Because of the significant difference between thermal expansion coefficients ceramic blank and glaze, glaze typically undergoes more pronounced shrinkage than during cooling, which results in high stress concentrations cracking. In this study, mechanical mechanism cracking is studied, based on statistical strength theory, damage mechanics, continuum mechanics. Furthermore, influence layer thick...

To study the effect of different cooling rates after glaze firing on Radius of radial crack, Fracture toughness and Microhardness of Alumina reinforced porcelain. Total 30 porcelain discs reinforced with aluminium oxide of 8mm diameter×0.6mmthickness were prepared. Specimens were divided into three groups, each group containing ten discs. They were positioned at the entrance of the furnace with...

History Guy Leroy Hunner, a Boston gynaecologist, described this inflammatory bladder disease a century ago in great detail for the first time in a series of papers, the first being published in 1914 (republished in 1915). In this first paper he writes: “While cystoscopy usually reveals only one inflammatory spot, there may be two or three granulation areas near together or somewhat separated, ...

Rheumatoid arthritis is a complex disease where predetermined and stochastic factors conspire to confer disease susceptibility. In light of the diverse responses to targeted therapies, rheumatoid arthritis might represent a final common clinical phenotype that reflects many pathogenic pathways. Therefore, it might be appropriate to begin thinking about rheumatoid arthritis as a syndrome rather ...

Abstract This study identified the provenance of Pb flux used in production glaze unique, high‐quality late medieval stove tiles from northern part Carpathian Basin, and elaborated evaluated a fast preparation process to measure isotope ratios high‐Pb glazes. We compared three different methods preparation. Method 1 consisted dissolution bulk chips glaze, dilution solution mass spectrometric an...

Public announcement logic is an extension of multi-agent epistemic logic with dynamic operators to model the informational consequences of announcements to the entire group of agents. We propose an extension of public announcement logic with a dynamic modal operator that expresses what is true after any announcement: ♦φ expresses that there is a truthful announcement ψ after which φ is true. Th...

An important segment of the functional food market is products confectionery industry covered with chocolate or glaze for a healthy diet. The selection high-quality and technological fat ingredients such often difficult due to specific properties in composition. additional source concern realization that there are limited number vegetable oils fats nature have optimal crystallization melting ch...
