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.

background: the alteration of th1 and th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a th2 immune response. objective: to examine the different levels of il-4 and il-10 (th2 cytokines), and il-2 and interferon-γ (ifn-γ) (th1 cytokines) in malignant and non-malignant pleural effusions. method: the cytokine levels in pleural fl...

The entrance of Cd (II) to aqueous environments causes a major problem to human health. The current article examines the efficiency of TiO2 and γ-Al2O3 nanoparticles in Cd (II) removal from aqueous medium as influenced by different chemical factors, such as pH, initial concentration, background electrolyte, and ionic strength, in accordance with standard experimental methods. It conducts Batch ...

Objective(s): Multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE), are regarded as autoimmune diseases of the central nervous system (CNS).  The CNS, testes, and eyes are immune privileged sites.  It was initially presumed that ocular involvement in EAE and infertility in MS are neural-mediated.  However, inflammatory molecules...

Background: Cytotoxic CD8+ T cells, as essential parts of the adaptive immune system, play pivotal roles in anti-tumor immune responses. It is well documented that cytokine expression profiles and activation status of these cells during anti-tumor immune responses affect the outcome of host-tumor interaction. Objective: To investigate the percentages of CD8+ lymphocytes and their subsets in...

objective(s): β-thalassemia is one of the most common genetic disorders in the world. as one of the promising treatment strategies, fetal hemoglobin (hb f) can be induced. the present study was an attempt to reactivate the γ-globin gene by introducing a gene construct containing klf1 binding sites to the k562 cell line. materials and methods: a plasmid containing a 192 bp sequence with two repe...
