O objetivo foi sistematizar informações sobre indicadores de qualidade de vida (QV) de professores do Ensino Fundamental e Médio. A busca foi realizada em cinco bases de dados e nas referências dos artigos. Dos 14 estudos resultantes, 57% eram com professores de Educação Básica e 43% de Educação Física. A maioria dos estudos ressaltou insatisfação com a remuneração, condições de trabalho inconvenientes, escassez de tempo, ambiente desfavorável e problemas vocais. Conclui-se que a estrutura física, salários e sistemas organizacionais se destacam na literatura como aspectos negativamente associados à QV de professores. Estas evidências servem para nortear políticas de gestão escolar voltadas à melhoria da QV no trabalho e saúde em profissionais do âmbito escolar.

The Malpelo Plate Hypothesis and implications for nonclosure of the Cocos‐Nazca‐Pacific plate motion circuit
Authors: Zhang Tuo , Gordon Richard G. , Mishra Jay K. , Wang Chengzu 
Published: July 2017

AbstractUsing global multiresolution topography, we estimate new transform‐fault azimuths along the Cocos‐Nazca plate boundary and show that the direction of relative plate motion is 3.3° ± 1.8° (95% confidence limits) clockwise of prior estimates. The new direction of Cocos‐Nazca plate motion is, moreover, 4.9° ± 2.7° (95% confidence limits) clockwise of the azimuth of the Panama transform fault. We infer that the plate east of the Panama transform fault is not the Nazca plate but instead is a microplate that we term the Malpelo plate. With the improved transform‐fault data, the nonclosure of the Nazca‐Cocos‐Pacific plate motion circuit is reduced from 15.0 mm a−1 ± 3.8 mm a−1 to 11.6 mm a−1 ± 3.8 mm a−1 (95% confidence limits). The nonclosure seems too large to be due entirely to horizontal thermal contraction of oceanic lithosphere and suggests that one or more additional plate boundaries remain to be discovered.
High‐speed solar wind stream effects on the topside ionosphere over Arecibo: A case study during solar minimum

Published: July 2017

AbstractThe impact of a high‐speed solar wind stream (HSS) on the topside near‐equatorial ionosphere (Arecibo: 28.17°N, L = 1.3) is investigated for the first time. Although the HSS did not lead to any significant geomagnetic storm activity, the ionosphere over Arecibo became hotter and expanded significantly in altitude as compared to a non‐HSS interval. The O+/H+ transition height hT increased by ~200 km in the daytime and by ~100 km at night. At the hT, the peak ionospheric electron and ion temperatures increased by ~200–500 K during day and by ~50–70 K at night. While the O+ ion concentration exhibited an overall enhancement, deep penetration of the H+ ions below hT are observed during the day. The noontime peak electron density was ~4 times higher during the HSS event compared to the non‐HSS interval. We present three possible mechanisms to explain this topside ionospheric heating.

AbstractDuring the 2013 Southern Oxidant and Aerosol Study, aerosol mass spectrometer measurements of submicron mass and single particles were taken at Look Rock, Tennessee. Their concentrations increased during multiday stagnation events characterized by low wind, little rain, and increased daytime isoprene emissions. Organic mass (OM) sources were apportioned as 42% “vehicle‐related” and 54% biogenic secondary organic aerosol (bSOA), with the latter including “sulfate‐related bSOA” that correlated to sulfate (r = 0.72) and “nitrate‐related bSOA” that correlated to nitrate (r = 0.65). Single‐particle mass spectra showed three composition types that corresponded to the mass‐based factors with spectra cosine similarity of 0.93 and time series correlations of r > 0.4. The vehicle‐related OM with m/z 44 was correlated to black carbon, “sulfate‐related bSOA” was on particles with high sulfate, and “nitrate‐related bSOA” was on all particles. The similarity of the m/z spectra (cosine similarity = 0.97) and the time series correlation (r = 0.80) of the “sulfate‐related bSOA” to the sulfate‐containing single‐particle type provide evidence for particle composition contributing to selective uptake of isoprene oxidation products onto particles that contain sulfate from power plants.
Persistent influence of tropical North Atlantic wintertime sea surface temperature on the subsequent Atlantic hurricane season
Authors: Wang Xidong , Liu Hailong , Foltz Gregory R. 
Published: July 2017

AbstractThis study explores the seasonally lagged impact of wintertime sea surface temperature (SST) in the Atlantic main development region (MDR) on the subsequent Atlantic hurricane season. It is found that wintertime SST anomalies in the MDR can persist into the summer, explaining 42% of the variance in the subsequent hurricane season's SST during 1951–2010. An anomalously warm wintertime in the MDR is usually followed by an anomalously active hurricane season. Analysis shows an important constraint on the seasonal evolution of the MDR SST by the water vapor feedback process, in addition to the well‐known wind‐evaporation‐SST and cloud‐SST feedback mechanisms over the tropical North Atlantic. The water vapor feedback influences the seasonal evolution of MDR SST by modulating seasonal variations of downward longwave radiation. This wintertime thermal control of hurricane activity has significant implications for seasonal predictions and long‐term projections of hurricane activity over the North Atlantic.
Cyclic formation and stabilization of Archean lithosphere by accretionary orogenesis: Constraints from TTG and potassic granitoids, North China Craton

Published: July 2017

AbstractAccretionary orogens are major sites of modern continental growth, yet their role in the development of Archean continental crust remains enigmatic. Diverse granitoid suites from tonalite‐trondhjemite‐granodiorite (TTG) to potassic granitoids appeared during late Archean, representing a period of major continental formation and stabilization. In this study, whole‐rock geochemical and zircon U‐Pb and Lu‐Hf isotopic data are reported for Neoarchean granitoid gneisses from the Northern Liaoning Terrane, northeastern North China Craton (NCC). Older granitoid gneisses (~2592–2537 Ma) define three magmatic zones migrating from southeast to northwest, each showing a common magmatic evolution from high‐pressure TTGs to medium‐/low‐pressure TTGs and potassic granitoids. They have depleted zircon ƐHf(t) of +0.5 to +8.7. Younger ~2529–2503 Ma potassic granitoids and TTGs occur throughout the terrane, which are marked by variable zircon ƐHf(t) of −4.7 to +8.1, and are coeval with regional high‐grade metamorphism. Petrogenetic modeling and changing Sr/Y and (La/Yb)N of the granitoids suggest that the crust experienced episodic thickening and thinning and became progressively evolved through development of potassic granitoids and sedimentary successions. The metavolcanic basement to the granitoids display tholeiitic to calc‐alkaline affinities, together with the top‐to‐the‐northwest thrusting and associated volcanogenic massive sulfide‐type Cu‐Zn deposits, suggesting cyclic crustal formation of Northern Liaoning within an accretionary orogen with a SE‐dipping subduction polarity. Cyclic crustal thickening and thinning is related to tectonic switching from advancing to retreating relations between the downgoing and overriding plate. After ~2530 Ma, this accretionary system accreted to the ancient continental nucleus of NCC (Anshan‐Benxi Terrane), signifying final lithosphere stabilization.

AbstractObjectiveTo examine the diaphragm and chest wall dynamics with cine breathing magnetic resonance imaging (MRI) in ambulatory boys with Duchenne muscular dystrophy (DMD) without respiratory symptoms and controls.MethodsIn 11 DMD boys and 15 controls, cine MRI of maximal breathing was recorded for 10 sec. The lung segmentations were done by an automated pipeline based on a Holistically‐Nested Network model (HNN method). Lung areas, diaphragm, and chest wall motion were measured throughout the breathing cycle.ResultsThe HNN method reliably identified the contours of the lung and the diaphragm in every frame of each dataset (~180 frames) within seconds. The lung areas at maximal inspiration and expiration were reduced in DMD patients relative to controls (P = 0.02 and <0.01, respectively). The change in the lung area between inspiration and expiration correlated with percent predicted forced vital capacity (FVC) in patients (rs = 0.75, P = 0.03) and was not significantly different between groups. The diaphragm position, length, contractility, and motion were not significantly different between groups. Chest wall motion was reduced in patients compared to controls (P < 0.01).InterpretationCine breathing MRI allows independent and reliable assessment of the diaphragm and chest wall dynamics during the breathing cycle in DMD patients and controls. The MRI data indicate that ambulatory DMD patients breathe at lower lung volumes than controls when their FVC is in the normal range. The diaphragm moves normally, whereas chest wall motion is reduced in these boys with DMD.

AbstractFlexible all‐solid‐state supercapacitors (FASS) attract tremendous attention as energy supplies for wearable electronic devices. Graphene nanosheets have gained lots of interest in paper‐like flexible electrodes in FASS due to their unique 2D structure and high mechanical and electrical properties. However, the essential feature of electric double‐layer performance for simple graphene nanosheet‐based FASS restricts the improvement of their capacitive performance and practical applications. This study reports the design of FASS based on ultralarge graphene nanosheets and solvent‐exfoliated tungsten disulfide (WS2) nanoflakes. The free‐standing ultralarge graphene nanosheets/WS2 nanoflakes composite paper electrodes are assembled by vacuum‐assisted filtration. With WS2 nanoflakes intercalated between graphene nanosheets, the ultralarge graphene nanosheets/solvent‐exfoliated WS2 nanoflakes composite paper still exhibits excellent mechanical stability, flexibility, and electrical conductivity. The nacre‐like structures of the papers could efficiently integrate both merits of pseudocapacitive WS2 nanoflakes and conducting graphene, resulting in extraordinary electrochemical performance in FASS. The highest areal specific capacitance of 312.4 mF cm−2 for FASS is achieved with a high capacity retention of ≈88.1% after 5000 charge–discharge cycles. Meantime, the areal power and energy densities of the ultralarge graphene nanosheets/WS2 nanoflakes paper‐based FASS device have a high energy density of 23.1 Wh kg−1 at a power density of 83.2 W kg−1.
Bioinspired Dip Catalysts for Suzuki–Miyaura Cross‐Coupling Reactions: Effect of Scaffold Architecture on the Performance of the Catalyst
Authors: Sharma Vipul , Bahuguna Ashish , Krishnan Venkata 
Published: July 2017

AbstractDip catalysts suitable for catalyzing important chemical reactions are designed based on bioinspiration principles and are fabricated using a facile soft lithography technique. Specifically, in this work, leaves from two different plants, Gladiolus dalenii and Amaryllis belladonna are chosen, due to their contrasting surface topographical features. The surface microstructures of these two leaves are replicated on a polymer in order to prepare scaffolds for the fabrication of dip catalysts. The microstructures of these scaffolds are utilized to direct the self‐assembly of Pd nanoparticles according to the surface topographical features. A thin film of polyvinyl alcohol is used to lock the nanoparticles on the surface and prevent them from leaching. The fabricated bioinspired dip catalysts are thoroughly characterized and are demonstrated to be highly efficient for Suzuki–Miyaura cross‐coupling reactions, examined under different experimental conditions. These bioinspired dip catalysts' performance is evaluated based on the percentage yields of the reaction and is correlated with the corresponding surface topographical features to understand the effect of the scaffold architecture on the performance of the catalysts. The developed strategy can be easily adopted to fabricate many more dip catalysts, with intriguing surface features, suitable for catalyzing several other chemical reactions as well.
A Biocatalytic One‐Pot Approach for the Preparation of Lignin Oligomers Using an Oxidase/Peroxidase Cascade Enzyme System

Published: July 2017

AbstractSynthetic lignin was prepared biocatalytically in a one‐pot, two‐step reaction using an oxidase/peroxidase cascade enzyme system. Using eugenol in combination with eugenol oxidase and a peroxidase, lignin‐like material was produced. The cascade reaction takes advantage of the ability of the oxidase to produce coniferyl alcohol and hydrogen peroxide from eugenol and molecular oxygen. The hydrogen peroxide is used by the peroxidase for the formation of crosslinks that typify lignin. As eugenol oxidase has a broad substrate acceptance profile, also 4‐allylphenol (chavicol) and 4‐allyl‐2,6‐dimethoxyphenol could be used as precursors of the synthetic lignin. As a result, all three naturally occurring monolignols could be prepared and incorporated in the synthetic lignin. The reaction was optimized in order to achieve the highest possible yield of insoluble lignin oligomers and scaled up to 1 gram. Analysis of the water‐insoluble product by gel permeation chromatography revealed the formation of relatively small lignin oligomers (≈1000 dalton). By using two‐dimensional heteronuclear single quantum coherence nuclear magnetic resonance spectroscopy (2D HSQC NMR) analysis it could be demonstrated that the material contained α‐O‐4/β‐O‐4, β‐O‐4, β‐β, β‐5 linkages and dibenzodioxocin units. All these features indicate that the biocatalytically produced material closely resembles natural lignin. While 54% of eugenol was converted into water‐insoluble oligomers, the remaining substrate was converted into water‐soluble dimers and tetramers which are important lignin model compounds. Therefore, the presented method represents a valuable and facile biocatalytic approach for the preparation of lignin‐like material and potentially valuable chemicals.magnified image

AbstractThis paper reports an entirely unexplored concept of simultaneously recognizing two receptors using high‐ and low‐affinity ligands through ligating them in situ on the target cell surface. This de novo approach is inspired by the pretargeting strategy frequently applied in molecular imaging, and has now evolved as the basis of a new paradigm for visualizing target cells with a high imaging contrast. A distinct advantage of using a labeled low‐affinity ligand such as glycan is that the excess labeled ligand can be washed away from the cells, whereas the ligand bound to the cell, even at the milli molar affinity level, can be anchored by a bioorthogonal reaction with a pretargeted high‐affinity ligand on the surface. Consequently, nonspecific background is minimized, leading to improved imaging contrast. Importantly, despite previously unexplored for molecular imaging, a notoriously weak glycan/lectin interaction can now be utilized as a highly selective ligand to the targets.

Published: July 2017

CaseReversible cerebral vasoconstriction syndrome (RCVS) is an increasingly recognized and important cause of thunderclap headache. Delays in diagnosis may cause deterioration of symptoms and concomitant unnecessary investigations. However, the diagnosis of RCVS in the acute stage remains difficult.A 41‐year‐old man was admitted to the emergency department for severe, recurrent occipital headaches. The results of initial computed tomography and magnetic resonance imaging (MRI) of the brain and cerebrospinal fluid analysis were normal. Magnetic resonance angiography (MRA) showed multisegmental luminal stenosis of the basilar artery. Basi‐parallel anatomical scanning (BPAS)‐MRI, illustrating the outer contour of the vertebrobasilar artery, also showed multisegmental stenosis.OutcomeThe patient was speculated as having RCVS and was treated with oral lomerizine hydrochloride. Repeat MRA and BPAS‐MRI 2 months later showed resolution, confirming RCVS.ConclusionCombined with MRA, BPAS‐MRI is an effective and non‐invasive imaging method for diagnosis of RCVS of the basilar artery.

Published: July 2017

ABSTRACTA series of solid polymer electrolytes (SPEs) based on comb‐like nonionic waterborne polyurethane (NWPU) and LiClO4 are fabricated via a solvent free process. The NWPU‐based SPEs have sufficient mechanical strength which is beneficial to their dimensional stability. Differential scanning calorimetry analysis indicates that the phase separation occurs by the addition of the lithium salt. Scanning electron microscopy and X‐ray diffraction analyses illustrate the good compatibility between LiClO4 and NWPU. Fourier transform infrared study reveals the complicated interactions among lithium ions with the amide, carbonyl and ether groups in such SPEs. AC impedance spectroscopy shows the conductivity of the SPEs exhibiting a linear Arrhenius relationship with temperature. The ionic conductivity of the SPE with the mass content of 15% LiClO4 (SPE15) can reach 5.44 × 10−6 S cm−1 at 40 °C and 2.35 ×10−3 S cm−1 at 140 °C. The SPE15 possesses a wide electrochemical stability window of 0–5 V (vs. Li+/Li) and thermal stability at 140 °C. The excellent properties of this new NWPU‐based SPE are a promising solid electrolyte candidate for all‐solid‐state lithium ion batteries. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
