    1987-01-01

    Within the frame of the tasks developed by the Argentine-Brazilian Contractors Coordination Committee in the nuclear area, which was at the beginning promoted by the Contractor Committee of the Argentine Association of Nuclear Technology, a working team was created between both countries in order to analyze the existing regulations and the Quality Assurance systems applied in Brazil and Argentina for their nuclear projects. This paper describes the steps to be followed so as to fulfill the compatibility of the rules, quality assurance and firm certification, laboratories, personnel and materials, and the applicable quality assurance programmes. At first, the methodology applied was the collection of the information and the existing regulations in each one of the countries, to exchange them, analyze them and arrange joint meetings and organize a seminar with experts from both countries to develop and discuss the objectives of this working team. As a result of these activities, the criteria adopted will allow, together with another actions, that both Argentine and Brazilian firms make exchanges and integrations in the nuclear field to supply Atucha II and Angra II.

  15. Trail pheromone of the Argentine ant, Linepithema humile (Mayr (Hymenoptera: Formicidae.

    Directory of Open Access Journals (Sweden)

    Dong-Hwan Choe

    Full Text Available The Argentine ant (Linepithema humile is recognized as one of the world's most damaging invasive species. One reason for the ecological dominance of introduced Argentine ant populations is their ability to dominate food and habitat resources through the rapid mobilization and recruitment of thousands of workers. More than 30 years ago, studies showed that (Z-9-hexadecenal strongly attracted Argentine ant workers in a multi-choice olfactometer, suggesting that (Z-9-hexadecenal might be the trail pheromone, or a component of a trail pheromone mixture. Since then, numerous studies have considered (Z-9-hexadecenal as the key component of the Argentine ant trails. Here, we report the first chemical analyses of the trails laid by living Argentine ants and find that (Z-9-hexadecenal is not present in a detectible quantity. Instead, two iridoids, dolichodial and iridomyrmecin, appear to be the primary chemical constituents of the trails. Laboratory choice tests confirmed that Argentine ants were attracted to artificial trails comprised of these two chemicals significantly more often than control trails. Although (Z-9-hexadecenal was not detected in natural trails, supplementation of artificial dolichodial+iridomyrmecin trails with an extremely low concentraion of (Z-9-hexadecenal did increase the efficacy of the trail-following behavior. In stark contrast with previous dogma, our study suggests that dolichodial and iridomyrmecin are major components of the Argentine ant trail pheromone. (Z-9-hexadecenal may act in an additive manner with these iridoids, but it does not occur in detectable quantities in Argentine ant recruitment trails.

  17. Carbohydrate supply limits invasion of natural communities by Argentine ants.

    The ability of species to invade new habitats is often limited by various biotic and physical factors or interactions between the two. Invasive ants, frequently associated with human activities, flourish in disturbed urban and agricultural environments. However, their ability to invade and establish in natural habitats is more variable. This is particularly so for the invasive Argentine ant (Linepithema humile). While biotic resistance and low soil moisture limits their invasion of natural habitats in some instances, the effect of food availability has been poorly explored. We conducted field experiments to determine if resource availability limits the spread and persistence of Argentine ants in remnant natural forest in North Carolina. Replicated transects paired with and without sucrose solution feeding stations were run from invaded urban edges into forest remnants and compared over time using baits and direct counts at feeding stations. Repeated under different timing regimes in 2006 and 2007, access to sucrose increased local Argentine ant abundances (1.6-2.5 fold) and facilitated their progression into the forest up to 73 +/- 21% of 50-m transects. Resource removal caused an expected decrease in Argentine ant densities in 2006, in conjunction with their retreat to the urban/forest boundary. However, in 2007, Argentine ant numbers unexpectedly continued to increase in the absence of sugar stations, possibly through access to alternative resources or conditions not available the previous year such as honeydew-excreting Hemiptera. Our results showed that supplementing carbohydrate supply facilitates invasion of natural habitat by Argentine ants. This is particularly evident where Argentine ants continued to thrive following sugar station removal.

    No other figure was able to organize and catalyze the seminal interest of space exploration in Argentina more than Teófilo Tabanera. Born in 1909, Tabanera showed an early interest in the possibilities of space travel and dedicated most of his life to popularize it in his country. He created the Sociedad Argentina Interplanetaria (1949), which was the first space enthusiast's organization in Latin America. Present in the first meeting of representatives of various space societies, which led to the creation of the International Astronautical Federation, Tabanera was able to bring his enthusiasm to this new organization. A prolific writer, Tabanera wrote the first books about space exploration in Spanish, and organized many courses and conferences on the subject. When the Comisión Nacional de Investigaciones Espaciales (the Argentine Space Agency) was created in 1960 by a decree of President Arturo Frondizi, Tabanera was appointed as its first administrator. There, with meager funds, he organized launch campaigns and international projects on sounding rockets. Thanks to his knowledge of the international space sector, Tabanera invited many experts to Argentina, among them Wernher von Braun and even the Apollo XI crew, just a few months after their return from the Moon. He continued his activities in the IAF (International Astronautical Federation) serving as vice president for seven terms, and was a cofounder of the International Academy of Astronautics (I.A.A.). His many contributions, both to the Argentine and international space sector, are a testimony to his undying enthusiasm and interest in space as a way of advancing humankind.

    Full Text Available The paper deals with bilateral relations between Argentina and Chile in recent decades, highlighting the potential of their new border relations. It assumes that the wide range of governmental actors, subnational and local entities linking each other have given this a unique dynamic border and are considered spaces of cooperation. The article is descriptive-reflective and is organized around a series of questions about the continued search for Argentine-Chilean border integration since the nineties and the construction of top-down and bottom-up institutional agreements. Within the variety of links, some remarkable examples are selected for the article like the "Integration Committees", the settlement of the Central West of South America Integration Zone (Zicosur and the Argentine-Chilean cooperation in Antarctica. It stresses the integrationist Maipú Treaty (2009 and institutions that charge different instances of bilateral dialogue.

    2010-11-01

    Cases of imposex have been reported for some organisms living in areas of the Argentine Atlantic coast. Since this is one of the known effects of the anti-fouling agent tributyltin (TBT), quantitative determinations of organotins in samples of water and sediments collected from sites along the Argentine coast were carried out. Severe cases of imposex were first reported for two gastropod species living in the Mar del Plata area, and determinations of TBT in samples collected from this site gave extremely high values and showed a close correlation between the degree of imposex and TBT concentration. Recent investigations in the area have shown a significant decrease. Surveys were also conducted in sites that exhibit highly irregular coastal profiles to examine the relevance of physical environments. Alarming concentrations of TBT were determined in most of the sites where heavy boat traffic and/or marine activities occur, demonstrating the urgent need for regulations to avoid further input of TBT. Reports from other sites in South America reveal that this should be a subject of regional concern in order to avoid severe damage to the biodiversity of regional marine organisms.

  7. Networks in Argentine agriculture: a multiple-case study approach

    Sebastián Senesi

    2013-06-01

    Full Text Available Argentina is among the four largest producers of soybeans, sunflower, corn, and wheat, among other agricultural products. Institutional and policy changes during the 1990s fostered the development of Argentine agriculture and the introduction of innovative process and product technologies (no-till, agrochemicals, GMO, GPS and new investments in modern, large-scale sunflower and soybean processing plants. In addition to technological changes, a "quiet revolution" occurred in the way agricultural production was carried out and organized: from self-production or ownership agriculture to a contract-based agriculture. The objective of this paper is to explore and describe the emergence of networks in the Argentine crop production sector. The paper presents and describes four cases that currently represent about 50% of total grain and oilseed production in Argentina: "informal hybrid form", "agricultural trust fund", "investor-oriented corporate structure", and "network of networks". In all cases, hybrid forms involve a group of actors linked by common objectives, mainly to gain scale, share resources, and improve the profitability of the business. Informal contracts seem to be the most common way of organizing the agriculture process, but using short-term contracts and sequential interfirm collaboration. Networks of networks involve long-term relationships and social development, and reciprocal interfirm collaboration. Agricultural trust fund and investor-oriented corporate structures have combined interfirm collaboration and medium-term relationships. These organizational forms are highly flexible and show a great capacity to adapt to challenges; they are competitive because they enjoy aligned incentives, flexibility, and adaptability.

    1999-01-01

    Full Text Available Many cattle breeds have been subjected to high selection pressure for production traits. Consequently, population genetic structure and allelic distribution could differ in breeds under high selection pressure compared to unselected breeds. Analysis of k-casein, aS1-casein and prolactin gene frequencies was made for Argentine Creole (AC and Argentine Holstein (AH cattle herds. The calculated FST values measured the degree of genetic differentiation of subpopulations, depending on the variances of gene frequencies.The AC breed had considerably more variation among herds at the aS1-casein and k-casein loci. Conservation strategies should consider the entire AC population in order to maintain the genetic variability found in this native breed.

    Kerr, Ashley

    2017-03-01

    In the late nineteenth century, Argentine intellectual elites turned to world’s fairs as a place to contest myths of Latin American racial inferiority and produce counternarratives of Argentine whiteness and modernity. This essay examines Argentine anthropological displays at three expositions between 1878 and 1892 to elucidate the mechanisms and reception of these projects. Florentino Ameghino, Francisco Moreno, and others worked deliberately and in conjunction with political authorities to erase the indigenous tribes from the national identity, even while using their bodies and products to create prehistory and garner intellectual legitimacy. Comparison of the three fairs also demonstrates how the representation of Amer-Indians and their artifacts shifted in accordance with local political needs and evolving international theories of anthropogenesis. The resulting analysis argues for the importance of considering the former colonies of the Global South in understanding the development of pre-twentieth-century anthropology and world’s fairs, particularly when separating them from their imperial context.

    Argentine population genetic structure was examined using a set of 78 ancestry informative markers (AIMs) to assess the contributions of European, Amerindian, and African ancestry in 94 individuals members of this population. Using the Bayesian clustering algorithm STRUCTURE, the mean European contribution was 78%, the Amerindian contribution was 19.4%, and the African contribution was 2.5%. Similar results were found using weighted least mean square method: European, 80.2%; Amerindian, 18.1%; and African, 1.7%. Consistent with previous studies the current results showed very few individuals (four of 94) with greater than 10% African admixture. Notably, when individual admixture was examined, the Amerindian and European admixture showed a very large variance and individual Amerindian contribution ranged from 1.5 to 84.5% in the 94 individual Argentine subjects. These results indicate that admixture must be considered when clinical epidemiology or case control genetic analyses are studied in this population. Moreover, the current study provides a set of informative SNPs that can be used to ascertain or control for this potentially hidden stratification. In addition, the large variance in admixture proportions in individual Argentine subjects shown by this study suggests that this population is appropriate for future admixture mapping studies.

    Full Text Available Abstract Background The Argentine ant, Linepithema humile, is a widespread invasive ant species that has successfully established in nearly all continents across the globe. Argentine ants are characterised by a social structure known as unicoloniality, where territorial boundaries between nests are absent and intraspecific aggression is rare. This is particularly pronounced in introduced populations and results in the formation of large and spatially expansive supercolonies. Although it is amongst the most well studied of invasive ants, very little work has been done on this ant in South Africa. In this first study, we investigate the population structure of Argentine ants in South Africa. We use behavioural (aggression tests and chemical (CHC approaches to investigate the population structure of Argentine ants within the Western Cape, identify the number of supercolonies and infer number of introductions. Results Both the aggression assays and chemical data revealed that the Western Cape Argentine ant population can be divided into two behaviourally and chemically distinct supercolonies. Intraspecific aggression was evident between the two supercolonies of Argentine ants with ants able to discriminate among conspecific non-nestmates. This discrimination is linked to the divergence in cuticular hydrocarbon profiles of ants originating from the two supercolonies. Conclusions The presence of these two distinct supercolonies is suggestive of at least two independent introductions of this ant within the Western Cape. Moreover, the pattern of colonisation observed in this study, with the two colonies interspersed, is in agreement with global patterns of Argentine ant invasions. Our findings are of interest because recent studies show that Argentine ants from South Africa are different from those identified in other introduced ranges and therefore provide an opportunity to further understand factors that determine the distributional and spread

    In 1997 an Intercomparison Program for individual monitoring started in order to test (on a voluntary basis) the performance in absorbed dose and personal dose equivalent determinations. The aim of the program was also to gain some insight into the general aspects related to the type of the personnel dosimeter used, the calibration procedures, the phantom spectral dependence and the management of radiological quantities. The Regional Reference Center for Dosimetry (CCR), of the Argentine National Atomic Energy Commission and the Physical Dosimetry Laboratory of the Argentine National Regulatory Authority, performed the irradiations. Those were done free air and on ICRU phantom, using X-ray, quality ISO: W60, W80, W110 and W200; and 137 Cs and 60 Co gamma rays, normal and angular (0, 30, 60 degrees) incidence. In the framework of the Program, an upgraded workshop took place and the national standard, IRAM 17146, was elaborated as well. In this work, the laboratories performance and its temporal evolution is shown from 1997 up to 2002. The suggestions to improve their performance are also included. (author)

    Argentine ants (Linepithema humile) live in groups of nests connected by trails to each other and to stable food sources. In a field study, we investigated whether some ants recruit directly from established, persistent trails to food sources, thus accelerating food collection. Our results indicate that Argentine ants recruit nestmates to food directly from persistent trails, and that the exponential increase in the arrival rate of ants at baits is faster than would be possible if recruited ants traveled from distant nests. Once ants find a new food source, they walk back and forth between the bait and sometimes share food by trophallaxis with nestmates on the trail. Recruiting ants from nearby persistent trails creates a dynamic circuit, like those found in other distributed systems, which facilitates a quick response to changes in available resources.

    2017-04-01

    This paper offers arguments to justify the relevance of psychoanalysis-psychoanalyses-in present-day Argentina and reflects on the stance taken by psychoanalysts with different theoretical perspectives in the face of the havoc wreaked by state terror (1976-1983). To this end, the author focuses on the pioneers' traits, the significance of the Argentine Psychoanalytic Association in the 1950s and 1960s, and the impact of the departure of the Plataforma Group in 1971. The establishment of the latter opened the way for the development of a psychoanalysis tied to popular movements, sensitive to social conflict, and close to human rights organizations. The author explores both on psychoanalysts' intervention to address the social trauma resulting from the theft of babies during the dictatorship, and on their relationship with Grandmothers of Plaza de Mayo.

    The 1993 annual report of the Brazilian Argentine Agency for Accounting and Control of Nuclear Materials, (ABACC), describes the activities regarding the administration and application of the Control and Accounting Common System (SCCC) established by the bilateral agreement between the Republic of Argentine and Federative Republic of Brazil for exclusive peaceful use of the nuclear energy. The main goal to verify practically all the installations which were not subjected to the international safeguards, before the agreement, was reached. Considering the safeguards application under implementation in both countries, the ABACC is preparing itself technically for the quadripartite agreement to be into force and signed among Argentine, Brazil, IAEA and ABACC. On checking the procedures established by the SCCC and controlled material, nothing was detected that could indicate nuclear material diversion either for nuclear weapon or for other explosive nuclear device.

    Full text:The aim of this Guide is the protection of the population from the risks derived from ionising radiations. The medical irradiations are the most important contribution to the human exposition to artificial ionising radiations. Since statistics indicate an increasing number of practices and facilities, the quality of these practices, its justification and its optimisation are a relevant topic for scientific societies and regulatory organisms. Since the 97/43/EURATOM Directive and the Malaga Conference most of the European countries implemented plans of action for patient radiological protection, including the search of consensus in relation to dose optimisation and the justification criteria for the indication of exams. An example of these is the Guide PR/118. In this context, three Meetings on Patient Radiological Protection took place in Argentina (initially organised by the Nuclear Regulatory Authority), where four work-groups were organised (Radiodiagnostics, Radiotherapy, Nuclear Medicine and Radiological Protection of Pregnant Women). Systematic activities began, with the institutional support of the Argentine Society of Radiology, that concluded with the elaboration of the 'Program for Patient Radiological Protection'. The analysis of the situation revealed a complex reality, that requires solutions of different degree of applicability. It was decided then to fix realistic goals for the short term that could be reached quickly with the available resources in order to obtain a modest but continuous advance without waking-up false expectations. One of the short term objectives was to start up a system to guarantee the justification of the practice, with five steps: the first is the preparation of a Guide of Recommendations (fulfilled stage); the second is to look for the validation and consensus from professional societies of other medical specialties (developing stage); the third is the diffusion, information, promotion and qualification in the use

    Trail pheromone disruption of invasive ants is a novel tactic that builds on the development of pheromone-based pest management in other insects. Argentine ant trail pheromone, (Z)-9-hexadecenal, was formulated as a micro-encapsulated sprayable particle and applied against Argentine ant populations in 400 m2 field plots in Hawai'i Volcanoes National Park. A widely dispersed point source strategy for trail pheromone disruption was used. Traffic rates of ants in bioassays of treated filter paper, protected from rainfall and sunlight, indicated the presence of behaviorally significant quantities of pheromone being released from the formulation for up to 59 days. The proportion of plots, under trade wind conditions (2-3 m s-1), with visible trails was reduced for up to 14 days following treatment, and the number of foraging ants at randomly placed tuna-bait cards was similarly reduced. The success of these trail pheromone disruption trials in a natural ecosystem highlights the potential of this method for control of invasive ant species in this and other environments. ??

    The Argentine margin presents a strong segmentation with considerable strike-slip movements along the fracture zones. We focus on the volcanic segment (between the Salado and Colorado transfer zones), which is characterized by seaward dipping reflectors (SDR) all along the ocean-continent transition [e.g. Franke et al., 2006; Gladczenko et al., 1997; Hinz et al., 1999]. The segment is structured by E-W trending basins, which differs from the South African margin basins and cannot be explained by classical models of rifting. Thus the study of the relationship between the basins and the Argentine margin itself will allow the understanding of their contemporary development. Moreover the comparison of the conjugate margins suggests a particular evolution of rifting and break-up. We firstly focus on the Colorado Basin, which is thought to be the conjugate of the well studied Orange Basin [Hirsch et al., 2009] at the South African margin [e.g. Franke et al., 2006]. This work presents results of a combined approach using seismic interpretation and structural, isostatic and thermal modelling highlighting the structure of the crust. The seismic interpretation shows two rift-related discordances: one intra syn-rift and the break-up unconformity. The overlying sediments of the sag phase are less deformed (no sedimentary wedges) and accumulated before the generation of oceanic crust. The axis of the Colorado Basin trends E-W in the western part, where the deepest pre-rift series are preserved. In contrast, the basin axis turns to a NW-SE direction in its eastern part, where mainly post-rift sediments accumulated. The most distal part reaches the margin slope and opens into the oceanic basin. The general basin direction is almost orthogonal to the present-day margin trend. The most frequent hypothesis explaining this geometry is that the Colorado Basin is an aborted rift resulting from a previous RRR triple junction [e.g. Franke et al., 2002]. The structural interpretation

    To study habitat use and at-sea movements of southern giant petrels (SGP) during non-breeding period, we deployed 15 satellite transmitters (six adults, nine juveniles) at Isla Arce and Isla Gran Robredo colonies in Patagonia, Argentina. Birds were instrumented during 81.4 ± 37 days. Adult birds used 74% of the Argentine shelf concentrating mainly at the shelf break, middle shelf waters, and the surroundings of the colony. After fledging, juveniles spread to the Argentine, Uruguayan and Brazilian shelves within the South Atlantic. Adults alternated at-sea excursions (12 ± 5 days) with periods at the colony of 3 ± 0.3 days. Contrarily, juveniles moved first to the shelf break and then traveled northwards reaching the south of Brazil. There was some spatial overlap between age classes, but only during the first 30 days after juveniles had fledged; thereafter there was not overlap between the areas used by both age classes. The Argentine shelf is widely used by different species offering a suitable environment for foraging; this may be why adults SGP from Patagonian colonies spend all year-round within the Argentine shelf. The identification of used areas of non-breeding SGP fills a gap in the species knowledge contributing not only to the preservation the species, but also to the management of marine areas globally recognized as important for many other Procellariiformes.

    1. The Haleakala Argentine Ant Project is an ongoing effort to study the ecology of the invasive Argentine ant in the park, and if possible to develop a strategy to control this destructive species. 2. Past research has demonstrated that the Argentine ant causes very significant impacts on native arthropods where it invades, threatening a large portion of the park’s biodiversity in subalpine shrubland and alpine aeolian ecosystems. 3. Patterns of spread over the past 30+ years indicate that the invasion process is influenced to a substantial degree by abiotic factors such as elevation, rainfall and temperature, and that the ant has not reached its potential range. Predictions of total range in the park suggest that it has only invaded a small fraction of available suitable habitat, confirming that this species is one of most serious threats to the park’s natural resources. 4. Numerous experiments have been conducted since 1994 in an attempt to develop a method for eradicating the Argentine ant at Haleakala using pesticidal ant baits. Thirty baits have been screened for attractiveness to ants in the park, and ten of these were tested for effectiveness of control in field plots. While some of these baits have been very effective in reducing numbers of ants, none has been able to eliminate all nests in experimental plots. 5. Research into a secondary management goal of ant population containment was initiated in 1996. By treating only expanding margins of the park’s two ant populations with an ant pesticide, rates of outward spread were substantially reduced in some areas. While this strategy was implemented from 1997 to 2004, it was ultimately discontinued after 2004 because of the difficulty and insufficient effectiveness of the technique. 6. In order to achieve the types of results necessary for eradication, the project would probably need to explore the possibility of developing a specialized bait, rather than relying on a commercially produced bait.

    The Argentine nuclear programme, as it stands at present, provides for the construction of four nuclear power plants in addition to those of Atucha I and Embalse and for the establishment of such fuel cycle facilities as are required to supply all of these plants. This paper evaluates the radiological impact (collective dose commitment) expected from the management of the radioactive wastes arising in the facilities mentioned above throughout the useful life of the reactors. The maximum individual doses to be expected as a result of the planned high-level-waste repository are also estimated. The evaluations presented are partly specific to the sites under consideration, but they also include estimates of the total collective dose commitments resulting from the management of radioactive waste under the Argentine nuclear programme.

    Since its creation in 1967, the Argentine Radiation Protection Society (SAR) promotes all the radiation protection and nuclear safety aspects not only within the scientific, technical and academic areas, but also to general public. To fulfill this objective, SAR organised training and refresher courses, seminars and workshops on RP subjects. During 2002, SAR organised 7 basic and specialized courses regarding the uses of radioactive materials in industrial applications and the course on medical response in radiological accidents, that was attended by Argentine and other Latin American participants. The programmes of the courses are developed in compliance with the legal requirements and also considering specifics needs. In this paper, the characteristics of the courses are enunciated and basic statistics regarding courses and participants are presented. For the 2003 and 2004, SAR foresees the organisation of 18 courses per year and has the capacity to deliver other courses by request. all the courses are delivered in Spanish language. Based on this educational experience SAR consider a priority the inclusion, of a RP module in all the scientific graduate programmes to generate awareness on the importance of RP. Taking into account the migration of professionals to Europe and North America and the Globalization, SAR advocates the harmonization of RP syllabus to attain an international recognition. (Author)

    Full Text Available 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 terres ancestrales, grâce en particulier aux processus de co-gestion participative mise en place sur ces territoires.

    Disruption of Argentine ant trail following and reduced ability to forage (measured by bait location success) was achieved after presentation of an oversupply of trail pheromone, (Z)-9-hexadecenal. Experiments tested single pheromone point sources and dispersion of a formulation in small field plots. Ant walking behavior was recorded and digitized by using video tracking, before and after presentation of trail pheromone. Ants showed changes in three parameters within seconds of treatment: (1) Ants on trails normally showed a unimodal frequency distribution of walking track angles, but this pattern disappeared after presentation of the trail pheromone; (2) ants showed initial high trail integrity on a range of untreated substrates from painted walls to wooden or concrete floors, but this was significantly reduced following presentation of a point source of pheromone; (3) the number of ants in the pheromone-treated area increased over time, as recruitment apparently exceeded departures. To test trail disruption in small outdoor plots, the trail pheromone was formulated with carnuba wax-coated quartz laboratory sand (1 g quartz sand/0.2 g wax/1 mg pheromone). The pheromone formulation, with a half-life of 30 h, was applied by rotary spreader at four rates (0, 2.5, 7.5, and 25 mg pheromone/m2) to 1- and 4-m2 plots in Volcanoes National Park, Hawaii. Ant counts at bait cards in treated plots were significantly reduced compared to controls on the day of treatment, and there was a significant reduction in ant foraging for 2 days. These results show that trail pheromone disruption of Argentine ants is possible, but a much more durable formulation is needed before nest-level impacts can be expected. ?? 2008 Springer Science+Business Media, LLC.

  11. Nuclear trade: An approach to the Argentine situation

    Antoniotti, A.A.; Paez, M.R.

    2006-01-01

    Under the Argentine nuclear trade regime, from the early stages of nuclear development an actual and strict monopoly governed the transfer of nuclear materials. That meant that the Federal State took the control as user, producer, purchaser or seller. This policy was inspired and clearly echoed by similar ones developed by other countries with important development in the nuclear field. This paper discusses the types of contract on nuclear commerce, the relation with costs incurred by the nuclear industry, ways in which the Federal State intervenes in nuclear commerce, and comparative policies in other fields or products in Argentina.

    This research seeks to release the cultural traces (linguistic, literary, folk left by the intense Italian immigration flow to the country in contemporary Argentine writers such as Raschella, Gambaro and Barrella. The theoretical framework includes re-examination of concepts like “memory”, “culture”, “multiculturalism”, “exile”, “identity”, “sense of belonging”, and the incorporation of the meme notion, before properly tackling the texts of the aforementioned authors. Such semiotic bunches will eventually confirm hypotheses and lead to the conclusions. The corpus will account for a testimonial literature which shows the active status of a cultural stratum fed by the epic lived by the Italian immigrants in Argentine.

    Full Text Available Quatrième culture nationale, le tournesol approche les 6 millions de tonnes de graines récoltées par an et fait de l’Argentine le premier producteur mondial. L’augmentation de sa production est accompagnée par un essor remarquable des activités de trituration, concentrées dans les sites portuaires d’exportation. Du coup, l’Argentine se hisse également au rang de premier exportateur mondial des produits dérivés : huile et tourteaux. À l’avenir, le tournesol devrait continuer à se développer. Son aptitude à supporter des sols et des climats frais et secs lui permet de s’étendre au-delà de la Pampa humide, jusqu’au sud-ouest de la province de Buenos Aires, sa zone de prédilection qu’il investit de plus en plus, au fur et à mesure de la poussée du soja dans les autres zones pampéennes. L’utilisation de graines hybrides, précoces et de meilleur rendement, pourrait être complétée par l’emploi de graines transgéniques. Mais son expansion potentielle n’interviendra qu’à la condition de relever certains défis : le développement de nouvelles variétés, l’obtention d’une meilleure qualité pour les produits dérivés et l’amélioration des moyens logistiques de commercialisation et d’exportation.

  1. Transmission pricing in privately-owned electricity grids: An illustration from the Argentine electricity pool

    International Nuclear Information System (INIS)

    Abdala, Manuel A.

    2008-01-01

    The Argentine electricity reform of 1992 offers an interesting example of decentralized transmission pricing arrangements within a competitive system. This paper is a shortened version of an original analysis made in 1994 of the regulation of the Argentine transmission system, with emphasis on investment cost allocation rules. To make up for the limitation of short-run marginal cost (SRMC) pricing, incentives on service quality were put in place, including penalties for lack of line availability. The mechanism for capacity expansion, based on ad-hoc rules for allocations of investment costs, had the potential to produce non-optimal investment outcomes, as such rules ignored beneficiaries on the demand side. For fine tuning of this system, I proposed an alternative rule based on traditional welfare analysis that broadens the universe of identified beneficiaries, and thus can be expected to produce a fairer outcome on investment cost allocation, reducing the potential risks of non-optimal investment. A brief postscript comments on the paper from the perspective of 2007. (author)

  5. Progress of radiosterilization in the Argentine Republic

    Mariano, E.E.; Mugliaroli, H.A.

    1975-01-01

    The technological and economic advantages of radiation as a means of sterilization have led to a steady expansion of its use. With the significant increase in the radiosterilization of medical products, the health authorities have established standards for the use of radiation for that purpose. These standards will be incorporated in the next edition of the Argentine Pharmacopoeia. In general, Argentine legislation in this area is based on the IAEA's Code of Practice for Radiosterilization of Medical Products. The microbiology services of Argentina's National Atomic Energy Commission (CNEA) determine the number of viable microorganisms in each product and package the product before irradiation. The controls are carried out on random samples. At the same time, the chemistry laboratories carry out quality controls on new products which have received sterilizing doses of gamma radiation. The gas sterilization methods employed most widely in the industrial manufacture of thermolabile products involve the use of ethylene oxide or formaldehyde. The cost of this process is influenced considerably by the fact that Argentina has to import ethylene oxide. The low penetrating power of formaldehyde means that the package containing the product must still be open at the time of sterilization if an adequate safety margin is to be ensured; consequently, one needs sterile installations for the post-irradiation sealing of packages. The capital and operating coats of such installations are high. A comparison has been made of the costs of sterilizing 11000 m 3 of a product with a density of 0.1 g/cm 3 and the following relative values obtained: ethylene oxide, 399.2; formaldehyde, 947.5; gamma radiation, 166.0. Studies of the effects of sterilizing doses on certain pharmaceutical products have demonstrated that the radiosterilization of some drugs is possible. The CNEA has designed an installation for the radiosterilization of medical products; the installation would have a 500000-Ci

    Full Text Available The Easter Rising was a turning point in contemporary Irish history. Although it lasted for a few days, from Monday 24 to Saturday 29 April, 1916, it had great impact in Ireland itself, and it also aroused considerable interest in many other countries, particularly in those with a significant Irish community, as in the case of Argentina. The aim of this paper is to study the way in which the contemporary Argentine graphic media (published in Spanish and in English presented and commented about the events that took place in Dublin. While it will try to contribute to the knowledge of the global echoes of the Easter Rising, this analysis will seek to help in a better understanding of the ideas of the English-speaking groups in Argentina, and particularly of the Irish community in that country, a group formed mainly by Argentine-born people of Irish descent.

  7. Workers select mates for queens: a possible mechanism of gene flow restriction between supercolonies of the invasive Argentine ant

    Some invasive ants form large networks of mutually non-aggressive nests, i.e., supercolonies. The Argentine ant Linepithema humile forms much larger supercolonies in introduced ranges than in its native range. In both cases, it has been shown that little gene flow occurs between supercolonies of this species, though the mechanism of gene flow restriction is unknown. In this species, queens do not undertake nuptial flight, and males have to travel to foreign nests and cope with workers before gaining access to alien queens. In this study, we hypothesized that male Argentine ants receive interference from workers of alien supercolonies. To test this hypothesis, we conducted behavioral and chemical experiments using ants from two supercolonies in Japan. Workers attacked males from alien supercolonies but not those from their own supercolonies. The level of aggression against alien males was similar to that against alien workers. The frequency of severe aggression against alien males increased as the number of recipient workers increased. Cuticular hydrocarbon profiles, which serve as cues for nestmate recognition, of workers and males from the same supercolony were very similar. Workers are likely to distinguish alien males from males of their own supercolony using the profiles. It is predicted that males are subject to considerable aggression from workers when they intrude into the nests of alien supercolonies. This may be a mechanism underlying the restricted gene flow between supercolonies of Argentine ants. The Argentine ant may possess a distinctive reproductive system, where workers participate in selecting mates for their queens. We argue that the aggression of workers against alien males is a novel form of reproductive interference.

    The need to create in the Argentine public opinion new positives symbols and images on nuclear energy and on the benefits of its peaceful applications, is al present so important as the development of new technical tools to improve the nuclear industry. These positives symbols and imagines on nuclear energy must be created in the framework of a joint strategy of all the country's nuclear institutions as well as other public organizations, in view of the new nuclear plan recently announced. This joint strategy will permit to create not only the new positives symbols and images in the public opinion, but also to obtain the support of the mass media and new spaces for negotiation in the national, provincial and municipal levels.

    This paper describes the impact on particulate and 'greenhouse gases' emissions of substitution policies implemented by Argentine state-owned electric power stations. Those policies involve the substitution, on the one hand, of hydroelectric and nuclear energy for conventional thermal energy and, on the other hand, of natural gas for fuel oil, diesel oil and coal. As additional investments are required in conventional thermal power stations to prevent environmental pollution, the investment savings generated by substitution policies have been calculated. While the environmental impacts of hydroelectric, nuclear and natural gas facilities is locally significant and is experienced in geographical areas away from cities, there can be no doubt that the substitution policies implemented in the Argentine electricity sector have overall both ecological and economic benefits.

    2011-01-01

    'American foulbrood' is a disease that seriously affects bees. Honey may be contaminated with spores of the related bacteria, Paenibacillus larvae larvae, which is a great drawback for trade. The scientific literature reports that these spores, resistant to heat and chemicals, are inactivated in honey when it is irradiated al 10 kGy, being this treatment mandatory in the Republic of Southafrica. Irradiated food wholesomeness is endorsed by the World Health Organization. Considering that Argentina is an important honey producer and exporter, the aim of this work was to evaluate the effect of ionizing radiation on some of its commercial chemical parameters along storage time. Honeys with different characteristics, coming from five different regions of the country: Middle, Patagonia, North, Litoral, Humid Pampa, were provided by producers from a commission called 'Packaged honey' of the National Food, Fishery and Agriculture Ministry. Fifteen kg of each honey variety were packaged in 500 g polypropylene recipes with polyethylene lids, and irradiated at the semi industrial cobalt-60 facility of the Ezeiza Atomic Center, 500,000 Ci of activity, with doses of 0, 10 and 20 kilo Grays. Control and irradiated samples were stored at room temperature for 10 months. Some standardized chemical analysis required by the Argentine Food Code (AFC) were performed on the first, fourth and tenth storage months: water content, acidity, diastase content, reducing sugars, and hydroxymethylfurfural. Reducing sugars and diastase activity slightly diminished, and acidity slightly increased, along storage which is typical in this product; no significant differences were found between control and irradiated samples. Hydroxymethylfurfural values, related to aging or thermal abuse, diminished slightly though significantly due to irradiation, which would not affect the product quality as regulations require not to surpass a maximum value, 40 mg/kg in the AFC. So ionizing

    An assessment is made of the radiological impact resulting from the activities carried out so far under the Argentine Nuclear Programme, together with a prediction of the impact which could result from the future activities planned under that Programme. The average individual risks and the radiological detriment due to the various activities are determined in terms of the average individual effective dose equivalents and the collective effective dose equivalent commitments. The assessments cover exposures of occupationally exposed workers and the public. The data obtained indicate that both the risks and the resultant detriment are reasonably comparable with those derived from other similar programmes. Moreover, they clearly indicate that the radiological impact of the Programme is tending to decrease with time so that it can be assumed that the radiological impact per unit of practice will be even lower in future.

    2018-01-01

    In insect societies, chemical communication plays an important role in colony reproduction and individual social status. Many studies have indicated that cuticular hydrocarbons (CHCs) are the main chemical compounds encoding reproductive status. However, these studies have largely focused on queenless or monogynous species whose workers are capable of egg laying and have mainly explored the mechanisms underlying queen-worker or worker-worker reproductive conflicts. Less is known about what occurs in highly polygynous ant species with permanently sterile workers. Here, we used the Argentine ant as a model to examine the role of CHCs in communicating reproductive information in such insect societies. The Argentine ant is unicolonial, highly polygynous, and polydomous. We identified several CHCs whose presence and levels were correlated with queen age, reproductive status, and fertility. Our results also provide new insights into queen executions in the Argentine ant, a distinctive feature displayed by this species in its introduced range. Each spring, just before new sexuals appear, workers eliminate up to 90% of the mated queens in their colonies. We discovered that queens that survived execution had different CHC profiles from queens present before and during execution. More specifically, levels of some CHCs were higher in the survivors, suggesting that workers could eliminate queens based on their chemical profiles. In addition, queen CHC profiles differed based on season and species range (native vs. introduced). Overall, the results of this study provide new evidence that CHCs serve as queen signals and do more than just regulate worker reproduction. PMID:29470506

    Full text: Introduction: In commercial aviation the most important determinants of radiation exposure in humans are the altitude, latitude, flight duration and the solar cycle's period. This study was conducted to address this type of exposure trough radiation dosimetry. Method: The study was performed in the business-class cabin of an Airbus 340-200 aircraft, provided by Argentine Airlines, during 2 flights routes: New York-Miami-Buenos Aires (trans equatorial) and Buenos Aires-Auckland (circumpolar). Measurements addressed the electromagnetic spectrum or low Linear Energy Transfer (LET) and corpuscular radiation (High LET). The instruments used were an Ion Chamber (IC), to measure the ionizing component of radiation (i.e., gamma radiation), the SWENDI, to measure only the neutron component, and the Tissue Equivalent Proportional Counter (TEPC) for measuring all radiation types. Results: The routes' dose rates are presented in the table. TEPC rates agreed with the LET findings. The total dose rates of high latitude flights were higher than those of low latitude flights. The SWENDI (High LET) results for the flights over the equator, at low latitude, represented only 1/3 of the total radiation. The New York-Miami and Buenos Aires-Auckland flights, at high latitude, represented just under 1/2 of the Total radiation (-45%). Conclusion: Based on the results of this study, the annual dose rates of radiation exposure of air crew personnel serving on international flights offered by Argentine Airlines is between 3 and 7 mSv. This rate is higher than the maximum recommended for the general population by the International Commission on Radiological Protection (ICRP), which is 1 milli Sv./y. Therefore, these personnel must be officially considered 'Occupationally Exposed to Radiation' in way to provide the appropriate measures that must be implemented for their protection in accordance to ICRP guidelines.

    2017-08-01

    Full Text Available The article analyzes cultural change related to the consumption of wild edible plants among Chorote Indians from Argentine Chaco, especially the process of construction of prejudices regarding such practices, expressed in the form of symbols of social or religious discredit which has led to their concomitant stigmatization and contempt. The influence of hegemonic agents in the conceptualization of wild edible plants and their utilization practices is here identified and analyzed from observational, exegetical and interpretative points of view. The article specifically discusses if the abandonment of wild edible plant consumption is due to reasons  linked to environmental determinism, to the mere acquisition of new cultural practices, or to socio-religious stigmatization of old food rules among Chorote Indians from Argentine Chaco.

    2006-01-01

    In 2006, the Argentine Nuclear Regulatory Authority has initiated a regulatory knowledge management process to face the loss of knowledge resulting from retiring experts, the generation gap, and the existing need to train new human resources. A number of projects have been started together with the technical assistance of the National Public Administration Institute to preserve knowledge and render it explicit for the coming generations. These projects include 'The History of the Expert's Learning Process' in which the majority of the most critical experts have been interviewed so far. The results of this project help envision a training structure and prospective projects. An Internet Site has also been created on the Intranet in order to render knowledge explicit and facilitate the tools for knowledge management initiatives. Furthermore, ARN's knowledge map project has also been started. (author) [es

    2016-01-01

    Full Text Available This paper analyses the different episodes that the Argentina wine industry transited between the years 1980 to 2012, within a context of globalization of the wine-grape industry. In particular, we study the significance that some winemakers had in the process and the effect of the exchange rate and recipients of Argentine wine in the expansion of exports in recent years. The hypothesis of this article is that, from the 80 s, the winemakers observed in exports as a solution to face their most important crisis. This required a transformation of the industry to produce quality wines that could be sold on the international market. Thus, winemakers added to a century-old winemaking tradition new practices and strategies. On the other hand, over 30 years, various macroeconomic policies affect the overall industry growth, especially in exports. On balance, in this paper we propose to show that the growth of exports of Argentine wine was a sinuous and different path to the literature has been found for the “new world” exporters countries. The data was obtained from Instituto Nancional de Vitivinícultura (INV, Bolsa de Comercio de Mendoza and International Organisation of Vine and Wine (OIV as well as interviews collected on primary and secondary sources.

  16. Equity during an economic crisis: financing of the Argentine health system.

    Cavagnero, Eleonora; Bilger, Marcel

    2010-07-01

    This article analyses the redistributive effect caused by health financing and the distribution of healthcare utilization in Argentina before and during the severe 2001/2002 economic crisis. Both dramatically changed during this period: the redistributive effect became much more positive and utilization shifted from pro-poor to pro-rich. This clearly demonstrates that when utilization is contingent on financing, changes can occur rapidly; and that an integrated approach is required when monitoring equity. From a policy perspective, the Argentine health system appears vulnerable to economic downturns mainly due to high reliance on out-of-pocket payments and the strong link between health insurance and employment.

  17. Simulation of the Argentine electric generation park and its possible expansion under the restriction of availability of fossil fuels

    2003-01-01

    MESSAGE program was used to simulate the Argentine electric generation park for 25 years, taking as a base the year 2000 and different scenarios of internal and external demand. As the Argentine electric system is strongly dependent on natural gas, the increase of the demand has been analyzed with, and without, the assumption of shortage of this fuel during the winter periods. Equipment and fuels already available have been selected to cover the increase of the demand taking into account technical and economic factors. The completion of Atucha II nuclear power plant, the increase of the water level of the hydroelectric Yacireta plant and natural gas combined-cycle plants are necessary even if no restrictions in the gas supply are foreseen. On the other hand new nuclear plants, new hydroelectric projects and gas oils fueled turbines will be necessary if natural gas shortage is assumed

    2012-08-01

    The efficacy of toxic baits should be judged by their ability to kill entire ant colonies, including the colony queen or queens. We studied the efficacy of four toxic baits to the Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae). These baits were Xstinguish that has the toxicant fipronil, Exterm-an-Ant that contains both boric acid and sodium borate, and Advion ant gel and Advion ant bait arena that both have indoxacarb. Experimental nests contained 300 workers and 10 queen ants that were starved for either 24 or 48 h before toxic bait exposure. The efficacy of the toxic baits was strongly influenced by starvation. In no treatment with 24-h starvation did we observe 100% worker death. After 24-h starvation three of the baits did not result in any queen deaths, with only Exterm-an-Ant producing an average of 25% mortality. In contrast, 100% queen and worker mortality was observed in colonies starved for 48 h and given Xstinguish or Exterm-an-Ant. The baits Advion ant gel and Advion ant bait arena were not effective against Argentine ants in these trials, resulting in ants are likely to be starved. Our results suggest queen mortality must be assessed in tests for toxic bait efficacy. Our data indicate that of these four baits, Xstinguish and Exterm-an-Ant are the best options for control of Argentine ants in New Zealand.

    Nowhere in Latin America has the privatization process been more aggressively pursued than in Argentina where President Carlos Menem has successfully turned over the bulk of state companies to the private sector. In the energy sector, that meant the divestiture in 1992 of Gas del Estado, the state-owned integrated gas transportation and distribution company. It was split in two transportation companies: Transportadora de Gas del Sur (TGS) and Transportadora de Gas del Norte (TGN), and eight distribution companies. TGS is the largest transporter of natural gas in Argentina, delivering more than 60 percent of that nation's total gas consumption with a capacity of 1.9 Bcf/d. This is the second in a series of Pipeline and Gas Journal special reports that discuss the evolving strategies of the natural gas industry as it continues to restructure amid deregulation. The article focuses on TGS, the Argentine pipeline system in which Enron Corp. is a key participant

    The development of effective baits to control the Argentine ant, Linepithema humile (Mayr), has been problematic because foragers prefer sweet liquids, while many toxicants are insoluble in water and liquid baits are generally difficult to deliver. The incorporation of thiamethoxam and sucrose solutions into a water-absorbing polyacrylamide hydrogel provides a unique and novel carrier and method of application for liquid baits. Formulations of thiamethoxam affected the size of the hydrogels, and sucrose solutions containing 0.0003% technical thiamethoxam provided hydrogels as large as those made with 25% sucrose solution or deionized water. Concentrations of thiamethoxam as low as 0.000075% in the hydrogels provided 50% kill of workers within 3 d in a laboratory setting. In small colony studies, baiting with 0.00015 and 0.000075% thiamethoxam hydrogels provided 100% mortality of workers and queens within 8 d. An enzyme-linked immunosorbent assay indicated that thiamethoxam was absorbed into the interior of the polyacrylamide matrix. The water loss rates of the hydrogels were dependent upon the relative humidity. Polyacrylamide hydrogels with >50% water loss were less attractive to ants. Field studies in highly infested areas indicated that concentrations of 0.0006 or 0.0018% thiamethoxam were more effective than 0.00015%. Hydrogels may provide a cost-effective alternative to providing aqueous baits to control Argentine ants. © The Authors 2015.

    The fish processing operations in Patagonia produce large amounts of waste. The main fishery resource in Argentina is the Argentine hake (Merluccius hubbsi). The ports of the province of Chubut (the most important of which are Puerto Madryn, Rawson and Comodoro Rivadavia), together with Caleta Paula Port (province of Santa Cruz), in the Argentine Patagonia, capture more than 82,000 tons of hake annualy, 80% of which are of M. hubbsi, which is mostly converted into fillets. From this capture, about 2,296 tons of liver would be available for the extraction of oil. To promote the recovery and industrial use of fish oil, in the present study, we determined the variation in the proximate composition and fatty acid profile of Argentine hake waste from the ports mentioned above at different catch times. Proximate composition was determined according of the Official Methods of Analysis (AOAC). Fatty acid profile was analyzed by gas chromatography of the fatty acid methyl esters (FAMEs). A standard mixture of FAMEs was run under identical conditions to identify the compounds on the basis of their retention times. Fatty acids were quantified using heptadecanoic acid (C17:0) as internal standard. The highest lipid recovery (27.0 to 41.8% of total lipids) was obtained from the liver fraction. Palmitic acid (C16:0), oleic acid (18:1 n9), docosahexaenoic acid (22:6 n3), eicosapentaenoic acid (20:5 n3) and palmitoleic acid (16:1) were the main constituents. Protein levels in viscera without livers (V-L) were higher than those in the liver. The extraction of marine fish oil and the production of fish offal meal from waste from fish factories would contribute to the sustainability of the regional industry, because it would also decrease the volume of waste, with benefits to the environment.

  8. Prosecuting International Crimes at National Level: Lessons from the Argentine ‘Truth-Finding Trials’

    Directory of Open Access Journals (Sweden)

    Elena Maculan

    2012-01-01

    Full Text Available Truth-finding trials (juicios por la verdad constitute a novel solution devised by the Argentine judicial system to cope with crimes committed by the past military dictatorship. This mechanism uses criminal courts as well as criminal procedure in order to investigate the truth about the dictatorship's crimes; however, the trials allow judges neither to establish criminal responsibility nor to punish the perpetrators of crimes. This limitation is due to the inability, imposed by the Full Stop and Due Obedience Laws, to prosecute the perpetrators of crimes.From the perspective of criminal law, truth-finding trials present two problematic features: firstly, their creation and regulation are set by judges, which has caused the development of many non-homogeneous local solutions and, secondly, their hybrid nature, which entails a possible subversion of conventional forms and goals in the context of the criminal trial.The paper also describes the current situation, since the Argentine impunity laws were declared unconstitutional and criminal proceedings reopened. The new framework provokes questions about the relationship between the reopened criminal trials and the truth-finding investigations, not only with regard to evidentiary issues but also with respect to the reason why the truth-finding investigations are still held.Finally, the shift from a non-punitive approach to the current full criminal accountability seems to suggest that truth-finding trials were merely a temporary solution, while the notion of the full prosecution and punishment of State crimes was never really set aside.

    The calculations were performed with SSYST-3 code system. The experiments have been carried out with shortened REBEKA simulators. The main goal was to verify whether the model for describing the Zircaloy cladding deformation and rupture at high temperatures (NORA2 model) is able to predict the Argentine cladding material behaviour under such conditions. A good agreement between experimental results and model predictions was found in the range of temperatures from 700 to 850 0 C (in α phase and first half of α+β transition phase). There were some discrepances at higher temperatures, probably due to the strong influence of heating rate on material properties. According to the results of these post-test calculations, it can be concluded that NORA2 model is able to well describe the Argentine Zircaloy cladding deformation and rupture under LOCA conditions, because there was a good agreement in the range of burst (ballooning) temperatures which are expected in this type of accident.

    Introduction: the study of biological subtype of breast cancer (B C) given by the expression tumor estrogen receptors (E R), progesterone (P R) and growth factor receptor and evolutionary. Objective: To know the profile of tumor expression of HER2, ER and P R and their relation with to characteristics clinico pathological characteristics in Uruguayan and Argentine patients with breast cancer. Material and Methods: The medical records of patients who underwent analyzed C M I-III invasive stages between 03/2006 and 03/2008 and assisted in Oncology Services where the authors are performing, which had selected determination ER, P R and HER2 by immunohistochemistry. The expression profile of these was markers compared with age at diagnosis, type and histological grade (GH) and pathological stage (TNM). Results: 291 patients (197 Uruguayan and 94 Argentine) were included whose characteristics were: mean age: 56 years, ductal carcinoma: 85%, GH 1-2: 55% stage I-II: 70%, metastasis axillary: 51%, ER / P R +: 78% HER2 + 12%. Three subtypes were defined: HER2 ER / P R + (71%), HER2 + (12% Uruguayan patients: 10%, Argentine patients: 17%) and negative Triple (TN) (17%). The joint analysis of the patients in both countries showed that subtypes TN and HER2 is associated with greater histological grade (p <0.05). Furthermore, in the group of patients Uruguayan, TN subtype was associated with younger age at diagnosis (p <0.05) subtype HER2, ER / PR +. Conclusions: The percentage of patients with CM Uruguayan invasive HER2 + subtype (10%) is smaller than that reported by other studies (17-28%) and that observed in our study Argentine group of patients. Consistent with previous studies, TN subtypes and HER2 + correlated with more undifferentiated tumors and in the group of Uruguayan patients TN appeared in younger patients

    2006-01-01

    Industrial gammagraphy has always been responsible for the highest rates of radiological incidents in almost every part of the world. This is mainly due to the high activities of the radioactive sources used, which are constantly transported in the equipment that contains them between the storage and the areas of work, and is also due to work load pressures which may induce to negligence in following the operational procedures, if a strong Safety Culture does not exist. The purpose of this paper is to present the main aspects of the argentine regulations relating to radiation protection to control this practice and to contribute in this way to reduce the associated risks. In addition, some incidents occurred in Argentina during the latest years, the causes that led to those events and their relation to the in observance of the regulations in force, their consequences and the measures taken to repair them are described. Finally, the importance of the role that education and training has in the strengthening of Safety Culture, key element of all undertaking, is highlighted. (author) [es

    Along the late 30 years spatial geodetic techniques enable us to measure horizontal and vertical deformations of the Earth’s surface with a very high precision. Performing this task we made Satellite Laser Ranging (SLR), and Global Positioning System (GPS) observations in South America ILRS 7406 Station placed at Observatorio Astronómico Félix Aguilar (OAFA) in San Juan, Argentina, accomplishing a Cooperation Agreement between CAS - NAOC and OAFA - UNSJ. Trough LAGEOS II Satellite observations we obtain rectangular coordinates of San Juan ILRS Station in the Terrestrial Reference Frame (ITR 2000), standing out that Argentine Station data were included in the late arrangements ITRF given by International Earth Rotation and Reference System Service (IERS). Spatial and temporary variations of the epoch 2010 - 2011 were evaluated finding out remarkable displacements, of about a half meter, related with seismic events on the region. We confirm these deformations by means of GP S determinations referred to Permanent GPS Station placed nearby the SLR Station.

    Brazil has been the most important MERCOSUL's purchaser of fresh onions from Argentina. The increased claim for this fresh product has forced a consensus between the members nations, as regards to phytosanitary restrictions. The radio inhibition is described on National Food Codes in Brazil and Argentina. Methods of food irradiation detection must be performed, since they increase the consumer confidence. Quick and simple screening tests indicate whether a food product has been irradiated or not. This present study verified the DNA fragments of argentine fresh onions, produced during radiation process and 6 months of storage period. The DNA fragments are analyzed for detection of irradiated foods. The irradiated onions presented extensive DNA migrations, as comets, when submitted to agarose gel electrophoresis. They also showed more shelf life compared to the unirradiated onions. The unirradiated samples exhibited only limited DNA migration. This initial screen method showed to be effective for detection of irradiated onions. (author)

    The influence of maintenance activities upon nuclear safety and their relevance as means to detect and prevent aging make them play an outstanding role among the fields of interest of the Argentine nuclear regulatory body (ENREN). Such interest is reinforced by the fact that the data obtained during maintenance are used - among other - as inputs in the Probabilistic Safety Analyses required for those nuclear power plants. This paper provides a brief description of the original requirements by the regulatory body concerning maintenance, of the factors that led to review the criteria involved in such requirements and of the key items identified during the reviewing process. The latter shall be taken into account in the maintenance regulatory policy, for the consequent issue of new requirements from the utilities and for the eventual publication of a specific regulatory standard.

    One of the most important and active pioneers of the space activities in Argentina was Miguel Sánchez Peña, an aeronautical engineer and an officer of the Argentine Air Force. Sánchez Peña was the organizer of Argentina's governmental space program in the 1970s and part of the 80s, and contributed immeasurably to the Nation's sounding rocket program. Born in Mendoza, Argentina in 1925, Sánchez Peña attended the Military Aviation School (Escuela de Aviación Militar) in Córdoba, and later the Air Force Engineering School. Graduated as an engineer in 1959 he was sent to the University of Michigan in the United States to complete his graduate studies earning a Masters of Science degree in Aerospace Engineering. There he had the opportunity to study with several future NASA astronauts such as Theodore Freeman, Edward White and James McDivitt. After his return to Argentina in 1961 he was put in charge of the Space Development Group (Grupo de Desarrollos Espaciales) of the Air Force in Córdoba. While with the Air Force he managed the development of a family of various sounding rockets for high altitude research. Sánchez Peña was also in charge of the first Argentine rockets launched from Antarctica in 1965, as well as the first tests on an Argentine-fabricated rocket (Orión) from Wallops Island in the United States, in 1966. The Orion was the first operational sounding rocket constructed in South America. In the middle of the 1970s Miguel Sánchez Peña was named president of the CNIE (National Space Research Commission). Starting with just a modest one-desk office at the Argentine Air Force headquarters, in only a few years he turned CNIE into a multi-center organization with several hundred employees, three operational launch centers across the country and a family of research rockets open to the international scientific community. He was also actively representing Argentina in many IAF congresses, and was a member of the International Academy of

    Cardiologists are involved in the management of patients with multiple cardiovascular risk factors and chronic heart diseases, so empathy is a necessary feature to deal with them. The aim of the study was to evaluate the validity and reliability of the Spanish version of the Jefferson Scale of Physician Empathy (JSPE) among Argentine cardiologists and to explore the potential differences by age, gender, and subspecialty. Between August and September 2012, we performed a survey in a non-randomized sample of 566 Spanish-speaking cardiologists of Argentina. A Principle Component Analysis (PCA) was used to explore the link between observed variables and latent variables in order to identify the factor structure. The PCA criteria for identifying the factor structure were examined with the Kaiser-Meyer-Olkin (KMO) analysis. The KMO measure of sampling adequacy was 0.86 and Bartlett's test of sphericity was highly significant (p = 0.000), determining the suitability of the data set for factor analysis. The PCA of 20 items yielded a three factor model that accounted for 40.6% of the variance. The JSPE mean rank score for women was 307.9 vs. 275.0 for men (p = 0.017). The comparison of mean rank score according to age (quartiles) showed a significant relation between older age and empathy. No difference was found when the mean rank scores were compared by respondent subspecialty. JSPE provides a valid and reliable scale to measure Argentine cardiologists' attitudes towards empathy. Female cardiologists seem to be more empathic than their male colleagues, and a positive relationship between age and empathy was found.

  19. Sulfur Cycling in an Iron Oxide-Dominated, Dynamic Marine Depositional System: The Argentine Continental Margin

    Full Text Available The interplay between sediment deposition patterns, organic matter type and the quantity and quality of reactive mineral phases determines the accumulation, speciation, and isotope composition of pore water and solid phase sulfur constituents in marine sediments. Here, we present the sulfur geochemistry of siliciclastic sediments from two sites along the Argentine continental slope—a system characterized by dynamic deposition and reworking, which result in non-steady state conditions. The two investigated sites have different depositional histories but have in common that reactive iron phases are abundant and that organic matter is refractory—conditions that result in low organoclastic sulfate reduction rates (SRR. Deposition of reworked, isotopically light pyrite and sulfurized organic matter appear to be important contributors to the sulfur inventory, with only minor addition of pyrite from organoclastic sulfate reduction above the sulfate-methane transition (SMT. Pore-water sulfide is limited to a narrow zone at the SMT. The core of that zone is dominated by pyrite accumulation. Iron monosulfide and elemental sulfur accumulate above and below this zone. Iron monosulfide precipitation is driven by the reaction of low amounts of hydrogen sulfide with ferrous iron and is in competition with the oxidation of sulfide by iron (oxyhydroxides to form elemental sulfur. The intervals marked by precipitation of intermediate sulfur phases at the margin of the zone with free sulfide are bordered by two distinct peaks in total organic sulfur (TOS. Organic matter sulfurization appears to precede pyrite formation in the iron-dominated margins of the sulfide zone, potentially linked to the presence of polysulfides formed by reaction between dissolved sulfide and elemental sulfur. Thus, SMTs can be hotspots for organic matter sulfurization in sulfide-limited, reactive iron-rich marine sedimentary systems. Furthermore, existence of elemental sulfur and iron

    Ovine cattle was introduced into America during the Spanish conquest with the second journey of Columbus to the Antilles and was disseminated throughout the region. In 1587, sheep were introduced into Argentina, later developing into the "Creole" breed. We selected 486 animals from different Argentine provinces with the aim of determining the serological status of brucellosis caused by Brucella melitensis and Brucella ovis. For the detection of antibodies against smooth Brucella spp., the Rose Bengal test (RBT) was performed as screening test while the serum agglutination test (SAT) and 2 mercapto-ethanol (2ME) were run as a confirmatory technique. Moreover, for the detection of antibodies against rough Brucella spp., we used the rapid slide agglutination test (RSAT) for screening and an indirect ELISA (IELISA) as confirmatory assay. This study showed that the total positive percentage of brucellosis due to B. ovis was 2.9%. Excluding the animals mixed with the Suffolk breed; seropositivity would be 0.6%. All animals tested negative for brucellosis caused by B. melitensis. Copyright © 2017 Asociación Argentina de Microbiología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Wolbachia are maternally inherited bacteria, which are very common in arthropods and nematodes. Wolbachia infection may affect host reproduction through feminisation, parthenogenesis, male-killing, cytoplasmic incompatibility and increased fecundity. Previous studies showing discrepancies between...... of Wolbachia were studied in three native and eight introduced populations of the Argentine ant Linepithema humile. The screening shows that the symbiont is common in the three native L. humile populations analysed. In contrast, Wolbachia was detected in only one of the introduced populations. The loss...... transmission of the symbiont may be important in ants as suggested by the sequence similarity of strains in the three genera Linepithema, Acromyrmex, and Solenopsis native from South and Central America....

    We studied the effect of estimated PM 10 on respiratory infections in children from Cordoba, Argentine as well as the influence of weather factors, socio-economic conditions and education. We analyzed upper and lower respiratory infections and applied a time-series analysis with a quasi-Poisson distribution link function. To control for seasonally varying factors we fitted cubic smoothing splines of date. We also examined community-specific parameters and differences in susceptibility by sex. We found a significant association between particles and respiratory infections. This relationship was affected by mean temperature, atmospheric pressure and wind speed. These effects were stronger in fall, winter and spring for upper respiratory infections while for lower respiratory infections the association was significant only during spring. Low socio-economic conditions and low education levels increased the risk of respiratory infections. These findings add useful information to understand the influence of airborne particles on children health in developing countries. - Highlights: ► Few information is available on children respiratory health from developing countries. ► We modeled the association between PM 10 and children's respiratory infections. ► We checked the influence of weather factors, socio-economic conditions, education and sex. ► Temperature, pressure and wind speed modified the effect of particles. ► Low socio-economic conditions and low education levels increased the risk of infections. - The concentration of airborne particles as well as low socio-economic conditions and low education levels are significant risk factors for upper and lower respiratory infections in children from Cordoba, Argentine.

  5. Development of virtual bait stations to control Argentine ants (Hymenoptera: Formicidae) in environmentally sensitive habitats.

    A novel bait station referred to as a virtual bait station was developed and tested against field populations of the invasive Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae), at White Beach, Camp Pendleton, in Oceanside, CA. White Beach is a nesting habitat for an endangered seabird, the California least tern (Sterna antillarum browni Mearns). The beach is heavily infested with Argentine ants, one of the threats for the California least tern chicks. Conventional pest control strategies are prohibited because of the existence of the protected bird species and the site's proximity to the ocean. The bait station consisted of a polyvinyl chloride pipe that was treated on the inside with fipronil insecticide at low concentrations to obtain delayed toxicity against ants. The pipe was provisioned with an inverted bottle of 25% sucrose solution, then capped, and buried in the sand. Foraging ants crossed the treated surface to consume the sucrose solution. The delayed toxicity of fipronil deposits allowed the ants to continue foraging on the sucrose solution and to interact with their nestmates, killing them within 3-5 d after exposure. Further modification of the bait station design minimized the accumulation of dead ants in the sucrose solution, significantly improving the longevity and efficacy of the bait station. The virtual bait station exploits the foraging behavior of the ants and provides a low impact approach to control ants in environmentally sensitive habitats. It excluded all insects except ants, required only milligram quantities of toxicant, and eliminated the problem of formulating toxicants into aqueous sugar baits.

    Larvae of the genus Pseudoterranova constitute a risk for human health when ingested through raw or undercooked fish. They can provoke pseudoterranovosis in humans, a fish-borne zoonotic disease whose pathogenicity varies with the species involved, making their correct specific identification a necessary step in the knowledge of this zoonosis. Larvae of Pseudoterranova decipiens s.l. have been reported in several fish species from off the Argentine coasts; however, there are no studies dealing with their specific identification in this region. Here, a genetic identification and morphological characterization of larval Pseudoterranova spp. from three fish species sampled from Argentine waters and from Notothenia coriiceps from Antarctic waters was carried out. Larvae were sequenced for their genetic/molecular identification, including the mitochondrial cytochrome c oxidase subunit II (mtDNA cox2), the first (ITS-1) and the second (ITS-2) internal transcribed spacers of the nuclear ribosomal DNA, and compared with all species of the P. decipiens (sensu lato) species complex (sequences available in GenBank). Further, adults of Pseudoterranova spp. from the definitive host, the southern sea lion, Otaria flavescens, from Argentine and Chilean coasts were sequenced at the same genes. The sequences obtained at the ITS-1 and ITS-2 genes from all the larvae examined from fish of Argentine waters, as well as the adult worms, matched 100% the sequences for the species P. cattani. The sequences obtained at mtDNA cox2 gene for Antarctic larvae matched 99% those available in GenBank for the sibling P. decipiens sp. E. Both MP and BI phylogenetic trees strongly supported P. cattani and P. decipiens sp. E as two distinct phylogenetic lineages and depicted the species P. decipiens sp. E as sister taxon to the remaining taxa of the P. decipiens complex. Larval morphometry was similar between specimens of P. cattani from Argentina, but significantly different from those of P

    The growth of telemedical applications and electronic transactions in health environments is paced by the constant technology evolution. This implies a big cultural change in traditional medicine and in hospital information systems' users which arrival is delayed, basically, by the lack of solid laws and a well defined role-based infrastructure. The use of digital signature as a mean of identification, authentication, confidentiality and non-repudiation is the most suitable tool for assuring the electronic transactions and patient's data protection. The implementation of a Public Key Infrastructure (PKI) in health environment allows for authentication, encryption and use of digital signature for assuring confidentiality and control of the movement of sensitive information. This work defines the minimum technological, legal and procedural basis for a successful PKI implementation and establishes the roles for the different actors in the chain of confidence in the public health environment of Argentine

    From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

Gamma rays are detected with a Ge(Li) detector and Nal scintillator both in singles and coincidences, a target of Cr has been exposed to the beam and the γ-spec- tra analyzed with the purpose of determining the Ge(Li) detector efficiency in the high energy range. Several target elements have been studied; Nd, Y, T,i and As, and branching ratios have been measured. In the particular case of Ti the experiment was carried out in an attempt to establish the existence of low lying excited states due to core excitations. The results of this investigation are being analyzed and will be published in the near future. A set-up for nuclear spectroscopy studies of short-lived, fission-produced radioisotopes became operative at the Argentine AEC, in Buenos Aires, around the beginning of 1969. The system is of the ISOL type, consisting in a continuous production and mass separation of the nuclei, followed by detection of the emitted radiation by means of solid-state detectors coupled to appropriate analysing devices.

    Full Text Available Background: Individuals living with Parkinson’s disease (PD can experience a range of movement disorders. Therapeutic dance is enjoyable and thought to improve mobility, balance and well being in some people with PD. The primary objective of this study was to evaluate the feasibility and safety of a 4 week Argentine tango dance program for people with PD. Methods: Six community dwelling individuals with mild-moderate PD were recruited from Parkinson’s support groups, movement disorder clinics and the Parkinson’s disease Association in Australia. To minimise falls risk, participants were required to be less than 75 years of age and physically independent (Hoehn and Yahr stages I-III. They were also required to speak English. Participants attended a 1 hour dance class at a dance studio twice per week for 4 weeks. A professional dance instructor led and choreographed the classes. Physiotherapists were present to assist participants during the class and served as dance partners as necessary. The primary outcome was feasibility which was determined by measures of recruitment, adherence, attrition, safety (falls, near misses and adverse events and resource requirements. Secondary measures included the Beck Depression Inventory and the Euroqol-5D, administered at baseline and post intervention. Therapy outcomes pre and post-intervention were analysed descriptively as medians and inter-quartile ranges and using Wilcoxon matched pair signed-rank tests.Results: The Argentine tango dance intervention was shown to be safe, with no adverse events. Adherence to the dance program was 89%. Depression scores improved after intervention (p=0.04. Some challenges were associated with the need to quickly recruitment participants and supplying physiotherapists to act as dance partners. Conclusion: The program was shown to be feasible and safe for people with mild to moderately severe PD.

    Pictures of facial expressions of emotion are used in a wide range of experiments. The last decade has seen an increase in the number of studies presenting local sets of emotion stimuli. However, only a few existing sets contain pictures of Latin Americans, despite the growing attention emotion research is receiving in this region. Here we present the development and validation of the Universidad Nacional de Cordoba, Expresiones de Emociones Faciales (UNCEEF), a Facial Action Coding System (FACS)-verified set of pictures of Argentineans expressing the six basic emotions, plus neutral expressions. FACS scores, recognition rates, Hu scores, and discrimination indices are reported. Evidence of convergent validity was obtained using the Pictures of Facial Affect in an Argentine sample. However, recognition accuracy was greater for UNCEEF. The importance of local sets of emotion pictures is discussed.

    The irradiation of the first Argentine prototypes of PHWR MOX fuels began in 1986. These experiments were made in the HFR-Petten reactor, Holland. The rods were prepared and controlled in the CNEA's facility. The postirradiation examinations were performed in the Kernforschungszentrum, Karlsruhe, Germany and in the JRC, Petten. The first rod has been used for destructive pre-irradiation analysis. The second one as a pathfinder to adjust systems in the HFR. Two additional rods including iodine doped pellets were intended to simulate 15000 MWd/T(M) burnup. The remaining two rods were irradiated until 15000 MWd/T(M) (BU15 experiment). One of them underwent a final ramp with the aim of verifying fabrication processes and studying the behaviour under power transients. BACO code was used to define the power histories and to analyze the experiments. This paper presents the postirradiation examinations for the BU15 experiments and a comparison with the BACO outputs for the rod that presented a failure during the ramp test of the BU15 experiment.

    Copepods play an important role in marine ecosystems as a direct link of energy transfer between primary producers and higher trophic level consumers, such as fish. In the Argentine Sea, the Patagonian stock of Argentine hake Merluccius hubbsi spawns from late austral spring (December) to early autumn (April) in the northern Patagonian shelf region (43°-45°30‧S), in association with a highly productive tidal front system. Since hake larvae prey mainly upon copepods, the objective of this study was to assess the spatial variability in the abundance and diversity of these potential food items in different sectors of the front, as one of the possible factors affecting hake recruitment success. Two complementary mesh sizes (67 and 300 μm) were used to accurately target the entire copepod size spectrum. The copepod community was dominated by developmental stages sustain M. hubbsi larval growth resulting from high availability of adequate prey, the suitable thermal ranges, and the existence of retention mechanisms.

    Full text: The purpose of this presentation is to point out some relevant issues related to the transport of cobalt 60 for domestic uses and export from the Argentine Nuclear Power Plant located in Embalse (ENPP). It is remarked that in last 22 years, ENPP produced about 2600 PBq (70 MCi) of Co-60, and that Argentina is the third Co-60 producer, after Canada and Russia. It is mentioned that in Argentina there are facilities which manufacture Zircaloy seamless tubes and reactivity control bars containing cobalt 59 to be used in ENPP, the operation of Candu reactor at ENPP including cobalt-related activities, and the manufacture and commercialization of Co-60 sealed sources. The Argentine Nuclear Regulatory Authority verifies the compliance of nuclear activities with regulatory standards, including those related to the transport of radioactive material. Then, it is described the process for obtaining Co-60 at ENPP with an activity concentration to allow its use in medicine and industry. After that, is considered in detail the type of package used for the transport of Co-60 from ENPP: it is to say, Type B(U) package designs that must be approved by the Competent Authority origin of the design, and they are able to withstand routine, normal and accident conditions of transport, including severe impacts, fires and immersion in water. The overall dimensions of packages are about 1.0 m to 1.5 m diameter by 1.2 m to 1.8 m high, as well as the gross mass could vary from 6500 kg to 9500 kg. Radioactive contents consist of Co-60 sealed sources (called pencils), with an activity range from 8 PBq to 16 PBq. Then, it is considered activities prior to dispatch of Type B(U) packages at ENPP, including the preparation of radioactive contents, packaging and package (labelling and marking) as well as necessary tests and documentation for transport in order to fulfil pertinent requirements of package design operation manual of the package and related standards. Finally, it is pointed

    The functions and compositions of symbiotic bacterial communities often correlate with host ecology. Yet cause-effect relationships and the order of symbiont vs. host change remain unclear in the face of ancient symbioses and conserved host ecology. Several groups of ants exemplify this challenge, as their low-nitrogen diets and specialized symbioses appear conserved and ancient. To address whether nitrogen-provisioning symbionts might be important in the early stages of ant trophic shifts, we studied bacteria from the Argentine ant, Linepithema humile - an invasive species that has transitioned towards greater consumption of sugar-rich, nitrogen-poor foods in parts of its introduced range. Bacteria were present at low densities in most L. humile workers, and among those yielding quality 16S rRNA amplicon sequencing data, we found just three symbionts to be common and dominant. Two, a Lactobacillus and an Acetobacteraceae species, were shared between native and introduced populations. The other, a Rickettsia, was found only in two introduced supercolonies. Across an eight-year period of trophic reduction in one introduced population, we found no change in symbionts, arguing against a relationship between natural dietary change and microbiome composition. Overall, our findings thus argue against major changes in symbiotic bacteria in association with the invasion and trophic shift of L. humile. In addition, genome content from close relatives of the identified symbionts suggests that just one can synthesize most essential amino acids; this bacterium was only modestly abundant in introduced populations, providing little support for a major role of nitrogen-provisioning symbioses in Argentine ant's dietary shift. © 2016 John Wiley & Sons Ltd.

    Full Text Available Rural extension is a complex practice that involves the provision of technical assistance and advisory services to farmers and other rural actors with the aim of improving agricultural production as well as organizational and commercial dynamics. Thus, it is clear that rural extension as an interdisciplinary practice that requires contributions from different social sciences. In consequence, it can be argued that psycholog y has a great potential to contribute to rural extension. Nonetheless, it has been mentioned that its contributions to the topic have been scarce. Aiming to understand the potential role of psychologists in the context of rural extension, a qualitative, exploratory-descriptive research was conducted. A total of 40 extensionists from the Argentine northeast provinces were interviewed. Interviews were recorded and latter analyzed following grounded theory’s guidelines and using Atlas Ti software. The findings allow concluding that most rural extensionists consider that psycholog y could contribute to their practice, but without being able to clarify its specificities. Additionally, exten-sionists highlight potential contributions in the area of group dynamics, conflict management and the understanding of farmers’ behavior.

    2009-04-01

    Full Text Available We present a statistical study of variations in the F2-layer peak electron density, NmF2, and altitude, hmF2, over the Argentine Islands ionosonde. The critical frequencies, foF2, and, foE, of the F2 and E-layers, and the propagation factor, M(3000F2, measured by the ionosonde during the 1957–1959 and 1962–1995 time periods were used in the statistical analysis to determine the values of NmF2 and hmF2. The probabilities to observe maximum and minimum values of NmF2 and hmF2 in a diurnal variation of the electron density are calculated. Our study shows that the main part of the maximum diurnal values of NmF2 is observed in a time sector close to midnight in November, December, January, and February exhibiting the anomalous diurnal variations of NmF2. Another anomalous feature of the diurnal variations of NmF2 exhibited during November, December, and January when the minimum diurnal value of NmF2 is mainly located close to the noon sector. These anomalous diurnal variations of NmF2 are found to be during both geomagnetically quiet and disturbed conditions. Anomalous features are not found in the diurnal variations of hmF2. The statistical study of the NmF2 winter anomaly phenomena over the Argentine Islands ionosonde was carried out. The variations in a maximum daytime value, R, of a ratio of a geomagnetically quiet daytime winter NmF2 to a geomagnetically quiet daytime summer NmF2 taken at a given UT and for approximately the same level of solar activity were studied. The conditional probability of the occurrence of R in an interval of R, the most frequent value of R, the mean expected value of R, and the conditional probability to observe the F2-region winter anomaly during a daytime period were calculated for low, moderate, and high solar activity. The calculations show that the mean expected value of R and the occurrence frequency of the F2-region winter anomaly increase with increasing solar activity.

    2008-01-01

    The preservation of primary information related to Radiological Protection and Nuclear Safety in the Argentine Nuclear Regulatory Authority began as a need of and as significant contribution to the future activities of the institution. Since 2005 a high number of experts have retired from the organization and will continue to do so until 2010. Besides, the primary information that experts possess is technical information produced at the beginning of Argentina's regulatory activity in the 50 's. If this information on account of its relevance - could not be preserved properly or be made available to the future generation of scientists and technicians, such an issue could have a negative impact on the efficiency and effectiveness of the institution in the future. The methodology selected for the project comprises several stages. Overall, the first stage consists in identifying primary information and expert's explicit knowledge through interviews and personal consultations. The second stage consists in converting to digital format the documentation that experts have traditionally kept in paper format. The third stage deals with transferring to a new database the already digitalized information from the computers of experts who are about to retire. The final stage is based on managing this information by creating knowledge maps and socio-grams, experts personal Web sites and a database with a mega browser to make information readily accessible. During the early months of the project, 190 pages have on average been converted to digital format on a daily basis, the equivalent of around 8 MB of information. The men/hours employed for this task has been around 40 minutes per day. As time went by, the method turned more efficient and as a result, some 400 pages were converted to digital format on a daily basis, accounting for 16 MB of information. The men/hours employed for this task has been around 60 minutes per day. Up until mid 2008, more than 1,000 documents have been

  8. [Argentine migration policy and movements of the European population (1876-1925)].

    Devoto, F J

    1989-04-01

    This work examines changes in Argentine migration policy from 1876-1925 and the relationship between public policy and population movements. Promoting immigration from Europe as proposed in article 25 of the Argentine constitution of 1853 was 1 of the most enduring objectives of Argentina's leadership. When Law of Immigration and Colonization (Law 817) was passed by the Chamber of Senators in 1876, the flow of immigration was at its lowest point in 8 years. Many of the provisions of Law 817 had already been put into practice occasionally or systematically, but the intent to use the law to attract a far greater number of immigrants and to select qualities seen as desirable were novel elements and the principal motives of the legislation. The unstated aim of reducing the preponderance of Italian immigration from about 2/3 was not immediately achieved. Argentina's immigration policy and actions were in competition with those of other Latin American countries and with the US. Information offices for prospective immigrants were opened in the 1880s in Paris, London, Brussels, Berlin, Vienna, Bern, and New York, and in 1887 legislation was passed permitting subsidized passages on a large scale. The continued predominance of Italian immigration demonstrated the limits of government policy influence, even when large sums of money were invested. The informal network of Italian immigrants already in Argentina and the activities of interested shipping companies on the other hand played major roles in maintaining Italian immigration. The total number of immigrants and the diversity of national origins were increased by the subsidized passages, but in 1891 the combination of a financial crisis and an end to subsidized passages decisively reduced the total flow. Changes occurred in the 1890s in regional flows within countries and in the occupational composition of immigrants from agricultors to day laborers, unskilled workers, and artisans. By about 1910 the conservative elements

    Since its creation in 1967, the Argentine Radiation Protection Society (SAR) promotes all the radiation protection and nuclear safety aspects not only within the scientific, technical and academic areas, but also to general public. To fulfill this objective, SAR organised training and refresher courses, seminars and workshops on RP subjects. During 2002, SAR organised 7 basic and specialized courses regarding the uses of radioactive materials in industrial applications and the course on medical response in radiological accidents, that was attended by Argentine and other Latin American participants. The programmes of the courses are developed in compliance with the legal requirements and also considering specifics needs. In this paper, the characteristics of the courses are enunciated and basic statistics regarding courses and participants are presented. For the 2003 and 2004, SAR foresees the organisation of 18 courses per year and has the capacity to deliver other courses by request. all the courses are delivered in Spanish language. Based on this educational experience SAR consider a priority the inclusion, of a RP module in all the scientific graduate programmes to generate awareness on the importance of RP. Taking into account the migration of professionals to Europe and North America and the Globalization, SAR advocates the harmonization of RP syllabus to attain an international recognition. (Author)

    Trophallaxis between individual worker ants and the toxicant load in dead and live Argentine ants (Linepithema humile) in colonies exposed to fipronil and hydramethylnon experimental baits were examined using accelerator mass spectrometry (AMS). About 50% of the content of the crop containing trace levels of {sup 14}C-sucrose, {sup 14}C-hydramethylnon, and {sup 14}C-fipronil was shared between single donor and recipient ants. Dead workers and queens contained significantly more hydramethylnon (122.7 and 22.4 amol/μg ant, respectively) than did live workers and queens (96.3 and 10.4 amol/μg ant, respectively). Dead workers had significantly more fipronil (420.3 amol/μg ant) than did live workers (208.5 amol/μg ant), but dead and live queens had equal fipronil levels (59.5 and 54.3 amol/μg ant, respectively). The distribution of fipronil differed within the bodies of dead and live queens; the highest amounts of fipronil were recovered in the thorax of dead queens whereas live queens had the highest levels in the head. Resurgence of polygynous ant colonies treated with hydramethylnon baits may be explained by queen survival resulting from sublethal doses due to a slowing of trophallaxis throughout the colony. Bait strategies and dose levels for controlling insect pests need to be based on the specific toxicant properties and trophic strategies for targeting the entire colony.

    Full text: In 1997 began in Argentine, sponsored by Nuclear Regulatory Authority (ARN) the intercomparison program for personal dosimetry laboratories, on a voluntary basis. Up to know 6 exercises have been done. The program began with a workshop to present the quantities, personal dose equivalent, Hp(10) and extremities dose equivalent, Hs(d). The first aim of this program was to know the true sate of personal dosimetry laboratories in the country, and then introduce the personal dose equivalent, Hp(10) into the dose measurements. The Regional Reference Center for Dosimetry (CCR), belonging to CNEA and the Physical Dosimetry Laboratory of ARN performed the irradiation. Those were done air free and on ICRU phantom, using x-ray, quality ISO: W60, W110 and W200; and 137 Cs and 60 Co gamma rays. The irradiation was made following ISO 4037 (2) recommendations. There are studied the dose, energy and angular response of the different measuring system. The range of the dose analyzed was from 0.2 mSv up to 80 mSv. The beam incidence was normal and also 20 o and 60 o . The dosimeters irradiation's were performed kerma in free in air and in phantom in order to study the availability of the service to evaluate the behavior as a function of kerma free in air or Hp(10). At the same time several items have been asked to each participant referring to the action range, the detectors characteristics, the laboratory procedures, the existence of an algorithm and its use for the dosimeter evaluation and the wish to participate in a quality assurance program. The program worked in writing a standard of personal dosimetry laboratories, that was published in 2001. In this work the results of each laboratory and its performance based on the ICRP-60 and ICRP-35 acceptance criteria are shown. Also the laboratory evolution and inquiry analyses have been included.

    Full Text Available This paper addresses the judicialization of end of life medical decision-making, as part of the advance of the justice system in the regulation of medical practice and the rise of recognition of patient autonomy. The article analyzes, from a sociological standpoint, legal decisions regarding treatment refusal at the end of life produced by the Argentine courts between 1975 and 2015. Based on a qualitative design, 38 sentences collected from jurisprudential databases using key terms were analyzed. First, judicialized cases during the period are described; these are characterized by a high proportion of claims presented by health institutions, a pro-treatment bias in the legal actions requested, and a high percentage of unnecessary litigation in the absence of conflicts or in situations that do not require court intervention. Second, legal and extralegal factors affecting the justiciability of decisions to refuse or withdraw medical treatments, such as changes in the law and processes of politicization of claims, are analyzed.

    In 1989, the US Department of Energy (DOE) established the Office of Environmental Management (EM) and delegated to the office the responsibility of cleaning up the US nuclear weapons complex. EM's mission has three primary activities: (1) to assess, remediate, and monitor contaminated sites and facilities; (2) to store, treat, and dispose of wastes from past and current operations; and (3) to develop and implement innovative technologies for environmental remediation. 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 industry 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. Florida International University's Hemispheric Center for Environmental Technology (FIU-HCET) serves as DOE-OST's primary technology transfer agent. FIU-HCET acts as the coordinating and managing body for the Department of Energy (DOE)-Argentina National Atomic Energy Commission (CNEA) Arrangement. Activities include implementing standard operating procedures, tracking various technical projects, hosting visiting scientists, advising DOE of potential joint projects based on previous studies, and demonstrating/transferring desired technology. HCET hosts and directs the annual Joint Coordinating Committee for Radioactive and Mixed Waste Management meeting between the DOE and CNEA representatives. Additionally, HCET is evaluating the possibility of establishing similar arrangements with other Latin American countries

    Prevention of vector-borne transmission of Chagas disease mainly relies on residual insecticide spraying. Despite significant success at a regional scale, house infestation with Triatoma infestans (Klug) (Hemiptera: Reduviidae) still persists in the Gran Chaco ecoregion. One key aspect is the identification of the sources of reinfestant triatomines. After detecting fine-scale genetic structure in two rural villages of Pampa del Indio, Argentine Chaco, we tested hypotheses on the putative origins of the triatomines collected at 4, 8, and 12 mo after insecticide house spraying. We genotyped 10 microsatellite loci in 262 baseline and 83 postspraying triatomines from different houses. Genetic variability was similar between baseline and postspraying populations, but 13 low-frequency alleles were not detected at postspraying. FSTs were not significant between insects collected before and after insecticide spraying at the same house in all but one case, and they clustered together in a neighbor-joining tree. A clustering algorithm detected seven genetic groups, four of them mainly composed of baseline and postspraying insects from the same house. Assignment tests suggested multiple putative sources (including the house of collection) for most postspraying insects but excluded a house located more than 9 km from the study area. The origin of three triatomines was attributed to immigration from other unaccounted sources. Our study is compatible with the hypothesis that house reinfestations in the Argentine Chaco are mostly related to residual foci (i.e., survival of insects within the same community), in agreement with field observations, spatial analysis, and morphometric studies previously published.

    Full Text Available Latin American legislatures have gone largely unstudied, with the functioning of the Argentine Chamber of Deputies prior to the 1980s being an entirely unexplored subject. This paper fills that gap by examining the organization of the Chamber, with particular focus on its standing committee system from 1946 to 2001. We assess the portability of two U.S.-based theoretical approaches to legislative organization by applying them to committee assignments. An original data set of Argentine deputies was constructed and a way of measuring political power in committees was devised for this study. Despite weak democratic governments, military interventions, and changes to the electoral system, we find that ruling parties have consistently influenced the committee system, shaping its structure and securing an over-proportion of their deputies in key committee positions. These results support the applicability of the U.S. originated Cartel Theory of legislative organization to understanding and studying legislatures outside that country.Las legislaturas latinoamericanas no han recibido debida atención. Un caso emblemático es la Cámara de Diputados Argentina, cuyo funcionamiento previo a los 1980’s ha sido inexplorado. Este artículo persigue llenar ese vacío examinando la organización de su sistema de comisiones permanentes desde 1946 hasta 2001. Para ello, evaluamos la aplicabilidad de dos teorías norteamericanas sobre organización legislativa para analizar la integración de comisiones, creamos una base de datos de diputados argentinos y diseñamos una forma de medir su poder político en las comisiones. A pesar de la inestabilidad institucional y los cambios de sistema electoral, los resultados demuestran que los partidos que controlaron la Cámara influenciaron en forma sistemática el sistema de comisiones, cambiando su estructura y asegurando la sobrerrepresentación de sus diputados en cargos clave.

    Full Text Available This article examines the recent behaviour in Argentina of two national protest groups of socalled ‘piqueteros’ or picketers (impoverished unemployed individuals who used the blockage of strategic roads and bridges to force government concessions that emerged politically in the buildup to the crisis of 2001-2002. Using theoretical concepts developed by McAdam, Tarrow, and Tilly in understanding social movements, the author analyses what he calls the ‘survival strategy’ adopted by their leaders as the political opportunities that produced their initial growth gave way to a more hostile environment with the normalization of Argentine politics under the Kirchner administration. While the two piquetero groups studied differ considerably in terms of their politics and ideology, both ended up depending on the same traditional tactic of utilizing important government contacts to obtain the resources necessary for organizational maintenance, despite their nominal identity as radical protesters against the present political system.Resumen: Perpetuando movimientos sociales y oportunidades decrecientes: las estrategias de sobrevivencia de dos grupos de piqueteros argentinesEste artículo examina el comportamiento reciente de dos grupos nacionales de protesta argentinos llamados ‘piqueteros’ (desempleados empobrecidos que usaron el bloqueo de calles y puentes estratégicos para forzar concesiones gubernamentales que aparecieron durante la crisis de 2001- 2002.

    Full Text Available Cet article propose une approche de quelques archétypes qui, jusqu’en Europe, ont contribué à construire une image un peu théâtrale et parfois floue de l’Argentin. Une image littéraire avant tout, mais paradoxalement, souvent proche de la réalité socioculturelle car l’identité du romancier latino-américain est souvent liée à un profond engagement qui se traduit par la description et l’analyse – philosophique, politique, historique, sociologique… - du réel. C’est en étudiant le portrait que les intellectuels du XIXème siècle dressent du gaucho, personnage emblématiquement fort mais aussi victime de toutes les manipulations idéologiques, que l’on voit comment l’identité argentine a été forgée autour d’une dichotomie civilisation-barbarie dont le mythe semble encore vivant dans l’Argentine d’aujourd’hui. L’article aborde ensuite le thème de l’immigration, facteur essentiel de la mutation de cette société et de son entrée dans le XXème siècle. Le portrait de l’Argentin de classe moyenne (groupe social qui distingue particulièrement l’Argentine du reste de l’Amérique latine est ensuite dessiné plus en détail, mais à travers le miroir à la fois déformant et grossissant de l’écrivain Manuel Puig. Il est indéniable que l’imaginaire modèle la réalité. La littérature est certes un miroir déformant et contradictoire de la réalité mais elle appartient aussi à cette réalité.This paper focuses on some of the archetypes which have contributed to the construction of the rather theatrical and blurred picture of the Argentinian – including in Europe.

    The Brazilian-Argentine Agency (ABACC) and the 'Common System of Accounting and Control of Nuclear Materials' (SCCC) are the result of a process started with nuclear cooperation between Argentina and Brazil. The SCCC reflects a common policy of transparency established by a Bilateral Agreement. Its insertion in the global context was made through a Quadripartite Agreement (Argentina, Brazil, ABBAC, IAEA). This paper describes the role of the State System of Accounting and Control (SSAC) in the framework established in the Bilateral and the Quadripartite Safeguards Agreements and in the context of new trends and perspectives in international safeguards. It could also serve as a example for initiatives in other regions. (author)

    Full Text Available Carbamoyl phosphate synthetase 1 ( CPS1 is a key gene in the first step of urea cycle and has been correlated with nitric oxide level and vascular smooth muscle activity. A functional single-nucleotide polymorphism C/A at position 4217 in CPS1 (National Center for Biotechnology Information SNP database no. rs7422339, T1405N was reported to be associated with high homocysteine (Hcy plasma values. Although genetic variants of methylenetetrahydrofolate reductase ( MTHFR gene are known to influence Hcy concentration, other genetic determinants of Hcy remain largely unknown. The association between the CPS1 rs7422339 and the risk of hyperhomocysteinemia in Latin American populations is unknown. Here, we study this association in 100 patients having hyperhomocysteinemia without MTHFR c.677C>T polymorphism and 100 controls. CPS1 rs7422339 was studied using polymerase chain reaction and enzymatic restriction. Comparisons of the CPS1 rs7422339 genotype distributions revealed a significant difference between groups ( P = 2.3 × 10 −3 . Patients carrying polymorphic allele showed almost 3 times higher risk (odds ratio [OR] = 2.47 of hyperhomocysteinemia than wild-type allele, suggesting that rs7422339 SNP is associated with high Hcy levels in the Argentine population.

    In order to establish a correlation between the different types of soils using hyperfine and magnetic parameters as climatic and environmental proxies, we have studied the differentiation of soil developed around 38.5 o south latitude, in the central Pampas of Argentina, by means of Moessbauer spectroscopy and environmental magnetism. The soils transect (climosequence) investigated stretches from the drier west (around 64 o W) to the more humid east (at around 59 o W) in the Buenos Aires Province, covering a distance of 600 km. The soils studied developed during recent Holocene geologic times in a landscape characterized by small relict plateaus, slopes and depressions, dunes and prairies. The parent material consists of eolian sandy silts overlying calcrete layers. The low mean annual precipitation in the western parts of the region gives rise to soils without B-horizons, which limits the agricultural use of land. The preliminary results show an increase of the paramagnetic Fe 3+ relative concentration from west to east in the soils investigated. Magnetite is probably mainly responsible for the observed enhancement in the susceptibility values. The magnetic response of the parent material is similar to that of the loess part of the previously investigated loess-paleosol sequences of the Argentine loess plateau.

    Control of fungal plant diseases by using naturally occurring non-pathogenic microorganisms represents a promising approach to biocontrol agents. This study reports the isolation, characterization, and fungal antagonistic activity of actinobacteria from forage soils in the Flooding Pampa, Argentina. A total of 32 saprophytic strains of actinobacteria were obtained by different isolation methods from rhizospheric soil of Lotus tenuis growing in the Salado River Basin. Based on physiological traits, eight isolates were selected for their biocontrol-related activities such as production of lytic extracellular enzymes, siderophores, hydrogen cyanide (HCN), and antagonistic activity against Cercospora sojina, Macrophomia phaseolina, Phomopsis sp., Fusarium oxysporum, and Fusarium verticilloides. These actinobacteria strains were characterized morphologically, physiologically, and identified by using molecular techniques. The characterization of biocontrol-related activities in vitro showed positive results for exoprotease, phospholipase, fungal growth inhibition, and siderophore production. However, none of the strains was positive for the production of hydrogen cyanide (HCN). Streptomyces sp. MM140 presented the highest index for biocontrol, and appear to be promising pathogenic fungi biocontrol agents. These results show the potential capacity of actinobacteria isolated from forage soils in the Argentine Pampas lowlands as promising biocontrol agents, and their future agronomic applications. © 2016 WILEY-VCH Verlag GmbH & Co.

    Relative concentrations of nickel and copper at the surface of the ring and centre parts of 1-peso and 2-pesos Argentine coins have been studied by means of X-ray photoemission spectroscopy (XPS). It has been observed Ni-enrichment at the surface of the ring (silvery) part of a 1-peso, minted in 1994, whereas the XPS data reveals lack of nickel at the surface of the centre (silvery) part of a 2-pesos, minted in 2016. This discrepancy is explained by analyzing the XPS peaks of oxygen and carbon, and is suggested to be related to the contamination layer on the surface of the coins. The XPS analysis of the golden parts of the coins, namely the centre part of the 1-peso and the ring part of the 2-pesos coins were inconclusive, due to the small amount of the Ni (nominally %2) used in those parts. The possible oxidations states of the metals at the surface of the untreated and treated coins with the artificial human sweat were also identified.

    Argentina has given recently a new start to its nuclear power activities. Looking for background and experiences that can be useful under the new reality, the paper is a survey of the past development of local suppliers for the national nuclear industry. Based on the intention to answer the questions: Why so early it was decided to build a nuclear power plant? Why it was decided to buy it under a turnkey basis rather than developing an indigenous design? and what was the meaning of the 'opening of the technology package' at that time?, the paper describes the actions that led to the purchase of the Atucha I, Embalse and Atucha II nuclear power plants and how these decisions were implemented in order to maximize local participation and the technology transfer. It also analyzes the influence of the Argentine Nuclear Plan of the late seventies on the development of endogenous technology and describes the facts that helped to preserve until now the technological nuclear capabilities of the country in spite of the stopping of the Atucha II construction, and to create positive expectations regarding the revival of the local industry as a supplier of nuclear goods and services.

    Full Text Available The software sector is of growing importance and, due to its degree of dynamism, the identification of capabilities for innovation is vital. This study identifies capabilities variables that distinguish Argentine software companies with high innovation results and high innovation impacts from those with lesser results and impacts. It is applied to a sample of 103 companies, a measurement model and the component variables of an innovation degree index for software companies (INIs formulated in previous studies. A Principal Component Analysis and a biplot are conducted. In the analysis of results and impacts, 100% of the variability within the first two components is explained, which shows the high correlation between variables. From the biplots, it appears that companies with high results have higher degrees in the variables of motivation, strategy, leadership and internal determinants; and those with high impacts present higher degrees of structure, strategy, leadership, free software and innovation activities. The findings add elements to the theory of capabilities for innovation in the software sector and allow us to consider the relative importance of different capabilities variables in the generation of innovation results and impacts.

    Full Text Available Since the end of the last Argentine Dictatorship (1976-1983, a number of feature-length films have engaged in the public debate over the legacies of state terrorism. El secreto de sus ojos (2009, Argentina's most recent Oscar winner, is the latest to do so, exploring the effects of more than a decade of impunity on those who lost their loved ones. Suggesting that restoration of a justice system that works can lead to the restoration of full civic engagement in a healthy body politic, the film raises important questions about citizenship and belonging in a post-national era. This essay explores the film's phenomenal success in the global memory market to illuminate what remains at stake in contemporary narratives of reconciliation.

    This paper is a review of the current status about the remaining problems that are found in the investigation of the Quaternary Argentine soils and loessic sediments, and the way that Moessbauer studies can assist in solving them. There are two main types of investigations that make use of the magnetic response of the samples to correlate them with information gathered by other methods. On the one hand, there is the stratigraphic and chronological research, which is of importance from the geological and paleontological points of view. On the other hand, the paleoclimatic records, of significance toward a possible model of the past climate, are also studied because of their close relation to the sediments history. However, there is not yet a model that can tell the difference between the modifications due to the climatic conditions at the time when the soils were buried from processes that occurred after burial. Some examples are given that show that Moessbauer studies can be applied with a certain degree of success when cross-checked with magnetic measurements toward understanding the processes that occurred in alluvial B (paleosols) and C horizons (loess) from the eastern part of Buenos Aires Province. Although the application of Moessbauer studies to hydromorphic processes in soils is not straightforward, there are cases in which Moessbauer spectroscopy, if applied properly and correlated with other techniques, is able to characterize the type of iron oxides existing in the materials and thus assist theories about its origin and history.

    Teaching and the training are indispensable for the development of the human resources in all disciplines and occupations of the man in the world scale. About the applications of the radionuclides in the nuclear industry, in Argentina, during the last years, the efforts have been intensified. The necessity of improving the capacity of answer in radiation protection and nuclear safety demands an focus integrated in the teaching and the training. The radiological protection and the nuclear safety presents elements of the applied physics, the chemistry, the biology, the nuclear technology and other specialized subjects. However, in relation with the development of the human resources, specially those that belong to regulatory bodies and perform inspection functions, have important differences, necessities and specific problems. Some differences and problems emerge of the wide diversity and reach of the radiological and nuclear applications. Nowadays, in the world, the applications of the radiation and radioactive sources are being diversified in the medicine (diagnosis, radiotherapy, nuclear medicine, the industry, the agricultures, and the investigation and teaching), that involve a permanent knowledge and actualization of the personnel of the regulatory bodies. For that exposed this work describe training program for the personnel with regulatory functions (inspectors) of the Nuclear Regulatory Authority in the Argentine Republic.

  19. Loss of Wolbachia infection during colonisation in the invasive Argentine ant Linepithema humile.

    2005-03-01

    WOLBACHIA are maternally inherited bacteria, which are very common in arthropods and nematodes. Wolbachia infection may affect host reproduction through feminisation, parthenogenesis, male-killing, cytoplasmic incompatibility and increased fecundity. Previous studies showing discrepancies between the phylogenies of Wolbachia and its arthropod hosts indicate that infection is frequently lost, but the causes of symbiont extinction have so far remained elusive. Here, we report data showing that colonisation of new habitats is a possible mechanism leading to the loss of infection. The presence and prevalence of Wolbachia were studied in three native and eight introduced populations of the Argentine ant Linepithema humile. The screening shows that the symbiont is common in the three native L. humile populations analysed. In contrast, Wolbachia was detected in only one of the introduced populations. The loss of infection associated with colonisation of new habitats may result from drift (founder effect) or altered selection pressures in the new habitat. Furthermore, a molecular phylogeny based on sequences of the Wolbachia wsp gene indicates that L. humile has been infected by a single strain. Horizontal transmission of the symbiont may be important in ants as suggested by the sequence similarity of strains in the three genera Linepithema, Acromyrmex, and Solenopsis native from South and Central America.

    The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document 'Education and

    We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spatial positions in the experimental arena and at different times. Then we derived the response function of individual ants to pheromone concentrations by looking at correlations between concentrations and changes in speed or direction of the ants. Ants were found to turn in response to local pheromone concentrations, while their speed was largely unaffected by these concentrations. Ants did not integrate pheromone concentrations over time, with the concentration of pheromone in a 1 cm radius in front of the ant determining the turning angle. The response to pheromone was found to follow a Weber's Law, such that the difference between quantities of pheromone on the two sides of the ant divided by their sum determines the magnitude of the turning angle. This proportional response is in apparent contradiction with the well-established non-linear choice function used in the literature to model the results of binary bridge experiments in ant colonies (Deneubourg et al. 1990). However, agent based simulations implementing the Weber's Law response function led to the formation of trails and reproduced results reported in the literature. We show analytically that a sigmoidal response, analogous to that in the classical Deneubourg model for collective decision making, can be derived from the individual Weber-type response to pheromone concentrations that we have established in our experiments when directional noise around the preferred direction of movement of the ants is assumed.

We discuss this through the study of the documentary film Following Indian Trails by the Pilcomayo River, which was recorded during a Swedish expedition to the Argentine Chaco in 1920 and later released in Stockholm in 1950 during a private screening organized by the Swedish Chaco Travellers Association. We argue that the film presents an account inspired by classic ethnography which rescues and puts into circulation images of indigenous people from the “impenetrable” and “savage” Chaco. The ethnographic emphasis in the narrative seems to have shifted with time as it was probably only partly present during the shooting of the footage. In the narrative mode of “monstration,” when bodies meet machines “in the field,” native performances are presented as an “unstaged” and realist spectacle. Later in the 1950 macro-“narration,” encompassing the final cutting and editing of the original footage, fragments of spectacle are systematized into an ethnographic description of primitive life.

    To obtain a psychomotor development index (PDI) for each Argentine province. Using a national, probabilistic, and stratified sample of 13 323 male and female children younger than 6 years selected for the National Survey on Nutrition and Health (Encuesta Nacional de Nutrición y Salud, ENNyS 2004), we estimated the PDI per province based on compliance with 10 developmental milestones. The median age at attainment (median age) of each milestone was estimated adjusting a logistic regression. The PDI was estimated as 100* (1 + b), where "b" is the regression coefficient of y= a + b x, where "y" is the median age as per the national reference (x) minus the median age at attainment of a milestone. The theoretical value expected for the PDI was 100. The PDI per province ranged between 72.1 and 106.4. Most provinces showed a negative regression coefficient, which indicated a progressive increase of the delay in the age at attainment of milestones. The correlation coefficient between the PDI per province and infant mortality in 2005was extremely high: -0.85, suggesting that both indicators share similar biological and social determinants. The PDI was negative because the higher the mortality, the lower the PDI. We have now a positive health indicator available in Argentina: the psychomotor development index, which is a low-cost, easy to collect, and reliable tool that may be used in national health statistics.

    Ezequiel Mabragaña

    Full Text Available BACKGROUND: DNA barcoding has been advanced as a promising tool to aid species identification and discovery through the use of short, standardized gene targets. Despite extensive taxonomic studies, for a variety of reasons the identification of fishes can be problematic, even for experts. DNA barcoding is proving to be a useful tool in this context. However, its broad application is impeded by the need to construct a comprehensive reference sequence library for all fish species. Here, we make a regional contribution to this grand challenge by calibrating the species discrimination efficiency of barcoding among 125 Argentine fish species, representing nearly one third of the known fauna, and examine the utility of these data to address several key taxonomic uncertainties pertaining to species in this region. METHODOLOGY/PRINCIPAL FINDINGS: Specimens were collected and morphologically identified during crusies conducted between 2005 and 2008. The standard BARCODE fragment of COI was amplified and bi-directionally sequenced from 577 specimens (mean of 5 specimens/species, and all specimens and sequence data were archived and interrogated using analytical tools available on the Barcode of Life Data System (BOLD; www.barcodinglife.org. Nearly all species exhibited discrete clusters of closely related haplogroups which permitted the discrimination of 95% of the species (i.e. 119/125 examined while cases of shared haplotypes were detected among just three species-pairs. Notably, barcoding aided the identification of a new species of skate, Dipturus argentinensis, permitted the recognition of Genypterus brasiliensis as a valid species and questions the generic assignment of Paralichthys isosceles. CONCLUSIONS/SIGNIFICANCE: This study constitutes a significant contribution to the global barcode reference sequence library for fishes and demonstrates the utility of barcoding for regional species identification.

    Pectinolytic enzymes are greatly important in winemaking due to their ability to degrade pectic polymers from grape, contributing to enhance process efficiency and wine quality. This study aimed to analyze the occurrence of pectinolytic yeasts during spontaneous fermentation of Argentine Bonarda grape, to select yeasts that produce extracellular pectinases and to characterize their pectinolytic activity under wine-like conditions. Isolated yeasts were grouped using PCR-DGGE and identified by partial sequencing of 26S rRNA gene. Isolates comprised 7 genera, with Aureobasidium pullulans as the most predominant pectinolytic species, followed by Rhodotorula dairenensis and Cryptococcus saitoi. No pectinolytic activity was detected among ascomycetous yeasts isolated on grapes and during fermentation, suggesting a low occurrence of pectinolytic yeast species in wine fermentation ecosystem. This is the first study reporting R. dairenensis and Cr. saitoi species with pectinolytic activity. R. dairenensis GM-15 produced pectinases that proved to be highly active at grape pH, at 12 °C, and under ethanol and SO2 concentrations usually found in vinifications (pectinase activity around 1.1 U/mL). This strain also produced cellulase activity at 12 °C and pH 3.5, but did not produce β-glucosidase activity under these conditions. The strain showed encouraging enological properties for its potential use in low-temperature winemaking. PMID:26413065

Methods: Data from the 2007 Argentina Global School-based Student Health Survey (GSHS, a nationally representative survey of middle school students, were examined using age-adjusted logistic regression models. Results: Of the 1,328 participating students aged 13 to 15 years old, 51.9% reported drinking alcohol in the previous month, with higher rates among males (p = 0.04 and older students (p < 0.01. Both male and female drinkers were nearly twice as likely as non-drinkers to report being physically attacked, being in a physical fight, and having thoughts about self-directed violence. Among drinkers, those who reported poor mental health, were victims of bullying, used tobacco or drugs, or skipped school without per- mission were approximately twice as likely as other drinkers to have engaged in violent activities. Conclusion: Public health interventions targeting violence among young adolescents should be developed in combination with alcohol education programs.

    Full Text Available We propose to analyze the acting in cinema and theater of the argentine democratic return, in order to highlight its political dimension implied. Thanks to the willingness to represent the recent past, acting in films will be limited to the realism. But at the same time, new expressions of young artists based in the irruption of the body and sexuality emerged in the theater. We believe that this aggressive deployment of a revulsive, offset and young corporality, constituted a vital affirmation before the horror of the dictatorship. In addition, these experiences reacted to the imposition of an acting performance at the service of transmission of a message, imaginary of "productive body" present in realism, but also in groups militants of the 70s.

    The Argentine broken foreland has been the subject of continuous research to determine the uplift and exhumation history of the region. High-elevation mountains are the result of N-S reverse faults that disrupted a W-E Miocene Andean foreland basin. In the Sierra de Ambato (northern Argentine broken foreland) the reverse faults offset Neogene sedimentary rocks (Aconquija Fm., ˜9 Ma) and affect the basement comprising Paleozoic metamorphic rocks that have been dated at ˜477-470 Ma. In order to establish a chronology of these faults affecting the previous continuous basin we date the formation age of clay minerals associated with fault gouge using the K-Ar dating technique. Clay mineral formation is a fundamental process in the evolution of faults under the brittle regime (history with a minimum age of ˜360 Ma and a last clay minerals forming event at ˜220 Ma. Moreover, given the progression of apparent ages decreasing from coarse to fine size fractions (˜360-311 Ma for 2-1 μm grain size fraction, ˜326-286 Ma for 1-0.2 μm and ˜291-219 Ma of <0.2 μm), we modeled discrete deformation events at ˜417 Ma (ending of the Famatinian cycle), ˜317-326 Ma (end of Gondwanic orogeny), and ˜194-279 Ma (Early Permian - Jurassic deformation). According to our data, the Neogene reactivation would not have affected the K-Ar system neither generated a significant clay minerals crystallization in the fault gouge, although an exhumation of more than 2 Km is recorded in this period from stratigraphic data.

    In Argentine, comprehensive noise measurements have been performed with the reactor instrumentation of the PHWR power plant Atucha I and Embalse. The Embalse reactor is a CANDU-600 (600 Mwe) type pressurized heavy water reactor. It's a heavy water moderator and heavy water cooled natural uranium fueled pressure tube system. Signal of vanadium and platinum type in core-self power neutron detectors of ex-core ion chambers and of a moderator pressure sensor have been recorded and analysed. The vibration of reactor internals as vertical and horizontal in-core neutron flux detectors units and the coolant channels systems, consisting of calandria and pressure tubes with fuel bundles, have been identified and monitored during normal reactor operation. Atucha I, is a PHWR reactor natural uranium fueled, and heavy water moderated and cooled. Neutron noise techniques using of ex-core ionization chambers and in-core Vanadium SPND's were implemented, among others, in order to produce early detection of anomalous vibrations in the reactor internals. Noise analysis was successfully performed to identify normal and peculiar vibrations in particular reactor internals. (author)

    The second exon of equine leucocyte antigen (ELA)-DQB genes was amplified from genomic DNA of 32 Argentine Creole horses by PCR. Amplified DNA was analysed by PCR-restriction fragment length polymorphism (RFLP) and PCR-single-strand conformation polymorphism (SSCP). The PCR-RFLP analysis revealed two HaeIII patterns, four RsaI patterns, five MspI patterns and two HinfI patterns. EcoRI showed no variation in the analysed sample. Additional patterns that did not account for known exon 2 DNA sequences were observed, suggesting the existence of novel ELA-DQB alleles. PCR-SSCP analysis exhibited seven different band patterns, and the number of bands per animal ranged from four to nine. Both methods indicated that at least two DQB genes are present. The presence of more than two alleles in each animal showed that the primers employed in this work are not specific for a unique DQB locus. The improvement of this PCR-RFLP method should provide a simple and rapid technique for an accurate definition of ELA-DQB typing in horses.

    Bifenthrin, chlorfenapyr, fipronil, and thiamethoxam were evaluated for activity against the Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae). Mobility impairment and lethal times were determined after topical treatments. Ants were immobilized most quickly by bifenthrin, followed by chlorfenapyr and thiamethoxam. After 2 h, the number of fipronil-treated ants unable to walk out of test arenas did not differ from control ants. Median lethal time (LT50) after topical treatment was lowest in the bifenthrin treatment, followed by thiamethoxam, chlorfenapyr, and then fipronil. Mortality due to horizontal exposure was evaluated at 10, 20, or 30 degrees C, with topically treated ant corpses serving as donors. There was low to moderate horizontal activity in bifenthrin and chlorfenapyr treatments, with no temperature effect in bifenthrin treatments and a positive temperature effect in chlorfenapyr treatments. Mortality in the fipronil treatments was highest and was positively correlated with temperature. Thiamethoxam treatments did not differ from controls at 10 degrees C, but mortality increased with temperature. To evaluate contact activity, either all of 20% of the ants in a cohort were exposed to insecticide-treated pine needles. In both tests, mortality was highest in fipronil and bifenthrin treatments, followed by thiamethoxam, with lowest mortality in chlorfenapyr treatments. Effectiveness as a barrier was evaluated by providing a choice between bridges treated with insecticide or water. Although bifenthrin did not provide an impenetrable barrier, it was the only treatment having fewer ants than its paired control. Mortality data suggest that lack of recruitment rather than repellency account for this result.

    Full Text Available Abstract Background The occurrence of variations in the spectrum of cardiovascular disease between different regions of the world and ethnic groups have been the subject of great interest. This study report the 24-h variation of myocardial infarction (MI occurrence in patients recruited from CCU located in Argentina and Uruguay. Methods A cohort of 1063 patients admitted to the CCU within 24 h of the onset of symptoms of an acute MI was examined. MI incidence along the day was computed in 1 h-intervals. Results A minimal MI incidence between 03:00 and 07:00 h and the occurrence of a first maximum between 08:00 and 12:00 h and a second maximum between 15:00 and 22:00 h were verified. The best fit curve was a 24 h cosinor (acrophase ~ 19:00 h, accounting for 63 % of variance together with a symmetrical gaussian bell (maximum at ~ 10:00 h, accounting for 37 % of variance. A similar picture was observed for MI frequencies among different excluding subgroups (older or younger than 70 years; with or without previous symptoms; diabetics or non diabetics; Q wave- or non-Q wave-type MI; anterior or inferior MI location. Proportion between cosinor and gaussian probabilities was maintained among most subgroups except for older patients who had more MI at the afternoon and patients with previous symptoms who were equally distributed among the morning and afternoon maxima. Conclusion The results support the existence of two maxima (at morning and afternoon hours in MI incidence in the Argentine and Uruguayan population.

    Although memories about a nation's past usually are semantic in nature, a distinction needs to be made between lived and distant semantic collective memories. The former refers to memories of community-relevant events occurring during the lifetime of the rememberer, whereas the latter to memories of distant events. Does the content of lived and distant semantic collective memories differ? Employing both free and cued recall, we examined the memories of younger and older Argentines of the Military Junta of 1976. We also examined the effects of political ideology. Content analysis indicated that (1) lived semantic collective memories were more likely to contain personal recollections than distant semantic collective memories, even though those with distant semantic collective memories could have incorporated memories of the parent's personal experience in their recollections, (2) lived semantic collective memories contained more causal statements, and (3) those on the Right with distant semantic collective memories were more likely to claim that they "Don't know" or offer positive accounts of the Junta, suggesting a need to "defend" the reputation of those on the Right. The results are discussed in terms of the goals and plans different generations might have when recollecting their nation's past.

  2. Large-Scale Agricultural Management and Soil Meso- and Macrofauna Conservation in the Argentine Pampas

    Full Text Available Soil is the most basic resource for sustainable agricultural production; it promotes water quality, is a key component of the biogeochemical cycles and hosts a huge diversity of organisms. However, we are not paying enough attention to soil degradation produced by land use. Modern agriculture has been successful in increasing yields but has also caused extensive environmental damage, particularly soil degradation. In the Argentine Pampas, agriculturization reached a peak with the generalized use of the no-till technological package: genetically modified soybeans tolerant to glyphosate, no-till, glyphosate, and inorganic fertilizers. This phenomenon has been widely spread in the country; the no-till package has been applied in large areas and has been used by tenants in a 60%–70% of cultivated lands. Thus, those who were involved in developing management practices may not be the same as those who will face degradation issues related to those practices. Indeed, most evidence reviewed in this paper suggests that the most widely distributed practices in the Pampas region are actually producing severe soil degradation. Biological degradation is particularly important because soil biota is involved in numerous soil processes on which soil functioning relies, affecting soil fertility and productivity. For example, soil meso- and macrofauna are especially important in nutrient cycling and in soil structure formation and maintenance, and they are key components of the network that links microbial process to the scale of fields and landscapes where ecosystem services are produced. However, the knowledge of the impact of different agricultural managements on soil meso- and macrofauna in Pampas agroecosystems is far from conclusive at this stage. The reason for this lack of definite conclusions is that this area has been given less attention than in other parts of the world; the response of soil fauna to agricultural practices is complex and taxa

    This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

    The present work reports the first data set on particulate organic carbon (POC) and nitrogen (PON), and the high-resolution modelling of their stable isotope variability in the Patagonian Cold Estuarine System (PCES), with focus on particulate organic matter (POM) origin and distribution in dependence on physical, chemical and biological parameters. POC, PON, stable carbon (δ13C) and nitrogen isotopes (δ15N), dissolved organic nitrogen, phaeopigments, diatom, dinoflagellate and heterotrophic bacteria (HB) abundance are reported for 17 stations in different waters masses in the southern end of the Argentine shelf in late summer 2012. Most parameters denote clear differences between Beagle - Magellan Water (BMW), Subantarctic Shelf Water (SSW) and Subantarctic Water (SAW). POC and PON decreased from maxima in BMW to intermediate values in SSW and minima in SAW. There was a highly significant correlation among POC, PON and fluorescence indicators of diagenetic maturity of dissolved humic matter. This, together with the inverse correlations of salinity with POC and PON, and the wide range of C:N ratios indicate that POM in the study area is partly derived from terrestrial runoff, superimposed by autochthonous components from plankton of different life stages. HB abundance was significantly correlated with POC and dissolved organic matter (DOM), likely reflecting a resource control of HB and a significant contribution of bacterial biomass to POM in the nanoparticle fraction. The direct relationship between HB and dissolved humics suggests bacterial uptake of DOM fractions otherwise considered refractory. POM complexity was reflected in a wide variation of δ13C, despite the narrow temperature range of this region. The variability of stable isotopes of POC could be accounted for by a model with a degree of detail hitherto not reported in the literature.

    The nutritional value of wild underexploited vegetable samples collected in the Argentine Chaco was investigated. Leaves from Hipochaeris sp.-, Coronopus didimus and Portulaca olearacea; fruits from Zyziphus sativa, Brumelia obtusifolia and Eugenia uniflora; and roots of Canna coccinea were included in this work; several separate samples being taken at least during two consecutive harvesting seasons. Values for moisture, protein, total lipids, crude fiber, ash, reducing and total sugars, starch, total pectins and energy are given. Mineral micronutrient contents are reported for calcium, potassium, magnesium, iron and phosphorus, as well as vitamin values (ascorbic acid and beta-carotene). Higher concentrations of macronutrients were found in the leafy vegetables (32-50 Kcal/100 g) than in commercially exploited cultivars (14-30 Kcal/100 g), as shown by an increased energy value, the protein content of Portulaca olearacea (3.74 g/100 g) being highly remarkable. Unusually high micronutrient figures were also determined in Coronopus didimus, with 172.3; 3.98, and 46.7 mg/100 g, for calcium, iron and magnesium, respectively. In general, fruits also showed higher macronutrient contents, with the exception of proteins, with less but constant values (1.58 to 1.74 g/100 g), although contributing more energy than commercial cultivars (70 to 147 Kcal/100 g). Equally important proved to be the provitamin A content in Eugenia uniflora (11.98 mg/100 g). Roots of Canna coccinea revealed the lowest energy value (34 Kcal/100 g) but surprisingly, the highest content of phosphorus of all the species under study.

    A new cestode, Echinobothrium notoguidoi n. sp., is described from the spiral intestine of the shark Mustelus schmitti, from coastal waters off Mar del Plata, Argentina. This species is distinguished from all others in the genus by a rostellar armature consisting of 2 apical groups of 31 large hooks each, arranged in 2 rows (16 anterior, 15 posterior) with 13 hooklets per side, a wide corona of 8-11 rows of spines posterior to the rostellum, 8 rows of 24-26 spines on the cephalic peduncle, and 11-15 testes per proglottid. The new species most closely resembles 2 congeners that also parasitize sharks, Echinobothrium musteli and Echinobothrium scoliodoni, on the basis of the armature of the rostellum and cephalic peduncle and the presence of a corona of small spines. Echinobothrium notoguidoi can be differentiated from E. musteli by the number of hooklets (3) and testes (22), and from E. scoliodoni by the number of large hooks (10-13), spines on the cephalic peduncle (> 100), and segments (40-50). Echinobothrium notoguidoi is clearly distinguished from Echinobothrium pigmentatum described previously from Zapteryx brevirostris in Argentine waters by the following combination of characters: corona of hooks lacking, possession of fewer apical hooks (20), hooklets in a continuous row instead of separate groups, fewer spines in the cephalic peduncle (9-13 per row), and fewer testes (5-7) per proglottid.

    The International Organization for Standardization (ISO) has more than 200 Technical Committees that develop technical standards. During April 2004 took place in Buenos Aires the 14th Plenary of the ISO/TC 85 Nuclear Energy Committee. During this Plenary issues as Nuclear Terminology, Radiation Protection, Nuclear Fuels, Nuclear Reactors and Irradiation Dosimetry was dealt with. 105 International delegates and 45 National delegates (belonging to CNEA, ARN, NASA, INVAP, CONUAR, IONICS and other organizations) attended the meetings. During this meeting ISO/TC 85 changed its scope; the new scope of the Committee is 'Standardization in the fields of peaceful applications of nuclear energy and of the protection of individuals against all sources of ionizing radiations'. This work summarizes the most important advances and resolutions about the development of standards taken during this meeting as well as the main conclusions. (author) [es

The multisite survey and NT trials permitted coverage of the history of the 140 years with agriculture. The decrease in SOC and SON storage that occurred during the first twenty years by a loss through biological activity was 27% for SOC and 32% for SON. The calibrated model described the SOC storage evolution very well and permitted an accurate simultaneous estimation of their three parameters. The validated model simulated well SOC and SON evolution. Overall, the results analyzed separately for the T and NT period indicated that the active pool has a rapid turnover (MRT ~9 and 13 years, resp. which represents 50% of SOC in the native prairie soil and 20% of SOC at equilibrium after NT period. NT implementation on soils with the highest soil organic matter reserves will continue to decrease (17% for three decades later under current annual addition.

    The irradiation of the first Argentine prototypes of pressurized heavy water reactor (PHWR) (U,Pu)O 2 MOX fuels began in 1986. These experiments were carried out in the High Flux Reactor (HFR)-Petten, Holland. The rods were prepared and controlled in the C NEA's α Facility. The postirradiation examinations were performed in the Kernforschungszentrum, Karlsruhe, Germany and in the Joint Research Center (JRC), Petten. The first rod has been used for destructive pre-irradiation analysis. The second one as a pathfinder to adjust systems in the HFR. Two additional rods including iodine doped pellets were intended to simulate 15000 MWd/T(M) burnup. The remaining two rods were irradiated until 15000 MWd/T(M). One of them underwent a final ramp with the aim of verifying fabrication processes and studying the behaviour under power transients. BACO (BArra COmbustible) code was used to define the power histories and to analyse the experiments. This paper presents a description of the different experiments and a comparison between the results of the postirradiation examinations and the BACO outputs. (orig.)

    Full Text Available The fish processing operations in Patagonia produce large amounts of waste. The main fishery resource in Argentina is the Argentine hake (Merluccius hubbsi. The ports of the province of Chubut (the most important of which are Puerto Madryn, Rawson and Comodoro Rivadavia, together with Caleta Paula Port (province of Santa Cruz, in the Argentine Patagonia, capture more than 82,000 tons of hake annualy, 80% of which are of M. hubbsi, which is mostly converted into fillets. From this capture, about 2,296 tons of liver would be available for the extraction of oil. To promote the recovery and industrial use of fish oil, in the present study, we determined the variation in the proximate composition and fatty acid profile of Argentine hake waste from the ports mentioned above at different catch times. Proximate composition was determined according of the Official Methods of Analysis (AOAC. Fatty acid profile was analyzed by gas chromatography of the fatty acid methyl esters (FAMEs. A standard mixture of FAMEs was run under identical conditions to identify the compounds on the basis of their retention times. Fatty acids were quantified using heptadecanoic acid (C17:0 as internal standard. The highest lipid recovery (27.0 to 41.8% of total lipids was obtained from the liver fraction. Palmitic acid (C16:0, oleic acid (18:1 n9, docosahexaenoic acid (22:6 n3, eicosapentaenoic acid (20:5 n3 and palmitoleic acid (16:1 were the main constituents. Protein levels in viscera without livers (V-L were higher than those in the liver. The extraction of marine fish oil and the production of fish offal meal from waste from fish factories would contribute to the sustainability of the regional industry, because it would also decrease the volume of waste, with benefits to the environment.El procesamiento de pescados en Patagonia produce gran cantidad de residuos.

    Full text: Dear colleagues from all over the world. Welcome to Argentina. Welcome to Buenos Aires. Welcome to IRPA12. On behalf of the Argentine Radiation Protection Society (SAR), I would like to share with you the story of a dream that came true. Ten years ago, a few dedicated Argentine scientists started dreaming of having an IRPA International Congress in Argentina - the first time in Latin America. At the IRPA International Congress in Hiroshima, an informal presentation was made, which was only supported by SAR and encouraged by IRPA. There was already a bid for the IRPA International Congress in Madrid, strongly supported by the Argentine Government, through the Minister of Foreign Affairs, the Government of the City of Buenos Aires and national academic institutions. At that moment, many countries supported our proposal, sharing with us our dream. We worked very hard in these four years, but we were not alone. The strong support of authorities and staff of the Nuclear Regulatory Authority in Argentina was essential in the organization of IRPA12. Around the world, the cooperation of the International Atomic Energy Agency, the Pan-American Health Organization and the World Health Organization was also fundamental for fulfilment our dream. I would like to mention each of the national and international institutions and colleagues that are supporting IRPA12 with their work, with their funds or with their sponsorship, but there are so many! So, many thanks to all the national and international institutions that are supporting IRPA12; many, many thanks to all the Argentine colleagues and colleagues from all over the world of the different IRPA12 committees, and especially many thanks to all the authorities and colleagues who are here today, with us, sharing this IRPA12 and making real the motto of the Congress: Strengthening Radiation Protection Worldwide. Many thanks and welcome. (author)

    Of the 934 lizard species evaluated by the International Union for the Conservation of Nature (IUCN), at least one-third is threatened with extinction. However, there are no reports of semen cryopreservation efforts for lizards. Invasive Argentine black and white tegus were captured in the Florida Everglades, and sperm was collected postmortem. Initial motility score (IMS; % motile × speed of progression 2 × 100), plasma membrane integrity (IPL), and acrosome integrity (IAC) were recorded. Sperm was diluted in TEST-yolk buffer with a final glycerol or dimethylsulfoxide (DMSO)concentration of 8%, 12%, or 16%, and frozen at 0.3 °C, 1.0 °C, or 6.3 °C/min. At thaw, all variables were expressed as the percentage of initial (%IMS, %IPL, and %IAC). The 0.3 °C freeze rate was more successful than 1.0 °C and 6.3 °C/min in preserving %IMS and %IPL. DMSO preserved %IMS, %IPL, and %IAC better than glycerol. To determine the best overall cryopreservation protocol, a sperm quality index was calculated, giving equal weight to each of the three indicators of cryosurvival. Because there were significant interactions between freeze rate and cryoprotectant concentration, each treatment was compared with all others. The sperm quality index analysis revealed that tegu sperm frozen at 0.3 °C/min with 12% DMSO exhibited the highest postthaw viability compared with all other treatments.

    From its creation in 1967, the Argentine Radioprotection Society (SAR) has as basic purpose promoting all the aspects related with the radiological protection and the nuclear safety. Due to the great increment in the use of radioactive sources in diverse areas, soon it was evident for the SAR the importance and necessity to promote the knowledge of the radioprotection approaches between the users of radioactive sources and ionizing radiations in all its application fields, be these industrial, academic or doctors. From the year 2000, the SAR comes organizing in regular and periodical form basic and specialized courses about radiological safety of radioactive sources for industrial use and profile of oil wells, among others. In this work, the characteristics of the different dictated courses are described whose programs have been developed keeping in mind the requirements of the competent authorities of Argentina. Also, statistical information on the dictated courses and its participants is presented. The number of dictated courses was incremented from 6 (year 2000) up to 16 (year 2005), being also increased significantly the number of participants for course. The dictated courses are theoretical-practical, with a duration average of 20 hs. The educational body is constituted by specialists in the different topics with recognized experience. Its given to the participants notes and support material, as well as copies of the material presented to develop the course. When concluding the courses, its deliver to the participants certifies of attendance and/or approval, as it corresponds. In their headquarters the SAR has didactic facilities and specific equipment for the dictation of the courses. Also accounts with the easiness of dictating those courses outside of their headquarters. This is particularly advantageous for companies or organizations that are seated in points far from the main cities and they should qualify in radiological safety to the personnel but, by

  2. Phosphorus fractions and sorption dynamics in the sediments of two Ca-SO4 water reservoirs in the central Argentine Andes

    Phosphorus (P) fractionation and sorption behavior were studied in the sediments of two calcium-sulfate (Ca-SO4:Ca2+170 mg L-1;SO42-400 mg L-1) water reservoirs in the southern central Argentine Andes-El Carrizal Reservoir (ECR),which stratifies in summer and El Nihuil Reservoir (ENR),which is vertically mixed throughout the year. Sediment size classes reflected the lithology of both basins and the reservoirs relative location:ECR (downstream from a valley adjacent to a mountain environment) had higher clay proportions while the sand fraction was more important in ENR (just next to a mountain environment). In both reservoirs, the chemical composition revealed low alteration and calcium enrichment. Total P content was relatively high (1.1–1.6 mg P kg-1 dry weight) as expected from the contribution of marine formations. P fractionation was dominated by Ca-P (ECR, 69%and ENR, 63%) followed by organic-P (23%) in summer-anoxic ECR and by iron/aluminum (Fe/Al)-P (27%) in oxic ENR. Batch experiments showed that sorption behavior in ECR had a typical Langmuir isotherm plot while in ENR that model fitted only at low dissolved P values (<5 mg P L-1) and co-precipitation evidence was observed at higher P con-centrations. It is proposed that lower Fe/Al-P content in anoxic (ECR) vs. oxic (ENR) sediments results from the P released from iron-bound phosphorus due to sulfate reduction-ferrous sulfide formation in an anoxic environment. This condition should enable ECR sediments to adsorb P into fresh oxidized iron, and ENR sediments to co-precipitate P with calcium due to Fe/Al-P saturation, as observed in batch experiments. This paper constitutes the first description of phosphorus content and dynamics in reser-voir sediments in arid central western Argentina, where water sulfate concentrations are naturally high due to basin lithology.

  3. Plio-Pleistocene paleo-erosion rates as a recorder of orographic barrier uplift in the NW-Argentine Andes (Humahuaca Basin)

    As an integral part of the Eastern Cordillera, the intermontane Humahuaca Basin in the NW Argentine Andes is located in transition between the arid and internally drained Puna Plateau to the west and the humid broken foreland to the east. In combination with moisture-bearing air masses sourced in the Atlantic Ocean and the Amazon Basin, the present-day topographic gradient of the eastern Andean margin comprises an efficient orographic barrier that results in a strong precipitation gradient, with rainfall of more than 2,000 mm/a along the eastern flanks and history of the basin highlights important changes of the depositional system, apparently associated with the transformation from a humid foreland to a fluvially restricted and semi-arid intermontane basin. Similarly, our terrestrial cosmogenic nuclide-derived data indicate an order-of-magnitude decrease in erosion rates at ca. 3 Ma, which suggests a causal link between the onset of uplift-induced semi-arid conditions and decreasing sediment flux into the basin. Ultimately, this dataset may enable a systematic investigation of the long-term causes and consequences of orogenic growth and hydrological changes on spatio-temporal erosion patterns in active mountain areas.

    The authors were involved last years in projects considering diverse decision problems on the use of some regions in Argentine, and also related to rivers or rural services in them. They used sets of multi-criteria decision methods, first discrete when the problem included few distinct alternatives, such as e.g. forestry, traditional or intensive agriculture. For attributes they were different effects, classified then in environmental, economic and social criteria. Extending to other gentler areas, such as at South of the Province of Córdoba, Arg., they have balanced more delicately effects of continuous levels of actions, with a combination of Goal Programming linked methods, and they adopted compromises to have precise solutions. That has shown, and in part open, a line of research, as the setting of such models require various kinds of definitions and valuations, including optimizations, goals with penalties in deviations and restrictions. That can be in diverse detail level and horizon, in presence of various technical and human horizons, and that can influence politics of use of terrain and production that will require public and private agents. The research will consider consideration of use and conservation of soils, human systems and agro productions, and hence models for optimization, preferably in such Goal Programming ways. That will require considering various systems of models, first in theory to be reliable, and then in different areas to evaluate the quality of conclusions, and maybe that successively if results are found advantageous. The Bayesian ways will be considered, but they would require a prospective of sets of precise future states of nature or markets with elicited probabilities, which are neither evident nor decisive for the moment, as changes may occur in years but will be very unexpected or uncertain. The results will be lines of models to aid to establish policies of use of territories, by public agencies setting frames for private

    The Argentine stretch of the del Plata basin crosses regions devoted to extensive and intensive agriculture mostly with chemical pest control. The utilization of pesticides in the region has increased 900% in the last two decades associated with the introduction of biotech crops and direct-seeding techniques. Our objective was to study the occurrence, concentration, and fate of pesticides in surface water and bottom sediments of the principal tributaries and main watercourse of the Paraguay-Paraná River. We sampled 22 sites in the distal positions of the main affluents and main watercourse of the Paraná and report here results from two monitoring campaigns (2010-2012). Surface water and bottom sediments were analyzed according to standardized methods by matrix-solid-phase dispersion and liquid-liquid extraction, respectively. Twenty-three pesticide compounds were analyzed by gas chromatography. The results from both campaigns indicated a generalized but variable distribution in the concentrations detected throughout the basin. The ranges of total measured pesticide concentrations in water and sediments were, respectively, 0.004-6.62 μg/l and 0.16-221.3 μg/kg dry weight. Endosulfans, cypermethrin, and chlorpyrifos were ubiquitous compounds in both environmental compartments and quantitatively the most relevant. All concentrations detected in water were over the recommended guidelines for the protection of aquatic biota. The partitioning indicated a higher affinity for the sediments. Agricultural activity is the source of pesticide-pollution loads, transported by tributaries that reach the main watercourse and alter the quality of the aquatic ecosystem.

    Full Text Available This article seeks to compare the type of coverage that three Argentine newspapers (Clarín, La Nación and Página/12 performed of the so-called "7D" referring to December 7th, 2012, during the month before and the month after that date (from November 7th to January 7th. The Supreme Court of Argentina had established December 7th as a key step in the implementation process of Law of Audiovisual Communication Services (LSCA. From then on, the most important media conglomerate in the country, Grupo Clarín, would have to start the divestment process necessary to comply with the requirements of the new communication law, which had been enacted in 2009. The conceptual basis of the study is the Framing theory. Therefore, a deductive application of generic news frames defined in previous works will be made with the aim of putting in discussion if such frames are effectively adaptable to various topics throughout time and in different cultural contexts or if it is necessary to consider the distinctive features of these scenarios for the definition and persistence of the predominant frames in the news.

    To investigate the incidence and risk factors of disabling injuries to the cervical spine in rugby in Argentina. A retrospective review of all cases reported to the Medical Committee of the Argentine Rugby Union (UAR) and Rugby Amistad Foundation was carried out including a follow up by phone. Cumulative binomial distribution, chi 2 test, Fisher test, and comparison of proportions were used to analyse relative incidence and risk of injury by position and by phase of play (Epi Info 6, Version 6.04a). Eighteen cases of disabling injury to the cervical spine were recorded from 1977 to 1997 (0.9 cases per year). The forwards (14 cases) were more prone to disabling injury of the cervical spine than the backs (four cases) (p = 0.03). Hookers (9/18) were at highest risk of injury (p < 0.01). The most frequent cervical injuries occurred at the 4th, 5th, and 6th vertebrae. Seventeen of the injuries occurred during match play. Set scrums were responsible for most of the injuries (11/18) but this was not statistically significant (p = 0.44). The mean age of the injured players was 22. Tetraplegia was initially found in all cases. Physical rehabilitation has been limited to the proximal muscles of the upper limbs, except for two cases of complete recovery. One death, on the seventh day after injury, was reported. The forwards suffered a higher number of injuries than the backs and this difference was statistically significant. The chance of injury for hookers was statistically higher than for the rest of the players and it was particularly linked to scrummaging. However, the number of injuries incurred in scrums was not statistically different from the number incurred in other phases of play.

  13. Dynamic infrared imaging for cancer: research and development in the Argentine Boron neutron capture therapy

    2009-01-01

    In the framework of the Argentine Boron Neutron Capture Therapy (BNCT) project for treating metastatic cutaneous melanoma, we have initiated a research and development program aimed at obtaining a noninvasive methodology for following-up the treated patients. The technique is called Dynamic Infrared Imaging (DIRI) and comprises the acquisition of infrared images as a function of time of the anatomical part under study, when the region is subjected to a mild cold stress. Vascular, metabolic and regulating differences between normal and tumor tissues appear as differences in the pattern of temperature evolution, which can be correlated with the anatomical and functional aspects of both. Two patients enrolled in the BNCT protocol were studied with DIRI. A good spatial correlation between dose, temperature recovery velocity and skin reaction distributions was observed at the time of maximum expression of the erythematous reaction. Melanoma nodules appear as highly localized hyperthermic regions, surrounded and interconnected by elevated temperature areas. Their temperature recovery velocity after the thermal cold stress was substantially faster than that of normal skin with an appreciably large temperature difference (6 degreesC to 10 degreesC). These tissue differences can be related with the thermal conductivity and metabolic rate as explained by a simple one-directional heat transport model. Compared with other imaging modalities (CT and Doppler ultrasound) DIRI has had a similar ability for confirming the already diagnosed nodules. Together with the clinical observation, DIRI provides a potentially useful amount of information, at a competitive cost-benefit relationship suitable for performing a non-invasive functional assessment of this kind of cutaneous lesions and the evaluation of the acute skin reaction following irradiation.

    The Argentine Nuclear Regulatory Authority (NRA) has appointed a consultants body that advises its Board of Directors on aspects related to authorization's granting to individuals for the use of radioisotopes and ionizing radiation in medicine, research and industry. Such committee, whose existence goes back to the year 1958, is integrated by prominent professionals knowledgeable about ionizing radiation and radioisotopes applications in the medical, biomedical and industrial fields, representing important professional associations or institutions related to the practices in question. Originally, the committee was conceived as a consultation body to fulfil two important functions: To produce, in a regular way, authorized opinions at experts level to settle down questions relative to the regulation of practices, new at that time in the country, and To submit to a peer review applications for individual authorization for different uses of ionizing radiation previously it's granting by the Regulatory Authority. In this paper the role of the advisory council is analyzed from a historical perspective trying to emphasize an outstanding aspect not sufficiently analyzed linked to the capability that advisory bodies, with representative users' presence, can reach in the interpretation of regulatory standards based on a performance philosophy. Such approach outlines the permanent dilemma about the performance level of the licensee that should satisfy the Regulatory Authority. Once the broad objectives of radiation protection has been defined professional criteria is required for applying them to different practices. Balance between flexibility and avoidance of excessive uncertainty is desirable. In the authors' opinion the inclusion, inside the regulator's structure of consultants bodies giving direct participation to qualified stakeholders, far from harming the necessary independence that should characterize the regulator, on the contrary, allows to have an excellent social

    The Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) with assistance from the U.S. Department of Energy (DOE) began a program to evaluate environmental sampling capabilities at laboratories in Argentina and Brazil in June 1998. The program included staff training conducted in South America and the United States. Several laboratory evaluation exercises were also conducted using standard swipe samples prepared by the International Atomic Energy Agency (IAEA) and a National Institute of Standards and Technology Standard Reference Material 1547, Peach Leaves. The results of these exercises demonstrated that several laboratories were capable of accurately determining the total uranium and uranium isotopic distribution in the peach leaves. To build on these successes, another exercise using standard swipe samples prepared by the IAEA was conducted. A total of 8 sets of 15 swipe samples were prepared and distributed to the six ABACC support laboratories and to two of DOE's Network of Analytical Laboratories (NWAL) that support IAEA's environmental sampling program Throughout this project, the ABACC laboratories have shown steady progress in contamination control and improvements to the accuracy and precision of their measurements. The results of the latest exercises demonstrate that ABACC now has support laboratories in both Argentina and Brazil that have the capability to measure both the amount and isotopic composition of uranium at levels expected in typical environmental samples (i.e., sub-microgram quantities). This presentation will discuss the final results for the exercise with uranium swipe samples and discuss future activities to develop measurement capabilities for total and isotopic plutonium in environmental samples.

  17. Sedimentology of middle ordovician carbonates in the Argentine precordillera: evidence of regional relative sea-level changes

    Keller, M.; Eberlein, S.; Lehnert, O.

    The Las Aguaditas Formation in the Argentine Precordillera of San Juan is the only Ordovician carbonate sequence deposited on a slope. Spiculites, mudstones and calcisiltites represent the autochthonous sediments, characterized by a fine lamination, rare fossils and their dark colour. The pelagic fauna consists of rare radiolarians/calcispheres, trinucleid trilobites, graptolites and conodonts. The latter are typical of an open marine environment and proved a Llanvirn—Llandeilo age for the Las Aguaditas Formation. In the upper part of the succession there are several intercalations of megabreccias. Their thickness decreases from about 20 to 4 m towards the top of the formation, accompanied by an increasing amount of carbonate turbidites. The clasts of the breccias are derived from the slope as well as the platform. Each of the megabreccia horizons represents a system of channels, lobes and interchannel deposits, which together form a slope apron. On top of the lower breccia a small biostrome developed, where bryozoans and crinoids are preserved in an autochthonous position. Sedimentation of the Las Aguaditas Formation started with the drowning of the underlying carbonate platform (San Juan limestones). Near the Arenig-Llanvirn boundary, a rapid ecstatic sea-level rise led to the deposition of graptolitic black shales and mudstones. Upwards, allochthonous carbonates become increasingly abundant. The onset of megabreccia deposition coincides with a major relative sea-level fall, caused by block movements in connection with rifting. The subsequent transition from breccia formation towards turbiditic sedimentation corresponds to an environmental shift from the slope towards the toe of slope and basin and marks a renewed moderate sea-level rise.

  18. The peri-urban interface and house infestation with Triatoma infestans in the Argentine Chaco: an underreported process?

    Directory of Open Access Journals (Sweden)

    Yael M Provecho

    2014-10-01

    Full Text Available Peri-urban infestations with triatomine bugs, their sources and their dynamics have rarely been investigated. Here, we corroborated the reported occurrence of Triatoma infestans in a peri-urban area and in neighbouring rural houses in Pampa del Indio, in the Argentine Chaco, and identified its putative sources using spatial analysis and demographic questionnaires. Peri-urban householders reported that 10% of their premises had triatomines, whereas T. infestans was collected by timed manual searches or community-based surveillance in only nine (3% houses. Trypanosoma cruzi-infected T. infestans and Triatoma sordida were collected indoors only in peri-urban houses and were infected with TcV and TcI, respectively. The triatomines fed on chickens, cats and humans. Peri-urban infestations were most frequent in a squatter settlement and particularly within the recently built mud houses of rural immigrants, with large-sized households, more dogs and cats and more crowding. Several of the observed infestations were most likely associated with passive bug transport from other sources and with active bug dispersal from neighbouring foci. Thus, the households in the squatter settlement were at a greater risk of bug invasion and colonisation. In sum, the incipient process of domestic colonisation and transmission, along with persistent rural-to-urban migratory flows and unplanned urbanisation, indicate the need for active vector surveillance and control actions at the peri-urban interface of the Gran Chaco.

    The Institute of Radiation Protection and Nuclear Safety Institute (IRSN) organized an international biological dosimetry intercomparison, at the SILENE experimental reactor (Valduc, France), simulating different criticality scenarios: bare source 4 Gy, lead shield source 1 and 2 Gy and gamma pure 60 Co source 2 Gy. Fifteen laboratories were involved in this exercise, including the Argentine Biological Dosimetry Laboratory. The purposes of the intercomparison were: 1) To compare the unstable chromosome aberration (UCA) frequency observed by the different laboratories; and 2) To compare the dose estimation for gamma rays and neutrons. The objects of the present work were: I) To compare the mean frequency of UCA observed by the Argentine laboratory with the mean frequency observed by the participant laboratories as a whole. II) To compare the dose estimates performed by the Argentine lab with those estimated by the other laboratories involved in the second stage of the intercomparison. Overall, the mean frequencies of UCA and the correspondent 95% confidence limits obtained by the Argentine lab were consistent with the results obtained by the laboratories as a whole. For the gamma pure scenario, smaller variations were observed among laboratories in terms of dose (CV=18,2%) than in terms of frequency (CV=30,1%). For the mixed field scenarios, only four laboratories, including the Argentine lab, estimated gamma and neutron components of the total dose and just two (Argentine lab and lab 12) were in agreement with the given physical doses. The 1 Gy experiment presented lesser variations both in terms of frequency and dose than the other two scenarios. For the 4 and 2 Gy experiments, variations in neutron dose were more significant than variations in gamma dose, related to the magnitude of the dose. The results suggest that intercomparison exercises jointly with the accreditation of biological dosimetry by cytogenetic service laboratories, in compliance with ISO

    Full Text Available Practices of other-initiated repair deal with problems of hearing or understanding what another person has said in the fast-moving turn-by-turn flow of conversation. As such, other-initiated repair plays a fundamental role in the maintenance of intersubjectivity in social interaction. This study finds and analyses a special type of other-initiated repair that is used in turn-by-turn conversation in a sign language: Argentine Sign Language (Lengua de Señas Argentina or LSA. We describe a type of response termed a ‘freeze-look’, which occurs when a person has just been asked a direct question: instead of answering the question in the next turn position, the person holds still while looking directly at the questioner. In these cases it is clear that the person is aware of having just been addressed and is not otherwise accounting for their delay in responding (e.g., by displaying a ‘thinking’ face or hesitation, etc.. We find that this behavior functions as a way for an addressee to initiate repair by the person who asked the question. The ‘freeze-look’ results in the questioner ‘re-doing’ their action of asking a question, for example by repeating or rephrasing it. Thus we argue that the ‘freeze-look’ is a practice for other-initiation of repair. In addition, we argue that it is an ‘off-record’ practice, thus contrasting with known on-record practices such as saying ‘Huh?’ or equivalents. The findings aim to contribute to research on human understanding in everyday turn-by-turn conversation by looking at an understudied sign language, with possible implications for our understanding of visual bodily communication in spoken languages as well.

  6. Adaptation to Interannual and Interdecadal Climate Variability in Agricultural Production Systems of the Argentine Pampas

    Agricultural ecosystems play a central role in world food production and food security, and involve one of the most climate-sensitive sectors of society-agriculture. We focus on crop production in the Argentine Pampas, one of the world's major agricultural regions. Climate of the Pampas shows marked variability at both interannual and decadal time scales. We explored the scope for adaptive management in response to climate information on interannual scales. We show that different assumptions about what decision makers are trying to achieve (i.e., their objective functions) may change what actions are considered as "optimal" for a given climate context. Optimal actions also were used to estimate the economic value of forecasts of an ENSO phase. Decision constraints (e.g., crop rotations) have critical influence on value of the forecasting system. Gaps in knowledge or misconceptions about climate variability were identified in open-ended "mental model" interviews. Results were used to design educational interventions. A marked increase in precipitation since the 1970s, together with new production technologies, led to major changes in land use patterns in the Pampas. Continuous cropping has widely replaced agriculture-pasture rotations. Nevertheless, production systems that evolved partly in response to increased rainfall may not be viable if climate reverts to a drier epoch. We use historical data to define a range of plausible climate trajectories 20-30 years hence. Regional scenarios are downscaled using semi-parametric weather generators to produce multiple realizations of daily weather consistent with decadal scenarios. Finally, we use the synthetic climate, crop growth models, and realistic models of decision-making under risk to compute risk metrics (e.g., probability of yields or profits being below a threshold). Climatically optimal and marginal locations show differential responses: probabilities of negative economic results are much higher in currently

    The effect of seasonality on Argentine propolis collected during one year on its phenolic and flavonoid content and on the growth of Gram-positive and Gram-negative antibiotic resistant bacteria and Candida species was evaluated. Extracts of propolis samples collected in the summer and spring showed higher phenolic and flavonoid contents than the samples collected in other seasons (5.86 to 6.06 mg GAE/mL and 3.77 to 4.23 mg QE/mL, respectively). The propolis collected in summer and autumn showed higher antibacterial activity (30 microg/mL) than the other samples (MIC values between 30 and 120 microg/mL). No antibacterial activity was detected against Gram-negative bacteria. Also, these extracts were able to inhibit the development of five Candida species, with MFC values of 15-120 microg/mL. Pharmaceutical formulations containing the more active propolis extract were prepared. The hydrogel of acrylic acid polymer containing summer propolis extract as an antimicrobial agent showed microbiological, physical and functional stability during storage for 180 days. The pharmaceutical preparation, as well as the propolis extracts, was active against Candida sp. and antibiotic-multi-resistant Gram-positive bacteria. These results reveal that propolis samples collected by scraping in four seasons, especially in summer in Calingasta, San Juan, Argentina, can be used to obtain tinctures and hydrogels with antibacterial and antimycotic potential for topical use.

    An exercise of intercomparison organized by the Nuclear Regulatory Authority was carried out during the year 2000 for the determination of uranium in samples of water and urine. The exercise was designed to compare the values of uranium obtained by the different laboratories for the same sample, and to promote the identification of the uncertainties linked with the process of obtaining the results. Six laboratories that usually do this type of analysis participated in the exercise. The values informed by the laboratories are presented, as well as an evaluation of the performance of each laboratory

    Full Text Available O presente trabalho busca resgatar as origens históricas da crise argentina. Argumentamos que o modelo de liberalização econômica subjacente ao Plano de Conversibilidade tem suas raízes na formação da economia agroexportadora, que entre o final do século XIX e primeiras décadas do século XX deu as bases para a construção de um país próspero. Por outro lado, a década de 1990 introduziu uma heterogeneidade social que não guarda relação estreita com as principais heranças do modelo liberal anterior.In this paper we look for the historical genesis of the Argentine crisis. We argue that the economic liberalization model, implicit of the Convertibility Plan, has its roots in establishment of the agro-exporting economy on which, between the end of the 19th century and the first decades of the 20th century, a prosperous country was formed. On the other hand, the 1990 decade introduced a social heterogeneity that holds no relation to the main heritage of the previous liberal model.

    The continental territory of the Argentine Republic owns 75% of its surface under arid and semiarid conditions to the west of the meridian of 64°. Wind erosion is the main physical cause of desertification. In the Pampena area, studies showed that the sandy loam soils were more pronounced than the sandy loam with significant losses of organic matter, decreases in the cation exchange capacity and modification of the mineral composition of the very fine sand fraction (From 73 to 100 μm), with increases in the proportion of heavy minerals (magnetite) relative to light (quartz). In the Patagones department, Buenos Aires province, the soils with a sandy-loamy texture, which are transported by wind and deposited on calcium carbonate (tosca), with little moisture retention and susceptible to wind erosion. In the 1980s and 1990s, increases in rainfall above the historical average led to a shift of the isohytes towards the southwest, leading to agricultural intensification that caused greater pressure on the soil and native vegetation. This advance on the native vegetation within the Patagones produced a reduction between 1975 and 2009 of 432,280 ha, leaving only 31% of the area covered by native forest - shrub xerophyte today. Between 2005-2009, the call "agricultural drought" caused losses in crops, wheat - oats and natural pastures associated with the native forest, causing a significant deterioration of the soil, exposing them to wind erosion. Remote sensors represent a very valuable technology for the mapping and evaluation of soil erosion. The availability of multispectral images allows the mapping and monitoring of changes in the dynamics of the erosion process. The objective of this work was to make an expeditious diagnosis of the surface affected by wind erosion and to evaluate the degree to which the soils destined for agriculture and livestock were affected. For this purpose, Terra's MODIS (Moderate-Resolution Imaging Spectroradiometer) sensor information was

    The two local crustacean species Hyalella curvispina and Macrobrachium borelli were chosen for assessment of agricultural contamination in two streams (Horqueta and Maguire) in the Argentine pampa. In parallel with in situ bioassays of both species, the population dynamics and the organismic drift of H. curvispina were investigated throughout the main period of insecticide application, from December 2001 to March 2002. In Maguire none of the current-use insecticides (chlorpyrifos, alpha-cypermethrin, and endosulfan) in question were detected throughout the sampling period. During 1-week intervals with no contamination by insecticides the survival rate of H. curvispina varied between 77 +/- 6% (+/- SE, n = 4) and 85 +/- 3%. In Horqueta during a week with a peak insecticide contamination of 64 microg/kg chlorpyrifos in the suspended particles, a mortality of 100% was observed in the in situ bioassays for both species, H. curvispina and M. borelli. At the same time, in Maguire H. curvispina showed reduced survival rates of 23 +/- 5% and 25 +/- 18% at the two sites, while the survival rate of M. borelli was 60 +/- 11% upstream and 93 +/- 5% downstream, below a wetland. During the period with 100% mortality of H. curvispina in Horqueta, the population density of this species decreased correspondingly, from 106 +/- 26 to 0 individuals/m(2). We conclude that in situ bioassays can be successfully linked to in-stream population dynamics for the same species and that this link is very useful for interpreting causal exposure-effect relationships.

  19. Differences in production, carbon stocks and biodiversity outcomes of land tenure regimes in the Argentine Dry Chaco

    Rising global demand for agricultural products results in agricultural expansion and intensification, with substantial environmental trade-offs. The South American Dry Chaco contains some of the fastest expanding agricultural frontiers worldwide, and includes diverse forms of land management, mainly associated with different land tenure regimes; which in turn are segregated along environmental gradients (mostly rainfall). Yet, how these regimes impact the environment and how trade-offs between production and environmental outcomes varies remains poorly understood. Here, we assessed how biodiversity, biomass stocks, and agricultural production, measured in meat-equivalents, differ among land tenure regimes in the Dry Chaco. We calculated a land-use outcome index (LUO) that combines indices comparing actual vs. potential values of ‘preservation of biodiversity’ (PI), ‘standing biomass’ (BI) and ‘meat production’ (MI). We found land-use outcomes to vary substantially among land-tenure regimes. Protected areas showed a biodiversity index of 0.75, similar to that of large and medium-sized farms (0.72 in both farming systems), and higher than in the other tenure regimes. Biomass index was similar among land tenure regimes, whereas we found the highest median meat production index on indigenous lands (MI = 0.35). Land-use outcomes, however, varied more across different environmental conditions than across land tenure regimes. Our results suggest that in the Argentine Dry Chaco, there is no single land tenure regime that better minimizes the trade-offs between production and environmental outcomes. A useful approach to manage these trade-offs would be to develop geographically explicit guidelines for land-use zoning, identifying the land tenure regimes more appropriate for each zone.

RESULTS: Of the 1,328 participating students aged 13 to 15 years old, 51.9% reported drinking alcohol in the previous month, with higher rates among males (p = 0.04 and older students (p < 0.01. Both male and female drinkers were nearly twice as likely as non-drinkers to report being physically attacked, being in a physical fight, and having thoughts about self-directed violence. Among drinkers, those who reported poor mental health, were victims of bullying, used tobacco or drugs, or skipped school without permission were approximately twice as likely as other drinkers to have engaged in violent activities. CONCLUSION: Public health interventions targeting violence among young adolescents should be developed in combination with alcohol education programs.

    Full text: In the new framework of nuclear renaissance in the world in general, and in Argentina in particular, proper and efficient management of information and knowledge produced in the past and to be produced during renaissance becomes critically important. The fact that in the nuclear sector across the world human resources are going through significant change as a result of the massive number of experts who are retiring from the workforce, the ensuing general gap, the new generation of workers who are joining the nuclear rank and file with different training, values and cultural beliefs, and the slow information and knowledge transfer process call for carefully considering and assessing new methods to manage information and knowledge. This paper discusses the topic of knowledge maps as a method to adapt historical information and knowledge and to make it more readily available for future workers; the paper also deals with a new management approach to such information. Knowledge maps probably represent an up-to-date method to manage both historical and new information and knowledge, adapting to a number of new cultural features, including but not limited to the intensive use of information technologies and the tendency to summarize and integrate concepts. A distinguishing feature of this new method of organizing information and knowledge is the need for a closer interrelation across the organisation's sectors. As a result, knowledge maps help create and improve manuals and procedures related to the specific tasks performed in the institution, based on the analysis carried out by those creating the maps. This tool also helps better analyze the tasks already conducted or to be conducted by workers, all of which optimizes the job description process in the area of human resources. Another benefit of knowledge maps is that they help preserve the information and knowledge that can be used to train the staff in merely technical or induction issues as well as in an

    Species of the genus Trichoderma are economically important as biocontrol agents, serving as a potential alternative to chemical control. The applicability of Trichoderma isolates to different ecozones will depend on the behavior of the strains selected from each zone. The present study was undertaken to isolate biocontrol populations of Trichoderma spp. from the Argentine wheat regions and to select and characterize the best strains of Trichoderma harzianum by means of molecular techniques. A total of 84 out of the 240 strains of Trichoderma were able to reduce the disease severity of the leaf blotch of wheat. Thirty-seven strains were selected for the reduction equal to or greater than 50% of the severity, compared with the control. The percentage values of reduction of the pycnidial coverage ranged between 45 and 80%. The same last strains were confirmed as T. harzianum by polymerase chain reaction amplification of internal transcribed spacers, followed by sequencing. Inter-simple sequence repeat was used to examine the genetic variability among isolates. This resulted in a total of 132 bands. Further numerical analysis revealed 19 haplotypes, grouped in three clusters (I, II, III). Shared strains, with different geographical origins and isolated in different years, were observed within each cluster. The origin of the isolates and the genetic group were partially related. All isolates from Paraná were in cluster I, all isolates from Lobería were in cluster II, and all isolates from Pergamino and Santa Fe were in cluster III. Our results suggest that the 37 native strains of T. harzianum are important in biocontrol programs and could be advantageous for the preparation of biopesticides adapted to the agroecological conditions of wheat culture.

    Patients with Gaucher type 1 (GD1) throughout Argentina were enrolled in the Argentine bone project to evaluate bone disease and its determinants. We focused on presence and predictors of bone lesions (BL) and their relationship to therapeutic goals (TG) with timing and dose of enzyme replacement therapy (ERT). A total of 124 patients on ERT were enrolled in a multi-center study. All six TG were achieved by 82% of patients: 70.1% for bone pain and 91.1% for bone crisis. However, despite the fact that bone TGs were achieved, residual bone disease was present in 108 patients on ERT (87%) at time 0. 16% of patients showed new irreversible BL (bone infarcts and avascular osteonecrosis) despite ERT, suggesting that they appeared during ERT or were not detected at the moment of diagnosis. We observed 5 prognostic factors that predicted a higher probability of being free of bone disease: optimal ERT compliance; early diagnosis; timely initiation of therapy; ERT initiation dose ≥45 UI/kg/EOW; and the absence of history of splenectomy. Skeletal involvement was classified into 4 major phenotypic groups according to BL: group 1 (12.9%) without BL; group 2 (28.2%) with reversible BL; group 3 (41.9%) with reversible BL and irreversible chronic BL; and group 4 (16.9%) with acute irreversible BL. Our study identifies prognostic factors for achieving best therapeutic outcomes, introduces new risk stratification for patients and suggests the need for a redefinition of bone TG. Am. J.

    After 4 years of deepening recession, Argentina's economy plummeted after default in 2002. This crisis critically affected health expenditures and triggered acute rationing. Our objective was to explore health decision-makers' knowledge and attitudes about economic evaluations (EE) and whether health technology assessment (HTA) were increasingly used for decision making. A qualitative design based on semistructured interviews and focus groups was used to explore how decision makers belonging to different health sectors implement resource allocation decisions. Informants were mostly unaware of EE. The most important criteria mentioned to adopt a treatment were evidence of effectiveness, social/stakeholder demand, or resource availability. Despite general positive attitudes about EE, knowledge was rather limited. Although cost considerations were widely accepted by purchasers and managers, clinicians argued about these issues as interfering with the doctor-patient relationship. Other important perceived barriers to HTA use were lack of confidence in the transferability of studies conducted in developed countries and institutional fragmentation of the Argentine healthcare system. The new macroeconomic context was cited as a justification of implicit rationing measures. Although explicit priority setting was implemented by many purchasers and managers, HTA was not used to improve technical and/or allocative efficiency. The crisis seems to be a strong incentive to extend the use of HTA in Argentina, provided decision makers are aware as well as involved in the generation of local studies.

  9. Paleogeographic significance of Clavohamulus hintzei Miller (Conodonta) and other Ibexian conodonts in an early Paleozoic carbonate platform facies of the Argentine Precordillera

    Pre-Tremadocian conodonts and trilobites and Tremadocian conodonts are reported from the Cambrian and Ordovician La Silla Formation in the Cerro La Silla section in east-southeast Ja??chal, San Juan Province, Argentina. A shallow marine conodont fauna contains elements of Clavohamulus hintzei Miller, a common species in North America, but reported for the first time from the early Paleozoic platform carbonates of the western Argentine Precordillera. The presence of this species suggests a correlation with the Clavohamulus hintzei conodont subbiozone of the Cordylodus intermedius conodont biozone in North America, considered Early Ordovician (Skullrockian Stage, Ibexian Series) in North America, but by South American and European standards, this biozone would be of latest Cambrian age. C. hintzei and associated conodonts of the La Silla Formation are typical of the tropical faunas of the North American Midcontinent Faunal Province; Late Cambrian trilobites from lower in the formation also are typical North American taxa. The presence of these faunas in the platform carbonates is consistent with plate reconstructions suggesting that the Precordillera was in a tropical or subtropical position close to Laurentia during the late Precambrian and early Paleozoic. These new paleontological data provide one more argument for recent models of the Precordillera as a displaced terrane derived from the Ouachita Embayment at the southern margin of Laurentia.

    Full Text Available For the first time a taxonomic and ecological study of species belonging to Helicostomella was performed over a mesoscale spatial distribution by examining ca. 3000 loricae collected in Argentine shelf waters during the austral autumn. Microscopic and statistical analysis revealed that the general shape and the oral diameter remained practically constant in the whole area surveyed, despite a continuous length fluctuation of ca. 300 µm, which includes the entire range present in eight previously reported species. Consequently, we consider that the genus may be represented only by H. subulata, whose strong fluctuations in length (mostly attributed to an increase in the collar length, density and biomass seem to respond to temperature, food availability and front-related processes. In Buenos Aires coastal waters associated with a quasi permanent estuarine front (40-40.5°S, mixed conditions would favour moderate abundances of long loricae, whereas in northern (42.5-45.5°S and southern (46-54.5°S Patagonian waters, high (103 ind. L-1 and low (< 5 ind. L-1 densities of short loricae seem to be a consequence of stratification and encystment, respectively. The non-occurrence of the species at 41-42°S, together with a three-fold reduction in length-related parameters between specimens from Buenos Aires and Patagonian waters, suggests a disjunct distribution.

    Listronotus bonariensis (Argentine stem weevil) is a stem-boring weevil that has become a major pasture pest in New Zealand, and cool climate turf grass in Australia. This species is also frequently found in native tussock grassland in New Zealand. Laboratory and field trials were established to determine the risk posed to both seedlings and established plants of three native grass species compared to what happens with a common host of this species, hybrid ryegrass (L. perenne X L. multiflorum). Adult weevil feeding damage scores were higher on Poa colensoi and Festuca novae-zelandiae than Chionochloa rigida. Oviposition was lower on P. colensoi than hybrid ryegrass, and no eggs were laid on F. novae-zelandiae. In field trials using the same four species established as spaced plants L. bonariensis laid more eggs per tiller in ryegrass in a low altitude pasture site than in ryegrass in a higher altitude site. No eggs were found on the three native grass species at the tussock sites, and only low numbers were found on other grasses at the low altitude pasture site. Despite this, numbers of adult weevils were extracted from the plants in the field trials. These may have comprised survivors of the original weevils added to the plants, together with new generation weevils that had emerged during the experiment. Irrespective, higher numbers were recovered from the tussock site plants than from those from the pasture site. It was concluded that L. bonariensis is likely to have little overall impact, but a greater impact on native grass seedling survival than on established plants.

The marker most extensively associated with breast cancer is MUC1. The objective of the study was to analyze prognostic and risk factors in relation to tumor markers in order to clarify breast cancer biology. A total of 349 primary tumor samples and lymph nodes from breast cancer patients were studied. Risk and prognostic factors were considered. An immunohistochemical approach was applied and an extensive statistical analysis was performed, including frequency analysis and analysis of variance. Correlation among variables was performed with principal component analysis.Results: All the antigens showed an increased expression according to tumor size increment; moreover, sialyl Lewis x expression showed a significant increase in relation to disease stage, whereas Tn and TF presented a positive tendency. Vascular invasion was related to sialyl Lewis x expression and number of metastatic lymph nodes. Taking into account risk factors, when a patient had at least one child, Lewis antigens diminished their expression. In relation to breastfeeding, sialyl Lewis x expression diminished, although its apical expression increased.Conclusion: Associations between MUC1 and carbohydrate antigens and risk and prognostic factors show the complexity of the cellular biological behavior that these antigens modulate in breast cancer.Keywords: breast cancer, Argentine women, risk factors, prognostic factors, antigenic expression

    The Argentine Precordillera is an archetypal retroarc fold-and-thrust belt that records tectonics associated with changing subduction regimes. The interactions between exhumation and faulting in the Precordillera were investigated using apatite and zircon (U-Th-Sm)/He and apatite fission track thermochronometry from the Precordillera and adjacent geologic domains. Inverse modeling of thermal histories constrains eastward in-sequence rock cooling associated with deformation and erosion from 18 to 2 Ma across the Central Precordillera tracking thrusting during this time. The youngest AHe ages (5-2 Ma) and highest erosion rates are located in the eastern and western extremities of the Precordillera and indicate that recent denudation is concentrated at its structural boundaries. Moreover, synchronous rapid Pliocene cooling of the Frontal Cordillera, Eastern Precordillera, and Sierra del Valle Fértil was coeval with initiation of basement-involved faulting in the foreland. Detrital zircon U-Pb geochronology from the ca. 16-8.1 Ma Bermejo foreland basin strata suggests fluvial connectivity westward beyond the Frontal Cordillera to the Main Cordillera and Coast Range followed by an important shift in sediment provenance at ca. 10 Ma. At this time, we suggest that a substantial decrease in Permo-Triassic igneous sources in the Frontal Cordillera and concurrent increase in recycled zircons signatures of Paleozoic strata are best explained by uplift and erosion of the Precordillera during widening of the thrust-belt. Bedrock thermochronology and modeling indicate a 2-6 Myr lag time between faulting-related cooling in the hinterland and the detrital record of deformation in the foreland basin, suggesting that for tectonically active semi-arid settings, bedrock cooling may be more sensitive to onset of faulting. We suggest that high erosion rates in the Frontal Cordillera and Eastern Precordillera are associated with increased interplate coupling during shallowing of the

    In 2006, the Argentine Nuclear Regulatory Authority has initiated a regulatory knowledge management process to face the loss of knowledge resulting from retiring experts, the generation gap, and the existing need to train new human resources. A number of projects have been started together with the technical assistance of the National Public Administration Institute to preserve knowledge and render it explicit for the coming generations. These projects include 'The History of the Expert's Learning Process' in which the majority of the most critical experts have been interviewed so far. The results of this project help envision a training structure and prospective projects. An Internet Site has also been created on the Intranet in order to render knowledge explicit and facilitate the tools for knowledge management initiatives. Furthermore, ARN's knowledge map project has also been started.

    The Argentine stem weevil (Listronotus bonariensis) was an economically important pest in New Zealand pastures until the release of the parasitoid Microctonus hyperodae. This contribution uses historical data to investigate the regulation of the pest populations prior to, and somewhat during, the establishment of this parasitoid in dryland Canterbury, New Zealand. Thus, a significant goal of this study is to provide an L. bonariensis population dynamics baseline for any future work that aims to analyse the full effects of M. hyperodae on the weevil, now that equilibrium with the weevil host has been reached.The population dynamics of L. bonariensis, based on a life-table approach, were investigated using data collected regularly for eight years from populations in Canterbury, New Zealand. The key factor affecting end-of-season L. bonariensis density was found to be variation in second generation fourth instar prepupal and pupal mortality. This may have been caused by arrested development and ongoing mortality resulting from the onset of cooler autumnal conditions.A compensatory response was found in recruitment to the second summer weevil generation, whereby the realised fecundity of the emergent first summer generation of weevils was found to be negatively related to the density of adult weevils per ryegrass tiller. This is the first time that this has been found via long-term population analysis of L. bonariensis, although indications of this have been found elsewhere in caging, pot and small plot experiments.In this study, the effect of the parasitoid biocontrol agent Microctonus hyperodae on L. bonariensis population dynamics was unclear, as the analysis covered a period when the parasitoid Microctonus hyperodae was introduced and still establishing. It does, however, raise important questions for future analysis in terms of the interaction between parasitism and unrealised fecundity.The results in this contribution also highlighted regional differences

    The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia. The psychiatry at the hospices with the German influence from Jakob developed to the modern neuropsychiatry with Juan Carlos Goldar. The argentine school of psychology by the holism and the psychoanalysis influence do not accept the neuropsychology until 1960 where was included at the school of psychology from the university of Buenos Aires (UBA) with the first linguistics works of Juan Azcoaga. At the 80, began the North American influence of the neurology with authors like Carlos Mangone (dementia), Ramon Leiguarda (apraxia), Sergio Starkstein (depression and apathy) and Ricardo Allegri (memory and Alzheimer). In 1982 the Argentine Neuropsychological Society was founded and in 1987 was the working group of dementia from the Argentine Neurological Society. At this moment, Aldo Ferreres organized the chair of neuropsychology at the school of psychology (UBA). Nowadays, the growing as discipline is in context of the psychology, neurology and psychiatry in the way of the recent cognitive neurosciences.

Para ello el trabajo presenta los resultados de una investigación sobre el alcance, los mecanismos, las motivaciones y los criterios de las designaciones partidarias en el Estado federal argentino, con particular énfasis en lo ocurrido durante la presidencia de Néstor Kirchner (2003- 2007. El argumento más general sostiene que las designaciones han devenido en este período en una herramienta esencial para lograr un control efectivo sobre el aparato estatal mientras que sirven, simultáneamente, para reconfigurar las élites partidarias del peronismo bajo el liderazgo del presidente. Los datos, surgidos de una amplia serie de entrevistas a expertos, permiten finalmente ofrecer un nuevo marco teórico para estudiar el vínculo entre partido y gobierno en el contexto de la democracia argentina contemporánea.This article contributes to the understanding of the organizational structures of peronism, Argentine dominant political force, on the basis of a study on partisan appointments. It presents the main findings of a research on the scope, the workings, the motivations, and the criteria of partisan appointments in the Argentine state, with particular attention to Néstor Kirchner administration (2003-2007. The more general argument contends that appointments became in this period a crucial tool to control the state apparatus while, at the same time, they made it possible to renovate Peronist partisan elites under the leadership of the president. The data, obtained from a large series of expert interviews, make it possible to offer a new theoretical framework for the understanding of party-government linkages in contemporary Argentine democracy.

The general exposition of the research is focused on showing that the topic of the failure acquired its decisive attributes during the first half of the 20th century, through a complex dynamic, comprised of diverse channels which should be captured in their specificity, although without losing sight of the more general movement of which they form a part: seen globally, this movement contributed to the erosion of an entire ideological-cultural configuration, which I call "argentine illusion". The backdrop of the process was none other than the growing social complexity, the greater and more dissonant discursive diversification (Tulio Halperín and the profound hegemony crisis which the country experienced throughout the period.

    In this work one simulates, using the program MESSAGE, the generation park electric of the Argentine Republic and their possible expansion, with restrictions in the readiness of fossil fuels. This, as other models of planning energetics promoted by IAEA, optimizes the expansion of the net having as function objective the smallest cost in the system. 25 years they were simulated, adopting like base the anus 2000 and considering different scenarios of internal and external demands. It was analysed the increase of the demand with restrictions in the readiness of the natural gas in the winter periods, since the Argentinean electric system has a great dependence of this fuel. To cover the increase of the electric demand, were selected the machines and fuels, at the moment available, with more technical and economic possibilities. In the scenarios without restrictions to the use of natural gas the program selects to the nuclear power station of Atucha II, to the increase of bench mark of the hydraulic power station of Yacireta and combined cycles that burn natural gas. In those in that the supply of natural gas is limited, it selects previously besides the signal ones, other nuclear power stations, other hydroelectric projects and turbines of gas operating with gas oil to cover the top requirements.

    Full Text Available When the process of democratization in the Southern Cone began, Argentine and Uruguayan political exiles began returning to their countries of origin. As part of that process, between 1983 and 1986, in Argentina and in Uruguay emerged various social organizations that were concerned with helping the exiles in their reintegration into the country. This article explores the responses of these organizations in two different analytical keys. Firstly, it acknowledges the exchange of knowledge, concerns, and ways of working between Argentine social organisations and Uruguay in the process of formulation of certain measures and programmes for the reintegration of returnees. In this way, this work seeks to break with the comparisons in the strict sense to explore health care networks between different actors from both countries. Secondly, we reflect on a tension that emerges from the network: despite the mutual influences, assistance programmes had important differences between both cases. As a result, this article offers some interpretations about these differences, emphasizing problems that are closely linked with modes that are developed "in each country democratic transitions" and, especially, where the subject of the return had in each post-dictatorship agenda

    Full Text Available Equine viral arteritis (EVA is a contagious viral disease that frequently causes mild or subclinical infections in adult horses. Only one EAV serotype has been described. However, there are differences in antigenicity, pathogenicity and neutralization characteristics of virus field strains. The interaction of two viral proteins, GP5 and M, is critical for infectivity and amino acid changes in the GP5 sequences have an effect on the neutralizing phenotype, regardless the effects of other viral proteins. The objective of the present study was to evaluate the neutralization phenotypes of the 5 unique Argentine EAV strains reported and to compare them with the neutralization phenotypes of the EAV-UCD reference strain, with special emphasis on the analysis of M and GP5 proteins. The strains had a similar neutralization phenotype pattern when anti-EAV serum, derived from EAV seropositive horses, was used in the analysis. Meanwhile, low titers were observed when equine polyclonal anti-EAV reference sera were used in the assay. Argentine strains have almost the same amino acid substitutions, with the exception of LP01 strain, that mainly involves the first variable region V1, especially in neutralization sites B and C. However, they are fairly different from the EAV-UCD strain. Nevertheless, the nucleotide and amino acid differences observed among the Argentine strains LP02/R, LP02/C, LP02/P and LP-LT-ARG did not show any variations in the neutralization phenotype.La arteritis viral equina (AVE ocasiona infecciones, en su mayoría subclínicas, pero puede causar abortos y enfermedad respiratoria.

    In September 1999, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), with assistance from the New Brunswick Laboratory (NBL) of the U.S. Department of Energy, started a new cooperative activity with, among other objectives, the production and characterization of a traceable uranium secondary standard and the performance of the Third Round Robin for ABACC's laboratory network. Brazil and Argentina have fabricated UO 2 pellets for use as a secondary standard. Samples from the two batches were sent to NBL for the determination of the reference values for both uranium concentration (%U) and isotopic composition for each batch. ABACC and NBL then organized the Third ABACC Round Robin for Brazilian and Argentine laboratories that are part of the ABACC network. The laboratories comprising the network can be used to analyze real samples collected during the ABACC inspections. The Brazilian and Argentine pellets were distributed to all the laboratories together with the protocol to be followed for the uranium concentration analysis, the forms for reporting the measurement results, and natural UO 2 pellets (CETAMA OU1) to be used as reference material. For the laboratories with capability of measuring isotopics, NBL reference material CRM 125-A was provided. Several laboratories from each country provided results. As soon as the measurement results were sent to the organizers, they were statistically evaluated by NBL. During a meeting held at ABACC headquarters with the participation of NBL representatives, the ABACC technical support officer, and representatives of all the participant laboratories, the results were discussed and compared with the reference values. All the laboratories had the occasion, in an open discussion, to explain and show the difficulties and problems they faced during the exercise. ABACC had the opportunity not only to judge the quality of the measurements these laboratories performed, but also to determine

Here we identify different mutations of CFTR and the poly-T variant of intron 8 (IVS8 in Argentine patients and analyze sweat test values and clinical characteristic related to Cystic Fibrosis (CF. For counseling purposes the two most frequent mutations in Argentine CF population: DF508 and G542X were screened in wives. In all cases, it was possible to reduce the risk of CF/CBAVD descendants in these couples because none of the mutation were found in the 36 samples. Eight patients (23% showed abnormal chloride values (> 60 mmol/l. A second group of 6 patients (18% had borderline values of sweat chloride (40-59 mmol/l. We defined another group with 6 patients (18%, with normal sweat chloride levels (30-39 mmo/l and a fourth group of 14 (41% patients with sweat chloride below 30 mmol/l. DF508, the most frequent CF mutation in the Argentine population, was found on 15 of the 72 chromosomes (21%, R117H mutation was detected on 2 of 62 chromosomes (3%. Only one R347P allele was found on 28 chromosomes analyzed (2%. On a sample of 27 patients, IVS8 analysis showed a frequency of 6/56 chromosomes (11% of 5T allele.

    Full Text Available This article examines the critical role played by social identity in the construction of hospitals in the Argentine health care sector during the 1940s and 1950s by uncovering the way in which the “jungle” of hospitals withstood attempts by the state to apply some sense of order, purpose, and centralized organization. The first section examines how physicians envisioned the “modern” hospital they hoped to construct. The second section reveals the important antecedents of nationalized hospitalization schemes found in the collaboration between physicians’ unions and the state. In the third section, an analysis of political speeches illuminates how Juan and Evita Perón packaged new hospitals as gifts to the people from their leader. The fourth section outlines specific plans to increase the number of hospital beds. The final section surveys examples of hospital construction to demonstrate how sub-national identities were instrumental to fragmenting both Argentine society and its hospital infrastructure.

    Full Text Available Agricultural intensification in rural areas of developing countries compromises the provision of ecosystem services. Social conflict arises among landholders with different preferences for ecosystem services and land-use practices in agricultural frontiers of the Argentine Dry Chaco. We explored policy and management options by assessing the actual and potential outcomes of alternative land-use systems and scenarios. We first constructed the efficiency frontier for avian habitat and agricultural productivity to analyze the combinations of ecosystem services that can be achieved under different land-use intensities. A nonlinear, concave efficiency frontier indicated opportunities to achieve large gains for production with small losses for conservation, for instance, by transitioning from low- to intermediate-intensity systems. Second, we projected production and conservation outcomes, which can be achieved through the implementation of five alternative policy options. The land sharing with conservation scenario, 70% of the landscape covered by intermediate-intensity systems and 30% by undisturbed forests, yielded the higher combination of avian habitat and agricultural productivity. Third, we constructed indifference curves of three landholder groups, i.e., preproductivist, multifunctional, and productivist, by assessing their intentions (proxies for preferences to conserve and convert remnant forests in their landholdings. Multifunctional landholders showed balanced preferences for conserving and converting forests in their landholdings, and maintaining intermediate-intensity systems. A general willingness to conserve forests coexisted in preproductivist landholders with the intention to clear some portions of the landholding and intensify landuse, indicating the potential of an endogenously motivated transition toward a multifunctional regime. Such transition may increase their productivity by 35-65% without compromising avian habitat

    Full Text Available Almost since its publication, Don Quixote had an attractive magnetism in writers from different languages and different times, who imitated, continued and rewroted the Cervantes’s best literary work. Argentine is possibly the american country that most has contributed to increased this literary heritage. Contemporary to the famous «Pierre Menard, autor del Quijote» published by Jorge Luis Borges in 1939 and 1941 (perhaps the paradigmatic rewriting of a Cervantine text in the argentine literature will rise an original and unclasificable text: a political satire of the argentine reality of the River Plate, looking for an argentine identity. This work is El nuevo gobierno de Sancho, published by the Jesuit Leonardo Castellani in 1942. The purpose of this article is to do a comparative study with Don Quixote.

    Understanding the complex epidemiology of Trypanosoma cruzi transmission cycles requires comparative studies in widely different environments. We assessed the occurrence of T. cruzi infection in sylvatic mammals, their infectiousness to the vector, and parasite genotypes in a protected area of the Argentine Chaco, and compared them with information obtained similarly in a nearby disturbed area. A total of 278 mammals from >23 species in the protected area were diagnosed for T. cruzi infection using xenodiagnosis, kDNA-PCR and nuclear satellite DNA-PCR (SAT) from blood samples. The relative abundance and species composition differed substantially between areas. Didelphis albiventris opossums were less abundant in the protected area; had a significantly lower body mass index, and a stage structure biased toward earlier stages. The capture of armadillos was lower in the protected area. The composite prevalence of T. cruzi infection across host species was significantly lower in the protected area (11.1%) than in the disturbed area (22.1%), and heterogeneous across species groups. The prevalence of infection in D. albiventris and Thylamys pusilla opossums was significantly lower in the protected area (nil for D. albiventris), whereas infection in sigmodontine rodents was three times higher in the protected area (17.5 versus 5.7%). Parasite isolates from the two xenodiagnosis-positive mammals (1 Dasypus novemcinctus and 1 Conepatus chinga) were typed as TcIII; both specimens were highly infectious to Triatoma infestans. Fat-tailed opossums, bats and rodents were kDNA-PCR-positive and xenodiagnosis-negative. Desmodus rotundus and Myotis bats were found infected with T. cruzi for the first time in the Gran Chaco.

  1. The effects of nitric oxide cooling and the photodissociation of molecular oxygen on the thermosphere/ionosphere system over the Argentine Islands

    1997-03-01

    Full Text Available In the past the global, fully coupled, time-dependent mathematical model of the Earth's thermosphere/ionosphere/plasmasphere (CTIP has been unable to reproduce accurately observed values of the maximum plasma frequency, foF2, at extreme geophysical locations such as the Argentine Islands during the summer solstice where the ionosphere remains in sunlight throughout the day. This is probably because the seasonal dependence of thermospheric cooling by 5.3 µm nitric oxide has been neglected and the photodissociation of O2 and heating rate calculations have been over-simplified. Now we have included an up-to-date calculation of the solar EUV and UV thermospheric heating rate, coupled with a new calculation of a diurnally varying O2 photodissociation rate, in the model. Seasonally dependent 5.3 µm nitric oxide cooling is also included. With these important improvements, it is found that model values of foF2 are in substantially better agreement with observation. The height of the F2-peak is reduced throughout the day, but remains within acceptable limits of values derived from observation, except at around 0600 h LT. We also carry out two studies of the sensitivity of the upper atmosphere to changes in the magnitude of nitric oxide cooling and photodissociation rates. We find that hmF2 increases with increased heating, whilst foF2 falls. The converse is true for an increase in the cooling rate. Similarly increasing the photodissociation rate increases both hmF2 and foF2. These changes are explained in terms of changes in the neutral temperature, composition and neutral wind.

Este trabajo analiza el tipo de tratamiento que recibió el llamado «caso Píparo» a través de un análisis de contenido exploratorio e inductivo de la cobertura que los diarios Clarín y La Nación dieron al tema. El objetivo es elaborar un libro de códigos que pueda ser validado en estudios de casos similares mediante el análisis de contenido de la prensa gráfica.

This case outraged the public opinion because she was eight months pregnant at the moment of the assault. She had to undergo a caesarean section and her baby only survived one week. Through an exploratory and inductive research we will analyze how the Argentine newspapers presented the case. We aim at elaborating a content analysis code book that can be validated in future similar researches on the subject. We apply the Framing theory in order to detect the frames used in the news coverage and to observe if they are compatible with the idea of «moral panic» proposed by Stanley Cohen.

    The United States Department of Energy (DOE), as well as international atomic energy commission, facilities use ion exchange materials for purification of aqueous streams in the nuclear industry. Unfortunately, the use of the ion exchange materials creates a waste stream that can be very high in both organic and radioactive constituents. Therefore, disposal of the spent resins often becomes an economic problem because of the large volumes of resin produced and the relatively few technologies that are capable of economically stabilizing this waste. Vitrification of this waste stream presents a reasonable disposable alternative because of its inherent destruction capabilities, the volume reductions obtainable, and the durable product that it produces

    The threat of invasive species is often intensified in disturbed habitat. To optimize control programs, it is necessary to understand how degraded habitat influences the behavior of invasive species. We conducted a radio telemetry study to characterize movement and habitat use of introduced male Argentine black and white tegus (Tupinambis merianae) in the Everglades of southern Florida from May to August 2012 at the core and periphery of the introduced range. Tegus at the periphery moved farther per day (mean 131.7 ± 11.6 m, n = 6) compared to tegus at the core (mean 50.3 ± 12.4 m, n = 6). However, activity ranges were not significantly smaller in the core (mean 19.4 ± 8.4 ha, n = 6) compared to periphery (mean 29.1 ± 5.2 ha, n = 6). Peripheral activity ranges were more linear due to activity being largely restricted to levee habitat surrounded by open water or marsh. Tegus were located in shrub or tree habitat (mean 96%) more often than expected based on random locations (mean 58%), and the percent cover of trees and shrubs was higher in activity ranges (mean 61%) than the general study area (17%). Our study highlighted the ability of tegus to spread across the Florida landscape, especially in linear disturbed habitats where increased movement occurred and in areas of altered hydrology where movement is not restricted by water.

    Full Text Available Argentina is among the four largest producers of soybeans, sunflower, corn, and wheat, among other agricultural products. Institutional and policy changes during the 1990s fostered the development of Argentine agriculture and the introduction of innovative process and product technologies (no-till, agrochemicals, GMO, GPS and new investments in modern, large-scale sunflower and soybean processing plants. In addition to technological changes, a "quiet revolution" occurred in the way agricultural production was carried out and organized: from self-production or ownership agriculture to a contract-based agriculture. The objective of this paper is to explore and describe the emergence of networks in the Argentine crop production sector. The paper presents and describes four cases that currently represent about 50% of total grain and oilseed production in Argentina: "informal hybrid form", "agricultural trust fund", "investor-oriented corporate structure", and "network of networks". In all cases, hybrid forms involve a group of actors linked by common objectives, mainly to gain scale, share resources, and improve the profitability of the business. Informal contracts seem to be the most common way of organizing the agriculture process, but using short-term contracts and sequential interfirm collaboration. Networks of networks involve long-term relationships and social development, and reciprocal interfirm collaboration. Agricultural trust fund and investor-oriented corporate structures have combined interfirm collaboration and medium-term relationships. These organizational forms are highly flexible and show a great capacity to adapt to challenges; they are competitive because they enjoy aligned incentives, flexibility, and adaptability.La Argentina está entre los cuatro mayores productores mundiales de soja, girasol, maíz y trigo, entre otros productos agrícolas.

    Community-based management (CBM) has been recognized as an appropriate approach to conservation, assuming that local communities have higher stakes than the state in their natural resources and have better knowledge of local resources and, therefore, can manage them more efficiently. However, the implementation of CBM has not always been successful. The objective of this research was to assess the potential for the implementation of a governmental proposal for community-based management of peccaries (Tayassuidae) in the Impenetrable northern Argentine, through the examination of the reasons why arrangements to avoid overexploitation have not evolved in this region. I used the theory of common pool resources (CPRs) as a framework for this analysis. CPRs theory explains the conditions under which appropriators of a resource are likely to engage in devising and altering governing arrangements and the conditions under which such arrangements are likely to succeed. Fieldwork was conducted between June 2000 and August 2003 using a mixed methods approach. It was found that most of the condition of the resource and users identified by the CPR theory as associated with an increased likelihood of successful management of natural resources are absent or scarcely developed in the Impenetrable. Thus, the situation in the Impenetrable does not seem appropriate for the implementation of CBM of peccaries. It is first necessary to invest in training and development of local institutions' capacities and social capital. It is also important to increase the flow of relevant information, which will enable institutions to be effective, responsible, and accountable to the community. For the moment, a more appropriate approach will have to include a mixture of protectionism and comanagement of collared peccaries while the propitious conditions for a complete local management of the resource are developed.

  10. Favipiravir (T-705 inhibits Junín virus infection and reduces mortality in a guinea pig model of Argentine hemorrhagic fever.

    Full Text Available Junín virus (JUNV, the etiologic agent of Argentine hemorrhagic fever (AHF, is classified by the NIAID and CDC as a Category A priority pathogen. Presently, antiviral therapy for AHF is limited to immune plasma, which is readily available only in the endemic regions of Argentina. T-705 (favipiravir is a broadly active small molecule RNA-dependent RNA polymerase inhibitor presently in clinical evaluation for the treatment of influenza. We have previously reported on the in vitro activity of favipiravir against several strains of JUNV and other pathogenic New World arenaviruses.To evaluate the efficacy of favipiravir in vivo, guinea pigs were challenged with the pathogenic Romero strain of JUNV, and then treated twice daily for two weeks with oral or intraperitoneal (i.p. favipiravir (300 mg/kg/day starting 1-2 days post-infection. Although only 20% of animals treated orally with favipiravir survived the lethal challenge dose, those that succumbed survived considerably longer than guinea pigs treated with placebo. Consistent with pharmacokinetic analysis that showed greater plasma levels of favipiravir in animals dosed by i.p. injection, i.p. treatment resulted in a substantially higher level of protection (78% survival. Survival in guinea pigs treated with ribavirin was in the range of 33-40%. Favipiravir treatment resulted in undetectable levels of serum and tissue viral titers and prevented the prominent thrombocytopenia and leucopenia observed in placebo-treated animals during the acute phase of infection.The remarkable protection afforded by i.p. favipiravir intervention beginning 2 days after challenge is the highest ever reported for a small molecule antiviral in the difficult to treat guinea pig JUNV challenge model. These findings support the continued development of favipiravir as a promising antiviral against JUNV and other related arenaviruses.

    Within the framework of the RERTR Program and supported by the technical cooperation work agreed upon between the U.S.A. and Argentina in May 1979, the CNEA Nuclear Fuel Department - Low Enriched Fuel Elements Project (ECBE Project), has carried on its own program for developing fuels with low enrichment for research and test reactors. Up to the present, its main objective has been to replace the highly enriched fuel used in its only reactor (RA-3) for research, development and radioisotopes production. The basic stages of the Argentine Program are shown in Table 1. At a meeting held in Vienna in March, 1980, the CNEA stated that its development of fuels with low enrichment would be in two fuel lines: UAl x -Al and U 3 O 8 -Al, and that its aim would be to reach uranium densities of 18-2.2 g/cm 3 for the UAI x -Al line and 2.4-3.0 g/cm 3 for the U 3 O 8 line. At the international meeting held at ANL in November, 1980, and after having received depleted uranium and uranium with 20% and 45% enrichment (purchased from the U.S.A. for manufacturing miniplates and possible standard fuels) to carry on the proposed development, CNEA anticipated -- after its first tests -- that the conditions were satisfactory for reaching uranium densities of 2.4-3.0 g/cm 3 in U 3 O 8 -Al fuel and of 2.4 g/cm 3 in UAI x -Al fuel. In February 1981, after Argentina accepted the obligation of paying for the irradiation service, authorization was obtained for irradiating miniplates in the Oak Ridge Reactor within the RERTR Program. In June 1981, the first set of miniplates was sent to Oak Ridge National Laboratory (ORNL). The maximum actual densities reached at that time were 3.12 g/cm 3 with U 3 O 8 -Al and 2.52 g/cm 3 with UAl x -Al. During a visit of the CNEA Project Technical Manager to the Argonne National Laboratory (ANL) in July 1981, and after exchanging ideas with ANL professional staff, the CNEA decided to incorporate a new line of development, that of U 3 Si-Al. Three months later

    now reconsidered for organ transplantation. In 2008, the Argentine Society of Transplants (SAT and the Argentine Infectious Diseases Society (SADI, encouraged by the increasing published experience on kidney and liver transplants in this population, decided to form a Working Group, to prepare an update on this issue and elaborate practical recommendations for the better management of these patients. The first meeting was held on December 4th 2008. The most important conclusion was that HIV infection did not contraindicate a solid organ transplant. Later on, taking into account the accumulated experience and the available literature, the current document was prepared. HIV infected patients must fulfill certain clinical, immunological, virological and psychosocial criteria to be considered for solid organ transplants. HIV infected recipients of kidney and liver transplants currently show similar short and middle term survival to non HIV infected patients. There is not yet enough data on intrathoracic transplants in these patients in order to include them on a waiting list for these organs-transplants. Interactions between immunosupressors and antiretroviral drugs (specially protease inhibitors are very important, and require a strict monitoring of immunosupressor levels.

    The Argentine Republic has extensive antecedents in education and training in radiological protection. From the beginning of the nuclear activity in the country was given preponderance to the aspects related with the radiological protection and the personnel's training involved in the employment of ionizing radiations. At the present time these educational activities already overcome the 50 years, there being accumulated a rich and important experience in the matter. In the country the organisms that have assigned by law the responsibility of the regulation and the control of practice them with ionizing radiations are the Nuclear Regulatory Authority and the Ministry of Health and Atmosphere of the Nation. The first one has the mission of protecting people of the noxious effects of the ionizing radiations derived of nuclear activities, the second is in charge of the control of the equipment dedicated specifically to generate X-rays. This includes the responsibility of elaborating, to emit and to make complete the regulations, standards and other corresponding requirements, in particular - in the mark of the present work - regarding to establish demands and to promote education activities and training in radiological protection. The sure use of the benefits that offers the nuclear development in its diverse applications implies to overturn resources, experience and dedication for the personnel's training. In that sense the Argentina has committed recently to undertake the necessary actions to constitute a Regional Center of Education and Training for Latin America and the Caribbean, taking advantage of the important experience obtained in more of 25 years of imparting graduate degree courses in radiological protection and nuclear safety with inter regional and regional character. With that purpose a process of self evaluation has begun (self appraisal), following the limits settled down by the International Atomic Energy Agency in the document &apos

    Industrial gammagraphy has always been responsible for the highest rates of radiological incidents in almost every part of the world. This is mainly due to the high activities of the radioactive sources used, which are constantly transported in the equipment that contains them between the storage and the areas of work, and is also due to workload pressures which may induce to negligence in following the operational procedures, if a strong Safety Culture does not exist. The purpose of this paper is to present the main aspects of the Argentine Regulations relating to radiation protection to control this practice and to contribute in this way to reduce the associated risks. In addition, some incidents occurred in Argentina during the latest years, the causes that led to those events and their relation to the in observance of the regulations in force, their consequences and the measures taken to repair them are described. Finally, the importance of the role that education and training has in the strengthening of Safety Culture, key element of all undertaking, is highlighted. (author) [Spanish] La gammagrafia industrial siempre fue responsable de los mayores indices de accidentes radiologicos en casi todo el mundo. Esto se debe principalmente a las altas actividades de las fuentes radiactivas utilizadas, las cuales son transportadas constantemente en los equipos que las contienen entre el deposito y las areas de trabajo, y a presiones de carga de trabajo que pueden inducir a descuidos en el seguimiento de los procedimientos de operacion, si no existe una Cultura de la Seguridad arraigada. El proposito de este trabajo es presentar los aspectos principales de la reglamentacion argentina en materia de radioproteccion para controlar esta practica y de esta manera contribuir a reducir los riesgos asociados. Asimismo, se describen algunos incidentes ocurridos en argentina durante los ultimos anios, las causas que condujeron a dichos sucesos y su relacion con el incumplimiento

    Full Text Available OBJETIVO: Desarrollar referencias nuevas y mejoradas de peso al nacer según la edad gestacional (EG, el sexo y la multiplicidad del parto, para la población argentina en su conjunto. MÉTODOS: La población de estudio incluyó a todos los nacidos vivos de partos simples (n = 3 478 286 y dobles (n = 57 654 en Argentina durante el período 2003-2007. Los probables errores en la clasificación de la EG basada en la fecha de la última menstruación fueron corregidos con el uso de modelos de distribuciones normales mixtas. Los percentiles se obtuvieron mediante la regresión de cuantiles, que además posibilitó el suavizamiento de las curvas. RESULTADOS: Se obtuvieron curvas de peso al nacer para partos simples entre las semanas 22 y 43 de gestación y para partos dobles entre las semanas 24 y 41, según el sexo del neonato. Comparadas con estudios previos, estas referencias no sobreestiman la proporción de nacidos vivos grandes para su EG. Se observó también un aumento del peso al nacer a lo largo del período de estudio. CONCLUSIONES: Las curvas propuestas tienen las ventajas de basarse en grandes números, de ser representativas de los nacimientos argentinos más recientes, de distinguir el tipo de parto y el sexo de los neonatos, y de minimizar los errores de clasificación de la EG. Constituyen por lo tanto una herramienta útil para medir desigualdades y así identificar grupos poblacionales con mayor riesgo de eventos perinatales adversos.OBJECTIVE: To develop new and improved reference birthweights for the Argentine population as a whole with a breakdown by gestational age (GA, sex and multiplicity of birth.

    Through time, anaerobic bacteria have shown good susceptibility to clinically useful antianaerobic agents. Nevertheless, the antimicrobial resistance profile of most of the anaerobic species related to severe infections in humans has been modified in the last years and different kinds of resistance to the most active agents have emerged, making their effectiveness less predictable. With the aim of finding an answer and for the purpose of facilitating the detection of anaerobic antimicrobial resistance, the Anaerobic Subcommittee of the Asociación Argentina de Microbiología developed the First Argentine consensus guidelines for in vitro antimicrobial susceptibility testing of clinically relevant anaerobic bacteria in humans. This document resulted from the compatibilization of the Clinical and Laboratory Standards Institute recommendations, the international literature and the work and experience of the Subcommittee. The Consensus document provides a brief taxonomy review, and exposes why and when anaerobic antimicrobial susceptibility tests should be conducted, and which antimicrobial agents can be used according to the species involved. The recommendations on how to perform, read and interpret in vitro anaerobic antimicrobial susceptibility tests with each method are exposed. Finally, the antibiotic susceptibility profile, the classification of antibiotics according to their in vitro activities, the natural and acquired mechanisms of resistance, the emerging resistance and the regional antibiotic resistance profile of clinically relevant anaerobic species are shown.

    Toxicity and the utilization of venom are essential features in the ecology of many animal species and have been hypothesized to be important factors contributing to the assembly of communities through competitive interactions. Ants of the genus Monomorium utilize a variety of venom compositions, which have been reported to give them a competitive advantage. Here, we investigate two pairs of Monomorium species, which differ in the structural compositions of their venom and their co-occurrence patterns with the invasive Argentine ant. We looked at the effects of Monomorium venom toxicity, venom utilization, and aggressive physical interactions on Monomorium and Argentine ant survival rates during arena trials. The venom toxicity of the two species co-occurring with the invasive Argentine ants was found to be significantly higher than the toxicity of the two species which do not. There was no correlation between venom toxicity and Monomorium survival; however, three of the four Monomorium species displayed significant variability in their venom usage which was associated with the number of Argentine ant workers encountered during trials. Average Monomorium mortality varied significantly between species, and in Monomorium smithii and Monomorium antipodum, aggressive interactions with Argentine ants had a significant negative effect on their mortality. Our study demonstrates that different factors and strategies can contribute to the ability of a species to withstand the pressure of a dominant invader at high abundance, and venom chemistry appears to be only one of several strategies utilized.

  10. Reproductive Rights or Reproductive Justice? Lessons from Argentina.

    Science.gov (United States)

    Morgan, Lynn

    2015-06-11

    Argentine sexual and reproductive rights activists insist on using the language and framework of "human rights," even when many reproductive rights activists in the US and elsewhere now prefer the framework of "reproductive justice." Reflecting on conversations with Argentine feminist anthropologists, social scientists, and reproductive rights activists, this paper analyzes why the Argentine movement to legalize abortion relies on the contested concept of human rights. Its conclusion that "women's rights are human rights" is a powerful claim in post-dictatorship politics where abortion is not yet legal and the full scope of women's rights has yet to be included in the government's human rights agenda. Argentine feminist human rights activists have long been attentive to the ways that social class, gender, migration, and racism intersect with reproduction. Because their government respects and responds to a human rights framework, however, they have not felt it necessary--as U.S. feminists have--to invent a new notion of reproductive justice in order to be heard. Given the increasing popularity of reproductive justice in health and human rights, the Argentine case shows that rights-based claims can still be politically useful when a State values the concept of human rights.

    This is the final work to obtain a Diploma on Specialization in Application of Nuclear Technological Energy, carried out at the Research Reactor RA-6, from March to December 1999. Different work has been realized on the Tangential Tube N of the 500 KW Argentine RA-6 research reactor, in order to add a new technique to the present existing analytical methods. This Prompt Gamma Neutron Activation Analysis technique (PGNAA) requires a beam of collimated thermal neutrons, a lowest possible gamma radiation, and a thermal component of the biggest possible cadmium rate. It also must have a high resolution detection system for the measurement of the gamma radiation emitted after the capture of the neutron produced in the study sample. Continuing with the facility's technical requirements, a collimator was installed inside the N passing tube, in order to concentrate the neutrons coming from the nuclear core and also to compensate possible losses during the path. This collimator is 440mm long and 200 mm in diameter and consists of lead and steel cylinders with different size holes on the inside, so that it can deliver a 50 mm diameter beam of thermal collimated neutrons. Two 100 mm thick bismuth filters are inside the passing tube, to reduce the gamma component inside de beam, coming from the reactor core. This work aims to the characterization of the thermal and epithermal component of the neutron beam in the collimator and at the exit of it , and also to prove experimentally that the collimator achieves the technical specifications for which it was designed and built, specifically by verifying its functioning (degree of convergence of the beam obtained). On the other hand, it is necessary to learn about the PGNAA technique in order to define the technical requirements for its adequate operation. (author)

    Single-rod burst tests were performed with Atucha I Zircaloy-4 cladding tubes in the REBEKA burst equipment of KfK. The objective was to investigate the ballooning and burst behavior of argentine cladding tubes obtained from NRG, Germany and CONVAR, Argentina. The burst data were compared with those of cladding tubes used in german PWR's. It was found that the burst data e.g. burst temperature, circumferential burst strain and its response to azimuthal temperature differences are identical for the Argentine and German tubing quality. The burst data are in good agreement with those of German PWR-Zircaloy tubes. Thus, the fuel rod behavior codes developed for German PWR's can also be used for the Argentine reactor Atucha I. (orig.)

    In June 1998, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), with assistance from the U.S. Department of Energy (DOE), began a program to assess environmental sampling and analysis capabilities at laboratories in Argentina and Brazil. The program began with staff training conducted in South America and the United States by Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL). Both laboratories are participating members of DOE's Network of Analytical Laboratories (NWAL) that support IAEA's environmental sampling program. During the initial planning meeting, representatives from ABACC and all the participating analytical laboratories supporting ABACC were briefed on how the first exercise would be managed and on key aspects necessary to analyze low-level environmental samples for uranium. Subsequent to this training, a laboratory evaluation exercise (Exercise 1) was conducted using standard swipe samples prepared for this exercise by the International Atomic Energy Agency (IAEA). The results of Exercise 1 determined that sample contamination was a major factor in the analysis, and a thorough review of laboratory procedures was required to reduce the level of contamination to acceptable levels. Following modification of sample preparation procedures, the laboratories performed Exercise 2, an analysis of a National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 1547, Peach Leaves. The results of Exercise 2 demonstrated that several laboratories were capable of accurately determining the total uranium and uranium isotopic distribution in the peach leaves. To build on these successes, Exercise 3 was performed using a series of standard swipe samples prepared by the IAEA and distributed to laboratories supporting ABACC and to PNNL and ORNL. The results of Exercise 3 demonstrate that ABACC now has support laboratories in both Argentina and Brazil, which are capable of

    ública.Cet article a pour objectif d'analyser l'influence de la crise économique sur la formation de nouvelles coalitions politique dans l'Argentine des années 2000, qui ont mené à la rupture de la politique économique adoptée par les gouvernements Menem et De la Rúa. Ces transformations ont favorisé un changement dans la stratégie du gouvernement Néstor Kirchner concernant les relations avec le Fonds Monétaire International (FMI, ce qui a engendré une position plus dure de la part du gouvernement argentin et un rejet des positions du FMI. La politique économique soutenue par les gouvernements Duhalde et Kirchner s'est appuyée sur le régime de change compétitif, à la place du régime de conversion en vigueur dans les années 1990, et comptait sur l'appui des groupes d'entrepreneurs orientés vers le marché domestique, mieux lotis en fonction de la dévalorisation du « peso ». La proposition de ces gouvernements pour la relance économique a supprimé des acteurs ayant des liens étrangers, qui participaient à des coalitions d'appui sous Menem et De la Rúa. Parmi les exclus, figuraient les créanciers ayant des papiers de la dette en moratoire depuis 2001 et les entreprises offrant des services publics qui avaient été privatisées dans les années 1990 et qui ont reçu appui du FMI. Ces raisons expliquent le fait que les négociations avec le Fonds pendant le gouvernement Kirchner ont été marquées par des impasses et par l'attitude énergique de la part des négociateurs argentins. Des transformations dans le contexte international ont également eu des impacts sur les négociations du gouvernement Kirchner avec le FMI. Avec l'élections de George W.Bush aux États-Unis, en 2000, l'appui nord-américain à la concession d'emprunts du Fonds à des pays en développement s'est affaibli. Le gouvernement républicain a encore prôné la réduction du rôle du FMI dans l'intermédiation des négocitions entre les pays endettés et les créanciers privés. Ainsi

    This article discusses the effects of the alliance between the Church and the Argentine state on women's reproductive rights. Several commentators have criticized how President Carlos Menem used the campaign against abortion for his own political interest. He issued a presidential decree on antiabortion campaign--the Day of the Unborn Child. This decree was announced on December 8, 1998, and the day of observance is March 25 of every coming year. Although the Argentine government does not have a law that explicitly regulates family planning method for the last two decades, many Argentines find the action of the president selfish. The initiation of this presidential decree was the culmination of Menem's manipulation of church and state to secure clerical support for his political regime. Even if statistics is providing him with data concerning the effects of unclear reproductive health laws, he and the church still has chosen not to focus on reproductive rights exclusively, but have concerned themselves primarily with other social and economic issues. While Menem uses the Vatican's pro-life rhetoric and his presidential power to protect fetal life, Argentines will have to contend with the existing Menem policies, which compromise the health of women and children.

    The continuous emergence of new strains of canine parvovirus (CPV), poorly protected by current vaccination, is a concern among breeders, veterinarians, and dog owners around the world. Therefore, the understanding of the genetic variation in emerging CPV strains is crucial for the design of disease control strategies, including vaccines. In this paper, we obtained the sequences of the full-length gene encoding for the main capsid protein (VP2) of 11 canine parvovirus type 2 (CPV-2) Argentine representative field strains, selected from a total of 75 positive samples studied in our laboratory in the last 9 years. A comparative sequence analysis was performed on 9 CPV-2c, one CPV-2a, and one CPV-2b Argentine strains with respect to international strains reported in the GenBank database. In agreement with previous reports, a high degree of identity was found among CPV-2c Argentine strains (99.6-100% and 99.7-100% at nucleotide and amino acid levels, respectively). However, the appearance of a new substitution in the 440 position (T440A) in four CPV-2c Argentine strains obtained after the year 2009 gives support to the variability observed for this position located within the VP2, three-fold spike. This is the first report on the genetic characterization of the full-length VP2 gene of emerging CPV strains in South America and shows that all the Argentine CPV-2c isolates cluster together with European and North American CPV-2c strains.

    An audit was carried out by the Argentine Nuclear Regulatory Authority to verify regulations and safe working procedures compliance by registrants authorized for use of radiation sources in well logging. A task force based on four inspection teams was organized. The audit was carried out at registrant's premises (equipment storage facilities) simultaneously. The evaluation was based on a system allowing a fast qualification of both, potential problems identified and their solutions. The results show that 95 % of the inspected locations were classified under the 'acceptable', 'good' and 'very good' headings. (author)

    Full Text Available Through a consultation of the literature written by the most important authors in argentine tango history and theory and through the testimonials of some renowned tango dancers and teachers of today, argentine tango is being examined from a technical and executive point of view with the goal to give an explanation to the questions that arise around its authentic aesthetical image and during its concrete realization on the dance floor. After a careful presentation of the rules that determine tango and the frame where the momentary creative expression takes place, a specific attention is dedicated to the notions of corte and quebrada. These elements are considered of fundamental importance in the choreographic construction that is being created by improvisation and in the definition of the argentine tango aesthetical and technical identity.

    In Argentine, comprehensive noise measurements have been performed with the reactor instrumentation of the PHWR power plant Atucha I and Embalse. The Embalse reactor is a CANDU-600 (600 Mwe) type pressurized heavy water reactor. It's a heavy water moderator and heavy water cooled natural uranium fueled pressure tube system. Signal of vanadium and platinum type in core-self power neutron detectors of ex-core ion chambers and of a moderator pressure sensor have been recorded and analysed. The vibration of reactor internals as vertical and horizontal in-core neutron flux detectors units and the coolant channels systems, consisting of calandria and pressure tubes with fuel bundles, have been identified and monitored during normal reactor operation. Atucha I, is a PHWR reactor natural uranium fueled, and heavy water moderated and cooled. Neutron noise techniques using of ex-core ionization chambers and in-core Vanadium SPND's were implemented, among others, in order to produce early detection of anomalous vibrations in the reactor internals. Noise analysis was successfully performed to identify normal and peculiar vibrations in particular reactor internals. (author)

    Bottom currents and their margin-shaping character became a central aspect in the research field of sediment dynamics and paleoceanography during the last decades due to their potential to form large contourite depositional systems (CDS), consisting of both erosive and depositional features. A major CDS at the northern Argentine continental margin was studied off the Rio de la Plata River by means of seismo- and hydro-acoustic methods including conventional and high-resolution seismic, parametric echosounder and single and swath bathymetry. Additionally, hydrographic data were considered allowing jointly interpretation of morphosedimentary features and the oceanographic framework, which is dominated by the presence of the dynamic and highly variable Brazil-Malvinas Confluence. We focus on three regional contouritic terraces identified on the slope in the vicinity of the Mar del Plata Canyon. The shallowest one, the La Plata Terrace (˜500 m), is located at the Brazil Current/Antarctic Intermediate Water interface characterized by its deep and distinct thermocline. In ˜1200 m water depth the Ewing Terrace correlates with the Antarctic Intermediate Water/Upper Circumpolar Deep Water interface. At the foot of the slope in ˜3500 m the Necochea Terrace marks the transition between Lower Circumpolar Deep Water and Antarctic Bottom Water during glacial times. Based on these correlations, a comprehensive conceptual model is proposed, in which the onset and evolution of contourite terraces is controlled by short- and long-term variations of water mass interfaces. We suggest that the terrace genesis is strongly connected to the turbulent current pattern typical for water mass interfaces. Furthermore, the erosive processes necessary for terrace formation are probably enhanced due to internal waves, which are generated along strong density gradients typical for water mass interfaces. The terraces widen through time due to locally focused, partly helical currents along the

    'American foulbrood' is a disease that seriously affects bees. Honey may be contaminated with spores of the related bacteria, Paenibacillus larvae larvae, which is a great drawback for trade. The scientific literature reports that these spores, resistant to heat and chemicals, are inactivated in honey when it is irradiated al 10 kGy, being this treatment mandatory in the Republic of Southafrica. Irradiated food wholesomeness is endorsed by the World Health Organization. Considering that Argentina is an important honey producer and exporter, the aim of this work was to evaluate the effect of ionizing radiation on some of its commercial chemical parameters along storage time. Honeys with different characteristics, coming from five different regions of the country: Middle, Patagonia, North, Litoral, Humid Pampa, were provided by producers from a commission called 'Packaged honey' of the National Food, Fishery and Agriculture Ministry. Fifteen kg of each honey variety were packaged in 500 g polypropylene recipes with polyethylene lids, and irradiated at the semi industrial cobalt-60 facility of the Ezeiza Atomic Center, 500,000 Ci of activity, with doses of 0, 10 and 20 kilo Grays. Control and irradiated samples were stored at room temperature for 10 months. Some standardized chemical analysis required by the Argentine Food Code (AFC) were performed on the first, fourth and tenth storage months: water content, acidity, diastase content, reducing sugars, and hydroxymethylfurfural. Reducing sugars and diastase activity slightly diminished, and acidity slightly increased, along storage which is typical in this product; no significant differences were found between control and irradiated samples. Hydroxymethylfurfural values, related to aging or thermal abuse, diminished slightly though significantly due to irradiation, which would not affect the product quality as regulations require not to surpass a maximum value, 40 mg/kg in the AFC. So ionizing irradiation at a 10 k

    With the exception of Hollywood films, there has been no more intense point of cultural contact between Argentina and the United States than boxing. This article considers two intertwined topics. The first is the construction of the imagery of Argentine boxers in the United States and the varieties of Argentine boxers’ immigrant experience in North America. Second, this article will argue that the presence of Argentine boxers in the United States forged a sense in Argentina that the former were leading actors on the American boxing scene. This, in turn, shaped Argentine boxing cultures and self images.

  1. Research reactors in Argentina

    1999-01-01

    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

    2014-06-01

    Taking into account recent studies on journalistic travel and Argentine nation building, this article examines the profile of a type of reporter that has been studied to a lesser degree, the immigrant journalist. It analyzes two travel chronicles about Patagonia published in Buenos Aires in 1898: Ein Ausflug nach dem Chubut-Territorium [An Excursion to the Chubut Territory] by Swiss journalist Theodor Alemann, published in the German-language newspaper Argentinisches Tageblatt [Argentine Daily], and La australia argentina, by Roberto J. Payró which appeared in La Nación. In both chronicles the narration of the trip to Patagonia is interrupted at a key moment by the telling of a dream regarding the future of the region. This essay demonstrates that these oneiric digressions reveal political and economic interests contrary to the official Argentine plans for the development of the region, the role of immigrants and their relationship with European powers.

    Felizia, Eduardo R.

    2005-01-01

    This report describes some of the regulatory and control functions legally conferred upon the Argentine Nuclear Regulatory Authority concerning radiological risks, as well as a critical analysis of the radiological risk acceptance criteria contained in the Argentine regulatory system. A summary of the application of regulatory standards AR 3.1.3. - 'Radiological criteria related to accidents in nuclear power reactors' and AR 4.1.3. - 'Radiological criteria related to accidents in research reactors' to concrete cases is made, while the favourable and unfavourable aspects of the risk acceptance criteria are discussed. The conclusion is that the Argentine regulatory system contains adequate radiological risk acceptance criteria, that the latter are consistent with the radiological protection principles applicable to man and that, for the moment, there is no need to perform any modifications that would broaden the conceptual framework on which such criteria are based.

    The Argentine National State, will establish the nuclear policy and perform the functions of research, development, regulation and supervision through two organisations, the National Atomic Energy Commission (CNEA) and the Nuclear Regulatory Authority (ARN). The National Atomic Energy Commission will continue to function as an autonomous entity, depending from the Ministry of Culture and Education of the Nation. Among the activities under its responsibility it will have to advise the National Executive Power on nuclear policy issues, promote the training of highly-specialised human resources, scientific and technological developments, execute development programs, promote programs for technological innovation, perform the responsibility for radiation waste management, etc. The Nuclear Regulatory Authority will act as an aunotomous entity in the jurisdiction of the Presidency of the Nation and will be responsible for the functions of regulation and control of the nuclear activity in everything which is related to radiological and nuclear safety, physical protection and control of the use of nuclear materials, nuclear facilities, licensing and international safeguards and give advise to the National Executive Power. Both institutions will depend from a Board of Directors composed by six members, one of which will be the Chairman and they will be responsible for the actions to comply with the objectives and functions mentioned above. In its last chapter, the law declares as subject to the privatisation the activities of nuclear energy generation presently developed by Nucleoelectrica Argentina Sociedad Anonima (NASA), as well as the Nuyclear Fuel Cycle used for the nuclear energy generation for industry or research and the Production of Radioisotopes developed by CNEA. This law revokes the articles numbers 2, 5, 9, 11, 16 and 17 of the Decree-Law N' 22.498/56 (B.O. 28-Dec-1956)

    The present study compared Argentine (N = 39) and U.S. (N = 43) children and their mothers on exploratory, symbolic, and social play and interaction when children were 20 months of age. Patterns of cultural similarity and difference emerged. In both cultures, boys engaged in more exploratory play than girls, and girls engaged in more symbolic play than boys; mothers of boys engaged in more exploratory play than mothers of girls, and mothers of girls engaged in more symbolic play than mothers of boys. Moreover, in both cultures, individual variation in children's exploratory and symbolic play was specifically associated with individual variation in mothers' exploratory and symbolic play, respectively. Between cultures, U.S. children and their mothers engaged in more exploratory play, whereas Argentine children and their mothers engaged in more symbolic play. Moreover, Argentine mothers exceeded U.S. mothers in social play and verbal praise of their children. During an early period of mental and social growth, general developmental processes in play may be pervasive, but dyadic and cultural structures are apparently specific. Overall, Argentine and U.S. dyads utilized different modes of exploration, representation, and interaction--emphasizing "other-directed" acts of pretense versus "functional" and "combinatorial" exploration, for example--and these individual and dyadic allocentric versus idiocentric stresses accord with larger cultural concerns of collectivism versus individualism in the two societies.

  13. Criminal offences considered in the Convention on the Physical Protection of Nuclear Material

    The Convention on the Physical Protection of Nuclear Material was signed in Vienna, on April 3, 1980, approved by Law 23.620 on September 28, 1998, and published in the Official Bulletin of the Argentine Republic on November 2, 1988. This Convention considers some aspects of Criminal Law and Criminal Procedural Law and integrates the normative hierarchical structure of the article 31 of the National Constitution. The adequacy of this Convention to the Argentine law is considered through two aspects: The first one examines figures existing in the Argentine Legislation about larceny and robbery of nuclear materials, misappropriation of nuclear materials, obtainment and fraud of nuclear materials, exaction through threat or intimidation, etc., which are considered in different articles of the Argentine Criminal Law. The second one analyses behaviours not foreseen in the Criminal Law and which are not qualified by the current Argentina's Criminal Code, such as exaction of nuclear material through the use of violence, the international perpetration of an act consisting to receive, possess, use, vacate, scatter nuclear material without legal authorization, or in the case that the act causes death, serious injuries to persons and others. The purpose of the future enactment of a new Nuclear Law is to put in order and fill-in gaps referred to different aspects such as civil liability in nuclear damages, characteristics of the nuclear damages, etc [es

Thoseconceptions are analyzed specially with respect to the way the subjects refer to what politicalcommitment and political identities were like in the past, concluding there is a doublephenomenon. On one hand, there is an adaptation, in their own and every-day political activitiesand practices, to an environment defined by uncertainty and volatility. On the other hand, theyexpress nostalgic definitions and references to a past in which political identities were allegedlystable, and parties (or their own party, at least had an intense organic life and a permanent bondwith voters.

    When faced with a threat to gender identity, people may try to restore their gender status by acting in a more gender-typical manner. The present research investigated effects of gender identity threat on self-presentations of agentic and communal traits in a Swedish and an Argentine sample (N = 242). Under threat (vs. affirmation), Swedish women deemphasized agentic traits (d [95% CI] = -0.41 [-0.93, 0.11]), Argentine women increased their emphasis on communal traits (d = 0.44 [-0.08, 0.97]), and Argentine men increased their emphasis on agentic traits (d = 0.49 [-0.03, 1.01]). However, Swedish men did not appear to be affected by the threat regarding agentic (d = 0.04 [-0.47, 0.55]) or communal traits (d = 0.23 [-0.29, 0.74]). The findings are to be considered tentative. Implications for identity threat research are discussed. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available The objective of this work is to study if children’s perception of parental relationship and parental empathy can predict prosocial behaviour during childhood. The sample was composed of 934 Argentine children, aged 9 to 12, of middle socio-economical level. The participants completed Argentine Scale of Children Perception of Parental Relationship (Richaud de Minzi, 2007, an Argentine adaptation of Scale of Prosocial Behaviour (Caprara and Pastorelli, 1993 and a questionnaire to measure children’s perception of parental empathy (Richaud de Minzi, 2006. Structural equations modeling (SEM analyses were conducted to explore our hypotheses. Six theoretical models fit the data very well. The results showed that parental styles of acceptance and pathological control impact on children prosocial behavior. Children’s perception of parental empathy was positively associated with children prosocial behavior. Finally, parental acceptance and pathological control were associated with children’s perception of parental empathy, but negligent parental behaviour did not.

    Full Text Available The study of didactic devices with the characteristics of RSC in the teachers' mathematics formation at an Argentine university has led to the future teachers elaboration of their own ideas about of the management of the mentioned device at the Argentine high school. In this paper, results of a semi-structured interview to future teachers are shown. The teachers were attending the last year of the teaching training college at an Argentine university. Our intention was to know the receipt that the future teachers have in the management of an education under the characteristics of RSC to manage the above device in their educational practices. One of the difficulties that the future teachers signal is to select the problematic question that allows to stimulate and to provoke the whole process of study. The choice of the mentioned question is assigned to the same teachers. This constitutes a limitation as for the comprehension and later management of an education for RSC.

    2014-06-01

    Full Text Available Oscar Bony was a key figure in the generation of avant-garde artists who famously broke with the Instituto Torcuato Di Tella in the wake of censorship at Experiencias ’68. He was also the official photographer for RCA’s affiliate record label in Argentina between 1967 and 1973, producing publicity for a new wave of rock n’ roll bands and solo popular music acts including Los Gatos and Arco Iris. Attending to key phases in his artistic oeuvre as well as close readings of his expertly crafted popular images, this article attempts to bridge these seemingly irreconcilable aspects of Bony’s practice. At first glance, his rock photography, known as el estilo Bony, has little relation to his art, and is perhaps even its political antithesis: “creative” work in the service of a top-down business model. Yet a closer look at both endeavors yields a lasting interplay between flesh and concept—at the grain of the work, a dialectic between incontrovertible index and crafted, calculated image—that was the artist’s central preoccupation in the fraught decade between the military coups. As such, Bony provides an opportunity to recover a category often absent from the Argentine art of this moment: the body, factual and libidinal.

  1. Polyacrylamide hydrogels: an effective tool for delivering liquid baits to pest ants (Hymenoptera: Formicidae).

    Buczkowski, Grzegorz; Roper, Elray; Chin, Darren

    2014-04-01

    Ant management in urban and natural areas often relies on toxic baits. Liquid baits are highly attractive to pest ants because they mimic natural food sources such as honeydew and nectar, the principal dietary components of many ants. However, liquid bait use has been limited owing to the lack of bait dispensers that are effective, inexpensive, and easy to service. The current study evaluated the potential of water-storing crystals (polyacrylamide spheres) to effectively deliver liquid thiamethoxam baits to laboratory colonies of Argentine ants, Linepithema humile Mayr. Results of laboratory trials show that bait crystals saturated in 25% sucrose solution containing 0.007% thiamethoxam are highly attractive to Argentine ants and highly effective against all castes and life stages, including workers, queens, and brood. Fresh bait crystals were highly effective and required approximately 2 d to kill all workers and approximately 6 d to achieve complete mortality in queens and brood. Results of bait aging tests show that the crystals lose approximately 70% of moisture in 8 h and the duration of outdoor exposure has a significant effect on moisture loss and subsequently bait acceptance and bait efficacy. A gradual decrease in mortality was observed for all castes and life stages as bait age increased. In general, fresh baits and those aged for ants that obtain thiamethoxam by feeding on bait crystals effectively transfer it to untreated recipient ants. The level of secondary mortality depended on the donor:recipient ratio, with approximately 40% recipient worker mortality with the 1:5 ratio and 15% recipient worker mortality with 1:10 or 1:20 ratios. However, no queens died in any transfer tests, suggesting that multiple feedings from multiple donors may be necessary to produce queen mortality. The results of the transfer tests demonstrate the role of trophallaxis in the distribution of thiamethoxam and confirm that thiamethoxam is effectively transferred in Argentine

    The red alga Polysiphonia morrowii, native to the North Pacific (Northeast Asia), has recently been reported worldwide. To determine the origin of the French and Argentine populations of this introduced species, we compared samples from these two areas with samples collected in Korea and at Hakodate, Japan, the type locality of the species. Combined analyses of chloroplastic (rbcL) and mitochondrial (cox1) DNA revealed that the French and Argentine populations are closely related and differ substantially from the Korean and Japanese populations. The genetic structure of P. morrowii populations from South Atlantic and North Atlantic, which showed high haplotype diversity compared with populations from the North Pacific, suggested the occurrence of multiple introduction events from areas outside of the so-called native regions. Although similar, the French and Argentine populations are not genetically identical. Thus, the genetic structure of these two introduced areas may have been modified by cryptic and recurrent introduction events directly from Asia or from other introduced areas that act as introduction relays. In addition, the large number of private cytoplasmic types identified in the two introduced regions strongly suggests that local populations of P. morrowii existed before the recent detection of these invasions. Our results suggest that the most likely scenario is that the source population(s) of the French and Argentine populations was not located only in the North Pacific and/or that P. morrowii is a cryptogenic species.

  3. The Need to Increase Regulatory Controls on Imports and Exports came from the Detection of an Argentine Import Containing Exceeding Pellets of Ir-192

    In Argentina, radioactive sources for application in Industrial Gamma radiography are manufactured using small metallic discs called pellets of radioactive isotope Ir-192, that are imported. They have to be shipped in specially sealed recipients according to their high radioactive levels. These recipients are large enough to contain activities as high as 296 TBq and are therefore approved as Type B(U) packages. This paper thoroughly describes a particular import of this material in which an exceeding 220 ± 2 Pellets (75,62 TBq) was found. The total amount of activity had not been declared adequately by the consignor. The corresponding notification to the Argentine Nuclear Regulatory Authority (NRA) was made by the importer and national manufacturer at the moment these particular Pellets were to be used for source production. The exceeding material doubled that which had been authorized to be imported. After the notification and since the material had entered to the country illicitly, customs legislations were applied in a legal process in which the Nuclear Regulatory Authority participated as well. The decision of the judge was to ship the exceeding cargo again to its proceeding country. However, a significant time had passed since the cargo arrived and the pellets had stuck to each other due to high temperature. This made them impossible to handle in order to encapsulate them as special form radioactive material again for their shipment in the available Type B(U) package. In the outcome, the material was retained at the manufacturer facilities, in its original packaging, with suitable radiological and physical conditions to guarantee safety and security, waiting until its activity had decayed to acceptable levels for its shipment as Type A package. As a result, a need to require further technical specifications from the vendor was detected. These specifications should warn about the period in which these Pellets may be utilized for source production before

Specifically, it shows how the signification of democracy was configured in the Regional Participatory Forums of Public Consultation (FPCP organized by the Federal Broadcasting Committee (COMFER which were held during 2009 as a previous stage to the presentation of the Audiovisual Communication Services Bill. Thus, from the analysis of the interventions in the FPCP, the paper presents the emergence of democracy as democratic gradualness configured in three analytical dimensions: what democracy is not, democracy as plurality, and democracy as participation.

  8. Participation of women in neurochemistry societies.

    2002-11-01

    Women have made important scientific contributions to the field of neurochemistry, and they have also been leaders in neurochemical societies throughout the world. Here I discuss women's involvement and leadership in six neurochemistry societies: American Society for Neurochemistry, Argentine Society for Neurochemistry, International Society for Neurochemistry, European Society for Neurochemistry, Japanese Society for Neurochemistry, and Asian-Pacific Society for Neurochemistry. The number of women who have been active in these societies and the level of their activity vary considerably. Neurochemical societies in the Western hemisphere, i.e., the American and the Argentine Society for Neurochemistry, have much greater numbers of women who have held office, been on council, or engaged in other leadership activities than in the rest of the world. The limited participation of women in the Japanese Neurochemistry Society relates to Japanese cultural views and was not unexpected. However, the relatively few women leaders in the International Society for Neurochemistry was a surprise. The European Society had a somewhat better record of female participation than did the International Society. The reasons for these differences are partly cultural, but factors related to when each society was formed, how it is organized, and how elections are structured undoubtedly play a role. Further analysis of these observations would be of interest from a sociological and a women's studies point of view.

    This paper explores how prevalent contemporary problematizations of organizations coincide with a widespread assessment that Organization Studies (OS) has run out of steam. This impasse, the paper argues, is largely due to the emergence of an organization-phobia that has come to seize several...... strands of theorizing. By attending to the wide-ranging and far-reaching history of this organization-phobia, the paper argues that OS has become increasingly incapable of speaking about its core object. I show how organizations went from being conceptualized as entities of major importance to becoming...... credibility and legitimacy to begin with, the organization-phobia resulting from this history has been implicated in dismantling organizations, and in making OS progressively irrelevant to a wider public....

    Full Text Available L’étude anthropologique des pratiques alimentaires de migrants boliviens de retour ayant longuement séjourné en Argentine permet d’aborder la problématique de la migration et de l’identité : la construction sociale, réelle et imaginaire, de la migration ne passe-t-elle pas aussi par l’alimentation ? Ce que l’on mange ici et là-bas éclaire, en creux, le succès ou l’échec donné à la migration par les migrants et aide à comprendre plus finement les significations locales données à la pauvreté et à la richesse, au bien-être et au mal-être. L’observation et les « récits de vie alimentaires » menés dans une perspective intergénérationnelle – sur l’importance de la consommation attribuée au pain, à la viande et au soda– conduisent finalement à s’interroger sur la situation sociale et symbolique des migrants de retour dans leur société d’origine comme dans la société d’accueil. Au-delà, l’étude montre que les pratiques et les représentations alimentaires reflètent et structurent à la fois des relations sociales, des relations de sexe et des rapports au corps, et qu’elles permettent d’induire des processus de construction d’identités complexes.The anthropological study of Bolivian returnees’ food practices, who have spent a long time in Argentina, leads us to deal with the problematic of migration and identity: as a matter of fact, the social construction of migration, either real or imaginary, is also based on alimentation. What is eaten here and there enlightens, in a way, the success or failure of their migration, as perceived from the migrants’ point of view; it helps to deeply understand the local significations given to poverty and wealth, to well-being and discontent. Observation and « intergenerational food life stories », conducted on the importance of consumption of bread, meat and sodas, finally lead to question the social and symbolic situation of returnees

    Full Text Available This article aims at analyzing the role of the ILO from the last dictatorship (1976-1983 to the initial years of the ensuing democratic government (1983-1985, as a step towards further and deeper research on the role of international labor organizations in the reconfiguration of labor relations in the 1980s. First, it focuses on particularly relevant dimensions of the ILO action during the dictatorship, paying special attention to the case 842 of the Committee of Freedom of Association concerning the violation of labor rights in Argentina, and the yearly conferences in Geneva as well as other relevant forms of interaction. Second, the paper analyzes the role of this organization during the first two years of the democratic government (1983-1985, based on newly available archival sources as well as coverage by the national press. Even though there are valuable contributions about the topic, few of them focus specifically on the role of international labor organizations and the influence on the definition of State policies towards the trade-union movement and the working class. This section analyzes some of the main governmental projects for the labor movement, particularly the so-called Mucci Law, a project of trade-union reorganization, some of the ways in which the international labor organizations participated in the public debate and discussions about it, the impact of the defeat of this governmental project in Congress and the ways in which connections and contacts with the ILO continued ahead. In terms of the conclusions of this paper, it is significant to notice that although there had been during 1976-1983 an accumulation of evidence and analysis about the evolution of the labor movement and labor conditions in Argentina at different ILO offices, the ILO officials do not seem to have taken advantage of these valuable resources from 1983 to 1985 to face the challenges and puzzles in the initial times of the new democratic government.

    Full Text Available We assessed the in vitro activity of selected antimicrobial agents against 95 Staphylococcus aureus strains causing both clinical and subclinical bovine mastitis belonging to 61 dairy farms from the Central dairy area of Argentina. Minimal inhibitory concentrations (MICs of penicillin, oxacillin, gentamicin, erythromycin, enrofloxacin and florfenicol were estimated. In addition, the agar diffusion test was performed. MIC50 and MIC90 were as follows: penicillin, 0.05 and 4 µg/ml; oxacillin, 0.25 and 0.25 µg/ml; gentamicin, 0.25 and 0.5 µg/ml; erythromycin 0.125 and 0.25 µg/ml; enrofloxacin 0.25 and 0.5 µg/ml, and florfenicol 4 and 8 µg/ml. b-lactamase activity was detected in 89% of 46 penicillin- resistant strains. Apart from penicillin, antimicrobial resistance in S. aureus causing bovine mastitis remains rare in Argentine dairy farms.Se evaluó la actividad in vitro de un grupo seleccionado de antimicrobianos contra 95 aislamientos de Staphylococcus aureus obtenidos de casos de mastitis bovina clínica y subclínica, en 61 rodeos lecheros de la cuenca central de Argentina. Fueron estimadas las concentraciones inhibitorias mínimas (CIM de penicilina, oxacilina, gentamicina, eritromicina, enrofloxacina y florfenicol. Además se realizó la prueba de difusión en agar. Las CIM50 y CIM90 obtenidas fueron: penicilina 0,05 y 4 µg/ml; oxacilina 0,25 y 0,25 µg/ml; gentamicina 0,25 y 0,5 µg/ml; eritromicina 0,125 y 0,25 µg/ml; enrofloxacina 0,25 y 0,5 µg/ml y florfenicol 4 y 8 µg/ml. Se detectó actividad de b-lactamasa en el 89% de las cepas resistentes a la penicilina. A excepción de lo observado para penicilina, la resistencia a los antimicrobianos en S. aureus causantes de mastitis bovina en Argentina parece ser un fenómeno poco frecuente.

    Full Text Available This paper researches the impact of the Argentine cooperative entities representing the contemporary public policy. We present a case study of the two largest third-degree cooperatives in the country, discuss the goals and strategies in interactions with State agencies. The results of the actions of actors define goals and strategies that can be convergent and / or divergent. We conclude that the links have been built with the State federations selected characteristics of complementarily and cooperation in general. Also, the power to influence the organizations surveyed in the definition of public policies is not only equity, but mainly the political opportunities and the ability to inter-stakeholder alliances through collective strategies.

    Competitive ability and numerical dominance are important factors contributing to the ability of invasive ant species to establish and expand their ranges in new habitats. However, few studies have investigated the impact of environmental contamination on competitive behavior in ants as a potential factor influencing dynamics between invasive and native ant species. Here we investigated the widespread contaminant selenium to investigate its potential influence on invasion by the exotic Argentine ant, Linepithema humile, through effects on reproduction and competitive behavior. For the fecundity experiment, treatments were provided to Argentine ant colonies via to sugar water solutions containing one of three concentrations of selenium (0, 5 and 10 μg Se mL −1 ) that fall within the range found in soil and plants growing in contaminated areas. Competition experiments included both the Argentine ant and the native Dorymyrmex bicolor to determine the impact of selenium exposure (0 or 15 μg Se mL −1 ) on exploitation- and interference-competition between ant species. The results of the fecundity experiment revealed that selenium negatively impacted queen survival and brood production of Argentine ants. Viability of the developing brood was also affected in that offspring reached adulthood only in colonies that were not given selenium, whereas those in treated colonies died in their larval stages. Selenium exposure did not alter direct competitive behaviors for either species, but selenium exposure contributed to an increased bait discovery time for D. bicolor. Our results suggest that environmental toxins may not only pose problems for native ant species, but may also serve as a potential obstacle for establishment among exotic species. - Highlights: • Argentine ant colonies exposed to selenium had reduced fecundity compared to unexposed colonies. • Viability of offspring was negatively impacted by selenium. • Queen survival was reduced in colonies

    Full Text Available Background. The morning home blood pressure (BP rise is a significant asymptomatic target organ damage predictor in hypertensives. Our aim was to evaluate determinants of home-based morning-evening difference (MEdiff in Argentine patients. Methods. Treated hypertensive patients aged ≥18 years participated in a cross-sectional study, after performing home morning and evening BP measurement. MEdiff was morning minus evening home average results. Variables identified as relevant predictors were entered into a multivariable linear regression analysis model. Results. Three hundred sixty-seven medicated hypertensives were included. Mean age was 66.2 (14.5, BMI 28.1 (4.5, total cholesterol 4.89 (1.0 mmol/L, 65.9% women, 11.7% smokers, and 10.6% diabetics. Mean MEdiff was 1.1 (12.5 mmHg systolic and 2.3 (6.1 mmHg diastolic, respectively. Mean self-recorded BP was 131.5 (14.1 mmHg systolic and 73.8 (7.6 mmHg diastolic, respectively. Mean morning and evening home BPs were 133.1 (16.5 versus 132 (15.7 systolic and 75.8 (8.4 versus 73.5 (8.2 diastolic, respectively. Significant beta-coefficient values were found in systolic MEdiff for age and smoking and in diastolic MEdiff for age, smoking, total cholesterol, and calcium-channel blockers. Conclusions. In a cohort of Argentine medicated patients, older age, smoking, total cholesterol, and use of calcium channel blockers were independent determinants of home-based MEdiff.

    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.

Así se dio inicio a la profesionalización de la transmisión y difusión de las danzas folklóricas en su carácter de danzas nacionales, tarea que quedaría concretada con la formación de un cuerpo de profesores nacionales de danza. Este proceso suponía el establecimiento de criterios de selección y transformación de aquellas danzas que se consideraran adecuadas para dar materialidad, mediante coreografías, música, vestimenta y eventos, al sentimiento de la nacionalidad. El folklore académico, en pleno proceso de consolidación como disciplina científica, fue también funcional al proyecto nacional, proveyendo los criterios para la creación del repertorio de danzas que sería enseñado en Buenos Aires y transportado luego a las provincias.En este artículo nos proponemos describir el desarrollo histórico que posibilitó la institucionalización de la enseñanza de las danzas folklóricas en la Argentina, y los efectos de dicha institucionalización.

    Reports of actual pediatric organ donor management practice among US organ procurement organizations are sparse, and the use of standardized management guidelines is unknown. A recent consensus statement from the Society of Critical Care Medicine, the American College of Chest Physicians, and the Association of Organ Procurement Organizations offers guidelines for the management of the pediatric organ donor. To describe the use of guidelines and routine practices in the management of the pediatric organ donor with respect to hemodynamics, lung and ventilator management, fluid and electrolytes, hormonal replacement therapy, the use of blood products, thermoregulation, and prophylactic antibiotics. Cross-sectional observational study using a survey and follow-up telephone interview with respondents from all 58 US organ procurement organizations. All 58 US Organ Procurement Organizations participated. A majority employed written guidelines for the management of pediatric donor hemodynamics, thermoregulation, fluids, and electrolytes. Management of blood products, the lung, and mechanical ventilation were less commonly committed to written guidelines, but common practices were described. All used various forms of hormonal replacement therapy and the majority administered empiric antibiotic therapy. Wide variation was observed in the management of the lung, mechanical ventilation, and glycemic control. Most OPOs used forms of standardized donor management for the pediatric organ donor although variation in the content of that management exists. Barriers to an evidence-based approach to the pediatric donor need to be determined and addressed.

  13. The organization of organ procurement.

    1989-01-01

    The American organ procurement system has improved and matured in the last five years. At the same time, the basic challenges facing it have remained substantially the same because the moral and legal framework of the system has not changed. Success at organ procurement continues to depend on the voluntary cooperation of medical professionals and the families of potential organ donors. The generosity of the American public is so great that the primary challenge facing organ procurement agencies is obtaining cooperation from hospitals and medical professionals. This calls for a "marketing" orientation aimed at those hospitals and professionals who are most likely to treat potential donors. The last five years have seen a more general acceptance of this appreciation of the central task of organ procurement. As a result, the overall effectiveness of the system has improved, as measured by the number of organs procured on a per capita basis and by the number of multiorgan donors obtained. Much of this improvement can be attributed to the diffusion of organizational techniques and approaches, and this diffusion has been encouraged by the involvement of national organizations and public bodies in the organ procurement community. The system remains uneven in its effectiveness and further improvement is possible. It is also possible that the next general round of improvement will result from the application of businesslike information management and marketing techniques.

Se reconstruye cómo el uso del discurso "antitotalitario" permitió a la dirigencia del partido no sólo condenar, por su asociación con las experiencias europeas, al régimen nacido de la revolución del '43 y al gobierno peronista, sino también cuestionar, por su cercanía con el peronismo, a los comunistas y a los miembros del ala izquierda del mismo Partido Socialista. El recorrido se cierra hacia comienzos de los años cincuenta, momento en que los intelectuales socialistas producen las más densas caracterizaciones del peronismo como fenómeno "totalitario", y justo antes de que la clave "anti-totalitaria" comience a ser cuestionada por la militancia socialista, en particular la juvenil.This article explores the press and the publications of the leaders of the argentine Socialist Party in an effort to account for one of the principal lines of its ideological message: the one represented by the different uses of the term "totalitarianism". It reconstructs the way in which the "anti-totalitarian" discourse allowed the party leadership not only to condemn the regime originated in the revolution which took place in 1943 and the Peronist government which emerged from it by associating both directly with contemporary European experiences, but also to challenge the Communists and left-wing members of the Socialist Party, because of their proximity to Peronism. This ideological itinerary was all but exhausted by the beginning of the '50s, when socialist intellectuals produced their densest characterizations of Peronism as a "totalitarian" phenomenon and just before the"anti-totalitarian" agenda began to be challenged, by grass-roots socialist militants, and particularly by the youth sector of the

    Full Text Available Abstract Background Requirements for organ donation after cardiac or imminent death have been introduced to address the transplantable organs shortage in the United States. Organ procurement organizations (OPOs increasingly use the Internet for organ donation consent. Methods An analysis of OPO Web sites available to the public for enrollment and consent for organ donation. The Web sites and consent forms were examined for the minimal information recommended by the United States Department of Health and Human Services for informed consent. Content scores were calculated as percentages of data elements in four information categories: donor knowledge, donor consent reinforcement, donation promotion, and informed consent. Results There were 60 Web sites for organ donation enrollment serving the 52 states. The median percent (10 percentile-90 percentile content scores of the Web sites for donor knowledge, donor consent reinforcement, and donation promotion were 33% (20–47, 79% (57–86, and 75% (50–100, respectively. The informed consent score was 0% (0–33. The content scores for donor knowledge and informed consent were significantly lower than donor consent reinforcement and donation promotion for all Web sites (P Conclusion The Web sites and consent forms for public enrollment in organ donation do not fulfill the necessary requirements for informed consent. The Web sites predominantly provide positive reinforcement and promotional information rather than the transparent disclosure of organ donation process. Independent regulatory oversight is essential to ensure that Internet enrollment for organ donation complies with legal and ethical standards for informed consent.

    2008-01-01

    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

    2009-01-01

    This paper explores the economic, social and environmental context, drivers and impacts of increased demand for Argentine soy-based biodiesel. It is based on extensive stakeholder interviews in Argentina, including those in government, academia and the third sector; as well as participant observation with communities in soy cultivation areas; and review of relevant academic and grey literatures. Given Argentina's history of political instability and relatively weak levels of environmental protection, there is reason to be sceptical of the likely effectiveness of biofuel sustainability certification as applied to Argentine soy. Direct contracts between feedstock producers and biodiesel retailers may be a more reliable approach to minimise adverse environmental and social impacts than certification alone.

    Vitamins are vital for normal growth and survival of living organisms and they are distributed in feedstuffs in small quantities. This review is focused on the liposoluble vitamins (A, D, E and K) in the diets and metabolic responses of the Argentine penaeoid shrimps Pleoticus muelleri and Artemesia longinaris, distributed along the South American coast line. Growth, survival and histological analyses serve as indicators of the nutritional value derived from vitamin deficiency. Liposoluble vitamins are also related to stress, antioxidant defense and immune response of shrimps. Effective diet for shrimp culture that provide not only macronutrients including protein and lipid but also micronutrients such as vitamins for optimal growth is an ever improving subject. This review may help formulating suitable feeds for shrimps.

    The Human Organ Preservation Effort is a government organ procurement organization that pioneered the Deceased Organ Donation Program in the Philippines. Deceased organ donation comprises only 20% of kidney transplantation in the Philippines in the last 3 years. Various measures were implemented to improve deceased organ donor referrals and organ retrieval. To compare outcome of deceased organ donor referrals from 2002 to 2008 and 2009 to 2012 in the Philippines. This retrospective study reviewed the deceased organ donor referrals from 2002 to 2008 and 2009 to 2012. There were 437 referrals for potential deceased organ donors from 2009 to 2012, compared to 434 referrals from 2002 to 2008. Referrals were mainly trauma victims (76%) followed by those with cerebrovascular accidents (12%). In the recent cohort, 81% were approached and 60% consented for donation, but only 23% were retrieved and transplanted. Among those not retrieved, the majority (19%) were medically unsuitable and 6% retracted their consent. Although there was an increasing trend of organ donation referrals in the last 4 years, only 25% were procured. The reasons for nonprocurement should be addressed. Copyright © 2014 Elsevier Inc.

  3. The anxieties of globalization: antidepressant sales and economic crisis in Argentina.

    2004-04-01

    This paper describes the role of market research firms in shaping the actions of key players in the pharmaceutical arena. It focuses on strategies for marketing novel antidepressants (selective serotonin reuptake inhibitors, SSRIs) to doctors in Buenos Aires during the Argentine financial crisis of 2001, posing the question of whether increased antidepressant sales were due to the social situation or to promotional practices. This case demonstrates how 'pharmaceutical relations' - interactions between doctors and pharmaceutical companies - are structured by a gift economy whose effects are monitored through the sales numbers produced by database firms. It suggests that the use of these numbers takes on special importance given the distinctiveness of both the Argentine context and the antidepressant market. More generally, the case points to the interpretive flexibility of psychotropic medication. In the Argentine setting, doctors' prescription of SSRIs was dependent neither on a diagnosis of depression nor on a biological understanding of mental disorder. These drugs found a different means of entering the professionally mediated marketplace: doctors understood and used SSRIs as a treatment not for a lack of serotonin in the brain, but for the suffering caused by the social situation - the sense of insecurity and vulnerability that the economic and political crisis had wrought.

    Full Text Available The goal of this paper is to estimate the productive efficiency of Argentine banks. For this purpose, panel data of the universe of banks under the supervision of the Central Bank of the Republic of Argentina (BCRA has been collected. In order to build the bank´s indicators, we used a database of 66 institutions, with annual information for the period 2009-2013. The sources of information were both the BCRA´s web site (www.bcra.gov.ar, and the Buenos Aires Stock Exchange´s web site (www.bolsar.com. It has been selected an efficiency indicator ranging between 0 and 1, meaning the lowest and highest level of efficiency, respectively. The concept of efficiency used here is a relative one, because it considers a Bank´s performance in relation to the behavior of the best players in the industry, being the latter the base of the industry benchmark or frontier. The results show that the mean efficiency of Argentine banks is 0,8277 in the specific period under consideration.

    Full Text Available This article discusses the request for an advisory opinion originated in Case "Sancor c/ Dirección General de Aduanas". This case emerged from the resolution of the Argentine Ministry of Economy which set export duties of 5% to certain milk products, without discriminating the destination of them, i.e. including members and as well as non-members of the Southern Common Market (MERCOSUR. In this way, and after a long judicial process, in October 2009 Argentina’s Supreme Court of Justice (CSJN requested an advisory opinion to the Permanent Review Court of the MERCOSUR, asking the question "Does the Treaty of Asunción require Member States of MERCOSUR the obligation not to impose duties on exports of goods which are originated in one of them and which have another Member State as its final destination?" This article describes the historical circumstances surrounding the Argentine governmental measure, and then analyzes three specific issues related to the request of the advisory opinion by the Supreme Court: 1 the place of international law in the Argentine legal system, 2 the procedural legitimacy of the decision of the Court, and 3 some substantial topics involved in the requested advisory opinion.

  6. Evaluation of the international limitations and conditions of the Argentinian nuclear politics

    It is a broadly accepted fact that the Argentine Republic is one of the few development countries that has reached an advance status in the world in pacific applications of nuclear science and technology. A retrospective vision of the main technical and political aspects that characterized the process to global scale allows to confirm, starting from the theory of the International Relations, that the position reached by the country was the consequence of a coherent effort sustained under the almost exclusive conduction of the National Atomic Energy Commission (CNEA). The Nuclear politics of Argentine in the international concert during the last fifty years, sample a behavior of non adhesion to the juridical treaties commitments that were considered limitative for the initial objectives proposed when President General J. D. Peron created the CNEA in 1950: self-sufficiency and national autonomy. This continuity shows an unusual coherence in the foreign policy of the country maintained by all the governments that exercised the power during five decades. The result of this investigation task has allowed to elaborate a complex, reasonably coherent vision of the consequences that the limitations and conditions on the Argentine nuclear politics had in the three temporary dimensions and in different levels. From the theoretical point of view, the scenario starts from the crisis of the Utopism that revaluate the Classic Realism (H. Morgenthau) after the Second World War. In the next stage K. Waltz's Structural Realism starts when the internationalization process of the nuclear technology begins in the 50. Other theoretical models: Complex Interdependence (R. Keohane and J. Nye) and Peripheric Realism (C. Escude) at local level seem to be the representative models to describe the Argentine political behavior in the nuclear politic and to prove that the main variable in this field was the genuine domain of the scientific and technological knowledge developed in the national

    In this work one simulates, using the program MESSAGE, the generation park electric of the Argentine Republic and their possible expansion, with restrictions in the readiness of fossil fuels. This, as other models of planning energetics promoted by IAEA, optimizes the expansion of the net having as function objective the smallest cost in the system. 25 years they were simulated, adopting like base the anus 2000 and considering different scenarios of internal and external demands. It was analysed the increase of the demand with restrictions in the readiness of the natural gas in the winter periods, since the Argentinean electric system has a great dependence of this fuel. To cover the increase of the electric demand, were selected the machines and fuels, at the moment available, with more technical and economic possibilities. In the scenarios without restrictions to the use of natural gas the program selects to the nuclear power station of Atucha II, to the increase of bench mark of the hydraulic power station of Yacireta and combined cycles that burn natural gas. In those in that the supply of natural gas is limited, it selects previously besides the signal ones, other nuclear power stations, other hydroelectric projects and turbines of gas operating with gas oil to cover the top requirements.

    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)

  2. Managing mechanistic and organic structure in health care organizations.

    Science.gov (United States)

    Olden, Peter C

    2012-01-01

    Managers at all levels in a health care organization must organize work to achieve the organization's mission and goals. This requires managers to decide the organization structure, which involves dividing the work among jobs and departments and then coordinating them all toward the common purpose. Organization structure, which is reflected in an organization chart, may range on a continuum from very mechanistic to very organic. Managers must decide how mechanistic versus how organic to make the entire organization and each of its departments. To do this, managers should carefully consider 5 factors for the organization and for each individual department: external environment, goals, work production, size, and culture. Some factors may push toward more mechanistic structure, whereas others may push in the opposite direction toward more organic structure. Practical advice can help managers at all levels design appropriate structure for their departments and organization.

    Organic-organic heteroepitaxy can represent the winning technique for growing crystalline and oriented heterostructures of organic semiconductors. However, a sound physical interpretation of mechanisms that control epitaxy is still missing for these low symmetry molecular systems, generally not obeying the usual lattice matching rules for inorganic systems. We discuss here a couple of paradigmatic examples of organic-organic heteroepitaxy suggesting a possible physical rationale for the formation of the heterostructure interfaces as it arises from experimental characterization and computer modeling with atom-atom potential simulations.

Repression, based on state terror, was territorially organized by the Argentine Army, which was responsible for a national operational coordination and the construction of a tripartite scheme of power. This article explores Argentina Navy’s action and the configuration actions and repressive practices from a case of regional perspective. Our interest is to discuss those processes in place long-term repression of the Navy in bounded contexts, the towns of Bahía Blanca and Ensenada, and its projections in the democratic era. We are interested in solving, in which ways the Argentina Navy exerted its repressive action on a particular civil sector were what as was the workers?

    Full Text Available The article analyses a group of unregistered novels in Argentine literature histories from the 19th century, which dealt with crime issues. A critical reading about these histories will try to delineate through the traits on which criminals are outlined, a specific moment in the cultural discourse: that from the so-called National Organization Process. This process is defined by historiography as a phase in which Argentina experiences a transformation process that implies the evolution from a traditional to a modern society, due to the politics implemented by the National State. This synchronic perspective is complemented with the purpose of contributing to the trace of the changes over time, recovering to a characterization of criminals previous to landmarks such as the magazine Revista Criminal (1873, or the implementation of the sensational press.

    2006-11-01

    Full Text Available Framed in Communitarian Social Psychology, this study examines the Argentine experience of worker takeovers. Such takeovers had their origin in the crisis that the country faced in the late 90s. We analyze what the takeover meant to the workers in terms of their subjective identity. Their collective action presents an alternative to the usual triad of rights: to exist, to work, and to receive support. It displays new forms of agency and resistance to unemployment and its negative social labelling. Focussing on two workers' cooperatives, we examine the main changes in individuals' identity, in their organization among themselves, as they try to survive in the market. Finally, we examine points of contact and difference between these workers' struggles and new social movements in their relation to community and State.

    Full Text Available The colonial ascidian Synoicum molle (Herdman, 1886 was recorded for the first time after its original description. The slope area where S. molle was discovered during the Challenger Expedition (1872-1876, located at the mouth off Río de La Plata (Argentine Sea, still remains highly underexplored. During a series of deep-sea prospections along the SW Atlantic (A.R.A. Puerto Deseado, August 2012, 7 colonies of S. molle were collected few km from the type locality. The finding permitted to perform, for the first time, a complete morphological description of this species. The proper identification of marine species, especially deep-sea organisms, has implications for the general knowledge of biodiversity, a necessary tool for the conservation and study of ecosystem benefits that marine environments provide.

    2015-01-01

    Full Text Available This paper analyzes the way in which migration policies impact in the trajectories of Bolivian women who live and work in the outskirts of the main cities of Argentina. It focuses on three cases representative of the experiences of women laborers who, coming from the poorest rural areas of Bolivia, crossed the international border when Argentine migration policy was very restrictive. It shows that symbolic and socio-economic borders keep on excluding them, as well as other labor migrants, within the Argentine territory even when the current Migration Law enacted in 2004 is more inclusive, since it grants human and social rights to the migrants. It highlights the way in which particular state control mechanisms operate nowadays both at the international border and within the Argentine territory, and analyses the difficulties that these women experience due to their positions of class, ethnic, gender, nationality and migratory status. It remarks that despite the changes in the immigration policy of Argentina, state policies keep on controlling labor migrations in accordance with the paradigm of the governance of migration. It also analyses the strategies that these women develop in order to sort out state control policies. Therefore, it considers that they are active agents even though they still have feelings of fear and trauma associated with the crossing of borders.

    Highlights: • Fine scale distribution of two Argentine stocks constrains the Cd accumulation rates. • Cadmium levels and accumulation patterns were different between geographic groups. • Marine diet has a major influence than the impact degree of origin environment. • Engraulis anchoita is the main Cd vector species in Argentine shelf for Franciscana. • Information is valuable for the conservation of Franciscana, a vulnerable species. -- Abstract: Franciscana dolphin is an endemic cetacean in the southwestern Atlantic Ocean and is classified as Vulnerable A3d by the International Union for Conservation of Nature. Cadmium accumulation was assessed in two geographic groups from Argentina; one inhabits the La Plata River estuary, a high anthropogenic impacted environment, and the other is distributed in marine coastal, with negligible pollution. Despite the environment, marine dolphins showed an increase of renal Cd concentrations since trophic independence; while in estuarine dolphins was from 6 years. This is associated with dietary Argentine anchovy which was absent in the diet of estuarine dolphins, being a trophic vector of cadmium in shelf waters of Argentina. Cluster analysis also showed high levels of cd in association with the presence of anchovy in the stomach. The difference in the fine scale distribution of species influences dietary exposure to Cd and, along with other data, indicates two stocks in Argentina

    Outdoor residual sprays are among the most common methods for targeting pestiferous ants in urban pest management programs. If impervious surfaces such as concrete are treated with these insecticides, the active ingredients can be washed from the surface by rain or irrigation. As a result, residual sprays with fipronil and pyrethroids are found in urban waterways and aquatic sediments. Given the amount of insecticides applied to urban settings for ant control and their possible impact on urban waterways, the development of alternative strategies is critical to decrease the overall amounts of insecticides applied, while still achieving effective control of target ant species. Herein we report a "pheromone-assisted technique" as an economically viable approach to maximize the efficacy of conventional sprays targeting the Argentine ant. By applying insecticide sprays supplemented with an attractive pheromone compound, (Z)-9-hexadecenal, Argentine ants were diverted from nearby trails and nest entrances and subsequently exposed to insecticide residues. Laboratory experiments with fipronil and bifenthrin sprays indicated that the overall kill of the insecticides on Argentine ant colonies was significantly improved (57-142% increase) by incorporating (Z)-9-hexadecenal in the insecticide sprays. This technique, once it is successfully implemented in practical pest management programs, has the potential of providing maximum control efficacy with reduced amount of insecticides applied in the environment.

    Full Text Available La narrativa de Emile Zola, que ejerciera una influencia poderosa en toda Europa, originó también en Argentina una honda renovación novelística, que empieza en la década de los 80 del pasado siglo y se generaliza en la década siguiente. No obstante, la novela argentina de final de siglo se halla en la encrucijada de varias corrientes estéticas. Entre ellas, la fuerza cosmovisionaria y estilística del modernismo no encuentra resistencia. En este artículo se analizan los ideales y técnicas modernistas en tres novelas representativas del naturalismo argentino: Sin rumbo, de Eugenio Cambaceres; Horas de fiebre, de Segundo I. Villafane, y La Bolsa, de julián Martel. The narrative art of Zola which exerted such powerful influence all over Europe, also marked profound changes in Argentine fiction, beginning in the decade of the 1980's and becoming generalized in the ensuing period. The end-of-the-century Argentine novel, however found itself at the crossroads of several esthetic tendencies. Among the latter, the cosmovisionary and stylistic strength of modernism found no resistance. The present article analyses modernist techniques and ideals is three novels representative of Argentine naturalism, namely, Sin rumbo of E. Cambaceres; Horas de fiebre, of S.I. Villafane; and La Bolsa, of Julián Martel.

Inclusion criteria: children ≤ 2 years old with their first febrile UTI and normal ultrasound, voiding cystourethrography and dimercaptosuccinic acid scintigraphy, according to the algorithm established by the Argentine Society of Pediatrics in 2003, treated between 2003 and 2010. The comparisons between algorithms were carried out through retrospective simulation. Eighty (80) patients met the inclusion criteria; 51 (63%) had vesicoureteral reflux (VUR); 6% of the cases were severe. Renal scarring was observed in 6 patients (7.5%). Cost: ARS 404,000. Radiation: 160 millisieverts. With the Argentine Society of Pediatrics' algorithm developed in 2015, the diagnosis of 4 VURs and 2 cases of renal scarring would have been missed. The cost of this omission would have been ARS 301,800 and 124 millisieverts of radiation. British and American guidelines would have missed the diagnosis of all VURs and all cases of renal scarring, with a related cost of ARS 23,000 and ARS 40,000, respectively and 0 radiation. Intensive protocols are highly sensitive to VUR and renal scarring, but they imply high costs and doses of radiation, and result in questionable benefits. Sociedad Argentina de Pediatría

  14. Using matrix organization to manage health care delivery organizations.

    1990-01-01

    Matrix organization can provide health care organization managers enhanced information processing, faster response times, and more flexibility to cope with greater organization complexity and rapidly changing operating environments. A review of the literature informed by work experience reveals that the use of matrix organization creates hard-to-manage ambiguity and balances of power in addition to providing positive benefits for health care organization managers. Solutions to matrix operating problems generally rely on the use of superior information and decision support systems and extensive staff training to develop attitudes and behavior consistent with the more collegial matrix organization culture. Further improvement in understanding the suitability of matrix organization for managing health care delivery organizations will involve appreciating the impact of partial implementation of matrix organization, temporary versus permanent uses of matrix organization, and the impact of the ambiguity created by dual lines of authority upon the exercise of power and authority.

    2012-06-19

    Over the past two decades, organic semiconductors have been the subject of intensive academic and commercial interests. Thiazole is a common electron-accepting heterocycle due to electron-withdrawing nitrogen of imine (C=N), several moieties based on thiazole have been widely introduced into organic semiconductors, and yielded high performance in organic electronic devices. This article reviews recent developments in the area of thiazole-based organic semiconductors, particularly thiazole, bithiazole, thiazolothiazole and benzobisthiazole-based small molecules and polymers, for applications in organic field-effect transistors, solar cells and light-emitting diodes. The remaining problems and challenges, and the key research direction in near future are discussed. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2006-01-01

    Full Text Available One of the most used buzz-words in (e-business literature of the last decade is virtual organization. The term "virtual" can be identified in all sorts of combinations regarding the business world. From virtual products to virtual processes or virtual teams, everything that is “touched” by the computer’s processing power instantly becomes virtual. Moreover, most of the literature treats virtual and network organizations as being synonyms. This paper aims to draw a much more distinctive line between the two concepts. Providing a more coherent description of what virtual organization might be is also one of our intentions.

    2017-04-01

    Full Text Available We analyze the organic and non-organic production choices of two firms by considering customers’ trust in organic food products. In the context of customers’ possible willingness to pay a premium price and their mistrust in organic food products, two firms first make choices on offering organic and non-organic food products. If offering organic products, a firm can further invest in the credence system to increase customers’ trust in their organic products. At the final stage, two firms determine prices. We provide serval insights. First, we characterize the market conditions in which only one firm, both firms or neither firm will choose to offer organic food products. We find that the higher the production costs or credence investment costs for organic food products are, the more likely firms are to choose to produce non-organic food products. Second, if it is expensive enough to invest in organic credence, offering organic food products may still be uncompetitive, even if organic production cost appears to have no disadvantage compared to non-organic food products. Third, we highlight how the prices of organic food products in equilibrium are affected by market parameters. We show that when only one firm offers organic food products, this firm tends to offer a relatively low price if organic credence investment is expensive. Fourth, we highlight how one firm’s credence investment decision in equilibrium can be affected by the product type choice of the other firm. We find that the investment in organic credence is lower when both firms offer organic food products compared with the case when only one firm offers organic food products.

  1. Does organic crowding out influence organic food demand?

    DEFF Research Database (Denmark)

    Hansen, Lars Gårn; Andersen, Laura Mørch

    All Previous studies of organic food demand that investigating substitution focus on specific food submarkets and have to assume separability from other food consumption. However, consumers typically associate attributes such as e.g. healthiness and environment friendliness with organic variants...... of most types of food. If such general organic attributes are important for consumer behaviour then separability may not hold because the general attribute obtained from one type of organic food may be a close or even perfect substitute for the same attribute obtained from other types of organic food....... In this paper we utilize a unique Danish micro panel where all food demand is registered on a disaggregated level with an organic/nonorganic indicator to estimate a general food demand system with organic variants. We clearly reject the usual separability assumption and find that the behaviour of Danish...

    Full Text Available Research Question: The existence of organizations in competitive markets depends on their ability to stay competitive. Quality departments play a key role in organizing and ensuring quality. Purpose: The survey tries to determine the correlation between the existence of quality departments and organization of quality in organizations; our hypothesis is that the correlation is very strong. Method: A survey was performed in 484 large and medium-sized organizations in Slovenia to examine the situation in this area. Pearson's χ2-test was used for data processing and results presented in a contingency table. Results: Organizations with quality departments more frequently also have certificate ISO 9001 in comparison with organizations without quality departments. Also these organizations more frequently have supplier-relations teams, monitoring system of suppliers' progress and excellence centers. In short, the quality in these organizations is organized on a higher level than in organizations without quality departments. Organization: The role of quality department is important for organizations. The findings of the research are important for decision making in organizations. Society: Each organization contributes to efficiency and effectiveness of a nation. The organizational level of the nation can be measured by number of certificates per capita. Originality: The research is unique because of the research model and method applied. Limitations/Future Research: The research is limited to large and medium-sized organizations in Slovenia.

    Aquarius is a combination L-band radiometer and scatterometer designed to map the salinity field at the ocean surface from space. It will be flown on the Aquarius/SAC-D mission, a partnership between the USA space agency (NASA) and Argentine space agency (CONAE). The mission is composed of two parts: (a) The Aquarius instrument being developed as part of NASA.s Earth System Science Pathfinder (ESSP) program; and (b) SAC-D the fourth spacecraft service platform in the CONAE Satellite de Aplicaciones Cientificas (SAC) program. The primary focus of the mission is to monitor the seasonal and interannual variations of the salinity field in the open ocean. The mission also meets the needs of the Argentine space program for monitoring the environment and for hazard detection and includes several instruments related to these goals.

    Full Text Available In Argentina, innovations related to biotechnologies were rapidly adopted while initially there was an absence of a large social debate. To understand this absence, the institutional framework which legitimized technological innovations must be addressed. This framework was undoubtedly one of the conditions of success of the dissemination of the agribusiness model. It´s unfolding also evidences the restructuring of local rural dominant classes that led to the emergency of new social actors. These were the “innovators” gathered in the Argentine Association of No-Tilling Farmers (or AAPRESID.  Here, we analyze how innovations were introduced and legitimated in Argentina. In contrast to what AAPRESID has termed as a “paradigmatic revolution”, we will characterize the introduction of biotechnologies in Argentine agriculture as a “conservative revolution”.

    Full Text Available This paper explains why the Argentine and Chilean presidents believe important to face the political past of their countries; or in other words, why no president resists the temptation to interfere in the issue of public policies of the memory through different strategies with different political costs. In that sense, we try to explain what factors mainly affect the decision of the Argentine and Chilean presidents when they adopting public policies of memory. Following the analysis made by means of logistic regressions, it is estimated that the ideology of the leaders, affect on the repair policies. In justice policies, the analysis shows that these are particularly conducive in times of critical juncture. And in the symbolic policies, anniversaries are not so decisive as might be expected.

    Organ demand exceeds availability of transplantable organs. Organ procurement continues to suffer from failures to identify potential donors, inability to obtain consent for donation, as well as failures to retrieve certain organs as donor demographics change. The purpose of this article is to propose how sequentially introduced measures can increase organ donation rates as well as improve organ procurement. We analysed the effect of stepwise improvements in the organ procurement process patients in a university-based surgical intensive care unit over a 20-year period. We related newly introduced measures in the organ retrieval process with changes in donation rates. We specifically targeted these three main steps in the donation process: donor identification, conversion of potential donors to actual donors, and organ protection during the procurement process. Finally, we assessed the effect of the same measures on organ procurement after introduction in other hospitals of the same organ procurement region. Introduction of quality improvement steps increased all of the observed parameters. The number of organ donors was stabilised due to a better identification of potential donors, a major increase in conversion from potential to actual donors, and an increase in extended criteria donor. Improvements in organ protection led to higher rates of organs transplanted per donor and increased recovery of lungs and hearts despite increasing donor age. The same measures were introduced successfully in other hospitals in our organ procurement region. Sequential improvements in organ procurement can increase the yield of retrieved organs. The same measures can be applied to other hospitals and lead to comparable improvements in organ donation. Published by Elsevier Ltd.

    2011-10-01

    Organ printing, or the layer by layer additive robotic biofabrication of functional three-dimensional tissue and organ constructs using self-assembling tissue spheroid building blocks, is a rapidly emerging technology that promises to transform tissue engineering into a commercially successful biomedical industry. It is increasingly obvious that similar well-established industries implement automated robotic systems on the path to commercial translation and economic success. The use of robotic bioprinters alone however is not sufficient for the development of large industrial scale organ biofabrication. The design and development of a fully integrated organ biofabrication line is imperative for the commercial translation of organ printing technology. This paper presents recent progress and challenges in the development of the essential components of an organ biofabrication line. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Vetiver oil (Vetiveria zizanoides has been used as perfume materials, cosmetics, fragrance soaps, anti-inflammation, repellent, and insecticidal agents. Organic vetiver oil has higher economical value than non-organic vetiver oil and it has been regarded to be able to compete in the global market. Therefore, studies have been carried out using 1 hectare of land and the first generation of organic vetiver oil has produced 0.57% of yield, greater than non-organic (0.50%. The quality of organic and non-organic vetiver oil was analyzed by Indonesian Standard (SNI parameter, pesticide residue test, chemical composition by GC/MS, and the appearance of vetiver root. In general, the result of organic and non-organic vetiver oil has fulfilled the national standard; the quality of organic vetiver oil was better than non-organic one. Physically, the appearance of organic vetiver root was better than non-organic vetiver root; organic vetiver root was denser, more appealing, and did not have any black spots. The pesticide residue of organic vetiver oil was lower than non-organic vetiver oil. Based on SNI test, vetiverol (oxygen compounds in organic vetiver oil was higher than non-organic vetiver oil.

    Full Text Available This paper presents an expert-based operationalization strategy to measure the degree of democracy in the Argentine provinces. Starting with a mainstream and “thick” definition of regime type, I assess each of its aspects using a subjective or perception-based approach that taps the knowledge of experts on the politics of each province. I present and justify the methodological design of the resulting Survey of Experts on Provincial Politics (SEPP and conduct a preliminary analysis of its results. Some aspects of the provincial regimes appear to be clearly democratic, while others are mixed or even leaning towards authoritarianism. Moreover, some show little interprovincial variance, while others vary considerably from province to province. An analysis of the central tendency and dispersion of the survey items allows for a general description of the Argentine provincial regimes. Inclusion is the most democratic dimension, while the effectiveness of institutional constraints on the power of the Executive is the most deficient. Electoral contestation is generally free of traditional forms of fraud, but incumbents often command far more campaign resources and media attention than do their challengers. Physical repression is rare, but opponents in some provinces face subtler forms of punishment. While the survey does not uncover any clear cases of subnational authoritarianism, stricto sensu, provincial regimes do vary significantly from basically democratic to clearly hybrid. Este artículo presenta una estrategia de operacionalización basada en expertos para medir el grado de democracia en las provincias argentinas. Partiendo de una definición convencional y “densa” del tipo de régimen, se evalúan cada uno de sus aspectos usando un enfoque subjetivo o basado en percepciones, que explota el conocimiento de expertos en la política de cada provincia.

Workshops allow the women to become more active on their own behalf and contribute to the reorientation of health and social services to better meet their needs. Due to the stigma attached to AIDS in Argentina, ANW works to ensure the human rights of these women through participation in the Ministry of Interior Programme against Discrimination and in public events that inform the community about the concerns of HIV positive women with regard to discrimination. A bulletin provides scientific and medical information, news on activities, model advocacy and policy statements, and addresses of support agencies. Contributions are accepted from all HIV positive women. In order to reach isolated cases outside of the capital, links are maintained with other AIDS organizations in the nation.
