Gold Mosaic glass has been used to decorate items and places since ancient time. The glass structure is divided into three layers: cover glass, gold layer and glass substrate. In this study, the composition of old-styled Thai gold mosaic glass samples was analyzed using SEM/EDX and Raman spectroscopy. It was found that the glass composition was sodiumsilicate based glass. Raman spectroscopy als...

We present an algorithm that models stained glass in a physicallyrealistic manner. Stained glass is made by melting glass material with metal oxides that determine the color. Metal oxides are scattered in the glass, and we model it by distributing metal oxides in the volume defined by the glass. We render our stained glass model using a modified photon mapping. Our model is capable of modeling ...

The presence of glass-like contaminants inside waste glass products, usually resulting from both industrial and differentiated urban waste collection, has greatly increased in recent years, due to the introduction to the market of a large amount of goods manufactured from ceramic glass. The presence of contaminants in the glass recycling streams reduces product quality and increases production ...

 This study aimed to investigate the impact of N-vinylcaprolactam (NVC) and Nano-sized yttria-stabilized zirconia (YSZ), separately and simultaneously, on the mechanical properties of the commercial glass ionomer cements (GICs). Methods: The NVC is able to ameliorate the mechanical and surface properties of glass ionomers; however, its effect hasn’t been investigated in conjunc...

In daily activity, much time is spent indoors and in vehicles. Although the adverse effect of ultraviolet (UV) radiation is now well recognized and active public education programs on photoprotection have been undertaken, the role of window glass in photoprotection has been rarely addressed. It has been known for some time that window glass filters out UVB and transmits UVA and visible light. R...

OBJECTIVE Glass carbomer cement represents a new generation of dental material, which mineralizes gradually into fluorapatite. The aim of this study was to evaluate the microleakage and marginal integrity of newly developed glass carbomer cement with and without protective surface coating (SC) in primary molars. METHODS Standardized cavities were prepared on extracted human primary molars, an...

the aim of this study was to evaluate the effect of the glass ceiling on women creative ideas working in administrative province units of lorestan state with moderating of their self-concept variable. the population of this cross-correlation study included all women employees of administrative province units of lorestan state. using stratified sampling, and based on morgan table, 306 persons we...

The left-right chiral and ferromagnetic-antiferromagnetic double-spin-glass clock model, with the crucially even number of states q=4 and in three dimensions d=3, has been studied by renormalization-group theory. We find, for the first time to our knowledge, four spin-glass phases, including conventional, chiral, and quadrupolar spin-glass phases, and phase transitions between spin-glass phases...
