The 1984 Windscale study raised concern about a possible association between living in the vicinity of nuclear power plants and childhood cancer. No such effect for all cancers was seen in ecological studies in Germany (1980-1995). Results from exploratory analyses led to a new study. Pre-selected areas around all 16 major nuclear power plants in Germany formed the study area. The design is a m...

This chapter presents several design examples of high-density, high-efficiency (HDHE), low-voltage power supply using the proposed IM circuits. The theoretical results derived from the previous chapters are applied. The following examples will be used to demonstrate the design of high density modules using the proposed IM technique. • For 70V input and 2.5V/140A output, at the switching frequen...

The objectives of this paper are to investigate and develop a device that will produce high voltage low power supply. Generation of high voltage low power supply can be determined by using Flyback converter as an optimum method which can improve the design of the device to make it smaller in size, simpler and cost effective. In this paper, the device circuits are simulated using PSPICE software...

Currently, there is a trend in nuclear power plants (NPPs) toward introducing digital and computer technologies into main control rooms (MCRs). Safe generation of electric power in NPPs requires reliable performance of cognitive tasks such as fault detection, diagnosis, and response planning. The digitalization of MCRs has dramatically changed the whole operating environment, and the ways opera...

System designers are being asked to reduce overall power in order to lessen the impact on our environment, while reducing both capital and operating costs. They are also being asked to increase circuit density so that electronic systems can be pushed into smaller form factors and operate in harsher environments. Unfortunately, incorporating high power solutions into these systems causes signifi...

Background: Myofacialpain syndrome and fibromyalgia are two painful  clinical disorders of soft tissues that encountered to pain specialists. Low level laser therapy is  one of the non-pharmacological treatment modalityseems controversial.  Aim of this review articles is to investigate of  the efficacy of low level laser therapy (LLLT) in fibromyalgia  and myofacial  pain patients in the litera...
