  1. 1. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Tsai-wei Tang; [2022-01-26]
    Nyckelord :N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Sammanfattning : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. LÄS MER

  2. 2. Empowering Smallholder Farmers to Achieve Food Sovereignty Through Soil-Less Agriculture

    Magister-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Abhijith Nag Balasubramanya; Fathimath Zainy Shaafiu; [2022]
    Nyckelord :Food access; food sovereignty; food security; agriculture; alternative agriculture; aeroponics; hydroponics; aquaponics; empowerment; power; smallholder farmers; vertical farming.;

    Sammanfattning : This study explores the question of how soil-less agriculture through hydroponics, aeroponics, and aquaponics can empower smallholder farmers to achieve food sovereignty as portrayed in documentaries. It addresses the power imbalance between large corporations and smallholder farmers in the traditional agriculture industry. LÄS MER

  3. 3. Prototyping of an automated cyclic Neutron Activation Analysis setup

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

    Författare :Cornelius Maurer; [2022]
    Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

    Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER

  4. 4. Naturalistisk plantering i staden : ett alternativ till klippta gräsytor i en trafikerad miljö?

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Elsa Kinch; [2022]
    Nyckelord :naturalistiska planteringar; hållbar stadsutveckling; urbana planteringar; gräsytor; trafikerad miljö;

    Sammanfattning : Den urbana expansionen som forskarna räknar med kommer att vara den största och snabbaste i mänsklighetens historia. Samtidigt som en förtätning av staden sker har artdiversitet minskat. LÄS MER

  5. 5. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joakim Edlund; [2022]
    Nyckelord :Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Sammanfattning : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. LÄS MER
