Geological, mineralogical and geochemical characteristics of zeolite deposits associated with borates in the Bigadic, Emet and Kirka Neogene lacustrine basins, western Turkey
(SPRINGER VERLAG, 1996)
The Bigadic, Emet and Kirka lacustrine basins of western Turkey may be considered as Tibet-type graben structures that were developed during the Miocene within the Izmir-Ankara suture zone complex. The volcanic-sedimentary ...
In vitro swelling studies and preliminary biocompatibility evaluation of acrylamide-based hydrogels
(ELSEVIER SCI LTD, 1996)
In this in vitro study, the biocompatibility of acrylamide-based hydrogels such as acrylamide/crotonic and acrylamide/itaconic acid, prepared by using gamma-rays, has been investigated against some biochemical parameters ...
Shear flocculation of chromite fines in sodium oleate solutions
(ELSEVIER SCIENCE BV, 1996)
In this study, chromite fines were aggregated by stirring after the particle surfaces were made hydrophobic with sodium oleate. The effects of pH, sodium oleate concentration, stirrer speed and flocculation time were ...
Behaviors of acrylamide/maleic acid hydrogels in uptake of some cationic dyes from aqueous solutions
(MARCEL DEKKER INC, 1996)
Acrylamide/maleic acid (AAm/MA) hydrogels prepared by irradiating with gamma-radiation were used in experiments on swelling, diffusion, and uptake of some cationic dyes such as basic red 9 (BR-9), basic green 4 (BG-4), ...
Effect of deferoxamine and sympathectomy on vasospasm following subarachnoid hemorrhage
(KARGER, 1996)
We examined the effects of subarachnoid hemorrhage (SAH) and treatment with deferoxamine (DFO) or sympathectomy on vascular smooth muscle function, as well as the underlying mechanisms involved, by recording the responses ...
A simple method for calculating the force fields of M(CO)(5)L and square pyramidal M(CO)(5) complexes
(PERGAMON-ELSEVIER SCIENCE LTD, 1996)
A relationship between the interaction constant of cis-COeq-COax and the observed (CO)-C-12-O-16 stretching frequencies has been derived to solve the secular equations for M(CO5)L and M(CO)(5) complexes which belong to ...
Investigation of acid sites on V2O5/TiO2(A) catalysts by FTIR with adsorption of pyridine
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)
The V2O5/TiO2(A) catalysts were prepared by the grafting and their Bronsted and Lewis acid sites were investigated with pyridine adsorption by using FTIR Spectroscopy. The results obtained showed that monolayer or less ...
The effects of hemodialysis on duodenal and gastric mucosal changes in uremic patients
(DUSTRI-VERLAG DR KARL FEISTLE, 1996)
From March 1992 to July 1992 30 uremic patients (15 dialysed, 15 non-dialysed) and 15 non-uremic patients who had dyspeptic complaints were compared in terms of gastric and duodenal diseases. Gastritis and duodenitis graded ...
A study on the adsorption of some cationic dyes onto acrylamide/itaconic acid hydrogels
(SPRINGER VERLAG, 1996)
Acrylamide/itaconic acid (AAm/IA) hydrogels prepared by irradiating with gamma radiation were used in experiments on the adsorption of some cationic dyes such as basic red 9 (BR 9), basic green 4 (BG 4), cresyl violet (CV), ...
Boron-nitride-coated nuclear fuels
(AMER NUCLEAR SOCIETY, 1996)
Pure urania- and urania-gadolinia-containing fuel pellets were coated with boron nitride (BN) to improve the physical and neutronic properties of the fuel. The BN coating seems to have a technological advantage over ...
