  1. 1. Modelling Gas Flow Behaviour in Gas Atomizer

    Master-uppsats, KTH/Materialvetenskap

    Författare :Aravind Senan Vasanthasenan Reji; [2022]
    Nyckelord :Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Sammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  3. 2. Effects of “classical” vs. “dynamic” silviculture of sessile oak-dominated stands in terms of height, diameter increments and natural mortality

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Alexandru-Mihai Goia; [2020]
    Nyckelord :sessile oak; cleaning-respacing; thinning; stand silviculture; crop tree silviculture; mortality; growth; Romania;

    Sammanfattning : Traditional oak silviculture in Romania is associated with high labor costs and long rotation cycles which are imposed by current norms and regulations. A small-scale R&D project, consisting of a block with four plots of 200 m2, was established in 2001 in a 15-year old sessile oak-dominated stand. LÄS MER

  4. 3. Influence of climate and mixture effect on radial increment of European beech (Fagus sylvatica) in pure and mixed stands with Scots pine (Pinus sylvestris)

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jakub Szeptun; [2015]
    Nyckelord :European beech; Scots pine; radial increment; climate; mixed forest; stands age; dendrochronology; tree ring width;

    Sammanfattning : The main aim of this study was to investigate the trends of radial increment of European Beech (Fagus sylvatica L.) in pure stands and mixed stands with Scots pine (Pinus sylvestris L.). The study plots were located in Kivik and Tyringe in Skåne which is the southernmost region of Sweden. LÄS MER

  5. 4. 250 years of disturbance dynamics in a pristine old-growth Picea abies forest in Arkhangelsk region, north-western Russia : a dendrochronological reconstruction

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Tatiana Khakimulina; [2011]
    Nyckelord :Forest history; disturbance dynamics; canopy gap; old-growth forest;

    Sammanfattning : To describe the historical patterns of natural disturbance regimes in European borealforests we conducted a dendroecological study in a primeval old-growth sprucedominated stands and reconstructed the long-term dynamics of canopy disturbances.We treated the radial growth releases of individual sub-canopy trees as the majorindicator of sudden openings in the forest canopy.
