  1. 1. Tree Species Impact on Forest Fire Spread Susceptibility in Sweden

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

    Författare :Sara Sharon Jones; [2023]
    Nyckelord :Geography; GIS; Physical Geography; Forest Fire; Forest Fire Susceptibility; Sweden; logistic regression modelling; Earth and Environmental Sciences;

    Sammanfattning : Klimatförändringar förväntas leda till längre brandperioder och ökad brandrisk. I Sverige, där homogen produktionsskog utgör största delen av landskapet, finns ett behov av bättre förståelse för skogens mottaglighet för bränder för att kunna mildra risker. LÄS MER

  2. 2. Performance of joints for glued laminated timber exposed to the ISO fire temperature curve

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jesus Gil; [2021]
    Nyckelord :Glued laminated Timber; Structural fire engineering; Fire performance; standard ISO fire curve; Joints; Technology and Engineering;

    Sammanfattning : As society becomes more ecologically conscious there is a push toward the use of materials with a smaller environmental burden, one of these materials is glulam (GLT), which has gained a lot of traction in recent years not only for ecological reasons but for its ease in manufacture, transport, noise dampening, etc. The focus of this project was to evaluate the influence of different joint configurations on the fire performance of glulam members.

  3. 3. Developing a technique for combining light and ultrasound for deep tissue imaging

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Meng Li; [2018]
    Nyckelord :UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Sammanfattning : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. LÄS MER

  4. 4. Asiatisk svartbjörn, Ursus thibetanus, i Kinas gallindustri

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Sophia Panofsky; [2018]
    Nyckelord :asiatisk svartbjörn; Ursus thibetanus; gallfarm;

    Sammanfattning : Björngalla används inom traditionell kinesisk medicin till att behandla en rad olika sjukdomar och tillstånd från halsont till frakturer, syfilis och cancer. Tjuvjagade vilda björnar var källan till den björngalla som användes i traditionell kinesisk medicin innan 1980. LÄS MER

  5. 5. The effect of ecological forest restoration on bumblebees (Bombus spp.) in the boreal forest

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Raisja Spijker; [2018]
    Nyckelord :bumblebee; Bombus spp.; forest restoration; abundance; species richness; species composition; boreal forest;

    Sammanfattning : Insect pollinators are an important part of biodiversity, yet the number of pollinating insects is declining all over the world. Of all the wild plant species about 80% are reliant on insect pollinators, with bees being most important. One of the main causes behind the decline of insect pollinators is the loss and fragmentation of habitats. LÄS MER
