Fixed-term work in Nordic labour law

This article describes the regulation of fixed-term work and its most recent developments in Denmark, Finland, Norway and Sweden. Regulations are analyzed against the background of the Fixed-term Work Directive 1999/70/EC.

Stability analysis of transportation networks with multiscale driver decisions

Stability of Wardrop equilibria is analyzed for dynamical transportation networks in which the drivers' route choices are influenced by information at multiple temporal and spatial scales. The considered model involves a continuum of indistinguishable drivers commuting between a common origin/destination pair in an acyclic transportation network. The drivers' route choices are affected by their, r

Use of neural progenitor cell lines and astrocytes for transplantation and gene transfer to the CNS.

Popular Abstract in Swedish Transplantation av nervvävnad till hjärnan är inte en ny idé. Redan 1890, publiserade Thompson de första försöken att transplantera vuxen hjärnvävnad till det vuxna centrala nervsystemet och han rapporterade att vävnaden överlevde i sju veckor "without wholly losing its identity". Trots detta var det först under 1970-talet som metoderna för intracerebral nervcellstranspIntracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. We have investigated the feasibli

Water saturation modeling in polymer electrolyte membrane (PEM) fuel cells using a validated approach

In this work, a 3D model of a PEM fuel cell has been developed for water saturation and its effects using a validated approach considering the internal movement of water across the membrane. For different operating levels, it was found that at lower current densities, the maximum saturation occurs faraway region from the air inlet because of the decrease in ability of air to evaporate the liquid w
