  1. 11. Play behaviour and maternal relationship between ewe and lambs in Urial sheep (Ovis vignei bochariensis)

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Alicia Josefsson; [2022]
    Keywords : Urial sheep; play behaviour; social play; locomotor play; maternal behaviour; locomotor behaviour welfare; conservation; ex situ; zoo;

    Abstract : Ex situ conservation is done to alleviate the risk of threatened species going extinct and one major conservation aim is increasing the population size. One place working with ex situ conservation is the zoo Nordens Ark in Sweden, and one of their target species is Urials (Ovis vignei bochariensis). READ MORE

  3. 12. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Sjö; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  4. 13. Development of covalent organic frameworks for energy storage applications : DAAQ-TFP COF and MXene composite electrodes for proton cycling

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Simanjit Singh; [2022]
    Keywords : covalent organic framework; DAAQ-TFP; MXene; composite electrodes; 1 3 5-Triformylphloroglucinol; 2 6-Diaminoanthraquinone; nanosheets; exfoliation; ex-situ; Ti3C2Tx;

    Abstract : The demand for today's material resources for energy storage is rapidly increasing and can result in both environmental and political conflicts that can affect the development of electronic devices due to high prices and limitations of raw materials for batteries. In this study, potential future composite electrodes were synthesised with an ex-situ approach by compositing redox-active 2,6-Diaminoanthraquinone and 1,3,5-Triformylphloroglucinol covalent organic framework (DAAQ-TFP COF) with conductive delaminated Ti3C2Tx MXene to maximise the number of redox-active moieties during cycling.

  5. 14. Vilka faktorer påverkar avelsarbetet med snöleoparder i europeiska djurparker?

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Mattias Johansson; [2021]
    Keywords : snöleopard; mortalitet; avelsarbete;

    Abstract : Snöleoparden (Panthera uncia) har länge ansetts hotad i det vilda, både av tjuvjakt, men på senare tid även av habitatförlust från miljöförändringar och människopåverkan. Sedan slutet av1900-talet så har det funnits ett internationellt samarbete i avelsrutiner, och majoriteten av hållarna utanför kinesiska fastlandet är med i samma stambok för att se till att hålla arten genetiskt diversifierad.

  6. 15. Bevarande av den akut hotade ormbunken, Skuggbräken, Polystichum braunii : habitat, hot och åtgärder

    University essay from SLU/Dept. of People and Society

    Author : Eric Sandelin; [2021]
    Keywords : ex situ; in situ; ormbunke; bevarande; nederbörd; luftfuktighet; sporer; förna;

    Abstract : Skuggbräken är en akut hotad ormbunke med en enda känd lokal på Söderåsens Nationalpark, i Skåne. Detta är ett förarbete för att kunna utveckla en bevarandeplan för arten och kunna bevara populationen i odling, ex situ. READ MORE
