  1. 21. Aerosol-Cloud-Precipitation Interactions - Studied using combinations of remote sensing and in-situ data

    Författare :Moa Sporre; Ergonomi och aerosolteknologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; clouds; aerosol particles; climate; precipitation; satellite data; Fysicumarkivet A:2016:Sporre;

    Sammanfattning : Cloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. LÄS MER

  3. 22. MEMS Interfaces for Bioanalysis Systems

    Författare :Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

    Sammanfattning : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. LÄS MER

  4. 23. Experimental and Clinical Studies of SLPI, with Special Reference to IgE-Mediated Allergic Reactions

    Författare :Ulla Westin; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in situ hybridisation; immunohistochemistry; allergic rhinitis; atopic subjects; IgE-mediated histamine release; mast cell proteases; plasma protease inhibitors; SLPI; human leukocyte proteases; Immunology; serology; transplantation; Immunologi; serologi;

    Sammanfattning : In this study we demonstrated the production of SLPI (Secretory Leukocyte Protease Inhibitor) in serous glands in the nasal mucosa. We have shown that the pattern of the expression of mRNA corresponds to the encoded protein. The encoded protein was detected by immunohistochemical methods and mRNA was discovered by in situ hybridisation. LÄS MER

  5. 24. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

    Författare :Anja Enell; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Naturvetenskap; Chemical technology and engineering; Natural science; Miljöstudier; Environmental studies; coal tar; PAHs; desorption; soil; combustion residues; remediation; availability;

    Sammanfattning : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.
