    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Josef Utterfors; Adam Tegenfeldt; [2022]
    Keywords : Fire; wall; corner; hot gas layer; flame height; plume temperature; Technology and Engineering;

    Abstract : The topic of fires in corners and along walls has been studied previously, however, two different studies conducted in 1987 and 2018 respectively, produced conflicting results regarding plume temperature for fires along walls, as well as hot gas layer temperature for both fires in corners and along walls. This thesis seeks to add data and clarification about fires in corners and along walls. READ MORE

  4. 3. Elevated Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Kseniia Polukhina; [2016]
    Keywords : fire position; elevation; fire development; Technology and Engineering;

    Abstract : The primary objective of the present study is to evaluate the effect of the fire source elevation on the main fire parameters, by implementing laboratory experiments. In modern Fire Safety Engineering practice, it is often assumed that fire always commences at the floor level. However, it is not always the case. READ MORE

  5. 4. Mortalitet och skottskjutningsförmåga hos ek (Quercus robur) efter brand

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Hanna Backman; [2004]
    Keywords : mortalitet; skottskjutningsförmåga; quercus robur; ek; brand;

    Abstract : In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study consisted of two separate field tests; in the first, two 300 m2- plots in western oak dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height).

  6. 5. The effect of different disturbance treatments on tree production, competition, shortroot presence and ectomycorrhizal colonisation in Ericaceae-feathermoss boreal forests

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Björn Eriksson; [2003]
    Keywords : disturbance; tree seedlings; mycorrhiza; feathermoss; boreal forest;

    Abstract : In many northern boreal stands, forest floor vegetation constitutes a considerable part of total biomass and production, and consequently is likely to be critical in determining tree seedling growth. This study was conducted in a greenhouse with seedlings grown in intact soil profiles consisting of a minimum coverage of 90% of Pleurozium schreberi and 30% of Vaccinium myrtillus vegetation.
