  1. 1. Volatile organic compounds from microorganisms : identification and health effects

    Författare :Anna-Sara Claeson; Anna-Lena Sunesson; Jan-Olof Levin; Steven Nordin; Bengt Järvholm; Charles Weschler; Umeå universitet; []
    Nyckelord :microorganisms; building materials; VOCs; MVOCs; amines; LC-MS MS; exposure; perceived air quality; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Damp building materials are subjected to degradation processes due to moisture and also microbial growth, with both of these giving rise to emissions of volatile organic compounds (VOCs) that may contribute to indoor air health problems. The overall aim of this thesis was to investigate emissions of reactive and non-reactive VOCs from damp building materials and from the microorganisms growing on them, and also to investigate the possible health impact of these compounds.

  3. 2. Air pollution and dementia in a low exposure setting : the role of noise, olfaction, and theapoe gene

    Författare :John Andersson; Maria Nordin; Anna Oudin; Anna Sundström; Tom Russ; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Air pollution; Road traffic; NOx; dementia; APOE; Alzheimer’s disease; Apolipoprotein E; olfaction; particulate matter; vascular dementia; odor identification; odor detection; Psychology; psykologi;

    Sammanfattning : Previous research indicates an association between air pollution exposure, and risk of dementia. Still, a number of factors that may play a role in this association remain to be explored. LÄS MER

  4. 3. Patient safety culture in hospital settings : Measurements, health care staff perceptions and suggestions for improvement

    Författare :Anna Nordin; Kersti Theander; Bodil Wilde-Larsson; Gun Nordström; Anne-Marie Boström; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; patient safety culture; S-HSOPSC; HSOPSC; psychometric testing; managers; health care staff; nursing; S-HSOPSC; patientsäkerhetskultur; psykometri; organisation; sjukvård; Nursing Science; Omvårdnad;

    Sammanfattning : The aim was to psychometrically test the S-HSOPSC and HSOPSC, investigate health care staff’s perceptions of patient safety culture and their suggestions for improvement.Methods: A three-time cross-sectional study with data from health care staff (N= 3721) in a Swedish county council was conducted in 2009 (N = 1,023), 2011 (N = 1,228) and 2013 (N =1,470) using the S-HSOPSC (I, II, III).

  5. 4. Matematiska argument i helklassdiskussioner : En studie av elevers och lärares multimodala kommunikation i matematik i åk 3-5

    Författare :Anna-Karin Nordin; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematical arguments; reasoning; argumentation; multimodality; classroom communication; matematikämnets didaktik; Mathematics Education;

    Sammanfattning : This study aimed at investigating and analysing the communication occurring during whole class discussions, with a specific focus on the nature of the mathematical arguments. The investigation was a qualitative case study where the communication during eight whole class discussions in grade 3-5 were analysed. LÄS MER

  7. 5. Process Design for Ultrafiltration of Complex Process Streams

    Författare :Anna-Karin Nordin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bleach plant effluent; Ultrafiltration; process design; optimization;

    Sammanfattning : Considerable effort has been dedicated over the years to model and simulate the ultrafiltration process. Most approaches are theoretical and therefore not applicable to industrial process streams. When treating such solutions, a combination of experiments and simulations is needed. LÄS MER
