  1. 11. Glioneuronal tumours in childhood : Clinical picture, long-term outcome and possible new treatments

    Författare :Christoffer Ehrstedt; Gunnar Ahlsten; Bo Strömberg; Ann-Margret Rydell; Anja Smits; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioneuronal tumour; ganglioglioma; dysembryoplastic neuroepithelial tumour; childhood; cognition; psychosocial; HRQoL; outcome; mTOR pathway; somatostatin receptor; Pediatrik; Pediatrics;

    Sammanfattning : Background: Glioneuronal tumours are a subgroup of low-grade tumours of the central nervous system (CNS), often causing epilepsy. Overall survival is excellent, but data regarding long-term seizure outcome and late effects are scarce. LÄS MER

  2. 12. Grid connection of offshore renewable energy sources

    Författare :Christoffer Fjellstedt; Karin Thomas; Mats Leijon; Daniel Månsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grid connection; Electronic filters; Power transformers; Offshore collection grids; HVDC transmission; HVAC transmission; Marine current energy; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : In order to achieve net zero emissions from the electricity sector, the proportion of renewable energy sources connected to the electrical grid needs to be increased significantly in the coming years. Established renewable energy sources, such as wind power and solar power, will certainly be crucial in achieving this. LÄS MER

  3. 13. A Dipole Model for High Energy QCD

    Författare :Christoffer Flensburg; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Flensburg;

    Sammanfattning : This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. LÄS MER

  4. 14. Computational Studies of Protein Synthesis on the Ribosome and Ligand Binding to Riboswitches

    Författare :Christoffer Lind; Johan Åqvist; Alexander MacKerell Jr; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binding free energy; Ribosome; Codon reading; Translation initiation; Translation termination; Mitochondrial translation; Release factor; Purine riboswitch; Molecular Dynamics; Free Energy Perturbation; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : The ribosome is a macromolecular machine that produces proteins in all kingdoms of life. The proteins, in turn, control the biochemical processes within the cell. It is thus of extreme importance that the machine that makes the proteins works with high precision. LÄS MER

  5. 15. Observing the darkest matter of the genome : expression of human endogenous retrovirus W elements

    Författare :Christoffer Nellåker; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The human genome is composed of coding genes and vast stretches of sequences largely considered junk. Researchers are, however, uncovering widespread and extensive transcription of not only the coding, but also of the non-coding sequences in the genomes of many species. LÄS MER
