  1. 1. Long and short term effects of stump harvesting on saproxylic beetles and ground flora

    Författare :Jon Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Research on the effects from forest management on biodiversity has been going on for decades but still there are many questions unanswered. With every introduction of a new forestry method there is risk for increased pressure on biodiversity. The harvesting of low stumps left after final harvesting is a relatively new method used in forestry. LÄS MER

  3. 2. Environmental Impact Assessment using Production Flow Simulation

    Författare :Jon Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Event Simulation; Life cycle assessment; Environmental impact assessment;

    Sammanfattning : A higher-level perspective for production engineers and enables detailed assessment of dynamic manufacturing systems environmental impact at a system level. By using simulation, the simulation engineer enables to understand how minor adjustments affect the system. LÄS MER

  4. 3. Controlling the Formation and Stability of Alumina Phases

    Författare :Jon Martin Andersson; Ulf Helmersson; Eric Kay; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin films; alumina; magnetron sputtering; phase stability; density functional theory; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : In this work, physical phenomena related to the growth and phase formation of alumina, Al2O3, are investigated by experiments and computer calculations. Alumina finds applications in a wide variety of areas, due to many beneficial properties and several existing crystalline phases. LÄS MER

  5. 4. Low-temperature growth of alumina

    Författare :Jon M. Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Physical phenomena related to the growth of alumina, A12O3, are investigated by experiments and ab initio calculations. Alumina is a well studied material with applications in a variety of areas, due to its many beneficial properties. LÄS MER

  7. 5. Managing the Urban Greens : Maintaining ecological functions in human dominated landscapes

    Författare :Erik Andersson; Thomas Elmqvist; Jon Sadler; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Natural Resources Management; naturresurshushållning;

    Sammanfattning : At the core of this thesis lie two realisations: First, like other ecosystems, those in urban landscapes provide humans with a number of ecosystem services, some recognized while others are not. Second, in cities just as in other intensively used social-ecological systems, management is of central importance. LÄS MER
