Opto-Thermal Properties of Fibres using Digital Holographic Interferometry
A hot stage attached to the phase shifting digital holographic interferometry (DHI) is used to study the effects of temperature on the optical properties of basalt fibres. The phase shifting Mach-Zehnder interferometer is used to obtain five phase-shifted holograms, in which the phase difference between two successive holograms is π/2. These holograms are numerically reconstructed using the con...
متن کاملThermal Oxidation of Polypropylene and Modified Polypropylene – Structure Effects
Ageing and stabilization polymers is a major part of materials science. Aging of polymers defined as a set of chemical and physical transformations, leads to the loss of their set the desired properties. The main role in these transformations belong to chemical processes of degradation and crosslinking of macromolecules. Processes decomposition and structuring polymer conjugates include radical...
متن کاملThe Impact of MnO, Li2O, ZnO and TiO2 on Mold Powders Viscosity Using Hot Stage Microscope Analysis
The aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel mold powders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samples containing such compositions as MnO, Fe2O3, Li2O, TiO2 and ZnO, as well as another fluorine-free sample containing a combination of Fe2O3 and TiO2, were prepared in this resea...

15 صفحه اولfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
