  1. 1. Röjningsstrategiers effekt på stubbskottsutveckling och granmedelhöjd i blandbestånd av gran och björk

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

    Author : Max Lindhe; Jonathan Samuelsson; [2023]
    Keywords : röjningsstrategi; stubbskott; björk; gran;

    Abstract : Olika röjningsstrategier förväntas påverka stubbskottsbildning hos röjstubbar av vårtbjörk (Betula Pendula Roth) och glasbjörk (Betula Pubescens Ehrh), men relativt få studier har gjorts på området, varför det finns utrymme för vidare forskning. Det huvudsakliga syftet med den här uppsatsen var att undersöka skillnaderna i stubbsskottsutveckling till följd av olika röjningsstrategier. READ MORE

  2. 2. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johansson Vivika; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  3. 3. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Filip Hörberger; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

    Keywords : N.spruce-birch stands; monoculture; thinning treatment; mixed forest;

    Abstract : Picea abies L. Karst (N. spruce) monocultures dominate the forest landscape of southern Sweden due to their suitability for the prevalent site conditions, well established silviculture, and profitability. However, disturbances such as windthrow, bark beetle damage, and Heterobasidion root rot pose a risk to N. READ MORE

  5. 5. Förändringsupplevelser i PCT och PFPP - Paniksyndrom ur olika perspektiv
