  1. 1. Crystallization and Emplacement of the Monte Amarelo Dikes: Magma Storage Assessment on Fogo, Cape Verde Islands

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Olle Risby; [2017]
    Nyckelord :Fogo; magma storage model; thermobarometry; clinopyroxene; intrusion landslide.; Fogo; magmalagringsdjup; termobarometri; klinopyroxen; intrusion; skred;

    Sammanfattning : The volcanic island of Fogo belongs to the Cape Verde archipelago, a two-tiered chain of islands situated 500 km west of the African coast. Fogo is regarded as one of the most active volcanoes in the world with 10 eruptions during the last 250 years. The former shield volcano Monte Amarelo reached 3500 m.a. LÄS MER

  3. 2. Biodiesel and Hydrogen Production : A Study of Nostoc sp. in Pulp and Paper Wastewater

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Duane Kimani; [2016]
    Nyckelord :Bioenergy; Hydrogen Production; Biodiesel; Cyanobacteria; Wastewater treatment;

    Sammanfattning : The modernized world is over-consuming low-cost energy sources that strongly contributes to environmental stress. As a consequence, the interest for environmentally friendly alternatives has increased immensely. One such alternative is utilizing the diazotrophic nature of the heterocystous filamentous cyanobacteria Nostoc sp. LÄS MER

  4. 3. Application of the eddy-covariance method under the canopy at a boreal forest site in central Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Vlad Pirvulescu; [2013]
    Nyckelord :closed-path system; open-path system; soil chambers; latent heat flux; carbon dioxide flux; sensible heat flux; Physical Geography and Ecosystem Analysis; eddy-covariance; Norunda; Earth and Environmental Sciences;

    Sammanfattning : The eddy-covariance (EC) method was applied at 1.5 m height, for the period 2007-2010 at Norunda, central Sweden, for calculating energy (sensible and latent heat) and carbon dioxide (CO2) fluxes. The aim of this study was to assess the applicability of EC method above the forest floor. LÄS MER

  5. 4. Measurements of electric fields in a plasma by Stark mixing induced Lyman-α radiation

    Master-uppsats, Institutionen för fysik och astronomi

    Författare :Petter Ström; [2013]
    Nyckelord :Plasma diagnostic; electric field measurement; non-intrusive; Stark effect; Lyman-alpha; hyperfine structure; H 2s ; cesium vapour;

    Sammanfattning : This paper treats a non-intrusive method of measuring electric fields in plasmas and other sensitive or hostile environments. The method is based on the use of an atomic hydrogen beam prepared in the metastable fine structure quantum state 2s1/2. LÄS MER

  7. 5. Study of driver models forside wind disturbances

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Jie Qiu; [2013]
    Nyckelord :side wind disturbance; bus stability; driver model; PID control model; preview;

    Sammanfattning : As the development of highways, it is quite normal for buses running in a speed around 100km/h. When buses are running in a high speed, they may suffer from the influence of side wind disturbances at anytime. Sometimes, it may result in traffic accidents. LÄS MER
