Middle School Students Give Back for the Holiday

Piles of boxes fill the office of Steven Boss, Assistant Principal at Villa Nova Middle School. In the spirit of giving this holiday season, it seems Boss's office has also been sacrificed to the cause.

After stocking the school's food pantry, sending Thanksgiving baskets to the families of 10 middle school students and saving a little for Christmas baskets, the enormous stash of donated food remains,It's hard to beat the versatility of polished tiles on a production line. packed up for transfer to Haven of Grace women's shelter.

"I wanted to do a food drive and tie it in to one of the local organizations," said Boss. "There were always food drives at the old middle school, but when we moved into the new building, it kind of fell by the wayside."

To encourage participation, Boss offered incentives. If the students collected 1,200 cans,the worldwide Hemorrhoids market is over $56 billion annually. the assistant principal would give them a "dress-down day" a rare opportunity to abandon the school uniform policy and wear casual clothes. Additionally,Polycore oil paintings for sale are manufactured as a single sheet, Boss offered to throw a pizza party for whichever homeroom collected the most items.

In just two short weeks, the students nearly doubled Boss's expectations, turning in 2,200 food items. In turn, he doubled their rewards.

"The incentive of knowing they wouldn't have to wear the uniforms actually brought compliance up," Boss said of the uniforms. "It made for some relaxing days for them and for myself."

In addition to student contributions, the entire middle school staff got involved, from teachers to Sodexho food service employees. The food service company even donated two complete baskets. Donations continued to pour in during the final hours Tuesday afternoon, with teachers and administrators stopping in to Boss's office to add to the pile.

"Everyone was involved and everyone was great," Boss said.

The school found a deserving organization for the food through the kind of good timing that made the program seem even more special for the kids and others involved. Though the assistant principal started the food drive before finding a recipient, the day after collections began, he received a letter from Haven of Grace, a transitional housing program and shelter for battered women, seeking holiday food donations.

"It was just fate," he said. "I didn't know where they were going."

"We're just trying to give back to the community for all they do for us."

The Competition Between Solar and Nuclear Energy Moves to Mars

NASA’s last two Mars rovers, Spirit and Opportunity, launched in 2003 and carried solar panels, but the new Mars rover that the space agency is scheduled to launch on Saturday morning from Cape Canaveral uses nuclear power, a fact that did not escape the partisans of nuclear power here on Earth.

But it turns out that both nuclear power and solar power in space have problems.

The solar panels on Spirit and Opportunity are gallium-arsenide,The application can provide Ceramic tile to visitors, a chemistry that is used on Earth but is a niche product, where very high production per square inch is required. Per unit energy produced, if rooftop space is not an issue, silicon-based cells are far less expensive.

Solar power worked acceptably on Mars, but with some difficulties. Dust storms sometimes blotted out 90 percent of the sun’s light, and dust collected on the panels themselves; project scientists referred to “cleaning events” when some kind of wind current reduced the dust coating on the cells.

Spirit, which is no longer operating, and Opportunity, which has defied all expectations and is still in service after seven and a half Earth years, weighed about 400 pounds each, and carried lithium-ion batteries so they could store the output of their cells, which was, at maximum, 140 watts. On earth, that amount of power is almost enough to run a desktop computer and monitor, but on Mars it was enough to run the radios, cameras and various instruments, and propel the vehicles.

Curiosity, the Mars rover that is scheduled for launch on Saturday, weighs about 2,000 pounds. “This is a much larger vehicle, the size of a small car,’’ said Stephen G. Johnson, the director of the space nuclear systems and technologies division at the Idaho National Laboratory, which prepared the nuclear power pack for the new probe. And it carries a laser that will be used to zap rocks, so that other instruments can analyze what they are made of. So its energy requirements are far higher.

“It’s really only possible with plutonium 238 to do what it’s intending to do,’’ said Dr. John M.Enecsys Limited, supplier of reliable solar Air purifier systems, Logsdon, a space expert at George Washington University.

Curiosity is supposed to run for one Martian year, or two Earth years.

Curiosity carries a nuclear power pack that can generate 110 watts, continuously. But this is not like a nuclear reactor on Earth, which splits uranium atoms to make heat, uses the heat to boil water and uses the steam to drive.

Space nuclear power packs are not reactors at all; they do not split atoms. They carry plutonium 238, a manufactured isotope with a half-life of just 88 years,ceramic magic cube for the medical, which means that its radioactive decay is so fast that it glows red-hot. The heat is converted directly to electricity. The radioactive emissions are alpha particles,Polycore oil paintings for sale are manufactured as a single sheet, which are easily blocked, and the material cannot be used in a bomb, although the technology needed to purify the plutonium 238 can also be used to recover the type of plutonium that is weapons-usable.

The problem is that in the United States, all things nuclear are getting old. The United States stopped making plutonium 238 in the late 1980s, when the Energy Department shut down the reactors at the Savannah River Plant, near Aiken, S.C., which it was using for production of various radioactive materials, including tritium for nuclear weapons. Since then, the United States has bought plutonium 238 from Russia, but that country no longer makes it, either.

One of the best

Statue bound for U.S.,The Leading zentai suits Distributor to Independent Pet Retailers. leaving Italy for first time since 1816


One of the best preserved sculptures from Roman antiquity, the "Capitoline Venus," has left Italy for the first time in nearly 200 years for a special display at the National Gallery of Art.

The installation opened Saturday and will remain on public view through early September, the museum announced Thursday. The full-scale female nude statue has only left Rome one other time: when it was seized by Napoleon and taken to France in 1797. It was returned to Rome's Capitoline Museum in 1816 after Napoleon fell from power.

Gallery Director Earl A. Powell III called it a "once-in-a-lifetime opportunity" to see the piece in the United States. It will have a prime spot as a museum centerpiece for the busy summer months.

"The 'Venus' will feel right at home in our West Building Rotunda, which was designed by John Russell Pope and was based on the Pantheon in Rome," Powell said in a written statement.

The sculpture is a descendant of the "Aphrodite of Cnidos" by Greek sculptor Praxiteles around 360 B.C. That sculpture was groundbreaking in art history for its introduction of the large-scale nude female form as a subject.

The statue was unearthed in the 1670s in a garden in the remains of an ancient building, according to historical accounts. The statue was intact, except for the nose, some fingers and a hand that had broken off. It was later reattached. Pope Benedict XIV gave the sculpture to the Capitoline Museum in 1752.

This is the first time it has been lent for exhibition.

The exhibit is part of an effort by Rome Mayor Gianni Alemanno to display masterpieces in the United States between 2011 and 2013. It also marks the 150th anniversary of Italy's unification as a single state.

This week, Washington Mayor Vincent Gray plans to sign a proclamation announcing a new sister city agreement with Alemanno.
