  1. 1. Reverse Transcriptase Activity Assays for Retrovirus Quantitation and Characterization

    Författare :Anders Malmsten; Ulf Gyllensten; Clas Källander; Lynn Morris; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; retrovirus; reverse transcriptase; enzyme activity assay; MuLV; HIV; RT purification; viral load; drug susceptibility; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : Reverse transcriptase (RT) is a crucial enzyme for retrovirus replication, and its presence in the virion is indispensable for infectivity. This thesis illustrates the use of RT activity assays as tools for quantitation and characterization of different retroviruses, particularly HIV. LÄS MER

  3. 2. Kritisk granskning : mönster för kritisk undersökning i historisk och kunskapsteoretisk belysning

    Författare :Jan Willner; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES;

    Sammanfattning : The study contains a description of traditional patterns of critical reading and an analysis of their epistemological significance. The objective is to clarify an important educational concept in such a way that it can be seen how competence in critical reading can be taught and observed. LÄS MER

  4. 3. Environment-Sensitive Multifunctional Drug Delivery Systems

    Författare :Jian Qin; Mamoun Muhammed; Marcus Textor; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Materialkemi;

    Sammanfattning : Drug delivery systems (DDS) with multiple functionalities such as environment-sensitive drug release mechanisms and visualization agents have motivated the biomedical community as well as materials chemists for more than a decade. This dissertation is concerned with the development of nanoparticles for multifunctional DDS  to tackle several crucial challenges in these complex systems, including polymeric nanospheres which respond to temperature change, superparamagnetic iron oxide nanoparticles/polymeric composite for magnetic resonance imaging contrast agents and drug carriers, immunoresponse of nanomaterials and injectable magnetic field sensitive ferrogels.

  5. 4. Recycling Translations : Extraction of Lexical Data from Parallel Corpora and their Application in Natural Language Processing

    Författare :Jörg Tiedemann; Anna Sågvall Hein; Joakim Nivre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational linguistics; word alignment; parallel corpora; translation corpora; computational lexicography; machine translation; Datorlingvistik; Computational linguistics; Datorlingvistik;

    Sammanfattning : The focus of this thesis is on re-using translations in natural language processing. It involves the collection of documents and their translations in an appropriate format, the automatic extraction of translation data, and the application of the extracted data to different tasks in natural language processing.

  7. 5. Synthesis and chemical modification of some carbohydrates containing amino groups

    Författare :Jan Arnarp; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The alkylation with alkyl trifluoromethanesulfonates of hydroxyl groups in carbohydrates, containing base- or acid-labile substituents, has been examined. The reagent simultaneously transforms acetamindo groups to N-methylamino groups. Synthesis and nitrous acid deamination of methyl 4-amino-4-deoxy-β-L-arabinopyranoside has been performed. LÄS MER
