Casting metals in dentistry: past--present--future.
This article deals mainly with the development of dental casting techniques and formulation of the different groups of alloys used in the fabrication of ceramo-metal restorations. It is recognized that in order for the quality of dental cast restorations to be improved, having alloys with the proper composition is not enough. Biocompatibility, good mechanical and physical properties, longevity ...
متن کاملSmall Intestinal Biopsy Specimens
The effect of 5-hydroxytryptamine (5-HT) on the crypt cell production rate in normal human duodenal mucosa cultured in vitro was studied using a stathmokinetic technique with crypt microdissection. The addition of 5-HT (2 mg/ml) to the culture medium significantly increased the crypt cell production rate (p < 000 1), suggesting that this amine may have a trophic effect on crypt cells in vitro. ...
متن کاملTrace Characterization of Refractory Metals by Activation Techniques
The application of activation techniques to the assay of the refractory metals niobium, molybdenum, tantalum and tunjsten for their trace element impurities is reviewed. Activation with reactor neutrons, fast neutrons, charged partides and photons in connection with both the non-destructive and the radiochemical performance is considered. The decisive contribution of activation techniques to th...
متن کاملCasting of Lead-free Solder Bulk Specimens With Various Solidification Rates
The casting of lead-free solder bulk samples has been investigated by varying the conditions of solidification. Two sets of samples were generated, one water-quenched and the other air-cooled. From these cast samples, tensile testing specimens were produced for the investigation of their mechanical properties. Cooling rate effects were specifically analyzed using small solder droplets. Excellen...
