  1. 1. Cross-scale monitoring, landscape trajectories, and feedback in forest management : Examples from southern and middle boreal ecosystems in Sweden

    Författare :Sofia Eriksson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Physical geography; Naturgeografi; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : To manage for sustainability in a complex and changing world requires understanding of the coupled human-environmental system. The two case studies in this licentiate thesis are linked by what we can learn from past and current management in the form of feedback and how it can be incorporated into practical forest management within the boreal region.

  3. 2. Genetic adaptation of salmonella enterica to phagocytic cells

    Författare :Sofia Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella; macrophages; host-adaptation; microarray; nitric oxide;

    Sammanfattning : Salmonella enterica is a collection of closely related enteric bacteria that as a species is capable of infecting a wide variety of hosts. S. enterica serovar Typhimurium, (S. Typhimurium), causes a systemic disease in mice which in many aspects resembles human typhoid fever caused by S. LÄS MER

  4. 3. Cross-scale perspectives on heterogeneity in Swedish boreal forests

    Författare :Sofia Eriksson; Monica Hammer; Helle Skånes; Risto Kalliola; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sustainable forest management; biodiversity conservation; landscape analysis; historical maps; ownership; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Sammanfattning : Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. LÄS MER

  5. 4. Histopathological and neuroimaging studies in partial epilepsy with emphasis on malformations of cortical development

    Författare :Sofia Eriksson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; epilepsy; epilepsy surgery; multiple pathology; malformations of cortical development; microdysgenesis; morphometry; diffusion tensor imaging;

    Sammanfattning : The aim of the first part of the present study was to describe the whole Göteborg epilepsy surgery series between 1987 and 1995 with respect to surgical procedures, histopathological findings and clinical correlates. We found a high proportion of malformations of cortical development (MCD) and patients with MCD were studied in further detail in the following studies. LÄS MER

  7. 5. Stable Numerical Methods with Boundary and Interface Treatment for Applications in Aerodynamics

    Författare :Sofia Eriksson; Jan Nordström; Gunilla Kreiss; Thomas Hagstrom; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; summation by parts; simultaneous approximation term; accuracy; stability; finite difference methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : In numerical simulations, problems stemming from aerodynamics pose many challenges for the method used. Some of these are addressed in this thesis, such as the fluid interacting with objects, the presence of shocks, and various types of boundary conditions. LÄS MER
