  1. 1. Development of separation methods for DNA sequencing and oligonucleotide analysis by capillary lectrophoresis

    Författare :Peter Lindberg; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis describes the development of methods for theseparation of DNA sequencing fragments and otheroligonucleotides by capillary gel electrophoresis (CGE), and isbased on live publications.In the first work [Il, an eightfold increase in lifetime ofultra-narrow bore (2-lo-micron ID) gel filled columns comparedto 50-micron ID columns at high electrical field strengths wasexperienced, presumably due to the better heat dissipationobtained in the former columns.

  4. 3. Wideband Active and Passive Antenna Solutions for Handheld Terminals

    Författare :Peter Lindberg; Anders Rydberg; Anders Pers; Nicholas Buris; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; active antennas; impedance matching; dipole antennas; baluns; slot antennas; microstrip antennas; mobile antennas; multifrequency antennas; antenna proximity factors; receiving antennas; ferrite devices; Teknisk fysik;

    Sammanfattning : This thesis presents solutions and studies related to the design of wideband antennas for wireless handheld terminal applications. A method of electrically shortening the terminal chassis length to obtain resonance at high frequencies has been proposed and evaluated, thereby increasing the antennas impedance bandwidth. LÄS MER

  5. 4. Att synliggöra det förväntade : förskolans dokumentation i en performativ kultur

    Författare :Rebecka Lindberg; Peter Karlsudd; Håkan Löfgren; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogics and Educational Sciences; Pedagogik och Utbildningsvetenskap;

    Sammanfattning : The aim of the study is to use the documentation produced and made public in preschool to contribute with knowledge about values in preschool performative documentation practice. The study focuses on seemingly valuable actions in the documentations studied. LÄS MER

  7. 5. Electron-Impact Liquid-Jet Water-Window X-ray Sources

    Författare :Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. LÄS MER
