1. 1. Long-term Effects of Opioids in the Treatment of Chronic Pain : Investigation of Problems and Hazards on Clinical, Biochemical, Cellular and Genetic Levels

   Författare :Annica Rhodin; Torsten Gordh; Fred Nyberg; Mats Stridsberg; Mats Enlund; Harald Breivik; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; opioid; chonic pain; long-term opioid treatment; Anaesthetics; Anestesiologi; Anestesiologi; Anaesthesiology;

   Sammanfattning : After two decades of liberal prescribing of opioids, there has been an increasing recognition of problems connected to the prolonged use of opioids for chronic pain. The aim of my thesis was to explore some consequences of long-term opioid treatment for chronic pain such as problematic opioid use, endocrine disorders, tolerance and genetic variations in pain and opioid response.

3. 2. CFD of Duct Acoustics for Turbocharger Applications

   Författare :Emma Alenius; Mats Åbom; Laszlo Fuchs; Federico Piscaglia; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aero acoustics; Large Eddy Simulation; IC-engines; 1D models; turbocharger; orifice plate; Acoustics; Akustik; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. In this work the main focus is the turbocharger compressor and a discussion of turbocharger acoustics and earlier work within the area is presented, giving an insight into its sound generating mechanisms and the damping effect it has on pressure pulses, i.

4. 3. Gluten Protein-Based Microcellular Foams and Composites: Development and Functional Properties

   Författare :Thomas Blomfeldt; Mikael Hedenqvist; Mats K G Johansson; Lars Kloo; KTH; []
   Nyckelord :Wheat Gluten; Foam; Freeze-drying; Glycerol; Bacterial cellulose; Pore structure; Protein structure; Compression; Thermal conductivity; Combustion;

   Sammanfattning : Most common foams are produced from non-renewable resources (e.g., synthetic plastics),with a number of environmental concerns, hence there is a demand for alternative bio-derivedfoam materials. Wheat gluten protein is widely known to have excellent foaming properties(e. LÄS MER

5. 4. Industrial Phantasmagoria : Subcultural Interactive Cinema Meets Mass-Cultural Media of Simulation

   Författare :Mikolaj Dymek; Mats Engwall; Claes Gustafsson; Alf Rehn; Saara Taalas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; video game industry; computer game industry; video games; computer games; cultural industries; media industries; cultural economy; game studies; literary theory; ludology; narratology; interactive cinema; simulational media; ergodic literature; cybertext; interactive narrative; business studies; industrial economy; hardcore gaming; casual gaming; subcultural industries; Industrial engineering and economy; Industriell teknik och ekonomi;

   Sammanfattning : The video game industry has in three decades gone from a garage hobby to a global multi-billion euro media industry that challenges the significantly older and established cultural industries. After decades of explosive growth the industry surprisingly finds itself in a crisis – in terms of sales, future trajectories and creative paradigms. LÄS MER

7. 5. Lipase-Catalyzed Syntheses of Telechelic Polyesters

   Författare :Magnus Eriksson; Karl Hult; Mats Martinelle; Sergio Riva; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Candida antarctica lipase B; lipase-catalysis; polymerization; telechelic; functional polyesters; ring-opening polymerization; polycondensation.; Biochemistry; Biokemi;

   Sammanfattning : Telechelic polyesters have successfully been synthesized with lipase-catalyzed polymerization. The produced telechelics had a high degree of di­functionalization, high purity (requiring little or no workup) and controlled degree of polymerization. The syntheses were performed in one-pot one-step reaction systems. LÄS MER
