Research ArticleOpen accessIn the abstractA Novel River Meander Migration and Cutoff Model: A New PerspectiveYoussef Ismail HafezAccurate prediction of river meander migration is crucial for effective river management and operation, particularly in light of climate changes and human-induced interventions. Existing models often rely on single-equation approaches, such as bank erosion rate versus excess bank velocity or excess bank shear stress, which limit their ability to comprehensively capture the complex dynamics of meander evolution. This study presents … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 21 Mar 2025 · 7,683 accessesView PDFCite
Review ArticleOpen accessIn the abstractCritical Barriers in Software Outsourcing Vendor Organizations and Their Impacts on Software Outsourcing Clients: A Systematic Literature ReviewIsmail Keshta, Ammar OdehGlobalization and technological advancement have driven up the demand for software as many enterprises seek to gain a competitive edge through efficient business operations. Whereas software provides this capacity, the resources involved in software development sometimes provide a stumbling block, especially for startups and smaller businesses. Software development outsourcing or offshore software development offers a viable alternative for these enterprises. … …Journal of Computer Science, Vol. 16, Issue 10 · 5 Oct 2020 · 7,071 accessesView PDFCite

Research ArticleOpen accessIn the abstractMMP-9 is a Potential Prognostic Marker of Left Ventricular Remodeling in Patients with Coronary Artery DiseaseMikhail Aleksandrovich Popov, Anastasia Vladimirovna Poznyak, Dmitry Valerievich Shumakov et al.Matrix Metalloproteinase-9 (MMP-9) emerges as a promising prognostic marker for assessing left ventricular remodeling in patients with coronary artery disease, particularly in the context of Ischemic Heart Disease (IHD) complicated by left ventricular aneurysm. In this study, we conducted two parallel investigations to explore the prognostic significance of MMP-9 in patients with multivessel coronary artery disease undergoing left ventricular reconstruction … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 11 Jul 2024 · 4,310 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 · 6,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach to a Self-Organizing Federation of MQTT BrokersNicolas Kolling Ribas, Marco Aurélio SpohnIn the Publish/Subscribe (PS) communication paradigm clients producing content (i.e., publishers) send it to a broker, which relays the content to consumers (i.e., subscribers). Communication can happen asynchronously, leaving all the hurdles to the server/broker. MQ Telemetry Transport (MQTT) is the most used P/S protocol in designing IoT applications. The usual MQTT scenario comprises a single broker, making it a … …Journal of Computer Science, Vol. 18, Issue 7 · 29 Jul 2022 · 6,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractFailure Mode and Pullout Capacity of Anchor Piles in ClayYanbing Zhao, Haixiao Liu, Mengyuan LiuAnchor piles are wildly adopted in mooring systems. However, there are still challenges in predicting the failure mode and pullout capacity of the pile. Previous Finite Element (FE) analysis was all based on the traditional small strain FE analysis. The whole pullout process of the pile cannot be simulated. Hence, the failure mode of the pile is hard to be … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 27 Sep 2017 · 8,216 accessesView PDFCite
EditorialOpen accessIn the abstractChoice Meaning and Context: Two Sides of the Same Coin?Saadettin Sel, Joachim Storsberg, Mark A. Brown, Christian SchmidtThe human intellect is a powerful instrument to be applied to problems. Expressed differently, sharpening one’s acumen by regular exposure to conundra can be likened to exercising a muscle or refining a tool such as creating brushes to suit certain tasks. Such applications hinge on a reasonable understanding of a given problem and the presentation of opposing viewpoints of the … …American Journal of Immunology, Vol. 13, Issue 2 · 24 May 2017 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractMercury Contamination within Protected Areas in the Brazilian Northern Amazon-Amapá StateRossana Venturieri, Marcelo Oliveira-da-Costa, Cecile Gama, Christoph Bernhard JasterMercury contamination is a long-standing environmental and social problem, notably in the Amazon. The widespread use of mercury in artisanal and small-scale gold mining has driven contamination of the environment and the people, threatening biodiversity, human health and livelihoods of traditional populations. Along the border area between Brazil and French Guiana, illegal gold mining is considered a critical threat to … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 17 Jan 2017 · 9,246 accessesView PDFCite
