abstract mefenamic acid is a nonsteroidal anti-inflammatory drug (nsaid) that has analgesic,anti-infammatory and antipyretic actions. it is used to relieve mild to moderate pains. solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . poly allyl glycidyl ether/iminodiacetic acid-co-n, n-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

A solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using Aspergillus niger ATCC 9142. The Plackett Burman design (PBD) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial pH of substrate, methanol conce...

ABSTRACT: Using agricultural waste is one of the best ways to reduce the costs and the environmental pollution. Button mushroom´s stipe is a cheap by-product that is rich in nutrients for human nutrition. The purpose of this study is to compare the nutritional value of cap and stipe of button mushroom (Agaricus bisporus). The caps were separated from the stipes after harvesting and parameters s...

SnCl4/nano-sawdust was prepared as a carbohydrate-based catalyst containing of tin bearing cellulose units. The catalyst was characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS). The catalyst was applied successfully as a readily available, inexpensive, biodeg...

The effect of granular pressure on the fluctuation volume fraction is investigated experimentally in a gas–solid flow system. Granular compressibility, defined by response fractions pressure, also measured. It found that there exists critical beyond which transition from coexistence liquid-like phase and gas-like to homogenous fluids takes place. heterogenous characterized an abrupt change comp...
