We present the first nanoscale investigation of silica glaze. High resolution transmission electron microscopy of a rock coating from the Ashikule Basin, Tibetan Plateau, reveals the presence of spheroids composed predominantly of silicon and oxygen with diameters ranging from 20 nm to 70 nm. While silica glaze spheroids co-exist with manganese-rich rock varnish in the same sample, the differen...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
The purpose of this study was to evaluate the effect of different surface treatments of yttria-stabilized tetragonal zirconia (Y-TZP) on bond strength durability and marginal discrepancies. For adhesion testing, 144 specimens of VITA In-Ceram YZ ceramic for InLab were obtained (5.25×3.75×4.5 mm) and divided into six groups (n=24) according to the surface treatment: 1) Control (CRTL): untreated;...
achaemenid glazed bricks of archaeological excavation of tall-e-ajori in persepolis city were studied by multiple instrumental analysis methods such as xrf, xrd, sem-eds, icp and optical microscopy to identify the compositional features of glaze and brick body. glaze samples are apparently white and yellow and this phenomenon are caused by the deterioration processes in burial environment, he...
This paper examines inherent tensions between the medical glaze and that of an extended glaze, and the ways in which they historically have been brought out as conflicts over inspection schemes in the school medical service. Following an outline of two contrasting models of inspection, the empirical anallysis compares the early formation and shaping of inspection schemes in Britain and Norway.
The Seljuq arts is one of the most brilliant and prominent periods in Iranian art history, and considerable progress has been made in all the arts, including the pottery. The possibility of producing white bodies (white clay) due to the lack of kaolin was one of the Iranian potter’s long-standing aspirations. Iranian Seljuq potteries used a new artificial body called stone paste (Bādānehaye Jes...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
examining the role of glaze \vare pottery in the social lives of the late precontact and early contact Pueblos. By tracing the circulation of spe cialized knowledge, raw materials, and the glaze-painted pots themselves, through interactive networks ofvarying sizes and scales, these researchers reveal how glaze ware production, distribution, and use articulated with a variety of dynamic histori...
