  2. 11. Validation and application of objective measures of obesity and physical activity : studies in pregnant and non-pregnant adults and in infants

    Author : Anna Gradmark; Paul W Franks; David Fields; Umeå universitet; []
    Keywords : physical activity; validation; body composition; abdominal adipose tissue; methods; accelerometer; pregnancy; insulin sensitivity; offspring;

    Abstract : Background Excess adipose tissue and low physical activity are two major determinants for chronic diseases such as type 2 diabetes and cardiovascular disease.  Understanding these relationships requires accurate and precise measures of body composition and physical activity, and most existing observational studies lack such measures.

  4. 12. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC

    Author : Robert Arnell; Torgny Fornstedt; Andreas Seidel-Morgenstern; Uppsala universitet; []
    Keywords : Analytical chemistry; Liquid chromatography; Preparative LC; Chiral LC; Multi-component LC; Adsorption isotherm; Tracer-pulse method; Inverse method; Inverse method on plateaus; Peak deformations; Chiral drug-protein interactions; Analytisk kemi;

    Abstract : This thesis concerns the development and validation of methods for characterization of multi-component preparative LC systems. Measurements of competitive adsorption isotherms are performed to gain detailed information about the interactions inside the chromatography column. READ MORE

  5. 13. Development of the Stress Strategy Test as a personnel selection instrument

    Author : Rolf Federmann; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; military personnel selection.; stress; cognition; personality; personnel selection; Serial Colour Word Test; Stroop effect; Stroop test; Stress Strategy Test;

    Abstract : The thesis concerns the development of a computerised test, termed the Stress Strategy Test (SST), intended for use in a personnel selection and placement context. A similar but less extended form of that test, termed the Stroop Strategy Test, developed first, was adjudged to be somewhat less effective as a selection instrument. READ MORE

  6. 14. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

  7. 15. Input Calibration, Code Validation and Surrogate Model Development for Analysis of Two-phase Circulation Instability and Core Relocation Phenomena

    Author : Viet-Anh Phung; Pavel Kudinov; Cristophe Demaziere; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reactor system code; input calibration; code validation; surrogate model; two-phase circulation flow instability; in-vessel core relocation; genetic algorithm; artificial neural network; Reaktorsystemkod; indata kalibrering; kodvalidering; surrogatmodell; två-fas cirkulationsflöde; instabilitet; härdrelokering i reaktortanken; genetisk algoritm; artificiella neurala nätverk; Fysik; Physics;

    Abstract : Code validation and uncertainty quantification are important tasks in nuclear reactor safety analysis. Code users have to deal with large number of uncertain parameters, complex multi-physics, multi-dimensional and multi-scale phenomena. READ MORE
