The use of slow heating and slow cooling regimens to strengthen porcelain fused to zirconia.
STATEMENT OF PROBLEM Porcelain fused to zirconia prostheses are widely used. However, porcelain chipping, spalling, fracture, and delamination are common clinical problems. Residual stresses of thermal origin have received attention, but clear data and firing guidelines remain absent. PURPOSE The purpose of this study was to measure the influence of heating and cooling protocols on the streng...
متن کاملO-20: Slow-Freezing-Induced Changes of Birefringent Structures in Human Oocytes Are Related to Responsiveness to Ovulation Induction
Background: The slow-freezing method is one of the most popular techniques to freeze human oocytes and it is also used in routine in vitro-fertilization (IVF) programs, particularly in those countries where embryo freezing is not allowed. Slow-freezing damages some of the structures of the egg, among which the meiotic spindle (MS) and the zona pellucida (ZP). Polarized Light Microscopy (PLM) pe...
متن کاملSlow Heating Methods in Tandem Mass Spectrometry
Several approaches to ion activation in tandem mass spectrometry have been developed in recent years for use in ion trapping instruments that allow for conditions to be reached wherein rates of ion activation and deactivation are comparable. These approaches are deÐned as slow heating methods and include continuous-wave laser infrared multiphoton dissociation, dissociation driven by blackbody r...
متن کاملCombinatorial Structures to Represent Simple Games
We connect three different topics: combinatorial structures, simple games and influence games. We establish the bases to represent some simple games or some influence games by using combinatorial structures. These considerations are also able to generate any object of any topic based in graphs, for instance, molecules applied to chemistry, among others. Key–Words: Combinatorial Structures, Gene...
متن کاملFeedback Heating with Slow Jets in Cooling Flow Clusters
We propose a scenario in which a large fraction, or even most, of the gas cooling to low temperatures of T < 10 K in cooling flow clusters, directly gains energy from the central black hole. Most of the cool gas is accelerated to nonrelativistic high velocities, vj ≃ 10 3 − 10 km s, after flowing through, or close to, an accretion disk around the central black hole. A poorly collimated wind (or...
