  1. 1. 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

  3. 2. 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

  4. 3. Characterization of micromotion induced by RF phase shift with photon correlation detection in a Paul trap

    University essay from KTH/Fysik

    Author : Ebba Edqvist; [2022]
    Keywords : Ion trap; Paul trap; Micromotion; Photon correlation detection; Jonfälla; Paul-fälla; Mikrorörelse; Fotonkorrelationsdetektion;

    Abstract : Trapped ions in a Paul trap can experience micromotion on top of the wanted secular motion.Micromotion can for example cause Doppler shifts in spectroscopy measurements, making it important to know the amplitude of the motion. READ MORE

  5. 4. Building a Fluorescence Correlation Spectroscopy (FCS) instrument followed bytesting the boundaries of FRET-FCS

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Isabell Weinberg-Krakowski; Evelina Stenseth; [2021]
    Keywords : ;

    Abstract : Understanding biological systems oftentimes requires mapping the behaviors of biomolecules on small scales such as single proteins or nucleic acids. Fluorescence Correlation Spectroscopy (FCS) is a group of particularly noninvasive and sensitive fluorescence-­based techniques that can be used for this purpose. READ MORE

  6. 5. Characterization andmodeling of amorphous andcrystalline ratios in poly-acrylates

    University essay from Mittuniversitetet/Avdelningen för kemiteknik

    Author : Julia Jonzon; [2020]
    Keywords : Crystallinity; Diffractogram; Microspheres; Spectra; Raman spectroscopy; XRD.;
