The aim of this study was to evaluate the following acrylic resins: Clássico, QC-20 and Lucitone, recommended specifically for thermal polymerization, and Acron MC and VIPI-WAVE, made for polymerization by microwave energy. The resins were evaluated regarding their surface nanohardness and modulus of elasticity, while varying the polymerization time recommended by the manufacturer. They were al...

A copula-based approach is used to estimate the dependence among three lumber strength properties: modulus of elasticity ( MOE ), rupture MOR and ultimate tensile UTS ). are destructive measurements so they cannot be obtained simultaneously for specimens. The modeling possible under an appropriate experimental design with i) a shoulder group rupture, ii) tension, iii) other groups proof loaded ...

The modulus of elasticity of dental amalgam has been determined by analysis of creep data (OGLESBY ET AL, J Res Natl Bur Stan 72C: 203, 1968) and by ultrasonic methods (DICKSON and OGLESBY, J Dent Res 46: 1475, 1967; HALL ET AL, J Dent Res 52: 390, 1973) to be between 63,000 and 70,000 MN/m2. These values represent the instantaneous elastic compliance term when dental amalgam is treated as a vi...

the testing equipment and the methods of field tests used for calculating the modulus of deformation and elasticity of the shah _ abass dam foundation rock are described here. the communication includes conclusions of which a sharp difference between the quality of the roc kin the right and in the left bank is the most important.

The effective utilization of the inner part oil palm trunk (OPT), generally considered a waste product, is desired. In this study, particleboards were manufactured using OPT with bio-based adhesive made sucrose and ammonium dihydrogen phosphate (ADP). mixture ratio to ADP resin content changed investigate optimum condition adhesive. pressing was set at 180 °C for 10 min, target density 0.8 g/cm...

OBJECTIVE To define the modulus of elasticity for nasal septum, auricular, upper lateral, and lower lateral cartilages. METHODS Prospective enrollment of sequential patients undergoing septorhinoplasty. Test samples were obtained through routine surgical interventions using atraumatic harvesting techniques. The modulus of elasticity was determined using a customized biomechanical testing devi...
