Research ArticleOpen accessIn the abstractTrace Metals Co-Toxicity in Hard Body Structures of Liza klunzingeri (Mugilidae: Perciformes) Mullet FishA.H. Bu-Olayan, B.V. Thomas, S.M.H. Al-HusainiThe possibility of inorganic pollutants causing stress to the marine ecosystem instigated us to conduct eco-toxicological tests on the predominant trace metals (Cu, Zn, Pb and V) in commercial important fish. Among the four metals, V had the lowest observed effect concentration (LOEC: LC15) at 6.3 µg L-1. Toxicity tests (96 h) using Multi factor Probit analysis revealed V (6.3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Charaterization of Magnesium Zinc Ferrites as Electromagnetic SourceNoorhana Yahya, Ami Salwani Mohamad Nor Aripin, Azizuddin A. Aziz et al.Fabrication of Mg1-XZnXFe2O4 (where x = 0.2, 0.3, 0.4 and 0.5) samples using a conventional technique is reported. Oxides of magnesium, zinc and iron with purity of about 99.99% were mixed with distilled water in a milling machine for 12 hours. They were then filtered and presintered at 1250°C and sintered at 1350°C for 10 h in air. The phase … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 9,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolymer in Agriculture: a ReviewFrancesco Puoci, Francesca Iemma, Umile Gianfranco Spizzirri et al.In agricultural field, polymers are widely used for many applications. Although they were used, in the first time, just as structural materials (inhert polymers), in the last decades functionalized polymers revolutionized the agricultural and food industry with new tools for several applications. Smart polymeric materials and smart delivery systems helped the agricultural industry to combat viruses and other crop pathogens, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 21,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrimary Pollutants Monitoring and Modeling Using Chemical Mass Balance (CMB) Around Fahaheel Residential AreaS. M. Al-Salem, A. A. Al-Haddad, A. R. KhanFour major sources of air pollution were identified and modeled using Chemical Mass Balance (CMB) around a residential area. The sources were identified as MAA refinery, downtown area, upstream facilities and main highway road. The sources were analyzed using a series of concentration roses (unfiltered and filtered) executed from the data collected. Data collected included primary and secondary pollutants levels … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractMiniature-Autopilot Evaluation SystemKamal Ali, Lamarious CarterThis research describes a Hardware in the Loop Simulator (HILS) that was developed to enhance the quality of attitude data received from autopilots. The described system aided in adjusting the contribution of individual IMU sensors and thereby improved the accuracy of IMU data. The HILS system outlined in this research is a gimbaled platform equipped with four stepper motors and … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasures on the Quotient Spaces of the IntegersNorris Sookoo, Peter ChamiSK-partitions were introduced by Sharma and Kaushik, who defined distances (metrics) between vectors in terms of partitions of the alphabet set Fq , the set of the ring of integers modulo q. These distances were applied in Coding Theory. The research examined algebraic and topological aspects of SK-partitions and related sets of measures. A lattice of SK-partitions was introduced and … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,014 accessesView PDFCite
Research ArticleOpen accessIn the abstractAmbient Levels of Primary and Secondary Pollutants in a Residential Area: Population Risk and Hazard Index Calculation over a Three Years Study PeriodS. Al-Salem, A. Al-FadhleeThis paper aims at presenting data collected over the period of three years (2004-2006) in a residential area in the state of Kuwait. The data collected include ambient levels of primary and secondary pollutants with a number of metrological parameters. A series of unfiltered and filtered concentration roses were plotted to determine the predominant sources as well as the prevailing … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Packet Marketing Method in DDoS Attack DetectionChanghyun Beak, Junaid Ahsenali Chaudhry, Keonsoo Lee et al.Functionality and availability are one of the main characteristics of internet and hence very inviting for attackers to try to provoke a denial-of-service attack. As the intensity and frequency of DDoS attacks has increased, various preventive mechanisms have also been proposed. One of the most effective defence mechanisms proposed was Path Identification (Pi). This method tracks the packet transmission path. … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Main Object-oriented Projective Invariant Image Watermarking ApproachMalik F. AlamairehDigital Watermarking is a technology that enables to protect distributed digital content from unauthorized reuse. Robust watermarks must be able to survive a range of geometrical "attacks," such as image resizing, cropping, translation, rotation, scaling, smoothing, filtering, and simplification. In the current paper we extend existing approaches that are based partially on image invariant features; by introducing new image invariant … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomedicine and Informatics Model of Alzheimer's DiseaseKang Cheng, Chang-Hua ZouIn a perspective of biomedicine and informatics, the mechanism of Alzheimer's, senile amnesia, or other aging-associated and cognitive impairment related diseases involve four important informative processing procedures: propagation, consolidation, retrieval and cognition, In this study, we systematically model the four procedures based on published experimental data. When modeling the propagation, we develop an equivalent circuit of biological membrane to describe … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 28 May 2007 · 6,828 accessesView PDFCite
