|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 http://www.pittsburghpenguinsteamstore.com/adidas-tom-kuhnhackl-jersey , 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 http://www.pittsburghpenguinsteamstore.com/adidas-tom-barrasso-jersey , 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 http://www.pittsburghpenguinsteamstore.com/adidas-sidney-crosby-jersey , 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 http://www.pittsburghpenguinsteamstore.com/adidas-scott-wilson-jersey , 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 http://www.pittsburghpenguinsteamstore.com/adidas-ryan-reaves-jersey , 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.
Like any other game or sport, golf requires that you are geared up correctly to be able to properly take part fully in the game. This article will give you a basic conception of basic golf equipment a golfer requires to be proficient to understand and play golf.
To start with http://www.pittsburghpenguinsteamstore.com/adidas-ron-francis-jersey , the minimum piece of golf equipment is a golf ball. These balls are always dimpled, they are tiny , and vital to your game of golf. They are designed to fly much further distances when 'driven' hard during your game.
Another 'must-have' in golf equipment is a 'golf club' or 'driver'. The Golf 'drivers' are made in many differing varieties. This is because a golf course has different landscapes and various golf clubs are required to create the proper drive. It depends so much on the landscape, could be sand http://www.pittsburghpenguinsteamstore.com/adidas-riley-sheahan-jersey , maybe grass or, in some cases, even cement, a club is absolutely essential to make that perfect drive.
Pro golfers invariably have a couple of golf club bag trolleys to provision to their golf needs. Most golf stores and sports kit outlets sell golf clubs. Some golf clubs are sold in sets whilst other are sold individually.
To protect your golf equipment http://www.pittsburghpenguinsteamstore.com/adidas-phil-kessel-jersey , such as your golf club, a golf bag golf club cover is important. A golf bag will, of course, hold your golf club in one spot and will make it easier for your caddy to bring your many golf clubs. Golf baggage can also hold golf balls and other golf equipment like a drinks bottle to quench your thirst while under the sun or an additional shirt or your regular shoes.
On the other side of the coin http://www.pittsburghpenguinsteamstore.com/adidas-paul-martin-jersey , a golf club sleeve covers the edge of your golf club. This is necessary so to protect your golf club from those accidental scratches and dents. Dents can make your drive to go from ok to bad.
Dents in golf clubs can affect the drive of your golf ball. With these golf clubs, you can take very good care of the state of your golf club and your game.
One golf equipment we feel you need to lay out on is a good pair of golf shoes.
Golfing footwear is different from every-day rubber shoes or the average walking shoes. Golf shoes are created to not make indents or other marks on greens - the species of grass where the sport is played. Golf shoes usually have spiked rubber under the soles to grip the earth and sand under your feet.
In this way, all unnecessary movement is avoided. This is a crucial point because any movement at all can inadvertantly cause you to incorrectly hit the golf ball or to hit the golf ball in the area of the course you do not want to be .
If you plan to play professional golf a decent pair of golf shoes .
