Research ArticleOpen accessIn the keywordsModeling of Particle Separation in Bends of Rectangular Cross-sectionBingtao ZhaoA new theoretical model for predicting particle separation efficiency in bends is developed based on the investigation of flow pattern, the critical particle size separation theory and the boundary layer separation theory. The radial particle concentration gradient, instead of the usually assumed uniform radial particle concentration within the bends, is considered in this mathematical model. The local particle concentration and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Immunomagnetic Separation Method for Viable Salmonella Typhimurium Detected by Flow CytometryShakil Ahmed, Horst-Günter Rubahn, Helmut ErdmannA very small number of bacterial pathogens may have fatal effects on food safety. In spite of having great advancements in bioanalytical methods, most of the accepted detection methods are still cultivation based and thus time consuming. This leads to an intense need for efficient and rapid methods for detection of food-related bacteria. In this study, a flow cytometry based … …OnLine Journal of Biological Sciences, Vol. 16, Issue 4 · 25 Nov 2016 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow Dynamic Behavior of Fish Oil/Silver Nitrate Solution in Mini-Channel, Effect of Alkane Addition on Flow Pattern and Interfacial TensionKirubanandan ShanmugamThe mini-fluidic contacting system is developed as process intensification platform as an attractive alternative for existing liquid-liquid extraction system for separation of Omega 3 PUFA from using Aqueous 50% Wt. Silver nitrate solution. To improve the performance of extraction in mini-fluidics, it is necessary to study the flow-dynamic behavior of fish oil silver nitrate system in the channel. Moreover, different … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 26 Feb 2016 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Water-Soluble Polymers for Extraction Separation of Amino Acids of Various StructuresNadezhda Yakovlevna Mokshina, Dmitry Vladimirovich Bykovskiy, Gennadiy Valentinovich Shatalov, Oksana Anatolievna PakhomovaThis article actualizes the task of developing new methods for extraction separation of amino acids for the analysis and purification of target components in the production of food supplements, pharmaceuticals, agricultural products and cosmetics; it also presents the extraction separation results for binary mixtures of histidine, proline and methionine using water-soluble homo- and co-polimers with various molecular weight values. We … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 10 Dec 2015 · 6,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Intensification for Production and Recovery of Biological ProductsHamideh Vaghari, Maryam Eskandari, Vahideh Sobhani et al.Bioprocesses are important biological reactions which need several sophisticated methods and equipment to produce many novel and important compounds which some of them are traditionally produced by synthetic chemical reactions. In bioprocesses, the products are often produced in a dilute environment and finally they require a high purity. Because of that, downstream processes are usually included a large number of … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 29 Jan 2015 · 8,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractSulfur Recovery from Acid Gas Using the Claus Process and High Temperature Air Combustion (HiTAC) TechnologyMohamed Sassi, Ashwani K. GuptaSulfur-bearing compounds are very detrimental to the environment and to industrial process equipment. They are often obtained or formed as a by-product of separation and thermal processing of fuels containing sulfur, such as coal, crude oil and natural gas. The two sulfur compounds, which need special attention, are: hydrogen sulfide (H2S) and sulfur dioxide (SO2). H2S is a highly corrosive … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 17,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of The Bubble Foam Separation Technique To Extract Protein From WheyMohammed MatouqSeparation of proteins from whey; namely α- Lactoglobulin and β- Lactalbumin was obtained using the bubble foam column technique. Two types of whey were conducted in this study; yogurt whey and cheese whey. The effect of gas flow-rate and the height of the whey (liquid holdup) inside the column were studied at room temperature and at constant pH of whey. … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,351 accessesView PDFCite
Research ArticleOpen accessIn the abstractReliability Evaluation of Distributed Computer Systems Subject to Imperfect Coverage and Dependent Common-Cause FailuresLiudong Xing, Akhilesh ShresthaImperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantly to the overall system unreliability. … …Journal of Computer Science, Vol. 2, Issue 6 · 28 Sep 2006 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractEOS: Evolutionary Overlay Service in Peer-to-Peer SystemsL. I. Zhijun, Liao MinghongThe peer-to-peer (P2P) systems nowadays can be mainly classified into two categories: structured and structure-less systems based on their overlay organization. The structured systems can achieve determinate efficiency due to their rigorous structure with the cost of losing robustness and vice versa. We provide a semi-structured overlay based on the separation of routing structures and overlay organizations in this paper … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,349 accessesView PDFCite
