  1. 1. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Moa Sjöberg; [2023]
    Nyckelord :PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

    Sammanfattning : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. LÄS MER

  3. 2. Developing an Automated System for Yeast Culture Cultivation and Control using Flow Cytometry

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Sara Magnusson; [2023]
    Nyckelord :Yeast; flow cytometry; applied microbiology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Flow cytometry is a versatile tool for monitoring a microbial population at a single-cell level. Multiple parameters can be monitored based on the users’ requirements through the utilization of different dyes, biosensors etc. LÄS MER

  4. 3. Carbon Flows in Sweden : A Substance Flow Analysis of anthropogenic carbon flows

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sofia Gunnarsson; [2022]
    Nyckelord :Carbon; Carbon Flow; Carbon Stock; Substance Flow Analysis; Sweden; Industrial Ecology; Anthropogenic;

    Sammanfattning : Carbon (C) is an essential element for all life. However, modern livestock keeping and usage of carbon through burning of fossil fuels are resulting in increased concentrations of carbon dioxide and methane in the atmosphere, two important greenhouse gases (GHG). LÄS MER

  5. 4. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  7. 5. Översilningsytors potential att rena lakvatten från PFAS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emma Larsson; [2020]
    Nyckelord :PFAS; leachate; overland flow area; waste facility; waste; landfill; PFAS; lakvatten; översilningsytor; avfallsanläggning; avfall; deponi;

    Sammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER
