  1. 6. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

    Författare :Anders Halldin; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

    Sammanfattning : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. LÄS MER

  3. 7. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

    Författare :Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

    Sammanfattning : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. LÄS MER

  4. 8. Moisture Induced Stresses in Timber Structures

    Författare :Johan Jönsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; load carrying capacity; Technological sciences; reinforcement; short-term strength perpendicular to grain; internal stresses; glulam; contact free measuring technique moisture gradients;

    Sammanfattning : Wood is a hygroscopic material; always striving to reach equilibrium with the surrounding air, and consequently the moisture content is different in different climate conditions. The strength of wood is directly dependent on the moisture content, lower moisture content leads to increasing strength. LÄS MER

  5. 9. Evaluation of reverse transcriptase assay for viral load monitoring

    Författare :Gary E Corrigan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Retaining an active reverse transcriptase (RT) enzyme is a fundamental requirement for all retroviruses to replicate. Bearing in mind that HIV has a very high propensity to mutate measuring RT activity to determine the level of retroviral replication has the capacity to eliminate problems associated with divergence, as the virus at all costs must retain an active RT enzyme.

  7. 10. On the long-term behaviour of tension loaded piles in natural soft soils

    Författare :Jorge Yannie; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

    Sammanfattning : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. LÄS MER
