  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  3. 2. Circularity through Collaboration - A Case Study on Textile Industry

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Balajishnu Udayakumar; Marcello Benincasa; [2024]
    Nyckelord :Circular economy; Collaboration; CE strategies; System perspective; Textile industry;

    Sammanfattning : In the last decade, circular economy (CE) has gained widespread attention among scholars, practitioners, and policymakers as a sustainable alternative to the current linear system. This system, which operates under the logic of "take-make-dispose", poses significant threats to our environment due to the exponential growth in natural resource extraction that we have witnessed in the last fifty years.

  4. 3. Ecological Fashion Perspectives of the Green Generation: Examining Gen Z and Millennial attitudes towards the Swedish fashion industry's efforts to reduce emissions of greenhouse gases

    Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Amanda Håkansson; [2023-10-18]
    Nyckelord :sustainable development; fashion industry; environmental discourses; greenhouse gas emissions; attitudes;

    Sammanfattning : This paper seeks to examine how young Swedish consumers appurtenant to Generation Z and the Millennial generation perceive the effort made by four leading Swedish fashion companies H&M, Lindex, Kappahl, and Gina Tricot to reduce their emissions of greenhouse gases. Further, it explores the general attitudes that these generations hold toward the Swedish Fashion Industry’s approach to sustainable dev elopment. LÄS MER

  5. 4. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ivan Krsic; [2023]
    Nyckelord :HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Sammanfattning : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. LÄS MER

  7. 5. Patienters upplevelser av bemötande hos fysioterapeut vid långvarig ländryggssmärta : en kvalitativ intervjustudie

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Edvin Abramsson; [2023]
    Nyckelord :Bemötande; Delaktighet; Fysioterapi; Kommunikation; Ländryggssmärta;

    Sammanfattning : Bakgrund: Långvarig ländryggssmärta är den vanligaste orsaken till funktionsnedsättning hos människor i åldrarna 45–65 år. Orsaken till långvarig ländryggssmärta varierar men individuella faktorer som ålder, fysisk aktivitet samt psykologiska faktorer som ångest, stress och depression kan vara faktorer som kan bidra till besvären.
