    Sammanfattning : Is childcare a safety net for vulnerable children? This paper investigates the role of childcare for the health outcomes of children whose parents are unemployed. Exploiting time variation in childcare access resulting from a reform requiring Swedish municipalities to provide childcare also for children with unemployed parents, we estimate causal effects on health, as measured by register data on hospitalizations.

  4. 18. Prokaryotic Arsenic Resistance - Studies in Bacillus subtilis

    Författare :Emil Aaltonen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ArsB; Bacillus subtilis; arsenic resistance; arsenate reduction; arsenite transport; gene regulation; arsenate; ArsR; arsenite; transmembrane topology; Acr3; ArsK;

    Sammanfattning : Arsenic is a toxic metalloid which is found all over the globe. Due to its toxicity and wide abundance, all living organisms have evolved intrinsic arsenic resistance systems. In this study, three proteins that provide arsenic resistance in the Gram-positive bacterium Bacillus subtilis have been investigated. LÄS MER

  5. 19. Ground Monitoring using Resistivity Measurements in Glaciated Terrains

    Författare :Jaana Aaltonen; KTH; []
    Nyckelord :Resistivity; DIrect Current; Monitoring; Groundwater; Contaminant; Tracer Test; Geophysics;

    Sammanfattning : The most common method of monitoring and mapping groundwatercontaminants is to extract and analyse a number of groundwatersamples from wells in the investigation area. However, thereare a number of limitations with this type of point-wiseinvestigation, as it is hard to acquire an adequate picture ofa heterogeneous and anisotropic subsurface using a fewpoints.
