Dicho sitio se encuentra localizado en el valle del río Atuel (Mendoza, Argentina. El trabajo intenta ajustar el conocimiento de la dispersión agrícola prehispánica utilizando información en sectores no estudiado previamente. Se definen dos pulsos discontinuos en el depósito de La Olla, el más antiguo en torno a 1900 años 14C AP y el otro entre 700 y 400 años 14C AP. El análisis confirma una estabilidad en la subsistencia y dieta humana basada en recursos de bajo retorno energético compuesta entre otros por algarrobo y animales pequeños como peces y dasipódidos. Por otra parte, se evidencian cambios en la organización tecnológica que son interpretados en términos de movilidad y rangos de acción. De este modo, el sitio La Olla muestra cómo se manifestarían ocupaciones penecontemporáneas y espacialmente cercanas a los Contextos Atuel I y Atuel II. Abstract  This paper presents the archaeological record of La Olla site, located in the Atuel river valley (Mendoza, Argentina.

    The Quaternary evolution of the Payenia Basaltic Province (PBP) in southern Mendoza, Argentina has been investigated using a multi-dating approach in combination with pre-exiting geochemical data. This basaltic province covers an area of approximately 40000 km2 and is mainly characterised by backarc volcanism. In the current investigation nine new radiometric ages obtained using surface exposure, 40Ar/39Ar and thermoluminescence dating are presented. Six ages correspond to the late Pleistocene and three to the Holocene. The surface exposure ages obtained using cosmogenic 3He and 21Ne are in good agreement with previous publications and confidently suggest that part of this basaltic province was active at least 4000 years ago (taking a conservative approach). In addition, we combined the available geochronological and geochemical data to reconstruct the Quaternary evolution of this basaltic province. This approach was used to create maps of geospatial distribution of trace-element ratios to determine geochemical changes during the Pleistocene. Employing this method it is evident that two geochemical distinct types of magma were erupting at the same time interval within the PBP. In the north eastern part (Nevado volcanic field) of the PBP an arc-like signature is evident, while in the southern part (Río Colorado volcanic field) of the same basaltic province an Ocean Island Basalt (OIB) signature is evident. The arc-like signature in the north eastern part of the PBP, decreased during the Pleistocene in a north-west direction indicated by a reduction in Ba/La and La/Ta in the Nevado and Llancanelo volcanic field. The Holocene volcanism is restricted to the western side of the Payún Matrú volcanic field and is dominated by OIB-like signatures such as high Ta/Hf and low Ba/La and La/Ta. This contribution presents new geochronology for the PBP and confirms that two different types of volcanism occurred simultaneously during the Pleistocene, while the Holocene

    Full Text Available The landscape is a perception of the agroecosystem valued as aesthetic, cultural, recreational and touristic, for conservation, among others. It is considered an environmental service and cultural heritage according to the International UN Conference 1972 (Paris, France. The agroecosystem of Mendoza's Northern Oasis creates a landscape with the presence of vineyards framed by the Andes, which is a scenic resource characterized as an environmental cultural service. The disordered process of urban growth in North of Mendoza, threatens the provision of the mentioned service. In this paper, a qualitative and a quantitative assessment aim to characterize the perceptions of urban residents on the vineyards landscape. Two methodologies were applied: expert opinion through focus groups and survey data collection. By working with focus groups, positive impacts of this kind of landscape were recognized. In the 638 surveys made in the urban area of Mendoza, a six landscape images valuation was requested (with a score of 1 to 10, where 10 is the maximum. The highest average scores were for the view of Aconcagua, secondly the agricultural landscape with vineyards and mountains and thirdly another view of vineyards in the North Oasis.

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

    Knowledge of the chemical composition of wine and its association with the grape variety/cultivar is of paramount importance in oenology and a necessary tool for marketing. Phenolic compounds are very important quality parameters of wines because of their impact on colour, taste and health properties. The aim of the present work was to study and describe the non-flavonoid and flavonoid composition of wines from the principal red grape varieties cultivated in Mendoza (Argentina). Sixty phenolic compounds, including phenolic acids/derivatives, stilbenes, anthocyanins, flavanols, flavonols and dihydroflavonols, were identified and quantified using high-performance liquid chromatography with diode array detection coupled with electrospray ionisation mass spectrometry (HPLC-DAD/ESI-MS). Marked quantitative differences could be seen in the phenolic profile among varieties, especially in stilbenes, acylated anthocyanins and other flavonoids. The polyphenolic content of Malbec wines was higher compared with the other red varieties. Dihydroflavonols represent a significant finding from the chemotaxonomic point of view, especially for Malbec variety. This is the first report on the individual phenolic composition of red wines from Mendoza (Argentina) and suggests that anthocyanins, flavanols and phenolic acids exert a great influence on cultivar-based differentiation.

We had used on surface dates because in this level exist to big amount of information, practically it is possible to get its measures continuously; in addition it is the level that data of damages are registered that the hail precipitation produces. The decision to use the level of 500 mb, it must to that it is the height in which the upset one of the air circulation takes place from the Pacific to Mendoza, who produces important changes and instability in the atmosphere of Mendoza, these data were obtained from the radiosonde of Santo Domingo in Santiago (Chile) and El Plumerillo (Mendoza). In the program is integrated the different indices and models obtained in ours works from investigation on the subject of last the five years. Since the October of 2004 to April of 2009 the values have been taken from the variables mentioned every day, hourly during the fight campaigns antihail (October-April). The results have integrated in the program INCAS, whom it is due to enter the surface variables: Temperature in °C, the dew point in °C, the atmospheric pressure in mb., the index of ultraviolet solar radiation, the direction and wind speed; whereas the variables of the level of 500 are due to introduce mb: height of the level of 500 mb in meters, temperature of the level in °C, the direction and wind speed to that height. From the process of these variables the type of convective process is obtained like exit of the program , that is more probable that it appears in Mendoza for these atmospheric conditions; the thresholds that trigger to the stormy processes and their possible severity. This year software was validated in his first version, obtaining itself very good results.

    New findings of dinosaur ichnites from Agua del Choique section (Mendoza Province, Argentina) provides ichnological and anatomical information about the Cretaceous sauropods and theropods. Around 330 tracks distributed in six footprint levels were identified in this area, one of most important of South America. Two ichnocenoses are located in different paleoenvironmental contexts. In the Anacleto Formation (early Campanian) around 20 titanosaurian tracks were found in floodplain and ephemeral channel deposits. Herein, one pes track shows three claw impressions and this is congruent to two new titanosaur specimens recently discovered in Mendoza Province that have articulated and complete pedes. In this context, for the first time to titanosaurs, ichnological evidences are supported by skeletal elements. In the Loncoche Formation (late Campanian-early Maastrichtian) titanosaurian tracks of Titanopodus mendozensis are abundant (around 310 tracks) and were produced by titanosaurs that walked in a very wet substrate of tidally dominated deltas related with the first Atlantic transgression for northern Patagonia. In this facies association, three different trydactl tracks indicate the presence of small theropods (1-2 m long), expanding the knowledge about the faunistic components that lived in these marine marginal environments.

    Full Text Available Lately, several authors have been analyzing the changes in rural areas triggered by globalization. The concepts of new rurality and pluriactivity have allowed progress along these lines, highlighting the new difficulties facing the most vulnerable sectors. This study explores the transformation of peripheral rural territories in Mendoza (Argentina, particularly those that have been thought of as isolated and traditional. This research develops from a case study, combines quantitative and qualitative methods, and takes the production undertakings happening in those lands as units of analysis. Production and economic situations of the past are compared to those in the present. The tendency toward pluriactivity is here considered as a response to the new conditions, and also as an expression of the process of articulation with the capitalist system.

    Full Text Available The Quaternary volcanic province of Payenia is located in southern Mendoza and northern Neuquén provinces of Argentina and is characterized by a dominant basaltic composition. The volcanic province covers an area larger than 40,000 km2 and its origin and evolution has been the center of several studies. In this study we analyzed gravity data together with more accurate volcanic volumes calculations in order to investigate the subsurface structure of the Payenia volcanic province. The volume of material was calculated using digital elevation models and geographic information system (GIS techniques to estimate the volume of material erupted and then, with those values, make an estimation of the intrusive material that could be located within the crust. The results of the calculations were compared with different 2D-sections constructed to model the gravity data and compare with the observed satellite gravity. After evaluating different models which have been generated to match both: the observed gravity data and the subsurface material calculated, we discuss those that best fit with observation. The results clearly indicate that the lithosphere is attenuated below the region.

    A shallow multichannel seismic survey reaching depths of 700/800 m was performed for the first time in the Llancanelo Lake region (Southern Mendoza Province, Argentina), in order to depict the major Neogene sedimentary-volcanic sequences that form the final infilling of the tectonic-volcanic basin where the lake is located. The seismic survey advances on the results of previous geoelectric and electromagnetic surveys carried out at early stages of the research that reached the uppermost 80-100 m of the sequences (Quaternary), and therefore they go deeper in the subsoil. All the surveys were supported by surface and subsoil geological observations. After explaining the details of the performed seismic methodology, the obtained results are discussed, which indicate the presence of three major sedimentary units with increasing volcanic (basaltic layers) intercalations with depth, that accommodate to the geometry of the depocenter. The entire sequence encompasses most of the Neogene. This research sets the methodological basis for future, more detailed shallow seismic surveys in the region.

    The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large area behind the active Andean volcanic arc. Here we focus on the northern Llancanelo volcanic field, particularly in Las Bombas volcano. Las Bombas volcano is an eroded, but still recognizable, scoria cone located in a circular depression surrounded by a basaltic lava flow, suggesting that Las Bombas volcano was there when the lava flow field formed and, therefore, the lava flow engulfed it completely. While this explanation seems reasonable, the common presence of similar landforms in this part of the field justifies the need to establish correctly the stratigraphic relationship between lava flow fields and these circular depressions. The main purpose of this research is to investigate Las Bombas volcano 3D subsurface architecture by means of geophysical methods. We carried out a paleomagnetic study and detailed topographic, magnetic and gravimetric land surveys. Magnetic anomalies of normal and reverse polarity and paleomagnetic results point to the occurrence of two different volcanic episodes. A circular low Bouguer anomaly was detected beneath Las Bombas scoria cone indicating the existence of a mass deficit. A 3D forward gravity model was constructed, which suggests that the mass deficit would be related to the presence of fracture zones below Las Bombas volcano cone, due to sudden degassing of younger magma beneath it, or to a single phreatomagmatic explosion. Our results provide new and detailed information about Las Bombas volcano subsurface architecture.

Esta situación es particularmente importante en el caso de los edificios construidos sobresuelo en climas con temperaturas diarias y estacionales muy variables. En el caso de que la arquitectura no provea la respuesta adecuada, indefectiblemente se recurre al consumo de energía auxiliar. La bodega S.A., ubicada en Mendoza, Argentina, consume energía auxiliar equivalente a 2.500 kW por año. Dicha bodega sobresuelo presenta dos tipos de envolvente vertical: una tradicional en adobe (λ = 0.81W/mK y otra contemporánea en chapa galvanizada sin aislación (λ = 45 W/mK. El objetivo de este trabajo es analizar los aspectos de materialidad, inercia térmica e intercambio de flujos energéticos de envolventes tradicionales y contemporáneas y, comparar los resultados obtenidos con un caso teórico de bodega subterránea. Entre los resultados obtenidos se observa que la envolvente tradicional mantiene las temperaturas interiores entre 8,5 ºC y 10 ºC por debajo de las temperaturas exteriores, mientras que los nuevos espacios con envolventes contemporáneas lo hacen solamente 3 ºC a 5 ºC por debajo de las temperaturas exteriores. En el caso de una bodega subterránea, las temperaturas estarían estables durante el año en 16,5 ºC; esto es, en verano, 20 ºC por debajo de las temperaturas exteriores.

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.

    The cat, considered the main reservoir of Microsporum canis, lives in urban areas, and also plays an important role in the emergence of dermatomycoses. To determine and analyse the frequency of zoonotic dermatophytes in a sample of cats in an urban area of the Gran Mendoza region. The animals selected were household cats and cats less than one year old that came from shelters and kennels from urban areas in the Gran Mendoza region. A total of 45 samples from cats with and without dermatological lesions were analysed. These samples were collected through skin scraping, hair removal and Mackenzie brush, respectively. Direct observation was made with KOH and glycerol after heat exposure. Samples were cultured on Sabouraud and Lactrimel agar slants with chloramphenicol and cycloheximide for 30 days. The frequency of dermatophytes isolated in this preliminary study was 13.3%. There were not statistically significant differences by source, age, sex, race or dermatological condition. Zoonotic dermatophytes were found in 2 household cats out of the 21 that had direct contact with children or the elderly. M. canis was isolated in 83.3% cases. The frequency of isolation of zoonotic dermatophytes in the sample of cats in an urban area of the Gran Mendoza region was 13.3%, a value higher than expected. M. canis was the most isolated species.

    In the semi-arid high Andes of Argentina and Chile, rock glaciers are more frequent and often larger than glaciers. Aridity and high solar radiation hamper the development of large glaciers, favour permafrost conditions and the generation of rock glaciers. One of the few rock glaciers that have been studied in more detail since more than 20 years is located in the Cordon del Plata range about 60 km west of Mendoza, Argentina. The Morenas Coloradas rock glacier in the Rio Vallecitos catchment can be described as a multilobe, multiunit, multiroot and multipart rock glacier. It is a complex, transitional landform composed of a high altitude glaciated zone, which transforms into a debris covered glacier with thermokarst phenomena followed by various active rock glacier lobes and subsequently, inactive and relict lobes in the lower sections. Its total length is about 5 km. Complex transitional landforms between debris covered glaciers and rock glaciers are frequently observed in semi-arid mountain environments with high sediment production in periglacial areas like the Andes of Argentina but can be found also in other similar mountain ranges like for example Pamir, or Karakorum. However, the evolution and internal characteristics of such landforms are often unknown. Glacial and periglacial landforms of this size represent important water stores that play an essential role in water management and agriculture in the foreland of the Andes of Mendoza. In February 2008 subsurface conditions were investigated at three different altitudes using geophysical methods (ground penetrating radar, electric resistivity tomography). Complemented by digital geomorphological mapping we analyse the complex rock glacier ensemble, to gain insight into landform evolution, sediment flow structures and internal characteristics (permafrost occurrence, active layer depths, ice content, possible ice origin). Geophysical surveying at Morenas Coloradas clearly indicates the existence of frozen

    Full Text Available During the last decade, the Deseadan (late Oligocene Quebrada Fiera locality, Mendoza Province, Argentina, has provided a large amount of mammal remains. Taxonomic studies have shown the presence of faunal elements common with other Deseadan associations from Patagonia and lower latitudes (Salla, Bolivia, as well as endemic taxa of different groups of mammals (Notohippidae, Leontiniidae, Homalodotheriidae, Hegetotheriidae, and Metatheria and even a gastropod. In this work, we present a taxonomic and phylogenetic analysis of a set of postcranial fossils of three families of the suborder Toxodontia (Notoungulata. The postcranial elements are assigned to taxa previously recognized at Quebrada Fiera, such as the leontiniid Gualta cuyana and the homalodotheriid Asmodeus petrasnerus, but also to the family Toxodontidae that is represented by Proadinotherium sp. and another larger toxodontid; a few dental remains of Proadinotherium are also included as this is the first time that toxodontids from Quebrada Fiera are described. In the case of A. petrasnerus, an almost complete calcaneum allows us to expand the diagnosis of this taxon. The bones assigned to G. cuyana enlarge the anatomical knowledge of this species. In turn, the presence of the genus Proadinotherium extends its geographic distribution in Argentina and adds to the extra-Patagonian record of P. saltoni from Salla, Bolivia. Phylogenetic results do not differ much from previous analyses using postcranial characters, and the obtained consensus trees show low node supports. The various phylogenetic analyses performed here provide a more robust framework to interpret the relationships of the studied taxa.

  1. Chronology of Late Pleistocene glacier advances in the Rı´o Mendoza Valley, Argentina

    Espizua, Lydia E.

    1999-10-01

    The Rı´o Mendoza valley at 33°S latitude has been repeatedly invaded by glaciers during the Late Pleistocene. Relative-age criteria, U-series ages, and thermoluminescense dating, permitted the glacial deposits to be separated into three mappable units, each less extensive than its predecessor, designed from oldest to youngest, Penitentes, Horcones and Almacenes drifts. Previous studies have shown that during the Penitentes advance the glacier system terminated at 2500 m, while during the subsequent Horcones advance, ice terminated at 2750 m and the Almacenes moraine reached 3250 m. A travertine layer overlying Penitentes till yielded 230Th/ 232Th ages of 38,300±5300, 24,200±2000 and 22,800±3100 yr B.P. This study focuses on dating interstadial sediments in the upper Rı´o Mendoza valley in order to constrain the ages of the drifts. A date was obtained from a composite stratigraphic profile based on exposures along the east side of the Rı´o de los Horcones Inferior valley, a tributary of the Rı´o de las Cuevas valley, which includes the Penitentes and Horcones tills separated by nonglacial sediments (silt, fine sand and clay), and are interpreted as representing the Penitentes-Horcones nonglacial interval. The fine quartz grains (4-11 μm) of these sediments were TL dated as 31,000±3100 yr. All these dates, which are minimum ages for the underlying Penitentes till, imply that the Penitentes ice advanced prior to the last glacial maximum and sometime before ca. 40,000 years ago. A minimum date for Horcones till comes from an exposure on the east side of the Rı´o de los Horcones Inferior valley where the Horcones and Almacenes tills are separated by sediments of nonglacial origin. The fine quartz grains (4-11 μm) of these sediments have been dated by TL as 15,000±2100 years ago. Almacenes till is inferred to represent a standstill or a readvance that occurred late during the Horcones glacier advance. These dates imply that the Penitentes advance may

    The aim of this work was to achieve a preliminary characterization of the profile of the phenolic fraction of virgin olive oils (VOOs) from Maipú (Mendoza, Argentina). Thus, 25 commercial VOO samples from Arauco, Arbequina, Picual, Frantoio, Changlot, Empeltre, Nevadillo, Manzanilla, and Coratina (both monovarietals and blends) were analyzed using LC-ESI-QTOF MS and LC-ESI-IT MS for identification and quantification purposes, respectively. A rapid LC method (15 min) accomplished quantitative information about a total of 40 phenolic compounds, including secoiridoid derivatives, which have not been evaluated before in samples coming from the subregion so-called Maipú (Mendoza province, Argentina). The results make evident that olive oils coming from Mendoza can be considered as important sources of phenolic bioactive compounds, exhibiting similar phenolic compound levels to those shown by oils from other typical world production regions. Moreover, some distinctive features of the Arauco variety (Argentinean autochthonous variety) were pointed out; indeed, a correlation between flavonoids content and botanical variety was established herewith.

    The feasibility of the application of chemometric techniques associated with multi-element analysis for the classification of grape seeds according to their provenance vineyard soil was investigated. Grape seed samples from different localities of Mendoza province (Argentina) were evaluated. Inductively coupled plasma mass spectrometry (ICP-MS) was used for the determination of twenty-nine elements (Ag, As, Ce, Co, Cs, Cu, Eu, Fe, Ga, Gd, La, Lu, Mn, Mo, Nb, Nd, Ni, Pr, Rb, Sm, Te, Ti, Tl, Tm, U, V, Y, Zn and Zr). Once the analytical data were collected, supervised pattern recognition techniques such as linear discriminant analysis (LDA), partial least square discriminant analysis (PLS-DA), k-nearest neighbors (k-NN), support vector machine (SVM) and Random Forest (RF) were applied to construct classification/discrimination rules. The results indicated that nonlinear methods, RF and SVM, perform best with up to 98% and 93% accuracy rate, respectively, and therefore are excellent tools for classification of grapes.

  6. Late Quaternary slip rates of two active thrust faults at the front of the Andean Precordillera, Mendoza, Argentina

    2010-12-01

    Several destructive earthquakes occurred in the last several hundred years along the active mountain front of the Andean Precordillera between 30°S and 33°S (Siame et al., 2002). However, slip rates of active reverse faults remain largely unknown and the seismic hazard related to these faults is still poorly constrained. Here we report slip rates for two active thrusts located north of Mendoza, the Penas and Cal thrusts, which offset Late Pleistocene to Holocene terraces and form well preserved fault scarps. At the Penas thrust three terraces (T1, T2 and T3) are displaced vertically by 0.9, 2 and 11 m, respectively. 10Be and 14C age constraints yield a vertical slip rate of ~0.9 mm/a for the Penas thrust fault. Combined with the dip angle of the fault of ~25°, this leads to a horizontal shortening rate of about 2 mm/a. At the Cal thrust the highest terrace, which has a maximum 10Be age of 12 ka, is displaced by ~7.5 m. This translates into a minimum horizontal shortening rate of about 1 mm/a. Comparison with short-term GPS data (Brooks et al., 2003) suggests that both the Penas and Cal thrusts accomodate a significant portion of the present-day E-W shortening rate in the eastern Andes. The vertical surface displacements derived from the smallest scarps is 0.9 m for both thrusts. Hence, given their length (Penas thrust: 40 km, Cal thrust: 31 km), these faults are capable of producing magnitude 7 earthquakes (Wells & Coppersmith, 1994), which is confirmed by a Ms = 7.0 earthquake on the Cal thrust that destroyed the city of Mendoza in 1861. Assuming characteristic earthquakes for both faults suggests average reccurence intervals of 1000 to 1500 years during the Holocene.

Facies of inner ramp, that were deposited in extremely shallow-water environments with intermittent subaerial exposures have been broken down into shallow subtidal, and intertidal-supratidal environments. Shallow subtidal facies are arranged into decimetre scale upward-shallowing cycles composed of marls, laminated or massive mudstones or bioclastic wackestones and intraclastic wackestone-packstones. Intertidal-supratidal centimetre-scale cycles consist of an upward-shallowing succession of restricted facies, overlaid by horizontal or crinkle microbial laminites, flat pebble conglomerates or breccias beds. The defined cycles show a shallowing upward trend in which the evidence of relative sea-level lowering is accepted. The interpretation of Fischer plots allowed the recognition of changes in accommodation space.

Le principal objectif de ce travail est d’analyser les effets hydrométéorologiques causés par ENSO dans la province de Mendoza, Argentine. Ensuite on étudiera les conditions météorologiques prédominantes (situations synoptiques les plus fréquentes et les phénomènes de méso-échelle associés pendant l’hiver, en plaine et dans la cordillère. On caractérise la zone étudiée hydrologiquement et climatologiquement. On utilise pour cela les données de débits mensuels des principales rivières de la région ainsi que les données climatiques, synoptiques et des images de satellite. Notre étude couvre les événements ENSO de ce siècle et plus particulièrement ceux de 1982-1983, 1986-1987, 1991-1993 et les premières manifestations de celui de 1997-1998. Les principaux résultats montrent, pour les années ENSO, une forte augmentation des débits des rivières à la fin du printemps et pendant l’été provoqué par l’excès de précipitation de l’hiver antérieur. Les plus forts débits ont été observés au cours de l'événement chaud de 1982-1983, considéré jusqu'à 1997 comme le plus fort de ce siècle. L’impact principal sur le régime hydrique est dû à l’anomalie positive de précipitations dans la partie de la cordillère qui a un régime hivernal. On en conclut que les plus fortes précipitations de la cordillère sont reliées à une augmentation de la fréquence des passages de zones de basse pression et d’incursions d’onde longue à des latitudes plus basses que la normale. Ceci provoque une anomalie négative dans le champ de pression de surface et des couches moyennes de l’atmosphère. El objetivo principal del trabajo es analizar los efectos hidrometeorológicos que ocasiona el evento cálido ENOS en la provincia de Mendoza, Argentina. Los objetivos secundarios son considerar las condiciones meteorol

    The International Road 7 crosses Argentina from East to West, linking Buenos Aires to the Chile border. Crossing the Andes Cordillera, it is exposed to numerous natural hazards, such as avalanches, rockfalls and debris flows. This study focuses on a catchment prone to debris flows above the International Road n° 7 between Potrerillos and Uspallata (Mendoza Province, Argentina) and is part of a regional study that assesses the hazard along the mountainous section of this road. The catchment measures 4.7 km2 and is constituted of three main torrents that unite a few meters above the International Road. Heavy rainfalls triggered debris flows in each of these torrents during the evening of 11 January 2005, reaching the road apparently at a very short interval of time. A car was hit by one of these debris flows and two people were injured. The study has been realized from Quickbird satellite imagery and field data principally. The conditions that triggered the debris flows in this catchment were established from meteorological data, as well as particle size and mineralogy of the material. Satellite imagery and a digital elevation model showed that the debris flows initiated mainly at the top of the catchment. Erosion of a highly altered granite produced abundant sandy material. The debris flows were classified as granular matrix with a collisional-frictional behavior. Various calculations of volumes, peak discharges and velocities (~ 7 m/s) were realized using different approaches. It appears that important volumes could be mobilized, especially in the longest torrent. A new event could imply more than 65'000 m3 of material. A detailed geomorphologic study shows the effect of mitigation works on the debris flows hazard. Indeed, the torrents were deviated towards a more adequate place for the construction of a road bridge. Three propagation scenarios show the limited efficiency of these works. The road bridge is under-dimensioned and deposits of the 2005 event have not

    Where the Neuquén Basin of Argentina abuts the Andes, hundreds of veins of solid hydrocarbon (bitumen) are visible at the surface. Many of these veins became mines, especially in the last century. By consensus, the bitumen has resulted from maturation of organic-rich shales, especially the Vaca Muerta Fm of Late Jurassic age, but also the Agrio Fm of Early Cretaceous age. To account for their maturation, recent authors have invoked regional subsidence, whereas early geologists invoked magmatic activity. During 12 field seasons (since 1998), we have tracked down the bitumen localities, mapped the veins and host rocks, sampled them, studied their compositions, and dated some of them. In the provinces of northern Neuquén and southernmost Mendoza, the bitumen veins are mostly sub-vertical dykes. They tend to be straight and continuous, crosscutting regional structures and strata of all ages, from Jurassic to Palaeocene. Most of the localities lie within 70 km of Tromen volcano, although four are along the Rio Colorado fault zone and another two are at the base of Auca Mahuida volcano. On both volcanic edifices, lavas are of late Pliocene to Pleistocene age. Although regionally many of the bitumen dykes tend to track the current direction of maximum horizontal tectonic stress (ENE), others do not. However, most of the dykes radiate outward from the volcanoes, especially Tromen. Thicknesses of dykes tend to be greatest close to Tromen and where the host rocks are the most resistant to fracturing. Many of the dykes occur in the exhumed hanging walls of deep thrusts, especially at the foot of Tromen. Here the bitumen is in places of high grade (impsonite), whereas further out it tends to be of medium grade (grahamite). A few bitumen dykes contain fragments of Vaca Muerta shale, so that we infer forceful expulsion of source rock. At Curacó Mine, some shale fragments contain bedding-parallel veins of fibrous calcite (beef) and these contain some bitumen, which is

    The Payenia Basaltic Province (PBP) is located 450 km east of the Chile-Peru trench in central west Argentina, behind the Andean arc front, constituting the back-arc. In order to evaluate the influence of the subducting slab as well as the magmatic source of this region, two volcanic fields located at comparable distance to the trench, having abundant basaltic products and similar eruptive timeframes were chosen. The Llancanelo (LLVF) and the Payún Matrú (PMVF) volcanic fields are part of the PBP and exhibit abundant basaltic activity during the Pleistocene. The geochemical data suggest that the LLVF has some arc signatures which have been described as weak as they are not as pronounced as in the Andean arc. The weak arc signature is not derived from slab dehydration as high Th enrichment relative to U cannot be explained by this process. We relate the Th enrichment as well as the lack of large residual garnet signatures, to slab sediments in the source. In the case of the PMVF, no arc signature has been inferred despite being only 30 km south of the LLVF. However the PMVF has a composition similar to that of the local intraplate end member, represented by the Rio Colorado volcanic field. The two volcanic fields, LLVF and PMVF, show indications of lower crustal assimilation as they trend towards the lower continental crust end member in Nb/U vs Ce/Pb and Nb/Yb vs Th/Yb diagrams. The geochemical differences between the LLVF and the PMVF as well as between several volcanic fields are illustrated using spatial distribution maps of geochemical ratios. Using this new approach, the decrease in arc signature can be traced in the back-arc and the higher enrichment in high field strength elements (HFSE) relative to large ion lithophile elements (LILE) in the PMVF compared to the LLVF is explicitly shown. These geospatial maps provide a graphical manner to illustrate the presence of two distinct types of volcanism (OIB-like and arc-like) occurring in the same Quaternary

    Full Text Available This paper estimates the volume of water used by the Mendoza food processing industry considering different water efficiency scenarios. The potential for using food processing industry effluents for irrigation is also assessed. The methodology relies upon information collected from interviews with qualified informants from different organizations and food-processing plants in Mendoza selected from a targeted sample. Scenarios were developed using local and international secondary information sources. The results show that food processing plants in Mendoza use 19.65 hm3 of water per year; efficient water management practices would make it possible to reduce water use by 64%, i.e., to 7.11 hm3. At present, 70% of the water is used by the fruit and vegetable processing industry, 16% by wineries, 8% by mineral water bottling plants, and the remaining 6% by olive oil, beer and soft drink plants. The volume of effluents from the food processing plants in Mendoza has been estimated at 16.27 hm3 per year. Despite the seasonal variations of these effluents, and the high sodium concentration and electrical conductivity of some of them, it is possible to use them for irrigation purposes. However, because of these variables and their environmental impact, land treatment is required.

    Snow avalanches commonly threaten people and infrastructure in mountainous areas worldwide. Winter precipitation events in the Central Andes are caused by the interaction of the atmospheric general circulation and their steep orography. Almost every winter season snow storms and winds cause the blockage of routes and lead to the snowpack conditions that generate avalanche events. The amount of winter snow accumulation is highly variable and is one of the most important factors for assessing the impacts of climate change not only on the water availability, but also to plan future mitigation measures to reduce the avalanche hazard. The authors have conducted studies on snow avalanches that regularly affect the international route linking Mendoza (Argentina) with Santiago de Chile (Chile) but none of them was done at the Aconcagua Provincial Park The park is nearby this route, about 13 km kilometers east from the international border, which in this sector of the Andes coincides with the continental divide. On the night of 17 August 2009, seven people were caught by an avalanche that hit the Aconcagua Park rangers refuge (32° 48' 40'' S, 69° 56' 33'' W; 2950 masl).This paper describes the meteorological and snow precipitation conditions originating the event. On August 14 th. the synoptic surface and upper-air conditions from NCEP reanalysis were those associated with a severe Zonda wind occurrence in the region, that is: a 500 hPa level trough, a deep low-pressure surface system located over the Pacific Ocean close to the Chilean coast, approximately over 48 ° S and 80° W, and a jet stream at middle upper-air levels. The avalanche event occurred during a new and very heavy snowfall a while more than two days later of these extreme episodes. The topographical characteristics of the avalanche path, the snow storm intensity and the snow accumulation on the avalanche starting zone allowed the authors to simulate the avalanche flow.

    This paper describes different ways of reducing urban air temperature and their results in two cities: Campinas, Brazil—a warm temperate climate with a dry winter and hot summer (Cwa), and Mendoza, Argentina—a desert climate with cold steppe (BWk). A high-resolution microclimate modeling system—ENVI-met 3.1—was used to evaluate the thermal performance of an urban canyon in each city. A total of 18 scenarios were simulated including changes in the surface albedo, vegetation percentage, and the H/W aspect ratio of the urban canyons. These results revealed the same trend in behavior for each of the combinations of strategies evaluated in both cities. Nevertheless, these strategies produce a greater temperature reduction in the warm temperate climate (Cwa). Increasing the vegetation percentage reduces air temperatures and mean radiant temperatures in all scenarios. In addition, there is a greater decrease of urban temperature with the vegetation increase when the H/W aspect ratio is lower. Also, applying low albedo on vertical surfaces and high albedo on horizontal surfaces is successful in reducing air temperatures without raising the mean radiant temperature. The best combination of strategies—60 % of vegetation, low albedos on walls and high albedos on pavements and roofs, and 1.5 H/W—could reduce air temperatures up to 6.4 °C in Campinas and 3.5 °C in Mendoza.

La mayoría de la bibliografía sobre el tema analiza los procesos políticos o económicos en forma separada y por ello hemos considerado que ir engarzando ambas perspectivas, enriqueciéndolas con nuevos aportes de fuentes, constituye una contribución novedosa para la historia de la provincia en esos años. Es nuestra intención mostrar cómo los cambios en la estructura económica y social que se produjeron en el país y en Mendoza alrededor de 1880 van a introducir en el panorama histórico nuevos actores, nuevos conflictos y nuevos mecanismos de integración y de control. Para analizar el proceso de cambio de las relaciones políticas, económicas y sociales, no nos detendremos solamente a analizar quiénes eran los actores que participaban en el proceso de adopción de decisiones para esos cambios, sino que también intentaremos responder a la pregunta “poder para qué”, es decir a desentrañar cuáles eran las relaciones políticas, sociales y económicas que desde el estado se estaban potenciando, destruyendo o manteniendo.

    Here we describe the unusual genesis of steptoes in Las Bombas volcano- Llancanelo Volcanic Field (LVF) (Pliocene - Quaternary), Mendoza, Argentina. Typically, a steptoe forms when a lava flow envelops a hill, creating a well-defined stratigraphic relationship between the older hill and the younger lava flow. In the Llancanelo Volcanic Field, we find steptoes formed with an apparent normal stratigraphic relationship but an inverse age-relationship. Eroded remnants of scoria cones occur in ;circular depressions; in the lava field. To express the inverse age-relationship between flow fields and depression-filled cones here we define this landforms as inverse steptoes. Magnetometric analysis supports this inverse age relationship, indicating reverse dipolar magnetic anomalies in the lava field and normal dipolar magnetization in the scoria cones (e.g. La Bombas). Negative Bouguer anomalies calculated for Las Bombas further support the interpretation that the scoria cones formed by secondary fracturing on already solidified basaltic lava flows. Advanced erosion and mass movements in the inner edge of the depressions created a perfectly excavated circular depression enhancing the ;crater-like; architecture of the preserved landforms. Given the unusual genesis of the steptoes in LVF, we prefer the term inverse steptoe for these landforms. The term steptoe is a geomorphological name that has genetic implications, indicating an older hill and a younger lava flow. Here the relationship is reversed.

    Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In temperate-cold arid regions with a generous solar resource, such as those of western Argentina, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. The solar potential of low-density residential urban areas in the city of Mendoza's Metropolitan Area (MMA), has been studied earlier in this research. Several indicators of the solar potential were elaborated. They provide necessary information when planning and designing new urban structures or refurbishing existing ones. However, a more direct indicator, relating the available solar radiation during a heating season to the space volume to be heated, the Volumetric Insolation Factor (VIF), seems to be of most practical use as far as contributing a helpful evaluation indicator, to the above mentioned design processes. The present study follows the methodological steps used in the former research, evaluating comparatively the results of a Graphic-Computational Model and a Multiple Linear Regression Statistical Model. As in the earlier study, the good fit of both models' results clearly point at the reliability of the statistical procedure and its valuable contribution of a simplified calculation tool as its by-product.

    Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In tempered-cold arid regions with a generous solar resource, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. This study assessed the solar potential of low-density urban environments in the city of Mendoza, Argentina. The results of the study will be used to develop technical guidelines for urban and energy planning agencies and professionals involved in the production of habitat. The study included the following successive steps: (i) selection of a representative sample of analysis units (city blocks); (ii) selection of a series of urban and building variables; (iii) definition of indicators accounting for solar masking, building's potential use of the solar radiation on the whole urban area, and availability of adequate collecting areas to satisfy high percentages of the energy demand in low-density urban environments; and (iv) insolation of potential collectors simulated by a graphic-computational model developed in the R and D unit. Only the results for solar space heating are presented in this paper. The results, direct and statistical, indicate that it is technically feasible to meet the target solar fractions. At the same time, by means of the solar recycling of existing building stocks, it is possible to considerably reduce the environmental impacts due to the extraction of materials from, and the disposal of solid wastes into, the ecosystem.

En este trabajo se analizan, de manera comparativa, cuatro ensayos con diferentes sistemas de aplicación de enmiendas orgánicas (prácticas agrícolas, tipo de enmienda, dosis, frecuencia y forma de aplicación y combinación con fertilizantes químicos en oasis de regadío de Mendoza (Argentina, con la finalidad de establecer las prácticas de manejo más adecuadas para restaurar las diferentes fracciones de MO del suelo (ácidos húmicos y fúlvicos y sustancias no húmicas. El contenido de MO aumentó en el 40% de los casos analizados (n=92 y no sufrió modificaciones en el resto, mientras que los ácidos fúlvicos también aumentaron en el 40% de los casos, pero disminuyeron en el 30%. Contrariamente, los ácidos húmicos sufrieron más disminuciones que aumentos (39% vs. 26% de los casos. Estas diferencias se explican por las prácticas de manejo agrícola y las técnicas de aplicación de las enmiendas, concluyendo que: a todas las prácticas de aplicación de enmiendas aumentan en el corto plazo la MO; b la fracción humificada aumenta en el corto plazo, con la aplicación superficial sin laboreo; y c el agua de riego con alto contenido de desechos orgánicos disminuye el efecto positivo de las enmiendas sobre la MO. Por tales motivos, las prácticas de manejo recomendadas para lograr la restauración de la MO del suelo en los oasis de regadío de Mendoza son: aumentar la dosis y la frecuencia en la aplicación de enmiendas, y reducir el laboreo y el uso de aguas de reuso.

Durante las últimas décadas, el Valle de Uco basó su patrón de desarrollo agrícola en un modelo intensivo y empresarial de sus tres principales cultivos: los viñedos, los frutales y las hortalizas. En la actualidad, atraviesa un proceso de profunda reconversión productiva, orientada mayoritariamente hacia el mercado externo, que entre otras consecuencias pasó a modificar el funcionamiento del mercado de trabajo local. En este artículo, se contemplan las diferentes situaciones que llevan al ingreso laboral de los jóvenes en este contexto, según el momento etáreo que atraviesen. Se analiza la relación que este proceso guarda con el tamaño y la estructura de las familias y la situación socio-económica del hogar al que pertenecen. También, se examina el vínculo entre las características de los hogares y la forma de inserción de los jóvenes en el mercado de trabajo, de acuerdo al tipo de ocupación en la que se desempeñan y al destino que le dan a sus ingresos. A partir de la realización de entrevistas en profundidad a trabajadores jóvenes y a informantes clave se pudo dar cuenta de las preferencias de los jóvenes con respecto a distintos tipos de trabajos, con particular énfasis en ciertos trabajos agrícolas y, también en relación a su futuro laboral.This article deals with the different ways that young workers in the Uco Valley, at the province of Mendoza, enter to the agrarian local labour market.

    Full Text Available During the last decade of the XIX century and the first two decades of the XX, the argentine province of Mendoza underwent substantial territorial, economical and society changes due to the advance of the capitalism, that formed one of the first regional economy of the country: the viticulture industry. The capitalist development produced an unknown economic expansion in which all the indicators increased in number: extent of the agrarian cultivation, wine vault installment, raise of the capacity of wine elaboration, technological improvement. Pertaining to society land subdivision, enterprise class arising and enlargement of the middle class. However, the majority of the popular sectors, enlarged by the overseas immigration, suffered life conditions characterized by low incomes which were maintained in face values during the studied period, and home and health problems that derived in the propagation of serious contagious disease and high children death rate. This article shows the contrast between a powerful productive forces development and the miserable conditions of population life.

A tal fin se seleccionaron tres casos de estudio, donde se evaluó el comportamiento de distintas estructuras presentes en las plazas. Para ello se desarrollaron mediciones de temperatura del aire mediante sensores fijos, durante un periodo de 40 días en la estación verano de 2012, los sensores fueron ubicados en las diferentes estructuras (bosque, prado y centro de la plaza y en su entorno urbano, siguiendo un eje en sentido norte-sur. Además se determinó el valor del factor de visión de cielo (SVF y la digitalización hemisférica de la trayectoria solar para todos los puntos evaluados. Los resultados ponen de manifiesto la necesidad de reflexionar y revisar las estructuras de plazas existentes, en cuanto a sus esquemas de diseño, dado que el esquema tradicional que plantea una distribución de espacios en forma simétrica, parece no ser el que combina en forma más eficiente las distintas variables involucradas en el comportamiento térmico de la plaza: materialidad, distribución de la vegetación y exposición solar. Además se observa que a menor densidad edilicia del entorno urbano en el cual se inserta la plaza, sus condiciones térmicas y su eficiencia ambiental pueden mejorarse, casi con independencia de otros factores, mediante un diseño apropiado del espacio.

This study was conducted during two consecutive vintages to assess its influence on the general composition, sensory attributes and preference of Vitis vinifera L. cv Malbec wines. Batches of 120 kg of grapes harvested from vines with different degrees of (visual symptoms of the disease were separately vinified. Grapes were grouped in three treatments: T1, grapes from vines with no symptoms; T2, grapes from vines with 10%–50% symptoms; and T3, grapes from vines with 50%–100% symptoms. Basic analyses of the grapes prior to crushing, and basic wine analysis were undertaken, together with spectrophotometric analyses of the wines after three months of bottle aging. The kinetics of alcoholic fermentation (AF was followed daily and additionally the wines were assessed by a sensory panel. T3 grapes were characterized by comparatively lower initial sugar contents and higher titratable acidity. The AF kinetics were unaffected in the wines arising from the diseased grapes. There was no clear-cut effect of the disease on the wines’ pH, volatile acidity, and total acidity; however, the later spectrophotometric analyses showed that the total phenolic index was the highest in T2 wines for both vintages. In 2005, the color index (CI was higher in T3 and showed the lowest value in 2006. The sensory properties of the wines were different in the two vintages. In 2005, T2 and T3 wines were perceived as having higher color intensity, violet hue and spicy notes, T2 being the most preferred wine. In 2006, T1 and T2 showed a much better sensory

    A tectonically affected Middle Ordovician succession crops out at the Los Guanacos quarry in the sierra de Las Higueras, in the Precordillera of Mendoza, western Argentina. This is represented by the San Juan Formation which is transitionally covered by a mixed carbonate-shaly unit of dark colours, 1.5 metres thick (transfacies) which can be interpreted as the base of the Los Azules Formation. A 5-cm thick intra-bioclastic pack/grainstone bed interbedded in the lower part of this unit has been interpreted as a tempestite. It is characterized both by a millimetre-thick erosional boundary, just above the dark mudstone layer and strong mechanical distribution of bioclasts and intraclasts, suggesting sedimentary structures associated with a storm event of high energy possibly occurring in the middle part of the platform. Towards the bottom, a hummocky structure thin interval, under the dark mudstone, is interpreted as the record of another tempestite event. The mudstone represents the post-storm event reflecting the low energy of the marine water environment. The lenticular layer contains predominantly lingulid shells, trilobites and graptolites, all highly fragmented, which suggests they have been reworked and subsequently mixed and quickly redeposited during a storm event that caused the mortality of these faunas. The trilobites Mendolaspis salagastensis and indeterminate species of Matagnostidae, Illaenidae, Leiostegiidae, Encrinuridae, Telephinidae and Trinucleidae have been recorded for the first time at this locality. The conodont fauna allows the identification of the Yangtzeplacognathus crassus Zone, which indicates the lower Darriwilian (Middle Ordovician). Graptolites assignable to evisograptus cf. Levisograptus austrodentatus and Levisograptus sp. are described for the first time in the studied area and biostratigraphic implications validate the early Darriwilian age for the bearing levels. Finally, based on the studied records, correlation with different

    Full Text Available This article evaluates the thermal and energy performance of two wineries in the province of Mendoza, Argentina (32° 40’ S, 68° 51’ W, 750m above sea level. The grape harvesting period (February–March was selected for analysis because cooling demand at that time is higher: tons of hot raw material (at approximately 26-30°C enter the wineries to be processed at 8°C, while outdoor temperatures are around 38°C. The selected wineries have similar-sized buildings and the same quantity and quality of production, but different management and envelope materiality. Winery P was built with walls of traditional bricks, single pane windows and a metal roof with thermal insulation; while winery H´s walls were partially built of reinforced concrete panels with thermal insulation, insulated metal roofs and double pane windows. Air, envelope surface, relative humidity and solar radiation temperatures were measured in situ and studied in relation to the energy consumption records of each winery. Then, with the data obtained, a model was generated with Energy Plus software, which was used to simulate envelope improvement alternatives. As a result, both wineries showed improved performance. The temperatures measured in winery P reached an average of 18.89 °C without the use of auxiliary energy. In the case of winery H, temperatures were optimized, thereby achieving an average of 21.77 °C, once again without the use of auxiliary energy. Moreover, it is possible to integrate night ventilation strategies using outdoor temperatures that decrease 9.78 °C in the period analyzed. The thermal and energy refurbishment proposal, which integrates building and envelope improvements, results in minimum indoor temperatures of 15.65 °C without the use of auxiliary energy--optimal for wine production.

    The Pampas Onduladas flow in southern Mendoza, Argentina, is one of the four longest Quaternary basaltic flows on Earth. Such flows (> 100 km) are relatively rare on Earth as they require special conditions in order to travel long distances and there are no recent analogues. Favourable conditions include: a gentle topographic slope, an insulation process to preserve the melt at high temperature, and a large volume of lava with relatively low viscosity. This study investigates the rheological and geochemical characteristics of the ~ 170 km long Pampas Onduladas flow, assessing conditions that facilitated its exceptional length. The study also reports the first geochronological results for the Pampas Onduladas flow. 40Ar/39Ar step-heating analyses of groundmass reveal an eruption age of 373 ± 10 ka (2σ), making the Pampas Onduladas flow the oldest Quaternary long flow. The methods used to assess the rheological properties include the application of several GIS tools to a digital elevation model (DEM) to determine the length, width, thickness, volume and topographic slope of the flow as well as algorithms to determine its density, viscosity and temperature. The slope of the Pampas Onduladas flow determined from the initial part of the flow on the eastern side of La Carbonilla Fracture to its end point in the province of La Pampa is 0.84% (0.29°), the steepest substrate amongst long Quaternary flows. The rheological properties, such as density viscosity and temperature from the Pampas Onduladas flow are similar to values reported for other long Quaternary flows. However, the minimum volume calculated is relatively low for its length compared with other long Quaternary flows. Therefore, the extension of the Pampas Onduladas flow was probably controlled by a steep slope, combined with an insulating mechanism, which helped in providing optimal conditions for a travel length of almost 170 km.

    The Payún Matrú Volcanic Field constitutes part of the continental back-arc in Argentina. This volcanic field has been the focus of several regional investigations; however, geochemical analysis of recent volcanoes (<8 ka) at the scale of an individual volcano has not been conducted. We present a morphological description for the Santa Maria Volcano in addition to results from major and trace element analysis and 238U-230Th-226Ra disequilibria. The trace element evidence suggests that the Santa Maria magmatic source has a composition similar to that of the local intraplate end member (resembling an ocean island basalt-like source), with a slight contribution from subduction-related material. The U-series analyses suggest a high 226Ra excess over 230Th for this volcano, which is not derived from a shallow process such as hydrothermal alteration or upper crustal contamination. Furthermore, intermediate-depth processes such as fractional crystallisation have been inferred for the Santa Maria Volcano, but they are not capable of producing the 226Ra excess measured. The 226Ra excess is explained by deep processes like partial melting of mantle lithologies with some influence from subducted Chilean trench sediments. Due to the short half-life of 226Ra (1600 years), we infer that fast magma ascent rates are required to preserve the high 226Ra excess.

    Soil temperatures of the active Volcanic Complex Peteroa situated in the Cordillera Principal between Chile and Argentina at 35°15‧ S and 70°35‧ W (approximately) were monitored in the area, and local geomorphology (periglacial geomorphology, presence of permafrost, and cryoforms) was studied. The present contribution also resulted in a comparison of two consecutive analyses of the volcano peak carried out with special thermocameras (AGEMA TVH 550, FUR P660) in order to study the thermal range of different hot and cold sites selected in 2009. The thermocameras were used ascending by foot and also during flights with a Cessna 180. A night expedition to the volcanic avalanche caldera, at up to 3900 m asl (approximately), completed the monitoring activity of 2010. Hot zones were associated to present volcanism and cold zones to the presence of glacier ice and shadowy slopes with possible presence of permafrost. Identifying and mapping uncovered and covered ice was possible with the help of monitoring and geomorphological interpretation related to the upper englacement, which is severely affected by volcanism. Glaciers are retreating toward the north or approaching the rims of the volcanic avalanche caldera leaving islands of ice associated with superficial permafrost. The cryogenic area with slope permafrost was identified through active protalus and sedimentary cryogenic slopes. Craters have undergone considerable thermal changes in comparison to the year 2009; and new, much more vigorous fumaroles have appeared in hot areas detected in 2009 following a tendency toward the west. New subaquatic heat columns that appeared in crater 3, crater walls, and glaciated areas vanished, supplying cold water and thus contributing to the formation of a new lake in crater 4. A possible post-seismic shift of the volcanic activity may provide geodynamical evidence of the changes registered in other areas after the earthquake of 27 February 2010.

    In the northern Neuquén Basin of Argentina (especially in Mendoza Province), there is strong geological evidence for fluid overpressure in the past. The evidence takes the form of bitumen veins and bedding-parallel veins of fibrous calcite ('beef'). Such veins are widespread in the fold-and-thrust belt of the Malargűe area, where bitumen mining has been active for a century or so. So as to collect information on the development of fluid overpressure in this part of the Neuquén Basin, several old mines were visited and studied in the Malargűe area. Here the bitumen veins have intruded mainly the Late Jurassic to Early Cretaceous Mendoza Group, but also the Late Cretaceous Neuquén Group. The veins have the forms of bedding-parallel sills or dykes and they are especially thick within anticlines, forming saddle-reefs in several places. Beef veins are also numerous in the Malargűe area. They contain bitumen and therefore seem to have formed at the same time as the bitumen veins. Near many outcrops of bitumen and beef, we have found fine-grained volcanic intrusive bodies. The best examples are from the La Valenciana syncline. According to 39Ar-40Ar dating, these bodies are mainly of Mid-Miocene age. More generally, volcanism, deformation and maturation of source rocks seem to have reached a climax in Miocene times, when the subducting Pacific slab became relatively flat.

    The La Peña alkaline igneous complex (LPC) is located in the Precordillera (32°41‧34″ S - 68°59‧48″ W) of Mendoza province, Argentina, above the southern boundary of the present-day flat-slab segment. It is a 19 km2 and 5 km diameter subcircular massif emplaced during the Miocene (19 Ma) in the Silurian-Devonian Villavicencio Fm. The LPC is composed of several plutonic and subvolcanic intrusions represented by: a cumulate of clinopyroxenite intruded by mafic dikes and pegmatitic gabbroic dikes, isolated bodies of malignite, a central intrusive syenite that develops a wide magmatic breccia in the contact with clinopyroxenite, syenitic and trachytic porphyries, a system of radial and ring dikes of different compositions (trachyte, syenite, phonolite, alkaline lamprophyre, tephrite), and late mafic breccias. The main minerals that form the LPC, ordered according to their abundance, are: pyroxene (diopside, hedenbergite), calcium amphibole (pargasite, ferro-pargasite, potassic-ferro-pargasite, potassic-hastingsite, magnesio-hastingsite, hastingsite, potassic-ferro-ferri-sadanagaite), trioctahedral micas (annite-phlogopite series), plagioclase (bytownite to oligoclase), K-feldspar (sanidine and orthoclase), nepheline, sodalite, apatite group minerals (fluorapatite, hydroxylapatite), andradite, titanite, magnetite, spinel, ilmenite, and several Cu-Fe sulfides. Late hydrothermal minerals are represented by zeolites (scolecite, thomsonite-Ca), epidote, calcite and chlorite. The trace element patterns, coupled with published data on Sr-Nd-Pb isotopes, suggest that the primary magma of the LPC was generated in an initially depleted but later enriched lithospheric mantle formed mainly by a metasomatized spinel lherzolite, and that this magmatism has a subduction-related signature. The trace elements pattern of these alkaline rocks is similar to other Miocene calc-alkaline occurrences from the magmatic arc of the Southern Central Andes. Mineral and whole

    The evaluation of historical information can give valuable insight into past glacier dynamics, especially before the onset of modern measurements. Early photographs and maps depict changes for selected glaciers in southern South America. Within this study, written documents and pictorial historical records (drawings, sketches, engravings, photographs, chronicles, topographic maps) are analysed critically, with a particular focus on two regions: Lago Viedma (El Chaltén, southern Patagonia, 49.5°S, 73.0°W) and the Río Mendoza basin (Mendoza, central Andes, 33.1°S, 69.9°W). For the Lago Viedma area, early historical data for the end of the 19th century stem from the expedition of the Chilean-Argentinean border commission. In addition, the expedition by the German Scientific Society, conducted between 1910 and 1916, and the later photographs by Alberto M. de Agostini give an excellent depiction of the glaciers. Glaciar Viedma is a calving glacier which shows distinct retreat from 1896 until the present (though with a stationary or possibly advancing glacier front between 1930/31 and 1951/52), similar to the neighbouring glaciers. On the contrary, nearby Glaciar Perito Moreno shows an exceptional behaviour: the glacier front has been advancing during the first half of the 20th century, staying in an advanced position until the present. At the beginning of the 20th century, Robert Helbling explored the Argentinean-Chilean Andes together with his friend Friedrich Reichert. In the summer of 1909/10, they started a detailed survey of the highly glacierized Juncal-Tupungato mountains (Río Mendoza basin), leading to the first accurate topographic map of the area published in 1914. Its outstanding quality allows a comparison with contemporary satellite imagery. The area received attention in 1934, when the sudden drainage of a glacier-dammed lake in the upper Río del Plomo valley caused fatalities and considerable damage to constructions and the Transandine Railway.

    This monocenter, descriptive, prospective, non-interventional study evaluated the long-term immune responses following routine vaccination with one or 2 doses of a licensed inactivated hepatitis A (HA) vaccine (Avaxim® 80U Pediatric) at age 11-23 months in a cohort of children from Mendoza, Argentina. Antibodies to hepatitis A virus (anti-HAV) were quantified annually up to Y5, and at Y7. Children whose titer decreased to below the seroprotection threshold (defined as an anti-HAV antibody concentration of ≥ 10 mIU/mL in a microparticle enzyme immunoassay up to Y5, or ≥ 3 mIU/mL in an electrochemiluminescence immunoassay at Y7) received a routine booster dose of the same HA vaccine. This report summarizes the data at 7 year after the first vaccination. Of 546 participants initially included, 264 participants remained at Y7 and provided blood samples. Of these, 204 having received one HA primary dose as a toddler were still seroprotected at Y7; titers for a further 7 also having received one HA dose as a toddler fell to below the seroprotection threshold and they therefore received a booster; all 53 having received 2 HA doses as a toddler and still present at Y7 remained seroprotected at Y7. One or 2 primary doses of this HA vaccine in toddlers result in very good persistence of anti-HAV up to 7 year post-first vaccination.

    The Late Jurassic - Early Cretaceous marine sediments of the Andean region show an excellent record of different calcareous microfossils, among which calcareous dinoflagellate cysts stand out. Detailed micropaleontological studies of Vaca Muerta Formation (Early Tithonian - Early Valanginian) in the southern Mendoza Neuquén Basin from three sections are conducted with the aim of establishing a major presence of microfossil representatives from different microfossil groups. The analysis of several thin sections from the outcrops reveals a relatively rich micropaleontological assemblage of calcareous dinoflagellate cysts, as well as levels with poor preserved calpionellids and benthic foraminifera. Particularly, calcareous dinoflagellate cyst includes 24 known species (two of them with two subspecies). Some species with biostratigraphic value of the Tethyan region have been identified also in the Andean region: 1) Committosphaera pulla (Borza) and Parastomiosphaera malmica (Borza) are species known only from Lower Tithonian; 2) Colomisphaera tenuis (Nagy) appears in the latest Early Tithonian; 3) Colomisphaera fortis Řehánek and Stomiosphaerina proxima Řehánek are important markers for the latest Late Tithonian - middle Late Berriasian interval; 4) Stomiosphaera wanneri Borza appears in the middle Late Berriasian; 5) Colomisphaera conferta Řehánek and Colomisphaera vogleri (Borza) appear in the Late Berriasian and marked the Berriasian-Valanginian boundary interval; 6) Carpistomiosphaera valanginiana Borza is a marker for the Lower/Upper Valanginian. More detailed studies of these groups will allow their correlation with Tethyan biozones, and contribute to improve biostratigraphic schemes in the Neuquén Basin.

  3. Slip rates of active thrusts at the front of the Precordillera revealed by exposure dating and fault scarp profiles, Mendoza, Argentina

    Although large historical earthquakes occurred in the Andean back-arc region between 28° and 34°S, the slip rates of active reverse faults remain unknown; hence the seismic hazard related to these faults is poorly constrained. Here we report long-term slip rates for two faults - the Peñas and the Cal thrust - which define the front of the Andean Precordillera north of Mendoza. Both thrusts displace several Late Pleistocene to Holocene river terraces and form well-preserved fault scarps. At the Peñas thrust three terraces (T1, T2, and T3) are displaced vertically by ~0.9, ~1.9 and ~11 m, respectively. 10Be exposure dating constrains the age of T2 and T3 as 2.9 ± 0.8 ka and 11.1 ± 1.7 ka, which yields an uplift rate of 0.9 ± 0.1 mm/a. The horizontal shortening rate of the Peñas thrust - calculated by using the age of T3 and the dip angle of 25° - is 1.9 ± 0.2 mm/a. At the Cal thrust a fault scarp has displaced a terrace with a maximum age of 12 ka by 7 m. As the Cal thrust dips ~25°, this yields a shortening rate of ≥ 1.3 mm/a. Our results demonstrate that the two thrusts accomodate about half of the present-day shortening rate in the back-arc region of the Andes, which is constrained as 4.5 ± 1.7 mm/a (Brooks et al., 2003). Using the compilation of Well & Coppersmith (1994), the 50-km-long Peñas and the 31-km-long Cal thrusts are capable of producing earthquakes with a magnitude of Mw 6.7 to 7.0. This is supported by a magnitude Ms ~ 7.0 earthquake on the Cal fault, which devastated Mendoza in 1861 and killed two thirds of its population. Earthquakes of this magnitude have presumably generated the smallest fault scarps (~0.9 m vertical offset) present at both thrusts. The higher scarps are interpreted to record multiple offsets generated during several Holocene earthquakes.

    The type A of neurotoxin produced by Clostridium botulinum is the prevalent serotype in strains of Mendoza. The soil is the main reservoir for C.botulinum and is possibly one of the infection sources in infant botulism. In this study, we characterized and compared autochthonous C. botulinum strains and their neurotoxins. Bacterial samples were obtained from the soil and from fecal samples collected from children with infant botulism. We first observed differences in the appearance of the colonies between strains from each source and with the A Hall control strain. In addition, purified neurotoxins of both strains were found to be enriched in a band of 300 kDa, whereas the A-Hall strain was mainly made up of a band of ∼600 kDa. This finding is in line with the lack of hemagglutinating activity of the neurotoxins under study. Moreover, the proteolytic activity of C. botulinum neurotoxins was evaluated against SNARE (soluble N-ethylmaleimide-sensitive factor-attachment protein receptor) proteins from rat brain. It was observed that both, SNAP 25 (synaptosomal-associated protein 25) and VAMP 2 (vesicle-associated membrane protein) were cleaved by the neurotoxins isolated from the soil strains, whereas the neurotoxins from infant botulism strains only induced a partial cleavage of VAMP 2. On the other hand, the neurotoxin from the A-Hall strain was able to cleave both proteins, though at a lesser extent. Our data indicate that the C.botulinum strain isolated from the soil, and its BoNT, exhibit different properties compared to the strain obtained from infant botulism patients, and from the A-Hall archetype.

  6. Subduction controls on Miocene back-arc lavas from Sierra de Huantraico and La Matancilla and new 40Ar/39Ar dating from the Mendoza Region, Argentina

    Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquén has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic areas of the region, the neighboring Huantraico and La Matancilla plateaus, including new 40Ar/39Ar age results of major and trace elements as well as Nd, Sr and Pb isotopic data. Four million years of eruptions from 24.4 ± 0.3 Ma (2σ) of alkali olivine basalts with OIB-type incompatible trace element enrichments at La Matancilla (~ 36.50°S) provide evidence for the presence of back-arc mantle devoid of subduction-related components. In contrast, the lower Huantraico lavas (~ 37.30°S) require an atypical back-arc mantle, almost devoid of arc-like components (e.g. low La/Ta = 15-18 and Ba/La = 12-18), but with a more depleted isotopic signature (e.g. 87Sr/86Sr, 0.7033-0.7037) than observed elsewhere in the Andean back-arc. The Lower to Upper Series development in the Huantraico sequence represents a gradual change from basaltic to trachyandesitic back-arc lavas with a weak but temporally increasing arc geochemical signature (e.g. La/Ta = 15-21; Ba/La = 12-45), which is accompanied by Sr, Nd and Pb isotopic compositions approaching present day values of the Andes arc. The compositional change is accompanied by a gradually decreasing role for garnet in the mantle source, a decreasing degree of melting, but also simultaneously increasing influence from subducted fluids, probably as the slab geometry changes through time. The volcanism at Huantraico ceased when a flat slab was established around 15 Ma.

    Detailed sedimentological, sequence stratigraphical and cyclostratigraphical analyses have been made from four lower Tithonian-lower Valanginian sections of the Vaca Muerta Formation, exposed in the southern Mendoza area of the Neuquén Basin, Argentina. The Vaca Muerta Formation is characterized by decimetre-scale rhythmic alternations of marls, shales and limestones, and consists of five facies associations, which reflect different paleoenvironmental conditions: basin to restricted outer ramp, outer ramp, and middle ramp. Vertical organization within the Vaca Muerta Formation shows a well-ordered hierarchy of cycles, where elementary cycles, bundles and superbundles with frequencies within the Milankovitch band have been recognized. According to biostratigraphic data, elementary cycles have a periodicity of ~ 20 ky, which correlates with the precession cycle of Earth's axis. Spectral analysis based on series of cycle thickness allows us to identify frequencies of about 400 ky and 90-120 ky, which we interpret as the modulation of the precessional cycle by the Earth's orbital eccentricity. Cycles are probably driven by variations in carbonate exportation, as fluctuations in shallow-water carbonate production involve modifications in carbonate basinward exportation. Cyclostratigraphic data allowed us to build a floating orbital scale for the Tithonian-lower Valanginian interval in the Neuquén Basin. Correlation between studied sections allowed us to recognize a discontinuity between the Substeueroceras koeneni and Argentiniceras noduliferum ammonite zones in the Malargüe Anticline area. Orbital calibration of these sections is consistent with Riccardi's biostratigraphic scheme, wich place the Jurassic-Cretaceous boundary within the Substeueroceras koeneni ammonite Zone. On the other hand, the base of the Vaca Muerta Formation (Virgatosphinctes mendozanus ammonite Zone) would be probably placed in the base of the middle Tithonian rather than the lower Tithonian

    An interval counting technique and standard cumulative statistics, in concert with residual and differential slope analysis, are employed on multiple parallel scanlines to test the applicability of fractal fault spacing at the El Teniente Mine, Central Chile. A negative exponential distribution best describes fault spatial distribution at the mine, while the interval counting method gives deceptively good fits to a fractal distribution. The results are consistent for the majority of the scanlines over thousands of square meters. These data provide an important counterexample to previously studied fractal spacing distributions and suggest that faulting is not a uniquely self-similar process and/or that faulting is not a consistently self-similar process through time. The "Fold Style Inversion" (FSI) method is developed to place quantitative bounds on balanced cross-sections used in the analysis of blind thrust faults. The method employs a discretized dip isogon construction, in combination with Monte Carlo simulations of seismic reflection depth-conversion errors, to assess a data sets' goodness of fit to bulk hangingwall similar or parallel fold geometry. This enables an objective choice to be made between the Arbitrarily Inclined Simple Shear (AISS) and Constant Bed Length (CBL) fault inversion routines which are specific to similar and parallel fold geometry, respectively. The method performs successfully for a variety of synthetic examples including a synthetic seismic line. The FSI method is applied to seismic reflection lines crossing the Barrancas and Lunlunta-Carrizal anticlines, active fault-bend folds in the Andean foreland of Mendoza Province, Argentina, and the proposed site of the 1985 Mw 5.9 Mendoza earthquake. For the Barrancas anticline, FSI analysis establishes a preference for similar fold style whereas no preference can be established for the Lunlunta-Carrizal anticline. With FSI-constrained cross-sections, it is shown that the earthquake most

    In southern South America the acquisition of high-quality Holocene paleoclimate data is a priority due to the paucity of complete, continuous and well dated records. Here we report preliminary results from a combined sedimentological and palynological study of an alluvial fan sequence and the laterally connected sedimentary deposits of the Vega de la Cueva profile at Agua Buena east of the Andes in central Argentina. The main geomorphological units of the area were identified and mapped based on satellite image analysis and multiple field surveys. The sedimentological and pollen results allowed us to reconstruct the development of some environments. The Agua Buena record corresponds to the distal facies of the Arroyo Bayo alluvial fan starting the aggradation process prior to ca. 4100 cal yr BP. The organic-rich levels found were formed during the development of wetlands (vegas) dominated by Cyperaceae, Juncaceae and Poaceae. These highly productive environments with almost permanent water saturation were important between 4100 and 2800 cal yr BP, indicating more stable conditions. After 2800 cal yr BP, the organic content was comparatively lower with increasing sedimentation rates that are indicative of higher fluvial discharges. This information is fundamental to interpret both the pollen and charcoal records of the area and to evaluate their representativeness and potential to reconstruct past local and/or regional vegetation.

    Full Text Available El artículo traza un panorama de los cambios verificados en la vitivinicultura de la gran región productora de vinos de la Argentina durante los últimos 35 años, con especial mención a las innovaciones institucionales, impresariales, técnicas y laborales registradas. La mención de algunos antecedentes sobre un siglo de trayectoria vitivinícola permiten apreciar con mayor claridad las transformaciones recientes de la agroindustria y el papel de los diferentes actores sociales involucrados. Particularmente destacados son los cambios operados por el Estado, que actuó como promotor, regulador y empresario, desregulador y, nuevamente, promotor, pero siempre articulado con los sectores empresarios. El acelerado proceso de cambios desde la década de 1990 supuso una reorientación de la actividad, otrora concentrada en el mercado interno, para posicionar a la región en lugares de creciente relevancia en el mercado internacional de vinos finos. El análisis a escala regional se complementa, finalmente, con los cambios que se producen a escala de empresas y las estrategias que desarrollan para crecer y competir.

El nivel socioeconómico del hogar y educativo de los padres se calculó a partir de datos de los registros escolares. En los niños y niñas se evaluó el nivel de vocabulario, conocimiento del nombre y sonido de la letra y conciencia fonológica. Se observó un efecto significativo de la zona sobre el nivel educativo de los padres y el socioeconómico. Se obtuvieron correlaciones positivas del nivel socioeconómico y educativo con el conocimiento del nombre y sonido de la letra. Ambas variables contextuales explicaron parte de la varianza en el conocimiento del nombre y sonido de las letras en niños y niñas de 4 años únicamente: 6% y 13% respectivamente. Los resultados sugieren que las variables contextuales influyen en el conocimiento alfabético pre-escolar que presentan los niños y las niñas y que la intervención pedagógica recibida en la escuela promueve el desarrollo de habilidades lingüísticas. Frente a contextos socioeconómicos heterogéneos, la educación escolar es una variable protectora que regula las desigualdades de orden social promoviendo el desarrollo de habilidades lingüísticas precursoras de la lectura al inicio de la escolaridad.

Asimismo se evaluó la evolución de los records de las pruebas de 100 metros en los cuatro estilos, los 400, 800 y 1500 metros libres ambos sexos en pileta de 25 y 50 metros. Se consideró la cantidad de clubes participantes, los nadadores con licencia nacional en los distintos años y las nominaciones para Seleccionados Nacionales en las distintas décadas. No se obtuvo diferencias estadísticamente significativas entre la evolución de los records realizados en pileta de 25 con la de 50 metros. Se comprobó que disminuyó tanto la cantidad de clubes participantes en los torneos desde 1950 hasta el año 2000 como la de nadadores federados. El estudio nos revela que el nivel competitivo de los nadadores se ha elevado por el aumento en las nominaciones a Seleccionados Nacionales. Como conclusión obtuvimos que posiblemente estos valores obtenidos se deban a la evolución en las técnicas de nado y en los métodos de entrenamiento, interrogante que puede servir para próximos estudios y que, en este caso, la cantidad de deportistas no es directamente proporcional a los logros deportivos.------------------------------------------------------------------------------The investigation that we carried out sustains in an exploratory and descriptive study.

The case study tackled comprises the north-eastern extreme of Mendoza province. The , which is the hyperarid spot of the region, severely affected by desertification processes, covering an extent of 10,007 km2, and with 3015 inhabitants, where small goat breeding farms predominate. Previous studies indicate that the major causes of desertification in the area are logging of the native woodland and overgrazing which have led to improper livestock production practices. In response to this, the actions to combat desertification commonly point out the need to "raise awareness" and "build capacities" of the producers by initiating processes of change in the production systems. The proposals insist that, if the current level of pressure on resources is maintained, the already serious poverty conditions will grow worse in the future. Nevertheless, despite the efforts and funds invested, the producers seem to stubbornly persist in their present production strategies and in the dynamics of natural resource use derived from them. How to explain their refusal to consider other production options likely to result in higher profit and better environmental balance? How to explain that they act, at least apparently, against their own benefits? Against the explanations that place the producers' "culture" is the most important problem, the present work seeks to cooperate in clarifying these questions through an analysis of the different rationalities that, held by different actors, converge in the area. By using a mixed methodology, the paper analyse three dimensions: 1- The environmental resource supply, which is the basis of production activities, 2- The income attained by goat production units, and 3- The expenditures they face in terms of

    The La Peña alkaline complex (LPC) of Miocene age (18-19 Ma) lies on the eastern front of the Precordillera (32°41ʹ34ʺS, 68°59ʹ48″W, 1400-2900 m a.s.l.), 30 km northwest of Mendoza city, Argentina. It is a subcircular massif of 19 km2 and 5 km in diameter, intruded in the metasedimentary sequence of the Villavicencio Formation of Silurian-Devonian age. It is the result of integration of multiple pulses derived from one or more deep magma chambers, which form a suite of silicate rocks grouped into: a clinopyroxenite body, a central syenite facies with a large breccia zone at the contact with the clinopyroxenite, bodies of malignite, trachyte and syenite porphyry necks, and a system of radial and annular dikes of different compositions. Its subcircular geometry and dike system distribution are frequent features of intraplate plutons or plutons emplaced in post-orogenic settings. These morphostructural features characterize numerous alkaline complexes worldwide and denote the importance of magmatic pressures that cause doming with radial and annular fracturing, in a brittle country rock. However, in the LPC, the attitude of the internal fabric of plutonic and subvolcanic units and the preferential layout of dikes match the NW-SE extensional fractures widely distributed in the host rock. This feature indicates a strong tectonic control linked to the structure that facilitate space for emplacement, corresponding to the brittle shear zone parallel to the N-S stratigraphy of the country rock. Shearing produced a system of discontinuities, with a K fractal fracture pattern, given by the combination of Riedel (R), anti-Riedel (R‧), (P) and extensional (T) fracture systems, responsible for the control of melt migration by the opening of various fracture branches, but particularly through the NW-SE (T) fractures. Five different pulses would have ascent, (1) an initial one from which cumulate clinopyroxenite was formed, (2) a phase of mafic composition represented by

    This discussion of Argentina covers geography, the people, history and political conditions, government, economy, foreign relations, and relations between the US and Argentina. In 1985, the population of Argentina was estimated to be 30.6 million with an estimated annual growth rate of 1.5%. The infant mortality rate is 34.1/1000, and life expectancy is 70.2 years. Argentina, which shares land borders with Bolivia, Brazil, Chile, Paraguay, and Uruguay, is bounded by the Atlantic and the Antarctic Oceans. Descendants of Italian and Spanish immigrants predominate in Argentina, but many trace their origins to British and West and East European ancestors. In recent years, there has been a substantial influx of immigrants from neighboring Latin American countries. The native Indian population, estimated to be 50,000, is concentrated in the peripheral provinces of the north, northwest, and south. What is now Argentina was discovered in 1516 by the Spanish navigator Juan de Solia. The formal declaration of independence from Spain was made on July 9, 1816. In the late 19th century, 2 forces worked to create the modern Argentine nation: the introduction of modern agricultural techniques and the integration of Argentina into the world economy. Argentina has impressive human and natural resources, but political conflict and uneven economic performance since World War II have impeded full realization of its considerable potential. Yet, it is one of the wealthiest countries in Latin America. Among the reasons for the military coup of March 1976 was the deteriorating economy, caused by declining production and rampant inflation. Under the leadership of the Minister of the Economy, the military government focused attention on those immediate problems, and, in 1978, embarked on a new development strategy focusing on the establishment of a free market economy. There was little improvement in the economy, and a new economic plan was introduced in 1985 which has capped inflation by

    The infill of the Neuquén Basin recorded the Meso-Cenozoic geological and tectonic evolution of the southern Central Andes being an excellent site to investigate how the pattern of detrital zircon ages varies trough time. In this work we analyze the U-Pb (LA-MC-ICP-MS) zircon ages from sedimentary and volcanic rocks related to synrift and retroarc stages of the northern part of the Neuquén Basin. These data define the crystallization age of the synrift volcanism at 223 ± 2 Ma (Cerro Negro Andesite) and the maximum depositional age of the original synrift sediments at ca. 204 Ma (El Freno Formation). Two different pulses of rifting could be recognized according to the absolute ages, the oldest developed during the Norian and the younger during the Rhaetian-Sinemurian. The source regions of the El Freno Formation show that the Choiyoi magmatic province was the main source rock of sediment supply. An important amount of detrital zircons with Triassic ages was identified and interpreted as a source area related to the synrift magmatism. The maximum depositional age calculated for the Tordillo Formation in the Atuel-La Valenciana depocenter is at ca. 149 Ma; as well as in other places of the Neuquén Basin, the U-Pb ages calculated in the Late Jurassic Tordillo Formation do not agree with the absolute age of the Kimmeridgian-Tithonian boundary (ca. 152 Ma). The main source region of sediment in the Tordillo Formation was the Andean magmatic arc. Basement regions were also present with age peaks at the Carboniferous, Neoproterozoic, and Mesoproterozoic; these regions were probably located to the east in the San Rafael Block. The pattern of zircon ages summarized for the Late Jurassic Tordillo and Lagunillas formations were interpreted as a record of the magmatic activity during the Triassic and Jurassic in the southern Central Andes. A waning of the magmatism is inferred to have happened during the Triassic. The evident lack of ages observed around ca. 200 Ma suggests

    Full Text Available This article explores the trajectory of the graphic workers of Mendoza during the military dictatorship of the Argentine Revolution. These workers were recognized as “combative” by members of the labor movement of the period and by the press of the era, despite being a sector that did not play any leading role in the struggles of those years. In order to explain this paradox, this article inquires into the internal dynamics of the organization, its union strategies, and the positions it adopted with respect to other labor organizations and with respect to the dictatorship itself. Through the analysis of union documents—the minutes of Assemblies and Steering Committee Meetings— and interviews of graphic workers of the period, it reveals internal and external aspects of this guild and the graphic trade itself.

    Full Text Available El objetivo del trabajo es generar conocimientos que permitan determinar la influencia del arbolado urbano, público o privado, sobre el potencial solar de los entornos urbano- edilicios de baja densidad del Área Metropolitana de Mendoza (AMM. El estudio de la permeabilidad del arbolado urbano ha sido desarrollado para situaciones típicas del área de Capital, Mendoza, representada por especies como: Plátano 21,80%, Morera 32,7%, Fresno europeo 20,95% y Paraíso 2,72% (Cantón, 1994-2000. Sin embargo para determinar la permeabilidad arbórea de entornos urbanos de baja densidad del AMM, en una primera etapa fue necesario realizar una recolección muestral que permitió identificar la presencia de ejemplares no evaluados como Acer 9,95% y Paraíso sombrilla 8,37%. En una segunda etapa, se elaboró un plan de mediciones para un ciclo anual, sobre un conjunto de 8 ejemplares por especie seleccionada. Los resultados obtenidos indican una reducción de la energía solar disponible, del 52,88% al 75,93% en la estación de invierno y del 85,96% al 98,38 % en verano para Acer y Paraíso Sombrilla respectivamente. El estudio ha permitido avanzar en la determinación del potencial solar en ambientes urbanos considerando la permeabilidad de dos especies arbóreas representativas del AMM.

    Full Text Available Resumen Este trabajo tiene por objetivo proponer un modelo de la organización tecnológica de la producción de cerámica durante el período colonial en Mendoza. La metodología de estudio consiste en el análisis de datos históricos (algunos de ellos, inéditos y arqueológicos para reconstruir la secuencia de producción de cerámica (cadena operativa y los agentes involucrados. Estos datos son interpretados en el marco social y económico en el que se inserta el proceso de producción alfarera. Las evidencias muestran que durante los siglos XVI al XIX funcionaron múltiples talleres con, al menos, dos niveles distintos de organización, y con la participación de distintas tradiciones tecnológicas, lo cual explica la diversidad técnica y composicional del registro arqueológico. La modalidad más antigua, que comenzó con las primeras instalaciones españolas en el siglo XVI, consistió en la producción de cerámica como una actividad accesoria de aquellos asentamientos y de las haciendas vitivinícolas a partir del siglo XVII, con acceso a mano de obra especializada indígena y africana. En tanto que, desde mediados del siglo XVII, comenzaron a funcionar talleres, como el del Carrascal, con producción a gran escala y especializada, principalmente realizada por alfareros africanos, para el abastecimiento del mercado local.

El objetivo del trabajo es evaluar la eficiencia energética y las condiciones de habitabilidad de unidades de viviendas en edificios en altura. Se seleccionaron cuatro casos en la Ciudad-Oasis de Mendoza, Argentina: dos ubicados debajo y dos sobre la copa de los árboles. Se evaluaron envolventes del tipo másica y liviana. Se realizaron durante dos años mediciones higro-térmicas in situ utilizadas para validar modelos mediante el programa de simulación Energy Plus. Se estudiaron medidas de rehabilitación energética y se analizaron comportamientos térmicos y consumos de energía para climatización. Los resultados demuestran que los departamentos debajo la copa de los árboles aprovechan en verano la protección de la arboleda urbana a la radiación incidente (diferencias térmicas del orden de 4°C, y cuentan con temperaturas más elevadas en invierno (diferencias del orden de 3°C. Con la materialidad edilicia mejorada, debajo la copa se logran consumos para climatización mínimos, cercanos a un edificio de energía cero. Asimismo, las viviendas de los edificios másicos demuestran comportamientos térmicos más cercanos al rango de confort respecto a los edificios livianos.

    The Vaca Muerta Formation (early Tithonian-early Valanginian) is a rhythmic succession of marls and limestones, cropping out in the Neuquén Basin, west-central Argentina. This lithostratigraphic unit was traditionally interpreted as basinal to slope deposits. Detailed facies analysis allows to differentiate seven facies associations, representing basinal to middle ramp facies of a homoclinal ramp system prograding westward from the eastern margin, and slope facies attributed to a distally steepened ramp system that progrades eastward from the Andean volcanic arc in the west. Two sequence hierarchies are recognized: five third order depositional sequences, and fifteen fourth order high-frequency sequences. Fluctuations in organic matter content within the Vaca Muerta Formation suggest relationship with depositional sequences, finding the highest values associated with transgressive system tracts. This work represents an important advance in the understanding of the sedimentary and stratigraphic evolution of this exceptional unconventional reservoir. Our sequence stratigraphic approach contributes to the understanding of the relationship between organic matter, facies, and sea-level changes.

El objetivo de este artículo es analizar, en escolares de 4 y 5 años, la relación entre el nivel educativo y socioeconómico del hogar con habilidades lingüísticas precursoras de la lectura. Esta es una investigación de carácter cuantitativo y de profundidad comparativa. Se evaluaron 120 niños y niñas de salas de 4 y 5 años de Jardín de Infantes de escuelas urbanas (n= 60 y urbano-marginales (n= 60. El nivel socioeconómico del hogar y educativo de los padres se calculó a partir de datos de los registros escolares. En los niños y niñas se evaluó el nivel de vocabulario, conocimiento del nombre y sonido de la letra y conciencia fonológica. Se observó un efecto significativo de la zona sobre el nivel educativo de los padres y el socioeconómico. Se obtuvieron correlaciones positivas del nivel socioeconómico y educativo con el conocimiento del nombre y sonido de la letra. Ambas variables contextuales explicaron parte de la varianza en el conocimiento del nombre y sonido de las letras en niños y niñas de 4 años únicamente: 6% y 13% respectivamente. Los resultados sugieren que las variables contextuales influyen en el conocimiento alfabético pre-escolar que presentan los niños y las niñas y que la intervención pedagógica recibida en la escuela promueve el desarrollo de habilidades lingüísticas. Frente a contextos socioeconómicos heterogéneos, la educación escolar es una variable protectora que regula las desigualdades de orden social promoviendo el desarrollo de habilidades lingüísticas precursoras de la lectura al inicio de la escolaridad.

There are different behaviors in each stratum according to each growing zone. It has been observed that in all “oasis” smaller is the holding, higher is the rate of shrinkage. On the other hand the bigger sizes grow and the acreage concentration of these units has increased significantly. Behaviors were clustered according to their path: taking into account its relationship with both zonal and provincial level stratum averages. Areas like the Oasis Sur have suffered a major a regressive process that has involved almost all the strata. The Uco Valley has shown a significant dynamism in units of more than 25 ha, while the small holdings have moved back, but with lower rates than the average of these strata. The Oasis Norte has also been subject to a bipolar process where a significant loss of small vineyards with the rise of new big holdings. Oasis Este is the only one that remains with lower regression rates.

    In this work, the partial results of the potential production of energy, starting from the biomass and the development of the crops, directed to the production of bio-fuels (Colza and Topinamur) in the North irrigation oasis of Mendoza, Argentina within the National Program of Bio-energy developed by INTA is presented. For the evaluation of the bio-energetic potential, derived from the biomass, the WISDOM methodology developed by FAO and implemented by INTA in Argentina was applied with the collaboration of national and provincial governmental entities that contribute local information The study of the potential production and the development of the bio-energetic crops have been carried out with the advising and participation of the experts of INTA of the studied crops. The province of Mendoza has semi-deserted agro-climatic characteristics. The type of soil and type of weather allows the production of great quality fruits and vegetables in the irrigated areas. The four great currents of water conform three oasis; Northeast, Center and South, which occupy the 3.67% of the surface of Mendoza. Today, Mendoza has 267,889 irrigated hectares, but the surface that was farmed by irrigation was near to the 400,000 ha. The climate contingencies, froze and hailstorm precipitations, plus the price instability cause great losses in the productive sector, taking it to the forlornness of the exploitations. The crop setting of these forlornness lands with crops directed to the production of bio-fuels and the utilization of the biomass coming from the agriculture activities and the agro industry (pruning of fruit trees, refuses of olive and vine, remnants of the peach industry, etc.) could assist the access to the energy in the rural areas, stimulating the economical improvement and the development in these communities.

Late Triassic invertebrates, including ammonoids, nautiloids, bivalves, gastropods, brachiopods and corals are restricted to the lower 150 m. Beds between 125-135 m from the bottom yield Choristoceras cf. marshi Hauer, a species found in the Marshi/Crickmayi Zone of Europe and North America, together with loose fragments of Psiloceras cf. pressum Hillebrandt, coeval with the lower to middle part of the Hettangian Planorbis Zone. About 80 m higher are beds yielding Psiloceras cf. rectocostatum Hillebrandt, a species that gives name to an Andean biozone partially coeval with the Johnstoni and Plicatulum Subzones, upper Planorbis Zone. Other fossils recorded in the Rhaetian strata of this section are foraminifers, ostracods and plant remains identified as Zuberia cf. zuberi (Szaj. Freng. and Clathropteris sp. The section was also sampled for conodonts and radiolarians, thus far with negative results. A palaeomagnetic study is underway.

Este acontecimiento marca un punto de inflexión en la historia argentina ya que dio inicio a un período de gran inestabilidad política e institucional caracterizado por la proscripción del peronismo y la alternancia de gobiernos militares y pseudos-democráticos. Debido a su importancia este hecho histórico ha sido objeto de numerosas e importantes investigaciones, realizadas por especialistas argentinos y extranjeros, pero haciendo hincapié fundamentalmente en el orden nacional y descuidando lo acontecido en los espacios provinciales. Es por ello que a través de este trabajo, me propuse reconstruir los acontecimientos históricos que tuvieron lugar en Mendoza desde el estallido del movimiento revolucionario hasta la renuncia del general Perón, y determinar la contribución de ellos en el éxito final del movimiento revolucionario.

    Full Text Available El artículo plantea un análisis comparado entre las políticas habitacionales desarrolladas por dos provincias argentinas: Mendoza y San Luis. La federalización de los recursos del FONAVI en el país, ocurrida en l992, puso fin a una prolongada etapa de política habitacional centralizada en Argentina. El período analizado abarca la década comprendida entre ese año y el 2002. A nivel internacional se consolida el proceso de globalización que, en el terreno de la vivienda, se tradujo en el predominio del enfoque facilitador. Los casos elegidos representan dos modelos diametralmente distintos que, sin embargo, alcanzaron resultados que podrían calificarse de exitosos en el concierto nacional. Mientras el primero se inscribe en el paradigma central-sectorial, el segundo adhiere en forma predominante al enfoque facilitador. El análisis de política comparada ha sido contextualizado en los escenarios político, social, cultural y económico que le dieron marco, sentido y viabilidad a ambos modelos, que marcaron tanto sus fortalezas como sus debilidades y que explican los resultados alcanzados. Vinculación con la formación universitaria: La Cátedra Problemática de la Vivienda se encuentra en la Facultad de Ciencias Políticas y Sociales (U.N.Cuyo e incluye en su programa unidades referidas a política habitacional en Argentina y en la provincia de Mendoza.

La incorporación de un número significativo de inmigrantes a finales del siglo XIX junto a un proceso de reorganización productiva asociado al desarrollo de la industria vitivinícola, implicó cambios en las relaciones sociales y en las condiciones de vida de amplios sectores de la población mendocina. Iniciado el siglo XX, la vitivinicultura se convirtió en la principal actividad productiva de la provincia y la más importante en su rubro a nivel nacional. Los viñateros, productores agroindustriales, industriales bodegueros, contratistas de viñas , etc., fueron constituyéndose en parte de una sociedad cada vez más heterogénea y diversa, producto del desarrollo capitalista que experimentó la región desde el último tercio del siglo XIX y que se insertó en el proceso de incorporación de la economía Argentina al mercado mundial. Este período resulta de suma importancia porque se determinó un sistema productivo en torno a la actividad vitivinícola de la provincia que dio forma al mercado de trabajo regional. En este contexto, la inserción de los trabajadores se dio de una manera muy dispar en el proceso productivo, caracterizado por una alta estacionalidad y una escasa especialización de la mano de obra requerida.The aim of this work is to analyze the changes and continuities during the process of formation of the labor market in the province of Mendoza in the early 1900s. Wide sectors of the Mendoza population saw their life conditions and social interactions change as a result of the absorption of a significant amount of immigrants by the end of 19 th century, together with a restructuring of production connected to the development of the wine industry. Shortly after the turn of the century, wine had become the main productive activity of that

    Full Text Available La escasez de agua constituye un problema de Estado en las tierras secas de la provincia de Mendoza, Argentina. Sin embargo, mientras el gobierno local naturaliza y difunde la escasez como un problema “de todos”, los contrastes en el acceso al agua plantean interrogantes respecto de su universalidad. Por ello, este trabajo busca repensar la escasez hídrica desde una perspectiva multidimensional que amplíe el abordaje biofísico. Específicamente, se busca analizar la mirada oficial respecto de esta problemática para, a partir de allí, comprender la manera en la que esta concepción refuerza y legitima desigualdades hídricas y territoriales en Mendoza. Se recurre a la producción de datos primarios a través de la realización de entrevistas en profundidad a funcionarios y pobladores, al análisis de documentos oficiales y de artículos periodísticos locales.

    Full Text Available Achieving the paradigm of sustainable urban mobility requires institutional capacities, appropriate policies and a regulatory framework that contains them. This work aims to contribute to the knowledge of the regulation of urban mobility in the metropolitan area of Mendoza. To this end, the current mobility regulations are assessed through indicators that are classified into three key areas: institutional and political organization, urban system and financial setup. The purpose is to account for the existence, or not, of regulatory capacities contained in the paradigm of sustainable mobility. Among the results, the absence of a policy of sustainable urban mobility is noteworthy, as well as the lack of sectorial coordination. Also of note is the absence of coordination between the urban planning system and the public transport provision. Lastly, in the financial sector, the results point to a promotion of sustainable transport modes but without such an explicit purpose.

  2. Deciphering the geochemical and mineralogical changes of a Miocene sedimentary basin infill, Mendoza Province, Argentina

    Hunger, Gabriel; Moscariello, Andrea; Ventra, Dario

    2017-04-01

    Sediments deposited in foreland basins are accurate recorders of processes acting at different temporal and spatial scales during orogenic uplift. The effects of allogenic forcing on foreland sedimentation are well known at basin-scale, but uncertainties remain in deciphering and interpreting them at higher resolution, and in differentiating them from the sedimentary changes due to autogenic processes. We present observations on the continental sedimentology and stratigraphy of the Central Argentinian Foreland. The majority of the basin infill is comprised by the Mariño Fm. and La Pilona Fm., which were deposited during the Miocene and cover almost 2000 m of stratigraphy. The large scale stratigraphy trend leads to interpret the entire alluvial system as a large fluvial fan that prograded over the proximal margin of the foreland basin. The basin infill records a continuous sediment supply from the rising Principal Cordillera and the first stages of the uplift of the Frontal Cordillera. The interaction of different allogenic forcing factors, but also autogenic processes, is recorded in the compositional changes of the sedimentary infill. This project aims to provide a detailed reconstruction of paleoenvironmental dynamics and unravel the relative roles of climate and tectonics, using a high-resolution, integrated compositional and sedimentological analysis of the Mariño Formation and the basal part of the La Pilona Formation. The followed approach embodies the use of automated QEMSCAN technology, geochemistry, heavy-minerals and radiogenic isotope analysis. Along 1500 m of stratigraphy we recognize compositional variations related to the evolution of the basin infill due to, at least, 5 phases of non-steady state conditions. Principal component analysis done with the major elements, main mineral phases and heavy minerals allow us to recognize the importance of the weathering and diagenesis in the total compositional variability. The A-CN-K ternary diagram displays low to moderate weathering values (CIA = 45-65) and shows the evolution of the composition towards the illite pole, in agreement with the QEMSCAN results. The evolution of the source rock composition shows a trend towards more mafic sources. La Pilona Fm. is characterized by more scarce composition certainly due to the advance of the thrust front coupled with inputs from the uplifting Frontal Cordillera, a tectonic province feeding the basin with different igneous sources. The integration of heavy mineral and isotopic data to constrain the source area changes will also allow us to have a better understanding of the evolution of the uplifting Andes.

    In the Rio Mendoza valley, five Pleistocene drifts and one Holocene drift are distinguished by multiple relative-age criteria, including surface-rock weathering, development of rock varnish, moraine morphology, soil-profile development, and stratigraphic relationships. Several absolute ages suggest a preliminary chronology. During the oldest (Uspallata) glaciation, a system of valley glaciers flowed 110 km from the Andean drainage divide and 80 km from Cerro Aconcagua to terminate at 1850 m. Drift of this ice advance is older than a widespread tephra dated by fission-track at 360,000 ± 36,000 yr. During the Punta de Vacas advance, ice terminated at 2350 m, while during the subsequent Penitentes advance, the glacier system ended at 2500 m. A travertine layer overlying Penitentes Drift has U-series age of 24,200 ± 2000 yr B.P. The distribution of Horcones Drift, which is inferred to represent the last glacial maximum, delimits an independent ice stream that flowed 22 km down Horcones valley to 2750 m. A later readvance (Almacenes) reached 3250 m. Confluencia Drift is considered to be Neoglacial in age and extends downvalley to 3300 m. The moraine sequence is compared with those studied by Caviedes (1972) along Rio Aconcagua on the Chilean flank of the Andes.

A theoretical ad hoc approach is adopted, conjugating the concepts of innovation systems at sector / regional level with some context considerations like the innovative behaviour of the global and local food industry and a description of the public and private S&T in Argentina. The study is focused in two cases: the wine industry, at the Mendoza province, and the dairy products industry at the centre of the Santa Fe province, both in Argentina. While the winery industry at the province of Mendoza exports differentiated products the dairy industry, at the central basin of the province of Santa Fe, exports commodities leaving differentiated (functional products for the domestic market. These facts determine different dynamics between them, despite of what the established set of relationships is very complex and knowledge intensive in both cases. Also, in both cases the preponderant contribution of the public institutions of science and technology as knowledge and technology source is flagged.

    The town of Motozintla de Mendoza (15o 22' N and 92o 15' W) is located southern Chiapas, Mexico, and it is highly exposed to flood hazards. This community has suffered the impact of two disaster events due to this natural hazard in less than ten years, the first one in 1998 and the second one in 2005. The objective of this research is to assess the level of flood risk in the community of Motozintla. The methodology consisted of four steps: (1) Identification of the level of flood hazard; (2) Vulnerability assessment considering weighted variables according to their level of incidence on the local risk conditions; (3) Preparation of risk matrices for each area exposed to floods; and 4) Cartographic representation and spatial analysis of the results. We obtained a Geographical Information System (GIS) map for each group of analyzed vulnerabilities (structural, public services, socio-economic, existing plans in case of contingencies, and risk perception) and one map associated to global vulnerability (overposing of all estimated vulnerabilities). These maps demonstrates that the local conditions of structural vulnerability have a high incidence in the generation of risk, differing from the lack of public basic services, which although unfavorable for the population, it is not a deciding factor for preserving life or housing. Another interesting result is that the lack of preparation of the community to face a disaster generates a higher risk level than the other analyzed socioeconomic conditions. The global vulnerability allowed us to determine with greater detail the flood risk levels in the community. Our results indicate that the area in Motozintla with the highest level of flood risk is located in the margins of the Xelajú river, particularly the region that was flooded in 2005, which is precisely the area where the rivers Xelajú, Allende and La Mina meet and the river flow increases. Unfortunately, the northeasters part of this zone had been populated by people

Estas prácticas políticas fueron acompañadas por campañas publicitarias que apuntaban a identificar consumo de productos nacionales con una nueva versión del patriotismo. Este artículo se propone realizar algunos aportes sobre esa cuestión, centrándose en las formas en que el Estado nacional -a través del Ministerio de Agricultura- y la dirigencia política y empresarial de la provincia de Mendoza elaboraron la imagen de la Argentina frutícola, productora de uvas de mesa, naranjas y manzanas para el consumo interno, a la vez que la promovían proyectándola como un novedoso renglón de las exportaciones argentinas.The closing of international markets for Argentine agrarian production forced the Government to implement a series of alternative measures such as production and commerce public regulations, bilateral treaties and the rediscovery of possibilities of the domestic market for national products. Those political measures were supplemented by a variety of advertising campaigns aimed at identifying the consumption of domestic products with a new way of patriotism. This paper aims to make contributions to this matter, focusing in the ways in which both the national government -through its agriculture ministry- and the political and corporate leaderships in the province of Mendoza composed the image of Argentina as an important producer of grapes, oranges and apples, while at the same time they stimulated fruit as a new source of the country international commerce.

Así, migran a la ciudad de Mendoza jóvenes becarios, los cuales interactúan, en mejores condiciones de acceso a bienes y servicios, con un nuevo entorno sociocultural. Hacen realidad y practican en la ciudad su pertenencia a las categorías étnica, campesina y estudiantil. Se habla de "origen" en este artículo como un hacer situado en lugar de considerarlo como el hecho de "haber nacido en". Describiendo la experiencia intercultural de los becarios, dos ideas son postuladas. En primer término, el origen se actúa día a día (es una performance ante tribunales informales, utilizando un conocimiento práctico de reglas comunes. En segundo lugar, el origen se merece según la labor y el esfuerzo del actor. De este modo, en la experiencia de los becarios mendocinos, ser étnico o campesino es más bien un asunto del hacer en situaciones concretas con otros, antes que un hecho de nacimiento, de esencia o de herencia.Similar to affirmative action politics in North America, the University of Cuyo, in Argentina, provides scholarships and quotas since 2003 to indigenous and peasant students.

    Full Text Available La producción de carbón de residuos de aserraderos de la especie Aspidosperma quebracho-blanco en la provincia del Chaco, Argentina, se realiza por medio de hornos convencionales, tipo media naranja con un rendimiento en peso de carbón de 25 % y un rendimiento en carbono fijo de 74 %. El objetivo del presente trabajo fue proponer una alternativa más eficiente del uso de residuos de aserraderos para optimizar el rendimiento en peso de carbón y el rendimiento en carbono fijo. Para ello, se procedió a fabricar carbón por destilación seca, de acuerdo a un diseño experimental compuesto controlando los siguientes parámetros: velocidad de calentamiento entre 60 y 120 ºC·h-1 y temperatura final de carbonización entre 450 y 550 ºC. Los resultados arrojan un rendimiento en peso de carbón del 48 % trabajando con una velocidad de calentamiento y temperatura final de carbonización baja, disminuyendo este rendimiento a un 36 %, cuando se trabaja a velocidades de calentamiento y temperaturas finales de carbonización, altas. En lo que respecta a rendimiento en carbono fijo, su comportamiento es de manera inversa en referencia a las variables antes mencionadas, pero siempre con un rendimiento superior al 82 %.

Argentina has a long tradition regarding this kind of tourism, mainly wine tourism, reflected in the National Wine Festival held since 1936 en the province of Mendoza. By the end of the 20th century culinary tourism was brought into the national tourism plan and it was the start for the private sector to develop own initiatives in order to develop small towns into culinary attractions for visitors. This article presents the results of a study undertaken in order to get acquainted with the visitor profile and motivations for visitors to Tomás Jofré during Sun-days.

  2. El sistema lacustre de la Formación Mollar en el depocentro triásico de Santa Clara (provincia de Mendoza, Argentina The lacustrine system of the Mollar Formation in the Triassic Santa Clara Depocenter (Mendoza Province, Argentina

    Full Text Available El depocentro triásico de Santa Clara, Cuenca Cuyana, se caracteriza por espesos depósitos generados en ambiente lacustre. Uno de ellos, con un registro de más de 345 m, corresponde a la Formación Mollar. El tramo inferior a medio está caracterizado por una monótona sucesión de lutitas bituminosas acumuladas por decantación suspensiva en el 'off shore' anóxico de un cuerpo lacustre hidrológicamente cerrado y que muestra alto contenido de materia orgánica amorfa de origen algal y de restos de plantas terrestres muy degradadas junto a sulfuros de hierro autígenos. Intercalan areniscas finas debidas a corrientes de turbidez diluidas y carbonatas estromatolíticos. En esta sucesión se definen ciclos granocrecientes de pequeña escala (PACs que se atribuyen a episodios de expansión-retracción lacustre controlados por cambios climáticos. Asociaciones de facies heterolíticas representan los depósitos de la transición entre los ambientes de 'nearshore' y 'offshore' lacustre. La sección superior de la Formación Mollar se compone de sucesiones pelíticas con profusa bioturbación que sugieren mayor oxigenación del sustrato y se asignan a ambiente de costa afuera de un sistema lacustre holomíctico hidrológicamente abierto. Intercalan areniscas producto de flujos hiperpicnales. Depósitos de areniscas con abundantes trazas fósiles y estructuras de olas y flujos unidireccionales, representan a sectores marginales del ambiente lacustre. Además de los ciclos de alta frecuencia, en la Formación Mollar se definen tres secuencias asimétricas de mayor escala atribuidas a episodios mayores de expansión-contracción lacustre debidos a la interacción entre factores climáticos y tectónicos. El diseño de superposición granocreciente de la Formación Mollar y la gradual transición a depósitos fluviales de la sobreyacente Formación Montaña refleja asimismo una constante reducción del espacio de acomodación sedimentaria en el depocentro de Santa Clara a medida que se produjo la acumulación de los depósitos estudiados.The Triassic Santa Clara depocenter, Cuyo Basin, is characterised by thick fine-grained deposits formed in lacustrine systems. One of them, represented by the Mollar Formation, exceeds the 345 m. The lower to middle section of this unit is dominated by a monotonous succession of black shales having a high content of amorphous organic matter produced by algae and highly degraded plant remains. These deposits were formed by suspensión fallout in the anoxic 'offshore' sector of a hydrologically closed lake. Thin and fine-grained turbiditic beds and stromatolitic carbonates are intercalated in the fine-grained succession. Small-scale coarsening-upward cycles (PACs are attributed to episodes of lake expansion-retraction driven by climate change. A facies association composed of an heterolithic package represents the deposits of the transition between 'nearshore' and 'offshore' settings. The upper section of the Mollar Formation essentially consists of bioturbated mudstones suggesting a greater oxygenation of the substrate. They are assigned to the 'offshore' environment of a holomictic hydrologically open lake system. Sporadic hyperpycnal flows are documented by intercalations of sandy turbidites. Bioturbated sandstone beds with primary structures indicative of both normal and storm wave action and unidirectional flows, represent the marginal deposits of the lacustrine system. In addition to the high-frequency cycles, three larger scale asymmetrical sequences are identified in the Mollar Formation. These sequences suggest episodes of major expansion-contraction of the lake system due to the interaction between climatic and tectonic factors. The overall shallowing up stacking pattern of the Mollar Formation and the gradual transition to fluvial deposits of the overlying Montaña Formation reflects a steady reduction of accommodation space in the Santa Clara depocenter during the accumulation of the studied succession.

    Full Text Available El análisis de la evolución de Mendoza en el siglo XVII permite diferenciar las características de un asentamiento en la periferia de aquellas características que corresponden a una sociedad de frontera. Fundada en 1561 en la periferia imperio español en América a principios del siglo XVII, Mendoza era una comunidad con escasa población, con reducido comercio y de lento desarrollo urbano; todas características de las colonias periféricas. A lo largo de la primera parte del siglo XVII, sin embargo, Mendoza se fue configurando como una sociedad de frontera. Las causas de este devenir frontera se relacionan con la revuelta araucana y con las consecuencias del establecimiento de la frontera geográfico-militar en el río Biobio. El trabajo comienza con una revisión de los términos frontera y periferia tal como se encuentran empleados en los análisis de algunos autores representativos de la historiografía sobre fronteras para las Américas. Luego se reconstruye la evolución de periferia a frontera en Mendoza; un proceso que comenzó varias décadas después de su fundación en 1561. Tal fundación no estuvo guiada por la necesidad de consolidar o de proteger una zona de frontera, de modo que no fue fundada ni como presidio ni como misión, que son las típicas instituciones de frontera y que encontramos en numerosas fronteras del imperio español, como ser en la Florida y en el norte de México. A fines del siglo XVI Mendoza fue fundada como uno de los tantos asentamientos que permitirían a los españoles seguir avanzando en la conquista y colonización de nuevos territorios. Sin embargo, la revuelta araucana de 1598-1599 provocó el quiebre de tal desenvolvimiento de la conquista porque truncó la esperanza de una futura expansión española hacia el sur. Más allá del fiasco militar de la derrota de Curalaba, la rebelión nativa obligó a la coronaa establecer un ejército profesional de alrededor de 2.000 hombres, cuya permanencia

    Based on gravimetric and magnetic data, together with isostatic and elastic thickness analyses, we modeled the crustal structure of the area. Information obtained has allowed us to understand the crust where the SRB and the Payenia volcanic province are located. Bouguer anomalies indicate that the SRB presents higher densities to the North of Cerro Nevado and Moho calculations suggest depths for this block between 40 and 50 km. Determinations of elastic thickness would indicate that the crust supporting the San Rafael Block presents values of approximately 10 km, being enough to support the block loading. However, in the Payenia region, elastic thickness values are close to zero due to the regional temperature increase.

    A karyological study of some populations of the Odontophrynus occidentalis group (2n = 22) from Argentina is reported. Ammoniacal silver (Ag-AS) and alkaline Giemsa (CBG) staining have been performed on specimens from La Rioja, Mendoza, Malargue, Tamelen, Tapiluque, Valcheta, and Meseta de Somuncura. All populations showed active ribosomal cistrons (NORs) on chromosome 11. Some metaphases of three specimens from Mendoza and five from La Rioja also showed bands on 9. Centromeric and telomeric C-bands were common to all populations, and a block of heterochromatin on both sides of the centromere of 2 was remarkable in all but the La Rioja populations. The specimens from La Rioja showed a similar block of heterochromatin on the short arm of 1. Taxonomic studies of several specimens from these localities revealed differences in larval development, glandular pattern, the size of specimens, etc. As a whole, biological as well as karyological features suggest that the isolated population at La Rioja is a separate entity, at the species level, as described elsewhere.

    Propolis is a resinous substance collected by honeybees from various plant sources. The composition of propolis depends on the type of vegetation and the area of collection. We examined the radical-scavenging activity of propolis from the following regions of Argentina: Mendoza, Rio Negro, La Pampa, and Entre Rios. Ethanol extracts of propolis (EEP) were prepared and their 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activities were evaluated. Furthermore, the major constituents in EEP were identified by HPLC with photodiode array (PDA) detection, and each component was quantitatively analysed. Almost all of the propolis samples, except La Pampa, had radical-scavenging activity. Propolis with strong radical-scavenging activity contained large amounts of antioxidative compounds, such as caffeic acid, ferulic acid and caffeic acid phenethyl ester.

    Full Text Available The cacicazgo, or indigenous lordship, was a pivotal institution in colonial Mexican Indian pueblos. Caciques, or Indian nobles, played a role, both in the largely indigenous world of the pueblo and in the regional economy that was dominated by Spaniards. This subject of this essay is the analysis of the evolution and daily operation and of a cacicazgo from the Indian settlement of Tepexí de la Seda near the city of Puebla de los Ángeles and the life of its caciques in the sixteenth and seventeenth centuries. In the sixteenth century the cacicazgo was in upheaval because of discord between the cacicazgos and their dependent Indians. A number of long-running accounts from the 1620s record in detail the daily operations of the cacicazgo of Doña Ana de Santa Bárbara of the Mendoza family, thus illustrating how caciques negotiated their positions and coped with their lives and the changes in it.   Resumen: Un cacicazgo colonial: los Mendoza de Tepexí de la Seda en el siglo 17 El cacicazgo, o señorío indígena, fue una institución fundamental en los pueblos indios de México colonial.

    There is limited data on immunity against varicella-zoster virus (VZV) in adults in different parts of Argentina, and it is not known which VZV strains are circulating in Argentina. The objectives of this study were as follows: (i) to evaluate seroprevalence of varicella among adults, assessing the accuracy of clinical history and determining the sociodemographic factors associated with seropositivity; and (ii) to determine the VZV strains circulating in Argentina. A cross-sectional serological survey enrolling 2,807 women aged 15 to 49 years attending public health-care settings in four cities in Argentina (i.e., Buenos Aires, Salta, Mendoza, and Rosario) and one rural area was conducted from August to November 2002. Specimens for identification of VZV strains were obtained from vesicular lesions from 13 pediatric patients with varicella from different areas of the country. PCR amplification was used for genotyping. The overall seroprevalence of varicella antibodies was 98.5% (95% confidence interval, 98.0 to 98.9), ranging from 97.2% in central Buenos Aires to 99.3% in southern Buenos Aires and Salta. Varicella seroprevalence increased with age. Crowding and length of residence in the same place were associated with seropositivity. The positive predictive value of varicella history for immunity to varicella was 99.4%; however, the negative predictive value was 2.5%. The European genotype was identified in all viral specimens. In Argentina, seroprevalence in women more than 15 years old was high regardless of the area of residence. Negative or uncertain varicella history was not a good predictor of immunity. VZV genotype was stable in all areas of the country.

    2012-12-01

    Full Text Available From the early nineteenth century, Spanish physicians started to sense a «threat» to the language of medicine which they used, due in part to the large number of foreign terms they were forced to import from other languages, particularly French. Many voices emerged to denounce this situation and propose potential solutions such as those which would be derived from the creation of a terminological dictionary which would fix precise meanings for medical terms. It was Manuel Hurtado de Mendoza who eventually dared to take on this task and develop the first modern terminological dictionary of medicine in Spanish. The intention of this paper is to present from a philological viewpoint the process by which a lexicographical work that deserves to be better known and used in studies on historical lexicography came to be constructed.

Se procesaron muestras seriadas, fecales y de escobillado anal, mediante técnicas de concentración. Los resultados se analizaron por sexo, intervalo de edad y provincia. Se calcularon la frecuencia de parasitosis (monoparasitosis y parasitosis múltiple, la riqueza de especies y el coeficiente de similitud de Sørensen. Resultados Misiones presentó la mayor frecuencia de niños parasitados y Chubut la menor (82,0% vs. 38,4%; p ˂ 0,01. El número de especies fue mayor en Misiones y Buenos Aires y menor en Chubut y La Pampa. Los varones estuvieron más parasitados que las mujeres solo en Buenos Aires. Las mayores frecuencias se encontraron en los preescolares de Buenos Aires y los escolares de Mendoza y Misiones (p < 0,05. La monoparasitosis fue más frecuente en Chubut (67,9% y las parasitosis múltiples en Formosa (69,2%. Las especies más frecuentes en la mayoría de las provincias fueron Blastocystis sp. y Enterobius vermicularis. De los geohelmintos, Misiones presentó la mayor frecuencia (23,3% y Mendoza la menor (0,6%; no se hallaron en Chubut, La Pampa y Salta. Buenos Aires, Formosa y Misiones presentaron una composición de especies similar, al igual que Chubut y La Pampa. Conclusiones Las frecuencias de parasitosis en Argentina responden al complejo mosaico de variabilidad climática y socioeconómica del país y revelan una tendencia descendente de norte a sur y de este a oeste.

    Full Text Available El trabajo apunta al estudio de los ecosistemas como entidades complejas y jerárquicas, desde el punto de vista escalar y de su diversidad estructural, en el norte de la provincia de Mendoza, hasta los 34o de latitud sur. Se enfoca el estudio espacial jerárquico desde diferentes escalas de análisis: micro, meso y macroescala. La macroescala (macroecositema equivale a los biomas de Mendoza, (Altos Andes y Monte; la mesoescala, a los ecosistemas definidos por la diferenciación geomorfológica (mesoecosistema; y la microescala, a los sub-ecosistemas que surgen de las diferenciaciones topográficas y edáficas vinculadas con las formaciones vegetales y su ambiente (microecosistema. Para este trabajo se aplican los métodos: geográfico y el de factores de control, ambos conducen el análisis y la identificación de los ecosistemas. Las diferenciaciones jerárquicas espaciales de los ecosistemas están basadas en: el clima zonal, las unidades geomorfológicas que lo modifican; la topografía y el suelo con su disponibilidad de agua, modificadores del microclima. Los objetivos generales se basan en la identificación y localización de los ecosistemas jerárquicos y su análisis multiescalar integrado. Las hipótesis planteadas afirman que, en las escalas de ecosistemas, el clima es el denominador común que organiza la distribución de los mismos; y que existen agentes degradadores en todos los niveles de análisis. En el análisis, se aplican los métodos deductivo-inductivos vinculando las escalas jerárquicas de los ecosistemas y los estudios de casos. Con este trabajo se pretende profundizar el conocimiento de la complejidad de los ecosistemas mendocinos, con un enfoque original.

    Full Text Available Hacia 1890 la provincia de Mendoza se consolidó como núcleo de la región vitivinícola argentina. Noobstante, ante las cíclicas coyunturas críticas del sector se buscaron alternativas para promover otrasindustrias de base agrícola, como la olivicultura y la fruticultura. Esta última alcanzó notoriedad a partirde la década de 1930 con un incremento de la producción de frutas para consumo en fresco y en con-servas; y desde entonces, ha secundado la elaboración de vinos. Sin embargo, es posible rastrear indicios de esta actividad desde finales del siglo XIX. Así, en este ar-tículo indagaremos sobre los orígenes de la industrialización frutícola en la provincia, con miras a detec-tar posibles fomentos estatales a la actividad e identificar cuáles fueron los actores que tempranamentese volcaron a la fase industrial de la fruticultura.

    Full Text Available In Argentina, family medicine begins to appear in the sixties. It has followed along with the movement in favour of the specialty in Latin America and its existence in important areas is strongly related to men and women who have defended and promoted the specialty. It is present in many Ministry of Health programs; however, its development has depended and still depends on each jurisdiction and upon the coordination between the subsystems and political regions. The professional associations that bring together general practitioners and family doctors in Argentina.FAMG (General Medicine Federation of Argentina and FAMFYG (Argentina Federation of Family and General Medicine, have consolidated healthcare teams, elevated the scientific level of both family doctors in training as well as already certified practitioners, and have become acknowledged entities that certify the specialty and accreditation of teaching centers. Insertion in universities, provinces and private providers still poses challenges.

    Nutritional transition has been described in various countries, each showing inherent characteristics. Furthermore, different patterns also appear within the same country. To compare the nutritional status of schoolchildren, of both sexes, living in two Argentine cities with different urban and environment characteristics, from the perspective of nutritional transition. The sample comprised 5355 children (6-13 years) living in Puerto Madryn (Chubut) and General Alvear (Mendoza), Argentina. Weight and height were transformed into Z-scores according to NHANES I- II; underweight, stunting and wasting defined by - 2 SD and overweight and obesity calculated according the cut-off proposed by IOTF. Prevalences of nutritional status were estimated. Comparison of the two cities revealed significant χ² values for the indicators of nutritional status analysed. Puerto Madryn had higher prevalences of overweight and obesity. General Alvear exhibited higher stunting and underweight values. The cities studied are in different stages of nutritional transition. Puerto Madryn is undergoing growing industrialization and urbanization and thus exhibits characteristics typical of an 'obesogenic' environment. General Alvear, a less complex urban centre, where some cultural patterns related to an agrarian way of life appear to have been retained, is situated at a less advanced stage.

    Full Text Available Erythromycin (ERY resistance in Streptococcus pyogenes has recently emerged as a problem of growing concern all through the world. We are presenting the comparison of results of the continuous surveillance of erythromycin resistance in S. pyogenes performed since 1989 in the Hospital de Pediatría J.P.Garrahan of Buenos Aires City, with independently observed rates in other five centers of Buenos Aires and seven centers of six other Argentinian cities, obtained between 1999 and 2001. A significant increase of erythromycin resistance was observed among S. pyogenes isolated in the Hospital Garrahan (6.6% in 1998-1999 to 9.9% in 2000. Similar trends were also detected in other centers of other Argentinian cities when recent data were compared to results of a multicenter study performed in 1995. However, lower rates of resistance were recorded in Mendoza, Cipolletti and Neuquén in comparison with data of 1995, 1998 and 1998 respectively. The reason of such decreasing resistance rates deserves to be investigated. The average of ERY-resistance rates obtained in the surveyed centers was 6.7% (range 0.5 - 14.1%. Control of antimicrobial use should be performed to warrant the future effectiveness of macrolide antibiotics regarding the positive association between use and resistance. These results also suggest that susceptibility tests for macrolides should be performed whenever S. pyogenes is isolated in Argentina.La resistencia a la eritromicina en Streptococcus pyogenes ha emergido en los últimos tiempos como un problema creciente en todo el mundo. En este trabajo se presenta la comparación de los resultados de la vigilancia continua de la resistencia a la eritromicina que se viene realizando en el Hospital de Pediatría J.P.Garrahan de Buenos Aires desde 1989, con resultados independientes de otros cinco centros de la ciudad de Buenos Aires y siete de otras seis ciudades argentinas, obtenidos entre 1999 y 2001.

    Full Text Available La provincia de Mendoza posee una rica fauna de lagartos pertenecientes a las familias Leiosauridae, Liolaemidae, Teiidae, Scincidae y Gekkonidae. Algunos son propios del Monte, Puna, Payunia o región andina, mientras que otros poseen una amplia distribución, ocupando dos o más ecosistemas. El objetivo de este trabajo fue actualizar la lista lacertofaunística de la provincia y determinar las áreas de mayor riqueza de especies en relación a estos cuatro tipos de ecosistemas. Se utilizaron datos de procedencia de 43 especies de lagartos a partir de colecciones herpetológicas y de bibliografía. Las localidades fueron georreferenciadas y mapeadas. Una primera estimación de las áreas de mayor riqueza fue realizada sobre la base de las distribuciones de acuerdo a los puntos de colecta. En un segundo análisis, se generaron modelos predictivos de distribución utilizan-do 26 variables ambientales. Estas áreas potenciales fueron superpuestas a fin de obtener el número de especies en cuadrículas de 4,6 km x 4,6 km. Los resultados de ambos métodos indican que la mayor riqueza de especies se encuentra en la Payunia, probablemente en relación a la mayor heterogeneidad ambiental de la zona, ya que es considerada un área ecotonal entre la región fitogeográfica de la Patagonia y el Monte. Un análisis de similitud (Índice de Morisita demuestra que la similitud entre ecosistemas en cuanto a la composición de especies es baja, conformándose dos grupos: el Monte y Patagonia por un lado, y el ecosistema Andino y Puneño por otro.

    Full Text Available Due to its geographical location, the community of Motozintla de Mendoza (Motozintla in the State of Chiapas, Mexico, is continuously exposed to the impact of natural hazards. In this work, we assessed the flood risk of Motozintla considering the structural, socioeconomic, organizational, and global (structural, socioeconomic, and organizational vulnerabilities. In addition, we also measured the local risk perception. Spatial maps were generated to determine the most vulnerable and risk areas of this community. Our results indicate that the population has a high level of risk to flooding mainly because (1 the majority of the local houses has high structural vulnerability; (2 a high percentage of the families has a daily income less than the official Mexican minimum wage and lacks of basic public services as well as of proper social security services; (3 most of the community does not know any existing Civil Protection Plan; and (4 the community organization for disaster mitigation and response is practically non-existent. For these reasons, we believe that it is necessary for local authorities to establish in the short-term, preparedness, mitigation and response plans as well as land-use measures to reduce the risk to floods in Motozintla.

    A proper representation of dust sources is critical to accurately predict atmospheric particle concentrations in regional windblown dust simulations. The Weather Research and Forecasting model with Chemistry (WRF/Chem) includes a topographic-based erodibility map originally conceived for global scale modeling, which fails to identify the geographical location of dust sources in many regions of Argentina. Therefore, this study aims at developing a method to obtain a high-resolution erodibility map suitable for regional or local scale modeling using WRF/Chem. We present two independent approaches based on global methods to estimate soil erodibility using satellite retrievals, i.e. topography from the Shuttle Radar Topography Mission (SRTM) and surface reflectance from the Moderate Resolution Imaging Spectroradiometer (MODIS). Simulation results of a severe Zonda wind episode in the arid central-west Argentina serve as bases for the analysis of these methods. Simulated dust concentration at surface level is compared with particulate matter measurements at one site in Mendoza city. In addition, we use satellite aerosol optical depth (AOD) retrievals to investigate model performance in reproducing spatial distribution of dust emissions. The erodibility map based on surface reflectance from MODIS improves the representation of small scale features, and increases the overall dust aerosol loading with respect to the standard map included by default. Simulated concentrations are in good agreement with measurements as well as satellite derived dust spatial distribution.

    Background The Mediterranean fruit fly Ceratitis Capitata (DIPTERA: Tephritidae) is a major agricultural pest in Argentina. One main cause for the success of non-contaminant control programs based on genetic strategies is compatibility between natural and laboratory germplasms. A comprehensive characterization of the fruit fly based on genetic studies and compatibility analysis was undertaken on two founder populations from the provinces of Buenos Aires and Mendoza, used in pioneering sterile male technique control programmes in our country. The locations are 1,000 km apart from each other. Methodology/Principal Findings We compared the genetic composition of both populations based on cytological, physiological and morphological characterization. Compatibility studies were performed in order to determine the presence of isolation barriers. Results indicate that the Buenos Aires germplasm described previously is partially different from that of the Mendoza population. Both laboratory colonies are a reservoir of mutational and cytological polymorphisms. Some sexual chromosome variants such as the XL and the YL resulting from attachment of a B-chromosome to the X-chromosome or Y-chromosome behave as a lethal sex-linked factor. Our results also show incompatibility between both germplasms and pre-zygotic isolation barriers between them. Our evidence is consistent with the fact that polymorphisms are responsible for the lack of compatibility. Conclusions The genetic control mechanism should be directly produced in the germplasm of the target population in order to favour mating conditions. This is an additional requirement for the biological as well as economic success of control programs based on genetic strategies such as the sterile insect technique. The analysis of representative samples also revealed natural auto-control mechanisms which could be used in modifying pest population dynamics. PMID:19252742

    Full Text Available Estudio exploratorio descriptivo con diseño no experimental, longitudinal, retrospectivo que analiza los cambios producidos en el potencial atlético mendocino desde 1973 hasta 2001. Los resultados obtenidos por la aplicación de la prueba estadística “t” student, significativamente inferiores entre la media del potencial atlético entre el 2000-2001, respecto de la década del 80 (prueba “t” 80/00 = 0,0423. No sucedió lo mismo al compararlos con las décadas del 70 y 90 que registraron entre sí valores similares en sus rendimientos atléticos (“t” 70/00 = 0,3995 y “t” 90/00 = 0,2013. Se concluyó que la diferencia significativa en el rendimiento atlético provincial se produjo al comparar la década del 80 con los años 2000 y 2001. Por lo tanto se rechazó la Hi y se aceptó la H alternativa. Se midieron las variables que influyeron sobre la evolución de este potencial, concluyendo que su disminución tiene relación con el estado que presentan las pistas en uso, insuficientes elementos atléticos, escasa cantidad de profesores especialistas, déficit en la administración de recursos físicos y humanos de los responsables del atletismo federado y falta de proyectos que canalicen la cantidad de jóvenes que compiten en instancias escolares y no ingresan al circuito federado.-------------------------------------------------------------------------Descriptive exploratory study with non experimental longitudinal retrospective design that analyzes the changes in the athletic potential of Mendoza’s population from 1973 to 2001. The results obtained by the application of the "t" student statistic test are significantly lower for the average athletic potential between 2000 and 2001, compared with the decade of the 80s (t-test 80/00 = 0.0423. It was not the same when compared to the decades of 1970 and 1990, which showed similar values to each other in their athletic performance ("t" 70/00 = 0.3995 and t = 0.2013 90/00. The conclusion was that the significant difference in provincial athletic performance was obtained when comparing the decade of the 80s with the years 2000 and 2001. Thus, the Hi was rejected and the alternative H was accepted. The variables that influenced the evolution of this potential were measured, concluding that its decline is related to the state of the tracks in use, insufficient athletic items, lack of specialist teachers, a deficit in the administration of physical and human resources by those responsible for the athletics federation and a lack of projects to channel the number of young people competing at school level that fail to enter the federate circuit.

    The community of Motozintla de Mendoza is located in the State of Chiapas, México (15' 22' N and 92' 15' W) near to the international border with Guatemala. Due to its location, this community is continuously exposed to many different hazards. Motozintla has a population of 20,000 inhabitants. This community suffered the impact of had two disasters recently. In view of these scenarios we carried out the present research with the objective quantifying the vulnerability of this community. We prepared a tool that allow us to document the physical vulnerability conducting interviews with people in risk situation. Our tool included the analysis of five elements: household structure and public services, socioeconomic characteristics, community preparation for facing a disaster situation, and risk perception of the inhabitants using a sample statistically significant. Three field works were carried out (October and November 2009, and October 2010) and 444 interviews were registered. Five levels of vulnerability were considered: very high, high, middle, moderate and low. Our region of study was classified spatially and the different estimated levels of vulnerability were located in geo referenced on maps. Our results indicate that the locality has a high level of physical vulnerability because about 74% of the population reports that their household had suffered damages in the past; 86% of the households present low resistance building materials; 70% of the interviewed families has a daily income under five to fifteen dollars; 66% of population does not know any existing Civil Protection Plan; 83% of the population considers that they live in a high level of risk due to floods; finally, the community organization is practically nonexistent. In conclusion, the level of vulnerability of Motozintla is high due to the many factors to which is exposed, in addition, to the structural, socioeconomic and cultural characteristics of their inhabitants.

    Full Text Available RESUMEN: Alfonso Hojeda fue un notable canonista sevillano que en 1576 publicó en Venecia un libro acerca de los beneficios eclesiásticos. La obra se divide en dos partes: la primera está dedicada a argumentar en contra de la pluralidad de beneficios en una misma persona, de acuerdo con los decretos tridentinos de reforma, mientras la segunda trata en cambio de la compatibilidad de beneficios mediante dispensa papal. Los propios términos en que se manifiestan las dos partes ya están indicando las contradicciones en que ha de moverse el autor, difíciles de salvar. La doctrina de la causa es, además de la distinción entre órdenes normativos, la principal herramienta conciliatoria para Hojeda. El papa está desligado del derecho positivo o humano, pues de otro modo no podría dispensar, o privilegiar, mas sólo puede hacerlo con justa causa.ABSTRACT: Alfonso Hojeda de Mendoza was an outstanding canonist that in 1576 published a book in Venice on the eclesiástica benefits. The book is divided into two parts: the first one is devoted to argue against the plurality of benefits in the same person, according to Trento's decrees, while the second one deals, however, with the compatibility of benefits by the Pope's dispense. The own terms in which both parts are expressed reveal the contradictions, in which the author must move, always difficult to avoid. The doctrine of the cause, as well as the distinction among normative orders, is the main conciliatory tool for Hojeda. The Pope is unlinked to human or positive right, otherwise he could not dispense or privilege, however he can only do it for a just cause.

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

    QUBIC (QU Bolometric Interferometer for Cosmology) is an experimental cosmology project to measure the modes in the polarization of the cosmic background radiation (CBR), the fossil relic that reveals the properties at the Universe 380,000 years after the Planck Era. Discovery of the CBR in 1964 and measurement of tiny temperature anisotropies in 1992 were major breakthroughs in our understanding of the Universe. The next challenge is to measure the polarization of the CBR accurately enough to detect modes that would reveal the existence of primordial gravitational waves produced in the first stages of the Planck Era and probe inflation theory, that assumes an accelerated expansion during the first seconds. The mode signal is however extremely weak and its measurement requires complex instruments. The QUBIC collaboration has developed the concept of interferometric bolometry, that brings together the sensitivity of bolometric detectors with the control of systematic effects provided by interferometry. QUBIC is an international collaboration involving several universities and laboratories in France, Italy, United Kingdom and USA. Recently, Argentina has suggested Alto Chorrillo (Salta), as candidate site for the installation of the experiment, next to the LLAMA site. Here we describe the scientific objectives and the main features of the experiment and we detail the process through which the international collaboration decided to install in Argentina its first module as well as the challenges for our country in this project.

    2018-01-01

    The aim of this work is to obtain an index for predicting the probability of occurrence of zonda event at surface level from sounding data at Mendoza city, Argentine. To accomplish this goal, surface zonda wind events were previously found with an objective classification method (OCM) only considering the surface station values. Once obtained the dates and the onset time of each event, the prior closest sounding for each event was taken to realize a principal component analysis (PCA) that is used to identify the leading patterns of the vertical structure of the atmosphere previously to a zonda wind event. These components were used to construct the index model. For the PCA an entry matrix of temperature ( T) and dew point temperature (Td) anomalies for the standard levels between 850 and 300 hPa was build. The analysis yielded six significant components with a 94 % of the variance explained and the leading patterns of favorable weather conditions for the development of the phenomenon were obtained. A zonda/non-zonda indicator c can be estimated by a logistic multiple regressions depending on the PCA component loadings, determining a zonda probability index \\widehat{c} calculable from T and Td profiles and it depends on the climatological features of the region. The index showed 74.7 % efficiency. The same analysis was performed by adding surface values of T and Td from Mendoza Aero station increasing the index efficiency to 87.8 %. The results revealed four significantly correlated PCs with a major improvement in differentiating zonda cases and a reducing of the uncertainty interval.

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

    Titanosauria is an exceptionally diverse, globally-distributed clade of sauropod dinosaurs that includes the largest known land animals. Knowledge of titanosaurian pedal structure is critical to understanding the stance and locomotion of these enormous herbivores and, by extension, gigantic terrestrial vertebrates as a whole. However, completely preserved pedes are extremely rare among Titanosauria, especially as regards the truly giant members of the group. Here we describe Notocolossus gonzalezparejasi gen. et sp. nov. from the Upper Cretaceous of Mendoza Province, Argentina. With a powerfully-constructed humerus 1.76 m in length, Notocolossus is one of the largest known dinosaurs. Furthermore, the complete pes of the new taxon exhibits a strikingly compact, homogeneous metatarsus—seemingly adapted for bearing extraordinary weight—and truncated unguals, morphologies that are otherwise unknown in Sauropoda. The pes underwent a near-progressive reduction in the number of phalanges along the line to derived titanosaurs, eventually resulting in the reduced hind foot of these sauropods.

    Full Text Available Increasing urban vegetation is known worldwide to be a strategy for mitigating urban heat islands. This study evaluates how the energy balance of an urban canyon is affected by different combinations of urban morphology, tree species features, and building density. The thermal behaviors of 16 urban canyons, 16, 20 and 30m in width, located in areas of high and low building density, with three predominant types of tree species in the city were monitored in summer, in addition to one tree-free case. The COMFA energy balance model was used to assess the degree of habitability of open spaces. The results show that the appropriate selection of tree species is the key to maximizing the energy efficiency and habitability of urban spaces in areas of low building density in the city.

    2015-01-01

    Full Text Available In early 1917, a company that gathered all of Mendoza’s wine producers was founded. This was the last anti-cyclical strategy promoted by the State with the goal of dealing with a long lasting economical crisis. It aimed to set wine and grape prices in a monopolistic fashion, and to establish wine marketing quotas. The limited amount of bibliography on this topic is what motivated this study, based on 3 aspects: how it was created, who it benefitted and how it was dissolved. Lack of official documentation forced its story to be rebuilt with information gathered from newspapers and public and private memoirs. It was concluded that the ideas this experiment was based on were misguided, since wine is a dispensable and replaceable asset. It was also concluded that it benefitted wine growers and that its dissolution process was longer and more complex than it foreseen.

En este contexto hubo una reproducción de situaciones conocidas. Pero también se procesaron cambios importantes. Uno de éstos estuvo relacionado con la irrupción de los liderazgos regionales, de naturaleza y envergadura diversa. Encontramos una puja muy particular entre el liderazgo de Venezuela en un proyecto alternativo y la respuesta geopolítica de Estados Unidos a través de Colombia. La realidad de los liderazgos impactó notoriamente a Argentina. Fue evidente que a partir de la crisis de 2001 perdió capacidad de influencia en la región.

    Full Text Available Aquí se presenta un detallado estado de las investigaciones arqueológicas desarrolladas en el noreste de la provincia argentina de Mendoza. Esta zona es objeto de estudios desde principios del siglo XX. Sin embargo los pulsos de la investigación han registrado etapas de abandono total y de intervenciones selectivas. Los investigadores han partido de los trabajos precedentes para explicar por extensión las modalidades de asentamiento en la totalidad del territorio norte y, sobre todo, del occidente montañoso, que era donde concentraban sus campañas. Esto acabó generando un cuadro de antecedentes desequilibrado y superficial en el conocimiento de dicha área, con implicaciones en el cuadro interpretativo general de la prehistoria local. En este caso, indagamos las posibles causas que dieron lugar a tal proceso, sus vínculos con los enfoques teóricos y metodologías dominantes a lo largo del siglo XX y su relación con la selección de zonas para llevar a cabo estudios de campo en el norte de la provincia. Reflexionamos críticamente sobre los alcances, límites y posibilidades que ofrece la región para profundizar los análisis arqueológicos del poblamiento prehispánico en relación con las condiciones del ambiente y los procesos históricos documentados, proponiendo discutir los enfoques que basan sus explicaciones en hechos dados por sentados y que merecerían antes una discusión en base a la evidencia disponible.

The entity created to handle the winemaking was Junta Reguladora de Vinos, which began operations after 1935. At the same time that they put into execution the provisions adopted by this national institution, the provincial authorities in the producing region arbitrated various practices designed to offset the sharper edges of the crisis and to reposition the agricultural industry at local and national market. In the province of Mendoza provincial authorities prescribed, starting in 1936, some regulations aimed at modernizing the state apparatus in an attempt to achieve greater efficiency in the implementation of regulatory policies and making the machinery of government to the demands of the new stage. The creation of a office specifically dedicated to the production of statistics and economic research under the provincial Ministry of Finance was the most important measure in this regard, while other provisions were trying to find in contemporary tourism development of a complementary alternative traditional winesLas políticas implementadas en el país para superar las consecuencias de la crisis de 1930 se manifestaron, en el caso de las actividades agrarias y agroindustriales, en medidas de regulación de la producción y el comercio.

    The El Corcovo lava flow, from the Huanul shield volcano in the southern Mendoza province (central-western Argentina) traveled a distance of 70 km and covered a minimum area of ~ 415 km2. The flow emplacement was controlled both by extrinsic (e.g., topography) and intrinsic (e.g., lava supply rate, lava physicochemical characteristics) factors. The distal portion of the lava flow reached the Colorado River Valley, in La Pampa Province, where it spread and then was confined by earlier river channels. Cross-sections through the flow surveyed at several localities show two vesicular layers surrounding a dense central section, where vesicles are absent or clustered in sheet-shaped and cylindrical-shaped structures. Lavas of the El Corcovo flow are alkaline basalts with low values of viscosity. The morphological and structural characteristics of the flow and the presence of landforms associated with lava accumulation are the evidence of inflation. This process involved the formation of a tabular sheet flow up to 4 m of thick with a large areal extent in the proximal sectors, while at terminal sectors frontal lobes reached inflation values up to 10 m. The numerous swelling structures present at these portions of the flow suggest the movement of lava in lava tubes. We propose that this aspect and the low viscosity of the lava allowed the flow travel to a great distance on a gentle slope relief.

    Four energy-efficient demonstration school buildings were built in the western province of Mendoza, Argentina, in 1999, as part of a massive building program required to implement the new Federal Education Plan. The buildings should make medium use of bioclimatic strategies and daylighting. The aspects of typology of the classroom tiers became immediately apparent as one of the main conditioners of the overall scheme. Three different alternative schemes were designed and built. A deeper analysis of these and other possible alternatives were thought essential for future constructions of the type. Four typologies of the classroom tier, using the same, locally available technology, are being comparatively assessed in the aspects of energy efficiently, thermal and luminous comfort, construction and operation costs and environmental impact (LCA). The paper presents the provisional results of the two first items only: energy efficiency and thermal comfort. While all four schemes evaluated are believed to be ''workable'', differences will tend to favour some the other according to context situations. Volumetric Loss Coeff. range from 1.09 to 1.24 W/Km{sup 3}. Solar savings fractions for the school operation hours vary between: 82.83 and 91.58%. Work is being continued to cover all the analysis items in a combined way. (author)

    Full Text Available En el presente artículo analizamos cómo funcionarios de la Municipalidad de Lavalle representan e interpelan a las comunidades indígenas huarpe situadas en el área no irrigada del noreste de Mendoza, área situada en el departamento de Lavalle. Éste se encuentra dividido socioterritorialmente en dos espacios. Uno irrigado, caracterizado como área de progreso, de producción agrícola y de herencia europea y el otro no irrigado, representado como área de atraso, de producción ganadera y de herencia precolonial. A partir de un análisis etnográfico, analizamos cómo el municipio gestiona local y cotidianamente la diversidad étnica, cultural, económica y política. Concluimos que las formas con que los funcionarios interpelan a las comunidades indígenas y a sus integrantes son en base a un doble movimiento, uno de reconocimiento explícito y el otro de individualización, invisibilización y deslegitimación hacia las mismas. Al invisibilizar a las comunidades como sujetos colectivos, funcionarios municipales intentan dar una identidad común que incorpore a los espacios irrigados y no irrigados y a sus poblaciones como pertenecientes a un mismo territorio, el departamental, a la vez que mantenga la jerarquización entre ambos. Al realizar este movimiento, el municipio se erige como el unificador y contenedor de ambos espacios y de los distintos grupos socio-étnicos que los integran.

La acumulación de unidades de frío Utah modificada (UFUM que presentan las zonas estudiadas, San Martín y Junín, varía a través de los años. En tales áreas el cultivo del cerezo aún no se ha difundido. Junín posee un valor medio de 884 UFUM, mientras que en San Martín es de 816 UFUM, suficiente sólo para variedades de requerimientos bajos. El 95% de los ciclos invernales oscilaron de 459 a 1310 para Junín y de 390 a 1241 UFUM para San Martín. En ambos departamentos sólo el 45% de los años se alcanzan las 900 UFUM, mientras que la probabilidad de cumplir 900 UFUM es 57% y 41% para Junín y San Martín respectivamente. La probabilidad de 1200 UFUM es de sólo 8 y 5% para Junín y San Martín respectivamente. Este estudio establece bases que deberían ser consideradas para el desarrollo de proyectos de producción de cerezas en áreas con baja disponibilidad de frío y sin experiencia en el cultivo. Además, permitiría seleccionar las variedades más adaptadas y desarrollar una zonificación para el cultivo.The lack of winter chilling has an effect on fruit quality and yield in stone fruits. Sweet cherry trees have strong winter chilling demands. The accumulation of modified Utah chill units (MUCU observed in these areas, San Martín and Junín, is variable. In these areas, the cultivation of the sweet cherry tree has not spread yet. Junín shows a mean of 884 MUCU, meanwhile San Martín has 816 MUCU, just enough for low requirement varieties. However, 95% of winters oscillated between 459 and 1310 MUCU for Junín, and 390 to 1241 MUCU for San Martín. In both areas only 45% of the years reaches 900 MUCU, while probabilities to fulfill 900 MUCU are 57% and 41% for Junín and San Martín respectively. The probability of 1200 MUCU is 8% and 5% for Junín and San Martín. This study establishes the basis that should be considered for sweet cherry development projects in areas with low chilling availability and no experience in crop production. Moreover, it allows to select more adapted varieties and to develop crop zoning.

    This view of northern Patagonia, near El Cain, Argentina shows complexly eroded volcanic terrain, with basalt mesas, sinkholes, landslide debris, playas, and relatively few integrated drainage channels. Surrounding this site (but also extending far to the east) is a broad plateau capped by basalt, the Meseta de Somuncura. Here, near the western edge of the plateau, erosion has broken through the basalt cap in a variety of ways. On the mesas, water-filled sinkholes (lower left) are most likely the result of the collapse of old lava tubes. Along the edges of the mesas (several locations) the basalt seems to be sliding away from the plateau in a series of slices. Water erosion by overland flow is also evident, particularly in canyons where vegetation blankets the drainage channels (green patterns, bottom of image). However, overland water flow does not extend very far at any location. This entire site drains to local playas, some of which are seen here (blue). While the water can reach the playas and then evaporate, what becomes of the eroded rock debris? Wind might excavate some of the finer eroded debris, but the fate of much of the missing bedrock remains mysterious.This cross-eyed stereoscopic image pair was generated using topographic data from the Shuttle Radar Topography Mission, combined with an enhanced Landsat 7 satellite color image. The topography data are used to create two differing perspectives of a single image, one perspective for each eye.

  12. The Barrancas anticline in west-central Argentina: new geomorphic and geologic constraints on the geometry and activity of a fault-related fold

    2016-12-01

    The Barrancas anticline in Mendoza Province, west-central Argentina is a N-NW-oriented, east-vergent fault-bend fold located in the transition from the mainly east-vergent, thin-skinned Argentine Precordillera to the mainly west-vergent, thick-skinned Sierras Pampeanas — one of the most active thrust zones on Earth. Previous studies of the Barrancas anticline interpreted its structure from 2-D and 3-D seismic data. The anticline is a fault-bend fold with multiple segments with different uplift histories and which linked only after 2.3Ma. This study aims to establish the temporal persistence of segmentation and to describe the role, extent and rates of deformation processes involved in the development of the Barrancas anticline from morphometric analyses, geologic and geomorphic mapping, and accurate dating of relevant geomorphic features. Longitudinal profile analysis of streams on the anticline reveals marked differences in normalized steepness index (ksn) between the western and eastern limbs as well as variation along strike. This distribution of ksn values reveals patterns consistent with asymmetry and segmentation of the Barrancas anticline. Swath profiles parallel to the fold axis resemble fault slip distribution profiles which was a basis for segmentation from previous studies. Drainage basin morphometric indices such as hypsometry, drainage density, and basin elongation were also measured. Hypsometric integral values were particularly higher on the west than on the east, possibly indicating younger folding on the western limb. This study will contribute to a better understanding of the nature, extent, timing, and rate of folding at the transition from thin- to thick-skinned thrust deformation in west-central Argentina. Additionally, this study will contribute to assessment of seismic hazards associated with fault-related folds in Argentina and in similar tectonic settings worldwide.

This contribution shows the main characteristics of the talc mineralization related to the Río de Las Tunas ultramafic bodies in the Salamanca Mining District, Frontal Cordillera of Mendoza province. According to the parageneses defined on the studied samples, three generations of talc were established: 1º crystallized in metaperidotites and related to the prograde stage of the regional metamorphism; 2º crystallized inreaction zones (mostly in the talc zone developed at the boundary between metaperidotites and their country-rocks.These reaction zones evidence a metasomatic process due to geochemical gradient between the ultramafic body and their country-rocks. This process was developed during the retrogression of the regional metamorphic cycle. 3º Talc present in shear-zones that cut across the ultramafic bodies. The extreme serpentinization of the ultramaficbodies is concentrated in shear-zones where the serpentine is subsequently replaced by talc ± carbonates related with a hydrothermal stage. Aqueous fluids relatively enriched in CO2 flowed through these shear-zones causing the cease of serpentine formation favoring the talc and/or carbonates. Mined talc deposits are those in shear zones and reaction zones. They are mostly industrial-, asbestine- or talcschist-type. The talc related to the hydrothermal stage can locally reach first and extra qualities.

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

  5. Measuring turbidity, and indicator to evaluate drinkability of waters in Southern countries? Approaches from Burkina Faso, Sudan and Argentina case studies

    2013-04-01

    The relationship between proportion of suspended solids, dissolved oxygen and bacteriology has long been proven (Brock, 1966; Lechevallier et al., 1985; Bustina and Levallois, 2003; Chang and Liao, 2012), bacteria need coarse elements to hang on and develop. However, water bacteriology analyses are difficult to implement in southern countries. They are expensive and require sterile equipment, transport in cold conditions and a nearby laboratory, which remains difficult in remote areas under these hot latitudes. Yet, simple measurement devices allow to know in a few minutes the water turbidity. Is turbidity an efficient tool to evaluate the drinkability of water when no bacteriological analyses are possible? The results proposed here are taken from three different studies whose purposes were to measure different physical, chemical and bacteriological parameters of water used for human and/or animal consumption. One of the finalities was to propose a method, at lower cost, to evaluate the drinkability of water for consumption. Four case studies were chosen: the basin of the Doubegue River in Burkina Faso is a rural area of a developing country, where drinking water is taken from the alluvial aquifer close to the surface. Furthermore, the laundry is washed and the children play in running streams. Major expansion of the cultivated lands since 1980s has brought important soils losses, thus a chronicle contamination of surface water with suspended solids (Robert, 2012). The Mendoza and Tunuyán Rivers Basins in Argentina, an emerging country, have snow-glaciar regimes with naturally turbid waters. They supply drinking water to two towns, Mendoza and Tunuyán cities, respectively 1 million and 40,000 inhabitants. However, these two streams -whose watersheds are common- do not present the same managements: the Mendoza River has been equipped with large hydraulic infrastructures, moving the turbid waters into clear and erosive ones (Lavie, 2009), while the Tunuyán River

    Full Text Available En Mendoza las aguas subterráneas son un recurso natural indispensable para la subsistencia y de gran importancia para el desarrollo provincial, ya que tienen un valor no solo económico y estratégico, sino también social y ambiental. La prevención de la sobreexplotación de los acuíferos y de la contaminación de estas aguas constituye una de las preocupaciones más serias a la que se enfrentan los encargados de gestionar su uso eficiente. Para ello resulta necesario aplicar políticas de ahorro y conservación, contar con un moderno Derecho de aguas preciso, claro, coherente y conservacionista, encaminado a dar soluciones eficaces a los problemas que hoy se nos presentan y que la gestión se realice con rectitud, transparencia y respetando la Constitución y la leyes.

    Gouiric-Cavalli, Soledad; Cione, Alberto Luis

    2015-11-01

    The marine deposits of the Vaca Muerta Formation (Tithonian-Berriasian) houses one of the most diverse Late Jurassic ichthyofaunas of Gondwana. However, most of the specimens remain undescribed. Jurassic fishes have been recovered from several localities at Neuquén Province (i.e., Picún Leufú, Plaza Huincul, Cerro Lotena, Portada Las Lajas, Los Catutos, and Arroyo Covunco) but also from Mendoza Province (i.e., La Valenciana, Los Molles, and Arroyo del Cajón Grande). Presently, the fish fauna of Los Catutos, near Zapala city (Neuquén Province), has yielded the highest number of specimens, which are taxonomically and morphologically diverse. At Los Catutos locality, the Vaca Muerta Formation is represented by the Los Catutos Member, which is considered the only lithographic limestones known in the Southern Hemisphere. Here, we review the Tithonian fish faunas from the Vaca Muerta Formation. During Late Jurassic times, the actual Argentinian territory could have been a morphological diversification center, at least for some actinopterygian groups. The apparently lower species diversity recorded in marine Jurassic ichthyofaunas of Argentina (and some Gondwanan countries) in comparison with Chilean and European fish faunas could be related to the fish paleontological research history in Gondwana and the low number of detailed studies of most of specimens recorded.

    Due to the low spatial and temporal resolution of the available measurements, highly variable air concentrations of several POPs have been observed in Latin American and Caribbean countries. This paper presents a high resolution spatially disaggregated atmospheric emission inventory for selected POPs in order to assess the environmental fate of some of these compounds in a finer resolution. As study case we estimated releases to air of POPs in a typical mid-size urban conglomeration in Argentina. Inventoried compounds were total polychlorinated biphenyls (PCBs, total polybrominated diphenyl ethers (PBDEs, total dichlorodiphenyltrichloroethane (DDT on a sum basis, hexachlorobenzene (HCB and dioxins and furans (PCDD/Fs, for which emissions were estimated in 0.92 kg/year, 1.65 kg/year, 4.2E−02 kg/year (total sum of congeners, 0.86 kg/year and 4.4E−02 kg/year respectively, values that are in accordance with the geographic and economic context. Although emitting sources are quite varied, there are very clear trends, particularly in relation to open burning of municipal solid waste and agrochemical use as major contributors. Overall, the inventory provides valuable data for the analysis of the heterogeneity of POP emissions and the necessary inputs for air quality modeling.

    Mendoza is a province of Argentina located between 32° S and 34° S at the leeside of the Andes Foothills. Very intense thunderstorms form between October and March (southern hemisphere summer), which produce large hail and damage in crops and properties. Although some hypotheses and conceptual models were proposed in order to identify key possible mechanisms that contribute to trigger convection, they are still waiting for the validation process. As moisture is the main ingredient for storms formation, the identification of its geographical distribution could be used together with other synoptic and mesoscale forcing features to forecast intense convective events. A novel technique in estimating moisture concentration and its geographical distribution has been introduced in order to observe the influx and variability of humidity at this region, during a 45-day period in midsummer. In doing so, we resort to the information provided by the ground-basedGlobal Navigation Satellite System (GNSS) network. More than 300 active stations constitute the continuously operating GNSS network over Southern and Central America (SIRGAS-CON, Sistema de Referencia Geocéntrico para las Américas de Operación Continua). This network allows to retrieve integrated water vapor (IWV) content, mapping this variable by the use of a digital model of terrain. In the period and region under study, a prevailing influx of humidity from N and NE and a high correlation between the accumulation/depletion of humidity and the hail/no hail precipitation days is observed. We discuss in particular the development of five storms detected by the S-Band radar network belonging to the Province of Mendoza. Although the results strongly suggest that IWV maps are capable to represent the humidity dynamics in the considered region, it is still important to highlight that the calculated values for IWV are unrealistic at some locations as the consequence of deep atmospheric gradients. These biases may be

    2017-01-01

    Full Text Available Este artículo evidencia las dificultades metodológicas y teóricas en el uso de indicadores sociales para evaluar la vulnerabilidad al cambio climático y de esta forma contribuye a refinar las estrategias metodológicas para el abordaje de este fenómeno. La mayoría de los estudios de vulnerabilidad al cambio climático la definen como una expresión de tres dimensiones: la exposición de los sistemas a los fenómenos climáticos, la sensibilidad a esas condiciones riesgosas, y su capacidad para afrontar los impactos que los afectan. Estas tres dimensiones facilitan la operacionalización del concepto a partir de indicadores biofísicos y sociales cuya principal finalidad es cuantificar el fenómeno y establecer relaciones de causalidad entre eventos y recursos. Frente a esta conceptualización, otra manera de entender el fenónemo es definirla como un proceso dinámico determinado procesos sociales, económicos, políticos, culturales e institucionales. Desde este enfoque el cambio climático impacta sobre una serie de vulnerabilidades previas y de largo plazo definidas principalmente por el acceso a los recursos. La vulnerabilidad se define entonces, como un proceso cuya complejidad no admite cuantificaciones ni generalizaciones entre causas y efectos como las que proponen los sistemas de indicadores. A partir de una experiencia de investigación concreta en las cuencas de los ríos Mendoza, en Argentina, y Chinchiná, en Colombia este artículo demuestra las limitaciones que el uso de indicadores de vulnerabilidad social conllevan para la investigación social aplicada. Con base en el análisis de datos estadísticos de uso público disponible en Argentina y en Colombia y de entrevistas en profundidad en las areas de estudio, los autores reconstruyen las dificultades enfrentadas al momento de construir dichos indicadores para demostrar las debilidades de cada indicador para dar cuenta del complejo fenómeno de la vulnerabilidad.

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

    Full Text Available La producción de vid es la fuente económica agroindustrial principal en Cuyo (28°S-36°S / 65°W-70°W, siendo la región de más elevado desarrollo vitivinícola del país. Uno de los factores climáticos de mayor impacto en la producción de vid es la destrucción del cultivo por granizo, como resultado de la convección severa desarrollada en época estival. La violencia con que se desarrollan las tormentas estivales de granizo genera un impacto importante en el rendimiento de los viñedos afectados, logrando la disminución parcial o total de parcelas enteras. Durante el período 1979-2008, la precipitación de verano presenta fluctuaciones de la escala 7-8 años al igual que la producción total de vid y ambas se encuentran inversamente correlacionadas intradecádicamente. Asimismo, veranos húmedos (secos pueden presentar mayor (menor probabilidad de ocurrencia de daños por granizo en la temporada actual que se pueden asociar a menor (mayor producción de vid en la temporada del año siguiente debido a cambios en la disponibilidad de yemas fértiles.

En este trabajo pretendemos relevar a propósito de la celebración del sesquicentenario de Mayo la producción historiográfica mendocina que circuló en espacios de divulgación, constituyéndose en una fuerte tradición que perduró en los espacios académicos locales. Más allá de explicar la incidencia que tuvieron en la refracción de otras corrientes de pensamiento, las tesis interpretativas que ven a Mayo como un momento de reafirmación de la hispanidad y que niegan su sentido emancipatorio, así como los recorridos biográficos de sus autores, revelan redes de sociabilidad intelectual que bajo la nominación de nacionalismo encubrían no pocas especificidades, al mismo tiempo que revelaban las vinculaciones existentes con la escuela historiográfica sevillana, por entonces usina intelectual del franquismo y nutriente del pensamiento nacionalista conservador y autoritario de los años sesenta.Research on the nationalism present in post- Peronism in Mendoza has allowed us to retrieve a number of intellectual itineraries that exemplify the complexity of a period in which the circulation and traffi c of ideas show not only strong identity mutation processes, but also the crystallization of undoubtedly anachronistic positions.

    Full Text Available A través de un estudio etnográfico en la periferia del oasis de riego más importante del centro-oeste argentino, se analiza la intervención de persistentes representaciones étnico-raciales y ambientales en la delimitación de áreas irrigadas y de grupos sociales que ostentan la tenencia del agua y la tierra. Los grupos situados a uno y otro lado de los últimos canales de riego son interpelados desde paradigmas modernistas que vinculan a la tenencia del agua, la propiedad privada y la producción vitivinícola con la herencia europea y la idea de progreso, mientras que lo no irrigado, la tenencia comunitaria de la tierra y el pastoreo trashumante se asocia a la descendencia indígena huarpe y a la idea de atraso o involución. Debido a la presencia de dos espacios y grupos socio-culturales supuestamente autónomos, opuestos y separados por los últimos canales de riego es que se los conceptualiza como frontera hídrica. Esta, a pesar de ser considerada como natural y fija, es por el contrario artificial y dinámica, producto de luchas sociales y simbólicas por el agua y por la obtención de legitimidad como grupo socio-cultural capaz de obtenerla y controlarla. Asimismo se resaltan la presencia no solo de actores liminales, ni huarpes ni de origen europeo, sino también de alianzas que pueden llevar a la reconfiguración de espacios irrigados y de grupos socioculturales capaces de dar batalla en las disputas por los recursos naturales.

    Full Text Available El descubrimiento de la enfermedad como problema social fue parte de la “ideología urbana” articulada en torno del progreso, el orden, la higiene y el bienestar, a partir de la segunda mitad del siglo XIX. Los males comenzaron a atraer la atención de los dirigentes y es ahí donde la higiene (urbana y humana empieza a tomar importancia como instrumento de intervención preventivo y a la vez disciplinador, convirtiéndose en parte del progreso y la civilización. La práctica higienista y los imaginarios en torno de ella, redujeron los problemas urbanos a los meramente sanitarios y morales hasta las primeras décadas del siglo XX. Ese fue el caso de Mendoza y su “Barrio de las Ruinas”. La ciudad colonial convertida en periferia tras el terremoto de 1861, permaneció llena de escombros hasta iniciada la década del ’80. Es la visión higienista finisecular, la que modifica la actitud del gobierno, que comenzó a ver el peligro que era tener una zona degradada cerca de la Ciudad Nueva. En esa línea de acción está Luis Lagomaggiore. Intentaremos en este trabajo relacionar las acciones de gobierno con las imágenes en torno de la higiene. En este caso, la higiene del “otro”: el habitante de los suburbios representado en el Barrio de las Ruinas.

    Full Text Available Numerosos estudios han asociado los ámbitos urbano y rural a diferencias en el crecimiento y el estado físico. En la literatura, es frecuente vincular a la residencia urbana con un mejor crecimiento que la rural. El objetivo del estudio fue analizar la correspondencia entre área de residencia (urbana, periurbana y rural y estado nutricional. La muestra se constituyó con 1682 escolares que asisten a escuelas públicas del Departamento de General Alvear, Mendoza. Se relevaron peso corporal, estatura, estatura sentado, perímetro braquial y pliegues subcutáneos tricipital y subescapular y se calcularon los índices de masa corporal y córmico. Los datos fueron comparados con las referencias de NCHS. La composición y proporciones corporales fueron evaluadas empleando NHANES I y II. Se observó que el 7.4% de los niños tuvo bajo peso para la edad, 5.9% baja estatura para la edad y 5.8% bajo peso para la estatura. Las mayores prevalencias de desnutrición crónica correspondieron a las escuelas rurales, mientras que la desnutrición aguda no se asoció a un ámbito en particular. El análisis de sobrepeso y obesidad indicó prevalencias de 8.5% y 5.2% respectivamente, siendo mayor en las escuelas rurales y periurbanas. Los resultados obtenidos permiten inferir una relativa dependencia entre estado nutricional y área de residencia que resulta de un impacto diferencial del ambiente sobre los distintos sectores socioeconómicos de la población.

  18. Anaglyph: Basalt Cliffs, Patagonia, Argentina

    Science.gov (United States)

    2000-01-01

    Basalt cliffs along the northwest edge of the Meseta de Somuncura plateau near Sierra Colorada, Argentina show an unusual and striking pattern of erosion. Stereoscopic observation helps to clarify the landform changing processes active here. Many of the cliffs appear to be rock staircases that have the same color as the plateau's basaltic cap rock. Are these the edges of lower layers in the basalt or are they a train of slivers that are breaking off from, then sliding downslope and away from, the cap rock. They appear to be the latter. Close inspection shows that each stair step is too laterally irregular to be a continuous sheet of bedrock like the cap rock. Also, the steps are not flat but instead are little ridges, as one might expect from broken, tilted, and sliding slices of the cap rock. Stream erosion has cut some gullies into the cliffs and vegetation (appears bright in this infrared image) shows that water springs from and flows down some channels, but land sliding is clearly a major agent of erosion here.This anaglyph was generated by first draping a Landsat Thematic Mapper image over a topographic map from the Shuttle Radar Topography Mission, then producing the two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and the right eye with a blue filter.Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972. SRTM topographic data match the 30-meter (99-foot) spatial resolution of most Landsat images and provide a valuable complement for studying the historic and growing Landsat data archive.

    2015-01-01

    Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in hydroxymethylbilane synthase (HMBS) produces a hepatic disorder named Acute Intermittent Porphyria (AIP); the acute porphyria is more frequent in Argentina. In this paper we review the results obtained for 101 Argentinean AIP families and 6 AIP families from foreign neighbour countries studied at molecular level at Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP). Thirty-five different mutations were found, of which 14 were described for the first time in our population. The most prevalent type of mutations was the missense mutations (43%) followed by splice defects (26%) and small deletions (20%). An odd case of a double heterozygous presentation of AIP in a foreign family from Paraguay is discussed. Moreover, it can be noted that 38 new families were found carrying the most frequent mutation in Argentina (p.G111R), increasing to 55.66% the prevalence of this genetic change in our population and adding further support to our previous hypothesis of a founder effect for this mutation in Argentina. Identification of patients with an overt AIP is important because treatment depends on an accurate diagnosis, but more critical is the identification of asymptomatic relatives to avoid acute attacks which may progress to death.

    Full Text Available La huella de Galicia en nuestro imaginario fundador no es proporcional a su gran importancia demográfica. A tal punto que, como sucede con los pueblos aborígenes, la identidad gallega suele ser en la Argentina una “criptoidentidad”, profunda y poco visible en muchos sentidos. Este trabajo propone varias razones posibles para este olvido u ocultamiento deliberado: la carga insultante que el gentilicio “gallego” (luego equivalente aquí a “español” en general traía desde la Península, el peso de algunos rasgos despectivos de este estereotipo étnico, el rechazo de España como matriz cultural que se prolongó después de la Independencia; el rápido abandono de la lengua gallega por el deseo de asimilarse al más prestigioso castellano. Cuando comiencen las reivindicaciones hispanistas por parte de intelectuales argentinos, la mayor parte no incluirá a Galicia. Y, aunque la prensa de las asociaciones y las élites de artistas y escritores gallegos intenta revertir esta tendencia, no logra incidir lo suficiente en la sociedad argentina, ni dentro del mismo colectivo migratorio. Pero hoy día, movimientos galleguistas en las nuevas generaciones avanzan hacia el reconocimiento de la identidad gallega como uno de los pilares ocultos de la identidad argentina, y viceversa, en lo que hace al aporte argentino a la comunidad gallega peninsular.

    Full Text Available El exceso de peso representa un problema emergente en salud pública, su prevalencia varía según zona de residencia, nivel socio-económico, edad y sexo. El objetivo del trabajo fue analizar las prevalencias de sobrepeso y obesidad en niños urbanos y rurales del Departamento de San Rafael, Mendoza, en relación a las condiciones socio-ambientales. Se realizó un estudio antropométrico transversal en 1176 individuos de 6 a 12 años. Se relevaron peso corporal, talla y pliegues subcutáneos tricipital y subescapular. El sobrepeso y la obesidad fueron determinados utilizando los criterios del International Obesity Task Force. El patrón de distribución adiposa se analizó mediante el índice Subescapular/Tricipital (IST. Un valor de IST>1 indicó centralización adiposa. El relevamiento socio-ambiental se realizó mediante encuesta autoadministrada. Los datos fueron procesados por análisis de componentes principales categórico (catACP. El catACP discriminó cuatro grupos según su condición socio-ambiental: Urbano: (Alto, Medio y Empobrecido y Rural. Las prevalencias para sobrepeso fueron de 14,4% y para obesidad de 7,6%, siendo las diferencias sexuales no significativas. La población con sobrepeso presentó en ambos sexos, valores de IST<1. En los varones obesos el IST fue >1 a partir de los 9 años y en las mujeres a los 9 y 12 años. El sobrepeso se distribuyó homogéneamente en los cuatro grupos, en tanto que la obesidad fue mayor en el grupo con características rurales. Los resultados dan cuenta del creciente aumento del sobrepeso con distribución homogénea e independiente de la condición socioeconómica. La obesidad en cambio, se concentra principalmente en la zona rural.

  10. The eco-epidemiology of Triatoma infestans in the temperate Monte Desert ecoregion of mid-western Argentina

    Full Text Available BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of Lavalle Department in the Mendoza province. METHODS Technical personnel inspected 198 houses for evidence of infestation with T. infestans, and the 76 houses included in the current study were re-inspected. In parallel with the vector survey, an environmental and socio-demographic survey was also conducted. Univariate risk factor analysis for domiciliary infestation was carried out using Firth penalised logistic regression. We fitted generalised linear models for house infestation and bug abundance. Blood meals were tested with a direct ELISA assay, and T. cruzi infection was determined using a hot-start polymerase chain reaction (PCR targeting the kinetoplast minicircle (kDNA-PCR. FINDINGS The households studied included an aged population living in precarious houses whose main economic activities included goat husbandry. T. infestans was found in 21.2% of 198 houses and in 55.3% of the 76 re-inspected houses. Peridomestic habitats exhibited higher infestation rates and bug abundances than did domiciles, and goat corrals showed high levels of infestation. The main host-feeding sources were goats. Vector infection was present in 10.2% of domiciles and 3.2% of peridomiciles. Generalised linear models showed that peridomestic infestation was positively and significantly associated with the presence of mud walls and the abundance of chickens and goats, and bug abundance increased with the number of all hosts except rabbits.

Evaluamos la Varianza Molecular (AMOVA y determinamos la distancia genética mediante Fst, entre las poblaciones muestreadas. Los resultados emergentes del análisis de marcadores autosómicos indican que las distancias genéticas no presentan diferencias significativas entre la mayoría de las poblaciones analizadas, siendo Salta la única que difiere significativamente con respecto a las demás provincias (Fst: 0.00484-0.01601, p: 0.0498-0.0000. A partir de los resultados de Y-STRs determinamos una Diversidad Haplotípica de 0.9967, que exhibe además una notable homogeneidad en la distribución haplotípica determinada por AMOVA, no obstante, cierto grado de subestructura genética pudo ser detectada en la región Norte, en particular en la provincia de Salta, coincidiendo con los resultados de autosómicos. El análisis de distancia genética permite establecer tres grupos uno de los cuales incluye a la población de Salta junto con los grupos amerindios analizados. Los resultados obtenidos resaltan el interés de las poblaciones del NOA en las que se destaca el componente autóctono de nuestra población.

    Prieto, Mónica; Martínez, Claudia; Aguerre, Lorena; Rocca, María Florencia; Cipolla, Lucía; Callejo, Raquel

    2016-02-01

    Listeria monocytogenes is the causative agent of listeriosis, a food-borne disease that mainly affects pregnant women, the elderly, and immunocompromised patients. The primary treatment of choice of listeriosis is the combination of ampicillin or penicillin G, with an aminoglycoside, classically gentamicin. The second-choice therapy for patients allergic to β-lactams is the combination of trimethoprim with a sulfonamide (such as co-trimoxazole). The aim of this study was to analyze the antimicrobial susceptibility profile of strains isolated from human infections and food during the last two decades in Argentina. The minimal inhibitory concentration (MIC) of 8 antimicrobial agents was determined for a set of 250 strains of L. monocytogenes isolated in Argentina during the period 1992-2012. Food-borne and human isolates were included in this study. The antibiotics tested were ampicillin, chloramphenicol, trimethoprim-sulfamethoxazole, erythromycin, gentamicin, penicillin G, tetracycline and rifampicin. Breakpoints for penicillin G, ampicillin and trimethoprim-sulfamethoxazole were those given in the CLSI for L. monocytogenes. CLSI criteria for staphylococci were applied to the other antimicrobial agents tested. Strains were serotyped by PCR, and confirmed by an agglutination method. Strains recovered from human listeriosis patients showed a prevalence of serotype 4b (71%), with the remaining 29% corresponding to serotype 1/2b. Serotypes among food isolates were distributed as 62% serotype 1/2b and 38% serotype 4b. All antimicrobial agents showed good activity. The strains of L. monocytogenes isolated in Argentina over a period of 20 years remain susceptible to antimicrobial agents, and that susceptibility pattern has not changed during this period.

    Background/aim Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. Methods We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. Results The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as “progressives”, “Jurassics” or “conservatives” and “crudos” or “spoiled brats”. BAT marketed Lucky Strike to the “progressives” using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with “nationalistic values” in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. Conclusions The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions. PMID:18299308

  17. Neoliberalism and political actors in contemporary Argentina

    Directory of Open Access Journals (Sweden)

    Juan Manuel Reynares

    2017-11-01

    Full Text Available In this paper we set out a critical reading of the literature on political neoliberal actors in Argentina. We consider that the concentration of these studies in the national level has to do with a definition of neoliberalism as a set of economical and structural macro politics. We propose to define neoliberalism as a technology of government that intends to hegemonize an “enterprise form” in different social spheres, articulating a symbolical framework in a contingent and contentious way. This insight allows analyzing neoliberal identification processes as heterogeneous trajectories with diverse geographic and temporal scopes.

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

    Studies regarding stigma towards mental illness in Argentina blossomed after the first National Mental Health Law was passed in 2010. Methodological limitations and contradictory results regarding community perceptions of stigma hinder comparisons across domestic and international contexts but some lessons may still be gleaned. We examine this research and derive recommendations for future research and actions to reduce stigma. These include tackling culture-specific aspects of stigma, increasing education of the general population, making more community-based services available and exposing mental health professionals to people with mental illness who are on community paths to recovery.

    Full Text Available Buffalo’s production represents an important option as input source in livestock systems located in areas with little profitability by cattle. In mostly farms, cattle and buffalos are breeding together, due that in Argentina, to carry out buffalo’s production is in an extensive way, with the aim to produce meat – mostly- milk – for this production nutritional supplements are used- and leathers. Brucellosis is zoonic illnesses from bacteria belong to Brucella which caused human human health problems by contaminated food ingestion or to those who are in touch with cattle. In Argentina, exist the National Control an Elimination Program for cattle Brucellosis, which include buffalos also, there is inclosed female vaccination and serologic segregation of positive reactants. Diagnosis techniques ruled for cattle brucellosis are BPA (Buffered Plate Agglutination, Tube seroaglutination and 2MercaptoEthanol. International reference test is Complement Fixation. By means of this present work, we pretend to evaluate the serologic diagnosis utility, ruled to the buffalos and compare obtained results by BPA, SAT and 2ME with Complement Fixation Test. In the present communication are presented results from the use of diagnosis techniques recommended by SENASA (National Service of Sanity and Quality Agro-Food to buffalo’s serums which belong to nine farms from NE Corrientes State. Obtained results show that association o BPA as Screening Test and SAT and 2ME as Confirmated Test has a valid correlation for the detection of positive animals with the reference technique Complement Fixation.

    Full Text Available In this paper we present reports of Yugoslav teachers who held classes to immigrants in Argentina 1939-1944, organized by the government of Kingdom of Yugoslavia. Teachers’ reports to Yugoslav Embassy in Buenos Aires testify of Kingdom of Yugoslavia efforts to oppose assimilation and promote and strengthen “Yugoslav national unity”. The reports also describe general social circumstances of Yugoslav immigrants, show various details from their everyday life and contain valuable data on numerous political, economic, social and cultural problems of this diaspora in Argentina and their relationship with motherland. We believe that archive materials presented in this paper opens numerous questions which could be topics of separate researches. Some of them could be the following: To which extent the teachers’ reports represented the actual situation and to which they were shaped to match policy and expectations of Kingdom of Yugoslavia? What was the actual influence of teachers to spreading the “national unity” among immigrants? Have their work left trace in Yugoslav diaspora and in which way? Beside all of the open issues, it is certain that teachers’ reports contain valuable data on immigrants’ everyday life, curriculum, schooling conditions, relationship with motherland, etc. [Projekat Ministarstva nauke Republike Srbije, br. 47016: Interdisciplinarno istraživanje kulturnog i jezičkog nasleđa Srbije.

    Orellano, Pablo W; Salomón, Oscar D

    2016-01-01

    Dengue outbreaks have occurred yearly in Argentina since 1998. A number of candidate vaccines have been tested in endemic countries. The most advanced one was licensed in three countries of Latin America for children over 9 years of age. In the present article the benefits and drawbacks of these vaccines as well as the challenges for the implementation of a vaccination strategy in Argentina are discussed. Furthermore, a risk stratification strategy with new criteria and a multidisciplinary vision is suggested as a possible path for the assessment of the pertinence of a vaccination program in areas showing the highest risk of dengue transmission and/or for people at the greatest risk of developing severe dengue. It is also suggested that the definition regarding the status of endemicity should take into account the local realities. Finally, this paper proposes a broad discussion on the evidences, the expected impact and instrumental aspects that would be involved in the incorporation of a dengue vaccine, marketed or in development, into the national immunization program, and especially which subpopulation should be targeted for the immunization strategy to be cost-effective.

    Records from forensic expertises and trappings with beef baits conducted in Buenos Aires, Argentina (34 degrees 36'S), show that the dominating species are widespread ones (Calliphora vicina and Phaenicia sericata), with different behaviour in each large latitudinal zone. It is suggested that the range of the yearly photoperiod variation has an influence in the behaviour of the blowflies, making up for differences in the succession patterns. The Calliphorid blowflies Cochliomyia macellaria and Chysomya albiceps were found on indoors corpses; the latter also on outdoors corpses when blood was shed, and in that case as primary. Three species of beetles of the genus Dermestes, which had been associated with mummified remains, appeared 10-30 days after death. The Silphid beetle Hyponecrodes sp. cf. erythrura was found on outdoor copses in rural environments. The Nitidulid beetle Carpophilus hemipterus was found in association with the cheese skipper Piophila sp. (Diptera: Piophilidae) in medullar cavities of bones after ca. 30 days; to this association is often added the Clerid Necrobia rufipes. Lepidoptera Tineidae appear on the head of mummified indoors corpses. North of parallel 32 degrees S, the Muscid grave-fly Ophyra sp. was found breeding on a corpse outdoors in summer. A division by latitude and climate is proposed for Argentina, and an extended system is proposed for the world.

    SLR technique is a proved astro-geodetic art with a significant power to contribute to Earth and Space Sciences. Therefore, scientific applications of SLR System are able to perform multiple tasks in the fields of Astrometry, Geodesy and Geophysics. The results we show here were obtained from satellite observations made at SLR 7406 Station of Observatorio Astronómico Félix Aguilar (OAFA) in San Juan, Argentina. The telescope was installed early on 2006, in concordance with an International Cooperation Agreement between Universidad Nacional de San Juan, Argentina and Chinese Academy of Sciences. In this abstract we show the current research being done with ILRS 7406 station: Length of day (LOD) and Angular velocity of Earth Rotation, calculated weekly; Pole Motion. ILRS7406 is daily surveying Pole coordinates x and y; Tracking SLR to GNSS constellations. SLR System contributes to the adjustment and validation of satellite GALILEO, GPS, GLONASS, and BEIDOU orbits. Our station is nowadays member of the new ITRF 2014 frame, and these past years has been one of the 3 highest producing SLR Stations on the ILRS net, composed of about 40 stations distributed all around the world. The obtained results during this first 10 years of experience are useful to enhance the traditional collaboration between OAFA and international services such as ILRS, IERS and NASA.

MATERIAL Y METODO: Entre 1986 y 1995 se implementaron Campañas de Información en los laboratorios de Análisis Clínicos de la región andinopatagónica argentina, destinadas a lograr una detección más eficiente de la difilobotriasis, a través de análisis coproparasitológicos. RESULTADOS: Adicionalmente, se confeccionaron planillas destinadas a recoger información sobre las características de la infección, del tratamiento y del paciente. Durante este período se detectaron 13 nuevos casos humanos, por identificación directa del parásito o por la presencia de huevos en materia fecal. Las características de las infecciones responden a las descriptas para el género Diphyllobothrium. CONCLUSIONES: En la región, los salmónidos son los peces predilectos en la pesca deportiva. Estos peces, frecuentemente parasitados con larvas, constituyen la principal fuente de contagio para el hombre al ser consumidos insuficientemente cocidos o ahumados en frío.

    In this paper, we identify 37 companies that produce nano-enabled products in Argentina. We locate the products of these firms in terms of both their economic sector and position in a value chain. The research was done through a four-step methodology. Firstly, an inventory of firms was created. Secondly, the firms were classified by their economic sector, following the United Nations economic classification. Thirdly, the firms were located within a simple nanotechnology value chain. Finally, the products were classified according to their final destination, being either means of production or final consumer products. The results show that healthcare, cosmetics, and medicine is the most represented sector along the value chain, followed by electronics.

The most promising changes for the fuel cycle economy is the Slight Enriched Uranium project which begun in Atucha I reactor. In 1997 seventy five fuel assemblies, equivalent to 900 Candu fuel bundles, will complete its irradiation. (author)

    Full Text Available El objetivo de este artículo es dar a conocer algunas hipótesis acerca de los modos como se construyen los relatos sobre las protestas populares en Argentina. Para ello expongo los resultados de una etapa de la investigación en la cual se han confrontado el análisis discursivo de textos de medios de comunicación dedicados a la protesta con un corpus de entrevistas a los protagonistas de estas acciones. Los resultados de dicha confrontación muestran la existencia de dos formas distintas de operar sobre el devenir histórico relacionadas no sólo con la distintiva puntuación temporal de la secuencia de los hechos, sino también con los procesos de enmarcado valorativo y su colocación en una serie histórica.

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

    Full Text Available While research on social ideas of nature focused on the discursive side of environmental rhetoric during the last decade of the twentieth century, the visual turn has introduced the analysis of its visual facet: the study of the visual representation of nature in photographs, films, paintings and media among many other image-based media. However, scarce attention has received the study of what is provoked by environmental images as well as how they shape our imagination and memory of environmental issues. Based on the analysis of mental maps created by 215 subjects -all of them students of the undergraduate programs of the Faculty of Humanities at Universidad Nacional del Centro de la Provincia de Buenos Aires Province (Argentina in 2013- as the starting point to identify images that have become constitutive environmental memory, the article discusses the role of environmental images in shaping both our ways of looking to nature and our understanding of environmental issues.

    Common vampire bat populations distributed from Mexico to Argentina are important rabies reservoir hosts in Latin America. The aim of this work was to analyse the population structure of the rabies virus (RABV) variants associated with vampire bats in the Americas and to study their phylodynamic pattern within Argentina. The phylogenetic analysis based on all available vampire bat-related N gene sequences showed both a geographical and a temporal structure. The two largest groups of RABV variants from Argentina were isolated from northwestern Argentina and from the central western zone of northeastern Argentina, corresponding to livestock areas with different climatic, topographic and biogeographical conditions, which determined their dissemination and evolutionary patterns. In addition, multiple introductions of the infection into Argentina, possibly from Brazil, were detected. The phylodynamic analysis suggests that RABV transmission dynamics is characterized by initial epizootic waves followed by local enzootic cycles with variable persistence. Anthropogenic interventions in the ecosystem should be assessed taking into account not only the environmental impact but also the potential risk of disease spreading through dissemination of current RABV lineages or the emergence of novel ones associated with vampire bats. © 2014 John Wiley & Sons Ltd.

    Argentina is a high-middle income country located in Southern South America with an estimated population of 44 million inhabitants. The epidemiological profile of the population is characterised by an increase of non-communicable diseases. The health system is heterogeneous, fragmented and loosely integrated. There are no unified research agenda or government initiatives encouraging the implementation of and research on shared decision making (SDM). Progress has been made lately to respect patient autonomy through the enactment of the 'Patients' Rights Act', which expressly enshrines the right of patients to get information as a key element of decision-making. To our knowledge, the team at the Department of Family and Community Medicine of the Hospital Italiano de Buenos Aires is the only one working on shared decision making in Argentina. This department carries out research, medical undergraduate and graduate training, and clinical practice implementation activities through strategies aimed at professionals and patients alike. We face some challenges regarding SDM, such as: 1) the fragmentation and the heterogeneity of the local health system; 2) we are a small group of people working on this topic who, simultaneously, have care, management, teaching and research responsibilities; 3) we have no government support and project funding is scarce; 4) due to the geographic location of the country, we must make a great effort in order to attend events on the state of the art in SDM. Given the current state of our health system, we believe the government is not likely to encourage, implement or research on SDM in the short term. Our group will continue to work on the local initiative and also to instil it in other interested groups. Copyright © 2017. Published by Elsevier GmbH.

    En Julio de 1997 se terminó con la primera parte de la instalación del ``Coronógrafo de Espejo para la Argentina'' en la estación de altura Carlos U. Cesco (El Leoncito), gracias al esfuerzo de la gente del Max Planck Institut für Aeronomie (Alemania), del OAFA y del IAFE. Dicho coronógrafo forma parte de un programa de ciencia bilateral entre Alemania y Argentina. El propósito del mismo, en conjunción con otros telescopios solares y terrestres, es contribuir a un mejor entendimiento de cuestiones fundamentales de la física solar. Para ello, ya está observando la corona de emisión en el verde (Fe XIV), rojo (Fe X) y Hα entre 1.05 y 2 radios solares aproximadamente. El diseño del instrumento, el cual fuera ya presentado en esta misma reunión en La Plata en 1996, es esencialmente similar al del telescopio LASCO-C1 a bordo del Solar Heliospheric Observatory (SOHO). La adquisición de datos se realiza con un CCD de 1280x1024 pixels, codificando en 12 bits, pudiendo ser el mismo operado en forma remota. En esta reunión presentaremos algunas de las observaciones realizadas durante la puesta a punto del instrumento en el período julio-setiembre de 1997. Asimismo expondremos cómo y por qué sus resultados complementarán a los de su par en el espacio.

    Full Text Available Luis Alejandro Gaite, Sebastián Marciano, Omar Andrés Galdame, Adrián Carlos GadanoHepatology Unit, Hospital Italiano de Buenos Aires, Buenos Aires, ArgentinaAbstract: Hepatitis C is the leading cause of chronic hepatitis, cirrhosis, and liver cancer in Argentina, where from 1.5% to 2.5% of adults are infected. Most of the infections were acquired 30–50 years ago. It is estimated that more than half of infected individuals are not aware of their infection. Even though the prevalence in blood donors has decreased to 0.45% at present, many high-prevalence populations still exist, where the reported prevalence ranges from 2.2% to 7.1%. Therapy is recommended for patients with fibrosis, in order to prevent disease progression, hepatic decompensation, and hepatocellular carcinoma. Great advances were achieved in the treatment of genotype 1 infection since the development and release of boceprevir and telaprevir. When either of these protease inhibitors is associated with peginterferon plus ribavirin, the sustained virological response (SVR rate improves from 40%–50% to 67%–75%. For genotype 2 and 3 infection, treatment with peginterferon plus ribavirin is still the standard of care, with SVR rates of 70%–90%. There are significant new antivirals in development, and some of them are close to being released. These drugs will most likely be the future standard of care for all genotypes, and will be incorporated in better-tolerated and highly effective all-oral regimes. The impact that these new therapies might have in health-related economics is unpredictable, especially in developing countries. Each country must carefully evaluate the local situation in order to implement proper screening and treatment programs. Difficult-to-treat patients, such as those with decompensated cirrhosis, patients in hemodialysis, and those with other significant comorbidities, might not be able to receive these new therapeutic approaches and their management

    2008-03-01

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

  5. Projected impact of a sodium consumption reduction initiative in Argentina: an analysis from the CVD policy model--Argentina.

    Konfino, Jonatan; Mekonnen, Tekeshe A; Coxson, Pamela G; Ferrante, Daniel; Bibbins-Domingo, Kirsten

    2013-01-01

    Cardiovascular disease (CVD) is the leading cause of death in adults in Argentina. Sodium reduction policies targeting processed foods were implemented in 2011 in Argentina, but the impact has not been evaluated. The aims of this study are to use Argentina-specific data on sodium excretion and project the impact of Argentina's sodium reduction policies under two scenarios - the 2-year intervention currently being undertaken or a more persistent 10 year sodium reduction strategy. We used Argentina-specific data on sodium excretion by sex and projected the impact of the current strategy on sodium consumption and blood pressure decrease. We assessed the projected impact of sodium reduction policies on CVD using the Cardiovascular Disease (CVD) Policy Model, adapted to Argentina, modeling two alternative policy scenarios over the next decade. Our study finds that the initiative to reduce sodium consumption currently in place in Argentina will have substantial impact on CVD over the next 10 years. Under the current proposed policy of 2-year sodium reduction, the mean sodium consumption is projected to decrease by 319-387 mg/day. This decrease is expected to translate into an absolute reduction of systolic blood pressure from 0.93 mmHg to 1.81 mmHg. This would avert about 19,000 all-cause mortality, 13,000 total myocardial infarctions, and 10,000 total strokes over the next decade. A more persistent sodium reduction strategy would yield even greater CVD benefits. The impact of the Argentinean initiative would be effective in substantially reducing mortality and morbidity from CVD. This paper provides evidence-based support to continue implementing strategies to reduce sodium consumption at a population level.

  6. Psychotherapy, psychoanalysis and urban poverty in Argentina.

    Epele, Maria Esther

    2016-12-01

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

    Full Text Available Argentina está creciendo fuertemente pero no logra trasladar similar tendencia a sus relaciones comerciales con el exterior. Su competitividad internacional, medida a partir de las capacidades de sus empresas para sostener o ganar mercados internacionales, no es similar a la de otros países del MERCOSUR y por el contrario pierde ventajas a medida que pasan los años. El proceso integrador del MERCOSUR no es causa de dicho debilitamiento sino que, por el contrario y como lo demuestra el desarrollo de otros países del bloque, puede ser un factor crítico para ayudar a mejorar la creación de comercio. Sin embargo, el bloque está sufriendo tensiones que le impiden crecer y consolidarse más y mejor a lo largo de los años. Esta situación afecta al país, ya que se le restan posibilidades de aprovechar dicha ventaja como lo supo hacer en las primeras etapas por medio del efecto de “desvío de comercio”. Los esfuerzos cotidianos de los hombres de negocios para hacer posible un MERCOSUR más fuerte y con menos tensiones, a partir de acciones continuas y permanentes, deben ser acompañados por acciones políticas en igual sentido y resolución pronta y justa de las tensiones internas

    The loss and transformation of habitat by anthropogenic activities is one of the main causes of biodiversity decrease. Amphibians are declining all over the world and one of the causes of this decline is thought to be habitat reduction. However, there are anuran populations in highly disturbed habitats, like cities. This study presents the ecological baseline needed to understand anuran communities in urban environments, for Salta City. Argentina (ca. 502,000 inhabitants). The sample was stratified by environments defined by infrastructure and geographic location. The species were identified by visual encounter techniques and by auditory transect during the 2002-2003 reproductive period. Three families, seven genera and twelve species were recorded and the species richness decreased from city border to center. Similarity index values among geographic areas was higher East-West (94.7) than South-West (33.3). Bufo arenarum was the only species recorded in all environments. Hyla andina and Odontophrynus americanus had a restricted distribution and are here considered vulnerable. The border effect can explain some distribution pattern in these populations. A map of the potential distribution of recorded species for Salta is provided.

  9. Triatoma infestans in Greater Buenos Aires, Argentina

    2001-05-01

    Full Text Available The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, potentially infested places were entomologically evaluated. T. infestans was only detected in a hen building for egg production, which housed approximately 6,000 birds. A total of 2,930 insects were collected. Density was about 9 triatomines/m². The proportions of fifth instar nymphs and adults were significantly higher than those of the other stages (p<0.001. The number of triatomines collected largely exceeded the highest domestic infestation found in one house from rural endemic areas of Argentina. Though triatomines were negative for Trypanosoma cruzi, they could acquire the parasite by coming in contact with infected people living in GBA. Besides, the numerous and widely distributed places housing hens and chickens, would favor the settlement of the vector. Together, both facts may constitute a risk of parasitic vectorial transmission. It is recommended to intensify systematic activities of vector search and case detection in GBA.

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

    Describing the development of PHC policy as promoted by Rosario Municipality (Argentina). A case-study was carried out during 2007 and 2008. Data was collected from secondary and primary sources (interviews, organisational census and observations). PHC development stages were identified by recognising the social norms which produced institutional change and transformation in municipal health services structure and health care and management models. The prevailing modes of governance in each stage were reconognised and characterised (clan, hierarchy and/or incentives). Four stages were identified between 1990 and 2008: 1990-1995/hierarchical mode: primary health care level organisation autonomied from hospitals. 1995-2000/ clan mode: developing of participatory managerial boards and community participation. 2000-2004/ clan mode: maturation of the "PHC movement" in competition with hospitals. 2004-2008/ clan-hierarchical mode: "movement's" crisis and constructions of norms tending towards enhancing an integrated network. Strengthening and empowering first-level health-care produced innovation favouring: the consolidation of a "PHC movement" having strong social commitment and improved services performance. The clan governance mode (regulating collective action via voluntary adhesion to shared values) was crucial for developing PHC between 1995 and 2004. Later on, the movement's fragmentation and the challenges of integrating the health system required developing hierarchical regulation mechanisms to complement the governance clan mode regulation.

    Full Text Available The development of alternative agricultural production can take different forms. In Argentina there is an important diversity of species available to be incorporated into production systems, giving support for the use of natural resources based on taking advantage of the regional fauna. Moreover the use of different animal species can be incorporated under the concept of the optimization of flows of energy and materials, tending to minimize the environmental impact of livestock production, and also to make more efficient use of the ingredients required for developing the activity. The integration of non-traditional species (minilivestock within the context of sustainable agricultural development was the motivation for the present study A module for raising Myocastor coypus (coypu or false nutha was developed, to which was linked a module for raising Eisenia foetida (the socalled red worm, in both cases with a dual purpose. Preliminary estimates were made of the productive aspects of both species, as well as an analysis of their integration, to understand the extent to which diversification linked with complementation tends to optimize the system.

    Full Text Available The blue land planarian Caenoplana coerulea is reported from Argentina (Buenos Aires province. We found C. coerulea in the east central region of Argentina in anthropic environments. The specimens that we found have the characteristic of the species found in others regions; that is, a bluish dorsal surface with a yellow mid-dorsal stripe and eyes forming a single row around the anterior tip, clustered laterally. This is the first record of this species from the Neotropical Region, and together with Bipalium kewense are the only 2 species of exotic terrestrial planarians so far recorded in Argentina.La planaria terrestre azul Caenoplana coerulea se registra para el centro este de Argentina (provincia de Buenos Aires, en ambientes antropizados.

    Full Text Available Psychology students are currently weakly organized in Argentina. The reasons for that maybe found in the circumstances of the local academic life and the changing social, economicand political realities the country went through in the last decades. In the meantime, thequality of the Psychology courses is poorer than its neighbouring Latinamerican countriesand it’s even more distanced from the world centres of academic reference. Nowadays,there are two developments encouraging the reflection and action of the students about that: the COBAND Project and the National Association of Psychology Students of Argentina (ANEPSI Argentina. Besides that, a magazine is published to endorse the creation of scientific reading habits among students. However, many challenges appear on the way to a Psychology more responsible to science and society.

    2016-06-01

    Full Text Available Since 20 years ago, a public-private alliance has transformed Argentina into a remarkable global actor in developing biotechnological products for food and renewable energies. This strategic alliance resulted in the boosting of scientific knowledge, the extension of the production boundary, the expansion of international trade and the creation of the conditions for an integral development. Furthermore, given the characteristics of biotechnology as a new phenomenon, wto has become the field within where a number of disputes take place, disputes which not only controvert trade issues, but also the State’s limits to design and apply public policies on the matter at issue. As a consequence, the present article seeks to, on the one hand, describe how Argentina built its public policy on Biotechnology and, on the other hand, analyze the challenges that Argentina faces within the multilateral trade system

  20. Neoliberalism in Argentina and Chile: common antecedents, divergent paths

    2015-09-01

    Full Text Available AbstractThis paper contrasts the experiences of neoliberalism in Argentina and Chile, exploring why two countries that implemented apparently similar market reforms came to different stances on marketization: a post-neoliberal politics in Argentina, and a tempered neoliberalism in Chile that has only recently come under scrutiny. The paper traces the common antecedents that inspired these reforms and the different outcomes and reactions that they produced. In contrast to recent literature, which emphasizes one or another explanatory factor, this article offers a synthetic comparison of the historical, political, economic, and ideological factors in play, helping to understand how capitalists achieved a hegemonic class position in Chile and not in Argentina.

    2012-07-01

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

Tendências econômicas e intelectuais perigosas, tais como a "globalização", o chamado Consenso de Washington, a dolarização e as negociações da Alca (Área de Livre Comércio das Américas, perderam ímpeto e a América do Sul está se movendo gradualmente na direção de um posicionamento mais independente na condução das suas política econômicas e internacionais. As mudanças foram muito mais significativas na Argentina do que no Brasil e isso se tornou fonte de alguma tensão entre os dois principais países sul-americanos. Não obstante, uma aliança estratégica entre Argentina e Brasil continua sendo a pedra angular da integração da América do Sul.THIS PAPER discusses some aspects of the recent economic evolution of Brazil, Argentina and other South American countries. Dangerous economic and intellectual trends, such as "globalization", the so-called Washington Consensus, dollarization, and FTAA (Free Trade Area of the Americas negotiations, have lost momentum and South America is moving gradually towards a more independent stance in the conduct of its economic and foreign policies. Changes have been much more significant in Argentina than in Brazil and this has become a source of some tension between the two major South American countries. Nevertheless, a strategic alliance between Argentina and Brazil remains the corner stone of South American integration.

    While Argentina has significantly improved access to HIV care and antiretroviral therapy (ART) for both the general population and prisoners, the prevalence of alcohol use disorders (AUDs) among HIV-infected prisoners and their relationship to accessing ART in Argentina is currently unknown. This study aims to characterize the substance abuse patterns of HIV-infected prisoners in Argentina and to assess the independent correlates of receipt of pre-incarceration ART. An anonymous, cross-sectional survey of 100 HIV-infected federal prisoners was conducted in the Buenos Aires municipality from July-December 2010. AUDs were assessed using the AUDIT scale. A majority (63 per cent) of participants met criteria for AUDs, 45 per cent of subjects were diagnosed with HIV in prison and one-quarter had initiated ART during the current incarceration. In addition, over one-third (35 per cent) of participants did not receive ART during the pre-incarceration period despite receiving it upon incarceration. This correlated significantly with the presence of having an AUD (AOR 0.20, 95 per cent CI 0.06-0.74, p = 0.016). AUDs are prevalent among HIV-infected prisoners in Argentina and are significantly related to negative secondary HIV prevention and treatment outcomes. While Argentina has provided an exemplary model of HIV-related health care reform within its prisons, future efforts to provide screening and treatment for AUDs are needed to improve the health of the nation’s incarcerated population. This paper is the first to describe pre-incarceration drug and alcohol use disorders and issues related to access to ART among prisoners in Argentina.

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

Trabajaremos en este caso, sobre la relación entre un conjunto de representaciones que el campo político despliega sobre el espacio urbano. Nos centraremos en analizar cómo la ciudad se transforma a partir de ocupaciones simbólicas del espacio urbano, en el escenario de la disputa política de dos agentes opositores dentro de ese campo en Mendoza: Emilio Civit y José Lencinas, entre 1910 y 1918 aproximadamente. Veremos cómo la ideología como una de las condicionantes de producción de representaciones sociales, incide y hace variar las relaciones entre espacio y sociedad.

  14. Projected Impact of a Sodium Consumption Reduction Initiative in Argentina: An Analysis from the CVD Policy Model – Argentina

    2013-01-01

    Background Cardiovascular disease (CVD) is the leading cause of death in adults in Argentina. Sodium reduction policies targeting processed foods were implemented in 2011 in Argentina, but the impact has not been evaluated. The aims of this study are to use Argentina-specific data on sodium excretion and project the impact of Argentina’s sodium reduction policies under two scenarios - the 2-year intervention currently being undertaken or a more persistent 10 year sodium reduction strategy. Methods We used Argentina-specific data on sodium excretion by sex and projected the impact of the current strategy on sodium consumption and blood pressure decrease. We assessed the projected impact of sodium reduction policies on CVD using the Cardiovascular Disease (CVD) Policy Model, adapted to Argentina, modeling two alternative policy scenarios over the next decade. Results Our study finds that the initiative to reduce sodium consumption currently in place in Argentina will have substantial impact on CVD over the next 10 years. Under the current proposed policy of 2-year sodium reduction, the mean sodium consumption is projected to decrease by 319–387 mg/day. This decrease is expected to translate into an absolute reduction of systolic blood pressure from 0.93 mmHg to 1.81 mmHg. This would avert about 19,000 all-cause mortality, 13,000 total myocardial infarctions, and 10,000 total strokes over the next decade. A more persistent sodium reduction strategy would yield even greater CVD benefits. Conclusion The impact of the Argentinean initiative would be effective in substantially reducing mortality and morbidity from CVD. This paper provides evidence-based support to continue implementing strategies to reduce sodium consumption at a population level. PMID:24040085

    Full Text Available Thermospheric and mesospheric structures are studied using an all-sky imager located at El Leoncito, Argentina (31.8° S, 69.3° W, –18° mag lat. This site has relatively high geographic latitude for a location under the crest of the equatorial ionization anomaly (EIA, and thus observations can be used to study the intrusion of several equatorial processes into the midlatitude domain. In addition, it has a conjugate point close to the field of view of our companion imager at Arecibo, PR, allowing for the study of inter-hemispheric effects. Four types of phenomena were studied using 630.0 nm and 777.4 nm observations: (1 highly-structured airglow depletions associated with the Rayleigh-Taylor instability/equatorial spread-F (RTI/ESF process, (2 brightness waves (BW associated with the midnight temperature maximum (MTM, (3 strong airglow enhancements associated with the positive phase of ionospheric storms, and (4 simple (non-structured bands of airglow depletions with characteristics matching a Perkins-like instability. Using 557.7 nm mesospheric observations, a fifth category of study deals with gravity waves probably generated by lower atmospheric disturbances, and mesospheric bores related to strong vertical temperature gradients. While ESF depletions and BW events are detected fairly frequently, the mid-latitude bands are not, and thus their successful imaging at El Leoncito offers the first example of the coupling from mid-latitudes to low-latitudes in the South American longitude sector. Preliminary results on these features are presented in this paper. Taken together, these five types of optical structures offer the opportunity to investigate coupling, both in altitude and latitude, of aeronomic processes at low latitudes in an under-sampled longitude sector in the Southern Hemisphere.

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

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