1. 26. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Harald Agelii; [2023]
   Nyckelord :Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

   Sammanfattning : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. LÄS MER

3. 27. Combustibility study of resin for warm magnet coils used at CERN

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Juan Carlos Lopez Santiago; [2023]
   Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

   Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

4. 28. Comparison of muscle oxygen kinetics between occluded and non-occluded dynamic low-intensity exercise performed till failure : A quantitative study

   Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

   Författare :Natalie Smith; Josefine Johansson; [2023]
   Nyckelord :venous occlusion; muscle oxygenation kinetics; blood flow restricted exercise; ischemia; exercise failure; low-intensity strength training; Near-infrared spectroscopy;

   Sammanfattning : Aim: To examine local muscle oxygen kinetics when performing wrist extensions till failure in an occluded versus non-occluded state, to compare the perceived ratings of pain and local muscle exertion, and analysing presence of gender differences. Methods: Twenty-one healthy individuals (mean age 25,6±3. LÄS MER

5. 29. Biopolymers processed and used as enzyme carriers

   Master-uppsats, KTH/Fiber- och polymerteknologi

   Författare :Dániel Mészáros; [2023]
   Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

   Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

7. 30. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap

   Master-uppsats, KTH/Materialvetenskap

   Författare :Simone Quintè; [2023]
   Nyckelord :Steel scrap sorting; stainless steel; Chromium; Nickel; Molybdenum; alloys recovery; Laser Induced Breakdown Spectroscopy; revenue modeling; CO2 emissions modeling; Stålskrot Sortering; rostfritt stål; Krom; Nickel; Molybden; återvinning av legeringar; Laserinducerad nedbrytningsspektroskopi; intäktsmodellering; Modellering av CO2-utsläpp;

   Sammanfattning : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.
