  1. 1. Critical Moisture Conditions for Mould Growth on Building Materials

    Författare :Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould; critical moisture level; building material; relative humidity; mould resistance; crawl space; attic;

    Sammanfattning : Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. LÄS MER

  3. 2. The Late etruscan votive heads from Tessennano. A study of production, distribution and sociohistorical context

    Författare :Martin Söderlind; Antikens kultur och samhällsliv; []
    Nyckelord :HUMANIORA; HUMANITIES; mould circulation; terracotta sarcophagi; Roman colonization; petrographic microscopy; Late etruscan; mould generation; mould; archetype; votive head; terracotta; traveling workshops; velum; Ancient history; Antikens och forntidens historia;

    Sammanfattning : The Late etruscan terracotta votive heads from Tessennano were found near a rural sanctuary about a hundred km to the North of Rome in 1956. Whereas the facial fronts are serially produced with moulds, the backs are handmade. LÄS MER

  4. 3. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    Författare :Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

    Sammanfattning : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. LÄS MER

  5. 4. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

  7. 5. Asthma and Rhinitis among Adults in Sweden and China : Risk Factors in the Home Environment

    Författare :Juan Wang; Dan Norbäck; Christer Janson; Karin Engvall; Tuula Putus; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rhinitis; Asthma; Home; Dampness; Mould; Ventilation; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : The main aim of this thesis was to evaluate associations between selected home environment factors and asthma, rhinitis and respiratory symptoms among adults from Sweden, China and northern Europe. Two studies were performed in Sweden, one in China, and one longitudinal cohort study was performed in northern Europe. LÄS MER
