1. 1. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Camilla Lane; [2023]
   Nyckelord :Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

   Sammanfattning : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

3. 2. Design and investigation of a pulsating heat pipe for electronic cooling

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Sulafa Hammad; [2023]
   Nyckelord :Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

   Sammanfattning : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. LÄS MER

4. 3. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Samuel Eriksson; [2023]
   Nyckelord :Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

   Sammanfattning : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. LÄS MER

5. 4. Tuning of the ESS Drift Tube Linac using Machine Learning

   Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

   Författare :Johan Lundquist; [2022]
   Nyckelord :Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

   Sammanfattning : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. LÄS MER

7. 5. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
   Nyckelord :co-simulation; water hammer; cavitation;

   Sammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.
