  1. 6. Viruses as a Model System for Studies of Eukaryotic mRNA Processing

    Författare :Anette Lindberg; Jan-Peter Kreivi; Göran Akusjärvi; Lars Wieslander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; ICP27; herpes simplex virus; mRNA; splicing; adenovirus; ASF SF2; Molekylärbiologi; Molecular biology; Molekylärbiologi; Medical Virology; medicinsk virologi;

    Sammanfattning : Viruses depend on their hosts for the production and spread of new virus particles. For efficient virus replication, the viral genes have adapted the strategy of being recognized and processed by the cellular biosynthetic machineries. Viruses therefore provide an important tool to study the cellular machinery regulating gene expression. LÄS MER

  3. 7. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches

    Författare :Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Henry Rice; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Vehicle suspension; Disc brake; Wheel rim Roughness noise; Interior tyre-road noise Component mode synthesis; Undeformed coupling interface;

    Sammanfattning : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. LÄS MER

  4. 8. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    Författare :Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Sammanfattning : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. LÄS MER

  5. 9. Exploring Brain Gene Expression i Animal Models of Behaviour

    Författare :Julia Lindberg; Elena Jazin; Peter Saetre; Jonathan Flint; Uppsala universitet; []
    Nyckelord :Biology; behavioural genetics; gene expression; brain; microarray analysis; domestication; animal model; haem; Canis familiaris; Vulpes vulpes; Mus musculus; Biologi;

    Sammanfattning : The genetic basis for behavioural traits is largely unknown. The overall aim of this thesis was to find genes with importance for behavioural traits related to fear and anxiety. Microarray analysis was used to screen expression profiles of brain regions important for emotional behaviour in dogs, wolves, foxes and mice. LÄS MER

  7. 10. Localic Categories of Models and Categorical Aspects of Intuitionistic Ramified Type Theory

    Författare :Johan Lindberg; Erik Palmgren; Peter LeFanu Lumsdaine; Henrik Forssell; Benno van den Berg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topos theory; predicative topos theory; ramified type theory; type theory; localic groupoids; Mathematics; matematik;

    Sammanfattning : This thesis contains three papers, all in the general area of categorical logic, together with an introductory part with some minor results and proofs of known results which does not appear to be (easily) available in the literature.In Papers I and II we investigate the formal system Intuitionistic Ramified Type Theory (IRTT), introduced by Erik Palmgren, as an approach to predicative topos theory.
