    Sammanfattning : From the begiining of the 20th century producer co-operative bacon factories were established in the south of Sweden. In his thesis Lars Hansson studies how class relations were shaped and transformed within this rural industry. LÄS MER

  3. 2. Acute Abdominal Pain

    Författare :Helena Laurell; Ulf Gunnarsson; Lars-Erik Hansson; Lars Påhlman; Rune Sjödahl; Uppsala universitet; []
    Nyckelord :Surgery; acute abdominal pain; diagnostic pitfalls; decision-making; competence; sensitivity; specificity; high age; acute appendicitis; Kirurgi;

    Sammanfattning : The aim was to identify diagnostic difficulties for acute abdominal pain at the emergency department and during hospital stay. A total of 3349 patients admitted to Mora Hospital with acute abdominal pain of up to seven days duration, were registered prospectively for history and clinical signs according to a structured schedule.

  4. 3. Controlling microwave heating and its effect on the properties of wood

    Författare :Lars Hansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Drying wood with microwave energy is not so common, but could be a complement to conventional air circulation drying due to the possibility of drying wood faster than with conventional drying methods with preserved quality. An industrial-scale, on-line microwave drier for wood components is under development at the Division of Wood Physics. LÄS MER

  5. 4. Microwave treatment of wood

    Författare :Lars Hansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Drying wood using microwave energy is not very common, but could be a complement to conventional air-circulation drying due to the possibility to dry wood faster than the conventional drying methods with preserved quality. Furthermore, this technique could be used to condition boards with too high moisture content gradient. LÄS MER

  7. 5. Optimering i organisk syntes : betingelser, system, syntesvägar

    Författare :Lars Hansson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; Response surface method; PLS method; Silylation; Enolether; Unsaturated ketones; Diketones; Geosmin synthesis; Onepot procedure;

    Sammanfattning : This thesis deals with different optimization problems encountered in organic synthesis. The use of response surface, sequential simplex and PLS techniques, for simultanious optimization of yield and suppression of side reactions is investigated. This is illustrated by an example of enamine synthesis, were a side reaction was a serious problem. LÄS MER
