  1. 11. Extending the capabilities of polarizable embedding through damped linear response theory

    Författare :Morten Steen Nørby; Jacob Kongsted; Hans Jörgen Aagaard Jensen; Patrick Norman; Stephan Sauer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : One of the greater challenges of modern quantum chemistry is to meet the growing demands of a detailed description of macro molecules, such as proteins and RNA/DNA. The size of such systems make it an almost impossible task to, from first principle calculations, obtain any detailed information regarding electronic structure. LÄS MER

  3. 12. Equality of Access in Health Care

    Författare :Katarina Steen Carlsson; Hälsoekonomi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; financial and time cost; socio-economic variation; hopsital care; concentration index; consumption possibilities; definition; opportunity; equality of access; equity; Social economics; Social ekonomi;

    Sammanfattning : Equality of access may be defined and operationalised in several ways. Paper I, 'Equality of access. Definitions and policy implications', proposes a theoretical outline of possible definitions of equal access, of the policy measures needed to attain equality and of their consequences. LÄS MER

  4. 13. Impact on the Distribution System due to Plug-In Electric Vehicles and Changes in Electricity Usage

    Författare :David Steen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in hybrid electric vehicle PHEV ; Electric vehicle EV ; Plug-in Electric Vehicle PEV ; Open loop radial distribution system; Electrical distribution system; Load management;

    Sammanfattning : Replacing conventional vehicles by Plug-in Electric Vehicles (PEVs) would likely increase electricity demand and put higher stress on the electrical power system. This thesis presents an approach to evaluate the impact on electrical distribution systems (DSs) caused by charging PEVs and load management of heating loads. LÄS MER

  5. 14. Modelling of Demand Response in Distribution Systems

    Författare :David Steen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Large scale integration of plug-in electric vehicles (PEVs) and intermittent renewable energy sources, such as solar PV and wind power, could affect the way in which the power system is planned, operated and controlled. In such systems, it could be desirable to utilize the flexibility of the demand, i.e. LÄS MER

  7. 15. Novel Interactors of X-linked Inhibitor of Apoptosis Protein : Expression and Effects on Tumor Cell Death

    Författare :Håkan Steen; Dan Lindholm; Bertrand Joseph; Uppsala universitet; []
    Nyckelord :Neurobiology; XIAP; tumor cell death; apoptosis; caspases; basic helix-loop-helix protein; Neurobiologi;

    Sammanfattning : Programmed cell death, or apoptosis, has during the last decade received a lot of attention due to its involvement in a large number of pathological conditions. Since death is always irreversible, it is important for cells to fully control the initiation and execution of this process. LÄS MER
