    Abstract : 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. READ MORE

  3. 3. Chemoinformetics for green chemistry

    University dissertation from Växjö, Kalmar : Linnaeus University Press

    Author : Tao Liu; Tomas Öberg; Ian Nicholls; Bert van Bavel; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSPR; PLS; Chemometrics; Chemoinformatics; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; Environmental Chemistry; Miljökemi;

    Abstract : This thesis focuses on the development of quantitative structure-activity relationship (QSPR) models for physicochemical properties, e.g., vapor pressure and partitioning coefficients. Such models can be used to estimate environmental distribution and transformation of the pollutants or to characterize solvents properties. READ MORE

  4. 4. A multivariate approach to computational molecular biology

    University dissertation from Umeå : Kemi

    Author : Fredrik Pettersson; Michael Sjöström; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; biomarker; Drosophila; SNP; linkage; disequilibrium; bioinformatics; computational; molecular; biology; genomics; microarray; SELDI; proteomics; NATURAL SCIENCES Chemistry Theoretical chemistry Bioinformatics; NATURVETENSKAP Kemi Teoretisk kemi Bioinformatik;

    Abstract : This thesis describes the application of multivariate methods in analyses of genomic DNA sequences, gene expression and protein synthesis, which represent each of the steps in the central dogma of biology. The recent finalisation of large sequencing projects has given us a definable core of genetic data and large-scale methods for the dynamic quantification of gene expression and protein synthesis.

  5. 5. Prediction of wood species and pulp brightness from roundwood measurements

    University dissertation from Umeå : Kemi

    Author : David Nilsson; Ulf Edlund; Michael Sjöström; Olav Kvalheim; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Design of Experiments; ISO brightness; Multivariate Image Analysis; Multivariate Modelling; NIR spectroscopy; Norway spruce; PCA; PLS; Roundwood; Scots pine; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. READ MORE
