    Sammanfattning : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. LÄS MER

  3. 2. Oral health and experience of oral care among cancer patients during radio- or chemotherapy

    Författare :Kerstin Öhrn; Uppsala universitet; []
    Nyckelord :Medical sciences; oral health. oral status; health-related quality of life; oral care; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Sammanfattning : Oral complications and symptoms are common among patients with cancer. The aim of this thesis is to study several aspects of oral status, oral health and its relation to quality of life, and oral care among patients treated with radiotherapy or chemotherapy. Descriptive, comparative and correlational designs were used. LÄS MER

  4. 3. Carbon castles vs. beetle-fungus armies : phenology of the spruce bark beetle and Norway spruce resistance in times of climate change

    Författare :Petter Öhrn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In recent years, carbon sequestration in European forests has decreased due to extensive droughts and bark beetle outbreaks brought on by climate change. The Eurasian spruce bark beetle (Ips typographus (L.)) is a natural disturbance agent in forests where Norway spruce (Picea abies (Karst)) is dominant. LÄS MER

  5. 4. Seasonal flight patterns of the Spruce bark beetle (Ips typographus) in Sweden : phenology, voltinism and development

    Författare :Petter Öhrn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The major bark beetle threat to Norway spruce (Picea abies (L.) Karst.) in Eurasia is the spruce bark beetle Ips typographus. Beetles cause damage after population build-up in defenseless trees. LÄS MER
