Published: November 2017

<p>Compreende-se a centralidade intraurbana como especializações funcionais de algumas frações espaciais da cidade que se singularizam a partir da concentração e geração de fluxos permanentes de pessoas e mercadorias. Nessa direção, a centralidade dos serviços de saúde de Teresina tem seu marco inicial com a instalação do Hospital Getúlio Vargas (1941) no centro histórico da cidade. Desde então, diversos hospitais, clínicas, laboratórios e atividades correlatas aí se instalaram, o que lhes configura como o espaço de maior concentração destes na cidade. Mas, a partir dos anos 2000 inicia-se um processo de descentralização dos serviços de saúde para outros espaços citadinos, notadamente para os bairros mais centrais da zona Leste. Nesse sentido, objetiva-se analisar a produção espacial da centralidade dos serviços de saúde na zona Leste de Teresina, pautado em depoimentos de profissionais e empreendedores dos bairros Fátima, Jóquei e São Cristóvão que lidam com os referidos serviços. Argumenta-se que a constituição dessa nova centralidade dos serviços de saúde de Teresina baseia-se na busca do segmento de renda alta da cidade, o qual exige serviços exclusivos e próximos aos seus locais de moradia ou de mais fácil acessibilidade quando comparados aos encontrados no centro principal.</p><p><strong>Palavras-chaves</strong>: Centralidade.

Since then, several hospitals, laboratories and related activities have been installed, which is configured as their greatest concentration space of this city. But, from 2000, a process of decentralization of health services has begun to other city places, mainly to the more central districts of the East region. This way, it is aimed to analyze the space production of the centrality of the health services in the least region of Teresina, based on the testimony of the professionals and entrepreneurs of the districts of Fátima, Jóquei and São Cristóvão that deal with such services. It argues that the constitution of this new centrality of health services in Teresina is based on the search for the high income population of the city, which demands exclusive services and near their living places or of easier accessibility when compared to the ones found in the main downtown. </p><p><strong>Keywords</strong>: Centrality.

The Geodetic Signature of the Earthquake Cycle at Subduction Zones: Model Constraints on the Deep Processes

Published: November 2017

AbstractRecent megathrust events in Tohoku (Japan), Maule (Chile), and Sumatra (Indonesia) were well recorded. Much has been learned about the dominant physical processes in megathrust zones: (partial) locking of the plate interface, detailed coseismic slip, relocking, afterslip, viscoelastic mantle relaxation, and interseismic loading. These and older observations show complex spatial and temporal patterns in crustal deformation and displacement, and significant differences among different margins. A key question is whether these differences reflect variations in the underlying processes, like differences in locking, or the margin geometry, or whether they are a consequence of the stage in the earthquake cycle of the margin. Quantitative models can connect these plate boundary processes to surficial and far‐field observations. We use relatively simple, cyclic geodynamic models to isolate the first‐order geodetic signature of the megathrust cycle. Coseismic and subsequent slip on the subduction interface is dynamically (and consistently) driven. A review of global preseismic, coseismic, and postseismic geodetic observations, and of their fit to the model predictions, indicates that similar physical processes are active at different margins. Most of the observed variability between the individual margins appears to be controlled by their different stages in the earthquake cycle. The modeling results also provide a possible explanation for observations of tensile faulting aftershocks and tensile cracking of the overriding plate, which are puzzling in the context of convergence/compression. From the inversion of our synthetic GNSS velocities we find that geodetic observations may incorrectly suggest weak locking of some margins, for example, the west Aleutian margin.

AbstractThe thermal evolution of distal domains along rifted margins is at present poorly constrained. In this study, we show that a thermal pulse, most likely triggered by lithospheric thinning and asthenospheric rise, is recorded at upper crustal levels and may also influence the diagenetic processes in the overlying sediments, thus representing a critical aspect for the evaluation of hydrocarbon systems. The thermal history of a distal sector of the Alpine Tethys rifted margin preserved in the Ligurian Alps (Case Tuberto‐Calizzano unit) is investigated with thermochronological methods and petrologic observations. The studied unit is composed of a polymetamorphic basement and a sedimentary cover, providing a complete section through the prerift, synrift, and postrift system. Zircon fission track analyses on basement rocks samples suggest that temperatures exceeding ~240 ± 25°C were reached before ~150–160 Ma (Upper Jurassic) at few kilometer depth. Neoformation of green biotite, stable at temperatures of ~350 to 450°C, was synkinematic with this event. The tectonic setting of the studied unit suggests that the heating‐cooling cycle took place during the formation of the distal rifted margin and terminated during Late Jurassic (150–160 Ma). Major crustal and lithospheric thinning likely promoted high geothermal gradients (~60–90°C/km) and triggered the circulation of hot, deep‐seated fluids along brittle faults, causing the observed thermal anomaly. Our results suggest that rifting can generate thermal perturbations at relatively high temperatures (between ~240 and 450°C) at less than 3 km depth in the distal domains during major crustal thinning preceding breakup and onset of seafloor spreading.
What Do They Have in Common? Drivers of Streamflow Spatial Correlation and Prediction of Flow Regimes in Ungauged Locations

Published: November 2017

AbstractThe spatial correlation of daily streamflows represents a statistical index encapsulating the similarity between hydrographs at two arbitrary catchment outlets. In this work, a process‐based analytical framework is utilized to investigate the hydrological drivers of streamflow spatial correlation through an extensive application to 78 pairs of stream gauges belonging to 13 unregulated catchments in the eastern United States. The analysis provides insight on how the observed heterogeneity of the physical processes that control flow dynamics ultimately affect streamflow correlation and spatial patterns of flow regimes. Despite the variability of recession properties across the study catchments, the impact of heterogeneous drainage rates on the streamflow spatial correlation is overwhelmed by the spatial variability of frequency and intensity of effective rainfall events. Overall, model performances are satisfactory, with root mean square errors between modeled and observed streamflow spatial correlation below 10% in most cases. We also propose a method for estimating streamflow correlation in the absence of discharge data, which proves useful to predict streamflow regimes in ungauged areas. The method consists in setting a minimum threshold on the modeled flow correlation to individuate hydrologically similar sites. Catchment outlets that are most correlated (
) are found to be characterized by analogous streamflow distributions across a broad range of flow regimes.
Evaluation of Macroscopic Porosity‐Permeability Relationships in Heterogeneous Mineral Dissolution and Precipitation Scenarios
Authors: Beckingham Lauren E. 
Published: November 2017

AbstractMineral dissolution and precipitation reactions may alter porosity and permeability in porous media. While porosity generally increases with mineral dissolution and decreases with precipitation, corresponding permeability alterations are complex and predictive capabilities remain limited. The evolution of permeability depends on the spatial locations of geochemical reactions, both in individual pores and in the greater pore network and a range of reaction patterns have been observed in prior experimental investigations. Macroscopic relationships are needed in core‐to‐field scale reactive transport simulations that can accurately simulate permeability evolutions resulting from pore‐scale reactions. Currently, empirical porosity‐permeability relationships, such as the Kozeny‐Carman equation, are widely used to predict permeability evolution. However, these relationships only allow for a single permeability value for each porosity value and the validity of these relationships for the various spatial distributions of pore‐scale alterations is unknown. Using pore network model simulations, changes in permeability resulting from a range of dissolution and precipitation patterns (uniform, random, channelized, and size‐dependent) in a sandstone sample are investigated. The validity of macroscopic porosity‐permeability relationships for these reaction scenarios is evaluated by comparing computed permeability values with pore model simulations. Simulation results exhibit a large variation in porosity‐permeability relationships among reaction scenarios. Macroscopic porosity‐permeability relationships work well for uniform reaction scenarios where the extent of reaction is related to the pore size. The porosity and permeability relationships that result from more complex pore‐scale alterations, including pore size‐dependent reactions however, cannot be captured using these empirical relationships.
Structural Basis for Metastability in Amorphous Calcium Barium Carbonate (ACBC)

Published: November 2017

AbstractMetastable amorphous precursors are emerging as valuable intermediates for the synthesis of materials with compositions and structures far from equilibrium. Recently, it was found that amorphous calcium barium carbonate (ACBC) can be converted into highly barium‐substituted “balcite,” a metastable high temperature modification of calcite with exceptional hardness. A systematic analysis ACBC (Ca1‐xBaxCO3·1.2H2O) in the range from x = 0–0.5 is presented. Combining techniques that independently probe the local environment from the perspective of calcium, barium, and carbonate ions, with total X‐ray scattering and a new molecular dynamics/density functional theory simulations approach, provides a holistic picture of ACBC structure as a function of composition. With increasing barium content, ACBC becomes more ordered at short and medium range, and increasingly similar to crystalline balcite, without developing long‐range order. This is not accompanied by a change in the water content and does not carry a significant energy penalty, but is associated with differences in cation coordination resulting from changing carbonate anion orientation. Therefore, the local order imprinted in ACBC may increasingly lower the kinetic barrier to subsequent transformations as it becomes more pronounced. This pathway offers clues to the design of metastable materials by tuning coordination numbers in the amorphous solid state.

AbstractHigh energy density, durability, and flexibility of supercapacitors are required urgently for the next generation of wearable and portable electronic devices. Herein, a novel strategy is introduced to boost the energy density of flexible soild‐state supercapacitors via rational design of hierarchically graphene nanocomposite (GNC) electrode material and employing an ionic liquid gel polymer electrolyte. The hierarchical graphene nanocomposite consisting of graphene and polyaniline‐derived carbon is synthesized as an electrode material via a scalable process. The meso/microporous graphene nanocomposites exhibit a high specific capacitance of 176 F g−1 at 0.5 A g−1 in the ionic liquid 1‐ethyl‐3‐methylimidazolium tetrafluoroborate (EMIBF4) with a wide voltage window of 3.5 V, good rate capability of 80.7% in the range of 0.5–10 A g−1 and excellent stability over 10 000 cycles, which is attributed to the superior conductivity (7246 S m−1), and quite large specific surface area (2416 m2 g−1) as well as hierarchical meso/micropores distribution of the electrode materials. Furthermore, flexible solid‐state supercapacitor devices based on the GNC electrodes and gel polymer electrolyte film are assembled, which offer high specific capacitance of 180 F g−1 at 1 A g−1, large energy density of 75 Wh Kg−1, and remarkable flexible performance under consecutive bending conditions.

Published: November 2017

AbstractTo meet the increasing demands for portable and flexible devices in a rapidly developing society, it is urgently required to develop highly safe and flexible electrochemical energy‐storage systems. Flexible lithium–oxygen batteries with high theoretical specific energy density are promising candidates; however, the conventional half‐open structure design prevents it from working properly under water or fire conditions. Herein, as a proof‐of‐concept experiment, a highly safe flexible lithium–oxygen battery achieved by the synergy of a vital multifunctional structure design and a unique composite separator is proposed and fabricated. The structure can effectively prevent the invasion of water from the environment and combustion, which is further significantly consolidated with the help of a polyimide and poly(vinylidene fluoride‐co‐hexafluoropropylene) composite separator, which holds good water resistance, thermal stability, and ionic conductivity. Unexpectedly, the obtained lithium–oxygen battery exhibits superior flexibility, water resistance, thermal resistance, and cycling stability (up to 218 cycles; at a high current of 1 mA and capacity of 4 mA h). This novel water/fireproof, flexible lithium–oxygen battery is a promising candidate to power underwater flexible electronics.

AbstractA series of zirconium polyphenolate‐decorated‐(metallo)porphyrin metal–organic frameworks (MOFs), ZrPP‐n (n = 1, 2), featuring infinite ZrIV‐oxo chains linked via polyphenolate groups on four peripheries of eclipse‐arranged porphyrin macrocycles, are successfully constructed through a top–down process from simulation to synthesis. These are the unusual examples of Zr‐MOFs (or MOFs in general) based on phenolic porphyrins, instead of commonly known carboxylate‐based types. Representative ZrPP‐1 not only exhibits strong acid resistance (pH = 1, HCl) but also remains intact even when immersed in saturated NaOH solution (≈20 m), an exceptionally large range of pH resistance among MOFs. The metallation at the porphyrin core gives rise to materials with enhanced sorption and catalytic properties. In particular, ZrPP‐1‐Co, with precise and uniform distribution of active centers, exhibits not only high CO2 trapping capability (≈90 cm3 g−1 at 1 atm, 273 K, among the highest in Zr‐MOFs) but also high photocatalytic activity for reduction of CO2 into CO (≈14 mmol g−1 h−1) and high selectivity over CH4 (>96.4%) without any cocatalyst under visible‐light irradiation (λ > 420 nm). Given the strong chemical resistance under extreme alkali conditions, these catalysts can be recycled without appreciable loss of activity. The possible mechanism for photocatalytic reduction of CO2‐to‐CO over ZrPP‐1‐Co is also proposed.

AbstractSolid‐state batteries (SSBs) are promising for safer energy storage, but their active loading and energy density have been limited by large interfacial impedance caused by the poor Li+ transport kinetics between the solid‐state electrolyte and the electrode materials. To address the interfacial issue and achieve higher energy density, herein, a novel solid‐like electrolyte (SLE) based on ionic‐liquid‐impregnated metal–organic framework nanocrystals (Li‐IL@MOF) is reported, which demonstrates excellent electrochemical properties, including a high room‐temperature ionic conductivity of 3.0 × 10‐4 S cm‐1, an improved Li+ transference number of 0.36, and good compatibilities against both Li metal and active electrodes with low interfacial resistances. The Li‐IL@MOF SLE is further integrated into a rechargeable Li|LiFePO4 SSB with an unprecedented active loading of 25 mg cm‐2, and the battery exhibits remarkable performance over a wide temperature range from −20 up to 150 °C. Besides the intrinsically high ionic conductivity of Li‐IL@MOF, the unique interfacial contact between the SLE and the active electrodes owing to an interfacial wettability effect of the nanoconfined Li‐IL guests, which creates an effective 3D Li+ conductive network throughout the whole battery, is considered to be the key factor for the excellent performance of the SSB.
