Concerning the solvent effect in the tautomerism of uracil, 5-fluorouracil, and thymine by density-functional theory and ab initio calculations
(SPRINGER, 2001)
The tautomerism of uracil, 5-fluorouracil, and thymine has been investigated in the gas phase and in solution. Electron correlation effects were included in ab initio computations at the MP2 level, and DFT calculations ...
K-Ar age determination, whole-rock and oxygen isotope geochemistry of the post-collisional Bizmisen and Calti plutons, SW Erzincan, eastern Central Anatolia, Turkey
(WILEY-BLACKWELL, 2005)
Post-collisional granitoid plutons intrude obducted Neo-Tethyan ophiolitic rocks in central and eastern Central Anatolia. The Bizmisen and Calti plutons and the ophiolitic rocks that they intrude are overlain by fossiliferous ...
Metabolic syndrome negatively impacts early patency of saphenous vein grafts
(LIPPINCOTT WILLIAMS & WILKINS, 2006)
Background Coronary artery bypass grafting has been performed for a long period utilizing saphenous vein grafts, the fate of which might be crucial to prognosis following the operation. Metabolic syndrome, on the other ...
Combination of the particle size distributions of some industrial minerals measured by Andreasen pipette and sieving techniques
(WILEY-V C H VERLAG GMBH, 2007)
It is known that size of the individual particles is the predominant factor affecting the behavior of particulate materials, and that the size effects become increasingly important as the particles become finer. In this ...
Tortuosity of coronary arteries: an indicator for impaired left ventricular relaxation?
(SPRINGER, 2007)
Objective To investigate the relationship between coronary tortuosity and impaired left ventricular relaxation. Methods One hundred and four subjects who underwent coronary angiography were included in the study. Left ...
Adsorption of BSA onto radiation-crosslinked poly(AAm/HPMA/MA) terpolymers
(SPRINGER-VERLAG, 2003)
The terpolymeric poly(acrylaDaide/2-hydroxypropylmethacrylate/maleic acid) (AAm/ BPMA/MA) hydrogels in the rod form have been prepared by gamma-radiation of quaternary mixtures of acrylamide, 2-hydroxy propylmethacrylate, ...
Structural and optical properties of zinc nitride films prepared by pulsed filtered cathodic vacuum arc deposition
(IOP PUBLISHING LTD, 2007)
Polycrystalline zinc nitridefilms are deposited on Corning 7059 glass substrates by pulsedfiltered cathodic vacuum arc deposition (PFCVAD). The crystallographic structure is studied by means of x-ray diffraction. These ...
Intersubband transitions in an asymmetric double quantum well
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2007)
The intersubband optical absorption in an asymmetric double quantum well for different barrier widths and the right well widths are theoretically calculated within the framework of effective mass approximation. The results ...
Conductive potassium feldspar/polyaniline composites prepared by in situ chemical polymerization
(ELSEVIER SCIENCE SA, 2007)
K-feldspar particles using potassium dichromate in an acidic aqueous medium. The effects of K-feldspar particle size, aniline concentration and temperature upon the PAn amount in the composite and the electrical surface ...
Smoking among nurses in Turkey: Comparison with other countries
(I C D D R B-CENTRE HEALTH POPULATION RESEARCH, 2007)
The purpose of this study was to obtain baseline information on smoking among nurses. An attempt was made to contact, in person, all 301 nurses working for the university hospital in Sivas, Turkey, and when contacted they ...
