Effects of applied electric and magnetic fields on the nonlinear optical properties of asymmetric GaAs/Ga1-xAlxAs double inverse parabolic quantum well
(ELSEVIER SCIENCE BV, 2015)
The combined effects of electric and magnetic fields on the optical absorption coefficients and refractive index changes related to the intersubband transitions within the conduction band of asymmetric GaAs/Ga1-xAlxAs ...
Some results on ideals of semiprime rings with multiplicative generalized derivations
(TAYLOR & FRANCIS INC, 2018)
Let R be a semiprime ring and I a nonzero ideal of R. A map F:RR is called a multiplicative generalized derivation if there exists a map d:RR such that F(xy)=F(x)y+xd(y), for all x,yR. In the present paper, we shall prove ...
Determination of Trace Inorganic Mercury Species in Water Samples by Cloud Point Extraction and UV-Vis Spectrophotometry
(AOAC INT, 2014)
A new micelle-mediated extraction method was developed for preconcentration of ultratrace Hg(II) ions prior to spectrophotometric determination. 2-(2'-Thiazolylazo)-p-cresol (TAC) and Ponpe 7.5 were used as the chelating ...
Synthesis, Molecular Modelling and Antibacterial Activity Against Helicobacter pylori of Novel Diflunisal Derivatives as Urease Enzyme Inhibitors
(BENTHAM SCIENCE PUBL LTD, 2019)
Background: The main factor for the prolongation of the ulcer treatment in the gastrointestinal system would be Helicobacter pylori infection, which can possibly lead to gastrointestinal cancer. Triple therapy is the ...
Determination of trace uranyl ions in aquatic medium by a useful and simple method
(SPRINGER, 2014)
Determination of trace uranyl ions was performed by using mixed micellar system and spectrophotometric determination. The method is based on cloud point extraction of uranyl ions after formation of an ion-association complex ...
Sexuality Assessment Knowledge, Attitude, and Skill of Nursing Students: An Experimental Study with Control Group
(WILEY, 2017)
PURPOSE: The purpose of this study was to determine sexuality assessment knowledge, attitude, and skill of student nurses before and after sexuality training. METHODS: This study was conducted experimentally in a model ...
PEPPSI-type 2-methyl-2-propenyl-functionalized N-heterocyclic carbene-palladium complexes: Synthesis, structural characterization and catalytic activity on Suzuki-Miyaura reaction
(ELSEVIER SCIENCE BV, 2019)
N-Heterocyclic carbenes (NHCs) have been known to be efficient ligands for the Suzuki-Miyaura cross-coupling. In this work, four novel 2-methyl-2-propenyl substituted N-heterocyclic carbene ligands (1a-d) were synthesized ...
A Study of New benzo[d]thiazol Derivatives as Corrosion Inhibitors for Steel AISI 1035 in Acidic
(UNIV MOHAMMED PREMIER OUJDA, 2019)
Benzo[d]thiazol-2-ol (BAT), benzo[d]thiazol-2-amine (4-BAT) and benzo[d]thiazol-2-thiol (2-BAT) were prepared and evaluated as corrosion inhibitors for AISI 1035 steel in 1 M HCl. It is found that 4-BAT functions as more ...
Effect of Alkyl Chain Length on Adsorption Behavior and Corrosion Inhibition of Imidazoline Inhibitors
(JIHAD DANESHGAHI, 2018)
Inhibition performances of imidazoline derivatives with different alkyl chain length for carbon steel in H2S acid solutions has been studied by polarization curves, AC impedance measurements, current transient, Atomic Force ...
The effects of the composition of growth medium and fermentation conditions on the production of lipase by R. delemar
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2011)
Lipases (triacylglycerol hydrolases) are hydrolytic enzymes that can catalyze the hydrolysis of the ester bond of long-chain acylglycerols at the oil-water interface. The present study investigated the effects of inducers, ...
