  1. 1. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  3. 2. 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

  4. 3. Brownification in a small stream originating from a peatland - A case study from Ryds Å in south Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Emelie Ström; Frida Karlsson Öhman; [2024]
    Nyckelord :Brownification; Peatland; Bolmen; DOM; Water Quality; Inflow; Technology and Engineering;

    Sammanfattning : Brunifiering syftar till en process där vattnet blir brunare på grund av ökade halter av naturligt organiskt material och järn, vilket innebär utmaningar för miljön och människor. Sjön Bolmen i södra Sverige har problem med brunare vatten. LÄS MER

  5. 4. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

  7. 5. Exploring the interactive effects of light intensity and pH on coral oxygen production

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Sara Wirdemark; [2023-08-07]
    Nyckelord :Ocean acidification; light intensity; photosynthesis;

    Sammanfattning : The study aimed to explore the possible interaction between acidification and light intensity and the effects on corals' oxygen production. Interactions between temperature and pH have been thoroughly researched and proven to cause immense stress on the world’s reefs. LÄS MER
