  1. 21. Animating soils : geoarchaeological approaches to past human-environment relationships in the Arctic

    Författare :Philip Jerand; Johan Linderholm; Philip I. Buckland; Carl-Gösta Ojala; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; environmental archaeology; sampling; Sámi archaeology; spatial organisation; Arctic archaeology; geoarchaeology; soil formation; historical archaeology; miljöarkeologi; provtagning; samisk arkeologi; rumslig organisering; Arktisk arkeologi; geoarkeologi; jordmånsbildning; historisk arkeologi; Archaeology; arkeologi; environmental archaeology; miljöarkeologi;

    Sammanfattning : In this thesis, soils and sediments have been used as sources of information on past human activity in Arctic environments. The study has combined geoarchaeological methods and techniques with information from historical documents, ethnographic accounts, and archaeological remains to create integrated narratives of human-landscape interactions in the past.

  3. 22. Modeling and simulation of intrinsically disordered proteins

    Författare :Joao Henriques; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

    Sammanfattning : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. LÄS MER

  4. 23. Development and Validation of Bioanalytical Methods : Application to Melatonin and Selected Anti-Infective Drugs

    Författare :Susanne Römsing; Yngve Bergqvist; Åsa Emmer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; african trypanosomiasis; melatonin; malaria; antiretroviral drugs; lumefantrine; tafenoquine; lamivudine; nevirapine; zidovudine; sampling paper; dried blood spots; capillary blood; antimalarial drugs; solid-phase extraction; liquid chromatography; Chemistry; Kemi; Analytical Chemistry; Analytisk kemi;

    Sammanfattning : This thesis describes bioanalytical methods for measuring melatonin and some anti-infective drugs in biological fluids. Solid-phase extraction (SPE) or protein precipitation was used for enrichment and purification of the analytes and Liquid Chromatography (LC) was used to analyze the samples. LÄS MER

  5. 24. Self-sampling by elderly women for the detection of HPV and cervical dysplasia

    Författare :Ruth S. Hermansson; Matts Olovsson; Christer Borgfeldt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; self-sampling; cervical dysplasia; elderly women.; Hälso- och sjukvårdsforskning; Health Care Research;

    Sammanfattning : In Sweden, about 30% of the cervical cancer cases occur in women older than 60 and the mortality rate is as high as about 70% in this age group. There is a lack of knowledge concerning the prevalence of infection with oncogenic types of HPV, and cervical dysplasia in women of 60 years and older. LÄS MER

  7. 25. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols

    Författare :Yvonne Nordqvist; Ulrika Nilsson; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cylindrical denuder; Diisocyanate; TDI; HDI; IPDI; MDI; Chemosorption; Vapour particle distribution; Aerosol sampling; Analytical chemistry; Analytisk kemi;

    Sammanfattning : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. LÄS MER
