The phase behavior of strongly segregated AB diblock copolymer and selective C homopolymer blends is examined theoretically using a combination of strong stretching theory (SST) and self-consistent field theory (SCFT). The C-homopolymer is immiscible with the B-blocks but strongly attractive with the A-blocks. The effect of homopolymer content on the order-order phase transitions is analyzed. I...

This paper aims to first present a review of studies on numerical modeling and seismic response analysis above ground steel liquid storage tanks. On that basis, procedure for estimating dynamic parameters associated with simplified models anchored unanchored conditions together calculation methods responses damage states tanks are presented. In which, the nonlinear behavior bottom plate in case...

A number of heating sources are available for minimally invasive thermal therapy of tumours. The purpose of this work was to compare, theoretically, the heating characteristics of interstitial microwave, laser and ultrasound sources in three tissue sites: breast, brain and liver. Using a numerical method, the heating patterns, temperature profiles and expected volumes of thermal damage were cal...

PURPOSE To explore the associations between anisometropia and spherical ametropia, astigmatism, age, and sex. METHOD Associations between the prevalence and magnitude of anisometropia with age, sex, spherical power, and cylindrical power, were assessed in a group of 90,884 subjects attending optometry practices in the United Kingdom. Logistic regression models were used to assess the independ...

Point vortex and vortex blob computations are used to investigate the evolution of the planar and the axisymmetric vortex sheet which initially induce ow past a cylinder and past a sphere respectively. In both cases the sheet develops a singularity at two points in the symmetry plane at a nite time. It rolls up at these points forming a vortex pair in the planar case and a vortex ring in the ax...

Starting from a mean-field description for a dispersion of highly charged spherical or (parallel) rodlike colloids, we introduce the simplification of a homogeneous background to include the contribution of other polyions to the static field created by a tagged polyion. The charge of this background is self-consistently renormalized to coincide with the polyion effective charge, the latter quan...

Abstract. Computational models of mantle convection must accurately represent curved boundaries and the associated boundary conditions a 3-D spherical shell, bounded by Earth's surface core–mantle boundary. This is also true for comparable in simplified 2-D cylindrical geometry. It fundamental importance that codes underlying these are carefully verified prior to their application geodynamical ...
