Objectives: This cross-sectional study evaluated the prevalence of injuries in
the maxillofacial complex of victims of violence attended by a Mobile Emergency
Care Service in a municipality of Northeastern Brazil. Materials and Methods: A total of 2,347 records were evaluated from February 2014
to December 2016, of which 337 (14.3%) corresponded to victims of violence.
Information related to sociodemographic profile, associated factors and
violence was collected. Data were analyzed through descriptive and inferential
statistics, with significance level of 5%. Results:
There was predominance of males (76.3%) and age group of 20-29 years (29.7%). Occurrences
were more frequent at night (61.4%) and at the weekend (40.7%). Alcohol use was
observed in 63.5% of victims and 16.0% reported illicit drug use, with
predominance of crack (92.6%). The most prevalent type of aggression was
physical violence (54.9%). The majority of victims presented a single lesion
(72.7%) with predominance of laceration (80.4%). Cases of head and face
injuries represented, respectively, 33.5% and 35.9% of aggressions. Face
injuries showed association with gender (p = 0.027) and number of injuries (p =
0.042). Conclusions: The main victims
of violence are young men who have used alcohol and illicit drugs. Physical
aggression is the most frequent type of violence, with high occurrence of head
and face injuries. Face injuries showed association with gender and number of
lesions, both being more frequent among women.
Au croisement du genre et de la parentalité : le plafond de mère chez les femmes qualifiées
Authors: Genin Émilie 
Published: February 2019

Cet article aborde la question des inégalités professionnelles vécues par les femmes sous l’angle de l’intersectionalité entre le genre et la parentalité. Depuis cinquante ans, les femmes ont pris leur place sur le marché de l’emploi au Québec. Elles continuent pourtant à subir des discriminations du simple fait d’être des femmes. À ceci, s’ajoute un basculement qui s’opère au moment de l’arrivée des enfants, et qui a été qualifié de « plafond de mère ». Les inégalités professionnelles entre les hommes et les femmes se creusent alors de façon draconnienne et irréversible. En nous basant sur des recherches antérieures, cet article présente certains des mécanismes à travers lesquels se construit le plafonnement professionnel des mères et discute des enjeux qui lui sont associés, notamment ceux relatifs aux intentions de fécondité.
Papa 2.0 au Québec. La légitimité du père dans l’utilisation des semaines parentales
Authors: Harvey Valérie 
Published: February 2019

Si la prise du congé de paternité de trois à cinq semaines est bien rentrée dans les moeurs québécoises, la durée du congé parental est une question délicate dans le couple. Les cinq semaines de congé semblent être devenues une nouvelle norme au Québec, mais le père qui désire partager le congé parental « enlève » des semaines à la mère, toujours perçue comme la prestataire légitime. L’arrivée d’un enfant est un moment de cristallisation qui fixe les responsabilités dans la nouvelle famille. À travers les résultats d’une enquête qualitative réalisée auprès de pères québécois travaillant dans le domaine des technologies de l’information, un congé prolongé pour le père augmente sa confiance quant aux soins du bébé et son implication par la suite. Mais le fait que les pères sont beaucoup moins nombreux à prolonger leur congé parental peut expliquer le partage inégal des tâches ménagères qui persiste.

Published: February 2019

Introduction
During pregnancy, women often change their lifestyle for fear of harmful effects on the child or themselves. In this respect, many women reduce the amount of physical exercise they take, despite its beneficial effects.

Objective
To determine the duration of labor in pregnant women who completed a program of moderate physical exercise in water and subsequently presented eutocic birth.

Methods
A randomized trial was performed with 140 healthy pregnant women, divided into an exercise group (EG) (n = 70) and a control group (CG) (n = 70). The women who composed the study population were recruited at 12 weeks of gestation. The intervention program, termed SWEP (Study of Water Exercise during Pregnancy) began in week 20 of gestation and ended in week 37. Perinatal outcomes were determined by examining the corresponding partographs, recorded by the Maternity Service at the Granada University Hospital Complex.

Results
The intervention phase of the study took place from June through October 2016, with the 120 women finally included in EG and CG (60 in each group). At term, 63% of the women in EG and 56% of those in CG had a eutocic birth. The average total duration of labor was 389.33 ± 216.18 min for the women in EG and 561.30 ± 199.94 min for those in CG, a difference of approximately three hours (p < 0.001).

Conclusions
The women who exercised in water during their pregnancy presented a shorter duration of labor than those who did not. The difference was especially marked with respect to the duration of the first and second stages of labor.

Published: February 2019

AbstractSodium–air (Na–O2) batteries have recently developed as a high theoretical energy density energy storage and conversion system. In particular, Na–O2 batteries with superoxide as the discharge product have a very high round‐trip energy efficiency over lithium–air batteries due to their significantly reduced charging overpotential. However, Na–O2 batteries yet suffer from limited cycling lives because of the formation and incomplete removal of side products during oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) processes, while the mechanism of these processes is still not fully understood. Herein, a detailed investigation on tracking the decomposition pathway of cubic‐shaped micrometer‐sized NaO2 discharge products in Na–O2 batteries with carbon‐based air electrodes is reported. A detailed electrochemical charging mechanism is revealed during the charging process. The evolution of the chemical compositions of the discharge/side products in air electrode during charging is also verified by synchrotron‐based X‐ray absorption spectroscopy experiments. The formation of these intermediate phases other than NaO2 during the charging process results in high overpotentials. These new findings can contribute to a better understanding and the rational design of future Na–O2 batteries.

Published: February 2019

AbstractSodium‐ion batteries (SIBs) are regarded as a complementary technology to lithium‐ion batteries (LIBs) in the effort of searching for alternative energy solutions that are cost‐effective and sustainable. The identification of suitable alternative anode materials is essential to close the gap in energy density between SIBs and LIBs. Solid‐state alloying reactions that work beyond intercalation mechanism are able to provide a significant improvement in specific capacity. This review describes key advances in SIBs with a primary emphasis on alloy anodes. Recent information and results published in the literatures are stressed to provide an overview of their development in SIBs. With the discussion of some of the remaining challenges and possible solutions, the authors hope to sketch out the scope for future studies in this field.

Published: February 2019

AbstractLithium–sulfur (Li–S) batteries are regarded as the promising next‐generation energy storage device due to the high theoretical energy density and low cost. However, the practical application of Li–S batteries is still limited owing to the cycle stability of both the sulfur cathode and lithium anode. In particular, the instability in the bulk and at the surface of the lithium anode during cycling becomes a huge obstacle for the practical application of Li–S battery. Herein, a Li‐rich lithium–magnesium (Li–Mg) alloy is investigated as an anode for Li–S batteries, based on the consideration of improving the stability in the bulk and at the surface of the lithium anode. Our experimental results reveal that the robust passivation layer is formed on the surface of the Li–Mg alloy anode, which is helpful to reduce side reactions, and enable the smooth surface morphology of anode during cycling. Meanwhile, the mixed electron and Li‐ion conducting matrix of the Li‐poor Li–Mg alloy as a porous skeleton structure can also be formed after delithiation, which can guarantee the structural integrity of the anode in the bulk during Li stripping/plating process. Therefore, the Li‐rich Li–Mg alloy is demonstrated to be a very promising anode material for Li–S battery.

AbstractIn this paper, two near‐infrared absorbing molecules are successfully incorporated into nonfullerene‐based small‐molecule organic solar cells (NFSM‐OSCs) to achieve a very high power conversion efficiency (PCE) of 12.08%. This is achieved by tuning the sequentially evolved crystalline morphology through combined solvent additive and solvent vapor annealing, which mainly work on ZnP‐TBO and 6TIC, respectively. It not only helps improve the crystallinity of the ZnP‐TBO and 6TIC blend, but also forms multilength scale morphology to enhance charge mobility and charge extraction. Moreover, it simultaneously reduces the nongeminate recombination by effective charge delocalization. The resultant device performance shows remarkably enhanced fill factor and Jsc. These result in a very respectable PCE, which is the highest among all NFSM‐OSCs and all small‐molecule binary solar cells reported so far.

Published: February 2019

AbstractThe utilization of an inorganic hole‐transport layer (HTL) is one of the most effective methods to improve the stability and reduce the cost of perovskite solar cells (PSCs). However, achieving high‐quality inorganic HTL films, especially HTL films in n‐i‐p structures, via solution processes remains a big challenge. Here, a simple surface modification strategy for low‐cost and stable cuprous oxide (Cu2O) quantum dots is proposed, which utilizes a silane coupling agent. The modified Cu2O can be directly deposited on the perovskite film as the top HTL without decomposing the perovskite to maintain an n‐i‐p structure. The efficiency (18.9%) of PSCs with surface‐modified Cu2O as the HTL is significantly higher than that (11.9%) of PSCs with unmodified Cu2O, which is also the record efficiency for a Cu2O‐based perovskite solar cell in n‐i‐p structure. The enhanced performance of PSCs is attributed to the remarkably enhanced film properties achieved through surface modification. Moreover, because of the dopant‐free technology and hydrophobic surface, the Cu2O‐based PSCs have distinctly better stability than 2,2′,7,7′‐tetrakis[N,N‐di(4‐methoxyphenyl)amino]‐9,9′‐spiro‐bifluorene‐based PSCs.

Published: February 2019

AbstractPhosphorescent near‐infrared (NIR) organic light‐emitting devices (OLEDs) have drawn increasing attention for their promising applications in the fields such as photodynamic therapy and night‐vision readable displays. Here, three simple phosphorescent Pt(II) complexes are synthesized, and their intermolecular interactions are investigated in crystals and neat films by X‐ray single crystal diffraction and grazing‐incidence wide‐angle X‐ray scattering, respectively. The photophysical properties, molecular aggregation (including Pt–Pt interaction), molecular packing orientation, and electron transport ability are all influenced by the strong intermolecular hydrogen bonds. Consequently, the nondoped OLEDs based on tBu‐Pt and F‐Pt show electroluminescent emissions in NIR region with the highest external quantum efficiencies of 13.9% and 16.7%, respectively.

Published: February 2019

AbstractOrganic/inorganic thermoelectric nanocomposites (TENCs) have seized great attention because they integrate the advantages of inorganic (i.e., high electrical conductivity) and organic (i.e., low thermal conductivity and mechanical flexibility) components. Major barriers that obstruct the development of this field are the lack of n‐type TE materials and their relatively low performance, leaving the construction of TE devices difficult to realize. This review article is therefore focused on recent advances on n‐type TENCs that primarily comprise carbon nanotube (CNT) and inorganic nanocrystal (NC)‐based hybrids. CNT‐based n‐type TENCs are fabricated mainly by transforming the p‐type CNT to n‐type with organic dopants or by blending CNTs with n‐type semiconducting polymers. NC‐based n‐type TENCs are typically obtained by blending semiconductor nanocrystals or metallic nanostructures with polymers. Additionally, the fabrication and thermoelectric performance of 2D layered superlattice structures are also reviewed. Finally, an outlook of n‐type TENCs is given with a perspective for their possible future improvements.

Published: February 2019

AbstractThe development of optical imaging techniques has led to significant advancements in single‐nanoparticle tracking and analysis, but these techniques are incapable of label‐free selective nanoparticle recognition. A label‐free plasmonic imaging technology that is able to identify different kinds of nanoparticles in water is now presented. It quantifies the plasmonic interferometric scattering patterns of nanoparticles and establishes relationships among the refractive index, particle size, and pattern both numerically and experimentally. Using this approach, metallic and metallic oxide particles with different radii were distinguished without any calibration. The ability to optically identify and size different kinds of nanoparticles can provide a promising platform for investigating nanoparticles in complex environments to facilitate nanoscience studies, such as single‐nanoparticle catalysis and nanoparticle‐based drug delivery.

Published: February 2019

AbstractElectrochemical reduction of CO2 into energy‐dense chemical feedstock and fuels provides an attractive pathway to sustainable energy storage and artificial carbon cycle. Herein, we report the first work to use atomic Ir electrocatalyst for CO2 reduction. By using α‐Co(OH)2 as the support, the faradaic efficiency of CO could reach 97.6 % with a turnover frequency (TOF) of 38290 h−1 in aqueous electrolyte, which is the highest TOF up to date. The electrochemical active area is 23.4‐times higher than Ir nanoparticles (2 nm), which is highly conductive and favors electron transfer from CO2 to its radical anion (CO2.−). Moreover, the more efficient stabilization of CO2.− intermediate and easy charge transfer makes the atomic Ir electrocatalyst facilitate CO production. Hence, α‐Co(OH)2‐supported atomic Ir electrocatalysts show enhanced CO2 activity and stability.
Synthesis of Ether‐Diols with Low Polarity from Long‐Chained Fatty Alcohols for Use in Block Copolymers
Authors: Huber Veronika Ramona , Riepl Herbert Mathias 
Published: February 2019

AbstractDiol‐terminated polyethers are important intermediates for the manufacturing of block copolymers, but only a few polyethers other than polyethylene glycols are available on a technical scale. Most of them are highly polar. Natural fatty alcohols—converted to similar polyethers—should have a grossly reduced polarity because of a large separation of the oxygen atoms in the C18 chain. A synthesis sequence of polyethers with a longer carbon chain compared to the ethylene glycol‐derived ethers based on commercially available fatty alcohols was designed for a future examination of the hydrophobic properties. Palladium‐catalyzed cleavage of olefinic dialkyl carbonates results in carbon dioxide elimination and subsequent formation of ethers from an allyl‐palladium cation. It could be shown that this process with fatty alcohols like undec‐10‐en‐1‐ol or oleyl alcohol can be run with appreciable yield. Although carbonates were obtained here using expensive chloroformates as starting materials, transesterification of dimethylcarbonates can be used similarly. Ruthenium‐catalyzed acyclic diene metathesis (ADMET) at both chain terminations then was applied to polymerize the ethers. Depending on the alkenyl chain, short oligomers with a degree of polymerization (DP) of about 5–8 seem to be formed according to gel permeation chromatography (GPC).
The Mussel Mytilus galloprovincialis in the Bay of Naples: New Insights on Oogenic Cycle and Its Hormonal Control

Published: February 2019

ABSTRACTThe aim of the present article was to investigate the oogenic cycle of Mytilus galloprovincialis sampled in the Bay of Naples, and to immunolocalize 3β‐hydroxysteroid dehydrogenase (3β‐HSD), 17β‐hydroxysteroid dehydrogenase (17β‐HSD), and P450 aromatase, enzymes involved in the synthesis of two sex hormones: testosterone and 17β‐estradiol. We demonstrate that the oogenic cycle starts in late summer‐early fall and continues in early winter when the first event of spawning occurs; other spawning events take place until June, when the ovary is spent and contains a few empty ovarian follicles and numerous somatic cells, that is, adipogranular cells and vesicular connective tissue cells. During the oogenic cycle, apoptotic events occur at the level of oogonia, previtellogenic oocytes, as well as follicle cells; by contrast, necrosis events probably take place in vitellogenic oocytes, which, once degenerated, transfer their content to healthy oocytes. Finally, the present data demonstrate that 3β‐HSD, 17β‐HSD, and P450 aromatase are present in the ovary both during the reproductive and nonreproductive phases. The possible role of these enzymes during the Mytilus galloprovincialis reproductive cycle is discussed. Anat Rec, 302:1039–1049, 2019. © 2019 Wiley Periodicals, Inc.

ObjectiveNoninfectious aortitis may occur in the context of a recognized systemic disease or as a topographically limited lesion without systemic features, which is called clinically isolated aortitis (CIA). This study was undertaken to better define and stress the limitations of this diagnostic category in a large population of patients in a single center dedicated to aortic diseases and to suggest recommendations for care.MethodsRecords of patients undergoing thoracic aortic surgery (1996–2012) at the Cleveland Clinic were reviewed to identify 196 patients with histopathologically proven aortitis. Clinical diagnoses (giant cell arteritis [GCA], Takayasu arteritis [TAK], CIA, or Other) were determined at the time of surgery. Clinical features, laboratory findings, and imaging results were recorded throughout the follow‐up period. At least 6 months of follow‐up data were available for 73 CIA patients.ResultsThe mean age of the patients at time of surgery was 65.6 years (range 15–88 years); 67% of patients were female, and 90.3% were white. At the time of surgery, 129 patients (65.8%) met criteria for CIA, 42 (21.4%) for GCA, 14 (7.1%) for TAK, and 11 (5.6%) met criteria for other systemic inflammatory diseases. During a mean follow‐up period of 56.2 months, 19% of CIA patients developed new symptoms, 45% developed new radiographic vascular lesions, 40% underwent additional vascular surgery, and 12% died (n = 9). Eleven of 73 patients (15%) initially classified as having CIA developed features of a systemic disease, most often GCA.ConclusionThe majority of patients (66%) with histopathologically proven aortitis have CIA at the time of surgery. CIA patients infrequently report new symptoms over time, but new vascular lesions requiring surgery commonly occur. Serial follow‐up including large vessel imaging is strongly advised for all aortitis patients.

Published: February 2019

AbstractIron nickel cobalt selenides are synthesized through a one‐step hydrothermal method. Quaternary Fe0.37Ni0.17Co0.36Se demonstrates multifunctionality and shows high electrocatalytic activity for quasi‐solid‐state dye‐sensitized solar cells with a power conversion efficiency of 8.42 %, the hydrogen evolution reaction, the oxygen evolution reaction, and water splitting. The electric power output from tandem quasi‐solid‐state dye‐sensitized solar cells under one‐sun illumination is sufficient to split water and exhibits a solar‐to‐hydrogen conversion efficiency of 5.58 % with Fe0.37Ni0.17Co0.36Se as the electrocatalyst in this integrated system. Owing to a remarkable synergistic effect, quaternary Fe0.37Ni0.17Co0.36Se is proven to be superior to ternary nickel cobalt selenide in terms of conductivity, electrocatalytic activity, and photovoltaic performance.
