Highly ordered gallium indium phosphide layers with the low bandgap have been successfully grown on the (100) GaAs substrates, the misorientation toward [01-1] direction, using the low-pressure metal organic chemical vapor deposition method. It is found that the optical properties of the layers are same as those of the disordered ones, essentially different from the ordered ones having two orie...

Efficacy and safety are primary considerations in registration and use of toxicants for vertebrate pest controlo Strychnine (0,5$) and zinc phosphide (2$) are currently registered by EPA for prairie dog control, but continued registration is uncertain. Two percent zinc phosphide bait has been suspected of producing lower and more erratic results than strychnine baito In our study in western Neb...

The influence of InGaAlAs waveguide layer composition on the photoluminescence and electroluminescence in 1550-nm spectral range heterostructures based thin strained In0.74Ga0.26As quantum wells has been studied. An approach is proposed that allows analysis electroluminescence.to carry out a comparative deferential gain fabricated laser diodes. It shown decrease molar fraction aluminum layers m...

In this article, the anti-poison performance of novel Al-6Y-2P master alloy for impurity Ca in hypereutectic Al-Si alloys was investigated in detail. According to the microstructural analysis, it can be found that the primary Si and eutectic Si particles could be relatively modified and refined. In order to investigate the influence mechanism of Ca on the limited refinement performance of Al-6Y...

Procedures for the analysis of phosphorus in geological material normally aims for the determination of the total amount of P expressed as orthophosphate [Formula: see text] or the differentiation between inorganic and organic P. This is probably due to analytical difficulties but also to the prevalent opinion that the chemistry of phosphorus in geological environments is almost entirely restri...

Aluminium Phosphide poisoning and glucose-6-phosphate dehydrogenase deficiency are two commonly seen clinical presentations in Iran. However, hemolysis associated with Aluminium Phosphide poisoning is very rare. We report a case of concurrent Aluminium Phosphide poisoning and glucose-6-phosphate dehydrogenase deficiency in a 24 year old man presenting with intravascular hemolysis.
