  1. 1. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements

    Författare :Karin Margaretha Borgström; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.

  5. 5. Dental Anxiety: prevalence, measurements and consequences

    Författare :Lisa Svensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental anxiety; adults; prevalence; oral health; oral health-related quality of life; dental pain; measurements; validity; dental phobia;

    Sammanfattning : The overall aim of this thesis was to gain knowledge about adults suffering from dental anxiety by studying the current prevalence of dental anxiety and concomitant factors, the impact of dental pain on everyday life among individuals suffering from severe dental anxiety, and to evaluate the validity of a psychometric measurement, the IDAF-4C+, used to measure the level of dental anxiety and to screen for a diagnosis of specific phobia for dentistry. The included studies have a cross-sectional design. LÄS MER
