  1. 1. Simulations of experimental crack development in ceramic material with notched specimen

    University essay from KTH/Hållfasthetslära

    Author : Clas Dahlin; [2022]
    Keywords : Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Abstract : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. READ MORE

  3. 2. The effects of spinal implant wear debris particles

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Cecilia Thomas; Eslam El Ammarin; [2021]
    Keywords : spine; implant; wear; debris; particles; ryggimplantat; implantatpartiklar; partiklar; implantat;

    Abstract : The goal of this literature study was to study the effects of spinal implant wear debris particles on the body in general, and on microglia cells in particular. The method of the literature study was searching for scientific peer-reviewed papers on the topic.  Spinal implants are used to fix spinal problems such as deformities or injuries. READ MORE

  4. 3. Beam Loading Studies for Cavity Phase and Amplitude Setting

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Staffan Rydén; [2015]
    Keywords : ESS; accelerator; cavity; proton beam; Technology and Engineering;

    Abstract : The purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. READ MORE

  5. 4. Marginal discoloration in dental veneers - Depending on type of cement and removal technique of excess cement

    University essay from Malmö högskola/Odontologiska fakulteten (OD)

    Author : Therese Lindström; Elizabeth Tapia; [2015]
    Keywords : veneers; marginal discoloration; discoloration; cement; removal technique;

    Abstract : Syfte: Syftet med denna studie var att undersöka resistens mot marginala missfärgningar av en adhesivt cementerad keram till emalj beroende på typ av cement, teknik för avlägsnande av överskottscement och kombinationen av de två faktorerna.Metod: 60 extraherade tänder preparerades i emalj med en slipmaskin till en 90° vinkel.

  6. 5. Implant-supported zirconia-based fixed dental prostheses - a literature review

    University essay from Malmö högskola/Odontologiska fakulteten (OD)

    Author : Hannah Fransson; [2014]
    Keywords : fixed dental prostheses; implant-supported; zirconia; Y-TZP;

    Abstract : Det ökade intresset av keramiska material har främst centrerat kring zirkoniabaserade keramer på sistone. Zirkoniabaserade fastsittande broar är ämne för en pågående diskussion. Det finns några få publicerade studier på ämnet men med varierande kvalitet och det finns ingen sammanställning av implantatstödda zirkoniabaserade broar. READ MORE
