1. 6. Calorimetric methods for the study of fungi on building materials

   Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

   Sammanfattning : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. LÄS MER

3. 7. Simulation of historic buildings for enhancement of preservation and energy performance – issues and methods

   Författare :Torun Widström; Folke Björk; Kjartan Gudmundsson; Jesper Arfvidsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building simulation; historic buildings; energy performance; damage risk; mould; thermal bridges; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Historic buildings are often particularly poorly insulated and difficult to heat, and are also at risk for several reasons. These include potential lack of use due to low thermal comfort leading to low or no profitability, damage risks due to over and under-climatization and risks due to climate change altering the boundary conditions that they were built for.

4. 8. The indoor environment in schools : Respiratory effects and air quality

   Författare :Greta Smedje; Uppsala universitet; []
   Nyckelord :Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

   Sammanfattning : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.

5. 9. Tooling and processing for efficient and high tolerance prepreg composite manufacturing

   Författare :Tommy Grankäll; Malin Åkermo; Per Hallander; Simon Bickerton; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tooling; Composite Manufacturing; Mould; Cure tool; Hot-forming; Compensation; Moisture; Shape distortion; Flyg- och rymdteknik; Aerospace Engineering;

   Sammanfattning : Composite use is normally motivated in aircraft design by improved weight-specific mechanical properties as compared to metals. However, fatigue and dielectric properties may also be critical for material selection. LÄS MER

7. 10. 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
