  2. 1. Mass Spectrometry of Biologically Active Small Molecules : Focusing on polyphenols, alkaloids and amino acids

    Author : Zdeněk Spáčil; Leopold L. Ilag; Frantisek Turecek; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LC-MS; LDI; Mass spectrometry; HPLC; UHPLC; polyphenols; phenolic acids; BMAA; Separation methods; Separationsmetoder; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : The foci of this dissertation are on advanced liquid chromatography (LC) separation and mass spectrometry (MS) techniques for the analysis of small bioactive molecules. In addition to discussing general aspects of such techniques the results from analyses of polyphenols (PPs), alkaloids and amino acids published in five appended studies are presented and discussed.

  4. 2. Implementation of digital-serial LDI/LDD allpass filters

    Author : Krister Landernäs; Johnny Öberg; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Elektronik;

    Abstract : In this thesis, digit-serial implementation of recursive digital filters is considered. The theories presented can be applied to any recursive digital filter, and in this thesis we study the lossless discrete integrator (LDI) allpass filter. READ MORE

  5. 3. LDI-MS strategies for analysis of polymer degradation products, additives and drugs

  7. 5. Laser Doppler Flowmetry and Imaging: Methodological Studies

    Author : Siv Bornmyr; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital photography.; cold intolerance; sympathetic nervous system; flow cessation external pressure; skin temperature; thermography; skin blood flow; laser doppler imaging; Laser doppler flowmetry; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Laser Doppler flowmetry (LDF) and laser Doppler imaging (LDI) are modern methods for non-invasive and continuous assessment of skin blood flow. The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells. READ MORE
