  1. 16. Computational Insights into Atomic Scale Wear Processes in Cemented Carbides

    Författare :Emil Edin; Rajeev Ahuja; Andreas Blomqvist; Jonas Östby; Wei Luo; Hannes Jónsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WC; Cemented Carbides; Diffusion; Wear; Interfaces; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : As Ti-alloys become more and more utilized the need for efficient and robust manufacturing of Ti-alloy components increase in importance. Ti-alloys are more difficult to machine than e.g. steel, mainly due to their poor thermal conductivity leading to rapid tool wear. LÄS MER

  3. 17. On understanding of external and internal integration in supply chains : challenges and evaluation

    Författare :Hana Hulthén; Dag Näslund; Andreas Norrman; Patrik Jonsson; Teknisk logistik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Supply chain integration; contextual factors; sales and operations planning process; S OP process; performance measures; Logistics; Logistik; Supply Chain Integration; contextual factors; Sales and Operations planning process; S OP process; Performance measures;

    Sammanfattning : Benefits of implementing Supply Chain Integration (SCI) are acknowledged in existing integration literature. Integration extending beyond functional silos and firm boundaries is expected to provide value for customers in terms of higher quality, improved service level, and reduced costs. LÄS MER

  4. 18. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

    Författare :Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. LÄS MER

  5. 19. Birth asphyxia : Fetal scalp blood sampling and risk factors for hypoxic ischemic encephalopathy

    Författare :Lena Liljeström; Maria Jonsson; Anna-Karin Wikström; Ulf Högberg; Andreas Herbst; Uppsala universitet; []
    Nyckelord :asphyxia; fetal scalp blood sampling; hypoxic ischemic encephalopathy; obstetric emergencies; operative deliveries for fetal distress; overweight; short stature; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Preventing birth asphyxia is a major challenge in delivery care. The aims of this thesis were to evaluate fetal scalp blood sampling (FBS) and explore risk factors for moderate to severe neonatal hypoxic ischemic encephalopathy (HIE). LÄS MER

  7. 20. Towards novel antibacterials : Synthesis and identification of natural product inspired inhibitors of Chlamydia trachomatis and development of chemical probes targeting virulence of Pseudomonas aeruginosa
