  1. 1. The evolutionary ecology of plant reproductive diversity and floral signals : Mating system and floral scent in Arabis alpina

    Författare :Hampus Petrén; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabis alpina; floral scent; intraspecific variation; mating system; parental conflict; phenotypic plasticity; phenotypic selection; reproductive isolation; speciation; volatile organic compound VOC ;

    Sammanfattning : Flowering plants display an extraordinary floral- and reproductive diversity. Variation in the size, shape, colour and scent of flowers, and in systems and strategies of mating, is ubiquitous in comparisons of different species, but also exists among different conspecific populations.

  3. 2. Correction of unilateral posterior crossbite in the mixed dentition : studies of treatment effects, stability and cost-effectiveness

    Författare :Sofia Petrén; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthodontics; evidence-based orthodontics; early treatment; maxillary expansion; crossbite correction;

    Sammanfattning : Enkelsidigt korsbett är en av de vanligaste bettavvikelserna i växel-bettet, dvs. i de åldrar då barnets tänder byts ut från mjölktänder till permanenta tänder. Korsbett innebär att överkäkens och un-derkäkens bredd inte passar ihop när man biter samman käkarna. LÄS MER

  4. 3. η Meson Production in Proton-Proton Collisions at Excess Energies of 40 and 72 MeV

    Författare :Henrik Petrén; Tord Johansson; Pawel Moskal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Elementary particle physics; Elementarpartikelfysik; Nuclear Physics; kärnfysik;

    Sammanfattning : The production of η mesons in proton-proton collisions has been studied with the WASA detector using internal pellet targets in the CELSIUS storage ring at the The Svedberg Laboratory in Uppsala. Data were taken at two beam energies, 1360 MeV and 1445 MeV, corresponding to CM excess energies of 40 and 72 MeV, respectively. LÄS MER

  5. 4. Studies on maxillary overdentures : implant- and prosthesis survival, cost analysis and patient-reported outcomes

    Författare :Peyman Ghiasi; Christel Larsson; Bruno Chrcanovic; Sofia Petrén; Victoria Franke Stenport; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prosthodontic; Dental Implants; Dental Prosthesis; Implant-Supported overdenture; cost analysis; Maxilla; Prosthesis Failure;

    Sammanfattning : Edentulism is a debilitating condition which may negatively affect quality of life, particularly in relation to nutritional and social health, speech, and poor facial appearance. Prosthetic options available range from conventional complete dentures to implant-supported overdentures (ISODs) and implant-supported full arch fixed partial dentures (ISFAFDPs). LÄS MER

  7. 5. "Socialt problem" eller "Som andra och i gemenskap med andra" : Föreställningar om människor med utvecklingsstörning

    Författare :Kerstin Färm; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mental retardation; mental handicap; social construction of mental handicaps; institutionalization; integration-segregation of handicapped; discourse and mental handicaps; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The background of the present study is an interest in how human capacities and limitations have been perceived during the 20th century in Sweden. The empirical work concemes the discursive constitution of the needs and resources of people who have been considered mentally handicapped. LÄS MER
