Thermomechanical and thermogravimetric analysis of blends of poly (vinyl chloride) (PVC) with maleic anhydride-allyl propionate copolymer
(ELSEVIER SCIENCE BV, 2004)
Binary blends of poly (vinyl chloride) (PVC) and the maleic anhydride-allyl propionate (MA-AP) copolymer have been prepared in tetrahydrofurane solution, aimed the improvement of the thermomechanical properties. The blends ...
Flow analysis in centrifugal compressor vaneless diffusers
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2008)
Flow computations have been performed in vaneless diffuser (diam, 1 m), in low speed backswept centrifugal compressor using finite volume method (FVM),coupled with Standard k-epsilon turbulent model by solving oil commercial ...
Immobilization of Saccharomyces cerevisiae on to radiation crosslinked HEMA/AAm hydrogels for production of ethyl alcohol
(ELSEVIER SCI LTD, 2002)
Radiation crosslinked 2-hydroxyethyl methacrylate/acrylamide (HEMA/AAm) copolymers prepared by gamma-irradiation were used in experiments on swelling, diffusion, immobilization of yeast cells (Saccharomyces cerevisiae) and ...
ICE FORMATION AROUND A HORIZONTAL TUBE IN A RECTANGULAR VESSEL
(TURKISH SOC THERMAL SCIENCES TECHNOLOGY, 2009)

A model for extended bench casting in dipping coal seam
(NATL INST SCIENCE COMMUNICATION, 2007)
This paper deals with extended bench casting with draglines in surface coalmines. A computer model, developed for panel design, covers three fundamental operating modes: i) level casting for flat-lying coal seam; ii) ...
Treatment of landfill leachate by using electro-Fenton method
(ELSEVIER SCIENCE BV, 2009)
In this study, the effects of various operating conditions such as treatment time, DC current, initial pH, initial H(2)O(2) concentration and distance between the electrodes on treatability of landfill leachate by using ...
Application of Box-Wilson experimental design method for the photodegradation of textile dyestuff with UV/H2O2 process
(ELSEVIER SCI LTD, 2004)
Photodegradation of textile dyestuffs Chrysophenine Yellow (DY12), Congo Red (DR28) and Remazol Black B (RB5) by the UV/H2O2 process was investigated in a laboratory scale photoreactor equipped with a 16-W low-pressure ...
MRSA genotypes in Turkey: Persistence over 10 years of a single clone of ST239
(W B SAUNDERS CO LTD, 2009)
Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of life-threatening human infections. The clinical impact of MRSA is mounting, not only due to the ever-increasing prevalence but also ...
Mechanisms and transition structures for conjugate and carbonyl addition of ammonia to three small alpha,beta-unsaturated carbonyl compounds. An ab initio molecular orbital study
(ELSEVIER SCIENCE BV, 2001)
Transition structures for the addition of ammonia to s-cis and s-trans acrolein, methyl vinyl ketone, and 2-butenal have been located with ab initio molecular orbital calculations. Optimization of the geometries of reactants, ...
