Research ArticleOpen accessIn the abstractEvaluation of Electricity Product by Increasing Water Volume During FreezingA. Arab, B. Alinaghi, M. R. RezaieElectricity production process by the use of water expansion during freezing. By use of a closed volume such as piston and cylinder. The volume increase of ice could be transformed linearly and cause piston displacement, by the use of cold resource and heat resources. This process is possible where boarding temperature difference is high and water temperatures reach below 0°C … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Simulation of a Turbulent Lean, Premixed Combustion with an Explicit Algebraic Stress ModelWilliam Vicente, Martín Salinas-Vázquez, Eliseo Martínez, Alejandro RodríguezA computational model is used in the present paper to study the influence of the turbulence modeling on the chemical species in a turbulent lean premixed flame. The simulated configuration is about a lean, premixed bluff-body-stabilized flame with a recirculation zone. To achieve the objectives, three different models were used for turbulence modeling as listed next: 1) standard k-ε, 2) … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,316 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsumer's Acceptability Estimation of Cold Preserved Malaysian Freshwater PatinA. S. Mokhtar, K. A. Abbas, S. M. Sapuan, M. M.H. AhmadThe study presents an attempt to correlate the consumer acceptability of Malaysian Patin fish with the storage time and temperature. A batch of typical fresh fishes was cut into regular slices (samples), which were wrapped and distributed evenly to four cold stores by 0, 3, 5 and 10°C storage temperature for a period of 28 days. During the course of … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractBinding of the scutellarin to albumin using tryptophan fluorescence quenching, CD and FT-IR spectraJianniao Tian, Jiaqin Liu, Zhide Hu, Xingguo ChenThe binding of scutellarin with bovine serum albumin (BSA) was investigated at three temperatures, 296k, 310K, and 318K, by the fluorescence, circular dichroism (CD) and fourier transform infrared spectroscopy (FT-IR) at pH 7.40. The binding parameters were determined by Stern-Volmer equation. The thermodynamic parameters were calculated according to the dependence of enthalpy change on the temperature as follows:ΔH0 and ΔS0 … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 13,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractFurther Improvements in Temperature Calculation During Cooling of Fish PackagesF. A. Ansari, K. A. Abbas, J. Bakar et al.In an earlier study, it was demonstrated that the empirical approach used to calculate the surface film conductance resulted into a higher value compared to those obtained from the other methods available in the literature. During further investigations, surface film conductance values were found to gradually decrease with a fall in temperature. When this non-linear variation was used to develop … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,848 accessesView PDFCite
