  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

  2. 2. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    Master-uppsats, KTH/Fysik

    Författare :Dennis Åkerström; [2024]
    Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Sammanfattning : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. LÄS MER

  3. 3. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

    Författare :Johan Holmberg; [2024]
    Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  4. 4. ATTRAHERA OCH BEHÅLLA REKRYTERARE - En kvantitativ undersökning inom rekryteringsbranschen om vad medarbetare uppskattar hos arbetsgivare

    Kandidat-uppsats, Göteborgs universitet / / Institutionen för sociologi och arbetsvetenskap

    Författare :Johanna Kalered Martinsson; Thyra Svensson; [2023-09-13]
    Nyckelord :Employer Branding; Employer Value Propositions; Generations; Human Resource Management; Talent Attraction;

    Sammanfattning : This study aims to investigate which employer value propositions, EVPs, are valued most highly by employees in the recruitment industry. The study's purpose is further extended to examine whether generational differences can be observed in the evaluation of EVPs. A quantitative approach with a questionnaire survey was used. LÄS MER

  5. 5. Hur använder man x egentligen?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Agnes Wallgren; [2023-04-19]
    Nyckelord :Bokstavssymboler; Algebra; Variabler; Elever; Matematik; Uppfattningar; Svårigheter; Missuppfattningar; Elevförståelse.;

    Sammanfattning : The purpose of this thesis was to investigate whether students understanding of letter symbols in algebra has changed since Dietmar Küchemanns study in 1976, as well as to see whether teachers’ view on students understanding and their misconceptions correlate with the test results shown by the students. To be able to measure the students understanding, the same test that Küchemann used in 1976 was used on students aged 15/16 today (although on a much smaller scale), and the results were then analysed, and the students were categorised into different levels of understanding, based on the descriptions of the levels made by Küchemann in 1981.
