  1. 6. Sustainable food packaging based on polyhydroxyalkanoate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Safana Al-Ashor; [2024]
    Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

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

    University essay from Lunds universitet/Matematik LTH

    Author : Sally Vizins; Hanna Råhnängen; [2024]
    Keywords : 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;

    Abstract : 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. 8. Beständigheten hos brandimpregnerat trä

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Filip Engström; Hannes Psajd; [2024]
    Keywords : Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Abstract : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  5. 9. Prospects for standardisation of industrial PET plastics to support the transition towards a circular economy

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Agnes Ström; [2024]
    Keywords : Standard; standardisation; industrial PET; polyethylene terephthalate; circular economy; plastic; Technology and Engineering;

    Abstract : Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser.

  6. 10. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ellen Svens; [2024]
    Keywords : Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

    Abstract : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.
