  2. 16. Development of a Noise-Based Method for the Determination of the Moderator Temperature Coefficient of Reactivity (MTC) in Pressurized Water Reactors (PWRs)

    Author : Christophe Demaziere; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point-kinetics; Decay Ratio DR ; Gamma-Thermometer GT ; temperature noise structure of the ; correlation length; boron dilution method; noise analysis; core calculations; dynamic reactor transfer function; moderator temperature coefficient MTC ;

    Abstract : The Moderator Temperature Coefficient of reactivity (MTC) is an important safety parameter of Pressurized Water Reactors (PWRs). In most countries, the so-called at-power MTC has to be measured a few months before the reactor outage, in order to determine if the MTC will not become too negative. READ MORE

  4. 17. Social bodies : family and community level influences on height and weight, southern Sweden 1818-1968

    Author : Stefan Öberg; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; height; weight; body mass index; demography; demographic history; anthropometry; anthropometric history; standards of living; socioeconomic status; socioeconomic differences; resource dilution hypothesis; infant mortality; early life;

    Abstract : This dissertation consists of an introduction, four research papers and one paper describing the data I collected for the studies and how I conducted the study. I collected information on men from conscript inspection lists and linked this to a sample of men in the Scanian Economic Demographic Database (SEDD) born between 1797 and 1950. READ MORE

    Abstract : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. READ MORE

  6. 19. Speciation analysis of butyl- and phenyltin compounds in environmental samples by GC separation and atomic spectrometric detection

    Author : Dong Nguyen Van; Wolfgang Frech; Anders Cedergren; Erwin Rosenberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organotin speciation analysis; species-specific isotope dilution; inductively coupled plasma mass spectrometry; single isotope spike; multi-isotope spike; redistribution; species transformation; preparative liquid chromatography; gas chromatography; line source atomic absorption spectrometry; continuum source atomic absorption spectrometry; Analytical chemistry; Analytisk kemi;

    Abstract : The main goal of the work presented in this thesis is to improve the reliability of existing methods for speciation analysis of organotin compounds Species-specific isotope dilution (SSID) calibration in combination with gas chromatography – inductively coupled plasma mass spectrometry was used to investigate the transformation of phenyltin species during sample preparation. Isotope-enriched phenyltin species were synthesized from corresponding isotope-enriched tin metals. READ MORE

  7. 20. Volume kinetics of glucose solutions given by intravenous infusion

    Author : Fredrik Sjöstrand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Volume kinetics; osmosis; dehydration; rehydration; glucose solutions; glucose; hypovolemia; hypoglycemia; fluids; intravenous fluid therapy; fluid shifts; plasma volume; dilution; plasma dilution; intracellular hydration; central volume.;

    Abstract : Fluid therapy is often cumbersome to plan since the distribution and the elimination of the administered solution are difficult to analyze in the clinical setting. The knowledge of the adequate rate and dose for each individual patient and under various physiological conditions would be very attractive to obtain in order to avoid fluid overload and hyperglycemia.
