Failure and flow development of a collapse induced complex landslide: the 2005 Kuzulu (Koyulhisar, Turkey) landslide hazard
(SPRINGER, 2006)
Koyulhisar located in a slope of hilly region and constructed in the side of a mountain along the North Anatolian Fault Zone is frequently subject to landslides. A catastrophic landslide occurred on the morning of 17 March ...
Density of impurity states of hydrogenic impurities in an inverse parabolic quantum well under the magnetic field
(ELSEVIER SCIENCE BV, 2007)
We investigated the effects of the magnetic field on the density of impurity states in a GaAs/GaAlAs inverse parabolic quantum well (lPQW) for different Al concentrations at the well center. The calculations were performed ...
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 magnetic and electric fields on the hydrogenic impurity in an ellipsoidal parabolic quantum dot
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2008)
The binding energy of a hydrogen-like impurity in an ellipsoidal parabolic quantum dot under the magnetic and electric fields have been discussed by using the effective mass approximation and the variational method. We ...
A giant coronary sinus mimicking descending aorta
(ACTA CARDIOLOGICA, 2008)
A 58-year-old male patient was admitted to the emergency service with dyspnoea. The patient underwent several laboratory and imaging tests including echocardiography and a diagnosis of descending aortic aneurysm was ...
Comparison of myocardial performance index versus ratio of isovolumic contraction time/ejection time in left ventricular systolic dysfunction
(SPRINGER, 2007)
Myocardial performance index (MPI) has been regarded as an important parameter in the evaluation of ventricular systolic function in congestive heart failure. This study was designed to investigate the relationship between ...
Numerical investigation of fouling on cross-flow heat exchanger tubes with conjugated heat transfer approach
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Although fouling on heat exchanger tubes is extensively investigated, due to the lack of energy resources, the effects of fouling on heat exchangers is still an important area of study and gaining more and more attention ...
