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.sunsprostore.com/Cheap-Eric- ... ns-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, 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.sunsprostore.com/Cheap-Draga ... ns-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, 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.sunsprostore.com/Cheap-Devin ... ns-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.
Granny flats are probably the best thing to happen for baby boomers nearing retirement age and those elderly relatives who want to stay as close to their families as possible and can’t really afford the high costs of living in aged-care facilities and nursing homes. While the latter may ensure that they get round-the-clock care and attention, nothing beats being taken care of by your own flesh and blood.

Also, the economic crunch that has resulted into lack of affordable housing also contributes greatly to the rise of granny flats. It would’ve risen sooner except that there were laws in place that didn’t allow all states to build granny flats because they didn’t meet zoning requirements for the local districts. Other problems that were also encountered were the lack of proper permits and that most granny flats didn’t adhere to the local building codes. You can find out about what requirements you’ll need to start building your granny flats on sites like www.valleykithomes.au if you want to do research on them.

However, in recent times, there has been a resurgence of granny flats that is primarily contributed to the 2009 NSW government policy of enabling 10-day approvals for secondary dwellings on a property but this doesn’t mean though that you can just go ahead and build one in your backyard. First off there are still regulations that you need to adhere to and they are as follows:

• Your granny flat must be constructed within a residential zone, with your block measuring a minimum of 450 square meters. Each residential unit as well is limited to one granny flat only.

• The owner of the granny flat must also be the owner of the main residence.

• While a granny flat can also have carports http://www.sunsprostore.com/Cheap-Dan-M ... ns-Jersey/ , patios and verandahs, it must have no more than 60 square meters of living space.

• They can either be attached to the main residence or constructed as a separate unit.

• They cannot be built on unoccupied land or those that are being used for commercial purposes.

• They must also have unobstructed pedestrian access if you are planning to convert part of your house as a granny flat, they must have a separate entrance from that of the main house.

• Granny flats also cannot exist on strata, subdivided or community title property.

More and more people as well, find it financially rewarding to build their granny flats on the same block as their main residence because not only does this add resale value to your property, it also gives you a substantial rental yield depen.
