    Full Text Available In this paper we address two important issues for the young pension fund industry in Argentina: (i How can individual funds be ranked according to their efficiency? and (ii How have recent regulations -mainly, limiting the use of promotion for transferring members and allocating residual members not according to market shares but evenly among the funds- influenced costs? Panel data are used to estimate a cost frontier and relative efficiency is defined accordingly as the distance between firms' actual costs and the frontier. We find that regulation has increased total costs but has not modified relative efficiency to a significant extent.

    International Nuclear Information System (INIS)

    The history of Argentina nuclear development can be summarized into two periods: 'splendour' and 'stand-by'. The former starting in the decade of the 1950s until the late 1970s while the latter period goes from the late 1970s to 2006. The first period (1950-1980) was characterized by a national policy of scientific and technological development; State intervention in the area of industrial production. The military aspects, if any, were marginal in the context of the overall development. During this period, important public scientific technological projects were carried out: the production and sale of experimental reactors, nuclear plants (Atucha I and Embalse), and some projects aimed to developing national industry. The stimulus experienced in the country in this period accompanied the role of nuclear technology worldwide due to the Cold War and the persuasion factor among the main powers. However, during the 1970s and 1980s the whole world started questioning these technologies which ran parallel to the liberalization of the countries economies. The second period (1980s onwards) was characterized by many economic problems and the consequent transitory stop of national nuclear projects; e.g. Argentina transitory stopped its third nuclear plant (at present under construction). At that moment, neoliberal politics were aimed at reducing the role of the State and promoting privatization, separating nuclear projects from governmental control, trying to privatize the nuclear plants, and cutting scientific budgets. Argentina has two nuclear power plants in operation providing 8.6% of the total country's electricity. A third one, 692 MW(e) power reactor PHWR Atucha-2 construction was stopped in the 1990s and re-started in 2007 it is expected to be in commercial operation by 2011). Argentina nuclear power plants utility, NA S.A. is preparing the refurbishment of its CANDU-6 reactor. Argentina Atomic Energy Commission (CNEA) has a prototype of its CAREM nuclear power plant

    Background notes on Argentina provide a profile of the geography, selected demographic features, government and economic conditions. Descriptive text includes a discussion of the people, their history and political conditions, the government and officials, the state of the economy, their defense, foreign relations, and relations with the US. The 1992 estimated population was about 33 million of whom 97% are European (mostly Spanish and Italian). Religions represented are Roman Catholic (92%), Protestant (2%), Jewish (2%), and other (4%). Adult literacy is 95%. 36% are engaged in industry and commerce, 20% in services, 19% in agriculture, 6% in transport and communications, and 19% other. Per capita gross domestic product was $4,500. There are only 50,000 native Indians remaining in peripheral provinces. The population enjoys a high standard of living and a low growth rate. The country was shaped by dominant forces: modern agricultural techniques and the integration of the country into the world economy. Foreign investment aided the economic revolution. Conservative and radical rule has swung the country back and forth politically since 1916. Colonel Juan Domingo Peron led a successful military coup in 1943 and was elected in 1946. Policies were instituted to give a greater voice to the working class, and with the influences of his wife, women's groups. In 1955, he was ousted by the military, which failed to revive the economy and quiet increasing terrorism. After a number of difficult elections, Peron was reinstated as president in 1973. Extremists on the left and right threatened public order; the military as a consequence imprisoned persons indefinitely. Peron's wife succeeded him after his death, but was removed from office in the military coup of 1976. Basic human rights were violated during this period. By 1983, a fair election was held and support increased for a democratic system. In 1989, Carlos Saul Menem, a Peronist candidate, won and established

    Full Text Available En este trabajo se analizan las bases sobre las que se está desarrollando el proceso de transición hacia la TV digital en Brasil y Argentina, y se discuten las posibilidades que la transición presenta para replantear la estructura de mercado y el modelo de regulación de la TV abierta en los países del Mercosur. La principal hipótesis es que la TV digital abre una oportunidad única para reformar el actual modelo de radiodifusión basado en la concesión de un número reducido de licencias a operadores de tipo generalista. Al multiplicar la capacidad de transmisión y facilitar el desarrollo de servicios interactivos tanto de entretenimiento como educativos y de información, la transición a la TV digital se ofrece como instrumento de política pública para alcanzar objetivos clave en materia de comunicación, como el pluralismo, la apertura del mercado y el achicamiento de la llamada brecha digital.

    Full Text Available La zona central de la Patagonia, Argentina, se encuentra sometida a explotación petrolera y sus suelos se caracterizan por ser deficientes en nitrógeno. Esto causaría un efecto negativo en los procesos de atenuación natural que se desarrollan en los suelos contaminados con hidrocarburos. El objeto de este estudio fue determinar cual es el efecto de la deficiencia de nitrógeno sobre la biodegradación de los hidrocarburos en un suelo de la Patagonia, Argentina. Se trabajó con tres microcosmos a los que se les realizó tratamientos diferentes. En uno se monitoreo la atenuación natural del sistema, en otro la fertilización con nitrógeno (N, fósforo (P y potasio (K, y en el último la fertilización con P y K. Durante el seguimiento se determinaron mineralización y medición de hidrocarburos, y se realizaron recuentos bacterianos y determinación de nitrato, nitrito y amonio. Los resultados indican que es posible la biodegradación de hidrocarburos en el suelo deficiente de nitrógeno de la Patagonia estudiado en tiempos mas prolongados que en aquellos que se realiza una fertilización con nitrógeno. El nitrógeno necesario para el proceso sería obtenido por los microorganismos del suelo por fijación biológica.

    Full Text Available Se describe un modelo experimental para el estudio de la artritis en equinos que consistió en la aplicación intracarpal de 0.01 mg/kg de lipopolisacáridos (LPS. Se aplicó un diseño experimental de cross-over con dos períodos. Los parámetros clínicos comparados entre los grupos tratado y control incluyeron temperatura corporal, largo de paso, circunferencia carpiana, ángulo carpiano en reposo y ángulo carpiano en flexión. Diferencias estadísticamente significativas entre los grupos tratado con LPS y control fueron evidentes entre 1 y 48 h post-inyección en la temperatura corporal y entre las 2 y 48 h en el largo de paso y el ángulo carpiano en flexión. Modificaciones más tardías fueron observadas en la circunferencia carpiana y en el ángulo carpiano en reposo, entre las 4 y 48 h y entre las 8 y 24 h post-administración de LPS, respectivamente. El ángulo carpiano en reposo fue el único parámetro que retornó a los valores basales al final de la experiencia; sin embargo, los animales no mostraron secuelas del experimento transcurridas 72 h. El presente modelo no afectó en forma importante el bienestar animal y sería útil para el estudio de drogas antiartríticas. An experimental model for studying arthritis in horses, consisting on intracarpal administration of LPS at a dose rate of 0.01 µg/kg, is described. A two-ways cross over design was applied. Evaluated clinical end-points on LPS-treated and control groups were body temperature, stride length, carpal circumference, rest angle flexion and maximal carpal flexion. Statistically significant differences between LPS-treated and control groups were observed between 1 and 48 h post-injection on body temperature and between 2 and 48 h on stride length and maximal carpal flexion. Modifications on carpal circumference, as well as, on rest angle flexion were observed later on time (between 4-48 h and 8-24 h post LPS administration, respectively. Rest angle flexion was the unique

    Full Text Available Hace unos decenios ya, Claude Lévi-Strauss señaló la universalidad de tres estados que pueden adquirir los alimentos: crudo, cocido, podrido. Las distintas sociedades han desarrollado, a lo largo de su historia y de acuerdo a las pautas culturales que organizan su alimentación, distintos elementos -tecnologías- para facilitar, acelerar o retardar el pasaje de los alimentos de un estado a otro del triángulo culinario. En el presente trabajo se indagó sobre los modos de semiotización de la publicidad vinculada a una de esas tecnologías -los artefactos de cocina- presentes en revistas argentinas de publicación semanal en el período comprendido entre 1940 y 1970. Atendiendo a las modificaciones efectuadas en el período con respecto a los combustibles utilizados para la preparación de alimentos, fue su objetivo esclarecer las transformaciones en la lógica de los atributos que se otorgan al artefacto de cocina en relación con aspectos de la vida cotidiana como: las variaciones de los tiempos de preparación de las comidas y los cambios en la percepción de la higiene del hogar.

    Full Text Available In Argentina, Salix wood is employed mainly in pulp and paper industry. In this country, the brown rotter C oriolellus malicola was found in association with willow plantations. The purpose of this work was to study the anatomical changes caused by C. malicola in willow wood in order to provide information on the effects of brown rot decay in the yield and quality of pulp. Two willow clones were employed: Salix nigra 4 and Salix babylonica x Salix alba cv I 131-25 . Two exposure times were used: 75 and 150 days. The percentages of weight loss produced by this fungus in both clones was ca. 30% at 75 days and ca. 60% at 150 days of decay. C. malicola degraded mainly fibre walls. Microscopically, the loss of cell shape, the presence of transwall fractures and the loss of birefringence were the main anatomical modifications observed. According to our observations decayed Salix wood by C. malicola seems to be inadequate for pulp industry.En la República Argentina la madera de Salix es empleada principalmente en la industria papelera.

    Full Text Available El objetivo del estudio fue analizar la coherencia normativa respecto de la matriz laboral,  la salud y  la ejecución de la pena privativa de la libertad en el ámbito del Servicio Penitenciario de la Provincia de Buenos Aires, Argentina. La metodología consistió en la búsqueda, organización y selección de Leyes, Decretos, Resoluciones y documentos internos de los últimos 30 años, sobre los cuales se realizó un análisis de contenido siguiendo criterios de homogeneidad y pertinencia. El análisis documental muestra que el periodo estudiado se vio signado por modificaciones normativas con objetivos diversos como suprimir la corrupción interna, mejorar las condiciones de vida de los detenidos, dar respuestas a la superpoblación carcelaria y profesionalizar al personal. Se concluye que en las tres aéreas de injerencia delimitadas, tanto por falta de decretos reglamentarios como por persistencia de normas obsoletas e inclusive por el litigio de normativas en oposición, se ha generado un campo institucional que puede ser concebido como anómico, tanto desde las perspectivas de Durkheim como de Merton. Estas modificaciones normativas han fragmentado la lógica institucional y no han logrado modificar las prácticas penitenciaristas anómalas para las cuales fueron diseñadas.

  13. Activities with Argentina

    International Nuclear Information System (INIS)

    In 1989, the US Department of Energy (DOE) responded to the need to redirect resources from weapons production to environmental restoration and waste management by establishing the Office of Environmental Management (EM) and delegated to this office the responsibility of cleaning up the US nuclear weapons complex. Now in its eight year, EM's mission has three central facets: (1) to assess, remediate, and monitor contaminated sites and facilities; (2) to store, treat, and dispose of waste from past and current operations; and (3) to develop and implement innovative technologies for environmental cleanup. To this end, EM has established domestic and international cooperative technology development programs, including one with the Republic of Argentina. Cooperating with Argentine scientific institutes and industries meets US cleanup objectives by: (1) identifying and accessing Argentine EM-related technologies, thereby leveraging investments and providing cost-savings; (2) improving access to technical information, scientific expertise, and technologies applicable to EM needs; and (3) fostering the development of innovative environmental technologies by increasing US private sector opportunities in Argentina in EM-related areas

    2014-01-01

    Soft rocks are a still fairly unexplored chapter in rock mechanics. Within this category are the clastic sedimentary rocks and pyroclastic volcanic rocks, of low to moderate lithification (consolidation, cemen-tation, new formed minerals), chemical sedimentary rocks and metamorphic rocks formed by minerals with Mohs hardness less than 3.5, such as limestone, gypsum, halite, sylvite, between the first and phyllites, graphitic schist, chloritic shale, talc, etc., among the latter. They also include any type of rock that suffered alteration processes (hydrothermal or weathering). In Argentina the study of low-strength rocks has not received much attention despite having extensive outcrops in the Andes and great impact in the design criteria. Correlation between geomechanical properties (UCS, deformability) to physical index (porosity, density, etc.) has shown promising results to be better studied. There are many studies and engineering projects in Argentina in soft rock geological environments, some cited in the text (Chihuído dam, N. Kirchner dam, J. Cepernic Dam, etc.) and others such as International Tunnel in the Province of Mendoza (Corredor Bioceánico), which will require the valuable contribution from rock mechanics. The lack of consistency between some of the physical and mechanical parameters explored from studies in the country may be due to an insufficient amount of information and/or non-standardization of criteria for testing materials. It is understood that more and better academic and professional efforts in improv-ing techniques will result in benefits to the better understanding of the geomechanics of weak rocks.

    Argentina is within the denominated "new industrialised countries", with the characteristic of having high contrasts in the urban population, based on service and industry, and in the rural population, based on agriculture and cattle, still the main sources of wealth in the country. The process of globalisation and the need to compete hard in international markets have provoked high unemployment and the transfer of workers from a formal market to an informal one. Legislation on occupational health is old and it is in the process of being updated. The system of prevention, assistance and compensation for accidents at work and for occupational illnesses has changed from being optative for employers, to the compulsory hiring of private insurance companies. The Government keeps the role of supervisor of the system. There are enough professionals in occupational health, hygiene and safety but not occupational nurses. The teaching is given by many universities and professional associations, some of which have an active profile in the occupational health of the country. PMID:10963410

    This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities.

    Full Text Available This article examines health conditions in the rural areas of Central Argentina, the country’s main region for soy-bean production and export. Health conditions are analyzed through the concepts of emerging and re-emerging diseases in a context of increasing poverty. Data on poverty and health was obtained from both primary sources (trade union, government officials, rural doctors and the South Watch/FA/FODEPAL/UNR working group and secondary sources (IPEC/INDEC, IDESA, Consultora Equis, the Argentine Ministry of Employment, ILO, the Ministry of Health, the Ministry of the Environment, toxicology centers and rural doctors. Analysis of rural health conditions gives cause for concern. There is evidence of deterioration in the social determinants of health such as an increase in rural and urban poverty associated with informal employment and child labor. At the same time lack of government epidemiological and toxicological data appears to hide or distort the reality of health conditions.

El caso de estudio es el área de San Clemente del Tuyú, en el litoral marítimo de la provincia de Buenos Aires, en donde el uso del suelo ha generado modificaciones significativas en el ciclo hidrológico. Se plantearon tres casos de distribución de uso del suelo, se elaboraron mapas isofreáticos para los años 1976, 1987, 2006 y se estimó el volumen de agua dulce disponible al momento de cada relevamiento. Esta información fue integrada a un Sistema de Información Geográfica (SIG. Los resultados obtenidos muestran que existe una relación directa entre la evolución del uso del suelo y la cantidad de agua subterránea almacenada. La zona de médano ha reducido su distribución areal en detrimento de las zonas con urbanización, ese comportamiento se corresponde con la disminución en los volúmenes de agua dulce almacenados para esa área. A modo de conclusión puede expresarse que las modificaciones en el uso del suelo a lo largo del tiempo se reflejan en el comportamiento del acuífero freático. Estudios de detalle recientes demuestran que la urbanización trae aparejada la disminución de las posibilidades de infiltración de los excesos de agua, restringiendo las áreas de recarga natural del acuífero y por consiguiente, las reservas de agua dulce disponibles. Por lo tanto se manifiesta la necesidad de fijar áreas protegidas como reserva y zona de recarga del acuífero con normas de ordenamiento territorial que contemplen la preservación de los mecanismos de recarga natural de las aguas subterráneas.

    Niño Amieva, Alejandra

    2016-04-01

    The authors of the present selection of Latin American Psychiatry texts were characterized by a common deep humanistic attitude. These prolific writers were able to establish or extend the scope of the discipline in which they chose to act, questioning the establishment of rigid boundaries within the framework of a rigorous epistemological reflection. Thus the systematizing spirit of Jose Ingenieros' in the context of positivist evolutionism, resulted in the act of founding a discipline that integrated the biological and the social. In the case of Guillermo Vidal his conception of mental health went beyond the biomedical to consider psychotherapies as an emotional commitment, continence and empathic understanding; with regard to César Cabral his formation and extensive clinical practice resulted in a work defined by the inquiring into the theoretical concepts underlying Psychiatry and Clinical Psychology. This brief selection does not exhaust the issues or the level of ideas and discussions of Psychiatry in Argentina, but constitutes a textual corpus representative of a disciplinary conception understood as scientific and humanistic endeavor.

    The Nuclear Regulatory Authority was established as an autonomous body reporting to the Presidency of Argentina by Act known as the Nuclear Activity National Act, and is empowered to regulate and control the nuclear activity with regard to radiation and nuclear safety, physical protection and nuclear non-proliferation issues. This report details functions and competence of the regulatory body in order to preserve its own independent criterion regarding every aspect of radiological and nuclear safety, and the global strategy of the regulatory system, which are concentrated in the following basics aspects: issue of the corresponding standards; execution of regulatory inspections and audits to verify the compliance with granted licenses and authorisations; independent execution of analyses and studies for the licensing process of nuclear installations; development of technical and scientific aspects associated to radiological and nuclear safety; training of personnel involved in radiological and nuclear safety, either belonging to the Regulatory Body or those working in installations, which perform practices under control. The regulatory control activities are carried out with independence of technical opinions and decisions; administrative autarchy; legal capacity to act in the field of public and private rights, and qualified personnel. The regulatory system complies with the concept of safety culture and its development, and the commitment to nuclear power plants' safety is made clear in design or operation concepts giving priority to safety over economic rentability of the installations. The compliance with Maintenance Programs, In-service Inspection Programs and good operation practices are also part of the commitment. This paper describes the organisational structure of the regulatory body, its human resources, personnel qualification and training, and the necessary financial resources.

    Specimens belonging to the genus Pleurotus were collected growing on fallen trunks of Araucaria araucana, a native tree with a poorly known mycoflora, which grows in Patagonia, Argentina. Fruitbodies were produced in culture on sawdust from an isolated strain. Interspecific pairing tests performed between mating types of Pleurotus from Patagonia and tester strains of P. pulmonarius and P. ostreatus showed the Patagonia strain to be 100% compatible with P. ostreatus and incompatible with P. pulmonarius. Dikaryons obtained on sawdust were fertile, since they were able to produce fruitbodies and viable spores. This is the first documented record of P. ostreatus from Argentina and the first gilled fungus found growing on Araucaria araucana. PMID:12828514

    2015-08-15

    In 2014, nuclear energy generated about 5,257 GWh of electricity or a total share of 4.05 % of the total electrical energy of about 129,747.63 GWh kWh produced in Argentina and there has been a trend for this production to increase. Argentina currently has a nuclear production capacity of 1,010 megawatts of electrical energy. However, when the Atucha 2 nuclear power plant is completed and starts commercial operation, it will add 745 megawatts to this electrical production capacity. There are two sites with nuclear power plants in Argentina: Atucha and Embalse. The Embalse nuclear power plant went into operation in 1984. At the Atucha site, the Atucha-1 nuclear power plant started operation in 1974. It was the first nuclear power plant in Latin America. Construction of Atucha-2 started in 1981 but advanced slowly due to funding and was suspended in 1994 when the plant was 81 % built. In 2003, new plans were approved to complete the Atucha 2. I summer 2014 the plant went critical for the first time. The construction was completed under a contract with AECL.

Con respecto a la categorización anterior de la AHA, se agregaron 94 especies, de las cuales 87 son nuevos taxa, cuatro revalidadas, y otras tres especies fueron incorporadas a la fauna argentina. Asimismo cinco especies fueron extraídas del listado de la fauna de la República Argentina. En comparación con los resultados obtenidas en la categorización del año 2000, observamos que el número de especies Amenazadas se incrementó de cinco a nueve especies y de siete a 68 especies como Vulnerable, incluyendo a los géneros Phymaturus y Anisolepis. Asimismo, se categorizó como Insuficientemente Conocida a 31 especies contra 108 del año 2000. Estos resultados son en parte debido al incremento en el conocimiento sistemático, biológico, ecológico y biogeográficos de las lagartijas y anfisbenas de la Argentina, por el cambio radical de la metodología utilizada y también por los efectos de la presión antrópica sobre las especies

    Full Text Available En el marco de la reactivación económica post crisis del 2001, en la ciudad de Córdoba cobró relevancia y centralidad el accionar de los distintos grupos “desarrollistas” que disponen de un poder diferencial sobre el espacio. Desde el enfoque relacional en que nos posicionamos consideramos que la dinámica y las transformaciones socioespaciales de la ciudad Córdoba no pueden ser comprendidas sin tener en cuenta los intereses, sentidos y estrategias desplegadas por estos grupos. Así, a lo largo del presente trabajo buscamos analizar las continuidades y transformaciones de este sector y su incidencia sobre el espacio urbano. Concluimos considerando que estos grupos se convirtieron en uno de los principales artífices de las transformaciones socio-territoriales. Estas redundaron en una aguda intensificación y mercantilización del suelo urbano consolidando un modelo de ciudad excluyente y privativa para importantes segmentos de la población.

    Background/aim Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. Methods We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. Results The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as “progressives”, “Jurassics” or “conservatives” and “crudos” or “spoiled brats”. BAT marketed Lucky Strike to the “progressives” using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with “nationalistic values” in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. Conclusions The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions. PMID:18299308

    Monitoring of resistance of Aedes aegypti to temephos was implemented in the provinces of Formosa and Misiones, Argentina, as a response to the need to improve the vigilance for the dengue vector in areas of high risk of dengue. Eggs collected in each locality were reared, and susceptibility to temephos was assayed using larval bioassays. A weak decrease in susceptibility of larvae to temephos was observed in Clorinda and Puerto Iguazú, indicating an incipient resistance with a resistance ratio of 3. No control failures have been observed yet, and this program should allow the early detection of a real problem in our country.

    Full Text Available Scholarship on clientelism frequently addresses political clientelism using strong ideological presuppositions and/or neglecting its subjective dimension. In this article I explore political clientelism in a rural community of the province of Formosa, Argentina from the peasants' point of view. The results suggest that peasants consider the clientelist relation as one that recognizes their personal needs, while the bureaucracy of the state does not. Thus, they perceive clientelist ties as legitimate, criticizing only the fact that the provision of resources by patrons takes place only during elections.

Entre las modificaciones introducidas en los hábitos de vida, por esta causa, destacan los cambios dietéticos, tanto cualitativos como cuantitativos. Por la relevancia de la cuestión y ante el escaso conocimiento de los efectos del Ramadán en estudiantes adolescentes que viven en sociedades no islámicas, se plantea como objetivo de este estudio, el análisis de las modificaciones en macronutrientes, ocurridas durante el R, en un grupo de alumnos musulmanes de ambos sexos, con el fin de solucionar y prevenir algunos de los problemas que se plantean en este periodo. Material y método: Se seleccionaron 55 jóvenes musulmanes (24 hombres y 31 mujeres con edades comprendidas entre 15 y 18 años, que realizan el R y se analizó la dieta mediante inventario de 3 días, una semana antes del ayuno y en la segunda semana durante éste. Resultados: En el R, no hay cambios significativos en la ingesta calórica de los hombres y sí en el de las mujeres. Se incrementa el consumo de carbohidratos y proteínas y desciende el de grasas. Discusión: Los cambios en R conducen a una dieta más ajustada a las recomendaciones nutricionales, y a esto parece haber contribuido el hecho de que los participantes llevaron a cabo sus comidas en el seno doméstico donde, a pesar del corte occidental de la población, se deja sentir una importante influencia de las tradiciones y hábitos magrebíes, por el contacto fronterizo con Marruecos.The practice of the Islamic precept of Ramadan (R imposes to

    Full Text Available In this paper we present reports of Yugoslav teachers who held classes to immigrants in Argentina 1939-1944, organized by the government of Kingdom of Yugoslavia. Teachers’ reports to Yugoslav Embassy in Buenos Aires testify of Kingdom of Yugoslavia efforts to oppose assimilation and promote and strengthen “Yugoslav national unity”. The reports also describe general social circumstances of Yugoslav immigrants, show various details from their everyday life and contain valuable data on numerous political, economic, social and cultural problems of this diaspora in Argentina and their relationship with motherland. We believe that archive materials presented in this paper opens numerous questions which could be topics of separate researches. Some of them could be the following: To which extent the teachers’ reports represented the actual situation and to which they were shaped to match policy and expectations of Kingdom of Yugoslavia? What was the actual influence of teachers to spreading the “national unity” among immigrants? Have their work left trace in Yugoslav diaspora and in which way? Beside all of the open issues, it is certain that teachers’ reports contain valuable data on immigrants’ everyday life, curriculum, schooling conditions, relationship with motherland, etc. [Projekat Ministarstva nauke Republike Srbije, br. 47016: Interdisciplinarno istraživanje kulturnog i jezičkog nasleđa Srbije.

    Dengue outbreaks have occurred yearly in Argentina since 1998. A number of candidate vaccines have been tested in endemic countries. The most advanced one was licensed in three countries of Latin America for children over 9 years of age. In the present article the benefits and drawbacks of these vaccines as well as the challenges for the implementation of a vaccination strategy in Argentina are discussed. Furthermore, a risk stratification strategy with new criteria and a multidisciplinary vision is suggested as a possible path for the assessment of the pertinence of a vaccination program in areas showing the highest risk of dengue transmission and/or for people at the greatest risk of developing severe dengue. It is also suggested that the definition regarding the status of endemicity should take into account the local realities. Finally, this paper proposes a broad discussion on the evidences, the expected impact and instrumental aspects that would be involved in the incorporation of a dengue vaccine, marketed or in development, into the national immunization program, and especially which subpopulation should be targeted for the immunization strategy to be cost-effective.

  17. Spent Fuel Management of NPPs in Argentina

    International Nuclear Information System (INIS)

    There are two Nuclear Power Plants in operation in Argentina: “Atucha I” (unique PHWR design) in operation since 1974, and “Embalse” (typical CANDU reactor) which started operation in 1984. Both NPPs are operated by “Nucleoeléctrica Argentina S.A” which is responsible for the management and interim storage of spent fuel till the end of the operative life of the plants. A third NPP, “Atucha II” is under construction, with a similar design of Atucha I. The legislative framework establishes that after final shutdown of a NPP the spent fuel will be transferred to the “National Atomic Energy Commission”, which is also responsible for the decommissioning of the Plants. In Atucha I, the spent fuel is stored underwater, until another option is implemented meanwhile in Embalse the spent fuel is stored during six years in pools and then it is moved to a dry storage. A decision about the fuel cycle back-end strategy will be taken before year 2030. (author)

  18. Central Argentina de Elementos Modulares (CAREM)

    International Nuclear Information System (INIS)

    CAREM (Central ARgentina de Elementos Modulares) is an Argentine project to develop, design and construct an innovative, simple and small nuclear power plant (NPP). This plant has an indirect cycle reactor with distinctive and characteristic features that greatly simplify the design and contribute to a high safety level. Some of the high-level design characteristics of the plant are: an integrated primary cooling system; self-pressurized primary system and safety systems relying on passive features. CAREM is a CNEA (Comision Nacional de Energia Atomica) project, which has been jointly developed with INVAP, an Argentine company. The CAREM concept was first presented in March 1984, in Lima, Peru, during the IAEA's conference on small and medium sized reactors. Chronologically CAREM was one of the first of the present new generation of reactor designs. The first step of this project is the construction of the prototype of about 27 MW(e) (CAREM-25). This project allows Argentina to sustain activities in nuclear power plant design, assuring the availability of updated technology in the mid-term. The design basis is supported by the cumulative experience acquired in research reactor design, construction and operation and pressurized heavy water reactor (PHWR) operation, as well as development of advanced design solutions. The Generation IV International Forum (GIF) recognized CAREM as an international near term deployment (INTD) reactor

    The Paced Auditory Serial Addition Test (PASAT) is one of the most used neuropsychological tests to assess information processing speed and working memory in brain injured patients. This study was carried out with the purpose of obtaining normative data for the PASAT-3″ in a healthy Argentinean population, which would result in a reference control population. The PASAT-3″ was administered in a sample of 296 healthy voluntary subjects, born and living in Argentina. The age range went from 20 to 70 years-old. The level of education was 0 to 13 or more years of schooling. The sample obtained a mean of 44.60 (SD = 10.72) in the PASAT-3″. It was found that the score obtained in the PASAT-3″ was related to the age and the level of instruction of the participants. Their performance diminished as age increased and, conversely, it increased as the level of instruction was higher. Normative data was obtained for a Latin American population from Argentina. Percentile distributions obtained by decades of age and different levels of education should be considered as useful reference values for clinicians and investigators when applying the PASAT-3″ to assess cognitive function in different pathologies.

    Fusarium temperatum and Fusarium subglutinans isolated from the Northwest region (NOA region) of Argentina were characterized using a polyphasic approach based on morphological, biological and molecular markers. Some interfertility between the species was observed. The phylogenetic analysis showed that the two species represented two clades strongly supported by bootstrap values. The toxigenic profile of the strains was also determined. F. temperatum strains were fusaproliferin and beauvericin producers, and only some strains were fumonisin B1 producers. All F. subglutinans strains produced fusaproliferin but none produced beauvericin, indicating a potential toxicological risk from maize harvested in the NOA region of Argentina. This study provides new information about F. temperatum isolated from maize in Argentina.

    Full Text Available Durante el siglo XVII los sucesivos reyes de Castilla y Aragón habían perdido parte del control político y económico de sus colonias americanas. Esta circunstancia favoreció el florecimiento económico y social de las colonias y la conformación de élites locales que tenían cierta influencia en la administración colonial. La situación cambió a lo largo del siglo XVIII con la llegada de los Borbones1, que tomaron medidas para aumentar el control político y económico de la metrópoli sobre las posesiones de ultramar. La política colonial de Carlos III, inspirada en el despotismo ilustrado, buscó generar modificaciones “desde arriba” sin cambiar las relaciones sociales2. Entre las principales Reformas Borbónicas se encuentra la creación del Virreinato del Río de la Plata (1776, que transformó a Buenos Aires en la nueva sede de gobierno. El mismo estaba constituido por parte de los territorios de los siguientes países actuales: Bolivia (Alto Perú, Paraguay, Uruguay (Banda Oriental y Argentina. Uno de los principales objetivos era frenar el contrabando a favor del monopolio mercantil de la metrópoli, dado que por el lejano puerto de Buenos Aires se producía un comercio ilegal3, con la salida de metales preciosos altoperuanos y la entrada de esclavos y productos manufacturados europeos introducidos por ingleses4 y portugueses5.

  15. Argentina's regulatory body: its communication activities

    International Nuclear Information System (INIS)

    Full text: The Nuclear Regulatory Authority of Argentina (ARN) is empowered to regulate and control the nuclear activity with regard to radiation and nuclear safety, physical protection and nuclear non-proliferation issues. It must also advise the Executive on issues under its purview. The objective of the Nuclear Regulatory Authority is to establish, develop and enforce a regulatory system applicable to all nuclear activities carried out in Argentina. Two of the goals of this regulatory system are to provide an appropriate standard of protection for individuals against the harmful effects of ionizing radiation, and to maintain a reasonable degree of radiological and nuclear safety in the nuclear activities performed in Argentina. The responsibility of the radiation protection community in performing the tasks to accomplish this goals is twofold. On one hand, it must ensure a high technical quality in performing these functions. It must also provide information on its activities which has to be accurate, comprehensive and understandable. The way a society understands the concept of 'risk' needs to be kept in mind. Risk perception is the subjective judgment that people make about the characteristics and severity of a risk. Cultural theory refers to theories of risk perception that focus on culture, rather than individual psychology as an explanation for differences in risk judgments. It is widely agreed that trust is a key factor in influencing people's perceptions of risk. It is understood there are two main ways trust may impact in risk perceptions: an activity is perceived as more risky if the people or agencies managing it are perceived as untrustworthy; and information presented by trusted sources is given more credibility than information from untrusted sources. One of the primary purposes of ARN's Communication Program is to provide a means whereby those engaged in radiation protection activities may communicate more readily with each other and the public and

Although immigration restrictions increased over time Argentina remained relatively open to mass migration until the 1930s in contrast with the United States. The quantitative evidence presented here suggests that there were economic reasons to restrict immigration prior to the 1930s, namely rising inequality and a declining demand for workers.

    Common vampire bat populations distributed from Mexico to Argentina are important rabies reservoir hosts in Latin America. The aim of this work was to analyse the population structure of the rabies virus (RABV) variants associated with vampire bats in the Americas and to study their phylodynamic pattern within Argentina. The phylogenetic analysis based on all available vampire bat-related N gene sequences showed both a geographical and a temporal structure. The two largest groups of RABV variants from Argentina were isolated from northwestern Argentina and from the central western zone of northeastern Argentina, corresponding to livestock areas with different climatic, topographic and biogeographical conditions, which determined their dissemination and evolutionary patterns. In addition, multiple introductions of the infection into Argentina, possibly from Brazil, were detected. The phylodynamic analysis suggests that RABV transmission dynamics is characterized by initial epizootic waves followed by local enzootic cycles with variable persistence. Anthropogenic interventions in the ecosystem should be assessed taking into account not only the environmental impact but also the potential risk of disease spreading through dissemination of current RABV lineages or the emergence of novel ones associated with vampire bats.

    As part of the new German-Argentinian Solar Observatory in El Leoncito, San Juan, Argentina, a new ground-based solar telescope (MICA) began to operate in August 1997. MICA is an advanced mirror coronagraph, its design being an almost exact copy of the LASCO-C1 instrument. Since its installation, it has been imaging the inner solar corona (1.05 to 2.0 solar radii) in two spectral ranges corresponding to the emission lines of the Fe XIV and Fe X ions. The instrument can image the corona as fast as every minute. Thus, it is ideally suited to study fast processes in the inner corona. In this way, it is a good complement for the LASCO-C1 instrument. After a brief review of the instrument, we present some recent observations showing the capabilities of the instrument.

    Full Text Available While research on social ideas of nature focused on the discursive side of environmental rhetoric during the last decade of the twentieth century, the visual turn has introduced the analysis of its visual facet: the study of the visual representation of nature in photographs, films, paintings and media among many other image-based media. However, scarce attention has received the study of what is provoked by environmental images as well as how they shape our imagination and memory of environmental issues. Based on the analysis of mental maps created by 215 subjects -all of them students of the undergraduate programs of the Faculty of Humanities at Universidad Nacional del Centro de la Provincia de Buenos Aires Province (Argentina in 2013- as the starting point to identify images that have become constitutive environmental memory, the article discusses the role of environmental images in shaping both our ways of looking to nature and our understanding of environmental issues.

  13. Republic of Argentina: Argentina is the envy of other Latin American countries.

    1984-05-01

    Argentina's economic and political history may appear grim by US standards, but it is envied by many other Latin American nations, and by Latin American standards its demographic situation is enviable as well. A low population growth rate combined with abundant natural resources means that the poverty of its neighbors has not hit Argentina. Almost everyone eats well and the staple is beef -- about 240 pounds per capita per year. Final figures for the 1980 census of population and housing report a total of 27.9 million people, an increase of 17% from the 23.8 million people counted in 1970. The average annual rate of increase was 1.5% a year. With the exception of Uruguay, this is the lowest rate of increase in continental Latin America. The birthrate of 24 births/1000 population is third only to Chile and Uruguay as the lowest in continental Latin America, although the death rate is about average at 9/1000. After several decades of decline, the death rate is rising again because the population is aging. A current problem is the emigration of Argentinians to other countries, a problem that is most severe among highly trained professionals. Over 1/3 of those who leave Argentina come to the US, with Spain and Canada receiving the next highest numbers. At its current growth rate, Argentina's population will double in 46 years. It is estimated that the population was 29.1 million in 1983; it is projected to be 34.5 million by the year 2000 and 39.6 million by 2020. Over 1/3 of the population live in and around Gran Buenos Aires, the largest metropolitan area in South America and among the ten largest in the world. There is a large core of Spanish descendents still living, but some other European countries are well represented also. The 1980 census recorded 7.1 million households; the average number of persons per household was 3.9. There were 8.2 million dwellings counted in 1980, with an average of 3.3 people per dwelling. 13% of all dwellings were unoccupied at the

Cesco (El Leoncito), gracias al esfuerzo de la gente del Max Planck Institut für Aeronomie (Alemania), del OAFA y del IAFE. Dicho coronógrafo forma parte de un programa de ciencia bilateral entre Alemania y Argentina. El propósito del mismo, en conjunción con otros telescopios solares y terrestres, es contribuir a un mejor entendimiento de cuestiones fundamentales de la física solar. Para ello, ya está observando la corona de emisión en el verde (Fe XIV), rojo (Fe X) y Hα entre 1.05 y 2 radios solares aproximadamente. El diseño del instrumento, el cual fuera ya presentado en esta misma reunión en La Plata en 1996, es esencialmente similar al del telescopio LASCO-C1 a bordo del Solar Heliospheric Observatory (SOHO). La adquisición de datos se realiza con un CCD de 1280x1024 pixels, codificando en 12 bits, pudiendo ser el mismo operado en forma remota. En esta reunión presentaremos algunas de las observaciones realizadas durante la puesta a punto del instrumento en el período julio-setiembre de 1997. Asimismo expondremos cómo y por qué sus resultados complementarán a los de su par en el espacio.

It can be seen that there are possible 3 potential protein were post-translational modifications with 1 possible single substitution. This data can be useful for further study on hepatitis B virus mutant as well as planning for new vaccine production.Las modificaciones postranslacionales que sufren las proteínas controlan muchos procesos biológicos. Esto es también válido en el caso de los virus, incluyendo el de la hepatitis B. Sin embargo, no se han realizado estudios en profundidad de la totalidad de la proteína grande de superficie del virus de la hepatitis B. En el presente estudio, se han determinado las modificaciones postranslacionales que son posibles en esta proteína de la cubierta viral empleando para ello una técnica bioinformática estándar. Además, también se determinaron las sustituciones de un solo aminoácido que son posibles en la proteína grande de la superficie del virus de la hepatitis B. De este análisis podemos deducir que existen 3 posibles modificaciones translacionales en esta proteína y una potencial sustitución simple. Estos datos pueden ser útiles tanto para posteriores estudios sobre el virus mutante de la hepatitis B, como para la producción de una nueva vacuna contra este virus.

    The blue land planarian Caenoplana coerulea is reported from Argentina (Buenos Aires province). We found C. coerulea in the east central region of Argentina in anthropic environments. The specimens that we found have the characteristic of the species found in others regions; that is, a bluish dorsal surface with a yellow mid-dorsal stripe and eyes forming a single row around the anterior tip, clustered laterally. This is the first record of this species from the Neotropical Region, and togeth...

  17. Interannual variability of temperature spells over Argentina

    This work is aimed at studying the interannual variability of surface temperature cold spells and warm spells due to cold-and warm-air incursions. The effect of the ENSO event on the occurrence of extreme spells having three different indices was studied. In order to track changes during the 1959/96 period, spell parameters, persistence and intensity, have been studied from daily temperatures. The number of extreme spells per year show low frequency variability plus a biennial variability, which is more important in its intensity than in its persistence, and in summer rather than in winter. The number of extreme warm spell increase until the end of the sisties and seventies, reflecting and increase of northeasterly flow. From then onwards, the trend starts to decline significantly over northern Argentina. The interannual variability of extreme winter cold spells increases from the 80's onwards, indicating the variations of anticyclone permanence over the country. Cases are more numerous in the latest years. Extreme spell occurrence in northern Argentina is closely linked to the El nino phenomenon. Winter warm spells are more persistent in an El Nino (0) year and more intense and persistent in the year following El Nino. In summer, however, there is either no difference, or the relationship is reversed, resulting in more intense situations in November and December in the case of La Nina. Cold spells reaching the Northeastern most part of the country are more persistent when La Nina occurs, the conclusions being that the region would be affected by extreme cold spells when La Nina is active. [Spanish] En este trabajo se estudia la variabilidad interanual de las olas de calor y frio extremas sobre la Argentina, como la manifestacion de irrupciones extremas de aire tropical y polar.

    Full Text Available This paper analyses the culture of milk and it includes both the micro social aspects of household consumption and the economic macro aspects related to milk production and their market and the welfare distribution in public policies against poverty. The hypothesis is that in Argentina there is a real culture of milk, which gives meaning to consumption, and marks the different income groups within society, as well as their gender and age. But since approximately 20 years ago, in accordance with the restructuring of the dairy industrial complex, that culture of milk has been changing, and its most outstanding features are the following: abandonment of milk as the emblematic food for children and its extension to the adult “formal” consumption; milk is no longer the knowledge of women and becomes the knowledge of experts; increase in milk consumption (dairy products in general as food gets feminine, infantile, medicated, globalised and segmented.Este artículo sobre la cultura de la leche analiza los aspectos microsociales del consumo en el hogar y los aspectos macro de la economía que hacen a la industria lactea y al mercado junto a la distribución asistencial del estado en los programas contra la pobreza. La hipótesis es que en Argentina existe una verdadera cultura de la leche, que da sentido al consumo, marcando con el alimento los diferentes sectores de ingreso de la sociedad, los géneros y las edades. Pero desde hace aproximadamente 20 años, en consonancia con la reconversión del complejo industrial lácteo, esta cultura de la leche esta cambiando, se describen sus aspectos mas salientes tales como : el abandono de la leche como alimento emblemático de los niños y su extensión al consumo “formal” adulto ; deja de ser un alimento rutinario cuyo saber usar residía en las mujeres y su uso pase a ser cosa de especialistas ; a medida se feminiza, infantiliza, medicaliza, globaliza y segmenta la alimentación en general

    2008-03-01

    A report and an updated list with comments on the species of freshwater molluscs of Argentina which covers an area of 2 777 815 km2 is presented. Distributions of Gastropoda and Bivalvia families, endemic, exotic, invasive as well as entities of sanitary importance are also studied and recommendations on their conservation are provided. Molluscs related to the Del Plata Basin have been thoroughly studied in comparison to others areas of the country. This fauna exhibits relatively the biggest specific richness and keeps its affinity with the fauna of other regions of the basin in areas of Paraguay and Brasil. The 4 500 records of molluscs considered in this paper arise from the study of the collections of Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires; Museo de La Plata, La Plata and Fundación "Miguel Lillo", Tucumán. These institutions keep very important collections of molluscs in southern South America. Field information has recently been obtained and localities cited by other authors are also included in the data base. Until today, 166 species have been described, 101 belonging to 10 families of Gastropoda and 65 to 7 of Bivalvia. Families with highest specific richness are Lithoglyphidae (22) and Sphaeriidae (25), respectively. The number of endemic species (those present only in Argentina) by family is: Gastropoda: Ampullariidae (1), Cochliopidae (10), Lithoglyphidae (11), Thiariidae (3), Chilinidae (11), Lymnaeidae (2) and Physidae (2?); Bivalvia: Hyriidae (1?); Etheriidae (1?) and Sphaeriidae (10). Families with a distribution that comprise almost the whole country are: the Sphaeriidae and the gastropods Cochliopidae, Chilinidae and Lymnaeidae. Families Erodonidae and Solecurtidae (Bivalvia) were registered in mixohaline environments from Buenos Aires province. Gastropod families Thiaridae and Glacidorbiidae show a very restricted distribution. The rest of the families are present mainly in the center and north of the country

  5. Economy-wide impacts of biofuels in Argentina

    International Nuclear Information System (INIS)

    Argentina is one of the world's largest biodiesel producers and the largest exporter, using soybeans as feedstock. Using a computable general equilibrium model that explicitly represents the biofuel industry, this study carries out several simulations on two sets of issues: (i) international markets for biofuel and feedstock, such as an increase in prices of soybean, soybean oil, and biodiesel, and (ii) domestic policies related to biofuels, such as an introduction of biofuel mandates. Both sets of issues can have important consequences to the Argentinean economy. The simulations indicate that increases in international prices of biofuels and feedstocks would increase Argentina's gross domestic product and social welfare. Increases in international prices of ethanol and corn also can benefit Argentina, but to a lesser extent. The domestic mandates for biofuels, however, would cause small losses in economic output and social welfare because they divert part of biodiesel and feedstock from exports to lower-return domestic consumption. An increase in the export tax on either feedstock or biodiesel also would lead to a reduction in gross domestic product and social welfare, although government revenue would rise. - Highlights: ► Argentina is one of the largest biodiesel producer and exporter using soybeans. ► Economy-wide impacts are assessed using a CGE model for Argentina. ► Policies simulated are feedstock and biodiesel price change, and domestic mandates. ► Increases in international prices of biofuels and feedstock benefit the country. ► Domestic mandates for biofuels cause small losses in economic output

    Full Text Available As an answer to the new disparities and inequities which emerged from the health reforms in Argentina form the 1990´s, it appears the need to guarantee the health as a right. As a consequence, an important judicial activism begins to unfold in order to achieve greater guarantees in matters of health. Here, judicial activism refers to the strategic use of the law courts by organizations dedicated to the struggle of public interest and to the use of the law courts by private individuals to channel the complaints against the State or against health service providing companies. At present, both the Supreme National Court of Justice and the lower courts have dealt with an important number of cases related to the right to health. In the cases selected in this article, we analyze the type of conflict and the judicial answer, together with the possible effects of certain court decisions about the rules that govern the health system as finally conformed

    In Argentina, health is not considered a state policy, and it does not benefit from effective action in all areas of government. The budget is essentially used up by structural costs, and despite having made progress in some areas such as vaccinations, there is little impact on the community as a whole from the promotion of health and the prevention of prevalent chronic illnesses linked to metabolism and lifestyle. The biggest health expenditure is private, including so-called "out-of-pocked spending," which leads to inequality, with over 40% of the population without explicit health coverage. In the national systems, coverage is linked to formal employment and Obras Sociales and is essentially managed by trade unions. Social determinants therefore continue leading to illness, which the health system then attempts to cure at enormous human and financial cost. Recommendations of international bodies (PAHO, WHO, FLH, IHF) stress the importance of organizing state and private RISS, but very little has been done in this regard. Right to healthcare is already required, but it's a long way form being sufficient. The whole population needs to be provided explicit and effective universal health coverage, in order to ensure healthcare and equality, and organize healthcare networks which make awareness, promotion, prevention, and rehabilitation more effective for all, using existing, high-level structural and human resources.

  12. National uranium development programme in Argentina

    International Nuclear Information System (INIS)

    The initial survey of Argentine uranium resources was completed in 1959. This survey, conducted over a 12-year period, covered approximately 1,000,000 square kilometres. The exploration programme used a combination of airborne, carborne, and hand-held radiometric surveys, together with supporting geochemical and emanometric evaluations. Nearly 1000 anomalies were found, and of these 500 were selected for further study. This work included detailed geological, radiometric and emanometric surveys, as well as 230,000 metres of drilling and 35,000 metres of trenching and tunnelling. As a result 200 of the anomalies were reclassified as deposits of four different size categories. Eighty of the deposits were estimated to contain 10 tonnes U3O8, 15 were placed in the 100 tonnes U3O8 category, 7 were designated as 1000 tonnes deposits, and one was estimated to contain approximately 16,000 tonnes of U3O8. The uranium resources of Argentina are presently estimated to be 31,000 tonnes U3O8, based on a cost of up to US $80 per kilogram U3O8. An additional 12,000 tonnes U3O8 are available if a US $80-130 per kilogram U3O8 cost category is used. The overall uraniferous geological potential based on favourability criteria is estimated to be around 400,000 tonnes U3O8. (author)

    Full Text Available The development of alternative agricultural production can take different forms. In Argentina there is an important diversity of species available to be incorporated into production systems, giving support for the use of natural resources based on taking advantage of the regional fauna. Moreover the use of different animal species can be incorporated under the concept of the optimization of flows of energy and materials, tending to minimize the environmental impact of livestock production, and also to make more efficient use of the ingredients required for developing the activity. The integration of non-traditional species (minilivestock within the context of sustainable agricultural development was the motivation for the present study A module for raising Myocastor coypus (coypu or false nutha was developed, to which was linked a module for raising Eisenia foetida (the socalled red worm, in both cases with a dual purpose. Preliminary estimates were made of the productive aspects of both species, as well as an analysis of their integration, to understand the extent to which diversification linked with complementation tends to optimize the system.

    Objective To investigate genetic etiologies of preterm birth (PTB) in Argentina through evaluation of single-nucleotide polymorphisms (SNP) in candidate genes and population genetic admixture. Study Design Genotyping was performed in 389 families. Maternal, paternal, and fetal effects were studied separately. Mitochondrial DNA (mtDNA) was sequenced in 50 males and 50 females. Y-chromosome anthropological markers were evaluated in 50 males. Results Fetal association with PTB was found in the progesterone receptor (PGR, rs1942836; p= 0.004). Maternal association with PTB was found in small conductance calcium activated potassium channel isoform 3 (KCNN3, rs883319; p= 0.01). Gestational age associated with PTB in PGR rs1942836 at 32 –36 weeks (p= 0.0004). MtDNA sequencing determined 88 individuals had Amerindian consistent haplogroups. Two individuals had Amerindian Y-chromosome consistent haplotypes. Conclusions This study replicates single locus fetal associations with PTB in PGR, maternal association in KCNN3, and demonstrates possible effects for divergent racial admixture on PTB.

    Full Text Available The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, potentially infested places were entomologically evaluated. T. infestans was only detected in a hen building for egg production, which housed approximately 6,000 birds. A total of 2,930 insects were collected. Density was about 9 triatomines/m². The proportions of fifth instar nymphs and adults were significantly higher than those of the other stages (p<0.001. The number of triatomines collected largely exceeded the highest domestic infestation found in one house from rural endemic areas of Argentina. Though triatomines were negative for Trypanosoma cruzi, they could acquire the parasite by coming in contact with infected people living in GBA. Besides, the numerous and widely distributed places housing hens and chickens, would favor the settlement of the vector. Together, both facts may constitute a risk of parasitic vectorial transmission. It is recommended to intensify systematic activities of vector search and case detection in GBA.

    Full Text Available La rata eSMT derivó del cruzamiento de eSS y b, líneas de la cepa IIM. eSS es un modelo de diabetes tipo 2 sin sobrepeso; b desarrolla obesidad moderada e intolerancia tardía a la glucosa. Fueron comparados características metabólicas y hallazgos histopatológicos del páncreas endocrino entre eSS y eSMT. Cotejados con eSS, los animales eSMT jóvenes son más corpulentos y desarrollan hiperglucemia de ayuno e intolerancia a la glucosa más precoces e intensas. En los machos eSMT de 6 y 9 meses existen islotes de formas alteradas y con fibrosis, detectándose esporádicas imágenes de apoptosis. En los de un año se tornan más pequeños y escasos, remedando la histoarquitectura de los machos eSS en el segundo año de vida; posteriormente los islotes van disgregándose, a la vez que muestran ocasionales mitosis y se observa nesidioblastosis. Se sugiere que estas modificaciones dinámicas constituyen una respuesta a la hiperglucemia. Las hembras eSS conservan por más tiempo la estructura insular y tienen menores alteraciones de la glucemia. El dimorfismo sexual del síndrome diabético de eSMT es atenuado respecto de eSS. La construcción de una tipología de individuos mediante el análisis multivariado separó tres clusters, evidenciando diferencias genéticas, etáreas y de sexo.The eSMT rat is derived from the crossing of eSS and b, both lines belonging to the IIM strain, while eSS is a model of type 2 diabetes without overweight and b develops moderate obesity and late glucose intolerance. Metabolic characteristics and histopathological findings in endocrine pancreas of eSS and eSMT were compared. Young eSMT animals are more robust than eSS and develop more intense fasting hyperglycemia and glucose intolerance at an earlier age. eSMT males of 6 and 9 months show islets with altered shapes and fibrosis, as well as sporadic images of apoptosis. At 12 months of age, islets are reduced in number and size, resembling the histoarchitecture of

    Full Text Available Objecte: L’objectiu del treball és analitzar les modificacions realitzades en els Estatuts de les cooperatives per adaptar el capital social a les normes comptables i veure quins han estats els efectes econòmics de l’adaptació del capital social en la situació patrimonial i econòmica de les cooperatives. Disseny/metodologia: Per dur a terme l’estudi s’ha demanat al Registre de Cooperatives  els Estatuts i els comptes anuals, per al període 2010-2011, de les cooperatives objecte de l’estudi. En primer lloc s’han revisat els Estatuts per veure quins articles han modificat o han introduït en relació a la nova normativa comptable. En segon lloc s’ha creat una base de dades amb els comptes anuals de les cooperatives per tal d’analitzar la situació econòmica i financera de les mateixes a través d’un anàlisi de les masses del balanç i de ràtios. Aportacions i resultats: S’ha identificat el percentatge de cooperatives que han decidit adaptar els Estatuts a la reforma comptable i el criteri adoptat per les mateixes. Els resultats mostren que les cooperatives han adaptat majoritàriament els seus Estatuts i que els efectes de l’aplicació de les normes comptables adaptades a la NIC 32 consisteixen en una disminució del patrimoni net i un augment de l’endeutament. Limitacions: La dificultat temporal per anar obtenint els comptes anuals i els Estatuts de les diferents cooperatives existents a Catalunya. Implicacions pràctiques i socials: Degut a que des de 2011 totes les cooperatives espanyoles han d'aplicar les normes comptables adaptades a la NIC 32, els resultats d'aquest treball de recerca poden ser útils per a diferents grups d'interès, no solament per a les pròpies cooperatives, sinó també per altres organismes cooperatius per a què puguin realitzar les valoracions que creguin convenients i per a les entitats financeres, per tal que puguin tenir-los en compte a l'hora de prendre decisions.

    Full Text Available The blue land planarian Caenoplana coerulea is reported from Argentina (Buenos Aires province. We found C. coerulea in the east central region of Argentina in anthropic environments. The specimens that we found have the characteristic of the species found in others regions; that is, a bluish dorsal surface with a yellow mid-dorsal stripe and eyes forming a single row around the anterior tip, clustered laterally. This is the first record of this species from the Neotropical Region, and together with Bipalium kewense are the only 2 species of exotic terrestrial planarians so far recorded in Argentina.La planaria terrestre azul Caenoplana coerulea se registra para el centro este de Argentina (provincia de Buenos Aires, en ambientes antropizados. Los ejemplares encontrados presentan las características de la especie registrada en otras regiones, con una superficie dorsal azulada y una hilera medio dorsal amarilla, y ojos formando una hilera alrededor del extremo anterior, agrupados lateralmente. Es la primera vez que se cita dicha especie en la Región Neotropical, y junto a Bipalium kewense son las únicas planarias terrestres exóticas registradas en Argentina.

  20. Biotechnology in Argentina: New products, new multilateral challenges

    Full Text Available Since 20 years ago, a public-private alliance has transformed Argentina into a remarkable global actor in developing biotechnological products for food and renewable energies. This strategic alliance resulted in the boosting of scientific knowledge, the extension of the production boundary, the expansion of international trade and the creation of the conditions for an integral development. Furthermore, given the characteristics of biotechnology as a new phenomenon, wto has become the field within where a number of disputes take place, disputes which not only controvert trade issues, but also the State’s limits to design and apply public policies on the matter at issue. As a consequence, the present article seeks to, on the one hand, describe how Argentina built its public policy on Biotechnology and, on the other hand, analyze the challenges that Argentina faces within the multilateral trade system

    Full Text Available ESTE trabalho discute alguns aspectos da evolução econômica recente do Brasil, da Argentina e de outros países da América do Sul. Tendências econômicas e intelectuais perigosas, tais como a "globalização", o chamado Consenso de Washington, a dolarização e as negociações da Alca (Área de Livre Comércio das Américas, perderam ímpeto e a América do Sul está se movendo gradualmente na direção de um posicionamento mais independente na condução das suas política econômicas e internacionais. As mudanças foram muito mais significativas na Argentina do que no Brasil e isso se tornou fonte de alguma tensão entre os dois principais países sul-americanos. Não obstante, uma aliança estratégica entre Argentina e Brasil continua sendo a pedra angular da integração da América do Sul.THIS PAPER discusses some aspects of the recent economic evolution of Brazil, Argentina and other South American countries. Dangerous economic and intellectual trends, such as "globalization", the so-called Washington Consensus, dollarization, and FTAA (Free Trade Area of the Americas negotiations, have lost momentum and South America is moving gradually towards a more independent stance in the conduct of its economic and foreign policies. Changes have been much more significant in Argentina than in Brazil and this has become a source of some tension between the two major South American countries. Nevertheless, a strategic alliance between Argentina and Brazil remains the corner stone of South American integration.

  8. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Argentina

    International Nuclear Information System (INIS)

    Argentina is a predominantly lowland area of 2,789,240 square kilometers. The capital is Buenos Aires. The entire length of Argentina is bordered on the west by the Andes Mountains. Tile Northwest Andes-Piedmont region consists of deep valleys containing salt basins and volcanoes, and is an earthquake zone. Patagonia, in the south, is essentially an arid region of windy plateaus and valleys. The southern Andes are narrower and lower than the northern Andes and in the extreme south contain glaciers and ice fields. The east-central plain (Pampa) of Argentina has dry and humid sectors and contains most of the population. The largest rivers are chiefly in the northeast, many having only seasonal flow. There has been extensive surface and subsurface exploration for uranium in Argentina for over 20 years. Although most of the work has been performed by the CNEA, advisors from the U.S. and from the IAEA have also taken part. Private industry has been involved, but apparently only on a small scale. In the OECD report of 1970, it was stated that 400,000 square kilometers of Argentina appear very favorable for uranium while an additional 900,000 square kilometers offer fair possibilities. Uranium exploration to date suggests that sandstones of Permian and Cretaceous ages exposed in Western Argentina in the Cordillera are very promising for discovery of new deposits. Past CNEA estimates have indicated that there is considerable hope for new discoveries in those areas where reserves are now known. In addition to the known uraniferous provinces which are indeed favorable for further exploration, there are several other large areas that warrant attention. There are, for example, in the Santa Cruz area of about 15,500 square kilometers Cretaceous and Tertiary sediments with favorable facies for uranium deposition. In the Patagonia Cordillera, Jurassic, Cretaceous, and Tertiary sediments are of interest for prospecting, These rocks contain carbonaceous material and have been

  11. The Limits to Dollarization in Ecuador: Lessons from Argentina

    Directory of Open Access Journals (Sweden)

    Matias Vernengo

    2015-08-01

    Full Text Available The paper draws lessons from the failed Argentine experience with convertibility to highlight the dangers of dollarization in Ecuador. Argentina’s currency peg to the US dollar was successful in reducing inflation but given the overvalued real exchange rate, created burgeoning twin deficits and a chronic dependency on foreign capital. Ecuador too suffers from chronic current account imbalance. In contrast to Argentina, Ecuador seems to be relying on remittance income to close its external financing gap. Though perhaps this model is less unstable than that of relying on foreign capital it is no more sustainable. The paper closes with a realistic critique of thisdevelopment strategy.

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

  18. Jurassic Paleoclimates in Argentina, a review

    Directory of Open Access Journals (Sweden)

    Wolfgang Volkheimer

    2008-12-01

    Full Text Available New paleoclimatic evidence from palynologic and vertebrate proxies provides more detailed data on climatic change during the Jurassic in Argentina. Comparison with paleomagnetic data shows that the Neuquén basin shifted from the highest paleolatitudes (50ºS, by the end of the Triassic until the end of the Sinemurian. During the Pliensbachian-Toarcian it moved northward, reaching the lowermost paleolatitudes (25ºS, and subsequently (Middle to Late Jurassic the area moved again and attained eventually a position similar to its present-day position (30ºS. These movements are reflected in the Jurassic palynofloras. The high frequency of the pollen genus Classopollis (Cheirolepidiacean gymnosperms is of special paleoclimatic importance in the Argentinian Jurassic, as it is indicative of seasonal aridity or semiarid conditions during large intervals of this Period. During the shift of the South American continent to the northernmost position, the arrival of an important group of Araucariaceae, represented by Callialasporites spp., in the Toarcian could indicate an amelioration related to more humid conditions. Jurassic dinocyst assemblages studied in the Neuquén basin have proved to be useful paleoclimatic and paleobiogeographic proxies. Abundant remains of marine crocodiles in the Mid- and Late Jurassic of the Neuquén basin indicate warm water temperatures for this basin, probably in excess of 20° C. The occurrence of abundant turtles and other ectothermic vertebrates in the Middle Jurassic Cañadón Asfalto Formation of Chubut is in general accordance with the warm climate indicated for this unit by geologic evidence.

Se analizaron número, proporción y tasas crudas y ajustadas para cada tipo de muerte (catalogadas según la CIE-9a y CIE-10a, el total por año y el promedio anual del período, sexo y edad. Los perfiles globales de los dos países presentaron tendencia creciente, pero Brasil mostró valores superiores de muertes y homicidios por armas de fuego en todo el período. A partir de los resultados se discute la hipótesis: el perfil de Brasil, particularmente el de homicidios por armas de fuego, es consecuencia no solo de la violencia social que responde a la persistentemente alta desigualdad y exclusión en que vive gran parte de la población, sino también al surgimiento, expansión y fortalecimiento de diversos grupos armados en ese país. El perfil argentino resultaría en parte del aumento de la violencia social también como respuesta al deterioro socioeconómico imperante, y por otra parte, sería consecuencia de la histórica monopolización de la violencia por parte del Estado

    2011-02-01

    We describe the movement of cattle throughout Argentina in 2005. Details of farm-to-farm and farm-to-slaughter movements of cattle were obtained from the Sanitary Management System database (Sistema de Gestión Sanitaria, SGS), maintained by the National Service for Agrifood Health and Quality (SENASA). Movements were described at the regional and district level in terms of frequency, the number of stock transported, the district of origin and destination and Euclidean distance traveled. Social network analysis was used to characterize the connections made between regions and districts as a result of cattle movement transactions, and to show how these characteristics might influence disease spread. Throughout 2005 a total of 1.3 million movement events involving 32 million head of cattle (equivalent to approximately 57% of the national herd) were recorded in the SGS database. The greatest number of farm-to-farm movements occurred from April to June whereas numbers of farm-to-slaughter movement events were relatively constant throughout the year. Throughout 2005 there was a 1.1-1.6-fold increase in the number of farm-to-farm movements of cattle during April-June, compared with other times of the year. District in-degree and out-degree scores varied by season, with higher maximum scores during the autumn and winter compared with summer and spring. Districts with high in-degree scores were concentrated in the Finishing region of the country whereas districts with high out-degree scores were concentrated not only in the Finishing region but also in Mesopotamia, eastern Border and southern Central regions. Although movements of cattle from the Border region tended not to be mediated via markets, the small number of districts in this area with relatively high out-degree scores is a cause for concern as they have the potential to distribute infectious disease widely, in the event of an incursion.

  2. Summary of CRP participants' reports: Argentina

    International Nuclear Information System (INIS)

    The activities of the Argentinean research group participating in the CRP can be briefly summarized in the following items: - Implementation of algorithms to extract dynamical features of the liquid and solid motion in multiphase systems. Particularly, analysis of radioactive tracer trajectories moving freely in 3D mock-ups of different multiphase reactors. - Development and implementation of algorithms capable of classifying flow regimes and diagnosing flow regime transitions in multiphase contactors, particularly bubble columns, three-phase fluidized beds and circulating fluidized beds. - Development, mounting and implementation of a Computer Automated Radioactive Particle Tracking (CARPT) facility in Argentina in collaboration with a group of the National Commission of Atomic Energy (CNEA). Multiphase systems are ubiquitous in industrial practice, either in pipes, operation units and multiphase reactors (MPR). MPR are vessels where two or more phases are brought together for a chemical transformation to take place. They are extensively used for quite diverse applications ranging from the upgrading and conversion of petroleum feed-stocks, with a huge installed capacity, to the manufacture of pharmaceuticals or fine-chemicals, and ever present in biotechnological processes. The gamma emission tomography of a single radioactive tracer, frequently called Computer Automated Radioactive Particle Tracking (CARPT), provides a massive amount of information on the traced phase motion, which has been used to determine characteristic features, like Eulerian velocity fields, turbulence intensities, dispersion coefficients, phase distribution, etc. The fluid dynamics in MPR is extremely complex due to interaction of the coexisting phases, particularly for fluidized systems or gas-liquid systems at high gas velocities. Moreover, these systems dynamics frequently have chaotic features and are far from being understood. Hence, further insights on fundamentals of the motions are

    The literature on IQ gains in Latin America is sparse. We estimate gains on Raven's Progressive Matrices in the city of La Plata (Argentina) between 1964 and 1998. The gains are robust at the top of the curve as well as at the bottom. Therefore, they are contrary to the hypothesis that nutrition played a major role in recent Argentine IQ gains.…

    2013-08-01

    Full Text Available The recent Escherichia coli epidemic in Germany gave a lesson at an international level. There is no time to solve food security problems when an epidemic is on the way. The epidemic in Germany exposed the fissures in the control systems of the Federal Risk Evaluation Institute of this country, as well as showing the incompetency of health authorities, who had great difficulty in resolving the situation. To summarize, the possibility of prevention was confused with the utopian idea of non-occurrence. It was not less important the public’s recognition and the “awakening” of health ministers in the European Union as regards the proven fact that pathogenic and even lethal microorganisms may be present in the food we eat. Argentina has the highest incidence of hemolytic uremic syndrome in the world, and the next epidemic is likely not to occur in Germany, but in any other country, such as Argentina. In order to avoid complicity, we do not wish to remain silent about the situation in Argentina. Therefore, this is the writer’s motive for writing this article, which describes the scientific advances and the ethical pitfalls related to a disease transmitted by food, particularly hemolytic uremic syndrome, in Argentina.

  2. Horticulture in Argentina: a productive alternative with great potential

    2011-12-01

    Full Text Available Horticulture in Argentina is an activity with great potential whose history has mainly been driven by Italian immigrants who arrived during the last two centuries. It is a valuable complement for traditional primary productions on which the country is focused with more than 30 millions of cultivated hectares and different agro-climatic conditions that characterize the different horticultural regions distributed throughout the country. The aim of this article is to give a panorama of the history, reality and perspectives in Argentina of an activity that is an opportunity for producers and entrepreneurs interested in it. Due to its characteristics, horticulture generates and dynamizes employment with great importance for regional economies. The proportion between vegetables and fruit produced and commercialized in Argentina is 63 and 34% respectively. Horticultural products for exportation largely are garlic, onion and beans. Concerning the most commercialized vegetables in Argentina, potato, tomato, onion, squash, lettuce, pepper, marrow and sweet potato stand out, whereas orange, tangerine, apple, banana, lemon, pear, grape and grapefruit may be highlighted among fruit. At present, the main challenge of the Argentinian horticultural sector is given not only by the possibilities of productive diversification and the expansion of the productive area but also of the technological level optimization, the application of quality norms and the agro-industry growth.

    The Order Siphonaptera comprises cosmopolitan haematophagous ectoparasites of birds and mammals. More than ten years have past since the last list of species known for Argentina. Herein we provide a review of the fleas from the country, which includes an updated list, host species and geographical distribution for each taxa, as well as some comments. We report 127 species and subspecies belonging to eleven different families; 42 of these species are endemic. Four genera (Adoratopsylla, Cleopsylla, Ctenidiosomus, and Nonnapsylla) and six species and subspecies (Adoratopsylla (Adoratopsylla) antiquorum antiquorum, Agastopsylla pearsoni, Polygenis (Polygenis) roberti beebei, Plocopsylla (Plocopsylla) silewi, Plocopsylla (Plocopsylla) wilesi and Tunga terasma) are added to the list for Argentina. Nine species new to science are included, described on the bases of specimens collected from Argentina (Ctenidiosomus austrinus, Ectinorus (Ectinorus) lareschiae, Ectinorus (Ectinorus) spiculatus, Ectinorus (Ectinorus) morenoi, Hectopsylla narium, Plocopsylla (Plocopsylla) linardii, Neotyphloceras crackensis, Neotyphloceras pardinasii and Tunga perforans). Information provided herein contributes to the knowledge of the fleas from Argentina, necessary to a better understanding of their role as parasites themselves and vectors of zoonotic importance.

    2013-01-01

    Full Text Available En los sistemas agrarios, los riesgos asociados al clima definen la actividad productiva por estar directamente vinculada a los procesos naturales. Este trabajo se centra en uno de los aspectos considerados como central en el manejo de los riesgos climáticos en los entornos agrícolas, el de la percepción social que los actores tienen de dichos riesgos (variabilidad o eventos extremos e incluso normali- dad. Esta percepción respondería en primer término a la influencia de diferentes procesos socio-históricos en los que participaron (circunstancias económicas dependientes del contexto internacional y nacional, además de los cambios registrados en el clima en los últimos tiempos que influyeron en las condiciones físicas preexistentes. Dicha percepción se plasmó en modificaciones productivas en Río Segundo (provincia de Córdoba, Argentina, al incorporar la tecno- logía del riego. La principal estrategia puesta en marcha por estos productores, tomados como caso de estudio, para enfrentar el principal riesgo climático (la inestabilidad y escasez de lluvias, es la aplicación de riego complementario por pivotes centrales con agua subterránea. Los datos con- cretos disponibles sobre las precipitaciones no justificarían la incorporación del riego. Sin embargo, si lo hace la resignificación del riesgo de escasez de precipitaciones que han hecho estos productores “de punta”, al considerarla como algo inaceptable en la actividad agrícola moderna.

  9. Small mammal distributional patterns in Northwestern Argentina

    Full Text Available ABSTRACT Quantitative evaluations of species distributional congruence allow evaluating previously proposed biogeographic regionalization and even identify undetected areas of endemism. The geographic scenery of Northwestern Argentina offers ideal conditions for the study of distributional patterns of species since the boundaries of a diverse group of biomes converge in a relatively small region, which also includes a diverse fauna of mammals. In this paper we applied a grid-based explicit method in order to recognize Patterns of Distributional Congruence (PDCs and Areas of Endemism (AEs, and the species (native but non-endemic and endemic, respectively that determine them. Also, we relate these distributional patterns to traditional biogeographic divisions of the study region and with a very recent phytogeographic study and we reconsider what previously rejected as 'spurious' areas. Finally, we assessed the generality of the patterns found. The analysis resulted in 165 consensus areas, characterized by seven species of marsupials, 28 species of bats, and 63 species of rodents, which represents a large percentage of the total species (10, 41, and 73, respectively. Twenty-five percent of the species that characterize consensus areas are endemic to the study region and define six AEs in strict sense while 12 PDCs are mainly defined by widely distributed species. While detailed quantitative analyses of plant species distribution data made by other authors does not result in units that correspond to Cabrera's phytogeographic divisions at this spatial scale, analyses of animal species distribution data does. We were able to identify previously unknown meaningful faunal patterns and more accurately define those already identified. We identify PDCs and AEs that conform Eastern Andean Slopes Patterns, Western High Andes Patterns, and Merged Eastern and Western Andean Slopes Patterns, some of which are re-interpreted at the light of known patterns of the

    The International Atomic Energy Agency (IAEA) is creating a database of information on radioactive discharges to atmospheric and aquatic environments from nuclear and radioactive installations, and from facilities using radionuclides in medicine, industry and research. The database is expected to facilitate the analysis of worldwide trends in discharge levels and provide a basis for assessing the impact of the discharges on humans and on the environment. In November 2002 took place the first meeting of national contact points and the Nuclear Regulatory Authority (ARN in Spanish) was present as the counterpart for the provision of discharge data from Argentina. This paper, presented in the above mentioned meeting, is a general overview of the radioactive discharges control in Argentina including the legal infrastructure, the population dose assessment methodology and the main characteristics of the facilities in the country with radioactive discharges to the environment.

    Despite its great wind endowment, Argentina has not still succeeded in increasing wind power share in its wholesale market. However, the energy supply problem that this country is facing from 2004 on seems to open an opportunity for wind energy projects. A wide range of legislation has recently emerged. In this context, this paper discusses whether policy instruments in the Argentinean regulatory frame contribute to economic feasibility for wind power projects or not. To this purpose, we study wind installed capacity, Argentinean wind potential, the different promotion tools used worldwide and those employed in Argentina. Finally, we realize a feasibility study for a typical project. We found, that in spite of its high wind potential, economic feature, related to policy instruments, have been a boundary to the development of wind energy into the energy mix. (author)

    Bunyamwera virus (BUNV) (Bunyaviridae, genus Orthobunyavirus, serogroup Bunyamwera) is considered an emerging pathogen for humans and animals in American countries. The CbaAr-426 strain of BUNV was recovered from mosquitoes Ochlerotatus albifasciatus (Diptera: Culicidae) collected in Córdoba province (Argentina), where serological studies detected high seroprevalences in humans and animals. Molecular detection of Orthobunyavirus was performed in mosquitoes collected in Córdoba province. Seventeen mosquito pools of Oc. albifasciatus, Ochlerotatus scapularis and Culex quinquefasciatus (Diptera: Culicidae) showed positive results; four of these positive pools, all of Oc. scapularis, were sequenced. All amplicons grouped with BUNV in the Bunyamwera serogroup. The findings highlight the circulation of BUNV in Córdoba province and represent the first report of BUNV-infected Oc. scapularis mosquitoes in Argentina. PMID:25991544

    This study examined whether healthier family dynamics were associated with higher personal strengths of resilience, sense of coherence, and optimism among dementia caregivers in Argentina. Caregivers are usually required to assist individuals with dementia, and family members have typically fulfilled that role. Personal strengths such as resilience, sense of coherence, and optimism have been shown to protect caregivers from some of the negative experiences of providing care, though the family-related variables associated with these personal strengths are largely unknown. Hierarchical multiple regressions investigated the extent to which family dynamics variables are associated with each of the caregiver personal strengths after controlling for demographic and caregiver characteristics. A sample of 105 caregivers from Argentina completed a set of questionnaires during a neurologist visit. Family dynamics explained 32% of the variance in resilience and 39% of the variance in sense of coherence. Greater family empathy and decreased family problems were uniquely associated with higher resilience. Greater communication and decreased family problems were uniquely associated with higher sense of coherence. Optimism was not found to be significantly associated with family dynamics. These results suggest that caregiver intervention research focused on the family may help improve caregiver personal strengths in Argentina and other Latin American countries. PMID:27413574

The objective of the workshop series is to conduct a systematic evaluation of the roles played by U.S. nonproliferation policy in cases of nuclear rollback or restraint and to provide recommendations for future nonproliferation efforts based on lessons learned. Key attendees at the workshop included officials and former officials from the foreign ministries of Argentina and Brazil, and current and former officials from the U.S. Department of State, the Arms Control and Disarmament Agency (ACDA), and the Department of Energy (DOE). Scholars and independent researchers who have examined nuclear policy in Argentina and Brazil also participated. This workshop report includes important background information that helps set the stage for assessing nuclear policies in Argentina and Brazil. It describes national perspectives and areas of consensus and debate among the participants, particularly on the questions of lessons learned and their salience to proliferation challenges in other states. It also summarizes key questions and propositions regarding the roles played in these cases by U.S. nonproliferation policy.

    Full Text Available Peronismo e anti-peronismo definiram o padrão da rivalidade Brasil-Argentina no contexto do início da guerra fria. Inúmeros documentos diplomáticos brasileiros – ofícios, despachos, memorandos, telegramas – datados dos anos de 1946 a 1948 apresentavam em seus títulos temas como “infiltração argentina no Sul do Brasil”, “expansionismo político da Argentina”, “política expansionista da Argentina”, etc. Pode-se afirmar que o anti-peronismo consolidou-se em setores dirigentes do país, por meio de uma política que ultrapassava, de algum modo, o próprio peronismo. Por exemplo, a ideia de que a Argentina procurava expandir sua área de influência na América do Sul remonta, pelo menos ao período anterior a segunda grande guerra. Assim, a identificação da forma como se construiu o anti-peronismo no Brasil permite avaliar mais especificamente que interesses e quais setores alimentaram visões contrárias ao diálogo bilateral.

    Full Text Available RESUMEN. Las Trechini constituyen una tribu de Carabidae distribuida ampliamente en la región Andino Patagónica. A pesar de que existen varias revisiones parciales de esta tribu para la Argentina y Chile, es muy común hallar especies nuevas, debido sobre todo a la prospección de áreas no exploradas. En este aporte se describe una especie nueva del género Trechisibus Jeannel del Cerro Nevado (Mendoza, Argentina. Por sus características morfológicas pertenece al grupo de especies depressus. Se describe e ilustra el adulto de esta especie nueva, se provee una clave para la identificación de las especies del grupo depressus y se discuten algunos aspectos de la distribución de estas especies.ABSTRACT. Trechini is a tribe of Carabidae (Coleoptera widely distributed in the Andean Patagonian region in South America. In spite of several partial revisions of the tribe for Argentina and Chile, it is very common to find new species due to the research of unexplored areas. In the present paper, a new species of the genus Trechisibus Jeannel from the Cerro Nevado (Mendoza, Argentina is described. Based on its morphological features the new species is considered as a member of the depressus group. The adult of the new species is described and illustrated, a key for the identification of the species of the depressus group is provided, and some aspects of the distribution of the group are discussed.

    Full Text Available A pesar de la presencia de Aëdes aegypti en el municipio de Rosario -República Argentina - no se han notificado casos de Dengue autóctono. Esta condición y otras características, que convierten a la ciudad vulnerable para el desarrollo de la enfermedad, brindan, en contrapartida la posibilidad de intervenir para prevenirla, como pocas veces ofrecen los problemas de salud comunitaria. El Sistema Municipal de Epidemiología definió en el marco de un proceso intersectorial y coparticipativo entre Estado y Comunidad, acciones de promoción y prevención dirigidas a lograr la cooperación efectiva de la población en la eliminación de criaderos potenciales del vector. Se inició así en el año 2000, un proceso, con diversos grados de intervención estatal, centrando el trabajo en la acción de promotores domiciliarios, que acercaron conocimientos a los ciudadanos sobre el Dengue y su vector transmisor. Se recabó, además información para evaluar el riesgo asociado a la presencia de criaderos. La actividad se extendió a establecimientos educacionales y organizaciones barriales. Se promovieron, también, actividades intersectoriales concretas de limpieza y ordenamiento ambiental. La evaluación de dichas intervenciones, permitió verificar el perfeccionamiento de los conocimientos de la población mediante la promoción personalizada y posibilitó apreciar que se lograron mejores resultados con la incorporación de las escuelas y con las intervenciones realizadas con amplia participación estatal. Este trabajo puso en evidencia la necesidad del rol del Estado como incentivador y organizador de actividades para modificar actitudes e incorporar comportamientos responsables y solidarios de los ciudadanos, que aporten a las estrategias saludables.In spite of the presence of the Aëdes aegypti in the city of Rosario -Argentina- there is no evidence of reports of autochthonous Dengue.

    Full Text Available This paper aims to analyse the migration issues in Argentina, as they are perceived through the lenses of the European Union. Argentine society has faced capital changes in the past twenty years, going from a militarist regime to market economy and liberal democracy. All these have culminated with a profound economic crisis at the beginning of the years 2000, changing perceptions and creating new social patterns. Even though Argentine was since its creation a nation of immigrants, in the latest years this has become a sensitive issue. Deteriorating economic factors gave birth to an anti-immigration wave and to an emigration phenomenon.

    The peat bogs and peat deposits of Argentina are briefly described, with emphasis on the island of Tierra del Fuego, where the vast majority of the bogs are concentrated, due to environmental and climatic conditions. The Fuegian bogs are a source of peaty materials, presently used in soil-improving techniques. Further studies are needed to establish other technological possibilities. From the scientific point of view, the Fuegian bogs are outstanding palaeoclimatic and palaeoenvironmental data banks, due to their uninterrupted continuity since Late Glacial times and their exceptional pollen record and subfossil wood remains.

    Soybean biomass for biodiesel, produced in Argentina amongst other places, is considered by some to reduce greenhouse gas emissions and mitigate climate change when compared with fossil fuel alternatives. To ensure that the production of biofuels is 'sustainable', EU institutions and national governments are designing certification schemes for the sustainable production of biomass. In this paper, we question the validity of these proposed environmental standards, using the production of Argentine soybean as a case study. We highlight the negative environmental and social impacts of intensive soybean production, and conclude that certification schemes are unlikely to be able to address the detrimental impacts of increased biofuel production and trade.

    A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Toxocara cati, Toxascaris leonina, Ancylostoma caninum, Ancylostoma tubaeforme and Uncinaria stenocephala. In addition, new hosts are reported for 6 nematode species and 5 helminth species are recorded for the first time in Argentina: Aonchotheca putorii, Molineus brachiurus, Cyathospirura chevreuxi, Physaloptera praeputialis and Oncicola martini.

    The growing popularity of cognitive-behavioral therapy (CBT) has helped reshape the mental health scene in the city of Buenos Aires, historically the stronghold of psychoanalysis. In the early 1980s, CBT was infrequently used and sometimes overtly resisted in the field of mental health. Almost 3 decades later, the impact of CBT has increased dramatically in Argentina, not only in independent practice but also in the health system and in everyday life. This article aims to describe the process by which Argentine psychotherapists first adopted this new theoretical framework. PMID:26120921

    donde aparecía la Hipertensión Arterial ocupando el primer lugar. CONCLUSIÓN: La introducción del "ITEM 33" en el Certificado de Defunción de la Provincia de Santa Fe produjo modificaciones importantes en los datos sobre MM. Estas modificaciones pueden ser atribuidas a la disminución del subregistro, ya que no se encuentran razones valederas para pensar en un aumento real en la ocurrencia de muertes maternas. Por lo cual se concluye que: este instrumento de recolección de datos permitiría corregir el subregistro y obtener datos de mayor calidad que, en consecuencia, posibiliten la implementación de políticas y programas de salud basados en datos que reflejen la verdadera situación sanitaria.INTRODUCTION: Maternal Mortality (MM shows differences in population health and life conditions, therefore it becomes not only a good socioeconomic indicator but also an indicator of health service providers and health care service quality in the assistance to women at reproductive age. Official Health Statistics do not reveal the size of MM problem due to the under-report that has this death cause. This deficiency or lack of data is highly marked especially in underdeveloped countries. It has been estimated that Argentina is not out of this under-report problem. In 1994, the Province of Santa Fe decided to add a specific ITEM to the Death Certificate for Maternal Death cause with the aim of amending the under-report. OBJECTIVES: The main objective of this study was to evaluate changes that Maternal Mortality Ratio (MMR registered between 1988 and 2001 as a consequence of adding the "33 ITEM" regarding Maternal Death to the Death Certificate of the Province of Santa Fe from 1995 on. MATERIAL AND METHODS: Bibliography was reviewed as regards the MM under-report. The MM occurrence in the Province of Santa Fe was studied from 1988 to 2001. Changes produced by the 33 ITEM appearance in the Death Certificate of the Province of Santa Fe during the period 1995 - 2001 were

  11. Market Report : The air pollution control market in Argentina

    International Nuclear Information System (INIS)

    This report presents some facts about how Canadian companies can work within the many innovative programs designed by the Canadian federal government to facilitate the export of Canadian products and services into the Argentine air pollution control market. As the economy stabilizes in Argentina, more effort is being given to issues of environmental protection and the Argentine government is increasing funding on environmental programs. The country is also strengthening its environmental legislation and increasing enforcement. The Kyoto and Montreal Protocols have brought attention to air quality issues such as climate change, emissions trading, and ozone depleting substances. Several initiatives currently focus on air quality monitoring and data collection since much information has to be gathered on air pollution levels. Emission control equipment for chemical, petrochemical, mining and power sectors are the best prospects for air pollution control, along with monitoring equipment, consulting services and fuel conversion equipment for vehicles and industrial plants. It was noted that there are legal and practical difficulties regarding new contract negotiations in Argentina, particularly with the decline in credit availability. This paper outlined the key factors shaping market growth. Most opportunities lies with projects funded by international financial institutions. The report includes a section on international competition, and the Canadian position for both private- and public-sector companies. A section on market logistics focused on issues such as direct sales, import regulations, and export credit risks. It is recommended that companies interested in the Argentine market contact the Embassy in Buenos Aires for information. refs., tabs

    In the world, hereditary angioedema (HAE) affects 1 every 50000 persons. It is characterized by highly disabling and recurrent episodes of cutaneous, abdominal and laryngeal episodes of angioedema. Asphyxia related mortality ranges from 15 to 50%. In Argentina a plasma derived C1 inhibitor concentrate (pdC1INH) has been available for the treatment of acute attacks for many decades, however, only15 (26%) out of 58 patients had received pdC1INH at least once until 2008, and only2 (3.4%) had used it regularly. After worldwide approval of the new drugs for the treatment of acute HAE attacks, adding icatibant to pdC1INH in Argentina, and after publication of the therapeutic guide for the country, 42 (82%) out of 51 patients from the original group has pdC1INH available to treat their next attack. However, 16 (18%) patients continue without access to medication and other 15 (35.7%) obtain their therapy spuriously through some other affected relative in their environment. Only 12 (28.6%) patients of the group self-treated at home. Access to treatment has greatly improved, but needs to be extended to all patients and self-treatment at home should be encouraged.

    The present study is focus on the final energy balance of bioenergy production in Argentina using soybean, sunflower, rapeseed, corn and sorghum as feedstocks. The balance considers the difference between the energy contained per unit and the amount used for its generation in all the different steps from sowing to final destination. For direct energy consumption Costo Maq software was employed using local fuel consumption forecast for each field labor. Particular attention is paid to the energy consumption in the agricultural steps considering the distinctive no till system spread out in Argentina that has a very low energy input. Direct and indirect energy were considered in the different steps of bioethanol and biodiesel generation. Industrial conversion consumption was based on international literature data. Comparisons were made between tilled and no till practices and considering or not the energy contained in co products. Results indicate a balance ranging from 0.96 to 1.54 not considering the co products. If co products were introduced the balances ranged between 1.09 and 4.67. (author)

    Pappophorum vaginatum is the most abundant C4 perennial grass desirable to livestock in rangelands of northeastern Patagonia, Argentina. We hypothesized that (1) defoliation reduce net primary productivity, and root length density and weight in the native species, and (2) root net primary productivity, and root length density and weight, are greater in P. vaginatum than in the other, less desirable, native species (i.e., Aristida spegazzinii, A. subulata and Sporobolus cryptandrus). Plants of all species were either exposed or not to a severe defoliation twice a year during two growing seasons. Root proliferation was measured using the cylinder method. Cylindrical, iron structures, wrapped up using nylon mesh, were buried diagonally from the periphery to the center on individual plants. These structures, initially filled with soil without any organic residue, were dug up from the soil on 25 April 2008, after two successive defoliations in mid-spring 2007. During the second growing season (2008-2009), cylinders were destructively harvested on 4 April 2009, after one or two defoliations in mid-and/or late-spring, respectively. Roots grown into the cylinders were obtained after washing the soil manually. Defoliation during two successive years did reduce the study variables only after plants of all species were defoliated twice, which supported the first hypothesis. The greater root net primary productivity, root length den-sity and weight in P. vaginatum than in the other native species, in support of the second hypothesis, could help to explain its greater abundance in rangelands of Argentina.

    2006-12-01

    There are 29 medical schools in Argentina (this number has increased rapidly in the last decade) offering a 6-year curriculum that usually consists of 3 years of basic science, 2 years of clinical sciences, and one internship year. Annually, 5,000 physicians graduate from these programs. Admission requirements vary depending on each university's policy. Some do not have entry requirements; others require a course, usually on the basics of mathematics, biology, chemistry or physics, and some introduction to social and humanistic studies. Each year, there are approximately 12,000 first-year medical students attending the 29 schools, which suffer a high dropout rate during the first years because of vocational problems or inability to adapt to university life. Some schools have massive classes (over 2,000 students), which makes it difficult for the schools to perfect their teaching. The number of full-time faculty members is low, and some of them have appointments at more than one medical school. Residency programs offer an insufficient number of places, and fewer than 50% of the graduates can obtain a residency position because of strict admission requirements. Coordination between the Ministry of Health, representing the health care system, and the Ministry of Education, representing the medical education system, needs to be improved. Despite the problems of medical education in Argentina, the movement to improve the education of health care workers is growing. The author offers two recommendations to help accomplish this goal.

  18. Conservative litigation against sexual and reproductive health policies in Argentina.

    Peñas Defago, María Angélica; Morán Faúndes, José Manuel

    2014-11-01

    In Argentina, campaigns for the recognition of sexual and reproductive rights have sparked opposition through litigation in which the dynamics of legal action have come from self-proclaimed "pro-life" NGOs, particularly since 1998, when the conservative NGO Portal de Belén successfully achieved the banning of emergency contraception through the courts. The activities of these groups, acting as a "civil arm" of religion, are focused primarily on obstructing access to legally permissible abortions and bringing about the withdrawal of a number of recognized public policies on sexual and reproductive health, particularly the 2002 National Programme for Sexual Health and Responsible Procreation. This paper analyzes the litigation strategies of these conservative NGOs and how their use of the courts in Argentina has changed over the years. It gives examples of efforts in local courts to block individual young women from accessing legal abortion following rape, despite a ruling by the National Supreme Court of Justice in 2012 that no judicial permission is required. In spite of major advances, the renewed influence of the Catholic hierarchy in the Argentine political scene with the accession of the new Pope poses challenges to the work by feminists and women's movements to extend and consolidate sexual and reproductive rights.

    Tartaglione, Aureliano; Blostein, Jerónimo; Cantargi, Florencia; Marín, Julio; Baruj, Alberto; Meyer, Gabriel; Santisteban, Javier; Sánchez, Fernando

    We present here a short review of the main work which has been done in the latest years in neutron imaging in Argentina, and the future plans for the development of this technique in the country, mainly focused in the design of a new neutron imaging instrument to be installed in the future research reactor RA10. We present here the results of the implementation of the technique in samples belonging to the Argentinean cultural heritage and experiments related with hydrogen storage. At the same time, the Argentinean RA10 project for the design and construction of a 30 MW multipurpose research reactor is rapidly progressing. It started to be designed by the National Atomic Energy Commission (CNEA) and the technology company INVAP SE, both from Argentina, in June 2010. The construction will start in the beginning of 2015 in the Ezeiza Atomic Center, at 36 km from Buenos Aires City, and is expected to be finished by 2020. One of the main aims of the project is to offer to the Argentinean scientific and technology system new capabilities based on neutron techniques. We present here the conceptual design of a neutron imaging facility which will use one of the cold neutron beams, and will be installed in the reactor hall. Preliminary simulation results show that at the farthest detection position, at about 17 m from the cold source, a uniform neutron beam on a detection screen with an intensity of about 108 n/cm2/s is expected.

    Full Text Available The paper analyzes innovative psychiatric practices that took place in Argentina during the sixties and seventies at the Hospital Jose Esteves in the province of Buenos Aires. Objective: To present the coexistence of different paradigms related to mental health in the same institution and to analyze the complexities generated by this scenario. Methodology: This study uses primary sources in the form of medical records of patients admitted to the hospital between 1960 and 1979. The medical records were cross-referenced with publications of newspapers and magazines of the time. Results: The analysis shows that the political environment during the era of military dictatorship —characterized by ideological persecution and the inhibition of political expression— influenced the development of innovative psychiatric practices. At the same time, instances of anti-Semitism and ideological persecution among health workers affected therapeutic approaches. Conclusions: While the introduction of innovative practices in mental health led to some resistance among the more orthodox psychiatrists, the presence of different paradigms shows a plan, both political and professional, to transform psychiatry and admission policy in Argentina.

O marco legal deste tipo de reformismo no sistema de educação superior argentino assenta-se na promulagação da Lei número 24.521, em 20.07.1995. Com o intuito de compreender as implicações das políticas públicas geradas no referido período para o conjunto das universidades argentinas, são apresentados dados e considerações sobre população estudantil, plantel docente, ingresso, evasão, graduação, dedicação exclusiva e o programa de incentivo aos professores pesquisadores.

    Full Text Available RESUMEN: En 1990, Argentina, Brasil, Uruguay y Paraguay firmaron el acuerdo de integración económica denominado Mercado Común del Sur o Mercosur. En la actualidad, Chile está negociando su inclusión del tipo "4+1" y se han iniciado conversaciones con el Pacto Andino y con México en el seno de la ALADI. Colominas destaca la importancia económica que para estos cuatro países ha supuesto la creación del Mercosur, así como que la integración regional puede superar el desarrollo excluyente de estas economías.ABSTRACT: In 1990, Argentina, Brazil, Paraguay and Uruguay signed an aggrement of economical integration denominated Mercado Común del Sur or Mercosur.

    Full Text Available La heterogeneidad de la estructura productiva en Argentina diferencia sectores con distinto grado de desarrollo tecnológico y posibilidades de acumulación. Esto pone en cuestión la visión ortodoxa de una estructura homogénea del capital y evidencia la necesidadde políticas específicas para cada sector. El llamado sector informal, compuesto principalmente por microempresas con escaso o nulo excedente, constituye uno de los sectores más vulnerables de la estructura productiva argentina. Por ello nos proponemos analizar el funcionamiento de este sector a partir de una encuesta realizada a 100 microempresas pobres de la zona sur de la Ciudad de Buenos Aires. Asimismo, a partir de los resultados obtenidos y de un análisis de las políticas públicas que repercuten sobre el sector, se realizan propuestas de políticas principalmente vinculadas a salir de la informalidad, mayor capacitación y financiamiento.

    Full Text Available La Argentina atraviesa una seria crisis educativa que se pone de manifiesto en la cantidad de personas educadas con las que cuenta así como en la calidad de los conocimientos que demuestran poseer quienes han pasado por el sistema educativo. Este trabajo se inicia con un análisis de la actitud social ante la educación, destacando la conformidad generalizada de los padres con la educación que reciben sus hijos. Paradójicamente, de acuerdo con todas las evaluaciones realizadas, aquella presenta graves deficiencias. Asimismo, se comentan resultados de estudios que demuestran una caída en la calidad de la educación, evaluada al completar la ensenanza media, en el lapso comprendido entre 1970 y 1995. Después de establecer comparaciones con la situación de otros países, se formulan algunas observaciones generales en relación con el papel que desempeña la dirigencia social en la génesis y el mantenimiento de la crisis educativa que atraviesa el país. Superarla constituye una cuestión de trascendental importancia para el futuro, no sólo económico, sino también social y políticó de la Argentina

They finished the work of their predecessors, especially that of the late Huidobro, who, after Altazor left the more external aspects of the play behind, and of César Vallejo, creating a poetic area where emotion and subjectivity coexist with linguistic experimentation, where the pleasure of construction and the subtleties of linguistic deformations are inexorably tied to sentiment.In obliterating the distance between I and You, their poetry abandons the passage between different textual practices and gives space to an inter-subjectivity that leads the reader to forget his passivity and become active in sensory production.Keywords: avant-garde, Argentine poetry, the Sixties, linguistic experimentationITJuan Gelman, Leónidas Lamborghini, Francisco Urondo, César Ferández Moreno, fra i nomi più noti della generazione poetica argentina degli anni Sessanta, riprendono la concezione di un’arte verbale critica che l’avanguardia ispanoamericana aveva proposto come prioritaria. Completano il lavoro dei suoi predecessori, soprattutto dell’ultimo Huidobro, che dopo Altazor abbandona gli aspetti più esterni del gioco, e di César Vallejo, creando uno spazio poetico dove l’emozione, la soggettività, coesistono con la sperimentazione del linguaggio, dove il piacere della costruzione, delle sottigliezze delle deformazioni linguistiche sono indissolubilmente legate al sentimento.La loro poesia, nell’abolire la distanza fra Io e Tu, lascia aperto il passaggio fra le pratiche testuali differenti e dà spazio a un’intersoggettività che induce il lettore ad abbandonare la sua passività e a diventare attivo nella produzione del senso.Parole chiave: avanguardia, poesia argentina

    Full Text Available The very limited of political science analysis on tourism is explained by the primacy of the economic outlook that conceives tourism phenomenon as a simple consumer activity linked to private sector. However, political science is a cornerstone for understanding tourism, provides concepts and methodological tools that enhance the study of tourism. From this approach, we analyze the evolution of Argentina tourism policy taking as a reference production models economic-tourist. In this sense, we identify the main functions that takes tourism as a public issue in the country determined by the evolution of a social, economic and political context, which is structured according to existing international patterns. We point out the existence of an economic development model based on tourism.

  15. Electricity reform in Argentina: Lessons for developing countries

    Energy Technology Data Exchange (ETDEWEB)

    Pollitt, Michael [Judge Business School and ESRC Electricity Policy Research Group, University of Cambridge (United Kingdom)

    2008-07-15

    Argentina was one of the first countries in the world to implement a comprehensive reform of its electricity sector. Among developing countries only Chile has had a comparably comprehensive and successful reform. This paper traces the history of the Argentine reform, which began in 1992, and assesses its progress and its lessons. We conclude that the reform was very successful prior to the collapse of the Argentine peso in early 2002. We suggest lessons for the generation, transmission and distribution (and retailing) sectors, as well as the economic regulation of electricity and the general institutional environment. We note that the achievements of the sector have been severely strained by the government's poor energy policy since the crisis. (author)

    Previously treated as species of Pseudalopex, Argentine members of the genus Lycalopex (L. griseus, L. gymnocercus, and L. culpaeus) are examined to clarify the taxonomic status of each named form. Principal components analyses of 26 cranial measurements of 151 adult specimens and 11 pelage characters of 111 specimens, clearly distinguish L. culpaeus from the other two taxa. Lycalopex griseus and L. gymnocercus show clinal variation in cranial measurements and pelage characters. Qualitative cranial characters, used as diagnostic for L. griseus and L. gymnocercus, revealed great nongeographic variation. We conclude that L. griseus and L. gymnocercus are conspecific, and should be known as L. gymnocercus. Therefore, we recognize only two species of the genus Lycalopex (L. culpaeus and L. gymnocercus) in Argentina. We also use this opportunity to review synonymies of the recognized species of Lycalopex.

    Full Text Available The extent of freshwater biological invasions is difficult to predict. The thermophilic Daphnia lumholtzi Sars, 1885 (Cladocera: Daphniidae has successfully invaded a large section of temperate North America from an Old World source, damaging ecosystems and fisheries. The species was later reported introduced into Mexico and Brazil. Here we report D. lumholtzi in Argentina - the most southerly record in the New World for this species. Our genetic analyses establish haplotype identity with North American specimens, consistent with the colonization of South America from North America. The detection dates of the records in South America and the association with the Paraná River, provide evidence that river ways play a role in expansion of D. lumholtzi. The invasion of D. lumholtzi has now reached a similar wide latitudinal span to the distribution in the Old World.

  19. Infrastructure Upgrade Experience of Station IS02, Ushuaia, Argentina

    International Nuclear Information System (INIS)

    Full text: IS02 infrasound station is located 100 km from Ushuaia city, Argentina. It became operational in April 2005, but due to flooding of the vaults all of them were reinforced in January 2006. The station was certified in August 2006. After two years new problems with water filtration appeared at the station, making it extremely necessary to update its infrastructure. From the station operator's point of view, the new design of the station sites proved to be successful since no water problems appeared in the vaults and pipes of all of them. The graphs show the improvement in the signal in one of the arrays before and after the 2010 infrastructure upgrade. The efforts made by PTS and Station Operator (ARN) allowed the achievement of the planned goal, resulting in a better behavior of the station since the works described in this poster were carried out.

  3. Rehabilitation of oiled magellanic penguins (Spheniscus magellanicus) in Patagonia, Argentina

    International Nuclear Information System (INIS)

    On September 10, 1991, the International Bird Rescue Research Center (IBRRC) was contacted by Dee Boersma, professor of zoology at the University of Washington. An oil spill from an unknown source had affected large numbers of magellanic penguins (Spheniscus magellanicus) returning to breeding colonies along the coast of southern Argentina. Dr. Boersma had been studying the penguins at Punta Tombo since 1982. It wasn't unusual for some of the penguins to arrive oiled, but this year the numbers of oiled birds were up considerably. In the week of September 14 to 20, a survey of 239 kilometers of coastline (about one-third of the affected area) spotted 16,350 penguins with some degree of oiling

    The present paper discusses wind and wind power characteristics in a region north of 40{sup o}S (North Patagonia, Argentina) as well as wind power projects sustainability. Extreme wind episodes influence most economic and social regional activities. Mean flow pattern was studied in three North Patagonia sites: Neuquen, Mari Menuco and Cutral-Co, by sampling analysis of wind direction and intensity during a year. Gusts were quantified and strong winds were studied. Available meteorological power was also estimated. It was observed that North Patagonia is a place of great wind power potential. However, the energy available, which is related to prevailing strong winds, is also associated to high gust occurrence which certainly restricts exploitation. (Author)

    2016-06-01

    Full Text Available Abstract Traditionally, Argentine foreign policy has been regarded as the domain of the executive, and a laudable expression of realism. Perspectives that include domestic variables as a source of foreign policy have only emerged relatively recently, and have only assumed importance in a redemocratised Argentina in the course of its recurrent economic and political crises in the late 20th and early 21st century. This dynamic was particularly marked during and after the crisis of 2001. As a result, Kirchnerist foreign policy was affected by a range of complex domestic factors. The aim of this article is to show how those factors drove the governments of Néstor and Cristina Kirchner, without abandoning executive primacy, to prioritise a neodevelopmental economic model, and combine them with an autonomous foreign policy which they believed to be the only way to meet the social demands of those affected by the neoliberal crisis.

Revista de la nueva generación (1923-1927 to show the ambivalent reception of the movement in the River Plate. The Argentinean reaction ranged from the celebratory tribute to the rejection, differently from the Spanish Ultraism, that admired the futurist motifs. We will also mention the Argentine painters who accused the influence of the Italian movement as well as another phenomena that allows us to speak of a “warm local adaptation” of the Futurism in the pages of Rovente (1924, a magazine published in Buenos Aires by Pietro Illari.

    2009-12-01

    Full Text Available This paper explores the issue of silence under the last military dictatorship in Argentina (1976-1983. Silence spread rapidly in Argentine society during the first years of the so called National Reorganization Process (PRN and it became crucial for the maintenance of the illegal regime, This silence was actually assured not only by the action of the military government, but also by the clear identification of the political and social forces with the aims and values of the Proceso. However, this prevailing silence and the resulting failure of the existing discourses to articulate the effects of the dirty war resulted in a temporal suspension of meaning within the reality of the PRN. Silence became then the instance that would finally put into question the apparently smooth functioning of the PRN and would force the emergence and constitution of a new social movement and a new language of human rights in the country.

    Bajada del Diablo is located in the Northern Patagonian Massif, Chubut, Argentina. The study area includes several circular structures found in Miocene olivine basalts of the Quiñelaf Eruptive Complex and in the Late Pliocene/Early Pleistocene Pampa Sastre conglomerates. An impact origin has been proposed for these circular structures. With the aim of further investigate the proposed impact origin, topographic, gravimetric, magnetic, resistivity, palaeomagnetic and electromagnetic surveys in two circular structures (`8' and `G') located in Pampa Sastre conglomerates and in basalts of the Quiñelaf Eruptive Complex were carried out. The new geophysical results support the hypothesis of an impact origin. However, the confirmation of such an origin through the findings of shock metamorphism evidences and/or the recovery of meteorites remains elusive.

    2011-01-01

    The arbuscular mycorrhizal fungal (AMF) communities from the Yungas forests of Argentina were studied. The AMF species present in the rhizosphere of some dominant native plants (one tree: Alnus acuminata; three herbaceous species: Duchesnea indica, Oxalis conorrhiza, Trifolium aff. repens; and one shrub: Sambucus peruviana) from two sites (Quebrada del Portugués and Narváez Range) of the Yungas forests were isolated, identified and quantified during the four seasons of the year. Twenty-two AMF morphotaxa were found. Spore density of some AMF species at each site varied among seasons. The genera that most contributed to the biodiversity index were Acaulospora for Quebrada del Portugués and Glomus for Narváez Range. High diversity values were observed in the Yungas forests, particularly in the spring (rainy season). We concluded AMF differed in species composition and seasonal sporulation dynamics in the Yungas forests. PMID:21415289

    Full Text Available We analyze the individual motives of political party affiliation as a central variable that help us to characterize the party affiliation as a practice and as belonging to a party organization. The study was conducted through questionnaires, and the sample was integrated by 428 citizens over 18 and under 65 years old, from Cordoba, Argentina. We propose a categorization of the motives of affiliation, inductively constructed, that recovers the theoretical conceptualization from the sociology of the organizations and the socio-cognitive psychology. Likewise, we analyze the relationship between the different affiliation motives, the party and electoral practices, and the perception of efficiency and importance that the affiliation has for the participants.

    2003-05-01

    Full Text Available The reform of secondary education has been a fundamental part of national educational policy in Argentina since the beginning of the 1990s. Along with the decentralization of responsibilities to provinces and a new structure of primary and secondary education, changes have affected the areas of curriculum design, teaching methods, teacher training, school management, and information and evaluation systems. This study describes the main policies on secondary education implemented during the last decade, including their objectives and rationales. Focusing on how the reform can be seen to relate to issues of access, quality and equity, the study presents an analysis of its implementation, and discusses some of its effects. We argue that political, economic and technical factors as well as the strategies chosen by the national government resulted in a limited implementation, and we highlight the need for considering more focused reform strategies, alternative models of teacher training, and a more active involvement of teachers.

    Background Physician-implemented interventions for smoking cessation are effective but infrequently used. We evaluated smoking cessation practices among physicians in Argentina. Methods A self-administered survey of physicians from six clinical systems asked about smoking cessation counselling practices, barriers to tobacco use counselling and perceived quality of training received in smoking cessation practices. Results Of 254 physicians, 52.3% were women, 11.8% were current smokers and 52% never smoked. Perceived quality of training in tobacco cessation counselling was rated as very good or good by 41.8% and as poor/very poor by 58.2%. Most physicians (90%) reported asking and recording smoking status, 89% advised patients to quit smoking but only 37% asked them to set a quit date and 44% prescribed medications. Multivariate analyses showed that Physicians’ perceived quality of their training in smoking cessation methods was associated with greater use of evidence-based cessation interventions. (OR = 6.5; 95% CI = 2.2–19.1); motivating patients to quit (OR: 7.9 CI 3.44–18.5), assisting patients to quit (OR = 9.9; 95% CI = 4.0–24.2) prescribing medications (OR = 9.6; 95% CI = 3.5–26.7), and setting up follow-up (OR = 13.0; 95% CI = 4.4–38.5). Conclusions Perceived quality of training in smoking cessation was associated with using evidence-based interventions and among physicians from Argentina. Medical training programs should enhance the quality of this curriculum. PMID:27594922

  1. Nuclear Activities in Argentina. A short Review. Part 2

    International Nuclear Information System (INIS)

    The second part of this historical review covers the 'industrial' period of nuclear energy in Argentina. The National Atomic Energy Commission (CNEA), after a feasibility study carried out by argentine experts, in 1968 signed a contract to build a nuclear power plant. This PHWR plant, Atucha 1, of 310 MWe was inaugurated in 1973 and it is still operating. The same year the CNEA signed a new contract to build a CANDU type plant of 600 MWe, Embalse, that was finally inaugurated in 1983. The construction of a third plant, Atucha 2 of 745 MWe also a PHWR, was started in 1980 but was arrested in 1994, when more than 80% was completed, and it is still waiting a political decision to reach completion. Within the development of the nuclear power program, a fuel element production plant for the Argentine power reactors was built by the CNEA and a heavy water production plant of 250 tons/year was inaugurated in 1993 in the southern province of Neuquen. A pilot spent fuel reprocessing plant was designed but its construction was not completed. At the same time, a pilot gaseous diffusion plant was constructed in order to produce enriched uranium for research reactors. The activities in the field of radioisotope and radiation applications were also intensive, mainly in nuclear medicine and food preservation. A facility to fabricate sealed sources was built to process the Co 60 produced by the Embalse power plant. Argentina was active in the export of nuclear facilities: CNEA built a complete nuclear research center in Peru, and the Argentine company INVAP built research reactors in Algeria and Egypt. The same company is now building a research reactor in Australia. (author)

  2. Atmospheric quality in Argentina employing Tillandsia capillaris as biomonitor

    International Nuclear Information System (INIS)

    The objective of this research was to evaluate the biondicator capacity of Tillandsia capillaris f. incana (Mez.), widely distributed in Argentina, in relation to the accumulation of heavy metals and to its physiologic response to air pollutants. A sampling area with a surface of 50,000 km2 was selected in the central region of the Republic Argentina. The area was subdivided in grids of 25 x 25 km being collected pools at T. capillaris in each one of the intersection points when this was present. Of each pool three subsamples were analyzed independently. Besides, for 20% of the points, quintupled samples were collected in order to analyze the variability inside the site. The content of Co, Cu, Fe, Ni, Mn, Pb, and Zn was determined by Atomic Absorption Spectrometry. The concentration of chemical-physiological parameters was also determined with the objective of detecting symptoms of foliar damage. Chlorophylls, phaeophytins, hydroperoxy conjugated dienes, malondialdehyde, and sulfur were quantified in T. capillaris. Some of these parameters were used for calculating a pollution index. Data sets were evaluated by one-way ANOVA, correlation analysis, principal component analysis, and mapping. Different patterns of geographical distribution were obtained for the different metals that allow to reflect the so much contribution of natural and anthropogenic emission sources. According to our results it can be inferred that Fe, Mn, and Co probably originated from the soil. For Pb, the highest values were in the mountainous area, which can be attributed to the presence of minerals that close contains Pb in granitic rocks. Ni showed origin mainly anthropogenic, with values a risen in places close to industrial centers. For Zn the highest values were in areas of agricultural development, as well for Cu, whose presence could be related to the pesticides employment. (author)

    The number of graduate programs in Optoelectronics in Argentina is scarce. The current Optics and Photonics Education Directory lists only three programs. One of them was launched in 2001 in the Facultad de Ingeniería (College of Engineering), Universidad de Buenos Aires (UBA). This was the first graduate program in the field, leading to a Master Degree in Optoelectronics. This decision arose from the demand of telecommunications industries and several estate- or private-funded research institutions working with us in the fields of lasers, optics, remote sensing, etc. A great bonus was the steady work, during several decades, of research groups in the College on the development of different type of lasers and optical non destructive tests and their engineering applications. As happened in many engineering graduate programs in Argentina at that time, few non full-time students could finish their studies, which called for 800 hours of traditional lecture-recitation classes, and the Master Thesis. In recent years Argentine Education authorities downsized the Master programs to 700 hours of blended learning and we redesigned the Graduate Optoelectronic Engineering Program to meet the challenge, dividing it in two successive one year programs, the first aimed at a professional training for almost immediate insertion in the labor market (called Especialización en Ingeniería Optoelectrónica), and the second (called Maestría en Ingeniería Optoelectrónica y Fotónica) aimed at a more academic and research target to comply with the UBA standards for Master degrees. The present work is a presentation of the new program design, which has begun in the current year.

El trabajo discute las principales interpretaciones sobre las características y naturaleza de este grupo, pone de relieve algunas de limitaciones de los enfoques más habituales sobre el tema, y sugiere de qué manera conceptualizarlo de forma productiva. Aunque el objeto de este trabajo es la elite económica, todo análisis de este actor supone a la vez una manera de concebir las características del sistema de poder y del entorno económico en el que se desenvuelve la acción de los hombres de fortuna. Por este motivo, este trabajo formula algunas consideraciones generales sobre las características del Estado (argentino y el capitalismo (pampeano, con el fin de precisar mejor qué tipo de elite económica dominó la producción rural y la economía argentina en el período de crecimiento exportador que se extendió desde la Independencia hasta la Primera Guerra Mundial.

El ensayo no aporta nueva evidencia empírica, sino una reflexión a partir de la literatura existente.

    Bovine brucellosis is a zoonotic disease spread worldwide. The infection in cattle is predominantly caused by Brucella abortus and is usually detected in pregnant females through abortions. The disease is endemic in Argentina; however, infection in humans is underestimated and often not reported. The prevalence of bovine brucellosis in countries bordering Argentina is quite variable: 0.04% in Uruguay, 10.20% in the north and 0.06% in the south of Brazil, 0.2% in Chile, 3.15% in Paraguay and 2.27% in Bolivia. In 1999, the Argentine National Control and Eradication Program was implemented. Its strategies include identification of vaccinated animals, compulsory vaccination with B. abortus S19 of 100% of 3- to 8-month-old females, negative serological tests before animal movements and categorization of farms in terms of their brucellosis status. The epidemiological surveillance in milk is performed through the milk ring test and the indirect ELISA. The result of a national brucellosis survey performed in 2004 indicates that 12.4% (95% CI: 10.89-14.0) of Argentine beef farms are seropositive to Brucella and that the apparent prevalence in cattle is 2.10% (95% CI: 1.90-2.40). The official serological diagnostic tests are as follows: buffered plate antigen test, as screening, serum agglutination test, 2-mercaptoethanol and fluorescence polarization assay, competitive ELISA, as confirmatory tests, and complement fixation test, as definitive test. Santa Fe and a district in Córdoba have 'Outstanding Plans'. Tierra del Fuego is a 'Zone free from bovine brucellosis'. One question arising when studying the Argentine situation is why the disease remains endemic if good regulations exist to control and eradicate it. In future, some different aspects might be evaluated to understand it, and further studies should be performed to prioritize, select and refine control strategies. PMID:23046031

    Full Text Available OBJECTIVE: to analyze the impact that caring has on a member of the family caring for a patient after a cerebrovascular accident, correlating life modifications and mental suffering with the perceived burden. METHOD: a cross-sectional, quantitative study, undertaken in January-April 2010 in Fortaleza, Ceará, Brazil. RESULT: 61 individuals were investigated, monitored by three hospitals' Home Care Program. Data collection was through interviews for identifying life changes, and through the application of three scales for investigating perceived burden, mental state and mental suffering. Respectively these were the Caregiver Burden Scale (CBS, the Mini-Mental State Examination (MMSE and the Self Reported Questionnaire (SRQ. The majority of the carers were female, married, and the children of the stroke patients. The average age was 48.2 years (±12.4. The most-cited life modifications referred to the daily routine, to leisure activities, and to exhaustion or tiredness. Regarding burden, the dimensions of General tension, Isolation and Disappointment stood out. It was ascertained that overload was more severe when the carer presented more symptoms of psychological distress, in the absence of a secondary carer, and when the principal carers reported perceiving changes in their bodies and health. CONCLUSION: an association between burden and the carer's mental state was not observed. Understanding the care, through analysis of the burden and of the knowledge of the biopsychosocial situation will provide support for the nurse's work in reducing the overload for family caregivers.OBJETIVO: analizar el impacto del cuidar para el cuidador familiar de paciente después de accidente vascular cerebral, correlacionando modificaciones de vida y sufrimiento psíquico con la sobrecarga percibida.

    This work describes the current offer for academic and clinical training in medical physics in Argentina; as well as the specific requirements for professional licensing in some specializations, known as individual national license. Reference is made to current local legislation, highlighting the fact that diagnostic radiology does not include the requirement of medical physicist’s compulsory advice. Thus, the labor supply is negligible in this area, to the detriment of the quality of this practice, mainly in terms of radiation protection for patients. Additionally, it is important to highlight the absence of the legal definition of a medical physicist as a health professional in the structure of Health Ministries, which increases disadvantages to those who practice this discipline in public health institutions. Finally, it is noted the absence of doctoral programs in medical physics and its impact on research, development and teaching. (author)

Partiendo de estas bases, se presenta una propuesta de análisis basada en los resultados que la Fiscal Austerity and Urban Innovation (FAUI arrojó para el caso de Argentina. Esta encuesta internacional se orienta principalmente al análisis de estilos de liderazgo en las autoridades municipales a partir de una muestra representativa de intendentes de municipios de 10 mil habitantes o más, un tamaño de municipio mínimo para que exista diversidad y movilización de grupos y asociaciones locales. Para este estudio en particular, orientado al análisis de intereses y actitudes que podrían favorecer o no al desarrollo local, se seleccionaron las variables más relevantes: Alianzas, apoyos recibidos a la candidatura; Interacción con otros actores; Influencia de actores sociales en la definición del gasto; Grado de respuesta a las demandas de diferentes grupos en preferencias de gasto; Prioridades de la gestión; Prioridad en las acciones de gobierno; Preferencia de gasto sobre diferentes áreas de políticas públicas; Ideología y actitudes. En términos generales, los resultados evidencian, por un lado, una tensión entre los nuevos modelos de gestión relacionados con un líder-administrador y los liderazgos más asociados en Argentina a la política tradicional.

    Due to the importance of the winemaking sector in Mendoza, Argentina, the assessment of future scenarios for viticulture is of foremost relevance. In this context, it is important to understand how temperature increase and precipitation changes will impact on grapes, because of changes in grapevine phenology and suitability wine-growing regions must be understood as an indicator of climate change. The general objective is to classify the suitable areas of viticulture in Argentina for the current and future climate using the MM5 regional climate change simulations. The spatial distribution of annual mean temperature, annual rainfall, and some bioclimatic indices has been analyzed for the present (1970-1989) and future (2080-2099) climate under SRES A2 emission scenario. In general, according to projected average growing season temperature and Winkler index classification, the regional model estimates (i) a reduction of cool areas, (ii) a westward and southward displacement of intermediate and warm suitability areas, and (iii) the arise of new suitability regions (hot and very hot areas) over Argentina. In addition, an increase of annual accumulated precipitation is projected over the center-west of Argentina. Similar pattern of change is modeled for growing season, but with lower intensity. Furthermore, the evaluation of projected seasonal precipitation shows a little precipitation increase over Cuyo and center of Argentina in summer and a little precipitation decrease over Cuyo and northern Patagonia in winter. Results show that Argentina has a great potential for expansion into new suitable vineyard areas by the end of twenty-first century, particularly due to projected displacement to higher latitudes for most present suitability winegrowing regions. Even though main conclusions are based on one global-regional model downscaling, this approach provides valuable information for implementing proper and diverse adaptation measures in the Argentinean viticultural

Suele afirmarse que tal situación es la relación directa de los atentados terroristas ocurridos en Buenos Aires en 1992 y 1994 donde las autoridades judiciales argentinas han presentado indicios que relacionarían a funcionarios iraníes. En este trabajo se afirma que aunque tales hechos han tenido influencia las relaciones argentino iraníes constituyen una variable dependiente de los modelos de inserción internacional de Argentina. En tal sentido, la década del gobierno de Carlos Menem (1989-1999 es estudiada como modelo para analizar tales cambios en la política exterior argentina y su impacto en las relaciones argentino-iraníes. Por otra parte, se ha incluido en el análisis el papel de lobbies comunitarios como grupos con incidencia en el proceso de toma de decisiones además de considerar las influencias externas como condicionantes de la política exterior argentina.

    International Nuclear Information System (INIS)

    Full text: The policy established by the National Government of Argentina in August 2006 related to resuming the Nuclear activity in the country, lead the CNEA trough the Exploration of Raw Materials Manager (ERMM) to establish working strategies for the next 10 years. These strategies together with the assignment of an adequate budget will contribute to define new uranium resources, which together with the already known ones, will be used to supply the requirements of Nuclear Power and Research Plants in the future. Thus, the ERMM is applying a policy of human resources hiring new personnel in order to count with the minimum necessary workforce to reach these tasks. In Argentina known U resources are related to sedimentary, igneous and metamorphic environments. Considering the geology of the different regions, Argentina has been divided into 57 units in which the geological, geochemical, mineralogical and structural information is evaluated in order to estimate the uranium geological favorability of each unit. The final pursuit of this regional study is to circumscribe new areas with anomalous uranium contents in which prospection and exploration should be carried out. These studies together with prospection and exploration works are performed in the country by four exploration centers based in Salta (RN), Cordoba (R.Ce), Mendoza (R.Cu) and Trelew (RP). The works planned for each exploration center includes: Regional Noroeste, Mina Franca Deposit: peri-granitic vein- type mineralization: 25% of surface exploration has been performed. Mineralized areas: Istataco and San Buenaventura correspond to an igneous-metamorphic environment, Sierra de Vaqueria to a sedimentary one: Prospection stage. Regional Centro, Mineralized areas: El Gallo: drilling stage and Donato: prospection stage, correspond to an igneous-metamorphic environment with intra and peri-granitic anomalies.

Argentina is one of these countries, with 600 000 people who recognize themselves as indigenous, representing 1.5% of the nation’s entire population. Nevertheless, these populations are still too often marginalized on a regional scale. This is the case for the Mapuche in the Nahuel Huapi National Park, located in the two provinces of Rio Negro and Neuquén. Even though both international and some national texts rehabilitate essential human rights for these populations, local realities are more contrasted due to regional stakeholders’ divergent interests. In the particular context of Argentina, where a large part of the population faces problems gaining access to land, national parks have emerged as a relevant tool for indigenous peoples to recover their ancestral lands, especially thanks to a new process taking place in these territories: co-management.La question des autochtones est devenue, durant les deux dernières décennies, une préoccupation majeure dans différents pays du monde, comme en Argentine où environ 600 000 individus se reconnaissent comme tels, soit 1,5 % de sa population totale. Toutefois, ces populations sont encore trop souvent marginalisées à l’échelle de certaines régions, comme c’est le cas pour les Mapuche du Parc National Nahuel Huapi, situé dans les provinces du Rio Negro et de Neuquén. Si les textes internationaux et parfois nationaux réhabilitent certains droits humains essentiels de ces populations, les réalités locales sont plus contrastées, du fait d’intérêts souvent divergents des acteurs régionaux. Dans le contexte particulier d’une Argentine marquée par des difficultés d’accès à la propriété foncière pour une large part de la population, les parcs nationaux se révèlent être des outils pertinents, pour les populations autochtones, de recouvrement de leurs

    Some reports describe an increased mortality in patients with ankylosing spondylitis (AS) compared to the general population. The aims of this study were to evaluate the cumulative survival in patients with AS and to establish possible factors associated with mortality. In cross-sectional retrospective study, AS patients were included according to 1984 modified NY criteria, in the 2000-2010 period, the prevalence of mortality was determined by review of medical records, telephone contact, family reports, and death certificates, and it was compared with mortality in Argentina's general population. One hundred twenty-seven patients were studied, 96 (75.6 %) were male, median age 49 years (interquartile range (IQR) 34-60) and median disease duration 8 years (IQR 4-17). During the follow-up period, 9 patients died (7.1 %). The median estimated survival from diagnosis of AS was 39 years (IQR 34-50) and median cumulative survival was 76 years (IQR 74-85). Cardiovascular disease was the most frequent cause of death (5/9 patients). Deceased patients had a mean age and a mean AS disease duration significantly higher than living patients (68.1 ± 12.4 years vs 46.4 ± 15.09 years, p = 0.0001 and 33 ± 13.7 years vs 12 ± 10.7 years, p = 0.001, respectively), higher frequency of total surgeries [3/5 (60 %) vs 5/105 (4.76 %), p = 0.002] and cauda equina syndrome [3/6 (50 %) vs 2/116 (1.72 %), p = 0.001], respectively. Frequency of mortality in AS patients was higher than the crude mortality rate of Argentina's general population in the same period, with cardiovascular cause being the most frequent one.

  10. Regulatory aspects of the radioactive waste management in Argentina

    International Nuclear Information System (INIS)

    This paper describes briefly the legislative and regulatory framework in which the radioactive waste management is carried out in Argentina. The activities of the Nuclear Regulatory Authority (NRA) and the applied approaches in relation to inspection of facilities, safety assessments of associated systems and collaboration in the matter with international agencies are also exposed. The 'National Law of the Nuclear Activity' (No. 24804), in force since April 1997, assigns to NRA the following functions: to regulate and to inspect nuclear activities regarding radiological and nuclear safety, physical protection of nuclear materials, in order to verify that such materials are used exclusively with peaceful purposes and also, to advise the National Executive Power in matters of its competence. For the fulfilment of these functions the Law grants to NRA the necessary legal competence to develop, to establish and to apply a regulatory system to all nuclear activities carried out in Argentina. The activity of NRA is carried out in the framework of a regulatory system whose fundamental aspect in the approach adopted to establish the requirements of safety, which is know as 'of performance'. This system has a group of rules known as 'AR Standards' (AR: abbreviation of Regulatory Authority) that, among other requirements, establish that the construction, operation and decommissioning of a nuclear installation can not start without the corresponding construction, operation or decommissioning license. In that sense, besides having the legal competence in the topic, NRA has developed its necessary technical competence to evaluate, with own criteria, all radiological and nuclear safety aspects involved in the grant of licenses and to guarantee an appropriate level of control in the facilities. In relation to the radioactive waste management, NRA has developed some basic criteria. These criteria underline the requirements put to the 'Responsible Entity' that generates or manages

  12. Capturing latecomer advantages in the adoption of biofuels: The case of Argentina

    International Nuclear Information System (INIS)

    Although Argentina came late to the biofuels revolution, a series of measures taken recently at federal and provincial government level have created new opportunities. New federal laws on biofuels promotion have sparked an investment boom. The main activity has been in the biodiesel sector-partly because diesel is the dominant fuel sector in Argentina, and partly because the country had already engineered a soy revolution over the past 15 years, becoming the world's largest exporter of soy oil and soy meal. Biodiesel allows this revolution to be extended-from soy as foodstuff to soy as fuelstock. The biodiesel revolution now underway promises to extend Argentina's latecomer advantages by combining greater scale and lower costs with introduced technical innovations such as genetically modified crops and no-till farming. In this way, Argentina can be seen to be demonstrating the superiority of biofuel production in countries of the South over the conditions obtaining in countries of the North-including superior resources availability, superior energetics and lower costs. Whereas Brazil has demonstrated its superiority in sugarcane-based ethanol, Argentina is about to demonstrate its superiority in soy-based biodiesel

    Although mitochondrial DNA mapping of Varroa destructor revealed the presence of several haplotypes, only two of them (Korean and Japanese haplotypes) were capable to infest Apis mellifera populations. Even though the Korean haplotype is the only one that has been reported in Argentina, these conclusions were based on mites sampled in apiaries from a specific geographical place (Buenos Aires province). To study mites from several sites of Argentina could reveal the presence of the Japanese genotype, especially considering sites near to Brazil, where Japanese haplotype was already detected. The aim of this work was to study the genetic structure of V. destructor populations from apiaries located in various provinces of Argentina, in order to determine the presence of different haplotypes. The study was carried out between January 2006 and December 2009. Phoretic adult Varroa mites were collected from honey bee workers sampled from colonies of A. mellifera located in Entre Ríos, Buenos Aires, Corrientes, Río Negro, Santa Cruz and Neuquén provinces. Twenty female mites from each sampling site were used to carry out the genetic analysis. For DNA extraction a nondestructive method was used. DNA sequences were compared to Korean haplotype (AF106899) and Japanese haplotype (AF106897). All DNA sequences obtained from mite populations sampled in Argentina, share 98% of similitude with Korean Haplotype (AF106899). Taking into account these results, we are able to conclude that Korean haplotype is cosmopolite in Argentina.

Un 17% de los casos fueron menores de 15 años, lo que indica una activa transmisión de la infección, que se diagnostica generalmente ya con enfermedad avanzada, por la historia de foco, la reacción tuberculínica positiva, y los signos y síntomas clínico- radiológicos. El aporte de la bacteriología al diagnóstico es escaso, empleándose en 0-4 años el aspirado o lavado gástrico. Para el cultivo se usan los medios sólidos a base de huevo o, en laboratorios de referencia, los de detección temprana. Las pruebas de amplificación de ácidos nucleicos están disponibles en algunos laboratorios, pero sin un sistema de garantía de calidad; sus resultados deben considerarse sólo dentro del contexto clínico. El fortalecimiento de la red de laboratorios de cultivo facilitará el diagnóstico de certeza de la TBC infantil, la confiabilidad de la notificación, y el conocimiento de la resistencia bacteriana. Para revertir la actual situación epidemiológica es necesario incrementar la investigación de los niños contactos de casos bacilíferos, seguida de quimioprofilaxis o tratamiento según corresponda. La meningitis TBC en menores de 5 años tuvo una disminución significativamente mayor que la de la TBC en adultos, en los últimos 20 años en Argentina.

    Full Text Available In this contribution, we describe latest Cretaceous aquatic plant communities from the La Colonia Formation, Patagonia, Argentina, based on their taxonomic components and paleoecological attributes. The La Colonia Formation is a geological unit deposited during a Maastrichtian-Danian transgressive episode of the South Atlantic Ocean. This event resulted in the deposition of a series of fine-grained sediments associated with lagoon systems occurring along irregular coastal plains in northern Patagonia. These deposits preserved a diverse biota, including aquatic and terrestrial plants and animals. The aquatic macrophytes can be broadly divided into two groups: free-floating and rooted, the latter with emergent or floating leaves. Free-floating macrophytes include ferns in Salviniaceae (Azolla and Paleoazolla and a monocot (Araceae. Floating microphytes include green algae (Botryoccocus, Pediastrum and Zygnemataceae. Among the rooted components, marsileaceous water ferns (including Regnellidium and an extinct form and the eudicot angiosperm Nelumbo (Nelumbonaceae are the dominant groups. Terrestrial plants occurring in the vegetation surrounding the lagoons include monocots (palms and Typhaceae, ferns with affinities to Dicksoniaceae, conifers, and dicots. A reconstruction of the aquatic plant paleocommuniy is provided based on the distribution of the fossils along a freshwater horizon within the La Colonia Formation.

    The Alumbrera copper-gold mine located in the Province of Catamarca, northwest region of Argentina, commenced operation in October, 1997. Mine development included a 316 km long, 175 mm diameter slurry pipeline that conveys copper concentrate to a dewatering facility near the city of Tucuman, Province of Tucuman. It became apparent during the first few years of operation that, given the many potential risks of pipeline exposure associated with stream crossings, Minera Alumbrera would have to undertake an aggressive, formal program of risk management of crossings and risk mitigation. In this paper, the experience associated with two crossings is addressed: Rio Villavil; and, Rio Gastona. The original pipeline route through the 10 km length of pipeline connecting Pump Station (PS) 2 to PS 3 was directed along the bottom of the Rio Villavil valley, with most of it located within the flood way of the stream. The exposure of the pipeline at some locations and high risk of further pipeline exposures led to initiation of risk mitigation planning. Remediation work was completed by 2008. Rio Gastona, during the summer of 2001, experienced rapid shifting of the left bank at the crossing resulting in an undermined and unsupported length of pipeline. The subsequent risk mitigation method adopted in 2001 involved the planning and construction of groyne fields along both banks. (author)

    During the period 1994-95, solar photovoltaic systems were installed at a number of schools in Neuquen Province, Argentina, by the Provincial electric utility, Ente Provincial de Energia del Neuquen. This was undertaken with funds provided by the Inter-American Development Bank. In all, there are 12 schools that have had photovoltaic generating systems installed. These generating systems are designed to provide electricity for the basic needs at the schools: primarily for lighting, and to operate small electrical appliances such as communication radios, televisions, VCR`s, AM/FM and short-wave radios. They do not provide enough energy to operate large consumption appliances such as washing machines, microwaves, refrigerators, power tools, etc. The program of provision of PV systems was supplemented with training on simple systems for cooking food or drying fruit, etc. These techniques are primarily intended for demonstration at the schools thus serving an educational role with the hope that they will be transmitted in time to the families of the students where the need is manifested the most.

  9. Notes on the present situation of Anastrepha fraterculus in Argentina

    International Nuclear Information System (INIS)

    Behavioural and karyotypical results from Anastrepha fraterculus samples received in our laboratory during the period 92-94 are discussed. The work represents the partial situation of this pest in Argentina. Data from guava fruits indicate 1) that the oviposition behaviour does not agree with the autocontrol mechanism via ODP previously described, 2) that a selection mechanism associated to fruit size and quality exists, allowing the female to choose the oviposition site, 3) if different varieties of fruits are available, then the fly shows preference for one of them. The oviposition behaviour in samples of peaches is different from that observed on guava samples and agrees with the ODP mechanism. In some localities, A. fraterculus and C. capitata share the same substrate or fruit (same unit). Samples from commercial oranges do not show evidence of Anastrepha attack. A more frequent karyotype fArg 1 (wild type karyotype) as well as high karyotypic variation, mainly measured through the polymorphism of sexual chromosomes, are present within different geographic populations sharing the same host species. To date, we do not have enough information to associate a particular behaviour to a karyotype. The chromosomal analysis is merely descriptive. (author)

  10. Leishmaniasis and Climate Change—Case Study: Argentina

    Full Text Available Vector-borne diseases closely associated with the environment, such as leishmaniases, have been a usual argument about the deleterious impact of climate change on public health. From the biological point of view interaction of different variables has different and even conflicting effects on the survival of vectors and the probability transmission of pathogens. The results on ecoepidemiology of leishmaniasis in Argentina related to climate variables at different scales of space and time are presented. These studies showed that the changes in transmission due to change or increase in frequency and intensity of climatic instability were expressed through changes in the probability of vector-human reservoir effective contacts. These changes of contact in turn are modulated by both direct effects on the biology and ecology of the organisms involved, as by perceptions and changes in the behavior of the human communities at risk. Therefore, from the perspective of public health and state policy, and taking into account the current nonlinear increased velocity of climate change, we concluded that discussing the uncertainties of large-scale models will have lower impact than to develop-validate mitigation strategies to be operative at local level, and compatibles with sustainable development, conservation biodiversity, and respect for cultural diversity.

    The Cherenkov Telescope Array (CTA) Project will consist of two arrays of atmospheric Cherenkov telescopes to study high-energy gamma radiation in the range of a few tens of GeV to beyond 100 TeV. To achieve full-sky coverage, the construction of one array in each terrestrial hemisphere is considered. Suitable candidate sites are being explored and characterized. The candidate sites in the Southern Hemisphere include two locations in Argentina, one in San Antonio de los Cobres (Salta Province, Lat. 24:02:42 S, Long. 66:14:06 W, at 3600 m.a.s.l) and another one in El Leoncito (San Juan Province, Lat. 31:41:49 S, Long. 69:16:21 W, at 2600 m.a.s.l). Here we describe the two sites and the instrumentation that has been deployed to characterize them. We summarize the geographic, atmospheric and climatic data that have been collected for both of them.

    Full Text Available Este proyecto busca aplicar la técnica estadística de análisis de datos composicionales al estudio de las tasas de inactividad en la económica República Argentina. Se intenta validar la hipótesis de la existencia de efectos alométricos entre los niveles de inactividad económica por gran aglomerado urbano y la composición de los mismos según los distintos causales de inactividad. Es decir, si la proporción de inactivos por las distintas razones de inactividad está correlacionada con la tasa de inactividad por gran aglomerado urbano. Se han encontrado efectos alométricos en estudios regionales de inactividad en el Reino Unido, según los cuales algunas causas de inactividad, como incapacidad, estarían fuertemente correlacionadas con los niveles totales de inactividad por región. Sin embargo, los resultados para la onda de Mayo 2003 permiten en general rechazar la hipótesis de que la composición de la inactividad por aglomerado urbano esté asociada con las tasas de inactividad.

    The health care services managed by trade unions and known as "Obras Sociales" form the groundwork for Argentina's Social Security and Health system. However, far from taking an equitable approach, these institutions highlight the country's prevailing income disparities, which in turn lead to major differences in access to care. The main focus of this study was the reformulation of social security health policies within the framework of deregulation from 1998 to 2000, analyzing the effects on availability of health care services from an equity perspective. The methodology used two related analytical levels: (1) a macro level viewing the process from the various players' strategies and (2) a micro level featuring the changes within a well-known trade union social security organization during its reconversion process, emphasizing its institutional scope and the opinions of its membership. The results thus pointed to the slow implementation of reforms initiated by the public sector, hindered by constant negotiations among the main corporate actors seeking to serve their particular interests, along with increased inequity and fragmentation due to the limited opening of free choice by members.

    Genital infection with human papillomavirus (HPV) is decisive in the causation of cervical cancer. In order to evaluate the epidemiology of HPV infection in Ushuaia, Province of Tierra del Fuego, Argentina, 132 endocervical cytobrushes from preneoplastic and neoplastic cases and controls were studied. Detection and typing of the viral genome was performed by polymerase chain reaction, combined with a restriction fragment length polymorphism assay or hybridization. The overall prevalence of HPV infection was 41% in the population examined, with a frequency of 26% in the controls and 71% in the cases under study. The 14-24 age group showed the highest HPV prevalence. The most common viral types in the infected population were HPV 16 (23%), HPV 18 (11%), HPV 33 (8%) and HPV 35 (8%), while high risk viral types were detected in 30% of the samples, 16% of the controls and 60% of the cases. This study provides the first data on the predominant viral types in Ushuaia. Our results show lower levels of infection than in regions with a high incidence of cervical cancer, HPV 16 being the most prevalent viral type. This research may be useful for selecting a specific vaccine targeting the population examined. PMID:16784128

    The expedition in November-December 2005 to Isla de los Estados (Staten Island) off the southeastern tip of South America was a cooperative venture between Lund University (LU) and Stockholm University (SU) in Sweden and the CADIC-CONICET Institute in Ushuaia, Argentina. The aim of the expedition was threefold: (1) to extend the Swedish paleoclimatic "ATLANTIS"-project (Greenland, Iceland, Faroe Islands, Azores, Grenada, Tristan da Cunha; PI S Björck) to the southern part of the South American continent, (2) to connect earlier glacial and climate history reconstructions from the Antarctic Peninsula to equivalents north of the Drake Passage in southernmost South America, and (3) to complement paleo-information available from the Tierra del Fuego mainland with information from Isla de los Estados. Focus was on two areas in the northern and north-western part of the island, Bahía Colnett and Bahia Crossley. Detailed geomorphologic and stratigraphic mapping of glacial deposits were combined with sampling sediments for OSL dating. To reconstruct the paleoclimatic development of Isla de los Estados since the last ice retreat, four main peat bog/lake sites were cored and sampled. In addition, living trees of Nothofagus and old logs preserved in the peat were sampled for dendrochronological and dendroclimatological studies. Preliminary results show that the deglaciation of the study area occurred before 16500 cal yr BP. Detailed multi- proxy analyses of the four sequences are under way and first results will be presented.

El análisis espacial, en este trabajo, es el contexto y el pretexto de una interpretación geográfica de las peregrinaciones en Argentina. Religión, espacio y cultura, nos permiten comprender las significaciones compartidas y producidas por la comunidad católica, yendo más allá, de definiciones impuestas o con sentido mezquino. En este punto interceden marcos interpretativos e ideas tendientes a “descubrir” verdades incompletas que subrayan la mutua exclusión entre modernidad y religión, marcos que no pueden dar respuesta a la complejidad de nuestra sociedad contemporánea. De allí que el territorio no es un simple escenario de las prácticas sino una expresión de esta complejidad social y religiosa.

  17. Elemental characterization of air particulate matter in Buenos Aires, Argentina

    International Nuclear Information System (INIS)

    Buenos Aires, the capital city of Argentina, is surrounded by 24 neighboring districts forming the so-called Buenos Aires metropolitan area (AMBA) that holds a population of 14 million people. In this work, the atmospheric aerosol of this metropolitan area was characterized through the determination of mass concentration, black carbon and elemental concentrations, on PM10 and PM2.5 samples taken using a 'Gent' sampler. The sampling site was located at an urban area characterized by fast and heavy traffic and samples were collected each third day, along 24 hours, between October 2005 and February 2006. A number of elements (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Na, Rb, Sb, Sc, Se, Sm, Th, Yb and Zn) were determined by Neutron Activation Analysis and their results, as well as those of gravimetric mass concentrations, were compared with historical data. Enrichment factors were calculated for both fractions, using Sc as reference element and Mason's crustal concentration values, showing enrichment for As, Br, Sb, Se and Zn. Although the number of analyzed filters is still small, a preliminary factor analysis was run on both fraction results and different source profiles were found. The attribution of the sources to soil, high temperature processes including refuse incineration, fuel combustion and others, metal processes, traffic and other anthropogenic ones is discussed.

    A stochastic simulation model was developed to carry out the first quantitative risk exposure assessment of the mycotoxin level in cow's milk produced in Argentina. The prevalence and concentration of aflatoxin M1 (AFM1), deoxynivalenol (DON) and zearalenone (ZEA) were modeled at various stages through milk processes complying with Argentinean practices. Concentration of AFM1 (0.059ppb), DON (0.338ppb) and ZEA (0.125ppb) in dairy milk were estimated. The proportion of feed samples that exceeded the maximum level accepted by European regulations for AFB1, DON and ZEA were estimated at 25.07%, 0.0% and 8.9%, respectively. The percentage of milk samples that exceeded the maximum level accepted for AFB1 by the MERCOSUR (0.5ppb) and the European Union regulations (0.05ppb) were 0.81 and 32.65, respectively. The probability distribution of AFM1 concentration in milk was affected by the carry-over rate equations applied in the model. Mycotoxin levels in corn silage and concentrated feeds were the factors most correlated with mycotoxin concentrations in milk. Therefore, agricultural practices, crop management and feed production require prompt attention regarding mycotoxin issues.

  19. Oil and democracy in Argentina, 1916-1930

    International Nuclear Information System (INIS)

    Argentine society in the 1920s experience strong political, cultural, and economic divisions between the littoral regional surrounding Buenos Aires and the interior provinces to the west and north. Economic recession through World War 1 sparked efforts to wean the economy from total dependence upon agricultural production and export, and petroleum deposits in the south and northwest corners of Argentina offered a wider economic base. Regional conflict quickly arose concerning oil production and control over oil revenues. By mounting a popular anti-imperialist campaign against Standard Oil of New Jersey, the primary interior oil producer, dominant political forces in Buenos Aires worked to nationalize all oil deposits to the detriment of interior provincial interests. To maintain the kinds of political control necessary to fend off this threat, interior conservatives reverted to electoral fraud and violence, especially in the major oil-producing province of Salta. This thesis reconstructs and analyzes the process by which political division on the oil issue hardened and gave way to a conservative reaction leading to an authoritarian regime

    This paper was prepared based on the optimization of the performance and wear pattern of Polycrystalline Diamond Cutter (PDC) bits used in 25 de Mayo S.E. El Medanito Field, Neuquen/Argentina out of a joint effort done by the operator and the service company. The main objective was to reach the casing point in a single bit run at a reasonable penetration rate of the 8 1/2'' section (Choiyoi Formation - Igneous Rock), in order to avoid the use of an extra tungsten carbide insert roller cone bit to reach (4400 ft) which increases the drilling costs as well as allows to a higher exposure to accidents during trips in and out of the hole. A methodology was introduced to the field operations enabling a close follow-up to optimize the drill bit cutting structures, operating conditions, as well as the incorporation of state-of-the-art technology regarding cutters and its geometry. This proved less wear on cutting structures of PDC bits, leading to the achievement of the established casing set depth with reduction of drilling hours and being cost effective to the Operator.

    OBJECTIVE Identify spatial distribution patterns of the proportion of nonadherence to tuberculosis treatment and its associated factors. METHODS We conducted an ecological study based on secondary and primary data from municipalities of the metropolitan area of Buenos Aires, Argentina. An exploratory analysis of the characteristics of the area and the distributions of the cases included in the sample (proportion of nonadherence) was also carried out along with a multifactor analysis by linear regression. The variables related to the characteristics of the population, residences and families were analyzed. RESULTS Areas with higher proportion of the population without social security benefits (p = 0.007) and of households with unsatisfied basic needs had a higher risk of nonadherence (p = 0.032). In addition, the proportion of nonadherence was higher in areas with the highest proportion of households with no public transportation within 300 meters (p = 0.070). CONCLUSIONS We found a risk area for the nonadherence to treatment characterized by a population living in poverty, with precarious jobs and difficult access to public transportation. PMID:26270011

    2009-12-01

    Groundwater in the central part of Argentina contains arsenic concentrations that, in most cases, exceed the value suggested by international regulations. In this region, Quaternary loessical sediments with a very high volcanic glass fraction lixiviate arsenic and fluoride after weathering. The objectives of this study are to analyze the spatial distribution of arsenic in different hydrogeological regions, to define the naturally expected concentration in an aquifer by means of hydrogeochemistry studies, and to identify emergent health evidences related to cancer mortality in the study area. The correlation between arsenic and fluoride concentrations in groundwater is analyzed at each county in the Cordoba Province. Two dimensionless geoindicators are proposed to identify risk zones and to rapidly visualize the groundwater quality related to the presence of arsenic and fluoride. A surface-mapping system is used to identify the spatial variability of concentrations and for suggesting geoindicators. The results show that the Chaco-Pampean plain hydrogeologic region is the most affected area, with arsenic and fluoride concentrations in groundwater being generally higher than the values suggested by the World Health Organization (WHO) for drinking water. Mortality related to kidney, lung, liver, and skin cancer in this area could be associated to the ingestion of arsenic-contaminated water. Generated maps provide a base for the assessment of the risk associated to the natural occurrence of arsenic and fluoride in the region. PMID:19165608

    Full Text Available OBJECTIVE: This study estimates the costs of maternal health services in Rosario, Argentina. MATERIAL AND METHODS: The provider costs (US$ 1999 of antenatal care, a normal vaginal delivery and a caesarean section, were evaluated retrospectively in two municipal hospitals. The cost of an antenatal visit was evaluated in two health centres and the patient costs associated with the visit were evaluated in a hospital and a health centre. RESULTS: The average cost per hospital day is $114.62. The average cost of a caesarean section ($525.57 is five times greater than that of a normal vaginal delivery ($105.61. A normal delivery costs less at the general hospital and a c-section less at the maternity hospital. The average cost of an antenatal visit is $31.10. The provider cost is lower at the health centre than at the hospital. Personnel accounted for 72-94% of the total cost and drugs and medical supplies between 4-26%. On average, an antenatal visit costs women $4.70. Direct costs are minimal compared to indirect costs of travel and waiting time. CONCLUSIONS: These results suggest the potential for increasing the efficiency of resource use by promoting antenatal care visits at the primary level. Women could also benefit from reduced travel and waiting time. Similar benefits could accrue to the provider by encouraging normal delivery at general hospitals, and complicated deliveries at specialised maternity hospitals.

    In January 2009 during an oil well logging task in Rincon de los Sauces, Province of Neuquen, Argentina, and, as a result of the temporary loss of control of a 137Cs sealed source of 92,5 GBq (2,5 Ci), two workers were allegedly exposed to ionizing radiation. The Health Emergency Coordination System in Neuquen activated the Radiological Emergency Intervention System of the Nuclear Regulatory Authority (NRA). An initial assessment of the accident scenario and the involved persons was performed. Two workers were were transfer to Buenos Aires for a biodosimetry evaluation. In Buenos Aires, the Burn Hospital performed the first diagnostic and therapeutic approach of the radioinduced skin injuries. The NRA estimated the biological absorbed doses and the studies of telethermography. The Italian Hospital was in charge of the studies using ultrasonography and Eco- Doppler. As a result of the multidisciplinary evaluation performed, one of the workers was diagnosed with superficial radioinduced dermatitis. The mentioned intervention highlighted the importance of multidisciplinary and multiparametric work for the evaluation of a radiological accident, as well as for the diagnosis and early treatment of the exposed persons.

    This article describes the first fossils recorded in the Hernandarias Formation (Pleistocene) in Entre Ríos province (eastern Argentina). They are represented by three teeth assigned to the caviomorph rodents (Rodentia, Mammalia) Aenigmys diamantensis gen. et sp. nov. and Eumysops. To establish the phylogenetic affinities of the two most enigmatic teeth, their enamel microstructure was studied. Aenigmys diamantensis is considered the most primitive taxon of a clade formed by Dinomyidae-Neoepiblemidae-Heptaxodontidae. Evidence of the close relationships among these families also is presented herein. The new fossils reinforce previous hypotheses about the survival of primitive Brazilian taxa after their extinction in the Pampas and Patagonia of southern South America. They also show that the diversity of caviomorph rodents during the Quaternary was greater than supposed and that an important Quaternary extinction, not previously detected, affected several lineages. With the available evidence, it is not possible to determine if these rodents indicate a warm pulse or a particular biogeographic situation in Entre Ríos.

    A survey over two mountain slopes (Glaciar Martial and Cerro Guanaco) in the vicinity of Ushuaia (Tierra del Fuego, Argentina) showed normal results for the region in terms of chlorophyll concentration in the leaves of the dominant tree species Nothofagus antarctica, N. pumilio and N. betuloides, and soil variables such as temperature, moisture, pH, and concentration of nitrogen, sodium and potassium. Solar radiation, on the other hand, showed high values of ultraviolet over the 200-400 nm range, suggesting that the environment is extreme in terms of incoming solar radiation. The forest canopy absorbs and/or reflects a significant amount of that radiation. In separate analyses we showed that these tree species contain UV-absorbing pigments (cyanidin, delphidin, and flavonol glycosides). We submit that the rippled and glossy surface of leaves serves as a reflection/backscattering mechanism that protects their inner structure and function. The presence of krummholz (= twisted, dwarf trees) in the upper end of the forest shows the effects of an extreme environment.

Hungarianémigré organizations formed a "Comité de Ayuda pro Hungría Libre" (Aid Committee for a FreeHungary, coordinating the strategies and actions aimed at providing moral and material supportfor the revolution. Supplementing and aiding these actions were those of the Argentinegovernment and population at large. The government named a special commission for refugees;and there was a tremendous outpour of sympathy and material support for Hungarians amongArgentines, with major press coverage for months to come. Of special importance is the literaryand press output following the revolution. These actions provoked fear and rejection from theEmbassy of the People's Republic of Hungary, and it accused the Argentine government of openlysiding with the émigrés. Upon the Hungarian Foreign Ministry's instructions, the Embassystrongly intensified the espionage on the émigré institutions and its prominent members for years.Relations between émigré organizations and the Hungarian Government remained nonexistent orstrained until the lifting of the Iron Curtain in 1990.

    In Argentina the Yungas forests are among the ecosystems most affected by human activity, with loss of biodiversity. To assess the arbuscular mycorrhizal (AM) colonization and the arbuscular mycorrhizal fungi (AMF) spore numbers in these ecosystems, the roots of the most dominant native plants (one tree, Alnus acuminata; three herbaceous, Duchesnea indica, Oxalis conorrhiza, Trifolium aff. repens; and one shrub, Sambucus peruviana) were studied throughout the year from two sites of Yungas forests. Assessments of mycorrhizal colonization (percent root length, intraradical structures) were made by washing and staining the roots. Soil samples of each plant species were pooled and subsamples were obtained to determine AM spore numbers. The herbaceous species formed both Arum- and Paris-type morphologies, whereas the tree and the shrub species formed respectively single structural types of Arum- and Paris-type. AM colonization, intraradical fungi structures and AMF spore numbers displayed variation in species, seasons and sites. D. indica showed the highest AM colonization, whereas the highest spore numbers was observed in the rhizosphere of A. acuminata. No correlation was observed between spore numbers and root length percentage colonized by AM fungi. Results of this study showed that Alnus acuminata is facultatively AM. The AM colonization, intraradical fungi structures and AMF spore numbers varied in species depending on phenological, climatic and edaphic conditions. PMID:19750940

    In the area of the Copahue Geothermal Field, there are five active geothermal manifestations, which mainly consist of fumaroles, hot springs and mud pots. Four of these manifestations are located in Argentina: Las Máquinas, Termas de Copahue, Las Maquinitas and El Anfiteatro, and the fifth on the Chilean side: Chancho Co. All of them present a strong acid sulfate country rock alteration, characterized by the assemblage alunite + kaolinite + quartz + cristobalite + pyrite + sulfur + jarosite, as the result of the base leaching by fluids concentrated in H2SO4 by atmospheric oxidation at the water table in a steam heated environment of H2S released by deeper boiling fluids. Another alteration zone in this area, called COP-2, is a fossil geothermal manifestation which shows characteristics of neutral to alkaline alteration represented mainly by the siliceous sinter superimposed over the acid alteration. The mineralogy and zoning of these alteration zones, and their relation with the hidrothermal solutions and the major structures of the area are analized.

  17. Assessment of Market Efficiency in Argentina, Brazil and Chile: an Event Study of Mergers and Acquisitions

    2012-04-01

    Full Text Available This paper presents an investigation into the relationship between the announcement of mergers and acquisitions, the existence of positive abnormal returns for shares of these firms, and market efficiency in Argentina, Brazil and Chile. Statistically significant Standardized Abnormal Returns were present in the event announcement and the following days in Argentina and Chile and on the event day in Brazil, confirming value creation signaling. Furthermore, the significance of abnormal returns in the event window, namely in the 5 days following the event in Argentina and Chile and the absence of such in Brazil suggests a more efficient market exists in Brazil, in keeping with the semi-strong market efficiency hypothesis. The absence of semi-strong efficient market behavior could prove valuable to investors who could use a window of a few days after the event announcement to accumulate abnormal returns, provided the appropriate research into news of possible mergers or acquisitions has been made.

    Parasites display considerable phenotypic plasticity in life-history traits such as, body size. Varroa destructor is an ectoparasitic mite of the western honey bee Apis mellifera. Several studies have reported that in V. destructor, there is a wide phenotypic plasticity within a population of mites. However, it is unknown if there are morphologic variations in V. destructor populations affecting different A. mellifera populations. A morphometric study of V. destructor populations was conducted to provide information concerned to the relationships among parasite populations found in different geographic locations from A. mellifera colonies of Argentina. The hypothesis tested was different morphotypes of V. destructor populations parasitizing different A. mellifera populations from Argentina exist. A discriminant analysis employing eight morphologic variables revealed that it is possible to differentiate morphotypes of mites in Argentina. However, the level of discrimination detected among mites population varied according to the grouping of mite's population. Possible causes explaining the morphometric variability in the V. destructor populations were discussed.

    Full Text Available At the time of our investigation, the CU was not a widespread concept in Argentina, being viewed as a “foreign - far long project” (coming from developed countries and standing for the long term. It is suggested that the rate of CU evolution, in emerging countries like Argentina, is more related to mentality issues than to CU strategic or operative limitations. Although the executives who replied to a survey were not the only power factor in their organization, their comments allow us to think that, in those countries, the CU may have a better future perspective. The research used a quali-quantitative methodology, which was based on a survey to top executives of different kinds of companies located in Argentina. The research design was not experimental and transversal, as it was limited to a specific moment in time.

    Full Text Available Entre 1905 y 1910 Chile y Argentina negociaron la firma de un Tratado de Comercio con vistas a suprimir los aranceles aduaneros y consagrar el principio de "Cordillera Libre". El centro de atracción eran las exportaciones de ganado argentino a Chile y de vino chileno a Argentina. Pero en ambos países se produjo una fuerte reacción de los intereses creados con vistas a frustrar las tratativas diplomáticas. Tanto la Sociedad Nacional de Agricultura (Chile como el Centro Vitivinícola Nacional (Argentina realizaron intensas gestiones para alcanzar sus objetivos; esta última corporación llegó a movilizar miles de personas para oponerse al tratado; y hasta solicitó ayuda a los ferrocarriles británicos para que obstaculizaran el ingreso de los vinos chilenos al mercado argentino. La intensa resistencia de estas corporaciones terminaron por frustrar el proyecto, el cual fue definitivamente archivado en 1911.Between 1905 and 1910, Chile and Argentina negotiated the signature of a Trade Agreement in order to abolish the customs duties and consecrate the principle of "Free Mountain Range". The centre of attraction was the exports of Argentinean cattle to Chile and of Chilean wine to Argentina. But in both countries there aroused a strong reaction of the vested interests, purposely to thwart the diplomatic negotiations. Both, the Sociedad Nacional de Agricultura (Chile as well as the Centro Vitivinícola Nacional (Argentina carried out intense negotiations to reach their objectives; the latter even movilized thousands of people to oppose the treaty and went as far as requesting the help of the British railroads to block the entrance of Chilean wines to the Argentinean market. The stiff opposition of these corporations finally frustrated the project, which was definitively filed away in 1911.

    129I/127I ratios and iodine concentrations in bovine thyroids stemming from Argentina were determined by accelerator mass spectrometry (AMS) and gas chromatography (GC), respectively. From these measurements, a relationship of the 129I/127I ratio with iodine content in the gland was obtained. A weak correlation between the two isotopes was found, suggesting that 129I re-emission from the ocean is not the only process for the 129I deposition in Argentina. Moreover, contributions to the total 129I inventory in the Southern hemisphere from both natural and anthropogenic sources were theoretically studied. Surface compartments present similar contribution from natural sources and nuclear explosions fallout.
