Research ArticleOpen accessEvery word in the titleEffect of Different Cycles of Thermal Fatigue in Steel Metallurgical Aspects ASTM SA-516 Grade 60Eder Hermes Bicharra, Jorge Luis Braz Medeiros, Luciano Volcanoglo Biehl et al.The ASTM SA-516 steel has applications in compact steam boilers of low and medium temperature and pressure. Deterioration can show when exposed to high temperatures due to fuel gases burning. Failures detected by inspections done in a frequency required by standard on the boilers. Among the main failure mechanisms found in materials used in boilers, creep, corrosion, when subjected to … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,985 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Aspect Ratios and Number of Meandering Turns on Performance Limit of an Inclined Closed-Loop Oscillating Heat PipeN. Panyoyai, P. Terdtoon, P. SakulchangsatjataiProblem statement: The purpose of this research was to determine the effects of aspect ratios and number of meandering turns on performance limit of an inclined closed-loop oscillating heat pipe. Approach: The Closed-Loop Oscillating Heat Pipe (CLOHP) was made of a long copper capillary tube. The geometrical sizes, which were the variable parameters of this study, were as follows; the … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,081 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Investigation of the Effect of Aspect Ratio on the Airfoil PerformanceM. Kopaç, M. Yılmaz, T. GültopThe effect of aspect ratio on the airfoil performance is investigated for airflow about axially symetric wings as a function of the angle of attack. The magnitudes of aerodynamic forces and moments on airfoils resulting from the incompressible viscous flow fields are determined experimentally. The TE54 wind tunnel used for the experiments is an open conduit and has a 300x300 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,682 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleSome New Gears AspectsFlorian Ion Tiberiu PetrescuIn today's mechanical transmissions most widely used, the gears, are spread across all industries. For this reason, their importance has become overwhelming, which is why we want to recall in this paper some important aspects regarding toothed wheels. It is the geometry, cinematic, the forces and the yields of these mechanisms, which will be presented in the work in the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 7,077 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,020 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSocio-Economic, Health and Environmental Aspects of Child Waste Picking Activity at Africa's Largest DumpsiteAmos Oluwole Taiwo, Olanrewaju Timothy Dada, Adetola Samuel Ayoola, Gbemiga Bolade FaniranThis study examined the social, economic, health, and environmental aspects of child waste picking at the Olusosun dumpsite in Lagos, Nigeria. A questionnaire was administered through the convenience sampling technique to 150 child waste pickers. Findings showed that recovering materials from the dumpsite involved physical energy and manually-operated rudimentary tools. A majority (62.0%) of the child waste pickers were males … …American Journal of Environmental Sciences, Vol. 18, Issue 3 · 2 Jul 2022 · 7,563 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleMomordica balsamina Fruit Extracts Enhances Selected Aspects of the Insulin Synthesis/Secretion PathwayAnanias Hodi Kgopa, Leshweni Jerry Shai, Motetelo Alfred MogalePrevious studies have suggested that crude plant extracts of the anti-diabetic medicinal plant, Momordica balsamina (MB) may exert their anti-diabetic effect through either enhancement of insulin sensitivity or inhibition of intestinal glucose absorption. However, the effects of these MB extracts on insulin synthesis and secretion are not well documented in the literature. Therefore, a main purpose of the current research … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 6,999 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleSome Aspects Related to DronesRelly Victoria Virgil PetrescuDrones developed very quickly and today have come to conquer airspace even more than conventional aviation.
