  1. 21. Congestion control in wireless cellular networks

    Författare :Sara Landström; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : Through the introduction of the third generation of mobile cellular network technologies a major step towards a ubiquitious and wireless access to the Internet has been taken. There are however still challenges due to the different characteristics and prerequisites of wired and wireless networks. An important network element is congestion control. LÄS MER

  3. 22. Performance Analysis and Improvement of PR-SCTP in an Event Logging Context

    Författare :Mohammad Rajiullah; Anna Brunstrom; Thomas Dreibholz; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Due to certain shortcomings in TCP and UDP, the Stream Control Transmission Protocol (SCTP) was defined for transporting telephony signaling traffic. The partially reliable extension of SCTP, PR-SCTP, has been considered as a candidate for prioritizing content sensitive traffic and trading reliability against timeliness for applications with soft real time requirements.

  4. 23. Functional dynamics of glycosyltransferases : Solution-state NMR studies of peripheral membrane proteins involved in glycolipid biosynthesis in bacteria

    Författare :Joan Patrick; Lena Mäler; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik;

    Sammanfattning : Antibiotic resistance is an existential threat enabled by bacterial adaptation and fuelled by inappropriate use of medication. The ensuing shortage of effective treatments has led to a rise in deaths linked to resistant bacterial pathogens. LÄS MER

  5. 24. Neonatal screening in Sweden and disease-causing variants in phenylketonuria, galactosaemia and biotinidase deficiency

    Författare :Annika Ohlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Phenylketonuria, galactosaemia and biotinidase deficiency were the first three inborn errors of metabolism to be included in the Swedish programme. This thesis describes these conditions with an emphasis on screening performance and disease-causing genetic variants in the patients. LÄS MER

  7. 25. Glycosylation of microsomal proteins and their relationship to peroxisomes

    Författare :Eeva-Liisa Appelkvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The distribution of glycoproteins in rough and smooth microsomes and Golgi membranes was studied using proteolytic treatment of intact vesicles. About half of the protein-bound sugar residues could be removed by this treatment, indicating the presence of glycoproteins on both surfaces of the membrane. LÄS MER
