  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. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Ali Maghsoodpoor; [2022]
    Nyckelord :Metal-organic Framework; gas sorption;

    Sammanfattning : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. LÄS MER

  3. 3. Suzuki reactions in novel liquids

    Master-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Nazanin Hassanzadeh; [2021]
    Nyckelord :Suzuki coupling reaction; ni-DES; HPLC; TLC;

    Sammanfattning : Non-ionic deep eutectic solvent (ni-DES) possesses various advantages such as good solvation, biodegradability, and non-toxicity which makes it a perfect and environmentally friendly solvent for organic synthesis. A Pd (OAc)2 catalyzed, Suzuki reaction of aryl bromide and N-heteroaryl halide with arylboronic acid in green and novel solvent (ni-DES) is described. LÄS MER

  4. 4. Livestock-MRSA in Danish Pig Farms

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Mona Tykesson Klubien; [2021]
    Nyckelord :GIS; epidemiology; MRSA; Denmark; pig production; logistic regression; Earth and Environmental Sciences;

    Sammanfattning : This study looks at factors contributing to LA-MRSA prevalence in Danish pig farms. LA-MRSA is a pathogenic bacteria that are resistant to methicillin (penicillin) and tetracycline antibiotics found in livestock such as pigs, poultry and cattle. LÄS MER

  5. 5. Relating the impacts of regenerative farming practices to soil health and carbon sequestration on Gotland, Sweden

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Laerke Daverkosen; Alena Holzknecht; [2021]
    Nyckelord :regenerative agriculture; soil health; carbon sequestration; Gotland Sweden ;

    Sammanfattning : Land degradation, greenhouse gas emissions and biodiversity loss through agriculture are some of the greatest challenges we are facing today. Fertile and productive soils are the basis of life on this planet and need to be protected and restored to support a growing population and lower negative impacts of climate change. LÄS MER
