a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...

In this paper, the propagation of electromagnetic waves through an infinite slab of uni- or bi- axial chiral medium is analytically formulated for an arbitrary incidence using 4×4 matrix method. In this powerful method, a state vector differential equation is extracted whose solution is given in terms of a transition matrix relating the tangential components of electric and magnetic fields at t...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

Topological analysis of the electronic charge density is introduced as a new tool for studying the electronic properties of the materials. In this method, the eigen values of the Hessian matrix of the electronic charge density as an scalar field are used to estimate the strength of the atomic bonds. We employ this method to study the half-metallic phase transition of MnAs in zinc blende structu...

  A second-order approximation to the Faddeev-Watson-Lovelace treatment of the rearrangement channel is used in a three-body scattering cross sections. In this formalism, the Three-body wave function is expressed by three coupled integral equations, the Faddeev equations, which contian the two-body (off-shell) transition amplitudes, and proved the uniqueness of their solutions. This amplitude c...

1 Ways to Describe a Stochastic Process We will use the biased coin example to illustrate three ways with which we can describe a stochastic process, a Markov Chain (MC) in particular. Probabilistic Random variable X represents the outcome of the experiment where we toss a specific coin once. There is 0.55 probability for the result to be heads (H) and 0.45 to be tails (T). X i = H with probabi...

kefiran is an exopolysaccharide produced by microorganisms present in the kefir grains that has several health promoting properties. in this research, physico-mechanical and thermal characteristics of nanocomposite film composed of kefiran-montmorillonite (mmt; 1, 3 and 5% w/w) were studied. results showed that the thickness and the tensile strength of the films increased by increasing the nano...

The object of this research is the investigation of carbon nanotube (CNT) distribution effect on electrical conductivity of polymer-CNT composite as dosimetry response of this system. Thus, electrical conductivity of this composite was simulated for aligned, homogenous, and agglomerated distributions in 2D, and 3D situations. The results of simulation were compared and validated by experimental...
