abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...

Subcooled flow boiling in multi-microchannels can be used as an efficient thermal management approach in compact electrical devices. Highly subcooled flow boiling of HFE 7100 is studied in two microchannel heat sinks to choose a proper numerical model for simulating boiling flows in microchannels. Results of five different numerical models, including Volume of Fluid (VOF), Eulerian boiling, Eul...

cohesion is an indispensable linguistic feature in discourse analysis. lexicald such a differe cohesion and conjunction in particular as two crucial elements to textual cohesion and comprehension has been the focus of a wide range of studies up to now. yet the relationship between the open register and cohesive devices has not been thoroughly investigated in discourse studies. this study concen...

In stark contrast to other agency-based consumer service industries, real estate agents have been remarkably effective at maintaining margins and market share. One possible explanation for the success of real estate agents is collusion, and consequently the industry is facing regulator scrutiny. In this paper we first consider the mechanisms through which collusion might be sustained. Although ...

We discuss how laboratory experiments can be used to place constraints on possible variations of the fine structure constant α in the observationally relevant redshift interval z ≃ 0 − 5, within a rather general theoretical framework. We find a worst case upper limit for ∆α/α of 8 × 10 −6 for z ≤ 5 and ∆α/α of 0.9 × 10 −6 for z ≤ 1.6. The derived limits are at variance with the recent findings ...

background: the aim of this study was to propose a new stochastic model to study the time course of ethanol elimination in human bodies. methods: the times and amount of alcohol ingested are assumed to be random in controllable intervals. constant elimination rate follows zero order kinetics and is replaced by first order kinetics when the effects of alcohol increase due to alcohol ingestion. s...

به طور کلی در فرآیندهای مارکوف ارگودیک دو بعدی یافتن فرم بسته توزیع ایستا، تنها برای حالات خیلی خاص امکان پذیر است. با توجه به این مشکل و نیز با توجه به اهمیت توزیع ایستا، بررسی و مطالعه رفتار مجانبی توزیع ایستای این فرآیندها مورد توجه قرار گرفته است. زنجیر قدم زدن تصادفی دو بعدی که در برخی متون به آن، فرآیند qbd دو طرفه نیز می گویند، یکی از این فرآیندها است. یک فرآیند qbd زمان گسسته یک زنجیر م...
