description: The area investigated for this thesis is the western end of the Iveragh Peninsula, Co. Kerry, southwest Ireland. The rocks in the area are predominantly of Old Red Sandstone facies, totalling over 6600m in thickness, and were deposited near the northern fault-bounded margin of the extensive half-graben feature known as the Munster Basin. Towards the end of the basin's history, continental conditions were replaced by marginal marine as the sea transgressed into the area from the south. The objectives of the study are to provide a description of the poorly known sedimentary facies from this part of the basin, to interpret these in terms of processes and environments of deposition, and to review and clarify long-standing issues arising from the poorly known age and correlative significance of the lower parts of the Iveragh succession. Mapping and detailed logging of selected sections have been carried out. A number of facies types are identified, and interpretation of these in the light of palaeocurrent and other evidence suggests a terminal-fan model for sediment deposition. Sediment transport was largely by unconfined episodic sheet floods , with transport consistently from the north. Calcrete formation, although limited, suggests a semi-arid climatic setting. Fish fossils and plant miospores date the basin-fill as Upper Devonian in age, possibly just extending down into latest Middle Devonian. Miospore assemblages allow regional correlation with other areas in the Munster Basin. Minor igneous intrusive and extrusive rocks in the area have been mapped and described, and consist of contemporaneous acid pyroclastics as well as late or early post-Devonian intrusives. One dyke in the area is considerably younger, probably Tertiary in age. A thick tuff bed, the Keel Tuff Bed, is traced over part of the area, and may have regional correlative significance.
MODELLING PORE-LEVEL PROPERTIES OF POROUS MATERIALS

Publisher: name: University of Plymouth

description: Pore-Cor is a 1.2 Mbyte Fortran 77 software package, which uses information from mercury porosimetry curves, supported by image-analysed electron micrographs, to generate a three-dimensional representational model of the pore-space within a porous material. As a result of this project, a much-improved version has been produced. The mercury intrusion curves for the simulated structures now converge automatically onto the experimental curves, so reducing the simulation time from several days to less than an hour. A further time economy has been provided by the incorporation of an improved permeability routine, reducing the calculation time from 10 minutes to 30 seconds. Modifications have allowed non-homogeneous structures to be modelled, in simulation of real samples of banded, vuggy and clay-included sandstones. Porosimetry measurements have been made for Fontainebleau sandstone into which small amounts of illite, a simulated clay deposit, had been introduced by hydrothermal crystallisation. Despite having no effect on porosity, the effects on simulated permeability could be successfully assessed. The causes of hysteresis, i.e. the trapping of a non-wetting fluid in a porous medium, were also investigated. The need for higher quality experimental data to feed into the Pore-Cor software has led to improved measurement and analysis methods for the porosimetry. A new spreadsheet-based iterative programme, named Pore-Comp. provides a unique method of measuring the compressibility (or bulk modulus) of the solid phase of a porous medium, and this has been used to examine the effects of silicate micro-crystallinity and latex binders on the compressibility of paper-coating formulations. Using the cryo-stage of the electron microscope, the retention of mercury in some paper coating formulations has been investigated further.

THE DEVELOPMENT OF DIATOM-NUTRIENT PALAEOLIMNOLOGICAL INFERENCE MODELS FOR UK LOWLAND RESERVOIRS
Creators: name: BURGESS, AMY
Publisher: name: University of Plymouth
Year: 2004

description: Deterioration of UK lowland reservoir water quality through cultural eutrophication is of concern for both water supply and conservation. This study represents the first attempt to develop diatom-based palaeolimnological inference models for the assessment of eutrophication in UK lowland reservoirs. Models are developed from a 46-reservoir calibration set comprising surface sediment diatom assemblages and contemporary environmental data measured seasonally between May 1999 and October 2000. Following removal of outliers the dataset spans a total phosphorus (TP) gradient of 12-242 µgl ˉ¹ (mean = 63), a chlorophyll-α (Chla) gradient of 1.8-25.5 µgl ˉ¹ (mean = 63) and a conductivity (EC) gradient of 119-781 µScm ˉ¹ (mean = 424). Reservoir mean annual epilimnetic TP, Chla and EC are reconstructed using weighted averaging (WA) and weighted average partial least squares (WAPLS) techniques. Jack-knifed error statistics for the best performing models (WA inverse deshrinking), are comparable to those reported from similar studies. The plankton provides the dominant habitat for diatom growth in reservoirs, thus plankton-only models are also created and perform almost as well as models developed using all taxa. Examination of seasonal diatom plankton populations indicates that many taxa display defined seasonal growth preferences. The transition of frustules from live to sedimentary assemblages reveals that reservoir productivity and hence sedimentation rates affect subsequent representation of seasonal diatom populations in surface sediment samples. Fossil diatom assemblages in sediment cores from two contrasting reservoirs are analysed and the UK lowland reservoirs TP, EC and Chla inference models applied to reconstruct reservoir nutrient histories, yielding a fuller account of ecological change than either model alone. Twentieth-century reconstructions from Blackbrook reservoir illustrate an early history of limited impact mesotrophy, followed by a shift to cultural eutrophication during recent decades. Daventry reservoir shows a history of nutrient enrichment to hypertrophy, followed by subsequent re-oligotrophication as a result of pollution-reduction measures. Available historical data support the broad trends inferred by the diatom-based inference models. UK lowland reservoirs are considered suitable environments for the development of diatom-nutrient inference models and their application where intact sediment profiles exist.
THE MICROSTRUCTURES OF ESTUARINE PARTICLES
Creators: name: TITLEY, JOHN GRAHAM
Publisher: name: University of Plymouth
Year: 1988

description: A systematic study of the surface properties of suspended and bed sediments from the Tamar Estuary and Restronguet Creek was carried out using a nitrogen adsorption technique. The surface areas and porosities of the particles were determined using BET theory and capillary models applied to the gas adsorption isotherms. The surface areas of the suspended particles collected on axial transects of the Tamar Estuary ranged between 8 and 22 m²/g. The highest values were found for particles in the turbidity maximum region. These appeared to be related in a complex way to both particle size and the chemical composition of the particles.
PRODUCTIVITY MANAGEMENT OF THE CACAO AGRO-FOOD SYSTEM IN TABASCO (MEXICO): A FITNESS APPROACH
Creators: name: NAVARRETE, CESAR JESUS VAZQUEZ
Publisher: name: University of Plymouth
Year: 2007

description: The farming industry and the agro-food system as a whole are now required to adapt to a challenging and more competitive environment. How the food industry can fit itself into such environment is the main question that is addressed in this study. The fitness approach, an exploratory framework, is applied in order to study the Cacao Agro-food System (CAPS) in Tabasco. Mexico. The final sample consisted of 356 farmers, 37 curing plants, 6 wholesaling firms, and 7 chocolate firms. An anatomical model using correspondence analysis was adopted to understand the main features of every industry in the CAPS. The Pitness Appraisal Instrument (FAI) was constructed and applied to determine the relationships between factors and aspects of organisational configuration with 5 key performance indicators of the CAPS farming industry. The anatomy of CAPS revealed that it is based on raw and bulk products, has a potential to diversify vertically and horizontally, and has a dual structure private and union related -which is not appropriate to deal with issues such as free market pressures or lethal fungal diseases. Results of the PAI analysis revealed that both the factors and the aspects of organisational configuration are significantly related to performance indicators. Indeed, 14 of the 20 productivity management elements are significantly related to performance indicators. Moreover, the results show that a set of fittest solutions, rather than a unique solution, exists among farmers. Visualisation of the productivity management elements reveals that participation of organic cacao, education levels, and price setting exert the strongest influence on productivity indicators. The key implication of this study is that both efficiency and effectiveness are the two valid strategies that enable the farming industry to cope with the challenging and competitive environment. The Policy makers should be aware of a set of solutions (fitness landscape) instead of just focusing on individual (often narrow) solution.

description: Cosmological accretion shocks created during the formation of galaxy clusters are a ubiquitous phenomenon all around the Universe. These shocks, and their features, are intimately related with the gravitational energy put into play during galaxy cluster formation. Studying a sample of simulated galaxy clusters and their associated accretion shocks, we show that objects in our sample sit in a plane within the three dimensional-space of cluster total mass, shock radius, and Mach number (a measure of shock intensity). Using this relation, and considering that forthcoming new observations will be able to measure shock radii and intensities, we put forward the idea that the dark matter content of galaxy clusters could be indirectly measured with an error up to around 30 per cent at the $1σ$ confidence level. This procedure would be a new and independent method to measure the dark matter mass in cosmic structures, and a novel constraint to the accepted $Λ$CDM paradigm.

The Middle to Late Cretaceous microbiostratigraphy (foraminifera) and lithostratigraphy of the Cauvery Basin, Southeast India
Creators: name: Tewari, Archana
Publisher: name: University of Plymouth
Year: 1996

description: The present research is on the Cretaceous microbio- and litho-stratigraphy of the Cauvery Basin, Southeast India. The planktonic and benthonic foraminifera are used to establish microbiostratigraphic zonations for the mid-Cretaceous succession in the Basin; leading to the first proposal of a benthonic foraminiferal zonation scheme. The schemes are primarily defined for regional application. In the absence of a formal lithostratigraphic classification for the Cretaceous succession in the Basin, a revised lithostratigraphy, in line with standard stratigraphic procedure, is proposed. The systematic taxonomy of the foraminifera studied is documented and revised in line with Western standards. The study shows that, in contrast to the standard European forms, the fauna from the Cauvery Basin is composed of more robust individuals. The study also shows some interesting differences in the planktonic foraminifera from the standard Tethyan assemblage. Comparative studies indicate a longer time range for some of the "index" species and more ornamented forms in the Cauvery Basin. The study records two levels, ( I ) in the late Albian and (2) from the late Cenomanian to mid-Turonian, when anoxic conditions developed in the Basin. These anoxic events record major taxonomic changes in the planktonic foraminiferal assemblage. The study shows that the anoxic events had a major affect on the microfaunal community and that the post anoxic microfaunal population was dominated by more robust and heavily ornamented individuals. The planktonic foraminifera are used to identify the mid-Cretaceous sea-level changes in the Basin. The pattern of evolution and expansion of the planktonic foraminifera suggest a continuously rising sea-level in the mid-Cretaceous; with four periods of major transgressions. These levels are, at the late Albian, mid-Cenomanian, late Cenomanian-early Turonian and mid-Turonian. The pattern of sea-level changes in the Cauvery Basin followed , in general, the global sea-level curve, but has been influenced by local factors particularly tectonics. A pilot study demonstrates how palaeontology (including ichnology) in conjunction with sedimentology and stratigraphy is used to apply sequence stratigraphy concepts to the late Turonian-Coniacian succession in the Basin. A comprehensive study of Teredolites-infested fossil wood documents the morphological characters of the wood and its palaeoenvironmental significance. The study shows that there exists a close link between the influx of the fossil wood and sea-level dynamics.

description: Plasma spectrometry is now a widely accepted technique for the determination of the elemental composition of a wide range of sample types. The successful introduction of volatile organic solvents has however been limited, due to the resulting high solvent loading of the plasma and subsequent plasma instability. The design, function and application of a number of novel desolvation systems have been investigated in this study to decrease this loading and facilitate operation with volatile organic solvents.

description: Mature oaks covering the full range of the indigenous Quercus species, from the oak woods of Dartmoor and its periphery, were sampled each month during the growing season for the presence of cynipid oak galls. The distributions of galls within sites, within trees and within leaves were recorded, and an investigation into the factors which affect them was made. The distributions of galls on oaks were found to be influenced by climatic and topographical factors as well as by the behaviour of the wasps and the taxonomic status of the host oak. Oaks in exposed situations tended to host more species of gall causing wasps, in higher numbers than oaks in sheltered situations within the woodland canopies. In addition; Q.robur hosts harboured more gall species and larger numbers of an individual species than Q.petraea hosts. Oaks of introgressed hybrid status (Q.x rosacea) had gall populations ranging from levels less than were found for Q.petraea to levels higher than occurred on Q.robur. Partitioning of gall species occurred both vertically and horizontally within the canopy, and within individual leaves. Work on the ecologies of the gall causing wasps indicate that the adults may be able to distinguish between the indigenous oak taxa, when selecting suitable oviposition sites. Some gall species are solely restricted to Q.robur, a situation probably determined by some unidentified physiological property of Q.robur favourable to cynipid gall induction. An investigation into the life cycle of Andricus quercuscalicis Burgsdorff, and its effects on the natural regeneration potential of oaks was also undertaken. Up to 100% of acorns on oaks infested by A.quercuscalicis may be galled, which has serious consequences on the subsequent germination potential of the acorns. Only one or two trees in a wood are infested by A.quercuscalicis in any year, and as long as this pattern exists it is not thought likely to pose a serious threat to the natural regeneration of oaks.

description: In this paper we discuss a technique for selectively loading a particle into a magneto-gravitational trap using the sublimation of camphor to release particles from a tungsten probe tip directly into the trapping region. This sublimation-activated release (SAR) loading technique makes use of micropositioners with tungsten probe tips, as well as the relatively fast rate of sublimation of camphor at room temperature, to selectively load particles having diameters ranging from $\SI{8}{\micro \meter}$ to $\SI{100}{\micro \meter}$ or more. The advantages of this method include its ability to selectively load unique particles or particles in limited supply, its low loss compared to alternative techniques, the low speed of the particle when released, and the versatility of its design which allows for loading into traps with complex geometries. SAR is demonstrated here by loading a particle into a magneto-gravitational trap, but the technique could also be applicable to other levitated optomechanical systems.

description: Abstract

The function of fungus, particularly Candida albicans, in dental caries is a serious problem for oral health. One intriguing new therapy option for antifungals is nanoformulations. This study explores the fight against the dangers that fungi—most notably Candida albicans, a key cause of tooth problems like caries—pose to oral health. It looks into the possibility of using nanoformulations to treat fungal infections; in specifically, it compares herbal-synthesized nanoparticles to leaf extract from Acacia catechu and research that are related to them. The properties of silver oxide nanoparticles made using herbal extracts were described, and inhibition zones were used to gauge how effective they were against Candida albicans. The herbal nanoparticles outperformed the positive control, ketogluconate, in their noteworthy antifungal effects. Their scientific fascination was further enhanced by detailed imaging obtained using scanning electron microscopy, which revealed a structure that was clearly broccoli-like. With their strong antifungal properties directed against Candida albicans, these herbal nanoformulations hold great promise for controlling dental caries. However, more research—including clinical trials—is necessary to properly understand and make use of their effectiveness in real-world dental care settings.

description: The iron oxide-water interface is of interest not only in geochemical and environmental processes, but also in fields ranging from corrosion to photocatalysis. The structure of α-Fe2O3 (001) surfaces is not fully understood, and questions have arisen recently concerning different terminations of (001) terraces; a so-called Fe-termination is expected, but under some conditions an O-termination may also be possible. Ultra-high vacuum (UHV) scanning tunneling microscope (STM) studies report evidence for an O-termination in coexistence with an Fe-termination, but other studies find no evidence for an O-termination. Molecular mechanics studies suggest that an O-termination should be possible in an aqueous environment. An O-termination could result from dissolution; if Fe atoms were to dissolve from an Fe-termination, an O-termination would presumably result (and vice-versa). We imaged hematite (001) surfaces in air and aqueous solution using STM. To aid interpretation of the images, we use a resonant tunneling model (RTM) parameterized using ab initio calculations. Our STM and RTM results are consistent with mixed O- and Fe-terminated (001) surfaces. For acid-etched surfaces we find evidence for a periodic (with wavelength of 2.2 ± 0.2 nm) arrangement of nominal O- and Fe-terminated domains. Two different borders between domains should occur, one in which the Fe-termination is high relative to the O-termination, and the reverse. The different domain borders have significantly different heights, consistent with RTM calculations. This agreement allows us to conclude that the Fe-termination is topographically high on most terraces. Surface domains are observed in aqueous solutions at the atomic scale, and appear to be very unreactive on tens-of-seconds time scales at pH 1.
Essays in international macroeconomics

description: This dissertation is composed of three chapters that study topics in the fields of international macroeconomics and international finance. Chapter 1 studies how news about future Total Factor Productivity (TFP) impacts the investment channel and, in turn, affects the susceptibility to financial crises such as Sudden Stop episodes. A Sudden Stop episode is a crisis stemming from a rapid and severe reduction in economic capital inflows. The study employs a small open economy model with capital accumulation and a representative agent borrowing against an occasionally binding collateral constraint to explore the influence of persistent news shocks on financial stability and optimal policy response. It shows that news shocks increase the probability of Sudden Stops and require an active and substantial policy rate intervention. In a similar framework of endogenous Sudden Stop crises triggered by occasionally binding borrowing constraints, chapter 2 examines policy interventions available in a two-sector small open economy. It distinguishes between the taxes on household debt policy that targets the borrowing activity in the economy and a tradable revenue policy that allocates resources across the two sectors, consistent with an exchange rate policy. It shows that optimal policy when only a single policy tool is available is a tax before and a subsidy during the crisis. Furthermore, the tradable revenue policy over a borrowing-targeted policy provides higher welfare gains. Lastly, chapter 3 investigates the role of financial frictions on technological adoption and macroeconomic implications. It develops a model with heterogeneous producers, different productivity and wealth levels, and studies the implications of financial development on technology adoption rates. This chapter emphasizes how the inclusion of the intermediate technology helps replicate key features observed in micro-level data and provides positive effects of intermediate technology on macroeconomic variables such as consumption, output, and TFP. Overall, this dissertation uses theoretical and empirical approaches to provide essential policy implications for policymakers in emerging and developing economies. The findings contribute to the ongoing discussion on how financing opportunities play a role through investment and technological adoption channels to cause financial instability and subsequent policy implementations.

description: We present fVDB, a novel GPU-optimized framework for deep learning on large-scale 3D data. fVDB provides a complete set of differentiable primitives to build deep learning architectures for common tasks in 3D learning such as convolution, pooling, attention, ray-tracing, meshing, etc.
 fVDB simultaneously provides a much larger feature set (primitives and operators) than established frameworks with no loss in efficiency: our operators match or exceed the performance of other frameworks with narrower scope. Furthermore, fVDB can process datasets with much larger footprint and spatial resolution than prior works, while providing a competitive memory footprint on small inputs. To achieve this combination of versatility and performance, fVDB relies on a single novel VDB index grid acceleration structure paired with several key innovations including GPU accelerated sparse grid construction, convolution using tensorcores, fast ray tracing kernels using a Hierarchical Digital Differential Analyzer algorithm (HDDA), and jagged tensors.
 Our framework is fully integrated with PyTorch enabling interoperability with existing pipelines, and we demonstrate its effectiveness on a number of representative tasks such as large-scale point-cloud segmentation, high resolution 3D generative modeling, unbounded scale Neural Radiance Fields, and large-scale point cloud reconstruction.

description: Opinion Dynamics is an interdisciplinary area of research. Psychology and Sociology have proposed models of how individuals form opinions and how social interactions influence this process. Socio-Physicists have interpreted patterns in opinion formation as arising from non-linearity in the underlying process, shaping the models. Agent-based modeling has offered a platform to study the Opinion Dynamics of large groups. This paper recasts recent models in opinion formation into a proper dynamical system, injecting the idea of clock time into evolving opinions. The time interval between successive receipts of new information (frequency of information receipts) becomes a factor to study. Social media has shrunk time intervals between information receipts, increasing their frequency. The recast models show that shorter intervals and larger networks increase an individual's propensity for polarization, defined as an inability to hold a neutral opinion. A Polarization number based on sociological parameters is proposed, with critical values beyond which individuals are prone to polarization, depending on psychological parameters. Reduced time intervals and larger interacting groups can push the Polarization number to critical values, contributing to polarization. The Extent of Polarization is defined as the width of the region around neutral within which an individual cannot hold an opinion. Results are reported for model parameters found in the literature. The findings offer an opportunity to adjust model parameters to align with empirical evidence, aiding the study of Opinion Dynamics in large social networks using Agent-Based Modeling.

OPTIMISATION OF THE INDUCTIVELY-COUPLED PLASMA FOR THE ANALYSIS OF SOLUTIONS AND SLURRIES
Creators: name: NORMAN, PHILIP
Publisher: name: University of Plymouth
Year: 1987

description: The application of inductively-coupled plasma (ICP) spectrometry for the analysis of solutions and slurries is reviewed. The critical parameters which affect analytical performance are identified and methods for the optimisation of the ICP for such applications demonstrated. Particle size of the suspended sample is shown to be the most important factor in the analysis of slurry samples. It is demonstrated that only particles less than 8 um in diameter reach the plasma even when the maximal diameter injector tube (3 mm i.d.) is used. Accordingly various methods for the reduction of particle size have been investigated and milling shown to be the preferable approach. A low cost method using blown zirconia spheres in a screw-cap plastic bottle agitated on a flask shaker was developed. Using this method it proved possible to analyse a wide variety of solid samples using slurry atomisation using both ICP- atomic emission spectrometry (ICP-AES) and ICP-mass spectrometry (ICP-MS) with aqueous calibration. Results are presented for the elemental analysis of certified reference material (CRM) soils, catalyst samples, a zeolite, titanium dioxide, P.T.F.E. powder, and unfiltered natural waters by slurry atomisation ICP-AES. Comparison by other techniques showed excellent accuracy for major, minor and trace elements and equivalent precision to solution analysis. The CRM soils, catalysts and the zeolite were also analysed by ICP-MS using slurry atomisation with similar success and enhanced accuracy at the trace level. Aluminium proved to be an exception and generally low recoveries (80-90%) were observed for this element using slurry atomisation. Finally the uses of the simplex optimisation algorithm to improve analytical performance, particularly in ICP-AES, is discussed. A computer program to facilitate the use of simplex optimisation for a variety of instrumentation was written and its use in three different analytical techniques demonstrated. The necessary hardware and software modifications to a commercially available ICP spectrometer to enable automated simplex optimisation are described. The prospects for such intelligent self-optimising instrumentation are discussed as is the potential extension of the application of slurry analysis by ICP-AES and ICP-MS.
DEVELOPMENT AND INVESTIGATION OF THE PROPERTIES OF AN ELECTROCHEMICALLY REGENERABLE CHEMICALLY MODIFIED ELECTRODE FOR CHEMELUMINESCENCE DETECTION OF ANALYTES IN SOLUTION

description: The aim of this study was to exploit the sensitivity of the chemiluminescent ruthenium tris(2,2'-bipyridme) redox system for analytical purposes by producing electrochemically regenerable electrodes modified with a polymer derivative of this complex. Ruthenium tris(4-meth}i-4' -vinyl-2,2' -bipyridine) bis(hexafluorophosphate) was synthesised and subsequently polymerised onto an electrode surface using the technique of cyclic voltammetry. A potential was applied to the resulting Chemically Modified Electrode (CME) and upon reaction of the ruthenium centres with an analyte in solution, chemiluminescence was observed. Measurement of the emission intensity was used for the determination of the analyte concentration The ruthenium centres were subsequently regenerated by the reversal of the applied potential Very littie environmentally unfriendly and expensive waste results from this process. This is in direct contrast with current methods which traditionally use the ruthenium tris(2,2'-bipyndine) complex either in solution or immobilised within a membrane for analyses of this type. Attention was focused upon detection of the oxalate ion and the ruthenium tris(2,2'-bipyridine)/oxalate redox system reported in the literature was used as a model to investigate the capabilities of the CME's produced. A scan rate of 10 V/s between the potential limits of + 0.5 to + 1.5 V at pH 6.5 was established as the optimum conditions. A linear working range for oxalate was observed from 1.9 x 10'^ M to the limit of detection, 1.1 x 10'^ M. The lifetime of a CME was investigated and although the chemiluminescent signal diminished with time, the electrode was still functioning after 24 weeks, a total of over 200 regenerations. A series of amines and valine were also successfully detected using CME's. In addition, a similar sensor was fabricated from the electropolymerization of a novel ruthenium complex, ruthenium tris(4-methyl-4'-(£-prop-2-enyl>2,2'-bipyridine) bis(hexafluorophosphate). This was also shown to be capable of chemiluminescence emission and was successfully regenerated Two electrochemically regenerable CME's were therefore produced and this research is a valuable advance in the field of chenuluminescent detectors.
