this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
background: persian gulf is a semi-closed environment which is affected by pollution from heavy metals. entrance of heavy metals to the water column and binding to sediment particles can affect the benthic organisms that can accumulate these materials in their body. noticing this ability, mussels are considered as bio-monitoring agents. methods: the pearl oyster, pinctada radiate, and sedi...
Introduction: Zoontic cutaneous leishmaniasis (ZCL) is one of the most important vector-born diseases in Iran, transmitted by phlebotominae sandfiles and its foci exist in different parts of the country. In Hormozgan province, south of Iran, cataneous leishmaniasis mainly reports from Hajiabad, Banda-Lengeh and Kahoorestan. This study is conducted to investigate epidemiology of leishmaniasis in...
Macrobenthos are benthic animals that live in or on the bottom sediments which used as a bioindicators to assess the presence of contaminants, in natural aquatic systems. This study aimed to achieve the relationship between sediment composition and macrobenthic communities, distribution. Sampling was done monthly in 2011-12 by a powerboat, and VanVeen grab with 0.04 cross section, were used for...
introduction: reverse osmosis (ro) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. the aim of this research was the performance study of reverse osmosis plants for water desalination in bandar-lengeh, iran. materials and method...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
