  1. 1. Method and technique development in peptide and protein mass Spectrometry

    Författare :Kristina Håkansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; electrospray ionization; peptide sequencing; Fourier transform ion cyclotron resonance; hydrogen deuterium exchange; protein structure; Materialvetenskap; Materials science; Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Mechanistic studies and applicability of several methods and techniques for studying peptides and proteins with mass spectrometry are presented. A model for the protein molecular ion formation in explosive matrix-assisted plasma desorption mass spectrometry is proposed, involving a contribution from the chemical energy release during conversion of the explosive, an enhanced protonation through collisions with products from the explosive decay, and electron scavenging by other products.

  3. 2. Reactors and biosensors for improved microbial degradation of acetonitrile

    Författare :Kristina Håkansson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; denitrification; nitrification; on-line analysis and control; Clark electrode; biosensor; biofilm process; acetonitrile; microbial degradation;

    Sammanfattning : Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concentrations.

  7. 5. Beyond Recreational Gambling : a Psychological Perspective on Risk- and Problem Gambling

    Författare :Kristina Sundqvist; Peter Wennberg; Jan Blomqvist; Markus Jansson Fröjmark; Anders Håkansson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; risk gambling; problem gambling; gambling motives; personality; Psychology; psykologi;

    Sammanfattning : The general aim of this thesis was to examine risk gambling in the general population from a psychological perspective. This was done in three studies targeting personality, risky alcohol habits and gambling motives, respectively. LÄS MER
