OBJECTIVE To investigate the two-body wear performance of monolithic dental ceramics with different surface treatments. METHOD AND MATERIALS Standardized specimens (n = 8/ series) were fabricated from three monolithic dental ceramics (experimental translucent zirconia, experimental shaded zirconia, lithium disilicate). Four groups of each material were defined according to clinically relevant...

In this expository paper we show how one can, in a uniform way, calculate the weight distributions of some well-known binary cyclic codes. The codes are related to certain families of curves, and the weight distributions are related to the distribution of the number of rational points on the curves.

Radio pulsar observations can be used to test aspects of general relativity from equivalence principle violations to binary orbital effects in the strong-field regime. This article summarizes the status of such tests at the start of the meeting, and describes two new tests made possible by recent observations of well-known binary pulsar systems.

Purpose: Inability of ceramists to formulate glazes locally and the cost importing had resulted closure many cottage ceramic industries in Nigeria. The study, physicochemical characterization cullet glaze, was conducted with aim recycling for glazing earthen wares intention conduct elemental analysis waste glass glaze recipes, determine its artistic usage, lessen from environment harness chemic...

CAD-CAM sistemlerinde üretilen tam seramik ve benzeri malzemeler yapılan sınıflandırma sistemine göre; cam maktriks seramikler, polikristalin seramikler rezin matriks olarak üç gruba ayrılmaktadır. Geliştirilen yeni materyallerden monolitik tasarlanıp restorasyonlar, yüksek dayanıklılığa sahip bir altyapı tarafından desteklenip ışık geçirgenliği fazla olan seramikle veneerlenen tabakalı restora...
