    Sammanfattning : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. LÄS MER

  2. 2. Cabin Air Quality in Commercial Aircraft Exposure, Symptoms and Signs

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Torsten Lindgren; Uppsala universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; airline crew; aviation medicine; micro-organism; cabin air quality; air humidity; atopy; occupational exposure; environmental tobacco smoke ETS ; psychosocial work environment; Medicin; MEDICINE Dermatology and venerology; clinical genetics; internal medicine; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. LÄS MER

  3. 3. Indoor environment and air quality in hospital units : Symptoms and signs

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Klas Nordström; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : Indoor environment may influence the occurrence of symptoms such as eye, skin and upper airway irritation, headache and fatigue. The aim of the dissertation was to study relations between subjective indoor air quality, such symptoms, clinical signs from the nose and the eyes and the physical indoor environment, in particular the effect of dampness, type of building, and air humidification.

  4. 4. Aspects on the lacrimal drainage function

    Detta är en avhandling från Stockholm : Karolinska Institutet, -

    Författare :Sven Sahlin; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The aim of this project was to increase the knowledge on the function of the lacrimal passages. For this purpose, a quantitative test for the lacrimal drainage function is established: the drop test. Two principal parameters are introduced: the lacrimal drainage capacity and the blink output.

  5. 5. Studies of electrically conductive textile coatings with PEDOT:PSS

    Detta är en avhandling från Chalmers University of Technology

    Författare :Maria Åkerfeldt; Högskolan i Borås.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Textil och mode generell ; Textiles and Fashion General ; textile coating; conductive coating; conjugated polymers; coating parameters; PEDOT:PSS; Textile technology;

    Sammanfattning : This study investigates electrically conductive coatings of textiles, obtained with a direct coating and the addition of poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) dispersion to a thickened polyurethane (PU)-based formulation. Textiles with enhanced electrical conductivity have potential applications in antistatic, electrostatic discharge protective, electromagnetic interference shielding, sensoric and temperature-regulating products.
