Two astronauts have performed a spacewalk, or EVA, to replace a depleted nitrogen tank in the Integrated Truss Structure of the International Space Station. The Space Station’s Nitrogen Tank Assembly (NTA), was successfully replaced with a new one, launched aboard Space Shuttle Atlantis, which is currently visiting the station, on mission STS-122. The old tank will be returned to Earth aboard the Shuttle. The NTA forms part of the Space Station’s cooling system.

The spacewalk was successful, and the primary task of changing the tank was completed ahead of schedule, allowing the astronauts to perform several secondary tasks, which included the installation of thermal covers on the newly installed Columbus module, and inspection of micrometeoroid shields on the Destiny module.

American astronaut Rex Walheim and German astronaut Hans Schlegel, both of the STS-122 crew, left the ISS Quest airlock at 14:27 GMT, and re-entered it at 21:12, after six hours and 45 minutes of extra-vehicular activity. This is the 103^rd spacewalk to be made as part of the International Space Station programme, and the second of three planned for the STS-122 mission.

Meanwhile, NASA have announced that the STS-122 mission has been extended by one day. Landing is now scheduled for next Wednesday, at 13:59 GMT. The extension will give the astronauts extra time to finish activating the Columbus module, a process which has been delayed due to computer problems aboard the module.

Hundreds of thousands of air travelers had their travel plans disrupted in Europe by volcanic ash from the Eyjafjallajökull eruption.

Tens of thousands of air travelers were stranded when all flights into and out of the United Kingdom were grounded, as it became one of the first nations to be affected. The grounding was even more extensive than that following the September 11 attacks of 2001 when only trans-Atlantic flights were canceled.

Eurocontrol released a statement saying “…most air traffic in the United Kingdom, Ireland, Denmark, Norway and Sweden is suspended.”

The grounding is because the volcanic ash drawn into the jet stream is of a particle size which allows it to remain aloft in the atmosphere. Ingestion of this foreign matter, because of its distribution, would lead to flame outs in all aircraft engines. The composition of the ash also means that it would first melt into glass if it were to enter the engine of an aircraft before solidifying again as it cooled. This could lead to damage to the compressors and fan blades, which would make it impossible to restart the engines, even if the aircraft were to exit the cloud.

The current contingency is informed by the experience of British Airways Flight 9, which on June 24, 1982 suffered just such complete engine flame outs when it flew through the plume of Mount Galunggung in Indonesia. In that case, the flight crew after many efforts was able to restart the engines, though one failed shortly after, and the aircraft landed without casualties.

The UK National Air Traffic Services (NATS) has stated that “restrictions will remain in place in UK controlled airspace until 1300 (UK time) tomorrow, Friday 16 April, at the earliest,” and that “We will review further Met Office information and at 0230 (UK time) tomorrow we will advise the arrangements that will be in place through to 1800 (UK time) tomorrow.” The NATS statement concluded “…the situation cannot be said to be improving”.

In addition to Northern Europe, the ash is drifting south; Berlin and Hamburg airports in Germany are closed, and airports in the Netherlands, Belgium and Northern France are described as now being closed or closing. Some flights from Spain and Portugal, together with upwards of 4,000 flights across Northern Europe, have been affected, and the knock-on effect of aircraft and crews out of position could disrupt air travel worldwide for up to 72 hours.

One affected group are British musicians booked to play at this weekend’s Coachella Festival in California. Amongst those stranded are Frightened Rabbit, Gary Numan, The Cribs and Bad Lieutenant.

Jack A. Weil, founder and CEO of Rockmount Ranch Wear died on August 13 at the age of 107 in Denver, Colorado. He was the oldest working CEO in the United States. He was also known as “Papa Jack”.

He was born on March 28, 1901 in Evansville, Indiana. In 1946, Weil rented a space at 1626 Wazee Street in Denver and set about trying to create a fashionable yet practical identity for the western ranchers of the region.

Weil was well-known for coining the phrase “The West is not a place, it is a state of mind.” He was the first person to put snaps on Western shirts, patented the saw-tooth pocket design seen on many Western shirts, and was credited with inventing the bolo tie.

In 2001, he told Associated Press, “I learned fast you can’t sell to cowboys; they have no money. You have to appeal to the cowboy in everyone and sell to them.”

Among his customers were Ronald Reagan, Bob Dylan, Eric Clapton and Nicholas Cage. More recently, Rockmount shirts were worn by the late Heath Ledger and Jake Gyllenhaal in the 2005 Academy Award-nominated movie, Brokeback Mountain.

Weil’s wife, Beatrice Baum, died in 1990, followed by his son Jack B. in January 2008.

“I never wanted to be the richest man in the cemetery,” he told his grandson and current president of the family business.

Former Australian Prime Minister John Howard supported the launch of a new book “How to Get Expelled from School: A Guide to Climate Change for Pupils, Pundits and Parents”, authored by geology professor Ian Plimer. The book includes 101 questions for students to use to challenge their climate science teachers.

The book follows Professor Plimer’s 2009 “Heaven and Earth”. Professor Plimer said the previous book received feedback from parents concerned about education. This prompted him to address the next book to children. He said, “After Heaven and Earth came out I had many parents write to me and say, ‘Look, what do we do, our kids are being fed activism. I want my children to have the basics of scientists, I don’t want to be fed activism'”.

Mr Howard advocated emissions trading in 2007. He says he considered it feasible if the rest of the world acted too, otherwise to introduce carbon trading plans would risk Australian industries. “I proposed an emissions trading scheme and some people say, ‘Well why on earth did you do that?’ [It was] predicated on the rest of the world moving in the same direction and also predicated on a structure that would preserve the international competitiveness of those industries that gave our country a competitive trade advantage, it could do no harm”, he explained. “[It’s] hard to understand how we would do anything to put” Australia’s competitive advantage due to natural resources “at risk. The reality is we are doing that at the moment. The carbon tax is not being replicated in other countries.”

Professor Ian Enting, complex system scientist at the University of Melbourne, said the book includes scientific errors and insufficient references. Margaret Watts, president of the Science Teachers’ Association of New South Wales, said the educational bias claim is mistaken. “What science teachers do”, she said, “is put all of the facts, pro and con, against any topic, whatever it is, and show the children how to work through the evidence”.

Professor Plimer said of the 101 questions in his book, “They’re questions that kids should be asking of teachers, because if the teacher can answer it means they might know something about the subject. If they can’t, or start to promote ideology, it shows that our schools have been captured. Parents are telling me that schools have been captured by a lot of activists and kids are being fed stuff that is not relevant to the real world.”

Creekstone Farms Premium Beef, an organic meatpacking company based in Arkansas City, Kansas, filed a lawsuit against the U.S. Department of Agriculture (USDA) for what the company claims is threats by the USDA that it would face prosecution if it proceeds with plans to test nearly 100% of its beef for Bovine spongiform encephalopathy, also known as mad cow disease or BSE.

The USDA position is that allowing any meatpacking company to test every cow would undermine the agency’s official position, a position that holds to random testing as a scientifically adequate measure to assure safety. It also claims that 100% testing does not ensure food safety because the disease is difficult to detect in younger animals.

The USDA currently tests about 1% of cattle slaughtered in the U.S. The USDA’s objection is believed to be the result of pressure from larger meatpacking operations. In 2004, the president of the National Cattlemen’s Beef Association told the Washington Post that “If testing is allowed at Creekstone, we think it would become the international standard and the domestic standard, too.” Creekstone Farms says tests cost about $20 per animal, increasing the cost of beef by about 10 cents per pound.

Tuesday, March 29, 2005A team of Australian surgeons yesterday reattached both hands and one foot to 10-year-old Perth boy, Terry Vo, after a brick wall which collapsed during a game of basketball fell on him, severing the limbs. The wall gave way while Terry performed a slam-dunk, during a game at a friend’s birthday party.

The boy was today awake and smiling, still in some pain but in good spirits and expected to make a full recovery, according to plastic surgeon, Mr Robert Love.

“What we have is parts that are very much alive so the reattached limbs are certainly pink, well perfused and are indeed moving,” Mr Love told reporters today.

“The fact that he is moving his fingers, and of course when he wakes up he will move both fingers and toes, is not a surprise,” Mr Love had said yesterday.

“The question is more the sensory return that he will get in the hand itself and the fine movements he will have in the fingers and the toes, and that will come with time, hopefully. We will assess that over the next 18 months to two years.

“I’m sure that he’ll enjoy a game of basketball in the future.”

The weight and force of the collapse, and the sharp brick edges, resulted in the three limbs being cut through about 7cm above the wrists and ankle.

Terry’s father Tan said of his only child, the injuries were terrible, “I was scared to look at him, a horrible thing.”

The hands and foot were placed in an ice-filled Esky and rushed to hospital with the boy, where three teams of medical experts were assembled, and he was given a blood transfusion after experiencing massive blood loss. Eight hours of complex micro-surgery on Saturday night were followed by a further two hours of skin grafts yesterday.

“What he will lose because it was such a large zone of traumatised skin and muscle and so on, he will lose some of the skin so he’ll certainly require lots of further surgery regardless of whether the skin survives,” said Mr Love said today.

The boy was kept unconscious under anaesthetic between the two procedures. In an interview yesterday, Mr Love explained why:

“He could have actually been woken up the next day. Because we were intending to take him back to theatre for a second look, to look at the traumatised skin flaps, to close more of his wounds and to do split skin grafting, it was felt the best thing to do would be to keep him stable and to keep him anaesthetised.”

Professor Wayne Morrison, director of the respected Bernard O’Brien Institute of Microsurgery and head of plastic and hand surgery at Melbourne’s St Vincent’s Hospital, said he believed the operation to be a world first.

The sales of the Microsoft Corporation has increased considerably during the latest quarter, having brought more profit than predicted by Wall Street. However, the delay in arrival of the major new products resulted in spoiled financial results.

The quarter that finished in December marked the increase by 6 percent in the Microsoft sales, having reached the revenue of $12.5 billion. The delayed products – the latest versions of Windows Vista and Office 2007 – are to be launched next week.

Microsoft’s video game business grew considerably in the quarter – its revenue increased by 75 percent, to the mark of $2.96 billion. The success of the business is explained by steady sales of its Xbox 360 console and highly demanded games like the critically acclaimed Gears of War at the end of 2006.

The noteworthy results have been gained by Microsoft in selling its server software applied in corporate data centers. It brought the revenue up 17 percent, to $2.85 billion. As for the operating profit, it increased by 35 percent, to over $1 billion. Following the most profitable Windows and Office, the server group, including databases, operating systems, and back-end programs used for e-mail systems, presently represents the third major product line of the Corporation.

Net income witnessed 28 percent decrease, to $2.63 billion to be compared to $3.65 billion dollars during the same period of time the previous year.To solve the problem of the product delay and support the personal computer industry, Microsoft provided free or discount coupons for upgraded versions of Windows Vista and Office 2007. Consequently, PC makers sold new computers during the last period of 2006 promising their customers that they would be able to acquire the new Microsoft products, thus preventing PC sales from standing at still point.

The coupon program was initiated by Microsoft in October with expectations of approximately 1.5 billion dollars in revenue to be deferred. However, with better PC sales Microsoft received the $1.64 billion.Microsoft pays attention towards development of the consumer electronics business. In the end of 2006 the company launched a digital media player called Zune, a product to compete with iPod produced by Apple. However, Microsoft’s section of consumer entertainment and devices is not profitable yet.

As for Microsoft’s on-line business, it also leaves much to be desired, especially considering Internet searches. In the latest quarter there was a decline in the Microsoft’s market share in searching. Still, the company continues to invest into this business segment. The revenue brought by on-line services, including web advertising and search-linked ads, increased by 5 percent in the quarter, to $624 million.

A compilation of brief news reports for Tuesday, December 9, 2008.

The United States media group Tribune Company has filed for bankruptcy protection on Monday as it struggled to sort out its US$13 billion debt. It is the second-largest newspaper publisher in the United States, responsible for the Chicago Tribune and the Los Angeles Times, among others.

The firm has been hit hard by the industry-wide slump in newspaper advert revenues this year. Sam Zell, the billionaire who owns Tribune, took out large loans in order to buy the firm back in June of 2007.

The United States Chapter 11 bankruptcy protection law states that a company can continue trading whilst it sorts out its finances.

The Quebec general election is underway in the Canadian province of Quebec. Premier Jean Charest called the elections, saying he needed a majority to guide Quebec through a period of economic difficulties caused by the worldwide financial crisis.

Polls indicate that the Charest may obtain a majority, with support for his Quebec Liberal Party increasing to 45%, while support for the Parti Québécois remains at around 30%.

The polls will close at 01:00 GMT (20:00 local time), and the results will probably come in soon after that.

The United States government is reportedly close to an agreement for a US$15 billion bailout plan for the country’s three largest auto firms.

According to a draft obtained by the Associated Press, the deal would give loans to Detroit‘s struggling Big Three automobile manufacturers — Ford, General Motors, and Chrysler — but under the condition that the auto industry restructures itself to survive. Another condition is that the incumbent US President, George W. Bush, would appoint an overseer to supervise the effort.

Analysts suggest that the agreement could be signed into law by the end of this week.
