  1. 16. När det positiva leder till något negativt

    Magister-uppsats,

    Författare :Emelie Michael; Sara Nilsson; [2022-04-21]
    Nyckelord :Bukläge; komplikationer; invasiv ventilatorvård; intensivvård; riskfaktorer;

    Sammanfattning : Bakgrund: Bukläge har använts som en behandlingsintervention inom intensivvården sedan 1970 men fått ökad genomslagskraft under Covid-19 pandemin. Det kan användas vid respiratorisk svikt oavsett genes för att förbättra gasutbytet och öka syresättningen samt har även påvisat en minskad mortalitet hos patienter med respiratorisk svikt. LÄS MER

  3. 17. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Melina Al Nasser; Linn Gromert; [2022]
    Nyckelord :Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Sammanfattning : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. LÄS MER

  4. 18. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

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

    Författare :Sophia Leffler; [2022]
    Nyckelord :spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

    Sammanfattning : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. LÄS MER

  5. 19. Avian Malaria infection and its effect on cellular metabolic rate in Ficedula Flycatchers

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Författare :Nader Ibrahim; [2022]
    Nyckelord :;

    Sammanfattning : Chronic avian malaria and low-intensity parasite infections can have a negative influence on reproduction and survival which can reduce the fitness of the host. Therefore, the effect on host due to avian malaria infection can affect a bird’s lifespan. Consequently, avian parasites can influence evolution, physiology, and host morphology. LÄS MER

  7. 20. Controls of the partitioning of nitrate between DNRA and denitrifiers

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Frida Lindvall; [2022]
    Nyckelord :DNRA; denitrification; microcosm; experiment; arable soil;

    Sammanfattning : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. LÄS MER
