  1. 1. Biomarkers of acute kidney injury

    Författare :Johan Mårtensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Acute kidney injury (AKI) is a common and potentially fatal complication in critically ill patients. The diagnosis relies on functional markers of decreased glomerular filtration rate (GFR) such as creatinine. Unfortunately, a rise in plasma creatinine lags behind the early structural changes that occur in response to various renal insults. LÄS MER

  2. 2. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

    Författare :Johan Mårtensson; Partikelfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

    Sammanfattning : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. LÄS MER

  3. 3. Regimented language training. Changes to brain and behaviour following intensive non-native language learning

    Författare :Johan Mårtensson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cortical thickness; Hippocampus; Plasticity; Language acquisition; Associative memory; Transfer; Education;

    Sammanfattning : The influence of foreign-language acquisition on adult brain structure remains mostly unexplored. Whilst several cross-sectional studies have led to further understanding of how language can affect brain structure, only a few longitudinal studies have been conducted. LÄS MER

  4. 4. Adapting to increased automation in the aviation industry through performance measurement and training : Barriers and potential

    Författare :Johan Rignér; Lena Mårtensson; Pernilla Ulfvengren; Don Harris; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial work science; Industriell arbetsvetenskap;

    Sammanfattning : The increased use of automation has affected the work on the flight deck. The Single European Sky ATM Research (SESAR), deployed with the purpose to increase the European ATM system performance, identifies automation as a key enabler to increase future system performance. The aviation system is a complex large socio-technical system. LÄS MER

  5. 5. On motion planning and control for truck and trailer systems

    Författare :Oskar Ljungqvist; Daniel Axehill; Johan Löfberg; Jonas Mårtensson; Linköpings universitet; []
