Violencia de Género y embarazo en adolescentes
Authors: ´Pacheco Ángela Bersabé 
Published: August 2019

El objetivo fundamental de este estudio consiste en establecer la relación entre embarazo en adolescentes y la violencia de género, realizando estudios de variables tales como escolaridad, ocupación, estado familiar, nivel socioeconómico y experiencia de violencia. El embarazo precoz resulta ser la suma de una serie de acontecimientos biológicos, sociales, económicos y culturales, cuyo análisis requiere no solo la retórica explicación tradicional; sino además, tomar en cuenta la complejidad y la diversidad de factores vinculados al mismo, en especial la violencia de género. Está investigación de corte cuantitativo, describe a través del estudio de casos de siete adolescentes gestantes entre los 15 y 17 años, residentes en Ciudad Barrios, San Miguel; como la falta de información, la invisibilización cultural de la mujer y su objetivación sexual son elementos indisolubles de está problemática. Los resultados evidencian la presencia de violencia de género en todas las cosas, aun cuando la participación no la reconoce como tal. Inicialmente, estos resultados servirán de base para la ejecución de indagaciones más profundas, además de ser utilizados en el diseño de programas de prevención y acciones de atención a la mujer adolescente embarazada.
“I’ve Been Bad”: Using Light Verse in Teaching Philosophy
Authors: Ackerman Felicia Nimue 
Published: August 2019

Abstract
Conventional wisdom in our society is that a good death involves accepting it as natural rather than striving to stave it off as long as possible. An alternative view is “Death can be good / I’ll show you how / Just have it come / decades from now.” In this essay, I discuss how I use this poem and other light verses of mine in teaching philosophy. These poems offer unusual viewpoints in several additional areas of philosophical and bioethical interest, including growth through adversity, old age, family relations, obesity, envy, inequality, and ambition. Such poems can supplement traditional philosophical writing by presenting these alternative viewpoints in an amusing way that can capture students’ attention and relieve the solemnity that often pervades philosophy courses.
Appearance Emotionalism in Music: Analysis and Criticism
Authors: Ravasio Matteo 
Published: August 2019

Abstract
This paper is composed of two related parts. The first raises questions regarding the characterization of the phenomenology of music listening required by Davies’s theory of musical expressiveness, appearance emotionalism. I will identify two possible readings of the theory, a thick and a thin one, and claim that the former represents the basic characterization of what it is to hear expressive music according to appearance emotionalism. The thick characterization is to be preferred, I will claim, both on the grounds of textual evidence and of overall consistency and explanatory power. The second part of the paper discusses a criticism of appearance emotionalism I advanced in a recently published paper, along with its consequences for aesthetic education. In the remainder of the paper, I address Davies’s twofold reply to my objection. I contend that both replies fail to address at least some of the problems I raised. The first reply fails because of Davies’s own view of emotions, while the seconds fails if one accepts the thick characterization of appearance emotionalism I offer in the first half of the paper.

Nos últimos anos os estudos morfométricos do relevo tem avançado significativamente na obtenção de dados para a análise da paisagem, sendo a automatização através do uso de SIGs um dos principais diferenciais da análise morfométrica, trazendo velocidade de análise e diminuindo a subjetividade do pesquisador. Desta forma, esse trabalho tem como objetivo analisar a rugosidade do relevo do município de Canguçu – RS. Para tanto utilizou-se da ferramenta de estatística de vizinhança Focal Statistics estabelecendo padrões do relevo, divididos em quatro classes. No município houve um predomínio da classe de relevo ondulado presente sob o maciço granítico mais resistente ao intemperismo. A classe de relevo levemente ondulado foi a segunda com maior ocorrência, com quase 20% da área total, associado as áreas de topo de divisores de água. De forma geral a metodologia empregada obteve resultados satisfatórios, permitindo uma análise geral do relevo do município, sendo uma importante contribuição para a análise morfométrica.Palavras–chave: Morfometria, Rugosidade do Relevo, Estatística Espacial, Canguçu – RS.Abstract In the last years, morphometric studies of the relief have advanced significantly in obtaining data for the landscape analysis, being the automation using SIGs one of the main differentials of the morphometric analysis, bringing faster analysis and reducing the subjectivity of the researcher. In this way, this work has as objective to analyse the roughness of the relief of the municipality of Canguçu - RS. In order to this, was used the neighbourhood statistics tool called Focal Statistics, establishing relief patterns, divided into four classes. In the municipality, there was a predominance of the class of undulated relief present under the granite massif more resistant to weathering. The slightly waved relief class was the second with the highest occurrence, with almost 20% of the total area, associated with the top areas of water dividers. In general, the methodology used obtained satisfactory results, allowing a general analysis of the relief of the municipality, being an essential contribution to the morphometric analysis.Keywords: Morphometry, Relief Roughness, Spatial Statistics, Canguçu - RS.
Images de la femme aimée dans le cycle de Marie de Jean-Philippe Toussaint : entre roman et cinéma
Authors: Clamens-Nanni Frédéric 
Published: August 2019

Avant de devenir l’une des figures de proue des Éditions de Minuit depuis les années 1980, Jean-Philippe Toussaint avait jeté son dévolu sur le cinéma, comme il l’explique dans L’urgence et la patience (2012). C’est pourtant vers la littérature qu’il s’est tourné, suivant un conseil de François Truffaut qui recommandait « à tous les jeunes gens qui rêvaient de faire du cinéma, mais qui n’en avaient pas les moyens, d’écrire un livre, de transformer leur scénario en livre » (L’urgence et la patience). Si l’écriture de Toussaint est considérée comme cinématographique par la critique, l’auteur refuse ce qualificatif parce que littérature et cinéma sont des arts distincts qui ne répondent pas aux mêmes intentions ni ne produisent les mêmes effets. Les images cinématographiques s’impriment sur une pellicule à partir de la lumière projetée sur des objets tangibles. Les images littéraires, quant à elles, sont « faite[s] de mots » (L’urgence et la patience). Le roman est le lieu où s’expérimente une nouvelle poétique de l’image qui puise ses sources dans la littérature et le cinéma ou, plus précisément, entre littérature et cinéma. En témoignent les images de la femme aimée dans le cycle de Marie. Point de mire du narrateur, l’héroïne n’est paradoxalement jamais décrite. Dans le spectacle Marie Madeleine Marguerite de Montalte que Toussaint a créé avec The Delano Orchestra à la Comédie de Clermont-Ferrand, l’écrivain a intégré des vidéos dans lesquelles l’héroïne n’est jamais visible, alors qu’il avait tourné une scène de Fuir au Louvre avec l’actrice Dolores Chaplin. Marie demeure mouvante, insaisissable. De telles images en creux ne sauraient être captées par l’objectif d’une caméra ; elles participent d’un art de la suggestion sollicitant un imaginaire syncrétique qui, entre roman et cinéma, convoque d’autres arts comme la peinture ou la photographie. Ainsi, l’écriture de Toussaint est plus visuelle que cinématographique.
Ascenseur pour l’échafaud en images fixes, Louis Malle en roman-photo
Authors: Baetens Jan 
Published: August 2019

Le cinéma et la culture cinématographique ont suscité un grand nombre de genres nouveaux en littérature, dont certains sont plus renommés et surtout plus vivants que d’autres. Cet article analysera un genre très peu connu et aujourd’hui presque totalement oublié : le ciné-roman-photo, croisement du ciné-roman et du roman-photo et dont l’âge d’or se situe dans les années 1955-1965. Après avoir présenté les grandes caractéristiques de ce genre et les défis qu’il pose à la poétique du cinéma raconté, l’article analyse un exemple représentatif, à savoir deux ciné-romans-photos (l’un très court, de huit pages, l’autre de longueur plus habituelle, soit cinquante pages) tirés d’Ascenseur pour l’échafaud de Louis Malle (adapté du roman éponyme de Noël Calef). L’analyse se propose de mettre en lumière aussi bien les analogies que les différences entre ces deux versions, que tout devrait opposer mais qui se ressemblent aussi de manière assez étrange. Plus concrètement, la lecture tente d’interpréter les conséquences d’un aspect singulier de certains ciné-romans-photos, à savoir l’emploi de photos de plateau et non pas de photogrammes. Les effets de ce choix sont évalués à la lumière de l’esthétique de la contrainte, qui définit assez généralement un genre où très peu, à première vue, semble possible ou autorisé à ceux qui adaptent un film en ciné-roman-photo.

The concentrations of five essential metals in six selected (NAN, Cowbell, MY BOY, CERELAC, FRISO GOLD and NUTREND) infant formulae sold in Makurdi metropolis, were determined using Atomic Absorption Spectrophotometer. Data collected were subjected to Analysis of Variance using SPSS 24 statistical software package. Significant differences in means were separated using Duncan Multiple Range Test. There was significant difference in the levels of the trace metals in the different brands of infant formula milk. The results of the toxic trace metals show that Cr has the highest concentration of 6.175 ±0.001 mg/kg (Cowbell), when compared to other toxic trace metals analyzed. Milk based infant formula showed copper concentration ranged from 2.55±0.001– 6.357±0.001mg/kg, which was higher than the provisional tolerable daily intake of copper that is 3 mg/kg. Chromium, Copper, Manganese and lead were detected in the six brands of infant formula milk but they were below the limits set by World Health Organization (WHO). However, the intake levels of Cd in this study from these concentrations were below the WHO limits. These results validate and in some cases counter earlier reports on the composition of infant formula found in our local markets. Therefore, the concentrations of the studied elements were within the safe limits recommended by National Industrial Standard and the Institute of Medicine for foods but higher concentrations of trace metals in some brands of infant formulae above the recommended limit pose a risk of bioaccumulation.

Published: August 2019

AbstractDeveloping high‐performance noble metal–free electrodes for efficient water electrolysis for hydrogen production is of paramount importance for future renewable energy resources. However, a grand challenge is to tailor the factors affecting the catalytic electrodes such as morphology, structure, and composition of nonprecious metals. Alloying catalytic metals can lead to a synergistic effect for superior electrocatalytic properties. However, alloy formation in solution at low synthesis temperatures may result in better catalytic properties as compared to those at high temperatures due to the controlled reaction kinetics of nucleation and growth mechanisms. Herein, an aqueous solution–based preparation technology is developed to produce NiMo alloy nanowire arrays. The NiMo alloy shows significantly improved hydrogen evolution reaction (HER) catalytic activity, featured with extremely low overpotentials of 17 and 98 mV at 10 and 400 mA cm−2, respectively, in an alkaline medium, which are better than most state‐of‐the‐art non‐noble metal–based catalysts and even comparable to platinum‐based electrodes. Analyses indicate that the lattice distortions induced by Mo incorporation, increased interfacial activity by alloy formation, and plenty of MoNi4 active sites at nanowires surface collectively contribute to remarkably enhanced catalytic activity. This study provides a powerful toolbox for highly efficient nonprecious metal–based electrodes for practical HER application.

AbstractDespite the good prognosis of the low‐risk thyroid cancer, there are no truly effective treatments for radioactive iodine‐refractory thyroid cancer. Herein, a novel theranostic nanoplatform, as well as a smart doxorubucin (DOX) delivery system is fabricated. Gelatin‐stabilized polypyrrole nanoparticles are reported for the first time. The combination of gelatin‐stabilized polypyrrole and cyclodextrin‐DOX complexes enabling three‐stimuli‐controlled drug delivery, including the enzyme‐sensitive, pH‐sensitive and photothermal‐sensitive drug release, exhibiting a new way to equip photothermal agents with precisely controlled drug delivery. Anti‐galectin‐3 antibodies are utilized as the targeting molecules of nanoparticles in the first time, which surprisingly increase intracellular DOX uptake by enhanced clathrin‐mediated endocytosis, showing galectin‐3 can be employed as a highly efficient target of drug delivery systems. The nanoparticles achieve excellent photoacoustic imaging effect, enabled chemo‐photothermal combined therapy with pinpointed drug delivery. Compared to free DOX, these multifunctional nanoparticles decrease the heart damage, but greatly increase the tumor/heart ratio of DOX concentration by 12.9‐fold. The tumors are completely eradicated without any recurrence after the in vivo combined therapy. To the best of the authors' knowledge, this is also the first report to apply photoacoustic imaging‐guided chemo‐photothermal therapy for thyroid cancer, showing great potential to solve the dilemma in thyroid cancer therapy.

Authors: Tang Lei , Meng Xianguang , Deng Dehui , Bao Xinhe 
Published: August 2019

AbstractThe unique electronic and structural properties of 2D materials have triggered wide research interest in catalysis. The lattice of 2D materials and the interface between 2D covers and other substrates provide intriguing confinement environments for active sites, which has stimulated a rising area of “confinement catalysis with 2D materials.” Fundamental understanding of confinement catalysis with 2D materials will favor the rational design of high‐performance 2D nanocatalysts. Confinement catalysis with 2D materials has found extensive applications in energy‐related reaction processes, especially in the conversion of small energy‐related molecules such as O2, CH4, CO, CO2, H2O, and CH3OH. Two representative strategies, i.e., 2D lattice‐confined single atoms and 2D cover‐confined metals, have been applied to construct 2D confinement catalytic systems with superior catalytic activity and stability. Herein, the recent advances in the design, applications, and structure–performance analysis of two 2D confinement catalytic systems are summarized. The different routes for tuning the electronic states of 2D confinement catalysts are highlighted and perspectives on confinement catalysis with 2D materials toward energy conversion and utilization in the future are provided.

Published: August 2019

AbstractSmall‐molecule electrolyte (C6‐E‐OTs) hybridized ZnO layer is provided as the electron transporting layer. The device based on the blend of PTB7 and PC71BM as the active layer shows an enhanced power conversion efficiency (PCE) from 7.6% based on ZnO to 8.8% using the C6‐E‐OTs hybridized ZnO layer. The device can be further improved by simultaneously using a C6‐E‐OTs hybridized ZnO layer and a 5 nm thick C6‐E‐OTs as the interlayer. The synergy effect of hybridization and interlayer enhanced the PCE of the device to 8.9%, which is a 17.1% increase in comparison with the device based on ZnO. The presence of C6‐E‐OTs hybridized ZnO and a 5 nm of C6‐E‐OTs as the interlayer in the device with PTB7‐Th as the donor significantly improves the PCE from 8.0% based on ZnO to 9.4%, resulting in a 17.5% enhancement. Main contribution for enhancing the PCE of the device is the improved Jsc, which results from the reduction of energy offset at the cathode interface. Thus, hybridized ZnO layer process can overcome the limitation faced by the thickness tolerance of interlayer.

Published: August 2019

AbstractFabrication of multiscale, multimaterial 3D structures at high resolution is difficult using current technologies. This is especially significant when working with mechanically weak hydrogels. Here, a new hybrid laser printing (HLP) technology is reported to print complex, multiscale, multimaterial, 3D hydrogel structures with microscale resolution. This technique utilizes sequential additive and subtractive modes of fabrication, that are typically considered as mutually exclusive due to differences in their material processing conditions. Further, compared to current laser writing systems that enforce stringent processing depth limits, HLP is shown to fabricate structures at any depth inside the material. As a proof‐of‐principle, a Mayan pyramid with embedded cube frame is printed using synthetic polyethylene glycol diacrylate (PEGDA) hydrogel. Printing of ready‐to‐use open‐well chips with embedded microchannels is also demonstrated using PEGDA and gelatin methacrylate (GelMA) hydrogels for potential applications in biomedical sciences. Next, HLP is used in additive–additive modes to print multiscale 3D structures spanning in size from centimeter to micrometers within minutes, which is followed by printing of 3D, multimaterial, multiscale structures using this technology. Overall, this work demonstrates that HLP's fabrication versatility can potentially offer a unique opportunity for a range of applications in optics and photonics, biomedical sciences, microfluidics, etc.

AbstractA biocatalytic approach towards a range of 4‐aryloxazolidinones is developed using a halohydrin dehalogenase from Ilumatobacter coccineus (HheG) as biocatalyst. The method is based on the HheG‐catalyzed α‐position regioselective ring‐opening of styrene oxide derivatives with cyanate as a nucleophile, producing the corresponding 4‐aryloxazolidinones in moderate to good yields. Synthesis of enantiopure 4‐aryloxazolidinones is also achievable using chiral epoxide materials.magnified image
Fully Printed, Wireless, Stretchable Implantable Biosystem toward Batteryless, Real‐Time Monitoring of Cerebral Aneurysm Hemodynamics

Published: August 2019

AbstractThis study introduces a high‐throughput, large‐scale manufacturing method that uses aerosol jet 3D printing for a fully printed stretchable, wireless electronics. A comprehensive study of nanoink preparation and parameter optimization enables a low‐profile, multilayer printing of a high‐performance, capacitance flow sensor. The core printing process involves direct, microstructured patterning of biocompatible silver nanoparticles and polyimide. The optimized fabrication approach allows for transfer of highly conductive, patterned silver nanoparticle films to a soft elastomeric substrate. Stretchable mechanics modeling and seamless integration with an implantable stent display a highly stretchable and flexible sensor, deployable by a catheter for extremely low‐profile, conformal insertion in a blood vessel. Optimization of a transient, wireless inductive coupling method allows for wireless detection of biomimetic cerebral aneurysm hemodynamics with the maximum readout distance of 6 cm through meat. In vitro demonstrations include wireless monitoring of flow rates (0.05–1 m s−1) in highly contoured and narrow human neurovascular models. Collectively, this work shows the potential of the printed biosystem to offer a high throughput, additive manufacturing of stretchable electronics with advances toward batteryless, real‐time wireless monitoring of cerebral aneurysm hemodynamics.
Intermolecular 1,4‐Carboamination of Conjugated Dienes Enabled by Cp*RhIII‐Catalyzed C−H Activation

Published: August 2019

AbstractA protocol for the three‐component 1,4‐carboamination of dienes is described. Synthetically versatile Weinreb amides were coupled with 1,3‐dienes and readily available dioxazolones as the nitrogen source using [Cp*RhCl2]2‐catalyzed C−H activation to deliver the 1,4‐carboaminated products. This transformation proceeds under mild reaction conditions and affords the products with high levels of regio‐ andE‐selectivity. Mechanistic investigations suggest an intermediate RhIII–allyl species is trapped by an electrophilic amidation reagent in a redox‐neutral fashion.
