1. 1. Quantitative Bioanalysis : Liquid separations coupled to targeted mass spectrometric measurements of bioactive compounds

   Författare :Björn Arvidsson; Jonas Bergquist; Magnus Wetterhall; Gérard Hopfgartner; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Method development; Enhanced microdialysis; Column switching; Liquid chromatography; Capillary electrophoresis; Electrospray ionization; Mass spectrometry; Triple quadrupole; Time-of-flight; Quantitation; Validation; Analytisk kemi;

   Sammanfattning : Performing quantitative analysis of targeted bioactive compounds in biological samples, such as blood plasma, cerebrospinal fluid or extracts from pig liver, put high demands on the ruggedness of the method acquiring the results. In addition to the complexity of the sample matrix, the bioactive compounds targeted for analysis usually have low levels of natural abundance, further increasing the demand on the analytical method sensitivity.

3. 2. Novel Statistical Methods in Quantitative Genetics : Modeling Genetic Variance for Quantitative Trait Loci Mapping and Genomic Evaluation

   Författare :Xia Shen; Örjan Carlborg; Lars Rönnegård; William Hill; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; statistical genetics; quantitative trait loci; genome-wide association study; genomic selection; genetic variance; hierarchical generalized linear model; linear mixed model; random effect; heteroscedastic effects model; variance-controlling genes; Complex Systems – Microdata Analysis;

   Sammanfattning : This thesis develops and evaluates statistical methods for different types of genetic analyses, including quantitative trait loci (QTL) analysis, genome-wide association study (GWAS), and genomic evaluation. The main contribution of the thesis is to provide novel insights in modeling genetic variance, especially via random effects models. LÄS MER

4. 3. Evaluation of Sustainable Urban District Developments : The case of Stockholm Royal Seaport

   Författare :Louise Holmstedt; Maria Malmström; Nils Brandt; Karl-Henrik Robèrt; Jordi Segalàs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evaluation; Follow-up; Sustainable urban development; Sustainable districts; Industrial Ecology; Industriell ekologi;

   Sammanfattning : Urban sustainable development is now seen as one of the keys in the quest for a sustainable world and increased interest in developing sustainable urban districts has become an important feature of urban sustainability. However, if cities and their districts are to be part of this transition, it will be necessary to determine the state and progress of urban developments. LÄS MER

5. 4. Disaster medicine- performance indicators, information support and documentation : A study of an evaluation tool

   Författare :Anders Rüter; Thore Wikström; Maaret Castrén; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; disaster medicine; performance indicators; evaluation; information system; documentation; staff skills; command and control; management; Diasaster medicine; Katastrofmedicin;

   Sammanfattning : The science of disaster medicine is more a descriptive than analytical type. Research, in most instances, has not employed quantitative methods and there is very sparse knowledge based on analytical statistics. One consequence of this is that similar mistakes are repeated over and over. Lessons that should be learned are merely observed. LÄS MER

7. 5. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

   Författare :Mark Lubberink; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

   Sammanfattning : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. LÄS MER
