1. 1. Policy, Interest and Power : Studies in Strategies of Research Utilization

   Författare :Kjell Nilsson; Socialhögskolan; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Expertise; Knowledge; Policy Sector; Research Utilization; Scientification; Utilization Function; Utilization Context; Utilization Strategy; sociology; social work;

   Sammanfattning : This dissertation about the utilization of applied social science is based on studies of research use in three different policy sectors - the social service, the building, and the working life sectors. In these studies some characteristics of the different policy sectors, like the distribution and exercise of power and control, was found to play a fundamental role in forming the patterns of research utilization of the organizations in the field and the ways organizations act in relation to their environments.

3. 2. Kinematics and fixation of total knee arthroplasties : a clinical, radiographic, scintimetric, and roentgen stereophotogrammetric evaluation

   Författare :Kjell G. Nilsson; Johan Kärrholm; Leif Ryd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total knee arthroplasty; tibial component; kinematics; micromotion; loosening; scintimetry; roentgen stereophotogrammetric analysis;

   Sammanfattning : Aseptic loosening of the tibial component is an important cause of failure after total knee arthroplasty. Bone destruction often claimed to be caused by the cement makes the revision difficult. In order to treat younger patients, uncemented fixation has been introduced, but the etiology to loosening is multifactorial and only partly known. LÄS MER

4. 3. Ledarskap i kris, kaos och omställning : En empirisk studie av chefer i företag och förvaltning

   Författare :Iréne Lind Nilsson; Kjell Granström; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; Pedagogik; Education; Pedagogik; pedagogik; Education;

   Sammanfattning : Over the past years, organizations have now and again found themselves in situations characterized by crisis, chaos, and change. These situations are the result, among other things, of social changes like technological developments, internationalization, fluctuating economies, and shifts in values. LÄS MER

5. 4. A ΔJ approach for nonlinear fatigue crack propagation : Experimental and numerical investigation of a ductile superalloy

   Författare :Daniel Nilsson; Per Almroth; Kjell Simonsson; Björn Sjödin; Daniel Leidermark; Sören Sjöström; Fredrik Borén; Johan Ahlström; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ΔJ; Cyclic J-integral; Fatigue testing; Nickel-based superalloy; Thermo-mechanical fatigue; Elasto-plastic fracture mechanics;

   Sammanfattning : This dissertation is a product of an academic-industrial collaboration between the Division of Solid Mechanics at Linköping University and Siemens Energy AB. The focus is on enhancing the design optimisation procedures for high-temperature components in industrial gas turbines (IGT). LÄS MER

7. 5. Kemistudenters föreställningar om entalpi och relaterade begrepp

   Författare :Tor Nilsson; Hans Niedderer; Kjell Waltersson; Roland Kjellander; Mälardalens högskola; []
   Nyckelord :enthalpy; thermodynamics; chemistry; chemistry education; conceptions; higher education; entalpi; termodynamik; kemi; kemididaktik; ämnesdidaktik; föreställningar; begrepp; begreppsbildning; högre utbildning; naturvetenskapernas och teknikens didaktik; naturvetenskapernas och teknikens didaktik;

   Sammanfattning : The aim of this thesis was to construct undergraduate chemistry students’ conceptions of enthalpy and its change, internal energy and its change, heat and work. Conceptions make it possible to identify students’ problems with the taught content. How students’ exam results are affected by qualitative/conceptual questions was also investigated. LÄS MER
