  1. 21. Analysis of Turbulent Flows-From Chaos to Structure

    Författare :Farideh Ghasempour; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; Vortex dynamics; Turbulence; Flow visualization; Vortex statistics; Coherent structure;

    Sammanfattning : The development of models for several phenomena occurring in turbulent single and multi-phase flows requires improved description and quantification of turbulent structures. Phenomena such as, for example, mixing, coalescence and break-up, are often fast and nonlinear. LÄS MER

  3. 22. Making Head or Tail of the Hippocampus : A Long-Axis Account of Episodic and Spatial Memory

    Författare :Jonas Persson; Hedvig Söderlund; Tomas Furmark; Asaf Gilboa; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; fMRI; episodic memory; spatial memory; gender differences; Psychology; Psykologi;

    Sammanfattning : While episodic and spatial memory both depend on the hippocampus, opposite gender differences in these functions suggest they are partly separate, with different neural underpinnings. The anterior and posterior hippocampus differ  in structure and whole-brain connectivity, and studies point to the posterior hippocampus being more involved in spatial memory while the anterior hippocampus’ role in episodic memory is less clear.

  4. 23. Spatial and temporal ecology of oak-associated fungal communities

    Författare :Maria Faticov; Ayco Tack; Peter Hambäck; Paula Baptista; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic and biotic forces; climate warming; community ecology; foliar fungal community; host genotype; plant microbiome; powdery mildew; seasonal dynamics; warming-by-genotype interaction; Quercus robur; soil fungal community; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Plants host a large diversity of microorganisms, which includes fungi, bacteria and archaea. Among these, fungi are highly diverse, and known to play a vital role in plant health and in regulation of the essential ecosystem functions. LÄS MER

  5. 24. Vestiges of urban spirit : Isfahan's urban fabric through socio-spatial transformations

    Författare :Mohammad Sarraf; Reza Kazemian; Sussan Babaie; Ali Madanipour; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Isfahan; Urban Fabric; Socio-spatial Communication; Urban Identity; Urban Transformation; Urban Renewal; Urban Form; Urban Design; اصفهان ، طراحی شهری ، فرم شهری ، دگرگونی های کالبدی ، هویت شهری ، بازسازی شهری; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : The city of Isfahan, one of the most historic urban settlements in Iran, has undergone dramatic socio-spatial transformations during the recent decades, beginning with the modernization programs of the 1920s. While the urban structure of Isfahan was the outcome of a process over centuries of incremental evolution, a new mode of place making and street patterns was imposed on the historic fabric of the city within the space of only a few decades.

  7. 25. Modeling and improving Spatial Data Infrastructure (SDI)

    Författare :Ehsan Abdolmajidi; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial Data Infrastructure; System Dynamics; Fuzzy Logic; Data integration; Pattern detection; Resource Description Framework RDF ; Ontology;

    Sammanfattning : Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. LÄS MER
