Purpose: Modeling the characteristics of personality and motivation of medical student's development following the establishment of an appropriate methodology to act in university physical education lessons by developing and implementing a strategic program included in organization, management and conduct training process-education, the means of … …Journal of Social Sciences, Vol. 7, Issue 4 · 10 Aug 2011 · 8,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Prototype Two-Axis Laser Scanning System used in Stereolithography Apparatus with New Algorithms for Computerized Model SlicingM. Habibi, H. Shahmohammadi, V. Taraghi et al.Problem statement: A successful operation of rapid prototyping process depends on software and hardware which are used in RP machines. About software, an efficient technique is required to slice the CAD model. Several slicing methods are used for slicing from Standard Triangulation Language (STL) files, such as direct slicing and adaptive slicing. Using these methods reduce accuracy of physical part … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractRegional Development Model for East AzerbaijanHamid R. AlipourProblem statement: Economic development is a process through which scientific-technical production principles change from a traditional status to a modern one. Development is an important event that not only encompasses the government duties, but alters the regional statesmen to be active elements in the development as well. Along the same lines, the present economic trends around the world tend to … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical Properties Analysis of Frictional Winding Mechanism with Bobbin Elastic SupportMohammed A. Alnawafleh, Faisal M. Al-GhathianA mathematical model of the Frictional Winding Mechanism (FWM) with bobbin elastic supports for a search of optimal structural and physical parameters for developing new and updating existing FWMs has been carried out. The model was derived from bobbin equipped with pendulum suspension for forming cylinder shaped packages. In the derivation method it was considered that the model corresponds the … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue Green-alga Spirulina sp. Part II. Mathematical ModelingKatarzyna Chojnacka, Piotr M. WojciechowskiIn the present paper bioaccumulation of Cr(III) ions by blue-green algae Spirulina sp. is discussed. We found that the process consisted of two stages: passive in which Cr(III) ions are bound to the surface of cells, identical with biosorption and active, metabolism-dependent, in which Cr(III) ions are transported into the cellular interior. The passive stage occurs in both living and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF REACTION TEMPERATURE AND REACTION TIME ON PRODUCT FROM HYDROTHERMAL TREATMENT OF BIOMASS RESIDUEJakaphong Kongpanya, Kanokorn Hussaro, Sombat TeekasapThailand is facing with problems associated with biomass residue such as palm oil residues (oil palm trunks, oil palm fronds, empty fruit bunches, shells and fibers). Biomass is promising source for the production of an array of energy-related produts including, liquid, solid and gaseous fuels, heat, chemicals electricity and other materials. Therefore, the use of biomass for energy is not … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 2 Jun 2014 · 7,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractEXERCISE TRAINING REVERSES THE DELETERIOUS EFFECT OF SUCROSE INTAKE ON INSULIN RESISTANCE AND VISCERAL FAT MASS DEPOSITION ON MICEJulio Cesar Mendes Soares, Vanderlei Folmer, Gustavo Puntel, João B.T. Da RochaAbnormal fat deposition has been identified as an important mechanism of obesity-associated with insulin resistance. Literature data also indicate that exercise can improve insulin action. The heme pathway enzyme δ-Aminolevulinate Dehydratase (δ-ALA-D) is a good marker for oxidative stress and this sulfhydryl enzyme is inhibited in such oxidative pathologies diabetes. The aim of this study was to evaluate the effects … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 28 Mar 2014 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractACCELERATION AND PARTICLE FIELD INTERACTIONS OF COSMIC RAYS II: CALCULATIONSA. Tawfik, A. Saleh, M.T. Ghoneim et al.The Ultra High Energy Cosmic Rays (UHECRs) is still a one of the most controversial physical problems, especially that all potential acceleration mechanisms are not entirely able to explain the source of UHECR and their energy scale. Based on our generic acceleration model, that suggests different types of electromagnetic interactions between the cosmic charged particles and the different configurations of … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 7,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Interventions in AgingSuresh I.S. RattanSingle or multiple exposure to low doses of potentially harmful agents can have a variety of anti-aging and longevity-extending hormetic effects. These hormetic stressors include irradiation, physical activity, food limitation, heat, hypergravity, dietary components and reactive oxygen species. Molecular mechanisms facilitating the hormetic effects are being elucidated and comprise a cascade of stress response and maintenance and repair pathways. Although … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractMRI Observation and Analysis of Muscle Activity During ExerciseLi-Chang Zou, Hong-Wu LiWhile conventional biomechanical testing techniques are able to determine the mechanical characteristics of muscle tissue, they do not offer precise insight into how muscle metabolism and microstructure change in response to various types of exercise activities over the course of time. Using Magnetic Resonance Imaging (MRI) analysis of muscle tissue allows researchers to examine how different levels of intensity affect … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 30 Jul 2026 · 1,035 accessesView PDFCite
