  1. 1. Solid-phase glycoconjugate synthesis : on-resin analysis with gel-phase ¹9F NMR spectroscopy

    Författare :Mickael Mogemark; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Solid-phase synthesis; protective groups; linkers; monitoring; gel-phase; 19F NMR spectroscopy; carbohydrates; oligosaccharides; glycopeptides; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : An efficient and versatile non-destructive method to analyze the progress of solid-phase glycoconjugate synthesis with gel-phase 19F NMR spectroscopy is described. The method relies on use of fluorinated linkers and building blocks carrying fluorinated protective groups. LÄS MER

  3. 2. Drug Analysis : Bioanalytical Method Development and Validation

    Författare :Mikaela Malm; Yngve Bergqvist; Anders Colmsjö; Uppsala universitet; []
    Nyckelord :Analytical chemistry; African trypanosomiasis; calibration model; chiral chromatography; dried blood spots; eflornithine; evaporative light-scattering detection; HIV AIDS; lamivudine; liquid chromatography; malaria; nevirapine; piperaquine; pneumonia; solid-phase extraction; sulfadoxine; sulfamethoxazole; validation; zidovudine; Analytisk kemi;

    Sammanfattning : This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries. Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography. LÄS MER

  4. 3. The Prodromal Phase of What? : A Metapsychiatric Analysis of the Prodromal Phase of Schizophrenia

    Författare :Anna-Karin Neubeck; Lennart Nordenfelt; Lisbet Palmgren; Lars Jacobsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Schizophrenia; trauma; prodromal phase; prodromal phenomenon; qualitative method; causality; Schizofreni; trauma; prodromalfas; prodromalfenomen; kvalitativ metod; kausalitet; Psychiatry; Psykiatri;

    Sammanfattning : Prodromes of schizophrenia or prodromes of psychosis are a relatively new and expanding field of interest in psychiatric research. They are seen by some researchers as the initial symptom of having schizophrenia and have become a crucial topic in early psychosis research and intervention. LÄS MER

  5. 4. Regularity properties of two-phase free boundary problems

    Författare :Erik Lindgren; Henrik Shah gholian; Regis Monneau; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Mathematical analysis; Analys;

    Sammanfattning : This thesis consists of four papers which are all related to the regularity properties of free boundary problems. The problems considered have in common that they have some sort of two-phase behaviour.In papers I-III we study the interior regularity of different two-phase free boundary problems. LÄS MER

  7. 5. Computer methods for voice analysis

    Författare :Svante Granqvist; KTH; []
    Nyckelord :voice analysis; perceptual analysis; fundamental frequency; correlogram; aperiodicity; Fourier analysis; high-speed imaging; laryngoscopy; vocal fold vibration; voice accumulation.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis consists of five articles and a summary. Thethesis deals with methods for measuring properties of thevoice. The methods are all computer-based, but utilisedifferent approaches for measuring different aspects of thevoice. Paper I introduces the Visual Sort and Rate (VSR) method forperceptual rating of voice quality. LÄS MER
