  1. 1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Patricia Salén; [2024]
    Nyckelord :Ectomycorrhiza; drought; Suillus;

    Sammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER

  3. 2. Var kommer intresset till hyggesfritt skogsbruk ifrån?

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Andreas Bohman; Eskil Calmered Tersmeden; [2024]
    Nyckelord :skogsvärden; intervjustudie; enkätundersökning;

    Sammanfattning : Hyggesfritt skogsbruk är något som mer och mer ses som ett intressant alternativ för skogsägare. Det diskuteras hyggesfritt skogsbruk i olika debattforum, på nyheter och i politiska sammanhang. Även hos de väletablerade skogsföretagen pågår diskussioner om hyggesfritt. LÄS MER

  4. 3. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  5. 4. Förskollärares uppfattningar om skogen som lärmiljö : En kvalitativ studie om förskollärares olika uppfattningar om skogen som lärmiljö

    Uppsats för yrkesexamina på grundnivå, Karlstads universitet/Fakulteten för humaniora och samhällsvetenskap (from 2013)

    Författare :Sara Wikström; Julia Strand; [2024]
    Nyckelord :Forest; gross motor skills; perceptions; phenomenography; preschool; Fenomografi; förskola; grovmotorik; skogen; uppfattningar;

    Sammanfattning : The study will be based on a qualitative method with a focus on describing seven preschool teachers' different perceptions of the forest as a learning environment for all age groups in preschool. Further in this work, we want to contribute knowledge about the forest's possibilities for gross motor development, learning and influence for all children in preschool. LÄS MER

  7. 5. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Zeyuan Wu; [2024]
    Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

    Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.
