EditorialOpen accessIn the abstractEditorial Commentary: Challenge of Non–AIDS-Defining Cancers (NADCs), Focusing on Trans Activation Response Element (TAR) RNA Embedding ExosomesLechuang Chen, Ge JinGlobally, 37.9 million people were living with HIV at the end of 2018 (Organization, 2018). Cancer is a major cause of mortality and morbidity in AIDS patients and chronically HIV-infected people. With the aid of combination Antiretroviral Therapy (ART), people living with HIV (PLWH) have a longer life span. However, because the virus is not completely eradicated, PLWH under antiretroviral … …American Journal of Immunology, Vol. 15, Issue 1 · 28 Nov 2019 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractCritical Study of Several MPPT Techniques for Photovoltaic SystemsBennacer El Hassouni, A. Haddi, A.G. AmraniThis paper presents a critical study of Maximum Power Point Tracking (MPPT) techniques for photovoltaic systems. After a brief introduction of the key factors for power extraction of photovoltaic panels, a review of commonly used MPPT techniques is presented and detailed with a holistic approach. Then, a comparison of these techniques is made according to several parameters such as robustness, … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 20 May 2019 · 6,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractDreams, Possibilities and Necessity of Public Education through Urban Students’ Eyes: It is the ClimateDolapo Adeniji-Neill, Devin G. ThornburgSchool climate is the quality and character of school life. It provides a shared sense of purpose, as well as norms and values that may serve to bind or tear apart the fabric and foundation of a school. In a broader sense, school culture is based on the partnership, cohesiveness and collaborations between “town and gown”—a colloquial term referring to … …Journal of Social Sciences, Vol. 14, Issue 1 · 21 Mar 2018 · 8,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty Analysis of Time of Concentration Equations based on First-Order-Analysis (FOA) MethodAsghar AzizianThe time of concentration (Tc) is one the most important time parameters to predict the response of a catchment to a given rainfall and plays a key role in the hydrologic design and rainfall-runoff modeling. There are a huge number of empirical/semi-empirical equations for estimation of Tc and depending on several parameters such as rainfall attributes, topographic and land cover … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 19 Mar 2018 · 9,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the E-Learning Acceptance in Oman: Application of Structural Equation Modelling ApproachSalim Amor Al-Hajri, Syed Ghayas, Abdelghani EchchabiSimilar to many developing countries, Oman recognizes the importance of e-learning and Information Communication Technology (ICT) to enhance the higher education standards and compete in the global education markets. Many higher education organizations today expect e-learning to add value to their organization and hence improve the economy by extending their educational services to students and other students who are not … …Journal of Computer Science, Vol. 14, Issue 3 · 17 Mar 2018 · 8,400 accessesView PDFCite

Research ArticleOpen accessIn the abstractAcademic Motivation to Learn English in a Malaysian private UniversityAhmed Fahim YoussefMotivation is accepted as one of the key factors in promoting second language teaching and learning. The study is based on the Self Determination Theory (SDT) developed by Deci and Ryan who were greatly interested in both the quantity and the quality of motivation. They categorized motivation from the unmotivated to the motivated and in between there are many levels … …Journal of Social Sciences, Vol. 12, Issue 4 · 15 Dec 2016 · 8,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne-Dimensional Simulation of Diffusion and Advection Effects in Enzymatic Hydrolysis of CelluloseNorazaliza Mohd Jamil, Qi WangEnzymatic hydrolysis process to transform lignocellulosic cellulose into sugar in a bioreactor tank involves different controlling factors such as advection, diffusion and fragmentation of cellulose chains. Although it has been observed experimentally that enzymatic hydrolysis is strongly influenced by the environmental effects in a tank, these effects have not been adequately quantified. In this study, a current kinetic model for … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 13 Jul 2016 · 7,220 accessesView PDFCite
