Research ArticleOpen accessIn the abstractStatistical Analysis of Geothermal Data of an Oil Field, in Parts of Niger Delta, NigeriaEmujakporue Godwin Omokenu, Leonard I. NwosuGeothermal gradient and heat flow were computed from bottom hole temperatures in an oil field in Niger Delta, Nigeria. The statistical analysis of computed geothermal data was carried out. The computed geothermal gradient vary from 17.3±0.14 to 24.33±0.70°C/Km with an average of 22.24±0.57°C/km. The heat flow ranges from 38.06±0.31 to 56.39±2.41 mWm-2 with an average of 50.15±1.25 mWm-2. The computed … …Current Research in Geoscience, Vol. 6, Issue 2 · 26 Sep 2016 · 7,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractGetting an Alternative Pitch Binder by Thermal Dissolution of CoalPeter Nikolayevich Kuznetsov, Elena Nikolaevna Marakushina, Anastasia Valerievna Kazbanova et al.The process of thermal dissolution of medium metamorphosed coals in anthracene oil to produce an alternative pitch binder was studied. The process was carried out at temperatures from 350 to 400°C and pressure not higher than 2.5 MPa, without the use of hydrogen and catalysts. It was determined that during thermal dissolution hard coal of gaseous-fat grade demonstrated a higher … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 4 Jan 2016 · 8,138 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 abstractComposition Dependent Structural and Thermal Properties of SM2O3 Doped Zinc Fluoroborate GlassesSudha D. Kamath, Akshatha Wagh, M.P. AjithkumarGlasses based on Sm3+ doped zinc fluoroborate have been synthesized and characterized. Formation of glass has been investigated in the 30 ZnF2-20 TeO2-(50-x) B2O3-x Sm2O3 matrix. Fast quenching is required to prevent melt crystallization and adequate heat treatment to diminish thermal stress, which results in an efficient amorphous material.

Research ArticleOpen accessIn the abstractDESIGN OF CANDIDA ANTARCTICA LIPASE B THERMOSTABILITY IMPROVEMENT BY INTRODUCING EXTRA DISULFIDE BOND INTO THE ENZYMEUsman Sumo Friend Tambunan, Ahmad Randy, Arli Aditya ParikesitCandida Antarctica Lipase B (CALB) is extensively studied in enzymatic production of biodiesel, pharmaceutical products, detergents and other chemicals. One drawback of using CALB is its relatively low optimum temperature at 313 K (40°C). The objective of this research is to design CALB mutant with improved thermostability by introducing extra disulfide bond. Molecular dynamic simulation was conducted to get better … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 18 Apr 2014 · 9,492 accessesView PDFCite
