  1. 1. Coordinated control of Multi-Stage Inventory System

    Författare :Johan Marklund; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory systems; multi-echelon; stochastic; decentralization; centralized control; distribution system; divergent system; echelon-stock; installation-stock.;

    Sammanfattning : This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. LÄS MER

  2. 2. Supply Chain Inventory Control-Methods for Coordination and Evaluation

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply Chain; Inventory; Multi-Echelon; Stochastic; Decentralization; Centralized Control; Distribution; Divergent; Batch Ordering.;

    Sammanfattning : Thanks to the fierce competition and the globalization of markets as well as compa¬nies, supply chain management has emerged as one of the most urgent manage¬rial issues in business today. This thesis is devoted to one aspect of this vast problem area - the coordinated management/control of supply chain inventories. LÄS MER

  3. 3. Orientational dynamics of single molecules applied to protein-DNA target search

    Författare :Emil Marklund; Johan Elf; Erwin Peterman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single molecule imaging; fluorescence correlation spectroscopy; gene regulation; transcription factor; lac operon;

    Sammanfattning : Cells in all life forms regulate their genes with the help of transcription factors (TFs). These proteins turn genes on or off by binding regulatory motifs present in the DNA. Before this binding can occur, a TF needs to search and find the specific binding site in the genome of the cell. LÄS MER

  4. 4. Structural investigation of SOD1 aggregates in ALS : identification of prion strains using anti-peptide antibodies

    Författare :Johan Bergh; Thomas Brännström; Stefan L. Marklund; Peter M. Andersen; Joakim Bergström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; prion; motor neuron disease; neurodegeneration; strain; seeding; protein aggregation; transgenic mice; peptide antibodies; Neurology; neurologi;

    Sammanfattning : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. LÄS MER

  5. 5. The long and winding road : A life course approach to retirement behaviour

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Retirement Ageing Life course Well-being Work; sociologi; Sociology;

    Sammanfattning : Background: This thesis explores the retirement behaviour of older people approaching retirement decisions. The research questions in focus deal with the attitudes toward work, the retirement preferences and the subjective well-being of the "youngest old", i.e. people aged 55–64. LÄS MER
