The predictive value of heart rate turbulence for ventricular systolic dysfunction and prognosis in the peri-infarction period
(2007)Objectives: This study was conducted to investigate the relationship between heart rate turbulence (HRT) and acute left ventricular systolic dysfunction due to ST-segment elevation acute myocardial infarction (STEMI). Study ... -
Removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions by adsorption onto natural bentonite
(2007)In this study, the removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions using the adsorption process onto natural bentonite has been investigated as a function of initial metal concentration, pH and temperature. ... -
Diagenesis and very low-grade metamorphism of the Antalya unit: Mineralogical evidence of Triassic rifting, Alanya-Gazipaşa, central Taurus belt, Turkey
(2005)The Paleozoic-Lower Mesozoic formations of the Antalya Unit in southern Turkey comprise diagenetic sediments, shale, mudstone, shale, siltstone, sandstone and scarce spiculite, together with very low-grade metamorphic ... -
The Influence of Preparation Methods on the Swelling and Network Properties of Acrylamide Hydrogels with Crosslinkers
(Marcel Dekker Inc., 2004)Using different types and concentrations of crosslinkers, acrylamide (AAm) hydrogels have been prepared with chemical initiation and gamma irradiation techniques. The effects of the preparation method, crosslinkers type ... -
Palaeomagnetic study of crustal deformation across an intracontinental transform: The North Anatolian Fault Zone in Northern Turkey
(1996)Eocene volcanic rocks spanning the North Anatolian Fault Zone in north central Turkey have a common reversed polarity and appear to record a short term volcanic episode useful for identifying subsequent tectonic rotations. ... -
On trace of symmetric of bi-gamma-derivations in gamma-near-rings
(2007)Let M be a 2-torsion free 3-prime left ?-near-ring with multiplicative center C. For x ? M, let C(x) be the centralizer of x in M. The aim of this paper is to study the trace of symmetric bi-?-derivations (also symmetric ... -
Blast design and optimization studies for a celestite open-pit mine in Turkey
(Imperial College Press, 1996)In this paper, the results of blast optimization studies for rock units of celestite open pit mine located in Sivas-Ula region have been presented and discussed. An extensive two years research programme was carried out ... -
Study of quantitative sleeping electroencephalography (EEG) in bruxism cases
(2005)Bruxism is a behavioral disorder characterized by daytime or nighttime tooth grinding. Many etiological factors have been suggested for sleep bruxism. Among these, elevated mental and physical alertness have been proposed ... -
Rapid diagnosis of catheter related sepsis in hemodialysis patients
(2001)Purpose: To distinguish between infected and non-infected Central Venous Catheters (CVCs) applied to hemodialysis patients without having to wait bacterial cultures, we evaluated the importance of sera C-Reactive Protein ... -
Numerical and experimental study of flow and heat transfer around a tube in cross-flow at low Reynolds number
(Elsevier Science Inc, New York, NY, United States, 1998)A numerical and experimental study of the laminar flow and heat transfer characteristics of a cylinder in cross-flow is presented. The computational technique used is a stream function-vorticity formulation of the laminar ... -
One-stage combined surgery with or without preoperative traction for developmental dislocation of the hip in older children.
(2006)PURPOSE. To compare one-stage combined surgery with and without preoperative traction, in older children with developmental dislocation of the hip (DDH). METHODS. Records of 9 children who underwent combined surgery for ... -
Impacts of human activities on groundwater quality of an alluvial aquifer: A case study of the eskişehir plain, Turkey
(Springer New York, 1997)Groundwater in an alluvial aquifer in the Eski?cehir plain, Turkey, has been polluted by means of municipal and industrial wastewaters and agricultural activities. This pollution is of concern because a large amount of ... -
Karyological observations on the field cricket, gryllus campestris l. (gryllidae, orthoptera)
(2003)The diploid chromosome number of males of the Field Cricket, Gryllus campestris, from Sivas was found to be 2 n = 29, with 6 pairs metacentric, 3 pairs submetacentric, 5 pairs subacrocentric autosomes, and 1 X metacentric. ... -
The temperature dependence of the electronic structure of Si ?-doped GaAs
(2002)We investigated theoretically the change of electronic properties of Si ?-doped GaAs layer as a function of temperature. We studied the influence of temperature on the donor concentration for a nonuniform distribution, ... -
Recent temporal change in the stress state and modern stress field along the North Anatolian Fault zone (Turkey)
(Oxford University Press, 1997)The North Anatolian Fault (NAF) is a dextral strike-slip fault which runs about 1400 km from east to west, from the Karliova triple junction to the Aegean domain. It was active during the Plio-Quaternary as a consequence ... -
