  1. 1. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

    Master-uppsats, Stockholms universitet/Institutionen för miljövetenskap

    Författare :Viktor Munkhammar; [2023]
    Nyckelord :Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

    Sammanfattning : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. LÄS MER

  3. 2. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Emma Eriksson; [2023]
    Nyckelord :Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Sammanfattning : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

  4. 3. Trainable Region of Interest Prediction: Hard Attention Framework for Hardware-Efficient Event-Based Computer Vision Neural Networks on Neuromorphic Processors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Cina Arjmand; [2023]
    Nyckelord :Artifical Intelligence; Machine Learning; Neuromorphic Engineering; Computer Vision; Technology and Engineering;

    Sammanfattning : Neuromorphic processors are a promising new type of hardware for optimizing neural network computation using biologically-inspired principles. They can effectively leverage information sparsity such as in images from event-based cameras, and are well-adapted to processing event-based data in an energy-efficient fashion. LÄS MER

  5. 4. The Examination of Alternative Methods for Sperm Cell Lysis and Purification of Sexual Assault Samples

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Emilie Boson; [2023]
    Nyckelord :Differential lysis; Differential extraction; Sexual assault samples; Sperm cells; Forensic; DNA recovery; DNA profiling; DNA purification; Applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. LÄS MER

  7. 5. Droganvändning bland barn och unga : Orsaker till barn och ungas droganvändning

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Jawid Hashemi; [2022]
    Nyckelord :Barn; biomedicinska modellen; droganvändning; litteraturstudie; orsaker; sociologiska inlärningsteorier; ungdomar.;

    Sammanfattning : The purpose of this survey was to examine motives for adolescents' drug use. This study is a scoping study based on peer-reviewed, scientific articles. The data was collected by using diverse word combinations, filters and search words in different databases to find relevant articles to answer the question formulations. LÄS MER
