Research ArticleOpen accessIn the abstractSeismic Response Evaluation of Moment Resistant Frame with Built-Up Column SectionMohammad Ebrahimi, Hesam Sharifian, Mohammad AhangarProblem statement: Moment Resisting Frame (MRF) is widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Response of these structures is strictly dependent upon behavior of their joints, whereas the analysis of steel moment resisting frames generally has been performed without considering the accurate connection behavior. Approach: In this study Finite Element (FE) models … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Pattern of Local Community-Based Management for Sustainable Rural Development in West Azarbaijan ProvinceLoghman Rashidpour, Seyed Jamal Farajallah Hosseini, Mohammad Chizari, Seyed Mahdi MirdamadiProblem Statement: Community-based management as incorporates both a top-down and bottom-up approach that involvement beneficiary sections such as local community, government states and non governmental organizations. It has also been applied to designate approaches where local communities play a central but not exclusive role in rural sustainable development process management. Approach: This study was survey method and is descriptive-correlation research, … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicroanatomy and Histochemistry of the Salt Glands of the Kentish Plover, Charadrius alexandrines (Aves, Charadriidae)Bashir M. JarrarProblem statement: Histological and histochemical investigations on the salt glands of birds are very limited. The present study was performed to characterize the microanatomy and histochemistry of the salt glands of the Kentish plover (Charadrius alexandrines). Approach: Salt glands of the bird under study were fixed, dehydrated, cleared, impregnated and blocked out by paraffin wax. Paraffin sections were utilized in … …OnLine Journal of Biological Sciences, Vol. 9, Issue 3 · 30 Sep 2009 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth of Bone Marrow Derived Osteoblast-Like Cells into Coral Implant Scaffold: Preliminary Study on Malaysian CoralK. A. AL-SalihiProblem statement: Biomaterial fabrication in Malaysia started as a consequence of the demand for cheaper implant materials. Various biomaterials have been developed utilizing local resources like Malaysian coral. Locally processed Malaysian coral need to be complemented with proper evaluation and testing including toxicology, biocompatibility, mechanical properties, physicochemical characterization and in vivo testing. The present study was carried out to assess … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 6,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Reliability and Productivity of an Aluminum Extruder by Implementation of Direct Torque Control TechnologyMazouz A. SalahatProblem statement: The linear motor drive is widely used in driving an extrusion puller in an aluminum extrusion industry. The main disadvantage of this drive is manual and step-wise torque control. This research was done to replace the linear motor drive by AC drive with direct torque control technology. Approach: Mathematical calculations were carried to select an AC drive which … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,267 accessesView PDFCite

Approach: The objective of this study were: (i) to … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Torsion on Externally Prestressed Segmental Concrete Bridge with Shear KeyM. A. Algorafi, A. A.A. Ali, M. S. Jaafar et al.Externally Prestressed Segmental (EPS) concrete box sections are widely used in the construction of bridge structures today. EPS concept has become an attractive tool for rehabilitation and strengthening of existing bridges which have insufficient strength and/or excessive deflection and cracking. Problem statement: EPS bridges are affected by combined stresses (bending, shear, normal, and torsional) at the joint interface between the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,428 accessesView PDFCite
