Research ArticleOpen accessIn the abstractEffect of Sulfonated Acetone Formaldehyde (SAF) on the Firing Resistance and Aggressive Attach of SRC-SF Composite Cement PastesRanda M. Osman, S. Al-MasryThis work aimed to study the effect of the dosage of laboratory synthesized Sulfonated Acetone Formaldehyde (SAF) on the physic-mechanical characteristics and durability of SF-SRC cement pastes immersed in 4% MgCl2 or 4% MgSO4 solutions or at elevated temperatures up to 800°C. The compressive strength of thermally treatment cement pastes with 1.5% SAF increases up to 600°C, then decreases up … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 22 Jun 2015 · 7,137 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
Research ArticleOpen accessIn the abstractINVESTIGATION STUDIES ON SUB-COOLING OF CRYOGENIC LIQUIDS USING HELIUM INJECTION METHODT. Ramesh, K. ThyagarajanIn cryogenic propellants, the sub-cooling of cryogenic propellants contained in tanks is an important and effective method for bringing down the lift-off mass of launch vehicle and thus the performance of the rocket engine is greatly improved. This study presents the technical and experimental studies conducted on cryogenic liquids such as Liquid Oxygen, Liquid Nitrogen and Liquid Hydrogen using helium … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 6,801 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE PROPERTIES OF NUCLEAR MATTERKhaled Hassaneen, Hesham MansourThe microscopic and bulk properties of nuclear matter at zero and finite temperatures are studied in the frame of the Brueckner theory. The results for the symmetry energy are also obtained using different potentials. The calculations are based on realistic nucleon-nucleon interactions which reproduce the nucleon-nucleon phase shifts. These microscopic approaches are supplemented by a density-dependent contact interaction to achieve … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 7,230 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Silver Vine (Actinidia Polygama Maxim, Family Actinidiaceae) as an Enrichment Aid for Felines: Issues and ProspectsCharles I. Abramson, Angela Lay, Timothy J. Bowser, Christopher A. VarnonProblem statement: This study highlights the potential of using silver vine as an enrichment additive for felines. Approach: A literature review was conducted on the use of silver vine since 1973. The articles were categorized into studies concerned with behavior, biological effects, beneficial uses, plant and chemical studies. Results: We found surprisingly few studies that utilized silver vine. There were … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 10 Mar 2012 · 18,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Eco friendly Refrigerants Usage in Air-ConditionerC. Chinnaraj, R. Vijayan, P. GovindarajanProblem statement: There are two types of global warming contributions through refrigeration and air conditioning systems. The first one is the Direct Global Warming Potential (DGWP) due to the emission of refrigerants and their interaction with heat radiation. The second one is the Indirect Global Warming Potential (IDGWP) due to the emission of Carbon Dioxide (CO2) by consuming the energy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 27 Dec 2011 · 8,462 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures. It was the catalyst of choice in the gas masks for respiratory protection in mines, aircrafts, military, spatial laboratories. Approach: The efficiency of hopcalite catalyst depends on its surface parameters. Its surface characteristics can be influenced from the chosen way of the … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Dynamics Simulation of DENV RNA-Dependent RNA-Polymerase with Potential Inhibitor of Disulfide Cyclic PeptideUsman Sumo Friend Tambunan, Raima Syahidah Noors, Arli Aditya Parikesit et al.Problem statement: Our researches have proposed two ligands of disulfide cyclic polypeptide, which are CDEEC and CDGSC as potential inhibitor of DENV RNA-dependent RNApolymerase by molecular docking. Approach: Methodological approach was conducted to determine the best ligand to act as inhibitor. Molecular docking simulation was conducted without a solvent in which enzyme was made rigid and ligand was left free … …OnLine Journal of Biological Sciences, Vol. 11, Issue 2 · 30 Sep 2011 · 8,441 accessesView PDFCite
