  2. 1. Diurnal variation of stratospheric short-lived species

    Author : Maryam Khosravi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chlorine monoxide; short-lived species; Arctic ClO; diurnal variation; tropical middle stratosphere; Arctic stratosphere;

    Abstract : 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.

  4. 2. Radar Measurements of Temporal Variation in a Boreal Forest

    Author : Albert Monteith; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Abstract : 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. READ MORE

  5. 3. Monitoring Arthritis - Biochemical, Metodological and Clinical Aspects

    Author : Maria Andersson; Reumatologi och molekylär skelettbiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Monitoring; COMP; CRP; Biomarkers; Rheumatoid Arthritis; Arthritis; Osteoarthritis; Clinical; Diurnal variation;

    Abstract : 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. READ MORE

  6. 4. Interference with biological rhythm : a novel approach to metabolic disorders in women

    Author : Roger Karlsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; GH; cholecystokinin; CCK; osteocalcin; angiotensinogen; diurnal variation; oral contraception; pregnancy; menopause;

    Abstract : 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. READ MORE

  7. 5. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling

    Author : Ramin Ghorbani; Florian M. Schmidt; Anders Blomberg; Christoffer Boman; Staffan Schedin; Jonathan Beauchamp; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon monoxide CO ; pulmonary gas exchange; computational modeling; real-time breath gas analysis; single-exhalation profile; laser absorption spectroscopy; nonlinear least-squares fitting; breath sampling; baseline level; diurnal variation; healthy population; exposure study; fysik; Physics; Physiology; fysiologi;

    Abstract : 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.
