Research ArticleOpen accessIn the abstractAnalgesic and Antioxidant Activity of the Hydromethanolic Extract of Mikania scandens (L.) Willd. LeavesS.M. Raquibul Hasan, Mariam Jamila, Muntasir Mamun Majumder et al.Problem statement: Mikania scandens (L.) Willd., a medicinal plant, is popularly used as herbal remedy for various ailments in Bangladesh. But the scientific basis for its medicinal use especially in pain and inflammation remains unknown. Therefore, the present study was designed to evaluate analgesic and antioxidant potential of the hydromethanol extract of the leaves of the plant. Approach: The analgesic … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 1 · 31 Mar 2009 · 12,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractActive Fire Monitoring with Level 1.5 MSG Satellite ImagesAbdelatif Hassini, Farid Benabdelouahed, Noureddine Benabadji, Ahmed Hafid BelbachirThe first of the new generation of Meteosat satellites, known as Meteosat Second Generation (MSG-1), was launched in August 2002. As with the current Meteosat series, MSG is spin-stabilized and capable of greatly enhanced Earth observations. The satellite’s 12-channel imager, known formally as the Spinning Enhanced Visible and Infrared Imager (SEVIRI), observes the full disk of the Earth with an … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractMajor Challenges of Iranian Rural Communities for Achieving Sustainable DevelopmentKhalil Kalantari, Hossein Shabanali Fami, Ali Asadi et al.Problem statement: Rural population in Iran live in an unstable environment and geographically, villages are extremely diverse and more than 65% of them have population less than 250 persons, which do not provide sufficient population threshold for most of services and sustainable economic and job creation activities. Only 7.5% of rural areas have population more than 1000 persons. Therefore, the … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectromagnetic Assessment on Human Safety of Mobile Communication Base Stations at University of MacauK.H. Chiang, K.W. TamAssessment of the electromagnetic exposure due to the mobile communication base station at University of Macau is presented by two testing scenarios. The first scenario about 20 in-situ measurements and the maximum E-field strength was 2.46 V/m that well below the threshold and compliant to the safety guideline. The second scenario investigates on the distance effect of exposure due to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 6,752 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Assignment Procedure based on Categories' BoundariesGeorge Rigopoulos, John Psarras, Dimitrios Th. AskounisWe presented a procedure for multicriteria assignment problems. Assignment to a category is based on the comparison between an action and categories’s boundaries. Boundary is represented by the least typical action that can be included in the category, and is considered as the category’s inclusion threshold. Comparison is executed considering performance on evaluation criteria and calculation of a fuzzy inclusion … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractFollowing the Heart: The History of the J-Curve in Stroke RiskShoshana Reshef, Daniel ReshefReports of a J-shaped relationship between blood pressure and ischemic stroke are rare. The purpose of this study was to trace the published history of the J-curve theory as it relates to blood pressure, ischemic heart disease and eventually ischemic stroke. The J-curve publications on the relationship between Diastolic Blood Pressure (DBP) and ischemic stroke suggest that in certain populations, … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,356 accessesView PDFCite
Research ArticleOpen accessIn the abstractRedox Sensing and Cardiac Myocyte Loss: Some Recent InsightsShyamal K. GoswamiGeneration of reactive oxygen-nitrogen species (ROS/RNS) has long been ascribed to pathophysiological conditions like ageing, neurodegenerative and cardiovascular disorders. However, more recent evidences suggest that while generation of ROS/RNS at a higher threshold is deleterious, at a lower dose these can act as second messengers, influencing specific cellular events like cell growth and differentiation, embryonic development, protection against ischemic injuries … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractExact Permutation Algorithm for Paired Observations: The Challenge of R. A. FisherJ. I. Odiase, S. M. OgbonmwanThe major handicap of permutation test is the logical and computational requirement necessary to develop and implement the exact permutation scheme. This study provides an algorithm that systematically enumerates all the distinct permutations of the paired observations in an experiment without the possibility of repeating any of the permutations. The permutation algorithm presented completely breaks down the permutation problem for … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Probability Density Function of the Test Statistic for One Nonlinear GLR Detector Arising from fMRIFangyuan NanRecently an important and interesting nonlinear generalized likelihood ratio (GLR) detector emerged in functional magnetic resonance imaging (fMRI) data processing. However, the study of that detector is incomplete: the probability density function (pdf) of the test statistic was draw from numerical simulations without much theoretical support and is therefore, not firmly grounded. This correspondence presents more accurate (asymptotic) closed form … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 7,106 accessesView PDFCite
