However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractPresence of Arsenic in Commercial BeveragesJason Roberge, Andrew T. Abalos, Julia M. Skinner et al.Problem statement: This study’s goal was to assess the arsenic concentration of various beverages and broths purchased from a local chain supermarket. A source of chronic arsenic exposure occurs via food and beverage consumption. Groundwater levels of total arsenic are regulated (<10 μg L-1) by the Environmental Protection Agency (EPA) but few studies have examined arsenic concentrations in common beverages. … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,348 accessesView PDFCite

Research ArticleOpen accessIn the abstractConstrained Single Period Stochastic Uniform Inventory Model With Continuous Distributions of Demand and Varying Holding CostHala A. Fergany, M. E. El-SaadaniThis paper derives the single period stochastic inventory model with continuous distributions of demand and the holding unit cost is a function of the purchased (ordered) quantity. The objective is to find the optimal purchased quantity which minimizes the expected total cost for the period under a restriction on the expected varying holding cost when the demand during the period … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractImperfectly-Rational Agents, Volatility of Reserves and Customer MarketsPartha Gangopadhyay, Renu GangopadhyayPotential customers in customer markets are typically dichotomised into actual and prospective customers.
