  1. 1. Measuring bacterial metabolism and antibioticsusceptibility : using silicon nanowire field-effect transistor.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :George Alhoush; [2024]
    Nyckelord :Silicon nanowire field effective transistor; SiNWFET; Ion-selective filed effect transistor; ISFET; Antibiotic susceptibility test; AST; Measuring bacterial metabolism using microchip;

    Sammanfattning : Antimicrobial resistance is considered by many prominent researcher and scientist as a profound global health crisis that us humans must face in the next decade. It is threatening the effectiveness of these once-reliable weapons against bacterial infections and leaving us susceptible to pathogenic agents. LÄS MER

  3. 2. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

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

    Författare :Alexina Brännlund; [2023]
    Nyckelord :Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Sammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  4. 3. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Margot Jeanne Knapen; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; LPJ-GUESS; Arctic; FLUXNET; Gross Primary Productivity; Ecosystem Respiration; Permafrost; Active Layer Thickness; Snow Depth; Earth and Environmental Sciences;

    Sammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER

  5. 4. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Franklin Lee Harris; [2023]
    Nyckelord :microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

    Sammanfattning : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. LÄS MER

  7. 5. 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
