  1. 1. Pheromone-based mating disruption to control Spodoptera frugiperda in Tanzania: Possibilites and Constraints for smallholders

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Thomas O'Malley; [2024]
    Nyckelord :pheromone; mating disruption; fall armyworm; Tanzania; smallholder; Spodeptera frugiperda; integrated pest; management;

    Sammanfattning : Despite a growing interest in the use of pheromones as a more sustainable form of pest control, their use remains unstudied in the smallholder context. This paper is one of the first to study their use by small scale Tanzanian maize farmers to control the invasive pest Spodoptera frugiperda (known as fall armyworm). LÄS MER

  3. 2. Predicting Chemical-Gene Interactions

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Ali Chishti; [2023-08-04]
    Nyckelord :Pesticides; Small streams; Prediction modelling; Chemical-protein-gene interactions; Aquatic organisms;

    Sammanfattning : Pesticide use in agriculture has become a growing concern as it can have detrimental effects on the environment. The excessive use of these chemicals often leads to them seeping into nearby water bodies, causing harm to aquatic organisms. LÄS MER

  4. 3. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  5. 4. ANALYS OCH IDENTIFIERING AV BEKÄMPNINGSMEDEL I HISTORISKA TEXTILIER

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Stina Johansson; [2023-06-15]
    Nyckelord :XRF-analysis; FTIR-analysis; Pesticide Identification; Historical Textiles;

    Sammanfattning : This essay will investigate the risks associated with pesticide contamination in textile collections and how information about pesticide content can be found. Uniforms from the collection of the now closed Gothenburg military museum was analysed using Dosa test strips for chloride content, XRF-analysis and ATR-FTIR analysis. LÄS MER

  7. 5. Modelling Micropollutant Removal Through Ozonation in Wastewater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maximiliano Andrés Oportus Foster; [2023]
    Nyckelord :Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. LÄS MER
