Results: Testing … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 8,344 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvaluation of Fuel Consumption and Exhaust Emissions During Engine Warm-upM. Al-HasanEngine exhaust emission and fuel consumption during warm-up period was experimentally investigated. Experiment was conducted on a four-stroke four-cylinder spark ignition engine alternatively equipped with CIS and EIS. Fuel consumption; and exhaust emissions included hydrocarbon, carbon monoxide and carbon dioxide were measured as a function of ambient temperature; i.e. 7, 25 and 40ºC. In order to simulate engine operation condition … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,417 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffect of Fuel Properties on Exhaust Emissions during Warm-Up ProcessRosli Abu Bakar, Beny CahyonoProblem statement: Increasing air pollutions the big problem form internal combustion engines. Several attempts have been done to get a cleaner combustion process, one of which is the use of fuel ethanol in gasoline engines. Approach: The addition of ethanol in fuel will be change fuel properties. Results: To know the effect of fuel properties on engine performance and emissions … …Energy Research Journal, Vol. 2, Issue 1 · 23 Jan 2012 · 7,278 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction and Quality in Dwarf Napier Grass Pasture Fertilized by Digested Effluent of Manure under Two-Years of Dairy Cow-Grazing in Warm Regions of JapanHadijah Hasyim, Ahmad Wadi, Yasuyuki Ishii et al.Dwarf Napier grass (Pennisetum purpureum) pasture is suitable for beef cow grazing in warm regions of Japan, while it is not assessed for the suitability by a herd of dairy cows in the region. This study was conducted to determine the effects of Digested Effluent (DE) application on herbage yield and quality, Herbage Consumption (HC) and Dry Matter Intake (DMI) … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 21 May 2016 · 8,853 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCompare Between Two-Unit Cold Standby and Warm Standby Outdoor Electric Power Systems in Changing WeatherG. S. Mokaddis, M. Salah EL-Sherbeny, Entesar Al-EsayehProblem statement: This study presents the reliability analysis of two mathematical models representing electric power systems operating in fluctuating outdoor weather (i.e., normal and stormy weather) and compared between two models. Approach: Model I deals the reliability analysis of a single-server two-unit cold standby, Model II deals the reliability analysis of a single-server two-unit warm standby, for two systems with … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,439 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStochastic Behavior of a Two-Unit Warm Standby System with Two Types of Repairmen and Patience TimeG. S. Mokaddis, M. Salah EL-Sherbeny, Y. Mahmoud AyidProblem statement: In this study we investigated the probabilistic analysis of a two-unit warm standby system with constant failure rate and two types of repairmen and patience time. The first repairman, usually called regular repairman, always remained with the repair facility, with the known fact that he might not be able to do some complex repairs within some tolerable (patience) … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,751 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReliability Equivalence Factors of a Parallel System Subject to Weibull Distribution Using Multivariate FGM CopulaNeama Salah Youssef TemrazThis paper analyze a parallel system consisted of n dependent components with lifetimes follow Weibull distribution. FGM Copula in multivariate case is used to generate the reliability function of the original system. Reduction method is introduced to improve system reliability. Other methods of hot, cold and warm duplication are established to improve system reliability. An application using real time data … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 3 Feb 2018 · 7,940 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of organic wax on bitumen characteristicsArafat Suleiman Yero, Mohd Rosli HaininStatement problem: The study investigated effect of organic wax Sasobit wax (S) on the characteristics of bitumen 80/100-penetration grade. The consistency of bitumen is measure of its susceptibility to temperature change and resistance to flow which affects ability and resistance to deformation of the mixture. Approach: This study reviewed the bitumen modification process in relation to Warm Mix Asphalt (WMA) … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Volumetric Water Footprint with Carcass and Meat Quality Characteristics Under Intensive Beef Cattle Production in South AfricaTinny Noluthando Macamba, Takalani Judas Mpofu, Khathutshelo Agree Nephawe et al.As water accessibility becomes more challenging due to the increasing human population and agricultural competition, it is crucial to select beef cattle with optimal water efficiency. The study aimed to investigate the relationship between volumetric water footprint with carcass and meat quality of beef cattle under an intensive production system. Thirty-three (33) beef cattle weaners of three different body frame … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 12 Oct 2024 · 4,728 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening of Dominant Cellulose-Degrading Microbe in Humus and Optimisation of its Enzyme Producing Conditions and Application Optimization of Enzyme Production Conditions and Evaluation of Efficient Straw Degradation by Penicillium oxalicumGailing Wang, Chendi Li, Yanan Guo et al.The slow degradation of returned straw adversely affects seedling survival rate. To shorten the degradation time of lignin in maize straw in warm temperate regions, a cellulolytic microbial strain that can secrete polymer with high enzymatic activity was isolated from the humus, which helped to identify an effective strain to expedite the decomposition of returned maize straw.
