  2. 1. Functional Degradable Polymers : from the monomeric point of view

    Author : Peter Olsén; Ann-Christine Albertsson; Karin Docent; Andrew Dove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Degradable polymers is key, within the future vison, of creating a sustainable society were all aspects, cradle to grave, can be realized in a sustainable way. It is imperative to consider, how the monomer is formed, its polymerization, the material properties created and the final degradation behavior. READ MORE

  4. 2. Perinatal nicotine exposure. Effects on the defense against hypoxia in lambs

    Author : Ola Hafström; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid body; nicotine; prenatal exposure delayed effects; respiration; respiratory mechanics; sudden infant death; smoking; tobacco;

    Abstract : The aim of the present study was to evaluate whether perinatal nicotine exposure could impair cardiorespiratory defense mechanisms to hypoxia. The rationale for this approach is that exposure to tobacco smoke, particularly before birth, is a risk factor for the sudden infant death syndrome as well as for obstructive airway disease in childhood.

  5. 3. Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler

    Author : Solweig Harling; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. READ MORE

  6. 4. Evaluation of efficacy and safety of pulsed inhaled nitric oxide in the anesthetized horse : preparing for clinical use

    Author : Tamara Grubb; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Anesthetized, recumbent horses commonly develop hypoxemia secondary to ventilation/perfusion (VA/Q) mismatch and shunting of pulmonary blood (Qs/Qt) through atelectatic lung regions. Hypoxemia in the anesthetized horse is difficult to treat and ventilatory therapy is often ineffective. READ MORE

  7. 5. From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society

    Author : Gurpreet Kaur-Kahlon; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Bacteria; Climate change; Quorum sensing; Microbial blooms; Vulnerability factors; Arabian Sea; Southwest India;

    Abstract : Unicellular organisms, microalgae and bacteria, less than one millimeter in size make the world go round. Phytoplankton and cyanobacteria, for example, plays an inevitable role contributing 50-85% to the world’s oxygen via photosynthesis. READ MORE
