  1. 36. Systematic design of glulam trusses

    Författare :Helena Johnsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The design of a structure should be regarded as the design of a system. In this licentiate thesis a method (concurrent engineering) for the design of systems is studied parallel with the development of the system itself. LÄS MER

  3. 37. Resistance of polygonal cross-sections : application on steel towers for wind turbines

    Författare :Olga Garzon; Carlos Alberto da Silva Rebelo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Wind power is considered an efficient alternative for production of electrical energy. One advantage that wind power offers compared to conventional ways of producing energy such as fossil energy and nuclear energy is the low emission of carbon dioxide “CO2” during production of electrical energy.

  4. 38. Computational Studies of Nitrogenase

    Författare :Lili Cao; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogenase; QM MM; quantum refinement; FeMo cluster; E4 state; N2 binding; V-nitrogenase; P-cluster; S2B dissociation; broken-symmetry state; homocitrate; DFT; protonation state; disorder; ComQumX-2QM;

    Sammanfattning : AbstractNitrogenase is the only enzyme that can convert the inert nitrogen molecule to ammonia, so that it can be used for biomass production and in biosynthetic pathways. It contains a complicated acitve site, composed of eight metal ions, nine sulfur ions and one carbide ion (the FeMo cluster). LÄS MER

  5. 39. Condition monitoring of railway vehicles : a study on wheel condition for heavy haul rolling stock

    Författare :Mikael Palo; Thomas Robertsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : A railway is an energy efficient mode of transport as it uses the low resistance contact between wheel and rail. This contact is not frictionless and causes wear on both surfaces. The wheel-rail guidance is made possible by the shapes of wheel and rail profiles. LÄS MER

  7. 40. Produktion, produktivitet och kostnader i svensk tandvård

    Författare :Ingvar Westerberg; Bengt Jönsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public dental care; Private dental care; Productivity; Production function; Economic systems; Tandläkare; Tandvård; Tandvårdskostnader;

    Sammanfattning : The thesis contains projects at a national as well as a clinical level.On a national level a study is made of productivity in adult dental care in both its private and its public·sectors. LÄS MER
