To estimate the biomass and secondary production of macrobenthos in Khore-e-Mousa creeks, 216 sediment samples were taken. The sampling period started in 1996 and terminated in 1997. A bimonthly sampling strategy was adopted. The samples were taken by Van-Veen grab (0.1 m2) from the beginning, middle and end of each creek (Khor). To estimate the biomass of the macrobenthos, the Crisp method (...
introduction oxidative stress is an inevitable consequence of intensive production due to mismatched balance between free radical production and natural antioxidant capacity of animals. reactive oxygen species (ros) refers to a group of free radicals produced by oxidative energy cycle and also recently demonstrated to be as a weapon for macrophage cells. moreover, feed processing phenomena such...
Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...
MCM-41 mesoporous silica is synthesized based on a self assembly method, using a quaternary ammonium template, CTAB for the adsorption of sulfur compounds from model oil (1.0 mmol/l DBT in dodecane solution). Then the adsorption capability of MCM-41 assembled on the surface of bacterium Rhodococcus erythropolis IGTS8 is examined regarding the improvement of the biodesulfurization process of...
تحلیل پوششی داده ها به عنوان یک علم نوپا به ابزاری برای اندازه گیری کارایی در آمده است. تحلیل پوششی داده ها به بررسی و ارزیابی واحدهای تصمیم گیرنده که یک یا چند ورودی را برای تولید یک یا چند خروجی مصرف می کنند می پردازد. از مشخصه های اصلی تحلیل پوششی داده ها حساس بودن آن نسبت به داده ها می باشد بدین معنی که عدم دقت در جمع آوری داده ها باعث به دست آمدن نتایج نادرستی می گردد. از جمله کاربردهای ان...

the radioisotope 67ga (t 1/2 = 78 h) in extensively used as single photon marker for detecting the presence of malignancy and the diagnosis of inflammatory diseases. the high tumor specificity of carrier-free 67ga make it one of the most interesting radionuclides in nuclear medicine for in vivo scanning studies.67ga is a cyclotron produced radioisotopes and is one of the radiopharmaceuticals wh...
