  1. 1. The role of WRKY 15 in xylem development and salt response in Arabidopsis thaliana

    Kandidat-uppsats, SLU/Dept. Of Plant Biology

    Författare :Johanna Karlsson; [2023]
    Nyckelord :WRKY15; VND; xylem; salinity; water availability;

    Sammanfattning : Xylem is a water-conducting tissue in vascular plants, that absorbs water from the roots and distributes it throughout the compartments, providing the plant with essential water and nutrients for its cellular processes. The xylem, divided into protoxylem and metaxylem, develops differently according to the various abiotic circumstances, in which transcription factors have a crucial role. LÄS MER

  3. 2. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Carl Holmquist; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Sammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER

  4. 3. Xylem Water Filtration

    Master-uppsats, Lunds universitet/Industridesign

    Författare :David Wenner; [2023]
    Nyckelord :Technology and Engineering; Arts and Architecture;

    Sammanfattning : This project explored the usage and effectiveness of a natural water filtration system using xylem from Picea Abies, or Norway Spruce. The project is concentrated on the region of southeast and south Asia where people suffer from water contamination, providing a concept of a water filter with comprehensive protection against waterborne diseases.

  5. 4. Utveckling av vändprocess vid montering av en pump

    M1-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Filip Björklund; Roderik Svensson; [2022]
    Nyckelord :Produktutveckling; Pumpar; Montering; Vändprocess; Masscentrum; Maskinelement; Snäckväxel; Vridmoment; Rullager;

    Sammanfattning : På industriföretag idag är det svårt att komma ifrån hantering av tunga lyft. När tunga lyft eller rotationer sker på företag står säkerhet och ergonomi i fokus. Det finns olika regler att förhålla sig till på olika företag. LÄS MER

  7. 5. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Fayez Altabbaa; [2022]
    Nyckelord :Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Sammanfattning : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. LÄS MER
