Research ArticleOpen accessIn the abstractRainfall Variation and Changing Pattern of Agricultural CycleMd. Mahmudul Alam, Mohd Ekhwan bin Toriman, Chamhuri Siwar, Basri TalibProblem statement: The decision of crop selection and the output of agricultural production are highly determined by the environmental factors, especially rainfall and water availability. In the tropical area, particularly in Malaysia, influences of these exogenous variables are so high that overall agricultural productions are now vulnerable. Crops are affected through rainfall in two different ways-high and low rainfalls. Avoiding … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 9,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Fish Farming on Household Income: A Case Study from Mymensingh DistrictSyed Mohammad Aminur Rahman, Ariful Haque, Syed Md. Ashrafur RahmanProblem statement: Fisheries sector is a rising sector in Bangladesh. Many farmers are shifting their rice fields to ponds for fish farming in the study areas. This transformation of farming raises a question to the researchers whether fish farming has any impact on household income or not. Thus, the researchers took the present study to identify the contribution of fish … …Journal of Social Sciences, Vol. 7, Issue 2 · 2 Feb 2011 · 8,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractShear Strength of Reinforced Concrete Beam Strengthened by Transverse External Post-tensionSayan Sirimontree, Boonsap Witchayangkoon, Nathavudh Khaosri, Jaruek TeerawongProblem statement: Shear failure of concrete beam is brittle manner without warning so inadequate design for shear of beam and/or material deterioration lead to the possibility of sudden failure of beam. The change of functional use and future increased load of structure lead to the need for strengthening of concrete structure. Approach: This research focuses on behaviors under static loading … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,869 accessesView PDFCite
Research ArticleOpen accessIn the abstractElastic-Plastic Non Linear Behaviors of Suddenly Loaded StructuresAssal Tehseen HusseinProblem statement: The adaptively shifted integration technique was applied to the elasticplastic analysis of framed structures under dynamic loading. Approach: This study used analysis of linear beam element, the reshifting of the of the integration points in the element is conducted in order to attain higher accuracy. Results: In nonlinear finite element analysis by the ASI technique, the highest computational … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 8,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Iron Deficiency among Human Immunodeficiency Virus Sero PositivesM. A. Pradeep, M. Thiruvalluvan, K. Aarthy, J. M. MaryProblem statement: Iron is an important dietary mineral and involves in various body functions. In humans, iron is an essential component of proteins involved in oxygen transport. It is also essential for the regulation of cell growth and differentiation. Iron and its binding protein have immune regulatory properties and shifting of immune regulatory balances by iron excess or deficiency may … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 7,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Modernity on Kurdish Architectural IdentitySalahaddin Yasin Baper, Ahmad Sanusi HassanProblem statement: This study discussed the concept of identity and the role of modernity in shifting towards globalization. The literature study covered definitions of the key words which are modernity, identity and architecture. The definition included description and issues related to the key words, which became a crucial study in identifying factors which influence the concept of change and continuity … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 10,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of 1H NMR Spectra of 2,3-Dihydro-4-Pyridinones Derived from BisdemethoxycurcuminWisam A. Radhi, Bahjat A. SaeedProblem statement: The studied dihydropyridones were synthesized via microwave assisted reaction of bisdemethoxycurcumin and amines or amine acetates which is new approach in the synthesis of this important class of compounds and the deep study of their NMR spectra seems reasonable. Approach: 1H NMR spectra of dihydropyridones derived from curcumin were discussed and their structures were elucidated accordingly. Results: The … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,264 accessesView PDFCite

Better understanding of microencapsulation process is useful to properly design of microcapsule with specific characteristics. The aim of this research is to study the mechanism of Urea-Formaldehyde (UF) microcapsules formation. Approach: Microcapsule was prepared in two steps. The first step was the preparation of oil … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,718 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnisotropy Influence of Cubic Solid on Dynamic Hertzian Contact Stiffness for a Vibrating Rigid IndenterJiayong TianProblem statement: Resonance-type microscopies have been widely used to evaluate the nanoscaled or microscaled surface elastic properties of materials by the resonance-frequency shifts of an oscillator, which contacts the surface of materials by a spherical tip. Approach: The tip-specimen contact is modeled to be a spring support, whose stiffness is given by the traditional Hertzian contact theory. However, because of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,715 accessesView PDFCite
