    Sammanfattning : Today, the growing and aging population, and the rise of new global threats on human health puts an increasing demand on the healthcare system and calls for preventive actions. To make existing medical treatments more efficient and widely accessible and to prevent the emergence of new threats such as drug-resistant bacteria, improved diagnostic technologies are needed.

  2. 2. Export and sources of organic carbon in the Lena River basin, Northeastern Siberia

    Detta är en avhandling från Stockholm : Department of Geological Sciences, Stockholm University

    Författare :Liselott Kutscher; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; organic matter; NOM; DOM; POM; Lena River; organsikt kol; DOC; POC; organiskt material; NOM; DOM; POM; Lenafloden; geokemi; Geochemistry;

    Sammanfattning : Permafrost areas are considered to be one of the largest terrestrial storages of carbon. In a warming climate these areas are expected to experience changes in carbon transport to rivers and the oceans due to permafrost thawing, which could enhance erosion, change water flow pathways and increase greenhouse gas emissions.

  3. 3. Terrestrial organic carbon dynamics in Arctic coastal areas budgets and multiple stable isotope approaches

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM)

    Författare :Vanja Alling; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic carbon; DOC; POC; multiple stable isotopes; Laptev Sea; East Siberian Sea; Lena River; Arctic; residence times; degradation; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. LÄS MER

  4. 4. Compensating for Unreliable Communication Links in Networked Control Systems

    Detta är en avhandling från Stockholm : KTH

    Författare :Erik Henriksson; KTH.; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER

  5. 5. Interfaces in aquatic ecosystems: Implications for transport and impact of anthropogenic compounds

    Detta är en avhandling från Johannes C. Knulst, Swedish Environmental Research Institute, Aneboda, S-360 30 Lammhult, Sweden

    Författare :Johannes Knulst; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; limnology; aquatic ecology; surface microlayer; aquatic surface film; humic substances; particles; acidification; dissolved; liming; climate change; marine biology; Hydrobiology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Mechanisms that govern transport, accumulation and toxicity of persistent pollutants at interfaces in aquatic ecosystems are the foci of this thesis. Specific attention is paid to humic substances, their occurrence, composition, and role in exchange processes across interfaces. LÄS MER
