Research ArticleOpen accessIn the abstractThermal Stability Analysis in a Two-Step Reactive Cylindrical StockpileR.S. Lebelo, R.K. Mahlobo, K.C. MoloiThermal stability analysis in a cylindrical stockpile of reactive material undergoing a two-step low-temperature oxidation reaction is studied in this article. The reactant consumption in this case is neglected and heat transfer with thermal stability are investigated by application of the energy equation. The complicated combustion process results with nonlinear interactions and hence the nonlinear partial differential equation governing the … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 6 Dec 2017 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Intelligent Household Fruit Vinegar Fermentation Device and Optimization of Key ParametersXinpeng Dai, Xiaoxue Xing, Lin Liu et al.Compared with carbonated beverages, fruit vinegar was gradually becoming more favored by consumers, because of their higher nutritional functions. But its popularization was limited by higher selling price. This article described a fruit vinegar fermentation device that can be used at home and also introduced the design principles, composition and operation methods. Furthermore, taking apple vinegar as an example, the … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 24 Aug 2018 · 10,837 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Copper from Aqueous Solution using Tunisian ClayN. Boujelben, S. Gharab, F. Bouhamed et al.Natural adsorbents such as clay was used to replace expensive imported synthetic adsorbents. In this study, Scanning Electron Microscopy (SEM), Infrared spectroscopy and X-ray diffraction techniques were used to characterize the used sorbent (clays C). Batch experiments were performed to evaluate the effects of contact time, solution pH and temperature on copper removal onto used sorbent from aqueous solution. Equilibrium … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 15 Jun 2015 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Gas Velocity and Temperature on Nitric Oxide Conversion in Simulated Catalytic ConverterSathaporn ChuepengProblem statement: Gaseous emissions from gasoline engine such as carbon monoxide, unburned hydrocarbon and nitrogen oxides were usually reduced in three-way catalytic converter simultaneously around theoretical fuel and air combustion. Engine speed and load and other parameters were varied over a wide range of operating conditions, resulting in different exhaust gas composition and condition intake into catalytic converter. This work … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 27 Jun 2012 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Adsorption of the Lead (II) by the Nonliving Biomass Spirogyra neglecta (Hasall) KutzingModher A. Hussain, Aishah Salleh, Pozi MilowProblem statement: Conventional techniques for removing dissolved heavy metals are only practical and cost-effective when applied to high strength wastes with heavy metal ion concentrations greater than 100 ppm. The possibility of using a nonliving algal biomass to solve this problem was carried in this study. Lead (II) was used in this study because it had been reported to cause … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of the Application of Sewage Sludge and Presence of Pesticides on the Development of the Microbial Population of the Soil and on the Transformation of Organic Carbon and Nutrient ElementsM.E. Sánchez, I. B. Estrada, O. Martínez et al.The laboratory trial consisted in incubating samples of soil and soil treated with sewage sludge, with the application of organophosphate pesticides with different active ingredients under controlled conditions of temperature and moisture. On the basis of a previous study of the influence of the application of sludge on the degradation of pesticides in the soil, a kinetic study is included … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractSomething about the Mechanical Moment of InertiaFlorian Ion T. Petrescu, Antonio Apicella, Aversa Raffaella et al.In this study, the relations to determining mass moments of inertia (mechanical) for different mass and mechanical inertia corresponding to geometric shapes, objects and profiles are explored. The formulas for calculating the mass moments of inertia (mechanical) for various bodies (various geometrical forms), to certain major axis indicated (as the axis of calculation) are presented. The total mass M of … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 4 Nov 2016 · 11,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimisation of Bromelain Enzyme Extraction from Pineapple (Ananas comosus) and Application in Process IndustryResmi Mohan, Venkatasubramanian Sivakumar, Thirumalaisamy Rangasamy, Chellappa MuralidharanBromelain is a general name for a family of sulfhydryl proteolytic enzymes obtained from Ananas comosus, the pineapple plant. The objective of the present study is to compare the activity of Bromelain from pineapple fruit and peel and to check the efficiency of this crude Bromelain enzyme in unhairing step in leather processing. The crude Bromelain was extracted and activity … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 19 Sep 2016 · 12,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntracellular L-Asparaginase from Bacillus sp. PG02: Purification, Biochemical Characterization and Evaluation of Optimum pH and TemperatureFatemeh Izadpanah Qeshmi, Mahsa Rahimzadeh, Sedigheh Javadpour, Manijeh PoodatBacterial L-asparaginases are amidohydrolases that act on L-asparagine and produce L-aspartate and ammonia. These enzymes have been used in treatment of lymphoblastic leukemia. In the present study, a novel strain, Bacillus sp. PG02 was explored for the production of intra-cellular L-asparaginase enzyme. The nitrogen source for L-asparaginase production was L-asparagine. New intracellular L-asparaginase was purified using ion exchange chromatography and … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Nov 2015 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractTESTING CARBOXYMETHYL CELLULASE ACTIVITY SECRETED BY TRICHOPHYTON TERRESTRE IN CARBOXYMETHYL CELLULOSE SOLUTIONMansoor Ahmad Lone, Sanjay Sahay, Ravinder, DeepakThe techniques employed for bioconversion of cellulosic biomass to simple sugars by cellulases have a great industrial brunt. Cold-adapted microorganisms are potential resource of cold-active carboxymethyl cellulases secluded from the cold regions. In this study, Trichophyton terrestre-a rare fungal species in Indian soils, isolated from the rhizosphere of Juglans regia L. during winter season was subjugated for the production and … …Current Research in Microbiology, Vol. 5, Issue 1 · 4 Feb 2015 · 7,677 accessesView PDFCite
