  1. 1. Fysisk aktivitet och kognitiv funktion hos personer med övervikt och obstruktiv sömnapné – en sambandsanalys

    Kandidat-uppsats, Uppsala universitet/Åsenlöf: Fysioterapi; Uppsala universitet/Åsenlöf: Fysioterapi

    Författare :Robin Larsson; Christian Skålberg; [2020]
    Nyckelord :Obstructive sleep apnea; cognitive function; physical activity; short-term memory.; Obstruktiv sömnapné; kognitiv funktion; fysisk aktivitet; korttidsminne.;

    Sammanfattning : Bakgrund: Obstruktiv sömnapné (OSA) är en sjukdom med återkommande andningsuppehåll i de övre luftvägarna till följd av delvis eller total tilltäppning av luftflödet vid sömn, vilket leder till en lägre syremättnad i blodet. Det är känt att OSA försämrar kognitiva funktioner såsom minne och inlärning. LÄS MER

  2. 2. Leaching of Glass Waste – Structure and Humidity Cell Tests

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

    Författare :Elin Sandgren; [2019]
    Nyckelord :Glass structure; glass leaching; glass modifiers; humidity cell test; saturation index; arsenic; lead.; Glasstruktur; lakning av glas; glasmodifierare; fuktkammarförsök; mättnadsindex; arsenik; bly.;

    Sammanfattning : Glass production has historically occurred at around 50 glassworks in Sweden, in a region known as the Kingdom of Crystals (Glasriket). Today, most of these sites are no longer active and left behind is glass waste of different forms (both as fragments of finished glass as well as unrefined glass melts). LÄS MER

  3. 3. Imaging the 3D distribution of cation adsorption sites in undisturbed soil

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

    Författare :Hannes Keck; [2016]
    Nyckelord :cation exchange capacity; X-ray scanning; soil structure; contrast agent; heterogeneity;

    Sammanfattning : Most soil system models assume that the cation adsorption sites in soils are accessible and homogeneously distributed in space. This assumption is likely to be invalid, which may have significant consequences on the performance of these models. LÄS MER

  4. 4. Global Sensitivity of Water Quality Modeling in the Gulf of Finland.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Daorui Lin; [2015]
    Nyckelord :Gulf of Finland; Eutrophication; Modelling; Morris sampling; Sensitivity analysis;

    Sammanfattning : The Gulf of Finland is the most eutrophied water body in the Baltic Sea, which is mainly caused by nutrient loads produced by human activities in its surrounding cities. In order to solve this environmental problem, a computational model based on the understanding the relations between eutrophication, water quality and sediments is needed to forecast the water quality variance in response to the natural and anthropogenic influences.

  5. 5. Developing an sleep scorer by using Biosignals in Matlab. : Evaluation for sleep apnea patients.

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Igor Alfredo Arroyo Porras; [2015]
    Nyckelord :Biosignals; Sleep apnea; Sleep medicine; Matlab; SHHS; AASM; polysomnography;

    Sammanfattning : Nowadays, sleep disorders e.g. sleep apnea —the cessation of airflow at the nose and mouth lasting at least 10 second— are a broadly problem around the world. Direct and indirect costs associated to sleep problems are outsize and the quality of patient life is deteriorated because of it. LÄS MER
