Published: April 2018

O presente estudo teve como objetivo identificar situações de violência obstétrica durante o trabalho de parto. Trata-se de um estudo de caso interpretativo em que os dados foram coletados por meio de entrevista semiestruturada nos domicílios de quinze puérperas que realizaram o parto em uma maternidade pública do município sede de uma Regional de Saúde localizada no Estado de Goiás. A análise temática interpretativa foi conduzida por meio das etapas de redução, organização dos dados, identificação das unidades de significado, construção dos núcleos temáticos e interpretação dos resultados. Os resultados foram organizados em dois núcleos temáticos: experiência vivenciada durante a fase inicial do trabalho de parto e a experiência vivenciada pela puérpera durante a fase expulsiva do trabalho de parto. Observou-se através dos relatos das participantes do estudo que, durante o trabalho de parto, houve pelo menos uma forma de violência obstétrica em que a assistência foi baseada na realização de intervenções ineficazes e sem o consentimento da parturiente.

Published: April 2018

Aim:
Anxiety disorders usually remain undiagnosed in school students owing to the internalized nature of their symptoms. The present study was conducted with the primary objective of evaluating the prevalence of anxiety symptoms in school students in Mumbai. A secondary objective was to assess the impact of variables (age, gender, presence of sibling, and type of school curriculum or school) on anxiety symptoms.

Materials and Methods:
Study cases (8–15 year olds) were recruited by nonprobability sampling from four English-medium schools. Anxiety was measured using Spence Children's Anxiety Scale (SCAS)-child self-report questionnaire. T-scores (total and subscales) were calculated and cut-off scores of >60 were considered as significant.

Results:
Symptoms of overall anxiety were present in 10.8% (53/493) of the students. Older students (12–15 year olds) had greater odds of having overall anxiety symptoms (crude OR = 4.36, 95% CI 2.27 to 8.39, P < 0.0001). Symptoms of all anxiety disorders were present in the 493 participants, with obsessions/compulsions and fears of physical injury being the most common (in 29.6% and 27.2%, respectively). Older students and boys had greater odds of having obsessions/compulsions (crude OR = 2.32, 95% CI 1.56 to 3.44, P < 0.0001; and crude OR = 1.54, 95% CI 1.04 to 2.27, P = 0.035, respectively]. Students with sibling (s) had greater odds of having fears of physical injury (crude OR = 0.48, 95% CI 0.30 to 0.78, P = 0.003).

Conclusions:
There is an urgent need to screen school students in our city for anxiety disorders.
Yōko Kanno's Cowboy Bebop Soundtrack
Authors: Bridges Rose 
Published: April 2018

Cowboy Bebop is one of the most beloved anime series of all time, and if you ask its fans why, you can expect to hear about its music. Composer Yoko Kanno created an eclectic blend of jazz, rock, lullabies, folk and funk (to list just a few) for Cowboy Bebop’s many moods and environments. Cowboy Bebop’s blend of science fiction, westerns and gangster films promised to be “the work which becomes a new genre itself,” and only Kanno’s score could deliver.
In this volume of 33 1/3 Japan, musicologist Rose Bridges helps listeners make sense of the music of Cowboy Bebop. The book places it within the context of Bebop’s influences and Kanno’s larger body of work. It analyzes how the music tells Spike, Faye, Jet and the rest of the crew’s stories. Cowboy Bebop and its music are like nothing else, and they deserve a guide to match.
33 1/3 Global, a series related to but independent from 33 1/3, takes the format of the original series of short, music-basedbooks and brings the focus to music throughout the world. With initial volumes focusing on Japanese and Brazilian music, the series will also include volumes on the popular music of Australia/Oceania, Europe, Africa, the Middle East, and more.
Forms of Life for Meaghan Morris
Authors: Brown Pam 
Published: April 2018

Meaghan once remarked (I think to the poet and art critic Ken Bolton) that she didn’t like poetry because of all the empty space on the page. A quarter of a century ago in 1992, in Ecstasy and Economics: American Essays for John Forbes, she said she was ‘a desultory reader of poetry’ and that reading poetry might induce a ‘scary cultural estrangement’.1 In the foreword, she extrapolates the ‘awkward’ place of poetry in cultural studies then as being more an American problem than an Australian one but nearly a quarter of a century later I wonder if poetry has made an individuated local spot for itself, or even if it cares to. I mean, ‘should poetry worry?’

The Fractal Nature of Planetary Landforms and Implications to Geologic Mapping
Authors: Robbins Stuart J. 
Published: April 2018

AbstractThe primary product of planetary geologic and geomorphologic mapping is a group of lines and polygons that parameterize planetary surfaces and landforms. Many different research fields use those shapes to conduct their own analyses, and some of those analyses require measurement of the shape's perimeter or line length, sometimes relative to a surface area. There is a general lack of discussion in the relevant literature of the fact that perimeters of many planetary landforms are not easily parameterized by a simple aggregation of lines or even curves, but they instead display complexity across a large range of scale lengths; in fewer words, many planetary landforms are fractals. Because of their fractal nature, instead of morphometric properties converging on a single value, those properties will change based on the scale used to measure them. Therefore, derived properties can change—in some cases, by an order of magnitude or more—just when the measuring length scale is altered. This can result in significantly different interpretations of the features. Conversely, instead of a problem, analysis of the fractal properties of some landforms has led to diagnostic criteria that other remote sensing data cannot easily provide. This paper outlines the basic issue of the fractal nature of planetary landforms, gives case studies where the effects become important, and provides the recommendation that geologic mappers consider characterizing the fractal dimension of their mapped units via a relatively simple, straightforward calculation.
Real‐time hybrid simulation of semi‐active control using shaking table: Proposal and verification of a testing method for mid‐story isolated buildings

Published: April 2018

AbstractThis study proposes a real‐time hybrid simulation method for semi‐active control using a shaking table. The method can be used for simulating a mid‐story isolated building. This simulation system uses a test specimen for the upper structure, a semi‐active damper that is installed in the base isolation layer on the shaking table, and a lumped mass system for a lower structure for the computer simulation. A rotary inertia mass damper that contains magnetorheological fluid is used in the semi‐active control. The semi‐active control cannot avoid a control time lag. This time lag is estimated by assuming a first‐order lag system. The experimental and analytical results considering a control time lag are compared in this study. The validity of the real‐time hybrid simulation is verified.
Chilling Injury in Tropical Crops after Harvest
Authors: Heyes Julian A. 
Published: April 2018

AbstractTropical crops suffer from chilling injury after harvest, which has historically limited their global trade. The primary cause of chilling injury relates to membrane dysfunction leading to altered Ca2+flux and upregulation of cold‐regulated genes via C‐repeat binding factors (CBFs). Secondary damage results from generation of free radicals. Chilling injury leads to a diversity of internal and external symptoms in tropical crops. The most serious are those which occur only internally or take time to display after fresh products leave the chilling environment, as these symptoms are likely to lead to product rejection after purchase. Techniques for the detection of chilling injury by non‐destructive technologies are reviewed. A wide range of techniques has been tested empirically for reducing chilling susceptibility in tropical crops (step‐down cooling, hormetic treatments, intermittent warming, atmosphere modification, chemical treatments, and pre‐harvest manipulation) and is reviewed here. Faster progress may be possible if treatments can be based on knowledge of underlying mechanisms; for example, maximal heat shock protein gene expression may be an indicator of effective heat treatments. Options for introducing greater chilling tolerance through breeding are discussed, using wild relatives or introduced CBFs. Improved technologies are already leading to increased trade in tropical products which is beneficial for tropical economies.
Evolution and Taxonomy of the Grasses (Poaceae): A Model Family for the Study of Species‐Rich Groups
Authors: Hodkinson Trevor R. 
Published: April 2018

AbstractThe grass family Poaceae, with 11 500 species, is economically, ecologically, and evolutionarily one of the most successful species‐rich groups. Because of this, it represents a model family for the study of speciose taxa. Routine DNA sequencing has accelerated progress in the evolutionary study of grasses, leading to more stable taxonomic classifications; prototype DNA barcoding systems; and a better understanding of their biogeography, physiology, and ecology. This article examines the remaining challenges in the evolutionary and taxonomic study of grasses. These include assessing the monophyly of genera, improving species‐level phylogenetics, establishing a comprehensive DNA barcoding system, understanding diversification in geological time and geographical/ecological space, understanding morphological and physiological trait evolution (such as C4photosynthesis, polyploidy, and spikelet morphology), and understanding co‐evolution with other organisms such as herbivores and endophytic/mycorrhizal microbes.

Published: April 2018

AbstractProgramming living cells to organize inorganic nano‐objects (NOs) in a spatiotemporally precise fashion would advance new techniques for creating ordered ensembles of NOs and new bio–abiotic hybrid materials with emerging functionalities. Bacterial cells often grow in cellular communities called biofilms. Here, a strategy is reported for programming dynamic biofilm formation for the synchronized assembly of discrete NOs or hetero‐nanostructures on diverse interfaces in a dynamic, scalable, and hierarchical fashion. By engineering Escherichia coli to sense blue light and respond by producing biofilm curli fibers, biofilm formation is spatially controlled and the patterned NOs' assembly is simultaneously achieved. Diverse and complex fluorescent quantum dot patterns with a minimum patterning resolution of 100 µm are demonstrated. By temporally controlling the sequential addition of NOs into the culture, multilayered heterostructured thin films are fabricated through autonomous layer‐by‐layer assembly. It is demonstrated that biologically dynamic self‐assembly can be used to advance a new repertoire of nanotechnologies and materials with increasing complexity that would be otherwise challenging to produce.

Published: April 2018

AbstractFor many regenerative electrochemical energy‐conversion systems, hybrid electrocatalysts comprising transition metal (TM) oxides and heteroatom‐doped (e.g., nitrogen‐doped) carbonaceous materials are promising bifunctional oxygen reduction reaction/oxygen evolution reaction electrocatalysts, whose enhanced electrocatalytic activities are attributed to the synergistic effect originated from the TM–N–C active sites. However, it is still ambiguous which configuration of nitrogen dopants, either pyridinic or pyrrolic N, when bonded to the TM in oxides, predominately contributes to the synergistic effect. Herein, an innovative strategy based on laser irradiation is described to controllably tune the relative concentrations of pyridinic and pyrrolic nitrogen dopants in the hybrid catalyst, i.e., NiCo2O4 NPs/N‐doped mesoporous graphene. Comparative studies reveal the dominant role of pyridinic‐NCo bonding, instead of pyrrolic‐N bonding, in synergistically promoting reversible oxygen electrocatalysis. Moreover, density functional theory calculations provide deep insights into the corresponding synergistic mechanism. The optimized hybrid, NiCo/NLG‐270, manifests outstanding reversible oxygen electrocatalytic activities, leading to an overpotential different ΔE among the lowest value for highly efficient bifunctional catalysts. In a practical reversible Zn–air battery, NiCo/NLG‐270 exhibits superior charge/discharge performance and long‐term durability compared to the noble metal electrocatalysts.

AbstractEfficient energy storage is a driving factor propelling myriads of mobile electronics, electric vehicles and stationary electric grid storage. Li‐ion batteries have realized these goals in a commercially viable manner with ever increasing penetration to different technology sectors across the globe. While these electronic devices are more evident and appealing to consumers, there has been a growing concern for micro‐to‐mega grid storage systems. Overall, the modern world demands energy in ‘terawatt’ scale. It needs a multipronged approach with alternate technologies complementing the Li‐ion batteries. One such viable approach is to design and implement Na‐ion batteries. With the uniform geographical distribution, abundance and materials economy of Na resources as well as a striking operational similarity to Li‐ion batteries, Na‐ion batteries have commercial potential, particularly for applications unrestricted by volumetric/gravimetric energy density. In pursuit of the development of Na‐ion batteries, suites of oxides, sulfides, fluorides, and polyanionic materials have been reported in addition to several organic complexes. This article gives an overview of recent progress in polyanionic framework compounds, with emphasis on high‐voltage candidates consisting of earth abundant elements. Guided by ternary phase diagrams, recently discovered and potential cathode candidates will be discussed gauging their performance, current status, and future perspectives.

AbstractThe design and fabrication of high‐performance all‐plastic batteries is essentially important to achieve future flexible electronics. A major challenge in this field is the lack of stable and reliable soft organic electrodes with satisfactory performance. Here, a novel all‐plastic‐electrode based Li‐ion battery with a single flexible bi‐functional ladderized heterocyclic poly(quinone), (C6O2S2)n, as both cathode and anode is demonstrated. Benefiting from its unique ladder‐like quinone and dithioether structure, the as‐prepared polymer cathode shows a high energy density of 624 Wh kg−1 (vs lithium anode) and a stable battery life of 1000 cycles. Moreover, the as‐fabricated symmetric full‐battery delivers a large capacity of 249 mAh g−1 (at 20 mA g−1), a good capacity retention of 119 mAh g−1 after 250 cycles (at 1.0 A g−1) and a noteworthy energy density up to 276 Wh kg−1. The superior performance of poly(2,3‐dithiino‐1,4‐benzoquinone)‐based electrode rivals most of the state‐of‐the‐art demonstrations on organic‐based metal‐ion shuttling batteries. The study provides an effective strategy to develop stable bi‐functional electrode materials toward the next‐generation of high performance all‐plastic batteries.

Published: April 2018

AbstractAs an alternative approach for N2 fixation under milder conditions, electrocatalytic nitrogen reduction reaction (NRR) represents a very attractive strategy for sustainable development and N2 cycle to store and utilize energy from renewable sources. However, the research on NRR electrocatalysts still mainly focuses on noble metals, while, high costs and limited resources greatly restrict their large‐scale applications. Herein, as a proof‐of‐concept experiment, taking PdCu amorphous nanocluster anchored on reduced graphene oxide (rGO) as NRR catalysts, the optimum Pd0.2Cu0.8/rGO composite presents a synergistic effect and shows superior electrocatalytic performance toward NRR under ambient conditions (yield: 2.80 µg h−1 mgcat.−1 at −0.2 V vs reversible hydrogen electrode), which is much higher than that of monometallic, especially noble metal, counterparts. The superior catalytic performance of alloy catalysts with low noble metal loading would strongly spur interest toward more researches on NRR catalysts in the future.

AbstractDie Herstellung Gerüst‐basierter, Gitter‐konstruierter 3D‐DNA‐Origami‐Strukturen ist eine aufstrebende, leistungsfähige und vielseitige Technik für die rationale Entwicklung nahezu beliebig strukturierter und monodisperser DNA‐basierter 3D‐Nanoobjekte. Basierend auf der unübertroffenen molekularen Programmierbarkeit der Sequenz‐spezifischen DNA‐Hybridisierung wird hierbei ein langer DNA‐Einzelstrang (Gerüststrang) mit vielen kurzen Einzelstrang‐Oligomeren (Faltungssträngen) zusammengefügt, die den Gerüststrang in einem Schritt zu einem 3D‐Gitter organisieren und so zu nanopartikulären 3D‐Strukturen führen. Die Zahl der Anwendungen von 3D‐DNA‐Origami nimmt stetig zu und steht mit zahlreichen Gebieten der Wissenschaft in Verbindung, z. B. mit anisometrisch strukturierten oder anisotrop funktionalisierten Nanopartikeln, grundlegenden Untersuchungen zur Überstrukturbildung, der Biomedizin und (Bio‐)Physik sowie mit der Sensorik und der Gestaltung optischer Materialien. Dieser Kurzaufsatz diskutiert die Grundlagen und jüngsten Fortschritte, von der Strukturbildung bis zu ausgewählten Anwendungen, und legt dabei den Fokus auf die Förderung eines interdisziplinären Austausches.

Published: April 2018

AbstractThe metallically conductive bis(diimino)nickel framework (NiDI), an emerging class of metal–organic framework (MOF) analogues consisting of two‐dimensional (2D) coordination networks, was found to have an energy storage principle that uses both cation and anion insertion. This principle gives high energy led by a multielectron transfer reaction: Its specific capacity is one of the highest among MOF‐based cathode materials in rechargeable energy storage devices, with stable cycling performance up to 300 cycles. This mechanism was studied by a wide spectrum of electrochemical techniques combined with density‐functional calculations. This work shows that a rationally designed material system of conductive 2D coordination networks can be promising electrode materials for many types of energy devices.

AbstractIn einer Studie zur Aktivierung von As4 zeigen drei [LCo(tol)]‐Komplexe (L=β‐Diiminato) sterische und elektronische Substituenteneinflüsse. Als flankierende Gruppen wurden 2,6‐Diisopropylphenyl (Dipp) und 2,6‐Dimethylphenyl (dmp) verwendet, einer der Liganden verfügt über einen H‐Gerüstsubstituenten (β‐Dialdiminat L0) und zwei weitere über Me‐Substituenten (β‐Diketiminat L3 und L1). In der Reaktion mit As4 wurden zweikernige Produkte [(LCo)2As4] (LM=L0 (1), L1 (2), L3 (3)) isoliert, von denen jedes im Festkörper einen individuell geformten [Co2As4]‐Kern aufweist: oktaedrisch in 1, prismatisch in 2 und Asteran‐ähnlich in 3. Die thermische Behandlung von 3 führt unter Abstraktion eines Arsenatoms zu [(L3Co)2As3] (4). Alle Produkte wurden durch Einkristall‐Röntgenstrukturanalyse, FD‐MS‐Spektrometrie und 1H‐NMR‐Spektroskopie charakterisiert. Eine Erklärung für die unterschiedliche Reaktivität wird vorgeschlagen und DFT‐Rechnungen geben Einblicke in die Beschaffenheit des flexiblen [Co2As4]‐Kerns.
