one question on motor winding

k1 is 234.5 for 100% IACS conductivity copper, or 225 for aluminum, based on a volume conductivity of 62%.

For other winding materials, a suitable value of k1 (inferred temperature for zero resistance) shall be used.

How to intrepret " inferred temperature for zero resistance"? Thanks a billio

Hayek, Milton Friedman added to Texas Textbooks

MAJOR VICTORY FOR LIBERTARIANS!!

Thanks to the efforts of the hardright conservative majority on the Texas Board of Education, two Libertarian Giants in Economics will now be studied in State High Schools.

From the NY Times, Justin Wolfers (Freakonomics), "Hayek propped up by Government Intervention", March 15:

How do they plan to rewrite high school economics?

In economics, the revisions add Milton Friedman and Friedrich von Hayek, two champions of free-market economic theory, to the usual list of economists to be studied – economists like Adam Smith, Karl Marx and John Maynard Keynes

Wolfers goes on to heartily approve of Friedman's inclusion, but not necessarily of Hayek. He believes him to be too obscure, based on relatively low amount of Google searches he receives in relation to other better known economists:

Sure, Hayek was an insightful economist. But insisting that high schools teach Hayek is a clear statement of ideology, not of economic science.

Free Market Mojo blogger responds to Wolfers:

Um, what’s the problem? Milton Friedman and Friedrich von Hayek are tremendously influential figures, not just in the field of economics. Can a truly honest study of the past century ignore their contributions to the world? I don’t think so. Mention them and criticize them if you must, but don’t ignore them.

There were other changes of note. Interestingly, the term "capitalism" was replaced in the textbooks by "free enterprise." additionally, early reports from Leftist bloggers had Thomas Jefferson removed from any mention in history books. This is incorrect. Jefferson was removed from only discussions of the enlightenment section not of American history. (Source: Village Voice)

Opposition to Mandatory Seat Belt laws a 10th Amendment issue

by Eric Dondero

Rhode Island is having a big debate right now over toughening the States' seat belt law. Same old story. The Feds are dangling dollars over the heads of Little Rhody legislators if they'd only enact a Primary law enforcement bill. This means cops could stop a non-wearer for no other reason than for violation of the seat belt law.

Of course, it's the Democrats who are proposing the legislation. The bill has been initiated by Rep. Douglas Gablinske.

But surprisingly Gablinske has been receiving a great deal of criticism, from various constituencies.

One of his biggest critics has been his own friend, columnist Jim Baron of Woonsocket. Baron makes a uniquely 10th Amendment argument on the issue.

From The Woonsocket Call, "We don't need a mandatory Seat Belt law" March 14:

Where are the Tenth Amendment people on this? There is a growing movement of folks out there, they seem to be one of the many tributaries to the larger Tea Party movement, who want to re-assert the force and effect of the Tenth Amendment to the U.S. Constitution, which says that any powers not directly granted to the federal government by the constitution, or denied to the states by the constitution are reserved to the states or to the people and the feds should keep their cotton-picking hands off it. (The constitution doesn’t have the cotton-picking part; I added that.)

Well, nowhere in the enumerated powers granted to the federal government does it say anything about seat belt laws. And the Congress knows that because it didn’t pass a seat belt law. No, instead it circumvented the constitution by misusing the public purse to bribe the states to do its bidding by offering them money. Sometimes, Congress does it the other way around, by misusing the public purse to extort states to do its bidding by threatening to withhold funds if they don’t.

The Tea Party movement has cleverly steered clear of social issues. But this is one area that could be considered a social matter - 10th Amendment and Federal Bribery of State Governments - that's a natural for Tea Party involvement.

EUROPEAN UNION: Geert Wilders’ Party of Freedom called "Fascist" for Fiscal Conservatism

Just Released Video... Fireworks fly in the EU...

European Parliament proceedings. The PVV (Party for Freedom), representatives from the Netherlands ask for a general accounting of travel expenses and other questionable expenditures in the budget. They are joined in by members of other parties from other nations seeking more transparency and openess in accounting.

At 3:25 in, the debate becomes heated. A Socialist member yells out that the PVV-ers are "Fascist," for suggesting such an inquiry. The PVV members respond in an animated fashion; a common Dutch hand expression for "screw you."

The female PVV member is Laurence Stassen. She is a former TV news reporter.

There are three PVV members serving in the Euro Parliament out of a total of 761. They are the third largest Dutch delegation.

You can watch a video of Laurence Stassen here. For more info Dutch Party for Freedom (PVV)

The Enduring Mystery of Thalidomide | The Loom

thalidomideIn tomorrow’s New York Times I write about the afterlife of the greatest medical disaster in history. Thalidomide, a drug women took for morning sickness in the late 1950s, caused thousands of devastating birth defects, such as the failure of limbs to develop. Even after the drug was banned, scientists had no idea how it interfered with growing arms and legs. In fact, fifty years later, they’re only just starting to figure it out.

This was a particularly interesting story to write coming after a piece I wrote for the Times last year about normal limb development. Now thalidomide is revealing a new player in the limb development game, a protein that no one knew about when I wrote my 2009 article. In science, very often the only way to understand how something works is to see what happens when it goes wrong.

PS: On Google Books, you can see a 1962 issue of Life with some stunning pictures from the Thalidomide years.

The New John Mackey of Genetics: Linda Avey?

So if Andrew Pollack decides to take a swipe at this fledgling industry, he won’t be the first, or the last. It’s an easy bandwagon to jump on, along with the other nay-sayers, but there’s a growing wave of data-empowered people who won’t bat an eye, and who may just help lead us into a new age of personalized health that Andrew himself may find quite beneficial. Now that’s something to write about.

469473526_06d88612a1Response of brown tree snakes (Boiga irregularis) to human blood

“Ten specimens of Boiga irregularis were presented with clean or bloody tampons. The latter were used by women during menses. Trial duration was 60 sec, intertrial interval was 24 hr, and the dependent variable was rate of tongue flicking (a measure of chemosensory investigation). Bloody tampons elicited significantly more tongue flicking than did control tampons. An additional snake is shown attacking and ingesting a soiled tampon, confirming that chemosensory interest was associated with predatory behavior.”

Bonus figure legend from the main text of the paper (we decided to spare you the actual figure):

“FIG. 1. (A) A brown tree snake investigates a soiled tampon suspended into its cage.
(B) Seconds later the snake bites the tampon. (C) About 2 min following the bite, the
snake is shown with only the string remaining unswallowed. This snake then struck and
swallowed a second soiled tampon.”

That is a model of the USS Enterprise-D from Star Trek: The Next Generation, created using an ion beam that guides vaporized chemicals and deposits them into a given shape. The amazing thing is that this model of the Big Little-E is only 8.8 microns (millionths of a meter) long! For comparison, a human hair is about 50-100 microns across. This image is magnified 5000 times.

I wonder if it comes with a tiny Wil Wheaton, too?

Greeting all,

I know, when power angle is less than 90 degree, the system is stable. When it is more thant 90 degree it is not stable

the power flow formula is as below

P = Vs x Vr x Sin0 / X

Suppose, if we have a sytem with power angle of 30 de

Is Ivory Season Starting, Just as Tuna Season’s Ending? | 80beats

bluefinSushi chefs in Japan are keeping a close eye on Doha, Qatar this week as delegates at the Convention on International Trade in Endangered Species (CITES) debate the future of their beloved bluefin tuna. The fish, a delicacy in Japan that can sell for more than $100,000 apiece, is being overfished, and convention delegates aim to prevent the tuna from becoming extinct altogether. The proposal on the table: A complete ban on international trade of the fish to allow stocks to regenerate.

The bluefin tuna ban was proposed by Monaco, and the vote will probably come up next week. Japan has already dispatched a delegation to Doha with the message that Japan won’t comply with a total ban, and would instead prefer a fishing quota. But quotas have failed to help the depleted bluefin tuna stocks thus far. Japan last year pledged to help meet an accord to slash the total catch in the eastern Atlantic and Mediterranean by 40 percent, although environmental groups charge that such quotas are routinely exceeded [AFP].

The European Union and the United States have come out in support of a total ban, since decades of overfishing has caused the number of bluefin in the Atlantic and Mediterranean to crash by more than two-thirds. Japan, meanwhile, hopes to fend off the ban by enlisting the support of developing nations in Africa and Latin America. Tokyo said that even if a ban is implemented, it could use a treaty technicality to opt out of the agreement by expressing “reservations,” and would then continue to import from other countries.

Meanwhile, at the world’s largest fishing market in Tokyo’s Tsukiji district, bluefish tuna fishermen began collecting signatures to oppose the ban. They said measures to prevent overfishing of the tuna should be implemented instead [The Asahi Shimbun]. Traders also fear a steep price hike for the bluefin, known as “kuro maguro” or black tuna in Japan. A piece of “otoro” or fatty underbelly now costs 2,000 yen (22 dollars) at high-end Tokyo restaurants [AFP].

The other bitter battle being played out at the CITES meeting is Zambia’s and Tanzania’s proposal for a one-time sale of ivory, so that they may clean out their stockpiles of ivory–collected, they say, from elephants who died natural deaths. So far, the proposal has been resisted by countries like Kenya that argue that such sales give cover to poachers who engage in “ivory-laundering,” and would increase poaching in the region.

Zambia and Tanzania both insist that they will funnel the $18.5 million they expect to earn from the sale into conservation efforts, but that claim has been met with skepticism. A recent report in the journal Science revealed a sharp increase in poaching in recent years–with much of the ivory trafficking running through Zambia and Tanzania.

Kenya and its allies have proposed supporting a bluefin tuna ban in exchange for greater protection for the elephants. However, this horse trading is viewed as controversial: Conservationists argue that every proposal should rise or fall on the basic of scientific evidence detailing the possible extinction of individual species, not as part of a political deal [The New York Times].
