BACKGROUND Studies comparing the measurement properties of EQ-5D 3L (3L) and EQ-5D 5L (5L) are limited to specific patient populations with small sample sizes. Using a general population sample, we compared 3L and 5L in terms of their measurement properties and association with number of chronic conditions, including multimorbidity--the concurrent occurrence of two or more chronic conditions. ...

INTRODUCTION The new, five-level version of the EQ-5D (EQ-5D-5L) questionnaire has better psychometric properties than the standard three-level version (EQ-5D-3L), including a reduced ceiling effect. Currently, there are few existing population norms for the EQ-5D-5L. The aims of this study were to provide population norms for the EQ-5D-5L in Poland, based on a representative sample of adults, ...

Experiments in a large-scale flow loop provide an example of a somewhat increased corrosion rate under multiphase flow conditions caused by a low concentration of H2S in a CO2 saturated environment. Under operating conditions that prevent scale formation, the addition of 3ppm H2S in the gas phase increased the corrosion rate of AISI C 1018 and API 5L X-65 carbon steels, while the addition of H2...
