  1. 1. Analysis of Acoustic Absorption with Extended Liner Reaction and Grazing Flow

    Författare :Anna Färm; Mats Åbom; Lars Enghardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; acoustic lining; non-locally reacting; boundary layer; grazing flow; sound field; transfer matrix method;

    Sammanfattning : Acoustic absorbing liners are efficient and commonly used measures to reduce sound levels in many fields of application. The sound reducingperformance of the liners is dependent on the acoustic state, defined by e.g. the flow and sound field interacting with the liner. LÄS MER

  3. 2. Exploring small airways using breath analyses

    Författare :Emilia Viklund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exhaled particles; small airways; alveolar nitric oxide; SARS-CoV-2; birch pollen; smoking; lining fluid;

    Sammanfattning : Background: Airway irritants such as allergens, tobacco smoke and viruses may cause damage in the small airways, usually undetected with routine diagnostic methods. Analyses of endogenously produced nitric oxide (NO) and endogenously produced small droplets (i.e. LÄS MER

  4. 3. Functional role of cerebrospinal fluid contacting cells in the spinal cord and hypothalamus

    Författare :Elham Jalalvand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cerebrospinal fluid-contacting (CSF-c) cells are found lining the walls of the central canal and the ventricles throughout the vertebrate phylum, but their function has remained elusive. The aim here was to investigate the physiological role of CSF-c cells in the spinal cord and hypothalamus. LÄS MER

  5. 4. Clinical, immunological and olfactory aspects of sinusitis and nasal polyposis : with special reference to patients with cystic fibrosis

    Författare :Gert Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal polyposis; sinusitis; cystic fibrosis; allergy; bacteria; in-patient; interleukin-8; muramidase; nasal lavage fluid; polymerase chain reaction; Pseudomonas aeruginosa; smell; olfaction; anosmia; hyposmia; olfactory threshold test; identification smell test; germ-free animal; T-cell receptor; normal microbiota.;

    Sammanfattning : The otorhinolaryngological approach to the problem concerning rhinosinusitis and nasal polyposis in the recessive genetic disorder of cystic fibrosis (CF) has been developed based on data from international studies. Opinions differ on how to treat the otolaryngological manifestations of CF (sinusitis, nasal polyps and hyposmia). LÄS MER

  7. 5. Upper Airway Mucosal Inflammation : Proteomic Studies after Exposure to Irritants and Microbial Agents

    Författare :Louise Fornander; Mats Lindahl; Bijar Ghafouri; Pål Graff; Magnus Svartengren; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : People are, in their daily lives, exposed to a number of airborne foreign compounds that do not normally affect the body. However, depending on the nature of these compounds, dose and duration of exposure, various airway symptoms may arise. LÄS MER
