  1. 16. Pulmonary hypertension and heart failure : physiological markers assessed by cardiovascular magnetic resonance

    Författare :João Ramos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pulmonary hypertension (PH) is clinically and physiologically associated with heart failure, both with reduced and preserved ejection fraction (HFrEF and HFpEF). In HFpEF, the most likely underlying pathophysiological mechanism is an impairment of left ventricular relaxation named diastolic dysfunction. LÄS MER

  3. 17. Optimising pulmonary gas exchange in anaesthetised horses : unravelling the role of pulsed inhaled nitric oxide using computed tomography angiography of the lung

    Författare :Adam Auckburally; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Mortality rates in healthy, anaesthetised horses are higher than in most other species. Hypotension, hypoxaemia and hypoventilation are implicated as risk factors, which develop due to the combined effects of general anaesthesia and recumbency. Hypoxaemia is largely a consequence of ventilation perfusion (V̇ /Q̇ ) mismatch. LÄS MER

  4. 18. Fish population responses to climate change : Causes and consequences

    Författare :Matilda L. Andersson; Peter Eklöv; Brian Hayden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; browning; climate change; DOC; intraspecific variation; metabolism; resource use; warming;

    Sammanfattning : Lake environments are heterogeneous, and animals show a variety of adaptations to deal with this heterogeneity. Fish often show intraspecific variation in diet, metabolism, and behavior, corresponding to their habitat use. LÄS MER

  5. 19. Nonfatal injuries in a local context - Analysing social structures and perceptions in young people

    Författare :Richard Allan Dale; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nonfatal injuries; socioeconomic structure; genus structure; alcohol culture; children s perceptions; children s explanations; young adults; near injury situations;

    Sammanfattning : Background: Injuries are a common health problem in children and young people. The uneven distribution over gender and socioeconomic groups is partly explained by factors at both the individual and family levels, but sociocultural structures at the municipality level may contribute with yet unrecognised associations.

  7. 20. On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines

    Författare :Henrik Bladh; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Incandescence; Laser Diagnostics; LII; Soot; Model; Engine; Particulates; Soot volume fraction; Combustion; Physics; Fysik; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; relativity; kvantmekanik; klassisk mekanik; termodynamik; statistisk fysik; relativitet; Gases; Gaser; fluid dynamics; plasmas; Teknik; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; fluiddynamik; plasma; Technological sciences; Laser technology;

    Sammanfattning : The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. LÄS MER
