abstract introduction: heat stress risk assessment, as a harmful agent at workplace, is essential for controlling heat strain and heat stress effectively. this study is concerned with the relationship between physiological strain index (psi) and wet bulb globe temperature index (wbgt) in women in the climate chamber . methods: this experimental study was carried out on 36 healthy females in sit...
Nanotechnology is gaining tremendous impetus in the present century due to its capability of modulating metals into their nano size, which drastically changes the chemical, physical and optical properties of metals. The extremely small size of nanoparticles help them to occupy a greater surface area and hence a better accessibility and targeted action. Nanoparticles can overcome existing drug r...
a survey was carried out in five provinces of iran (kerman, sistan and baluchestan, hormozgan, khorasan and yazd) for the presence of alfalfa mosaic virus (amv) sero-types in alfalfa during 2002 to 2003. the number of samples collected was 250, represent-ing the diversity and geographical distribution of amv in these areas. diagnosis was car-ried out using polyclonal (pabs) and monoclonal (mabs...
background the search for novel antibiotics continues to be of immense importance in research programs around the world for pharmaceutical, industrial and agricultural applications. filamentous soil bacteria, belonging to the streptomyces genus, are widely used as an important biological tool for their ability to produce a wide range of novel secondary metabolites, such as “antibiotics”. object...
background : in many jobs, individuals are exposed to thermal stress, and thus, evaluation of heat stress is necessary. this study was conducted with the purpose of investigating the relationship of perceptual strain index (pesi) with other heat indexes under hot laboratory conditions. methods: this empirical-experimental and cross-sectional study was performed in 5 different temperatures (21 º...
stressful life events may play an important role in coronary heart disease and sudden cardiac death. this study was performed to compare the frequency of stressful events and mental strain in patients with acute myocardial infarction (mi) and normal population. a case-control study was performed on 50 survivors of mi and 50 controls with no evidence of cardiovascular disease, matched by age, ge...
چکیده: پژوهش حاضر با هدف بررسی راهکارهای بیولوژیک در کاهش اثرات منفی شوری بر گیاه گندم به بررسی جنس و ترکیب تعدادی از سویه های باکتریایی در دو رقم مقاوم(کویر) و حساس(قدس) گیاه گندم پرداخته است. به این منظور آزمایشی بر مبنای فاکتوریل در قالب طرح پایه کاملا تصادفی درسه تکرار و هفتاد و دو تیمار در دو شرایط جداگانه آزمایشگاهی(آزمایش جوانه زنی) و گلخانه ای (بررسی اثرات مورفولوژیکی، فیزیولوژیکی و بی...
