  1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elias Önerud; [2023]
    Keywords : Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Abstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

  3. 2. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Paul Böhm; [2023]
    Keywords : re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

    Abstract : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.

  4. 3. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

  5. 4. Nitridation of Lithium Silicate Phosphate Glasses for Application as Solid Electrolyte : A Material Properties Study

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Freddy Tönnesen; [2023]
    Keywords : Lithium-silicate-phosphate; glasses; batteries; electrical conductivity; nitridation behavior; oxynitride glasses;

    Abstract : The pursuit of sustainable and high-performance materials is of utmost significance in driving the progress of battery technologies. Solid-state technology represents a promising avenue for the development of batteries with improved sustainability and performance. READ MORE

  6. 5. Co-evolutional anaylsis of the Na+,K+-ATPase’s β-subunit dimerization

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Bauer; [2023]
    Keywords : Na ; K -ATPase NKA ; Co-evolution; Dimerization; Direct coupling analysis DCA ; Molecular dynamic MD simulation; Contact filtering; Mapping; Na ; K -ATPas NKA ; Samevolution; Dimerisering; Direkt kopplingsanalys DKA ; Molekylär dynamisk MD simulering; Kontaktfiltrering; Kartläggning;

    Abstract : Does the active membrane transporter, Na+,K+-ATPase dimerize? If it does, whatis the functional benefit? Does it increase or decrease the turnover rate? Theseare still unanswered questions and current research topics. Previous studies havedemonstrated dimerizations in closely related proteins of the P-type ATPase family. READ MORE
