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, ...
PERMUTING TRI-DERIVATIONS IN LATTICES
(NATL INQUIRY SERVICES CENTRE PTY LTD, 2009)
The aim of this paper is to introduce the notion of permuting tri-derivations in lattices and to study some properties of permuting tri-derivations.
The rodent fauna from the Adapazari pull-apart basin (NW Anatolia): its bearings on the age of the North Anatolian fault
(EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2001)
To the east of the Sea of Marmara, the North Anatolian fault (NAF) branches into two strands, namely the northern and the southern strands. The Adapazari pull-apart basin is located in the overlapping zone of the Dokurcun ...
Molecular modeling study on the relative stabilities of the flotation products for arsenic-containing minerals: dixanthogens and arsenic(III) xanthates
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)
The interactions of As(III) ion with C2H5OCS2- and C2H5SCS2-, known as the most popular collector ions, were studied by density functional theory (DFT) at the B3LYP/6-31G** level in connection with the arsenic-containing ...
Rare earth double sulfates from pre-concentrated bastnasite
(ELSEVIER SCIENCE BV, 2008)
A mixture of rare earth double sulfates was produced from a Turkish bastnasite-containing pre-concentrate (low grade concentrate) by sulfuric acid baking, subsequent water leaching and precipitation with sodium sulfate. ...
Pullback mode dragline stripping in dipping coal seam
(IMPERIAL COLLEGE PRESS, 2002)
This study presents the results of a computer-based model developed for analysing the pit geometry formed when a dragline operates in pullback mode. Basically, three spoiling procedures are modelled for a flat or an inclined ...
Effect of ketanserin administration on intraocular pressure
(KARGER, 2001)
Purpose: We evaluated the effect of oral single-dose (20 mg) ketanserin on intraocular pressure (IOP) in normotensive and hypertensive eyes. Methods: This study included 15 healthy volunteers and 16 patients with ocular ...
