Hemicelluloses of Wheat
In 1890, 2 years before the term ^^hemicellulose" was introduced into chemical Uterature by Schulze (12) j^ Allen and ToUens (1) extracted wheat straw with alkali and obtained a product that on hydrolysis afforded ¿-xylose. In 1901 Salkowski (11) extracted wheat straw with boiling 6-percent sodium hydroxide solution and showed that the xylan could be precipitated from the alkaline extract by me...
متن کاملSequential fractionation of feruloylated hemicelluloses and oligosaccharides from wheat bran using subcritical water and xylanolytic enzymes†
Wheat bran is a major by-product of cereal production that still has limited use for advanced nutritional and material applications. A sequential process using subcritical water, membrane filtration and selective enzymatic treatments has been designed for the combined fractionation of functional high molar mass hemicelluloses (over 10 g mol) and oligosaccharides from wheat bran. This process no...
متن کاملModeling the performance of a membrane bioreactor controlled by air sparging.
A membrane bioreactor (MBR) combines biological treatment with the membrane separation technology. To improve the understanding of the MBR processes and know how, many researches were carried out suing the trial and error method and build the knowledge based on experiments. The problem with such an empirical research is that the results are difficult to generalize due to the complexity of the s...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولTechno-Economic Assessment of Different Inlet Air Cooling Systems in Warm Dry & Wet Climate Stations
Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...
