  1. 1. Remote sensing of supra-glacial lakes on the west Greenland Ice Sheet

    Författare :A. Malin Johansson; Ian A. Brown; Peter Jansson; Johan Kleman; Andreas Ahlstrøm; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Supra-glacial lakes; Greenland Ice Sheet; Ice melting; Remote sensing; SAR; MODIS; Time-series analysis; Physical Geography; naturgeografi;

    Sammanfattning : The Greenland Ice Sheet is the largest ice sheet in the northern hemisphere. Ongoing melting of the ice sheet, resulting in increased mass loss relative to the longer term trend, has raised concerns about the stability of the ice sheet. Melt water generated at the surface is temporarily stored in supra-glacial lakes on the ice sheet. LÄS MER

  2. 2. Temporal and spatial dynamics in subarctic peat plateaus and thermokarst lakes

    Författare :A. Britta K. Sannel; Peter Kuhry; Peter Jansson; Ian A. Brown; Serge Payette; Stockholms universitet; []
    Nyckelord :Peatlands; permafrost; subarctic; peat plateau; thermokarst lake; macrofossil analysis; carbon nitrogen ratio; peat accumulation; carbon accumulation; remote sensing; binary encoding; time-series analysis; naturgeografi; Physical Geography;

    Sammanfattning : Permafrost peatlands are widespread at high northern latitudes and are important soil organic carbon reservoirs. A future warming in these areas, as suggested by global climate models, can cause thawing and increased ground subsidence (thermokarst), resulting in changes in surface hydrology and ecosystem functioning.

  3. 3. Paradoxen (s)om entreprenörskap : En romantisk ironisk historia om ett av-vikande entreprenörskapande

    Författare :Elisabeth Jansson; Björn Bjerke; Magnus Klofsten; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Entrepreneurship; entrepreneurial process; art; culture; creativity; creation; romantic irony; rhetoric analysis; narrative approach; metaphor; irony; paradox; anomaly; Business studies; Företagsekonomi; Business Administration; företagsekonomi;

    Sammanfattning : The aim of this thesis is to embrace entrepreneurship as a paradox and to additionally show how an anomaly can be the foundation as well as the energy for the paradoxical, entrepreneurial process. The empirical focus is on the creative industry, in which the intimate connection between entrepreneurship, enterprise, art, culture and creativity has been illustrated and accounted for. LÄS MER

  4. 4. High Performance Adaptive Finite Element Methods : With Applications in Aerodynamics

    Författare :Niclas Jansson; Johan Hoffman; Johan Jansson; Vincent Heuveline; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The massive computational cost for resolving all scales in a turbulent flow makes a direct numerical simulation of the underlying Navier-Stokes equations impossible in most engineering applications. Recent advances in adaptive finite element methods offer a new powerful tool in Computational Fluid Dynamics (CFD). LÄS MER

  5. 5. Effects of Simulated Recycling on Polyolefin Materials

    Författare :Anna Jansson; Anna L. Jansson; Chalmers University of Technology; []
    Nyckelord :recycling; oxidation; degradation; polyolefins;

    Sammanfattning : Production and handling of waste is a matter of concern in most countries, and one way to reduce the amount of waste is recycling. Since synthetic polymers are made from non- renewable resources and are used in large amounts, often for short periods of time, they should be recycled in a sustainable society. LÄS MER
