Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF COTTONWalter B. Gordon, Larry Murphy, Pawel WiatrakCrop recovery of applied Phosphorus (P) fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca), Magnesium (Mg), iron (Fe) and Aluminum (Al) to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP), … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 10 May 2014 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Aluminium Chloride on Anxiety-Related BehaviourA.A. Buraimoh, S.A. Ojo, J.O. Hambolu, S.S. AdebisiProblem statement: Aluminium is presents in many manufactured foods, medicines and is also added to drinking water for purification purposes. It has the potential to be neurotoxic in human and animals but its contribution in Alzhemer’s disease remains contradictory. Anxiety affects one-eighth of the total population world-wide and has become an important area of research interest in psychopharmacology. Approach: The … …Neuroscience International, Vol. 2, Issue 2 · 27 Feb 2012 · 7,972 accessesView PDFCite
Research ArticleOpen accessIn the abstractFPGA-Based Architecture for a Generalized Parallel 2-D MRI Filtering AlgorithmSami Hasan, Said Boussakta, Alex YakovlevProblem statement: Current Neuroimaging developments, in biological research and diagnostics, demand an edge-defined and noise-free MRI scans. Thus, this study presents a generalized parallel 2-D MRI filtering algorithm with their FPGA-based implementation in a single unified architecture. The parallel 2-D MRI filtering algorithms are Edge, Sobel X, Sobel Y, Sobel X-Y, Blur, Smooth, Sharpen, Gaussian and Beta (HYB). Then, the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 20 Feb 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Endometrial Thickness on Intracytoplasmic Sperm InjectionMohammed Al-SunaidiProblem statement: Endometrial receptivity is a key factor in successful outcome of in vitro fertilization. The endometrial receptivity is determined clinically by estimation of endometrial thickness and pattern by ultrasonography. This study was performed to evaluate the overall effect of endometrial thickness on pregnancy rate, multiple pregnancy rate and miscarriage rate in infertile women undergoing Intracytoplasmic Sperm Injection (ICSI) cycles … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 13 Feb 2012 · 7,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of A Microwave Amplifier for Wireless ApplicationM. Habib Ullah, Badariah Bais, Norbahiah Misran et al.Problem statement: Low-Noise Amplifiers (LNA) are very indispensable components in the design of numerous types of communication receivers employed in microwave technology. This paper is presents the design and development of low bias(Vce = 8v, Ic =10 mA) single stage low noise microwave amplifier operating in 1.5GHZ frequency range, Gain 13dB ± 0.5dB, input/output return loss < -10dB, noise figure … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 8,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructure of Lamellae and Chloride Cell in the Gill of Alosa Caspio Caspio (Clupeidae, Teleostei)Z. Saadatfar, D. ShahsavaniAs a surface for respiratory gas diffusion, ion regulation and waste excretion, gill epithelium of Alosa Caspio Caspio has been investigated. Problem statement: Surely, morphological study of gill cells is the main route for giving the basic data which can be inductive for physiological and pathological investigations. Approach: Gills were removed from Alosa Caspio which is from euryhaline species and … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Heat Flow in Computational Method and Its Verification on the Structure and Property of Gray Cast IronS. K. Shaha, M. M. HaqueProblem statement: The solidification of materials depends on the cooling rate of the materials which is governed by heat flow in the mould and alloy composition. Solidification rate also affects the structure and properties of the materials. Approach: In the present study, the heat flow of cold set resin bonded sand mould was simulated using JL Analyzer FEM analysis software. … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,355 accessesView PDFCite
