2. 1. Improving interpretation by orthogonal variation : Multivariate analysis of spectroscopic data

   Author : Hans Stenlund; Johan Trygg; Tom Fearn; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; OPLS; PLS; Multivariate Analysis; Orthogonal variation; Chemometrics; hyperspectral images; FTIR; NIR; spectroscopy; Chemistry; Kemi;

   Abstract : The desire to use the tools and concepts of chemometrics when studying problems in the life sciences, especially biology and medicine, has prompted chemometricians to shift their focus away from their field‘s traditional emphasis on model predictivity and towards the more contemporary objective of optimizing information exchange via model interpretation. The complex data structures that are captured by modern advanced analytical instruments open up new possibilities for extracting information from complex data sets. READ MORE

5. 3. Spectroscopic data and multivariate analysis : tools to study genetic perturbations in poplar trees

   Author : Susanne Wiklund; Ulf Edlund; Olav Kvalheim; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; Metabolomics; Degree of methylation; S-plot; SUS-plot; Metabonomics; Poplar; MLR; PLS; OPLS; PCA; Pectin; Wood; Organic chemistry; Organisk kemi;

   Abstract : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. READ MORE

6. 4. Visible spectroscopic diagnostics : application and development in fusion plasmas

   Author : Sheena Menmuir; Professor Elisabeth Rachlew-Källne; Lorella Carraro; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; Plasma physics with fusion; Plasmafysik med fusion;

   Abstract : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. READ MORE

7. 5. Dissolving pulp : Multivariate Characterisation and Analysis of Reactivity and Spectroscopic Properties

   Author : Kristina Elg Christoffersson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Dissolving pulp; reactivity; solid state 13C NMR spectroscopy; NIR spectroscopy; multivariate analysis; cellulose; viscose; Kemi; Chemistry; Kemi;

   Abstract : Various chemical properties can be used to characterise dissolving pulp. The quality of the pulp must be carefully controlled to ensure that it meets the requirements for its intended use and the further processes to be applied. READ MORE
