Research ArticleOpen accessIn the abstractToward Clean Green Sustainable Development to Prevent the First Food World War, Changing Authoritative-Public Extension to Literalized-Partnership Extension SystemIraj MalakmohammadiProblem statement: The main purpose in this study is to provide a more rational platform in extension modeling to respond to the very recent world-wide warnings calling up for global revision of the present extension practices to put the appropriate science and technology to application to securing Clean-Green Sustainable Development (CGSD). Approach: To achieve this purpose, extension education was reconsidered … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,050 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Blood Turbulent Flow in Carotid Artery Including the Effects of Mural Thrombosis Using Finite Element ModelingM. Arab-Ghanbari, M. M. Khani, A. Arefmanesh, F. Tabatabai-GhomsheArterial thrombosis is an extremely significant health problem. As a result of numerous factors involved in such problem, describing the role of hemodynamics in thrombogenesis has been asserted to be one of the most demanding and complicated challenges in biomechanics. An axisymmetric model considering fluid-structure interactions (FSI) was introduced and numerically solved for an artery with a thrombosis to perform … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractAAV-Based Targeting Gene TherapyWenfang Shi, Mingxia Yu, Qijun QianSince the first parvovirus serotype AAV2 was isolated from human and used as a vector for gene therapy application, there have been significant progresses in AAV vector development. AAV vectors have been extensively investigated in gene therapy for a broad application. AAV vectors have been considered as the first choice of vector due to efficient infectivity, stable expression and nonpathogenicity. … …American Journal of Immunology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,964 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biostabilization of Old MSW LandfillsM.C. ZanettiMany years after the end of the cultivation phase, landfills may generate intense odours, toxic and explosive gases and heavily-polluted leachate. A wide-spreading trend in the management of MSW landfills is represented by the forced aeration of wastes in order to achieve the stabilization, reducing the negative environmental impact of uncontrolled sites (old landfills which can be definitely considered as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransforming Spatio-Temporal Yield Maps to Classified Management Zone Maps for Efficient Management of Oil PalmAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm plantations today is proper interpretation of yield maps for site-specific management and development of classified management zone maps for its efficient management. A study was conducted on an on-going fertilizer response trial in Sabah, Malaysia to examine the possibility of converting spatio-temporal yield maps of oil palm to classified management zone maps … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Temporal Yield Trend of Oil Palm as Influenced by Nitrogen Fertilizer ManagementAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm (Elaeis guineensis Jacq.) plantations today is proper interpretation of yield maps for site-specific management and identification and understanding of the causal factors influencing the variability of oil palm yields. A study was conducted to examine the structural yield variation in order to assess the spatial and temporal yield trends so as to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistological Features and ki-67 Index In Cervical Atypical LesionsD. Cabibi, L. Giovannelli, M. Cacciatore et al.One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 7,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating E-learning Programs: An Adaptation of Kirkpatrick's Model to Accommodate E-learning EnvironmentsThair M. HamtiniProblem Statement: Kirkpatrick's model for the evaluation of training programs has been a staple in institutional learning since 1959 and is easily applicable to any training program. Approach: This model, however, was developed for traditional learning environments and has been regarded as antiquated, especially when one took into consideration the fact that institutional learning has increasingly taken on the form … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 7,959 accessesView PDFCite
