High β-Glucans Oats for Healthy Wheat Breads: Physicochemical Properties of Dough and Breads Astiz, Valentina; Guardianelli, Luciano Martin; Salinas, Maria Victoria; Brites, Carla; Puppo, Maria Cecilia Bread is a highly consumed food whose nutritional value can be improved by adding an oat flour (Avena sativa L.-variety Bonaerense INTA Calen-Argentina) to a high-industrial quality wheat flour (Triticum aestivum L.). This cultivar of oat contains high amounts of β-glucans, which act as a prebiotic fiber. Wheat flour was complemented with different amounts of oat flour (5, 15, and 25%). A contribution of hydrophilic components from oat flour was evident in the oat–wheat mixtures. At the same time, the high content of total dietary fiber led to changes in the rheological properties of the dough. Mixtures with a higher proportion of oats showed an increase in alveographic tenacity (stiffer dough), higher stability, and a lower softening degree in farinographic assays. The dough showed significant increases in hardness and gumminess, without significant changes in cohesiveness, i.e., no disruption to the gluten network was observed. Relaxation tests showed that the blends with a higher oat content yielded 10 times higher stress values compared to wheat dough. Analysis of the oat–wheat breads showed improvements in nutritional parameters, with slight decreases in the volume and crust color. The crumb showed significant increases in firmness and chewing strength as the amount of oats added increased. Nutritional parameters showed that lipids, dietary fiber, and β-glucans were significantly increased by the addition of oats. Sensory analysis achieved high response rates with good-to-very good ratings on the hedonic scale set. Thus, the addition of oats did not generate rejection by the consumer and could be accepted by them. Breads with wheat and oats showed nutritional improvements with respect to wheat bread, since they have higher dietary fiber content, especially in β-glucans, so they could be considered functional breads.

Conflictos en las traducciones del concepto bíblico ‘diablo’ en lengua hebrea al griego y del español al wichí: Una construcción conceptual del Mal; Conflicts in the translations of the biblical concept ‘devil’ from Hebrew into Greek and from Spanish into Wichí: A conceptual construction of Evil; Conflitos nas traduções do conceito bíblico de “diabo” do hebraico para o grego e do espanhol para o wichí: Uma construção conceitual do mal Figueroa León, Carolina Angélica El concepto "diablo" tanto en lengua griega como wichí tenía otro sentido y función previo a la cristianización. Esto se evidencia mediante un análisis filológico, antropológico y etnohistórico de las traducciones de "diablo" desde su origen en hebreo al griego y del término en español al wichí. Estudio que se inserta dentro de una investigación mayor que contempla el análisis de un conjunto de conceptos cristianos y trabajo etnográfico en comunidades wichí del Gran Chaco. A partir de esta investigación se detecta que en el caso de la lengua griega la inserción del sentido cristiano en la palabra "διάβολος" fue completa. Aunque, ciertamente esto no se hizo sin dejar residuos, pues junto a "diablo" persisten en el cristianismo todos los demás nombres hebreos junto a otros préstamos griegos. Mientras que en el wichí el término "Ahättaj" conserva aún elementos de la cosmovisión indígena, aunque se han permeado con la doctrina cristiana.; The concept ‘devil’ in both Greek and Wichí had another meaning and function prior to Christianization. This is evidenced by means of a philological, anthropological and ethnohistorical analysis of the translations of ‘devil’ from its Hebrew origin into Greek and from the Spanish term into Wichí. This study is part of a larger research that includes the analysis of a set of Christian concepts and ethnographic work in Wichí communities of the Gran Chaco. From this research it is detected that in the case of the Greek language the insertion of the Christian sense in the word “διάβολος” was complete. Although, this was certainly not done without leaving residues, for together with ‘devil’ persist in Christianity all the Hebrew de-more names together with other Greek borrowings. While in the Wichí the term “Ahättaj” still retains elements of the indigenous worldview, although they have been permeated with Christian doctrine.; O conceito ‘diabo’ tanto em grego quanto em wichí tinha um significado e função diferentes antes da cristianização. Isto é evidenciado por meio de uma análise filológica, antropológica e etno-histórica das traduções do ‘diabo’ de sua origem hebraica para o grego e do termo espanhol para o wichí. Este estudo é parte de um projeto de pesquisa maior que inclui a análise de um conjunto de conceitos cristãos e trabalho etnográfico nas comunidades Wichí no Gran Chaco. Esta pesquisa mostra que, no caso da língua grega, a inserção do significado cristão na palavra “διάβολος” foi completa. Embora, isto certamente não foi feito sem deixar resíduos, pois junto com o ‘diabo’ todos os nomes hebreus de-mais persistem no cristianismo junto com outros empréstimos gregos. Enquanto no Wichí o termo “Ahättaj” ainda retém elementos da visão de mundo indígena, embora tenham sido permeados pela doutrina cristã.

Evolución estructural de la fosa del Toro: Influencia de estructuras precretácicas en la faja plegada y corrida andina, Cordillera Oriental argentina; Structural evolution of the Quebrada del Toro Basin: Influence of pre-cretaceous structures on the Andean fold-and-thrust belt in the Argentinian Eastern Cordillera Villagrán, Carla Agustina; Seggiaro, Raul Eudocio; Filipovich, Ruben Eduardo; Apaza, Facundo Domingo; Barrabino, Emilio; Celedon, Ruth Melina La superposición de los eventos tectónicos registrados en la Cordillera Oriental argentina condicionó el estilo estructural actual. En la quebrada del Toro (provincia de Salta), coincidente con el tramo central del lineamiento Calama-Olacapato-Toro (COT), se reconocen estructuras paleozoicas que habrían ejercido un significativo control estructural durante la tectónica andina. En esta contribución se presentan nuevos datos estructurales, estratigráficos y sedimentológicos de la quebrada del Toro que permitieron un análisis integral mediante la generación de secciones geológicas balanceadas, restituciones de la deformación y modelados cinemáticos 2D (forward modeling). Se identificaron al menos dos eventos de deformación. El primero de ellos, desarrollado durante la fase extensional Tumbaya en el Tremadociano tardío, se expresa mediante dos fallas (de La Cruz y Pascha) normales sinsedimentarias, mientras que el segundo, de carácter compresivo, se habría iniciado durante el Eoceno medio, con la generación de corrimientos someros (e.g. corrimiento Toro) y pliegues de gran escala, luego, transportados por fallas inversas de alto ángulo (fallas Gólgota y Lampazar) con despegues profundos. Las relaciones estructurales de ambos eventos de deformación constituyen claras evidencias del control que habrían ejercido las fallas paleozoicas en la localización del corrimiento Toro durante la tectónica andina.; The superimposition of the tectonic events recorded in the Argentinian Eastern Cordillera conditioned the current structural style. In the Quebrada del Toro Basin (Salta province), coinciding with the central section of the Calama-Olacapato-Toro lineament (COT), pre-cretaceous structures are recognized that would have favored the development of inverse structures during Andean tectonics. We present new structural, stratigraphic and sedimentological data which allowed an integral analysis through the generation of balanced geological sections, deformation restorations and 2D forward modeling. At least two deformation events were identified: the first, during the upper Tremadocian, corresponds to the Tumbaya extensional phase expressed through two NNW-SSE striking and ENE dipping normal synsedimentary faults (de la Cruz and Pascha). The second deformation event, of compressive nature, would have begun during the middle Eocene, with the generation of large-scale folds related to relatively shallow Gólgota thrust and their subsequent transport by two high angle reverse faults (Gólgota and Lampazar) with deeper detachment. In this sense, Paleozoic structures controlled the location and western vergence of the Gólgota thrust in the study area, a caracteristic that reinforces the hypothesis about the preponderant influence of Ordovician normal faults on western vergence thrusts.

Collisions between CO, CO 2 , H 2 O and Ar ice nanoparticles compared by molecular dynamics simulation Nietiadi, Maureen L.; Rosandi, Yudi; Bringa, Eduardo Marcial; Urbassek, Herbert M. Molecular dynamics simulations are used to study collisions between amorphous ice nanoparticles consisting of CO, CO2, Ar and H2O. The collisions are always sticking for the nanoparticle size (radius of 20 nm) considered. At higher collision velocities, the merged clusters show strong plastic deformation and material mixing in the collision zone. Collision-induced heating influences the collision outcome. Partial melting of the merged cluster in the collision zone contributes to energy dissipation and deformation. Considerable differences exist—even at comparable collision conditions—between the ices studied here. The number of ejecta emitted during the collision follows the trend in triple-point temperatures and increases exponentially with the NP temperature.

LED visible light assisted photochemical oxidation of HCHs in aqueous phases polluted with DNAPL Conte, Leandro Oscar; Cotillas, Salvador; Sánchez Yepes, Andrés; Lorenzo, David; Santos, Aurora This work focuses on removing hexachlorocyclohexanes (HCHs) found in groundwater polluted with dense non-aqueous phase liquids (DNAPLs) by photo-oxidation with hydrogen peroxide or persulfate using LED visible light and ferrioxalate as the catalyst. Single oxidation tests were also performed to evaluate the contribution of LED-vis light on HCHs removal. Results show that it is possible to attain the degradation of HCHs up to 85% in 420 min with persulfate, whereas percentages lower than 40% are obtained when using hydrogen peroxide. Using both oxidants in the presence of ferrioxalate and LED visible light promotes the generation of hydroxyl and sulfate radicals under circumneutral pH values, which are the main responsible species for HCHs removal. Specifically, an oxidant conversion higher than 50% was achieved during the photochemical treatment with both oxidants, whereas conversions below 20% were obtained in the absence of LED visible light irradiation. On the other hand, DNAPL produced as liquid residuum of lindane production contains other chlorinated organic compounds (COCs), which are susceptible to being oxidized by hydroxyl and sulfate radicals, generating competitive oxidation reactions. The final conversion of chlorbenzenes reaches values close to 100% and HCHs are only effectively removed when persulfate is used as the oxidant. This better performance indicates that the photo-oxidation of DNAPL polluted groundwater with LED-vis light should be carried out with persulfate to ensure the removal of more dangerous COCs. This confirms the excellent ability of sulfate radicals for C-Cl bond breakdown.

Black grain eumycetoma due to Diaporthe ueckerae: Taxonomical update of previous agents of infections due to Diaporthe spp. Cabeza, Matías Sebastián; Gómez, Abel; Sasoni, Natalia; Gamarra, Soledad; Garcia Effron, Guillermo A black-grain eumycetoma due to Diaporthe uekerae in a kidney transplant recipient is presented. The isolate was identified by using the newly available NCBI's curated database (rRNA_typestrains/ITS_RefSeq_Fungi) and the NCBI's GenBank + EMBL + DDBI + PDB + RefSeq database. The isolate's antifungal susceptibility was evaluated. The studied isolate showed low MIC values to the eight tested antifungals. Using this updated database, the identities of previous agents of Diaporthe spp. infections were revised.

Deliberative processes in decision making informed by health technology assessment in Latin America Alcaraz, Andrea; Pichón-riviere, Andres; García Martí, Sebastián; Alfie, Verónica; Augustovski, Federico Ariel; Castro, Héctor Objective The objective of Health Technology Assessment International's 6th Latin America Policy Form, held in 2021, was to explore the implementation of deliberative processes in the framework of health technology assessment (HTA) and how agencies in the region could involve stakeholders in this process. Methods This paper is based on a preparatory survey, a background document, and the deliberative work of participants at the virtual Forum conducted in 2021. There were ninety-one participants in the open session and fifty-two in the closed sessions, representing twelve countries and diverse areas of the health sector. Results While there are mechanisms in most countries in Latin America to consider stakeholder involvement to some degree, it remains reduced or limited to a consultative role, making true participative involvement rare. There are significant barriers and structural and contextual limitations that have impeded or slowed progress toward deliberative processes. Relatively low levels of institutionalization and knowledge about HTA, as well as the lack of trust among stakeholders are important challenges. This situation has impacted health systems by diminishing the legitimacy of decisions and the very structures and processes of HTA. Conclusion The Forum's broad group of participants identified barriers, facilitators, and recommendations to improve the use of deliberative processes in Latin America to foster improved fairness and reasonableness in HTA and decision making.

Reflexiones en torno a las experiencias escolares de jóvenes migrantes: Entre la desigualdad y el ejercicio de derechos; Reflections on scholar experiences of young migrants: Between the inequality and the exercise of rights González, Mariana Alejandra En Argentina la educación secundaria es obligatoria desde el 2006; asimismo, es un derecho para la población migrante que debe ser garantizado en condiciones de igualdad respecto de los jóvenes nativos (Ley de Educación Nacional y Ley Nacional de Migraciones). Sin embargo, los datos de tasas de abandono y egreso efectivo muestran que este derecho se encuentra vulnerado. Frente a la complejidad de esta situación, el presente ensayo esboza algunos elementos que podrían estar condicionándola. En primer lugar, se presentan características propias del formato escolar, desde un recorrido que parte de su origen hasta la actualidad. En segundo lugar, se refiere el modo en que los jóvenes migrantes se insertan en dicho sistema, explicitando su asimilación y las prácticas de etiquetamiento a partir de un carácter étnico. Por otro lado, se visibilizan las tensiones entre tales trayectorias y las vivencias familiares, al reconocer la importancia del avance en la carrera escolar como una inversión del grupo familiar. Desde tales factores, se introduce a la Sociología de la Experiencia como una aproximación teórica-epistemológica para el abordaje de una situación compleja como es la educación de jóvenes migrantes. El ensayo concluye recuperando las argumentaciones previas, a la vez que recupera planteos en torno a la desigualdad relacional, con la finalidad de posicionar la potencia de la escuela, para mitigar vivencias de inequidad.; In Argentina secondary school is mandatory since 2006, moreover it is a right for migrants, which must be warrantied in equal conditions, in comparisson with native youth (Education National Law and Migration National Law). However, data shows dropout rates and efective graduation that reveal the breach of that right. From this situation, the present essay outline some elements that may be conditioning it. First, it is showed some typical characteristics of the educational format, since the beggining until present time. Second, it refers to the way young migrants students are integrated in that system, focusing in the asimilation and the labeling practices from an etnic character. From other point of view it is showed the tensions between those trajectories and the familiar experiences, so it becomes very important the progress in educationas an invest of all the family group. From those elements, it is introduced the Sociology of Experience as an epistemological and theorical approach of this kind of complexed situations, as the education of migrants is. This essay finishes taking back some previous developments, as it also brings back some ideas related to the relational inequality as a way to show the power of school, to mitigate experiences of inequality.

Una herramienta para la restauración de ambientes ribereños degradados de la cuenca Matanza - Riachuelo: Lotus Tenuis Waldst. & Kit. En simbiosis con hongos micorrícicos arbusculares; A tool for the restoration of degraded riverside environments of the Matanza-Riachuelo basin: Lotus Tenuis Waldst. & Kit. In symbiosis with arbuscular mycorrhizal fungi García, Ileana Vanesa; Weigandt, Cristian Fernando; Fabrizio de Iorio, Alicia Rosa; de Cabo, Laura Isabel La fitorremediación implica la destrucción, inactivación o estabilización de contaminantes (e.g. metales pesados) por parte de las plantas –y microorganismos asociados a sus raíces–, y permite mejorar la calidad de los suelos. Se estudió la capacidad de Lotus tenuis Waldst. & Kit. para absorber metales y asociarse con hongos micorrícicos arbusculares (HMA) y rizobios nativos de suelos de la Cuenca Matanza-Riachuelo. Plantas de L. tenuis fueron cultivadas en invernáculo en suelos ribereños de Gral. Las Heras (S1), Marcos Paz (S2) y Avellaneda (S3) durante 50 días. La fertilidad, los metales totales (ME-T) y la densidad de esporas (DE) edáficos se cuantificaron presiembra y a cosecha de las plantas. Se midió biomasa del vástago y radical, pigmentos fotosintéticos, Cu, Cr, y Zn en vástago y raíz, colonización HMA y nodulación radical. Se calcularon factores de translocación (FT) y bioconcentración (FBC) de metales. El fósforo disponible aumentó de S1 a S3 y disminuyó en S2 y S3 luego del cultivo. ME-T y ME-DTPA fueron mayores en S3 que en S1 y S2; no difirieron al finalizar el cultivo. La DE disminuyó desde S1 a S3. La biomasa aumentó y los pigmentos disminuyeron de S1 a S3. La colonización HMA no difirió significativamente entre sitios. El número de nódulos g-1 peso fresco radical fue 9,7 en S1, 67,6 en S2 y 41,8 en S3. En general, la concentración de metales fue mayor en raíz y el FBC disminuyó de S1 a S3. Ante contaminación edáfica por Cu, Cr y Zn, la estrategia de L. tenuis consistiría en regular la translocación de metales hacia vástago. La contaminación no afectaría la simbiosis con rizobios y HMA. Así, el cultivo de L. tenuis permitiría conservar la microbiota nativa, favoreciendo la posterior implantación de otras especies en suelos ribereños.; Phytoremediation involves the destruction, inactivation or stabilization of contaminants (e.g. heavy metals) by plants –and microorganisms associated with their roots–, and allows to improving soil quality. The ability of Lotus tenuis Waldst. & Kit. to absorb metals and associate with arbuscular mycorrhizal fungi (AMF) and native rhizobia from soils of the Matanza-Riachuelo Basin was studied. L. tenuis plants were grown in a greenhouse on riparian soils of Gral. Las Heras (S1), Marcos Paz (S2) and Avellaneda (S3) for 50 days. Fertility, total metals (ME-T) and soil spore density (SD) were quantified pre-sowing and at plant harvest. Shoot and root biomass, photosynthetic pigments, Cu, Cr, and Zn in shoot and root, AMF colonization, and root nodulation were measured. Metal translocation (TF) and bioconcentration (BCF) factors were calculated. Available phosphorus increased from S1 to S3 and decreased in S2 and S3 after harvest. ME-T and ME-DTPA were higher in S3 than in S1 and S2; they did not differ at harvest time. The SD decreased from S1 to S3. Biomass increased and pigments decreased from S1 to S3. AMF colonization did not significantly differ among sites. The number of nodules g-1 radical fresh weight was 9.7 in S1, 67.6 in S2 and 41.8 in S3. In general, the metal concentration was higher in roots than in shoots and the BCF decreased from S1 to S3. Faced with edaphic contamination by Cu, Cr and Zn, the strategy of L. tenuis would consist of regulating the translocation of metals towards the shoot. The contamination would not affect the symbiosis with rhizobia and AMF. Thus, the cultivation of L. tenuis would allow the conservation of the native microbiota, favoring the subsequent implantation of other species in riparian soils.

Explorando las celdas de combustible microbianas sedimentarias: Una herramienta educativa aplicada a la biorremediación de sedimentos; Exploring sedimentary microbial fuel cells: An educational tool applied to sediment bioremediation Juarez, Agustín; Pérgola, Martín Sebastián; Raiger Iustman, Laura Judith; Sacco, Natalia Jimena Actualmente existe una preocupación por desarrollar nuevas herramientas, y mejorar las ya existentes, para la biorremediación de cuerpos de agua o sedimentos contaminados. En este trabajo presentamos una potencial alternativa para la biorremediación de sedimentos, basada en el uso de celdas de combustible microbianas. Asimismo, presentamos una propuesta didáctica experimental sencilla para implementar el uso de celdas de combustibles microbianas en procesos de biorremediación, que plantea como desafío el abordaje de una problemática genuina y compleja, que implica un enfoque interdisciplinario y la integración de conceptos de microbiología, bioquímica, química y física. Encarar este tipo de problemáticas desde lo educativo supone la toma de decisiones en el diseño experimental (en este caso en el armado de la celda de combustible) que conlleva el desarrollo de competencias sumamente importantes para estudiantes de grado como futuros profesionales.; Currently there is a concern to develop new tools, and improve the existing ones, for the bioremediation of contaminated bodies of water or sediments. In this work we present a potential alternative for sediment bioremediation, based on the use of microbial fuel cells. Likewise, we present a simple experimental didactic proposal to implement the use of microbial fuel cells in bioremediation processes, which poses as a challenge the approach of a genuine and complex problem, which implies an interdisciplinary approach and the integration of concepts of microbiology, biochemistry, chemistry and physics. Facing this type of problem from an educational point of view involves decision-making in the experimental design (in this case in the assembly of the fuel cell) which implies the development of extremely important skills for undergraduate students as future professionals.

La Residencia como Espacio Integrador de Saberes: Ser practicante del Profesorado en Matemática de la UNR en 2020; Internships as an Integrating Space: Being an intern of the Math Teaching Program at the National University of Rosario, Argentina, in 2020 Rudi, Denise; Sgreccia, Natalia Fátima En el presente artículo se comparte lo realizado en las prácticas de Residencia en el Profesorado en Matemática de la Universidad Nacional de Rosario durante el año 2020, a través de la voz de una de las estudiantes que transitó esa experiencia. Los asuntos de interés giran en torno la gestión de entrada al terreno, la articulación de los contenidos en el nivel secundario, los intercambios con estudiantes, y emociones e interrogantes manifestados por la practicante en tal peculiar año.

Modelando el riesgo de incendios en Argentina – Una contribución a las políticas de manejo del fuego; Modeling fires' risk in Argentina – A contribution to public fire management policies Caride, Verónica Según FAO (2021), el 90% de los incendios son explicados por causas humanas. Resulta por tanto fundamental incluir en los sistemas de evaluación de peligro y alerta temprana de incendios forestales y rurales factores antrópicos. Si bien la Argentina posee un sistemade evaluación de peligro y alerta temprana de incendios forestales y rurales basado en el sistema canadiense, sólo estima 1 de sus 3 componentes, el Índice climático del fuego o FWI por sus siglas en inglés (Fire Weather Index). El sistema nacional omite el componente de predicción de ocurrencia, más conocido como FOP por sus siglas en inglés (Fire Occurrence Prediction), basado en variables antrópicas. Este artículo presenta un modelo econométrico de ocurrencia de incendios para Argentina, incorporando información antrópica a nivel departamental y controlando por variables meteorológicas. El objetivo es generar información que permita desarrollar un sistema que garantice la eficacia y eficiencia en el manejo del fuego. Los resultados alcanzados nos indicanque la actividad ganadera, las variables vinculadas a la calidad de vida, la densidad poblacional y la infraestructura vial tienen un impacto significativo sobre la ocurrencia de incendios. Como conclusión se puede afirmar que se recomienda para Argentinaque las políticas públicas de manejo del fuego se focalicen en incorporar estrategias de prevención a partir de una mayor concientización y control de los incendios realizados en los establecimientos ganaderos y en aquellas zonas aledañas a los centros poblacionales y accesos viales, así como en mejorar la calidad de vida de las poblaciones rurales.; According to FAO (2021), the 90% of fires are explained by human causes. It is therefore essential to include anthropic factors in forest and rural fire hazard assessment and early warning systems. Although Argentina has a forest and rural fire hazard assessment and early warning system based on the Canadian system, it only estimates 1 of its 3 components, the Fire Weather Index (FWI). The national system omits the component of fire occurrence prediction, better known as FOP, based on anthropic variables. This article presents an econometric model of fire occurrence for Argentina, incorporating anthropic information at the departmental level and controlling for meteorological variables. The objective is to generate information that allows the development of a system that guarantees the effectiveness and efficiency in fire management. The results achieved indicate that livestock activity, variables related to quality of life, population density and road infrastructure have a significant impact on the occurrence of fires. In conclusion, it can be stated that it is recommended for Argentina that public fire management policies focus on incorporating prevention strategies based on greater awareness and control of fires carried out in livestock farms and in those areas surrounding population centers and road access as well as on improving the quality of life of rural populations.

¿Cómo narrar un bosque? Imbricaciones entre artes y ciencias en la Isla Victoria; How to narrate a forest? Imbrications between arts and sciences on Isla Victoria Klier, Gabriela Ruth; Vargas, Maia El propósito de este manuscrito fue contribuir a la discusión por los vínculos entre artes y ciencias para las prácticas de cuidado ambiental y conservación de la biodiversidad partiendo desde la experiencia en el proyecto Laboratorio Isla Victoria. Esta isla, situada en el lago Nahuel Huapi, es un emblema ambiental histórico de Argentina, donde hace casi un siglo se instaló el arboreto más importante de la Patagonia y actualmente presenta numerosos proyectos de conservación. Se presentará un debate sobre la relación de las artes con las ciencias en el contexto de crisis ambiental, para luego, desde el caso de la Isla Victoria, recorrer ciertas preguntas y experiencias sobre los horizontes de estas aproximaciones en pos del cuidado ambiental.; The purpose of this manuscript is to contribute to the discussion on the links between arts and sciences in the practices of environmental care and biodiversity conservation. The starting point is the experience in Isla Victoria Laboratory project. This island, located in Nahuel Huapi Lake, is a historical environmental emblem, where a century ago the most important Arboretum in Patagonia was installed and where many conservation projects are currently being developed. The study presents a debate of de arts-sciences relationship in the context of environmental crisis, and hence, taking the case of Isla Victoria as a starting point, explores certain questions and experiences on the horizons of these approaches in pursuit of environmental care.

Bioeconomía: Análisis sobre los marcos de transición sostenibles; Bioeconomy: sustainable transition frameworks Perez, Santiago Agustin Los recursos naturales han sido y continúan siendo fuentes de crecimiento para la región de América Latina. A largo plazo, diversos autores plantean a la bioeconomía como un modelo estratégico clave para lograr el desarrollo sustentable de los territorios. Este sistema económico se centra en el uso sustentable de los recursos biológicos y renovables para garantizar la sostenibilidad. En este marco, se realiza una revisión de la investigación sobre la bioeconomía como modelo de desarrollo y antecedentes que articulen con los marcos de innovación posibles. A partir de esto se buscó identificar los factores contextuales que median y moderan esta relación y los desafíos futuros. Se examina la metodología de los estudios, los términos de innovación en sostenibilidad, los marcos de transición planteados y las variables fundamentales que inciden sobre el desarrollo de la bioeconomía. Los resultados revelan que la investigación se centra en países europeos. El marco de mayor utilización es la perspectiva multinivel. Las principales variables que enfatizan en la transición hacia la bioeconomía son los cambios tecnológico e institucional, políticas públicas y sectoriales con la integración de una amplia gama de redes de actores. Se plantea una necesidad de un análisis en profundidad de los desafíos y oportunidades que enfrenta la bioeconomía en América Latina, con una ampliación de perspectiva en los marcos de transición.; Natural resources have been and continue to be sources of growth for the Latin American region. In the long term, several authors propose the bioeconomy as a key strategic model to achieve the sustainable development of the territories. This economic system focuses on the sustainable use of biological and renewable resources to ensure sustainability. In this framework, a review of the research on the bioeconomy as a development model and background that articulates with the possible innovation frameworks is carried out. From this, we sought to identify the contextual factors that mediate and moderate this relationship and future challenges. The methodology of the studies, the terms of innovation in sustainability, the proposed transition frameworks and the fundamental variables that affect the development of the bioeconomy are examined. The results reveal that the research focuses on European countries. The most widely used framework is the multilevel perspective. The main variables that emphasize the transition to the bioeconomy are technological and institutional changes, public and sectoral policies with the integration of a wide range of actor networks. There is a need for an in-depth analysis of the challenges and opportunities facing the bioeconomy in Latin America, with a broadening of perspective in the transition frameworks.

Del uso legítimo de la fuerza a la violencia policial: Sentidos de la violencia en las interacciones entre la policía y la población durante la pandemia COVID 19. Mar del Plata, 2020-2021; From legitimate use of force to police violence: Meanings of violence in the interactions between the police and the population during the COVID 19 pandemic. Mar del Plata, 2020-2021 Lohiol, Gonzalo Jesús; Lorenc Valcarce, Federico Mario El presente artículo aborda las distintas formas de la violencia tal como son experimentadas en las interacciones locales entre la policía y la población, y narradas por unos y otros en el contexto de las entrevistas realizadas durante una investigación sociológica. En primer lugar, analizamos la manera en que la violencia es vivida e interpretada desde la perspectiva de los funcionarios policiales que trabajan en comisarías. En segundo lugar, consideramos la manera en que los pobladores de barrios periféricos perciben y evalúan el trabajo policial, y el lugar que las distintas formas de violencia policial ocupa en las narrativas ciudadanas. En conjunto, los testimonios de policías y pobladores son coincidentes a la hora de proyectar la imagen de un mundo cotidiano atravesado por violencias permanentes y de intensidad variable que circulan en múltiples direcciones, en diversos escenarios y con variados sentidos. Nuestro análisis se apoya en una veintena de entrevistas con personal policial de distinta jerarquía en diversas dependencias de la ciudad de Mar del Plata, y también en entrevistas con informantes clave, en particular, media docena de participantes en los foros de seguridad, militantes sociales y dirigentes políticos locales. Por otro lado, recuperamos a través de entrevistas la voz de medio centenar de pobladores de distintos barrios populares. El trabajo de campo se realizó desde mediados de 2020 hasta finales de 2021, en el contexto de la pandemia de COVID 19, en el momento inmediatamente posterior a la aplicación de las medidas más drásticas de aislamiento social obligatorio.; This article addresses the different forms of violence as they are experienced in local interactions between the police and the population, and then narrated by both in the context of interviews conducted during a sociological enquiry. In the first place, we analyze the way in which violence is faced and interpreted from the perspective of police officers. Second, we consider the way in which the population perceives and evaluates police work, and the place that the different forms of police violence occupy in citizen narratives. As a whole, the testimonies of police officers and residents coincide when it comes to projecting the image of a daily world crisscrossed by permanent violence of varying intensity that circulates in multiple directions, in manifold settings and with various meanings. Our analysis is based on twenty interviews with police personnel of different ranks in various police stations in the city of Mar del Plata, and on interviews with key informants, in particular, half a dozen participants in the security forums, social activists, and local political leaders. On the other hand, we recovered through interviews the voice of fifty residents of different neighborhoods of the city. The fieldwork was carried out from mid-2020 to the end of 2021, in the context of the COVID 19 pandemic, immediately after the application of the most drastic measures of mandatory social isolation.

Primer registro de Corbatita Blanco (Sporophila leucoptera) para la Provincia de Buenos Aires: Nueva evidencia de una posible expansión de su rango de distribución hacia el sur; First record of White-bellied Seedeater (Sporophila leucoptera) for Buenos Aires province: New evidence for a possible southward expansion of its range of distribution Loredo, María de los Ángeles; Martínez Curci, Natalia Soledad; Bachmann, Silvana; Isacch, Juan Pablo El Corbatita Blanco (Sporophila leucoptera) es una especie que se distribuye principalmente en el noreste de América del Sur incluyendo el centro y este de Brasil, el este de Paraguay y el noreste de Argentina. El 7 noviembre de 2021 observamos una pareja en la Reserva Natural Municipal Faro Querandí del partido de Villa Gesell, provincia de Buenos Aires, hecho que constituye el primer registro de Corbatita Blanco para la provincia. Nuestro registro y los hallazgos de los últimos años en Entre Ríos y Santa Fe, Argentina, sumados a un registro en el departamento de San José en Uruguay apoyan la hipótesis de que la especie estaría atravesando un proceso de expansión geográfica, ampliando su distribución hacia el sur.; White-bellied Seedeater (Sporophila leucoptera) is a species whose main distribution is in the northeast of South America including central and eastern Brazil, the east of Paraguay and the northeast of Argentina. On November 7th 2021 a couple was seen at Faro Querandí Municipal Natural Reserve of Villa Gesell district, Buenos Aires province, being the first record for the White-bellied Seedeater for the province. This record and recent years records in the Argentinian provinces of Entre Ríos and Santa Fe, and the record in San José Department of Uruguay support the hypothesis that the species is undergoing a process of geographic expansion, extending its distribution southwards.

Análisis comparativo de modelos digitales del terreno obtenidos con LiDAR aéreo y structure from motion: Aplicación en estudios del paisaje en el sitio inka El Shincal de Quimivil (Noroeste argentino); Comparative analysis of digital terrain models obtained with aerial LiDAR and Structure from Motion: Application in landscape studies at the Inka site El Shincal de Quimivil, Northwest Argentina Moralejo, Reinaldo Andres; López, Luciano; Gobbo, Juan Diego; del Cogliano, Daniel Hector En este trabajo se comparan los resultados de un relevamiento con LiDAR aéreo ystructure from motionen el sitioinkaEl Shincal de Quimivil. Este sitio se localiza en la provincia de Catamarca y es considera-do uno de los centros políticos, administrativos y ceremoniales incaicos más emblemáticos del Noroesteargentino. Para realizar esta comparación y explorar las potencialidades de ambas técnicas, se realizaroncálculos estadísticos de las diferencias de alturas y se llevaron a cabo análisis espaciales de visibilidad ymovilidad humana, entendidos respectivamente como la representación visual de un espacio y como lacapacidad de moverse a través de él. Las mayores diferencias se registraron en zonas con vegetación densay altas pendientes. Naturalmente, la referencia es el Modelo Digital del Terreno determinado con LiDAR,que no es afectado por esas circunstancias y tiene calidad de pocos centímetros en todas las componen-tes. En suelo desnudo, ambos modelos son comparables. Por lo tanto, una de las claves para la elecciónde estas técnicas es decidir el uso que le daremos a cada una ellas de acuerdo con el tipo de terreno, laescala del trabajo y el error que estamos dispuestos a aceptar.; This paper compares the results of a survey with aerial LiDAR and Structure from Motion at the Inka site El Shincal de Quimivil. This site is located in the province of Catamarca and is considered one of the most emblematic Inka political, administrative and ceremonial centres in the Northwest Argentina. In order to compare and explore the potential of both techniques, statistical calculations of height differences were made and spatial analysis of visibility and human mobility, understood respectively as the visual representation of a space and the ability to move through it, were carried out. The greatest differences were registered in areas with dense vegetation and high slopes. Naturally, the reference is the Digital Terrain Model determined with LiDAR, which is not affected by these circumstances and has a quality of a few centimetres in all components. On bare ground, both models are comparable. Therefore, one of the keys to choose between these techniques is to decide how to use each of them according to the type of terrain, the scale of work, and acceptable error.

Algunas aproximaciones al uso de la alegoría en los relatos artúricos: Un recorrido por diversos textos, territorios y modos de significar; Some Approaches to the Use of Allegory in Arthurian Narrative: A Journey through Various Texts, Territories, and Ways of Meaning Abeledo, Manuel La alegoría, entendida en su sentido retórico estricto como un procedimiento que produce la significación a través de una estructura de metáforas, es uno de los dispositivos retóricos más frecuentes en la Edad Media; sin embargo, casi no aparece en la literatura artúrica del período. el presente trabajo busca, a través del análisis de sus escasas apariciones, y de una serie de sistemas de equivalencias que se apoyan, aunque con fines diversos, en la forma alegórica, entender los procesos hermenéuticos que rigen estos pasajes, y los modos en que se articula la participación de los personajes y del lector en la administración informativa; The allegory, understood in its strict rhetorical sense as a procedure that produces signification through a structure of metaphors, is one of the most frequent rhetorical devices in the Middle Ages; nevertheless, it’s nearly absent in the Arthurian literature of the period. This work, through the analysis of the rare occasions in which allegory appears and of a series of equivalence systems that are based on the allegorical form (although with different purposes), aims to understand the hermeneutic procedures that rule those fragments, and the ways in which the participation of characters and of the reader in the administration of information is articulated.

Covalent coupling of Spike’s receptor binding domain to a multimeric carrier produces a high immune response against SARS-CoV-2 Berguer, Paula Mercedes; Blaustein, Matías; Bredeston, Luis María; Craig, Patricio Oliver; D'alessio, Cecilia; Elias, Fernanda; Farré, Paola C.; Fernández, Natalia Brenda; Gentili, Hernan Gustavo; Gándola, Yamila Belén; Gasulla, Javier; Gudesblat, Gustavo Eduardo; Herrera, Maria Georgina; Ibañez, Lorena Itatí; Idrovo Hidalgo, Tommy; Nadra, Alejandro Daniel; Noseda, Diego Gabriel; Pavan, Carlos Humberto; Pavan, Maria Florencia; Pignataro, María Florencia; Roman, Ernesto Andres; Ruberto, Lucas Adolfo Mauro; Rubinstein, Natalia; Sanchez Sanchez, Maria Victoria; Santos, Javier; Wetzler, Diana Elena; Zelada, Alicia Mercedes The receptor binding domain (RBD) of the Spike protein from SARS-CoV-2 is a promising candidate to develop effective COVID-19 vaccines since it can induce potent neutralizing antibodies. We have previously reported the highly efficient production of RBD in Pichia pastoris, which is structurally similar to the same protein produced in mammalian HEK-293T cells. In this work we designed an RBD multimer with the purpose of increasing its immunogenicity. We produced multimeric particles by a transpeptidation reaction between RBD expressed in P. pastoris and Lumazine Synthase from Brucella abortus (BLS), which is a highly immunogenic and very stable decameric 170 kDa protein. Such particles were used to vaccinate mice with two doses 30 days apart. When the particles ratio of RBD to BLS units was high (6–7 RBD molecules per BLS decamer in average), the humoral immune response was significantly higher than that elicited by RBD alone or by RBD-BLS particles with a lower RBD to BLS ratio (1–2 RBD molecules per BLS decamer). Remarkably, multimeric particles with a high number of RBD copies elicited a high titer of neutralizing IgGs. These results indicate that multimeric particles composed of RBD covalent coupled to BLS possess an advantageous architecture for antigen presentation to the immune system, and therefore enhancing RBD immunogenicity. Thus, multimeric RBD-BLS particles are promising candidates for a protein-based vaccine.
