The Russian and Argentinian experiences of radical reform: between economy and politics Heredia, Mariana Laura; Kirtchik, Olessia The 1970s and 80s saw a wave of market liberalization in Latin America, Africa, and Asia, but also in the United States and Western Europe, reaching Central and Eastern Europe by the end of the 1980s. Existing studies tend to focus on the decision-makers and adopt a monolithic view of reform implementation. To account for complexity, we study the cases of Argentina and the USSR/Russia from tentative market liberalization in the 1970s until the crisis of neoliberalism in the late 20th and early 21st century. After brief observations on the history of economic reform in each country, we consider the preconditions of reforms and the delegation of decision-making to economists; the institutional context and, in particular, tensions between political democratization and economic liberalization; and the unequal influence of neoliberal ideas within Russian and Argentinean institutions. Finally, we assess whether the neoliberal order remained intact after the crises of 1998 and 2001. In English, extensive summary in Russian.

Comparing post-soviet and Latin American societies: from “transition” to “transformation" Heredia, Mariana Laura; Kazakova, Olessia Introduction to a thematic issue entitled “Russia/former USSR/Latin America: Studies in Post-Authoritarian Transformation.” Because of language barriers and a lack of institutionalized ties, the impressive literature on democratization in each of these areas is virtually unknown to authors from the other region. The striking similarities between the former Soviet Union and Latin America are best studied through comparison based on ground-level fieldwork. This approach highlights the blind spots of standard democratization and free-market modernization theory, which tends to universalize scenarios of economic development without paying sufficient attention to case studies. The introduction outlines the conceptual shift from “transition” to “transformation” in the literature on democratization, and presents the articles in the issue as well as some of the challenges the editors faced in bringing authors from Latin America and the former USSR together. English and Russian versions.

La sinergia en la producción de la información ambiental Coria, Lorena Gabriela La cuestión ambiental enfrenta desafíos que ponen en juego un conjunto de actores que participan directa o indirectamente en el marco de la configuración de las situaciones ambientales con distinto grado de riesgo y manifestación en las escalas territoriales. Encontramos así, actores que por acción u omisión generan consecuencias ambientales y otros que las sufren. Por otro lado, desde el plano de la producción del conocimiento, continúa el debate sobre las implicancias terminológicas vinculadas a algunos conceptos claves sobre los cuales se estructuran la cuestión ambiental.

Populismo, regeneracionismo y democracia Aboy Carles, Gerardo Este trabajo desarrolla un diálogo crítico con la interpretación de Ernesto Laclau sobre la teoría de la hegemonía y su conceptualización del populismo. En primer lugar, se demuestra como la impureza que caracteriza a las lógicas de la hegemonía nos llevan a concebir a las identidades políticas como solidaridades híbridas, de fronteras superpuestas, alejadas de la imagen laclausiana de formaciones excluyentes. Los populismos clásicos latinoamericanos han constituido un mecanismo particular, entre otros posibles, de resolver las tensiones entre la representación de una parte y la representación de la comunidad en su conjunto. La identificación entre política y populismo realizada por Laclau resulta entonces problemática. En consecuencia, el populismo no puede ser reducido a una dicotomización antagónica de la comunidad, y, la regeneración de los actores pasará a ocupar un lugar central en la caracterización del fenómeno.; This work develops a critical dialog with Ernesto Laclau's theory of hegemony and his conceptualization of populism. Firstly, it argues that the impurity that characterizes the logics of hegemony leads us to conceiving political identities as hybrid solidarities, of superposed borders. This is a different image from Laclau's exclusive identities. Classic Latin-American populisms have constituted a particular mechanism, among others, of solving the tensions between the representation of a part and the representation of the whole community. Laclau's identification between politics and populism becomes problematic. Consequently, populism cannot be reduced to an antagonistic dichotomization of the community. The regeneration of the actors involved in a populist practice will thus occupy a central place in the characterization of this political phenomenon.

Effect of post-weld heat treatment on the wear resistance of hardfacing martensitic steel deposits Gualco, Agustín; Svoboda, Hernán Gabriel; Surian, Estela Silvia; de Vedia, Luis Alberto The effect of different post-weld heat treatments on the microstructure and wear resistance of martensitic deposits were studied. The deposit was welded using a metal-cored tubular wire, in the flat welding position, on a 375 × 75 × 19mm SAE 1010 plate, using 98% Ar-2% CO2 shielding gas mixture and with an average heat input of 2.8 kJ/mm. The samples were heat treated at temperatures between 500 and 6808C for 2 h. Chemical composition, Vicker's microhardness and wear properties with AMSLER tests in a sliding condition were determined. In the as welded condition, the microstructure was principally composed of martensite and retained austenite. Significant variations in wear resistance and hardness were measured for different tempering temperatures. For the different heat-treated conditions, it was observed that the decomposition of retained austenite to martensite and carbide precipitation was associated with the tempering of martensite. A secondary hardness effect was detected with maximum hardness of 710HV for 550°C heat treatment temperature. The best performance in wear test was obtained for this condition. Wear rates for the different conditions were obtained and mathematical expressions were developed. For each case, wear mechanisms were analyzed.

Control de Robots Móviles con Incertidumbres Dinámicas usando Redes de Base Radial Rossomando, Francisco Guido; Soria, Carlos Miguel; Carelli Albarracin, Ricardo Oscar En este trabajo se presenta un control de seguimiento de trayectorias de robots móviles. La estructura de control propuesta combina un modelo de linealización por realimentación basado en el modelo cinemático nominal, y una red neuronal directa para el control dinámico adaptable. La dinámica del robot es aprendida por una red neuronal basadas en funciones de base radial (RN-FBR) en un circuito de realimentación adaptable, ajustando el peso y las funciones de base radial. Se muestra un análisis de estabilidad del sistema de neuro-control adaptable. Se comprueba que los errores de control están limitados en función de la aproximación de error de la RN-FBR, la cual se comprueba con resultados experimentales.

Estudio observacional naturalistico sobre la efectividad del tratamiento farmacológico en una cohorte de pacientes con demencia tipo Alzheimer; Naturalist observational study on effectiveness of drug treatment of a cohort of patients with Alzheimer type dementia Rojas, Galeno; Bartoloni, Leonardo Carlos; Serrano, Cecilia Mariela; Dillon, Carol; Allegri, Ricardo Francisco Introduction: Naturalistic studies in clinical practice present great utility to guide the decision making and allow to corroborate the experimental findings of clinical trials. In Argentine, there are not published data of this type of studies in Alzheimer's Disease (DTA) with cholinesterase inhibitors. Objective: To evaluate effectiveness of treatment with donepezil patients with DTA mild degree in clinical practice. Materials and methods: Observational study, not controlled and longitudinal of 24 weeks of follow up in the Laboratory of Memory of the Zubizarreta Hospital. Were selected patients treated with donepezil with diagnosis of probable or possible mild DTA according to DSM IV and NINCDS-ADRDA criteria. The global, cognitive and behavioural domains were evaluated and Caregiver Burden. Results: Were selected for the analysis 38 patients whose completed the follow up, They were 63,15% (n=24) probable DTA and 36,84% (n=14) DTA with vascular component. At the end of the follow up a significant change in memory, visuespacial skills and language was demonstrated. Significance in global, behavioural and Caregiver Burden was not demonstrated nor activities of daily life. A 10% presented improvement of 2 points in MMSE (50% stayed stable, 39% deteriorated) to the 6 months. The parkinsonism risk was duplicated at the end of the study. Conclusion: In this work, a smaller group of patients with mild DTA responded favorably to donepezil in cognitive domain.Half of the patients stayed stable in their MMSE.

Integrable systems and Poisson-Lie T-duality: A finite dimensional example Capriotti, Santiago; Montani, Hugo Santos We study the deep connection between integrable models and Poisson-Lie T-duality working on a finite dimensional example constructed on SL(2,C) and its Iwasawa factors SU(2) and B. We shown the way in which the Adler-Kostant-Symes theory and collective dynamics combine to solve the equivalent systems by solving the factorization problem of an exponential curve in SL(2,C). It is shown that the Toda system embraces the dynamics of the systems on SU(2) and B.

Proteomic profile regulated by the anticancer peptide CIGB-300 in non-small cell lung cancer (NSCLC) cells Rodríguez Ulloa, Arielis; Ramos, Yassel; Gil, Jeovanis; Perera, Yasser; Castellanos Serra, Lila; García, Yairet; Betancourt, Lázaro; Besada, Vladimir; González, Luis J.; Fernández De Cossio, Jorge; Sanchez, Aniel; Serrano, Joem M.; Farina, Hernán Gabriel; Alonso, Daniel Fernando; Acevedo, Boris E.; Padrón, Gabriel; Musacchio, Alexis; Perea, Silvio E. CIGB-300 is a proapoptotic peptide-based drug that abrogates the CK2-mediated phosphorylation. This peptide has antineoplastic effect on lung cancer cells in vitro and in vivo. To understand the mechanisms involved on such anticancer activity, the NCI-H125 cell line proteomic profile after short-term incubation (45 min) with CIGB-300 was investigated. As determined by 2-DE or 2D-LC-MS/MS, 137 proteins changed their abundances more than 2-fold in response to the CIGB-300 treatment. The expression levels of proteins related to ribosome biogenesis, metastasis, cell survival and proliferation, apoptosis, and drug resistance were significantly modulated by the presence of CIGB-300. The protein translation process was the most affected (23% of the identified proteins). From the proteome analysis of the NCI-H125 cell line, novel potentialities for CIGB-300 as anticancer agent were evidenced.

Changes in topsoil bulk density after grazing crop residues under no-till farming Fernández, Patricia Lilia; Alvarez, Carina Rosa; Schindler, Valeria; Taboada, Miguel Angel The grazing of crop residues during the winter in integrated crop-livestock systems can either increase soil bulk density (BD) by compaction or decrease BD by swelling, as a function of gravimetric soil water content (GW) during grazing. A field experiment was conducted from 2005 to 2008 to evaluate the BD response to grazing in a no-till silty loam soil (Typic Argiudoll) of the Pampas region of Argentina. Soil BD (core method), GW data and the calculated air volume (AV) were obtained from the 0-50mm and 50-100mm layers at different sampling times from ungrazed and grazed treatments. Over most of the study period (2006 through 2008) soil BD showed little impact from grazing, with minimal temporal variation (1.32-1.46Mgm-3). This stable behavior was ascribed to low rainfall and relatively low GW values at the time when soil was trampled by livestock and routinely trafficked by machinery. Soil BD in the upper (0-50mm) layer was significantly (p<0.001) lower at the beginning of the study (2005 to early 2006), when the rainfall was higher (as was soil GW) during transit periods. Lower BD was not due to soil swelling but to air that was trapped by kneading in response to transit of livestock and machinery. Fitted straight lines indicated that this process became particularly prominent when GW was >330gkg-1 in the ungrazed treatment and GW was >240gkg-1 in the grazed treatments. Grazing accentuated the soil kneading process that promoted air entrapment. Our results suggest in this no-tilled silt loam soil that winter grazing of crop residues caused no deterioration of topsoil porosity in the no-tilled silty loam soil.

La sexualidad en la red de los discursos mediáticos: Una lectura de la construcción de la educación sexual en la prensa argentina Boccardi, Facundo Gustavo La implementación de la educación sexual en las escuelas emerge como tema de la agenda mediática de la prensa argentina a comienzos del 2004. En este artículo, se recurre a los aportes teóricos de Michel Foucault y Judith Butler sobre la sexualidad para abordar los procedimientos discursivos de la prensa argentina en la construcción de la educación sexual como objeto.; The implementation of sex education in schools comes out as a topic for the media agenda of the press in Argentina in early 2004. In this paper, we use the theoretical contributions of Michel Foucault and Judith Butler on sexuality to address the discursive procedures of the press in Argentina in the construction of sex education as an object.

Experimental investigations on flashing-induced instabilities in one and two-parallel channels: A comparative study Marcel, Christian Pablo; Rohde, Martin; Van Der Hagen, Tim H. J. J. In this investigation, experiments conducted in a natural circulation test facility at low power and low pressure conditions, in the one single and two-parallel channels configuration are presented and discussed in detail. The novel manner of visualizing the results allowed characterizing the facility at any time and position which helped to thoroughly understand the instability mechanisms. Different modes were observed for each configuration. In the case of having two-parallel channels, four different behaviors have been observed: stable flow circulation, periodic high subcooling oscillations, a-periodical oscillations and out-of-phase periodical oscillations. In addition, stability maps were constructed in order to clarify the region in which each mode is dominant. The results obtained from both the one and two-parallel channels configurations are thus analyzed and compared. As a result, some similarities have been observed between the intermittent flow oscillations found in the single channel experiments and the high subcooling oscillations found in the two-parallel channels experiments. Moreover, similarities have also been found between the sinusoidal flow oscillations existing in the single channel experiments and the out-of-phase oscillations from the two-parallel channels experiments. The experiments presented in this work can be used to benchmark numerical codes and modeling techniques developed to study the start-up of natural circulation BWRs.

Infraestructura Ferroviaria y Ciudad. Modalidades urbanísticas de resolución de sus vínculos en la historia urbana de Santa Fe. Saus, María Alejandra Interpretaciones recientes abonan matices locales en la apropiación de ideas sobre la ciudad. Por ello es posible afirmar que el urbanismo en Argentina se constituyó por sucesivas mutaciones, delineándose como disciplina autónoma alrededor de 1910. A partir de entonces se perfiló una tradición unitaria, a pesar de los variados nombres que recibió durante el siglo XX. Tales denominaciones manifiestan modos de legitimación de una disciplina que se nutrió de los saberes de diversas ciencias. Sin embargo, las coyunturas históricas establecen quiebres epistemológicos, siendo un indicador de los mismos el abordaje de la inserción ferroviaria en la ciudad. Si el siglo XIX abrazó al ferrocarril como sinónimo de progreso, el urbanismo segregó las infraestructuras para liberar a la ciudad de un obstáculo. Recientemente, la reconversión de áreas ferroviarias por su valor cultural e histórico, vuelve a revelar cómo estas prácticas resuelven en idiomas diversos el diálogo histórico entre infraestructura y ciudad.

An Improved Control Strategy for Hybrid Wind Farms Leon, Enrique Andres; Mauricio, Juan Manuel; Gomez-Exposito, Antonio; Solsona, Jorge Alberto This paper addresses the control requirements of hybrid wind farms, comprising a relatively large number of conventional Induction Machines (IM) along with one or very few Permanent Magnet Synchronous Machines (PMSM), capable of compensating the reactive power demanded by the IMs during faulty conditions as well as attenuating the active power variations due to wind gusts. Based on the superposition theorem and the feedback linearization technique, a controller is designed to independently regulate the positive and negative sequence currents of the PMSM Voltage Source Converters (VSC), overcoming several drawbacks of existing approaches in the presence of unbalanced voltages. In the proposed scheme, the grid-side VSC currents are controlled in order to improve the ride-through capability of IMs, so that the whole wind farm can fulfill demanding grid codes in absence of extra equipment, such as STATCOMs. As shownby the test results, combining IM-based wind farms with PMSMs accomplishes several relevant goals: delivering the reactive power consumption of the IMs, increasing the rated active power of the installation and smoothing mechanical power oscillations.

El Plan del 80 en Santa Fe: regionalización tardía ante la suburbanización inminente Rausch, Gisela Ariana Se intenta una aproximación al Plan Urbano de 1980 de la ciudad de Santa Fe, el cual puede ubicarse dentro de la serie de planes con voluntad de regionalización, que tuvieron lugar en parte de Argentina entre las décadas del 40 y el 60. De publicación tardía, durante el gobierno de facto de 1976-1983, el Plan se alineaba con lo que se dio en llamar planificación integral. El abordaje del Plan tiene como objetivo principal volver la mirada hacia una herramienta de actuación urbana en la que por primera vez en la historia urbanística local se menciona la ocupación de las áreas periféricas de la ciudad. Cuestión que en los últimos años, frente el desborde suburbano que muchas ciudades intermedias argentinas han sufrido a partir de los 70, y en particular, frente al problema hídrico recurrente en Santa Fe, por la ocupación del valle del Paraná, continúa en mesa de debate.

Dieta de Lontra longicaudis (Carnivora, Mustelidae) en el Parque Nacional El Rey (Salta, Argentina) y su comparación con otras poblaciones de la cuenca del Paraná Chemes, Silvina Beatriz; Giraudo, Alejandro Raul; Gil Carbó, Guillermo Se analizó la dieta de Lontra longicaudis en el Parque Nacional El Rey, en la eco-región de las Yungas, noroeste argentino. Se compararon estos datos con los de poblaciones previamente estudiadas en la laguna Iberá (Esteros del Iberá) y en el río Iguazú (Selva paranaense) en el nordeste argentino. Se analizaron 130 heces colectadas en 37 sitios evaluando porcentaje de ocurrencia, frecuencia relativa, importancia relativa porcentual y diversidad de Levins. Se comparó con otras poblaciones mediante el índice de similitud porcentual, re-muestreo por bootstrap y análisis no paramétricos. De un total de 623 presas, Peces, Insectos y Crustáceos fueron más frecuentes que Anfibios, Moluscos, Reptiles y Mamíferos. La mayoría de las presas fueron organismos bentónicos. Nuestros resultados fueron más similares a uno de los estudios del Iberá. Otros dos estudios, del Iberá y del Iguazú, publicados por el mismo autor, fueron más semejantes entre sí. La adaptabilidad trófica de L. longicaudis a diferencias en disponibilidad y variación temporal de las presas o los sesgos metodológicos entre autores, podrían ser causas de las diferencias en las dietas de las poblaciones estudiadas en la cuenca del Paraná.

Orthogonally additive holomorphic functions of bounded type over C(K) Carando, Daniel Germán; Lassalle, Silvia Beatriz; Zalduendo, Ignacio Martin It is known that all k-homogeneous orthogonally additive polynomials P over C(K) are of the form P(x)= ∫Kxkdμ. Thus, x → xk factors all orthogonally additive polynomials through some linear form μ. We show that no such linearization is possible without homogeneity. However, we also show that every orthogonally additive holomorphic function of bounded type f over C(K) is of the form f(x)=∫Kh(x)dμ for some μ and holomorphic h : C (K) → L1(μ) of bounded type.

Chemoprophylactic activity of flubendazole in cystic echinococcosis Ceballos, Laura; Elissondo, María Celina; Sanchez Bruni, Sergio Fabian; Confalonieri, Alejandra; Denegri, Guillermo Maria; Alvarez, Luis Ignacio; Lanusse, Carlos Edmundo Background: Cystic echinococcosis (CE) is an important public health problem worldwide. Flubendazole, administered in tablets, has shown poor in vivo efficacy against CE in humans. However, flubendazole prepared as a solution caused a marked reduction in hydatid cysts developed in mice. The goal of the current work was to compare the chemoprophylactic effect of flubendazole formulated either as a hydroxypropyl-β-cyclodextrin solution or as a carboxymethylcellulose suspension in secondary CE in mice. Methods: Balb/C mice were infected with Echinococcus granulosus protoscoleces. One day after infection, the animals were allocated into 3 different experimental groups: unmedicated control and treated at the time point of infection with flubendazole either prepared as a solution or suspension given twice a day during 15 days. Six months after infection, the animals were sacrificed to collect and weight parasitic cysts. Cyst samples recovered from infected mice of each experimental group were prepared for both scanning and transmission electron microscopy. Results: Both flubendazole formul tions induced a significant reduction in cyst weight compared to the cysts recovered from the unmedicated control animals. Both formulations showed similar flubendazole-induced ultrastructural morphological changes. Conclusion: Flubendazole offers a great potential to become a drug of choice in the preventive treatment of cystic echinococcosis.

Total ozone and equatorial zonal wind Zossi Artigas, Marta Maria; Fernandez de Campra, Patricia Spatial correlations between total column ozone observed by TOMS and equatorial zonal winds from 1979 to 2003 have been assessed. Four months and three different altitude levels have been analyzed: January and July (solstice months), April and October (equinoctial months), and 10, 30 and 50. hPa. The results are different for the months and altitudes considered. The highest correlations values appear in tropical zone at 30. hPa. The Brewer-Dobson circulation plays a key role in regulating the abundance of ozone, influenced by the quasi-biennial oscillation (QBO) circulation. Since the Brewer-Dobson is a slow circulation, correlations considering lags between one and 12 months were estimated. In this case, the highest correlations values are moving to subtropical latitudes at winter hemisphere, with different behaviors for three altitude levels considered.

Entomofauna asociada a garbanzo en el noroeste de Córdoba (Argentina); Entomofauna associated to chickpea in northwest of Cordoba (Argentina) Avalos, S.; Mazzuferi, V.; Fichetti, P.; Berta, Dominga Carolina; Carreras, J El garbanzo es un cultivo que se desarrolla en invierno. Entre los factores bióticos que limitan su producción se señalan a los insectos. El objetivo de este trabajo fue determinar las especies y abundancia de insectos fitófagos y sus enemigos naturales, asociados a dos cultivares de garbanzo (Chañaritos S156 y Norteño) en el noroeste de Córdoba. Durante 2006-2007, desde julio a noviembre se recolectaron manualmente los insectos presentes en sus diferentes estados de desarrollo en 30 plantas de cada cultivar tomadas al azar, y hojas con síntomas de moscas minadoras. A partir de la cría de insectos fitófagos se obtuvieron parasitoides. Se determinaron 15 especies de fitófagos y nueve de enemigos naturales. Las comunidades de insectos en ambas cultivares se hallaron dominadas por Lepidoptera, siendo Heliothis virescens la especie más abundante. Se registraron cinco especies de áfidos (Hemiptera) destacándose por su abundancia Acyrtosiphon pisum, cuatro especies de Thysanoptera que constituyen la primera cita sobre garbanzo y Liriomyza sp. (Diptera: Agromyzidae) en hojas minadas. Entre los predadores se encontraron Coccinellidae (Coleoptera) y Reduviidae (Hemiptera). Los parasitoides Hymenoptera Ichneumonidae y Chalcididae emergieron de H. virescens; Braconidae de áfidos; Eulophidae de Liriomyza sp. y Scelionidae de huevos de chinches. Por la etapa del cultivo en que se encuentra, daño directo y abundancia H. virescens sería la especie más perjudicial en la zona de estudio. Deben profundizarse las investigaciones referentes al rol como plagas potenciales de las principales especies de fitófagos y la incidencia de sus controladores naturales.; The chickpea is a crop that grows in winter. Among the biotic factors that limit the production are the insects. The aim of this work was to determine the species and abundance of insect herbivores and its associated natural enemies to cultivars of chickpea (Chañaritos S156 and Norteño) in the northwest of Cordoba. During 2006-2007, from July to November, insects in different states of development were collected manually in thirty plants of each cultivar that were chosen, as well as leave with symptoms of leafminers. From the breading of insect herbivores, specimens of parasitoids were obtained. Fifteen species of herbivores and nine of natural enemies associated to them were determined. The communities of insects in both cultivars were dominated by Lepidoptera, being Heliothis virescens the most abundant species. Five species of aphids (Hemiptera) were collected and Acyrtosiphon pisum was the most abundant, four registered species of Thysanoptera constitute the first appointment on the chickpea and Liriomyza sp. (Diptera: Agromyzidae) in leaves mined. The predators were Coccinellidae (Coleoptera) and Reduviidae (Hemiptera). Parasitoids Hymenoptera: Ichneumonidae and Chalcididae emerged from H. virescens; Braconidae of aphids; Eulophidae of Liriomyza sp. and Scelionidae of eggs of bugs. Because the stage of the crop in which they are, direct damage and abundance H. virescens could be the most detrimental species in the zone of study. The research of the role of the potential pests of the main phytophagous insect species and the incidence of their natural enemies should be developed.
