6. Elastic Neutron Scattering at 96 MeV
Sammanfattning : A facility for studies of elastic neutron scattering in the 50–130 MeV range has been developed. In addition to elastic neutron scattering, it has been used for (n,p) and (n,d) reaction experiments. The performance of the device has been illustrated in measurements of the (n,p) and (n,n) cross sections on 1H and 12C. LÄS MER
7. Determining the effects of regulatory parameters on the structural dynamics of P-type ATPase membrane transporters
Sammanfattning : Proteins are macromolecular machines with roles in all cellular activities and structures. The functional properties of each protein is the result of its combination of 3D-structure and inherent dynamics, and a wealth of structural and dynamic mechanisms have evolved to regulate protein activity.

8. MYC and MexR interactions with DNA : a Small Angle Scattering perspective
Sammanfattning : Protein-DNA complexes govern transcription, that is, the cellular mechanism that converts the information stored in the DNA into proteins. These complexes need to be highly dynamic to respond to external factors that regulate their functions in agreement with what the cells need at that time. LÄS MER
9. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure
Sammanfattning : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. LÄS MER
10. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS
Sammanfattning : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. LÄS MER
