 Trivia questions : What is Blood Warmer？
 Blood warmer
 Blood warmer is a specific type of fluid warmer. There are two main types of liquid heaters: one is a device (usually a heating cabinet) that heats the liquid before use; the other is a device that actively heats the liquid when in use, that is, pipe heating.
 Blood warmer use
 Blood warmers are used to heat blood or other fluids to minimize the risk of hypothermia. The blood is refrigerated to preserve the cells. During the blood warmer transfusion process, it must be heated to a suitable temperature, not only to prevent hypothermia, but also to prevent hemolysis or blood cell rupture.
 All patients who require significant resuscitation and resuscitation of blood products must use a liquid heater to prevent serious complications from hypothermia.
 Due to its small size, it is mainly used in pet surgery, such as dogs and cats, especially dogs. In many countries, this product is used exclusively in dog surgery and has received wide acclaim.
 The role of blood warmer
 Liquid heater to avoid causing hypothermia and its harmful effects.
 Hypothermia can lead to the acceleration of all physiological functions, including cardiovascular and respiratory system, nerve conduction, mental acuity, neuromuscular reaction time and metabolic rate. In young children, the low temperature caused by immersing the whole body in water close to freezing can protect the brain during hypoxia.
 Decreased core body temperature can lead to apathetic drowsiness, clumsy hands and feet, confusion, irritability, illusoryness, slowed or stopped breathing, slowed heartbeat, irregularities, and finally stopped. But as long as the patient is not warm, the patient should not be considered dead. A rectal temperature of <34 °C helps to distinguish it from similar symptoms due to heart disease, diabetic coma, insulin overdose, cerebrovascular accident, or drug abuse. Ordinary clinical thermometers cannot measure very low body temperature when the body temperature is too low. A special hypothermia meter must be used. If there is only a standard clinical thermometer, the mercury column cannot rise above 34 °C to indicate that the body temperature is too low.
 How does a blood warmer work?
 As the equipment passes through the pipeline, the blood warmer device heats the pipeline and fluid. Designed perfusion volume, flow rate, portability, and distance to the patient vary. The greater the distance between the device and the patient, the better the fluid will cool before it reaches the patient.
 About pet surgery
 With more and more people now having pets, cats and dogs, it is inevitable that when pets are raised, pets will be ill and need surgery. Under what circumstances will pet surgery be needed? Sometimes, for example, when pet surgery is necessary because of a pet's illness.
 Dog surgery
 Compared to cats, there may be more dog owners, and dogs are inherently more mobile than cats, and they are naturally more likely to be injured than cats. And dog diseases often occur, and serious diseases often require surgery to cure. Therefore, dogs are often seen in veterinary hospitals undergoing surgery.
 Cat surgery
 Like dogs, cats can also be injured and sick, but cats are smaller than dogs, so it is unlikely that a blood heater will be used during cat surgery, but it can also be used in particularly severe cases.

Camellia sinensis is the species of plant whose leaves and leaf buds are used to produce tea. It is of the genus Camellia, a genus of flowering plants in the family Theaceae. White tea, green tea, oolong, pu-erh tea and black tea are all harvested from this species, but are processed differently to attain different levels of oxidation. Kukicha (twig tea) is also harvested from Camellia sinensis, but uses twigs and stems rather than leaves. Common names include tea plant, tea tree, and tea shrub. There are two major varieties that characterize this species (1) Camellia sinensis var. sinensis (L.) Kuntz and (2) Camellia sinensis var. assamica (Masters) Kitam.

Social Loafing
Definition: Social Loafing is in psychology and sociology regarded as the tendency of individuals to reduce efforts when working on a collective task (i.e., when outputs are pooled with those of other group members) as compared to when the individual works alone. It happens because all members of the group are combining their efforts to reach a common goal. The group members tend to contribute less than what they would if they had to do a task alone.
The phenomenon is regarded as one of the main reasons groups are often less productive than the combined performance of their members working as individuals.

matter versus non-matter:
This term, 'Matter versus Non-Matter', refers to the basic distinction between Corporeality (Matter!) and Incorporeality (Non-Matter!) Matter is the Known World, on this side of the Fence, while Non-Matter is the Unknown 'World', on 'the other side' of that invisible Fence between Reality and 'Reality', or between Differentiated Relativity and Undifferentiated Relativity!
Matter and the Known, is all that is physical, material and visible, including the human Brain and Body. Non-Matter and the Unknown, is all that is non-physical/material, invisible and Spirit, which includes the human Mind and Consciousness, as well as Infinite Consciousness (God)!

How to make an object that handles multiple collision zones by using multiple sub-objects
I used this technique in my recent Ludum Dare game, Ancient Technologies. The project has a TON of extraneous code in it, some of which is pretty messy, so I'll replace the download link with a cleaner example project of just this technique in coming days.
If you look at the Atari 2600 console in this game, it is actually multiple objects, made to look like a single object. This enables each switch to have its own collision detection and mouse events.
I accomplished this with a few simple techniques that work really well:
The console itself is the main object. Then there are 6 objects for the 6 switches on the console.
I then took the image I wanted to use for the sprite, and cut out all the different clickable regions, putting each into its own subimage by itself. Then once all the subimages were created, I removed each subimage into its own sprite, and set the collision mask to cover just the pixels in the image
As you can see, this approach results in a lot of "wasted" space in the sprite sheet in the form of transparent pixels, but if you're concerned about this, you could always achieve the same effect by using sprite origin and sprite offset to position the images without all the whitespace in the sprite sheet. I skipped using sprite origin because I didn't feel like bothering with counting pixels and setting each sprite origin differently. That would have been tedious, and if I had ever needed to change the sprites, could have thrown everything off and required extensive rework to recalculate again. If your sprites are tiny, it probably doesn't matter too much, but if they're quite large, then you should probably use sprite origin/offset.
(Note: With the small pieces, you'd need to use origin numbers that are larger than the dimensions of the sprite itself, or possibly negative values for the origin. You'd also need to carefully calculate the distance to set the origin so that the images all line up precisely. The goal is to make all the images align when each instance's x and y are identical. This makes them easy to move around together as a group, without having to deal with offsets and so on. To make everything align easy, I created sprites that have the same height and width, so that getting them to align takes no extra effort or calculation at all.)
Next, use the "main" object to generate the collision zone objects, in the create event:
Note the example code below isn't exactly the code in my project, but is cleaned up a bit for easier comprehension.
///oConsole Create Event: power_switch = instance_create(x, y, oPowerSwitch); tv_type_switch = instance_create(x, y, oTVTypeSwitch); left_difficulty_switch = instance_create(x, y, oLeftDifficultySwitch); right_difficulty_switch = instance_create(x, y, oRightDifficultySwitch); select_switch = instance_create(x, y, oSelectSwitch); reset_switch = instance_create(x, y, oResetSwitch);
Since these objects all use sprites that are the same size, they all line up together when their x,y position is the same. Now you have an easy way to place just the main object and have it create all of its collision zone objects, perfectly aligned.
If the main object needs to be able to move, you just need to update the x,y of all the objects whenever you need to.
Another great thing is that each of these instances can have its own animation which is completely separate from the rest of the collection of objects. This means you can do really sophisticated animation rigging.
Also, you can access the instance variables of the collision instances by using the main instance, like so:
oConsole.power_switch.position = UP;
is (essentially) equivalent to:
oPowerSwitch.position = UP;
This allows you to use the collision zone instances' instance variables like you would use properties of a helper class in another language, which may make accessing these variables easier if you're used to other programming languages.
As well, if each of these switch instances were of the same object, using the
id returned by
instance_create() would allow you to differentiate between them. This could be useful for, say, a battleship with multiple turrets that are all of the same object type.
Finally, you'll want to be mindful that if you destroy the main object, you'll likely want to destroy all the sub-objects. Perhaps not — maybe you're doing a spaceship with an escape pod or a rocket with multiple stages that break away. But in that case you'll wan to be sure that once the main object is gone, you are handling whatever remains somehow.

You've seen plenty of movies and TV shows where a person hyperventilates and is given a paper bag to breathe into. Can wood pulp actually help with hyperventilation? And why do so many doctors want the practice to stop?
The paper bag as a medical device features in everything from old Looney Toons cartoons to big budget movies (albeit mostly romantic comedies). Why are people who start hyperventilating given someone's lunch bag to breathe into? That won't give them the oxygen they need.
And the people do need oxygen. There isn't enough of it getting to their tissues. Unfortunately, hyperventilation isn't going to help. Breathing with too much rapidity is one of those unfortunate responses that seems to short-circuit the body's survival instincts. A person who is hyperventilating has plenty of oxygen in their blood, but it isn't making it to where it needs to go. Blood doesn't just carry oxygen, it carries carbon dioxide, and it needs to carry carbon dioxide. The body responds to the amount of carbon dioxide in the blood. Too little carbon dioxide causes two things to happen. First, there is vasoconstriction, the narrowing of the blood vessels, which chokes off a blood supply to the extremities of the body.
Secondly, there is the matter of blood pH. As it carbon dioxide levels go up, the pH of blood goes down towards the acid end of the pH scale. This stimulates the hemoglobin to release oxygen into the tissues. As carbon dioxide levels go down - as they do when the person hyperventilates - blood pH heads up towards the base end of the scale. This causes the hemoglobin to hang on to its oxygen. So even when blood gets through constricted vessels, it can't deliver as much oxygen to tissues.
The person feels like they're smothering, which they are, and hyperventilates in an attempt to get more oxygen. This decreases the carbon dioxide in their blood even more, and exacerbates the problem. The best way to stop it is to shove a barrier between the sufferer and the open air. By forcing them to rebreathe their exhaled carbon dioxide, it's possible to increase carbon dioxide levels in their blood, and deliver more oxygen to tissues. The paper bag, low-tech as it is, actually does help.
Many doctors, however, are asking that people stop using it. It's not that it's ineffective in treating pure hyperventilation. The problem is, a lot of things trigger hyperventilation. While someone who is panicking can be helped by upping the level of carbon dioxide in their blood, someone who is having a heart attack, or an asthma attack, might be killed by an increase of carbon dioxide. Without knowing the exact cause of the hyperventilation, it can be dangerous to treat it. Perhaps it's better just to hyperventilate for a while — and call a doctor if it doesn't stop.

committed to reducing their carbon footprint will find paperless solutions align perfectly with their environmental goals, simultaneously streamlining workflow and conserving resources.
On the other hand, opting not to purchase paperless board meeting software could be a deliberate choice for organizations with a minimal meeting schedule or those operating within tight budget constraints where the cost-benefit analysis does not justify the investment. Additionally, companies with a board that prefers traditional, tactile interaction with physical documents, or those operating in regions with unreliable internet access, may find that paperless solutions offer more challenges than conveniences, making the investment impractical at the current juncture.
Mostly, Paperless Board Meeting Software offers end-to-end solutions for board meeting management. This includes features such as meeting scheduling, automatic reminders, document digitization, real-time collaboration, annotation and discussion tools, voting & approval mechanisms, and meeting minutes generation.
Security is a primary concern for these types of software due to the sensitive nature of board communications. Many Paperless Board Meeting software utilize advanced security protocols like encryption, two-factor authentication, and rigorous access controls to ensure confidentiality and data privacy.
Yes, most Paperless Board Meeting Software is designed to be device-agnostic, which means it can be accessed via varying devices such as laptops, tablets, and smartphones. Additionally, they also offer mobile apps for on-the-go access, providing easy access to board materials anywhere, anytime.
This software simplifies the meeting organizing procedure. You can schedule meetings, create agendas, and distribute materials electronically before the meeting. During the meeting, participants can take notes, discuss, vote, and so on directly within the software. Afterwards, the software can automatically generate meeting minutes and distribute them.
Advances in Paperless Board Meeting software can increase productivity and efficiency of board meetings, mitigate risk with high-level security features, and significantly reduce organization's environmental footprint. The software also allows for better compliance by providing a central location for keeping historical meeting data, easily accessible for auditing purposes.


Best Video Surveillance System for Winter Weather Theft
Posted by Amy Hite on November 29, 2017
Criminal activity and behavior change with the seasons. During the summer, crime against people rises. In the winter, there is an increased amount of reported property theft, which makes it more critical to have the best video surveillance system in place. Property theft can occur at shopping centers, medical office spaces, flex space properties, multfamily apartments, car dealerships and other types of commercial properties.
According to a study called The Influence of the Seasons of Crime Rate, there are several hypotheses as to why theft goes up during the winter season. One popular theory is that basic human needs increase due to the pressures of finding shelter and reliable transportation during the cold weather. This can lead to car theft, food theft, and other types of property theft.
A second hypothesis is based on the job market. Seasonal unemployment reaches its peak in the winter months. Heat, clothing, and electricity expenses are much higher during the winter and people may have more difficulty paying these bills. Thieves without a stable income may be motivated to commit burglary.
An article by AccuWeather cites a report by Atlanta Crime Stoppers. The report states that people leave their cars unattended while they warm them up during the winter. This gives thieves an opportunity to steal the car. To avoid theft, owners should stay near the car while it warms up. Car owners can use that time to scrape ice or snow off the car and make sure that tires are safe and inflated.
Daylight hours may impact the increase of reported winter weather theft. It gets darker earlier during the winter months and thieves generally use the cover of night to commit crimes. Also, fewer daylight hours mean there will not be as many people out and active and the potential for witnesses will decrease.
Protect Your Property With the Best Video Surveillance System
The best video surveillance system can help protect your property from theft and damage. The best video surveillance system is one that is watched, to effectively deter and reduce crime. Trained operators can look for unusual activity, activate a speaker alert, and call the local police. Stealth Monitoring can watch your existing security cameras or provide a full customized solution with high resolution cameras and live video monitoring.

PURPOSE: Pulmonary arterial hypertension (PAH) results in a progressive increase in pulmonary vascular resistance, right heart failure, and eventually death. Although current therapies for PAH improve functional status, quality of life, and in some cases survival, the high cost of these pharmacological therapies has been a concern. In this study, our goal is to perform a cost analysis of the current treatment of PAH and compare it with other accepted treatment options for various disease processes.
METHODS: We compared the average cost needed to prevent one death per year between diseases. This was obtained by multiplying the average treatment cost per year with the number needed to treat (NNT) to prevent mortality in one year. Mortality benefits were estimated by comparing survival data with a mortality formula derived form the National Institute of Health experience. Average wholesale prices (AWP) were obtained for pharmacological agents from inquiries of the pharmacy at Cleveland Clinic Florida. For procedural therapies, costs were obtained based on Medicare payments.
RESULTS: In the treatment of PAH, Bosentan cost was estimated at $406,000 per life saved, Epoprostenol cost was estimated at $968,000 per life saved, subcutaneous Treprostinil cost was estimated at $1,715,000 per life saved and inhaled Iloprost cost was estimated $873,000 per life saved. Mortality data of Sildenafil was not included in the analysis. Implantable automatic cardiac defibrillator costs $315,000 per life saved, left ventricular assist devices costs $654,968 per life saved, the treatment of follicular non-Hodgkin's lymphoma with Cyclophosphamide, Adriamycin, Vincristine, Prednisone and Rituximab costs $1,080,000 per life saved, pacemakers for atrial fibrillation costs $1,795,846 per life saved, and treatment of lupus nephritis with Mycophenolate mofetil costs $16,065,000 per life saved.
CONCLUSION: The cost of various pharmacological agents used to treat PAH are at an acceptable cost effectiveness range for pharmacotherapeutic and biotechnological interventions.
CLINICAL IMPLICATIONS: The PAH pharmacological agents are a reasonable treatment modality for this disease state.

Anthesis is the funeral service given by the people whose loved ones have passed away. They render all kinds of services like providing a van for the dead body transfer, crematorium services, arrangement of the funeral services, and also the priests. Anthyesti aims to allow the grieving families to do the last rituals for their loved ones.
What is the purpose of Funeral Services?
- It helps the grieving families acknowledge that their loved ones have died.
- It gives them the chance to say their last goodbyes.
- With the help of funerals, people can move on with their life, and it also offers continuity with a hope to keep on living their life.
- Funerals render the grieving family, friends, and community a support system to continue living.
- With the help of funerals, one can understand the meaning and depth of life and death.
Need for a memorial service –
- Pay tribute –
With the help of the memorial service, the families and friends can pay tribute to their loved ones. Among the many purposes, the service helps to realize death, reminds of the present life, and supports them to move on in the difficult phase of life.
- Begin mourning –
It helps the survivors acknowledge death, as it is the first step towards grief that is filled up inside, allowing us to mourn. Mourning can help relax and let go of all the pent-up emotions in an individual for their loved ones who have passed away.
- Receive support –
It allows the families and friends to portray their love and respect for the important people. Sometimes, just looking at how much other people care for their loved ones will comfort them and help them adjust for their loss.
- Helps to express the feelings –
For many years, beliefs, thoughts, and emotions can be expressed with the help of funerals. It allows one to acknowledge that their loved one has died and helps to say their last goodbyes.
Importance of the funeral ceremony rituals –
Rituals are important for family members and friends as it helps them express their deepest thoughts and feelings. It is also very symbolic for everyone because it helps them realize some of the most important events of their life.
What are the common factors among all the rituals?
- Rituals help unite with everyone through these events, and it also furnishes a support system for them to share their common beliefs and values.
- With the help of rituals, families and friends can feel at ease.
- Rituals help express the feelings through the beliefs and feelings when words cannot justify those. Not only objects but also the rituals help to symbolize a greater image.
Therefore, anthyesti can help grieving families, relatives, and friends relax and move on with their lives. With their services of transporting dead bodies, crematorium services, and many more, they can take the burden of doing all the rituals accordingly. Funeral rituals can help grieving members express their beliefs, thoughts, and feelings about their loved ones.

Beaker with Raptors
- western Iran
- 14th - 13th century B.C.
- H-12.1 D-7
The shape and proportions and even the reinforced rim of this beaker resemble those of the vessel discussed in catalogue number 21. This beaker is also made in two pieces, the cylindrical part and the bottom. The outside of the beaker is decorated with two rows of raptors, or birds of prey: Those in the upper register face toward the viewer's right, and those in the lower row, to our left. The forms are rendered in low relief, raised only slightly from the plain ground. Each bird has a hooked beak as well as a large, round eye, that is set amid a scale-like feather pattern, which covers its head, body, and upper legs; the square tail and the tapering wings are carefully rendered with long, slender feathers. Roughly crosshatched areas indicate the featherless lower legs. The species represented remains unidentified, but the short, curving beak and prominent round eye are more parrot-like than predatory. The surface of the bottom of the beaker is filled with a compass-drawn rosette, and is decorated with an overall pattern of circular punch marks.
These strutting birds find few parallels in Mesopotamian art of the later second millennium B.C., in which raptors generally are depicted in heraldically symmetrical compositions with domestic animals. Striding birds do occur, however, on a crushed-gold bowl excavated from Tomb 32 at Marlik in the southwestern region of the Caspian watershed.1 Our raptors share their stance and substantial proportions with the Marlik birds, which are more advanced technically, their heads worked in the round and turned outward toward the viewer. The Shumei beaker is rather simple and not so sophisticated and thus probably predates the Marlik bowl. Unfortunately, the fifty-three Marlik tombs, which have been dated from the fourteenth to the late eighth century B.C.,2 have as yet no secure sequence. Thus, the date of this beaker with birds is somewhat uncertain.

the efficiency of a particular synthesis technique. Our first guess was to use : SUM(k=1 to n) ((A2(t,k) - A1(t,k))^2 e(t) = sqrt( ------------------------------------ ) SUM(k=1 to n) A1(t,k)^2 which gives a normalized difference (error) vs. time. k is the partial number t is time, and A1(t,k) and A2(t,k) are the kth partial amplitudes vs. time for signals s1(t) and s2(t). Then the average error over time is given by e_ave = (1/DUR) SUM(t=0 to DUR) e(t) The theory is that given two syntheses of signal s1, namely s2 and s3, s2 is a better synthesis of s1 than is s3 if e_ave_2 < e_ave_3. This formulation seems to work fairly well, but it really fails when a synthesis has weak upper partials not found in the original. The weak upper partials contribute very little to the error calculation, but make a big difference in the perceived result. Therefore, it would probably be much better to add up the amplitudes within critical bands than to give all frequencies equal weights as we have been doing, and also to use an amplitude-to-loudness (in sones) translation. (Usually, S = K*A^0.6). The problem with equalizing the A(k,t) using the Fletcher-Munson curves is that one doesn't really know the absolute level of a given sound prior to playing it back, except in a lab testing situation, perhaps. Thus, the difference result would vary with playback level, an uncomfortable situation. From: Richard Parncutt ------------------------------------------------------------------------- The psychoacoustic distance between two steady state complex sounds (or its converse, perceived similarity) is influenced by a number of factors, including similarity of loudess, timbral similarity, and the degree to which the sounds have pitches in common (where by "pitch" I mean PERCEIVED pitch in the psychoacoustic sense.) Terhardt (1972) distinguished two kinds of pitch. Spectral pitches correspond to individual audible pure-tone components. Virtual pitches correspond to groups of audible pure-tone components whose frequencies form an approximately harmonic pattern, suggesting the presence of an (embedded) harmonic-complex tone. Most pitches perceived in everyday and musical sounds are virtual pitches. The relative perceptual salience of pitches may be estimated by the algorithm of Terhardt et al. (1982). Parncutt (1989) defined the pitch commonality of two complex sounds as the extent to which they have perceived pitches in common, depending on the number and salience of coinciding pitches (by comparison to non-coinciding pitches). Calculated pitch commonality values correlate well with similarity judgments of pairs of complex sounds that differ relatively little in loudness and timbre (Parncutt, 1989, 1993), and with music-theoretic accounts of the strength of harmonic relationship between musical tones and chords (Parncutt, 1989). From: Christopher John Rolfe ------------------------------------------------------------------------- Metrics have a long tradition in the literature, beginning with Fechner in the 19th Century.

Statement of Problem
: A report by Fairchild et al. (2003) indicated that Fort Cobb Reservoir is highly eutrophic. A greater understanding of the sources, loading, and effects of nutrients in runoff from the Fort Cobb Watershed is needed. This report formed the basis of an Central Region Integrated Science Proposal funded for 2006-2007 (Project 86420). The four disciplines within the USGS Central Region (Biology, Water, Geography, and Geology) are conducting an Integrated Assessment of the Fort Cobb Watershed. This task is the BRD component.
: 1) Determine the spatial and temporal trends in water quality within Fort Cobb Reservoir; 2) Quantify the degree of eutrophication of the reservoir; 3) Merge these data with those being collected by the other disciplines (Water: characterization of nutrient loading; Geology: remote sensing of the Watershed to characterize current land and water condition; and Geography: chronicle historic land use of the watershed)

Benefits Of Ranging Sensors
Perimeter intrusion detection sensors are highly effective solutions for securing a site. When buried, they provide a covert sensor that is virtually impossible for an intruder to bypass without being detected. When fence-mounted, they turn the existing fence into a smart fence, detecting any attempt to cut, climb, or break through its fabric. Detection at the perimeter enables the security system to respond while the intruder is still outside the protected area by calling up cameras and engaging deterrence devices like security lights and sirens.
Based on the granularity of alarm information presented to the security system, fence-mounted sensors can be divided into two categories: block and ranging.
This article looks at the differences between block and ranging perimeter intrusion detection sensors, and examines the key benefits of ranging sensors, including reduced nuisance alarms, software-based zones, and simplified troubleshooting.


."
Hare said zebras and other animals congregating around an African waterhole
know to scatter when they see a lion.
"There you can identify a predator, but psychopaths don't wear bells around
their necks," Hare said.
Psychopaths tend to thrive "where the rules are obscure, where there is chaotic
upheaval," Hare said. "Countries such as Yugoslavia and the Soviet Union after
their breakups were a warm niche for psychopaths, who simply moved in to take
advantage of the chaos."
A corporation that is disorganized and growing quickly offers the same type of
fertile environment, Hare said. In a book tentatively titled "Snakes in Suits"
to be published next spring, Hare blames scandals such as the destruction of
Enron at least partly on a category of psychopaths who typically know how to
stay out of jail.
Hare's checklist today has provided a generally accepted definition of the
psychopath, the "who" and the "what" that allows researchers from different
disciplines to study the phenomenon.
Hare says his checklist has been both abused and underused. He railed against a
judge in Texas, for instance, who has sentenced defendants to death because he
has deemed them psychopaths, even though they were never examined by people
trained to use his checklist.
But Hare also says many parole boards underutilize psychopathic evaluations
when considering whether to release a prisoner.
How a prisoner scores on the 20 characteristics of Hare's checklist "is the
best predictor of recidivism that we have," said Diana Fishbein, a researcher
at RTI International of Research Triangle Park in North Carolina.
About half of prisoners released from jail wind up back there within three
years, Kiehl said. The number skyrockets to at least 4 in 5 when the prisoner
is a psychopath. And psychopaths seem to be immune to any sort of therapy that
might better those odds.
One study explored whether group therapy might lower the recidivism rate of
psychopaths. Sixty percent of untreated psychopaths in the study were back in
jail after a year. But 80 percent of psychopaths who participated in group
therapy were convicted of another offense in the same period.
"They used the sessions to learn how to exploit the emotions of others," Kiehl
Some people debate the value of using the checklist to determine sentences for
individual killers. The recidivism rate is not 100 percent for psychopaths,
noted Dr. Michael Norko, director of the Whiting Forensic Division of
Connecticut Valley Hospital. And using the checklist is akin to doing a DNA
analysis for an incurable disease. What are you going to do if you find it?
"It would be different if we had a pill for psychopathy," Norko said.
Devoid Of Emotion
Kiehl says he believes that brain imaging studies can pinpoint the biological
cause of psychopathic behavior and possibly lead to a remedy, perhaps even a
psychopathy pill.
"If we could develop a treatment for psychopaths, it would alleviate an
enormous burden on society," said Kiehl, who is director of the clinical
cognitive neuroscience laboratory at the institute's Olin Neuropsychiatry
Research Center.
He has a theory of where in the brain to look. His previous work showed a
peculiar pattern of brain activity in psychopaths when they were presented with
different words or images.
Using both an electroencephalograph (EEG), which measures electrical activity
in the brain, and functional magnetic resonance imaging scans, which measure
oxygen use, Kiehl found striking differences between psychopaths and
non-psychopaths in the activity of several regions of the brain. He is
particularly intrigued by abnormalities in psychopaths' brains, in what he
calls the paralimbic system, a loose organization of brain structures involved
in processing emotion.
In most people, that picture of a distraught woman holding a dead child will
trigger heightened activity in these brain areas, including a region called the
amygdale. In contrast, the brains of criminal psychopaths respond much as they
would to any inanimate object.
Kiehl and other scientists have also found heightened brain activity in the
frontal cortex of psychopaths when they are presented with emotionally charged
words or images. The frontal cortex helps govern reason and planning.
Some scientists have interpreted that as evidence that the root of psychopathic
behavior lies in the frontal cortex. But Kiehl and others see it differently.
People with injuries to the frontal cortex do not exhibit the goal-directed
aggression or callousness often associated with psychopaths, Kiehl says.
Kiehl believes psychopaths enlist areas of the frontal cortex to process
information that the brain usually processes in its emotional centers.
On his desk at the Institute of Living, Kiehl keeps a replica of a railroad
spike, a memento of an 1848 accident that befell a Vermont construction foreman
named Phineas Gage. An explosion drove a 3-foot-7-inch tamping iron through
Gage's brain. The sheer improbability of his survival - the tamping iron
entered under his cheekbone, exited the top of his skull and landed 25 feet
away - assured Gage a place in the history of medical oddities. But the changes
in his behavior made him famous. Gage, who had been a reliable worker and a
sober, churchgoing, devoted family man, became an irresponsible cad, ignoring
his wife, children and job.
In short, he acted like a psychopath. Kiehl notes that the tamping iron damaged
the paralimbic system in Gage's brain, the same areas that seem abnormal in the
brain's of psychopaths.
Kiehl's theory explains, for instance, why psychopaths seldom seem to
experience anxiety or fear in the same way normal people do and why they do not
fully comprehend the meaning of emotions such as love or compassion.
"For a psychopath, it is all cognition," Kiehl said.
His lab has received federal grants totaling $6 million for the study of
psychopathy. In one study, he is investigating whether one reason that drug
abuse treatment programs have a high failure rate in prisoners is because so
many psychopaths are enrolled. Psychopaths do not respond to traditional
treatment and Kiehl suspects that, while psychopaths are heavy drug and alcohol
abusers, they do not develop the same sort of dependency on drugs as
To test his hypothesis, he hopes to persuade Connecticut correctional officials
to allow his team to study teen and adult inmates.
If Kiehl's ideas are borne out by research, they may suggest ways to change
psychopathic behavior. For now, Hare believes that any therapeutic approach
must appeal to the psychopath's own self-interest because treatments based on
an appreciation of somebody else's feelings are bound to fail.
Understanding the underlying physiology of the disorder could lead to a drug
that might actually restore emotional responses and cure psychopaths, said Dr.
James Blair, an expert in psychopathy and a researcher at the National
Blair points out that the symptoms of psychopathy are almost exactly the
opposite of symptoms of people who suffer from post-traumatic stress and
anxiety disorders - conditions for which treatments now exist.
Roots Of Morality
Kiehl hopes that by explaining how psychopaths' minds work, he can help arm
society with the tools to deal with them. One of his research associates, Jana
Schaich-Borg, also wants to answer a more fundamental question: Why are most
humans moral in the first place?
If Kiehl is correct that a failure of the emotional processing centers of the
brain is at the root of psychopathy, then it follows that moral behavior might
arise in those same areas. If a pill could create emotional responses in a
psychopath, could such a drug also give him a moral core?
Schaich-Borg plans to investigate whether psychopaths feel disgust - or the
deeply ingrained reaction that people in most cultures have about, say,
handling feces or having sex with a sibling. She speculates that the areas of
the brain that govern disgust in a normal person may also play a role in the
formation of more sophisticated moral beliefs, which are absent in psychopaths.
For years, the link between instincts and moral decision-making has been
inferred from fictional ethical scenarios. Schaich-Borg offers one example:
Five people are tied up on a railroad track and a locomotive barrels toward
them. You can save them, but only by pulling a lever and switching the
locomotive to a different track, where two other people are tied.
Do you pull the lever?
People answer instinctively, and study after study shows that they are split
right down the middle and argue their positions passionately.
"Some people say they won't play God under any circumstance," said
Schaich-Borg, who said she personally would pull the lever.
But what if you could save the people on both sides of the railway spur by
shoving a single man in front of the train?
"Nearly everybody says no," she said.
But, she said, a psychopath wouldn't care a whit whether the lever was pulled
or not. She wants to compare what happens in people's brains when


Coronavirus and Broken Contracts
Coronavirus (COVID-19) has left a trail of thousands of broken contracts in its wake in a wide range of industries. From event cancellations, to broken supply chains, Coronavirus has already caused millions of dollars in commercial losses and business interruption. Continued travel restrictions, event cancellations, school and business closures, quarantines, supply-chain disruptions, cash flow problems, and worker shortages is expected to increase over the coming months. This in turn has left businesses wondering—who is liable for the disruption?
One provision often contained in comprehensive contracts is that of "force majeure." Typically, force majeure provisions are included in contracts to excuse a breach if some unforeseen circumstances preventing a party's performance of the contract (ie, an act of God, such as hurricanes, war, earthquakes, etc.). The doctrine is also commonly referenced as "impossibility of performance."
Photo Credit: CDC/Alissa Eckert, MS, Dan Higgins, MAM
The concept of force majeure (French for "superior force") originated in the Napoleonic Code of 1804. The breaching party to an agreement was condemned unless their non-performance or delay in performance resulted from a cause that could not be imputed to them, and by a cause of a superior force or of a fortuitous occurrence.
For most businesses, Coronavirus is an unforeseen circumstance out of their control, however, the application of force majeure to any particular contract must be done applying the law of the relevant jurisdiction.
California law recognizes that parties may not be held liable when unforeseen circumstances prevent them from fulfilling their contractual obligations, whether or not the contract has a force majeure clause. The leading Supreme Court case in California defines force majeure as an "insuperable interference" occurring without the party's intervention that "could not have been prevented by the exercise of prudence, diligence and care." Insuperable in this context means "impossible to overcome." Although the case dates back to World War II, it has been cited as recently as 2015 as proper guidance for the interpretation of contracts.
For its part, the State of California defines force majeure in its standard Judicial Council contracts a "a delay which impacts the timely performance of work which neither Contractor nor the State are liable because such delay or failure to perform was unforeseeable and beyond the control of the party." The standard contract goes on to specifically list "quarantine or epidemic" as such a circumstance. Thus, quarantines resulting from the Coronavirus epidemic would render this provision operable.
Many contracts, however, do not contain specific language in force majeure provisions. Thus, each contract must be carefully analyzed with the law of the jurisdiction in order for businesses to understand their options.
Force majeure is one of many tools that business owners and individuals can use to mitigate the fall out from the current crisis. The bottom line is that businesses have options to escape ruinous consequences caused by circumstances beyond their control. Companies should seek legal counsel to navigate the ongoing effects of Coronavirus.

With installed wind energy capacity now over 539 GW, many turbines are reaching the mid to late stage of their operational life expectancy. Typically wind turbines have a life of about 20 years, but many only operate for the duration of the Power Purchase Agreement (PPA) under which they were constructed — which may only be 15 years.
Creating a strategic plan for asset life extension is critical for efficient management of wind farms. Clir Renewables recently launched a new product feature that allows for variable scenario analysis to determine the best way to operate assets.
As turbines age, owners and operators need to know how long their turbines are going to last. They often end up setting aside increasing amounts of budget for unplanned maintenance to ensure the asset is operating in a safe and profitable manner as various components approach the end of their design life.
However, an in-depth analysis of turbine data allows for the creation of strategic maintenance plans. These maintenance plans are created to prevent unexpected component failures and extend the operational life of the turbines. This is often undertaken as a one-off study assessing existing site data, which is unable to take into consideration true site conditions of the future.
Clir Renewables has tackled the industry issue of life extension analysis by developing detection tools enabling clients to assess and quantify the potential for life extension of their assets beyond 20 years and provide guidance for their maintenance planning.
Clir's software regularly analyzes wind-farm data, providing clients clear access to the information they need to make operational decisions in real time. Analytical models consider a wide range of data including wind flow conditions, component temperatures, and vibrational data. Each data set is then compared to the turbine design and loading parameters to quantify the operational risks turbines and individual components are exposed to. The software takes design loading conditions on a certification and site basis, compares it to real-world conditions derived from turbine data to quantify what risks turbines are exposed to and to what degree the turbines are operating within themselves.
This understanding gives Clir's clients actionable information to assist in long-term strategic maintenance planning and avoid unexpected component failures.
With Clir's software, continual assessment of component health ensures owners and operators are better informed about the condition of their assets and can build operational strategies in line with their long-term plans. The data can be fed into financial models, O&M strategies and assist in deciding whether to 'sweat' the assets during the PPA or extend their operational life past the agreement.
"Using automated algorithms and machine learning to assess wind turbine performance is an important advancement in the optimization of the wind industry," said Selena Farris, Data Scientist at Clir Renewables. "Continually assessing multiple data points across a site or portfolio means decisions are based on up-to-date rather than historical data. Better informed decisions reduce risk which can only be positive."

The natural dissipation of heat inside the electrical panels can be a solution assessable in the design phase, is often an insufficient solution: the size and position of the enclosure (and therefore the surrounding ambient air), the type of construction material, the distribution of power loads, the wiring and the space between the various devices are in fact "passive" elements, not negligible if we wants to accurately evaluate the dispersion of hot air.
As we have already seen, the electrical and electronic components inside the panel generate heat during their normal operation and a type of passive solution is often an insufficient method to maintain an optimal temperature inside the panel. The greater the number of devices, the greater the heat produced, so it becomes inevitable that we have to rely on active thermal management systems.
When natural heat dissipation is not enough
There are several impediments to using natural convection as a method for controlling the temperature in the electrical panel. For example, if hotspots located in certain areas are created inside the cabinet, it's necessary to intervene with a ventilation system that ensures proper air circulation and avoids overheating of the components.
Even in the case of applications in environments with high level of air contamination, such as petrochemical plants, paper mills or woodworking, or characterized by harsh climatic conditions together with a high thermal load, the dissipation of heat requires active thermal management solutions such as ventilation and cooling systems, possibly controlled by thermostats and hygrostats for temperature and humidity regulation, so to avoid unpleasant corrosion problems.
Finally, there are some application cases in which a closed loop cooling system is required, because impurities in the air can quickly clog the filtration system and therefore the consequent passage of air.
Solutions for heat dissipation
Fandis offers various solutions for temperature management, through a wide range of products:
- Filter fans and roof exhaust units: to cool the enclosure with filtered ambient air and different IP protection degree
- Cooling units: Peltier thermoelectric units for air conditioning and dehumidification of the air in electrical panels, suitable for situations with ambient temperatures above 35°C
- Anti-condensation heaters: to prevent the formation of condensation on the walls of the cabinet, which can put at risk the operation of the electrical components
- Mechanical and electronic regulators: to effectively manage, also from an energy point of view, the entire thermal system of the electrical panel.
The Fandis sizing software for electrical panels
On our website fandis.com, you will find a sizing software thanks to which it is possible to accurately evaluate the climatic conditions of an electrical panel, calculating the heating power or the cooling power necessary to obtain the optimal temperature inside it.

Inndeo, a Spanish company founded in 2016, uses Specim's hyperspectral imaging technology to improve the quality inspection processes in the food industry by increasing automation. With this new technology, they can detect contamination and defects in the production lines and characterize different food quality parameters.
From opportunity to an industrial partner
In 2014, Daniel Artal and Emilio J. de la Red found a business opportunity to integrate new technologies into quality inspection automation. They learned that the industry manages these duties with traditional manual labor and machine vision equipment with limited detection capabilities. So they founded Inndeo in 2016, and in 2018 started to work with hyperspectral imaging to detect more complex contamination problems.
Currently, they develop and manufacture machine vision solutions for the food industry under the INSPECTRA brand. With their approach of selecting the most appropriate technologies to solve their customer's quality problems and automate their production processes, they have gathered a clientele consisting of large Spanish food producers, especially in the meat sector.
Replacing manual labor and old equipment with sensor fusion
Today, food producers' main fear is losing brand image above all the costs and repercussions of quality failures. The solutions companies use in the food sector are X-ray equipment, metal detectors, and even manual operators for certain defects. There are some artificial vision machines on the market, but most of them cannot detect defects beyond a comparison of a color palette.
INSPECTRA's advantage is their integration of different technologies, sensor fusion, to improve the detection capabilities. One of the benefits is the digitalized quality and production data from the production lines. This high amount of data allows companies to apply BI techniques to rate their providers' quality and detect production inefficiencies to improve their productivity.
Advancing from detecting defects and contamination to quality parameters
The main challenge was to choose the most suitable vision technology for each of their equipment to capture and process the images online.
Hyperspectral imaging allowed them to perform the most complex contamination detection outside the visible light spectrum. Like melted grease in the heat-sealed area of packages, it goes undetected by the human eye and other inspection technologies.
"The main reason we decided to implement hyperspectral imaging technology in our equipment was that no other technology was able to detect particular contamination and defects in the products and also characterize different quality parameters of the food" says Emilio J. de la Red, Chief Technical Innovation Officer of INSPECTRA.
An added benefit was that they could classify different quality parameters from the food products with hyperspectral imaging.
The capture of hyperspectral images and the compose of chemical images requires a high load of computation. Moreover, integrating all that software in a robust machine that needs to work three shifts per day in a harsh environment was a challenge that required much hard work.
Both the use and the configuration of Specim cameras are simple in everyday life. They have the advantage of usability of a conventional camera despite being cameras with specific technology. The tricky part comes later, after the image capturing; the most challenging part is processing the images, associating the different spectral signatures, and obtaining the images in different tones according to the chemical composition.
Selecting the right partner
To succeed in integrating hyperspectral imaging into industrial equipment, INSPECTRA needed to choose the right partner. Specim is the world's leading provider of hyperspectral imaging and is selected by numerous research laboratories, including world-renowned centers. This gave them the confidence to start the collaboration. The decision was easy when they learned the features and benefits Specim offered as a supplier.
Emilio J de la Red confirms, "We have tested other suppliers for different types of technologies, but for hyperspectral imagining technology, we have trusted Specim since our beginning. We continue to work with them as a supplier to this day because they have always offered us the best solutions and have solved our problems very quickly whenever we have needed them."
Specim technology has allowed them to detect different types of defects and contaminations, undetectable to the human eye and other technologies. They have successfully used hyperspectral imaging in many various applications:
- Contamination of heat-sealed packages
- Contamination in shrimp and different fish production lines
- The freshness of different products, meat, fish, vegetables
- Contamination and quality of wool
- Composition and contamination detection of various minced meats
- Quality and contamination detection in pork meat
For example, they use Specim FX17 camera to classify different defects from the meat samples. Detecting PSE (pale, soft, and exudative) defects from the meat samples are difficult to see with the naked eye. The same goes for both bones and tendons.
" Yes, the solution met our expectations because we could superficially detect defects in meat samples that were difficult to distinguish due to the similarity with shades in certain parts of the meat through this technology. In addition, this technology allows us to know the different chemical components of each product or element and thus assign them a different color depending on their chemical composition." confirms de la Red and continues.
" We could detect foreign bodies, bleeding, PSE, tendons, bones, and cartilage in the samples without any problems. The only challenging defect is the holes in the meat. Hyperspectral cameras see the hole as an area of flesh (same material) but with shadow (less brightness)."
Endless amount of applications
The experience of working with Specim has been very satisfying for INSPECTRA. Both the cameras and the technology are easy to use and adapted perfectly to the different applications.
For the future, INSPECTRA is looking for native software from Specim, as the full integration into their machines has proven to be challenging with third-party software. However, given the multiple applications of the developed chemical image analyzing technology, they will apply it to developing new equipment to detect contamination and quality inspection of many different food items. In addition, in the long-term future, they may build products with this technology for other sectors.
When asked what Emilio J. de la Red would like to say to other companies looking for a technology partner, he concludes: "We would advise choosing Specim as a supplier of hyperspectral vision technology if they want to choose a supplier with solid experience, who offers a wide range of products to choose the technology that best suits their needs and offers excellent service and response time."

the clearing is a minimalist poetic sequence written by Luke Thompson and illustrated by Mairead Dunne. The poetry is a meditation on anxiety, hope and fear, displaced into the contained space of a clearing in the woods and into the birds themselves, who vocalise the disquiet as they pass into and out of the clearing. Using folklore and religious symbolism, these tiny illuminated moments begin to suggest broader themes and narratives. Mairead Dunne's illustrations interact with these themes brilliantly. Experimenting with lenses and with negative space, Mairead's work reflects and reveals the narrative, highlighting the sense of reader as voyeur, as well as developing the symbolism and ambience of the poetry.
Every copy of the clearing is unique, the cover birds having been individually hand-stamped by Mairead. The paper has been sourced from G.F. Smith and the book was litho printed at Booth's of Penryn.
"A bewitching collaboration between artist Mairead Dunne and poet Luke Thompson, the clearing examines the characters of birds and the relationships between them as different species cross the clearing and vanish into the dark woods. This is a beautiful book that appeals to the senses: the shadows and muted tones in Dunne's photographs contrast with the sharp observation of Thompson's writing, in particular an uncanny ability to evoke birdsong and flight patterns."

What is Environmental Medicine?
Environmental medicine involves diagnosing, treating, and preventing illness while looking at the effect our environment has on overall health. By taking into account both internal and external factors and focusing on the cause (or causes) of a disease and not just its symptoms, environmental medicine doctors hope to restore health to individuals suffering from chronic medical conditions such as asthma, irritable bowel syndrome and cancer.Environmental Factors that Cause Disease
Some of the external environmental triggers that can make people sick include:
Internal stressors are taken into account by environmental medicine as well. These include:
Environmentally Triggered Illnesses
While not every chronic illness is associated with environmental disease-causing factors, it is likely that there is an environmental component to most. With many long-term health conditions, standard therapies which treat the symptoms are not effective and do not contribute to a better quality of life.
Environmental medicine, which seeks out the root cause of the affliction, may prove more successful in treating many health ailments such as:
Treatment for Environmentally Triggered Diseases
Environmental medicine stresses early detection and prevention; however, for those already suffering from chronic illness, a customized treatment plan will be established to address the external and internal factors specific to the patient.
Forms of therapy that might be recommended include customized diets and nutritional supplements, immunotherapies, psychotherapies, detoxifications, limiting or eliminating environmental toxins, drugs, surgery and patient education for future prevention.

What is your Medical Risk Management Plan?
Did you know that:
 - The average emergency medical response time is 10-14 minutes (from first call to arrival of emergency personnel).
 - 5% of meeting attendees come to a meeting ill (up to 10% in winter months).
 - One in four international travelers will become ill while attending a meeting.
Have you ever experienced a medical emergency of any kind when you have been on-site for a meeting? How did you handle the situation? Did you communicate beforehand to your meeting participants what they should do in case of a medical emergency: who they should call in the hotel and they become sick or injured; where the closest/ best medical facility was that best fit their immediate needs, etc.? Like it or not, the unexpected does happen and you need to be prepared for any number of different scenarios.
With this in mind, it is imperative you have a Medical Risk Management Plan (MRMP) in place before an incident occurs so that when the unexpected happens everyone knows what to do and can stay calm and focused on the issue at hand. For starters, your MRMP should identify and/or answer questions like:
 - Your definition of a "routine medical emergency."This could be anything from a slip and fall to a cardiac event.
 - Other risks specific to your event and location that might occur such as altitude sickness and/or water sport activities.
 - Additional risks you need to be aware of if the group is traveling abroad, such as infectious disease, and potential food and water contamination.
 - Location of the closest and medical clinic and hospital to the meeting venue.
 - Are security personnel at the venue contractors or employees?Are they available 24/7? Are there at least two on-site at any given time?
 - What is the protocol for contacting security when an emergency occurs?
 - Are security personnel CPR and AED trained?Where are the AEDs located?
 - What is the closest entrance to the meeting room for emergency personnel to arrive at?Who from your staff will meet them?
 - Do the meeting rooms have house phones?What is the protocol for using, where do the calls go, who responds?
 - Does the venue have a physician on-site or on call?If yes, are they available 24/7?How do you or your guests reach them?
 - How/when do you communicate and to what extent do you communicate any or all of this information to your guests?
Have you considered having a physician or other medical personnel on-site during your meetings?
Having trained medical professionals on-site especially for large programs, high profile meetings such as Board of Directors Meetings, and/or international meetings where response time and/or quality of care may not be up to par would go far to insure that your medical emergencies were properly managed.We did have corporate security officers who traveled with us to our larger meetings and our Board of Directors Meetings who were CPR and AED trained and who could tend to the non-life threatening cases, and there were procedures to follow, but we didn't at the time have physicians or other medical/emergency personnel on site.However, one could make a pretty good argument for doing so in the right set of circumstances.
I recently had the opportunity to connect with Karen Moore, Sales Manager, with InHouse Physicians and learned some interesting facts about the organization she represents that I wanted to share with you.
InHouse Physicians was founded in 1992 by an Emergency Room physician by the name of Jonathan Spero, MD, who recognized a need for a service that provided on-call medical specialists to deliver VIP treatment to meeting attendees who become ill or injured while at a meeting venue after he himself had been asked by a meeting host he was an acquaintance of "if he knew of anyone who …. "
IHPs on-site medical personnel consist of board certified or board equivalent qualified physicians, mid-level support and paramedics assigned to your group 24 hours a day.Many of the physicians are board certified in emergency medicine and many are employed full-time as ER physicians in the hospitals where they reside.(Their ER schedules work well with their off-duty schedules.)
They provide concierge care services such as those middle of the night calls (whether sick or injured) to quick response emergency room type care to life threatening emergencies, and can go so far as setting up an actual ER setting at a venue complete with ER and ambulance equipment such as cardiac defibrillators, sutures, IV fluids, etc. They have a global network of credentialed and qualified specialty professionals available 24/7, and have admitting privileges at international hospitals (all English speaking).They make sure your attendees receive the appropriate care when they need it, while mitigating the risks associated with delayed or substandard care.
In addition to providing on-site medical care, they also set up Mobile Pharmacies that offer a wide range of frequently prescribed US medicines 24/7.
When you contract with IHP, they provide cell phone numbers directly to your attendees or through apps or other forms of communication you provide to your guests.
If you'd like to learn more about InHouse Physicians and/or how to medically risk-proof your meetings, contact Karen Moore | _PHONE_ | _EMAIL_. She'd welcome the opportunity hear from you.

Project looked at massive mobile launch platform, shuttle transporter
ALBUQUERQUE, N.M. - Sandia National Laboratories recently conducted a series of tests to help NASA understand the fatigue on the space shuttle caused during rollout from the Kennedy Space Center assembly building to the launch pad - a four-mile trip.
The tests are part of NASA's return-to-flight mission, with the first flight scheduled between May 15 and June 3.
Sandia, a National Nuclear Security Administration laboratory, helped NASA design the test and instrumentation to measure the dynamic vibration environment during rollout. Sandia also computed the input forces the crawler applies to the Mobile Launch Platform (MLP). These computations are being used by Boeing and NASA to determine the fatigue life for critical shuttle components.
Sandia engineer Tom Carne assisted in a series of tests beginning in November 2003 to develop the data necessary to understand the environment and the response of the space shuttle vehicle during rollout.
"NASA requested Sandia to assist them in this project because of our expertise in planning and conducting structural dynamic tests on very large structures," Carne says.
Sandia's solid mechanics/structural dynamics group has done numerous structural analysis projects on large structures including the I-40 Rio Grande bridge in Albuquerque, large wind turbines up to 110 meters tall, and the Department of Energy's Armored Tractor. One of the group's main missions is analysis and testing of the shock and vibration environments for weapons.
The three-million-pound shuttle sits on the eight-million-pound mobile launch platform, which is carried by a six-million-pound crawler. The crawler transports the vehicle and platform four miles from the Vehicle Assembly Building to the launch pad.
Moving the shuttle that distance, which normally takes five to six hours at 0.9 mph, had been considered a relatively low-stress process during most of the life of the shuttle system. As the equipment ages, however, more emphasis is being given to understanding how the rollout may fatigue the transport system.
Data were collected for rollouts of the MLP-only and the MLP with the two solid rocket boosters, at five different speeds ranging from 0.5 to 0.9 mph. For the tests more than 100 accelerometers were placed on the MLP, crawler, and solid rocket boosters. A data acquisition system installed inside the MLP for the road test measured and recorded the accelerations. The data were analyzed so that the character of the rollout environment is understood and can be analytically imposed on the shuttle using a finite-element computer model to predict fatigue damage to critical components. Even though these stresses are much lower than those seen during the launch, the fiveto six-hour duration of the transport and the low-frequency vibration could cause fatigue in components within the orbiter.
Carne says the rollout analysis team determined that there are two families of forcing harmonics caused by the crawler drive train that vibrate the platform as a function of crawler speed, in addition to the random inputs induced by the road bed. Fortunately, he says, the harmonic forcing frequencies can be adjusted by merely changing the drive speed of the crawler, resulting in less damaging frequencies.
The team used a Sandia-developed algorithm, the Sum of Weighted Accelerations Technique (SWAT), to estimate the applied forces. Carne says the SWAT results were beneficial in choosing a new rollout speed that will extend the fatigue life of the shuttle components that were affected by rollout.
The SWAT-generated input forces have subsequently been used as the force input for NASA's NASTRAN structural analysis of the mobile launch platform, emulating the test conditions. The correlation between the rollout-measured data and the predictions from the NASTRAN analysis has engendered confidence in both the SWAT-computed forces and the NASTRAN model of the MLP and solid rocket boosters, he says.
The analyses showed that the shuttle's vibration response can be much reduced when the driving frequencies are shifted away from the shuttle's own resonant natural frequencies. They helped NASA determine that merely reducing crawler speed from 0.9 mph to 0.8 mph would significantly reduce the vibrations in the shuttle by shifting the impact frequency of the crawler treads.

What is a turtle dove?
Turtle doves are the UK's fastest declining bird species and they are threatened with global extinction (IUCN Red List of Endangered Species).
Turtle doves are a vibrant, dainty species of dove (weighing in at around 140 grams) with a charismatic turrrturrr-ing call from which its name derives (click here to listen). In the UK it feeds in open habitats most commonly on arable and mixed farmland, where its staple food of wildflower seeds and farmed crop grains are found on the ground. Near to its feeding grounds, the species nests and roosts in open woodland edges, hedgerows and scrub areas.
Turtle doves are the only long distance migratory dove species in Europe, with their more common relatives such as the collared dove and wood pigeon staying in the UK year-round. They complete annual migrations from their breeding grounds, leaving in mid-late summer, through western Europe to their wintering grounds in West Africa; they typically return to their breeding grounds during April. The UK has around 14,000 breeding pairs of turtle dove according to their last national population estimation in 2009. The best chance you have to see the species is in East Anglia and South-east England, where the species has maintained its highest densities.
The full name for the species of turtle dove we get in the UK is the European turtle dove (Streptopelia turtur). There are 5 other species of turtle dove living around the world, out of a total of some 350 species in the dove and pigeon family alive today; 17 species of this family have already faced extinction because of humans, notably including the dodo and passenger pigeon.

In order to optimize the accuracy of the nearest-neighbor classification rule, a weighted distance is proposed, along with algorithms to automatically learn the corresponding weights. These weights may be specific for each class and feature, for each individual prototype, or for both. The learning algorithms are derived by (approximately) minimizing the leaving-one-out classification error of the given training set. The proposed approach is assessed through a series of experiments with UCI/STATLOG corpora, as well as with a more specific task of text classification which entails very sparse data representation and huge dimensionality. In all these experiments, the proposed approach shows a uniformly good behavior, with results comparable to or better than state-of-the-art results published with the same data so far

PostgreSQL function call model for PHP
This article describes a simple class that can be used to call PostgreSQL functions. Using the class has a number of advantages:
 1. PostgreSQL functions can be called like they are PHP method functions with no special syntax.
 2. The statements are automatically prepared giving faster execution for multiple calls.
 3. No string escaping is needed for prepared statements.
 4. The prepared statements are automatically deallocated when the object is destructed.
NOTE: PostgreSQL prepared statement support requries PHP 5.1 or later.
First, we create connect to PostgreSQL and create simple test function. The test function simply takes a string and a integer and concatenates a copy of the string the number of times specified by the integer.
$conn = pg_connect("dbname=test user=user1 password=user1");
if(!$conn) {
 echo "Unable to connect to test database\n";
// Here is our test function. Notice the pretty pgEdit SQL syntax coloring in PHP :).
$test_func = << 0 then
 for i in 1.. how_many loop
 result := result || str;
 end loop;
 end if;
 return result;
$$ language plpgsql;
// Create the function.
pg_query($conn, $test_func);
Next, let's test the function, using the typical PHP model with strings. If this was a real application, a lot more parameter checking would be in order.
$res = pg_query($conn, "select repeat_string('ab', 3)");
echo "\n\nTest 1:\n";
echo pg_fetch_result($res, 0);
Test 1:
Now let's create a class for calling PostgreSQL functions. We can create a single global instance of this class and use it throughout our PHP session. We could also create different instances if we are working with multiple connections. The key implementation detail takes advantage of the PHP __call magic method. This method is called whenever an unknown method for the instance is called. We can use this opportunity to call a PostgreSQL function with the same name and parameters.
class PgCall
 private $prepared = array();
 private $conn;
 // The contructor takes an existing connection, or a string to create a connection
 function __construct($connection_or_string) {
 if (is_string($connection_or_string)) $this->conn = pg_connect($c);
 else $this->conn = $connection_or_string;
 // Kill all the prepared statements.
 function __destruct() {
 foreach($this->prepared as $statement) {
 $res = pg_query($this->conn, 'deallocate'. $statement);
 // The __call magic method is called whenever an unknown method for the instance is called.
 function __call($fname, $fargs) {
 $statement = $fname. '__'. count($fargs);
 if (!in_array($statement, $this->prepared)) { // first time, not prepared yet
 $alist = array();
 for($i = 1; $i <= count($fargs); $i++) {
 $alist[$i] = '$'. $i;
 $sql ='select * from '. $fname. '('. implode(',', $alist). ')';
 $prep = pg_prepare($this->conn, $statement, $sql);
 $this->prepared[] = $statement;
 if ($res = pg_execute($this->conn, $statement, $fargs)) {
 $rows = pg_num_rows($res);
 $cols = pg_num_fields($res);
 if ($cols > 1) return $res; // return the cursor if more than 1 col
 else if ($rows == 0) return null;
 else if ($rows == 1) return pg_fetch_result($res, 0); // single result
 else return pg_fetch_all_columns($res, 0); // get column as an array
To use the class, we just create one instance of it and then we can call PostgreSQL functions without any special syntax or string escaping.
// Create an instance of the class using our existing connection.
$pg = new PgCall($conn);
echo "\n\nTest 2:\n";
echo $pg->repeat_string('a_b', 2);
Test 2:
The class returns the full resource if the result has more than one column. It returns an array if there is more than one row and a single column. You could imagine a variety of strategies and perhaps design slightly different classes depending on your needs. The foremost advantage is to remove as much SQL as possible from PHP and take advantage of the security and performance benefits of prepared statements.

Maker C.R.E.A.T.E Boot Camps
Creating Reality with Electronics, Art and Technology in Education
Re-discover the art of 'learning by making' and empower your students to tinker, design and make things using recycled materials and consumer electronics.
Teachers from any NSW school can book these full day excursions to MacICT. Our boot camps give students the opportunity to have the time, space and purpose to tinker. They provide a context for inquiry and discovery, leading students to become active problem solvers and engage in their own learning. These are critical practices for learning and discovery that have application across all curriculum areas.
Our Boot Camps are introductory and are designed for beginners. However they are flexible in nature so please let us know if you would like to work with us to design a day that meets your students' needs.
In this excursion, students will participate in tactile building tasks and electronic circuit wiring, as well as specific computer coding activities for older students. Program, build and electrify activities will address a real world need, and students can also take their projects home to keep! Total cost is inclusive of all materials required.
Our MakerDay C.R.E.A.T.E! Boot Camps were first inspired by the growing popularity of D.I.Y. building and tinkering projects that have now reached epic proportions in the United States. Research around this phenomenon has, among other things, highlighted that the art of making is inherently a human activity and one that is very satisfying. The resurgence of the 'Maker' movement has expanded to include the ability to code and program for the demands of an increasingly digital and automated world.

Chicken feathers, as unlikely as it seems, have turned out to be a wonderfully useful material. Among other things, researchers have found they make for great circuit boards and cheap, efficient storage tanks for hydrogen. Now it turns out they could also be used to create biodegradable, petroleum-free plastics.
Researchers at the University of Nebraska-Lincoln say that the protein keratin in chicken feathers, which is strong and durable, as well as the fact that so many of them end up as unused waste, is what makes them such an appealing material. When making the plastic, the scientists heat-treated the feathers to clean them and then pulverized them into a fine powder. They then added chemicals that made the keratin molecules join together into long chains and create a polymer.
The resulting plastic was stronger than other bioplastics made of soy beans or starch and it stood up to water. The material is a thermoplastic which means that heat can be used to mold it into various products and can be melted and remolded many times. It could be used for plastic plates and cups or even furniture and when those things are no longer usable, the plastic is biodegradable.
