The profile of light emission from aluminum gallium indium phosphide AlGaInP light emitting diodes has been studied and compared with the theoretical modeling of current spreading using a lossy transmission line model of current injected into the active region. Discrepancies between the experimentally determined emission profile and the theoretically predicted current injected into the active r...

  Purpose: to investigate the effects of phosphide on some human biological systems in order to find a way to control it and facilitate the prevention and treatment of its poisoning.   Materials and Methods: In this study, 67 files of autopsy description, forensic pathology results and forensic toxicology were studied as nominal qualitative variables in terms of each type of histological change...

In many parts of the developed world, the sale and use of phosphide is under strict regulations with adequate training of workers being a major perquisite before its use. In Nigeria this chemical is commonly available and in most cases users are largely untrained, therefore contamination of cowpea with residual phosphide post-fumigation does occur. The aim of this study is to determine the impa...
