  1. 21. Effects of cow-calf contact on feed intake, milk production and energy balance in dairy cows in early lactation

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Carina Tufvesson; [2021]
    Nyckelord :Cow-calf contact system; dairy cow; suckling; feed intake; feeding pattern; milk production; energy balance;

    Sammanfattning : The objective of this study was to compare the production level, feed intake and energy balance in early lactation of non-suckled cows against cows in a cow-driven cow-calf contact (CCC) system. CCC systems have become interesting to evaluate as they are thought to provide a more natural behaviour for both the cow and calf, several studies have reported higher growth and better health in calves kept in these systems.

  3. 22. Nära möten på distans : Tillitsfulla möten i digitala kurser i folkbildningen

    Kandidat-uppsats, Linköpings universitet/Institutionen för beteendevetenskap och lärande

    Författare :Katharina Persson; [2021]
    Nyckelord :popular education; distance courses; trust; social presence; teaching presence; folkbildning; distanskurser; tillitsfulla möten; pedagogisk närvaro; social närvaro; studieförbund.;

    Sammanfattning : Flera studier visar att det tillitsfulla mötet är viktigt inom folkbildningen, men hur skapas det i det digitala rummet? Studien syftar till att bidra med kunskap om strategier och pedagogiska praktiker som stärker det tillitsfulla mötet och skapar en lärmiljö där deltagarna kan vara öppna, dela sina erfarenheter och lära av varandra i nätbaserade kurser. Undersökningen har inspirerats av en designbaserad forskningsmetod. LÄS MER

  4. 23. Promotion of a Market for Hourly Energy Certificates

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Manuel Maria Vidal Dominguez; [2021]
    Nyckelord :;

    Sammanfattning : GHG emissions play a key role in the escalating extreme weather crisis. Commercial and industrial sectors consume almost two-thirds of global end-use electricity; therefore, they have played and will continue to play an important role in driving clean energy in the near term, particularly renewables.

  5. 24. Detailed Balance in Quantum Dot Tunneling

    Kandidat-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Plate; [2021]
    Nyckelord :thermodynamics; quantum dot; quantum tunneling; physics; solid state physics; nanoscience; Physics and Astronomy;

    Sammanfattning : Previously recorded data of electron tunneling in and out of a quantum dot (QD) is used to extract knowledge of the state of the system. Using the detailed balance of the system, it is shown that information about the electron temperature in the lead Te, as well as knowledge about the degeneracies of the states in a quantum dot can be obtained from measurements of the tunneling rates in and out of the QD.

  7. 25. Performance Prediction Program for Wind-Assisted Cargo Ships

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Martina Reche Vilanova; [2020]
    Nyckelord :;

    Sammanfattning : Due to the accelerating need for decarbonization in the shipping sector, wind-assisted cargo shipsare able to play a key role in achieving the IMO 2050 targets on reducing the total annual GHGemissions from international shipping by at least 50%. The aim of this Master’s Thesis project is todevelop a Performance Prediction Program for wind-assisted cargo ships to contribute knowledgeon the performance of this technology. LÄS MER
