In this article, we used SuperMc 3.2 Software for have studied two models of welding radiographic techniques that are more common in radiographs (Dobell Walls and Single Image (DWSI) and Single Wall and Single Image (SWSI) technique) , without the use of a collimator and in terms of radiation risk and radiation safety. According to results, Due to the lack of a collimator, the risk of radiation...
در این تحقیق به منظور مطالعه زیست چینه نگاری و محیط رسوبی سازند آسماری یک رخنمون در برش خرامه (جنوب شرق شیراز) به ضخامت 160 متر به همراه 70 مقطع نازک مورد مطالعه و بررسی قرار گرفت. برش خرامه از نظر سنگ چینه شناسی شامل، آهک متوسط تا ضخیم لایه خاکستری کرم رنگ تا نخودی می باشد. بر اساس زیست چینه نگاری 18 جنس و 21 گونه از روزن داران بنتیک شناسایی گردید. در برش خرامه چهار بیوزن معرفی گردید. 1- numm...
Introduction It is recognized that physical and chemical interactions between adjacent ground water and surface water bodies are an important factor impacting water budget and nutrient/ contaminant transport within a watershed (Winter et al., 1998). This observation is also of importance for hazardous waste site cleanup within the United States, since about 75% of sites regulated under the Reso...

makran subduction zone (msz) offshore of iran and pakistan is one of the most tsunamigenic sources in the indian ocean. historically, the msz has generated some tsunamigenic earthquakes like that of 28 november 1945 with the death tool of more than 4000 people along the coasts of iran, pakistan, india, and oman. in this study, the tsunami hazard associated with the msz is investigated. at first...
Sperm competition represents an important component of post-copulatory sexual selection. It has been argued that the level of sperm competition declines in birds towards the equator. However, to date, sperm competition estimates have been available mainly for avian species inhabiting the northern temperate zone. Here we apply a novel approach, using the coefficient of between-male variation (CV...
experiencing a tremendous change that can be attributed to a combination of demographic changes, technological advances, and broadening service offerings. The Wealth Management industry is in the midst of a renaissance.

In the Savannah region of West Africa, the highly variable rainfall and poor soils have been shown to dierentially aect the yield potential of various crops. The paper applies a simple risk programming model to assess the eects of price and yield risk on the incomes of smallholder farmers in northern region of Coà te d'Ivoire. The analysis showed that by considering price and yield risks, it...
PURPOSE To evaluate risk factors for the incidence and progression of age-related macular degeneration (AMD) in a racially heterogeneous, geriatric population. METHODS Subjects (n = 2240) aged 65 to 84 years underwent 2 examinations separated by 2 years, of which 1937 subjects (85%) were included in this report. Fundus photographs were performed at each examination and were graded by trained ...
Background & Objectives: Assessment of physical risk factors related to musculoskeletal disorders is performed by different methods including observational methods. Validity of these methods are important in workplaces. The purpose of this study was to investigate the reliability of the Washington States ergonomics checklist as an observational method.
