    2000-01-01

    Full Text Available With over 8,100 traffic fatalities in 1997 and an accident rate per 100 million vehicle kilometres travelled, approximately five times that of United States, Argentinean road authorities are now beginning to focus attention on traffic safety and driver education. One of the main problems in the search of causes for car accidents in Argentina is the lack of a reliable and updated data base. The results and conclusions presented in this paper are based on a thorough analysis of car accidents in the Province of San Juan, Argentina. A seven-year data base of car accidents has been compiled from police reports, including the results of traffic counts at intersections and other collision locations. In addition, topographic and filmed reports of such places and their surroundings bring about parameters such as stop lines, visibility triangles, road size, traffic light performance, etc., which allow to carrying out of a traffic flow analysis for proposing measures aiming to minimize accidents. For San Juan province, in general, the main causes are: high absolute car speeds, speed differences between vehicles, lack of good lighting, poor driving habits, lack of traffic control devices such as signs, signals, and an absence of road markings.

    Full Text Available This study was performed in an urban neighborhood of the capital city of the province of San Juan, Argentina. Erected as a housing complex, the place consists of 768 flats distributed in buildings of three and seven floors each. A survey was carried out in 33% of the dwellings, enquiring about the number of Triatoma infestans found indoors, stage of the bug development - nymph or adult - and how these insects had entered their homes. Adult T.infestans were found on all floors; 163 people (64% had found them at least once, and 130 (51% several times. Dispersal flight seems to have been the main mechanism of infestation by adult bugs in this area, and a total of 51% of the surveyed inhabitants reported that the insects had flown into their flats.

    The research work produces a contrasted quantification of the thermal performance of inhabited dwelling houses built in different neighborhoods of San Juan, Argentina. They correspond to five prototypes aimed at families with low and medium income levels, massive spread in their versions with two or three bedrooms. From all of them it can be obtained yearly energy consumption indexes per unit area, under homogeneous conditions respect to minimal thermal comfort levels and inhabitant behaviors. The evolution of their inner temperatures and relative humidity with and without auxiliary thermal conditioning is analyzed. Conclusions assess the deficit level of the studied prototypes contrasted to international standards and the global valuation of the impact on the sectorial annual energy consumption caused by them.

    Full Text Available We report a new record of Lithobates catesbeianus (American bullfrog from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran. The new record is for Zonda Department, San Juan Province, in the Monte desert region. Here, L. catesbeianus uses artificial ponds for reproduction and tadpole development. These ponds receive water from an irrigation system that connects the whole agriculture land in the region. The tadpoles use the irrigation canals to move among ponds. We suggest that legislation should be established to prevent future invasions and to achieve sustainable management of the wild American bullfrog populations in San Juan. Prevention of future invasion and management of established populations of this species requires the cooperation of numerous stake holders.Se presenta un nuevo registro de Lithobates catesbeianus (rana toro americana en Argentina. L. catesbeianus fue introducida por primera vez a la provincia de San Juan hace 11 años en el Departamento Calingasta, donde el hábitat es pre-cordillerano. El nuevo registro es para el Departamento Zonda en la provincia de San Juan, en el desierto del Monte. En este sitio, L. catesbeianus usa estanques artificiales para la reproducción y desarrollo del renacuajo. Los estanques reciben agua de un sistema de riego que conecta todas las tierras de la agricultura en la región. Los renacuajos utilizan los canales de riego para moverse entre los estanques. Sugerimos que se establezcan leyes para prevenir invasiones futuras y para lograr un manejo integrado de las poblaciones silvestres de rana toro que se encuentran en San Juan. La prevención de futuras invasiones y el manejo de las poblaciones establecidas de esta especie requieren la cooperación de numerosas entidades tanto gubernamentales como privadas.

    Twenty-four sampling points in the drinking water network of the City of San Juan, Argentina, were chosen in order to investigate the presence of four of the most representative trihalomethanes (THM). The collected data were statistically correlated for evaluating the seasonal variations of these substances, as well as the variations derived from their locations and distance from the drinking water treatment plant. Not any significative difference was observed Between each od the four seasons, neither between the various sampling points located at different distances from the treatment plant. The low concentrations of TOC dissolved in raw water limited the concentrations of THM whose means value did not go beyond the maximum values recommended by WHO. (Author) 22 refs.

  14. The paradigm of paraglacial megafans of the San Juan river basin, Central Andes, Argentina

    2014-11-01

    The spatial distribution and several morphometric characteristics of the Quaternary alluvial fans of the San Juan River, in the province of San Juan, at the Central and Western part of Argentina, have been studied to classify them as paraglacial megafans, as well to ratify its depositional environmental conditions. The high sedimentary load exported by San Juan river from the Central Andes to the foreland depressions is estimated about 3,682,200 hm3. The large alluvial fans of Ullum-Zonda and Tulum valleys were deposited into deep tectonic depressions, during the Upper Pleistocene deglaciation stages. The outcome of collecting remotely sensed data, map and DEM data, geophysical data and much fieldwork gave access to morphometric, morphographic and morphogenetic data of these alluvial fans. The main drainage network was mapped on processed images using QGis (vers.2.0.1). Several fan morphometric parameters were measured, such as the size, the shape, the thickness, the surface areas and the sedimentary volume of exported load. The analyzed fans were accumulated in deep tectonic depressions, where the alluvium fill reaches 700 to 1200 m thick. Such fans do not reach the large size that other world megafans have, and this is due to tectonic obstacles, although the sedimentary fill average volume surpasses 514,000 hm3. The author proposes to consider Ullum-Zonda and Tulum alluvial fans as paraglacial megafans. According to the stratigraphic relationships of the tropical South American Rivers, the author considers that the San Juan paraglacial megafans would have occurred in the period before 24 ka BP , possibly corresponding to Middle Pleniglacial (ca 65-24ka BP). They record colder and more humid conditions compared with the present arid and dry conditions.

    Arsenic (As) speciation in surface and groundwater from two provinces in Argentina (San Juan and La Pampa) was investigated using solid phase extraction (SPE) cartridge methodology with comparison to total arsenic concentrations. A third province, Río Negro, was used as a control to the study. Strong cation exchange (SCX) and strong anion exchange (SAX) cartridges were utilised in series for the separation and preservation of arsenite (As(III)), arsenate (As(V)), monomethylarsonic acid (MA(V)) and dimethylarsinic acid (DMA(V)). Samples were collected from a range of water outlets (rivers/streams, wells, untreated domestic taps, well water treatment works) to assess the relationship between total arsenic and arsenic species, water type and water parameters (pH, conductivity and total dissolved solids, TDS). Analysis of the waters for arsenic (total and species) was performed by inductively coupled plasma mass spectrometry (ICP-MS) in collision cell mode. Total arsenic concentrations in the surface and groundwater from Encon and the San José de Jáchal region of San Juan (north-west Argentina within the Cuyo region) ranged from 9 to 357 μg l(-1) As. Groundwater from Eduardo Castex (EC) and Ingeniero Luiggi (LU) in La Pampa (central Argentina within the Chaco-Pampean Plain) ranged from 3 to 1326 μg l(-1) As. The pH range for the provinces of San Juan (7.2-9.7) and La Pampa (7.0-9.9) are in agreement with other published literature. The highest total arsenic concentrations were found in La Pampa well waters (both rural farms and pre-treated urban sources), particularly where there was high pH (typically > 8.2), conductivity (>2,600 μS cm(-1)) and TDS (>1,400 mg l(-1)). Reverse osmosis (RO) treatment of well waters in La Pampa for domestic drinking water in EC and LU significantly reduced total arsenic concentrations from a range of 216-224 μg l(-1) As to 0.3-0.8 μg l(-1) As. Arsenic species for both provinces were predominantly As(III) and As(V). As

    Transmission electron microscopy (TEM) was introduced by Ruska and Knoll as a laboratory technique in 1933. Thereafter, several decades passed before the methods required for its optimal implementation were fully developed. Early uses of TEM were in Botany, rather than in Medicine; however, isolated publications did catalog the ultrastructural characteristics of several individual human tumor types. Finally, in 1968, Rosai and Rodriguez authored an important article, introducing the concept that TEM could be used for the differential diagnosis of histologically similar neoplasms. This publication heralded the steadily increasing application of TEM in anatomic pathology over the following decade, including continuing contributions by Dr. Juan Rosai. This brief review summarizes his influence on clinical electron microscopy, and lists some of the lesions for which that procedure is still a useful means of analysis.

    The infusion of the aerial parts of Gentianella multicaulis (Gillies ex Griseb.) Fabris (Gentianaceae), locally known as 'nencia', is used in San Juan Province, Argentina, as stomachic and as a bitter tonic against digestive and liver problems. The bioassay-guided isolation of G. multicaulis extracts and structural elucidation of the main compounds responsible for the antifungal and free radical scavenging activities were performed. The extracts had strong free radical scavenging effects in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (45-93% at 10 microg/mL) and ferric-reducing antioxidant power (FRAP) assay at 200 microg/mL. Demethylbellidifolin (4) had high antioxidant activity in the DPPH and FRAP assay. The dermatophytes Microsporum gypseum, Trichophyton mentagrophytes, and T. rubrum were moderately inhibited by the different extracts (MIC values of 125-250 microg/mL). Demethylbellidifolin (4), bellidifolin (5), and isobellidifolin (6) showed an antifungal effect (MIC values of 50 microg/mL), while swerchirin (3) was less active with a MIC value of 100 microg/mL. In addition, oleanolic acid (1) and ursolic acid (2) were also isolated. These findings demonstrate that Gentianella multicaulis collected in the mountains of the Province of San Juan, Argentina, is an important source of compounds with antifungal and antioxidant activities.

    1994-01-01

    Liquefaction effects generated by the 1977 San Juan Province, Argentina, earthquake (Ms = 7.4) are described. The larger and more abundant effects were concentrated in the 60-km long band of the lowlands in the Valle del Bermejo and in an equally long band along the Rio San Juan in the Valle de Tulum. Fissures in the Valle del Bermejo were up to several hundred meters long and up to several meters wide. Sand deposits, from boils that erupted through the fissures, covered areas up to tens of square meters. Fissures generally parallelled nearby stream channels. Because the Valle del Bermejo is undeveloped, these large features caused no damage. Liquefaction in the Valle del Tulum caused important or unusual damage at several localities, including the following five sites: (1) At the Barrio Justo P. Castro, a subdivision of Caucete, liquefaction of subsurface sediments decoupled overlying, unliquefied stiff sediments, producing a form of ground failure called "ground oscillation". The associated differential ground movements pulled apart houses and pavements in extension, while shearing curbs and buckling canal linings in compression at the same locality. (2) At the Escuela Normal, in Caucete, the roof of a 30-m long single-story classroom building shifted westward relative to the foundation. That displacement fractured and tilted columns supporting the roof. The foundation was fractured at several places, leaving open cracks, as wide as 15 mm. The cumulative width of the open cracks was 48 mm, an amount roughly equivalent to the 63 mm of offset between the roof and foundation at the east end of the building. The ground and foundation beneath the building extended (or spread) laterally opening cracks and lengthening the foundation while the roof remained in place. (3) The most spectacular damage to structures at the community of San Martin was the tilting of a 6-m high water tower and the toppling of a nearby pump house into a 1-m deep crater. Similarly, a small

    The Tulum Valley aquifer vulnerability and its correlation with the behavior of hydro chemical parameters related to new urban neighborhoods and uncontrolled waste disposal are discussed. A high vulnerability to contamination by substances solved in the recharge water at the San Juan river shore is estimated. A fast transport rate due to the high permeability is foreseen, as well as the existence of contamination sources related to waste disposals and populations without a sewer system. The results show that the mentioned populations and waste disposal sites are located at vulnerable zones of the area. A higher concentration of nitrates and nitrites is observed at the Southeast, due to the short permanency period of the water in the system, and to the reconcentration in zones with less permeable levels.

The efforts, strategies and resources used by these families to reach freedom for their members are presented in this paper. Based on notarial documents (freedom letters, testaments, notarial certiicates as well as parochial documents, this study reconstructs the path traversed by these families in their longing for freedom. In the processes observed here, there is evidence of the relevance of certain factors regarding to the decision of the families when freeing one of their members, such as the slave-master relationship, or their ability to gather enough economical resources for the payment.

    A geophysical survey involving seismic refraction tomography (SRT for mapping 'P' waves was carried out in Sierra Santa Clara, San Juan Province, Argentina in July 2009. The purpose of the geophysical survey was to determine the degree of fracturing and the rigidity of the rock mass through which it is planned to build a 290 m long road tunnel traversing the mountain almost perpendicular to the axis thereof, at around 100 m depth from the summit.

    Several difficulties arose from the operational point of view which made it almost impossible to conduct fieldwork in normal circumstances. Firstly, the topography had almost 45° slopes and 100 m research depths which would have involved having had to use explosives to generate seismic waves reaching sensors which had sufficient signal-to-noise ratio for distinguishing them. Legal restrictions regarding the use of explosives on the one hand and insufficient power when using hammer blows on the other made it necessary to design and build a gas-powered gun to achieve the minimum energy (2 kJ required for detecting seismic signals.

    Secondly, using conventional interpretation methods involving layered models was inoperable in such geological structures; seismic tomography methods were thus used which make use of the velocity gradient concept (both lateral and in-depth. This allowed mapping subsurface velocity variations in the form of velocity contour lines.

    The methodology used with the new seismic waves' source generator, as well as SRT application in this type of geological structure, demonstrated that satisfactory results could be obtained for this kind of geophysical study for geotechnical purposes.

    The Matagusanos-Maradona-Acequión Valley sits within the Andes Precordillera fold-thrust belt of western Argentina. It is an elongated topographic depression bounded by the roughly N-S trending Precordillera Central and Oriental in the San Juan Province. Moreover, it is not a piggy-back basin as we could have expected between two ranges belonging to a fold-thrust belt, but a very active tectonic corridor coinciding with a thick-skinned triangular zone, squeezed between two different tectonic domains. The two domains converge, where the Precordillera Oriental has been incorporated to the Sierras Pampeanas province, becoming the western leading edge of the west-verging broken foreland Sierras Pampeanas domain. This latter province has been in turn incorporated into the active deformation framework of the Andes back-arc at these latitudes as a result of enhanced coupling between the converging plates due to the subduction of the Juan Fernández ridge that flattens the Nazca slab under the South American continent. This study focuses on the neotectonics of the southern tip of this N-S elongated depression, known as Acequión (from the homonym river that crosses the area), between the Del Agua and Los Pozos rivers. This depression dies out against the transversely oriented Precordillera Sur, which exhibits a similar tectonic style as Precordillera Occidental and Central (east-verging fold-thrust belt). This contribution brings supporting evidence of the ongoing deformation during the Late Pleistocene and Holocene of the triangular zone bounded between the two leading and converging edges of Precordillera Central and Oriental thrust fronts, recorded in a multi-episodic lake sequence of the Acequión and Nikes rivers. The herein gathered evidence comprise Late Pleistocene-Holocene landforms of active thrusting, fault kinematics (micro-tectonic) data and outcrop-scale (meso-tectonic) faulting and folding of recent lake and alluvial sequences.

    Rock glaciers are frozen water reservoirs in mountainous areas. Water resources are important for the local populations and economies. The presence of rock glaciers is commonly used as a direct indicator of mountain permafrost conditions. Over 500 active rock glaciers have been identified, showing that elevations between 3500 and 4500 m asl., a south-facing or east-facing aspect, areas with relatively low solar radiation and low mean annual air temperature (-4 to 0 °C) favour the existence of rock glaciers in this region. The permafrost probability model, for Dry Andes of San Juan Province between latitudes 28º30‧S and 32°30‧S, have been analyzed by logistic regression models based on the active rock glaciers occurrence in relation to some topoclimatic variables such as altitude, aspect, mean annual temperature, mean annual precipitation and solar radiation, using optical remote sensing techniques in a GIS environment. The predictive performances of the model have been estimated by known rock glaciers locations and by the area under the receiver operating characteristic curve (AUROC). This regional permafrost map can be applied by the Argentinean Government for their recent initiatives which include creating inventories, monitoring and studying ice masses along the Argentinean Andes. Further, this generated map provides valuable input data for permafrost scenarios and contributes to a better understanding of our geosystem.

    Carbonate fault breccia dykes in the Cerro La Chilca area, Eastern Precordillera, west-central Argentina, provide clues on the probable mechanism of both fault movement and dyke injection. Breccia dykes intrude Upper Carboniferous sedimentary rocks and Triassic La Flecha Trachyte Formation. The timing of breccia dyke emplacement is constrained by cross cutting relationships with the uppermost Triassic unit and conformable contacts with the Early Miocene sedimentary rocks. This study supports a tectonic-hydrothermal origin for these breccia dykes; fragmentation and subsequent hydraulic injection of fluidized breccia are the more important processes in the breccia dyke development. Brecciation can be triggered by seismic activity which acts as a catalyst. The escape of fluidized material can be attributed to hydrostatic pressure and the direction of movement of the material establishes the direction of least pressure. Previous studies have shown that cross-strike structures have had an important role in the evolution of this Andean segment since at least Triassic times. These structures represent pre-existing crustal fabrics that could have controlled the emplacement of the dykes. The dykes, which are composed mostly of carbonate fault breccia, were injected upward along WNW fractures.

    depocenters with concentric isoanomalies of -20 mGal were determined, one at the latitude of the Calingasta village and the other situated to the SW of the locality of Barreal. The depths arising from the solutions of the localized Euler deconvolution, in the depocenters, reach 5000 meters. The distribution of the solutions of the Euler Deconvolution, as the responses of the Analytic Signal and Tilt Gradient, indicate the presence of zones with NNW-SSE and NNE-SSW trends which segment the bolson and separates both depocenters. This trends are interpreted as produced by antithetic (or conjugated) faulting, which is in accordance to seismic results. References Kokogian, D. A.; Spalletti, L.

    Background notes on Argentina provide a profile of the geography, selected demographic features, government and economic conditions. Descriptive text includes a discussion of the people, their history and political conditions, the government and officials, the state of the economy, their defense, foreign relations, and relations with the US. The 1992 estimated population was about 33 million of whom 97% are European (mostly Spanish and Italian). Religions represented are Roman Catholic (92%), Protestant (2%), Jewish (2%), and other (4%). Adult literacy is 95%. 36% are engaged in industry and commerce, 20% in services, 19% in agriculture, 6% in transport and communications, and 19% other. Per capita gross domestic product was $4,500. There are only 50,000 native Indians remaining in peripheral provinces. The population enjoys a high standard of living and a low growth rate. The country was shaped by dominant forces: modern agricultural techniques and the integration of the country into the world economy. Foreign investment aided the economic revolution. Conservative and radical rule has swung the country back and forth politically since 1916. Colonel Juan Domingo Peron led a successful military coup in 1943 and was elected in 1946. Policies were instituted to give a greater voice to the working class, and with the influences of his wife, women's groups. In 1955, he was ousted by the military, which failed to revive the economy and quiet increasing terrorism. After a number of difficult elections, Peron was reinstated as president in 1973. Extremists on the left and right threatened public order; the military as a consequence imprisoned persons indefinitely. Peron's wife succeeded him after his death, but was removed from office in the military coup of 1976. Basic human rights were violated during this period. By 1983, a fair election was held and support increased for a democratic system. In 1989, Carlos Saul Menem, a Peronist candidate, won and established

We focus on Juan Canals’s business career. He was a Catalan immigrant who arrived to Rosario (province of Santa Fe in 1870. We will look into the concepts of reputation and honorableness built from his figure, as they organized the behavior of that period, getting a particular meaning in the bourgeois world. Some of our questions ask for how did those merits influence the way the press built the image of certain businessmen who got social notoriety; how were those values perceived and defended by the actors; and how did those perceptions put in a state of tension the logics of the bourgeois universe.

    We studied the VOCs profile of three red wine varieties, produced in the Valley of Tulum (San Juan-Argentina), over 4 consecutive years. Our main goal was to verify if different wine varieties could be differentiated from their VOCs profile, considering changes induced by their age, the yeast inoculated and the type of alcoholic fermentation, establishing those compounds that could be used as chemical markers of a particular variety. Stepwise LDA of selected VOCs allowed 100% differentiation between studied wines, showing that high levels of 1-hexanol were characteristic for Malbec, while low level of ethyl caproate was characteristic for Bonarda. Using controlled fermentations, 1-hexanol, a pre-fermentative VOC, presented a similar trend in wines produced from different yeast; while other fermentative VOCs, like ethyl caproate and ethyl caprilate, presented lower levels for Bonarda but also for Syrah. To our knowledge, this is the first report on characterization of VOCs from Bonarda. Additionally, the quantitative analysis of VOCs profile, coupled to chemometrics, present a good alternative to differentiate wines from different varieties and also for studying wine fermentation.

    Full Text Available In this work framed within the functional variacionist theory that relates form, motivation and culture, we want to show how the XIX century native speaker of Spanish in San Juan, Argentina, alternates between synthetic and periphrastic devices to refer to future time according to their communicative purposes. The corpus consists of family letters written between 1837 and 1889, in the "century of political independencies and the creation of new states, in which the fight for Latin American identity begins" [Majfud, 2002]. We consider that these alternate constructions are not equivalent syntactically, semantically nor pragmatically, their use being favoured by certain parameters. Of these parameters, we analyze the one through which, we believe, the periphrastic innovation "ir a + infinitivo" started. We adhere to the fact that "the functional explanations of linguistic change do not exclude but imply cultural explanations" [Coseriu, 1977]. This pragmatic approximation to linguistic use demands at the same time a qualitative and quantitative analysis. "It will not only matter what structures language contains, but also when we recur to them, and above all, how much we use when and what structure" [García, 1995

    Palaeomagnetic data from poorly consolidated to non-consolidated late Cenozoic sediments along the central segment of the active El Tigre Fault (Central-Western Precordillera of the San Juan Province, Argentina) demonstrate broad cumulative deformation up to ~450 m from the fault trace and reveal clockwise and anticlockwise vertical-axis rotations of variable magnitude. This deformation has affected in different amounts Miocene to late Pleistocene samples and indicates a complex kinematic pattern. Several inherited linear structures in the shear zone that are oblique to the El Tigre Fault may have acted as block boundary faults. Displacement along these faults may have resulted in a complex pattern of rotations. The maximum magnitude of rotation is a function of the age of the sediments sampled, with largest values corresponding to middle Miocene-lower Pliocene deposits and minimum values obtained from late Pleistocene deposits. The kinematic study is complemented by low-field anisotropy of magnetic susceptibility data to show that the local strain regime suggests a N-S stretching direction, subparallel to the strike of the main fault.

    The Miocene Manantiales foreland basin is located in Cordillera Frontal of San Juan, between 32°30' and 33°S. The unroofing study of the synorogenic Miocene deposits provides information about the structural evolution of Cordón de La Ramada fold-and-thrust belt. These Tertiary deposits are represented by the Chinches Formation and comprise seven members (Tc0-Tc6). They are the result of the uplift of Mesozoic sequences that crop out in La Ramada fold-and-thrust belt of the Cordillera Principal. Quaternary deposits unconformably overlying the Chinches Formation are composed of granitic and rhyolitic blocks, and represent the final uplift of the Cordón del Espinacito and a series of out-of-sequence thrusts. The unroofing studies also provide sufficient information to establish the out-of-sequence timing of the deformation at this latitude. Initial deposition of the Tertiary deposits can be dated at about 20 Ma, or early Miocene. Andesitic lavas dated in 9.2±0.3, 10.7±0.7, and 12.7±0.7 Ma unconformably overlie the structure of La Ramada fold-and-thrust belt. These facts constrain the uplift of the High Andes between 20 and 10 Ma at this latitude. The unconformity between Tertiary and Quaternary deposits suggests final uplift during Pliocene-Pleistocene times.

    Large earthquakes (M w 6.5+) are often accompanied by surface rupture that has a predictable relationship with the magnitude. However, in large thrust earthquakes that have a deep (30+ km) hypocenter or fault tip, coseismic surface deformation is expressed primarily by folding rather than as rupture along the fault surface. Knowledge of source characteristics and surficial geology are required to characterize the relationship between earthquake fault slip and coseismic folding. By fully identifying and characterizing the fault plane of the M w 7.4 earthquake that occurred in 1944 in the eastern Precordillera of the Andes, destroying the city of San Juan in northwestern Argentina, we seek to relate active folding in the near-surface structures to the blind-thrust fault at depth. Coseismic deformation associated with the 1944 earthquake are secondary fault-related folding features, and there is a large discrepancy between the amount of surface rupture and the magnitude. Subtle fold-related clues at the surface represent the only potential for recognition of the occurrence of past earthquakes. This two-part study employs seismology and structural mapping to provide a new image of the Eastern Precordillera at the crustal scale. Source parameter inversion of teleseismic seismograms from the 1944 event place the hypocenter on a west-dipping plane approximately 30 km deep, which has previously been defined by microseismicity, as opposed to a surface-rupturing event in the Neogene sedimentary strata. Preliminary results from field mapping show two types of folding due to a west-dipping thrust fault with a tip at 5 km depth: a broad long-wavelength fold (~8 km) in deformed strath terraces cut into previously deformed bedrock, and short wavelength folding and faulting in the bedrock in the form of reactivation of older thrust planes. As of now, we cannot uniquely tie any one of these surficial structure to the thrust fault at depth because the pre-existing deformation in the

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

  1. Paleogene and Neogene magmatism in the Valle del Cura region: New perspective on the evolution of the Pampean flat slab, San Juan province, Argentina

    Science.gov (United States)

    2007-09-01

    The Valle del Cura region is characterized by a thick volcanic and volcaniclastic sequence that records the Tertiary arc and backarc magmatic evolution of the Argentine Main Cordillera over the modern Pampean flatslab at 29.5-30°S. During the Eocene, a retroarc basin developed, represented by the Valle del Cura Formation synorogenic volcanosedimentary sequence, which includes rhyolites and dacitic tuffs. These silicic volcanic rocks have weak arc chemical signatures and high lithophile element concentrations and are isotopically enriched relative to the late Oligocene-early Miocene volcanic rocks that followed them. Their chemical characteristics fit with eruption through a thin crust. The Valle de Cura Formation was followed by the Oligocene-early Miocene Doña Ana Group volcanic sequence, which erupted at and near the arc front west of the border with Chile. The Doña Ana Group volcanic rocks have calc-alkaline chemical characteristics consistent with parental magmas forming in a mantle wedge and erupting through a normal thickness crust (35 km). Subsequent shallowing of the downgoing Nazca plate caused the volcanic front to migrate eastward. The volcanic sequences of the middle Miocene Cerro de las Tórtolas Formation erupted at this new arc front, essentially at the Argentine border. Two stages are recognized: an older one (16-14 Ma) in which magmas appear to have erupted through a normal thickness crust (30-35 km) and a younger one (13-10 Ma) in which the steeper REE pattern suggests the magmas last equilibrated with higher pressure residual mineral assemblages in a thicker crust. Isotopic ratios in the younger group are consistent with an increase in original crustal components and crust introduced into the mantle source by forearc subduction erosion. A peak in forearc subduction erosion near 12-10 Ma is consistent with when the main part of the Juan Fernandez Ridge began to subduct beneath the region. In addition to late Miocene Tambo Formation dacitic

    Between the 28 ° and 31 ° LS parallels of the Argentinean west, in the province of San Juan, foreland basins originated by the subhorizontal subduction of oceanic crust as a result of the Andean orogeny in the late Oligocene emerges. The Bermejo basin and Rodeo-Iglesias piggy-back basin would be associated with the progressive development of landslides, backscatter and minor faults, and basin fragmentation. Two samples of volcanic rocks, R-1 (rhyolitic dome) and R-3 (fall deposit) of the Rodeo-Iglesias basin, had ages of 8.2 ± 0.11 Ma and 8.7 ± 0.24 Ma. At the same time, the age of the (R-1) made it possible to infer quantitatively the age of the first cavalcade that occurred approximately 8.2 ± 0.11 Ma. From the data obtained in the Rodeo-Iglesias basin both volcanism and the first cavalcade could have been synchronous.

    The ranges of the Sierras Valle Fértil-La Huerta expose natural cross sections through a paleo-arc crust that formed in the Late Cambrian - Early Ordovician Famatinian magmatic arc, northwestern Argentina. Thick mafic sequences of amphibole gabbronorites to orthopyroxene-amphibole-biotite diorites form the lower levels of the exposed paleo-arc section. This mafic unit includes lens-shaped bodies of olivine-bearing cumulate rocks and tabular-shaped sill/dike intrusions of fine-grained chilled amphibole gabbro. The mafic magmas were emplaced into regional metasedimentary sequences at lower crustal levels, corresponding to pressure from 5 to 7 kbar. Gabbronorites likely representing the parental magmas that fluxed into the exposed paleo-arc crust differ from primitive magmatic arc rocks in having somewhat lower Mg-number ( ca. 0.60) and compatible (Cr and Ni) trace element contents, and slightly higher Al 2O 3 contents. This difference is taken to indicate that a pyroxene-rich olivine-bearing assemblage with a bulk high Mg/Fe ratio and low Al 2O 3 content crystallized from mantle-derived melts before mafic magmas reached the crustal levels currently exhumed. However, some gabbronorites have incompatible trace element signatures typical of primitive mafic arc magmatism. Igneous rocks to some extent more evolved than those of the mafic unit make up a tonalite-dominated intermediate unit. The intermediate unit consists of a heterogeneous suite that ranges from orthopyroxene-bearing amphibole-rich diorites to biotite-rich amphibole-poor tonalites. Within the intermediate unit, chilled mafic rocks are found as a network of dikes, whereas metasedimentary migmatites appear interlayered as m-wide septa and km-long strips. The tonalite-dominated intermediate unit passes into a granodiorite batholith through a transitional zone that is up to 2-km wide. The boundary zone separating the tonalite-dominated and granodiorite-dominated units is characterized by mingling of tonalitic

    The Neutron Physics group at Centro Atómico Bariloche (CNEA, Argentina) has evolved for more than forty five years around a small 25MeV linear electron accelerator. It constitutes our compact accelerator-driven neutron source (CANS), which is dedicated to the use and development of neutronic methods to tackle problems of basic sciences and technological applications. Its historical first commitment has been the determination of the total cross sections of materials as a function of neutron energy by means of transmission experiments for thermal and sub-thermal neutrons. This also allowed testing theoretical models for the generation of scattering kernels and cross sections. Through the years, our interests moved from classic pulsed neutron diffraction, which included the development of high-precision methods for the determination of very low hydrogen content in metals, towards deep inelastic neutron scattering (DINS), a powerful tool for the determination of atomic momentum distribution in condensed matter. More recently non-intrusive techniques aimed at the scanning of large cargo containers have started to be developed with our CANS, testing the capacity and limitations to detect special nuclear material and dangerous substances. Also, the ever-present "bremsstrahlung" radiation has been recognized and tested as a useful complement to instrumental neutron activation, as it permits to detect other nuclear species through high-energy photon activation. The facility is also used for graduate and undergraduate students' experimental work within the frame of Instituto Balseiro Physics and Nuclear Engineering courses of study, and also MSc and PhD theses work.

  17. Description of a new species of Perichaena (Myxomycetes from arid areas of Argentina

    Directory of Open Access Journals (Sweden)

    Hernández-Crespo, Juan Carlos

    2009-12-01

    Full Text Available A new species of the myxomycete genus Perichaena is described in this paper. The new species, named Perichaena calongei, was found during intensive studies of arid areas of the Monte desert in Argentina. It has been found directly in the field from the provinces of Catamarca, La Rioja, Salta and San Juan, in the Northwest of Argentina, and isolated from moist chamber cultures of native plant species collected in Catamarca, Jujuy, Salta and San Juan. The characters that make this species unique in the genus are the combination of the morphology of the sporocarps, the structure and dehiscence of the peridium, and the ornamentation of the capillitium. The morphology of the my xo - mycete specimens was examined using light microscopy with Nomarski interference contrast, and scanning electron microscopy. Micrographs of relevant morphological characters are included. A key to facilitate the identification of the stipitate species of Perichaena is also proposed.

    Se describe una nueva especie, Perichaena calongei, que fue encontrada en el desierto de Monte, en las zonas áridas del nor - oeste de Argentina. Los cuerpos fructíferos se encontraron fructificados en el campo, también se obtuvieron por cultivo en cámara húmeda de plantas recolectadas en las provincias de Catamarca, Jujuy, La Rioja, Salta y San Juan. La combinación de caracteres de la morfología del esporocarpo, de la estructura y tipo de dehiscencia del peridio, y de la ornamentación del capilicio, distinguen esta especie del resto de las conocidas en el género. La morfología de la especie se analizó con un microscopio óptico dotado de contraste interferencial de Nomarski y con un microscopio electrónico de barrido, se incluyen ilustraciones de las estructuras observadas. Se propone una clave dicotómica para la identificación, a nivel mundial, de las especies estipitadas del género Perichaena.

    Directory of Open Access Journals (Sweden)

    Craig Paterson

    2015-05-01

    Full Text Available The increasingly psychological terrain of crime and disorder management has had a transformative impact upon the use of electronic monitoring technologies. Surveillance technologies such as electronic monitoring e#8209; EM, biometrics, and video surveillance have flourished in commercial environments that market the benefits of asocial technologies in managing disorderly behavior and which, despite often chimerical crime prevention promises, appeal to the ontologically insecure social imagination. The growth of EM in criminal justice has subsequently taken place despite, at best, equivocal evidence that it protects the public and reduces recidivism. Innovative developments in Portugal, Argentina and the United States have re-imagined EM technologies as more personalized devices that can support victims rather than control offenders. These developments represent a re-conceptualization of the use of the technology beyond the neoliberal prism of rational choice theories and offender-oriented thinking that influenced first generation thinking about EM. This paper identifies the socio-political influences that helped conceptualize first generation thinking about EM as, firstly, a community sentence and latterly, as a technique of urban security. The paper reviews attempts to theorize the role and function of EM surveillance technologies within and beyond criminal justice and explores the contribution of victimological perspectives to the use of EM 2.0.

    The SPM is based on photographic plates taken at our observatory at El Leoncito, Argentina and will yield absolute proper motions and positions to magnitude B 19 for approximately 1 million stars south of declination -20 degrees. The SPM is a joint program between the Yale Southern Observatory and the Universidad Nacional de San Juan, Argentina. The SPM Catalog 2.0 provides positions, absolute proper motions, and photographic BV photometry for over 320,000 stars and galaxies. All objects contained in the SPM 1.0 Catalog (the South Galactic Pole region) are also included in this version. Note that SPM 1.0 has been replaced by SPM 1.1 which has slightly different astrometry (mostly proper motions) due to refinement of the magnitude equation correction in the SPM 2.0 Catalog. The Catalog covers an area of 3700 square degrees in an irregularly bounded band between declinations of -43 and -22 degrees, but excluding fields in the plane of the Milky Way. Stars cover the magnitude range 5 astrom/. Our web-site contains several useful plots showing the sky coverage, error distribution, a quick comparison with the Hipparcos proper motions, etc.

    In 1987 Argentina had a population of 31.5 million, with an annual rate of increase of 1.6%. The total fertility rate was 3.3, and the birth rate was 24/1000 population. Mortality stood at 8/1000 population, and the infant mortality rate was 35.3/1000 live births. Life expectancy at birth is 70 years. 84% of the population lives in Argentina's urban areas. Current government policies call for regional development to maintain and increase population in rural areas and control growth in urban centers. 90% of the population is of European descent, largely as a result of high rates of immigration during the 1880s-1930s from countries such as Spain and Italy. In 1985 the gross national product per capita was US$2130. Argentina is rich in resources and almost self-sufficient in terms of basic foodstuffs, power supply, and advanced communication networks. On the other hand, political conflicts and economic crises have hindered the realization of both human and natural resource potential. 80% of the value of export products is the amount due in interest on foreign debts.

    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.

    Describes the one-man survey system which has been implemented at the San Juan surface mine in northwestern New Mexico. The Geodimeter System 4000, produced by Geotronics of Sweden, consists of a tripod-mounted electronic total station and a range rod-mounted remote positioning unit (RPU). A radio link between the tripod-mounted total station and the RPU enables one person to control the instrument and collect data. At San Juan the system has been used to survey overburden removal and mining. Only in cases where the pits become very long, and control cannot be set in the pit, is a two-person crew used. The system is useful for surveys of compliance projects and lends itself well to regrading work. 3 photos.

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

Furthermore, the Italian journey of Rizi, that involved the last 20 years of his life, has always been an enigma, resolved only in certain aspects, thanks to few news supplied by his biographers and the manuscripts the monk wrote during his staying in the Montecassino abbey. Our recent discovery of 8 new canvases painted by Rizi to decorate the Saints Cosme and Damian's chapel in the main church of Trevi nel Lazio (Frosinone, Italy, as well as the location of several new drawings in the Montecassino and Vatican libraries, will allow us to study his activity as painter in Italy and also to profile, with more accuracy, the history of the last years of his life.No disponible

    2012-09-01

    Full Text Available In Argentina there are two tephritid fruit fly species of major economic and quarantine importance: the exotic Ceratitis capitata that originated from Southeast Africa and the native Anastrepha fraterculus. In recent years, the use of fruit fly parasitoids as biocontrol agents has received renewed attention. This increasing interest has recently led to the establishment of a program for the mass rearing of five million Diachasmimorpha longicaudata parasitoids per week in the BioPlanta San Juan facility, San Juan, Argentina. The first augmentative releases of D. longicaudata in Argentina are currently occurring on commercial fig crops in rural areas of San Juan as part of an integrated fruit fly management program on an area-wide basis. In this context, research is ongoing to assess the suitability of indigenous parasitoid species for successful mass rearing on larvae of either C. capitata or A. fraterculus. The purpose of this article is to provide a historical overview of the biological control of the fruit fly in Argentina, report on the strategies currently used in Argentina, present information on native parasitoids as potential biocontrol agents, and discuss the establishment of a long-term fruit fly biological control program, including augmentative and conservation modalities, in Argentina’s various fruit growing regions.

  11. A new calymmate mimosoid polyad from the Miocene of Argentina.

    Science.gov (United States)

    Caccavari; Barreda

    2000-05-01

    A palynomorph with an unequivocal relationship to the eight-grain polyads of the mimosoid genus Calliandra Benth., is described from the Miocene sediments of San Juan Province, Argentina. Comparison of the fossil palynomorph with polyads of the extant Calliandra species shows a resemblance to those which have one, highly specialized, appendiculate monad. The new palynomorph has a rudimentary appendix, apparently transitional in the path leading to the more highly developed appendiculate forms in the extant Calliandra group. This specialized polyad type is considered to be one of the most highly evolved forms in subfamily Mimosoideae. The closest affinity of the new fossil polyad is with the eight-grain calymmate polyads of Calliandra chilensis Benth., a species which has developed in the extra-tropical, xerophilous shrub, habitat of north-central Chile. The disappearance of Calliandra species in San Juan Province is thought to be related to the culmination of the Andean rising, and the consequent interruption to the Pacific Ocean climatic influence. This new discovery is the first fossil record of Calliandra for Argentina, as well as being the most southerly and the oldest. It reinforces the hypothesis of an early origin and diversification for the Leguminosae in Tropical America.

    Full Text Available La communauté de San Juan est reconnue depuis 1939. Une première partie concerne l’organisation de la reducción de San Juan vers le milieu du XVIe siècle. Le poids fiscal s’exerce durement sur le village et la crise est générale dans toute la vallée du Chancay au XVIIe. siècle. La christianisation des habitants est définitive au milieu de ce même siècle. C’est vers la fin du XVIIe siècle et durant tout le XVIIIe que se multiplient les conflits entre San Juan et les villages voisins liés aux terrains de pâture et à la possession de l’eau. La deuxième partie du travail concerne les rapports de la communauté de San Juan avec le Pérou contemporain : contrainte fiscale toujours très lourde durant la fin de l’époque coloniale, exactions des militaires juste avant l’indépendance. La période républicaine voit toujours les conflits avec les villages voisins mais aussi la naissance de familles qui cherchent à retirer le maximum de la communauté. Les terres sont divisées et attribuées : la détérioration de l’organisation communale traditionnelle est manifeste. L4es conflits se multiplient entre petits propriétaires, mais aussi avec les haciendas voisines : c’est l’apparition d’une véritable lutte de classes. La situation actuelle est incertaine, le poids de l’économie marchande se développe avec l’exode des jeunes. Que sera la communauté San Juan à la fin de ce siècle? La comunidad de San Juan está reconocida desde 1939. La primera parte concierne a la organización de la 'reducción' de San Juan hacia mediados del siglo XVI. El peso fiscal se ejerce duramente sobre el pueblo y en el siglo XVII la crisis es general en todo el valle de Chancay.

  15. Didn’t it matter to him absolutely?: Juan Vilanova and the controversy about tertiary Man

    2011-12-01

    Full Text Available During the founding period of palaeoanthropology, the postulate about tertiary age of humankind was an outstanding subject. First proposals were based on supposed proofs about ancient lithical industry (eoliths. Some discoveries of human fossil remains complicated that issue, because they were dated as pliocene or oldest. This controversy about so-called «tertiary man» soon arrived to Spain. Juan Vilanova y Piera, palaeontologist and professor at Madrid, dealt with it from an antievolutionist point of view. When a human fossil skeleton, included in the Botet’s collection, with several apparently primitive traits arrived to Valencia from Argentina, Vilanova got reasserted and exposed his ideas about this question more intensely.

    Un tema relevante durante el período fundacional de la paleoantropología fue el postulado de la antigüedad terciaria de la humanidad. Las primeras propuestas se basaban en supuestas evidencias de industria lítica (eolitos. La cuestión se complicó con el descubrimiento de diversos fósiles humanos que fueron datados como pliocenos o incluso de mayor antigüedad. Esta polémica sobre el llamado «hombre terciario» llegó pronto a España. El paleontólogo y catedrático de la Universidad Central, Juan Vilanova y Piera, se ocupó extensamente del asunto desde perspectivas antievolucionistas. La llegada a Valencia en 1889, formando parte de la colección paleontológica donada por José Rodrigo Botet, de un esqueleto humano fósil procedente de Argentina que mostraba rasgos aparentes de primitivismo, llevó a Vilanova a reafirmarse y exponer más intensamente sus ideas sobre esta cuestión.

    2014-12-01

    Full Text Available Juan Gelman is generally considered by critics to be one of the most important poets of modern Argentina. Born in Buenos Aires in 1930 from Russian-Jewish parents, he published his first collection of poems (Violín y otras cuestiones in 1956. He is a member of the generación del 60, made up of intellectuals influenced in their critical realism by the charisma of Raúl González Tuñón, forerunner of Argentina’s social and political poetry. This group was politically very active, as demonstrated by their experimental language and iconoclastic lyricism. Gelman’s later life was marked by his exile in the wake of the 1976 dictatorship, and by the desaparición of his son Marcelo Ariel, his daughter-in-law Claudia and his grand-daughter Andrea (born in prison. Since then, it was impossible for Juan Gelman to separate his personal plight from Argentina’s historical-political situation, and his poetry became more and more intimate and lyrical, marked by human drama. La junta luz, the author’s only theatre play, was written and published in this second phase.

  11. An Inquiry into Juan Ramon's Interest in Walter Pater

    1983-01-01

    Full Text Available The evidence for Juan Ramon's interest in Pater, which began around 1920 and was still active twenty years later, is discussed in this paper. Pater's view of death and dying and his attitude toward the decadent persona are described in so far as they indicate the spiritual affinity that exists between him and Juan Ramón. Pater's aesthetic idealism, and the presence of similar ideals in Juan Ramon's own work are then examined. The second part of the paper concentrates on the great interest Juan Ramón took in Pater's evocation of the Mona Lisa. The potential impact of the aesthetic idealism inherent in this passage, its Platonism in particular, receives special analysis in the light of Espacio , and in consideration of Juan Ramon's 1943 remark: "I am, have been, and always will be a Platonist."

    2003-10-01

    Hurricane Juan hit the Halifax Regional Municipality on September 28, 2003, creating the largest outage in Nova Scotia Power's history. This detailed report documents the extensive damage that Hurricane Juan caused to the power transmission and distribution system in Nova Scotia. It also reviews the massive power restoration effort, with reference to numerous interviews, computer records and data logs which offer a wide range of observations, statistics and insights into the preparation and performance of Nova Scotia Power Inc. (NSPI) and the efforts of other key organizations following the storm. NSPI organized a recovery effort that matched the intensity of the hurricane. A fire in the Scotia Square Office Tower caused the evacuation of the company's call centre. The Tufts Cove station in Dartmouth, which generates 400 megawatts of power, was forced to shut down. Excess electricity was moved into New Brunswick and other jurisdictions to maintain system stability. The main priority was to restore customers back to service. Within 5 days of the hurricane, 95 per cent of those who lost power had service restored. Hurricane Juan caused the most damage to the transmission and distribution system in NSPI's history. Three out of five high capacity transmission lines were put out of service. Three 120-foot high transmission towers fell, and 17 main transmission lines were damaged and put out of service. Forty-five major substations were affected and 145 distribution feeders were damaged or tripped off, including 106 in the Halifax Regional Municipality. Large portions of 4,500 kilometres of local distribution lines in the Halifax Regional Municipality were damaged, including thousands of kilometers across the Northeast. The power crew, consisting of 2,000 individuals from the region and neighbouring utilities in New Brunswick and Maine, worked for 15 consecutive days to replace 275 transformers, 760 power poles, and 125,000 metres of conductor wire.

    For 26 years (1971-1997), the University of Toronto operated a very productive 60-cm optical telescope on Carnegie's Cerro Las Campanas in north-central Chile. Due to a series of cutbacks in subsidies through NSERC, Canada's research-funding agency, the doors were closed on 01 July 1997 (Canada Day). Following an agreement between astronomers at DDO (Canada) and CASLEO, Argentina, the telescope and dome were relocated on Cerro Burek in Parque Nacional El Leoncita, Argentina, just on the other side of the Andes from Ovalle, Chile. The new building is 3 meters higher and has a dozen ventilating windows. The result is unexpectedly superior seeing. The average point spread function is 0.7 arcseconds. During construction of the building and rebuilding of the telescope, all decisions were made with the intention of operating the telescope remotely, initially from the warmroom of the CASLEO 2.15 meter telescope and ultimately from Toronto and San Juan.

Se muestra en el artículo que la summa estética de Guerrero, si bien expresa con toda claridad las preocupaciones centrales de una generación intelectual marcada por la cultura alemana de entreguerras y por la problemática de la "crisis de la cultura", inscribe, a su vez, una anomalía -benjaminiana-, una inflexión político-materialista, que pone en cuestión la idea frecuente de que la "crisis de la cultura" una y otra vez diagnosticada en aquella época mostró siempre alternativas "espiritualistas" de resolución.This essay deals with the aesthetic-philosophical work of the Argentinean Luis Juan Guerrero (1899-1957, through a consideration of its early and fruitful reception of some central aspects of Walter Benjamin's work. It is shown that this perspective allows a privileged access to Guerrero's work, at the same time that it makes more complex the image of the "anti-positivistic" intellectual generation in Argentina. Guerrero's forgotten work includes principally contributions on ethics, psychology and aesthetics. This essay will pay attention only to his most important work, maybe the most ambitious aesthetic work ever written in Argentina: Operatory Aesthetics in its Three

    Commercial production from a new formation is rare in a basin as mature as the San Juan. Such a development can be economically attractive because with so many existing wellbores, behind pipe formations can be placed on production quickly and inexpensively. That is happening on the east side of the San Juan, where what appears to be the first significant commercial gas production from Tertiary Ojo Alamo sandstone started last year. The deposit is briefly described.

  18. Groundwater basin of the Tulum Valley, San Juan, Argentina: A morphohydrogeologic analysis of its central sector

    Lloret, Gustavo; Suvires, Graciela M.

    2006-07-01

    The geometry of a sector in the groundwater basin of the Tulum Valley has been studied to determine the shape, thickness, and vertical and horizontal distribution of the grain size, as well as the depositional environmental conditions of the Quaternary deposits that fill the valley. The geomorphologic features of the area have been investigated on the basis of aerial photographs checked with fieldwork. Three subsurface sections were prepared for a hydrogeological analysis of the area. These cross-sections were prepared by combining information from descriptions of well samples and interpretations of geophysical logs of wells and electric resistivity surveys. Within the studied area, the floor of the groundwater basin is asymmetrically shaped; the Quaternary deposits, which lie on an impervious or poorly pervious electrically conductive hydrogeologic basement of Late Tertiary age, reach a thickness of 670 m in the west and only 215 m in the eastern extreme. The Tulum Valley Basin is divided into two subbasins by a fault system trending NNE-SSW, which plays an important role in the configuration of the basin and the distribution of the Quaternary sediments units, as well as the distribution of aquifers in the subsurface. The western subbasin has a thicker cover and coarser grain sizes than the eastern one, where the sediments have more fine-grained intercalations and hardpans. The latter are probably pedogenic in origin.

The analysis of these texts sheds light on Palmireno’s understanding of the word and its possible implications in the sixteenth century. The study identifies an interpretation of silva as a way of writing different from his predecessor, Pedro Mexía, who first used it to title his work Silva de varia lección twenty years ago. The lack of any intention to arrange its structure gives these silvas the characteristic of a literary draft, a feature derived from one of the meanings of silva inherited from the Classical Age. Moreover, Palmireno’s works reveal an encyclopedic project of which the miscellany (represented by silva forms a part. Furthermore, the silvas of Palmireno act as a transition to the later development of silva as a genre, which finds its educational objective being taken over gradually by the anxiety to provide entertainment.El artículo examina las obras tituladas Silva de Juan Lorenzo Palmireno.

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.

    The sequence of mid-Cenozoic volcanic events in the western San Juan Mountains is closely analogous to that elsewhere in the San Juan volcanic field. The Lake Fork, Picayune, and San Juan Formations were erupted from a cluster of central volcanoes from 35 to 30 m.y. ago, when dominant activity shifted to more silicic ash-flow eruptions with accompanying caldera collapses. The Uncompahgre and San Juan calderas, each about 20 km across, formed mainly from eruption of the 28-m.y.-old Sapinero Mesa Tuff. Collapse occurred concurrently with eruption, and intracaldera tuffs accumulated to a thickness of more than 700 m. Both calderas were resurgently domed together; the northeast-trending Eureka graben formed along the distended crest of that dome. The Uncompahgre caldera was then flooded by several 27- to 28-m.y.-old ash-flow sheets from easterly sources, and also by one apparently erupted from the Silverton caldera nested within the older San Juan caldera. The Lake City caldera, located within the older Uncompahgre caldera, formed about 22.5 m.y. ago in response to eruption of the Sunshine Peak Tuff.

    San Juan Coal Company has submitted to the State of New Mexico's Mining and Minerals Division the final phase III bond release application for the approval and release of 241 acres of permitted lands at its San Juan Mine located in San Juan County, New Mexico. The SMCRA (Surface Mining Control and Reclamation Act) and New Mexico Surface Coal Mining Regulations mandate a minimum 10-year liability period following final reclamation, during which no additional treatments other than approved postmining land uses and approved interseedings may be applied to an area for which bond release is sought. Site-specific revegetation success standards must be met for two of the last four years of liability, beginning no sooner than year eight of the bonding period. Successful reclamation of the site was demonstrated by exceeding cover, production, shrub density, and diversity standards while supporting the primary postmining land use of livestock grazing. 11 refs., 1 fig., 8 tabs.

    Mental health and psychiatric diseases have always attracted people's and health authorities' attention due to its magical approach, the lack of knowledge that surrounds them, and, at the same time, the religious fear they provoke. Both have played an important role in the history of humanity, of public health politics, and of physicians. The places where psychiatric patients were treated are of historical interest, because through the historical knowledge we can identify an approach from the science and the health policies that prevailed in each age. At the beginning of the 20th century, it was developed in México a new model of hospital care attention to psychiatric patients. La Casa de Salud San Juan de Dios para Pacientes Alienados is an example; the concept "alienated patients" suggests a social and cultural perspective. This paper presents a chronological type description of one of the major institutions involved in mental health care in México. Similarly, it shows a review of the events that affected the religious order San Juan de Dios from 1901 to 2012, when the hospitaller order was reinstated in México and established the Casa de Salud San Juan de Dios para Pacientes Alienados in the town of Zapopan, Jalisco, institution that exists up to the present day and keeps participating in the mental health care in the state of Jalisco, with the current name of Servicios de Salud San Juan de Dios.

  9. Soft rocks in Argentina

    Soft rocks are a still fairly unexplored chapter in rock mechanics. Within this category are the clastic sedimentary rocks and pyroclastic volcanic rocks, of low to moderate lithification (consolidation, cemen-tation, new formed minerals), chemical sedimentary rocks and metamorphic rocks formed by minerals with Mohs hardness less than 3.5, such as limestone, gypsum, halite, sylvite, between the first and phyllites, graphitic schist, chloritic shale, talc, etc., among the latter. They also include any type of rock that suffered alteration processes (hydrothermal or weathering). In Argentina the study of low-strength rocks has not received much attention despite having extensive outcrops in the Andes and great impact in the design criteria. Correlation between geomechanical properties (UCS, deformability) to physical index (porosity, density, etc.) has shown promising results to be better studied. There are many studies and engineering projects in Argentina in soft rock geological environments, some cited in the text (Chihuído dam, N. Kirchner dam, J. Cepernic Dam, etc.) and others such as International Tunnel in the Province of Mendoza (Corredor Bioceánico), which will require the valuable contribution from rock mechanics. The lack of consistency between some of the physical and mechanical parameters explored from studies in the country may be due to an insufficient amount of information and/or non-standardization of criteria for testing materials. It is understood that more and better academic and professional efforts in improv-ing techniques will result in benefits to the better understanding of the geomechanics of weak rocks.

    Full Text Available A biodiversity survey for myxomycetes was carried out in the Monte Desert (Argentina and surrounding areas in November 2006 and late February and March 2007. Specimens were collected in seven different provinces (Catamarca, Jujuy, La Rioja, Salta, San Juan, San Luis and Tucumán, between 23º and 33º S latitude, and a total of 105 localities were sampled. Cacti and succulent plants were the most common type of substrate investigated, but shrubs and herbs characteristic of this biome were also included in the survey. Almost six hundred specimens of myxomycetes from 72 different species in 22 genera were collected either in the field, or from moist chamber cultures prepared with samples of plant material obtained from the same collecting sites. The results include 1 species new to science, Macbrideola andina three more species recently described based on material from this survey, 5 species cited for the first time for the Neotropics, 11 new records for South America and 38 new records for Argentina. Taxonomic comments on rare or unusual species are included and illustrated with photographs by LM and SEM. Data are presented on the development of some species and microenvironmental factors are discussed. An analysis of the biodiversity of myxomycetes in this area, and a comparison with other desert areas, are included.

Poseedores históricos, propietarios y desposeídos son los actores que participan en la trama. Atravesando el juego, se encuentra el Estado en sus distintos niveles, que con cierta autonomía relativa, regula a favor de unos y en detrimento de otros. Este trabajo se propone aportar datos empíricos sobre algunas tensiones territoriales en la provincia de San Juan y el rol del Estado y sus contradicciones en los distintos niveles. El caso gira en torno a la disputa por la tierra, generando tensiones políticas entre propiedad privada y propiedad comunitaria, o entre el derecho civil y los derechos emanados de la Constitución Nacional, los Tratados Internacionales y la Ley de Bosques Nativos N° 26.331. ABSTRACT The fight about lands has been became in a relevant situation for the argentine politics in the 20th century, the historic owners, and dispossessed are the most important actors. The state through its different levels has a certain kind of autonomy and regulate and take actions which tend to favor some social groups and damage others. In this work is proposed give some empirical facts about territorial tensions in the province of San Juan, its role and contradictions in its different levels. The case revolves around the land dispute, generating political tensions between private property and communal property, or between civil law and rights arising out of the National Constitution, international treaties and Native Forest Law, No. 26.331.

    Full Text Available This article analyzes the trajectory of two secret organizations that were formed between 1835 and 1840. The first appeared in Uruguay and the second in Buenos Aires, and both were created for the purpose of overthrowing the regime of Juan Manuel de Rosas in Argentina. Despite the fact that neither was completely successful in achieving said objective, the article aims to reveal their strategies, their communication systems, their plans and the internal relations among their members. The conclusion is that these lodges played a determining role in the complex machinery of opposition since they constituted an important component in the persistent drive to oust Rosas, which would not be completely successful until the battle that finally liquidated him in Caseros (1852.

    Full Text Available Este artigo tem como objetivo destacar algumas das principais ideias do economista e pensador argentino do século XIX, Juan Bautista Alberdi. Tal interpretação se baseia em duas das suas principais obras: Bases y Puntos de Partida para La Organización Política de La República Argentina, escrito originalmente em 1852, e sua obra póstuma, Estudios Económicos, publicada originalmente em 1886. Juan Bautista Alberdi foi jurista, escritor, jornalista e economista, sempre preocupado com a construção da nacionalidade de uma região que seria a atual Argentina em um dos momentos iniciais da expansão do capitalismo cujo centro de interesse era a Inglaterra. Procurou entender seu país a partir de uma perspectiva liberal, porém considerando as estruturas locais. Defendeu, no processo, a inclusão social e regional, uma melhor divisão de poder e um federalismo fiscal mais justo para a região. Foi muito além da defesa da simples divisão internacional do trabalho. Se, no início da sua vida intelectual, colocava-se como um pensador otimista, com o decorrer dos acontecimentos, particularmente durante a segunda metade do século XIX, olhou com desconfiança e pessimismo para o processo de construção do liberalismo argentino conduzido pela cidade de Buenos Aires.

    Full Text Available This article is based on an unpublished contract signed in 1539 by Vicente and Juan Macip for an altarpiece for the Valencian Brotherhood of the Blood of Christ. The agreement stipulates that Juan, later known as Juan de Juanes, had to paint the scenes. Thus the document reinforces the hypothesis that Juan Macip was the most important painter in the Macip workshop during the 1530’s. It also fills a documental void in between the completion of the Silversmith’s Guild altarpiece (1534-1539 and the contract for the Fuente la Higuera altarpiece (1548. This study also verifies the popularity of the iconography of the seven sheddings of the Blood of Christ and processions of disciplinants.

    2000-01-01

    Juan Gabriel's purported effeminacy and sexuality have made him a controversial subject in Mexico, but still loved by fans. Juan Gabriel, by trying to gain acceptance into Mexican society, has become part of a hybrid culture, between the feminine/masculine and homosexual/bisexual/heterosexual groups. This study focuses on interviews with 20 participants who discuss Juan Gabriel's popularity and sexuality. The findings of the study indicate that Juan Gabriel may be considered by his fans to be effeminate, and consequently homosexual. Even though homophobia is widespread in Mexico, Juan Gabriel's fans tend to ignore or exoticize his sexuality, thus affording his success. It is also possible that Juan Gabriel, consciously or not, uses his controversial sexuality as a way to generate popular interest.

    The Cherenkov Telescope Array (CTA) Project will consist of two arrays of atmospheric Cherenkov telescopes to study high-energy gamma radiation in the range of a few tens of GeV to beyond 100 TeV. To achieve full-sky coverage, the construction of one array in each terrestrial hemisphere is considered. Suitable candidate sites are being explored and characterized. The candidate sites in the Southern Hemisphere include two locations in Argentina, one in San Antonio de los Cobres (Salta Province, Lat. 24:02:42 S, Long. 66:14:06 W, at 3600 m.a.s.l) and another one in El Leoncito (San Juan Province, Lat. 31:41:49 S, Long. 69:16:21 W, at 2600 m.a.s.l). Here we describe the two sites and the instrumentation that has been deployed to characterize them. We summarize the geographic, atmospheric and climatic data that have been collected for both of them.

    2013-08-01

    In 1554 Juan Valverde de Amusco, a Spanish anatomist, wrote the History of the composition of the human body, a complete anatomical treatise that took as its model the Vesalius school of thought (La fábrica of Vesalius). Considered one of the most complete anatomical treatises of the Renaissance and one of the most widely read books of the sixteenth century, it was translated into four languages in its day. The first chapter, devoted to bones, provides a meticulously detailed analysis of the bones of the facial structures and of the teeth, their supporting structures, vascularisation and innervation. Juan Valverde de Amusco even describes techniques for reducing mandibular luxations. Even with the imprecise observations typical of the time the treatise must be considered an exceptional document.

    Propolis is extensively used in Argentine folk medicine. Alcoholic extracts of propolis from different regions of Argentina were prepared. The extracts were analysed for the determination of total flavonoid content (from 13.3 to 42.6 mg/g of propolis) by using the aluminum nitrate method, UV spectrophotometry and thin layer chromatography. All of them contained high total flavonoid content. It was also observed that all samples of ethanolic extracts of propolis showed free radical-scavenging activity in terms of scavenging of the radical DPPH but the highest activities were found for samples from Tucumán and Santiago del Estero. In all cases with 20 microg/ml of soluble principles, the percentage of DPPH degradation was different (Banda Oeste: 67.5%; Verónica: 45%; Forres: 35%; Saenz Peña: 20% and Juan José Castelli: 55%). These results may justify their use as a source of natural antioxidants.

The objective of this research was to conduct a historical ecotoxicological assessment of the San Juan de Santiago de Cuba ecosystem. This was considered a systematic environmental monitoring which ran from 2010 to 2013, made q?uarterly. Physicochemical parameters such as electrical conductivity, total alkalinity, total hardness, pH, total solids, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were determined. All parameters of environmental risk prediction were performed using the GECOTOX program. The concentrations of Cu, Zn, Pb and Cd on three target organs (brain, gills and liver in the biomonitor adult Gambusia punctata (Poecilidae were analyzed. In this species, the effect of total protein and enzymatic activity of acetylcholinesterase as biomarkers were evaluated. In general, the parameters were outside the values set used by the Cuban quality standards. The GECOTOX program said that the waters of the San Juan ecosystem presented a high rate of risk. The highest concentrations of metals were determined in the gills, liver and brain, respectively. Biomarker values w? ere high, being higher for females. Finally, it was concluded that from one year to another all responses were ascending; thus, the San Juan ecosystem presented ecotoxicological effects in time.

    Full Text Available Tick paralysis (TP occurs worldwide and is caused by a neurotoxin secreted by engorged female ticks that affects the peripheral and central nervous system. The clinical manifestations range from mild or nonspecific symptoms to manifestations similar to Guillain-Barré syndrome, bulbar involvement, and death in 10% of the patients. The diagnosis of TP is clinical. To our knowledge, there are no formal reports of TP in humans in South America, although clusters of TP among hunting dogs in Argentina have been identified recently. In this paper, clinical features of two cases of TP occurring during 1994 in Jujuy Province, Argentina, are described.

Estas estimaciones dan evidencia de que las instalaciones en la planta de San Juan Ixhuatepec tenían un nivel de riesgo moderado lo cual se contrapone a la percepción de la sociedad en relación al riesgo de la compañía Pemex, propietaria de la planta. Este trabajo concluye que el accidente fue principalmente debido a errores humanos, así como a la pésima ubicación de la planta.The Dow fire and explosion index and the quantitative risk assessment methodology are applied to analyze one of the most unfortunate accidents in Mexican history: the explosion of gas storage tanks at the San Juan Ixhuatepec plant in Mexico.

The results give evidence that facilities in San Juan Ixhuatepec had a moderate risk level which is in disagreement with people’s perception of the Pemex company, proprietary of the plant. This study concludes that the accident was mainly due to human error, as well as the inappropriate location of the plant.

  1. Intermontane eolian sand sheet development, Upper Tulum Valley, central-western Argentina

    Directory of Open Access Journals (Sweden)

    Patrick Francisco Fuhr Dal' Bó

    Full Text Available ABSTRACTThe intermontane Upper Tulum eolian sand sheet covers an area of ca. 125 km² at north of the San Juan Province, central-western Argentina. The sand sheet is currently an aggrading system where vegetation cover, surface cementation and periodic flooding withhold the development of dunes with slipfaces. The sand sheet surface is divided into three parts according to the distribution of sedimentary features, which reflects the variation in sediment budget, water table level and periodic flooding. The central sand sheet part is the main area of eolian deposition and is largely stabilized by vegetation. The sedimentary succession is 4 m thick and records the vertical interbedding of eolian and subaqueous deposits, which have been deposited for at least 3.6 ky with sedimentation rates of 86.1 cm/ky. The construction of the sand sheet is associated with deflation of the sand-graded debris sourced by San Juan alluvial fan, which is available mainly in drier fall-winter months where water table is lower and wind speeds are periodically above the threshold velocity for sand transport. The accumulation of sedimentary bodies occurs in a stabilized eolian system where vegetation cover, thin mud veneers and surface cementation are the main agents in promoting accumulation. The preservation of the sand sheet accumulations is enabled by the progressive creation of the accommodation space in a tectonically active basin and the continuous burial of geological bodies favored by high rates of sedimentation.

    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.

    In 2010, in cooperation with the Mining and Minerals Division (MMD) of the State of New Mexico Energy, Minerals and Natural Resources Department, the U.S. Geological Survey (USGS) initiated a 4-year assessment of hydrologic conditions at the San Juan coal mine (SJCM), located about 14 miles west-northwest of the city of Farmington, San Juan County, New Mexico. The mine produces coal for power generation at the adjacent San Juan Generating Station (SJGS) and stores coal-combustion byproducts from the SJGS in mined-out surface-mining pits. The purpose of the hydrologic assessment is to identify groundwater flow paths away from SJCM coal-combustion-byproduct storage sites that might allow metals that may be leached from coal-combustion byproducts to eventually reach wells or streams after regional dewatering ceases and groundwater recovers to predevelopment levels. The hydrologic assessment, undertaken between 2010 and 2013, included compilation of existing data. The purpose of this report is to present data that were acquired and compiled by the USGS for the SJCM hydrologic assessment.

    优良站址的选择是射电望远镜完成既定科学目标并实现高效运行的重要保障。影响射电望远镜选址的主要因素包括电磁环境、水文、气象、地质条件、隔离性与可及性等。对于射电天文观测而言,来自宇宙天体的射电信号往往极其微弱,对望远镜系统及设备的灵敏度要求极高。然而,随着人类活动的不断加强,人们日常工作和生活中使用的电子通讯设备越来越多,无线电干扰源呈爆炸式涌现。在射电望远镜选址工作中,进行电磁环境监测,选择一个电磁环境良好的站址,对于射电望远镜实现常规观测运行、获取有效数据资料至关重要。同时,电磁环境监测结果也是射电望远镜接收机系统研制、站址电磁环境及无线电宁静区立法保护的重要依据。中阿天文学者和技术人员历时1年半完成了16个候选站址的初步勘察,并对优选出的3个主要候选站址进行了深入细致的电磁环境监测工作,获得了大量可靠数据。中阿双方依据电磁环境监测结果并结合各主要候选站址的水文、气象、地质及道路等条件,最终将位于Talacasto戈壁的3号候选站址确定为中阿CART射电望远镜的建设站点。%The China-Argentina Radio Telescope (CART) with a diameter of 40-m will be located in the San Juan province of Argentina. CART is destined to be eventually equipped with L, S, C, X, Ku, K, Ka, and possibly also Q bands. Up to date, radio telescopes are usually designed with high sensitivities eligible for detecting extremely weak radio signals from astronomical ob jects. However, the explosive utilization of large mass of electronics and radio communication facilities in human activities has significantly ruined the working environment of radio telescopes. Therefore, the selection of a radio quiet site is one of the most critical issues for locating radio telescopes such as CART. Measurements of

    Full Text Available The richness of the cultural values found in the Argentinean Andean communities is integrated by a varied diversity of genetic resources, the development of a sustainable agriculture, and the conservation of the producer's own seeds. Local agriculture is a family economic activity, in which traditional varieties of vegetable landraces are highly appreciated for their flavour, colour and aromas. However; social, economic and environmental factors have an effect on crop diversity conservation. The main aim of this work was to retrieve and maintain a representative collection of traditional crop genetic resources still cultivated in the District of Valle Fértil, San Juan Province, Argentina, and to document the farmers' crop experiences and uses. Fifty families were interviewed; 26 of these donated a total of 49 samples belonging to eight species. The landraces collected showed a geometric distribution, typical of communities with low number of species; and a pattern of dominance. A few species are present in almost all farms while rare species are found in specific environments. Local germplasm recovery can prevent genetic erosion, so that both the formal breeding sector and the farmers can make use of the diversity of this collection.La riqueza cultural de las comunidades andinas de la Argentina está integrada por la diversidad de sus recursos genéticos, el desarrollo de un sistema agrícola sostenible y por el mantenimiento de sus semillas.

    The region of central Chile offers a unique opportunity to study the links between the subducting Juan Fernandez Ridge, the flat slab, the double seismic zone (DSZ), and the absence of modern volcanism. Here we report the presence and characteristics of the first observed DSZ within the intermediate-depth Nazca slab using two temporary seismic catalogs (Ovalle 1999 and Chile Argentina Seismological Measurement Experiment). The lower plane of seismicity (LP) is located 20-25 km below the upper plane, begins at 50 km depth, and merges with the lower plane at 120 km depth, where the slab becomes horizontal. Focal mechanism analysis and stress tensor calculations indicate that the slab's state of stress is dominantly controlled by plate convergence and overriding crust thickness: Above 60-70 km depth, the slab is in horizontal compression, and below, it is in horizontal extension, parallel to plate convergence, which can be accounted for by vertical loading of the overriding lithosphere. Focal mechanisms below 60-70 km depth are strongly correlated with offshore outer rise bend faults, suggesting the reactivation of preexisting faults below this depth. The large interplane distances for all Nazca DSZs can be related to the slab's unusually cold thermal structure with respect to its age. Since LPs globally seem to mimic mantle mineral dehydration paths, we suggest that fluid migration and dehydration embrittlement provide the mechanism necessary to weaken the rock and that the stress field determines the direction of rupture.

  11. Anaglyph: Patagonia, Argentina

    Science.gov (United States)

    2000-01-01

    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 (bright 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 (dark lakes with bright shores). 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 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.

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. In doing so, each point in the image is shifted slightly, depending on its elevation. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions.Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972.

  16. Pediatric intensive care in Argentina.

    Schnitzler, E J

    1993-09-01

    8.2% of the gross domestic product is spent annually on health care in Argentina, a country of 32 million people. There is 1 medical doctor of every 147,000 beds in a total 3180 hospitals. The infant mortality rate in Argentina is 24.5/1000 live births which is high compared to developed countries. Perinatal causes and congenital anomalies are the main cause of death after the neonatal period, and accidents, cardiac disease, and respiratory tract infections are the main causes of death among children over age 1 year. Argentina has approximately 35 pediatric intensive care units (ICU), but 154 of 244 beds are within or near the capital. Only 2 hospitals have pediatric intensive care fellowship programs, so full time dedicated staff is rare. 250 registered pediatricians dedicated to intensive care are in the Argentine Pediatric Society and the nurse/bed ratio is 1:2-1:3. Moreover, the country has neither postanesthesia recuperation units, burn units, chronic ventilation units, nor approved home assistance programs, and intermediate care is not clearly standardized. These inadequacies have led to a shortage of beds and the caring for of critically ill children in general pediatric or emergency wards in hospitals which lack adequate equipment; patients are often discharged inappropriately to clear bed space. Even so, prehospital and emergency room care tends to be provided without the necessary coordination with the pediatric ICU, and structural conditions regarding electrical self-sufficiency, air conditioning, and circulation are met in only few units. Despite the existence of these adverse conditions for the care of critically ill children, a pediatric organ transplant program developed since 1987 has demonstrated 70% to 100% survival rates for 16l orthotopic liver and 9 heart transplants, respectively. Alternatives to improving intensive care in Argentina include optimizing the response of emergency and critical care delivery systems, categorizing hospitals and

    Full Text Available La obra proyectada y construida por Juan O’Gorman a lo largo de su vida traza un recorrido largo y sincopado entre formas de entender la arquitectura totalmente antagónicas. Su primera etapa de radical racionalismo desarrolla, según procedimientos estrictamente técnicos, un lenguaje revolucionario basado en la austeridad y la precisión. A pesar de ello muchas de sus obras destacan por la plasticidad de sus composiciones volumétricas, la riqueza espacial o, incluso, por la creación de atmósferas oníricas. Los primeros años de frenética actividad dan paso a un periodo de voluntario alejamiento de la práctica profesional de la arquitectura: ni una sola obra, ni un solo proyecto durante cerca de 15 años. Tan solo su actividad docente le mantiene en contacto con el mundo de la arquitectura. Cuando Juan O’Gorman vuelve a ejercer como arquitecto, lo hace construyendo algunos de los iconos del movimiento de integración plástica de México: la biblioteca central de la UNAM y su casa en San Jerónimo. A pesar de las enormes diferencias, o más bien oposiciones, entre unos momentos y otros, puede identificarse una invariante clara como señal de identidad personal: una velada voluntad de no ser arquitecto

    In July 1990 the company Iberduero, now Iberdrola, decided to carry out a development project using the Spanish technology SCAP in the Pasajes de San Juan power plant. This methodology, featured by the utilization of adaptive predictive control methodology, had been successfully applied in order to achieve the optimization of other industrial processes. The ultimate aim of this project was the replacement of the power station conventional control system, with a SCAP control system with a distributed structure able to optimize the electric energy generation process by optimizing power station operation, maximizing efficiency and working life, reducing maintenance costs, and increasing safety and availability. The project was divided into two stages to evaluate the quality of SCAP technology in the control and optimization of a power station. In the present report, the results obtained in the control of the most critical variables during the power station operation are gathered together. Beforehand, and in order to place these results in a suitable context, the project proceedings summarized in the following phases are considered: the SCAP technology; problems in a thermal power plant; and the Pasajes de San Juan power plant and its control system. The results are presented through comparative graphs that show the performance of the SCAP system as compared to the power station conventional control. 17 figs., 4 tabs., 11 refs.

Identifies the presence of inflexions and continuities in this moment of hegemonic recomposition, which some authors call of "post neo-liberal neo-developmentalist phase", fruit of the correlations of forces resulting in the general movement of the society. Therefore, addresses, in first place, the neo- liberal reaction in the mark of the capitalist crisis and the logic configuration of the accumulation in a flexible standard. In second place it analyzes the context of crisis from the beginning of the 21st century, highlighting the inflexions and continuities with the neo-liberalism and characterizing the behavior of the main socioeconomic indicators. In third place , discusses the reactions to neo-liberalism and the neo-developmentalist recomposition observed in Argentina as well in some national experiences in the latin american region, identifying continuities and ruptures. For last , taking as reference this context, it analyzes the orientation of the social policies after the 2001 crisis, putting in discussion the state action and its politics with the projects of society that are in dispute in Argentina nowadays.

  4. Juan José Saer’s La grande: another turn, the last, spiral one

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Juan José Saer (1937–2005 was born in the province of Santa Fe, located in the river coastal region of Argentina, and lived there until 1968. He then moved to Paris until his death, where he also wrote most of his works. His literary project is based on a region – the zone – which represents simultaneously geography and existence: it has a real point of reference, a portion of the Santa Fe riverside area of the Paraná river, and also it is a condition for the opportunity for a conversation between friends; a debate over the representational possibilities of language, the relationship between literature and reality, the twists and turns of philosophy. The characters, native to that region, appear throughout his work; they grow old along with their maker. Each novel completes fictional configurations, progresses both in its conflicts and in those of the group they make up. Their Leitmotiven are remembrance, memory, perception and representation of time in several manifestations. La grande, a posthumous novel, is considered a compendium of Saer’s works. It is composed of seven chapters named after the days of the week, from Tuesday to Monday. The last chapter, Monday, which Saer may have conceived as a coda, consists of a single line. His death does away with time bringing an end to his literary project. This paper comprises an analysis of temporal representation in the novel: the aging of the characters in the saga; the construction of space-time coordinates for narrative development, the formal means used for its representation, the embedding of the historical time through references to Argentina’s last dictatorship, and the functionality of the reference to the days of the week for identifying the respective chapters, both in the context of the novel and the author’s work as a whole.

    Wild and domestic animals and their by-products are important ingredients in the preparation of curative, protective and preventive medicines. Despite the medicinal use of animals worldwide, this topic has received less attention than the use of medicinal plants. This study assessed the medicinal use of animals by mestizo communities living near San Guillermo MaB Reserve by addressing the following questions: What animal species and body parts are used? What ailments or diseases are treated with remedies from these species? To what extent do mestizo people use animals as a source of medicine? Is the use related to people's age? We conducted semi-structured interviews with 171 inhabitants (15-93 years old) of four villages close to the Reserve: Tudcúm, Angualasto, Malimán and Colangüil. We calculated the informant consensus factor and fidelity level to test homogeneity of knowledge and to know the importance of different medicinal uses for a given species. The medicinal use of animals was reported by 57% of the surveyed people. Seven species were mentioned: Rhea pennata, Lama guanicoe, Puma concolor, Pseudalopex sp., Lama vicugna, Lepus europaeus and Conepatus chinga. Several body parts were used: fat, leg, bezoar-stone, stomach, feather, meat, blood, feces, wool, and liver. The fat of R. pennata was the most frequently used animal part, followed by the bezoar stone and the leg of L. guanicoe. Animals were used to treat 22 ailments, with respiratory and nervous system disorders being the most frequently treated diseases with a high degree of consensus. Old people used animals as remedies more frequently than young residents, showing some differences among villages. A low number of animal species was mentioned as used for medicinal purposes, which could be explained by the perception of strong control related the legislation that bans hunting and the erosion of traditional knowledge produced by mestizaje. However, the presence of a traditional medicine is deeply rooted in the community culture. Management strategy for protected areas should focus not only on the conservation and sustainability of biological resources, but also on the ancestral knowledge of local communities, such as the medicinal use of animals.

    This study is one of a series of studies appraising the waterbearing properties of the Navajo Sandstone and associated formations in southern Utah.  The study area is about 4,600 square miles, extending from the Utah-Arizona State line northward to the San Juan-Grand County line and westward from the Utah-Colorado State line to the longitude of about 109°50'.Some of the water-yielding formations are grouped into aquifer systems. The C aquifer is comprised of the DeChelly Sandstone Member of the Cutler Formation.  The P aquifer is comprised of the Cedar Mesa Member of the Cutler Formation and the undifferentiated Cutler Formation. The N aquifer is comprised of the sedimentary section that includes the Wingate Sandstone, Kayenta Formation, Navajo Sandstone, Carmel Formation, and Entrada sandstone.  The M aquifer is comprised of the Bluff Sandstone Member and other sandstone units of the Morrison Formation.  The D aquifer is comprised of the Burro Canyon Formation and Dakota Sandstone.  Discharge from the ground-water reservoir to the San Juan River between gaging stations at Four Corners and Mexican Hat is about 66 cubic feet per second.The N aquifer is the main aquifer in the study area. Recharge by infiltration of precipitation is estimated to be 25,000 acre-feet per year.  A major ground-water divide exists under the broad area east of Monticello.  The thickness of the N aquifer, where the sedimentary section is fully preserved and saturated, generally is 750 to 1,250 feet.   Hydraulic conductivity values obtained from aquifer tests range from 0.02 to 0.34 foot per day.  The total volume of water in transient storage is about 11 million acre-feet. Well discharge somewhat exceeded 2,340 acre-feet during 1981.  Discharge to the San Juan River from the N aquifer is estimated to be 6.9 cubic feet per second. Water quality ranges from a calcium bicarbonate to sodium chloride type water

Gieysztoria namuncurai n. sp. joins the seven species of the genus known in Argentina. The ultrastructural characteristics of the stylet place it in the Inaequales group, with complex stylets.

  16. HISTORIA DE UN CONSENSO. UN RECORRIDO POR LAS MIRADAS HISTORIOGRÁFICAS SOBRE JUAN ÁLVAREZ

    Full Text Available Aún el más breve recorrido por las opiniones de los historiadores contemporáneos sobre la obra de Juan Álvarez nos muestra, rápida y claramente, un balance extremadamente positivo de la misma. Autores de las más variadas orientaciones historiográficas, políticas e ideológicas (ya sean de la Academia, renovadores annalistas, revisionistas, marxistas coinciden en resaltar a Álvarez como uno de los mejores representantes de los estudios históricos argentinos, en particular de la historiografía económica argentina. Pero este extenso consenso encierra también una paradoja, o más evidentemente la sospecha, que tan disímiles orientaciones difícilmente puedan estar hablando del mismo Álvarez. Partiendo entonces de ese consenso, en este artículo pretendo adentrarme, en primer lugar, en esas valoraciones de la obra de Álvarez, en un recorrido que parte desde sus mismos contemporáneos hasta la historiografía actual, al tiempo que se intenta ir bosquejando un panorama que también recorra un arco extenso de las orientaciones historiográficas argentinas. En segundo término, pretendo indagar sobre qué aspectos de la obra de Álvarez se construyen tales valoraciones (particularmente sobre el rol fundante de la historiografía económica, pero también sobre el de un enfoque regional de la historia argentina, el de promotor germinal de una historia social, o el de la necesaria y explícita articulación de sus indagaciones históricas con las preocupaciones del presente, etc. y cómo éstos son resignificados tanto en relación a las orientaciones más generales de las tradiciones historiográficas, como a las coyunturas en las que fueron formuladas. En definitiva, lo que se quiere marcar es como las miradas sobre Álvarez construyen una especie de calidoscopio en el cual las múltiples interpretaciones toman aspectos de la obra, efectivamente existentes la mayor parte de ellos, que dan como resultado ese consenso del que habl

    Full Text Available En este trabajo se analiza el sistema de fallamiento existente en la depresión tectónica de Tulum, ubicada en la parte este y sur de la provincia de San Juan, en el oeste árido de Argentina. El límite entre los dos sistemas morfoestructurales, uno la Precordillera Oriental y el otro el Sistema Pampeano Occidental ha sido establecido en trabajos anteriores, a lo largo del sistema de fallamiento de Tulum, que cruza a la depresión diagonalmente en dirección NNE. No obstante la disponibilidad de nueva información de sondeos eléctricos verticales y de algunas perforaciones para búsqueda de agua subterránea, efectuados al sur y al oeste del cerro Valdivia, permite señalar que hacia el suroeste de este núcleo de basamento metamórfico limitado en ambos flancos por fallas, el límite Sistema Pampeano y Precordillera se aproxima al cordón montañoso de sierra Chica de Zonda, continuando al sur en el cerro Salinas. De allí al SSO existen, en superficie, indicaciones de que el sistema de fallamiento continúa hasta el Montecito, donde el sistema pampeano de fallas queda interrumpido por la gran falla con actividad cuaternaria que sirve de límite oriental a la sierra de Las Peñas. El contacto entre ambos sistemas forma el extremo sur de la Precordillera Oriental en subsuelo. Este conocimiento estructural permite no solo ser aplicado a la prospección de agua sino también a la de hidrocarburos en la región.An analysis is made of the fault system in the Tulum tectonic depression, situated in the southeastern part of the province of San Juan, which is in the arid western part of Argentina. The boundary of two morphostructural systems occurs in this valley: the eastern Andean Precordillera and the western Pampean ranges. In former studies it was found that this boundary runs along a fault system that crosses the Tulum depression with a NNE trends.

    Full Text Available Resumen: Juan de Robles es uno de los más brillantes humanistas de nuestro Siglo de Oro, entre cuyas obras destaca El culto sevillano (1631. En este trabajo se analizan sus ideas educativas, centradas en la relación entre la ortografía y el aprendizaje de la escritura. Entre las ideas pedagógicas de Juan de Robles es muy relevante el rechazo vehemente de la ortografía fonética, entre otros motivos, porque no favorecía el aprendizaje de la lectura y de la escritura; en consecuencia, censura la creación de nuevas letras y de un nuevo orden para el alfabeto español. Los ortógrafos defensores de la ortografía fonética en el siglo XVII argumentaban que la nueva escritura permitiría a los niños aprender a leer y a escribir con más rapidez y facilidad; así como que la creación de nuevas letras y el establecimiento de un nuevo orden del alfabeto facilitarían su enseñanza. Frente a estas pretensiones, Juan de Robles defendió el alfabeto tradicional y la ortografía etimológica de origen latino porque eran los instrumentos adecuados para la alfabetización en nuestra lengua. También critica los colegios jesuitas y la Ratio Studiorum; las principales discrepancias entre la pedagogía de la Compañía de Jesús y las ideas educativas de Juan de Robles podrían concretarse en la primacía del español sobre el latín, y en el uso de cuentos y refranes populares para la educación en El culto sevillano. En conclusión, con la obra de Juan de Robles se incorpora definitivamente el argumento pedagógico que relaciona la ortografía y la gramática españolas con el aprendizaje de la lectura y de la escritura a la polémica sobre la ortografía española del Siglo de Oro, en defensa de la ortografía etimológica frente a las pretensiones de imponer una ortografía fonética en el primer tercio del siglo XVII. Abstract: Juan de Robles is considered one of the main humanists in the Spanish Golden Century. The most important of his works is

  19. Central San Juan caldera cluster: regional volcanic framework

    Science.gov (United States)

    Lipman, Peter W.

    2000-01-01

    Eruption of at least 8800 km3 of dacitic-rhyolitic magma as 9 major ash-slow sheets (individually 150-5000 km3) was accompanied by recurrent caldera subsidence between 28.3 and about 26.5 Ma in the central San Juan Mountains, Colorado. Voluminous andesitic-decitic lavas and breccias were erupted from central volcanoes prior to the ash-flow eruptions, and similar lava eruptions continued within and adjacent to the calderas during the period of explosive volcanism, making the central San Juan caldera cluster an exceptional site for study of caldera-related volcanic processes. Exposed calderas vary in size from 10 to 75 km in maximum diameter, the largest calderas being associated with the most voluminous eruptions. After collapse of the giant La Garita caldera during eruption if the Fish Canyon Tuff at 17.6 Ma, seven additional explosive eruptions and calderas formed inside the La Garita depression within about 1 m.y. Because of the nested geometry, maximum loci of recurrently overlapping collapse events are inferred to have subsided as much as 10-17 km, far deeper than the roof of the composite subvolcanic batholith defined by gravity data, which represents solidified caldera-related magma bodies. Erosional dissection to depths of as much as 1.5 km, although insufficient to reach the subvolcanic batholith, has exposed diverse features of intracaldera ash-flow tuff and interleaved caldera-collapse landslide deposits that accumulated to multikilometer thickness within concurrently subsiding caldera structures. The calderas display a variety of postcollapse resurgent uplift structures, and caldera-forming events produced complex fault geometries that localized late mineralization, including the epithermal base- and precious-metal veins of the well-known Creede mining district. Most of the central San Juan calderas have been deeply eroded, and their identification is dependent on detailed geologic mapping. In contrast, the primary volcanic morphology of the

    That deglaciation influences mid-ocean ridge volcanism is well established for Iceland, where depressurization associated with melting a ~2 km ice cap led to order of magnitude increases in volcanism during the last deglaciation. The case was also made that the more subtle ~100 m changes in sea level that accompany glacial cycles have identifiable implications for undersea mid-ocean ridge systems using both models and data from the Australian-Antarctic Ridge (Crowley et al., 2015). Sea level rising at ~1 cm/year during deglaciation leads to an expectation of ~10% decreases in melt production at ridges, given mantle upwelling rates of ˜3 cm/yr at intermediate spreading ridges and mantle density being ~3 times that of seawater. The implications of variations in melt production for bathymetry, however, involve numerous considerations, including whether melt signals are cancelled within the melt column, appreciably alter accretionary or fault processes, and have identifiable surface expressions. Further empirical assessment of bathymetry is thus useful for purposes of confirming patterns and constraining processes. Here we report on spectral analyses of bathymetry recently acquired from the Juan de Fuca ridge between 44°30'N and 45°15'N during the SeaVOICE expedition. Multibeam swath sonar data were acquired with an EM122 sonar insonfiying seafloor to crustal ages of ˜2 ma with 35 m spatial resolution. We examine (1.) the statistical significance of concentrations of bathymetric variability at the 100 ky, 41 ky, and 23 ky periods characteristic of late-Pleistocene sea level variability; (2.) whether sea level responses are primarily at 41 ky periods in crust accreted during the early Pleistocene, when global sea level variations were primarily at this period; and (3.) if sea level responses are superimposed on bathymetry variations or, instead, align with fault features. We also note that Juan de Fuca's proximity to the Cordilleran Ice Sheet implies that regional

    Full Text Available Don Juan is a myth about a seducer, a man with many love adventures, a women’s heat conqueror, and many other predicates. Don Juan as a myth is well-known world wide over, appearing in about 50 writings such as novels, plays, operas. But a French writer Eric-Emannuel Schmitt proposes a new figure of Don Juan in his play La Nuit de Valognes (Night in Valognes: the seducer is judged by five victims and convicted to marry one of his victims in order to stop his adventures. Surprisingly, Don Juan accepts this verdict without conditions. This sudden change becomes the theme of the play: the demythification of Don Juan. A flash back scene shows the beginning of this change and the interpretations that might arise from here. One possible interpretation is proposed and discussed in this paper: Don Juan found the way to a purer love, which is the union with God, and decides to begin his journey. This play can thus be categorised as a sufi text.

    This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities. The social security sector or Obras Sociales (OS) covers all workers of the formal economy and their families. Most OS operate through contracts with private providers and are financed with payroll contributions of employers and employees. Finally, the private sector includes all those private providers offering services to individuals, OS beneficiaries and all those with private health insurance.This sector also includes private insurance agencies called Prepaid Medicine Enterprises, financed mostly through premiums paid by families and/or employers.This paper also discusses some of the recent innovations implemented in Argentina, including the program Remediar.

El sector público está integrado por los ministerios nacional y provincial, y la red de hospitales y centros de salud públicos que prestan atención gratuita a toda persona que lo demande, fundamentalmente a personas sin seguridad social y sin capacidad de pago. Se financia con recursos fiscales y recibe pagos ocasionales de parte del sistema de seguridad social cuando atiende a sus afiliados. El sector del seguro social obligatorio está organizado en torno a las Obras Sociales (OS, que aseguran y prestan servicios a los trabajadores y sus familias. La mayoría de las OS operan a través de contratos con prestadores privados y se financian con contribuciones de los trabajadores y patronales. El sector privado está conformado por profesionales de la salud y establecimientos que atienden a demandantes individuales, a los beneficiarios de las OS y de los seguros privados. Este sector también incluye entidades de seguro voluntario llamadas Empresas de Medicina Prepaga que se financian sobre todo con primas que pagan las familias y/o las empresas.

    Full Text Available Dissemination of Braille as an alternative means of visual communication has been a key factor in the integration of blind people. The Braille system was introduced in Argentina by teaching Juan Lorenzo González.This article aims to contribute to the knowledge of the unknown blind master. Although he remained in Spain overshadowed by other teachers, his altruistic personality led him to settle in the city of Buenos Aires, where he developed his greatest educational work. On 1 March 1887, the official of the Sociedad de Beneficencia of Buenos Aires proposed to him, a newcomer to this city, as a teacher of the blind people in the Asilo de Huérfanos. The proposal was accepted with a quick response and a few months after his appointment, he began his task. It was then when the institutional and professional care of the blind people in Argentina began; until then had only the blind received material support and charitable shelter. This study was approached from a historical perspective, has been based on archival sources,historical and current newspapers and publications, mainly Argentina. In this research reveal meaningful data that allow some of the unknowns about the biography of this remarkable personality.La difusión del sistema Braille como un medio de comunicación alternativo al visual ha supuesto un factor determinante en la integración de las personas ciegas.

  15. From surfaces to magnetic properties: special section dedicated to Juan Rojo

    2013-12-01

    Surface physics and magnetism, in particular the connection between surface defects, reduced dimensionality or size, crystal structure, electronic density of states and the mechanical and magnetic properties of solids, were always at the core of Juan Rojo's scientific interest and output. Both fields seem to meet at the nanoscale, a privileged playing field which is ideal for testing theoretical concepts, exploring new physics or probing a wealth of new, stunning and unheard-of applications. Upon reducing size or dimensionality, either in bulk systems or in thin films, surfaces and surface effects are telling. Thus, for instance, an ultra-thin coating can make nanoparticles of non-magnetic materials exhibit magnetic behaviour; or atomic steps can modify the local mechanical properties of a metallic single crystal. In this special section there are eight invited papers by disciples and close collaborators of Juan Rojo, that cover an ample spectrum of the above mentioned topics. The first paper, by Palacio et al, investigates the temperature and oxygen partial pressure conditions for FeO mono- and bi-layer growth on Ru(0001). The following paper, by Cortés-Gil et al, reports on the dramatic change in the electric resistivity of the manganite perovskite (La0.5Ca0.5)z MnO3 as a function of Ca content, an effect related to the removal of a charge-ordered state and a magnetic transition. Baeza et al study biomaterials for bone cancer treatment and skeletal reinforcing, as well as targeted magnetic nanoparticles used for intracell hyperthermia in cancer therapies. In the following paper, Marcano et al, assisted by a multi-technique approach, revisit the extraordinarily rich magnetic phase diagram of the Kondo system CeNi1- x Cux down to 100 mK temperatures. The magnetic field dependence of the martensitic transition temperature of the meta-magnetic shape memory alloy Ni50Mn34.5In15.5 in a crystalline and amorphous phase, in fields up to 13 T, is the subject of the paper

    Soybean biomass for biodiesel, produced in Argentina amongst other places, is considered by some to reduce greenhouse gas emissions and mitigate climate change when compared with fossil fuel. To ensure that the production of biofuels is ‘sustainable', EU institutions and national governments...... are currently designing certification schemes for the sustainable production of biomass. This paper questions the validity of proposed environmental standards, using the production of Argentine soybean as a case study. The production of soybean production is associated with profound environmental impacts...... generates emissions of N2O.

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

    This work presents a new age framework for the main Bashkirian glacio-eustatic transgression in Argentina, including the first absolute age for the Jejenes Formation, San Juan Province, based on radiometric dating of a crystal-rich tuff, supported by palynological and palaeofloristic studies, and presented within a revised palaeogeographic setting. The Jejenes Formation represents the glacial to postglacial fill of the Quebrada Grande palaeofjord carved in the Eastern Precordillera. The succession has been subdivided into five stages, the youngest of which suggests a previously unrecognised glacial event for this locality. Six productive levels for palynology were found within proglacial strata, and in the base and top of the succeeding interglacial stage. Palynoassemblages are characterized by poorly preserved trilete spores and monosaccate pollen grains along with a large amount of terrestrial phytoclasts. Main species indicating the Raistrickia densa-Convolutispora muriornata SubZone (DMa SZ) are Vallatisporites ciliaris, Cristatisporites rollerii, C. stellatus, C. chacoparanensis, C. inconstans and monosaccates such as Circumplicatipollis plicatus. This DMa SZ is estimated as Serpukhovian/Bashkirian and characterizes the glacial-related Guandacol Formation and equivalents units of the western Paganzo Basin. A tuffaceous level in the proglacial unit, bearing platyspermic seeds, plant remains and palynomorphs, yielded first-cycle volcanic zircons that were analysed by SHRIMP. An absolute age of 321.3 ± 5.3 Ma confirms a Bashkirian age for the main postglacial transgression in the Paganzo Basin, and offers a novel calibration for the palynoassemblages of DMa SZ that occurs elsewhere in Western Argentina.

    Full Text Available Este trabajo desarrollará la idea de que la escritura crítica, metaficcional y autorreferente de Juan Emar -desde las "Notas de Arte" (1924-1927 hasta el proyecto monumental de Umbral (1940-1964- puede comprenderse, por un lado, como espacio de resonancia de una estructura cinemática de percepción que se perfila como fundamental experiencia de vida durante la primera mitad del siglo XX. Por otro lado, sus textos, en diferentes niveles enunciativos, son parte de la conceptualización de esta misma experiencia. En este sentido, lo cinemático es un imaginario multiforme de la percepción del movimiento que culmina en el cine de vanguardia de los años veinte; mientras que lo cinematográfico se relaciona con el fenómeno del cine propiamente tal, sus posibilidades tecnológicas y los elementos que lo convierten en espectáculo. Estos polos tensionan la escritura de Emar en el nivel referencial, reflexivo, y estético-formal.

    Full Text Available Este ensayo discute la temporalidad en la narrativa de Juan Rulfo a través de los recursos que utiliza para exponer las tramas de sus personajes. La temporalidad del fantasma Rulfiano es determinante en los enigmas que devienen del campo simbólico en el que se desarrolla la obra. Estos personajes plantean fronteras móviles en su actuación pues la muerte les da un carácter ilimitado de acción perdiendo la secuencia histórica del presente-pasado-futuro. Asimismo se plantean algunas relaciones hipotéticas entre el autor y su obra señalando la polisemia resultante del uso de la metáfora. La estructura de la obra y la suspensión de las tramas hacen del lector un co-autor. A través del ensueño Rulfo inventa una manera de leer y escribir la muerte a través de su fantasmagoría.

La pregunta que desencadenó este trabajo buscó indagar el momento y las circunstancias en que García incorporó para sí la matriz del marxismo para pensar los problemas de salud. De esta manera, siguiendo los lineamientos metodológicos propuestos por Pierre Bourdieu, utilizamos la noción de "trayectoria de vida" para reconstruir un recorrido vital que se bifurca en varias rutas, de su Necochea natal a la ciudad de La Plata, desde allí hasta Santiago de Chile y, finalmente, sus innumerables viajes desde Washington hacia gran parte de América Latina. Para ello, realizamos entrevistas semiestructuradas con informantes clave, familiares, amigos y colegas de Argentina, Brasil, Ecuador y Cuba. Asimismo, analizamos los títulos de su biblioteca personal, donada a la fundación internacional que lleva su nombre, y documentos de distintos archivos particulares.

    2014-01-01

    Hurricane Juan provides an excellent opportunity to probe into the detailed wave spectral patterns and spectral parameters of a hurricane system, with enough wave spectral observations around Juan’s track in the deep ocean and shallow coastal water. In this study, Hurricane Juan and wave observation stations around Juan’s track are introduced. Variations of wave composition are discussed and analyzed based on time series of one-dimensional frequency spectra, as well as wave steepness around Juan’s track:before, dur-ing, and after Juan’s passing. Wave spectral involvement is studied based on the observed one-dimensional spectra and two-dimensional spectra during the hurricane. The standardization method of the observed wave spectra during Hurricane Juan is discussed, and the standardized spectra show relatively conservative behavior, in spite of the huge variation in wave spectral energy, spectral peak, and peak frequency during this hurricane. Spectral widths’ variation during Hurricane Juan are calculated and analyzed. A two-layer nesting WW3 model simulation is applied to simulate the one-dimensional and two-dimensional wave spectra, in order to examine WW3’s ability in simulating detailed wave structure during Hurricane Juan.

A análise desses documentos contradiz uma faceta generalizante presente na fortuna crítica do autor, que o descreve como homem solitário e frio. Nos textos aqui estudados, Onetti manifesta seu carinho e admiração por Payró. Da mesma forma, as cartas oferecem dados que contestam a imagem do Onetti descompromissado, já que ele demonstra preocupação com os rumos da política de seu país. A correspondência também revela inseguranças e vaidades que a figura pública fazia questão de manter escondidas. Nesse sentido, este trabalho sugere que investigações a partir de documentos pessoais de escritores podem ampliar fortemente a interpretação de sua obra e às vezes se opor a juízos estabelecidos pelos críticos que não tiveram acesso a esse material.

    Full Text Available Abstract Background In contrast to DNA-mediated transposable elements (TEs, retrotransposons, particularly non-long terminal repeat retrotransposons (non-LTRs, are generally considered to have a much lower propensity towards horizontal transfer. Detailed studies on site-specific non-LTR families have demonstrated strict vertical transmission. More studies are needed with non-site-specific non-LTR families to determine whether strict vertical transmission is a phenomenon related to site specificity or a more general characteristic of all non-LTRs. Juan is a Jockey clade non-LTR retrotransposon first discovered in mosquitoes that is widely distributed in the mosquito family Culicidae. Being a non-site specific non-LTR, Juan offers an opportunity to further investigate the hypothesis that non-LTRs are genomic elements that are primarily vertically transmitted. Results Systematic analysis of the ~1.3 Gbp Aedes aegypti (Ae. aegypti genome sequence suggests that Juan-A is the only Juan-type non-LTR in Aedes aegypti. Juan-A is highly reiterated and comprises approximately 3% of the genome. Using minimum cutoffs of 90% length and 70% nucleotide (nt identity, 663 copies were found by BLAST using the published Juan-A sequence as the query. All 663 copies are at least 95% identical to Juan-A, while 378 of these copies are 99% identical to Juan-A, indicating that the Juan-A family has been transposing recently in evolutionary history. Using the 0.34 Kb 5' UTR as the query, over 2000 copies were identified that may contain internal promoters, leading to questions on the genomic impact of Juan-A.

    The Navajo Nation is America's largest native American tribe by population and acreage, and is blessed with large tracks of good coal deposits. BHP Billiton's New Mexico Coal Co. is the largest in the Navajo regeneration area. The holdings comprise the San Juan underground mine, the La Plata surface mine, now in reclamation, and the expanding Navajo surface mine. The article recounts the recent history of the mines. It stresses the emphasis on sensitivity to and helping to sustain tribal culture, and also on safety. San Juan's longwall system is unique to the nation. It started up as an automated system from the outset. Problems caused by hydrogen sulfide are being tackled. San Juan has a bleederless ventilation system to minimise the risk of spontaneous combustion of methane and the atmospheric conditions in the mine are heavily monitored, especially within the gob areas. 3 photos.

  16. Microbiological characterization of post-eruption "snowblower" vents at Axial Seamount, Juan de Fuca Ridge.

    Microbial processes within the subseafloor can be examined during the ephemeral and uncommonly observed phenomena known as snowblower venting. Snowblowers are characterized by the large quantity of white floc that is expelled from the seafloor following mid-ocean ridge eruptions. During these eruptions, rapidly cooling lava entrains seawater and hydrothermal fluids enriched in geochemical reactants, creating a natural bioreactor that supports a subseafloor microbial "bloom." Previous studies hypothesized that the eruption-associated floc was made by sulfide-oxidizing bacteria; however, the microbes involved were never identified. Here we present the first molecular analysis combined with microscopy of microbial communities in snowblower vents from samples collected shortly after the 2011 eruption at Axial Seamount, an active volcano on the Juan de Fuca Ridge. We obtained fluid samples and white flocculent material from active snowblower vents as well as orange flocculent material found on top of newly formed lava flows. Both flocculent types revealed diverse cell types and particulates when examined by phase contrast and scanning electron microscopy (SEM). Distinct archaeal and bacterial communities were detected in each sample type through Illumina tag sequencing of 16S rRNA genes and through sequencing of the sulfide oxidation gene, soxB. In fluids and white floc, the dominant bacteria were sulfur-oxidizing Epsilonproteobacteria and the dominant archaea were thermophilic Methanococcales. In contrast, the dominant organisms in the orange floc were Gammaproteobacteria and Thaumarchaeota Marine Group I. In all samples, bacteria greatly outnumbered archaea. The presence of anaerobic methanogens and microaerobic Epsilonproteobacteria in snowblower communities provides evidence that these blooms are seeded by subseafloor microbes, rather than from microbes in bottom seawater. These eruptive events thus provide a unique opportunity to observe subseafloor microbial

    Guardo en mi biblioteca tres libros de tipo biográfico con dedicatoria del autor, el académico Juan Pablo Llinás Cuentas (1924-2011. Investigó este culto colega en los años ochenta sobre la vida de algunos de nuestros prohombres, como Atanasio Girardot, José Hilario López y José Celestino Mutis, siendo este último libro comentado en mi columna semanal de otrora, la del diario barranquillense El Heraldo. Como todos los que llevan los genes Llinás, sus raíces estaban en Sabanalarga, de donde  era también el ilustre profesor y académico César Augusto Pantoja. Me honró Llinás con su amistad (al igual que su hijo Adolfo, el ortopedista. Edgardo Coronado –escritor e historiador de la segunda ciudad del Atlántico (por tamaño, pero la primera en antigüedad y en abolengos– dijo de él que “su experiencia de 30 años como profesor le dio paciencia, entendimiento y sabiduría, lo que le permitió escribir diez libros sobre temas de historia, ética, medicina y filosofía, que fueron su satisfacción y el camino para encontrarse y encontrar a los demás”. 

    Mi contacto personal con Llinás fue precisamente en la década de los ochenta, cuando en su condición de Coordinador del Programa de Ciencias Básicas de la recién fundada Universidad del Norte, me llamó en varias ocasiones para que dictara mis cursos de fisiología endocrina en este centro académico de excelencia, faro de ciencia y de cultura. Su fuerte eran –por supuesto– las humanidades. De vocablo educado y gentiles maneras, Juan Pablo sabía de medicina, de historia, de filosofía, de artes plásticas y de poesía. En un grupo de amigos de las letras y de las artes en Barranquilla, organizaba reuniones con amigos personales como el poeta Eduardo Carranza, o divagaba sobre el significado imaginario de esculturas enigmáticas del maestro Edgar Negret.

    Full Text Available Meteorological factors influence dengue virus ecology by modulating vector mosquito population dynamics, viral replication, and transmission. Dynamic modeling techniques can be used to examine how interactions among meteorological variables, vectors and the dengue virus influence transmission. We developed a dengue fever simulation model by coupling a dynamic simulation model for Aedes aegypti, the primary mosquito vector for dengue, with a basic epidemiological Susceptible-Exposed-Infectious-Recovered (SEIR model. Employing a Monte Carlo approach, we simulated dengue transmission during the period of 2010-2013 in San Juan, PR, where dengue fever is endemic. The results of 9600 simulations using varied model parameters were evaluated by statistical comparison (r2 with surveillance data of dengue cases reported to the Centers for Disease Control and Prevention. To identify the most influential parameters associated with dengue virus transmission for each period the top 1% of best-fit model simulations were retained and compared. Using the top simulations, dengue cases were simulated well for 2010 (r2 = 0.90, p = 0.03, 2011 (r2 = 0.83, p = 0.05, and 2012 (r2 = 0.94, p = 0.01; however, simulations were weaker for 2013 (r2 = 0.25, p = 0.25 and the entire four-year period (r2 = 0.44, p = 0.002. Analysis of parameter values from retained simulations revealed that rain dependent container habitats were more prevalent in best-fitting simulations during the wetter 2010 and 2011 years, while human managed (i.e. manually filled container habitats were more prevalent in best-fitting simulations during the drier 2012 and 2013 years. The simulations further indicate that rainfall strongly modulates the timing of dengue (e.g., epidemics occurred earlier during rainy years while temperature modulates the annual number of dengue fever cases. Our results suggest that meteorological factors have a time-variable influence on dengue transmission relative to other

    Objective The metabolic syndrome is associated with a high risk of diabetes and cardiovascular disease, and Hispanics in the United States have higher rates than do other ethnic groups. We assessed the prevalence of the metabolic syndrome and its individual components in Puerto Rican adults. Methods We conducted a cross-sectional study that used a probability cluster design to select a sample of households of the San Juan metropolitan area from 2005 through 2007. A total of 859 persons aged 21–79 years completed a face-to-face interview, blood pressure and waist circumference measurements, and blood sampling. Our primary outcome measure was metabolic syndrome as defined by the updated NCEP-ATP criteria. Results Prevalence of the metabolic syndrome was 43.3%; 45.3% for men and 42.2% for women (P>.05). Prevalence significantly rose with age, from 12.8% among participants aged 21–29 years to 58.2% for participants aged 70–79 years (P<.001). Corresponding increases in the prevalence of the metabolic syndrome in both men and women were also observed; the prevalence peaked in men aged 50–59 years (62.6%) and in women aged 70–79 years (65.2%). Elevated glucose (49.8%) and abdominal obesity (49.0%) were the most common components of the metabolic syndrome, followed by elevated blood pressure (46.1%), reduced high-density lipoprotein cholesterol (46.0%), and elevated triglycerides (31.3%). Substantial variations were found between men and women in the prevalence of individual components. Conclusions Puerto Ricans have a high prevalence of the metabolic syndrome. This health disparity has implications for diabetes and cardiovascular prevention programs. PMID:19157247

    2007-10-01

    We use data from the Chile Argentina Geophysical Experiment (CHARGE) broad-band seismic deployment to refine past observations of the geometry and deformation within the subducting slab in the South American subduction zone between 30°S and 36°S. This region contains a zone of flat slab subduction where the subducting Nazca Plate flattens at a depth of ~100 km and extends ~300 km eastward before continuing its descent into the mantle. We use a grid-search multiple-event earthquake relocation technique to relocate 1098 events within the subducting slab and generate contours of the Wadati-Benioff zone. These contours reflect slab geometries from previous studies of intermediate-depth seismicity in this region with some small but important deviations. Our hypocentres indicate that the shallowest portion of the flat slab is associated with the inferred location of the subducting Juan Fernández Ridge at 31°S and that the slab deepens both to the south and the north of this region. We have also determined first motion focal mechanisms for ~180 of the slab earthquakes. The subhorizontal T-axis solutions for these events are almost entirely consistent with a slab pull interpretation, especially when compared to our newly inferred slab geometry. Deviations of T-axes from the direction of slab dip may be explained with a gap within the subducting slab below 150 km in the vicinity of the transition from flat to normal subducting geometry around 33°S.

    A high-resolution superficial geophysical study was carried out in an area of the retroarc region of the Andes mountains, located in the southwest of San Juan Province (31°45‧ S, 68°50‧ W), Central Precordillera of Argentina. The main objectives of this study were to confirm the presence of blind neotectonic structures and characterize them by observing variations in magnetic susceptibility, density and p-wave velocities. Geological evidence demonstrates the existence of a neotectonic fault scarps affecting Quaternary alluvial deposits in eastern piedmont of de Las Osamentas range, in addition to direct observation of the cinematic of this feature in several natural exposures. The Maradona valley is characterized by the imbricated eastern-vergence Maradona Fault System that uplifts Neogene sedimentary rocks (Albarracín Formation) over Quaternary (Late Pleistocene-Holocene) alluvial deposits. The combined application of different geophysical methods has allowed the characterization of a blind fault geometry also identified on a natural exposure. The magnetic data added to the gravimetric model, and its integration with a seismic profile clearly shows the existence of an anomalous zone, interpreted as uplifted blocks of Miocene sedimentary rocks of Formation Albarracín displaced over Quaternary deposits. The application and development of different geophysical methods, together with geological studies allow to significantly improving the knowledge of an area affected by Quaternary tectonic activity. Finally, this multidisciplinary study, applied in active blind structures is very relevant for future seismic hazard analysis on areas located very close to populated centers.

  5. El anti-don Juan de María de Zayas

    2014-12-01

    Full Text Available All critics agree on considering that María de Zayas writes inspired by the anger that she feels for the women condition. Both in her prose and in the only play we know, La traición en la amistad, Zayas censures with irony and wit the don-Juan type who deceives women leaving them without honour. She does it elaborating an intertextual relationship with El burlador de Sevilla. Specifically, in the play she uses three characters: Liseo, who deceives three women, Fenisa, who is a don-Juan female even more exaggerated than Liseo, and don Juan, the less donjuanesco of all. As a matter of fact, Zayas creates an anti-don Juan similar to the one that Ventura de la Vega will realize in the XIX century with his play El hombre de mundo, a parody of Zorrilla’s Don Juan Tenorio; nevertheless it has a clear ethical purpose: to warn women of his age in order to avoid men’s abuses.Los críticos concuerdan en que María de Zayas escribe inspirada por la cólera que le provoca la condición femenina coetánea. Tanto en sus novelas como en la única comedia conservada, La traición en la amistad, Zayas censura con sutil ironía al tipo donjuanesco que se burla de las mujeres dejándolas sin honor, y lo hace entablando un complejo e ingenioso diálogo intertextual con El burlador de Sevilla. De forma especial, en la pieza lo hace a través de tres figuras: Liseo, que engaña a tres mujeres, Fenisa, un don Juan mujer aún más hiperbólico que Liseo, y don Juan, el menos donjuanesco de todos. En definitiva, crea un anti-don Juan parecido al que Ventura de la Vega realizará en el siglo XIX con El hombre de mundo, parodia del Tenorio de Zorrilla, pero con una clara intencionalidad ética: la de aleccionar a las mujeres de su época para que aprendan a esquivar a los hombres que abusan de ellas.

    The article describes the authors and works which were quoted by the Franciscan Juan Gil de Zamora in his Historia naturalis, a scientific encyclopaedia written between c. 1275 and before 1296, probably in the Franciscan monastery of Zamora (Kingdom of Castille). Juan Gil made wide use of the Avicenna's Canon, Gilbertus de Aquila (Anglicus)'s Compendium medicine, and Salernitan medical literature. His work contributed to the diffusion of these medical authors and works throughout the Christian intellectual milieu of late medieval Castille. This diffusion was not without problems.

    The authors of the present selection of Latin American Psychiatry texts were characterized by a common deep humanistic attitude. These prolific writers were able to establish or extend the scope of the discipline in which they chose to act, questioning the establishment of rigid boundaries within the framework of a rigorous epistemological reflection. Thus the systematizing spirit of Jose Ingenieros' in the context of positivist evolutionism, resulted in the act of founding a discipline that integrated the biological and the social. In the case of Guillermo Vidal his conception of mental health went beyond the biomedical to consider psychotherapies as an emotional commitment, continence and empathic understanding; with regard to César Cabral his formation and extensive clinical practice resulted in a work defined by the inquiring into the theoretical concepts underlying Psychiatry and Clinical Psychology. This brief selection does not exhaust the issues or the level of ideas and discussions of Psychiatry in Argentina, but constitutes a textual corpus representative of a disciplinary conception understood as scientific and humanistic endeavor.

    The aim of this article is to present and analyse four dietary prescriptions from the 16th century prepared for Juan Rena, a cleric of Venetian origin, and his servant Juan de Alarcón, which are kept at the Archivo General de Navarra. These documents demonstrate the interest of the patients and physicians in dietetics, understood as a group of health and hygienic measures based on the Galenic res naturales and res non naturales. These four prescriptions are closely related to the ad personam or consilia health regimens, which represent a genre of medical literature whose significance in Renaissance Spain has received little attention. The cases studied reveal the high esteem in which the elites held the possession of therapeutic resources adapted to their individual needs, which were compiled and copied for personal use.

    Acute toxicity tests were conducted with larval Colorado squawfish (Ptychocheilus lucius) and razorback sucker (Xyrauchen texanus) in a constituted water quality simulating the San Juan River near Shiprock, New Mexico. Tests were conducted with arsenate, copper, selenate, selenite, zinc, and five mixtures of seven to nine inorganics simulating environmental mixtures reported for sites along the San Juan River (Ojo Amarillo Canyon, Gallegos Canyon, Hogback East Drain, Mancos River, and McElmo Creek). Razorback suckers were significantly more sensitive to arsenate, selenate, selenite, Hogback East Drain mixture, and Ojo Amarillo Canyon mixture than were Colorado squawfish. The Gallegos Canyon mixture had greater than additive, i.e., synergistic, toxicity to both species, the Ojo Amarillo Canyon mixture had less than additive, i.e., antagonistic, toxicity to both species, and the Mancos River and McElmo Creek mixtures had additive toxicity to both species. The Hogback East Drain mixture had additive toxicity to Colorado squawfish, but synergistic toxicity to razorback suckers. The major toxic component in the five mixtures was copper. Comparison of 96-hour LC50 values with a limited number of environmental water concentrations from the San Juan River revealed high hazard ratios for copper and all five environmental mixtures. The high hazard ratios suggest inorganic contaminants could adversely affect larval Colorado squawfish and razorback suckers in the San Juan River at sites receiving elevated inorganics.

    Nova Scotia Power Inc. (NSPI) has responded to several recommendations made by an independent consultant regarding its emergency response to Hurricane Juan which hit the Halifax Regional Municipality on September 28, 2003. NSPI is in agreement with most of the recommendations and is enhancing its preparedness for use in disaster scenarios similar to Hurricane Juan. Several recommendations have already been implemented by the power company including, improvements to call centre technology and processes, and better coordination with the electricity market operator and municipal responders. Lessons learned from Hurricane Juan were applied during a snow storm in February 2004, particularly in terms of communications. NSPI strongly disagrees with the consultant's recommendation to bring in hundreds of line crews from outside the region in advance of a major storm. NSPI argues that doing so, would have tripled or quadrupled Hurricane Juan costs to $40 or $50 million with little or no improvement on restoration times. Nova Scotia Power Inc. is a wholly-owned subsidiary of Emera (EMA-TSX). The utility provides more than 97 per cent of electric generation, transmission, and distribution to more than 460,000 customers across Nova Scotia. NSPI is committed to supporting Nova Scotian communities by providing safe, reliable power.

    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.

    Over 400 million barrels (64 million m{sup 3}) of oil have been produced from the shallow-shelf carbonate reservoirs in the Pennsylvanian (Desmoinesian) Paradox Formation in the Paradox Basin, Utah and Colorado. With the exception of the giant Greater Aneth field, the other 100 plus oil fields in the basin typically contain 2 to 10 million barrels (0.3-1.6 million m{sup 3}) of original oil in place. Most of these fields are characterized by high initial production rates followed by a very short productive life (primary), and hence premature abandonment. Only 15 to 25 percent of the original oil in place is recoverable during primary production from conventional vertical wells. An extensive and successful horizontal drilling program has been conducted in the giant Greater Aneth field. However, to date, only two horizontal wells have been drilled in small Ismay and Desert Creek fields. The results from these wells were disappointing due to poor understanding of the carbonate facies and diagenetic fabrics that create reservoir heterogeneity. These small fields, and similar fields in the basin, are at high risk of premature abandonment. At least 200 million barrels (31.8 million m{sup 3}) of oil will be left behind in these small fields because current development practices leave compartments of the heterogeneous reservoirs undrained. Through proper geological evaluation of the reservoirs, production may be increased by 20 to 50 percent through the drilling of low-cost single or multilateral horizontal legs from existing vertical development wells. In addition, horizontal drilling from existing wells minimizes surface disturbances and costs for field development, particularly in the environmentally sensitive areas of southeastern Utah and southwestern Colorado.

    We obtain earthquake locations and a detailed three-dimensional model of the subduction zone velocity structure in west-central Argentina by applying a regional-scale double-difference tomography algorithm to earthquake data recorded by the SIEMBRA (2007-2009) and ESP (2008-2010) broadband seismic networks. In this region, the flat subduction of the Nazca Plate including the Juan Fernandez Ridge is spatially correlated in the overriding South America Plate with a gap in the arc volcanism and the thick-skinned, basement-cored uplifts of the Sierras Pampeanas. Our model shows the subducting Nazca Plate as a mostly continuous band of increased (2-6%) P- and S- wave velocities (Vp and Vs). The lithospheric mantle of the South America Plate appears to be heterogeneous but mostly characterized by Vp of 8.0-8.2 km/s, Vs of 4.5-4.7 km/s, and Vp/Vs ratio of 1.75-1.78, which is consistent with either a depleted lherzolite or harzburgite. We observe a region of higher Vp/Vs ratio (1.78-1.80) that we correlated with up to 10% hydration of mantle peridotites above the flat slab. In addition, we observe localized regions of lower Vp/Vs ratio (1.71-1.73) in the mantle above the westernmost part of the flat slab, suggesting orthopyroxene enrichment. Our velocity observations are consistent with the presence of Paleozoic carbonate rocks in the Precordillera and the differences in composition for the Sierras Pampeanas basement: a more mafic composition for Cuyania Terrane in the west and a more felsic composition for the Pampia Terrane in the east. Additionally, we present new contours for the Wadati-Benioff Zone (WBZ). The top of the WBZ of the Nazca Plate is nearly flat at ~100 km depth approximately within the region of latitude 28-32°S and longitude 70-68.5°W. We determined that WBZ is a single layer of seismicity with thickness of 10-15 km, which may correspond to the dehydration of the subducting oceanic mantle. We found that the flat slab region is wider (~240 km) than the

    Here we examine Fe speciation within Fe-encrusted biofilms formed during 2-month seafloor incubations of sulfide mineral assemblages at the Main Endeavor Segment of the Juan de Fuca Ridge. The biofilms were distributed heterogeneously across the surface of the incubated sulfide and composed primarily of particles with a twisted stalk morphology resembling those produced by some aerobic Fe-oxidizing microorganisms. Our objectives were to determine the form of biofilm-associated Fe, and identify the sulfide minerals associated with microbial growth. We used micro-focused synchrotron-radiation X-ray fluorescence mapping (mu XRF), X-ray absorption spectroscopy (mu EXAFS), and X-ray diffraction (mu XRD) in conjunction with focused ion beam (FIB) sectioning, and highresolution transmission electron microscopy (HRTEM). The chemical and mineralogical composition of an Fe-encrusted biofilm was queried at different spatial scales, and the spatial relationship between primary sulfide and secondary oxyhydroxide minerals was resolved. The Fe-encrusted biofilms formed preferentially at pyrrhotite-rich (Fe1-xS, 0<_ x<_ 0.2) regions of the incubated chimney sulfide. At the nanometer spatial scale, particles within the biofilm exhibiting lattice fringing and diffraction patterns consistent with 2-line ferrihydrite were identified infrequently. At the micron spatial scale, Fe mu EXAFS spectroscopy and mu XRD measurements indicate that the dominant form of biofilm Fe is a short-range ordered Fe oxyhydroxide characterized by pervasive edge-sharing Fe-O6 octahedral linkages. Double corner-sharing Fe-O6 linkages, which are common to Fe oxyhydroxide mineral structures of 2-line ferrihydrite, 6-line ferrihydrite, and goethite, were not detected in the biogenic iron oxyhydroxide (BIO). The suspended development of the BIO mineral structure is consistent with Fe(III) hydrolysis and polymerization in the presence of high concentrations of Fe-complexing ligands. We hypothesize that

El límite entre los dos sistemas morfoestructurales, uno la Precordillera Oriental y el otro el Sistema Pampeano Occidental ha sido establecido en trabajos anteriores, a lo largo del sistema de fallamiento de Tulum, que cruza a la depresión diagonalmente en dirección NNE. No obstante la disponibilidad de nueva información de sondeos eléctricos verticales y de algunas perforaciones para búsqueda de agua subterránea, efectuados al sur y al oeste del cerro Valdivia, permite señalar que hacia el suroeste de este núcleo de basamento metamórfico limitado en ambos flancos por fallas, el límite Sistema Pampeano y Precordillera se aproxima al cordón montañoso de sierra Chica de Zonda, continuando al sur en el cerro Salinas. De allí al SSO existen, en superficie, indicaciones de que el sistema de fallamiento continúa hasta el Montecito, donde el sistema pampeano de fallas queda interrumpido por la gran falla con actividad cuaternaria que sirve de límite oriental a la sierra de Las Peñas. El contacto entre ambos sistemas forma el extremo sur de la Precordillera Oriental en subsuelo. Este conocimiento estructural permite no solo ser aplicado a la prospección de agua sino también a la de hidrocarburos en la región.

    In Argentina, vaccines for immuno-preventable diseases are regulated by the national regulatory agency, the Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (the National Administration of Drugs, Food and Medical Devices, or ANMAT) created in 1992 to ensure efficacy and safety of drugs, food and medical devices available in the country, according to Law 16,463 and Decree 150/92. ANMAT has licensed 84 out of 157 vaccines registered in Argentina. Since 1994, ANMAT evaluated, approved and inspected 20 clinical trials with vaccines (1.8% of the 1062 trials approved by the agency since that time). The National System of Pharmaco-vigilance has received 318 communications of eventual adverse post-vaccination events (0.3% of the total). In addition, ANMAT provides support to the National Immunisation Programme. The current procedure is to follow international guidelines in the field, to be prepared for new, rapidly changing scenarios.

    Rhinella spinulosa is an anuran toad species distributed latitudinal and altitudinal (1200-5000m) from Peru to Argentina, inhabiting mountain valleys in the Andes. Considering the broad range of habitats where they live, it is important to understand the thermal physiological mechanisms, thermal tolerances and physiological adaptations for surviving in rigorous environments. We investigated the thermal parameters (field body temperature, selected body temperature, locomotor performance in field and laboratory conditions, and thermal extremes) during diurnal activity for a population of juvenile, post-metamorphosed toads (Rhinella spinulosa) from the Monte Desert of San Juan, Argentina. Post-metamorphic toads are active from approximately 1100-1900 (in contrast to nocturnal adult toads). Our findings show that these toads have a wide thermal tolerance range, ranging from a critical thermal maximum of 36.9°C to crystallization temperatures below 0°C. During their active period, toads always showed suboptimal thermal conditions for locomotion. Despite the suboptimal condition for the locomotion, diurnal activity is likely to confer thermal advantages, allowing them to search for food and increase digestion and growth rates. We also found that the toads are capable of super-cooling, which prevents mortality from freezing when the environmental temperatures drop below 0°C. The environmental temperatures are below zero at night, when toads are inactive and take refuge under rocks. In summary, this toad population demonstrates high thermal plasticity, as shown by a relatively high level of activity sustained over a wide range of ambient temperature (~35°C). These thermal adaptations allow this species of juvenile toads to inhabit a wide range of altitudes and latitudes.

    Klein had been asked to contribute an article to the birthday number of the International Journal for Jones. The author outlines how she hurriedly wrote a text about Don Juan which, however, was rejected by the editor. Essential parts of it are presented in German translation. The manuscript is discussed in the context of Klein's published work as well as of the relevant contemporary literature. In Klein's view, Don Juan's genitality is determined by oral impulses and fears. By his manic acting out he attempts to ward off a depressive break-down. The paper ends with some reflections about why Klein--ontrary to her intention--failed to revise her manuscript for later publication.

  12. An unpublished Roman inscription from Cortinal de San Juan (Salvatierra de Tormes, Salamanca

    Full Text Available In this paper is presented a slate with a Roman inscription found in archaeological survey work conducted in September 2014 in Cortinal de San Juan (Salvatierra de Tormes. This site has been, since its discovery and cataloging, a place of reference for the late Roman and Visigothic settlement Southeast Salamanca. Currently, this archaeological site is partially flooded by the Santa Teresa swamp. The main feature of this Roman inscription is that the slate support isn’t usual in the chronology proposed for such inscription. Despite the fact that other archaeological materials of Cortinal de San Juan are associated with late Roman or Visigothic chronocultural context, the type of capital letter, the large size of the letter, and the parallels established with other finds of similar chronology suggest this inscription could be part of a Roman anthroponym as the most successful interpretive hypothesis.

  14. Acute Intermittent Porphyria in Argentina: An Update

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available 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.

  15. Argentina: Nuclear power development and Atucha 2

    Energy Technology Data Exchange (ETDEWEB)

    Nogarin, Mauro

    2015-08-15

    In 2014, nuclear energy generated about 5,257 GWh of electricity or a total share of 4.05 % of the total electrical energy of about 129,747.63 GWh kWh produced in Argentina and there has been a trend for this production to increase. Argentina currently has a nuclear production capacity of 1,010 megawatts of electrical energy. However, when the Atucha 2 nuclear power plant is completed and starts commercial operation, it will add 745 megawatts to this electrical production capacity. There are two sites with nuclear power plants in Argentina: Atucha and Embalse. The Embalse nuclear power plant went into operation in 1984. At the Atucha site, the Atucha-1 nuclear power plant started operation in 1974. It was the first nuclear power plant in Latin America. Construction of Atucha-2 started in 1981 but advanced slowly due to funding and was suspended in 1994 when the plant was 81 % built. In 2003, new plans were approved to complete the Atucha 2. I summer 2014 the plant went critical for the first time. The construction was completed under a contract with AECL.

Distinguiendo entre la presencia y la dominancia en el mercado local por parte de los bancos extranjeros, el presente trabajo analiza la experiencia argentina en el período 1993-2000. Para este fin, se reconstruyo por primera vez la serie completa de los balances bancarios. Los resultados sugieren que la aumentada presencia de bancos extranjeros no ha producido beneficios significativos, mientras que todo el sistema bancario se ha aventajado por el clima de mayor crecimiento y de estabilidad monetaria. Como parte de la estrategia perseguida por parte del poder público, la creciente dominancia de los bancos extranjeros resulta uno de los factores que han empobrecido la biodiversidad de la banca argentina. De todos modos, parte de los problemas que atormentaron a la economía argentina en los años noventa podrían ser considerados más como el resultado de la adopción de una abertura financiera completa que como consecuencia de la dominancia creciente por parte de los bancos extranjeros.

  20. Geologic map of the Cochetopa Park and North Pass Calderas, northeastern San Juan Mountains, Colorado

    Lipman, Peter W.

    2012-01-01

    The San Juan Mountains in southwestern Colorado have long been known as a site of exceptionally voluminous mid-Tertiary volcanism, including at least 22 major ignimbrite sheets (each 150-5,000 km3) and associated caldera structures active at 33-23 Ma. Recent volcanologic and petrologic studies in the San Juan region have focused mainly on several ignimbrite-caldera systems: the southeastern area (Platoro complex), western calderas (Uncompahgre-Silverton-Lake City), and the central cluster (La Garita-Creede calderas). Far less studied has been the northeastern San Juan region, which occupies a transition between earlier volcanism in central Colorado and large-volume younger ignimbrite-caldera foci farther south and west. The present map is based on new field coverage of volcanic rocks in seventeen 7.5' quadrangles in northeastern parts of the volcanic field, high-resolution age determinations for 120 new sites, and petrologic studies involving several hundred new chemical analyses. This mapping and the accompanying lab results (1) document volcanic evolution of the previously unrecognized North Pass caldera and the morphologically beautifully preserved but enigmatic Cochetopa basin, including unique features not previously described from ignimbrite calderas elsewhere; (2) provide evidence for a more rapid recurrence of large ignimbrite eruptions than previously known elsewhere; (3) quantify the regional time-space-volume progression from the earlier Sawatch magmatic trend southward into the San Juan region; and (4) permit more rigorous comparison between the broad mid-Tertiary magmatic belt in the western U.S. Cordillera and the type continental-margin arc volcanism in the central Andes.

    Fruitland coals are best developed in the north-central part of the San Juan basin. Coal distribution is controlled by shoreline and fluvial depositional settings. Hydraulic gradient, pressure regime, and hydrochemistry reflect regional permeability contrasts. The most productive (>1 MMcf/D) coalbed wells occur along a structural hinge line in association with a regional permeability barrier (no-flow boundary) at the basin center.

We evaluated the dengue incidence and environmental data with Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend test and logistic regressions. Results indicated that dry days are increasing and wet days are decreasing. MSL is increasing, posing higher risk of dengue as the perimeter of the San Juan Bay estuary expands and shorelines move inland. Warming is evident with both SST and AST. Maximum and minimum air surface temperature extremes have increased. Between 1992 and 2011, dengue transmission increased by a factor of 3.4 (95% CI: 1.9–6.1 for each 1 °C increase in SST. For the period 2007–2011 alone, dengue incidence reached a factor of 5.2 (95% CI: 1.9–13.9 for each 1 °C increase in SST. Teenagers are consistently the age group that suffers the most infections in San Juan. Results help understand possible impacts of different climate change scenarios in planning for social adaptation and public health interventions.

    McCrory, Patricia A.; Blair, J. Luke; Waldhause, Felix; Oppenheimer, David H.

    2012-01-01

    A new model of the subducted Juan de Fuca plate beneath western North America allows first-order correlations between the occurrence of Wadati-Benioff zone earthquakes and slab geometry, temperature, and hydration state. The geo-referenced 3D model, constructed from weighted control points, integrates depth information from earthquake locations and regional seismic velocity studies. We use the model to separate earthquakes that occur in the Cascadia forearc from those that occur within the underlying Juan de Fuca plate and thereby reveal previously obscured details regarding the spatial distribution of earthquakes. Seismicity within the slab is most prevalent where the slab is warped beneath northwestern California and western Washington suggesting that slab flexure, in addition to expected metamorphic dehydration processes, promotes earthquake occurrence within the subducted oceanic plate. Earthquake patterns beneath western Vancouver Island are consistent with slab dehydration processes. Conversely, the lack of slab earthquakes beneath western Oregon is consistent with an anhydrous slab. Double-differenced relocated seismicity resolves a double seismic zone within the slab beneath northwestern California that strongly constrains the location of the plate interface and delineates a cluster of seismicity 10 km above the surface that includes the 1992 M7.1 Mendocino earthquake. We infer that this earthquake ruptured a surface within the Cascadia accretionary margin above the Juan de Fuca plate. We further speculate that this earthquake is associated with a detached fragment of former Farallon plate. Other subsurface tectonic elements within the forearc may have the potential to generate similar damaging earthquakes.

    The San Juan Mountains are the largest erosional remnant of a composite volcanic field that covered much of the southern Rocky Mountains in middle Tertiary time. The San Juan field consists mainly of intermediate-composition lavas and breccias, erupted about 35-30 Ma from scattered central volcanoes (Conejos Formation) and overlain by voluminous ash-flow sheets erupted from caldera sources. In the central San Juan Mountains, eruption of at least 8,800 km3 of dacitic-rhyolitic magma as nine major ash flow sheets (individually 150-5,000 km3) was accompanied by recurrent caldera subsidence between 28.3 Ma and about 26.5 Ma. Voluminous andesitic-dacitic lavas and breccias erupted from central volcanoes prior to the ash-flow eruptions, and similar lava eruptions continued within and adjacent to the calderas during the period of more silicic explosive volcanism. Exposed calderas vary in size from 10 to 75 km in maximum dimension; the largest calderas are associated with the most voluminous eruptions.

    The concentration, potential mobility, cation exchange capacity and toxicity of eight sediment-bound metals in Golfe-Juan Bay, France were examined. Results revealed significant spatial gradient of metal contamination along Golfe-Juan coast. The distribution and concentration of the metals appear to be influenced by the geochemical properties of the sediment, proximity to anthropogenic sources and general water circulation in the bay. The portion of trace metals found in the exchangeable, carbonate, oxidizable and reducible fractions of the sediment constitute 31%-58% of the total sediment-bound trace metal content, suggesting significant potential for remobilization of metals into the water column. Pb and Ni content of the sediment exceed the limits of the French marine sediment quality. Whole sediment extracts showed acute toxicity to marine rotifers. This study concludes that monitoring and management of sediment-bound trace metals in Golfe-Juan Bay are important so as not to underestimate their availability and risk to the marine ecosystems.

  18. Mantle flow geometry from ridge to trench beneath the Gorda-Juan de Fuca plate system

    Tectonic plates are underlain by a low-viscosity mantle layer, the asthenosphere. Asthenospheric flow may be induced by the overriding plate or by deeper mantle convection. Shear strain due to this flow can be inferred using the directional dependence of seismic wave speeds--seismic anisotropy. However, isolation of asthenospheric signals is challenging; most seismometers are located on continents, whose complex structure influences the seismic waves en route to the surface. The Cascadia Initiative, an offshore seismometer deployment in the US Pacific Northwest, offers the opportunity to analyse seismic data recorded on simpler oceanic lithosphere. Here we use measurements of seismic anisotropy across the Juan de Fuca and Gorda plates to reconstruct patterns of asthenospheric mantle shear flow from the Juan de Fuca mid-ocean ridge to the Cascadia subduction zone trench. We find that the direction of fastest seismic wave motion rotates with increasing distance from the mid-ocean ridge to become aligned with the direction of motion of the Juan de Fuca Plate, implying that this plate influences mantle flow. In contrast, asthenospheric mantle flow beneath the Gorda Plate does not align with Gorda Plate motion and instead aligns with the neighbouring Pacific Plate motion. These results show that asthenospheric flow beneath the small, slow-moving Gorda Plate is controlled largely by advection due to the much larger, faster-moving Pacific Plate.

    1985-05-01

    During the Tertiary, the western part of the northern Sange de Cristo Range dropped 16,000 ft (4877 m) to become what is now known as the San Luis basin. The foreland basin formerly adjacent to and west of the range remained intact but was subsequently concealed by 10,000 ft (3048 m) of volcanic deposits. The existence of this concealed basin, a northeastern arm of the San Juan basin, was first suggested by Vincent Kelly who named it the San Juan sag. Oil, which was generated in the underlying Mancos Shale, migrated upward into vesicles and fractures in volcanic rocks. In at least two places, oil is currently seeping onto the volcanic surface or into overlying soil. These oil occurrences encouraged geologic and geophysical exploration and have led to confirmation by drilling that the basin exists. Porous reservoirs in both tertiary sedimentary rocks and volcanic rocks overlie a 2000 ft (610 m) Cretaceous Mancos Shale source rock. Within the Mancos Shale are fractured reservoirs, volcanic sills that have reservoir potential where fractured or porous, and stray sandstones. The Dakota Formation underlies the Mancos Shale and is about 200 ft (61 m) thick in this area. In addition, the Jurassic section has potential for source rocks in the Todilto Formation and reservoir rocks in the Entrada and Junction Creek Sandstones. The San Juan sag, a newly discovered basin of 2600 miS (6734 kmS) is a frontier for Colorado oil and gas exploration.

  17. An Investigation of Crust and Upper Mantle Structure in Western Argentina Utilizing Local Event Receiver Functions

    Science.gov (United States)

    Calkins, J. A.; Zandt, G.; Gilbert, H.; Beck, S.

    2004-12-01

    Images of the crust-mantle boundary and crustal structure obtained using the traditional analysis of teleseismic receiver functions (RFs) exhibit an unusually weak P-S conversion from the Moho in Western Argentina, where the subducting Nazca plate temporarily flattens out beneath the overriding South American plate. In order to better estimate depth to the Moho and search for mid-crustal impedance contrasts, we calculate and stack receiver functions using approximately 45 local earthquakes occurring in the downgoing slab between December of 2000 and February of 2001. The events occurred over a depth range of 76 to 165 km and were all within 128 km horizontal distance of the recording station and thus traveled with ray parameters less than .09 s/km. Radial receiver functions are calculated at two temporary broadband seismic stations located between San Juan and Mendoza, in the region where the Precordillera transitions eastward to the Sierras Pampeanas. Plots of stacked RFs as a function of ray parameter show a strong signal from the Moho at 7 seconds corresponding to a depth near 50 km, as well as conversions from interfaces within the crust at depths of ˜ 20 and 35 km. It should be noted that the narrow time interval between the P and S arrivals, due to the close proximity of events to the stations, precludes the analysis of reverberations within the crust to better constrain crustal Vp/Vs estimates and to refine the depth to interfaces. The observed Moho depth is in good agreement with estimates made using Pn apparent phase velocities along a transect through tectonically similar terrain 200 km to the north. In both cases, areas of relatively low topography are underlain by anomalously thick crust. The discrepancy in the clarity of the Moho Ps between RFs obtained using teleseismic versus local events currently remains unexplained but is an area of ongoing research.

  18. The Literary Criticism and Memoirs of Juan Ramón Jiménez

    Directory of Open Access Journals (Sweden)

    Allen W. Phillips

    1983-01-01

    Full Text Available Equally as demanding of others as he was of himself, Juan Ramón Jiménez conceived of literary criticism as a serious and exacting task. The critic and the poet, standing side by side, are devoted to complementary activities of mutual enrichment. However fragmentary and partial the critical opinions of Juan Ramón may be (also outspoken and polemical in nature, they are invaluable as a personal historical and aesthetic guide to about fifty or sixty years of Hispanic literary development (1900-1960. Not to take them into account is to fail to recognize a highly important aspect of his total artistic personality. These varied critical texts are a product of a first rate intelligence and the sensibility of a writer of consummate discrimination who was endowed not only with an excellent memory but also a very special talent for appreciating the authentic. Juan Ramón as a critic is quick to praise (San Juan, Bécquer, Dario, Unamuno and Machado and at the same time strong in his censure of certain contemporaries. Several recently collected volumes of miscellaneous critical materials have resolved the bibliographical muddle for the initial study of this fundamental aspect of the poet, but still particularly important are the expressionistic portraits of Españoles de tres mundos , longer tributes to Valle, Ortega and Villaespesa as well as the extensive lectures delivered in his latter years. Examination of these pages gives us an historical and creative overview of the period in which he lived and worked in addition to original considerations about the evolution of Hispanic poetry. Of course, one of the constant focal points of his literary criticism was the modernist epoch of his early days, a movement or attitude which he considered to be a modern twentieth century renaissance. Together with detailed study of these two areas of historical and aesthetic nature, in the ensuing pages some conclusions are pointed out as to the essence of poetry

    Multibeam data collected using a Kongsberg EM122 sonar system on the NOAA ship R/V Marcus G. Langseth led by chief scientist Douglas Toomey (University of Oregon) in 2009 and with a Simrad EM302 sonar system on two NOAA ship Okeanos Explorer cruises led by chief scientists James Gardner (University of New Hampshire) and Catalina Martinez (University of Rhode Island) in 2009 show the morphology of the Juan de Fuca and Gorda Ridges, as well as the Blanco and Mendocino Fracture Zones. These ridges and fracture zones comprise the divergent plate boundary of the eastern edge of the Pacific Plate and the western edges of the Juan de Fuca and Gorda Plates. Both plates are being subducted beneath the western edge of the North American Plate. CARIS HIPS 8.1 software was used to process the multibeam data and create bathymetric images. The ridge axes, located off the coast of Washington and Oregon (USA) adjacent to the Cascadia Basin, indicate obvious signs of spreading, due to the series of faults and rocky ridges aligned parallel to the plate boundaries. Fault and ridge orientations are used to compare the direction of seafloor spreading, and indicate that both the Juan de Fuca Plate and Gorda Plate are spreading in a southeastern direction. Younger ridges from the Gorda Ridge system mapped in the study run parallel to the boundary, however older ridges do not show the same orientation, indicating a change in spreading direction. The presence of hydrothermal vents along the Juan de Fuca Ridge is also evidence of the active boundary, as the vent chimneys are composed of minerals and metals precipitated from the hot water heated by magma from beneath the spreading seafloor. In this study, the data are used to compare and contrast earthquake seismicity and ridge morphologies at a depth range of approximately 762 to 2134 meters. The diverging Pacific, Juan de Fuca, and Gorda Plates along with the San Andreas Fault have potential to increase seismic and volcanic activity around

    A gravimetric analysis over the Tulum Valley was made. This data was used to reveal the structural setting of the Tulum Fault System situated in the southeastern part of San Juan province in the arid western part of Argentina. This system is the boundary between two geological provinces, the eastern Precordillera Oriental and the Sierras Pampeanas Occidentales. Gravity data was processed using upward continuation and vertical derivative filters and all the results were compared with the geomorphological and the drainage systems maps of the area. Our assessment confirms the presence of two structures in the Pampeano basement with positive anomalies similar to those found in Valdivia and Barboza hills, two important depocenters with low gravimetric gradients separated by a zone with higher gravity anomalies than the depocenters to the east and west. In view of this, a structural map is proposed for the area. This system is important not only because it is the boundary between two geological provinces and has significance regarding regional tectonic issues but also because it controls the surface drainage, soils distribution and groundwater flow of the Tulum basin conditioning the land use distribution.

  6. Institutos privados de investigación “pura” versus políticas públicas de ciencia y tecnología en la Argentina (1943-1955

    Directory of Open Access Journals (Sweden)

    Hurtado, Diego

    2013-06-01

    Full Text Available In June 1943 took place a coup d’etat in Argentina that initiated a process of confrontation between an important sector of academic scientists and the de facto military government. As a result, many scientists lost their positions at universities, between them a group of biomedical scientists led by the physiologist Bernardo Houssay, who was to be awarded the Nobel Prize in Physiology in 1947. From that moment on, supported by local philanthropists and the Rockefeller Foundation, Houssay’s group began to promote the creation of a series of private research institutes. This process continued during the democratic government of Juan Perón (1946-1955. This article analyzes this “project” —its motivations and objectives— as a process of “parallel” institutionalization which was divergent from the initiatives promoted for science and technology by the public sector. This “splitting” of the institutionalization process, embodied in ideologies, institutional models and hardly compatible epistemic hierarchies, would have far-reaching consequences for the future development of research in Argentina.En junio de 1943 se produjo en la Argentina un golpe de Estado que inició un proceso de enfrentamientos entre un importante sector de científicos académicos y el gobierno militar de facto. Como resultado, muchos científicos perdieron sus cargos en las universidades, entre ellos el grupo liderado por el fisiólogo Bernardo Houssay, que iba a obtener el premio Nobel de Fisiología en 1947. A partir de ese momento, este grupo de médicos impulsaron la creación de una serie de institutos privados de investigación sostenidos por filántropos locales y por la Rockefeller Foundation.

    2006-12-01

    Full Text Available Los procesos de licuefacción han ocasionado los efectos más destructivos durante los principales terremotos ocurridos en la Argentina. Sin embargo, a excepción de la provincia de San Juan, los estudios referidos a estos fenómenos son escasos, fundamentalmente debido a la pobre preservación de las estructuras. Aunque los fenómenos de licuefacción han sido descriptos en muchas regiones sísmicas del mundo, en Argentina sus efectos han sido subestimados. Después de la colonización española, se han registrado al menos trece terremotos con características destructivas y fenómenos de licuefacción asociados (1817, 1861, 1844, 1894, 1899, 1920, 1927, 1929, 1944, 1948, 1949, 1952 que han impactado negativamente en el desarrollo y la economía de la región a lo largo de los últimos 200 años. Sin embargo, no existe una relación clara entre sus epicentros y las principales estructuras cuaternarias y en la mayoría de los casos, tampoco se han reconocido superficies de ruptura histórica asociadas, a excepción de las observadas en la La Laja (1944, Lago Fagnano (1949 y Niquizanga (1977. También es probable que muchos de los terremotos de gran magnitud se hayan caracterizado por deformaciones distribuidas en plegamientos y fracturación secundaria, antes que en rupturas superficiales. Durante estos sismos, los efectos de licuefacción fueron los resultados más espectaculares de las sacudidas sísmicas, ocasionando gran parte de los daños. Por ello, el estudio de los terrenos que presentan las condiciones físicas y litológicas susceptibles de sufrir procesos de licuefacción durante la ocurrencia del movimiento sísmico en las áreas pobladas de la Argentina, resulta un campo de investigación prioritario para realizar una adecuada planificación urbana y de obras de infraestructura, elementos vitales para el desarrollo de la región oeste del territorio.Liquefaction phenomena have caused the most destructive effects during the main

    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

  13. PRIMERAS APROXIMACIONES AL ANÁLISIS DE LOS MARCADORES DE ETNICIDAD EN LAS PAUTAS ALIMENTARIAS DESDE LA ZOOARQUEOLOGÍA HISTÓRICA (Diet and Markers of Ethnicity in the Historical Zooarchaeology of Rosario, Argentina: A Preliminary Assessment

    Full Text Available Desde el análisis de los restos óseos de fauna en sitios históricos, se pueden indagar diferentes líneas de investigación relacionadas con la alimentación. Una de estas temáticas es la evidencia sobre etnicidad y la interacción entre poblaciones nativas e inmigrantes desde la perspectiva de la alimentación. El objetivo de esta comunicación es presentar los avances en este sentido, en relación a tres sitios arqueológicos de la ciudad de Rosario, Santa Fe (Argentina entre los siglos XVIII y XIX: Casa Parroquial, Juan Manuel de Rosas y La Basurita. La particularidad de los mismos radica en el hecho histórico de la masiva llegada de inmigrantes hacia mediados del siglo XIX y el consiguiente crecimiento de la ciudad con el pasaje de los siglos. La hipótesis es que estos cambios se reflejaron en el registro arqueológico, tanto en las especies preferidas para el consumo como en las formas de prepararlos. ENGLISH: Historical zooarchaeology provides a means to investigate various lines of research related to food and ethnicity. This article presents a preliminary assessment of dietary evidence of interaction between immigrants and native populations using collections from three archaeological sites in the city of Rosario, Santa Fe (Argentina, all dated between the eighteenth and nineteenth centuries: Casa Parroquial, Juan Manuel de Rosas and La Basurita. There was a major influx of immigrants into Rosario into the mid-nineteenth century, a process we hypothesize should be reflected in changes in both the species consumed and methods of food preparation.

  14. Sexual Politics and Religious Actors in Argentina

    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.

    Monitoring of resistance of Aedes aegypti to temephos was implemented in the provinces of Formosa and Misiones, Argentina, as a response to the need to improve the vigilance for the dengue vector in areas of high risk of dengue. Eggs collected in each locality were reared, and susceptibility to temephos was assayed using larval bioassays. A weak decrease in susceptibility of larvae to temephos was observed in Clorinda and Puerto Iguazú, indicating an incipient resistance with a resistance ratio of 3. No control failures have been observed yet, and this program should allow the early detection of a real problem in our country.

  17. Clientelism and Political Control in Rural Argentina

    Full Text Available Scholarship on clientelism frequently addresses political clientelism using strong ideological presuppositions and/or neglecting its subjective dimension. In this article I explore political clientelism in a rural community of the province of Formosa, Argentina from the peasants' point of view. The results suggest that peasants consider the clientelist relation as one that recognizes their personal needs, while the bureaucracy of the state does not. Thus, they perceive clientelist ties as legitimate, criticizing only the fact that the provision of resources by patrons takes place only during elections.
