  1. 1. Compositional clues to sources and sinks of terrestrial organic matter transported to the Eurasian Arctic shelf

    Författare :Emma Karlsson; Örjan Gustafsson; Volker Brüchert; Thorsten Dittmar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic carbon; degradation; microcosm; incubation; terrestrial biomarkers; acyl lipids; lignin phenols; radiocarbon; Eurasian Arctic shelf; East Siberian Sea; Laptev Sea; Lena River; colloidal matter; particulate matter; sedimentary matter; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The amount of organic carbon (OC) present in Siberian Arctic permafrost soils is estimated at twice the amount of carbon currently in the atmosphere. The shelf seas of the Arctic Ocean receive large amounts of this terrestrial OC from Eurasian Arctic rivers and from coastal erosion. LÄS MER

  2. 2. Organic geochemical investigation of sources, transport and fate of terrestrial organic matter in the southeast Laptev Sea

    Författare :Emma Karlsson; Örjan Gustafsson; Volker Brüchert; Sebastian Sobek; Rienk Smittenberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi; Marine Geoscience; marin geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Permafrost carbon stores have been suggested to react to warming trends with increased terrestrial loading to its coastal waters. Presently, the warming has been seen to be especially high in the East Siberian Arctic and the fate of the major release of terrestrial matter to these coasts is yet to be detailed. LÄS MER

  3. 3. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

    Författare :Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

    Sammanfattning : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. LÄS MER

  4. 4. System studies of biogas production : comparisons and performance

    Författare :Emma Lindkvist; Magnus Karlsson; Mats Söderström; Maria Johansson; Ola Norrman Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. LÄS MER

  5. 5. Pharmacometric Models for Biomarkers, Side Effects and Efficacy in Anticancer Drug Therapy

    Författare :Emma K. Hansson; Lena Friberg; Mats O Karlsson; Charlotte Kloft; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics; Pharmacodynamics; Oncology; Febrile Neutropenia; GIST; Sunitinib; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : New approaches quantifying the effect of treatment are needed in oncology to improve the drug development process and to enable treatment optimization for existing therapies. This thesis focuses on the development of pharmacometric models for biomarkers, side effects and efficacy in order to identify predictors of clinical response in anti-cancer drug therapy. LÄS MER
