The reliable production of large amounts of stable, high-quality proteins is a major challenge facing pharmaceutical protein biochemists, necessary for fulfilling demands from structural biology, for high-throughput screening, and for assay purposes throughout early discovery. One strategy for bypassing purification challenges in problematic systems is to engineer multiple forms of a particular...
the abrasion is a significant issue, especially in machining of rigid steels. a functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. the objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...

Microbial populations often rely on the cooperative production of extracellular " public goods " molecules. The cooperative nature of public good production may lead to minimum viable population sizes, below which populations collapse. In addition, " cooperator " public goods producing cells face evolutionary competition from non-producing mutants, or " freeloaders ". Thus, public goods coopera...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
