abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...
Unsuitable planting and weed competition are the most important factors that greatly reduce the yield of bean. In order to study the effect of planting date on yield and yield components of three white bean cultivars in weed infest and weed free condition a factorial experiment with randomized complete block design and three replications was carried out at Semirom in 2009. The treatments were p...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Plant growth promoting rhizobacteria are known as an alternative to chemical fertilizers, which are able to reduce the harmful effects of non-biological stresses such as salinity and increase soil fertility and crop production. This study was conducted to investigate the effect of inoculation of Pseudomonas fluorescens strain FY32 on a number of morphological characters in canola cultivars unde...
in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...
Abstract: Salinity is one of the most important factors that limit plant growth and production in the whole word. Compounds, which are able to reduce the damaging effects of various stresses such as salinity, should be of great important. In this investigation, the effects of spermidine on salt tolerance of Matricaria recutitaa were investigated. The results showed that, salt stress in c...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
A breeding hexaploid salt tolerant wheat line (MS-81-14) was produced from crossing of an Iranian salt tolerant wheat line (1-66-22) with Inia cultivar (from CIMMYT) at Karaj Research Station in 1991-92 cropping season. The F1 plants were grown at Karaj in 1992-93 cropping season, furthermore F2-F6 populations were evaluated under salinity stress conditions (EcSoil&Water = 8-12 ds/m) in Isfah...
salinity of water and soil in arid and semi arid regions restricts the growth and yield of crops such as sesame. in order to evaluate yield and yield components of 43 lines and ecotypes of sesame (sesamum indicum l.) under saline condition (ec of irrigation water, 5.2 ds m-1) an experiment was carried out in randomize complete block design with three replications at salinity research station of...
