    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.

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

    Argentina has embarked on an ambitious domestic nuclear research and energy program. The venture promises to provide the nation with the infrastructure to play an important role in the nuclear export market in the years ahead. Buenos Aires built its program on a foundation of international support and assistance that overlay an emerging sophisticated industrial and scientific establishment. The foreign contribution sensitized Argentina to opportunities in the global market. This paper reports that Argentina operates two heavy-water/natural uranium reactors, Atucha I and Embalse. Producing, respectively, 320 MW(e) and 600 MW(e), they supply roughly 10 percent of the country's electricity. With a capacity factor of 84 percent, Atucha I is among the best operated plants in the world. Plans call for a third, 745 MW(e) power plant, Atucha II, to go on line in the early 1990s. During this period, construction also may begin on three 300 MW(e) plants, although the country's foreign indebtedness plus cost overruns in earlier construction will place a heavy burden on these plans

    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

La principal hipótesis es que la TV digital abre una oportunidad única para reformar el actual modelo de radiodifusión basado en la concesión de un número reducido de licencias a operadores de tipo generalista. Al multiplicar la capacidad de transmisión y facilitar el desarrollo de servicios interactivos tanto de entretenimiento como educativos y de información, la transición a la TV digital se ofrece como instrumento de política pública para alcanzar objetivos clave en materia de comunicación, como el pluralismo, la apertura del mercado y el achicamiento de la llamada brecha digital.

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

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

  17. Argentina set for privatization

    International Nuclear Information System (INIS)

    Buyers are lining up for Argentina's two big state-controlled petrochemical groups, Buenos Aires-based Petroquimica General Mosconi (PGM) and Petroquimica Bahia Blance (PBB). However, feedstock supply contracts with government-owned oil group Yacientos Petroliferos Fiscales (YPG) and gas group Gas del Estado hold the key to both sales. Shell Compania Argentina Petroleo SA (CAPSA), Perez Companc, and Global Petroleum have already bought PGM tender documentation. Shell says it will bid for PGM if the feedstock contract with YPF is acceptable. In addition to price and volume, Shell says the length is critical; it wants a 15-year deal, but would settle for 11. YPF initially sought a five-year contract. PGM, which produces 300,000 m.t./year of aromatics, plus oxo alcohols, methanol, and methyl tert-butyl ether, has sales of $150 million/year

  18. Fruit fly eradication: Argentina

    Fruit exports account for 9% of Argentina's total agricultural exports and generate annually close to $450 million. This could be increased but for fruit flies that cause damage equivalent to 15% to 20% of present production value of fruit and also deny export access to countries imposing quarantine barriers. The Department of Technical Co-operation is sponsoring a programme, with technical support from the Joint FAO/IAEA Division, to eradicate the Mediterranean fruit fly using the Sterile Insect Technique (SIT).

    Argentina became highly "dollarized" during its hyperinflations of 1989 and early 1990. Although inflation has returned to very low rates, a high degree of dollarization has persisted during the early 1990s, counter to what the currency substitution hypothesis predicts. This paper provides new evidence that explains the continued dollarization of the Argentine economy. ; First, we develop a new measure of dollar currency circulating in foreign countries. This measure improves our ability to a...

  2. Argentina [Country report

    International Nuclear Information System (INIS)

    The airborne geophysical surveys developed in Argentina are described. They have got more than 500.000 km2 acquiring data for U, Th, K and total background activity. Other types of published data are also mentioned (satellite imagery, seismic hazard, climate, soil distributions, etc.). The availability of maps with the abundances of elements analyzed at the country and also at laboratories from Canada is described, as well as data of analysis of several elements at two study areas proposed at the outset of the project. The availability of process rate data and epidemiological data is also explained. Argentina intended fully to participate in the CRP at the outset of the project. Due, however, to external resource constraints imposed on the participating organization (Comision Nacional de Energia Atomica, CNEA), the level of participation had to be significantly reduced. Nonetheless, in the first period of the CRP, Argentina undertook to collate existing geological and geochemical information within the country, and began to define potential areas for site specific natural systems safety indicator studies.

  8. RERTR activities in Argentina

    International Nuclear Information System (INIS)

    The Atomic Energy Commission of Argentina has been an active participant of the RERTR program since 1978. An important milestone of the Argentinean RERTR program was the development and manufacturing at industrial scale of U3O8 dispersed fuel and its subsequent application to the conversion of the RA-3 reactor core to LEU fuel. More recently, our activities were focused on the development of U3Si2 fuel with a density of 4.8 gU/cm3 and the improvement of the manufacturing process of this type of fuel. The program to qualify CNEA as a supplier U3Si2 dispersed fuels is scheduled to finalize by mid 2003. To hasten this program the main research reactor of Argentina, the RA3, raised its power from 5 MW to 8 Mw in October this year. This is an intermediate step in the program to increase RA-3 power to 10 MW Currently, one of the main objectives is to develop and qualify the technology for the production of high-density LEU fuel elements using U-Mo alloy. An original way to produce U-Mo powder (the HMD process) was developed and its being upgraded to plant scale production. Another significant progress was the development of LEU targets for the production of 99Mo, in the form of miniplates prepared with dispersed LEU U-Alx. The shipment to USA of 207 MTR spent fuels containing US origin highly enriched uranium, successfully carried out in the end of 2000, is another remarkable achievement of the Argentinean RERTR program. This activity was carried out in the framework of the United States Foreign Research Reactor Spent Nuclear Fuel Acceptance Program. The fuels were fabricated in Argentina and used in the RA-3 reactor from 1968 to 1987. The inventory of the shipped HEU spent fuel consisted in 166 standard assemblies and 41 control assemblies.

    1994-01-01

    A significant increase in the number of isolations of Salmonella enteritidis has been observed in Argentina since 1986. Outbreaks of foodborne diseases in humans were associated with the consumption of raw or undercooked hens' eggs. Between 1986 and the first 6 months of 1993 there were 150 outbreaks reported, affecting more than 6000 persons. A total of 71.3% of these outbreaks were confirmed by stool cultures, and 47.3% by bacteriological study of the food implicated in the outbreak. A permanent surveillance of salmonellosis is imperative, taking into account the persistence of Salmonella enteritidis isolations in sporadic cases and in new outbreaks. PMID:8155472

  12. Activities with Argentina

    International Nuclear Information System (INIS)

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

    The Atomic Energy Commission of Argentina has been involved in the Reduced Enrichment for Research and Test Reactors Program since 1978. The most relevant milestones of the program, regarding fuel R and D activities, were the development and manufacturing at industrial scale of U3O8 dispersed fuel assemblies and the conversion of the RA-3 reactor core to LEU fuel. More recently, the activities were focused in the development of high density U3Si2 fuel with a density of 4.8 gU/cm3 and the improvement of the manufacturing process of U3Si2 powder. Currently one of the main objectives is to develop and qualify the technology for the production of high-density LEU fuel elements using U-Mo alloy. Several alternative ways to obtain U-Mo powder are under development with the aim of evaluating plant scale production and costs. To boost this program the main research reactor of Argentina, the RA-3, will be upgraded to 10 MW early in 2001 and the hot cells at the Ezeiza Atomic Center are fully operational after important investments. Significant progresses were also carried out in the development of LEU targets for the production of Mo99. Experimental work has demonstrated the feasibility of the manufacturing and radiochemical processing of miniplate targets prepared with dispersed UAlx, maintaining the geometry and the alkaline processing of the HEU targets used so far.

  16. Research reactors in Argentina

    International Nuclear Information System (INIS)

    Argentine Nuclear Development started in early fifties. In 1957, it was decided to built the first a research reactor. RA-1 reactor (120 kw, today licensed to work at 40 kW) started operation in January 1958. Originally RA-1 was an Argonaut (American design) reactor. In early sixties, the RA-1 core was changed. Fuel rods (20% enrichment) was introduced instead the old Argonaut core design. For that reason, a critical facility named RA-0 was built. After that, the RA-3 project started, to build a multipurpose 5 MW nuclear reactor MTR pool type, to produce radioisotopes and research. For that reason and to define the characteristics of the RA-3 core, another critical facility was built, RA-2. Initially RA-3 was a 90 % enriched fuel reactor, and started operation in 1967. When Atucha I NPP project started, a German design Power Reactor, a small homogeneous reactor was donated by the German Government to Argentina (1969). This was RA-4 reactor (20% enrichment, 1W). In 1982, RA-6 pool reactor achieved criticality. This is a 500 kW reactor with 90% enriched MTR fuel elements. In 1990, RA-3 started to operate fueled by 20% enriched fuel. In 1997, the RA-8 (multipurpose critical facility located at Pilcaniyeu) started to operate. RA-3 reactor is the most important CNEA reactor for Argentine Research Reactors development. It is the first in a succession of Argentine MTR reactors built by CNEA (and INVAP SE ) in Argentina and other countries: RA-6 (500 kW, Bariloche-Argentina), RP-10 (10MW, Peru), NUR (500 kW, Algeria), MPR (22 MW, Egypt). The experience of Argentinian industry permits to compete with foreign developed countries as supplier of research reactors. Today, CNEA has six research reactors whose activities have a range from education and promotion of nuclear activity, to radioisotope production. For more than forty years, Argentine Research Reactors are working. The experience of Argentine is important, and argentine firms are able to compete in the design and

  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.

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

  2. Argentina and Brazil

    International Nuclear Information System (INIS)

    This paper reports that security is defined in different ways by many international actors. To some, security is tied to the definition of an external threat to borders, as in the case of the NATO countries. To other, security is related to development, as in the case of most Third World countries. but notwithstanding different definitions, all countries recognize that the essence of security is the survival of the nation-state itself. The nuclear programs of Argentina and Brazil are among the oldest, most sophisticated and advanced nuclear programs anywhere in the Third World. The programs have never been explained on the basis of threat perception, and in this regard perhaps they constitute the most atypical form of nuclear proliferation known to date. Not surprisingly, any attempt to explain the rationale for the Brazilian and Argentine nuclear programs based on common issues of threat =merely confuses the issue. Thus, nationalism, the search for national identity and pride, the need to express self-sufficiency and the desire to keep options open in an insecure and evolving world order must all be analyzed to comprehend the likelihood of future types of nuclear proliferation. Meanwhile, the study of the contemporary era of Argentine-Brazilian nuclear rapprochement may provide new insights into the complex reasoning behind the decision of countries to go nuclear

Se realizó la estimación de la composición anatómica y taxonómica de los conjuntos; se examinaron diferentes aspectos tafonómicos y se evaluaron las modificaciones antrópicas. Los resultados indican que los taxones que habrían sido más explotados por estos grupos están representados principalmente por aquellos característicos de los ambientes fluviales de la zona. Entre ellos se destaca la presencia de especímenes correspondientes a distintas especies de peces, seguidos por mamíferos y roedores, entre los que es importante mencionar la presencia de Hydrochoerus hydrochaeris. Los trabajos de campo permitieron recuperar además del material faunístico, objeto de análisis en el presente trabajo, abundante cantidad de material cerámico, seguido por restos de carbón, material lítico, entre otros.

    Publicaciones recientes reflejan la preocupación de las autoridades antidopaje por el uso de sistemas simuladores de altitud y la posibilidad de considerarlos métodos dopantes. El objetivo de nuestro estudio fue el de comparar las modificaciones hematológicas inducidas por dos tratamientos con eritropoyetina recombinante humana (rHuEpo a diferentes dosis, frente a un protocolo de hipoxia normobárica intermitente (HNI en un modelo animal.
    Veinticuatro ratas Wistar macho jóvenes fueron divididas en 3 grupos experimentales: grupo sometido a HNI (12h pO2 12% /12h pO2 21% (n=8; grupo tratado con una dosis de 300 UI de rHuEpo (n=8 y grupo tratado con 500 UI de rHuEpo (n=8. Se extrajeron dos muestras de sangre a cada uno de los grupos experimentales (antes y después de los tratamientos. Nuestros resultados muestran incrementos muy similares, y estadísticamente significativos, en los valores de hemoglobina, de hematocrito y de reticulocitos, tanto en el grupo HNI como en el grupo tratado con 300 UI de rHuEpo tras los 15 días de tratamiento. El tratamiento con 500 UI de rHuEpo produjo un incremento significativamente mayor.
    La principal conclusión de nuestro estudio es que las modificaciones de los parámetros hematológicos obtenidas mediante un protocolo de HNI son similares a las obtenidas con un tratamiento con 300 UI de rHuEpo.

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

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

  11. Nuclear energy regulation in Argentina

    International Nuclear Information System (INIS)

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

  12. Argentina and Brazil: an evolving nuclear relationship

    International Nuclear Information System (INIS)

    Argentina and Brazil have Latin America's most advanced nuclear research and power programs. Both nations reject the Non-Proliferation Treaty (NPT), and have not formally embraced the Tlatelolco Treaty creating a regional nuclear-weapon-free zone. Disturbing ambiguities persist regarding certain indigenous nuclear facilities and growing nuclear submarine and missile capabilities. For these, and other reasons, the two nations are widely considered potential nuclear weapon states. However both nations have been active supporters of the International Atomic Energy Agency (IAEA) and have, in recent years, assumed a generally responsible position in regard to their own nuclear export activities (requiring IAEA safeguards). Most important, however, has been the advent of bilateral nuclear cooperation. This paper considers the evolving nuclear relationship in the context of recent and dramatic political change in Argentina and Brazil. It discusses current political and nuclear developments and the prospects for maintaining and expanding present bilateral cooperation into an effective non-proliferation arrangement. (author)

  13. Spent fuel management of NPPs in Argentina

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    With the purpose of studying the radioactive fallout present in Argentina from atmospheric nuclear explosions tests that have been conducted recently, an environmental monitoring program, outside the influence of nuclear facilities of Argentina, was undertaken during 1996 and 1997. The levels of Cs-137 and Sr-90 were analysed in samples of air, deposited material (rainwater), milk, an average meal of a standard man and food. During this period, a total of 630 radiochemical analysis were performed on 325 samples of the different matrices described. The concentration levels of the radionuclides analysed in the different environmental matrices are presented and are compared with the values obtained in the environmental monitoring program done during the period 1960-1981.

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

  5. Argentina: Nuclear power development and Atucha 2

    International Nuclear Information System (INIS)

    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.

  6. Licensing new uranium production projects in Argentina

    International Nuclear Information System (INIS)

    Due to the decision to complete construction and begin operation of the Atucha II Plant, Argentina's nuclear reactor fuel requirements will increase in the mid-term from 120 tU/year to 220 tU/year. Current market conditions justify reactivation of indigenous production of uranium concentrates that could progressively replace imports. Consequently, CNEA presented to the Mendoza Province and national (Nuclear Regulatory Authority) licensing authorities a proposal for reactivation of the San Rafael Mining-Milling Complex. The main step in the licensing process is the Environmental Impact Assessment (EIA). This includes both assessment of the engineering for remediation of waste generated during previous production activities, and of environmental management of future production activities. The EIA was carried out by the National Technological University. The Cerro Solo Project, Chubut Province, which is currently at the pre-feasibility stage, is being considered for initiation of the feasibility study and development-production stage. Under present market conditions, the estimated project production cost has become competitive, and the resources of the project could be sufficient to supply the long-term needs of Argentina's nuclear power plants. Taking into account the increasing interest in environmental issues, and stricter environmental regulations, the main challenges to re-activation of uranium production in Argentina are: improvement of interaction with local communities; training of skilled personnel in waste management; and developing cost estimates and plans for mine-mill closure.

    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

    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.

    Full Text Available This article summarizes the background of empirical journalism studies in Argentina.  In recent publications, researchers have consistently underscored the lack of data on the profession and the scarce development of theoretical frameworks related to journalism studies.  The local investigations have prioritized approaches and methods that do not give the whole picture of the population of journalists. Most of the research tends to equate media analysis and media messages with journalism study and keeps on failing to provide data that allows for learning about the working conditions and the professional profile of the Argentinean journalists.

  4. Central Argentina de Elementos Modulares (CAREM)

    International Nuclear Information System (INIS)

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

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

  6. The industrial nuclear fuel cycle in Argentina

    International Nuclear Information System (INIS)

    The nuclear power program of Argentina for the period 1976-85 is described, as a basis to indicate fuel requirements and the consequent implementation of a national fuel cycle industry. Fuel cycle activities in Argentina were initiated as soon as 1951-2 in the prospection and mining activities through the country. Following this step, yellow-cake production was initiated in plants of limited capacity. National production of uranium concentrate has met requirements up to the present time, and will continue to do so until the Sierra Pintada Industrial Complex starts operation in 1979. Presently, there is a gap in local production of uranium dioxide and fuel elements for the Atucha power station, which are produced abroad using Argentine uranium concentrate. With its background, the argentine program for the installation of nuclear fuel cycle industries is described, and the techno-economical implications considered. Individual projects are reviewed, as well as the present and planned infrastructure needed to support the industrial effort

    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.

  8. Spent Fuel Management of NPPs in Argentina

    International Nuclear Information System (INIS)

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

    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 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

    Nuclear activity started in Argentina in the early fifties and since then all the peaceful applications of nuclear energy have been developed including nucleo electricity production. In 1994 the organization in charge of the regulatory control of nuclear activities, now the Nuclear Regulatory Authority (ARN), became independent from the organizations related with nuclear promotion (mainly National Atomic Energy Commission, CNEA). Concerning regulatory activities, the regulatory system applied by ARN in Argentina is based on the IAEA's and ICRP's recommendations, adapted to the needs of the country and its own experience gained through more than thirty years of regulatory activities. Besides, specialists from the regulatory organization from Argentina contributed to the development of the recommendations of such organizations. In order to contribute to the understanding of the application of the nuclear regulatory system in Argentina, an overview of the legal and regulatory framework is provided. (author)

  3. Radioactive waste with 14C in Argentina

    International Nuclear Information System (INIS)

    14C is a long half-life radioisotope, which is present in radioactive waste generated during the operation and decommissioning of nuclear power plants. 14C can also be found in waste generated by medical diagnostic laboratories or any one generated by fields that deal with research and development (mainly connected with the biochemists area). According to international precedents the disposal of 14C based on the final amount found in radioactive waste and its chemical form have conditioned the design and operation of the facilities (either because of the amount of it or the chemical form in which 14C was present). We have to take into account that the design of facilities for radioactive waste disposal is included among the obligations of the National Radioactive Waste Management Program (PNGRR). It is absolutely necessary to count with enough information about the characteristics of any waste containing 14C that is generated in Argentina, in order to be able to fulfil the requirements previously mentioned. The main characteristics of interest in the frame of the present project are: a) the principal reactions that take place for the formation of 14C; b) The specific concentration of activity in materials where this radio nuclei is formed or is accumulated; c) To know which is the current step in the process of managing these wastes (in Argentina and all over the world). Either if it refers to bulk or conditioned storage, inside the generating facility; d) Transportation possibilities of 14C under these conditions; e) The accumulated volume and the generation rate of this kind of waste in Argentina. This paper presents an initial collection and evaluation of the information related to the characteristics already mentioned, having gathered published material from the literature and information in the PNGRR up to this moment.

  4. Argentina's regulatory body: its communication activities

    International Nuclear Information System (INIS)

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

    The aim of this paper is to disentangle the different forces shaping Argentine immigration policy from 1870 to 1930. Although immigration restrictions increased over time Argentina remained relatively open to mass migration until the 1930s in contrast with the United States. The quantitative evidence presented here suggests that there were economic reasons to restrict immigration prior to the 1930s, namely rising inequality and a declining demand for workers. Labour in Argentina would have be...

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

    International Nuclear Information System (INIS)

    The Argentine Nuclear Power Plants (NPP) ATUCHA I (357 Mw, SIEMENS) and EMBALSE (648 Mw, CANDU), both of PHWR type, were owned and operated until August 94 by the Comision Nacional de Energia Atomica (CNEA). Until that date, CNEA, the national agency for nuclear R and D, concentrated three activities or roles: Research, Nuclear Regulations and NPP Operation. Since August 1994 NPP's are owned and operated by a state electrical company (Nucleoelectrica Argentina S.A.) the nuclear utility supplying 15% of the national electrical generation demand. NASA is going to be privatized according to a recent national law regulating nuclear activities. The transition from a research agency to a commercial company requires the introduction of changes in the management of activities. Mention of these changes is limited to those relating to Safety

    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.

  19. 222Rn Measurements in Dwellings of Argentina

    International Nuclear Information System (INIS)

    Radon gas (222Rn) is responsible of about fifty per cent of the world population dose due to natural sources, being the most important pathway the inhalation of radon progeny, specially indoors. Radon concentration has been measured in dwellings at different locations in Argentina. The places selected to be evaluated are representative of the different geologic zones of the country. Near 3000 dwellings have been analyzed since 1983 up today. The measuring methods used in this case were track etched detectors, electrets and detectors based on activated charcoal adsorption. Two different methods with track etched detectors were used: a simple one, which determines only the average radon concentration, and a second one that measures both radon concentration and the equilibrium factor (F) between radon and its daughters. The last one is a method that uses two Makrofol passive track detectors in the same device. The average radon concentration value obtained from all the dwellings evaluated was 44.2 Bq.m-3. The annual effective dose calculated from this average concentration, using a dosimetric factor of 25 μSv.a-1.(Bq.m-3)-1, which assumes an equilibrium factor of 0.4, was 1.11 mSv. The average value obtained from the 222 dwellings evaluated by the second method was 49.3 Bq.m-3 and 0,37 the equilibrium factor, resulting the annual effective dose estimated 1,44 mSv. The measured equilibrium factor of 0,37 allows us to verify the assumed equilibrium factor of 0,4. Finally, radon levels in dwellings of Argentina are within the acceptable values for population, not being necessary to implement remedial actions, except in isolate cases that are still under study.

    Full Text Available Post-translational modifications of proteins control many biological processes. This is also important process in virus including hepatitis B. However, there is no in-depth study on the whole hepatitis B virus large envelope protein. In this work, potential protein post-translational modifications in hepatitis B virus large envelope protein were determined by a standard bioinformatics technique. Furthermore, potential single amino acid substitutions in hepatitis B large envelope protein were also determined. It can be seen that there are possible 3 potential protein were post-translational modifications with 1 possible single substitution. This data can be useful for further study on hepatitis B virus mutant as well as planning for new vaccine production.Las modificaciones postranslacionales que sufren las proteínas controlan muchos procesos biológicos. Esto es también válido en el caso de los virus, incluyendo el de la hepatitis B. Sin embargo, no se han realizado estudios en profundidad de la totalidad de la proteína grande de superficie del virus de la hepatitis B. En el presente estudio, se han determinado las modificaciones postranslacionales que son posibles en esta proteína de la cubierta viral empleando para ello una técnica bioinformática estándar. Además, también se determinaron las sustituciones de un solo aminoácido que son posibles en la proteína grande de la superficie del virus de la hepatitis B. De este análisis podemos deducir que existen 3 posibles modificaciones translacionales en esta proteína y una potencial sustitución simple. Estos datos pueden ser útiles tanto para posteriores estudios sobre el virus mutante de la hepatitis B, como para la producción de una nueva vacuna contra este virus.

    2008-03-01

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

  9. Economy-wide impacts of biofuels in Argentina

    International Nuclear Information System (INIS)

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

  10. Market brief : the natural gas vehicle market in Argentina

    International Nuclear Information System (INIS)

    This report presents an overview of the natural gas vehicle (NGV) market in Argentina and describes the potential for Canadian suppliers to enter into joint ventures to establish local production facilities and transfer technology expertise. Argentina has the most developed NGV market in the world, with more than 1.3 million vehicles running on compressed natural gas (CNG). This number is expected to reach 2 million by 2010, for an overall market share of 25 per cent of all vehicles in Argentina. The NGV conversion and service station equipment market was valued at about $650 million in 2003. The strong domestic industry for Argentina's NGV market is the gateway to Brazil, Columbia, Mexico and Venezuela. The main regulatory body for the distribution of natural gas and the use of natural gas vehicles and equipment is ENARGAS. Canadian products must conform to ENARGAS regulations and codes. Opportunities exist for new cost-effective technologies that improve the safety and efficiency of converted vehicles. This report describes the key factors shaping market growth with particular reference to sector reform, and opportunities with actual and planned projects. The competitive environment was also discussed with reference to local capabilities, international competition, Canadian position, and a competitive advantage through Canadian government policies and initiatives. A section of the report on public-sector customers described the several organizations that manage and approve natural gas vehicle projects. Considerations for market-entry in Argentina were also outlined

    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.

  15. Argentina's chemical makers seek government support

    International Nuclear Information System (INIS)

    Argentina's chemical industry association, Camara de la Industria Quimica y Petroquimica (CIQYP; Buenos Aires), has started negotiations with the government aiming to stem industry-wide losses, which reached $236 million during the past 18 months. CIQYP blames the poor performance on worldwide over-supply and falling prices, which have curbed exports, and low tariffs, which have spurred imports. It is calling for higher import tariffs and export incentives. The talks will also focus on a possible bond issue that would support companies willing to restructure and modernize operations. The main factor hindering competitiveness is what CIQYP president Alejandro Achaval calls Argentinean cost, including high energy costs, high provincial and federal taxes, and high financing charges. Since 1988, the industry has cut prices by 30%, formed mergers and joint ventures, closed 11 plants and started five new ones, slashed the workforce by 27%, and engaged in the government's privatization program. Meanwhile, plans to privatize 64% of aromatics producer Petroquimica General Mosconi(PGM) were derailed when potential bidders Diamond Shamrock, Shell, and Perez Companc refused for the second time to make offers on February 2.

  16. Deep geological disposal research in Argentina

    International Nuclear Information System (INIS)

    Argentina shall require a deep geological repository for the final disposal of radioactive wastes, mainly high-level waste (HLW) and spent nuclear fuel produced at two nuclear power plants and two research reactors. In the period 1980-1990 the first part of feasibility studies and a basic engineering project for a radioactive high level waste repository were performed. From the geological point of view it was based on the study of granitic rocks. The area of Sierra del Medio, Province of Chubut, was selected to carry out detailed geological, geophysical and hydrogeological studies. Nevertheless, by the end of the eighties the project was socially rejected and CNEA decided to stop it at the beginning of the nineties. That decision was strongly linked with the little attention paid to social communication issues. Government authorities were under a strong pressure from social groups which demanded the interruption of the project, due to lack of information and the fear it generated. The lesson learned was: social communication activities shall be carried out very carefully in order to advance in the final disposal of HLW at deep geological repositories (author)

  17. Overview in Argentina on radioactive waste management

    International Nuclear Information System (INIS)

    The National Atomic Energy Commission (CNEA) of the Argentina Republic was established in 1950. It has in operation two nuclear power plants; a third one is under construction (70% completed) and a fourth one is under study. In order to supply the fuel elements to the nuclear power plants mentioned before, CNEA has implemented the front part of the Fuel Cycle. Regarding the back-end, the actual policy concerning to the spent fuel elements, is to storage them waiting for further decision. Together with these activities, the CNEA has developed, in practice, all the peaceful applications of nuclear energy. Mentioned activities, generate important volumes of radioactive wastes of different characteristics and the overall strategy of the Argentine Program is to plan, develop and implement the technology and provide the facilities for the permanent isolation of the generated wastes, with the aim that not compromise the health and safety of general public. To implement and coordinate all these activities CNEA has established a Radioactive Waste Management Program. In this paper an outline is given concerning the policy, treatment, conditioning, characterization, storage, transport and final disposal of radioactive wastes in our country. (author)

The Northwest Basin comprises the following four successor basins that are different in characteristics and tectonic development: pre-Carboniferous, Carboniferous, Cretaceous, and Tertiary basins. Petroleum plays in the Northwest Basin can be divided into four types based on hydrocarbon-trap structures. These include thrust-folds, paleo-channels, volcanic mounds and roll-over anticlines related to normal faulting. The thrust-fold structure is a typical trap structure of pre-Carboniferous and Carboniferous basins, and consists of Cretaceous sedimentary rocks in southern exploration areas of the Northwest Basin. Paleo-channels provide a new possibility to the Carboniferous basin, and several of them occur in northern exploration areas of the Northwest Basin. Volcanic mounds and roll-over anticlines associated with the normal fault are related to the rifting event and play an important role in the Cretaceous basin. New prospects will be found if the above play types are well utilized. (author). 12 refs., 15 figs.

  19. National uranium development programme in Argentina

    International Nuclear Information System (INIS)

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

  20. Medical response to radiation emergencies in Argentina

    International Nuclear Information System (INIS)

    Although radiation accidents are not frequent, the increasing use of radioisotopes in medicine and industry increases the likelihood of such accidental situations. Additionally, risks posed by the malevolent use of radiation sources have been highlighted during the last few years. In this context, the enhancement of national capabilities for medical assistance of victims in radiation emergencies becomes relevant. This communication describes the organization of medical response to radiation emergencies existing in Argentina. A three-level system for medical response has been developed: pre-hospital response given on-site by local emergency services, assistance provided by emergency departments of local general hospitals and central reference hospitals for treatment of acute radiation syndrome, cutaneous radiation syndrome and internal contamination. An education and training program is regularly executed at the three levels, including theoretical background as well as practical training. Guidelines and protocols for medical handling of victims have been elaborated and implemented. Research and development of new strategies for diagnosis and treatment of radiation injuries are promoted by ARN in close collaboration with physicians belonging to reference hospitals. (author)

  1. Strategy for waste management in Argentina

    International Nuclear Information System (INIS)

    The National Atomic Energy Commission (CNEA) of the Argentina Republic was established in 1950. It has in operation two nuclear power plants; a third one is under construction (70% completed) and a fourth one is under study. In order to supply the fuel elements to the nuclear power plants mentioned before, CNEA has implemented the front part of the Fuel Cycle. Regarding the back end, the actual policy concerning to the spent fuel elements, is to storage them waiting further decision. Together with this activities, the CNEA has development, in practice, all the peaceful applications of nuclear energy. Mentioned activities, generated important volumes of radioactive wastes of different characteristics and the overall strategy of the Argentine Program is to plan, develop and implement the technology and provide the facilities for the permanent isolation of the generated wastes, with the aim that not compromise the health and safety of general public. To implement and coordinate all these activities CNEA has established a Radioactive Management Program. In this paper an outline is given concerning the policy, treatment, characterization, storage, transport and final disposal of radioactive wastes in our country. (author)

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

    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.

  6. The regulatory control of radioactive sources in Argentina

    International Nuclear Information System (INIS)

    Argentina has been conducting nuclear activities for more than forty years, and had established a Regulatory Authority as early as in 1956. Procedures for compliance monitoring and enforcement have been in use in the regulatory control of radioactive sources, and regulatory standards and regulations were in force in Argentina before the accident in Goiania. The conclusions drawn from the Goiania accident encouraged the Argentine authorities to improve some regulatory procedures and helped to enhance the quality of the regulatory process. As a result, the effectiveness of the control of spent radioactive sources has gradually increased, and enforcement actions to prevent radioactive sources ending up in the public domain have improved. Lessons learned in Argentina from the accident in Goiania are presented as well as the main characteristics of an effective enforcement programme to prevent radiological accidents when radioactive sources are used for industrial, medical, research and teaching purposes.

    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.

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

    International Nuclear Information System (INIS)

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

    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)

  4. MOX fuel development: Experience in Argentina

    International Nuclear Information System (INIS)

    Since 1973, when a laboratory conceived for the safe manipulation of a few hundred grams of plutonium was built, the CNEA (Argentinean Atomic Energy Commission) has been involved in the small-scale development of MOX fuel technology. The plutonium laboratory consists in a glove box facility (α Facility) featuring the necessary equipment to prepare MOX fuel rods for experimental irradiations and to carry out studies on preparative processes development and chemical and physical characterization. The irradiation of the first prototypes of (U,Pu)O2 fuels fabricated in Argentina began in 1986. These experiments were carried out in the HFR (High Flux Reactor)- Petten , Holland. The rods were prepared and controlled in the CNEA's a Facility. The post-irradiation examinations (PIE) were performed in the KFK (Kernforschungszentrum Karlsruhe), Germany and the JRC (Joint Research Center), Petten. In the period 1991-1995, the development of new laboratory methods of co-conversion of uranium and plutonium were carried out: reverse strike co-precipitation of ADU-Pu(OH)4 and direct denitration using microwaves. The reverse strike process produced pellets with a high sintered density, excellent micro-homogeneity and good solubility in nitric acid. Liquid wastes showed a very low content of actinides and the process is easy to operate in a glove box environment. The microwave direct denitration was optimized with uranium alone and the conditions to obtain high density pellets, with a good microstructure, without using a milling step, have been developed. At present, new experiments are being carried out to improve the reverse strike co-precipitation process and direct microwave denitration. A new glove box is being installed at the plutonium laboratory, this glove box has process equipment designed to recover scrap from previous fabrication campaigns, and to co-convert mixed U-Pu solutions by direct microwave denitration.

    International Nuclear Information System (INIS)

    Some spices produced in Argentina ground red pepper, anise, fennel, laurel, paprika, Cayenne pepper, cumin (seed), and mayoram (leaves and flowers), were irradiated to inactivate microbial lead, without causing significant chemical or sensory alterations. They were packed in polyethylene bags of 100 m thickness, and irradiated at the 60Co semi-industrial facility of the Ezeiza Atomic Center, with doses of 7 and 10 kGy, and dose rate of 93.87 Gy/min. Dosimetric data were evaluated with potassium nitrate. Control and irradiated samples were stored at room temperature. Chemical analysis were performed to verify the Argentine Alimentary Codex specifications: water content; essence; total ash; ash insoluble in acid; alcoholic, volatile ether and non-volatile ether extracts; starch; and crude fiber. Besides, colour and volatile substances were analyzed. No differences were found between control and irradiated samples, with the exception of an increase in the total amount of volatiles released by irradiated spices, and a slight colour loss in mayoram. Microbiological determinations consisted of aerobic plate count, yeasts and moulds, coliform bacteria, Salmonella, Staphylococcus aureus, mesophilic and thermophilic sporeformers, enterococci and Clostridium perfringens. Microbial load in control samples oscillated between 103 and 106 microorganisms per gram, and was inhibited with 10 kGy to undetectable level. With 7 kGy, survivors were still detected in: cumin, anise, laurel, red pepper, fennel and paprika. So, the purpose of this work was accomplished with the dose of 10 kGy. Great improvement on the quality of those products which being stored at room temperature are consumed in the raw state, would be attained. (Author)

    2011-02-01

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

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

Para ello se realiza un estudio epidemiológico descriptivo de la tendencia temporal, a través de las siguientes variables: sexo, grupos de edad, intencionalidad y jurisdicción. Los datos fueron obtenidos en la Dirección de Estadísticas e Información en Salud del Ministerio de Salud de la Nación. Se encontraron 87.671 muertes por armas de fuego. Los varones representaron el 85,7% y su tasa más alta fue para el año 2002 con 21,2 muertes por 100.000 habitantes. El grupo de edad que concentró la mayor cantidad de muertes por armas de fuego fue el de 20 a 29 años (25,6%. Las tasas ajustadas más altas corresponden a los años 2000-2002 con valores entre 10,0 y 11,6 muertes por cada 100.000 habitantes, período que coincide con la crisis económicoinstitucional que atravesó el país. La provincia de Buenos Aires fue el lugar de residencia del 49,1% de las muertes. En la discusión se abordan dimensiones político-económicas e ideológico-culturales en la relación entre armas, violencias, ciencia y sociedad.

    Full Text Available Con el objetivo de analizar la mortalidad por armas de fuego en Brasil y Argentina entre 1990 y 2005, se realizó un estudio epidemiológico descriptivo utilizando datos oficiales de mortalidad de ambos países. Se analizaron número, proporción y tasas crudas y ajustadas para cada tipo de muerte (catalogadas según la CIE-9a y CIE-10a, el total por año y el promedio anual del período, sexo y edad. Los perfiles globales de los dos países presentaron tendencia creciente, pero Brasil mostró valores superiores de muertes y homicidios por armas de fuego en todo el período. A partir de los resultados se discute la hipótesis: el perfil de Brasil, particularmente el de homicidios por armas de fuego, es consecuencia no solo de la violencia social que responde a la persistentemente alta desigualdad y exclusión en que vive gran parte de la población, sino también al surgimiento, expansión y fortalecimiento de diversos grupos armados en ese país. El perfil argentino resultaría en parte del aumento de la violencia social también como respuesta al deterioro socioeconómico imperante, y por otra parte, sería consecuencia de la histórica monopolización de la violencia por parte del Estado

  10. Wind energy. A challenge for Argentina

    Energy Technology Data Exchange (ETDEWEB)

    Spinadel, Erico [Argentine Wind Energy Association, Florida (Argentina)

    2009-07-01

    It is widely known that the Argentinean Republic counts on with a strong wind resource. Mainly, according with the most spread idea, in the Patagonic region. Certainly, at the south of the 40-degree southern parallel, there is a wind corridor blowing from west to east, which is no comparable to any other, at least on continental areas. The southern province of Chubut, as well as the northern region of the province of Santa Cruz have regular and constant winds reaching average speeds higher than 11 m/s, permanently blowing in a E to ESE direction. So, turbine use factors higher than 35% are easily achievable. Those are ideal conditions for the harvesting of wind energy, that are however constrained by the long distances between that region and the main consumption centers, as well as by the lack of adequate high-voltage transmission lines that, at this moment, are still on a preliminary building stage. The drawbacks derived from the long transportation distances are increased by the fact that the Argentinean high-voltage grid are of 500 kV AC, featuring higher losses than those of 700 kV (or even 1.000kV) normally used in Europe. To this inconveniences also linked the lack of an adequate legislation, able to encourage possible investments. Fortunately, there are also in Argentina other regions featuring winds with average values between 7 m/s and 10 m/s, both along the Atlantic seashore of the Buenos Aires Province, and in some of the centrally-located provinces. Those areas are indeed supplied by the high voltage grid, and present also an important electricity demand. Regrettably, those grids have a radial configuration, and relatively few interconnections, having therefore few connecting nodes for entering the production of the eventual wind farms, thus requiring the building of long additional high-voltage lines.

  14. Summary of CRP participants' reports: Argentina

    International Nuclear Information System (INIS)

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

  15. Uranium favourability and exploration in Argentina

    International Nuclear Information System (INIS)

    Full text: This paper presents an overview of the past and ongoing uranium favourability and exploration activities in Argentina, where different metallogenetic models are analysed and the radiometric surveys have a prominent place as a prospecting technique. Uranium exploration activities in Argentina began in 1951-1952. The Huemul sandstone type uranium deposit was found in 1954, while exploring for red bed copper mineralisation. The Tonco district with the sandstone deposits Don Otto and Los Berthos was discovered by an airborne radiometric survey conducted in 1958. During the late 1950s and the early 1960s, airborne surveys also led to the discovery of the Los Adobes sandstone type uranium deposit in Patagonia. During the 1960s, the Schlagintweit stockwork deposit and La Estela vein deposit were found by ground exploration in the granitic basement of the Pampean Ranges. In 1968, an airborne survey led to discovery of the Dr. Baulies deposit, which occurs in volcanoclastic sediments, in the Sierra Pintada district in Mendoza Province. During the 1970s, another extensive airborne survey contributed to the discovery of Cerro Condor U deposit. Considering the geological and structural evidence, a drilling program was executed in the vicinity of the Los Adobes deposit, finding U mineralization at the Cerro Solo location. An airborne gamma ray spectrometry survey carried out in 1978, covering 100,000 square kilometres of the Patagonia Region, contributed to the discovery of the small Laguna Colorada deposit located in a volcanic environment. Furthermore, this airborne survey defined several clusters of uranium anomalies that were investigated in detail. During the 1980s, an airborne survey conducted over 40,000 square kilometres of the granitic terrain of the Pampean Ranges, identified a number of strong uranium anomalies that became exploration targets. In 1986, ground exploration identified the uranium vein type mineralization at Las Termas in the Fiambala Ranges

    2011-12-01

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

  15. Regulatory control of research reactors and critical assemblies in Argentina

    International Nuclear Information System (INIS)

    Full text: The Nuclear Regulatory Authority (ARN) was established as an autonomous body reporting to the President of Argentina by Act 24,804 known as the Nuclear Activity National Act, which came into force on April 25, 1997, and is empowered to regulate and control the nuclear activity with regard to radiation and nuclear safety, physical protection and nuclear non-proliferation issues. It must also advise the Executive on issues under its purview. The objective of the Nuclear Regulatory Authority is to establish, develop and enforce a regulatory system applicable to all nuclear activities carried out in Argentina. The goals of this regulatory system are: To provide an appropriate standard of protection for individuals against the harmful effects of ionizing radiation; To maintain a reasonable degree of radiological and nuclear safety in the nuclear activities performed in Argentina; To ensure that nuclear activities are not developed with purposes un-authorized by the law and regulations resulting therefrom, as well as by the international agreements and the nonproliferation policies adopted by Argentina; To prevent the commission of intentional actions which may either have severe radiological consequences or lead to the unauthorized removal of nuclear materials or other materials or equipment subject to control. In the field of Radiological and Nuclear Safety control applied to Research Reactors and Critical Assemblies, ARN's regulatory activities are directed at controlling 3 RR and 3 CA, analyzing design and operation-related documents, permanently assessing safety during operation, and verifying by means of regulatory inspections and audits the compliance with the provisions of the license concerned. This paper describes the regulatory control applied to Research Reactors and Critical Assemblies in Argentina, the criteria, the standards, the annual plan, the subjects and interaction with operators and operating organization.

  17. Small mammal distributional patterns in Northwestern Argentina

    María L. Sandoval

    2015-12-01

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

  18. Radionuclide Activity Concentrations in Spas of Argentina

    International Nuclear Information System (INIS)

    Geothermal waters have been used on a large scale for bathing, drinking and medical purposes. These waters often have a very high mineral content because solubility increases with temperature. Ground waters are in close contact with soil and rocks containing radium. Once formed by decay from radium, radon gas (Rn-222) may diffuse through rocks pores and geological discontinuities and may dissolve in these waters. Radon and other natural radionuclides are transported to the surface where radon can easily diffuse into the atmosphere. Then it may be possible to find out significant radon levels at places like geothermal spas. In this work the most important natural radionuclide activity concentrations in different thermal spas of Argentina were measured to characterize waters and to evaluate the exposure of workers and members of the public. Three passive methods were used to measure radon in air. One of them is an screening method based on the radon adsorption on activated charcoal. The other two methods are time integrated ones, CR-39 or Makrofol tracks detectors, which can be exposed between two and three months. To characterize waters other natural radionuclides have been also measured. Uranium concentration was measured by fluorimetry. Ra-226 and Pb-210 measurements were performed by radiochemical methods and liquid scintillation. The results obtained were compared with the guidelines values recommended by WHO and EPA for drinking waters and, in the case of radon in air, the results were compared with values established by BSS-115. In order to assess worker doses, the higher value measured for radon in air and real scenario data were taken into account. Moreover, in situ dose rate measurements were also performed and then compared with natural background values. In relation with water characterization, almost all values obtained for the geothermal waters analyzed were below the corresponding guidance levels. Taking into account the highest value measured of radon

  10. Emergency action plan in the Comahue region, Argentina

    International Nuclear Information System (INIS)

    The first Emergency Action Plan (EAP) developed in Argentina for the major hydro basins in the country was described. The guidelines for the EAP came from the United States, but the criteria were adapted to the characteristics of the hydro projects and the rivers under study. The plan allowed, with an adequate degree of precision, the determination of the permissible levels that the rivers could reach, all along the region under study, in case an emergency was detected in one of the dams. It was possible to elaborate the flood maps at two different scales which, in turn, allowed visualization of the scope of each emergency. The plan was said to represent a major landmark in flood control in Argentina, and will serve as the basis of all future emergency planning. 11 ills

    Updated data for the spent fuel management from the operating power reactors - as of December 31st, 2004 - as well as research reactors - as of March 1st, 2003 - in Argentina are presented. Data for the power reactor spent fuel are received from the nuclear power plant operator (Nucleoelectrica Argentina S.A.) twice a year for the cumulative spent fuel arising up to June 30th and December 31st. Data for the research reactor spent fuel are collected once a year from CNEA operators. At the time being, such data are not managed in a database management system but some of them are handled with a spreadsheet program in order to get total, average, lower and higher values. These values are being used to built the input of codes for calculating the composition, activity and thermal power for the spent fuel as a whole as well as the mass, activity and thermal power for spent fuel elements or nuclides.

  13. Industrial integration of the fuel cycle in Argentina

    International Nuclear Information System (INIS)

    The power-reactor construction program in Argentina for the period 1976-1985 is described on the basis of which the nuclear-fuel requirements have been determined. Activities connected with the fuel cycle commenced in 1950 in Argentina with the prospection and working of uranium deposits. On the basis of the nuclear power program described, plans have been drawn up for the establishment of the industrial plants that will be needed to ensure the domestic supply of fuel. The demand for fuel is correlated with the availability of uranium resoures and it is shown to be desirable from the technical, economic and industrial point of view to integrate the front end of the fuel cycle, keeping the irradiation aspects and the tail end at the development level. Progress made in this field and current programs covering exploration, concentrate production, nuclear purification, conversion to uranium dioxide, production of special alloys and fuel element fabrication are described

Se revisan las alternativas de desarrollo de las presidencias de Duhalde y Kirchner respecto a la de Menem, a través de la literatura publicada sobre Argentina durante ese periodo. 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.

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.

    AIM: To estimate the progression of the hepatitis C virus (HCV) epidemic and measure the burden of HCV-related 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 liver-related 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.

    Full Text Available This paper reflects outcomes of research comprising an area or type of education in a way unknown and generating interest today: classrooms and hospital schools. The study of this educational track in Argentina is limited to the specific context of child hospitals. Even though the aim is not idealizing Hospital Education model through the sequence of ideas contained, note that the historical example of survival and development offered by the Argentinian context can lead many contributions and suggestions for improvement in other national contexts that make up this educational track. Therefore, constituting Argentina one of most advanced countries in some dimensions related to educational care in hospitals, we have to present its prism of experience with an emphasis on purposes such as compensating, egalitarian fact and social risk minimization that this educational service for hospitalized children implies.Received: 30/04/2013 / Accepted: 22/09/2013How to reference this articleGarcía Álvarez, A.

    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

    Full Text Available The 200 year anniversary of the foundation of Argentina and the 150th anniversary of Italian unification marks the occasion for an historical analysis of the presence of Italians in Argentina. The article examines the topic from the 1930s until post WW2, comparing immigration in Argentina with other nations including Australia and the US. The position of immigrants in Argentinian social structure is analysed, individualising 3 elements: that foreigners made up 30% of the population; that there was a high concentration of immigrants living in urban areas, and that in big cities foreigners made up 2/3 of the middle and working classes. Secondly, the influence of Italian immigrants on Argentinian politics is examined, in particular the influence on the Partido Socialista and the Partido Radical, and the role of Italians in protest movements and Argentinian civil wars. Finally, the essay seeks to respond to two central questions: why weren't foreigners given the right to citizenship and to vote? What were the effects on the political system?

El Sistema Municipal de Epidemiología definió en el marco de un proceso intersectorial y coparticipativo entre Estado y Comunidad, acciones de promoción y prevención dirigidas a lograr la cooperación efectiva de la población en la eliminación de criaderos potenciales del vector. Se inició así en el año 2000, un proceso, con diversos grados de intervención estatal, centrando el trabajo en la acción de promotores domiciliarios, que acercaron conocimientos a los ciudadanos sobre el Dengue y su vector transmisor. Se recabó, además información para evaluar el riesgo asociado a la presencia de criaderos. La actividad se extendió a establecimientos educacionales y organizaciones barriales.

    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.

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

    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.

  2. Argentina, regional training center on radiation protection for Latin America

    International Nuclear Information System (INIS)

    Argentina has an extensive background in education and training on Radiation Protection. Since the beginning of the nuclear activity in the country, prominence was given to the aspects related to radiation protection and training of the personnel involved in the use of ionizing radiation. These educative activities have been delivered for more than 50 years, having accumulated an important experience in the field. The Nuclear Regulatory Authority has the statutory obligation to address, among other matters, the control of the aspects of nuclear safety and radiation protection on the whole country, to protect the people of the harmful effects of ionizing radiation resulting from the nuclear activities. This includes the responsibility to develop and enforce the regulations, standards and other requirements, particularly, establishing the requests and promoting activities regarding education and training on radiation protection. Argentina, currently through the Nuclear Regulatory Authority, has performed postgraduate courses on radiation protection and nuclear safety at inter regional and regional level for 28 years without interruption. This important experience has been valued and exploited to form a Regional Center on Education and Training for Latin America and the Caribbean, sponsored by the International Atomic Energy Agency. The Regional Center that in fact has been running in Argentina, trained 404 foreign participants and 327 local participants since 1980, totalizing 731 graduates from our annual post graduate courses. Our commitment is that all the effort made in education and training on radiation protection and nuclear safety contributes to a better use of the benefits of nuclear development. Since 2001 the International Atomic Energy Agency raised the need to develop plans and establish agreements to ensure a long-term sustainability of the education and training programs, allowing a better use of the resources in this area. In order to achieve this goal

    The arrival of Albert Einstein in Argentina in 1925 had an impact, equally relevant, on the scientific community and on the general public. In this paper we discuss that visit from three different perspectives. Firstly, we consider the conditions that allowed for such visit to be possible. Then we focus on the institutional actors that facilitated it, as well as on the expertise and written references on topics related to relativity theory circulating at the time in the local community. In the last section we consider the implications of that visit for the local scientific environment.

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

  10. Dosimetric itercomparison programme for Co-60 therapy units in Argentina

    International Nuclear Information System (INIS)

    Thermoluminescence dosimeters (TLD) are widely used to verify absorbed dose delivered from radiation therapy beams. The Regional Reference Center (RRC) for Dosimetry of Argentina uses TLD for its mailed dose intercomparison programme for cobalt 60 radiation therapy units. Results obtained since 1978 as well as causes of dose discrepancies greater than 5% are analyzed. Results of the external quality control performed by the IAEA for this programme indicate that the dose evaluated by the RRC TLD service for the participating centers is about 1% lower than that evaluated by the IAEA TLD service. This deviation is accepted taking into account that a ± 2% dose uncertainty for TLD dosimetry is reasonable. (author)

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

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

    International Nuclear Information System (INIS)

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

    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.

  1. Occupational radiation exposures at radioactive and nuclear facilities in Argentina

    International Nuclear Information System (INIS)

    This paper presents an evaluation of occupational radiation exposures at relevant radioactive and nuclear facilities in Argentina, for 1996. The facilities send this information to the Nuclear Regulatory Authority due to the requirements included in their operation licenses and authorizations. Dose distributions of 1891 workers and their parameters are presented. The analysis is performed for each type of the following practices: nuclear power plants, research reactors, radioisotope production, fuel fabrication, industrial irradiation and research in the nuclear fuel cycle. Trends of occupational exposure in different practices are analysed and the highest doses have been identified. Following the 1990 recommendations of the International Commission on Radiological Protection (ICRP 60), the Nuclear Regulatory Authority of Argentina updated the dose limits for workers in 1995. The individual dose limits are 20 mSv per year averaged over five consecutive years (100 mSv in 5 years), not exceeding 50 mSv in a single year. To evaluate the occupational radiation exposure trend, without taking into account practices, an analysis of the distribution of individual doses accumulated in the period 1995/96, for all workers, is performed. Individual doses received during 1996 were all below 50 mSv and doses accumulated in the period 1995/96 were below 100 mSv. (author). 7 refs., 16 figs., 5 tabs

    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.

  3. Impact of new environmental and safety regulations in Argentina

    International Nuclear Information System (INIS)

    Mining and processing of uranium ore has been carried out since the early fifties at several locations in Argentina. For the purpose of this presentation only the Malargue Complex will be discussed. The second facility that will be discussed is the Cordoba Complex where uranium oxide is being produced. Since 1986, the Malargue Complex is no longer in operation and is in the process of being decommissioned and rehabilitated. Both facilities are owned and operated by the Government's Comision Nacional de Energia Atomica (CNEA). Two Government agencies are responsible for the implementation of the newly established Nuclear Law (Ley Nuclear), the Comision Nacional de Energia Atomica and the Autoridad Regulatoria Nuclear (ARN). The new law follows well established international standards for radiological safety. Furthermore, any mining operation in Argentina is also governed by the country's established Mining Code. Under these regulations any new proposals will have to submit environmental impact assessments and the required public hearings before it can be approved. Thus avoiding past mistakes where practically no precautions were taken during the planning or operation stages. (author)

  4. Present and Future Activities on Neutron Imaging in Argentina

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

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

  5. Transmission pricing and expansion methodology: lessons from Argentina

    International Nuclear Information System (INIS)

    This paper focuses on the pricing of electric transmission service in Argentina and on the mechanisms for expanding the transmission system as of late 1998. We also discuss the pricing of energy and generating capacity, since locational differences in their prices constitute charges for transmission service. We find that the methods in place for pricing transmission service are, in the main, consistent with the principles of efficient pricing but that the incentives and mechanisms established for expanding transmission are deficient in some respects. Most notable is the failure to provide for transmission rights, given the system's heavy reliance on user-driven expansion. We find that Argentina can improve upon its pioneering effort to implement user-driven expansion and indeed is exploring ways to do so. The most important tasks are to investigate (a) whether a system of financial transmission rights can be made to work as part of the process of user-driven expansion and (b) whether a backstop role for centrally planned expansion can be preserved without inhibiting or preempting the user-driven process.

    The aim of this paper is to analyze the relationship between excess weight and the condition of disability among elderly people in Argentina and to assess the extent to which a protective factor could be operating that reduces or mitigates the effect of overweight on the loss of functional skills in people over 64 years of age. In order to do so, microdata from Argentina's 2009 National Survey of Risk Factors [Encuesta Nacional de Factores de Riesgo] was utilized. To measure the association among overweight, obesity and disability status, as well as the interaction of weight status and age, logistic regression models were estimated. The results indicate that although overweight and obesity have a positive net effect on the occurrence of disabilities, this effect is lower among people 64 years of age and older. This result could be suggesting that among older people a protective factor is at work that, while not reversing the direct relationship between excess weight and disability, seems to attenuate it.

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

    2014-11-01

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

  8. Transmission expansion in Argentina 4: A review of performance

    International Nuclear Information System (INIS)

    In 1992 Argentina's electricity reform provided an innovative approach to transmission expansion. In particular, major expansions were determined by the Public Contest method - that is, by votes of transmission users rather than by the transmission company or the regulatory body - and then put out to competitive tender. This paper reviews the overall performance of that policy. There was substantial new transmission investment, especially in control systems and transformers rather than extra-high-voltage lines: an achievement of the policy lies in making better use of the existing transmission system. The number and value of Public Contest transmission expansion projects were steadily growing over time until Argentina's economic crisis, particularly at sub-transmission level. Transactions costs were not a problem in the Public Contest method: the median number of voters was 5, and the process was generally characterised by harmony between participants rather than by discord. Distribution companies supported rather than obstructed the process, though there was scope to improve the provincial regulatory framework. There was effective competition to build and operate the expansions, with a median of 3 bids for each and the incumbent winning less than one fifth. Such competition roughly halved the cost of new lines. This contrasts with lines built under the present Federal Transmission Plan at two and a half times the previous cost

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)

  13. PET in Argentina: A pioneer project in Latin America

    International Nuclear Information System (INIS)

    This report describes in detail the work of planning, installation and operation for the first PET Center in Latin America. Situated in the city of Mendoza -1100 km west from Buenos Aires-, today it still represents a major challenge given the general infrastructure conditions and limited resources for the region. Our purpose is to share the experience of more than 15 years in this exciting field, so as to encourage and advise on the development of other PET facilities in Argentina and other countries. The interest in Positron Emission Tomography in Argentina dates from the mid-80's, as an early initiative of CNEA (National Atomic Energy Commission) and its associated company INVAP (Applied Research Inc.). However, it almost took a decade to consolidate a working PET center at the Nuclear Medicine School Foundation in Mendoza (FUESMEN), and to develop its main constituents: radionuclide production, radiochemistry lab and scanning unit. Such areas are integrated by a multidisciplinary team of physicists, engineers, radiochemists, technologists and nuclear medicine physicians

  10. Electricity reform in Argentina: Lessons for developing countries

    Energy Technology Data Exchange (ETDEWEB)

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

    2008-07-15

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

    Zunino, G.E.; Vaccaro, O.B.; Canevari, M.; Gardner, A.L.

    1995-01-01

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

  12. Academic education and training in Medical Physics in Argentina

    International Nuclear Information System (INIS)

    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)

    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.

  16. An option for the management of radioactive waste in Argentina

    International Nuclear Information System (INIS)

    Argentina has an active nuclear program, started in the 50's, which includes two nuclear power plants (NPPs) in operation and one under construction, providing 12% of power generated in the country. Together with eight research reactors, complete facilities at the front and back end of the fuel cycle, such as radioisotope production plants and supporting laboratories in four atomic centers with an extensive research and development (R and D) program and an independent nuclear regulatory authority, constitute the backbone of the country's nuclear activities, employing in total approximately 4500 people. These activities, together with the future decommissioning of nuclear facilities, generate a considerable amount of nuclear waste which needs to be treated properly according to international practices and standards. The safe management of these wastes has being always one of Comision Nacional de Energia Atomica's (CNEA) top priorities. (author)

  18. Management of LEU aluminum-clad spent fuel in Argentina

    International Nuclear Information System (INIS)

    Full text: At present, the research and production reactor RA-3 is the only one in Argentina that generates aluminum-clad spent fuel. It was converted to reduced enrichment uranium in 1989 using LEU U3O8 fuel elements, which were developed in CNEA in the frame of the Program on Reduced Enrichment for Research and Test Reactors. The management strategy for the RA-3 spent fuel is presented in regard to interim wet and dry storage and the treatment prior to disposal. Particularly, different alternatives are discussed in relation to the processes being considered for the treatment of the spent fuel. In principle, these processes could be adjusted for spent fuels containing different fuel materials, e.g. U3O8, U3Si2 or U-Mo. A brief description of the available facilities for the spent fuel treatment is presented. (author)

    Mercedes María Barros

    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.

  20. Neoliberal Crisis, Social Demands, and Foreign Policy in Kirchnerist Argentina*

    Directory of Open Access Journals (Sweden)

    Anabella Busso

    2016-06-01

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

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

    International Nuclear Information System (INIS)

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

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 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.

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

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

    International Nuclear Information System (INIS)

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

  11. Academic education and training in Medical Physics in Argentina

    International Nuclear Information System (INIS)

    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)

  13. Measurements of radon gas in dwellings of Argentina

    International Nuclear Information System (INIS)

    The concentration of radon gas in dwellings of several cities of Argentina was measured. For this purpose, different kind of detectors were used such as passive solid state nuclear track detectors, electrets and detectors which use activated charcoal. Since 1983, a total of 1630 dwellings were analysed. The cases monitored were dwellings where the main construction materials are reinforced concrete and brick. The average values found in each city are below 50 Bq/m3. The values above 200-Bqm3 are very few, and none of them is above 300 Bq/m3. The average value of radon gas in air dwellings in our country is 33 Bq/m3, with a geometric mean of 23 Bq/m3, corresponding to an annual effective dose of 0.83 mSv. (author)

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

    Sarcocystis spp. are protozoan parasites with a heteroxenous life cycle, which produce cysts in the muscle of herbivorous animals. In these animal species, sarcocystosis is frequently asymptomatic, although it may occur with high prevalence. Seven Sarcocystis spp. have been described in red deer (Cervus elephus). The aim of this study was to determine the prevalence of sarcocystosis, and to perform the morphological and molecular characterization of Sarcocystis spp. found in wild red deer of the Nahuel Huapi National Park (NHNP), Patagonia, Argentina. Full necropsies of 62 red deer killed by hunters in the NHNP and neighboring areas were performed. Samples of heart and skeletal muscle were examined histologically and selected samples were also examined by transmission electron microscopy (TEM), PCR and sequencing. Sarcocystis spp. thin walled cysts were detected in 62 % (38/62) of heart, and in 22 % (3/14) of skeletal muscle samples examined histologically. TEM revealed a smooth and thin cyst wall (≤1 μm), with scarce and separated ribbon-like protrusions. A total of three partial and one full 18S ribosomal RNA (rRNA) gene sequences were obtained, and showed the highest identity (≥99 %) with Sarcocystis taeniata, a species described in moose (Alces alces). The morphological and molecular results indicate that red deer in Argentina are frequently infected with S. taeniata, a species for which the definitive host is unknown. The present results also confirm that Sarcocystis spp. using cervids as intermediate host are not host-specific. Further studies are needed to improve the epidemiological knowledge of Sarcocystosis in red deer. PMID:26779923

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

    International Nuclear Information System (INIS)

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

  20. Sustainability of new uranium mining projects in Argentina

    International Nuclear Information System (INIS)

    The regulatory framework issued in the 1994-1995 period, connected mining activities in Argentina with international good environmental practices. Agreements between National Government and Provinces allow the application of the regulations, while Act No 24.585, the milestone about the matter, establishes the steps for the approval of the Report of Environmental Impact, on successive stages of the project. Specifically for uranium mining and milling, the assessment of the radiological protection aspects of the planned activities is assigned to the Nuclear Regulatory Authority. The National Atomic Energy Commission is at present carrying out two uranium mining projects, that involve the Sierra Pintada and Cerro Solo deposits. The goal of them is restart uranium production in the country in the medium term, by lowing the gap between indigenous and market uranium prices. The first one consists in updating the feasibility study of the, at present inactive, Sierra Pintada Production Center (Mendoza Province). Studies for improving the mining and treatment methods are performed in the project, co-ordinately with the investigation and forecast of mining waste and processing tailings management. Besides, the procedures will be determined taking into account the methodology to be applied when getting the closure stage, about the existing waste and tailings. Development of the Sierra de Pichinan District, Chubut Province (U-Mo), is the objective of the second project. It is remarkable that about Cerro Solo, the main ore deposit belonging to this area, at the prefeasibility stage, CNEA is currently encouraging private investment through a bidding process. Environmental studies are an important aspect of the activities carried out and planned in the area. As a conclusion, with regard uranium mining and milling activities in Argentina, the regulations and environmental technical-scientific knowledge are becoming friendly with the sustainable practice.

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

    International Nuclear Information System (INIS)

    Nuclear development in Argentina is closely related to the creation and evolution of the National Atomic Energy Commission (CNEA). The first part of this historical review covers the period of formation and consolidation of the nuclear activities in the country, i.e. the period between 1945 to approximately 1970. After the creation of the CNEA, in 1950, a research and training program was carried out in several fields such as experimental nuclear physics, inorganic and physical chemistry, nuclear and radiochemistry, metallurgy, nuclear reactors, electronics, geology, etc. In the fifties, a research reactor (RA1), the first in Latin America, was built by the CNEA, including its fuel elements. Twenty new radioisotopes were discovered in Buenos Aires using the Cockcroft-Walton accelerator and the synchrocyclotron that were installed in 1953 and 1954 respectively. A school of physics, now the Balseiro Institute, was created at the Bariloche Atomic Center in 1955. At the same time the uranium prospecting and mining was started in several regions of the country. Ore treatment and purification plants were also installed and by 1970 more than 100 tons of U3O8 were produced in Argentina. Small scale isotope production was carried out with the RA1 reactor and with the synchrocyclotron to partially cover the demand of radioisotopes in biomedical applications. The construction of a new reactor, the RA3, and a radioisotope production plant at the Ezeiza Atomic Center allowed by 1975 to supply more than 90% of the national demand of radioisotopes and radiopharmaceuticals. Radiation protection activities were also carried out together with the development of the regulations concerning the use of radioisotopes and radiations. (author)

    Impacts of changes in land use upon rainfall distribution and low-level circulation over subtropical Argentina are studied with a state-of-the art regional model (WRF, Weather Research Forecast model) in a downscaling mode, using various scenarios of soil moisture for a 10 day period. The selected case (starting January 29, 2003) was characterized by well-defined low level northerly flow that extended east of the Andes over subtropical latitudes. Four tests were conducted at 50 km horizontal resolution with 31 sigma levels, decreasing and increasing the soil moisture initial condition by 50% over the entire domain, 50 % reduction over northwest Argentina and 50% increase over South East South America. A control run with NCEP/GDAS initial conditions was used to assess the impact of the different soil moisture configurations. It was found that land-surface interactions are stronger when soil moisture is decreased, with a coherent reduction of precipitation over southern south America. Enhanced northerly winds are related to an increase in the zonal gradient of pressure at low levels. In contrast, when soil moisture is increased, no circulation changes are found, though there appears to be a local feedback effect between the land and precipitation The combined effects of changes in the circulation and in local stratification induced by soil wetness modifications, through variations in evaporation and CAPE, are as follows: there is a dynamical response in the dry run, essentially associated with a stronger LLJ, that involves decreased convergence in the northwestern portion of the domain and enhanced convergence at the exit region of the LLJ, which is displaced towards the south. This dynamical response is not as robust as that induced by changes in evaporation related to changes in soil moisture. These modifications also alter the stratification, in agreement with what has been found by other studies, resulting in coherent modifications of precipitation when

  3. Atmospheric quality in Argentina employing Tillandsia capillaris as biomonitor

    International Nuclear Information System (INIS)

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

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

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.

    2014-04-01

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

    The passive continental margin offshore Argentina has been investigated by numerous geophysical surveys conducted by the Federal Institute for Geoscience and Natural Resources. In this study we focus on the area located north of Falkland Plateau. There, the passive margin forms the transition between the sheared margin of the Falkland Plateau and the volcanic passive margin of southern Argentina. This study aims at achieving a more detailed image of the crustal structure along the continent-ocean transition. Also we want to decipher the influence of the plume (Tristan da Cunha) on the evolution of the continental margin. The seismic data were acquired during a marine geophysical survey in 2004 and edited with an improved processing sequence. The imaging involves the application of Prestack Depth Migration, which gives information about depth and interval velocities of the reflectors. In addition we combine our seismic section with information from magnetic and gravimetric measurements. In this study we present preliminary results. A first section gives insight in the structure of the crust along the continent ocean boundary. Landwards there is no clear evidence of extension, which can be inferred from graben structures. In the transition zone the breakup unconformity is tilted seawards. In this part it is covered by a sedimentary drift body, which reaches a maximum thickness of 4km. The drift body can be divided into several units. In the east the oceanic basement is highly dissected by faults. The sedimentary succession overlying the oceanic basement reaches a maximum thickness of 4km. Further processing will reveal more details about the upper crustal structure along the margin. In the future we want to investigate the structure of the lower crust based on refraction seismic measurements.

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

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

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

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

  2. Exploration for uranium in Argentina: New policies of reactivation

    International Nuclear Information System (INIS)

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

    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. Dans le contexte particulier d’une Argentine marquée par des difficultés d’accès à la propriété foncière pour une large part de la population, les parcs nationaux se révèlent être des outils pertinents, pour les populations autochtones, de recouvrement de leurs

  5. Regulatory aspects of the radioactive waste management in Argentina

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

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.

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. Esto confirma la protección conferida por la vacunación BCG al nacimiento, con alta y continuada cobertura.TB notification rate in infants and children 0-4 years was 24.3/ 100.000 in Argentina, in 2000, for a global incidence of 31.8/ 100.000. A 17% of all TB cases occurred in children (0-14 years, indicating a very active TB transmission. Usually TB is diagnosed when the disease is already advanced. Main criteria for the diagnosis are: a previous contact

    Full Text Available A lo largo de los aproximadamente 20 años de colección de material para el estudio del desarrollo floral de Ericaceae en los bosques subantárticos de Argentina, ocho de las nueve especies allí existentes fueron fácilmente encontradas. La excepción fue Gaultheria nubigena . Es una especie rara; cincuenta y dos años pasaron desde su colección en 1952 hasta una más reciente en 2004; en esta oportunidad fue encontrada en una nueva localidad. Se reiniciaron búsquedas durante diciembre de 2005 y enero de 2006 que resultaron en la ubicación de la especie en la nueva localidad (Lago Gutiérrez y en una de las ya conocidas (Cascada Los Alerces; ambas poblaciones sólo cuentan con siete a diez individuos. La mayoría de los lugares visitados, con un hábitat supuestamente adecuado para encontrar más poblaciones, dieron resultados negativos. De acuerdo a la información disponible hasta el momento, se la considera en la categoría Vulnerable (VU de la UICN.During approximately 20 years of collecting material for floral development studies of Ericaceae in the subantarctic forests of Argentina, eight species of the nine that occur there were easily found. The exception was G. nubigena . It is a rare species; fifty-two years have elapsed since its collection in 1952 and more recently in 2004 when it was found in a new locality. Renewed searches during Dec. 2005 and Jan. 2006 resulted in the location of the species in the new locality (Lago Gutiérrez and one of the previously known ones (Cascada Los Alerces; both populations consist of no more than seven to ten individuals. Most of the supposedly appropriate habitats visited in order to find new populations yielded negative results. According to the information available it will be considered as Vulnerable (VU in the IUCN categories.

    Full Text Available El desarrollo de la Antropología Forense en la Argentina se halla relacionado con el período de violaciones a los derechos humanos que sufrió el país entre el periodo 1976 y 1983, y no a una decisión académica o a la iniciativa del sistema medico legal. La necesidad de investigar científicamente crímenes cometidos por el Estado, con ocultamiento de cuerpos, y no hechos cometidos por particulares, hizo que la definición y el campo habitual de desarrollo de la disciplina en el mundo anglosajón, se ven transformados, para abarcar lo que habitualmente se conoce como investigación previa de la desaparición así como en enfatizar el contacto directo entre el antropólogo forense y los familiares de las victimas con sus comunidades. Los 25 años de trayectoria del Equipo Argentino de Antropología Forense (EAAF, con trabajos de investigación en más de 35 países del mundo, ejemplifican lo complejo que es el análisis forense de casos de violencia política, con connotaciones jurídicas, religiosas y culturales específicas, que no deben ser excluidas del contexto de trabajo.The development of the Forensic Anthropology in Argentina is related to the period of human rights violations that the country underwent between 1976 and 1983, and not to an academic decision or the initiative of the medical legal system. The necessity to investigate scientifically crimes committed by the State, with concealment of bodies, and not by individuals, did that the definition and the habitual field of development of the discipline in the Anglo-Saxon world, had to transform in order to include what habitually it is known as preliminary investigation of the disappearance as well as in emphasizing the direct relation between the forensic anthropologist and the relatives of the victims with its communities.

    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. PMID:25148081

  20. Characterization of agua de Ramon marbles, Cordoba Province, Argentina

    International Nuclear Information System (INIS)

    Agua de Ramon district is located in the NW of Cordoba, Argentina, between 3 49' and 30052' S and 65021' and 65024' W, in the Eastern Pampean Range setting. It was a very important tungsten district until the end of 1950'decade when tungsten mining became of no economic interest. The objective is to report for the first time the petrological, mineralogical and geochemical characteristics of several marble lenses located in the sourthern of the area. Marble outcrops are lenticular ranging from 1 m to 80 m in length and 0.50 m to 20 m width. They appear massive, fine-grained and in light colors (white, pale green, very light brown and pale gray). These last varieties show a distinct banded structure due to little differences in color. These marbles are mainly composed of magnesian calcite accompanied by minor amounts of dolomite, forsterite, humite group minerals, tremolite, talc, serpentine and clinochlore, and scheelite, sphene, apatite and opaque minerals like hematite, magnetite, illmenite, pirrothite and pyrite as accessory minerals. Major chemical analyses indicate a relatively high SiO2 and MgO content, and minor CaO, in comparison with marbles of this type. Mineral paragenesis was useful to evaluate metamorphism conditions in this area
