Research ArticleOpen accessIn the abstractHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,372 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Comparisons of Anchovy Drying using Centrifugal and Gravitational Fluidized Bed TechniquesWatcharin Dongbang, Rungtawan WiwattanasirikulThe present study investigated experimental comparisons of anchovy drying using centrifugal and gravitational fluidized bed techniques; in addition, drying models and thermal efficiency were also investigated. In the first stage, fresh anchovy was dried with solar energy to reduce the initial moisture content from 81±1%wb to around 65%±1wb. In the second stage, the anchovy was dried with a dryer from … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 23 Apr 2015 · 7,351 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Canadian Regulations and Remediation Methods for Diesel Oil Contaminated SoilsD. G. Rushton, A E. Ghaly, K. MartinellDiesel fuel released into the environment can contaminate ground water, degrade potable water supplies and cause the collapse of fisheries. They are toxic to both animals and humans and can affect the liver, lungs, kidneys, and nervous system leading to cancer as well as immunological and reproductive effects. The objectives of this study were to review current Canadian regulations pertaining … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 8,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,982 accessesView PDFCite
