  1. 1. Studies of auroral processes using optical methods

    Författare :Katarina Axelsson; Michael J. Taylor; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Sammanfattning : The Aurora is a visual manifestation of the complex plasma processes that occur as the solar wind interacts with the Earth’s magnetosphere and ionosphere. Therefore, studies of the aurora can lead to better understanding of the near-Earth space environment and of fundamental physical processes. LÄS MER

  3. 2. Cardiac effects of non-adrenergic inotropic drugs : clinical and experimental studies

    Författare :Birger Axelsson; Michael Haney; Hans Tydén; Anil Gupta; Patrick Wouters; Sven-Erik Ricksten; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milrinone; levosimendan; vein graft flow; myocardial ischemia; protection; inotropy; diastole; Anaesthesiology; anestesiologi;

    Sammanfattning : Background: Myocardial failure and dysfunction is not uncommon during critical illness and following cardiac surgery. For optimal treatment, a better understanding of the effects of inotropic drugs is needed. In this thesis, two non-adrenergic mediated inotropes, milrinone and levosimendan were studied in different models of myocardial dysfunction. LÄS MER

  4. 3. The Physiology of Chicken Domestication : Involvement of the HPA-axis and the Autonomic Nervous System

    Författare :Magnus Elfwing; Jordi Altimiras; Michael Axelsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Domestication; chickens; HPA-axis; autonomic nervous system; heart rate; allometry;

    Sammanfattning : Domesticering är en urvalsprocess för önskvärda egenskaper hos djur som över tid förändrar deras utseende, beteende och genetik. Några exempel av djur som genomgått denna riktade avel är vargen, mufflon, uroxen, vildsvinet och den röda djungelhönan som vi idag känner som hunden, fåret, kon, grisen och slaktkycklingen. LÄS MER

  5. 4. Development of Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer and its Application

    Författare :Anton Axelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dihydropyranone; Michael addition; kinetics.; aerobic oxidation; acylation; N-heterocyclic carbene; green chemistry; Organocatalysis; electron transfer mediator; asymmetric synthesis;

    Sammanfattning : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. LÄS MER

    Sammanfattning : The objective of this dissertation is literature discussion as a learning activity in school. The aim is to examine the conditions under which literature discussions may help students to develop their reception of a commonly read text, and to examine whether, and how, the discussions may provide the students with opportunities to learn more about, or to develop specific attitudes or perspectives towards, literary reading in general.
