description: Retrospective emotional frequency appraisals are often used in clinical assessment measures, but their suitability for use with children has not been well studied. The aims of this project were to (a) examine whether items that use retrospective frequency structures gather more or less information than items that do not use such structures and (b) examine whether the information gathered by such items differs across children's ages. Method. Data were gathered from 9- to 12-year-old girls who participated in a larger study of a depression treatment protocol. Two sets of five pairs of items were sampled from two children's depression measures. The item pairs contained one item from each measure. One set of item pairs was matched for content and the use of retrospective frequency structures. The other set was matched for content only. Results. For the first research question, information curves for the two item sets were generated using Samejima's (1969) Graded Response Model (GRM). Visual analyses of the information curves provided inconclusive results as to whether the presence of retrospective frequency structures is associated with differences in item information levels. The second research question was conducted in two parts. For both, only data from the 9- and 12-year-old participants were analyzed. In the first part, confirmatory factor analysis was used to analyze measurement invariance across the two groups' responses. Theses analyses showed signs of measurement non-invariance in both item sets. The second part of the analyses was conducted by generating separate GRM information curves for the two age groups and conducting visual analyses of the information curves. These analyses showed that the model which had been used throughout the remainder of the study did not fit the 9-year-old group well. They also showed that the 12-year-old group's information curves varied more in height across measures and item sets than did the 9-year-old group's curves. Discussion. Although the findings failed to shed light on the effects of retrospective frequency structures on children's responding, they highlighted potential differences between the 9- and 12-year-old groups' factor structures and indicated that the 9-year-olds displayed decreased sensitivity to differences in item structure.

description: We survey fluorescent H2 emission in HST/STIS spectra of the classical T Tauri stars (CTTSs) TW Hya, DF Tau, RU Lupi, T Tau, and DG Tau, and the weak-lined T Tauri star (WTTS) V836 Tau. From each of those sources we detect between 41-209 narrow H2 emission lines, most of which are pumped by strong Ly-alpha emission. H2 emission is not detected from the WTTS V410 Tau. The fluorescent H2 emission appears to be common to circumstellar environments around all CTTSs, but high spectral and spatial resolution STIS observations reveal diverse phenomenon. Blueshifted H2 emission detected from RU Lupi, T Tau, and DG Tau is consistent with an origin in an outflow. The H2 emission from TW Hya, DF Tau, and V836 Tau is centered at the radial velocity of the star and is consistent with an origin in a warm disk surface. The H2 lines from RU Lupi, DF Tau, and T Tau also have excess blueshifted H2 emission that extends to as much as -100 km/s. The strength of this blueshifted component from DF Tau and T Tau depends on the upper level of the transition. In all cases, the small aperture and attenuation of H2 emission by stellar winds restricts the H2 emission to be formed close to the star. The Ly-alpha and the H2 emission blueshifted by 15 km/s relative to RU Lupi are extended to the SW by 0.07 arcsec, although the faster H2 gas that extends to about 100 km/s is not spatially extended. We also find a small reservoir of H2 emission from TW Hya and DF Tau consistent with an excitation temperature of about 2.5x10^4 K.

description: We study two aspects of the loop group formulation for isometric immersions with flat normal bundle of space forms. The first aspect is to examine the loop group maps along different ranges of the loop parameter. This leads to various equivalences between global isometric immersion problems among different space forms and pseudo-Riemannian space forms. As a corollary, we obtain a non-immersibility theorem for spheres into certain pseudo-Riemannian spheres and hyperbolic spaces. The second aspect pursued is to clarify the relationship between the loop group formulation of isometric immersions of space forms and that of pluriharmonic maps into symmetric spaces. We show that the objects in the first class are, in the real analytic case, extended pluriharmonic maps into certain symmetric spaces which satisfy an extra reality condition along a totally real submanifold. We show how to construct such pluriharmonic maps for general symmetric spaces from curved flats, using a generalised DPW method.

description: In this work we describe an approach to protecting the privacy and security of user data on mobile devices using a richer semantic model of a user's context. Mobile OS frameworks like Android always lacked mechanisms for dynamic privacy control, while recent advances in context modeling, tracking and collaborative localization has led to the emergence of a new class of smartphone applications that can access and share embedded sensor data. Existing literature on context based privacy and security has predominantly focused on device user's context for probing privacy vulnerability and enforcing security at runtime. We bring into picture the most important component of privacy vulnerability on smartphones, the resident applications themselves and we introduce the novel idea of application provenance. Our context model is realized as a dynamic knowledge base of RDF [67] triples grounded in an ontology in the semantic web language OWL. Policies in the form of rules over this knowledge base monitor and control application access to sensitive information and sensor data. The policies filter data flowing from sensor resources to applications to reduce disclosure by generalizing or obfuscating data. Our ontology includes the ability to represent application provenance and other metadata that can be used by the policies. The resulting system provides fine-grained, context-dependent control to sensitive user data.

description: Pebble accretion is one of the major theories in planet formation. Aerodynamically small particles, called pebbles, are highly affected by the gas flow. A growing planet embedded in a protoplanetary disk induces three-dimensional (3D) gas flow. In our previous study, Paper I, we focused on the shear regime of pebble accretion, and investigated the influence of planet-induced gas flow on pebble accretion. In Paper I, we found that pebble accretion is inefficient in the planet-induced gas flow compared to that in the unperturbed flow, in particular when ${\rm St}\lesssim10^{-3}$, where St is the Stokes number. Following Paper I, we investigate the influence of planet-induced gas flow on pebble accretion. We consider the headwind of the gas, which is not included in Paper I. We extend our study to the headwind regime of pebble accretion in this study. Assuming a nonisothermal, inviscid sub-Keplerian gas disk, we perform 3D hydrodynamical simulations on the spherical polar grid which has a planet with the dimensionless mass, $m=R_{\rm Bondi}/H$, located at its center, where $R_{\rm Bondi}$ and $H$ are the Bondi radius and the disk scale height. We then numerically integrate the equation of motion of pebbles in 3D using hydrodynamical simulation data. Combining our results with the spacial variety of turbulence strength and pebble size in a disk, we conclude that the planet-induced gas flow still allows for pebble accretion in the early stage of planet formation. Suppression of pebble accretion due to the planet-induced gas flow occurs only in the late stage of planet formation, in particular in the inner region of the disk. This may be helpful to explain the distribution of exoplanets and the architecture of the Solar System, both of which have small inner and large outer planets.

description: We study the static phase structure of the ISS-KKLT model for moduli stabilisation and uplifting to a zero cosmological constant. Since the supersymmetry breaking sector and the moduli sector are only gravitationally coupled, we expect negligible quantum effects of the modulus upon the ISS sector, and the other way around. Under this assumption, we show that the ISS fields end up in the metastable vacua. The reason is not only that it is thermally favoured (second order phase transition) compared to the phase transition towards the supersymmetric vacua, but rather that the metastable vacua form before the supersymmetric ones. This nice feature is exclusively due to the presence of the KKLT sector. We also show that supergravity effects are negligible around the origin of the field space. Finally, we turn to the modulus sector and show that there is no destabilisation effect coming from the ISS sector.

description: Dance and music are two highly correlated artistic forms. Synthesizing dance motions has attracted much attention recently. Most previous works conduct music-to-dance synthesis via directly music to human skeleton keypoints mapping. Meanwhile, human choreographers design dance motions from music in a two-stage manner: they firstly devise multiple choreographic dance units (CAUs), each with a series of dance motions, and then arrange the CAU sequence according to the rhythm, melody and emotion of the music. Inspired by these, we systematically study such two-stage choreography approach and construct a dataset to incorporate such choreography knowledge. Based on the constructed dataset, we design a two-stage music-to-dance synthesis framework ChoreoNet to imitate human choreography procedure. Our framework firstly devises a CAU prediction model to learn the mapping relationship between music and CAU sequences. Afterwards, we devise a spatial-temporal inpainting model to convert the CAU sequence into continuous dance motions. Experimental results demonstrate that the proposed ChoreoNet outperforms baseline methods (0.622 in terms of CAU BLEU score and 1.59 in terms of user study score).

description: The thermal conductivity and shear viscosity of dense nuclear matter, along with the corresponding shear viscosity timescale of canonical neutron stars (NSs), are investigated, where the effect of Fermi surface depletion (i.e., the $Z$-factor effect) induced by the nucleon-nucleon correlation are taken into account. The factors which are responsible for the transport coefficients, including the equation of state for building the stellar structure, nucleon effective masses, in-medium cross sections, and the $Z$-factor at Fermi surfaces, are all calculated in the framework of the Brueckner theory. The Fermi surface depletion is found to enhance the transport coefficients by several times at high densities, which is more favorable to damping the gravitational-wave-driven $r$-mode instability of NSs. Yet, the onset of the $Z$-factor-quenched neutron triplet superfluidity provides the opposite effects, which can be much more significant than the above mentioned $Z$-factor effect itself. Therefore, different from the previous understanding, the nucleon shear viscosity is still smaller than the lepton one in the superfluid NS matter at low temperatures. Accordingly, the shear viscosity cannot stablize canonical NSs against $r$-mode oscillations even at quite low core temperatures $10^6$ K.

description: It has recently been pointed out that the mirror or twin Higgs model is more technically natural than the standard model, thus alleviating the ``little'' hierarchy problem. In this paper we generalise the analysis to models with an arbitrary number of isomorphic standard model sectors, and demonstrate that technical naturalness increases with the number of additional sectors. We consider two kinds of models. The first has $N$ standard model sectors symmetric under arbitrary permutations thereof. The second has $p$ left-chiral standard model sectors and $p$ right-chiral or mirror standard model sectors, with $p$-fold permutation symmetries within both and a discrete parity transformation interchanging left and right. In both kinds of models the lightest scalar has an invisible width fraction 1/N, which will provide an important means of experimentally testing this class of models.

description: We discuss theoretically the possibility of observing the bound states of the ηand η'(958) mesons in nuclei. We apply the NJL model to study the ηand η' meson properties at finite density and calculate the formation cross sections of the ηand η' bound states with the Green function method for (γ,p) reaction. We also discuss the experimental feasibility at photon facilities like SPring-8. The contributions due to the ωmeson production are also included to obtain the realistic (γ,p) spectra. We conclude that we can expect to observe resonance peaks in (γ,p) spectra for the formation of meson bound states and we can deduce new information on ηand η' properties at finite density. These observations are believed to be essential to know the possible mass shift of η' and deduce new information on the effective restoration of the U_A(1) anomaly in the nuclear medium.

description: The spread of infections, as in the coronavirus pandemic, leads to the desire to perform disinfection measures even in the presence of humans. UVC radiation is known for its strong antimicrobial effect, but it is also harmful to humans. Visible light, on the other hand, does not affect humans and laboratory experiments have already demonstrated that intense visible violet and blue light has a reducing effect on bacteria and viruses. This raises the question of whether the development of pathogen-reducing illumination is feasible for everyday applications. For this purpose, a lighting device with white and violet LEDs is set up to illuminate a work surface with 2,400 lux of white light and additionally with up to 2.5 mW/cm2 of violet light (405 nm). Staphylococci are evenly distributed on the work surface and the decrease in staphylococci concentration is observed over a period of 46 hours. In fact, the staphylococci concentration decreases, but with the white illumination, a 90% reduction occurs only after 34 hours; with the additional violet illumination the necessary irradiation time is shortened to approx. 3.5 hours. Increasing the violet component probably increases the disinfection effect, but the color impression moves further away from white and the low disinfection durations of UVC radiation can nevertheless not be achieved, even with very high violet emissions.

description: We present a first-order aggregation model on a group ring, and study its asymptotic dynamics. In a positive coupling strength regime, we show that the flow generated by the proposed model tends to an equilibrium manifold asymptotically. For this, we introduce a Lyapunov functional which is non-increasing along the flow, and using the temporal decay of the nonlinear functional and the LaSalle invariance principle, we show that the flow converges toward an equilibrium manifold asymptotically. We also show that the structure of an equilibrium manifold is strongly dependent on the structure of an underlying group.

The late Quaternary history of primary productivity in the subarctic east Pacific
Creators: name: McDonald, Darcy
Publisher: name: University of British Columbia
Year: 2009

description: Palaeoceanographic work in the subarctic northeast Pacific has previously been limited by the common presence of turbidites and by the relatively shallow CCD. ODP Site 887 is on the Patton Murray Rise, an elevated plateau which is largely isolated from these effects. This area is centered under the Alaska Gyre, a region characterized by the domal upwelling of nutrient-rich waters. Sections from Holes 887A and 887C were spliced into the 887B profile to obtain a continuous composite record. Although calcite is not continuously distributed throughout the drilled section, the benthic foram 6¹⁸O profile from this record closely reflects the global (SPECMAP) signal. Hence, based on 6¹⁸O data and on radiocarbon dates from site survey cores,* a detailed chronology spanning the past 750 ky was developed. The controls on productivity in this region remain unclear since nitrate is perennially present in excess and does not limit primary production. However, past increases in productivity and rapid settling of biogenic matter are suggested by the episodic accumulation of diatomaceous oozes, and by high-resolution Si/Al, Ba/Al, C¹³org, and CaC0₃ profiles. Moreover, episodic shoaling of the redox boundary produced by increased organic matter flux to the seafloor, as during the deposition of the diatomaceous oozes, is suggested by trace metal and Mn enrichments. Significant 6¹³Corg maxima in the major diatomaceous bands suggest that productivity events have occurred which were sufficient to draw down mixed-layer PCO₂. Thus, in contrast to the near-neutral ocean-atmosphere PCO₂ gradient which exists today, an episodic sink for atmospheric CO₂ may have existed in the Gulf of Alaska in the past. Surface water temperature and salinity effects are evident in negative regional surface water 6¹⁸O variations. The episodes of enhanced productivity at Site 887 occur synchronously with such 6¹⁸Olocal excursions, suggesting a direct link to low salinity and/or warming events in the Gulf of Alaska which occur on sub- Milankovitch timescales. This suggests that significant climate variability in the Gulf of Alaska has been superposed on glacial-interglacial cycles through the Brunhes Chron. Temporal variations in the availability of iron may also have played a key role in constraining export production through time. Episodic input of iron, which may have stimulated productivity, may have occurred from either Asian sources via the atmosphere or more local sources via meltwater input.

description: Fire blight is a serious bacterial disease of apples, pears, quinces, and several plants in the rose family (Rosaceae), including hawthorn, cotoneaster, firethom (pyracantha), mountain ash, blackberry, and raspberry. Outbreaks of this disease are usually most severe in areas with a warm, humid climate, especially when these conditions occur during the bloom period of the tree or plant involved. This publication is aimed especially at growers of apples and pears, as many varieties and rootstocks of these fruit are very susceptible to the disease. This bulletin serves as a practical guide for the recognition of conditions conducive to disease development, identification of symptoms, prevention of disease development, and control of fire blight, including disease prediction. Key references are included for additional information on different aspects of fire blight.

In a similar way we also study the (gamma p --> K^0 pi^+ Lambda), (K^+ pi^- Sigma^+), (K^+ pi^+ Sigma^-), (K^0 pi^0 Sigma^+), and (eta pi^0 p) related reactions. The cross sections are proportional to the square of the coupling of Delta^*(1700) to (Sigma^*K), (Delta eta) for which there is no experimental information but which is provided in the context of coupled channels chiral unitary theory where the Delta^*(1700) is dynamically generated. Within present theoretical and experimental uncertainties one can claim a global qualitative agreement between theory and experiment. We provide a list of items which need to be improved in order to make further progress along these lines.

Analysis of Effects of Power Supply Noise on Propagation Delay

description: Today's very deep sub-micron technologies enable highly complex chip designs that operate at very high frequencies. Transistor dimensions have shrunk to a few tens of nanometers. Therefore, to ensure reliable chip operation and to reduce both dynamic and static power consumption the chip's supply voltage must be scaled down. This scaling of the maximum supply voltage reduces noise margins and makes designs susceptible to power supply noise. Power supply noise is the variation in the chip power supply i.e. IR and $Ldi/dt$ drops due to the power grid and package parasitics. As the supply voltage drops it causes an increase in the propagation delay. Transition-fault testing is a widely used test technique in the industry that can detect delay defects. In order to minimize the testing overhead, ATPG tools generate vectors that target multiple faults at the same time. However, these vectors cause excessive switching in the circuit and therefore increase power supply noise. As the propagation delay increases with power supply noise this can lead to a significant overkill when using transition test patterns. In order to accurately measure this noise one would need to run dynamic circuit simulations, which is infeasible even for a small portion of the chip. Previous work has demonstrated a convolution-based technique that can be used to compute transient current and voltage at the power pads and at different locations on the power grid. In this work, we use this computation technique to analyze the effect of power supply noise on path propagation delay. We also compare the delays computed using the convolution based technique to full-chip transient simulations.

representativeness

description: GLOBE is a global correlation engine, a project to study the effects on Land Change based on a set of parameters that include temperature, forest cover, human population, atmospheric parameters and many other variables. The aim of this research is to understand, how a study or a set of studies of specific geographic areas is representative of other areas of the world. The generic form of the question is, given a set of data points with a set of variables, how to determine how much a selected subset of points represents the rest of the distribution. The research aims to answer a set of questions which include the definition of representativeness of a geographical site and how the representativeness can be computed. Researchers studying land change will dynamically select a subset of variables which they would like to study. Hence the method developed not only computes representativeness, but does so in an efficient manner. For this purpose, we apply dimension reduction techniques to reduce the size of computation and analyze the effectiveness of using these techniques to calculate representativeness.

description: The results of a near-infrared (J H K LP) imaging linear polarimetry survey of 20 young stellar objects (YSOs) in rho Ophiuchi are presented. The majority of the sources are unresolved, with K-band polarizations, P_K < 6 per cent. Several objects are associated with extended reflection nebulae. These objects have centrosymmetric vector patterns with polarization discs over their cores; maximum polarizations of P_K > 20 per cent are seen over their envelopes. Correlations are observed between the degree of core polarization and the evolutionary status inferred from the spectral energy distribution. K-band core polarizations >6 per cent are only observed in Class I YSOs. A 3D Monte Carlo model with oblate grains aligned with a magnetic field is used to investigate the flux distributions and polarization structures of three of the rho Oph YSOs with extended nebulae. A rho proportional to r^(-1.5) power law for the density is applied throughout the envelopes. The large-scale centrosymmetric polarization structures are due to scattering. However, the polarization structure in the bright core of the nebula appears to require dichroic extinction by aligned non-spherical dust grains. The position angle indicates a toroidal magnetic field in the inner part of the envelope. Since the measured polarizations attributed to dichroic extinction are usually <10 per cent, the grains must either be nearly spherical or very weakly aligned. The higher polarizations observed in the outer parts of the reflection nebulae require that the dust grains responsible for scattering have maximum grain sizes <=1.05 microns.

description: В методике, как и в других науках, достоверность выводов и надежность рекомендаций обеспечиваются методами исследования. В их основе лежит диалектика, определяющая методологию науки (методология -учение о методах познания и преобразования действительности). Трудность исследований в методике русского языка, как и в педагогике, состоит в том, что сам исследуемый предмет, как правило, не удается вычленить из многогранных связей и влияний и взять его в чистом виде. Влияние побочных факторов бывает очень сильно и нередко искажает результаты исследования

description: We consider the connection between two constructions of the mirror partner for the Calabi-Yau orbifold. This orbifold is defined as a quotient by some suitable subgroup $G$ of the phase symmetries of the hypersurface $ X_M $ in the weighted projective space, cut out by a quasi-homogeneous polynomial $W_M$. The first, Berglund-Hübsch-Krawitz (BHK) construction, uses another weighted projective space and the quotient of a new hypersurface $X_{M^T}$ inside it by some dual group $G^T$. In the second, Batyrev construction, the mirror partner is constructed as a hypersurface in the toric variety defined by the reflexive polytope dual to the polytope associated with the original Calabi-Yau orbifold. We give a simple evidence of the equivalence of these two constructions.

THE RELATION BETWEEN PERCEIVED STRESS AND ANXIETY IN PREDICTING RELAPSE VULNERABILITY IN A DRUG ABUSING SAMPLE.

description: Despite significant advances in the understanding substance use disorders, they remain hard disorders to treat. Research suggests that individuals who struggle with abstinence or endorse more temptation to use are more vulnerable to relapse. The present study evaluated whether perceived stress and anxiety predict indicators of relapse vulnerability, temptations to use and reported struggle to maintain abstinence in a drug abusing sample. To address these aims, this project utilized data from the STOP Project, a multisite study which evaluated how baseline measures of motivation predicted treatment outcomes in a sample of treatment seeking drug abusing individuals. A significant positive linear relation between anxiety and the struggle to maintain abstinence was identified.  Additionally, a significant linear relation between perceived stress and temptation to use was found.  These findings have important implications on the role of negative affect in the relapse process and tailoring relapse prevention strategies to specific relapse vulnerability indicators.
Automatic Detection of Adrenal Gland Abnormality using the Random Forest Classification Framework combined with Histogram Analysis

description: Despite the fact that PACS (Picture Archiving and Communication Systems) has been available commercially for more than 15 years, few decision support tools exist for routine image interpretation.  We believe that characterization of adrenal abnormality is an excellent candidate for such a decision support tool. Adrenal abnormalities are commonly identified on CT (Computed Tomography) and are seen in at least 5% of CT examinations of the thorax and abdomen.  Previous studies have suggested that evaluation of Hounsfield units within a region of interest or a histogram analysis of a region of interest can be used to determine the likelihood that an adrenal gland contains an adenoma. However, the selection of a ROI (Region of Interest) can be arbitrary and operator dependent. We hypothesize that segmenting the entire adrenal gland automatically without any human intervention and then performing a histogram analysis to detect adrenal abnormality can not only improve accuracy but can also be achieved without any additional work or time demands on the radiologist. Three techniques are evaluated to perform automatic segmentation of the adrenal glands which include the GVF (Gradient Vector Flow) Snake approach, Random Regression Forest approach and the Random Classification Forest approach. We finally use the Random Classification Forest framework to automatically perform a pixel-wise classification of an entire CT volume into three classes namely right adrenal, left adrenal and background. Once we obtain this classification we then perform histogram analysis to detect adrenal abnormality.
GEI-16 : a novel component of the C. elegans fibrous organelle

description: Animal tissues are maintained by the correct cell-cell contacts and cellular shape. Cell shape and associations are governed by the combined action of the filament cytoskeleton in association with adhesion complexes. Desmosomes and hemidesmosomes are one such class of adhesion complex. From worms to humans epithelial tissues are flattened and made resistant to mechanical stress by desmosomes and hemidesmosomes. These membrane-associated junction complexes are attached to the intermediate filaments (IFs), the strongest and most elastic of the cytoskeletal filaments. In Caenorhabditis elegans, a requirement for the hemidesmosomes first becomes apparent in embryonic morphogenesis. Without functioning hemidesmosomes elongation arrests at the two-fold stage and the embryo never attains its vermiform shape (four-fold elongation). Characterisation of the loss of larva-specific intermediate filaments has shown that functional hemidesmosomes are necessary for tissue integrity and the continued development of the worm at all stages. It appears that, as in other animals, hemidesmosomes maintain a squamified epithelium which resists and equalises shearing forces generated during morphogenetic and locomotive movement. This thesis discusses the discovery of GEI-16 (PAT-12), a new component of the hemidesmosome and fibrous organelle (FO) in C. elegans. Discovered in a screen for uncharacterised, pan-nematode genes with vital functions, GEI-16 is necessary for all life stages. Loss of gei-16 leads to paralysis, muscle detachment and developmental arrest during the elongation step of embryogenesis. The same phenotype occurs in all stages of development if gei-16 is lacking. GEI-16 is likely to function with VAB-10 and the actin cytoskeleton to organise and strengthen the fibrous organelle during elongation.
Geochemical behaviour, fate and impacts of Cu, Cd and Zn from mine effluent discharges in Howe Sound
Creators: name: Chretien, Andre Remy Nicolas
Publisher: name: University of British Columbia

description: The now abandoned mine at Britannia Beach is a source of acidity and heavy metals to Howe Sound. Using evidence from monthly field sample collections over an entire year, the dispersion patterns of Cu, Cd and Zn in the estuary were elucidated. Acid mine drainage discharged to Howe Sound via Britannia Creek was found to mix predominantly with the brackish surface waters, since a pronounced pycnocline inhibits vertical mixing. Deep discharges via a submarine outfall may become trapped at or below ten metres depth during summer, but have been observed to rise to the surface in winter as a result of weaker stratification. Upon mixing with estuarine water, there was generally a transfer of Cu from the dissolved to the particulate phase. Similar removal was observed with Zn, albeit to a much lesser degree. Cd behaved essentially as a conservative element, which permitted its use as a tracer for the mixing of acid mine drainage with seawater. This greatly facilitated interpretation of the field data, since salinity proved to be an unreliable indicator of mixing in this three end-member system of Squamish River, Britannia Creek and seawater. Laboratory mixing experiments demonstrated that the removal of Zn occurred via adsorption onto iron oxyhydroxides, with other processes such as adsorption by flocculated organic matter or by clays playing a less important role. Cu removal was additionally governed to a large extent by direct precipitation of solid phases, most likely Cu(OH)2. Mixing experiments and speciation calculations suggest that Cu, and possibly Zn, may be present to a large degree in colloidal suspension. Metal concentrations in estuarine surface waters ranged between 0.8 - 230, 0.02 - 2.9 and 1.7 - 450 μg/L for Cu, Cd and Zn, respectively at a site some 350 m off the mouth of Britannia Creek. They were found to be controlled by the supply from acid mine drainage, by dilution with Squamish River runoff, and by the extent of removal in the creek mixing zone. All these parameters are strongly seasonal due to their dependence on hydrological conditions. They combined to produce maximum surface metal concentrations in spring and winter, as demonstrated using both field data and model calculations. In a bioassay experiment, Cu concentrations over 6.4 μg/L affected growth of endemic phytoplankton adversely. This level was found to be exceeded in 13 out of 26 field observations in Britannia Bay. In spring, concentrations that could produce detrimental effects on phytoplankton may also extend several kilometres down-estuary.
