  1. 1. Hydrological catchment analysis from characterisation of organic matter in stream water

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Hannes Berg Wiklund; [2020-02-05]
    Nyckelord :Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

    Sammanfattning : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed duringthe last decade due to the introduction of high resolution mass spectrometers. The compositionof OM in the aquatic environment is directly dependent on factors such as oxygen supply, pHand the flow rate in the local system. LÄS MER

  3. 2. The Principles of a Stable Community : 90 Years of Structured Integration in a Culturally Diverse New Town in Sardinia

    Master-uppsats, Uppsala universitet/Institutionen för kulturantropologi och etnologi

    Nyckelord :new town; community spirit; design; town planning; community; structuration theory; productivity; Arborea; Sardinia; Italy;

    Sammanfattning : An atom, a cell and a solar system have very little in common. My science teachers from high school will confirm that I am very far from being an expert on the matter but nontheless, I have studied these three systems in separate classes: chemistry, biology and astronomy.

    Sammanfattning : Den här undersökningen har sitt fokus på förskolans yngsta barn, 1 – 2,5 år, och deras kommunikation i relation till fasomvandlingen från fast form till flytande form. Syftet med undersökningen är att belysa hur förskolans yngsta barn kommunicerar om naturvetenskapliga fenomen. LÄS MER

  7. 5. Verification of hypochromic erythrocytes on Sysmex XN 2000

    L3-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Dakakni Aghyad; [2020]
    Nyckelord :Anemia diagnosis and management; Calculation of Erythrocyte Parameters; Functional iron deficiency; Hemoglobin; Hematology analyzer.;

    Sammanfattning : Anemia is a serious blood disease that more than two billion suffer from worldwide. Half of that number consist of iron deficiency anemia, which is insufficiency of iron supply to the bone marrow due to empty iron store or hampered iron utilization due to inflammation. Therefore, requires rapid diagnosis. LÄS MER
