  1. 1. Beständigheten hos brandimpregnerat trä

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Filip Engström; Hannes Psajd; [2024]
    Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

    Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

  3. 2. FRÅN VITT TILL GRÖNT, RÖTT ELLER BRUNT: Kan blindering åtgärdas med kunskap vi redan har?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Annica Drotz; [2023-11-07]
    Nyckelord :blanching; oil paint; bloom; paint layer; accelerated aging; consolidation;

    Sammanfattning : Blanching is a common phenomenon affecting the binding medium within the paint, resulting in an abnormality of the paints light scattering. Multiple studies have confirmed that the change is the result of pore formation within the binding medium caused by humidity or water damage. LÄS MER

  4. 3. Internationalization Barriers in the Healthtech Industry : A study of barriers that business-to-business Software-as-a-Service healthtech companies experience when expanding organically from Sweden to other European markets

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Julie Salicath Aasen; Sara Samie Ghafarokhy; [2022]
    Nyckelord :Barriers; Expansion; Internationalization; Healthtech; Software-as-a-Service; Business-to-Business; Barriärer; Expansion; Internationalisering; Healthtech; Software-as-a-Service; Business-toBusiness;

    Sammanfattning : As a result of the aging and growing population in Europe, the demand for healthcare services continues to rise. It is therefore important to streamline the healthcare sector to manage the growing demand. One way to do this is by implementing digital-health solutions. LÄS MER

  5. 4. Development and Scaling Up of Test Protocol to a Full-Scale Filter Rig to Investigate Soft Particle Filtration Efficiency in Biofuel Blends

    Master-uppsats, KTH/Kemiteknik

    Författare :Saurabh Shinkhede; [2021]
    Nyckelord :Heavy duty transportation; fuel filter clogging; soft particles; biofuel blends; filter test rig; Tunga transport; igensättning av bränslefilter; mjuka partiklar; biobränsleblandningar; filtertestrigg;

    Sammanfattning : Kommersiella tunga transporter står för en stor del av utsläppen av växthusgaser. För att minska det globala fotavtrycket hos kommersiella fordon är det vanligt att använda biodrivmedel som ”drop in” bränslen. LÄS MER

  7. 5. Accelerated aging of cellulose-based composites in different climate environments : A project provided by Biofiber Tech Sweden AB

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Karin Dungner; Ebba Eskner; Amanda Holst; Nina Petersson; Maria Pokosta; John Eric Roos; [2021]
    Nyckelord :Cellulose; Composites; Accelerated aging; Tensile testing; Color intensity; Polymer; Climate chamber; LDPE; Cellulosa; Kompositer; Accelererad åldring; Dragprov; Färgintensitet; Klimatkammare; Polymer; LDPE;

    Sammanfattning : This paper reviews the effects of accelerated aging with increased humidity and temperature on cellulose-based composites. The composites consist of a matrix of plastic reinforced with cellulose fibers. The company Biofiber Tech Sweden AB provided four different composites and a conventional polyolefin as reference.
