  2. 11. Formality and rational homotopy theory of relative homotopy automorphisms

    Author : Bashar Saleh; Alexander Berglund; Aniceto Murillo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rational homotopy theory; formality; relative homotopy automorphisms; Mathematics; matematik;

    Abstract : This PhD thesis consists of four papers treating topics in rational homotopy theory.In Paper I, we establish two formality conditions in characteristic zero. We prove that a dg Lie algebra is formal if and only if its universal enveloping algebra is formal. READ MORE

  4. 12. Metabolic risk markers and relative survival in patients with aortic stenosis requiring surgery

    Author : Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic stenosis; aortic valve surgery; coronary artery disease; prospective cohort study; risk markers; lipoprotein a ; apolipoproteins; proteomics; troponin T; C-reactive protein; relative survival; observed survival; kardiologi; Cardiology;

    Abstract : Background: Aortic stenosis (AS) is the most common valve disorder requiring surgery in developed countries. The etiology of AS is only partly known.  Identification of new biomarkers in prospective studies could lead to novel insights in the etiology of AS, and possibly lead to improved clinical management.

  5. 13. Others’ income, one’s own fate : How income inequality, relative social position and social comparisons contribute to disparities in health

    Author : Alexander Miething; Olle Lundberg; Monica Åberg Yngwe; Siegfried Geyer; Espen Dahl; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social inequality; health; income; subjective social position; income satisfaction; relative deprivation; Sweden; Germany; Sociology; sociologi;

    Abstract : The overall aim of this thesis is to contribute to a greater understanding of how social inequalities in health evolve causally and to explore the missing links between social position and health in different social and economic contexts.A premise in the thesis is that in affluent societies, not only material aspects and purchasing power linked to income and social positions are important explanations for the health of individuals, but also the relative socio-economic standards in society.

  6. 14. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams

    Author : Hamza Benmakhlouf; Pedro Andreo; Klemens Zink; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Backscatter factors; Diagnostic radiology dosimetry; Mass energy-absorption coefficients; Monte Carlo; Output correction factors; Radiotherapy dosimetry; Reference dosimetry; Relative dosimetry; Small photon fields; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.
