  1. 21. Exploring feedstock supply chain for large scale manufacturing of recycled cellulosic textile fiber : A collaborative business model analysis

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :SM Toufiqur Rahman; [2022]
    Nyckelord :Post-industrial textile waste; Textile Upcycling; Supply Chain Management; Collaborative Business Model; Feedstock sourcing; Sourcing; recycled cellulosic pulp; large scale textile recycling; chemical recycling of textiles.;

    Sammanfattning : The textile industry is considered one of the most challenging industries when it comes to environmental pollution just after the oil industry. It has a huge impact on water pollution and resource consumption in terms of fiber production. LÄS MER

  3. 22. Novel Scale Chemistry of Salmo Salar L. : New Linkage of Otolith and Scale Chemistry to M74 Reproductive Disorder

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Michelle Von Ehr; [2022]
    Nyckelord :Thiamine; M74; Salmon; Otolith chemistry; Scale chemistry; laser-ablation coupled inductively plasma mass spectrometry;

    Sammanfattning : Baltic salmon suffer from maternally transmitted M74 reproductive disorder, which causes yolk-sac fry mortality due to thiamine deficiency. This study investigates trace elemental analyses of Baltic salmon applied on otoliths and scales and their possible link to identifying M74. LÄS MER

  4. 23. Miljö- och förvaltningsrättsligabestämmelser - Effektiva tillsammans? : I ljuset av den kommunala operativa miljötillsynen över enskilda (små) avlopp

    Magister-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Josefin Sundin; [2022]
    Nyckelord :Miljörätt; Förvaltningsrätt; enskilda avlopp; operativ tillsyn; kommunal tillsyn; ramvattendirektivet; miljöbalken;

    Sammanfattning : Water is one of our most important natural resources and access to clean water is a matter forboth current and future generations. During the past decades, overexploitation, pollution, andclimate change has led to serious consequences in the water section around the world. LÄS MER

  5. 24. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Nanna Walther; [2022]
    Nyckelord :Environmental toxicology; Symbiodiniaceae; miljötoxikologi; phytoplankton; UV-filter chemicals; corals; environmental biology; biology; toxicology; chemicals; sunscreen; pollution; ocean; coral bleaching;

    Sammanfattning : Coral bleaching causes the disappearance of unique ecosystems supporting thousands of different species. The corals health depends on its relationship with its endosymbiont, the zooxanthellate Symbiodiniaceae. This mutualistic relationship can be disrupted by anthropogenic chemical pollution by inducing physiologically stress in Symbiodiniaceae. LÄS MER

  7. 25. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Freja Hansson; [2021]
    Nyckelord :Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

    Sammanfattning : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. LÄS MER
