  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. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Johansson; [2024]
    Nyckelord :Tunnel water; tunnel construction; nitrogen; fertilizer; irrigation; Länshållningsvatten; Tunnelvatten; Tunneldrivning; Kvävegödsel; Bevattning;

    Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER

  4. 3. Optimization of Solid-State Fermentation process for brown seaweed using LAB and characterization of the products

    Master-uppsats, Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

    Författare :Sweta Singh; [2024]
    Nyckelord :lactic acid bacteria; solid-state fermentation; Alaria esculenta; Saccharina latissima; seaweed fermentation; biotechnology; Technology and Engineering;

    Sammanfattning : Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. LÄS MER

  5. 4. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  7. 5. 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
