Pore Structure Evolution and Its Effect on Strength Development of Sulfate-Containing Cemented Paste Backfill
In this study, the effects of the initial sulfate content on the properties of cemented paste backfill (CPB) made from coarse tailings has been investigated via mercury intrusion porosimetry. The combined effects of the sulfate content and curing time on the total porosity, pore size distribution, and unconfined compressive strength of the produced material were discussed. It was found that the...
متن کاملThe Retentive Strength of Cemented Zirconium Oxide Crowns after Dentin Pretreatment with Desensitizing Paste Containing 8% Arginine and Calcium Carbonate.
The effect of dentin pretreatment with Desensitizing Paste containing 8% arginine and calcium carbonate on the retention of zirconium oxide (Y-TZP) crowns was tested. Forty molar teeth were mounted and prepared using a standardized protocol. Y-TZP crowns were produced using computer-aided design and computer-aided manufacturing (CAD-CAM) technology. The 40 prepared teeth were either pretreated ...
متن کاملCemented and non-cemented replacements of the trapeziometacarpal joint.
We performed 88 primary ball-and-socket arthroplasties of the trapeziometacarpal joint in 84 patients (69 women and 15 men) with a mean age of 61 years (37 to 81). Cemented de la Caffinière prostheses were implanted in 43 joints from 1988 to 1991 and 45 cementless Ledoux implants were used between 1992 and 1994. Of the 61 surviving prostheses still in situ, 51 were reviewed clinically and radio...
متن کاملCemented Thompson versus cemented bipolar prostheses for femoral neck fractures.
PURPOSE To compare early functional outcomes, complications, and mortality in elderly patients treated with the less costly, cemented Thompson prosthesis or the cemented bipolar prosthesis in order to identify factors affecting outcomes. METHODS Records of 303 patients with femoral neck fractures treated with the cemented Thompson monoblock prosthesis (n=206) or the cemented bipolar prosthesi...
متن کاملCopy and paste redeemed
Software development relies critically on code reuse, which software engineers typically realise through handwritten abstractions, such as functions, methods, or classes. However, such abstractions can be challenging to develop and maintain. One alternative form of re-use is copy-paste-modify, a methodology in which developers explicitly duplicate source code to adapt the duplicate for a new pu...
