A microscopic heterogeneous system under random influence is considered. The randomness enters the system at physical boundary of small scale obstacles as well as at the interior of the physical medium. This system is modeled by a stochastic partial differential equation defined on a domain perforated with small holes (obstacles or heterogeneities), together with random dynamical boundary condi...

We consider the Neumann boundary value problem for harmonic maps in an annular domain with a large number of small holes. On the boundary of the domain the degree condition is prescribed. We obtain an effective (homogenized) anisotropic nonlinear problem. We also discuss applications of these results to homogenized description of superconducting composites and superfluidity.

Abstract The presence of prestrain can have a tremendous effect on the mechanical behavior slender structures. Prestrained elastic plates show spontaneous bending in equilibrium—a property that makes such objects relevant for fabrication active and functional materials. In this paper we study microheterogeneous, prestrained feature non-flat equilibrium shapes. Our goal is to understand relation...

introduction: this study was carried out to determine elements (li, na, k, mg, ca, ba, b, al, si, v, cr, mn, fe, co, ni, cu, zn, se, ag and p) in the suaeda vermiculata (s. vermiculata) and suaeda aegyptiaca (s. aegyptiaca) in three different regions of southern iran using inductively coupled plasma optical emission spectrometry (icp-oes) after microwave-assisted acid digestion. materials and m...

The aim of this study was preparation of a standard extract from the leaves of Artemisia absinthium in order to add into a suspention formula as a laxative agent for use in animal husbandry. As approved by the commission E, the Artemisia absinthium preparations are used internally for loss of appetite, dyspeptic, liver, and gallbladder complaints. A. absinthium is commonly used in food industry...

'101 The prostaglandins are potent autacoids which are widely distributed in mammalian tissues [I] including the central nervous system of various species [2-43. Although tissue stores are quite small, prostaglandins (PG's) are rapidly synthesized and released in association with peripheral nerve stimulation [S]. Several groups of workers have reported that PG's and PG-like substances are relea...
