  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  3. 2. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  4. 3. Kvillebäcken : analys och gestaltningsförslag - me[d]andra strukturer och processer

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Louise Stigsson Rigné; Emil Vernersson; [2024]
    Nyckelord :Urbanekologi; landskapsarkitektur; hydrologi; vattendrag; naturbaserade lösningar; blågrön infrastruktur;

    Sammanfattning : I byggandet av hållbara städer är utveckling av blågrön infrastruktur högaktuell, och inom detta faller stort fokus på utveckling av urbana vattendrags ekologi, vattenkvalitet, och förmåga att omhänderta konsekvenser av klimatförändringar. Få vattendrag uppnår miljökvalitetsnormerna, och platsspecifika utmaningar finns i varje vattendrag. LÄS MER

  5. 4. FRÅN VITT TILL GRÖNT, RÖTT ELLER BRUNT: Kan blindering åtgärdas med kunskap vi redan har?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Annica Drotz; [2023-11-07]
    Nyckelord :blanching; oil paint; bloom; paint layer; accelerated aging; consolidation;

    Sammanfattning : Blanching is a common phenomenon affecting the binding medium within the paint, resulting in an abnormality of the paints light scattering. Multiple studies have confirmed that the change is the result of pore formation within the binding medium caused by humidity or water damage. 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
