poly(vinylidene fluoride) (pvdf) fibers with two molecular weights were prepared via electrospinning process. in this process, the concentration of spinning depended drastically on the gelation process. also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (sena). proof of this incompatibility was explained by the properties of pvdf and its...

the paper tries to investigate the question whether photography could be considered as a source of knowledge since the medium has expanded our knowledge about the world, enriching our visual unconscious as benjamin puts it. highlighting the objective, mechanical formation of photographic image -not being shared by other forms of visual representation including painting and drawing-anumber of ph...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...

Abstract The Fairlie-Gumbel-Morgenstern (FGM) family has been investigated in detail for various continuous marginals such as Cauchy, normal, exponential, gamma, Weibull, lognormal and others. It has been a popular model for the bivariate distribution with mild dependence. However, bivariate FGM’s with continuous marginals on a bounded support discussed in the literature are only those with uni...
