  1. 6. Formalising process calculi

    Författare :Jesper Bengtson; Joachim Parrow; Daniel Hirschkoff; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process calculi; interactive theorem proving; nominal logic; pi-calculus; CCS; psi-calculi; Computer science; Datalogi; Datavetenskap; Computer Science;

    Sammanfattning : As the complexity of programs increase, so does the complexity of the models required to reason about them. Process calculi were introduced in the early 1980s and have since then been used to model communication protocols of varying size and scope. LÄS MER

  2. 7. Prospects of Observing the Decay B_c -> J/psi + pi and the Alignment Performance in the ATLAS Experiment

    Författare :Weina Ji; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Weak modes; Inner Detector alignment; B_c ground state; ATLAS; LHC; Resonances; Fysicumarkivet A:2010:Ji;

    Sammanfattning : This thesis contains two main aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. First, a Monte Carlo based analysis of the event yield and the mass shape for the ground state of the B_c meson in the hadronic decay channel B_c -> J/psi + pi was studied. LÄS MER

  3. 8. A new generalization of the Lelong number

    Författare :Aron Lagerberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We will introduce a quantity which measures the singularity of a plurisubharmonic function $\varphi$ relative to another plurisubharmonic function $\psi$, at a point $a$. We denote this quantity by $ \nu_{a,\psi}(\varphi)$. LÄS MER

  4. 9. On the lateral organisation of the thylakoid membrane

    Författare :Ravi Danielsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thylakoid membrane heterogeneity; Plant biochemistry; Växtbiokemi; Thylakoid structure; Phase partition; Thylakoid fractions;

    Sammanfattning : In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system. LÄS MER

  5. 10. The roles of Lhcb1 och Lhcb2 in regulation of photosynthetic light harvesting

    Författare :Malgorzata Pietrzykowska; Stefan Jansson; Jean-David Rochaix; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; Lhcb1; Lhcb2; LHCII; state transitions; phosphorylation; biology; biologi;

    Sammanfattning : Photosynthesis in higher plants relies upon collection of light by chlorophyll molecules associated with light harvesting chlorophyll a/b-binding (LHC) proteins. The two most abundant of these are Lhcb1 and Lhcb2, which make up light harvesting complex (LHC) II trimers. LÄS MER
