cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
در مدل نیرو- فشار، نیرو (x) و فشار (y)، به عنوان متغیرهای تصادفی در نظر گرفته می شوند و قابلیت اعتماد یک مولفه در یک دوره، به صورت احتمال بیشتر بودن نیرو از فشار در طول دوره یعنی p(y<x)، تعریف می شود. هدف اصلی این پایان نامه، بررسی برآورد پارامترهای شکل، مکان و مقیاس و پارامتر r= p(y<x) زمانی کهx وyدو متغیرتصادفیاز توزیع وایبل سه پارامتری با پارامترهای شکل و مکان یکسان، اما دارای پارامتر مقیاس...
OBJECTIVES To understand the characteristics of women physicians who work reduced hours in dual-earner couples and how such work schedules affect the quality of the marital role, parental role, and job role, as well as indicators of psychological distress, burnout, career satisfaction, and life satisfaction. METHODS Survey of a random sample of female physicians between 25 and 50 years of age...
BACKGROUND Some small controlled studies have found that dawn simulation is effective in treating seasonal affective disorder (SAD). With a larger sample size and a longer duration of treatment, we compared dawn simulation with bright light therapy and a placebo condition in patients with SAD. METHOD Medication-free patients with SAD were randomly assigned to one of three conditions: bright l...
The sunlight has an important role in metabolism of calcium ( Ca) and phosphorus ( P). The sunlight has different effects in different places. Therefore the pattern of metabolic disease depends upon geographical place. In this investigation two groups of workers( one group working in shadow and the other under the sunshine) were chosen as control and experimental groups respectively.these two ...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
در مدل فشار - نیرو، فشار (y) و نیرو (x)، به عنوان متغیرهای تصادفی در نظر گرفته می شوند و قابلیت اعتماد یک مولفه در یک دوره، به صورت احتمال بیشتر بودن نیرو از فشار در طول دورهp(y<x)، تعریف می شود. هدف اصلی این پایان نامه، بررسی براورد r=p(y<x), زمانی کهx و y دو متغیر تصادفی از توزیع بور نوع xii دو پارامتری هستند، می باشد. توزیع دو پارامتری بور نوع xii، که اولین بار توسط بور (19...
