Biological assessment of river Haji Abad (Hormuzgan province) Using Macrobenthic Community Structure
This study aimed to investigate the population structure of benthic communities in Haji Abad River, West of Hormuzgan province. The study was conducted from October 91 till September 92. The three sites were determined based on regional topography and large benthic fauna. Sampling was performed monthly using a 500 micron Surber sampler with three replicates at each station. Samples were fixed i...
Large quantities of radiopharmaceuticals prescribed for treatment and diagnosis are excreted through kidney. Therefore, radiation unwanted dose is created in kidney. As a result, exact calculation of prescribed radiopharmaceuticals amount is important. Monte Carlo method is used for simulation of radiation transport in body due to random nature of radiation. In this research, for the first time...
As methods for analysis of biomolecular structure and dynamics using nuclear magnetic resonance spectroscopy (NMR) continue to advance, the resulting 3D structures, chemical shifts, and other NMR data are broadly impacting biology, chemistry, and medicine. Structure model assessment is a critical area of NMR methods development, and is an essential component of the process of making these struc...
A critical element in the any repair or upgrading project is the need to assess the condition of the structure. This assessment is needed to establish the existing condition of the structure and to plan for its repair. Secondly, means to assess in real time the progress of the repair are required especially when techniques such as grouting are being used. Finally, an assessment of the modified ...

فرض کنید (r, ??) یک حلقه موضعی منظم باشد، و یک حلقه موضعی آرتینی باشد. در این تحقیق به محاسبه کران های بالا و پایین برای تعداد (i)?? ( اعضای مجموعه مولد مینیمالi ) می پردازیم و در حالتی که به کمک حلقه مدرج وابسته به a و تابع هیلبرت آن، قضیه ساختاری برای این حلقه ارائه می دهیم. ایده اصلی این پایان نامه از مقاله j. elias, g. valla, structure theorems for certain gorenstein ideals, michigan math...
our main objective in the present study was to assess the spatial variation of chemical and physical water properties. prior to the design of groundwater quality monitoring networks, it is essential to investigate the spatial structure of the groundwater quality variables. a case study is presented which used ground water quality observations from groundwater domestic wells in the dameghan, ira...
in the last few decades, iran has experienced sharp fertility decline. studies indicate that women have a major role in childbearing; therefore, their empowerment and autonomy will lead to changes in their fertility behavior. this paper examines the relationship between family power structure and fertility behavior in the tehran city. the data is collected from around 400 women in tehran who ar...
