Application of Box-Behnken design and response surface methodology for modeling of some Turkish coals
(ELSEVIER SCI LTD, 2007)
The aim of our research was to apply Box-Behnken experimental design and response surface methodology for modeling of some Turkish coals. As a base for this study, standard Bond grindability tests were initially done and ...
EVALUATION OF GENOTOXIC EFFECTS OF ODIUM SULPHITE, POTASSIUM SULPHITE AND CALCIUM SULPHITE ON THE ROOT MERISTEM CELLS OF Allium cepa
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2009)
The effects of different treatments with food preservatives sodium sulphite (SS), potassium sulphite (PS) and calcium sulphite (CS) on the cytology, DNA content and interphase nuclear volume (INV) of A. cepa were investigated. ...
The dependence of the intersubband transitions in square and graded QWs on intense laser fields
(PERGAMON-ELSEVIER SCIENCE LTD, 2004)
The intersubband absorption in square and graded quantum wells under a laser field is calculated within the framework of the effective mass approximation. We conclude that, for quantum wells with different shapes, the laser ...
The prevalence of virchow-robin spaces in hippocampus in temporal lobe epilepsy
(UNIVERSITATSVERLAG ULM GMBH, 2005)
Aim: To determine the prevalence of Virchow-Robin spaces in hippocampus in temporal lobe epilepsy. Methods: Virchow-Robin spaces were evaluated on cranial magnetic resonance imaging of 46 patients with temporal lobe epilepsy ...
Reduced P-selectin in Hearts Pretreated with Fluvastatin: A Novel Benefit for Patients Undergoing Open Heart Surgery
(GEORG THIEME VERLAG KG, 2009)
Objective: P-selectin is an adhesion molecule that plays a role in the pathogenesis of atherosclerosis. The aim of this study was to assess whether or not the treatment with fluvastatin for 3 weeks preoperatively would ...
Atrial natriuretic peptide predicts impaired atrial remodeling and occurrence of late postoperative atrial fibrillation after surgery for symptomatic aortic stenosis
(KARGER, 2006)
Background. Aortic stenosis (AS) and atrial fibrillation (AF) are commonly encountered in clinical practice. Natriuretic peptides (NP) are endogenous cardiac hormones, which have been shown to increase in patients with ...
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 ...
