  1. 1. Patienters upplevelse av hjärtinfarkt i det akuta skedet : En beskrivande litteraturstudie

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Avdelningen för vårdvetenskap

    Författare :Lukas Andersson; Linnéa Lilja; [2024]
    Nyckelord :Acute; myocardial infarction; patients experience; Akut; hjärtinfarkt; patienters upplevelse;

    Sammanfattning : Bakgrund. I Sverige år 2022 drabbades cirka 23 200 människor av hjärtinfarkt och cirka 4 700 personer avled. Risken för att drabbas ökar i samband med dålig livsstil. LÄS MER

  3. 2. 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

  4. 3. Designing a reactive feedback feature for end-users in web-based media software

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Jessica Dellmar; [2024]
    Nyckelord :User Feedback; End-user involvement; Usability; Design Thinking; User Experience;

    Sammanfattning : Customer feedback is essential for improving a company's products or services and increasing customer satisfaction. Despite its value, user involvement faces many challenges, such as low user motivation and feedback with missing context information. LÄS MER

  5. 4. 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.

  7. 5. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

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

    Författare :Carl Pontén; [2024]
    Nyckelord :Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

    Sammanfattning : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.
