  1. 21. Bronopol - ett miljöproblem i Sverige?

    Magister-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Evelina Olofsson; [2008]
    Nyckelord :Bronpol; miljöproblem; GC;

    Sammanfattning : Bronopol (2-brom-2nitropropan-1,3-diol) occurs in many products, for example cosmetics, medicines and industrial water systems. In this thesis Bronopol was investigated to see if it is an environmental problem in Sweden. As a starting point two existing analysis methods was used to combine to one. LÄS MER

  3. 22. Halfsphere Derivatisation of Magnetic Micro Particles

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för biologi och kemiteknik; Akademin för hållbar samhälls- och teknikutveckling

    Författare :Nadea Dilanson; [2008]
    Nyckelord :;

    Sammanfattning : Abstract   This exam project is an effort to derivatize one side of magnetic beads with one kind of molecule  , and another one on the opposite side. First the surface of the sphere is loaded with a suitable linker with, e.g. amino or hydroxyl groups. LÄS MER

  4. 23. Metodutveckling för analys av PBDE och HBCD i sediment

    Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Börje Sundvall; Linda Johansson; [2007]
    Nyckelord :PBDE; HBCD; bromerade flammskyddsmedel; sediment; extraktionsmetod;

    Sammanfattning : Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. LÄS MER

  5. 24. Decision Support System for Fault Isolation of JAS 39 Gripen : Development and Implementation

    Magister-uppsats, Institutionen för datavetenskap

    Författare :Anders Holmberg; Per-Erik Eriksson; [2006]
    Nyckelord :Fault Detection Isolation; FDI; Hypothesis Tests; JAS 39 Gripen; Fuel System;

    Sammanfattning : This thesis is a result of the increased requirements on availability and costs of the aircraft Jas 39 Gripen. The work has been to specify demands and to find methods suitable for development of a decision support system for the fault isolation of the aircraft. The work has also been to implement the chosen method. LÄS MER

  7. 25. On Routing Two-Point Nets Across a Three-Dimensional Channel

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Patrik Hurtig; [2005]
    Nyckelord :Electronics; two-point nets; routing; microchip; Elektronik;

    Sammanfattning : Routing techniques for plain ’flat’ microchips have been developed extensively and will soon reach its limitations. One natural step would be to develop chips which are manufactured in a more cubic type of volume, as oppose to the classical flat design. LÄS MER
