(BIOMED CENTRAL LTD, 2012)Q fever is a worldwide zoonotic infection that caused by Coxiella burnetii, a strict intracellular bacterium. It may be manifested by some of the autoimmune events and is classified into acute and chronic forms. The most ... -
Polyelectrolyte CASA hydrogels for uptake of uranyl ions from aqueous solutions
(JOHN WILEY & SONS INC, 2007)In this study, uranyl ion adsorption from aqueous solutions has been investigated by chemically crosslinked acrylamide/sodium acrylate (CASA) hydrogels. Adsorption studies were investigated by the spectroscopic method. ... -
Efficiency determinations of the worldwide railway companies via DEA and contributions of the outputs to the efficiency and TFP by panel regression
(SPRINGER, 2015)This study attempts to obtain efficiency scores of thirty-one railway companies operating worldwide by using data envelopment analysis. To assess the data covering a term from 2000 to 2009, we use CCR and BCC methods. ... -
Response of AGATA segmented HPGe detectors to gamma rays up to 15.1 MeV
(ELSEVIER SCIENCE BV, 2013)The response of AGATA segmented HPGe detectors to gamma rays in the energy range 2-15 MeV was measured. The 15.1 MeV gamma rays were produced using the reaction d(B-11,n gamma)C-12 at E-beam=19.1 MeV, while gamma rays ... -
Statin pretreatment and risk of in-hospital atrial fibrillation among patients undergoing cardiac surgery: a collaborative meta-analysis of 11 randomized controlled trials
(OXFORD UNIV PRESS, 2015)Aims Statin pretreatment in patients undergoing cardiac surgery is understood to prevent postoperative atrial fibrillation (AF). However, this is based on observational and limited randomized trial evidence, resulting in ... -
The effect of percutaneous mitral balloon valvuloplasty on left atrial systolic functions
(TERMEDIA PUBLISHING HOUSE LTD, 2011)Background: Conventional echocardiographic methods have already shown that successful mitral balloon valvuloplasty (MBV) can effectively increase left atrial (LA) functions. Aim: To evaluate LA functions after MBV using ... -

(GALENOS YAYINCILIK, 2010)Aim: The aim of this study is to determine the portion of children vaccinated against HBV and immunized to HBV after vaccination program was started in Turkey, to detect infected children with HBV or carriers, and to show ... -
The association of biomass fuel combustion on pulmonary function tests in the adult population of Mid-Anatolia
(BIRKHAUSER VERLAG AG, 2004)Objectives: To assess the association of biomass as domestic energy source on respiratory function in rural areas of Mid-Anatolia in Turkey where biomass use is frequent. Methods: In a cross-sectional study, pulmonary ... -
Surface roughness of new microhybrid resin-based composites
(AMER DENTAL ASSOC, 2005)Background. Rough, poorly polished resin-based composite (RBC) surfaces contribute to staining, plaque accumulation, gingival irritation and recurrent caries. Proper finishing and polishing enhance both the esthetics and ... -
Biological denitrification of drinking water in a slow sand filter
(ELSEVIER SCIENCE BV, 2007)Biological removal of nitrate from drinking water was studied in a slow sand filter. Optimum carbon to nitrogen ratio (C/N) was found to be 1.8 when using acetic acid in batch tests. The filtration rates impact on NO3-N ... -
