1. Diurnal variation of stratospheric short-lived species
Sammanfattning : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

2. Radar Measurements of Temporal Variation in a Boreal Forest
Sammanfattning : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. LÄS MER
3. Monitoring Arthritis - Biochemical, Metodological and Clinical Aspects
Sammanfattning : Arthritides are musculoskeletal diseases, which predominantly affect the joints e.g. osteoarthritis (OA) and rheumatoid arthritis (RA). Modern treatment strategies include early detection and careful monitoring of the disease course. LÄS MER
4. Interference with biological rhythm : a novel approach to metabolic disorders in women
Sammanfattning : Women seem to be largely protected against certain ‘welfare disorders’ such as cardiovacular disease and osteoporosis, during their fertile years.The metabolic changes observed during women’s non-menstrual states, i.e. LÄS MER
5. 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.
