Research ArticleOpen accessEvery word in the titleVariable Separation and Boubaker Polynomial Expansion Scheme for Solving the Neutron Transport EquationDada O.M., O.B. Awojoyogbe, M. Agida, K. BoubakerProblem statement: In this study, we present general analytical solutions to the Neutron Boltzmann Transport Equation NBTE using a polynomial expansion scheme. Approach: Some simple assumptions have been introduced in the main system thanks to the Boubaker Polynomial Expansion Scheme (BPES) in order to make the general analytical procedure simple and adaptable for solving similar real life problems. Results: Finding … …Physics International, Vol. 2, Issue 1 · 21 Jan 2012 · 7,595 accessesView PDFCite
Research ArticleOpen accessIn the keywordsConceptual Archaeology of a Temporal Place: Albert and Kessler (1976) Applied to Chacma Baboons (Papio ursinus)Lucy Baehren, Susana CarvalhoAlthough leave-taking in non-human species has been preliminarily investigated in a few species, the mechanisms driving encounter ends remain unstudied. In 1976 Albert and Kessler published a landmark paper, outlining theories about what drives social encounter ends and providing a framework of internal and external motivations leading to separation. This framework has been underused in aiding our understanding of how … …Journal of Social Sciences, Vol. 20, Issue 1 · 21 Mar 2024 · 6,227 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFrequency, Substance and Procedural Shortcomings of State Level Impeachment Campaigns in an Emerging Federal DemocracyIbraheem Oladipo MuheebNigeria’s 1999 Constitution encompasses separation of powers and checks and balances. It enjoins institutional autonomy in specific spheres, and systemic mutual inter-dependence of the legislature, executive and judiciary. The legislature has unfettered right to be self-regulatory including intra-institutional changes in leadership. Such right must be exercised responsibly and in conformity with the Constitution. Erring executive official could be impeached by … …Journal of Social Sciences, Vol. 12, Issue 2 · 17 Jun 2016 · 8,461 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPurification of Natural Gas with Impurities using Membrane Processes: Parameter EstimationN. W. Jusoh, K. K. Lau, A. M. ShariffProblem statement: Membrane processes have received a significantly high attention on natural gas separation processes since this technology provides higher operating and cost advantages as compared to other technologies. One of the major problems related to natural gas separation using membrane is the existence of feed impurities including CO2, heavy hydrocarbon and water. Approach: Hence, mathematical model that is able … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 22 May 2012 · 8,426 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetection of Listeria monocytogenes in Ready-to-Eat Meat ProductsAsma M.M.A. Abdelgadir, Kunwar K. Srivastava, P. Gopal ReddyProblem statement: The objective of this study was to develop a rapid and sensitive method for the detection of Listeria monocytogenes and to screen large number of ready-to-eat (RTE) meat samples. Approach: A total of 250 fresh RTE meat samples of different varieties (chicken, turkey, beef, pork and cold cuts) were purchased from local grocery stores. Results: From the 250 … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 30 Jan 2012 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecurity Extensible Access Control Markup Language Policy Integration Based on Role-Based Access Control Model in Healthcare Collaborative EnvironmentsTeo Poh Kuang, Hamidah Ibrahim, Nur Izura Udzir, Fatimah SidiRecently research is focused on security policy integration and conflict reconciliation among various healthcare organizations. Problem statement: However, challenging security and privacy risk issues still arisen during sharing sensitive patient data in different large distributed organizations. Though eXtensible Access Control Markup Language (XACML) has a powerful capacity of expression, it does not support all the elements character of RBAC. Thus, … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 26 Jan 2011 · 9,067 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExistence and Uniqueness Conditions for the Maximum Likelihood Solution In Regression Models For Correlated Bernoulli Random VariablesDavid Todem, KyungMann KimWe give sufficient and necessary conditions for the existence of the maximum likelihood estimate in a class of multivariate regression models for correlated Bernoulli random variables. The models use the concept of threshold crossing technique of an underlying multivariate latent variable with univariate components formulated as a linear regression model. However, in place of their Gaussian assumptions, any specified distribution … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation and Beneficiation of Feldspar from Arkosic Sandstone in South Jordan for Application in the Ceramic IndustryMousa GougazehThe main purpose of the present study was to investigate the beneficiation and upgrading processes of a Jordanian feldspar ores to be finally implemented in the ceramic industry. The experimental work was conducted to evaluate the role of particle size distribution, chemical composition, mineral content and the magnetic impurities (Fe2O3 +TiO2 contents). The beneficiation of the 500-45 μm fractions, which … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,981 accessesView PDFCite

Research ArticleOpen accessIn the keywordsCharacterization of Household Wastes in D.R. Congo, a Case Study of LubumbashiMartin T. Mpinda, Sissou Zakari, Olusegun K. Abass et al.The insufficient supervision of household solid waste is a notorious problem in DR. Congo cities. Besides, solid waste management in Lubumbashi has been very rudimentary and unsystematic. This study aims to quantify and characterize the household solid waste in two Lubumbashi municipalities. For more than 50 years after independence from colonialism, the city trailed direct discharge of waste on exposed … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 10 Jun 2017 · 8,217 accessesView PDFCite
