GOVERNMENT water inspectors plan to prosecute South West Water after more than 300 people in Devon suffered severe and long-lasting diarrhoea last month when their water supplies were contaminated with the spores of Cryptosporidium, a protozoan parasite, from animal wastes. It was the worst outbreak caused by contaminated water supplies for six years.
Water scientists believe the latest outbreak may have arisen because the company failed to change procedures at the Littlehempston water treatment works as it juggled different supplies of water during the drought. South West Water refused to speculate, but a company engineer said it was reviewing the management of water at the plant.
The outbreak calls into question the effectiveness of a £4 million research programme carried out by the water industry in an effort to prevent a repeat of a similar incident in Swindon in 1989, when at least 500 people became ill. An evaluation of...

Review: Another Round (SFF Summer Season)
Another Round is an alcohol-fuelled dark comedy.
Photo: Henrik Ohsten
Viewers familiar with Thomas Vinterberg's The Hunt (2012) will have a very different experience with the Danish director's latest outing. An alcohol-fuelled dark comedy, Another Round explores the consequences of four high school teachers and their experiments with alcohol during work hours. A simple plot that manages to unfold into tragic carnage, its protagonists are deconstructed by their efforts to dive deeper into their indulgence. Vinterberg has crafted a film that is incredibly funny, whilst remaining acutely aware of the complexities of human emotion. The punchlines are strong and the consequences hit hard. A coming of middle-age drama, Vinterberg uses alcohol as a vehicle to confront the internal anxieties born from our feelings of failure.
The film opens with a scene familiar to many Australians: a teenage drinking ritual. The Danish high schoolers race in a relay around a lake. Each team member must sink a beer at the different benches along the way, incentivised by the prospect of winning the proceeds from the recycled beer bottles. An incredibly catchy pop song blares over the festivities while the adults watch on in glee. Vinterberg doesn't utilise the scene as a condemnation of youth drinking; instead, it represents a moment of joyous mischief, chaos and unity. It is this attitude of ambivalence that makes Another Round both a celebration of the revelry that can come from the consumption of alcohol, and a meditation on the importance of moderation.
This messaging is largely carried by the performance of the film's lead, Mads Mikkelsen. Mikkelsen plays a high school history teacher, Martin. A husband and father of two, Martin has slipped into the monotony of middle age, going through the motions of the day, devoid of spark and charisma. This changes when he attends the birthday party of his friend and fellow staff member, Nikolaj. A psychologist, Nikolaj proposes an experiment where they see if a higher blood alcohol content will improve their quality of life. This experiment brings a new spark to their experiences.
The teacher's experiment leads to an array of inebriated hijinks, filling the cinema with laughter for much of the first act. The teachers enthusiastically lead classes while drunk, coach childrens' soccer matches and try to make their way undetected through staff meetings. This initial comedy escalates into absurdity, making the slowing down that comes afterwards more poignant, as the protagonists reap what they have sowed. As Vinterberg puts his characters through the extremes, he pauses to question if their initial newfound happiness is all placebo. The film is well paced but does take its time to transition into the third act. However, this isn't a bad thing, as Vinterberg's visuals and the dynamics he establishes between characters are a joy to watch.
An important way that Vinterberg's comedy stands apart from its American counterparts is through its attention to the craft of cinema. Beautifully composed, Vinterberg's DOP Sturla Brandth Grøvlen mimics the cerebral uncertainty induced by alcohol. The camera refuses to stay stable, even in the film's most intense moments, with handheld shots and shallow depths of field leaving the audience with a feeling of uneasiness and uncertainty. While these cinematic choices effectively connect the craft of the film to its themes, it also harkens back to Vinterberg's early career. A founder of the Dogme 95 movement with Lars Von Troyer, the young Danish filmmakers railed against the conventions of cinema. Dogme 95 restricted the filmmaking means of its followers through the signing of a vow of chastity. Directors were forbidden from the use of custom props, tripods and special effects, and instead had to 'live in the moment'.
In 2002, David Bowie challenged Vinterberg on the sincerity of the movement, stating that it sounded like a satirical affair. Vinterberg responded that it was in fact a genuine heartfelt attempt to break the conservative mould of film. These naturalistic qualities of filmmaking are resonant throughout Another Round. Vinterberg paints the protagonists as creatures on a knife's edge; teetering on the edge of primality within their urban environments.
Much of Another Round's meditation on alcohol and the rollercoaster of life can be attributed to the personal tragedy faced by Vinterberg during the film's early production, as Ida, Vinterberg's 19 year old daughter, was tragically killed in a car accident. Vinterberg uses Another Round to preach a sermon about life, showing the audience the pleasures of risks and the pitfalls of excess. He invites audiences to realise that they need to take chances, experiment and explore because there is still time left. The film embraces the spectrum of effects of Danish drinking culture, weighing both the positives and negatives of alcoholic escapism. Another Round will continue to resonate as people return to a sense of normalcy following the pandemic, and have to come to terms with how to enjoy the world despite the anxieties and failures of the past.

The most inventive way a patient may use to pass an observed urine drug screen and how to prevent it
Article By: MichaelS76

A review of the most devious yet ingenious way a patient will use in order to pass an observed urine drug screen and how to circumvent it.
Submitted:Aug 16, 2013 Reads: 68 Comments: 0 Likes: 0
The most desperate patient may perform the following:
1. The patient should abstain from illegal drug use for as many days as possible before the test. Within 24 hours of the test, the user should drink considerable quantities of water.
2. Just prior to the test, the user must void the bladder completely.
3. A fresh urine sample must be obtained from a donor, whose urine has the proper constituents or contains no illicit drugs.
4. A Foley catheter is then passed through the user's urethra and into the bladder.
5. The donor's urine is passed through the catheter and into the user's bladder.
6. Then the user must have the drug screen performed as soon as possible to prevent any drugs or metabolites from being processed by the kidneys and secreted into the donor urine.
7. The urine from the donor should match the sex of the patient. Estrogen levels appropriate for a woman would look mighty strange in a man's urine (although drug tests don't normally check for such things.
This is the most desperate attempt a patient may take in order to pass an observed drug screen. If a patient is suspected of tampering with his or her urine an observed drug screen should be performed. If that same patient is suspected of further tampering then the only way to ensure that a proper urine specimen is obtained is to have the patient urinate completely under observation, then have the patient drink copious amounts of water and wait at least 1 hour before collecting another observed specimen. This ensures that the urine contained in their bladder has actually come from the patient and not a donor patient. This is one of two ways to be 100 percent sure that a patient's urine drug screen is accurate, even under observation. The other way is to collect a blood specimen for analysis.

Let's say one says borei ha'adamah or ha'eitz and eats at least a kezayis of a fruit or vegetable, but is not yet full. Then, the person decides that he or she wants to eat bread. Is the proper procedure to say borei nefashos first, or to say hamotzi and then afterward say birkas hamazon and borei nefashos?
If the answer is that one should say the brachos achronos before hamotzi, what should one do if one forgets to do so before saying hamotzi? In such a situation, should one say it in the middle of the meal, or wait until after birkas hamazon?
share|improve this question
Is he planning on eating any of the fruit/vegetable during the bread meal? – Double AA May 15 at 15:45
I don't know -- does the answer depend on that? – Kordovero May 15 at 15:56
1 Answer 1
Mishnah Berura 176:2 -
If he is planning on eating more fruit during the meal, and had in mind to continue eating the fruit during the meal, then it is all considered part of the meal and he does not make a borei nefashos, not before hamotzi and not after, as it is covered by the birkas hamazon that he will say.
If he does not plan to continue eating more during the meal, then he needs to make a borei nefashos. This borei nefashos should be made even during the meal. The implication of the Mishnah Berura is that it doesn't matter at what point you make the borei nefashos, as the eating of the fruit had nothing to do with the meal, and it could even be after birkas hamazon.
If he ate a vegetable (or any food that does not need a beracha when eaten during the meal) then he makes a borei nefashos even if he eats more during the meal, as the original pre-meal eating was perforce not part of the meal.
share|improve this answer
Thanks! I'm a little confused about your last sentence. Are you saying it's different between eating fruits and vegetables? Do you mean that he makes the borei nefashot before the meal in that case? Or is it just the same as the fruit example? (I guess the difference would be that one says ha-eitz even during a bread meal, if one already said borei nefashos?) – Kordovero May 16 at 13:20
_USER_ It is the same as fruit in the case that you do not plan to eat more during the meal. In the case of a vegetable, it is automatically treated as if you do not plan to have more. – YeZ May 16 at 17:47

Robust Real-Time Optimization of a Solid Oxide Fuel Cell Stack
On-line control and optimization can improve the eﬃciency of fuel cell systems whilst simultaneously ensuring that the operation remains within a safe region. Also, fuel cells are subject to frequent variations in their power demand. This paper investigates the real-time optimization (RTO) of a solid oxide fuel cell (SOFC) stack. An optimization problem maximizing the efficiency subject to operating constraints is deﬁned. Due to inevitable model inaccuracies, the open-loop implementation of optimal inputs evaluated oﬀ-line may be suboptimal, or worse, infeasible. Infeasibility can be avoided by controlling the constrained quantities. However, the constraints that determine optimal operation might switch with varying power demand, thus requiring a change in the regulator structure.

Study Says Gay and Lesbian Couples Happier Than Their Straight Counterparts
Submitted by Take Out on Tue, 02/06/2018 - 23:05
Gay and lesbian couples have happier relationships than their straight counterparts, according to new research.
Academics behind the research say it counters the stereotype that same-sex relationships are conflictual, unhappy and dysfunctional.
The research, based on surveys of over 25,000 people in the UK and Australia, is published in the academic journal Family Relations.
It found that UK gay and lesbian couples had a relationship quality as high as their straight counterparts, while in Australia it was higher than heterosexuals.
Its authors have offered possible explanations for why homosexual relationships are happier. They said same-sex couples and particularly women are more likely to share domestic labour equally and this means there is less conflict.
Gay and lesbian people are also more likely to feel part of a community, and this could enhance their self-esteem and allow them to experience higher levels of wellbeing.
They could also be more invested in their relationships given the personal and institutional barriers that they have to overcome as members of a sexual minority.
The research also found bisexuals experienced lower relationship quality than gay, lesbian and heterosexual people. The authors claim this could be due to bisexuality being a silenced and invisible sexual identity, with bisexuals not fitting into the gay or lesbian communities or the heterosexual majority.

WESTON Museum has been transformed into an archaeological dig pit in a bid to inspire youngsters about our past.
The Burlington Street museum will hold its Big Dig event every week day until August 21, with an exhibition teaching children about archaeology and history.
The event, the brainchild of Bournemouth University student and museum volunteer Shauni Brocklesby, features a large sand pit containing treasures for children to dig up.
They are also being taught how to write their names using Viking runes and Egyptian hieroglyphics.
Museum supervisor Adam Brown said: "We are really hoping that this will plant seeds of interest into children and advance their understanding about this amazing subject."


The embarrassing issue of humping
Rate this article:
Many dog owners will be familiar with the awkward scenario of their dog unexpectedly humping another dog, an inanimate object, or even a human leg. So why do dogs hump and should we do anything about it? Ross McCarthy, canine behaviourist of the London Dog Behaviour Company, answers some common questions on the subject
Is it sexually motivated?
Sometimes, but, depending on the age and gender of your dog, humping, as we call it, is most commonly an exploratory behaviour. It's governed primarily by initial excitement and touch in certain places that create arousal.
Essentially, it's a pleasurable activity for an excited dog, and it can become an embedded response in certain situations: while some dogs may run and grab a toy or slipper when you come home, others might go and mount their bed.
Why do my dogs tend to hump more when visitors come round?
It's not sexual – dogs just get excited at the change in the norm. So when visitors come, life is fun and exciting and they hump as a type of displacement behaviour, transferring their feelings about the event to something else.
It may also have something to do with your responses and those of the visitors: if a dog's excitement is stoked by all the attention and fuss that could be a reason to continue with the behaviour that incited the reaction.
My dog is neutered. Why does he still hump?
In purely biological terms, unneutered male dogs want to mate bitches in season – that's it. There are, of course, exceptions, such as when they get a scent that they like on someone or something. But the impulse is largely reserved for when they get that unmistakeable, innate mating message via scent.
Neutering helps to decrease the amount of testosterone (a sex hormone) in a dog's body, lessening the urge to mate, and therefore to hump. However, a certain amount of the hormone remains in the dog's bloodstream, meaning they'll continue to want to mate and, by extension, will continue to exhibit mounting behaviour.
Bear in mind, too, that humping is learned and practised from puppyhood (well before sexual maturity). It's a way for dogs to test out their physical abilities and social potential – more dominant members of the litter will assert themselves by mounting their siblings, thereby displaying leadership or dominance.
Why do female dogs hump?
It's common for female dogs to hump too, particularly in puppyhood (although not usually as much as males do). The reason is simple: it feels pleasurable to them and is simply an intrinsic behaviour, motivated by play and social interaction in the same way as it is for male dogs. Some dogs (of either gender) might hump in response to stress as well as excitement, so it's useful to watch your dog's humping habits to see if something in particular is agitating him or her.
What should I do about the humping?
Probably nothing. My 16-year-old neutered German Shepherd, Vhko, likes to try to mount my youngest Rottweiler, Rohkh, for a short while after their evening meal. Both dogs seem to enjoy the interaction, so I allow it to continue. I think if the routine included humans, I might put a stop to it, but if you have a puppy who's humping his bed or a toy, you should probably just leave him alone to get on with what is fundamentally a natural, normal canine behaviour.
However, humping can sometimes have an underlying medical cause, such as a urinary tract infection or skin allergy, so if the behaviour has come on suddenly or seems excessive, it's worth asking your vet about it – particularly if your dog is also spending a lot of time licking his or her genital area.
If you've ruled out a medical reason and are still concerned that the humping is getting out of hand or happens too frequently, you should use positive reinforcement training to stop the habit and teach an alternative response. A qualified behaviourist can help you to assess the situation and take the best course of action.

Oldest Human Footprints Outside of Africa Found
By Carl Engelking | February 7, 2014 1:28 pm
Researchers discovered the oldest human footprints outside of Africa in Britain.

Citizens of Britain can now trace their origins several large steps backward in time. Archaeologists recently discovered the oldest set of human footprints outside of Africa along the eastern coast of Britain.
Rough seas last summer in the village of Happisburgh, Norfolk, washed away portions of the shore revealing a set of about 50 footprints. Researchers estimate the prints are between 800,000 and 1 million years old, which is now the oldest evidence of early humans ever found in northern Europe.
Footprints' History
Due to the various sizes of footprints, researchers believe a mixed group of at least five adults and juveniles were walking along mudflats of what was then the Thames River estuary. Based on the size of the prints, researchers believe the group was related to Homo antecessor, or "Pioneer Man," which died off some 800,000 years ago. The group was likely scouting the area for food, and could have been related.
Researchers found 50 footprints from a group of five adults and juveniles.
Prior to the Norfolk find, the oldest human remains found in Britain were a set of tools dating back 700,000 years. Older human evidence tends to be found in southern Europe where researchers, for example, have unearthed 780,000-year-old skull fragments in southern Spain.
The Norfolk find sheds new light on the tenacity and adaptability of northern Europe's earliest human ancestors, Chris Stringer, an archaeologist with the project, told the Associated Press:
A Rare Find
The discovery is significant to our understanding of human origins, but it's also incredibly lucky. Finding preserved footsteps is difficult, given the punishing forces of erosion along seacoasts. Previously, the record for the oldest set of footprints in Britain was 7,500 years old, which pales in comparison to the Norfolk find. The Norfolk team called the Happisburgh prints a "one in a million" find.
Fortunately, archaeologists captured plenty of photographic evidence to study Britain's oldest footprints in May 2013, because what the sea gives it also takes away. Most of the ancient footprints have already disappeared due to erosion. However, researchers are optimistic that the same forces could someday unveil new evidence, as well.

 I'm not going to argue with you. but the fact is, no matter how much we think we know scientifically. It always gets proven wrong.
 The only thing I can say is use current data / methods (even if flawed) write as many books using those, swear it's all true, make a living pushing whatever current truth there is.
 After all a candle in a glass once filled it with a chemical called Phlogistin that extinguished the flame. THEN later after people were rewarded for those discoveries did we discover it was actually the lack of O2 to oxidize the hydrocarbons.
 Truth is, most science has flaws including evolutionary man. But don't let that stop any of us from trying to make bank off it while people still believe it.
 - _URL_ Peter French
 All science can do is theorize from the evidence available. Until there's new evidence that disproves the theory, it's the best there is. Is that flawed? I don't think so. You might say the existence of a chemical known as Oxygen is just a theory, but it works better than Phlogiston.

 1) Did H. antecessor interbreed with or evolve into H. neanderthalensis? Because otherwise it would be hard to say we descendants of the Brits have the prior as Ancestors. Possible, but hard. If they did not become or interbreed with Neanderthals, their descendants could also have bred with early modern humans in one of the earliest of those expansions, but, ahem, 'proof, please.'

By Nadia Drake | Wired.com
A spider that builds elaborate, fake spiders and hangs them in its web has been discovered in the Peruvian Amazon.
Believed to be a new species in the genus Cyclosa, the arachnid crafts the larger spider from leaves, debris and dead insects. Though Cyclosa includes other sculpting arachnids, this is the first one observed to build a replica with multiple, spidery legs.
Scientists suspect the fake spiders serve as decoys, part of a defense mechanism meant to confuse or distract predators. "It seems like a really well evolved and very specialized behavior," said Phil Torres, who described the find in a blog entry written for Rainforest Expeditions. Torres, a biologist and science educator, divides his time between Southern California and Peru, where he's involved in research and education projects.
"Considering that spiders can already make really impressive geometric designs with their webs, it's no surprise that they can take that leap to make an impressive design with debris and other things," he said.
In September, Torres was leading visitors into a floodplain surrounding Peru's Tambopata Research Center, located near the western edge of the Amazon. From a distance, they saw what resembled a smallish, dead spider in a web. It looked kind of flaky, like the fungus-covered corpse of an arthropod.
But then the flaky spider started moving.
A closer looked revealed the illusion. Above the 1-inch-long decoy sat a much smaller spider. Striped, and less than a quarter-inch long, the spider was shaking the web. It was unlike anything Torres had ever seen. "It blew my mind," he said.
So Torres got in touch with arachnologist Linda Rayor of Cornell University who confirmed the find was unusual. "The odds are that this [species] is unidentified," she said, "and even if it has been named, that this behavior hasn't previously been reported." Rayor notes that while more observations are necessary to confirm a new species, decoys with legs — and the web-shaking behavior — aren't common in known Cyclosa. "That's really kind of cool," she said.

If you own a Volkswagen, you may have experienced the unsettling feeling of the EPC light coming on and your car shaking. The EPC light, which stands for "Electronic Power Control," is a warning light that indicates a problem with your vehicle's engine management system.
When the EPC light comes on, you may also notice your car shaking or vibrating while driving. This can be a cause for concern, as it can compromise your vehicle's and its passengers' safety.
In this guide, we'll explore the causes, signs and symptoms, and repair options for Volkswagen EPC light and car shaking issues.
So, let's dive in and learn more about this common issue that Volkswagen owners may encounter.
What is the EPC Light?
The EPC Light, or Electronic Power Control Light, is an indicator light that can appear on the dashboard of Volkswagen vehicles. It's designed to alert the driver that there's a problem with the engine's electronic control module (ECM) and related systems.
The ECM is responsible for regulating many important functions of your vehicle, such as fuel injection, ignition timing, and throttle control. If there's an issue with any of these systems, the EPC Light may illuminate to let you know that there's a problem that needs to be addressed.
Causes of Volkswagen EPC Light and Car Shaking
Here are some potential causes of Volkswagen EPC Light and Car Shaking:
1. Faulty Throttle Body or Sensor
The throttle body controls the amount of air that flows into the engine. If the throttle body or its sensors are faulty, it can cause issues with the engine's airflow and result in the car shaking and loss of power.
2. Vacuum Leaks
The engine relies on a vacuum system to operate certain components, such as the power brakes and the HVAC system. If there is a vacuum leak in the system, it can cause car shaking and also trigger the EPC light.
3. Fuel System Issues
A clogged fuel filter, a malfunctioning fuel pump, or a faulty fuel injector can all cause issues with the engine's fuel delivery, resulting in the car shaking and potentially triggering the EPC light.
4. Ignition Coil Problems
The ignition coil provides the spark that ignites the fuel in the engine. If the ignition coil is faulty, it can cause misfires and result in the car shaking and a loss of power.
5. Engine Misfires
Misfires occur when the fuel in the engine fails to ignite properly. This can be caused by a variety of issues, including a faulty ignition system, worn spark plugs, or a dirty fuel system. Misfires can cause car shaking and trigger the EPC light.
6. Transmission Issues
Transmission problems, such as slipping or shifting issues, can cause car shaking and also trigger the EPC light.
7. Other Potential Causes
Other potential causes of Volkswagen EPC Light and Car Shaking issues can include problems with the engine sensors, the catalytic converter, or the engine control module.
Signs and Symptoms of Volkswagen EPC Light and Car Shaking
1. EPC Light
The most obvious sign that there is an issue with your Volkswagen is when the EPC light comes on. This light is typically located on the dashboard and will illuminate when there is a problem with the engine management system. When the EPC light comes on, it's important to have your vehicle inspected as soon as possible to prevent any further damage.
2. Car Shaking or Vibrating
If you notice that your Volkswagen is shaking or vibrating while driving, it may be a sign of engine misfires or transmission issues. These issues can cause a loss of power and reduced performance, making it more difficult to drive your vehicle safely.
3. Reduced Power
If you notice a significant reduction in power when driving your Volkswagen, it may be a sign that the engine is not operating at full capacity. This can be caused by a variety of issues, including faulty sensors or engine misfires.
4. Engine Stalling
In some cases, the engine may stall or shut off completely when there is an issue with the EPC system. This can be particularly dangerous if it happens while driving at high speeds or in heavy traffic.
5. Warning Messages
Depending on the severity of the issue, your Volkswagen may display additional warning messages on the dashboard or through the infotainment system. These messages may include "Reduced Engine Power" or "Check Engine."
Fixing the Volkswagen EPC Light and Car Shaking
1. Throttle Body Cleaning or Replacement
If the issue concerns a faulty throttle body or sensor, cleaning or replacing the throttle body may solve the problem. This can be done by a professional mechanic and should be performed as soon as possible to prevent further engine damage.
2. Vacuum System Inspection and Repair
If there is a vacuum leak in the system, a professional mechanic can inspect and repair any damaged hoses or components to ensure proper vacuum operation. This can help prevent future EPC light and car shaking issues.
3. Fuel System Inspection and Repair
If the issue is related to the fuel system, a professional mechanic can perform a fuel system inspection and repair any faulty components, such as a clogged fuel filter or a malfunctioning fuel pump. This can help ensure proper fuel delivery to the engine and prevent further damage.
4. Ignition System Inspection and Repair
If the issue is related to the ignition system, a professional mechanic can inspect and repair any faulty components, such as the ignition coil or spark plugs. This can help prevent engine misfires and ensure proper engine operation.
5. Transmission Inspection and Repair
If the issue is related to the transmission, a professional mechanic can perform a transmission inspection and repair any faulty components, such as slipping or worn gears. This can help prevent further transmission damage and ensure proper transmission operation.
Prevention of Volkswagen EPC Light and Car Shaking
1. Regular Maintenance
Regular vehicle maintenance is key to preventing issues with the EPC system and car shaking. Follow the manufacturer's recommended maintenance schedule and have your vehicle inspected by a professional mechanic at least once a year.
2. Quality Fuel
Use high-quality fuel and keep your gas tank above a quarter tank to ensure proper fuel delivery to the engine. Low-quality fuel or a low fuel level can lead to engine misfires and other issues.
3. Clean Air Filters
Replace your air filters at least once a year to ensure proper airflow to the engine. Dirty air filters can lead to reduced engine performance and other issues.
4. Proper Driving Habits
Avoid harsh driving habits, such as sudden acceleration or hard braking, as this can put unnecessary stress on the engine and other components. Additionally, avoid overloading the vehicle, as this can put extra stress on the engine and transmission.
5. Address Issues Promptly
If you notice any signs or symptoms of an issue with your Volkswagen, such as the EPC light or car shaking, have your vehicle inspected by a professional mechanic as soon as possible. Ignoring the issue can lead to further damage and potentially dangerous driving conditions.
When experiencing the EPC Light and car shaking issue with your Volkswagen, it's crucial to take it seriously and have it diagnosed and repaired promptly.
Ignoring the issue could lead to further problems down the road. If you're not comfortable diagnosing or repairing the issue yourself, don't hesitate to seek out the help of a professional mechanic who has experience with Volkswagen vehicles.
With the right care and attention, you can keep your Volkswagen running smoothly for years to come.

Happy New Year! And best wishes for a healthy and prosperous year for all my readers and their families.
On the first day of a new year it seems appropriate to write an exercise based on calendars. Unix provides a
cal command to print calendars. There are several forms:
cal— prints a calendar for the current month
calyear — prints a twelve-month calendar for the specified year; note that year 10 occurred during the time of Christ, so you must specify 2010 for the current year
calmonth year — prints a calendar for the specified month and year; the month is given as a number from 1 to 12
cal -3— prints a three-month calendar for the prior month, current month and next month
The current date is highlighted wherever it appears.

Determinants of Technology Adoption: Private Value and Peer Effects in Menstrual Cup Take-Up
We estimate the role of benefits and peer effects in technology adoption using data from randomized distribution of menstrual cups in Nepal. Using individual randomization, we estimate causal effects of peer exposure on adoption; using differences in potential returns we estimate effects of benefits. We find both peers and value influence adoption. Using the fact that we observe both trial and usage of the product, we examine the mechanisms driving peer effects. We find that peers matters because individuals learn how to use the technology from their friends, but that they do not affect individual desire to use the cup.

A localization method based on an enhanced particle filter incorporating tournament selection and Nelder-Mead simplex search (NM-EPF) for autonomous mobile robots navigating in a soccer robot game field is proposed in this paper. To analyze the environment, an omnidirectional vision device is mounted on top of the robot. Through detecting the white boundary lines relative to the robot in the game field, weighting for each particle representing the robot's pose can be iteratively updated via the proposed NM-EPF algorithm. Thanks to the hybridization effect of the NM-EPF, particles converge to the actual position of the robot in a responsive way while tackling uncertainties. Simulation and experiment results have confirmed that the proposed NM-EPF has better localization performance in the soccer robot game field in comparison to the conventional particle filter.

My general question is when should one use OLS and when binomial regression when the outcome is count data with a fixed upper limit. When the upper limit is large (like 1000) and most values are around 500, residuals can still be almost exactly normally distributed. However, when the number of trials is very low (like 3) normality assumption obviously cannot hold.
Is there a rule of thumb for the minimum number of trials such that OLS can be used (of course normality of residuals still should be checked)? Furthermore, if normality of residuals is approximately normal with OLS, what is the downside of using binomial regression?
In our case, we have a few different data sets where the outcomes are always (integer) scores on different tests. The score indicates how many exercises could a subject solve from the given test. The maximum scores can vary between different tests although they measure the same thing. There are tests with a maximum of 3 points, and tests with a maximum of 30. I guess with 30 points OLS might work, but not with 3. Should we just analyze everything with binomial (of course again, we need to check the assumptions)
Bonus question: If we fit OLS and binomial regression to the dataset with max 30 points, and one of the coefficients is significant for the OLS estimate but not significant for the binomial one, how can we interpret this?
 - $\begingroup$ You need to give us more details! What is the integer scores, that does not sound like counts? Assuming they are binomial counts, why not use logistic regression, which has NO normality assumption? There is little to gain by using OLS, when assumptions are not met... $\endgroup$ – kjetil b halvorsen Jun 4 at 22:00
 - $\begingroup$ That would also be my guess. However, we are reanalyzing articles and they all used OLS for tests where sometimes the maximum score was 5 or 10. The score indicates how many exercises could a subject solve from the given test. $\endgroup$ – zerz Jun 5 at 8:22

Flag of Greece
The flag of Greece is rectangular with nine equal stripes of blue (5) and white (4) from left to right. In the top left corner is a blue square with a white cross. This flag has been used since 1822, when the young Greek state was fighting for its independence from the Ottoman Empire during the Greek War of Independence.
The current flag of Greece was officially adopted during the First national assembly of the Greeks at Epidaurus in 1822, and the flag with the 9 stripes was adopted as a state and military ensign (a flag used only by the government and the military, and only on ships). Another flag was chosen as a land flag, it was a simple white cross on a blue field. A third flag was adopted for the merchant fleet (a flag to be used by civilians on ships only), but it was only used for 8 years. In 1978, the ensign was chosen as the sole national flag, and it is now used by everyone on land and sea as the flag of Greece.
It is sometimes known in Greece as the blue-white, in Greek Γαλανόλευκη (Galanólefki) or Κυανόλευκη (Kyanólefki).

G Collingridge and WC Piguenit, 'Arthur Range', 1888, (Tasmaniana Library, SLT)
Although not the highest mountain in Tasmania, Federation Peak (1224m) is a difficult climb that for decades resisted every challenger. Despite many attempts, this jagged fang of quartzite at the eastern end of the Arthur Ranges was not climbed until 1949.
Sprent referred to it as 'The Obelisk' when he viewed it from Mt Picton. Paintings of the peak by Piguenit on his way to Port Davey spread its fame further. TB Moore applied its name in 1901, honouring the Federation of the Australian States. In 1905, Richard Geeves penetrated as far as Lake Geeves under the southern cliffs of Federation Peak. Several unsuccessful attempts in the 1920s followed.
Persistent summer exploratory work after the Second World War paved the way for attempts on the final summit block in the late 1940s. Four members of a larger party from the Geelong College Exploration Society, led by John Bechervaise, climbed the peak in January 1949. Bechervaise acknowledged advice given by members of the Hobart Walking Club, who had done so much of the exploratory work. His party used ropes to climb the gully explored two years earlier by Leo Luckman, Bill Jackson and Nancy Shaw when severe weather had turned them back 60 metres from the summit.

The following example demonstrates how to do this:
DateTime a = new DateTime(2010, 05, 12, 13, 15, 00);
DateTime b = new DateTime(2010, 05, 12, 13, 45, 00);
When executed this prints "30" since there is a 30 minute difference between the date/times.
The result of DateTime.Subtract(DateTime x) is a Timespan object which gives other useful properties.
share|improve this answer
You want TotalMinutes, not Minutes - the latter returns the minute component of the TimeSpan, e.g. 10 in 1:10:32 – Ben M May 12 '10 at 17:13
this is what i want – MarsMan May 12 '10 at 17:19
To display the difference, do something like this:Console.WriteLine((a - b).ToString(@"hh\:mm\:ss")). See: MSDN Custom TimeSpan Format – ishmael Nov 5 '12 at 20:07

You want the TimeSpan struct:
TimeSpan diff = dateTime1 - dateTime2;
There are various methods for getting the days, hours, minutes, seconds and milliseconds back from this structure.

What you need is to use the DateTime classs Subtract method, which returns a TimeSpan.
var dateOne = DateTime.Now;
var dateTwo = DateTime.Now.AddMinutes(-5);
var diff = dateTwo.Subtract(dateOne);
var res = String.Format("{0}:{1}:{2}", diff.Hours,diff.Minutes,diff.Seconds));

The way I usually do it is subtracting the two DateTime and this gets me a TimeSpan that will tell me the diff.
Here's an example:
DateTime start = DateTime.Now;
// Do some work
TimeSpan timeDiff = DateTime.Now - start;

You need to use a TimeSpan. Here is some sample code:
TimeSpan sincelast = TimeSpan.FromTicks(DateTime.Now.Ticks - LastUpdate.Ticks);

Or just TimeSpan sincelast = DateTime.Now - LastUpdate; – Ben M May 12 '10 at 17:17
Thanks for the tip. I had no idea you could do it that way. – Jason Webb May 12 '10 at 18:06

IF they are both UTC date-time values you can do TimeSpan diff = dateTime1 - dateTime2;
Otherwise your chance of getting the correct answer in every single possible case is zero.

11.5. Indexes on Expressions
This query can use an index, if one has been defined on the result of the lower(col1) operation:
CREATE INDEX test1_lower_col1_idx ON test1 (lower(col1));
As another example, if one often does queries like this:
then it might be worth creating an index like this:
The syntax of the CREATE INDEX command normally requires writing parentheses around index expressions, as shown in the second example. The parentheses may be omitted when the expression is just a function call, as in the first example.
Index expressions are relatively expensive to maintain, since the derived expression(s) must be computed for each row upon insertion or whenever it is updated. Therefore they should be used only when queries that can use the index are very frequent.

Two New Apps Boost Planting and Harvest Analysis
Nov 15, 2012
To some extent, smartphones are only as smart as the apps they contain. Ag PhD is attempting an IQ boost through the release of two new apps to help farmers more easily analyze planting populations and losses at harvest. The apps, Planting Population Calculator and Harvest Loss Calculator, were created thanks to a Case IH sponsorship and are available for iPhone and Android devices.
"I'm using both of these apps already on my farm, and we feel many other farmers will benefit from them, too," says Brian Hefty, co-host of Ag PhD.
The calculators are pretty straightforward and simple to use. The Harvest Loss Calculator lets you select from soybeans, corn, wheat, sorghum, barley or oats. From there, you count the number of seeds or kernels left on the ground in a square foot. Then, you enter in that number, along with seeds per pound and current crop price, and the app calculates the value of the crop that didn't quite make it into the combine.
"With commodity prices for so many crops at record levels, even the loss of a single bushel per acre over an entire farm can translate to thousands of dollars of lost revenue," Hefty says.
The Planting Population Calculator is another easy-to-use tool. Before planting, farmers can determine optimum in-row spacing between seeds based on row width and desired plant population. After planting, farmers can "ground truth" their results by selecting a row length, counting the number of plants within that distance and entering in their row spacing.
The apps are free and ready for download from the Apple iTunes Store and Google Play.

Is there a way one could bend an object, like a cylinder or a plane using OpenGL?
I'm an OpenGL beginner (I'm using OpenGL ES 2.0, if that matters, although I suspect, math matters most in this case, so it's somehow version independent), I understand the basics: translate, rotate, matrix transformations, etc. I was wondering if there is a technique which allows you to actually change the geometry of your objects (in this case by bending them)?
Any links, tutorials or other references are welcomed!

What you'd need to do to "bend" an object is to apply some appropriate combination of translation/rotation/scaling to only some subset of the vertices of the object in question -- probably weighting that transformation accordingly.
Doing this is a pleasant-looking fashion will necessitate using more vertices than may be otherwise strictly necessary to describe the original mesh. For example, a simple cylinder may only have vertices at either end, but if you want that cylinder to bend in the middle, you'll need vertices there as well.
If all you are interested in is very specific, one-off deformations of very simple shapes (like your aforementioned plane) you could probably just do this manually. For example, decide on the "bend axis" for your plane and compute appropriate transformations for each row of plane vertices to achieve the appropriate rotation about that bend axis depending on their distance from it, and then apply that to the geometry (possibly on the CPU as it would be the most straightforward, at least initially). But such a technique would not scale well and would be very tedious.
Since it can be so cumbersome to correctly figure out how to weight a transformation to each individual vertex in a set to achieve the desired deformation (especially for more practical and complicated objects), many games use a technique called skeletal animation. At a high level this involves associating a separate set of geometry (the "skeleton") with your mesh. That geometry represents the bones of your object, and you define (often in modeling tools) a mapping between vertices of the real model and the bones of the skeleton -- which bones are associated with each vertex, and how much that bone affects the deformation of that vertex. Then the skeleton is animated directly, and the animation is transferred to the real model via the relationship between the bones and their vertices.
Typically in this technique, the mapping between skeleton and real mesh is defined at asset production time. The animations can also be built then, or they can be built procedurally at runtime. The application of the animation transformations to the real mesh occurs at runtime. Generally no new vertices are generated at runtime, which means the range of good-looking deformations is implicitly fixed in the mesh when it is originally created.
In theory, one could also apply tessellation and subdivision to the mesh at runtime based on analysis of the transformations in the animation, and thus produce the appropriate vertices to create an animation that was not necessarily planned for. I'm not aware, offhand, of any papers on this subject.

For the actual math of warping, this can get very complicated, why don't you start here?.
I'll now talk about how you can apply this, assuming you've already got the math for how you will do your deformations down.
2 ways:
1) Every frame, visit every vertex in the cylinder model and offset it in some way.
2) Offset the vertices in the vertex shader as you are rendering. OpenGL ES 2.0 supports vertex shaders. So you're in luck, in a way.
Do you want to only warp the object as it appears on the screen, or do you want to warp the object so every object in the game knows that it has been deformed?
If you warp the object in the vertex shader, then that happens only immediately prior to display/rasterization, so this means none of the game objects will know about the deformation. This is fine if you're simply making a screen saver, or if the deformations are so small that they have no impact on the collidable shape of the object.
When you warp the geometry in the vertex shader __the original vertices of the model actually don't move__, (they only appear to move).
Deformation in vertex shader
non deformed
This is from chapter 6 of the cg tutorial, (program #14).
The shader code to produce this deformation is something like
// choose a displacement amount
float displacement = scaleFactor * 0.5 * sin(position.y * frequency * time) + 1 ;
// displace it in the direction of the normal
float4 displacementDirection = float4(normal.x, normal.y, normal.z, 0) ;
// move the vertex
float4 newPosition = position + displacement * displacementDirection ;
// transform (as normal)
oPosition = mul(modelViewProj, newPosition) ;
So you can see, this happens RIGHT BEFORE display (vertex shader happens on GPU) so CPU code has practically no way to access the transformed vertex position (there are ways to send data from the GPU to the CPU (primarily via textures) but we won't go there).

What you're trying to achieve is basically a subset of the topic of mesh deformation. But since you're a begginer, I'm afraid this type of information might be a bit too strange for now. I'll try to lay down the basic notions though.
In order to do this you'll need two things:
 1. Your mesh needs to have enough vertices for you to transform. For instance if it's a plane, you'll need to make sure it's actually created as a sort of grid, with many vertices for you to deform. Same thing with a cylinder. Might be possible to achieve this at runtime with tessellation but I don't know much about the subject.
 2. You need to use a vertex shader to deform the vertices. Basically the vertex shader takes care of calculating the final transformed position of each vertex, so you can take the chance to apply any deformations to them.
I'm not sure how helpful it will be, but take a look at this OpenGL resource, as it seems to be right the sort of thing you need:
Screenshot from that link:
enter image description here
Just saw Josh's reply and I agree, skeletal animation is also a very elegant way to encapsulate this problem, especially when your deformations start becoming more complex and harder to represent mathematically.
But remember, both points above still apply though - you can only deform vertices, so obviously they need to exist in the first place, which is why your mesh needs to have a decent amount of vertex density. And it's usually the vertex shader that drives skeletal animation and does vertex blending and such.
And by the way, you can do these on the CPU too, but nowadays it's usually a better option to do them on the GPU, which is why I put emphasis on the vertex shader, and you should look into it. It's not really all that much harder programwise than doing it on the CPU anyway.

How to insert squared or any other specific symbol on Mac computer?
Even simple operations on a computer can sometimes be frustrating. For example: you may be typing an email and wish to use the squared symbol that you cannot find on the keyboard or within the editor. This particular example is a frequent problem that many people encounter. As it is not a significant issue, there is actually little information on how to find this elusive symbol.
Rather than having to browse through various forums and websites, we describe in this simple guide how to use the keyboard to type special characters.
Table of Contents:
- How to insert various symbols
- How to insert squared symbol in Pages app
- How to insert squared symbol in Mail app
- Video Showing How to insert squared symbol on Mac computer
How to insert various symbols
To begin, we will learn how to insert miscellaneous symbols on a Mac computer through most applications. Some apps include their own editors with an insert symbol function, however, these might not have the symbol you are seeking. As a solution, you can access the Mac OS default symbol list by simply clicking the Control, Command, and Spacebar combination. This shortcut will launch a Character viewer, which includes many different symbols (including the squared symbol). The squared symbol is under the 'Digits - All' section. If you cannot find this category in left sidebar, click the Gear icon to enable it.
How to insert squared symbol in Pages app
In the Pages app, it is easy to access the squared symbol. Enter the number and followed by the '2' digit. For example, 452. Then highlight the '2' by dragging over it, or holding down shift and pressing the arrow left. Click Format in the menu at top of the screen, select Font, and then choose Baseline. Locate Superscript, which changes the '2' into a squared symbol. Beneath Superscript, the Subscript option allows you to enter logarithms.
How to insert squared symbol in Mail app
To enter specific symbols in Messages or Mail applications, the method is similar to that used for the Pages app. Type the text or number, and then add an additional digit '2'. Highlight the '2', click Edit in the menu at the top of the screen and look for Emojis & Symbols (or Special Characters for earlier Mac OS versions). This will open the same Character Viewer window as in the shortcut described above (the shortcut also works here).

The Alternative Health Benefits of Tuning Fork Therapy
Today many people are learning about the tremendous benefits associated with alternative health practices. There are now physicians who embrace alternative health practices and advise patients to consider their benefits. One of them many beneficial alternative health practices is Tuning Fork Therapy.
A tuning fork is a long metal object that has a handle with two long sides that form a U-shape. The U-shaped portions of the tuning fork are called the tines. They are usually constructed with steel or aluminum and when they're hit on an object they vibrate and create a certain pitch. The length of a tuning fork's tines will determine the level of pitch it produces.
Using a tuning fork for therapy consists of hitting it and having it vibrate. It is then put next to a spot on the body that needs treatment. There is a mineral tuning fork that can be used to stimulate the minerals in a person's body. There are also cellulite reduction tuning forks that have been proven to decrease cellulite. A crystal resonator tuning fork can increase the therapeutic strength of crystals with its vibration. A variety of tuning forks can be used for many different types of therapy.
In an article by Alan Sales called "Tuning Forks for Healing Therapy" he explains some of the health benefits of using tuning forks for therapy.
"In the case of tuning fork therapy a beneficial process of resonance occurs. This means that if the frequency measured in vibrations per second (vps) is applied by focusing the sound generated by tuning forks on various parts of the body, it can help to establish a new pattern of balance, erasing the detrimental patterns caused by the negative resonance pattern of ill health."
The article also sites documented cases of people who experienced healing as a result of using tuning forks for therapy.
To see the variety of tuning forks utilized during therapy and learn about the many health benefits contact Tools for Wellness.

The same beds of chalk are also found along the coast of France on the other side of the English Channel. The chalk beds extend inland across England and northern France, being found as far north and west as the Antrim Coast and adjoining areas of Northern Ireland. Extensive chalk beds are also found in North America, through Alabama, Mississippi, and Tennessee (the Selma Chalk), in Nebraska and adjoining states (the Niobrara Chalk), and in Kansas (the Fort Hayes Chalk) (Pettijohn, 1957).

I'm in a rush, but here's a hint:
EDIT: Now that I have more time, let me see if I can explain this better.
Let's begin by thinking of the circle as a paramaterized curve. In particular, let's consider parameterizing $S^1$ as $\gamma(t)=e^{2\pi it}$ for $t=[0,1]$. The curve $\gamma$ can be thought of as traversing the unit circle once, counterclockwise. While this parameterization will not really make any of our work any easier, it will at least make it clear that the statement is true.
Ok, so note then that if $f:z\mapsto z^n$ is the $n^{\text{th}}$ power map, then we can get a handle of what $f$ does to $S^1$ by seeing how the map $f\circ \gamma$ works--for ease of notation let's call $f\circ\gamma=h$. Now, just unraveling this, we see that, by definition, $h$ is a parameterization of $S^1$ given by $h:[0,1]\to S^1:t\mapsto e^{2\pi i n t}$. Now, the important thing to notice about $h$, is that while $\gamma$ traversed $S^1$ once, we've (in essence) "sped up" so that in our allotted time of $[0,1]$ we actually round the circle $n$ times. In particular, we see that we round the circle once in the interval $[0,\frac{1}{n}]$, again in the interval $[\frac{1}{n},\frac{2}{n}]$, and in general, once in the interval $[\frac{m}{n},\frac{m+1}{n}]$ with $m\in\{0,n-1\}$. Moreover, if we restrict to open subsets of each of these intervals, our map is a homeomorphism onto its image. Thus, we see that, at least intuitively, $h$ does cover $S^1$ "$n$-times".
Now, let's see what happens if we pick a point $p_0\in S^1$ and start looking at neighborhoods around it, and in particular, how about we consider $1\in S^1$. Now, while there are tons of neighborhoods, it makes sense to, if we are going to prove that $f$ is a covering map, restrict our attention to neighborhoods of $p_0=e^{\frac{\pi i}{3}}$ that "come" from $f$, or in our case $h$. In particular, we note that $p_0=h\left(\frac{1}{12n}\right)$. So, a good way to pick a neighborhood of $p_0$ would be to look at the image under $f$ of a neighborhood of $\frac{1}{12n}$--let's say we look at $\left(\frac{1}{13n},\frac{1}{11n}\right)$. Now, this is all valid since we know that on open subsets of each of our subintervals $[\frac{m}{n},\frac{m+1}{n}]$ the map $h$ is a homeomorphism so that $U=h\left(\frac{1}{13n},\frac{1}{11n}\right)$ really is a neighborhood of $p_0$
Now, that we have a very nice neighborhood of $p_0$, let's try to verify the conditions on $f$ that make it a covering map. Let's look at $f^{-1}(U)$. Well, let's actually being by looking at $h^{-1}(U)$, because this is easy to get a handle on. Namely, we know that $h$ just wraps around $S^1$ $n$-times and it will covering $U$ precisely during the time intervals in each interval $[\frac{m}{n},\frac{m+1}{n}]$ that "act like" $\left(\frac{1}{13n},\frac{1}{11n}\right)$. It is not hard to see that each of these subintervals are just going to be of the form $\left(\frac{1}{13n}+\frac{m}{n},\frac{1}{11n}+\frac{m}{n}\right)$ for $m\in\{0,\cdots,n-1\}$. So, now that we have a handle on what $h^{-1}(U)$ looks like, we can easily deal with $f^{-1}(U)$ by just "pushing forward" by $\gamma$. Namely, $f^{-1}(U)$ will just be the union of the sets $\gamma\left(\frac{1}{13n}+\frac{m}{n},\frac{1}{11n}+\frac{m}{n}\right)$ for each $m\in\{0,\cdots,n-1\}$ (where on the circle are these regions?). Moreover, it's clear that each of these intervals are disjoint, because $\gamma$ acts (except for the endpoints, which we aren't worrying about) injectively. Thus, we see that $f^{-1}(U)$ is a disjoint union of $n$ open subsets $\gamma\left(\frac{1}{13n}+\frac{m}{n},\frac{1}{11n}+\frac{m}{n}\right)$ of $S^1$. Moreover, since the action of $f$ on each of these subsets is just $h$ on the intervals $\left(\frac{1}{13n}+\frac{m}{n},\frac{1}{11n}+\frac{m}{n}\right)$ we know that $f$ restricted to each of these maps is a homeomorphism. Thus, we see that the covering map condition is at least at the point $p_0$.
Now, I went into way too much detail, and I'm sure you got the point half-way through, but I hope that was able to help, and I hope you can generalize this to prove that $f$ is a covering map!
