utopia has, for four centuries, accompanied that hope of progress and that striving for betterment. it now straggles against a widespread sense that this has been an illusion, or an impossible dream. the utopian idea can never entirely disappear, but utopia as a form of the social imagination has clearly weakened. if it cannot instill its vision in the public consciousness, the consequences...
this study investigates the problem of translating religious allusions in persian literature, namely the ones borrowed from quranic verses and hadiths. the purpose of this study is to shed light on how different translators dealt with such a task and also to provide guidelines for translators in coping with religious allusions.
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...
abstract: the present study is about prophet ishmael, some parts of his life; his personality in the quran and the bible; and the comparison of the content of these two religious books. compilation of the study has been done with a new perspective and new presentation approach. since prophets have been human beings’ role model and their life has been a perfect example for humanity in all ages,...
abstract: the equal channel angular rolling (ecar) is one of the severe plastic deformation processes, which can develop a shear deformation into a sheet metal. in this process, internal stresses are created due to the different strain levels experienced in different locations at the same time. the incremental hole drilling method is an effective technique for the evaluation of the through-thic...
In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
