  1. 1. Improvements in Energy Efficiency of Vacuum Dewatering of Greaseproof Paper : Simulation of a Triple Vacuum Suction Box in Laboratory Scale

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Björn Öman; [2023]
    Nyckelord :Vacuum dewatering; greaseproof paper; triple vacuum suction box; grammage; energy efficiency; dryness; Vakuumavvattning; greaseproofpapper; trippelvakuumsuglåda; ytvikt; energieffektivitet; torrhalt;

    Sammanfattning : Vacuum dewatering of paper is a heavily energy expensive process, even more so for greaseproof paper, which is one of the main products at Nordic Paper Seffle AB. Due to this being such an energy demanding process, improvements in the vacuum dewatering could save massive amounts of energy. LÄS MER

  3. 2. Study of the temperature profile during industrial coating process

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Gustav Isberg; [2022]
    Nyckelord :Coating; Surface temperature; PVOH; Barrier;

    Sammanfattning : Drying rate during industrial coating application is important to understand because drying a coated paper requires energy. If an unnecessary high amount of energy is used to dry paper, a fast evaporation rate can be achieved which can result in defects of the coated surface. LÄS MER

  4. 3. Crosslinked Cartonboard - Challenges and possibilities

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Malin Elvin; [2022]
    Nyckelord :Cartonboard; crosslinking; mechanical properties; SCT;

    Sammanfattning : The need for sustainable packaging is growing, and plastic waste needs to be reduced. A suitable alternative could be fibre-based packaging and cartonboard, and several actions could enhance this alternative. This study investigates crosslinking, a method to create stronger bonds between the OH-groups in the material. LÄS MER

  5. 4. GPS Tracking Device

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Ivet Shami Jamil; [2022]
    Nyckelord :GPS tracker; SIM808; Telit GM862-GPS; Arduino Uno; Flutter;

    Sammanfattning : The project was performed in collaboration with the company Prevas AB. The aim of the project was to implement a GPS tracking device, or a GPS tracker, that has a hardware setup retrieving the GPS position of an object and then sends the position through a mobile communication module to a smartphone.

  7. 5. Jämförelsestudie för grey scale median (GSM) värde för plack i carotis från ultraljud med två olika bildinställningar

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Crina Teodorescu; [2021]
    Nyckelord :carotid artery; echolucent; grey scale median; GSM; plaque; stroke; ultrasound; arteria carotis; grey scale median; GSM; lågekogen; plack; stroke; ultraljud;

    Sammanfattning : Plack i arteria carotis kan ha olika utseende beroende på innehåll och morfologi. Det kan vara lågekogena eller högekogena plack. LÄS MER
