  1. 1. Phase Unwrapping MRI Flow Measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Mio Liljeblad; [2023]
    Nyckelord :phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Sammanfattning : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. LÄS MER

  3. 2. Content determination of explosive precursors and narcotic salts using 35Cl-nuclear magnetic resonance

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Sandra Bergqvist; [2023]
    Nyckelord :Nuclear magnetic resonance NMR ; explosive precursors; narcotic salts; method validation.;

    Sammanfattning : Explosive precursors and narcotic salts are chemicals contributing to an undesirabledevelopment of the Swedish society, both in terms of criminal activities and harm to the environment. Reducing the illegal use of these chemicals is important in the work towards a safer society. LÄS MER

  4. 3. Study, Design and Optimization of Micro Coil for NMR Applications

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Yuxuan Lu; Xinhang Li; [2023]
    Nyckelord :NMR;

    Sammanfattning : Nuclear Magnetic Resonance (NMR) has emerged as a powerful tool for the iden-tification and quantification of substances. A critical component within the NMRapparatus is the radio frequency coil, which determines to some extent the sen-sitivity of the NMR device. LÄS MER

  5. 4. Synthesis and analysis of potential metabolites of ADB-5´Br-BUTINACA

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Alaa Malekshahineia; [2023]
    Nyckelord :metabolites; NPS; synthetic cannabinoids;

    Sammanfattning : In recent years, there has been a rise in the use of New Psychoactive Substances (NPS) that mimic the effects of controlled drugs and licensed medicines, which have become a significant public health concern globally. Synthetic cannabinoids, a rapidly expanding category of NPS, with much higher potency and binding affinity to the cannabinoid receptors than ∆9-tetrahydrocannabinol (THC), have led to serious psychiatric complications and other adverse effects.

  7. 5. Metabolic effects of various carbohydrates and fibre in dog food

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Fanny Bergevi; [2022]
    Nyckelord :dog; whole grain wheat; peeled oats; whole grain rye; metabolic profiles; metabolic pathways;

    Sammanfattning : The lack of scientific studies regarding dog nutrition highlights the need for future studies, especially when we know the importance of food in relation to health. The variety of ingredients in commercial dog food is huge. LÄS MER
