Research ArticleOpen accessIn the keywordsEffect of Y2O3 Additions on Microstructure and Properties of Alumina–Magnesia CeramicsAurawan Rittidech, Pimpun Wisuwan, Thitima PinkhunthodThe purposes of this research are to prepare and investigate the characterization of 0.7MgO-xY2O3-(99.3-x)Al2O3 by varies x at 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 wt% (AMY). AMY samples were synthesized by solid state reaction under two different sintering methods conventional sintering method (NS) and two stage sintering method (TS). Ceramic samples were sintered by conventional sintering at 1600°C for … …American Journal of Applied Sciences, Vol. 15, Issue 8 · 30 Oct 2018 · 8,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractClassification and Spatial Distribution of Macronutrients and Micronutrients in the Soil of Greenhouse Sweet CherriesLijin Qin, Qingxiang Wang, Yongli Lv et al.To understand the distribution of trace elements in the soil of greenhouse sweet cherry, using soil samples from solar greenhouse sweet cherry orchards in Chifeng, Inner Mongolia as the object, the trace element indicators in the soil of different sweet cherry production areas were analyzed using the "S" shaped 5-point sampling method. Descriptive statistics were conducted. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 9 Oct 2025 · 2,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrography and Geochemistry of Orin-Ekiti Basement Rocks, Southwestern Nigeria: Implications on BauxitizationAbel Ojo Talabi, Akin Ojo Oyinloye, Olusola Amos Olaolorun et al.The petrography and geochemistry of Orin-Ekiti Basement rocks were evaluated to determine their mineralogical and chemical composition, assessed their petrogenesis and susceptibility to the formation of bauxitic clay. Ten representative rock samples were selected for thin section petrography and bulk rock geochemical analysis using Petrographic microscope and XRF, Rh Tube, 3k Watt respectively. Field observations revealed charnockites as the dominant … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 1 Jan 2018 · 8,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Activated Carbon from Eggshell Membranes Prepared Using Sodium Acetate and Zinc Metal ActivationSumrit Mopoung, Kanjana JitchaijaroenkulThe eggshell membranes of ducks and hens were carbonized or activated with 4 wt% sodium acetate or zinc at 400-600°C. The carbonized or activated products were characterized by SEM-EDS, TEM, FTIR and XRD. It was found that the suitable activation temperature for eggshell membranes is 500°C with 30.03-35.26% yield. The activation performance of CH3COONa for eggshell membrane activated carbon production … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 2 Aug 2017 · 8,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractCryptic Mantle Metasomatism: Evidences from Spinel Lherzolite Xenoliths/Al-Harida Volcano in Harrat Al-Shaam, JordanAhmad Al-MalabehProblem statement: Al-Harida volcano is located in the Jordanian parts of the Harrat Al-Shaam plateau and contains considerable amounts of mantle xenoliths within its pyroclastic successions. Approach: These xenoliths are reported for the first time for this area. Mineralogical investigations show that they are composed of olivine, orthopyroxene, clinopyroxene, spinel and phlogopite. Results: The xenoliths range in size from 5-30 … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical, Petrographic and Magnetic Characteristics of Spinel Lherzolite Mantle Xenoliths from Jabal Remah Volcano, JordanAhmad Al-Malabeh, Tayel El-Hasan, Mahdi LataifehPeridotite ultramafic mantle xenoliths are occurring abundantly in the Harrat Al-Shaam basaltic province. Jabal Remah volcano is located in the Jordanian parts of the plateau and contains considerable amounts of mantle xenoliths within its pyroclastic successions. Mineralogical investigations show that the xenoliths are mostly of the spinel lherzolite type, which are characterized by a protogranular texture. Modally, the xenoliths are … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of Ni/Dolomite Catalyst in Simultaneous Biomass Gasification and Reforming in Fluidized BedAnawat Ketcong, Tharapong Vitidsant, Kaoru FujimotoSimultaneous gasification and steam reforming of the biomass on Ni/dolomite catalyst in fluidized bed reactor were studied in the gaseous production in the one stage reactor.

Research ArticleOpen accessIn the abstractEvolution of Biochemical Parameters During Composting of Various Wastes CompostN. Saidi, M. Cherif, N. Jedidi et al.In Tunisia the most treatment waste is landfill (50% of wastes were land filled) and only 5% are composted. And since our soil become more and more poor in organic matter, green waste can be a significant source of organic matter; in parallel we cited the domestic waste and dead posodonia collected from beaches. All these wastes coming from various … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,933 accessesView PDFCite
