  1. 26. Capacity Constraints in Multi-Stage Production-Inventory Systems : Applying Material Requirments Planning Theory

    Författare :Thi Thu Thuy Huynh; Robert Grubbström; Ludvik Bogataj; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Requirements Planning; Laplace transform; Net Present Value; multi-stage multi-level production-inventory planning; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : In this thesis, capacity-constrained aspects of multi-level, multi-stage productionplanning are investigated. The aim has been to extend Material Requirements Planning Theory (MRP Theory) to cover more general problems dealing with capacity constraints, in particular when non-zero lead times are present and the processes take place in continuous time.

  3. 27. Heterocystous cyanobacteria, Dps proteins and H2 production

    Författare :Christoph Howe; Karin Stensjö; Felix Howe; Nir Keren; Uppsala universitet; []
    Nyckelord :H2 production; Cyanobacteria; Dps; ferritin-like proteins; iron; nutrient limitation; oxidative stress; biofilm; photobioreactor; iron homeostasis; H2O2;

    Sammanfattning : To mitigate climate change, CO2-emitting technologies have to be exchanged by renewable alternatives such as H2. H2 can be produced by cyanobacteria, but major efforts to enhance H2 production yields by genetic modifications or optimised cultivation conditions resulted in energetic photo-to-H2 conversion efficiencies of 4.

  4. 28. Engineering membrane proteins for production and topology

    Författare :Stephen Toddo; Daniel Daley; Roslyn Bill; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; Over-expression; Protein production; Codon optimization; Escherichia coli; AraH; NarK; mRNA secondary structure; coding sequence; ribosome binding site; RBS; topology; split-GFP; Biochemistry; biokemi;

    Sammanfattning : The genomes of diverse organisms are predicted to contain 20 – 30% membrane protein encoding genes and more than half of all therapeutics target membrane proteins. However, only 2% of crystal structures deposited in the protein data bank represent integral membrane proteins. LÄS MER

  5. 29. Reconciling Form and Function through Generative Design

    Författare :Axel Nordin; Innovation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generative design; morphological repertoire; constraint handling; optimization; customization; industrial design; engineering design;

    Sammanfattning : The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Industrial designers frequently rely on artistic experimentation, aesthetic inspiration, or design briefs. LÄS MER

  7. 30. Bakom webben : En studie av produktionsvillkor och svenska universitetswebbplatsers form och innehåll

    Författare :Christer Clerwall; Robert Burnett; Christian Christensen; Inger Lindstedt; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; web production; production of culture; Swedish university web sites; webbproduktion; kulturproduktion; svenska universitetswebbplatser; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Sammanfattning : Since their breakthrough in the mid 1990's, web sites have become one of the most important channels for communication at Swedish universities. Drawing upon the analytical framework of "the production of culture perspective", the thesis investigates how the form and content of Swedish university web sites are influenced by the production milieu in which they are produced.
