  2. 1. Unveiling catalytic species in suspension/solution-based reactions by in situ X-ray absorption spectroscopy

    Author : Ning Yuan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The palladium (Pd) and ruthenium (Ru) species in several attractive catalysts have been probed using X-ray absorption spectroscopy (XAS). The study of catalyst evolution in suspension- and solution-based reactions was the primary aim. It was achieved by performing in situ XAS experiments on Pd and Ru over the course of the reactions.

  4. 2. Antiphagocytosis by Yersinia pseudotuberculosis : role of the YopH target proteins

    Author : Ming Yuan; Maria Fallman; Tommy Nilsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Cas; Fyb; mAbp1; SKAP-HOM; Yersinia pseudotuberculosis; YopH; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The enteropathogenic bacterium Yersinia pseudotuberculosis binds to β1 integrins on a host cell via its surface protein invasin. This event stimulates signal transduction to the actin cytoskeleton of the eukaryotic cell, which allows the cell to engulf the bacterium that is attached to its surface. However, the pathogen Y.

  5. 3. Trinucleotide repeats and neuropsychiatric phenotypes

    Author : Qiu-Ping Yuan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Trinucleotide; repeat expansion; psychiatric disorder; gene; spastic paraplegia;

    Abstract : Genetic studies of affective disorders have yielded several chromosomal regions suggestive for linkage. Linkage analysis was performed in five families with unipolar affective disorder, collected from northern Sweden. Four candidate regions on chromosomes 16, 18, 21 and 4p were excluded. READ MORE

  6. 4. Wideband Sigma-Delta Modulators

    Author : Xiaolong Yuan; Svante Signell; Jakob Wikner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sigma-delta modulator; feedforward; reconfigurable; quadrature bandpass filtering; Electronics; Elektronik;

    Abstract : Sigma-delta modulators (SDM) have come up as an attractive candidatefor analog-to-digital conversion in single chip front ends thanks to the continuousimproving performance. The major disadvantage is the limited bandwidthdue to the need of oversampling. READ MORE

  7. 5. Development of Functionalized Protein Materials

    Author : Yusheng Yuan; Niclas Solin; Olle Inganäs; Qi Zhou; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Many proteins are available as side-streams from food production, and in some cases even from industrial waste-streams. This means that proteins are available in large scale and at a relatively low price. As protein are highly complex molecules it is interesting to try to use protein as starting materials in for applications in materials science. READ MORE
