Blow-up of solutions for a logarithmic quasilinear hyperbolic equation with delay term
(Univ. Prithtines, 2021)In this work, we deal with a logarithmic quasilinear hyperbolic equation with delay term. Under suitable conditions, we get blow up of solutions in a finite time. Our results are more general than the earlier results. -
CO2 sensing behavior of vertically aligned Si Nanowire/ZnO structures

Darboux transformation for the hirota equation
(B Verkin Institutation Low Temperature Physics & Engineering Nas Ukraine, 2022)The Hirota equation is an integrable higher order nonlinear Schrodinger type equation which describes the propagation of ultrashort light pulses in optical fibers. We present a standard Darboux transformation for the Hirota ... -
Developing a scale for attitudes toward the environment
(Türk Eğitim Derneği, 2005)Abstract:The purpose of this study is to develop a valid and reliable Likert- type scale to measure the attitudes of pre-service teachers toward the environment. A 30-item draft attitude scale was applied to 366 pre-service ... -
The effect of tin doping level on the physical properties and photocatalytic degradation of cadmium oxide nanostructured film
(Elsevier, 2021)Pure and tin (Sn) doped CdO films were deposited onto soda-lime glass via ultrasonic spray pyrolysis (USP) method with Sn concentrations of 1, 2 and 3%. The effect of doping level on the structural, morphological and optical ... -
Existence and blow up of solutions for a strongly damped Petrovsky equation with variable-exponent nonlinearities
(Texas State University, 2021)In this article, we consider a nonlinear plate (or beam) Petrovsky equation with strong damping and source terms with variable exponents. By using the Banach contraction mapping principle we obtain local weak solutions, ... -
Existence, blow up and growth of solutions for a coupled quasi-linear viscoelastic Petrovsky equations with degenerate damping terms
(Analytic Publ. Co., 2021)We consider a quasilinear coupled system of two viscoelastic equations with degenerate damping and source terms under Dirichlet boundary condition. We obtain the global existence, blow up and exponential growth of solutions ... -
Global existence and decay of solutions for a higher-order Kirchhoff-type systems with logarithmic nonlinearities
(Natl Inquiry Services Centre Pty Ltd., 2022)In this paper, we aim to understand the characteristics of dynamical behaviour for a higher order Kirchhoff type systems with logarithmic nonlinearities. Based on the potential well method, the main ingredient of this study ... -
Global existence and decay of solutions for a system of viscoelastic wave equations of Kirchhoff type with logarithmic nonlinearity
(Wiley, 2022)This work deals with a system of Kirchhoff-type equations with viscoelastic term and logarithmic nonlinearity. First, we proved the global existence by combining the potential well method with Faedo-Galerkin's procedure. ... -
Global existence of solutions for a coupled viscoelastic plate equation with degenerate damping terms
(Tbilisi Centre Mathematical Science, 2021)We consider a coupled viscoelastic plate nonlinear equations with degenerate damping terms on a bounded domain in R-n. We establish the global existence results under different conditions. -
