Affine Osserman connections and their Riemann extensions
Garcia-Rio, E; Kupeli, DN; Vazquez-Abal, ME; Vazquez-Lorenzo, R (Elsevier BV, 1999-09-01)
Osserman property is studied for affine torsion-free connections with special attention to the 2-dimensional case. As an application, examples of nonsymmetric and even not locally homogeneous Osserman pseudo-Riemannian met...
Thermally stimulated current in layered semiconductor TlInS2 with incommensurate phase
Ozdemir, S; Suleymanov, RA; Civan, E; Firat, T (1996-05-01)
The thermally stimulated current (TSC) is studied in the temperature range between the commensurate phase (CP) and incommensurate phase (ICP) in layered semiconductor TIInS2. It is shown that the successive thermocyclings ...
A NEW CRYOSTAT AND TEMPERATURE CONTROLLER FOR TSC MEASUREMENTS
OZDEMIR, S; DEMIRBAS, A; OZAVCI, E (IOP Publishing, 1993-03-01)
A linear temperature controller and a cryostat have been developed to measure thermally stimulated current (TSC) in CdS, a-Si:H and CdTe in order to determine the trapping characteristic. In this paper, the temperature con...
Present and future prospects of the use of information technology in schools in Turkey
Ozar, M; Askar, P (Springer Science and Business Media LLC, 1997-01-01)
TEMPERATURE-DEPENDENT ELECTRICAL CHARACTERISTICS OF AL-SIOX-PSI SOLAR-CELLS
OZDEMIR, S; ALTINDAL, S (Elsevier BV, 1994-02-01)
Current-voltage (I-V) and capacitance-voltage (C-V) characteristics of Al-SiOx-pSi metal-insulator-semiconductor (MIS) solar cells were measured in the temperature range between 295 K and 375 K. The semilogarithmic plot of...
Designing a magic flask: a new activity for teaching nature of science in both formal and informal learning environments
Eren-Sisman, Ece N.; KÖSEOĞLU, FİTNAT (2019-12-17)
The magic flask, which is a kind of black box activity, builds an environment for science teachers to discuss nature of science in a formal or/and informal learning environment in the context of the history of science thro...
Use of graping calculators in high school mathematics-1: Samples of the students' views as a case study
Ersoy, Yasar (2007-12-01)
Background/Problem Statement: While the use of information and communication technologies (ICT) in general computers and advanced calculators in particular has been increased in teaching mathematics in developed countries,...
ELASTIC-CONSTANTS OF UVITE - TEMPERATURE-DEPENDENCE
TATLI, A (Elsevier BV, 1988-01-01)
The temperature dependence of the single-crystal elastic constants of uvite—CaMg3(MgAl5)B3Si6(O,OH)30 (OH, F)—was measured between 80 and 300 K by the ultrasonic pulse-echo-overlap method. The temperature dependence was li...
Spinodal instabilities in nuclear matter in a stochastic relativistic mean-field approach
Ayik, S.; Yılmaz Tüzün, Özgül; Er, N.; Gokalp, A.; Ring, P. (American Physical Society (APS), 2009-09-01)
Spinodal instabilities and early growth of baryon density fluctuations in symmetric nuclear matter are investigated in the basis of the stochastic extension of the relativistic mean-field approach in the semiclassical appr...
Quantal effects on spinodal instabilities in charge asymmetric nuclear matter
Ayik, S.; Er, N.; Yılmaz Tüzün, Özgül; Gokalp, A. (Elsevier BV, 2008-11-01)
Quantal effects on growth of spinodal instabilities in charge asymmetric nuclear matter are investigated in the framework of a stochastic mean field approach. Due to quantal effects, in both symmetric and asymmetric matter...
