Municipal solid waste management is a major challenge, especially in metropolises. This research focuses on a non-technical issue in municipal solid waste management named municipal solid waste separation at the source and seeks to find the best policy in terms of model results. Source separation for recycling has been recognized as a way to achieve sustainable municipal solid waste (MSW) manag...

N.sitophila was grown under controlled conditions of solid state and submerged fermentation on Sago hampas. The optimum conditions of protein enrichment previously established for sugar beet pulp was used for this study. Under this condition the protein content of Sago hampas under solid state increased from 1.4 to 14.45% (W/W) whereas for Sago hampas and Sago starch, the protein content under ...

     Ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (PEG), polyvinylpyrrolidone (PVP), eudragit RS PO, eudragit RL PO and hydroxypropylmethylcellulose (HPMC) as carriers to improve physicochemical characteristics of ibuprofen. The prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissoluti...

Palm oil solid wastes consist of cellulose, hemicellulose and lignin. In this study, a single stage of acid hydrolysis process of palm oil empty fruit bunch (EFB) for production of fermentable sugar was carried out under moderate temperature (45°C) and ambient pressure. The effect of four different process variables such as solid size, HCl concentration, solid percentage and temperature were in...

the copper(ii) complex [cu(pic)2]·2h2o was synthesized with 2-picolinic acid (hpic) and copper acetate as reactants by room temperature solid-solid reaction. the composition and structure of the complex was characterized by elemental analyses, single crystal x-ray diffraction, x-ray powder diffraction, ft-ir spectroscopy and thermogravimetry-differential scanning calorimetry. the crystal struct...

objective(s):the present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. materials and methods:the hplc method was carried out by using a c18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...
