  1. 1. Do viscous flows slip?

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Björn Sjösvärd; [2023-12-21]
    Nyckelord :Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Sammanfattning : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. LÄS MER

  3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  4. 3. Investigation of flux dependence on viscosity in ultrafiltration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Peter Bourghardt; [2023]
    Nyckelord :ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Sammanfattning : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. LÄS MER

  5. 4. Increased system sensitivity using fluorescent based immunoassays on the Gyrolab® platform

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

    Författare :Gabriel Lisra; [2023]
    Nyckelord :Gyrolab; fluorescence; sensitivity; immunoassays;

    Sammanfattning : Immunoassays have become an essential tool in several fields of bioanalytics with tremendous advances in sensitivity and formats seen through the last three decades. Many diseases are today diagnosed solely based on biomarker concentrations evaluated through immunoassays. LÄS MER

  7. 5. Skrivande förnäm dam : Konst som hantverk och handelsvara i renässansens Flandern

    Master-uppsats, Uppsala universitet/Konstvetenskapliga institutionen

    Författare :Teresia Strömgren; [2023]
    Nyckelord :Master of the Female Half-Lengths; Technical Art History; Spectrometric analysis; Attribution; The Magdalene; Flemish; 16th Century;

    Sammanfattning : The painting Seated lady writing has undergone a technical investigation where its material characteristics were unveiled using non-invasive analytical techniques employing different wavelengths of the spectrum. The panel was analyzed from a material and a visual culture perspective. LÄS MER
