  2. 1. The structure and conformation of saccharides determined by experiment and simulation

    Author : Roland Stenutz; B. Meyer; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Abstract : A computer program, CASPER, for sequence determination of oligosaccharides and regular polysaccharides using NMR-data, has been extended to support multiply branched structures. The program has been modified to allow the use of incomplete experimental data since spectral overlap can be a problem even at high fields. READ MORE

  4. 2. Improvement and Assessment of Two-Dimensional Resistivity Models Derived from Radiomagnetotelluric and Direct-Current Resistivity Data

    Author : Thomas Kalscheuer; Laust B. Pedersen; Christopher Juhlin; Roland Roberts; Heinrich Brasse; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electromagnetic geophysics; radiomagnetotellurics; direct-current resistivity; displacement currents; dielectric effect; non-linearity; inversion; regularization; two-dimensional model; model variance; model resolution; data resolution; Geophysics; Geofysik;

    Abstract : Two-dimensional (2-D) models of electrical resistivity are improved by jointly inverting radiomagnetotelluric (RMT) and direct-current resistivity (DCR) data or by allowing for displacement currents in the inversion of RMT data collected on highly resistive bedrock. Uniqueness and stability of the 2-D models are assessed with a model variance and resolution analysis that allows for the non-linearity of the inverse problem. READ MORE

  5. 3. The Potential of b-value Variations as Earthquake Precursors for Small and Large Events

    Author : Paiboon Nuannin; Roland Roberts; Ota Kulhanek; Bjorn Lund; Federico Guendel; Uppsala universitet; []
    Keywords : General; Frequency magnitude distribution; b-values; rockbursts; Andaman-Sumatra region; Zinkgruvan mine; December 26; 2004 earthquake; ALLMÄNT;

    Abstract : The potential of variations of b-values in the G-R relation, logN=a-bM as earthquake precursors for small events (rockbursts) in Zinkgruvan mine, Sweden and for tectonic (large) earthquakes in the Andaman-Sumatra region were investigated. The temporal frequency-magnitude distribution, b(t), of rockbursts in Zinkgruvan mine was examined using high quality data recorded during the period November 1996 to April 2004 with magnitude ranges from Mw= -2.

  6. 4. Anti-phosphorylcholine antibodies in cardiovascular disease

    Author : Roland Fiskesund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the industrialized countries and a growing concern for the developing world. The underlying cause of almost all CVD is atherosclerosis, a process that is characterized by a low-grade inflammation in the artery walls. READ MORE

  7. 5. Elastohydrodynamic lubrication under non-steady conditions

    Author : Roland Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The six papers presented in this thesis consider the effects on elastohydrodynamic lubrication (ehl) of non-steady conditions. The vast majority of ehl investigations, both experiemental and theoretical, utilise steady state conditions, i.e. constant load, velocity, geometry and temperature. READ MORE
