    Description / Table of Contents: Zusammenfassung Ein kleines, festes Teilchen aus der Handwunde eines Tatverdächtigen wies bei Elektronenstrahl-Mikroanalyse die Eigenschaften von Dentalporzellan auf. Eine Vergleichsprobe von der Zahnbrücke des getöteten Opfers entsprach in ihrer Elementenzusammensetzung weitgehend der gesicherten Partikel. Aufgrund der Untersuchungsergebnisse sah das Gericht einen physischen Kontakt zwischen Opfer und Tatverdächtigem als erwiesen an.
    Notes: Summary A small, solid fragment removed from a wound on a hand of a murder suspect was submitted to electron microprobe analysis and found to have the properties of dental porcelain. A sample of porcelain removed from the dental bridge of the deceased had an essentially similar elemental profile. This investigation assisted the Court by providing valuable objective evidence of a physical contact between the accused and the victim.

    Computer simulation of turbulent swirling flows (1990)

    Notes: Simulation of turbulent swirling flows has been carried out to provide insight on streamline curvature effects. Numerical calculations were based on the control-volume method. Turbulence effects were represented by two-equation turbulence models. The analysis of steady flow between two concentric rotating cylinders showed that the most promising model which incorporates curvature effects is that based on mixing energy developed by Wilcox and Chambers, as opposed to the ad hoc modification to the standard k-∊ model. This model has also been used to simulate the decay of turbulent swirling flow in a short cylinder. A comparison between calculations and experimental results for such flow fields has been presented.

    Changes in iron speciation following a Saharan dust event in the tropical North Atlantic Ocean (2008)
    Elsevier
    In:  Marine Chemistry, 110 (1-2). pp. 56-67.
    Details
    Publication Date: 2015-10-08
    Description: Concentrations of dissolved iron (DFe) and Fe-binding ligands were determined in the tropical Northeast Atlantic Ocean (12-30°N, 21-29°W) as part of the UK-SOLAS (Surface Ocean Lower Atmosphere Study) cruise Poseidon 332 (P332) in January-February 2006. The surface water DFe concentrations varied between 0.1 and 0.4 nM with an average of 0.22 ± 0.05 nM (n = 159). The surface water concentrations of total Fe-binding ligands varied between 0.82 and 1.46 nM with an average of 1.11 ± 0.14 nM (n = 33). The concentration of uncomplexed Fe-binding ligands varied between 0.64 and 1.35 nM with an average of 0.90 ± 0.14 nM (n = 33). Thus, on average 81 of the total Fe-binding ligand concentration was uncomplexed. The average logarithmic conditional stability constant of the pool of Fe-binding ligands was 22.85 ± 0.38 with respect to Fe 3+ (n = 33). A transect (12°N, 26°W to 16°N, 25.3°W) was sailed during a small Saharan dust event and repeated a week later. Following the dust event, the concentration of DFe increased from 0.20 ± 0.026 nM (n = 125) to 0.25 ± 0.028 (n = 17) and the concentration of free Fe-binding ligands decreased from 1.15 ± 0.15 (n = 4) to 0.89 ± 0.10 (n = 4) nM. Furthermore, the logarithmic stability constants of the Fe-binding ligands south of the Cape Verde islands were distinctively lower than north of the islands. The absence of a change in the logarithmic stability constant after the dust event south of the Cape Verde islands suggests that there was no significant atmospheric input of new Fe-binding ligands during this dust event.

    Glucose uptake by Prochlorococcus in the ocean [Ecology] (2013)
    National Academy of Sciences
    Details
    Publication Date: 2013-05-22
    Description: Prochlorococcus is responsible for a significant part of CO2 fixation in the ocean. Although it was long considered an autotrophic cyanobacterium, the uptake of organic compounds has been reported, assuming they were sources of limited biogenic elements. We have shown in laboratory experiments that Prochlorococcus can take up glucose. However,...

    Authors response: British Society of Gastroenterology guidelines on the diagnosis and management of coeliac disease (2016)
    BMJ Publishing Group
    In: Gut
    Details
    Publication Date: 2016-03-10
    Description: We were interested to read the reply to our letter 1 by Kurien et al 2 but consider that they have not made the case for performing a small bowel biopsy in all patients with coeliac disease (CD) to establish the diagnosis. Further support for our view that duodenal biopsy can be avoided in some patients was recently provided by Tortora et al . 3 Kurien et al have also responded to that paper and their two responses suggest a fundamental misunderstanding of the data on which a ‘biopsy avoidance strategy’ is based. It is incorrect of them to assert that their 2008 study 4 ‘clearly refutes’ our suggestion. First, it is essential to use an assay with high specificity (〉97%) but the IgA-class antitissue transglutaminase antibody (IgA-tTG) method they used had an unacceptably low specificity (90.9%) and high false-positive rate (9.1%), a problem recognised with...

Knill et al. , Phys. Rev. A 91 , 032105 (2015) ] to three experimental data sets where conventional analyses failed or required additional assumptions.

    Resilience of SAR11 bacteria to rapid acidification in the high-latitude open ocean (2016)
    Oxford University Press
    Details
    Publication Date: 2016-01-31
    Description: Ubiquitous SAR11 Alphaproteobacteria numerically dominate marine planktonic communities. Because they are excruciatingly difficult to cultivate, there is comparatively little known about their physiology and metabolic responses to long- and short-term environmental changes. As surface oceans take up anthropogenic, atmospheric CO 2 , the consequential process of ocean acidification could affect the global biogeochemical significance of SAR11. Shipping accidents or inadvertent release of chemicals from industrial plants can have strong short-term local effects on oceanic SAR11. This study investigated the effect of 2.5-fold acidification of seawater on the metabolism of SAR11 and other heterotrophic bacterioplankton along a natural temperature gradient crossing the North Atlantic Ocean, Norwegian and Greenland Seas. Uptake rates of the amino acid leucine by SAR11 cells as well as other bacterioplankton remained similar to controls despite an instant ~50% increase in leucine bioavailability upon acidification. This high physiological resilience to acidification even without acclimation, suggests that open ocean dominant bacterioplankton are able to cope even with sudden and therefore more likely with long-term acidification effects.
