Elecciones en Uruguay: algunas claves para analizar la segunda vuelta y el surgimiento de ''nuevos'' actores de derecha Mercado, Ana Belen “Cambiar está bueno” y “Lacalle Pou es Macri” son consignas que se leen por Montevideo. El 27 de octubre, mientras en la Argentina se festejaba el triunfo de la fórmula Fernández-Fernández, en Uruguay se oficializaba la segunda vuelta. Esta elección es particular en varios aspectos que intentaremos desarrollar en este artículo . Existe un proceso de desgaste del Frente Amplio que tras 15 años de gobierno lo hace receptor de críticas y demandas insatisfechas. La economía no crece al ritmo que lo hizo durante las administraciones anteriores, la tasa de desempleo es la más alta de los últimos 12 años (9,47%) y existe un alto nivel de endeudamiento -63,4% del PBI en 2018 . Esto no significa un retorno del electorado a los partidos tradicionales, sino que emergen nuevos actores políticos que capitalizan el descontento desde la derecha. Así surge Cabildo Abierto, una fuerza de derecha cuyo candidato, Guido Manini Ríos, es el excomandante en jefe de las fuerzas armadas. Esto lleva a considerar el avance de las derechas mediante distintas estrategias (electorales partidarias, no partidarias, no electorales) en un proceso regional más amplio.

A general method to produce mesoporous oxide spherical particles through an aerosol method from aqueous solutions Zelcer, Andrés; Franceschini, Esteban Andrés; Lombardo, Maria Veronica; Lanterna, Anabel Estela; Soler Illia, Galo Juan de Avila Arturo Mesoporous transition metal oxides (MTMO) with large surface area, nanocrystalline framework, and controlled porosity have brilliant prospects in fields such as energy, environment, catalysis, or nanomedicine. However, the green, reproducible, and scalable production of MTMO are still a bottleneck for their industrial applications. Although spray-drying methods permit to obtain MTMO in a potentially scalable fashion, the use of highly acidic alcoholic precursor solutions presents two main limitations: corrosion and flammability, which hinder their production in large quantities and lower cost. In this work, we present a general, reproducible, simple, and environment-friendly aerosol method for the synthesis of spherical MTMO particles from mildly acidic aqueous solutions. Acetylacetonate and acetate are used as condensation-controlling agents. Mixed oxides of high valence cations (M(IV) such as Ti, Zr, Ce, and their mixed oxides) were prepared with a yield over 95%, virtually without changing the formulation of the precursor mixture, which can be extended potentially to M(III) or M(V) oxides. The replacement of organic solvents by water allows working in air atmosphere, making this approach much safer, cheaper and environmentally friendly than the current aerosol-based routes. We also present the beneficial effect of mesoporous titania spheres as an additive to nickel electrodes used in the hydrogen evolution reaction, as a demonstrator to potential applications. A threefold increase in the electrocatalytic hydrogen production is observed in mesoporous titania-modified nickel electrodes with respect to a pure nickel catalyst. This performance can be further improved ~25% upon UVA-visible irradiation, due to the photoelectrocatalytic effect of the mesoporous TiO2.

Taxonomic revision of Chusquea subg. Magnifoliae and Chusquea subg. Platonia (Poaceae, Bambusoideae, Chusqueinae) in Peru Guerreiro, Carolina Inés; Alegría Olivera, J. José; Vega, Andrea Susana Subtribe Chusqueinae was previously composed of the genera Neurolepis and Chusquea. Following molecular-based phylogenetic studies, all species of Neurolepis were transferred to Chusquea and placed in two new subgenera: Magnifoliae and Platonia. Complete keys for the identification of taxa within C. subg. Magnifoliae and C. subg. Platonia are lacking. The present paper provides five new reports and a taxonomic revision of Chusquea subg. Magnifoliae and C. subg. Platonia in Peru involving 13 taxa. Vegetative and reproductive morphological diagnostic characters were analyzed. Complete illustrations of C. aristata, C. fimbriligulata subsp. peruviana, and C. spectabilis are provided. Chusquea elata, C. fimbriligulata subsp. fimbriligulata, C. mollis, C. nana, and C. spectabilis constitute new reports for Peru. On the basis of morphological comparative studies, keys for the identification of the species of Chusquea subg. Magnifoliae and C. subg. Platonia occurring in Peru were prepared based on vegetative and reproductive characters and are here presented for the first time.

Primer registro de Oligosarcus pintoi campos, 1945 (Characiformes, Characidae) en aguas continentales de Argentina; First record of Oligosarcus pintoi Campos, 1945 (Characiformes, Characidae) in freshwater courses of Argentina Almirón, Adriana; Bogan, Sergio; Cardoso, Yamila Paula; Ciotek, Liliana; Giogis, Pablo; Casciotta, Jorge Rafael Actualmente la biodiversidad íctica conocida del Parque Nacional Iguazú comprende 104 especies, de las cuales dos corresponden a especies de “dientudos” del género Oligosarcus: O. longirostris y O. menezesi. En esta contribución se da a conocer una tercera especie de este género registrada dentro de dicho parque: Oligosarcus pintoi. Este nuevo hallazgo es de relevancia porque, además, constituye el primer reporte de esta especie en Argentina en la cuenca del río Paraná medio.; Currently the known ichthyological biodiversity of the Iguazú National Park is composed by 104 species, two of which correspond to species of “dientudos” of the genus Oligosarcus: O. longirostris and O. menezesi. In this contribution, it is reported within the Park a third species of that genus: Oligosarcus pintoi. This new finding is relevant because it constitutes the first record of the species both in Argentina and in the middle Paraná River basin.

Scale-up of milling in a 100 liter device for processing of TiFeMn alloy for hydrogen storage applications: procedure and characterization Bellosta von Colbe, José; Puszkiel, Julián Atilio; Capurso, Giovanni; Franz, Andreas; Ulrich Benz, Hans; Zoz, Henning; Klassen, Thomas; Dornheim, Martin In this work, the mechanical milling of a FeTiMn alloy for hydrogen storage purposes was performed in an industrial milling device. The TiFe hydride is interesting from the technological standpoint because of the abundance and the low cost of its constituent elements Ti and Fe, as well as its high volumetric hydrogen capacity. However, TiFe is difficult to activate, usually requiring a thermal treatment above 400 °C. A TiFeMn alloy milled for just 10 minutes in a 100 liter industrial milling device showed excellent hydrogen storage properties without any thermal treatment. The as-milled TiFeMn alloy did not need any activation procedure and showed fast kinetic behavior and good cycling stability. Microstructural and morphological characterization of the as-received and as-milled TiFeMn alloys revealed that the material, presents reduced particle and crystallite sizes, even after such short time of milling. The refined microstructure of the as-milled TiFeMn is deemed to account for the improved hydrogen absorption-desorption properties.

Human sperm decondensation in vitro is related to cleavage rate and embryo quality in IVF Galotto, Camila; Cambiasso, Maite Yael; Julianelli, Vanina Laura; Rey Valzacchi, Gaston Javier; Rolando, R. N.; Rodriguez, M. L.; Calvo, L.; Calvo, Juan Carlos; Romanato, Marina Purpose: To investigate whether the ability of human spermatozoa to decondense in vitro in the presence of heparin (Hep) and glutathione (GSH) is related to assisted reproduction (ART) success. Methods: Cross-sectional pilot study involving male partners of 129 infertile couples undergoing ICSI with (45) or without (84) donor oocytes at two infertility clinics in CABA, Argentina, between October 2012 and December 2013. In vitro decondensation kinetics with Hep and GSH and DNA fragmentation (TUNEL) were determined on the same sample used for ICSI. The possible relationship of decondensation parameters (maximum decondensation and decondensation velocity) and TUNEL values with ART success was evaluated. Results: Embryo quality correlated positively with decondensation velocity (D60/D30) (Spearman?s correlation, p < 0.05). According to D60/D30 values, patients were classified as slow decondensers (SlowD) (n = 68) or fast decondensers (FastD) (n = 61). Embryo quality was better in FastD (unpaired t test, p < 0.05). FastD and SlowD were subdivided according to use of donor oocytes. Among SlowD, biochemical and clinical pregnancy rates per transfer were significantly higher in donor (n = 19) vs. in non-donor (n = 31) cycles (Fisher?s exact test, p < 0.05). TUNEL values were not related to embryo quality, but no clinical pregnancies or live births were achieved in TUNEL+ SlowD (n = 7). Conclusion: Decondensation kinetics of human spermatozoa in vitro with Hep and GSH could be related to embryo quality and ART success.

Patrones alimentarios de adultos mayores en una región argentina y su relación con factores socioeconómicos; Dietary patterns of older adults in an Argentine region and their relationship with socioeconomic factors Geri, Milva; Gutierrez, Emiliano Martin; González, Gisela Paula Objetivos Estudiar los patrones de consumo de alimentos en adultos mayores de la provincia de Buenos Aires (Argentina) y relacionarlos con factores socioeconómicos. Métodos A partir de la Encuesta Nacional de Gasto de los Hogares (2012-2013) se efectúa un análisis de componentes principales para encontrar y describir patrones alimentarios adoptados por hogares de la provincia de Buenos Aires habitados por adultos mayores. Mediante pruebas de diferencia de media y proporciones, se establecen relaciones entre el puntaje de los hogares en cada patrón alimentario, el ingreso promedio y la condición de vivir solo o sola. Resultados En función de las cargas factoriales asociadas a cada grupo alimentario, los patrones que, en conjunto, explican el 44,6% de la varianza total son: i) dieta variada tradicional, ii) dieta antiproteica, iii) dieta vegetariana y iv) dieta de hidratos de carbono. Se encuentra que el nivel de ingreso y la condición de vivir solo(a) son factores que podrían estar asociados a la adopción (o no) de la dieta variada tradicional, patrón alimentario recomendado por las guías alimentarias para la población argentina. Discusión La menor frecuencia de hogares habitados por adultos mayores solos y el menor nivel de ingreso promedio de los hogares que presentan un elevado puntaje en la dieta variada tradicional, podría ser utilizada por las autoridades sanitarias a la hora de tomar medidas tendientes a mejorar los patrones alimentarios de los adultos mayores que viven solos y cobran la pensión mínima.; Objectives To study the patterns of food consumption in older adults in the province of Buenos Aires (Argentina) and relate them to socioeconomic factors. Methods Based on the National Household Expenditure Survey (2012-2013), an analysis of main components is carried out to find and describe dietary patterns adopted by households in the province of Buenos Aires habited by older adults. Through tests of mean difference and proportions, relationships between household scores in each food pattern, average income and living alone or alone are established. Results Depending on the factor loads associated with each food group, the patterns that together explain 44.6% of the total variance are: i) traditional varied diet, ii) anti-protein diet, iii) vegetarian diet and iv) carbohydrate diet. It is found that the level of income and the condition of living alone are factors that could be associated with the adoption (or not) of the traditional varied diet, food pattern recommended by the dietary guidelines for the Argentine population. Discussion The lower frequency of households habited by older adults alone and the lower average income level of households that have a high score in the traditional varied diet, could be used by health authorities when taking measures to improve the eating patterns of older adults who live alone and receive the minimum pension.

The paradigm of ground meat as source of STEC in high risk area of HUS from Argentina Broglio, Alicia Susana; Bentancor, Adriana Beatriz Objectives: The aim of this work is to evaluate ground meat as infection source of Shiga toxin-producing Escherichia coli (STEC) to population of Tierra del Fuego, Argentina.Background: Argentina is the country with the highest rate of hemolytic uremic syndrome (HUS). The main agent of HUS is STEC, which produce a food borne disease at a low infective dose (<100 CFU/g). Cattle is a natural reservoir of STEC, and ground meat is a high-risk food since surface contamination is distributed throughout the meat. Tierra del Fuego (TDF) is part of the patagonian region of Argentina, which presents the highest rate of hemolytic uremic syndrome (HUS).Methods: In our study, all of the butcher shops in the island were sampled. Ninety-three samples of ground meat were taken from butcher shops enabled in three TDF communities. Samples were processed in accordance of the algorithm for STEC O157 and non-O157 STEC.Results: A total of 2.15% of the samples of ground meat from the retail outlets of TDF were suspected of O157: H7 non-STEC. STEC were absent in the sampling round.Conclusion: According to no one cases of HUS from TDF was reported at the National Vigilance System during our sampling period, we could not discard ground meat as the main source of STEC infection which cause HUS. Ground meat as infection source of STEC could not be discarded in TDF according to no report of HUS case was reported at National Vigilance System during to our sampling dates. Meat contamination could have a timely presentation coinciding with the cases of HUS. Also, other sources of infection could be involved locally. Prevention is a fundamental tool to use with HUS, it is necessary to implement various measures, including good manufacturing and hygiene practices, consumption and use of safe water at industry and home steps.

The recent experience of the Argentine competition authority Viecens, María Fernanda When the new government was elected at the end of 2015, the new members of the Argentine Competition Commission (Comisión Nacional de Defensa de la Competencia, CNDC) were appointed. At that moment, the CNDC was a disregarded and discredited agency, with almost 500 pending antitrust and merger cases and an average review timeframe of 30 months. Competition compliance was not an issue in the agenda of firms operating in Argentina (national firms in particular), which were more concerned about inefficiencies and delays in the performance of the agency, than about fines and remedies. The new administration announced its intention to activate competition policy and to strengthen the powers of the Argentine Competition Commission...

Empresas recuperadas y Estado local: El caso de Villa María (Provincia de Córdoba-Argentina) Barrera Calderon, Juan Emanuel Desde fines de la década del noventa, frente a la situación de quiebra, bajas en la productividad, adeudamiento de salarios, deudas fiscales y abandono por parte de las/os dueños, cobra visibilidad el fenómeno de recuperación de empresas. Lo que ha implicado la puesta en marcha de procesos de autogestión por parte de las/os trabajadores como alternativa a la desocupación. Luego de 2001 y hasta por lo menos 2015, la Economía Social (ES) se posicionó como un ámbito clave de las políticas públicas aplicadas por el gobierno nacional en su condición de población objetivo y como componente para la generación de empleo y la inclusión social. En ese marco, y en el interior de la provincia de Córdoba, República Argentina, la ciudad de Villa María contó con diversas experiencias de cooperativización y que, como dato diagnóstico, en principio parecían procesos similares a los que se daban en el resto del país. En este artículo intentaremos abordar la reconfiguración del Estado local en la cooperativización de tres empresas recuperadas prestadoras de servicios públicos en la ciudad de Villa María: la Cooperativa “Ctalamochita” Ltda., la Cooperativa “El Sol” Ltda. y la Cooperativa “7 de febrero” Ltda.; Since the end of the nineties, in the face of bankruptcy, low productivity, owed wages, tax debts and abandonment by the owners, visibility of the phenomenon of recovery of companies. What has involved the implementation of selfmanagement processes by workers as an alternative to unemployment. After 2001 until at least 2015, the Social Economy was positioned as a key area of public policies applied by the national government in its capacity as an objective population and as a component for generating employment and social inclusion. In this framework, and in the interior of the province of Córdoba, the city of Villa María had various experiences of cooperativization and, as a diagnostic data, in principle they seemed similar to those that occurred in the rest of the country. Thus, in this article we will try to address the reconfiguration of the local state in the cooperativization of three companies recovering public services in the city of Villa María: Cooperativa "Ctalamochita" Ltda., Cooperativa "El Sol" Ltda. Cooperativa "7 de febrero" Ltda.

Indigenous arbuscular mycorrhiza and Trichoderma from systems with soybean predominance can improve tomato growth Commatteo, Jacqueline Giselle; Consolo, Verónica Fabiana; Barbieri, Pablo Andres; Covacevich, Fernanda In the last decades, there has been a tendency towards sustainable agriculture. Following this trend, edaphic fungi as Trichoderma and arbuscular mycorrhizal fungi (AMF) could increase plant growth contributing to diminish agricultural chemical supply. However, little information exists in current research regarding the possible effects of alternative practices to soybean monoculture systems on fungal groups that could contribute to plant health and/or productivity. Thus, our objective was to assess changes in the abundance and diversity of indigenous AMF and Trichoderma from a long-term field experiment located in the Argentinean Pampas, in order to test the effect of alternative practices to soybean monoculture. The fungal ability to promote the growth of crops, such us tomato plant was also tested. Soil samples were collected from a soybean monoculture system (Sb), a system including cover crop (Avena sativa) followed by soybean (CC/Sb) and a system including rotations (rot) of Soybean-Maize-Wheat crops CC/Sb-rot, M-rot and W-rot, respectively. Highest AMF and Trichoderma abundance was found at W-rot and M-rot systems, and highest AMF diversity was found at W-rot and CC systems. Furthermore, highest mycorrhizal colonization was found at CC/Sb and W-rot systems. Inoculated plants with single AMF consortium or with Trichoderma strains showed significant increases in comparison with the control. Dual inoculation increased tomato plant growth as compared to the control, and evidence of synergism was found by increases in shoot and root growth. Our results show that dual inoculation with indigenous AMF and Trichoderma from alternative crop systems to soybean monoculture could play an important role in tomato plant growth. This information could be useful to decrease production costs and environmental impacts.

Parasites in a Holocene Environment: Their Presence on the Floor of Caves Amalfitano, Giorgina; Petrigh, Romina Sandra; Fugassa, Martín Horacio Exploratory examinations were performed in sediments of archaeological levels from Cerro Casa de Piedra, cave 7 (CCP7). The aim of the present study was to identify parasitic remains present in the floor where human occupation has been reported. Parasite remains of Eimeria macusaniensis, molineids and two capillariids nematodes were identified. A single oocyst of Eimeria ivitaensis was found, resulting in the first report from Patagonia. Parasites found in this work were previously reported in camelid coprolites. Parasitological findings showed camelids presence into the cave and a high contamination of domestic area. These findings reinforce the hypothesis about the role of caves in parasites circulation among mammals community of Patagonia.

Non-pollen palynomorphs notes: 3. Phototrophic loricate euglenoids in paleoecology and the effect of acetolysis on Trachelomonas loricae Shumilovskikh, Lyudmila S.; Schlütz, Frank; Lorenz, Maike; Tomaselli, María Belén Algal palynomorphs are useful indicators of freshwater environments in the past and present, allowing reconstruction of such environmental characteristics as former pH, trophic stage, temperature and salinity. However, the using of algal palynomorphs in paleoecology is restricted by their resistance to natural degradation and acetolysis treatment. In this study, we evaluate the usefulness of the loricate euglenophyte genera Trachelomonas and Strombomonas as paleoecological indicators. In order to evaluate their resistance to degradation, loricae morphology of four Trachelomonas species from the Culture Collection of Algae at Göttingen University (SAG) were studied with and without acetolysis treatment. The experiment demonstrates a strong dissolution under acetolysis of the three species T. hispida, T. lefévrei, T. zorensis and a reduction in the loricae length by T. similis. In the Holocene records, Trachelomonas can be found in non-acetolyzed samples, occurring together with other eutrophication indicators such as cyanobacteria and ciliate Codonella cratera. A review of recent algological literature supports Trachelomonas being a good indicator of organic pollution.

Inventar el imposible porvenir: estética y política; Inventing the impossible to come: esthetics and politics Chun, Sebastián ¿Qué es la invención? ¿Cuál es su relación con la tradición que viene a interrumpir? Estas preguntas guiarán el recorrido aquí propuesto, en el cual una concepción clásica de la invención, que acentúa su carácter novedoso y disruptivo, será puesta en cuestión. La reflexión sobre la vanguardia en Adorno y Horkheimer, la búsqueda de un poder destituyente por parte de Agamben y la concepción de la escritura desplegada por Borges nos servirán de preámbulos al análisis que realiza Derrida de la invención imposible. Este itinerario nos permitirá articular estética y política, en la búsqueda de un pensamiento emancipatorio que anuncie la invención de otro modo de lo político.; What is invention? What´s its relationship with the tradition which invention comes to interrupt? This questions will guide the itinerary we propose. Through its developement, the classic understanding of the invention, that points out its original and disruptive character, will be questioned. The consideration of the avant-garde of Adorno and Horkheimer, the seek on a destituent power of Agamben and Borges´ conception of writing will be the preamble to the analysis of the impossible invention made by Derrida. In this tour esthetics and politics may be articulated, in order to find an emancipatory thought which announces otherwise than politics.

Internet memes: una relación visual contemporánea; Internet memes: a contemporary visual relation Winckler, Greta El siguiente trabajo se propone pensar un tipo de imagen contemporánea: el meme. Como parte de nuestra economía visual actual, se da cuenta de su impacto y genealogía que se presenta no sólo como hilo histórico sino como necesaria para entender por qué los memes son tan eficaces y populares. Se propone pensar en particular a los memes políticos, anclados en la tradición de la sátira, planteando a estas imágenes “pobres” no como una emergencia totalmente nueva sino más bien desde una continuidad con artefactos visuales que las precedieron.; This article aims to think over a particular type of contemporary image: the Internet-meme. As a part of our visual economy, it is intended to expose its impact as well as its genealogy to understand why memes are so popular and efficient nowadays. This piece focuses on political memes, as belonging to a satirical tradition of images, implying that these so-called “poor” images are not a totally new phenomenon but, on the contrary, a continuity with preceding visual artifacts.

In silico analysis of an exercise-safe artificial pancreas with multistage model predictive control and insulin safety system García Tirado, José Fernando; Colmegna, Patricio Hernán; Corbett, John P.; Ozaslan, Basak; Breton, Marc D. Background: Maintaining glycemic equilibrium can be challenging for people living with type 1 diabetes (T1D) as many factors (eg, length, type, duration, insulin on board, stress, and training) will impact the metabolic changes triggered by physical activity potentially leading to both hypoglycemia and hyperglycemia. Therefore, and despite the noted health benefits, many individuals with T1D do not exercise as much as their healthy peers. While technology advances have improved glucose control during and immediately after exercise, it remains one of the key limitations of artificial pancreas (AP) systems, largely because stopping insulin at the onset of exercise may not be enough to prevent impending, exercise-induced hypoglycemia. Methods: A hybrid AP algorithm with subject-specific exercise behavior recognition and anticipatory action is designed to prevent hypoglycemic events during and after moderate-intensity exercise. Our approach relies on a number of key innovations, namely, an activity informed premeal bolus calculator, personalized exercise pattern recognition, and a multistage model predictive control (MS-MPC) strategy that can transition between reactive and anticipatory modes. This AP design was evaluated on 100 in silico subjects from the most up-to-date FDA-accepted UVA/Padova metabolic simulator, emulating an outpatient clinical trial setting. Results with a baseline controller, a regular MPC (rMPC), are also included for comparison purposes. Results: In silico experiments reveal that the proposed MS-MPC strategy markedly reduces the number of exercise-related hypoglycemic events (8 vs 68). Conclusion: An anticipatory mode for insulin administration of a monohormonal AP controller reduces the occurrence of hypoglycemia during moderate-intensity exercise.

La ciudad y los sentidos: las sensaciones como imágenes del espacio y de las afecciones en el cine argentino contemporáneo; The city and the senses: sensations as images of space and affections in Argentine contemporary cinema Dipaola, Esteban Marcos INDEX: Scielo; Latindex; DOAJLas relaciones cine y ciudad son constitutivas, porque el cine surge como experiencia urbana.El cine contemporáneo se constituye desde la dimensión de una imagen-espacio. De acuerdo a la división efectuada por G. Deleuze, el cine clásico se constituía desde la imagen-movimiento y el cine moderno desde la imagen-tiempo; pero la contemporaneidad expresa las imágenes de la espacialidad en el cine. En este artículo se analizan películas recientes del cine argentino, que permiten una reflexión desde las imágenes sobre las sensaciones del recorrido urbano. En el abordaje aparece la noche, el verano y el calor como modos de circulación de la ciudad de Buenos Aires, pero exponiendo con ello la posibilidad de una comprensión de las imágenes de lo urbano mediante las sensaciones que atraviesan los tránsitos: el agobio, la humedad, los vapores y olores y las memorias fantasmáticas de encuentros y desencuentros que constituyen una ciudad.; The relationship between cinema and city are interrelated because film arises as an urban experience. According to the division elaborated by Gilles Deleuze, classic cinema is conceived from an image-movement perspective whereas modern cinema from an image-temporal aspect. However contemporary films are founded in a dimension between image and space. This article analyzes recent films from Argentine cinema that allow the contemplation of images that inhabit an urban sensation. Throughout the analysis, elements like the night, the summer and the heat show the audience the circulation of the city of Buenos Aires while at the same time exhibit a possible understanding of urban images through the sensations that cross everyday transit: the suffocation, the humidity, the vapors, the smells and the phantasmagoric memories of encounters and separations that all constitute a city.

Uso de magnetometría terrestre en la exploración de pelitas ferruginosas en canteras del Distrito minero Barker, provincia de Buenos Aires; Use of terrestrial magnetometry in the exploration of ferruginous pelites in quarries of the Barker mining district, province of Buenos Aires Tessone, Mario Osvaldo Rafael; Nigro, Joaquín; Perdomo, Santiago; Etcheverry, Ricardo Oscar; Fernandez, Raul Roberto; Tessono, Nicolás; Caballe, Marcelo Fernando En la Sierra de La Juanitay la Cuchilla de las Águilas, cercanas a lalocalidad de Barker, se extraen  rocasferruginosas destinadas a la industria del cemento.  La falta de continuidad lateral de los bancosconstituye un problema para los productores, tanto en la planificación de la explotación como de la recuperación ambiental. Con el fin de contribuir a la solución o mitigar esta problemática se aplicaron técnicas geofísicas y a partir de ello serealizaron reinterpretaciones geológicas de las áreas. Sobre la base de la información de superficie se planteó la utilización de un método geofísico rápido y de bajo costo, consistente en medicionesde susceptibilidad magnética en las rocas decanteras seleccionadas. Comprobada la respuesta positiva de los niveles ferríferos por sus valoreselevados de susceptibilidad, se programó una exploración magnetométrica terreste en el área de influencia de las canteras, con el fin deevaluar su eficacia para detectar en el subsuelo capas con altos tenores deHierro y ajustar el tratamiento de los datos para la obtención de resultados óptimos.; Ferruginous pelites mainly destined for the cement industry are extracted in the Sierra de La Juanita and Cuchilla de lasÁguilas, near Barker town. The lack of lateral continuity of the pelitic banks constitutes a problem for the producers, both in the planning of the exploitation and of the related environmental recovery. In order to contribute to the solution or mitigate this problem, geophysical techniques were applied, which allowed geological reinterpretations to be done. Based on surface information, the use of a fast and low-cost geophysical method was proposed. The latter consisted of magnetic susceptibility measurements in selected quarry rocks. Once the positive response of the ferriferous levels was verified due to their high susceptibility values, a terrestrial magnetometric exploration in the quarries influence areas was programmed, in order to evaluate its effectiveness to detect underground layers with high iron levels and adjust data processing for optimal results.

Republicanismo participativo: Bases y puntos de partida para un modelo democrático constitucional situado; Participatory Republicanism bases and starting points for a constitutional democratic model located Olivares, Nicolàs Emanuel Recientemente el filósofo chileno F. Muñoz León ha formulado severas críticas al modelo democrático libertario predominante en diversos países de Sudamérica. Su propuesta teórica tiene por meta la construcción de un ethos e institucionalidad política que resulta consistente con una democracia republicana sustentada en la idea de libertad como no dominación. Sin embargo, su republicanismo se distancia notoriamente de la versión defendida por el filósofo irlandés P. Pettit, en tres aspectos fundamentales, ya que F. Muñoz León objeta el carácter individualista de la noción de sujeto político; considera inapropiado la desconexión del plano político y el económico social; y afirma que la obtención de genuinos consensos políticos requiere modificar profundamente los diseños institucionales liberales vigentes. Atendiendo a dichas objeciones, es que en este trabajo brindaremos argumentos en defensa de un republicanismo participativo, el cual promueve la interacción entre sujetos políticos colectivos; imbrica los aspectos político y social; y explicita un diseño institucional diferente al liberal.
