این پژوهش به بررسی همبستگی مثبت و معنیداری بین نسبت ارزش افزوده اقتصادی به سرمایه (EVA/Cap) با نسبت ارزش افزوده بازار به سرمایه (MVA/Cap) در بورس اوراق بهادار تهران از سال 1379 تا 1386 میپردازد. از رگرسیون خطی برای آزمون فرضیهها استفاده شده است. نتایج بررسی بیانگر وجود ارتباط و همبستگی مثبت و معنیدار بین EVA/Cap با MVA/Cap در تمامی شرکتهای مورد مطالعه بدون توجه به صنعت آنها و همچنین در تک تک صن...
Objective(s): The aim of the present study is to determine the effect of Chloramphenicol (CAP) on rat liver and small intestine. Effect of phenobarbital (PB) on CAP toxicity was also investigated. Materials and Methods: Rats were received CAP at doses of 0, 200, 400 and 600 mg/kg. Another group was pretreated with 80 mg/kg PB 30 min prior to administration of various doses...
Background and purpose: Cancer is one of the major health challenges in the world. The efficacy of current treatments is low but their side effects are high. Cold atmospheric plasma (CAP) is a new modality for cancer treatment. This study aimed to compare the cytotoxicity effect of CAP on the cell line models of common cancers and normal cells. Materials and methods: In this experimental study...
The electrocatalytic oxidation of captopril (CAP) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ISPT) using cyclic voltammetry (CV), chronoamperometry and square wave voltammetry (SWV). Also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for CAP were calculated. The mechanism of CA electrochemical behavior at the mo...
Background and purpose: Colorectal cancer (CRC) is ranked as the second most common cancer in men and the third most common cancer in women worldwide. Routine treatments have many side effects and little efficiency. The aim of this study was to investigate the effects of Cold Atmospheric Plasma (CAP) on epigenetic changes of some genes involved in CRC progression. Materials and methods: Prolif...

seed cap tightness is known to be highly associated with the low germinability of sugar beet fruits. despite, accomplishment of physiological phases of germination in germinating sugar beet seed with a tight cap, seedling emergence is usually suppress by the cap. as the seed coat (including the cap) is originated from ovary wall of the mother plant, seed cap tightness could be considered as one...
صنایع پتروشیمی با توجه به ترکیبات متنوع آن و نیز به واسطه دارا بودن فلزات سنگین، از پتانسیل ایجاد آثار سوء بر بهداشت و سلامت افراد و تخریب محیط زیست را برخوردارند. در این مطالعه اثرات زیست محیطی ناشی از فعالیت صنعت پتروشیمی تولید کننده pet- pta واقع در منطقه ویژه اقتصادی ماهشهر مورد بررسی قرار گرفته است. با توجه به اینکه عمده صنایع پتروشیمی موجود در این منطقه در مجاورت خورها احداث شده اند، آلود...
