Research ArticleOpen accessEvery word in the titleThe Application of Numerical Taxonomy Technique in the Iron Ore Flotation to Determine Appropriate pH and Particle Size DistributionRasoul Khosravi, Fahimeh Dehghani, Hossein Siavoshi et al.The numerical taxonomic technique is one of the multivariate decision-making techniques for assessment and ranking. It is widely used for planning and development studies. In this research, flotation experiments were conducted for Band Narges mine iron ore using different pH and particle size ranges. Numerical taxonomy technique, as one of the most important multi-attribute decision-making techniques, was used to determine … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 24 Dec 2020 · 6,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Insights into the Pre-Concentration of Alunite from a Siliceous ore using Froth FlotationFahimeh Dehghani, Halimeh Askari-Sabzkoohi, Tathagata GhoshAlunite is the main non-bauxite source of aluminum. Due to the low Degrees Of Freedom (DOF) of alunite, froth flotation, as a pre-concentration method, is a viable alternative to increase selectivity in downstream processes. The current study was aimed at investigating the pre-concentration of alunite using micro-flotation. In the first step, an optical microscope studies were done to determine DOF … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 20 Dec 2020 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdsorption Kinetic of 8-Hydroxyquinoline on MalachiteGabriela OPREA, Angela MICHNEA, Cristina MIHALIInfluence of temperature and collector concentration on its adsorption rate on mineral surface was studied as regarding to the 8-hydroxyquinoline/malachite system. Theoretical equations as well as experimental data may be useful to estimate the adsorption rate and kinetics connected to the conditioning stage in mineral flotation in order to optimise the selectivity and the recovery of the desired mineral. …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,612 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation and Beneficiation of Feldspar from Arkosic Sandstone in South Jordan for Application in the Ceramic IndustryMousa GougazehThe main purpose of the present study was to investigate the beneficiation and upgrading processes of a Jordanian feldspar ores to be finally implemented in the ceramic industry. The experimental work was conducted to evaluate the role of particle size distribution, chemical composition, mineral content and the magnetic impurities (Fe2O3 +TiO2 contents). The beneficiation of the 500-45 μm fractions, which … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence of Giardia duodenalis in Household and Shelter Cats in Almaty, South-Eastern KazakhstanLyudmila Lider, Altay Ussenbayev, Vladimir Kiyan et al.Giardia duodenalis is a widely distributed protozoan parasite, that causes acute gastroenteritis in many animal species and humans all over the world. We aimed to carry out a cross-sectional study to determine the prevalence of G. duodenalis among cats in Almaty City, Kazakhstan. A total of 164 fecal samples from different origin cats (household, sheltered) in two veterinary clinics and … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 23 Aug 2024 · 5,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Supplementation of a Mix of Chestnut and Quebracho Tannins on Intestinal Morphology, Bacterial Load, Eimeria spp oocyst Excretion and Immune Response after Vaccination in RabbitsFrancesca Parisi, Simone Mancini, Maurizio Mazzei et al.Among plant products, tannins exhibited a strong antioxidant activity and their employment was studied as food or feed addictive with positive effects. Nevertheless, their health-enhancing properties remain to be completely clarified, particularly in rabbits. The aim of the present study was to investigate the influence of a mix of chestnut and quebracho tannins as supplementation in rabbit diet on intestinal … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 3 · 3 Aug 2018 · 8,619 accessesView PDFCite
Research ArticleOpen accessIn the abstractEimeria Legionensis and Eimeria kofoidi (Apicomplexa: Eimeriidae) Infection and Associated Lesions in Naturally Infected Red-Legged Partridges (Alectoris rufa)G. Fichi, G. Rossi, Stefania PerrucciWith the aim to identify the Eimeria species responsible for coccidiosis in 50 deceased red-legged partridges (Alectoris rufa), individual faecal samples were collected, dissolved in 2.5% K2Cr2O7 solution and maintained at room temperature to allow sporulation of the oocysts. Morphology and dimensions of sporulated oocysts were microscopically evaluated. To assess Eimeria intestinal localisation, faecal samples and scrapings taken from the … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 4 · 9 Nov 2017 · 7,689 accessesView PDFCite
Research NotesOpen accessIn the abstractGastrointestinal Parasites of Cattle in Central JavaPenny Humaidah Hamid, Yuli Purwandari Kristianingrum, Joko Prastowo, Liliana Machado Ribeiro da SilvaGastrointestinal parasites are the main cause of losses of cattle farms including feed conversion-failure and even death of heavily infected animals. We have conducted a random examination of 455 cows in the Special Region of Yogyakarta-Central Java from March to June 2016.
