    Man-made activities exert great influences on fluvial ecosystems, with lowland rivers being substantially modified through agricultural land use and populations. The recent construction of drainage canals in the upper stretch of the Salado-River basin caused the mobilization of huge amounts of salts formerly stored in the groundwater. The main aim of this work was to analyze the effect of the discharges of those canals into the Salado-River water, under different hydrologic conditions, and the role of the wetlands and shallow lakes placed along the canals' system. Physicochemical variables were measured and water samples were taken during times of high water, mean flows, drought, and extreme drought. The environmental variables and the plankton development were related to the hydrologic regime and reached minimum values during floods because of low temperatures and dilution. Local effects on the water's ionic composition became pronounced during droughts because of groundwater input. Nutrient concentrations were mainly associated with point wastewater discharges. Conductivity, ion concentrations, total plankton biomass, and species richness increased in the Salado-River downstream site, after the canals' discharges. The artificial-drainage system definitely promotes the incorporation of salts into the Salado-River basin. In this scenario, a careful hydraulic management is needed to take into account this issue of secondary salinization that threatens the economic exploitation of the region. The wetlands present in this study acted as service environments not only helping to reduce salt, nutrient, and suspended-solid concentrations downstream but also contributing a plethora of species and plankton biomass into the Salado-River main course.

    Full Text Available This article presents an analysis of the commerce that took place at the mouth of the Salado River, which was born from the war with the Brazilian Empire (1825-1828 in an alternate port to the one in the provincial capital of Buenos Aires. By delving into sources that have not been explored much by investigations on this subject, we study the various economic activities that took place in this new port—transportation, freight, import, and export— between 1830 and late 1850. Simultaneously, we examine the problems that the need for control over these activities generated for the authorities.

    This field study assessed water quality of Salado River basin by using a set of biomarkers in the fish Prochilodus lineatus. Multiple biomarkers were measured, including morphological indexes (condition factor, liver somatic index), hematological (red and white blood cells) and biochemical (glucose, total protein and cholinesterase activity) parameters. Besides, detoxication and oxidative stress markers (antioxidant enzymes, lipid peroxidation) were measured in liver, gills and kidney. Despite water quality assessment did not show marked differences among sites, biomarkers responses indicate that fish are living under stressful environmental conditions. According to multivariate analysis glucose, glutathione S-transferase activity, lipid peroxidation levels and the count of white blood cells are key biomarkers to contribute to discrimination of sites. So, we suggest use those biomarkers in future monitoring of freshwater aquatic systems. - A battery of biomarkers was successfully applied to assess the health of the fish Prochilodus lineatus from Salado River basin.

    The Upper Seven Rivers and Salado Formations contain the uppermost salts within the interior Palo Duro Basin, Stratigraphic and structural evidence based on geophysical well logs indicate that both dissolution and facies change have influenced the thickness of these uppermost salts. The magnitude of vertical salt loss due to dissolution is interminable at this time because original salt thickness is unknown. Gradual thinning of the Upper Seven Rivers Formation is recognized from south to north across the Palo Duro Basin. Anhydrites within the formation pinch out toward the basin margins, indicating that section loss is in part depositionally controlled. Additionally, informal subdivision of the Upper Seven Rivers Formation suggests that salt dissolution has occurred in the uppermost salt. A northeast-trending zone of thin Upper Seven Rivers Formation in portions of Deaf Smith, Randall, Castro, and Parmer Counties is possibly related to Tertiary dissolution. In New Mexico, local thinning of the Upper Seven Rivers Formation may be associated with faulting. Triassic erosion on uplifted fault blocks has affected the Upper Permian section. The Salado salt margin is located within the interior Palo Duro Basin. Geophysical well logs and core evidence indicate that the salt margin has migrated basinward as a result of dissolution. Permian dissolution probably contributed to some salt loss. 106 refs., 31 figs., 2 tabs

    The Quequén Salado river basin has been the focus of several contributions since the first decades of the XX century, namely dealing with the general geological features of the deposits and with the vertebrate remains. In this paper, the Neogene geological history documented by the Quequén Salado river exposures is reconstructed by means of stratigraphic, sedimentological and paleomagnetic studies along with the paleontological analysis of vertebrate remains. The study area is a crucial setting not only to better understand the evolution of the southern Pampas basin during the late Miocene-early Pliocene interval, but also to test the validity of the biochronologic and biostratigraphic schemes, especially the "Irenense". A geological model for the Quequén Salado river valley is proposed: a case of downcutting and headward erosion that contributes with a coherent interpretation to explain the spatial distribution of facies and fossil taxa: the younger in the distal sector of the Quequén Salado middle basin and the older in the lower basin. The sedimentary record is believed to represent the distal reaches of a distributary fluvial system that drained from the Ventania ranges. The stratigraphic section of Paso del Indio Rico results a key stratigraphic site to fully understand the stratigraphic nature of the boundary between the Miocene and the Pliocene (the Huayquerian and Montehermosan stages/ages). In this sense, two stratigraphically superposed range zones have been recognized in the area: Xenodontomys ellipticus Range Zone (latest Miocene-early Pliocene; late Huayquerian), and Eumysops laeviplicatus Range Zone (early Pliocene; Montehermosan). Taking into account the available geological and paleontological evidences, the "Irenense" would not represent a valid biostratigraphic unit, since, according to the geological model here proposed, it would be represented by elements of the Xenodontomys ellipticus Range Zone in the lower QS basin and by elements of the

    In March 2015, the Salado watershed in the Atacama Desert was affected by unusual storms that unleashed floods never recorded before in northern Chile. Chañaral, an urban center located at the mouth of the Salado River, suffered the most catastrophic consequences on the population and infrastructure. Several natural and anthropic factors contributed to the magnitude and effects observed in this event. The total precipitation, of more than 80 mm in the upper section of the basin, produced a massive and rapid hyperconcentrated flow from the Andean foothills, which propagated along the channel with high velocities, depositing more than 2 m of mud in Chañaral. The dynamics of the flood in the city was also influenced by mine tailings deposited at the river mouth. The mining industry in this region during the previous century deposited approximately 200 million tons of mine tailings in the Chañaral Bay. The accumulation of this legacy mining deposits at the river mouth changed the local morphodynamics, which exacerbated the impacts of the flood. The objective of this work is to improve our understanding of the factors that affect the hydrodynamic of floods in hyper-arid regions. We perform numerical simulations using data collected in the field to reconstruct the event of March 2015 in Chañaral, integrating hydrological and hydrodynamic models to propagate the hydrograph in the city with high resolution. By using the reconstruction of the hydrograph and peak flow estimated by Wilcox et al., 2016, we simulate the flood using a two-dimensional model of the shallow-water equations, fully coupled with the sediment concentration (Contreras & Escauriaza, 2016). To identify the influence of the tailing deposits on the flow hydrodynamics, we use high-resolution data of the pre- and post-disaster topography. We compare the performance of different methodologies to assess the destructive power of the flood, considering also the influence of the sediment concentration in the

    Full Text Available The contributions of nutrients and xenobiotics by anthropogenic activities developed in riverside deteriorate water quality. In this context, the impact of different agroindustry effluents on the water quality of Salado River in Buenos Aires Province (Argentina was analyzed applying water quality indexes (WQI. Water quality index is an efficient a simple monitoring tool to instrument corrective and remediation policies. Winter and summer samplings were performed. A minimal water quality index (WQImin was calculated using only two parameters which can be easy determined in situ. The use of WQImin may be a useful methodology for river management. Meat industry appears as the most pollutant source. Since it is considered as point pollution source, effluents should be treated previous to its disposal with the available technologies.

    Full Text Available El presente trabajo está centrado en el estudio de la calidad de agua de los cursos que integran la cuenca hidrográfica del río Quequén Salado, Argentina, con el objeto de evaluar su empleo para riego suplementario. Se realizaron determinaciones de salinidad y sodicidad en muestras de agua tomadas en distintos tramos de los ríos y arroyos de la cuenca, así como en las lagunas más importantes, durante la primavera y el verano de los años 1998, 1999 y 2000. El estudio se cumplimentó con la caracterización química de los principales cursos. En base a los valores de conductividad eléctrica y RAS obtenidos, se cartografiaron aquellos sectores de la cuenca con calidades de riego similares. De acuerdo a estos resultados se establecieron los tipos de cultivo que podrían regarse teniendo en cuenta el grado de tolerancia de cada uno. Las aguas de los arroyos provenientes del sector de sierra son de muy buena calidad, y no presentan restricciones para casi ningún tipo de cultivos. Aunque de menor aptitud, los cursos de la cuenca media permiten el riego de los principales cultivos de la zona como el trigo, maíz, girasol, soja y sorgo, entre otros. El agua del río Quequén Salado presenta valores de salinidad sólo tolerados por la cebada y algunas pasturas. No obstante, no se recomienda su uso por su elevada sodisidad. Entre los constituyentes secundarios se determinó el contenido de boro, ya que este elemento puede resultar muy tóxico para determinadas especies. No se encontraron concentraciones superiores al límite permisible de 1 mg/ l, pudiéndose mencionar máximos de 0.84 mg/ l en el río Quequén Salado y 0.76 mg/ l en uno de los afluentes principales.

    The Rio Salado River Basin in Argentina is an economically important region that generates 25-30 percent of Argentina's grain and meat production. Between 2000-2011, floods in the basin caused nearly US$4.5 billion in losses and affected 5.5 million people. With the goal of developing cost-efficient flood monitoring and prediction capabilities in the Rio Salado Basin to support decision making, Cloud to Street is developing satellite based analytics to cover information gaps and improve monitoring capacity. This talk will showcase the Flood Risk Dashboard developed by Cloud to Street to support monitoring and decision-making at the level of provincial and national water management agencies in the Rio Salado Watershed. The Dashboard is based on analyzing thousands of MODIS, Landsat, and Sentinel scenes in Google Earth Engine to reconstruct the spatial history of flooding in the basin. The tool, iteratively designed with the end-user, shows a history of floodable areas with specific return times, exposed land uses and population, precipitation hyetographs, and spatial and temporal flood trends in the basin. These trends are used to understand both the impact of past flood mitigation investments (i.e. wetland reconstruction) and identify shifting flood risks. Based on this experience, we will also describe best practices on making remote sensing "flood dashboards" for water agencies.

    WIPP Salado Hydrology Program Data Report number-sign 1 presents hydrologic data collected during permeability tests of the Salado Formation performed from August 1988 through December 1989. Analysis and interpretation of the test data are presented in a separate report. The report presents the results of the drilling and testing of six boreholes drilled from the WIPP underground facility 655 m below ground surface in the Salado Formation. Permeability tests were conducted using multipacker test tools with inflatable packers to isolate borehole intervals to allow formation pore-pressure buildup and subsequent pulse-withdrawal tests. Test data include pressures and temperatures in brine-filled, packer-isolated test intervals and borehole-closure and axial test-tool-movement measurements. Permeability tests were performed after installing multipacker test tools in test boreholes, inflating the packers, and allowing pressures to build up in the isolated intervals. Pulse-withdrawal tests were performed after buildup pressures approached the apparent formation pore pressure. Pulse injections were sometimes performed to increase the fluid pressures in isolated intervals. Compliance tests were conducted in lengths of steel and stainless-steel casing to evaluate the mechanical performance of the multipacker test tools. The stainless-steel compliance-test chamber was installed with externally mounted thermocouples in a downward-angled borehole in Experimental Room 4. Compliance tests included leak tests and simulated pulse-injection and pulse-withdrawal sequences. 9 refs., 143 figs., 2 tabs

    1987-02-01

    The present boundaries of the San Andres, Seven Rivers, and Salado salts generally lie along the periphery of the Palo Duro and Tucumcari Basins. Various geologic mechanisms occurring singularly or in combination determined the positions of the salt margins. These mechanisms include nondeposition of salt and syndepositional and postdepositional dissolution. In New Mexico, San Andres units pinch out against the Pedernal and Sierra Grande Uplifts, indicating that nondeposition established the original salt margins there. Syndepositional dissolution of exposed Upper San Andres salts occurred in response to Guadalupian upwarp of the basin margins. Triassic erosion differentially removed Permian salt-bearing formations along the uplifts. Late Tertiary dissolution is indicated by fill of north-south trending collapse valleys. In Texas, Guadalupian upwarp along the Amarillo Uplift caused pinchout of Units 2 and 3 in the Lower San Andres and influenced the deposition of subsequent salt-bearing strata. The discontinuity of Upper San Andres evaporites across the Amarillo Uplift suggests syndepositional dissolution. Along the eastern and northeastern basin margin, dissolution may have accompanied Triassic erosion of locally uplifted Upper Permian strata. Tertiary dissolution is recognized beneath anomalously thick Ogallala Formation sections that overlie collasped Permian strata. 49 refs., 31 figs., 2 tabs

    This report documents a literature review of methods for measuring relative permeability as applied to low permeability anhydrite rock samples from the Salado Formation. About one hundred papers were reviewed, and four methods were identified as promising techniques for measuring the relative permeability of the Salado anhydrite: (1) the unsteady-state high-rate method, (2) the unsteady-state stationary-liquid method, (3) the unsteady-state centrifuge method, and (4) the unsteady-state low-rate method. Except for the centrifuge method, all have been used for low permeability rocks. The unsteady-state high-rate method is preferred for measuring relative permeability of Salado anhydrite, and the unsteady-state stationary-liquid method could be well suited for measuring gas relative permeability of Salado anhydrite. The unsteady-state low-rate method, which combines capillary pressure effects with relative permeability concepts may also prove effective. Likewise, the unsteady-state centrifuge method may be an efficient means for measuring brine relative permeability for Salado anhydrite, especially at high gas saturations.

    .571 ha eran sitios donde la recurrencia de anegamiento fue >40%, y que el 7,98% de la superficie destinada a verdeos (51.504 ha se realizaron en sitios riesgosos.It is well documented that the lower basin of the Salado River has been always exposed to frequent floods. Nevertheless, from 1986 to 2001 the cultivated surface of the Flooding Pampas increased by 69%, being this agricultural expansion mostly over lands that have been periodically affected by floods. A flooding risk analysis was carried out in order to assist with the planning and disposition of farming activities in the Flooding Pampas. For this purpose, the recurrence of precipitations was calculated over 20 meteorological stations, and linked to a by-pixel flooding frequency layer resultant from an analysis of a time-series of satellite images. Results denote that extreme events of accumulated precipitation have been registered in all seasons, being autumn and winter flooding events more prolonged than the spring and summer ones. Even though autumn and winter had similar flooding durabilities, autumn turned out to be the critical season as a result of a higher frequency of flooding events in April and May. Severe flooding could occur when precipitations exceed 150-200 mm, as precipitation accumulations of these magnitudes were related to flooded areas equivalent to 68.76% of the region (5,844,709 ha. Anthropic structures contributed to as much as 2.11% of the regional flooding, as shown by the flooding pattern of the region, being channels 12, 11 and 9, as well as the provincial highway No. 9 and the train rail from Metrovías the main impediments for the water flow. For the 2003-2004 period, we deter-mined through remote sensing techniques that 22.8% of the surface with crop production (173,571 ha corresponded to areas with a flooding recurrence higher than 40%, whereas only 7.98% of the surface with sown pastures (51,504 ha corresponded to risky areas.

  6. Simulation of regional-scale groundwater flow in the Azul River basin, Buenos Aires Province, Argentina

    Science.gov (United States)

    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. Les résultats du modèle reproduisent convenablement les chroniques de débit des écoulements de surface

    2017-10-01

    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 aim of this study is to analyze the origin and quality of water used for consumption in a sample of households in Matanza-Riachuelo river basin area in Greater Buenos Aires, Argentina. The results of drinking water by source indicated that 9% of water samples from the public water system, 45% of bottled water samples and 80% of well water samples were not safe for drinking due to excess content of coliforms, Escherichia coli or nitrates. Individuals living in households where well water is the main source of drinking water have a 55% higher chance of suffering a water-borne disease; in the cases of diarrheas, the probability is 87% higher and in the case of dermatitis, 160% higher. The water for human consumption in this region should be provided by centralized sources that assure control over the quality of the water.

    2001-01-01

    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

  18. Preliminary report on fluid inclusions from halites in the Castile and lower Salado formations of the Delaware Basin, southeastern New Mexico

    International Nuclear Information System (INIS)

    Stein, C.L.

    1985-09-01

    A suite of samples composed primarily of halite from the upper Castile and lower Salado Formations of the Permian Basin was selected from Waste Isolation Pilot Plant (WIPP) core for a reconnaissance study of fluid inclusions. Volume percent of these trapped fluids averaged 0.7% to 1%. Freezing-point depressions varied widely and appeared to be unrelated to fluid-inclusion type, to sedimentary facies, or to stratigraphic depth. However, because very low freezing points were usually associated with anhydrite, a relation may exist between freezing-point data and lithology. Dissolved sulfate values were constant through the Castile, then decreased markedly with lesser depth in the lower Salado. This trend correlates very well with observed mineralogy and is consistent with an interpretation of the occurrence of secondary polyhalite as a result of gypsum or anhydrite alteration with simultaneous consumption of dissolved sulfate from the coexisting fluids. Together with the abundance and distribution of fluid inclusions in primary or ''hopper'' crystal structures, this evidence suggests that inclusions seen in these halites did not migrate any significant geographical distance since their formation. 28 refs., 17 figs., 2 tabs

    Full Text Available Understanding the relationship between the project of modernity and urbanism has been key to understanding the city of Buenos Aires’ material transformations throughout the 20th century. This paper considers how thinking about the issues of modernity and urbanism from the perspective of monuments--namely, the Obelisk of Buenos Aires--sheds new light on how elements of this modernizing project were undertaken and how its material markers have been used and manipulated, and modified through their representation in cultural discourse on the city. Rethinking Buenos Aires from the Obelisk implies literally thinking from underground, from the subway lines that form its base and transform it into a popular symbol of mobility.

    1995-08-01

    Salado Mass Concrete (SMC) has been developed for use as a seal component in the Waste Isolation Pilot Plant. This concrete is intended to be mixed from pre-bagged materials, have an initial slump of 10 in., and remain pumpable and placeable for two hours after mixing. It is a mass concrete because it will be placed in monoliths large enough that the heat generated during cement hydration has the potential to cause thermal expansion and subsequent cracking, a phenomenon to avoid in the seal system. This report describes effects on concrete properties of changes in ratio of water to cement, batch size, and variations in characteristics of different lots of individual components of the concrete. The research demonstrates that the concrete can be prepared from laboratory-batched or pre-bagged dry materials in batches from 1.5 ft 3 to 5.0 yd 3 , with no chemical admixtures other than the sodium chloride added to improve bonding with the host rock, at a water-to-cement ratio ranging from 0.36 to 0.42. All batches prepared according to established procedures had adequate workability for at least 1.5 hours, and achieved or exceeded the target compressive strength of 4500 psi at 180 days after casting. Portland cement and fly ash from different lots or sources did not have a measurable effect on concrete properties, but variations in a shrinkage-compensating cement used as a component of the concrete did appear to affect workability. A low initial temperature and the water-reducing and set-retarding functions of the salt are critical to meeting target properties

    1997-05-01

    This report documents, demonstrates, evaluates, and provides theoretical justification for methods used to convert experimental data into relative permeability relationships. The report facilities accurate determination of relative permeabilities of anhydride rock samples from the Salado Formation at the Waste Isolation Pilot Plant (WIPP). Relative permeability characteristic curves are necessary for WIPP Performance Assessment (PA) predictions of the potential for flow of waste-generated gas from the repository and brine flow into repository. This report follows Christiansen and Howarth (1995), a comprehensive literature review of methods for measuring relative permeability. It focuses on unsteady-state experiments and describes five methods for obtaining relative permeability relationships from unsteady-state experiments. Unsteady-state experimental methods were recommended for relative permeability measurements of low-permeability anhydrite rock samples form the Salado Formation because these tests produce accurate relative permeability information and take significantly less time to complete than steady-state tests. Five methods for obtaining relative permeability relationships from unsteady-state experiments are described: the Welge method, the Johnson-Bossler-Naumann method, the Jones-Roszelle method, the Ramakrishnan-Cappiello method, and the Hagoort method. A summary, an example of the calculations, and a theoretical justification are provided for each of the five methods. Displacements in porous media are numerically simulated for the calculation examples. The simulated product data were processed using the methods, and the relative permeabilities obtained were compared with those input to the numerical model. A variety of operating conditions were simulated to show sensitivity of production behavior to rock-fluid properties

    Full Text Available Measures of hydrologic connectivity have been used extensively to describe spatial connections in riverine landscapes. Hydrologic fluctuations constitute an important macrofactor that regulates other environmental variables and can explain the distribution and abundance of organisms. We analysed morphological variations among individuals of two freshwater crab species, Zilchiopsis collastinensis and Trichodactylus borellianus, from localities of the middle Paraná River basin during two phases of the local hydrological regime. Specimens were sampled at sites (localities of Paraná River, Saladillo Stream, Salado River and Coronda River when water levels were falling and rising. The conductivity, pH, temperature and geographical coordinates were recorded at each site. The dorsal cephalothorax of each crab was represented using 16 landmarks for Z. collastinensis and 14 landmarks for T. borellianus. The Canonical Variate Analyses showed differences in shape (for both species among the crabs collected from the Paraná and Salado Rivers during the two hydrologic phases. We did not find a general distribution pattern for shape among the crab localities. During falling water, the shapes of Z. collastinensis were not related to latitude-longitude gradient (i.e., showing greater overlap in shape, while during rising water the shapes were ordered along a distributional gradient according to geographical location. Contrary, shapes of T. borellianus were related to latitude-longitude during falling water and were not related to distributional gradient during rising water. The cephalothorax shape showed, in general, no statistically significant covariations with environmental variables for either species. These results show that each freshwater crab species, from different localities of the middle Paraná River, remain connected; however, these connections change throughout the hydrologic regime of the floodplain system. This study was useful for delineating

    Full Text Available This paper is based on an analysis of the land and soil use regulations in the 23 counties of the basin of the rivers Paraná and de la Plata, which make up the area of study of the project in which this is framed1, bearing in mind the specific treatment of the affected areas as well as flood prevention. In order to do this, we have taken into account the following: a the analysis of the evolution of State regulations as regards soil occupancy in the greater Buenos Aires; b the updated registry of regulations connected with land demarcation and use of soil validated by the Executive Power (Regulation N§ and Validating Decree N§; c the specific regulation (Regulation N§ / Executive Power decree N§ by municipality / by content. The data to perform the study of regulatory soil use was obtained from the new Interactive Land Demarcation Map of the Province of Buenos Aires created by the Ministry of Government of the Province of Buenos Aires, Subsecretariat of Municipal Affairs. The analysis of current regulations in each of the 23 counties comprised in the study will allow us to define future intervention strategies, which will act as instruments in connection with land regulation for each municipality's management.

    Full Text Available The Samborombón Bay [province of Buenos Aires, Argentina] is an interfase between the river-sea area [the mouth of the Río de la Plata in the Argentine Sea] and the land. The southern coastal strip of the bay has been systematically marginalized by the valuation processes which have dominated the region of the Pampas. However, various protected areas have been set up over the last 30 years, within different public [federal, provincial, municipal] and private [NGOs] jurisdictions. This paper seeks to stress the problems which have arisen around the territory's valuation and the management of the said protected areas, within the framework of the dominant economic activities [cattle-raising, fishing and tourism

    Pressure-pulse tests have been performed in bedded evaporites of the Salado Formation at the Waste Isolation Pilot Plant (WIPP) site to evaluate the hydraulic properties controlling brine flow through the Salado. Hydraulic conductivities ranging from about 10 -14 to 10 -11 m/s (permeabilities of about 10 -21 to 10 -18 m 2 ) have been interpreted from nine tests conducted on five stratigraphic intervals within eleven meters of the WIPP underground excavations. Tests of a pure halite layer showed no measurable permeability. Pore pressures in the stratigraphic intervals range from about 0.5 to 9.3 MPa. An anhydrite interbed (Marker Bed 139) appears to be one or more orders of magnitude more permeable than the surrounding halite. Hydraulic conductivities appear to increase, and pore pressures decrease, with increasing proximity to the excavations. These effects are particularly evident within two to three meters of the excavations. Two tests indicated the presence of apparent zero-flow boundaries about two to three meters from the boreholes. The other tests revealed no apparent boundaries within the radii of influence of the tests, which were calculated to range from about four to thirty-five meters from the test holes. The data are insufficient to determine if brine flow through evaporites results from Darcy-like flow driven by pressure gradients within naturally interconnected porosity or from shear deformation around excavations connecting previously isolated pores, thereby providing pathways for fluids at or near lithostatic pressure to be driven towards the low-pressure excavations. Future testing will be performed at greater distances from the excavations to evaluate hydraulic properties and processes beyond the range of excavation effects

    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.

    Full Text Available El estero El Salado es un cuerpo costero único en la región de Bahía de Banderas, México, que se encuentra sometido a la fuerte presión del crecimiento urbano de la ciudad de Puerto Vallarta, Jalisco. Su evaluación como hábitat para la avifauna acuática puede contribuir al establecimiento de las bases técnicas para la toma de decisiones acertadas en el diseño de estrategias de conservación y explotación de sus hábitats. Con este fin, de junio de 1996 a mayo de 1997, se realizó una visita mensual al estero. En cada visita se realizaron dos transectos de 250 m de largo, de la boca a la cabeza del estero, de acuerdo al método modificado del censo de transecto en banda. Se determinaron 28 especies de aves acuáticas y se contabilizaron 1,304 individuos. De acuerdo con su presencia a lo largo del año, se registraron 16 especies residentes, 11 residentes de invierno y una migratoria. Los resultados ponen de manifiesto la importancia de la zona como espacio de sustentación alimenticia, de descanso y de anidación para aves acuáticas temporales y residentes.

    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.

    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

    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)

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.

    The lower portion of the Reconquista River is highly polluted. However, little is known about the state of the high and middle basins. The aims of this work were to assess the water quality on the high and middle Reconquista River basins and to determinate if the presence of a reservoir in the river has a positive effect on the water quality. We conducted a seasonal study between August 2009 and November 2010 at the mouth of La Choza, Durazno, and La Horqueta streams at the Roggero reservoir--which receives the water from the former streams--at the origin of the Reconquista River and 17 km downstream from the reservoir. We measured 25 physical and chemical parameters, including six heavy metal concentrations, and performed a multivariate statistical analysis to summarize the information and allow the interpretation of the whole data set. We found that the Durazno and La Horqueta streams had better water quality than La Choza, and the presence of the reservoir contributed to the improvement of the water quality, allowing oxygenation of the water body and processing of organic matter and ammonia. The water quality of the Reconquista River at its origin is good and similar to the reservoir, but a few kilometers downstream, the water quality declines as a consequence of the presence of industries and human settlements. Therefore, the Roggero reservoir produces a significant improvement of water quality of the river, but the discharge of contaminants downstream quickly reverses this effect.

    Full Text Available A comienzos de 1340 se presagiaba en el Estrecho de Gibraltar una ofensiva meriní. Castilla contaba con una flota insuficiente para frenar a los musulmanes y el reino de Aragón, que también colaboraba en la vigilancia de aquellas aguas, había reducido sus efectivos al mínimo. Así las cosas, en el mes de abril la flota castellano-aragonesa sufrió una aplastante derrota en la Ensenada de Getares, a la que siguió el traslado de un importante contingente marroquí a la Península y el posterior cerco a Tarifa. Alfonso XI, con la ayuda del rey de Portugal, acudió a descercar esta plaza y acabó imponiéndose en la batalla del Salado. Las consecuencias posteriores de esta victoria resultaron fundamentales para el dominio del Estrecho.At the beginning of 1340, a Merini attack was expected in the Straits of Gibraltar. The kingdom of Castile had an inadequate navy to stop the Muslims, and the Aragón’s kingdom, which also helped in the surveillance of that sea area, had reduced his troops to the minimum. In April, the Castilian - Aragonese navy suffered a crushing defeat in the Getares inlet, followed by the pass of one important Moroccans’ contingent to the Peninsula and the later siege to Tarifa. Alfonso XI, with the help of the King of Portugal, came to free the city from the siege, and later on he won the Salado Battle. The subsequent consequences of this victory were essential for the Straits control.

The main characteristic of the very first association, the Asociación Médica Bonaerense, was its ambivalent attitude in regards to doctor's and professor's elitism. Following the decline of this association, due to the creation of the Academia de Medicina de Buenos Aires, its more pugnacious facet was retaken by the Círculo Médico Argentino, who attempted to unite both students and young teacher's interests aims.

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.

    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.

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 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.

    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.

    In March 2015 unusual ocean and atmospheric conditions produced many years' worth of rainfall in a 48 h period over northern Chile's Atacama Desert, one of Earth's driest regions, resulting in catastrophic flooding. Here we describe the hydrologic and geomorphic drivers of and responses to the 2015 Atacama floods. In the Salado River, we estimated a flood peak discharge of approximately 1000 m3/s, which caused widespread damage and high sediment loads that were primarily derived from valley-fill erosion; hillslopes remained surprisingly intact despite their lack of vegetation. In the coastal city of Chañaral, flooding of the Salado River produced maximum water depths over 4.5 m, meters thick mud deposition in buildings and along city streets, and coastal erosion. The Atacama flooding has broad implications in the context of hazard reduction, erosion of contaminated legacy mine tailings, and the Atacama's status as a terrestrial analog for Mars.

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 This article explores citizenship formation in institutional settings. Based on life stories and participant observation, it studies how street youth in Buenos Aires experience State institutions in charge of children and youth at risk. It analyzes the level of involvement, the demands, the expression of needs and negotiations that take place within various public institutions and explores how these interactions shape the process of citizenship formation. Results suggest three different institutional trajectories amongst street youth that lead to different processes of citizenship formation.

    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 Las grandes ciudades latinoamericanas se debaten actualmente entre dos procesos de transformación socio-territorial convergentes: la densificación y verticalización de las áreas centrales, y la expansión cada vez más difusa y fragmentada de los suburbios. Esta dicotomía entre ciudad compacta y ciudad dispersa parece mostrar procesos singulares en el caso de la región metropolitana de Buenos Aires. A partir de los años dos mil, se han ralentizado los nuevos lanzamientos de urbanizaciones cerradas y, paralelamente, han comenzado a manifestarse algunos casos de revitalización de antiguas subcentralidades del sur de la metrópolis, que habían entrado en una fase de estancamiento y deterioro desde mediados de los años setenta, y actualmente experimentan una aceleración de la producción de vivienda multifamiliar de calidad. Este trabajo explora y muestra algunas experiencias concretas de esta tendencia, con la hipótesis que, al menos en Buenos Aires, los procesos de transformación y reestructuración metrolitana muestran complejidades y diversidades según los contextos temporales y territoriales que se analicen. The large Latin American cities are currently experiencing two convergent socio-territoria transformation processes: the densification and verticalization of central areas, and the increasingly diffuse and fragmented suburban expansion. This dichotomy between the compact city and the dispersed city seems to show unique features in the case of the metropolitan region of Buenos Aires. After the 2000s, the expansion of gated communities has slowed down and at the same time some old subcentralities in the South of the metropolis have begun to revitalize. Since the mid-1970s, they had entered a phase of stagnation and deterioration, and at present the production of quality multifamily housing is rapidly growing. This paper reflects on this trend and show some concrete experiences. Our hypothesis is that in Buenos Aires the process

    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.

    Full Text Available BACKGROUND: The estimated prevalence of HCV infection in Argentina is around 2%. However, higher rates of infection have been described in population studies of small urban and rural communities. The aim of this work was to compare the origin and diversification of HCV-1b in samples from two different epidemiological scenarios: Buenos Aires, a large cosmopolitan city, and O'Brien, a small rural town with a high prevalence of HCV infection. PATIENTS AND METHODS: The E1/E2 and NS5B regions of the viral genome from 83 patients infected with HCV-1b were sequenced. Phylogenetic analysis and Bayesian Coalescent methods were used to study the origin and diversification of HCV-1b in both patient populations. RESULTS: Samples from Buenos Aires showed a polyphyletic behavior with a tMRCA around 1887-1900 and a time of spread of infection approximately 60 years ago. In contrast, samples from ÓBrien showed a monophyletic behavior with a tMRCA around 1950-1960 and a time of spread of infection more recent than in Buenos Aires, around 20-30 years ago. CONCLUSION: Phylogenetic and coalescence analysis revealed a different behavior in the epidemiological histories of Buenos Aires and ÓBrien. HCV infection in Buenos Aires shows a polyphyletic behavior and an exponential growth in two phases, whereas that in O'Brien shows a monophyletic cluster and an exponential growth in one single step with a more recent tMRCA. The polyphyletic origin and the probability of encountering susceptible individuals in a large cosmopolitan city like Buenos Aires are in agreement with a longer period of expansion. In contrast, in less populated areas such as O'Brien, the chances of HCV transmission are strongly restricted. Furthermore, the monophyletic character and the most recent time of emergence suggest that different HCV-1b ancestors (variants that were in expansion in Buenos Aires had the opportunity to colonize and expand in O'Brien.

Predictores fueron seleccionados basándose en la significancia estadística, la independencia y la explicación física de su relación y utilizados como variables de entrada para generar una regresión lineal múltiple con el método "forward stepwise". Ellos son la altura geopotencial de 1000 hPa sobre la costa del océano Atlántico alrededor de 25ºS y el viento zonal en el centro de América del Sur. La lluvia estival depende principalmente del debilitamiento del anticiclón del Atlántico y de la advección de aire húmedo desde el norte del país. La verificación se realizó para los datos del período 1984-2007 obteniendo una correlación entre la serie observada y estimada de 0.61. La estabilidad del modelo se probó con la metodología de la crossvalidación.

    Full Text Available Abstract The aim of this work was to describe the phenotypic and genotypic variability related to iris color for the population of Buenos Aires province (Argentina, and to assess the usefulness of current methods of analysis for this country. We studied five Single Nucleotide Polymorphisms (SNPs included in the IrisPlex kit, in 118 individuals, and we quantified eye color with Digital Iris Analysis Tool. The markers fit Hardy-Weinberg equilibrium for the whole sample, but not for rs12913832 within the group of brown eyes (LR=8.429; p=0.004. We found a remarkable association of HERC2 rs12913832 GG with blue color (p < 0.01 but the other markers did not show any association with iris color. The results for the Buenos Aires population differ from those of other populations of the world for these polymorphisms (p < 0,01. The differences we found might respond to the admixed ethnic composition of Argentina; therefore, methods of analysis used in European populations should be carefully applied when studying the population of Argentina. These findings reaffirm the importance of this investigation in the Argentinian population for people identification based on iris color.

    The growth and changes--by age, sex, and place of birth--in the structure of the total population of the Buenos Aires metropolitan area and of the subpopulation over 15 years of age and economically active are analyzed for the decade of the 1980s. Study of the economic participation of migrants and its possible influence on levels of employment or unemployment should be carried out within the framework of changes in the population's structure and economic participation. The 1981 and 1991 censuses and the Permanent Survey of Households were the sources of data. Immigration to Argentina has declined considerably in recent years, but it is still a factor in the population growth of metropolitan Buenos Aires. Between the 1981 and 1991 censuses, the population aged 15 and over grew by 10.9/1000, or a total of 827,806 people. Migrants from bordering countries increased in number (by 85,109, or 10.3%) and in proportion to the total population (from 3.9% to 4.6%). Migrant women increased at the highest rate (30.1/1000). The greatest growth occurred among men aged 40 and over and among women aged 35 and over. The growth of the economically active population over age 15 for different groups of national origin, sex, and age showed much greater heterogeneity. In 1991, women from bordering countries represented 3.8% of all women in metropolitan Buenos Aires but 5.7% of the total economically active female population and nearly 7% of the economically active female population aged 35 and over. Women from neighboring countries were responsible for 10.3% of the growth in the economically active female population aged 30-34 and 40-44 between 1981 and 1991. The absolute and relative increases in migrants from neighboring countries and their greater economic participation tend to increase the general level of economic activity.

    Full Text Available The increasing migration of Peruvian citizens to Buenos Aires is a recent phenomenon, and the intensification of the development of organizations and their public presence are correlated with the participation in festivities, civic organizations and the like. This article is a preliminary report on research that focuses on Peruvian dance groups in Buenos Aires and that proposes to describe some of the ways that Peruvian folkdances are transmitted. I show how a process of non formal education is shaped by the interactions among dance groups and between them and representatives of the Peruvian Government in Buenos Aires; and how it is influenced by the need to «demonstrate through performance,» by ways of participating in the groups and by the previous knowledge of the dances that the performers bring with them. The analysis focuses on the microanalytic dimension of representations and practices of the dancers and directors of the dance groups. The fieldwork was carried out in the period 2005-2008 and focused on four groups of Peruvian folk dancers. The phenomena studied are shown to have great potential as intercultural mediators that transcend cultural manifestations to become mechanisms of consciousness raising that reach out to publics beyond the Peruvians themselves.

    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.

    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{sub x}) caused by the combined operation of the thermal power plants. Although the prototype deals exclusively with NO{sub 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.

    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.

To that end, this article focuses on the cases of three Afro-Descendant porteña women who, by local standards, are fully white.  Their stories allow us to explore, in the first place, how categories like “black,” “white,” and others are used and understood in contemporary Buenos Aires and how this use configures two types of blackness (racial blackness and popular blackness and makes it impossible for mestizaje categories to emerge. In the second place, through these cases this article explores how people’s very “ways of being” are at play, creating a discriminatory and oppressive environment for people at risk of not matching the ideal of the nation.

    Vehicular traffic is the main source of platinum group elements (PGEs) in highly populated urban areas like Buenos Aires where a traffic density of 1,500,000 vehicles day{sup -1} (corresponding to 7500 vehicles km{sup -2}) is estimated. Since there is no information on the levels of PGEs in Buenos Aires, a pilot study was undertaken to ascertain the amount of two major PGEs, namely Pt and Rh, in the atmosphere of this city. To this end, 49 samples of PM-10 particulate matter were collected during 7 days in seven representative sampling sites located downtown Buenos Aires and spread over an area of about 30 km{sup 2}. The collection of particulate matter was performed on ash-free glass-fiber filters using high volume samplers with PM-10 sampling heads. Filters loaded with the particulate matter were subjected to microwave (MW)-assisted acid digestion using a combination of HNO{sub 3}, HF and HClO{sub 4}. The resulting solutions were evaporated and then diluted with 0.1 mol l{sup -1} HCl. Analyses were performed by sector field inductively coupled plasma-mass spectrometry (SF-ICP-MS) and special attention was paid to the control of mass interferences. Statistical analysis was performed on the experimental data obtained for the element concentrations taking also into account local meteorological data for the monitored period. The highest concentrations of Pt and Rh were detected at two sites (Hospital Aleman and Casa Rapallini) located in streets with traffic consisting mostly of passenger cars. The Pt content (in pg m{sup -3}) in airborne particulate matter was found to vary from 2.3 to 47.7, with a mean value of 12.9+/-7, and that of Rh from 0.3 to 16.8, with a mean value of 3.9+/-2.8. These concentrations are by far below the levels for which adverse health effects might be expected to occur, i.e., around 100 ng m{sup -3}. On the other hand, monitoring of PGEs should be carried out in a systematic fashion to detect possible dramatic increases from today

    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.

In this work we present satellite as well as ground Aerosol Optical Depth (AOD) at 550 nm data obtained during the propagation of pollution clouds to the central zone of Argentina. The highest value (1.18) was registered at Buenos Aires by atmospheric remote sensing, using the satellite instrument MODIS/Terra on April 18th 2008 at 10:35 local time (= UT - 3 h). On the same day, ground air quality detectors also measured in this city the highest Total Suspended Particle (TSP) value of the month, 2.02 mg/m3. The AOD(550) daily variation at Rosario Astronomical Observatory, which is located near the Paraná riverside, was derived by combining solar ultraviolet erythemal irradiance data (measured with a YES biometre) with model calculations. On April 25th 2008, from 12:00 to 15:30 local time, a rather high and constant AOD(550) value was registered, with a mean value of (0.90 ± 0.21). Cities located on the side of the Rosario-Buenos Aires highway (San Nicolás, Baradero and San Pedro) were also affected, showing a mean AOD(550) between the Rosario and Buenos Aires values. The particulate matter was collected with gridded samplers placed on the Paraná river islands as well as at the Rosario Observatory. They were analysed with a Scanning Electron Microscope (SEM) and mainly showed a biological origin. Even if normally large particles travel small distances from the source, organic aerosol in the range of 40-100 μm and complex asymmetric structures were registered several kilometres away from the aerosol sources on the islands. Another event of intense UV index attenuation (98.6%) occurred on September 18th 2008, due to very dense

    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.

    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.

    The case of Buenos Aires (13 million inhabitants) exemplifies the evolution of energy supply and distribution in a developing metropolis characterized by the growth of consumption, spatial extension and social contrasts. After the 2001 economic and political crisis, the energy sectors underwent a major reorganization. For the city this meant growing state intervention in energy supply, private firms and the fixing of energy prices. The resulting evolution does not meet the criteria of energy transition as conceived in Europe, but it highlights the weight of the federal government upon a fragmented metropolis where local actors struggle to find their own spaces of action

    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

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.

We asked residents their opinion about CPTGs and, also, if they followed their recommendations in clinical practice. We asked 59 mental health residents (28 physicians and 29 psychologists with different years of clinical training to fill a questionnaire to know their opinion about CPTGs and also if they follow the CPTG recommendations in their clinical practice. We found that 79.31% of residents did not know any CPTG. Eighty percent of the residents who did know any CPTG have a positive opinion about CPTGs. Finally, the American Psychiatric Association Guidelines were the most known CPTGs. The authors emphasize the need for a clinical guidelines diffusion policy in Buenos Aires city and particularly as a clinical and training resource for mental health residents.

    Full Text Available Argentina declaró el uso racional y la eficacia energética una prioridad nacional, en consonancia con las recomendaciones de la Agencia Internacional de la Energía. Buenos Aires se ha comprometido con varios programas internacionales de preparación al cambio climático. Así a distintas escalas surgen iniciativas para modificar las condiciones y modalidades de aprovisionamiento y consumo energéticos, que revelan la precariedad y vulnerabilidad del sistema y los servicios. Este trabajo presenta una reflexión sobre los cambios que se dan en ese sentido, mostrando los inconvenientes del modelo energético argentino en Buenos Aires y las estrategias o medidas que tienden a revertirlos y a preparar la ciudad para situaciones críticas. En general, se trata de iniciativas que se implementan individual o parcialmente, sin que haya un plan integral promovido a escala colectiva. Las correcciones resultan marginales en el conjunto sin aliviar los problemas que se agravan por el crecimiento vertiginoso de las demandas. Entonces la continuidad del modelo energético argentino basado en hidrocarburos, para abastecer infraestructura que trabaja al límite de su capacidad y servir territorios que no se han preparado para las posibles crisis, explicaría la vulnerabilidad del sistema de abastecimiento metropolitano.

We surveyed 35 transects located along secondary roads. Bird pest abundance was significantly higher at those sites with presence of woodlots (p<0.0001. Species-specific analyses revealed that abundance of both monk parakeet and picazuro pigeon was sensitive to the frequency of woodlots of tall and perennial tree species (Eucalyptus spp.; p<0.001, whereas eared dove abundance increased significantly with the frequency of woodlots composed by short and perennial tree species (Pinus spp., Casuarina spp.; p=0.002. Most bird pest species in the study area are more sensitive to the presence of woodlots rather than to the presence of croplands in the rural landscape. These results have practical implications, suggesting that an effective control of bird pest species in Buenos Aires province could be attained by managing exotic perennial tree species woodlots.

    2011-06-01

    In no other epoch of Western history like in the Middle Ages, cosmology was so key an element of culture and, one way or another, the motion of the heavens ended up impregnating the literature of that time. Among the most noteworthy poets we find Dante Alighieri, who became famous for his Commedia, a monumental poem written roughly between 1307 and his death in 1321, and which the critics from 16th century onwards dubbed Divina. In this and other works, Dante pictures the cosmic image for the world, summing up the current trends of Neoplatonic and Islamic traditions. The Barolo Palace in the city of Buenos Aires is a singular combination of both astronomy and the worldview displayed in Dante's poetic masterpiece. Some links of the Palace's main architectural structure with the three realms of the Comedy have been studied in the past. In this note we consider its unique astronomical flavor, an issue which has not been sufficiently emphasized yet.

The collections under study came from private hands, having been gathered by collectors who relinquished them so these museums could be formed. At the same time that these collections became public, the collectors themselves became responsible for them in the role of directors of the new institutes. Within this context, the collectors established institutional relations that allowed them to devise common strategies concerning the receipt, selection, and exhibition of archeological collections. The result was the shaping of a network of solidarity in the southern part of Buenos Aires province.

    Buenos Aires׳ informal recyclers (cartoneros) confront multiple health hazards in their work. Based in a survey with (n=397) informal recyclers, this study establishes that these workers experience uneven health landscapes as evidenced through their health outcomes, the social determinants of their health, and their living and working environments. I argue that the analytical framework of urban political ecology can provide insights to the ways that the urban environments where cartoneros live and work are socially-constructed phenomena, drawing on concepts of crisis, metabolism, and multi-scalar analyses.

    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 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.

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 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.

    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.

    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)

    The coast of the Province of Buenos Aires, Argentina, has been studied to determine the wave-power potential. Using wave data (4 yr) from accelerometers, pressure sensors (1 yr) and a visual observation program (10 yr), the wave-power density was calculated at five locations. The annual average increases southwards, ranging between 2.3 kW/m at Mar de Ajo and 7.5 kW/m at Puerto Quequen. Annual averages of maximum wave power give 69 and 61.3 kW/m for Punta Medanos and Puerto Quequen, respectively. (Author).

    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.

    Participatory Democracy in Buenos Aires? An analysis of the citizen participation mechanisms performance Abstract: The paper presents the results of the incorporation and functioning of participation mechanisms in Buenos Aires city since 1996 as a response of governments to the crisis of political representation. It seeks to understand the influence of these mechanisms on the local “impure” democracy as alternative and/or complementary channels to the traditional representative way for filing civil claims in instances of political decision making. The methodology combines a literature review, an analysis of documents and the study of the constitutional creation and legislative regulation of these mechanisms, with the count of instances of application and the selection of the most relevant cases. Finally, it performed a comparative study of those cases. In principle the findings highlight the number, variety and high regulation of these mechanisms in Buenos Aires, but then they show the poor empirical results obtained in terms of their contribution to the civic participation and to strengthening democratic. Key words: Crisis of Representation – Citizen participation - Semidirect mechanisms – Political will

    Full Text Available In recent decades, rural areas near Bahía Blanca (Buenos Aires, Argentina struggle with many changes as a result of economic and technological transformations. Tese changes have limited rural communities' economic development options, making older development strategies less viable and forcing many to look for nontraditional ways to sustain themselves. One of the most popular strategies has been tourism and recreational activities. The purpose of this article is to establish how public and private initiatives are linked to the local development process. The interviews carried out made it possible to observe a process of transformation in the territory, which involves institutions, organization of actors, and strategies for addressing challenges and opportunities.

    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.

    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.

    Full Text Available 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 ABSTRACT The mainland population of the ruddy-headed goose (Chloephaga rubidiceps breeds in southern Patagonia and winters in the south of Buenos Aires province (Argentina, with a recent estimated size at around 900 individuals. 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.

    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.

    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.

    Full Text Available Se estudio la correlación entre dieta y morfología de 19 especies de peces del arroyo Manantiales, cabecera del río samborombón, provincia de Buenos Aires, Argentina. Las especies fueron clasificadas en cuatro grupos tróficos: carnívoros, omnívoros, insectívoros y detritívoros- alguívoros. Se analizaron 12 atributos ecomor-fológicos relacionados con el uso del hábitat y la alimentación con el fin de distinguir patrones ecomorfológicos de las especies y de las especies con el alimento consumido. Se utilizaron técnicas de análisis univariado y multivariado para determinar agrupamientos de especies utilizando los atributos ecomorfológicos y la dieta como descriptores. Los carnívoros se relacionaron con un buen desarrollo de cabeza, boca, aletas caudal y pectoral; y en general con cuerpos comprimidos. Los omnívoros constituyeron un grupo más heterogéneo. Las formas nectónicas de este grupo se relacionaron con un cuerpo comprimido, ojos laterales y tamaño relativamente pequeño de las aletas pectorales y aleta caudal; las formas nectobentónicas se relacionaron con boca pequeña, cuerpo fusiforme y pedúnculo caudal largo; y las formas bentónicas, con cuerpo deprimido, ojos de posición dorsal, boca ínfera y tubo digestivo largo. La única especie nectónica consumidora de insectos sobre la superficie se caracterizó por un cuerpo fuertemente comprimido, ojos laterales, aleta caudal grande y boca grande orientada hacia arriba. Los detritívoros-alguívoros presentaron un tubo digestivo largo, boca ínfera o terminal y aletas caudales largas. La relación significativa dieta-ecomorfología permite sostener que peces de dieta similar convergen hacia atributos ecomorfológicos comunes.The present study addresses the correlation between diet and morphology of 19 fish species that inhabit the Manantiales stream at the headwaters of the samborombón river, Buenos Aires province, Argentina.

    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.

    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.

    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.

    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 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.

    Full Text Available The city of Buenos Aires was founded, for the second time 1580 essentially as an outpost of the Spanish Empire to be protected from Indian attacks and possible foreign incursion, basically Portuguese in origin. Thus, from the beginnings of the city's founding, African slaves were used for the defense of the city. They acted in the urban militias, and were outstanding in the defense and re-conquest of the city when the English attacked in 1806- 1807. Innumerable prizes and eulogies were followed by integration of segregated divisions with a white officer corps.After 1813, a series of decrees ordered owners to exchange slaves for use in the Wars of Independence. Thus, property owners were obliged to sell to the State a number of their slaves according to the work performed by the slaves. The slaves would enter the armies as free persons and would serve five years as 'front line" soldiers in order to obtain their freedom. This article studies the participation of the Afro-Argentines in the distinct 'fronts" of the armies of liberation. The paper also reflects on the opinions of the generals who commanded Afro-Argentine troops.//La ciudad de Buenos Aires fue fundada, por segunda vez, en 1580 esencialmente como un puesto de avanzada para que los españoles se protegieran de los indígenas y de una posible incursión extranjera de origen portugués. Por lo tanto desde la fundación de la ciudad los esclavos africanos fueron empleados para su defensa. Los esclavos actuaban en milicias urbanas y sus acciones fueron decisivas para la defensa y reconquista de Buenos Aires cuando los ingleses la atacaron en 1806-1807.

    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. Los resultados más relevantes de esta investigación serán progresivamente publicados en sucesivos números de Actualizaciones en SIDA. PMID:25264397

    The Azul River basin, with some 6200 km{sup 2}, is located in the plains of Buenos Aires Province, Argentina. The Azul River flows along 160 km from the Tandilia Range, in the SW, to the Channel 11, in the NE. Average annual precipitation is 1005 mm (1988-2000); mean reference evapotranspiration is 1090 mm. The geology consists of Miocene to recent sediments, mostly sands and silts with some clay and calcrete layers, overlying crystalline rocks and marine sediments. The water table is shallow and groundwater in the aquifer upper 30 m displays an increasing salinity from SW to NE. The previous hypothesis to explain the salinity was infiltration of evapo-concentrated surface water, as the small soil slope in the northern basin (< 0.2%) induces rainfall accumulation in lowlands, where water evaporates prior to infiltration. But recent chemical and isotopic data reveal two salinity sources: evaporation of recent recharge water, and mixing with old saline groundwater of yet unknown origin. (author)

    Room Q is a 109-m-long cylindrical excavation in the Salado Formation at the Waste Isolation Pilot Plant (WIPP) site. Fifteen boreholes were drilled and instrumented around Room Q so that tests could be conducted to determine the effects of room excavation on the hydraulic properties of the surrounding evaporate rocks. Pressure-buildup and pressure-pulse tests were conducted in all of the boreholes before Room Q was mined. The data sets from only eight of the boreholes are adequate for parameter estimation, and five of those are of poor quality. Constant-pressure flow tests and pressure-buildup tests were conducted after Room Q was mined, producing eleven interpretable data sets, including two of poor quality. Pre-mining transmissivities interpreted from the three good-quality data sets ranged from 1 x 10{sup -15} to 5 x 10{sup -14} m{sup 2}/s (permeability-thickness products of 2 x 10{sup -22} to 9 x 10{sup -21} m{sup 3}) for test intervals ranging in length from 0.85 to 1.37 m. Pre-mining average permeabilities, which can be considered representative of undisturbed, far-field conditions, were 6 x 10{sup -20} and 8 x 10{sup -20} m{sup 2} for anhydrite, and 3 x 10{sup -22} m{sup 2} for halite. Post-mining transmissivities interpreted from the good-quality data sets ranged from 1 x 10{sup -16} to 3 x 10{sup -13} m{sup 2}/s (permeability-thickness products of 2 x 10{sup -23} to 5 x 10{sup -20} m{sup 3}). Post-mining average permeabilities for anhydrite ranged from 8 x 10{sup -20} to 1 x 10{sup -19} m{sup 2}. The changes in hydraulic properties and pore pressures that were observed can be attributed to one or a combination of three processes: stress reduction, changes in pore connectivity, and flow towards Room Q. The effects of the three processes cannot be individually quantified with the available data.

    Full Text Available A Colônia do Sacramento, no atual Uruguai, na primeira metade do século XVIII, constituiu uma cidade de pródigo comércio na região platina. Inseridos tanto nas rotas comerciais e sociais portuguesas quanto nas castelhanas, os habitantes de Sacramento materializavam uma fronteira múltipla, onde coexistiam espanhóis, portugueses e diferentes grupos indígenas. O presente estudo analisa os vínculos sociais e comerciais existentes entre os habitantes de Sacramento e os de Buenos Aires. No interior do espaço platino as redes sociais estabelecidas através do rio da Prata, ligando Sacramento e Buenos Aires, eram vias de acúmulo de prestígio, poder e riqueza em uma sociedade de antigo regime.The Sacramento Colony, currently Uruguayan territory, in the first half of the XVIII century, was a city with great commerce on the River Plate Region. Placed in both Portuguese and Spanish social and commercial routes, the Sacramento habitants formed a multiple frontier where Spanish, Portuguese and different indigenous groups coexisted. The present study analyses the social and commercial links that existed between the Sacramento and Buenos Aires inhabitants. In the River Plate region, the social networks developed connecting Sacramento and Buenos Ayers were gateways to social status, power and wealth in an old regime society.

    Full Text Available This paper seeks to examine the global organization of two Spanish American colonial spaces during the era of free trade: the Hispanic North and Rio de la Plata. By studying the consular records on foreign trade, included in the derecho de avería records, I analyse how their economies were integrated into the circulation of silver, slaves, and imports. Moreover, I explain the institutional development of their trade communities, favored by the body of consulates in the cities of Guadalajara and Buenos Aires, viewed as institutional instruments of corporate negotiation, market administration, and interest organization against a backdrop of trade globalization.

    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

    Full Text Available O uso de imagens SAR para estimar e monitorar a umidade superficial do solo requer que se considere outros fatores que influenciam na retrodifusão do sinal-radar, entre os quais a rugosidade da cobertura da superfície à escala de centímetro é muito importante. 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.

Par ses caractéristiques la figure mythique du preneur de graisse andin ne peut correspondre à une divinité. La fonction symbolique de la graisse dans les cultures andines préhispanique et actuelle lui donne un premier sens indigène. Les vertus pratiques de la graisse humaine dans la médecine européenne du XVIIè siècle, ainsi que les données d’ethnographie espagnole, lui donnent sa signification dans l’histoire coloniale.

En la provincia de Buenos Aires el sistema ha sido profundamente modificado en los últimos 15 años siguiendo las premisas de la Convención Internacional sobre los Derechos del Niño y dejando relegado el modelo del Patronato, que había regido previamente. Las instituciones encargadas de la ejecución de la intervención dispuesta por el Poder Judicial dependen actualmente de la Subsecretaria de Niñez y Adolescencia del Ministerio de Desarrollo Social y constan de centros cerrados, centros con régimen de semilibertad y centros de intervención ambulatoria (medidas alternativas a la prisión, tales como suspensión de juicio a prueba o tareas comunitarias. Las ciencias relacionadas con la salud mental y con el comportamiento vienen contribuyendo a la identificación de diversos factores influyentes en la conducta disocial y con el diseño de tipos de intervención para cada nivel de prevención. Sin embargo, hay una distancia importante entre las potencialidades del estado actual delconocimiento y la implementación. En las condiciones expuestas, queda configurado un período de transición que aún requiere optimización de la política de infancia con ajustes legislativos, judiciales y administrativos y con la capitalización de los aportes científicos.

    Geohydrologic data have been collected in the Los Medanos area at the US Department of Energy's proposed Waste Isolation Pilot Plant (WIPP) site in southeastern New Mexico since 1975 as part of a study evaluating the feasibility of storing defense-associated nuclear wastes within the bedded salt of the Salado Formation of Permian age. Drilling and hydrologic testing have identified three principal water-bearing zones above the Salado Formation and one below that could potentially transport wastes to the biosphere if the proposed facility were breached. The zones above the Salado are the contact between the Rustler and Salado Formations and the Culebra and Magenta Dolomite Members of the Rustler Formation of Permian age. The zone below the Salado Formation consists of channel sandstones in the Bell Canyon Formation of the Permian Delaware Mountain Group. Determinations of hydraulic gradients, directions of flow, and hydraulic properties were hindered because of the negligible permeability of the water-bearing zones. Special techniques in drilling, well completion, and hydraulic testing have been developed to determine the hydrologic characteristics of these water-producing zones

  9. Sidestream Elevated Pool Aeration, a Technology for Improving Water Quality in Urban Rivers

    Dissolved Oxygen (DO) levels are frequently depleted in rivers located in urban areas, as in the case of the Matanza-Riachuelo River in Buenos Aires, Argentina. This stream receives both domestic and industrial loads which have received minor or no treatment before being discharged into the water body. Major sources of pollution include, but are not limited, to leather and meat packing industries. Additionally, deep slow moving water in the river is associated with limited reaeration and facilitates deposition of organic-rich sediment, therefore exacerbating the DO consumption through sediment oxygen demand. In this study we assessed the efficiency of Sidestream Elevated Pool Aeration (SEPA) stations as a technology for alleviating conditions characterized by severely low DO levels. A SEPA station takes water from the stream at low DO concentrations, through a screw pump; then, water is transported to an elevated pool from where it flows over a series of weirs for water reaeration; finally, the aerated water is discharged back into the river sufficiently downstream from the intake point. This system mimics a phenomenon that occurs in mountain streams, where water is purified by bubbling over rocks. The impact of the use of SEPA stations on the DO concentrations in the Matanza-Riachuelo River was evaluated at both local and reach scales: this was done by deploying and monitoring an in situ pilot SEPA station, and by performing numerical modeling for the evaluation of the hydrodynamics in the SEPA station and the water quality in the reach where SEPA stations are planned to be implemented. An efficiency of aeration of 99% was estimated from DO measurements in the pilot SEPA, showing the potential of this technology for DO recovery in urban streams. Three-dimensional hydrodynamic modeling, besides assisting in the design of the pilot SEPA, has allowed for designing a prototype SEPA to be built soon. Finally, one-dimensional water quality modeling has provided the

    The activity concentrations of both natural (238U and 232Th chains and 40K) and anthropogenic (137Cs) 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 57Fe Mössbauer spectroscopy characterization, pH, texture and organic carbon content measurements. From Mössbauer results, the sample compositions differ from one area to the other. Spectra from both soil samples are dominated by the Fe3+ paramagnetic signal. For soil samples from the coastal area, the α-Fe2O3 contribution is lower, Fe3O4 was not detected, and the relative areas of each spectral contribution are nearly constant with depth. For samples from the inland area, the Fe3+ paramagnetic fraction increases up to 82%, mainly at the expense of the magnetically ordered phase. The main observed activity originates from the decay of 40K (540-750 Bq/kg), followed by 238U (60-92 Bq/kg) and 232Th (37-46 Bq/kg) chains. The activity of 235U was in all the cases lower than the detection limit (LD = 0.02 Bq/kg). The only determined anthropogenic nuclide was 137Cs, 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 Mössbauer relative fractions was found, whereas no correlation was found between the 137Cs profile and the relative fraction of Fe3O4 or with other iron species.

    This paper describes the environmental characteristics and situation of aquatic habitats and communities in southern continental and maritime areas of southeastern South America (Patagonian Shelf GIWA Subregion), resulting from an overall assessment carried out within the framework of a GIWA project, mostly on the basis of publicly available data. The main focus of the analysis was on the current situation of transboundary water resources and anthropogenic impacts. In the inland waters, habitat and community modifications result, principally, from dams and reservoirs built in the main watercourses for hydroelectric power generation and other uses. The transformation of lotic environments into lentic ones have affected habitats and altered biotic communities. In the La Plata River basin, invasive exotic species have displaced native ones. Habitats in the ocean have been degraded, as their biodiversity becomes affected by overfishing and pollution. This article includes a discussion on the causal chain and the policy options elaborated for the Coastal Ecosystem of Buenos Aires province and the Argentinean-Uruguayan Common Fishing Zone, where fishing resources are shared by both countries.

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.

Las muestras fueron obtenidas entre 1991 y 1997 (23 en primavera, 16 en verano, 10 en otoño y 13 en invierno, en las localidades de La Balandra y Punta Blanca, partido de Magdalena, provincia de Buenos Aires. Ambos sexos fueron analizados en conjunto debido a que no se encontraron diferencias significativas en el número y en el peso de las presas consumidas por machos y hembras (U de Mann-Whitney. La dieta estuvo compuesta en un 100 % por ítemes de origen animal, representada por 92 entidades taxonómicas. Los invertebrados constituyeron más del 96% de la muestra por número, y los vertebrados un 31% del peso total. Los insectos fueron hallados en el 98% de las muestras, representando el 85% y 59% en número y peso del total consumido, respectivamente. En los contenidos estomacales se hallaron además anélidos, moluscos, crustáceos, arácnidos, anfibios, reptiles y aves. Estacionalmente no se encontraron diferencias significativas en el número de las presas capturadas. En lo referente al peso, las muestras de invierno resultaron más pesadas que las de primavera y verano (Kruskal-Wallis.

    Full Text Available The present work was developed in the West of Buenos Aires Province (Argentina with the objective of adjusting functions of biomass of individual trees, in their different compartments and in the understorey. 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.

  1. 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.

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.

    Full Text Available The last Argentine military dictatorship (1976-1983 has left deep marks in different spheres of the social, and education has not been the exception. A group of educational policies were carried out in the province of Buenos Aires that strongly transformed the senses of teaching. One of those policies has been the teacher education reform and the new course of studies for the Higher Teaching in 1977. From the advances of an ongoing research and the work on historical sources –programs, plans, regulations, government decrees, acts- we will analyse this teacher education policy as part of the teachers' work regulation and as a process of practice production.

    Full Text Available An approach is proposed on the study of financial consumption in the low-income sectors of Argentina. As mentioned in multiple research studies conducted in different Latin American countries, the study of this recent and widespread phenomenon demands to highlight some of the common places that have caused the characterization of the economic life of the popular sectors. We propose some theoretical guidelines to reconsider such consumption and analyze the results of our still ongoing investigation regarding consumption and indebtedness in the lower sectors of the metropolitan area of Buenos Aires.

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.

Sedetectaron anticuerpos anti-B. canis en 16 perros (7.3%, 9 hembras y 7 machos, este último dato es relevante ya que la orina de los machos es considerada uno de los medios de diseminación de la infección. Aunque sólo se pudieron tomar hemocultivos a 175 animales, en 3 (2 hembras y un macho se aislaron B. canis.

    Full Text Available The aim of this paper is to analyze the conceptions of poverty that circulated among the elites of Buenos Aires through the eighteenth and early nineteenth centuries. 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.

    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. The participation in the aerosol analysis for the Ushuaia Global Atmospheric Watch Station is also commented. (author)

    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.

    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.

Los objetivos de este estudio fueron determinar los niveles circulantes de 25-hidroxi-vitamina D, 25(OHD, en pacientes ambulatorios ancianos y jóvenes de la ciudad de Buenos Aires y establecer el impacto de valores descendidos de Vitamina D en la remodelación ósea. 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. Se deberán evaluar las políticas sanitarias apropiadas destinadas a corregir esta deficien-cia, la cual predispone a la osteoporosis.The purpose of this study was to evaluate the level of hypovitaminosis D in elderly and young outpatients populations of the City of Buenos Aires, and to establish its impact on bone remodeling.

    Full Text Available The principal aim of this study was to provide a current description of the child and teenager maltreatment phenomenon in the Buenos Aires Province. 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.

    Full Text Available El abastecimiento de sal en cantidades sufi cientes fue una de las principales preocupaciones del Cabildo de Buenos Aires. 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

  11. Fumigating the Hygienic Model City: Bubonic Plague and the Sulfurozador in Early-Twentieth-Century Buenos Aires.

    Engelmann, Lukas

    2018-07-01

    The 1899/1900 arrival of bubonic plague in Argentina had thrown the model status of Buenos Aires as a hygienic city into crisis. Where the idea of foreign threats and imported epidemics had dominated the thinking of Argentina's sanitarians at that time, plague renewed concerns about hidden threats within the fabric of the capital's dense environment; concerns that led to new sanitary measures and unprecedented rat-campaigns supported by the large-scale application of sulphur dioxide. The article tells the story of early twentieth-century urban sanitation in Buenos Aires through the lens of a new industrial disinfection apparatus. The Aparato Marot, also known as Sulfurozador was acquired and integrated in the capital's sanitary administration by the epidemiologist José Penna in 1906 to materialise two key lessons learned from plague. First, the machine was supposed to translate the successful disinfection practices of global maritime sanitation into urban epidemic control in Argentina. Second, the machine's design enabled public health authorities to reinvigorate a traditional hygienic concern for the entirety of the city's terrain. While the Sulfurozador offered effective destruction of rats, it promised also a comprehensive - and utopian - disinfection of the whole city, freeing it from all imaginable pathogens, insects as well as rodents. In 1910, the successful introduction of the Sulfurozador encouraged Argentina's medico-political elite to introduce a new principle of 'general prophylaxis'. This article places the apparatus as a technological modernisation of traditional sanitary practices in the bacteriological age, which preserved the urban environment - 'el terreno' - as a principal site of intervention. Thus, the Sulfurozador allowed the 'higienistas' to sustain a long-standing utopian vision of all-encompassing social, bodily and political hygiene into the twentieth century.

    Full Text Available This article deals with the State regulation of drinking water and sanitation services in the Metropolitan Area of Buenos Aires. Its main objective is to identify the continuities and ruptures in State regulation during the transition from private management (1993-2006 to renationalisation and State management (2006 onwards. The concept of “State capacities” (both administrative and relational is used to assess regulatory performance. For the administrative capacities, the correspondence between the design and resources of the agencies, as well as the differences between their formal functions and actual practices, is examined. For the relational capacities, the policies of the National Government and its interaction with both the water and sanitation companies and the regulatory and control agencies are considered. The analysis is based on official documents, legislation and statistics, company balance sheets and reports, newspaper articles and semi-structured interviews.

    As part of a project which aims metal concentration assessment in urban park soils of Sao Paulo, in the present paper the concentration of the elements As, Ba, Cr, Co, Cu, Pb, Sb and Zn were determined in surface soil samples (0-5 cm and 0-20 cm) from Buenos Aires park of Sao Paulo. This park is located in central region of the city, and is surrounded by avenues and streets, with different traffic volumes. Instrumental Neutron Activation Analysis (INAA) and X-ray Fluorescence (FRX) were used for metal analysis. Preliminary results showed concentration levels of the analyzed elements higher than the values considered as reference values for soils in Sao Paulo, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB). These results suggest that these elements have anthropogenic origin and indicate a potential risk for soil quality. (author)

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

    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

    Studies using traditional screening instruments tend to report a lower prevalence of eating disorders (EDs) in men than is observed in women. It is therefore unclear whether such instruments are valid for the assessment of ED in males. Lack of a formal diagnostic definition of muscle dysmorphia syndrome (MD) makes it difficult to identify men at risk. The study aimed to assess the prevalence of ED and MD in male university students of Buenos Aires. A cross-sectional, two-stage, representative survey was of 472 male students from six different schools in Buenos Aires, mostly aged between 18 and 28 years. The first stage involved administration of self-report questionnaires (Eating Attitude Test-26; scores ≥15 indicate "at risk" status). In Stage 2 students at risk of developing EDs were evaluated with a clinical interview, the Eating Disorder Examination (EDE; 12th edition). Two control students were interviewed for every at risk student. The prevalence of EDs among university male students was 1.9% (n = 9). All participants with an ED presented with illness classified as eating disorder not otherwise specified (EDNOS). Using the Drive for Muscularity Scale (DMS) with a 52-point threshold we identified possible MD in 6.99% (n = 33) of the sample. The prevalence of ED detected in this study is comparable with previous findings in male populations, and below that observed in female populations. However, the prevalence of possible cases of MD resembles the total rate of EDs in women. Characteristics associated with EDs and MD in men are also discussed. © 2015 Wiley Periodicals, Inc.

    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.

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.

    Wastewater and solid waste from both domestic and industry have been known to give burden on river water quality. Most of river water quality problem in Indonesia has start in the upper part of river due to anthropogenic activities, due to inappropriate land use management including the poor wastewater infrastructure. Base on Upper Citarum River Water pollution problem, it is interesting to study the other main river in Java Island. Bengawan Solo River and Brantas River were chosen as the sample in this study. Parameters assessed in this study are as follows: TSS, TDS, pH, DO, and hexavalent chromium. The status of river water quality are assess using STORET method. Based on (five) parameters, STORET value showed that in Brantas River, Pagerluyung monitoring point had the worst quality relatively compared to other monitoring point in Brantas River with exceeding copper, lead and tin compared to the stream standard in East Java Provincial Regulation No. 2 in 2008. Brantas River was categorized as lightly polluted river based on monitoring period 2011-2015 in 5 monitoring points, namely Pendem, Sengguruh, Kademangan, Meritjan and Kertosono.

    SNL-12 (permitted by the New Mexico State Engineer as C-2954) was drilled to provide geological data and hydrological testing of the Culebra Dolomite Member of the Permian Rustler Formation near the margin of dissolution of halite in the upper part of the Salado south of the Waste Isolation Pilot Plant (WIPP). SNL-12 is located in the southeast quarter of section 20, T23S, R31E, in eastern Eddy County, New Mexico. SNL-12 was drilled to a total depth of 905 ft below the ground level. Below surface dune sand and the Berino soil, SNL-12 encountered, in order, the Mescalero caliche, Gatu?a, Dewey Lake, Rustler, and uppermost Salado Formations. Two intervals were cored: (1) from the lower Forty-niner Member through the Magenta Dolomite and into the upper Tamarisk Member; and (2) from the lower Tamarisk Member through the Culebra Dolomite and Los Meda?os Members and into the uppermost Salado Formation. Geophysical logs were acquired from the open hole to total depth, and the drillhole was successfully completed with a screened interval open across the Culebra. At SNL-12, the uppermost Salado cores display displacive halite crystals in clastic-rich units below an amalgamated sulfate at the top of the formation. There is no indication of thinning of the upper Salado due to postdepositional dissolution, and this is consistent with predrilling expectations.

    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. Após sua utilização, esses produtos podem chegar ao esgoto em quantidades residuais. A pressão seletiva exercida pelos antimicrobianos nos efluentes hospitalares propicia a disseminação de linhagens resistentes. Além dos

    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.

    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.

    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.

Los resultados obtenidos muestran perfiles de desempeño diferentes entre ambos grupos. El perfil de desempeño menos eficiente en términos de las variables estudiadas se observó en el grupo de niños proveniente de hogares pobres. Estos resultados constituyen un aporte significativo de un paradigma neurocientífico para la implementación de estrategias de intervención orientadas a estimular el funcionamiento cognitivo de tipo ejecutivo de niños de edad preescolar.

    1973-01-01

    The salt deposits of Los Medanos area, in Eddy and Lea Counties, southeastern New Mexico, are being considered for possible use as a receptacle for radioactive wastes in a pilot-plant repository. The salt deposits of the area are in three evaporite formations: the Castile, Salado, and Rustler formations, in ascending order. The three formations are dominantly anhydrite and rock salt; but some gypsum, potassium ores, carbonate rock, and fine-grained clastic rocks are present. They have combined thicknesses of slightly more than 4000 feet, of which roughly one-half belongs to the Salado. Both the Castile and the Rustler are richer in anhydrite and poorer in rock salt than the Salado, and they provide this salt-rich formation with considerable protection from any fluids which might be present in underlying or overlying rocks. The Salado Formation contains many thick seams of rock salt at moderate depths below the surface. The rock salt has a substantial cover of well-consolidated rocks, and it is very little deformed structurally. 37 refs., 48 figs., 4 tabs

    2010-01-01

    Intensive management of the Missouri River for navigation, flood control, and power generation has resulted in substantial physical changes to the river corridor. Historically, the Missouri River was characterized by a shifting, multithread channel and abundant unvegetated sandbars. The shifting channel provided a wide variety of hydraulic environments and large areas of connected and unconnected off-channel water bodies.Beginning in the early 1800s and continuing to the present, the channel of the Lower Missouri River (downstream from Sioux City, Iowa) has been trained into a fast, deep, single-thread channel to stabilize banks and maintain commercial navigation. Wing dikes now concentrate the flow, and revetments and levees keep the channel in place and disconnect it from the flood plain. In addition, reservoir regulation of the Missouri River upstream of Yankton, South Dakota, has substantially changed the annual hydrograph, sediment loads, temperature regime, and nutrient budgets.While changes to the Missouri River have resulted in broad social and economic benefits, they have also been associated with loss of river-corridor habitats and diminished populations of native fish and wildlife species. Today, Missouri River stakeholders are seeking ways to restore some natural ecosystem benefits of the Lower Missouri River without compromising traditional economic uses of the river and flood plain.

    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 Actualmente en la provincia de Buenos Aires, con una población de más de 15 millones de habitantes, los pueblos aborígenes representan el 0,36%. Desde mediados de los ‘40, tanto los aborígenes y sus descendientes, como los inmigrantes europeos y latinoamericanos instalados en el interior del país fueron migrando tanto a la ciudad de Buenos Aires como a su conurbano, fenómeno fomentado por la actividad industrial y agrícola-ganadera. Con el objeto de evaluar el aporte de los distintos grupos étnicos a la composición genética de la población actual de la provincia de Buenos Aires (centrándonos en CABA y conurbarno, llevamos a cabo el análisis de marcadores genéticos de herencia uni y biparental (ADN mitocondrial: región de control y SNPs de región codificante, Cromosoma Y: SNPs y SNPs localizados en cromosomas autosómicos. Los resultados obtenidos permiten interpretar los procesos migratorios y de  mestizaje que co-participaron en la constitución actual de la provincia, cuya población representa el 52% de la población total del país. De estos resultados surge un claro efecto de desplazamiento étnico ya que después de 20 generaciones del primer contacto no es posible detectar individuos que mantengan la estructura genética de las poblaciones originarias de América. Abstract In the province of Buenos Aires, with a population of over 15 million inhabitants, aboriginal people currently account for 0.36%. Since the mid-40s, aborigines and their descendants, as well as European and Latin American immigrants, settled in the major urban areas, such as Buenos Aires city and its suburbs, fueled by industrial, agricultural and livestock activities. In order to evaluate the contribution of the various ethnic groups to the genetic make-up of the extant population of Buenos Aires province, we analyzed uni- and biparental inheritance markers (mitochondrial DNA: control region and coding region SNPs, Y chromosome: SNPs and SNPs located

    Full Text Available Se determinó la seroprevalencia de leptospirosis en una población canina suburbana con el objeto de analizar la asociación entre distintas variables individuales y ambientales y la seropositividad a leptospirosis. 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 We determined the seroprevalence of leptospirosis in a suburban canine population for the purpose of analyzing the association between different individual and environmental variables and seropositivity for leptospirosis. The study, which was cross-sectional, was performed in July 1992 in a neighborhood of Greater Buenos Aires with approximately 9 500 inhabitants and a canine population of around 2 000 animals. We studied a random sample of 223 dogs and obtained a blood sample from each. Each animal’s epidemiologic history was obtained by interviewing the housewife. Serologic measurements were performed by the microagglutination technique with the use of 10 different serotypes of Leptospira interrogans. Of the 223 dogs that were tested, 57% showed seropositivity; 82% of the positive sera coagglutinated with two or more serotypes. The most frequently detected serotypes were canicola and pyrogenes.

    Drillhole DOE-2 was drilled to investigate a structural depression marked by the downward displacement of stratigraphic markers in the Salado Formation. Contrary to several hypotheses, halite layers were thicker in the lower part of the Salado, not thinner as a result of any removal of halite. The upper Castile anhydrite in Drillhole DOE-2 is anomalously thick and is strongly deformed relative to the anhydrite in adjacent drillholes. In contrast, the halite was <8 ft thick and significantly thinner than usually encountered. The lower Castile anhydrite appears to be normal. The depression within the correlated marker beds in the Salado Formation in Drillhole DOE-2 is interpreted as a result of gravity-driven deformation of the underlying Castile Formation. Several stratigraphic units were hydrologically tested in Drillhole DOE-2. Testing of the unsaturated lower portion of the Dewey Lake Red Beds was unsuccessful because of exceptionally small rates of fluid intake. Drill-stem tests were conducted in five intervals in the Rustler Formation, over the Marker Bed 138-139 interval in the Salado formation, and over three sandstone members of the Bell Canyon Formation. A pumping test was conducted in the Culebra Dolomite Member of the Rustler Formation. Pressure-pulse tests were conducted over the entire Salado Formation. Fluid samples were collected from the Culebra Dolomite Member and from the Hays Member of the Bell Canyon Formation. 31 refs., 31 figs., 5 tabs.

    This paper is an approach to AIDS as a topic among a drug abusers sample of the city of Buenos Aires. Research was carried out on the basis of a qualitative methodology. In an attempt at surveying opinions and attitudes of such a sample as regards AIDS (i.e. subjects' cognitive map), 21 drug abusers from three different rehabilitation programs operating in the B.A. area were interviewed. On the basis of the research performed, the authors elaborate communication strategies among drug abusers that would be helpful for authorities engaged in AIDS prevention to adopt. To boost a strategy likely to break up the AIDS-drug association existing in the mind of many an abuser would be highly advisable so that a separation be settled between both representations, thus giving drug abusers a higher motivation for self-care practice.

    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 aims of this study were to describe the clinical importance of NTM in patients from the North of Buenos Aires Province and the drug-susceptibility patterns in relation with the therapy used. A total of 23,624 clinical specimens were investigated during the period 2004-2010. Ziehl-Neelsen stain and cultures were used for diagnosis. Molecular and biochemical tests were performed to identify the mycobacteria. TB and mycobacterioses cases were 2 118 and 108 respectively. Sixteen NTM species were found: Mycobacterium avium and Mycobacterium intracellulare as the main causative agents. Infections produced by more than one species at the same time were confirmed (4 cases. Macrolides and fluoroquinolones were the most active in vitro drugs. Treatment evaluation showed that 68.0 % of the cases completed the therapy, 20 % died; and 12 % were relapses. The cases in which the treatment outcome was evaluated received an individual tailor-made therapeutic scheme including those drugs showing in vitro activity and presumed in vivo usefulness. More than a quarter of the patients had HIV co-infection and the majority of the deaths were associated with this co-infection.Enfermedad causada por micobacterias no tuberculosas: diagnóstico y evaluación del tratamiento en el norte del Gran Buenos Aires.

    Full Text Available This article focuses on land conflicts in those "pueblos de indios" which were able to preserve their lands until the late nineteenth century in the jurisdiction of Cordoba. It is based on a case study: the Indian town of La Toma -which was settled near the city of Cordoba- between 1790 and 1825. More specifically, it reconstructs the attempts of the Spanish chapter, the jesuits and some landowners to occupy some pieces of land in the town, and to legalize the occupation. It also looks at the indigenous strategies for the defense of their land rights, which were supported by the Royal Audience of Buenos Aires which allowed them to avoid the restrictions imposed by local courts.A partir del estudio del caso de La Toma entre fines del siglo XVIII y principios del siglo XIX, se abordan los conflictos por las tierras de aquella parte de la población indígena encomendada y asentada en la jurisdicción de Córdoba, que fue reducida en "pueblos de indios" en el siglo XVII y que logró preservar el control sobre sus tierras comunales durante los dos siglos siguientes. Específicamente, se reconstruyen los intentos del cabildo, la Compañía de Jesús y los vecinos españoles por ocupar de hecho las tierras de ese pueblo de indios asentado en las cercanías de la ciudad de Córdoba y por legalizar esa situación, así como las estrategias indígenas de defensa de sus derechos, que contaron con el apoyo de los funcionarios la Real Audiencia de Buenos Aires y permitieron eludir las trabas impuestas por la justicia local.

Centrado en la Región Metropolitana de Buenos Aires, este trabajo aborda la coordinación de políticas ambientales metropolitanas en un contexto federal. La primera parte describe la región metropolitana, el modo en que el federalismo argentino distribuye competencias ambientales entre niveles de gobierno, los mecanismos institucionales para la gestión metropolitana y las características y principales deficiencias de las organizaciones interjurisdiccionales que operan en la región metropolitana. La segunda parte discute los factores que explican esas deficiencias. Se argumenta que las fallas de coordinación metropolitana de políticas ambientales se explican por la interacción entre las instituciones federales y otras variables del sistema político, como la lógica de acumulación partidaria, la configuración de las agendas de gobierno, el papel de las burocracias estatales y el impacto del activismo ambiental.In any metropolitan region, the articulation between metropolitan scale of issues and the multiplicity of government jurisdictions poses a challenge for the implementation of environmental policies.

    The U.S. Atomic Energy Commission, through the Office of Test Operations, Albuquerque Operations Office, plans to detonate a nuclear device in a massive salt bed 1,200 feet beneath the land surface. The project, known as Project Gnome, is an element of the Plowshare program--a study of peacetime applications of nuclear fission. The location of the proposed underground shot is in a sparsely-populated area in southeastern Eddy County, N. Mex., east of the Pecos River and about 25 miles southeast of the city of Carlsbad. The area is arid to Semiarid and ground water is a vital factor in the economic utilization of the land, which is primarily used for stock raising. An investigation of the Project Gnome site and surrounding area for the purposes of evaluating the ground-water resources and the possible effect upon them from the detonation of the nuclear shot was desired by the Commission. This report describes work done by the U.S. Geological Survey on behalf of the Commission and presents results of the investigation of the ground-water resources and geology of the area. The most intensive investigations were made within a 15-mile radius of the site of Project Gnome and mainly on the east side of the Pecos River. The total area of study of over 1,200 square miles includes parts of Eddy and Lea Counties, N. Mex. The Project Gnome site is in the sedimentary Delaware Basin. It is underlain by about 18,000 feet of sedimentary rocks ranging in age from Ordovician to Recent. Upper Permian evaporitic rocks, which contain the principal source of potash available in the United States, are worked in nearby mines. The potash minerals are found in a massive salt bed about 1,400 feet thick in the Salado Formation of Permian age. The land surface of the area is covered mostly by a wind-blown sand and caliche; however, rocks of the Rustler Formation of Permian age and younger rocks of Permian, Triassic, Pleistocene(?) and Recent age crop out at several localities.

    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

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.

    The Luján River basin, which is located in the northwest area of the province of Buenos Aires, Argentina, receives different anthropogenic inputs before reaching the Río de la Plata estuary. The aim of this study was to assess the adverse impact of the river in the middle part of the basin. To this end, an in situ cage assay was conducted in two sites of the river (S1 and S2) near Luján city, and the responses of hepatic biomarkers of both a standardized (Cyprinus carpio) and a native (Pimelodella laticeps) species were evaluated. The biomarkers studied were the condition factor and liver somatic indices (LSI), the enzymatic activities of catalase (CAT), superoxide dismutase (SOD), and glutathione-S-transferase (GST), lipid peroxidation levels (thiobarbituric acid reactive substances, TBARS) and the induction of hepatic cytochrome P450 1A (CYP1A) and vitellogenin (Vtg) proteins. After 14 days, LSI and GST activity increased, and TBARS levels decreased in both species exposed at S1 and S2. In addition, exposure at both sites promoted an increase in SOD activity and CYP1A induction in C. carpio, while Vtg expression was observed only at S1. A shorter exposure period (7 days) caused an initial response only at S2 mediated only by CAT in P. laticeps. Finally, our results demonstrate that a 14-day period of in situ exposure in Luján River could lead to antioxidant and biotransformation processes in C. carpio and to phase II biotransformation responses in P. laticeps.

To this information is added an analysis of the ways in which these utensils were used within domestics contexts. The material culture of these commercial and domestic contexts is approached through the analysis of inventories found in the city’s probate records. As a result, the study suggests that both the different ways of organising food related activities within domestic contexts and the commercial supply of the related objects are partially a consequence of the social mobility and migrations propitiated by the creation of the ViceroyaltyEn este trabajo se discute la forma en que se estructuraba la oferta de objetos relacionados con las prácticas de alimentación en la ciudad de Buenos Aires durante el período virreinal (1776-1810.

El abordaje a la cultura material de los contextos, tanto comerciales como domésticos, se realiza a partir de los ítems listados en inventarios post mortem de habitantes de esta ciudad. Como resultado se plantea que tanto las diferentes formas de organizar la alimentación a nivel doméstico como la oferta comercial de objetos responden parcialmente a la coyuntura particular de movilidad social y migraciones, las cuales fueron propiciadas por la creación del Virreinato del Río de la Plata.

The Rapid Situation Assessment and Response methodology was used to obtain the information. Quantitative and qualitative techniques were triangulated: 140 current IDUs and 35 sex partners of injection drug users (IDUs were surveyed; 17 in-depth interviews with the surveyed IDUs and 2 focus groups were held, as well as ethnographic observations. The way in which risk and care practices among injecting drug users changed and the influence of the HIV/ AIDS epidemic on this process are described. In recent years, the frequency of injection practices and sharing of injecting equipment has decreased, while injecting drug use is a more hidden practice in a context of increasing impact of the disease in the injecting drug use social networks and changes in the price and quality of drugs. Knowledge about these changes helps build harm reduction activities oriented to IDUs in their particular social context.Este artículo refleja los cambios en el uso inyectable de drogas producidos entre 1998 y 2003 en Buenos Aires, Argentina.

El ensayo de detección fenotípica de MBL de sinergia con doble disco resultó útil en este estudio. Sólo aquellos aislamientos productores de IMP-13 que a su vez presentaron alteraciones en las proteínas de membrana externa resultaron completamente resistentes a imipenem. Los aislamientos productores de MBL correspondieron a varios tipos clonales, lo cual sugiere no sólo la diseminación de una cepa resistente, sino también la diseminación horizontal de este mecanismo de resistencia entre clones diferentes.From 129 P. aeruginosa isolated at a health care centre located in Buenos Aires (Hospital "Eva Perón", 14% produced IMP-13. Although 18 isolates were metallo-beta-lactamases (MBL producers, only those isolates that displayed altered outer membrane protein profiles correlated with the resistant category according to CLSI or even Subcomisión de Antimicrobianos, SADEBAC, AAM. Phenotypic screening of metallo-beta-lactamases proved to be appropriate for detecting MBL producing isolates. IMP-13 producing isolates corresponded to at least five different clonal types, which not only suggests the dissemination of the resistant strain but also of the resistant marker.

    Full Text Available This research aims to explain the theoretical and clinical use of shock therapies in Argentine psychiatric field, particularly in the province of Buenos Aires between 1930 and 1970. It is argued that it is necessary to study the theoretical and clinical psychiatric work, in order to learn how psychiatrists interpreted mental pathology. Thus two distinct scenarios are analyzed: first academia, emphasizing on medical texts expressing discussions held at congresses, conferences, university chairs, and secondly in hospital settings, represented by a population of chronic patients in a hospital on the outskirts of the Capital Federal, the Esteves Hospital of Lomas de Zamora. The use of shock therapy in the hands of psychiatrists, changed the way of understanding madness and transformed the daily course of hospitals. Therefore, the presence of such therapies was relevant to legitimize the discipline, regardless of the “effectiveness” with patients.

  10. Deep-seated salt dissolution in the Delaware basin, Texas and New Mexico

    Anderson, R.Y.

    1981-01-01

    Patterns of salt dissolution in the Delaware Basin are related to the bedrock geometry and hydrology that developed following uplift, tilting, and erosion in the late Cenozoic, and the greatest volume of salt has been removed since that time. During the Permian, some salt was dissolved from the top of the Castile Formation before deposition of the Salado Formation and from the top of the Salado before deposition of the Rustler Formation. In addition, some salt dissolution occurred after the Permian and before the Cretaceous. Post-uplift surface dissolution has progressed across the Delaware Basin from south to north and west to east and generally down the regional dip. Deep-seated dissolution has occurred around the margin of the basin where the Capitan Limestone aquifer is in contact with the Permian evaporites and within the basin where selective dissolution in the lower Salado has undercut the overlying salt beds of the middle and upper Salado. Dissolution has not advanced down regional dip uniformly but has left outliers of salt and has progressed selectively into structurally predisposed areas. This selective advance has significance for the stability of the U.S. Department of Energy's Waste Isolation Pilot Plant (WIPP) site

    1993-07-01

    The Salado Two-Phase Flow Laboratory Program was established to address concerns regarding two-phase flow properties and to provide WIPP-specific, geologically consistent experimental data to develop more appropriate correlations for Salado rock to replace those currently used in Performance Assessment models. Researchers in Sandia's Fluid Flow and Transport Department originally identified and emphasized the need for laboratory measurements of Salado threshold pressure and relative permeability. The program expanded to include the measurement of capillary pressure, rock compressibility, porosity, and intrinsic permeability and the assessment of core damage. Sensitivity analyses identified the anhydrite interbed layers as the most likely path for the dissipation of waste-generated gas from waste-storage rooms because of their relatively high permeability. Due to this the program will initially focus on the anhydrite interbed material. The program may expand to include similar rock and flow measurements on other WIPP materials including impure halite, pure halite, and backfill and seal materials. This conceptual plan presents the scope, objectives, and historical documentation of the development of the Salado Two-Phase Flow Program through January 1993. Potential laboratory techniques for assessing core damage and measuring porosity, rock compressibility, capillary and threshold pressure, permeability as a function of stress, and relative permeability are discussed. Details of actual test designs, test procedures, and data analysis are not included in this report, but will be included in the Salado Two-Phase Flow Laboratory Program Test Plan pending the results of experimental and other scoping activities in FY93

    With the development of economy, the health of river ecosystem is severely threatened because of the increasing effects of human activities on river ecosystem. In this paper, the authors assessed the river ecosystem health in aspects of chemical integrity and biological integrity, using the criterion in water quality, nutrient, and benthic macroinvertebrates of 73 samples in Haihe River Basin. The research showed that the health condition of river ecosystem in Haihe River Basin was bad overall since the health situation of 72. 6% of the samples was "extremely bad". At the same time, the health situation in Haihe River Basin exhibited obvious regional gathering effect. We also found that the river water quality was closely related to human activities, and the eutrophication trend of water body was evident in Haihe River Basin. The biodiversity of the benthic animal was low and lack of clean species in the basin. The indicators such as ammonia nitrogen, total nitrogen and total phosphorus were the key factors that affected the river ecosystem health in Haihe River Basin, so the government should start to curb the deterioration of river ecosystem health by controlling these nutrients indicators. For river ecosystem health assessment, the multi-factors comprehensive evaluation method was superior to single-factor method.

    We characterized the infective and sporulation capacities of microbial consortia of arbuscular mycorrhizal fungi (AMF) native of Buenos Aires province (Argentina) and determined if some soil characteristics and mycorrhizal parameters could allow to select potentially beneficial inocula. Soil samples were selected from seven locations in Buenos Aires province all under agricultural (A) and pristine (P) conditions. The AMF were multiplied and mycorrhizal root colonization of trap plants was observed at 10 weeks of growth. Spore number in field was low; however, after multiplication spore density accounted for 80-1175 spores per 100g of soil. The principal component analysis showed that the P and Fe soil contents are the main modulators of infectivity and sporulation capacity. The mycorrhizal potential was determined in three locations, being high in Pristine Lobería and Agricultural Trenque Lauquen and low in Junín. Agricultural Lobería (AL) and Pristine Lobería (PL) inocula were selected and their efficiency was evaluated under controlled conditions. Even though shoot dry matter increases after inoculation was not significant (p>0.05) mycorrhizal response was greater than 40% for tomato and 25% for corn, particularly after inoculation with inocula from the agricultural management. These results could be associated to the incipient development of mycorrhizae in both species. Additional research should be conducted to further develop our findings in order to determine the factors involved in the selection of efficient inocula.

    As an important composition component of river ecosystems, river habitats must undergo quality assessment to potentially provide scientific basis for river ecological restoration. Substrate composition, habitat complexity, bank erosion degree, river meandering degree, human activity intensity, vegetation buffer width, water quality, and water condition were determined as indicators for river habitat assessment. The comprehensive habitat quality index (CHQI) was established for the Wei River Basin. In addition, the indicator values were determined on the basis of a field investigation at 12 national hydrological stations distributed across the Wei, Jing, and Beiluo Rivers. The analytic hierarchy process was used to determine the indicator weights and thus distinguish the relative importance of the assessment indicator system. Results indicated that the average CHQIs for the Wei, Jing, and Beiluo Rivers were 0.417, 0.508, and 0.304, respectively. The river habitat quality for the three rivers was well. As for the whole river basin, the river habitat quality for 25% of the cross section was very well, the other 25% was well, and the 50% remaining was in critical state. The river habitat quality of the Jing River was better than that of the Wei and Beiluo Rivers.

    Full Text Available En esta contribución indagamos en torno a políticas públicas para el espacio público que se desarrollan en el seno de los gobiernos de Viena y Buenos Aires. Específicamente, pretendemos: a describir los discursos vigentes sobre el espacio público, focalizándonos en relación a la noción de integración, y b analizar diversas intervenciones estatales en el espacio público orientadas -al menos explícitamente- a generar ciudades más inclusivas e integradas. A partir de un análisis sustentado fundamentalmente en fuentes secundarias, entendemos que a pesar de discursos en apariencia similares, se debería considerar que Viena y Buenos Aires inscriben su historia y devenir en contextos territoriales disímiles. Sin embargo, el proceso de globalización implica -entre otras cuestiones- una homogenización de los discursos a la vez que una relativa subestimación de los condicionantes locales. Estimar los mismos resulta indispensable para entender las implicaciones de esos discursos en la implementación de políticas públicas con efecto directo en el espacio público y sus usos. Una evaluación de las diferencias de las condiciones locales enriquece el análisis en torno a las intervenciones en el espacio público por parte de los gobiernos de ambas ciudades, permitiéndonos comprender la ambigüedad de las nociones y el riesgo de pérdida/cuestionamiento de derechos que implica esa ambigüedad -especialmente para los sectores sociales más vulnerables de la sociedad-.

Se postula que la pregunta por los usos cotidianos del espacio urbano por parte de residentes de un barrio o zona específica amplía las coordenadas en las cuales examinar el cruce entre espacio urbano y desigualdad social. Los hallazgos expuestos muestran que estos hogares por su localización residencial –resultado de una elección y de movilización de recursos–gozan de la centralidad, capaz de condensar accesibilidad al trabajo y al consumo y proximidad con los vínculos familiares. Se trabaja con un corpus de 40 entrevistas biográficas a jefes y jefas de hogares residentes en Caballito. ABSTRACT This article discusses the daily mobility, understood as social practice of shift that allows access to activities, people and places, of residents in Caballito, a neighborhood located in the geographical center of Buenos Aires city. It is postulated that the question of the everyday uses of urban space by residents of a neighborhood or specific area extends the coordinates in which to examine the intersection between urban space and social inequality. Exposed findings show that these homes on their residential location -the result of an election and mobilization of resources- enjoy centrality, capable of condensing accessibility to labor and consumption and proximity to family ties.

    Full Text Available At the end of nineteenth century, certain Argentinean doctors who taught medicine at the Universidad de Buenos Aires considered that students had to develop an integral knowledge able to outweigh the medicine subjects. Consequently, not only have they tried to inculcate this wide knowledge into the students -which included literature and art concepts- but have also promoted the advantages of the physical activity -derived from sports- as necessary to strengthen the students, allowing them to face such extensive career and, in this way, increase the feelings of friendship and brotherhood. In 1920, Bernardo Houssay, renowned Argentinean doctor and Nobel Prize winner (in 1947, again insisted on the need of an exhaustive education and a harmonious development for the medicine student, for which he suggested building a University campus in Buenos Aires. Therefore, this paper analyzes the attempts of training the students in different practices and widening their knowledge beyond the strictly medical concepts. It also looks into the different projects (political, social in connection with the purposes above mentioned which were supported during those years in Argentina.Hacia fines del siglo XIX, algunos médicos argentinos que enseñaban en la Facultad de Medicina de la Universidad de Buenos Aires entendían que los estudiantes y futuros médicos debían ser formados en un saber integral, que superara las materias clínicas. De este modo, intentaron inculcarles el conocimiento de las letras y el arte, pero también promovieron las ventajas del desarrollo físico, forjado en las prácticas deportivas, necesario para fortalecer a los alumnos ante una carrera de tal magnitud y para acrecentar los sentimientos de confraternidad y camaradería. Hacia la década de 1920, Bernardo Houssay, célebre médico argentino y ganador del premio Nobel (en 1947, volvía a insistir sobre la necesidad de una educación integral del estudiante de medicina y propon

    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.

    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.

    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.

    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.

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. Legionella pneumophila es un patógeno de NAC en nuestro medio, debe buscarse mejor, particularmente en pacientes graves, inmunodeprimidos y en fumadores con enfermedad pulmonar obstructiva crónica (EPOC.Legionnaires’ disease is a well recognized cause of community acquired pneumonia (CAP all around the world.

El primero abogó por un arte social que invitaba a accionar a los obreros. El segundo pretendió renovar la literatura con fines estéticos. Los de Florida expresaban su mirada a través del periódico Martín Fierro ; y los de Boedo lo hacían desde las revistas Los Pensadores y Claridad. Tribuna del pensamiento izquierdista . A su vez, el 30 de noviembre de 1930, el boedista Leónidas Barletta creó el Teatro del Pueblo, dando inicio al movimiento de teatros independientes en la ciudad.

    Results of the first stable isotopes analysis (δ""1"3C and δ"1"5N) of archaeological sites located in the southwest of the province of Buenos Aires (Argentina) are presented. Both the construction of an isotopic ecology and prehistoric human diets of the sector are explored. The isotopic ecology indicates diverse environments in which marine animals have enriched δ"1"3C col. values; while terrestrial species such as coypo, greater rhea and large-sized herbivores have the poorest values that are indistinguishable among the different taxa. Furthermore, ducks and a hairy armadillo showed intermediate values. Human isotopic values indicate a diet based on the consumption of meat. These proteins came predominantly from terrestrial animals complemented by marine resources. The local archaeological record is consistent with this information, as the main faunal resources are terrestrial species; nevertheless a scarce representation of marine fauna, mainly Otariids, is registered. In this paper we present the first isotopic values for the studied area and thus it is a preliminary contribution that must be further investigated with new samples

    Full Text Available This article analyses the connection between urban space and sexual diversity in two contemporary Brazilian short stories: “The triumph of hair”, by Aretusa Von, and “My darling Buenos Aires”, by Cíntia Moscovich. Both texts question the space/gender relation, as they accuse and subvert the gendered nature of geographic and discursive places. Besides this, they outline a type of queer space, by questioning compulsory heterosexuality and by deconstructing the binaries that hierarchize contemporary society.

    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

    2011-11-01

    Full Text Available In order to understand the debate between two thinkers considered to be Marxist, the current article propounds to situate them within a philosophical tradition represented by José Ortega y Gasset. This tradition met in an original way international and philosophical debates, and only drawing from that tradition it is possible to understand Manuel Sacristán’s proposal to put an end to the faculties of philosophy in 1968; to this suggestion Gustavo Bueno responded. The reconstruction of this debate allows to salvage a reflection on the philosophy of Ortega which enables original responses to the problem of the autonomy of philosophy and its relationship to other forms of knowledge. This reflection was critically updated restructured during the debate between both authors, though until now has gone relatively unnoticed.

    Full Text Available Canine brucellosis caused by Brucella canis is a disease of the reproductive tract that may cause miscarriage in females, infection of the sexual organs in males and infertility in both sexes. The prevalence of brucellosis in dogs is unknown and little has been done to control the disease, except in certain breeds and some commercial dog kennels. In the course of a free neuter program in Lomas de Zamora, Buenos Aires province, prevalence of antibodies to Brucella sp., bacteriological isolation and clinical observations were performed. Of 224 dogs studied, 33 (14.7% were found positive for the rapid slide agglutination test (RSAT, 24 (10.7% of which were confirmed by IELISA. 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. Debido a que los perros infectados permanecen bacteriémicos durante períodos prolongados, constituyen un riesgo para la salud pública.

    2015-12-01

    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.

Uno de ellos está sometido a agricultura permanente y el otro conserva un pastizal natural bajo pastoreo y quemas no programados. Este último sector presentó en promedio una densidad de 70.000 sem m-2 contra 36.720 sem m-2 en el primero. La representación de semillas de especies nativas se redujo notablemente en el ambiente agrícola. Stipa caudata con 31360 sem m-2 resultó la especie más abundante en el pastizal. En el ambiente de cultivo, su densidad se redujo a 9940 sem m-2 y fue superada por Chenopodium album con 10560 sem m-2. La similitud en la composición del banco fue de 55% en términos cualitativos y 27% en términos cuantitativos. Estos resultados evidencian que, en el área de estudio, el reemplazo del pastizal natural por agricultura reduce notoriamente las reservas de semillas y modifica la composición cualitativa y cuantitativa del banco con una elevada pérdida en la proporción de especies nativas.In order to evaluate the impact of agriculture on the potential flora of grasslands of the sierras of Azul (Buenos Aires Province, Argentina, the soil seed bank in the top 20 cm from two adjacent areas on the first foothill spurs were compared.

    Full Text Available Algunos estudios abordan los procesos urbanos que replantean la estructura, los usos del suelo y el paisaje de la ciudad; otros analizan los efectos de estos cambios en las condiciones de vida, las prácticas colectivas y las representaciones sociales. Este trabajo intenta ubicarse entre ambas perspectivas. Recorremos las intervenciones urbanas que reestructuraron un barrio de la ciudad de Buenos Aires entre 1998 y 2004, el barrio del Abasto. Esta transformación la impulsó el sector privado y consistió en el acondicionamiento de grandes emplazamientos urbanos para usos comerciales, residenciales y de entretenimiento. Investigamos los cambios urbanos desde las prácticas y representaciones cotidianas de los residentes de las Torres de Abasto, un grupo de personas que se mudó al barrio cuando ya había comenzado su reconversión. Analizamos los vínculos y las representaciones que se establecen en dicho complejo residencial y en el barrio que lo rodea.

    The purpose of the project described in this report was to prepare an operative tool for making decisions about the operation of the power system on the river Otra (Norway) with regard to how this operation might affect the various users of the river system. Above all this affects fish, outdoor life and esthetic values. The connection between water quality and volume of discharge has been examined in a sub project. How suitable parts of the river are as habitats for trout has been simulated on a computer. From field investigation it is concluded that near the Steinfoss power station the physical conditions for trout depend on the operation of the river system.

    The H-10 borehole complex, a group of three closely spaced boreholes, is located 3 1/2 miles southeast of the proposed Waste Isolation Pilot Plant site in west-central Lea County, New Mexico. The geological data presented in this report are part of a site-characterization study for the possible storage of defense-associated radioactive wastes within salt beds of the Salado Formation of Permian age. Each borehole was designated to penetrate a distinct water-bearing zone: H-10a (total depth 1 ,318 feet) was completed just below the Magenta Dolomite Member of the Rustler Formation of Permian age; H-10b (total depth 1 ,398 feet) was completed just below the Culebra Dolomite Member of the Rustler Formation; and H-10c (total depth 1,538 feet) was completed below the Rustler Formation-Salado Formation contact. The geologic units penetrated in borehole H-10c are surficial alluvium and eolian sand of Holocene age (0-5 feet); the Mescalero caliche (5-9 feet) and the Gatuna Formation (9-90 feet) of Pleistocene age; formation in the Dockum Group (Chinle Formation, 90-482 feet and Santa Rosa Sandstone, 482-658 feet) of Late Triassic age; and the Dewey Lake Red Beds (658-1,204 feet), the Rustler Formation (1,204-1,501 feet), and part of the Salado Formation (1,501-1,538 feet), all of Permian age. The sections of the Rustler and Salado Formations penetrated by borehole H-10c are complete and contain little or no evidence of dissolution of halite and associated rocks, indicating that the eastward-moving dissolution on top of the Salado, found just to the west of the WIPP site, has not reached the H-10 site.

    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.

    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.

It considers the estimation of expenditure, identifying the actors who execute and implement programs that allow you to have a reference to the relevance of the issue tacked by the provincial agenda. The work was done from the budgetary information produced by the General accounting of BAP, which is dependant of the Ministry of Finance, through classifiers used by the province. Firstly it presents the estimation and evolution of environmental expense according to the provincial classification, then it widens with the Classification of Environmental Protection Activities (CEPA 2000. Secondly it characterizes state actors that implement environmental expense and the financed program types. Finally it is presented some preliminary conclusions. The central input refers that environmental public expenses, later in one decade of increase after politic, social and economic crisis in 2001, does not achieve the convertibility participation levels. Also it emphasizes in the water and sanitation engineering; it has a strong component of participation of centralized agencies in detriment of those that agglutinates the main environmental functions; it is not observed instances of civil society participation in execution; and it adjudge a low relevance to the promotion and education activities in environmental matters.

    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”.

    Exposure to increased levels of ambient air particulate matter (PM) is associated with increased cardiopulmonary morbidity and mortality. Its association with adverse health effects and the still unclear mechanisms of action are of concern worldwide. Our objective was to analyze air PM from downtown Buenos Aires (UAP-BA), and evaluate its biological impact on normal airways. We studied the inflammatory response to intranasal instillation of UAP-BA in a short-term-exposure mouse model. We analyzed UAP-BA morphology by scanning electron microscopy and characterized particle chemical composition by energy dispersive X-ray analysis and capillary gas chromatography. We evaluated lung changes by histomorphometry and histochemical methods. Regarding size, surface area and distribution, UAP-BA proved to be small spherical ultrafine particles: free, in clusters and associated to a matrix. The particles contained polycyclic aromatic hydrocarbons, polychlorinated biphenyls and almost no metal traces. Histologically, UAP-BA induced the recruitment of phagocytes, a reduction in air spaces, an increase in mucous PAS positive cells and weak incomplete elastic fiber network. Our results demonstrate that UAP-BA causes adverse biological effects on the respiratory tract generating inflammation that, in turn, may cause tissue injury or organ dysfunction and may contribute to the pathogenesis of lung diseases

    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.

    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

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 At Lidar Division of CEILAP (CITEDEF-CONICET a multiwavelength Raman-Rayleigh lidar optimized to measure the atmospheric boundary layer is being operated. This instrument is used for monitoring important aerosol intrusion events in Buenos Aires, such as the arrival of volcanic ashes from the Chaitén volcano eruption on May 2008. That was the first monitoring of volcanic ash with lidar in Argentina. In this event several volcanic ash plumes with high aerosol optical thickness were detected in the free atmosphere, affecting the visibility, surface radiation and therefore, the ABL evolution. In this work, the impact of ashes in entrainment flux ratio is studied. This parameter is obtained from the atmospheric boundary layer height and entrainment zone thickness using algorithms based on covariance wavelet transform.

    Personal correspondence written by Prof. Felix Krueger from Argentina in 1906-1907 to his teacher and mentor Wilhelm Wundt in Leipzig is situated in the historical context of the theoretical debates taking place at the University of Buenos Aires at the beginning of the 20th century. A critical survey of the transatlantic migration of psychological theories and their reception in Argentina raises the broader issues of the nature of the cultural and social roots of local interpretations induced by the circulation of theories across national fields of scientific inquiry. It is argued that national intellectual fields and the historicity of their categories of interpretation mediate in the foreign trade of theories.

The results showed that the mass concentrations of NO2- -N, NO3- -N, NH4+ -N and TN in the Gonghu Bay were lower than those of the Yangtze River and Wangyu River during the 2 water transfer processes. However, there was higher level of DON content in the Gonghu Bay than that of the Yangtze River and Wangyu River. The percentages of various N species showed that NO3- -N was the major N species in the Yangtze River and Wangyu River during the 2 water transfer processes. TP contents in samples collected from the Yangtze River displayed a constant trend compared with the Wangyu River. However, the percentages of various P species were different with each other during the 2 water transfer processes. Mass concentrations of DON and TP in surface water in August were higher than those in December and the contents of NO3- -N and TDP were lower in August than those in December. In general, NO3- -N and TPP were the main N and P species in Wangyu River from the Yangtze River. NO3- -N, PO4(3-) -P and TPP were the main N and P species in Gonghu Bay from Wangyu River during the 2 water transfer processes.

    The Department of Civil and Environmental Engineering, Outdoor Recreation, and Parks and Recreation programs at Utah State University (USU) have partnered to offer a new, unique river-based experiential learning opportunity for undergraduates called the Bear River Fellows Program. The program allows incoming freshmen Fellows to experience a river first hand during a 5-day/4-night river trip on the nearby Bear River two weeks before the start of their first Fall semester. As part of the program, Fellows will navigate the Bear River in canoes, camp along the banks, interact with local water and environmental managers, collect channel cross section, stream flow, vegetation cover, and topological complexity data, meet other incoming freshmen, interact with faculty and graduate students, develop boating and leadership skills, problem solve, and participate as full members of the trip team. Subsequently, Fellows will get paid as undergraduate researchers during their Fall and Spring Freshman semesters to analyze, synthesize, and present the field data they collect. The program is a collaborative effort between two USU academic units and the (non-academic) division of Student Services and supports a larger National Science Foundation funded environmental modelling and management project for the lower Bear River, Utah watershed. We have advertised the program via Facebook and emails to incoming USU freshmen, received 35 applications (60% women), and accepted 5 Fellows into the program (3 female and 2 male). The river trip departs August 14, 2012. The poster will overview the Bear River Fellows Program and present qualitative and preliminary outcomes emerging from the trip and Fellows' work through the Fall semester with the field data they collect. We will also undertake more rigorous and longer longitudinal quantitative evaluation of Program outcomes (for example, in problem-solving and leadership) both in Spring 2013 and in subsequent 2013 and 2014 offerings of the

    Full Text Available In the world, river basins often interwoven into two or more states or prefectures and because of that, disputes over water are common. Nevertheless, not all shared river basins are associated with water conflicts. Rivers in Japan and Malaysia play a significant role in regional economic development. They also play a significant role as water sources for industrial, domestic, agricultural, aquaculture, hydroelectric power generation, and the environment. The research aim is to determine the similarities and differences between the Sagami and Muda River Basins in order to have a better understanding of the governance needed for effectively implementing the lessons drawn from the Sagami River Basin for improving the management of the Muda River Basin in Malaysia. This research adopts qualitative and quantitative approaches. Semi-structured interviews were held with the key stakeholders from both basins and show that Japan has endeavored to present policy efforts to accommodate the innovative approaches in the management of their water resources, including the establishment of a river basin council. In Malaysia, there is little or no stakeholder involvement in the Muda River Basin, and the water resource management is not holistic and is not integrated as it should be. Besides that, there is little or no Integrated Resources Water Management, a pre-requisite for sustainable water resources. The results from this comparative study concluded that full support and participation from public stakeholders (meaning the non-government and non-private sector stakeholders is vital for achieving sustainable water use in the Muda River Basin. Integrated Water Resources Management (IWRM approaches such as the introduction of payments for ecosystems services and the development of river basin organization in the Muda River Basin should take place in the spirit of political willingness.

Particularly, this research focuses on four archaeological assemblages from the Paso Otero archaeological locality (Buenos Aires Province, Argentina. The study of diagenetic parameters such as porosity, crystallinity (IRSF, diagenetic carbonate content (C/P, calcite, protein content (%N and histology were applied to bone assemblages of archaeological sites recorded in «A» buried soil horizons located in ancient flood plains in the middle basin of the Quequén Grande River. The chronological span includes the late Pleistocene and the beginning of the late Holocene. The analysis of bone microstructure indicates a pattero of differential bone preservation even when the archaeological assemblages come from quite similar environmental depositional settings. Consequently, it is remarkable that every site has undergone a very particular taphonomic history regarding post-burial processes. The possible causes of theses differences are explored and discussed.El objetivo de este trabajo es el de determinar el grado de alteración diagenética de cuatro conjuntos óseos provenientes de tres sitios de la localidad arqueológica Paso Otero, ubicada en la cuenca media del río Quequén Grande (Provincia de Buenos Aires, Argentina.

    Rivers are inherently dynamic water systems involving complex interactions among hydrodynamics, morphology and ecology. In many deltas around the world lowland rivers are intensively managed to meet objectives like safety, navigation, hydropower and water supply. With the increasing pressure of growing population and climate change it will become even more challenging to reach or maintain these objectives and probably also more demanding from a management point of view. In the meantime there is a growing awareness that rivers are natural systems and that, rather than further regulation works, the dynamic natural processes should be better utilized (or restored) to reach the multifunctional objectives. Currently many integrated river management projects are initiated all over the world, in large rivers as well as streams. Examples of large scale projects in the Netherlands are 'Room for the River' (Rhine), the 'Maaswerken' (Meuse), the Deltaprogramme and projects originating from the European Water Framework Directive (WFD). These projects include innovative measures executed never before on this scale and include for example longitudinal training dams, side channels, removal of bank protection, remeandering of streams, dredging/nourishment and floodplain rehabilitation. Although estimates have been made on the effects of these measures for many of the individual projects, the overall effects on the various management objectives remains uncertain, especially if all projects are considered in connection. For all stakeholders with vested interests in the river system it is important to know how that system evolves at intermediate and longer time scales (10 to 100 years) and what the consequences will be for the various river functions. If the total, integrated response of the system can be predicted, the system may be managed in a more effective way, making optimum use of natural processes. In this way, maintenance costs may be reduced, the system remains more natural

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 Available In may 1740, Jesuits Querini and Strobel started the mission “Nuestra Señora de la Purísima Concepción de los Indios Pampas”, at the mouth of the Salado River in the Argentinean pampas, thus beginning an ambitious evangelizer project for the indigenous groups that inhabited in the Pampa and Patagonia lands. Within a few years, the new town had to be moved to a nearby site, where settled until 1753. This paper presents the analysis of the document database collected in the context of archaeological investigations that we began in 1998, focused on aspects related to the mission geographical environment, its initial population, buildings and layout, as well as the information about the current location of the two settlements that consecutively formed it.

    In February 2017, the Grand River Dam Authority filed to relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission. The predominant feature of the Pensacola Hydroelectric Project is Pensacola Dam, which impounds Grand Lake O’ the Cherokees (locally called Grand Lake) in northeastern Oklahoma. Identification of information gaps and assessment of project effects on stakeholders are central aspects of the Federal Energy Regulatory Commission relicensing process. Some upstream stakeholders have expressed concerns about the dynamics of sedimentation and flood flows in the transition zone between major rivers and Grand Lake O’ the Cherokees. To relicense the Pensacola Hydroelectric Project with the Federal Energy Regulatory Commission, the hydraulic models for these rivers require high-resolution bathymetric data along the river channels. In support of the Federal Energy Regulatory Commission relicensing process, the U.S. Geological Survey, in cooperation with the Grand River Dam Authority, performed bathymetric surveys of (1) the Neosho River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, (2) the Spring River from the Oklahoma border to the U.S. Highway 60 bridge at Twin Bridges State Park, and (3) the Elk River from Noel, Missouri, to the Oklahoma State Highway 10 bridge near Grove, Oklahoma. The Neosho River and Spring River bathymetric surveys were performed from October 26 to December 14, 2016; the Elk River bathymetric survey was performed from February 27 to March 21, 2017. Only areas inundated during those periods were surveyed.The bathymetric surveys covered a total distance of about 76 river miles and a total area of about 5 square miles. Greater than 1.4 million bathymetric-survey data points were used in the computation and interpolation of bathymetric-survey digital elevation models and derived contours at 1-foot (ft) intervals.

    River classification is very important to know the river characteristic in study areas, where this database can help to understand the behaviour of the river. This article discusses about river classification using Chemometrics techniques in mainstream of Pahang River. Based on river survey, GIS and Remote Sensing database, the chemometric analysis techniques have been used to identify the cluster on the Pahang River using Hierarchical Agglomerative Cluster Analysis (HACA). Calibration and validation process using Discriminant Analysis (DA) has been used to confirm the HACA result. Principal Component Analysis (PCA) study to see the strong coefficient where the Pahang River has been classed. The results indicated the main of Pahang River has been classed to three main clusters as upstream, middle stream and downstream. Base on DA analysis, the calibration and validation model shows 100 % convinced. While the PCA indicates there are three variables that have a significant correlation, domination slope with R"2 0.796, L/D ratio with R"2 -0868 and sinuosity with R"2 0.557. Map of the river classification with moving class also was produced. Where the green colour considered in valley erosion zone, yellow in a low terrace of land near the channels and red colour class in flood plain and valley deposition zone. From this result, the basic information can be produced to understand the characteristics of the main Pahang River. This result is important to local authorities to make decisions according to the cluster or guidelines for future study in Pahang River, Malaysia specifically and for Tropical River generally. The research findings are important to local authorities by providing basic data as a guidelines to the integrated river management at Pahang River, and Tropical River in general. (author)

  6. 40Ar/ 39Ar dating of Late Permian evaporites, southeastern New Mexico, USA

    40Ar/ 39Ar dating of the potassium-magnesium sulfate mineral langbeinite from Permian evaporites of the Salado formation near Carlsbad, New Mexico, provides quantitative evidence that some salts in these deposits have not recrystallized for 251 Myr since deposition. Survival of Permian salts supports the possibility that Bacillus bacteria recovered from nearby halite was isolated in a closed system and represents a sample of uncontaminated Permian life. Local recrystallization of langbeinite and other nearby minerals is also indicated by the dating, suggesting both the need and the opportunity to document closed system behavior more rigorously. The shoaling and desiccation event recorded by the Salado formation began at least 1 Myr before the Permian-Triassic boundary. Temporal correlation of the Salado with the Zechstein evaporites of north-central Europe supports previously inferred regression models for the origin of these deposits. Significant paleoenvironmental change at the Permian-Triassic boundary thus occurred on a time scale more protracted than that implied by geologically instantaneous events such as bolide impacts.

    The proposed site for the U.S. Department of Energy's Waste Isolation Pilot Plant (WIPP) is in the Los Medanos area located about 40 km east of Carlsbad, in eastern Eddy County, NM. Geohydrologic data have been collected from this area since 1972, and the data will be used as part of a study evaluating the feasibility of storing defense-associated transuranic wastes in bedded salt at a depth of 655 m. The salt beds are within the Salado Formation of Permian age. The study presented includes the determination of ground-water flow boundaries; potentiometric heads; ground-water chemistry; and hydraulic properties through pump, slug, pressure-pulse, and tracer tests. Data collected during drilling and testing 30 hydrologic holes have indicated three zones above the Salado Formation that could potentially transport wastes to the biosphere if the proposed facility is breached. These zones include the Magenta and Culebra Dolomite members of the Rustler Formation and the contact zone between the Rustler and Salado formations

    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.

More specifically, this study characterizes and describes the theoretical trends of the subject Educational Policy contents in the 50s of the last century in the Buenos Aires and La Plata Federal Universities. 46 programs were analyzed in the period 1917-1959, as well as the bibliography and theoretical background linked to the professors who were responsible for the subject. Surveying professors’ biographies, it was observed that in the period prior to the institutionalization of this field, the debate focused on the positivism or anti-positivism theoretical trends. Later on, the theoretical trends that permeated the programs from 1953 to 1954 had more distinct shades of positivism and anti-positivism than those of the beginning of the century, and three axes were observed: the national tradition, the pedagogical progressivism and the Spanish Krausism.

    2005-12-01

    Full Text Available A river that preserves a simplified and attractive form may nevertheless have lost function. Loss of function in these rivers can occur because hydrologic and geomorphic processes no longer create and maintain the habitat and natural disturbance regimes necessary for ecosystem integrity. Recognition of compromised river function is particularly important in the context of river restoration, in which the public perception of a river's condition often drives the decision to undertake restoration as well as the decision about what type of restoration should be attempted. Determining the degree to which a river has been altered from its reference condition requires a knowledge of historical land use and the associated effects on rivers. Rivers of the Front Range of the Colorado Rocky Mountains in the United States are used to illustrate how historical land uses such as beaver trapping, placer mining, tie drives, flow regulation, and the construction of transportation corridors continue to affect contemporary river characteristics. Ignorance of regional land use and river history can lead to restoration that sets unrealistic goals because it is based on incorrect assumptions about a river's reference condition or about the influence of persistent land-use effects.

Se determinaron 17 marcadores Y-STRs en 85 donantes no emparentados. Un total de 85 haplotipos únicos fueron observados. La diversidad haplotípica  fue de 1,000+/-0.0018, y la diversidad genética media de 0,680+/-0,095.

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.
