Hydrophobicity of chalcopyrite with dithiophosphate and dithiophosphinate in electrochemically controlled condition
(ELSEVIER SCIENCE BV, 2004)
The degree of hydrophobicity of chalcopyrite was determined by contact angle measurements on polished chalcopyrite surface in electrochemically controlled conditions. Results have shown that the increase in solution pH ...
Synthesis, characterization and evaluation of IPN hydrogels for antibiotic release
(TAYLOR & FRANCIS INC, 2004)
We prepared new ternary interpenetrating polymeric networks (IPN) systems containing chitosan, poly(N-vinylpyrrolidone) and poly(acrylamide) polymers. IPNs were synthesized by radical polymerization of acrylamide monomers ...
The effects of Niguldipine pretreatment on cerebral vasospasm after subarachnoid haemorrhage in rabbits
(JOHN WILEY & SONS LTD, 2004)
Several different mechanisms contribute to the pathogenesis of cerebral vasospasm after subarachnoid haemorrhage. Whatever these mechanisms are, the vessel contraction is ultimately induced by an increase of free intracellular ...
Investigation of relationship between critical surface tension of wetting and oil agglomeration recovery of barite
(ELSEVIER SCIENCE BV, 2004)
In this study, relationship between the critical surface tension of wetting of barite and agglomeration recovery and also zeta potential depending on pH and amount of collector (Na-oleate) was investigated. For this purpose, ...
Effect of peritonitis on gallbladder smooth muscle contractility in guinea pigs
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
Background. The mechanisms involved in the impaired gallbladder contractile response in peritonitis are unknown. The aim of this study was to determine the effect of peritonitis on the contraction and relaxation responses ...
The association of biomass fuel combustion on pulmonary function tests in the adult population of Mid-Anatolia
(BIRKHAUSER VERLAG AG, 2004)
Objectives: To assess the association of biomass as domestic energy source on respiratory function in rural areas of Mid-Anatolia in Turkey where biomass use is frequent. Methods: In a cross-sectional study, pulmonary ...
A basal chalcidoid (Insecta : Hymenoptera) from the earliest Cretaceous or latest Jurassic of Mongolia
(BRILL ACADEMIC PUBLISHERS, 2004)
Khutelchalcis gobiensis gen. et sp. n. (Khutelchalcididae fam. n.), based on a tiny impression fossil collected from the lowermost Cretaceous or uppermost Jurassic deposits of Khutel-Khara in East Mongolia, was studied ...
Prevalence of atopy in rheumatoid arthritis in Sivas, Turkey. A prospective clinical study
(SPRINGER HEIDELBERG, 2004)
Assumed mutual antagonism of T-helper cell (Th)1 and Th2 diseases suggests that the prevalence of atopy should be decreased in rheumatoid arthritis (RA). We tried to determine that prevalence. Sixty-two patients with RA ...
Ultramafic-rock-hosted vein sepiolite occurrences in the Ankara ophiolitic melange, Central Anatolia, Turkey
(CLAY MINERALS SOC, 2004)
A 2 m thick brecciated zone containing magnesian minerals is present at the contact of tectonites and cumulates. Tectonites below this zone comprise serpentinized orthopyroxenite and serpentinite. An alteration zone with ...
