    Pleistocene and Holocene superficial deposits, which have been recognized in an area of 1500 km2 in the northeast flank of Sierras Australes, are characterized. In divide they are underlain by silts and siltstone which are called Sediments Pampeanas. There, a lower sequence, consisting mainly of aeolian sediments (loess) with scarce fluvial deposits and diamictons, was recognized. In some places an upper sequence that is product of aeolian and anthropogenic activity, was also recognized. In the valley sequences, the loess deposits can not only be underlain by fluvial sediments but can also overlain them. The more recent fluvial deposits which have eroded loess sequences are of the post conquest age [es

    Full Text Available Se presentan tres nuevos registros de especies de peces óseos cuya distribución corresponde a aguas tropicales, capturados por buques pesqueros en la costa de la Provincia de Buenos Aires, Argentina (CPBA, 36°-38°S. Los ejemplares corresponden a las especies: Rachycentrum canadum, Elops saurus y Caulolatilus chrysops. Estos registros amplían significativamente el límite austral de su distribución. La presencia ocasional de estas especies está asociada al transporte de agua subtropical cálida proveniente de la plataforma continental brasilera. Esta hipótesis es probada mediante el análisis de imágenes satelitales de temperatura superficial del mar.We document the southern records of three species of tropical bony fishes along the coast of Buenos Aires Province, Argentina (CBAP, 36-38°S. Rachycentrum canadum, Elops saurus and Caulolatilus chrysops were caught by bottom-trawl commercial vessels. Records presented here significantly extend southward their latitudinal distribution from those previously reported. Using sea surface temperature satellite images we show a southward warm circulation event from Brazil as a putative factor to explain the occurrence of these bony fishes in the CBAP.

    The School of Medicine of Austral University incorporated palliative care as an elective in undergraduate medicine curriculum during 2010. We analyzed the experience and results after 3 years of teaching palliative care. We compared students who chose palliative care as an elective subject (PC Group) with students who did not (Non-PC Group). We focused on the experience of contact with palliative care patients and self-perceived attitudes. Additionally, the impact produced by palliative care education in knowledge, self-perceived attitudes, and comfort was evaluated. All the students tested completed a questionnaire on their attitude when exposed to dying patients. Students in the PC Group completed an additional questionnaire to assess their level of knowledge and their self-perceived comfort when interacting with patients. We tested 146 students. All students in the PC Group and 95.2% in the Non-PC Group considered that specific death issues ought to be part of the curriculum. Some students indicated that they could be present in a mandatory course. Before taking their elective, students in the PC Group confirmed a lack of technical training to understand palliative care patients, as did those students in the Non-PC Group. After taking a palliative care elective students expressed an improvement in self-perceived attitudes toward suffering and there was a significant increase (ppalliative care education provides opportunities to improve attitudes not specific to this discipline: interprofessional collaboration, holistic care, patient-centered care, self-awareness, and humanism. We conclude that an exposure to palliative care improved student's perception about the complexities of dying patients and their care.

    Full Text Available In this paper, we present a description of some concrete processes that made up the transformations in the metropolitan configuration and functioning in Buenos Aires in the 1990s during the 20th Century. We are referring to components related to the impact of processes at the macro level (national and international pertaining to restructuring and globalisation. We aim to understand the “forces” that mediate between the global and the local arenas, identifying the actors and the relationships behind metropolitan changes as well as searching for the meaning that the city acquires and which is understood as “privatisation”. In the first section of the paper, this concept is made explicit.

    To celebrate the 60th anniversary of Medicina (Buenos Aires) an International Symposium was held at the National Academy of Medicine of Buenos Aires on the 6-7th of October 1999, under the title of Clinical investigation in the next millennium. This meeting was a success as evidenced by the 376 registered attendants. Sixty years of uninterrupted publication is an uncommon feat in our midst and this could be achieved on the basis of a number of factors which include, the initiative of those who founded the journal, the unfailing motivation and dedication of the Editorial Board and primarily the authors who have trusted us with their manuscripts. Of the many important papers published, we have selected a few which proved to be milestones in the development of Argentine biomedicine. It is to be hoped that the future will bring an increase in our impact index through more and even better papers eventually reflecting the authentic scientific value of our country.

Dicha gestión está regulada por un marco jurídico muy antiguo que impide la recuperación o el reciclaje en casi todas las fases del circuito de recolección, transporte y disposición final. En forma paralela a la gestión oficial, se ha extendido una vía de recolección y recuperación informal, que ha llevado a cabo algunas personas pertenecientes a los sectores más pobres de nuestra sociedad, quienes encuentran en la venta de los residuos recuperados un camino para su supervivencia diaria. En el presente artículo describimos las características de este circuito informal en la Ciudad de Buenos Aires, las rutas, calles, horarios y tipos de residuos recogidos, y analizamos el fenómeno no solamente como una manifiestación de la pobreza, sino como un camino alternativo para la recolección diferenciada de los residuos sólidos de la ciudad.

    Full Text Available En las primeras tres décadas del siglo XX, y al calor de los cambios urbanos que harían de Buenos Aires una metrópolis, la poesía, el cine, el teatro y las letras de tango trabajaron con insistencia la trayectoria protagonizada por la muchacha de barrio que, lanzándose al mundo de la noche y el cabaret del centro, apostaba a sacar ventajas de una sociedad donde el ascenso social, limitado pero real, era parte de la experiencia urbana. Las letras de tango, escritas mayoritariamente por hombres, hablan de ese viaje en clave de condena, y la tuberculosis aparece como la materialización de un castigo para esas mujeres jóvenes que han osado desafiar su lugar en el mundo doméstico y barrial. Así, el tango ofrece a su audiencia no sólo un registro fuertemente moralizante sino también la imagen de una enfermedad que parece ser exclusivo patrimonio femenino cuando, en realidad, se trataba de una enfermedad que afectaba tanto a hombres como a mujeres.

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

    This paper is introducing Buenos Aires’ achievements and challenges in implementing comprehensive development and integrating efficient and sustainable transport system within its urban structure. There are several important steps in this process starting from urban regeneration of Puerto Madero, the introduction and then implementation of a strategic plan Modelo territorial (2010) and of Buenos Aires’ Plan de Movilidad Sustentable (2013). The last one - Sustainable Mobility Plan helped Buenos Aires win several prestigious rewards for innovative approach to mobility and sustainable transport and leadership in combating climate change. Buenos Aires City government demonstrates strong leadership by implementing well-planned (Bus Rapid Transport) BRT solutions, stressing the importance of political will and support, flexibility and an open mind in listening to the points of view of all stakeholders involved. Buenos Aires has made a very important step toward sustainability by supporting development of more sustainable modes of transport, such as bicycle-sharing system and improving walkability of the city centre. The last initiative combined with strong focus on public spaces is adding to tourist attractiveness based on diversity of the capital of Argentina.

    The work performed since 1993 on the study of the elemental profile of Buenos Aires atmosphere is presented. Both aerosol direct sampling and biomonitors have been used and the samples have been analyzed mainly by Instrumental Neutron Activation Analysis (INAA). Due to problems with XRF, Anodic Stripping Voltammetry has been chosen for lead determination and Ion Chromatography for soluble anions. For aerosol direct sampling, analytical and sampling methods are described, as well as the sampling campaigns. Experiments have been performed for studying differences between day/night elemental concentrations along the week and a possible seasonal dependence. Some results of mass concentrations and others from INAA are presented. Sampling with the 'Gent sampler' began during August 1994 at an urban residential area of the city. The results of mass concentrations for the first 28 pairs of samples are shown together with some INAA results, as this is the only technique used for the analysis. Lichens and tree bark were the chosen biomonitors. Sampling and analytical methods by INAA are exposed, presenting some of the results that have been obtained.

    Little data exist about the prevalence of psycotherapy used by the general population of the city of Buenos Aires. The aim of our study was to determine this prevalence, the demographic characteristics of the population that receives psychotherapy, as well as types and characteristics of these psycotherapies. A survey was conducted among 1510 inhabitants in different neighbourhoods of the city of Buenos Aires. During the month previous to the survey, 15.6% of the population received psychotherapy treatment, 21% during the last year and 41.6% had received before. Psychoterapy treatment is more prevalent among women and people with higher educational and social-economic level, and it is less frequent in the elderly group. No differences in the use of psychotherapy exist according to marital status. Forty four percent of the patients under treatment at the moment of the survey were unaware of the type of psychotherapy received, 41.3% knew that they were receiving psychoanalytic therapy and 8% cognitive-behavioral psychotherapy. Eighty-two percent of the treatments were conducted by psychologists and 11% by physicians. The use of the psychotherapy is very extended among the general population of the city of Buenos Aires.

As a subgenre, the "inquiry into the metropolis" foregrounds the affinities between a mode of figural thought, like that provided by the essay, and a material reality, like the city with its plethora of symbolic configurations through which it is possible to examine social facts.

    In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species. The information gathered revealed that 47% of the patients were under 18 years of age and had eaten basidiomes; the remaining 53% were adults who insisted that they were able to distinguish edible from toxic mushrooms. Chlorophyllum molybdites turned out to be the main cause of fungal intoxication in Buenos Aires, which is commonly confused with Macrolepiota procera, an edible mushroom. In the second place Amanita phalloides was registered, an agaric known to cause severe symptoms after a long period of latency (6-10 hours), and which can lead to hepatic failure even requiring a transplant to prevent severe internal injuries or even death, is not early and correctly treated.

  1. Melanie Klein in Buenos Aires: beginnings and developments.

    2005-06-01

    In the first decades of the 20th century, Freud was known and quoted in Latin America by an elite of enlightened minds. In the 1940s a convergence took place in Buenos Aires of European exiles with local pioneers, and thus the Argentine Psychoanalytical Association was founded in 1942. Since then psychoanalysis has grown steadily and has spread into hospitals and universities, influencing culture at large. The socioeconomic situation of that time permitted this phenomenon to develop, to the astonishment of observers. In this paper the authors study the strong influence of Kleinian thought during the first 30 years of this development. The original works of local thinkers constitute the intellectual capital that sustains the idea of an 'Argentine psychoanalytic school'. During the 1970s, both society and psychoanalysis endured deep and complex changes. Lacan's teachings gained support and Klein's influence began to decline. At present the Buenos Aires Kleinians keep working, while their relationship with Lacanians and other schools is calmer. Respectful discussions became thus possible, oriented to strictly scientific differences.

    Mycobacterioses can produce nonspecific clinical signs in dogs and cats that make diagnosis difficult. Furthermore, the full characterization of mycobacterial agents is not always possible or practical. We characterized mycobacteria detected through cytology in 12 dogs and 7 cats with generalized clinical signs from the province of Buenos Aires in Argentina. In dogs, molecular testing confirmed the presence of Mycobacterium avium subsp. hominissuis (MAH) in 8 cases and M. fortuitum in 1 case. All dogs were Miniature Schnauzers, suggesting that this breed may be more susceptible to M. avium than other dog breeds. The cat isolates were 2 M. bovis, 1 M. fortuitum, and 1 MAH. Mycobacterial interspersed repetitive unit-variable-number tandem repeat patterns suggested possible links with cattle, swine, and humans studied previously in Argentina. The results show that pets may act as susceptible hosts with the potential risk of transmitting the infection to humans and other animals.

  6. Eugenics in Buenos Aires: discourses, practices, and historiography.

    Since the early 1990s, a series of studies underscored the overwhelming presence of positive eugenics in modern Argentina. These works emphasized the marginal role which discourse on eugenics took on violent methods for selection. In recent years, this point of view has shifted, emphasizing the conceptual viscosity of eugenics as well as the presence of negative eugenic discourses. This paper discusses these historiographic trends, and also dwells on the narratives that those perspectives articulated in relation to the question of sterilization and regulation of marriage of those who had tuberculosis in Buenos Aires during the first half of the twentieth century. This example stresses the need to examine discourse as well as practices in understanding and making sense of the past.

    Full Text Available Abstract Studies on the political life of the poor in Latin American have rarely focused on money, although there have been works focused on the survival strategies of the poor; political clientelism; and collective mobilizations. In this article, I analyze political life in the poor neighborhoods of Greater Buenos Aires through the lens of money that circulates within the Peronist networks. I conducted ethnography fieldwork between 2006 and 2010. Does money have a legitimate role in politics? Has the monetization of political activities dissolved values, commitments, and loyalties among the poor? Is this corruption, or is this an ethical exchange among people who lack cash but possess moral capital? Here, I analyze how money becomes necessary to strengthen commitments, loyalties, obligations, expectations, and plans for both leaders and activists. Reconstructing this process can provide a foundation for the revision of place of money in political life.

    Research is a cornerstone in the training of medical doctors in any specialty, whereas it substantially contributes to good clinical practice. The aim of this study is to determine the importance of research among psychiatrists in training in Ciudad de Buenos Aires. A cross sectional descriptive study using a paper survey, which was voluntary and anonymous, was sent to psychiatrists in training in different training centers between October-November 2013. 76.6% considered research training deficient; 27.8% participated in a research project during their psychiatric training and only 21.5% presented their results at a scientific activity. 95.6% participants considered important to include research in their training. In summary, a small proportion of psychiatrists in training who participated in this study conducted research and we observed limited experience in the area, as opposed to the interest in being trained in this field.

    Austral summer (December-February) surface air temperature over southeast Australia (SEA) is found to be remotely influenced by sea surface temperature (SST) in the South Atlantic at decadal time scales. In austral summer, warm SST anomalies in the southwest South Atlantic induce concurrent above-normal surface air temperature over SEA. This decadal-scale teleconnection occurs through the eastward propagating South Atlantic-Australia (SAA) wave train triggered by SST anomalies in the southwest South Atlantic. The excitation of the SAA wave train is verified by forcing experiments based on both linear barotropic and baroclinic models, propagation pathway and spatial scale of the observed SAA wave train are further explained by the Rossby wave ray tracing analysis in non-uniform basic flow. The SAA wave train forced by southwest South Atlantic warming is characterized by an anomalous anticyclone off the eastern coast of the Australia. Temperature diagnostic analyses based on the thermodynamic equation suggest anomalous northerly flows on western flank of this anticyclone can induce low-level warm advection anomaly over SEA, which thus lead to the warming of surface air temperature there. Finally, SST-forced atmospheric general circulation model ensemble experiments also demonstrate that SST forcing in the South Atlantic is associated with the SAA teleconnection wave train in austral summer, this wave train then modulate surface air temperature over SEA on decadal timescales. Hence, observations combined with numerical simulations consistently demonstrate the decadal-scale teleconnection between South Atlantic SST and summertime surface air temperature over SEA.

    Full Text Available La educación en Buenos Aires antes de la Ley de Educación Común de 1884 ha sido un tema escasamente abordado por la historiografía argentina. El objetivo del presente artículo es indagar sobre el mundo educativo porteño estudiando las escuelas de particulares en manos de ingleses, escoceses, irlandeses, norteamericanos y sus descendientes que se instalaron en la ciudad a partir de 1820. Para ello trabajamos con los avisos publicados en la prensa angloparlante de escuelas inglesas, los registros policiales y el Censo Nacional de Escuelas de 1872 así como con opiniones de angloparlantes sobre los niños y la educación de los hijos de extranjeros. A través del estudio de estas fuentes encontramos que las escuelas inglesas formaron parte del heterogéneo mundo educativo porteño y desempeñaron un lugar destacado en la educación de la población tanto de extranjeros como nativos. Estas ofrecían una educación con asignaturas variadas y de mayor complejidad que las escuelas públicas y las de otras particulares llegando a educar a miembros destacados de la sociedad local presentándose como una alternativa al sistema educativo estatal precario o inexistente durante buena parte del siglo XIX.

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

    The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

    Excessive sun exposure is the major environmental factor in the development of skin cancer. Adolescents who play outdoor sports are highly exposed to ultraviolet rays, which will result in cumulative photodamage with a higher risk of developing skin cancer in adulthood. 1) To evaluate sun protection habits in Buenos Aires adolescent athletes. 2) To identify the characteristics of those adolescents who have developed sunburns. An observational descriptive cross-sectional study was carried out using a voluntary anonymous written and self-reported survey addressed to adolescent athletes aged 11 to 18 years, who participated in a competitive sporting activity. The study included 554 adolescents. The 26% reported to have taken sunscreen to the competition. The 5.2% reported to have used it on a routine basis during training, and the 6.1% while doing sports. The 45% of the adolescents referred that sun protection factor rating was not relevant to them. Males most frequently inclined to believe that a good suntan was synonymous of health and women believed that suntan was synonymous of beauty. Most adolescents (73%) had developed at least one sunburn in the previous summer. In this study, a low compliance with the use of sunscreen was observed in adolescent athletes, despite the high rates of sunburns they had had recently. Nowadays, sun protection campaigns addressed to this age group are urgently needed.

    Full Text Available This essay explores the Asian trade and consumption of textile and ceramics in the Government of Tucuman and Buenos Aires in the Eighteenth century. The Chinese textile «boom» that entered from Lima towards the southern space between 1700 and 1740 is analyzed. In second place, the entry of Chinese ceramics through Buenos Aires port in the second half of that century is explained. Finally two culture waves are recognized in the region: the first one tended to an «europeanization» of the Chinese objects; the second one involved the «orientalización» of the european objects.El ensayo explora el comercio asiático y el consumo de su tejido y cerámica en la gobernación de Tucumán y Buenos Aires en el siglo XVIII. Se analiza el «boom» de los tejidos chinos que ingresaron por Lima hacia el espacio austral entre 1700 y 1740. Por otra parte, se explica el ingreso de loza china por el puerto de Buenos Aires en la segunda mitad del siglo. Finalmente, se reconocen dos oleadas culturales en la región: una primera tendiente a la «europeización» de artículos chinos; y una segunda que implicó la «orientalización » de los productos europeos.

    Thermal stress may seriously affect human health to the extent of provoking death in those human groups at high risk such as little children and elderly persons. This research studies the climatology of the relative strain index (RSI) in the city of Buenos Aires (Argentina). It is observed that the conditions at 1400 hours local time on more than 75% of summer days cause discomfort, though only on 25% of days are physiological failure levels reached. The nocturnal RSI values show 75% of nights to be comfortable, bringing relief and allowing physiological recuperation. Comparison between the RSI frequency distributions of different decades by the application of the Kolmogorov-Smirnov test shows a possible urban heat-island effect that increases nocturnal RSI values. The relationship between the RSI and the daily number of interments is also analysed. Because of the large number of different causes of mortality, only about 10% of the variance of the daily number of interments can be explained by the RSI value at 1400 hours local time 1 or 2 days before. Comparison of mortality figures with these RSI values shows deaths to be at a minimum for the interval 0.0-0.1 (the RSI comfort range), slightly increasing for negative values that could represent unexpected Summer cold waves. For values of RSI over 0.2 the increment is more abrupt, indicating an impact of a thermal strain on mortality. The relationship between the joint occurrence of the 1400 hour and 0200 hour (local time) RSI values and mortality shows a clear impact of prolonged exposure to uncomfortable conditions.

To do this, we will analyze the political and economic context in which contraband arose and gained importance in order to reflect whether this economic practice -conducted by government officials, vecinos (official residents and settlers of the port of Buenos Aires- can be considered corrupt in the context of the period studied. We will situate the behavior of these social actors within an intertwined complex of political beliefs and ideologies, and conjunctures, to explain how a practice like colonial-era contraband has multiple, tightly related causes.

    The late nineteenth century saw the establishment of a sanitation authority in Buenos Aires, grounded on the ideas of nineteenth century hygienics. The article focuses on the scientific, technical and political innovations that were introduced and on the role that the process of medical professionalization played within this institution. The features of the sanitation policy that came to prevail in Buenos Aires at the turn of the century helped shape a system of standards and archetypes regarding the human body and its physical and mental well-being.

    Lead pollution present in atmospheric aerosols in the city Buenos Aires was measured in 1989, using Heavy Ion PIXE. Since then, environmental conditions have changed significantly. The usage of unleaded gasoline was introduced, and the utilisation of compressed natural gas as car fuel has increased. Recently, a new sampling campaign of atmospheric aerosols has started, partly in collaboration with the Greenpeace Foundation. The present studies reveal that lead pollution in Buenos Aires has significantly decreased since 1989. The concentrations of other elements are determined as well. (author)

    The eruption in June 2011 of the Puyehue-Cordón Caulle Volcanic Complex in Chile impacted air traffic around the Southern Hemisphere for several months after the initial ash emissions. The ash deposited in vast areas of the Patagonian Steppe was subjected to the strong wind conditions prevalent during the austral winter and spring experiencing resuspension over various regions of Argentina. In this study we analyze the meteorological conditions that led to the episode of volcanic ash resuspension which impacted the city of Buenos Aires and resulted in the closure of the two main airports in Buenos Aires area (Ezeiza and Aeroparque) on 16 October 2011. A relevant result is that resuspended material (volcanic ash plus dust) imprints a distinguishable feature within the atmospheric thermodynamic vertical profiles. The thermodynamic soundings show the signature of "pulses of drying" in layers associated with the presence of hygroscopic ash in the atmosphere that has already been reported in similar episodes after volcanic eruptions in other parts of the world. This particular footprint can be used to detect the probable existence of volcanic ash layers. This study also illustrates the utility of ceilometers to detect not only cloud base at airports but also volcanic ash plumes at the boundary layer and up to 7 km altitude. Aerosol properties measured in the city during the resuspension episode indicate the presence of enhanced concentrations of aerosol particles in the boundary layer along with spectral signatures in the measurements at the Buenos Aires AERONET site typical of ash plus dust advected towards the city. The mandatory aviation reports from the National Weather Service about airborne and deposited volcanic ash at the airport near the measurement site (Aeroparque) correlate in time with the enhanced concentrations. The presence of the resuspended material was detected by the CALIOP lidar overpassing the region. Since the dynamics of ash resuspension and

This population is considered "in danger of extinction", while the Malvinas (Falkland Islands population is in well conservation status, with an estimated size of 40,000 birds. The aim of this work is to contribute with updated information about the ruddy-headed goose's population wintering in southern Buenos Aires province. The specific objectives were to better delimit its wintering area, to look for sites with large numbers, to study its habitat used, and to identify main threats to the species. Two intensive surveys were conducted during the austral winter of 1999. The results: (1 confirm the low abundance of the ruddy-headed goose supporting its critical conservation status, (2 corroborate its very restricted distribution, with more than 80 % of sightings concentrated in an area of 13,000 ha in southern Buenos Aires province, and (3 suggest that changes in the species' habitat use during the wintering season appear to be a response to changes in habitat availability, resulting from the growth of crops and pastures. The overlap between the species wintering distribution and the main wheat cropping areas of Argentina results in serious threats to this goose. Management actions are discussed to contribute to the conservation of this endangered species.La población continental del Cauquén colorado (Chloephaga rubidiceps cría en el sur de la Patagonia e inverna en el sur de la provincia de Buenos Aires (Argentina, con un tamaño poblacional estimado recientemente en alrededor de 900 individuos.

In Buenos Aires they trade on the streets. This activity was initiated mainly by the Senegalese community.This article aims to expose the stereotypes and the relationships between the Argentine society and the African migrants in order to observe the reception of an unknown population in that part of the continent. To do this research, the ethnographic method and discourse analysis were used. The recent nature of the African migration to Argentina generates clichés and prejudices but the desire for exoticism also gives rise to fascination.

    Full Text Available The paper examines the appropriation of public space and the proposal of new urban imaginaries by the practitioners of popular cultural practices. We focus on the development and spatial expansion of Afro-Uruguayan candombe in Buenos Aires. The reterritorialization of this musical practice requires at first embedding it in the historical neighborhood of the city and appealing to the memory of Black presence in the area. The reference to this memory, and the ulterior expansion of candombe to other neighborhoods, imply a work of imagining the city that challenges the dominant image of Buenos Aires as White, modern and European. Defying this image and proposing alternative urban imaginaries, practitioners of candombe establish conflictive interactions with different social agents and actors.

    Full Text Available The history of Buenos Aires theatrical production shows different experiences of political and popular theatre that developed ways of intervention in public space. One of these experiences is Community Theatre, a “theatre of the community, for the community” that appears in the 80s with the return of democracy. Since then, Community Theatre has expanded its practice throughout the city of Buenos Aires. This article analyzes, from an anthropological perspective, the “cultural performance” of one of these groups called Matemurga de Villa Crespo. It looks into the ways this group appropriates public space, the expressive and communicative resources used in their performances and the representations that the actors build. Thus, it also examines political dimensions in these artistic expressions.

    This qualitative study of low-income mothers in Buenos Aires, Argentina, examines the influence of socio-economic conditions, organizational structures, family relationships, and food insecurity on child feeding practices and weight status. Thirty-eight mothers of preschool children living in urban Buenos Aires participated in four focus group discussions. The results indicated that many mothers were aware that obesity may be detrimental to the child's health, but most of them are unclear about the specific consequences. Maternal employment, family pressures, food insecurity and financial worries seem to influence child feeding practices. These findings have important implications for developing strategies for nutritional assistance that could benefit the health of children and provide opportunities for educational programs that are directed to nutritional awareness in Buenos Aires, Argentina. The right to eat regularly and properly is an obligation of the State and must be implemented taking into account the notion of food sovereignty and respecting the importance of preserving the culture and eating habits of a country and its diverse population groups.

    Casarin, Ariel; Delfino, Maria Eugenia

    2010-09-15

    This paper examines the determinants of residential electricity demand in the Greater Buenos Aires between 1997 and 2006. During the second half of this period, residential tariffs remained nominally fixed, while an income boom boosted up the sales of durables. This study differs from previous works in that it explicitly considers the impact of the stock of air-conditioners on residential demand. The paper reports short- and long-run elasticities and examines the contribution of prices and durables to recent demand growth. Simulations illustrate the impact of prices and durables on future demand.

  9. Gaseous elemental mercury in the marine boundary layer and air-sea flux in the Southern Ocean in austral summer.

    Gaseous elemental mercury (GEM) in the marine boundary layer (MBL), and dissolved gaseous mercury (DGM) in surface seawater of the Southern Ocean were measured in the austral summer from December 13, 2014 to February 1, 2015. GEM concentrations in the MBL ranged from 0.4 to 1.9ngm -3 (mean±standard deviation: 0.9±0.2ngm -3 ), whereas DGM concentrations in surface seawater ranged from 7.0 to 75.9pgL -1 (mean±standard deviation: 23.7±13.2pgL -1 ). The occasionally observed low GEM in the MBL suggested either the occurrence of atmospheric mercury depletion in summer, or the transport of GEM-depleted air from the Antarctic Plateau. Elevated GEM concentrations in the MBL and DGM concentrations in surface seawater were consistently observed in the ice-covered region of the Ross Sea implying the influence of the sea ice environment. Diminishing sea ice could cause more mercury evasion from the ocean to the air. Using the thin film gas exchange model, the air-sea fluxes of gaseous mercury in non-ice-covered area during the study period were estimated to range from 0.0 to 6.5ngm -2 h -1 with a mean value of 1.5±1.8ngm -2 h -1 , revealing GEM (re-)emission from the East Southern Ocean in summer.

En cuanto oportunidad de intercambio y discusión, este encuentro permitió la organización del trabajo de los cineastas y focalizó el debate en tres ejes principales: la contribución del cine a los procesos de liberación nacional, la descolonización de las pantallas del Tercer Mundo y la lucha contra la «alienación cultural». El resultado más importante fue la creación del Comité de Cine del Tercer Mundo. Solo seis meses más tarde, un nuevo encuentro tuvo lugar en Buenos Aires (Argentina.

    A prototype for an integrated system that includes air quality constraints to the procedure that is presently in use to determine the daily economic dispatch of power plants in Argentina is proposed. The recent incorporation of new machines to the installed capacity of the three power plants located in the densely populated metropolitan area of Buenos Aires, the thermal-based future expansion of the power sector and the relatively high nitrogen oxides concentrations that can be associated to electricity generation in the city of Buenos Aires, served to motivate this work. The prototype attempts to generate a dispatch that is compatible with the environment taking into account the present economic dispatch, weather forecast and dispersion models to evaluate ambient air concentrations of nitrogen oxides (NO x ) caused by the combined operation of the thermal power plants. Although the prototype deals exclusively with NO x , since these are the pollutants of primary concern considering the fuel consumption pattern of argentinean power plants, its structure is general enough to take into account other pollutants such as sulfur dioxide and particulate matter.

    Full Text Available The Hospital de Clínicas organized a free program of goiter detection by palpation. This campaign was aimed at the population of the metropolitan area of Greater Buenos Aires (11 million inhabitants, with the prerequisite that each participant should be quite unaware whether he/she was a carrier of any thyroid disease. Attendees were split into two groups, i.e., Random and Induced. The former consisted of 542 individuals who came to consultation due to mere curiosity, while the latter involved 500 subjects, comprising consanguineous family members of patients with thyroid disorders and also individuals who suffered from other ailments. Ages ranged from 2 to 85 years. In the Random Group, goiter prevalence of 8.7% was observed, while in the Induced Group it climbed to 14.4%. Since both groups were mostly made up of women (87.2%, a correction based on the masculinity index was applied to members of the Random Group. Thus, the total observed prevalence of goiter was 6%, diffuse goiters corresponding to 3.5% and nodular ones to 2.5%. The frequency of nodules increased with age, 90.5% occurring in those over 40 years. In the Induced Group, goiter prevalence among relatives of patients with thyroid disorders proved to be 13.1%, rising to 17.8% in those who suffered from other complaints. The epidemic data presented herein are the first arising from a screening survey carried out in a large iodine-sufficient population of the southernmost tip of the American continent. These results are useful to build up the world map of goiter prevalence in non-endemic areas.El Hospital de Clínicas organizó un programa gratuito para la detección de bocio por palpación.

    Bats are potential reservoirs of many vector-borne bacterial pathogens. The aim of the present study was to detect species of Anaplasma, Ehrlichia, Neorickettsia, Rickettsia, Borrelia and Bartonella in Brazilian free-tailed bats (Tadarida brasiliensis, Molossidae) from Buenos Aires city, Argentina. Between 2012 and 2013, 61 T. brasiliensis from urban areas of Buenos Aires city were studied. The samples were molecularly screened by PCR and sequencing. Five bats (8.2%) were positive to Neorickettsia risticii, one (1.6%) was positive to Rickettsia sp. and three bats (4.9%) to Bartonella sp. For molecular characterization, the positive samples were subjected to amplification and sequencing of a fragment of p51 gene for N. risticii, a fragment of citrate synthase gene (gltA) for Rickettsia genus and a fragment of gltA for Bartonella genus. Phylogenetic tree was constructed using the maximum-likelihood method. Phylogenetic analysis of N. risticii detect in our study revealed that it relates to findings in the USA West Coast; Rickettsia sp. detected is phylogenetically within R. bellii group, which also includes many other Rickettsia endosymbionts of insects; and Bartonella sp. found is related to various Bartonella spp. described in Vespertilionidae bats, which are phylogenetically related to Molossidae. Our results are in accordance to previous findings, which demonstrate that insectivorous bats could be infected with vector-borne bacteria representing a potential risk to public health. Future research is necessary to clarify the circulation of these pathogens in bats from Buenos Aires. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The prevalence of Molar Incisor Hypomineralization (MIH) still remains unknown in Argentina. The objectives of this work were to: estimate prevalence of MIH in a group of children seeking dental care in the city of Buenos Aires, analyze distribution according to year of birth and compare prevalence and severity of MIH in children with different access to health care services. A prospective, observational, transversal, descriptive study was designed, to be conducted on children seeking attention at Department of Comprehensive Children's Dentistry at the School of Dentistry of Buenos Aires University and at 3 pediatric dentistry offices attended by members of the team, located in Buenos Aires city (Kappa 0.933 0.911-0.952), from April to August 2010. The study included all children born between 1993 and 2003, whose 4 first molars and 8 permanent incisors had erupted. After prophylaxis and drying, the teeth were clinically evaluated and specially designed charts were used to record sex, year of birth, type of access to dental care, presence of MIH, number of affected incisors and molars, and maximum degree of severity for each tooth. The data obtained were analyzed using percentages, Fisher's Exact Test and Linear regression. 1098 children, mean age 11.3 years (11.08-11.39) were evaluated. Prevalence of MIH in this study was 15.9% (13.8-18.2). A highly significant positive correlation was obtained between MIH and year of birth (pprevalence was 24.40% (20.9-27.9) while in Group B it was 6.44% (4.31-8.56) (pprevalence and degree of severity of MIH.

    The episodes of bronchial obstruction at early age constitute a frequent problem in Pediatrics. The aim of this study was to evaluate the prevalence of recurrent wheezing in infants in Buenos Aires City, as well as to identify any associated factors. Cross-sectional study performed from 2011 to 2012 in the Children Hospital Ricardo Gutiérrez, Buenos Aires City, as part of the International Study of Wheezing in Infants. A validated questionnaire was applied to parents of infants aged between 12 and 15 months. The prevalence of wheezing, mostly the recurrent episodes (three or more), and their probable associated factors were evaluated. Data were statistically analyzed with χ 2 , Fisher's test, binary and logistics multiple regression analysis. The significance level was 0.05. Over 1063 infants, 58.9% (confidence interval (CI) 95% 55.9-61.9) presented at least one episode of wheezing and 26.3% (CI95% 23.8-29.9) three or more episodes (recurrent wheezing). Risk factors associated to wheezing were male gender (p=0.001), six or more episodes of cold during the first year of life (p <0.0001), age at first cold <4 months (p <0.0001); pneumonia (p <0.0001) and smoking during pregnancy (tobacco) (p=0.01). For recurrent wheezing, risk factors we considered as six or more episodes of cold during the first year of life (p <0.0001), early (< 4 month of age) onset wheezing (p <0.0001) and nocturnal wheezing (p <0.0001). The prevalence of recurrent wheezing among infants in Buenos Aires Ciy was high (26.3%). Some identified associated factors can be preventable.

    Full Text Available The Judicialization of the Struggle for Access to Housing in Buenos AiresThis paper addresses the analysis of a new yet scarcely considered phenomenon in the field of studies concerning protests in Argentina in particular, and in Latin America in general: the judicialization of social demands. One particular example of this phenomenon centres on the major role that slums have played in the struggle for housing in Buenos Aires City during the past decade. The analysis is based on a case study of the judicialization of the demands of a new informal urban settlement called Playon de Chacarita. Drawing from the findings of this research, the article reflects on some of the recent transformations in Argentine society and the effects these are having on the expression of politics of low-income classes. It also offers some perspectives on the challenges that the poorest urban sectors are currently facing in demanding the realization of their rights.Resumen: Este artículo se aboca al análisis de un fenómeno novedoso y escasamente examinado en el campo de los estudios sobre la protesta en Argentina, y en América Latina en general: la judicialización de los reclamos sociales.

    Full Text Available Hydatidosis is a parasitic infection caused by the tapeworm larva of Echinococcus spp. Its relevance lies in its wide distribution, great number of clinical cases and outstanding morbility. Hydatid infection of the orbit comprises far less than 1% of the total incidence. This is a case of a patient from Argentina complaining of a two-week evolution proptosis of the right eye. A microscopic examination revealed the presence of protoscolices of Echinococcus spp. in the fluid obtained during the surgical proceedings. The patient was treated with oral albendazole. To our knowledge, this is the first case of occular hydatidosis diagnosed in the city of Buenos Aires, Argentina.

    We have sought to adapt and validate a NART-like Spanish test, the Word Accentuation Test (WAT: Del Ser, Montalvo, Espinosa, Villapalos, & Bermejo, 1997) to estimate acquired intelligence in local normal older adults. The test requires examinees to read aloud infrequent, irregularly stressed Spanish words, a situation that presumably requires lexical knowledge. Results in a sample of 74 participants show that the revised WAT (i.e., the WAT for Buenos Aires) has good concurrent validity with the WAIS Vocabulary subtest and number of years of formal education, as well as high internal consistency. Performance on this test was dissociated from age, memory, or frontal/executive measures.

    2012-01-01

    This paper explores the medical-legal discourse around female prostitution that was articulated in Buenos Aires during the first decades of the 20th century. It focuses on the use of different ideological resources and on the policies and laws that were introduced to gain control over the sex trade and describes parallelisms between prostitution, disease and crime. In fact, the capital of Argentina was internationally known as a centre of prostitution and white slave trafficking, and Jewish participation in these activities allowed the consolidation of xenophobic theories. Medicine and law, among other disciplines, made important inputs into a simplified approach to this problem.

    1994-01-01

    Buenos Aires city and its surroundings, has a huge population and very dense traffic. There are many possible pollution sources that can be identified, but other characteristics such as weather and location counteract some of these sources to the benefit of the atmosphere of the city. Although several groups have been working on these subjects, there is not enough information about which elements are present in Buenos Aires air. The aim of this project is to provide information about the elemental profile of the atmosphere of the city and to evaluate and to make an interpretation of the obtained data. Both XRF and INAA are going to be used for analyzing the air filter samples with the participation of the Meteorological Service in sampling and interpretation of the results. By choosing adequate sampling sites and times, differences between day/night, week day/weekend will be looked for. The influence of non-leaded petrols will be studied. Some work on air samples was done before the beginning of this contract to settle future working conditions. Some results from this study are presented only as preliminary ones. Sampling will begin during this April at two sites with different traffic density. For both XRF and NAA suitable standards will be prepared. Medium and long lived nuclides are going to be analyzed by INAA. Plans for 1993 are given as well as possible collaboration with other groups in the country. (author). 3 refs, 1 tab

This presentation focuses on winter season and furtherly investigates the detailed advection and cloud-radiation processes and teleconnections from tropical sea surface temperature anomalies (SSTA) combining statistical analysis with Rossby wave dynamics and modelling experiments. The EOF1, featured with the anomalous center in the central part, is related to the tropical eastern Pacific SSTA, which may impact on the SA SAT variability through the Walker circulation and a regional Hadley cell. The anomalous center is largely attributed to low-level advection transported by the Hadley cell. The EOF2, as a fluctuation between anomalies in the southeast Brazil and the southern tip, is related to the SSTA surrounding the Maritime Continent, which may generate a barotropic wave train propagating to the SA continent. This wave train can strengthen high latitude westerly flow transporting warm advection to the southern tip, and generate southeast anomalous flow transporting cold advection to the southeast Brazil. Meanwhile, the cloud-radiation processes are also involved to enhance the advection-induced SAT anomalies in both areas.

    Biomonitors were used as part of a pollution study of Buenos Aires city atmosphere under the International Atomic Energy Agency Research Contract ARG 7251, from the Co-ordinated Research Programme on Applied Research on Air Pollution using Nuclear Related Analytical Techniques. Lichens were primarily selected as indicators. Two different approaches were conducted, direct sampling of Parmotrema reticulatum, at a few places and the use of lichen bags, filled with Usnea sulcata from a northern national park, and hung at different sites. Simultaneously, tree bark was tried as biomonitor. Platanus acerifolia and Melia azedarach were selected as candidates, for being the most common trees in the city, but only P. acerifolia was analyzed. All the samples were analyzed using instrumental neutron activation analysis at the Ezeiza Atomic Centre of the National Atomic Energy Commission. RA-3) reactor was used for the irradiations, determining: As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn. Concentration values for P. reticulatum compared well with values from literature. For U. sulcata differences were found among the tested sites and also, for some elements an increasing trend with time was observed. Enrichment factors calculated using Sc as reference and Mason's crustal average concentrations showed vehicules and refuse incineration as contributing sources to the aerosol. Tree bark from Buenos Aires and from a smaller city with mainly agricultural activities were analyzed and the results are coincident with those from lichens. This work is the first and preliminar contribution to the study of Buenos Aires aerosol using biomonitors. (author)

    Full Text Available This issue resulted from empirical and comparative research, in Rio de Janeiro and Buenos Aires. It discusses different kinds of lawyers’ actuation in mediation. In Rio, this actuation suffers resistance. In Buenos Aires, it is broader and viewed in a positive way. There is, however, a common feature: the expectation about a specific way of "being a lawyer”. They distinguish "good lawyers" from those considered "inappropriate" for this job. This valuation is associated with two categories: collaborative or combative lawyers. Interviews and observations showed that lawyers are essential if they can cooperate to rescue the understanding between the parties.

    To assess the level of equity in drug consumption patterns in the Metropolitan Area of Buenos Aires, Argentina, given the transformation of the Argentine pharmaceutical market since the deregulation of the country's economy in 1991. For this study, data from secondary statistical sources were processed and analyzed. The secondary sources used were two household surveys that contained a module on the utilization of health services and the associated expenditures. The surveys had been designed by the Ministry of Health and were applied in the Metropolitan Area of Buenos Aires in 1989 and 1995. There was a socially regressive increase in out-of-pocket expenditures on drugs between 1989 and 1995, in a market where average drug prices doubled in the midst of relaxed price controls and more open imports. The regressive character of drug expenditures was shown in the growth in direct spending for drug purchases, the increase in the proportion of private health expenditures devoted to drugs, and the unequal increase among the different economic strata in the proportion of family income going toward drugs. Out-of-pocket expenditures on drugs are an efficient indicator of equity for studying the financial protections that urban Argentines have when they become ill. This kind of indicator of financial equity could help improve the regulatory framework of the pharmaceutical market by incorporating social evaluation criteria along with analyses of pharmaceutical safety and therapeutic efficacy.

    Childhood overweight has been reported in developing countries. The World Health Organization (WHO) has recommended a standardized classification system in order to facilitate comparison across countries and studies. This study aims to assess the prevalence of overweight, obesity and thinness in a group of 10-11-year-old children using three references [the Center for Disease Control (CDC) 2000, the the International Obesity Task Force (IOTF) 2000 and the WHO, 2007]. A representative sample of 1588 children (771 boys and 817 girls) resulted from the randomization of 80 public schools from Buenos Aires. The prevalence of overweight, including obesity, for the whole sample was 35.5, 27.9 and 27.9%, respectively, depending on the reference used. For overweight, no gender differences were observed regardless of the reference used. Obesity was significantly more frequent among boys, and this remained consistent for the three references. Thinness frequency was 1.6 and 2.5% for the boys and 2.7 and 4.5% for the girls when considering the WHO and CDC cut-off points, respectively, and frequency increased in both boys and girls for each age group. There is a high prevalence of overweight and obese cases among school-aged children of Buenos Aires regardless of the reference used. Epidemiological data provided by this study suggests the urgent need to design preventive interventions.

    Full Text Available During the second half of the XXth century, Argentina went through the last attempts at a policy of long time tradition, known as agricultural colonization. Usually, lands in the pampa zone were selected, with a traditional productive and agro-export relevance. Nevertheless, certain periurban areas of the cities of Buenos Aires and La Plata became of interest because of their highly productive soil, their location near major urban centers, and their capacity to house families. These areas have not been studied carefully and need to be explored. With this study we look into the situation of the families that lived in this speciic context, addressing their multi-ethnic origins, trajectories, work methods, and social practices. With this purpose, we selected two communities: “La Capilla” (Florencio Varela, southern zone, Gran Buenos Aires and “Justo José de Urquiza” (La Plata, capital city of the province. We found that these communities were consolidated by the formation of formal and informal societies, characterized by the participation of the families and subjects who contributed to the community through their roles and practical knowledge. It was found that children played a particularly important role as social subjects, articulating the different spaces in which their families lived.

Prospective descriptive study undertaken by the Hospital Cosme Argerich s Vertical Transmission Working Group, Buenos Aires city, Argentina 1998-2008. Periods 1998-2003 vs. 2004-2008 were compared and variables associated with vertical transmission identified. Of 357 MCB, 21.0% of the mothers had HCV coinfection and 68.0% CD4 vertical transmission was 3.3% (10/302). Comparing both periods, an increase in triple ARV and VL vertical transmission for 2004-2008 was 1.3% vs. 6.3% in Buenos Aires city (official statistics). Absence of maternal/intrapartum prophylaxis and prematurity were associated with vertical transmission (P vertical transmission between the two periods was observed attributable to increased coverage of maternal/neonatal ARV administration and increased use of triple therapy. The absence of maternal/intrapartum prophylaxis was the main factor associated with vertical transmission, emphasizing the need to improve accessibility of MCB to the local public health system.

Based on documents contained in the Artigas Archive, local press entities and governmental files from the General Archive of the Nation, it is possible to trace some of their activities and identify some of their political plans. Together, this evidence calls into question the strong image provided by federal historiography, which holds that there were no Artiguist ideas in the province during the early revolutionary war years.

    Streptococcus equi subsp. equi is the etiologic agent of strangles, an infectious disease affecting the upper respiratory tract and head and neck lymph nodes of equines. Routine antimicrobial therapy includes penicillin (PEN) as antibiotic of first choice. Streptococci are usually susceptible to PEN and only a few antimicrobial studies had been performed. The aim of this work was to study the antimicrobial susceptibility profile of S. equi from Buenos Aires, Argentina. Ninety-two isolates were studied by the single disk method to PEN, cefotaxime, erythromycin (ERY), tetracycline, enrofloxacin (ENR), trimethoprim sulfamethoxazole (TMS), ciprofloxacin, clindamycin (CLI), streptomycin (STR) and florfenicol. Minimum inhibitory concentration (MIC) to PEN and antibiotics with resistance and intermediate susceptibility were tested. High percentages of susceptibility were obtained by the disk diffusion method and MIC values of PEN, TMS and CLI were found to be under the breakpoint values. Resistant strains of ENR and STR with MIC 50 , MIC 90 and MIC ranges above breakpoints were identified. These findings confirm that PEN may be used empirically because resistant strains were not found in Buenos Aires. Emphasis is placed on the rational use of antibiotics to achieve therapeutic success, to prevent chronicity, recurrence of infections and the emergence of resistance.

    2017-08-01

    Full Text Available In the past two decades, Buenos Aires has witnessed a surprising growth and popularity of Afro-Latin American cultural practices. Foremost among them, and most visible in the city’s public space, is Afro-Uruguayan candombe. Having spread beyond the Uruguayan immigrant community that contributed to its re-localization in the 1970s, it is nowadays widely part of the youth urban culture along the country. The paper discusses the re-significations following this vigorous development and how it intersects with other social processes of contemporary Argentine society. Focusing on the re-signification of candombe as “resistance”, as performed by a collective of drummers and dancers known as “Los Tambores No Callan” (Drums cannot be silenced, it highlights the connections they establish between this cultural practice and politics as social struggle. It suggests that this cultural practice is part of –and helps shape– new activist ethos in the public space of Buenos Aires, a historically alleged “White” and “European” city.

    Full Text Available The context in which ageing is occurring in Latin America and the Caribbean countries raises questions about future trajectories in the prevalence of disabilities by age. In this sense, it is of great importance to study the behaviour of the prevalence of disabilities and analyse the risk factors in populations of the region. The aim of this study is to analyse the prevalence of disabilities among the individuals 60 years and over in Buenos Aires and to evaluate the differences between groups with different educational levels. The data used come from the study "Health, Welfare and Aging"-SABE (Spanish acronym- for Buenos Aires. Based on this information, we estimate the prevalence of disabilities by level of education and we analyse the effects of different risk factors on the likelihood of experiencing disability among individuals with different levels of education. The results suggest that educational level acts as a major protector against the risk of experiencing disabilities in ADL and IADL and the relationship would be partially mediated by health profiles of the individuals.

    Full Text Available Lago General Carrera (Chile also called Lago Buenos Aires (Argentina or originally Chelenko by the native habitants of the region is located in Patagonia on the Chilean-Argentinean border. It is the largest lake in Chile with a surface area of 1850 km2. The lake is of glacial/tectonic origin and surrounded by the Andes mountain range. The lake drains primarily to the Pacific Ocean to the west, through the Baker River (one of Chile's largest rivers, and intermittently eastward to the Atlantic Ocean. We report ongoing results from an investigation of the seasonal hydrological cycle of the lake basin. The contribution by river input through snowmelt from the Andes is of primary importance, though the lack of water input by ungaged rivers is also critical. We present the main variables involved in the water balance of Lake General Carrera/Buenos Aires/Chelenko, such as influent and effluent river flows, precipitation, and evaporation, all this based mostly in in-situ information.

    Full Text Available En las primeras tres décadas del siglo XX, al calor de los cambios urbanos que harían de Buenos Aires una metrópolis, la poesía, el cine, el teatro y las letras de tango trabajaron con insistencia la trayectoria protagonizada por la muchacha de barrio que, lanzándose al mundo de la noche y al cabaret del centro, apuesta sacar ventajas de una sociedad donde el ascenso social, limitado pero real, era parte de la experiencia urbana. Las letras de tango, escritas mayoritariamente por hombres, hablan de ese viaje en clave de condena y la tuberculosis aparece como la materialización de un castigo para esas mujeres jóvenes que han osado desafiar su lugar en el mundo doméstico y barrial. Así, el tango ofrece a su audiencia no sólo un registro fuertemente moralizante sino también la imagen de una enfermedad que parece ser exclusivo patrimonio de las mujeres cuando, en realidad, se trataba de una enfermedad que afectaba tanto a hombres como a mujeres.During the first three decades of the 20th century, in the fervor of urban change that transformed Buenos Aires into a metropolis, poetry, cinema, theater, and the lyrics of the tango repeatedly portrayed the path of muchachas de barrio who, by taking to nightlife and the downtown cabarets, placed their stakes on a society where social ascent - limited yet real - was part of the urban experience. For the most part written by men, the lyrics speak of these journeys in a tone of censure, and tuberculosis is cast as a form of punishment for these young women who dared to question their place in the domestic world and the world of the barrio. The tango thus offers its audience not only a highly moralizing account but also paints an image of an illness that seems unique to women although it in fact affected male and female alike.

  14. Megacity and country emissions from combustion sources-Buenos Aires-Argentina

    Historic time series (1970-2006) emissions of greenhouse gases and air pollutants arising from stationary and mobile combustion sources were estimated at national level for Argentina and at regional level for the metropolitan area of Buenos Aires (MABA). All emissions were estimated using a bottom-up approach following the IPCC good practice guidance. For mobile sources, national emissions include all transport categories. Regional emissions account thus far only for on-road. For national emissions, methodologies and guidance by the IPCC were employed, applying the highest possible tier and using: i)country-specific emission factors for carbon and sulphur and technology-based information for other species, ii)activity data from energy balance series (1970-2007), and iii)complementary information concerning the non-energy use of fuels. Regional emissions in 2006 were estimated in-depth using a technology-based approach for the city of Buenos Aires (CBA) and the 24 neighboring districts composing the MABA. A regional emissions factors database was developed to better characterize Latin American fleets and driving conditions employing COPERT III-IV algorithms and emission factors measured in dynamometers and circulating vehicles in Argentina, Brazil, Chile and Colombia. Past emissions were back estimated from 2005 to 1970 using the best available information, which differs greatly among categories, spatial disaggregation and time periods. The time series of stationary and mobile combustion sources at the national and regional level allowed the identification of distinct patterns. National greenhouse gas emissions in 2006 amounted to ~ 150 million ton CO2-equivalent, 70% of which were contributed by stationary sources. On-road transport was the major contributor within mobile sources (28.1 %). The increasing emissions trends are dominated by on-road transport, agriculture and residential categories while the variability is largely associated with energy industries

    of the coastline was carried out during the eighties, producing a number of marinas, theme parks and reconstruction of historical sites, which tend more to the standardization that the diversification of spaces for use of citizens. But this phenomenon does not belong exclusively to the last decades of the last century. Early interventions in the urban coastal fronts began with the discovery of the coast and leisure in the mid-nineteenth century. The discovery of the coast and leisure had been born since the late eighteenth century with the loss of fear of water, the new value given to science and currents of thought of the Enlightenment and the Romanticism of the time, which would Grand Tour of Europe. This assessment of costs is not reached the industrial cities until the last decades of the 1800s. Several European cities had previously coastal walks, but these were not from a planned urban spaces shared with the port and its aim was solely that of a contemplative walk. In Buenos Aires, as in other American cases, the start of the use of the coast and leisure was very early, compared with its parallel in Europe. While in New York and Chicago Fredrick Law Olmsted and Calvert Vaux were imposing a new use of public space and urban nature in contrast to the growth of cities, Domingo Faustino Sarmiento raised the first projects for the Tres de Febrero Park, the first coastal park the city of Buenos Aires. The authorities, architects and engineers who worked on the draft coastal parks saw these spaces as places of opportunity, as horizons for action, being edges of the city provided a special place for the development of public space. From an aesthetic professionals in charge saw the horizon as a scenic attraction, while from the practical side, the waterfront was the edge, so the city and an area of conflict between national and municipal authorities.

    Full Text Available This paper addresses the implications of the theoretical approach we choose to analyze the discourses of stakeholders in qualitative fieldwork. As part of this reflection I tackled the theoretical assumptions behind “action” versus “experience articulation” analytical traditions. The evidence presented was collected from 2004 to 2014 while accompanying the design, construction and management of a “social plant” for residues classification placed on “Reconquista Area”, in northeast of Great Buenos Aires. Along this decade I combined traditional qualitative approach with action research, which permitted to register the changes and transformations in the discourses about the “social plant”. My hypothesis is that these variations can be explained not only by context´s fluctuations but transformations in social actor’s subjectivities, which are reflected both in their positions among themselves and the narratives about their own stories.

The sample was composed by 5341 cases of children and teenagers from 0 to 20 years old, whose were treated in 2010 for having been victims of maltreatment. Physical maltreatment was the most frequent one. The girls presented major proportion of sexual abuse, whereas boys registered major proportions of negligence, physical maltreatment and desertion situation. An increase of the sexual abuse frequency in teenagers from 12 years was observed. As a whole, the information demonstrates that sex and age of victims are differentially associated with different types of maltreatment, and these are pertinent variables to have into account by future investigations, and prevention and protection organisms.

    The geomagnetic field (Bgeo) sets a lower cutoff rigidity (RC) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with the MAGCOS code), we use backtrack ing to analyze particles arriving at the location of two nodes of the net LAGO (Large Aperture Gamma ray burst Observ atory) that will be built in the near future: Buenos Aires and Marambio (Antarctica), Argentina. We determine the asymptotic trajectories and the values of RC for different incidence directions, for each node. Simulations were done us ing several models for Bgeo that emulate different geomagnetic conditions. The presented results will help to make analysis of future observations of the flux of cosmic rays done at these two LAGO nodes.

I intend to focus on the reasons why squatters -unlike other precarious city inhabitants, such as the slumdwellers- become ignored by the government and are, at the same time, categorized on the basis of an aggregate of illegal factors. In fact, if this phenomenon has been regarded as such in the past years, it was due to an increasingly restrictive policy concerning this phenomenon, which was manifested not only in readily evicting strategies, but also in the dramatic lack of satisfactory housing policies for the aforementioned population.

    Full Text Available Sporadic amyotrophic lateral sclerosis (sALS is considered a multifactorial disease with genetic and environmental factors causing motor neuron degeneration. OBJECTIVE: To describe the epidemiological and occupational characteristics of patients with sALS who attended the Ramos Mejía Hospital at Buenos Aires, Argentina. METHOD: We analyzed the medical records of sALS patients diagnosed between 2001 and 2008. All occupations were coded according to the International Standard Classification of Occupation (ISCO. RESULTS: 187 patients were assessed, 38.5% were women and 61.5% men. Mean age at diagnosis was 55 years. 16% of them came from rural areas; 68% of the studied population had no health insurance. 40% were employed in elementary occupations, 19 were technicians and 8 handicraftsmen. CONCLUSION: The most represented profession was elementary occupation. A large proportion of patients came from rural areas, which might suggest an increased risk of environmental exposure to an unknown agent in those regions.

Stands of Eucalyptus viminalis Labill. were identified, with ages between 4 and 14 years-old. Twenty-one individuals were felled with diameters ranging from 9,2 to 32,5 cm. Simple and multiple regression models were developed and volume, branch leaf and stem biomass were estimated. The best volume equations were based on lineal models and the most adequate behavior was obtained with d2. To estimate leaf, branch and stem, ln-ln models have been suggested, with diameter and h or only diameter. The leaf biomass presented the weakest adjustment. The distribution of trees biomass agrees with the bibliography. The proportion of crown biomass decreases with age; on the other hand, the proportion of stem biomass increases with age.

    This analysis of the sanitary policies enforced in the province of Buenos Aires by Domingo Alfredo Mercante--Juan Domingo Perón's right-hand man--focuses on one of his most fascinating efforts: the eradication of hydatidosis. In exploring an issue largely forgotten by historiography, the article describes how the Mercante administration (1946-52) used statistical, socioeconomic, and symbolic legitimization to place hydatidosis on the State agenda. The administration's strategies are also pinpointed: the passing of regulatory laws against this endemic disease; the creation of specific state anti-hydatidosis institutions; the creation of space for information and for interdisciplinary, interministerial, and even supranational education aimed at achieving greater knowledge of the disease and at the exchange of experiences; and, lastly, the definition of initiatives focused on relief, treatment, and prevention in animals and people.

    Full Text Available The electrical macro-system of the Atlantic coast of Buenos Aires displays a form of development which differs from the drives and expectations of the global productive process and from the general social reproduction conditions that can be described as underdeveloped. Since 2003 and due to the increasing consumption of electricity, electrical supply issues have worsened and the area has started to experience a state of electricity emergence. This paper analyzes those key factors which explain such situation: the Capitalist re-structuring of the electric sector which took place during the 1990s and the way of working imposed by the regulatory framework, the political and economic changes of the Post-convertibility period, the application of an anti-crisis strategy based on palliative measures and a marked seasonality of the local electricity demand induced by the enormous tourist influx

    The Infectious Diseases Hospital Francisco Javier Muñiz, Buenos Aires, Argentina, is the oldest in Latin America. It is over 100 years old and has a history worthy of pride. It became known as "Hospital of the pests" and was preceded by the old House of Insulation, which served as a quarantine station during epidemics of cholera, yellow fever and smallpox. The new House of Insulation, built in the neighborhood of Parque Patricios ("Barracks Hospital"), was renamed in 1904 in memory of Francisco Javier Muñiz, a former military doctor, naturalist and paleontologist. Its technical name is "Porteño Care Centre and National Reference Regional Infectious-Contagious Disease". It receives numerous national and foreign undergraduate and postgraduate students in its Departments of Infectious Diseases and Respiratory Diseases.

At this hospital, there was, under the military dictatorship (1976-1983, a Clandestine Imprisonment Center, where people were kept prisoner as disappeared. Therefore, at this facility both practices of health restoration and torture and murder perpetration coexisted. Through thirty indepth interviews carried out among neighbor young people, the existence of manifold knowledge fractures and memory transmission about State violence is verified, being a result from the social relations breakthrough that used to articulate the neighborhood and the hospital, and from the material life conditions promoting undifferentiated historical and political time awareness.

    Directory of Open Access Journals (Sweden)

    Ricardo Apaolaza

    2016-09-01

    Full Text Available This paper studies how the characteristics of Latin American urban transportation generate dimensions of dispute of ‘spatial capital’, meaning an individually internalizable type of urban resource which results from the combination of objective material conditions and subjective socio-cultural conditions. These conditions determine a socially differentiated use of territory and sometimes are decisive elements in opening new niches for high-end real-estate producers and consumers, hence linking with processes of displacement and exclusion. The study cases compare four neighborhoods from Buenos Aires and Santiago de Chile, two peripherals and two pericentrals. The results show, considering the role of new infrastructure, a strong difference between residents from the peripheral cases and little difference in the pericentral cases, identifying, however, processes of a dispute over the ownership and use of urban space and the neighborhood, in all the cases.

    The physicochemical parameters (moisture, hydroxymethyl furfural, colour, electrical conductivity, free acidity, glucose, fructose and sucrose) and the sensory properties(aroma, taste, appeareance, texture) were determined in honeys from apiaries of the agricultural, hills and meadow zones of the south east region of Buenos Aires province (Argentina). The analysis of variance showed significant differences among zones in the mean value of hydroximethyl furfural, colour, electrical conductivity and sucrose content. The principal component analysis explained the 70% of the variance among samples with the first two principal components in both cases. The cluster analysis and linear discriminant analysis showed that samples were grouped in relation to the sampling region coinciding with the results of the principal component analysis. Results suggest that could be possible to classify honeys according to the geographic origin based on the physicochemical parameters; however, the sensory properties were not good predictors.

    Five hundred men who have sex with men were recruited in Buenos Aires using respondent driven sampling. Of them, 46 respondents (24 of them not gay identified) who were HIV infected were asked questions on serodisclosure. The sample was characterized by indicators of low socioeconomic status. Most of the respondents reported being in good to excellent health despite 42% of them having been diagnosed with AIDS. Only 10% of respondents had not disclosed their serostatus to at least one person. Coworkers and lovers or main sexual partners were those most likely to know the respondents' serostatus. Reactions to disclosure were for the most part supportive. Those who had not disclosed anticipated less favorable reactions than those who had disclosed. No significant differences were observed between gay and non-gay identified respondents. The progressive social environment of Argentina that includes federal laws recognizing gay marriage may contribute to create a climate favorable for serostatus disclosure.

    2016-01-01

    Full Text Available This article presents and analyzes ethnographic data generated in Buenos Aires, the capital of Argentina, among soccer fans whose conduct is supposedly violent, and their relation to the police force. Using a theoretical framework proposed by authors working in the field of Melanesian anthropology, this text suggests that the police, with their insistence on establishing order and control, project an image of soccer fans as an unruly mob that rebels against police authority, thus leading to a neurotic escalation in the use of violence by the police. The fans, on the other hand, focus on their own supposedly heroic actions and leading roles as part of a process of individualization, and consider the police force an obstacle to the achievement of their goals, which leads them to act with even greater energy, to the point of hysteria, in their customary activities. Neurosis and hysteria are terms that are defined and used in a very specific way in this text.

    2001-01-01

    Paget's bone disease is heterogeneously distributed and several foci of high prevalence have been reported in Europe, United States, Argentina and Australia. The aim of the present work was to determine the ethnic origin of the disease in Buenos Aires using a cross sectional epidemiological study. Sample choice was based on a sampling according to grandparents' nationality. Ninety five percent of Paget patients were of European descent and 5% were non-European, while in the control group the proportion of European descendants is lower: 83% (OR: 3.7; p < 0.007; IC 95%: 1.4-9.7). Within the group of patients with Paget's disease the proportion of Italian and Russian descendants was higher than expected according to the 1914 Argentinean census. The prevalence of Paget's disease among European migrants was higher than in the control group of citizens. Regardless of environmental factors, it is likely that the migrants carried a higher risk of developing the disease

À luz dos conceitos propostos por Michael Taussig (1999 em Defacement: Public Secrecy and the Labour of the Negative o "não saber" dançar o tango por parte das mulheres se interpreta como uma ignorância sagrada que preserva a magia do tango e o lugar dos homens como únicos geradores do movimento feminino.The article explores and criticizes the relations between initiation, secret and sacred knowledge -concepts that in terms of performance theory are translated respectively as the training or performers, the relationships linking what is shown and what is not shown, and the acquisition of competence- in the context of tango lessons in Buenos Aires. Knowing how not know to dance is a central part of the performative competence acquired by women attending those classes. Under the light of concepts outlined by Michael Taussig (1999 in Defacement: Public Secrecy and the Labor of the Negative the "not knowing" how to dance tango by women is interpreted as a sacred ignorance that preserves the magic powers of the tango and the place of men as the sole creators of women’s mobility.

    Full Text Available ABSTRACT Objective To determine rates of retention, antiretroviral therapy (ART use, and viral suppression in an adult cohort from a public tertiary referral hospital in the city of Buenos Aires, Argentina. Methods HIV-positive ART-naïve patients ≥ 18 years old starting care 2011-2013 contributed data until the end of 2014. Three outcomes were assessed in 2014: retention in care, ART use, and viral suppression. Patient characteristics associated with each outcome were assessed through logistic regression. Results A total of 1 031 patients were included. By the end of 2014, 1.5% had died and 14.8% were transferred to a different center. Of the remaining 859 patients, 563 (65.5% were retained in 2014. Among those retained, 459 (81.5% were on ART in 2014. Of those 459 on ART, 270 (58.8% were virologically suppressed. Younger age was associated with lower retention (OR (odds ratio: 0.67; 95% CI (confidence interval: 0.44-0.92 for ≥ 35 vs. < 35 years, but unrelated with ART use or viral suppression. Low CD4 count at first visit was associated with ART use (OR: 35.72 for CD4 < 200, 7.13 for CD4 200-499 vs. ≥ 500, P < 0.001 and with virologic suppression (OR: 2.17 for CD4 < 200, 2.46 for CD4 200-499 vs. ≥ 500, P: 0.023. Conclusions Our hospital in Buenos Aires is still below the recommended 90-90-90 targets of the Joint United Nations Programme on HIV/AIDS (UNAIDS for ART use and viral suppression. We found a major gap in retention in care. Identifying younger age as being associated with worse retention will help in the design of targeted interventions.

    Full Text Available Objective: To show the toxicological and phylogenetic characterization of a native Microcystis aeruginosa (M. aeruginosa strain (named CAAT 2005-3 isolated from a water body of Buenos Aires province, Argentine. Methods: A M. aeruginosa strain was isolated from the drainage canal of the sewage treatment in the town of Pila, Buenos Aires province, Argentina and acclimated to laboratory conditions. The amplification of cpcBA-IGS Phcocyanin (PC, intergenic spacer and flanking regions was carried out in order to build a phylogenetic tree. An exactive/orbitrap mass spectrometer equipped with an electrospray ionization source (Thermo Fisher Scientific, Bremen, Germany was used for the LC/ESI-HRMS microcystins analysis. The number of cell/mL and [D-Leu1] Mcyst-LR production obtained as a function of time was modelled using the Gompertz equation. Results: The phylogenetic analysis showed that the sequence clustered with others M. aeruginosa sequences obtained from NCBI. The first Argentinian strain of M. aeruginosa (CAAT 2005-3 growing under culture conditions maintains the typical colonial architecture of M. aeruginosa with profuse mucilage. M. aeruginosa CAAT 2005-3 expresses a toxin variant, that was identified by LC-HRMS/Orbitrapas as [D-Leu1] microcystin-LR ([M+H]+=1 037.8 m/z. Conclusions: [D-Leu1] microcystin-LR has been also detected in M. aeruginosa samples from Canada, Brazil and Argentina. This work provides the basis for technological development and production of analytical standards of toxins present in our region.

    The number of publications in the scientific literature coming from an institution is an indicator of its scientific production. The scientific production of the hospitals of the Government of the City of Buenos Aires (GCBA) has been evaluated previously, but without discriminating how much of that production corresponded to other academic institutions settled there (University of Buenos Aires, UBA, National Council of Scientific Research and Techniques, CONICET). Our objective was to evaluate the publications included in PubMed that correspond to hospitals of the GCBA, describe their main characteristics, and discriminate the contribution of other academic institutions (UBA and CONICET). It is a cross-sectional study based on a PubMed search, using the name of each of the 34 GCBA hospitals, CONICET and UBA in the "affiliation" field. In total, 2727 publications from GCBA hospitals were identified (4.6% of Argentine publications); 73.9% in English, 78.9% in relation to humans, 37.2% in the last 5 years; 6.4% with high level of evidence (clinical trials and meta-analysis), and 28.4% including children. Compared to the national total, the GCBA publications include fewer works in English, more research in humans, more clinical trials and more research in children. Of the publications corresponding to hospitals of the GCBA, 90.4% did not share the affiliation with CONICET or with UBA. In conclusion, the GCBA hospitals generated 4.6% of the total Argentine publications in PubMed; and 90% of these was not shared with UBA or CONICET. Publications from GCBA institutions include more clinical trials and research in children.

    Full Text Available Hydatidosis is a zoonosis produced by the metacestode Echinococcus spp. The aims of this research are: to contribute to the knowledge of pediatric hydatidosis in the south-east of Buenos Aires province, to study its evolution from 1993 to 2002 at the Regional Maternity and Pediatric Hospital "Dr. Victorio Tetamanti", to determine the strains involved and to discuss the importance of the disease. The clinical records of diagnosed and/or operated patients were reviewed with regard to the hydatid disease. The strain was determined by using PCRs with Eg1 121a/122a primers. Forty-four cases were analyzed. Fifty nine point one per cent of the patients were boys. The mean age was 8 SD=3.8 years. Sixty one point four per cent had urban residence. Ultrasonography was used in 61% of the cases. The hepatic location was most frequently seen and the liver/lung ratio was 1.25. Ninety point nine per cent of patients received surgical treatment. Albendazole was used in 52% of cases. The average hospitalization time was 11 days. The Gl/G2 strain group was determined. This report is the first one of its kind in the studied region. The permanence of hydatidosis in the region depends on the natural transmission of the parasite in the absence of control and prevention measures. The health authorities should implement strategies of prevention and control in the study area.Los objetivos de este trabajo fueron: contribuir al conocimiento de la hidatidosis pediátrica en el sudeste de la provincia de Buenos Aires, estudiar su evolución desde 1993 hasta 2002, establecer la o las cepas involucradas y discutir la importancia de la enfermedad.

    Full Text Available Large quantities of disinfectants are used in hospitals, externally on human skin or to eliminate microorganisms from inanimate objects. After use, residual quantities of these products reach the wastewater, exposing the bacteria that survive in hospital wastewaters to a wide range of biocides that could act as a selective pressure for the development of resistance. Increasing attention has been directed recently to the resistance of bacteria to disinfectants. The aim of this paper was to determine the disinfectant bacterial resistance pattern of the microflora released to the urban sewer system by hospital effluents. The characterization of the waste water microflora was performed by determination of the CFU of heterotrophic bacteria, fecal indicator bacteria, Pseudomonas sp. and Staphylococcus sp., in a Buenos Aires hospital effluent. The bacterial resistance to the disinfectants more frequently used in the hospital practice, glutaraldehyde, chlorhexidine and povidone-iodine, was then evaluated. Disinfectant resistant bacterial strains were isolated and typified. Between 10³ and 10(6 chlorexidine resistant bacteria/100 mL were isolated from the samples. Bacteria resistant to other disinfectants ranged between 10³ and 10(4 /100 mL. The bacterial population resistant to desinfectants to was mainly composed by Enterobacteriaceae, Staphylococcus spp, and Bacillus spp, which are highly associated to nosocomial infections. The results obtained show that the hospital effluents are of importance in the bacterial resistance selection process, particularly in the case of disinfectants.Os hospitais utilizam uma grande quantidade de desinfetantes para eliminar microorganismos tanto da pele humana como de superfícies inanimadas.

    Full Text Available A comparative study of elements deposited on tree bark was carried out for urban and periurban areas of two of the most important cities in Argentina. The content of Fe, Mg, Al, Mn, Zn, Pb, Ba, Cr, Hg, Cu, Ni, Cd and Sb was determined by inductively coupled plasma atomic emission spectrometry (ICP-OES in Morus alba tree bark collected in the cities of Buenos Aires and Mendoza. The main air pollutants detected in the Buenos Aires urban area were Ba, Cr, Cu and Ni and indicate significative difference from the Mendoza urban and periurban areas. Significantly, higher concentrations of Zn, Ba, Cr and Cu were recorded in the periurban area of the city of Buenos Aires than in Mendoza. Bark samples were strongly influenced by dust and show Al, Fe, Mg and other element accumulations that indicate that soil particles were carried out by wind. Elements like Ba and Zn, commonly linked to traffic emissions, showed the highest concentrations in the Buenos Aires metropolitan area, possibly due to more intensive vehicular traffic. Our results indicated that intensity of vehicular traffic and not city structure is responsible for air pollution.Um estudo comparativo dos elementos depositados nas cascas das árvores foi realizado nas áreas urbanas e na periferia de duas cidades das mais importantes da Argentina.

We prospectively studied 224 consecutive female patients in order to evaluate the prevalence of vitamin D deficiency and to assess the utility of various clinical and biochemical markers in predicting the deficiency. All of them were outpatients, 30 years old or older, and were evaluated from October 2006 through March 2008. Levels of 25 OH vitamin D > 30 ng/ml were considered sufficient. Mild deficiency was considered between 20 and 30 ng/ml and severe deficiency < 20 ng/ml. The mean age was 58 ± 12.9 years; 77% were menopausal. Twenty nine percent of the patients had mild deficit and 26.8% had severe deficit of the vitamin. Severe deficit was associated with increasing age (62 vs. 56 years, p = 0.003, absence of sun exposure (25.82 ng/ml vs. 31.7 ng/ml, p < 0.005, obesity (70 vs. 61 kg, p < 0.05, absence of physical activity (27.8 ng/ml vs. 31.04 ng/ml, p = 0.0007 and slightly low levels of serum calcium (9.26 mg/dl vs. 9.51 mg/dl, p 0.01.

    Varni, Marcelo R.; Usunoff, Eduardo J.

    A three-dimensional modular model (MODFLOW) was used to simulate groundwater flow in the Azul River basin, Buenos Aires Province, Argentina, in order to assess the correctness of the conceptual model of the hydrogeological system. Simulated heads satisfactorily match observed heads in the regional water-table aquifer. Model results indicate that: (1) groundwater recharge is not uniform throughout the region but is best represented by three recharge rates, decreasing downgradient, similar to the distribution of soils and geomorphological characteristics; and (2) evapotranspiration rates are larger than previous estimates, which were made by using the Thornthwaite-Mather method. Evapotranspiration rates estimated by MODFLOW agree with results of independent studies of the region. Model results closely match historical surface-flow records, thereby suggesting that the model description of the aquifer-river relationship is correct. Résumé Un modèle modulaire tridimensionnel (MODFLOW) a été utilisé pour simuler les écoulements souterrains dans le bassin de la rivière Azul (Province de Buenos Aires, Argentine), dans le but d'évaluer la justesse du modèle conceptuel du système hydrogéologique. La piézométrie simulée s'ajuste de façon satisfaisante à celle observée pour l'ensemble de la nappe. Les résultats du modèle indiquent que: (1) la recharge de la nappe n'est pas uniforme sur toute la région, mais qu'elle est mieux approchée par trois valeurs différentes, décroissant vers l'aval-gradient, en suivant la même distribution que les sols et les caractéristiques géomorphologiques et (2) l'évapotranspiration est nettement plus importante que prévu initialement à partir de la méthode de Thornthwaite-Mather. Les valeurs d'évapotranspiration fournies par MODFLOW concordent bien avec les résultats d'autres études portant sur la région.

    The fluctuation of the water table east of La Pampa province and northwest of Buenos Aires province, Argentina, influences agricultural production in the region because it is closely related to the alternation of dry and wet periods. Sea-surface temperature (SST) anomalies have been used as predictors to forecast atmospheric variables in different regions of the world. The objective of this work is to present a simple model to forecast seasonal rainfall using SST distribution in the Pacific Ocean as a predictor. Once the relationship between precipitation and water-table fluctuations was established, a methodology for the prediction of water-table fluctuations was developed. A good agreement between observed and predicted water-table fluctuations was found when estimating water-table fluctuations in the summer and autumn seasons. Résumé. Les fluctuations de la nappe à l'est de la province de La Pampa et au nord-ouest de la province de Buenos Aires (Argentine) influence la production agricole de la région parce qu'elle est étroitement liée à l'alternance de saisons sèches et humides.

    The article explores transformations in anatomical and surgical studies within the school of medical thought in Buenos Aires in the latter half of the nineteenth century, focusing on the tension between how this knowledge should be conveyed and the changing surgical worldviews of the most visible medical groups of the 1870s. The influence of European surgical traditions is analyzed within this context, particularly the influence of the Paris tradition, which can be linked to study abroad by young Ignacio Pirovano, who would later become professor of anatomy and major surgery in Buenos Aires. The article pays special attention to changes in forms of experiments and in the new material conditions afforded through the introduction of antiseptic surgery, some types of anesthesia, and bone resection.

    Full Text Available Cemeteries with many water-filled containers, flowers, sources of human blood, and shade are favorable urban habitats for the proliferation of Aedes aegypti, a vector of yellow fever and dengue. A total of 22,956 containers was examined in the five cemeteries of the city of Buenos Aires, Argentina. The vector was found in four cemeteries that showed an average infestation level of 5.5% (617 positive out of 11,196 water-filled containers. The four cemeteries positive for Ae. aegypti showed significantly different (p<0.01 infestation levels. Vegetation cover and percentage of infestation were significantly correlated (p<0.01, but neither cemetery area nor number of available containers were significantly related to the proportion of positive vases. Our results suggest that the cemeteries of Buenos Aires represent a gradient of habitat favorableness for this vector species, some of which may act as foci for its proliferation and dispersal.

    Full Text Available El objetivo del trabajo fue presentar y analizar los datos de contaminación fecal canina y parasitaria en plazas y veredas de Buenos Aires obtenidos entre 1991 y 2006 por la Cátedra Parasitología General (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires. Se censaron las heces en varias plazas cada año en un único día entre 1991-2006. A partir del año 2000 se censaron heces en veredas circundantes. En cada plaza se seleccionaron al azar 30 heces frescas que se conservaron en formol 5% para su análisis parasitológico por el método de flotación de Willis con solución saturada de ClNa. Los 51 censos presentaron una mediana de heces de 288; un 82% de las heces se observaron en los canteros de tierra o pasto. La contaminación fecal en las plazas fue mayor en el período 2000-06 que en el anterior (p = 0.0000. La contaminación fecal de las plazas aumentó con la densidad humana en las manzanas lindantes (p = 0.0076. Las veredas mostraron un patrón inverso, ya que la contaminación fecal fue mayor en las áreas menos densamente pobladas (p = 0.0000. Se detectaron parásitos en un número variable de las heces colectadas en todas las plazas. Los géneros más frecuentes fueron Ancylostoma (20.47%, Trichuris (2.59% y Toxocara (1.70%. Nuestros resultados indican un aumento en la contaminación fecal de las plazas, posiblemente asociado con el aumento del número de perros en la ciudad combinado con las deficiencias en la implementación y el seguimiento de las medidas de control.

    Full Text Available La mirada estigmatizante de la maternidad en la adolescencia y el interés por controlar la sexualidad por parte del sector sanitario, es reciente y diferente para hombres y mujeres. Sabemos que las categorías género y edad, en tanto construcciones culturales que aluden a relaciones básicas de desigualdad -atravesadas por estructuras económico-políticas particulares-, están cargadas de significados que se dirimen en un campo social predispuesto a reforzar estereotipos naturalizantes y relaciones de dominación. El estudio se ubica en la problemática general del reconocimiento de derechos presente en los programas de salud sexual y reproductiva que tienen como destinatarias a mujeres adolescentes pobres. El recorte pone en foco el contraste entre el marco normativo y el significado que asume la maternidad para las adolescentes. Para ello, se analizan programas de salud nacionales, de la Pcia. de Buenos Aires y de la municipalidad de La Plata y discursos obtenidos en entrevistas realizadas a veinte adolescentes residentes en barrios pobres de la ciudad de La Plata. El análisis de los programas explora la incorporación del enfoque de género y la interpretación de los problemas de sexualidad/reproducción de l@s adolescentes en el marco de los derechos humanos y el de los discursos de las entrevistadas indaga su interpelación.Stigmatizing gaze of teenage motherhood and the aim to control the sexuality from the health sector, is recent and different for men and women. We know that gender and age categories, as cultural constructions that refer to basic relations of inequality-crossed by particular political-economic structures, are loaded with meanings that are settled in a social and naturalizing field predisposed to reinforce stereotypes and relations of domination. The study is placed in the general problem of aknowledgement of rights in the programs of sexual and reproductive health in adolescent girls from low environment. This frame

    Full text: The general public worries about non ionizing radiation (NIR), produced by mobile base station aren't new, mainly in big cities like Buenos Aires where the amount of antennas of wide communication services (mobile, data links, FM Broadcasting, TV and others), are so considerable. Buenos Aires City has 3 million inhabitants in a surface of 203 km 2 and has about 700 mobile base stations between macro and micro cells. When public demand arrived to local government authorities, the first logical step was to promote a big measurement campaign to do a radiation map of the city. This measurement campaign has been done for two measurement teams, one with CITEFA NIR specialists and the other with ITBA NIR specialists, during 6 months. Local NRI measurement guidelines established that has to be taken between 12 and 16 points around NRI source in a 50 m or 100 m radius, depending on the neighbourhood buildings features (buildings located in the centre of the city aren't the same as a quiet house district). The obtained measured values had to be compared with Argentinean exposure limits, which are the same that ICNIRP limits. With over 7500 measured points in the entire city with wide band instruments (200 kHz-40 GHz), we have started our analysis. This information has been used by local authorities to upgrade a radiation map that can be consulted on the local government internet site. We have compared the obtained values with some international general public exposure limits. From this comparison we found that over 90% of measured points were under general public ICNIRP cell phone frequency limits, but the surprise was that, about 80% of them were below Russian limits (6 V/m) that are the strictest of the world. According to the obtained results and to provide a conclusion we could say that, if in a big city with a very high NIR sources density, we find a majority of lower limits values, this situation will be better in a little town with few NIR sources. However

A partir del estudio de los procesos migratorios desde Bolivia y de sus cambios a lo largo de las generaciones, pretendemos postular que la escolaridad constituye parte fundamental de la experiencia de los niños y jóvenes migrantes y muy especialmente de los descendientes de inmigrantes bolivianos. Puesto que la misma afecta su formación intelectual, pero sobre todo, sus identificaciones nacionales, étnicas, de género, de clase y particularmente de edad, nos enfocaremos en comprender el rol de la escolaridad en esa etapa vital considerada como juventud. Teniendo en cuenta algunas de las representaciones mas habituales en los casos examinados, expondremos que el paso por la escuela primaria y secundaria implica un hito en las biografías de los hijos de los bolivianos y los niños y jóvenes bolivianos que se han criado en Buenos Aires y analizaremos el impacto en sus formas de identificación y sus relaciones.

    Urban territories are defined by a complex geography that includes not only the space and its features but also the styles, manners and ways of life of the social groups that take part of and compose it. In the same way, is either possible to speak about musical expressions without consider the atmosphere in which they arise and developed. This implies that a phenomenon like music, specially when it is understood as a performance, a scene and a practice, is framed in defined temporal and spatial axis. That means that music expresses an historical time and –at the same time– a specific geography. There are few cities with a so defined and recognized musical identity as Buenos Aires. The tango is the music of a shaped space, in which cultural traditions and a transforming territory are articulated. Thus, tango implies Buenos Aires and Buenos Aires implies tango. This work describes the territories of the tango throughout its history, showing its geographical migrations around the city and the consequent appropriations and resignifications experimented.

De este modo, el presente artículo se basa en un corpus documental que implica un desafío: partir de un conjunto de cartas de amor producidas por una mujer trabajadora, buscando por su intermedio adentrarnos en una relación entre dos personas y avanzar al mismo tiempo en otras direcciones. Pretendemos  ir más allá de esa dimensión y de la vida privada para estar atentas a las concepciones y experiencias en torno al noviazgo y el matrimonio.

    Full Text Available Infestation parameters and indices of mites, ticks and fleas associated with wild rodents from northeastern Buenos Aires Province, Argentina, were studied. Host species similarity was also analyzed in relation to their ectoparasites. Fifty-five rodents were captured from January 2000 to March 2001. In total, 1,022 ectoparasites were collected and three ectoparasite-host associations were new records. However, this is the first study on Craneopsylla minerva wolffhuegeli infesting parameters. Ectoparasite total mean abundance and total prevalence were higher in Holochilus brasiliensis (MA = 47.7; P = 100% and Scapteromys aquaticus (MA = 25.4; P = 95.4%, meanwhile specific richness and diversity were higher in Oligoryzomys flavescens (S = 6; H = 1.3 and Akodon azarae (S = 4; H = 1.0. On the other hand, the only individual of Calomys laucha was not parasited. S. aquaticus-H. brasiliensis, which preferred similar microhabitats, shared the same ectoparasite species (Css = 100. Whereas, A. azarae, which was mostly associated with grassland, showed the highest difference with the other hosts (Css < 0.4. Considering every ectoparasite species, H. brasiliensis showed the highest mean abundance, prevalence and preference. The results suggest that the particular characteristics of this rodent would give it better possibilities not only of being infested by ectoparasites, but also of transmitting them to its progeny.

    The Program for the Control of Intestinal Parasites and Nutrition was designed to intervene in small communities to prevent and control the effects of parasitic infections on children's health. To analyze the association between nutritional status and parasitic infection in suburban and rural children from Buenos Aires, Argentina. Nutritional status was assessed by anthropometric (weight, height, BMI, skinfolds, upper arm circumference, muscle, and fat upper arm areas) and biochemical (Hb, Ca, Mg, Zn, and Cu) indicators. Parasitological analysis were made on both serial stool and perianal swab samples. A total of 708 children aged 3-11 were measured. The biochemical analysis included 217 blood samples and the parasitological study included 284 samples. Anthropometric status was similar in both settings with low rates of underweight and stunting (children where 80% of them were hypocalcemic. Around 70% of fecal samples contained parasites. Among infected children, the most prevalent species were Blastocystis hominis and Enterobius vermicularis (~43%) followed by Giardia lamblia (~17%). Differences in parasitological status between districts were not significant. In the suburban district parasitized children were lighter, shorter, and had a lower upper arm circumference than their non-infected peers. No differences in anthropometric status were seen among infected and uninfected rural children. The results suggest an association between intestinal parasites and physical growth in suburban children. Rural children seem to be protected against the effects of parasitic infection.

    To determine tobacco point of sale advertising prevalence in Guatemala City, Guatemala and Buenos Aires, Argentina. Convenience stores (120 per city) were chosen from randomly selected blocks in low, middle and high socioeconomic neighbourhoods. To assess tobacco point of sale advertising we used a checklist developed in Canada that was translated into Spanish and validated in both countries studied. Analysis was conducted by neighbourhood and store type. All stores sold cigarettes and most had tobacco products in close proximity to confectionery. In Guatemala, 60% of stores had cigarette ads. High and middle socioeconomic status neighbourhood stores had more indoor cigarette ads, but these differences were determined by store type: gas stations and supermarkets were more prevalent in high socioeconomic status neighbourhoods and had more indoor cigarette ads. In poorer areas, however, more ads could be seen from outside the stores, more stores were located within 100 metres of schools and fewer stores had 'No smoking' or 'No sales to minors' signs. In Argentina, 80% of stores had cigarette ads and few differences were observed by neighbourhood socioeconomic status. Compared to Guatemala, 'No sales to minors' signs were more prevalent in Argentina. Tobacco point of sale advertising is highly prevalent in these two cities of Guatemala and Argentina. An advertising ban should also include this type of advertising.

    Full Text Available Sobre la base de entrevistas a treinta mujeres y treinta varones, residentes en el área metropolitana de Buenos Aires, acerca de sus experiencias de aborto, se reconstruyen trayectorias en las que el aborto constituye un hito. Se concluye que la ilegalidad no influye en la decisión de interrumpir un embarazo, sino en las condiciones diferenciales de su práctica clandestina; que las huellas del aborto marcan diferencialmente a las mujeres, en cuyo cuerpo es practicado, que a los varones, participantes secundarios del proceso, aunque las huellas sean perdurables tanto en mujeres como en varones. Asimismo, se muestra que en las mujeres pobres, al primer embarazo sigue un nacimiento y luego un aborto; que en las clases medias, al primer embarazo sigue el aborto y luego los hijos; y que la eventualidad de interrumpir el embarazo no se plantea sólo en situaciones excepcionales sino que forma parte del proceso desencadenado por la sospecha de un embarazo.

    Soil microorganisms are vital for ecosystem functioning because of the role they play in soil nutrient cycling. Agricultural practices and the intensification of land use have a negative effect on microbial activities and fungal biomass has been widely used as an indicator of soil health. The aim of this study was to analyze fungal biomass in soils from southwestern Buenos Aires province using direct fluorescent staining and to contribute to its use as an indicator of environmental changes in the ecosystem as well as to define its sensitivity to weather conditions. Soil samples were collected during two consecutive years. Soil smears were prepared and stained with two different concentrations of calcofluor, and the fungal biomass was estimated under an epifluorescence microscope. Soil fungal biomass varied between 2.23 and 26.89μg fungal C/g soil, being these values in the range expected for the studied soil type. The fungal biomass was positively related to temperature and precipitations. The methodology used was reliable, standardized and sensitive to weather conditions. The results of this study contribute information to evaluate fungal biomass in different soil types and support its use as an indicator of soil health for analyzing the impact of different agricultural practices.

    Full Text Available Research on creativity has acquired major development due to its relevance concerning teaching in college. Its assessment is generally conducted by means of verbal and graphic measures. A short scale to measure verbal creativity (CREA in college students from Buenos Aires is currently available. However, right now there are no similar scales designed to assess graphic creativity. In view of that, this study will analyse psychometric features of the ECG scale locally known as Evaluación de la Creatividad Gráfica – Graphic Creativity Assessment, to be employed in the academic milieu in order to provide a complementary measure of verbal creativity. Face and construct validity evidences (converging validity analysis and confirmatory factor analysis were examined as well as reliability, taking into account internal consistency aspects, inter-rater and test-retest stability. The resulting scale showed adequate technical features. The original version, supported by De la Torre’s model, was composed by 12 indicators. This study’s findings maintained 9 of them but, considering new analyses, only 4 of the original ones were retained. This 4-indicator model obtained a better fit to empirical data and good indexes of correlation with a verbal creativity measure, as well as good reliability indicators (internal consistency, inter-rater and test-retest. Findings are discussed taking into account theoretical basis.

    Understanding influences on women's preferred delivery mode is vital for planning interventions to reduce cesarean rates and for ensuring that women receive correct information. Our objectives were to: determine if sources of information influencing a pregnant woman's preferred delivery mode and knowledge of cesarean indications differ by sociodemographic characteristics; to conduct a factor analysis of items related to information sources influencing this preference; and to determine if knowledge differs by information sources influencing this preference or their underlying latent constructs. Data from a prospective cohort study conducted in Buenos Aires was analyzed. Healthy nulliparous women aged 18-35, at >32 weeks of gestation and with live, singleton pregnancies participated. The primary research questions were evaluated using Chi-square tests, factor analysis, logistic regression, and generalized estimating equations. A total of 382 women participated in the study. Women of lower socioeconomic status were more influenced by people, magazines and TV/movies in their mode of delivery preferences, and had poorer knowledge of cesarean indications. Sources of influence for preferred delivery mode and factors derived in factor analysis were not associated with knowledge level when considered individually or together, or when adjusted for sociodemographic characteristics, or when accounting for clustering by the hospital sector (public or private). Higher socioeconomic status is associated with being less influenced by people and with better knowledge of indications for cesarean delivery. Knowledge of cesarean indications was not associated with the source of information about mode of delivery preferences. © 2017 Wiley Periodicals, Inc.

Esta institución fue conformada en la ciudad de Buenos Aires, en 1943, por un grupo de mujeres de sectores sociales altos y medios. En un contexto de incertidumbre biomédica la entidad movilizó recursos materiales y simbólicos para dar respuesta al problema de la rehabilitación de las afecciones físicas permanentes que la enfermedad provocaba en sus víctimas. Utilizando como fuente las memorias institucionales de la organización, se muestra cómo médicos y filántropas constituyeron una alianza médico-social y desarrollaron el interés fundamental de practicar una modalidad de tratamiento –en un contexto donde todo estaba por hacerse- sostenidos en un andamiaje que amalgamaba ideas cristianas con innovaciones de la medicina y la rehabilitación.

    Full Text Available This study aimed to identify the individual and environmental determinants of nonadherence to tuberculosis (TB treatment in selected districts in the Buenos Aires Metropolitan Area, in Argentina. We conducted a cross-sectional study using a hierarchical model. Using primary and secondary data, logistic regression was performed to analyze two types of determinants. The likelihood of nonadherence to treatment was greatest among male patients. The following factors led to a greater likelihood of nonadherence to treatment: patients living in a home without running water; head of household without medical insurance; need to use more than one means of transport to reach the health center; place of residence in an area with a high proportion of households connected to the natural gas network; place of residence in an area where a large proportion of families fall below the minimum threshold of subsistence capacity; place of residence in an area where a high proportion of households do not have flushing toilets and basic sanitation. Our results show that social and economic factors – related to both individual and environmental characteristics – influence adherence to TB treatment.

Se identificaron rodales de Eucalyptus viminalis Labill. cuyas edades oscilaron entre 4 y 14 años. Se apearon 21 árboles con diámetros entre 9,2 y 32,5 cm. Se desarrollaron regresiones simples y múltiples y se estimó el volumen, la biomasa en ramas, hojas y fuste. Las ecuaciones de volumen de mejor comportamiento son basadas en modelos lineales en su forma normal, y el modelo más adecuado fue el que incorporó al d2 (R2 = 0,92. Para la estimación de la biomasa en hojas, ramas, copa y fuste se recomienda los modelos ln-ln que consideran el d y h o solo el d. El componente de la biomasa en hojas presentó una estimación más débil. La distribución de la biomasa en los individuos sigue el patrón de desarrollo que se encuentra en la bibliografía. La proporción de la biomasa en la copa disminuye con la edad, contrariamente a lo sucedido con el fuste.

    2016-07-01

    In 1887, only five years after Jean-Martin Charcot was awarded the Head of Neurology at "La Salpetrière" in Paris, José María Ramos Mejía became the first professor of Neurology in South America, at the School of Medicine of the University of Buenos Aires. Ramos Mejía convoked three assistants, the neuropathologist Christofredo Jakob, the clinician José A. Esteves and José Ingenieros. Hence it followed that Neurology in Argentina took a stand based on a clinical neurology-neuropathology approach (1941-1987) followed by a clinical-semiological attitude, finally inserting itself within the modern times (1987-present) by creating subspecialties. Throughout its history, Argentina has made remarkable contributions to Neurology, such as the diagnosis and pathogenesis of the nervous system involvement occurring in some regional endemic disorders -for instance, Chagas' disease-, the clinical approach to the diagnosis of dementias, and the pathogenesis of extrapyramidal illnesses and other primary degenerative diseases of the central nervous system, mainly amyotrophic lateral sclerosis. On the other hand, in recent years globalization allowed neurologists to participate in international cooperative projects, favoring a swifter development in the practice of this discipline.

    Full Text Available In this paper, the sale of medicinal plants was described in the urban city of Buenos Aires, Argentina. Semi-structured interviews were conducted with pharmacists and herb store owners about different characteristics of retail. Likewise, different types of retailers were compared, and the phytomedicine degree of acceptance was consulted. The percentage of customers who buy medicinal plants in herb stores is higher than in pharmacies. The five most demanded species were: "malva" (Malva sp., 18%; "manzanilla" (Matricaria recutita, 13%; "tilo" (Tiliasp., 12%; "cuasia" (Picrasma crenata, 8%; and "boldo" (Peumus boldus, 7%. In like manner, the most demanded mixes of species were those that had slimming properties, 21%; digestive, 17%; sedative and diuretic, 13%. Of the 32 most frequently requested species, only 13 are native. Phytomedicines were widely accepted in the different kinds of retail stores. It was also emphasized that, contrary to the usual assumption, the choice to consume plants is cultural rather than economic. Due to the acceptance observed in the use of phytomedicines, it must be emphasized the potential that Argentina possesses for the development of this industry.

    Full Text Available En este artículo propongo una exploración antropológica sobre la crianza y la educación infantil en contextos de desigualdad social. El interés es discutir una serie de supuestos que suelen limitar las prácticas educativas de los sectores subalternos a "pautas tradicionales" y "privativas del mundo familiar". Sin embargo, en las iniciativas domésticas sobre la crianza y el cuidado infantil que analizo, intervienen actores esperables para ello y también un conjunto de sujetos e instituciones no formalizadas pero que se tornan relevantes en la cotidianeidad de los territorios de pertenencia de los niños y niñas. Para el análisis me basaré en las entrevistas y en los registros de tipo etnográfico que llevé a cabo en asentamientos ubicados en la zona norte del Gran Buenos Aires, Argentina.

    Full Text Available El presente artículo analiza la extensión universitaria como estrategia de legitimación de las universidades, atendiendo a las convergencias y divergencias en un presente atravesado por una fuerte diversificación institucional en el campo universitario. Se centra en el análisis institucional de la extensión a partir del estudio en/de 4 universidades nacionales y privadas ubicadas en la Ciudad de Buenos Aires. Se analizan la presentación institucional, la significación y organización de la extensión, y la actualización de su historia y el contexto y público al que apelan. Se describen las metáforas espaciales con que se presenta la extensión y los distintos sentidos sobre la educación universitaria asociados a ella. Se concluye que la extensión universitaria cobra sentido en función del mecanismo de inclusión/exclusión, el carácter selectivo de la universidad. En la relación con actores extrauniversitarios, la legitimidad se resuelve en relaciones con sectores populares, empresariales, ong y el Estado.

    Oral Squamous Cell Carcinoma has a low survival rate, 34 to 66% five-year survival after initial diagnosis, due to late diagnosis. The aim of the present study was to examine the clinical features and evolution of oral cancer in the University of Buenos Aires. 274 patients with primary oral carcinoma, over the 1992-2000 period were included in the study. The survival rate of this population was 80% at 12 months, 60% at 24 months, 46% at 36 months, 40% at 48 months, and 39% at 60 months (5 years). The tumor localizations with worse prognosis were floor of mouth and tongue, with survival rates of 19% and 27% respectively. Sixty-five percent of the oral carcinomas evaluated were diagnosed at advanced stages (III and IV). The patients under study exhibited the lowest survival rate described for oral cancer (34% five-year survival after initial diagnosis). The population included in this study can be considered representative of the Argentine population. This bad prognosis would be mainly due to the large number of oral cancer cases that were diagnosed at advanced stages.

    In Argentina, unsafe abortions are the primary cause of maternal mortality, accounting for 32% of maternal deaths. During reform of the National Constitution in 1994, the women's movement effectively resisted the reactionary government/church position on abortion. Health professionals, including obstetrician-gynaecologists, played conflicting roles in this debate. This article presents results from a study carried out in 1998-1999 of the views of 467 obstetrician-gynaecologists from public hospitals in Buenos Aires and its Metropolitan Area, focus group discussions with 60 of them, and interviews with heads of department from 36 of the hospitals. The great majority believed abortion was a serious public health issue; that physicians should provide abortions which are not illegal; that abortion should not be penalized to save the woman's life, or in cases of rape or fetal malformations; and that women having illegal abortions and abortion providers should not be imprisoned. Some 40% thought abortion should not be penalized if it is a woman's autonomous decision. Those who were better disposed towards the de-penalization of abortion cited a combination of public health reasons and the need for social equity. The women's health and rights movement should do advocacy work with this professional community on women's needs and rights, given the prominent role they play in reproductive health care provision and in the public sphere.

Como manifestacion clinica inicial el 82% de ellos mostro convulsiones y el 73% cefaleas. Ambas alteraciones podían estar combinadas en el mismo paciente o presentarse en forma independiente. La tomografia computada de cerebro evidencio calcificaciones y quistes en 5 enfermos, solo calcificaciones en 3, hidrocefalia en 2 y un unico quiste en 1. En 7 casos se efectuo ELISA en el LCR, de ellos 6 resultaron positivos. El tratamiento medico se hizo en base a la administración de praziquantel o albendazol con buena evolución de los pacientes en todos los casos. El tratamiento quirúrgico fue indicado solo en el caso en que una lesion actuase como masa ocupante con aumento de la presión endocraneana (1 caso o produjera obstruccion de la circulacon del LCR llevando a una hidrocefalia (2 casos. El estudio presente pretende alertar sobre la posibilidad que nuevas regiones, como la Ciudad de Buenos Aires, puedan ingresar dentro del area endemica latinoamericana a consecuencia de los movimientos migratorios internos y externos y el asentamiento de portadores de la parasitosis en el perimetro urbano.

    The primary objective of this study was to estimate the prevalence of this disease in women of childbearing age and children treated at health centres in underserviced areas of the city of Buenos Aires. Demographic and Chagas disease status data were collected. Samples for Chagas disease serology were obtained on filter paper and the reactive results were confirmed with conventional samples. A total of 1,786 subjects were screened and 73 positive screening results were obtained: 17 were from children and 56 were from women. The Trypanosoma cruzi infection risk was greater in those individuals who had relatives with Chagas disease, who remember seeing kissing bugs, who were of Bolivian nationality or were born in the Argentine province of Santiago del Estero. The overall prevalence of Chagas disease was 4.08%. Due to migration, Chagas disease is currently predominantly urban. The observed prevalence requires health programme activities that are aimed at urban children and their mothers. Most children were infected congenitally, which reinforces the need for Chagas disease screening of all pregnant women and their babies in Argentina. The active search for new cases is important because the appropriate treatment in children has a high cure rate.

    Full Text Available Conceituar o  terrorismo é uma questão complicada. Alguns teóricos o definem por seus efeitos, outros por suas causas. No presente artigo, o conceito de terrorismo é baseado na aproximação dialética entre causas e efeitos. Dessa maneira, o caso World Trade Center apresenta-se confrontado com os ataques ocorridos em Buenos Aires em 1992 e 1994. Enquanto este foi apresentado como um ataque à comunidade judaica, aquele foi apresentado pela mídia como uma ofensa à Humanidade. Naturalmente, Argentina e Estados Unidos mantem políticas diversas para lidar com o terrorismo. Em perspectiva, se pode especular que o terrorismo parece ser uma assunto profundamente  relacionado à mobilidade e ao monopólio da alienação simbólica. Isso suscita uma questão muito interessante,  que a literatura especializada  ainda não respondeu: por que o 11 de Setembro é mais importante do que outros eventos similares? Nesse contexto, a reflexão proposta visa não só desvendar  o quebra-cabeças  em torno do terrorismo, mas também discorrer de forma convincente sobre as razões pelas quais o turismo é economicamente pré-condição para o advento do terrorismo e vice versa.  

  15. Eugenesia en Buenos Aires: discursos, prácticas, historiografía

    Diego Armus

    Full Text Available Resumen En la década de 1990, algunos estudios subrayaron la dominante presencia de la eugenesia positiva en la Argentina moderna. Enfatizaban en el lugar marginal que en los discursos eugenésicos tuvieron los violentos métodos de selección. En los últimos años esta perspectiva ha sido revisada, señalando la viscosidad conceptual de la eugenesia y la presencia de discursos eugenésicos negativos. Este artículo comenta estos avatares historiográficos y también se detiene en las narrativas que estas perspectivas han articulado respecto del problema de la esterilización y regulación del matrimonio de quienes padecían tuberculosis en Buenos Aires durante la primera mitad del siglo XX. Con ese ejemplo se intenta remarcar la necesidad de tensionar discursos y prácticas en cualquier empeño por entender el pasado.

    Full Text Available Este artículo está basado en una investigación cualitativa cuyo objetivo fue explorar las opiniones de varones de 25 a 39 años de estratos socioeconómicos medios y populares, residentes en el Área Metropolitana de la Ciudad de Buenos Aires, Argentina (n: 30 acerca de la despenalización del aborto y sus representaciones sociales sobre el mismo. Los hallazgos han corroborado resultados previos y han aportado nuevos conocimientos. Se confirmó la ambivalencia de los discursos sobre el aborto, ya que primaron una opinión favorable a su despenalización, y una representación social fundada en un eje moral opuesto al aborto. De los resultados se desprende la necesidad de investigar los puntos de vista de los varones sobre los derechos de mujeres y varones, y de profundizar los sondeos de opinión a través de estudios cualitativos en los que se indaguen sus representaciones sociales en el campo de los derechos sexuales y reproductivos.

    The intrauterine device (IUD) is a long-acting reversible contraceptive method that is safe for a wide range of women, including adolescents and nulliparous women. Globally, it is often underutilised due to misperceptions among patients. Examination of characteristics associated with IUD discontinuation including adverse effects and IUD expulsion can inform provider practices to improve contraception success and patient satisfaction with this method. We studied IUD performance at a public family planning clinic in Buenos Aires, Argentina, serving a predominantly immigrant, low-income population. We conducted a retrospective evaluation of 1047 IUD insertions between 2002 and 2007 with 5 years of follow-up data. We performed bivariate and survival analysis to examine characteristics associated with IUD discontinuation: adverse outcomes including pain, bleeding, and IUD expulsion, and time to removal. Of 1047 patients, only 188 (18%) had their IUD removed within 5 years. The main causes of IUD discontinuation were involuntary (38%) reasons such as an IUD expulsion and personal choice (34%) such as desiring pregnancy. Findings suggest overall good long-term performance with IUD insertion, with minimal complaints or adverse outcomes. These findings may help to support providers serving similar populations in promoting this method. Published by the BMJ Publishing Group Limited.

    Leptospirosis is an infectious disease of wide global distribution, which is endemic in Argentina. The objective of this study was to obtain the genetic profiles of Leptospira spp. strains isolated from clinical cases of dogs in the province of Buenos Aires by the multiple-locus variable-number tandem repeat analysis (MLVA). Eight isolated canine strains were genotyped by MLVA, obtaining the identical profile of Leptospira interrogans serovar Canicola Hond Utrecht IV in the strains named Dogy and Mayo. The strains named Bel, Sarmiento, La Plata 4581 and La Plata 5478 were identical to the profile of the genotype of L. interrogans serovar Portlandvere MY 1039.The strain named Avellaneda was identical to the genotype profile of L. interrogans serovar Icterohaemorrhagiae RGA and the strain named SB had the same profile as the L. interrogans serovar Pomona Baires genotype and was similar to the profile of serovar Pomona Pomona genotype. It would be useful to include a larger number of isolates from different dog populations in various provinces of Argentina and to characterize the genetic profiles of the strains circulating in the country. The information obtained will be useful for the control of leptospirosis in the dog population. Copyright © 2014 Asociación Argentina de Microbiología. Publicado por Elsevier España.

    The geomorphological evolution of a sand-dune barrier in Buenos Aires, Argentina, is analyzed as a factor regulating the fresh groundwater reserves available. The impact of geomorphological evolution and the consequences for the social and economic development of two coastal areas are assessed. This is one of the most important tourist destinations in the country; for study purposes, it was divided into a northern sector and a southern sector. In the southern sector, the exploitable groundwater is associated with the Holocene and upper Pleistocene geomorphological evolution, which generated three interrelated aquifer units, constituting a system whose useful thickness reaches at least 45 m. In contrast, the northern sector is restricted to two Holocene aquifer units, whose total thickness is on the order of 12 m. The morphological characteristics and the occurrence of the largest fresh groundwater reserves in the southern sector are indicators of better conditions for economic growth, which is mainly reflected on the expansion of real estate ventures. The relationships of transmissivity vs area of real estate ventures (Arev), and total water consumption vs Arev, are indicators for the sustainable management of the water resources. The approach chosen may be used by decision makers in other regions to assess the feasibility of future tourism projects on the basis of the availability of water resources associated with geomorphological features.

    Using the approaches of history of the present, this article recovers the discussions surrounding the 12th International Conference on Cancer carried out in Buenos Aires in 1978, in reaction to which Georges Périès organized a "counter-conference" in Paris. In order to understand this discussion, the political situation of the time is described, as is the state of human rights at the time in Argentina, the role of the media - in particular the newspapers La Nación and Clarín and the magazine Gente - and the institutional position adopted by the National Academy of Medicine, as expressed in a letter sent to the presidents of the primary scientific societies of the world. The letter is reprinted in this text as a documentary source, taken from Memoria: Año 1978 (Presidencia de Dr. José E. Rivarola) [Acta: Year 1978 (Presidency of Dr. José E. Rivarola)]. The framework of the discussion makes reference to science's social policy versus science's supposed neutrality and the role of scientific societies.

Interesa interrogarnos si los vecinos de clase media o alta que se “acuartelan” tras muros o rejas son los únicos que experimentan temor en nuestras ciudades signadas por la desigualdad o, por el contrario, es posible discernir los temores de los sectores populares, en franca sintonía con las políticas resueltamente contradictorias que implementa el poder local, que he de denominar esquizopolíticas. Por otra parte, me interesa analizar de qué modo las villas, asentamientos u ocupaciones ilegales son percibidos por el resto de la sociedad como usinas donde en apariencia se “generan” sujetos que provocan miedo, incertidumbre y desorden. Veremos también cómo la cultura y la naturaleza son construidas veladamente, desde ciertos proyectos, como antítesis del miedo.

    Several species of microsporidia and coccidia are protozoa parasites responsible for cholan-giopathy disease in patients infected with human immunodeficiency virus (HIV). The goals of this work were to identift opportunistic protozoa by molecular methods and describe the clinical manifestations at the gastrointestinal tract and the biliary system in patients with AIDS-associated cholangiopathy from Buenos Aires, Argentina. This study included 11 adult HIV-infected individuals with diagnosis ofAIDS- associated cholangiopathy. An upper gastrointestinal endoscopy with biopsy specimen collection and a stool analysis for parasites were performed on each patient. The ultrasound analysis revealed bile ducts compromise. An endoscopic retrograde cholangiopancreatography and a magnetic resonance cholangiography were carried out. The identification to the species level was performed on biopsy specimens by molecular methods. Microorganisms were identified in 10 cases. The diagnosis in patients with sclerosing cholangitis was cryptosporidiosis in 3 cases, cystoisosporosis in 1 and microsporidiosis in 1. In patients with sclerosing cholangitis and papillary stenosis the diagnosis was microsporidiosis in 2 cases, cryptosporidiosis in 2 and cryptosporidiosis associated with microsporidiosis in 1. In 3 cases with cryptosporidiosis the species was Cryptosporidium hominis, 1 of them was associated with Enterocytozoon bieneusi, and the other 2 were coinfected with Cryptosporidium parvum. In the 4 cases with microsporidiosis the species was Enterocytozoon bieneusi. These results suggest that molecular methods may be useful tools to identify emerging protozoa in patients with AIDS-associated cholangiopathy.

    Full Text Available Hospital wastewater (HWW constitutes a potential risk to the ecosystems and human health due to the presence of toxic and genotoxic chemical compounds. In the present work we investigated toxicity and genotoxicity of wastewaters from the public hospital of Buenos Aires (Argentina. The effluent from the sewage treatment plant (STP serving around 10 million inhabitants was also evaluated. The study was carried out between April and September 2012. Toxicity and genotoxicity assessment was performed using the green algae Pseudokirchneriella subcapitata and the Allium cepa test, respectively. Toxicity assay showed that 55% of the samples were toxic to the algae (%I of growth between 23.9 and 54.8. The A. cepa test showed that 40% of the samples were genotoxic. The analysis of chromosome aberrations (CA and micronucleus (MN showed no significant differences between days and significant differences between months. The sample from the STP was not genotoxic to A. cepa but toxic to the algae (%I = 41%, showing that sewage treatment was not totally effective. This study highlights the need for environmental control programs and the establishment of advanced and effective effluent treatment plants in the hospitals, which are merely dumping the wastewaters in the municipal sewerage system.

    Full Text Available During 1995, 16 species of arthropods and 2 species of filarioids, totaling 1 287 specimens were collected from 64 wild rodents captured in the Hudson Natural Reserve, Buenos Aires, Argentina. Infestation parameters and indexes were analyzed. Host specific richness was S = 6, diversity H = 1.48, and relative density RDI = 40%. High values of parasite species richness and diversity were found on Oligoryzomys delticola (S = 9; H = 1.40, Oxymycterus rufus (S = 9; H = 1.37, and Oligoryzomys flavescens (S = 9; H = 1.28, followed by Scapteromys aquaticus (S = 6; H = 0.17, and Akodon azarae (S = 4; H = 1.20. Deltamys kempi was infested only by Androlaelaps rotundus. O. delticola and O. flavescens showed the highest similarity index (O = 74.19%, followed by O. flavescens with S. aquaticus, as a result of historical processes and shared microhabitats. Considering arthropods-filarioids associations, significant affinity was observed in Litomosoides bonaerensis with Hoplopleura travassosi, Laelaps paulistanensis, and Gigantolaelaps wolffsohni.

    This paper supplements analyses of Argentine transmission expansions at the federal level by looking at experience in Buenos Aires province. A Regional Electricity Forum of distribution companies has drawn up and begun to implement a 10-year transmission expansion plan. Contrary to previous fears, getting agreement between the members on investment and cost sharing has not been unduly problematic. More challenging was getting approval of the provincial government on funding. Deferring tariff reductions and using the revenues for investment facilitated the process, and now some innovative financing arrangements are underway. Again contrary to some previous suggestions, the controversial Area of Influence method was extended rather than replaced. This overcame concerns about free-riding. Progress and investment have been severely curtailed by the economic crisis in 2001 and subsequent federal government policy. The arrangements nonetheless appear to be working well, and to be conducive to more efficient transmission expansion. This confirms that it is practicable and advantageous to allow users rather than the transmission company or the regulator to propose and determine transmission investment, even in a meshed rather than radial system. An appropriate regulatory framework is needed to approve that part of the total budget to be paid by distribution business consumers, but this does not require the regulator to lead or monitor the detail of the process.

    Information on disease presence can be of use to natural resource managers, especially in areas supporting threatened and endangered species that occur coincidentally with species that are suspected vectors for disease. Ad hoc reports may be of limited utility (Muths et al. 2009), but a general sense of pathogen presence (or absence) can inform management directed at T&E species, especially in regions where disease is suspected to have caused population declines (Bradley et al. 2002). The Chiricahua Leopard Frog (Lithobates chiricahuensis), a species susceptible to infection by the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd) (Bradley et al. 2002), and the non-native, invasive American Bullfrog (L. catesbeianus), a suspected vector for chytridiomycosis (Schloegel et al. 2012, Gervasi et al. 2013), both occur at Buenos Aires National Wildlife Refuge (BANWR) and surrounding lands in southern Arizona. Efforts to eradicate the bullfrog from BANWR began in 1997 (Suhre, 2010). Eradication from the southern portion of BANWR was successful by 2008 but the bullfrog remains present at the Arivaca Cienega and in areas immediately adjacent to the refuge (Fig. 1). Curtailing the re-invasion of the bullfrog into BANWR will require vigilance as to ensure the health of Chiricahua Leopard Frog populations.

    To analyse the methods of reasoning with regard to patients' experiences of living with psychogenic nonepileptic seizures (PNES) in Buenos Aires, Argentina. A qualitative approach using semi-structured interviews was used to gain an in-depth and contextual understanding of the perspectives of five patients with PNES. Data collection and analysis were followed by an inductive and interpretive approach informed by the principles of thematic analysis. Explanatory models and prototypes were identified from the patients' narratives. Four patients related their suffering regarding psychosocial causes -family conflicts, sexual harassment, and life changes, among others-. Hereditary and organic hypotheses appeared to be unspecific. Folk explanations were common to all participants (magic, witchcraft, energetic causes). Four patients used the term epilepsy as an illness prototype, focusing on seizures and the use of antiepileptic drugs. Three of them also compared their illness to other people's "attacks" (heart attacks, panic attacks, nervous breakdown). Only one of them referred to someone who was suspected of having epilepsy. Patients' psychosocial explanatory models are different from the results of previous studies because these studies indicate that most patients support somatic explanations. Patients also use folk explanations related to traditional medicine, which highlights the interpersonal aspects of the disease. Doctor-patient communication is essential for a correct understanding of PNES, resulting in better outcomes. It could also help to reduce the cultural distance between professionals and patients, leading to narrowing inequalities present in multicultural healthcare services.

    The study area is in the south end of Buenos Aires outskirts. The population is of 42000 inhabitants, from which 69% is supplied of water by means of domiciliary wells. The water for human consumption is located in Pampeano and Puelches aquifers, which form a series of semi-free aquifers of the multi-layer type that are hydraulically connected. The aim of this work was to analyze the nitrate content in the groundwater (Pampeano and Puelches aquifers) and to evaluate the pollution type. The percentage of wells that overcome the range 40-50 mg/l of nitrates was 34% for Pampeano aquifer and 36% for Puelches aquifer. Results obtained for the Pampeano aquifer suggest that the pollution would be produced by a pseudo diffuse process associated to septic wells. Meanwhile, in the Puelches aquifer, the same process of pseudo diffuse pollution would be produced but in this case its origin would be caused by the water migration with nitrates from the Pampeano aquifer. Results mentioned in this work make evident the deterioration process of groundwater, where the pollution would be related to the anthropic activity, coming principally from the urban zone [es

    A stepwise logistic regression (LR) model was generated to evaluate the association between contamination of groundwater by nitrates with several risk factors such as soil types, farm facilities and practises, and well characteristics. The odds ratio was calculated to estimate the degree of impact that the associated variables had on the risk of contamination in a semiconfined multilayer aquifer underlying rural areas of Buenos Aires, Argentina. Duplicate farm groundwater samples ( n = 160) were taken and nitrate was analyzed. Data, involving various farm factors, was gathered via two questionnaires concerning farm’s general and productive aspects, and well characteristics. Statistical tests were run between nitrates and each variable present in the survey. A 96.25% of the samples presented detectable nitrate levels, 40.91% of which had more than 45 ppm nitrates. The final LR model involved five of the variables under study: well age, soil permeability, depth of water table, location, and distance from well to contamination sources. Cross validation proved to be a good estimator of nitrate water contamination. Suspicions about how these characteristics influence groundwater contamination by nitrates were confirmed, and as these five factors represent a higher risk for this type of aquifer, their proper management may contribute to a better resource protection.

    Eleven patients with diagnosis of possible neurocistycercosis were studied in our Department since 1986. All of them were adults. Eight were Bolivian citizens. The commonest neurological clinical manifestation were seizures and/or headache. Brain CT scans showed cystic lesions and calcifications in 5 patients, only calcifications in 3, enlarged ventricles in 2 and an isolated frontal cystic lesion in 1. Six out of 7 patients who were submitted to spinal fluid ELISA test showed positive response for cysticercosis. Patients were put on praziquantel (50 mg/Kg/d) or albendazol (15 mg/Kg/d) with good outcome for all them. Surgery was carried on for treatment of enlarged ventricles (2 patients) and for a like-expansive lesion (1 patient). The aim of this work is to underscore the fact that in Buenos Aires city, which previously was not within the endemic latin american area for cysticercosis, is now possible to find patients with the neurological manifestations of this parasitosis, most probably due to migration of people coming from the north provinces or from countries situated at its border where the disease is endemic.

    Objectives To determine tobacco point of sale advertising prevalence in Guatemala City, Guatemala and Buenos Aires, Argentina. Methods Convenience stores (120 per city) were chosen from randomly selected blocks in low, middle and high socioeconomic neighbourhoods. To assess tobacco point of sale advertising we used a checklist developed in Canada that was translated into Spanish and validated in both countries studied. Analysis was conducted by neighbourhood and store type. Results All stores sold cigarettes and most had tobacco products in close proximity to confectionery. In Guatemala, 60% of stores had cigarette ads. High and middle socioeconomic status neighbourhood stores had more indoor cigarette ads, but these differences were determined by store type: gas stations and supermarkets were more prevalent in high socioeconomic status neighbourhoods and had more indoor cigarette ads. In poorer areas, however, more ads could be seen from outside the stores, more stores were located within 100 metres of schools and fewer stores had ‘No smoking’ or ‘No sales to minors’ signs. In Argentina, 80% of stores had cigarette ads and few differences were observed by neighbourhood socioeconomic status. Compared to Guatemala, ‘No sales to minors’ signs were more prevalent in Argentina. Conclusions Tobacco point of sale advertising is highly prevalent in these two cities of Guatemala and Argentina. An advertising ban should also include this type of advertising. PMID:20530136

    The goal of this article is to explore, through bodily codes, the knowledge, possibilities and limits that a group of Peruvian immigrants find in Buenos Aires in the 1990s. Immigrants’ body language in relation to other social, national and cultural groups allows us to show how different ways of presenting Peruvian and Argentine identity are expressed in acting, talking, gesturing, walking, dressing or moving. An improvisation drama workshop, an etiquette workshop and interactions of Peruvian street vendors are privileged settings to study migratory processes using complex body performances as a heuristic tool.

    Previous studies in special schools have shown a high prevalence of epilepsy, which is strongly associated with cerebral palsy and severe mental retardation. The conditions regulating school placement have also been described in those studies. In the City of Buenos Aires, information is known only for mainstream schools. To determine the prevalence and characteristics of epilepsy in special schools and to compare results with common primary education settings. A cross-sectional study was carried out in special schools in the City of Buenos Aires, by adopting the same definitions, diagnostic criteria and questionnaire as those used in a previous study in the common primary school population. Responses from 1,682 children, aged 6-16 years, residing in the City of Buenos Aires, with mental retardation, visual or hearing impairment, psychiatric disorders and motor disabilities were analyzed. A total of 121 children with epilepsy were detected. Lifetime prevalence was 71.9 per thousand and active prevalence was 64.8 per thousand (22-25 times greater than rates in mainstream schools). Prevalence was highest in girls and generalized seizures prevailed over other seizure types. Ninety-two percent of cases received antiepileptic drugs, 57.9% as a single drug treatment and 85.1% in adequate doses. Only 56% of the children with a diagnosis of epilepsy proved to be true-positive cases, and almost 40% received antiepileptic drugs for nonepileptic disorders. Malformations/degenerative disease were the most common etiology. Special schools contain clusters of children with epilepsy as a comorbid condition. False high frequency is due to misdiagnoses and unnecessary treatments. These schools are an important target for educational interventions. 2008 S. Karger AG, Basel.

At first the privileged groups of the city collected the tradition of Ius Commune to qualify certain groups of the lower classes as miserables worthy of charity. But in the last decades of the colonial rule, there was a different reception of new speeches among royal authorities, council elite and intellectuals, and appeared the suspicion that among the dispossessed there was fertile ground for laziness and reluctance to work. So new projects and courses of action took place.

    Concentrations of 21 Pb and 137 Cs in sediment samples collected from two cores at a drainage channel to the La Plata river estuary in Buenos Aires, Argentina, were measured using ultralow-background detection systems. The 21 Pb data were used to determine the rate of sediment accumulation of the sites. These results were correlated with some heavy metal (chromium and lead) concentrations of the samples in an attempt to characterize the historical input of contaminants due to the industrial development, which has taken place in this area over the last century. The 137 Cs measurements demonstrate that cesium dating is not adequate in regions of the southern hemisphere

    Groundwater pollution is a major concern in peri-urban environments. Thus, water quality is being investigated at several domestic wells in Brandsen, 70 km south of Buenos Aires, Argentina. To present, about 20 water sources were sampled in orchards and small farms of the area. There is limited data about the wells construction, although collected information suggests that groundwater is derived from the superficial sandy loams of the Pampean Aquifer. Samples were analysed for major inorganic elements using ion chromatography and ICP-MS. Titration was used to estimate alkalinity. Physical characteristics (EC, pH, temperature) were measured on site. Results show that groundwater pH ranges from 6.5 to 7.8, with a specific conductance of 180 to 255 mS/m. A peak of 360 mS/m in one horticultural parcel is associated to local NO3- concentrations up to 140 mg/L. This value exceeds the maximum recommendations set by the WHO (50 mg/L). Considering that fertilizer inputs in that property are negligible, the high levels of NO3- might be attributed to effluents from a neighbour septic tank. An increase in NO3- (>150mg/L) was also detected in two conventional farms. This increase correlates to elevated SO42- concentrations (>300 mg/L) suggesting thus, fertilizers percolation into the saturated zone. The leaching of these fluids might be exacerbated by irrigation during new planting, and accumulations of fertilizer-solids in the root zones from previous seasons. Chloride concentrations average ~90 mg/L and would not pose a threat to health at the moment. Its main origin would be related to connate waters in the loam matrix, although some anthropogenic inputs might occur in the previously described farms. In general, the rest of the analysed elements fall within acceptable levels for drinking purposes as well. Nevertheless, further work is still necessary to better define the fate of the potential harmful elements and assess seasonal variations in water quality.

    The radioisotopes techniques have notably contributed to the advancement of knowledge in medicine and biomedicine during the last 60 years. The School of Pharmacy and Biochemistry of the University of Buenos Aires, Argentina, offers different Courses on methodology of radioisotopes in which the specialized knowledge on radioprotection is adapted to the following different groups: 1) A course for biochemistry students; 2) A course for physicians; 3) A course for graduates in biochemistry, biology, chemistry or other disciplines related to the health; 4) An up-dating course for licensed professionals; 5) A course for nuclear medicine technicians; and finally: 6) A course for Pharmacy students. The main objective of radiological protection teaching is specific and fitted to each level: the course (1) has been given (optional or mandatory) since 1960 for more than 7500 students. Part of the learning process in radioprotection is only informative, because in this case the students are not allowed to ask the Argentinean Nuclear Regulatory Authority authorization for radioactive material handling. Course (2) has been taken by more than 800 physicians since 1962. Here, the students receive a very intensive training in radioprotection which includes: justification, optimization and dose limits; dosimetric magnitudes and units; internal and external dosimetry of 99m Tc, 201 Tl, 60 Co and other isotopes used in medicine; safety in occupational exposure; national and international legislation. Since 1962, more than 1000 graduates have attended course (3). In this case the training in radioprotection is as intensive as in course (2) with special focusing in 125 I, 3 H, 14 C, 32 P and other isotopes used in biomedicine. Course (4) has been given from 1992 and the objective is to up-date knowledge and the intensity of training depends on the requirements of each professional. Course (5) has been given since 1997 and it is mainly directed to the operational aspects of

    Full Text Available Debido a la importancia que la inocuidad de los alimentos entraña para la salud pública, se procuró determinar la calidad microbiológica de los alimentos que consumen los usuarios de los comedores comunitarios del conurbano de Buenos Aires, Argentina. Se trata de un estudio descriptivo, cuyo universo lo conformaron tres municipios con índices medianos y altos de pobreza, de los que se extrajo al azar una muestra de 52 comedores. La información se recolectó desde abril de 1994 hasta abril de 1995 inclusive, por medio de encuestas, observaciones directas y análisis microbiológicos del agua y los alimentos servidos. Los análisis del agua y los alimentos se ajustaron, respectivamente, a las recomendaciones del Código Alimentario Argentino y de la Comisión Internacional de Especificaciones Microbiológicas para Alimentos. Los resultados se interpretaron según los valores para alimentos cocidos acordados por el Grupo de Trabajo de Control de Alimentos. La parte microbiológica del estudio mostró que en 28 (54% de los comedores la comida o el agua era inadecuada y en 11 (21%, ambas eran inadecuadas. Bacillus cereus fue la bacteria patógena que se encontró con mayor frecuencia en los alimentos analizados. Los factores significativamente asociados con condiciones microbiológicas insatisfactorias de las comidas y el agua fueron no desinfectar el agua (P = 0,009, la falta de higiene en el ambiente (P = 0,03, la presencia de roedores e insectos (P = 0,05, el sistema de provisión de materias primas (P = 0,01 y un número de usuarios menor de 100 (P = 0,008.

    In this work, a recently developed urban-scale atmospheric dispersion model (DAUMOD-GRS) is applied to evaluate the ground-level ozone (O 3 ) concentrations resulting from anthropogenic area sources of NO x and VOC in the Metropolitan Area of Buenos Aires (MABA). The statistical comparison of model results with observations (including new available data from seventeen sites) shows a good model performance. Estimated summer highest diurnal O 3 1-h concentrations in the MABA vary between 15 ppb in the most urbanised area and 53 ppb in the suburbs. All values are below the air quality standard. Several runs are performed to evaluate the impact of possible future emission reductions on O 3 concentrations. Under all hypothetical scenarios, the maximum diurnal O 3 1-h concentration obtained for the area is slightly reduced (up to 4%). However, maximum diurnal O 3 concentrations could increase at some less urbanised areas of MABA depending on the relative reductions of the emissions of NO x and VOC. -- Highlights: ► A recently developed air quality model reproduces well observed O 3 levels in MABA. ► Modelled summer maximum diurnal O 3 concentrations vary in the area between 15 and 53 ppb. ► All hourly values are below the air quality standard (120 ppb). ► Possible future emission reductions would have small impact on the highest level. -- The distribution of summer maximum diurnal ground-level O 3 concentrations in the Metropolitan Area of Buenos Aires is evaluated applying a recently developed simple urban air quality model

    Due to the environmental influences on health, the goal of this study was to describe and compare the built environment in 3 socially contrasting neighbourhoods of Buenos Aires city.In 2011 a cross-sectional study was conducted in 3 socially contrasting neighbourhoods of Buenos Aires city: Recoleta (upper class), Almagro (middle class) and Constitución (lower class). Grocery stores and food stands were surveyed as well as all suitable spaces to perform physical activity. An analysis was conducted to assess the density of every food outlet per Km2 of each neighbourhood's area and per 10000 inhabitants. 2778 food stores and 149 outdoor physical activity facilities were surveyed. A higher density was observed in Constitución for fast food restaurants (Recoleta 3.6; Almagro 2.4; Constitución 6.7) and food stands (Recoleta 4.2; Almagro 1.2; Constitución 25.7) and a lower density for outdoor physical activity facilities. Population density and area density proved to be analogous. Statistically relevant differences were observed regarding the dimension of each food outlet: grocery stores, fruit stands, pubs, restaurants and food stands, as well as in the number of food stores and outdoor physical activity facilities. The information gathered in this study could be highly useful for public health policies on healthy lifestyles, and could eventually redefine the built environment in order to improve the city's equality regarding outdoor physical activity facilities and food stores.

Fue este un producto de importancia vital no sólo por su aplicación en las comidas cotidianas, sino también por su aplicación en la conservación de las carnes y los cueros. Las características de su uso y su obtención, aumentaron su valor, no sólo comercial sino también estratégico. El hallazgo de yacimientos locales permitió a los habitantes de Buenos Aires abastecerse mediante la práctica de expediciones periódicas que fueron promovidas por las autoridades capitulares, lo que les permitió ejercer un mayor control sobre dicha producción. Como la actividad requería una importante capacidad de transporte y de mano de obra, era una práctica aprovechada por muchos para emplearse en ella y para obtener benefi cios con el comercio que se generaba en la oportunidad. Esto convertía a las expediciones a salinas, organizadas por las autoridades de la ciudad, en grandes caravanas que se internaban en pleno territorio indí-gena, involucrando un amplio conjunto de actores sociales tanto de la ciudad como de la campaña y el mundo indígena

    A cross-sectional study was carried out on cats attending the Small Animal Hospital at the Faculty of Veterinary Sciences of the University of Buenos Aires to assess the prevalence and associated risk factors of Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) in the city of Buenos Aires, Argentina. Blood samples from 255 cats with symptoms compatible with FIV or FeLV infection, collected between 2009 and 2013 were analyzed by serology (immunochromatography, IA) and by hemi-nested PCR (n-PCR). The IA and n-PCR assays showed similar percentages of positivity for FIV while the n-PCR test was more sensitive for FeLV. Differences between the diagnostic tests and their choice according to the age of the animal are discussed. The clinical histories of ninety of the 255 cats showed blood profiles similar to others previously reported and revealed a higher risk of infection in male adult cats with outdoor access.

    The epidemiology of psychiatric disorders in children and adolescents has received little attention in Argentina. One of the problems related to the scarcity of such epidemiological research is linked to the lack of availability of diagnostic interview instruments which have been locally validated. The object of the study was to conduct a validation study of the DISC IV (Spanish version), administered by lay interviewers in the City of Buenos Aires. The sample was obtained from the Hospital de Niños "Ricardo Gutiérrez" in the City of Buenos Aires. Lay interviewers administered the DISC IV to 116 youngsters. Then psychiatrists re-administered the DISC IV a week later and immediately afterwards conducted a semi-structured diagnostic clinical interview. Participant in the sample ranged in age from 9 to 17. The sensitivity was 81.5% and the specificity 66.1%. The test-retest reliability was reasonable (Kappa 0.46 standard error 0.09). In general, the DISC administered by the non-professional interviewer was demonstrated to have the ability to discriminate between youngsters who suffer from psychiatric disorders and healthy youngsters. The confidence level was from moderate to good for the presence of a general psychiatric disorder as well as for disorders of specific states of mind, but for anxiety disorders and behaviour disorders the confidence level was poor.

    The TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego) is a 110-item questionnaire in five scales which has been translated into over 25 language versions: American, Italian (only for Interview version or TEMPS-I), French, Lebanese, Hungarian, Japanese and Turkish versions have already been validated. There are two Spanish versions, one from Barcelona, and the present one from Buenos Aires. This study represents the first attempt at validating the TEMPS-A in Spanish. 932 clinically well subjects were studied, of both sexes (62% female) with mean+/-SD age of 35.4+/-18.1. Standard psychometric tests of reliability and validation were performed. Chronbach alphas were 0.7 (depressive) and 0.8 (anxious, cyclothymic, irritable and hyperthymic). In exploratory factor analyses, the hyperthymic was distinct from the others. As expected, the depressive and anxious correlated strongly, so did the cyclothymic and anxious. Dominant temperaments ranged from 2.1% to 4.5% of the population under study, except for the hyperthymic which had a negligible rate of 0.2% (but accounted for 13% between +1 SD and +2 SD). We did not examine test-to-test reliability. This is the first validation of the TEMPS-A in Spanish, the Buenos Aires version with the original 110 items, with very good psychometric properties.

    The coastal cliffs of the Buenos Aires province (Argentina) have been the subject of intense paleontological studies since the XIX century. Therefore, many of the type localities in which is based the late Cenozoic Pampean biostratigraphic/chronostratigraphic scheme are located in this area. In this context, the sedimentites that crop out near the mouth of the Chocorí Creek contain a set of palaeontological sites that, because of their richness and well-preserved fossil content, hold high national and international importance. The aims of the present contribution are: 1) to make a stratigraphic and sedimentological characterization of the study area; 2) to list the fauna outcropped at these palaeontological sites and establish a biostratigraphic framework; 3) to elaborate a palaeoenvironmental model for the area. The study interval was informally subdivided into a lower, middle and upper interval. Interpretation was based on the presence of a number of key features such as architectural elements; channel:overbank ratio and palaeosol occurrence. The first two intervals were interpreted as continental deposits of a fluvio-alluvial nature and are the focus of this paper. The upper interval was related to foreshore marine deposits and will be studied in a future contribution. The lower interval is characterized mainly by overbank architectural elements in which calcisols and argillic protosols were identified. Channel-fill deposits are isolated and surrounded by fine-grained overbank successions and sedimentary structures are suggestive of mixed-load transport. The contact between the lower and middle intervals is an irregular, highly erosive surface characterized by a significant vertical change in the facies. This surface defines the base of multistorey sandbodies which's internal arrangement alongside with the low participation of overbank deposits suggests deposition by a braided fluvial system. Palaeosols and vertebrate fossils were used as palaeoclimatic

METODOLOGÍA: Se procesaron y analizaron fuentes estadísticas secundarias: se utilizaron dos encuestas domiciliarias que contenían un módulo sobre la utilización de servicios de salud y gastos asociados diseñado por el Ministerio de Salud y aplicado al Área Metropolitana de Buenos Aires en 1989 y 1995. RESULTADOS: Se constató un aumento del carácter socialmente regresivo del gasto de bolsillo en medicamentos entre 1989 y 1995, en un mercado farmacéutico que ha duplicado sus precios medios en el nuevo contexto de liberación de precios y apertura de las importaciones. Esta regresión se manifestó en el crecimiento del gasto directo de la compra de medicamentos, el aumento de la parte correspondiente a los medicamentos en la estructura del gasto privado para la salud y el incremento desigual del peso relativo de dicho gasto en los ingresos familiares. CONCLUSIONES: El gasto de bolsillo en medicamentos resulta un indicador eficiente de equidad financiera para el estudio de la protección de la población urbana argentina frente al riesgo de enfermar, y puede contribuir a la adecuación del marco regulador del mercado farmacéutico, mediante la incorporación de criterios sociales de evaluación a la ecuación farmacológica de seguridad y eficacia terapéutica.OBJECTIVE: To assess the level of equity in drug consumption patterns in the Metropolitan Area of Buenos Aires, Argentina, given the transformation of the Argentine pharmaceutical market since the deregulation of the country's economy in 1991.

    Full Text Available Cerca del 40 % del área sembrada con trigo en Argentina se concentra en el sur de la provincia de Buenos Aires. Los eventos frecuentes de temperaturas extremas frías en la segunda quincena de octubre, coincidentes con un momento fenológico sensible del trigo, provocan daños de importancia en el cultivo. El presente trabajo tiene como objetivo proveer mapas de riesgo de temperaturas extremas frías para el período sensible del cultivo de trigo en esa región. Se utilizó información de los canales 3, 4 y 5 del satélite NOAA de 1,09 km² de resolución espacial, obtenidas en el Instituto de Clima y Agua del INTA-Castelar entre 2005 y 2008, y datos diarios de temperaturas mínimas del período 1961-2008 de 13 estaciones de superficie del Servicio Meteorológico Nacional (SMN y del Instituto Nacional de Tecnología Agropecuaria (INTA. Los resultados muestran que las áreas de mayor riesgo son aquellas que combinan menor altura sobre el nivel del mar y al mismo tiempo mayor distancia al mismo. Esta metodología puede ser extendida a otros cultivos y a otras regiones. Este tipo de análisis constituye una herramienta que puede ser útil en tareas de planificación tanto a nivel estatal como privado.Cold temperature can cause severe damage in crops when a cold front irruption occurs. This is especially true in some specific periods on the growing crops mainly during spring. This work presents frost risk maps for wheat.

    Resumen Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos (“teteras”), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país.

    Full Text Available From the perspective of urbanism, the beginning of the twenty-first century in the metropolitan region of Buenos Aires has been characterized for the emergence of large-scale projects developed by private actors. Among them stand out private cities and commercial and services areas, called new centralities. Both urban designs are in close connection and require effective mobility conditions for its concretion. The intervention of private agents has impacted in the territorial transformations, creating a "parallel urban system" in the region, oriented towards attracting residents with a high socio-economic status. However, the traditional network of cities has not disappeared and, with the juxtaposition of this new system of private urbanism, it deepened the conditions of spatial fragmentation and social segregation. Desde la perspectiva del urbanismo, el comienzo del siglo XXI se caracteriza por la aparición en la región metropolitana de Buenos Aires, de proyectos de gran envergadura desarrollados por agentes privados. Entre ellos sobresalen las ciudades privadas y las áreas comerciales y de servicios, denominadas nuevas centralidades. Ambos diseños urbanos se mantienen en estrecha relación y requieren de eficaces condiciones de movilidad para su concreción y para su exitoso funcionamiento. La intervención de los agentes privados ha impactado en las transformaciones territoriales, creando un “sistema urbano paralelo” en la región, orientado a la captación de residentes con un alto nivel socio-económico. No obstante, la red de ciudades pre-existente no ha desaparecido y con la yuxtaposición de este nuevo sistema de urbanismo privado, se profundizan las condiciones de fragmentación espacial y de segregación social.

Se utilizan datos de una investigación cualitativa en hombres adolescentes de dos estratos socioeconómicos: bajo y medio-alto residentes en el Área Metropolitana de Buenos Aires (AMBA. Uno de los hallazgos muestra que la concepción sobre un deseo sexual masculino arrollador y mayor que el deseo sexual femenino, si bien se justifica principalmente desde argumentos de tipo esencialistas, también se justifica desde argumentos sociales o desde una combinación de ambos. Un determinismo social, o un determinismo combinado entre argumentos sociales y biológicos también pueden orientar hacia una naturalización de las relaciones sociales que obstruyen la posibilidad del cambio individual y del cambio social.The aim of this article is to analyze social representations of male adolescents about the meaning of being a boy and the implications for their sexual interactions. To that purpose we examine data from a qualitative research among male adolescents from two socioeconomic strata: low and middle-low residents from the Metropolitan Area of Buenos Aires (AMBA. The data show that the conception about a male desire greater than the female desire is in great part justified by essentialist arguments (biological reasons. However, this conception is also justified by social arguments or a mix of social and essentialist arguments. A social determinism, as well as a mix between social and biological arguments, might guide to a naturalization of sexual relations that could obstruct individual and social change.

    A paleoenvironmental reconstruction of the southeast coast of Buenos Aires province, Argentina, is made mainly on the basis of paleontological and paleoichnological studies, supported by sedimentological analyses and radiocarbon dating. Continental late Pleistocene and continental, transitional, and marine Holocene stratigraphic units are identified. The former comprises fossil mammals and ichnites of 16000-12,000 BP. The continental early Holocene time, ca. 8100 BP, is represented by an interdune paleoenvironment in which shallow brackish ponds were colonized by diatoms, fish, rodents, and birds. A transitional paleoenvironment in the middle Holocene—6930-6570 BP—is recorded by deposits formed by estuarine crabs. During the late Holocene, between 5000 and 4800 BP, a marine transgression was recorded by a rich mollusc fauna.

    The study of carrion fauna associated with buried human corpses from a forensic perspective could provide useful information in criminal investigations. Insects and other arthropods remains sampled of 44 legally exhumed infant skeletons from La Plata (Buenos Aires, Argentina). They were identified at different taxonomic levels depending on the state of preservation. The specific diversity, abundance and frequency were analyzed and each taxon was assigned to the hypothetical colonization sequence: burial colonization, post-exhumation contamination at cemetery deposit or soil fauna. The phorid Dohrniphora sp. is mentioned for the first time in Argentina as carrion fauna of underground colonization, and the assemblage of Dohrniphora sp., Megaselia scalaris and Hydrotaea aenescens is proposed as indicator of buried cadavers. These findings provide new useful data to be applied in forensic entomology research. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    A ground-based differential Absorption Lidar (DIAL) system has been implemented at CEILAP laboratory, located in the Buenos Aires industrial suburbs, The goal was to perform measurements of the stratospheric ozone layer. Since early 199 systematic measurements of zone concentration profiles from approximately 18 to 35 km altitude are performed. Our measurements are carried out in 5 hours in average during the night and in cloudless conditions. The DIAL system allows us to calculate directly the ozone profile from the lidar backscattering radiation since it is a self- calibrating technique. The signals processing takes into account the influence of the temperature profile on the ozone cross section. The temperature data is obtained from the radiosondes measurements performed at Ezeira International Airport. The evolution of the stratospheric ozone profile is studied for different months. Results are compared with the data obtained by different satellites like SAGE II and HALOE. The spatial and temporal range of the satellites must be taken into account.

    As part of pioneering efforts to assess the potential of native microalgae as biofuel feedstock in South-Eastern Buenos Aires, 34 monoalgal cultures (corresponding to the Phylum Chlorophyta) were established and 21 were selected for further growth and biomass composition characterization. Novel RNA sequences in the ITS1-5.8S-ITS2 region were identified. Some strains showed desirable traits as biodiesel feedstock such as (i) apparent maximal doubling times of 6h, (ii) lipids accumulation of up to 43% of their dry biomass, (iii) high ration of mono-unsaturated to poly-unsaturated fatty acids, (iv) high response to CO(2) supplementation, and (v) complete sedimentation in 4h. Data of the outdoors performance of some strains suggested they might represent valuable resources for future research towards the regional development of the technology for microalgae-based biofuels.

    Full Text Available This paper develops an alternative sanitation to the negative environmental impacts caused by the intensification of the production system and the inadequate management of waste from a dairy farm with 1050 cows, belonging to Trenque Lauquen, Buenos Aires Province of Argentina. Anaerobic digestion technology allows the biological degradation of organic material in an oxygen free environment and it is proposed to develop a treatment system that allows evaluation of the products obtained through electricity generation and biofertilizer. The working methodology includes an analysis of preliminary data from anaerobic digestion of cattle manure, characterization of the generated waste, the design of the treatment system and a technical economic analysis. This study shows that it is possible to reach the dairy sanitation with energy benefits developing a sustainable resource and environmental management

    The early twentieth century saw the rise of vacation camps for frail children as educational and health-giving experiences provided by medical and philanthropic organizations. This article analyzes some of these early experiences, seen here as the predecessors of social tourism, in the Province of Buenos Aires. A combination of written sources are examined, mainly institutional reports, periodicals such as the Monitor de la Educación Común - published by the Consejo Nacional de Educación (National Board of Education) - or laws, with photographs and plans for different examples. I argue that these buildings were both physical and cultural "brands" in the places where they were located, and that their architectural structure encapsulated ideas about leisure space and cures in unique natural environments.

Se evaluaron 83 ancianos y 76 jóvenes de 71.9±8.1 y 29.8±6.6 años respectivamente, mediante la medición de 25(OHD, parathormona medio-molecular y de marcadores del metabolismo óseo y mineral. En invierno se comprobaron valores de 25 (OH D en grado de insuficiencia en ambos grupos y un 14.2% de ancianos y 15.9% de jóvenes con valores menores de 10 ng/ml. En verano se observó un incremento de la 25(OHD en toda la población, sin embargo los niveles circulantes de Vitamina D no superaron los 40 ng/ml, en ambos grupos. Los niveles plasmáticos de parathormona fueron más elevados en ancianos que en jóvenes y en esa subpoblación se observó la presencia de hiperparatiroidismo secundario. La elevación de parathormona está condicionada por la deficiencia de vitamina D y otros factores adicionales como la edad, la insuficiencia renal y el grado de nutrición de la población. La remodelación ósea presentó variaciones estacionales: se incrementó en invierno en ambos grupos. En la ciudad de Buenos Aires se han observado niveles descendidos de Vitamina D en jóvenes y mayores, durante todo el año.

    Liniscus diazae n. sp. (Nematoda: Trichuridae) is described from the urinary bladder of Oxymycterus rufus and Akodon azarae (Cricetidae: Sigmodontinae) from Buenos Aires Province, Argentina. Liniscus diazae can be differentiated from its congeners by having a much longer spicule and without an elevated vulva. In addition, L. diazae can be distinguished from L. incrassatus and L. himizu by having a longer body length. Males are similar in posterior width to L. papillosus and L. himizu, but thinner than L. incrassatus and L. maseri. This is the second record of a capillarid from mammals in Argentina. An updated list of capillarid species of rodents and insectivores from North America, with their synonyms, hosts, sites of infection, and geographic distribution, is provided.

    Full Text Available El proceso histórico 1930-1946 en la Argentina se caracteriza por la ampliación intervencionista del Estado, producto del crac neoyorquino de 1929, que pone fin al paradigma del crecimiento hacia afuera. Es un contexto de importantes transformaciones donde el intervencionismo se combina con el fraude electoral para dar lugar a un estricto control social, sin renunciar al país agropecuario. Las políticas públicas implementadas interpelan a los ciudadanos como productores y el intervencionismo adquiere un carácter transformador de las prácticas productivas y del medioambiente. El análisis del Anuario Rural de la Provincia de Buenos Aires, difundido por el Ministerio de Obras Públicas, permite comprender el proceso del Estado intervencionista, como expresión de la ampliación del Estado en sus aspectos técnicos y burocráticos

    Full Text Available Este trabajo analiza las formas de pobreza existentes en la ciudad de Buenos Aires durante el período 1785-1821. Para ello se trazará un perfil social de quienes apelaron a la Real Audiencia -luego Corte de Apelaciones- para ser declarados pobres solemnes y poder litigar sin gastos. Mediante un enfoque prosopográfico se examinará de qué modo distintas variables -tales como el género, la "raza", el estado civil y la ocupación- incidían en la vida de los peticionantes, distinguiendo las causas más frecuentes de descenso social. También se analizarán historias de vida concretas para iluminar tendencias generales, y dar cuenta de las prácticas desplegadas por individuos provenientes de diversos sectores sociales en pos de atenuar sus carencias y defender sus derechos.

    Full Text Available A partir de una investigación etnográfica llevada a cabo en un barrio del Área Metropolitana de Buenos Aires, caracterizado por altos índice de pobreza, vulnerabilidad y marginalidad, en este texto se describen y analizan, desde la perspectiva de las propias usuarias, las caracterísiticas y formas en que el consumo intensivo de PB/paco moldea las dinámicas emocionales vinculadas con la maternidad. En el marco de esta relación consumo-maternidad, destacamos distintos momentos entre los que se encuentran las "emociones maternales en suspenso" vividas durante el consumo intensivo ("giras"; los malestares emocionales asociados a la "culpa" y la "vergüenza" durante el "bajón"; y las emociones maternales intensificadas asociadas a un intenso apego emocional con los hijos y las hijas, sobre todo cuando comienzan a "rescatarse".

    Full Text Available OBJETIVO: Medir la equidad manifestada por los patrones de consumo de medicamentos en el Área Metropolitana de Buenos Aires, Argentina, a la luz de las transformaciones operadas en el mercado farmacéutico argentino después de la desregulación de la economía en 1991. METODOLOGÍA: Se procesaron y analizaron fuentes estadísticas secundarias: se utilizaron dos encuestas domiciliarias que contenían un módulo sobre la utilización de servicios de salud y gastos asociados diseñado por el Ministerio de Salud y aplicado al Área Metropolitana de Buenos Aires en 1989 y 1995. RESULTADOS: Se constató un aumento del carácter socialmente regresivo del gasto de bolsillo en medicamentos entre 1989 y 1995, en un mercado farmacéutico que ha duplicado sus precios medios en el nuevo contexto de liberación de precios y apertura de las importaciones. Esta regresión se manifestó en el crecimiento del gasto directo de la compra de medicamentos, el aumento de la parte correspondiente a los medicamentos en la estructura del gasto privado para la salud y el incremento desigual del peso relativo de dicho gasto en los ingresos familiares. CONCLUSIONES: El gasto de bolsillo en medicamentos resulta un indicador eficiente de equidad financiera para el estudio de la protección de la población urbana argentina frente al riesgo de enfermar, y puede contribuir a la adecuación del marco regulador del mercado farmacéutico, mediante la incorporación de criterios sociales de evaluación a la ecuación farmacológica de seguridad y eficacia terapéutica.

  8. Long-Term Trends and Variability of Water Levels and Tides in Buenos Aires and Mar del Plata, Argentina

    Full Text Available We present an analysis of the long-term trends and variability of extreme water and tidal levels and the main tidal constituents using long-term records from two tide gauges in the wider region of the Rio de la Plata estuary: Buenos Aires (1905–2013 and Mar del Plata (1956–2013. We find significant long-term trends in both tidal levels and the main tidal constituents (M2, S2, K1, O1, and the overtide M4 from a running harmonic analysis in both locations. The tidal range decreased on average 0.63 mm y−1, as a result of an increase of the low water levels and a decrease of the high water levels. We also find a secular decrease in the amplitude of the semi-diurnal constituents and an increase of the diurnal ones, but of different magnitudes at each location, which suggests that different processes are producing these changes. In Buenos Aires, an increase of river discharge into the estuary seems to reduce the tidal range by hampering the propagation of the tidal wave into the estuary, whereas no influence of river discharge on water and tidal levels can be detected in Mar del Plata. We believe that other factors such as thermohaline changes or the rise of mean sea-level may be responsible for the observed tidal range decrease. Despite the tidal long-term trends, we find no significant trends in the meteorological component of the tide-gauge records other than an increase in the mean sea-level. In addition, we explore teleconnections between the variability of the meteorological component of the tide-gauge records and climate drivers.

    The Sistema de las Encadenadas de Chascomus (35 o 30'S-35 o 34'S; 58 o 17'W-58 o 44'W) lies in the geomorphologic unit called Pampa Deprimida in the Buenos Aires province, Argentina. The Pampa Deprimida has wet climate, with mean annual precipitation about 900 mm, mean annual temperature ranging 13-16 o C and alternating of multiannual dry and humid periods (Iriondo and Drago, 2000). Although rainfall is higher in summer, the precipitation-evaporation balance is negative for this season. This system is located in the Salado River drainage basin, a sedimentary basin where Cretaceous, Tertiary, Plio- Pleistocene and Pleistocene sediments are superimposed over the Precambrian crystalline basement. The Pampeano Plio-Pleistocene sediments contain the aquifer unit and consist in a succession of silt-stones and fine sandstones with a relatively homogeneous mineralogical composition, consisting primarily of plagioclase, quartz and volcanic glass (Teruggi, 1957). Such sediments have generally been regarded as eolic in origin, being derived from volcaniclastic deposits outcropping in the Andes over 1000 km to the west, although localized fluvial and mass movement processes probably redistributed the material to a large extent once accumulated in the Pampas (Kemp and Zarate, 2000). The Sistema de Las Encadenadas de Chascomus is formed by interconnected shallow lakes being the principal ones Vitel (13 km 2 ), Chascomus (30 km 2 ), Manantiales and Adela (21 km 2 ), El Burro (10,7 km 2 ),Chis Chis (14.8 km 2 ), Las Tablillas (16,7 km 2 ) and Las Barrancas (8,85 km 2 ). The Horqueta stream connects the last one, and in fact the whole system, with the Salado River. Pampasic lakes are shallow alkaline systems, with nearly continuous vertical mixing that promotes a high concentration of suspended particulate matter and low water transparency. Water column is almost always thermally homogeneous, saturated with dissolved oxygen and with a high content of dissolved organic matter

    Full Text Available OBJECTIVES: To estimate antigen-specific and series-complete vaccination coverage among children aged 13 to 59 months in Buenos Aires; to compare the results of a community-based household survey with coverage rates obtained from administrative records; and to identify risk factors for incomplete vaccination. METHODS: Census tracts in Buenos Aires were surveyed systematically in March and April, 2002. Three children aged 13 to 24 months and 25 to 59 months were surveyed per block in each census tract. Written documentation of vaccination was required. Risk factors associated with incomplete vaccination were identified with univariate analysis and multivariate logistic regression. RESULTS: A total of 1391 children were surveyed. Antigen-specific coverage ranged from 69.4% (95% CI 66.7%-72% for Haemophilus influenzae type b vaccination to 99% (95% CI 98.4%-99.6% for BCG vaccination.

Há diversos métodos para determinar a rugosidade, mas muitos são caros ou de operação de campo complexa. Neste trabalho, é apresentado um método versátil e econômico que usa máquina fotográfica e tela quadrada. Cada fotografia é processada numericamente obtendo a altura RMS, como parâmetro da rugosidade da cobertura. Por meio de técnicas geoestatísticas de krigagem é estimada a distribuição espacial da rugosidade. São mostradas experiências em áreas com cobertura de trigo, localizadas na área agrícola serrana da Província o Buenos Aires, Argentina. Os valores de RMS encontrados (29 mm Use of SAR images for soil surface moisture estimation requires taking into account the other factors that influence the radar backscattering signal, among which the surface cover roughness at centimeter scale is very important. There are several methods to determine the roughness, but many are expensive or complex field operation. A versatile and economic method that uses a photographic camera and a girded screen is presented. Each picture is numerically processed obtaining the RMS height, as parameter of the crop-soil complex roughness. By means of krigging geostatistics techniques the spatial distribution of roughness is estimated. Experiences in parcels with wheat cover, located in the hill agricultural area of Buenos Aires Province, Argentina are shown. The found RMS values (29 mm < RMS < 48 mm are analyzed with four roughness approaches. Their utility in order to estimate soil surface moisture status in agricultural parcels by means of their application like input into the SAR images backscattering models is stated.

    Full Text Available Este artigo analisa os momentos iniciais do ensino de economia na Argentina, a partir de um exame dos materiais ligados às cátedras de economia política e de finanças, que se constituíram por ocasião do surgimento da carreira de direito na Universidade de Buenos Aires. O recorte temporal diz respeito ao período definido pelas crises econômicas de 1873-1875 e a de 1890, já que tais conjunturas críticas são consideradas o elemento criador de uma demanda por saberes especializados, o que, por sua vez, contribui com a institucionalização e a legitimação desses saberes. Analisar o tipo de economia que se ensinava na Faculdade leva ao estudo da recepção de trabalhos produzidos em outros contextos nacionais e que foram, na Argentina, utilizados como referência legitimadora. Argumenta-se que, embora na Argentina de fins do século XIX o liberalismo econômico possa ser entendido como parâmetro de autoridade amplamente aceito, a recepção das obras canônicas da época, especialmente no caso daquelas provenientes da escola liberal francesa, foi um processo criativo que serviu para validar opiniões muitas vezes diversas em relação àquelas que os próprios autores franceses sustentavam.This article analyzes the inaugural period of teaching economics in Argentina, examining material linked to the chairs of political economy and finance created around the time of the institution of the legal career at the University of Buenos Aires. The time period under study is defined by the economic crises of 1873-1875 and 1890, since these critical phases are generally held to be responsible for creating the demand for specialized knowledge, which in turn contributed to the institutionalization and legitimization of these specialities. Analyzing the type of economics taught at the Faculty leads into a study of how works produced in other national contexts were absorbed and deployed in Argentina as legitimizing points of reference.

    Full Text Available A census of spiders was undertaken in winter wheat fields of Buenos Aires province, Argentina, as well as from their margins and from wheat stubble. Spiders were collected weekly over 3 consecutive years using entomological sweeping and pitfall traps. Field margins were the richest and densest habitats (H'= 3.27, J'= 0.82 and registered 52 species from 14 families, while 31 species from 13 families were found in wheat. Thomisidae and Araneidae were the most abundant families in the herbaceous layer of both the margins and the crop, and Lycosidae in the soil litter. In contrast, 17 species from 8 families were recorded from wheat stubble, making it the least diverse habitat surveyed (H'= 1.67, J'= 0.72. These results could be related to repeated disturbance of wheat fields by harvest, tillage and other field work. Furthermore, the similarity observed in the families of both margin and crop communities indicates that colonization of wheat fields is from the adjacent areas.Se realizó un censo de arañas en cultivos de trigo de invierno de la provincia de Buenos Aires, Argentina, así como en sus márgenes y en el rastrojo.

    Full Text Available In 2003, the incidence of tuberculosis in Argentina showed an increase compared to 2002. The severe national crisis at the end of the 90s has probably strongly contributed to this situation. The goal of this work was to estimate the extent of the spread of the most predominant Mycobacterium tuberculosis strains and to assess the spread of predominant M. tuberculosis clusters as determined by spoligotyping and IS6110 RFLP. The study involved 590 pulmonary, smear-positive TB cases receiving medical attention at health centers and hospitals in Northern Buenos Aires (NBA suburbs, from October 2001 to December 2002. From a total of 208 clinical isolates belonging to 6 major clusters, 63 (30.2% isolates had identical spoligotyping and IS6110 RFLP pattern. Only 22.2% were shown to have epidemiological connections with another member of their respective cluster. In these major clusters, 30.2% of the 208 TB cases studied by both molecular techniques and contact tracing could be convincingly attributable to a recently acquired infection. This knowledge may be useful to assess the clonal distribution of predominant M. tuberculosis clusters in Argentina, which may make an impact on TB control strategies.La incidencia de la tuberculosis en Argentina mostró en 2003 un incremento en comparación con 2002.

En menor proporción se registraron pipas de caolín y elementos metálicos. El análisis del contexto permite ubicar la ocupación en la segunda mitad del siglo XIX. A partir de las evidencias tanto documentales como arqueológicas, se interpreta al sitio como un área de consumo y descarte de grupos criollos, relacionado con las tareas pecuarias desarrolladas en el establecimiento productivo. Las evidencias de la utilización antrópica en el material óseo (marcas de corte, fracturas intencionales y señales de termoalteración se registran exclusivamente en la fauna doméstica, Ovis aries y Bos taurus. Estas especies son las de mayor representación en la muestra y se infiere un uso diferencial de las mismas.

La fotografía, que con su exactitud superaba la habilidad manual de cualquiera de los pintores instalados en el país en ese momento, fue acogida con entusiasmo por la sociedad porteña. Sin embargo, el elevado precio que debía pagarse por pasar a la inmortalidad hizo, que la fotograf ía en sus primeras dos décadas fuera un lujo reservado solamente a las clases acomodadas. Lejos de la instantaneidad de las imágenes actuales, los retratos al daguerrotipo implicaban largos tiempos de exposici ón y esto significaba que eran ante todo posados. Estas primeras imá- genes pueden ser consideradas, entonces, como documentos que sirven para reconstruir los contenidos de la mentalidad burguesa en el Río de la Plata a mediados del siglo XIX. Estos retratos eran el resultado del esfuerzo de estas elites por imponer al futuro una determinada imagen de sí mismas. A través de la puesta en escena, decidida de común acuerdo entre el fotógrafo y el retratado, la burguesía rioplatense transmitía a la posteridad mensajes, ideas, prejuicios, comportamientos y modos de ver muy específicos de su clase.Ever since the introduction of the daguerreotype to the Río de la Plata region in 1840, formal studio portraits became daguerreotypists . main source of income. This novelty, which made it possible to obtain likenesses more exact than those produced by the portrait painters settled in the country by that time, was warmly welcomed by the Buenos Aires society. Nevertheless, at the peak of the daguerreotype period in the 1850.s, photography was an expensive luxury that only members of the higher classes could afford. Unlike today.s candid portraits and due to the technological limitations of the process, daguerreotype portraits required long exposure times and sophisticated poses.

Of the 33 RSAT positive, 17 (51.5% blood cultures were done, and B. canis were isolated from 2 cases. Since infected dogs have been shown to remain bacteremic for prolonged periods, our results also suggest a risk of human infections in this area.La brucelosis canina causada por Brucella canis es una infección que afecta el tracto reproductivo de los perros y que puede provocar abortos en las hembras, infección de los órganos sexuales en los machos e infertilidad en ambos sexos. Se desconoce la prevalencia de esta enfermedad y las medidas de control se aplican sólo en algunos criaderos comerciales. Durante un programa de castración gratuita de perros llevado a cabo en el Partido de Lomas de Zamora (Gran Buenos Aires se realizaron estudios clínicos, serológicos y bacteriológicos en 224 animales. En la población estudiada, la prueba de microaglutinación rápida en portaobjetos (RSAT resultó positiva en suero de 33 (14,7% perros y fueron confirmadas por IELISA en 24 (10,7% de ellos. A 17 de los 33 perros positivos mediante RSAT (51,5% se les practicaron hemocultivos y en 2 casos se aisló B. canis.

    In this work, a recently developed urban-scale atmospheric dispersion model (DAUMOD-GRS) is applied to evaluate the ground-level ozone (O3) concentrations resulting from anthropogenic area sources of NOx and VOC in the Metropolitan Area of Buenos Aires (MABA). The statistical comparison of model results with observations (including new available data from seventeen sites) shows a good model performance. Estimated summer highest diurnal O3 1-h concentrations in the MABA vary between 15 ppb in the most urbanised area and 53 ppb in the suburbs. All values are below the air quality standard. Several runs are performed to evaluate the impact of possible future emission reductions on O3 concentrations. Under all hypothetical scenarios, the maximum diurnal O3 1-h concentration obtained for the area is slightly reduced (up to 4%). However, maximum diurnal O3 concentrations could increase at some less urbanised areas of MABA depending on the relative reductions of the emissions of NOx and VOC. Copyright © 2012 Elsevier Ltd.

    In 1864, Lucio V. Mansilla y José Manuel Estrada created the Círculo Literario in Buenos Aires, Argentina, which endured until 1866. This cultural association shared the same concerns than other contemporary entities, also enacted by other men in the cultural life of Buenos Aires at that time. The Círculo Literario aspired to be an association that could gather politicians and men of culture, from different generations and political factions. The article examines the practices and initiatives of this cultural association, in a moment in which the Argentine culture was conceived as an open field for pioneers. The article evaluates the scope and the limits of this cultural entrepreneurship born outside from the State politics.

    Full Text Available This article addresses the issue of the city as tourist destination, specifically in relation to metropolitan configurations and dynamics. The article analyzes a tourist destination -the town of Tigreas part of the Metropolitan Area of Buenos Aires and its incorporation into the so called “Buenos Aires tourist destination”. The role of the tourist resort in the metropolitan context is analyzed beginning with the recognition of the paucity of studies on the subject at this scale. The article focuses on the analysis of the processes that lead to the establishing of the town as a tourist destination, assuming that this character is the result of specific actions to adapt the locality to tourist requirements. This focus questions the widespread approaches that assume the “tourist vocation” of localities as natural.

    The aim of this study was to compare the prevalence of molar incisor hypomineralization (MIH) among children with different health care coverage in Buenos Aires and Montevideo. An observational, cross-sectional and descriptive study was designed, considering children born from 1993-2003 who were seen in the Chairs of Comprehensive Children's Dentistry (Universidad de Buenos Aires) and of Pediatric Dentistry (Universidad de la República) and at five private dental offices between April and December 2010. Two groups were defined: A (Buenos Aires; n=1,090) and B (Montevideo; n=626). The clinical diagnosis was carried out with calibrated examiners (Kappa: 0.94) using the Mathu-Muju and Wright criteria. The prevalence of MIH was found to be 16.1% in A and 12.3% in B (p=0.03), with statistically significant differences between the public and private care sectors in both groups (A p=0.0008; B p=0.0004) and a positive correlation between MIH and year of birth (A p=0.001; B p=0.005). The results show that MIH is an emerging pathology and that MIH prevalence is related to year of birth and access to health care.

    Full Text Available The use of renewable energies requires a precise and detailed quantification of the resource available. Because of the cost of solar stations or limited availability of skilled human resources, in most emerging countries, this assessment is made only on a few points scattered over large areas. We report here a simple and inexpensive method to evaluate the photovoltaic (PV potential for a specific geographic region and a given PV capture technology. The system allows for a direct evaluation of the energy actually obtainable by scaling the measurement array of photovoltaic cells. The proposed measurement system can be installed as a stand-alone unit, or as part of a measurement network, connected to a more sophisticated central hub. The measurement station consists of said PV array (or similar PV array, a resistor, and a portable data logger. The system is calibrated with a device composed of a small array of PV cells, a resistor load bank, and two multimeters. Due to its low cost, this system can be replicated as many times as required with minimal investment. This would make it possible to evaluate the available photovoltaic potential of large regions with accurate and detailed data. Measurements carried out in Buenos Aires and in Antarctica confirm the consistency of the method.

In the present work, 54/843 enterobacteria collected in a teaching hospital of Buenos Aires city were ampicillin-sulbactam-resistant isolates remaining susceptible to second-and third-generation cephalosporins. The enzymatic mechanisms present in the isolates, which were also amoxicillin-clavulanic acid (AMC-resistant (18/54 were herein analyzed. Sequencing revealed two different variants of blaTEM-1, being blaTEM-1b the most frequently detected allelle (10 Escherichia coli, 3 Klebsiella pneumoniae, 2 Proteus mirabilis and 1 Raoultella terrigena followed by blaTEM-1a(1 K. pneumoniae. Amoxicillin-clavulanate resistance seems to be mainly associated with TEM-1 overproduction (mostly in E. coli or co-expressed with OXA-2-like and/or SHV ß-lactamases (K. pneumoniae and P. mirabilis. A new blaTEMvariant (TEM-163 was described in an E. coli strain having an AMC MIC value of 16/8 µg/ml. TEM-163 contains Arg275Gln and His289Leu amino acid substitutions. On the basis of the high specific activity and low IC50 for clavulanic acid observed, the resistance pattern seems to be due to overproduction of the new variant of broad spectrumß-lactamase rather than to an inhibitor-resistant TEM (IRT-like behavior.

    2016-01-01

    This paper explores the online expressions of violence perpetrated or experienced by adolescents from marginalized areas of Greater Buenos Aires, Argentina. Using a qualitative methodology, four specific events were examined: threats, "bondis" [fights], cyberbullying and displays of mourning. To do so, 20 in-depth interviews and 3,000 virtual observations of profiles in the social network Facebook were carried out. Among the main results, it was seen that most expressions of violence are part of an offline-online dynamic. Empirical evidence is also offered based upon which it can be affirmed that the expressions of violence of these teenagers are developed around the culture of "aguante" [fierce loyalty]. The article ponders the extent to which, in the iconic platform of the option "like," these expressions are implicitly functional to the social network or, to the contrary, or whether they allow displacements and significant reappropriations on the part of users. New questions arise about the use of these tools by adolescents from marginalized areas and the need for more complex approaches to examine these phenomena.

    Full Text Available This paper delves into the functioning of the Buenos Aires border from an analysis of various Comandancias de Fronteras, mainly those located in Pergamino and Magdalena (on the north and the south of the jurisdiction emphasizing the articulated efforts between the regular military forces and militia forces to conduct defensive practice. The period examined (1752-1780 covers the years between the implementation of the Comandancias until the defensive reforms introduced by the viceroy Vértiz, that have upset some basic features of our object of study. We are interested in the forming process of this boundary, the practices that gave life to it, the social subjects that emerged in this process and the conflicts they were part of. We follow the path of some Major Sergeants of militias, in particular, Diego Trillo in Pergamino and Clemente López Osornio in Magdalena, as examples of a local authority based on the legitimacy provided by the exercise of the "defense".

    Full Text Available Between 1890 and 1910, first as fear and later as a reality, anarchist attacks made its appearance in Buenos Aires. There are several questions about these phenomenons: How can they be understood? How should they be categorized? What caused them and how were they presented by the anarchist press? In this paper, a research of primary resources will lead us to examine the categories that are frequently used to describe these attempts: “political terrorism”, “propaganda by the deed”, “vindictive acts”. We will question the historiographical appropriateness of the categories “terrorism” and “propaganda by the deed”, concepts that anticipate the existence of a political aim in these events. We will verify that Anarchist attacks were driven by a passionate impulse, rather than political revolutionary motivations: they were acts of revenge with no intention of spreading the revolutionary message, but to murder those thought of being responsible for repression and injustice. Additionally, we will observe that the passionate perception prevailed also in the Libertarian press, and even though the attacks were celebrated, it was because they were acts of vengeance, and not because they were revolutionary.

    Full Text Available Este artículo explora dos mercados en dos continentes diferentes, el “Mercado Solidario Bonpland” en Buenos Aires (Argentina y el “Mercado de los agricultores del centro socio-cultural WUK” en Viena (Austria, con el propósito de indagar en las dimensiones simbólicas de las prácticas de la vida cotidiana, que se desarrollan en estos mercados. La particularidad es que estos mercados fueron originados y sostenidos por grupos de activistas locales para promover y apoyar la participación y el intercambio social. Aunque estos dos mercados difieren en su apariencia, los significados y las ideas conceptuales detrás de cada uno, reflejan propuestas similares hacia la consolidación de prácticas culturales alternativas, lo que conduce a que los mercados se tornen como lugares de intercambio y encuentro social relevantes para la comunidad local. En el artículo se abordan las “prácticas de intercambio” halladas en los mercados como acciones estratégicas que permiten obtener un medio de vida y un espacio de pertenencia social. Los actores involucrados en la producción de los mercados analizados, muestran a la performatividad como una faceta esencial de la producción de significados simbólicos, con la capacidad de generar un espacio para el fomento y desarrollo de posibles prácticas emancipatorias.

  12. Housing transformations Buenos Aires Metropolitan Area. The passage from Neo-liberalism to Urban Neo-development

    2014-12-01

    Full Text Available The economic recovery that followed the 2001/02 crisis in Argentina came with a relevant improvement in a number of social and economic indicators, related among other reasons to the design of public policies aimed at recuperating employment levels and the productive matrix. In this context, the “construction – public works” tandem became a central topic in the agenda, and Real Estate expansion was widely assessed as a positive outcome by macro-economic standards. However, this process was not exempt of contradictions, as can be seen in the metropolitan area of Buenos Aires, where it is possible to observe a set of concurring tendencies resulting from the hybridization of the urban neo-liberalization still present and the recent expansion of urban neo-developmentalism. As a result, the expansion of State-led de-commodification of goods and services aimed at social reproduction, coexists with a persisting process of socially regressive housing space production, together with an intense commodification of existing housing, associated with a growing financializationof “bricks”.

    2009-01-01

    The violence in its different forms, is a social problem that calls for multidisciplinary approaches in actions aimed at prevention. Among the skills needed to guide preventive policies, the highlights are risk and protective factors for violent behavior. This study aims to contribute, from the psychiatric perspective, in exploring factors influencing the behavior of homicidal adolescents. We studied a group of cases (n = 15) of young killers and a control group (n = 35) of juveniles who committed other crimes (simple or qualified theft or rape), all of them institutionalized by court order in La Plata city, Buenos Aires, Argentina. In both groups were evaluated sociodemographic, criminological and psychosocial characteristics through ad hoc questionnaire, as well as psychiatric clinical variables through the MINI (Mini International Neuropsychiatric Interview). The results showed that the multiple factors studied were not significantly associated with the condition of being young murderer. The findings aim to sustain that, in this vulnerable population of youth, homicidal behavior depends more on the circumstances than of personal peculiarities. The authors suggest that preventive actions in adolescents with these risk factors could have an effect on criminal behavior in general, as in homicidal behavior in particular.

    The general aim of this study was to assess the possibility of including elements of environmental health education within the curriculum of a school located in a shantytown of Buenos Aires city, Argentina. An environmental health education campaign was designed to introduce school-aged children to the problems posed by the lack of environmental sanitation, by using rodents as indicators of environmental disorder. The methodology implemented consisted of a lecture and two practical activities where the participating children were the evaluators of their neighborhood environment, recording the environmental factors that indicate direct or indirect presence of rodents and carrying out a survey about rodents among their neighbors. To assess the impact of the activities, an anonymous questionnaire was performed with the students before and after the campaign. The results showed that students were able to identify the man-made factors which favor the presence of rodents and were encouraged to propose strategies related to environmental sanitation to reduce rodent proliferation and the transmission of their parasites. This study demonstrated the feasibility of performing environmental health education campaigns in school-aged children by using practical activities to stimulate observation, participation, and comprehensive understanding of the problems posed by urban pests.

Se busca comprender de qué forma estas trabajadoras, en contextos sociales de desigualdad, desarrollan estrategias donde su trabajo es actualizado en la producción de la dinámica familiar e identitaria, y en la elaboración práctica de sus herencias culturales y su “mundo de vida”. En este sentido, se propone discutir y evaluar algunas de las políticas públicas orientadas a la regularización de esta actividad laboral. La investigación que la ha dado origen plantea la existencia de elementos simbólicos y culturales que deben ser tenidos en cuenta a hora de comprender las dificultades que enfrenta el Estado para fortalecer el registro laboral, la informalidad y la falta de derechos sociales que la caracteriza.

Desde una metodología cualitativa, se indagan cuatro fenómenos específicos: las amenazas, los “bondis”, el cyberbullying y los duelos, para lo cual se realizaron veinte entrevistas en profundidad y 3.000 observaciones virtuales de perfiles de la red social Facebook entre 2013 y 2014. Entre los principales resultados, se observa que la mayoría de las expresiones de violencia se enmarcan en una dinámica offline-online. Asimismo, se ofrece evidencia empírica a partir de la cual es posible afirmar que las expresiones de violencia de estos adolescentes se despliegan en torno a la cultura del “aguante”. El artículo se pregunta si en la plataforma icónica del “me gusta” estas expresiones resultan implícitamente funcionales a la red social o si, por el contrario, permiten desplazamientos y reapropiaciones significativas de los usuarios. En definitiva, se abren nuevos interrogantes acerca de la utilización de estas herramientas por parte de adolescentes de sectores populares marginalizados y se propone complejizar los enfoques en torno a estos fenómenos.

    A ground-based DIfferential Absorption Lidar (DIAL) system has been implemented at CEILAP (CITEFA-CONICET) laboratory (34°33'S, 58°30'W), located in the Buenos Aires industrial suburbs. The goal is to perform measurements of the stratospheric ozone layer. Systematic measurements of ozone concentration profiles from ˜18 to ˜35 km altitude are performed since early 1999. Our measurements are carried out in 5 h in average during the night and in cloudless conditions. The DIAL system allows us to calculate directly the ozone profile from the lidar backscattering radiation since it is a self-calibrating technique. The signal processing takes into account the influence of the temperature profile on the ozone cross section. The temperature data are obtained from the radiosondes measurements performed at Ezeiza International Airport (34°30'S, 58°18'W), 27 km from DIAL station. The evolution of the stratospheric ozone profile is studied for different months. Results are compared with the data obtained by different satellites SAGE II, HALOE and GOME. The comparisons between our DIAL system and the satellite measurements show an agreement better than 20% for 20-35 km altitude range.

Tras el golpe de Estado, funcionó en el Hospital Posadas un Centro Clandestino de Detención en el cual se mantenían personas cautivas ilegalmente, en condición de desaparecidas. Así, en el Hospital Posadas convivieron, simultáneamente, las prácticas relativas al cuidado y restauración de la salud y la perpetración de torturas y asesinatos. En este trabajo se analizarán los recuerdos y olvidos de estos hechos entre diversos vecinos que habitaban, en tiempos de la dictadura, en las inmediaciones del Hospital Posadas. Específicamente, se indagará qué experiencias tuvieron con la violencia de Estado, en particular con el sistema de desaparición de personas, y cómo ellas han quedado inscriptas en sus memorias personales. Por último, se analizarán la información que circulaba y los grados de conocimiento que poseían estos vecinos sobre los atributos, naturaleza y responsables de las desapariciones en el hospital mientras éstas se perpetraban.

    Full Text Available Este artículo estudia la identificación de los homosexuales varones como un grupo singular durante la primera década peronista, bajo la figura de los "amorales". A diferencia de principios de siglo XX, donde estaban integrados en el caótico ambiente de la mala vida. Los varones de mediados de siglo que tenían relaciones sexuales con varones comenzaron a ser destacados como una desviación peligrosa del ideal familiarista y heterosexista. Este proceso se explica a través de la masculinización de la clase obrera operada por el peronismo y la aparición contemporánea de los jóvenes como un sector social problemático y peligroso. Se estudia este desarrollo de la intolerancia comenzando en los primeros años '40 hasta llegar a las razzias antihomosexuales de 1954-1955 en las calles, bares y plazas de Buenos Aires. A diferencia de otras interpretaciones que subrayan el carácter ancilar de las batidas policiales, sostenemos que fueron más que una excusa en el combate del peronismo contra el catolicismo, pues se inscribían en tensiones más profundas del orden social, sexual y simbólico de la Argentina de posguerra.

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

    The Monte Hermoso Formation, cropping out at its type locality of Farola Monte Hermoso (Buenos Aires Province), is a classical fossiliferous unit of the South American Neogene, highlighted by the abundance and diversity of its vertebrate remains. However, its biostratigraphy and age have been largely debated, and numerous discrepancies and controversies have been stated. In this regard, the result of the analysis of new materials recovered from the different levels of this formation, following a strict control of stratigraphic provenance, is here reported. As well, the provenance of specimens of previous collections has been evaluated. The studied assemblage consists of Osteichthyes, Amphibia, Reptilia, Aves and Mammalia. These latter are the most numerous and belong to the Didelphimorphia, Polydolopimorphia, Rodentia, Notoungulata, Litopterna and Xenarthra. The recorded taxa suggest no important faunistic variations among the different levels of the Monte Hermoso Formation that would imply significant chronological differences, and hence, justify the recognition of two biostratigraphic units. The analysis of the first and last records as well as the taxa considered as exclusive, does not support the validity of the biozones of Trigodon gaudryi and Neocavia depressidens previously proposed. On this basis, a new scheme for the Monte Hermoso Formation at its type locality is proposed, including a new single biostratigraphic unit. This unit is the Eumysops laeviplicatus Range Zone, which represents the biostratigraphic base for the Montehermosan Stage/Age of the early Pliocene.

    Full Text Available The molluscs Heleobia castellanosae and Ampullaria canaliculata and cichlid fishes were collected from an artificial pond at Tres de Febrero Park (Buenos Aires city, between June 1994 and May 1995. One hundred and eighty of 2,467 H. castellanosae examined were infected with pre-adults of Lobatostoma jungwirthi, 112 of them in concurrent infections with digeneans. L. jungwirthi was significantly more prevalent in larger snails, especially those infected with larval digeneans, but the prevalence of infection did not fluctuate significantly throughout the year. A. canaliculata and cichlids smaller than 10 cm were not infected, but larger Cichlasoma facetum harboured adults of L. jungwirthi in their intestines. Experimental infections of C. facetum and Gymnogeophagus meridionalis with pre-adult aspidogastreans obtained from H. castellanosae were successful. The development of L. jungwirthi in the snail host involves five arbitrary growth phases. Its life-cycle is heteroxenous, similar to that described for L. manteri, with H. castellanosae as the intermediate host and cichlid fishes as the definitive host in this pond.

    Full Text Available Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed.

This article analyzes the impact of this reform -and others beyond the ecclesiastical sphere- on the rural parishes of Buenos Aires. Here we show that the budget allocated to the Church, one of the main innovations of this reform, hardly modified the income of parish priests.

    Full Text Available In unequal societies, differences in access and quality of early child education and care services determine children´s opportunities. Considering that Argentina is not alien to this phenomenon, this article asks if the way in which child care is socially organized in the City of Buenos Aires operates as a mechanism of social stratification. To answer this question the article parts of a methodological strategy that combines descriptive statistics –means tests and simple comparison of means using per capita income per family and type of early child education and care services that children attend– and inferential statistic, through the application of a logistic regression model that allows to establish statistical significance in the correlation between attendance to early child education and care services and family income, and to ponderate the probability of attendance to these establishments according to the family income level.Overall, this article aims to contribute to the discussion about social stratification and segmentation prevalent in public services, such as child education and care services, in the region.

    Shiga toxin-producing Escherichia coli (STEC) infections are the leading cause of hemolytic uremic syndrome (HUS). STEC is the most common cause of acute kidney disease, responsible for 20% of renal transplants in Argentina. In 2007, an epidemiological survey was conducted among 883 students from the fifth and sixth years of elementary education in the public schools of San Martin City, Buenos Aires, Argentina. Degree of exposure to the known risk factors previously detected in the region as primary causes of STEC infections was evaluated. Risk factors assessed included consumption of hamburgers, poor personal hygiene, and exposure to various types of drinking and recreational water. The study was designed to evaluate exposure to risk factors for STEC infections among different socioeconomic groups. Ninety-five percent of children surveyed reported consumption of hamburgers. Most of these hamburgers were precooked. Children of high and medium strata attended private swimming-pools, while children from the low stratum attended public pools. Only 30.2% of students washed their hands after going to the toilet and only 43.5% reported hand-washing before eating. Students demonstrated high levels of exposure to identified risk factors for STEC infections. Reduction of these risks will require cultural changes aimed at decreasing morbidity caused by food-borne infections. Institutional framework must provide the necessary resources to implement these changes and emphasize the importance of good personal hygiene. Health education must be implemented to increase food safety awareness of the consumers.

Prevalence of: CT: (10.2%; 95%CI 6,7-15,1); AI: (84.8%; 95% CI 80-89 ), and OC: 11,6% (95%CI 7-16) and OC among patients with good registry: 35.7% (95%CI 24,9-48,1). Eighty two % of patients received a prescription for enalapril. Deficient registry was detected in MR. Interviewees expressed difficulties in accessing treatment, lack of medication and use of alternative circuits to get them. Both, staff and patients were exposed to barriers generated by CAPSs and RP. A low degree of blood pressure control was observed, even with adequate prescription. Multifactorial problems explain several barriers to access and maintain hypertension treatment.

    The aim of this study was to describe the spatial distribution of cervical cancer mortality in the Autonomous City of Buenos Aires during the period 1999-2003 and its relationship to the socioeconomic conditions of the population, as well as to compare the distribution during this period with that of the triennium 2004-2006. This ecological study used electoral districts as the unit of analysis. The selected socioeconomic indicators were educational deficit, lack of health insurance and the Material Deprivation of Households Index (Índice de Privación Material de Hogares), taken from the National Population and Housing Census (Censo Nacional de Población, Hogares y Viviendas) of 2001. The stratification of the city into areas according to these conditions and the analysis of standardized mortality ratios showed an increased risk of dying from cervical cancer associated with worse socioeconomic conditions. The stratification and death risks demonstrated a clear spatial pattern, with the south of the city presenting the highest death risks, and the northern and central areas presenting the lowest risks.

    Full Text Available The molt cycle of the natural population of Palaemonetes argentinus Nobili, 1901 from Los Padres Lagoon, Buenos Aires, Argentina, was studied in relation to age, sex, and environmental factors. A total of 1645 individuals (740 females, 539 males, and 366 juveniles were collected and analyzed between December 1995 and December 1996. The results indicate that the sex ratio (males:females remains around 1:1.4 throughout most of the year. The reproductive period extends from September until February (spring and summer, with maximum sexual activity in October and November. Two cohorts originated in the spring and in the summer were differentiated. Ovigerous females arrest their molt cycle during the intermolt period to restart it after oviposition. The duration of the intermolt period does not differ between adults and juveniles. Since the percentage of premolt individuals represents 60% of the total cycle, it was classified as a diecdysic cycle. Within the studied range of water temperatures, the observed variations in the span of the different stages, indicate that this factor does not alter the molt frequency. Like in the rest of decapods, the intermolt duration of P. argentinus is modified by ovarian maturation.

The goal of this project is minimizing the dose received by patients who undergo diagnostic studies X-rays. The first controls were performed at the Institute of Oncology Angel H. Roffo of C.A.B.A – Buenos Aires. The mammographs used were: the digital FujiFilm Amulet and ther hybrid General Electric (GE) Senographe DMR, out of order. The latter was used to adjust protocols and equipment. Quality controls of mamography equipments were done according to the following IAEA documents: Technical Reports Series (TRS) N° 457, Technical Document (TECDOC) -1517 and IAEA Human Health Series N° 17. Among the checks performed are mentioned: mechanical (visual inspection), compression, compression thickness, mean glandular dose for Mo-Mo 28 kV and Mo-Rh 28 kV, repeatability and linearity, half-value layer, accuracy and repeatability voltage, leakage radiation and focus- tray distance. The Radcal calibrated equipment, used for the measurements was provided by the IAEA as part of the project. They are: reader, chamber for mammography, chamber for leakage, voltage meter and other elements such as aluminum plates. In addition, dosimeters TLDs rods 700 and 200 of the Personal Dosimetry Laboratory - CNEA, and dosimetry films of the Medical University - Personal Dosimetry Laboratory and Radiological Protection - were calibrated in the GE mammograph in Mo-Mo for the incident air kerma values of 2.28, 4.58, 6.38, 9.15, 10.96, 14.71 and 18.34 mGy. For both TLDs dosemeters, the effective energy response has been studied for: 14.4, 15, 15.4, 15.7 y 16.1 kev

En este estudio se analizó a 9 pacientes con NAC por Legionella pneumophila atendidos entre 1997 y 2001 en el Hospital de Clínicas José de San Martín de la Universidad de Buenos Aires. Se registraron datos de antecedentes, enfermedad actual, contactos, exposición laboral, examen físico, pruebas de laboratorio y uso previo de antibióticos, y se tomó en cuenta la presencia de criterios de gravedad. Nueve pacientes presentaron diagnóstico de NAC por Legionella, ninguno refirió antecedentes de viajes recientes; cuatro de ellos debieron ser internados en unidades de cuidado intensivo. Siete pacientes tenían antecedentes de tabaquismo, 4 tenían EPOC y un paciente linfoma no-Hodgkin. Nuestra casuística corrobora la baja especificidad de la clínica y estudios complementarios para predecir esta etiología. El aislamiento de Legionella es dificultoso, la seroconversión permite el diagnóstico retrospectivo y requiere plazos prolongados y el antígeno urinario aporta un diagnóstico inmediato. Cuando la legionelosis aparece en casos aislados, como ocurriría en Argentina, si no se piensa en esta etiología no se llegará al diagnóstico.

La contribución amerindia paterna asociada al sub-haplogrupo Q1a3a fue relativamente baja (6%. La menor proporción de haplotipos amerindios y el elevado número de linajes maternos (44% de ese origen, revela que ha habido un aporte diferencial por género en la historia de mestizaje de esa población. Se observó un único perfil E1b1a, el cual es predominante en  África subsahariana. Estos datos, conjuntamente con la información histórica y demográfica, nos permite afirmar que el bajo aporte amerindio y subsahariano observado en  la muestra del AMBA, sería el resultado de las migraciones recientes, iniciadas a mediados del siglo XX, principalmente desde el norte de Argentina y de países limítrofes de elevada composición nativa y, en menor medida, africana.

    Full Text Available In Buenos Aires the “otherness” of Peruvian immigrants is structured around manifestations of discrimination that come from the host society. Our purpose is to analyze immigrant foods and the representations they evoke, as well as to investigate the way in which their cooking acquires new meanings in new contexts, showing a tendency to become a mark of specificity and a way to resist the hostility of the host society. In order to do this, we focus on Peruvian restaurants and specifically ‘exocuisine’ or eating out, as opposed to ‘endocuisine’ or eating in. By starting with an analysis of meals and commensality practices in the ‘eating-out’ context, we aim to account for the processes of construction-reconstruction of relationships among Peruvians as well as between Peruvians and Argentines when eating in restaurants. Our objective we is to highlight the role that restaurants have been performing among immigrants, exploring the expansion of the Peruvian culinary vocabulary and identifying the changes in the social and cultural functions of food. In addition, following the rise of Peruvian cuisine at international level in recent years, we return to the field after nearly nine years in order to register the new meanings it acquires in the local context and how this influences the dialogue between immigrants and the host society.L'immigration péruvienne à Buenos Aires s'inscrit dans un contexte d'accentuation des discriminations envers les différentes communautés rejetées par l'Etat nation argentin.

    Full Text Available Se estudiaron 91 aislamientos de Pseudomonas aeruginosa resistentes a carbapenemes con el objetivo de conocer la prevalencia de metalo-β-lactamasas y evaluar la habilidad del ensayo de inhibición empleando discos de EDTA (1 µmol en su detección. Se determinó la presencia de carbapenemasas en 10 (11% de los aislamientos recuperados. La sensibilidad a aztreonam en los aislamientos resistentes a ambos carbapenemes resultó un buen predictor de la presencia de estas enzimas. Dichas carbapenemasas correspondieron a la enzima VIM-2 en tres de ellos y a VIM-11 en otros siete. En todos los casos los genes codificantes de estas enzimas se encontraron localizados en integrones de clase 1 seguidos corriente abajo de genes codificantes de enzimas acetilantes de antibióticos aminoglucosídicos. El ensayo de detección fenotípica de metalo-β-lactamasas empleando discos de EDTA mostró un 100% de especificidad y sensibilidad en la detección de estas enzimas en la población de Pseudomonas aeruginosa analizadas.The present study was conducted to estimate the prevalence of metallo-β-lactamases in 91 consecutive carbapenem resistant Pseudomonas aeruginosa isolates, recovered from inpatients at Hospital de Clínicas in Buenos Aires. Both, phenotypic and genotypic methods detected the presence of carbapenemases in 10 (11% isolates, corresponding to VIM-11 in 7/10 and VIM-2 in the others. Codifying genes were all included in class 1 integrons, upstream genes coding for aminoglycoside modifying enzymes. One hundred percent sensitivity and specificity was achieved by the metallo-β-lactamases phenotypic screening method using EDTA (1 µmol disks in the Pseudomonas aeruginosa isolates included in this study. Sensitivity to aztreonam in carbapenem resistant isolates was suspicious of the presence of these enzymes.

    Full Text Available The aim of this study was to assemble data on the summer feeding ecology of the Great Pampa-finch, Embernagra platensis at the Laguna de Guaminí, Buenos Aires, Argentina, and to explore the differences related to the dietary patterns for each sex between winter and summer when possible. The stomach contents of 43 birds were analyzed. The animal fraction was composed of Hymenoptera (45.1%, Coleoptera (32.4%, Lepidoptera (6.0%, Araneae (5% and Orthoptera (3.2%. The application of the index of relative importance (IRI resulted in 1490.4 for Coleoptera, 428.5 for Hymenoptera and 162.5 for Lepidoptera caterpillars. The vegetal fraction consisted of Triticum aestivum (26.9%, Cyperaceous (25%, Poaceae (Gramineae (19.3% and Panicum sp. (11.2%. The IRI values were 893.8 for Triticum aestivum, 174.5 for Gramineae, 126.5 for Panicum sp. and 112.8 for Scirpus sp. The food niche width was 0.33 for both sexes; the diversity index resulted in 1.06 for females and 1.33 for males and specific diversity ranged from 1.87 to 2.84. A canonical component analysis (CCA was performed on environmental and morphometric variables, and a Monte Carlo test confirmed the canonical correlations. A t-test showed that some birds harmonized with a logarithmic model and some with a geometric curve. During the summer, Embernagra platensis ingests Hymenoptera and Coleoptera more often than seeds, suggesting that two biological mechanisms could be taking place in this bird.O objetivo deste estudo foi reunir dados referentes à ecologia alimentar do Sabiá-do-banhado, Embernagra platensis, na laguna de Guaminí, Buenos Aires, Argentina, e explorar as diferenças relacionadas aos padrões dietéticos para cada sexo entre inverno e verão, quando possível.

    Full Text Available Como muchas ciudades latinoamericanas, Buenos Aires, durante la década de 1990, fue escenario de una serie de cambios vertiginosos que se asociaron, con mayor o menor énfasis, al imperativo de entrar en un escenario global. Zonas que décadas atrás eran orgullo de la metrópolis y donde el auge constructor del siglo XIX había afincado el poderío de un Estado-Nación en crecimiento comenzaron a ser abandonadas en favor de barrios nuevos o reciclados que insinuaban una impronta estética y cultural. El neoliberalismo imprimió de esta manera sus signos en la ciudad: se produjo la formación, mpulsada por el Estado, de nuevos barrios (como Puerto Madero, el reciclaje de otros con una activa vida previa y en manos de emprendimientos privados (el barrio porteño de Palermo, el surgimiento de shoppings basados en la reconversión de antiguas estructuras industriales abandonadas, entre otros ejemplos. Después de la gran crisis argentina del año 2001, estos procesos fueron inscriptos en una oposición que sugería una ruptura entre la década neoliberal de los noventa y la década siguiente. Este artículo sostiene, por el contrario, que existe una continuidad cultural entre ambas décadas y que esa continuidad se expresa en la perpetuación y potenciación de espacios denominados "globales" y en las prácticas de consumo cultural que los caracterizan. As many cities in Latin America, during the 1990s Buenos Aires City was the scene of various dizzyng changes associated, with greater or lesser emphasis, to the imperative of entering on a global stage. Some areas that decades ago were the reason of the metropolis' pride, and where the nineteenth century, through the urban boom, had installed a symbol of the power of the emerging nation-state, began to be abandoned in favor of new or recycled neighborhoods that revealed an aesthetic or cultural mark.

    Full Text Available A violência se constitui em um dos problemas mais graves da América Latina. O uso de pequenas e leves armas de fogo é considerada a principal responsável por este fato. O objetivo do presente trabalho foi descobrir, a partir de dados do setor saúde, da justiça e da polícia, o número de mortes e crimes envolvendo armas de fogo ocorridos na cidade de Buenos Aires em 2002. Os dados sobre mortalidade e crimes foram obtidos dos Sistemas Nacionais de Estatísticas Vitais e Informação Criminal e os dados sobre apreensão de armas de fogo foram disponibilizados pela Polícia Federal. Utilizaram-se também dados de uma investigação anterior realizada por meio de entrevistas domiciliares a respeito de vitimização por armas de fogo. Durante o período ocorreram 1.304 mortes violentas, dos quais 23.7% corresponderam a mortes provocadas por armas de fogo. Dos 171 indiciamentos policiais por homicídio doloso, 60% haviam sido cometidos com armas de fogo. Das 2.108 pessoas entrevistadas, 6,7% haviam sido vítimas de um crime cometido com arma de fogo. Foram apreendidas 1.887 armas de fogo. A taxa de eventos violentos registrados foi maior nas delegacias da zona sudoeste da cidade, que se caracteriza por condições de vida mais precárias. O impacto da violência e sua relação com armas de fogo constitui-se em um tema relevante da agenda pública.

    The activity concentrations of both natural ({sup 238}U and {sup 232}Th chains and {sup 40}K) and anthropogenic ({sup 137}Cs) radionuclides down along the soil profile have been determined in soil samples collected from inland and coastal areas of the La Plata River, located in the Northeastern region of the Province of Buenos Aires, Argentina. These studies were complemented with {sup 57}Fe Moessbauer spectroscopy characterization, pH, texture and organic carbon content measurements. From Moessbauer results, the sample compositions differ from one area to the other. Spectra from both soil samples are dominated by the Fe{sup 3+ } paramagnetic signal. For soil samples from the coastal area, the {alpha}-Fe{sub 2}O{sub 3} contribution is lower, Fe{sub 3}O{sub 4} was not detected, and the relative areas of each spectral contribution are nearly constant with depth. For samples from the inland area, the Fe{sup 3+ } paramagnetic fraction increases up to 82%, mainly at the expense of the magnetically ordered phase. The main observed activity originates from the decay of {sup 40}K (540-750 Bq/kg), followed by {sup 238}U (60-92 Bq/kg) and {sup 232}Th (37-46 Bq/kg) chains. The activity of {sup 235}U was in all the cases lower than the detection limit (L{sub D} = 0.02 Bq/kg). The only determined anthropogenic nuclide was {sup 137}Cs, arising from the fallout of the Southern Hemisphere nuclear weapon tests. Three of the observed differences in the depth distributions can be described by the dispersion-convection model. A correlation between the natural nuclide activities and the Moessbauer relative fractions was found, whereas no correlation was found between the {sup 137}Cs profile and the relative fraction of Fe{sub 3}O{sub 4} or with other iron species.

El estudio, de diseño transversal, se llevó a cabo durante julio de 1992 en un barrio del Gran Buenos Aires en el que viven unos 9 500 habitantes y una población canina de unos 2 000 animales. Se estudió una muestra aleatoria de 223 perros, de cada uno de los cuales se obtuvo una muestra de sangre. La ficha epidemiológica del animal se obtuvo por encuesta al ama de casa. Las determinaciones serológicas se realizaron por microaglutinación frente a 10 serotipos de Leptospira interrogans. Se halló seropositividad en 57% de los 223 perros examinados; 82% de los sueros positivos coaglutinaron con dos o más serotipos. Los serotipos detectados con mayor frecuencia fueron canicola y pyrogenes. La seroprevalencia en hembras fue menor que en machos (P <0,05 y entre los cachorros de menos de 1 año de edad, menor que en los animales de mayor edad (P <0,01. El callejeo del perro y la presencia de agua estancada frente a la vivienda del propietario fueron los factores de riesgo más importantes entre los que se estudiaron. Las asociaciones de la seropositividad con el contacto con un basural, con el comportamiento de caza del perro y con la presencia de roedores en la vivienda no fueron estadísticamente significativas. Se discuten distintas medidas de control.

    Hand hygiene is a cost-effective measure to reduce microbial transmission (Teare EL, Cookson B, French GL, et al. UK handwashing initiative. J Hosp Infect. 1999;43:1-3.) and is considered to be the most important measure to prevent healthcare-associated infections (Pittet D, Allegranzi B, Sax H, Evidence-based model for hand transmission during patient care and the role of improved practices. Lancet Infect Dis 2006;6:641-52). Unfortunately, the compliance rate of healthcare workers (HCWs) with recommended hand hygiene procedures is less than expected. In order to estimate the effect of a multimodal intervention on improving healthcare workers' compliance with hand hygiene in eleven intensive care units (ICUs) from 11 hospitals of Buenos Aires, a randomized cluster-stepped wedge trial was designed. A multimodal intervention was designed based on practices characterized by being evidence-based, low cost and suggested by qualitative research: (i) leadership commitment, (ii) surveillance of materials needed to comply with hand hygiene and alcohol consumption, (iii) utilization of reminders, (iv) a storyboard of the project and (v) feedback (hand hygiene compliance rate). The study enrolled 705 participants, comprising nurses (66.4%), physicians (25.8%) and other HCW (7.8%) along 9 months of observation. Compliance with hand hygiene in the control group was 66.0% (2354/3565) vs. 75.6% (5190/6864) in the intervention group. Univariate analysis showed an association between the intervention and hand hygiene compliance (odds ratio, OR 1.17; 95% confidence interval (CI), 1.13-1.22). The effect was still present after adjustment by calendar's time and providers' characteristics-age, gender and profession (OR 1.08; 95% CI, 1.03-1.14). His study supports that a multimodal intervention was effective to improve compliance with hand hygiene in ICUs. © The Author 2015.

    Full Text Available La equidad en educación es socialmente deseable debido a la relevancia de la formación en el desarrollo de las personas. Por ello, resulta interesante estudiar si la asignación del gasto destinado a educación tiene en cuenta este aspecto. Dado que el concepto de equidad no es un unívoco, es necesario definir una postura; en el trabajo se asume que existe equidad educativa si hay igualdad en los resultados educativos. Así, el objetivo de éste es analizar si la distribución del gasto educativo entre los distritos de la provincia de Buenos Aires, Argentina, es equitativa. Se planteó la hipótesis de que no lo es. Para contrastarla, se utilizó el coeficiente de GINI y una regresión de Mínimos Cuadrados Ordinarios (MCO. Se halló que la distribución de los fondos se vincula en forma directa con el grado de analfabetismo de los distritos, pero al mismo tiempo se encontró evidencia de que es independiente de la pobreza, de la tasa de abandono escolar, del porcentaje de matrícula en los niveles iniciales y de la proporción de establecimientos clasificados como desfavorables. Entonces, se concluye que la distribución de los fondos de gastos educativos no se rige, o lo hace muy débilmente, por el principio de equidad considerado en el trabajo. Es decir, que la evidencia empírica verifica la hipótesis propuesta.

    Urinary tract infections are a frequent ailment in patients in intensive care units. Candida and other yeasts cause 5-12% of these infections. The value of the finding of any yeast is controversial, and there is no consensus about which parameters are adequate for differentiating urinary infections from colonization or contamination. To analyse the epidemiological characteristics of patients with funguria, to determine potential cut-off points in cultures (to distinguish an infection from other conditions), to identify the prevalent yeast species, and to determine the value of a second urine sample. A multicentre study was conducted in intensive care units of 14 hospitals in the Buenos Aires City Mycology Network. The first and second samples of urine from every patient were cultured. The presence of white cells and yeasts in direct examination, colony counts, and the identification of the isolated species, were evaluated. Yeasts grew in 12.2% of the samples. There was no statistical correlation between the number of white cells and the fungal colony-forming units. Eighty five percent of the patients had indwelling catheters. Funguria was not prevalent in women or in patients over the age of 65. Candida albicans, followed by Candida tropicalis, were the most frequently isolated yeasts. Candida parapsilosis and Candida glabrata appeared less frequently. The same species were isolated in 70% of second samples, and in 23% of the cases the second culture was negative. It was not possible to determine a useful cut-off point for colony counts to help in the diagnosis of urinary infections. As in other publications, C. albicans, followed by C. tropicalis, were the most prevalent species. Copyright © 2015 Asociación Española de Micología. Published by Elsevier Espana.

    The advances of knowledge in molecular and cell biology, biochemistry, medicine and pharmacology that has taken place in the last 60 years in really outstanding and the application of radioisotope techniques in these fields has contributed significantly to them. The research on metabolisms, biodistribution of pharmaceuticals, pharmacodynamics, etc., is mostly carried out by means of techniques employing radioactive materials. Radioisotopes and radiation are frequently used in medicine both as diagnostic and therapeutic tools. Thus, in Nuclear Medicine, many diagnostic procedures are done with radiopharmaceuticals; their production and control are sometimes the responsibility of biochemist. Also, radiometric assays are today a routine method to determine many hormones in endocrinology and in clinical medicine. Receptor determination and characterization is a steadily growing methodology used in clinical biochemistry, pharmacology and medicine. Therefore, this is consider of great importance to teach radioisotopes methodology at the undergraduate and postgraduate level in medicine and biomedicine and give to the future professionals, graduates and technicians, an adequate knowledge of this current tool. At the same time it is necessary to harmonize the use of radioisotope methodologies with the environment preservation. At present, the School of Pharmacy and Biochemistry of the University of Buenos Aires offers four different Courses on Methodology of Radioisotopes in which the Radiological Protection is focused on under different aspects: 1) A Course for students at the undergraduate level, in the Biochemistry Cycle; 2) A Course for post-Graduates in Medicine, Biochemistry, Biology, Chemists or other related disciplines to the health; 3) Another one for professionals wishing to up-date their skills; and finally, 4) A Course for Technicians in Nuclear Medicine and/or Biomedicine

    Full Text Available En este artículo se examinarán las transformaciones espaciales operadas en el Hospital Posadas y sus barrios adyacentes durante el ciclo de violencia política y dictadura militar en Argentina y su inscripción en las memorias de sus trabajadores y habitantes. El Hospital Posadas, ubicado en la localidad de Haedo, en la provincia de Buenos Aires, fue epicentro de un proceso de radicalización política hasta el golpe de Estado de 1976. Tras el golpe, funcionó en sus dependencias un centro clandestino de detención donde estuvieron personas cautivas en condición de desaparecidas mientras se seguían desarrollando las prácticas habituales relativas al centro de salud. Simultáneamente, en sus barrios adyacentes se desenvolvió una intensa represión política. Se considera aquí que el espacio constituye uno de los marcos sociales fundamentales de la memoria colectiva y que en sus permanencias y transformaciones se materializan, a la vez, las memorias sociales de los actores que luchan por dotar de sentido el pasado. Se entiende que, por ello, este análisis permitirá historizar y comprender el proceso de violencia política en la zona a partir de los cambios operados en la topografía del Hospital y del barrio y de su impacto en las memorias de sus trabajadores y habitantes.

    The Upper Pleistocene-Holocene geological evolution, which is characterized by its landscape-forming energy and is related to geological and geomorphological complexity, has an impact on the groundwater dynamics of coastal aquifers. The geological configuration of a sector of the east coast of the Province of Buenos Aires was analyzed, as well as its connection with the geological and geomorphological history of the region during the Late Pleistocene and Holocene, and its influence on the regional and local geohydrological behaviour. This analysis was based on the application of the concept of hydrofacies. Boreholes were drilled and sampled (with depths of up to 40 m), and vertical electrical sounding, electrical tomography and pumping tests were undertaken. The description of the cutting samples by means of a stereo microscope, the interpretation of satellite images, and the construction of lithological and hydrogeological profiles and flow charts were carried out in the laboratory, and then integrated in a GIS. The identification of the lithological units and their distribution in the area allowed the construction of an evolutionary geological model for the Late Pleistocene and Holocene. Three aquifer units can be recognized: one of Late Pleistocene age (hydrofacies E) and the other two of Holocene age (hydrofacies A and C); their hydraulic connection depends on the occurrence and thickness variation of the aquitard units (hydrofacies B and D). The approach adopted allows the examination of the possibilities for groundwater exploitation and constitutes an applied conceptual framework to be taken into consideration when developing conceptual and numerical models at the local and regional scales.

    Full Text Available In order to determine the prevalence and risk factors for shedding of Cryptosporidium spp. in dairy calves, a cross-sectional study was carried out in the northeastern region of Buenos Aires Province, Argentina. Fecal samples from a total of 552 calves from 27 dairy herds were collected, along with a questionnaire about management factors. Cryptosporidium spp. oocysts were detected by light microscopy using Kinyoun staining. Putative risk factors were tested for association using generalized linear mixed models (GLMMs. Oocyst shedding calves were found in 67% (CI95% = 49–84 of herds (corresponding to a true herd prevalence of 98% and 16% (CI95% = 13–19 of calves (corresponding to a true calve prevalence of 8%. Within-herd prevalence ranged from 0 to 60%, with a median of 8%. Cryptosporidium spp. excretion was not associated with the type of liquid diet, gender, time the calf stayed with the dam after birth, use of antibiotics, blood presence in feces, and calving season. However, important highly significant risk factors of oocyst shedding of calves was an age of less or equal than 20 days (OR = 7.4; 95% CI95% = 3–16; P < 0.0001 and occurrence of diarrhea (OR = 5.5; 95% CI95% = 2–11; P < 0.0001. The observed association with young age strongly suggests an early exposure of neonatal calves to Cryptosporidium spp. oocysts in maternity pens and/or an age-related susceptibility. Association with diarrhea suggests that Cryptosporidium spp. is an important enteropathogen primarily responsible for the cause of the observed diarrheal syndrome. Results demonstrate that Cryptosporidium spp. infection is widespread in the study region. Monitoring and control of this parasitic protozoan infection in dairy herds is recommended.

    In order to analyze the interrelationships between free erythrocyte protoporphyrins and the usual iron intake in adult students, biochemical, and hematological values, and dietary daily intake, obtained using the recall method during seven days, were studied. Hematocrit (Hto.), hemoglobin (Hb) and free erythrocyte protoporphyrins (FEP) were determined in a group of 145 female university students, healthy according to the standard parameters of the Buenos Aires University Health Department. Mean iron intake was 23.0 +/- 1.5 mg per day, about 44% being provided by animal sources; 74.5% of the population was within the recommended daily intake according to FAO/WHO; only 0.7% of the population did not cover protein requirements while 35% did not cover energy needs. Hto. and Hb were below normal levels in 7.8% of the population when compared with standards according to ICNND. To obtain information about normal values to FEP, expressed as microgram/100 ml red cells (FEP% r.c.) and FEP/Hb ratio, the group of students with adequate intake of energy and proteins who had normal values for Hb and Hto. was selected. This group, including 94 women, had a mean FEP% r.c. of 15.71 +/- 7.26 and a mean FEP/Hb ratio of 0.44 +/- 0.21. There was observed an inverse correlation between FEP% r.c. and FEP/Hb with total iron intake (r = 0.80 and r = 0.78, respectively) and between FEP% r.c. and Hb concentration (r = 0.81). These results confirm the usefulness of the free erythrocyte protoporphyrins determination as a good index of iron stores and usual intake of this population.

    Full Text Available In countries like Argentina, whose economy depends heavily on crop production, the estimation of harvests is an elementary requirement. Besides providing objectivity, the use of remote sensing allows estimating yield in advance. Since the time of maximum leaf area in wheat corresponds with the critical period of the crop, a good relationship is expected between the Normalized Difference Vegetation Index (NDVI and yield. The present study was carried out in the North of Buenos Aires province, Argentina. Based on the type of soil, the study area can be divided into two homogeneous subzones: a subzone with lower clay content in the southwest and a subzone with higher clay content in the northeast. Nine growing seasons (2003–2011 were studied. In the first five years, an empirical model was calibrated and validated with field-observed wheat yields and MOD13q1 product-NDVI data, whereas in the other four years, the calibrated model was applied by means of yield maps and by comparing with official yields. The MOD13q1 image corresponding to Julian day 289 showed the best fit between NDVI and yield to estimate wheat yield early. Through yield maps, better weather conditions showed higher yields and higher soil productivity presented a greater proportion of the area occupied by higher yields. At department level, an R2 value of 0.75 was found after relating the estimation of the calibrated empirical model with official yields. The method used allows predicting wheat yield 30 days before harvest. Through yield maps, the NDVI perceived the temporal and spatial variability in the study area.

  10. Monitoring cirrus clouds with lidar in the Southern Hemisphere: A local study over Buenos Aires. 1. Tropopause heights

    2009-03-01

    Cirrus clouds in the upper troposphere and the lower stratosphere have recently drawn much attention due to their important role and impact on the atmospheric radiative balance. Because they are located in the upper troposphere their study requires a high resolution technique not only to detect them but also to characterize their behaviour and evolution. A good dynamic range in lidar backscattering signals is necessary to observe and improve our knowledge of cirrus clouds, and thereof, atmospheric parameters in the troposphere and UT/LS due to their vicinity to the tropopause layer. The lidar system measures, in real time, the evolution of the atmospheric boundary layer, stratospheric aerosols, tropopause height and cirrus clouds evolution. The aim of the work is to present the main properties of cirrus clouds over central Argentina and to monitor tropopause height together with their temporal evolution using a backscatter lidar system located in Buenos Aires (34.6 °S, 58.5 °W). A cirrus clouds detection method was used to analyze a set of 60 diurnal events, during 2001-2005, in order to estimate tropopause height and its temporal evolution, using the top of cirrus clouds present on the upper troposphere as a tropopause tracer. The results derived from lidar show a remarkable good agreement when compared with rawinsonde data, considering values of tropopause height with differences less than or equal to 500 m, depending on the signal to noise ratio of the measurements. Clouds properties analysis reveals the presence of thick cirrus clouds with thickness between 0.5 and 4.2 km, with the top cloud located at the tropopause height.

    The AUSTRAL observing program was started in 2011, performing geodetic and astrometric very long baseline interferometry (VLBI) sessions using the new Australian AuScope VLBI antennas at Hobart, Katherine, and Yarragadee, with contribution from the Warkworth (New Zealand) 12 m and Hartebeesthoek (South Africa) 15 m antennas to make a southern hemisphere array of telescopes with similar design and capability. Designed in the style of the next-generation VLBI system, these small and fast antennas allow for a new way of observing, comprising higher data rates and more observations than the standard observing sessions coordinated by the International VLBI Service for Geodesy and Astrometry (IVS). In this contribution, the continuous development of the AUSTRAL sessions is described, leading to an improvement of the results in terms of baseline length repeatabilities by a factor of two since the start of this program. The focus is on the scheduling strategy and increased number of observations, aspects of automated operation, and data logistics, as well as results of the 151 AUSTRAL sessions performed so far. The high number of the AUSTRAL sessions makes them an important contributor to VLBI end-products, such as the terrestrial and celestial reference frames and Earth orientation parameters. We compare AUSTRAL results with other IVS sessions and discuss their suitability for the determination of baselines, station coordinates, source coordinates, and Earth orientation parameters.

    Full Text Available La Ciudad de Buenos Aires está emplazada sobre el margen sur del estuario del Río de la Plata. Las obras de relleno modificaron totalmente la morfología original del área, desde la época de Rosas (1836 hasta la actualidad. Los cambios antrópicos en la configuración de la línea de costa generaron una gran variedad de problemas de fundación en las estructuras edilicias y obras de infraestructura a causa de la heterogeneidad de la composición de los materiales utilizados para el relleno. Debido al creciente desarrollo urbano de la Ciudad Autónoma de Buenos Aires y el área metropolitana, resulta de sumo interés contar con información de detalle sobre las áreas de relleno en la costa del Río de la Plata. Con la finalidad de evaluar la utilidad de diferentes métodos geofísicos para caracterizar el tipo y distribución espacial de los materiales de relleno y su espesor, en este trabajo se presentan los resultados de un estudio piloto llevado a cabo en Ciudad Universitaria. Se realizaron relevamientos con Georadar (GPR, tomografías de resistividad eléctrica (TER y perfiles magnetométricos. Pudo determinarse que las TERs y los métodos magnéticos son muy útiles para investigar las zonas de relleno, mientras que el método de GPR no sería aplicable a la zona de estudio debido a las características intrínsecas de la misma. A partir de los relevamientos realizados pudieron diferenciarse sectores geográficamente muy cercanos dentro de Ciudad Universitaria que presentarían distintos espesores y tipo de relleno. Estos resultados indican que los métodos geofísicos permitirían caracterizar las zonas de relleno a lo largo de la costa de Buenos Aires y nos alientan a continuar esta línea de trabajo.The coast of Buenos Aires city is located on the southern margin of La Plata river estuary.

    Full Text Available Argentina constituye el segundo mercado eléctrico de América del Sur (100.000 GWh consumidos en 2008, según cifras de la Agencia Internacional de la Energía 2010, después de Brasil. La mayor parte del consumo se concentra en la región metropolitana de Buenos Aires cuyos hogares absorben 40% de la electricidad destinada a fines domésticos y las industrias toman 60% del total. Los altos niveles de demanda de la metrópolis han justificado históricamente inversiones en proyectos energéticos, algunos locales, otros en sitios alejados. Así Buenos Aires genera e importa electricidad para cubrir sus necesidades mientras se observa que las regiones exportadoras a veces carecen de servicios locales suficientes. En la región del Noreste, donde se localiza la mayor represa del país –la represa binacional de Yacyretá- la tasa de cobertura eléctrica es inferior a la media nacional (siendo ellas de 90% y 95% respectivamente. Existen luego desigualdades en disponibilidad de electricidad a nivel nacional. Esta presentación1 busca mostrar en qué forma Buenos Aires se ha abastecido de electricidad y las implicancias que el desarrollo de ese mercado trae para las regiones exportadoras. En particular se estudia el sistema de producción y distribución de una de las mayores centrales hidroeléctricas y se constatan las dificultades y beneficios que ha encontrado la región del Noreste, en la obra de Yacyretá, ya en términos de abastecimiento, ya en términos socioeconómicos.

    2007-01-01

    Full Text Available En este escrito se analizan las instancias del proceso de transición hacia el Gobierno por Comunas en la Ciudad Autónoma de Buenos Aires, Argentina, con énfasis en el contexto político administrativo y legal, y en las formas que asume la participación mediante la descripción e interpretación de situaciones de interacción cara a cara en dos Comunas de la Ciudad. La división territorial de la Ciudad de Buenos Aires en Comunas, y la descentralización de algunas funciones del Gobierno de la Ciudad en los gobiernos comunales, son parte de los instrumentos y mecanismos de democracia participativa, definidos por la Constitución de la Ciudad de Buenos Aires del año 1996. El análisis nos permite ver que, si bien las Comunas fueron imaginadas como la herramienta más adecuada para concretar nuevas formas de organización democrática, a más de diez años de haberse aprobado dicha Constitución y habiendo superado largamente todos los plazos previstos, quienes componen la clase política han logrado postergar por más de 12 años la puesta en marcha de esta forma innovadora de gobierno local. Además, de distintas maneras han ido imponiendo la misma lógica política que el espíritu de la Constitución se proponía contrarrestar, es decir, se ha impuesto un nivel alto de concentración política en vez de garantizar una participación amplia, directa y no mediada por las estructuras político partidarias.

    2018-03-01

    Full Text Available The estimation of sediment transfer times remains a challenge to our understanding of sediment budgets and the relationships between erosion and climate. Uranium (U and thorium (Th isotope disequilibria offer a means of more robustly constraining sediment transfer times. Here, we present new uranium and thorium disequilibrium data for a series of nested moraines around Lago Buenos Aires in Argentine Patagonia. The glacial chronology for the area is constrained using in situ cosmogenic 10Be analysis of glacial outwash. Sediment transfer times within the periglacial domain were estimated by comparing the deposition ages of moraines to the theoretical age of sediment production, i.e., the comminution age inferred from U disequilibrium data and recoil loss factor estimates. Our data show first that the classical comminution age approach must include weathering processes accounted for by measuring Th disequilibrium. Second, our combined data suggest that the pre-deposition history of the moraine sediments is not negligible, as evidenced by the large disequilibrium of the youngest moraines despite the equilibrium of the corresponding glacial flour. Monte Carlo simulations suggest that weathering was more intense before the deposition of the moraines and that the transfer time of the fine sediments to the moraines was on the order of 100–200 kyr. Long transfer times could result from a combination of long sediment residence times in the proglacial lake (recurrence time of a glacial cycle and the remobilization of sediments from moraines deposited during previous glacial cycles. 10Be data suggest that some glacial cycles are absent from the preserved moraine record (seemingly every second cycle, supporting a model of reworking moraines and/or fluctuations in the extent of glacial advances. The chronological pattern is consistent with the U–Th disequilibrium data and the 100–200 kyr transfer time. This long transfer time raises the

    Full Text Available En paralelo con la agitación política que irrumpió en Buenos Aires tras la Revolución de 1810, la ciudad experimentó otra forma de conflictividad –a veces vinculada con aquella-: los robos, un fenómeno constante en las dos décadas que sucedieron a Mayo. Generalmente se los ha estudiado junto a otros delitos de la época para evaluar las pautas de criminalidad y control social. En este artículo se los analiza por sí mismos, poniendo el foco en sus causas económicas y en la influencia de la coyuntura política. Los ladrones provenían casi exclusivamente de los sectores subalternos de la sociedad porteña, la llamada plebe urbana, puesto que robar era una de las formas de complementar recursos o conseguir un ingreso, evitando los momentos de desocupación de una estructura laboral frágil y en buena medida estacional. Los bienes robados se volcaban a redes de comercio ilegal: se le vendían a pulperos y tenderos que se beneficiaban de precios más bajos por su adquisición y ofrecían luego esas mercancías en su actividad diaria. En este artículo se rastrean también las características de ese “otro” comercio, sólo parcialmente observable a través de la documentación judicial y policial, que ocupaba un lugar marginal pero destacado en la economía porteña de los años posrevolucionarios. Por último se examinan la organización y el funcionamiento de las gavillas (bandas de ladrones urbanos y se reconstruye la biografía de Manuel Recabarren, el bandido más famoso del período.

    Full Text Available Las patologías podales del bovino son multicausales; entre ellas se cuentan altos niveles de producción y estrés, así como etiologías ambientales, nutricionales, infecciosas, genéticas, razas, estado fisiológico y comportamiento, tanto animal como humano. Están adquiriendo gran importancia debido a la intensificación de la producción. El objetivo del presente trabajo fue determinar la prevalencia de enfermedades podales en explotaciones lecheras y en feedlot, así como comparar ambos sistemas de explotación en la región de Tandil, Buenos Aires, Argentina. A tal fin, se evaluaron 24 tambos en 2005 y un feedlot en 2013 en busca de patologías podales. Los animales que presentaron claudicación se separaron del rodeo y se examinaron clínicamente. Se calculó la prevalencia bruta y por patologías de mayor presentación en ambos tipos de explotación y, además, la proporción según miembro afectado. Se estimaron diferencias entre las prevalencias de cada tipo de producción por medio de Chi cuadrado (p < 0,05 y Razón de Prevalencia. La prevalencia en los 12.132 animales lecheros fue de 2,71% y en los 14.500 de feedlot de 0,57% (Razón de Prevalencia = 4,73; IC 95% = 3,72 a 6,02. La prevalencia de traumatismos en feedlot fue del 0,17% y en los tambos de 0,016% (p < 0,05; la de dermatitis digital fue de 0,69% en los tambos y en feedlot de 0,13% (p < 0,05, mientras la prevalencia de dermatitis interdigital alcanzó 0,81% en los tambos y 0,1% en feedlot (p < 0,05. En ambos sistemas de producción, los miembros más afectados fueron los posteriores (90,4% feedlot y 88,1% tambos. La menor prevalencia de patologías podales en feedlot podría deberse a la baja edad de los animales. No obstante, en los animales de feedlot hay una significativa mayor prevalencia en cuanto traumatismos que en los tambos, mientras que en estos se presentan más casos de dermatitis digital e interdigital.

    To describe the application of the risk and harm reduction model at primary care level to decrease the mortality due to unsafe abortion in the Province of Buenos Aires, Argentina, and evaluate the results. The services offered at primary health units to women undergoing abortion are described-first, only risk reduction and later, legal termination of the pregnancy-including their evolution between 2010 and 2015. The changes in abortion-related maternal mortality are also evaluated. The χ(2) test was used to evaluate the differences in the percentage of abortion-related deaths out of the total number of maternal deaths. Primary care services increased progressively, both for risk reduction and for legal termination of pregnancy, which was carried out successfully, including manual vacuum aspiration, by general physicians and midwives. The proportion of abortion-related maternal deaths with respect to total maternal deaths fell by two-thirds between 2010 and 2014 (P<0.001). The Uruguayan risk reduction model was successfully applied in primary care in the Province of Buenos Aires. Copyright © 2016 International Federation of Gynecology and Obstetrics.

    Full Text Available Resumen La cuenca del río Reconquista es una de las tres grandes cuencas de la Región Metropolitana de Buenos Aires (Argentina gravemente afectada por las inundaciones y por la contaminación. En tanto pieza territorial de la ciudad metropolitana, la cuenca Reconquista fue abordada en los documentos de planificación urbana que se elaboraron para la región durante la segunda mitad del siglo XX: el Plan Regulador de Buenos Aires, el Esquema Director Año 2000, el Estudio del Sistema Metropolitano Bonaerense y el Proyecto 90. Independientemente de que se hayan concretado o no, esas instancias de planificación ilustran las formas de pensar y operar en la cuenca, como un ámbito dentro de la ciudad, como un problema de alcance metropolitano y como una propuesta de transformación territorial, en tres momentos: el de las inundaciones y la hidráulica, el del medio ambiente y la calidad de vida, y el de la ecología y el paisaje, donde cambian las relaciones que se establecen entre la urbanización, el urbanismo y las cuencas hídricas.

    Full Text Available Resumen Los procesos educativos que involucran a los sectores medios- -altos y altos de Buenos Aires son analizados a partir de dinámicas que explican la construcción de un entre-nos: circuitos educativos diferenciados (escuelas secundarias, universidades privadas, circuitos de sociabilidad selectos (clubes sociales y deportivos con "tradición" y "prestigio", elecciones educativas y trayectorias justificadas a partir de una serie de concepciones que nativamente funcionan como "valores" y analíticamente como solidaridades. Comprendemos esa dinámica como un esfuerzo de las instituciones y las familias destinado a reproducir una posición social a partir de una diferencia que se practica en términos morales y se encarna en los cuerpos jóvenes. El trabajo retoma un proceso de investigación etnográfica realizada entre jóvenes y familias de sectores medios altos y altos del Área Metropolitana de Buenos Aires, que busca comprender la reproducción de las posiciones desiguales y la producción de juventud "solidaria" como clave de la diferenciación social

    Full Text Available As cidades de Buenos Aires e do México, desde os primeiros anos do processo de conquista, tinham um sistema de fornecimento de carne com base no monopólio, o estanco, estruturado em torno da figura do obligado, supervisionado pelo Cabildo. Esse sistema irá operar formalmente até meados do século XVIII, quando diversos fatores ocasionaram seu declínio e a necessidade de sua substituição. No caso específico do fornecimento de carne para a cidade de Buenos Aires, destacam-se os estudos de Hernán Asdrúbal Silva e de Juan Carlos Garavaglia. Para a Cidade do México, os trabalhos de Enriqueta Quiroz sobre o estanco são indispensáveis. Neste estudo tentaremos analisar, a partir de uma perspectiva comparativa, esse processo de substituição de um sistema de monopólio para um sistema competitivo, em ambas as cidades, no período colonial.

    Full Text Available The aim of this paper is to quantify one of the characteristics of the production function of the tourism sector in the province of Buenos Aires: the dominant factor content of their touristic resources, one simplified concept which shows the factors of production incorporated in goods. For its estimation and the touristic characterization of the different municipalities of the province, the following elements are used: the inventory of touristic resources of 134 municipalities of the province; their classification into the five categories listed by OEA; and the factor intensity of each category. One interesting result is that most municipalities with high touristic GDP show a dominant factor content of capital, the implication being that comparative advantage in the Province of Buenos Aires in Argentina is based on contemporary technical, scientific and artistic work. It may be concluded that there is place to exploit tourism in Argentina, what points to the need to accompany them with a correct design of public policies.

    Full Text Available Este trabajo aborda los vínculos que gestaron un universo de mestizaje biológico y cultural en la frontera de Buenos Aires durante el siglo XIX. Tiene por objeto realizar una indagación del mestizaje observado, por un lado, desde las mujeres indias y sus relaciones sexuales y amorosas con hombres hispano-criollos, y por otro, desde el parentesco simbólico. Este abordaje de la familia y el parentesco pretende iluminar desde un ángulo diferente las relaciones entre infieles y cristianos, que hasta ahora han sido analizadas a través del comercio, los tratados y la violencia expresada en malones o en intervención de fuerza militar hispano-criolla en territorio indio.This paper studies sexual and marital practices of Indian women and Hispanic/ Creole men in the frontier of Buenos Aires in the 19th century. It explores the creation of a Métis culture through the analysis of family, kinship and god-parenthood ties seeking to illuminate from a different angle the relationship between heathens and Christians which has been mostly studied from the standpoint of commerce, treaties and war.

    Full Text Available En las últimas décadas el sector salud sufrió en la provincia de Buenos Aires un agudo proceso de descentralización de servicios hacia los municipios. El mismo, no estuvo acompañado por la definición de un modelo prestacional que instituyera los niveles a ser garantizados por cada una de las unidades territoriales menores. Este trabajo pone el foco en las consecuencias que han tenido en la política local los criterios de distribución de los fondos de coparticipación en "salud" desde el Estado provincial hacia los municipios. Interesa comprender cómo estos criterios incentivan, restringen y organizan la política sanitaria local dando lugar a una fragmentación que genera diferentes condiciones de ejercicio del derecho a la salud en cada espacio local. Como parte de un proyecto colectivo más general, el estudio busca reconstruir para los 24 municipios del Gran Buenos Aires las condiciones a nivel macro en que se desenvuelve la política local para detectar la existencia de "patrones típicos" frente a la crisis del año 2001, que permitan explicar la orientación de las estrategias locales.

    Since 2007, more than half of the world's population live in urban areas. Urban atmospheres are dominated by pollutants associated with vehicular emissions. Transport emissions are an important source of non-methane volatile organic compounds (NMVOCs) emissions, species of high interest because of their negative health effects and their contribution to the formation of secondary pollutants responsible for photochemical smog. NMVOCs emissions are generally not very well represented in emission inventories and their speciation presents a high level of uncertainty. In general, emissions from South American countries are still quite unknown for the international community, and usually present a high degree of uncertainty due to the lack of available data to compile emission inventories. Within the Inter-American Institute for Global Change Research (IAI, www.iai.int) projects, UMESAM (Urban Mobile Emissions in South American Megacities) and SAEMC (South American Emissions, Megacities and Climate, http://saemc.cmm.uchile.cl/), the effort was made to compute on-road transport emission inventories for South American megacities, namely Bogota, Buenos Aires, Lima, Sao Paulo and Santiago de Chile, considering megacities as urban agglomerations with more than 5 million inhabitants. The present work is a continuation of these projects, with the aim to extend the calculated NMVOCs emissions inventory into the individual species required by CTMs. The on-road mobile sector of the metropolitan area of Buenos Aires (MABA), Argentina, accounted for 70 Gg of NMVOCs emissions for 2006, without considering two-wheelers. Gasoline light-duty vehicles were responsible for 64% of NMVOCs emissions, followed by compressed natural gas (CNG) light-duty vehicles (22%), diesel heavy-duty vehicles (11%) and diesel light-duty vehicles (7%). NMVOCs emissions were speciated according to fuel and technology, employing the European COPERT (Ntziachristos & Samaras, 2000) VOCs speciation scheme for

    Full Text Available OBJETIVOS: Evaluar cómo responden los estafilococos hospitalarios sensibles y resistentes a la meticilina ante la acción de diferentes antisépticos y desinfectantes empleados habitualmente en los hospitales de la Provincia de Buenos Aires, Argentina. Demostrar la eficacia de esas sustancias mediante la determinación de sus concentraciones bactericidas eficaces, así como analizar si existe correlación entre la resistencia a biocidas y la resistencia a la meticilina en esta población bacteriana. MÉTODOS: Se evaluó la acción de siete biocidas con 25 cepas de estafilococos nosocomiales sensibles y resistentes a la meticilina y una cepa de colección, Staphylococcus aureus ATCC 6538. Las cepas hospitalarias provienen de dos hospitales de máxima complejidad y fueron obtenidas, durante los meses de abril de 2000 a mayo de 2002, de muestras clínicas (hemocultivo, urocultivo, punta de catéter y abceso pertenecientes a pacientes de ambos sexos, internados y ambulatorios. Después del aislamiento de dichas cepas, determinamos la sensibilidad a antibióticos mediante el método de difusión en agar de Kirby y Bauer. Para estudiar la acción de los biocidas de uso hospitalario sobre estas cepas, empleamos el ensayo de Kelsey-Sykes, que permite establecer las concentraciones bactericidas eficaces de tales compuestos. RESULTADOS: Los resultados muestran que la respuesta de las cepas hospitalarias resistentes y sensibles a la meticilina varía con respecto a la cepa de colección. El digluconato de clorhexidina, la yodopovidona, la tintura de yodo débil y el glutaraldehído alcalino fueron eficaces contra la mayoría de las cepas, independientemente de su resistencia o sensibilidad a los antibióticos. CONCLUSIONES: Estas evaluaciones no indican ninguna asociación entre la resistencia a la meticilina y la resistencia a los biocidas evaluados. Asimismo, apuntan a la necesidad de seguir investigando para valorar la eficacia de los agentes qu

    The advancement of knowledge in physics studies, medicine, pharmacology, cell biology and other disciplines that take place during the last 60 years is principally due to radioisotopes techniques. For this reason, the importance to teach radioisotopes methodologies at undergraduate and postgraduate levels kept growing. At the same time it was necessary to harmonize the use of these methodologies with environmental preservation. The School of Pharmacy and Biochemistry of the University of Buenos Aires offers four different Courses on Methodology of Radioisotopes in which the Radiological Protection is focalized under different aspects: 1) A Course for students in the Biochemistry Cycle; 2) A Course for post-Graduate in Medicine, Biochemistry, Biology, Chemists or other disciplines related to the health. 3) Another one for professionals wishing to up-date their knowledge; and finally, 4) one for Technicians in Nuclear Medicine and/or Biomedicine. The aims for teaching Radiological Protection are different for the four levels; in 1), the subject was done from 1960, (optional or mandatory) and with a arrived number of students. In some aspects the teaching of radioprotection is formative and in others informative, because the approval of the a signature does not habitable to ask from the Nuclear Regulatory Authority the authorization to work with radioactive material; in 2), the Course begun in 1962 and 1520 professionals have approved it. In this case the training in radioprotection aspects is theoretical and practical and very intensive, encompassing: dosimetric magnitudes and units, internal and external dosimetry of 125 I, 131 I, 201 Tl, 99M Tc, 60 Co and other isotopes, qualification of area, working conditions, contamination barriers, shielding; justification, optimization and dose limits; radioactive wastes; legal aspects; national and international legislation.

    Full Text Available Frequently, college students have issues to learn academic contents included in the subjects of their courses. Such low quality learning is reflected in failures and academic dropout, therefore being matters of concern for teachers and governments. Learning processes in college depend, in part, on the coincidence between teaching methods and students’ learning styles. They are defined as the preference of students when they have to deal with information, particularly the way to perceive it and process it. Learning styles can be trained by the repeated use of specific learning strategies. In such cases, when learning styles coincide with the learning context in order to facilitate the acquisition of new knowledge and its integration with previous information, academic success can be achieved more naturally. To get this match it is required from teachers to adapt their styles and strategies to their students’ learning preferences. Other alternative rests on the design of actions to train students in the use of the appropriate learning styles able to enhance learning. Focused on the second option, the present study aims at: 1 the description of the influence of different learning strategies on each learning style, and 2 the analysis of the way each style explains students’ academic achievement. A transversal, non-experimental, explicative design was employed. 763 college students from Buenos Aires with ages ranging from 17 to 36 years were included in the sample. Locally adapted versions of the Honey-Alonso Questionnaire of Learning Styles -CHAEA as its Spanish acronym-, and Learning and Study Strategies Inventory –LASSI- were used for data gathering. Results showed that the Accommodating style is explained positively and significantly by the Collaborative Learning, Resources for Learning and Information 2.0 Management Competence strategies. Besides, it is observed that the strategies Collaborative Learning, Resources for Learning and
