  1. 16. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    University essay from Uppsala universitet/Naturresurser och hållbar utveckling

    Author : Joanna Ghaderidosst; [2020]
    Keywords : Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Abstract : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. READ MORE

  3. 17. Transcriptomic analysis on freshwater mussels for identification of potential biomarkers to monitor water ecosystems

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Md Mehedi Hasan Joyon; [2020]
    Keywords : ;

    Abstract : Stress-specific expression of cellular proteins in responses to exogenous exposure and resulting physiological alteration provides important insight into the field of ecological research. Due to its habitat, feeding, lifestyle and physiologic properties, mussel has become an important indicative measure of aquatic environment pollution in order to assess effect of these pollution in aquatic life.

    Keywords : chitin; chitosan; fibers; nanofibers; textiles; wound dressing; sutures; spinning;

    Abstract : Ökningen av världspopulationen har orsakat en ökad avfallsgenerering. Avfallet kan innehålla betydelsefulla ämnen, vilka kan användas som råvaror i många olika material och för olika ändamål. READ MORE

  5. 19. Indoor Air Pollution, Passive Ventilation Strategies and Thermal Comfort in Nepal

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marianne Löwgren; [2019]
    Keywords : Energy poverty; Solid biomass fuels; Improved cooking stoves; Indoor air pollution; Carbon monoxide; Vernacular architecture; Passive ventilation; Air exchange rate; Indoor air quality; Thermal comfort; Operative temperature; Sustainable societal development; Social Sciences; Technology and Engineering;

    Abstract : Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. READ MORE

  6. 20. Material identification using X-ray diffraction

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Linda Genetu Teggen; [2019]
    Keywords : XRD; XRF; incineration; wastemanagement; toxic elements; pollution detection; fly ash; ash; Bruker D2Phaser; DIFFRAC.EVA; chemical filter; scan file.;

    Abstract : This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. READ MORE
