens of thousands of samples of fossilised pollen and leaves found in northern South America that dated to the part of the Cretaceous period just before the asteroid hit, and just after the impact, in the Palaeocene epoch.
They found that plant diversity declined by 45 per cent after the impact and took 6 million years to recover. Insect bites on fossilised leaves showed that insect diversity also took a nosedive.
The rainforests of South America changed in the aftermath of the catastrophe. Most of the cone-bearing plants and ferns disappeared, and the rainforests became dominated by flowering plants called angiosperms. A thick canopy allowed only a little light to reach the ground.
“I think the number one lesson here is unpredictability,” says Ellen Currano at the University of Wyoming. “When you have these major perturbations, they change the rules of the whole ecosystem.”
Jaramillo and his colleagues suggest there are several reasons why the asteroid may have caused this major change. For one, the impact probably killed most of the large, herbivorous dinosaurs that once trampled down and ate the lower levels of the forests.
Plus, the ash that settled out of the sky after the impact may have served as fertiliser, creating a nutrient-rich soil that favoured fast-growing angiosperms over other plants. Angiosperms also appear to have been more ecologically diverse before the impact, which would have made it easier for some of them to bounce back afterwards.
“We love the way it ended up, this incredibly diverse, really structurally complex forest, but right now, we are living through a mass extinction caused by humans and, again, whole ecosystems are being set on a different path,” says Bonnie Jacobs at Southern Methodist University in Texas.
“In the case of the rainforest, we might like the final product, but all those animals that were alive in the Cretaceous did not,” she says.
Understanding how this major event shaped the rainforests can help us put into perspective how these biodiversity hotspots are reacting to deforestation today and how long they could take to recover, says Jaramillo.
“At some of the places we studied, I could see right in front of my eyes how this forest that has taken 66 million years to build was gone in a day, and the rate of deforestation is staggering,” he says. “We know from this study that it takes a long time to build these diverse forests back: you can’t chop down the forest and think, ‘Oh, tomorrow I’ll plant more trees.’ ”

Scrapped Declaration Of Independence Passage Denounced Slavery Most everyone knows the Declaration of Independence was written by Thomas Jefferson. But most don't know about a very big edit before the final draft.
Scrapped Declaration Of Independence Passage Denounced Slavery
• Download
• Transcript
History is full of footnotes and missed opportunities. Thomas Jefferson gets the credit for writing the Declaration of Independence, but it wasn't his work alone. He was on a committee of five appointed by the Continental Congress on June 11, 1776. With Jefferson - John Adams, Benjamin Franklin, Roger Sherman and Robert Livingston. Jefferson wrote a rough draft and presented it to the other four. Seventeen days later, they presented their draft to the Continental Congress. There were edits, debates then final approval on, yes, July 4. Most of the changes to the document were cosmetic except one. In the list of grievances against King George III, there was a section denouncing slavery. It was penned by Jefferson, a slave owner, and part of it went like this...
MARTIN: The sentiments did not go over well with the Southern delegates, and some Northern delegates, who were profiting from the slave trade. The paragraph was dropped, and the rest is history.

How to Choose the Right Bulb Shapes and Sizes?
Acknowledging the bulb’s shape, size, and base is important for understanding what style is suitable for what place. Every light bulb features identifying characteristics called light bulb codes and they are represented in the form of numbers, letters, or series of letters.
Numbers are used for indicating the size of the bulb in millimeters or 1/8 of an inch. While the letter or series of letters represent the shape or unique properties of the bulb. Using the codes, you can easily identify whether the bulb is suitable for your fixture or not.
In this article, we will take a close look at these codes and discuss the various properties of a bulb.
What Are the Different Bulb Shapes and Shape Codes?
The different bulb shapes and shape codes are as follow:
• Arbitrary (A) Bulb shape
• Bullet or Blunt Tip (B) Bulb shape
• Bulged Reflector (BR) Bulb shape
• Conical Or Candle (C) Bulb shape
• E – Ellipsoidal bulb shape
• F – Flame style candelabra bulb shape
• Globe (G) Bulb shape
• MB – Halogen Bulb shape
• Multifaceted Reflector (MR) Bulb shape
• Parabolic Aluminized Reflector (PAR) Bulb shape
• P – Pear bulb shape
• Tabular (T) Bulb shape
You can also check the below chart to see more bulb shapes:
bulb shape code
What Is the Right Bulb Shapes and Sizes?
Although there are a variety of bulbs sizes, we have discussed below only the ones that are most commonly used in our household or for outdoor purposes.
1. A Group:
A shaped light bulbs
A group, Arbitrary group, or Standard group bulbs are used universally for home lighting. These classically shaped bulbs are in every household, and probably we have grown up with them.
Such groups are versatile and suitable for a range of applications which include kitchen lights, ceiling lights, closet lights, lamps, vanity lights, bathrooms, etc.
Bulb’s diameter is represented in 1/8 of an inch using numbers in each code. They are the following:
Code NameDiameter In Eighth Scale
A15 bulb15/8 = 1-7/8
A19 bulb:19/8 = 2-3/8
A21 bulb:21/8 = 2-5/8
A25 bulb:25/8 = 3-1/8
For the A group bulbs, E26/E27 medium screw bases are commonly used.
2. B and C Group:
light bulbs types and sizes
Most bulbs in this category are of candle flame shape and they are also known as candle bulbs.
Blunt-Tip (B) bulbs have a bullet shape. While Conical (C) bulbs are very similar to B bulbs, however, they have a more cone-like shape.
Besides, there is another type known as Conical angular (CA) and it also has a cone shape but with a bent tip.
Such bulb types are mostly used in decorative home lighting applications like chandeliers, night lights, holiday light strands, pendant lights, decorative light strands, wall sconces, etc.
Code NameDiameter In Eighth Scale
B10 bulb10/8 = 1-1/4
CA10 bulb10/8 = 1-1/4
C7 bulb7/8 = 7/8
C9 bulb 9/8 = 1-1/8
C15 bulb15/8 = 1-7/8
For the B and C group bulbs, E12 candelabra, E17, and E26/E27 medium screw bases are commonly used.
3. BR Group:
Bulged Reflector Bulbs
Bulged Reflector (BR) bulbs have a coating of reflector material that is used to accumulate and radiate a wide beam of light off from the bulb. This is how traditional BR bulbs used to work.
However, LED BR bulbs do not need any reflector yet they can incorporate clear, frosted, and patterned lenses with a dome shape.
It enables the light to diffuse and gradually fade into areas where light is not reaching. Such bulbs are commonly used in recessed fixtures, can fixtures, track fixtures, and display fixtures.
Code NameDiameter In Eighth Scale
BR20/R20 bulb 20/8 = 2-1/2
BR30 bulb30/8 = 3-3/4
BR40 bulb40/8 = 5
For the BR group bulbs, E26/E27 medium screw bases are commonly used.
4. G Group:
Globe bulbs
Globe (G) bulbs are also commonly used in households. The bulbs have a round shape and come in several sizes.
Such bulbs are suitable for use in large light fixtures such as chandeliers, foyer lights, and ornamental fixtures.
Code NameDiameter In Eighth Scale
G11 bulb11/8 = 1-3/8
G14 bulb14/8 = 1-3/4
G16/G50 bulb16/8 = 2
G60 bulb60 millimeters =2-3/8
G25/G80 bulb80 millimeters = 3-9/64
G30 bulb30/8 = 3-3/4
For the G group bulbs, an E26/E27 medium screw, and E12 candelabra bases are commonly used.
5. PAR Group:
Parabolic Aluminized Reflector bulbs
Traditionally, Parabolic Aluminized Reflector (PAR) incandescent bulbs come with U-shaped reflectors.
It is utilized for maximizing sharpness and navigating light in a narrow sport beam or wide flood-pattern beam via front of the bulb.
Besides, LED PAR bulbs do not incorporate reflectors, yet emit hard-edged lighting. They are smaller in size than BR bulbs and are most commonly used in floodlight fixtures, sport lights, emergency lights.
Moreover, they are also suitable for indoor use in recessed fixtures, can lights, track lights, and display fixtures.
Code NameDiameter In Eighth Scale
PAR16 bulb16/8 = 2
PAR20 bulb20/8 = 2-1/2
PAR30 bulb 30/8 = 3-3/4
PAR36/AR111 bulb36/8 = 4-1/2
PAR38 bulb38/8 = 4-3/4
For the Pr group bulbs, an E26/E27 medium screw and G53 screw pin bases are commonly used.
6. MR Group:
Multifaceted Reflector Bulbs
MR stands for Multifaceted Reflector. These bulbs come with a reflective and faceted interior and are small in size.
MR LED bulbs do not need facets, however, they still often include them.
MR bulbs are suitable for a number of applications which include recessed fixtures, desk lights, track fixtures, and display case fixtures.
MR bulbs are ideal for outdoor use as well due to their low-voltage wiring systems.
Code NameDiameter In Eighth Scale
MR11 bulb11/8 = 1-3/8
MR16 bulb 16/8 = 2
MR bulbs use completely different bases than other bulbs. For these types of bulbs GX5.3 bi-pin and GZ4 bi-pin in low-voltage AC/DC systems, and GU10 bi-pin – in 120-volt systems are used.
7. T Group:
Tabular bulbs
Tabular (T) bulbs are available in different sizes and shapes.
These types of bulbs are suitable for various applications depending on their size. These applications include pendant lights, chandelier fixtures, and garage troffer lights.
Code NameDiameter In Eighth Scale
T7 bulb7/8 = 7/8
T8 bulb8/8 = 1
T10 bulb10/8 = 1-1/4
T14 bulb14/8 = 1-3/4
T group bulbs use many different type of bases which include E26/E27 medium screw, E12 candelabra, E17, BA15D bayonet, G13 bi-pin.
What Is Your Bulb Base?
Currently, bulbs are available with 6 different types of bases. They are the following:
• Screw bases
• Bi-Pin bases
• Specialty bases
• Fluorescent pin bases
• Twist and lock bases
• Compact Fluorescent lamp plug-in Bases
light bulb base
Among these, only Screw and Bi-pin bases are the two main and commonly used ones. Let’s discuss both of these in detail:
1. Screw Bases:
The most common light bulb base is a screw base. Edison base light bulbs are another name for these bulbs.
Two contact wires connect the filament to the base of an incandescent or halogen screw base light bulb, where the electrical voltage is applied. Screw bases come in a variety of sizes, and they’re labeled with a descriptive name and size on the box.
The number in the light bulb base denotes its diameter in mm. For example: if it is written E-5, then the bulb has a diameter of 5 millimeters.
Here are the most common sizes of screw base E5, E10, E11, E12, E14, E17, E26, E27, E39, E40.
2. Bi-Pin Bases
MR16s, Linear fluorescents, plug-in compact fluorescent bulbs, and a few types of HID light bulbs all have pin bases. Pin base bulbs operate on a different concept than screw base bulbs.
Pin base light fixtures have two pins that stick out of the base and link the bulb to the current, however, screw base light bulbs have two contact wires linked to the metal base and link the bulb to the current.
Electrical current can then travel via the pins and into the light bulb, activating the filament and emit light.
1. Does Light Bulb Shape Matter?
Yes, light bulb shape does matter. Hence, you can look at the above chart to identify all the bulb shapes and be mindful when purchasing a new bulb.
2. What Is the Standard Light Bulb Size?
E26 is the standard size for a light bulb in North America and E27 in Europe.
As you can see there are a variety of bulb shapes and sizes. With this article, we aimed to educate on that.
Not many people are aware that bulbs can be of so many different styles. Hopefully, this article was helpful to you and you get to learn something new from it.

1. In a typical cellular network there are 3 major elements in the cellular infrastructure [note, in some cellular standards these terms are a little bit different, and sometimes two of the three are combined into one. Just answer for the typical cellular terminology – no mention needed of which cellular systems use them]: the basestation (BS), the basestation controller (BSC), and the mobile switching center (MSC). Sometimes the BSC and BS are combined into a Base Transceiver Station or equivalent terminology. Answer the following 2 questions (i and ii), without using graphics, use just words.i)Briefly describe the key functions of the MSC, and WHAT does it connect to?ii)Briefly describe the key functions of the BS, and HOW does it connect to the mobiles?b) Briefly describe the process/technique for decoding an FEC convolutional code, and explain what is meant by saying that the coding gain of a code is 13 dB.c) Imagine a cellular system which uses TDMA (and which is not an existing or past system but it is a possible TDMA system architecture) using a 200 KHz bandwidth carrier, and carrying 8 physical channels in that carrier. i) What defines A CHANNEL, and ii) how much bandwidth does each channel occupy AND why?d) For a QPSK signal received with an SNR (signal to noise ratio) of 13 dB, using 1 MHz bandwidth and carrying 2 Mbps, calculate i) it’s Eb/No, and ii) the BER that is achieved (assume no error correction is being used, so it’s simply the modulation BER performance. Also assume perfect filtering of the QPSK signal).2. Modulation is a function implemented in wireless communications systemsa. Define what is meant by power efficiency and spectral efficiency for a modulation scheme? What is the actual entity measured to specify the two (its physical or mathematical definition), with the units used for the spectral efficiency?b. Order the following modulation types in terms of spectral efficiency (best to worse) and explain why (be specific by showing a number for each representing the spectral efficiency, and how you got it. The correct explanation is what is being asked for here – a simple ordering of best to worse without a correct explanation will get you no points): QPSK, 8-PSK, 64-QAM, and BPSK. You can assume that r=0, ie, perfect filtering.c. Describe the OFDM concept (what is it comprised of and how the signal is generated), explain what is technically important about orthogonality in the OFDM concept, and what makes OFDM better able to work well for higher bandwidths?3. Answer parts a and ba) Select which two statements ARE FALSE. No need to explain here.(1) For antennas used at lower frequencies to have the same gain as those used at higher frequencies, the lower frequency antennas generally have to be bigger.(2) Antennas can have omnidirectional radiation patterns or they can have directional beams in their patterns.(3) In a cellular architecture a forward link is the wireless link from the cell phone to the basestation, and the reverse link is the other way around.(4) ARQ is an error control technique that uses detections of bit errors, and requests retransmissions of frames with erroneous bits.(5) Free space loss is wireless propagation loss in a link where there are free O2 (ie, oxygen) molecules absorbing energy from the propagating signal, and thus further attenuating the signal.WHICH TWO ARE FALSE?b) Select which three (3) statements ARE TRUE. No need to explain here.(1) 3G cellular systems use various forms of spread spectrum modulation and multiple access based on the spread spectrum codes.(2) FEC can correct many erroneously received bits in wireless(3) At cellular frequencies the main source of RF noise in the receiver of a cell phone is a combination of atmospheric noise and other people nearby talking on their desk phones.(4) The Shannon’s capacity formula says that under certain conditions (such as when the noise is white Gaussian) the maximum capacity of a channel is proportional to that channel’s bandwidth.(5) Mechanisms provided by cellular architectures to handle user or cell phone mobility requires having the basestations know when a cell phone is inside its coverage area. This is done by the basestations using GPS to obtain the location of each cell phone.WHICH THREE ARE TRUE?4. On propagation, multipath and other wireless effects and techniquesa) Propagation in a wireless channel is sometimes modeled using the propagation index n. Which of the following three statements is/are TRUE, and which is/are FALSE. NO need to explain here, it is a TRUE or FALSE question for each.i) The propagation index n varies as function of the physical environment for the path, and the frequency. The index n is a function of the matter that make up the path, the objects, gases or liquids in the path, or pure vacuum, and it is then typically higher if there is more solid material (more objects in between), such as buildings, hills or parts of them, vegetation and trees, and other natural and manmade objects.ii) The propagation index depends on the transmit power.iii) The signal will travel further for a propagation index of 4 than for a propagation index of 3, for the same frequency, transmit power levels, and antenna gains.WHICH IS TRUE AND WHICH IS FALSE IN EACH PART OF a)?b)i) describe fast fading in multipath,and ii) describe in detail (ie, not just mention, say what it is and how/why it works) ONE technique to counter it. [Mentioning a number of techniques without explaining how/why one works will get you no points]5. a) Consider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a chipping rate of 2 Mcps (2 million chips per sec). A data source provides a 20 Kbps data rate (20 thousand bits/sec) input into that DSSS system, which spreads the signal and transmits it.i) Calculate the processing gain being used. Show each of your steps;and ii) If you needed to increase the processing gain for the system, while supporting the same source, how would you do it?b) Describe/explain i) what are spread spectrum orthogonal codes, ii) why they are useful, and iii) why sometimes those signals with orthogonal codes transmitted do not stay orthogonal?

graduated cylinder
Follow this link for full answer
Next, what is volume measured in?
Volume is measured in cubic units, while capacity can be measured in almost every other unit, including liters, gallons, pounds, etc.
Beyond that, how do you convert units of liquid volume?
But, how do you measure liquid volume accurately?
Graduated cylinders, beakers, volumetric pipets, burets and volumetric flasks are five kinds of glassware often used to measure out specific volumes. Volumetric pipets, flasks and burets are the most accurate; the glassware makers calibrate these to a high level of accuracy.
How do you measure volume?
Units of Measure
• Volume = length x width x height.
• You only need to know one side to figure out the volume of a cube.
• The units of measure for volume are cubic units.
• Volume is in three-dimensions.
• You can multiply the sides in any order.
• Which side you call length, width, or height doesn't matter.
• 10 Related Questions Answered
What are 3 ways to measure volume?
There are other units for measuring volume; cubic inches, cubic feet, cubic yards are all units used for measuring volume. Milliliters, liters, gallons are also used especially when measuring liquids. We write cubic sizes using a small 3 next to the unit.
Is volume a standard unit?
Volume measures the space inside a 3-dimensional (3D) object. The standard units of volume are cubic metres (m 3), cubic centimetres (cm 3) and cubic millimetres (mm 3). Capacity measures the amount that a 3-dimensional (3D) object can hold. The standard units of capacity are litres (l) and millilitres (ml).
What are 3 common units of volume?
Three common units of volume are:
• cubic centimeters.
• liters.
• gallons.
What are the standard units of liquid volume?
In the metric system of measurement, the most common units of volume are milliliters and liters.
How do you convert liquid volume to weight?
For those people looking for the formula for converting volume to weight, and vice-versa, it looks like this (adapted from answers.com): Density = mass/volume (ρ=m/V). So V=m/ρ and has units (kilograms)/(kilograms per cubic meter)=cubic meter.
What are the customary units of liquid volume?
In the US customary system of measurement, the most common units of volume are cups, pints, quarts and gallons.
How do you find the volume of a liquid calculator?
Our calculator uses the standard formula to determine volume of a rectangular object. This formula is: length x width x height = volume.
Does liquid have a definite volume?
A liquid takes the shape of its container because particles in a liquid can flow to new locations. The volume of a liquid is constant because forces of attraction keep the particles close together. Behavior of Solids: Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
Why are liquids measured in volume?
Liquids are usually measured in volume on a small scale because that is quick, easy and accurate for smaller volumes. Everything that has a physical presence has mass, including liquids and gasses.

Stateful means that a device keeps track of another device or connection for a long period of time, either temporarily or over a long period of time. Stateful connections involve retaining some information about a connection between two systems for future use.
What Is Stateful And Stateless In Networking?
In a stateless protocol, the Client sends a request to the server and the server responds as per that state. In a stateful protocol, if a client sends a request to the server, it expects some kind of response, in case of no response, it resends the request to the server.
What Is Difference Between Stateful And Stateless?
In a stateful service, sessions or transactions are tracked and react in a different way based on the history of the session or transaction. In a stateless service, clients maintain sessions and manage resources instead of the state.
What Is A Stateless Network?
A stateless protocol is a type of network protocol that allows the client to send a request back to the server and server response based on the current state of the network. In this case, the server does not need to retain session information or a status about each communication partner.
What Is The Difference Between Stateful And Stateless Filtering?
A stateful firewall can track and defend against traffic patterns and flows based on its ability to monitor and detect states of all traffic on a network. The only difference between these two is that stateless firewalls filter traffic based on preset rules.
What Is Stateless And Stateful Example?
Due to this, stateful applications can look a lot like stateless ones, and vice versa. In the case of a stateless app, for example, the server can use cookies to track requests originating from the same client, but the app does not require long-term storage.
What Is A Stateful In Networking?
Stateful firewalls monitor the state of all active connections on a network. In other words, stateful firewalls constantly analyze the entire context of traffic and data packets, seeking to access a network rather than isolated traffic and data packets.
Is Http Stateful Or Stateless?
In other words, HTTP is a stateless protocol, so no state information is kept by the server. As opposed to a stateful protocol such as POP3, you must enter a PASS command after entering a USER command.
Is Facebook Stateful Or Stateless?
In Facebook, a stateless service is used to request a list of recent messages from the Facebook API. When the server requests a list of recent messages using the Facebook API, it issues a GET request with a token and date. In this case, the response is independent of the server state, and everything is stored on the client’s machine as a cache.
What Is Called A Stateless Protocol?
As a stateless protocol, HTTP is executed independently, without knowing what requests have already been executed, so once the transaction ends, the connection between the browser and the server is lost as well.
What Is A Stateful Filter?
In firewall technology, stateful inspection, also known as dynamic packet filtering, monitors the state of active connections and determines which packets can be accessed through the firewall based on this information.
What Is The Difference Between Stateful And Stateless Intrusion Detection Scheme?
Information about the server or its sessions is not required to be retained by Stateless Protocol. Status and session information are saved by the server when using Stateful Protocol. The server and client are not tightly connected in Stateless Protocol. Implementing stateful protocols on the Internet is a logical task.
What Does A Stateful Firewall Do?
In a stateful firewall, active network connections are tracked and monitored, while incoming traffic is analyzed and potential traffic and data risks are assessed.
What Is The Stateful And Stateless Acl?
Keeping track of sessions and recognizing flows in a network is a stateful task. In the case of a firewall policy, if a client sends telnet traffic to the server, the policy also recognizes that inbound traffic associated with that session should be allowed. The packet contents are statically evaluated.

Interior Design School of Design Singapore
Shawn Tan
Hey there! Shawn here.
I relish the experiences of trying out different things in life and viewing ideas from different perspectives.
I believe that the beauty of design comes from the potential of it being able to heavily influence the actions and thoughts of individuals and on a larger scale, society.
// 2053: PANDEMIC
// 2053: PANDEMIC
Part 1 of this project speculates a future whereby surveillance and technology have been pushed to the extreme due to the spread of an incurable pandemic, critiquing the underlying repercussions of surveillance and technology in our society through the ways we live.
In the year 2053, an unknown virus has spread throughout the world. In a desperate attempt to stop the spread and death toll in Singapore, complete lockdowns in homes are implemented to stop the spread of the virus. Along with the huge technological advancements in recent years, the rising demand for energy has exponentially increased. The impact of the pandemic has caused a surge in the energy demand from an increased reliance on technology to cope with the pandemic.
With the revolution of the food industry, food can be easily and quickly grown in labs. Food shortage is no longer an issue. Basic necessities would be delivered through drones that ensure contactless delivery, which brings about instant gratification through quick delivery. Individuals in lockdown will have to stay home and work for food and electricity. Their homes will be powered by the energy they generate from daily scheduled cycling that replaces work. This ensures individuals remain physically fit and healthy as well. Individuals are only allowed to leave their homes under very specific circumstances.
Individuals will be incentivized to monitor one another to deter crime and ensure nobody flouts the rules. The time spent surveying others would be rewarded with the time that one can spend online to interact with others. This system ensures the safety of the residents in their homes through the constant monitoring of their activity and health. Anyone caught attempting to break the rules will be swiftly apprehended and sent to reformation camps. Newly infected individuals are immediately sent to isolated facilities for research and testing for a cure.
This newly established world in 2053 has completely dehumanized individuals.
With increasing surveillance and technology in our modern society, are we already losing our individual identities?
Part 2 of this project takes place five years after, focusing on the post-pandemic landscape. The rebuilding of society led to the Fifth Industrial Revolution taking place, causing drastic social inequality as the wealthy accumulated their wealth and the poor were exploited.
This project aims to critique the issues of social inequality in our society by portraying the responses of the poor as they attempt to climb the social ladder through illegal trade.
With the extreme measures put in place over the past few years, the virus eventually disappeared five years later. Citizens began rejecting the need for mass surveillance. Mass surveillance was reduced and society looks to rebuild itself.
Masses of factories were built and the Fifth Industrial Revolution began, with 3D printing and lab-grown food becoming the key catalysts for the revolution. Due to the possible transmission of diseases through animals and also the heavy reliance on lab-grown food over the years, the consumption and production of organic meat are banned in Singapore to prevent another pandemic.
Multiple jobs were replaced with autonomous technology and advanced AI, many lost their jobs. Wealthy companies capitalised on the revolution and began dominating the industry. Where the jobs were available, the corporations exploited the workers by paying low wages for long hours. The wealthy were favoured while the poor were marginalized and struggled to survive. As the social class gap grew wider, political unrest ensued and various groups were formed to oppose the government.
Despite the ban, there was a high demand for organic meat in black markets. In desperate attempts to make ends meet, the lower class took risky ventures to smuggle organic meat and open illegal eateries and restaurants. As the food was difficult to obtain, it was sold at high prices only the rich could afford. Some used their own businesses as a facade to mask their illegal trade and were able to bribe law enforcements when their dealings were discovered.

Expanding Latin American Political Threat: June 2021
Economic Stagnation, Politics Stress: Before the coronavirus pandemic, political tension and social discontent were already building. Adhering to continuous economic progress plus an expansion of the center school in the commodity growth years, national expansion averaged just 1Percent while in 2015-2019. Five years of monetary stagnation led to protests in some countries in 2019. The pandemic and tough lockdowns typically muted unrest in 2020. As countries in the region begin to reopen, social grievances have returned to the forefront. Poverty Surges, Inequality Continues to be Substantial: ECLAC estimates local poverty elevated by 3.2% to 33.7Percent in 2020, environment the location back again 12 yrs. Poverty levels bottomed out at the conclusion of the product extremely pattern in 2013 along with been increasing gradually because. In addition, Latin United states has always been the most unequal among creating territories. Even with enhancements in every places in the region since 2002, inequality remains rich in most nations. Continued high unemployment due to the pandemic, especially amid younger years, can also be adding to societal discontent.

“Jewish musicians used to play frequently at non-Jewish weddings and festivities where they undoubtedly played Jewish tunes in addition to the Ukrainian dance-repertoire. In the same way they brought their Ukrainian repertoire to Jewish weddings (e.g., kozačkesskočnas).” Beregovski 1935 [= Beregovski/Slobin 1982, p. 526]. (Musical notation included).
“Let us introduce another example, a dance such as the kozak (kozačok), which was and still is widespread among Ukrainian Jews and also in Poland. There can be no doubt about the Ukrainian origin of this dance among Jews outside the Ukraine (in Poland) and to determine those features introduced by the Jews; we find such features in this music... It is noteworthy that in both belles lettres and folklore the kozačok is mentioned much more frequently than the šer. Is this perhaps because the kozačok was a male dance (though also a female dance) that was performed at the wedding in the presence of all the guests? The kozačok was basically a solo dance in which the more talented dancers could distinguish themselves.” Beregovski 1937 [= Beregovski/Slobin 1982, p. 535]
“Daddy, daddy, the groom approaches...we are going to dance a kozak.” [Warsaw, Poland, pre-World War I]. Cahan 1957, pp. 245-46 (#263)
“Also a ‘kozak’ [and a freylekhs]... were folk-dances for adults and in-laws. The youth strutted its wards in waltzes, krakoviaks, etc.” [Dubno, Poland, pre-World War II]. Katshke 1966, p. 667
“‘...Let’s dance the kozak;’... The melody is that of a ‘Polish mazurka.'” [Galicia, 1920s-30s]. Pipe 1971a, pp. 161 (#48), 307 (#48)

What is the unit of the molecular weight?
In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Subsequently, one may also ask, how do you figure out molecular weight?
Go to periodic table and determine the atomic mass average (atomic weight) of each element. Multiply each atomic mass by the number of atoms in the formula. Add up the results of step three: 2.015+32.066+63.998 = 98.079 = molar mass of sulfuric acid.
What is the molecular weight of DNA?
Molecular weight of a double-stranded DNA molecule = (# of basepairs x 650 daltons)
How do you find molecular weight of a gas?
To determine the molecular weight of a gas, we measure the volume, temperature, and pressure of a known mass of a gas. We can use the Ideal Gas Law to calculate the number of moles of gas we have, and then divide this number into the mass to get the molecular weight.

Susan B. Anthony: Suffragist And Feminist Activist
Susan B. Anthony was undeniably one of the most influential suffragists and feminists of all time. Raised a Quaker, Anthony was from a household that stressed the equality of men and women, unlike many of her suffragist peers. Her father also let her do many hard jobs and sent her off to boarding school, where the stern headmistress, who always found faults in whatever Anthony did, helped build her zeal for success. These character building upbringings impacted the way Anthony would campaign for women’s suffrage in years to come. Because of her teaching job, Anthony knew of the unequal pay between men and women. When she was teaching, men would often be paid better than her. In a speech she once gave, she said, “Would you make it more lucrative, increase the salaries of the women engaged in the noble work of educating our future Presidents, Senators, and Congressmen” (Sherr 19-20). As she grew older, Anthony became a passionate suffragist, abolitionist, and supporter of the temperance movement. Her view is easily summed up in her work, the History of Woman Suffrage, “This society including our systems of jurisprudence, civil and political …show more content…
Anthony continues to be one of the most influential women in the suffragist and feminist movement. Her arguments stay relevant and can be applied to the inequalities women face today. Her hard work still influences many young feminists today. Her remarkable approach to the suffrage cause was made possible through her lasting suffragist friendships, her numerous committees set up for women’s franchise, and her influential writings. During her lifetime, Anthony fought hard for the woman’s right to vote and, although she never lived to see it, the 19th Amendment to the U.S. Constitution is eventually passed in 1920. She knew that with the right to vote, women could change the world. She knew they would not be unsuccessful. When she retired in 1900, she left her fellow suffragists with these words: “Failure is

# Challenge Here is some code that does a checksum over a string `s`: ```python def checksum(s): v = 0x1505 for i in xrange(len(s)): v = 33 * v + ord(s[i]) return v FIND_THIS_STRING = "???" checksum(FIND_THIS_STRING) & 0xFFFFFFF) == 0xf5c10af ``` Your job is to find a string `s` (using z3) that satisfies a checksum `0xf5c10af`. Specifically, your string should cause the following to be true: `checksum(FIND_THIS_STRING) & 0xFFFFFFF) == 0xf5c10af` **Don't brute force it, that will take too long.** The set of possible characters is `0-9a-zA-Z`. I'm not telling you the length. You can check for the right answer using the checksum code above. When you think you have it, submit it to the server which will check your answer. You can talk to it like this: ``` nc clegoues-ubuntu-vm1.andrew.cmu.edu 7777 ``` or with telnet (if you use windows): ``` telnet clegoues-ubuntu-vm1.andrew.cmu.edu 7777 ``` Note: Use __[bitvectors](https://rise4fun.com/z3/tutorialcontent/guide#h25)__ and not int variables; the latter may make life needlessly difficult. Use a bitvector length of 32. See below for example code... ## Python API While you can solve this using the web interface, its highly recommended you use the python library which: (a) takes care of casting bitvectors to the right length and (b) lets you use infix notation for arithmetic expressions. You can declare bitvector variables in python like this: ``` my_bitvector_variable = BitVec('x1',32) ``` Here's a boilerplate code to get you started: ```python from z3 import * oracle = 0xf5c10af x1 = BitVec('x1', 32) x2 = BitVec('x2', 32) constraints = [] constraint_x1 = x1 < 99 constraint_x2 = x2 > 20 constraints.append(constraint_x1) constraints.append(constraint_x2) # The above two lines is the same as using logical 'And' included in z3, used like this: # constraints.append(And(constraint_x1, constraint_x2)) s = tuple(constraints) print "Constraints: ",s print "Solution?" solve(*s) ``` If you have z3 set up correctly, you should see: ``` Constraints: (x1 < 99, x2 > 20) Solution? [x2 = 21, x1 = 98] ``` ## Hint
Click to expand a hint The idea is to build up constraints based on the checksum function. Let's pretend our string was simply "a". The checksum will calculate: `v = 33 * 0x1505 + ord('a') = 177670 = 0x2b606`. How about if our string was "ab"? The checksum will calculate: `v = 33 * (33 * 0x1505 + ord('a')) + ord('b') = 0x597728` And so on. So `checksum` can be summarized by a bunch of constraints on some number of characters. We can express the constraints and use symbolic variables for the characters. Here is a z3 example for the one character case, where we want to solve some character for the checksum `0x2b606`. Above, we know that "a" will work. Can z3 tell us this? ``` (declare-const x (_ BitVec 32)) (assert (= (bvadd (bvmul #x00000021 #x00001505) x) #x0002b606)) (check-sat) (get-model) (exit) ``` (Note that in online z3, the bitvector lengths must all be the same. One more reason to use the python API instead, which handles this automatically for you!) This gives the solution ``` sat (model (define-fun x () (_ BitVec 32) #x00000061) ) ``` No surprise, `0x61` is the ascii character `'a'`. You can see this by printing `ord('a')` in python. Here's a program that solves two characters for the checksum `0x597728`: ``` (declare-const x1 (_ BitVec 32)) (declare-const x2 (_ BitVec 32)) (assert (= (bvadd (bvmul #x00000021 (bvadd (bvmul #x00000021 #x00001505) x1)) x2) #x00597728)) (check-sat) (get-model) (exit) ``` Solution: ``` sat (model (define-fun x2 () (_ BitVec 32) #x00000000) (define-fun x1 () (_ BitVec 32) #xc1f07c83) ) ``` Oh! z3 gives us a strange solution. `x2` is `0x0` and `x1` is `0xc1f07c83`. While that satisfies the constraints, we can't represent `0xc1f07c83` in ascii. Can we add more constraints to convince z3 to give us a reasonable solution?
## Hint 2
Click to expand another hint What if we tell z3 that the variables must be within ascii printable range? `z` is the value 122, or 0x7a. We can tell z3 that `x1` must be less than or equal to that: `(assert (bvule x1 #x0000007a))` (In python, we can simply add the constraint `constraint_x1 = x1 <= 0x7a`)

Images sent back from the Galileo spacecraft provide hard evidence that asteroids can have satellites, according to a letter published in Nature magazine Wednesday.
Clark R. Chapman, of the Planetary Science Institute in Tucson, Arizona, and colleagues have studied images of the asteroid 243 Ida and found a satellite, named Dactyl, with a diameter of one mile, around it.The scientists said astronomical observations at the time a star is eclipsed by an asteroid suggested asteroids might be circled by satellites, but up to now there has been little hard evidence to back this up.
They said that Dactyl physically resembles Ida and other members of the Koronis asteroid family some 280 million miles from the sun and may have been formed when the Koronis parent body broke up.
Dactyl is slightly less red than the Ida asteroid, but the color differences are of a similar magnitude to variations among various Koronis family members, they said.

Letter: Do our elected officials understand the importance of hedge funds?
Seth Wenig, Associated Press
Now more than ever, our state’s retirees, charities, and college scholarships deserve financial security and certainty. COVID-19 upended long-term growth plans for these organizations, and as we recover from this global pandemic, they are looking to regain their footing after a year lost. We must ensure pensions, nonprofit and university endowments have a clear recovery path. These organizations invest in hedge funds, which play a critical role in their long-term financial stability.
Pensions, endowments and other institutional investors depend on hedge funds, a misunderstood but important aspect of Wall Street, to secure their financial well-being. Hedge funds employ sophisticated market strategies to generate stable, durable returns on investment for entities like Utah Retirement Systems, which invest over $5 billion for 224,290 plan participants. Hedge funds play a crucial role in growing these investments over time, and the gains made from these investments benefit ordinary Americans.
I hope our elected officials recognize and understand this. Recent scrutiny from Washington, D.C., has made it clear that some politicians don’t understand how hedge funds work. Their misguided tax proposals demonstrate a lack of understanding of a simple but important concept: Hedge funds work on Wall Street but deliver for Main Street.
