Effect of heating rate on thermoluminescence characteristics of Y2O3 nanoparticles
(Elsevier B.V., 2019)
The present paper reports the results of heating rate dependencies of thermoluminescence (TL)peaks observed for Y 2 O 3 nanoparticles in the below room temperature region. TL glow curve presented six peaks around 62.5, ...
The effects of systemic steroid therapy on macrophage migration inhibitory factor concentrations in patients with nasal polyps
(Cambridge University Press, 2018)
Objectives This study aimed to compare serum macrophage migration inhibitory factor concentrations before and after oral steroid therapy in nasal polyps patients, and determine whether there is a difference between ...
Temperature lag effect on TL glow peaks: Corrections on kinetic parameters
(Elsevier B.V., 2018)
Analyses on TL glow curves recorded with various heating rates for some ternary and quaternary crystals were accomplished using peak maximum temperatures (Tmax) which are experimentally obtained and corrected according to ...
The effect of austenitizing time on martensite morphologies and magnetic properties of martensite in Fe-24.5%Ni-4.5%Si alloy
(2007)
The effect of austenitizing time on the formation of martensite in Fe-24.5%Ni-4.5%Si alloy has been studied by means of transmission electronmicroscope (TEM), scanning electronmicroscope (SEM) and Mössbauer spectroscopy ...
Investigation of the time evolution of Lane-emden-type Kanai-caldirola oscillator
(2009)
In this study, we have investigated the time evolution of the first kind Lane-Emden-type Kanai-Caldirola oscillator. The total energy of the one dimensional classical harmonic oscillator with time-dependent mass is obtained. ...
Investigation of the time evolutions of some log-periodic oscillators
(2010)
We consider the time evolution of the one dimensional classical and quantum oscillator systems according to its mass and spring constant with fluctuating time. By using the SU(1,1) coherent states, the classical equations ...
Synthesis of pyrrolo-pyrrolo-pyrazines via the Pd/C-catalyzed cyclization of N-propargyl pyrrolinyl-pyrrole derivatives
(Elsevier Ltd, 2019)
A novel and efficient synthesis of N-substituted dipyrrolo[1,2-a:2',1'-c]pyrazine derivatives has been developed. The synthetic strategy relies on the synthesisof 4',5'-dihydro-1H,3'H-2,2'-bipyrrole, followed by the reaction ...
Synthesis of a bipyridine-derived achiral thiourea trifluoromethanesulfonic acid salt and its application as an additive in organocatalytic asymmetric reactions
(2013)
The host-guest complex of a proline-thiourea bipyridine trifluoromethanesulfonic acid salt can catalyze organocatalytic asymmetric reactions such as aldol, Michael, and Mannich in polar protic medium with high stereoselectivities. ...
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier B.V., 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
Seasonal variation and occurrence of algal turf community in Lake Ladik, Turkey
(2013)
The composition and seasonal variation of the algal turf of Lake Ladik were studied using samples collected from one station between June 2000 and May 2001. 50 tax^jfJriatoms were identified in the epiphyton. Navicula ...
