ON THE OSCILLATION OF SECOND-ORDER NONLINEAR DIFFERENTIAL EQUATIONS WITH DAMPING
(UNIV MISKOLC INST MATH, 2017)
In this paper, we are concerned with the oscillations in forced second order nonlinear differential equations with nonlinear damping terms. By using clasical variational principle and averaging technique, new oscillation ...
The effect of teachers' shared leadership perception on academic optimism and organizational citizenship behaviour: a Turkish case
(TAYLOR & FRANCIS LTD, 2017)
Purpose: The present study investigates the capability of high school teachers' shared leadership perception to predict the academic optimism and organizational citizenship levels. Research methods: The population of the ...
Behavior of Meromorphic Functions at the Boundary of the Unit Disc
(UNIV NIS, FAC SCI MATH, 2017)
In this paper, a boundary version of the Schwarz lemma for meromorphic functions is investigated. The modulus of the angular derivative of the meromorphic function I-n f(z) = 1/z + 2(n)c(0) + 3(n)c(1)z+4(n)c(2)z(2) +... ...
Non-modifiable factors predict discharge quality after robotic partial nephrectomy
(SPRINGER, 2017)
To identify predictors of poor discharge quality after robotic partial nephrectomy (RPN) at a large academic center. We queried our institutional RPN database for consecutive patients treated between 2011 and 2015. The ...
Experimental and computational study of the structure and spectroscopic properties of 1 ',3 '-Dihydrospiro[cyclohexane-1,2 '-[2H] imidazo[4,5-b]pyridine]
(ELSEVIER SCIENCE BV, 2016)
The optimized molecular geometry and vibrational frequencies of 1',3'-Dihydrospiro[cyclohexane-1,2'-[2H]imidazo[4,5-b]pyridine] were calculated using Hartree Fock (HF) and Density Functional Theory (DFT) methods. The ...
Experimental (XRD, IR and NMR) and theoretical investigations on 1-(2-nitrobenzoyl)3,5-bis(4-methoxyphenyl)-4,5-dihydro-1H-pyrazole
(ELSEVIER SCIENCE BV, 2016)
The pyrazole compound 1-(2-nitrobenzoyl)3,5-bis(4-methoxyphenyl)-4,5-dihydro-1H-pyrazole (I) has been synthesized and characterized by IR, NMR and X-ray diffraction methods. The compound crystallizes in the monoclinic space ...
Usefulness of the thrombolysis in myocardial infarction risk index in acute heart failure: a pilot study
(W B SAUNDERS CO-ELSEVIER INC, 2016)
Background: Risk stratification in acute heart failure (AHF) is vital for both physicians and paramedical personals. Thrombolysis in myocardial infarction (TIMI) risk index (TRI) and modified TRI (mTRI) are novel and simple ...
The structural, elastic, electronic and dynamical properties of chalcopyrite semiconductor BeGeAs2 from first-principles calculations
(SPRINGER, 2017)
First-principles calculations for the structural, elastic, electronic and vibrational properties of BeGeAs2 with chalcopyrite structure have been reported in the frame work of the density functional theory. The calculated ...
Effect of Heat Treatment on the Magnetic Properties of a CuMn Alloy
(SPRINGER, 2017)
In this paper, we reported the effect of heat treatment on the magnetic properties of Cu (75.8)-Mn (24.2) alloy (wt%) alloy. Magnetization measurements were performed by using a vibrating sample magnetometer (VSM) at 300 ...
