Research ArticleOpen accessIn the abstractWhat Accounts for Growth in African AgricultureGuy B. Nkamleu, Kalilou Sylla, Abdoulaye ZononEmpirical relationships between the rates of growth and total factor productivity growth, physical input accumulation, as well as institutional and agro-ecological change is evaluated using an international panel data set on 26 African countries and covering the period 1970-2000. The analysis employs the broader framework provided by empirical growth literature and recent developments in TFP measurement. Results suggest a positive … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractSociopolitical Instability and Capital Accumulation in Developing Countries: Cross Country pooled data EvidenceAbdul Haque, Selvarathinam Santhirasegaram, Muhammad YounisThis study shows that sociopolitical conflicts measured by peace building capacity in developing countries affect physical and human capital accumulation in selected 70 developing countries from all regions of the world during 2000-2004 by using econometric models. We conclude that sociopolitical instability negatively and significantly effect both physical and human capital accumulation in selected countries. Sociopolitical stability in developing countries … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,871 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determinants of Urban Household Poverty in MalaysiaT. Y. Mok, C. Gan, A. SanyalSince independence in 1950s Malaysia has been recognized as one of the more successful countries in fighting poverty: head count ratio came down to 5.7% by 2004. However the recent process of rapid urbanization has led to an increase of urban poverty aggravated further by the 1997 Asian financial crisis. It is important to understand the nature and scale of … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 9,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Treatment of the Mathematical Models for Water PollutionF. B. Agusto, O. M. BamigbolaTo evaluate the environmental impact of pollution, mathematical models play a major role in predicting the pollution level in the regions under consideration. This paper examines the various mathematical models involving water pollutant. We also give the implicit central difference scheme in space, and a forward difference method in time for the evaluation of the generalized transport equation. …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunohistochemistry Assay to Detect Turkey Coronavirus (TCoV) from Experimentally Infected PoultsThais Larissa L Castanheira, Heitor F. Ferrari, Maria Cecília R. Luvizotto, Tereza C. CardosoThe objective of this study was to develop a direct immunohistochemical assay to detect TCoV antigens in formalin-fixed paraffin-embedded sections prepared from experimentally infected poults. The sections of ileo, ileo-cecal junction and ceca regions from intestine were prepared and submitted to two different primary antibodies, first the non-biotin labeled polyclonal antibody for the indirect method, and second the biotin-labeled polyclonal … …American Journal of Immunology, Vol. 3, Issue 2 · 31 Dec 2007 · 6,900 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of 2D Multi Electrodes Resistivity Imagining for Sinkholes Hazard Assessment along the Eastern Part of the Dead Sea, JordanAbdallah S. Al-Zoubi, Abd El-Rahman A. Abueladas, Rami I. Al-Rzouq et al.Sinkholes and subsidence are natural phenomena can be occurred in shallow geology sediments at different regions in the world. Sinkholes assessment is one of the most difficult near subsurface investigations. Geophysical prospecting is appropriate method to determine environmental and geotechnical problems. 2D multi electrodes resistivity imagining with Wenner-Schulmberge array was conducted within active sinkholes area. The objective of the survey … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Axisymmetric Thermal Plume between Vertical PlatesJamil Zinoubi, Adel Gammoudi, Taoufik Naffouti et al.This investigation analyses the turbulent structure of a thermal plume created by a heated disk, evolving between vertical plates. The objective of the study was to understand the development mechanisms of this buoyancy driven flow. The analysis of the average and the fluctuating fields of the temperature as well as the flow visualisation show the existence of three different zones. … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractClassification of Squamous Cell Carcinoma Based On Color and Textural Features in Microscopic Images of Esophagus TissuesP. S. Hiremath, Y. Humnabad Iranna, Jagadeesh D. PujariThis paper presents a method for feature extraction using color and texture from microscopic images of esophagus tissues obtained from the abnormal regions of human esophagus detected through endoscopy. This method is used for classification of Squamous Cell Carcinoma (SCC) of esophagus, namely, poorly differentiated SCC, moderately differentiated SCC, and well differentiated SCC. Three different color spaces, namely, HSV, YCbCr, … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of a Putative Functional Region in the Human Bax Protein by Computational AnalysisMaría Sánchez-Aguilar, Laurence A. Marchat, Absalom ZamoranoStructural domains are relevant elements for interactions between Bcl-2 family members to regulate apoptosis and cell survival. Although BH1-BH4 domains can be identified by their sequence and selective occurrence in Bcl-2-family members, structural regions have not been entirely determined yet. The functional residues of Bax, the most representative pro-apoptotic protein of the human Bcl-2 family, remain almost unknown. Here, we … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Pathology of Alzheimer Disease Elicits an In Vivo Immunological ResponseDavid J. Bonda, Kate M. Webber, Sandra L. Siedlak et al.The mechanism(s) responsible for the loss of neurons that characterizes Alzheimer disease is incompletely understood. Nonetheless, there is considerable evidence suggestive of immune abnormalities coupled to alterations in blood-brain barrier permeability that likely play a key role in both the etiology and progression of the disease. To examine these issues further, this study was designed to examine the presence of … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 7,115 accessesView PDFCite
