Research ArticleOpen accessIn the abstractPredicting Smartphone Addiction in Teenagers: An Integrative Model Incorporating Machine Learning and Big Five Personality TraitsJacobo Osorio, Marko Figueroa, Lenis WongSmartphone addiction has emerged as a growing concern in society, particularly among teenagers, due to its potential negative impact on physical, emotional social well-being. The excessive use of smartphones has consistently shown associations with negative outcomes, highlighting a strong dependence on these devices, which often leads to detrimental effects on mental health, including heightened levels of anxiety, distress, stress depression. … …Journal of Computer Science, Vol. 20, Issue 2 · 29 Dec 2023 · 8,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance, Carcass Traits and Quality of Longissimus lumborum muscle of Santa Inês lambsFabio Borba Ferrari, Juliana Lolli Malagoli de Mello, Rodrigo Fortunato de Oliveira et al.The aim of this research was to evaluate carcass traits and meat quality of finishing lambs in pastures with different leaf area index with or without high protein-mineral supplementation. In this study, forty-eight young Santa Inês rams were used, with an average initial body weight of 13.5 kg and an average age of 4 months. For approximately 10 h a … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 1 · 11 Jan 2020 · 7,190 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout HelicoptersRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine-driven rotors. In contrast with fixed-wing aircraft, this allows the helicopter to take off and land vertically, to hover and to fly forwards, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 3 · 9 Sep 2017 · 15,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Environmental and Socio-Economic Risk Factors of Climate Vulnerability in Low-Income Settlements of Kitwe City in ZambiaGeorge Kasali, Julius Kanyembo, Mapenzi Phiri, Mainza SibajeneRecent findings of the Intergovernmental Panel on Climate Change have clearly shown that climate change represents an urgent and irreversible threat to human societies and the planet and especially to the social and economic development of Africa.Therefore, the purpose of this study was to determine and identify the risk factors associated with climate vulnerability in selected slum settlements of Kitwe … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 25 Mar 2017 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation on Performance Improvement in Tube Inserted with Delta Winglets on Discrete Right-Angled Triangular PlatesAmnart Boonloi, Withada JedsadaratanachaiNumerical investigations on flow topology and heat transfer behavior in a round tube heat exchanger inserted with Delta Winglets (DW) on Discrete Right-angled Triangular Plates (DRTP) are performed. The influences of DW heights; b/D or BR = 0.05-0.25 and flow directions; DW with V-Downstream (DWVD) and DW with V-Upstream (DWVU), are studied for turbulent flow; Re = 3000-10,000. The finite … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 16 Mar 2017 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Channel Propagation Models and Developed Model for Mobile CommunicationYahia ZakariaPropagation models represent a solidifying of mathematical equations and algorithms that are used for radio signal propagation prediction in specific regions. In this research different propagation models are analyzed and compared. These propagation models have been proposed at the operating frequency of 3.8 GHz for different transmitter antenna heights in all types of terrain. These propagation models depend on location, … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 25 Feb 2017 · 8,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF THE ADEQUACY OF THE WIND SPEED EXTRAPOLATION LAWS FOR TWO DIFFERENT ROUGHNESS METEOROLOGICAL SITESDalila Khalfa, Abdelouaheb Benretem, Lazher Herous, Issam MeghlaouiIncreasing knowledge on wind shear models to strengthen their reliability appears as a crucial issue, markedly for energy investors to accurately predict the average wind speed at different turbine hub heights and thus the expected wind energy output. This is particularly helpful during the feasibility study to abate the costs of a wind power project. The extrapolation laws were found … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 1 Feb 2014 · 7,439 accessesView PDFCite
