Quantification of the Formaldehyde Emissions from Different HCCI Engines Running on a Range of Fuels
, 2005 In this paper, the formaldehyde emissions from three different types of homogenous charge compression ignition (HCCI) engines are quantified for a range of fuels by means of Fourier Transform Infra Red (FTIR) spectroscopic analysis. The engines types are

European long‐term care marketisation: A political economy framework
Social Policy &Administration, Volume 58, Issue 7, Page 1059-1074, December 2024.Abstract The study of European long‐term care (LTC) marketisation is dominated by institutional and ideational perspectives. In contrast, political economic theoretical frameworks have received little attention. This is paradoxical, because marketisation is an inherently political economic phenomenon.
