    Författare :Karin Engvall; Dan Norbäck; Eva Sandstedt; Göran Strid; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Indoor environment; Questionnaire; Atopy; Building age; Indoor air quality; Sick building syndrome SBS ; Validation; Dwelling; Energy conservation; Mechanical ventilation; Building dampness; Building reconstruction; Wood heating; Electric heating; Heat pump; Thermal Insulation; Sealing; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. LÄS MER

  3. 2. Indoor Environment in Dwellings and Sick Building Syndrome (SBS) : Longitudinal Studies

    Författare :Bo Sahlberg; Dan Norbäck; Berndt Stenberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Indoor environment; sick building syndrome SBS ; dwelling; longitudinal cohort study; building dampness; mould; microbial volatile organic compounds MVOC ; biomarkers; asthma; risk factors; Arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : People spend most of their time indoors and mostly in the dwelling. It is therefore important to investigate associations between indoor exposure in dwellings and health. Symptoms that may be related to the indoor environment are sometimes referred to as the "sick building syndrome" (SBS). LÄS MER

  4. 3. Scaling Indoor Positioning : improving accuracy and privacy of indoor positioning

    Författare :Jimmy Engström; Jan A. Persson; Åse Jevinger; Carl Magnus Olsson; Gustaf Hendeby; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Our phones have many uses for positioning technologies, such as navigation, LocationBased Services (LBS), emergency positioning, fitness applications, and advertising. We trust our phones and wearables to be location-aware. LÄS MER

  5. 4. Oxidation of terpenes in indoor environments : A study of influencing factors

    Författare :Linda Pommer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Monoterpene; Ozone O3 ; Nitrogen dioxide NO2 ; Nitrogen oxide NO ; Relative humidity RH ; Modelling; Scrubber; Experimental design; Interaction; Volatile organic compounds VOC ; Sick buildings syndrome SBS ; Principal component analysis PCA ; Indoor air; Ventilation; Tenax TA; Sodium sulphite; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : In this thesis the oxidation of monoterpenes by O3 and NO2 and factors that influenced the oxidation were studied. In the environment both ozone (O3) and nitrogen dioxide (NO2) are present as oxidising gases, which causes sampling artefacts when using Tenax TA as an adsorbent to sample organic compounds in the air.

  7. 5. Indoor Environmental Factors and Chronic Diseases in Swedish Pre-School Children : Risk factors and methodological issues investigated in a longitudinal study on airway diseases and autism spectrum disorder

    Författare :Malin Larsson; Carl-Gustaf Bornehag; Staffan Janson; Gunilla Wieslander; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; rhinitis; eczema; autism spectrum disorder; indoor environment; moisture related problems; chemical exposure; methodological issues; Public health science; Folkhälsovetenskap; Public Health Science; Folkhälsovetenskap;

    Sammanfattning : Asthma and allergies have increased considerably during the past 40-50 years. Along with this increase, a heightened awareness regarding different neuro-developmental disorders such as autism spectrum disorder has occurred and it has been proposed that such disorders are also on the increase.
