  1. 1. Composition methods related to chemistry and biology

    Master-uppsats, Göteborgs universitet/Högskolan för scen och musik

    Författare :Óscar Calatayud-Gómez; [2020-06-17]
    Nyckelord :Music composition; composition methods; biology; chemistry; Crystallization; DNA; Brain Activity;

    Sammanfattning : This master thesis presents three different methods of composing music with someprocesses, concepts and models from the fields of chemistry and biology, in which I haveresearched theoretically and practically in order to obtain and to generate the musicalknowledge for this work.Historically, one of the ways of obtaining and creating musical material and musicalnetworks has been the connection of music with other fields, such as literature, sculptureor maths.

  3. 2. Complex REE zonations in metamorphic garnet reflect accessory mineral reactions

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Niclas Hultin; [2020-05-29]
    Nyckelord :Rare Earth Elements; REEs; Garnet; LA-ICP-MS; Sesia zone; Metamorphism;

    Sammanfattning : A garnet from the Sesia Zone, NW Italy, was selected for Major and Rare Earth Element(REE) mapping, using LA-ICP-MS – a procedure previously not conducted at the Departmentof Earth Science at University of Gothenburg. The original inclusion assemblage of the garnetis preserved, and the mapping revealed two distinct changes in both garnet chemistry andinclusion assemblage, both which can be linked to the metamorphic development of theregion.

  4. 3. 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

  5. 4. Animationer i kemiundervisningen : Ett vägledande material för användning av animationeri kemiundervisningen i gymnasieskolan

    Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande; KTH/Lärande

    Författare :Matthias Hultin; Emma Perhult; [2020]
    Nyckelord :animations; chemistry education; learning; didactics; prior knowledge; animationer; kemiundervisning; lärande; didaktik; förkunskaper;

    Sammanfattning : Syftet med detta examensarbete var att undersöka animationer i kemiundervisning på gymnasieskolan. Mer specifikt: att utreda hur animationer för närvarande används i undervisningen, vilken betydelse förkunskaper har på elevens förståelse av animationer och även hur förståelsen påverkas av animationens design.

  7. 5. Archaeologic inspection of the Milky Way using vibrations of a fossil : Seismic, spectroscopic and kinematic characterization of a binary metal-poor Halo star

    Kandidat-uppsats, Uppsala universitet/Observationell astrofysik

    Författare :Amanda Byström; [2020]
    Nyckelord :Milky Way; Halo; galactic archaeology; asteroseismology; binary star; CEMP stars; CEMP-r s stars; stellar age; stellar mass; chemical abundance pattern; Gaia-Enceladus; Gaia-Sausage; Sequoia; spectroscopy; metal-poor;

    Sammanfattning : The Milky Way has undergone several mergers with other galaxies during its lifetime. The mergers have been identified via stellar debris in the Halo of the Milky Way. The practice of mapping these mergers is called galactic archaeology. To perform this archaeologic inspection, three stellar features must be mapped: chemistry, kinematics and age. LÄS MER
