1. 1. The Nuclear Waters of the Soviet Union : Hydro-Engineering and Technocratic Culture in the Nuclear Industry

   Författare :Achim Klüppelberg; Per Högselius; Kati Lindström; Anna Storm; Melanie Arndt; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; Nuclear power; water; technocratic culture; USSR; energy system; hydro-nuclear entanglements; Atomkraft; Wasser; technokratische Kultur; Sowjetunion; Energiesystem; hydronukleare Verflechtungen; Kärnkraft; vatten; teknokratisk kultur; Sovjetunionen; energisystem; hydronukleära sammanflätningar; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

   Sammanfattning : After the development of nuclear weapons, civil applications were seen as a way through which protagonists of Soviet modernity could embrace a new future, which Josephson called atomic-powered communism. Where hydro-powered communism had reached its boundaries, nuclear energy was to take over. LÄS MER

3. 2. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

   Författare :Anders Kullingsjö; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

   Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER

4. 3. Call centre work : characteristics, physical, and psychosocial exposure, and health related outcomes

   Författare :Kerstin Norman; Håkan Alm; Ewa Wigaeus Tornqvist; Allan Toomingas; Gunnevi Sundelin; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Callcenter; fysisk och psykosocial exponering; hälsa; Work sciences and ergonomics; Arbetsvetenskap och ergonomi;

   Sammanfattning : Call centres (CCs) are one of the most rapidly growing forms of workplaces in Sweden. The overall aim of this thesis was to describe work characteristics, physical and psychosocial exposures, and health related outcomes, for CC operators in selected CC in Sweden. LÄS MER

5. 4. Theoretical modeling of molar volume and thermal expansion

   Författare :Xiao-Gang Lu; Bo Sunsman; Michel Jacobs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; first-principles calculations; ab initio; Calphad; Debye-Grüneisen model; thermodynamic properties; elastic modulus; volume; thermal expansivity; pressure; Thermo-Calc; VASP; element; carbide; nitride; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Combination of the Calphad method and theoretical calculations provides new possibilities for the study of materials science. This work is a part of the efforts within the CCT project (Centre of Computational Thermodynamics) to combine these methods to facilitate modeling and to extend the thermodynamic databases with critically assessed volume data.

7. 5. Long-term consequences of anterior cruciate ligament injury : knee function, physical activity level, physical capacity and movement pattern

   Författare :Eva Tengman; Charlotte Häger; Eva Ageberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ACL injury; cross-sectional design; isokinetic; peak torque; centre of pressure; kinematics; sjukgymnastik; Physiotherapy;

   Sammanfattning : Knee function after more than 20 years post injury is rarely described and none of the few follow-up studies have evaluated functional performance tasks. This thesis investigated self-reported knee function, physical activity level, physical capacity and movement pattern in the long-term perspective (on average 23 years) in persons who had suffered a unilateral ACL injury, treated either with physiotherapy in combination with surgery (ACLR, n=33) or physiotherapy alone (ACLPT, n=37) and compared to age-and-gender matched controls (n=33).
