Research ArticleOpen accessIn the abstractA Design Strategy for Volumetric Efficiency Improvement in a Multi-cylinder Stationary Diesel Engine and its Validity under Transient Engine OperationP. Seenikannan, V.M. Periasamy, P. NagarajThis paper proposes an approach to improve engine performance of volumetric efficiency of a multi cylinder diesel engine. A computer simulation model is used to compare volumetric efficiency with instantaneous values. A baseline engine model is first correlated with measured volumetric efficiency data to establish confidence in the engine model's predictions. A derivative of the baseline model with exhaust manifold, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Short or Long Term FGA Treatment with or without eCG on Reproductive Performance of Ewes Bred Out-of-seasonMustafa Q. Husein, Mohammed M. Ababneh, Dia S. Abu-RumanThe objective was to evaluate the effects of intravaginal FGA sponges inserted for 4 or 12 days with or without eCG on reproductive performance of ewes out-of-season. Forty-eight anestrous ewes were assigned in equal numbers to four treatments in a 2x2 factorial design. Ewes were administered with FGA sponges on May 17 for 12 days (12-day-FGA-eCG and 12-day-FGA groups, n= … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,492 accessesView PDFCite
Research ArticleOpen accessIn the abstractPeriodicity of the HIV/AIDS Epidemic in a Mathematical Model that Incorporates ComplacencyFlugentius Baryarama, Livingstone S. Luboobi, Joseph Y.T. MugishaAn HIV/AIDS model incorporating complacency for the adult population is formulated. Complacency is assumed a function of the number of AIDS cases in a community with an inverse relation. A method to find the equilibrium state of the model is given by proving a stated theorem. An example to illustrate the application of the theorem is also given. Model analysis … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOn a Novel Closed-Form Analytical Solution for Unsteady Solidification: Theory and ApplicationGueber Elias Mendes Santos Júnior, Fernando S. Rocha, Ana Beatriz S. Silva et al.Numerical modeling of transient solidification under convective boundary conditions presents a significant challenge because accurately tracking the solid–liquid interface is essential for obtaining a stable solution. Although analytical solutions are generally straightforward to apply, the growing demand for energy storage driven by mismatches between supply and demand in renewable‑energy systems requires reliable predictive tools for Latent Heat Thermal Energy Storage … …American Journal of Engineering and Applied Sciences, Vol. 19, Issue 1 · 21 May 2026 · 1,680 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplication of Moving Bed Biofilm Process for Biological Organics and Nutrients Removal from Municipal WastewaterM. Kermani, B. Bina, H. Movahedian et al.In this study, experiments have been conducted to evaluate the organics and nutrients removal from synthetic wastewater by a laboratory scale moving bed biofilm process. For nutrients removal, moving bed biofilm process has been applied in series with anaerobic, anoxic and aerobic units in four separate reactors. Moving bed biofilm reactors were operated continuously at different loading rates of nitrogen … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,097 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordApplication and Prospect of CO2 Enrichment Technology in AgricultureBingbing Wang, Xiangjie Lu, Wanlin Gao et al.With the increasing consumption of fossil fuels for human activities, the emissions of greenhouse gases, such as CO2, have significantly increased, resulting in an intensified greenhouse effect. As an important element for plant photosynthesis, CO2 enrichment in an appropriate environment can promote photosynthetic rate, organic matter accumulation and the growth rate of plants. The CO2 enrichment technology should be widely … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 10 Feb 2022 · 6,457 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling Tourist Arrivals in Destination Countries: An Application to Australian TourismS. A.H. Shobeiri Nejad, Gurudeo Anand TularamProblem statement: Little study is evident of mathematical modeling regarding tourist arrivals in South East Queensland of Australia. In this study the Bulter conceptual destination life cycle and product life cycle frameworks are used to develop an overall determinant mathematical model of Australian tourist arrivals. The model will be calibrated using real Australian data. A more complex dynamic is also … …Journal of Mathematics and Statistics, Vol. 6, Issue 4 · 31 Dec 2010 · 7,920 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordScreening 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. Using the molecular … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 23 May 2023 · 5,303 accessesView PDFCite
