  1. 1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Felicia Hagberg; [2024]
    Nyckelord :PFAS; PFCA; PFSA; stormwater; guidelines; foam fractionation; activated carbon; anion exchangers; PFAS; PFCA; PFSA; dagvatten; riktvärden; åtgärder; skumfraktionering; aktivt kol; jonbytare;

    Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

  3. 2. Mining infrequent group of motifs from multidimensional time series: A case study at Alfa Laval AB

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Fabeena Thoufeeq; Reeba Susan Ashok; [2024]
    Nyckelord :;

    Sammanfattning : In collaboration with an industrial partner, Alfa Laval AB, this thesis discusses a novel approach for identifying operational modes, specifically a cleaning mode, in separator machines without the benefit of labelled data and with very limited operating knowledge. Understanding the operational modes is crucial for comprehending the machine’s behaviour and ensuring its optimal performance. LÄS MER

  4. 3. Tillit, misstro och motstånd : En studie av skolutvecklingsaktörers konstruktioner av skolutvecklingens villkor

    Magister-uppsats, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Maria Jakobsson; [2023]
    Nyckelord :instructional; governance and management; school leader; school development; trust; mistrust; undervisnings-; styrning och ledning; skolledare; skolutveckling; tillit; misstro;

    Sammanfattning : The purpose of this study is to uncover and problematize how school management and senior teachers perceive governing and management of school development processes from a perspective of trust. The research questions are the following: “Which constructs of trust emerge among school management and senior teachers in governing and management of school development processes?” and “Which constructs of possibilities and challenges emerge among school management and senior teachers in governing and management of school development processes from a perspective of trust?” The study has a social constructivist design where a framework for evaluation of trust versus mistrust (the Trust/Mistrust matrix: TDM) was used in the analysis.

  5. 4. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Oskar Sundberg; [2023]
    Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

    Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER

  7. 5. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood

    Master-uppsats, KTH/Fiber- och polymerteknologi
