    Sammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER

  3. 7. Design and Construction of an Autonomous Sentry Turret Utilising Computer Vision

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Carl Bermhed; Jacob Holst; [2023]
    Nyckelord :Mechatronics; Arduino; Computer Vision; Stepper Motor; Airsoft; Haar Cascade; Mekatronik; Arduino; Datorseende; Stegmotor; Airsoft; Haar Cascade;

    Sammanfattning : The design and manufacture of a sentry gun turret capable of accurately and rapidly tracking and shooting moving targets was a challenging task that required delving into various engineering disciplines. This bachelor's thesis explores this challenge by presenting the process of construction, as well as the performance results of a turret created using a combination of 3D printing, laser cutting, and metal workshop manufacturing.

  4. 8. Identifiering av vanA och vanB hos enterokocker i bakteriepelletfrån positiva blododlingar på Genie® II Mk2 med eazyplex® VRE basic

    Kandidat-uppsats, Jönköping University/HHJ, Avdelningen för naturvetenskap och biomedicin

    Författare :Felicia Ehn; Axel Ironberg; [2023]
    Nyckelord :Loop-mediated isothermal amplification LAMP ; microbiology; molecular biology; sepsis; vancomycin-resistant enterococci VRE ; Loop-mediated isothermal amplification LAMP ; mikrobiologi; molekylärbiologi; sepsis; vankomycinresistenta enterokocker VRE ;

    Sammanfattning : En ökad utbredning av vankomycinresistenta enterokocker (VRE) har setts i Sverige sedan 2007. Bakteriemi orsakad av VRE är mycket svårbehandlad, varför snabbare tillförlitlig resistensdiagnostik är betydelsefullt för att minska dödlighet, vårdtider, vårdkostnader och belastning på sjukvårdssystemet.

  5. 9. Effekten på artsammansättning i växtsamhällen vid betning av Rangifer tarandus

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Emilie Voss-Schrader; [2023]
    Nyckelord :grazing pressure; Rangifer tarandus; species composition; vegetation analysis; Malla Strict Nature Reserve;

    Sammanfattning : The fact that large herbivores, such as Rangifer tarandus, play a part in shaping its environment through grazing and trampling of the ground is widely acknowledged today, as well as that these factors have the potential of affecting regional patterns and even global climate. This study investigated whether a considerable increase in grazing by R. LÄS MER

  7. 10. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.
