A COUPLED FIXED POINT RESULT IN PARTIALLY ORDERED PARTIAL METRIC SPACES THROUGH IMPLICIT FUNCTION
(HACETTEPE UNIV, FAC SCI, 2013)In this manuscript, we discuss the existence of coupled fixed points in the context of partially ordered metric spaces through implicit relations for mappings F:X x X -> X such that F has the mixed monotone property. Our ... -
In vivo evaluation of titanium-prepared platelet-rich fibrin (T-PRF): a new platelet concentrate
(CHURCHILL LIVINGSTONE, 2013)We have developed a new, titanium-prepared, platelet-rich fibrin (T-PRF) together with the protocol for forming it, which is based on the hypothesis that titanium tubes may be more effective at activating platelets than ... -
Enhancement of EFS-induced contractions, by agmatine, in guinea pig gallbladder smooth muscle strips
(SPRINGER TOKYO, 2005)Background. Electrical field stimulation of gallbladder muscle strips produces frequency-dependent contractions by activating cholinergic nerves. The cholinergic motor function of the gallbladder and enteric system is also ... -
Super water-retainer hydrogels: Crosslinked acrylamide/succinic acid copolymers
(SOC POLYMER SCIENCE JAPAN, 1997)Super water-retainer hydrogels in the rod form were prepared by copolymerization of acrylamide and succinic acid monomers with gamma radiation. Swelling took place in water at 25 degrees C and was followed by weighing. The ... -
DFT study on metal-mediated uracil base pair complexes
(ELSEVIER SCIENCE BV, 2017)The most stable of metal-mediated uracil base pair complexes were determined. Method was used density functional theory, B3LYP. The calculations of systems containing C, H, N, O were described by 6-311++G(d,p) and cc-PVTZ ... -
Tunable long-wavelength broad band asymmetric quantum well infrared photodetector
(IOP PUBLISHING LTD, 2007)We present a theoretical investigation of a GaAs/AlGaAs infrared detector consisting of three asymmetric quantum wells. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 8.2 mu m, 9.5 mu ... -
Factors Affecting Complication Rates of Percutaneous Nephrolithotomy in Children: Results of a Multi-Institutional Retrospective Analysis by the Turkish Pediatric Urology Society
(ELSEVIER SCIENCE INC, 2014)Purpose: We assessed factors affecting complication rates of percutaneous nephrolithotomy in children. Materials and Methods: We retrospectively evaluated data on 1,205 renal units in 1,157 children treated with percutaneous ... -
CO-releasing properties and anticancer activities of manganese complexes with imidazole/benzimidazole ligands
(TAYLOR & FRANCIS LTD, 2016)Carbon monoxide (CO) is an important signaling molecule which plays significant roles in the pathogenesis of cancer. CO is produced by enzymatic degradation of heme in mammals. Heme oxygenase 1 (HO-1) catalyzes the breakdown ... -
