  1. 1. Utmattning av implantat-förankrade bro-konstruktionermed ett frihängande led och två olika fixturdiametrar. En pilotstudie

    Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

    Författare :Ahmed Yassin; Mohammed Al-Haideri; [2023]
    Nyckelord :Cantilever; Dental implants; Fixed dental prosthesis; Fatigue; Fracture strength; Implant angulation; Brotthållfasthet; Dentala implantat; Fast protetik; Frihängande led; Implantatvinkling; Utmattning.;

    Sammanfattning : Purpose: The purpose of this study is to evaluate how implant-supported fixed dental prosthesis (FDP) restorations with a cantilever at abutment level resist fatigue by dynamic loading and thermocycling depending on the fixture diameters.   Material and method: The study involved two groups with three specimens in each group, based on the diameter of the fixture, 3.

  3. 2. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Yoseph Abraham; [2023]
    Nyckelord :;

    Sammanfattning : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). LÄS MER

  4. 3. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Aayush Desai; [2023]
    Nyckelord :Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Sammanfattning : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. LÄS MER

  5. 4. A study of Oracle Cloud Infrastructure : Demonstration of the vulnerability or reliability of certain services through penetration attacks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shanly Feller; [2023]
    Nyckelord :Oracle Cloud Infrastructure; penetration testing; security practices; cloud security; vulnerability assessment.;

    Sammanfattning : This thesis aims to assess the security of Oracle Cloud Infrastructure (OCI) through penetration testing of some of its services. Targeted at cloud, cybersecurity, governance, and compliance professionals as well as administrators or cyber enthusiasts in general, this research uncovers specific best practices to OCI. LÄS MER

  7. 5. Utan motivering och tillämpning av försiktighetsprinciper. Anmälningar om åldersdiskriminering under covid-19 pandemin.

    Master-uppsats, Lunds universitet/Socialhögskolan

    Författare :Tina Falk; [2022]
    Nyckelord :Equality Ombudsman; Elderly; Vaccination; Astra Zeneca.; Social Sciences;

    Sammanfattning : The aim of this study was to describe the complainants view of age discrimination in connection with the covid-19 through reports which have been sent to the Equality Ombudsman during a two-years period: 2020 - 2021. The data material has been analyzed through Paul Ricoeur´s analysis model 1. A model in which the texts contain an essential power. LÄS MER
