description: The I-Love-Q relations are approximate equation-of-state independent relations that connect the moment of inertia, the spin-induced quadrupole moment, and the tidal deformability of neutron stars. In this paper, we study the I-Love-Q relations for superfluid neutron stars for a general relativistic two-fluid model: one fluid being the neutron superfluid and the other a conglomerate of all charged components. We study to what extent the two-fluid dynamics might affect the robustness of the I-Love-Q relations by using a simple two-component polytropic model and a relativistic mean field model with entrainment for the equation-of-state. Our results depend crucially on the spin ratio $Ω_{\rm n}/Ω_{\rm p}$ between the angular velocities of the neutron superfluid and the normal component. We find that the I-Love-Q relations can still be satisfied to high accuracy for superfluid neutron stars as long as the two fluids are nearly co-rotating $Ω_{\rm n}/Ω_{\rm p} \approx 1$. However, the deviations from the I-Love-Q relations increase as the spin ratio deviates from unity. In particular, the deviation of the Q-Love relation can be as large as $O(10\%)$ if $Ω_{\rm n}/Ω_{\rm p}$ differ from unity by a few tens of percent. As $Ω_{\rm n}/Ω_{\rm p} \approx 1$ is expected for realistic neutron stars, our results suggest that the two-fluid dynamics should not affect the accuracy of any gravitational waveform models for neutron star binaries that employ the relation to connect the spin-induced quadrupole moment and the tidal deformability.

Teaching francophone culture to core French students in an extended program : a curriculum proposal
Creators: name: Gudmundseth, Carole L.
Publisher: name: University of British Columbia
Year: 2010

description: A curriculum is proposed for teaching francophone culture to French core program students. Culture is inextricably linked to language yet often is not taught. By offering a course in francophone culture as an elective, high school students have an opportunity to increase the intensity of time spent in French while adding depth to their knowledge of the target culture. Definitions of civilization, formal and "deep" culture and the importance of time spent in language instruction are discussed. Models for the selection of content such as those proposed by Nostrand (1967), Seelye (1974) and Brooks (1974) are given. Egan's theory of educational development (1979) is seen as an appropriate basis for relating selection of content to the needs of the adolescent learner. A "functional" rather than a "formal" approach (Stern, 1976) is perceived as the most effective in the teaching of culture. It is posited that extended programs offer a feasible alternative to immersion and core programs and that francophone culture is a suitable topic for such a program. The curriculum proposed is intended for high school students simultaneously enrolled in core French program classes and consists of three parts: 1. Quebec, past and present; 2. Diverse themes presented and researched by students; and 3. La Francophonie chez vous: investigations by students into the local francophone community. The goal of the course is to improve performance in French and to increase the student's knowledge and appreciation of francophone culture.

description: We compare theory and observations for fundamental RR Lyrae in the solar neighborhood and in both Oosterhoff type I (OoI) and type II (OoII) Galactic globular clusters (GGCs). The distribution of cluster RR_ab in the PA_V plane depends not only on the metal abundance, but also on the cluster Horizontal Branch (HB) morphology. On average the observed k_puls parameter, connecting the period to the visual amplitude, increases when moving from metal-poor to metal-rich GGCs. However, this parameter shows marginal changes among OoI clusters with intermediate to red HB types and iron abundances -1.8<= [Fe/H] <=-1.1, whereas its value decreases in OoII clusters with the bluer HB morphology. Moreover, at [Fe/H]=-1.7+-0.1 the OoI clusters present redder HB types and larger values than the OoII clusters. The RR_ab variables in Omega Cen and in the solar neighborhood further support the evidence that the spread in [Fe/H], at fixed k_puls, is of the order of +-0.5 dex. Synthetic HB simulations show that the PA_V plane can provide accurate cluster distance estimates. The RR_ab variables in OoI and in OoII clusters with very blue HB types obey a well-defined M_V(RR)-k_puls relation, while those in OoII clusters with moderately blue HB types present a zero-point that is ~0.05 mag brighter. Regarding field variables, we show that with [Fe/H]=> -1.0 a unique M_V(RR)-k_puls relation can be adopted, independently of the parent HB morphology. Current findings suggest that the PA_V distribution does not seem to be a robust diagnostic for the metal abundance of RR_ab variables. However, the same observables can be used to estimate the absolute magnitude of globular cluster and field RR_ab variables. We show that over the metallicity range -2.4<= [Fe/H] <= 0.0 the M_V(RR)-[Fe/H] relation shows a parabolic behavior.

description: Posted price mechanisms (PPM) constitute one of the predominant practices to price goods in online marketplaces and their revenue guarantees have been a central object of study in the last decade. We consider a basic setting where the buyers' valuations are independent and identically distributed and there is a single unit on sale. It is well-known that this setting is equivalent to the so-called i.i.d. prophet inequality, for which optimal guarantees are known and evaluate to 0.745 in general (equivalent to a PPM with dynamic prices) and $1 - 1/e \approx 0.632$ in the fixed threshold case (equivalent to a fixed price PPM). In this paper we consider an additional assumption, namely, that the underlying market is very large. This is modeled by first fixing a valuation distribution F and then making the number of buyers grow large, rather than considering the worst distribution for each possible market size. In this setting Kennedy and Kertz [Ann. Probab. 1991] breaks the 0.745 fraction achievable in general with a dynamic threshold policy. We prove that this large market benefit continue to hold when using fixed price PPMs, and show that the guarantee of 0.632 actually improves to 0.712. We then move to study the case of selling k identical units and we prove that the revenue gap of the fixed price PPM approaches $1-1/\sqrt{ 2kπ}$. As this bound is achievable without the large market assumption, we obtain the somewhat surprising result that the large market advantage vanishes as $k$ grows.

description: The most accepted scenario for the evolution of massive galaxies across cosmic time predicts a regulation based on the interplay between AGN feedback, which injects large amounts of energy in the host environment, and galaxy mergers, being able to trigger massive star formation events and accretion onto the supermassive black holes. Interacting systems hosting AGN are useful laboratories to get key insights into both phenomena. In this context, we present the analysis of the optical spectral properties of IRAS 20210+1121 (I20210), a merging system at $z = 0.056$. According to X-ray data, this object comprises two interacting galaxies, each hosting an obscured AGN. The optical spectra confirm the presence of AGN features in both galaxies. In particular, we are able to provide a Seyfert classification for I20210 North. The spectrum of I20120 South shows broad blueshifted components associated with the most intense emission lines that indicate the presence of an ionized outflow, for which we derive a maximum velocity of $\sim$2000 km s$^{-1}$, an extension of $\sim$2 kpc and a mass rate of $\sim$0.6 M$_\odot$ yr$^{-1}$. We also report the existence of an ionized nebular component with $v \sim 1000$ km s$^{-1}$ at $\sim$6.5 kpc Southwards of I20210 South, that can be interpreted as disrupted gas ejected from the host galaxy by the action of the outflow. I20120 therefore exhibits a double obscured AGN, with one of them showing evidence of ongoing events for AGN-powered outflows. Future spatially-resolved spectroscopy will allow to accurately map on the gas kinematics in this AGN pair and evaluate the impact of the outflow on both the interstellar medium and galaxy environment.

description: We present heyoka, a new, modern and general-purpose implementation of Taylor's integration method for the numerical solution of ordinary differential equations. Detailed numerical tests focused on difficult high-precision gravitational problems in astrodynamics and celestial mechanics show how our general-purpose integrator is competitive with and often superior to state-of-the-art specialised symplectic and non-symplectic integrators in both speed and accuracy. In particular, we show how Taylor methods are capable of satisfying Brouwer's law for the conservation of energy in long-term integrations of planetary systems over billions of dynamical timescales. We also show how close encounters are modelled accurately during simulations of the formation of the Kirkwood gaps and of Apophis' 2029 close encounter with the Earth (where heyoka surpasses the speed and accuracy of domain-specific methods). heyoka can be used from both C++ and Python, and it is publicly available as an open-source project.

description: The temperature dependences of AC magnetic susceptibility at different magnetic field amplitudes and frequencies are investigated for underdoped and overdoped R(1-x)Ca(x)Ba(2)Cu(3)O(7-delta)(R=Y; Gd and x=0; 0.2) polycrystalline samples. The activation energy, Ea, for thermally assisted flux flow (TAFF) in intergranular region is determined. It was established that a correlation exists between the intergranular critical current and flux pinning activation energy. In underdoped samples the intergranular current shows S-I-S behaviour and the activation energy is small, while in overdoped samples the intergranular current is changed to S-N-S type and the activation energy increases. 2D pancake vortices are characteristic of underdoped samples, while 3D vortex system exists in overdoped samples. In fact we demonstrate that Ca substitution not only increases carrier concentration, but improves intergranular activation energy for TAFF.

description: Current models predict that binary interactions are a major ingredient for the formation of bipolar planetary nebulae (PNe) and pre-planetary nebulae (PPNe). Despite years of radial velocity (RV) monitoring, the paucity of known binaries amongst the latter systems is insufficient to examine this relationship in detail. In this paper, we report on the discovery of a long period (P=2654$\pm$124 d) binary at the centre of the Galactic bipolar PPN, IRAS 08005-2356 (V510 Pup) determined from long-term spectroscopic and near-infrared time series data. The spectroscopic orbit is fit with an eccentricity of 0.36$\pm$0.05 that is similar to other long period post-AGB binaries. Time resolved H$α$ profiles reveal high-velocity outflows (jets) with de-projected velocities up to 231$_{-27}^{+31}$ km s$^{-1}$ seen at phases when the luminous primary is behind the jet. The outflow traced by H$α$ is likely produced via accretion onto a main sequence companion for which we calculate a mass of 0.63$\pm$0.13 M$_\odot$. This discovery is one of the first cases of a confirmed binary PPN and demonstrates the importance of high-resolution spectroscopic monitoring surveys on large telescopes in revealing binarity among these systems.

Finite size effects on surface excess quantities: application to crystal growth and surface melting of epitaxial layers

description: From a macroscopic point of view phase transitions as surface melting or two dimensional (2D) towards three dimensional (3D) growth mode (Stranski-Krastanov transition) can be described in terms of Gibbs excess quantity duly amended by size effects (since usual Gibbs excess quantities are only well defined for semi-infinite systems). The aim of this study is to consider such amended quantities to describe surface melting and Stranski-Krastanov transition of epitaxial layers. the so-introduced size effects allows us to predict the equilibrium thickness of the wetting layer of the Stranski-Krastanov growth mode and to describe and classify two different melting cases: the incomplete melting relayed by a first order transition and the continuous premelting relayed by continuous overheating

Cracking of mild steel in NaOH and caustic aluminate solutions
Creators: name: Sriram, Rajagopal
Publisher: name: University of British Columbia
Year: 2010

description: Stress corrosion cracking (SCC) of ASME SA 516 Grade 70 steel was studied in hot (92°C) NaOH solutions of different caustic concentrations, caustic aluminate solutions and an Industrial Bayer solution (IBS). The potential regimes of stress corrosion cracking susceptibility were assessed using the slow strain rate technique (SSRT). At anodic potentials, SCC tendency was most pronounced in the active-passive transion region. Under these conditions, the largest number of secondary cracks and highest apparent crack velocities were observed in the IBS. The inhibition of corrosion of steel in caustic solutions by the addition of alumina trihydrate was studied by using anodic polarisation tests, cyclic voltammetry, electron diffraction and energy dispersive X-ray spectroscopy (EDS) techniques. The results were consistent with the formation of an amorphous iron-aluminate film on the electrode surface. Fracture mechanics techniques were used to study the kinetics of stress corrosion crack propagation in caustic solutions of different concentrations ( 2, 4 and 8 mols/Kg NaOH), 4 mols/Kg NaOH + 1 mol/KG of alumina and IBS. Both stress intensity dependent (region I) and stress intensity independent (region II) behaviour were observed. Crack fractography was studied by scanning electron microscopy. The results suggested that cracking at anodic potentials appears to be consistent with the general principles of the film-rupture dissolution model and that the dissolution processes in the crack-tip region were under mixed activation-diffusion control.

description: Selective configuration control of plasmonic nanostructures using either top-down or bottom-up approaches has remained challenging in the field of active plasmonics. We demonstrate the realization of DNA-assembled reconfigurable plasmonic metamolecules, which can respond to a wide range of pH changes in a programmable manner. This programmability allows for selective reconfiguration of different plasmonic metamolecule species coexisting in solution through simple pH tuning. This approach enables discrimination of chiral plasmonic quasi-enantiomers and arbitrary tuning of chiroptical effects with unprecedented degrees of freedom. Our work outlines a new blueprint for implementation of advanced active plasmonic systems, in which individual structural species can be programmed to perform multiple tasks and functions in response to independent external stimuli.

description: Am Beispiel der Anthroposophie untersucht die Studie das Verhältnis von Esoterik und Antisemitismus. Als empirischer Hintergrund dienen anthroposophische Schriften aus drei Phasen: von Rudolf Steiner selbst, aus der anthroposophischen Tradition mit einem Fokus auf die völkische Bewegung und den Nationalsozialismus sowie anthroposophische Zeitschriften aus dem Jahr 2021. Dabei wird deutlich, dass zahlreiche Gemeinsamkeiten zwischen beiden Ideologien in struktureller, funktionaler und inhaltlicher Hinsicht bestehen. Ohnehin lässt sich die Reproduktion antisemitischer Mythen und Stereotype in allen untersuchten Zeiträumen in anthroposophischen Veröffentlichungen nachweisen. Dies legt die These nahe, dass Antisemitismus in der anthroposophischen Lehre bereits latent angelegt ist. Im Besonderen gilt dies für drei grundlegende Elemente der anthroposophischen Lehre: Steiners Evolutionslehre, den Antimaterialismus sowie den Karmaglauben. Deshalb wird argumentiert, dass die Anthroposophie nicht nur Verschwörungsmythen im Allgemeinen nahesteht, wie die einschlägige Forschung (etwa zu „conspirituality“) nahelegt, sondern im Speziellen dem Antisemitismus. Anschließend werden die Spezifika des anthroposophischen Antisemitismus herausgearbeitet. Charakteristisch sind seine ausgeprägte Aversion gegen den Materialismus und seine Begründung. Außerdem fügt er dem klassischen modernen Antisemitismus eine weitere spirituelle (Hierarchie-)Ebene jenseits der materiellen Wirklichkeit hinzu. Mit der karmischen Deutung der Shoah existiert zudem ein antisemitisches Motiv, das direkt auf esoterische Grundannahmen zurückgeht.

description: In this article, a chiral plasmonic hydrogen-sensing platform using palladium-based nanohelices is demonstrated. Such 3D chiral nanostructures fabricated by nanoglancing angle deposition exhibit strong circular dichroism both experimentally and theoretically. The chiroptical properties of the palladium nanohelices are altered upon hydrogen uptake and sensitively depend on the hydrogen concentration. Such properties are well suited for remote and spark-free hydrogen sensing in the flammable range. Hysteresis is reduced, when an increasing amount of gold is utilized in the palladium-gold hybrid helices. As a result, the linearity of the circular dichroism in response to hydrogen is significantly improved. The chiral plasmonic sensor scheme is of potential interest for hydrogen-sensing applications, where good linearity and high sensitivity are required.

description: We provide the exact generating function for semi-flexible and super-flexible interacting partially directed walks and also analyse the solution in detail. We demonstrate that while fully flexible walks have a collapse transition that is second order and obeys tricritical scaling, once positive stiffness is introduced the collapse transition becomes first order. This confirms a recent conjecture based on numerical results. We note that the addition of an horizontal force in either case does not affect the order of the transition. In the opposite case where stiffness is discouraged by the energy potential introduced, which we denote the super-flexible case, the transition also changes, though more subtly, with the crossover exponent remaining unmoved from the neutral case but the entropic exponents changing.

description: Recommender system plays a crucial role in modern E-commerce platform. Due to the lack of historical interactions between users and items, cold-start recommendation is a challenging problem. In order to alleviate the cold-start issue, most existing methods introduce content and contextual information as the auxiliary information. Nevertheless, these methods assume the recommended items behave steadily over time, while in a typical E-commerce scenario, items generally have very different performances throughout their life period. In such a situation, it would be beneficial to consider the long-term return from the item perspective, which is usually ignored in conventional methods. Reinforcement learning (RL) naturally fits such a long-term optimization problem, in which the recommender could identify high potential items, proactively allocate more user impressions to boost their growth, therefore improve the multi-period cumulative gains. Inspired by this idea, we model the process as a Partially Observable and Controllable Markov Decision Process (POC-MDP), and propose an actor-critic RL framework (RL-LTV) to incorporate the item lifetime values (LTV) into the recommendation. In RL-LTV, the critic studies historical trajectories of items and predict the future LTV of fresh item, while the actor suggests a score-based policy which maximizes the future LTV expectation. Scores suggested by the actor are then combined with classical ranking scores in a dual-rank framework, therefore the recommendation is balanced with the LTV consideration. Our method outperforms the strong live baseline with a relative improvement of 8.67% and 18.03% on IPV and GMV of cold-start items, on one of the largest E-commerce platform.

description: Sliding is one of the fundamental mechanical movements in machinery. In macroscopic systems, double-rack pinion machines employ gears to slide two linear tracks along opposite directions. In microscopic systems, kinesin-5 proteins crosslink and slide apart antiparallel microtubules, promoting spindle bipolarity and elongation during mitosis. Here we demonstrate an artificial nanoscopic analog, in which gold nanocrystals can mediate coordinated sliding of two antiparallel DNA origami filaments powered by DNA fuels. Stepwise and reversible sliding along opposite directions is in situ monitored and confirmed using fluorescence spectroscopy. A theoretical model including different energy transfer mechanisms is developed to understand the observed fluorescence dynamics. We further show that such sliding can also take place in the presence of multiple DNA sidelocks that are introduced to inhibit the relative movements. Our work enriches the toolbox of DNA-based nanomachinery, taking one step further toward the vision of molecular nanofactories.

description: In this paper, we propose the MIML (Multi-Instance Multi-Label learning) framework where an example is described by multiple instances and associated with multiple class labels. Compared to traditional learning frameworks, the MIML framework is more convenient and natural for representing complicated objects which have multiple semantic meanings. To learn from MIML examples, we propose the MimlBoost and MimlSvm algorithms based on a simple degeneration strategy, and experiments show that solving problems involving complicated objects with multiple semantic meanings in the MIML framework can lead to good performance. Considering that the degeneration process may lose information, we propose the D-MimlSvm algorithm which tackles MIML problems directly in a regularization framework. Moreover, we show that even when we do not have access to the real objects and thus cannot capture more information from real objects by using the MIML representation, MIML is still useful. We propose the InsDif and SubCod algorithms. InsDif works by transforming single-instances into the MIML representation for learning, while SubCod works by transforming single-label examples into the MIML representation for learning. Experiments show that in some tasks they are able to achieve better performance than learning the single-instances or single-label examples directly.

description: A selection of ultracool dwarfs are known to be radio active, with both gyrosynchrotron emission and the electron cyclotron maser instability being given as likely emission mechanisms. To explore whether ultracool dwarfs previously undetected at 8.5 GHz may be detectable at a lower frequency. We select a sample of fast rotating ultracool dwarfs with no detectable radio activity at 8.5 GHz, observing each of them at 4.9 GHz. From the 8 dwarfs in our sample, we detect emission from 2MASS J07464256+2000321, with a mean flux level of 286 $\pm$ 24 $μJy$. The light-curve of 2MASS J07464256+2000321, is dominated towards the end of the observation by a very bright, $\approx $100 % left circularly polarized burst during which the flux reached 2.4 mJy. The burst was preceded by a raise in the level of activity, with the average flux being $\approx$ 160 $μJy$ in the first hour of observation rising to $\approx$ 400 $μJy$ in the 40 minutes before the burst. During both periods, there is significant variability. The detection of 100% circular polarization in the emission at 4.9 GHz points towards the electron cyclotron maser as the emission mechanism. However, the observations at 4.9 GHz and 8.5 GHz were not simultaneous, thus the actual fraction of dwarfs capable of producing radio emission, as well as the fraction of those that show periodic pulsations is still unclear, as indeed are the relative roles played by the electron cyclotron maser instability versus gyrosynchrotron emission, therefore we cannot assert if the previous non-detection at 8.5 GHz was due to a cut-off in emission between 4.9 and 8.4 GHz, or due to long term variability.

description: The specificity and simplicity of the Watson-Crick base pair interactions make DNA one of the most versatile construction materials for creating nanoscale structures and devices. Among several DNA-based approaches, the DNA origami technique excels in programmable self-assembly of complex, arbitrary shaped structures with dimensions of hundreds of nanometers. Importantly, DNA origami can be used as templates for assembly of functional nanoscale components into three-dimensional structures with high precision and controlled stoichiometry. This is often beyond the reach of other nanofabrication techniques. In this Perspective, we highlight the capability of the DNA origami technique for realization of novel nanophotonic systems. First, we introduce the basic principles of designing and fabrication of DNA origami structures. Subsequently, we review recent advances of the DNA origami applications in nanoplasmonics, single-molecule and super-resolution fluorescent imaging, as well as hybrid photonic systems. We conclude by outlining the future prospects of the DNA origami technique for advanced nanophotonic systems with tailored functionalities.

description: Butseloglis montisalbani Freudenthal, 2004 (Fig. 4A–I)
Type locality. Montalb́an 1D (MP23).
Holotype. Departamento de las Ciencias de la Tierra, University of Zaragoza, MLB1D 1050, left M1.
Specimens and measurements from Montalb́an 1D. UCBL-FSL_218025 to 218033 and 218071, for measurements see Table 1 and Supplemental material, Appendix 2 (Fig. 4A–I).
Description of the new specimens from Montalb́an 1D. In upper molars, the anteroloph and posteroloph are free lingually and labially. The anterotrope and posterotrope are absent. The protocone is anterior to the metacone. DP 4s are triangular. Only the weak centroloph is visible in DP 4. P4s display an oval shape with a well-developed precentroloph. Both M1s and M2s are rectangular. The anteroloph of M1 is shorter than that of M2. The precentroloph and postcentroloph are present in M1 and M2. The precentroloph is always developed, but the postcentroloph is sometimes weak. There is a strong reduction in M3 posteriorly. The state of the centrolophs is the same as M1/M2. The metaloph bends posterolabially but the posteroloph remains free.
In lower molars, the anterotropid is absent. The anterolophid becomes longer through m1 to m3. The metalophid is free lingually and labially, curved posteriorly only in m1. The centrolophid is long and free, without the precentrotropid and postcentrotropid nearby. A very weak posterotropid is only present in a few m2s.
Remarks. Butseloglis montisalbani was originally described as the type species of Schizogliravus, itself a junior synonym of Butseloglis. This species was not found in St-Martin-de-Castillon C. The type materials from Montalb́an 1D have been fully described by Freudenthal (2004). The new specimens from Montalb́an 1D are characterized by two equally important centrolophs which are always present in the upper molars; the centrolophid is frequently present, but not well developed; the mesolophid is well developed together with a weakly developed posterotropid. Our specimens consequently show no significant difference with the population described by Freudenthal (2004).

description: Imagine a task in which a group of separated players aim to simulate a statistic that violates a Bell inequality. Given measurement choices the players shall announce an output based solely on the results of local operations -- which they can discuss before the separation -- on shared random data and shared copies of a so-called unit correlation. In the first part of this article we show that in such a setting the simulation of any bipartite correlation, not containing the possibility of signaling, can be made arbitrarily accurate by increasing the number of shared Popescu-Rohrlich (PR) boxes. This establishes the PR box as a simple asymptotic unit of bipartite nonlocality. In the second part we study whether this property extends to the multipartite case. More generally, we ask if it is possible for separated players to asymptotically reproduce any nonsignaling statistic by local operations on bipartite unit correlations. We find that non-adaptive strategies are limited by a constant accuracy and that arbitrary strategies on n resource correlations make a mistake with a probability greater or equal to c/n, for some constant c.

description: The Humphreys-Davidson (HD) limit sets the boundary between evolutionary channels of massive stars that either end their lives as red supergiants (RSGs) or as the hotter blue supergiants (BSGs) and Wolf-Rayet stars. Mixing in the envelopes of massive stars close to their Eddington limit is crucial for investigating the upper luminosity limit of the coolest supergiants. We study the effects of excess mixing in superadiabatic layers that are dominated by radiation pressure, and we critically investigate the effects of mixing and mass loss on the evolution of RSGs with log (Teff/K) < 3.68 - as a function of metallicity. Using MESA, we produce grids of massive star models at three metallicities: Galactic (Zsol), LMC (1/2 Zsol) and SMC (1/5 Zsol), with both high and low amounts of overshooting to study the upper luminosity limit of RSGs. We systematically study the effects of excess mixing in the superadiabatic layers of post-main sequence massive stars, overshooting above the hydrogen core and yellow supergiant (YSG) mass-loss rates on the fraction of core helium burning time spent as a RSG. We find that the excess mixing in the superadiabatic layers is stronger at lower metallicities, as it depends on the opacities in the hydrogen bump at log (Teff/K) ~ 4, which become more pronounced at lower metallicity. This shifts the cutoff luminosities to lower values at lower metallicities, thus balancing the first-order effect of mass loss. The opposing effects of mass loss and excess envelope mixing during post-main sequence evolution of stars with higher overshooting potentially results in a metallicity-independent upper luminosity limit.

The electrochemical production of ferrate ions from iron anodes in alkaline solutions
Creators: name: Tuffrey, Nigel Edwin
Publisher: name: University of British Columbia
Year: 2010

description: An investigation into the electrochemical production of ferrate ions by anodic dissolution of iron anodes in strong alkaline electrolytes has been carried out. The stability of ferrate ions in alkaline solutions and the dependence of the decomposition reaction on temperature, hydroxyl ion concentration and ferrate ion concentration were determined. The stability of ferrate ions is favoured by low temperatures and ferrate ion concentrations, and high hydroxyl ion concentrations. Particulate ferric hydroxide is catalytic to the ferrate decomposition reaction. An electrochemical cell was designed to measure the rate of ferrate production. Using this cell and other techniques the efficiency of ferrate production as a function of the quantity of charge passed, the superficial current density and the hydroxyl ion concentration wane determined. The efficiency of ferrate formation is low and declines gradually to zero as increasing quantities of charge are passed. The efficiency of ferrate formation is independent of the superficial current density but declines rapidly as the hydroxyl ion concentration is reduced. A limited quantity of ferrate can be produced from an anode. There are indications that periodic current reversal can prevent the steady decline in the ferrate production rate. The oxide or hydroxide layer which formed on the anode during electrolysis could not be positively identified. This layer was x-ray amorphous, thickened slowly and an outer layer dissolved or spalled as the layer grew. The anode behaviour was examined using potentiodynamic, potentiostatic and constant current techniques. Transient anode behaviour was observed during the period of ferrate formation. It is proposed that the rate of ferrate production and the decline in the efficiency of ferrate formation with increasing quantities of charge passed can be explained, by: 1) the involvement of the oxide or hydroxide layer on the anode in the ferrate formation mechanism, and 2) changes which occur in the chemical or physical properties of the anode layer during electrolysis.
