Abstract: Textile industries release large volumes of dye wastewater that contain different dyes. Azo dyes contain strong N=N bond which are not easily broken by conventional methods. The discharge of this type of wastewater to natural watercourse can pose serious environmental impacts to aquatic life and man.A study was carried out to investigate the effects of process parameters on the electrochemical treatment of textile dye wastewaterfrom a Kenyan Textile Factory using stainless steel as anode material. Two model dyesnamely C.I. Reactive Red 76 (RR) and C.I. Disperse Blue 79(DB)obtained from Rift Valley Textile Factory (RIVATEX) in Kenyawere used for the study.The process parameters........

Abstract: A study on the effect of different aeration rates on the speed of composting process was carried with mixtures of cattle manure and three different carbon sources (sawdust, rice pods and sunflower husks) under controlled laboratory conditions. The performance characteristics of composting process were evaluated in terms of the evolution of temperature (T), pH, electrical conductivity (EC) and organic matter (OM) content. The single, one-time filling of the composting reactors with the compost mixture showed better performance characteristics over the gradual filling of the reactors. The aeration for 15 min/hour at the rate of 50 L air/min provided sufficient quantity of O2 for aerobic conditions in the composting mixtures. The compost mixtures with sunflower husks maintained longer thermophilic phase with higher average daily temperatures in comparison to the other two bulking agents.

Abstract: Parkinson disease is a chronic and progressive neurodegenerative disorder characterized by muscle rigidity, tremor and bradykinesia. The central aspect of Parkinson disease involves dysmetabolism of specific proteins resulting in aggregation, aborted protein degradation and/or formation of Lewy bodies. Parkinson disease involves the progressive loss of dopamine-containing neurons from the substantia nigra. The study of involvement of a protein named alpha synuclein in disease and the ligands targeting it, to possibly find a drug to cure the disease. Mutation in α-synuclein can lead to misfolding, aggregation and resistance to protein degradation. In silico approach to design a drug for.......

Abstract: Most herbal medicines and their derivative products were often prepared from crude plant extracts, which comprise a complex mixture of different phytochemical constituents. The chemical features of these constituents differ considerably among different species. GC-MS method used for the analysis of the obtained extracts can be an interesting tool for testing the amount of some active principles in herbs used in various industries. The aim of this study was to carry out for identification of bioactive compounds from the methanolic extract of Abelmoschas moschatus flower by Gas chromatography and Mass spectroscopy (GC-MS). GCMS analysis of methanolic extract was done by.......
