Singular Perturbation Models in Phase Transitions for Second Order Materials

A variational model proposed in the physics literature to describe the onset of pattern formation in two-component bilayer membranes and amphiphilic monolayers leads to the analysis of a Ginzburg-Landau type energy, precisely, u 7→ ∫ Ω [ W (u)− q |∇u| + ∣∣∇2u∣∣2 ] dx. When the stiffness coefficient −q is negative, one expects curvature instabilities of the membrane and, in turn, these instabili...

Me 354, Mechanics of Materials Laboratory Stress Concentrations

i) Install the un-notched beam (see Fig. 1) in the four-point flexure loading fixture ii) Attach the load pan (Note: The combined pan/fixture mass is ~0.980 kg) iii) Apply two10-kg masses one at a time to the load pan. iv) With the polarizer and analyzer crossed (dark field), focus the camera, and record the image using the thermal printer v) Determine the maximum fringe orders at the top and b...

Modified Laplace Decomposition Method for Singular IVPs in the second-Order Ordinary Differential Equations

  In this paper, we use modified Laplace decomposition method to solving initial value problems (IVP) of the second order ordinary differential equations. Theproposed method can be applied to linear and nonlinearproblems    

Second Surgery in Insular Low-Grade Gliomas

BACKGROUND Given the technical difficulties, a limited number of works have been published on insular gliomas surgery and risk factors for tumor recurrence (TR) are poorly documented. OBJECTIVE The aim of the study was to determine TR in adult patients with initial diagnosis of insular Low-Grade Gliomas (LGGs) that subsequently underwent second surgery. METHODS A consecutive series of 53 pa...
