Research ArticleOpen accessIn the abstractEffect 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 accessIn the abstractTemporal Variations in Abundance and Species Richness of Zooplankton with Emphasis on Ichthyoplankton in the Subtidal Waters of Umm Al-Namil Island, Northwestern Arabian Gulf of the ROPME Sea AreaMohammad Ali, Matrah Al-Mutairi, M.N.V. Subrahmanyam et al.Zooplankton, including the ichthyoplankton, abundance and species richness over time in the subtidal waters of Umm Al-Namil Island, Kuwait Bay, were sampled and quantified from September 2016 to August 2017. At the same period, physicochemical measurements (i.e., water temperature, pH, salinity, dissolved oxygen and nutrient concentrations) occurred. A total of 9 larval fish families were identified: Acropomatidae, Bregmacerotidae, Bythitidae, Clupeidae, … …American Journal of Environmental Sciences, Vol. 15, Issue 6 · 21 Jan 2020 · 7,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated ARIMA and Multi-Scale GRU for Crop Recommendation and Yield Prediction in Precision AgricultureVani Vijay Kumar Ballapuram, Gurupraksh Chirathahalli DyamannaAgriculture is the fundamental source of food, income, and livelihood for rural communities in India. Numerous crops are affected due to the lack of technical decision-making support and variations in weather patterns, temperature, rainfall, and atmosphere factors, which play a critical role in defining crop yield. Hence, choosing the appropriate crop to maximize yield is key to enhancing real-time farming … …Journal of Computer Science, Vol. 21, Issue 10 · 26 Nov 2025 · 2,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Seasonal Variations on Typha capensis and Heliconia psittacorum in the Remediation of Heavy Metals from Soil and WaterWiafe Samuel, Buamah Richard, Owusu MichaelDifferent plant species have been used in the remediation of different heavy metals. The performance of a macrophyte to remediate heavy metals may be dependent on a lot of factors which may include water chemistry, metal solubilityand temperature. The objective of this research was to ascertain the effects of seasonal variations on the remediation of heavy metals. To this end,two … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 31 Jan 2019 · 7,787 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation and Optimization of Perovskite Type Micro Thermoelectric GeneratorJeyashree Yesuraj, Vimala Juliet Ashokan, Sukhi Yesuraj, Rebecca Shirly Harrison ChristleyIn this study the thermoelectric properties of perovskite type Ca-Mn-O3 compounds are estimated for the operating range of 850-1150 K. The optimization of design module for maximum power output is obtained using the analytical expression for power of Thermoelectric Generator (TEG). For the optimum length of 1.4 μm and with a cross sectional area of 0.3×0.3 μm the power obtained … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 26 Nov 2016 · 7,381 accessesView PDFCite
