15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولAn insight into effect of surface functional groups on reactivity of Sphalerite (110) surface with Xanthate collector: a DFT study
The reactivity of the protonated and hydroxylated sphalerite (1 1 0) surface with xanthate was simulated using the density functional theory (DFT). The difference between the energy of the lowest unoccupied molecular orbital of the sphalerite surface and the energy of the highest occupied molecular orbital of xanthate ( was used to compare the reaction capability of xanthate with fresh and fun...
متن کاملEffect of Ultrasonic Pre-Treatment and Aeration on Flotation Separation of Chalcopyrite from Pyrite
In this paper, the effect of ultrasonic pre-treatment and aeration on the flotation separation of chalcopyrite from pyrite was investigated at different amounts of potassium ethyl xanthate (KEX), as a collector, and pH values. Artificially-mixed samples of chalcopyrite and pyrite were subjected to flotation studies to understand the effect of aeration with or without ultrasonic tre...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
