Research ArticleOpen accessEvery word in the titleHide Dehairing and Laundry Detergent Compatibility Testing of Thermostable and Solvents Tolerant Alkaline Protease from Hot Spring Isolate Bacillus cohniiU3Pravin R. Dudhgara, Bhavsar Sunil, Ghelani AnjanaIn the present study, alkaline protease producing thermophilic Bacillus cohniiU3 strain was isolation from Unnai hot spring, India. The maximum production of protease (344 U/mL) was reported after 72 h of inoculation at 50°C in shake flask culture using the gelatin casein medium. The protease was found to remain active up to 96 h and production was growth dependent. The … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 23 Jul 2015 · 7,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMOTIONS STUDY OF A SINGLE CYLINDER HIGH SPEED SPARK IGNITION LINIER ENGINE WITH SPRING SYSTEM AS RETURN CYCLEA. Z.M. Fathallah, Semin, I. M. Ariana, I. GeriantoA single cylinder two stroke spark ignition conventional engine have been modified to linier engine with spring mechanism. Before develop the design of linear engine is necessary to analysis of motion. Although principle of combustion process in combustion chamber is the same in fact the oscillation movement is different. Simulation technique has been adopted to study both linear and conventional … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 17 Jan 2014 · 7,179 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicrobial Consortia from Taptapani Hot Water Springs for Mining Effluent TreatmentPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The Km and Rmax … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,461 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDrawing Meshed One-Line Diagrams of Electric Power Systems using a Modified Controlled Spring Embedder Algorithm Enhanced with Geospatial DataAlexandre de Assis Mota, Lia Toledo Moreira MotaProblem statement: One-line diagrams are widely used in electrical power systems to provide a graphical view of state of the system and to assess its performance. Several methodologies and algorithms have been proposed to automatically draw the power system’s one-line diagram and provide satisfactory results for radial or small-size meshed networks. Nevertheless, actual power systems models are generally associated to … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 8,096 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Spring Design as Return Cycle of Two Stroke Spark Ignition Linear Engine on the Combustion Process and PerformanceA. Z.M. Fathallah, R. A. BakarProblem statements: The effects of optimization on spring design of the linear engine with spring mechanism in its performance and combustion process have been examined. However, at certain conditions the engine can not work properly as predicted. This can happen because displacement of engine stroke is depending on thrust forces of combustion process in cylinder of the engine. For that, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,512 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrediction Studies for the Performance of a Single Cylinder High Speed Spark Ignition Linier Engine with Spring Mechanism as Return CycleA.Z.M. Fathallah, R.A. BakarProblem statement: Most concepts of linear engines were constructed as opposed pistons with complicated control devise to drive the engines. The advantage of the engines was their high overall efficiency. Approach: Although the efficiency was higher than conventional engine, however, it did not be applied yet, because the design of these engines was not only difficult to fabricate, but also … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,302 accessesView PDFCite
