  1. 1. Amine Transaminases in Biocatalytic Amine Synthesis

    Författare :Henrik Land; Per Berglund; Helen C. Hailes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amine Transaminase; Biocatalysis; Transamination; Reductive Amination; Enzyme; Enzyme Engineering; Equilibrium Displacement; Screening; Enzyme Stability; Bioteknologi; Biotechnology;

    Sammanfattning : The use of enzymes, nature´s own catalysts, both isolated or as whole cells to perform chemical transformations is called biocatalysis. As a complement to classical chemical catalysis, biocatalysis can be an environmentally friendly and more economical option in the production and synthesis of chemicals. LÄS MER

  3. 3. Land Use Conflicts between Agriculture and Energy Production : Systems Approaches to Allocate Potentials for Bioenergy and Agrophotovoltaics

    Författare :Daniel Ketzer; Peter Schlyter; Henrik Ny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energies; Geographic Information Systems; Agrophotovoltaics; Participatory technology development; Responsible Research and Innovation; Physical Geography; naturgeografi;

    Sammanfattning : The developments towards a bio-based economy and a renewable energy-based power supply require thorough assessments of feedstocks and frameworks. In the past, political targets for increasing shares of renewable energies for combatting climate change have triggered direct land use changes (LUCs) and even indirect land use changes (iLUCs).

  4. 4. Svenska siffror : Nationell integration och identifikation genom statistik 1800–1870

    Författare :Henrik Höjer; Per Wisselgren; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History; Nationalism; history of statistics; nation building; representations; national identity; history of books; history of science; the public sphere; Tabellverket; Sweden 1800–1870; Historia; History subjects; Historieämnen; historia; History;

    Sammanfattning : The aim of this thesis is to study the nation building process in Sweden. How was a national identity constructed? One answer to this question is that statistical representations of the nation played a major role to shape a visual image of Sweden. Statistical books became a popular genre during the nineteenth century. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Alpha-diversity; Beta-diversity; Biological pest control; Canopy cover; Connectivity; Ecosystem function; Fleshy fruits; Forest edge; Forest management; Forest specialist species; Fragmentation; Functional diversity; Gamma-diversity; Grassland specialist species; Green infrastructure; Habitat amount hypothesis; Island biogeography; Midfield islets; Plant diversity; Plant-pollinator interaction; Pollination; Remnant habitat; Seed predation; Small habitats; Species richness; Structural heterogeneity; Physical Geography; naturgeografi;

    Sammanfattning : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. LÄS MER
