The prevalence of QTc-prolongation increase by GOLD stage in COPD

TL;DR: In this population based study, the prevalence of prolonged QTc was similar among subjects with NLF and COPD, and the prevalence increased by COPD severity, among men also when adjusted for common confounders.
Journal ArticleDOI

Two-Dimensional Gas-Phase Temperature Measurements Using Laser-Induced Phosphor

TL;DR: In this paper, a new technique based on phosphor thermometry, for measurements of two-dimensional gas-phase temperature in combustion was established as a new laser diagnostic, and the temperature calibration of Dy : YAG phosphor was taken at a surface of solid.
Proceedings ArticleDOI

A Novel Model for Computing the Trapping Efficiency and Residual Gas Fraction Validated with an Innovative Technique for Measuring the Trapping Efficiency

TL;DR: In this paper, a method for calculating the residual gas fraction and the trapping efficiency in a 2-stroke HCCI engine was proposed, which is based on perfect displacement and perfect mixing scavenging models.
