profiling the Spatial Concentration of allethrin and piperonyl butoxide using passive sorptive sampling and thermal desorption capillary gc ms
Chemosphere, 2008Co-Authors: Koen Desmet, Nathalie De Coensel, Tadeusz Gorecki, Pat SandraAbstract:Spatial Concentration distribution of a chemical in an indoor environment is an important factor in the evaluation of chemical nuisances. However, straightforward techniques for the determination of this distribution are not very common and usually limited in their application. Sorptive sampling using polydimethylsiloxane-coated stir bars and the combination of active and diffusive sampling were shown to allow uncomplicated Spatial Concentration profiling of multiple compounds in an indoor environment. The validity of the approach was demonstrated in the analysis of the Spatial Concentration distribution of a pyrethroid insecticide in a common bedroom. The relative Concentrations of allethrin and piperonyl butoxide were profiled throughout the room upon the application of an insecticide vaporizer.

the nature of starbursts iii the Spatial distribution of star formation
The Astrophysical Journal, 2012Co-Authors: Kristen B W Mcquinn, Evan D Skillman, Julianne J Dalcanton, John M Cannon, Andrew E Dolphin, Jon Holtzman, Daniel R Weisz, Benjamin F WilliamsAbstract:We map the Spatial distribution of recent star formation over a few Multiplication-Sign 100 Myr timescales in 15 starburst dwarf galaxies using the location of young blue helium burning stars identified from optically resolved stellar populations in archival Hubble Space Telescope observations. By comparing the star formation histories from both the high surface brightness central regions and the diffuse outer regions, we measure the degree to which the star formation has been centrally concentrated during the galaxies' starbursts, using three different metrics for the Spatial Concentration. We find that the galaxies span a full range in Spatial Concentration, from highly centralized to broadly distributed star formation. Since most starbursts have historically been identified by relatively short timescale star formation tracers (e.g., H{alpha} emission), there could be a strong bias toward classifying only those galaxies with recent, centralized star formation as starbursts, while missing starbursts that are Spatially distributed.

the age of extremes concentrated affluence and poverty in the twenty first century
Demography, 1996Co-Authors: Douglas S MasseyAbstract:Urbanization, rising income inequality, and increasing class segregation have produced a geographic Concentration of affluence and poverty throughout the world, creating a radical change in the geographic basis of human society. As the density of poverty rises in the environment of the world’s poor, so will their exposure to crime, disease, violence. and family disruption. Meanwhile the Spatial Concentration of affluence will enhance the benefits and privileges of the rich. In the twenty-first century the advantages and disadvantages of one’s class position will be compounded and reinforced through ecological mechanisms made possible by the geographic Concentration of affluence and poverty, creating a deeply divided and increasingly violent social world.
