description: Latinas are one of the largest and fastest growing minority groups in the United States (U.S.) and are at risk for poor health outcomes due to stress. However, little is known about the buffering effects of social support on stress and health in Latinas. In this cross-sectional study, we applied a structural equation modeling (SEM) approach to examine stress, social support and health outcomes in urban Latinas who participated in a community survey. We conducted iterative development of conceptual and analytic models through exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and SEM. Four hypotheses were tested with SEM: 1) Higher levels of stress are associated with worse health outcomes; 2) Lower levels of social support are associated with worse health outcomes; 3) Being older or having lower levels of education is associated with worse health outcomes; and 4) Social support moderates the relationship between stress and health outcomes. The study sample comprised 2,035 Latinas who were predominantly immigrants from the Dominican Republic, had a mean age of 50; the majority reported low levels of chronic stress, lower than national average psychological distress scores, and rated their health as good or better. Levels of online social support were low – about 20%. The EFA rendered a three-factor solution with strong factor loadings: chronic stress, online social support, and health. The CFA models had adequate model fit indices. The hypotheses were not supported in the SEM. This is the first study to apply EFA and SEM approaches to develop and evaluate measurements of stress, social support, and health in a large sample of Latinas. Consequently, this research provides an important foundation for further examination of these constructs. This is an essential prerequisite to development of culturally appropriate social support interventions including those that are online for the rapidly growing U.S. Latina population.

description: We have developed a method to measure the electric field standing wave distributions in a microwave resonator using a scanned perturbation technique. Fast and reliable solutions to the Helmholtz equation (and to the Schrodinger equation for two dimensional systems) with arbitrarily-shaped boundaries are obtained. We use a pin perturbation to image primarily the microwave electric field amplitude, and we demonstrate the ability to image broken time-reversal symmetry standing wave patterns produced with a magnetized ferrite in the cavity. The whole cavity, including areas very close to the walls, can be imaged using this technique with high spatial resolution over a broad range of frequencies.

description: Inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold are investigated under dimensional reduction. In the Einstein conformal frame, small excitations of the scale factors of the internal spaces near minima of an effective potential have a form of massive scalar fields in the external space-time. Parameters of models which ensure minima of the effective potentials are obtained for particular cases and masses of gravitational excitons are estimated.

Year: 2016

description: Peer review of dams and tailings facilities has been done for a long time. Independent tailings facility review is, however, still not standard practice. This paper describes the authors’ stories of early peer review in which they were involved. Hence the paper surveys some early and current expert opinions on what constitutes reasonable tailings facility peer review. Finally the paper addresses some current issues facing those who convene or sit on Independent Tailings Review Boards. The opinions and recommendations in this paper are personal, probably controversial, and certainly not universally implemented.

description: In this thesis the effects of high temperatures on fermentation characteristics, as well as the use of thermotolerant yeasts in brewing are investigated. Specifically, the effects of high temperatures on yeast growth and fermentation rate are examined and the characteristics of the products produced at high temperature fermentations are analyzed. Signal transduction pathways involving reactive oxygen species as second messengers seem to participate in the decrease of yeast growth rate at supraoptimal temperatures, while ethanol, lactic acid and acetic acid are described as ‘escape valves’ for the yeast cells. Oxidative stress is linked to thermal stress. Furthermore, the effects of high fermentation temperatures on the production of volatile compounds during fermentation are overviewed. Esters’ and higher alcohols’ levels increase with the temperature and the promoted expression of specific genes which are involved in their production is the reason for that. Furthermore, diacetyl forms sharper peaks at high fermentation temperatures, which coincides with decreased maturation times. Acetaldehyde levels depend mainly on the availability of NADH and there is not a clear connection between their levels in beer and fermentation temperature. The brewing characteristics of several thermotolerant yeasts are analyzed. These yeasts come from the wine industry, the distilleries and bioethanol production sectors or from farmhouse ales, including Norwegian Kveik. Several Kveik yeasts have mutations at the CDC25 gene which has been found to increase thermotolerance. Novel products made with these yeasts are suggested and they include low alcohol beers with Brettanomyces, low alcohol beers and Lambics with Lachancea thermotolerans, hard seltzers with whisky strains and high gravity brewing with Kveik. The operational challenges and the benefits associated with high fermentation temperatures are stated. Thermotolerant yeasts can significantly decrease fermentation times and save at least 100,000 hL/year for a brewery with an annual production capacity of 5 million hL/year. Finally, a SWOT analysis is included for five of the articles that were used in this thesis to assess their quality, explore their strengths and weaknesses, and reveal their potential for new, more comprehensive, research projects. Most of the novel product ideas are contained in the SWOT analysis.

description: Deep neural networks (DNNs) have been shown to outperform conventional machine learning algorithms across a wide range of applications, e.g., image recognition, object detection, robotics, and natural language processing. However, the high computational complexity of DNNs often necessitates extremely fast and efficient hardware. The problem gets worse as the size of neural networks grows exponentially. As a result, customized hardware accelerators have been developed to accelerate DNN processing without sacrificing model accuracy. However, previous accelerator design studies have not fully considered the characteristics of the target applications, which may lead to sub-optimal architecture designs. On the other hand, new DNN models have been developed for better accuracy, but their compatibility with the underlying hardware accelerator is often overlooked. In this article, we propose an application-driven framework for architectural design space exploration of DNN accelerators. This framework is based on a hardware analytical model of individual DNN operations. It models the accelerator design task as a multi-dimensional optimization problem. We demonstrate that it can be efficaciously used in application-driven accelerator architecture design. Given a target DNN, the framework can generate efficient accelerator design solutions with optimized performance and area. Furthermore, we explore the opportunity to use the framework for accelerator configuration optimization under simultaneous diverse DNN applications. The framework is also capable of improving neural network models to best fit the underlying hardware resources.
Strong Readers’ Beginnings: Identifying the Agencies and Individuals Who Influence Reading Lives

description: While there exists substantial research on struggling and developmental readers, few research-practitioners have sought to examine the histories and circumstances that result in strong readers. This study drew upon the reading autobiographies of doctoral students in an English Education program at an Ivy League institution, in order to discover what can be learned from first-hand narrative accounts of their reading lives about the early literacy experiences, reading practices, family, community, school and cultural influences of a group of “strong” adult readers. Also examined for comparative and contrasting data are the reading lives of remedial and honors first-year college composition students at a 2-year community college. An understanding of how the environments, people, institutions, circumstances, and texts encountered in the literacy lives of the three different groups studied here can assist literacy educators in bridging theory with practice for the teaching of reading in early grades and for the teaching of college-level reading in first-year college writing classes. A central term and concept to help explain the trajectory of the reading lives of the populations studied here was Deborah Brandt’s (1998) theory of “sponsors of literacy.” Brandt’s terminology and the notion of sponsorship along with a sociocultural theoretical framework are used to interpret the reading autobiographies in this study. Methods employed were based on Connelly and Clandinin’s narrative inquiry approach, a methodology steeped in the richness of the storied lives of the participants. The three patterns that emerged in the strong readers’ memories were: (a) being read to in the home prior to school age; (b) dichotomous attitudes toward in-school and out-of-school reading, especially around the middle school years; and (c) evidence of firm productive habits of mind toward complex reading that extends into the higher education years. The early literacy sponsorship and productive habits of mind were less evidenced in the remedial population. The findings of certain common characteristics and practices in the backgrounds of strong readers, many of which were not present at the same level in the remedial readers, can help literacy educators and caregivers re-examine their role as literacy sponsors and offer approaches for how we might sponsor literacy differently to create strong readers at any stage of their education.

description: An abstract system of congruences describes a way of partitioning a space into finitely many pieces satisfying certain congruence relations. Examples of abstract systems of congruences include paradoxical decompositions and $n$-divisibility of actions. We consider the general question of when there are realizations of abstract systems of congruences satisfying various measurability constraints. We completely characterize which abstract systems of congruences can be realized by nonmeager Baire measurable pieces of the sphere under the action of rotations on the $2$-sphere. This answers a question of Wagon. We also construct Borel realizations of abstract systems of congruences for the action of $\mathsf{PSL}_2(\mathbb{Z})$ on $\mathsf{P}^1(\mathbb{R})$. The combinatorial underpinnings of our proof are certain types of decomposition of Borel graphs into paths. We also use these decompositions to obtain some results about measurable unfriendly colorings.

description: After early work of Henon it has become folk knowledge that symmetric periodic orbits are of particular importance. We reinforce this belief by additional studies and we further find that invariant closed symplectic submanifolds caused by discrete symmetries prove to be an important complement to the long known role of the orbits. The latter have particular importance in semi-classics. Based on the structural stability of hyperbolic horseshoes we give an argument that opens an avenue to the understanding of these facts.

description: This thesis seeks to contribute to the resilience of historic resources on the Jersey Shore by analyzing ways in which the New Jersey preservation community’s response to Superstorm Sandy can inform future plans for hazard mitigation and adaptation to climate change.  In order to accomplish this, this work attempts to identify the pre-existing conditions that influenced the ways in which preservationists responded to Superstorm Sandy, the strengths and weaknesses of preservation agencies’ responses, and how these can inform the ways in which heritage practitioners promote the resilience of historic resources in the face of climate change.  By compiling oral histories of preservationists working in the aftermath of Sandy, this thesis provides a comprehensive narrative for a previously untold story.  Additionally, this research aims to contribute to the growing body knowledge surrounding the incorporation of historic preservation into planning for both natural disasters and sea level rise. Taking the issues identified on the Jersey Shore and recognizing the opportunities for change, this thesis fills a gap in academic literature by discussing how preservationists can practically apply adaptation and mitigation measures.

description: The present study presents a novel method employing Near Infrared Spectroscopy (NIR) for detection of the use of calcium carbide in artificial ripening of mangoes. Use of calcium carbide has been banned in artificial ripening of fruits as it contains traces of arsenic. Mango samples were ripened artificially using calcium carbide and compared with naturally ripened mangoes using NIR spectroscopic wavelength ranging from 600 to 1100 nm. The captured NIR spectra from mango samples were analysed using multivariate methods including principal component analysis, particle least square and successive projection algorithm. The obtained results showed distinguishing zones for naturally and artificially ripened mangoes. Furthermore, the arsenic content was obtained through ICP-MS analysis, and it was found that mangoes ripened artificially using calcium carbide have a higher content of arsenic. Hence, arsenic was used as a principal component in the analysis. The developed method is not unique to samples that were grown in any particular region or year as it and can be used universally as NIR will give the distinguishing comparison between naturally- and artificially ripened mangoes. This method is simple, non-invasive, non-destructive and rapid for detection of use of calcium carbide in the artificial ripening of mangoes.

Subjects: Global cities, city-region, Milan, power elite, discourse analysis, urban governance, policy-making, cultural models.

description: This work concerns the role of the power elite in the processes of urban governance, through the analysis of the decision-making mechanisms related to the development of Milan at two levels: the overview of the local power elite structure and the identification of the shared representations of the development of Milan among its members. This can be done through a mixed methodology based on the positional, reputational, decisional and social network analysis of the power elites operating in Milan and the analysis of their discourse on Milan development, with the purpose of identifying the cultural models orienting their role in the shape of the policy-making process of governance of Milan. This kind of study aims to contribute to the debate and practices of urban governance, an issue of particular relevance in consideration of the need of a reform of territorial governance in Italy and of the emphasis on the city as a driving force for sustainable development and social cohesion in European discourse.

description: Reducing the number of non-Clifford quantum gates present in a circuit is an important task for efficiently implementing quantum computations, especially in the fault-tolerant regime. We present a new method for reducing the number of T-gates in a quantum circuit based on the ZX-calculus, which matches or beats previous approaches to T-count reduction on the majority of our benchmark circuits in the ancilla-free case, in some cases yielding up to 50% improvement. Our method begins by representing the quantum circuit as a ZX-diagram, a tensor network-like structure that can be transformed and simplified according to the rules of the ZX-calculus. We then show that a recently-proposed simplification strategy can be extended to reduce T-count using a new technique called phase teleportation. This technique allows non-Clifford phases to combine and cancel by propagating non-locally through a generic quantum circuit. Phase teleportation does not change the number or location of non-phase gates and the method also applies to arbitrary non-Clifford phase gates as well as gates with unknown phase parameters in parametrised circuits. Furthermore, the simplification strategy we use is powerful enough to validate equality of many circuits. In particular, we use it to show that our optimised circuits are indeed equal to the original ones. We have implemented the routines of this paper in the open-source library PyZX.

Publisher: name: The University of British Columbia
Year: 2017

description: If the State of Nevada were a country, it would rank as the eighth largest gold producer in the world (NMA, 2014). The state is also a significant producer of silver, copper, barite, lithium, and other minerals. Nevada currently has over 30 active tailings dams permitted through the Nevada Division of Water Resources (NDWR). A variety of conditions, including geology, seismicity, and climate present challenges to both the design and regulation of tailings dams in the state. This paper provides an overview of historic and current regulations and design practices by combining the authors’ experience with information from the NDWR’s Safety of Dams Program database to present a general overview of the tailings dams in Nevada. The goal of the paper is to familiarize mine owners, regulators, and tailings dam designers with regulations and general engineering concepts currently used in Nevada.

description: The Phytoplankton Reservoir Trophic Index (PRTI), based on the relative abundance of phytoplankton in reservoirs, was applied to 62 reservoirs, all in the territorial division of the Ebro River Basin, Spain. We compared the results of the PRTI to the Carlson Trophic State Index (TSI), based on the concentration of chlorophyll a in an integrated water sample through the photic depth. The PRTI allows assessment of the trophic status of different reservoirs based on phytoplankton densities from an aliquot of a vertically integrated sample. The occurrence of each phytoplankton species in relation to eutrophication was derived from a canonical correspondence analysis between the phytoplankton species and 8 physicochemical variables. The PRTI is used in this study to classify reservoirs into 5 ecological status categories according to the European Water Framework Directive. This methodology has been applied annually from 2006 to 2017 for ecological quality assessments of reservoirs in Spain. The PRTI seems to be a valid index to determine the trophic status of reservoirs and extends information beyond that reported in the TSI.

description: Die magnetooptischen (mo) Effekte, das sind Faraday- und mo Kerr-Effekt, sind bei stattfindender Vielfachreflexion in planparallelen Proben bzw. in entsprechend aufgebauten Schichtsystemen stets Überlagerungseffekte, denn die vielfachreflektierten Strahlanteile treten nach mehrfacher Transmission und mehrfacher Reflexion (unter Einschluß von Umkehrungen der Lichtausbreitungsrichtung!) zu einer einzigen Meßgröße in Transmission ("resultierender Faraday-Effekt") bzw. Reflexion ("resultierender mo Kerr-Effekt") zusammen. Dabei sind die kohärente und die inkohärente Überlagerung der Teilstrahlen zu unterscheiden. Teil I der Arbeit stellte ein "Iterationsverfahren" zur Berechnung der mo Effekte einer Planplatte vor. Im vorliegenden Teil II der Arbeit wird der "inkohärente Fall" dahingehend untersucht, ob ein Matrizenverfahren Anwendung finden kann, die mo Effekte zu berechnen. Die Ergebnisse hängen davon ab, welches Meßverfahren Anwendung findet: die Polarisationsanalyse mit Analysatordrehung ("AD-Methode") oder die getrennte bzw. in Modulation abwechselnde Intensitätsmessung für die rechts- bzw. links-zirkular polarisierte Eigenmode des Lichtes im Magnetfeld ("ZPM-Methode"). - Im ersten Fall ist eine Matrizenrechnung grundsätzlich nicht möglich. - Im zweiten Fall ist eine korrekte Matrizenrechnung für die in der Messung allein zugängliche mo Elliptizität jedoch gegeben. Eine Beispielrechnung stellt die grundsätzlich unterschiedlichen Elliptizitätsspektren bei der AD-Methode und der ZPM-Methode vergleichend gegenüber. - Für die mo Drehung bei der AD-Methode wird das Verfahren einer verbesserten Matrizen- Näherungsrechnung vorgestellt. Es liefert zugleich die mo Elliptizitätswerte der ZPM-Methode in Transmission und Reflexion. In einer Beispielrechnung wird dabei bezüglich Drehung und Elliptizität eine Näherungsgenauigkeit erreicht, die typischerweise besser ist als 0,02%. - Für ein Teilschichtsystem mit kohärenter Vielfachreflexion innerhalb ein Schichtsystems mit inkohärenter Vielfachreflexion wird eine "mo Ersatz-Grenzschichtmatrix" angegeben, mit deren Hilfe der Einbau des kohärenten Teilschichtsystems in die oben genannten Rechenverfahren möglich ist.

description: Glasfasern dämpfen optische Impulse so wenig, daß sie in heutigen Nachrichtennetzen die bis zu 2 Milliarden optischen Informations-Bits pro Sekunde aus Halbleiterlasern Hunderte von Kilometern ohne Regeneration übertragen. Wenn beim Empfang der optischen Impulse anstelle der direkten Umwandlung in elektrische Stromimpulse mit Überlagerungsempfang gearbeitet wird, darf die Faserstrecke zwischen Regeneratoren noch gut hundert Kilometer länger sein. Mit Glasfaserlasern als Zwischenverstärker können es sogar an die tausend Kilometer sein. Wenn die Faserkerne mit erhöhter Brechzahl ausgeführt und so verengt werden, daß sie bei den optischen Wellenlängen geringster Dämpfung die Signalimpulse auch nur noch minimal verzerren, können mit Faserzwischenverstärkern aber ohne Regeneratoren selbst die Tausende von Kilometern transkontinentaler und transozeanischer Verbindungen überbrückt werden. In Zukunft wird man mit schnellen optischen Schaltern bis zu 100 Milliarden Signalimpulse pro Sekunde erzeugen und sie als Glasfaser-Solitonen und mit Faserverstärkern über praktisch unbegrenzte Entfernungen übertragen können. Die Übertragungskapazität alleine läßt sich mit Wellenlängenmultiplex vervielfachen, bei dem viele optische Träger verschiedener Wellenlänge überlagert und in jeweils einer Faser gemeinsam übertragen werden.
Um in den Knotenpunkten zukünftiger Nachrichtennetze Informationsflüsse von vielen Billionen Bits pro Sekunde zu vermitteln, wird man das räumliche Schalten durch zeitliches Verschachteln und durch Verteilen der Signalflüsse auf viele optische Träger verschiedener Wellenlänge erweitern. Für diese optische Vermittlung ebenso wie auch für die Teilnehmeranschlüsse müssen integrierte photonische und optoelektronische Schaltungen, ähnlich wie die integrierten Schaltungen der Mikroelektronik, entwickelt werden. Insbesondere brauchen kostengünstige Teilnehmeranschlüsse eine integrierte Optoelektronik, die Verstärker, Laser, Photodetektoren und optische Sende-Empfangsduplexer auf einem winzigen Halbleiterchip zusammenfaßt.

description: This thesis builds the micro foundations of the first modern social movement: the movement for the abolition of the slave trade in the early 19th century British context. I derive theories of action from the historical literature, and use work from historical sociology and movement theory to understand the decision to petition for abolition. Two major empirical undertakings are employed to adjudicate between different theories of action accounting for abolitionist petitioning.
      First, zooming in on Manchester, I deploy the signatures of an abolitionist petition to find the social-structural drivers of abolitionist mobilization. Through a careful reconstruction of the city’s historic geography, I place over 10000 residents in physical space along with important buildings, such as churches, inns and taverns: focal points that provided the basis of associational life and early civil society, places where politics was done at the time. I delineate the limits of the impact of the Quaker congregation, and demonstrate that in fact these focal points induced the spatial-clustering of abolitionist petitioners. Furthermore, I reveal that economic interests are not among key drivers of abolitionist petitioning, as no clear occupational-gradient is found among petitioners. Besides the theoretical contributions, I use innovative ways to test which social relationships were crucial for petitioning.
      Second, zooming out on the national petitioning campaign I use self-collected data on petitions form the Journals of the British Parliament to study the movement at the macro level. The analysis shows that contact with the London-based central movement-organization was key for the success of the first campaign, but it also reveals that the second campaign relied more on "horizontal" connections rather than hierarchical ones tying provincial towns to London. Second, I confirm that non-conformist religious organizations were pivotal for the inception, and scaling of the national campaign, but the Quaker church seem to exert more important and continuous influence compared to the Wesleyan Methodist organization. Last but not least, I show that industrialization plays a key, and increasingly important role in the campaign for abolition.
Reduced phase space formalism for spherically symmetric geometry with a massive dust shell

description: We perform a Hamiltonian reduction of spherically symmetric Einstein gravity with a thin dust shell of positive rest mass. Three spatial topologies are considered: Euclidean (R^3), Kruskal (S^2 x R), and the spatial topology of a diametrically identified Kruskal (RP^3 - {a point at infinity}). For the Kruskal and RP^3 topologies the reduced phase space is four-dimensional, with one canonical pair associated with the shell and the other with the geometry; the latter pair disappears if one prescribes the value of the Schwarzschild mass at an asymptopia or at a throat. For the Euclidean topology the reduced phase space is necessarily two-dimensional, with only the canonical pair associated with the shell surviving. A time-reparametrization on a two-dimensional phase space is introduced and used to bring the shell Hamiltonians to a simpler (and known) form associated with the proper time of the shell. An alternative reparametrization yields a square-root Hamiltonian that generalizes the Hamiltonian of a test shell in Minkowski space with respect to Minkowski time. Quantization is briefly discussed. The discrete mass spectrum that characterizes natural minisuperspace quantizations of vacuum wormholes and RP^3-geons appears to persist as the geometrical part of the mass spectrum when the additional matter degree of freedom is added.

description: Attentional control represents a key component of information
processing. According to cognitive-behavioral models,
dysfunctional attentional processes (in the sense of attentional
biases) are involved in the development and maintenance
of almost all mental disorders. Attention modification
plays an essential role as a standard method of cognitivebehavioral
therapy. However, the empirical evidence concerning
the efficacy of various techniques of attention modification
is heterogeneous and has rarely been systematically
assessed in applied clinical/therapeutic contexts. This
article illustrates a multi-part attention modification with a
practical guideline, specific text samples, and difficulties.
Main elements of this technique include psychoeducation
on the functionality of attention processes, the planning
and realization of behavioral experiments, and the transfer
and self-management of attention control in the daily life of
the clients.

description: We present light curves and spectra of the tidal disruption event (TDE) ASASSN-18pg / AT 2018dyb spanning a period of one year. The event shows a plethora of strong emission lines, including the Balmer series, He II, He I and metal lines of O III $λ$3760 and N III $λλ$ 4100, 4640 (blended with He II). The latter lines are consistent with originating from the Bowen fluorescence mechanism. By analyzing literature spectra of past events, we conclude that these lines are common in TDEs. The spectral diversity of optical TDEs is thus larger than previously thought and includes N-rich events besides H- and He-rich events. We study how the spectral lines evolve with time, by means of their width, relative strength, and velocity offsets. The velocity width of the lines starts at $\sim$ 13000 km s$^{-1}$ and decreases with time. The ratio of He II to N III increases with time. The same is true for ASASSN-14li, which has a very similar spectrum to AT 2018dyb but its lines are narrower by a factor of $>$2. We estimate a black hole mass of $M_{\rm BH}$ = $3.3^{+5.0}_{-2.0}\times 10^6$ $M_{\odot}$ by using the $M$-$σ$ relation. This is consistent with the black hole mass derived using the MOSFiT transient fitting code. The detection of strong Bowen lines in the optical spectrum is an indirect proof for extreme ultraviolet and (reprocessed) X-ray radiation and favors an accretion origin for the TDE optical luminosity. A model where photons escape after multiple scatterings through a super-Eddington thick disk and its optically thick wind, viewed at an angle close to the disk plane, is consistent with the observations.
description: Accepted version. Updated with new photometry and spectra, including an X-shooter spectrum used to determine the BH mass. Two more figures added and line measurements tabulated. No significant scientific updates and the conclusions remain unaffected

description: Over the past ten years, the weathering mechanisms of waste rock at the Antamina Cu-Zn-Mo mine in Peru have been investigated. Recently a rotary vibratory drilling program was performed at two locations in the waste dump. The drill program presented a unique opportunity to gather mineralogical and geochemical information and to study the evolution of the alteration profile through time and depth associated with observed lithologies (e.g. skarns, intrusives, marbles, hornfels). The waste dump under investigation is approximately 400m tall with material that is highly heterogeneous in composition and grain size. A previous study showed that the reactivity of minerals vary with depth within the same borehole, because of variations in pore water chemistry and gas transport. The relationship between the variation in reactivity, the lithology, and the alteration profile is investigated in this study. The results provide information on the heterogeneity of the material in the waste dump. The observation of reactivity compared with lithology from the drill hole highlights the potential presence of complex geochemical mechanisms such as galvanic reaction and secondary mineral precipitation. The results will guide future research and demonstrate the contribution of weathering mechanisms on the long term release of metals from waste rock piles.
