  1. 1. Skillnader mellan granindivider gällande initieringsfrekvens för somatisk embryogenes

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Josefine Björs; Jonathan Sjögren; [2023]
    Nyckelord :skogsträdsförädling; Picea abies; fröklonförökning;

    Sammanfattning : Gran (Picea abies) har länge varit ett viktigt trädslag för den svenska skogsnäringen. Skogsbruket står inför en oviss framtid och med ett alltmer ostadigt klimat behövs ett genetiskt material som kan klara dessa nya prövningar. LÄS MER

  3. 2. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jacob Johansson; [2023]
    Nyckelord :biochar; biomass; heat release rate; reaction-to-fire;

    Sammanfattning : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. LÄS MER

  4. 3. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Olina Öhrn; [2023]
    Nyckelord :ZnO; zinc oxide; cone calorimeter; wood; reaction-to-fire;

    Sammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER

  5. 4. Actin filaments as an indicator of impaired neuronal differentiation mediated by disruption of the retinoic acid signalling pathway

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Hanin Salloum; [2022]
    Nyckelord :Retinoic acid; actin; cytoskeleton; neural progenitor C17.2 cells; neuron; Coronin 1C; Cdc42 Cdc42 effector protein 4 gene ; Fn1 Fibronectin ; Wnt pathway.;

    Sammanfattning : Retinoic acid (RA) is a well-known neurodevelopmental signaling molecule. It is reported to induce effects on neurite formation in differentiating neurons and to interfere with the actin cytoskeleton. Therefore, this project aimed to investigate the mechanisms behind effects of RA on the actin cytoskeleton of developing neurons using the C17. LÄS MER

  7. 5. A spatial analysis of Norwegian spruce cone developmental stages

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Alina Orozco; [2020]
    Nyckelord :;

    Sammanfattning : The Norway spruce Picea abies is an economically important export to the Swedish economy. There are a number of environmental and endogenous factors that impact the generation time of this species meaning that it can take 20-25 years for a tree to mature. LÄS MER
