2. 1. Capnodynamic determination of effective pulmonary blood flow and end expiratory lung volume : studies in children and paediatric animal models

   Author : Jacob Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : cardiac output children;

   Abstract : Dynamic capnography is a haemodynamic and respiratory monitoring technique enabling continuous cardiac output (Effective Pulmonary Blood Flow, COEPBF) and end expiratory lung volume (Effective Lung Volume, ELV) assessment in mechanically ventilated subjects. The method utilizes variations in exhaled CO2, implemented via periods of deliberate changes in the respiratory pattern. READ MORE

4. 2. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies

   Author : Carsten Meyer-Jacob; Richard Bindler; Hendrik Vogel; Jan Karlsson; John F. Boyle; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fourier transform infrared spectroscopy; visible-near infrared spectroscopy; PLS regression; biogenic silica; climate change; carbon cycling; lake-water quality; geochemistry; paleolimnology; Holocene; Lake El’gygytgyn; Torneträsk;

   Abstract : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. READ MORE
