Research ArticleOpen accessEvery word in the titleComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Useful Life of Lubricants Using Analytical Hierarchy Process (AHP) and Vector Projection Approach (VPA)Surachai Bovornsethanant, Somchai WongwisesProblem statement: In general, engine oil is usually changed as defined by car or lubricant manufacturers, which is according to mileage. However, it was found from past researches that, at the predefined mileage or timeframe, most lubricant is still acceptably usable and efficient. Approach: This research aimed to calculate useful life of lubricant in order to reach its maximum usefulness. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,640 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Contribution of Lube Additives to the Life Cycle Impacts of Fully Formulated Petroleum-Based LubricantsGiorgia Girotti, Andrea Raimondi, Gian Andrea Blengini, Debora FinoProblem statement: Previous applications of the Life Cycle Assessment (LCA) methodology to lubricants are not sufficiently detailed and comprehensive for R and D purposes and there are no LCAs of lube additives and fully formulated lubricants. The aim of this study is to integrate and expand previous LCAs of lubricants and to investigate on the contribution of lube additives to … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 9,359 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of a Refrigeration System Based on Nano-Refrigerants and Nano-LubricantsHudaElslam A. S. Mohamed, Unal Camdali, Metin ActasMost of studies reported that disperse nanoparticles into refrigerants and lubricating oils lead to improve a coefficient of performance, due to improvement of thermal physics properties of a pure fluid, which leads to reduced energy consumption. Using nanoparticles in a refrigeration system is associated with many difficulties such as the cost of preparing and obtaining a stable and homogeneous mixture … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 12 Aug 2021 · 7,164 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCondoms-As Sources of Extracellular Enzyme Producing MicrobesMadhusmita Mishra, Poulomi Nandy, Sarvani Debsarma et al.Problem statement: Condoms are widely used birth control measures which are made of natural latex or synthetic materials like polyurethane or polyisoprene as matrix with lubricants added to make them ready to use commodities. Absence of sterilization method along with presence of lubricant like petroleum jelly (that are applied on the outer surface), prompted the investigators to look for microbes … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE ADVERSE EFFECT OF STEEL PARTICLE CONTAMINANTS ON FATIGUE LIFE OF GREASE LUBRICATED BALL BEARINGSA. Stathis, Th. Costopoulos, D. Koulocheris, K. RaptisThe rating life of ball bearings is reduced when hard particle contaminants are present in the lubricant. Usually, this life reduction is taken into account in the calculation of modified rating life by using the contamination factor through a general characterization of the lubrication conditions. However, the impact of contaminant’s variables such as size, hardness and concentration level has to … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 14 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Transporting System Model for Oil RefineryRazman Mat Tahar, Waleed K. AbduljabbarProblem statement: Oil refineries are widely used to store various liquids and gases. Petroleum products are in high demand. Oil companies have abundant resources of petroleum products in pipelines and storage tanks. Approach: Included are storage tanks at retail gasoline station, home heating oil tanks, lubricant storage at automotive service facilities, propane tanks in all sorts of application, and oil … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistomorphochemical Studies on Accessory Glands of Iraqi Blackbuck (Caprus Hircus)Waleed J. A. Al-Kelaby, Wafaa Hadi Mousa AL-Hashem, Zahraa S. M. Al Kaabi et al.Thevarious species' male accessory genital glands vary and are intimately relatedto the pelvic urethra. These glands secrete nutritional substances, buffers,and mucous to increase volume, serve as lubricants, reduce the minor acidity ofvaginal contents and make the environment more hospitable to motile sperm. Thisstudy aims to study the histological and histochemical structure of the maleaccessory sex glands in caprine Iraqi breeds. … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 25 Nov 2022 · 5,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Ultra Violet Radiation on Polyethylene Packaged Water Exposed at Varying Conditions: Are we Drinking Micro-Plastics?James Matthew Anayo, Victor Eshu Okpashi, Ikechukwu N.E. OnwurahThe public is worried about how their health is impacted by microplastics in sachet water. This awareness has repercussion for water producing factories and public health organization in managing health hazard associated with microplastic ingestion. Many countries in Africa, with concern to Nigeria, the act of packaging water in polyethylene materials by water producing factories has become accustomed. These packaged … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 29 Jan 2018 · 9,915 accessesView PDFCite
