  1. 16. Structure-Function Studies of Bacteriophage P2 Integrase and Cox protein

    Författare :Jesper Eriksson; Elisabeth Haggård; Karin Hammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage P2; site-specific recombination; integrase; transcriptional switch; Genetics; Genetik;

    Sammanfattning : Probably no group of organisms has been as important as bacteriophages when it comes to the understanding of fundamental biological processes like transcriptional control, DNA replication, site-specific recombination, e.t.c.The work presented in this thesis is a contribution towards the complete understanding of these organisms.

  2. 17. All-fiber modulators for laser applications

    Författare :Mikael Malmström; Fredrik Laurell; Simon Fleming; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; All-fiber; fiber optics; modulation; q-switching; mode-locking;

    Sammanfattning : The objective of this thesis was to explore the usefulness of all-fiber modulators for laser applications. The modulators were all based on refractive index change achieved in the core of the studied fiber- components, exploiting either the elasto-optic effect or the electro-optic effect. LÄS MER

  3. 18. Atomically Resolved ac-Mode Atomic Force Microscopy in Ultra-High Vacuum

    Författare :Lars Olsson; Franz Giessibl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When the atomic force microscope (AFM) was invented in 1986, it was anticipated that the technique should be able to produce atomically resolved images with aquality similar to what was routinely obtained with the scanning tunnelling microscope (STM). Even though the AFM quickly became a very popular technique, the development toward ultra-high resolution imaging turned out to be slow due to problems of both fundamental and technical nature.

  4. 19. Buyers and Sellers on the Stockholm Housing Market

    Författare :Petter Bengtsson; Patrik Aspers; Magnus Bygren; Bengt Larsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; buyers of housing; sellers of housing; market practices; homes; housing markets; Stockholm County; switch-role markets; theory of modes; Sociology; sociologi;

    Sammanfattning : Buying and selling housing is for most a very important event that can strongly affect their financial situation. At the same time homes are recognized as places with great importance above and beyond financial matters and in everyday talk and in the previous literature homes are described as safe-havens, status symbols, influencing networks of friends and acquaintances, canvasses for projecting identity, tied to gentrification, segregation and much more.

  5. 20. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    Författare :Gang Xu; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER
