  1. 1. Metoder att välja korrektioner vid fuktberäkningar med variabelt utomhusklimat

    Författare :Eva Harderup; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture flow; Moisture; numerical modelling; calculation model; moisture distribution; non-linear moisture flow; external climate; moisture calculations; corrections; Building construction; periodic boundary condition; reference year; Byggnadsteknik;

    Sammanfattning : Determination of the design conditions for moisture resistance requires in a Moisture Design number of different moisture calculations to be made in order to determine the moisture status within, or on the surface of, a structure. The objective of this work has been to ascertain how to allow for variations in climate data in order to be able to determine the most unfavourable moisture status likely to be encountered during the life of a building.

  3. 2. Moisture content profiles and surface phenomena during drying of wood

    Författare :Anders Rosenkilde; KTH; []
    Nyckelord :computer tomography; diffusion; magnetic resonance; moisture measurement; moisture profiles; surface emission; wood drying;

    Sammanfattning : Timber drying is one of the most important processes whenmanufacturing sawn timber products. The drying processinfluences deformations, surface checking, discoloration andhence, the product quality and the manufacturing costs. LÄS MER

  4. 3. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Sammanfattning : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. LÄS MER

  5. 4. On Sahelian-Sudan rainfall and its moisture sources

    Författare :Abubakr A. M. Salih; Qiong Zhang; Michael Tjernström; Alessandra Giannini; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sudan; Sahel; rainfall; land use; deforestation; moisture sources; moisture transport; Lagrangian; moisture tagging; regional model; climate modeling; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The African Sahel is one of the most vulnerable regions to climate variability at different time scales. It is an arid to semi-arid region with limited water resources. The summer rainfall is one of these sources, but it exhibits pronounced interannual variability. This thesis presents several aspects of Sahelian Sudan rainfall. LÄS MER

  7. 5. Surface-Densified Wood : From Laboratory-Scale Research Towards a Competitive Product

    Författare :Benedikt Neyses; Dick Sandberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : For many decades, humans have been consuming more resources than the world has to offer in the long run. Increasing the use of renewable materials, such as wood, is essential if we are to achieve a sustainable use of the resources available to us. LÄS MER
