Effect of Thermomechanical and Static Loading on the Load to Fracture of Metal‐Ceramic, Monolithic and Veneered Zirconia Posterior Fixed Partial Dent…
2018
PURPOSE To evaluate the influence of static (not preloaded) and thermomechanical loading on the load to fracture of metal-ceramic, monolithic and veneered zirconia computer-aided design/computer-aided manufacturing (CAD/CAM) posterior fixed partial dentures (FPDs). MATERIALS AND METHODS One hundred standardized specimens with 2 abutments screwed onto a platform were prepared from stainless steel to receive a posterior 3-unit FPD with an intermediate pontic. Specimens were randomly divided into 5 groups (n = 20): Metal-ceramic (control group), Lava Zirconia system, Vita In-Ceram YZ, IPS e.max ZirCAD, and Lava Plus. Half of the specimens of each group (n = 10) underwent no preloading, and the…
Disinclusion of unerupted teeth by mean of self-ligating brackets: Effect of blood contamination on shear bond strength
2012
Objectives: The aim of this study was to assess the effect of blood contamination on the shear bond strength and failure site of three different orthodontic self-ligating brackets. Study Design: 240 bovine permanent mandibular incisors were randomly divided into 12 groups of 20 specimens each. Orthodontic self-ligating brackets were tested under four different enamel surface conditions: a) dry, b) blood contamination before priming, c) blood contamination after priming, d) blood contamination before and after priming. Brackets were bonded to the teeth and subsequently tested using a Instron universal testing machine. Shear bond strength values and adhesive failure rate were recorded. Statis…
In vitro retentive strength of zirconium oxide ceramic crowns using different luting agents
2005
Statement of problem In contrast to gold crowns, in vitro determination of the retentive strength of all-ceramic crowns is more difficult because components allowing connection to testing apparatus are not as easily integrated into the all-ceramic material. Nevertheless, retentive strength data are crucial for obtaining information about the potential clinical performance of luting cements for all-ceramic restorations. Therefore, a new in vitro model was necessary to evaluate the retentive strength of all-ceramic crowns. Purpose The purpose of this in vitro study was to determine the retentive strength of 4 resin-cement systems, a compomer, a glass-ionomer cement, a resin-modified glass-ion…

GW170817: Measurements of Neutron Star Radii and Equation of State
2018
On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational-wave signal, GW170817, offers a novel opportunity to directly probe the properties of matter at the extreme conditions found in the interior of these stars. The initial, minimal-assumption analysis of the LIGO and Virgo data placed constraints on the tidal effects of the coalescing bodies, which were then translated to constraints on neutron star radii. Here, we expand upon previous analyses by working under the hypothesis that both bodies were neutron stars that are described by the same equation…
Health care systems of developed non-U.S. nations: strengths, weaknesses, and recommendations for the United States--observations from internationall…
2010
The purpose of this article is to survey imaging experts from developed nations on their impression of their own health care system and recommendations for the U.S. health care system as it seeks to enact health care reform.A survey was sent to individual imaging experts from developed nations requesting information on their health care systems (type of system, strengths, and weaknesses) and their recommendations for the United States.Eighteen respondents from 17 developed nations completed the survey. All respondents reported universal health care coverage: four with government-operated health care, one with mixed government and private insurance-operated health care, 10 with predominantly…
Habermas’ Universal Pragmatics: Theory of Language and Social Theory
2013
Although Habermas’ universal pragmatics has played a marginal role in studies on pragmatics, it can still make an important and meaningful contribution, precisely because it highlights the system of validity claims that lie in speech acts. This type of analysis allows one to consider the dialogic dynamics that engage speakers in the activity of reciprocal giving and asking for reasons for saying and doing things. The reasons why a speaker knows he or she can say what he or she says in the presence of other speakers constitute an essential element of the production of meaning; and reciprocally identification of the speaker’s reasons by the listener is an indispensable condition of the activi…
