Numerical simulation of the stalled flow within a vaned centrifugal pump
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2004)
The main goal of the present work is to analyse the numerical simulation of a centrifugal pump by solving Navier-Stokes equations, coupled with the 'standard k-epsilon' turbulence model. The pump consists of an impeller ...
Determination of relationships between thermal conductivity and material properties of rocks
(JOURNAL OF UNIV OF SCIENCE AND TECHNOLOGY BEIJING, 2004)
Energy transfer between the adjacent parts of rocks in underground mines is widely influenced by the thermal conductivity of rocks. The relationships between the thermal conductivity and some material properties of rocks ...

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 ...
Histological examination of ovarium development of shemaya Chalcalburnus chalcoides living in Lake Todurge (Sivas/Turkey)
(INST VERTEBRATE BIOLOGY AS CR, 2004)
The process of oogenesis of C. chalcoides living in Lake Todurge was histologically studied from monthly samples during April-November 2000. The process was divided into five stages (previtellogenic, cytoplasmic growth, ...
