Solvent effects on dimeric self-association of 2-pyrrolidinone: An ab initio study
(KLUWER ACADEMIC PUBL, 2001)
Full geometry optimizations were carried out for 2-pyrrolidinone (2-Py) and its dimer structures at the DFT (B3LYP) and HF levels in the gas phase and in solution. Additionally, single-point MP2/6-31G** calculations were ...
A study on the relationship between critical surface tension of wetting and oil agglomeration recovery of calcite
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
In this study, it was investigated that the relationship between the critical surface tension of wetting of calcite and agglomeration recovery depending on pH and amount of collector (Na oleate). For this purpose, effects ...
A magnetic resonance imaging study of the adhesio interthalamica in epilepsy
(UNIVERSITATSVERLAG ULM GMBH, 2004)
Aims: The aim of the present study was to determine whether the absence of adhesio interthalamica is associated with epilepsy. Methods: Thirty-seven patients with epilepsy and 21 healthy volunteers were included in the ...
Interpenetrating polymeric network hydrogels for potential gastrointestinal drug release
(JOHN WILEY & SONS LTD, 2007)
New interpenetrating polymeric network (IPN) hydrogels based on chitosan (C), poly(N-vinyl pyrrolidone) (PVP) and poly(acrylic acid) (PAAc), crosslinked with glutaraldchyde (G) and N,N'-methylenebisacrylamide (MBA), were ...
Landslide susceptibility mapping using frequency ratio, logistic regression, artificial neural networks and their comparison: A case study from Kat landslides (Tokat-Turkey)
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The purpose of this study is to compare the landslide susceptibility mapping methods of frequency ratio (FR), logistic regression and artificial neural networks (ANN) applied in the Kat County (Tokat-Turkey). Digital ...
Differential effect of cold acclimation on blood composition in rats and hamsters
(SPRINGER HEIDELBERG, 2001)
Male rats and hamsters were exposed to a progressively lower air temperature and shorter photoperiod to simulate the onset of winter. Normothermic hamsters had a higher haematological oxygen carrying capacity (OCC) and ...
A study on spherical oil agglomeration of barite suspensions
(ELSEVIER SCIENCE BV, 2003)
In this study, the recovery of barite particles was investigated by using oil agglomeration. For this purpose, effects of operating parameters were investigated and also, zeta potential measurements and Fourier Transform ...
The effects of topically applied nitrofurazone and rifamycin on wound healing
(H M P COMMUNICATIONS, 2006)
Topical application of a combination of nitrofurazone and rifamycin in contaminated wounds is widely used in Turkey with considerable success. Although nitrofurazone is generally abandoned in European countries and the ...
Rho-kinase inhibitors Y-27632 and fasudil prevent agonist-induced vasospasm in human radial artery
(CANADIAN SCIENCE PUBLISHING, NRC RESEARCH PRESS, 2009)
Radial artery (RA) vasospasm remains a potential cause of early graft failure after coronary artery bypass graft surgery, despite pretreatment with alpha-adrenergic or calcium channel blockers. Our aim was to investigate ...
The effects of creatine long-term supplementation on muscle morphology and swimming performance in rats
(JOURNAL SPORTS SCIENCE & MEDICINE, 2009)
Creatine (Cr) has been shown to increase the total muscle mass. The purpose of this study was to investigate the effect of Cr supplementation on muscle morphology and swimming performance, using an animal model. Each rat ...
