  1. 1. Mini-Jet Production in Proton-Antiproton Interactions and Particle Production in Heavy-Ion Collisions

    Detta är en avhandling från Experimental High-Energy Physics

    Författare :Haiqiao Wang; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proton antiproton interaction; Quark-gluon plasma; dynamical fluctuation; intermittency; limiting fragmentation; intranuclear cascading; target fragmentation; heavy-ion collision; image processing; mini-jet; Nuclear physics; Kärnfysik; Fysicumarkivet A:1997:Wang;

    Sammanfattning : The thesis is based on the data analysis and detector development of the EMU01/CERN, E863/BNL and UA1/CERN experiments. Particle fluctuations are studied with the scaled factorial moments in the fragmentation region of oxygen-induced emulsion interactions from 3.7 to 200 A GeV. LÄS MER

  2. 2. Effects of Past and Current Land Use on Biodiversity: from a semi-natural grassland on Öland (Sweden) to a European perspective

    Detta är en avhandling från Tryckeriet i E-huset, Lunds universitet

    Författare :Marie Vandewalle; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecosystem services; bioindicators; land-use history; Biodiversity; semi-natural grasslands conservation; habitat fragmentation; functional diversity;

    Sammanfattning : Concerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecosystem services. LÄS MER

  3. 3. Simulations of Biomolecular Fragmentation and Diffraction with Ultrafast X-ray Lasers

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christofer Östlin; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; X-ray imaging; Single particle imaging; Computer simulation; Radiation damage; Molecular dynamics; Diffraction theory; Coulomb explosion; Sample heterogeneity; Diffractive noise; XFEL; SPI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Studies of biomolecules have recently seen substantial developments. New X-ray lasers allow for high-resolution imaging of protein crystals too small for conventional X-ray crystallography. Even structures of single particles have been determined at lower resolutions with these new sources. LÄS MER

  4. 4. Spatial complexity and fit between ecology and management Making sense of patterns in fragmented landscapes

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

    Författare :Arvid Bergsten; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Connectivity; Conservation; Dispersal; Ecological knowledge; Ecology; Forest; Fragmentation; Graph theory; Institutional fit; Landscape; Management; Metapopulation; Municipal ecologist; Network; Planning; Protected area; Scale mismatch; Social-Ecological; Urban; Wetland; Natural Resources Management; naturresurshushållning;

    Sammanfattning : Avoiding the negative effects of habitat fragmentation on biodiversity is especially challenging when also the management institutions are spatially and administratively distributed. This doctoral thesis introduces five case studies that investigate ecological, social and social-ecological relations in fragmented landscapes. LÄS MER

  5. 5. Stochastic systems with locally defined dynamics

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Anton Muratov; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; point process; sequential adsorption; stopping set; random measure; Polya urn; convergence of empirical measures; bit flipping; recurrence; mixing times;

    Sammanfattning : This thesis considers two large classes of models related to the dynamical point processes. The first is the locally interactive sequential adsorption, or LISA, models. LÄS MER
