Economía informal y perspectiva de género en contextos de trabajo (A. Téllez Infantes; J. Eloy Martínez Guirao, Eds.)
Authors: Bereményi Bálint Ábel
Published: February 2022

La economía informal ocupa su lugar en los modelos económicos desde hace relativamente poco. Desde los inicios de los setenta se ha acumulado un cuerpo significativo de trabajos científicos sobre este elemento clave de la organización de recursos y su incidencia en la estructura social. La informalidad, sin embargo, nunca se ha definido de forma independiente, más bien se ha abordado desde los modelos económicos dominantes de diversos momentos históricos. Hasta bien entrados los ochenta, el estudio de la informalidad en la economía se centró en países o territorios subdesarrollados y en las clases sociales desfavorecidas. A finales de los ochenta, sin embargo, se amplía el foco para abarcar la gran heterogeneidad del sector informal. Gracias a esta apertura la clase social, las migraciones intraterritoriales y transnacionales así como las relaciones de género comenzaron a ser dimensiones transversales del análisis sobre la economía informal.
Madres solteras por elección: entre el “engaño” y la solidaridad
Authors: Jociles María Isabel , Rivas Ana María , Moncó Beatriz , Villaamil Fernando
Published: February 2022

En este artículo se analizan los discursos sobre las motivaciones que las Madres Solteras por Elección (MSPE) aducen para optar, o no, por las diferentes vías de acceso a la monoparentalidad electiva que ellas mismas distinguen: la que denominan “el engaño”, esto es, la fecundación sexual planificada pero no declarada, la fecundación sexual mediante “donante conocido”, la fecundación asistida y la adopción internacional. Estos discursos, producidos tanto en entrevistas cualitativas como en otros contextos de interacción (foros de Internet, kedadas, reuniones de amigas, etc.), han sido objeto de observación en el contexto de una investigación etnográfica realizada en la Comunidad de Madrid (España) durante el periodo 2008-2009. Dichos discursos ponen de manifiesto, en primer lugar, que las MSPE manejan una gran variedad de concepciones acerca de la maternidad y el vínculo materno-filial. Estas condiciones fundamentan las “motivaciones”, asimismo diversas, que alegan para justificar la opción que han escogido. En segundo lugar, que su toma de decisiones está mediada por la existencia de una jerarquía socio-moral entre las distintas vías de acceso a la maternidad en solitario, cuyas posiciones más bajas están ocupadas por “el engaño” y “el donante conocido”, y la más elevada, por la adopción internacional. Se concluye subrayando la idea de que los enunciados de valor en que se basa dicha jerarquía socio-moral explican la pervivencia de la “motivación de la solidaridad” en el discurso de las MSPE adoptantes, a pesar de la deslegitimación de que es objeto por parte del conocimiento experto sobre el tema.

«Huarpes no tan huarpes» y «hombres modernos»: interpelaciones étnicas y disputas por las últimas tierras irrigadas en Mendoza (Argentina)
Authors: Saldi Leticia
Published: February 2022

A través de un estudio etnográfico en la periferia del oasis de riego más importante del centro-oeste argentino, se analiza la intervención de persistentes representaciones étnico-raciales y ambientales en la delimitación de áreas irrigadas y de grupos sociales que ostentan la tenencia del agua y la tierra. Los grupos situados a uno y otro lado de los últimos canales de riego son interpelados desde paradigmas modernistas que vinculan a la tenencia del agua, la propiedad privada y la producción vitivinícola con la herencia europea y la idea de progreso, mientras que lo no irrigado, la tenencia comunitaria de la tierra y el pastoreo trashumante se asocia a la descendencia indígena huarpe y a la idea de atraso o involución. Debido a la presencia de dos espacios y grupos socio-culturales supuestamente autónomos, opuestos y separados por los últimos canales de riego es que se los conceptualiza como frontera hídrica. Esta, a pesar de ser considerada como natural y fija, es por el contrario artificial y dinámica, producto de luchas sociales y simbólicas por el agua y por la obtención de legitimidad como grupo socio-cultural capaz de obtenerla y controlarla. Asimismo se resaltan la presencia no solo de actores liminales, ni huarpes ni de origen europeo, sino también de alianzas que pueden llevar a la reconfiguración de espacios irrigados y de grupos socioculturales capaces de dar batalla en las disputas por los recursos naturales.
Relatedness in Assisted Reproduction. Families, Origins and Identities, de Tabitha Freeman, Susanna Graham, Fatemeh Ebtehaj y Martin Richards (Eds.)
Authors: Alvarez Bruna
Published: February 2022

Las técnicas de reproducción asistida (TRA) con donantes, receptores y subrogación, se han ido perfeccionando desde que en 1978 nacía la primera niña por fertilización in vitro (FIV) en el Reino Unido, a la vez que ha aumentado el número de personas que recurren a ellas para tener hijos o hijas. Estas nuevas y diversas formas de reproducirse han hecho surgir nuevos planteamientos referentes al parentesco y la filiación, al mismo tiempo que han diversificado las opciones en las decisiones reproductivas.
Actores sociales, violencias y luchas de emancipación. Lecturas desde una antropología crítica, de Margarita del Carmen ZáraTe Vidal y María Gabriela Hita (Coords.)
Authors: Reyes García Héctor Adrián
Published: February 2022

Actores sociales, violencias y luchas de emancipación es un libro que voltea la tuerca. Se distancia de un análisis del orden sistémico basado en la lucha entre contrarios para aproximarse a las acciones, reacciones y enfrentamientos que efectúan las personas involucradas en las situaciones de violencia. Las aristas se posicionan en el plano geográfi co: se lleva al lector a América Latina (Brasil, Guatemala, México y Colombia) para terminar cayendo en Indonesia. En el texto la violencia se apodera de lo cotidiano, de las acciones y reacciones de quien la enfrenta.

Como si de un proceso evolutivo se tratase, el desarrollo y crecimiento de una revista científica también sigue una senda de cambios para adaptarse al entorno en el que vive. Por fortuna, en nuestro caso el entorno no es una naturaleza incierta ni hostil, sino un gran grupo social definido por los y las miles de lectores que desde hace ya catorce años nos siguen acogiendo y apoyando. Es por eso que el presente número de la revista, aunque algo más breve en contenidos que los números anteriores, emprende su marcha a través de uno de los retos «adaptativos» más ambiciosos llevados a cabo por una publicación periódica de antropología en acceso abierto. Este reto es la publicación de los textos íntegros de nuestros artículos en idioma inglés. En el momento de escribir estas líneas, un total de cuatro traductores, pertenecientes al Departamento de Lenguas Modernas en The State University of New York at Potsdam, están preparando la versión inglesa del número, que estará disponible dentro de los cinco próximos meses después de la aparición en su versión en castellano.
El olor del cuerpo migrante en la ciudad desodorizada. Simbolismo olfativo en los procesos de clasificación social
Authors: Mata-Codesal Diana
Published: February 2022

El simbolismo olfatorio está presente en procesos sociales de clasificación. El olor se utiliza como marcaje de subalteridad en los procesos de diferenciación y evitación del inmigrante en la ciudad, un otro inferior que «huele mal». A partir del ejemplo etnográfico del barrio de El Carmel en la ciudad de Barcelona, este texto analiza la odoro-socialidad relacionada con la construcción del «cuerpo del inmigrante», en el que confluyen tanto consideraciones de otredad y externalidad como de marginalidad. Estos procesos solo pueden entenderse a la luz de la existencia de relaciones de poder concretas que cristalizan en regímenes de aceptabilidad social específicos. Este artículo muestra cómo la presencia de solo algunos olores se construye como una anomalía molesta en el supuestamente desodorizado entorno urbano de Barcelona, espacio que en realidad ofrece un complejo paisaje olfativo sujeto a lógicas de mercantilización. Reflexionar sobre el papel del olor en los mecanismos de clasificación social nos permite acercarnos de una manera encarnada a los procesos de sociabilidad que tienen lugar en espacios urbanos supuestamente inodoros, así como analizar procesos de corporalización de tensiones entre identidad-alteridad
«Yo allí soy feliz, voy de lunes a viernes sin faltar»: Reflexiones desde una etnografía escolar en una cárcel de mujeres
Authors: Osuna Nevado Carmen
Published: February 2022

Este artículo se basa en un trabajo de campo realizado en el Centro de Educación para Personas Adultas de una cárcel de mujeres. El objetivo es mostrar el modo en que ambas instituciones se imbrican y colisionan, subrayando las contradicciones entre una legislación que fomenta la educación escolar y unas lógicas de funcionamiento que la dificultan. Las narrativas de las mujeres que asisten a la escuela se convierten en ejes articuladores de unas conclusiones que presentan las aulas como un lugar en el que reconectar con su vida fuera de los muros y resignificar su estancia en prisión.
Transport of complex and active fluids in porous media
Authors: Kumar Manish , Guasto Jeffrey S. , Ardekani Arezoo M.
Published: February 2022

Complex and active fluids find broad applications in flows through porous materials. Nontrivial rheology can couple to porous microstructure leading to surprising flow patterns and associated transport properties in geophysical, biological, and industrial systems. Viscoelastic instabilities are highly sensitive to pore geometry and can give rise to chaotic velocity fluctuations. A number of recent studies have begun to untangle how the pore-scale geometry influences the sample-scale flow topology and the resulting dispersive transport properties of these complex systems. Beyond classical rheological properties, active colloids and swimming cells exhibit a range of unique properties, including reduced effective viscosity, collective motion, and random walks, that present novel challenges to understanding their mechanics and transport in porous media flows. This review article aims to provide a brief overview of essential, fundamental concepts followed by an in-depth summary of recent developments in this rapidly evolving field. The chosen topics are motivated by applications, and new opportunities for discovery are highlighted.
Rheology of stiff-chain polymer solutions
Authors: Sato Takahiro
Published: February 2022

Theoretical expressions for the intrinsic viscosity, the Huggins coefficient, zero-shear viscosity, and storage and loss moduli for stiff-chain polymer solutions are reviewed. Especially, the mean-field Green function method is explained in detail to consider the intermolecular collision effect on the rheological properties of concentrated stiff-chain polymer solutions, by applying the method to monodisperse and polydisperse straight cylinders and monodisperse fuzzy cylinder models. The theoretical expressions reviewed are compared with experimental results for aqueous solutions of two rigid helical polysaccharides, schizophyllan and xanthan.

Published: February 2022

Purpose:To describe the Dynamic Exertion Test (EXiT) by comparing physiological, performance, and clinical outcomes between athletes medically cleared following sport-related concussion (SRC) and healthy controls.Methods:One hundred four (female = 41, 39.4%) participants (14–21 y of age) including 52 medically cleared for return to play at 21.48 (15.40) days following SRC and 52 healthy athletes completed the EXiT involving (1) 12-minute aerobic component and (2) 18-minute dynamic component including 2 functional movement and 5 change-of-direction (COD) tasks. Physiological (heart rate and blood pressure), clinical (endorsed symptoms and rating of perceived exertion), and performance (COD-task completion time and errors) outcomes were collected throughout EXiT. Participants also completed the Postconcussion Symptom Scale and vestibular/ocular motor screening before EXiT. Independent-samplesttests were used to compare groups on resting heart rate and blood pressure, COD-task completion time, and Mann–WhitneyUtests on Postconcussion Symptom Scale, vestibular/ocular motor screening, and EXiT symptoms, rating of perceived exertion, and errors.Results:COD-task completion time and resting systolic blood pressure and heart rate were similar between groups (P > .05). SRC reported greater rating of perceived exertion during the aerobic component (P < .05) and lower total dizziness (P = .003) and total symptoms (P = .021) during EXiT and had lower near point of convergence distance (P < .001) and total symptoms (P = .007) for vestibular/ocular motor screening than healthy athletes.Conclusion:Physiological, performance, and clinical EXiT outcomes were equivocal between athletes at medical clearance following SRC and healthy controls. The multidomain EXiT may help to inform safe return-to-play decision making post-SRC.
Toward a Sport Ecosystem Logic
Authors: Buser Markus , Woratschek Herbert , Dickson Geoff , Schönberner Jan
Published: February 2022

Network approaches in sport management are mainly guided by the logic of sport products, where firms produce value that is used-up by consumers. This logic neglects the collaborative nature of sport. On the contrary, the logic of value co-creation provides a perspective where actors collaborate to co-create value in sport networks. Thus, this purely conceptual research aims to examine approaches to value co-creation in sport ecosystems to offer a holistic perspective on the interconnectedness of actors and engagement platforms. Using the concepts of value co-creation, engagement platforms, and sport network approaches, this paper conceptualizes the Sport Ecosystem Logic as a general theory to promote innovative research. Comprising five fundamental premises, the Sport Ecosystem Logic explains how actors’ shared interests in sporting activities evolve into an entire sport ecosystem. The Sport Ecosystem Logic advances our understanding of actors’ resource integration on sport engagement platforms and how these platforms are interconnected in a sport ecosystem.

Published: February 2022

Relative crustal motions along active faults generate earthquakes, and repeated earthquake cycles build mountain ranges over millions of years. However, the long-term summation of elastic, earthquake-related deformation cannot produce the deformation recorded within the rock record. Here, we provide an explanation for this discrepancy by showing that increases in strain facilitated by plastic deformation of Earth’s crust during the earthquake cycle, in conjunction with isostatic deflection and erosion, transform relative fault motions that produce individual earthquakes to geologic deformations. We focus our study on the data-rich Santa Cruz Mountains, CA, USA and compare predicted and observed quantities for rock uplift, apatite (U-Th)/He thermochronology, topographic relief,

Be-based erosion rates, and interseismic surface velocities. This approach reconciles these disparate records of mountain-building processes, allowing us to explicitly bridge decadal measures of deformation with that produced by millions of years of plate motion.

Surface cleaning using commercial disinfectants, which has recently increased during the coronavirus disease 2019 pandemic, can generate secondary indoor pollutants both in gas and aerosol phases. It can also affect indoor air quality and health, especially for workers repeatedly exposed to disinfectants. Here, we cleaned the floor of a mechanically ventilated office room using a commercial cleaner while concurrently measuring gas-phase precursors, oxidants, radicals, secondary oxidation products, and aerosols in real-time; these were detected within minutes after cleaner application. During cleaning, indoor monoterpene concentrations exceeded outdoor concentrations by two orders of magnitude, increasing the rate of ozonolysis under low (<10 ppb) ozone levels. High number concentrations of freshly nucleated sub–10-nm particles (≥10

Published: February 2022

During pandemics, effective nonpharmaceutical interventions encourage people to adjust their behavior in fast-changing environments in which exponential dynamics aggravate the conflict between the individual benefits of risk-taking and its social costs. Policy-makers need to know which interventions are most likely to promote socially advantageous behaviors. We designed a tool for initial evaluations of the effectiveness of large-scale interventions, the transmission game framework, which integrates simulations of outbreak dynamics into large-group experiments with monetary stakes. In two studies (
n
= 700), we found substantial differences in the effectiveness of five behavioral interventions. A simple injunctive-norms message proved most effective, followed by two interventions boosting participants’ ability to anticipate the consequences of risky behavior. Interventions featuring descriptive norms or concurrent risk information failed to reduce risk-taking.
Stimulus-responsive room temperature phosphorescence materials with full-color tunability from pure organic amorphous polymers

Published: February 2022

Achieving stimulus-responsive ultralong room temperature phosphorescence (RTP) in organic materials especially with full-color tunable emissions is attractive and important but rarely reported. Here, a strategy was reported to realize stimulus-responsive RTP effect with color-tunable emissions by using water as solvent in the preparation process without any organic solvent through covalent linkage of arylboronic acids with different π conjugations and polymer matrix of polyvinyl alcohol. The yielded polymer films exhibit outstanding RTP performance (2.43 s). Furthermore, an excitation-dependent RTP film was obtained, and the afterglow color changes from blue to green, then to red as the excitation wavelength increases. The RTP property of all the above materials is sensitive to water and heat stimuli, because the rigidity of the system could be broken by water. Last, they were successfully applied in a multilevel information encryption and multicolor paper and ink.
Decrypting the polymetamorphic record of the Himalaya

Published: February 2022

Reconstructions of the tectonometamorphic architectures of orogenic systems rely on petrogenetic indicator minerals, such as garnet, to trace the transport of rocks through space and time. We show the results of new garnet Lu–Hf geochronology and inclusion U-(Th-)Pb geochronology from exhumed midcrustal metamorphic rocks exposed in the Kanchenjunga region of the eastern Nepalese Himalaya. Garnet in three of the five specimens analyzed yielded pre-Himalayan Lu–Hf dates of ca. 292–230 Ma, which contrasts with Himalayan-aged inclusions therein. Garnet in these specimens either grew entirely during the Early Permian opening of the Neo-Tethys Ocean or grew partly during Cambrian–Ordovician orogenesis and partly during the Cenozoic. The remaining two specimens yield Lu–Hf ages of ca. 50 Ma, which are some of the oldest recorded dates for Himalayan metamorphism. The apparent discordance between the geochronological techniques highlights a potential issue with interpretations that rely on single-geochron-method inclusion records. These results further show that some pressure-temperature determinations used in Himalayan models may not be Himalayan in age.
Calibrating the Russøya excursion in Svalbard, Norway, and implications for Neoproterozoic chronology

Published: February 2022

The Tonian–Ediacaran Hecla Hoek succession of Svalbard, Norway, represents one of the most complete and well-preserved Neoproterozoic sedimentary successions worldwide. With diverse fossil assemblages, an extensive carbonate δ13C record, and sedimentary evidence for two distinct Cryogenian glaciations, this succession will continue to yield insights into the Neoproterozoic Earth system; however, at present there are no direct radiometric age constraints for these strata. We present two new Re-Os ages and initial Os isotope data that constrain the timing of Neoproterozoic glaciation in Svalbard, providing further support for two globally synchronous Cryogenian glaciations and insight into pre- and post-snowball global weathering conditions. An age from the Russøya Member (Elbobreen Formation) facilitates correlation of the negative carbon isotope excursion recorded therein with the pre-glacial “Islay” excursion of the Callison Lake Formation of northwestern Canada and the Didikama and Matheos Formations of Ethiopia. We propose that this globally synchronous ca. 735 Ma carbon isotope excursion be referred to as the Russøya excursion with northeastern Svalbard as the type locality. This new age provides an opportunity to construct a time-calibrated geological framework in Svalbard to assess connections between biogeochemical cycling, evolutionary innovations within the eukaryotes, and the most extreme climatic changes in Earth history.
Giant sheath-folded nappe stack demonstrates extreme subhorizontal shear strain in an Archean orogen
Authors: Zhong Yating , Kusky Timothy M. , Wang Lu
Published: February 2022

Giant sheath-folded nappes are associated with suture zones and emplacement of far-traveled allochthons in Phanerozoic orogens, demonstrating a rare but significant geologic phenomenon indicative of modern-style plate tectonics. We document the world's oldest-known subhorizontal mega-scale sheath fold from Archean Alpine-style nappes of the Central orogenic belt, North China craton. The Zanhuang nappes are recumbent Alpine-style forearc-affinity metabasaltic and metasedimentary nappes emplaced over a passive continental margin in the Archean, marking an ancient suture zone. Field evidence shows multiscale sheath folds from decimeters to tens of meters in size, and our three-dimensional fence profile, fold hinges, kinematic lineations, and lithological traces define an ~1-km-long (parallel to the x-axis) sheath fold in the core of the nappe stack. Structural analysis statistically demonstrates the macro-scale recumbent sheath-folded nappe preserves a complete 180° hinge-line curvature. The giant sheath fold plunges northwest, reflecting its formation during non-coaxial, top-to-the-southeast shearing with extremely high shear strain (γ ≥10), equated to >10 km of ductile slip on the bounding surfaces. Slip vectors derived from S-C fabrics on overturned limbs are consistent with rotation into the southeast-directed transport direction, parallel to the similarly rotated fold hinges. Comparison of the giant sheath-folded nappes from the Archean Zanhuang example with mega-scale sheath folds in Phanerozoic and Proterozoic orogens shows that Neoarchean lithosphere was stiff enough to allow tectonics to operate in a manner analogous to modern-style plate tectonics.
Zn-, Mg- and O-isotope evidence for the origin of mantle eclogites from Roberts Victor kimberlite (Kaapvaal Craton, South Africa)
Authors: Huang Jian , Huang Jin-Xiang , Griffin William L. , Huang Fang
Published: February 2022

We report Zn-isotope compositions of garnet, clinopyroxene, and whole rocks for 14 Type I and 10 Type II eclogites from the Roberts Victor kimberlite (Kaapvaal Craton, South Africa) that were previously analyzed for Mg-O isotopes. Type II eclogites are the protoliths of the highly metasomatized Type I. Garnet and clinopyroxene in Type II eclogites have δ66Zn from 0.14‰ to 0.50‰ and from 0.29‰ to 0.58‰, respectively; reconstructed whole-rock δ66Zn is from 0.24‰ to 0.54‰, which is higher than typical mantle values (0.16–0.20‰). Their heavy Zn- and light Mg- and O-isotope compositions (δ26Mg = −1.1‰ to −0.14‰, δ18O = 2.3‰ to 4.9‰) cannot originate from subducted, carbonate-rich, altered oceanic crust, which is enriched in heavy Zn-O and light Mg isotopes. The low δ18O may be inherited from parental melts derived from low-δ18O mantle sources like those that produced the Weltevreden komatiites of the Kaapvaal Craton. The high δ66Zn and low δ26Mg reflect diffusion-driven Zn-Mg–isotope exchange between peridotites and the parental melts during their emplacement in the deep lithosphere. Type I eclogites have reconstructed whole-rock δ66Zn from 0.03‰ to 0.43‰ and garnet δ18O from 6‰ to 9.1‰ but show more scatter in inter-mineral Zn-isotope fractionation than Type II, reflecting incomplete equilibration during later metasomatism by carbonatitic-to-kimberlitic melts. Our evidence from multiple isotopes thus suggests that the Roberts Victor eclogites might have crystallized from deep-seated melts at mantle depths.
Thyrotoxic periodic paralysis (TPP): assessment in the emergency department
Authors: Mahon-Daly Freyia , Liegeois Claire , Carter John-Paul
Published: February 2022

A male patient aged in his early twenties presented to the emergency department (ED) with quadriparesis. He was ordinarily fit and well and had exercised and eaten a carbohydrate rich meal the evening before. His point-of-care venous blood sample on arrival to the ED showed hypokalaemia of 1.6 mmol/L. (normal range=3.5–5.0 mmol/L). He was put on a cardiac monitor and started on an intravenous infusion of potassium chloride. With the benefit of hindsight, his male sex, particular features in his history and his initial ECG all pointed to a differential diagnosis of thyrotoxic periodic paralysis (TPP), although a differential diagnosis of a first attack of familial hypokalaemic paralysis was considered. As urgent thyroid function tests were sent promptly, there was minimal delay in reaching a diagnosis of TPP and promptly starting propranolol as a safe and more effective means of reversing TPP, followed by definitive treatment with carbimazole.
Functional movement disorder gender, age and phenotype study: a systematic review and individual patient meta-analysis of 4905 cases
Authors: Lidstone Sarah C. , Costa-Parke Michael , Robinson Emily J. , Ercoli Tommaso , Stone Jon
Published: February 2022

Functional movement disorder (FMD) is a common manifestation of functional neurological disorder presenting with diverse phenotypes such as tremor, weakness and gait disorder. Our current understanding of the basic epidemiological features of this condition is unclear. We aimed to describe and examine the relationship between age at onset, phenotype and gender in FMD in a large meta-analysis of published and unpublished individual patient cases. An electronic search of PubMed was conducted for studies from 1968 to 2019 according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Individual patient data were collected through a research network. We described the distribution of age of onset and how this varied by gender and motor phenotype. A one-stage meta-analysis was performed using multilevel mixed-effects linear regression, including random intercepts for country and data source. A total of 4905 individual cases were analysed (72.6% woman). The mean age at onset was 39.6 years (SD 16.1). Women had a significantly earlier age of onset than men (39.1 years vs 41.0 years). Mixed FMD (23.1%), tremor (21.6%) and weakness (18.1%) were the most common phenotypes. Compared with tremor (40.7 years), the mean ages at onset of dystonia (34.5 years) and weakness (36.4 years) were significantly younger, while gait disorders (43.2 years) had a significantly later age at onset. The interaction between gender and phenotype was not significant. FMD peaks in midlife with varying effects of gender on age at onset and phenotype. The data gives some support to ‘lumping’ FMD as a unitary disorder but also highlights the value in ‘splitting’ into individual phenotypes where relevant.
Clinical efficacy and safety of two concentrations of intravenous nicardipine hydrochloride for nicardipine-related phlebitis in patients with preeclampsia
Authors: Ye Fengying , Lu Qiuyun , Kong Bihua , Li Yanqiu
Published: February 2022

To evaluate the effect of two concentrations of intravenous administration of nicardipine hydrochloride on nicardipine-related phlebitis in patients with preeclampsia. A total of 100 preeclampsia patients were administered with nicardipine hydrochloride and divided into the low-concentration (LC) and high-concentration (HC) groups. The incidence and severity of phlebitis, time from treatment to onset of phlebitis, skin temperature, visual analogue scale (VAS) score, induration, and systemic adverse reactions were compared between two groups. The incidence rate of phlebitis in the LC group was 20% (10/50), significantly lower than 42% (21/50) in the HC group (P < 0.05). Ridit Analysis showed that the severity of phlebitis in the LC group was remarkably lower than that in the HC group (P < 0.05). In the LC group, the time from intravenous administration to onset of phlebitis was longer, the average skin temperature was higher, the VAS score was lower, and the indurated area was smaller than those in the HC group (all P < 0.05). Intravenous infusion of nicardipine hydrochloride with constant and low concentration reduces the incidence rate of phlebitis, prolongs the time from treatment to onset of phlebitis, alleviates the severity of phlebitis and pain, maintains skin temperature, and minimizes induration in preeclampsia patients without systemic adverse reactions.

Rational, recognizable, and aperiodic partially lossy queue languages
Authors: Köcher Chris
Published: February 2022

Partially lossy queue monoids (plq monoids) model the behavior of queues that can non-deterministically forget specified parts of their content at any time. We call the subsets of this monoid partially lossy queue languages (plq languages). While many decision problems on recognizable plq languages are decidable, most of them are undecidable if the languages are rational. In particular, in this monoid the classes of rational and recognizable languages do not coincide. This is due to the fact that the class of recognizable plq languages is not closed under multiplication and iteration. However, we can generate the recognizable plq languages using special rational expressions consisting of the Boolean operations and restricted versions of multiplication and iteration. From these special rational expressions we can also obtain an MSO logic describing the recognizable plq languages. Moreover, we provide similar results for the class of aperiodic languages in the plq monoid.
Anisotropic stellar solutions in torsion-trace gravity under Karmarkar condition

Published: February 2022

In this paper, we formulate exact anisotropic interior solutions of the Einstein field equations preserving spherically symmetric geometry in the context of [Formula: see text] gravity. To make the system close, we consider a linear function in torsion scalar [Formula: see text] and trace of energy–momentum tensor [Formula: see text], and employ the well-known Karmarkar condition with metric potential of the form [Formula: see text]. We consider standard data of some well-known compact star models (Vela X-1, PSR J1614-2230, Cen X-3 and EXO 1785-248) to estimate the unknown model parameters. We perform physical analysis of the developed model in detail, which includes density profile, pressure profile, anisotropy factor, mass function, gravitational/surface redshift, compactness factor, energy bounds, stability criteria, and the equilibrium condition. The analysis leads us to conclude that solutions are well-behaved and physically viable.

Modeling the Morphological Effects of Catalyst and Ionomer Loading on Porous Carbon Supports of PEMFC

Published: February 2022

We present a model of the cathode catalyst layer morphology before and after loading a porous catalyst support with Pt and ionomer. Support nanopores and catalyst particles within pores and on the support surface are described by size distributions, allowing for qualitative processes during the addition of a material phase to be dependent on the observed pore and particle size. A particular focus is put on the interplay of pore impregnation and blockage due to ionomer loading and the consequences for the Pt/ionomer interface, ionomer film thickness and protonic binding of particles within pores. We used the model to emulate six catalyst/support combinations from literature with different porosity, surface area and pore size distributions of the support as well as varying particle size distributions and ionomer/carbon ratios. Besides providing qualitatively and quantitatively accurate predictions, the model is able to explain why the protonically active catalyst surface area has been reported to not increase monotonically with ionomer addition for some supports, but rather decrease again when the optimum ionomer content is exceeded. The proposed model constitutes a fast translation from manufacturing parameters to catalyst layer morphology which can be incorporated into existing performance and degradation models in a straightforward way.
Critical Role of Structural Water for Enhanced Li+ Insertion Kinetics in Crystalline Tungsten Oxides

Published: February 2022

Electrochemical ion insertion into transition metal oxides forms the foundation of several energy technologies. Transition metal oxides can exhibit sluggish ion transport and/or phase-transformation kinetics during ion insertion that can limit their performance at high rates (<10 min). In this study, we investigate the role of structural water in transition metal oxides during Li+ insertion using staircase potentiostatic electrochemical impedance spectroscopy (SPEIS) and electrochemical quartz crystal microbalance (EQCM) analysis of WO3·H2O and WO3 thin-film electrodes. Overall, the presence of structural water in WO3·H2O improves Li+ insertion kinetics compared to WO3 and leads to a less potential-dependent insertion process. Operando electrogravimetry and 3D Bode impedance analyses of nanostructured films reveal that the presence of structural water promotes charge accommodation without significant co-insertion of solvent, leading to our hypothesis that the electrochemically induced structural transitions of WO3 hinder the electrode response at faster timescales (<10 min). Designing layered materials with confined fluids that exhibit less structural transitions may lead to more versatile ion-insertion hosts for next-generation electrochemical technologies.

With the increase of mine mining intensity, the scope of goaf continues to expand, a large amount of coal remains in goaf, and the spontaneous combustion fire of coal is particularly serious. In addition, the spontaneous combustion of coal under the condition of gas mining is not clear. At once, spontaneous combustion can induce gas explosion, resulting in the waste of manpower and material resources, bringing hidden dangers to the mine safety production. In order to prevent and control the fire caused by spontaneous combustion of left coal under the condition of gas mining, in this paper by means of laboratory test, field measurement, and numerical simulation, the law of spontaneous combustion of residual coal under gas mining is studied. The index gas of coal spontaneous combustion was determined by temperature‐programmed experimental device. Secondly, the distribution of the stope working face, goaf, and O2 is discussed. It is of great significance to study the spontaneous combustion rule of three belts in goaf under acid leaching condition and then to discuss the best position of injection idling opening and put forward targeted precontrol measures, which is of great significance to guarantee the safety of mine production. The results show that CO begins to appear when the temperature rises to 40 °C, and its concentration increases exponentially with the increase of coal temperature, which can reflect the degree of coal oxidation in goaf. Therefore, CO should be selected as the indicator gas in the working face. Under the influence of negative drainage pressure, the dangerous area will be enlarged. The optimal drainage volume of high drainage roadway is 90 m3/min, and the optimal air intake volume of working face is 1400 m3/min. The area 0–34 m away from the working face is scattered zone, 34–135 m away is spontaneous combustion zone, and 135 m away is asphyxiation zone. When the position of the idler is 50 m behind the working face, the reduction of the oxidation zone is the largest.

Sirtuin 6 (SIRT6), a DNA repair-related gene, has undergone an extremely thorough study for its involvement in the development of many different cancers. The objective of our study was to explore the function and mechanism of SIRT6-induced regulation of prostate cancer (PCa). RT-PCR was performed to validate the levels of SIRT6 in PCa cell lines. Cell proliferation, migration, and invasion of cells with SIRT6 knockdown were assessed using CCK-8 assay, colony formation assay, wound-healing assay, and transwell assay. Western blot was applied to assess the related proteins. We found that SIRT6 expression was distinctly upregulated in PCa specimens and cells. Loss-of-functional assays revealed that SIRT6 silence suppressed the proliferation and metastasis of PCa cells. Mechanistic studies revealed that SIRT6 silence inhibited Wnt/β‐catenin signaling and EMT progress. Overall, the study confirmed the upregulation of SIRT6 in patients with PCa and its association with the progression. SIRT6 promoted PCa progression by regulating Wnt/β‐catenin signaling, providing a promising biomarker and treatment approach for preventing PCa.
