    This thesis investigates torrent erosion in Lake District mountain catchments,Northern England. A nested research approach was used. Detailed investigations were undertaken at two case study sites (Iron Crag, Raise Beck) together with a survey of torrents across the Skiddaw and Helvellyn massifs. At Iron Crag an annual sediment budget was constructed by monitoring hillslope,channel and fan processes. Particle size characteristics of sediments, and the history of fan development were investigated. Results show channel and bank sediments are the main source of material supplied to the fan. Large rainfall events cause significant change in the channel, banks and fan. The impact of different meteorological conditions on sediment characteristics is complex, however a seasonal cycle of sediment production (winter) and exhaustion (autumn) exists. Historically, initial fan aggradation predates 36 BC, but a rapid phase of deposition began between 1200-1400 AD. Investigations at Raise Beck focussed on a flood that occurred in January 1995 and caused channel avulsion and shallow landsliding. This was reconstructed using a range of geomorphological and sedimentological evidence. Palaeohydrological methods give a discharge between 27- 74 in s-1. whereas as rainfall-runoff values range between 4-6 m3 s-1. The magnitude of the 1995 flood was smaller than two 19th Century events, but would still exceed the capacity of contemporary engineered channels. The regional survey considered the characteristics and importance of torrents,mountain streams, and debris flows; and provided a context for work at the case study sites. The case study sites are distinct members of the regional populations. Raise Beck being the largest (133 ha) and highest (858 m O. D. ); Iron Crag amongst the smallest (2.4 ha) and lowest (600 m O. D. ). Overall, torrents and hillslope debris flows are minor components of the landscape (aerially 2.1 % Helvellyn massif, 0.4 % Skiddaw massif). Sites are preferentially located in regard to altitude and slope.Debris flows are related to geological type. Large torrent floods are relatively rare and can be broadly related to regional flood episodes. Contemporary debris flow activity is of low magnitude and frequency

    Ion torrent-based transcriptional assessment of a Corynebacterium pseudotuberculosis equi strain reveals denaturing high-performance liquid chromatography a promising rRNA depletion method

    Corynebacterium pseudotuberculosis equi is a Gram-positive pathogenic bacterium which affects a variety of hosts. Besides the great economic losses it causes to horse-breeders, this organism is also known to be an important infectious agent to cattle and buffaloes. As an outcome of the efforts in characterizing the molecular basis of its virulence, several complete genome sequences were made available in recent years, enabling the large-scale assessment of genes throughout distinct isolates. Meanwhile, the RNA-seq stood out as the technology of choice for comprehensive transcriptome studies, which may bring valuable information regarding active genomic regions, despite of the still impeditive associated costs. In an attempt to increase the use of generated reads per instrument run, by effectively eliminating unwanted rRNAs from total RNA samples without relying on any commercially available kits, we applied denaturing high-performance liquid chromatography (DHPLC) as an alternative method to assess the transcriptional profile of C. pseudotuberculosis. We have found that the DHPLC depletion method, allied to Ion Torrent sequencing, allows mapping of transcripts in a comprehensive way and identifying novel transcripts when a de novo approach is used. These data encourage us to use DHPLC in future transcriptional evaluations in C. pseudotuberculosis

    Deep Ion Torrent sequencing identifies soil fungal community shifts after frequent prescribed fires in a southeastern US forest ecosystem

    Prescribed burning is a common management tool to control fuel loads, ground vegetation, and facilitate desirable game species. We evaluated soil fungal community responses to long-term prescribed fire treatments in a loblolly pine forest on the Piedmont of Georgia and utilized deep Internal Transcribed Spacer Region 1 (ITS1) amplicon sequencing afforded by the recent Ion Torrent Personal Genome Machine (PGM). These deep sequence data (19,000+ reads per sample after subsampling) indicate that frequent fires (3 year fire interval) shift soil fungus communities whereas infrequent fires (6 year fire interval) permit system resetting to a state similar to that without prescribed fire. Furthermore, in nonmetric multidimensional scaling analyses, primarily ectomycorrhizal taxa were correlated with axes associated with long fire intervals whereas soil saprobes tended to be correlated with the frequent fire recurrence. We conclude that 1) multiplexed Ion Torrent PGM analyses allow deep cost effective sequencing of fungal communities, but may suffer from short read lengths and inconsistent sequence quality adjacent to the sequencing adaptor; 2) frequent prescribed fires elicit a shift in soil fungal communities; and, 3) such shifts do not occur when fire intervals are longer. Our results emphasize the general responsiveness of these forests to management, and the importance of fire return intervals in meeting management objectives

    A comprehensive approach to natural habitats with the ecological points of view as well as those with regard to the aesthetics of the landscape is necessary in projects of the torrent control. The author has been carrying out various research works on the nature-orientated torrent control engineering in the above mentioned sense. In the previous report the author has considered the general ideas and the theoretical backgrounds of the nature-orientated torrent control engineering and introduced some examples of such type of torrent control works in Austria and Bavaria in Germany. Further in 1996 the author has presented a paper which discussed the basic idea of the landscape ecologically reasonable torrent control engineering. During recent several years there are some remarkable developments in nature-orientated torrent control works in Austria. This report is an attempt to introduce and to evaluate such newly developed torrent control works in Austria from the view point of the comprehensive approach to natural habitats

    Le temps d’Anne Hébert au cinéma : Mémoire et altérité dans Kamouraska et Le Torrent

    No full text
    Cet article propose une analyse comparée de deux adaptations cinématographiques d’œuvres d’Anne Hébert : d’une part, Kamouraska, réalisé en 1973 par Claude Jutra, qui adapte le roman éponyme de 1970 ; d’autre part, Le Torrent, réalisé en 2011 par Simon Lavoie, qui adapte la nouvelle liminaire du recueil publié par l’autrice en 1950. En particulier, nous étudierons la représentation du temps qui est à l’œuvre dans ces deux films, afin d’insister sur la complémentarité des démarches choisies par les cinéastes pour adapter la complexité temporelle du récit hébertien : alors que Lavoie, entre autres par le recours à l’héritage cinéphilique, vise la création d’un temps long et continu, quitte à détourner l’esthétique de la nouvelle, Jutra tente plutôt de produire une forme narrative contrariée où le mélange intermittent des temporalités est la traduction du bouillonnement intérieur de son personnage principal. Témoignant de deux époques bien distinctes du cinéma québécois, Kamouraska et Le Torrent soulignent enfin comment un matériau littéraire comme celui d’Anne Hébert, en raison de son ambition, lance au cinéma le défi d’expérimenter ses limites et de réfléchir à ses propres possibilités d’expression.This article proposes a comparative analysis of two cinematographic adaptations of works by Anne Hébert: Kamouraska, directed in 1973 by Claude Jutra, who adapted the eponymous novel of 1970, and Le Torrent, directed in 2011 by Simon Lavoie, who adapts the opening text of the collection published by the author in 1950. In particular, I will look at the representation of time that is at work in these two films, the better to insist on the complementarity of the approaches chosen by the filmmakers to adapt the temporal complexity of Hébert’s narrative: whereas Lavoie, through the use of the cinephilic heritage, aims at the creation of a long and continuous time, even if it diverts the aesthetics of Hébert’s story, Jutra tries rather to produce a contrary narrative form where the intermittent mixture of temporalities is the translation of the inner torments of his main character. Bearing witness to two distinct epochs of Quebec cinema, Kamouraska and Le Torrent finally highlight how a literary material like Anne Hébert’s, because of its ambition, challenges cinema to experiment with its limits and reflect on its own potential of expression

    Ewing sarcoma (ES) is the second most common malignant bone and soft tissue tumor in children and adolescents. Despite advances in comprehensive treatment, patients with ES metastases still suffer poor outcomes, thus, emphasizing the need for detailed genetic profiles of ES patients to identify suitable molecular biomarkers for improved prognosis and development of effective and targeted therapies. In this study, the next generation sequencing Ion AmpliSeq™ Cancer Hotspot Panel v2 was used to identify cancer-related gene mutations in the tissue samples from 20 ES patients. This platform targeted 207 amplicons of 2800 loci in 50 cancer-related genes. Among the 20 tissue specimens, 62 nonsynonymous hotspot mutations were identified in 26 cancer-related genes, revealing the molecular heterogeneity of ES. Among these, five novel mutations in cancer-related genes (KDR, STK11, MLH1, KRAS, and PTPN11) were detected in ES, and these mutations were confirmed with traditional Sanger sequencing. ES patients with KDR, STK11, and MLH1 mutations had higher Ki-67 proliferation indices than the ES patients lacking such mutations. Notably, more than half of the ES patients harbored one or two possible 'druggable' mutations that have been previously linked to a clinical cancer treatment option. Our results provided the foundation to not only elucidate possible mechanisms involved in ES pathogenesis but also indicated the utility of Ion Torrent sequencing as a sensitive and cost-effective tool to screen key oncogenes and tumor suppressors in order to develop personalized therapy for ES patients

    Author Franklin Burroughs, a longtime visitor to the area, reflects on the changes that have occurred over the years at the Forks, where the Dead and Kennebec rivers converge. The hydro dam at Harris makes for paradoxes in the section of the Kennebec River between Harris and the Forks. At night and into the early hours of the morning the turbines are shut off and the flow is reduced, creating a peaceful, low and rocky river. For most of the daylight hours, Harris Dam is opened, releasing a torrent that turns the river wild. The whitewater has spawned a thriving rafting industry in the area
