1. 16. Validation and time series analysis of global stratospheric data sets

   Författare :Ashley Jones; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; OSIRIS; MIPAS; remote sensing; data assimilation; Trend; stratosphere; ozone; linear regression; Odin; validation;

   Sammanfattning : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. LÄS MER

3. 17. On the dynamics of self-esteem : Empirical validation of Basic self-esteem and Earning self-esteem

   Författare :Maarit Johnson; Liisa Keltikangas-Järvinen; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Self-esteem; competence; validation; stability; adjustment; health; Psychology; Psykologi;

   Sammanfattning : The present thesis aims at distinguishing between self-esteem as basic self-love (basic self-esteem) and self-esteem as related to competence (earning self-esteem). In previous research these two phenomena have most often been studied under one and the same self-esteem concept. LÄS MER

4. 18. Prediction of Energy Use of a Swedish Secondary School Building : Building Energy Simulation, Validation, Occupancy Behaviour and Potential Energy-Efficiency Measures

   Författare :Jessika Steen Englund; Bahram Moshfegh; Mathias Cehlin; Jan Akander; Tomas Persson; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; school building; field measurements; energy use; heat power demand; validation; occupancy behaviour; airing; energy-efficiency measures; byggnadssimulering; skolbyggnad; fältmätningar; energianvändning; värmeeffektbehov; validering; brukarbeteende; vädring; energieffektiviseringsåtgärder; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Residential and public buildings account for about 40% of the annual energy use in Europe. Many buildings are in urgent need of renovation, and reductions in energy demand in the built environment are of high importance in both Europe and Sweden. Building energy simulation (BES) tools are often used to predict building performance. LÄS MER

5. 19. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

   Författare :Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; High performance liquid chromatography HPLC ; Analytical biotechnology; Sample preparation; Diode-array-detection DAD ; Mass spectrometry MS ; Validation; Preparative chromatography; Competitive isotherm parameters; Perturbation peak PP method; Kemi; Chemistry; Kemi;

   Sammanfattning : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. LÄS MER

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

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

   Sammanfattning : 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.
