Research ArticleOpen accessEvery word in the titleBacteria of the Clostridium Genus, Methane and Hydrogen Sulfide in Sulfide Mud of the Taman Peninsula ReservoirsYury Aleksandrovich Fedorov, Gar'kusha Dmitry Nikolayevich, Roman Gennad'yevich TrubnikThe features of the distribution of the concentrations of hydrogen sulfide, methane and the number of sulfite-reducing clostridia in the mud of the Bugazsky, Kiziltashsky and Vityazevsky limans and Chembursky lake were studied, and their physiological and chemical conditions and levels of anthropogenic loading were assessed. The tendency of reduction of the content of the studied reduced gases from the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 Aug 2018 · 7,090 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGamma Irradiation Synthesis and Influence the Optical and Thermal Properties of Cadmium Sulfide (CdS)/Poly (Vinyl Pyrolidone) NanocompositesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng, Elias SaionProblem statement: Gamma irradiation has been successfully used to prepare a spherical cadmium sulfide CdS/Poly Vinylpyrolidone (PVP) quantum dots nanoparticles with enhancement of their optical band gap energy and thermal properties at room temperature and under ambient pressure. Sodium thiosulfate was used as a sulfur source in an aqueous solution. The formation of lower band gap energy of CdS/PVP nanoparticles … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,465 accessesView PDFCite
InvestigationOpen accessIn the keywordsRecovered Gases and Bacteria from the Clostridium Genus as Ecological Condition Indicators of Bottom Sediments of the Eastern Donbass Small RiversRoman Gennad'yevich Trubnik, Yuriy Aleksandrovich Fedorov, Ludmila Anatol'yevna NedosekaThe results of determination of methane, total hydrogen sulfide and sulfite reducing clostridia in bottom sediments of small rivers and reservoirs of the Eastern Donbass are presented. The horizontal and vertical distribution of levels of reduced gases in bottom sediments is analyzed. The ecological condition of the bottom sediments was estimated by the clostridia titer and the methane index. The … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 27 Jul 2017 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the keywordsINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Review of Static Tests and Recent StudiesSrilert ChotpantaratProblem statement: Acid mine drainage from waste rocks, tailings and other mine components, is one of the most important environmental concerns at mining sites. To attempt to determine the balance between the acid and neutralization potentials of the material and evaluate the possible acid-forming potential of mine waste, many static prediction tests have been developed to evaluate the acid-forming potentials … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 19 Apr 2011 · 7,669 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOil Refineries Emissions Impact on Urban Localities Using AERMODAmira Mohamed Wahba Abdelrasoul, Amir AL-Hadad, Abdul Rehman KhanProblem statement: The absolute necessity of compulsory fuel utilities, no matter small or big has resulted into substantial high hazards pollutants. Petroleum refineries are major industrial installations that are necessary for providing the best suited fuel for various necessary utilities, but are responsible of the emission of several hazardous pollutants into the atmosphere. Hydrocarbons are among the most perilous air … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular-Biological Properties of the Attenuated Strain of Salmonella Abortus-Equi E-841, used in the Creation of a Vaccine against Abortion of MaresAssiya Mussayeva, Natalya Yegorova, Merey Yerishov et al.Salmonella abortion of mares takes a leading place in the in factious pathology of horses and leads to the abortion of pregnant mares and infected stallions become salmonella carriers. The disease with salmonella abortion manifests itself in the last months of pregnancy, maybe-during the mass foal of mares-in the spring.

Research ArticleOpen accessIn the abstractPathologies of Acute Interstitial Pneumonia in Feedlot CattleJose A. Valles, Michael D. Apley, Chris D. Reinhardt et al.Acute Interstitial Pneumonia (AIP) is a costly issue that affects feedlot cattle. Research has yet to elucidate the etiology of AIP; therefore a case-control study was conducted to evaluate possible management and physiological factors that contribute to AIP in feedlot cattle. The experiment was conducted during the summer of 2011 in a commercial feedyard in Kansas.
