Glycosyltransferases are specific enzymes that catalyse the transfer of monosaccharide moieties to biological substrates, including proteins, lipids and carbohydrates. These enzymes are present from prokaryotes to humans, and their glycoconjugate products are often vital for survival of the organism. Many glycosyltransferases found in fungal pathogens such as Cryptococcus neoformans do not exis...

The emergence of third-generation photovoltaics based on Si relies on tunable bandgap materials with embedded nanocrystalline Si. One of the most promising approaches is based on the mixed-phase Si1 - xCx. We have investigated the light absorption controllability of nanocrystalline Si-embedded Si1 - xCx produced by thermal annealing of the Si-rich Si1 - xCx and composition-modulated superlattic...

the mikkes basin is located at the north center of morocco. it comprises three different zones which represent diversified geologies which shelter a phreatic and confined aquifer in the sais basin and a shallow aquifer in the tabular middle atlas. the springs in the sais phreatic aquifer have suffered a maximum depletion. the springs with a deep or mixed origin are known as low flow variation s...

background: the aim of this study was to identify the trichomonas vaginalis strains/haplotypes based on identifying their probable variations in asymptomatic patients referred to tabriz health centers, northwestern iran. methods: sampling was taken from 50-suspected women to t. vaginalis in northwestern iran. the obtained samples were smeared and cultured. fifty dna samples were extracted, ampl...

the study of teachers’ pedagogical knowledge base (pkb) to discover how teachers think and work is attracting increasing attention in elt. against this background, the present study aimed at probing the likely variations in efl teachers’ pedagogical knowledge base as a function of their teaching license status. to this aim, six teachers (two standard-licensed, two alternatively-licensed, and tw...

operational variables of a mineral processing circuit are subjected to different variations. steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. in thispaper, a dynamic simulator containing some of the major equipment of mineral processing...
