  1. 1. CONTESTING URBAN PUBLIC SPACE AS COMMONS - A study on the common usage of public parks in Barcelona-Sants

    University essay from Göteborgs universitet/Institutionen för globala studier

    Author : Julia Neidig; [2020-02-18]
    Keywords : Urban Commons; public space; spaces of in-betweenness; observation; socio-spatial analysis;

    Abstract : Urbanisation is one of the major trends in globalisation. An influx of heterogenous urban dwellers to a densely built urban environment contains potential for conflicts. With increasing heterogeneity, public space in cities becomes the site of multicultural confrontation. READ MORE

  2. 2. Spatial Heterogeneity of Weather impacts on Cycling Flows within Gothenburg, Sweden - A Geographic Framework for Local Pattern Analysis

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Filip Olsson; [2019-10-25]
    Keywords : spatial heterogeneity; cycling; weather; local climate zones; explorative GIS;

    Abstract : Background: In the past decade, the phenomenon of spatial heterogeneity has started to gaintraction in studies of cycling and weather. Cycling is usually the mode of transportation that ismost affected by inclement weather and the scientific consensus about how weather impactscycling behaviour on a general scale is for the most part well-established.

  3. 3. Investigating Gas Turbulence in Galactic Discs

    University essay from Lunds universitet/Astronomi

    Author : Timmy Ejdetjärn; [2019]
    Keywords : galaxies; gas; turbulence; interstellar medium; star formation; feedback; gravitational instability; local; high redshift; Physics and Astronomy;

    Abstract : The interstellar medium of both local and distant disc galaxies is observed to be supersonically turbulent and the turbulent motion of the gas is thought to be important for galaxy formation and evolution, particularly as a key ingredient for star formation. Consequently, this generates a striking relation between the star formation rate (SFR) and gas velocity dispersion ($\sigma_{\rm g}$; a measurement on the level of turbulence). READ MORE

  4. 4. Adaptive Evolution of Resource Use, Phenotypic Diversity, and Productivity of Phytoplankton Communities

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Hellekant; [2019]
    Keywords : Adaptive Dynamics; phenotype; phytoplankton; plankton; BEF; Biodiversity; diversity; Spatial modeling; Ecosystem function; Evolution; Diversity;

    Abstract : There is growing concern that the worldwide loss in biodiversity will harm the stability of the ecosystems, and thereby, the carrying capacity and critical ecosystem services the biosphere provides. Phytoplankton (microalgae) in lakes and oceans are arguably the most important primary producers. READ MORE

  5. 5. Spatial Frequency-Based Objective Function for Optimization of Dose Heterogeneity in Grid Therapy

    University essay from Stockholms universitet/Fysikum

    Author : Fredén Emil; [2019]
    Keywords : Radiotherapy; Dose Optimization; Objective function; Dose Heterogeneity; Proton Grid Therapy; Spatially Fractionated Radiotherapy; SFRT;

    Abstract : In this project we introduced a spatial frequency-based objective function for optimization of dose distributions used in spatially fractionated radiotherapy (also known as grid therapy). Several studies indicate that tissues can tolerate larger mean doses of radiation if the dose is delivered heterogeneously or to a partial volume of the organ. READ MORE
