1. 21. The phenomenon of the grotesque in modern southern fiction : some aspects of its form and function

   Författare :Maria Haar; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Caldwell; Capote; Faulkner; Goyen; McCullers; O Connor; Welty; macabre-grotesque; repulsive frightening-grotesque; comic-grotesque; Philip Thomson; Det groteska i litteraturen;

   Sammanfattning : After a general historical outline of the term and concept 'grotesque' attention is focused on the grotesque in Southern fiction and an attempt is made to explain the abundance of this mode in the literature of the South. It can seemingly be linked to the distinctiveness of that region as compared to the rest of the United States—a distinctiveness that has been brought about by historical, geographical, sociological and economic factors.

3. 22. Pedestal structure and stability in JET-ILW and comparison with JET-C

   Författare :Estera Stefanikova; Lorenzo Frassinetti; Per Brunsell; Joelle Mailloux; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; JET; Thomson scattering; pedestal; pedestal position; pedestal stability; Europed modelling; Physics; Fysik;

   Sammanfattning : Controlled thermonuclear fusion offers a promising concept for safe and sustainable production of electrical energy. However, there are still many issues to be investigated on the way to a commercial fusion reactor. An important point for detailed studies is connected to wall materials surrounding hot thermonuclear plasma. LÄS MER

4. 23. Ancillary actor relations : The case of EU’s leading defence primes

   Författare :Pierre Erik Gunnarsson; Peter Thilenius; Hadjikhani Amjad; Martin Lundmark; Fredrik Tell; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ancillary; actor relation; aerospace industry; Aérospatiale; Airbus; BAE; business relations; Dassault; defence acquisition; defence company; defence industry; defence procurement; EADC; EADS; EDA; EDF; EU defence; EU institutions; EU integration; Europeanization; Finmeccanica; IEPG; industrial marketing; Leonardo; SAAB; solutions marketing; strategic industries; project marketing; Thales; Thomson-CSF; OCCAR; Industriell Marknadsföring; försvarsindustri; Försvar; Försvarsindustri;

   Sammanfattning : This longitudinal research project in industrial marketing seeks to understand ancillary actors, specifically what they are, their characteristics, relations and impact on focal relations based on the empirical case of the cross-border relations of EU’s largest defence equipment producing firms (called “primes”). Ancillary actors are approached on four arenas: i) the political setting for EU defence equipment production, ii) the “primes” business relations, e. LÄS MER

5. 24. Enhanced Active Resonant DC Circuit Breakers for HVDC Grids

   Författare :Tim Augustin; Hans-Peter Nee; Marley Becerra; Jürgen Biela; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active damping; Actuator; DC circuit breakers; DC grid; DC power systems; Fast mechanical switch; Fault handling strategy; Gas discharge devices; HVDC; HVDC circuit breakers; Multilevel converters; Multiterminal HVDC; Power transmission; Spark gaps; Thomson-coil actuator; Vacuum interrupter; Voltage Source Converter VSC ; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : High-voltage DC (HVDC) grids are considered promising for the electricity grid expansion required to integrate renewable energy sources into the existing infrastructure. DC fault currents increase rapidly and lack a current zero crossing. LÄS MER

7. 25. Target and Laser Pulse Optimization for Laser-Driven Ion Acceleration

   Författare :Alexander Permogorov; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Terawatt laser; Target normal sheath acceleration; laser-driven ion acceleration; proton acceleration; double plasma mirror; Thomson parabola spectrometer; Fysicumarkivet A:2021:Permogorov;

   Sammanfattning : The research presented in this thesis is primarily focused on experimental investigations of laser-driven ion acceleration from solid targets via the target normal sheath acceleration mechanism. In particular, ways of optimizing the absorption of the laser pulse energy by free plasma electrons in the target, or modifying the shape of the accelerating electron sheath were addressed. LÄS MER
