  1. 16. Implications of myocardial dysfunction before and after aortic valve intervention

    Författare :Henrik Hultkvist; Farkas Vánky; Rolf Svedjeholm; Jonas Holm; Odd Bech-Hanssen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : BACKGROUNDPostoperative heart failure in the setting of aortic valve surgery results in poor long-term survival. We hypothesized that there could be a myocardial factor that is not addressed by risk scores currently available. We speculated that this myocardial factor could be diastolic dysfunction. LÄS MER

  3. 17. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conservation; Population structure; Genetics; Aquaculture; Hybridization; Corkwing wrasse; Cleaner fish; Sea lice; Symphodus melops; Escapee; Range expansion;

    Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER

  4. 18. Correlation Effects in One-dimensional Electron Systems

    Författare :Peter Sandström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exclusion statistics; resonant tunneling; one dimension; correlated electrons; charge quantization; persistent currents; Aharonov-Bohm effect; Luttinger liquid;

    Sammanfattning : Theoretical studies suggest that an interacting one-dimensional electron system does not behave as a Fermi liquid. Instead, it is predicted to form a Luttinger liquid characterized e.g. by the absence of fermionic quasiparticles and interaction-dependent power-laws for transport quantities. LÄS MER

  5. 19. Simulation of Economical Performance of Isolated Rural Mini-Grids

    Författare :Al-Mas Sendegeya; Lennart Söder; Eriabu Lugujjo; Mikael Amelin; Alex Kyaruzi; KTH; []
    Nyckelord :Price sensitivity; system operators; Monte Carlo simulation;

    Sammanfattning : Prior knowledge about the possible characteristics of demand and supply is vital in the planning and operation of economically sustainable isolated rural power systems. System modelling and simulation is one of the tools that can be used in planning and assessing the performance of these systems. LÄS MER

  7. 20. Swedish district heating systems and a harmonised European energy market : means to reduce global carbon emissions

    Författare :Jörgen Sjödin; Sven Werner; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Energy systems in Europe are becoming more harmonised and the European Union is working to establish a single market for energy. In this thesis, it is therefore regarded as a system failing to consider a separate and isolated Swedish energy system. Extending the system boundaries enables increased resource efficiency. LÄS MER
