  1. 1. Compensation for hearing loss and cancellation of acoustic feedback indigital hearing aids

    Författare :Johan Hellgren; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The development of integrated circuits during the last decades has made it possible to incorporate digital signal processing in hearing aids that fit into the ear canal and are powered by small zink-air batteries. The digital signal processing provides new possibilities for the hearing aid to modify the signal to fit the impaired ear. LÄS MER

  4. 3. Non-infectious rhinitis. Epidemiology and clinic

    Författare :Johan Hellgren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-infectious rhinitis; Paper dust; Asthma; Quality of life; Acoustic rhinometry;

    Sammanfattning : We have assessed self-reported rhinitis in the absence of common cold, called "Non-infectious rhinitis", (NIR). The occurrence of NIR was investigated in a population sample of 2,044 individuals, aged 21-51, in an industrialised county in Sweden who answered a questionnaire relating to NIR and occupational exposure to potential irritants and sensitisers.

  5. 4. A New Model for Assessment of Change in Visual Function in Diabetes

    Författare :Karl-Johan Hellgren; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetic retinopathy; visual function; perimetry;

    Sammanfattning : The purpose of this thesis was to determine whether perimetry using a new model to interpret deterioration or improvement in the visual field can be employed to assess change in visual function over time in diabetes. Diabetic retinopathy has long been considered a microvascular disease, but it is still a matter of debate to what extent diabetes also affects retinal neurons. LÄS MER

  7. 5. Att översätta TQM : - en longitudinell studie kring reflekterande aktörer

    Författare :Johan Quist; Bo Edvardsson; Bo Bergman; Bo Enquist; Bo Hellgren; Karlstads universitet; []

    Sammanfattning : This doctoral thesis focuses on translating Total Quality Management (TQM). The reason for this focus is that ideas such as TQM rarely or never contain a complete description of how the idea is to be “installed” in an organisation if it is to achieve the intended result. LÄS MER
