Research ArticleOpen accessIn the keywordsLocal Youth Historical Research for Students Based Learning Reform, Northeast ThailandPrasopsuk RittidetProblem statement: The research problem of education came from school teachers who emphasized high grade-point average. The immediate social, Cultural aspects were overlooked. Students were drawn to consume media, internet and individual person to a greater extent. By taking up foreign culture. The students forgot, if not, ignored their own historical root. The purpose of the study was to study … …Journal of Social Sciences, Vol. 7, Issue 2 · 9 Mar 2011 · 7,206 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvolution of a Graduate Environmental Science ProgramWill Focht, Talya HendersonProblem statement: Environmental science programs vary widely in their curricula and pedagogical approaches. In part, this is due to the lack of a unified agreement on field identity. However, program differences are also the product of variable program histories. Approach: This essay described the founding and subsequent history of the Environmental Science Graduate Program at Oklahoma State University, its oldest … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 7,010 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCase Study on the Effects of Plan Irregularities on Seismic Performance of StructuresEduardo Flores, Tadeh ZirakianGeometric configurations, such as large openings, re-entrant corners, and discontinuity in diaphragms, are very common in architectural design but are seen as undesirable for structural performance during earthquakes. The lateral systems in a structure resist the strong forces induced during an earthquake, preventing damage or collapse of the structure. If these systems fail, the structural integrity of the building may … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 21 Jul 2024 · 5,723 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Simple and Accurate Relation Between the Logarithm Integral Li(x) and the Primes Counting Function π(x) is Derived Making use of the O.E.I.S. Prime Numbers “Sequences”Paolo AscarelliToday the prime numbers π(x) contained under the number x appears to be somewhat overestimated by the logarithm integral function Li(x) and underestimated by the function x/ln(x), both originally proposed by Gauss around 1792-1796. However, a simple and accurate expression, relating Li(x) and π(x), may be derived using the data reported on the O.E.I.S. “Sequences”. This relation can also suggest … …Journal of Mathematics and Statistics, Vol. 17, Issue 1 · 30 Sep 2021 · 7,739 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFrom Hyperthermia to Immunomodulating PolysaccharidesNovak Miroslav, Vetvicka VaclavNatural polysaccharides remain overlooked as part of naturally occurring bioactive molecules. The current knowledge results in numerous clinical trials, from first observations of their effects on various diseases to precise chemical characterization and decades of biological evaluation. The aim of this report is to summarize historical perspective of the route from the first anecdotical observation to the current position, with … …American Journal of Immunology, Vol. 13, Issue 1 · 30 Mar 2017 · 7,079 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWelded Connections of Wind Turbine Towers under Fatigue Loading: Finite Element Analysis and Comparative StudyNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosIncreased contemporary energy needs have led to multiple investments on wind power plants and structural improvements are considered necessary for the construction of taller, more robust and more economical structures. Tubular steel wind turbine towers that are the prevailing structural configuration, demand welding of circular subparts to construct the tower structure. These circumferential welds between tower subparts and between the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 18 Aug 2015 · 8,894 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCRITERIA FOR THE COMPLEXITY OF SUCCESSIVE ASTRONOMICAL PARADIGMSPanagiotis Papaspirou, Kostas Karamanos, Xenophon MoussasWe investigate the complexity of three successive astronomical paradigms in the science of Physics, namely the Ptolemaic paradigm, the Copernican paradigm and the Keplerian paradigm and mention briefly some characteristic facts about the colossal Newtonian paradigm. This complexity can be understood according to five criteria, as proposed by Thomas Kuhn, the father of the epistemological notion of the paradigm, as … …Physics International, Vol. 5, Issue 1 · 28 Mar 2014 · 8,295 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPractitioner and Faculty Perspectives on the Career Preparation Of Entry-Level Public AccountantsKathryn Simms, Enrique ZapateroEntry-level public accountants in the U.S. must satisfy a litany of historically unparalleled requirements and demands. This unique set of challenges calls forth new questions about how effectively entry-level accountants are navigating the divide between their conceptual educations and the practical rigors of public practice. To examine these questions, we relied on qualitative analysis predicated on a theoretical framework of … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 18 Jun 2012 · 7,606 accessesView PDFCite
