  1. 1. Mark i marginalen : Drivkrafter, pionjärer och myrodlingslandskap

    Författare :Annika Strandin Pers; Mats Widgren; Ulf Jansson; Tom Mels; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; historical geography; mires reclamation; landscape; Sweden; early modern period; labour migrations; international relations; discourse; practice; mobility; knowledge and skills development; kulturgeografi; Human Geography;

    Sammanfattning : This thesis investigates the reclamation of mires (fens and bogs) in Sweden with a focus on the early modern period. Today, the mires are valued natural habitats and their cultivation is controversial. International research describes wetland reclamation and the related knowledge transfer between European countries already from the 12th century. LÄS MER

  3. 2. Carbon Dynamics in Northern Marginal Seas

    Författare :Sofia Hjalmarsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved inorganic carbon; total alkalinity; continental shelf pump; marginal seas; Baltic Sea; Skagerrak; Laptev Sea; East Siberian Sea; Chukchi Sea;

    Sammanfattning : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. LÄS MER

  4. 3. Marginal cost pricing of electricity

    Författare :Göran Edsbäcker; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The discipline is economics and the phenomenon is the power system. The purpose of this system is to produce, transmit and consume electricity in such a way that the sum of consumers' and suppliers' surplus is maximized. This is accomplished by the means of marginal cost pricing. LÄS MER

  5. 4. Graph-structured multi-marginal optimal transport : Theory, applications, and efficient methods using entropy regularization

    Författare :Isabel Haasler; Johan Karlsson; Michele Pavon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Optimization and Systems Theory; Optimeringslära och systemteori;

    Sammanfattning : This thesis deals with a class of multi-marginal optimal transport problems, which we call graph-structured multi-marginal optimal transport. The aim of the thesis is to work towards a unified framework for this class of problems. The included papers explore theoretical, computational, and practical aspects of the novel framework, e.g. LÄS MER

  7. 5. Healing of marginal defects around implants

    Författare :Daniele Botticelli; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The purpose of the present series of investigations was to study the healing of marginal defects around implants. The hard-tissue alterations following immediate implant placement in extrac-tion sites were analyzed in 18 patients (study I). LÄS MER
