    Abstract : Icke-avgasemissioner av PM10 är ett problem i urbana miljöer länkat till flera hälsoaspekter. Dessa emissioner kan relateras till beläggningars egenskaper. Även resuspension av vägdamm från ytor är av betydelse och beror på både trafiken och meterologin. READ MORE

  2. 2. ON THE EFFICIENCY OF DISPLACEMENT VENTILATION, with Particular Reference to the Influence of Human Physical Activity

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Magnus Mattsson; Högskolan i Gävle.; KTH.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; Engineering mechanics Fluid mechanics; Teknisk mekanik Strömningsmekanik; Displacement ventilation; Ventilation efficiency; Physical activity; Human activity; Movements; Transient behaviours; Ceiling height; Wall temperature.;

    Abstract : The efficiency of room ventilation by the displacement principle was studied with respect to some influential factors, in particular that of physical activity. The study was experimental and performed in two full-scale test rooms, one of office-size and one of classroom-size. READ MORE

    Abstract : Selective serotonin re-uptake inhibitors (SSRIs) are a class of anxiolytic and anti-depressant drugs. SSRIs act on the evolutionarily ancient serotonergic system which is virtually identical throughout the vertebrate phylum. READ MORE

  4. 4. Microclimate measurements in the built environment

    University dissertation from Institutionen för byggd miljö

    Author : Peter Norberg; KTH.; [1998]
    Keywords : ;

    Abstract : Surface moisture plays an important role in thedeterioration of building surfaces. The extent and duration ofsurface moisture is generally impossible to predictfrommeteorological data and consequently direct measurement ofthis quantity is essential,e.g. using the WETCORR method.

    Abstract : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.
