Research ArticleOpen accessIn the abstractPotential Environmental and Health Impacts of High Land Application of Cheese WheyA. E. Ghaly, N.S. Mahmoud, D.G. Rushton, F. ArabA laboratory scale experiment was carried out to study the transformation and transport of nitrogenous compounds in soils receiving high application rates of cheese whey (twice the nitrogen requirement for crops). The experimental apparatus consists of 36 soil columns constructed of 20 cm inside diameter PVC pipes. Three types of soil (sandy loam, loam and sandy clay loam) and three … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,158 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Use of Biosensors to Analyse a Soldier’s Stress LevelJosé Miguel Martinho Silva, Ricardo A. Marques Lameirinhas et al.Currently and increasingly, biosensors are present in our daily lives, even if tendentiously and imperceptibly. As such and given their importance, the scientific community is clearly interested in making progress in this research field. This study is part of the study of biosensors using pre-gelled electrodes and was focused on the analysis of the ability to extract information on the … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 1 Mar 2024 · 4,982 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of Binary and Ternary Models in Powder Packing Density for Additive Manufacturing ApplicationsTaher M. Abu-Lebdeh, Oluwatobiloba Adetokunbo KalejaiyePowder packing is a very important aspect of additive manufacturing (3-D printing), as it directly impacts the final physical and mechanical properties of the printed objects. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed product, which also contributes to the surface finish. In order to achieve the densest packing for a powder, different sizes … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 15 Jun 2021 · 7,284 accessesView PDF Cite

The hydrogen storage materials are one of the principal challenges that must be met before the development of a hydrogen economy. Among all materials studied an important class that could have a future, in particular in portable applications, … …Energy Research Journal, Vol. 8, Issue 2 · 7 Aug 2017 · 7,082 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHeat Transfer and Effectiveness Analysis of a Cross-Flow Heat Exchanger for Potential Energy Recovery Applications in Hot-Humid ClimateA.R.S. Masitah, Mardiana I Ahmad, Y.M. YatimThis paper presents heat transfer and effectiveness analysis based on a physical model of a cross-flow heat exchanger. Using the model, the transferred heat and effectiveness (ε) in terms of temperature and NTU-method are calculated for both hot and cold streams. From the analyses, it is found that as air velocity increases, the transferred heat through heat transfer plates increases. … …Energy Research Journal, Vol. 6, Issue 1 · 15 May 2015 · 13,621 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIsolation and Physical Characterization of Hydrophobin-Like Proteins (HLP) from Aerial Conidia of Metarhizium Anisopliae Var. AnisopliaeD. S.B. Kiong, Choon Fah J. Bong, P. J.H. KingThe aim of this study was to isolate and physically characterized Hyrophobin-Like Proteins (HLP) from the aerial conidia of two local isolates of Metarhizium anisopliae var. anisopliae, namely, TA and LR2. The protein samples were isolated based on their insolubility in hot Sodium Dodecyl Sulfate (SDS). The SDS-insoluble proteins were then purified in cold 98% formic acid and performic acid. … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 29 Jan 2015 · 7,778 accessesView PDF Cite
