Sediment Heterogeneity and Sand Production in Gas Hydrate Extraction: Daini-Atsumi Knoll, Nankai Trough, Japan

description: The possibility of commercial natural gas production from gas hydrates has been tested by researchers and industry for more than ten years. Depressurisation of gas hydrates in porous and permeable sandstones has successfully produced water and natural gas. However long term sustainable production is still elusive. Catastrophic sand production into the wellbore has terminated at least three of the significant depressurisation trials including the 2013 trial at the Daini-Atsumi knoll, Nankai Trough, offshore Japan. Sand production is generally thought to be the result of mechanical and hydrodynamic instability, however it appears the failure mechanism is not the same for all reservoirs and the location of reservoir porosity and pressure on the normal compression line for sands could be a controlling factor. Sand production in reservoirs at shallow depths and low confining stresses (less than 10 MPa) are likely to be influenced by fluid flow effects like those described by the Shields (1936) diagram. The relative density of the formation may also affect the nature of the sand production in these reservoirs. The Daini-Atsumi knoll is a structural high on the outer ridge of the Kumano forearc basin, offshore Japan. Hydrate saturations of 50 to 80 % occur within three geological units of the Middle Pleistocene Ogasa group. This group is made up of deep water sediments including sediment gravity flow deposits distinguished by alternating silt and sand layers. The presence of these alternating layers could have influenced the sand production seen during the trial. This reservoir heterogeneity at the 2013 Daini-Atsumi knoll gas hydrate production trial site was characterised using the descriptions of geological units, analogues and statistical techniques. Scenarios of this heterogeneity were tested in a high pressure plane-strain sand production apparatus. The results of these tests suggest the boundary shear stress of the fluid on the grains is a significant control on sand production for the Daini-Atsumi Knoll reservoir and the layering and grainsize structure of the sediments encourages sand production. Relative density of the sediments appears to impact the nature of the sand production where denser sediments show more localised movement. These results indicate that even minor weaknesses in sand control devices will result in uncontrollable sand production rates from the Daini-Atsumi Knoll gas hydrate reservoir. Managing the fluid flow rate in the reservoir and selectively completing coarser grained zones at the base of sand layers could help limit sand production in future trials.

description: Functionally graded material (FGM) is a class of advanced materials, consisting of two (or more) different constituents, that possesses a continuously varying composition profile. With the advancement of nanotechnology, applications of FGMs have shifted from their conventional usage towards sophisticated micro and nanoscale electronics and energy conversion devices. Therefore, the study of mechanical and vibrational properties of different FGM nanostructures is crucial in exploring their feasibility for different applications. In this study, for the first time, we employed molecular dynamics (MD) simulations to investigate the mechanical and vibrational properties of radially graded Cu-Ni FGM nanowires (NW). Distribution of Cu and Ni along the radial direction follows power-law, exponential and sigmoid functions for FGM NWs under consideration. Our results demonstrate that, distribution function parameters play an important role in modulating the mechanical (elastic modulus and ultimate tensile strength) and vibrational (natural frequency and quality factor) properties of FGM NWs. The study also suggests that, elastic moduli of FGM NWs can be predicted with relatively good accuracy using Tamura and Reuss micromechanical models, regardless of NW diameter. We found that, Euler-Bernoulli beam theory under-predicts the natural frequencies of FGM NWs, whereas He-Lilley model closely approximates the MD results. Interestingly, FGM NWs are always found to exhibit beat vibration because of their asymmetrical cross sections. Finally, this is the first atomistic scale study of FGMs that directly compares MD simulations with continuum theories and micromechanical models to understand the underlying mechanisms that govern the mechanical and vibrational properties of FGM NWs in nanoscale.

description: This paper investigates farm technical efficiency (TE), taking into account technological heterogeneity among farms in the case of the Slovenian Farm Accountancy Data Network sample of farms in the 2007-2010 period. A random parameter model is used to analyse inter- and intra-sectoral heterogeneity of farms. The empirical results confirmed that it is important to handle both inter- and intra-sectoral heterogeneity. Additionally the estimations based on propensity score matching (PSM) demonstrated that farms in less favoured areas (LFAs) are slightly technically less efficient than farms in non-LFAs. However, combined PSM and difference in difference estimator cast serious doubts that LFA farms are less efficient in terms of TE. Both groups of farms are able to adopt technologies to natural and other conditions for their operation.

description: In this contribution I will review the analysis of the Einstein-Podolsky-Rosen argument, Bell's inequalities and of associated experiments for spins in terms of positive operator valued measures. Specifically, I will explore the relation between the Clauser-Horne-Shimony-Holt inequality and a fundamental \emph{classicality} property of observables -- their \emph{coexistence}. A derivation of Bell's inequalities for unsharp spins will be given which follows a reconstruction by Mittelstaedt and Stachow of the original EPR argument. In this context we discuss the need for a consistent relativistic description of localised measurements, carried out in spacelike separated regions of spacetime on spatially extended, entangled systems.

description: This thesis investigates the role and identity of manorial officers, individuals drawn from a lord’s tenants who were vital in administering his manor court and directly-farmed lands. It analyses officeholding from a social and political standpoint, examining the role of officers in governing village communities, and how this was affected by the decline of lordship and development of the state. The study deliberated bridges the medieval/early modern divide, analysing the period 1300-1600. The evidence base for this investigation relies on the reconstruction of officeholding from the court rolls of three case-study manors. These consist of Little Downham (Cambs.), Horstead (Norf.) and Worfield (Salop.). The first part of the thesis utilises quantitative methodologies to analyse the change in presentments made by officers (chapter one) and patterns in participation in office (chapter two). The second part adopts a qualitative approach to examine the role of officers in governing village communities (chapter three), attitudes to office among manorial tenants (chapter four), and the interaction of officeholding with the state and especially with the emergent civil parish (chapter five). Four central conclusions emerge from this work. Firstly, manorial officeholding remained an important institution in the English countryside across the period 1300-1600. Secondly, this was achieved via support from tenants who were invested in manorial office rather than pressure from lords or the crown. Thirdly, officeholding worked to create and reinforce social stratification, helping maintain the position of a village elite. Fourthly, the officeholding system was robust enough to survive the expansion of the state into local communities under successive English monarchs. These conclusions in turn have implications for the wider historical literature concerning late medieval and early modern England. They reinforce the revisionist argument that lord-tenant relations were not inevitability hostile and that many wealthier tenants benefitted from seignorial structures. More significantly, they add weight to the notion of a medieval equivalent to the early modern ‘middling sort’, suggesting that the emergence of a local elite was operative through manorial structures long before 1600.

Derivation of the Mass Distribution of Extrasolar Planets with MAXLIMA - a Maximum Likelihood Algorithm

Year: 2001

description: We construct a maximum-likelihood algorithm - MAXLIMA, to derive the mass distribution of the extrasolar planets when only the minimum masses are observed. The algorithm derives the distribution by solving a numerically stable set of equations, and does not need any iteration or smoothing. Based on 50 minimum masses, MAXLIMA yields a distribution which is approximately flat in log M, and might rise slightly towards lower masses. The frequency drops off very sharply when going to masses higher than 10 Jupiter masses, although we suspect there is still a higher mass tail that extends up to probably 20 Jupiter masses. We estimate that 5% of the G stars in the solar neighborhood have planets in the range of 1-10 Jupiter masses with periods shorter than 1500 days. For comparison we present the mass distribution of stellar companions in the range of 100--1000 Jupiter masses, which is also approximately flat in log M. The two populations are separated by the "brown-dwarf desert", a fact that strongly supports the idea that these are two distinct populations. Accepting this definite separation, we point out the conundrum concerning the similarities between the period, eccentricity and even mass distribution of the two populations.

description: Fluorophores are a class of chemical compound that can absorb light of a certain wavelength and emit light at a longer wavelength upon de-excitation. Their applications include chemosensing and immunofluorescence with a move towards the near infrared (NIR) light region allowing for safe in vivo applications. This work presents the further expansion of the numerous applications of the BF2- tetraarylazadipyrromethene (NIR-AZA) class of fluorophores with fluorescence in the NIR region (700–1100 nm). Novel NIR-AZAs have been designed, synthesised and tested resulting in peer reviewed publications. In Chapter 2, a novel bis-pegylated NIR-AZA 12 was successfully employed in intraoperative NIR fluorescence guided ureter identification at 720 nm in rodent and porcine models. The concept of passive targeting using an “always on” fluorophore was exploited with visualisation of the ureter achieved 20 minutes post?administration. 12 was found to be non-toxic in a pre-clinical rodent toxicity study and was successfully imaged in tandem with clinically approved ICG, presenting its potential use in multi-channel intraoperative NIR imaging. In Chapter 3, a targeted probe was designed with applications including NIR fluorescence guided tumour identification and excision. A photoinduced electron transfer quenching mechanism was exploited in fluorogenic bioorthogonal chemistry. A novel bis(aryloxy) 1,2,4,5-tetrazine 2 was synthesised in order to predict the reactivity of the bioorthogonal bicyclononyne (BCN) and methyl cyclopropene (MCp) moieties towards a fluorogenic NIR-AZA 1. BCN was identified as the preferred reacting partner. A fluorescence turn-on bioorthogonal reaction was achieved with BCN-glucose mimic 5 and Tz-NIR-AZA 1 in live-cells allowing for CLSM imaging at 720 nm. In Chapter 4, four novel fluorescent probes were designed to bridge the availability gap of fluorescent probes for live-cell confocal microscopy at 800–850 nm. The internal charge transfer mechanism was exploited in order to red-shift the emission by ~100 nm relative to those NIR-AZAs in Chapters 2 and 3. Their molecular design included the placement of solubilising groups on the fluorophore scaffold to guide their subcellular localisation and NIR imaging of live-cells at 800–850 nm was achieved.

description: Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting quantum spin models. Effective spins are represented by appropriate internal energy levels within each ion, and the spins can be measured with near-perfect efficiency using state-dependent fluorescence techniques. By applying optical fields that exert optical dipole forces on the ions, their Coulomb interaction can be modulated to produce long-range and tunable spin-spin interactions that can be reconfigured by shaping the spectrum and pattern of the laser fields, in a prototypical example of a quantum simulator. Here we review the theoretical mapping of atomic ions to interacting spin systems, the preparation of complex equilibrium states, the study of dynamical processes in these many-body interacting quantum systems, and the use of this platform for optimization and other tasks. The use of such quantum simulators for studying spin models may inform our understanding of exotic quantum materials and shed light on the behavior of interacting quantum systems that cannot be modeled with conventional computers.

We demonstrate that a fast colored noise much weaker than the conventional white noise can produce transitions itself or can change substantially the Landau-Zener transition probabilities. In the limit of fast colored or strong white noise we derive asymptotically exact formulae for transition probabilities and study the time evolution of a spin coupled to the noise and a sweeping magnetic field.

description: Demography is a major determinant of the variation of species. Understanding how it effects the genetic composition of populations allows us to infer history from genetic data. I contribute to this project in three ways. First, I estimate the historical trajectories of effective population size in Pan and Pongo. These analyses are based on past rates of coalescence, estimated within and between populations, and they use the largest known samples of whole genomes for each species. From these, I infer new histories of migration and separation in each genus. Second, the interpretation of past rates of coalescence is known to depend on whether a population is structured. I analyse a novel model of non-equilibrium island structure and propose an approach through which it can be used to aid the interpretation of estimated historical changes in effective population size. This is based on comparisons of the effects on theoretical distributions of coalescent times. The approach is then applied to examples arising in chimpanzee and human population history, in both cases suggesting effective population size changes are more likely due to changes in census population size, rather than island structure. The proliferation of ancient DNA sequencing presents a rich new resource. I develop a haplotype-based approach to help test more directly for ancestral structure. It is based on reconstructions of the ancestral recombination graph of a sample. The method incorporates an explicit coalescent analysis of locus ancestry under idealised demographic models. It jointly analyses samples of ancient and modern whole genomes in which modern sequences trace some recent part of their ancestry to populations from which the ancient sequences are drawn. I illustrate some of the possibilities and limitations of this tentative approach and apply it to questions about the peopling of North America.

description: Coronal jets are observed above minority polarity intrusions throughout the solar corona. Some of the most energetic occur on the periphery of active regions where the magnetic field is strongly inclined. These jets exhibit a non-radial propagation in the low corona as they follow the inclined field, and often have a broad, helical shape. We present a three-dimensional magnetohydrodynamic simulation of such an active-region-periphery helical jet. We consider an initially potential field with a bipolar flux distribution embedded in a highly inclined magnetic field, representative of the field nearby an active region. The flux of the minority polarity sits below a bald-patch separatrix initially. Surface motions are used to inject free energy into the closed field beneath the separatrix, forming a sigmoidal flux rope which eventually erupts producing a helical jet. We find that a null point replaces the bald patch early in the evolution and that the eruption results from a combination of magnetic breakout and an ideal kinking of the erupting flux rope. We discuss how the two mechanisms are coupled, and compare our results with previous simulations of coronal-hole jets. This comparison supports the hypothesis that the generic mechanism for all coronal jets is a coupling between breakout reconnection and an ideal instability. We further show that our results are in good qualitative and quantitative agreement with observations of active-region periphery jets.

description: Following the idea of nucleon clustering and light-nuclei production in relativistic heavy-ion collisions close to the QCD critical-end point, we address the quantum effects affecting the interaction of several nucleons at finite temperature. For this aim we use the $K$-harmonics method to four-nucleon states ($α$ particle), and also develop a novel semiclassical "flucton" method at finite temperature, based on certain classical paths in Euclidean time, and apply it to two- and four-particle configurations. To study possible effects on the light-nuclei production close to the QCD critical point, we also made such calculations with modified internuclear potentials. For heavy-ion experiments, we propose new measurements of light-nuclei multiplicity ratios which may show enhancements due to baryon preclustering. We point out the special role of the $\mathcal{O}(50)$ four-nucleon excitations of $α$-particle, feeding into the final multiplicities of $d,t$, $^3$He and $^4$He, and propose to directly look for their two-body decays.

description: We measure the galaxy luminosity function (LF) for the Virgo Cluster between blue magnitudes M_B = -22 and M_B = -11 from wide-field CCD imaging data. The LF is only gradually rising for -22 < M_B < -16. Between M_B = -16 and M_B = -14 it rises steeply, with a logarithmic slope alpha ~ -1.6. Fainter than M_B = -14, the LF flattens again. This LF is shallower (although turning up at brighter absolute magnitudes) than the R-band LF recently measured by Phillipps et al. (1998), who found alpha ~ -2.2 fainter than M_R = -13. It is similar, however, to the LF determined from the Virgo Cluster Catalog by Sandage et al. (1985). A few faint galaxies are found which Sandage, et al. missed because their surface-brightness threshold for detection was too high, but these do not dominate the luminosity function at any magnitude. Most of the faint galaxies we find are dwarf elliptical, alternatively called dwarf spheroidal, galaxies. The most important potential source of systematic error is that we may have rejected some high surface-brightness galaxies from the cluster sample because we think that they are background galaxies. This is quite different from what has conventionally been regarded as the most serious source of systematic error in this kind of study: that we are missing many LOW surface-brightness galaxies because they are never visible above the sky.

description: Over the last years Turkey has been increasingly associated in the international political and economic debate with concepts such as “gas corridor” and “gas hub”. This characterization of Turkey is clearly mainly due to its unique geographical position at the crossroads the Caspian region, the Middle East and Europe. In particular, this argument is often advanced in the political discussion on the rise of Turkey as a leading regional power and in the debate on the future prospects for the EU-Turkey relations. However, by going beyond the political slogans and by focusing on the concrete gas realities around Turkey this picture could be seriously put into question. The aim of this paper is to explore the real potential role of Turkey in the regional gas markets, firstly focusing on the current situation of gas producing countries around Turkey and then moving to the future prospects of gas cooperation in the region. To this end, the paper will provide an assessment of both the current situation and outlook of gas markets in Azerbaijan, Turkmenistan, Iraq, Iran, Israel and Cyprus, subsequently providing a discussion of the future prospects of the Southern Gas Corridor and of the potential Eastern Mediterranean Gas Corridor. This analysis will indicate that Turkey will hardly have the potential to become a regional gas hub in the medium term (up to 2020-2025). However, Turkey could have the potential to play an important role in the regional gas markets in the longer term (after 2025-2030) if a number of infrastructural, commercial and political barriers described in the paper are overcome and -last but not the least- if the EU gas demand recovers and the EU market actually needs more natural gas supplies.
Tangency property and prior-saturation points in minimal time problems in the plane

description: In this paper, we consider minimal time problems governed by control-affine-systems in the plane, and we focus on the synthesis problem in presence of a singular locus that involves a saturation point for the singular control. After giving sufficient conditions on the data ensuring occurence of a prior-saturation point and a switching curve, we show that the bridge (i.e., the optimal bang arc issued from the singular locus at this point) is tangent to the switching curve at the prior-saturation point. This property is proved using the Pontryagin Maximum Principle that also provides a set of non-linear equations that can be used to compute the prior-saturation point. These issues are illustrated on a fed-batch model in bioprocesses and on a Magnetic Resonance Imaging (MRI) model for which minimal time syntheses for the point-to-point problem are discussed.

Self-interacting dark matter from an SU(3)_L \otimes U(1)_N electroweak model

description: Recently has been showed that models which consider self-interacting particles as dark matter candidates can be able to account all the discrepancies between N-body simulations and astronomical observations of the galactic structure. In the present work we show that the 3-3-1-electroweak model can provide a realistic candidate to this kind of dark matter. This dark matter particle is not arbitrarily imposed and no new symmetry is need for to stabilize it.

Proton acceleration in pulsar magnetospheres

description: Pulsars have been identified as good candidates for the acceleration of cosmic rays, up to ultra-high energies. However, a precise description of the acceleration processes at play is still to be established. Using 2D particle-in-cell simulations, we study proton acceleration in axisymmetric pulsar magnetospheres. Protons and electrons are extracted from the neutron star surface by the strong electric field induced by the rotation of the star, and electrons and positrons are produced in the magnetosphere through pair production process. As pair production has a crucial impact on electromagnetic fields, on gaps and thus on particle acceleration, we study its influence on the maximum energy and luminosity of protons escaping the magnetosphere. Protons are accelerated and escape in all our simulations. However, the acceleration sites are different for the protons and the pairs. As shown in previous studies, pairs are accelerated to their highest energies at the Y-point and in the equatorial current sheet, where magnetic reconnection plays and important role. In contrast, protons gain most of their kinetic energy below the light-cylinder radius within the separatrix current layers, but they are not confined within the equatorial current sheet. Their maximum Lorentz factors can reach $15\%$ to $75\%$ of the maximum Lorentz factor obtained by acceleration through the full vacuum potential drop from pole to equator, and increase with decreasing pair production. Their luminosity can reach $0.2\%$ to $4\%$ of the theoretical spin down luminosity of an aligned pulsar, and the minimum luminosity is obtained at the transition between the force-free and electrosphere regimes. These estimates support that millisecond pulsars could accelerate cosmic rays up to PeV energies and that new born millisecond pulsars could accelerate cosmic rays up to ultra-high energies.

description: This thesis is concerned with early Greek literary history and the nature of archaic Greek allusion. It examines how our earliest Greek poets self-consciously marked and signalled their interactions with other texts and traditions, often in a deeply antagonistic fashion. In recent years, scholars have explored how Roman poets signposted references to their predecessors through a range of relational metaphors, representing their allusions as acts of recollection, echo and theft. Yet although these readings have proved a popular and rewarding interpretative approach, such allusive phenomena are often assumed to be the preserve of the scholarly, literate and bookish climates of the Hellenistic and Roman worlds. In this study, by contrast, I highlight how these very same devices can already be detected in Archaic Greek Poetry, from Homer to Pindar, challenging any simple dichotomy between the orality of Archaic Greece and the literacy of Hellenistic Rome. After an introduction in which I lay out the objectives of my study and address the methodological difficulties of discussing allusion and intertextuality in early Greek poetry, the majority of the thesis is divided into three main sections, each of which addresses a different ‘index’ (marker/pointer) of allusion in archaic Greek epic and lyric. The first addresses what Latinists call the ‘Alexandrian footnote’: vague references to hearsay and anonymous tradition which frequently conceal specific nods to precise literary predecessors. The second focuses on poetic memory, exploring how characters’ reminiscences of events from their fictional pasts coincide with recollections of earlier literary texts and traditions. The final chapter turns to time and temporality, to explore how Greek poets both evoke and pointedly replay episodes of the literary past or future beyond their immediate narrative. Together, these three case studies demonstrate that the indexing and signposting of allusions was nothing new by the time of the Hellenistic age. What are sometimes considered distinctively learned flourishes of self-consciousness were in fact, I contend, an integral part of the literary tradition from the very start, a key feature of the grammar of allusion with which ancient audiences were already intuitively familiar.

description: Primordial non-Gaussianity signatures of extremely heavy particles are re-examined within a simple alternative to the standard inflationary paradigm, in which the primordial fluctuations and the inflationary spacetime expansion are sourced by two different fields. The curvaton scenario provides an example of this in which the distinct roles are played by the curvaton and the inflaton fields, respectively. We study couplings of the curvaton to heavy particles with masses of order the inflationary Hubble scale, and show that they can lead to non-Gaussian signals orders of magnitude larger than those in standard inflation, consistent with explicit effective field theory control of inflationary dynamics. This brings various motivated particle physics signatures, such as loops of heavy gauge-charged scalars and fermions, within future observational reach.

description: We present NIR observations of a sample of mainly interacting ULIRGs, comprising H and K band spectra. Our main aims are to investigate the power source of these extremely luminous objects and the various excitation mechanisms of the strong molecular hydrogen emission often seen in such objects. Broadened emission lines were only detected in one object, IRAS 23498, consistent with previous results for this galaxy. The [SiVI] emission line was detected in IRAS17179 and IRAS20210, both classified as Sy2s. Two of the sample were unclassified, IRAS00150 and IRAS23420, which exhibit neither [SiVI] emission or broadened HI emission. However this does not rule out the presence of an obscured AGN. Analysis of the molecular hydrogen emission showed that the major excitation mechanism for most objects was thermal. Modelling of the more luminous objects indicate for IRAS20210 10 per cent, and for both IRAS23365 and IRAS23420, 30 per cent of their 1-0S(1) line emission has a non-thermal origin.
