  2. 1. Microbial life deep underground : From anaerobic cultures to reconstructed genomes

    Author : George Westmeijer; Mark Dopson; Hans Røy; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Continental deep biosphere; microbial ecology; anaerobic enrichment cultures; Candidatus Desulforudis audaxviator; Thiobacillus denitrificans; flow-cells; Mikrobiologi; Microbiology; Ecology; Ekologi;

    Abstract : The deep biosphere refers to the vast ecosystem of life beneath the Earth’s surface, residing in the fractured bedrock and pores of rocks, largely isolated from solar energy. These fractures enclose an important reservoir of groundwater that contains microorganisms active in processes such as the uptake of inorganic carbon, sulfur cycling, or the degradation of organic matter.

  4. 2. Studies on economic growth and inflation : theory and empirics

    Author : George Adu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis consists of four independent papers. Paper I examines the effect of environmental policy on economic growth in a small open economy in a neoclassical framework with pollution as an input. READ MORE

  5. 3. Colonoscopy : Introduction and development, completion rates, complications and cancer detection

    Author : George Dafnis; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Colonoscopy; population-based; indications; completion rates; complications; colorectal cancer; sensitivity; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : In a population-based study in the county of Södermanland, 6066 colonoscopies performed in 4304 patients from 1979 to 1995 inclusive were evaluated. As indications, bleeding increased and polyps and unclear x-ray findings decreased. Surveillance (cancer, polyps, colitis) was fairly stable. READ MORE

  6. 4. Spontaneous abortion : risk factors and measurement of exposures

    Author : Lena George; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Case-control study; caffeine; cotinine; environmental tobacco smoke; epidemiology; fetal karyotype; folate; maternal smoking; pregnancy; repeated spontaneous abortion; risk assessment; smoking cessation; spontaneous abortion; validation study;

    Abstract : The overall objectives of this thesis were to increase the understanding of the etiology of spontaneous abortion and repeated spontaneous abortion, and to evaluate possibilities of exposure assessment during pregnancy. Data from a Swedish population-based case-control study of spontaneous abortion, performed in Uppsala County 1996-98, formed the base for the three first studies of the thesis. READ MORE

  7. 5. Urea and Non-Protein Nitrogen Metabolism in Infants : With Special Reference to the Sudden Infant Death Syndrome (SIDS)

    Author : Mary George; Sten Lindahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Urea; non-protein nitrogen metabolism; SIDS; drinking water nitrate concentration; carbon dioxide production; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Abstract : A large amount of non-protein nitrogen, in the form of urea and ammonium, is present in human breastmilk; however its physiological role in the infant is as yet not fully understood. It has been hypothesized that an insufficient enteric metabolism of urea could play a role in the sudden infant death syndrome (SIDS). READ MORE
