Research ArticleOpen accessEvery word in the titleAn NPV Optimization Model for Closed-Loop Supply Chain Network Design and PlanningAl-Ashhab Mohamed Sayed, Nahid AfiaAs the importance of forward-reverse logistics increases, attention will be focused on parameters which affect Net Present Value (NPV) of the whole system, aiming at considering the time value of money in planning. In this research, an NPV optimization model for multi-period multi-product closed-loop supply chain network design and planning is developed to maximize the total NPV. The effect of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 18 Feb 2017 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIs Wright Test an Appropriate Screening Test for Diagnosis of Brucellosis?Behzad Mohsenpour, Shahla Afrasiabian, Katayoon Hajibagheri, Ebrahim GhaderiProblem statement: Diagnosis of brucellosis is generally based on culture, polymerase chain reaction and serology. The first two methods are not accessible in all parts of world and are expensive. The routine method for diagnosis of brucellosis is considering Wright test as the first screening test; if the results are Wright positive’ Wright would be the next choice otherwise 2ME … …American Journal of Infectious Diseases, Vol. 7, Issue 2 · 17 Sep 2011 · 16,762 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstablishing an Adaptive Production-Procurement System with Markov Chain Approach Associated with 3C TheoryChun-Ta LinProblem statement: In this study, we classify the imperfect situations that the unreliability of production and the defective products might be incurred from production process into eight independently recurrent categories. Approach: With the property of recurrence of Markov chain, the limiting probability of each imperfect production category can be calculated through the transition probabilities matrix generated from these imperfect production … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Evaluation of Standalone Hybrid PV–H2 with Storage SystemAdeyinka Victor Adebayo, Samuel Oladeji, Hussein Kehinde Adebayo, Ismaheel Oyeyemi OladejoThis study evaluates the economic performance of a standalone hybrid PV-H2 system with battery storage for small-scale electricity demand. The methodology involves comparing various configurations of standalone PV, storage, and hybrid PV-H2 systems under different discount rates and evaluation periods. Economic indicators such as Net Present Value (NPV), Payback Period, and Discounted Annualized Return (AAR) determine financial viability. Results indicate … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 4 Mar 2025 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Subsurface Appraisal: A Key Link to the Success of Development Projects-Few ExamplesVirendra Singh, Ivan Yemez, Elena Izaguirre, Alvaro RaceroDuring exploration and production phases, the life of a hydrocarbon field can be distinguished by five main stages: Exploration, appraisal, development, production and abandonment. Of particular interest is the appraisal stage, where billions of dollars are spent across the oil and gas industry on data gathering activities with a view to reducing subsurface uncertainties towards optimizing reservoir development and management. … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 13 Jan 2017 · 8,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Efficiency Analysis for Information Technology in Developing CountriesGhassan F. Issa, Shakir M. Hussain, Hussein Al-BahadiliProblem statement: The introduction of Information Technology (IT) to government institutions in developing countries bears a great deal of risk of failure. The lack of qualified personnel, lack of financial support and the lack of planning and proper justification are just few of the causes of projects failure. Study presented in this study focused on the justification issue of IT … …Journal of Computer Science, Vol. 5, Issue 10 · 30 Oct 2009 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Serological Gastric Biopsy: A Non-endoscopical/Histopathologic Diagnostic Approach in Management of the Dyspeptic PatientsR. A.K. Mahmoud, H. H. Morcos, A. A. Hegazi et al.Objective: To asses the sensitivity, specificity and the predictive value of a 'gastropanel' blood test, including serum pepsinogen I (S-PGI) and amidated gastrin-17 (S-G-17) in the diagnosis of atrophic gastritis most probably due to helicobacter pylori (Hp) and to compare the results of serology with the endoscopic/histopathologic findings as a gold standard diagnostic tool. This study comprised 86 dyspeptic outpatients … …American Journal of Immunology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractPush-pull Strategy with Trap Crops, Neem and Nuclear Polyhedrosis Virus for Insecticide Resistance Management in Helicoverpa armigera (Hubner) in CottonP. Duraimurugan, A. RegupathyInsecticide resistance in Helicoverpa armigera (Hubner) is a major threat to cotton production in India. The virus infection was found to increase the susceptibility of H. armigera to the insecticides. But, use of Nuclear Polyhedrosis Virus (NPV) on a larger scale and on cotton due to leaf alkalinity poses certain practical problems. Hence, studies were carried out to assess the … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 9,098 accessesView PDFCite
