The real and the ideal -- a study of Henry James's use of art objects and art imagery in the delineation of character.
Creators: name: Alder, Phyllis Kathleen
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to study Henry James's use of art objects and art imagery in the delineation of character. I have first endeavoured to briefly outline the basic concepts of art which James embraced and applied in his tales and novels, and have traced, in his literary and art criticism, his developing views of the "real," the "romantic," and the "ideal." James's change in attitude toward the "real" and the "romantic" has been noted in his own work published between 1876 and 1894, and the principal techniques of the painter which he employs have been set forth. In an analysis of three tales: "The Madonna of the Future," "The Liar," and "The Real Thing" I have attempted to illustrate James's view of the nature and function of art and the artist and the problems involved in achieving a satisfactory balance between the real and the ideal. The conclusions reached have been applied to two of James's major novels of his later phase: The Wings of the Dove and The Golden Bowl in an attempt to demonstrate that, using the objet d'art and art imagery (as in the stories examined), James achieves reality of characterization and the complete realization of the ideal in the real.

description: Excerpts from the report Foreword: This book contains a graphic digest of the results of the National Inventory of Soil and Water Conservation Needs. This Inventory has been a systematic on-the-ground study by the U.S. Department of Agriculture of the agricultural and other rural land of our country. All agencies of the Department concerned with land use, soil and water conservation, and management of land resources participated in it. The Soil Conservation Service had responsibility for leadership in conducting the Inventory. For 3 years, 1957-60, local people in every county jointly studied data from soil surveys of sample areas and related information from other sources to make the estimates summarized here. Altogether, more than 30,000 people in 3,000 counties participated. The results are unique in soil survey and land use statistics. This is the first time we have had consistent statistical sampling of the soil, slope, and erosion conditions and present land use in every county in the country. It is the first time that all creek-size watersheds have been delineated and their problems enumerated.

description: Preface: This is a revision and enlargement of "Agricultural Relief; a Selected List of References," compiled by Louise O. Bercaw and issued January 31, 1928. It includes the more important references on agricultural relief issued during the period from January, 1924, to May, 1929. No attempt has been made to include references to articles in farm journals except in a few cases where discussions of specific plans for relief were given. Brief annotations have been made for most of the entries to indicate the subject matter of the article. Special attention has been paid to the specific proposals for relief described in the various publications. In many cases, these notes have been quoted from, the articles themselves, but in a few instances quotations have been made from abstracts or reviews. The main part of the bibliography is arranged alphabetically and should be used in connection with the index.

description: Mit der ständig wachsenden Zahl von verteilten Cloudanwendungen und immer mehr Datenschutzverordnungen wächst das Interesse an legalen Cloudanwendungen. Jedoch ist vielen Betreibern der Legalitätsstatus ihrer Anwendung nicht bekannt. In 2018 wird die neue EU Datenschutzverordnung in Kraft treten. Diese Verordnung beinhaltet empfindliche Strafen für Datenschutzverletzungen. Einer der wichtigsten Faktoren für die Einhaltung der Datenschutzverordnung ist die Verarbeitung von Stammdaten von EU-Bürgern innerhalb der EU. Wir haben für diese Regelung eine Privacy Analyse entwickelt, formalisiert, implementiert und evaluiert. Außerdem haben wir mit iObserve Privacy ein System nach dem MAPE-Prinzip entwickelt, das automatisch Datenschutzverletzungen erkennt und ein alternatives, datenschutzkonformes Systemhosting errechnet. Zudem migriert iObserve Privacy die Cloudanwendung entsprechend dem alternativen Hosting automatisch. Hierdurch können wir eine rechtskonforme Verteilung der Cloudanwendung gewährleisten, ohne das System in seiner Tiefe zu analysieren oder zu verstehen. Jedoch benötigen wir die Closed World Assumption. Wir benutzen PerOpteryx für die Generierung von rechtskonformen, alternativen Hostings. Basierend auf diesem Hosting errechnen wir eine Sequenz von Adaptionsschritten zur Wiedererlangung der Rechtskonformität. Wenn Fehler auftreten, nutzen wir das Operator-in-the-loop Prinzip von iObserve. Als Datengrundlage nutzen wir das Palladio Component Model. In dieser Arbeit beschreiben wir detailliert die Konzepte, weisen auf Implementierungsdetails hin und evaluieren iObserve nach Präzision und Skalierbarkeit.

description: We study the Hardy-Littlewood maximal operator defined via an unconditional norm, acting on block decreasing functions. We show that the uncentered maximal operator maps block decreasing functions of special bounded variation to functions with integrable distributional derivatives, thus improving their regularity. In the special case of the maximal operator defined by the l_infty-norm, that is, by averaging over cubes, the result extends to block decreasing functions of bounded variation, not necessarily special.

description: We study the clustering properties of the first galaxies formed in the Universe. We find that, due to chemical enrichment of the inter-stellar medium by isolated Population III stars formed in mini-halos at redshift z>30, the (chronologically) first galaxies are composed of metal-poor Population II stars and are highly clustered on small scales. In contrast, chemically pristine galaxies in halos with mass M~10^8 M_sun may form at z<20 in relatively underdense regions of the Universe. This occurs once self-enrichment by Population III in mini-halos is quenched by the build-up of an $H_2$ photo-dissociating radiative background in the Lyman-Werner bands. We find that these chemically pristine galaxies are spatially uncorrelated. Thus, we expect that deep fields with the James Webb Space Telescope may detect clusters of chemically enriched galaxies but individual chemically pristine objects. We predict that metal-free galaxies at 10 <= z <= 15$ have surface densities of about 80 per square arcmin and per unit redshift but most of them will be too faint even for JWST. However, the predicted density makes these objects interesting targets for searches behind lensing clusters.

description: We analyse predictions of the CR lepton fluxes at the Earth of both secondary and primary origins, evaluate the theoretical uncertainties, and determine their level of consistency with respect to the available data. For propagation, we use a relativistic treatment of the energy losses for which we provide useful parameterizations. We compute the secondary components by improving on the method that we derived earlier for positrons. For primaries, we estimate the contributions from astrophysical sources (supernova remnants and pulsars) by considering all known local objects within 2 kpc and a smooth distribution beyond. We find that the electron flux in the energy range 5-30 GeV is well reproduced by a smooth distant distribution of sources with index $γ\sim 2.3-2.4$, while local sources dominate the flux at higher energy. For positrons, local pulsars have an important effect above 5-10 GeV. Uncertainties affecting the source modeling and propagation are degenerate and each translates into about one order of magnitude error in terms of local flux. The spectral shape at high energy is weakly correlated with the spectral indices of local sources, but more strongly with the hierarchy in their distance, age and power. Despite the large theoretical errors that we describe, our global and self-consistent analysis can explain all available data without over-tuning the parameters, and therefore without the need to consider any exotic physics. Though a \emph{standard paradigm} of Galactic CRs is well established, our results show that we can hardly talk about any \emph{standard model} of CR leptons, because of the very large theoretical uncertainties. Our analysis provides details about the impact of these uncertainties, thereby sketching a roadmap for future improvements.

Stellar wobble caused by a binary system: Can it really be mistaken as an extra-solar planet?

description: The traditional method for detecting extra-solar planets relies on measuring a small stellar wobble which is assumed to be caused by a planet orbiting the star. Recently, it was suggested that a similar stellar wobble could be caused by a close binary system (Schneider and Cabrera, 2006). Here we show that, although the effect of a close binary system can at first sight be mistaken as a planetary companion to the star, more careful analysis of the observational data should allow us to distinguish between the two effects.

Dimensional Reduction and Vacuum Structure of Quiver Gauge Theory

Year: 2009

description: We describe the structure of the vacuum states of quiver gauge theories obtained via dimensional reduction over homogeneous spaces, in the explicit example of SU(3)-equivariant dimensional reduction of Yang-Mills-Dirac theory on manifolds of the form M x CP(2). We pay particular attention to the role of topology of background gauge fields on the internal coset spaces, in this case U(1) magnetic monopoles and SU(2) instantons on CP(2). The reduction of Yang-Mills theory induces a quiver gauge theory involving coupled Yang-Mills-Higgs systems on M with a Higgs potential leading to dynamical symmetry breaking. The criterion for a ground state of the Higgs potential can be written as the vanishing of a non-abelian Yang-Mills flux on the quiver diagram, regarded as a lattice with group elements attached to the links. The reduction of SU(3)-symmetric fermions yields Dirac fermions on M transforming under the low-energy gauge group with Yukawa couplings. The fermionic zero modes on CP(2) yield exactly massless chiral fermions on M, though there is a unique choice of spin(c) structure on CP(2) for which some of the zero modes can acquire masses through Yukawa interactions. We work out the spontaneous symmetry breaking patterns and determine the complete physical particle spectrum in a number of explicit examples, some of which possess quantum number assignments qualitatively analogous to the manner in which vector bosons, quarks and leptons acquire masses in the standard model.

We investigate the dynamics and stability of bright-soliton wave packets in one-dimensional tilted optical lattices with a modulated mean-field interaction $g(t)$. By means of a time-reversal argument, we prove the stability of Bloch oscillations of breathing solitons that would be quasistatically unstable. Floquet theory shows that these breathing solitons can be more stable against certain experimental perturbations than rigid solitons or even non-interacting wave packets.

description: Because the planets of a system form in a flattened disk, they are expected to share similar orbital inclinations at the end of their formation. The high-precision photometric monitoring of stars known to host a transiting planet could thus reveal the transits of one or more other planets. We investigate here the potential of this approach for the M dwarf GJ 1214 that hosts a transiting super-Earth. For this system, we infer the transit probabilities as a function of orbital periods. Using Monte-Carlo simulations we address both the cases for fully coplanar and for non-coplanar orbits, with three different choices of inclinations distribution for the non-coplanar case. GJ 1214 reveals to be a very promising target for the considered approach. Because of its small size, a ground-based photometric monitoring of this star could detect the transit of a habitable planet as small as the Earth, while a space-based monitoring could detect any transiting habitable planet down to the size of Mars. The mass measurement of such a small planet would be out of reach for current facilities, but we emphasize that a planet mass would not be needed to confirm the planetary nature of the transiting object. Furthermore, the radius measurement combined with theoretical arguments would help us to constrain the structure of the planet.

description: IPR refers to legal ownership by a person or business of an invention/discovery of an invention / discovery attached to particulate product or processes which protects the owner against unauthorised copying or imitation. IPR procedures includes patenting, trademarks, trade secrets, design, varieties, pharma products, database rights etc. Patent is an exclusive right granted by law to applicants/assignees to make use of and exploit their inventions for a limited period of time. The patent holder has the legal right to exclude others from commercially exploiting his invention. An invention should satisfy the three conditions of novelty, inventiveness and usefulness. Earthworms are soil organisms that are known from Darwinian era which perform functions such as improving soil fertility, used as food or bait and also for medicinal and cosmetic uses. They are very sensitive organisms and the rearing procedures need to be standardised. Various attempts were made to patent the useful aspects of earthworm starting from their culturing units to their medicinal properties. This paper highlights the important patents that were filed in beneficial aspects of earthworm and its culturing.

description: As an alternative to dark energy that explains the observed acceleration of the universe, it has been suggested that we may be at the center of an inhomogeneous isotropic universe described by a Lemaitre-Tolman-Bondi (LTB) solution of Einstein's field equations. To test this possibility, it is necessary to solve the null geodesics. In this paper we first give a detailed derivation of a fully analytical set of differential equations for the radial null geodesics as functions of the redshift in LTB models. As an application we use these equaions to show that a positive averaged acceleration $a_D$ obtained in LTB models through spatial averaging can be incompatible with cosmological observations. We provide examples of LTB models with positive $a_D$ which fail to reproduce the observed luminosity distance $D_L(z)$. Since the apparent cosmic acceleration $a^{FLRW}$ is obtained from fitting the observed luminosity distance to a FLRW model we conclude that in general a positive $a_D$ in LTB models does not imply a positive $a^{FLRW}$.

Some aspects of the hydrology of ice-damned lakes : observations on Summit Lake, British Columbia.
Creators: name: Gilbert, Robert
Publisher: name: University of British Columbia
Year: 2011

description: The first known self-draining of Summit Lake occurred in December 1961, followed by similar events in November 1965, September 1967, and November 1968. It has been noted that the rate of draining increases rapidly until the lake is empty (Mathews 1969). In August 1967 it was also noted that the runoff per unit area from the basin of Summit Lake, based on the rate of water volume change in the lake and overflow from the lake, was approximately one half the runoff per unit area from a glacierized basin to the north. It was suspected that at least part of this difference was due to leakage through the ice dam. More detailed observations made in July and August 1968 of the water balance of the lake basin indicate that, in August, there probably existed a leak possibly as large as 3 to 5 m³ sec ̄¹ . The tracing of lake water with fluorescent dye on three occasions also indicated the existence of a leak. Records of lake temperature from surface to bottom were kept from July through September with the results that: a) the warmest water was found at the bottom, and the coldest at approximately one third depth in most cases, b) the warmest temperatures occurred in the north end of the lake in early July; water temperatures decreased southward toward the ice dam and at all locations through the summer, and c) a mean water temperature of approximately 1°C is estimated for July decreasing to 0.7°C by September. For the 1965 draining a lake water temperature of 0.2°C is sufficient with the heat generated due to loss of potential energy to account for the enlargement of the tunnel in the terminal stages of draining, whereas a water temperature of 0.9°C is required for the 1967 flood. No evidence of sudden density overturn of the lake water could be found either from the temperature measurements or the results of dye tracing in the lake water in 1969. Water temperature records on three streams flowing into the lake indicate that from the entire drainage basin approximately 320 x 10¹º calories per day of heat may have been advected to the lake in August 1968.

description: The model by Braginskii for the viscous stress tensor is used to determine the shear and gyroviscous forces acting within a toroidally confined plasma. Comparison is made to a previous evaluation which contains an inconsistent treatment of the radial derivative and neglects the effect of the pitch angle. Parallel viscosity contributes a radial shear viscous force which may develop for sufficient vertical asymmetry to the ion velocity profile. An evaluation is performed of this radial viscous force for a tokamak near equilibrium which indicates qualitative agreement between theory and measurement for impure plasma discharges with strong toroidal flow.

description: The effects of non-adiabatic and Coriolis couplings on the bound states of the He(2 ^3S_1)+He(2 ^3P_j) system, where j=0,1,2, are investigated using the recently available ab initio short-range $^{1,3,5}Σ^+_{g,u}$ and $^{1,3,5}Π_{g,u}$ potentials computed by Deguilhem et al. (J. Phys. B: At. Mol. Opt. Phys. 42 (2009) 015102). Three sets of calculations have been undertaken: single-channel, multichannel without Coriolis couplings and full multichannel with Coriolis couplings. We find that non-adiabatic effects are negligible for $0^-_u,0^{\pm}_g,1_u,2_g,2_u,3_g$ Hund case (c) sets of levels in the j=2 asymptote but can be up to 15% for some of the $0^+_u$ and $1_g$ sets of levels where near degeneracies are present in the single-channel diagonalized potentials. Coriolis couplings are most significant for weakly bound levels, ranging from 1-5% for total angular momenta J=1,2 and up to 10% for J=3. Levels near the j=1 and j=0 asymptotes agree closely with previous multichannel calculations based upon long-range potentials constructed from retarded resonance dipole and dispersion interactions. Assignment of theoretical levels to experimental observations using criteria based upon the short-range character of each level and their coupling to metastable ground states produces well matched assignments for the majority of observations. After a 1% increase in the slope of the $^5Σ^+_{g,u}$ and $^5Π_{g,u}$ input potentials near the classical turning point is applied, improved matching of previous assignments is obtained and further assignments can be made, reproducing very closely the number of experimental observations.

description: The optical birefringence of rod-like nematogens (7CB, 8CB), imbibed in parallel silica channels with 10 nm diameter and 300 micrometer length, is measured and compared to the thermotropic bulk behavior. The orientational order of the confined liquid crystals, quantified by the uniaxial nematic ordering parameter, evolves continuously between paranematic and nematic states, in contrast to the discontinuous isotropic-to-nematic bulk phase transitions. A Landau-de Gennes model reveals that the strength of the orientational ordering fields, imposed by the silica walls, is beyond a critical threshold, that separates discontinuous from continuous paranematic-to-nematic behavior. Quenched disorder effects, attributable to wall irregularities, leave the transition temperatures affected only marginally, despite the strong ordering fields in the channels.

description: We describe how to compute the intersection of two Lucas sequences of the forms $\{U_n(P,\pm 1) \}_{n=0}^{\infty}$ or $\{V_n(P,\pm 1) \}_{n=0}^{\infty}$ with $P\in\mathbb{Z}$ that includes sequences of Fibonacci, Pell, Lucas, and Lucas-Pell numbers. We prove that such an intersection is finite except for the case $U_n(1,-1)$ and $U_n(3,1)$ and the case of two $V$-sequences when the product of their discriminants is a perfect square. Moreover, the intersection in these cases also forms a Lucas sequence. Our approach relies on solving homogeneous quadratic Diophantine equations and Thue equations. In particular, we prove that 0, 1, 2, and 5 are the only numbers that are both Fibonacci and Pell, and list similar results for many other pairs of Lucas sequences. We further extend our results to Lucas sequences with arbitrary initial terms.

The Refractive Index of Curved Spacetime II: QED, Penrose Limits and Black Holes

description: This work considers the way that quantum loop effects modify the propagation of light in curved space. The calculation of the refractive index for scalar QED is reviewed and then extended for the first time to QED with spinor particles in the loop. It is shown how, in both cases, the low frequency phase velocity can be greater than c, as found originally by Drummond and Hathrell, but causality is respected in the sense that retarded Green functions vanish outside the lightcone. A "phenomenology" of the refractive index is then presented for black holes, FRW universes and gravitational waves. In some cases, some of the polarization states propagate with a refractive index having a negative imaginary part indicating a potential breakdown of the optical theorem in curved space and possible instabilities.

description: Excerpts from the report: Ranching practices on mountain meadows in the Western United States have been under research since 1950. Comparisons have been made between ranches operated by traditional procedures and those on which modern research findings were applied. This publication gives some facts and figures, and reports the important conclusions drawn from these comparisons. A survey showed that information acquired through research was being applied mostly by ranchers who lived near experimental sites or who attended field-day demonstrations. Some of these ranchers were able to increase their production as much as 600 percent. They learned how to conserve water by applying less to the meadow and using the surplus on new lands. They learned how to grow about 5 tons of hay where 1 grew before, and how to produce about 6 times as much beef on the acreage they owned. These ranchers centered their efforts on the improvement of water efficiency, area efficiency, soil efficiency, crop adaptation, forage management, and livestock management. They regarded the cost of many of the improvements as capital investment.
Colloidal charge reversal: Dependence on the ionic size and the electrolyte concentration

description: Extensive Monte Carlo simulations and scaling arguments are used to study the colloidal charge reversal. The critical colloidal surface charge density $σ_c$ at which the reversal first appears is found to depend strongly on the ionic size. We find that $σ_c$ has an inflection point as a function of the electrolyte concentration. The width of the plateau region in the vicinity of the inflection point depends on the temperature and the ionic radius $a$. In agreement with the theoretical predictions it is found that the critical colloidal charge above which the electrophoretic mobility becomes reversed diverges as $Z_c \sim 1/a^2$ in the limit $a \to 0$.

Reduction of thio-molybdate in aqueous solutions

description: The high temperature behaviour of the molybdenum (VI) -sulphur (-II) -water system in the presence of an ammoniacal buffer was studied. At 150°C. all species of the form MoO(4-x)S(2¯/x) were shown to exist and the stability constants of mono-, di-, tri-, and tetra-thiomolybdate were 2.3 x 10(2) M.(-1), 3.5 x 10(5) M.(-2), 2.7 x 10(8) M.(-3), 7.0 x 10(10) M.(-4), respectively. There were strong indications of the formation of protonated species, Mo(SH)(6), in solutions containing low concentration of free ammonia. Application of reducing gases to this system produced a mixture of a sulphide and an oxide of molybdenum, whose composition depended on the initial composition of the solution. Under hydrogen, the reduction reaction was autocatalytic, rate being first order in product amount and hydrogen pressure. A mechanism was proposed in which the rate determining step was heterogeneous activation of hydrogen on the surfaces of precipitates followed by two paths, one to produce the sulphide and the other to produce the oxide. The proportion of the sulphide to the oxide was dependent on the solution composition, the higher the fractional distribution of tetra-thiomolybdate and the higher the concentration of hydrogen ion, the more the sulphide being produced. Under carbon monoxide the reduction reaction was found to have an induction period. The molybdenum in solution then followed a linear decrease in concentration with time. The slope of this plot showed Langmuir type of dependence on both molybdenum concentration and pressure. A mechanism was proposed in which the rate determining step was a slow decomposition of some complex between thiomolybdates and carbon monoxide adsorbed strongly on catalytic precipitate which was produced during the induction period.

description: We derive a formula for the gravitational part of the spectral action for Dirac operators on 4-dimensional manifolds with totally anti-symmetric torsion. We find that the torsion becomes dynamical and couples to the traceless part of the Riemann curvature tensor. Finally we deduce the Lagrangian for the Standard Model of particle physics in presence of torsion from the Chamseddine-Connes Dirac operator.

Stellar Disruptions by Supermassive Black Holes

description: In this thesis I present numerical simulations of the tidal disruption of stars by supermassive black holes. These events, commonly referred to as tidal disruption events (TDEs), occur when a star passes too close to the supermassive black hole residing at the centre of a galaxy. When the star gets too close, the tidal force from the black hole is strong enough to tear the star apart into a stream of debris. Some of the debris falls back towards the black hole, forming an accretion flow that produces a luminous flare. TDEs are important astrophysical events as they have the potential to provide detailed understanding of stars and black holes in the Universe. However, to understand what we see we need detailed theoretical models that account for a variety of possible effects. In this thesis I provide new numerical simulations that explore different physical effects and the impact they have on the fallback rate and thus the lightcurves of TDEs. These include simulating spinning stars, and also simulating stars with density profiles that are taken from a stellar evolution code rather than the usual polytropic approximation. I also investigate the numerical convergence of TDE simulations with large impact parameter where the star reaches a pericentre that is much smaller than the tidal radius. These numerical simulations have advanced our understanding of the dynamics of TDEs, and will be useful for future interpretation of observational data in this area.
A refinement of the Conway-Gordon theorems

description: In 1983, Conway-Gordon showed that for every spatial complete graph on 6 vertices, the sum of the linking numbers over all of the constituent 2-component links is congruent to 1 modulo 2, and for every spatial complete graph on 7 vertices, the sum of the Arf invariants over all of the Hamiltonian knots is also congruent to 1 modulo 2. In this article, we give integral lifts of the Conway-Gordon theorems above in terms of the square of the linking number and the second coefficient of the Conway polynomial. As applications, we give alternative topological proofs of theorems of Brown-Ramirez Alfonsin and Huh-Jeon for rectilinear spatial complete graphs which were proved by computational and combinatorial methods.

description: This research is about how corona virus reshaped international relations and how applied Kent's theory will help to explain future variables as a result of Covid 19. In addition, covid 19 has reinvigorated nationalism and undermined globalisations. States respective of the diplomatic relations are closing each other border, pushing states to live within its own means. Some states thus shall capitalise on the effects of corona virus on powerful states to create multiple hegemonies which will ultimately undermine the unipolar position of the USA. Health pandemics thus are now a key variable in international relations and diplomacy, worldover. Of note, if the human rights considerations in the global pandemics. States are begining to undermine the pacta sunt servanda doctrine, especially the pulling off of the USA from WHO for failing to manipulate WHO to be part of its conspiracy theory against China.
