    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element modelling; alternative load paths; cross laminated timber; progressive collapse; CT scanning; fibre reconstruction; image analysis; Träteknik; Wood Science and Engineering;

    Sammanfattning : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. LÄS MER

  3. 2. European Banks and the Rise of International Finance after Bretton Woods (1973–1982)

    Författare :Carlo Edoardo Altamura; Mats Larsson; Richard Roberts; Uppsala universitet; []
    Nyckelord :Commercial banks; Euromarket; Financialisation; Oil Crisis; Petrodollars; Ekonomisk historia; Economic History;

    Sammanfattning : The 1970s is a crucial decade for understanding the modern financial landscape but it is still relatively unexplored in financial history. It was marked by the end of the Bretton Woods regime, the gradual liberalisation of finance, the return of banking crises and two massive energy crises. LÄS MER

  4. 3. Nerve lesions in pharynx : an aetiology of obstructive sleep apnoea

    Författare :Danielle Friberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : "Heavy snorers disease" is defined as the progression from habitual snoring to obstructive sleep apnoea (OSA). Apart from a significant weight gain, the aetiology underlying progression to a collapse of the upper airways during inspiration and sleep remains unclear. LÄS MER

  5. 4. Concrete flat slabs and footings : Design method for punching and detailing for ductility

    Författare :Carl Erik Broms; Håkan Sundquist; Mikael Hallgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; bent-down bars; building codes; cyclic loading; deflection; ductility; earthquake; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : Simple but still realistic physical models suitable for structural design of flat concrete plates and column footings with respect to punching are presented. Punching of a flat plate is assumed to occur when the concrete compression strain at the column edge due to the bending moment in the slab reaches a critical value that is considerably lower than the generally accepted ultimate compression strain 0.

  7. 5. Characterization of cochlear degeneration in the inner ear of the German waltzing guinea pig : a morphological, cellular, and molecular study

    Författare :Zhe Jin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cochlea; Deafness; Embryonic development; Inner ear; Melanocyte; Phenotype; Recessive genes; Recycling; Stria vascularis.;

    Sammanfattning : The German waltzing guinea pig is a new strain of animals with yet unknown gene mutation(s) displaying recessively inherited cochleovestibular impairment. The homozygous animals (gw/gw) are deaf already at birth and display Wpical waltzing behavior throughout life. LÄS MER
