## Abstract A study has been made of the effects of sandblasting on the strength of YβTZP and alumina ceramic layers joined to polymeric substrates and loaded at the top surfaces by a spherical indenter, in simulation of occlusal contact in ceramic crowns on tooth dentin. The sandblast treatment is
The mechanism resulting in damage to and failure of ultrahigh molecular weight polyethylene (UHMWPE) tibial inserts was investigated on clinically retrieved components. The severity of the subsurface damage increased with the length of time that the component had been implanted. A theoretical analys
Twelve patients were assessed prior to and during 4 weeks' graded withdrawal from long-term benzodiazepine treatment. A control group of ten healthy drug-free individuals were assessed over the same period. Psychometric measures included Four Choice Reaction Time--Decision (FCRT-D), Four Choice Reac
An opportunity arose in 1985 to become involved in a transition of working practice from hard copy to VDT. Over a two-year period, 161 VDT users and 65 control subjects in the same office environment were regularly and routinely examined for symptoms of asthenopia. The analysis of data shows that th
