Research ArticleOpen accessIn the abstractBACTERIAL ISOLATES OF MARINE COAST AS COMMERCIAL PRODUCER OF PROTEASES. Das, I. Mukherjee, M. Sudarshan et al.The objective of this work was to explore and exploit the extracellular protease secreting marine microbial biodiversity of the eastern coastal region of India. Culture dependent method was applied for isolation of microbes from the marine coast of West Bengal (Digha and Mandarmani) and Andhra Pradesh (Vizag) in India. Six protease secreting isolates were screened using casein hydrolysing property as … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 8 Aug 2012 · 8,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractManaging Process Hazards in Lab-Scale Pilot Plant for Safe OperationHanida Abdul Aziz, Azmi Mohd Shariff, Mohd Rafizie RoslanIn spite of the OSHA Laboratory and Hazards Communication Standards, incidents which result in injuries and property loss continue to occur in the research and teaching locations. Application of Process Hazard Analysis (PHA) of OSHA Process Safety Management (PSM) to laboratory pilot plant operations has the potential to further reduce risk associated with this location. However, a major challenge is … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 26 May 2012 · 9,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation of Amylolytic Bacteria from Viscera of Labeo rohita (Ham.) and Optimization of Alpha Amylase ExtractionDebabrat Baishya, Hridip Kumar SarmaProblem statement: Fish is largely consumed in the north-eastern part of India resulting in the generation of huge amount of fish viscera in the market places. These waste generated is not properly managed for disposal. Under such circumstances it is necessary to properly utilize this waste regenerating the possibility of environment friendly disposal. Besides, industrially and commercially useful biological products … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractMinimum and Complete Fluidization Velocity for Sand-Palm Shell Mixtures, Part I: Fluidization Behavior and Characteristic VelocitiesV. S. Chok, A. Gorin, H. B. ChuaProblem statement: Palm shell on its original state cannot be fluidized solely. However, mixing palm shell with a second fluidizable material can facilitate proper fluidization. Approach: The minimum and complete fluidization velocity (Umf and Ucf) for sand/palm shell binary mixtures had been studied in a partitioned reactor known as Compartmented Fluidized Bed Gasifier (CFBG). The pilot scale reactor ID is … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpiral Wound Reverse Osmosis Membranes for the Recovery of Phenol Compounds-Experimental and Parameter Estimation StudiesG. Srinivasan, S. Sundaramoorthy, D.V.R. MurthyProblem statement: Reverse osmosis is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. The removal of an organic compound, namely phenol, using a polyamide membrane was investigated in this study. Waste water containing phenol present a serious environmental problem and increasing attention is being given … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne can Achieve the Nuclear Fission Reaction of Lithium by Accelerated Hydrogen Nuclei or NeutronsRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe idea circulated among physicists that in the upper area of the physical elements the fission reaction can be obtained and in the lower one the fusion reaction occurs. In the presented paper we want to impose another rule, namely the obtaining in the lower part of the physical elements of the fission and fusion nuclear reactions, with the obvious … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 7 Sep 2021 · 9,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractGEOPHYSICAL AND LABORATORY STUDIES OF THE SPREAD AND QUALITY OF THE ODUKPANI LIMESTONE DEPOSITT. E. Chidomerem, A. E. Akpan, I. O. AkpanThe Odukpani limestone deposit has been investigated using geophysical and laboratory techniques with the aim of generating information on its spread and quality. Information generated from the analyses of twenty-six Vertical Electrical Soundings (VES) and core drilling data were used in the study. The VES data were acquired in both grid and random patterns in the immediate area of the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 20 Jun 2014 · 7,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty and its Impact on the Quality of MeasurementMartin Halaj, Adel Elahdi M. YahyaThe imposition of practice, the current world, the laboratory measurement, calibration should be approved by points of credit to national or international and should be compatible with the requirements specification (ISO 17025) for the adoption of efficient laboratories. Those requirements were included the testing process or scale limits to doubt that mentioned in the measurement certificate, which recognizes the customer … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Jul 2012 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
