Research ArticleOpen accessIn the abstractGreen Building Construction Thermal Isolation Materials (Rockwool)Mahmoud ItewiProblem statement: Building insulation consisting roughly to anything in a structure that is utilizes as insulation for any reason. Thermal insulation in structures is a significant feature to attaining thermal comfort for its tenants. Approach: Insulation decreases unnecessary warmth loss or gain and can reduce the power burdens of heating and cooling structures. It does not automatically having anything to … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 9,426 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Markov Chains to Stock TrendsKevin J. Doubleday, Julius N. EsungeProblem statement: Modeling of the Dow Jones Industrial Average is frequently attempted in order to determine trading strategies with maximum payoff. Changes in the DJIA are important since movements may affect both individuals and corporations profoundly. Previous work showed that modeling a market as a random walk was valid and that a market may be viewed as having the Markov … …Journal of Mathematics and Statistics, Vol. 7, Issue 2 · 18 May 2011 · 8,564 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplications of Conditional Value at Risk to Full Truckload Pricing Under Demand and Service Time UncertaintiesThitima Wonginta, Sompong SirisoponsilpProblem statement: Pricing is one of the fundamental management decisions required by a truckload carrier. Traditional pricing based on an average all relevant costs including fixed and variable costs is not capable of providing adequate margins that prevent losses during operation uncertainties inherent in truckload operation including demand variability and variation in service times. Approach: This study utilizes Conditional Value … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 8,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractReflectivity of Reflectarrays Based on Dielectric SubstratesM. Y. Ismail, M. Inam, A. M.A. ZaidiProblem statement: Reflectarrays provide a low cost and low profile solution for antennas required for high gain applications but their use is restricted in some applications due to the narrow bandwidth and high loss performance. These performance limitations can be attributed to different sources of reflectivity of the reflectarrays. This work provides a thorough investigation on the reflectivity performance of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Protein and Lysine on Performance and Carcass Yield of TurkeysF. Peñaranda-Ali, R. Santos-Ricalde, L. Sarmiento-Franco et al.Problem statement: There is a concern related to loss of nitrogen to the environment from animal manure and the high cost of the protein supplement. Thus, the current study was undertaken to determine the effect of reduction of CP and increased of lysine on growth and carcass yield in turkeys. Approach: A factorial experiment was carried out with commercial turkeys … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Bacillus subtilis 'PB6' (ATCC - PTA 6737) on Clostridium difficile Associated Diarrhea (CDAD) and Inflammatory Bowel Disease (IBD) in Animal ModelsEric Peys, Jerry Varghese, Ponusami Suresh et al.The administration of probiotic bacteria is emerging as a potential means of preventing the onset or recurrence of Clostridium difficile associated diarrhea (CDAD) and of attenuating inflammatory activity and preventing relapses in inflammatory bowel disease (IBD). We evaluated the efficacy of Bacillus subtilis 'PB6' (ATCC - PTA 6737) in a hamster model of antibiotic-induced CDAD and in a rat model … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractRedox Sensing and Cardiac Myocyte Loss: Some Recent InsightsShyamal K. GoswamiGeneration of reactive oxygen-nitrogen species (ROS/RNS) has long been ascribed to pathophysiological conditions like ageing, neurodegenerative and cardiovascular disorders. However, more recent evidences suggest that while generation of ROS/RNS at a higher threshold is deleterious, at a lower dose these can act as second messengers, influencing specific cellular events like cell growth and differentiation, embryonic development, protection against ischemic injuries … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractExergoeconomic Analysis of a Refrigeration CycleDurriye Bilge, Galip TemirThe exergoeconomic theory is applied to a two stage vapour compression refrigeration cycle. An exergy-aided cost analysis, taking into account pressure drops and heat gain/loss for all of the components in the refrigeration system as well as the pipe connections, has been made. Exergoeconomic factors, showing whether the monetary expenditures mostly originate from capital investment and Operating and Maintenance (O&M) … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,149 accessesView PDFCite
Review ArticleOpen accessIn the abstractManaging Internal Parasites of Small Ruminants using Medicinal Plants a Review on Alternative Remedies, Efficacy Evaluation Techniques and Conservational StrategiesWandile Nikelo, Maliviwe Mpayipheli, Lyndy McGawThroughout the world, internal parasites are a majorhindrance to small ruminant production. The most common internal parasites ingrazing small ruminants are likely to be gastrointestinal nematodes. They causea reduction in live-weight gain, wool growth, poor reproductive performance,and increased production costs and thus hamper global food security.Pharmaceutical control continues to be the main measure used to manage orcontrol internal parasites, however … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 4 · 6 Oct 2022 · 6,849 accessesView PDFCite
EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,503 accessesView PDFCite
