  2. 1. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    Author : Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

    Author : Eva Frühwald; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

    Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

  5. 3. Preharvest Conditions Affecting Apple Quality, Antioxidant Responses and Susceptibility to the Infection by Grey mould (Botrytis cinerea)

    Author : Tuyet Bui Thi Anh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malus x domestica; grey mould; preharvest weather; apples’ quality; antioxidants; harvest year;

    Abstract : Apple fruits are rich in vitamin C and other antioxidants, which are beneficial for human health. During postharvest storage, there are losses as a result of diseases such as grey mould, caused by the fungus Botrytis cinerea. The present work has investigated how to obtain a high quality of apples, allowing long-term storage. READ MORE

  6. 4. Problems in the Aluminium DC Casting Process Associated with Melt Treatment Operations

    Author : Ghadir Razaz; Torbjörn Carlberg; Arne.K Dahle; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The quality of DC cast Al alloys is highly dependent on melt batch composition and impurity level in the molten alloy. The chemical composition and cleanliness of a melt is controlled through the melt treatment operations, carried out while the melt is still in the furnace before casting starts. READ MORE

  7. 5. Enhancing UV protection of clear coated exterior wood by reactive UV absorber and epoxy functional vegetable oil

    Author : Sara Olsson; Mats Johansson; Gilles Sèbe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Since ancient times wood has played a large role in human activities, both in terms of fuel and for construction purposes. A drawback with wood in exterior applications is, however, its susceptibility to photo-initiated degradation, caused by radiation from the sun. READ MORE
