  1. 21. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

    Författare :Björn Sundström; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

    Sammanfattning : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. LÄS MER

  3. 22. Stiffness and aneurysm of the aorta. Relations to vascular aging, hyperglycemia, and inflammation

    Författare :Soumia Taimour; Vaskulära sjukdomar - kliniska studier; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stiffness; Hyperglycaemia; abdominal aortic aneurysm AAA ;

    Sammanfattning : A well-functioning arterial system for the transport of oxygen to the cells is essential for human health. The aorta has a key role for the provision of this physiological effect. Disturbances to aortic function can lead to majorsymptoms and even death due to ruptured abdominal aortic aneurysm (AAA).

  4. 23. Analysis of drying wood based on nondestructive measurements and numerical tools

    Författare :Jonas Danvind; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

    Sammanfattning : Improved understanding of moisture and mechanical behaviour is a general objective for wood drying research. The main objective of this doctoral thesis was to develop nondestructive experimental methods suitable for collecting valuable response data related to the moisture behaviour and mechanical behaviour of drying wood and to refine this information into modelling parameters.

  5. 24. Modeling of biomembranes: from computational toxicology to simulations of neurodegenerative diseases

    Författare :Inna Ermilova; Alexander Lyubartsev; Marta Pasenkiewicz-Gierula; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomembranes; lipid bilayers; Alzheimer s disease; Parkinson disease; computational toxicology; passive diffusion; hydroxylated polybrominated diphenyl ethers; omega-3; omega-6; amyloid beta peptide; molecular dynamics simulations; SLipids force field; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : It was known from the middle of the last century that a cell-membrane is a lipid bilayer. Since that time a large number of experimental studies has been done in order to see how a certain molecule can penetrate through a membrane. LÄS MER

  7. 25. Numerical modelling of sound propagation to closed urban courtyards

    Författare :Maarten Hornikx; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; courtyard; urban noise abatement schemes; pseudospectral; road traffic noise; equivalent sources method; scale model study; urban canyon;

    Sammanfattning : Because modern urban environments suffer from excessive levels of road traffic noise, access to closed courtyards is essential in order to offer urban sound environments of high quality with regard to health and perceived sound. To reach this quality, which is described by the quiet side definition, the 24-hour equivalent noise level should be below 45 dB(A). LÄS MER
