  1. 1. Vedlevande skalbaggar 10–20 år efter brand i tallskog : en jämförelse mellan hällmark och produktiv mark

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : KajsaLisa Olsson; [2024]
    Keywords : Tallimpediment; biologisk mångfald; vedlevande skalbaggar; naturvårdsbränning; Pinus sylvestris;

    Abstract : The Swedish boreal forests have changed drastically in the last century. Intensive forestry with clear-cuttings and fire-prevention, cause a lack in dead wood diversity and volume. The current research on forests mainly focuses on productive forests and there is a knowledge gap regarding the importance of low-productive forest for biodiversity. READ MORE

  3. 2. N-body simulations of exoplanets and their moons

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

    Author : Lydia Schollmeier; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. READ MORE

  4. 3. Development and testing of a novel solar dryer design with an incorporated heat exchanger - For use in the Himalayan regions

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Adam Probert; [2022]
    Keywords : Technology and Engineering;

    Abstract : Food scarcity is a common occurrence for farmers in the rural Himalayan regions. As fruits and vegetables are a crucial part of most farmers' diet, food deficiency can become evident in between harvesting periods, when there is no fresh supply. READ MORE

  5. 4. Diversity patterns and composition of wild bee communities (Hymenoptera: Anthophila) in Swedish boreal forests under different management regimes

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Jaime Ramón Luna Santa-María; [2021]
    Keywords : wild bees; Anthophila; forest management; functional diversity; landscape ecology; inventory diversity; boreal forest;

    Abstract : Intensive forest management has led to forest homogenization with associated changes to biodiversity. Compensatory actions have been taken to counteract the negative effects of these practices on biodiversity, but the effectiveness of these actions depends both on which scale they are evaluated and the group of species they are addressed to.

  6. 5. Capture into mean motion resonance

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Kaltrina Kajtazi; [2021]
    Keywords : MMR; Mean motion resonance; Planetary dynamics; First order MMR; Numerical integration with N-body; Physics and Astronomy;

    Abstract : Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. READ MORE
