Research ArticleOpen accessPhrase in the titleNew Role of Sulfuric Acid In Production of Multicomponent Fertilizers From Renewable SourcesHelena Górecka, Henryk Górecki, Katarzyna Chojnacka et al.The paper discusses the possibility of using renewable sources: slaughter wastes and wood ashes in the production of NPK fertilizers. The content of macronutrients, micronutrients and toxic elements in these materials was reported. In the present work, poultry feathers were used as fertilizer source of nitrogen, animal bones as the source of phosphorus and wood ash as the source of … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPorosity Investigation of Kosova's ClayMakfire Sadiku, Naim Hasani, Altin MeleProblem statement: Acid activated clay minerals are used as catalysts in the desulphurization of crude oil or as catalyst carrier, drilling mud, bleaching earth. Approach: The efficiency of the acid activation can be described in two ways. As increase of the surface and as increase of the cumulative pore volume after the activation. Results: In different samples of the clay … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThermodynamic Characteristics of Camel’s Urine as an Inhibitor for Mild Steel in 1.5 M H2SO4 Acid SolutionEhteram A. Noor, Azza A. Al-Ghamdi, Aisha H. Al-MoubarakiProblem statement: The corrosion inhibition of mild steel in 1.5 M H2SO4 by Camel’s Urine (CU) addition was evaluated at five different temperatures in the range from 30-70°C by weight loss measurements. CU acts as a good inhibitor for the corrosion of mild steel in 1.5 M H2SO4. The value of inhibition efficiency increases with increasing both inhibitor concentration and … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 22 Oct 2011 · 7,369 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecovery of Manganese from Zinc Smelter SlagRasoul Khosravi, Rasoul Fatahi, Hossein Siavoshi, Fatemeh MolaeiUsing a software-based experiment design, the application of the leaching process for the extraction of manganese from Zinc Plant Slag (ZPS) was investigated. In this study, the effect of different parameters, i.e., H2SO4 concentration, pulp density, agitation rate, temperature and reaction time, was investigated. Response Surface Methodology (RSM) based on the Central Composite Design (CCD) has been implemented to consider … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 1 Dec 2020 · 7,273 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Different Environments on Reinforcement Concrete CorrosionMohammed Thalji Awwad, Omar Asad AhmadThis research focuses on various forms of steel bar corrosion located in different environments and the factors affecting the corrosion process, both the external (surrounding environment around concrete elements) and the internal environment (concrete itself), as well as on the investigations and tests for this type of damage, in order to develop measurements and recommendations that will reduce harmful investment … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 15 Sep 2017 · 7,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEVELOPMENT OF A BACTERIAL CULTURE SYSTEM USING A PAPER PLATFORM TO ACCOMMODATE MEDIA AND AN INK-JET PRINTING TO DISPENSE BACTERIATithimanan Srimongkon, Takuya Ishida, Kiyohiko Igarashi, Toshiharu EnomaeGenerally, bacterial culture is performed manually and is subject to error. Here, we created a novel, well-ordered and reliable system for dispensing bacteria microscopically by using paper and an ink-jet printer for controlled patterning. For paper to accommodate a culture medium, hydrophobic/hydrophilic patterns were incorporated onto the paper by immersing paper in a toluene solution of polystyrene and drying for … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 26 Apr 2014 · 7,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change Adaptation in Acid Sulfate LandscapesChuxia LinOxidation of sulfide minerals produces sulfuric acid and consequently creates Acid Sulfate Landscapes (ASLs), which represent one of the most degraded types of land-surface environments. Although acid sulfate-producing weathering is a naturally occurring process, it is markedly facilitated by human intervention. Mining is by far the dominant anthropogenic cause for the creation of inland acid sulfate footprints while land reclamation … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 7 Jul 2012 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioethanol Production from Rice StrawNutawan Yoswathana, Phattayawadee Phuriphipat, Pattranit Treyawutthiwat, Mohammad Naghi EshtiaghiProblem statement: Rice straw has been treated with different chemical (acid, alkali) and physical (subcritical water, ultrasound) methods to convert lignocellulose material to sugar. In addition enzyme treatment of pretreated samples has been applied to improve the conversion of lignocellulose material in sugar. Approach: Sulfuric acid at concentration of 1-9% was applied for acid treatment. For alkali treatment was sodium … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 18,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation and Movement of Four Potentially Toxic Elements in Soils Throughout Five Years, During and After Biosolid ApplicationMarta Susana Zubillaga, Raúl Silvio LavadoIn this research, we have studied the accumulation of four PTEs (Cadmium, copper, lead and zinc) during and after biosolid application, in two soils with different clay content and their eventual movement with depth. The study was performed in the Province of Buenos Aires, Argentina, on a Typic Argiudoll and on a Typic Hapludoll. Treatments were: control and biosolid application, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,206 accessesView PDFCite
