Research ArticleOpen accessIn the abstract"Green Economy" as the Country's Development Strategy with a High Share of the Commodity Sector in the Context of GlobalizationAskarova Maulken, Medeu Alikhan, Medeu AkhmetkalThe "Green economy" is a economy, aimed at preserving a well-being of society through the effective use of natural resources and ensuring return of end-use products in the production cycle. First of all, the "green" economy focused on economic use of the resources that are currently subject to depletion (natural resources-oil, gas) and the rational use of inexhaustible resources. The … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,305 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKey-Hole Notches in Isostatic Graphite: A Review of Some Recent DataA. Gagani, Relly Victoria V. Petrescu, Florian Ion T. PetrescuFracture of the breakable isostatic graphite is concerned using the experimental and theoretically, the plates containing nicks holes key subject to varying degrees of mixed task. The main purpose of this work is a double one. In the first place, in order to offer a new set of experimental results on fracture of samples of graphite scored, with different values … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,012 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimal Ordering Policy with Stock-Dependent Demand Rate Under Retailer’s Two Stages Trade Credit Financing Using Discounted Cash Flow (DCF) ApproachRakesh Prakash Tripathi, Harendra Singh, Neha SangMany researchers have assumed one stage trade credit financing. In this study, we considered two levels of trade credit policy using Discounted Cash Flow (DCF) approach. Demand rate is considered to be stock-dependent for the first level (credit demand) and constant for second level (cash demand). Mathematical models are derived under two different circumstances i.e., case I: The permissible delay … …Journal of Mathematics and Statistics, Vol. 11, Issue 3 · 18 Nov 2015 · 7,080 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHippocampal Pyramidal Cell Degeneration and Changes in Creb Protein in Datura stramonium Treated RatsPeter Etim Ekanem, Dare S. Sunday, Sunday Abba, Amanuel TesfayDatura Stramonium (DS) is a tropical shrub which is available worldwide. It has various uses and is often used to increase the intoxication of certain beverages. The seeds of this plant are very toxic but are commonly smoked in like manner as tobacco. The present study investigated the potential harmful effects of DS on pyramidal cells and CREB protein in … …Neuroscience International, Vol. 6, Issue 2 · 17 Sep 2015 · 7,062 accessesView PDF Cite

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 · 10,414 accessesView PDF Cite

Case ReportOpen accessIn the abstractSocial Psychology and Performative Interventions in Human Systems. The GENERATIVE MethodAlessio Nencini, Alessandro Meneghini, Marco PratiThe purpose of this paper is to describe the GENERATIVE method, a methodology for promoting change in human systems (i.e., contexts involving human interactions, such as organizations, communities, institutions). The first part of the paper is focused on the description of the interactionist and constructionist epistemological background adopted. The second is dedicated to the presentation of human systems as socially … …Journal of Social Sciences, Vol. 11, Issue 1 · 29 May 2015 · 7,416 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Non-Linear Absolutely-Stable Explicit Numerical Integration Algorithm for Stiff Initial-Value ProblemsEssam R. El-ZaharThe time-step in integration process has two restrictions. The first one is the time step restriction due to accuracy requirement τac and the second one is the time-step restriction due to stability requirement τst. The most of explicit methods have small stability regions and consequently small τst. It obliges us to solve stiff problems with small step size τst << … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 11 Sep 2013 · 7,559 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Parametric Optimization of an Organic Rankine Cycle Powered by Solar EnergyFrancesco Calise, Claudio Capuozzo, Laura VanoliThis study presents the simulation and performance analysis of a regenerative and superheated Organic Rankine Cycle (ORC). To this scope, anew simulation model has been developed. The model is based on zero-dimensional energy and mass balances for all the components of the system. Shell and tube heat expanders with single shell and double tube pass have been chosen. Pump and … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 15 May 2013 · 7,684 accessesView PDF Cite
