  1. 1. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Evelina Hansson; [2023-06-21]
    Nyckelord :benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

    Sammanfattning : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). LÄS MER

  3. 2. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Tamina Kabir; [2023-03-08]
    Nyckelord :;

    Sammanfattning : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. LÄS MER

  4. 3. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Kristoffer Wilson; [2023]
    Nyckelord :Vibrometer; Biotremology; Imidacloprid; Ants;

    Sammanfattning : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. LÄS MER

  5. 4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Hana Faulds; [2023]
    Nyckelord :Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  7. 5. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

    Master-uppsats, Uppsala universitet/Statistik, AI och data science

    Författare :Axel Sandstedt; [2023]
    Nyckelord :density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

    Sammanfattning : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. LÄS MER
