  1. 1. Testing and Modelling of Electrical Traction Machines : Performance Characterisation with Measurements from Transient Operation

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Sebastian Hall; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical machines; Interior permanent magnet synchronous machines IPMSMs ; characterisation; Testing; Modelling; Electrical machines; Interior permanent magnet synchronous machines IPMSMs ; Testing; Characterisation; Modelling;

    Abstract : This thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles. The thesis divides the performance characteristics into three subcategories: The electromagnetic properties, the loss profile and the thermal behaviour of the machines. READ MORE

  2. 2. Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

    University dissertation from Department of Cell and Organism Biology, Lund University

    Author : Roberta Buffoni Hall; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; kemotaxonomi. Växters fysiologi inte kärlväxter .; Systematisk botanik; taxonomi; morfologi;

    Abstract : Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. READ MORE

  3. 3. Building patient safety in intensive care nursing Patient safety culture, team performance and simulation-based training

    University dissertation from Karlstad : Karlstads universitet

    Author : Randi Ballangrud; Marie-Louise Hall-Lord; Birgitta Hedelin; Mona Persenius; Karin Samuelsson; [2013]

    Abstract : Aim: The overall aim of the thesis was to investigate patient safety culture, team performance and the use of simulation-based team training for building patient safety in intensive care nursing.Methods: Quantitative and qualitative methods were used. READ MORE

  4. 4. Benthic fluxes of biogenic elements in the Baltic Sea Influence of oxygen and macrofauna

    University dissertation from Karlstad : Karlstads universitet

    Author : Nils Ekeroth; Sven Blomqvist; Per OJ Hall; Bjørn Sundby; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment biogeochemistry; Bioturbation; Benthic nutrient fluxes; Bottom water oxygenation; Box corer; Sediment sampling; marin ekologi; Marine Ecology;

    Abstract : This thesis investigates how benthic fluxes of phosphorus (P), nitrogen (N), and silicon (Si) change upon oxygenation of anoxic soft bottoms in the brackish, eutrophicated Baltic Sea. Direct measurements in situ by benthic landers demonstrated that fluxes of dissolved inorganic P (DIP) from anoxic bottom sediments in the Eastern Gotland Basin are higher than previously thought (Paper I).

  5. 5. On benthic fluxes of phosphorus in the Baltic Sea proper – drivers and estimates

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Nils Ekeroth; Sven Blomqvist; Per Hall; Volker Brüchert; Brita Sundelin; Jonas Gunnarsson; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marin ekologi; Marine Ecology;

    Abstract : This Thesis focuses on the exchange of phosphorus (P) across the sediment–water interface in the Baltic Sea proper, with particular attention to the influence of bioturbating macrofauna and benthic redox conditions. Benthic P fluxes have major influence on P availability in the water column, which in turn regulates growth conditions for dinitrogen fixating cyanobacteria in the Baltic proper. READ MORE
