Research ArticleOpen accessEvery word in the titleThe Rise of Abstract Thinking in History. The Developmental Approach Illuminates the Foundations of the Russian Socio-Historical PsychologyGeorg OesterdiekhoffLuria's empirical study in Uzbekistan and Kirgistan belongs to the core of the Russian School of Socio-Historical Psychology. The goal of this article is to examine that research again and to disclose their true fundamentals. All the tests Luria had used in Central Asia come from developmental psychology. However, neither Luria nor his followers fully understood the foundations and consequences … …Journal of Social Sciences, Vol. 18, Issue 1 · 2 Apr 2022 · 8,134 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEarly Greek Astrophysics: The Foundations of Modern Science and TechnologyXenophon MoussasThe foundations of modern science and technology, metrology, experimental physics, theoretical physics, theoretical mathematics, astrophysics, including applied optics and spectroscopy go back to the Prehistoric, Presocratic, Classical and Hellenistic Greece. This tradition is well deep rooted in time, going back mainly to the epoch of the prehistoric Aegean sea, the mainland of Greece and the Islands, Cycladic, Euboea, as well … …Space Science International, Vol. 1, Issue 2 · 4 Feb 2014 · 8,679 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWind Load Effects on Manufactured Home FoundationsRamesh K. Dhungana, Taher M. Abu-Lebdeh, Ellie H. FiniProblem statement: Manufactured homes are susceptible to hurricane damage. Each year, significant losses, in terms of fatalities and property damage, are reported. There is always a prevalent concern about lateral load resistance capacity of tie-down system of manufactured homes when subjected to windstorms. This study is performed to determine the effects of hurricane wind on manufactured homes’ foundations. Approach: A … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 25 Jan 2012 · 8,329 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBIOENERGETICS, THE FOUNDATION OF THE FUTURE OF CANCER THERAPEUTICS A QUANTUM LEAP IN MAKINGKambiz AfrasiabiDeep understanding of the governing laws of bioenergetics of the living organism and dissection of their aberrancies, could enable us to design new treatment strategies for a vast array of disorders including malignancy and could potentially lead to major breakthroughs and cure of these devastating disorders. The modern treatment strategies currently aim at identification of a pathway considered to be … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 15 Aug 2012 · 7,528 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Study of Static Instability of Pipe Conveying Incompressible Fluid under Different Boundary ConditionsDahmane Mouloud, Zahaf Samir, Sid Ahmed Slimane et al.In this article, the influences of uniform velocity profile, mass ratio, length and Winkler elastic foundation on the static instability of pipe conveying incompressible fluid are investigated. The Euler-Bernoulli beam theory is employed to derive partial differential equation of pipes carrying fluid. The results were carried out using ANSYS Workbench program, where the analysis is based on the numerical solution; … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 26 Nov 2020 · 6,577 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeometrical and Physical Effects on the Instability of a Fluid-Conveying PipeDahmane Mouloud, Samir Zahaf, Benkhettab Mohamed et al.The endeavor of this paper is to calculate frequencies and critical velocity of pipe carrying incompressible fluid are obtained using standard finite element method. Finite element beam type with two degrees of freedom per node was used. The natural frequencies of our system are calculated by using a program developed on MATLAB. The results are compared with those predicted by … …Current Research in Bioinformatics, Vol. 9, Issue 1 · 2 Nov 2020 · 11,324 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Study of Post-Buckling of Clamped-Pinned Pipe Carrying Fluid Under Different ParametersDahmane Mouloud, Samir Zahaf, Mawhoub Soubih et al.This research aims to calculate the first three natural frequencies and critical velocity of a fluid-conveying pipe are obtained with numerical approach with standard finite element method and this by discretizing the structure wall and internal flow, starting from beam type with two degrees of freedom per node.
