  1. 1. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Karnsinee Viriyayudhakorn; [2023]
    Keywords : human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

    Abstract : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. READ MORE

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

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  4. 3. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    University essay from

    Author : Victor Asp; [2022-01-13]
    Keywords : Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Abstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE

  5. 4. Object Detection via Contextual Information

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Lovisa Stålebrink; [2022]
    Keywords : computer vision; machine learning; object detection; deep learning; contextual information; transformers; document object detection; datorseende; maskininlärning; objektdetektion; djupinlärning; kontextuell information; transformer; detektering av dokumentobjekt;

    Abstract : Using computer vision to automatically process and understand images is becoming increasingly popular. One frequently used technique in this area is object detection, where the goal is to both localize and classify objects in images. Today's detection models are accurate, but there is still room for improvement. READ MORE

  6. 5. Investigation of the Plasma delay time in PIPS detectors using the LOHENGRIN spectrometer

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Elizaveta Yakovleva; Ivar Wikander; [2022]
    Keywords : ;

    Abstract : This project has examined the effects of plasma delay time (PDT) and pulse height defect (PHD) for protons, tritons and alpha particles. The goal was to determine PDT and PHD for alpha particles relative to protons, by using data from a subset of measurements taken with a silicon detector of type PIPS at the LOHENGRIN spectrometer.
