  1. 1. Following Tweets Around : Informetric methodology for the Twittersphere

    Författare :David Gunnarsson Lorentzen; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Library and Information Science; Biblioteks- och informationsvetenskap;

    Sammanfattning : The purpose of this thesis is to critically discuss methods to collect and analyse data related to the interaction and content on the social platform Twitter. The thesis contains examples of how networked communication can be studied on Twitter, based on the affordances of the platform considering interaction with interfaces and other users. LÄS MER

  4. 3. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II

    Författare :Susanna Lindman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; peptide synthesis; turn mimetics; molecular modelling; receptor binding affinity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Sammanfattning : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. LÄS MER

  5. 4. Design and Synthesis of AT2 Receptor Selective Angiotensin II Analogues Encompassing β- and γ-Turn Mimetics

    Författare :Ulrika Rosenström; Anders Hallberg; Stephen Hanessian; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Angiotensin II; AT2; AT1; Benzodiazepine; Peptidomimetics; γ-turn; β-turn; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : Important information on the bioactive conformation of biologically active peptides may be obtained by studies of rigid peptides or well-defined secondary structure mimetics incorporated into pseudopeptides. The structural requirements for the interaction of angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe) with its AT1 and AT2 receptors were the subject of this study. LÄS MER

  7. 5. Konst och kartläggning kring 1970 : Modell, diagram och karta i konstens landskap

    Författare :Karolina Uggla; Jeff Werner; Margaretha Rossholm Lagerlöf; Annika Öhrner; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Conceptual art; maps; mapping; art and cartography; art and mapping; visual culture; art and science; scientific images; art and cybernetics; alienation; the linguistic turn; Agnes Denes; Sten Eklund; Hans Haacke; Öyvind Fahlström; Richard Long; Yoko Ono; Robert Smithson; konstvetenskap; Art History;

    Sammanfattning : The years around 1970 saw the emergence of an artistic fascination with maps and mapping. In the present thesis this fascination is conceptualised as a mapping impulse, acknowledging how the discourses of art and mapping, respectively, intertwine and merge. LÄS MER
