1. 21. Surface Coatings as Xenon Diffusion Barriers for Improved Detection of Clandestine Nuclear Explosions

   Författare :Lisa Bläckberg; Mattias Klintenberg; Henrik Sjöstrand; Anders Ringbom; Kai Vetter; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioxenon; Gas Diffusion Barrier; Plastic Scintillator; Comprehensive Nuclear-Test-Ban Treaty; Atomic Layer Deposition; Al2O3; Molecular Dynamics; Light Transport;

   Sammanfattning : This thesis investigates surface coatings as xenon diffusion barriers on plastic scintillators. The motivation for the work is improved radioxenon detection systems, used within the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT).One type of radioxenon detection systems used in this context is the Swedish SAUNA system.

3. 22. Företagares agerande för hembygdens utveckling

   Författare :Lisa Bois; Darush Yazdanfar; Saeid Abbasian; Ulrika Sjödin; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mundane Societal Entrepreneurship; Entrepreneurial Motivation; Attributes for Local Area Development; vardagligt samhällsentreprenörskap; entreprenörens drivkraft; faktorer för lokal utveckling;

   Sammanfattning : This thesis describes the connection between mundane societalentrepreneurship and local area development in a rural sparsely populatedcontext. It is a qualitative study from a holistic view on the actors. The empiricalwork consists of three deep case studies from one of the most sparsely populatedregions in Europe. LÄS MER

4. 23. District Heating Development : Prosumers and Bottlenecks

   Författare :Lisa Brange; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Prosumers; Bottlenecks; Pressure; Differential pressure; Planning; Simulations;

   Sammanfattning : The overarching objective of the studies in this thesis is to solve issues associated with the current district heating development in order to improve the efficiency, and thus the environmental performance, of district heating systems. More specifically, the aim is to solve issues related to prosumers and bottlenecks in district heating networks. LÄS MER

5. 24. Den rationella fabriken : om funktionalismens rötter

   Författare :Lisa Brunnström; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; industrial architecture; taylorism and modernism rational architecture; the rationalization movement daylight factories; Swedish factories factory planning;

   Sammanfattning : This thesis covers the period between 1900 and 1930 and deals with the planning and design of factory buildings during the emergence of taylorism in Sweden. It presents a new perspective where modernism stands out as a consequence of the rationalization movement. LÄS MER

7. 25. Renormalization in Effective Field Theory and Hidden Radiation

   Författare :Lisa Carloni; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renormalization; Effective theories; Phenomenological Models; Hidden Sectors;

   Sammanfattning : This thesis dealswith the field of high-energy particle physics. It ismainly concernedwith two issues: the “renormalization of effective field theories” and the “detection of hidden sectors”. The first two papers are dedicated to the renormalization issue while the second two deal with the hidden sectors. LÄS MER
