  1. 1. Durability of fire exposed concrete : Experimental Studies Focusing on Sti„ffness & Transport Properties

    Författare :Joakim Albrektsson; Johan Silfwerbrand; Lars Boström; Manouchehr Hassanzadeh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Fire; Polypropylene fibres; Durability; Tunnel; Damage assessment; Ultrasonic pulse velocity; Water absorption; Chloride migration; DIC; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. LÄS MER

  3. 2. Optimisation of Off-Road Transport Missions

    Författare :Jörgen Albrektsson; Jan Åslund; Lars Eriksson; Nikolce Murgovski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Mines, construction sites, road construction and quarries are examples of applications where construction equipment are used. In a production chain consisting of several construction machines working together, the work needs to be optimised and coordinated to achieve an environmental friendly, energy efficient and productive production.

  4. 3. On New Implants - The results of five prospective, randomized RSA trials with aspects on phased introduction and continuous migration

    Författare :Mats Molt; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; New total knee arthroplasty; TKA; RSA; randomized; prospective; prediction; continuously migrating; safety; stability CR; PS; PF; PA; short stem; tourniquet;

    Sammanfattning : A concern that arises with any change in design or operative technique is whether it affects the long-term implant stability or not. One way to address this is, by measuring early micromotion, to predict the future revision rate. LÄS MER

  5. 4. On the management of some technical and biological complications in implant prosthodontics

    Författare :S Luterbacher-Tschudin; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The use of osseointegrated titanium implants has become a widely accepted method to obtain retention for prosthetic reconstructions of partially dentate and edentulous patients. A range of c1inical long-term studies have been conducted to collect information on the numbers of surviving and/or successful implants for different implant systems. LÄS MER
