1. 1. Mängden död ved i värdekärnor i Söderåsens nationalpark

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Gustav Thurell; [2024]
   Nyckelord :volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

   Sammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

3. 2. Föryngring med hägn : effekten av viltbete på självföryngrad ädellövskog i tre skånska naturreservat

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

   Författare :Håkan Ramberg; Kaj Sjöqvist; [2023]
   Nyckelord :Bokskog; naturlig föryngring; betesbegärlighet; viltbete; strukturförändring;

   Sammanfattning : Ädellövskogens artsammansättning styrs av flera naturliga processer, en av dessa processer är viltbete. Bete kan leda till att trädslagsfördelningen förändras och att föryngring blir problematiskt, speciellt i områden med stora viltstammar och för de mer betesbegärliga trädarterna. LÄS MER

4. 3. Survival of foodborne bacteria on wooden and plastic cutting boards - A laboratory protocol

   Master-uppsats, SLU/Dept. of Clinical Sciences

   Författare :Nicole Svärd; [2023]
   Nyckelord :foodborne bacteria; cutting board; bacterial survival; wood; plastic; laboratory protocol;

   Sammanfattning : The survival of foodborne bacteria on different cutting board materials has been studied and a functional laboratory protocol for further studies on the subject has been established. Six different bacteria, E. coli, S. aureus, L monocytogenes, S. LÄS MER

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

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

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

   Sammanfattning : 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. LÄS MER

7. 5. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Xinyi Wei; [2023]
   Nyckelord :Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

   Sammanfattning : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.
