1. 1. Electron Heating and Acceleration at Earth’s Collisionless Bow Shock

   Författare :Martin Lindberg; Andris Vaivads; Philippe Savoini; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron; heating; Acceleration; MMS; Shock; space; plasma; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Cosmic rays are ultra-relativistic particles traveling near the speed of light permeating the galaxy. Collisionless shock waves with their ubiquity throughout the universe and excellent capability of accelerating charged particles offer an explanation to the origin of cosmic rays. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmic rays; event generators; colour factors; High energy interactions; hadronic jets; QCD; the Linked Dipole Chain model; quantum mechanics; relativity; gravitation; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; Kosmisk strålning; högenergi; classical mechanics; Mathematical and general theoretical physics; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Kharraziha;

   Sammanfattning : In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented.

4. 3. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

   Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

   Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER

5. 4. Colour Reconnection and Weak Showers

   Författare :Jesper Roy Christiansen; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Merging; Weak interactions; Parton Showers; Event generators; hadron collisions; Colour Reconnection; Fragmentation; Fysicumarkivet A:2015:Christiansen;

   Sammanfattning : This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. LÄS MER

7. 5. Characterization of folding dynamics and accelerated electron transfer in proteins

   Författare :Anna Katrine Museth; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : The research presented in this thesis is divided in two: The first part is a study of the intracellular protein human copper zinc superoxide dismutase which has been associated with the fatale disease Amyotrophic lateral Selerosis (ALS). ALS is a progressive neurodegenerative disease of motor neurons, and in the cases where the disease is inheriled (fALS), roughly 15% is caused by mutations in human copper·zinc superoxide dismutase (CuZnSOD).
