  1. 11. Aiway Mucins: experimental models for studies of secretions

    Författare :Naila Svitacheva; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cystic fibrosis; bovine trachea; radiolabelling; cell line; primary cell culture; organ culture; mucus; mucin; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Mucins are essential components of the mucosal barrier. The complexity of the airway mucosal barrier is reflected in the lack of specific treatments to block mucin hypersecretion associated with several respiratory diseases such as chronic bronchitis, asthma and cystic fibrosis.

  3. 12. Studies on the alpha-recoil implantation of 214Pb and 210Pb in glass surfaces,Implications for retrospective radon measurements

    Författare :Birgitta Roos; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unattached activity; attached activity; retrospective radon measurement; long-lived radon progenies; short-lived radon progenies; deposition velocity; implantation; 222Rn; glass surface; etching; simulation; Nuclear physics; Kärnfysik;

    Sammanfattning : Glass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. LÄS MER

  4. 13. Experimental Studies on Ambient Aerosol Hygroscopicity

    Författare :Erik Fors; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Fors;

    Sammanfattning : The air around us is full of aerosol particles which originate from a myriad of sources and which have vastly different chemical and physical properties. These particles span size ranges from 1 nm to 100 μm, equivalent to a factor 100 000 in diameter difference and a factor 10^15 in volume difference. LÄS MER
