  1. 1. Förekomst av snöskytte i hyggesfria metoden schackrutehuggning i Västerbotten

    University essay from SLU/School for Forest Management

    Author : Jenny Johansson; [2024]
    Keywords : phacidium infestans; kontinuitetsskogsbruk; Norrland;

    Abstract : Skogen är och har länge varit en viktig resurs för länet Västerbotten och den står för cirka 14 procent av den produktiva skogsmarksarealen i Sverige. Skogen i Västerbotten har brukats sedan medeltiden från småskaligt hushållsbehov till storskaligt skogsbruk i modern tid. READ MORE

  3. 2. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alexina Brännlund; [2023]
    Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  4. 3. Identifying training needs for the implementation of Continuous Cover Forestry in Sweden

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

    Author : Lydia Kruse; [2023]
    Keywords : Marteloscope; Thinning type; Conitnuous Cover Forestry; Frame tree; Human behaviour;

    Abstract : In recent decades, continuous cover forestry (CCF) has been (re-)discovered as an important toolbox for promoting biodiversity, helping to deliver a range of ecosystem goods and services as well as to satisfy the needs of various stakeholders. CCF is based on ecological principles and one of its most important tenets is the abandonment of large-scale clearfelling. READ MORE

  5. 4. A comparison of thinning programmes in European beech (Fagus sylvatica L.) based on permanent plots in Southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Delphine Anni Fortu; [2023]
    Keywords : beech; volume growth; diameter development; thinning programme; quality traits;

    Abstract : The present study investigated 7 thinning experiments in beech which were established in 1971. The purpose was to compare two thinning programmes with different thinning intervals. The programmes (A and B) were designed according to yield tables by Carbonnier (1971). The experimental plots have been measured regularly in 5 to 10 years intervals. READ MORE

  6. 5. Forced response numerical investigation of a transonic compressor rotor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE
