  1. 11. Freden, friköpen och järnplogarna. Drivkrafter och förändringsprocesser under den agrara revolutionen i Halland 1700 - 1900

    Författare :Pablo Wiking-Faria; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; agricultural revolution; motivating forces; Halland; Sweden; history; northwestern Europe; 18th century; 19th century; peasants; freeholders; bottom-up theory; estate inventories; agricultural tools; land reclamation; cultivation systems; enclosures; livestock;

    Sammanfattning : The thesis studies the agricultural revolution in the province Halland in southwestern Sweden. New tools, land reclamation, new cultivation systems, better livestock, enclosures and free holding during the period 1700-1900 are investigated. The source materials consist of estate inventories, land survey documents and present descriptions. LÄS MER

  2. 12. Seaweed as a sustainable source of food protein: maximizing seaweed protein content, protein recovery, and nutritional quality

    Författare :João Pedro Trigo; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; protein isolation; intestinal permeability; detergent; thermal water treatment; protein shift; wastewater; elemental compositional; macroalgae; gastrointestinal digestion; cultivation;

    Sammanfattning : This thesis focuses on utilizing seaweed, such as Saccharina latissima and Ulva fenestrata , as sustainable food protein sources to complement terrestrial protein currently limited by land and water supply. While seaweed holds promise, its protein content is lower than pulses and antinutrients reduce protein nutritional quality. LÄS MER

  3. 13. Seaweeds as a future protein source: innovative cultivation methods for protein production

    Författare :Kristoffer Stedt; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Saccharina latissima; Ulva fenestrata; Ulva intestinalis; Chaetomorpha linum; Cultivation conditions; Nitrogen content; Amino acids; Heavy metals; Food safety; Wastewater; Process water; Circularity; Blue economy;

    Sammanfattning : As the global population is projected to reach approximately 10 billion people by 2050, it is estimated that we will need to produce up to 60% more food compared to 2010. Although the current food production system contributes to 25% of greenhouse gas emissions worldwide, accounts for 70-80% of eutrophication and freshwater usage, and occupies half of all ice- and desert-free land, it fails to meet the global nutritional needs.

  4. 14. 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).

  5. 15. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Författare :Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. LÄS MER
