  1. 1. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  3. 2. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Aubree Stephens; [2023]
    Keywords : methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

    Abstract : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. READ MORE

  4. 3. Skadebild och fördelning av törskate på träd- och beståndsnivå hos tallungskog

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Moa Kinnunen; Björn Jönsson; [2022]
    Keywords : Törskate; Törskaterost; Svampskador; Rostsvamp; Multiskadad ungskog; Skadebild av törskate; Cronartium pini; Cronartium flaccidum; Peridermum pini; Resin-top disease; Rust fungi; Scots pine bister rust; Two-needle pine stem rust; Pine rust;

    Abstract : Törskate är ett alltmer uppmärksammat problem i framförallt Sveriges norra delar, där 12 till 15 % av de naturliga avgångarna av tall anses orsakade av svampen. Detta motsvarar en produktionsförlust på ca 350 000 kubikmeter talltimmer årligen. READ MORE

  5. 4. Geometry studies of high energy 16O collisions

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Aliaksei Kuzmenka; [2022]
    Keywords : Ion Collisions; Oxygen; Physics and Astronomy;

    Abstract : In this project a model of oxygen, 16O, nuclei, where the nucleons are organised in α-clusters, was implemented in the Pythia Monte Carlo event generator. To study the effects of the new model, some observables, such as the distribution of the number of the wounded nucleons, charged particle multiplicity in the forward and central pseudorapidity region, and the pseudorapidity distribution for different centrality bins and eccentricity, are compared to the model originally implemented in Pythia (Woods-Saxon).

  6. 5. Exploring the factors affecting just sustainability transitions in the agri-food sector in developing countries : The case of Peruvian blueberries

    University essay from Uppsala universitet/Industriell teknik

    Author : Cesar La Torre Ramirez; [2021]
    Keywords : Sustainability Transitions; Agri-food system; developing country; blueberries;

    Abstract : The agri-food sector is responsible for 26% of the total global carbon emissions. This puts the sector under the critical eye of the world, which demands radical solutions to this. For this, alternatives to unsustainable practices have already been implemented and have led to the transformation of the systems into more sustainable ones. READ MORE
