    Full Text Available Asumiendo como contexto el avance de los procesos de globalización, reestructuración económica y reforma del Estado, el presente artículo desarrolla una breve caracterización y análisis de las principales transformaciones socio-territoriales del Área Metropolitana de Montevideo. Éstas se relacionan con el comportamiento de la población; los cambios en la estructura y morfología del territorio; las modificaciones en la base económica; el avance en los procesos de segregación social; y las modalidades de gestión institucional. A su vez, se generan algunas reflexiones en torno a estas variables relevantes que permiten identificar ciertas singularidades del proceso metropolitano de MontevideoIn the context of globalization processes, economic restructuring and state reform, the article describes and analyses the main social and territorial transformations that have been taking place in Montevideo Metropolitan Area. This transformations mainly refer to population dynamics, changes in the structure and morphology of the territory and changes in the economic base, as well as the advance in social segregation processes and new arrangements for institutional management. Finally, some reflections around these issues are proposed, leading to the identification of singularities in the Montevideo metropolitan process

    Full Text Available El crecimiento de las ciudades genera modificaciones en la atmósfera local que pueden afectar la confortabilidad y calidad de vida de la población. El objetivo del presente trabajo fue comparar la evolución de la isla de calor de verano e invierno entre los años 1985 y 2014 en Bahía Blanca (Argentina. Esta ciudad ha sufrido un importante aumento de la población y de las actividades industriales en los últimos años. Se estudió el aumento de la zona urbana construida, las variaciones espaciales de temperatura y humedad relativa y el crecimiento de la población. Se calcularon índices de confort climático (Humidex, Termohigrométrico y Temperatura Equivalente. La zona urbana construida se extendió más de 110 km² y el incremento de la población fue de 22,4 %. Las modificaciones en el espacio urbano, junto con una mayor densidad de edificios, generaron cambios en las temperaturas de verano de 1985 y 2014. En la primera el centro de la ciudad fue más cálido que las zonas periféricas. La zona más confortable fue la costera. En 2014, en el centro de la ciudad se presentaron las temperaturas más altas y las zonas más confortables fueron las periféricas y los parques. Las mediciones de invierno no registraron diferencias considerables entre sí en las mediciones nocturnas. Los resultados demostraron que el crecimiento de las edificaciones y el incremento de la población de Bahía Blanca modificaron la distribución espacial de la temperatura y la humedad relativa y generaron situaciones de desconfort. Estos resultados generaron información necesaria para futuros planes de desarrollo urbano.

    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.

    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 El presente trabajo tiene como objetivo realizar un diagnóstico ambiental de un sector de la ciudad de Bahía Blanca, Argentina basado en el arbolado urbano de alineación. El arbolado constituye un componente fundamental de los paisajes artifi ciales ya que contribuye al aumento del confort y al mejoramiento de la calidad del medio. En este sentido, actúa como un factor moderador de las condiciones climáticas, la contaminación y la salud de la población. El municipio de la ciudad de Bahía Blanca tiene como proyecto la realización de inventarios del arbolado en los distintos barrios, para lograr optimizar la relación entre la cantidad de ejemplares arbóreos y la densidad poblacional. Es importante considerar la variedad de ejemplares en función del uso del suelo y de las características ambientales de cada sector. Por lo tanto, este trabajo presenta un diseño metodológico para la elaboración del plano verde de la ciudad.

    In 1987 Argentina had a population of 31.5 million, with an annual rate of increase of 1.6%. The total fertility rate was 3.3, and the birth rate was 24/1000 population. Mortality stood at 8/1000 population, and the infant mortality rate was 35.3/1000 live births. Life expectancy at birth is 70 years. 84% of the population lives in Argentina's urban areas. Current government policies call for regional development to maintain and increase population in rural areas and control growth in urban centers. 90% of the population is of European descent, largely as a result of high rates of immigration during the 1880s-1930s from countries such as Spain and Italy. In 1985 the gross national product per capita was US$2130. Argentina is rich in resources and almost self-sufficient in terms of basic foodstuffs, power supply, and advanced communication networks. On the other hand, political conflicts and economic crises have hindered the realization of both human and natural resource potential. 80% of the value of export products is the amount due in interest on foreign debts.

    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.

Para este fin, se ha realizado un análisis comparativo de todas las sentencias de este tipo de procedimientos de un Juzgado de Familia entre los años 2011 y 2012 (N = 261. En concreto, se han comparado las sentencias correspondientes al año 2011 (N = 134, año anterior a la entrada en vigor de la ley, y las del año 2012 (N = 127. De entrada, este descenso per se, ya contradice la idea de efecto de demandas masivas que se pudo presuponer a priori del cambio de ley. Además, en las motivaciones de las modificaciones demandadas de manera contenciosa del año 2012, está más presente la voluntad de modificar los gastos para con los hijos/as menores, que una coparentalidad equitativa en tiempos y recursos similares.

    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

The success of insecticide spraying campaigns, even with simultaneous amelioration of housing, are enhanced by tne modification of the biotopes. A pilot field experience is presented; a 2 year active campaign in a suburban area of Villa Carlos Paz, province Cordoba, Argentina, confirming the methods to eliminate reinfestation of houses from peridomestic sites, in an area of low vector density.

    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.

    Full Text Available Este artículo trata sobre un período de la historia argentina en el cual la "mirada médica", a través de un grupo de prestigiosos intelectuales, se convirtió en una clave de interpretación de la sociedad argentina. El análisis gira en torno a la obra de uno de los médicos higienistas más influyentes, José María Ramos Mejía, deteniéndose especialmente en su libro más famoso: Las multitudes argentinas (1899. La hipótesis principal que recorre el texto es la siguiente: la medicalización de la sociedad, acentuada luego de las epidemias de cólera y fiebre amarilla de mediados del siglo XIX, ofreció a las elites públicas la posibilidad de construir dominios legítimos de intervención estatal. Intromisiones del Estado en la vida privada que, además de ser algo resistidas por la población, entraban en tensión con los principios teóricos del liberalismo que los propios miembros de la elite defendían.

  18. Soft rocks in Argentina

    Institute of Scientific and Technical Information of China (English)

    Giambastiani; Mauricio

    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.

    Full Text Available Tick paralysis (TP occurs worldwide and is caused by a neurotoxin secreted by engorged female ticks that affects the peripheral and central nervous system. The clinical manifestations range from mild or nonspecific symptoms to manifestations similar to Guillain-Barré syndrome, bulbar involvement, and death in 10% of the patients. The diagnosis of TP is clinical. To our knowledge, there are no formal reports of TP in humans in South America, although clusters of TP among hunting dogs in Argentina have been identified recently. In this paper, clinical features of two cases of TP occurring during 1994 in Jujuy Province, Argentina, are described.

    Although they have been equitable compared, the energy policies taken by Brazil and Argentina as a solution to the energy crisis lived by each one of these countries in years 2001 and 2002, they have enormous differences in terms of the real problem and nature of the established measures. Firstly the central aspects of the demand rationing mechanism adopted by Brazil for the electrical crisis of 2001 are presented. Afterwards the measures adopted in Argentina during the 2004 crisis in the electricity and natural gas rationing are discussed. From this exhibition of facts, comparisons are made and conclusions extracted looking forward to clarify the important differences separating both cases, differences that as the study reveals meant for the Argentine scheme the breach of the expected objectives. In the last section the changes implemented in the Argentine scheme are reflected during year 2005 to counteract the bad results obtained, nevertheless this modifications attacked only in a partial way the original program weaknesses.

  13. Anaglyph: Patagonia, Argentina

    2000-01-01

    This view of northern Patagonia, near El Cain, Argentina shows complexly eroded volcanic terrain, with basalt mesas, sinkholes, landslide debris, playas, and relatively few integrated drainage channels. Surrounding this site (but also extending far to the east) is a broad plateau capped by basalt, the Meseta de Somuncura. Here, near the western edge of the plateau, erosion has broken through the basalt cap in a variety of ways. On the mesas, water-filled sinkholes (lower left) are most likely the result of the collapse of old lava tubes. Along the edges of the mesas (several locations) the basalt seems to be sliding away from the plateau in a series of slices. Water erosion by overland flow is also evident, particularly in canyons where vegetation blankets the drainage channels (bright patterns, bottom of image). However, overland water flow does not extend very far at any location. This entire site drains to local playas, some of which are seen here (dark lakes with bright shores). While the water can reach the playas and then evaporate, what becomes of the eroded rock debris? Wind might excavate some of the finer eroded debris, but the fate of much of the missing bedrock remains mysterious.This anaglyph was generated by first draping a Landsat Thematic Mapper image over a topographic map from the Shuttle Radar Topography Mission, then producing the two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and the right eye with a blue filter.Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972. SRTM topographic data match the 30-meter (99-foot) spatial resolution of most Landsat images and provide a valuable complement for studying the historic and growing Landsat data archive.

  15. Pediatric intensive care in Argentina.

    1993-09-01

    8.2% of the gross domestic product is spent annually on health care in Argentina, a country of 32 million people. There is 1 medical doctor of every 147,000 beds in a total 3180 hospitals. The infant mortality rate in Argentina is 24.5/1000 live births which is high compared to developed countries. Perinatal causes and congenital anomalies are the main cause of death after the neonatal period, and accidents, cardiac disease, and respiratory tract infections are the main causes of death among children over age 1 year. Argentina has approximately 35 pediatric intensive care units (ICU), but 154 of 244 beds are within or near the capital. Only 2 hospitals have pediatric intensive care fellowship programs, so full time dedicated staff is rare. 250 registered pediatricians dedicated to intensive care are in the Argentine Pediatric Society and the nurse/bed ratio is 1:2-1:3. Moreover, the country has neither postanesthesia recuperation units, burn units, chronic ventilation units, nor approved home assistance programs, and intermediate care is not clearly standardized. These inadequacies have led to a shortage of beds and the caring for of critically ill children in general pediatric or emergency wards in hospitals which lack adequate equipment; patients are often discharged inappropriately to clear bed space. Even so, prehospital and emergency room care tends to be provided without the necessary coordination with the pediatric ICU, and structural conditions regarding electrical self-sufficiency, air conditioning, and circulation are met in only few units. Despite the existence of these adverse conditions for the care of critically ill children, a pediatric organ transplant program developed since 1987 has demonstrated 70% to 100% survival rates for 16l orthotopic liver and 9 heart transplants, respectively. Alternatives to improving intensive care in Argentina include optimizing the response of emergency and critical care delivery systems, categorizing hospitals and

    Full Text Available La actividad industrial, de cualquier época, tiene una gran importancia para el hombre, pues al igual que el resto de los procesos económicos, es el reflejo del accionar cotidiano de la sociedad sobre el espacio. Considerando esto, el presente articulo tiene como objetivo presentar al patrimonio industrial como recurso para organizar rutas turísticas que permitan en algunos casos recuperar espacios industriales abandonados o usar establecimientos industriales en funcionamiento pero que pueden incorporarse a este tipo de desarrollo turístico. La creación de rutas turísticas puede permitir la reactivación de las economías locales, por constituirse en definitiva en una nueva actividad económica. Para lograr esto es necesario articular el sector público y el privado. De esta forma es posible, a través de la creación de rutas turísticas del patrimonio industrial, generar un desarrollo turístico local sustentable.

    Full Text Available Se analiza la producción historiográfica argentina en materia de condición femenina y estudios de género de modo integral. El trabajo obra como un estado de la cuestión de la disciplina histórica en este campo y se refiere tanto a los trabajos precursores, anteriores a los años 1980, como a la actividad desplegada por un número cada vez mayor de oficiantes, en el momento en que se inició la legitimación de la historiografía en nuestro país, a medidos de esa década. Coincide la expansión con una serie de fenómenos, externos e internos, entre los que se cuenta la notable renovación y difusión de los estudios feministas, los cambios epistemológicos, las transformaciones de la historia social, el empinamiento internacional de la historiografía de género, a lo que se unen los cambios de la vida política y social argentina con el retorno a la democracia y las modificaciones habidas en el ámbito académico con el ingreso de los estudios de las mujeres y de género. Hay una tentativa conceptual que tipifica esas contribuciones y que pone en evidencia tanto las líneas de fortaleza como las necesidades de auscultamiento histórico que aún aguardan abordajes.This paper is a comprehensive analysis of Argentinean historiographic memory as regards the condition of women and gender studies. It is a state-of-the-art work on the historical discipline in this field and refers both to the precursory works from before the 1980´s and to the activities carried out by an ever-increasing number of agents, at the moment when historiography was legitimated in our country, by the mid 80´s.

  16. Psychiatry and humanism in Argentina.

    Science.gov (United States)

    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.

  17. Argentina to fully privatize state owned YPF

    Energy Technology Data Exchange (ETDEWEB)

    1992-10-05

    Argentina's Congress has voted to fully privatize state petroleum company Yacimientos Petroliferos Fiscales (YPF), a move the government expects to net at least $8 billion. Despite some political opposition, the vote was 119-10 in favor, with one abstention and opposition party members refusing to participate in the vote. Argentina's President Carlos Menem had threatened to authorize YPF privatization by decree if there was no quorum for a vote. YPF is responsible for 40% of Argentina's oil production. The country h as been self-sufficient in crude since 1982. Current production is 563,472 b/d, and proved reserves of oil and gas are valued at $7 billion.

    Argentina and Uruguay are among the countries in which a large proportion of young women smoke. The rate of smokers during pregnancy in both countries is not well known, and data on the characteristics of women who quit smoking during pregnancy compared to those who continue smoking are not available. We conducted a survey including 1512 pregnant women > or = 18 years old (796 in Argentina; 716 in Uruguay), during antenatal visits in public hospitals of large urban regions; 44% of the women in Argentina and 53% in Uruguay had been or were regular smokers. 11% of the surveyed women in Argentina and 18% in Uruguay continued smoking during pregnancy. In both countries, the proportion of women who lived with smokers, allowed smoking at home, and were regularly or always exposed to tobacco smoke indoors, were 49%, 46% and 20% in the subgroup of women who never smoked, 67%, 60% and 32% in those who quit, and 78%, 75% and 52% in those who continued smoking, respectively. The study confirms a serious public health problem in both countries, and documents that environmental exposure persists in subgroups of women, even in those who quit smoking. It is important that the public health sector should provide access to effective programs for smoking cessation, to women who smoke during pregnancy. For the development of a new program, any intervention intending to have at least a moderate and sustainable success, it should seriously consider including components targeting the smoking environment of the pregnant women who smoke.

    In Argentina, vaccines for immuno-preventable diseases are regulated by the national regulatory agency, the Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (the National Administration of Drugs, Food and Medical Devices, or ANMAT) created in 1992 to ensure efficacy and safety of drugs, food and medical devices available in the country, according to Law 16,463 and Decree 150/92. ANMAT has licensed 84 out of 157 vaccines registered in Argentina. Since 1994, ANMAT evaluated, approved and inspected 20 clinical trials with vaccines (1.8% of the 1062 trials approved by the agency since that time). The National System of Pharmaco-vigilance has received 318 communications of eventual adverse post-vaccination events (0.3% of the total). In addition, ANMAT provides support to the National Immunisation Programme. The current procedure is to follow international guidelines in the field, to be prepared for new, rapidly changing scenarios.

    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.

    Full Text Available El consenso sobre los beneficios netos de la presencia de bancos extranjeros en los países emergentes parece en alguna medida debilitarse a raíz de la experiencia de los años noventa, que constituye una fase de fuerte expansión y fortalecimiento de dicha presencia. Distinguiendo entre la presencia y la dominancia en el mercado local por parte de los bancos extranjeros, el presente trabajo analiza la experiencia argentina en el período 1993-2000. Para este fin, se reconstruyo por primera vez la serie completa de los balances bancarios. Los resultados sugieren que la aumentada presencia de bancos extranjeros no ha producido beneficios significativos, mientras que todo el sistema bancario se ha aventajado por el clima de mayor crecimiento y de estabilidad monetaria. Como parte de la estrategia perseguida por parte del poder público, la creciente dominancia de los bancos extranjeros resulta uno de los factores que han empobrecido la biodiversidad de la banca argentina. De todos modos, parte de los problemas que atormentaron a la economía argentina en los años noventa podrían ser considerados más como el resultado de la adopción de una abertura financiera completa que como consecuencia de la dominancia creciente por parte de los bancos extranjeros.

Si bien hay avances realizados en todas las ramas de la biología relacionadas a las lagartijas, los progresos taxonómicos y ecológicos son los más evidentes. Debido a estos progresos, y a la implementación de sustanciales modificaciones conrespecto a la metodología que se utilizara en el año 2000, un grupo de veintisiete especialistas de diferentes instituciones académicas de la Argentina aportaron información biológica, ecológica, geográfica y taxonómica en un taller que permitió reevaluar el estado de conservación de las 256 especies de lagartijas y anfisbenas de la Argentina. Los resultados obtenidos indicanque setenta y ocho especies se encuentran incluidas en la lista roja (una En Peligro, nueve Amenazadas y 68 Vulnerables, 31 Insuficientemente Conocidas y 147 No Amenazadas. 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

    In this article we explore ways in which pro-market discourses have been interpreted in policy initiatives in Argentina since the 1970s.

    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

    2012-07-01

    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.

    Full Text Available This article examines the role of religious actors in sexual politics in Argentina. Sexual politics has become a critical battlefield when it comes to the role of religion in the Argentinean liberal-democratic regime, while gender and sexuality have been the main political targets of religious institutions since the 1980s and 1990s. In this context, progressive legislation on gender, sexual, and reproductive rights was passed, including same-sex marriage and the recognition of transgender identities, despite the opposition of the Catholic Church. Paradoxically, abortion remains largely illegal, allowed only in exceptional circumstances.

    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.

    2016-01-01

    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.

    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.

    1979-01-01

    This case study of Yacimientos Petroliferos Fiscales, the world's first state-owned oil company, traces the development of Argentina's nationalistic petroleum policy from the discovery of oil on state-owned land in 1907 to the present. The focus is on the period prior to 1930, when the institutions and ideologies that have shaped Argentine petroleum affairs became firmly established. A final chapter summarizes developments since 1930, with emphasis on the impact the Argentine experience has had on other oil-producing countries in Latin America. Prior to World War I, Argentine governments gave little attention to the development of petroleum resources, but the wartime economic crisis demonstrated to many prominent political figures the necessity of shifting from dependence on foreign capital and imported fuel toward greater economic self-sufficiency. A key aspect of this new policy was the founding in 1922 of the state oil agency, YPF, which gradually wrested control of oil resources from the provinces in order to establish a vertically integrated, national petroleum industry. Because of its power and influence, YPF survived the 1930 revolution, became the largest economic enterprise in Argentina, and emerged as the very symbol of national economic independence.

    2015-04-16

    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.

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.

    Little is understood about racial/ethnic disparities in infant health in South America. We quantified the extent to which the disparity in preterm birth (PTB; Ecuador are explained by household socio-economic, demographic, healthcare use, and geographic location indicators. The samples included 5199 infants born between 2000 and 2011 from Argentina and 1579 infants born between 2001 and 2011 from Ecuador. An Oaxaca-Blinder type decomposition model adapted to binary outcomes was estimated to explain the disparity in PTB risk across groups of variables and specific variables. Maternal use of prenatal care services significantly explained the PTB disparity, by nearly 57% and 30% in Argentina and Ecuador, respectively. Household socio-economic status explained an additional 26% of the PTB disparity in Argentina. Differences in maternal use of prenatal care may partly explain ethnic disparities in PTB in Argentina and Ecuador. Improving access to prenatal care may reduce ethnic disparities in PTB risk in these countries.

    Full Text Available The behavior of Somontano extra virgin olive oil (obtained from Empeltre and Arbequina olive varieties in the domestic deep frying of prefried frozen potatoes was studied by submitting the olive oil to successive frying cycles. After different frying cycles physico-chemical modifications were monitored through the determination of several chemical (iodine value, total phenols content and physical parameters (viscosity and ultraviolet spectra. An increase in viscosity and a decrease in iodine value, total phenol content and an increase in absorbance at 235, 269 y 280 nm were observed. In general, Somontano olive oil was revealed appropriate for domestic frying because of the high number of frying cycles permitted before reaching the polar compound limit established by Spanish legislation.Se estudió el comportamiento del aceite de oliva virgen extra del Somontano (obtenido a partir de aceitunas de las variedades Empeltre y Arbequina en la fritura doméstica de patatas prefritas congeladas por inmersión, sometiendo al aceite a ciclos sucesivos de fritura.

    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.

    Full Text Available This is a first approach to the application of virtual reconstruction techniques of a colonial house. In Argentina it is still uncommon to perform 3D modeling of archaeological sites and especially in historical archeology. As a first step, we used the Google SketchUp to model the country house located on the banks of the Río de la Plata (Buenos Aires. It has historical significance because it belonged to a Spanish councilman, housed hundreds of slaves and was the place where stayed the troops that carried out the Second British Invasion of Buenos Aires. In this case, the 3D modeling was useful for evaluating the future excavationa and activities of preservation of cultural heritage.

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

    Science.gov (United States)

    Spain, D

    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

    En Julio de 1997 se terminó con la primera parte de la instalación del ``Coronógrafo de Espejo para la Argentina'' en la estación de altura Carlos U. 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.

    2009-12-01

    Full Text Available La práctica del precepto islámico del Ramadán (R, impone a las personas que lo practican importantes modificaciones fisiológicas y psicológicas debido a las restricciones hídricas y dietéticas a las que se ven sometidos, lo que tiene una especial repercusión en el rendimiento físico e intelectual de los estudiantes musulmanes, particularmente en sociedades multiculturales de tipo occidental, en las que no se producen ajustes horarios, en las actividades diarias. 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

  12. Interannual variability of temperature spells over Argentina

    Energy Technology Data Exchange (ETDEWEB)

    Rusticucci, M. M; Vargas, W. M [Departamento de Ciencias de la Atmosfera y los Oceanos, Buenos Aires (Argentina)

    2001-04-01

    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

    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

    Clinical cases of coccidioidomycosis are rare in Argentina and are generally found in the large arid precordilleran area of the country. This study aims to perform a retrospective review of all coccidioidomycosis cases documented in the country from 1892 to 2009, and to describe those occurring in the last 4 years. One hundred and twenty eight cases were documented in the 117 year-period. Since the original description of the disease in 1892 until 1939, only 6 cases were registered; between 1940 and 1999, 59 (6-14/10 yrs) and the remaining 63 (49% of total cases) occurred in the last decade. The median age of 34 patients registered in 2006-2009 was 31 years (range: 7-89), male/female ratio was 1.3:1 and 12 patients were immunocompromised. Twenty-six cases were confirmed by direct microscopy and/or culture whereas the remaining ones by serology. All isolates were identified as Coccidioides posadasii. Thirty patients lived in a vast geographic region with epicenter in Catamarca Valley. Between 2006 and 2009, annual disease incidence rates in Catamarca Province increased from historical values below 0.5/100,000 to 2/100,000 inhabitants. Such increase suggests an emergency of coccidioidomycosis in that region.

    {sup 129}I and {sup 127}I concentrations in animal thyroids coming from several regions of Argentina were determined by accelerator mass spectrometry (AMS) and gas chromatography (GC), respectively. The measured {sup 129}I/{sup 127}I ratios, ranging from 3 Multiplication-Sign 10{sup -12} to 4 Multiplication-Sign 10{sup -10}, are significantly lower than those typical for areas in the northern hemisphere (10{sup -10}-10{sup -7}). The {sup 129}I concentrations show a clear dependence with latitude and season, which can be understood considering tropospheric circulation patterns, possible {sup 129}I sources and regional precipitation rates. - Highlights: Black-Right-Pointing-Pointer This is the first determination of {sup 129}I in thyroids from the southern hemisphere via AMS. Black-Right-Pointing-Pointer Isotopic ratios measured are lower than those found in areas of the northern hemisphere. Black-Right-Pointing-Pointer Two samples represent {sup 129}I/{sup 127}I ratios similar to pre-anthropogenic values.

    Full text: Long-lived {sup 129}I (half-life=15.6 Ma) is produced naturally by irradiation of atmospheric xenon by cosmic neutrons and in the sub-surface by spontaneous fission of {sup 238}U, from which the natural inventory of {sup 129}I has been estimated to be around 50,000 kg, only 140 kg of them corresponds to the hydrospheric inventory. Nuclear tests and accidents have added between 45-130 kg. Apart from a global atmospheric fallout component, {sup 129}I has been released from several nuclear fuel reprocessing plants located in the Northern Hemisphere (ca. 6000 kg) which serve as localized sources in oceanographic-tracer experiments. In this presentation, we report results from a study exploring the presence of {sup 129}I in the Southern Hemisphere by determining {sup 129}I/{sup 127}I isotopic ratios in water samples (rivers, lakes and shallow sea-water) taken at different latitudes in Argentina including Antarctica. The iodine-127 and iodine-129 concentrations were measured via ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and Accelerator Mass Spectrometry (AMS), respectively. Distribution of both isotopes can be understood considering tropospheric circulation patterns, possible sources and regional precipitation patterns. Natural and anthropogenic sources for the Southern Hemisphere and their inventories are discussed. Similar contribution came from natural sources and nuclear tests. Contribution from the nuclear fuel reprocessing plants placed in the Northern hemisphere can be neglected. (author)

    Botulism is a severe neuroparalytic disease caused by Clostridium botulinum toxins. Although the disease is uncommon it is a cause of great concern due to its high rate of mortality. Food-borne outbreaks of botulism occur worldwide and require immediate public health attention and acute care resources. Analysis of outbreaks showed that the food products most often involved were fermented fish products in Alaska; home-canned food, oil preservation and restaurant sauce in the rest of the United States (US) and in London and; and home-canned vegetables, airtight packed food with inappropriate refrigeration, and aerosols in Argentina. The diagnosis is based only on clinical findings matching the disease and previous exposure to suspicious food. Botulism must be immediately identified as even one case suggests the start of an epidemic and should be treated as a public health emergency. Therefore, the purpose of the following review is to recognize the risks associated with the consumption of potentially dangerous foods, and to encourage prevention by seeking to make all public health professionals aware of the dangers of this potentially lethal disease.

    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.

    Based on ethnographic research carried out in the Buenos Aires Metropolitan Area, this paper examines the views of social actors on the psychoanalytically-oriented psychotherapy focused on marginalized populations. From Foucault's perspective on the forms of truth-telling, the aim of this paper is to analyze, as a preliminary research report, treatments according to the native ways of speaking and listening, which dominate the description of therapeutic experiences of patients who come to the treatment without any professional intermediation. The neoliberal transformations of the past decades in Argentina changed both the landscape of the public health system and the daily lives of marginalized people. Considering such changes, this paper examines the ways in which verbal actions (speaking and listening) take place in psychotherapy and mark the course not only of treatments but also the temporal rhythms of their development, and their various levels of efficacy. Finally, the discussion focuses on how ways of speaking and listening in treatments are modeled not only by institutional dynamics but also by the characteristics these verbal activities take in everyday life under the logics of power that prevail over them.

    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

    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.

    Oil pollution in Argentina, at the port of Comodora Rivadavia showed signs of long-term oil pollution of a nature which would not be tolerated in relation to the exploitation of North Sea oil. The field is operated by Yacimientos Petroliferos Fiscales (Argentine), produces 70,000 bbl/day of oil from onshore and offshore wells, and has been in operation since 1907. A very marked ''tideline'' of bituminous oil residues contaminates the harbor installations and completely covers the pebbles, boulders, and rocks in the intertidal region. This material is of a considerable thickness and has completely obliterated any form of littoral marine life in these habitats. The sandy beach does not show signs of accumulative oil, and it is used as an important recreational area. Since seriously oiled seabirds can be seen, it is surprising that Patagonian crested ducks, king cormorants, and kelp gulls occur in large numbers but show little sign of oil contamination. The Magellan penguin, which is much less abundant locally, may have been much more vulnerable to the oil.

    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 In research on CSR in Brazil and Argentina, we saw a huge disparity in the grass-roots of the theme in each country. The hypothesis, stemming from this article, is that the great success of the CSR movement in Brazil and its relatively weak development in Argentina is due to the presence of a hegemonic dispute - in observed dynamic communication - among some segments of business elites regarding the purpose of CSR, present in the Brazilian case and absent in Argentina. This article intends to discuss the concept of hegemonic dispute - highlighting conflict as a fundamental social relationship in the configuration of network topographies of movements to promote CSR in both countries. Such an understanding is essential for professionals and researchers working in the area of ​​organizational communication.

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.

    Full Text Available Cryptosporidiosis is observed in reptiles with high morbidity and considerable mortality. The objective of this study was to achieve the molecular identification of Cryptosporidium spp. in pet leopard geckos (Eublepharis macularius from a breeder colony in Buenos Aires, Argentina. Oocysts comparable to those of Cryptosporidium spp. were detected in three geckos with a history of diarrhea, anorexia and cachexia. Molecular identification methods confirmed the presence of Cryptosporidium varanii (syn. C. saurophilum. This agent was considered to be the primary cause of the observed clinical disease. This is the first description of C. varanii infection in pet reptiles in Argentina.

    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)

    Biologically active solar Ultraviolet-B radiation (UV{sub ery}, 280-315nm) is monitored in Cordoba, Argentina (31{sup o}24'S, 64{sup o}11'W, 400m a.s.l) using the Yankee Environmental Systems (YES) pyranometer, model UVB-1. Measurements of the solar broadband UV-B irradiances are presented for the period of November 1998-December 1999. The site selected for the measurements represents semi-urban conditions and is along the most frequent wind direction (NE-SW) with reference to downtown, following the direction of prevailing winds. For clear sky days, the measurements are in good agreement with results of a radiative transfer model. However, examination of the record of solar ultraviolet measurements showed substantial reduction of the UV-B radiation on days with high levels of air pollution, which are associated with high concentration of particulate matter. Particulate matter is the only pollutant that surpasses the air quality standard several times during the year in Cordoba City. In this work, we investigate the daily variation of the UV-B radiation to assess its response to air pollution, physical variables, and meteorological factors. The main findings are that tropospheric aerosol is the most important UV-B attenuating factor (up to 40%), whereas tropospheric ozone and other UV absorber air pollutants like SO{sub 2} are not important. The results are consistent with the fact that pollution in Cordoba has mostly primary character with CO, NO{sub x}, and PM{sub 10} being the most important air pollutants. The UV-B radiation correlates well with simultaneous records of total radiation, but the reduction factors reflect stronger effects on the UV radiation than on total radiation. (Author)

A partir de aportes conceptuales de Beckford, el trabajo se propone distinguir diversidad de pluralismo religioso y, atentos a la perspectiva de las "economías religiosas" propuesta por Stark y Iannaccone, se considerará al grado de regulación del mercado religioso como una variable de principal importancia para entender los cambios, tomando en cuenta tanto la acción gubernamental como la regulación social. Estas ideas se ejemplificarán examinando el aumento del movimiento social evangélico - más allá de su prioridad meramente religiosa - que lucha por derechos religiosos igualitarios en una situación de supuesto pluralismo religioso en Argentina.The paper argues that in order to understand the current state of the Argentine religious field and the development of new religions it is necessary to include the social resistance they encounter into our analysis. It criticizes the widespread idea that after the erosion of Catholic monopoly a religious market is effortlessly formed and pluralism simply ensues. Drawing on recent work by James Beckford, it argues that religious diversity does not necessarily entail pluralism (its positive evaluation. Emphasizing the idea central to the religious economies paradigm (Stark, Iannaccone that the degree of regulation of a religious market is always a crucial variable to consider, it follows Grim and Finke's multidimensional approach to regulation, taking into account governmental as well as social regulation.

    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.

    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.

    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.

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.

    The Atlantic Forest represents one of the global priority eco-regions for biodiversity conservation. In Argentina, this is represented by the Paranense Forest, which occupies much of the Misiones Province. In this paper, an updated list of land mollusks from Misiones Province is presented, and its species richness was evaluated comparing protected and unprotected areas. For this, we reviewed La Plata Museum Mollusk Collection, updated the literature review, and developed some field work between 2009 and 2010. For the areographic work, a grid (50 x 50 km) was applied to a Misiones province map. In this region, large areas of native vegetation constituting the Paranaense Forest still persist, and include protected areas such as the Iguazú National Park and Puerto Peninsula Provincial Park. These areas have been the most explored at the malacological level (both terrestrial and aquatic environments), a fact that is consistent with the greater number of records found, which may also be the explanation for the highest number of species recorded in the region. A database containing 497 records was compiled. The number of species occurring in this Province was increased from 28 to 56; 11 of which were exotic species. A total of 38 of the species occurred in protected areas and 53 in unprotected areas; and 25 species were micro-mollusks. Orthalicidae was the family with the highest species number (10) and the widest distribution, occupying 16/20 sampling units. Megalobulimus was the genus found in a greater number of sampling units (14/20). The highest values of specific richness of land gastropods were found in Northern Misiones (R=32). This richness was similar to that previously reported for the Tucumán Province, although species occurring in both provinces were mostly different. The richness in Misiones Province border areas, as the Republic of Paraguay and the state of Santa Catarina (Brazil), was about twice that found in the province. The present study showed the

    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.

    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)

    Full Text Available Over 175 years ago Charles Robert Darwin arrived in Argentina to find a bare and boundless plain, the brave centaur called "gaucho", Quaternary fossils everywhere, and a society strikingly strange and aggressive to the British eyes of the young traveller. Although the voyage aboard HMS Beagle was the indispensable way towards increasing his stature as a biologist, Lyell's work awakened an inquisitive geological mind which allowed him to wonder at the splendour of the Andes. Forty-two years after having concluded his voyage on the Beagle, the National Academy of Sciences of Argentina appointed him as an Honorary Member. This must be interpreted as an early gesture of recognition -in the context of those times- to the magnificence of his scientific work.

    Full Text Available A total of 143 Mycobacterium bovis isolates of pigs, from the most productive swine area in Argentina, were typed by spoligotyping. Twenty-two different spoligotypes were identified, and 133 (93% isolates were grouped into 12 clusters. One of them, designed SB0140, was the most frequent because it held 83 (58% isolates. This spoligotype also grouped 362 (43% out of 841 isolates from previously typed cattle and, thus, constitutes the most frequent in our country. In addition, 135 (94% isolates revealed spoligotypes identical to those of cattle, showing an epidemiological link. On the other hand, there were seven novel spoligotypes, six of which were also unique since they had only one isolate each. This study aimed to identify the spoligotypes of M. bovis isolated from pigs to contribute to a better understanding of the distribution of bovine tuberculosis in the main productive area of Argentina.

    The Argentina National Commission on Space Activities (CONAE) has been forecasting the UV Index for solar risk prevention from November 1996 up to the present. It is based on a parametric atmospheric radiative transfer calculation, including mainly the ozone attenuation from TOMS/NASA data and the altitude (pressure) and coordinates of the selected site. Daily predictions, for various locations of Argentina as well as for other countries are published via the web at www.conae.gov.ar. We present in this work the improved version of the CONAE UV Index using the TUV program developed by Madronich (www.acd.ucar.edu), with the inclusion of effective aerosol data estimated for each site.

    Avian influenza (AI) is an exotic disease in Argentina. A surveillance program for AI was conducted in backyard poultry during 1998-2005 in two regions: 1) region A, which included the avian population in the provinces that border Brazil, Bolivia, and Paraguay, and 2) region B, which included the rest of the provinces of the country. More than 8000 serum samples were tested for antibodies by enzyme-linked immunosorbent assay and/or agar gel immunodiffusion tests, and more than 18,000 tracheal and cloacal swabs were tested for virus by isolation in embryonated specific-pathogen-free eggs. This study was part of the AI prevention program in Argentina, which includes other avian populations such as commercial poultry and all the controls for importation and exportation of live birds. The results from backyard poultry were negative for AI.

    In the central area of Argentina, the epidemiological and molecular characteristics of Chlamydophila pneumoniae infections in reptiles are still unknown. A nested polymerase chain reaction of the rpoB gene was used to detect C. pneumoniae in cloacal swab samples from 19 reptiles at a recreational area. Eleven (57.89%) reptiles were positive; the sequencing and phylogenetic analysis confirmed the presence of this bacterium. Neither C. pneumoniae DNA in the caregivers pharynges nor IgM antibodies anti-C. pneumoniae in their serum samples were detected; however, caregivers presented very high titers of IgG anti-C. pneumoniae. The detection of C. pneumoniae DNA in reptiles demonstrated the circulation of this agent in the recreational area and could be responsible for the exacerbated immune response of the personnel handling the reptiles, which suggests a potential zoonotic cycle. This is the first report of the detection of C. pneumoniae in reptiles in Argentina.

    esenciales para el diagnóstico, clasificación y tratamiento del asma bronquial y dentro de ellos la medición del flujo expiratorio máximo proporciona un valor cuantitativo de la obstrucción de las vías aéreas. Objetivo: Precisar las modificaciones del flujo expiratorio máximo en el tratamiento intercrisis del asma bronquial con intal y ketotifeno. Métodos: Se realizó un estudio en dos etapas, la primera descriptiva en la que se incluyeron los pacientes de 15 años y más con diagnóstico de asma bronquial y pertenecientes al Consultorio Médico de Familia # 26 del Policlínico área V del Municipio Cienfuegos. La muestra quedó constituida por 37 pacientes, a los que se les aplicó un formulario de datos donde se incluía la edad, sexo, características clínicas de su enfermedad y el tratamiento en ese momento. En la segunda etapa se crearon dos grupos seleccionados por el método aleatorio simple. El primero recibió tratamiento con intal spray (4 aplicaciones/día y el segundo con ketotifeno (tab. 1 mg. /2tab al día. Se realizaron mediciones del flujo expiratorio máximo a los tres, seis, nueve y doce meses de implementado el tratamiento. Resultados: Prevalecieron las edades de 15 - 24 años y de 25 - 34 años y el sexo femenino, el salbutamol spray fue el más utilizado en los tratamientos anteriores, inicialmente el mayor número de asmáticos fue clasificado como moderados y al finalizar el 12 mo mes el 72.9 % del total de la muestra se comportaba como ligeros; con ambos tratamientos se mejoraron los valores del flujo expiratorio máximo, aunque el grupo de pacientes que recibió tratamiento con intal mostró una mejoría mucho más rápida. Conclusión: Aquellos pacientes que utilizaron intal tuvieron una elevación más rápida del flujo expiratorio máximo.

    Until early 1998 the presence of Aedes albopictus had never been detected in Argentina. During April of the same year, few individuals of this species were recorded in 33 breeding sites found in 25 out of 161 inspected houses in the city of Eldorado, Province of Misiones. The homogeneous spatial distribution of the proliferation foci suggests the existence of a generalized infestation in this locality during the study period.

    Background The Fogarty International Center (FIC) of the United States National Institutes of Health includes the International Training and Research in Environmental and Occupational Health (ITREOH) Program. The “International Training Program in Environmental Toxicology and Public Health” Center, funded in 2002 is based at the University of California, Davis, and is part of the ITREOH group of Centers. It has major efforts focused at the public universities in Montevideo, Uruguay, and Salta, Argentina. Results Training and research efforts in Salta begun in 2005 in the College of Engineering. A donated used real-time PCR machine was the starting point and the initial FIC support was instrumental to face other problems including physical space, research projects and grants, trainees, training, networking, and distractions/opportunities in order to develop local capacities in Environmental Engineering using modern methodology. After six years of successful work, the Salta center has become a reference Center in the field, and is still growing and consolidating. Conclusions This program has had a significant impact locally and regionally. The model used in Argentina could be easily adapted to other fields or types of projects in Argentina and in other developing countries. PMID:22467330

    On October 21 and 22, 1998, the Center for International Security Affairs at Los Alamos National Laboratory and the Center for Global Security and Cooperation at Science Applications International Corporation hosted the first of a series of work-shops on states that have chosen to roll back their pursuit of nuclear arms. 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.

Este artículo sostiene que el kirchnerismo no es un modo coherente de gobierno que haya roto con el neoliberalismo, como suele indicarse en la literatura académica, sino más bien, un acto de equilibrio entre los intereses económicos soberanos de las corporaciones argentinas y las demandas del sistema financiero internacional que las economías semiperiféricas confrontan en la red de integración global.

    AIM: To estimate the progression of the hepatitis C virus(HCV) epidemic and measure the burden of HCVrelated morbidity and mortality. METHODS: Age- and gender-defined cohorts were used to follow the viremic population in Argentina and estimate HCV incidence, prevalence, hepatic complications, and mortality. The relative impact of two scenarios on HCV-related outcomes was assessed:(1) increased sustained virologic response(SVR); and(2) increased SVR and treatment.RESULTS: Under scenario 1, SVR raised to 85%-95% in 2016. Compared to the base case scenario, there was a 0.3% reduction in prevalent cases and liverrelated deaths by 2030. Given low treatment rates, cases of hepatocellular carcinoma and decompensated cirrhosis decreased < 1%, in contrast to the base case in 2030. Under scenario 2, the same increases in SVR were modeled, with gradual increases in the annual diagnosed and treated populations. This scenario decreased prevalent infections 45%, liver-related deaths 55%, liver cancer cases 60%, and decompensated cirrhosis 55%, as compared to the base case by 2030. CONCLUSION: In Argentina, cases of end stage liver disease and liver-related deaths due to HCV are still growing, while its prevalence is decreasing. Increasing in SVR rates is not enough, and increasing in the number of patients diagnosed and candidates for treatment is needed to reduce the HCV disease burden. Based on this scenario, strategies to increase diagnosis and treatment uptake must be developed to reduce HCV burden in Argentina.

En este nuevo escenario, las pequeñas y medianas empresas (PYMES tuvieron un notable desempeño económico y recuperaron el dinamismo que habían perdido en la década anterior. No obstante, la limitación de acceso a los mercados de crédito por parte de las PYMES en Argentina es un fenómeno ampliamente reconocido, que compromete las posibilidades de crecimiento y expansión de estas empresas. Este trabajo analiza el crédito bancario efectivamente otorgado a las PYMES en el periodo 2002-2009 en Argentina. Se concluye la necesidad de intervención y regulación del Estado argentino en el mercado bancario, así como la redefinición de las políticas de crédito de entidades públicas y otras políticas focalizadas para mejorar el financiamiento de estas empresas.

    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.

    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

Ambas vacunas mostraron una tasa equivalente de inmunogenicidad ligeramente superior al 95.5%, que es la eficacia estimada para Candid #1 en estudios previos. No se observaron eventos adversos graves relacionados con la vacuna. Los eventos adversos generales considerados relacionados fueron de escasa significación clínica y de resolución espontánea o con tratamiento sintomático; se presentaron en los receptores de ambas vacunas en tasas equivalentes (29.9% para la vacuna fabricada en la Argentina y 35.0% para la fabricada en EE.UU., e incluyeron: cefalea, decaimiento, mialgias, plaquetopenia leve (< 150 000 plaquetas/mm³, náuseas y/o vómitos, leucopenia leve (< 4 000 blancos/mm³, fiebre, dolor retroocular, mareos, microhematuria, lumbalgia y exantema.

    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.

    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.

    Full Text Available En este trabajo se evalúan los efectos de las modificaciones antrópicas sobre la recarga del acuífero freático en una zona medanosa. 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.The aim of this paper is to evaluate the effects of the anthropogenic modifications on the aquifer recharge in coastal dunes zones. The study area is San Clemente del Tuyú, at the marine littoral of the province of Buenos Aires, where the land use has generated significant modifications in the

    Dusky dolphin (Lagenorhynchus obscurus) acoustic sounds were characterized by analyzing narrowband recordings [0-16 kHz in New Zealand (NZ) and 0-24 kHz in Argentina], and sounds in broadband recordings (0-200 kHz) were compared to their counterparts in down-sampled narrowband recordings (0-16 kHz). The most robust similarity between sounds present in broadband recordings and their counterparts in the down-sampled narrowband recordings was inter-click interval (ICI); ICI was therefore primarily used to characterize click sounds in narrowband recordings. In NZ and Argentina, distribution of ICIs was a continuum, although the distribution of ICIs in NZ had a somewhat bimodal tendency. In NZ, sounds that had smaller mean ICIs were more likely to have constant ICIs, and less likely to have increasing or decreasing ICIs. Similar to some other delphinids, dusky dolphins may use single, short duration sounds that have a constant ICI and closely spaced clicks for communication. No whistles were documented at either study site. Temporally structured sequences of burst pulses (i.e., sounds with ICI < about 10 ms) also occurred at both study sites, and these sequences contained 2-14 burst pulses that appeared closely matched aurally and in spectrograms and waveforms.

    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.

    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.

    Full Text Available The Preandean geological configuration of the eastern North Patagonian Massif is established through the use of geological and geophysical analysis. The positive gravity anomalies located near the Atlantic coast are due to 535 and 540 Ma old rocks belonging to the Pampean Orogeny (Precambrian–middle Cambrian, which are widely recognized in central and northern Argentina. The Famatinian Cycle (Ordovician–Devonian is represented by a Silurian–Devonian marine basin equivalent to those of eastern-central Argentina and South Africa, and which was deformed at the end of the Devonian by an ∼E–W to WNW–ESE compressional event, part of the Famatinian Orogeny. Containing strong gravity gradients, the NW–SE belt is coincident with fault zones which were originated during the Gondwanide Orogeny. This event also produced NW–SE overthrusting of the Silurian–Devonian sequences and strike-slip faults that displaced blocks in the same direction. This deformation event belongs to the Gondwanide Orogeny that includes movements related to a counterclockwise rotation of blocks in northern Patagonia. The strong negative anomalies located in the western part of the area stem from the presence of rocks of the Jurassic Cañadón Asfalto basin interbedded in the Marifil Complex. These volcaniclastic sequences show mild deformation of accommodation zones in a pre-Jurassic paleorelief.

    Full Text Available Desde principios de la década de 1990 hasta el año 2002, tuvo lugar en Argentina un intenso proceso de extranjerización de la cúpula del empresariado en todos los sectores de la economía. Como resultado, se ha producido una pérdida de densidad y peso económico, social y político del gran empresariado de capital nacional. Este ensayo ofrece un panorama cuantitativo de la extranjerización en el segmento de las compañías de mayor tamaño y de las diferencias entre las de capital nacional y extranjero en materia de costos de producción y financiamiento. Luego se analiza de un modo sistemático y general la trayectoria declinante de las grandes firmas y conglomerados locales y sus causas. Por último, se proponen algunas reflexiones acerca del significado histórico del fenómeno de la extranjerización del capital en Argentina en general, así como del que puede atribuirse a la extranjerización que tuvo lugar en la década de 1990.

    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 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.

    Full Text Available La leishmaniasis tegumentaria ha experimentado en Argentina, desde 1985, un incremento de casos totales, de la frecuencia, intensidad y distribución de brotes epidémicos, y de la incidencia relativa en mujeres y en niños. Es necesario caracterizar los nuevas circunstancias de transmisión generadas en las últimas décadas para el diseño de estrategias apropiadas de control. Con dicho objeto, basados en indicadores epidemiológicos, entomológicos y en el análisis cualitativo de imágenes satelitales, se describen cuatro brotes epidémicos tomados como casos de estudio: Urugua-í (2004, Esperanza (1998, Alberdi (2003 y Monteros-Simoca (2004. A partir de dichas descripciones se caracterizaron cuatro ciclos: a silvestre con transmisión en vegetación primaria o residual; b silvestre con transmisión eventual peridoméstica por alteración de parches de vegetación residual; c silvestre con transmisión peridoméstica por contigüidad con vegetación residual; d peridoméstico en ambientes rurales, periurbano ruralizado o interfase urbano-rural. Todos los brotes epidémicos ocurridos desde 1985 se correspondieron con uno de estos ciclos, demostrando ser hasta el momento una tipificación abarcativa de la transmisión de leishmaniasis tegumentaria en la Argentina. De esta manera se categorizaron cuatro patrones epidémicos en el país, destacando a su vez la utilidad del análisis cualitativo, de datos de terreno e imágenes satelitales, como herramientas para comprender la epidemiología de la enfermedad y poder desarrollar medidas adecuadas de prevención y control.The total cases of tegumentary leishmaniasis in Argentina increased since 1985, as the frequency, intensity and geographic distribution of the epidemic outbreaks, and the relative incidence in women and children.

    2011-10-01

    Species of Philornis Meinert, 1890 (Diptera, Muscidae) are Neotropical dipterans that include species with parasitic larvae which feed on nestling birds. To date, all Philornis species that have been recorded from Argentina have parasitic subcutaneous larvae. Here, for the first time for Argentina, we report the finding of Philornis downsi Dodge & Aitken, 1968, a fly with a nest-dwelling, semi-haematophagous larva. This record, from the humid Chaco ecoregion of Argentina in the nest of a saffron finch Sicalis flaveola pelzelni Sclater, substantially extends the known distribution of this species. We also report the consensus sequences of the internal transcribed spacer 1 (ITS1) and ITS2 regions of three of the specimens for future reference and comparison. Further investigation is needed to determine whether Argentina is part of the historical range of P. downsi or, alternatively, represents a recent expansion of its range, perhaps due to climatic changes or other factors of global environmental variation.

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.

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.

    The objective of this study was to examine the alkalithermophilic actinomycete communities in the subtropical environment of Jujuy, Argentina, characterized by sugarcane crops. Laceyella putida, Laceyella sacchari, Thermoactinomyces intermedius, Thermoactinomyces vulgaris and Thermoflavimicrobium dichotomicum were isolated on the media with novobiocin, from sugar cane plants and renewal rhizospheres, and grass and wood soils. Soil pH was almost neutral or lightly alkaline, except for grass soil acidified by lactic liquor. A smaller number of actinomycetes was found on the living plants and bagasse (recently obtained or stored according to the Ritter method) with respect to decomposed leaves on the soil. Thermophilic species of Laceyella, Thermoactinomyces, Thermoflavimicrobium, Saccharomonospora, Streptomyces and Thermononospora were isolated on the media without novobiocin, from composted sugar cane residues. Air captured near composted bagasse piles, contained alkalithermophilic actinomycete spores.

    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.

    The research work produces a contrasted quantification of the thermal performance of inhabited dwelling houses built in different neighborhoods of San Juan, Argentina. They correspond to five prototypes aimed at families with low and medium income levels, massive spread in their versions with two or three bedrooms. From all of them it can be obtained yearly energy consumption indexes per unit area, under homogeneous conditions respect to minimal thermal comfort levels and inhabitant behaviors. The evolution of their inner temperatures and relative humidity with and without auxiliary thermal conditioning is analyzed. Conclusions assess the deficit level of the studied prototypes contrasted to international standards and the global valuation of the impact on the sectorial annual energy consumption caused by them.

    We analyse the all-sky Leiden/Argentina/Bonn HI survey, where we identify shells belonging to the Milky Way. We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given properties of HI shells. We found 333 shells in the whole Galaxy. The size distribution of shells in the outer Galaxy is fitted by a power law with the coefficient of 2.6 corresponding to the index 1.8 in the distribution of energy sources. Their surface density decreases exponentially with a scale length of 2.8 kpc. The surface density of shells with radii >= 100 pc in the solar neighbourhood is around 4 per kpc^2 and the 2D porosity is approximately 0.7.

    The permanent update of mental health professionals has become an actual requirement. Nowadays, there is an important concern to offer to the patient's problems the best therapeutics that respond to their specific needs. The well known Clinical Guides are tools to address that objective. In the United Kingdom, USA, Canada, Germany, the Netherlands, France and some Latin American countries different organisms have been created with the objective to develop clinical guidelines. In Argentina, the situation is precarious. In Buenos Aires City, there are few efforts in such direction. An heterogeneous group of factors (social, economic, corporative, theoretical-academic or curricular and ideological) seem to difficult the development of a project of these characteristics, adapted to this population.

    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.

    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)

    2015-09-01

    The ecology of Amblyomma tonelliae (Ixodida: Ixodidae), including its seasonal distribution and the development periods of each stage, was investigated during a study carried out over two consecutive years in northwestern Argentina. In addition, the genetic variation of this tick was studied through analyses of 16S rDNA sequences. Amblyomma tonelliae has a 1-year lifecycle characterized by a long pre-moult period in larvae with no development of morphogenetic diapause. Larvae peak in abundance during late autumn and early winter; nymphs peak in abundance in spring, and adults do so from late spring to early summer. Amblyomma tonelliae shows a marked ecological preference for the driest areas of the Chaco ecoregion. In analyses of 16S rDNA sequences in genes from different populations of A. tonelliae, values for nucleotide diversity and the average number of nucleotide differences showed genetic diversity within this species to be low. No significant differences were found in comparisons among populations.

    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.

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.

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 trabajo toma distancia de los estudios que enfatizan la importancia de la dimensión política para explicar el proceso de constitución y reproducción de esta elite económica, enfatizando en cambio los determinantes económicos de este proceso. El ensayo no aporta nueva evidencia empírica, sino una reflexión a partir de la literatura existente.

    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

    Full Text Available La primera agencia ambiental estatal fue tempranamente creada en Argentina con el retorno a la democracia en 1973 y tras la Conferencia de Estocolmo de 1972. No obstante, la creación de instituciones estatales ambientales ha distado de ser incremental y sólo comenzó a ganar vigor en la década de 1990. Simultáneamente, las organizaciones sociales ambientalistas emergieron en sucesivas oleadas desde mediados de los años 1960 hasta nuestros días. Este trabajo reconstruye el surgimiento de las instituciones ambientales y la forma en que los actores estatales y sociales han interactuado a lo largo del proceso. Argumentaremos que el ambientalismo social y la creación de instituciones estatales ambientales recorrieron caminos paralelos y no tuvieron mayor contacto hasta el nuevo milenio, cuando un nuevo tipo de ambientalismo social logró impactar en la agenda gubernamental a partir de una serie de conflictos ambientales. Argumentaremos, también, que el recorrido del ambientalismo estatal y social en Argentina debe entenderse a la luz de la influencia internacional (tanto ideológico-normativa como financiera y de la dinámica del régimen político. Respecto de esta última, mostraremos que tanto el cambio de régimen como cambios institucionales dentro del régimen fueron favorables al desarrollo de una agenda pública ambiental y de su encuentro con la agenda gubernamental.

    Hepatitis B virus (HBV) infection is a major public health problem worldwide. The aims of this study were to describe the molecular epidemiology of HBV in the Province of Misiones, Argentina and estimate the phylodynamic of the main groups in a Bayesian coalescent framework. To this end, partial or complete genome sequences were obtained from 52 blood donor candidates. The phylogenetic analysis based on partial sequences of S/P region showed a predominance of genotype D (65.4%), followed by genotype F (30.8%) and genotype A as a minority (3.8%). At subgenotype level, the circulation of subgenotypes D3 (42.3%), D2 (13.5%), F1b (11.5%) and F4 (9.6%) was mainly identified. The Bayesian coalescent analysis of 29 complete genome sequences for the main groups revealed that the subgenotypes D2 and D3 had several introductions to the region, with ancestors dating back from 1921 to 1969 and diversification events until the late '70s. The genotype F in Misiones has a more recent history; subgenotype F4 isolates were intermixed with sequences from Argentina and neighboring countries and only one significant cluster dated back in 1994 was observed. Subgenotype F1b isolates exhibited low genetic distance and formed a closely related monophyletic cluster, suggesting a very recent introduction. In conclusion, the phylogenetic and coalescent analyses showed that the European genotype D has a higher circulation, a longer history of diversification and may be responsible for the largest proportion of chronic HBV infections in the Province of Misiones. Genotype F, especially subgenotype F1b, had a more recent introduction and its diversification in the last 20years might be related to its involvement in new transmission events.

    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)

    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

    Full Text Available Las relaciones argentino-iraníes se encuentran, a nivel político, en el punto más bajo de su historia. 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.

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.

    Full Text Available Over the past two decades, indigenous issues have become a major concern for different countries all over the world. 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.

    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.

    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. En 2000 se notificaron sólo 10 casos de meningitis en esas edades (0.29/ 100.000.

    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.

    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.

    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.

    An observational, descriptive study was conducted to evaluate compliance with certain traffic regulations in city of Santa Fe, Argentina, and compare these with measurements taken in prior years. During January 2-4, 2006, at 13 sites across the city, compliance with the following traffic rules was measured: for car drivers: seat belt use and restricting minors to the rear seat; and for motorcycle drivers: helmet use and not carrying a minor on board. At total of 4 173 cars and 1 013 motorcycles were observed. Only 9% of the car drivers wore seatbelts. Of the 246 cars carrying minors, 56% had a minor in the front seat. Regarding the motorcycles drivers, only 12% wore a helmet and 6.7% had a child on board. When these observations were compared with those of the previous five years, findings showed that over the past three years compliance rates had decreased. The results of this study suggest that most drivers in city of Santa Fe do not obey the stated traffic laws. In order to reduce the high rate of mortality from traffic accidents, in addition to legislation and public-awareness campaigns, a system for enforcing compliance is needed.

  17. Peregrinos católicos y religiosidad popular en Argentina

    2010-12-01

    Full Text Available La religiosidad hoy nos provoca y nos hace pensar en los territorios sagrados no como algo turístico o peculiar, sino como una heterogénea espacialidad donde se construyen mapas híbridos como consecuencia de la diversidad de devociones. 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.

  18. Experience with two pipeline river crossings in Argentina

    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)

    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.

    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.

    An epidemiological study of brucellosis was carried out in 516 goats and mixed flocks (goat/sheep) from the three agro-ecological regions of Formosa province, Argentina. Serum samples from a total of 25401 goats and 2453 sheeps were analyzed using buffered plate agglutination test (BPAT) and complement fixation test (CFT). Bacteriological and PCR analyses on milk samples from goats in three flocks with a history of brucellosis and recent abortions were also performed. Brucellosis was detected in four of the nine departments of the province with an overall prevalence of 2% and an intra-flock prevalence ranging between 1% and 40%. The proportion of infected flocks was 3.6%, 12% and 36% for the eastern, central and western regions, respectively. Brucella melitensis bv. 1 was isolated efrom goats for the first time in the province. The expected fragments of 827bp from the omp2ab gene (Brucella spp.) and 731bp from the insert IS711 (B. melitensis) were amplified by PCR. Detection of antibodies by BPAT and FCT in sheep cohabiting with goats suggests that infections could have been caused by B. melitensis, posing an additional risk to public health. Control and eradication programs for brucellosis should consider mixed flocks as a single epidemiological unit. The results indicate that brucellosis by B. melitensis bv1 is highly endemic in the central and western regions of Formosa province.

    2014-01-01

    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. This contribution constitutes the first reconstruction of a Cretaceous aquatic habitat for southern South America.

La primera es como cohesión grupal que define un “nosotros” y un “ellos”, una forma de comportamiento entendido como “correcto”, y toda una concepción cultural “clasista” que abarca y subyace elementos ideológicos y políticos. O sea, esta “memoria” es central a la existencia de una identidad determinada. La segunda es que estas prácticas y memorias constituyen la materia prima del acervo de experiencia que permite la continuidad de luchas y actividades en pos de intereses clasistas. Más allá de su resultado concreto, cada lucha prefigura y contribuye a las luchas posteriores convirtiendo la memoria de haber luchado en un elemento poderoso de la percepción clasista. Este artículo examina los contrastes entre la memoria “oficial” y la memoria que construyen cinco trabajadores de sus vivencias durante la dictadura militar argentina de 1876 a 1983.

    2015-01-01

    A population survey was conducted in 9 provinces of Argentina in 2012 aimed at determining the level of knowledge of diabetes mellitus and the risk of developing the disease. This was a cross-sectional study based on the general population and including men and women aged 18-70 years from all socioeconomic backgrounds. Results showed that 30.5% of participants without diabetes mellitus were at risk of developing the disease. Fifty-nine percent of participants had a body mass index = 25 kg/m2. Forty-nine percent did less than 30 minutes of daily physical activity. Only 34% of the population ate fruits and vegetables every day. Ninety-eight percent of participants had once heard of diabetes, and 67% defined it as a severe or very severe disease. In view of the findings resulting from this survey, healthcare services are expected to improve prevention and effective control of cardiovascular risk factors as well as to enhance preventive actions in order to encourage the adoption of healthier lifestyles from an earlier age and to achieve greater knowledge not only among patients living with diabetes, but also within the general population.

    Full Text Available Este artículo reconstruye la genealogía del pensamiento nacionalista católico en Argentina para mostrar su influencia en el gobierno del General Onganía dentro de un ambiente en que la cuestión nacional se había instalado como tema central en el debate político. La hipótesis central es que existió una fuerte autonomización de lo político con relación a lo económico que generó un ambiente discursivo en el que fue posible la recepción del discurso de Onganía el cual, en última instancia, era el resultado de una simbiosis entre el nacionalismo católico y el liberalismo económico, recuperando una tradición que habían inaugurado los intelectuales de La Nueva República en los años 20. Se concluye que el corporativismo de Onganía no significó una propuesta política novedosa.

Methods: We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given properties of HI shells. Results: We found 333 shells in the whole Galaxy. The size distribution of shells in the outer Galaxy is fitted by a power law with the coefficient of 2.6 corresponding to the index 1.8 in the distribution of energy sources. Their surface density decreases exponentially with a scale length of 2.8 kpc. The surface density of shells with radii ≥100 pc in the solar neighbourhood is ~4 kpc-2 and the 2D porosity is ~0.7.

    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.

    In Argentina, data on the presence of members of the genus Bartonella is scarce. To increase knowledge about these zoonotic pathogens in this country, the presence and variability of Bartonella spp. was investigated in cats and dogs from Buenos Aires. Bartonella spp. was detected in 17.8% of cats, while all dogs tested negative by PCR and Reverse Line Blot. B. henselae was the most frequent species, being detected in 11.9% (14/101), while B. clarridgeiae was found in only 5.9% (6/101) of the cats. Afterwards, B. henselae isolates and positive blood samples were characterized by Multiple Locus Sequence Typing (MLST) and Multiple Locus Variable Number Tandem Repeats Analysis (MLVA). As result, four different MLST sequence types (ST) and eight MLVA profiles were identified. ST 1 was the most frequent variant found in cats, followed by ST 8. Interestingly, some of the MLVA profiles that were detected in this study have been previously associated with human disease, and represents a potential risk of infection. Veterinarians and physicians should consider the presence of these emerging pathogens in their diagnostic routine.

    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.

    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.

    Full Text Available The Quaternary infilling of a circular structure located in Bajada del Diablo, Chubut Province, Argentina has been proposed as a crater strewn field in previous studies. Here we report the finding of about 65 microspherules collected in a trench excavated in the center of the structure. The majority of hand-picked specimens are single, but some of them exhibit compound forms. The single specimens are spherical with a mean size of 137 μm, whereas the more complex samples show peduncles and drop shapes. Dendritic crystal growth is recognized in the internal structure of some broken microspherules. Preliminary chemical composition from the surface and center of microspherules was determined by energy dispersive spectrometry employing EDS. Quantitative EMPA and XRD analysis indicate that the microspherules are mainly composed of Fe and O with magnetite, Fe0 with subordinate wüstite. Following consideration of possible anthropogenic and volcanic origins, these spherulites are ascribed to an extraterrestrial input. An accumulation rate of 47 microspherules per m2/yr is estimated for the studied sediments. This value is two orders of magnitude higher than the reference flux for cosmic dust estimated for the last 1 Ma in the Transantarctic Mountains. The microspherules might have been generated as a byproduct of asteroid entry in the atmosphere.

    Full Text Available El modelo de Basu y Van (1998 plantea a nivel teórico la llamada hipótesis de lujo según la cual los hogares están comandados por padres altruistas y pobres que recurren al trabajo infantil como estrategia de escape de la pobreza. Según este enfoque, si la economía está en una situación de equilibrio múltiple, puede ocurrir que la aplicación efectiva de las leyes que prohíben el trabajo infantil provoque un empeoramiento del bienestar de los hogares y aumente la pobreza. Con datos de la Encuesta de Actividades de Niños, Niñas y Adolescentes realizada en la Argentina en 2004, se explora empíricamente la hipótesis de padres altruistas examinando en qué medida la pobreza monetaria y las privaciones materiales pueden considerarse determinantes de la participación económica de niñas, niños y adolescentes.

    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.

    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.

    Full Text Available Resumen El propósito de este trabajo es explorar el perfil del litigio por el acceso a la atención de la salud, tramitado ante la Corte Suprema de Justicia Argentina, y reflexionar sobre su potencial para influir sobre la equidad y el derecho a la salud, en el marco de un proceso de crecimiento de la judicialización. Se llevó a cabo un análisis documental de 125 litigios con sentencias dictadas entre 1994 y 2013. Se observó una preeminencia de la reclamación individual (88% reclamantes personas físicas individuales, y de reclamantes afiliados a la seguridad social o a seguros privados (64%, con un esquema típico del derecho privado (87% reclama cobertura de un servicio médico. El 75% de los fallos ordenaron brindar los servicios de salud reclamados, sin visibilizar los fallos del sistema de salud, ni ordenar acciones para promover la equidad y garantizar el derecho a la salud, que alcancen a otras personas sometidas a la misma situación que el reclamante. La judicialización, hasta el momento, no está promoviendo activamente la equidad, el derecho a la salud y el diálogo interinstitucional.

    Full Text Available Este trabajo analiza un episodio reciente de negociaciones y disputas entre diferentes actores (activistas afroargentinos, agentes del estado local y agencias multilaterales de financiamiento por la inclusión de una cuantificación de la población afrodescendiente en Argentina en el próximo censo nacional 2010. Dicho fenómeno será comprendido en un marco de transnacionalización de los movimientos negros en la última década y de los impactos de la participación de países latinoamericanos en la Conferencia Mundial de las Naciones Unidas contra el Racismo, la Discriminación Racial, la Xenofobia y otras formas correlativas de Intolerancia, celebrada en Durban, Sud-África, en el año 2001. Examinamos cómo flujos y agentes globales revitalizan la discusión sobre las discontinuidades entre lo “étnico”, lo “racial” y lo “nacional”, reordenando nociones y clasificaciones de las minorías en el plano local, particularmente a través de los modos de contabilizar y categorizar a esas colectividades en las estadísticas oficiales.

    Full Text Available The Arroyo Malo Formation at Alumbre Creek, on the northern bank of the Atuel River, west central Argentina, comprises a c. 300 m thick continuous marine succession across the Triassic-Jurassic System boundary, consisting of massive and laminated pelites indicative of a slope depositional environment. Late Triassic invertebrates, including ammonoids, nautiloids, bivalves, gastropods, brachiopods and corals are restricted to the lower 150 m. Beds between 125-135 m from the bottom yield Choristoceras cf. marshi Hauer, a species found in the Marshi/Crickmayi Zone of Europe and North America, together with loose fragments of Psiloceras cf. pressum Hillebrandt, coeval with the lower to middle part of the Hettangian Planorbis Zone. About 80 m higher are beds yielding Psiloceras cf. rectocostatum Hillebrandt, a species that gives name to an Andean biozone partially coeval with the Johnstoni and Plicatulum Subzones, upper Planorbis Zone. Other fossils recorded in the Rhaetian strata of this section are foraminifers, ostracods and plant remains identified as Zuberia cf. zuberi (Szaj. Freng. and Clathropteris sp. The section was also sampled for conodonts and radiolarians, thus far with negative results. A palaeomagnetic study is underway.

  7. New evidence for an allochthonous plate in central southwestern Argentina?

    Rapalini, A. E.; Vilas, J. F.; Valencio, D. A.

    Preliminary paleomagnetic data for rocks from the Choiyoi Formation, exposed at the Cerro Chachil and Sierra de Catan-Lil (39.1°S, 70.5°W, Cordillera Principal, Argentina), assigned sensu lato to the Permo-Triassic, are discussed. The directions of the stable remanent magnetization (SRM) for these rocks have been submitted to the fold test. This analysis indicates that most of the Choiyoi Formation rocks are carriers of a prefolding SRM. The mean prefolding SRM for samples of normal and reversed polarity (within 40° of the mean; 277°, +54°, A95 = 8°, N = 21, K = 15.2, R = 19.683) yields a mean pole at 18°S, 126°W, 95 = 10°. The paleomagnetic data indicate two preliminary interpretations. One interpretation suggests that the sampling site rotated 90° clockwise around a vertical axis since Permian times. The other interpretation suggests that the sampling site integrates the allochthonous microplate suggested by Vilas and Valencio (1982) and Valencio and Vilas (1985). This microplate was situated in the Pacific at tropical latitudes in the late Paleozoic.

  8. Media cases and social memory in Argentina post 2001

    Full Text Available This paper seeks to define commotional media cases, to describe their structure and to provide a few examples, for the period following the economic and social crisis in Argentina in 2001. Specifically, the article aims to highlight some features of the production of these cases, which facilitate their penetration into social memory. Thus, some routines are used to record news output into memory. Repetition is a mark of the production process of these cases: cases pass from one medium to another and from one day to another, every medium repeats the background in every news story and associates news with other similar cases which generates “waves” with other news of the same type, and appeals to the archive for editing timelines to synchronize with the news. Journalists often use an earlier case as a model for the interpretation of a new case, hence, bringing it back to life. Sometimes these cases disseminate impacting images, which synthesize the content of the crisis they represent. Many cases serve a mythic function, to which politicians appeal for building their own government myths, thus nourishing collective memory. Frequently interest groups arise from these cases, which are very informed audiences affected by an issue and that appear in the public space to defend a cause. These audiences create slogans and specific forms of social protest, and actively use the media to disseminate their frame, adding their discourse of the case onto other discourses.

    Full Text Available Este artículo analiza un conjunto de consorcios tecnológicos apoyados con recursos públicos en Argentina, Chile, Colombia y Uruguay. Estos programas buscan facilitar la interacción entre empresas e instituciones dedicadas a la producción de ciencia y tecnología. Los resultados, basados en datos recabados para un subconjunto de los grupos apoyados, ponen en relieve las dificultades y los largos tiempos que se re-quieren para lograr resultados concretos, en particular, en innovación tecnológica. El trabajo cuantitativo muestra una evaluación relativamente baja de las empresas res-pecto al efecto de estos instrumentos en la generación de innovaciones de productos y procesos y la obtención de patentes, aunque existen aspectos relativamente mejor evaluados, como el mejoramiento del acceso a conocimiento tecnológico, en ámbitos como el mercadeo y los recursos humanos. Esto puede deberse a que varios de los consorcios llevan poco tiempo en funcionamiento y necesitan un plazo más largo para ser evaluados.

    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.

    Collaboration between Belgian experts and Argentina on the commissioning of Argentine reactors helped overcome problems caused by delays with construction. Marc Scibetta, deputy manager for nuclear materials science, from the Belgian Nuclear Research Centre (SCK CEN) gave an interview in which he told some facts to Lubomir Mitev of NucNet. The cooperation between SCK CEN an Argentina's Comision Nacional de Energia Atomica (CNEA) started in 2002. The first project was a support for the safety evaluation of the Atucha-1 reactor pressure vessel. When Argentina resumed the construction of Atucha-2 in 2006 - originally, construction started in 1981 but was suspended in 1985 due to financial reasons -, SCK CEN was asked to develop and implement a surveillance programme for the unit.

    We report the first finding of Echinococcus vogeli in a paca, Cuniculus paca, in the tropical forest of Misiones, in the north of Argentina. The presence of the bush dog, Speothos venaticus, E. vogelís only natural definitive host, was also reported. The polycystic hydatids, 2 to 3 cm in diameter, were only found in the liver of an adult paca. The size range of the hooks and the relative proportion blade/handle did not show significant differences with respect to the ones reported for E. vogeli. The size of E. granulosus hooks, measured for comparison purposes, was significantly smaller (p E. vogeli in Argentina. The probability of finding neotropical echinococcosis in humans reinforces the need to expand the search for E. vogeli in Argentina. Echinococcosis due to E. vogeli is very aggressive and may cause death in about a third of the human population affected.

    This article analyzes the development of the history of psychology in Argentina and Brazil, beginning with the emergence of the history of psychology at the beginning of the 20th century. The paper analyzes that such old historical reconstructions were written by the same authors or institutions that were introducing Psychology in the two countries. That is, the older historical productions in the field of psychology were Whig biased. An analysis of the last 30 years of history of psychology is also provided. The article describes institutional developments, including archives, journals, scientific meetings, and teaching of history of psychology in academic settings. Main groups devoted to history of psychology, both in Argentina and Brazil are described. Finally, it offers some thoughts on the future of history of psychology in the 2 countries. A comparative study between Argentina and Brazil allows to understand strengths and weakness related to institutionalization of History of Psychology. (PsycINFO Database Record
