The recovery of selenium from Iranian sar-cheshmeh copper anode slime has been investigated. Copper anode slimes are containing varying precious metals, such as: gold, silver, selenium and tellurium. They are being extracted as a by-product in the production process. Arsenic and antimony that present in anode slimes dissolved in 0.4 M KOH. Then, the alkaline roasting of anode slimes in the pres...
Background: Meniere’s disease is a clinical disorder defined as the idiopathic syndrome of endolymphatic hydrops. has prevalence about 200 cases per 100,000 people in United States. Prevalence increases linearly with increasing age, especially over 60 years. Men and women are estimated to be proportional number cases. The etiology currently known caused by intrinsic factors extrinsic factors. S...
Uranium becomes soluble and mobile under oxidizing conditions in aqueous environment, and presence of complexing agents with uranium increase this mobility. Existence of such conditions in groundwaters of Ayrakan and Cheshmeh Shotori areas has led to oxidation, solubility and mobility of uranium minerals. Hydrogeochemical study of uranium in the study areas reveals the presence of bicarbonate i...
Generalized speedup is deened as parallel speed over sequential speed. In this paper the generalized speedup and its relation with other existing performance metrics, such as traditional speedup, eeciency, scalability, etc., are carefully studied. In terms of the introduced asymptotic speed, we show that the diierence between the generalized speedup and the traditional speedup lies in the deeni...
This paper presents a portable parallel programming environment for Modula-2* { an explicitly parallel machine-independent extension of Modula-2. Modula-2* ooers synchronous and asynchronous par-allelism, a global single address space, and automatic data and process distribution. The Modula-2* system consists of a compiler, a debugger, a cross-architecture make, a runtime systems for diierent m...
Kinases control virtually all aspects of biology. Forty-eight human proteins have a kinase-like domain that lacks at least one of the conserved catalytic residues; these proteins are therefore predicted to be inactive and have been termed pseudokinases. Here, we describe exciting work suggesting that pseudokinases, despite lacking the ability to phosphorylate substrates, are still pivotal in re...
