  1. 11. The restoration period : a new era in forestry

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

    Author : Ester Andersson; [2023]
    Keywords : historical forest management; past logging; restoration;

    Abstract : In the last 200 years the boreal forests of Sweden have undergone a dramatic transformation. After a long history of high grading the largest trees foresters grew increasingly concerned about the state of logged over forests. The big question was how to regenerate and increase the productivity of sparse forests. READ MORE

  3. 12. Teachers' perspectives on translanguaging in EFL classrooms : Discourses around its use in Swedish upper secondary schools

    University essay from Stockholms universitet/Engelska institutionen

    Author : Marina-Bel Constantine; [2023]
    Keywords : ;

    Abstract : This research focuses on teachers’ perceptions of the term translanguaging in English as a Foreign Language (EFL) classrooms in Swedish upper secondary schools. In Sweden, EFL classrooms are characterized by multilingual environments with a diverse set of learners with different backgrounds. READ MORE

  4. 13. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

  5. 14. Säkra livsmedel i fält : En studie om livsmedelssäkerhet vid Norrbottens flygflottilj

    University essay from SLU/Dept. of Energy and Technology

    Author : Maria Martino Johansson; [2023]
    Keywords : förplägnadstroppen; livsmedelsutbildning; livsmedelskunskap; personlig hygien; kontaminering; livsmedel i fältmiljö;

    Abstract : EU-förordning 178/2002 beskriver att livsmedel inte får släppas ut på marknaden om de inte är säkra för konsumenten. I Försvarsmakten är det delar av den egna personalen som har ansvaret att leverera mat till soldater i fält, vilket kräver noggrann hantering och förberedelse för att säkerställa hög livsmedelssäkerhet.

  6. 15. Constraining the Higgs width in Higgs production associated with a top quark pair

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Benjamin Dahlén; [2023]
    Keywords : Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Abstract : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.
