Augley, Julian John. "Plaice (Pleuronectes platessa L.) nursery habitat on the Forth Estuary and the Firth of Forth." Thesis, Edinburgh Napier University, 2007. http://researchrepository.napier.ac.uk/Output/6082.
Full textAbstract:
The nursery function of the Forth estuary and Firth of Forth for juvenile plaice was investigated using several methods. Growth rates of juvenile plaice in the estuary were compared with growth rates of juvenile plaice in the Firth of Forth. Growth was estimated for comparisons between sites because growth is expected to indicate the quality of a particular habitat as a nursery. Growth was estimated at four sites in 2005 using two methods and in 2006 using a single method: 1) Tracking changes in length - frequency distributions of newly - settled plaice over time was used in both years and 2) Plaice were aged to the day using otolith microstructure in 2005 only, and the ages were regressed against length to estimate growth rates as a 'ground - truthing' of method 1). The growth rates of plaice were found to be similar between estuarine and outer firth sites, but lower at all four sites in 2006 than 2005. A temperature - dependent model was used to compare maximum growth rates with estimated growth rates to determine if plaice were growing optimally, and growth was less than optimal at all four sites in both years, with some evidence of density - dependence. A push net was used to sample plaice for length measurements at each site on each sampling date, and efficiencies of the net were estimated to determine actual densities of plaice and whether the net was length selective. No length selectivities were found, however, the efficiency of the net was less than 100 % and lower on muddy sites than on sandy sites. The effect of salinity on growth of juvenile plaice was assessed in a laboratory experiment. Plaice were found to grow faster at salinity 25, next fastest at salinity 30 and lowest at salinity. Assessment of consumption rates showed that the differences were likely to be caused by the effects of salinity on physiological performance of fish. A new method of inferring contribution of juvenile plaice from each habitat to adult recruitment, using stable isotopic composition of plaice otoliths was assessed. Plaice from the estuary could not be distinguished from outer firth plaice on the basis of otolith isotopic composition on the small scale used here, however, the work provides a baseline for this area in larger scale studies. Sediment isotopic composition showed differences between the estuary and outer firth, with differences between sediment types and a detectable influence of marine photosynthesis.

Jayamanne, Sepalika Chandrani. "Population dynamics, biology and ecology of the caridean shrimps : Crangon crangon Linnaeus, Crangon allmanni Kinahan and Pandalus montagui leach in the estuary and Firth of Forth, Scotland." Thesis, University of Stirling, 1995. http://hdl.handle.net/1893/2173.
Full textAbstract:
The population of shrimps from five stations in the estuary and one station in Firth of Forth were sampled for two years from January 1992 to investigate their population dynamics, reproductive biology and feeding ecology. Sampling was carried out at high water and low water, six times a year, by towing an Agassiz trawl, with the Forth River Purification Boards' research vessel, the 'Forth Ranger'. Two residents, Crangon crangon and Pandalus montagui, and a migrant species, Crangon ailmanni, were identified as the main three species of shrimps in the estuary and Firth of Forth. C. crangon was found throughout the estuary while P. montagui was confined to the lower reaches of the estuary. C. alimanni appeared in the estuary in October and left by June. In the Firth of Forth, P. montagui and C. alimanni were the dominant species. The breeding cycle commenced in October, and berried females were found by December/January for all species. Berried females of P. montagui, and both male and female C. alimanni, migrated from the estuary to deeper areas, never to return. C. crangon females with eggs ready to hatch, spent females and larvae all occurred in the estuary. The larvae were present in the estuary from April to October. Larvae of the other two species were not found in the estuary. All species fed mainly on polychaetes, followed by bivalves and crustaceans, which indicated a benthophagous feeding habit. The choice of food depended on the local availability of prey items, and the range of the particular shrimp species within the area; shrimps fed on prey which was abundant in their area of residence rather than moving elsewhere. The Forth Estuary is well utilized by the three species with little competition between them. Although a slow growth rate was observed in C. crangon, the mean condition factor indicated that the conditions in the Forth estuary were close to those normally required for shrimps. The Forth estuary shelters three species of shrimps, with populations, varying between 1992 and 1993, of 1.6-7.7 x 107 for C. crangon, 1.6-2.5 x 107 for P. montagui and 0.7-1.0 x 107 for C. alimanni. These three species contributed to the total annual shrimp production, which ranged from 5.59-17.93 tons at low water in the ratio 40:14:1. Both resident and migratory fish species benefit from this production because shrimps play a key role in the food web, forming the major link between the lower benthic invertebrates and predatory fish.

Hay, Andrew R. "God's shining forth : a trinitarian theology of divine light." Thesis, University of St Andrews, 2014. http://hdl.handle.net/10023/6560.
Full textAbstract:
This thesis seeks an orderly set of theological reflections on the declaration that “God is light” (1 Jn. 1:5). Such talk of divine light, this study argues, must begin with the doctrine of God, namely, with God's light in se and his “shining forth” ad extra towards creatures in the darkness of sin and death. This work therefore follows a precise pathway in expounding this theme. Chapter 1 offers a brief survey of the historical and scriptural uses of the concept of light in order to fix its linguistic and conceptual boundaries. Chapter 2 seeks to reflect upon God's light as the light of his own radiant triune identity, as well as offering a preliminary examination of God's economic, covenantal shining forth to creatures. Chapter 3 gives a much more detailed rehearsal of this act of shining forth by an account of God's light as manifest in the economy of his works with which he lovingly elects, reconciles, and illuminates creatures. Chapter 4 proposes that with the treatment of God's shining forth there belongs a treatment of the light of the church called out of darkness, gathered into the “marvelous light” of God, and set to proclaiming the “excellencies” of God. Chapter 5 concludes this study by examining what bearing the reality of God's shining forth as Father, Son, and Holy Spirit might have on the work and call of theology as an activity of the 'illumined mind'.

Full textAbstract:
This thesis examines the use of a structured design methodology in the design of asynchronous circuits so that high level constructs can be specified purely in terms of signal exchanges and without the intrusion of lower level concepts. Trace theory is used to specify a multi-processor Forth machine at a high level then part of the design is further elaborated using trace theory operations to (insure that the behaviours of the lower level constructs will combine to give the high level specified behaviour without locking or other hazards. A novel form of threaded language to take advantage of the machine architecture is developed. At suitable points the design is tested by simulation. The stack element which is designed is reduced to an electric circuit which is itself tested by simulation to verify the design.

Full textAbstract:
Since the beginnings of archaeology, the study of the past in the Tyne-Forth region has been shadowed by the influence of the political boundary that divides it. Although it has long been acknowledged by archaeologists that the modern polities of Scotland and England did not exist in the past, this divide has continued to affect research design, interpretation and publication. In addition to this, the focus on 'core areas', such as Wessex and Orkney, have long been used to interpret the findings in this region, although the remains found between the Tyne and Forth continue to demonstrate that this area was unique and did not necessarily adhere to the same lifeways as these distant lands. For too long this has caused the area to be seen as a periphery. This research has attempted to consider the Neolithic and Bronze Age of this area as a whole, by ignoring the Anglo-Scottish border and by considering the archaeological remains of the entire region using a single methodology and the data was evaluated to establish the norms for the region first, before relating it to what is known nationally. Experimental work was first carried out to learn more about the material and the ways ceramics can be studied in order to design the research so that it would yield the greatest amount of data. A provenance study of the archaeological remains was then carried out. A total of 333 vessels from the Middle Neolithic to the Middle Bronze Age, including: Impressed Ware, Grooved Ware, Beaker, Food Vessel, Vase Urns, Collared Urns, Cordoned Urns and Bucket Urns were examined. The resulting data were statistically analysed and evidence for cultural interaction, particularly during the introduction of Beakers, was found. The presence local influence on some pottery (previously identified as Neolithic-derived pottery by Millson et al. 2012 in the Milfield Basin, Northumberland) was also recorded throughout the region. Both of these important findings were considered in-depth and a better understanding of the Late Neolithic/Bronze Age transition is proposed for this region.

Full textAbstract:
The zooplankton communities off the north east coast of Scotland, Wee Bankie sand-banks, were studied with traditional net samples and for the first time, for this area, with acoustic methods. A series of zooplankton samples were collected during June 2010 and March/June 2011 together with a set of physical parameters of the water column. Taxonomic analysis of the collected samples enabled the characterisation of zooplankton communities. Neritic communities with oceanic influence were found along the north east coast of Scotland and over the Wee Bankie with spatial variability associated with higher densities of zooplankton inshore. Temporal variability was associated with the expected succession of dominant copepods from spring to summer. An appropriate scattering model, Distorted Wave Born Approximation, was used to predict the target strength of the major zooplanktonic groups and so solve the forward problem to verify a plankton separation algorithm. The algorithm isolated weak scattering targets of zooplankton using three frequencies (38, 120 and 200 kHz) and was used to study the zooplankton spatial distribution during June 2008-2011 in relation to the physical characteristics of the water column. Model predicted target strength for the major zooplanktonic groups was sensitive to orientation for large organisms and material properties for both copepods and euphausiids. The Wee Bankie waters were thermally stratified, with June 2011 the least stratified of all years. Depths of observed maximum backscatter varied in relation to the pycnocline depth and tended to be deeper in offshore stations. The estimated biomass from the observed backscatter increased from 2008 to 2011 but spatial patterns varied from year to year. Although, estimated biomass across years reduced with increasing maximum fluorescence and surface to bottom temperature difference, the same relationship was not evident within year.

Major, Susan. "'The million go forth' : early railway excursion crowds, 1840-1860." Thesis, University of York, 2012. http://etheses.whiterose.ac.uk/3112/.
Full textAbstract:
The travelling masses on their railway excursions were a unique phenomenon in Britain in the 1840s and 1850s. Using a wide range of contemporary press evidence, now searchable online, this research offers new perspectives on the consumption of working class leisure mobility in the early Victorian period, combining cultural and business history. It focuses on the shaping and construction of the railway excursion crowd in Britain at a time of concern for crowd unrest. This study undoubtedly shows how the effects of powerful groups – railway companies, excursion agents, voluntary societies and church groups – who shaped the excursion crowd, are differentiated by the relative strengths of the forces at play at a particular location. In an innovative approach, it positions these powerful groups as early social entrepreneurs, seeking social as well as economic goals. It has also demonstrated an important use of branding as a tool during an earlier period than previously suggested. The role of Thomas Cook has been re-interpreted, he was clearly not the dominant figure so far assumed. For the first time sources have been found which give evidence for accounts of personal experiences on excursions. These uncover underlying themes such as feelings of dehumanisation in crowded cattle wagons and the attractions of sociability. Building on Canetti's analysis of crowd characteristics, this research further reveals aspects of the relationship between the new public spaces formed by the railway excursion, such as the travel space of the carriage or wagon and the station, and crowd behaviour, for example the occurrence of roof travel. Space at the destination was often contested and the research examines the way that powerful groups succeeded in influencing accounts of this contestation.

Full textAbstract:
The main obstacles to HIV-1 eradication are linked to the viral ability to evade immune system and establish a reservoir where virus is transcriptionally latent but able to replicate. IFN action and Restriction Factors (RFs) expression, dominant proteins that target multiple steps of the HIV-1 lifecycle, represent an early line of defence Because of their interplay with viral replication, we would like to study the relationship between RFs and the viral amount in latently infected cells.The first part of this project investigates the expression levels variations of a selected group of RFs (APOBEC3G, BST2, TRIM5α, MX2, SAMHD1, SERINC3/5, IFI16 and STING) in HIV-1 patients during the course of infection before and after ART administration by using Real Time qPCR. The second part of this study deals with the role of IFNα and IFNγ, and their role in the immune system disfunction that has been described during chronic inflammation associated to cancer, viral infection such as HIV-1, and autoimmune-disease. Immune Check Point proteins (ICPs) are a group of inhibitory receptors expressed on the cellular surface of immune cells and trigger immunosuppressive signaling pathways leading to T-cell exhaustion and the expression of immune checkpoint molecules (PD-1, PD-L1, TIGIT, LILRB2). The major aim of this project is to assess the clinical meaning of ICPs expression in HIV-1 chronically infected patients to better characterized their involvement in immune system disfunction.

Full textAbstract:
In the field, a 12-month survey was conducted at 6 stations spanning a wide salinity range in the Forth estuary, to investigate the influence of geographical, seasonal, tidal and physical environmental variables on community structure. Pump samples, in two net fractions (69 urn and 250 um) were collected on spring and neap tides, at high and low water over 9 complete or partial lunar cycles. The use of two concentric nets of differing mesh size extended the size range of specimens caught, and permitted the observation and enumeration of small plankters such as rotifers, copepod nauplii and early polychaete larvae. In early 1982, a clear temporal succession of rotifers> freshwater crustacea> Haranzelleria larvae> Eurytemora was observed. The data acquired on field distribution and abundance were analysed in a variety of ways. The most effective approach was found to be a combination of polythetic, divisive classfication (Twinspan) of sepcies data, followed by Multiple Discriminant Analysis (MDA) of the classification using geographical, seasonal, tidal and environmental data as the discriminating variables. The effects of geographical, seasonal and tidal variation were removed by analysing subsets of the data restricted to one state of a variable at a time; comparison of these restricted analyses with those performed on larger data sets revealed, however, that the relative influence of variables on community structure could be readily discerned even when all variables were considered together. Salinity and geographical position of station were clearly the dominant factors in explaining the species associations defined by classification analysis; organic suspended particulate material was closely associated with these, and temperature also but to a lesser degree. The influences of season and primary production were linked, and were orthogonal to the influence of the dominant variables. Classification analysis identified three main assemblages: the freshwater community; a low-salinity group comprising Eurytemora affinis and Neomysis integer; A neritic assemblage dominated by Acartia spp., Pseudocalanus and Oithona but also including Temora, Centropages and meroplanktonic larvae. Pseudocalanus and Oithona were more persistent than the other neritic taxa, and were more often found in samples of lower salinity and in the autumn and winter. Predation and development rate are two biological factors which directly influence the abundance and distribution of individual taxa. In the laboratory, studies were conducted a) on the rate of predation of Neomysis on Eurytemora and b) the effects of temperature and food availability on the development rate of Eurytemora. Predation rates of adult mysids on adult Eurytemora were estimated to range up to 170 prey/day at 500 prey/litre, and the functional response was adequately modelled by a Type II curve. It was experimentally , demonstrated that predation rates were not reduced in the dark or in the presence of detritus, and it is inferred from this that Neomysis relies on random foraging rather than on visual predation. Estimated predation rates were sufficiently high to suggest that Neomysis predation may, at some times of the year, have a significant effect on Eurytemora population size. Development rates in Eurytemora were not affected by food level, but were quantitatively related to temperature. Development was approximately isochronal, but the duration of the second naupliar instar was consistently longer than that of other instars, especially at lower temperatures. Total estimated development times ranged from 39 days at 8 deg.C to 15.25 days at 20 deg.C, with the effect of temperature being more marked at low temperatures than at high temperatures. The results of the development study were applied to field observations of instar body lengths, in order to estimate daily length increment for 9 dates in 1982. Field observations had indicated that, in contrast to many other studies, body size did not bear a simple inverse relationship to water temperature; whilst the smallest animals were observed during the spring bloom .and midsummer, the largest specimens were collected in September when water temperatures were still high. Highest growth rates were estimated for August (small animals) and September (large animals) ; winter animals, although similar in size to September specimens, had low estimated growth rates. The large size of specimens encountered in September suggests, when considered in conjunction with the low abundance at that time, that a switch may have occurred from investment in reproduction to an investment in somatic growth.

Full textAbstract:
This thesis examines the dramatic implications of the grotesque in Romantic aesthetics, particularly in relation to its poetics of plurality. There have been few studies exploring the drama of the Romantic grotesque, a category that accentuates the multiplicity of the self, while permitting diverse ways of seeing. The post-Kantian philosophy backing Friedrich Schlegel’s Romantic irony provides the most decisive rationalisation of this plurality of identity and aesthetic expression through theatrical play, and forms the theoretical framework for my study. Poetry and philosophy are merged in Schlegel’s attempt to create Romantic modernity out of this self-conscious blurring of inherited perspectives and genres—a mixing and transgressing of past demarcations that simultaneously create the condition of the Romantic grotesque. The other writers examined in this thesis include A. W. Schlegel, Stendhal, Victor Hugo, and Charles Baudelaire. The primary research question that this thesis investigates is: how is the grotesque used to re-evaluate notions of aesthetic beauty? And my answer emerges from a study of those thinkers in Schlegel’s tradition who evolve a modern, ironic regard for conventional literary proprieties. Furthermore, how does the grotesque rewrite ideas of poetic subjectivity and expression? Here, my answer foregrounds the enormous importance of Shakespeare as the literary example supporting the new theories. Shakespearean drama legitimises the grotesque as ontology and literary mode. Consequently, in reviewing unique, critically hybrid texts like the Schlegelian fragments, Stendhal’s Racine et Shakespeare (Racine and Shakespeare), Hugo’s Préface de Cromwell (Preface to Cromwell), and Baudelaire’s De L’Essence du Rire (On the Essence of Laughter), this thesis will use theories of continental Romanticism to reposition the significance of an English aesthetic. Through this, I claim that the Romantic revisioning of the Shakespearean grotesque helps create the ideas of post-Revolutionary modernity that are crucial to the larger projects of European Romanticism, and the ideas of modernity emerging from them.

Full textAbstract:
The estuarine biogeochemistries of Cd, Cu, Mn, Ni, Pb and Zn have been examined. Two adjacent, contrasting estuaries were selected to assess the effects of riverine discharge, hydrodynamic régime and particulate phase composition. Sampling throughout an annual cycle enabled seasonal differences in primary productivity and meteorological conditions to be included. Simultaneous nutrient determinations and fresh water flow measurements were used to assist in the interpretation of metal data. Dissolved Mn profiles in both estuaries are dominated by benthic inputs, a consequence of the reduction of Mn in sub-oxic sediments. Highest benthic fluxes occur in summer, and coincide with dissolved oxygen minima in the upper Forth. High wintertime fluxes are caused by the injection of porewater following sediment resuspension. Dissolved Ni and Zn are remobilised with Mn during summer in the Forth. Dissolved Cd concentrations in both estuaries increase with salinity as a result of chloro-complexation. Both Cd and Cu are remobilised during the breakdown of particulate material. Only about 5% of the Pb is in the dissolved phase. Suspended particulate trace element contents do not vary much within each estuary. The Ca contents, however, increase with distance seaward, since the coastal zone acts as a source of CaCO3 to the estuaries. Non-detrital Mn contents increase in the outer Forth during summer, a consequence of precipitative Mn oxidation. The behaviours of Ni and Zn mimic that of Mn, as they are scavenged from the dissolved phase by newly formed particulate Mn oxides. Particulate Mn contents are higher in summer than in winter, and higher in the well-oxygenated Tay than in the Forth. This is attributed to faster Mn oxidation rates at higher temperatures and dissolved oxygen concentrations. Suspended particulate Cd contents in both estuaries are highest in summer due to the binding of Cd to phytoplankton cells. Partition coefficients in the Forth and Tay follow the order Pb > Mn, Zn > Ni > Cu > Cd.

Full textAbstract:
Le Back and Forth Nudging (BFN) est un nouvel algorithme d’assimilation de données. A l’instar des algorithmes d’assimilation de données préexistants, son rôle est de combiner de façon optimale deux sources d’information d’un système physique : les observations disponibles d’une part et les équations du modèle d’autre part. Un des principaux objectifs de l’assimilation de données est l’estimation de la condition initiale qui est une phase nécessaire pour obtenir des prévisions, notamment en géophysique, domaine dans lequel les modèles sont régis par des phénomènes chaotiques. Ce travail s’inscrit dans une démarche comparative visant à mettre en évidence les atouts et les carences potentiels du BFN. Les deux premiers modèles sur lesquels le BFN a été appliqué dans notre travail sont le système de Lorenz et l’équation unidimensionnelle de Burgers. Ces modèles sont des modèles simples couramment utilisés comme premiers tests car ils sont tous deux non linéaires et chaotiques. Sur ces modèles, les résultats du BFN ont été comparés à ceux fournis par un algorithme de type variationnel. La seconde phase de travail a consisté en l’application du BFN à un modèle réaliste aux équations primitives de l’océan. La mise en œuvre a été effectuée sur NEMO (Nucleus for European Modelling of the Ocean), modèle actuellement utilisé pour l’océanographie opérationnelle. Les différentes méthodes d’assimilation de données étaient encore en phase de développement sur NEMO, la comparaison a simplement été effectuée entre le BFN et le nudging standardThe Back and Forth Nudging (BFN) is a new data assimilation algorithm. Like preexisting data assimilation algorithms, its goal is to combine optimally two sources of information o a physical system : available observations on the one hand and model equations on the other hand. One of the main purposes of data assimilation is the estimation of the initial condition which is an essential step in order to get forecasts, particularly in geophysics where the models are ruled by chaotic phenomena. This work is based on comparative study aiming at highlighting the potentials advantages and lacks of the BFN. The first two models on which the BFM has been applied in this work are the Lorenz system and the unidimensional Burger’s equation. These models are simple models ordinarily used as initial tests since they are both nonlinear and chaotic. On these models, the results of the BFM have been compared to the one provided by a variational algorithm. The second part of this work has consisted in applying the BFM to a realistic primitive equation ocean circulation model. The implementation has been made on NEMO (Nucleus for European Modeling of the Ocean), which is currently used for operational oceanography. The different data assimilation methods still being in process on NEMO, the comparison has merely been carried out between the BFN and the standard nudging

In this thesis we carry out a further study of the back and forth error compensation and correction (BFECC) method. The first part discusses the time reversibility of numerical schemes. Motivated by the BFECC method, a variety of new numeri- cal schemes that aim at improving the time reversibility are developed and studied. We also introduce an interpolation algorithm based on BFECC in this part. In the second part we introduce a new limiting strategy which requires another backward advection in time so that overshoots/undershoots at the new time level get exposed when they are transformed back to compare with the solution at the old time level. This new technique is very simple to implement even for unstructured meshes and is able to eliminate artifacts induced by jump discontinuities in the solution itself or in its derivatives.

Full textAbstract:
The well-being of tourists or visitors within a destination has, until recently, received little attention. Issues relating to the personal safety and health of the travelling public have been highlighted by a number of high profile incidents of terrorist attacks, large scale natural disasters and life threatening epidemics. While such events are devastating in nature and of great concern, for the majority of travellers, health and personal safety are more likely to be impacted on by illness, being involved in an accident or becoming the victim of crime. This thesis contributes to our existing understanding of how tourism can be affected by incidents by selecting a definable geographical area and investigating the available data from official sources to examine the dimensions, scale and nature of visitor-related incidents of crime, road traffic accidents and emergency health care. This audit was undertaken through collaborative research with the Central Scotland Police Force, the Central Scotland Road Accident Investigation Unit and the National Health Service Forth Valley. Primary research was then undertaken with visitors to the area. This in-depth approach looks beyond existing statistics to probe factors contributing to visitor-related incidents, in relation to existing tourism literature. The results indicate that, visitors experience incidents that differ in nature and type from those experienced by local residents, and the times and places they were most at risk also varied. With visitors accounting for less than 10% of the total population, these differences are not apparent in the overall patterns and, therefore, the particular needs of visitors are unlikely to be met through existing measures. This research has the ability to form the basis of improved measures to benefit visitor health and personal safety even though the nature of the visiting population presents challenges in relation to when, where and how such preventative measures are introduced. Visitors are not homogenous and distinct groupings based on perceptions, attitudes and behaviours were found. Therefore, there is a requirement to examine how incidents impact on visitors by distinguishing them from the overall incident figures, but measures to protect visitors also have to be tailored to take cognisance of typologies of visitors.

Full textAbstract:
The Palaeocene and Eocene Forth Field is located in Quad. 9, Block 23/b, adjacent to the East Shetland Platform. The Fourth reservoir consists of a series of massive well sorted, medium to fine grained, turbidite sands which contain biodegraded oil and gas. The textural homogeneity of the Forth sands suggests that sedimentary facies was not a major diagenetic control. The timing of oil migration and the periodicity of oil leakage controlled the relative paragenesis in different sand units. Pervasive ferroan and non ferroan calcite cemented sand horizons dominate the Forth paragenetic sequence. Bitumen filled inclusions within these cements indicate oil emplacement and carbonate cementation occurred simultaneously. Calcite oxygen isotope results suggest East Shetland Platform meteoric water, flushed the reservoir, biodegrading the migrated oil and displacing the original seawater. Biodegradation of oil took place at the palaeo-oil water contact, producing a laterally extensive cementation zone. Frequent oil leakage may have produced a series of different palaeo-oil water contacts which became preferential cementation sites. The Palaeocene Balmoral Field is located approximately 100kms to the south of Forth in Quad. 16, Block 21. To a large extent, the distribution of non-carbonate diagenetic phases in the Balmoral Field is controlled by lithoclast composition and the relative abundance of interbedded shales. Non ferroan and ferroan calcite concretions preferentially precipitated where there were localised accumulations of organic matter. The concretions precipitated at < 500m burial depth, sourced by bacterial oxidation and sulphate reduction of organic matter in meteoric pore fluids. Meteoric water is thought to have been derived from the East Shetland Platform to the north of Balmoral. Oil migrated into Balmoral during the Oligocene, post-dating meteoric flushing. Laterally extensive carbonate cements, formed in association with oil biodegradation, have the potential to compartmentalise a reservoir. The distribution of these cements within Tertiary reservoirs adjacent to the East Shetland Platform is likely to be controlled by the relative timing of meteoric flushing and oil migration.

O presente trabalho analisa, na perícope de 2 Rs 2,19-25, o tema do poder paradigmático em dar vida e tirá-la, abençoar e amaldiçoar, no ministério de Eliseu. Não somente busca evidenciar a função desta perícope como uma unidade, mas também como introdução a todo o ciclo de Eliseu, o qual lidou no seu ministério com o poder de abençoar os obedientes e que respeitam o profeta como genuíno representante de YHWH, e o poder de amaldiçoar aqueles que se lhe opõem. Utilizando o Método Histórico-Crítico e a Análise Narrativa, será evidenciada em 2 Rs 2,19-25 uma mesma trama em dois episódios, servindo de conclusão da seção que engloba todo o conjunto de 2 Rs 2 numa trama unificada. Eliseu é o herói dessa narrativa, o qual tem como objetivo enquanto discípulo tornar-se mestre, o sucessor de Elias. E as simetrias entre 2 Rs 1 e 2 Rs 2 fazem de 2 Rs 1 - 2 a narrativa de sucessão profética de Eliseu moldada à sucessão mosaica.
This actual essay analyzes in the pericope of 2 Kings 2,19-25 the theme of the paradigmatic power in giving life and to pulling it out, to bless and to curse in the Elisha s office. It not only seeks to highlight the role of this pericope as a unit, but also as an introduction to the whole of the Elisha s Cycle, which in his office dealt with the power to bless the obedients and those who respect the prophet as YHWH s genuine representative, and with the power to curse those who oppose the prophet. By using the Historical-Critical Method and the Narrative Analysis, it will be highlighted in 2 Kings 2,19-25 a same plot in two episodes, which serves as conclusion of the section that includes the whole of 2 Kings 2 in an unified plot. Elisha is the hero of this narrative, whose aim as disciple is to become master, the successor of Elijah. And the symmetries between 2 Kings 1 and 2 Kings 2 make 2 Kings 1 - 2 the narrative of Elisha’s prophetic succession molded as mosaic succession.

Full textAbstract:
Canal sediments are an important geochemical indicator of the pollutant status of both the waterway itself and the surrounding area. In this study, sediment samples were collected from the Forth and Clyde Canal, Scotland, UK, and analysed for potentially toxic elements (PTE). Pseudototal concentrations of As (5.54 - 219 mg/kg), Cd (< 0.000557 - 11.0 mg/kg), Cr (44.8 - 883 mg/kg), Cu (39.3 - 618 mg/kg), Fe (35.8 - 72.1 g/kg), Mn (720 - 4460 mg/kg), Ni (42.0 - 154 mg/kg), Pb (93.9 - 2740 mg/kg), Sn (5.36 - 122 mg/kg), and Zn (288 - 3640 mg/kg), measured by ICP-MS, were lower than those reported by British Waterways in 1992 but higher than relevant environmental quality standards, as was the Hg concentration (0.589 - 9.19 mg/kg) determined using CVAFS. The concentration of Fe was relatively constant, but an urban/rural divide was evident in the concentrations of the other analytes, indicting significant anthropogenic input, most likely due to runoff of contaminated urban soils. High levels of analytes at particular locations could often be attributed to historical industrial activities. For site-by-site comparisons, PTE concentrations were normalised to account for organic matter content. The modified BCR sequential extraction was applied to fractionate the PTE content (except for Hg) and estimate their potential mobility. A risk assessment code calculation showed that the mobility order was: Cd/Mn/Zn>As/Fe/Pb>Cr/Cu>Ni>Sn. However, levels of Cd were generally low. The analyte of greatest concern was Pb with up to 1960 mg/kg released between the acid exchangeable and reducible fractions. Concentrations of methylmercury (Me-Hg), monobutyltin (MBT), dibutyltin (DBT) and tributyltin (TBT) were measured using GC-ICP-MS. Levels of Me-Hg (3.44 - 14.1 μg/kg) were < 0.58% of the pseudototal Hg content. The likely source is in situ bacteria-mediated methylation of inorganic Hg. Organotin mean concentrations were low at 28.6 - 71.8, 48.7 - 113, and 48.2 - 189 μg/kg for MBT, DBT and TBT, respectively.

Full textAbstract:
L’objectif principal de cette thèse est de fournir une méthodologie générale pour utiliser une méthode récemment développée d’assimilation de données appelée back-and-forth nudging. Le terme back-and-forth fait référence aux aller-retours dans le temps opéré successivement par cette méthode jusqu’à obtenir une estimation convenable de l’état. La méthode du back-and-forth nudging est une méthode à faible coût connue pour sa simplicité d’implémentation, étant donné qu’elle ne nécessite aucune linéarisation, aucune différentiation d’opérateur complexe et aucun processus d’optimisation, contrairement aux méthodes variationnelles. De plus, elle n’utilise pas non plus d’estimation d’erreur de covariance comme les méthodes séquentielles. Cette méthode est capable de fournir une estimation de l’état sur un intervalle fini de temps, ce qui est particulièrement intéressant pour les problèmes chaotiques à forte sensibilité par rapport à la perturbation de l’état initial ou de certains paramètres du modèle. Premièrement, on cherche à traiter la principale difficulté rencontrée lors de l’utilisation du back-and-forth nudging, qui est de maintenir la convergence de l’erreur continue lors des passages entre la dynamique directe et rétrograde. Pour répondre à ce problème, on montre l’existence d’une fonction de Lyapunov commune aux deux dynamiques. Ce résultat a été montré pour une large classe de problèmes incluant les dynamiques non-autonomes et non-linéaires pour estimer l’état initial mais également les paramètres du modèle. Le second axe est dédié à l’étude de l’attraction des propriétés physique, ce phénomène ayant été observé lors d’expériences passées avec la méthode du nudging standard. Ces altérations sont dues à la nature même de la méthode de nudging, qui consiste à modifier la structure du modèle physique en plus injectant directement un terme d’observation. Nous avons montré, grâce à une analyse de sensibilité, que l’injection des observations par la méthode du back-and-forth nudging est bien moins invasive pour la physique du modèle que par la méthode du nudging standard. Finalement, pour évaluer l’efficacité de la méthode du back-and-forth nudging dans un contexte réel, nous avons réalisé une assimilation de données opérationnelles issues du futur satellite SWOT pour fournir une estimation de l’état dans chaque couche de la région océanique du Gulf Stream. Après étude théorique de la convergence de l’erreur avec un modèle quasi-géostrophique barocline, la méthode a été testée numériquement avec données fortement bruitées, afin de garantir la robustesse de la méthodeThe main objective of this thesis is to provide a general methodology to use a recently developed data assimilation method called back-and-forth nudging. The name «back-and-forth» referred to the successive back-and-forths in time performed by this method until obtaining a suitable estimation of the state. The back-and-forth nudging method is a low-computational method known for its simplicity of implementation, as it does not require any differentiation of complex operators and any optimization process contrary to variational methods. In addition, it does not require estimation of covariance errors as for sequential methods. This method is able to provide a state estimation over a finite-time domain, which is particularly interesting for chaotic problems highly sensitive to perturbation of initial condition or constant parameters. First, we aim to address the main difficulty of back-and-forth nudging method which is to maintain the continuity of error convergence at the switching times between forward and backward dynamics. To overcome this problem, we have shown the existence of a common Lyapunov function for both dynamics. This convergence result has been found out for a large class of non-autonomous and non-linear dynamics to estimate initial condition as well as model parameter. The second axis is dedicated to the study of physical properties alteration, this phenomenon had been noticed in past experiments using standard nudging method. These alterations are due to the very nature of the method, modifying the physical structure by injecting directly in the model an innovation term. We have demonstrated that data injection using back-and-forth nudging far less invasive for the physical dynamics than using standard nudging. Finally, in order to validate the efficiency of the method in a realistic context, we have investigated the assimilation of operational data from the future SWOT satellite mission in order to provide ocean dynamics estimation at every layer of Gulf-Stream's oceanic region. After a theoretical study of error convergence with the multi-layered quasi-geostrophic model, the method has been tested numerically with imperfect data by injecting additional noise, in order to guarantee the robustness of the method

Full textAbstract:
The present study investigated the fish populations of the lower Forth Estuary, east Scotland. Cooling water extraction by the 2400 MW Longannet Power Station (LPS) inevitably removes a certain quantity of fish from the estuary, all of which experience mortality. The present study employed a sampling regime of greater intensity than previous studies to investigate the extent of mortalities from January 1999 - December 2000. Collections of fish impinged on intake screens were made eight times monthly, at LW or HW of spring or neap tides during the day or by night. Marine species dominated the assemblage of fish collected, with sprat, herring, and whiting contributing > 80% of total abundance. Sprat was twice as abundant as herring in 1999, while the proportions were very similar in 2000. Total abundance of all species collected in 1999 was estimated at 1. 09 x 107, while the value of 3.29 x 107 in 2000 was three times larger. These figures were the largest recorded among British estuarine and marine power stations, but were precisely the correct order based on an exponential relationship between total impingement and water abstraction rate established from data from other locations. Validation of the estimated total biomass of fish removed was given by comparison with the known total mass of all materials disposed to landfill. Statistical analysis of impingement data showed that tidal range and season were the most important environmental variables influencing the rate of removal of fish from the estuary. That light was not significant for most species is attributed to high levels of turbidity and the resulting low visibility by day and night. Demersal and benthic fish abundances collected from 1982 - 2000 in 30 annual trawls at three sites in the mid-lower Forth Estuary were analysed. Species tended to be present in greatest abundance at the most seaward of the sites. Patterns of seasonal abundance reflected those observed in the impingement study at LPS, and catches tended to be greatest at L W. Total species richness showed no significant trend over time, whilst total annual abundance of fish captured in trawls showed a significant negative trend. This was largely due to significant declines in the two most abundant species, namely whiting and eel pout, attributable in the latter case to increasing temperatures. Changes in the ichthyofaunal composition were largely driven by whiting, eel pout, cod and plaice. Eight of ten common species showed no significant trend in abundance over the length of the time series, suggesting them to perhaps be at equilibrium densities. Quantities of commercially fished species above minimum landing size limits that were removed by LPS were very low, and restricted to herring and occasional whiting. The quantity of juveniles that could have recruited into the fished populations was expressed as equivalent adults. The values were larger than any previously reported in the UK, primarily due to the quantities of juvenile fish impinged being greater than at any other British power station, and the importance of the Forth as a nursery area for marine species. It was concluded that LPS is the dominant UK power station in terms of magnitude of impingement losses. It may be prudent to consider a precautionary approach to mitigate losses, and to this end options for reduction of the magnitude of impingement are discussed.

This thesis introduces new relative sea level datasets from the Forth and Tay Estuaries dating between 1900 and 2010 and uses these to analyse sea level oscillations, surge components and to influence future sea level projections. Prior to this research, relative sea levels had not been analysed across this region. These datasets were collated and corrected using renowned methods and investigated using Shennan et al.’s (2012) GIA corrections, Torrence and Compo’s (1998) Morlet wavelet transform and Graff’s (1981) sea level maxima analysis. The relative sea level data were then used to support adaptations of two sea level projection models to 2100; the UK Climate Projections 2009 (UKCP09) probabilistic model and Vermeer and Rahmstorf’s (2009) temperature-sea level relationship projections model. These models were, in turn, used to project the impact of extreme relative sea levels on local infrastructure by 2100. This research revealed that relative sea level in the Forth and Tay Estuaries between 1900 and 2010 rose at a rate of 0.27 to 0.56 mm a-1, which is smaller than the global average of 1.7 mm a-1 (Church and White, 2011). Tidal residuals were commonly observed to be approximately 0.4 and 0.7 m at Leith and Dundee between 2003 and 2010, whilst the highest sea level maxima across 5 ports in the region ranged between 3.27 and 4.13 m above OD. Adaptions of the UKCP09 model reduced the original projections for 2100 of between 31.3 and 35.1 cm to between 24.3 and 27.5 cm above the 1990 mean. Similarly, adaptions of the Vermeer and Rahmstorf (2009) model reduced projections from 107.5 cm to between 50.9 and 54.2 cm above the 1990 mean. These adapted projections, when added to the extreme 2100 sea level calculations, suggests that the highest extreme sea level by 2100 could reach the present day quayside heights at selected locations in the Forth and Tay Estuaries. The approach and results are replicable across other regions, thereby refining projections made by previous authors.

Cette étude porte sur les choix d'implantation des espaces funéraires dans les paysages naturels, construits et anciens, par les populations du haut Moyen Age, entre le Ve et le début du VIIIe siècle, dans le Nord de l'Angleterre et l'Est de l'Écosse. Selon les contextes culturels, différentes communautés et leurs élites ont utilisé des caractéristiques naturelles et culturelles dans des mises en scène symboliques de paysages. Entre le Ve et le VIIIe siècle, la région Tyne-Forth devient un carrefour de royaumes bretons et anglo-saxons à partir duquel émerge un des royaumes les plus importants de Grande-Bretagne, la Northumbrie. Cette zone offre la possibilité de comparer l'affichage identitaire de sociétés anciennes de différents royaumes qui se croisent et s'influencent Les pratiques funéraires subissent deux mutations importantes sous l'effet de la christianisation et de la formation de royaume de plus en plus large. Elles sont étudiées afin d'établir si leurs dynamiques temporelles peuvent être interprétées comme les indices d'une évolution des identités culturelles, sociales ou religieuses. On s'interroge sur l'éventuel rôle de traditions relatives à la disposition des morts, dans la création d'identités locales ou régionales. L'analyse du paysage sert aussi à mettre en évidence l'utilisation du paysage naturel et construit pour approcher ces identités. Elle sert également à identifier les réoccupations funéraires de monuments anciens et de le comparer avec celles du reste de la Grande-Bretagne et l'Europe du Nord-Ouest. L'intérêt de cette étude est de mettre en avant les éventuelles pratiques, sociales et symboliques, dissimulées derrière ces réoccupationsThe present thesis focuses on the use of the landscape in early medieval North East England and South East Scotland in the 5th to the 8th centuries -a region recognised as an emerging component of the Northumbrian Kingdom. By the 7th century, Northumbria had become a major political and ecclesiastical power. The chronological frame of this research allows for consideration of the deep political and religious changes that began in the 4th/5th centuries with the departure of the Roman army. The emergence of large kingdoms followed along with the conversion to Christianity and the acceptance and unification of the Christian Faith in the 8th century AD. We here explore the experience of the people who dwelled within this region in the early medieval period from the 5th-8th centuries. li does so by focussing on their funerary rites and practices and how they used their surroundings within funerary ritual to emphasise and signal their collection to place and their identities. Early medieval communities had at their disposal a complex landscape within which they constructed and signalled affiliations by means of interaction with natural and human altered features. Such processes have been argued by many researchers as evidence of the use of the natural landscape and world in the processes of identity creation, with funerary ritual signalling the social and political transformations underway in the organisation of early medieval societies

Full textAbstract:
Disturbance from engineering works is an increasing problem in terrestrial and marine ecosystems throughout the world. Many reported declines in population size, breeding success and body condition have been diagnosed as the result of anthropogenic disturbance, however little is known about the effect of long-term disturbance from large-scale engineering works. Understanding the mechanisms by which animals respond to anthropogenic activities is fundamental to explaining interactions, and resolving potential conflicts between humans and wildlife. This thesis focuses on the factors affecting the habitat use and foraging decisions in wintering shorebirds and wildfowl. The first half of this thesis considers the direct and indirect impacts on waterbirds of a major engineering project in central Scotland; construction of the new Clackmannanshire Bridge at Kincardine-on-Forth. For individual bird species in close proximity to the bridge site, round-the-clock construction work had consequences ranging from neutral to considerably negative. Cormorant Phalacrocorax carbo declined in the area, probably as a result of the disturbance of an important low tide roost. Redshank Tringa totanus, previously abundant in the prey-rich areas adjacent to the construction site, were displaced into poorer areas for most of the construction period; where they may also have suffered from increased interference competition and elevated risk from raptorial predators. Some positive effects of industrial development were also revealed; radio-transmitters combined with tilt-switch posture sensors indicate that Redshank were able to capitalise on the improved nocturnal visibility in areas around Grangemouth docks to assist with foraging and predator detection. Evidence is presented that birds switched foraging strategy (from sight to touch feeding) depending on ambient light levels; whereby artificial light was used in a similar manner to moonlight to assist with prey detection. Redshank also avoided riverine areas at night that were used frequently by day, probably in response to an elevated threat from nocturnal predators. As the predator landscape changes from day into night, birds adopt different strategies to minimise the risk from nocturnal predators. It is clearly important, therefore, that information on nocturnal distributions is available to inform decisions on site management, especially where anthropogenic activity continues throughout the diel cycle. Behavioural decisions were shown to vary widely within a species depending on individual state, metabolic demands and previous exposure to human disturbance. Prey resources were shown to change dramatically over the course of a winter. In response to this decline, the home range of Redshank contracted over a winter season. Similarly, animals responded less and took greater risks in response to experimental disturbance events later in the winter than earlier in the winter, and on days when the temperature was lower. This effect was strongest for individuals occupying heavily disturbed areas, which were possibly already compensating for lost feeding time and a negative energy balance. The results were consistent with the hypothesis that those individuals that respond most obviously to human disturbance were those least likely to suffer fitness consequences. This is the opposite from what is commonly assumed when behaviour is used as an index of disturbance impacts, most notably in the use of flush distance in the design of wildlife buffer zones. In conclusion, this study demonstrated various negative impacts of disturbance, including local displacement, due to construction activity on overwintering waterbirds. It also revealed two key, but poorly understood, phenomena relating to mechanisms for coping with anthropogenic disturbance: routine utilisation of artificial light to extend night-time feeding opportunities amongst Redshank and an adaptive flexibility in escape responses across a range of species under varying conditions of risk.
