  1. 1. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Michelle Dossey; [2023]
    Nyckelord :PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

    Sammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER

  2. 2. Male-biased language: a diachronic corpus study of neutralization strategy in gender-based linguistic reforms

    Kandidat-uppsats, Stockholms universitet/Engelska institutionen

    Författare :Evelina Eriksson; [2023]
    Nyckelord :Corpus linguistics; generic pronouns; neutralization; linguistic reforms; epicene; gender-neutral language;

    Sammanfattning : This paper focuses on the use of English epicene pronouns in discourse which most individuals are exposed to on an everyday basis. Gender-based linguistic reforms have been implemented since the beginning of the 1970s, to achieve a more non-sexist language. LÄS MER

  3. 3. Could Tax Incidence Help Explain the Yellow Vest Movement? Evidence from France on tax incidence and heterogeneous effects of carbon and fuel taxation along the rural-urban spectrum

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Ann-Charlott Pahl; Anton Persson; [2023]
    Nyckelord :Carbon tax; Fuel tax; Tax incidence; Distributional effects; Difference-in-differences;

    Sammanfattning : There is a general consensus amongst economists that taxing carbon emissions is an efficient policy tool for combating climate change. To fully understand the thorny issues surrounding the political economy and distributional effects of carbon taxation, more attention should be paid to the rural-urban dimension. LÄS MER

  4. 4. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Giacomo Semprini Cesari; [2023]
    Nyckelord :Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Sammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER

  5. 5. Låt naturen bilda eleverna. En litteraturstudie om utomhusundervisning

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Sofia Fransson; Alma Bielsten; [2022-12-14]
    Nyckelord :Plant blindness; utomhuspedagogik; biologiundervisning; botanik; faktakunskap; didaktik;

    Sammanfattning : The aim of this literature review is to investigate if it is possible to improve students’ knowledge of plants through outdoor education in high school biology. If so, how should such education be implemented? Through database searches, articles were sorted out and compiled into a table. LÄS MER
