Research ArticleOpen accessIn the abstractDetermination of the Exergy of Four Wheat StrawsYaning Zhang, A. E. Ghaly, Bingxi LiExergy is a measurement of how far a certain material deviates from a state of equilibrium with the environment. It is a useful tool for improving the efficiency of energy-resource use. The exergy values of four wheat straws (Absolvant, Max, Monopol and Vuka) were determined in this study. The effects of physical and chemical properties (moisture content, ash content, LHV … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,494 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Basin Solar Still by Adding Magnetic Treatment Unit and Double Glass Cover Provided with WaterAsaad Rehman Saeed Al-HilphyThe basin solar still was developed by adding a magnetic treatment unit, it’s energy 0.12 Tesla and two layer of glass provided with water between them. The study was conducted by testing the device by using magnetic water + double glass provided with water, non magnetic water + double glass cover, magnetic water + single glass cover, non magnetic water … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Analysis in Handling and Storage of Petroleum ProductsGuarascio Massimo, Lombardi Mara, Massi FedericaIncrease in productivity and technological system innovation have resulted a boost in the specific activity of use and handling petroleum Products the chemical and physical properties of petroleum products represent an advantage when they are used for its own uses, but may result in accidental scenarios which can cause serious damage to people and to environment.

Research ArticleOpen accessIn the abstractComprehensive Investigation into the Exergy Values of Six Rice HusksYaning Zhang, A.E. Ghaly, Bingxi LiExergy is a measurement of how far a certain system or material deviates from a state of equilibrium with the environment and it is a useful tool for improving the efficiency of energy-resource use. Based on the previous work, the exergy values of six rice husks were investigated in this study. The effects of physical and chemical properties were also … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 10 Jun 2013 · 7,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegumming of Raw Silk Fabric with Help of Marine Extracellular ProteaseDas Sumana, Mathummal Sudarshan, Ashoke Ranjan Thakur, Shaon RayChaudhuriProtease secreting microbe was isolated and characterized on the basis of their morphological, biochemical, physiological and 16S rDNA based molecular properties. The extracellular protease was quantified and characterized. Protease was used for different time (4, 8, 12 and 24 h) at different temperature (RT and 37°C) for optimization of the degumming process for raw silk fabric with enzyme dosage (0.2-1 … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 9,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metal Contamination of Soils and Water Resources Kettara Abandoned MineManuel Valiente, Gustavo Perez, Marta Avila et al.Problem statement: Metal mining; together with mineral smelting and processing, have contaminated the environment surrounding mine areas throughout the world exceeding natural background concentration.
