Multi-objective optimization of some process parameters of a multi-gravity separator for chromite concentration
(ELSEVIER SCIENCE BV, 2008)
The multi-gravity separator (MGS) is one of the fine particle mineral concentration machines based on gravity separation. Concentration performance, indicators such as grade and recovery, depends on appropriate selection ...
Sulfotransferase 1A1 (SULT1A1) polymorphism and susceptibility to primary brain tumors
(SPRINGER, 2008)
Purpose Sulfotransferase 1A1 is a member of sulfotransferase family that plays an important role in the biotransformation of numerous carcinogenic and mutagenic compounds through sulfation. The present study has investigated ...
Combination of different size distributions for mineral particles by applying experimentally determined apparent mean shape factor
(TAYLOR & FRANCIS INC, 2008)
As is well known, the behavior of systems of fine particles is strongly dependent on the size of the individual particles, and the size effects become increasingly important as the particles become progressively smaller. ...
Analysis of vascular endothelial growth factor gene 936 C/T polymorphism in patients with familial Mediterranean fever
(WILEY, 2008)
Vascular endothelial growth factor (VEGF) is a cytokine that promotes endothelial cell proliferation, leucocyte chemotaxis and expression of adhesion molecules and is a major mediator of vascular permeability. It has been ...
Effects of Light Curing Modes and Resin Composites on Temperature Rise under Human Dentin: An in vitro Study
(JAPANESE SOC DENTAL MATERIALS DEVICES, 2008)
The influence of three curing modes of a high-powered LED curing unit on temperature rise under 2-mm-thick dentin was investigated during the polymerization of resin composite samples of Admira, Filtek P60. Premise, Tetric ...
Endothelial Nitric Oxide Synthase Gene [G894T] polymorphism as a possible risk factor in aneurysmal subarachnoid haemorrhage
(SPRINGER WIEN, 2008)
Background. The exact aetiology, growth and rupture of intracranial aneurysms is unclear. In this study we investigated a possible association between intracranial aneurysm rupture and polymorphism of the endothelial nitric ...
Fluid inclusion and stable isotope characteristics of the Arapucandere Pb-Zn-Cu deposits, northwest Turkey
(BELLWETHER PUBL LTD, 2008)
The Arapucandere Pb-Zn-Cu ores are typical examples of vein-type lead-zinc deposits in the Biga Peninsula. Permian-Triassic metamorphic, Triassic metabasic and metabasic rocks, Oligocene-Miocene granitoids, Miocene volcanic ...
Composition and in vitro antimicrobial activity of Populus buds and poplar-type propolis
(SPRINGER, 2008)
The antibacterial activity of propolis has been widely investigated. Since reports dealing with antimicrobial activity of the origin of propolis are not available, this study was carried out aiming to analyse the in vitro ...
Alterations in spontaneous contractions of rat ileum and jejunum after peritonitis
(ELSEVIER SCIENCE BV, 2008)
The aim of this study was to investigate the effects of peritonitis on spontaneous contractions of ileum and jejunum smooth muscles isolated from rats. Peritonitis was induced by cecal ligation and puncture in 8 rats. ...
Flash pyrolysis of Silopi asphaltite in a free-fall reactor under vacuum
(ELSEVIER SCIENCE BV, 2008)
Flash pyrolysis experiments on asphaltite samples were performed in a free-fall reactor under vacuum to determine the effects of pyrolysis temperature, feed rate and particle size. Maximum liquid yield of 13 wt.% was ...
