  2. 21. Multivariate data analysis applied to MRS and MRI studies of aging and spinal cord injury

    Author : Johanna Öberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Magnetic resonance can be used for non-invasive studies of the body without the use of ionizing radiation. Magnetic resonance imaging and magnetic resonance spectroscopy have proven to be valuable utilities for research in life sciences. READ MORE

  4. 22. Modern landfill leachates – quality and treatment

    Author : Hanna Modin; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy metals; European Landfill Directive; Biodegradation; Landfill leachate; Leaching tests; Multivariate data analysis; Organic matter; Sorption filters;

    Abstract : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. READ MORE

  5. 23. Liquid Chromatography Coupled to Mass Spectrometry : Implementation of Chemometric Optimization and Selected Applications

    Author : My Moberg; Jonas Bergquist; Karin E. Markides; Dan Bylund; Douglas B. Kell; Uppsala universitet; []
    Keywords : Analytical chemistry; liquid chromatography; mass spectrometry; tandem mass spectrometry; electrospray ionization; inductively coupled plasma; chemometrics; optimization; multivariate data analysis; design of experiments; response surface model; siderophore; azathioprine; peptide; Analytisk kemi;

    Abstract : Liquid chromatography (LC) coupled to mass spectrometry (MS) offers highly selective and sensitive analysis of a wide variety of compounds. However, the use of hyphenated experimental set-ups implies that many parameters may have an effect on the studied response. READ MORE

  6. 24. Raman Spectroscopy and Hyperspectral Analysis of Living Cells Exposed to Nanoparticles

    Author : Linnea Ahlinder; Lars Österlund; Ioan Notingher; Uppsala universitet; []
    Keywords : Raman spectroscopy; Hyperspectral analysis; Multivariate data analysis; Nanotoxicology; Graphene oxide; Iron oxide; Titanium dioxide; Cells;

    Abstract : Nanoparticles, i.e. particles with at least one dimension smaller than 100 nm, are present in large quantities in ambient air and can also be found in an increasing amount of consumer products. It is known that many nanomaterials have physicochemical properties that differ from physicochemical properties of the same material in bulk size. READ MORE

  7. 25. Continuous monitoring of mineral processes with special focus on tumbling mills : a multivariate approach

    Author : Kent Tano; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Increasing emphasis on productivity and quality control has provided an impetus to research on better methodologies for diagnosis, modelling, monitoring, control and optimisation of mineral process systems. One of the biggest challenges facing the research community is the processing of raw sensor data into meaningful information. READ MORE
