1. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling
Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

2. Characterization of Chimney Flue Gas Flows : Flow Rate Measurements with Averaging Pitot Probes
Sammanfattning : Performance testing methods of boilers in transient operating conditions (start, stop and combustion power modulation sequences) need the combustion rate quantified to allow for the emissions to be quantified. One way of quantifying the combustion rate of a boiler during transient operating conditions is by measuring the flue gas flow rate. LÄS MER

4. New Efficient Detector for Radiation Therapy Imaging using Gas Electron Multipliers
Sammanfattning : Currently film is being replaced by electronic detectors for portal imaging in radiation therapy. This development offers obvious advantages such as on-line quality assurance and digital images that can easily be accessed, processed and communicated. LÄS MER
5. Thin films for indoor air monitoring : Measurements of Volatile Organic Compounds
Sammanfattning : Volatile organic compounds (VOCs) in the indoor air have adverse effects on the dwellers residing in a building or a vehicle. One of these effects is called sick building syndrome (SBS). LÄS MER
