Dampening is a process whereby mechanical energy is converted to thermal energy. Materials or systems under cyclic stress have a damping ability which is an energy dissipation property. The energy that is dissipated is used to measure the material damping level.

Thermoplastic composite materials are praised as a new generation of composite materials which have many applications in a wide range of industries. Since they are manufactured by bonding two or more materials of different physical and chemical properties, the composite materials take the advantages of the best characteristics of their component materials. During the production process, they are heated and cooled repeatedly to enhance the materials’ strength and damage toler

The latest incident of a severe radioactive leak at Japan’s Fukushima Daichii nuclear plant three years ago following a disastrous earthquake and tsunami has brought the topic of radiation shielding and how to protect oneself from radiation to the forefront of the world’s attention. However, for policy makers and companies working in industries that frequently deal with radiation and radioactive materials these were not new concerns. In fact, they have long given special a

Anyone working in the field of radiation protection is well aware of neutrons, neutron radiation and the adverse effects it can have on living things. Neutrons form the basis of an atom, and together with protons, they make up more than 99 percent of the mass of an atom. The chance of neutron ejection is pretty slim and hard to detect, and usually occurs only as a result of nuclear fission and radioactive decay. Depending on the exposure dose, the effects of neutrons on living

Radiation is no stranger to the earth. There have always been a large amounts of radiation coming from various sources that the earth is exposed to constantly, but the earth’s atmosphere absorbs most of them. However, nowadays, the types of radiation that people have to be concerned with come mainly from man-made sources. Many companies working in such fields as the medical, nuclear, and aerospace industries utilize and depend upon equipment that emits radiation. It is widel
