  1. 6. Palaeodiet and Infant Feeding in Coastal Arctic Settlements : Insights from stable isotope analysis of bone and dentine collagen and amino acids

    Författare :Alison Harris; Gunilla Eriksson; Kerstin Lidén; Michelle Alexander; Tamsin O'Connell; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Arctic; palaeodiet; Inuit; Yup’ik; infant feeding; domestic dogs; amino acids; collagen; stable isotopes; maintenance activities; gender; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

    Sammanfattning : This dissertation investigates the day-to-day activities that sustained human societies in the arctic and subarctic environments of North America and Siberia over the past 1500 years. Maintenance activities, such as food preparation, childcare, and the care of domestic animals, are commonly inflected by social identity and can provide insight into the experience of gender among archaeological and historical populations.

  3. 7. On Caries Prevention Using Fluoridated Toothpicks and Dental Flosses

    Författare :Barbro Särner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The prevalence of approximal dental caries is still high worldwide in all age groups. The aim was to evaluate different aspects of fluoridated toothpicks and dental flosses in relation to caries prevention with the emphasis on the approximal area. LÄS MER

  4. 8. Molecular, micro- and ultrastructural investigations of labile tissues in deep time

    Författare :Johan Gren; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; eumelanin; fossils; histology; integument; IR microspectroscopy; melanin; melanosomes; molecular palaeontology; ToF-SIMS; XAS;

    Sammanfattning : This thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods.

  5. 9. On approximal caries prevention using fluoridated toothpicks, dental floss and interdental brushes

    Författare :Barbro Särner; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Approximal caries; Dental flosses; De- and re-mineralization; Fluoride; Interproximal aids; Interproximal area; Oral hygiene; Questionnaire; Toothpicks;

    Sammanfattning : Although dental health has improved during the last 40-50 years, approximal caries still constitutes a problem in many age groups. It is important that fluoride (F) toothpaste is used when brushing the teeth. In some subjects, there may be a need for supplementary F products, especially in the caries-prone approximal area.

  7. 10. Calcium Aluminate based Cement as Dental Restorative Materials

    Författare :Lars Kraft; Charles Lloyd; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : This thesis presents the results from the development process of a ceramic dental filling material based on calcium aluminate cement. The main focus of the work concerns dimensional changes during setting, hardening and curing and the understanding of the factors controlling the dimensional stability of the system. LÄS MER
