Research ArticleOpen accessIn the abstractFabrication of Ni, Si and Mg Supersaturated Solid Solutions in Al by Mechanical AlloyingA. Sedano, A. Molina, S.A. Serna et al.In this work, a comparison between the synthesis process of nanostructured Al base alloys modified with Si, Ni and Mg and the formation of their respective supersaturated solid solution is presented. The samples were obtained via Mechanical Alloying (MA) at a speed of 300 RPM for 2, 5, 10, 20 and 30 h under an inert Ar atmosphere. Lattice parameter … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 23 Feb 2020 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Variability of Indonesian Throughflow in Sumba Strait and Its Linkage to the Climate EventsAhmad Bayhaqi, Yueng-Djern Lenn, Dewi Surinati et al.As one of the Indonesian Throughflow (ITF) outflow passages, the Sumba Strait is a meeting point for the Pacific and the Indian Ocean water mass. In order to study the long-term variability of ITF flowing via Sumba Strait, this research uses observational data from the Ekspedisi WIdya Nusantara (EWIN) research cruise conducted in August 2016 to validate the altimetric geostrophic … …American Journal of Applied Sciences, Vol. 16, Issue 4 · 12 Jun 2019 · 8,830 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantitative Analysis of the Pb Concentration in Dust Fall in Zahedan in the Winter of 2014Sara Abdollahi, Akram Karimi, Meysam Madadi et al.Dust is considered as one of the atmospheric phenomena that inappropriately influences the environment. Falling dust contains particles with the size of 100 microns or less, which falls from atmosphere on the surface of the earth. This study aimed at determining the Pb concentration in falling dust samples in order to investigate the urban pollution caused by this element. To … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 7,988 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Chlorophyll-an in a Small Reservoir by Landsat 7 ImageryMaryam Ghashghaie, Kaveh Ostad-Ali-Askari, Saeid EslamianChlorophyll-a (chla) is a source of water pollution. Monitoring the quality of water in reservoirs is necessary to take any action for protecting the water quality. Traditional methods of sampling are usually costly and time consuming. Also they need skillful labors and some areas are out of reach or sampling at those areas is dangerous. Remote sensing technology could solve … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 8,330 accessesView PDFCite
