The primary aim of this paper is to define new concepts, A homogenous system difference equations called -semi order if there exists a non-zero matrix

purpose: to compare keratocyte density in stromal layers of the cornea in keratoconus, post-lasik keratectasia, lasik without keratectasia, and normal corneas by confocal scan. methods: thirty-one unscarred corneas from 22 patients with keratoconus, 24 clear corneas from 17 cases with post-lasik keratectasia, 12 corneas from 7 lasik cases without keratectasia, and 26 corneas from 13 normal subj...

in this paper, an analytical solution for computing the linear plastic stresses and critical temperature and pressure in a fgm hollow cylinder under the internal pressure and temperature is developed. it has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the fgm material according to a power law relationship. the poisson's...

amidoalkyl-2-naphthols as synthetic intermediates play an important role in medicinal chemistry due to their remarkable biological and many pharmacological properties. owing to the versatile biological activities, industrial and synthetic applications of these compounds, introduction of an alternative methodology is urgent in synthetic organic chemistry. low yield and harsh reaction conditions ...

The goal of this study is to examine the impact remittance inflow on inflation using System Generalized Method Moments (SGMM) and Dumitrescu-Hurlin Granger causality approach in countries from Central Eastern Europe over period 1994 2019. As levels economic financial development vary considerably across these some them are member states European Union (EU), we split into two more homogenous gro...
