  1. 1. Cattle for beads : The archaeology of historical contact and trade on the Namib Coast

    Författare :Jill Kinahan; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Historical archaeology; contact; indigenous response; glass trade beads; commercial ceramics; nineteenth century; Namib coast; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Sammanfattning : Early contacts between indigenous pastoralists at Walvis Bay on the Namib Coast and Western seafarers are poorly documented and little understood. Trade augmented regional exchange networks with a range, of archaeologically visible and easily identifiable objects. LÄS MER

  3. 2. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

    Författare :Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; Uppsala universitet; []
    Nyckelord :Engineering physics; sensor; micro; dielectrophoresis; impedance; electrode; beads; cell; flow; bacteria; microfabrication; biosensor; electrocapture; microfluidic; planar; Lab on chip; µTAS; micro total analysis system; QCM; dispersion; field-flow fractionation; ITO; design; fabrication; Teknisk fysik;

    Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER

  4. 3. Use of Cellulose for the Preparation of Capsules and Beads with Molecularly Tailored Properties

    Författare :Katarzyna Mystek; Lars Wågberg; Bernard Cathala; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regenerated cellulose; partially modified cellulose; capsules; beads; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The continuously increasing global production of petroleum-based polymers to meet the ever growing demand for plastics for use in a multitude of industrial sectors (e.g. packaging and textiles) has an impact on human health, climate change and the entire ecosystem. LÄS MER

  5. 4. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

    Författare :Mina Larsson; Jan Lindgren; Jean-Claude Lassègues; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; Chemistry; Kemi;

    Sammanfattning : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. LÄS MER

  7. 5. Microfluidic bead-based methods for DNA analysis

    Författare :Aman Russom; Ulf Gyllensten; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; single nucleotide polymorphism; DNA analysis; SNP; microfluidics; pyrosequencing; beads; lab on a chip; hybridization; DASH; microsystem; micro totat analysis system; allele-specific extension; DASH; microcontact printing; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : With the completion of the human genome sequencing project, attention is currently shifting toward understanding how genetic variation, such as single nucleotide polymorphism (SNP), leads to disease. To identify, understand, and control biological mechanisms of living organisms, the enormous amounts of accumulated sequence information must be coupled to faster, cheaper, and more powerful technologies for DNA, RNA, and protein analysis.
