Background: The immune antigen of Bacillus anthracis is a protein that can attach to the surface receptor of all human cells. At the surface of cancer cells, there is a receptor that activates the uPA (Urokinase plasminogen) that do not exist in normal human cells. Objectives: The aim of this study was changing the location of the attachment of the PA gene by a dir...

hydrates are crystalline compounds similar to ice, with guest molecules like methane and ethane trapped inside cavities or cages formed by the hydrogen bounded framework of water molecules. these solid compounds give rise to problems in the natural gas oil industry because they can plug pipelines and process equipments. low dosage hydrate inhibitors are a recently developed hydrate control tech...

a colorimetric method for detection and assay of mustard gas in urine after addition of thymolphthalein is reported. the detection limit was 80 ng/ml of llrine. mustard gas could also be detected in urine after extraction with gas chromatography using fid detector. the detection limit was 10 ng/ml. in addition, thiodiglycol, a metabolite of mustard gas, could be converted to mustard with concen...

the natural gas consumption in iran has been continuously increasing due to several reasons including low prices of natural gas, development of gas supply networks, people’s salary increase, incorrect consumption culture and the increase of national economy growth.  although, the global natural gas consumption has increased by 38% since 2001, the national consumption in iran has increased by 11...

the present study was carried out to determine the nutritive value of white varieties of grape pomace (gp) and raisin vitis leaves (rvl), using nylon bags and gas production techniques. tow fistulated whether with average body weight of 45±2 kg were used. the amount of gas produced was measured at 2, 4, 6, 8, 12, 16, 24, 36, 48 and 72 h times and degradation was measured using nylon bags up to ...

residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...

Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...
