How fast should a wet dog rotate its body to dry its fur?
Taken from http://www.technologyreview.com/blog/arxiv/25910/. Interesting read.
It's a question that many dog owners will have spent sleepless nights pondering. How rapidly should a wet dog oscillate its body to dry its fur?
Today we have an answer thanks to the pioneering work of Andrew Dickerson at the Georgia Institute of Technology in Atlanta and a few buddies. But more than that, their work generates an interesting new conundrum about the nature of shaken fur dynamics.
Dickerson and co filmed a number of dogs shaking their fur and used the images to measure the period of oscillation of the dogs' skin. For a labrador retriever, this turns out to be 4.3 Hz.
They then created a simple mathematical model of what's going on. They reasoned that the water is bound to the dog by surface tension between the liquid and the hair. When the dog shakes, centripetal forces pull the water away. So for the water to be ejected from the fur, the centripetal force has to exceed the surface tension.
This model leads to an interesting prediction. If the animal has a radius R, the shaking frequency must scale with R^0.5. That makes sense, smaller animals will need to oscillate faster to generate forces large enough to dry themselves.
To find out whether that applies in nature, Dickerson and pals studied films of various animals of different sizes. They found that a mouse shakes at 27 Hz, a cat at about 6 Hz while a bear shakes at 4Hz. "Shake frequencies asymptotically approach 4Hz as animals grow in size," they conclude.
But taken together the best fit for this data is not R^0.5 as predicted. Instead the universal rule for shaken fur is that the frequency increases with R^0.75.
Clearly, their model misses some important correction factor. Dickerson and co make one suggestion. In their model, the radius is the distance from the centre of the animal to its skin. Perhaps the fur makes a difference, they say in a video intended for the 2010 APS Gallery of Fluid Motion.
Maybe. It certainly gives paws for thought (ahem).
Further ideas in the comments section please.

Righteous Among the Nations: Muslims Who Saved Jews from Holocaust
This story got published in Huffington Post and I couldn’t resist sharing with you all. This is the story of courage, the story of Besa… and more importantly, the story of standing for the right thing. (http://www.huffingtonpost.com/2010/11/01/project-explores-muslims-_n_777257.html)
By Tim Townsend
St. Louis Post-Dispatch
ST. LOUIS (RNS) In 2003, Norman Gershman was looking for some of the righteous.
What he found astonished the investment banker-turned-photographer, and led him toward a project now on display in a St. Louis synagogue.
The Righteous Among Nations are gentile rescuers who make up "a small minority who mustered extraordinary courage to uphold human values," according to Yad Vashem, Israel's Holocaust memorial museum.
They are, the museum says, "the few who helped Jews in the darkest time in their history."
Gershman's story begins during the Holocaust and involves Albanian Muslims -- villagers, peasants and farmers -- who risked their lives and the lives of their families to shelter Jews fleeing Nazi Germany.
Italy invaded Albania in 1939 and occupied the country until the overthrow of Benito Mussolini in 1943. Germany then took over the Albanian occupation. Before the war, Gershman estimates from his research, only about 200 Jews lived in Albania, a country that is about 70 percent Muslim.
During the years of occupation, 10 times as many Jews streamed into Albania to escape persecution from Poland, Yugoslavia, Czechoslovakia, Greece and Italy. Gershman says it was the only country in Europe where the Jewish population grew by the end of the war.
Most of the hidden Jews either fled to Israel or back to their native countries after the war. Albania's postwar communist regime made it impossible for the Jews who had been hidden to stay in touch with the Albanian Muslims who had provided shelter.
In 2003, New Jersey native Gershman heard hints of the story and began doing research, eventually traveling to Albania to begin interviewing those Muslims who took part and who were still alive. Gershman said it wasn't just Muslim families who shielded Jews from the Nazis, but also Orthodox and Catholic families.
All of them were motivated by an Albanian code of honor called "besa," a concept that can be translated into "keeping the promise," Gershman says. The Albanian villagers were motivated to risk their lives by the simple concept of helping one's neighbor.
"We chose to focus on the Muslims because, who ever heard of Muslims saving Jews?" Gershman said in a telephone interview from Israel, where he is at work on his next project.
Gershman's research eventually led to an exhibit of his photographs, "Besa: A Code to Live By," which opened recently at Congregation Temple Emanuel, and a book, Besa: Muslims Who Saved Jews in World War II.
The exhibit makes the case that the Muslim Albanian villagers who sheltered Jews from deportation to concentration camps did so from a sense of religious obligation.
"Besa is a cultural idea, but for the Muslims in Albania it was ingrained in their faith as well," Gershman said.
Ahmet Karamustafa, professor of history and religious studies at Washington University, said saving a life is a universally acknowledged Muslim value.
Protecting a life, Karamustafa said, "has always ranked at the very top of moral and legal categories articulated by legal and theological scholars in Islam."
The exhibit has been traveling the world since 2006, opening in Yad Vashem in Israel, the United Nations in New York, and synagogues, mosques, college campuses and Holocaust museums from Turkey to El Paso, Texas.
The exhibit of 30 photographs includes one of Lime Balla, born in 1910, who told Gershman that a group of 17 Jews came from the capital city of Tirana to her village of Gjergi in 1943 during the holy month of Ramadan.
"We divided them amongst the villagers," Balla said, according to Gershman. "We were poor. We had no dining table, but we didn't allow them to pay for food or shelter. We grew vegetables for all to eat. For 15 months, we dressed them as farmers like us. Even the local police knew."
David Sherman, president of Temple Emanuel, said the synagogue "decided it could be an opportunity to educate the public about this piece of history that was a model of dialogue and tolerance."
The synagogue's rabbi, Justin Kerber, said one of the Reform congregation's goals with the exhibit is to combat a common depiction of the modern relationship between Jews and Muslims.
"There's so much coverage about Muslim-Jewish strife and conflict," Kerber said. "It's important to tell people that's not the whole story, and these are examples of Muslim-Jewish respect, tolerance and love. This was a good opportunity for us to be part of that conversation."
Study: Alcohol 'most harmful drug,' followed by crack and heroin
Below article is published in CNN Health… thought of sharing with you all.
Note: This is not my justification for not consuming alcohol. I have always maintained, I don’t consume alcohol because it is strictly prohibited in Islam.
http://www.cnn.com/2010/HEALTH/11/01/alcohol.harm/index.html?hpt=C2
London, England (CNN) -- Alcohol ranks "most harmful" among a list of 20 drugs, beating out crack and heroin when assessed for its potential harm to the individual imbibing and harm to others, according to study results released by a British medical journal.
A panel of experts from the Independent Scientific Committee on Drugs weighed the physical, psychological, and social problems caused by the drugs and determined that alcohol was the most harmful overall, according to an article on the study released by The Lancet on Sunday.
Using a new scale to evaluate harms to individual users and others, alcohol received a score of 72 on a scale of 1 to 100, the study says. It was compared to 19 other drugs using 16 criteria: nine related to the adverse effects the drug has on an individual and seven on its harm against others.
That makes it almost three times as harmful as cocaine or tobacco, according to the article, which is slated to be published on The Lancet's website Monday and in an upcoming print edition of the journal.
Heroin, crack cocaine and methamphetamine were the most harmful drugs to individuals, the study says, while alcohol, heroin and crack cocaine were the most harmful to others.
In the article, the panelists said their findings show that Britain's three-tiered drug classification system, which places drugs into different categories that determine criminal penalties for possession and dealing, has "little relation to the evidence of harm."
Panelists also noted that the rankings confirm other studies that say that "aggressively targeting alcohol harms is a valid and necessary public health strategy."
The Lancet article was co-authored by David Nutt, a professor and Britain's former chief drug adviser, who caused controversy last year after he published an article saying ecstasy was not as dangerous as riding a horse.
"So why are harmful sporting activities allowed, whereas relatively less harmful drugs are not?" Nutt wrote in the Journal of Psychopharmacology. "I believe this reflects a societal approach which does not adequately balance the relative risks of drugs against their harms."
Nutt later apologized to to anyone offended by the article and to those who have lost loved ones to ecstasy. He said he had no intention of trivializing the dangers of the drug and that he only wanted to compare the risks.
In the article released by The Lancet on Sunday, ecstasy's harmfulness ranking -- 9 -- indicates it is only one-eighth as harmful as alcohol.
The study was funded by the London-based Centre for Crime and Justice studies.

Karvachauth – How does fasting by wife increase the life expectancy of her husband?
In India, more specifically among the followers of a religion called Santana Dharma (popularly known as Hinduism), wives fast a day every year for the increase in lifespan of her husband. This custom is referred as ‘Karva-Chauth’. In this blog post, I would make an attempt to list out the scientific reasons behind this custom i.e. how does fasting by wife increase the life expectancy of her husband?
Foundations of Santana Dharma are deeply rooted in the advance scientific culture that once existed in ancient India. However, due to decline of science in India, several customs of Santana Dharma have become blind beliefs. Also, over the years, several customs have gone through unscientific modifications resulting in ambiguity. Nevertheless, there still remains several customs that reflect the rich scientific understanding of ancient Indians. Let us now, understand the scientific explanation for Karva-Chauth custom.
Fasting for a limited duration (~12 hours) has scientifically proven to have positive results on both adult men and women. Various publications on this can be found in the literature. Following are the core advantages highlighted by several researchers
- 1. Fasting results in biological process called ‘autolysis’, which is breaking down of fat stored in the body in order to produce energy. Autolysis leads to higher detoxification, a normal body process of eliminating or neutralizing toxins through body organs such as kidneys, liver, skins, etc. In layman terms, detoxification is equivalent to body cleaning.
- 2. It is proven that, during fasting, healing process occurs faster within the body due to higher efficiency in protein synthesis resulting in healthier cells, tissues and organs. (This is also proven in several animals. When animals get wounded, they stop consuming food to increase the rate of healing.)
Note: Prolonged fasting for more than 24 hours can be harmful to health. In above paragraph, fasting refers to ‘not consuming any food for duration of approx. 12 hours.
Now, that explains why fasting can be helpful to human beings. Better health is equivalent to better life expectancy. But the above scientific explanation doesn’t explain why fasting by a wife would result in higher life expectancy of her husband. To understand this, let us look at some recent biomedical results.
According to recent research done by Giana Angelo and Marc R.Van Gilst, female worms when subjected to fasting (starvation) have shown increase in their life-expectancy and more remarkably have shown increase in their reproductive longevity. In a paper titled ‘Starvation protects Germline stem cells and extends reproductive longevity in C. elegan’ published in Science journal highlights these findings.
“The study of starvation-resistant biological programs has elucidated numerous mechanisms influencing aging. Here we present the discovery and characterization of starvation-induced adult reproductive diapause (ARD) in Caenorhabditis elegans. ARD differs from the C. elegans dauer diapause in that it enables sexually mature adults to delay reproductive onset 15-fold and extend total adult life span at least threefold. The effectiveness of ARD requires apoptotic death of the entire germ line, except for a small population of protected germline stem cells (GSCs). When feeding is resumed, surviving GSCs regenerate a new germ line capable of offspring production near the level of non-starved animals. The starvation-sensing nuclear receptor NHR-49 is required for ARD entry and recovery. Our findings establish mechanisms for preserving stem cell potency and reproductive potential during prolonged starvation.”
Dr. Van Gilst goes on to quote, “Many paradigm-shifting discoveries in C. elegans have since been replicated in humans. Therefore, the idea that our findings will be relevant to human reproduction is a possibility that certainly needs exploration” and “If such a process exists in humans, it likely evolved to help our ancestors preserve fertility during periods of famine or food shortage. We certainly don't have a prescription for famine. Consequently, our study should not be used to promote potentially dangerous interventions such as severe caloric restriction and starvation as a means to restore a woman's fertility”
If we assume that, fasting indeed improves the reproductive longevity and life expectancy among women, it still doesn’t prove ‘fasting by wife increases the life expectancy of men’. For this, we need to look at another important biomedical result.
According to the research done by Davey Smith, S. Frankel and J. Yarnell from University of Bristol, sexual activity seems to have a protective effect on men’s health. As per their research paper titled “Sex and death: are they related? Findings from the Caerphilly cohort Study”,
“Mortality risk was 50% lower in the group with high orgasmic frequency than in the group with low orgasmic frequency, with evidence of a dose-response relation across the groups. Age adjusted odds ratio for all-cause mortality was 2.0 for the group with low frequency of orgasm (95% confidence interval 1.1 to 3.5, test for trend P = 0.02). With adjustment for risk factors this became 1.9 (1.0 to 3.4, test for trend P = 0.04). Death from coronary heart disease and from other causes showed similar associations with frequency of orgasm, although the gradient was most marked for deaths from coronary heart disease. Analysed in terms of actual frequency of orgasm, the odds ratio for total mortality associated with an increase in 100 orgasms per year was 0.64 (0.44 to 0.95).”
Now, let’s combine the two results and understand the bigger picture. It can be summarized as follows,
- · Fasting increases reproductive longevity and female lifespan
- · Higher Reproductive longevity implies potential for more sexual activity by women during lifespan.
- · Higher Sexual activity has protective effect on men’s health, increasing the life expectancy.
As per Karva-chauth custom in India, a wife fasts for the increase in life expectancy for her husband. Scientifically, her fasting leads to higher reproductive longevity, leading to higher sexual activity during her lifespan. And since Santana Dharma strictly prohibits adultery, husband is the only option for sexual activity for married woman; hence her increase in sexual activity is directly proportional to her husband’s sexual activity, which in turn means, husband is going to have higher life expectancy due to increase in sexual activity.
The above scientific explanation can be easily tested on animals and humans, hence one can safely say, ancient Indians could have conducted scientific experiment and come to the conclusion that, by ‘fasting by wives would result in higher life expectancy for their husbands’. Note, this result is statistical in nature, individual cases might vary. But overall, it would increase the life expectancy.
Now, that explains why, ancient Indians started the custom of Karva-Chauth.
