Research ArticleOpen accessIn the keywordsSpherical and Improved Helmholtz Coil with High B1 Homogeneity for Magnetic Resonance ImagingSidi M. Ahmed Ghaly, Khalid A. Al-Snaie, Obaidullah Khan MohammadSeveral types of volume RF coils such as Helmholtz pair have been used for Magnetic Resonance Imaging. However, the field uniformity of a coil has always been suffering from a critical issue in imaging accuracy. The presented work is a study and design of spherical and improved radiofrequency Helmholtz coil which produces a high B1 magnetic field homogeneity. This coil … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 8,159 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtein Secondary Structure Prediction using Hybrid Recurrent Neural NetworksRomana Rahman Ema, Akhi Khatun, Md. Alam Hossain et al.The most important and challenging problem in bioinformatics is protein secondary structure prediction. The molecules of all protein organisms have three-dimensional (primary, secondary, 3-D) structures which are completely recognized by the sequence of amino acids. Protein secondary structure attributes to the polypeptide backbone of the local configuration of proteins. Most generally, the second-level prediction is indicated such as: If there … …Journal of Computer Science, Vol. 18, Issue 7 · 14 Jul 2022 · 7,332 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn silico Analysis of three Committed-Steps Involved in Triterpenoid Biosynthesis from Ganoderma lucidumXiaorong Shui, Xiaozhong Lan, Wei LeiGanoderma lucidum is widely considered as one of the most valuable Traditional Chinese Medicines, with various bioactive constituents and pharmaceutical effects. Triterpenoids are important effective ingredients of G. lucidum, which are synthesized mainly through the mevalonate pathway. In this study, we aimed to characterize and analyze three committed-step enzymes of the mevalonate pathway, 3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase (HMGR), Farnesyl Diphosphate Synthase … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 15 Aug 2016 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Silico Characterization and Motif Election of Neurotoxins from Snake VenomMahmudul Hasan, Ziaul Faruque Joy, Elius Hossain Bhuiyan, Md Shiful IslamSnake venom is a mixture of many biological components. Snakes usually use their venomic armory to tackle different prey and predators in adverse natural world. Among various components of the snake venom, neurotoxins play an important role in exerting effect by blocking the neuromuscular transmission through selective binding to muscle nicotinic Acetyl-Choline Receptors (nAChR). A set of 30 reference protein … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 2 Mar 2015 · 7,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractA HIGH B1 FIELD HOMOGENEITY GENERATION USING FREE ELEMENT ELLIPTICAL FOUR-COIL SYSTEMSidi M. Ahmed Ghaly, Sulaiman S. Al-SowayanDesign and testing of a prototype probe with high B1 magnetic field homogeneity that can be used for MRI is presented. It consists of four coaxial separately tuned rings of wire in a symmetric arrangement on an ellipsoidal surface. Compared to Helmholtz pair, which presents 2nd-order homogeneity, an improvement in field homogeneity is achieved, while preserving the simplicity of implementation. … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 28 Jan 2014 · 7,019 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE DETECTION OF OPEN AND SHORT FAULT IN SWITCHED RELUCTANCE MOTOR WITH CLASSIFICATIONV. S. Chandrika, A. Ebenezer JeyakumarSwitched reluctance motors are tremendously increasing in usage. Monitoring the motor performance online is essential, in order to maintain the health of the motor as well as for a continual application process carried out by the SRM. Though certain fault detection methods are available based on comparator circuits, those methods are inefficient, because they need human attention to identify the … …Journal of Computer Science, Vol. 10, Issue 5 · 23 Jan 2014 · 6,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Tactile Force Probe for Tissue Stiffness ClassificationBehafarid Darvish, Siamak Najarian, Elham Shirzad, Roozbeh KhodambashiIn this study, we have proposed a new type of tactile sensor that is capable of detecting the stiffness of soft objects. The sensor consists of a brass cylinder with an axial bore. An iron core can easily move inside the bore. Three peripheral bobbins were machined in the cylinder around which three coils have been wound. One of the … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,286 accessesView PDFCite
