Multicriteria choice of ore transport system for an underground mine: application of PROMETHEE methods
(SOUTH AFRICAN INST MINING METALLURGY, 2004)
The aim of this paper is to demonstrate the implementation of multicriteria analysis in selection of the most suitable underground ore transport system for a chromite mine in Turkey. The related problem includes five ...
Layered feedforward neural network is relevant to empirical physical formula construction: A theoretical analysis and some simulation results
(ELSEVIER SCIENCE BV, 2005)
We theoretically establish that, contrary to superficial observation, constructing an empirical physical formula (or physical law interchangeably) to explain the physical phenomenon is inherently full with several serious ...
Investigation of the relaxant effects of pancuronium, rocuronium, vecuronium and mivacurium on rat thoracic aorta
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Background and objective Pancuronium, vecuronium, mivacurium and rocuronium are nondepolarizing neuromuscular blocking agents, which are competitive antagonists against acetylcholine at nicotinic receptors, and considered ...
Conjunctival impression cytology in pseudoexfoliative glaucoma and pseudoexfoliation syndrome
(WILEY, 2006)
In this study, ocular surface changes and tear film functions in patients with pseudoexfoliative glaucoma (PEXG) and pseudoexfoliation (PEX) syndrome were evaluated. This study is a randomized, double-blind and prospective ...
Effects of ceftriaxone sodium on in vitro gallbladder contractility in guinea pigs
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)
Background/Purpose. It has been reported that ceftriaxone may induce the formation of gallstones. Changes of gallbladder motility may play a role in this phenomenon. The present study was designed to analyze the gallbladder ...
Genetic polymorphisms of GSTs and their association with primary brain tumor incidence
(ELSEVIER SCIENCE INC, 2005)
Glutathione S-transferases GSTM1, GSTT1, and GSTP1 are phase II biotransformation enzymes that function on detoxification of a wide range of exogenous agents including carcinogens. It has been shown that genetic variations ...
Coronary collateral circulation: Any effect on P-wave dispersion?
(SAGE PUBLICATIONS INC, 2008)
Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between ...
Shallow-water foraminiferal assemblages and microfacies of the Danian-Lutetian sequences in the Bolu region (Northwestern Turkey)
(PLEIADES PUBLISHING INC, 2005)
The Paleocene and Eocene sediments of Bolu region were studied with respect to benthic foraminiferal stratigraphy and microfacies. In general, the Paleocene and Maastrichtian successions have conform contacts except for a ...
The evolution of travertine masses in the Sivas area (Central Turkey) and their relationships to active tectonics
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008)
Sicak Cermik, Delikkaya and Sarikaya are important travertine fields with active hot springs located 31 km west of Sivas. Based on their morphology, most of the travertines are classified as fissure-ridge travertines. ...
On Lie ideals with generalized derivations
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2006)
Let R be a prime ring with characteristic different from 2, let U be a nonzero Lie ideal of R, and let f be a generalized derivation associated with d. We prove the following results: (i) If a is an element of R and [a, f ...
