  1. 1. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  3. 2. A Machine Learning Approach for Comprehending Cosmic Expansion

    Master-uppsats, KTH/Fysik

    Författare :Ludvig Doeser; [2021]
    Nyckelord :Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Sammanfattning : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. LÄS MER

  4. 3. Somliga gator är somriga gator - En jämförande studie av Sveriges sommargågator

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

    Författare :Vera Esaiasson; [2019]
    Nyckelord :Sommargågator; temporär urbanism; tillfällig urbanism; sommarga-tor; flexibel urbanism; tillfällig anvädning; Technology and Engineering;

    Sammanfattning : A summer street is created by temporarily closing the car traffic on a street during the summer months. The pedestrians get access to the entire street and the liberated space can be used for activities, greenery, benches, bike parking, art and by restaurants. During recent years major cities have made the concept known to the general public. LÄS MER

  5. 4. 20,000 14C Years of Climate and Environmental Change in Europe : A Coleopteran-based Reconstruction with an Anthropocenic Focus

    Master-uppsats, Umeå universitet/Miljöarkeologiska laboratoriet

    Författare :Misha Enayat; [2015]
    Nyckelord :archaeology; beetle; Anthropocene; climate; coleoptera; coleopteran; Bugs; BugsCEP; Vera Hypothesis; Holocene; database; Quaternary; entomology;

    Sammanfattning : This thesis builds on the work of previous coleopteran-based climatic reconstructions to recreate the environment and climate of the last 20,000 14C years of northwest Europe using the data and methods available within the Bugs Coleopteran Ecology Package, and aims to assess the ability of the BugsCEP results to provide information regarding events and anthropogenic changes on environment during the Anthropocene. Samples and data from 134 sites across northwest Europe and the British Isles were included in this study. LÄS MER

  7. 5. High Forest or Wood Pasture: A model of Large Herbivores' impact on European Lowland Vegetation

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Xuefei Yao; [2010]
    Nyckelord :Vera hypothesis; wood pasture; high forest; gap model; herbivore impact; long-term landscape model;

    Sammanfattning : Natural forest dynamics is a foundational topic of forest science. A new Wood Pasture hypothesis considering large herbivore as driving force in forest ecosystem is now challenging the traditional High Forest hypothesis, in which vegetation is regarded as main driving force.
