Lightweight composite metal foams could prove to make all the difference when it comes to x-ray and gamma ray shieldingand neutron radiation protectionas they can absorb the energy created during high-impact collisions Wholesale Oakland Athletics Jerseys , says study. This study was published in the Radiation Physics and Chemistry Journal and was authored by researchers from NC State. The work was also supported by the Nuclear Energy University Program grant offered by DOE’s Office of Nuclear Energy. “There’s an opportunity to use composite metal foam to develop safer systems for transporting nuclear waste, more efficient designs for spacecraft and nuclear structures, and new shielding for use in CT scanners,” says AfsanehRabiei Wholesale New York Yankees Jerseys , one of the authors of this study, professor of aerospace engineering at NC State. This means that metal foams could be extremely useful for space exploration applications, medical technology and nuclear safety. This lightweight metal foam was first built to be used in military and transportation applications, but the authors also wanted to determine whether it could be helpful in space exploration applications and nuclear radiationprotection Wholesale New York Mets Jerseys , and to examine whether this metal foam could protect against high impact, offer structural support and provide radiation shielding against different types of radiation. To examine its use, the study conducted several tests to examine the foam’s effectiveness at gamma ray shielding, x-ray shielding and radiation protection. This was then compared to the performance of materials that are currently being used in all kinds of shielding applications. The comparison proved that while each sample had the same weight Wholesale Minnesota Twins Jerseys , it varied in terms of volume. A composite material known as high-Z steel-steel was found to be the most effective in offering protection against all three forms of radiation. This metal is mostly comprises of stainless steel, but it also contains small quantities of tungsten. The major difference is that its structure was modified so that the composite foam which included tungsten wasn’t denser than metal foams made using stainless steel only. The shielding performance of this new material was then tested against different types of gamma rays as gamma rays can have different energies depending on the source material. For example, barium emits low energy gamma rays while cobalt or cesium emits higher-energy rays. The study went on to show that high-Z steel-steelfoam was on par with most bulk materials at blocking high-energy gamma rays, but it was far better than most Wholesale Milwaukee Brewers Jerseys , including bulk steel, in blocking out low-energy gamma rays. The material also outshone others when it came to neutron radiation protection and x-ray shielding. This foam is non-toxic which makes it easy to recycle and manufacture. It can also act as a viable candidate for nuclear structural applications because of its thermal and mechanical properties, and its capability to absorb energy. Researchers are now working on modifying the composition of this metal foam to make it a more effective shield against x-rays. Rabiei says that early results are extremely promising. Donald Trump is expected to remain physically fit for the duration of his presidency and has "no cognitive issues whatsoever," according to full results from his first medical examination released Tuesday. Trump's critics have openly questioned his mental health Wholesale Miami Marlins Jerseys , and an explosive book on his presidency published earlier this month described aides as having doubts about his fitness for office. "All data indicates the president is healthy and will remain so for the duration of his presidency," doctor Ronny Jackson told a White House briefing following last week's physical, which determined the 71-year-old to be in "excellent" health. "He has incredible genes and that's the way God made him." Jackson said Trump, who has recently faced a swirl of speculation about his mental fitness Wholesale Los Angeles Dodgers Jerseys , had himself requested a cognitive test in which he performed "exceedingly well." "I think he saw doing the physical as an opportunity to put some of that to rest," Jackson said. "And I think he wasn't the least bit concerned that he had anything to hide." The screening was carried out using a test called the Montreal Cognitive Assessment, on which Trump scored 3030, Jackson said. Jackson gave the president's vital statistics as follows: height six feet three inches (1.90 meters) Wholesale Los Angeles Angels of Anaheim Jerseys , weight 239 pounds (108 kilograms), resting heart rate 68, blood pressure 12274. Trump will be making some changes to his diet and exercise in an effort to lose weight. "I think a reasonable goal over the next year or so is to lose 10 to 15 pounds. We talked about diet and exercise a lot. He's more enthusiastic about the diet part than the exercise part, but we're gonna do both Wholesale Kansas City Royals Jerseys ," said Jackson. "There's a gym upstairs and we'll get that set up to his specifications and we'll see how that goes." Heart rate, blood pressure and cardiac output were all normal in response to exercise, while motor function and sensory system were also normal, Jackson said of Friday's exam at the Walter Reed National Military Medical Center. Long-running questions about Trump's fitness for office were given new fuel by Michael Wolff's White House expose in which staff expressed concern about Trump repeating himself. Wolff expounded further in an interview with NBC's "Today" show Wholesale Houston Astros Jerseys , saying: "One hundred percent of the people around him" question Trump's fitness for office. "They all say he is like a child. And what they mean by that is he has a need for immediate gratification. It's all about him," said Wolff. Trump described the book as "full of lies," and described himself as "a very stable genius." (Agencies) .

The binary addition algorithm is a bit-pattern manipulation procedure that is built into the hardware of (nearly) all computers. ... The left bit of the result is called the "carry out of the column". To add two 1-bit (representations of) integers: Count the number of ones in a column and write the result in binary. |
