  1. 1. Constraining the duration of eruptions of the Rangitoto volcano, New Zealand, using paleomagnetism

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Linda Aulin; [2017]
    Nyckelord :Rangitoto; paleomagnetism; paleointensity experiments; Auckland volcanic field; thermal demagnetization; Earth and Environmental Sciences;

    Sammanfattning : The volcano Rangitoto belongs to the Auckland volcanic field and is situated north east of Auckland city, New Zealand. The volcanos of the Auckland volcanic field have previously thought to be of monogenetic origin, but recent studies indicate that Rangitoto has a long history of eruptions, which would suggest that the volcanic system may have entered a new phase.

    Sammanfattning : One of the most crucial issues nowadays is the protection of the environment and the replacement of fossil fuels, which are abundantly used around the world, with more efficient and renewable sources. The highest portion of global energy demands today is used in heating and cooling purposes. LÄS MER

  4. 3. Biomass utilization for energy purposes in Kenya : Fuel characteristics and thermochemical properties

    M1-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Natxo García López; [2016]
    Nyckelord :Bioenergy; Countries with developing economies; Wood; Agricultural residues; Thermochemical behaviour;

    Sammanfattning : About forty percent of the world´s population, mostly inhabitants of countries with developing economies, rely on the traditional usage of biomass for energy purposes. The major negative consequences are environmental and health effects. LÄS MER

  5. 4. Pyrolysis and thermogravimetric analysis of wood and its components

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Magaia Pascoa Dos Santos; [2014]
    Nyckelord :Biomass; wood; cellulose; lignin; thermogravimetric analysis;

    Sammanfattning : The present study investigates the thermochemical conversion of spruce wood and its extracted components by thermogravimetric analysis. The extracted components are two pulps, three xylan-lignin samples and one lignin sample; they were produced by the kraft cooking method with different cooking times. LÄS MER
