Removal of PAHs from n-Paraffin by Modified Clinoptilolite
The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. Ag+, Fe3+…). Nat...
متن کاملHeteropolysaccharide Formation by Arthrobacter viscosus Grown on Xylose and Xylose Oligosaccharides.
Arthrobacter viscosus NRRL B-1973 produces its viscous extracellular polysaccharides (EPS) when grown on media containing xylose or enzymatic xylan hydrolysates. Crude EPS formation from xylose averaged 12 g/liter when initial culture pH was adjusted to 8.0 and total nitrogen was limited to 0.03%. Purified EPS from pentose and hexose substrates were analyzed for their monosaccharide, acetyl, an...

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Extracellular lipids of Cladosporium (Amorphotheca) resinae grown on glucose or on n-alkanes.
Cladosporium (Amorphotheca) resinae was grown in shake culture on glucose, n-dodecane, or n-hexadecane. Growth was most rapid on glucose, and more acid accumulated in the medium than in n-alkane-grown cultures. Neutral lipid was the major lipid fraction and triglycerides were the only extracellular neutral lipids detected. Dodecanoic (lauir) acid was the predominant fatty acid (greater than 60%...
