  1. 16. Analysis of manufacturing supply chains using system dynamics and multi-objective optimization

    Författare :Tehseen Aslam; Amos H. C. Ng; Daniel Tesfamariam Semere; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supply Chain Management; System Dynamics; Multi-Objective Optimization; Technology; Teknik;

    Sammanfattning : Supply chains are in general complex networks composed of autonomous entities whereby multiple performance measures in different levels, which in most cases are in conflict with each other, have to be taken into account. Hence, due to the multiple performance measures, supply chain decision making is much more complex than treating it as a single objective optimization problem. LÄS MER

  3. 17. Skyddsombud i allas intresse : en rättsvetenskaplig studie

    Sammanfattning : This study is about Swedish “safety delegates” (skyddsombud). The main function of a safety delegate (SD) is to represent employees in matters of work environment (health and safety including psychosocial aspects). The legislation concerning SDs is mainly found in the Swedish Work Environment Act (WEA) and in collective agreements. LÄS MER

  4. 18. The expression of the structural proteins dendrin and Neph1 in the glomerular filtration barrier in proteinuria

    Författare :Jenny Hulkko; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: In the normal kidney, the glomerular filtration barrier successfully clears about one litre blood per minute. Damage to the filtration barrier might lead to protein leakage in the urine – proteinuria. The major ultra-structural finding in glomerular diseases with proteinuria is foot process effacement (FPE).

  5. 19. Genetic factors and the role of the NMDA receptor in pain modulation and the effect of opioids

    Författare :Aida Plesan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :pain; NMDA-receptor antagonists; genetic difference; rat strain; opioids; methadone; morphine tolerance; neuropathic pain;

    Sammanfattning : Pain perception and the response to opioid analgesics are determined by a number of factors, among which genetic variability and the activation of the NMDA-receptor for glutamate play an important role. The effects of two clinically available NMDA-receptor antagonists, ketamine (KET) and dextromethorphan (DEX), were evaluated on an animal model of acute nociception, the hot plate test, and on human experimental acute ischemic pain.

  7. 20. Seismics, 2D and 3D Inversion of Magnetotellurics : Jigsaw pieces in understanding the Skellefte Ore District

    Författare :María de los Ángeles García Juanatey; Ari Tryggavson; Ute Weckmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetotellurics; 2D inversion; 3D inversion; hard rock seismics; mineral exploration; integrated geophysics; 4D modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The Skellefte District (SD) is one of the richest metallogenic mining areas in Sweden. The main deposits consist of volcanic-hosted massive sulphides (VHMS) rich in zinc, copper, lead, gold and silver, that have been explored and mined for more than a century. LÄS MER
