  1. 1. ENVIRONMENTAL RADIOLOGICAL STUDIES OF KVARNTORPSHÖGEN Dose and Radiological Risk Assessments for Humans and Biota

    University essay from

    Author : Felicia Hultqvist; [2021-04-06]
    Keywords : Medical physics; NORM; TENORM; Shale ash; Uranium; Polonium; Radiological risk; Humans; Biota;

    Abstract : Background: The pile Kvarntorpshögen and the lakes Surpölen and Norrtorpssjön are the remains of an industry which mined and processed oil shales to extract oil during World War II. The pile mainly consists of shale ash, a waste from the production, while the lakes are nowadays water-filled mining pits. READ MORE

  2. 2. Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Anna Stella Guðmundsdóttir; [2021-03-18]
    Keywords : ;

    Abstract : The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing FirkantenFormation, has been the subject of study for researchers in the past but little focus has been on thenortheast edge of the basin until now. Due to the economic potential of the coal seams in the formation,the Norwegian mining company, Store Norske Spitsbergen Grubekompani (SNSG), has for several yearsconducted core drilling in key locations in basin, and for decades, they have given an access to their corematerial to researchers.

  3. 3. Synthesis of Graphene - Carbon Nanotube Hybrid Structures

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Aniruddha Paul; [2021]
    Keywords : Graphene; Carbon nanotubes; Graphene-CNT hybrid structures; Chemical Vapor Deposition CVD ; Grafen; Kolnanorör; Grafen-CNT-hybridstrukturer; Kemisk ångdeposition CVD ;

    Abstract : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. READ MORE

  4. 4. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johannes Greiff; [2021]

    Abstract : The end-Triassic mass extinction (ETME) which occurred around 201 Ma is known as one of “the big five” mass extinction events of the Phanerozoic eon. Its effects were most severe on marine ecosystems, resulting in a global decline of invertebrate taxa and the complete extinction of the conodonts. READ MORE
