MULTISCALE FINITE ELEMENT COMPUTATION FOR CRACK PROPAGATION IN MEDIA WITH MICROSTRUCTURES, AND THE EFFECT OF T STRESS ON THE DIRECTIONAL STABILITY OF CRACKS
No full textAssessment of decadal-scale ecological change at a deep Mid-Atlantic hydrothermal vent and reproductive time-series in the shrimp Rimicaris exoculata
No full textThis study presents a comparison of distribution and abundance of dominant megafaunal species at the TAG hydrothermal mound on the Mid-Atlantic Ridge from 1994 to 2004. A Geographical Information System (GIS) database was compiled from georeferenced observations of faunal abundances at 534 locations on the TAG hydrothermal mound, determined by image analysis of ROV dive footage from November 2004. These data are compared with observations from submersible dives in 1994 to assess changes in the extent and population density of aggregations of the shrimp Rimicaris exoculata at the central black smokers of TAG. The GIS database was also used to assess changes in abundance and distribution of the anemone Maractis rimicarivora by simulating the path of a biotransect conducted in 1994 and 1995. There was no evidence of a decline in the extent of shrimp aggregations at the central black smokers of TAG between 1994 and 2004. This result indicates that occasional exposure to high-intensity submersible lighting, which took place during several scientific expeditions in the intervening period, does not pose an immediate conservation threat to populations of R. exoculata. Similarly, there were no significant differences in the distribution and abundance of anemones between 1994 and 2004. These results indicate a constancy in the identity, distribution and abundance of dominant species at TAG that contrasts with other vent sites where quantitative time-series have been established. The reproductive pattern of R. exoculata was also examined by dissection and direct measurement of oocytes from females collected in September 1994 and November 2004, providing the first comparison of reproductive development in samples from different months for this species. There was no significant difference in oocyte size-frequency distributions of females collected in these samples, indicating a lack of seasonal reproduction in R. exoculata

Telling stories: a metagame description of a conflict
No full textThis paper describes the use of metagame analysis to describe and explore a conflict situation. The analysis was carried out by the author, who was associated with one of the parties in the conflict, for his own benefit. A full description of the analysis is provided. A particular characteristic of the situation was that it was not possible to specify preferences for scenarios for any of the actors with a reasonable degree of confidence. This made the standard metagame analysis approach unworkable, and an alternative approach, involving the development of stories describing a variety of possible future events, was used instead
Author Correction: Long-range chiral exchange interaction in synthetic antiferromagnets
No full textIn the version of this Article originally published, the sentence ‘D.-S.H. wrote the paper with K.L., J.H. and M.K.’ in the author contributions was incorrect; it should have read ‘D.-S.H. wrote the paper with K.L., J.H., M.-H.J. and M.K.’ This has been corrected in the online versions of the Article
Concrete Flow in Diaphragm Wall Panels: A Full-Scale In-Situ Test
No full textFlow processes, taking place during the concreting of diaphragm wall panels (D-wall panels), are of great importance for the quality of the wall. During this phase, the bentonite, present in the excavated trench, should be completely replaced by concrete in a controlled way. In literature several cases are described in which this process resulted in bentonite inclusions in the panel. These inclusions often lead to severe problems, like leakages, for the building pit to be excavated within the diaphragm wall panels. Beside the risks for the building pit, leakages caused by bentonite inclusions can also have large consequences for nearby constructions. In this article, set up and results of a full-scale diaphragm wall test are described. Conclusions are drawn with regard to the influence of several parameters on the flow process and subsequently on the quality of the wall and the risk on bentonite inclusions
