Life and death in the Korean Bronze Age (ca. 1500 – 400 BC): an analysis of settlements and monuments in the mid-Korean peninsula

This thesis focuses on the Bronze Age in selected areas of Korea; Seoul, Incheon, and Gyeonggi province. Two forms of evidence - settlements and monuments - are taken into account to identify their relationship with landscape and the social changes occurring between ca. 1500 to 400 cal BC. Life and death in the Bronze Age in Korea has not been synthetically investigated before, due to the lack of evidence from settlements. However, since academic and rescue excavations have increased, it is now possible to examine the relationship between settlements and monuments on a broad scale and over a long-term sequence, although there are still limitations in the archaeological evidence. The results of GIS (Geographical Information Systems) analysis and Bayesian modelling of the radiocarbon dates from this region can be interpreted as suggesting that Bronze Age people in the mid-Korean peninsula had certain preferences for their habitation and mortuary places. The locations of two archaeological sites were identified and statistical significance was generated for their positioning on soil that was associated with agriculture. It was found that settlements tended to be located at a higher elevation with fine views and that monuments tended to be situated in the border zones between mountains and plains and also within the boundary of a 5km site catchment adjusted for energy expenditure, centring on each settlement. This configuration is reminiscent of the concept of the auspicious location, as set out in the traditional geomantic theory of Pungsu. It can be argued that Bronze Age people chose the place for the living and the dead with a holistic perspective and a metaphysical approach that placed human interaction with the natural world at the centre of their decision-making processes. These concepts were formed out of the process of a practical adaptation to the Bronze Age landscape and environment in order to practice agriculture as a subsistence economy, but they also exerted a profound influence upon later Korean peoples and their identities.

Redox-active rotaxanes and catenanes for anion sensing

This thesis is concerned with the synthesis and study of novel anion templated rotaxanes and catenanes for electrochemical anion sensing, as well as interlocked structures that possess different anion binding properties, higher-order topologies and the ability to undergo molecular motion.
Chapter One provides an introduction to anion recognition and the preparation of interlocked structures. A short summary of fundamental aspects of supramolecular chemistry is followed by detailed surveys of current approaches to anion binding and sensing, as well as the templated synthesis of rotaxanes and catenanes.
Chapter Two describes the preparation of rotaxanes and catenanes appended with ferrocene to allow for electrochemical anion sensing. The anion recognition properties of a [2]rotaxane and a [2]catenane, as investigated by ¹H NMR spectroscopy and electrochemical methods, are presented. The utilization of a ferrocene-appended macrocycle in the construction of surface confined anion templated rotaxanes and catenanes is also discussed.
Chapter Three reports the work carried out to achieve electrochemical anion sensing by the incorporation of redox-active groups into the integral structures of interlocked structures. The syntheses of a bis-stoppered 1, 2, 3, 4, 5-pentaphenylferrocene [2]rotaxane and a ferrocene containing [3]rotaxane are presented, along with their subsequent anion recognition studies. In addition, attempts to incorporate ferrocene into the macrocyclic components of rotaxanes and catenanes are outlined.
Chapter Four details further investigations into the use of interlocked structures to achieve anion recognition. Doubly-charged [2]catenanes able to bind anions in aqueous solvent media, as well as the incorporation of alternative anion binding motifs into interlocked architectures are reported. The exploitation of anion templated synthesis to allow for the construction of higher order structures (including [3]catenanes, a “handcuff” catenane and a Janus [2]rotaxane), as well as a [2]catenane system with anion controlled molecular motion is also described.
Chapter Five presents the experimental procedures and characterization data relating to the compounds prepared in Chapters Two, Three and Four.
Chapter Six summarizes the main conclusions of the work contained within this thesis.
Supplementary experimental information relating to titration protocols, investigations into self-assembled monolayers (SAMs) and crystallographic data are provided in Appendices I, II and III.

The impact of intraguild competition with lion Panthera leo on leopard Panthera pardus behavioural ecology

Single-species research dominates the field of ecology; however there is a growing appreciation of the importance of a multi-species approach to holistic conservation. Carnivores exert a top-down control on other species, and are vital components of stable ecosystem functioning. Physiologically adapted for predation upon other animals, competition between carnivores can be particularly aggressive; frequently resulting in mortality, and even population suppression. Big cat research has historically focused on those species that are most easily observable; in particular the lion Panthera leo. The majority of the Felidae however are secretive and elusive, and receive relatively little scientific attention. In particular, there are few data available that measure the effect of direct intraguild interactions between carnivores. Using leopards Panthera pardus as a model species, this research aimed to investigate the impact of lions on the behavioural ecology of a socially subordinate carnivore. Leopards are the most abundant large carnivore in Africa, and have the largest global range of all felids; their ecological niche overlapping with that of both lions and tigers. The knowledge gained from examining their competitive interactions is therefore widely relevant, and may be applicable to other subordinate carnivore species that remain unstudied. Biotelemetry and camera-trap data were modelled using novel algorithms to show that lions impact on leopard population density, demographics and spatial ecology. Faecal analyses suggest that dietary niche segregation may facilitate sympatry. These results indicate the level of impact that large carnivores can exert over smaller species, and the potential for a focus on single-species conservation to undermine holistic conservation. The manifestation of intraguild competition has a significant influence on an animal’s ecology; leopards are generalist species that cope with persecution by adapting their behaviour and niche. Ecological specialists may not fare as well under competitive pressure, and proactive conservation initiatives may be required for endangered species.

The role of the complete Coriolis force in cross-equatorial transport of abyssal ocean currents

In studies of the ocean it has become conventional to retain only the component of the Coriolis force associated with the radial component of the Earth’s rotation vector, the so-called “traditional approximation”. We investigate the role of the “non-traditional” component of the Coriolis force, corresponding to the non-radial component of the rotation vector, in transporting abyssal waters across the equator.
We first derive a non-traditional generalisation of the multi-layer shallow water equations, which describe the flow of multiple superposed layers of inviscid, incompressible fluid with constant densities over prescribed topography in a rotating frame. We derive these equations both by averaging the three-dimensional governing equations over each layer, and via Hamilton’s principle. The latter derivation guarantees that conservation laws for mass, momentum, energy and potential vorticity are preserved. Within geophysically realistic parameters, including the complete Coriolis force modifies the domain of hyperbolicity of the multi-layer equations by no more than 5%. By contrast, long linear plane waves exhibit dramatic structural changes due to reconnection of the surface and internal wave modes in the long-wave limit.
We use our non-traditional shallow water equations as an idealised model of an abyssal current flowing beneath a less dense upper ocean. We focus on the Antarctic Bottom Water, which crosses the equator in the western Atlantic ocean, where the bathymetry forms an almost-westward channel. Cross-equatorial flow is strongly constrained by potential vorticity conservation, which requires fluid to acquire a large relative vorticity in order to move between hemispheres. Including the complete Coriolis force accounts for the fact that fluid crossing the equator in an eastward/westward channel experiences a smaller change in angular momentum, and therefore acquires less relative vorticity. Our analytical and numerical solutions for shallow water flow over idealised channel topography show that the non-traditional component of the Coriolis force facilitates cross-equatorial flow through an almost-westward channel.

Round temples in Roman architecture of the Republic through the late Imperial period

Roman round temples are usually discussed either in the context of round buildings like baths and mausolea or on a case-by-case basis. Both approaches fail to reveal what makes round temples a distinct architectural type and moreover, what reasons can account for their use throughout the Roman world. By examining round temples from the Republic, when they are first attested, to the early fourth century AD, this thesis aims to explain why the round form had such a lasting appeal. It follows a chronological approach, discussing the evidence for individual temples and situating them within their historical, social, topographical, and architectural contexts. In a comparative analysis, the building components, materials, techniques, decorative details, and proportions employed by round temples are outlined to reveal influences on their design. The round temples discussed in this study are concentrated in Italy, Greece, and Asia Minor. While the earliest examples in Rome draw on Italic traditions, from the late Republic, round temples begin to reflect Greek trends. Greek tholoi and the Greek decorative repertory, balanced by Roman developments in design, have a lasting influence on round temples. Based on tholoi, scholars have assumed that Roman round temples honored Vesta and divinized heroes. While they were celebrated with a few examples, the majority were dedicated to other gods and goddesses. As a result, religious, social, topographical and aesthetic reasons are proposed to explain the enduring appeal of round temples. Like the motivations behind their foundations, the plans, dimensions, and proportional relationships employed by round temples are noted for their diversity. For their individuality and inventive spirit, round temples make a significant contribution to the Roman architectural repertory.

Autoantibodies to N-methyl D-aspartate receptors in autoimmune encephalitis

N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis is a recently described autoimmune encephalopathy defined by the presence of serum antibodies that bind NMDARs (NMDAR-Abs). NMDAR-Ab encephalitis is a severe, but treatmentresponsive encephalitis with subacute onset. It can be associated with tumours and affects mainly young adults. Patients present with cognitive dysfunction, seizures, psychiatric and sleep disorders and most develop dyskinesias, autonomic instability and reduced consciousness. To explore further the NMDAR-Abs and their potential pathogenicity, a series of in vitro investigations were performed and preliminary attempts at passive transfer of disease. Human embryonic kidney (HEK) cells transfected with the NR1 and NR2B subunits, and live cultured neurons, were used first to detect NMDAR-Ab binding. Immunocytochemistry and ow cytometry demonstrated that binding to transfected HEK cells could be improved when NMDAR were presented in clusters by cotransfection with the postsynaptic density protein PSD-95. The NR1 subunit was identified as the target of NMDAR-Abs, and a novel quantitative assay based on immunoprecipitation of NR1 tagged by fusion with green uorescent protein was developed. Measurement of NMDAR-Ab levels showed that antibody levels corresponded to the clinical disease score within individual patients. Although the purification of full length NR1 was not successful, a secreted N-terminal construct was created and expressed in HEK cells. The binding of NMDAR-Abs was confirmed and this construct will be used for active immunisation in future. To explore pathogenic mechanisms in vitro, the main antibody subclasses were shown to be IgG1 and IgG3. Moreover the patients' autoantibodies, but not healthy control antibodies, were able to activate the complement cascade in vitro in cell lines and primary cultures. Finally, the NMDAR-Abs were shown to bind to primary microglial cultures and to cause morphological changes corresponding to early activation processes after prolonged exposure. The research has developed new assays that could be used for diagnosis and serial studies and revealed new potential mechanisms in NMDAR-Ab encephalitis.

A metathesis based approach to the synthesis of heteroaromatic compounds

The olefin metathesis reaction is a well established and powerful method for the synthesis of alkenes. This reaction can be further classified into the intermolecular process known as cross-metathesis and the intramolecular process known as ring-closing metathesis. The aim of these studies is the use of the two variants of the metathesis reaction for the development of new methods for the synthesis of heteroaromatic structures, in particular the synthesis of polysubstituted pyridines.

The existential dimension of the liberation theology of Juan Luis Segundo

Juan Luis Segundo (1925-1996) was a Uruguayan Jesuit priest who, I argue, based his liberation theology on his understanding of existentialism. The major contribution of this thesis is the exploration of unknown and unexplored sources in Segundo's work. These sources support my thesis of his basis in existentialism and are corroborated by his mature theology. This thesis is significant because the connection between existentialism and liberation theology has been widely overlooked. My starting point is Segundo's 1948 book, in which he combines existentialism with personalism and develops a transcendental method grounded in love and inter-subjectivity. The following three chapters develop my argument through his engagement with four existentialist thinkers: Berdyaev, Sartre and Camus, and Heidegger. Chapter 3 demonstrates how Segundo follows Berdyaev's primacy of freedom, which allows for human creativity, but Segundo takes it as a "quality of the will" and relates freedom to love. Berdyaev influences Segundo's preference for a methodology yielding consistent growth rather than a systematic approach to theology. Chapter 4 shows how Sartre's and Camus' understanding of freedom and limits influenced Segundo's sense that a person's lived reality must be the starting point for theological reflection (e.g. the hermeneutic circle). In chapter 5, I use an unpublished manuscript to show how Segundo uses the place of tradition in the Christian church and the role of tradition in Heidegger's phenomenological analysis of Dasein in order to build his theology of "liberative human seeking and divine revelation". In the final two chapters, I draw the new sources together with two of Segundo's widely read books: Faith and Ideologies (1982) in chapter 6 and The Liberation of Theology (1975) in chapter 7. In chapter 6, the transcendental method he first wrote about in 1948 returns and he addresses materialism and personalism. Chapter 7 serves as my conclusion and uses Segundo's hermeneutic circle as the fullest manifestation of my argument.

Distinct element modelling of jointed rock masses : algorithms and their verification

The distinct element method (DEM) is a useful tool in rock engineering to model jointed rock masses. To simulate a jointed rock mass realistically, the main challenge is to be able to capture its complex geometry which consists of blocks with various shapes and sizes, and to model the interactions between these blocks.
The main contribution of this thesis is the development of novel algorithms in the DEM to model jointed rock masses, namely rock slicing procedures for block generation, and algorithms for contact detection between polygonal blocks in 2-D or polyhedral blocks in 3-D. These algorithms make use of convex optimisation techniques, for which there exist efficient solution procedures. They do not rely on conventional vertex-edge-face hierarchical data structures and tedious housekeeping algorithms. The algorithms have been verified against analytical and numerical solutions, as well as validated against experimental results published in the literature. Among those, the results of DEM simulations were compared against the experimental model tests and numerical simulations of jointed beams carried out by Talesnick et al. (2007) and Tsesarsky & Talesnick (2007) respectively. Emphasis was placed on modelling the stiffness of the block interfaces accurately, and this was accomplished by reinterpreting the laboratory data published by the investigators.
The capabilities of the numerical tools are also examined and demonstrated in areas for which the DEM has found practical application. A substantial fraction of this thesis is devoted to illustrating how these tools can assist the engineer in designing support systems; for example, designing the length and spacing of rock bolts and the lining thickness for a tunnel. Algorithms to model rock bolt and lining support were implemented for this purpose. Interesting comparisons with elastic solutions for supported openings were obtained. Further, it is shown that the relative benefit of introducing more rock bolts or thicker lining can be evaluated using the numerical tools with the aid of an interaction diagram. In the final part of this thesis, the case history of the 1963 Vaiont rock slide in Italy is studied. The 2-D analyses led to useful insights concerning the influence of the reservoir water level, the rock mass strength and deformability, and the slide surface shear stiffness. 3-D analyses were undertaken to investigate the influence of the eastern boundary of the slope, and interesting insights were obtained concerning the slope kinematics. Overall, the case study shows that the tools are capable of modelling problems with specific physical and geometrical detail in both 2-D and 3-D.

The development of a methodology to approach carbon neutrality using temperate and tropical climates as case studies

The threat of climate change has become one of the major issues facing mankind over recent decades and its severity is escalating significantly with increased atmospheric greenhouse gas levels, due to the combustion of fossil fuels, exacerbating the situation. This study develops a methodology to design a renewable energy supply mix to meet demand.
Economic and environmental factors are included in the decision-making process in order to be consistent with the definition of sustainability set out by the United Nations. The economic criterion is represented by the total annual cost and the environmental criterion is represented by the emissions reduction. Analytical techniques are applied to assess the temporal, climatic and growth factors of demand. The supply mix is examined as the potential resource and available conversion technology components. Resources are statistically categorized by availability as determinative, dispatchable and stochastic. This study considers biomass as a dispatchable resource; solar as a determinative resource and wind as a stochastic resource. A constrained exhaustive search algorithm is adapted for supply mix design, including a search space minimization method for greater computational efficiency. The Lagrangian multipliers of cost and emissions reduction are calculated to determine the optimum supply mix.
In order to assess this methodology at different locations with temperate and tropical climates as well as dissimilar demand characters, it is implemented in two case studies attempting to achieve carbon neutrality. The first location is the island of Hanimaadhoo in the Republic of the Maldives. The island is classed as a poor wind regime, but high wind availability is apparent with low solar availability and so both resources have been examined as potentially complementing one another. The annual demand is 1.5 GWhe and can achieve carbon neutrality at a cost of $ 582,000 per year with a supply mix comprised of 1710 kWe PV and 6500 kWhe lead-acid battery storage. The second case study is the county of Oxfordshire in the UK and the Christ Church site, located within the county, as a model smaller-scale site. Oxfordshire has been examined under a land usage scenario that maximizes biomass establishment and 52 % emissions reduction can be achieved at a total annual cost of £ 182 million. A second scenario is examined that aims to create a net food import/export position in the county and allocates remaining land for biomass. This scenario can achieve a 76 % emissions reduction at a total annual cost of £ 169 million. The 60 % emissions reduction target set by Christ Church can be achieved with a 250 kWe energy crop Anaerobic digester and a 93 kWe PV array.
