  1. 6. Controlling DNA compaction and the interaction with model biomembranes

    Författare :Marie-Louise Ainalem; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; model biomembrane; DNA compaction; cryo-TEM; null ellipsometry; dynamic light scattering; toroid; bilayer; neutron reflectivity; dendrimer; PAMAM; DNA; poly amido amine ;

    Sammanfattning : The studies described in this thesis forms part of a larger collaborative project, Neonuclei, with the objective to design a module for packaging the negatively charged DNA into a ”neonucleus” with transcription competence. There are many applications that require control of DNA compaction, i.e. packaging or condensation. LÄS MER

  3. 7. Genetics and Expression of Glycosphingolipids in the P1PK and GLOB Histo-Blood Group Systems

    Författare :Julia Westman; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosphingolipid; glycosyltransferase; null allele; GLOB; P1PK; Blood group;

    Sammanfattning : The glycosphingolipid (GSL) antigens in the clinically important P1PK and GLOB blood group systems are present on erythrocytes as well as other tissues and are so-called histo-blood group antigens. Blood group antigens of carbohydrate nature are products of enzymes, so-called glycosyltransferases, adding sugars in a step-wise manner to an acceptor substrate. LÄS MER

  4. 8. The Syntax of Past Participles. A Generative Study of Nonfinite Constructions in Ancient and Modern Italian

    Sammanfattning : The purpose of this thesis is double. First, it will be shown that a number of problems of the syntax of ancient, literary Italian lend themselves readily to an analysis in terms of the Theory of Principles and Parameters. LÄS MER

  5. 9. Syntaktisk variation och förändring : en studie av subjektslösa satser i fornsvenska

    Författare :David Håkansson; Christer Platzack; Tor Anders Åfarli; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; diachronic syntax; syntactic change; language variation; Old Swedish; referential subjects; null subjects; word order; information structure; verbal agreement; quantitative analysis; Scandinavian languages; Nordiska språk; Scandinavian Languages; Nordiska språk; information structure; word order; null subjects; referential subjects; Old Swedish; language variation; diachronic syntax; syntactic change; verbal agreement; quantitative analysis;

    Sammanfattning : The topic of this thesis is subjectless clauses in Old Swedish (1225–1526). The thesis focuses on referential subjects, and addresses the problem of why the possibilities to leave out such subjects have been reduced during the history of Swedish. The dissertation consists of three main parts, divided into eight chapters. LÄS MER

  7. 10. Optional rhemes and omitted undergoers : An event structure approach to implicit objects in Swedish

    Författare :Johanna Prytz; Cecilia Falk; Ida Larsson; Marit Julien; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; implicit objects; object omission; null objects; object drop; objectless sentences; pseudo-transitive; non-core transitive; transitivity; Swedish; event structure; argument structure; the syntax-semantic interface; implicita objekt; objektsutelämning; nollobjekt; objektslösa satser; pseudotransitiva verb; transitivitet; eventstruktur; argumentstruktur; Scandinavian Languages;

    Sammanfattning : The aim of this thesis is to define the essential syntactic-semantic properties of three types of objectless sentences in present-day Swedish. The three types of objectless sentences are labeled descriptively as follows: Implicit Object Read type (IOR) with pseudo-transitive verbs like läsa ‘read’; Implicit Object Open type (IOO), which involves various sets of transitive verbs like öppna ‘open’ and bära ‘carry’; and Implicit Object Kill type (IOK), which typically involves destruction verbs like döda ‘kill’.
