as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...
the present study aimed to investigate the possible effects of focused highlighted error feedback on grammatical accuracy of writing among iranian intermediate efl learners. after selecting 52 homogenous participants from among 70 university students attending azad university of rasht and randomly dividing them into two intact groups of 26 students, the researcher exposed the participants of th...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Abstract A DNS approach for Eulerian-Eulerian dispersed particles simulation is presented in which a stress term corresponding to the uncorrelated motion of dispersed particles is identified. Two models for this stress terms are proposed. The first model uses an isentropic approximation that relates the local amount of uncorrelated particle kinetic energy to the particle number density. The sec...
Granular flow in a rotating drum is studied by experiments and by Computation Fluid Dynamics (CFD) simulations. The particulate phase is modelled based on the Continuum Eulerian Approach (CEA) in the simulation. The particulate phase CEA prediction using the common Gidaspow granular kinetic viscosity or the Syamlal-O’brien granular kinetic viscosity fails to predict the measured dynamic angle o...
A Lagrangian-Eulerian methodology is developed for the numerical simulation of a gas-solid reactive flow. The SO2-NOx Adsorption Process (SNAP) is taken as a test case. A three-dimensional time dependent simulation is performed. A notional particle based Monte-Carlo algorithm is used to solve the transported composition Probability Density Function (PDF) equations to determine the gas phase com...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
