Research ArticleOpen accessIn the abstractHas The Sea Changed? Qualitative Analyses on the Views of Fishermen in the east coast zone of PeninsularHayrol Azril Mohamed Shaffril, Bahaman Abu Samah, Jeffrey Lawrence D’Silva, Jegak UliProblem statement: Pressure from the uncontrolled human activities had caused damages to our environment. The sea, as one of the environment components has also suffered from these activities. Fishermen, whom depend on the sea for their income and sources of protein, can be one of the groups who are suffering the most. This study intends to discover the perception of … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 2 Nov 2011 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Water Properties and Geostrophic Currents in Fiji Waters Before and After Tropical Cyclone GeneShivneel Prasad, Than Aung, Awnesh SinghProblem statement: Water properties influence ocean primary production and drive the ocean food chain. This study depicts changes in temperature and salinity and its effects on geostrophic currents near Fiji before and after Tropical Cyclone (TC) Gene. Approach: Available Argo float data from 6 January-4 February 2008 were used for analysis since TC Gene passed the area on 28 January … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,949 accessesView PDFCite

Research ArticleOpen accessIn the abstractProduction of Al based Composites Reinforced with FeAl Intermetallic Particles by Mechanical AlloyingSergio Rubèn Gonzaga Segura, Arturo Molina Ocampo, Renè Guardián Tapia, Alejandro Sedano AguilarIn this research project, Al matrix composite materials reinforced with 5 and 10 (wt. %) of FeAl intermetallic particles were synthesized by Mechanical Alloying (MA) at a speed of 250 RPM for 2, 5, 10 and 15 h of milling time. The results showed that composite materials can be obtained at low energy conditions with improved dispersion of the reinforcement … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 24 Mar 2021 · 6,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractXPS Studies of the SiO2 Substrates and Thermoelectric Thin Films of Sn/Sn+SnO2 under the Effects of the Different Thermal TreatmentsRichard Lagle, Stephen Egarievwe, Satilmis Budak, Mebougna DraboMultilayered thermoelectric Sn/Sn+SnO2 thin films were prepared using KJL DC/RF magnetron sputtering system under Ar gas plasma on the SiO2 substrates. The thicknesses of the fabricated thin films were found using Filmetrics UV thickness measurement system. The fabricated thin films were annealed at different temperatures for one hour to tailor the thermoelectric properties. In this study, unannealed, annealed at 150 … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 8,212 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoles of Macroeconomic Variables on Agricultural Diversification in NigeriaSunday B. Akpan, Samuel J. Udoka, Inimfon V. PatrickThe study examined the trend in agricultural diversification index from 1960 to 2014 in Nigeria. It also determined the influence of some macroeconomic variables on the estimated index. Augmented Dickey-Fuller-GLS unit root test showed that all series were integrated of order one. The long-run and short-run elasticity of the agricultural diversification index with respect to the specified macro-economic variables were … …American Journal of Economics and Business Administration, Vol. 7, Issue 2 · 9 Jul 2015 · 7,496 accessesView PDFCite
