    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 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.

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

    Science.gov (United States)

    Suvires, Graciela M.

    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.

    This study contributes to the current knowledge about air pollution in the province of San Juan, Argentina. Sampling was carried out to measure the fine particulate matter in the atmosphere (PM2.5) of the city of San Juan. PM2.5 was collected continuously during the winter and spring seasons of 2014 and 2015, and the concentrations of 14 elements (Pb, Ca, K, Cd, Ni, Cr, Mn, V, Cu, Ti, Ba, Co, Sr, and Fe) were determined in PM2.5 filters using the technique of X-ray fluorescence by synchrotron radiation (SR-XRF). The results revealed that PM2.5 presented annual and seasonal variations, showing a higher concentration during the winter seasons. In addition, for the elements quantified in the filters, a multivariate analysis (Positive Matrix Factorization) was performed to identify the main sources of emission of these elements in the study area, with a series of components being obtained that corresponded to their compositions, which were assigned physical meanings. The first factor, which was the most important in contribution of the sum of the measured elements (45%), was determined mainly by the elements K, Ti, V, Mn, and Fe, which came predominantly from soil particles. The second factor contributed 30% to the measured species in PM2.5, with higher Ba and Zn content perhaps being related to emissions from vehicular traffic. Finally, the third factor, in which Pb, Cr, and Ca predominated, may be an indicator of industrial activity and contributed 25% of the sum of the measured elements of PM2.5. The results of this study provide the first PM composition database in the province, and this can now be used in the development of mitigation and prevention programs.

    This work shows the strategy followed for the co-location of the Satellite Laser Ranging (SLR) ILRS 7406 telescope and the antenna of the permanent Global Positioning System (GPS) station, located at the Félix Aguilar Astronomical Observatory (OAFA) in San Juan, Argentina. The accomplishment of the co-location consisted in the design, construction, measurement, adjustment and compensation of a geodesic net between the stations SLR and GPS, securing support points solidly built in the soil. The co-location allows the coordinates of the station to be obtained by combining the data of both SLR and GPS techniques, achieving a greater degree of accuracy than individually. The International Earth Rotation and Reference Systems Service (IERS) considers the co-located stations as the most valuable and important points for the maintenance of terrestrial reference systems and their connection with the celestial ones. The 3 mm precision required by the IERS has been successfully achieved.

    Esper Angillieri, María Yanina

    2017-01-01

    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.

    Full Text Available

    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.

  1. Field imaging spectroscopy and inferring a blind thrust earthquake history from secondary faulting: 1944 San Juan Earthquake, Argentina

    Science.gov (United States)

    Ragona, Daniel Eduardo

    The studies presented in this dissertation provide new approaches to extract paleo-earthquake information from the geological record. The first chapter describes the development of Field Imaging Spectroscopy, a new methodology for data acquisition and analysis in paleoseismology. The study shows the steps followed from data acquisition, pre-processing, processing and analysis of high spatial and spectral resolution images obtained from cores and a large sample from a fault zone collected at Hog Lake, San Jacinto Fault, Southern California. The study demonstrate that hyperspectral data can be obtained in the field using portable scanners and that high spatial and spectral resolution in the visible to short wave infrared provide a way to enhance subtle or invisible stratigraphic and structural features. The second chapter focuses on the use of neural networks and naive Bayesian classifiers to automatically classify hyperspectral image data, providing an objective mapping of the structure of cores, samples and field exposures. The results of this study show that a system integrated by a hyperspectral scanner and pattern recognition algorithms can work as an enhanced eye and an objective classifier to provide the geologist with additional information that facilitates the final description, interpretation and correlation of the geology in paleoseismic exposures and cores. The hyperspectral dataset collected together with a spectral library of the materials observed in the excavation provide a new way to archive paleoseismological data for future analysis. Finally, in chapter 3, an innovative approach to study blind thrust faults is presented. The study of the secondary La Laja fault near San Juan, Argentina shows that the earthquake history recorded in a minor fault provides an indirect way to study the occurrence of large M˜7 earthquakes at depth. This investigation also provides the first and perhaps the longest record of the earthquake activity of a blind thrust

    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.

    This contribution presents the description and interpretation of carbonate microfacies of the San Juan Formation (Ordovician) at the Niquivil section, considering the stratigraphical interval between the Oepikodus evae and Oepikodus intermedius conodont zones. The distribution of the microfacies and the conodonts assemblages allow us to identify different sub-environments within the late Floian carbonate ramp of the Central Precordillera. Five microfacies were recognized from the base to the top: M1 Bioclastic mudstone-wackestone; M2 Bioclastic-peloidal wackestone; M3 Intra-bioclastic wackestone; M4 Intra-bioclastic packstone; M5 Peloidal grainstone. The vertical distribution of these microfacies indicates a shallowing trend of the carbonate ramp in the Niquivil section for this temporal interval, which suggests a middle ramp environment with low energy, without wave action, and that evolved towards the middle-inner ramp environment with more energy by wave action and development of tempestites.

El análisis de las microfacies y los conodontos asociados permiten el reconocimiento de diferentes subambientes carbonáticos dentro de la rampa carbonática desarrollada durante el Floiense tardío de la Precordillera Central.

    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

  10. On the existence of potential source rocks in the lower Paleozoic carbonate sequence of the Precordillera, San Juan, Argentina

    The Precordillera of western Argentina is a terrane that comprises a thick Upper Cambrian-Lower Ordovician carbonate sequence corresponding to a stable platform developed over a [open quotes]Pampean[close quotes] basement. Several authors have considered this terrane as allochthonous, on the internal border of the Andean Mobile Belt; but it is more possible to assign it to a parauthochthonous origin with minor relative displacements. The presence of kerogen has been detected at an interval comprising the Zonda (Cambrian) and San Roque (Cambrian-Tremadocian) formations, which correspond to calcareous intertidal to lagoonal sequences deposited in restricted carbonate platforms and grading into supratidal facies to the east (shoreline). The Zonda Formation includes dark wackestones, with oolites, intraclasts and peloids, gray to brownish carbonates with high fenestral porosity, showing fine lamination and stromatolites, and light-colored dolomitic mudstones with voids filled with sparite. As the result of sea-level changes, this part of the sequence shows typical dissecation structures and increased fracture porosity with kerogen fillings. The San Roque Formation is mainly formed by dolomitic mudstones showing bird's eyes filled with kerogen and strong evidence of dissecation and dehydration. Hydrocarbons always appear as partial fillings of fractures; also included in granular sparite veins or between microsparite bands in the laminated carbonates. These kerogen shows are the first described in Lower Paleozoic rocks in Argentina, and are tentatively assigned to changes in sea-level and the last stages of the Cambrian Great Cycles in South America. These new potential source rocks open new frontiers for petroleum exploration in the Cuyo Basin and prove potential plays in Lower Paleozoic rocks, as have been described in several basins of North America, China, and Australia.

    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

    The aim of this research work is to characterize bentonites, both physically and chemically, as well as mineralogically, from deposits located in the Argentine provinces of San Juan and Rio Negro. The study is completed with technological assays to evaluate the quality of the samples under study so as to determine possible industrial uses and/or applications for this material. To carry out this work, four samples of bentonite, identified as M1, M3, and M4, from the province of San Juan, and another, identified as M2, from the province of Rio Negro were used. Physical characterization consisted of determining: swelling, density, moisture, pH and specific gravity of the bentonite samples through application of a number of techniques. Chemical characterization of major components was carried out by using wet methods through acid attack, whilst ICP was used to characterize minor components. Mineralogical characterization was carried out by using an infrared spectrometer. The technological assays for evaluating the quality of the bentonite were carried out following the method indicated by the API and SEGEMAR standards, among others, in order to determine possible uses and/or applications, mainly in the oil and ceramics industries It was found that the M2 bentonite is the most suitable to be used as a drilling mud as it meets the requirements specified by the API standards. The M3 bentonite, due to its physico-chemical characteristics such as low rheology, swelling, low iron content, amongst others, is the most suitable for the ceramics industry. (Author)

La mención de algunos antecedentes sobre un siglo de trayectoria vitivinícola permiten apreciar con mayor claridad las transformaciones recientes de la agroindustria y el papel de los diferentes actores sociales involucrados. Particularmente destacados son los cambios operados por el Estado, que actuó como promotor, regulador y empresario, desregulador y, nuevamente, promotor, pero siempre articulado con los sectores empresarios. El acelerado proceso de cambios desde la década de 1990 supuso una reorientación de la actividad, otrora concentrada en el mercado interno, para posicionar a la región en lugares de creciente relevancia en el mercado internacional de vinos finos. El análisis a escala regional se complementa, finalmente, con los cambios que se producen a escala de empresas y las estrategias que desarrollan para crecer y competir.

    Full Text Available La tonelería fue una de las actividades inducidas por la vitivinicultura moderna en San Juan desde fines del siglo XIX. La mayoría de los toneleros fueron inmigrantes provenientes de países vitivinícolas europeos, principalmente españoles e italianos. Fundaron talleres autónomos o, la mayoría, trabajaron en las tonelerías que funcionaron en el interior de las bodegas. Además de identificar los toneleros que abrieron sus propias unidades de producción, el trabajo destaca, entre otros aspectos, el rol de los comerciantes de vasijas y madera para reparar y armar los envases así como algunos problemas que debió enfrentar la actividad en sus inicios, los vínculos con la actividad metalúrgica y las huelgas de los toneleros que operaban en las bodegas

  1. 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

    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 important

Este trabajo presenta un panorama detallado de la investigación y los métodos usados para realizar una aproximación facial grafica en 2D de un hombre prehistórico del valle de Jachal, provincia de San Juan, Argentina. Se entiende que corresponde a un miembro del extinto grupo Huarpe. El cráneo del individuo muestra numerosos rasgos morfológicos que son consistentes con lo que se conoce acerca de este grupo de agricultores tempranos americanos. Debido a que muchos de los métodos utilizados en esta reconstrucción facial aun no han sido verificados y aquellos que han sido debidamente probados se basan en promedios estadísticos de la variación humana, los resultados presentados deben ser vistos como indicativos de la posible apariencia facial del individuo dado el nivel actual de conocimiento, más que como un resultado definitivo.

Sin embargo, no se han realizado estudios específicos destinados a comprobar su existencia, la cual incluso ha sido negada recientemente. A fin de aclarar el tema se realizó el relevamiento de un sector del Valle de Iglesia. En este artículo se presentan los resultados de ese estudio, junto con una revisión y discusión de los antecedentes y de algunas ideas vinculadas con el tema. Fundamentalmente, se verifica la presencia del Qhapaq Ñan en la parte baja del sector analizado, se refuta la propuesta de que el trazado longitudinal principal se habría extendido por la parte alta del sector precordillerano y se sostiene que el tramo relevado fue recorrido por Debenedetti a principios del siglo XX, aunque sin advertir que se trataba del camino incaico.   Palabras clave: Inca; Camino del Inca; Dominación incaica; Collasuyo; San Juan   Abstract The Inka road system in the longitudinal valleys of San Juan province, in the southeastern end of Tawantinsuyu, has been subject of several considerations during the last century.

This article presents the results of that study, along with a review and discussion of the background and of some ideas related to the topic. Basically, the presence of the Qhapaq Ñan at the bottom of the surveyed sector is verified, and the suggestion that the main inka longitudinal route would have extended over the top of the precordilleran mountain region is refused. Also, it is argued that the analyzed stretch was traveled by Debenedetti in the beginnings of the twentieth century, but without realizing that it was the Inka road.   Keywords: Inka; Inka Road; Inka

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.

    Larval flannelmouth sucker (Catostomus latipinnis) were exposed to arsenate, boron, copper, molybdenum, selenate, selenite, uranium, vanadium, and zinc singly, and to five mixtures of five to nine inorganics. The exposures were conducted in reconstituted water representative of the San Juan River near Shiprock, New Mexico. The mixtures simulated environmental ratios reported for sites along the San Juan River (San Juan River backwater, Fruitland marsh, Hogback East Drain, Mancos River, and McElmo Creek). The rank order of the individual inorganics, from most to least toxic, was: copper > zinc > vanadium > selenite > selenate > arsenate > uranium > boron > molybdenum. All five mixtures exhibited additive toxicity to flannelmouth sucker. In a limited number of tests, 44-day-old and 13-day-old larvae exhibited no difference in sensitivity to three mixtures. Copper was the major toxic component in four mixtures (San Juan backwater, Hogback East Drain, Mancos River, and McElmo Creek), whereas zinc was the major toxic component in the Fruitland marsh mixture, which did not contain copper. The Hogback East Drain was the most toxic mixture tested. Comparison of 96-h LC50values with reported environmental water concentrations from the San Juan River revealed low hazard ratios for arsenic, boron, molybdenum, selenate, selenite, uranium, and vanadium, moderate hazard ratios for zinc and the Fruitland marsh mixture, and high hazard ratios for copper at three sites and four environmental mixtures representing a San Juan backwater, Hogback East Drain, Mancos River, and McElmo Creek. The high hazard ratios suggest that inorganic contaminants could adversely affect larval flannelmouth sucker in the San Juan River at four sites receiving elevated inorganics.

    Climate change has important implications for public health. We developed and tested the hypothesis that conditions for dengue fever transmission in San Juan (Puerto Rico, USA) are becoming favorable as a result of meteorological drivers being modified with climate change. Sea level pressure, mean sea level (MSL), wind, sea surface temperature (SST), air surface temperature (AST), rainfall, and confirmed dengue cases were variables examined over the past 30 years, or longer for some variables. Statistical tools used included Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend tests, and logistic regressions. Results show that dry days are increasing and that wet days are decreasing. MSL is steadily increasing, which increases the risk of dengue cases along the coast, as the perimeter of the San Juan Bay estuary expands and the shoreline moves inland. Warming is evident in both SST and AST. Maximum and minimum air surface temperature extremes have also increased. Incidence of dengue is accelerating along with environmental change. For example, between 2000-2011, dengue transmission increased by a factor of 3.4 (95% CI: 1.9-6.1) for each 1ºC increase in SST. Between 2007 and 2011, this risk factor increased to 5.2 (95% CI: 1.9-13.9) for every 1ºC increase in SST. An important but difficult to examine problem is how social and economic factors affect such dengue fever transmission rates in light of environmental change. A concern is that the patterns observed in San Juan are representative of potential incidence of dengue virus in other parts of the island of Puerto Rico and in other Caribbean nations. These results help understand patterns of disease spreading, and allow public health officials to evaluate scenarios and interventions intended to mitigate the impacts of climate change.

    Full Text Available Commons scholarship has tended to focus on the administration and use of commons by individuals and households and less so on collective enterprises that extract, transform and market what they harvest from the commons. In this paper, we consider Nuevo San Juan, a Mexican case that is well known in the community forestry and commons literature. In San Juan, indigenous community members who hold the rights for the commons are also the members of the enterprise that transforms and markets goods from the commons. We argue that such a strategy is one way to confront internal and external pressures on a commons. We draw upon the transcripts of 40 interviews undertaken during 2006 which are analyzed using a framework developed from the social, community-based and indigenous enterprise literature. Our goal was to utilize this framework to analyze the San Juan Forest Enterprise and understand its emergence and formation as a long-standing community-based enterprise that intersects with a commons, and thereby identify factors that increase chances of success for community enterprises. We found that by starting from the community-based and indigenous enterprise literature and using that literature to engage with thinking on commons, it was possible to consider the enterprise from the perspective of a regulatory framework rather than from the poles of dependency and modernization theories in which much commons work has been based. Enterprise and commons intersect when both are guided by core cultural values and the enterprise can become a new site for the creation of social and cultural cohesion. We also found that there were a number of necessary conditions for commons-based community-enterprises to retain internal and external legitimacy, namely: (1 leadership representative of the broad social mission rooted in the customary institutions, values and norms of the community; (2 accountability of enterprise leaders to the memberships they represent; and (3

    Increased frequency and length of high heat episodes are leading to more cardiovascular issues and asthmatic responses among the population of San Juan, the capital of the island of Puerto Rico, USA. An urban heat island effect, which leads to foci of higher temperatures in some urban areas, can raise heat-related mortality. The objective of this research is to map the risk of high temperature in particular locations by creating heat maps of the city of San Juan. The heat vulnerability index (HVI) maps were developed using images collected by satellite-based remote sensing combined with census data. Land surface temperature was assessed using images from the Thermal Infrared Sensor flown on Landsat 8. Social determinants (e.g., age, unemployment, education and social isolation, and health insurance coverage) were analyzed by census tract. The data were examined in the context of land cover maps generated using products from the Puerto Rico Terrestrial Gap Analysis Project (USDA Forest Service). All variables were set in order to transform the indicators expressed in different units into indices between 0 and 1, and the HVI was calculated as sum of score. The tract with highest index was considered to be the most vulnerable and the lowest to be the least vulnerable. Five vulnerability classes were mapped (very high, high, moderate, low, and very low). The hottest and the most vulnerable tracts corresponded to highly built areas, including the Luis Munoz International Airport, seaports, parking lots, and high-density residential areas. Several variables contributed to increased vulnerability, including higher rates of the population living alone, disabilities, advanced age, and lack of health insurance coverage. Coolest areas corresponded to vegetated landscapes and urban water bodies. The urban HVI map will be useful to health officers, emergency preparedness personnel, the National Weather Service, and San Juan residents, as it helps to prepare for and to mitigate

  13. Deep-coal-bed methane potential of the San Juan River coal region, southwestern Colorado

    Kelso, B.S.; Goolsby, S.M.; Tremain, C.M.

    1980-01-01

    The deepest, highest ranking and probably gassiest coals in the San Juan River coal region of southwestern Colorado are found in the 100 mile (mi) wide San Juan Basin of Colorado and New Mexico. The thickest and most continuous coal beds in the basin are found in the Cretaceous Fruitland Formation. Logs from 231 petroleum exploration drill holes were used to produce the following: a Fruitland Formation isopach, a Pictured Cliffs structure map, Fruitland Formation net coal and net sand isopachs, and Fruitland coal percentage and sand percentage maps. Of the 231 holes, 8 produced natural gas from sandstones in coal bearing zones, 5 were production tested in mixed sandstone and coal intervals (one well had an initial production of 1.6 MMCFGPD), and 5 were drill stem tested in coal bearing zones (one flowed 1 MMCFG in 35 min). The authors calculate 19.7 billion tons of coal are present in the study area. The coals are ranked high-volatile B (hvB) and high-volatile A (hvA) with local upgrading to medium-volatile (mv). Comparing gas contents of Cretaceous Raton Mesa coals to San Juan Basin coals, a gas potential ranging from 72 cubic feet/ton (cu ft/ton) to 514 cu ft/ton exists. The authors estimate a gas resource in the study area ranging from 1.4 to 10.0 trillion cubic feet. The data indicates that gas is present in the coals of the study area. This gas has been produced from sandstones adjacent to the coals and possibly from the coals themselves. Therefore, it might pay to test the Fruitland coals encountered while drilling for deeper targets. With the right economic factors and development of completion techniques for coal bed methane, this gas resource may prove to be important. Data gained from vitrinite reflectance of cuttings, desorption of cuttings, and desorption of conventional cores continue to support the existing evidence that coal bed gas is being generated and trapped in the deeper portion of the San Juan Basin.

    Flow and water-quality changes were studied during a period of intense rainfall in the San Juan Lagoon system. The study covered a 25-hour period beginning 0900 hours 22 October, 1974. Precipitation during the study period averaged 70 millimeters. Sampling stations were located at Boca de Cangrejos, the main ocean outlet; Canal Pinones between Laguna de Pinones and Laguna La Torrecilla; Canal Suarez between Laguna San Jose, connects to Laguna La Torrecilla; and Cano de Martin Pena between Laguna San Jose and Bahia de San Juan. In addition water-elevation recording gages were installed at each lagoon. Water samples from the canal stations were analyzed for organic carbon, nitrogen and phosphorus species, and suspended sediment. Specific-conductance measurements were used with the chemical data to estimate the runoff contributions of nutrients. Runoff into the lagoon, system during the study period was about 2.8 million cubic meters, or about 70 percent of the average precipitation. The runoff contributed chemical loadings to the lagoons of 95,000 kilograms total-organic carbon; 2,700 kilograms of total phosphorus; and 10,000 kilograms of total Khjeldhal nitrogen. A comparison with a prior study during which there was no significant rain, show that dry-period loadings are less than 10 percent of the wet-period loadings. At the end of the study period the system had not reached equilibrium, and the lagoons retained 80 percent of the water inflows from 50 to 90 percent of the chemical loads. Nearly 95 percent of the water outflows occurred at the Boca de Cangrejos sea outlet. The three lagoons and interconnecting canals form a very complex hydraulic system that is difficult to study using traditional techniques. A model of the system will facilitate management to improve the quality of water in the lagoons.

  17. Dinosaur Footprints in Lower Cretaceous Beds in San Juan Raya, Southern Mexico and the Paleoenvironmental Implications

    Dinosaur footprints were traced at San Juan Raya, an important site in Mexico, a world fossil site. This site is found at South-west of the State of Puebla, within the Biosphere Reserve of Tehuacan-Cuitcatlán, to the southwest of the Tehuacan valley. These footprints were recorded by tracing them on transparent paper at Barranca Agua Nueva, at point 18°18.56´N 97°37´W. Using Jacob´s staff a stratigraphic register was generated from 50 m ascending and descending in stratigraphically direction from the bed where footprints were founded. Bivalbes, nerineas, shell fragments, and trigonias were founded in this sequence as well as cross bedding of clays and fine grain sand, some which display ripples. Fifty two footprints were recorded and five different tracks identified, observing two different sizes. The tracks of dinosaur footprints present the common Teropode ichnites. The succession where dinosaur footprints have been found, are interpreted as a peritidal environment. This investigation contributes to an eco-tourism project of San Juan Raya.

    Accelerated climate change and associated forest disturbances in the southwestern USA are anticipated to have substantial impacts on regional water resources. Few studies have quantified the impact of both climate change and land cover disturbances on water balances on the basin scale, and none on the regional scale. In this work, we evaluate the impacts of forest disturbances and climate change on a headwater basin to the Colorado River, the San Juan River watershed, using a robustly calibrated (Nash-Sutcliffe efficiency 0.76) hydrologic model run with updated formulations that improve estimates of evapotranspiration for semi-arid regions. Our results show that future disturbances will have a substantial impact on streamflow with implications for water resource management. Our findings are in contradiction with conventional thinking that forest disturbances reduce evapotranspiration and increase streamflow. In this study, annual average regional streamflow under the coupled climate-disturbance scenarios is at least 6-11 % lower than those scenarios accounting for climate change alone; for forested zones of the San Juan River basin, streamflow is 15-21 % lower. The monthly signals of altered streamflow point to an emergent streamflow pattern related to changes in forests of the disturbed systems. Exacerbated reductions of mean and low flows under disturbance scenarios indicate a high risk of low water availability for forested headwater systems of the Colorado River basin. These findings also indicate that explicit representation of land cover disturbances is required in modeling efforts that consider the impact of climate change on water resources.

    In this article, we narrate and analyze the historical configuration that a group of female workers and a collective of social organizations made about the Hospital San Juan de Dios (HSJD) and Instituto Materno Infantil (IMI) in Bogotá, Colombia, within the neoliberal crisis in health. Our ethnographic research intersects the Latinamerican traditions of collaborative ethnography and historic anthropology. The research was conducted in two sites. In the first one, from 2005 until 2015, we had informal conversations and conducted workshops and semi-structured interviews with IMI workers. The second site corresponds to our participation in the deliberations of the Mesa Jurídica por el San Juan de Dios (2008-2009), which aimed to elevate a class action to defend the hospitals. We found that workers and social organizations made use of the colonial origin of the hospitals and their institutionalization as center of welfare policies in the country as a way to highlight their patrimonial, historical, educational and social importance. This historical construction critiques efforts that negate or transform the public character of the hospitals and helped them carry on different actions to denounce the neoliberal health care reform as the cause of the hospitals most important crisis and closing. The different actors denounce the change in the hospitals-state relationship, which transited from being central for the development of social policies to reflecting a symbolic and material elimination of the hospitals. Such transition benefits the market interests established by the neoliberal model.

  1. Geologic controls on open-hole cavity completions in the San Juan basin

    Energy Technology Data Exchange (ETDEWEB)

    Kelso, B.S. (Advanced Resources International, Inc., Lakewood, CO (United States))

    1994-04-01

    The success of open-cavity-completed wells is measured (1) by how well mechanically the cavity is created, which results in a higher degree of completion efficiency; and (2) by production success, whereby production rates are improved relative to other completion techniques. Open-hole cavitation is highly successful in the San Juan basin fairway, but the technique has not been successful in other areas. Outside the fairway, particularly to the south, operators have not achieved mechanical success with cavity completions. To explain the change in permeability across the southern fairway boundary, an hypothesis is proposed that involves the presence of a northwest-trending basement structure, such as a fault or fault zone. Episodic post-Fruitland movement on the northeastern limb of the structure could have enhanced the fracturing of the coal seams, resulting in higher permeabilities and the higher productivity levels of both cavity and fracture-stimulated wells. Based on the San Juan basin data reviewed, it appears that a combination of adequate permeability, overpressuring, and coal rank of high-volatile A bituminous are required for mechanical success of cavity completions. Although the level of permeability is not quantified, it is the author's opinion that at least 5 md is required. High production rates from cavity-completed wells are a function of better completion efficiency, whereby the wellbore is linked to favorable permeability settings. 5 refs., 10 figs.

El tema es relevante porque Argentina es actualmente la mayor potencia vitivinícola de América Latina y la quinta del mundo. El trabajo se ha realizado a partir de fuentes originales de los archivos de las ciudades de Mendoza, San Juan y Santiago de Chile, con el procesamiento de más de 400 mil datos sobre viñas, parrales y cepas. En el estudio se detectó que el 97% de las cepas se cultivaban en viñas y el solo 3% en parrales encatrados. Dentro de las primeras, el cultivo de las tres cuartas partes se hacía mediante el sistema en vaso, gobelet o cepas de cabeza (como se llamaba en América, mientras que el cuarto restante era embracerado: los sarmientos se conducían con varillas de sauce y álamo.

    The role of remote sensing data as it relates to a three-component land management planning system (geographic information, data base management, and planning model) can be understood only when user requirements are known. Personnel at the San Juan National Forest in southwestern Colorado were interviewed to determine data needs for managing and monitoring timber, rangelands, wildlife, fisheries, soils, water, geology and recreation facilities. While all the information required for land management planning cannot be obtained using remote sensing techniques, valuable information can be provided for the geographic information system. A wide range of sensors such as small and large format cameras, synthetic aperture radar, and LANDSAT data should be utilized. Because of the detail and accuracy required, high altitude color infrared photography should serve as the baseline data base and be supplemented and updated with data from the other sensors.

    An action plan is being formulated for the San Juan River basin, shared by Costa Rica and Nicaragua in Central America. The action plan is assumed to be a planning tool designed to ensure the availability of the goods and services that water resources provide for the conservation of ecosystems and for social and economic development. Development of the action plan comprises two phases, namely elaboration of the diagnostic study and drafting of the action plan. The diagnostic study was published in 1997. After examining previous cases in international water systems, for which the diagnostic study was developed as the precursor of an action plan, the author felt that the existing diagnostic study for the San Juan River basin still had room for improvements, in particular in the following aspects: (a) inventory of past, ongoing and future projects; (b) impacts of reserved areas on the basin as a whole; (c) instruments to promote public participation; (d) support by central decision makers; (e) mechanisms for information transparency. These aspects, which need enhancements, seem to suggest that more emphasis should be put on the soft aspects of the sciences. While the diagnostic study addresses issues of natural environment in detail, both data and analysis of human environments are in low profile. The lesson gained from the Zambezi River basin project is that lack of a proper strategy and political commitments by the central decision makers (of the riparian states) will lead to an impasse in implementation of the project, due mainly to paucity of support within basin countries. Lack of support by the general public may also lead to a failure in the implementation phase. These aspects should have been sufficiently addressed in the diagnostic study, so that appropriate actions (to be listed in the action plan) should be elaborated for implementation.

  16. Base of moderately saline ground water in San Juan County, Utah

    The base of moderately saline ground water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was delineated for San Juan County, Utah, based on water-quality data and on formation-water resistivities determined from geophysical well logs using the resistivity-porosity, spontaneous-potential, and resistivity-ratio methods. These data and the contour map developed from them show that a thick layer of very saline to briny ground water (water that contains more than 10,000 milligrams per liter of dissolved solids) underlies the eastern two-thirds of San Juan County. The upper surface of this layer is affected by the geologic structure of the area, but it may be modified locally by recharge mounds of less saline water and by vertical leakage of water through transmissive faults and fractures. The highest altitude of the base of moderately saline water is west of the Abajo Mountains where it is more than 6,500 feet above sea level. The lowest altitude is in the western part of the county and is below sea level: depressions in the base of moderately saline water in recharge areas in the La Sal and Abajo Mountains also may be that low. The base of moderately saline water commonly is in the Permian Cutler Formation or the Pennsylvanian Honaker Trail Formation of the Hermosa Group, but locally may be as high stratigraphically as the Triassic (?) and Jurassic Navajo Sandstone north of the Abajo Mountains and in the Jurassic Morrison Formation south of the mountains.

    Extreme heat episodes are becoming more common worldwide, including in tropical areas of Australia, India, and Puerto Rico. Higher frequency, duration, and intensity of extreme heat episodes are triggering public health issues in most mid-latitude and continental cities. With urbanization, land use and land cover have affected local climate directly and indirectly encouraging the Urban Heat Island effect with potential impacts on heat-related morbidity and mortality among urban populations. However, this association is not completely understood in tropical islands such as Puerto Rico. The present study examines the effects of heat in two municipalities (San Juan and Bayamón) within the San Juan metropolitan area on overall and cause-specific mortality among the population between 2009 and 2013. The number of daily deaths attributed to selected causes (cardiovascular disease, hypertension, diabetes, stroke, chronic lower respiratory disease, pneumonia, and kidney disease) coded and classified according to the Tenth Revision of the International Classification of Diseases was analyzed. The relations between elevated air surface temperatures on cause-specific mortality were modeled. Separate Poisson regression models were fitted to explain the total number of deaths as a function of daily maximum and minimum temperatures, while adjusting for seasonal patterns. Results show a significant increase in the effect of high temperatures on mortality, during the summers of 2012 and 2013. Stroke (relative risk = 16.80, 95% CI 6.81-41.4) and cardiovascular diseases (relative risk = 16.63, 95% CI 10.47-26.42) were the primary causes of death most associated with elevated summer temperatures. Better understanding of how these heat events affect the health of the population will provide a useful tool for decision makers to address and mitigate the effects of the increasing temperatures on public health.

    Full Text Available I examined the multiple visions of the future of the city that can emerge when city actors and organizations reconfigure themselves to address sustainability. In various cities worldwide, novel ideas, initiatives, and networks are emerging in governance to address social and ecological conditions in urban areas. However, cities can be contested spaces, bringing a plurality of actors, network configurations, preferences, and knowledge that shape the politics over desirable pathways for future development. I used the knowledge-action systems analysis (KASA approach to examine the frames and knowledge systems influencing how different actors involved in the land governance network of the city of San Juan constructed visions for the future of the city. Results revealed four visions for the city coexisting in San Juan. Although sustainability is a goal that cuts across all four visions, they each optimized distinct dimensions of the concept. The contrasts in visions can be explained in part by competing frames of the urban social-ecological system and power asymmetries in the multiple knowledge systems coexisting in the city. I discussed the theoretical, methodological, and practical implications of the politics of sustainability for adaptive urban governance research and practice. The KASA approach can serve as a window into the adaptive capacity of the city by disentangling the competing ways that actors 'see' and 'know' the urban social-ecological systems. Most importantly, this approach offers a way of appraising sustainable pathways by revealing either the extent to which dominant social structures and cognitive patterns are being reinforced, or whether opportunities for innovative and transformative approaches are emerging in the city.

  20. Eruptive and noneruptive calderas, northeastern San Juan Mountains, Colorado: Where did the ignimbrites come from?

    The northeastern San Juan Mountains, the least studied portion of this well-known segment of the Southern Rocky Mountains Volcanic Field are the site of several newly identified and reinterpreted ignimbrite calderas. These calderas document some unique eruptive features not described before from large volcanic systems elsewhere, as based on recent mapping, petrologic data, and a large array of newly determined high-precision, laser-fusion 40Ar/39Ar ages (140 samples). Tightly grouped sanidine ages document exceptionally brief durations of 50-100 k.y. or less for individual Oligocene caldera cycles; biotite ages are more variable and commonly as much as several hundred k.y. older than sanidine from the same volcanic unit. A previously unknown ignimbrite caldera at North Pass, along the Continental Divide in the Cochetopa Hills, was the source of the newly distinguished 32.25-Ma Saguache Creek Tuff (???400-500 km3). This regionally, distinctive crystal-poor alkalic rhyolite helps fill an apparent gap in the southwestward migration from older explosive activity, from calderas along the N-S Sawatch locus in central Colorado (youngest, Bonanza Tuff at 33.2 Ma), to the culmination of Tertiary volcanism in the San Juan region, where large-volume ignimbrite eruptions started at ca. 29.5 Ma and peaked with the enormous Fish Canyon Tuff (5000 km3) at 28.0 Ma. The entire North Pass cycle, including caldera-forming Saguache Creek Tuff, thick caldera-filling lavas, and a smaller volume late tuff sheet, is tightly bracketed at 32.25-32.17 Ma. No large ignimbrites were erupted in the interval 32-29 Ma, but a previously unmapped cluster of dacite-rhyolite lava flows and small tuffs, areally associated with a newly recognized intermediate-composition intrusion 5 ?? 10 km across (largest subvolcanic intrusion in San Juan region) centered 15 km north of the North Pass caldera, marks a near-caldera-size silicic system active at 29.8 Ma. In contrast to the completely filled North Pass

    The Cretaceous strata that fill the San Juan Basin of northwestern New Mexico and southwestern Colorado were shortened in a generally N-S to NN13-SSW direction during the Laramide orogeny. This shortening was the result of compression of the strata between southward indentation of the San Juan Uplift at the north edge of the basin and northward to northeastward indentation of the Zuni Uplift from the south. Right-lateral strike-slip motion was concentrated at the eastern and western basin margins of the basin to form the Hogback Monocline and the Nacimiento Uplift at the same time, and small amounts of shear may have been pervasive within the basin as well. Vertical extension fractures, striking N-S to NNE-SSW with local variations (parallel to the Laramide maximum horizontal compressive stress), formed in both Mesaverde and Dakota sandstones under this system, and are found in outcrops and in the subsurface of the San Juan Basin. The immature Mesaverde sandstones typically contain relatively long, irregular, vertical extension fractures, whereas the quartzitic Dakota sandstones contain more numerous, shorter, sub-parallel, closely spaced, extension fractures. Conjugate shear planes in several orientations are also present locally in the Dakota strata.

  4. Restoring sedges and mosses into frost heaving iron fens, San Juan Mountains, Colorado

    2011-08-01

    Full Text Available Rare iron fens in the San Juan Mountains of Colorado are frequently in poor condition due to mining, roads and ditches, which have left much of the fen completely bare of vegetation. Natural revegetation is slow to occur in the bare areas because of severe frost heave in the cold mountain climate. Therefore, experimental revegetation plots were conducted in a factorial design with mulching and no mulching, crossed with moss diaspores, sedge transplants, and moss and sedge combined. Mulching influenced surface soil temperatures by reducing the midday highs and increasing the night-time lows, which decreased the frequency and amount of frost heave. Peat moisture also modified frost heave, with the greatest frost heaving occurring near 75 % peat moisture content (water table 10–20 cm below the surface and the least when soils were either wetter or drier. Moss survival was dependent on mulch, with no moss surviving in plots without mulch. Mulching also increased sedge transplant survival. In summary, mulching significantly increased the success of vegetation restoration efforts for frost heave areas in mountain fens.

    Coalbed methane wells in the San Juan basin can be highly profitable, with gas production up to about 10 MMcf/D at depths of about 3,000 ft, if the wells are successfully completed with the openhole cavity technique. The authors report the first measurement of cavity size (radius of about 5 ft) and shape. A vanity can resemble a cylindrical bookcase with shale ledges like shelves. They also report correlations between successful cavity completions and such reservoir/rock parameters as compressive strength, coal rank, permeability, and reservoir pressure (for example, there is no correlation with the minimum coal compressive strength). In this area, wells completed with the openhole cavity technique often produce roughly 10 times more gas than wells completed with hydraulic fracture stimulations. Wellbore mechanics associated with the cavity--e.g., the enlarged wellbore plus enhanced permeability beyond the cavity--does not seem to explain the cavity/fracture production discrepancy. A number of other possibilities are explored, including permeability anisotropy and completion damage to the reservoir or fracture. Severe damage apparently is associated with hydraulic fracture stimulations in the fairway zone, which would explain their poor performance compared with cavity wells.

    The San Juan Mountains of southwestern Colorado contain numerous lakes and bogs at and above treeline. In June 1978, Lake Emma, a tarn above present-day treeline, was suddenly drained by the collapse of underground mine workings. This study was initiated because the draining exposed a well-preserved archive of subfossil coniferous wood fragments that provided a unique opportunity to further our understanding of the paleoclimatic history of this region. These paleoclimatic studies-coniferous macrofossil identification in conjunction with radiocarbon dating, deuterium analysis of the dated conifer fragments, as well as pollen and fossil insect analyses-yielded new information regarding Holocene climate and accompanying treeline changes in the northern San Juan Mountains. This report synthesizes previously published reports by the author and other investigators, and unpublished information of the author bearing on late Pleistocene and Holocene treeline and climate in this region. Retreat of the glacier that occupied the upper Animas River valley from its Pinedale terminal position began about 19.4 + or - 1.5 10Be thousands of years ago and was essentially complete by about 12.3 + or - 1.0 10Be thousands of years ago. Two sets of late Pleistocene cirque moraines were identified in the northern San Juan Mountains. The older set is widespread and probably correlates with the Younger Dryas (11,000-10,000 radiocarbon years before present; 12,800-11,500 calendar years). The younger set is found only in the Grenadier Range and represents remnant glacier ice lying in well-shaded niches in a mountain range undergoing rapid deglaciation. A snowbank at the northern base of this range appears to be fronted by a Little Ice Age moraine. Soon after deglaciation the average July temperature is estimated to have been about 5°C cooler and timberline about 650 meters lower than at present. However, timberline (and treeline) responded rapidly to the postglacial warming and reached

    A description of a cogeneration plant in San Juan del Rio, Mexico was presented. The Arancia-Corn Products, S.A. de C.V. corn processing plant makes use of an aero-derivative gas turbogenerator and a heat recovery boiler. The total installed capacity at the plant is 17.5 MW. The project was first considered when the plant production capacity nearly tripled, thereby increasing the need for electrical energy. The cogeneration project, which went into production in December 1996 makes use of the considerable amounts of steam from the plants operation. There is also the possibility of wheeling electric energy to other plants owned by the same company. The authorities involved in the project are the Mexican Ministry of Energy, Comision Reguladora de Energia, Petroleos Mexicanos (which supplied the natural gas), Comision Federal de Electricidad, and other federal, state and local authorities. A review of the permits and contracts that made up the agreement was also included. 2 figs.

    Full Text Available A number of slopes that have been stable during many years may fail when an extraordinary rain period occurs. This phenomenon involves not only the lithology, the geometric and the mechanical characteristics of the slope but also the rain-evaporation-infiltration regime of the site. In this paper, the stability of a slope in the comunity of San Juan de Grijalva, Ostuacán, Chiapas (Mexico that failed during an intense raining period is analyzed. The volume of this slide was over 5 millions of cubics meters of soil and it produced the obstruction of the Grijalva river. The stratigraphic and geometric properties of the slope were determined and undisturbed samples were obtained in the site to determine the mechanical properties of the material. The stability analysis considered the variation of the cohesion of the soil caused by wetting and it was possible to observe the evolution of the safety factor with the water content of the material. Through the analysis of the rain infiltration and the stability of the slope, it has been possible to reproduce the failure process.

    The general climate of the island of Puerto Rico is dominated by the easterly trade winds from the Atlantic Ocean, and during synoptically calm days by the topographic and local land surface characteristics [1]. The urban canopy of the metropolitan area of San Juan, capital city of the Island, may introduce a new microclimate that changes the characteristics of the low atmosphere and interacts with the other microclimates already present in the island. The primitive land cover and land use (LCLU) of the metropolitan area of San Juan was composed by broadleaf trees, moist soils, and very dense vegetation in general. The urban LCLU changes the balance for the mass, momentum and energy between the bottom boundary and the lower atmosphere, creating different climate conditions over urban and rural regions. Some of these differences are low relative humidity and high temperatures observed in urban areas when compared to rural areas. These in turn produces a convective circulation over the urban areas, a phenomenon compared to the sea and land breezes, commonly known as heat islands (UHI). Factors that contribute to the formation of the UHI are anthropogenic heat sources, aerosols from pollutants, fast water canalization due to the presence of buildings and streets, among others. The comparison between urban and rural climates is the most common approach to analyze the UHI. These contrasts are larger in clear and calm conditions and tend to disappear in cloudy and windy weather. The UHI was recognized in the early 1950 s as closed isotherms that separates the city from the general temperature field [2]. The impact of the urban LCLU in San Juan, Puerto Rico, was quantified calculating the difference between historical data sets for the air temperature over an identified urban area and a rural area dT(U-R). The analysis of the climatological data revealed that a UHI exists in the metropolitan area of San Juan, Puerto Rico. The data reveals a permanent urban heat island

    The South Silverton mining area is immediately southeast of the town of Silverton, San Juan County, in southwestern Colorado (fig. 1). The town of Silverton itself lies in a relatively flat and open reach of the Animas Valley, called Bakers Park, in the western part of the San Juan Mountains. (See figs. 2 and 8.) The roughly circular area of the geologic map map (pl. 1) includes about 18½ square miles of the mountainous country southeast of Silverton. It is bounded on the west and north by the Animas River, on the east by Cunningham Creek, and on the south by Mountaineer Creek and Deer Park Creek. Altitudes range from 9,125 feet above sea level in the canyon of the Animas, at the southwest corner of the area, to 13,451 feet on Kendall Peak, 2¾ miles to the northeast.Within this area nearly a dozen horn-like peaks and sharp ridges separated by deep glacial cirques rise to altitudes of 13,000 feet or more. (See figs. 3, 7, 10, and 24.) Exposures are excellent along the crests and upper flanks of the ridges, but the bedrock along the lower parts of the valley walls and floors of the cirques is largely concealed by accumulations of talus. The timbered slopes along the south side of the Animas Valley are extensively covered with glacial moraine. Several of the high basins within the cirques hold ponds or small lakes; the largest is Silver Lake (fig. 23).Roads skirt the northern and eastern edges of the area but none give good access into the interior. Silverton is adjacent to U.S. Highway 550, which passes over the mountains by way of Red Mountain Pass from Ouray, 24 miles to the north, to Durango, 53 miles to the south. The community is also served by the narrow-gage line of the Denver and Rio Grande Western Railroad that follows the Animas River upstream from Durango. A gravel road, State Highway 110, follows the Animas River upstream, eastward from Silverton. From this highway a side road branches off to Cunningham Gulch as far as the Highland Mary mill, and

    Dengue fever (DF) is an important mosquito transmitted disease that is strongly influenced by meteorological and environmental conditions. Recent research has focused on forecasting DF case numbers based on meteorological data. However, these forecasting tools have generally relied on empirical models that require long DF time series to train. Additionally, their accuracy has been tested retrospectively, using past meteorological data. Consequently, the operational utility of the forecasts are still in question because the error associated with weather and climate forecasts are not reflected in the results. Using up-to-date weekly dengue case numbers for model parameterization and weather forecast data as meteorological input, we produced weekly forecasts of DF cases in San Juan, Puerto Rico. Each week, the past weeks' case counts were used to re-parameterize a process-based DF model driven with updated weather forecast data to generate forecasts of DF case numbers. Real-time weather forecast data was produced using the Weather Research and Forecasting (WRF) numerical weather prediction (NWP) system enhanced using additional high-resolution NASA satellite data. This methodology was conducted in a weekly iterative process with each DF forecast being evaluated using county-level DF cases reported by the Puerto Rico Department of Health. The one week DF forecasts were accurate especially considering the two sources of model error. First, weather forecasts were sometimes inaccurate and generally produced lower than observed temperatures. Second, the DF model was often overly influenced by the previous weeks DF case numbers, though this phenomenon could be lessened by increasing the number of simulations included in the forecast. Although these results are promising, we would like to develop a methodology to produce longer range forecasts so that public health workers can better prepare for dengue epidemics.

    Full Text Available The general behavior of the tourism sector in Puerto Rico, with its marked seasonality, hints at a close relationship between tourism activities and climate conditions. Even if weather condition is only one of many variables considered by travelling tourists, climate conditions weigh heavily in the majority of the decisions. The effect of climate variability on the environment could be manifested in warmer temperature, heat waves, and changes in the frequency of extreme weather events, such as severe storms and hurricanes, floods, and sea level rise. These conditions affect different sectors of society, among them public health and the economy. Therefore, our research has two main objectives: to establish a tourism climate index (TCI for Puerto Rico and to analyze if occupancy rates in hotels correspond to local weather conditions. Even though there are many other variables that could have positive or negative effects on tourism activities, results showed a significant association between occupancy rate in Puerto Rico and climate indexes. According to both TCI and the mean historical climate for tourism indexes, the most favorable months for tourism in Puerto Rico were February and March (winter, whereas the worst season was the end of August and the beginning of September (summer-fall. Although winter represents dry conditions and lower temperatures in San Juan, it also represents the highest occupancy rate during the years examined. In summer and fall, data showed high occupancy rates, yet climate conditions were not suitable; these months also correspond to the hurricane season. During this season, high relative occupancy rates responded to internal and local tourism patterns. It can therefore be assumed that until the climate-tourism relationship is well characterized, there is little hope of fully understanding the potential economic effects, detrimental or beneficial, of global climate change, not only on tourism in Puerto Rico, but on

  14. Inter- and Intraspecific Variations of Bacterial Communities Associated with Marine Sponges from San Juan Island, Washington

    This study attempted to assess whether conspecific or congeneric sponges around San Juan Island, Washington, harbor specific bacterial communities. We used a combination of culture-independent DNA fingerprinting techniques (terminal restriction fragment length polymorphism and denaturing gradient gel electrophoresis [DGGE]) and culture-dependent approaches. The results indicated that the bacterial communities in the water column consisted of more diverse bacterial ribotypes than and were drastically different from those associated with the sponges. High levels of similarity in sponge-associated bacterial communities were found only in Myxilla incrustans and Haliclona rufescens, while the bacterial communities in Halichondria panicea varied substantially among sites. Certain terminal restriction fragments or DGGE bands were consistently obtained for different individuals of M. incrustans and H. rufescens collected from different sites, suggesting that there are stable or even specific associations of certain bacteria in these two sponges. However, no specific bacterial associations were found for H. panicea or for any one sponge genus. Sequencing of nine DGGE bands resulted in recovery of seven sequences that best matched the sequences of uncultured Proteobacteria. Three of these sequences fell into the sponge-specific sequence clusters previously suggested. An uncultured alphaproteobacterium and a culturable Bacillus sp. were found exclusively in all M. incrustans sponges, while an uncultured gammaproteobacterium was unique to H. rufescens. In contrast, the cultivation approach indicated that sponges contained a large proportion of Firmicutes, especially Bacillus, and revealed large variations in the culturable bacterial communities associated with congeneric and conspecific sponges. This study revealed sponge species-specific but not genus- or site-specific associations between sponges and bacterial communities and emphasized the importance of using a combination

  4. [The examination of men's wits by Juan Huarte de San Juan, and the dawn of the neurobiology of intelligence in the Spanish renaissance].

    Science.gov (United States)

    Martín-Araguz, A; Bustamante-Martínez, C

    The Spanish renaissance doctor Juan Huarte de San Juan (1529-1588) was the author of a unique and immortal work, The Examination of Men's Wits, the edition princeps of which was printed in Baeza in 1575. Since then it has been reprinted at least 80 times and translated into seven languages, which makes it the most influential Spanish contribution to medicine ever published. In this paper we review the unjustly little-known figure of Huarte as the founder of Neuropsychology, and we also analyse his works from a historical and neuroscientific point of view. Huarte's writings deal with the problem of the organic relations between the brain and understanding, and accept the possible influences exerted by temper on the will within the field of the Neurobiology of Intelligence. Thus, over four centuries ago Huarte became the founder of Differential or Physiological Psychology, Neuropsychology, Eugenics and Career Guidance. Huarte's work not only played a fundamental role in the history and development of the body of neuroscientific knowledge, but has also been a clear (although not always cited) influence on scientists, philosophers and men of letters such as Alarcón, Bacon, Cabanis, Cervantes (whose Don Quixote was inspired by him), Charron, Chomsky, Gall, Goethe, Hume, Kant, Kretchmer, Lessing, Lope de Vega, Montaigne, Montesquieu, Nietzsche, Quevedo, Rousseau, Schopenhauer, Thomasius, Tirso de Molina and Ziegler. In the middle of the 16th century, Huarte and his Examination of Men's Wits, together with the works of the naturalist philosophers Gómez Pereira (Antoniana Margarita, 1554) and Miguel Sabuco (New Philosophy, 1587), constituted the prestigious triumvirate of Spanish Renaissance scholars who, for the first time in history, contemplated the workings of the brain from a point of view that had more to do with science than the supernatural.

    On the basis of geologic assessment, the natural gas in place in the Fruitland Formation coals of the San Juan Basin is estimated at 50 trillion cubic feet. The north-central portion of San Juan Basin contains the highest concentrations of coalbed methane for the Fruitland Formation coals. The area coincides with the thick deposits of high-rank coals. To provide a foundation for evaluating the coalbed methane in place on a township-by-township basis, the study delineates the subsurface geology of the Fruitland Formation coals. Four regional cross sections and detailed overburden, net coal isopach, and coal rank maps are included.

    The White Canyon area in San Juan County, Utah, contains known deposits of copper-uranium ore and is currently being mapped and studied by the Geological Survey. To date, approximately 75 square miles, or about 20 percent of the area, has been mapped on a scale 1 inch=1 mile. The White Canyon area is underlain by more than 2,000 feet of sedimentary rocks, Carboniferous to Jurassic(?) in age. The area is on the flank of the Elk Ridge anticline, and the strata have a regional dip of 1 deg to 2 deg SW. The Shinarump conglomerate of Late Triassic age is the principal ore-bearing formation. The Shinarump consists of lenticular beds of sandstone, conglomeratic sandstone, clay, and siltstone, and ranges in thickness from a feather edge to as much as 75 feet. Locally the sandstones contain silicified and carbonized wood and fragments of charcoal. These vegetal remains are especially common in channel-fill deposits. Jointing is prominent in the western part of the area, and apparently affects all formations. Adjacent to the joints some of the redbeds in the sequence are bleached. Deposits of copper-uranium minerals have been found in the Moenkopi, Shinarump, and Chinle formations, but the only production of ore has been from the Shinarump conglomerate. The largest concentration of these minerals is in the lower third of the Shinarump, and the deposits seem to be controlled in part by ancient channel fills and in part by fractures. Locally precipitation of the copper and uranium minerals apparently has been aided by charcoal and clays. Visible uranium minerals include both hard and soft pitchblende and secondary hydrosulfates, phosphates, and silicates. In addition, unidentified uranium compounds are present in carbonized wood and charcoal, and in veinlets of hydrocarbons. Base-metal sulfides have been identified in all prospects that extend beyond the oxidized zone. Secondary copper minerals in the oxidized zone include the hydrous sulfates and carbonates, and possibly

    The San Juan volcanic field comprises 25,000 km2 of intermediate composition mid-Tertiary volcanic rocks and dacitic to rhyolitic calderas including the San Juan–Uncompahgre and La Garita caldera-forming super-volcanoes. The region is famous for the geological, ecological, hydrological, archeological, and climatological diversity. These characteristics supported ancestral Puebloan populations. The area is also important for its mineral wealth that once fueled local economic vitality. Today, mitigating and/or investigating the impacts of mining and establishing the region as a climate base station are the focuses of ongoing research. Studies include advanced water treatment, the acid neutralizing capacity (ANC) of propylitic bedrock for use in mine-lands cleanup, and the use of soil amendments including biochar from beetle-kill pines. Biochar aids soil productivity and revegetation by incorporation into soils to improve moisture retention, reduce erosion, and support the natural terrestrial carbon sequestration (NTS) potential of volcanic soils to help offset atmospheric CO2 emissions. This field trip will examine the volcano-tectonic and cultural history of the San Juan volcanic field as well as its geologic structures, economic mineral deposits and impacts, recent mitigation measures, and associated climate research. Field trip stops will include a visit to (1) the Summitville Superfund site to explore quartz alunite-Au mineralization, and associated alteration and new water-quality mitigation strategies; (2) the historic Creede epithermal-polymetallic–vein district with remarkably preserved resurgent calderas, keystone-graben, and moat sediments; (3) the historic mining town of Silverton located in the nested San Juan–Silverton caldera complex that exhibits base-metal Au-Ag mineralization; and (4) the site of ANC and NTS studies. En route back to Denver, we will traverse Grand Mesa, a high NTS area with Neogene basalt-derived soils and will enjoy a soak

    The Southwestern Regional Partnership on CO2 Sequestration conducted an Enhanced Coalbed Methane (ECBM)/Carbon Storage Pilot in the San Juan Basin as part of the ongoing DOE/NETL Carbon Capture and Storage Program. The primary goal of this pilot is to demonstrate the efficacy of using CO2 to enhance coalbed methane recovery particularly near reservoir abandonment pressure while also evaluating the suitability of coal seams for longer-term carbon storage. Basic geologic models of the coal seams were developed from well logs in the area. Production histories from several surrounding CBM wells were shown. To monitor the injection of up to 75,000 ton of CO2 beginning September 2007, seismic surveys and tiltmeter arrays were utilized. Larger-scale geo-hydrodynamic simulations were used to develop a regional model for the fluid dynamics of the northern San Juan Basin. Smaller-scale reservoir simulations, incorporating available laboratory and field data, were used to develop an improved understanding of reservoir dynamics within the specific 640-acre pilot area. Both modeling scales were critical to assessing the suitability of deploying commercial carbon storage programs throughout the basin. Reservoir characterization results on the optimization of total CO2 injection volume, injection rate over time, and how CO2 is expected to disperse after injection are presented. This is an abstract of a paper presented at the 2007 AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).

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

Ese honor le corresponde al Hospital de Santiago, que fue fundado el 28 de diciembre de 1513 en la ciudad de Santa María la Antigua del Darien, por el conquistador Pedrarias Dávila, en cumplimiento de una Cédula Real dirigida a la Casa de Contratación de Sevilla en agosto del mismo año, mediante la cual el Rey don Fernando el Católico ordena “que se haga en el pueblo de la provincia de Santa María la Antigua del Darien que es la tierra firme, un hospital donde se acojan e curen los enfermos e abriguen los pobres e convendra proveer el dicho Hospital de algunas camas e otras cosas…. Yo os mando, agrega el Rey, que compréis cincuenta camas de ropa en las que haya en cada una de ellas el aparejo que suelen tener las camas de esta ciudad de Sevilla”.

    El pequeño poblado de Santa María la Antigua del Darien había sido fundado por Vasco Núñez de Balboa en 1509, en tierras del cacique Cenaco, y adquirió la categoria de ciudad por Cédula Real del 10 de julio de 1515. El Hospital de Santiago contó como personal médico con Rodrigo de Barreda, quien gozaba de buena reputación médica y científica, con el bachiller Diego de Angulo, y con el maestre Alonso de Santiago, quien había atendido al conquistador Alonso de Ojeda en 1510 de un flechazo que le atravezó el muslo. Pensando que la herida pudiera estar envenenada, Ojeda ordenó a Santiago que calentase al rojo blanco dos planchas de hierro para que se las colocase en la herida.

    Como el maestre se mostrara temeroso de hacerlo temiendo que podría causarle la muerte, Ojeda le dijo que si se negaba lo haría ahorcar, ante lo cual el cirujano procedió a aplicarle el tratamiento, “con ciertas tenazas, dice el padre Las Casas, de modo que no sólo le abrasó el muslo y la

    Drenth, Benjamin John

    This dissertation includes three separate chapters, each demonstrating the interpretive utility of potential field (gravity and magnetic) geophysical datasets at various scales and in various geologic environments. The locations of these studies are the central San Luis Basin of Colorado and New Mexico, the San Juan Mountains of southwestern Colorado, and southern and western Afghanistan. The San Luis Basin is the northernmost of the major basins that make up the Rio Grande rift, and interpretation of gravity and aeromagnetic data reveals patterns of rifting, rift-sediment thicknesses, distribution of pre-rift volcanic and sedimentary rocks, and distribution of syn-rift volcanic rocks. Syn-rift Santa Fe Group sediments have a maximum thickness of ˜2 km in the Sanchez graben near the eastern margin of the basin along the central Sangre de Cristo fault zone. Under the Costilla Plains, thickness of these sediments is estimated to reach ˜1.3 km. The Santa Fe Group sediments also reach a thickness of nearly 1 km within the Monte Vista graben near the western basin margin along the San Juan Mountains. A narrow, north-south-trending structural high beneath San Pedro Mesa separates the graben from the structural depression beneath the Costilla Plains. Aeromagnetic anomalies are interpreted to mainly reflect variations of remanent magnetic polarity and burial depth of the 5.3-3.7 Ma Servilleta basalt of the Taos Plateau volcanic field. Magnetic-source depth estimates indicate patterns of subsidence following eruption of the basalt and show that the Sanchez graben has been the site of maximum subsidence. One of the largest and most pronounced gravity lows in North America lies over the rugged San Juan Mountains in southwestern Colorado. A buried, low-density silicic batholith related to an Oligocene volcanic field coincident with the San Juan Mountains has been the accepted interpretation of the source of the gravity low since the 1970s. However, this interpretation was

    This report is one in a series resulting from the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) study of the San Juan structural basin that began in October 1984. Previous reports in the series describe the hydrogeology of the Dakota Sandstone (Craigg and others, 1989), Morrison Formation (Dam and others, 1990), Gallup Sandstone (Kernodle and others, 1989), Menefee Formation (Levings and others, 1990), and Cliff House Sandstone (Thorn and others, 1990), in the San Juan structural basin. The purposes of the RASA (Welder, 1986) are to: (1) Define and evaluate the aquifer system; (2) assess the effects of past, present, and potential ground-water use on aquifers and streams; and (3) determine the availability and quality of ground water. This report summarizes information on the geology and the occurrence and quality of water in the Point Lookout Sandstone, one of the primary water-bearing units in the regional aquifer system. Data used in this report were collected during the study or were derived from existing records in the U.S. Geological Survey's computerized National Water Information System (NWIS) data base, the Petroleum Information Corporation's database, and the Dwight's ENERGYDATA Inc. BRIN data base. Although all data available for the Point Lookout Sandstone were considered in formulating the discussions in the text, not all those data could be plotted on the illustrations. The San Juan structural basin is in New Mexico, Colorado, Arizona, and Utah and has an area of about 21,600 square miles (fig. 1). The structural basin is about 140 miles wide and about 200 miles long. The study area is that part of the structural basin that contains rocks of Triassic or younger age and, therefore, is less areally extensive than the structural basin. Triassic through Tertiary sedimentary rocks are emphasized in this study because the major aquifers in the basin are present in these rocks.

    2012-01-01

    Based on U-Pb dating of two dinosaur bones from the San Juan Basin of New Mexico (United States), Fassett et al. (2011) claim to provide the first successful direct dating of fossil bones and to establish the presence of Paleocene dinosaurs. Fassett et al. ignore previously published work that directly questions their stratigraphic interpretations (Lucas et al., 2009), and fail to provide sufficient descriptions of instrumental, geochronological, and statistical treatments of the data to allow evaluation of the potentially complex diagenetic and recrystallization history of bone. These shortcomings lead us to question the validity of the U-Pb dates published by Fassett et al. and their conclusions regarding the existence of Paleocene dinosaurs.

    2014-06-01

    Full Text Available Climate variability is a threat to water resources on a global scale and in tropical regions in particular. Rainfall events and patterns are associated worldwide with natural disasters like mudslides and landslides, meteorological phenomena like hurricanes, risks/hazards including severe storms and flooding, and health effects like vector-borne and waterborne diseases. Therefore, in the context of global change, research on rainfall patterns and their variations presents a challenge to the scientific community. The main objective of this research was to analyze recent trends in precipitation in the San Juan metropolitan area in Puerto Rico and their relationship with regional and global climate variations. The statistical trend analysis of precipitation was performed with the nonparametric Mann-Kendall test. All stations showed positive trends of increasing annual rainfall between 1955 and 2009. The winter months of January and February had an increase in monthly rainfall, although winter is normally a dry season on the island. Regarding dry days, we found an annual decreasing trend, also specifically in winter. In terms of numbers of severe rainfall events described as more than 78 mm in 24 hours, 63 episodes have occurred in the San Juan area in the last decade, specifically in the 2000-2009 time frame, with an average of 6 severe events per year. The majority of the episodes occurred in summer, more frequently in August and September. These results can be seen as a clear example of the complexity of spatial and temporal of rainfall distribution over a tropical city.

  7. How Frequently Can a "Supervolcano" Erupt? Rapid Emplacement of Voluminous Compositionally Diverse Ignimbrites, Central San Juan Calderas, Colorado

    Lipman, P. W.; McIntosh, W. C.

    2006-12-01

    High-resolution single-crystal laser-fusion 40Ar/39Ar age determinations on sanidine phenocrysts document sequential eruption of four multi-hundred cubic-kilometer ignimbrites and associated lavas flows from calderas in the central San Juan Mountains, Colorado within a cumulative time interval of less than 50-100 ka. The tight recurrence interval was not evident from previous incremental-heating 40Ar/39Ar plateau ages, which were stratigraphically inconsistent on time scales beyond analytical precision. The new single- crystal results show that three tuff sheets, Rat Creek (>150 km3), Cebolla Creek (>250 km3), and Nelson Mountain Tuffs Creek (>500 km3) from spatially overlapping sources in the San Luis- Cochetopa caldera complex, erupted between 26.92±0.05 and 26.91±0.03 Ma (9 separate samples). A sequence of four postcollapse lavas at Cochetopa erupted at 26.86±0.04 Ma (6 samples) while an andesitic stratocone grew within San Luis caldera complex. Concurrently, Snowshoe Mountain Tuff (>500 km3) erupted from the Creede caldera, 20 km to the south, at 26.87±0.05 Ma (5 samples). Within this limited time interval, eruptive compositions fluctuated widely. Rat Creek and Nelson Mountain Tuffs are compositionally zoned from crystal-poor low-Si rhyolite to cpx-bearing dacite, while the intervening Cebolla Creek Tuff is uniform mafic hbl-rich dacite. Cochetopa Dome lavas are nearly aphyric high-Si rhyolite, while Snowshoe Mountain Tuff is crystal-rich low-Si cpx-bearing dacite. For comparison, four ignimbrites from Aso caldera in southern Japan, with a cumulative volume of ~300 km3, erupted at 270, 140, 120, and 90 ka (Nakada et al., 2003); four overlapping caldera collapses at Santorini in the Aegean were each associated with silicic tuff with volumes of several tens of kilometers, at 203, ~100, 21, and 3.6 ka (Druitt, 1999). In contrast, larger "supervolcano" systems, such as Yellowstone, commonly have repose periods of 0.5- 1x106 m.y., even when eruptive compositions

    Full Text Available Las Fiestas de la Calle de San Sebastián is a four day-long festival in San Juan, Puerto Rico. While the festival comprises music and dance that is a combination of various Caribbean and Latin American aesthetics, there is a small group of local musicians who insist on staying away from the larger throngs to specifically play a Puerto Rican music medium known as plena. By defining a distinct physical space that is separate from the rest of the festival, but also a part of the festival, they sing throughout the night speaking to contemporary issues of American imperialism, class warfare, and corrupt politicians. During the festival the complex power dynamics of Puerto Rico as a United States territory, lacking both independence as a sovereign nation and the same rights as a state, are manifested in festival performance. This performance tries to negotiate how the island remains autonomous while being attached to a more powerful mainland economy.

    The San Juan structural basin is an 18,000 sq mi area that contains several extensive aquifers. The basin includes three surface drainage basins and parts of New Mexico, Colorado, Arizona, and Utah. Surface water in the area is fully appropriated, and the steadily increasing demand for groundwater has resulted in water supply concerns. Competition is great between mining and electric power companies, municipalities, and Indian communities for the limited groundwater supplies. This report outlines a 4-year plan for a study of the regional aquifer system in the San Juan structural basin. The purposes of the study are to define and understand the aquifer system; to assess the effects of groundwater use on the aquifers and streams; and to determine the availability and quality of groundwater in the basin.

The purposes of the study (Welder, 1986) are to: (1) Define and evaluate the aquifer system; (2) assess the effects of past, present, and potential ground-water use on aquifers and streams, and (3) determine the availability and quality of ground water. Previous reports in this series describe the hydrogeology of the Dakota Sandstone (Craigg and others, 1989), Gallup Sandstone (Kernodle and others, 1989), Morrison Formation (Dam and others, 1990), Point Lookout Sandstone (Craigg and others, 1990), Kirtland Shale and Fruitland Formation (Kernodle and others, 1990), Menefee Formation (Levings and others, 1990), Cliff House Sandstone (Thorn and others, 1990), and Ojo Alamo Sandstone (Thorn and others, 1990) in the San Juan structural basin. This report summarizes information on the geology and the occurrence and quality of water in the Pictured Cliffs Sandstone, one of the primary water-bearing units in the regional aquifer system.

    Twenty-five new 40Ar/39Ar ages from volcanic rocks and veins in the western San Juan Mountains clarify relationships between volcanism and mineralization in this classic area. Five calc-alkaline ash-flow sheets erupted from caldera sources (Ute Ridge, Blue Mesa, Dillon Mesa, Sapinero Mesa, and Crystal Lake Tuffs) from 28.6 to 27.6 Ma. This is a much more restricted time interval than previously thought and indicates that the underlying batholith rose and evolved very rapidly beneath the western San Juan Mountains. The new ages and geologic relations constrain the timing of joint resurgence of the Uncompahgre and San Juan calderas to between 28.2 and 27.6 Ma. The collapse of the Silverton caldera produced a set of strong ring fractures that intersected with graben faults on the earlier resurgent dome to produce the complex set of structures that localized the mid-Miocene epithermal gold veins. Later calc-alkaline monzonitic to quartz monzontic plutons solidified at 26.5-26.0 Ma as the underlying batholith rose through its volcanic cover. A new age from lavas near Uncompahgre Peak supports earlier interpretations that these lavas were fed by nearby 26 Ma monzonite intrusions. Nearly all of these intrusions are associated with subeconomic Mo and Cu mineralization and associated alteration, and new ages of 26.40 and 25.29 Ma from the Ute-Ulay and Lilly veins in the Lake City region show that some of the most important silver and base-metal veins were temporally and possibly genetically connected to these plutons. In addition, the Golden Fleece telluride vein cuts all of the post-Uncompahgre caldera volcanics in the area and is probably temporally related to this cycle, though its age of 27.5 ? 0.3 Ma was determined by less precise U/Pb methods. The 22.9 Ma Lake City caldera collapsed within the older Uncompahgre caldera structure but is petrologically unrelated to the older calc-alkaline activity. The distinctive suite of high-silica rhyolite tuff and alkaline

Three species were collected: the cestodes Dipylidium caninum (Linnaeus, 1758 Railliet, 1892 and Taenia pisiformis (Bloch, 1780 and the nematode Toxocara canis (Werner, 1782 Stiles, 1905. Fifty per cent of the examined dogs showed one or two parasites. A total of 303 (0-116 helminths were recovered and the intensity of infection was 30,3. The Simpson index (C for all parasite species was 0,414, indicating a dominance by one species in the parasite community. The mean diversity in the infracommunities of C. familiaris was H' = 0,038 and uniformity index of Pielou J = 0,207. Dipylidium caninum, T. pisiformis, and T. canis presented a prevalence of infection of 33,30%, 10% and 16,6% respectively. Dipylidium caninum presented the highest frequency and mean intensity of infection. Dipylidium caninum was the helminth with the highest dominance (94% whereas the lowest was due to T. pisiformis (4% and T. canis (2%. Helminths were not related to the age of the hosts, prevalence and mean intensity of infection. Out of the 10 equally divided segments of the intestinal gut, D. caninum was found from the 6th to the 9th segment. T canis preferred almost exclusively the 1st segment while T. pisiformis was randomly distributed.

    Large, explosive volcanic eruptions can have both immediate and long-term negative effects on human societies. Statistical analyses of volcanic eruptions show that the frequency of the largest eruptions on Earth (> ˜450 km3) differs from that observed for smaller eruptions, suggesting different physical processes leading to eruption. This project will characterize the petrography, whole-rock geochemistry, mineral chemistry, and zircon geochronology of four caldera-forming ignimbrites from the San Juan caldera cluster, Colorado, to determine the physical processes leading to eruption. We collected outflow samples along stratigraphy of the three caldera-forming ignimbrites of the San Luis caldera complex: the Nelson Mountain Tuff (>500 km3), Cebolla Creek Tuff (˜250 km3), and Rat Creek Tuff (˜150 km3); and we collected samples of both outflow and intracaldera facies of the Snowshoe Mountain Tuff (>500 km3), which formed the Creede caldera. Single-crystal sanidine 40Ar/39Ar ages show that these eruptions occurred in rapid succession between 26.91 ± 0.02 Ma (Rat Creek) and 26.87 ± 0.02 Ma (Snowshoe Mountain), providing a unique opportunity to investigate the physical processes leading to a rapid sequence of large, explosive volcanic eruptions. Recent studies show that the average flux of magma is an important parameter in determining the frequency and magnitude of volcanic eruptions. High-precision isotope-dilution thermal ionization mass spectrometry (ID-TIMS) zircon geochronology will be performed to determine magma fluxes, and cross-correlation of chemical profiles in minerals will be performed to determine the periodicity of magma recharge that preceded these eruptions. Our project intends to combine these findings with similar data from other volcanic regions around the world to identify physical processes controlling the regional and global frequency-magnitude relationships of volcanic eruptions.

    Previous studies on the influence of weather on Aedes aegypti dynamics in Puerto Rico suggested that rainfall was a significant driver of immature mosquito populations and dengue incidence, but mostly in the drier areas of the island. We conducted a longitudinal study of Ae. aegypti in two neighborhoods of the metropolitan area of San Juan city, Puerto Rico where rainfall is more uniformly distributed throughout the year. We assessed the impacts of rainfall, temperature, and human activities on the temporal dynamics of adult Ae. aegypti and oviposition. Changes in adult mosquitoes were monitored with BG-Sentinel traps and oviposition activity with CDC enhanced ovitraps. Pupal surveys were conducted during the drier and wetter parts of the year in both neighborhoods to determine the contribution of humans and rains to mosquito production. Mosquito dynamics in each neighborhood was compared with dengue incidence in their respective municipalities during the study. Our results showed that: 1. Most pupae were produced in containers managed by people, which explains the prevalence of adult mosquitoes at times when rainfall was scant; 2. Water meters were documented for the first time as productive habitats for Ae. aegypti; 3. Even though Puerto Rico has a reliable supply of tap water and an active tire recycling program, water storage containers and discarded tires were important mosquito producers; 4. Peaks in mosquito density preceded maximum dengue incidence; and 5. Ae. aegypti dynamics were driven by weather and human activity and oviposition was significantly correlated with dengue incidence.

    A description of a cogeneration plant in San Juan del Rio, Mexico was presented. The Arancia-Corn Products, S.A. de C.V. corn processing plant makes use of an aero-derivative gas turbogenerator and a heat recovery boiler. The total installed capacity at the plant is 17.5 MW. The project was first considered when the plant production capacity nearly tripled, thereby increasing the need for electrical energy. The cogeneration project, which went into production in December 1996 makes use of the considerable amounts of steam from the plants operation. There is also the possibility of wheeling electric energy to other plants owned by the same company. The authorities involved in the project are the Mexican Ministry of Energy, Comision Reguladora de Energia, Petroleos Mexicanos (which supplied the natural gas), Comision Federal de Electricidad, and other federal, state and local authorities. A review of the permits and contracts that made up the agreement was also included. 2 figs.

    This geoarcheological study investigates soil stratigraphy and geochronology of alluvial deposits to determine Holocene landscape evolution within the Hot Creek, La Jara Creek, and Alamosa River drainage basins in the San Juan Mountains of Colorado. Geomorphic mapping and radiocarbon dating indicate synchronicity in patterns of erosion, deposition, and stability between drainage basins. In all three basins, the maximum age of mapped alluvial terraces and fans is ~ 3300 cal yr BP. A depositional period seen at both Hot Creek and the Alamosa River begins ~ 3300 to 3200 cal yr BP. Based on soil development, short periods of stability followed by alluvial fan aggradation occur in the Alamosa River basin ~ 2200 cal yr BP. A period of landscape stability at Hot Creek before ~ 1100 cal yr BP is followed by a period of rapid aggradation within all three drainages between ~ 1100 and 850 cal yr BP. A final aggradation event occurred between ~ 630 and 520 cal yr BP at La Jara Creek. These patterns of landscape evolution over the past ~ 3300 yr provide the framework for an archeological model that predicts the potential for buried and surficial cultural materials in the research area.

    Full Text Available Carbon dioxide (CO2 is considered one of the most important greenhouse gases in the study of climate change. CO2 adsorption was studied using the gas chromatography technique, while the Freundlich and Langmuir adsorption models were employed for processing isotherm data in the temperature range of 473–573 K. The isosteric heat of adsorption was calculated from the Clausius–Clapeyron equation. Moreover, the thermodynamic properties ΔG, ΔU, and ΔS were evaluated from the adsorption isotherms of Langmuir using the Van’t Hoff Equation. The four soil samples were recollected from San Juan Amecac, Puebla, Mexico, and their morphologies were investigated through X-ray diffraction (XRD and N2 adsorption at 77 K. The SJA4 soil has a crystalline Kaolinite phase, which is one of its non-metallic raw materials, and N2 isotherms allowed for the determination of pore size distributions and specific surface areas of soil samples. The Barrett–Joyner–Halenda (BJH distribution of pore diameters was bimodal with peaks at 1.04 and 3.7 nm, respectively. CO2 adsorption showed that the SJA1 soil afforded a higher amount of adsorbed CO2 in the temperature range from 453 to 573 K followed by SJA4 and finally SJA2, classifying this process as exothermic physisorption.

    The coal-bearing Upper Cretaceous Fruitland Formation occupies an area of about 14 square miles in the extreme southeast corner of the Ute Mountain Ute Indian Reservation in San Juan County, New Mexico. In this area, the Fruitland Formation contains an estimated 252 million short tons of coal in beds that range from 1.2 to 14 feet thick. About 100 million short tons of coal occur under less than 500 feet of overburden in the Ute Canyon, Upper Main, and Main coal beds. These three coal beds reach a cumulative coal thickness of about 18 feet in a stratigraphic interval that averages about 120 feet thick in the prospecting permit area, which is located in the extreme southwestern part of the study area. The southwestern part of the study area is probably best suited for surface mining, although steep dips may reduce minability locally. A major haul road that was recently constructed across the eastern half of the study area greatly improves the potential for surface mining. Core sample analyses indicate that the apparent rank of the Ute Canyon, Upper Main, and Main coal beds is high-volatile C bituminous. Average heat-of-combustion on an as-received basis is 10,250 British thermal units per pound, average ash content is 15.5 percent, and average sulfur content is 1.0 percent.

    Ore in the La Sal mine, San Juan County, Utah, occurs as a typical tabular-type uranium deposit of the-Colorado Plateau. Uranium-vanadium occurs in the Salt Wash Member of the Jurassic Morrison Formation. Chemical and petrographic analyses were used to determine elemental variation and diagenetic aspects across the orebody. Vanadium is concentrated in the dark clay matrix, which constitutes visible ore. Uranium content is greater above the vanadium zone. Calcium, carbonate carbon, and lead show greater than fifty-fold increase across the ore zone, whereas copper and organic carbon show only a several-fold increase. Large molybdenum concentrations are present in and above the tabular layer, and large selenium concentrations occur below the uranium zone within the richest vanadium zone. Iron is enriched in the vanadium horizon. Chromium is depleted from above the ore and strongly enriched below. Elements that vary directly with the vanadium content include magnesium, iron, selenium, zirconium, strontium, titanium, lead, boron, yttrium, and scandium. The diagenetic sequence is as follows: (1) formation of secondary quartz overgrowths as cement; (2) infilling and lining of remaining pores with amber opaline material; (3) formation of vanadium-rich clay matrix, which has replaced overgrowths as well as quartz grains; (4) replacement of overgrowths and detrital grains by calcite; (5) infilling of pores with barite and the introduction of pyrite and marcasite.

    Full Text Available OBJECTIVE: To identify socio-demographic, behavioral, and health-related correlates of food preferences in Puerto Rico that will help determine Caribbean-region populations vulnerable to nutrition transition. METHODS: Data from a cross-sectional study of a representative sample of 858 adults residing in the San Juan Metropolitan Area of Puerto Rico were analyzed. Multivariable ordinal logistic regressions were used to model the frequency of consumption of 1 fruits and vegetables, 2 tubers/starchy root vegetables, 3 fried foods, and 4 Western-style fast foods as a function of socio-demographic, behavioral, and health-related characteristics. RESULTS: Higher frequency of consumption of fruits and vegetables was associated with being physically active and older and having a medium to high level of education, whereas intake of tubers was associated with being older, having a low income, not using government insurance, and having elevated levels of triglycerides. Frequency of consumption of fast food was associated with younger age, higher income, 12-15 years of formal education, and a higher body mass index (BMI, whereas frequency of consumption of fried food was associated with being younger and male, not being a smoker, and having elevated levels of fasting blood glucose. CONCLUSIONS: The results indicate a nutrition transition in Puerto Rico with health consequences for the Caribbean region. The characteristics of this nutrition transition seem to be determined by income, education, and age, but may also be dictated by access to various food groups. These results set the stage for needed investigation of environmental and individual-level factors that could shape patterns in food consumption.

    Although children living in Puerto Rico have the highest asthma prevalence of all US children, little is known regarding the quality-of-care disparities they experience nor the adaptability of existing asthma evidence-based interventions to reduce these disparities. The objective of this study was to describe our experience in reducing quality-of-care disparities among Puerto Rican children with asthma by adapting 2 existing evidence-based asthma interventions. We describe our experience in adapting and implementing 2 previously tested asthma evidence-based interventions: the Yes We Can program and the Inner-City Asthma Study intervention. We assessed the feasibility of combining key components of the 2 interventions to reduce asthma symptoms and estimated the potential cost savings associated with reductions in asthma-related hospitalizations and emergency department visits. A total of 117 children with moderate and severe asthma participated in the 12-month intervention in 2 housing projects in San Juan, Puerto Rico. A community-academic team with the necessary technical and cultural competences adapted and implemented the intervention. Our case study revealed the feasibility of implementing the combined intervention, henceforth referred to as La Red intervention, in the selected Puerto Rican communities experiencing a disproportionately high level of asthma burden. After 1-year follow-up, La Red intervention significantly reduced asthma symptoms and exceeded reductions of the original interventions. Asthma-related hospitalizations and emergency department use, and their associated high costs, were also significantly reduced. Asthma evidence-based interventions can be adapted to improve quality of care for children with asthma in a different cultural community setting.

    The Peruvian population of the South American fur seal ( Arctocephalus australis ) is a distinct evolutionarily significant unit that is endangered. One of the largest rookeries for this species in Peru is located within the Punta San Juan marine protected area (15°22'S, 75°12'W). To better understand the current health status of this population, exposure to 10 pinniped pathogens was evaluated in adult female fur seals (n=29) via serology and polymerase chain reaction (PCR) techniques in November 2010. The results suggest this population is naïve to canine and phocine distemper viruses (serum neutralization test), five Leptospira interrogans serovars (microscopic agglutination test), and Brucella canis (card test). Indirect fluorescent antibody testing for Toxoplasma gondii , Neospora caninum , and Sarcocystis neurona was also uniformly negative. PCR testing of nasal swabs using previously described Mycoplasma spp. primers was positive in 37.9% (11/29) of samples. One animal was positive via card test for Brucella abortus , whereas 53.7% (15/28) were positive or suspect using a marine Brucella competitive enzyme-linked immunosorbent assay. Antibody to phocine herpesvirus-1 (PHV-1) was identified in 85.7% (24/28) of the sampled population by serum neutralization testing. Overall, exposure to Mycoplasma spp., Brucella spp., and PHV-1 was observed, but results demonstrated low to no exposure to many key pinniped pathogens. The expansion of human populations, agriculture, and industry along the Peruvian coast may lead to increased pathogen exposure from human, domestic, and wild animal sources. The naïve nature of this key population of South American fur seals raises concerns about potential risk for disease outbreaks.

    The Río Piedras is the only River in the metropolitan area of Puerto Rico. This River was the first water supplier and is part of the ancient aqueduct, the first treatment plant of the San Juan urban area. Because of its cultural and historic importance the ancient aqueduct was cataloged as a National Treasure by the National Trust of History Preservation in 2014. Actually, is protected by Para La Naturaleza (before named in Spanish as the "Fideicomiso de Conservación de Puerto Rico"). The research objectives were to evaluate and measure the dissolved oxygen (DO), total phosphorus (TP) and the heavy metals (HM) concentrations of the River. Also, to examine if the DO, TP and HM (Cu, Fe, Pb, Mn, Al, and Zn) concentrations were in compliance with the Environmental Protection Agency (EPA) standards. Using DO bottles, water samples were collected on three points during six dates. DO concentrations were measured with the YSI Pro GBOD. TP concentrations were analyzed using the UV-Vis spectrophotometer "HACH" (DR 5000). Utilizing the ICP (Inductively Coupled Plasma) spectrophotometer emission technique and the EPA protocols HM concentrations were measured. Preliminary results show that the DO measurements were from 5.00 mg/L to 7.00 mg/L (p-value=0.282). HM concentrations findings were 0.456 (correlation coefficient=0.9997), 1.205 (correlation coefficient=0.9972) and 3.287 (correlation coefficient=0.9950) for Zn, Cu and Cr, respectively. We expected highest HM concentrations in our finals results due to the drought weather during each samples collection. Data analysis for DO, TP and HM concentrations will be presented. Finally, the results obtained and the project details will be explained during the poster presentation.

    Studying the evolution and biogeographic distribution of dinosaurs during the latest Cretaceous is critical for better understanding the end-Cretaceous extinction event that killed off all non-avian dinosaurs. Western North America contains among the best records of Late Cretaceous terrestrial vertebrates in the world, but is biased against small-bodied dinosaurs. Isolated teeth are the primary evidence for understanding the diversity and evolution of small-bodied theropod dinosaurs during the Late Cretaceous, but few such specimens have been well documented from outside of the northern Rockies, making it difficult to assess Late Cretaceous dinosaur diversity and biogeographic patterns. We describe small theropod teeth from the San Juan Basin of northwestern New Mexico. These specimens were collected from strata spanning Santonian - Maastrichtian. We grouped isolated theropod teeth into several morphotypes, which we assigned to higher-level theropod clades based on possession of phylogenetic synapomorphies. We then used principal components analysis and discriminant function analyses to gauge whether the San Juan Basin teeth overlap with, or are quantitatively distinct from, similar tooth morphotypes from other geographic areas. The San Juan Basin contains a diverse record of small theropods. Late Campanian assemblages differ from approximately coeval assemblages of the northern Rockies in being less diverse with only rare representatives of troodontids and a Dromaeosaurus-like taxon. We also provide evidence that erect and recurved morphs of a Richardoestesia-like taxon represent a single heterodont species. A late Maastrichtian assemblage is dominated by a distinct troodontid. The differences between northern and southern faunas based on isolated theropod teeth provide evidence for provinciality in the late Campanian and the late Maastrichtian of North America. However, there is no indication that major components of small-bodied theropod diversity were lost

    During ornithological studies in the provinces of Jujuy, Salta, and San Juan, we recorded the Andean Swallow Orochelidon andecola at 40 localities. These are the first records in Argentina, and also represent the southernmost for the species. Some of these localities are up to 1500 m lower than the previously known elevational limit (now 800 masl), and up to 1100 km southwards. This is a relatively poorly known swallow, and we present novel natural history data. We found evidence of breeding ...

    2013-01-01

    In 2002, the U.S. Geological Survey (USGS) estimated undiscovered oil and gas resources that have the potential for additions to reserves in the San Juan Basin Province, New Mexico and Colorado. Paleozoic rocks were not appraised. The last oil and gas assessment for the province was in 1995. There are several important differences between the 1995 and 2002 assessments. The area assessed is smaller than that in the 1995 assessment. This assessment of undiscovered hydrocarbon resources in the San Juan Basin Province also used a slightly different approach in the assessment, and hence a number of the plays defined in the 1995 assessment are addressed differently in this report. After 1995, the USGS has applied a total petroleum system (TPS) concept to oil and gas basin assessments. The TPS approach incorporates knowledge of the source rocks, reservoir rocks, migration pathways, and time of generation and expulsion of hydrocarbons; thus the assessments are geologically based. Each TPS is subdivided into one or more assessment units, usually defined by a unique set of reservoir rocks, but which have in common the same source rock. Four TPSs and 14 assessment units were geologically evaluated, and for 13 units, the undiscovered oil and gas resources were quantitatively assessed.

    In Puerto Rico, relative to the United States, a disparity exists in detecting oral precancers and early cancers. To identify factors leading to the deficit in early detection, we obtained the perspectives of San Juan healthcare practitioners whose practice could be involved in the detection of such oral lesions. Key informant (KI) interviews were conducted with ten clinicians practicing in or around San Juan, Puerto Rico. We then triangulated our KI interview findings with other data sources, including recent literature on oral cancer detection from various geographic areas, current curricula at the University of Puerto Rico Schools of Medicine and Dental Medicine, as well as local health insurance regulations. Key informant-identified factors that likely contribute to the detection deficit include: many practitioners are deficient in knowledge regarding oral cancer and precancer; oral cancer screening examinations are limited regarding which patients receive them and the elements included. In Puerto Rico, specialists generally perform oral biopsies, and patient referral can be delayed by various factors, including government-subsidized health insurance, often referred to as Reforma. Reforma-based issues include often inadequate clinician knowledge regarding Reforma requirements/provisions, diagnostic delays related to Reforma bureaucracy, and among primary physicians, a perceived financial disincentive in referring Reforma patients. Addressing these issues may be useful in reducing the deficit in detecting oral precancers and early oral cancer in Puerto Rico.

    Fassett, J.E.

    2009-01-01

    In this issue of Palaeontologia Electronica Lucas, et al. (2009) question the validity f the Fassett (2009) paper that presented evidence for Paleocene dinosaurs in the San Juan Basin of New Mexico and Colorado. Their challenges focus primarily on the lithostratigraphy, palynology, and paleomagnetism of the dinosaur-bearing Ojo Alamo Sandstone, shown by Fassett to be of Paleocene age. The lithostratigraphy of the Ojo Alamo is addressed by Lucas et al. (2009) based on detailed studies of outcrops of this formation in two relatively small areas in the southern San Juan Basin where Ojo Alamo dinosaur fossils have been found. When viewed over its 13,000 km2 extent, the Ojo Alamo is seen to be a much more complex formation than these authors recognize, thus their perception and description of the lithostratigraphy of this rock unit is limited and provincial. Fassett (2009) presented a detailed discussion of the palynology of the rocks adjacent to the Cretaceous-Tertiary (K-T) interface in the San Juan Basin, including a 67-page appendix and 25 tables listing the 244 palynomorph species identified from these strata. The Ojo Alamo Sandstone produced 103 palynomorphs from five principal localities including one especially prolific sample set from drill core through K-T strata. Without exception, all samples collected from the Ojo Alamo Sandstone for palynologic analysis were found to contain Paleocene palynomorph assemblages. Lucas et al. challenge only one Ojo Alamo palynomorph assemblage from one of the five areas studied, stating that they were unable to find palynomorph-productive samples at that locality. They submit no new palynologic data that refutes the Paleocene palynologic age of the Ojo Alamo Sandstone. In addressing the paleomagnetism of the Ojo Alamo, these authors dismiss the presence of a critical normal-polarity magnetochron discovered in the lower part of the Ojo Alamo - magnetochron C29n.2n of Fassett (2009) with no evidence to justify this dismissal

    Within the Southwest Regional Partnership on Carbon Sequestration (SWP), three demonstrations of geologic CO{sub 2} sequestration are being performed -- one in an oilfield (the SACROC Unit in the Permian basin of west Texas), one in a deep, unmineable coalbed (the Pump Canyon site in the San Juan basin of northern New Mexico), and one in a deep, saline reservoir (underlying the Aneth oilfield in the Paradox basin of southeast Utah). The Pump Canyon CO{sub 2}-enhanced coalbed methane (CO{sub 2}/ECBM) sequestration demonstration project plans to demonstrate the effectiveness of CO{sub 2} sequestration in deep, unmineable coal seams via a small-scale geologic sequestration project. The site is located in San Juan County, northern New Mexico, just within the limits of the high-permeability fairway of prolific coalbed methane production. The study area for the SWP project consists of 31 coalbed methane production wells located in a nine section area. CO{sub 2} was injected continuously for a year and different monitoring, verification and accounting (MVA) techniques were implemented to track the CO{sub 2} movement inside and outside the reservoir. Some of the MVA methods include continuous measurement of injection volumes, pressures and temperatures within the injection well, coalbed methane production rates, pressures and gas compositions collected at the offset production wells, and tracers in the injected CO{sub 2}. In addition, time-lapse vertical seismic profiling (VSP), surface tiltmeter arrays, a series of shallow monitoring wells with a regular fluid sampling program, surface measurements of soil composition, CO{sub 2} fluxes, and tracers were used to help in tracking the injected CO{sub 2}. Finally, a detailed reservoir model was constructed to help reproduce and understand the behavior of the reservoir under production and injection operation. This report summarizes the different phases of the project, from permitting through site closure, and gives the

    The authors conducted a detailed geologic appraisal, estimated gas in place and recoverable volumes, and evaluated the impact of technology improvements on potential Cretaceous (Pictured Cliffs, Chacra, Cliff House, Point Lookout and Dakota intervals) tight gas reserves of the San Juan Basin. This report summarizes the results of a disaggregated appraisal of the undeveloped San Juan tight gas resource in the context of current and near-term technology, project economics and market potential. A geologic data base was constructed based on location reservoir properties, and typical well recoveries were modeled on a township-specific basis. Project costing and cash flow economics were analyzed to derive potential reserves for various technology specifications and wellhead prices. These data provide a foundation for operators and pipelines to more closely examine these tight formations for development in the near future. Gas in place for the undeveloped tight portion of the five intervals studied was estimated at 17.2 Tcf, with the Dakota Formation accounting for two thirds of this volume. Using current technology, potential ultimate recovery for all intervals is 7.2 Tcf. Potential reserve additions are 1.1 Tcf at $1.50/Mcf, 2.3 Tcf at $2.00/Mcf, and 5.9 Tcf at $5.00/Mcf. The availability of the Nonconventional Fuels Tax Credit for eligible wells drilled in 1991 and 1992 could improve project economics by an after tax equivalent of $0.66/Mcf at the wellhead. Over 300 geophysical logs were evaluated to construct depth, overburden and isopach maps and a location-specific resource database. The database was analyzed using TGAS-PC{reg_sign}, an integrated engineering and economics model for tight sands that has the capability to do rapid sensitivity analysis of geological, technology and economic assumptions.

    Chytridiomycosis is a major threat to amphibian conservation. In Argentina, the pathogenic fungus Batrachochytrium dendrobatidis has been recorded in several localities, and recently, it was registered in amphibians inhabiting low-elevation areas of mountain environments in Córdoba and San Luis provinces. In the present study, we searched for B. dendrobatidis in endemic and non-endemic amphibians on the mountain tops of Córdoba and San Luis provinces. We collected dead amphibians in the upper vegetation belt of the mountains of Córdoba and San Luis. Using standard histological techniques, the presence of fungal infection was confirmed in 5 species. Three of these species are endemic to the mountain tops of both provinces. Although there are no reported population declines in amphibians in these mountains, the presence of B. dendrobatidis in endemic species highlights the need for long-term monitoring plans in the area.

Executive summary--2002 assessment of undiscovered oil and gas resources in the San Juan Basin Province, exclusive of Paleozoic rocks, New Mexico and Colorado: Chapter 1 in Total petroleum systems and geologic assessment of undiscovered oil and gas resources in the San Juan Basin Province, exclusive of Paleozoic rocks, New Mexico and Colorado

    In 2002, the U.S. Geological Survey (USGS) estimated undiscovered oil and gas resources that have the potential for additions to reserves in the San Juan Basin Province (5022), New Mexico and Colorado (fig. 1). Paleozoic rocks were not appraised. The last oil and gas assessment for the province was in 1995 (Gautier and others, 1996). There are several important differences between the 1995 and 2002 assessments. The area assessed is smaller than that in the 1995 assessment. This assessment of undiscovered hydrocarbon resources in the San Juan Basin Province also used a slightly different approach in the assessment, and hence a number of the plays defined in the 1995 assessment are addressed differently in this report. After 1995, the USGS has applied a total petroleum system (TPS) concept to oil and gas basin assessments. The TPS approach incorporates knowledge of the source rocks, reservoir rocks, migration pathways, and time of generation and expulsion of hydrocarbons; thus the assessments are geologically based. Each TPS is subdivided into one or more assessment units, usually defined by a unique set of reservoir rocks, but which have in common the same source rock. Four TPSs and 14 assessment units were geologically evaluated, and for 13 units, the undiscovered oil and gas resources were quantitatively assessed.

Se determinó el número de generaciones anuales y se estudiaron las fluctuaciones poblacionales asociadas a la integral térmica para la especie en esta región. D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario.

    Full Text Available San Carlos de Bariloche es la principal localidad turística de la Patagonia argentina. Representa, por su dimensión, a la ciudad más poblada de la provincia de Río Negro y es la tercera en tamaño en la Patagonia. Su crecimiento demográfico ha estado nutrido por diferentes migraciones nacionales y extranjeras. De estas últimas las principales provienen de países latinoamericanos. El artículo apunta a indagar en  la desvalorización de su migración más importante, la chilena, durante la segunda mitad del siglo XX. Esta exclusión se fortaleció entre 1966 y 1983, por las iniciativas estatales que exacerbaron la xenofobia, las persecuciones políticas, la precarización de las condiciones laborales y los cambios en la organización espacial durante los gobiernos dictatoriales del período, esto es, los que se desarrollaron de 1966 a 1973 y de 1976 a 1983. El presente artículo analiza cómo algunos espacios de Bariloche se constituyeron en marcas urbanas que representaron intereses de los sectores más visibles en nombre de la “nación”, al tiempo que revisa dispositivos de resistencia de sectores excluidos de migrantes chilenos, que tuvieron, paralelamente, componentes de construcción espacial. Para este último punto se aborda la construcción de la Capilla Nuestra Señora del Carmen en 1966, construida en el área conocida como “barrio de los chilenos”, que se levantó como una marca alternativa, tanto material como simbólica, para disputar pertenencia, reconocimiento y visibilidad.

    The U.S Geological Survey (USGS) periodically conducts assessments of undiscovered oil and gas resources in the United States. The purpose of the U.S. Geological Survey National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The last major USGS assessment of oil and gas of the most important oil and gas provinces in the United States was in 1995 (Gautier and others, 1996). Since then a number of individual assessment provinces have been reappraised using new methodology. This was done particularly for those provinces where new information has become available, where new methodology was expected to reveal more insight to provide a better estimate, where additional geologic investigation was needed, or where continuous accumulations were deemed important. The San Juan Basin was reevaluated because of industry exploitation of new hydrocarbon accumulations that were not previously assessed and because of a change in application of assessment methodology to potential undiscovered hydrocarbon accumulations. Several changes have been made in this study. The methodology is different from that used in 1995 (Schmoker, 2003; Schmoker and Klett, 2003). In this study the total petroleum system (TPS) approach (Magoon and Dow, 1994) is used rather than the play approach. The Chama Basin is not included. The team of scientists studying the basin is different. The 1995 study focused on conventional accumulations, whereas in this 2002 assessment, it was a priority to assess continuous-type accumulations, including coal-bed gas. Consequently we are presenting here an entirely new study and results for the San Juan Basin Province. The results of this 2002 assessment of undiscovered oil and gas resources in the San Juan Basin Province (5022) are presented in this report within the geologic context of individual TPSs and their assessment units (AU) (table 1).

    The alpine critical zone is affected by various inputs, storages, pathways, and outputs. Unfortunately, many of these processes distribute the pollutants beyond the immediate area and into the surrounding biological and anthropogenic communities. Years of mining and improper disposal of the tailings and acid-mine drainage have degraded the quality of surface water within the San Juan Mountains. However, mining may not be the only factor significantly affecting the surface water quality in this high-elevation environment. As a high elevation system, this area is a fragile ecosystem with inputs ranging from local mining to atmospheric transport and deposition. Studies from around the world have shown atmospheric transport and deposition affect high-elevation systems. Thus, a significant question arises: does elevation or aspect affect the volume and rate of atmospheric deposition of pollutants? We assume atmospheric deposition occurs on the slopes in addition to in streams, lakes, and ponds. Deposition on slopes can be transported to nearby surface waters and increase the impact of the atmospheric pollutants along with residence time. Atmospheric deposition data were collected for aluminum, iron, manganese, nitrate, phosphate, and sulfate. Water chemistry data were collected for the same constituents as the atmospheric deposition with the addition of temperature, dissolved oxygen, pH, and specific conductance. Deposition samples were collected on a five-day sampling regime during two summers. Water quality samples were collected in-stream adjacent to the deposition-ample collectors. Collection sites were located on opposite sides of Red Mountain at five equal elevations providing two different aspects. The north side is drained by Red Mountain Creek and the south side is drained by Mineral Creek. Differences in atmospheric deposition and water quality at different elevations and aspects suggest there is a relationship between aspect and elevation on atmospheric

    The Lewis Shale Total Petroleum System (TPS) in the San Juan Basin Province contains a continuous gas accumulation in three distinct stratigraphic units deposited in genetically related depositional environments: offshore-marine shales, mudstones, siltstones, and sandstones of the Lewis Shale, and marginal-marine shoreface sandstones and siltstones of both the La Ventana Tongue and the Chacra Tongue of the Cliff House Sandstone. The Lewis Shale was not a completion target in the San Juan Basin (SJB) in early drilling from about the 1950s through 1990. During that time, only 16 wells were completed in the Lewis from natural fracture systems encountered while drilling for deeper reservoir objectives. In 1991, existing wells that penetrated the Lewis Shale were re-entered by petroleum industry operators in order to fracture-stimulate the Lewis and to add Lewis gas production onto preexisting, and presumably often declining, Mesaverde Group production stratigraphically lower in the section. By 1997, approximately 101 Lewis completions had been made, both as re-entries into existing wells and as add-ons to Mesaverde production in new wells. Based on recent industry drilling and completion practices leading to successful gas production from the Lewis and because new geologic models indicate that the Lewis Shale contains both source rocks and reservoir rocks, the Lewis Shale TPS was defined and evaluated as part of this U.S. Geological Survey oil and gas assessment of the San Juan Basin. Gas in the Lewis Shale Total Petroleum System is produced from shoreface sandstones and siltstones in the La Ventana and Chacra Tongues and from distal facies of these prograding clastic units that extend into marine rocks of the Lewis Shale in the central part of the San Juan Basin. Reservoirs are in shoreface sandstone parasequences of the La Ventana and Chacra and their correlative distal parasequences in the Lewis Shale where both natural and artificially enhanced fractures produce

    The efficacy of airborne spectroscopic, or "hyperspectral," remote sensing for geoenvironmental watershed evaluations and deposit-scale mapping of exposed mineral deposits has been demonstrated. However, the acquisition, processing, and analysis of such airborne data at regional and national scales can be time and cost prohibitive. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor carried by the NASA Earth Observing System Terra satellite was designed for mineral mapping and the acquired data can be efficiently used to generate uniform mineral maps over very large areas. Multispectral remote sensing data acquired by the ASTER sensor were analyzed to identify and map minerals, mineral groups, hydrothermal alteration types, and vegetation groups in the western San Juan Mountains, Colorado, including the Silverton and Lake City calderas. This mapping was performed in support of multidisciplinary studies involving the predictive modeling of surface water geochemistry at watershed and regional scales. Detailed maps of minerals, vegetation groups, and water were produced from an ASTER scene using spectroscopic, expert system-based analysis techniques which have been previously described. New methodologies are presented for the modeling of hydrothermal alteration type based on the Boolean combination of the detailed mineral maps, and for the entirely automated mapping of alteration types, mineral groups, and green vegetation. Results of these methodologies are compared with the more detailed maps and with previously published mineral mapping results derived from analysis of high-resolution spectroscopic data acquired by the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) sensor. Such comparisons are also presented for other mineralized and (or) altered areas including the Goldfield and Cuprite mining districts, Nevada and the central Marysvale volcanic field, Wah Wah Mountains, and San Francisco Mountains, Utah.

    Two morphologically distinct forms of an intraerythrocytic parasite(s) were detected by microscopic observation of Giemsa-stained blood films in 45.7% of 119 rockfish (Sebastes emphaeus) from the San Juan Archipelago (Washington State, U.S.A.). Infection prevalence for both forms was 53% in males, 44% in females, and 33% in fish of undetermined gender. A binucleate "ring-stage" was present at all 4 geographic sites, with a mean prevalence of 45.7%, while mean prevalence of a larger gamont-like form from the same sites was 5.1%. The relationship of the 2 forms to each other could not be determined. Neither schizogony nor binary fission was evident in any of the infected erythrocytes and the parasites contained no obvious pigment. The possibility of the 2 morphologic forms being 2 distinct species is supported by the observation that no difference in parasitemia was seen in the binucleate form among sites (1.6-1.9%), while parasitemia of the gamont-like form varied significantly among sites, ranging from a high of 4% to a low of 0.1%. Taxonomic status of either form could not be determined at this time based on limited existing morphologic data. ?? American Society of Parasitologists 2005.

    Full Text Available For decades, the documentation of rock art has been the backbone of the research on this cultural practice. However, traditional techniques used for this purpose have proved to be imprecise and subjective. With the advent of the digital age there has been a revolution in the field of rock art documentation in general and in particular for petroglyphs. Techniques such as digital nightlight photography or three-dimensional (3D photogrammetry have opened a world of possibilities. In the case of nightlight photography, its use goes back to the second half of the 20th century. However, in recent years the emergence of high-power digital cameras along with new lighting systems unthinkable decades ago, such as tactical flashlights, have rejuvenated a technique that seems incombustible. After the numerous tests carried out by the DIPAR (Integral Rock Art Documentation System project team, it has become evident that, correctly employed, this technique still has immense potential in the field of rock art documentation, especially if we take into consideration its low cost and ease of use. Photogrammetry, on the other hand, is shown as the perfect complement to the records obtained through digital nightlight photography. The possibility of applying filters or shaders that increase the visibility of the digitized petroglyphs, within a metric scheme, is a great advance in their documentation. This paper explores the advantages associated with these techniques with a case study: unpublished petroglyphs of Alcázar de San Juan (Spain.

    A survey of 10 producers of conventional corn (Hybrids PAC 105 and Maximus) and 10 producers of transgenic corn (Pioneer Hybrid 30T17) was carried out in the municipality of Valle de San Juan in the territorial division of Tolima (Colombia), in order to analyze the differences in production costs and environmental impacts of these two agricultural technologies.  The environmental impacts were determined by calculating the field "Environmental Index Quotient" (EIQ). In the production cost analysis, a difference of 15% was found in benefit of the transgenic technology. The structure of costs of the transgenic technology was benefited by the reduced use of pesticides (insecticides and herbicides). In regards to production, the transgenic technology showed a greater yield, 5.22 ton/ha in comparison to 4.25 ton/ha the conventional technology, thus a 22% difference in yield. Finally, the EIQ calculation showed quantitative differences of 196.12 for the conventional technology (EIQ insecticides 165.14 + EIQ herbicides 30.98), while the transgenic technology was of 4.24 (EIQ insecticides 0 + EIQ herbicides 4.24). These results show a minor environmental impact when using the transgenic technology in comparison to the conventional technology, in regards to the use of insecticides and herbicides in a temporal, spatial and genotypical context analysis. :

    Full Text Available Natural Protected Areas (NPAs includes important species richness, and it is assumed that these are the best areas for biodiversity conservation. There are certain doubts, however, about the effectiveness of the NPAs in developing countries, where economic resources for conservation are scarce and NPAs are not monitored and managed efficiently. In the present study we assessed the species richness, diversity, abundance, and functional guilds of amphibians and reptiles inside and outside of the NPA Reserva Estatal de la Biósfera Sierra San Juan (REBSSJ, Nayarit, Mexico. Our results showed that species numbers of amphibian and reptiles were higher outside than inside the reserve, as well the individual number distributed among species, except for lizard species. Analyses of functional guilds showed that both richness and functional dispersion were greater in amphibians and reptiles outside the reserve. Likewise, outside the reserve we recorded a higher species number with some category of risk at the national level (NOM-059, international level (IUCN, and also by using the Environmental Vulnerability Score (EVS algorithm. The results suggest that areas outside of the reserve are crucial to the maintenance of regional biodiversity, due to high complementarity with species composition inside of the reserves. These data can be used to implement conservation measures that include a new demarcation of the reserve and the consideration of surrounding areas to include a great number of species.

    The assessment of caprocks for geologic CO{sub 2} storage is a multi-scale endeavor. Investigation of a regional caprock - the Kirtland Formation, San Juan Basin, USA - at the pore-network scale indicates high capillary sealing capacity and low permeabilities. Core and wellscale data, however, indicate a potential seal bypass system as evidenced by multiple mineralized fractures and methane gas saturations within the caprock. Our interpretation of {sup 4}He concentrations, measured at the top and bottom of the caprock, suggests low fluid fluxes through the caprock: (1) Of the total {sup 4}He produced in situ (i.e., at the locations of sampling) by uranium and thorium decay since deposition of the Kirtland Formation, a large portion still resides in the pore fluids. (2) Simple advection-only and advection-diffusion models, using the measured {sup 4}He concentrations, indicate low permeability ({approx}10-20 m{sup 2} or lower) for the thickness of the Kirtland Formation. These findings, however, do not guarantee the lack of a large-scale bypass system. The measured data, located near the boundary conditions of the models (i.e., the overlying and underlying aquifers), limit our testing of conceptual models and the sensitivity of model parameterization. Thus, we suggest approaches for future studies to better assess the presence or lack of a seal bypass system at this particular site and for other sites in general.

    Full Text Available Enterococci concentration variability at Escambron Beach, San Juan, Puerto Rico, was examined in the context of environmental conditions observed during 2005–2015. Satellite-derived sea surface temperature (SST, turbidity, direct normal irradiance, and dew point were combined with local precipitation, winds, and mean sea level (MSL observations in a stepwise multiple regression analyses (Akaike Information Criteria model selection. Precipitation, MSL, irradiance, SST, and turbidity explained 20% of the variation in observed enterococci concentrations based upon these analyses. Changes in these parameters preceded increases in enterococci concentrations by 24 h up to 11 days, particularly during positive anomalies of turbidity, SST, and 480–960 mm of accumulated (4 days precipitation, which relates to bacterial ecology. Weaker, yet still significant, increases in enterococci concentrations were also observed during positive dew point anomalies. Enterococci concentrations decreased with elevated irradiance and MSL anomalies. Unsafe enterococci concentrations per US EPA recreational water quality guidelines occurred when 4-day cumulative precipitation ranged 481–960 mm; irradiance < 667 W·m−2; daily average turbidity anomaly >0.005 sr−1; SST anomaly >0.8 °C; and 3-day average MSL anomaly <−18.8 cm. This case study shows that satellite-derived environmental data can be used to inform future water quality studies and protect human health.

    2013-01-01

    Multispectral satellite data acquired by the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and Landsat 7 Enhanced Thematic Mapper Plus (TM) sensors are being used to populate an online Geographic Information System (GIS) of the spatial occurrence of mineral groups and green vegetation across the western conterminous United States and Alaska. These geospatial data are supporting U.S. Geological Survey national-scale mineral deposit database development and other mineral resource and geoenvironmental research as a means of characterizing mineral exposures related to mined and unmined hydrothermally altered rocks and mine waste. This report introduces a new methodology for the automated analysis of Landsat TM data that has been applied to more than 180 scenes covering the western United States. A map of mineral groups and green vegetation produced using this new methodology that covers the western San Juan Mountains, Colorado, and the Four Corners Region is presented. The map is provided as a layered GeoPDF and in GIS-ready digital format. TM data analysis results from other well-studied and mineralogically characterized areas with strong hydrothermal alteration and (or) supergene weathering of near-surface sulfide minerals are also shown and compared with results derived from ASTER data analysis.

    Radon levels in two old mines in San Luis, Argentina, were measured and analyzed. La Carolina gold mine and Los Condores tungsten mine are today used as tourism mines. CR-39 nuclear track detectors were used for this purpose. Measurements were performed during both winter and summer seasons. The findings show that in these environments, significant radon concentrations are subject to large seasonal fluctuations, due to the strong dependence on natural ventilation with the outside temperature variations. For both mines, high concentration values of {sup 222}Rn were observed in summer and low values in winter; with an extreme ratio of 2.5 times between summer and winter seasons for Los Condores mine. The radiation dose and environmental health risk of {sup 222}Rn concentrations to both guides and visitors were estimated for both seasons and compared with dose and action level values recommended by the International Commission on Radiological Protection (ICRP). The radon contribution to the effective dose rate for visitors has been previously assessed for the warm season. The values are 0.38±0.07 mSv y{sup -1} and 0.05±0.02 mSv y{sup -1} for La Carolina and Los Condores, respectively. These values were obtained assuming an accumulated annual time underground of 20 h. For the guides these values are 11±2 mSv y{sup -1} and 1.45±0.5 mSv y{sup -1} for La Carolina and Los Condores, respectively, assuming an accumulated annual time underground of 600 h. The occupational dose rate limit suggested by the ICRP is 20 mSv y{sup -1}. As these values indicate the dose is an order of magnitude lower in Los Condores than La Carolina mine. This is because this mine, due to its characteristics, is more ventilated than La Carolina mine. This is important because actions can be taken to lower the radon accumulation in La Carolina gold mine, for example by opening new ducts to increase air circulation. Finally, in this work, seasonal variations of the dose rate are assessed and

    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.

    Urbanization, along with other cases of land cover and land use changes, has significant climate impacts in tropical regions with the added complexity of occurring within the context of global warming. The individual and combined effects of these two factors on the surface energy balance of a tropical city are investigated by use of an integrated atmospheric modeling approach, taking the San Juan Metropolitan Area (SJMA), Puerto Rico as the test case. To achieve this goal, an ensemble of climate and weather simulations is performed, with the climate scenarios combining urban development and sprawl with regional climate change over the past 50 years, and the short-term simulations designed to test the sensitivity to different urban vegetation configurations as mitigating alternatives. As indicator of change, we use the thermal response number (TRN), which is a measure of the sensible heating to the thermal storage of a surface or region, and the Bowen ratio, which is defined as the ratio of sensible to latent heat fluxes. The TRN of the area occupied by the SJMA has decreased as a consequence of replacing the low land coastal plain vegetation with man made materials, indicating that it takes less energy to raise the surface temperature of the urban area, whereas the TRN of forested regions has remained virtually unchanged. The global warming signal also has effects on the thermal response of the SJMA, where dryer current conditions generate lower TRN values. Differences due to global warming are more evident in the Bowen ratio pattern, mostly associated with the drier present conditions observed and its effects on sensible and latent heat fluxes. In terms of testing different mitigation strategies, the short-term simulations show that the urban area is more efficient in partitioning surface energy balance terms when green roofs are specified, as opposed to including vegetation inside the urban core.

    2013-08-01

    Full Text Available This article reflects on the concept of “national landscape” and on the importance of identity symbolic values in the beginning of landscape and nature conservation policy in Spain. The emblematic case of the Montaña de Covadonga (the first National Park created in Spain is examined in more detail. The paper is divided into three main sections. The first one raises some theoretical and general considerations on the role of identity symbolic values within the first steps of nature conservation policies in Spain and other national contexts. Secondly, the cultural-historic processes and discourses which converted the Montaña de Covadonga landscape into a Spanish national symbol and into a site of memory, leading to its declaration as a National Park in 1918, are reviewed. The third section examines the ideological identity disputes and controversies concerning the creation of that National Park, some of which led to the declaration of the Sitio Nacional del Monte de San Juan de la Peña in 1920. The article approaches the creation of the first Spanish Natural Parks as a part of the nationalization policies inspired by the concerns of the “Regeneracionismo”. More precisely, the beginning of natural conservation policy in Spain may be considered as part of the efforts carried out by certain intellectual and political leaders in order to institutionalize new spaces of collective identity grounded in landscape and nature (and, more particularly, in some natural landscapes endowed with a strong historic symbolic meaning as regards to the “birth of the nation”. According to the research conclusions, the ideological controversies raised around the first Spanish Natural Parks can be understood as a reflection of the plurality of competing national conceptions existing in Spain, as well as of the difficulties in reaching a consensus on the country’s national symbols.

Dentro de un enfoque ecosistémico, se establecieron las relaciones de entradas y salidas de materia
    y energía, al igual que las relaciones internas del sistema agrícola; de esta manera se determinó si el sistema utilizado era sostenible. Por medio de preguntas en torno al funcionamiento y manejo del sistema agrícola, se pudo establecer que la finca cumple con los supuestos de sustentabilidad, debido a que la energía invertida en el manejo del sistema es equivalente o menor a la producción obtenida. De esta manera la producción se mantiene durante el año y es suficiente para asegurar la alimentación básica de la familia. El plan de manejo de la finca ha restablecido procesos ecológicos que logran regular los componentes del sistema. Este modelo ha propiciado el control biológico natural por medio de un manejo integrado de plagas; el mantenimiento de alta biodiversidad (más de 200 variedades de plantas; y el ciclaje interno de nutrientes suficiente para proveer energéticamente al sistema, evitando los subsidios de energía externa. Finalmente, se puede promover una integración regional, si más unidades productivas acogen este sistema, que aunque
    debe mejorar en sus procesos, conseguiría que la población campesina se agrupe y obtenga mayores beneficios de estas prácticas, entre ellos la ampliación de los mercados.

    Full Text Available Este artículo ofrece los resultados de un estudio comparado de dos municipios: Venado Tuerto y San Rafael de la República Argentina, que presentaron tendencias diferentes en relación a las tasas de homicidios por armas de fuego. La metodología combinó dos estrategias de análisis: por un lado, entrevistas semi-estructuradas con informantes clave (funcionarios municipales y provinciales en distintas áreas de la gestión, y referentes de organizaciones no gubernamentales y, por el otro, grupos focales con actores vinculados a la atención médica, la educación y las instituciones religiosas. Los resultados sugieren una distancia muy corta entre las ciudades en las cuales las tasas han aumentado y aquellas en las que han disminuido. La diferencia más significativa es que en Venado Tuerto se encontró una mayor fragilidad en las instituciones públicas, por la falta de articulación entre las mismas. En tanto en San Rafael, los actores entrevistados atribuyen el bajo nivel de conflictividad a una red de prevención de violencias en la cual se coordinan agencias provinciales y municipales. Sin tratarse, ni Venado Tuerto, ni San Rafael, de ciudades violentas en los niveles latinoamericanos más truculentos, ambas muestran resultados diferentes que apuntan directamente a la posibilidad de juntar a las instituciones en un entramado de conversaciones, acuerdos y políticas en conjunto.This article presents the results of a comparative study of two Argentinian cities, namely Venado Tuerto and San Rafael, which revealed different trends in the rates of firearm-related homicides.

  11. New geochronologic and stratigraphic evidence confirms the paleocene age of the dinosaur-bearing ojo alamo sandstone and animas formation in the San Juan Basin, New Mexico and Colorado

    2009-01-01

    Dinosaur fossils are present in the Paleocene Ojo Alamo Sandstone and Animas Formation in the San Juan Basin, New Mexico, and Colorado. Evidence for the Paleo-cene age of the Ojo Alamo Sandstone includes palynologic and paleomagnetic data. Palynologic data indicate that the entire Ojo Alamo Sandstone, including the lower dinosaur-bearing part, is Paleocene in age. All of the palynomorph-productive rock samples collected from the Ojo Alamo Sandstone at multiple localities lacked Creta-ceous index palynomorphs (except for rare, reworked specimens) and produced Paleocene index palynomorphs. Paleocene palynomorphs have been identified strati-graphically below dinosaur fossils at two separate localities in the Ojo Alamo Sand-stone in the central and southern parts of the basin. The Animas Formation in the Colorado part of the basin also contains dinosaur fossils, and its Paleocene age has been established based on fossil leaves and palynology. Magnetostratigraphy provides independent evidence for the Paleocene age of the Ojo Alamo Sandstone and its dinosaur-bearing beds. Normal-polarity magnetochron C29n (early Paleocene) has been identified in the Ojo Alamo Sandstone at six localities in the southern part of the San Juan Basin. An assemblage of 34 skeletal elements from a single hadrosaur, found in the Ojo Alamo Sandstone in the southern San Juan Basin, provided conclusive evidence that this assemblage could not have been reworked from underlying Cretaceous strata. In addition, geochemical studies of 15 vertebrate bones from the Paleocene Ojo Alamo Sandstone and 15 bone samples from the underlying Kirtland Formation of Late Creta-ceous (Campanian) age show that each sample suite contained distinctly different abundances of uranium and rare-earth elements, indicating that the bones were miner-alized in place soon after burial, and that none of the Paleocene dinosaur bones ana-lyzed had been reworked. ??

La reapertura democrática argentina en 1983, y al casi simultáneo proyecto de integración económica del Cono Sur americano, denominado Mercosur, está implicando que economías nacionales relativamente cerradas se vayan abriendo e integrando en un solo mercado con la finalidad de conseguir mayor competitividad y asegurar mercados. Esto exige que las fronteras internacionales se tornen más permeables. La heterogeneidad de actores (sacerdotes, políticos, devotos, etc. e intereses (económicos, turísticos, religiosos, etc. de la fiesta indican su multivocalidad; y como el propio origen de la celebración está ligado al corte de las relaciones intercordilleranas hacia mitad del siglo XX, la devoción a San Sebastián aparece como un mediador entre la localidad y la nación argentina, su pasado chileno y la institucionalidad de la Iglesia Católica. Finalmente, el análisis de la organización y el significado de la celebración nos permite entonces reflexionar sobre ciertas categorías clásicas y en apariencia antagónicas de la antropología como tradición/innovación o conflicto/armonía.In this article we trace the changes undergone by the cult and festival of San Sebastian in Las Ovejas, Neuquén, near the Chilean border, over recent years.

    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.

  6. A geospatial data integration framework for mapping and monitoring tropical landscape diversity in Costa Rica's San Juan-La Selva Biological Corridor

    Science.gov (United States)

    Sesnie, Steven E.

    Landcover change has substantially reduced the amount of tropical rain forest since the 1950s. Little is known about the extent of remaining forest types. A multivariate analysis of 144 forest plots across Costa Rica's San Juan - La Selva Biological Corridor resulted in eight floristically defined old-growth forest categories. Spectral separability was tested between categories using Landsat TM bands and vegetation indices for old-growth types, palm swamps, tree plantations and regrowth. Image filtering and NDVI increased spectral separability among categories by 30%. Separability tests resulted in seven well-discriminated forest categories. Factors driving forest beta-diversity are not well quantified for wet tropical environments. We examined the relationship between rain forest composition and environmental variation for a 3000 km2 area in northeastern Costa Rica. Mid- to upper-canopy tree species abundance and soil characteristics were measured from 127, 0.25-ha plots across Caribbean lowlands and foothills. Partial Mantel tests produced significant correlations between floristic distance and soil, terrain, and climate variables controlling the effects of geographical distance. Niche-factors showed a significant trend with forest composition more than dispersal limitation or disturbance related factors. Variables such as terrain features, climatic variation and Landsat TM bands associated with forest composition were assessed with two decision tree models. Thirty-two landcover types were compared for a 15-year time interval. Ten were floristic alliances from a cluster analysis of forest plots and wetland categories. A subset of 12 spectral and spatial predictor variables produced accuracies of 93%+/-7% and 83%+/-15% for QUEST and CRUISE classifiers, respectively. The QUEST classifier was accurate for habitat mapping and change detection important to biodiversity monitoring objectives. A 1996 Forestry Law initiated environmental service payments and prohibited

  7. Multi-Scale Transport Properties of Fine-Grained Rocks: A Case Study of the Kirtland Formation, San Juan Basin, USA

    Understanding and characterizing transport properties of fine-grained rocks is critical in development of shale gas plays or assessing retention of CO2 at geologic storage sites. Difficulties arise in that both small scale (i.e., ~ nm) properties of the rock matrix and much larger scale fractures, faults, and sedimentological architecture govern migration of multiphase fluids. We present a multi-scale investigation of sealing and transport properties of the Kirtland Formation, which is a regional aquitard and reservoir seal in the San Juan Basin, USA. Sub-micron dual FIB/SEM imaging and reconstruction of 3D pore networks in core samples reveal a variety of pore types, including slit-shaped pores that are co-located with sedimentary structures and variations in mineralogy. Micron-scale chemical analysis and XRD reveal a mixture of mixed-layer smectite/illite, chlorite, quartz, and feldspar with little organic matter. Analysis of sub-micron digital reconstructions, mercury capillary injection pressure, and gas breakthrough measurements indicate a high quality sealing matrix. Natural full and partially mineralized fractures observed in core and in FMI logs include those formed from early soil-forming processes, differential compaction, and tectonic events. The potential impact of both fracture and matrix properties on large-scale transport is investigated through an analysis of natural helium from core samples, 3D seismic data and poro-elastic modeling. While seismic interpretations suggest considerable fracturing of the Kirtland, large continuous fracture zones and faults extending through the seal to the surface cannot be inferred from the data. Observed Kirtland Formation multi-scale transport properties are included as part of a risk assessment methodology for CO2 storage.

    The Neogene Tiporco Volcanic Complex (TVC) is located in the Sierras Pampeanas of San Luis, Argentina, at the southeast of the Pampean flat-slab segment. Based on the comprehensive study of lithofacies and structures, the reconstruction of the volcanic architecture has been carried out. The TVC has been modeled in three subsequent stages: 1) initial updoming, 2) ignimbritic eruptive activity and 3) lava dome emplacement. Interplay of magma injection and transtensional tectonic deformation has been invoked to reproduce TVC evolution.

D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario.

    Full Text Available The ruins of San Ignacio Miní, in NE Argentina, Misiones Province, included by the UNESCO in the list of World Heritage in 1984, were built in the 18th century by the Guarani people under the supervision of the Jesuite Congregation. The ruins are located in a tropical weather zone, exposed to extreme conditions of heat and humidity affecting the rocks used in its construction. These rocks are identified as siliceous sandstones, mainly formed by rounded to subrounded clasts, with scarce angulose particles, containing 96% quartz. Weather characteristics encourage the growth of vascular plants as well as algae and mosses and other organisms that damage materials. Among these, there are 18 lichen species (belonging to 18 genera, 8 foliose, 3 fruticose and 7 crustose. The damaging action of these lichens has been observed through SEM observations and EDAX microanalysis of rock samples colonized by Caloplaca sp. and Buellia sp.

    Full Text Available The ensemble formed by Saint Martin church and the Falces Palace in Medina del Campo was in a deplorable state, plundered and ruined, when a restoration action was decided. As for San Juan Bautista’s church in Guadalix de la Sierra, only the tower and the apse had an architectural interest, since the nave was a poor reconstruction from 1944. The proposal considered two kinds of interventions. In one hand, the traditional restoration of the few pieces preserved in their original state. In another hand, rebuilding it with a new design that should optimize it for public use and also create an homogeneous coordination of the architectural "fragments" which before had no link between them.

Sandstone reservoirs in the Entrada Sandstone were deposited in eolian depositional environments. Oil in Todilto source beds was generated beginning in the middle Paleocene, about 63 million years ago, and maximum generation of oil occurred in the middle Eocene. In the northern part of the San Juan Basin, possible gas and condensate were generated in Todilto Limestone Member source beds until the middle Miocene. The migration distance of oil from the Todilto source beds into the underlying Entrada Sandstone reservoirs was short, probably within the dimensions of a single dune crest. Traps in the Entrada are mainly stratigraphic and diagenetic. Regional tilt of the strata to the northeast has influenced structural trapping of oil, but also allowed for later introduction of water. Subsequent hydrodynamic forces have influenced the repositioning of the oil in some reservoirs and flushing in others. Seals are mostly the anhydrite and limestone facies of the Todilto, which thin to as little as 10 ft over the crests of the dunes. The TPS contains only one assessment unit, the Entrada Sandstone Conventional Oil Assessment Unit (AU) (50220401). Only four of the eight oil fields producing from the Entrada met the 0.5 million barrels of oil minimum size used for this assessment. The AU was estimated at the mean to have potential additions to reserves of 2.32 million barrels of oil (MMBO), 5.56 billion cubic feet of natural gas (BCFG), and 0.22 million barrels of natural gas liquids (MMBNGL).

    Baseline concentration levels of As, B, Ca, Cd, Cr, Cu, Co, Fe, Mg, Mn, Mo, Ni, P, Pb, Se, V, and Zn were determined for Porphyra columbina and Ulva sp. collected from three locations along San Jorge Gulf, in Patagonia Argentina. Elements were quantified by inductively coupled plasma-optical emission spectrometry, with the exception of lead and cadmium in some samples which were determined by electrothermal atomic absorption spectrometry. Three stations with different exposure degree to human activities, Bahia Solano, the mouth of Arroyo La Mata stream and Punta Maqueda, were selected as sampling points. The results showed a wide range of metal retention capacity between the two studied species. Regarding the levels of pollutants found in the researched sites, Punta Maqueda seemed to be less influenced by anthropogenic activities than the other two sites except for Cd. Taking into account their toxicities seasonal variations in Pb and Cd levels were studied in both algae in Punta Maqueda. Maximum concentrations of Cd (9.8 {mu}g g{sup -1} dry wt.) were observed in P. columbina during winter, and maximum levels of Pb (0.82 {mu}g g{sup -1} dry wt.) were detected in Ulva sp. during summer. Legislative and health safety aspects were evaluated for Cd and Pb.

    Full Text Available ABSTRACT This study estimates and analyses the reproductive parameters and cycle of Sympterygia bonapartii in San Matías Gulf, northern Patagonia, Argentina. A total of 827 males and 1,299 females were analysed. Males ranged from 185 to 687 mm of total length (TL and females from 180 to 742 mm TL. Sexual dimorphism was detected; females were larger, heavier, exhibited heavier livers, wider discs and matured at lager sizes than males. Immature females ranged from 180 to 625 mm TL, maturing females from 408 to 720 mm TL, mature ones from 514 to 742 mm TL and females with egg capsules from 580 to 730 mm TL. Immature males ranged from 185 to 545 mm TL, maturing ones from 410 to 620 mm TL and mature males from 505 to 687 mm TL. Size at which 50% of the skates reached maturity was estimated to be 545 mm TL for males and 594 mm TL for females. According to the reproductive indexes analysed, S. bonapartii exhibited a seasonal reproductive pattern. Mating may occur during winter-early spring and the egg-laying season, during spring and summer.

    Full Text Available The loss of green areas and vegetation in suburban neighborhoods poses short- and long-term consequences associated with environmental changes and socioeconomic decline that can propel such developments to an unsustainable state. We summarize an interdisciplinary investigation aimed at identifying the drivers of green area loss, green cover loss, and quantifying the impact on three inner-ring suburban neighborhoods located along the Rio Piedras watershed in San Juan, Puerto Rico. An inductive approach to social-ecological research was undertaken because it provides a flexible platform for interdisciplinary collaboration on this complex and dynamic subject. The three developments selected for the study were constructed in the mid-20th century under paradigms of modernity that included providing conditions for a better and more dignified way of living, among which green areas played a central role. The green area change analysis was undertaken first, by way of using building footprint growth as a proxy, which represents a minimal estimate of change, and transferring the information from aerial photographs, original development plans, construction drawings, and GIS maps to AutoCAD to quantify building footprint change for each neighborhood. The period of analysis started from the time of the construction of each development to the year 2010. The second estimation was performed using orthorectified infrared aerial imagery to quantify green cover in year 2008 and contrast that information with the conditions at the time the developments were constructed. Green-gray area dynamics were thus analyzed together with longitudinal socioeconomic data to help in the assessment of effects. The investigation revealed long-term socioeconomic declining trends in two of the neighborhoods, weak governance of the built environment, substantial increase in automobile ownership, and distinct physical-spatial characteristics as drivers behind the changes observed.

    The Albuquerque Bernalillo County Water Utility Authority supplements the municipal water supply for the Albuquerque metropolitan area, in central New Mexico, with surface water diverted from the Rio Grande. The U.S. Geological Survey, in cooperation with the Albuquerque Bernalillo County Water Utility Authority, undertook this study in which water-chemistry data and historical streamflow were compiled and new water-chemistry data were collected to characterize the water chemistry and streamflow of the San Juan-Chama Project (SJCP). Characterization of streamflow included analysis of the variability of annual streamflow and comparison of the theoretical amount of water that could have been diverted into the SJCP to the actual amount of water that was diverted for the SJCP. Additionally, a seepage investigation was conducted along the channel between Azotea Tunnel Outlet and the streamflow-gaging station at Willow Creek above Heron Reservoir to estimate the magnitude of the gain or loss in streamflow resulting from groundwater interaction over the approximately 10-mile reach. Generally, surface-water chemistry varied with streamflow throughout the year. Streamflow ranged from high flow to low flow on the basis of the quantity of water diverted from the Rio Blanco, Little Navajo River, and Navajo River for the SJCP. Vertical profiles of the water temperature over the depth of the water column at Heron Reservoir indicated that the reservoir is seasonally stratified. The results from the seepage investigations indicated a small amount of loss of streamflow along the channel. Annual variability in streamflow for the SJCP was an indication of the variation in the climate parameters that interact to contribute to streamflow in the Rio Blanco, Little Navajo River, Navajo River, and Willow Creek watersheds. For most years, streamflow at Azotea Tunnel Outlet started in March and continued for approximately 3 months until the middle of July. The majority of annual streamflow

    Full Text Available The city of San Salvador de Jujuy is analyzed both as a border space and as a city space. Through the systematization of local studies, the aim is to consider the historical, political, socioeconomic, migratory and symbolic elements that create the urban border experience. This contribution focuses on reconstructing the city as a network of senses. It deepens our understanding of migratory flows, the recent political situation, the impact of economic inequality on urbanisms, and the relevance of media and ritual acts in the configuration of dominant senses in cities. In addition, the factors that demarcate the difference and local inequality and the process of peripheralization and impoverishment of the soil are examined. Both the recent political conflicts that affect regional disarticulation and the symbolic disputes that cause tension in national belonging against a strong Andean influence are outlined.

    In response to increasing concern about the quality of irrigation drainage and its potential effects on fish, wildlife, and human health, the U.S. Department of the Interior began the National Irrigation Water Quality Program (NIWQP) to investigate these concerns at irrigation projects sponsored by the Department. The San Juan River in northwestern New Mexico was one of the areas designated for study. Study teams composed of scientists from the U.S. Geological Survey, the U.S. Fish and Wildlife Service, the Bureau of Reclamation, and the Bureau of Indian Affairs collected water, bottom-sediment, soil, and biological samples at 61 sites in the San Juan River area during 1993-94. Supplemental data collection conducted during 1991-95 by the Bureau of Indian Affairs and its contractor extended the time period and sampling sites available for analysis. Analytical chemistry performed on samples indicated that most potentially toxic elements other than selenium generally were not high enough to be of concern to fish, wildlife, and human health. Element concentrations in some water, bottom-sediment, soil, and biological samples exceeded applicable standards and criteria suggested by researchers in current literature. Selenium concentrations in water samples from 28 sites in the study area exceeded the 2-microgram-per-liter wildlife-habitat standard. Vanadium concentrations in water exceeded the 100-microgram-per-liter standard for livestock-drinking water at one site. In biota, selenium and aluminum concentrations regularly equaled or exceeded avian dietary threshold concentrations. In bottom sediment and soil, element concentrations above the upper limit of the baseline range for western soils were: selenium, 24 exceedances; lead, 2 exceedances; molybdenum, 2 exceedances; strontium, 4 exceedances; and zinc, 4 exceedances. Concentrations of total selenium in bottom-sediment and soil samples were significantly greater for Cretaceous than for non-Cretaceous soil types in the

    Full Text Available Las ciudades bajo desarrollo capitalista experimentaron a lo largo de las últimas décadas profundos procesos de fragmentación urbana. Aquellas con función turística agudizaron este panorama dado el aumento del valor del suelo urbano. Tal es el caso de San Carlos de Bariloche, en la Patagonia andina argentina. Su alta compartimentación, sumada a la gran dispersión espacial de su ejido municipal y topografía accidentada, limitaron la funcionalidad y cohesión interna. Se propone avanzar en la comprensión de dichas fracturas urbanas a partir del estudio de las asociaciones vecinales. Se trabaja desde la escala del barrio entendido como condensador de problemáticas globales, nacionales y locales y a partir de la figura de la Junta Vecinal en tanto unidad primaria de participación y principal articuladora en las relaciones entre vecinos, barrios y gobierno local. La hipótesis propone que la gestión, las relaciones y funciones asumidas desde las Juntas Vecinales, íntimamente vinculadas a la condición de clase de sus vecinos, permiten una mejor interacción a escala intraurbana y promueven situaciones más inclusivas en los sectores populares. Se da cuenta también del rol de las Juntas Vecinales en la construcción de imaginarios urbanos que inciden en un acercamiento-alejamiento de las distancias sociales intraurbanas.

    Full Text Available Human relationship with dogs associates with numerous and varied benefits on human health; however, it also presents significant risks. The goal of this study was to describe demographic parameters and characteristics of dog ownership with possible implications on human health and to evaluate the prevalence of dog bites and traffic accidents due to dogs. Interviews were conducted in the neighborhoods of Nuestras Malvinas and Nahuel Hue in San Carlos de Bariloche. The percentage of homes with at least one dog, the average number of dogs per home, the prevalence of dog bites and traffic accidents due to dogs and the general awareness of the population on dog transmitted zoonoses were estimated. Regarding ownership characteristics, the degree of sterilization, vaccination and parasite control and the percentage of dogs allowed to roam freely in public places were evaluated. A total of 141 interviews were conducted; 87% of the households had at least one dog, with an average of 2.2 dogs. In 26% of the households someone had suffered a traffic accident caused by dogs and in 41% someone had been bitten. Antiparasite treatment was administered to 83% of the dogs in the last 12 months, on average 1.4 times (recommended 6 times, 51% were sterilized, 55% were allowed to roam freely. This study shows a disturbing situation regarding the canine population of the evaluated neighborhoods. The number of dogs allowed to roam freely and the low level of parasite control and sterilization provide suitable conditions for the spread of zoonoses.

    Full Text Available This paper deals with the application of satellite images to study turbidity and water circulation patterns in San Blas channel during a theoretical tidal cycle. Eight Landsat TM and ETM images acquired under clear-sky conditions and representing different tidal stages were selected from a pool of Landsat images provided by the argentinean National Commission of Space Activities (CONAE and the US Geological Survey. Standard digital image processing techniques were used to perform geometric and radiometric corrections on the visible and near-infrared bands. An image-based atmospheric correction (COST method by CHAVEZ, 1996 was applied. An ISODATA unsupervised classification was performed in order to identify different turbidity levels throughout the channel and adjacent areas. The results suggest that suspended sediment transport towards the channel mouth by ebb currents occurs along both flanks. These currents carry suspended sediment into the open sea, generating an ebb tidal delta which tends to rotate in a clockwise direction. Flood currents trigger turbidity mostly over the southern flank of the channel, generating a flood tidal delta with elongated banks extending in the direction of the tidal currents. From the elongated shape of the turbidity plumes, general tidal circulation patterns were identified.Este trabalho analisa a turbidez e a circulação da agua no canal San Blas durante um ciclo de maré teórico através de imagens satelitais.

En el texto seleccionado es posible observar la introducción de un discurso de denuncia y desenmascaramiento de las atrocidades cometidas por el poder. En una perspectiva más amplia será factible señalar el modo en que esa revisión crítica de la elite dominante apunta a cuestionar el relato oficial sobre los hechos del pasado, es decir, la forma en que se construye la Historia. A partir de dicho movimiento revisionista, se llega a revelar que la memoria de la historia es producto de una relación de fuerzas que se debe desnudar y denunciar.

    Garnet peridotites are very rare in oceanic subduction complexes, with only two reported occurrences. One is in the Sambagawa metamorphic belt in Shikoku, Japan, and the other example is in the southern part of the Rio Juan Complex, northern Dominican Republic. In both locations, garnet peridotite occurs in close association with eclogites in high metamorphic grade of the terranes. The Rio Juan Complex represents rocks formed during the southwestern subduction of the Proto-Caribbean oceanic plate below the Carribean Plate during late Cretaceous to early Eocene. Garnet peridotites (clinopyroxene[Cpx]-bearing dunite, wehrlite, olivine clinopyroxenite) occur as large (The rocks are all low in Ir-group PGE (Ir, Ru, Os), indicating that they are cumulates of a melt, since these remain in the residue during partial melting. A cumulate origin of the ultramafic rocks is consistent with relatively low Mg contents of olivine (Fo 74-83) compared to olivine in mantle peridotites. Extended trace element plots of the bulk rocks show a so-called "arc geochemical signature" with high fluid-mobile element concentrations, such as Sr, U, and Pb, and low HFSE, such as Nb and Zr, indicating that formation of the parental magmas were related to subduction. Two representative garnet-bearing samples (wehrlite and clinopyroxenite) were selected for trace element analysis of Cpx grains using a LA HR ICP-MS. The data show a negatively sloped normalized pattern of REE; low contents of light REE (0.1-0.3 of the primitive mantle values) and similar concentrations of middle to heavy REE (1-2 of the primitive mantle values). Extended trace element patterns of Cpx are similar between two samples and also to that of the bulk rocks, with low Nb and Zr and high fluid-mobile elements. The Y and heavy REE patterns of Cpx do not show anomalies between the samples. As these elements would be preferentially incorporated into garnet, the lack of anomalies indicates early crystallization of Cpx and later

    Gold-rich adularia-sericite-type mineralization occurs near the southern margin of the San Luis caldera, at the intersection of the Equity fault and the northern extension of the Amethyst fault system. Mineralized rock is confined primarily to steeply dipping structures in silicified rhyolite and dacite. Intense sericitic alteration occurs at higher levels in the vein system, and wall rock adjacent to some veins is bleached. The ores are multiply brecciated, and vein filling locally shows sedimentary textures.

  2. Geochemistry of jadeitites and jadeite-lawsonite rocks in a serpentinite mélange (Rio San Juan Complex, northern Dominican Republic): Constraints on fluid composition in a subduction channel environment

    Jadeitites are excellent rock types for obtaining information on fluid composition in subduction zones. Recent studies indicate that many jadeitites appear to have formed by direct precipitation from a fluid [1]. In almost all localities worldwide (see e.g. Harlow and Sorensen, 2005) jadeitites are found either as allochthonous blocks or as veins and lenses directly within the serpentinite country rock of serpentinite mélanges. In the Rio San Juan Complex on the other hand jadeitite also frequently occurs as veins (cm to some dm in thickness) within lawsonite-blueschist blocks [2,3,4] entrained in the serpentinite mélange. The mélange of the Rio San Juan Complex also contains blocks (m to 10m scale) of different metamorphic grade and lithology (eclogites, blueschists, orthogneisses and very low grade rocks) showing contrasting but interrelated P-T-t paths. The consistency of such interrelated P-T-t paths with those obtained by numerical models led Krebs et al. [5] to interpret the mélange of the Rio San Juan Complex as a former subduction channel. So far, two types of jadeitite have been found in the blueschist blocks: either as discordant veins cutting the foliation, or as concordant layers. In some cases the jadeitites contain large amounts of lawsonite and should then better be called jadeite-lawsonite rocks. The latter rock type may form a network of thin (contact between vein and host rock is very sharp and petrographically no sign of a depletion zone near the vein can be recognized, indicating that the infiltrating fluid originated from an external source and was not released from the adjoining host rock. A mineralogical center-to-rim zonation has been identified in the jadeitite veins. Near the contact to the blueschist, lawsonite is the dominant mineral phase and towards the center the amount of jadeite increases. Major and trace element concentrations also change from centers to rims. Ca/Na varies from 0.75-0.77 in the center to 1.03-1.29 in the rim

The main threat to this species is fishing. Discopyge tschudii is noncommercial and individuals caught are discarded on board. The present study analyzes the distribution and the morphological and reproductive characteristics of this ray in San Matías Gulf (SMG, Argentina. A total of 1087 individuals were analyzed. The species presented an aggregate distribution, with the main concentrations in the northern and eastern areas of SMG, at depths below 100 m. Males ranged from 9 to 43 cm and females from 11 to 38 cm. The species presented sexual dimorphism. Males were larger and heavier than females and also matured at larger sizes. Size at 50% of maturity was estimated at 30 cm for males and 21 cm for females. A total of 199 embryos were sampled and the proportion of sexes showed no significant differences from the expected 1:1. The number of embryos per female varied from 1 to 12. The most frequent values were 2 and 5. Length at birth was estimated at 82.17 ± 3.87 mm. Based on our findings, we hypothesize that the electric ray D. tschudii completes its reproductive cycle in SMG.

    Traditionally, it was assumed that major spawning activity of Illex argentinus occurs in discrete pulses along the outer-shelf/slope off Argentina/southern Brazil during late-fall/winter and that early life stages develop near the Brazil-Malvinas Confluence (BMC). However, a novel hypothesis of the population structuring of the species was proposed that states that coastal waters may be important as spawning and feeding grounds. Here, we analyzed the spatial distribution of Illex argentinus inside San Matias Gulf based on the position of the CPUE of jiggers in order to improve the knowledge of the population structuring in coastal regions. Squids were mainly concentrated on the northern region of the gulf where favorable oceanographic conditions (e.g. water stratification, chlorophyll-a concentration peaks) to feeding and spawning are present. These results provided empirical evidences that individuals of I. argentinus use Argentinean coastal waters, particularly San Matias Gulf, as permanent feeding and spawning grounds which supports the new hypothesis.

    The report describes the geology and coal deposits of the southwestern part of the San Juan Basin, N.Mex. The field lies northeast of the town of Gallup, on the Atchison, Topeka & Santa Fe Railway, and is an irregular tract of about 630 square miles in central and west-central McKinley County; it includes the southeast corner of the Navajo Indian Reservation. Settlement is confined to the white families at a few trading posts and the Indian agency at Crown Point and to scattered Navajo Indians. The land forms, drainage, vegetation, and climate are those typical of the highland in the semiarid Southwest.The investigation disclosed complicated relations of the Mancos shale and the Mesaverde formation, of Upper Cretaceous age, and a marked variation in the stratigraphic boundary between them. At the western edge of the field, as in the adjoining Gallup coal district, the Mancos consists of about 725 feet of marine shale almost wholly of Benton (lower Colorado) age. It is overlain by about 1,800 feet of chiefly estuarine and fluviatile deposits that represent the lower part of the Mesaverde formation. In ascending order the Mesaverde here consists of the Gallup sandstone member (which includes local lenses of valuable coal), the Dilco coal member, the Bartlett barren member, the Gibson coal member, and the Allison barren member. Eastward through the field the outcrops extend obliquely across the trend of old shore lines out into the ancient basin of marine deposition, and some of the beds consequently show a progressive lateral change into rocks of littoral and marine types. The Gallup sandstone member is in part replaced by marine shale of the Mancos. The upper part of the Dilco coal member is replaced by the Dalton sandstone member, and still farther east the bottom of the Dalton and the top of the remaining Dilco are replaced by the Mulatto tongue of the Mancos shale. The Bartlett barren member becomes coal-bearing and thus merges with the Gibson. The Gibson coal

    Full Text Available Low-sulfidation epithermal base-metal sulfide-rich deposits, La Carolina gold-bearing district,San Luis, Argentina. La Carolina gold-bearing district is located at the western end of the Metallogenetic Belt of San Luis, which is spatially and genetically related to the mesosilicic volcanism of mio-pliocene age. The volcanic arc experienced an eastward migration, due to the flattening of the Nazca plate in the segment 27°-33°S, known as the Pampean flat-slab. At La Carolina, the volcanic activity occurred between 8.2 and 6.3 Ma. It encompasses lavas and pyroclastics of andesitic, dacitic, latitic and trachytic composition. The mesosilicic magmas belong to normal to high-k calc-alkaline and shoshonitic suites. Structural analysis shows that previous structures have strongly controlled the emplacement of volcanic rocks and related mineral deposits at La Carolina allowing to define a pullapart.In this gold-bearing district there are eigth small mineralized prospects. The mineralogy consists of pyrite, arsenic rich pyrite, galena, sphalerite, marcasite, melnikovite, chalcopyrite, pyrrhotite, arsenopyrite, tennantitetetrahedrite, digenite, covellite, bornite, pyrargiryte, hessite, silvanite, pearceite, argirodite, gold, silver, greigite, boulangerite, jamesonite and electrum. The gangue consists of quartz, calcite, chalcedony and minor adularia.The hydrothermal alteration is widespread and comprise phyllic and argillic mineral assemblages characterized by sericite, illite, interstratified I/S, and silicic; propylitic alteration is also present as an outer halo. Fluid inclusions studies show that the formation temperatures range between 230º to 330º C. Boiling and mixing with meteoric water led to mineral precipitation. Based on the mineralogy, textures, hydrothermal alteration, formation temperatures,fluid chemistry and prospective geochemistry the mineralizations have been classified as low-sulfidation epithermal base-metal sulfide-rich deposits.

    Full Text Available El Gran San Miguel de Tucumán, la ciudad intermedia más importante del Noroeste Argentino, atravesó un acelerado crecimiento poblacional junto a un proceso de expansión de la pobreza, que se hizo significativo durante los primeros años del siglo XXI. El devenir de la agroindustria azucarera -principal actividad económica de la provincia- y las políticas económicas de corte neoliberal implementadas en las tres últimas décadas del siglo XX incidieron, entre otros, sobre dicho proceso. En este contexto se seleccionó una de las áreas de mayor incidencia de la pobreza del aglomerado - el barrio denominado Juan Pablo II-, para indagar las características que asumen sus privaciones, los factores estructurales y la intervención del Estado en este entramado de persistencias de la pobreza. Se utilizan como fuentes de información el Censo Nacional de Población, Hogares y Viviendas de los años 2001 y 2010, y las respuestas de entrevistas semiestructuradas, realizadas a una muestra de hogares en dicho barrio. Los resultados evidencian las dificultades estructurales de la población estudiada para superar las condiciones de pobreza frente a las restricciones del mercado de trabajo y la ausencia de políticas habitacionales. El Estado se hace presente -como resultado de las críticas condiciones de vida y la demanda de sus habitantes- mediante distintos programas, que no revierten el deterioro social, sino que sólo consiguen la satisfacción de umbrales mínimos de necesidad.

    Chiapella, Jorge O.; Demaio, Pablo H.

    2015-01-01

    Abstract We compiled a checklist with all known endemic plants occurring in the Sierras of Córdoba and San Luis, an isolated mountainous range located in central Argentina. In order to obtain a better understanding of the evolutionary history, relationships and age of the regional flora, we gathered basic information on the biogeographical and floristic affinities of the endemics, and documented the inclusion of each taxon in molecular phylogenies. We listed 89 taxa (including 69 species and 20 infraspecific taxa) belonging to 53 genera and 29 families. The endemics are not distributed evenly, being more abundant in the lower than in the middle and upper vegetation belts. Thirty-two genera (60.3%) have been included in phylogenetic analyses, but only ten (18.8%) included local endemic taxa. A total of 28 endemic taxa of the Sierras CSL have a clear relationship with a widespread species of the same genus, or with one found close to the area. Available phylogenies for some taxa show divergence times between 7.0 – 1.8 Ma; all endemic taxa are most probably neoendemics sensu Stebbins and Major. Our analysis was specifically aimed at a particular geographic area, but the approach of analyzing phylogenetic patterns together with floristic or biogeographical relationships of the endemic taxa of an area, delimited by clear geomorphological features, could reveal evolutionary trends shaping the area.

    The reproductive cycle of Trophon geversianus (Pallas 1774) population from Golfo San José (Chubut, Argentina, 42°33'S, 64°33'W) was studied using histochemical methods and digital image analysis. For such purpose, ovary samples were taken monthly between July 2006 and August 2007 and stained with hematoxylin and eosin, Sudan black B (to identify lipids) or Schiff's ninhydrin (to identify proteins). Four different gametogenic stages were described: oogonias, previtellogenic oocytes, early vitellogenic oocytes, and late vitellogenic oocytes. Two spawning events were registered; one between September and October 2006, and a second one between February and March 2007. Oocyte quality was determined by the changes in lipid and protein composition during gametogenesis. Through digital image analysis, a lipid and a protein indexes (LI and PI) were calculated. Significant differences were observed in LI over month sampled, contrarily to what PI showed. A significant and positive correlation was found between lipid and protein content and oocytes areas, indicating that these nutrients accumulate during the entire vitellogenesis. Also, when dividing the oocytes into two size groups, analysis indicates a positive correlation between LI and oocyte area for smaller area oocytes. This demonstrates that while proteins accumulate linearly throughout vitellogenesis process, lipids accumulate in two steps: first at a growing rate, secondly at constant rate. This information is essential to determine the nutritional requirements of brood stock individuals at hatcheries in this potential fishery resource that inhabits patagonian waters.

    Commerson's dolphins (Cephalorhynchus commersonii) inhabit coastal waters of Southern South America and Kerguelen Islands. Limited information exists about the acoustic repertoire of this species in the wild. Here, echolocation signals from free-ranging Commerson's dolphins were recorded in Bahía San Julián, Argentina. Signal parameters were calculated and a cluster analysis was made on 3180 regular clicks. Three clusters were obtained based on peak frequency (129, 137, and 173 kHz) and 3 dB bandwidth (8, 6, and 5 kHz). The 428 buzz clicks were analyzed separately. They consisted of clicks emitted with a median inter-click interval of 3.5 ms, peak frequency at 131 kHz, 3 dB bandwidth of 9 kHz, 10 dB bandwidth of 18 kHz, and duration of 56 μs. Buzz clicks were significantly shorter and with a lower peak frequency and a broader bandwidth than most of the regular clicks. This study provided the first description of different echolocation signals, including on- and off-axis signals, recorded from Commerson's dolphins in the wild, most likely as a result of animals at several distances and orientations to the recording device. This information could be useful while doing passive acoustic monitoring.

Materiales y Métodos: estudio cuantitativo con diseño descriptivo. La información se obtuvo a través de un cuestionario diseñado y modificado por las investigadoras y autoadministrado por los estudiantes de siete instituciones públicas de educación media jornada de la mañana. La población estuvo conformada por 5537 adolescentes entre las edades de 10 a 17 años, se realizó un muestreo probabilístico aleatorio simple y a través de la afijación proporcional se tomó una muestra de 774 estudiantes. Resultados: se encontró que los lugares con mayor prevalencia donde se presenta el tipo de agresión entre estudiantes son: cerca al colegio, al salir de clase, al interior del aula cuando no está el profesor y por último en pasillos y baños. El tipo de agresión más frecuente es la verbal, que por lo general se origina cuando se habla mal de la persona o por decir palabras ofensivas; las patadas, golpes y peleas entre grupos como tipo de agresión física no reportaron una frecuencia alta entre los adolescentes. Conclusión: el matoneo continúa presente en las instituciones de educación media convirtiéndose en una problemática social que ha sido tratada por diferentes sectores con el fin de encontrar una solución, pero los esfuerzos no están dando resultados; por ello, se debe continuar fortaleciendo el diseño de estrategias e implementación de modelos de convivencia sana orientadas a padres, educadores y estudiantes para la solución de conflictos y comprensión de consecuencias.

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

    Full Text Available Desde principios de la década de los 80, el sensor AVHRR a bordo de los satélites NOAA ha provisto de estimaciones de la temperatura de la superficie del mar (TSM a la comunidad científica en general. Hacia finales de la década de los 90, surge una nueva generación de radiómetros que combinan una mayor gama de mediciones espectrales con mejoras en la tecnología, como lo es el sensor  MODIS a bordo de los satélites Terra y Aqua. El desarrollo de este último sensor se basó en los años de trayectoria de la serie NOAA/AVHRR. La comprensión de la relación entre los productos derivados de distintos sensores es fundamental para el seguimiento continuo a largo plazo de cualquier variable y de la construcción de serie de tiempos combinados. El objetivo del presente trabajo fue realizar una comparación de los valores mensuales de TSM para el período 2003-2006 calculadas a partir de datos de la serie NOAA/AVHRR vs Aqua/MODIS sobre un sector de la Plataforma Continental Argentina frente al Golfo San Jorge. El análisis de las isotermas muestra un patrón de distribución similar durante todos los meses para ambos sensores. El coeficiente de correlación de Pearson tanto en el análisis estacional como mensual fue alto (> 0,8. El análisis comparativo de la temperatura medida en ambos sensores muestra que los productos de TSM son similares, teniendo en cuenta que la diferencia media de temperatura entre ambos sensores es inferior a 0,5ºC. Por lo tanto, para el estudio de largas series de tiempo de TSM en la plataforma continental argentina se puede utilizar en forma continua las mediciones de Aqua/MODIS, cuando ya no se disponen las de NOAA/AVHRR.

    Full Text Available This abbey is organised in two main zones, one to the south east, consisting of the monastic and ecclesiastical buildings, and another to the north west, comprising the school. The church, the library and the offices are located at the convergence of the two zones. The abbey church is the outstanding feature of the whole project, and it can accommodate 1580 people as well as 360 monks in the choir. The church has been designed around the axis baptistery-altar, the latter occupying a central, separate position, and constituting the focal point of the design. The sacristy forms a link between the monastery and the church. Below the main church there is a small parish crypt with 150 seats, and a chapel for the brethren, seating 104 people, as well as a series of 34 private chapels for the monks to celebrate Mass. The construction of the project features the use of folded reinforced concrete shells for walls and roofs. The types of materials mainly adopted, bare concrete, brick, granite and oak, express the austerity of monastic life. The campanile —a thin slab resting on parabolic supports— is a symbol of our gase towards the world beyond. The church building seeks to identify closely form and function, and is noteworthy also in the choice of spatial and structural Rythm as well as for the wealth of subtle details which it incorporates.En la organización general del conjunto se aprecian dos zonas: la SE., dedicada a los edificios monásticos y eclesiásticos, y la NO., a los edificios escolares. La iglesia, la biblioteca y las oficinas se sitúan en el encuentro de estas dos zonas. El complejo se centra alrededor de la iglesia de la abadía, capaz de albergar una congregación de 1.580 personas y en cuyo coro se prevé espacio para 260 monjes y hermanos. La iglesia, ha sido diseñada alrededor del eje sacramental, baptisterio-altar, el cual aparece en situación central exento, como punto focal. El coro está dividido en dos mitades. La sacristía sirve como articulación para unir el ala del monasterio y la iglesia. Debajo de ésta hay una parroquia, con 150 asientos, la capilla de los hermanos para 104, y una serie de 34 capillas privadas para celebrar la Santa Misa. La construcción ha sido realizada a base de láminas plegadas de hormigón en paredes y techos; y los materiales empleados, hormigón visto, ladrillo, granito y madera de roble, son expresión de la austeridad de la vida monástica. El campanario —una delgada losa en cantiléver sobre soportes parabólicos —constituye el símbolo de un mirar hacia el más allá. El edificio de la iglesia se caracteriza por la identificación entre forma y contenido, el acierto en la elección del ritmo del espacio y estructura, y por los infinitos matices que nos ofrece.

This chapel does not pretend to be an original design, or even a especially original structure. It must be interpreted rather as a shape that follows logically from the attempt to serve a spiritual need of man in a popular language. In this case, the architecture has been understood as something alive and changing, under the effects of light and shade. The plastic quality of this church induces an emotional uplift to those who look at it from the neighboring fields.El organismo arquitectónico está formado, esencialmente, por tres partes: una galería procesional de ingreso y el baptisterio, a la izquierda de la entrada principal, y la gran nave a la derecha; entre estos dos cuerpos existen dos pequeños claustros. Al proyectar esta iglesia no se ha tenido la pretensión de diseñar una forma nueva o de pensar en estructuras originales, sino que «la forma» resultante es una consecuencia lógica de la premisa fundamental: «servir a los hombres» en un lenguaje «popular». La arquitectura ha sido tratada, en este caso, como algo vivo y cambiante bajo los efectos de la luz, de la sombra, de las estaciones. La plástica de su forma orgánica imprime una sublime emoción al que la contempla desde la campiña circundante.

    Full Text Available Este artículo analiza la prolongación del Ferrocarril Central Norte entre 1880-1885, época en que la línea se extendió desde la ciudad de San Miguel de Tucumán hasta el límite con Salta. Propone, a partir del análisis del caso tucumano, problematizar algunos aspectos del eje vincular entre el ferrocarril y la tierra. En este sentido, la provincia de Tucumán mostraba un proceso singular de apropiación del recurso tierra en relación con muchas otras regiones de Argentina en el siglo XIX, lo que habría pautado también las políticas diseñadas para la obtención de tierras necesarias para la construcción de ferrocarriles. Finalmente, en torno a la cuestión ferrocarriles e intereses económicos empresariales sostiene que, pese a que en los balances finales las inversiones de capitales privados y públicos hayan resultado favorables a determinados sectores, fueron secundadas por actores ligados a una diversidad de actividades económicas.This article reviews the expansion of the "Central Norte" railway between 1880 and 1885. During this period of time, it stretched from the city of San Miguel de Tucumán up to the border of the Province of Salta. We intend to discuss the linking core between railway and land by analyzing this case. In this way, the Province of Tucumán shows a particular process of appropriation of the land with regard to many other regions of the country during the XIX th century. This should have lined the designed politics for the obtention of the necessary lands for the railway construction. Finally, and according to railway and economic business interests, we uphold that, despite the final positive balances of some private and public investments, they have been supported by agents related to a variety of economic activities.

    Full Text Available Shiga toxin producing Escherichia coli (STEC, Salmonella spp., and Yersinia species was investigated in humans, animals, and foods in San Luis, Argentina. A total of 453 samples were analyzed by culture and PCR. The antimicrobial susceptibility of all the strains was studied, the genomic relationships among isolates of the same species were determined by PFGE, and the potencial virulence of Y. enterocolitica strains was analyzed. Yersinia species showed higher prevalence (9/453, 2.0%, 95% CI, 0.7–3.3% than STEC (4/453, 0.9%, 95% CI, 0–1.8% and Salmonella spp. (3/453, 0.7%, 95% CI, 0–1.5%. Y. enterocolitica and Y. intermedia were isolated from chicken carcasses (6/80, 7.5%, 95% CI, 1.5–13.5% and porcine skin and bones (3/10, 30%, 95% CI, 0–65%. One STEC strain was recovered from human feces (1/70, 1.4%, 95% CI, 0–4.2% and STEC stx1/stx2 genes were detected in bovine stools (3/129, 2.3%, 95% CI, 0–5.0%. S.

    Full Text Available Se estudió la morfología de un campo de dunas submarinas desarrollado en una entrada de marea que conecta la plataforma continental argentina con bahía Anegada (sur de la provincia de Buenos Aires. Se infiere la circulación sedimentaria a partir del desplazamiento diferencial de las geoformas medido en relevamientos consecutivos. Como parte de la metodología se utilizó un ecosonda y un sistema batimétrico por medición de fase (SBMF denominado GeoSwath que permitieron obtener la morfología submarina en detalle. Se observaron dunas grandes sobre el límite sur del campo de dunas con altura entre 4,5 y 5,0 m y espaciamiento entre 100 y 120 m, a profundidades de 24 m, que se desplazan hacia el exterior del canal a una rapidez entre 18 y 75 m año-1. Hacia el límite norte del campo, a 21 m de profundidad las dunas eran de menor magnitud, entre 2,0 y 2,5 m de altura y espaciamiento entre 40 y 80 m, y se desplazaron a una rapidez entre 18 y 36 m año-1 hacia el interior de bahía Anegada. Se obtuvo la distribución del flujo de agua en toda la columna, en un perfil perpendicular al canal relevado, mediante ADCP. Los valores máximos de rapidez de corriente fueron durante la marea creciente, alcanzando 2,0 m s-1. Los resultados obtenidos permiten definir un modelo circulatorio de transporte de sedimentos arenosos, con la formación de un delta de marea de flujo en la cabecera de la entrada de marea y un delta de reflujo en el límite del dominio oceánico, unidos por una garganta de marea profunda, exenta de sedimentos inconsolidados.The morphology of a submarine dune field developed in a tidal inlet that connects the Argentinean continental shelf with Anegada Bay (southern Buenos Aires province was studied.

    Full Text Available AIM: The use of biological indicators of pollution has increased in recent years as an alternative to the monitoring of water quality. Phytoplankton community selectively respond to different anthropogenic disturbances, such as water dams and the increase of nutrients coming from city centers, which leads to the eutrophication of the aquatic environment. The objective of this work was to evaluate the composition and the structure of the algal and Cyanobacterial communities in order to prove human influences by the presence of reservoirs with some degree of eutrophication and the impact of urbanization in two rivers at the Bebedero basin in San Luis province (Argentine. METHODS: Four sites were sampled: two of them were placed before dams and villages (V1 and (P1 and two after them (V2 and (P2. Each site was visited in every season of the year: summer, autumn, winter and spring. Qualitative and semi-quantitative phytoplankton samples were taken, and the frequency of occurrence was determined. Variations between pairs of sampling stations were analyzed through the Jaccard similarity and complementarity indices. RESULTS: Ninety two taxa were identified, of which diatoms were the most frequent. The most affected station was P2 with high abundance, less diversity and equitability, whereas the species more tolerant to the presence of organic matter were Melosira varians, Navicula tripunctata, Oscillatoria limosa, Gomphonema parvulum and Coelastrum microporum, and some species of euglenophytas. CONCLUSION: Therefore, the structure and composition of the algal and Cyanobacterial communities allowed us to identify sections more sensitive to human-induced alterations.

    Full Text Available RESUMEN: Organizar racionalmente los cientos de títulos dedicados a la Lengua de Italia de la orden de San Juan publicados entre los siglos XVI y XX resulta complicado, siendo más útil una aproximación cronológica. El principal punto de referencia se sitúa en las historias generales clásicas del siglo XVI ampliamente documentadas, con espíritu aristocrático y laudatorio hacia la orden (Giacomo Bosio, 1594-1602, Bartolomeo Dal Pozzo, 1589 continuadas en el XVIII (Giandonato Rogadeo, 1782, que culminan con Paolo Maria Paciauli (1780, autor de una construcción teórica que desde la Edad Media delineaba los rasgos de la civilización de la Europa católica. La idea de que los caballeros de la orden de Malta encarnaban los principios espirituales y aristocráticos exigibles a la nobleza italiana destinada al gobierno de las distintas unidades políticas de la península itálica, queda reflejada en muchos escritos de estos siglos. Por otra parte, la defensa de privilegios y derechos propios, junto a las relaciones de los hechos de armas, especialmente de las naves maltesas, y los ruoli o listados de caballeros y sus dignidades, constituyen una parte importante de las ediciones relativas a la orden. Tras casi haber desaparecido su poder político en el siglo XIX, y manteniéndose una línea historiogràfica centrada en aspectos heráldicos y genealógicos, ha sido preciso esperar hasta fines del siglo XX para que la historiografía académica ponga sus ojos en unos archivos preciosos para el estudio del mundo rural, de las relaciones de poder y otros muchos aspectos descuidados en las historias tradicionales de la orden de Malta.ABSTRACT: The essay of a rational organization of hundreds of titles devoted to Tongue of Italy of the Order of Saint John of Jerusalem is a difficult task, and a chronological approach seems to be more useful.

    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.

    An extensive series of high-resolution satellite images from the advanced very high-resolution radiometer (AVHRR) and the sea-viewing wide field-of-view sensor (SeaWIFS) was used in a synoptic oceanographic characterization of San Jorge Gulf (SJG, Argentine Patagonia), an area of great significance for marine conservation and commercial fishing. Remotely sensed information was combined with on-board observer's data and published information to investigate the role of distinctive oceanographic features in relation to the life cycle of the Patagonian red shrimp (Pleoticus muelleri), main target of the industrial fleet in SJG. Three frontal systems-North, South and Outer SJG-are characterized. The North and South SJG fronts are associated with shrimp reproductive aggregations during late spring and summer. While both function as spawning/nursery grounds, they differ from each other in many respects. The thermohaline South SJG front has its maximum expression during the winter, reflecting the influence of the low-salinity Magellanic Plume, while the thermal North SJG front develops during spring and summer as the water column becomes stratified in the central basin of the gulf. Wind-related down-welling inshore of the front prevails in the North SJG, and upwelling in the South SJG frontal area. Chlorophyll a is concentrated near the thermocline on the stratified side of the North SJG, and for that reason, it is not detected by remote sensors during the spring bloom and the summer but becomes apparent offshore from the location of the front when the thermocline deepens during the fall (May). In the South SJG front, Chl-a concentration is apparent inshore from the front all year-round, related in part to upwelling-mediated resuspension. The northern end of the outer front coincides in time and space with a recurrent non-reproductive aggregation of red shrimp between November and January and is presumably related to foraging. It is argued that keeping the North and South

  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.

    Full Text Available In this study, a total of 24 Listeria spp. strains were analyzed. Twenty-two isolates were obtained in San Luis (Argentina from human, animal, and food samples. Two types of strains, Listeria monocytogenes CLIP 22762 and Listeria innocua CLIP 74915, were included as reference strains. All isolates were biochemically identified and characterized by serotyping, phage typing, and amplification of the flaA gene by polymerase chain reaction (PCR. Repetitive intergenic consensus (ERIC sequence-based PCR was used to generate DNA fingerprints. On the basis of ERIC-PCR fingerprints, Listeria spp. strains were divided into three major clusters matching origin of isolation. ERIC-PCR fingerprints of human and animal isolates were different from those of food isolates. In addition, groups I and II included ten L. monocytogenes strains, and only one Listeria seeligeri strain. Group III included nine L. innocua strains and four L. monocytogenes strains. Computer evaluation of ERIC-PCR fingerprints allowed discrimination between the tested serotypes 1/2b, 4b, 6a, and 6b within each major cluster. The index of discrimination calculated was 0.94. This study suggests that the ERIC-PCR technique provides an alternative method for the identification of Listeria species and the discrimination of strains within one species.En este estudio se analizaron 24 cepas de Listeria spp. De ellas, 22 fueron obtenidas en San Luis (Argentina, a partir de muestras humanas, de animales y alimentos.

    Science.gov (United States)

    Pérez de Rosas, A R; Segura, E L; García, B A

    2011-01-01

    Triatoma infestans is the main vector of Chagas' disease in South America between latitudes 10°S and 46°S. A multilocus microsatellite data set of 836 individuals from 27 populations of T. infestans, from all its range of distribution in Argentina, was analyzed. Our results favor the hypothesis of two independent migration events of colonization in Argentina and secondary contacts. The majority of the populations of the western provinces of Catamarca, La Rioja, San Juan and the west of Cordoba province, had almost no shared ancestry with the rest of the populations analyzed. Probably those populations, belonging to localities close to the Andean region, could have been established by the dispersal line of T. infestans that would have arrived to Argentina through the Andes, whereas most of the rest of the populations analyzed may have derived from the dispersal line of T. infestans in non-Andean lowlands. Among them, those from the provinces of Formosa, Chaco, Santiago del Estero and Santa Fe shared different percentages of ancestry and presented lower degree of genetic differentiation. The migratory movement linked to regional economies and possibly associated with passive dispersal, would allow a higher genetic exchange among these populations of T. infestans. This study, using microsatellite markers, provides a new approach for evaluating the validity of the different hypotheses concerning the evolutionary history of this species. Two major lineages of T. infestans, an Andean and non-Andean, are suggested. PMID:21224874

    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.

    Full Text Available The study area is located in the center west of the county of Tucumán, in the NW of Argentina. It extends from the oriental border of San Javier’s mountain between the towns of Yerba Buena and Manantial. In the piedmont zone and plain, have settled down diverse urban, agricultural centers and an important industrial complex that are supplied by underground water. The objective of this paper is to define the different geologic factors that impact in the behavior of the underground water and to define areas with appropriate hydrogeological characteristics for its use. The investigation determined that the water contained in the aquifers is of good quality and due to the high permeability, important flows can be obtained, that guarantee the supply to the population, agriculture and industry.La zona de estudio está ubicada en el centro oeste de la provincia de Tucumán, en el noroeste de Argentina. Se extiende desde el borde oriental de la sierra de San Javier entre las localidades de Yerba Buena y el Manantial. En el piedemonte y llanura se han establecido diversos centros urbanos, agrícolas y un importante complejo industrial que se abastecen de agua subterránea. El objetivo del trabajo es delimitar los distintos factores geológicos que inciden en el comportamiento del agua subterránea y tratar de definir zonas con características hidrogeológicas apropiadas para su aprovechamiento. De esta investigación se determinó que el agua que contienen los acuíferos es de buena calidad y debido a la elevada permeabilidad de los mismos, se pueden obtener importantes caudales, con lo que se garantiza el abastecimiento a la población, agricultura e industria.

    Full Text Available La presencia de africanos en la argentina continúa siendo hoy en día un tema en discusión y continua elaboración. Negada, silenciada  y en el mejor de los casos minimizada dentro de los discursos oficiales de la configuración de la nación, esta ausencia fue tal que la misma se trasladó y arraigó hasta en la propia memoria e imaginario colectivo de los argentinos. En los últimos años surgieron diversos estudios académicos motivados a reivindicar la verdadera historia de los afro y afro argentinos así como la incidencia e importancia que los mismos tuvieron en los diferentes procesos históricos del país.  En este caso presentamos un avance  acerca de las tareas de investigación realizadas hasta el momento, las cuales se enmarcan en el proyecto de pos graduación en memoria social y patrimonio cultural de la UFPEL, el cual se basa en el estudio del patrimonio material  africano, como herramienta de visibilización y revalorización de la historia de dicha población contextualizando el área de estudio  en la ciudad colonial de San Miguel de Tucumán, situada en  la región noroeste de Argentina.

We present preliminary results of the petrologyand geochemistry of Cretaceous basalts exposed in the anticlines of the sierra of Las Quijadas and cerrillada ofLas Cabras. In the mountainous western of San Luis crop out at least two depositional sequences which togetherexceed the 1500 m thick and consists mainly of clastic sedimentary sequences typical continental red beds belongingto the Giant Group and Lagarcito Formation. Within this group, recognizes two types of basalt events, representedby lava flows and dykes. The lava flows were described in the northeastern sector of the anticline, in a landscapeof gentle hills. The dykes were found on the western flank of the anticline, northern sector of that mountain.Basalt lava flows have porphyritic texture with phenocrystals show idiomorphic olivine with clinopyroxene,amphibole and plagioclase, while the basaltic dykes show olivine in porphyritic texture embedded in a plagioclasepaste without orientation, amphibole and apatite needles. The basalts of the cerrillada de Las Cabras presented asa volcanic breccia associated with basaltic bombs. They have phenocrystals of olivine and clinopyroxene in pastewith plagioclase oriented. The basalts are classified as alkali basalts and related to intraplate basalts. When analyzingrare earth elements chondrite normalized according to Nakamura’s design are observed with a steep negative slopefor the heavy rare earth elements, a design that is similar to that found in alkaline basalts from the Sierra Chica deCórdoba.

    Full Text Available Abstract This study aimed to investigate the diet of the gecko Homonota fasciata (Duméril & Bibron, 1836 in a population from Monte of San Juan Province, Argentina, and to analyze possible temporal, sexual, and ontogenetic variations in feeding behavior. We determined the total volume, number, and occurrence frequency of each prey item and calculated the relative importance indexes. We also assessed trophic diversity and trophic equity. Homonota fasciata had a generalist and diverse diet based on arthropods, including insects and arachnids. Individuals adopted a passive 'sit and wait' foraging strategy. There were seasonal-, sex-, and age-related variations in the trophic spectra. The results of this study provide a valuable contribution to our understanding of the biology of this species, with implications for the establishment of management guidelines both for the species and its habitat.

    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 Mancos-Menefee Composite Total Petroleum System (TPS) includes all genetically related hydrocarbons generated from organic-rich shales in the Cretaceous Mancos Shale and from carbonaceous shale, coal beds, and humate in the Cretaceous Menefee Formation of the Mesaverde Group. The system is called a composite total petroleum system because the exact source of the hydrocarbons in some of the reservoirs is not known. Reservoir rocks that contain hydrocarbons generated in Mancos and Menefee source beds are found in the Cretaceous Dakota Sandstone, at the base of the composite TPS, through the lower part of the Cliff House Sandstone of the Mesaverde Group, at the top. Source rocks in both the Mancos Shale and Menefee Formation entered the oil generation window in the late Eocene and continued to generate oil or gas into the late Miocene. Near the end of the Miocene in the San Juan Basin, subsidence ceased, hydrocarbon generation ceased, and the basin was uplifted and differentially eroded. Reservoirs are now underpressured.

    Full Text Available This study presents a synthesis on the geology of the crystalline complex that constitute the Sierra de la Aguada, San Luis province, Argentine, from an approach based on field relations, petrologic and structural features and geochemical characteristic. This mountain range exposes a basement dominated by intermediate to mafic calcalkaline igneous rocks and peraluminous felsic granitoids, both emplaced in low to medium grade metamorphic rocks stabilized under low amphibolite facies. All this lithological terrane has been grouped in the El Carrizal-La Aguada Complex. Field relations, petrographic characterization and geochemical comparison of the plutonic rocks from the study area with those belonging to the Ordovician Famatinian suit exposed in the Sierra Grande de San Luis, suggest a genetic and temporal relation linked to the development of the Famatinian magmatic arc.

    Full Text Available Through its history, one can see traces of African roots in the popular cult of San Baltazar in Argentina. In spite of starting as an imposed devotion by the clergy and the Spanish Crown to the slaves in the middle of 18th Century, early the later could insert their own cultural traditions, producing a sort of sui generis syncretism.Now days, those traditions are present in some religious ceremonies, especially in the devotional area. So far they consider that he is the patron saint of the joy and fun, they celebrate him with music and dance, being some of them from black roots. In this paper I wish to analyze one of these religious principles. So far there isn't any difference between kings and goods, the divine personality has a bipolar behavior that comes to real in a unique entity movable-non movable, thing- human. In this way, being goods also kings and kings also goods, their divine and royal attributes are object of devotion and subordination by their faithful people-subjects. My hypothesis is that that black people could have applied this principle so far they knew that double characteristic of this saint: divine (he is a saint and royal (he is one of the three Wise Men, compatible with their ancestral believes.//Al revisar la historia del culto popular de San Baltazar en Argentina, es posible encontrar sus raíces africanas.

    The Cerro Negro district, within the Argentinian Deseado Massif province, has become one of the most significant recent epithermal discoveries, with estimated reserves plus resources of ˜6.7 Moz Au equivalent. The Marianas-San Marcos vein system contains about 70 % of the Au-Ag resources in the district. Mineralization consists of Upper Jurassic (155 Ma) epithermal Au- and Ag-rich veins of low to intermediate sulfidation style, hosted in and genetically related to Jurassic intermediate composition volcanic rocks (159-156 Ma). Veins have a complex infill history, represented by ten stages with clear crosscutting relationships that can be summarized in four main episodes: a low volume, metal-rich initial episode (E1), an extended banded quartz episode with minor mineralization (E2), a barren waning stage episode (E3), and a silver-rich late tectonic-hydrothermal episode (E4). The first three episodes are interpreted to have formed at the same time and probably from fluids of similar composition: a 290-230 °C fluid dominated by meteoric and volcanic waters (-3‰ to -0‰ δ18Owater), with sulfur (-1 to -2 ‰ δ34Swater). Metal was mainly precipitated at the beginning of vein formation (episode 1) due to a combination of boiling at ˜600 to 800 m below the paleowater table, and associated mixing/cooling processes, as evidenced by sulfide-rich bands showing crustiform-colloform quartz, adularia, and chlorite-smectite banding. During episodes 2 and 3, metal contents progressively decrease during continuing boiling conditions, and veins were filled by quartz and calcite during waning stages of the hydrothermal system, and the influx of bicarbonate waters (-6 to -8.5 ‰ δ18Owater). Hydrothermal alteration is characterized by proximal illite, adularia, and silica zone with chlorite and minor epidote, intermediate interlayered illite-smectite and a distal chlorite halo. This assemblage is in agreement with measured fluid inclusion temperatures. A striking aspect of the

    The processes regulating the relationship between tidal flows and shallow groundwater dynamics, temperature and salinity in a coastal wetland in an arid climate are analysed in a detailed field study carried out in the marsh located at Playa Fracasso (Argentina). The continuous records of groundwater level, temperature and electrical conductivity from a transect perpendicular to the coastline were studied during a period ranging from summer to winter, together with the information obtained in hydrogeomorphological field surveys and soil profiles. An assessment of the processes conditioning marsh hydrology was carried out contemplating seasonal (summer-winter) and periodical variations caused by tidal flows. The study showed that the dynamics of groundwater in relation to tidal flows depends almost exclusively on the infiltration of tidal water when the marsh is flooded during spring tides (syzygy), with an increase in the groundwater discharge level at the onset of syzygy. The differences in temperature between sea and continental water were very useful in defining the origin of the different contributions. Groundwater salinity is mainly associated with the leaching of the soil salts that enter with the sea water infiltrating during flood events. The presence of saline soils in the marsh is regulated by the evapotranspiration predominating in arid zones. The conceptual hydrological model suggested may help in the understanding of the hydrological processes in other similar marshes of Patagonia, as well as in coastal wetlands of arid zones worldwide.

    Full Text Available Por sus condiciones biofísicas, los bosques tropicales poseen gran capacidad para ofrecer servicios ecosistémicos. La Selva Paranaense, uno de los bosques tropicales lluviosos más amenazados de Sudamérica, alcanza actualmente 1.200.000 ha, conservadas fundamentalmente en Argentina y en menor medida en Brasil y Paraguay. Este trabajo propone analizar la pérdida de servicios de regulación a partir de la evaluación del proceso de deforestación y cambio de uso del suelo entre 2001 y 2011 en una cuenca binacional argentino-brasileña, la Cuenca del río San Antonio (CrSA. La superficie de dicha cuenca (117.348 ha, que forma parte del río Iguazú, se distribuye de manera semejante en ambos países. Sin embargo, la clasificación de las imágenes satelitales (Landsat 5, sensor TM revela que Argentina conserva en 2011 el 61,7% de áreas boscosas en las que predominan servicios de regulación, mientras que Brasil el 25%.

    Full Text Available The rare bismuth oxychloride, bismoclite (BiOCl, has been identified in the weathered tourmaline–cemented, magmatic–hydrothermal breccia complex at the San Francisco de los Andes Bi–Cu–Au deposit, Argentina. A wide variety of supergene minerals were detected in the oxidized zone, but only preisingerite (Bi3(AsO42O(OH is intimately associated with bismoclite. Bismuth arsenate is present either as minor accessory phases or as traces in bismoclite-rich samples. This is the first documented occurrence of bismoclite in a porphyry-related, and magmatic–hydrothermal breccia pipe deposit. Bismoclite is interpreted to have formed by weathering of hypogene bismuthinite (Bi2S3, which originally occurred with arsenopyrite to cement the breccias. These appear to have reacted with O2- and HCl-bearing meteoric waters to produce pockets of supergene bismoclite–preisingerite assemblages. Bismoclite samples have been characterized by means of X-ray diffractometry (XRD, geochemistry, petrography, scanning electron microscopy (SEM, differential thermal analysis–thermogravimetry analysis (DTA–TGA and infrared analysis (IR providing useful insights and updated information regarding this rare bismuth oxychloride and associated arsenate mineral. The San Francisco de los Andes breccia complex shows similar geometry, morphology and internal organization as those found in traditional magmatic–hydrothermal breccias associated with Cu–Mo porphyry deposits. Bismoclite and preisingerite form due to the presence of hypogene Bi-bearing minerals followed by appropriate supergene conditions. These hypogene minerals commonly occur only as trace phases, or are entirely absent, in porphyry and related magmatic–hydrothermal breccia deposits. The scarcity of hypogene Bi–mineral phases in porphyry and related magmatic–hydrothermal breccia deposits is the main reason why bismoclite has not previously been reported in these types of deposits.

    We compared biological and chemical parameters in surface waters of the Gulf of San Jorge to better understand carbon export and the factors that control phytoplankton production in an area of the Argentinian Continental Shelf, a vastly under sampled region of the SW Atlantic Ocean. In April of 2012, we estimated new and regenerated primary production in the Gulf by measuring nitrate and ammonium uptake, respectively. We also measured macronutrient, and in situ chlorophyll-a concentrations, which were compared to chlorophyll-a estimates from remote sensing. Although the Gulf of San Jorge presents high levels of chlorophyll-a and primary production, the relationship between these parameters is not straightforward. Previous studies showed that surface chlorophyll-a explains only part of the variance in euphotic-zone integrated primary production, and that satellite-derived chlorophyll-a underestimates in situ primary production. Our results showed large spatial variability in the Gulf, with transitional physico-chemical conditions, such as fronts, that could favor an increase in biological production. In situ chlorophyll-a concentrations were highest at the mid-shelf station (6.0 mg m- 3) and lowest at the northernmost location by an order of magnitude. Remote sensing measurements of chlorophyll-a underestimated our in situ chlorophyll-a concentrations. Total nitrogen (nitrate + ammonium) uptake showed relatively similar rates throughout the study area (≈ 130 nM-N d- 1), except in the northernmost station where it was much lower (53 nM-N d- 1). This north region had a distinct water mass and maximal levels of macronutrients (nitrate ≈ 6 μM, ammonium ≈ 1.2 μM, phosphate ≈ 1.2 μM and silicic acid ≈ 4 μM). For the entire sampling region, chlorophyll-a concentrations strongly correlated with total nitrogen uptake (r = 0.76, n = 8, p < 0.05) and new primary production (r = 0.78, n = 8, p < 0.05). Values of the f-ratio were 0.9 in mid-shelf, and ranged

    The San José district is located in the northwest part of the Deseado massif and hosts a number of epithermal Ag-Au quartz veins of intermediate sulfidation style, including the Huevos Verdes vein system. Veins are hosted by andesitic rocks of the Bajo Pobre Formation and locally by rhyodacitic pyroclastic rocks of the Chon Aike Formation. New 40Ar/39Ar constraints on the age of host rocks and mineralization define Late Jurassic ages of 151.3 ± 0.7 Ma to 144.7 ± 0.1 Ma for volcanic rocks of the Bajo Pobre Formation and of 147.6 ± 1.1 Ma for the Chon Aike Formation. Illite ages of the Huevos Verdes vein system of 140.8 ± 0.2 and 140.5 ± 0.3 Ma are 4 m.y. younger than the volcanic host rock unit. These age dates are among the youngest reported for Jurassic volcanism in the Deseado massif and correlate well with the regional context of magmatic and hydrothermal activity. The Huevos Verdes vein system has a strike length of 2,000 m, with several ore shoots along strike. The vein consists of a pre-ore stage and three main ore stages. Early barren quartz and chalcedony are followed by a mottled quartz stage of coarse saccharoidal quartz with irregular streaks and discontinuous bands of sulfide-rich material. The banded quartz-sulfide stage consists of sulfide-rich bands alternating with bands of quartz and bands of chlorite ± illite. Late-stage sulfide-rich veinlets are associated with kaolinite gangue. Ore minerals are argentite and electrum, together with pyrite, sphalerite, galena, chalcopyrite, minor bornite, covellite, and ruby silver. Wall rock alteration is characterized by narrow (220°C. Kaolinite occurring with the late sulfide-rich veinlet stage indicates pH 315°, whereas strike directions of <315° are predicted with an induced dextral strike-slip movement. The components of the structural model appear to be present on a regional scale and are not restricted to the San José district.

    The 13th Gravitational Wave Data Analysis Workshop took place in San Juan, Puerto Rico on the 19-22 January 2009. This annual event has become the established venue for presenting and discussing new results and techniques in this crucial subfield of gravitational wave astronomy. A major attraction of the event is that scientists working with all possible instruments gather to discuss their projects and report on the status of their observations. The Center for Gravitational Wave Astronomy at the University of Texas at Brownsville, USA (a National Aeronautics and Space Administration University Research Center and a National Science Foundation Center for Research Excellence in Science and Technology) jointly with the National Astronomy and Ionosphere Center (which operates the Arecibo Observatory) were the proud sponsors of the gathering this time. As in previous years, GWDAW13 was well attended by more than 100 participants from over 10 countries worldwide As this issue is going to press GEO, LIGO and VIRGO are undergoing new scientific runs of their instruments with the LIGO detectors holding the promise of increasing their operational sensitivity twofold as compared with the observations finished a couple of years ago. This new cycle of observations is a major milestone compared to the previous observations which have been accomplished. Gravitational waves have not been observed yet, but the instrumental sensitivity achieved has started producing relevant astrophysical results. In particular, very recently (Nature, 20 August 2009) a letter from the LIGO Scientific Collaboration http://www.ligo.org and the VIRGO Collaboration http://www.virgo.infn.it has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where current gravitational wave detectors can observe. These results have put new constraints on the physical characteristics of the early universe. The proximity

    Diabetic dyslipidemia is common in type 2 diabetes. The TaqIB polymorphism in cholesteryl ester transfer protein (CETP; B1 and B2 alleles; rs708272) is associated with changes in enzyme activity and lipid concentrations. The aim of the present study was to assess associations of CETP genotypes with lipoprotein profile, oxidant/anti-oxidant status and the plasma activity of paraoxonase-1 (PON-1) in a population of diabetic patients living in San Luis, Argentina. For oxidative stress status parameters, thiobarbituric acid-reactive substances (TBARS) and nitric oxide (NO) levels, and catalase and PON-1 activity were assessed in 40 patients with type 2 diabetes mellitus and 30 healthy participants. CETP polymorphism was analyzed by polymerase chain reaction-based methods. Type 2 diabetes mellitus had significantly higher concentrations of oxidative stress parameters: TBARS (P diabetics (P = 0.0002 and P = 0.0008, respectively). The CETP genotypes distribution among study groups was not significantly different. The B2 carriers of the TaqIB CETP polymorphism are associated with higher high-density lipoprotein cholesterol levels and PON-1 activity in control and type 2 diabetes mellitus patients. Linear regression analysis showed that there was a significant and positive correlation between the changes of PON-1 activity and high-density lipoprotein cholesterol levels in non-B1B1 (B2 carriers) in controls (r = 0.83, P diabetic patients (r = 0.39, P = 0.0003). The results of the current study show that type 2 diabetes mellitus is characterized by intense oxidative stress, and that the alterations observed in the lipoprotein profile and PON-1 activity might be related to the higher CETP activity in diabetic patients as a consequence of insulin resistance.

    Full Text Available In situ records of sea surface temperature collected between 2005 and 2009 were used to compare, for the first time, the temperature estimated by the Multichannel algorithms (MCSST of the Advanced Very High Resolution Radiometer (AVHRR sensors in San Matías Gulf, in the north of the Argentinean Patagonian Continental Shelf (between 40°47'-42°13'S. Match-ups between in situ records and satellite sea surface temperature (SST were analyzed. In situ records came from fixed stations and oceanographic cruises, while satellite data came from different NOAA satellites. The fitting of temperature data to a Standard Major Axis (SMA type II regression model indicated that a high proportion of the total variance (0.53< r² <0.99 was explained by this model showing a high correlation between in situ data and satellite estimations. The mean differences between satellite and in situ data for the full data set were 1.64 ± 1.49°C. Looking separately into in situ data from different sources and day and night estimates from different NOAA satellites, the differences were between 0.30 ± 0.60°C and 2.60 ± 1.50°C. In this paper we discuss possible reasons for the above-mentioned performance of the MCSST algorithms in the study area.

    Volcanism at Sierra del Morro represents the final stages of the flat-slab related magmatism in the easternmost San Luis Neogene Volcanic Belt. This 80 km-long NW-WNW-trending belt tracks the episodic inland migration of both magmatism and tectonic deformation since 18 Ma. The Sierra del Morro stands out in the Eastern Sierras Pampeanas as a metamorphic block uplifted during the Late Miocene-Pleistocene by a combination of magma injection and tectonic deformation. Although sequences that preserve stages of basement updoming are not often preserved, exposures in Sierra del Morro are exception in providing key evidence and insight into the involved processes. Based on the comprehensive study of volcanic stratigraphy and structures, the reconstruction of the volcanic architecture has been carried out. We infer a three stage evolution of the El Morro caldera as follows: 1) pre-collapse updoming and volcanism, 2) collapse caldera formation and 3) post-caldera volcanism. The ascent of magma is recorded in small tumescence sites, strongly controlled by oblique transtensional WNW-NW and ENE-striking brittle-ductile megashear zones. Even though the area affected by tumescence was large, magma injection progressed only locally. At Cerros Guanaco and Pampa, metamorphic rocks were updomed and strongly brecciated, whereas at Sierra del Morro magma was emplaced as pre-collapse domes with associated block-and-ash flows, ignimbrite caldera-forming eruptions and post-caldera lava domes and dykes. The caldera is located in the intersection of two major oblique transtensional WNW-NW and ENE-trending brittle-ductile megashear zones, where the highest positive dilatation occurred.

    Full Text Available The objective of this study is to provide information about a harbour-fouling community dominated by Metridium senile in southern Patagonia. Several steel tubes from the wharf of Puerto San Julián were extracted to perform repair tasks, allowing the attached benthic community to be studied. Sampling was conducted at three levels: lower intertidal, 3-4 m depth and 6-7 m depth. In the lower intertidal, M. senile had a relative abundance of 43%, the most abundant accompanying species being Perumytilus purpuratus, Mytilus edulis platensis and Aulacomya atra atra. At subtidal level, the anemone showed relative abundances of 64% and 65%, and was accompanied by Monocorophium insidiosum at 3-4 m depth and by polychaetes of families Sabellidae and Syllidae at 6-7 m at depth. In the lower intertidal, epibiosis was more frequent on P. purpuratus, A. atra atra and M. edulis platensis, while in the subtidal, the richness of substrate-organisms increased significantly and the anemone was fixed to A. atra atra, M. edulis platensis, Paramolgula gregaria, Crepipatella dilatata, Austromegabalanus psittacus, Hiatella arctica, Polyzoa opuntia, Pyura sp. and Sabellidae tubes. The ability of M. senile to settle on many different organisms, along with other strategies, makes it a colonizer able to displace other species that could compete with it for substratum. Given the cosmopolitan nature of M. senile, the fact that this species has not been previously reported in the coastal zone of the region, and the results of our study, we discuss the possibility that this sea anemone is an invasive alien species in southern Patagonia, or at least a cryptogenic species.

Sin embargo, los factores climáticos, especialmente la temperatura, pueden ser considerados los más importantes en las regiones templadas. Se midió la actividad de forrajeo y el tamaño del nido en cuatro colonias de Acromyrmex lobicornis Emery en la localidad de Juana Koslay, San Luis. La actividad forrajera se determinó a partir del número de hormigas que ingresan al nido cargadas con fragmentos vegetales por unidad de tiempo, a lo largo de un año. Se midió la temperatura del aire y el suelo en cada oportunidad. Para estimar el tamaño del nido, se midió el área de forrajeo, el diámetro del túmulo y el número de obreras en cada colonia. Se encontraron asociaciones entre la actividad de forrajeo y las temperaturas del aire y del suelo en todos los meses del año, a excepción de febrero, julio y diciembre. Esta asociación fue positiva en los meses de octubre, mayo, junio, agosto y setiembre; pero negativa en los meses de noviembre, enero, marzo y abril.

    Science.gov (United States)

    Dengue is transmitted by Aedes aegypti, a species that thrives in cities. Here we ask which elements within the urban environment could be managed to reduce the potential for Dengue occurrence. In particular, we study the potential of wetlands in the SJBE to buffer from vector proliferation. Wetlands provide ecosystem services such as heat and water hazard mitigation, water purification and habitat for a diversity of species, all of which are factors that have been shown to affect Dengue vectors. As such, we hypothesize that within coastal neighborhoods in the SJBE wetlands, ecosystem services lead to lower Dengue occurrence. We test this hypothesis using Dengue data from 2010-2013, which includes the largest epidemic in PR history. Our analytical model includes relevant socio-economic factors and environmental controls that may also affect Dengue dynamics. Results indicated a negative effect of neighborhood mangrove cover and a positive effect of percent flood area on Dengue prevalence. Moreover, heat hazards were positively correlated with dengue prevalence and negatively correlated with neighborhood mangrove cover. Dengue prevalence did not correlate with herbaceous wetlands, or with the ecosystem services of water quality or vertebrate species richness. Mosquito borne diseases are an increasingly important health concern, which pose great challenges for safe and sustainable control and eradication. This reality calls for management approaches that consider m

    Because earthquakes on large active thrust or reverse faults are not always accompanied with surface rupture, paleoseismological estimation of their associated seismic hazard is a difficult task. To improve the seismic hazard assessments in the Andean foreland of western Argentina (San Juan Province), this paper proposes a novel approach that combines structural geology, geomorphology and exposure age dating. The Eastern Precordillera of San Juan is probably one of the most active zones of thrust tectonics in the world. We concentrated on one major regional active reverse structure, the 145 km long Villicúm-Pedernal thrust, where this methodology allows one to: (1) constrain the Quaternary stress regime by inversion of geologically determined slip vectors on minor or major fault planes; (2) analyse the geometry and the geomorphic characteristics of the Villicúm-Pedernal thrust; and (3) estimate uplift and shortening rates through determination of in situ-produced 10Be cosmic ray exposure (CRE) ages of abandoned and uplifted alluvial terraces. From a structural point of view, the Villicúm-Pedernal thrust can be subdivided into three thrust portions constituting major structural segments separated by oblique N40°E-trending fault branches. Along the three segments, inversion of fault slip data shows that the development of the Eastern Precordillera between 31°S and 32°S latitude is dominated by a pure compressive reverse faulting stress regime characterized by a N110°+/- 10°E-trending compressional stress axis (σ1). A geomorphic study realized along the 18 km long Las Tapias fault segment combined with CRE ages shows that the minimum shortening rate calculated over the previous ~20 kyr is at least of the order of 1 mm yr-1. An earthquake moment tensor sum has also been used to calculate a regional shortening rate caused by seismic deformation. This analysis of the focal solutions available for the last 23 yr shows that the seismic contribution may be three

    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.

    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

    Lee, K. (Principal Investigator); Huntley, D.

    1976-01-01

    The author has identified the following significant results. Ground water recharge to the aquifers of San Luis Valley west of San Luis Creek was primarily from ground water flow in the volcanic aquifers of the San Juan Mountains. The high permeability and anisotropic nature of the volcanic rocks resulted in very little contrast in flow conditions between the San Juan Mountains and San Luis Valley. Ground water recharge to aquifers of eastern San Luis Valley was primarily from stream seepage into the upper reaches of the alluvial fans at the base of the Sangre de Cristo Mountains. The use of photography and thermal infrared imagery resulted in a savings of time and increase in accuracy in regional hydrogeologic studies. Volcanic rocks exhibited the same spectral reflectance curve as sedimentary rocks, with only the absolute magnitude of reflectance varying. Both saline soils and vegetation were used to estimate general ground water depths.

Sin embargo, los factores climáticos, especialmente la temperatura, pueden ser considerados los más importantes en las regiones templadas. Se midió la actividad de forrajeo y el tamaño del nido en cuatro colonias de Acromyrmex lobicornis Emery en la localidad de Juana Koslay, San Luis. La actividad forrajera se determinó a partir del número de hormigas que ingresan al nido cargadas con fragmentos vegetales por unidad de tiempo, a lo largo de un año. Se midió la temperatura del aire y el suelo en cada oportunidad. Para estimar el tamaño del nido, se midió el área de forrajeo, el diámetro del túmulo y el número de obreras en cada colonia. Se encontraron asociaciones entre la actividad de forrajeo y las temperaturas del aire y del suelo en todos los meses del año, a excepción de febrero, julio y diciembre. Esta asociación fue positiva en los meses de octubre, mayo, junio, agosto y setiembre; pero negativa en los meses de noviembre, enero, marzo y abril. Las colonias mostraron actividad diurna en invierno y nocturna en verano. La temperatura y el tamaño del nido son factores que influyen sobre la actividad de forrajeo de A. lobicornis.Many factors can affect the foraging activity of leaf-cutting ants. However, climatic factors, especially temperature, could be considered the most important in temperate regions. In this work, we measured foraging activity and nest size in four colonies of Acromyrmex lobicornis Emery located in Juana Koslay, San Luis. Foraging activity was determined by the number of ants carrying plant fragments that entered the nest per unit time during a year. In each opportunity air and soil temperature were measured. To estimate nest size we used foraging area, mound diameter and number of workers in each colony Foraging activity and air and soil temperature correlated in every month of the year except February

Se capturaron 329 ejemplares de Triatoma infestans, 293 en 4 terrazas de torres de 7 pisos y 36 en el interior de la bodega, associados con numerosas palomas que colomizaban estos sitios. Los insectos se refugiaban en el guano acumulado entre bloques de cemento que cubren las terrazas y en la bodega dentro de toneles en desuso. Se identificaron dos focos principales de vectores associados con densos palomares: un 81,5% del total de triatomas colectados se halló en una de las torres y un 11% en la bodega. A los 6 meses del tratamiento insecticida, resultaron positivas terrazas en las que previamente no se habia capturado T. infestans. El perfil alimentario de los triatomas muestra un predominio de ingestas simples sobre ave; en los edificios y en la bodega el 95% de los T. infestans analizados se alimentó sólo de ave; el resto fueron ingestas simples o dobles sobre humano, perro o gato. Ningún T. infestans presentó infección con Trypanosoma cruzi.

    Full Text Available En este trabajo se evalúa la susceptibilidad a la ocurrencia de procesos de licuefacción de suelos asociados a sismos destructivos en el área ubicada al norte del río San Juan. Los terremotos de 1894, 1944, 1952 y 1977 provocaron licuefacción en el centro oeste de Argentina y particularmente en numerosos sitios de la provincia San Juan, resultando la zona norte del valle de Tulum, una de las más afectadas. Los registros históricos de procesos de licuefacción de suelos (PLS ocurridos durante los terremotos mencionados, evidencian grietas, volcanes de arena, cráteres y asentamientos diferenciales, los que ocasionaron importantes daños a las viviendas y al sector agro industrial de la región. En este estudio se efectuó un análisis de los factores principales que influyen en su ocurrencia, como también los efectos de la licuefacción. Se evaluaron y ponderaron los factores condicionantes tales como origen y granulometría del depósito, edad de los depósitos, profundidad del nivel freático y registros históricos entre otros. Del análisis de los factores resultó un mapa asociado a una tabla evaluativa. La influencia de los factores en la evaluación de la susceptibilidad se realizó mediante un proceso iterativo de superposición de mapas. Una vez conseguida la combinación óptima se obtuvo un mapa final de susceptibilidad a la licuefacción. La zonificación lograda se relacionó a un índice de susceptibilidad (IS, catalogado cualitativamente como Muy Alto, Alto, Moderado y Bajo. Los resultados obtenidos permiten concluir que el sector medio del abanico aluvial del río San Juan, donde se concentran los centros urbanos y la mayor actividad agropecuaria, es el sitio donde se exponen las condiciones de Muy Alta susceptibilidad, mientras que las de Alta susceptibilidad ocupan algunas zonas del sector medio-distal del abanico y las de Moderada a Baja se circunscriben al sector proximal del abanico.

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. Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available From the eighteenth century until today Cuyo and central Chile have been the main viticulture centers in Latin America and one of the most developed in the world. Their wine and spirits making have had important social, economic, politic and cultural implications in the region. Behind this, there has been viticulture, intensive and specialized farm-working, and viticulturists, who have had key roles. This article, based on originals and unpublished documents from Santiago, Mendoza, and San Juan notaries and court archives, examines varieties cultivated in the region. At the end, a document corpus was generated with 3.5 million plants in order to identify time of entry, adaptation, and propagation of grape varieties from Spanish colonization until French strains entered the region during mid nineteenth century. In particular, coexistence of Pais grape and Italia grape (muscat of Alexandria is examined, which had direct influence over the appearance of the Torrontes variety.

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

    This paper describes the progress in the bilateral cooperation project between academic and water resources management institutions from the Andes region of Argentina and Chile. The study zone is located in fragile ecosystems and mountain areas of the Andes (limit zone between the Province of San Juan, Argentina, and the IV Region of Coquimbo, Chile), with arid climate, where snow precipitates in the headwaters of watershed feed the rivers of the region by melting, which are the only source of water for human use, productive and energetic activities, as well as the native flora and fauna. CONAE, the Argentine Space Agency, participates in the Project through the provision of satellite data to the users and by this it contributes to ensuring the continuity of the results of the project. Also, it provides training in digital image processing. The project also includes the participation of water resource management institutions like Secretaria de Recursos Hidricos of Argentina and the Centro de Información de Recursos Naturales de Chile (CIREN), and of academic institution like the University of San Juan (Argentina) and University of La Serena (Chile). These institutions benefit from the incorporation of new methodologies advanced digital image processing and training of staff (researcher, lecturers, PhD Students and technical). Objectives: 1-Improve water distribution incorporating space technology for application in the prediction models of the stream flow. 2- Conduct an inventory of glaciers as well as studies in selected watersheds in the Andean region, aiming to know the water resource, its availability and potential risks to communities in the region. 3. Contribute to vulnerability studies in biodiversity Andean watersheds. Results: For estimation Snow cover Area, the MODIS images are appropriate due their high temporal resolution and allows for monitoring large areas (greater than 10 km) The proposed methodology (Use of snow index, NSDI) is appropriate for

    Full Text Available The Juan Fernández and Desventuradas islands are among the few oceanic islands belonging to Chile. They possess a unique mix of tropical, subtropical, and temperate marine species, and although close to continental South America, elements of the biota have greater affinities with the central and south Pacific owing to the Humboldt Current, which creates a strong biogeographic barrier between these islands and the continent. The Juan Fernández Archipelago has ~700 people, with the major industry being the fishery for the endemic lobster, Jasus frontalis. The Desventuradas Islands are uninhabited except for a small Chilean military garrison on San Félix Island. We compared the marine biodiversity of these islands across multiple taxonomic groups. At San Ambrosio Island (SA, in Desventuradas, the laminarian kelp (Eisenia cokeri, which is limited to Desventuradas in Chile, accounted for >50% of the benthic cover at wave exposed areas, while more sheltered sites were dominated by sea urchin barrens. The benthos at Robinson Crusoe Island (RC, in the Juan Fernández Archipelago, comprised a diverse mix of macroalgae and invertebrates, a number of which are endemic to the region. The biomass of commercially targeted fishes was >2 times higher in remote sites around RC compared to sheltered locations closest to port, and overall biomass was 35% higher around SA compared to RC, likely reflecting fishing effects around RC. The number of endemic fish species was extremely high at both islands, with 87.5% of the species surveyed at RC and 72% at SA consisting of regional endemics. Remarkably, endemics accounted for 99% of the numerical abundance of fishes surveyed at RC and 96% at SA, which is the highest assemblage-level endemism known for any individual marine ecosystem on earth. Our results highlight the uniqueness and global significance of these biodiversity hotspots exposed to very different fishing pressures.

    San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to

    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.

A interação ser humano-animal é fundamental para o entendimento de temas filosóficos presentes no romance, como a identidade humana, o outro, a morte. O corvo é o batedor da chegada de Juan Preciado no mundo da morte. O cavalo de Miguel Páramo é o único ser que sofre, verdadeiramente, a morte do seu tutor. O gato é o animal que faz visitas noturnas a Susana San Juan, com quem estabelece um diálogo somente inteligível para os dois. A integração entre personagens humanas e animais em Pedro Páramo mostra a comunicação entre seres pertencentes a diferentes espécies animais. No romance, seres humanos, corvos, cavalos e gatos têm mais semelhanças entre si do que a cultura ocidental antropocêntrica conhece.In Pedro Páramo by Juan Rulfo, the raven, the horse and the cat are animals that maintain a close existential link to the human beings. In the book, this human being/animal interaction is fundamental to the understanding of philosophical themes such as the identity, the other, and the death. In the story, the raven is the escort of Juan Preciado arrival into the death world. Miguel Páramos’s horse is the only being that genuinely suffers because of the death of its guardian, that is, Miguel’s death. The cat is the animal that make night visits to Susana San Juan to whom it speaks in a way that is understood by the two of them only. The connection between human and animal characters in Pedro Páramo shows the communication among beings that belong to different animal species. In the novel, human beings, ravens, horses, and cats are much more alike than the western anthropocentric culture has it.
