  1. 16. Sucrose cleavage pathways in aspen wood

    Författare :Umut Rende; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Cellulose is the main component of wood and one of the most important renewable raw materials. In several tree species including Populus species, carbon for cellulose biosynthesis is derived from the disaccharide sucrose. LÄS MER

  3. 17. Three problems with internetworking in cellular networks

    Författare :Lars-Åke Larzon; []
    Nyckelord :;

    Sammanfattning : Over the last decade, cell phones have gone from providing the traditional interactive voice service to also include support for Internet services. Cellular networks that originally were designed for cost-efficient voice services supply low bandwidth, high error rates and long round-trip delays, which poorly fit the generous header sizes, lack of error tolerance and reliance on retransmissions of the Internet.

    Sammanfattning : Glucosamine (GlcN) and glucosamine sulfate (GS) have been used to treat the patients with osteoarthritis(OA) as a disease-modifying agent. Previousin vitro studies have focused on the effects of GlcN or GSon cartilage metabolism, whereas in vivo studies have investigated their potential for the treatment of OA. LÄS MER

  5. 19. Mobile Agent Approach to Congestion Control in Heterogeneous Networks

    Författare :Hong Van Nguyen; Oliver Popov; Love Ekenberg; David Billard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : One of the motivations to study the behavior of the Internet is to find out the best way to maintain the relative stability of the global network. This leads into the investigations of events that impair the performance of the system such as congestion that occurs whenever the demand for resources exceed the available capacity. LÄS MER

  7. 20. Glucosyltransferase toxins from clostridia : molecular interactions with cells

    Författare :Esteban Chaves Olarte; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : An enzymatic activity was recently described for the group of Large Clostridial Cytotoxins (LCTs). This activity is glucosyltransfer and consists in the covalent addition of glucose, from UDP-glucose (UDP-Glc) to threonine 35 of small GTPases of the Rho subfamily. LÄS MER
