Research ArticleOpen accessIn the abstractComparative Study of Soluble Sulfate Reduction by Bacterial Consortia from Varied Regions of IndiaPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriSoluble sulfate contamination in water is observed due to various industrial activities. Chemical means of reduction are available yet the biological approach is the preferred one. Problem statement: The problem addressed in this study was the isolation of efficient sulfate reducing bacterial consortia for bioremediation of soluble sulfate from mining effluent. Approach: The culture based method using the DSMZ specific … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,338 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompetition Effects of Date of Sowing and Nutsedge Removal Time on Yield and Yield Contributing Characters of Tef [Eragrostis tef (Zucc.) Trotter]Abdul Shukor Juraimi, Mahfuza Begum, Ahmed Mohammed Sherif, Anuar Abdul RahimProblem statement: Tef [Eragrostis tef (Zucc.) Trotter] is a C4 grass, most important indigenous cereal crop in Ethiopia. The average grain yield of this crop is low; averaging <0.8 Mg ha-1. Under appropriate cultural practices such as the right sowing date, sowing rate, weeding time and fertilizer application, tef could produce grain yields of 2200-4599 kg ha-1. A delay in … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 7,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractGaseous Emissions and Combustion Efficiency Analysis of Hydrogen-Diesel Dual Fuel Engine under Fuel-Lean ConditionPrateep Chaisermtawan, Sompop Jarungthammachote, Sathaporn Chuepeng, Thanya KiatiwatExhaust gas emissions from diesel engine combustion using alternative fuel may change in their quantities that can affect exhaust gas after-treatment devices and environmental ambient. This study presents theoretical analysis of combustion generated emissions and efficiency of hydrogen-diesel duel fuel in fuel-lean condition. A chemical equilibrium method by minimizing Gibbs free energy is employed to estimate exhaust gas products from … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDFCite

KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Phenolic Composition and Antioxidant Activity of Silver Nanoparticles using Aqueous Extract of Chilca Leaves (Baccharis latifolia)Fernanda Pilaquinga, Camila Granja, Eliza Jara et al.The importance of studying polyphenols as natural antioxidants has encouraged the search for new methods of rapid, simple analysis. The synthesis of silver Nanoparticles (Ag NPs) using plant extracts has been presented as an alternative to determine the presence of polyphenolic compounds. In this study, aqueous extract of chilca (Baccharis latifolia), an endemic plant species from South America known for … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 16 Apr 2021 · 8,341 accessesView PDFCite
EditorialOpen accessIn the abstractVolume 3: SGAMR is Always on Track!Chiara Bedon, Mario D’Aniello, Flavio StochinoThe year 2019 represents a new growing step for SGAMR, that starts to publish “continuously” all the accepted papers, once they are subjected to positive, blinded peer-review process. This is a further effort to improve the service for the contributors and for the readers, given that the efficiency of the journal to share knowledge can be maximized. Hänig et al. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 28 Aug 2020 · 5,711 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Gas-Phase Mass Transfer Coefficients in a Humidification Column through Random PackingMasoud Khorasani, Morteza Zivdar, Farshad Fashchi Tabrizi et al.Packed columns are an important part of the broad selection of mass and heat transfer equipment. Nowadays, the use of packed columns is increasing, which is because of its lower pressure drop, higher capacity and higher mass transfer in comparison to tray columns. The experiential tests and the hypothetical analysis display that the chemical dehumidification of air by hygroscopic salt … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Jul 2019 · 8,028 accessesView PDFCite
