1. 11. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

   Master-uppsats, Uppsala universitet/Geofysik

   Författare :Wanyi Li; [2022]
   Nyckelord :Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

   Sammanfattning : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. LÄS MER

3. 12. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Författare :Viktor Sparrman; [2022]
   Nyckelord :Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

   Sammanfattning : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. LÄS MER

4. 13. Quantum Landau-Lifshitz-Gilbert Dynamics of a Dimer

   Master-uppsats, Uppsala universitet/Teoretisk fysik; Uppsala universitet/Materialteori

   Författare :Lee Johnson; [2022]
   Nyckelord :;

   Sammanfattning : The classical Landau-Lifshitz-Gilbert (LLG) equations are of crucialimportance in micro-magnetism, but a true quantum-mechanical descriptionwas not found until 2013. However, very few realistic quantumsystems have been modeled using it. LÄS MER

5. 14. Late Quaternary Climate Reconstruction Using Rock - Magnetism in Loess on Portelet, Jersey

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Elias Hero; [2022]
   Nyckelord :;

   Sammanfattning : Loess is a very fine aeolian sediment that can be used as a proxy for stadial and interstadial glacialperiods. To understand how Earth’s climate have changed and what effects that change have had on theplanet and life on it we can use climate archives. LÄS MER

7. 15. Pedagogers uppfattningar om fysikundervisning i förskolan : En enkätstudie om hur pedagoger i en medelstor kommun i Mellansverige undervisar i ämnet fysik

   Uppsats för yrkesexamina på grundnivå, Karlstads universitet

   Författare :Emelie Amcoff; Valdete Sejdiu Seferi; [2022]
   Nyckelord :Physic education in preschool; physics in the preschool curriculum; physical phenomena; prerequisites for physics education; the competence of educators.; Fysikundervisning i förskolan; fysik i förskolans läroplan; fysikaliska fenomen; förutsättningar för fysikundervisning; pedagogers kompetens;

   Sammanfattning : The purpose of this study is to investigate how educators in preschool view teaching physics and how it is carried out together with the children. To find out about this, the study has been conducted with help of digital questionnaires where all educators in a medium-sized municipality in central Sweden have been given the opportunity to answer.
