  1. 11. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia

    University essay from Uppsala universitet/Geofysik

    Author : Vessela Hobson; [2019]
    Keywords : refraction seismics; tomographic inversion; Zambian Copperbelt; copper;

    Abstract : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

  2. 12. Advanced tractography methods: Applied to patients with carpal tunnel syndrome

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Tobias Rosholm; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Introduction: Carpal tunnel syndrome (CTS) is a common condition especially for people with diabetes, obesity or women who are pregnant. Diagnosing CTS has primarily been performed using electroneuronography. READ MORE

  3. 13. Modelling and Simulations of a clinical PET-system using the GATE Monte Carlo software

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Philip Kalaitzidis; [2018]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The increased importance of PET imaging in the health care system has lead to a constant need for improvement and optimisation of scanner systems and their protocols. By utilising the features of the GATE Monte Carlo program one can gain a better understanding of the limitations and possibilities of the system. READ MORE

  4. 14. Deep Brain Stimulation Improves Brain Efficiency in Essential Tremor Patients

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Lena Lindström; [2017]
    Keywords : Deep brain stimulation; Essential tremor; Working memory; fMRI; DBS; ET; WM;

    Abstract : The movement disorder essential tremor can be treated with deep brain stimulation (DBS), where electric current is delivered to deep brain structures through permanently implanted electrodes. In this study, brain activity during working memory performance was measured with functional magnetic resonance imaging in thirteen essential tremor patients with DBS in caudal Zona incerta, a diencephalic nucleus.

  5. 15. Seismic tomography as an instrument for structural evaluation in the Printzsköld and Alliansen ore bodies, Malmberget

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Linus Jonsson; [2017]
    Keywords : Geology; Seismic tomography; LKAB;

    Abstract : The Malmberget deposit is one of the major apatite iron ores in Europe, located in northern Norrbotten. As the mining in Malmberget proceeds deeper more challenges with the stability have been faced. When the stress distribution of a rock mass exceeds the rock strength energy in form of seismic waves is released. READ MORE
