toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
Abstract—Nitrogen fertilizer is the most used and often the most mismanaged nutrient input. Nitrogen management has tremendous implications on crop productivity, quality and environmental stewardship. Sufficient nitrogen is needed to optimum yield and quality. Soil and in-season plant tissue testing for nitrogen status are a time consuming and expensive process. Real time sensing of plant nitro...
Ebrahimi L, TanhaMaafi Z, KarbalaeiKhiavi H, Didehbaz G, Azarmi Y and Zamani R (2019) Distribution and population density of cereal cyst nematode in Ardabil province. Plant Pathology Science 8(2):9-15. DOI: 10.2982/PPS.8.2.9 Introduction: Cereal cyst nematodes (CCN), Heterodera species, are important parasitic nematodes of cereal. Potato cyst nematodes (PCN), Globodera species, are also seriou...
A field study was conducted at the Zabol Agricultural Research Center during the years (2003-2004) to investigate the effect of irrigation with treated municipal wastewater on the yield and quality of wheat and some soil properties. Irrigation treatments were: T1: Irrigation of wheat with well water during entire period of growing season T2: Irrigation of wheat with well water until the begging...
urea is the most common form of nitrogen fertilizer used in sugar beet cultivation. urea has a high solubility and its losses are high and consequently its efficiency is low. it is supposed that urea solubility can be limited and its efficiency can be increased by using slow-release nitrogen fertilizers. by conducting an experiment in three important sugar beet cultivation areas of khorasan pro...
A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
In wheat, tillering and water-soluble carbohydrates (WSCs) in the stem are potential traits for adaptation to different environments and are of interest as targets for selective breeding. This study investigated the observation that a high stem WSC concentration (WSCc) is often related to low tillering. The proposition tested was that stem WSC accumulation is plant density dependent and could b...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
