Sooner or later, your robot is going to crash into something. It might fly off your workbench because you forgot to put a block underneath it before you flipped the power switch. It might make a wrong turn and head down the staircase. But it seems to me more likely that a simple programming error or communication failure will cause the robot to continue moving after it should have stopped, resulting in an unplanned encounter with a wall, a door, or some other solid object.
This article most certainly does not offer a way to prevent collisions; this would require a sensor that can detect the presence of a rapidly approaching object. The present objective is to detect collisions, i.e., enable the robot to realize that something bad has happened and then take appropriate action.
The automated response could be to send a distress signal, disable the power supply, or initiate a self-test procedure that attempts to evaluate the nature of the damage. In this article, though, we'll keep it simple: if a collision is detected, the robot stops the motors. This at least avoids the situation in which a confused or wounded or half-ruined robot continues careening at high speed until finding another solid object or otherwise exacerbating the damage suffered in the initial crash.
We'll need two articles to fully address this topic. This current article describes the development procedure and leaves you with firmware that is just what you need for bench-testing and refining your algorithm. In the next article, we'll attempt to collect real collision data and fine-tune (or overhaul) the algorithm accordingly, and the final firmware will be intended for independent robot operation.
If you'd like to catch up on how I built my robot for this project, please read the articles below:
It should come as no surprise that a collision involves significant acceleration (specifically, deceleration). Thus, with proper signal processing we can use the accelerometer data to detect a collision event, and then the microcontroller can stop the motors.
Damaging events could theoretically originate from any direction, especially if your robot will be subjected to one of those contests where people build machines that become instruments for safely expressing the long-standing tendency of humans to attack and kill one another. However, in this project, we will assume that a collision will always consist of a forward-moving robot crashing directly into a solid object. This means that the acceleration will be in the reverse direction, which (as mentioned in this article) corresponds to the accelerometer's positive x-axis.
We'll use the EFM8 microcontroller's internal 14-bit ADC to digitize the analog acceleration signal. Here is the configuration:
- The sample rate is 1 kHz, which is significantly higher than the bandwidth (~200 Hz) of the accelerometer signal.
- Since we are concerned only with the type of collision described above, we ignore the z-axis and the y-axis; the ADC input signal is always the x-axis output, which is connected to P1.7.
- We will be using the ADC's automatic accumulate-and-divide functionality. This is a simple way to reduce noise and hopefully make it easier to identify a low-amplitude acceleration event. Every conversion trigger will result in four ADC samples; these are added together and then shifted right by two bits (which is equivalent to dividing by four).
I gathered test data using my custom serial-port-logger application, which is discussed here in the "YAT and Excel" section. However, the current version is greatly improved: it now can send ASCII commands, and it has multiple text-to-be-sent boxes so that commonly used commands are available with just a single click.
This code excerpt gives you the functions associated with the three-letter ASCII commands:
char RecordAccelerometerData = "RAD"; char TransferAccelerometerData = "TAD"; char EnableCollisionDetection = "ECD"; char DisableCollisionDetection = "DCD"; char SoftwareReset = "SWR"; char MotorsFullForward = "MFF"; char DisableBothMotors = "DBM"; char BrakeBothMotors = "BBM";
I use the following Excel file to process and plot the acceleration data:
Let's Look at Some Data
I used my hand to produce a backward acceleration event that hopefully is somewhat comparable to the rapid deceleration caused by a collision. (The technique is demonstrated in the first video.)
Here are three data sets:
I put these waveforms next to one another and identified two characteristics that they all have in common:
- The acceleration signal rapidly exceeds 1660 mV, which is also significantly above the noise floor.
- They all maintain a high slope until at least 1670 mV.
Thus, I built my algorithm around these two values: the detection algorithm begins when an ADC sample exceeds 1660 mV (=11332 ADC counts). It then waits to see if the signal will exceed 1670 mV (=11401 counts) within a certain period of time; the time-to-second-threshold restriction is based loosely on the slope of the initial rising edge seen in these three waveforms.
I quickly discovered that my first algorithm was a total failure: a light tap on the front of the robot chassis was being identified as a collision event. It turns out that a light tap produces an acceleration profile similar to this one:
The amplitude is quite high, but the duration is very short. I realized that I needed to incorporate a minimum-duration condition: if the acceleration falls below the first threshold too soon, the event is ignored. I set the minimum duration (starting with the second-threshold crossing) at 30 samples, i.e., 30 ms. This is shorter than the typical duration from second threshold (rising) to first threshold (falling) for a simulated collision event, yet it seems to be consistently longer than the corresponding duration for the spikes generated by tap events.
The following video shows some initial success with the revised algorithm. The green LED indicates that collision detection is active, and the red LED illuminates immediately after a collision signal is identified. As you can see in the video, taps are successfully ignored and simulated collisions are correctly identified.
Disabling vs. Braking
If you look at the code you will see that I use the function BrakeMotors() in response to a collision event. In this case, it is important to stop the robot as quickly as possible, and thus we use the MAX14870's brake mode instead of simply disabling the motors:
From the MAX14870 datasheet.
The following video conveys the difference between stopping the motors (by setting the nEN pins to logic high) and braking the motors.
You can use the following link to download the source and project files:
The comments and descriptive identifiers will help you to understand what's going on.
Note that the collision detection algorithm is located in the ADC0WC (WC = "window compare") interrupt service routine (in the "Interrupts.c" source file). You can read more about the window-compare functionality in the EFM8LB1 reference manual. It's a handy feature because it allows the initial threshold detection to occur automatically, i.e., the CPU doesn't have to compare the ADC samples to the threshold or do anything else related to the ADC conversions. The ADC operates independently and doesn't bother the processor at all until a sampled value has exceeded the first threshold.
Final Bench Testing
The following video shows a successful simulated operation of the collision detection functionality. (The acceleration signal is very different when the motors are running; we'll look at that in the next article.)
We've developed a collision detection algorithm and confirmed that it correctly identifies simulated collision events. It also can ignore high-amplitude, short-duration acceleration signals resulting from a rapid, localized impact (i.e., a tap). The next step is to gather data from and test functionality with real collisions.

Summary: Interpreting classical theories
in constructive ones
A number of classical theories are interpreted in analogous theories
that are based on intuitionistic logic. The classical theories considered
include subsystems of firstand second-order arithmetic, bounded arithmetic, and admissible set theory.
Proof theory was developed, in part, as a way to reconcile classical and constructive aspects of mathematical reasoning. Given this historical fact, it is not
surprising that over the years proof theorists have invested a good deal of effort
in reducing classical theories to constructive ones.
Elegant in its simplicity, the GĻodel-Gentzen double-negation interpretation
works wonders. For example, it seamlessly reduces classical arithmetic to its
intuitionistic counterpart, and with some additional work it can be used to interpret Zermelo-Fraenkel set theory in a variant based on intuitionistic logic.
Under the double-negation interpretation, 2 sentences of arithmetic, which can
be said to carry a theory's "computational" content, are not preserved, but in
both these examples a further application of the Friedman-Dragalin interpreta-

Psychology professor co-authors study on tennis grunting effectsUniversity of Hawaiʻi at Mānoa
Posted: Oct 1, 2010
You've heard them at tennis matches – a loud, emphatic grunt with each player's stroke. A University of Hawai'i at Mānoa researcher has studied the impact of these grunts and come up with some surprising findings.
Scott Sinnett, assistant psychology professor at the University of Hawai'i at Mānoa, has co-authored a study on the potential detrimental effect that noise has on shot perception during a tennis match.
Sinnett's work was published today in an online issue of Public Library of Science ONE. He co-authored the study with Alan Kingstone, psychology professor at the University of British Columbia, to determine if it is reasonable to conclude that a tennis grunt interferes with an opponent's performance.
As part of the study, thirty-three undergraduate students from the University of British Columbia viewed videos of a tennis player hitting a ball to either side of a tennis court; the shot either did or did not contain a brief sound that occurred at the same time as contact.
Participants were required to respond as quickly and accurately as possible, indicating the direction of the shot in each video clip on a keyboard. The extraneous sound resulted in significantly slower response times, and significantly more decision errors, confirming that both response time and accuracy are negatively affected.
"This is the first study to look at the issue of grunting in tennis. Our current work is also looking at how advanced and professional tennis players perform, to determine if they have developed any strategies to limit the negative effects of a grunting opponent," said Sinnett.
While these findings must still be validated on the tennis court, Sinnett and Kingstone noted that these consequences on faster tennis surfaces, such as the grass courts of Wimbledon or hard courts of the Australian and U.S. Open, are likely to be profound.

Norn Genetics
In this activity we will explore genetic principles using "Norns" as a subject. For each of the cases below, you will need to follow the instructions and keep a log of your progress (questions are included in the module).
1. Simple Norn Genetics
2. Norn Genetics and Sex-linkage
3. Norn Genetics - Multiple Allele Trait
These activities were created for the purpose of teaching introductory biology classes on the topic of genetics. As this is my first attempt at flash, I realize there are some improvements that can be made, but for now it works for the purpose that it was intended for.
History of the Norn
Norns (Cyberlifogenis cutis) are a species of creature, created by the Shee to entertain them and serve tea and biscuits. They were genetically engineered on the disc-shaped planet Albia. Many were abandoned there as the Shee took off in their spaceship, the Ark (although they took a few of them along). They are lovable and innocent creatures, who need some care to survive, though some breeds are more capable of living in the wild.

How to Eliminate Foul Odor in Hunting Boots
Out there in the wilderness, you need to use the hunting boots in any weather condition. Humid conditions or wet conditions can lead to unhygienic hunting boots. Consequently, there might be a foul odor in your hunting boots. It is essential to maintain the boots in a hygienic condition.
Only once you do so will you be comfortable.
Today we will share the answer to the question of how to eliminate foul odor in hunting boots.
How to eliminate foul odor in hunting boots?
We will share with you a step-by-step way to eliminate such odor from your hunting boots.
 1. The first thing is to wrap a bit of bicarbonate soda in a thin cloth. You have to keep it in your hunting boots. You should keep it in the hunting boots for at least 12 hours.
 2. After doing so, you can place blotting paper inside the shoes. You have to add some cloves to it. It can mask any odor with its own fragrance.
 3. After a few hours, you have to remove the same and keep the shoes in an airtight plastic bag. You have to keep the plastic bag in the freezer for 3 to 4 hours. It will kill the odor-causing bacteria right away.
 4. Once you have done so, you have to dry the shoes in your balcony or in your lawn.
These four simple steps will certainly help you eliminate the foul odor in hunting boots.
Alternative method:
In case your hunting boots can handle water, you can use this alternative method as well. The alternative method will certainly help you clean the boots inside out. Once you do so, you will not have to worry about odor.
 1. You have to first and foremost, rinse your boots from outside. For the inside, you have to use a damp cloth to wipe them clean.
 2. Thereafter, you have to create a mixture of water in commercials and Tiller. You have to spread all over the boots.
 3. Once you do so, you have to let the boots dry for a few hours.
 4. After that, you have to remove the insole and wash them with detergent. You have to make sure that the detergent is scent-free. After that, you have to let the insole dry as well.
 5. If you do not want to spend hours drying the boots, you can buy an extra pair of boots. Once you do so, you will be able to dry the boot in no time.
These are the two methods that you can use to eliminate foul odor from hunting boots.
To prevent foul odor, there are a few precautions that you can take as well.
Precautions to eliminate foul odor in hunting boots:
The precautions that you need to undertake are:
 1. Choosing the right socks:
You always have to choose fresh socks. You have to ensure that there is no odor in the socks. If you wear smelly socks and wear the hunting boots, the boots will develop foul odor.
 1. Allow the boots to dry:
Whenever you wear the boots, socks, or feet get wet; you have to dry them. Only once they are dried, there will be no water and wetness inside the boots.
 1. Inspect your boots from time to time:
Many boots are susceptible to mildew, algae, and so on. You have to inspect the boots from time to time. The purpose of the inspection is to ensure that there is no growth in the boots. If there is any growth, you have to use disinfectants to eliminate it. Doing so will ensure that odor will no longer be a problem.
 1. Regular odor elimination:
At the slightest hint of order, you have to use any of the above two methods to eliminate water. If you do not do so, the odor will become stronger over time. Due to this reason, every time you use your hunting boots, you have to check them for odor.
Once you take these precautions, you will ensure that your hunting boots do not develop any foul odor.
In case they still do, you can use any of the methods we have highlighted above to eliminate odor. Both of these methods are incredibly effective. In a nutshell, after going through this article, you need not worry about water in hunting boots at all. You can always have hygienic hunting boots for your next hunting trip. It certainly eliminates the need to have a spare pair of hunting boots as well.
We will be happy to hear your thoughts

Even if they manage to avoid the obstacle of the turbine blades, the turbulence leaves fish stunned and vulnerable to predators when they emerge at the end of the power plant. In hopes of giving fish an easier ride, engineers are working with GE Renewable Energy to build more fish-friendly hydro turbines in the Columbia River, which separates Oregon and Washington.
The high-tech project — which marries computer modeling with the latest turbine technology — could become a blueprint for hydropower plants around the globe. "We use a digital model, based on computer-fluid dynamics, to simulate the water flow through the turbines," says Kristopher Toussaint, a hydraulic engineer with GE Renewable Energy. "We also have something that simulates a physical particle representing the fish to see, if it impacts components, what pressure that particle is exposed to, and so on."
If you're not a fish, hydro plants might look benign enough: They work by harnessing the force and pressure of water flowing from a high point to a lower point through chutes in a dam. Near the bottom of the chute sits a turbine. The water spins the turbine, which creates power that can be transmitted to businesses and homes. But this is also the main passage for the migrating fish.
Using the digital model, the team discovered that fish are particularly vulnerable to injuries when they pass through a first grid of stationary vanes, then another grid of movable vanes and finally through the blade channels of a runner in rotation. If they survive from the risk of strikes, they still have to bear the rapid pressure drop that occurs inside the runner. (See illustration below.)
To lessen the risk of strikes, one strategy is to align the two sets of vanes and shrink the gaps between rotating parts and stationary parts. Using modeling technology, engineers were able to figure out the optimal vane geometry to minimize the risk to the fish while keeping a smooth hydraulic passage for the flow of water. "Reducing the risk here for the fish is not detrimental to turbine efficiency," says Laurent Bornard, a hydraulic consulting engineer at GE Renewable Energy.
To reduce the pressure drop in the runner, several strategies are usually possible, including changing the number of blades or the runner diameter to reduce the flow velocity and then increase the pressure.
But even if a salmon makes it past the vanes and the runner, its troubles aren't over. To reach the river downstream of the power plant, it still has to go through the diffuser. "The flow deceleration inside the diffuser can create whirlpools and flow detachment that spin the fish around, disorienting them and making them easy prey for predators outside the power plant," Bornard says. In order to prevent fish injury, the engineers typically optimize the flow characteristics delivered by the runner and seek, in some extreme cases, to modify the diffuser geometry to reduce the flow turbulence and make the fish passage as smooth as possible.
As a result of the design changes, engineers expect the survival rate of salmon to improve. And the further potential for the fish-friendly technology is, well, dizzying. "There are close to 10 power plants on the Snake and Columbia rivers that are especially concerned by fish passages during the salmon migration," Bornard says.
GE is also working to make hydro turbines along the Mekong River in Southeast Asia safer for fish that pass through it.

There's No Future in Technology or Sustainability Unless These 4 Things Change
There's no future in technology or sustainability without mining. Unless some things change, the industry won't be able to meet global demand over the coming decades.
Opinions expressed by Entrepreneur contributors are their own.
It's a bold statement, but it's true: Without mining, there is no path to sustainability. The resources required to support modern life and the production of new technologies will come from responsible mining. Thus, mining will ultimately drive the global movement to meet sustainable development goals focused on improving the quality of life for all people. It's a tall order, but it's not impossible. However, some things will have to change to meet the ever-increasing demand for natural resources:
1. Lack of education
There's a massive disconnect between the public's perception of mining and its desire for progress. People want electric cars, clean energy and new smartphones every year. You can't have these without raw materials, which come from mining the earth. To meet the future demand for materials like copper, cobalt and lithium, mining outputs will have to increase by up to 500% over the coming 30 years.
Mining is necessary for our survival but dangerous if not done correctly. The mining industry has made great strides in recent decades to improve its operations and increase overall efficiency to ensure the safety and well-being of people and the environment. However, uninformed public perception and over-politicization can lead to counterproductive policies and regulations. The result is endless red tape that prevents the development of new mining operations that the world greatly needs. It currently takes over a decade just to permit a new mine in the US. We can't afford such crippling delays, which are born from ignorance rather than informed decision-making. Promoting education and advocacy for better understanding of mining's role in sustainability is key.
Mines create jobs and fuel the growth of local economies, not only for the lifecycle of the mine but for generations. The key is ensuring stakeholder participation at the community level that is supported by sound governance and strong institutions. With greater public support, mining can continue to advance and become the catalyst for the truly sustainable development of our societies.
2. Poor policies
The delays caused by poor policy are bad enough, but the current political and regulatory climate surrounding mining has even greater negative impacts on a global scale. Because it is so difficult to mine legally, we now see widespread illegal mining operations worldwide. These operations are extremely harmful; they destroy pristine natural locations, disregard environmental concerns, risk global stability and are rife with human rights violations.
Even when politicians understand the issues around mining policy, the political backlash of supporting a more pragmatic approach makes them hesitant to act. This hesitation is understandable, but it puts political interests above the well-being of their constituents. Mining has become a political football for both sides of the aisle, and this cannot continue. We must review government policies regularly to ensure this industry can continue to support modern life now and in the future.
3. Not embracing the future
Mining also needs to fully embrace emerging technologies, such as machine learning and Artificial Intelligence, to optimize water and energy use, minimize waste and support further exploration. It will continue to be more difficult to extract the materials we need, as the most easily accessible resources have largely been extracted. We'll have to dig ever deeper into the earth for the resources we need, and as we go deeper, the environment becomes more hazardous for humans. That's where AI, machine learning and autonomous machines can mitigate risk and improve efficiency.
We are innovating, to be sure — one good development is our ability to extract minerals from mining waste, for instance.
4. Forced labor
Forced labor in mining is a horrible reality, specifically in countries with less-than-stellar human rights records. With the advantages that low labor costs bring, certain nations have allowed predatory actors to gain access to the market of mining, processing, smelting and refining of our natural resources. Children, the poor and other disadvantaged populations are most at risk.
Developed countries have to take a strong stand against these practices. Only by working together can we end these inhumane practices for good and ensure mining operations are done responsibly in all corners of the world.
We have a powerful incentive to improve mining operations. The future of mining is bright, but that will come with work. If we want to keep providing the building blocks of modern civilization, these things need to change. The benefits are beyond question — we can elevate the poor through minerals and metals, giving them access to electricity and clean water. It's possible to eradicate poverty without giving up civilization while still pursuing clean energy goals. Above all else, health and education are most essential for the sustainable development of humanity. They are the foundation for healthy civilizations, and mining can help us get there.

Globe-Trotting Gnome Highlights Earth's Weird Gravity
Here, the gnome is standing at the Antarctic South Pole. Turns out, the gnome (and you) weighs more at the South Pole than at the equator.
There aren't too many gardens at the South Pole. But there are, apparently, garden gnomes.
A globe-trotting little garden gnome dubbed "Kern" recently visited Amundsen-Scott Research Station at the geographic South Pole in Antarctica. The inanimate traveler's trip was a take on the "Traveling Gnome Prank," a joke that's been in vogue since the 1980s, when pranksters started stealing garden gnomes and sending photographs of the statuettes in front of famous sightseeing spots to their owners.
Kern's travels have a scientific bent, however. The precision scale company Kern & Sohn is teaming up with schools and research stations worldwide to highlight the variations of gravity across the globe.
"Most people don't realize Earth's gravity actually varies slightly," Tommy Fimpel, one of the experiment's coordinators, explained in a statement. "One of the main causes is variations in the shape of the planet. Believe it or not, the Earth is actually slightly potato-shaped, so you'll weigh up to 0.5 percent more or less, depending on where you go."
Even glaciers can change an area's gravity; a mysterious dip in gravity over Canada is likely the result of now-melted glaciers that left behind an imprint from which Earth is still rebounding.
"We thought our Gnome Experiment would be a fun way to measure the phenomenon," Fimpel said.
So far, Kern has traveled, via the mail, to places as far-flung as Lima, Mumbai, Mexico, South Africa, San Francisco, New Caledonia, Sydney and the South Pole. [Photos of Globe-Trotting Gnome]
At the South Pole, where Kern landed last month, the gnome tipped the scale at 309.82 grams, his heaviest measurement yet. That's because the inertia produced by Earth's rotation is stronger at the poles, said Marie McLane, a researcher with the United States Antarctic program and Kern's "host" on the visit to Antarctica. Earth is also slightly squished in shape, with a bulge at the equator, so the planet is less thick at the poles, also contributing to a stronger gravitational effect.
Kern jetted off to Japan after hitting Antarctica, weighing in at 307.9 grams in Tokyo. His next stop is at Snolab in Canada, an underground research station 1.2 miles (2 kilometers) below the Earth's surface. From there, Kern will visit the Large Hadron Collider, the world's largest particle accelerator, at CERN near Geneva.
Kern's journey to Antarctica didn't only highlight the gravitational vagaries of Earth; it also shed light on the planet's elusive garden gnome population. The gnome's visit inspired McLane to do some detective work around the Amundsen-Scott Research Station. She found five little gnomes already lurking in labs and other spots around the station — including one, fittingly enough, guarding a greenhouse.
Kern's progress can be tracked at gnomeexperiment.com.

Sign the Petition to World Wildlife Fund
I want to join the thousands of others who are declaring that Virunga
too valuable to be destroyed for short-term financial gain.
park should remain protected and unexploited.
WWF (World Wildlife Fund / World Wide Fund for Nature)
My inspiration to become a conservationist came 20 years ago, when I was deep in the pristine forest of Virunga National Park, which I like to call "the Yellowstone of Africa." Found along the equator, on the western edge of the Democratic Republic of Congo (DRC), the park is rich with a canopy of trees. It was the sounds of the gorillas and the stories of the people who rely on the natural resources of the park that made me want to work in Virunga--and worldwide--to protect the environment for people and wildlife.
That's one of the reasons why I am so disheartened that British oil company Soco International PLC plans to explore for oil inside the park. Virunga National Park is Africa's oldest national park. It could soon become the continent's newest oil field if we don't speak up.
Take Action: Join the thousands of people who have told Soco to publicly commit to a permanent stop to all oil exploration within Virunga.
The park is also important for people and the local economy, as more than 27,000 people fish in Lake Edward and it provides drinking water to 50,000 people. Countless more benefit from locally sourced fish, renewable energy and other park-related activities. A new report finds the park is worth more than $1.1 billion annually if it is developed sustainably, rather than being given over to potentially-damaging oil extraction.
Take Action Today: Tell Soco to publicly commit to stopping all exploration within Virunga. Permanently.
WWF also calls on the DRC government to uphold its laws prohibiting environmentally harmful activities in protected areas. If Virunga falls, it could be the first of many dominoes to tumble. Parks throughout Africa could also see their protected status slip away. Join us in drawing a line in the forest by telling Soco that Virunga is off-limits for oil exploration.
Thank you for joining me in this fight to protect Africa's oldest park.

Treat me with some dignity, please.
Most of the time we treat our bodies pretty well, but there are those times when we just don't consider the impact certain behaviors or actions will have on our bodies. This may be especially true in the realm of what we respond to emotionally which does much more than just impact our heads or hearts - it impacts the very fibers of our being. Nothing we think or "feel" is ever without influence in our bodies. Therefore, learning to treat our bodies with dignity requires us learning to rein in our thoughts and to rule over our emotions.
Learn to appreciate and give dignity to your body, not abusing it, as is so common among those who know nothing of God. (I Thessalonians 4:4-5 MSG)
Although our writer may have been referring to the dignity with which we are treat our bodies in a "sexual" sense, there is much to be said about maintaining this same vigilance over our bodies in EVERY sense. When the term "dignity" is used, it generally refers to the sense of "self-respect" with which we treat something. This definitely applies to how it is we treat our bodies - for many an action on our part betrays how little we actually "respect" our bodies.
Abuse of one's body begins in many ways, but if we begin from the top down, it may look a little like this:
- The mind. Whenever we take in thoughts which are irrational and then begin to mull them over and over again, we are disrespecting our minds. God created the mind with many faculties, but one of the most important of these is the ability to reason through issues. By the power of deduction (coming to the conclusion because we add this to that and come up with the solution), we make many a decision. Not all decisions are tempered with wisdom, though. If we are to learn to respect our bodies, we must first learn to respect our minds. This is territory we need to declare off-limits to irrational thoughts which seek to invade our minds, but also those thoughts which seem rational at first, but which don't hold up to the test of scripture. An example of this type of thought is the belief we hold of being "unworthy" and therefore undeserving of the love of God. Truth is - he loved us despite our unworthiness, enough to send his Son when we were still totally unworthy, and through his sacrificial death, we are declared worthy. What God declares to be one way we cannot declare to be another - this is just irrational.
- The mouth. Although closely connected to the mind, the mouth often betrays what is much deeper in the heart. If we are to treat our bodies with dignity, we need to guard what both goes in our mouths, and then rule over what comes out. Scripture points to the truth of "garbage in, garbage out". If we think we can have good come forth when all we put in is pretty much junk, we have been deceived. The mouth works closely with the mind and the emotions (heart). What is manifest through our mouth often betrays how it is we actually "respect" or "disrespect" what God has and is doing in our lives. We betray our lack of thankfulness, or perhaps our lack of trust, by the words we speak. The mouth is a portal of entry - so guarding what "goes in" by this portal is also important to the health and welfare of our bodies. Easier said than done - I totally admit that!
- The heart. As I indicated, the emotions are often what plays havoc on the rest of the parts of our bodies. Emotions stir things up, getting the "juices" flowing, so to speak. The volume of hormones released when the emotions get involved would probably blow our minds if we fully understood the response of our bodies to what we allow to affect us through our emotions. If you have ever watched a scary movie and experienced that "edge of your seat" kind of reaction, complete with heart racing a little, then jumped when something scary happened on the screen, you have experienced the influence of emotions. As irrational as it is for us to react to what is on the TV screen, we do - because our emotions have "interacted" with the plot played out in the show we are taking in. Guarding our heart is how we show respect for it. The emotions are not to be feared, but they are to be guarded and not to be allowed to rule over us. They are to be ruled over by the Spirit.
- The hands, the feet, and all in between. After some time ruminating on the same thoughts (rational or irrational), the body will begin to respond to those thoughts. It is natural to begin to "do" what we think. Engage the senses and you will soon find the other "body parts" responding. What gets thought gets acted out. Learning to respect our bodies involves learning what the right response of ALL our body parts should be - internally and externally. We are given the Holy Spirit to help us with this task. As a matter of fact, scripture reminds us that our bodies are the "temple of the Holy Spirit". In other words, our bodies are a dwelling place for God's Spirit - as such, their actions ought to reflect both the respect for his presences and the gratitude for his grace. We won't get this "right" every time, but as we grow in Christ, we will see our bodies responding more and more in alignment with what the Spirit desires. We have to keep moving TOWARD respect of our bodies and in time, we will begin treating them with the dignity they deserve. Just sayin!

(Image source from: Indian-led team's breakthrough brain development research })
An Indian-origin scientist in Germany has led a team to discover a complex regulatory mechanism explaining the role of a core gene involved in the formation of brain cells. The research throws light on the development of the brain and its potential to be used in regenerative medicine.
A research team reached the breakthrough in Dr Vijay Tiwari lab, at the Institute of Molecular Biology (IMB) in Mainz. The study's lead contributors were Abhijeet Pataskar and Johannes Jung.
The researchers say, "Understanding gene regulatory networks involved in the generation of neurons is a very important question in neurobiology and our findings are an important addition to this knowledge."
Neurodegenerative diseases usually remain incurable. They are characterized by loss of brain cells or neurons. While cells of other body parts of different organs in the human body regenerate, neurons cannot regenerate themselves, which is the prime reason for a variety of neurodegenerative diseases to remain incurable.
Dr Tiwari said, "Our findings are a significant step towards understanding the relationships between DNA sequence, epigenetic changes and (brain) cell fate. This not only sheds light on the mechanisms driving brain cell fate but also opens novel avenues for regenerative medicine."
The research team studied the formation and development of the brain during the embryonic stage. The critical role of single gene, NeuroD1, in the process of brain development was discovered.
Recently, the research paper was published in the EMBO journal.

It takes approximately two and a half 750 milliliter bottles to make a half gallon. To get the number of bottles needed to make half a gallon, the gallon has to be converted to milliliters, divided by 2 to get half of it and then divided by the number 750.
One gallon translates to 3,785.41178 milliliters. This means that 1,892.70589 milliliters make half a gallon. Dividing that value with 750 yields the number 2.523607853. Upon rounding the number to two decimals, the result is 2.52, which represents the number of 750 milliliter bottles that are needed to make half a gallon.


OUJI-CR 5-68
No person may be convicted of forgery in the second degree unless the State has proved beyond a reasonable doubt each element of the crime. These elements are:
First, making/engraving/(causing to be made/engraved);
Second, without authority;
Third, a plate of a (promissory note)/(bill of exchange)/draft/check/(certificate of deposit)/(evidence of debt);
Fourth, issued by a bank;
Fifth, with the intent to use/(permit it to be used) for the purpose of taking therefrom any impression to be passed/sold/altered.
Statutory Authority: 21 O.S. 1991, § 1575.
Committee Comments
The crimes created by sections 1583 and 1584 are very similar in their elements to the crimes created by the statutes discussed under forgery in the first degree and prior second-degree forgery crimes. The Commission did not classify sections 1583 and 1584 under the earlier instructions because making false coins is generally thought of as a distinct crime called "counterfeiting," rather than the crime of forgery. Sections 1583 and 1584 are forgery crimes, however, because of the mens rea element indicated in the third element. In addition, since no Oklahoma cases have construed these two sections, it seemed more appropriate to deal with the sections separately to avoid cluttering the discussion of the forgery statutes normally used in Oklahoma.
Section 1588 creates a "classic" counterfeiting crime, i.e., making a false stamp. Whether the maker intends the stamp as a joke or as a specimen of his artistic skills, he has committed a crime. Section 1588 has never been construed in Oklahoma for the probable reason that the federal government has the paramount interest in protecting the manufacture of currency and stamps.
Section 1575 also seems to create a counterfeiting crime whereby the authority of a bank to issue certain types of documents is protected. Section 1576 is a definitional statute that indicates when a plate has sufficient resemblance to an authorized plate so as to come within the prohibition of section 1575. No Oklahoma cases have construed sections 1575 and 1576.


Great Thessaloniki Fire of 1917
From Wikipedia, the free encyclopedia
Jump to: navigation, search
The fire as seen from the quay in 1917.
The fire as seen from the Thermaic Gulf.
The Great Thessaloniki Fire of 1917 (Greek: Μεγάλη Πυρκαγιά της Θεσσαλονίκης, 1917) was a fire that got out of control and destroyed two thirds of the city of Thessaloniki, second-largest city in Greece, leaving more than 70,000 homeless. [1] The fire burned for 32 hours and destroyed 9,500 houses within an extent of 1 square kilometer. Half the Jewish population emigrated from the city as their livelihoods were gone. Rather than quickly rebuilding, the government commissioned the French architect Ernest Hébrard to design a new urban plan for the areas of Thessaloniki that were burned and for the future expansion of the city. The designs of Hébrard are still evident in the city, most notably Aristotelous Square, although some of his most grandiose plans were never completed due to a lack of funds.
The city before the fire[edit]
Thessaloniki in the late 1800s.
Thessaloniki was one of the largest and most modern cities in Europe by Balkan standards at the time of the fire. By European standards, the city's planning was chaotic and the unhygeinic conditions that prevailed in the poorer areas were described as "unacceptable" by the government in Athens.[1] The city's harbour was one of the most important centres of trade in the region. In 1912 the city, along with the biggest part of Macedonia and Epirus, was incorporated in Greece. The population of the city was essentially maintained: the larger part of the population were Sephardi Jews, followed by Turks, Greeks, Bulgarians, Roma and others.
As soon as World War I began in 1914, Greece maintained neutrality. With authorization by the government, Entente Forces had landed troops in Thessaloniki in 1915, in order to support their Serb allies in the Macedonian Front. In August 1916, Venizelist officers launched an uprising that resulted in the establishment of the Provisional Government of National Defence in the city, essentially dividing Greece into two sovereign states, one represented by Eleftherios Venizelos, and the other by King Constantine. After King Constantine abdicated in June 1917, Greece was reunified again.
Thessaloniki soon became a transit center for Allied troops and supplies, and the city filled with thousands of French and British soldiers, numbering up to 100,000.[1] The population of the city at the time is dubious, with some sources claiming around 150,000 and others 278,000.[1] French navy official Dufour de la Thuillerie writes in his report that "I saw Thessaloniki, a city of more than 150,000 people, burn".[1]
The fire[edit]
Start of the fire[edit]
Aerial picture of the fire.
According to the findings of the investigation by the Court of Thessaloniki, the fire began on Saturday 5 (OS) /18 August (NS) at roughly 15:00.[1] It began by accident at a small house of refugees at Olympiados 3, in the Mevlane district between the center and the Upper City.[1] A spark from the kitchen fire fell in a pile of straw and ignited it. Due to lack of water and indifference, the initial fire was not put out. Eventually, an intense wind caused the fire to be carried to the neighboring houses, and it continued throughout central Thessaloniki.[2]
Initially the fire followed two directions, to the Residency via the road of Agiou Dimitriou, and to the market via the Leontos Sofou road. The Residency was saved by its employees, who hurried to help. The wind strengthened and caused the fire to continue to spread towards the center of the city. In the early morning of the next day (6/19 August), the wind changed direction and the two fronts of the fire destroyed all of the commercial center. At 12:00, the fire passed around the grounds of the church of Haghia Sophia without burning it, and continued eastward up to the road of Ethnikis Amynis (former name: Hamidie ), where it stopped. On the evening of Sunday 19 August (6 August by Julian Calendar), the fire completely died out.[2]
Efforts at firefighting[edit]
Destruction caused by the fire, with the Ministry for Macedonia and Thrace in the background.
There was not enough water for firefighting because the Allied forces controlled reserves to serve their camps and hospitals in the suburbs of the city, which were reduced due to the drought of that summer and the high consumption of the growing population.[2] More significantly, the city government did not have an organized fire brigade; a few firefighting teams were privately owned by insurance companies that protected only their subscribers. The private firefighters were found to be untrained and equipped with old or no equipment.[citation needed]
In the afternoon of the first day of the fire, a French detachment exploded three houses next to the Diikitirio to create a buffer zone or area of safety. However, the French detachment did not continue and ended up withdrawing, leaving the fire to continue on its destructive course.[citation needed] The next morning, two British fire engines and teams stopped the fire near the White Tower. French soldiers saved the customs building.
The Allied forces rejected the idea of interrupting the water supply of their camps and hospitals to use for firefighting.[citation needed] General Maurice Sarrail visited the region of Diikitiriou for a few hours during the afternoon of the first day but he did not return. Several reports noted that French soldiers looted stores and businesses and prevented householders from rescuing their goods.[2] The next day, General Sarrail ordered the execution of two French soldiers who were arrested for selling stolen jewels. The British soldiers assisted in the firefight as long as they could, using military lorries to transport fire victims and their goods to refugee settlements. (Drivers of French cars reportedly asked for pourboire - tips, for the same service.)[2]
A map showing the huge area destroyed by the fire.
The fire destroyed 32% of the total of Thessaloniki, about 1 square kilometer. The burned region was located between the roads of Aghiou Dimitriou, Leontos Sofou, Nikis, Ethnikis Amynis, Alexandrou Svolou, and Egnatia (from Aghia Sofia). This region is reported in official documents as "burned zone" (Greek: πυρίκαυστος ζώνη, pirikafstos zoni) and in the popular narrations simply as "the burned" (Greek: τα καμμένα, ta kammena). The extent of material damage within Thessaloniki was calculated to be worth 8,000,000 golden pounds.
Included among buildings that were burned were the Post office, the telegraph office, the town hall, the water supply and gas company headquarters, the Ottoman Bank, the National Bank of Greece, the deposits of the Bank of Athens, parts of the Saint Demetrius church, two other Orthodox churches, the Saatli Mosque, 11 other mosques, the seat of the chief rabbi with all its archive, 16 of the 33 synagogues, and the printing-houses of most newspapers. Thessaloniki had the highest number of published newspapers in Greece, but after the fire most did not manage to rebuild their businesses and publish again. Approximately 4,096 of the 7,695 shops within the city were destroyed, many of which were Jewish, and 70% of the workforce was unemployed.
Care of fire victims[edit]
The people affected by the fire totaled approximately 73,447. The Pallis Report identified the homeless by the three religious communities of Thessaloniki: 52,000 Jews, 10,000 Orthodox and 11,000 Muslims.[1]
Refugees after the fire.
The care for the fire victims started immediately: Greek authorities constructed 100 houses to shelter 800 families. The British authorities established three settlements with 1,300 tents, where they accommodated 7,000 homeless. The French authorities set up a settlement for 300 families, and built the Union of French Ladies, a smaller camp for 100 families. Together they transported 5,000 people by train for free and relocated the refugees to Athens, Volos and Larissa. The Greek authorities set up distribution points providing free bread to 30,000 individuals. The American, French, and British Red Cross distributed food among the homeless. Nearly half the city's Jews, having lost both homes and shops, soon emigrated to western countries, mainly France and the United States, while some relocated to Palestine.
Pericles A. Argyropoulos, the major government representative, founded the Administration for Victims of Fire for the care of thousands of fire victims; and the government approved credit of 1,500,000 drachmas for the first needs. Simultaneously, the Central Committee for Donations was organized, with a line of sub-committees for the collection of donations and the distribution of money and goods.

Saving energy: California clamps down on 'vampire' chargers
Wasteful battery chargers for smartphones, tablet computers, laptops, etc., will be subject to new, stricter rules in the US state of California.
'Vampire' battery chargers can waste up to 60% of the energy they take from electrical outlets. California is the first US state to confront this problem, with the California Energy Commission voting unanimously to improve efficiency standards, which will cover some 170 million chargers.
The manufacturers of consumer appliances of course strongly objected to the new regulations, despite projections that the improved energy standards would save $306 million per year on commercial and residential electricity bills.
From the Los Angeles Times:
This means that we can have the devices that we like in our lives and that make our lives easier. But by taking a few relatively simple steps to improve battery chargers, we can save so much electricity, take care of the environment and save ratepayers money.
–Commissioner Karen Douglas, California Energy Commissioner
California's energy plan has a tradition of placing a priority on energy efficiency, above the development of renewable power, starting with air conditioner regulations back in 1977. This strategy has helped keep the state's per capita energy consumption the same over the past 30 years, as opposed to the US as a whole, which saw consumption increase by 50% over the same period.
The chargers are called vampires because they continue to suck energy from the wall if plugged in, even when they are not charging their battery-powered devices. (Tip: don't leave your laptop, smartphone, tablet charger, etc., plugged into the wall!).

2019 13th European Conference on Antennas and Propagation (EuCAP)
Publish Year: 2018
Abstract: This paper presents the frequency dependence of the path loss in urban macro-cellular (UMa) scenario under the non-line-of-sight (NLOS) case. The mobility measurements in two different cities are conducted to obtain the path loss at 2.54, 3.5, 4.9, and 5.4 GHz. Some special UMa environments are illustrated. Furthermore, their path loss characteristics and the reason for causing this phenomenon are analyzed. Comparison of the frequency dependence coefficient (FDC) in different environments are performed. The results show the values of FDC remain stable in different UMa environments under the NLOS case while other parameters of fitting results variant. Additionally, this paper investigates the FDC in different distances. It can be found that the FDC shows little dependence on the distance at low frequencies, and the FDC in different distances shows a normal distribution. The results indicate that the FDC is not influenced by environments and distances in the UMa scenario under the NLOS case.

One-Legged (Single Limb) Stance Test
The One-Legged Stance Test (OLST)1,2 is a simple, easy and effective method to screen for balance impairments in the older adult population.
You may be asking yourself, "how can standing on one leg provide you with any information about balance, after all, we do not go around for extended periods of time standing on one leg?"
True, as a rule we are a dynamic people, always moving, our world always in motion, but there are instances were we do need to maintain single limb support. The most obvious times are when we are performing our everyday functional activities.
Stepping into a bath tub or up onto a curb would be difficult, if not impossible to do without the ability to maintain single limb support for a given amount of time. The ability to switch from twoto one-leg standing is required to perform turns, climb stairs and dress.
As we know, the gait cycle requires a certain amount of single limb support in order to be able to progress ourselves along in a normal pattern. When the dynamics of the cycle are disrupted, loss of balance leading to falls may occur.
This is especially true in older individuals whose gait cycle is altered due to normal and potentially abnormal changes that occur as a result of aging.
The One-Legged Stance Test measures postural stability (i.e., balance) and is more difficult to perform due to the narrow base of support required to do the test. Along with five other tests of balance and mobility, reliability of the One-Legged Stance Test was examined for 45 healthy females 55 to 71 years old and found to have "good" intraclass correlations coefficients (ICC range =.95 to.099). Within raters ICC ranged from 0.73 to 0.93.3
To perform the test, the patient is instructed to stand on one leg without support of the upper extremities or bracing of the unweighted leg against the stance leg. The patient begins the test with the eyes open, practicing once or twice on each side with his gaze fixed straight ahead.
The patient is then instructed to close his eyes and maintain balance for up to 30 seconds.1
The number of seconds that the patient/client is able to maintain this position is recorded. Termination or a fail test is recorded if 1) the foot touches the support leg; 2) hopping occurs; 3) the foot touches the floor, or 4) the arms touch something for support.
Normal ranges with eyes open are: 60-69 yrs/22.5 ± 8.6s, 70-79 yrs/14.2 ± 9.3s. Normal ranges for eyes closed are: 60-69 yrs/10.2 ± 8.6s, 70-79 yrs/4.3 ± 3.0s.4 Briggs and colleagues reported balance times on the One-Legged Stance Test in females age 60 to 86 years for dominant and nondominant legs.
Given the results of this data, there appears to be some difference in whether individuals use their dominant versus their nondominant leg in the youngest and oldest age groups.
When using this test, having patients choose what leg they would like to stand on would be appropriate as you want to record their "best" performance.
It has been reported in the literature that individuals increase their chances of sustaining an injury due to a fall by two times if they are unable to perform a One-Legged Stance Test for five seconds.5 Other studies utilizing the One-Legged Stance Test have been conducted in older adults to assess static balance after strength training,6 performance of activities of daily living and platform sway tests.7
Interestingly, subscales of other balance measures such as the Tinetti Performance Oriented Mobility Assessment8 and Berg Balance Scale9 utilize unsupported single limb stance times of 10 seconds and 5 seconds respectively, for older individuals to be considered to have "normal" balance.
Thirty percent to 60 percent of community-dwelling elderly individuals fall each year, with many experiencing multiple falls.10 Because falls are the leading cause of injury-related deaths in older adults and a significant cause of disability in this population, prevention of falls and subsequent injuries is a worthwhile endeavor.11
The One-Legged Stance Test can be used as a quick, reliable and easy way for clinicians to screen their patients/clients for fall risks and is easily incorporated into a comprehensive functional evaluation for older adults.

APTA Encouraged by Cap Exceptions
New process grants automatic exceptions to beneficiaries needing care the most
Calling it "a good first step toward ensuring that Medicare beneficiaries continue to have coverage for the physical therapy they need," Ben F Massey, Jr, PT, MA, president of the American Physical Therapy Association (APTA), expressed optimism that the new exceptions process will allow a significant number of Medicare patients to receive services exceeding the $1,740 annual financial cap on Medicare therapy coverage. The new procedure, authorized by Congress in the recently enacted Deficit Reduction Act (PL 109-171), will be available to Medicare beneficiaries on March 13 under rules released this week by the Centers for Medicare and Medicaid Services (CMS).
"APTA is encouraged by the new therapy cap exceptions process," Massey said. "CMS has made a good effort to ensure that Medicare beneficiaries who need the most care are not harmed by an arbitrary cap."
As APTA recommended, the process includes automatic exceptions and also grants exceptions to beneficiaries who are receiving both physical therapy and speech language pathology (the services are currently combined under one $1,740 cap).
"We have yet to see how well Medicare contractors will be able to implement and apply this process. Even if it works well, Congress only authorized this new process through 2006. Congress must address this issue again this year, and we are confident that this experience will demonstrate to legislators that they must completely repeal the caps and provide a more permanent solution for Medicare beneficiaries needing physical therapy," Massey continued.
The therapy caps went into effect on Jan. 1, 2006, limiting Medicare coverage on outpatient rehabilitation services to $1,740 for physical therapy and speech therapy combined and $1,740 for occupational therapy.
The American Physical Therapy Association is a national professional organization representing more than 65,000 members. Its goal is to foster advancements in physical therapy practice, research and education.

Hi can you help?
BUS 206 Milestone Two Guidelines and Rubric Overview: Business law impacts our everyday lives, both personally and professionally. Businesses enter contracts, manufacture goods, s ell services and products, and engage in employment and labor practices — activities that must all adhere to certain laws and regulat ions. Recognizing and evaluating legal issues is a fundamental skill that will help you navigate commercial relationships and avoid potential problems in the business world. Prompt: Imagine yourself as a paralegal working in a law office that has been tasked with reviewing three current cases. You will review the case studies and compose a short report for each, applying your legal knowledge and understanding of the types of business organizations. In each of the three reports, you will focus on areas of law covered in this course. Case Study Two concentrates on contracts and landlord – tenant law. Case Study Two : Sam Stevens lives in an apartment building where he has been working on his new invention, a machine that plays the sound of a barking dog to scare off potential intruders. A national chain store that sells safety products want s to sell Sam ' s product exclusively. Although Sam and the chain store never signed a contract, Sam verbally told a store manager several months ago that he would ship 1,000 u nits. Sam comes home from work one day and finds two letters in his mailbox. One is an eviction notice from his landlord, Quinn, telling him he ha s to be out of the apartment in 30 days because his barking device has been bothering the other tenants. It also state s that Sam was not allowed to conduct a business from his apartment. Sam is angry because he specifically told Quinn that he was working on a ne w invention, and Quinn had wished him luck. The second letter is from the chain store, demanding that Sam deliver the promised 1,000 units immediately. Specifically, the following critical elements must be addressed: A. Analyze the elements of this case to determine whether a valid contract exists between Sam and the ch ain store. Support your response by identifying the elements of a valid contract in your analysis. B. Assume there is not a valid contract between Sam and the chain store. Analyze the elements of a quasi – contract and a promissory estoppel to determine whethe r the chain store would prevail on a claim of either. Why or why not? Include support for your analysis. C. Identify the rights and obligations of both the landlord and tenant under a standard residential lease agreement. D. Based upon those rights and obligations, does Sam 's landlord have grounds to evict? Why or why not? E. Further, what defenses might Sam raise to an eviction action? Support your response. Guidelines for Submission: Your submission should be a one – to two – page Word document with double spacing, 12 – point Times New Roman font, and one – inch margins. Citations should be formatted according to APA style.

The platform measures 15.7 inches long by 9.8 inches wide and has a textured, non-slip surface. It's designed with a sturdy steel frame that has rubber padding underneath to prevent it from causing damage to floors.
The Advantages of Owning the Best Foot Rest
For an ideal posture while typing on a computer, users should have their wrists parallel to the floor and their spines straight. Knees should be bent at a 90-degree angle. If, when in this position, the feet aren't firmly planted on the floor, a foot rest can help to prop them up. Foot rests have a number of advantages, including:
 - Increasing blood circulation
 - Encouraging better posture
 - Preventing varicose veins and swelling
 - Preventing muscle atrophy
 - Encouraging active sitting
FAQs About Foot Rests
If you still have questions about how to choose the best foot rest, the answers to the following frequently asked questions may help.
Q. What is an ergonomic foot rest?
An ergonomic foot rest improves posture by allowing you to sit with your feet firmly planted with your knees at a 90-degree angle.
Q. How do I choose a foot rest?
Look for an adjustable foot rest made from durable materials that have non-slip padding on the bottom.
Q. How do you use a foot rest?
A foot rest is simply placed under your desk, allowing you to rest your feet on its surface. There's no need to remain in the same position all day long. Feel free to shift and readjust to whatever position feels comfortable.


How Well Do You Actually Know the Fizz?
One of the original hangover cures, the fizz has gone through countless iterations since its first recorded mention in the 1860s. Here, get to know the fizz in five classic recipes and their modern interpretations.
Before the Bloody Mary became the universal morning-after prescription, the fizz, a sour made tall by the addition of soda water and the optional egg white, was for half a century the perfect hair-of-the-dog remedy.
First recorded in print in 1867 by Jerry Thomas as simply lemon, sweetener, spirit and seltzer, this corpse reviver began its ascendancy towards cocktail celebrity alongside the daisy and the Collins, bearing a strikingly close resemblance to the latter and differing only in preparation (shaken versus built in the glass) and manner of consumption (hurriedly versus steadily).
By 1890 the fizz had attracted a dedicated following, most notably by the self-proclaimed "champion gin fizz drinker in America," Professor Denton of Brooklyn, New York, known for his preternatural capacity to consume 40 fizzes in any given day. According to David Wondrich's Imbibe!, so voracious was his appetite for fizzes that Denton once even tried to consume the glass, only to subsequently—and unsurprisingly—die from internal hemorrhaging.
Though other notable fizzes emerged in the 19th century (among them, the Silver Fizz and the Morning Glory Fizz, both of which see the addition of egg white), the Ramos Gin Fizz remains the most famous iteration. Invented in 1888 by Henry Charles Ramos of New Orleans' Imperial Cabinet saloon, the citrus—in this case, a double dose of lemon and lime—is supplemented with two frothy thickeners: both cream and egg white. Requiring a significant amount of emulsifying, the namesake fizz famously called for a line of shakermen, men ready to pass the shaker along, each shaking for part of the full 12 minutes required to properly make the drink. (Nowadays, that overt inefficiency has led some bartenders to hack the process with bubble tea machines and hand held blenders.)
As a category, this "long drink par excellence," as one San Francisco bartender described it, had, within the first few decades of its existence, won widespread appeal, spurring countless variations based on nearly every available spirit. Ultimately, it became so ubiquitous that in 1941, Crosby Gaige, author of his eponymous cocktail guide and ladies companion declared that the fizz and its long-drink ilk had, "like great danes and greyhounds... finally become family pets." Here, three classic fizzes stand alongside their modern counterparts:
Original: Gin Fizz
Modern: Corenwyn Clipper
With gin, simple syrup and citrus at its base, the classic Gin Fizz has an assertive kick from spirit and is notably served in a highball—without ice. In a play on the original, Eben Freeman shakes together malty genever, lemon and crème de mûre before straining it all into a couple, and topping not with soda water, but with sparkling wine.
Original: Ramos Gin Fizz
Modern: Brandy LiftDanger Zone
The milkshake of fizz drinks, the Ramos Gin Fizz is also the most time-consuming; thanks to the addition of both egg white and cream, it famously required a full 12 minutes of shaking to achieve the desired consistency. A modern version, the Brandy Lift, forgoes the egg but keeps the cream and spirits (brandy and Bénédictine), for a drink that, when shaken with orgeat and topped with soda water, straddles the line between a fizz and a milk punch. The similarly textured Danger Zone meanwhile gets its creamy texture from the addition of a whole egg.
Original: Gin Fizz TropicalMorning Glory FizzSeapea Fizz
Modern: High Line Fizz, Mid-Morning Fizz, Sloe Gin FizzLefty's Fizz
The most iconic template for today's fizz is notable for its inclusion of both soda water and egg white—and not cream. And while some are gin-based (like the Gin Fizz Tropical, not to mention its modern iterations, the High Line Fizz, the Mid-Morning Fizz and the Sloe Gin Fizz, which see the additions of dry Curaçao, green Chartreuse and Sloe Gin, respectively), the template for the classic fizz has been known to include a wide variety of spirits; the Morning Glory Fizz, invented in the late 1800s, is Scotch-based, while the Seapea Fizz, which dates to 1934, calls on absinthe. In a truly modern variation, the Lefty's Fizz from San Francisco's ABV opts for mezcal and grapefruit shrub for a smoky, sour play on the original.

Results Follow Up, UNAD 2017
The project "Digitalizing Uganda Sign Language" aims to make Uganda sign language accessible via digital platforms.
There is no digital resource available to learn Uganda sign language today.
Spider supports the implementation and research for the project "Digitalizing Uganda Sign Language". The project is based in Uganda and aims to make Uganda sign language accessible via digital platforms across the country. The Spider results follow up performed a baseline study at the beginning of the project to examine the level of ICT use and accessibility for sign language in Uganda's various regions. This will help UNAD understand stakeholders' experiences, expectations and the challenges in utilising Uganda's digital sign-language content.
The baseline study on use of ICTs for learning sign language in Uganda shows that mobile apps, social media networks and CDs are very helpful in learning sign language.
The baseline study on use of ICTs for learning sign language in Uganda shows that mobile apps, social media networks and CDs are very helpful in learning sign language. Findings show that there are low levels of ICT use and accessibility among sign language learners in the different regions of Uganda. Yet the attitude towards using ICTs to learn sign language is positive, among the deaf, their friends, sign language instructors, parents and community service providers (such as nurses, the police, teachers, business persons, etc.).
Social media groups, videos on WhatApps and Facebook, mobile apps and compact discs (CDs) were among some of the commonly used ICTs for learning sign language.
The baseline study found that challenges related to use of these ICTs include unaffordable costs for Internet especially when learners have to share and download videos and also acquiring the artefacts (smartphones, CDs, etc.).
The Channel 4 Documentary "Patrick Speaks" shows how 15 year Patrick Otema learns sign language and how this knowledge breaks the silence he has lived in so far.
Literacy among deaf persons was found to be low. A majority of them have only primary school education. Most schools offer no special education beyond primary level. Literacy challenges also make it difficult to use ICTs as well as other learning materials such as dictionaries and tutorials.
The baseline study highlights some of the interventions to address challenges faced by deaf people and sign language learners in Uganda. The Ugandan population has to be sensitised on how to communicate with the deaf rather than stereotyping them as social misfits. To achieve this, the study recommends creating awareness programmes and integrating sign language learning into national education programmes.
Literacy challenges also make it difficult to use ICTs as well as learning materials such as dictionaries and tutorials.
There is a need to borrow a leaf from universal sign language programmes but also to contextualise particular interventions, especially the curriculum and content developed. Some of the signs are not universal and for this reason the signs confuse learners. Therefore, learning materials should address content localisation issues.
When it comes to learning sign language using ICTs, the study found that there is a need to streamline strategies for digital sign language implementation. For example availing digital resources (content, devices, etc.) to the deaf and their helpers and empowering people and institutions which were found to be influential in supporting the deaf: that is, friends, religious institutions, family members and deaf instructors. These would scale the cause.


Airborne Detector for Energetic Lightning Emissions (ADELE)
Operated By:
The Airborne Detector for Energetic Lightning Emissions (ADELE) detects gamma-rays and relativistic electrons associated with lightning and thunderstorm charging. The primary scientific target is terrestrial gamma-ray flashes (TGFs), brief (< 1 millisecond), extremely bright bursts of high energy radiation that have mostly been detected from satellites in low Earth orbit. TGFs are usually simultaneous with intra-cloud lightning, but only a small fraction of these lightning flashes seem to produce them. The cause of TGFs, their connection with lightning, and whether they are frequent enough to be a radiation hazard to airline passengers and crew are all unanswered questions.
ADELE is designed to study these events from close to their production site, where the signal can be much more intense than it is for the satellites 600 km away from the storm. On the AV-1 Globak Hawk in HS3, ADELE will pass above and near electrified storms in both the eyewall and rainband regions. ADELE uses three scintillation detectors -- 5" and 1" diameter plastic scintillators and a 3" diameter lanthanum bromide scintillator. The plastic detectors provide the ability to measure extremely high count rates without saturation, and the lanthanum bromide detector provides improved spectroscopic information on the energy distribution of the gamma rays. All three detectors are enclosed in a single box in the interior of the Global Hawk, since the gamma radiation (100 keV up to about 50 MeV) is highly penetrating.

Set the background color of a Power BI Embedded IFrame
Date de publication : 01 juin, 2018
When the IFrame size that's allocated for an embedded object and the embedded object itself don't share the same aspect ratio, the result is gray margins on the sides (marked in red in the following figure).
Grey Shoulders
You can use the Custom Layout API to define how to fill the IFrame or set a fixed size for the object at any time. But that sometimes doesn't entirely fix the appearance of the gray margins.
You can now set the background color of the IFrame by making it transparent. By doing so, you'll give the IFrame the defined color of the DIV element that contains the IFrame. You have full control of what color/background layout will be seen in the margins, making the embedded object wrapped entirely by the application design.
Note that the default color is still gray, so you'll need to set a definition in the JavaScript code to get the transparency of the IFrame.

Study promoter activity using the Living Colors Fluorescent Timer, a fluorescent protein that shifts color from green to red over time (1). This color change provides a way to visualize the time frame of promoter activity, indicating where in an organism the promoter is active and also when it becomes inactive. Easily detect the red and green emissions indicating promoter activity with fluorescence microscopy or flow cytometry.
Easily Characterize Promoter Activity
The Fluorescent Timer is a mutant form of the DsRed fluorescent reporter, containing two amino acid substitutions which increase its fluorescence intensity and endow it with a distinct spectral property: as the Fluorescent Timer matures, it changes color—in a matter of hours, depending on the expression system used. Shortly after its synthesis, the Fluorescent Timer begins emitting green fluorescence but as time passes, the fluorophore undergoes additional changes that shift its fluorescence to longer wavelengths. When fully matured the protein is bright red. The protein's color shift can be used to follow the on and off phases of gene expression (e.g., during embryogenesis and cell differentiation).
Fluorescent Timer under the control of the heat shock promoter hsp16-41 in a transgenic C. elegans embryo. The embryo was heat-shocked in a 33°C water bath. Promoter activity was studied during the heat shock recovery period. Green fluorescence was observed in the embryo as early as two hr into the recovery period. By 50 hr after heat shock, promoter activity had ceased, as indicated by the lack of green color.
pTimer (left) is primarily intended to serve as a convenient source of the Fluorescent Timer cDNA. Use pTimer-1 (right) to monitor transcription from different promoters and promoter/ enhancer combinations inserted into the MCS located upstream of the Fluorescent Timer coding sequence. Without the addition of a functional promoter, this vector will not express the Fluorescent Timer.
Detecting Timer Fluorescent Protein
You can detect the Fluorescent Timer with the DsRed Polyclonal Antibody.
You can use the DsRed1-C Sequencing Primer to sequence wild-type DsRed1 C-terminal gene fusions, including Timer fusions.

Background: Phosphatidylinositol transfer protein (PI-TP), which has the ability to transfer phosphatidylinositol (PI) from one membrane compartment to another, is required in the inositol lipid signalling pathway through phospholipase C-beta (PLC-beta) that is regulated by GTP-binding protein(s) in response to extracellular signals. Here, we test the hypothesis that the principal role of PI-TP is to couple sites of lipid hydrolysis to sites of synthesis, and so to replenish depleted substrate for PLC-beta.
Results: We have designed an experimental protocol that takes advantage of the different rates of release of endogenous PI-TP and PLC-beta from HL60 cells permeabilized with streptolysin O. We have examined the kinetics of stimulated inositol lipid hydrolysis in cells depleted of PI-TP, but not of endogenous PLC-beta, in the presence and absence of exogenous PI-TP. Linear time-courses were observed in the absence of any added protein, and the rate was accelerated by PI-TP using either guanosine 5'[gamma-thio]-triphosphate (GTP gamma S) or the receptor-directed agonist fMetLeuPhe as activators. In addition, depletion from the cells of both PI-TP and PLC-beta isoforms by extended permeabilization (40 minutes) allowed us to control the levels of PLC-beta present in the cells. Once again, PI-TP increased the rates of reactions. To identify whether the role of PI-TP was to make available the substrate phosphatidylinositol bisphosphate (PIP2) for the PLC, we examined the synthesis of PIP2 in cells depleted of PI-TP. We found that PI-TP was essential for the synthesis of PIP2.
Conclusions: The predicted function of PI-TP in inositol lipid signalling is the provision of substrate for PLC-beta from intracellular sites where PI is synthesized. We propose that PI-TP is in fact a co-factor in inositol lipid signalling and acts by interacting with the inositol lipid kinases. We hypothesize that the preferred substrate for PLC-beta is not the lipid that is resident in the membrane but that provided through PI-TP.

KANCHANPUR: Number of Siberian bird in the watersheds of Shuklaphanta Wildlife Reserve has deceased lately, officials and locals said.
The birds from Siberia arrive in the watersheds of Shuklaphanta Wildlife Reserve every year in search of warm habitat after the watersheds in the northern poles were covered with snow.
The Siberian birds return to their original habitats, thanks to lack of water and foods, and rise in temperature in the Shuklaphanta Wildlife Reserve.
Basically, the Siberian birds roam and collect their food around Ranital, Kalikich, Salgaudi, Sikarital, Pyaratal, Jhimlatal and other areas of the Reserve.
According to Reserve, more than 300 species of Siberian birds arrive here every year.

Nightfall Summary
In 1941, John W. Campbell, Jr., editor of the premier science fiction magazine at that time, asked one of the fledgling writers he mentored an intriguing question: What would happen if people saw the stars only once every thousand years? He postulated that people would go mad and asked twenty one-year old Isaac Asimov to write a story about it. The result was "Nightfall," now one of the most famous science fiction stories of all...

Sunburn and Eye Pain or Vision Problems
Sunburn and Eye Pain or Vision Problems
Eye pain or vision problems after being in the sun can be serious.
Symptoms of vision problems from sun exposure may include:
 - Partial or complete vision loss.
 - Burning pain.
 - A feeling that something is in your eye (foreign body sensation).
 - Decreased vision.
 - Photophobia.
The eyes are very sensitive to sunlight. Sunburning your eyes can cause damage to the light-sensitive membrane that covers the inside of the eyeball (retina) or damage to the lens (which can eventually cause cataracts).
You might also have pain, more tearing, and a gritty feeling in your eyes if they have been sunburned. These symptoms usually begin several hours after being in the sun. If these symptoms do not go away, an evaluation by a doctor is needed.
Snow blindness is a sunburn of the clear covering over the colored part of the eye (cornea). Snow blindness occurs at high altitudes where the sunlight is more intense. Skiers, climbers, and hikers should wear protective sunglasses with side panels to reduce the amount of ultraviolet (UV) rays reflected into the eyes.
Damage to the retina is usually the result of having looked directly at the sun. The intense brightness of the sun stops most people from looking directly at it. Looking at a solar eclipse without protective eyewear can also cause eye damage. Problems with the retina can lead to impaired vision or blindness.
Cataracts can be caused from direct, intense ultraviolet rays hitting the eyes over many years. Cataracts are one of the leading causes of blindness. Cataracts develop gradually over a long time.
Sunglasses that block 99% or 100% of ultraviolet rays can protect you from eye problems related to sun exposure. Sunglass labels that say UV absorption up to 400 nanometers (nm) provide 100% UV protection.

Yes this is quite possible take a look at the "MotionDetection" example provided with EMGU this should get you started.
Effectively the code that removes the foreground is effectively named "_forgroundDetector" it is the "_motionHistory" that presents stores what movement has occurred.
The example has everything you need if you have trouble running it let me know,

Bottle uses a powerful routing engine to find the right callback for each request. The tutorial shows you the basics. This document covers advanced techniques and rule mechanics in detail.
Router distinguishes between two basic types of routes: static routes (e.g.
/contact) and dynamic routes (e.g.
/hello/). A route that contains one or more wildcards it is considered dynamic. All other routes are static.
Changed in version 0.10.
The simplest form of a wildcard consists of a name enclosed in angle brackets (e.g.
). The name should be unique for a given route and form a valid python identifier (alphanumeric, starting with a letter). This is because wildcards are used as keyword arguments for the request callback later.
Each wildcard matches one or more characters, but stops at the first slash (
/). This equals a regular expression of
[^/]+ and ensures that only one path segment is matched and routes with more than one wildcard stay unambiguous.
// matches as follows:
You can change the exact behaviour in many ways using filters. This is described in the next section.
New in version 0.10.
Filters are used to define more specific wildcards, and/or transform the matched part of the URL before it is passed to the callback. A filtered wildcard is declared as
. The syntax for the optional config part depends on the filter used.
The following standard filters are implemented:
- :int matches (signed) digits and converts the value to integer.
- :float similar to :int but for decimal numbers.
- :path matches all characters including the slash character in a non-greedy way and may be used to match more than one path segment.
- :re[:exp] allows you to specify a custom regular expression in the config field. The matched value is not modified.
You can add your own filters to the router. All you need is a function that returns three elements: A regular expression string, a callable to convert the URL fragment to a python value, and a callable that does the opposite. The filter function is called with the configuration string as the only parameter and may parse it as needed:
app = Bottle() def list_filter(config): ''' Matches a comma separated list of numbers. ''' delimiter = config or ',' regexp = r'\d+(%s\d)*' % re.escape(delimiter) def to_python(match): return map(int, match.split(delimiter)) def to_url(numbers): return delimiter.join(map(str, numbers)) return regexp, to_python, to_url app.router.add_filter('list', list_filter) _USER_.route('/follow/') def follow_users(ids): for id in ids:...
Changed in version 0.10.
The new rule syntax was introduce in Bottle 0.10 to simplify some common use cases, but the old syntax still works and you can find lot code examples still using it. The differences are best described by example:
|Old Syntax||New Syntax|
Try to avoid the old syntax in future projects if you can. It is not currently deprecated, but will be eventually.
Explicit routing configuration¶
Route decorator can also be directly called as method. This way provides flexibility in complex setups, allowing you to directly control, when and how routing configuration done.
Here is a basic example of explicit routing configuration for default bottle application:
def setup_routing(): bottle.route('/', 'GET', index) bottle.route('/edit', ['GET', 'POST'], edit)
In fact, any
Bottle instance routing can be configured same way:
def setup_routing(app): app.route('/new', ['GET', 'POST'], form_new) app.route('/edit', ['GET', 'POST'], form_edit) app = Bottle() setup_routing(app)
