2. 1. Variations in Functional Lateralization

   Author : Peter E Wendt; Institutionen för psykologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; posterior association cortex; prefrontal; DLPFC; regional cerebral blood flow; normal subjects; lateralization; asymmetry; performance; creativity; Neurology; neuropsychology; neurophysiology; cognitive; ethanol; activation; visual stimulation; functional; verbal; divergent; spatial; Neurologi; neurofysiologi; neuropsykologi;

   Abstract : The general aim of this thesis was to study asymmetric activation of the neocortex in normal subjects, using the rCBF technique and different cognitive tasks. The aim was also to study individual and group variations of asymmetric activation, as well as factors pertaining to these variations. The thesis is based on four investigations. READ MORE

4. 2. Patterns of co-presence : Spatial configuration and social segregation

   Author : Ann Legeby; Lars Marcus; Laura Vaughan; Daniel Koch; Julienne Hanson; KTH; []
   Keywords : HUMANIORA; HUMANITIES; co-presence; spatial configuration; public space; urban segregation; urban design; public life; spatial affordance;

   Abstract : This thesis notes that there is a lack of systematic research investigating segregation patterns based on how public space is used and frequented by citizens. In order for understanding of urban segregation to reach beyond residential segregation, the extent to which public space facilitates co-presence between social groups is a key issue. READ MORE

6. 4. Nitrogen removal in treatment wetlands : Factors influencing spatial and temporal variations

   Author : Sofia Kallner Bastviken; Karin Sundblad-Tonderski; Jos Verhoeven; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wetlands; denitrification; macrophytes; nitrogen; nitrification; model; treatment wetlands; potential denitrification; Biology; Biologi;

   Abstract : Decreasing the nitrogen transport from land to surrounding seas is a major task throughout the world to limit eutrophication of the coastal areas. Several approaches are currently used, including the establishment of wetlands, to decrease the transport of nitrogen. READ MORE

7. 5. Persistent organic pollutants in the atmosphere - spatial and temporal variations

   Author : Cecilia Backe; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical and temperate regions; global transport; temperature; latitudinal fractionation; fugacity; soil organic matter; soil-air exchange; washout ratio; rain; precipitation; atmosphere; spatial and temporal variations; DDT; PCB; persistent organic pollutants; polychlorinated biphenyls; Environmental chemistry; Miljökemi; Ecology; Ekologi; Chemistry; Kemi;

   Abstract : In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region.
