  1. 1. Purification Processes for Complex Biomacromolecules

    Författare :Hans Blom; Helena Grennberg; Mats Lundgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; enzymes; mucins; fractionation; plasmid DNA; analysis; clarification; process design; Chemistry with specialization in Surface Biotechnology; Kemi med inriktning mot ytbioteknik;

    Sammanfattning : This thesis details various techniques and considerations for the purification of complex biomacromolecules. Initially an α-mannosidase from babaco fruit was purified using anion exchange-, lectin affinity- and size exclusion chromatography. LÄS MER

  3. 2. Det komplexa deltagandet : Praktikgemenskaper, kunskapsprocesser och arbetsmiljöarbete vid ett pappersbruk

    Författare :John Sjöström; Boel Berner; Johan M. Sanne; Kaj Frick; Jan Ch. Karlsson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; work environment; occupational health and safety management; worker participation; communities of practice; workers’ collective; Arbetsmiljö; arbetsmiljöarbete; deltagande; praktikgemenskaper; arbetarkollektiv;

    Sammanfattning : Arbetsmiljölagen ger anställda och deras representanter, skyddsombuden, rätt att delta i det systematiska arbetsmiljöarbete som arbetsgivaren har skyldighet att arrangera. Forskning om deltagande har i stor utsträckning varit fokuserad påstrukturella och organisatoriska förutsättningar för anställdas deltagande. LÄS MER

  4. 3. Computer-aided optimization of complex processes in production systems and urban environments

    Författare :Mikael Yamanee-Nolin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; modeling; simulation; complex processes; process systems engineering; preparative chromatography; blue-green systems;

    Sammanfattning : Complex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. LÄS MER

  5. 4. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes

    Författare :Nathalie Pérez Rodríguez; Magnus Land; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cu and Fe isotopes; fractionation; tailings; plants; phytoremediation; organic amendments; soil bacteria; Cu and Fe cycle; covellite; redox processes; Applied Geology; Tillämpad geologi;

    Sammanfattning : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. LÄS MER

  7. 5. Structures in complex systems : Playing dice with networks and books

    Författare :Sebastian Bernhardsson; Petter Minnhagen; Stefan Bornholdt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex systems; networks; statistical physics; biological networks; quantitative linguistics; word frequencies.; Physics; Fysik;

    Sammanfattning : Complex systems are neither perfectly regular nor completely random. They consist of a multitude of players who, in many cases, playtogether in a way that makes their combined strength greater than the sum of their individual achievements. LÄS MER
