CASE (Computer Aided Software Engineering) tools are believed to have played a critical role in improving software productivity and quality by assisting tasks in software development processes since 1970s. Several parametric software cost models adopt “use of software tools” as one of the environmental factors that affects software development productivity. Several software cost models assess t...

this research, in addition to survey the existing data on the quality of sahebgharanieh wastewater treatment plant's effluent in the previous years, by runing a three months monitoring stage, studies the conditions of the final settling and aeration basin and the variations of the influent and effluent quantity and quality in removing of major pollutants (bod, cod, tss), while scrutinizing the ...

background escherichia coli (e. coli) species are able to produce extended-spectrum β-lactamases (esbls) that cause high resistance to the beta-lactam antibiotics. therefore, determining the antibiotic susceptibility patterns in resistant organisms is necessary for suitable therapeutic approaches. patients and methods totally, 260 clinical isolates of e. coli were collected from hospitals in te...

background & objectives:extended-spectrum-b-lactamase (esbl)-producing strains of klebsiella pneumoniaare an important cause of many serious infections in hospitalized and nonhospitalized patients and delayed treatment of these infections in crease chance of death in patients. this study was performed to determine the prevalence of esbl-producing k. pneumonia and to evaluate the frequency o...

nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...

Abstract—As the higher security per bit compared with traditional symmetric-key cryptography, public-key cryptography has always been attractive in security system. But usually the cost is high and efficiency is low because of complex algorithm. Unlike common hardware solution based on FPGA or system on chip (SOC), an instruction set architecture (ISA) extension of embedded processor has been p...
