Entre la crítica sociopolítica y la utopía artística: el Colectivo de Acciones de Arte (CADA), 1979-1985
Authors: Marchena Sanabria Jorge 
Published: February 2021

El presente ensayo tiene como fin elaborar un breve recorrido por las obras del Colectivo de Acciones de Arte (CADA), presentadas en Chile entre 1979 y 1985; momentos en que la dictadura de Augusto Pinochet se pretendía naturalizar. El CADA destaca, no solo como un ejemplo chileno de arte contemporáneo, sino por su oscilación entre una propuesta de vanguardia –acorde con las tendencias internacionales de la época– y la denuncia política. Precisamente, ante la represión y persecución del régimen y el apagón cultural que estaba experimentando el país, el Colectivo se enfocó en el rescate de la memoria y en la transmisión subrepticia de críticas y mensajes de resistencia. Por ello se analiza la visión que se ha construido en torno a este grupo, rozando con la idealización; proceso que no ha sido adrede. Para la elaboración de este trabajo, se retomaron diversas posturas teóricas en torno al arte contemporáneo, la revisión de artículos de revistas de la época, bibliografía y otros materiales que han sido preservados en torno a las obras que realizó el CADA.
El arte contemporáneo como reflexión social: una aproximación a la obra de Regina José Galindo
Authors: Otárola Guevara Marcela 
Published: February 2021

El arte contemporáneo emerge en el siglo XX y se destaca por el cambio de un paradigma, derivado de una nueva forma de vinculación entre el artista y la sociedad. Para apreciar tal relación, se procede a analizar cualitativamente algunas obras de una exponente de este movimiento, Regina José Galindo, a partir de un cuestionamiento y posterior interpretación sobre las razones que han originado sus producciones. Tal ejercicio requirió estudiar premisas teóricas procedentes de la sociología, la filosofía y la historia del arte. Las piezas seleccionadas refieren a temas asociados a la memoria, la mujer y las relaciones de poder. Además, muestran la empatía y la apropiación espacial como mecanismos de articulación social y revelan los alcances de sus propuestas: exponer a las personas oprimidas, interpelar al espectador y conceder valor al contexto.
Nanostructure and compositional segregation of soft magnetic FeNi‐based nanocomposites with multiple nanocrystalline phases

Published: February 2021

AbstractSoft magnetic metal amorphous nanocomposite alloys are produced through rapid solidification and thermal annealing yielding nanocrystals embedded within an amorphous precursor. Similar free energies in Co‐rich and FeNi‐based alloy systems result in multiple nanocrystalline phases being formed during devitrification. Studies of multi‐phase crystallization processes have been reported for Co‐rich alloys but relatively few have investigated FeNi‐based systems. A detailed characterization of compositional partitioning and microstructure of an optimally annealed FeNi‐based MANC (Fe70Ni30)80Nb4Si2B14 alloy is presented through complementary high‐resolution transmission electron microscopy (HRTEM) and atom probe tomography (APT). HRTEM demonstrates orientation relationships between FCC and BCC nanocrystals, suggesting heterogeneous nucleation of nanocrystals in the amorphous matrix or a cooperative mechanism of nucleation between BCC and FCC nanocrystallites. APT results show evidence for (i) the segregation of Fe and Ni between nanocrystals of different phases, (ii) B partitioning to the amorphous phase, and (iii) an Nb‐enriched shell surrounding nanocrystals.

Published: February 2021

AbstractEmergent behavior at oxide interfaces has driven research in complex oxide films for the past 20 years. Interfaces have been engineered for applications in spintronics, topological quantum computing, and high-speed electronics with properties not observed in bulk materials. Advances in synthesis have made the growth of these interfaces possible, while X-ray photoelectron spectroscopy (XPS) studies have often explained the observed interfacial phenomena. This review discusses leading recent research, focusing on key results and the XPS studies that enabled them. We describe how the in situ integration of synthesis and spectroscopy improves the growth process and accelerates scientific discovery. Specific techniques include determination of interfacial intermixing, valence band alignment, and interfacial charge transfer. A recurring theme is the role that atmospheric exposure plays on material properties, which we highlight in several material systems. We demonstrate how synchrotron studies have answered questions that are impossible in lab-based systems and how to improve such experiments in the future.
Diffusion-mediated chemical concentration variation and void evolution in ion-irradiated NiCoFeCr high-entropy alloy

Published: February 2021

AbstractHigh-entropy alloys (HEAs) are proposed as potential structural materials for advanced nuclear systems, but little is known about the response of matrix chemistry in HEAs upon irradiation. Here, we reveal a substantial change of matrix chemical concentration as a function of irradiation damage (depth) in equiatomic NiCoFeCr HEA irradiated by 3 MeV Ni ions. After ion irradiation, the matrix contains more Fe/Cr in depth shallower than ~900–1000 nm but more Ni/Co from ~900–1000 nm to the end of the ion-damaged region due to the preferential diffusion of vacancies through Fe/Cr. Preferential diffusion also facilitates migration of vacancies from high radiation damage region to low radiation damage region, leading to no void formation below ~900–1000 nm and void formation around the end of the ion-damaged region at a fluence of 5 × 1016 cm−2 (~123 dpa, displacements per atom, peak dose under full cascade mode). As voids grow significantly at an increased fluence (8 × 1016 cm−2, 196 dpa), the matrix concentration does not change dramatically due to new voids formed below ~900–1000 nm.
Probing structural and chemical evolution in (AlxGa1−x)2O3 using atom probe tomography: A review
Authors: Mazumder Baishakhi , Sarker Jith 
Published: February 2021

Abstract(AlxGa1−x)2O3 is a novel ultra‐wide bandgap semiconductor with the potential to dominate future power electronics industries. High‐performance devices demand high Al content in (AlxGa1−x)2O3 but are limited by crystallinity degradation resulting from phase separation. Additionally, the solubility limit of Al is still under debate, and conclusive research is in progress. (AlxGa1−x)2O3 is also limited in high‐frequency applications owing to low carrier mobility and requires n‐type doping. For commercializing this material, the major obstacle is understanding dopant's behavior in the host (AlxGa1−x)2O3. To investigate these issues, an advanced characterization technique, atom probe tomography (APT), was employed to analyze the structural‐chemical evolution of (AlxGa1−x)2O3. In this review, we summarized our recent works on the structure‐chemistry investigation of (AlxGa1−x)2O3 with alloy composition and doping interaction. We introduced machine learning algorithms on APT data to reveal unrivaled knowledge, previously not achievable with conventional methodologies. The outstanding capabilities of APT to study (AlxGa1−x)2O3 with Al composition and doping will be considered significant for the wide bandgap semiconductors community.
A review on the recent advances concerning the fatigue performance of titanium alloys for orthopedic applications
Authors: Campanelli Leonardo Contri 
Published: February 2021

AbstractThis article presents a review on recent advances in the fatigue behavior of Ti alloys, especially the main commercial compositions for orthopedic applications. In the case of well‐known Ti–6Al–4V alloy, the major concern is related to the effect of the surface modification necessary to improve the osseointegration. The introduction of surface discontinuities due to the growth of a porous oxide layer, or the roughness development, may severely affect the fatigue performance depending on the level of alteration. In the case of additive manufactured Ti–6Al–4V, the fatigue response is also influenced by inherent defects of as‐built parts. Regarding the recently developed metastable β alloys, information about the fatigue properties is still scarce and mainly related to the effect of second phase precipitates, which are introduced to optimize the mechanical properties. The fatigue behavior of the Ti alloys is complex, as is their microstructure, and should not be neglected when the alloys are being developed or improved to be applied in medical devices.
VIGOREXIA EM PRATICANTES MASCULINOS DO TREINAMENTO DE FORÇA ENTRE 18-35 ANOS
Authors: Oliveira Fernando Sérgio 
Published: February 2021

O presente estudo teórico buscou aferir a incidência da Vigorexia entre praticantes masculinos do treinamento de força entre 18-35 anos. Nos últimos anos foi diagnosticado um transtorno majoritariamente associado ao sexo masculino chamado Dismorfia Muscular ou Vigorexia que, entre outros aspectos, perturba a vida social, física, mental e psicológica do indivíduo. Essa síndrome caracteriza-se por um quadro onde o indivíduo se vê com um corpo fraco, franzino e pequeno, mas que na verdade não corresponde à realidade, pois sua percepção visual está equivocada. Na verdade, ele é portador de um corpo musculoso, volumoso. Assim, este transtorno se caracteriza por uma exacerbada preocupação em ter o corpo com a maior massa muscular possível. Esta síndrome acomete principalmente os homens jovens, entre 18-35 anos, que buscam no treinamento de força uma “arma” para alcançar o corpo sonhado. A Vigorexia tem muitas causas e ainda não todas esclarecidas, mas é universalmente aceite pelos autores a extraordinária influência da mídia sobre este novo conceito de biótipo físico masculino. Os jovens buscam uma afirmação social através do corpo. Para tal, utilizam substâncias perigosas para a sua saúde como os esteroides anabolizantes. Ao mesmo tempo praticam sessões de treinamento exaustivas na ânsia de obterem músculos maiores levando o corpo à exaustão, além de prejudicarem ossos, ligamentos, tendões e músculos. Outro aspecto muito importante deste transtorno é o psicológico do indivíduo, muito alterado e frequentemente ansioso, principalmente quando associado à utilização de esteroides anabolizantes. Conclui-se no estudo que o problema é crescente e já com uma incidência respeitável e merecedora da atenção dos órgãos públicos para combater este problema. Palavras-chave: Dismorfia Muscular. Imagem Corporal. Treinamento de Força. Mídia. Esteroide Anabolizante.

Published: February 2021

INTRODUÇÃO: O Stand Up Paddle (SUP) ou Hoe He’e Nalu, em havaiano, é um esporte que consiste basicamenteem remar de pé sobre uma prancha. Surgiu no Havaí, por volta de 1960, por surfistas, usavam grande pranchas e remavam nelas, para tirar fotos dos alunos e aspirantes do Surf da época. Mesmo sendo umesporte antigo entrou em evidência há poucos anos, tem como objetivo realizar uma revisão da literatura sobre aspectos atuais e relevantes deste esporte. MATERIAIS E MÉTODOS: Para este trabalho, foi realizada uma pesquisa na base de dados PubMed, em maio de 2018, utilizando como palavra-chave Stand Up Paddle. RESULTADOS: Foram encontrados 09 artigos sobre este tema, sendo todos originais. Dos artigos encontrados: 02 abordavam sobre lesão de praticantes do esporte, 02 artigos tratavam sobre a fisiologia do exercício, com praticantes e atletas de SUP, sobre postura, foram encontrados mais 02 artigos, também foram encontrados 02 artigos que abordavam a composição corporal e apenas 01 artigo, que não é relacionado ao esporte SUP,mas apareceu na pesquisa do banco de dados, bem provavelmente por apresentar a palavra “stand” e “paddle”. CONCLUSÃO: Conclui-se com esse trabalho que existem poucas pesquisas sobre o esporte SUP, cadastradas no banco de dados do Pubmed, mostrando a necessidade de mais estudos sobre as diversas áreas da saúde, para conhecer e compreender a fisiologia, a biomecânica, as lesões e dentre outros desse esporte. Se comparado esse esporte com outros esportes de remo, o SUP é o único que é praticado em pé.
La stabilitÃ© financiÃ¨re des SystÃ¨mes Financiers DÃ©centralisÃ©s (SFD) au SÃ©nÃ©gal : quelle situation aprÃ¨s une nouvelle rÃ©gulation prudentielle ?

Ce travail cherche Ã analyser la stabilitÃ© financiÃ¨re des SFD au SÃ©nÃ©gal Ã travers la soliditÃ© financiÃ¨re et la protection des Ã©pargnants, suite Ã lâ€™application dâ€™une nouvelle rÃ©gulation prudentielle en 2010. La mÃ©thodologie repose sur une base de donnÃ©es de panel de 42 SFD de 2010 Ã 2015. Elle est consolidÃ©e et mise Ã notre disposition par la direction de la rÃ©glementation qui assure la tutelle des SFD. Un traitement de normalisation par la mÃ©thode Â« Min-Max Â», suivi dâ€™une pondÃ©ration et dâ€™une agrÃ©gation par une analyse en composante principale (ACP) ont permis de construire un indice agrÃ©gÃ© de stabilitÃ© et des sous indices pour apprÃ©cier la stabilitÃ© financiÃ¨re. Les rÃ©sultats soulignent une stabilitÃ© financiÃ¨re et de ses dimensions (rentabilitÃ©, qualitÃ© des actifs et protection des actifs). Cependant, des efforts supplÃ©mentaires permettraient de hisser les niveaux de rentabilitÃ©, de diminuer le PAR et de corriger la tendance baissiÃ¨re des indicateurs de la protection des Ã©pargnants. La disponibilitÃ© des donnÃ©es, au-delÃ de 2015, serait une valeur ajoutÃ©e. Il serait important aussi de mieux analyser les dÃ©terminants de la liquiditÃ© de lâ€™actif qui contribue Ã hauteur de 40% Ã la protection des Ã©pargnants.
This work seeks to analyze the financial stability of the Decentralized Financial System(DFS) in Senegal through the financial robustness and protections of savers, after the application of new prudential regulation in 2010. The methodology consists of a database of 42 Decentralized Financial System panels from 2010 to 2015. It is consolidated and made available at our disposal by the Direction of the regulation which assures the guardianship of DFSs. A regulation by the method Â« Min-Max Â», followed by a ponderation and aggregation by a component analysis have permitted to build an aggregated index of stability and sub-indexes to give an appreciation of the financial stability. The results underline financial stability and its dimensions (profitability, quality of assets and assets protection). However, supplementary efforts should be permitted to boost the level of rentability, to increase the PAR and to correct decreased tendency of indicators of the protection of savers. The availability of datas, beyond 2015, should be an added value. It also should be important to better analyze the determinants of asset quality which contributes to the level of 40% to the protection of savers.
Dissensions internes du peuple nâ€™zima kotoko et pratique de lâ€™abissa a grand-bassam dans le sud de la CÃ´te dâ€™Ivoire

Published: February 2021

Institution traditionnelle de cohÃ©sion sociale, lâ€™Abissa reprÃ©sente pour la sociÃ©tÃ© Nâ€™Zima le socle des valeurs. Il marque le dÃ©but du nouvel an consacrÃ© Ã la critique sociale, Ã la purification et au renforcement des liens communautaires et sociaux. Cependant, fort des dissensions internes qui apparaissent en 2018, une rupture dans sa pratique sâ€™est observÃ©e. Le prÃ©sent article se propose alors de comprendre comment les dissensions internes du peuple Nâ€™zima affectent la pratique de lâ€™Abissa ainsi que les consÃ©quences qui en dÃ©coulent. Pour ce faire, lâ€™entretien et lâ€™observation ont Ã©tÃ© mobilisÃ©s comme techniques. Lâ€™enquÃªte a mis en lumiÃ¨re lâ€™intrusion des tiers dans la pratique de lâ€™Abissa et les dissensions politiques comme facteurs de rupture. En effet, lâ€™interventionnisme des pouvoirs dans la fixation des dates des festivitÃ©s de lâ€™Abissa sont interprÃ©tÃ©es par une frange ultra-conservatrice de la population comme un acte de dÃ©sacralisation. A ce facteur, sâ€™ajoute la position politique jugÃ©e partisane du souverain Nâ€™zima qui a exacerbÃ© des tensions sociales et communautaires dÃ©jÃ assez fortes dans un contexte Ã©lectoral cristallisÃ© par la violence. Comme consÃ©quences de cette situation confligÃ¨ne, la profanation de lâ€™Abissa avec son corollaire la perturbation des Ã©nergies cosmiques en faveur du peuple, de mÃªme que la fragilisation des relations sociales se soldant par la rÃ©currence des conflits intercommunautaires. La comprÃ©hension du phÃ©nomÃ¨ne sâ€™est faite Ã partir la thÃ©orie des parties prenantes (J.D. Rendtoff, M. Bonnafous-Boucher, 2014) qui permet Ã partir de leur positionnement dans les actions dâ€™identifier les acteurs en confrontation et les logiques de leurs actions.

Published: February 2021

In intensive shrimp culture, oxygen consumption of shrimp is an important indicator that greatly affects the physiological condition of shrimp as a reared organism. The purpose of this study was to dynamically determine the oxygen consumption of shrimp in intensive culture as well as the variables of water quality and shrimp growth. This research was conducted with the concept of ex-post facto causal design in intensive aquaculture ponds during the shrimp cultivation period. During the shrimp culture period, the rate of oxygen consumption of shrimp is inversely related with the sigmodial average increase in shrimp body weight. Meanwhile, based on the simulation analysis with the dynamic modeling concept, it is shown that oxygen consumption was linear to the dynamics of average daily gain and inversely proportional with the increasing rate of shrimp biomass in the ponds. In addition, oxygen consumption rate of shrimp in intensive ponds had a close relationship with water salinity and total organic matter. In conclusion, dynamically, the fluctuation of oxygen consumption rate and average daily gain of shrimp in intensive culture are closely related to the stability of the water quality conditions on the shrimp habitat.
