La miniatura épica en el L. II de la Rusticatio Mexicana; The epic miniature in the Book II of the Rusticatio Mexicana Suarez, Marcela Alejandra En el vasto panorama de la literatura neolatina la poesía épica y la poesía didáctica ocupan el sitial más destacado dentro de la jerarquía de los géneros poéticos. En términos generales, comparten una serie de rasgos comunes tales como el mismo metro, la división en cantos, elaboradas comparaciones, largos pasajes descriptivos y narrativos. La Rusticatio Mexicana del jesuita novohispano Rafael Landívar, publicada en Bolonia en 1782, es un poema didáctico-descriptivo en el que se celebran las excelencias americanas a partir de la constitución previa de un modelo de competencia genérica surgido básicamente de las Geórgicas de Virgilio. Sin embargo, el poema también presenta algunos rasgos vinculados con la estructura épica. En esta ocasión nos detendremos en el L.II, que aborda la descripción de la erupción del volcán Jorullo, y analizaremos la miniatura épica en torno del éxodo de los lugareños, cuyo hipotexto es el relato virgiliano de la destrucción de Troya. Esta tímida filiación con el género épico está convalidada por un corpus de alusiones pertenecientes a la Eneida, que el propio Landívar activa asimilando de este modo la historia de los nativos a la de los troyanos y sentando las bases de una épica local que puede ser interpretada como el vehículo metafórico del exilio jesuítico.; In the vast panorama of Neo-Latin literature, epic poetry and didactic poetry occupy the most prominent place in the hierarchy of poetic genres. Broadly speaking, they share a number of common features such as the same metre, division into chants, elaborate comparisons, long descriptive and narrative passages. The Rusticatio Mexicana by the new spanish jesuit Rafael Landívar, published in Bologna in 1782, is a didactic-descriptive poem in which american excellences are celebrated based on the previous constitution of a model of generic competence that basically emerged from the Georgics of Virgil. However, the poem also has some features linked to the epic structure. On this occasion we will stop at book II, which deals with the description of the eruption of the Jorullo volcano, and we will analyze the epic miniature around the exodus of the locals, whose hypotext is the virgilian account of the destruction of Troy. This timid affiliation with the epic genre is validated by a corpus of allusions belonging to the Aeneid, which Landívar himself activates, thus assimilating the history of the natives to that of the trojans and laying the foundations of a local epic that can be interpreted as the metaphorical vehicle of the Jesuit exile.

Reflexiones teóricas sobre la construcción conceptual de las experiencias organizativas de las asambleas antiextractivistas de La Rioja, Argentina; Theoretical reflections on the conceptual construction of the organizational experiences of the anti-extractivist assemblies of La Rioja, Argentina Gasetúa, Erica Flavia Este escrito es una introducción a la construcción teórico-epistémica, que como asamblearia feminista antiextractivista e investigadora llevo adelante en una investigación de tesis doctoral y de la lucha colectiva desplegada en los lugares de vida que habito. Las categorías que se proponen reflexionar, están siendo (Kusch, 2007) pensadas en lucha y desde las urgencias que permanentemente azotan nuestros territorios signados como zonas de sacrificio para el neoextractivismo. En esta presentación el objetivo es problematizar la categoría de asambleas socioambientales, con especial atención en lo socioambiental, su circulación y la revisión del propio recorrido de reflexión conceptual en mis escritos.; This writing is an introduction to the theoretical-epistemic construction, which as an anti-extractivist feminist assembly member and researcher I carry out in a doctoral thesis research and the collective struggle deployed in the places of life that I inhabit. The categories that are proposed to reflect are being (Kusch, 2007) conceived in struggle and from the urgencies that permanently plague our territories marked as sacrifice zones for neo-extractivism. In this presentation the objective is to problematize the category of socio-environmental assemblies, with special attention to the socio-environmental, its circulation and the review of the journey of conceptual reflection in my writings.

A quantitative analysis of David Fabricius’ astronomical observations Grecco, Hernan Edgardo; Carman, Christian Carlos David Fabricius, a Reformed pastor in Ostfriesland, was highly regarded by Kepler as an exceptional observer, second only to Tycho Brahe. From 1596 to 1609, Fabricius engaged in extensive correspondence, exchanging numerous letters with Brahe and subsequently with Kepler. These communications also provided values for direct observations on meridian altitudes of planets and stars, as well as elongations between a planet and a star or between two stars. We provide a detailed summary of Fabricius’s observations and compare them with the prediction of twenty-first-century models. The analysis indicates that under specific conditions, his observations exhibit sub-arcminute deviations in relation to those calculated from modern theories. Our findings preliminarily indicate that Fabricius’ astronomical observational abilities were comparable to, an occasionally superior to, those of Brahe himself. We provide machine-readable tables of his observations.

To move or not to move: Dispersal of Orius insidiosus in strawberry plants Alonso, Mariángeles; Guisoni, Nara Cristina; Rocca, Margarita; Greco, Nancy Mabel Spatial and temporal distribution of food resources influences predatory insects´ foraging and dispersal behavior. Orius insidiosus (Say) (Hemiptera: Anthocoridae) is a good biological control agent of western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), in the strawberry crop and consumes two-spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), and pollen as well. Augmentative biological control programs may fail if, following release, predators disperse from the crop. We studied the dispersal of O. insidiosus as a function of pollen availability, density of their main prey WFT, and the presence of the alternative prey TSSM, within and between strawberry plants. We found that O. insidiosus remained on the flowers during the 24h of the assay. The dispersal of predators to a neighboring flower with thrips was approximately six times greater from a flower without pollen than from a flower with pollen. When TSSM was the only prey available, O. insidiosus colonized the leaves, and its dispersal within the plant was greater. At the plot scale, the predator dispersal from the release plant to other plants also depended on the presence of flowering plants and prey. Our results highlight the importance of flowering plants and pollen availability in enhancing the persistence of O. insidiosus in strawberry plants. Releases of this predator in the strawberry crop should be after the beginning of flowering, even at low WFT densities.

Elucidating solvent effects on lipase‐catalyzed peroxyacid synthesis through activity‐based kinetics and molecular dynamics Brandolin, Salvador Eduardo; Scilipoti, José Antonio; Magario, Ivana Peroxyacid synthesis is the first step in Prilezhaev epoxidation, which is an industrial method to form epoxides. Motivated by the development of a kinetic model as a tool for solvent selection, the effect of solvent type and acid chain length on the lipase-catalyzed peroxyacid synthesis was studied. A thermodynamic activity-based ping-pong kinetic expression was successfully applied to predict the effect of the reagent loadings in hexane. The activity-based reaction quotients provided a prediction of solvent-independent equilibrium constants. However, this strategy did not achieve satisfactory estimations of initial rates in solvents of higher polarity. The lack of compliance with some assumptions of this methodology could be confirmed through molecular dynamics calculations i.e. independent solvation energies and lack of solvent interaction with the active site. A novel approach is proposed combining the activity-based kinetic expression and the free binding energy of the solvent with the active site to predict kinetics upon solvent change. Di-isopropyl ether generated a strong interaction with the enzyme´s active site, which was detrimental to kinetics. On the other hand, toluene or limonene gave moderate interaction with the active site rendering improved catalytic yield compared with less polar solvents, a finding sharpened when peroctanoic acid was produced.

Vitamin D3 supplementation in COVID-19 patients with cardiovascular disease and gut dysbiosis Sanz, R. L.; García, F.; Gutierrez, A.; García Menéndez, Sebastián Marcelo Manuel; Inserra, F.; Ferder, L.; Manucha, Walter Ariel Fernando Background: The COVID-19 pandemic has highlighted the vulnerability of particular patient groups to SARS-CoV-2 infection, including those with cardiovascular diseases, hypertension, and intestinal dysbiosis. COVID-19 affects the gut, suggesting diet and vitamin D3 supplementation may affect disease progression. Aims: To evaluate levels of Ang II and Ang-(1-7), cytokine profile, and gut microbiota status in patients hospitalized for mild COVID-19 with a history of cardiovascular disease and treated with daily doses of vitamin D3. Methods: We recruited 50 adult patients and accessed pathophysiology study 22, randomized to daily oral doses of 10,000 IU vitamin D3 (n=11) or placebo (n=11). Plasma levels of Ang II and Ang-(1-7) were determined by radioimmunoassay, TMA and TMAO were measured by liquid chromatography and interleukins (ILs) 6, 8, 10 and TNF-α by ELISA. Results: The Ang-(1-7)/Ang II ratio, as an indirect measure of ACE2 enzymatic activity, increased in the vitamin D3 group (24±5 pg/mL vs 4.66±2 pg/mL, p<0.01). Also, in the vitamin D3-treated, there was a significant decline in inflammatory ILs and an increase in protective markers, such as a substantial reduction in TMAO (5±2 µmoles/dL vs 60±10 µmoles/dL, p<0.01). In addition, treated patients experienced less severity of infection, required less intensive care, had fewer days of hospitalization, and a reduced mortality rate. Additionally, improvements in markers of cardiovascular function were seen in the vitamin D3 group, including a tendency for reductions in blood pressure in hypertensive patients. Conclusions: Vitamin D3 supplementation in patients with COVID-19 and specific conditions is associated with a more favourable prognosis, suggesting therapeutic potential in patients with comorbidities such as cardiovascular disease and gut dysbiosis.

De las canteras al desarrollo sostenible: Visión actual del potencial geoeconómico de la minería en Entre Ríos, Argentina; From quarries to sustainable development: Current vision of the geoeconomic potential of mining in Entre Ríos, Argentina Pedersen, Oscar Ariel; Romero, María Isabel; Thalmeier, Maria Belen; Brunetto, Ernesto El presente trabajo aborda la necesidad imperativa de realizar un análisis geoeconómico exhaustivo de los recursos minerales en la provincia de Entre Ríos, Argentina.

Prevalence of congenital anomalies and prenatal diagnosis by birth institution (public vs. non-public): indicators of inequality in access to elective termination of pregnancy for fetal anomalies Brun, Paloma Laura; Groisman, Boris; Bidondo, Maria Paz; Barbero, Pablo Miguel; Trotta, Marianela; Liascovich, Rosa Congenital anomalies (CA) encompass all morphological or functional alterations originating prenatally and present at birth. The prenatal diagnosis of these anomalies can signifcantly impact the overall health of the pregnant individual and may infuence her decision regarding the continuation of the pregnancy. In contexts where safe pregnancy termination is not guaranteed by the state, it can lead to unsafe procedures with severe consequences. In our research, we analyzed epidemiological information on CA to develop potential indicators of inequity in access to safe abortion prior to the legalization of legal termination of pregnancy in Argentina. We included cases from 13 public hospitals and 9 non-public subsector hospitals, from the period 2013–2020. Two groups of specifc CA were selected: 1) CA capable of being prenatally diagnosed, and 2) CA related to vascular disruptive events. 10/18 of the selected CA capable of being prenatally diagnosed had a signifcantly higher prevalence in public hospitals (anencephaly, encephalocele, spina bifda, microcephaly, hydrocephalus, holoprosencephaly, hydranencephaly, diaphragmatic hernia, gastroschisis, bilateral renal agenesis). Non public hospitals had higher prenatal detection. Birth prevalence of CA related with vascular disruptive events (limb reduction, Moebius syndrome, amniotic band sequence) were signifcantly higher in public hospitals. These results suggest disparities in access to prenatal diagnosis and safe abortion based on socioeconomic status. There was a signifcant gap in access to prenatal diagnosis for CA and possibly to safe elective abortion depending on the type of institution (public vs. non-public).

Mapeo participativo de tecnologías de acceso al agua en el Chaco salteño (noroeste argentino): Avances de una experiencia colaborativa; Participatory mapping of water access technologies in the Chaco of Salta (northwest Argentina): Advances of a collaborative experience; Mapeamento participativo de tecnologias de acesso à água no Chaco de Salta (noroeste da Argentina): Avanços de uma experiência colaborativa López, Emilce de Las Mercedes; Belmonte, Silvina Conocer y mostrar espacialmente las distintas formas de acceso al agua en hábitats rurales del Chaco salteño, representa un gran desafío. Para enfrentarlo nos propusimos mapear esas formas de acceso al agua en la zona sistematizar los resultados e incorporarlos a un Sistema de Información Geográfica. La necesidad de este relevamiento surgió a partir de un trabajo colaborativo con las mesas locales de agua (Rivadavia Banda Norte) y de gestión local (La Unión – Rivadavia Banda Sur). Mediante técnicas de cartografía social se identificaron las principales formas de acceso al agua en los diversos parajes, puestos criollos y comunidades originarias de estos municipios. En el espacio provisto por las mesas locales se realizó una priorización que permitió ubicar espacialmente áreas de mayor necesidad de gestión del recurso hídrico. El uso de los sistemas de información geográfica tiene la ventaja de brindar una visión espacial e integral sobre el territorio y en este caso sobre la situación de acceso al agua, de potencial utilidad para la toma de decisiones informadas y la implementación de políticas hídricas efectivas en el Chaco salteño.; Knowing and spatially showing the different forms of access to water in the rural habitats of the Chaco de Salta represents a great challenge. To address this, we proposed to map these forms of access to water in the area, systematize the results and incorporate them into a Geographic Information System. The need for this survey arose from collaborative work with local groundwater (Rivadavia Banda Norte) and local management (La Unión – Rivadavia Banda Sur). Using social mapping techniques, the main forms of access to water in different locations, creole posts and communities originating in these municipalities were identified. In the space provided by the local tables, a prioritization was carried out that made it possible to spatially locate the areas most in need of water resources management. The use of geographic information systems has the advantage of providing a spatial and comprehensive view of the territory and, in this case, the water access situation, potentially useful for making informed decisions and affective water policies in the Chaco de Salta.; Conhecer e mostrar espacialmente as diferentes formas de acesso à águanos habitats rurais do Chaco de Salta representa um grande desafio. Para enfrentá-lo, propusemos mapear essas formas de acesso à água na área, sistematizar os resultados e incorporá-los em um Sistema de Informação Geográfica. A necessidade deste levantamento surgiu do trabalho colaborativo com os lençóis freáticos locais (Rivadavia Banda Norte) e a gestão local (La Unión –Rivadavia Banda Sur). Utilizando técnicas de mapeamento social, foram identificadas as principais formas de acesso à água nos diversos locais, postos crioulos e comunidades originárias desses municípios. No espaço disponibilizado pelas tabelas locais, foi realizada uma priorização que permitiu localizar espacialmente as áreas de maior necessidade de gestão de recursos hídricos. A utilização de sistemas de informação geográfica tem a vantagem de proporcionar uma visão espacial e abrangente do território e, neste caso, da situação de acesso à água, potencialmente útil para a tomada de decisões informadas e a implementação de políticas hídricas eficazes no Chaco de Salta.

Transformaciones y continuidades en la gestión policial de conflictividades durante la pandemia: El caso de Villa María (Córdoba, Argentina); Transformations and continuities in the police management of conflicts during the pandemic: The case of Villa María (Córdoba, Argentina) Goldin, Déborah Judith; Rodríguez, Florencia Este artículo presenta los resultados de una investigación sobre las transformaciones en las prácticas de policiamiento y control poblacional durante la pandemia por el COVID-19, y los modos en que estos cambios fueron experienciados por los y las policías de Córdoba (Argentina), en el caso del aglomerado Villa María-Villa Nueva durante los años 2020-2021. Aquí abordaremos las conflictividades que fueron relevantes en la localidad durante este período, analizando las transformaciones que se identificaron en las prácticas policiales y sus modos de intervención sobre estos conflictos. Luego, analizaremos las interacciones entre policía y ciudadanía, buscando evidenciar las transformaciones de este vínculo de por sí heterogéneo. Finalmente, indagaremos en las experiencias de los y las policías durante la pandemia, con especial énfasis en su percepción del riesgo y del reconocimiento de su labor, como así también sobre el uso de la fuerza. A partir de este recorrido, consideramos que la pandemia fortaleció el papel de la policía en la gestión poblacional, evidenciando aún más la realización de un abanico de tareas desvinculadas de la persecución del crimen.; This article presents the results of a research on the transformations in policing practices and population control during the COVID-19 pandemic, and the ways in which these changes were experienced by police officers in Córdoba (Argentina), in the case of the Villa María-Villa Nueva urban agglomerate during 2020-2021. Here we will address the conflicts that were relevant in this location during said period, analyzing the transformations that were identified in police practices and their ways of intervening in these conflicts. We analyze the interactions between police and citizens, looking to highlight the transformations of this already heterogeneous relation. Finally, we will inquire into the experiences of the police during the pandemic, with special emphasis on their perception of risk and recognition of their work, as well as on the use of force. On this basis, we consider that the pandemic strengthened the role of the police in population management, further highlighting the performance of a range of tasks unrelated to the prosecution of crime.

Episodicity in accretion-ejection processes associated with IRAS 15398-3359 Guzmán Ccolque, Estrella; Fernandez Lopez, Manuel; Vazzano, María Mercedes; de Gregorio, I.; Plunkett, A.; Santamaría Miranda, A. Context. The protostar IRAS 15398-3359 is associated with a bipolar molecular outflow ejected in an nearly northeast–southwest (NE–SW) direction, which has been extensively studied. Previous episodic accretion events have been suggested by this source. Furthermore, the analysis of the morphology and kinematics of the molecular outflow revealed the presence of four 12CO (2–1) bipolarelliptical shock-like structures identified in both lobes. These structures seem to trace different ejections inclined ∼10◦from each otheron the plane of the sky. This led to the hypothesis that the outflow axis likely precesses and launches material episodically. Aims. Since several authors reached the conclusion of the same episodicity scenario by independent observations, IRAS 15398-3359has become an ideal target to empirically analyze the relationship between accretion and ejection processes.Methods. We analyzed ALMA archive observations in Band 6, revealing the presence of low-velocity (<3.5 km s−1) emission fromthe 12CO (2–1) line to the south and north of the protostar. We studied the morphology and kinematics of the gas; our study seems tosupport the hypothesis of a precessing episodic outflow.Results. The ALMA observations reveal a north–south (N–S) outflow most likely associated with the IRAS 15398-3359 protostellarsystem. This outflow could be older than the well-studied NE–SW outflow. The orientation of the N–S outflow is 50◦–60◦ on the planeof the sky away from that of the NE–SW outflow. We also analyzed the spectral energy distribution of a far away young star andpreliminarily discard it as the driver of the SE outflow remnants. Conclusions. The new observations support the hypothesis of strong episodic accretion-ejection events in IRAS 15398-3359, accompanied by dramatic changes in the orientation of its ejection axis, implying that all the outflows in the region may have been driven bythe same protostar

UVC-LED assisted photo-Fenton/peroxydisulfate processes for microcontaminant and bacteria removal in a continuous flow reactor according to EU 2020/741 Benzaquén, Tamara Belén; Pichel, Natalia; Soriano Molina, Paula; Casas López, José Luis; Li Puma, Gianluca; Sánchez Pérez, José Antonio Bacteria inactivation (Escherichia coli (E. coli), total coliforms, Clostridium perfringens (C. perfringens)) and simultaneous removal of ubiquitous microcontaminants in actual municipal wastewater treatment plant secondary effluents was investigated at neutral pH using the UVC-LED assisted photo-Fenton reaction system operated in continuous flow. E. coli concentration ≤ 10 CFU/100 mL and 38 % microcontaminant removal was achieved in the reaction system at a hydraulic residence time of 30 min. UVC light alone and UVC light combined with an oxidant source (hydrogen peroxide, H2O2, or peroxydisulfate, S2O82−) were found to have a predominant effect on disinfection, meeting the EU 2020/741 validation (≥5 log10 reduction) and monitoring (≤10 CFU/100 mL) targets for both E. coli and C. perfringens after 30 min of treatment in batch mode. However, in the presence of either 0.05 or 0.1 mM of ferric nitrilotriacetate (Fe3+-NTA) the bacteria inactivation kinetics decreased due to reduced UVC light penetration along the water depth. In contrast, microcontaminant removal was accelerated using 0.05 or 0.1 mM of Fe3+-NTA and 1.47 mM H2O2. Overall, the results revealed that the treatment conditions favouring microcontaminant removal hindered disinfection and vice versa, and that the disinfection levels of C. perfringens (≤102 CFU/100 mL) reached in the batch mode experiments could not be attained under the continuous flow regime. This points out the need of performing disinfection experiments under continuous flow operation, as shown in the present study to determine the disinfection performance of UVC-LED assisted photo-Fenton reaction systems.

Las fronteras entre filosofía y religión en el pensamiento ricoeuriano: Un diálogo a propósito del problema del mal; The boundaries between philosophy and religion in Ricoeur’s thought: A dialogue on the problem of evil González, Daiana Marlén Nuestro trabajo propone un análisis de las ideas de libertad, mal y perdón a fin de transitar la frontera entre el discurso propiamente filosófico y el discurso religioso o kerigmático en la obra de Paul Ricoeur. El paso por estas ideas nos permitirá distinguir tres formas de contacto posibles entre filosofía y religión. Así, hablaremos en un primer momento de una aproximación; luego, trataremos de definir la frontera o separación que Ricoeur establece entre ambas a partir de la cuestión de la hermenéutica y, finalmente, plantearemos la posibilidad de un olvido de las fronteras propiciado por el problema del perdón y de la falta. Teniendo como eje principal el problema del mal en el pensamiento del filósofo francés nuestra tesis principal será sostener que con la propuesta del perdón difícil culmina un diálogo entre filosofía y religión en donde las fronteras entre una y otra se desvanecen.; This paper offers an analysis of the ideas of freedom, evil and forgiveness in order to cross the border between the philosophical discourse itself and the religious or kerygmatic discourse in Paul Ricoeur’s work. By passing through these ideas, we will be able to distinguish three possible forms of contact between philosophy and religion. Thus, we will first talk about an approximation; then, we will try to define the border or separation that Ricoeur establishes between the two based on the question of hermeneutics. Finally, we will raise the possibility of a forgetting of borders brought about by the problem of forgiveness and fault. Having as its main axis the problem of evil in the thought of the French philosopher, our main thesis will be to argue that with the proposal of difficult forgiveness culminates a dialogue between philosophy and religion in which the boundaries between one and the other vanish.

Chemical abundances of LINER galaxies - nitrogen abundance estimations Oliveira, C. B.; Krabbe, Angela; Dors, Oli L.; Zinchenko, I. A.; Hernandez Jimenez, Jose Andres; Cardaci, Monica Viviana; Hägele, Guillermo Federico; Ilha, G. S. In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscopic data (3600 - 10000 Å) of 40 LINERs from the Mapping Nearby Galaxies (MaNGA) survey were considered. Only objects classified as retired galaxies, i.e. whose main ionization sources are post-Asymptotic Giant Branch (pAGB) stars, were selected. The abundance estimates were obtained through detailed photoionization models built with the CLOUDY code to reproduce a set of observational emission line intensities ratios of the sample. Our results show that LINERs have oxygen and nitrogen abundances in the ranges of 8.0≲12+log(O/H)≲9.0 (mean value 8.74 ± 0.27) and 7.6≲12+log(N/H)≲8.5 (mean value 8.05 ± 0.25), respectively. About 70% of the sample have oversolar O/H and N/H abundances. Our abundance estimates are in consonance with those for Seyfert 2 nuclei and H II regions with the highest metallicity, indicating that these distinct object classes show similar enrichment of the interstellar medium (ISM). The LINERs in our sample are located in the higher N/O region of the N/O versus O/H diagram, showing an unexpected negative correlation between these two parameters. These results suggest that these LINERs mainly exhibit a secondary nitrogen production and could be acting some other mechanisms that deviate them from the usual theoretical secondary nitrogen production curve and the H II regions observations. However, we did not find any evidence in our data able to support the literature suggested mechanisms. On the other hand, our results show that LINERs do not present any correlation between the N/O abundances and the stellar masses of the hosting galaxies.

Impact of Parenteral Maternal Supplementation with Trace Minerals and Vitamins on Neonatal Calf Antioxidant System and Growth in a Dairy Herd Miqueo, Evangelina; Mattioli, Guillermo Alberto; Moore, Dadin Prando; Bilbao, María Guillermina; Moran, Karen Daiana; Relling, Alejandro Enrique Oxidative stress may affect new born calves due to high stress suffered around birth. We hypothesized that maternal supplementation with micronutrients and vitamins in late gestation enhance the neonatal calf’s antioxidant system, decreasing the occurrence and duration of diarrhea, and improving growth from birth through weaning. To test this hypothesis, 80 multiparous cows were cluster-assigned to treatment groups. Treated group (TG) cows received mineral and vitamin supplementation while control group (CG) cows received saline solution. Feed intake and fecal score were measured daily until the ninth week. Weight and body measurements were registered weekly, and blood samples were collected from postpartum cows and calves after birth and at 7, 14, and 63 days of life. Although CG calves had greater fecal scores (p = 0.01), diarrhea characteristics did not differ. Calves in the TG showed greater starter intake (p = 0.04). Feed efficiency showed a trend with treatment-age interaction (p = 0.06). Calves in the CG had wider hips in the first week (p = 0.03), but not by the ninth week. Total antioxidant status, thiobarbituric acid reactive substances, and haptoglobin did not differ between treatment groups. Serum metabolites showed no differences. Supplementation did not impact calf antioxidant system or growth in the first two months.

First bioprospecting study of skin host: Defense peptides in Odontophrynus americanus Cancelarich, Natalia Lorena; Arrulo, Miriam; Gugliotti, Sariah Trillo; Barbosa, Eder A; Moreira, Daniela; Basso, Nestor Guillermo; Perez, Luis Orlando; Teixeira, Cátia; Gomes, Paula; de la Torre, Beatriz G.; Albericio, Fernando; Eaton, Peter; Leite, José Roberto de Souza Almeida; Marani, Mariela Mirta The amphibians adaptation to diverse environments is closely related to the characteristics of their skin. The complex glandular system of frogs skin plays a pivotal role in enabling these animals to thrive in both aquatic and terrestrial habitats, and comprise crucial functions such as respiration, water balance, as well as serving as a defensive barrier due to the secretion of bioactive compounds. We herein report the first investigation on the skin secretion of O. americanus, as a potential source of bioactive peptides and also as an indicator of its evolutionary adaptations to changing environments. Americanin-1 was isolated and identified as a neutral peptide exhibiting moderate antibacterial activity against E. coli. Its amphipathic sequence including 19 amino acids and showing a propensity for alpha-helix structure, is discussed. Comparisons of the histomorphology of the skin of O. americanus with other previously documented species within the same genus revealed distinctive features in the Patagonian specimen, differing from conspecifics from other Argentine provinces. The presence of the Eberth-Katschenko layer, a prevalence of iridophores, and the existence of glycoconjugates in its serous glands, suggest that the integument is adapted to retain skin moisture. This adaptation is in line with the prevailing aridity of its native habitat.

Azúcar, historia y patrimonio industrial en el oriente tucumano: lugares de memoria de Lastenia (noroeste argentino); Açúcar, história e patrimônio industrial no oriente tucumano: lugares de memória de Lastenia (noroeste argentino); Sugar, history, and industrial heritage in eastern Tucumán: sites of memory of Lastenia (northwest Argentina) Villar, Fernando Andrés; Ataliva, Víctor Hugo El ingenio azucarero Lastenia (Tucumán, Argentina) cerró sus puertas el 22 de agosto de 1966 tras anunciarse el decreto-ley 16.926, impulsado por un gobierno de facto autodenominado Revolución Argentina. Con una profunda trayectoria en el territorio que actualmente comprende la localidad homónima, ese espacio productivo marcó su desarrollo social, económico y cultural. Aunque desde el punto de vista urbano la localidad de Lastenia es concebida como un componente más del aglomerado Gran San Miguel de Tucumán, se trata de un escenario dinámico con particularidades propias, un territorio jalonado por sitios que remiten a los procesos identitarios locales. Presentamos una primera aproximación a los espacios sociales que, desde las representaciones de vecinas y vecinos de la localidad, se comportan como fundantes y diacríticos de la identidad lasteniense. En este trabajo confluyen, además, los resultados parciales de proyectos de investigación realizados desde el año 2013 que en líneas generales impulsan la revalorización de los recursos culturales del oriente tucumano desde una perspectiva situada.; Em 22 de agosto de 1966, o engenho de açúcar Lastenia (Tucumán, Argentina) fechou suas portas após o anúncio do Decreto-lei n.º 16.926, impulsionado por um governo de fato autodenominado Revolução Argentina. Com uma história profunda no território que atualmente compreende a localidade homônima, esse espaço produtivo moldou seu desenvolvimento social, econômico e cultural. Embora do ponto de vista urbano a localidade de Lastenia seja concebida apenas como mais um componente da área metropolitana de Grande São Miguel de Tucumán, é um cenário dinâmico com suas próprias particularidades, um território marcado por locais que evocam processos de identidade locais. Apresentamos uma primeira abordagem dos espaços sociais que, com base nas perspectivas dos moradores da cidade, se comportam como elementos fundamentais e diacríticos da identidade lasteniense. Além disso, este trabalho integra resultados parciais de projetos de pesquisa realizados desde 2013 que, em termos gerais, promovem a revalorização de recursos culturais no leste de Tucumán numa ótica situada.; In the year 1966, on August 22nd, the Lastenia sugar mill (Tucumán, Argentina) shut its doors following the announcement of decree-law no. 16.926, driven by a self-proclaimed de facto government named the Argentine Revolution. With a profound history in the territory that currently encompasses the homonymous locality, this productive space shaped its social, economic, and cultural development. Although from an urban perspective the locality of Lastenia is conceived as just another component of the Greater San Miguel de Tucumán metropolitan area, it is actually a dynamic setting with its own particularities, a territory marked by sites that evoke local identity processes. We present a first approach to the social spaces that, from the perspectives of the town’s residents, behave as foundational and diacritical elements of the Lastenian identity. Additionally, this work integrates partial results from research projects conducted since 2013 that, in general terms, promote the revaluation of cultural resources in eastern Tucumán from a situated perspective

Impact of Germination Treatment and Quinoa Variety on the Physicochemical and Rheological Properties of Wheat Dough Guardianelli, Luciano Martin; Salinas, Maria Victoria; Puppo, Maria Cecilia The objective of this study was to analyze wheat dough blended with two varieties of quinoa flour (white-WQ, red-RQ),both germinated and non-germinated, to predict the technological behavior of the dough during the breadmaking process.Blends with wheat flour with quinoa flour: germinated (WQG or RQG) and ungerminated (WQ or RQ), at different levels(up to 25%) were formulated. Farinographic parameters and wet and dry gluten content were determined. Additionally,hydration (moisture, water activity, molecular mobility) and rheological (texture, relaxation) properties of the dough wereassessed. Fermentation parameters (maximum volume of fermented dough-DVmax and optimum fermentation time-tf) weredetermined. Dough properties were modified by the addition of quinoa: wheat dough with 25% quinoa flour resulted inlower gluten content and a less structured dough with high moisture. The elasticity and hardness of the dough were higherwith 25% germinated quinoa (WQG25 and RQG25). The adhesiveness of the dough depended on the variety and treatment,with RQG being more adhesive. Incorporating 25% quinoa flour of both varieties allowed a fast fermentation (shorter time)but with different kinetic. Although there were no differences between WQ25 and WQG25, RQG25 dough was more stablecompared to RQ25.Overall, satisfactory dough technological properties for baked goods production were observed for wheatdough containing up to 25% quinoa flour, independently if seeds were or were not previously germinated.

Se recuperan aportes teóricos del psicoanálisis, el ámbito educativo y la sociología para realizar una aproximación situada a la manera en que se entraman las presencias institucionales en el relato de vida de un joven de 18 años de edad. Los resultados resaltan la capacidad que tienen los vínculos institucionales de producir interrupciones en procesos desubjetivantes en curso y abrir a nuevos horizontes de vida, a partir de apuntalar la re-elaboración de experiencias traumáticas y la recomposición de un tejido sociosimbólico subjetivante.; O artigo apresenta reflexões e articulações conceituais sobre as funções subjetivantes realizadas por profissionais de instituições sociais e educativas no acompanhamento de jovens em contextos de precariedade. São recuperadas contribuições teóricas da psicanálise, da educação e da sociologia, para realizar uma abordagem situada sobre como as presenças institucionais se entrelaçam na narrativa de vida de um jovem de 18 anos. Os resultados destacam a capacidade dos vínculos institucionais de produzir interrupções em processos dessubjetivantes em curso e abrir novos horizontes de vida, ao apoiar a re-elaboração de experiências traumáticas e a recomposição de um tecido sociossimbólico subjetivante.; This paper presents conceptual reflections regarding the subjectification functions performed by professionals in social and educational institutions when supporting youth in contexts of precarity. Drawing on an interdisciplinary approach, it incorporates theoretical contributions from psychoanalysis, education, and sociology. The life story of an 18-year-old youth is analyzed, providing a situated approach to how institutional presences are interwoven into their biographical trajectory. The results highlight the capacity of institutional relationships to produce interruptions in processes of desubjectivation, opening up new horizons of life.
