1. Analysis of Metabolites in Complex Biological Samples Using LC/MS and Multivariate Data Analysis : Metabolic Fingerprinting and Detection of Biomarkers
Sammanfattning : To facilitate early diagnosis of diseases and elucidation of the processes involved in their development and progression, various specific compounds or ‘biomarkers’ are often monitored. The first step is to decide which compounds to analyze. LÄS MER
2. Participation and performance in primary schooling : a study of equality of educational opportunity in Mauritius
Sammanfattning : The aim of the study is to examine the extent to which policies formulated to ensure equality of educational opportunity have been implemented at the primary school level in Mauritius.Universal free primary education was achieved during the early 1970s. LÄS MER
3. Optimering i organisk syntes : betingelser, system, syntesvägar
Sammanfattning : This thesis deals with different optimization problems encountered in organic synthesis. The use of response surface, sequential simplex and PLS techniques, for simultanious optimization of yield and suppression of side reactions is investigated. This is illustrated by an example of enamine synthesis, were a side reaction was a serious problem. LÄS MER
4. Infrared spectroscopy as a tool to reconstruct past lake-ecosystem changes : Method development and application in lake-sediment studies
Sammanfattning : Natural archives such as lake sediments allow us to assess contemporary ecosystem responses to climate and environmental changes in a long-term context beyond the few decades to at most few centuries covered by monitoring or historical data. To achieve a comprehensive view of the changes preserved in sediment records, multi-proxy studies – ideally in high resolution – are necessary. LÄS MER
5. Chemometric and signal processing methods for real time monitoring and modeling : applications in the pulp and paper industry
Sammanfattning : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. LÄS MER
