  1. 1. Bond strength between zirconia restoration and titanium abutment after recementation, with different surface treatments.

    University essay from Malmö universitet/Odontologiska fakulteten

    Author : Amanda Cervenka; Hanna Ekdahl; [2020]
    Keywords : bond strength; recementation; surface treatment; titanium abutment; zirconia;

    Abstract : SAMMANFATTNING Syfte Syftet med studien var att utvärdera hur olika ytbehandlingar på titandistanser inför recementering påverkar bindningsstyrkan hos konstruktionen. Material och metod 30 provkroppar bestående av zirkonia (Z-CAD HTL, Metoxit, Thayngen, Switzerland) adhesivt cementerade (Panavia™ V5, Kuraray Noritake, Tokyo, Japan) till titandistanser (Elos Accurate® Hybrid Base, Elos Medtech, Timmersdala, Sweden) delades in i tre grupper med 10 provkroppar i varje grupp: kontrollgrupp (C), sandblästrade med aluminiumoxid (AA) och skrapningsgrupp (S).

  2. 2. Bond strength of zirconia- or polymer-based copings cemented on implant-supported titanium bases

    University essay from Malmö universitet/Odontologiska fakulteten

    Author : Lisa Hua; Oddbratt Eliann; [2020]
    Keywords : ;

    Abstract : Syfte: Syftet med denna in-vitro-studie var att utvärdera bindningsstyrkan mellan zirkonia eller polymerbaserade överkonstruktioner cementerade på implantatstödda titanbasar med olika adhesiva cementsystem samt utvärdera om förbehandling (sandblästring) av polymerbaserade konstruktioner förbättrar bindningsstyrkan. Nollhypotesen är att oberoende av materialval, förbehandling och de olika adhesiva cementsystemen som används kommer det inte att påverka bindningsstyrkan. READ MORE

  3. 3. Keen for Green - A Study of Pricing in the Secondary Green Bond Market

    University essay from Lunds universitet/Företagsekonomiska institutionen

    Author : Rickard Anderkrans; Patrik Johannesson; [2019]
    Keywords : Green bonds; Panel data; Issuer fixed effects regression; Capital asset pricing model; Investor preference; Business and Economics;

    Abstract : The emerging green bond market is a novel research area with only a few studies being published in recent years. The increase in interest from issuers, investors, and academia shows the clear need for further investigation of the pricing dynamics affecting the green bond market. READ MORE

  4. 4. Topology-guided analysis and visualization of charge density fields

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiLinköpings universitet/Tekniska fakulteten

    Author : Elvis Jakobsson; [2019]
    Keywords : Visualization; Topology; Charge density; Direct Volume Rendering; Crystal structure;

    Abstract : Direct volume rendering techniques for scalar fields make use of transfer functions to map optical properties to the field; the field can subsequently be visualized through the drawing of isosurfaces in the volume spanned by the field. The utility of this approach is limited in the case of nested or clustered structures with the same isovalue and further does not easily allow for quantitative measurements of the visualized data.

  5. 5. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Viktor Eriksson; [2019]
    Keywords : Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

    Abstract : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.
