this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
Insulin is an important biotherapeutic protein, and it is also a model protein used to study amyloid diseases, such as Alzheimer's and Parkinson's. The preparation of the protein can lead to small amounts of aggregate in the solution, which in turn may lead to irreproducible in vitro results. Using several pre-treatment methods, we have determined that pH cycling and diafiltration of the insuli...
Lignocellulosic biomass is a valuable renewable resource that has the potential to be refined into multiple fractions of biomaterials. Extracting and purifying lignin without compromising cellulose quality challenging goal. Deep Eutectic Solvents (DESs) have been reported as suitable delignification solvents, for process development extraction, removal essential. This work describes an investig...
abstract this study attempted to investigate the strategies used to translate clichés of emotions in dubbed movies in iranian dubbing context for home video companies. the corpus of the current study was parallel and comparable in nature, consisting of five original american movies and their dubbed versions in persian, and five original persian movies which served as a touchstone for judging n...
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
The current state of the art on studying whey is considered. processes and methods processing (thermal, chemical, physicochemical, biotechnological, electrophysical) are presented. Thermal isoelectric precipitation proteins, using reagents coagulants, as well main membrane (reverse osmosis, diafiltration, microfiltration, ultrafiltration, nanofiltration) described. Possibi-lities effective sepa...
Zirconia ultrafiltration membranes are widely developed and used for past several years. But the conventional sol-gel methods of zirconia membrane preparation involve many steps. In the present study an attempt was made to develop defect free zirconia ultrafiltration (UF) membrane in single step coating of zirconia nanopowder suspension by slip casting method over multichannel ceramic support. ...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
