  1. 21. Biofunctionalization of a Fiber Optics-Based LSPR Sensor

    Master-uppsats, Linköpings universitet/Molekylär fysik

    Författare :Karl Schenström; [2016]
    Nyckelord :Localized surface plasmon resonance; LSPR; nanoparticles; AuNP; AuNR; biosensor; refractive index; spectrophotometry; IgG; insulin; avidin;

    Sammanfattning : When exposed to light, metal nanoparticles exhibit a phenomenon known as LSPR, Localized Surface Plasmon Resonance. The wavelengths at which LSPR occurs is very dependent on the refractive index of the surrounding medium. LÄS MER

  3. 22. Waste management and impact on people's health when cultivating on sites contaminated with heavy metals : Minor field study made in Zomba, Malawi

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Sofie Orvestedt; [2015]
    Nyckelord :heavy metals; contamination; waste disposal; food safety; health impact; contaminated soil;

    Sammanfattning : This minor field study was executed in Zomba, Malawi, where land for cultivation is scarce, resulting in cultivation at potentially contaminated sites. Waste dumps are one of the main sources of heavy metal contamination and excessive levels in soil might lead to elevated levels in crops which can cause severe health effects. LÄS MER

  4. 23. Deep hole drilling - Cutting forces and balance of tools

    M1-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Carmen Malave; [2015]
    Nyckelord :Deep hole drilling; resultant radial force; cutting forces.;

    Sammanfattning : Drilling is a standard process for producing holes in metal materials. With an increased hole depth the demands increase on both machine and tool. Deep hole drilling is a complex process which ischaracterized by a high metal removal rate and hole accuracy. LÄS MER

  5. 24. Plåtvändare för kvalitetssyning av plåt

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anneli Pettersson; [2014]
    Nyckelord :SSAB; Plåtvändare; Weldox; Toolox;

    Sammanfattning : This report forms the final work of the Bachelor’s degree in Product development, Blekinge Institute of Technology, spring 2014. The assignment includes the construction of a turning device for quality assurance of metal sheets’ surfaces at SSAB Oxelösund. As a model there is an already existing facility at SSAB in Mobile, USA. LÄS MER

  7. 25. Characterization of an REE-enriched black substance in fractured bedrock in the Ytterby Mine

    Magister-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Susanne Sjöberg; [2014]
    Nyckelord :;

    Sammanfattning : A black substance seeping from fractured bedrock was observed in tunnels leading to the mainshaft of the Ytterby mine on Resarö, Sweden. These are dry tunnels at shallow depth, +5 mabove sea level and 29 m below ground surface, resulting from the reconstruction of the mineinto a fuel deposit for the Swedish Armed Forces during the Cold War era.
