CEREBRUM: Case-Enabled Reasoning Engine with Bayesian Representations for Unified Modeling
Creators: name: Friedman, Daniel Ari
Publisher: name: Active Inference Journal
Year: 2025

description: This paper introduces Case-Enabled Reasoning Engine with Bayesian Representations for Unified Modeling (CEREBRUM). CEREBRUM is a synthetic intelligence framework that integrates linguistic case systems with cognitive scientific principles to describe, design, and deploy generative models in an expressive fashion. By treating models as case-bearing entities that can play multiple contextual roles (e.g. like declinable nouns), CEREBRUM establishes a formal linguistic-type calculus for cognitive model use, relationships, and transformations. The CEREBRUM framework uses structures from category theory and modeling techniques related to the Free Energy Principle, in describing and utilizing model across. CEREBRUM addresses the growing complexity in computational and cognitive modeling systems (e.g. generative, decentralized, agentic intelligences), by providing structured representations of model ecosystems that align with lexical ergonomics, scientific principles, and operational processes.

description: The quest on how to collectively self-organize in order to maximize the survival chances of the members of a social group requires finding an optimal compromise between maximizing the well-being of an individual and that of the group. Here we develop a minimal model describing active individuals which consume or produce, and respond to a shared resource, such as the oxygen concentration for aerotactic bacteria or the temperature field for penguins, while urging for an optimal resource value. Notably, this model can be approximated by an attraction-repulsion model, but in general it features many-body interactions. While the former prevents some individuals from closely approaching the optimal value of the shared resource field, the collective many-body interactions induce aperiodic patterns, allowing the group to collectively self-optimize. Arguably, the proposed optimal-field-based collective interactions represent a generic concept at the interface of active matter physics, collective behavior, and microbiological chemotaxis. This concept might serve as a useful ingredient to optimize ensembles of synthetic active agents or to help unveiling aspects of the communication rules which certain social groups use to maximize their survival chances.

description: Because of Euler buckling, a simple strut of length $L$ and Young modulus $Y$ requires a volume of material proportional to $L^3 f^{1/2}$ in order to support a compressive force $F$, where $f=F/YL^2$ and $f\ll 1$. By taking into account both Euler and local buckling, we provide a hierarchical design for such a strut consisting of intersecting curved shells, which requires a volume of material proportional to the much smaller quantity $L^3 f\exp[2\sqrt{(\ln 3)(\ln f^{-1})}]$.

description: A Ansiedade na Performance Musical é definida como “a experiência de persistência, apreensão angustiante e/ou prejuízo real de habilidades de desempenho num contexto público, a um grau injustificado dado a aptidão musical individual, treinamento e nível de preparação do performer” (Salmon 1990). A partir de um ponto máximo de adaptação, a ansiedade, ao invés de contribuir, poderá resultar na diminuição da capacidade adaptativa, tornando se uma ameaça à qualidade de uma performance musical. Este trabalho pro pôs se realizar uma revisão da bibliografia existente sobre os questionários desenvolvidos para diagnóstico da ansiedade na performance musical e sobre sua epidemiologia. Foi aplicado o protocolo PRISMA (Moher et al. 2009) numa busca com palavras-chave em seis bases de dados. Os 26 artigos resultantes da aplicação dos critérios de seleção foram divididos em 6 categorias: (1) APM em crianças e adolescentes; (2) Epidemiologia da APM; (3) APM e validação de questionários; (4) APM em instrumentistas/cantores; (5) APM e gênero musical; (6) APM em orquestras/coros.

title: Establishment of Tall Wheatgrass [Agropyron elongatum (Host) Beav. 'Jose'] and Basin Wildrye (Elymus cinereus Scribn. & Merr. 'Magnar') in Relation to Soil Water and Salinity
Creators: name: Roundy, Bruce A.

description: The potential of basin wildrye (Elymus cinereus Scribn. & Merr. 'Magnar') and tall wheatgrass [Agropyron elongatum (Host) Beav. 'Jose '] to establish on saline, arid rangelands in the Great Basin in relation to soil water and salinity was compared in field and laboratory experiments. Tall wheatgrass had higher emergence and establishment on a nonsaline and a saline soil (electrical conductivity of the saturation extract of 7 dS·m-1) over a range of spring precipitation as simulated by sprinkler irrigation. Basin wildrye will require supplemental irrigation to establish on soils of similar salinity. In the absence of precipitation, soil salinity increases and matric and osmotic potentials rapidly decrease as the surface soil dries in late spring. Germination and growth responses in relation to salinity and drought in laboratory experiments were consistent with emergence and establishment results in the field experiments. Tall wheatgrass had higher total germination, rate of germination and radicle growth under decreasing osmotic potentials and higher emergence under decreasing matric potentials than basin wildrye. Tall wheatgrass had greater root and shoot yield than basin wildrye when osmotic potentials in sand cultures were decreased by solutions of NaCl, Na2SO4 and CaCl2.Tall wheatgrass is more tolerant of salt and boron than basin wildrye, but basin wildrye is highly salt tolerant compared to most forage species. Tall wheatgrass had more rapid root elongation and more extensive root growth than basin wildrye seedlings grown in 60-cm soil columns filled with nonsaline and saline soil. Germination and growth of both species was reduced by ions in addition to the effects of water stress due to low osmotic potentials. Rate of germination and radicle growth of both species was less in salts than in isosmotic polyethylene glycol solutions. Seedlings exhibited less growth in saline than nonsaline soil even when plant water stress was minimal or when leaf water potentials were low but turgor was maintained by osmotic adjustment. Germination at low osmotic and matric potentials and root elongation in relation to salinity may be important plant responses to use in evaluating the potential for establishment of new plant materials on saline, arid rangelands.

description: This study aimed to explore the possible indirect pathway between maternal reminiscing style and child socioemotional functioning (prosocial behaviors and emotional adjustment difficulties) through children’s autobiographical memory (elaboration and specificity). A secondary exploratory aim was to examine whether cultural context moderated these indirect effects. Participants included 94 mother-child dyads drawn from middle- and high-income families in China and Australia. The dyads completed measures of child memory specificity, maternal report of child socioemotional functioning, and a shared emotional reminiscing task that assessed child memory elaboration and maternal sensitive guidance. Path analysis results indicated an indirect effect of maternal supportive reminiscing via child memory elaboration (but not memory specificity) on children’s prosocial behaviors, regardless of the cultural group. However, there was no evidence to suggest an indirect pathway between maternal supportive reminiscing and child adjustment difficulties (or prosocial behaviors) through child memory specificity in either cultural context. These findings provide preliminary support to the recent conceptualization of an indirect pathway between maternal sensitive guidance during emotional reminiscing and children’s prosocial behaviors through child memory elaboration. However, it is important to note that the cross-sectional design limits the causal inferences that can be drawn from the findings. The implications for memory specificity in child socioemotional functioning were less clear and indicated a need for further research in this area.

description: A direct link between large-scale environment and galaxy properties is very well established in the local universe. However, very little is known about the role of the environment for galaxy growth before the peak of the cosmic star formation history at $z>3$ due to the rarity of high-redshift, overdense structures. Using a combination of deep, multiwalength observations, including MUSE, JWST, Chandra, HST and ground-based imaging, we detect and study the properties of a population of star-forming galaxies in the field of a hyperluminous quasar at $z\approx3.25$ associated with the giant Ly$α$ nebula MQN01. We find that this region hosts one of the largest overdensity of galaxies found so far at $z>3$, with $ρ/\barρ=53\pm17$ within $4\times4\rm\,cMpc^2$ and $|Δv|<1000\rm\,km\,s^{-1}$ from the quasar, providing a unique laboratory to study the link between overdense regions and galaxy properties at high redshift. Even in these rare overdense regions, galaxies are forming stars at a rate consistent with the main sequence at $z\approx3$, demonstrating that their SFR is regulated by local properties correlated with their stellar mass rather than by their environment. However, the high-mass-end of the stellar mass function is significantly elevated with respect to that of galaxies in the field at $\log(M_\star/{M_\odot})\gtrsim10.5$, suggesting that massive galaxies in overdense regions build-up their stellar mass earlier or more efficiently than in average regions of the universe. Finally, the overdensity of color-selected Lyman break galaxies observed on larger scales, across $\approx24\times24\rm\,cMpc^2$, is found to be aligned toward the structure traced by the spectroscopically-confirmed galaxies identified with MUSE in the inner $4\times4\rm\,cMpc^2$, suggesting that this highly overdense region could further extend up to a few tens of comoving Mpc.

description: We construct a 2-categorical extension of the relative entropy functor of Baez and Fritz, and show that our construction is functorial with respect to vertical morphisms. Moreover, we show such a `2-relative entropy' satisfies natural 2-categorial analogues of convex linearity, vanishing under optimal hypotheses, and lower semicontinuity. While relative entropy is a relative measure of information between probability distributions, we view our construction as a relative measure of information between channels.

description: Durante o trabalho de campo realizado para a minha tese de doutoramento na ilha caribenha de San Andrés, tive a ocasião de participar ativamente na realização de vídeos musicais com uma casa de produção local. Mesmo sem ser uma experiência central na construção dos dados etnográficos finalmente utilizados na tese (que se centra no papel das tradições musicais locais nos processos de etnização), a experiência acabou por mudar radicalmente a minha relação com os sujeitos implicados no processo de pesquisa. Foi graças a ela que consegui instaurar uma relação de reciprocidade suficientemente simétrica para superar as barreiras usuais entre investigador e investigados. Nesta comunicação, depois de uma breve narração pessoal da minha colaboração com a Cotton Tree Media e das suas implicações para o trabalho etnográfico, vou refletir sobre diferentes matizes do conceito de colaboração/participação aplicado à pesquisa etnográfica. Em particular, vou começar discutindo aspectos da tradição estadounidense de "collaborative ethnography"; de seguida apresento algumas acepções "politicamente comprometidas" do termo (pesquisaação participativa com movimentos sociais) e vou finalizar traçando as diferenças com a minha experiência de colaboração/participação e esboçando alguns prós e contras.

description: Nonlinear terahertz (THz) spectroscopy relies on the interaction of matter with few-cycle THz pulses of electric field amplitudes up to megavolts/centimeter (MV/cm). In condensed-phase molecular systems, both resonant interactions with elementary excitations at low frequency such as intra- and intermolecular vibrations and nonresonant field-driven processes are relevant. Two-dimensional THz (2D-THz) spectroscopy is a key method for following nonequilibrium processes and dynamics of excitations to decipher the underlying interactions and molecular couplings. This article addresses the state of the art in 2D-THz spectroscopy by discussing the main concepts and illustrating them with recent results. The latter include the response of vibrational excitations in molecular crystals up to the nonperturbative regime of light-matter interaction and field-driven ionization processes and electron transport in liquid water.

description: The Diffuse Interstellar Bands (DIBs) are absorption features seen in the spectra of astronomical objects, that arise in the interstellar medium. Today more than 500 DIBs have been observed mostly in the optical and near-infrared wavelengths. The origin of the DIBs are unclear; only ionized buckminsterfullerene C$_{60}^+$ has been identified as a viable candidate for two strong and three weaker DIBs. In this study, we investigate the correlations between the strengths of the two strongest C$_{60}^+$ DIBs as well as their environmental behaviour. Therefore, we analysed measurements of the strengths of the two C$_{60}^+$ DIBs at 9577 and 9633 $Å$ for 26 lines of sight. We used two different methods, including Monte Carlo simulations, to study their correlations and the influence of measurement errors on the correlation coefficients. Furthermore, we examined how the strength of the C$_{60}^+$ DIBs changes as a result of different environmental conditions, as measured by the concentration of H/H$_2$ and the strength of the ambient UV radiation. In contrast to results recently reported by Galazutdinov et al. (2021), we find a high correlation between the strengths of the C$_{60}^+$ DIBs. We also discovered that the behaviour of the correlated C$_{60}^+$ bands is quite distinct from other DIBs at 5780, 5797 and 6203 $Å$ in different environments.

title: An Investigation of Salinity Fluctuations In Soils of a Northern Utah Marshland
Creators: name: Newman, Gary Roy
Publisher: name: Utah State University
Year: 1979

description: Ogden Bay Waterfowl Management Area is one of many marshlands bordering the Great Salt Lake that are extremely important as breeding habitats for North American waterfowl. Salinity, both of surface and interstitial waters, is an important factor in maintaining a suitable habitat within the marsh. For this reason, a study was undertaken to determine the factors affecting the salinity of surface and interstitial waters. A small (approx. 100 acre) subunit was studied extensively to determine; 1) variations in surface water salinity with flowrate and water level; and 2) variation in interstitial water salinity with depth and location within the subunit. Field data indicated a substantial increase in salinity (as measured by electrical conductance) with depth in the interstitial waters. Wide variation in interstitial water conductivities was also observed within the study unit. Of major significance were large increases in interstitial water salinities in areas where the soil had dried, due to a low water level, and again re-wetted. This was in contrast to relatively constant soil water salinily observed in areas that were perenially flooded In addition to the field study, a laboratory study, using three 20 cm diameter undisturbed soil cores, was performed to determine the factors affecting the movement of salts through the marsh soils. The surface and bottom of the cores were fed with fresh water and brine, respectively, for a period of three months, while interstitial water samples were taken to monitor changes in soil water conductivities with depth of soil. A computer model was developed to simulate the experiment, as well as to help interpret the experimental results. The comparison between the observed data and data predicted by the model, as well as the results of the field data,' indicated that the major mechanisms affecting fluctuations in soil water salinity in the Ogden Bay marsh system is the movement of water through the soil.

description: The purpose of this research was to develop and test a group of predictors that could be used by fundraisers to determine potential corporate support for environmental and recreational programs. Local surveys were conducted to determine environmental and recreational needs for Cache Valley and twenty interviews were held with local corporate managers. The information gathered in these interviews and the literature review provided a list of approximately 20 variables which were narrowed down to 10 to predict both the potential for giving and the level of giving.
A proposal for a youth training project was developed and local Forest Service personnel agreed to administer and supervise the program. The proposal was sent to the twenty corporations previously interviewed. Before asking them for a commitment, each corporation was rated on their potential for giving and level of giving. Results were analyzed using the Chi Square and Pearson coefficient and validated the hypothesis.

description: We present long-term numerical three-dimensional simulations of a relativistic outflow propagating through a galactic ambient medium and environment, up to distances $\sim 100$~kpc. Our aim is to study the role of dense media in the global dynamics of the radio source. We use a relativistic gas equation of state, and a basic description of thermal cooling terms. In previous work, we showed that a linear perturbation could enhance the jet propagation during the early phases of evolution, by introducing obliquity to the jet reverse shock. Here, we show that this effect is reduced in denser media. We find that the dentist-drill effect acts earlier, due to slower jet propagation and an increased growth of the helical instability. The global morphology of the jet is less elongated, with more prominent lobes. The fundamental physical parameters of the jet generated structure derived from our simulations fall within the estimated values derived for FRII jets in the 3C sample. In agreement with previous axisymmetric and three dimensional simulations in lower density media, we conclude that shock heating of the interstellar and intergalactic media is very efficient in the case of powerful, relativistic jets.

A viola e o violão na canção de câmara brasileira: representações musicais
Creators: name: Araújo Garcia, Cláudia
Publisher: name: Post-ip: Revista do Fórum Internacional de Estudos em Música e Dança
Year: 2019

description: Intrinsecamente ligados à canção, a viola e o violão participaram de maneira decisiva no surgimento e configuração dos principais gêneros vocais brasileiros. Trazidos pelos portugueses, esses instrumentos conquistaram enorme popularidade e foram, paulatinamente, se estabelecendo: o violão, na área urbana, tornando­se elemento de mediação e difusão cultural, e a viola, no interior, passando a acompanhar outro tipo de canção, a moda de viola. Perpassando sua vertente popular, precisamos verificar como esses instrumentos se fizeram presentes na canção de câmara brasileira através da representação ou tradução de suas imagens e sonoridades no acompanhamento pianístico. Primeiramente, investigaremos que recursos musicais e idiomáticos são utilizados pelo piano para construir as canções nacionalistas que têm a viola e o violão como título ou tema. Em seguida, estabeleceremos as associações simbólicas a que esses elementos musicais nos remetem, como ambientes, práticas e contextos. Por fim, verificaremos a hipótese de que o violão – combatido e estigmatizado por sua relação com a vadiagem e boemia – seria aceito na esfera erudita através da tradução de sua imagem e sonoridade pelo piano. Ou seja, deslocado de seu espaço original, mas mantendo sua identificação com a cultura brasileira, o violão teria sua entrada permitida através do tratamento artístico e culto que o piano poderia lhe conferir. Para verificar essa representação musical e simbólica, recorremos à análise da obra de importantes compositores nacionalistas como Heitor Villa­Lobos, Oscar Lorenzo Fernandez e Mozart Camargo Guarnieri. De maneira geral, foi possível observar por meio desse estudo que alguns procedimentos, como cromatismos, staccatos, baixos melódicos e contrapontísticos, são comuns tanto à viola quanto ao violão. Porém, a forma de tratá­los modifica seu sentido. Assim, enquanto a viola se traduz através de recursos musicais relacionados ao meio rural, como o uso de terças paralelas e glissandos, o violão se revela caracterizado por sua tradição como instrumento urbano, acompanhador da modinha, onde os elementos do choro e da seresta determinariam não só sua linguagem e espaço como também a formação de um repertório de canção de câmara brasileira originalmente escrito para voz e violão.

description: We present near-infrared spectra of ten luminous, intermediate redshift quasars observed with SofI at the NTT of ESO/La Silla. With these rest-frame optical spectra we probe the Hb -[OIII] emission line region. Using the standard scaling relation involving the width of the Hb line and the continuum luminosity, we measure black hole masses in the range of ~2x10^9 to 10^10 Msol. We also used SDSS spectra to probe MgII2798 and CIV1549 emission lines and used these for black hole mass measurements as well. The massive black holes we observe could not have grown by simple radiatively efficient accretion at the observed accretion rate starting from seeds of up to thousand solar masses. About 10% of the observed black hole mass must have been accumulated by earlier merger events and radiatively inefficient accretion. Radiatively efficient accretion would further grow these BHs to masses of several 10^9 Msol in 2 to 3 e-folding times i.e. in several 10^8yrs. The Hb-based Eddington luminosity ratios are in the range of ~0.2 to ~0.7, with an average of (Lbol/Ledd) = 0.39+-0.05. The Lbol/Ledd ratio distribution follows a log-normal distribution which is consistent with prior studies of quasars with comparable luminosity. The Lbol/Ledd ratio distribution of less luminous quasars tend to be shifted to lower Eddington ratios. We also find that the gas metallicity of the broad-line region is ~3Z/Zsol, using NIII]/OIII] and NV/CIV emission line ratios. We find no correlation of the gas metallicity with the optical FeII emission line strength.

Local and regional earthquakes recorded by the Tasmania Seismic Net
Creators: name: Ripper, ID
Publisher: name: University Of Tasmania
Year: 2023

description: Seismic research has been conducted in Tasmania since 1957, when the Fort Nelson station began operation in Hobart. Three additional stations, Tarraleah, Moorlands and Savannah, were installed in 1960 for the investigation of local seismicity. Fifty-eight earthquakes occurred in Tasmania in the three year period from September, 1960 to December, 1963. The main activity- was in the north west of Tasmania, and south of Macquarie Harbour, where the surface rock is mainly Precambrian and Cambrian sediments and metamorphics. Seismic evidence suggests that the crust in central Tasmania is significantly thicker than the conventional ,3 5 kilometers continental crust. High heat flow adds support to this view, al though the Bouguer gravity anomaly is consistent with the 35 km value. There is a regional distribution of earthquakes which give rise to T:-phase recordings in Tasmania. This results from the effect of bathymetry on the oceanic Sofar channel. There is poor excitation of the T-phase where the continental margin slopes gently from 1000 to 4000 metres near the earthquake, and attenuation of the T- phase where the water depth is less than 3000 - 4 000 metr.es along the wave path. However, in some cases, considerable horizontal curvature around the South Tasmania Ridge occurred. The average crustal thicknesses of the Tasman Sea and the South Tasmania Ridge were found to be approximately 12 k~ and 10 km respectively from Love wave dispersion.

description: In this work we use Floquet-Bloch theory to study the influence of circularly and linearly polarized light on two-dimensional band structures with semi-Dirac band touching points, taking the anisotropic nearest neighbor hopping model on the honeycomb lattice as an example. We find circularly polarized light opens a gap and induces a band inversion to create a finite Chern number in the two-band model. By contrast, linearly polarized light can either open up a gap (polarized in the quadratically dispersing direction) or split the semi-Dirac band touching point into two Dirac points (polarized in the linearly dispersing direction) by an amount that depends on the amplitude of the light. Motivated by recent pump-probe experiments, we investigated the non-equilibrium spectral properties and momentum-dependent spin-texture of our model in the Floquet state following a quench in absence of phonons, and in the presence of phonon dissipation that leads to a steady-state independent of the pump protocol. Finally, we make connections to optical measurements by computing the frequency dependence of the longitudinal and transverse optical conductivity for this two-band model. We analyze the various contributions from inter-band transitions and different Floquet modes. Our results suggest strategies for optically controlling band structures and experimentally measuring topological Floquet systems.

description: Gelation of colloidal nanocrystals (NCs) emerged as a strategy to preserve inherent nanoscale properties in multiscale architectures. Yet available gelation methods still struggle to reliably control nanoscale optical phenomena such as photoluminescence and localized surface plasmon resonance (LSPR) across NC systems due to processing variability. Here, we report on an alternative gelation method based on physical inter-NC interactions: short-range depletion-attractions balanced by long-range electrostatic repulsions. The latter are established by removing the native organic ligands that passivate tin-doped indium oxide (ITO) NCs while the former are introduced by mixing with small polyethylene glycol (PEG) chains. As we incorporate increasing concentrations of PEG, we observe a reentrant phase behavior featuring two favorable gelation windows; the first arises from bridging effects while the second is attributed to depletion-attractions according to phase behavior predicted by our unified theoretical model. The NCs remain discrete within the gel network, based on X-ray scattering and high-resolution transmission electron microscopy. The infrared optical response of the gel is reflective of both the NC building blocks and the network architecture, being characteristic of ITO NC LSPR with coupling interactions between neighboring NCs.
Just resilience in Australian climate adaptation laws

description: Climate adaptation presents a major challenge for Australian law. Australian law has typically struggled to adjust to change, and is already pressured by increasingly frequent and intense climate impacts. New approaches will be needed. Adaptation laws will need to support nimble and responsive adjustments to change. They must also enable transformative change where existing approaches are wholly inadequate given the nature and scale of climate impacts. Yet adaptation laws must also help to facilitate fair and equitable allocations of the costs and benefits of climate adaptation. This latter role is often overlooked in analyses of climate adaptation and law. This thesis argues that law will play a crucial role in promoting both resilience and justice in climate adaptation. Drawing on the extensive scholarly literature on resilience thinking and environmental justice, the thesis develops a conceptual framework of 'just resilience' and applies it to Australian law. The conceptual framework emphasises four interrelated principles for simultaneously enhancing resilience and justice in climate adaptation law. To enhance just resilience, climate adaptation laws must (1) address change; (2) account for the distributive effects of climate change and adaptation; (3) promote participation in adaptation processes; and (4) cross sectors and scales. The implementation of the principles will be context-dependent. The thesis therefore applies the principles of just resilience to three case studies of Australia's current climate adaptation laws: (a) fire in the Tasmanian Wilderness World Heritage Area; (b) water levels in Lake Macquarie, New South Wales; and (c) heatwaves in urban Melbourne. Through a combination of desktop legal analysis and semi-structured interviews with expert practitioners, the case studies explore how existing laws shape resilience and justice in addressing climate impacts in practice. Cross-case comparisons help to emphasise the strengths and limitations of Australia's existing climate adaptation laws. This empirical analysis illustrates how the principles might be pursued in particular contexts, and points to the importance of leadership and information sharing in implementing the four principles of just resilience in practice. The thesis draws together these theoretical and empirical inquiries to examine potential pathways for development and reform of Australia's adaptation laws to meet the demands of a climate impacted future. There is untapped potential for incremental development of existing laws, and the thesis highlights opportunities to implement the just resilience principles through targeted reforms of existing laws. However, the thesis also points to pathways for implementing transformative change where existing legal approaches are inadequate.

description: Nesta comunicação pretendo apontar alguns pontos da pesquisa de doutorado que realizo na UNIRIO (iniciada em 2013), cujo tema é o ensino de canto popular no Brasil. A pesquisa que já realizei até esta fase do trabalho, indica que a oferta de ensino de canto popular tem aumentado no país e que existe a necessidade de criar e desenvolver didáticas que apoiem essa nova demanda. Essa pesquisa pretende localizar uma disputa pelo mercado de trabalho do profissional da voz cantada e sugere que, através da teoria dos campos de Pierre Bourdieu (2003) poderíamos vir a ter um novo entendimento sobre essa realidade. Sugerimos que exista um “campo de ensino de canto no Brasil” e que, além dele, um “subcampo de ensino de canto popular” vem se configurando nos últimos 40 anos. Nesse artigo também vou apresentar um dos questionários que serão enviados a professores de canto popular, para que, através dele, possamos tentar conhecer melhor a realidade de seu trabalho. O objetivo dessa pesquisa consiste em conhecer em profundidade o ensino de canto popular hoje, suas principais tendências e problemas.

description: RU Peg is a dwarf nova (DN) of the U Gem type. Our analysis of its long-term optical activity uses the data from the AAVSO database. It concentrates on investigating the properties of the individual outbursts and the time evolution of the ensemble of these events. No significant irradiation of the disc by the white dwarf was detected. In the interpretation, a variable steepness of the rising branches of the individual outbursts shows that the start of outbursts of RU Peg can occur at various distances from the disc centre without remarkable changes of the outburst recurrence time $T_{\rm C}$. The disc overflow of the inflowing mass stream, varying with time, could contribute to the changes in the starting position of the heating front, hence the variations of the outburst types. A typical length of $T_{\rm C}$ was 90 days. The segments of the relatively stable length of $T_{\rm C}$ were accompanied by the primarily little variable and small values of the fluence (the energy radiated in the optical band in the individual outbursts). Jumps of $T_{\rm C}$, accompanied by the big scatter of the fluences, sometimes replaced them. In the interpretation, a combination of variations of $T_{\rm C}$ with the unstable properties of the outbursts, including an unstable mass transfer rate between the components, shows the influence of several mechanisms on the state of the disc in various time segments.

description: We report on an estimate of the bar pattern speed Omega_p for the low surface brightness spiral galaxy UGC 628. We applied the Tremaine-Weinberg method to high resolution Halpha velocity and integrated emission maps of this dark matter dominated galaxy. Observations were made at the CFHT using the optical Fabry-Perot interferometer, FaNTOmM. The Tremaine-Weinberg method estimates a bar pattern speed of (11.3 +/- 2.0) km/s/kpc for UGC 628, which is among the lowest values found for a spiral galaxy. The corotation radius Rc of the bar and the gaseous disc is Rc = 9.8 (+2.9/-2.0) kpc, implying a ratio R = Rc/Ab of 2.0 (+0.5/-0.3), where Ab is the bar radius. The ratio is well beyond the usual range of values, 1.0< R <1.4, found for fast bars of high surface brightness barred galaxies. It implies that the bar in UGC 628 is slow. As shown through the use of numerical simulations, fast bars survive when the inner mass distribution of galaxies is dominated by the baryons over the dark matter. Our result suggests that the presence of slow bars in galaxies is likely related to the dominance of dark matter over the mass distribution.

description: Thirty diffusion experiments were performed on crystalline samples of Fe-Mg olivine. Interdiffusion coefficients of Fe and Mg have been determined between 900 and 1100°C and from 1 atm. to 35 Kilo-bars using diffusion couples of fayalite from Rockport, Mass. and Fo₉₁Fag olivine from St. John Island, Red Sea, Egypt. The diffusion of cations is strongly dependent on olivine composition and crystallographic orientation. The diffusion coefficient varies with temperature and pressure according to an empirical Arrhenius relationship, with an activation enthalpy for diffusion of ΔH* = 49.83 + 9.05 (N₂) Kilocalories/mole where N₂ = Cation mole fraction Mg An average value of 5.50 cm³/mole was calculated for the activation volume of diffusion. Diffusion couples of Red Sea olivine-MgO powder and couples of Fog₉₃Fa₇ olivine-synthetic forsterite (FO₁₀₀) were used to determine the interdiffusion coefficient of Fe and Mg in olivine between 1200 and 1400° C. The interdiffusion coefficient increases with increasing Fe content and with temperature. Diffusion is faster parallel to the c, [001], axis than paralleltto either a, [100], or b, [010]. At 7 cation mole percent Fe in the olivine, the activation enthalpy [001] is 65.6 - 3.6 kcal/mole. Calculations of ionic electrical conductivity in olivine usingCresultsiofiathis investigation agree with observed conductivity measurements. The results indicate that at depths greater than 100 Km. in the mantle ionic conduction is the dominant mechanism of electrical conduction. Estimates of temperature versus depth are made using the derived donductivities in con-junction with conductivity-depth profiles calculated from published electromagnetic depth sounding results. Experimental and theoretical results of steady state creep studies suggest that the large scale deformation of the upper mantle is ultimately controlled by diffusion in the olivine lattice. Results of this investigation indicate that cationic diffusion is not the rate controlling process in the deformation of silicates. The investigation also indicates that the theories relating cation diffusion to melting in metals may be extended to include silicates.
