Aim: The aim of this study was to compile the usage of Co-Cr alloys in fixed prosthodontics (FP) among dental laboratories in Sweden. Methods: From March to October 2015, questionnaires were sent to 542 registered dental laboratories in Sweden. The questionnaires were divided in two parts, one for fixed dental-supported prosthodontics (FDP) and one for fixed implant-supported prosthodontics (FI...

Evaluation of Pre-Fixed Biological Tissues Preparation Methods for ATR-FTIR Biospectroscopy Fourier transform infrared (FTIR) spectroscopy in ATR (attenuated total reflection) mode is a powerful tool for studying biomedical samples, which can provide important structural information on the molecular composition. Currently, formalin fixation and paraffin preservation (FFPP) is the preferred sourc...

most of the plutonium isotopes are alpha-emitters, a fact which is of decisive importance from a biological point of view. we shall consider their potential danger to life in general, and to human life in particular. in this respect measurement of plutonium concentration in air and soil and vegetable is the object of systematic tests in numerous countries. this plutonium occurs in the fallout f...
