calculate some thermodynamic properties of molten polymers including specific volume and isothermal compressibility (S.M. Hoseini, Physical Chemistry & Electrochemistry, 2 (2014) 56-65). This work extended that EOS to predict the volumetric properties of some molten ethylene copolymers including ethylene/1-octene, ethylene/1-butene (xethylene equal to 0.8543 and 0.563), ethylene/propene. The ab...

one of the great challenges in the processing of materials using equal channel angular pressing (ecap) is the high forming forces required to produce large shear deformation in the material. researchers show that the friction forces between the die and the sample constitute a great part of the total forming forces. recently, ultrasonic vibrations are successfully implemented into the ecap proce...

abstract  the discovery of cave paintings made by upper paleolithic artists in western europe was an astonishing find about the human past. they were discovered in the late nineteenth century and involved the scientific community with the new subject under the title of prehistory art. since the discovery of the astonishing relics, several theories proposed by different specialists with special ...

today, most of the big cities or metropolises around the world have been encountering with the problem of informal habitation. the present study, thus, tries to focus on the role of endogenous development in such type of habitation process. for that matter, the paper takes into account architectural programming and urbanism as its theoretical framework because the endogenous development is rela...

almost a century and a half ago, the name or concept of archeology was not commonly known in iran. as a branch of human sciences, archeology emerged in iran as a consequence of the political-economic influence of the west, and reached its present condition after many vicissitudes; presently, therefore, archeology has penetrated into diverse levels of the iranian society. this, however, is a ver...
