Abstract Lithospheric deformation is a fundamental process in plate tectonics. It is, therefore, critical to determine how the lithosphere responds geological loads better understand tectonic processes. The can be modelled as flexure of thin, elastic over long-term (> 10 5 yr) timescales. partial differential equation for an orthotropic used indirectly calculate theoretical admittance and co...

This works aims to build an equivalent model of multilayered structures with imperfect interfaces for vibro-acoustic modeling and characterization. To take into account imperfections, new interface conditions including constitutive equations, that describe the are implemented. Once displacement field is obtained, dispersion relation structure derived from model. The bending wavenumbers then use...

Abstract:   In this paper, the finite difference method (FDM) is applied to investigate the stability analysis and buckling load of columns with variable flexural rigidity, different boundary conditions and subjected to variable axial loads. Between various mathematical techniques adopted to solve the equilibrium equation, the finite difference method, especially in its explicit formulat...

BACKGROUND It is unclear whether eczema prevalence is truly increasing worldwide. OBJECTIVE We sought to investigate worldwide secular trends in childhood eczema. METHODS Children (n = 302,159) aged 13 to 14 years in 105 centers from 55 countries and children aged 6 to 7 years (n = 187,943) in 64 centers from 35 countries were surveyed from the same study centers taking part in Phase One an...

This research bridges the gap between quasi-static and high-strain-rate loading regimes in cross-laminated timber (CLT) by investigating two areas that have remained unstudied or elusive, i.e., rolling shear failure of CLT under impulsive, blast-like intermediate strain rates CLT. To study conditions would promote modes failure, a novel, highly adaptable center-point testing system methodology ...

background: flexural strength of prosthesis made with dental composite resin materials plays an important role in their survival. the aim of this study was investigating the effect of nanoclay fillers and poly (methyl methacrylate)-grafted (pmma-grafted) nanoclay fillers loading on the flexural strength of fiber-reinforced composites (frcs). materials and methods: standard frc bars (2 × 2 × 25 ...
