Research ArticleOpen accessIn the abstractSolving Protein Folding Problem using Elitism-Based Compact Genetic AlgorithmAmr Badr, Ibtehal M. Aref, Basma M. Hussien, Yosr EmanProteins are vital components of living cells. A number of diseases such as Alzheimer's, Cystic fibrosis and Mad Cow diseases are shown to result from misfunctioning of proteins. Problem statement: Protein folding problem is the process of predicting the optimal 3D molecular structure of a protein, or tertiary structure, which is an indication of its proper function. Approach: An enhancement … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractArchitecture for Combined Energy and Attitude Control SystemIbrahim Mustafa Mehedi, Renuganth Varatharajoo, Harlisya Harun, Mohd Nizam FilipskiCombining the energy and attitude control system is a feasible technology for small satellites to improve the space missions. In this Combined Energy and Attitude Control System (CEACS) a double rotating flywheel is used to replace the conventional battery for energy storage as well as to control the attitude of an earth oriented satellite. Each flywheel is to be controlled … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Lignin Fraction Extracted from Brazilian Energy CropsDiogo José Horst, Jhon Jairo Ramírez Behainne, Pedro Paulo de Andrade Junior, Luís Filippe SerpeThis study quantifies the extraction performance and some properties of the lignin obtained from six crops with potential for generating thermal energy in Brazil. A full factorial design (22) with four replicates including two extraction methods and two particles size distributions was adopted for assessing the fraction of lignin, as well as its Higher Heating Value (HHV) and composition given … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 27 Apr 2015 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanisms of Anti-Cancer Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Vernonia amygdalina (V. amygdalina) has been shown to have cancer cell inhibition and cytotoxic effects. Approach: This study discusses the multi-faceted and multi-linked mechanisms by which cancer tissue inhibition and destruction is achieved by V. amygdalina leaf extract and powder (subsequently called V. amygdalina Extract). Cancer cell inhibition by V. amygdalina is suggested to occur through inhibition of … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 26 Oct 2011 · 9,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review of Constitutive Models for Rubber-Like MaterialsAidy Ali, M. Hosseini, B. B. SahariProblem statement: This study reviewed the needs of different constitutive models for rubber like material undergone large elastic deformation. The constitutive models are widely used in Finite Element Analysis (FEA) packages for rubber components. Most of the starting point for modeling of various kinds of elastomer is a strain energy function. In order to define the hyperelastic material behavior, stress-strain … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 21,720 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Consumption and Performance’s Library on DSPs: Case Study MPEG2Jalel Ktari, Mohamed Abid, Nathalie Julien, Johann LaurentThe growing demand for portable electronic devices has led to an increased emphasis on power consumption within the semiconductor industry. As a result, designers are now encouraged to consider the impact of their decisions not only on speed and area, but also on power throughout the design space exploration. This article presents a high-level design space exploration methodology. It allows … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,828 accessesView PDFCite
Review ArticleOpen accessIn the abstractSIRT1 Controls Lipid Metabolism Under Physiological and Pathological Conditions: Implications in AtherosclerosisAnastasia Vladimirovna Poznyak, Ludmila Viktorovna Nedosugova, Victoria Alexandrovna Khotina et al.This comprehensive review examines the multifaceted role of Sirtuin 1 (SIRT1) in cellular metabolism and energy regulation, with a particular focus on its involvement in lipid metabolism and glucose regulation. Additionally, SIRT1's impact on several pathologies, including osteoarthritis, diabetes, and cardiovascular disease, is explored. Notably, this review sheds light on the unique contribution of SIRT1 in the development and progression … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 7 Jun 2024 · 4,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractA COMPARATIVE STUDY FOR RHODOPSIN PROTEIN FOLDING PROBLEMIman Ahmed Mahmoud, Amr Ahmed Badr, Mostafa Abdel AzimProteins are very important components in any living cells. A number of diseases such as Retinitis pigmentosa, Stargadt-like macular degeneration and Doyne Honeycomb Retinal Dystrophy (DHRD) diseases are shown to result from misfunctioning of proteins. Protein folding problem is a way to predict the best and optimal 3D molecular structure (tertiary structure) of a protein which is then considered to … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Housing RenewalM. Sitar, K. KrajncFollowing the already proved models the sustainable planning culture is endangering several methods directed towards the needs of tenants in the existing post-war housing stock. The case-study of our project is the renewal of the multi stored building in the housing estate Metalna, Maribor/Tezno (1949). It is based on the sustainable renovation principle for the quality of sustainable housing in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Aware Optimal Routing for Wireless Sensor NetworksS. Chandramathi, U. Anand, T. Ganesh et al.Wireless Sensor Network (WSN) is a collection of autonomous devices with computational, sensing, and wireless communication capabilities. The sensor nodes are low cost, multi-functional devices that are densely deployed either inside the phenomenon or very close to it and are often powered by independent power sources. The lifetime of such sensor nodes show a strong dependence on lifetime of the … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,649 accessesView PDFCite
