Pragmatic aspect of second language (L2) as a component of communicative competence has recently received more attention. Many research studies have investigated the gap between native and nonnative speakers’ command of L2 pragmatics. However, development of L2 pragmatics has been the focus of few studies. In this study, how coursebooks can help both nonnative teachers and learners develop L2 p...
We have studied the adsorption processes of H2 on the V (100) surface of Vanadium using self consistent field theory.Dissociative adsorptions of H2 are significantly favored compared to molecular adsorptions. There is a significant charge transfer from the first layer of the vanadium surface to the Hydrogen atoms. Three possible adsorption sites, top, bridge and center site, were considered in ...
Background and Aim: Managers today work in a dynamic environment. Their role in creating quality is essential. Today paying attention to the quality of goods and services is the first Paiority in heath care organizations which is in with contact peoples lives. Total Quality Management has undergone vast changes in health care management. The aim of this study is to determine the top (chief) ...
This study was carried out to investigate different data transformation methods on homogeneity and heterogeneity of variance components. Data included 305-day lactation records for protein yield from the first three lactations of Iranian Holstein cows collected from 1983 to 2014 by the Animal Breeding Center and Promotion of Animal Products of Iran. Data included 141670 records for 1st lactatio...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
adsorption of anilofos was studied in four soils (topsoil from alfisol, inceptisol, oxisol and vertisol). the order of adsorption of anilofos was vertisol > oxisol > alfisol > inceptisol. the soil sorption coefficient k and the soil organic carbon sorption coefficient koc are the basic parameters used for describing the environmental fate of the herbicides. in top soil the calculated k values w...
در پایان نامه ی پیش رو ضمن تعریف فضای جهت دار، چند مثال از آن را ذکر خواهیم کرد. هم چنین به معرفی کتگوری تولید شده توسط یک زیرکتگوری می پردازیم و دو مثال مهم یعنی کتگوری تولید شده توسط مکعب های جهت دار و کتگوری تولید شده توسط سادک ها را ارائه خواهیم کرد. علاوه بر این ضمن تعریف دو فانکتور جعبه ساز و سادک ساز، نشان خواهیم داد زیر کتگوری فضاهای جهت دار تولید شده توسط مکعب های جهت دار با زیرکتگوری ...
