Temp erature dependence s of the linear dimension L ( T ) and spontaneous polari zati on P s( T ) for tri glycine sulphate and glycine posphite single crystals have been measured in the same run of temp erature. A decrease in the spontaneous electrostriction coe£cient Q L of both crystals studied is displayed w hen approaching the corresp ondi ng phase transition point T c . A temp erature dep ...

The role of non polar optic phonon scatterin g and of umklapp acoustic phonon scattering is analy zed for a delocali zed p ositroni um atom in ionic crystals at elev ated temp eratures. A t temp eratures above w hich they become essential both of these scattering mechanisms contribute to the imagina ry self-energy of p ositroni um renormalizi ng its acoustic deformation potential constant. I t ...

This study evaluated the cytotoxicity of eugenol-containing and eugenol-free temporary luting cements. For cytotoxicity testing, bovine pulp-derived cells transfected with Simian virus 40 Large T antigen were exposed to extracts of eugenol-containing (Rely X Temp E) and eugenol-free (Provicol, PreVISION CEM, and Rely X Temp NE) temporary luting cements for 24 h. The cytotoxicity of the same mat...

The inÛuence of interstitial hydro gen concentration and structural defects caused by quenching of pallad iu m, b egun at di ̃erent temp eratures up to the temp erature of liqui d nitrogen or by stretching by external forces, on spectra of lif etimes of positrons in this metal w as investigated . I t w as found that the spectra of p ositron lif etimes in the examined systems are b est describ ed...

We use administrative data from the unemployment insurance system of the Sate of Washington to study the magnitude of the wage differential associated with work in the temporary services industry. We find that temp wage rates are 15% to 20% below the levels that might have been expected based on trends during other periods in workers’ careers even after controlling for differences between temps...

OBJECTIVE This study compared the marginal gap, internal fit, fracture strength, and mode of fracture of CAD/CAM provisional crowns with that of direct provisional crowns. MATERIAL AND METHODS An upper right first premolar phantom tooth was prepared for full ceramic crown following tooth preparation guidelines. The materials tested were: VITA CAD-Temp®, Polyetheretherketone "PEEK", Telio CAD-...
