  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Wessén; [2023]
    Nyckelord :Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Sammanfattning : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  3. 2. Event categorisation and Machine-learning Techniques in Searches for Higgs Boson Pairs in the ATLAS Experiment at the LHC

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Milads Emadi; [2023]
    Nyckelord :Particle Physics; ATLAS; BDT; Boosted Decision Tree; Decision Tree; Optimization; Machine Learning; Analysis;

    Sammanfattning : This thesis investigates the pair production of Higgs bosons (di-Higgs events) at the ATLAS experiment in the Large Hadron Collider (LHC), focusing on the channel where one Higgs boson decays into two bottom quarks and the other decays into two tau leptons. The main objective was to determine whether introducing a split in the invariant mass of the decay products from the two Higgs bosons (the di-Higgs mass) and using this as an analysis variable improves the sensitivity of the Boosted Decision Tree (BDT) machine learning algorithm to the di-Higgs signal.

  4. 3. Comparison of In Vivo Intramuscular Fat Quantification Techniques in MRI

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Pien Derikx; [2023]
    Nyckelord :Fat-water separation; Dixon technique; Intramuscular fat quantification;

    Sammanfattning : People with cerebral palsy (CP) may develop muscle contractures, which are defined as a loss of joint range due to an increase in passive muscle stiffness [1]. Computer models suggest that intramuscular fat can increase muscle stiffness [2]. LÄS MER

  5. 4. Dietary fiber content and composition in heritage wheat

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Lisa Andersson; [2022]
    Nyckelord :Heritage cereals; wheat; dietary fiber; fructan; Dacke; Dala Lantvete; Källunda; Ölandsvete;

    Sammanfattning : Wheat is the main food source in the world. A secured production has however been threatened by environmental changes in combination with the need of producing more food for a growing population. As a result, there has been an increasing interest in finding new crop varieties susceptible to abiotic stress. LÄS MER

  7. 5. Modeling and simulation of chromatographic separation in Modelon Impact

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Oliver Thelander; [2022]
    Nyckelord :Chemical engineering; Simulering; Modellering; Kromatografi; Adsorption; Modelica; Modelon Impact; Recirkulation; Simulation; Modeling; Chromatography; Recirculation; Technology and Engineering;

    Sammanfattning : The aim of this master thesis is to implement a previously modeled chromatographic adsorp-tion process from MatLab into the Modelon Impact, a simulation software. Modelon Impact is using Modelica as language syntax that is useful for creating a large system of interconnected models that has the potential to work in different configurations. LÄS MER
