In this paper, preparation of SrAl2O4:Eu,Dy luminescent pigment has been investigated. Coprecipitation as a low cost and facile method was selected. X-ray diffraction patterns indicated the formation of SrAl2O4:Eu,Dy phase through calcinations process above 800 °C. Moreover, a few amount of silica caused the structural transformation to alumina silicate phase. Transparent glaze which consist of...
The world pottery history is replete with different shapes and designs as well as various technical ways of firing and decorating. The purpose of this study is to evaluate the effect of this reducing firing on different color oxides in two alkaline-boron and lead-boron glaze bases. The question raised in this study is that what effects do the different bases of lead-boron and alkali-boron glaze...
luster glaze technique is, in fact, using luster glaze in painting and decorating on the glaze which is heated in reduced kiln as a third step. luster glaze is formation of a very thin layer of silver and copper nanoparticles with a metallic luster in different color range formed on the surface of the glaze during the third stage of heating in reduction condition. luster glazed art’s peak, in i...

in this article, we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators. considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...
abstract today, pottery in shahreza of isfahan is a valuable arts with its up and downs which has stabilized its place among iranian pottery centers. the investigation of contemporary pottery in the course of history shows that iranian potters have used predecessors' experiences, as well as remained professions of pottery art such as soheili, bahari and fakhar, and tried to promote qual...

the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
