  1. 1. Organic carbon dynamics in the Baltic Sea : A modelling perspective

    Författare :Filippa Fransner; Jonas Nycander; Christoph Humborg; Andreas Oschlies; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon cycle; organic carbon; primary production; remineralisation; terrestrial DOC; extracellular DOC; flexible stoichiometry; Redfield ratio; air-sea CO2 exchange; pCO2; coupled 3D physical-biogeochemical modelling; Gulf of Bothnia; Baltic Sea; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Coastal seas constitute a link between land and the open ocean, and therefore play an important role in the global carbon cycle. Large amounts of carbon, of both terrestrial and marine origin, transit and are transformed in these waters, which belong to the more productive areas of the oceans. LÄS MER

  3. 2. Flagellates in the marine microbial food web : the ecology of a mixotrophic nanoflagellate, Ochromonas sp

    Författare :Agneta Andersson-Nordström; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbial food web; flagellates; Ochromonas sp.; mixotrophy; size- selective grazing; remineralisation; excretion of DFAA;

    Sammanfattning : Nanoflagellates were found to be abundant in a coastal area of the northern Bothnian Sea. The maximum concentration of nanoflagellates, approximately 8000 cells ml-1, was observed in July, coinciding with a decrease in the abundance of cyanobacteria. LÄS MER

  4. 3. Submicron Calcium Phosphate Spheres for Biomedical Applications : Synthesis and Use

    Författare :Tao Qin; Håkan Engqvist; Fredrik Nikolajeff; Jie Huang; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Sammanfattning : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. LÄS MER

  5. 4. The Baltic Sea Wave Field : Impacts on the Sediment and Biogeochemistry

    Författare :Anette Jönsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; HYPAS; Wave modelling; Significant wave height; Wave energy; Vattenteknik; Water engineering; Vattenteknik;

    Sammanfattning : The wave field in the Baltic Sea has been modelled for a two-year period with the spectral wave model HYPAS. There is a large seasonal variation in the field and a minor annual one, both reflect the wind variation in the area. Since the Baltic Sea is fetch limited, the dominant wind direction is important for the maximum wave heights. LÄS MER

  7. 5. Optical based technologies for detection of dental caries

    Författare :Lena Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: A conservative, non-invasive or minimally invasive approach to clinical management of dental caries requires diagnostic techniques capable of detecting and quantifying lesions at an early stage, when progression can be arrested or reversed. Objective evidence of initiation of the disease can be detected in the form of distinct changes in the optical properties of the affected tooth structure. LÄS MER
