1. Tools for applied soft ionization mass spectrometry
Sammanfattning : Mass spectrometry (MS) is an important analytical tool. Its most importantadvantages are sensitivity, resolution, and accurate and precise m/zmeasurements. To get the best results from an instrument, the user musthave knowledge of its limitation and requirements. LÄS MER
2. Managing and Exploring Large Data Sets Generated by Liquid Separation - Mass Spectrometry
Sammanfattning : A trend in natural science and especially in analytical chemistry is the increasing need for analysis of a large number of complex samples with low analyte concentrations. Biological samples (urine, blood, plasma, cerebral spinal fluid, tissue etc. LÄS MER
3. Chemometrics : Unravelling information from complex data generated by modern instruments
Sammanfattning : Chemometrics is a discipline dedicated to solving problems arising from complicated analytical systems, combining statistics, mathematics, and computational programming languages.This thesis is based on the work developed in four scientific projects published as papers in scientific journals. LÄS MER
4. Photodetachment of Negative Ions. Experimental Investigations of Threshold and Continuum Structures
Sammanfattning : In this thesis photodetachment studies of atomic negative ions where one or several electrons are detached from a negative ion are presented. Negative ions are unique objects since their formation and destruction mechanisms strongly depend on the correlated motion of the valence electrons. LÄS MER
5. Nutrition transition and the double burden of malnutrition in Indonesia : a mixed method approach exploring social and contextual determinants of malnutrition
Sammanfattning : IntroductionNutrition transition concerns the broad changes in the human diet that have occurred over time and space. In low- to middle-income countries such as Indonesia, nutrient transition describes shifts from traditional diets high in cereal and fibre towards Western pattern diets high in sugars, fat, and animal-source foods.
