  1. 1. Masking Moments The Transitions of Bodies and Beings in Late Iron Age Scandinavia

    Detta är en avhandling från Stockholm : Institutionen för arkeologi och antikens kultur

    Författare :Ing-Marie Back Danielsson; Stockholms universitet.; [2007]
    Nyckelord :HUMANIORA; HUMANITIES; Masking practices; masks; transitions; Iron Age; Scandinavia; kuml; body; metaphorical thinking; miniaturization; queer theory; feminism; sex; gender; personhood; rune stones; gold foil figures; oral literacy; food preparation; burials; HUMANITIES and RELIGION History and philosophy subjects Archaeology subjects Archaeology; North European; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Arkeologiämnen Arkeologi; nordeuropeisk; arkeologi; Archaeology;

    Sammanfattning : This thesis explores bodily representations in Late Iron Age Scandinavia (400–1050 AD). Non-human bodies, such as gold foil figures, and human bodies are analysed. The work starts with an examination and deconstruction of the sex/gender categories to the effect that they are considered to be of minor value for the purposes of the thesis. LÄS MER

  2. 2. Miniaturized, Membrane-Based and Environmentally Green Sample Preparation Systems: Applications for Biological and Environmental Aqueous Samples

    Detta är en avhandling från Analytical Chemistry, Lund University

    Författare :Thaer Barri; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Free concentration; Exhustive extraction; Microporous membrane liquid-liqid extraction; Miniaturization; Supported liquid membrane extraction; Environmental chemistry; Miljökemi;

    Sammanfattning : Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in supported liquid membrane (SLM) extraction or one aqueous phase and another organic phase (as in microporous membrane liquid-liquid extraction (MMLLE)).

  3. 3. Microfluidic biosensing systems based on enzymes, antibodies and cells

    Detta är en avhandling från Department of Analytical Chemistry, Lund University

    Författare :Richard Davidsson; Lund University.; Lunds universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; chemiluminescence; immobilization; cell; antibody; enzyme; miniaturization; Microfluidic; microchip;

    Sammanfattning : The rapid developments within the life science and biotechnology areas put up ever-new demands on more sophisticated techniques and methods for chemical and biological analysis to reach deeper insight into the events at molecular level. Miniaturisation of assays and systems on microchips is one way to increase throughput and advance through parallel analysis lines, multiplexing and integration. LÄS MER

  4. 4. New methods for sensitive analysis with nanoelectrospray ionization mass spectrometry

    Detta är en avhandling från Stockholm : KTH

    Författare :Patrik Ek; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry; electrospray ionization; nanoelectrospray ionization; adjustable gap; emitter; miniaturization; improved sensitivity; nanoliter picoliter sample volumes; Alzheimer’s disease; amyloid-beta Aβ ; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Sammanfattning : In this thesis, new methods that address some current limitations in nanoelectrospray mass spectrometry (nESI-MS) analysis are presented. One of the major objectives is the potential gain in sensitivity that can be obtained when employing the proposed techniques. LÄS MER

  5. 5. On chip integrated sample preparation for proteomics

    Detta är en avhandling från Department of Electrical Measurements, Lund University
