  1. 1. Gjutning av rostfritt stål med 3D-printade sandformar

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Olle Lindqvist; Gustaf Thulin; [2020]
    Nyckelord :3D-printing; additiv manufacturing; casting; construction; stainless steel; sand mold; 3D-printning; additiv tillverkning; gjutning; konstruktion; rostfritt stål; sandform;

    Sammanfattning : Sand mold casting is a manufacturing method that has been used for thousands of years. In recent years additive manufacturing has, among other things, enabled production of sand molds with complex geometry resulting in castings with geometry that would have been very hard, if not impossible, to produce with conventional sand mold casting or machining procedures.

  3. 2. Anestesisjuksköterskors upplevelser i samband med organuttagsoperationer från avlidna donatorer

    Magister-uppsats, Linnéuniversitetet/Institutionen för hälso- och vårdvetenskap (HV)

    Författare :Olle Sand; [2016]
    Nyckelord :anestesisjuksköterska; upplevelser; organdonation; avliden donator; organuttagsoperation;

    Sammanfattning : Bakgrund: I Sverige väntar för närvarande ca 800 personer på att få transplanteras med ett, eller flera organ. För dessa svårt sjuka människor är organtransplantation sista utvägen. En organdonation är en ovanlig företeelse och det behövs mer kunskap om olika aspekter av omvårdnad vid organdonation. LÄS MER

  4. 3. Evaluation of bokashi fermentation leachate as a biofertilizer in urban horticulture : inorganic plant nutrient content in bokashi leachate and its effect as a fertilizer on pak choi

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Olle Lind; [2014]
    Nyckelord :biofertilizer; bokashi leachate; EM; pak choi; urban horticulture;

    Sammanfattning : The leachate obtained from bokashi fermentation household vessels, are among proponents of the bokashi method believed to be useful as a biofertilizer. The bokashi fermentation method does not lead to foul odours as it is anaerobically fermented in air-­tight bins with lactic acid bacteria, among other groups of microorganisms, and is therefore interesting in the light of an increasing interest of urban farming and unexploited resources of plant mineral nutrients within the urban area.

  5. 4. Effects of the adaptive background in the spectral sensitivity of budgerigars (Melopsittacus undulatus)

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Johanna Chávez; [2012]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : ABSTRACT The objective of this project was to study if the adaptive background affects the spectral sensitivity of budgerigars (Melopsittacus undulatus) tested in bright light. Two budgerigars were trained, by associative learning with food rewards, in dual choice tests to discriminate monochromatic light stimuli of nine different wavelengths from an adaptive background with ultraviolet light (UV) content.
