The Effectiveness of stormwater ponds in contaminant removal from urban stormwater runoff in the Lower Fraser Valley, BC
Creators: name: Brydon, Julia
Publisher: name: University of British Columbia
Year: 2009

description: As urbanization progresses rapidly throughout the Lower Fraser Valley (LFV) and many other areas in Canada, contaminants associated with urban land uses are found in elevated concentrations in urban waterways. One of the most common mitigation methods is the construction of stormwater ponds, which provide detention for volume control and remediation for water quality improvement. The aim of this research is to investigate the quality of the stormwater entering five ponds in urban areas in the LFV and the effectiveness of trace metal and phosphorus removal in these ponds during the wet and dry seasons. Both water and sediment from the inlets and outlets of the ponds are analysed. A new technique of Diffusive Gradient in Thin Films (DGT) was employed to capture available metals over time and determine the accumulation of bioavailable metals during different storm events. The results show that an average of 26% (range 0 - 60%) of the samples of inlet water from the ponds exceeded the guideline for zinc of the Canadian Environmental Quality Guidelines for Freshwater Aquatic Life. Copper and zinc concentrations found in the sediment at the inlets of all ponds exceeded the Probable Effects Level. The concentration of these metals is correlated to traffic volumes and percent impervious cover in the catchments. Zinc concentrations are reduced through the ponds by up to 41% in the water, 65% in the sediments and 78% in bioavailability. Most ponds were not effective in retaining aluminum, iron or manganese in the water and sediments. However, the bioavailable form of these metals is reduced particularly during the wet period by an average of 29% (range -155% to 81%). The extent of vegetation in the ponds had the strongest overall correlation to contaminant reduction in water, sediment and bioavailability, while surface area and volume were correlated to only reductions in manganese. In conclusion, the most effective designs incorporate a combination of vegetation in the pond, a sufficient flow of water throughout the wet season, and a design that aids consistent sedimentation of coarse particles through the pond, while impeding the flow of finer clay particles to allow for remediation.

description: We investigate a complex curve in the $c=1$ string theory which provides a geometric interpretation for different kinds of D-branes. The curve is constructed for a theory perturbed by a tachyon potential using its matrix model formulation. The perturbation removes the degeneracy of the non-perturbed curve and allows to identify its singularities with ZZ branes. Also, using the constructed curve, we find non-perturbative corrections to the free energy and elucidate their CFT origin.

description: We consider the multicomponent Smoluchowski coagulation equation under non-equilibrium conditions induced either by a source term or via a constant flux constraint. We prove that the corresponding stationary non-equilibrium solutions have a universal localization property. More precisely, we show that these solutions asymptotically localize into a direction determined by the source or by a flux constraint: the ratio between monomers of a given type to the total number of monomers in the cluster becomes ever closer to a predetermined ratio as the cluster size is increased. The assumptions on the coagulation kernel are quite general, with isotropic power law bounds. The proof relies on a particular measure concentration estimate and on the control of asymptotic scaling of the solutions which is allowed by previously derived estimates on the mass current observable of the system.

description: We consider time-dependent Gaussian wave packet solutions of the Schrodinger equation (with arbitrary initial central position, x_0, and momentum, p_0, for an otherwise free-particle, but with an infinite wall at x=0, so-called bouncing wave packets. We show how difference or mirror solutions of the form psi(x,t)-psi(-x,t) can, in this case, be normalized exactly, allowing for the evaluation of a number of time-dependent expectation values and other quantities in closed form. For example, we calculate _t explicitly which illustrates how the free-particle kinetic (and hence total) energy is affected by the presence of the distant boundary. We also discuss the time dependence of the expectation values of position, _t, and momentum, _t, and their relation to the impulsive force during the `collision' with the wall. Finally, the x_0,p_0 --> 0 limit is shown to reduce to a special case of a non-standard free-particle Gaussian solution. The addition of this example to the literature then expands on the relatively small number of Gaussian solutions to quantum mechanical problems with familiar classical analogs (free particle, uniform acceleration, harmonic oscillator, unstable oscillator, and uniform magnetic field) available in closed form.

Ince's limits for confluent and double-confluent Heun equations

Subjects: subject: Mathematical Physics (math-ph)

description: We find pairs of solutions to a differential equation which is obtained as a special limit of a generalized spheroidal wave equation (this is also known as confluent Heun equation). One solution in each pair is given by a series of hypergeometric functions and converges for any finite value of the independent variable $z$, while the other is given by a series of modified Bessel functions and converges for $|z|>|z_{0}|$, where $z_{0}$ denotes a regular singularity. For short, the preceding limit is called Ince's limit after Ince who have used the same procedure to get the Mathieu equations from the Whittaker-Hill ones. We find as well that, when $z_{0}$ tends to zero, the Ince limit of the generalized spheroidal wave equation turns out to be the Ince limit of a double-confluent Heun equation, for which solutions are provided. Finally, we show that the Schrödinger equation for inverse fourth and sixth-power potentials reduces to peculiar cases of the double-confluent Heun equation and its Ince's limit, respectively.

description: The hydration phase diagram for sodium cobalt oxyhydrate, Na0.3CoO2*yH2O (y=0, 0.6, 1.3), was determined as a function of relative humidity at 298K. It is found that greater than 75% relative humidity is needed for complete hydration of anhydrous Na0.3CoO2 to the superconducting phase Na0.3CoO2*1.3H2O. Dehydration studies show that a minimum of 43% relative humidity is needed to maintain the stability of the fully hydrated superconducting phase. The intermediate hydrate, Na0.3CoO2*0.6H2O, is stable between 10% and 50% relative humidity on hydration, and 35% to 0% relative humidity on dehydration.

description: Stripped envelope supernovae are a sub-class of core collapse supernovae showing several stages of H/He shell stripping that determines the class: H-free/He-poor SNe are classified as Type Ic, H-poor/He-rich are Type Ib, and H/He-rich are Type IIb. Stripping H/He with only stellar wind requires significantly higher mass loss rates than observed while binary-involved mass transfer may usually not strip enough to produce H/He free SNe. Type Ib/c SNe are sometimes found to include weak H/He transient lines as a product of a trace amount of H/He left over from stripping processes. The extent and mass of the H/He required to produce these lines is not well known. In this work, a 22 M$_{\odot}$ progenitor model is stripped of the H/He shells in five steps prior to collapse and then exploded at four explosion energies. Requiring both optical and NIR He I lines for helium identification does not allow much He mass to be hidden in SE--SNE. Increasing the mass of He above the CO core delays the visibility of O I 7774 in early spectra. Our SN Ib-like models are capable of reproducing the spectral evolution of a set of observed SNe with reasonable estimated $E_\mathrm{k}$ accuracy. Our SN\,IIb-like models can partially reproduce low energy observed SN IIb, but we find no observed comparison for the SN IIb-like models with high $E_\mathrm{k}$.

description: An emerging requirement for the evaluation of the rural development policy is the adoption of an objective method accounting for both material and immaterial achievements, and measuring the performance in order to understand the degree of accomplishment of policy objectives. In this paper we propose a Data Envelopment Analysis (DEA) approach capable of dealing with economic and social indicators, to measure the (relative) technical efficiency of a set of Local Action Groups (LAGs) operating within the LEADER programme. An evaluation exercise referred to eight LAGs located in Italy, is provided to demonstrate the effects of the inclusion of social capital indicator in the evaluation of the LAGs’ performances. In particular, the DEA allows to measure the relative efficiency of the LAGs and to identify the causes of the inefficiency. The outcomes of the analysis may represent a valuable information support for periodical policy review and for the enhancement of best practices.

description: Much is now known about the consistency of Bayesian updating on infinite-dimensional parameter spaces with independent or Markovian data. Necessary conditions for consistency include the prior putting enough weight on the correct neighborhoods of the data-generating distribution; various sufficient conditions further restrict the prior in ways analogous to capacity control in frequentist nonparametrics. The asymptotics of Bayesian updating with mis-specified models or priors, or non-Markovian data, are far less well explored. Here I establish sufficient conditions for posterior convergence when all hypotheses are wrong, and the data have complex dependencies. The main dynamical assumption is the asymptotic equipartition (Shannon-McMillan-Breiman) property of information theory. This, along with Egorov's Theorem on uniform convergence, lets me build a sieve-like structure for the prior. The main statistical assumption, also a form of capacity control, concerns the compatibility of the prior and the data-generating process, controlling the fluctuations in the log-likelihood when averaged over the sieve-like sets. In addition to posterior convergence, I derive a kind of large deviations principle for the posterior measure, extending in some cases to rates of convergence, and discuss the advantages of predicting using a combination of models known to be wrong. An appendix sketches connections between these results and the replicator dynamics of evolutionary theory.

description: We study the inverse cascade of magnetic helicity in conducting fluids by investigating the detailed transfer of helicity between different spherical shells in Fourier space in direct numerical simulations of three-dimensional magnetohydrodynamics (MHD). Two different numerical simulations are used, one where the system is forced with an electromotive force in the induction equation, and one in which the system is forced mechanically with an ABC flow and the magnetic field is solely sustained by a dynamo action. The magnetic helicity cascade at the initial stages of both simulations is observed to be inverse and local (in scale space) in the large scales, and direct and local in the small scales. When saturation is approached most of the helicity is concentrated in the large scales and the cascade is non-local. Helicity is transfered directly from the forced scales to the largest scales. At the same time, a smaller in amplitude direct cascade is observed from the largest scale to small scales.

Self-consistent renormalization group approach to continuous phase transitions in alloys. Application to ordering in $β$-brass

description: A self-consistent (SC) renormalization group approach of the effective medium kind has been developed and applied to the solution of the Ising model (IM). A renormalization group equation in the local potential approximation (LPA) derived previously for spatially homogeneous systems has been extended to the lattice case and supplemented with a self-consistency condition on the pair correlation function. To validate the approach it has been applied to the simple cubic IM and good agreement of the spontaneous magnetization calculated with the use of the SC-LPA equation with the available exact Monte Carlo simulations data has been established. Next the approach has been applied to the bcc IM corresponding to $β$-brass. With the use of the effective pair interaction parameters from available {\em ab initio} calculations the critical temperature, the correlation length and the long range order parameter in the vicinity of the critical point have been calculated in excellent agreement with experimental data. Qualitative and quantitative arguments have been given in support of the suggestion that the experimentally observed decrease of the effective critical exponent of the order parameter in comparison with the universal value is enhanced by the positive value of the second neighbour pair interaction found in the {\em ab initio} calculations.

In this context we derive the equations of motion for the physical variables and check out the dispersion relations obtained from them. Therefore, by the analysis using Symplectic Projector Method (SPM), we can check the results about this type of Lorentz breaking with those in the recent literature: in this sense we can confirm that the configuration of $v^μ$ space-like is stable, and the $v^μ$ time-like carry tachionic modes.

description: Farmers face increasing income uncertainty and the debate is growing on the role of insurance schemes and of public support in this field. This paper applies a PMP modelling approach that takes into explicit consideration risk aversion behaviour to test its applicability to evaluating the potential impact of insurance schemes. This is done by introducing a revenue insurance scheme into a model developed on a small group of crop farms in Italy. The paper represents a preliminary assessment of the soundness of the proposed approach. It identifies some limitations that should be overcome to improve the proposed approach. Despite these limitations, it seems a useful tool to investigate the impact of insurance schemes and policy relevant parameters such as premium and coverage rates. Indeed, it permits the assessment of how this affects production choices, farm profitability and the impact of public support to reduce the net premium paid by farmers.

description: Let $E$ be a uniformly smooth and uniformly convex real Banach space and $E^*$ be its dual space. Suppose $A : E\rightarrow E^*$ is bounded, strongly monotone and satisfies the range condition such that $A^{-1}(0)\neq \emptyset$. Inspired by Alber [2], we introduce Lyapunov functions and use the new geometric properties of Banach spaces to show the strong convergence of an iterative algorithm to the solution of $Ax=0$.

description: The validity of the linear elasticity theory is examined at the nanometer scale by investigating the vibrational properties of silver and gold nanoparticles whose diameters range from about 1.5 to 4 nm. Comparing the vibration modes calculated by elasticity theory and atomistic simulation based on the Embedded Atom Method, we first show that the anisotropy of the stiffness tensor in elastic calculation is essential to ensure a good agreement between elastic and atomistic models. Second, we illustrate the reduction of the number of vibration modes due to the diminution of the number of atoms when reducing the nanoparticles size. Finally, we exhibit a breakdown of the frequency-spectra scaling of the vibration modes and attribute it to surface effects. Some critical sizes under which such effects are expected, depending on the material and the considered vibration modes are given.

description: The paper investigates the effects of the entry price scheme for fresh fruit and vegetables. The analysis is conducted on the EU prices of tomatoes, lemons and apples for some of the main competing countries on the EU domestic markets: Morocco, Argentina, Turkey and China. The econometric analysis is based on testing and estimating a switching vector autoregressive model with endogenous threshold entry price level. The model shows the isolation effects and the accumulation of SIVs above the trigger entry price. This paper contributes to clarify the role played by the EPS in avoid or deter low priced imports from main EU partner Countries.
History and evolution of salmon aquaculture siting policy in British Columbia
Creators: name: Galland, Daniel
Publisher: name: University of British Columbia

description: Salmon aquaculture is the rearing of salmonids for commercial purposes. These practices are typically carried out in saltwater farms located in coastal waters. The process of siting these facilities requires identifying and selecting areas that are economically, socially and environmentally suitable to locate them. Siting salmon aquaculture facilities has become a controversial resource management issue in British Columbia (B.C.), where distance-based criteria ultimately determine the location of these facilities. This thesis focuses on providing insights and concepts to inform and examine the salmon aquaculture facility siting process in B.C. It is argued that regulatory processes and outcomes in the context of a new industry could respond to mechanisms and factors that shape governmental agendas, illustrating how policy can behave reactively rather than in a precautionary manner. In this case, the outcomes of such reactive policies are reflected in siting criteria that yield implicit environmental and socio-economic disadvantages and tradeoffs. This way, siting criteria derive from expert judgements based on best available information while their associated uncertainties may lead to consider less-desirable sites while underestimating or overestimating risks, and overlooking important regional objectives, cumulative impacts and stakeholder values. The thesis further suggests that the future evolution of the salmon aquaculture facility siting process in B.C. could benefit from siting processes that have already been developed and implemented by other sectors. Different lines of reasoning that deal with processes of public negotiation, analytical decision-making and a systems' approach are explored as ways by which the salmon aquaculture facility siting process could evolve in the future toward creating more comprehensive policy.

description: Contrary to Bell scenario, quantum nonlocality can be exploited even when all the parties do not have freedom to select inputs randomly. Such manifestation of nonlocality is possible in networks involving independent sources. One can utilize such a feature of quantum networks for purpose of entanglement detection of bipartite quantum states. In this context, we characterize correlations simulated in networks involving finite number of sources generating quantum states when some parties perform fixed measurement. Beyond bipartite entanglement, we enquire the same for networks involving sources now generating pure tripartite quantum states. Interestingly, here also randomness in input selection is not necessary for every party to generate nonlocal correlation.

description: This paper investigates the cultural underpinnings that govern the use or disuse of sexually explicit Ewe and Mampulli verbs mɔ and nnyabi (have sex) among native Ewe and native Mampulli speakers. A longitudinal study approach and interviews were employed to collect data over a twelve-month period among Ewe speakers of Aflao in the Volta Region of Ghana and Mampulli speakers of Nalerigu in the North East Region. Findings reveal that the cultural underpinnings that govern these taboo words are, first, the Ewe and Mampulli cultures regard sex act as a sacred thing and that using such explicit words in talking about it is too raw and uncultured; second, both cultures are patriarchal or male dominant; third, they permit polygamy but frown on polyandry; finally, the two cultures frown on homosexuality. This study provides a window into the Ewe and Mampulli cultures, and by extension the African culture, as regards the topic of sexuality. Moreover, it would enable the reader to fathom why the dominant African culture’s position on homosexuality is not a question of hatred but of culture clash.

description: One of the outcomes of the EC-FP7 project “Future Farm” was showing the need of INTEGRATION, something that PROGIS has been doing for 15 years. Within the whole sector agriculture–forestry-environment-risk management there is an enormous need for integration that is not available yet, because of on side the existing admin-sector-structures plus on the other side diverse public and/or private interests with opposite directions and in many cases the not streamlined interest of ALL involved parties. On the other hand we have the nature that is fully integrated and should be managed by us! Nothing happens without being related to something else within the nature. We have to be more aware of this and have also to understand that ICT will be the driver of integration as data and based on it these information is necessary and urgently needed for public and for private structures. We can do it separately, doing things in parallel and multiple times with multiple costs and reduced results. The other option is to cooperate on an integrative model!

description: Мигрень и эпилепсия – неврологические заболевания, характеризирующиеся рядом общих черт: пароксизмальностью возникновения приступов, нормальным неврологическим статусом в межприступном периоде, положительным ответом на прием антиконвульсантов. Более того, мигрень и эпилепсия – коморбидные заболевания. Распространенность головных болей среди больных эпилепсией составляет 59% [6]. В особенности сильная связь наблюдалось между мигрень с аурой и эпилепсией. Наиболее часто у пациентов, страдающих эпилепсией, отмечаются мигренозные или «мигренеподобные» головные боли (8-26%) [24]. Эпилепсия повышает риск развития мигрени в 2,4 раза, а мигрень повышает риск развития эпилепсии в 4,1 раз [28].

description: Machine learning methods provide a general framework for automatically finding and representing the essential characteristics of simulation data. This task is particularly crucial in enhanced sampling simulations. There we seek a few generalized degrees of freedom, referred to as collective variables (CVs), to represent and drive the sampling of the free energy landscape. In theory, these CVs should separate different metastable states and correspond to the slow degrees of freedom of the studied physical process. To this aim, we propose a new method that we call multiscale reweighted stochastic embedding (MRSE). Our work builds upon a parametric version of stochastic neighbor embedding. The technique automatically learns CVs that map a high-dimensional feature space to a low-dimensional latent space via a deep neural network. We introduce several new advancements to stochastic neighbor embedding methods that make MRSE especially suitable for enhanced sampling simulations: (1) weight-tempered random sampling as a landmark selection scheme to obtain training data sets that strike a balance between equilibrium representation and capturing important metastable states lying higher in free energy; (2) a multiscale representation of the high-dimensional feature space via a Gaussian mixture probability model; and (3) a reweighting procedure to account for training data from a biased probability distribution. We show that MRSE constructs low-dimensional CVs that can correctly characterize the different metastable states in three model systems: the Müller-Brown potential, alanine dipeptide, and alanine tetrapeptide.

description: We derive an exact representation of the exchange-correlation energy within density functional theory (DFT) which spawns a class of approximations leading to correct long-range asymptotic behavior. In what amounts to be the simplest approximation, we obtain an electronic structure theory that combines a new local correlation en-ergy (based on Monte-Carlo calculations applied to the homogeneous electron gas (HEG)) and a combination of local and explicit long-ranged exchange. The theory is applied to several 1st row atoms and diatomic molecules where encouraging results are obtained: a good description of the chemical bond at the same time allowing for bound anions, reasonably accurate affinity energies and correct polarizability of an elongated hydrogen chain. Further stringent tests of DFT are passed: the ratio of ionization potential and highest orbital energy is close to unity and the atomic charge of two distant hydrogen atoms under large bias is quantized (integer).

description: The scattering matrix was measured for a flat microwave cavity with classically chaotic dynamics. The system can be perturbed by small changes of the geometry. We define the "scattering fidelity" in terms of parametric correlation functions of scattering matrix elements. In chaotic systems and for weak coupling the scattering fidelity approaches the fidelity of the closed system. Without free parameters the experimental results agree with random matrix theory in a wide range of perturbation strengths, reaching from the perturbative to the Fermi golden rule regime.
