Authors: Juberías Gracia Guillermo , Juan García Natalia 
Published: January 2022

Resumen: Las pequeñas ciudades de las zonas despobladas de España buscan actualmente formas de promocionar su patrimonio cultural en su intento de crear riqueza. La ciudad natal de Francisco de Goya -Fuendetodos, en la región de Zaragoza, España- alberga un importante conjunto de arte público que no ha sido analizado hasta ahora. Nuestro propósito es examinar la evolución histórica del arte público en esta localidad desde la erección del Monumento a Goya del artista Julio Antonio en 1920 -un hito importante en la historia del arte público español- hasta la creación del Museo de Arte Callejero Goya, un museo de arte urbano al aire libre que se extiende por todo el pueblo. Nuestro trabajo de investigación se basa en material periodístico, así como en documentación de archivo y fotografías, para dar cuenta de la historia de los monumentos y murales urbanos de Fuendetodos. El análisis del trabajo de campo realizado in situ revela el potencial de este pueblo, ya que su colección de arte contemporáneo al aire libre puede servir para revitalizar la zona y ayudar en la lucha contra la despoblación.

Abstract: Small towns in Spain’s depopulated areas are currently seeking ways to promote their cultural heritage in their bid to create wealth. Francisco de Goya’s birthplace—Fuendetodos in the region of Zaragoza, Spain—holds a significant ensemble of public art which has not been analysed up to now. It is our purpose to examine the historical evolution of public art in this town from the erection of the Monumento a Goya by artist Julio Antonio in 1920—a major landmark in the history of Spain’s public art—to the creation of the Goya Street Art Museum, an open-air urban art museum that extends throughout the village. Our research work is based on newspaper and periodical material as well as archive documentation and photographs in order to render an accurate account of the history of Fuendetodos’ urban monuments and murals. The analysis of the fieldwork carried out in situ reveals the potential of this town as its collection of open-air contemporary art may serve to revitalize the area and assist in the struggle against depopulation.

Reseña. Emigrar después de la crisis. Crecimiento económico y nueva migración española
Authors: Jiménez Guijarro Susana 
Published: January 2022

Resumen: La obra aquí reseñada nos aproxima, de la mano de Ana Fernández Asperilla y Susana Alba, al que podría ser el primer trabajo centrado en el fenómeno migratorio sucedido tras la Gran Recesión (2008-2013) vivida en España. Además, las autoras tratan de romper con los mitos y clichés que alrededor de la temática migratoria se han forjado entorno a este periodo. Asimismo tratan de desmenuzar las condiciones sociolaborales y los rasgos de las políticas públicas con las que se encuentran los emigrados al exterior de España incluso en la actualidad, contexto temporal que podríamos caracterizar de relativa bonanza económica tras la crisis financiera iniciada en 2008.

Ejemplo de custodia del territorio en Teruel (España): el caso de Mas Blanco y Recartografías
Authors: Sánchez-Murciano María 
Published: January 2022

Resumen: Vivimos rodeados de elementos que naturales y antrópicos que tienen un valor por sí mismos, y que merecen un cuidado y protección para mantenerse a lo largo del tiempo, a salvo de una posible degradación. La custodia del territorio aparece como una herramienta más en este sentido, si bien con el añadido de permitir la gestión privada. Esto significa que, mediante su uso, la sociedad puede llegar a espacios o elementos donde la administración pública no lo hace. La formalización de un acuerdo de custodia del territorio puede ser verbal o escrito, y tiene lugar entre el propietario de un inmueble, elemento natural o territorio, y la entidad de custodia que se ofrece a gestionarlo. En España encontramos distintas figuras de organización de estos acuerdos. La custodia del territorio se aplica generalmente sobre espacios naturales, de titularidad pública o privada. Y en este ámbito trabaja Recartografías, que se presenta como una asociación cultural sin ánimo de lucro que trabaja mediante contratos de custodia con el ayuntamiento de San Agustín (Teruel), gracias al cual se les cedió durante siete años los edificios comunales de Mas Blanco, masada perteneciente a dicho municipio. El proyecto tenía un doble objetivo: por un lado, evitar la pérdida de los edificios de la masada, destacando entre ellos la escuela; y, por otro lado, recuperar los aprovechamientos comunitarios y otras actividades que tenían lugar, como la agricultura, cada vez más minoritarias. Sin embargo, son pocas las ayudas destinadas a este tipo de proyectos o entidades. Hay subvenciones, sobre todo autonómicas, estatales, y cada vez más, europeas, pero para poder redactar un proyecto aspirante a estas ayudas es necesario un equipo de gente comprometida con la asociación, y este es el segundo hándicap: la falta de recursos humanos. Pero la experiencia de Recartografías nos enseña que es posible llevar a cabo proyectos de recuperación de la memoria histórica a base de constancia y compromiso.

ABSTRACT

Objective
With the shelter-in-place orders implemented during the COVID-19 pandemic, learning experiences abruptly changed from on campus to wholly online. This qualitative study explores the perceptions and attitudes of students as they adapted their study space, study time, and approach to learning.

Methods
One hundred five students enrolled in a doctor of chiropractic program were invited to participate in a survey to understand how shelter-in-place orders during the COVID-19 pandemic influenced their approach to learning. Fifty-two of 105 (49.5%) students completed the survey. The survey asked students to select their primary study strategy from a list of options and then prompted students to explain how the COVID-19 pandemic influenced their study space, use of technology, study time, and metacognitive cycle of planning, monitoring, and evaluating their approach to learning. A Thematic analysis of the participants' responses was performed.

Results
Nearly all study participants described a challenge in adapting their study space, study time, or approach to learning. Respondents reported that the use of technology did not change because assessments and resources were electronic before the pandemic. Respondents who selected high-impact study strategies such as self-quizzing or who demonstrated evidence of well-developed metacognition described a positive approach to learning more frequently than did respondents who selected low-impact study strategies such as repeated reading or who did not show evidence of metacognitive development.

Conclusion
This study presents student perceptions related to promoting and developing self-regulated learning skills. Educators can use this information to understand the adaptations to changes in learning experiences that may promote successful learning.

AbstractPurposeTo evaluate the dosimetric advantages of daily adaptive radiotherapy (DART) in intensity‐modulated proton therapy (IMPT) for high‐risk prostate cancer by comparing estimated doses of the conventional non‐adaptive radiotherapy (NART) that irradiates according to an original treatment plan through the entire treatment and the DART that uses an adaptive treatment plan generated by using daily CT images acquired before each treatment.MethodsTwenty‐three patients with prostate cancer were included. A treatment plan with 63 Gy (relative biological effectiveness (RBE)) in 21 fractions was generated using treatment planning computed tomography (CT) images assuming that all patients had high‐risk prostate cancer for which the clinical target volume (CTV) needs to include prostate and the seminal vesicle (SV) in our treatment protocol. Twenty‐one adaptive treatment plans for each patient (total 483 data sets) were generated using daily CT images, and dose distributions were calculated. Using a 3 mm set‐up uncertainty in the robust optimization, the doses to the CTV, prostate, SV, rectum, and bladder were compared.ResultsEstimated accumulated doses of NART and DART in the 23 patients were 60.81 ± 3.47 Gy (RBE) and 63.24 ± 1.04 Gy (RBE) for CTV D99 (p < 0.01), 62.99 ± 1.28 Gy (RBE) and 63.43 ± 1.33 Gy (RBE) for the prostate D99 (p = 0.2529), and 59.07 ± 5.19 Gy (RBE) and 63.17 ± 1.04 Gy (RBE) for SV D99 (p < 0.001). No significant differences were observed between NART and DART in the estimated accumulated dose for the rectum and bladder.ConclusionCompared with the NART, DART was shown to be a useful approach that can maintain the dose coverage to the target without increasing the dose to the organs at risk (OAR) using the 3 mm set‐up uncertainty in the robust optimization in patients with high‐risk prostate cancer.

AbstractPurposeThe efficiency of protective equipment for the brain has not been verified at the left anterior oblique (LAO) position, which is commonly used in clinical procedures. The purpose of this study was to investigate radiation exposure of the brain in interventional radiology (IR) and the shielding ability of a new protective flap.MethodsWe made a flap that combined a protective cap with a left lateral face shield. The flap was made of tungsten‐containing rubber (TCR). An anthropomorphic head phantom was placed at the physician's position, and air kerma rates (μGy/min and μGy/15s) were measured by electronic dosimeter at three locations: the surface of the left side of the head, and the left and right temporal lobes with the protective cap and the flap in fluoroscopy and cine modes. The X‐ray tube was at the lower left side of the physician, and its angles were LAO60 and LAO60CAU40. The tube voltage (95–125 kV), tube current (4.7–732 mA), and air kerma rate (27.8–1078 mGy/min) were automatically adjusted by the X‐ray system. We obtained the cap and the flap shielding efficiencies.ResultsIn cine mode at LAO60CAU40, the shielding efficiencies on the surface of the left side of the head and left temporal lobe with the cap were 92.6% and 5.1%, respectively, and the corresponding shielding efficiencies with the flap were 92.5% and 86.1%, respectively. The flap can reduce radiation exposure of the brain more than the cap alone.ConclusionsAt the left anterior oblique in interventional radiology, the flap can reduce exposure to the brain.

Published: January 2022

AbstractCoupling sites of nitrogen dopants and intrinsic carbon defects (N/DC) in metal‐free carbon are highly active toward electrocatalytic oxygen reduction reaction (ORR), and yet they are hard to be effectively constructed. Here, a novel synthesis strategy for fabrication of N/DC‐enriched metal‐free carbon from precursors containing metal‐nitrogen moieties (M‐Nx) is reported. During pyrolysis of the precursors, the M‐Nx is in situ converted to endogenous metal oxides (MOx) via a halide‐mediated “bait and switch” mechanism to realize a domain‐confined etching of the carbon matrix around the nitrogen dopants, forming abundant N/DC coupling sites in the final carbon products. The optimized N/DC‐enriched carbon exhibits an outstanding ORR activity and stability with a half‐wave potential of 0.903 V (versus RHE) in 0.1 m KOH solution, outperforming most of the reported metal‐free carbon catalysts. Experimental investigations and theoretical calculations demonstrate an improved electron‐donating ability and optimized binding energies of the N/DC coupling sites toward the ORR intermediates, which are primarily responsible for such an excellent ORR activity. This domain‐confined endogenous MOx etching strategy is also widely applicable to different M‐Nx‐containing precursors as well as different halide mediators, which opens up new possibilities to fabricate metal/nonmetal doped carbon materials enriched with various coupling sites of desired synergistic properties.

AbstractCrystal engineering based on defect passivation with metal ions doped into halide perovskites is of considerable interest for tailoring the photoelectric properties of perovskites. Herein, a simple and robust approach for doping metal ions into a thin all‐inorganic CsPbBr3 perovskite film by employing metal–organic framework nanoparticles is presented. Zeolitic imidazolate framework‐8 nanoparticles, which can adsorb water, are dispersed and embedded in a thin perovskite film. The particles self‐decompose at a certain humidity, releasing Zn2+ ions into nearby perovskite crystals. The Zn2+ ions efficiently passivate the undercoordinated defect sites of the defective perovskite crystals, resulting in environmentally stable and enhanced photoluminescence of the perovskite with a quantum yield of ≈14%, more than 24 times greater than that without nanoparticles. Further, a thin Zn‐doped CsPbBr3 film is employed to fabricate arrays of ultraviolet photodetectors, and ≈90% of the initial photocurrent is maintained over 15 d in RH 60%, facilitating the development of a dual‐mode image sensor using which programmed images are visualized based on both photocurrent and photoluminescence.

AbstractThe number of active sites and their intrinsic activity are key factors in designing high‐performance catalysts for the oxygen evolution reaction (OER). The synthesis, properties, and in‐depth characterization of a homogeneous CoNiFeCu catalyst are reported, demonstrating that multimetal synergistic effects improve the OER kinetics and the intrinsic activity. In situ carbon corrosion and Cu leaching during the OER lead to an enhanced electrochemically active surface area, providing favorable conditions for improved electronic interaction between the constituent metals. After activation, the catalyst exhibits excellent activity with a low overpotential of 291.5 ± 0.5 mV at 10 mA cm−2 and a Tafel slope of 43.9 mV dec−1. It shows superior stability compared to RuO2 in 1 m KOH, which is even preserved for 120 h at 500 mA cm−2 in 7 m KOH at 50 °C. Single particles of this CoNiFeCu after their placement on nanoelectrodes combined with identical location transmission electron microscopy before and after applying cyclic voltammetry are investigated. The improved catalytic performance is due to surface carbon corrosion and Cu leaching. The proposed catalyst design strategy combined with the unique single‐nanoparticle technique contributes to the development and characterization of high‐performance catalysts for electrochemical energy conversion.
NHC‐Catalyzed 1,4‐Elimination in the Dearomative Activation of 3‐Furaldehydes towards (4+2)‐Cycloadditions

Published: January 2022

AbstractA dearomative formal (4+2)‐cycloaddition reaction between 2‐substituted 3‐furaldehydes derivatives and isatins or α,α,α‐trifluoroacetophenones as electrophiles has been established under NHC‐catalysis. This approach utilizes the process of hydrogen chloride 1,4‐elimination leading to a highly reactive NHC‐bound heterocyclic o‐QDM intermediates derived from 3‐furaldehydes, which play a key role in the process. By using this strategy, a series of structurally diverse 6,7‐dihydro‐4H‐furo[3,2‐c]pyran‐4‐ones was prepared in 41–85% yields. In addition, the potential of the obtained (4+2)‐cycloadducts has been confirmed in the synthesis of interesting class of spirooxindole derivative containing 6,7‐dihydro‐4H‐furo[3,2‐c]pyran scaffold.magnified image

Published: January 2022

AbstractSite‐selective C(sp3)‐H alkenylation was achieved under photo‐irradiation in the presence of a catalytic amount of decatungstate anion, W10O324−. In this reaction, the radical addition/β‐scission sequence is successfully combined with photocatalytic C(sp3)‐H functionalization. The reaction using weaker C−H bonds such as those in THF revealed that the benzenesulfonyl radical itself underwent HAT directly from the C−H bond, and a decatungstate anion participated in a chain‐repairing step.magnified image
Rye grain response to nitrogen fertilizer and seeding rate
Authors: Noland Reagan L. 
Published: January 2022

AbstractCereal rye (Secale cereale L.) seed production is of increasing value in the United States, yet basic agronomic management practices specific to rye grain production have not been established. Field research trials were conducted near Tifton and Midville, GA, during the winter crop season of 2017–2018 to assess effects of seeding rate and spring‐applied N fertilizer on rye grain production. Cereal rye (cultivar ‘Wrens Abruzzi’) was planted at four seeding rates (215, 323, 431, and 538 seed m−2) and top‐dressed with four spring fertilizer N rates (0, 34, 67, and 101 kg N ha−1) in a randomized complete block design with four replications. At both sites, rye grain yield responses to added N were best described by linear‐plateau regression models. The yield response was greater at Tifton (following corn [Zea mays L.]) than at Midville (following peanuts [Arachis hypogaea L.]), and yield plateaued at 44 and 67 kg N ha−1, respectively. Lodging was increased 31% with the addition of N fertilizer at Midville and also increased quadratically with seeding rate, which presumably contributed to yield reductions at a higher seeding rate (431 seed m−2) across both sites. This work demonstrates the potential to optimize rye grain production with substantially lower seeding rates and fertilizer N inputs than those recommended for other rye end uses (i.e., forage or cover crop) or other winter cereal species.

Published: January 2022

BackgroundAcryloyl chloride is a highly toxic volatile liquid that can cause pulmonary edema. However, no sufficient treatment reports have been published to date. Here, we report a case of acute respiratory distress syndrome (ARDS) caused by acryloyl chloride inhalation.Case presentationThe patient was a 36‐year‐old man with accidental exposure to acryloyl chloride. The patient had dyspnea and wet cough, with approximately 88% percutaneous oxygen saturation at room air. He was diagnosed with ARDS and admitted to the intensive care unit. Initially, he was treated with a high‐flow nasal cannula and sivelestat sodium. However, due to the possibility of delayed exacerbation, the patient was switched to methylprednisolone. Oxygenation gradually improved, and the patient was discharged on the day 8 of hospitalization.ConclusionWe report the case of a patient who developed ARDS with delayed exacerbation after the inhalation of acryloyl chloride, which was treated without endotracheal intubation.
Protein–Protein Communication Mediated by an Antibody‐Responsive DNA Nanodevice**

Published: January 2022

AbstractWe report here the rational design and optimization of an antibody‐responsive, DNA‐based device that enables communication between pairs of otherwise non‐interacting proteins. The device is designed to recognize and bind a specific antibody and, in response, undergo a conformational change that leads to the release of a DNA strand, termed the “translator,” that regulates the activity of a downstream target protein. As proof of principle, we demonstrate antibody‐induced control of the proteins thrombin and Taq DNA polymerase. The resulting strategy is versatile and, in principle, can be easily adapted to control protein–protein communication in artificial regulatory networks.
Nickel‐Catalyzed Desymmetric Reductive Cyclization/Coupling of 1,6‐Dienes: An Enantioselective Approach to Chiral Tertiary Alcohol

Published: January 2022

AbstractWe have developed a nickel‐catalyzed desymmetric reductive cyclization/coupling of 1,6‐dienes. The reaction provides an efficient method for constructing a chiral tertiary alcohol and a quaternary stereocenter by a single operation. The method has excellent diastereoselectivity and high enantioselectivity, a broad substrate scope, as well as good tolerance of functional groups. Preliminary mechanism studies show that alkyl nickel(I) species are involved in the reaction.
Iridium‐Catalyzed Enantioselective and Chemodivergent Allenylic Alkylation of Vinyl Azides for the Synthesis of α‐Allenylic Amides and Ketones**
Authors: Chakrabarty Aditya , Mukherjee Santanu 
Published: January 2022

AbstractThe first enantioselective synthesis of α‐allenylic amides and ketones through allenylic alkylation of vinyl azides is reported. In these chemodivergent reactions, cooperatively catalyzed by a IrI/(phosphoramidite,olefin) complex and Sc(OTf)3, vinyl azides act as the surrogate for both amide enolates and ketone enolates. The desiccant (molecular sieves) plays a crucial role in controlling the chemodivergency of this enantioconvergent and regioselective reaction: Under otherwise identical reaction conditions, the presence of the desiccant led to α‐allenylic amides, while its absence resulted in α‐allenylic ketones. Utilizing racemic allenylic alcohols as the alkylating agent, the overall process represents a dynamic kinetic asymmetric transformation (DyKAT), where both the products are formed with the same absolute configuration. To the best of our knowledge, this is the first example of the use of vinyl azide as the ketone enolate surrogate in an enantioselective transformation.
