  1. 1. Kartläggning av lustgasens användning vid smärtsamma procedurer på barn på akutmottagning.

    Magister-uppsats,

    Författare :Sara Franzon; Josefin Grefve; [2021-04-23]
    Nyckelord :Akutmottagning; Barn; Lustgas; N2O; Smärtsamma procedurer;

    Sammanfattning : Background: Children often experience pain and fear with painful procedures in healthcare. Previous research shows that undertreated pain during procedures is a problem and can have negative consequences in the future for children. A suitable treatment is nitrous oxide, which has both a pain-relieving and a sedative effect. LÄS MER

  2. 2. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Passad; [2021]
    Nyckelord :Physics; Optics; Lasers; Environment; Hydrogen; Hydrogen Energy; Ammonia Energy; DFWM; Ammonia; Nitrous Oxide; Ammonia Flame; Ammonia Combustion; Physics and Astronomy;

    Sammanfattning : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. LÄS MER

  3. 3. Återvätning av organogen jordbruksmark: Möjligheter för klimatvinster i Lunds kommun

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Emma Brodén; [2020]
    Nyckelord :cultivated organic soils; rewetting; greenhouse gas emissions; City of Lund; Earth and Environmental Sciences;

    Sammanfattning : Drained organic soils are a big source of greenhouse gas (GHG) emissions. Many of these soils have, historically, been drained to increase the share of agricultural land. In Sweden, they emit around 3.4 million tonnes CO2 and 0. LÄS MER

  4. 4. Markytesänkning, växthusgasavgång och utlakning från dikad torvjord

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Författare :Martin Ahlvin; Sofia Alexandersson Ros; [2020]
    Nyckelord :Dikad torvmark; höjdmätning; markytesänkning; koppargödsling; växthusgaser;

    Sammanfattning : Greenhouse gas emissions and land subsidence on four cultivated peat soils (Martebo, Örke, Kälkestad, Lidhult) have been investigated by measuring emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) in field and lab. Greenhouse emitted gas (mg/h) from undisturbed soil cores was measured in lab. LÄS MER

  5. 5. En våt klimatåtgärd - möjligheter och konflikter med återvätning av dikade skogbeklädda torvmarker för att minska klimatpåverkan

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Marika Olsson; [2020]
    Nyckelord :rewetting; peatland; forestry; climate mitigation; greenhouse gases; Earth and Environmental Sciences;

    Sammanfattning : Peatlands store substantial amounts of carbon. When drainage of these areas occurs in order to use for practices such as forestry, greenhouse gases (GHG) will be emitted which will enhance climate change. LÄS MER
