In this paper we study the asymptotic behaviour via Γ-convergence of some integral functionals Fε which model some multi-dimensional structures and depend explicitly on the linearized strain tensor. The functionals Fε are defined in particular classes of functions with bounded deformation while the limit problem is set in the usual framework of Sobolev spaces or BD(Ω). We also construct an exam...

We study homogenization by Γ-convergence of functionals of type Z Ω W “ x ε ,∇φ(x) ” dx, where Ω ⊂ RN is a bounded open set, φ ∈ W 1,p(Ω; Rm) and p > 1, when the 1-periodic integrand W : RN ×Mm×N → [0, +∞] is not of p-polynomial growth. Our homogenization technique can be applied when m = N and W has a singular behavior of type W (x, ξ) → +∞ as detξ → 0. However, our technique is not consistent...

We study homogenization by Γ-convergence, with respect to the L1-strong convergence, of periodic multiple integrals in W 1,∞ when the integrand can take infinite values outside of a convex bounded open set of matrices.

in this paper, synthesized (raw) multi-walled carbon nanotube (rmwcnts) surfaces were modified with chitosan and β-cyclodextrin using chen’s soft cutting technique. raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (tem). the results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...

RATIONALE Endothelial cells (ECs) have distinct mechanotransduction mechanisms responding to laminar versus disturbed flow patterns. Endothelial dysfunction, affected by imposed flow, is one of the earliest events leading to atherogenesis. The involvement of γ/δ T lymphocytes in endothelial dysfunction under flow is largely unknown. OBJECTIVE To investigate whether shear stress regulates memb...

Ephedrine and pseudoephedrine can be used as precursors for the illicit synthesis of stimulant drugs, such methamphetamine methcathinone. For this reason, an enantioselective capillary electrokinetic chromatography method was developed separation ephedrine enantiomers. After testing two different charged or chargeable cyclodextrins (β-cyclodextrin sulphate carboxymethyl-β-cyclodextrin) a few mi...
