The purpose of this study was to investigate cadmium adsorption through Freundlich and Langmuir equations in sediments of Karun River in three hydrometric stations (5th Ahvaz Bridge, Darkhovin and Khorramshahr) in the low-water and high-water seasons. Fitting of data from experiments on cadmium absorption to Freundlich and Langmuir equation showed they are compatible. According to the conducted...

نامساوی ها یکی از مهمترین حوزه های پژوهشی آنالیز ماتریسی هستند که از ابتدا مورد علاقه بسیاری از ریاضی دانان بوده و کاربردهایی در علوم مختلف از جمله محاسبات علمی، نظریه سیستم و کنترل، تحقیق در عملیات، فیزیک ریاضی، استاتیک، اقتصاد و مهندسی دارد. نخستین بار در سال $1934$ کتاب تقریبا جامعی با نام "نامساوی ها" cite{h} توسط هاردی، ltrfootnote{g. h. hardy} لیتل وود ltrfootnote{e. little...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...

this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...

this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...
