Sediment budget of gold and magnetite and their distribution in stream sediment in lower Harris Creek, south-central British Columbia, Canada
Creators: name: Hou, Zhihui
Publisher: name: University of British Columbia
Year: 2009

description: Although understanding the development of anomalous dispersion trains of gold in stream sediment is important to design and interpretation of exploration geochemical surveys, it has not been studied systematically with respect to variations in supply and transport of sediment. The problem is addressed by applying the sediment budget approach, with the following functional form: I(nput) - S(torage) = O(utput) Harris Creek, a gold-rich stream in south-central British Columbia was chosen as the study area. Primary sources of sediment are landslides in glacial deposits; secondary sources include bank erosion, erosion of sediment accumulated behind log jams, and sediment from tributary streams. Transport of bedload sediments within the Harris Creek drainage basin is strongly seasonal and dependent on the magnitude of the annual snowmelt flood. Field methods included collection of representative geochemical samples; direct field measurement of erosion; and collection of bedload samples using Helley-Smith samplers. Samples were analyzed in the laboratory to determine gold and magnetite. The data show that the supply of gold is discontinuous both spatially and temporally, with little or no gold being delivered to or transported out of Harris Creek during years with low or normal flood discharges (<20 m3/s). During years of large snow meltwater floods gold is transported for brief periods during very high discharge events. Coarse gold (<0.149>0.053 mm) is preferentially deposited in the voids at bar heads with exceptionally anomalous values at bar heads at breaks in slope. Conversely, fine gold (<0.053 mm) is swept in suspension over bar heads to deposit at bar tails but also has peak values at breaks in slope. Estimates of input and output of sediment, magnetite and gold show that gold is less readily mobilized and transported out of Harris Creek than magnetite and sediment. Through time, this has resulted in development of substantially greater concentrations of gold (up to twenty times) in stream sediment in Harris Creek than in the glacial deposits that are the primary sources of sediment. With respect to the anomaly dilution model in exploration geochemistry, the combined effect of accumulation of gold at breaks in slope and dilution by material derived from landslides create an apparent cut-off for gold anomalies a short distance downstream from a landslide.

description: The Multi-conjugate Adaptive Optics RelaY (MAORY) should provide 30% SR in K band (50% goal) on half of the sky at the South Galactic Pole. Assessing its performance and the sensitivity to parameter variations during the design phase is a fundamental step for the engineering of such a complex system. This step, centered on numerical simulations, is the connection between the performance requirements and the Adaptive Optics system configuration. In this work we present MAORY configuration and performance and we justify theAdaptive Optics system design choices.

Subjects: subject: Transportation Engineering

description: Pavement Management is becoming increasingly more important in an era of limited budgets and aging pavement structures, State Highway Agencies (SHA) are attempting to manage the pavements under their jurisdiction more carefully and economically. All pavement management systems include all or some of the following items as inputs: (1) pavement distress, (2) serviceability or rideability, (3) inventory of the system, (4) structural adequacy, (5) traffic volumes and loadings, and (6) some form of performance history. This report documents Kentucky's present pavement management system. In addition, the duties and goals of the Pavement Management Branch are catalogged and described. Methods for rating pavements are described. The allocation of funds and how this allocation is calculated are described. Methods of determining estimates for rehabilitation needs are also described. A description of the organization and flow of information in the PMS is given in detail. Comparisons are made between Kentucky's PMS and the elements of a pavement management system to be required by the Federal Highway Administration in 1993. Kentucky's PMS is well advanced and most of the elements in the Federal Guidelines are already in place or are in some stage of development. Life-cycle costs analysis procedures need to be developed and adopted. Greater use of the present data bases is encouraged.

description: To change the nature of an object into a new figure is like giving birth to it all over. The study examined the prospects accrued to using found objects as a tool for curbing land pollution in Gombe metropolis, Nigeria. Data was collected from existing literature, visit to dump sites, interview with scavengers and the immediate communities. The result shows that there are several refuse dumpsites (legal and illegal) within the metropolis. Solid wastes like metals, plastics, woods, glasses, ceramics, leather, stones among others are disposed at the sites. These wastes, to the artists, are known as found objects. They are burnt, allowed to litter the environment and decay or scavenged for either reuse, recycling or reclamation. This paper, therefore, recommends the need for using found object materials at the dumpsites to creatively produce works of art known as found object sculptures, using them as a tool for curbing solid waste decomposition and burning which is hazardous to groundwater and climatic condition of Gombe Metropolis and the world at large.

description: An objective of this study was to review and analyze claims made against the Kentucky Transportation Cabinet through the Board of Claims. Another objective was to review the current state-of-the-art related to tort liability and highway agencies. This was accomplished by reviewing the literature and contacting other state highway agencies. Using information obtained from these various sources, recommendations were made relating to the establishment of an effective risk management program.  Information from Board of Claims cases was obtained for the years 1981 through 1989 and then analyzed. This information included the date of the claim, the county where the action on which the claim was based occurred, the reason for the claim, the amount sought, the decision, and the date of the decision.

description: At the quantum many-body level, atom-light interfaces generally remain challenging to solve for or understand in a non-perturbative fashion. Here, we consider a waveguide quantum electrodynamics model, where two-level atoms interact with and via propagating photons in a one-dimensional waveguide, and specifically investigate the interplay of atomic position disorder, multiple scattering of light, quantum nonlinear interactions and dissipation. We develop qualitative arguments and present numerical evidence that such a system exhibits a many-body localized~(MBL) phase, provided that atoms are less than half excited. Interestingly, while MBL is usually formulated with respect to closed systems, this system is intrinsically open. However, as dissipation originates from transport of energy to the system boundaries and the subsequent radiative loss, the lack of transport in the MBL phase makes the waveguide QED system look essentially closed and makes applicable the notions of MBL. Conversely, we show that if the system is initially in a delocalized phase due to a large excitation density, rapid initial dissipation can leave the system unable to efficiently transport energy at later times, resulting in a dynamical transition to an MBL phase. These phenomena can be feasibly realized in state-of-the-art experimental setups.

description: We investigate the collective aspects of Rydberg excitation in ultracold mesoscopic systems. Strong interactions between Rydberg atoms influence the excitation process and impose correlations between excited atoms. The manifestations of the collective behavior of Rydberg excitation are the many-body Rabi oscillations, spatial correlations between atoms as well as the fluctuations of the number of excited atoms. We study these phenomena in detail by numerically solving the many-body Schrëdinger equation.

description: We have shown that the weak-coupling limit superconductors are well described by $ q \sim 1 $, where $ q $ is a real parameter which characterizes the degree of nonextensivity of Tsallis' entropy. Nevertheless, small deviations with respect to q=1 provide better agreement when compared with experimental results. We have also shown that the generalized BCS theory with $ q \neq 1 $ exhibit power-law behavior of several measurable macroscopic functions in the low-temperature regime. These power-law properties are found in many high-Tc oxides superconductors and motivated us to extend Tsallis' entropy calculations to these systems. Therefore, we have calculated the phase diagram and the specific heat and we compare our results with the experimental data for the YBCO compound.

description: Some of the most remarkable tilings and discrete quasiperiodic sets used in quasicrystal physics can be obtained by using strip projection method in a superspace of dimension four, five or six, and the projection of a unit hypercube as a window of selection. We present some mathematical results which allow one to use this very elegant method in superspaces of dimension much higher, and to generate discrete quasiperiodic sets with a more complicated local structure by starting from the corresponding covering cluster. Hundreds of points of these sets can be obtained in only a few minutes by using our computer programs.

Subjects: subject: Transportation Engineering

description: Prior to 1989, highway edge drains were backfilled with the existing trench material and dynamically compacted with a tamping shoe. The net result was damage to the inner core of the edge drain.  In response to these problems the installation specification was revised in 1989 to insure the integrity of the drainage system. The revised method of installation consisted of moving the panel to the shoulder side of the trench and then flushing a sand slurry into the trench for backfill. Flushing the sand eliminates the need for mechanical compaction.  Since 1989, two projects have been completed using the revised special note for installation and another is currently under construction. This report discusses the performance of these installations.

description: The FRS-ESR facility at GSI provides unique conditions for precision measurements of large areas on the nuclear mass surface in a single experiment. Values for masses of 604 neutron-deficient nuclides (30<=Z<=92) were obtained with a typical uncertainty of 30 microunits. The masses of 114 nuclides were determined for the first time. The odd-even staggering (OES) of nuclear masses was systematically investigated for isotopic chains between the proton shell closures at Z=50 and Z=82. The results were compared with predictions of modern nuclear models. The comparison revealed that the measured trend of OES is not reproduced by the theories fitted to masses only. The spectral pairing gaps extracted from models adjusted to both masses, and density related observables of nuclei agree better with the experimental data.

description: This paper reports the characterization of hollow metallic waveguides (HMW) to be used as single-mode wavefront filters for nulling interferometry in the 6-20 microns range. The measurements presented here were performed using both single-mode and multimode conductive waveguides at 10.6 microns. We found propagation losses of about 16dB/mm, which are mainly due to the theoretical skin effect absorption in addition to the roughness of the waveguide metallic walls. The input and output coupling efficiency of our samples has been improved by adding tapers to minimize the impedance mismatch. A proper distinction between propagation losses and coupling losses is presented. Despite their elevate propagation losses, HMW show excellent spatial filtering capabilities in a spectral range where photonics technologies are only emerging.

description: A high intensity source of a single neutrino flavour with known spectrum is most desirable for precision measurements, the consensus direction for the future. The beta beam is an especially suitable option for this. We discuss the prospects of a very long baseline beta beam experiment with a magnetized iron calorimeter detector. In particular, with the source at CERN and the detector at the proposed India-based Neutrino Observatory (INO) the baseline is near the `magic' value where the effect of the CP phase is small. We observe that this experiment will be well suited to determine the sign of $m_3^2 - m_2^2$ and will be capable of probing $θ_{13}$ down to about 1$^\circ$.

description: We discuss the relationship between the phase diagram of the Q=0 state Potts model, the arboreal gas model, and the supersphere sigma model S^{0,2} = OSP(1/2) / OSP(0/2). We identify the Potts antiferromagnetic critical point with the critical point of the arboreal gas (at negative tree fugacity), and with a critical point of the sigma model. We show that the corresponding conformal theory on the square lattice has a non-linearly realized OSP(2/2) = SL(1/2) symmetry, and involves non-compact degrees of freedom, with a continuous spectrum of critical exponents. The role of global topological properties in the sigma model transition is discussed in terms of a generalized arboreal gas model.

Intrinsic randomness, uncertainty due to the incompatibility of two observables, monogamy of correlations, impossibility of perfect cloning, privacy of correlations, bounds in the shareability of some states; all these phenomena are solely a consequence of the no-signaling principle and nonlocality. In particular, it is shown that for any distribution, the properties of (i) nonlocal, (ii) no arbitrarily shareable and (iii) positive secrecy content are equivalent.

It will be able to work in closed loop on up to three natural guide stars down to H=19, providing a sky coverage larger than 50% in the south galactic pole. Such goals and the exploration of a large MCAO system parameters space have required a combination of analytical and end- to-end simulations to assess performance, sky coverage and drive the design. In this work we report baseline performance, statistical sky coverage and parameters sensitivity analysis done in the phase-A instrument study.

description: A simple - yet plausible - model for B-type vortex breakdown flows is postulated; one that is based on the immersion of a pair of slender coaxial vortex rings in a swirling flow of an ideal fluid rotating around the axis of symmetry of the rings. It is shown that this model exhibits in the advection of passive fluid particles (kinematics) just about all of the characteristics that have been observed in what is now a substantial body of published research on the phenomenon of vortex breakdown. Moreover, it is demonstrated how the very nature of the fluid dynamics in axisymmetric breakdown flows can be predicted and controlled by the choice of the initial ring configurations and their vortex strengths. The dynamic intricacies produced by the two ring + swirl model are illustrated with several numerical experiments.

description: Common-envelope evolution is important in the formation of neutron star binaries within the isolated binary formation channel. As a neutron star inspirals within the envelope of a primary massive star, it accretes and spins up. Because neutron stars are in the strong-gravity regime, they have a substantial relativistic mass deficit, i.e., their gravitational mass is less than their baryonic mass. This effect causes some fraction of the accreted baryonic mass to convert into neutron star binding energy. The relativistic mass deficit also depends on the nuclear equation of state, since more compact neutron stars will have larger binding energies. We model the mass growth and spin-up of neutron stars inspiraling within common-envelope environments and quantify how different initial binary conditions and hadronic equations of state affect the post-common-envelope neutron star's mass and spin. From these models, we find that neutron star mass growth is suppressed by $\approx 15-30\%$. We also find that for a given amount of accreted baryonic mass, more compact neutron stars will spin-up faster while gaining less gravitational mass, and vice versa. This work demonstrates that a neutron star's strong gravity and nuclear microphysics plays a role in neutron-star-common-envelope evolution, in addition to the macroscopic astrophysics of the envelope. Strong gravity and the nuclear equation of state may thus affect both the population properties of neutron star binaries and the cosmic double neutron star merger rate.

description: We present medium-resolution optical spectra of the secondary star in the high Galactic latitude black hole X-ray binary XTE J1118+480 and determine the abundance of Mg, Al, Ca, Fe, and Ni in its atmosphere. For all the elements investigated we find supersolar abundances; thus, we reject the hypothesis that the black hole came from the direct collapse of an ancient massive halo star. The compact primary most likely formed in a supernova event of a massive star whose nucleosynthetic products polluted the secondary star. The observed element abundances and their ratios can be explained using a variety of supernova models with a wide range of metallicities. While an explosive origin in the Galactic halo or thick disk cannot be discarded, a metal-rich progenitor is clearly favored by the observed abundance pattern. This suggests that the black hole was produced in the Galactic thin disk with a violent natal kick, propelling the X-ray binary to its current location and orbit.

description: We present quantum cascade laser (QCL) frequency comb devices with engineered waveguides for managing the dispersion. The QCL waveguide consists of multiple sections with different waveguide widths. The narrow and wide sections of the waveguide are designed in a way to compensate the group velocity dispersion (GVD) of each other and thereby produce a flat and slightly negative GVD for the QCL. The QCL exhibits continuous comb operation over a large part of the dynamic range of the laser. Strong and narrow-linewidth intermode beatnotes are achieved in more than 300 mA wide operation current range. The comb device features also considerably high output power (>380 mW) and wide optical bandwidth (>55 cm-1)

description: Paint inspections were performed on 19 steel bridges. Those structures employed various high-performance sacrificial and barrier paints. Those paints were used singly and in combination. The surface preparation varied for some of those paint systems.  The inspections included four girder bridges that had original paint and 15 others, mostly trusses that were repainted. Kentucky Transportation Center personnel also monitored several bridges during repainting operations. The inspections revealed that the original paint was in excellent condition. Most of the coatings on the repainted bridges were performing well. Some of those bridges have some spot corrosion. Only one of those bridges showed signs of widespread coating failure.  The high-performance coatings were performing well. Most of the corrosion and paint deterioration observed is believed to be related to inadequate surface preparation. Paint inspection provided by the Kentucky Transportation Cabinet is good.

description: This report discusses the investigation of the premature cracking that occurred on the National Turn pike, Jefferson County (1989). A detailed distress survey was performed evaluating each slab throughout the project site. Falling Weight Deflectometer testing was performed on every third slab. In addition subgrade samples were taken, along with the installation of three water monitoring wells. Laboratory test were conducted on the subgrade samples.  Damage that occurred near the curb inlets and manholes is probably due to insufficient compaction. The remaining damage is most likely related to the combined effects of a very soft subgrade, high water tables, and traffic loads that are applied to the saturated or near-saturated subgrade.  Because complete reconstruction of this project is economically unfeasible, an intense maintenance program is recommended.

description: Concern has grown in recent years over the seismic activity of the New Madrid seismic zone in Western Kentucky. In 1987, the Kentucky Transportation Cabinet commissioned the Kentucky Transportation Center to analyze and assess the possible effects of an earthquake on highway facilities. Since 1987, over 1,000 miles of priority routes have been recommended for the transportation of goods and services after a major earthquake. This report summarizes the mitigation research that has been conducted. This report also discusses a plan for continuing earthquake mitigation in Kentucky through seminars, discusses bridge retrofitting, and makes recommendations for a post earthquake response.
Performance Report on Corrugated Polyethylene Pipe, N-12

description: This paper documents the installation and performance ofN-12 pipe installed during construction of South Forbes Road in Fayette County, KY 54 in Daviess County, US 62 in McCracken County, Nicholasville Road in Fayette County, and US 68/KY 80 in Warren County. The pipe is manufactured by Advanced Drainage Systems, Inc., and is designated as ADS N-12. ADS N-12 is a corrugated high-density polyethylene (HDPE) pipe. The pipe has a corrugated exterior for increased strength and a smooth interior to provide maximum flow capacity.  The N-12 pipe requires less equipment and fewer personnel than steel or concrete pipe for installation. From visual observations at all five sites, extreme care should be taken during backfilling around the pipe above the bedding material. On US 62, KY 54, and US 68/KY 80 the pipes were not completely covered with bedding material. Cuts or tears were found inside the N-12 pipe (5 total). It appears that the tears are occurring where the sections of plastic are wrapped together to form the pipe. The rips are probably occurring due to improper backfilling and unequal loading of the pipe wall. On Forbes Road and Nicholasville Road, the pipes were completely covered with one foot of either sand or crushed stone before the excavated material was placed as backfill. This one-foot cover helps protect the pipe against backfill damage. In several installations, it was apparent the ends of the pipes at the couplings were rarely butted completely together. This permits material to be deposited in those areas. Care should also be taken during construction not to damage the plastic pipe during transportation. Due to the fact the N-12 is lightweight, the pipe has a tendency to rise or drift during backfilling. To eliminate this, the contractors bed each side equally to approximately 1/2 to 3/4 of the pipe height before compacting (depends greatly on the backfill material).

description: The origin of the breaking of conventional linear k_\perp-factorization for hard processes in a nuclear environment is by now well established. The realization of the nonlinear nuclear k_\perp-factorization which emerges instead was found to change from one jet observable to another. Here we demonstrate how the pattern of nonlinear k_\perp-factorization, and especially the role of diffractive interactions, in the production of dijets off nuclei depends on the color properties of the underlying pQCD subprocess.

description: We determine the dark matter pair-wise relative velocity distribution in a set of Milky Way-like halos in the Auriga and APOSTLE simulations. Focusing on the smooth halo component, the relative velocity distribution is well-described by a Maxwell-Boltzmann distribution over nearly all radii in the halo. We explore the implications for velocity-dependent dark matter annihilation, focusing on four models which scale as different powers of the relative velocity: Sommerfeld, s-wave, p-wave, and d-wave models. We show that the J-factors scale as the moments of the relative velocity distribution, and that the halo-to-halo scatter is largest for d-wave, and smallest for Sommerfeld models. The J-factor is strongly correlated with the dark matter density in the halo, and is very weakly correlated with the velocity dispersion. This implies that if the dark matter density in the Milky Way can be robustly determined, one can accurately predict the dark matter annihilation signal, without the need to identify the dark matter velocity distribution in the Galaxy.

description: We propose that the state represented by the Nariai black hole inside de Sitter space is the ground state of the de Sitter gravity, while the pure de Sitter space is the maximal energy state. With this point of view, we investigate thermodynamics of de Sitter space, we find that if there is a dual field theory, this theory can not be a CFT in a fixed dimension. Near the Nariai limit, we conjecture that the dual theory is effectively an 1+1 CFT living on the radial segment connecting the cosmic horizon and the black hole horizon. If we go beyond the de Sitter limit, the "imaginary" high temperature phase can be described by a CFT with one dimension lower than the spacetime dimension. Below the de Sitter limit, we are approaching a phase similar to the Hagedorn phase in 2+1 dimensions, the latter is also a maximal energy phase if we hold the volume fixed.

Reducing nitrogen losses during composting of poultry manure using the natural zeolite clinoptilolite

Publisher: name: University of British Columbia

description: Loss of N via NH₃ volatilization during composting of poultry manure reduces the agronomic value of the end-product and contributes to environmental pollution. The objectives of this study were to evaluate N losses via NH₃ volatilization during aerobic composting of poultry layer manure, examine the potential of natural zeolites to adsorb the volatilized NH₃ during composting, and evaluate the poultry manure-zeolite compost as a controlled-release N fertilizer. Eleven mineral samples were characterized for their physical properties, chemical composition, and NH₄⁺ adsorption capacity. The effectiveness of a clinoptilolite zeolite ZI as an NH₄⁺ adsorbent at pH range 4 to 7 was tested. The kinetics of NH₄⁺ exchange on the zeolite was evaluated at the pH range 4 to 7, initial NH₄⁺ concentrations ranging from 70.1 to 1401 mgN L⁻¹, and a temperature range of 25 to 55 °C. Ammonia emissions were measured during composting of poultry manure with zeolites and other amendments in a laboratory composting simulator. The resulting composts were applied to a sand based medium planted with ryegrass (Lolium multiflorum) where growth, N uptake, and NH₄⁺ and N0₃⁻ leaching were evaluated. The cation exchange capacity (CEC) and purity of the zeolites, with respect to mineralogy and constituent ions, influenced their affinity and adsorptive capacity for NH₄⁺. The amount of NH₄ ⁺ adsorbed increased with increasing pH and NH₄⁺ concentration. The estimated NH₄⁺ adsorption capacity increased linearly with pH (r2 = 0.994), ranging from 9660 mg N L⁻¹ at pH 4 to 13830 mg N L⁻¹ at pH 7. Studies on thermodynamics of NH₄⁺exchange on the zeolite ZI indicated a higher activation energy for desorption (5.65 kJ mol1) than for adsorption (2.32 kJ mol⁻¹). Composting poultry manure with 60% zeolite ZI (weight basis) reduced NH₃ losses by 44.3%. The compost had total N concentration of 17.04 g N kg⁻¹ and a high NH₄ ⁺ concentration (52.8% of the total N). The 60% zeolite Zl-amended compost treatment produced the highest ryegrass dry matter, N accumulation and N use efficiency compared to the other composts evaluated. Nitrogen leaching losses were low. Although composting poultry manure amended with the natural zeolite clinoptilolite can reduce N losses to the atmosphere, recycling it for crop utilization, the cost of the high amount of zeolite required may be prohibitive.

description: Within asymptotically safe Quantum Einstein Gravity (QEG), the quantum 4-sphere is discussed as a specific example of a fractal spacetime manifold. The relation between the infrared cutoff built into the effective average action and the corresponding coarse graining scale is investigated. Analyzing the properties of the pertinent cutoff modes, the possibility that QEG generates a minimal length scale dynamically is explored. While there exists no minimal proper length, the QEG sphere appears to be "fuzzy" in the sense that there is a minimal angular separation below which two points cannot be resolved by the cutoff modes.

description: We present a framework that formulates the quest for the most efficient quantum state tomography scheme as an optimization problem which can be solved numerically. This approach can be applied to a broad spectrum of relevant setups including measurements restricted to a subsystem. To illustrate the power of this method we present results for the six-dimensional Hilbert space constituted by a qubit-qutrit system, which could be realized e.g. by the N-14 nuclear spin-1 and two electronic spin states of a nitrogen-vacancy center in diamond. Measurements of the qubit subsystem are expressed by projectors of rank three, i.e., projectors on half-dimensional subspaces. For systems consisting only of qubits, it was shown analytically that a set of projectors on half-dimensional subspaces can be arranged in an informationally optimal fashion for quantum state tomography, thus forming so-called mutually unbiased subspaces. Our method goes beyond qubits-only systems and we find that in dimension six such a set of mutually-unbiased subspaces can be approximated with a deviation irrelevant for practical applications.

description: We present analytical expressions for optimal entropy-constrained multiple-description lattice vector quantizers which, under high-resolutions assumptions, minimize the expected distortion for given packet-loss probabilities. We consider the asymmetric case where packet-loss probabilities and side entropies are allowed to be unequal and find optimal quantizers for any number of descriptions in any dimension. We show that the normalized second moments of the side-quantizers are given by that of an $L$-dimensional sphere independent of the choice of lattices. Furthermore, we show that the optimal bit-distribution among the descriptions is not unique. In fact, within certain limits, bits can be arbitrarily distributed.
