استفاده از سوخت هیدریدی در رآکتور به عنوان سوخت هسته ای، منجر به کاهش چشمگیر دمای سوخت و به تبع آن کاهش انتشار گازهای حاصل از شکافت که خود منجر به کاهش تورم ایجاد شده در سوخت در زمان کار آن می شود. در این تحقیق فاصله بین سوخت و غلاف بوسیله فلز مذاب پر شده و از برنامه mcnpx 2.6 به منظور محاسبه discharge burn-up استفاده گردید. دو نوع سوخت هسته ای اکسیدی و هیدریدی در دو نوع رآکتور با میله های سوخت...
فشارهای الکتریکی و مکانیکی و ... که در دستگاههای فشارقوی بروز می کنند، ممکن است باعث معیوب شدن سیستمهای عایقی اینگونه دستگاهها شوند. در اثر ایجاد اینگونه مشکلات ، استقامت عایقی این سیستمها کاهش یافته و در نتیجه ممکن است باعث شکست مکانیکی (که ناشی از فشارهای مکانیکی می باشد) و یا باعث بروز پدیده تخلیه الکتریکی (discharge) که ناشی از فشارهای الکتریکی می باشد، شود. در اثر بروز تخلیه های الکترکی بت...
For efficient use of water, accurate measurement of flow in (field/laboratory) channels is required for many water resource projects. The present work is aimed to study the flow characteristics of a twin plate weir (two sharp-crested plates are placed one behind the other at some distance) under free and submerged flow conditions. Experiments are performed with four spacing of the twin plate we...
this survey has been conducted to indicate the positive effects of implementing neonates continuous care patterns on their physical health as well as early diagnosis and decrease of complications in 6 weeks after delivery. this quasi-experimental study has been conducted on 118 mothers and their neonates in one maternity hospital in iran. neonates were assigned in control and experimental group...
in postpartum departments the skills and experience of doctors and midwives will overlap together but it is not sufficiently recognized . little importance to the ability of midwives will reduce the scope of their responsibilities and decision-making power will be taken from them , also this will result in demoralization and decreasing job satisfaction. in this situation work load of new physic...
objective: early discharge of newborns is essential because of social, economic an medical reasons in our area, but it increases readmission rates especially for hyperbilirubinemia. hence, predicting the high risk neonates for subsequent hyperbilirubinemia is required. this study was designed to investigate which level of total serum bilirubin (tsb) at the first day could be used to predict hyp...
Suspended sediment transport by rivers is important in water quality of cities and villages fed by certain drainage basins. On the other hand, the effective discharge refers to discharge that transports the most sediment over long time and controls the shape of river bed. Therefore, determination of effective discharge for suspended sediment transport and analysis the variation of effective dis...
