  1. 1. "Vi kan inte packa in allt i bubbelplast" : En studie om förskollärares syn på riskfylld lek i förskolans utomhusmiljö

    Uppsats för yrkesexamina på grundnivå, Karlstads universitet

    Författare :Frida Nygren; Olivia Möberg; [2024]
    Nyckelord :ECEC; outdoor environment; risky play; scaffolding; Förskola; riskfylld lek; stöttning; utomhusmiljö;

    Sammanfattning : From previous experiences, different perceptions of risky play have been noticed. This study therefore aims to shed light on the early childhood education center (ECEC) teachers’ approach to and perceptions of risky play in ECEC outdoor environment. LÄS MER

  3. 2. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Nyckelord :Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Sammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER

  4. 3. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Henrik Östberg; [2023]
    Nyckelord :Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. LÄS MER

  5. 4. Optimization of sterilization method for cultivation of filamentous fungi on lemon waste

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Oliver Conradsson; David Ljungberg; [2023]
    Nyckelord :Lemon waste; lemon waste; sterilization; autoclavation; fungal cultivation; bubble column bioreactor; fungal biomass Rhizopus delemar;

    Sammanfattning : Consumption of citrus fruits and citrus juice production creates wastes, which could be valorized by using it for cultivating fungi. Before cultivation, the medium needs to be sterilized though autoclavation. Larger volumes used when autoclaving requires longer heating cycles and therefore runs the risk of degrading the medium to a greater extent. LÄS MER

  7. 5. A glimpse from inside the "EU bubble": A qualitative interview study of European youth doing traineeships at the EU institutions

    Master-uppsats, Lunds universitet/Europastudier

    Författare :Terese Andersson; [2023]
    Nyckelord :Internship; EU; youth mobility; youth migration; youth influence; European youth identity; qualitative interview; European studies; European Union; Social Sciences;

    Sammanfattning : European citizens demand more bottom-up debates in opposition to the existing elite-driven voices heard within European policymaking. The youth is one of the groups which demands more participation and involvement, and the EU is partly involving young people by having trainees at the EU institutions. LÄS MER
