Entre la masa del pánico y la articulación populista: conjeturas en torno al lazo social en la época del (pseudo) discurso capitalista; Between the Panic Mass and the Populist Articulation: Conjectures around the Social Bond in the era of the Capitalist (Pseudo) Discourse; Entre la masse de panique et l’articulation populiste: conjectures autour du lien social à l’époque du (pseudo) discours capitaliste Foa Torres, Jorge Gabriel; Reynares, Juan Manuel En este artículo pretendemos reflexionar sobre fenómenos políticos actuales de rasgos autoritarios a partir tanto de algunos desarrollos teóricos que articulan psicoanálisis y lenguajes de la teoría política contemporánea, como de la noción “masa del pánico”. Nuestra conjetura principal es que el actual debilitamiento generalizado de los significantes amo o nombres del padre, que entenderemos aquí a partir del trastocamiento enunciado por Lacan con el matema del discurso del capitalista, nos ubica ante un nuevo escenario donde el sujeto dividido no tiende a inscribirse en el lazo social, sino que, expuesto sin reservas al imperativo superyoico a gozar, se conecta, constituyendo masas del pánico; This paper will delve into current authoritarian political phenomena based on theoretical approaches that articulate psychoanalysis and contemporary political theory languages, and on the idea of “panic mass”. Our main assumption is that the current general weakening of signifiers related to master -or Names-of-the-Father-, approached from the disruption outlined by Lacan through the mathema of Capitalist Discourse, places us on a new scenario where the split subject does not tend to inscribe himself into social bonds, but, exposed without caution to the superego imperative to enjoy, connects and forms panic masses.; Dans cet article nous nous proposons de réfléchir sur des phénomènes politiques actuels, aux traits autoritaires, en nous appuyant, d’un côté, sur quelques développements théoriques articulant la psychanalyse et les langages de la théorie politique contemporaine et, de l’autre côté, sur la notion de « masse de panique ». Notre principale conjecture est que l’affaiblissement généralisé des signifiants maître et les noms du père, entendus ici à partir de la transposition énoncée par Lacan avec le mathème du discours du capitaliste, nous situe face à un nouveau scénario où le sujet divisé ne tend pas à s’inscrire dans le lien social, mais, exposé sans réserve à l’impératif surmoïque de jouir, il se connecte en constituant les masses de panique.

Boxeo, espectáculo y deporte. Hacia la construcción de una institucionalidad pugilística en la Buenos Aires de los años veinte; Boxing, show and sport. Towards the construction of a pugilistic institutional framework in the Buenos Aires of the twenties Fernandez de Ullivarri, Maria El objetivo de este trabajo es analizar las tensiones en la consolidación del boxeo como un deporte-espectáculo en la ciudad de Buenos Aires durante los años veinte. En ese camino nos interesa empezar a desandar esa malla que fue dando forma y sentido a esa práctica: el crecimiento de los clubes de la ciudad, las oportunidades de trabajo que generó para un conjunto amplio de hombres, la institucionalización, la regulación y la construcción de un universo simbólico en torno al pugilismo que incluía formas e imaginarios sociales, así como también la disputa por el gusto de los espectadores y las formas técnica y boxísticamente adecuadas de llevar adelante un combate. Pensar cómo se construyó una práctica física nos puede permitir adentrarnos en las lógicas más internas de un deporte estigmatizado por un lado y valorado por otro, que fue conformando sentidos y masculinidades en el temprano siglo XX.; the main purpose of this paper is to analyze the tensions in the consolidation of boxing as a sport-show in the city of Buenos Aires during the twenties. In this way we are interested in starting to retrace that mesh that was giving form and meaning to the practice of that sport: the development of new clubs in the city, the job opportunities that were generated for a wide group of men, the institutionalization, the regulation and the construction of a symbolic universe around pugilism that included social forms and imaginaries, as well as the dispute for the taste of the spectators and the appropriate ways (in terms of technic and style) to carry out a fight.

Niche partitioning between coexisting gentoo Pygoscelis papua and Magellanic penguins Spheniscus magellanicus at Martillo Island, Argentina Harris, Sabrina; Scioscia, Gabriela; Klemens, Pütz; Thomas, Mattern; Raya Rey, Andrea Nélida Marine top predators living in sympatry tend to use their environment differentially, thereby reducing niche overlap. Magellanic penguins (Spheniscus magellanicus) and gentoo penguins (Pygoscelis papua) coexist at Martillo Is., Argentina. During the 2014, 2015 and 2017 breeding seasons a total of thirty-one Magellanic and eleven gentoo penguins were equipped with GPS-TDR loggers to record foraging trips. Both species dove to similar maximum depths with analogous effort (dives per hour). Magellanics, however, undertook longer trips and travelled further away from the colony (25 h and 43 km vs. 10 h and 20 km on average, respectively). Gentoos on the other hand, performed longer dives, had a higher percentage of “U” shaped dives and spent more time during the bottom phase of the dive. Gentoos foraged exclusively within an area close to the colony and in waters not deeper than 80 m. Magellanics had more variability in their behaviors and were not associated to a specific depth or distance from the colony. The ecological circumstances of both species (targeted prey and surrounding environment) suffice to explain the particular behaviors of both species independently from the presence of the other. Gentoos seem to focus on benthic prey which remains stable in this environment throughout the year, and Magellanics behave more opportunistically searching for pelagic prey during early chick rearing. Competition may not be always shaping coexistence of species of similar trophic positions and behaviors. Particularly, if resources are not limited, both species can behave in ways they find optimal without factoring the coexistence of the other species.

Digging the topology of rock art in northwestern Patagonia Vargas, Fernando Emmanuel; Lanata, Jose Luis; Abramson, Guillermo; Kuperman, Marcelo Nestor; Fiore, Danae We present a study on the rock art of northern Patagonia based on network analysis and communities detection. We unveil a significant aggregation of archaeological sites, linked by common rock art motifs that turn out to be consistent with their geographical distribution and archaeological background of hunter-gatherer stages of regional peopling and land use. This exploratory study will allow us to approach more accurately some social strategies of visual communication entailed by rock art motif distribution, in space and time.

Multiwavelenght study in the region of IRAS sources 16571-4029 and 16575-4023 Baume, Gustavo Luis; Corti, Mariela Alejandra; Borissova, Jura; Ramirez Alegria, S.; Corvera, Andrea V. We studied the stellar populations and their associated interstellar medium structures located in the region of IRAS 16571-4029 and 16575-4023 sources, aiming to evaluate their distance and their main physical parameters. We focused our attention on the embedded cluster DBS 113 and its associated HII region RCW 116B.For the study, optical images were obtained using wide band and narrow band filters (ugri andOIII, OIIIC, H, HC, SII respectively) together with infrared (K band) spectra for several starsin the region of DBS 113. These data were complemented with available information from the literature and photometric multi-band data from several surveys at optical (VPHAS+), infrared (2MASS, VVV, WISE) and radio (SGPS, PMN) spectral ranges. Astrometic and photometric data from GAIA DR2 in the region were also taken into account.All the obtained spectra in DBS 113 region correspond to early type stars (OB). In general, weidentified in this region 2 O-type, í 20 B-type stars, í 25 probable pre-main sequence ones, and 10 candidates to young stellar objects. We also built their stellar energy distributions ranging from 0.3 to 22 m. We found an abnormal behaviour of the reddening law (RV = 4:0) and a corresponding spectrophotometric distance from optical/infrared data consistent with the distance computed from GAIA measurements (d í 2 kpc). This value locates this cluster at the inner side of the Sagittarius-Carina Galactic arm and is different from the traditionally adopted kinematic distance of 1-1.2 kpc, based on hydrogen recombination line at millimeter wavelengths. This difference was explained by the presence of an hydrogen expanding bubble with a central velocity relative the molecular cloud.The new proposed distance value allowed to estimate more precisely the parameter values of the HII region RCW116B and to describe the energetic balance among the emission of most massive stars, the ionization of the region and the heated dust. Regarding the IRAS 16575-4023 source, we found that the brightest star in this region is a foreground object andwe also identified a set of OB stars candidates with high absorption values (AV í 23), located behind the molecular cloud AGAL345.336+01.021.

Stable isotopes in hair reveal dietary protein sources with links to socioeconomic status and health Ehleringer, James R.; Covarrubias Avalos, Stephannie; Tipple, Brett J.; Valenzuela, Luciano Oscar; Cerling, Thure E. Carbon and nitrogen isotope ratios in hair sampled from 65 communities across the central and intermountain regions of the United States and more intensively throughout 29 ZIP codes in the Salt Lake Valley, Utah, revealed a dietary divergence related to socioeconomic status as measured by cost of living, household income, and adjusted gross income. Corn-fed, animal-derived proteins were more common in the diets of lower socioeconomic status populations than were plant-derived proteins, with individual estimates of animal-derived protein diets as high as 75%; United States towns and cities averaged 57%. Similar patterns were seen across the socioeconomic status spectrum in the Salt Lake Valley. It is likely that corn-fed animal proteins were associated with concentrated animal-feeding operations, a common practice for industrial animal production in the United States today. Given recent studies highlighting the negative impacts of animal-derived proteins in our diets, hair carbon isotope ratios could provide an approach for scaling assessments of animal-sourced foods and health risks in communities across the United States.

Patrimonio sonoro y digitalización: Memorias radiofónicas e imaginarios sociales regionales sobre LU10 Radio Azul Boggi, Silvia Marta; Silva, Ana Cecilia; Arabito, Jorge Este artículo expone los principales resultados obtenidos a partir del desarrollo de diversas acciones y estrategias destinadas a la recuperación, puesta en valor y disponibilidad pública del patrimonio sonoro y gráfico de LU10 Radio Azul, emisora de AM ubicada en la ciudad bonaerense homónima que inició su transmisión en la década de 1950 y continúa en el aire. Desde el año 2016 un equipo integrado por docentes investigadorxs y estudiantes de la Facultad de Ciencias Sociales de la Universidad Nacional del Centro de la Provincia de Buenos Aires, en articulación con trabajadores de la radio, nos hemos ocupado del acondicionamiento, catalogación, digitalización y difusión de los archivos sonoros de esa radiodifusora, labor que en la última etapa se amplió a la documentación gráfica almacenada en su edificio. El trabajo sobre el material de archivo, así como la utilización del mismo en nuevas producciones radiofónicas, permitió abrir líneas de indagación acerca de los modos en que la presencia de la radio se ha entramado con la dinámica sociocultural de la localidad y la región.

Recursos para una historia de las culturas musicales: la Revista de la Asociación Wagneriana de Buenos Aires (1914-1926); Recursos para uma história das culturas musicais: a Revista de la Asociación Wagneriana de Buenos Aires (1914-1926); Resources for a History of Musical Cultures: The Revista de la Asociación Wagneriana de Buenos Aires (1914-1926) Irurzun, Maria Josefina El objetivo general del presente trabajo es complejizar los abordajes tradicionales de las revistas de música para concebirlas como dispositivos y prácticas de acción social que caracterizan a las culturas musicales, así como interpelan diversas esferas de la opinión pública. Para ello, se analiza el caso de la Revista de la Asociación Wagneriana de Buenos Aires (publicada por la Asociación homónima), a partir de la periodización de los momentos vitales o editoriales de la misma, atendiendo a la pluralidad de contextos y los aspectos relacionados con ellos, su forma de organización colectiva como espacio de enunciación, sus modos de ser, estilo, recursos, etc. Se argumenta que, si bien la dependencia de la publicación respecto a la entidad condicionó su forma y contenido, operó también como una institución en sí misma (“una tribuna de arte y cultura”). Por último, se señalan las múltiples posibilidades de indagación de las revistas de música (con frecuencia concebidas como “manifestaciones” de procesos que ocurren por fuera de ellas), la dinámica de sus cambios e intervenciones y las distintas significaciones –otorgadas a través del tiempo–, que las convierten también en revistas culturales.; O objetivo geral do presente trabalho é complexificar as abordagens tradicionais das revistas de música para concebê-las como dispositivos e práticas de ação social que caracterizam as culturas musicais, assim como interpelam diversas esferas de opinião pública. Para tal, analisa-se o caso da Revista de la Asociación Wagneriana de Buenos Aires (publicada pela associação homónima), a partir da periodização dos momentos vitais ou editoriais da mesma, atendendo à pluralidade de contextos e aspectos relacionados com eles, sua forma de organização coletiva como espaço de enunciação, seus modos de ser, estilo, recursos, etc. Argumenta-se que, embora a dependência da revista em relação à entidade condicionou a sua forma e conteúdo, operou também como uma instituição em si mesma (“uma tribuna de arte e cultura”). Por último, assinala-se a dificuldade inerente à indagação das revistas de música (com frequência concebidas como “manifestações” de processos que ocorrem por fora delas), a dinâmica de suas mudanças e intervenções e as diferentes significações –outorgadas através do tempo– que as convertem também em revistas culturais.; The main objective of this paper is to rethink traditional approaches by music magazines and conceive of them as social action devices and practices that gave distinctive characteristics to musical cultures and took place in different spheres of public opinion. The analysis is based on the Revista de la Asociación Wagneriana de Buenos Aires (published by the association of the same name), starting from the periodization of its vital or editorial phases, taking into account the plurality of contexts and the aspects related to them, their collective organization as a space of enunciation, their style, resources, etc. It was found that, while the institutional dependency of the publication conditioned its form and content, it also operated as an entity in itself (“a forum for art and culture”). Finally, attention is drawn to the multiple possibilities of researching music journals (often conceived as “manifestations” of processes occurring outside them), the dynamics of their changes and interventions, and the different meanings granted through time-, that turn them into cultural magazines.

Linear segmented polyurethanes. III. Mathematical model for a two-steps polymerization Polo, Mara Lis; Spontón, Marisa Elisabet; Huespe, Alfredo Edmundo; Estenoz, Diana Alejandra; Meira, Gregorio Raul In the first article of this sequel (J. Appl. Polym. Sci., 2018, 135, 45747), an experimental and theoretical investigation was developed on the two-steps synthesis of linear segmented thermoplastic polyurethanes. The reactions were carried out at 60°C, with methylene diphenyl diisocyanate (MDI), two poly(tetramethylene oxide) macrodiols, and 1,4-butanediol (BD) as chain extender. In our second article (J. Appl. Polym. Sci., 2019, 136, 46946), a mathematical model for the prepolymerization was developed, that involved integrating a differential equation for each generated polymer species. The present article extends such model, and predicts the molecular structure along the finishing stage. In each stage, the new model first solves the molar balances at polymer topologies level (i.e.,: Disregarding the molar mass distribution [MMD] of the reacted macrodiol chains), and then calculates the MMD of the evolving polymer and its main subsets through an algebraic convolution procedure. The model reproduces the prepolymerization predictions of our previous article, but is three orders of magnitude faster. In the finishing stage, up to 156,000 polymer topologies and 4.53 × 108 polymer species were calculated; and the rate constant was readjusted to (k2 = 0.00129 L mol−1 s−1), in order to fit the measured MMDs.

El "siempreverde" (Ligustrum lucidum) ¿altera la composición de las comunidades de hongos micorrícicos arbusculares en el chaco serrano? Borda, Valentina; Cofré, María Noelia; Longo, Maria Silvana; Grilli, Gabriel; Urcelay, Roberto Carlos Las invasiones biológicas representan una gran amenaza para la biodiversidad y la integridad de los ecosistemas dado que alteran las comunidades bióticas. Entre las comunidades bióticas del suelo se destacan los hongos micorrícicos arbusculares (HMA), que establecen asociaciones simbióticas con la mayoría de las plantas terrestres. Las especies de HMA no responden del mismo modo a los cambios ambientales, por lo que se propuso la existencia de grupos de especies de HMA con estrategias ecológicas compartidas (ruderales, competidoras y estrés tolerantes). Las plantas invasoras son capaces de alterar las comunidades de HMA para su propio beneficio. Este podría ser el caso del ?siempreverde? (Ligustrum lucidum), un árbol asiático que invade numerosos sectores de la Argentina y forma, en algunas zonas, bosques monoespecíficos densos. En este estudio se compararon las comunidades de esporas de HMA entre bosques monoespecíficos de siempreverde y bosques chaqueños serranos nativos. Se seleccionaron 6 áreas con ambos tipos de bosque. De cada área se tomaron muestras de suelo, a las que se les midieron características físico-químicas y se les extrajeron las esporas de HMA. De acuerdo con lo esperado, la composición de las comunidades de esporas de estos bosques monoespecíficos fue diferente a la presente en suelos de bosques nativos. La riqueza de morfoespecies de esporas de HMA no mostró diferencias entre ambos tipos de bosque, pero la abundancia total fue mayor en los suelos de bosque de siempreverde, que presentan un mayor número de esporas de especies ruderales. Este estudio provee evidencia que sugiere que la expansión del siempreverde altera las comunidades de esporas de HMA y algunas propiedades químicas del suelo. Estos cambios posiblemente sean parte del mecanismo que promueve la formación de bosques monoespecíficos.

Riqueza potencial de murciélagos en el sur de las Yungas: aportes para la conservación de especies; Bat potential species richness in the southern Yungas: contribution to the conservationof species Castilla, María Cecilia; Cuyckens, Griet An Erica; Zucarelli, Verónica; Díaz, María Mónica Dentro de las Yungas en Argentina, la porción austral presenta ecotonos con eco-regionesmás áridas como el Chaco, la Puna y el Monte de Sierras y Bolsones. Posee alta diversidad de murciélagos, pero la riqueza disminuye drásticamente encima de los 23°S a 24°S. Este trabajo deriva de un estudio acerca de una colonia de Tadarida brasiliensis ubicada en el Dique Escaba (Tucumán), reconocida como Sitio de Importancia para la Conservación de los Murciélagos (SICOM). El objetivo fue evaluar, desde los factores bioclimáticos, la distribución y riqueza de especies de murciélagos en la porción austral de las Yungas, para contextualizar la importancia de ensambles locales y la utilización de la riqueza potencial como insumo para la designación de Áreas de Importancia para la Conservación de los Murciélagos (AICOMs). A partir de registros de presencia se estimaron distribuciones potenciales mediante el software MaxEnt, para lo quese seleccionaron previamente las variables mediante un Análisis de Componente Principales (pendiente, rango anual de la temperatura y temperatura media del trimestre más frío). El mapa de riqueza de especies se obtuvo sumando los modelos con un buen rendimiento y puntos de presencia de especies no modeladas. Se registraron 27 especies de murciélagos predominantemente insectívoras. La riqueza potencial de especies aumentó asociada a la distribución las Yungas, los cordones montañosos y los ecotonos con las zonas áridas.Los modelos de distribución son buenas herramientas para identificar AICOMs en función de su riqueza potencial, como los alrededores del Dique de Escaba (Tucumán)-Cuesta la Higuerilla (Catamarca) y la cuesta del Totoral y Dique Sumampa (Catamarca), donde se han realizado relevamientos de murciélagos y por eso se han declarado como tales.; In Argentina, the Yungas austral portion presents ecotones with arid eco-regions such as Chaco,Puna, and Monte of Mountains and Isolated Valley. It has a high diversity of bats, but the richness decreasesdrastically above 23°S and 24°S. This research derives from a study on a colony ofTadarida brasiliensislocatedin the Escaba Dam (Tucumán), and recognized as an Important Site for Bat Conservation (SICOM in Spanish).The objective was to assess, from bioclimatic factors, the distribution and richness of bat species in thesouthern portion of the Yungas, to contextualize the importance of local assemblages, and the use of potentialrichness as an input for the designation of Important Areas for Bat Conservation (AICOMs in Spanish). Fromthe presence records, potential distributions were estimated using the MaxEnt software, for which the variableswere previously selected through a Principal Component Analysis (slope, annual temperature range, andaverage temperature of the coldest quarter). The species richness map was obtained by adding the signi cantmodels and points of presence of non-modeled species. 27 species of bats predominantly insectivorous wererecorded. Potential species richness increased within the Yungas, across mountain ranges and at the ecotoneswith arid zones. Distribution models are appropriate tools to detect AICOMs based on their potential richness,such as the surroundings of the Escaba Dam (Tucumán) - Cuesta Higuerilla (Catamarca), and the Totoralslope and Sumampa Dam (Catamarca), where bat surveys have been performed and thereafter, they have beendeclared as such.

Regional development gaps in Argentina: A multidimensional approach to identify the location of policy priorities Niembro, Andrés Alberto; Sarmiento, Jesica Isabel Spatial inequalities within Latin American countries have historically attracted the interest ofacademics, policy-makers, and international agencies. This article aims to provide amultidimensional diagnosis of provincial development gaps in Argentina, in order to identifythe location of policy priorities. Therefore, we built a large database, which covers sevendevelopment dimensions, and applied multivariate analysis techniques to overcome someanalytical limitations of previous studies. Results show the stability of provincial developmentgaps between 2003 and 2013 and some heterogeneity within geographic regions. Instead,cluster analysis offers a better classification of Argentine provinces according to theirdevelopment gaps, which can help the government to prioritize the places wheredevelopment policies are strategic.

Designing a wider superelastic window la Roca, Paulo Matías; Sade Lichtmann, Marcos Leonel Conventional metal alloys can only recover their original shape if subjected to very small elastic deformations. Superelastic alloys (also named pseudoelastic alloys) can recover their shape after deformations as great as 20% (1) just by unloading the force on the material. They are part of the larger group of shape-memory alloys but do not require a temperature change for recovery, and they have found applications in areas including robotics, structural engineering of buildings, and aerospace engineering (2, 3). A superelastic alloy usually exhibits this property only over a well-determined and often small temperature range normally called a “superelastic window.” On page 855 of this issue, Xia et al. (4) describe superelastic “invar” alloys with functional properties that are independent of temperature over the largest superelastic window reported, from 10 to 473 K.

Advantages of rainfall partitioning by the global invader Ligustrum lucidum over the dominant native Lithraea molleoides in a dry forest Whitworth Hulse, Juan Ignacio; Magliano, Patricio Nicolás; Zeballos, Sebastián Rodolfo; Gurvich, Diego Ezequiel; Spalazzi, María Florencia; Kowaljow, Esteban Vegetation canopy plays a key role in the local water balance by partitioning rainfall into interception, throughfall and stemflow in dry forests. Many invasive plants have the capacity to replace native species and alter the net amount and spatial distribution of rainfall reaching the soil. In this paper, we aimed to compare the rainfall partitioning for the invader Ligustrum lucidum and the dominant native Lithraea molleoides, to evaluate the influence of morphological characteristics on stemflow generation in both species, and to explore spatio-temporal patterns of throughfall at stand scale. Stemflow percentage for L. lucidum was hugely higher than for L. molleoides (18 and 1%, respectively), which overcompensated its lower throughfall percentage (58.1 and 68.6%, respectively). Interception losses were lower for L. lucidum than for L. molleoides (23.2 and 30.6%, respectively). The minimum rainfall amount needed to generate throughfall and stemflow was 1.8 and 0.5 mm for L. lucidum, while 2.2 and 7.2 mm for L. molleoides. The differences in morphological characteristics between species mainly explained the stemflow generation. The increment on tree basal area, projected canopy area, and number of branches favored stemflow in L. lucidum, but not in L. molleoides. The throughfall spatial patterns showed that the dripping from different canopy densities was homogenous in L. lucidum stands, whereas throughfall increase towards more opened-canopies in L. molleoides stands. Lateral inflows were registered from small-scale crown sections at both forest stands, but less frequent in L. lucidum stands. The time stability of throughfall pattern differed between forest stands. Based on our results, relatively higher stemflow and lower interception losses for L. lucidum than for L. Molleoides may represent a competitive advantage in terms of plant invasion in water-limited ecosystems. These findings highlight the need for further inquiries determining the underlying role of rainfall partitioning in the invasion process of woody species.

Reflexiones sobre Responsabilidad Internacional de un Estado por la propagación del COVID-19 Castillo Argañarás, Luis Fernando Al surgir la enfermedad de COVID-19, el Estado donde se originó, no cumplió con las obligaciones del Reglamento Sanitario Internacional (2005) de la Organización Mundial de la Salud. Frente a este hecho ¿Surge responsabilidad internacional conforme la Resolución 56/83 de Asamblea General de la ONU del año 2001?.

Una App para conocer la calidad de vida de cualquier lugar de la República Argentina Velázquez, Guillermo Ángel; Zunino Suarez, Alejandro Octavio; Mikkelsen, Claudia Andrea; Linares, Santiago; Celemin, Juan Pablo; la Macchia, Maria Lorena; Manzano, Fernando; Tisnés, Adela Durante las últimas décadas, las innovaciones tecnológicas y transformaciones sociales están promoviendo un cambio de paradigma en la divulgación científica, en donde, la interactividad, la colaboración, el acceso remoto a la información y la liberación progresiva de los datos son sus elementos más representativos. Dentro de este proceso evolutivo, el campo de la Información Geográfica no ha quedado exceptuado, sino que por el contrario, ha sido una de las áreas más impactadas por el aumento de la capacidad computacional, dando origen a un número creciente de nuevas bases de datos, accesibilidad digital a las mismas y algoritmos de consulta y transformación de dicha información geográfica que poco a poco van reemplazando a aquella almacenada en los tradicionales mapas analógicos…

Experience and results with a telehealth treatment program in patients with cognitive disorders during the COVID-19 pandemic Dorman, Guido; Alvarez Dengra, Agustín; Fiorini, Adriana; Failla, Belén; Vallejos, Florencia; Pontello, Noelia; Roca, María; Bustin, Julian The COVID‐19 pandemic has led to the adoption of social quarantine measures in numerous countries. In this context, both COVID‐19 and quarantine can have a substantial impact in the mental health of affected populations. Health care services have had to adapt themselves to this new reality.

The impact of an early strict nationwide lockdown on the pattern of consultation for neurological diseases Calandri, I.L.; Hawkes, Maximiliano Alberto; Marrodán, María Dolores; Ameriso, Sebastian Francisco; Correale, Jorge; Allegri, Ricardo Francisco A massive disruption of healthcare systems, a profound economic depressionand a distressing social situation [1]. Most countries enteredinto a lockdown in an attempt to slow the spread of the virus once theywere already suffering a serious hit. Based on the experience observed in Europe, Argentina closed its borders on March 15thonly one week afterthe firstperson died of COVID-19, and implemented an early nationwidelockdown limiting the circulation of 90% of its population, on March20th, with 128 cases and 3 deaths of COVID-19 [2-3]. Most health careresources were reassigned in anticipation of a catastrophic situation. Themassive communication media and the medical community warned thepopulation about the necessity of avoiding ?non-urgent? consults to theemergency rooms to avoid the overload of the system.To evaluate the impact of the national lockdown policy during theCOVID-19 pandemic,we compared the pattern of consultation to a tertiaryneurological center.Patients who attended to our ED have primaryneurological complaints or presented chronic neurological conditionswith varied medical problems. The period evaluated was the quarantineperiod (March 20st to April 26th 2020) with the same timeframeof 2019.Descriptive summaries are presented as mean or median (standarddeviation, SD) for continuous variables and proportions for categoricalvariables. The t-test or Mann-Whitney test were used to comparequantitative variables as appropriate. Pearson Chi-Square test or Fisher´sexact test were used to comparefrequencies of categorical variables asappropriate.A p-value < 0.05 was considered significant. The statisticalanalysis was performed with R-3.6.1, and the tydiverse, ggpubr, andggplot2 packages. This research has been approved by the Institutional Ethics Committee.

Soybean yield, protein content and oil quality in response to interaction of arbuscular mycorrhizal fungi and native microbial populations from mono and rotation-cropped soils Marro, Nicolás Alejandro; Cofré, María Noelia; Grilli, Gabriel; Alvarez, Carolina; Labuckas, Diana Ondina; Maestri, Damián; Urcelay, Roberto Carlos Two main soil management practices are generally used for soybean production: monoculture (MC) and crop rotation (CR). These strategies have different impacts on soil microbial communities. Among them, arbuscular mycorrhizal fungi (AMF) are well known to provide access to nutrients in a majority of cultivated plants. AMF communities have been shown to be more diverse in CR than in MC. Because AMF species differ in their effects on nutrition and development of plants, it could be expected that soil biota from different soil management practices affect soybean yield and quality. Therefore the objective of this study was to examine the combined effects of soil microbial communities and soil management practices (MC and CR) on yield, protein content, and oil quality of soybean grown under greenhouse conditions. The effects of three soil treatments, namely: sterile (S); microorganisms without AMF (MO); and microorganisms with AMF (AMF) were evaluated. These treatments were applied to soils from two crop management practices (CR and MC). Sterile soil promoted lower numbers of pods and seed weight per plant in MC but not in CR. AMF showed increased seed protein content (12?14%) whereas MO presented increased oil concentration (20?27%) (mainly within CR). Soybean grown with AMF from CR soil showed significantly higher amounts of oleic acid (21?25%), and lower linoleic acid (9%) when compared with other treatments. Findings from this study suggest that soybean yield and quality are affected by crop management practices and soil biota composition. Further, these parameters should be considered at the time of selecting agricultural strategies.
