  1. 1. Behind grades: Extramural, environmental and individual factors in learning English as a foreign language

    Magister-uppsats, Stockholms universitet/Engelska institutionen

    Författare :Amanda Milla Moilanen; [2024]
    Nyckelord :English as a Foreign Language; EFL; Extramural English; Environmental Factors; Individual Differences;

    Sammanfattning : The EF English Proficiency Index has presented high English proficiency levels for Swedish students. Previous investigations have studied different factors that contribute to high proficiency in a second language, such as the engagement with the language in the free time, or personal characteristics such as motivation or learners’ home environment.

  3. 2. The mirage of agreeableness : A study of the impact of free-riding behavior on the sucker-effect

    Kandidat-uppsats, Södertörns högskola/Psykologi

    Författare :Adnan Suljakovic; Gustav Westerman; [2024]
    Nyckelord :Sucker-effect; free-rider; social loafing; agreeableness; group work; in-group; out-group; dyads; motivational loss;

    Sammanfattning : In group work, the sucker-effect is a motivational loss in which effort is reduced due to feeling taken advantage of when other group members intentionally avoid work, known as free-riding. No previous studies on the sucker-effect have investigated moderating factors that can be attributed to the free-rider. LÄS MER

  4. 3. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

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

    Författare :Máté Károly Tóth; [2023]
    Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

  5. 4. Microfluidic flow splitter shape optimization for high throughput

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Nyckelord :Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Sammanfattning : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. LÄS MER

  7. 5. Analysis of fatty acids in fatty acid-based herbicides by gas chromatography

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mohamad Abd Elwadood; [2023]
    Nyckelord :Analytical Chemistry; Fatty Acids; Gas Chromatography; Green Herbicides; Retention Index; Flame Ionization Detector; Mass Spectrometry; Supercritical Carbon Dioxide Extraction.; Chemistry;

    Sammanfattning : Fatty acids-based herbicides are considered to be a green alternative to synthesized weed control products. However, the environmentally sustainable effect of those herbicides needs more investigation to be confirmed. LÄS MER
