Clarke reduces relationship with Bingle to cold, hard stats

Wellington, Mar.19 (ANI): Australian vice-captain Michael Clarke has reduced the break-up of his relationship with Lara Bingle to cold, hard business.

Former captain Ian Chappell had questioned whether Clarke’s return to Australia a fortnight ago had showed the “durability and stability” necessary to be Australian captain.

But in returning to Wellington, Clarke has shown a different side of his personality – the ability to make a decision that counts.

“It was about making a decision at the time and, obviously, I thought I had to go home and do what I had to do, and I did that,” Clarke said.

When asked about the scrutiny that has accompanied his break-up, he said: “We have to accept that and, for me, it was important to do what I had to do in my personal life.”

“And, it”s important to me, like I say now, to be back with my team mates and making sure I”m concentrating on playing a Test match for Australia,” he said without sentiment.

He was faultless yesterday in front of the media, which had been warned not to ask questions about his personal life but launched straight into them.

Clarke was chirpy and forthright, like a burden was now gone.

He has come out a winner and has now returned to the routines of touring life, where he is most comfortable.

“Like I say,” he said, “preparation has been important to me throughout my career and it”s no different now.” (ANI)

Incisionless procedure ‘reverses weight gain after gastric bypass surgery’

Washington, June 30 (ANI): Scientists have offered an incisionless procedure to reverse weight gain after gastric bypass surgery.

To perform the procedure, known as ROSE (Restorative Obesity Surgery, Endolumenal), a small, flexible endoscope and tools are inserted through the mouth, down the esophagus, and into the stomach pouch during an outpatient procedure.

The tools, developed by USGI Medical Inc., are used to grasp, fold and stitch tissue to reduce both the diameter of the stomach opening and the volume of the stomach pouch. No cuts are made into the patient’s skin.

Santiago Horgan, MD, professor of surgery and director of the Center for the Treatment of Obesity at UC San Diego, looked at the six-month outcomes from a national registry of 116 patients who underwent the procedure.

The data showed that 88 percent of the patients stopped regaining weight after ROSE.

Overall, these 96 patients lost an average 18 percent of their excess weight six months after the procedure. For the purposes of the registry, excess body weight is defined as anything over a body mass index rating of 55.

One patient in the study lost 66 pounds or 84 percent of her excess weight during that six-month time period. Patients who were most successful losing weight after their original gastric bypass had the best results following the ROSE procedure.

This subset of patients dropped 29 percent of their excess weight during the six months after ROSE.

“We believe this registry represents the largest collection of data showing the effectiveness, safety and durability of the ROSE procedure,” said Horgan.

“There are not many options to repair a failing gastric bypass. Invasive procedures to restore the anatomy are complicated and risky for most patients. In comparison, there were no significant complications associated with ROSE and most of the patients lost clinically relevant amounts of weight,” Horgan added.

The data was presented at the annual meeting of the American Society of Metabolic and Bariatric Surgeons. (ANI)

Mars was windy, wet and wild in ancient times

Washington, May 22 (ANI): The instruments aboard the Rover Opportunity, which are studying the Victoria Crater on Mars, has revealed more evidence of the red planet’s windy, wet and wild past.

According to Steve Squyres, Cornell professor of astronomy and the principal investigator for NASA’s Mars Exploration Rover mission, Opportunity’s two-year exploration of Victoria Crater – a half-mile wide and 250 feet deep – yielded a treasury of information about the planet’s geologic history and supported previous findings indicating that water once flowed on the planet’s surface.

The data shows that water repeatedly came and left billions of years ago.

Wind persisted much longer, heaping sand into dunes between ancient water episodes. These activities still shape the landscape today.

At Victoria, steep cliffs and gentler alcoves alternate around the edge of a bowl about 0.8 kilometers in diameter.

The scalloped edge and other features indicate the crater once was smaller than it is today, but wind erosion has widened it gradually.

“The impact that excavated the crater millions of years ago provided a golden opportunity, and the durability of the rover enabled us to take advantage of it,” said Squyres.

Imaging the crater’s rim and interior, Opportunity inspected layers in the cliffs around the crater, including layered stacks more than 10 meters (30 feet) thick.

Distinctive patterns indicate the rocks formed from shifting dunes that later hardened into sandstone, according to Squyres and 33 co-authors of the findings.

Instruments on the rover’s arm studied the composition and detailed texture of rocks just outside the crater and exposed layers in one alcove called “Duck Bay.”

Rocks found beside the crater include pieces of a meteorite, which may have been part of the impacting space rock that made the crater.

Other rocks on the rim of the crater apparently were excavated from deep within it when the object hit.

These rocks bear a type of iron-rich small spheres, or spherules, that the rover team nicknamed “blueberries” when Opportunity first saw them in 2004.

The spherules formed from interaction with water penetrating the rocks.

The spherules in rocks deeper in the crater are larger than those in overlying layers, suggesting the action of groundwater was more intense at greater depth.

Opportunity’s first observations showed interaction of volcanic rock with acidic water to produce sulfate salts.

Dry sand rich in these salts blew into dunes. Under the influence of water, the dunes hardened to sandstone.

Further alteration by water produced the iron-rich spherules, mineral changes and angular pores left when crystals dissolved away. (ANI)

Safer metal alloys may replace chrome coatings on bathroom fixtures, car bumpers

Washington, May 21 (ANI): Scientists have now found safer metal alloys to replace chrome coatings, which provides that shiny lustre to metal products like bathroom fixtures and car bumpers.

Researchers at the Massachusetts Institute of Technology (MIT) say that chrome not only adds beauty and durability, but could also be dangerous for workers during manufacturing and also pollutes the environment.

“People have been trying to replace it for a very long time. The problem is that it’s the only plated metal coating that has all of these properties – hardness, long-lasting shine and corrosion protection,” said Christopher Schuh, MIT associate professor of materials science and engineering.

But the researchers have now developed a new nickel-tungsten alloy that is not only safer than chrome but also more durable.

The new coating, which is now being tested on the bumpers of a truck fleet, could also replace chrome in faucet fixtures and engine parts, among other applications.

The technique used to coat metal objects with chrome-electroplating-involves running a current through a liquid bath of chromium ions, which deposits a thin layer of chrome on the surface of an object placed in the bath.

The ions, known as hexavalent chromium, are carcinogenic if inhaled, and contact with the liquid can be fatal.

Hexavalent chromium can pollute groundwater, and some of the original Superfund cleanup sites involved hexavalent chromium pollution.

“It’s an environmental nightmare,” said Schuh.

Chrome owes its hardness to its nanocrystalline structure, and thus the researchers decided to duplicate that structure with a material that could be easily and safely electroplated.

They used computer models to predict material properties, and settled on a nickel-tungsten alloy that is environmentally friendly and more durable than chrome.

The researchers have shown that nickel-tungsten alloys remain stable indefinitely at room temperature, and are highly resistant to decomposition when heated.

They can also be made harder and longer lasting than chrome and also the electroplating process is more efficient than that for chrome, because multiple layers can be applied in one step, which could save money for manufacturers.

“Not only do you get rid of the environmental baggage but you make a better product as well,” said Schuh.

The technology could be used to coat products like shock absorbers, print rolls and even electronics. (ANI)

Obama’s popularity rising, says NYT-CBS poll

New York, Apr.7 (ANI): President Barack Obama’s popularity with the American masses continues to be in ascendant mode, with the latest New York Times/CBS Poll pegging ratings at 66 percent.

Most Americans are confident that he is the right man for the job of rebuilding the nation’s confidence.

Fully two-thirds said they approved of his overall job performance, especially with regard to his handling of the economy, foreign policy, Iraq and Afghanistan.
By contrast, just 31 percent of respondents said they had a favorable view of the Republican Party, the lowest in the 25 years the question has been asked in New York Times/CBS News polls.

It is not unusual for new presidents to enjoy a period of public support. Still, the durability of Obama’s support contrasts with that of some of his predecessors at the same point in their terms.

The poll found that 70 percent of respondents were very or somewhat concerned that someone in their household would be out of work and looking for a job in the next 12 months.

Forty percent said they had cut spending on luxuries, and 10 percent said they had cut back on necessities; 31 percent said they had cut both.

By more than three to one, voters said they trusted Obama more than they trusted Congressional Republicans to make the right decisions about the economy.

More than two to one said they trusted Obama to keep the nation safe. Nearly one-quarter of Republicans said they trusted Obama more than Congressional Republicans to make the right decisions about the economy.

The survey was conducted Wednesday through Sunday, while Mr. Obama was in Europe for the Group of 20 summit of the world’s largest economies.

The national telephone poll was conducted with 998 adults. It has a margin of sampling error of plus or minus three percentage points. (ANI)

Gambhir, Dravid, Tendulkar lead India’s fight back in Napier Test

Napier, Mar.29 (ANI): India’s much vaunted batting machinery came to its rescue on Sunday, putting up 252 for the loss of two wickets in the second innings after being asked to follow on by New Zealand on Saturday.

India is now just 62 runs away from overtaking the Kiwi first innings total of 619 for nine declared, and have batters Gautam Gambhir (102 not out), Rahul Dravid (62) and Sachin Tendulkar (58 not out) to thank. The match, which concludes tomorrow, appears to be headed for a draw. India will, in all probability, set New Zealand a stiff target to chase after lunch or tea on the fifth day.

Led by Gautam Gambhir, India put up a dogged battle. Gambhir’s contribution to his team’s cause was invaluable, as he thwarted everything New Zealand threw at him while on his way to his fifth Test hundred.

Rahul Dravid and Sachin Tendulkar both weighed in with crucial innings, and the fact that New Zealand’s only wicket today was because of an umpiring error was indicative of India’s control.

It was a tough, combative performance from India’s batsmen while New Zealand were disciplined, rather than dangerous, and gave away only 205 runs in the day. But they lacked the edge to roll India over a second time on a track that is getting easier to bat on.

Tendulkar, on the other hand, reached his half century off 89 balls.

Gambhir’s effort surpassed his previous centuries for durability and given the immense pressure India were under. Ball by ball, minute by minute, over by over, Gambhir gnawed at a controlling New Zealand attack. Unlike Dravid, who has a reservoir of patience, Gambhir had to restrain himself and he did so admirably.

He crossed 2000 Test runs today, the third fastest Indian to do so after Virender Sehwag.
Dravid was the other man to thank. Before this tour his critics were questioning his form and two crucial half-centuries should silence everyone. Dravid carried heavy responsibility on his shoulders – not least because of his dismissal yesterday, which was the start of a collapse – but went about his business with great skill and efficiency. With stubborn support from Gambhir, he added 72 in the first session.

New Zealand appeared to employ the come-and-get-me strategy, using spin primarily and not placing much faith in pace. There was no swing for the fast bowlers, so the approach from Vettori and Patel was to keep it tight just outside off stump.

New Zealand will need to regroup and focus on playing intense cricket, much as India did on Sunday. (ANI)

IDF used 007 gadgetry during Gaza offensive

Jerusalem, Feb.18 (ANI): Israel’s Defence Forces (IDF) reportedly used gadgets seen quite often in James Bond movies during the recent offensive against the Hamas in the Gaza Strip.

For instance, there is a softball-sized camera that was thrown into a suspect house to transmit images to soldiers outside. Another item used was a special door-buster that is connected to an M-16 and can blow open booby-trapped portals.

The IDF Ground Forces Command put these weapon systems and others – most of them used during last month’s Operation Cast Lead in the Gaza Strip – on display in a military base in the South on Tuesday, the Jerusalem Post reported.

Called the Eyeball, the spherical camera was developed by the Tel Aviv-based company ODF Optronics.

An advanced, audio-visual surveillance sensor, the Eyeball was used by IDF troops during the Gaza offensive to survey homes and suspicious areas before entering them.

Each unit is only slightly larger than a baseball and can be simply thrown into the area that needs to be checked out. It can also be mounted on a pole or lowered on a cable into a tunnel.

Another product from the same company is the Eyedrive, a lightweight, four-wheel, remote-controlled, observation and surveillance mini-robot that provides continuous, real-time 360 degrees audio and video surveillance.

Due to its durability, the robot can be thrown on the ground, go down stairs, flip over and keep on going.

The IDF also tested the HTR 2000, a new sniper rifle that will be distributed to all infantry battalions. It has a range of more than 1,000 meters and can be used with a special night-vision add-on scope.

The adjustable heavy tactical rifle is made by H-S Precision INC in the United States.

Also used for the first time during the offensive was the Matador shoulder-launched anti-structure munition.

Used by infantry to destroy Hamas positions inside homes and other structures, the Matador incorporates an advanced tandem warhead concept that can be operated in two modes: against fortified positions and other structures, and to create a hole in a wall without destroying the inside of a home.

The system was acquired by the IDF in light of the Second Lebanon War, when infantry forces had problems hitting Hizbullah positions inside homes in the absence of a tank or attack helicopter.

The Ground Forces Command also put the IDF’s new armored personnel carrier on display. The Namer (Tiger) is based on the same platform as the Merkava MK4 Battle Tank and has the same high-level of reinforced steel protection. (ANI)

Step wall from Mughal period still exists in Pakistan

Islamabad, Feb 9 (ANI): One of the Mughal era’s architectural constructions, a step wall from that period, still exists in a well preserved condition, in Pakistan.

According to a report in The News International, the step wall, called as the ‘Losar Baoli’, is located among the Margalla Hills at Shah Allah Ditta, in the Potohar plateau.

Potohar plateau is the area which was the home of the Soan Civilization, which is evidenced by the discovery of fossils, tools, coins, and remains of ancient archaeological sites ranging from Stone Age to the Mughal architectural remains.

Being situated in the rich Potohar plateau, Margalla hills also preserves various remains of history which though lost their original shape, yet maintain the glory of the past kings and emperors.

The ‘Losar Baoli’, situated right upward the caves at Shah Allah Ditta, is thought to be constructed by Sher Shah Suri in order to facilitate the caravans moving towards Kabul via Taxila.

The traces of an old passage (darrah) are still found in its dilapidated condition, starting almost 100 feet upward from Shah Allah Ditta caves towards Girri (Taxila).

According to archeologists, this passage was regularly used by the Mughals and before that for the purpose of trade and other purposes.

Along with this old passage, a step well (Losar Baoli) constructed in grey limestone still exists.

The blocks, known as dressed blocks, are used in the construction of the step well in order to ensure its durability.

The width of the well is about six to eight feet while the steps of the well are still in their original shape.

Quoting famous archeologist Dr Dani, archeologist Ansar Ahmed said that the step wells were usually constructed during the regime of Sher Shah Suri, who in order to facilitate the caravans, used to construct these wells at the distance of almost 10 kilometers in a passage.

“He not only used to construct wells but also a mosque and an inn (Saraai) for the passengers so that they could continue their journey with comfort,” said Ahmed.

Ahmed pointed out that there were traces of step wells, mosques and inn in the way of Peshawar and Lahore and they are situated almost at the distance of 10 kilometers.

“There were several step wells either in their good or bad shape along with the trunk road,” he said.

According to Ahmed, although there were no traces found of any mosque or inn near the ‘Losar Baoli’ of Shah Allah Ditta, yet its relevance to Sher Shah Suri could not be denied. (ANI)

New NASA balloon successfully flight-tested over Antarctica

Washington, Jan 9 (ANI): NASA and the National Science Foundation have successfully launched and demonstrated a newly designed super pressure balloon prototype over Antarctica that may enable a new era of high-altitude scientific research.

The super-pressure balloon ultimately will carry large scientific experiments to the brink of space for 100 days or more.

This seven-million-cubic-foot super-pressure balloon is the largest single-cell, super-pressure, fully-sealed balloon ever flown.

When development ends, NASA will have a 22 million-cubic-foot balloon that can carry a one-ton instrument to an altitude of more than 110,000 feet, which is three to four times higher than passenger planes fly.

“This flight test is a very important step forward in building a new capability for scientific ballooning based on sound engineering and operational development,” said W. Vernon Jones, senior scientist for suborbital research at NASA Headquarters in Washington.

The test flight was launched December 28, 2008, from McMurdo Station, which is the National Science Foundation’s logistics hub in Antarctica.

The balloon reached a float altitude of more than 111,000 feet and continues to maintain it in its 11th day of flight.

The flight tested the durability and functionality of the scientific balloon’s unique pumpkin-shaped design and novel material.

The material is a special lightweight polyethylene film, about the thickness of ordinary plastic food wrap.

“Our balloon development team is very proud of the tremendous success of the test flight and is focused on continued development of this new capability to fly balloons for months at a time in support of scientific investigations,” said David Pierce, chief of the Balloon Program Office at NASA’s Wallops Flight Facility at Wallops Island, Virginia.

“The test flight has demonstrated that 100 day flights of large, heavy payloads is a realistic goal,” he added.

“The team has further work to do to enable the super pressure balloon to lift a one-ton instrument to a float altitude of 110,000 feet, but the team has demonstrated they are on the right path,” said Jones.

In addition to the super pressure test flight, two additional long-duration balloons have been launched from McMurdo during the 2008-2009 campaign.

Ultra-long duration missions using the super pressure balloon cost considerably less than a satellite and the scientific instruments flown can be retrieved and launched again, making them ideal very-high altitude research platforms. (ANI)
