Research ArticleOpen accessIn the author namesUsing Look-up Tables to Model an Electromagnetic Suspension SystemMusaab HassanProblem statement: The aim of the study was to model an electromagnetic suspension system. The electromagnetic system consists of an electromagnet which was attracted an iron object which was freely suspended in air. Approach: Modelling a magnetic system requires modelling the magnetic force characteristics and the flux characteristics. The force characteristics were to be produced from a nonlinear flux characteristic-current. … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 21 Jun 2012 · 6,889 accessesView PDFCite
Research ArticleOpen accessIn the author namesVoice-Based Control of a DC Servo MotorHammam Mahjoub, Musaab Hassan, Mohammed ObedProblem statement: Motors play a very important role in our life and among which is the DC servo motors. The techniques of controlling these DC motors are plenty, among which is sound. In this study, a voce-based technique was implemented to control the speed and the direction of rotation for a DC motor. Approach: A Microcontroller-based electronic control circuit was … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 4 Jun 2012 · 9,099 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetermination of Lead in Soil along the Highways of KosovaAlbert Maxhuni, Fatmir Faiku, Musaj Pacarizi et al.Problem statement: During recent several decades soil was polluted more and more serious by heavy metals because of mining, smelting, irrigating with sewerage and some other human activities. These heavy metals may adversely affect soil ecology, agricultural production or product quality and ground water quality and will ultimately harm to health of mankind by food chain. Approach: We had analyzed … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 6 Jan 2012 · 7,077 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnticancer Activities of Some New Synthesized Thiazolo[3,2-a]Pyrido[4,3-d]Pyrimidine DerivativesAshraf M. Mohamed, Abdel-Galil E. Amr, Musaed A. Alsharari et al.Problem statement: This study describes the synthesis and anticancer activities of a new series of thiazolo[3,2-a]pyrimidines derivatives (2-7) using 3,5-bisarylmethylene-1-methyl-4- piperidone and 4-aryl-8-arylmethelene-6-methylpyrido[4,3-d]pyrimidine-2(1H)thiones as a starting materials. Approach: The antitumor activities of the newly synthesized compounds 4-7 were evaluated utilizing 60 different human tumor cell lines, representing leukemia, melanoma, lung, colon, brain, ovary, breast and prostate as well as kidney. … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 23 Aug 2011 · 10,087 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 accessesView PDFCite
Research ArticleOpen accessIn the author namesUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Use of Neural Network to Recognize the Parts of the Computer MotherboardAbbas M. Ali, S. D. Gore, Musaab AL-SarierahThis study suggests a new approach of learning which utilizes the techniques of computer vision to recognize the parts inside the motherboard. The main thrust is to identify different parts of the motherboard using a Hopfield Neural Network. The outcome of the net is compared with the objects stored in the database. The proposed scheme is implemented using bottom -up … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,865 accessesView PDFCite
