  1. 1. EFFEKTER PÅ UPPSTRÖMSSTABILITETEN I FYLLNINGSDAMMAR : Ändrade porvattentryck till följd av cykliska magasinsnivåer

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Emma Widén; [2024]
    Nyckelord :Vattenfluktuationer; Släntstabilitet; Porvattentryck; Tolererat fel; Finita elementmetoden;

    Sammanfattning : Hydropower is one of the few energy sources with the ability to store a resource and thus regulate electricity production. When the water level in a reservoir changes, this affects the pore water pressures in the dam. LÄS MER

  3. 2. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  4. 3. Kaolin-based coating colors with different rheological and water retention properties : Runnability on a lab-and pilot scale

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Josefine Augustsson; [2023]
    Nyckelord :rheology; runnability; barrierperformance; multibarrier; nanoclay; Speswhite; Capim NP; viscosity; shear thinning; coating performance; reologi; körbarhet; barriärprestanda; multibarriär; nanolera; Speswhite; Capim NP; viskositet; skjuvförtunning; beläggningsprestanda;

    Sammanfattning : Food packaging plays a crucial role in protecting and storing food to keep the products fresh and reduce waste. There is a need to increase the number of paper packages in the food industry to meet the growing demand. LÄS MER

  5. 4. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Dominika Kiesling; [2023]
    Nyckelord :oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Sammanfattning : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

  7. 5. Microfluidic flow splitter shape optimization for high throughput

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Nyckelord :Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Sammanfattning : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. LÄS MER
