  1. 21. Cohesive and Spectroscopic properties of the Lanthanides within the Hubbard I Approximation

    Författare :Inka Laura Marie Locht; Igor Di Marco; Olle Eriksson; Annalisa Fasolino; Mikhail I. Katsnelson; Tim Wehling; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lantanides; rare earths; cohesive properties; volume; bulk modulus; magnetism; magnetic properties; photoemission spectroscopy; XPS; BIS; Hubbard I Approximation; DMFT; DFT; RSPt; Full Potential Linear Muffin-tin orbitals; 4f electrons; localization; bonding; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : We describe the rare-earth elements using the Hubbard I approximation. We show that the theory reproduces the cohesive properties, like the volume and bulk modulus, and we find an excellent agreement between theory and experiment for the (inverse) photo emission spectra of the valence band.

  3. 22. Estimation of hazard ratios from observational data with applications related to stroke

    Författare :Guilherme Barros; Jenny Häggström; Marie Eriksson; Daniel Nevo; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; survival analysis; causal inference; hazard ratios; marginal hazard ratio; stroke; balancing; Statistics; statistik;

    Sammanfattning : The objective of this thesis is to examine some challenges that may emerge when conducting time-to-event studies based on observational data. Time-to-event (also called survival) is a setting that involves analyzing how different factors may influence the length of time until an individual experiences the event of interest. LÄS MER

  4. 23. An epidemiological perspective on heart and lung weight in cardiac and intoxication deaths

    Författare :Torfinn Beer; Carl Johan Wingren; Anders Eriksson; Britt-Marie Stålnacke; Kimberly Molina; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart weight; lung weight; organ weight; autopsy; forensic pathology; Bayesian analysis; cardiac hypertrophy; fatal intoxication; Forensic Medicine; rättsmedicin;

    Sammanfattning : The main purpose of a medico-legal autopsy is to determine the cause and manner of death. A forensic pathologist makes assessments of this using several sources of information, one of which is the discrepancy between measured organ weight and reference values. LÄS MER

  5. 24. Snus use and mortality : associations, potential mechanisms, and socioeconomic aspects

    Författare :Marja Lisa Byhamre; Patrik Wennberg; Marie Eriksson; Jan-Håkan Jansson; Magnus Lundbäck; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; snus; Swedish snuff; smokeless tobacco; mortality; cardiovascular; cancer; risk factor; metabolic syndrome; C-reactive protein; vitamin D; testosterone; family medicine; allmänmedicin; befolkningsstudier; Population studies; epidemiologi; Epidemiology; invärtesmedicin; Internal Medicine; Medicine; medicin;

    Sammanfattning : Snus is a smokeless tobacco product made of a moist powder of ground tobacco. It is used mainly in the Nordic countries, although increasingly popular internationally. The Swedish snus tradition dates back to the seventeenth century, and it is now used daily by about 23% of the male and 6% of the female population. LÄS MER

  7. 25. The impact of organizational and temporal factors on acute stroke care in Sweden

    Författare :David Darehed; Marie Eriksson; Mathias Blom; Eva-Lotta Glader; Johan Niklasson; Bo Norrving; Ole Morten Rønning; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in-hospital bed occupancy; stroke unit; The Swedish Stroke Register; organizational factors; temporal variation; stroke thrombolysis; door-to-needle time; quality of care; outcomes; Medicine; medicin;

    Sammanfattning : Background: Acute stroke carries a high risk of morbidity and death, but early treatment can improve outcomes. Intravenous stroke thrombolysis (IVT) is one such treatment, it is however time-sensitive and show better outcomes the sooner it is given. LÄS MER
