Research ArticleOpen accessIn the abstractAN OPTIMIZATION-BASED HEURISTIC FOR A CAPACITATED LOT-SIZING MODEL IN AN AUTOMATED TELLER MACHINES NETWORKSupatchaya Chotayakul, Peerayuth Charnsetthikul, Juta Pichitlamken, John KobzaThis research studies a cash inventory problem in an ATM Network to satisfy customer’s cash needs over multiple periods with deterministic demand. The objective is to determine the amount of money to place in Automated Teller Machines (ATMs) and cash centers for each period over a given time horizon. The algorithms are designed as a multi-echelon inventory problem with single-item … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 1 Oct 2013 · 7,049 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTREND ANALYSIS OF MONTHLY RAINFALL DATA IN CENTRAL ZONETelemu KassileProper trend analysis of rainfall data is necessary for social and economic planning especially in the tropics where rainfall is a major limiting factor for crop production. In spite of the growing number of studies on climatic variables including rainfall in recent years, in the context of Tanzania little is known as to whether or not the observed time trend … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 15 Mar 2013 · 7,939 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal Population Dynamics of the Asian Citrus Psyllid, Diaphorina citri Kuwayama in SarawakStephen Leong Chan Teck, Abang Fatimah, Andrew Beattie et al.Problem statement: Effective control of phytophagous pests requires a thorough understanding of their seasonal population dynamics, dispersion behavior, natural enemy activity and climate. To date, although very little detail information had been published on the ecology of Diaphorina citri. The objective of this investigation was to test through field experiment the hypothesis that the major factors influencing local D. citri … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 27 Dec 2011 · 9,551 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDietary Lysine: Calorie Ratios and Their Influence on Nitrogen Metabolism and Digestibility in Moderately Obese Mature DogsTrista Reeder, Greg Hibbard, Kyle R. McLeod, David L. HarmonProblem statement: A goal during weight loss is to reduce body fat while maintaining body protein. We hypothesized that an increased dietary lysine: calorie might be beneficial during periods of caloric restriction. Approach: Two experiments were conducted to determine if changing the ratio of lysine: calories (lysine g/kg: Mcal ME/kg) while maintaining an ideal profile of amino acids will change … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 27 Apr 2011 · 8,064 accessesView PDF Cite

Research ArticleOpen accessIn the abstractForecasting Daily Demand in Cash Supply ChainsMichael WagnerProblem statement: Previous studies focused on explaining the long run determinants of currency demand offering limited insight into the short-run determinants and co-variability of daily demand in cash supply chains. Approach: This study contrasted competing techniques of forecasting daily demand in cash supply chains in order to determine the overall performance and the potential of joint forecasting for integrated planning. … …American Journal of Economics and Business Administration, Vol. 2, Issue 4 · 28 Nov 2010 · 7,736 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEconomic Sanctions, Oil Price Fluctuations and Employment: New Empirical Evidence from LibyaAbdusalam Faraj Yahia, Ali Salman SalehThis research attempts to examine the links between fluctuating oil prices, economic sanctions and the employment in the Libyan economy. In particular, this study attempts to answer the basic question whether UN’s resolutions number 748 (1992) of 31 March 1992 and oil price fluctuations have any significant influence on the employment in Libya. One of this study’s key findings is … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,438 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Comparative Study between Various Protocols of MANET NetworksMohammed F. Al-Hunaity, Salam A. Najim, Ibrahiem M. El-EmaryMulticast Ad-Hoc on-Demand Distance Vector (MAODV) protocol keeps sending control packets within static periods whether there was sending of data packets or not, and it was not concerned with the amount of these data packets. Based on this, many people found out that there are a high number of control packets in the short-lived connection. The main idea of this … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,957 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Concentrations of Glucose can Activate or Inhibit Human Erythrocyte Aminolevulinate Dehydratase in vitro Depending Exposure TimeJ. C. Soares, D. Gabriel, V. Folmer et al.Hyperglycemia can cause oxidative stress and inactivate susceptible enzymes. In the present investigation we examined whether short-term incubations (24 or 48 h) with high concentrations of glucose (10-200 mmol L-1) inhibit ALA-D from human erythrocytes. Incubations of erythrocytes for 24 h with glucose (10 up to 40 mmol L-1) resulted in an increase of δ-ALA-D activity (P<0,001). Incubations of erythrocytes … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 6,686 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDissecting Two Approaches to Energy PricesJulius N. Esunge, Andrew Snyder-BeattieProblem statement: This research tested the viability of Geometric Brownian Motion as a stochastic model of oil prices. Approach: Using autoregressions and unit root tests, we determined that oil prices tend not to exhibit the Markov Property and thus GBM may be a problematic model. Results: Instead, oil prices seem to be mean reverting over the long run, possibly following … …Journal of Mathematics and Statistics, Vol. 7, Issue 2 · 18 May 2011 · 7,100 accessesView PDF Cite
