Research ArticleOpen accessIn the abstractRed-Cell Trace Minerals in Children with AutismJoan Jory, Woody R. McGinnisAbnormalities in mineral-dependent antioxidant enzymes in children with autism raise interest in the determination of trace mineral status in this population. A cross sectional investigation of red cell mineral levels was carried out among 20 children with autism and 15 controls. Children with autism demonstrated significantly lower red cell selenium (p<0.0006) and higher molybdenum (p<0.01) than the controls. There was … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,877 accessesView PDFCite
Research ArticleOpen accessIn the abstractSugarcane Phenological Date Estimation Using Broad-Band Digital CamerasMobasheri, M. Chahardoli, J. Jokar, M. FarajzadehIn the agricultural industry, precision farming is the most important task that attracts lots of attentions. The health of the plant depends mostly on the amount of water in its access that can be estimated through vegetation indices. These indices can be extracted from satellite images through Image processing algorithms. The objective of this research was to provide an equation … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 7,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectronic Energies in Delta Doped AlGaAs/GaAs HeterostucturesA. Meftah, H. Ajlani, A. Marzouki et al.The band bending of the potential at the AlGaAs/GaAs interface increases with the electrons concentration in the GaAs channel. This band bending is often ignored in the theoretical calculation of the electronic energies and a linear potential approximation was used. This led to imprecise energy values and occupied subband configurations. We have taken account of the band bending in the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractECG Signal Denoising By Wavelet Transform ThresholdingMikhled Alfaouri, Khaled DaqrouqIn recent years, ECG signal plays an important role in the primary diagnosis, prognosis and survival analysis of heart diseases. In this paper a new approach based on the threshold value of ECG signal determination is proposed using Wavelet Transform coefficients. Electrocardiography has had a profound influence on the practice of medicine. The electrocardiogram signal contains an important amount of … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 16,512 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength and Ductility of Randomly Distributed Palm Fibers Reinforced Silty-Sand SoilsS.M. Marandi, M.H. Bagheripour, R. Rahgozar, H. ZareThis paper investigates the resultant strength and ductility behavior when randomly distributed palm fibers are used to reinforce silty-sand soils. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS), California Bearing Ratio (CBR) and compaction test. The results indicated that; the maximum and residual strengths, orientation of surface failures, ductility and the stress-strain relationship … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolitical Stability and Economic Growth in AsiaMuhammad Younis, Xu Xiao Lin, Yahya Sharahili, Santhirasegaram SelvarathinamThis study investigates the effects of various factors of political instability on economic growth in selected ten Asian economies during 1990-2005. Our empirical findings show a close relationship between political stability and economic growth. We have analyzed the data by using ordinary least squire econometrics methods, which conclude that 32.35 scores increasing of index of political stability leads to one … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,559 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Indoor Positioning System (IPS) using Grid ModelWutjanun Muttitanon, Nitin Kumar Tripathi, Marc SourisTo date many positioning systems are available to determine or track a user's location; three main categories include Global Positioning System (GPS), wide area location system and indoor positioning system. GPS has its limitation (poor signals) in indoor or urban uses, while wide-area location systems are cellular networks dependent. For indoor positioning system many approaches like infrared sensing, radio frequency, … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractSociopolitical Instability and Economic Growth Empirical Evidence from Sri LankaChangsheng Xu, Santhirasegaram Selvarathinam, Wen Xing LiSociopolitical instability severely affects economic growth in short and long run. This study analyzes that sociopolitical instability measured by proxy measure; annual growth rate of tourist arrivals in Sri Lanka during 1960-2005 adversely affects economic growth. Our empirical findings based on ordinary lease square econometric estimation, show that sociopolitical instability negatively and significantly affect economic growth. Reduction of economic growth … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Modeling of a New Tactile Sensor Based on Membrane DeflectionAli Tavakoli Golpaygani, Siamak Najarian, Goldis Darb EmamiehThe designed sensor can detect 2D surface texture image, contact-force, and softness of the sensed object. It consists of a chamber for pneumatic actuation and a membrane with a mesa structure. The sensing mechanism is the contact deformation effect of a membrane. Determination of the contact force and softness of sensed object is based on the amount and variations of … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,789 accessesView PDFCite
