Research ArticleOpen accessIn the abstractA Greater dose of Ractopamine Hydrochloride Enhances Feedlot Performance and Impacts Carcass Characteristics of Calf-Fed Holstein SteersJerilyn E. Hergenreder, Jonathon L. Beckett, Zachary K. Smith, Bradley J. JohnsonThe objective was to evaluate the effects of supplementing ractopamine HCl at the rate of 400 mg steer1 daily in the final 28 d of the feeding period on growth performance and carcass characteristics of Holstein steers. Steers (n = 1,498; initial BW = 547 kg) were randomly assigned to pens (10 pens/treatment) and to a treatment: (1) 0 mg∙steer1∙d1 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 24 Mar 2021 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrologic Modeling to Evaluate the Impact of Hydraulic Fracturing on Stream Low Flows: Challenges and Opportunities for a Simulation StudySuresh Sharma, Aashish Shrestha, Colleen E. McLean, Scott C. MartinHydraulic fracturing (fracking) has been increasing in the eastern part of Ohio for the last few years leading to the increased stress on water resources, particularly on the hydrological low flows. Yet, evaluation of the various impacts of fracking on stream low flows using appropriate tools is still a challenging issue, even though significant progress has been achieved in recent … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 7 Aug 2015 · 10,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractENERGY EFFICIENT NETWORK SELECTION USING 802.16G BASED GSM TECHNOLOGYH. Anandakumar, K. UmamaheswariHandover is the mechanism that transfers information from one terminal to another as a user moves through the coverage area of a cellular system. Here the Network selection is the handover decision process between various network environments. This handover decision will be either mobile or network initiated. In 2G GSM handover decision method especially concentrates on Received frequency signals (RFS). … …Journal of Computer Science, Vol. 10, Issue 5 · 31 Dec 2013 · 7,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Vitamin A on Growth Performance, Antioxidant Status and Blood Constituents in Lactating Grey GoatWeiren Yang, Ping Wang, Yuanqiang Jing et al.Problem statement: It is regarded that vitamin A protects cells from damage by radicals which are believed to contribute to certain chronic diseases and regulates immune function of animals by protection of mucosal epithelium acting as the first defense barrier. All these properties of vitamin A may be attributable to its antioxidant activity. This study was to evaluate the effects … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 7,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency Estimation of Innovative Activity the EnterprisesAndrey Sergeevich Nechaev, Dmitry Alekseevich Antipin, Oksana Victorovna AntipinaThe widely acknowledged fact is that the economic growth based only on an export of the raw materials cannot be stable for a long time and thereupon the financial support of an innovative activity gets of a special urgency. To provide higher and steady rates of an economy growth it is necessary to carry out a transition to an innovative … …Journal of Mathematics and Statistics, Vol. 10, Issue 4 · 5 Jan 2015 · 7,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Prickly Poppy Methyl Ester Blends on Ci Engine Performance and Emission CharacteristicsP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: The aim of this research was to investigate the effect of using Prickly poppy methyl ester as a fuel blend on Diesel engine (CI engine) performance and exhaust emission. Approach: Short-term engine performance tests were conducted to evaluate and compare the use of various diesel fuel supplements at blend rations of 60/40, 70/30, 80/20, 90/10, in a standard, … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Learning Styles on Education and the Teaching ProcessIbrahim Yasar KazuProblem statement: It is of great importance that individuals actively participate in the learning process; that, starting from the early ages, their awareness be raised about the efficiency of the learning styles in developing their academic success and self-confidence; and that the learning styles they have be determined. For this reason, this study aimed to reveal the learning styles having … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 17,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Ammonia Loss by Mixing Urea with Liquid Humic and Fulvic Acids Isolated from Tropical Peat SoilSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Fertilizer N use efficiency is reduced by ammonia volatilization. Under low soil CEC and high pH, N from soil solution is released to the atmosphere. Ammonia loss due to low worldwide N use efficiency (33%) has been implicated in global warming. Thus, the objectives of this laboratory study were to evaluate the effectiveness of liquid humic and fulvic … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractLab Tests for the Remediation of a PCE Polluted Site by Means of HRC ReactantMaria Chiara Zanetti, Silvia FioreThe injection of reactants is a remediation technology that may be applied both in the vadose zone and in groundwater.
