    Full Text Available Para definir la distribución geográfica del ocelote en el estado de San Luis Potosí, México, se obtuvieron nuevos registros de la especie. El estudio se realizó de enero de 2007 a abril de 2009. Se obtuvieron 41 registros de ocelotes por medio de entrevistas y trampeo-fotográfico. Los registros se localizaron en comunidades vegetales de selva baja caducifolia (37%, matorral submontano (22%, bosque de encino (15%, selva mediana (10%, selva alta perennifolia, bosque mesófilo de montaña, bosque de pino-encino y matorral desértico micrófilo (10%. La presencia de ocelotes se ubicó en los municipios de Ciudad del Maíz, El Naranjo, Cerritos, Guadalcázar, San Nicolás Tolentino y Ciudad Valles en de elevaciones de 38 a 2 400 m snm. Los resultados de esta investigación sugieren una distribución del ocelote más hacia el oeste del estado respecto a su distribución original. El presente estudio definió nuevas regiones con presencia de ocelotes que pueden ser consideradas en el desarrollo de estrategias de conservación de la especie en el estado de San Luis Potosí.To determine the geographic distribution of ocelot in the state of San Luis Potosí, Mexico, we obtained new records. The study was conducted from January 2007 to April 2009. We recorded 41 ocelot records by interviews and camera-trapping. Ocelots records were located in tropical deciduous forest (37%, semitropical thornscrub (22%, oak forest (15%, tropical forest (10%, tall tropical deciduous forest, desert scrub, pine-oak forest and clouded forest (10%. Ocelot records were located in the municipalities of Ciudad del Maíz, El Naranjo, Cerritos, Guadalcazar, San Nicolás Tolentino and Ciudad Valles where the elevation ranged from 38 to 2 400 m. The evidence of this research suggests that ocelot range is more extended to the west than its original geographical range.

  2. Magmatism and mineralization ages from northeast area of La Sierra de San Luis, Argentina

    International Nuclear Information System (INIS)

    Three igneous rock groups, characterized as pre, sin and post-kinematics, have intruded the crystalline basement of Sierra de San Luis, Argentina. The ore deposits are associated with Devonian to Carboniferous epizonal granite stocks and batholiths in an area underlain by metamorphic rocks. This granitoids are characterized as post-kinematics magmatism. Model lead ages on the ore deposits (338,8 - 292,1 Ma) are strongly supported by K-Ar ages of the intrusives. The bulk of the north Sierra de San Luis ore deposits are genetically related to late Carboniferous granite plutons. The ore bodies are tungsten veins with greisen envelopes, lead veins, epithermal fluorite veins and REE and Th deposit. A generalized scheme of ore bodies related to granites is proposed. The ore deposits and their lithotectonic setting are characteristic of Gondwana metallogenetic Epoch in the Sierra de San Luis (au)

    Thompson, Ren A.; Machette, Michael N.

    1989-01-01

    This report is a digital image of the U.S. Geological Survey Miscellaneous Investigations Series Map I-1906, 'Geologic map of the San Luis Hills area, Conejos and Costilla Counties, Colorado,' which was published in 1989 by Thompson and Machette, scale 1:50,000 but has been unavailable in a digital version. The map area represents the southwestern portion of the Alamosa 30' x 60' quadrangle, which is currently being remapped by the U.S. Geological Survey. The northern and eastern margins of the San Luis Hills area have been remapped at greater detail and thus small portions of the map area have been updated. The northern margin is shown on U.S. Geological Survey Open-File Report 2005-1392, the northeastern portion is shown on U.S. Geological Survey Open-File Report 2008-1124, and the eastern margin is shown on U.S. Geological Survey Open-File Report 2007-1074. The most significant changes to the 1989 map area are recognition of Lake Alamosa and its deposits (Alamosa Formation), remapping of bedrock in the northeastern San Luis Hills, and redating of volcanic units in the San Luis Hills. Although unpublished, new 40Ar/39Ar ages for volcanic units in the Conejos and Hinsdale Formations add precision to the previous K/Ar-dated rocks, but do not change the basic chronology of the units. The digital version of this map was prepared by Theodore R. Brandt by scanning the original map at 300 pixels per inch, prior to creating the press-quality (96 Mb) and standard (5 Mb) .pdf files.

  15. Provenance and tectonic setting of the protoliths of the Metamorphic Complexes of Sierra de San Luis

    Directory of Open Access Journals (Sweden)

    MG López de Luchi

    2003-12-01

    Full Text Available A major and trace element based characterization of the metasedimentary protoliths of three metamorphic units of Sierra de San Luis (Pringles Metamorphic Complex, San Luis Formation and Conlara Metamorphic Complex is presented. Geochemistry indicates a dominance of shales in the protoliths of San Luis Formation, whereas greywackes and shales made up the Conlara Metamorphic complex and mainly greywackes, the Pringles Metamorphic Complex. Both major element data and trace element ratios (i.e. Th/Sc, Th/U, indicate a source with an average upper crustal composition for the protoliths of the Pringles Metamorphic Complex, the San Luis Formation and the shales of the Conlara Metamorphic complex. A component with less evolved signature may be inferred for the metagreywackes of the Conlara metamorphic Complex. Mixed sourced detritus are indicated for the three units with clastic material resulting mainly from both andesitic and acidic/recycled detritus. The overall data consistently suggest a continental island arc and/or active margin setting as the more probable geodynamic scenario for the deposition of the sedimentary precursors of the studied units. In this context, a back-arc setting can account for the mixed nature of the inferred source areas with uplifted old basement and arc-related detritus as the end members of the mixtures. The inferred back-arc basin would have evolved through the Cambrian receiving the sediments derived from the Pampean Orogen to the east combined with probably some old crust exposures and to the west the source might have been controlled by the active continental margin.

    2007-09-01

    Full Text Available El plutón La Florida se localiza en la parte central de la Sierra de San Luis y se aloja en metasedimentitas regionales de grado medio pertenecientes al grupo micaesquistos derivadas de subgrauvacas y areniscas. Es de morfología semicircular, ligeramente elongado en dirección oblicua a la foliación regional, la cual acompaña la forma del plutón en el contacto. Su composición es monzogranítica y marcadamente peraluminoso, y está compuesto por cuarzo, microclino, plagioclasa, muscovita, biotita y granate. El estudio detallado ha permitido establecer que el contenido de biotita de los monzogranitos disminuye hacia los bordes del cuerpo en tanto que la muscovita, generalmente porfiroblástica, aumenta, lo cual conduce a variaciones notables del índice de color de las rocas. Además, se registra una abundante pegmatización que forma tanto diques como cuerpos irregulares en el borde del intrusivo y también en las rocas de caja adyacentes al contacto. Esta zonación sería resultado del incremento de fluidos acuosos durante la etapa tardío magmática, que causaron reacciones subsólidas en la mineralogía ortomagmática. El magma está relacionado con el proceso subductivo desarrollado durante la orogenia famatiniana, muestra afinidad con fundidos sin-colisionales y un tren evolutivo compatible con magmas de tipo S. El plutón de La Florida exhibe algunas diferencias geológicas, petrográficas y composionales con otros granitoides sin-cinemáticos de la sierra de San Luis, encontrándose algunas similitudes solamente con rocas del cordón de El Realito.La Florida pluton is located in the central part of the Sierra de San Luis. It is a nearly semicircular-shape intrusion, slightly elongated perpendicularly to the main NNE-SSW country rocks foliation, which deforms at the pluton margins.

Leon reservoir one core from the entrance and another one close to the wall were investigated. 232Th-series, 238U-series, 40K and 137Cs activity concentrations (AC, Bq kg−1) were determined by gamma spectrometry with a high purity Ge detector. 238U and 234U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to 210Pb activities. Results were verified by 137Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High 238U-series AC values were found in sediments from San Marcos reservoir, because this site is located close to the Victorino uranium deposit. Low AC values found in Luis L. Leon reservoir suggest that the uranium present in the source of the Sacramento – Chuviscar Rivers is not transported up to the Conchos River. Activity ratios (AR) 234U/238U and 238U/226Ra in sediments have values between 0.9–1.2, showing a behavior close to radioactive equilibrium in the entire basin. 232Th/238U, 228Ra/226Ra ARs are witnesses of the different geological origin of sediments from San Marcos and Luis L. Leon reservoirs

At San Marcos reservoir one core was studied, while from Luis L. Leon reservoir one core from the entrance and another one close to the wall were investigated. ²³²Th-series, ²³⁸U-series, ⁴⁰K and ¹³⁷Cs activity concentrations (AC, Bq kg⁻¹) were determined by gamma spectrometry with a high purity Ge detector. ²³⁸U and ²³⁴U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to ²¹⁰Pb activities. Results were verified by ¹³⁷Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High ²³⁸U-series AC values were found in sediments from San Marcos reservoir, because this site is located close to the Victorino uranium deposit. Low AC values found in Luis L.

Contenidos de Si, K, Ba y tierras raras livianas superiores a los promedios de lamprófiros calcoalcalinos, serían producidos por un mayor grado de contaminación cortical. La edad K-Ar en fenocristales de flogopita es 408 ± 6 Ma por lo que el lamprófiro estaría relacionado a las etapas finales del magmatismo famatiniano de las Sierras Pampeanas.The lamprophyre from El Puesto, sierra de San Luis, is a minette, calc-alkaline rock-type. It is a dyke that intrudes metamorphic rocks from Complejo Metamórfico Las Aguadas and igneous rocks from Rodeo Viejo tonalitic pluton. Its texture is porphyritic with phlogopite and apatite, and minor proportions of amphibole and rutile. K-feldspar, apatite, rutile, hematite, carbonates, sphene, quartz and altered clinopyroxene form the groundmass. High SiO2, K2O, ligth rare earths, Ba, Sr, Zr y Hf contents are the geochemical characteristics, and negative Nb anomaly is present. Enrichment in Si, K, Ba and ligth rare earths contents, higher than calc-alkaline lamprophyres, could be caused by a major degree of crustal contamination. A K-Ar age on phlogopite phenocrysts yield 408 ± 6 Ma, relating the lamprophyre intrusion with the latest famatinian magmatism cycle of Sierras Pampeanas.

    Full Text Available Nesting ecology of Morelet's crocodile (Crocodylus moreletii has been documented since 1940. However, only 2 nests constructed on floating vegetation have been recorded. Here, we presented additional information from a mainland population of C. moreletii in the Ciénega de Cabezas wetland, San Luis Potosí, describing 2 nests constructed on floating mats of cattails. The nests were constructed using Typha sp., close to the main channel. One nest was lost due to flooding, and contained 32 eggs. Seven eggs had a mean 72.6 ± 2.63 mm length (range = 70.0 -75.0 mm, 45.0 ± 2.30 mm width (range = 41.0-48.0 mm, and 140.7 ± 2.98 mm diameter (range = 136.0-145.0 mm. We suggest that the use of floating vegetation for nesting by C. moreletii is related to the availability of aquatic vegetation, combined with the lack of adequate nesting sites on land.La ecología de anidación del cocodrilo de pantano (Crocodylus moreletii ha sido documentada desde 1940.

The basament is constituted by high grade metamorphic rocks with few associated metabasites. Earth gravity and magnetic field measurements are indicative of the presence of bigger volumes of mafic rocks below the surface, which carry anomalous concentrations of ferromagnetic and/or paramagnetic minerals (magnetite and/or sulfides. An excess of mass below this Sierra is shown by Bouguer gravimetric anomalies with magnitudes similar to those measured in the Sierra Grande de San Luis. Positive magnetic anomalies are indicative of the presence of mafic rocks with anomalous concentrations of magnetic minerals.

  4. Mineralogy of auriferous deposits of the quaternary deposits in the San Luis Province, Argentina

    International Nuclear Information System (INIS)

    The objective of this work is to study the mineralogy of the sands and clays of the quaternary deposits in the San Luis Mountain, Argentina. A series of algorithms applied to the sand fraction has permitted to determine sedimentary discontinuities. The two micron fraction of the sediments has been studied by a quantification technique based on X-ray diffraction by means of oriented preparations and run with copper tube. These quaternary silts have received fluvial lateral contributions. The high cristalinidad of non expandibles and fireclay clay show the antique of the silts. The polygenic processes have generated a great variety of clay mineral species like a large quantities of illite and in lesser extend kaolinite and smectites. The illite was probably generated by diagenetic changes. The high cristalinidad of non expandibles and fireclay clay show the antique of the silts

    International Nuclear Information System (INIS)

    In the south of the Sierra de San Luis is recognized a basement composed by La Escalerilla and Los Puquios granites, accompanied by schist, mylonite s and mafic-ultramafic rocks. The schists, La Escalerilla granite and the mafic -ultramafic rocks are affected by a regional metamorphism in anphibolites facies, the two first present a N-S foliation di ping to east. The mylonite s correspond to a second event of deformation, distributed in thin belts of NNE-SSO direction and inclination to east, developed in green schist to anphibolites facies. Los Puquios granite represents the more young of the basement rocks and the intrusion was associated with a shear zone. Los Puquios granite forms dikes and small plutons cutting La Escalerilla granite and micas chits in high cortical levels

    Essential oils obtained from eight aromatic plants of San Luis Province, Argentina, were screened for virucidal activity against herpes simplex virus type 1 (HSV-1), Junin virus (JUNV) and dengue virus type 2 (DEN-2). The most potent inhibition was observed with the essential oil of Lippia junelliana and Lippia turbinata against JUNV with virucidal concentration 50% (VC(50)) values in the range 14-20 ppm, whereas Aloysia gratissima, Heterotheca latifolia and Tessaria absinthioides inhibited JUNV in the range 52-90 ppm. The virucidal activity was time- and temperature-dependent. The essential oils of A. gratissima, Artemisia douglasiana, Eupatorium patens and T. absinthioides inactivated HSV-1 at 65-125 ppm. However, only A. douglasiana and E. patens had any discernible effect on DEN-2 infectivity with VC(50) values of 60 and 150 ppm, respectively. PMID:14595590

    In the context of the economic crisis in the 1980s that affected Mexico and the rest of Latin America, official policies encouraged commercial agriculture, especially the cultivation of export crops. During that period, women's entry into the paid labor market accelerated. For many women in rural areas, this meant widening opportunities for participation and a chance not only to help their families, but also to look for a partner, earn their own money, and "see the world." This article analyzes the incorporation of women into the tomato agro-industry in the Altiplano region of el Valle de Arista, San Luis Potosí, Mexico. It discusses the strategies that women workers use-physical appearance, experience, and efficiency-as characteristics that are "required" in order to stay in this highly competitive, segmented, and precarious labor market.

    Lawrence Berkeley National Laboratory (LBNL), in collaboration with the US Bureau of Reclamation and the Panoche Water District, is conducting a pilot-scale test of the viability of land application of selenium (Se)-enriched San Luis Drain (SLD) sediments. Local land disposal is an attractive option due to its low cost and the proximity of large areas of available land. Two modes of disposal are being tested: (1) the application to a nearby SLD embankment, and (2) the application to and incorporation with nearby farm soils. The study of these options considers the key problems which may potentially arise from this approach. These include disturbance of SLD sediments during dredging, resulting in increased downstream Se concentrations; movement of the land-applied Se to the groundwater; increased exposure to the biota; and reduced productivity of farm crops. This report describes field and laboratory activities carried out from 1998 through November 2000, as well as the results of these investigations.

Rowlandius arduus sp. n. may be characterized by having movable finger of chelicerae with a diminute sub-distal tooth, male with a poorly developed dorsal eminence on abdominal segment XII, and female with two pairs of weakly sclerotized, sinuous spermathecal lobes, without conspicuous terminal lobe. It is assigned to Rowlandius tentatively, because some characters are not congruent with this genus, nevertheless the absence of synapomorphic characters limits its inclusion in other one.

    In June 1986 the Comision Federal de Electricidad (CFE) made tests to raise the load of the first normalized unit of 350 MW of the San Luis Potosi Power Plant; although the new system for colloidal silica removal had not yet been installed, consisting of a hollow fibers ultra-filtration system with a capacity of 110 m{sup 3}, that for the first time would be applied in a Mexican power plant. It was decided to install this system due to the fact that the well water supplying this power plant comes from a geothermal reservoir, with water at 38 degrees Celsius and a silica content of 15 to 250 parts per billion (ppb) of colloidal silica, which makes it necessary to eliminate it in order to enable the boiler operation at its design conditions (175 bars (2573 psig) and 540 degrees Celsius). Although a demineralizing plant existed for the boiler feed water make up, the ion exchange resins were not able to retain the colloidal silica. Also, the First Unit operation was held at 25% of its rated capacity; in trying to raise the output to 50%, the silica concentration in the boiler water went over the allowed limits, resulting in a concentration of 1,500 ppb in the boiler water and 28 ppb in the steam. One the ultra-filtration plant was installed, the power plant operated at full rated capacity with silica concentrations in the steam lower than the permitted concentration, i.e. 10 ppb . By the end of 1987 the Second Unit of 350 MW was put into operation with the ultra-filtration system in operation, reaching full load without any problem. Once confirmed the efficiency of the ultra-filtration for the colloidal silica removal, CFE will apply this system in other power plants of the country having the same problem.

    Full Text Available Gardens have become increasingly important places for growing nutritional food, for conserving biodiversity, for biological and ecological research and education, and for community gathering. Gardens can also be designed with the goal of attracting specific wildlife, like birds and butterflies, but pollinators, like bees, can also be drawn to specially planned and modified gardens. A community garden in San Luis Obispo, California provided the setting for modification with the goal of attracting native bee pollinators by planting known bee-attractive plants. The local gardeners participated in a survey questionnaire and focused interviews to provide their input and interest in such a project. Presentations on our work with native bees in urban environments and gardening to attract bees were also given to interested gardeners. Work of this type also benefited from a lead gardener who managed donated bee plants and kept up momentum of the project. Modification of the garden and monitoring of native bees started in 2007 and continued through the growing season of 2009. Diversity of collected and observed native bees has increased each year since 2007. To date, 40 species in 17 genera of mostly native bees has been recorded from the garden, and this number is expected to increase through time.

  16. Tracing groundwater recharge in the San Luis Valley, Colorado: Groundwater contamination susceptibility in an agricultural watershed

    Science.gov (United States)

    Patel, Tanya; Hindshaw, Ruth; Singer, Michael

    2015-04-01

    Water is a vital resource in any agricultural watershed, yet in the arid western United States farming practices threaten the quality and availability of groundwater. This is a pressing concern in the San Luis Valley, southern Colorado, where agriculture comprises 30% of the local economy, and employs over half the valley population. Although 54 % of the water used for irrigation is surface water, farmers do not usually apply this water directly to their fields. Instead, the water is often diverted into pits which recharge the aquifer, and the water is subsequently pumped during the following irrigation season. The Rio Grande Water Conservation District recognises that recharge to the unconfined aquifer has been outpaced by commercial irrigation for at least four decades, resulting in a decline in groundwater levels. Recycled irrigation water, and leakage from unlined canals now represent the greatest recharge contribution to the unconfined aquifer in this region. This makes the shallow groundwater particularly susceptible to agricultural contamination. The purpose of this study is to assess groundwater contamination in the unconfined and upper confined aquifers of the San Luis Valley, which are the most susceptible to contamination due to their close proximity to the surface. Although concentrations of potentially harmful contaminants from agricultural runoff are regularly monitored, the large spatial and temporal fluctuations in values make it difficult to determine long-term trends. We have analysed δ18O, δ2H and major-ion chemistry of 57 groundwater, stream and precipitation samples, collected in June 2014, and interpreted them alongside regional stream flow data and groundwater levels. This will allow us to study the seasonality and locality of groundwater recharge to provide greater insight into the watershed's potential for pollution. A groundwater vulnerability assessment was performed using the model DRASTIC (Depth to water, Recharge, Aquifer media, Soil

    The main purpose of this study was to assess environmental contamination by arsenic and cadmium in a smelter community (San Luis Potosi City, Mexico) and its possible contribution to an increased body burden of these elements in children. Arsenic and cadmium were found in the environment (air, soil, and household dust, and tap water) as well as in the urine and hair from children. The study was undertaken in three zones: Morales, an urban area close to the smelter complex; Graciano, an urban area 7 km away from the complex; and Mexquitic, a small rural town 25 km away. The environmental study showed that Morales is the most contaminated of the zones studied. The range of arsenic levels in soil (117-1396 ppm), dust (515-2625 ppm), and air (0.13-1.45 micrograms/m3) in the exposed area (Morales) was higher than those in the control areas. Cadmium concentrations were also higher in Morales. Estimates of the arsenic ingestion rate in Morales (1.0-19.8 micrograms/kg/day) were equal to or higher than the reference dose of 1 microgram/kg/day calculated by the Environmental Protection Agency. The range of arsenic levels in urine (69-594 micrograms/g creatinine) and hair (1.4-57.3 micrograms/g) and that of cadmium in hair (0.25-3.5 micrograms/g) indicated that environmental exposure has resulted in an increased body burden of these elements in children, suggesting that children living in Morales are at high risk of suffering adverse health effects if exposure continues.

    This paper presents the data sources and methodology used to estimate Green Net Regional Product (GNRP), a green accounting approach, for the San Luis Basin (SLB). We measured the movement away from sustainability by examining the change in GNRP over time. Any attempt at green accounting requires both economic and natural capital data. However, limited data for the Basin requires a number of simplifying assumptions and requires transforming economic data at the national, state, and county levels to the level of the SLB. Given the contribution of agribusiness to the SLB, we included the depletion of both groundwater and soil as components in the depreciation of natural capital. We also captured the effect of the consumption of energy on climate change for future generations through carbon dioxide (CO(2)) emissions. In order to estimate the depreciation of natural capital, the shadow price of water for agriculture, the economic damages from soil erosion due to wind, and the social cost of carbon emissions were obtained from the literature and applied to the SLB using benefit transfer. We used Colorado's total factor productivity for agriculture to estimate the value of time (i.e., to include the effects of exogenous technological progress). We aggregated the economic data and the depreciation of natural capital for the SLB from 1980 to 2005. The results suggest that GNRP had a slight upward trend through most of this time period, despite temporary negative trends, the longest of which occurred during the period 1985-86 to 1987-88. However, given the upward trend in GNRP and the possibility of business cycles causing the temporary declines, there is no definitive evidence of moving away from sustainability. PMID:22483369

    Full Text Available En el presente trabajo se analizan las estructuras post-magmáticas del Granito La Escalerilla y se propone una interpretación sobre los mecanismos regionales de esfuerzos correspondientes al ciclo famatiniano en el sector suroccidental de la sierra de San Luis. Se considera que el plutón La Escalerilla condicionó el estilo de deformación de las unidades litológicas en su periferia. Ésta deformación estuvo ligada al contraste reológico producido entre el intrusivo y las metamorfitas de la roca de caja. La estructura del plutón está caracterizada por la presencia de: a una foliación interna de orientación meridiana particularmente marcada en los sectores de borde, así como al norte y sur del cuerpo, b una faja milonítica de rumbo NNE, en el contacto oriental, c cizallas dúctiles conjugadas de tipo Riedel (NNO y anti-Riedel (NE, estructuras interpretadas como parte de una tectónica de escape bajo un régimen transpresivo sinestral, y d fracturas tensionales de orientación ONO. Todas estas estructuras se considera que responden a esfuerzos compresivos de dirección ONO, que generan una componente real de esfuerzo tangencial sinestral,de módulo variable, como consecuencia de la oblicuidad general del plutón, respecto al eje de máximo esfuerzo (σ1. Sin embargo en algunos sectores esta componente tangencial es mínima debido a las diferentes orientaciones de los límites del cuerpo respecto al vector de máximo esfuerzo (σ1.

    The project report describes a two year experiment to control wetland drainage to the San Joaquin River of California from the San Luis National Wildlife Refuge using a decision support system for real-time water quality management. This system required the installation and operation of one inlet and three drainage flow and water quality monitoring stations which allowed a simple mass balance model to be developed of the seasonally managed wetlands in the study area. Remote sensing methods were developed to document long-term trends in wetland moist soil vegetation and soil salinity in response to management options such as delaying the initiation of seasonal wetland drainage. These environmental management tools provide wetland managers with some of the tools necessary to improve salinity conditions in the San Joaquin River and improve compliance with State mandated salinity objectives without inflicting long-term harm on the wild fowl habitat resource.

  3. Fossil content and structural relationships of the San Luis zone and the Caborca zone of NW Sonora, Mexico, suppression of the precambrian Z of Caborca

    International Nuclear Information System (INIS)

    In the Caborca region of western Sonora a Precambrian Z does not cover a unique Precambrian socle as previously believed. Two tectonic zones occur there instead: the San Luis Zone and the Caborca Zone. The first is comprised of the Precambrian San Luis socle of gneiss and granite, crossed by 1.1 Ga old anorthosites, the San Luis sedimentary cover, and, above it, a Lower Jurassic volcano-sedimentary sequence. The Caborca Zone consists of the Precambrian Bamori socle of parametamorphic rocks crossed by 1.1 Ga old Aibo granite, and of the Gamuza sedimentary cover. 1.1 Ga ago the two zones were far away from each other. They have been brought together by the Nevadian orogeny. Both zones are allochthonous, and the Caborca Zone is a nappe upon the San Luis Zone. The lowermost units of the Gamuza cover furnished psammocorals and a possible Pterophyllum jageri (?). Accordingly, its geological age is either Palaeozoic or Triassic.The San Luis cover furnished Nematophites [Prototaxites (?) and Nematothallus] from its lower part; Calcispongiae, Cardaicarpus' seeds, and Artisia from its upper part Thus, it is a Devono-Carboniferous unit. The study area belongs in the Baja-Borderland block, which underwent, an Eocene northwards drifting of about 900 - 1000 km, and a 30 celsius degrade to 40 celsius degrade clockwise rotation relative to the main part of Sonora.

An episodic lead loss for Cretaceous times (112 ± 23 Ma is postulated, based on the lower intercept of the discordia line. This age could be associated with anomalous thermal gradients due the extensional and rifting processes which affected Gondwana during the opening of the South Atlantic Ocean.

  8. An energy systems view of sustainability: emergy evaluation of the San Luis Basin, Colorado.

    Campbell, Daniel E; Garmestani, Ahjond S

    2012-03-01

    Energy Systems Theory (EST) provides a framework for understanding and interpreting sustainability. EST implies that "what is sustainable" for a system at any given level of organization is determined by the cycles of change originating in the next larger system and within the system of concern. The pulsing paradigm explains the ubiquitous cycles of change that apparently govern ecosystems, rather than succession to a steady state that is then sustainable. Therefore, to make robust decisions among environmental policies and alternatives, decision-makers need to know where their system resides in the cycles of change that govern it. This theory was examined by performing an emergy evaluation of the sustainability of a regional system, the San Luis Basin (SLB), CO. By 1980, the SLB contained a climax stage agricultural system with well-developed crop and livestock production along with food and animal waste processing. The SLB is also a hinterland in that it exports raw materials and primary products (exploitation stage) to more developed areas. Emergy indices calculated for the SLB from 1995 to 2005 revealed changes in the relative sustainability of the system over this time. The sustainability of the region as indicated by the renewable emergy used as a percent of total use declined 4%, whereas, the renewable carrying capacity declined 6% over this time. The Emergy Sustainability Index (ESI) showed the largest decline (27%) in the sustainability of the region. The total emergy used by the SLB, a measure of system well-being, was fairly stable (CV = 0.05). In 1997, using renewable emergy alone, the SLB could support 50.7% of its population at the current standard of living, while under similar conditions the U.S. could support only 4.8% of its population. In contrast to other indices of sustainability, a new index, the Emergy Sustainable Use Index (ESUI), which considers the benefits gained by the larger system compared to the potential for local environmental

    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

  12. Preliminary studies of stable isotope data in the Pancanta-La Carolina tungsten district, San Luis, Argentina

    International Nuclear Information System (INIS)

    In the southern part of igneous-metamorphic basement of Sierras de San Luis (Eastern Pampean Ranges) in the Pancanta area, are located the tungsten deposits; the distribution of W-bearing quartz vein mineralization was controlled by shear zones heterogeneously spride within the La Escalerilla Granite (early Devonian), Las Verbenas Tonalite (early Famatinian) and metasedimentary rocks (San Luis Formation). In the granite the W-bearing quartz vein mineralization are in contact with thin sheared tonalite bands. The close spacial relation between the granite and the W-deposits seem to indicate the influence of the granite hydrotemal activity in the ore-fluids. The calculated δ18O values of 6.0 per mil and 9.4 per mil from biotite and quartz, respectively (El Porvenir mine) resemble those for fluids in felsic magmas. The calculated δD values of -88 per mil from biotite (El Porvenir mine) lie below the fields for waters in felsic magmas. For other hand both calculated δ18O and δD values from biotite (El Porvenir mine) lie within the field late potassic alteration. The calculated δ 34S value = 6.0 per mil from pyrite in the Pancanta mine), will closely reflect those of the hydrothermal fluids at the temperatures of interest, with a significant input of metasedimentary sourced sulfur in the ore fluids (au)

A través de la aplicación del filtro de continuación ascendente a los datos del campo magnético total reducido al polo, se ha podido observar la configuración profunda de las distintas unidades. Entre ellas se destaca la secuencia supracortical, en parte correspondiente a la Formación San Luis, que permite reconstruir en varios sectores de la región, en algunos casos subaflorante, una importante sucesión de rocas metasedimentarias de hasta 3 km de espesor, que es interpretada como perteneciente a depósitos de una cuenca de antepaís formada con posterioridad a la orogenia pampeana, alrededor de los 530 Ma. Se caracterizan las distintas unidades metamórficas e ígneas a partir de su señal magnética, y sobre esta base se presenta una sección estructural profunda, que sirve de base para proponer la evolución tectónica del basamento de este sector de las Sierras Pampeanas.

    Full Text Available Hairdressing salons offer a wide range of services including treatments for hair and skin. However, these activities result in the production of residues that are improperly discharged into drainage, generating a negative impact on the environment. This study provides results of a first stage in a project regarding the analysis of waste disposal in hairdressing salons in the municipality of Ciudad Valles, San Luis Potosi, Mexico. Information gathering was conducted through a field work study by surveys given to workers in hairdressing salons in Ciudad Valles. The information presented in this study indicates that in hairdressing salons in Ciudad Valles there is no management plan for the management of waste that could be severely impacting the environment. The information presented here will be the basis for identifying priority areas for intervention, developing new research projects and setting new environmental policies. In addition, the results presented here can be extrapolated to many rural and urban areas all over Mexico.

Las anomalías negativas están representadas por un mínimo gravimétrico, estrecho y de gran desarrollo longitudinal que se define como cuenca de Nueva Galia y otro de forma subcircular, considerado una extensión de la subcuenca de Alvear. Se supone que ellas tuvieron su mayor desarrollo durante el lapso permo-triásico. Estas cuencas continúan su desarrollo hacia el norte y oeste, ligándose por un lado con la de Mercedes y por el otro con la de Alvear. En dirección sur se conectan con la cuenca de Quehué en la provincia de La Pampa.Geophysical determinations together with geological interpretations in the southern area of San Luis province indicate the existence of a strip of rocks with Pampean ages between Arizona and Justo Daract. The high-gravity anomalies are related to a belt of mafic rocks also recognized at Valle Daza (La Pampa. Low-gravimetric anomalies are consequence of basement rocks, such as those found at the Green quarry and at sedimentary basins. Volcanic rocks equivalent to the Choiyoi Group produce the positives between the basins and are also part of the basin basement. The basins are represented by an elongated, continuum, low-gravimetric anomaly defined here as the New Galia Basin and by a sub-circular feature, considered as an extension of the Alvear

  6. Airborne gamma-ray spectrometer and magnetometer survey: San Luis Obispo (California), Santa Maria (California). Final report

    International Nuclear Information System (INIS)

    An airborne combined radiometric and magnetic survey was performed over the area covered by the Santa Maria and San Luis Obispo, California 1:250,000 National Topographic Map Series (NTMS) 10 x 20 quadrangle maps. The survey was a part of DOE's National Aerial Radiometric Reconnaissance program, which is in turn a part of the National Uranium Resource Evaluation (NURE) program. Data were collected by a helicopter equipped with a gamma-ray spectrometer having a large crystal volume, and a high sensitivity proton precession magnetometer. The radiometric system was calibrated at the Walker Field Calibration pads and the Lake Mead Dynamic Test range. Data quality was ensured throughout the survey by daily test flights and equipment checks. Radiometric data were corrected for live time, aircraft and equipment background, cosmic background, atmospheric radon, Compton scatter, and altitude dependence. The corrected data were statistically evaluated, plotted and contoured to produce anomaly maps based on the radiometric response of individual geological units. These maps were interpreted and an anomaly interpretation map produced. Volume I contains a description of the systems used in the survey, a discussion of the calibration of the systems, the data processing procedures, the data display format, the interpretation rationale, and the interpretation methodology. A separate Volume II for each quadrangle contains the data displays and the interpretation results

    2016-08-01

    Violence against women is a worldwide problem due to its impact on quality of life for those living under the complicity of a patriarchal culture and a state that makes such violence invisible. This article aims to give visibility to the contexts of violence affecting female "partners of migrants" in their places of origin, problematizing how such violence assaults their physical and mental health. This was a qualitative study with an interpretative anthropological focus, drawing on a sample of 21 women from rural and urban areas in San Luis Potosí, Mexico. Interviews were based on daily life history and discourse analysis. According to the results, women experience more violence when their spouses migrate, new forms of violence are committed against them, and the violence occurs in both the household and the community. Violence against women is a public health problem that should be treated through a framework that is sensitive to the social and cultural dynamics characterizing the contexts in which health programs are implemented.

    A feasibility study was performed to evaluate the potential of multipurpose applications of moderate-temperature geothermal waters in the vicinity of the Baca Grande community development in the San Luis Valley, Colorado. The project resource assessment, based on a thorough review of existing data, indicates that a substantial resource likely exists in the Baca Grande region capable of supporting residential and light industrial activity. Engineering designs were developed for geothermal district heating systems for space heating and domestic hot water heating for residences, including a mobile home park, an existing motel, a greenhouse complex, and other small commercial uses such as aquaculture. In addition, a thorough institutional analysis of the study area was performed to highlight factors which might pose barriers to the ultimate commercial development of the resource. Finally, an environmental evaluation of the possible impacts of the proposed action was also performed. The feasibility evaluation indicates the economics of the residential areas are dependent on the continued rate of housing construction. If essentially complete development could occur over a 30-year period, the economics are favorable as compared to existing alternatives. For the commercial area, the economics are good as compared to existing conventional energy sources. This is especially true as related to proposed greenhouse operations. The institutional and environmental analyses indicates that no significant barriers to development are apparent.

  9. Geochemistry of uranium in ground waters of the Conlara river Valley, San Luis and Cordoba provinces (Argentina)

    International Nuclear Information System (INIS)

    Geochemical characteristics of ground waters related with lixiviation, transport and precipitation of uranium in the Conlara river valley (provinces of San Luis and Cordoba (Argentina)) are studied. Anions and cations' distributions, together with hardness, specific conductivity, pH, Eh, and uranium and vanadium contents, have been studied. Those parameters characterize four hidrogeochemical facies along an E-W profile: a calcic strong bicarbonate facies, an alkaline-calcic bicarbonate facies, an alkaline sulfate facies, and a strong alkaline sulfate facies. An ''Interphase zone'' (transition from bicarbonate water to sulfate water), where changes in composition may define a geochemical environment capable of UO2 precipitation, has been determined. The chemical-Thermodynamic studies give a dominance of UDC and UTC complexs ions (even in sulfate waters), so they represent the 99% of present ions. Besides, the calculated values required for equilibrium with uraninite or carnotite resulted much greater than those obtained in the performed experiments. It means that the precipitation of those minerals requires either the presence of greate amounts of uranium or vanadium, or a reducing environment with Eh values smaller than the observed ones. Finally, the steps to be taken in future investigations are suggested in view to a drilling plan where: 1) Priority to the ''Interphase zone'' areas is given. 2) The deepest aquifers in Tertiary sediments of the basin have to be reached in order to get the convenient environmental conditions (i.e. smallest Eh values) for uranium or uranium-vanadium precipitation.

    Organochlorine pesticides were intensively used in Mexico from 1950 until their ban and restriction in 1991. However, the presence of these compounds is commonly reported in many regions of the country. The aim of the present study was to identify and quantify residual organochlorine and organophosphorus pesticides in agricultural soil in Rio Verde region, San Luis Potosi state, which has been identified as possibly polluted by pesticides. Composed samples from 24 zones covering an area of approximately 5,440 ha were analyzed. The most frequently found pesticides were p,p'-DDT followed by ,p,p'-DDE, heptachlor, endosulfan and γ-HCH whose frequency rates were 100, 91, 83 and 54%, respectively. The concentration of p,p'-DDT in the crops grown in these soils was in the following order: chili > maize > tomato > alfalfa. The results obtained in this study show that p,p'-DDT values are lower or similar to those found in other agricultural regions of Mexico. Methyl and ethyl parathion were the most frequent organophosphate pesticide detected in 100% and 62.5% of the samples with average concentrations of 25.20 and 47.48 μg kg(-1), respectively. More research is needed to establish the background levels of pesticides in agricultural soils and their potential ecological and human health effects in this region. PMID:24813984

    The Snake Nest Wall site and the Crestone Stone Huts are in the northern San Luis Valley, Colorado, and provide a unique opportunity to date high-altitude archeological sites of unknown age and origin using optically stimulated luminescence (OSL). We sampled sediment underlying foundation stones of these structures to establish a chronological framework for each site's construction. OSL dating of the quartz grains directly under the Snake Nest Wall suggest that the stones and, therefore, the structure was most recently emplaced between 1855 and 1890 A.D. Dating of the sediment beneath the Crestone Stone Huts suggests the construction time of these huts is between 1860 and 1890 A.D. Analysis of the equivalent dose (DE) dispersion of the OSL samples at Snake Nest Wall and the Crestone Huts shows that the majority of sediments were fully bleached prior to deposition and the low scatter suggests that short-term or shallow alluvial processes were the dominant transport for sediments. In both cases, the OSL ages show that the construction was during very recent historical times, although it is likely that the Snake Nest Wall was rebuilt in the late 19th century. Further study is warranted at the Snake Nest Wall since it shows signs of greater antiquity and a continued presence of human use. The Crestone Huts are shown to be a product of railroad building during the boomtown days of Lucky and Crestone.

    This report is about the social acceptance of utility-scale concentrating solar power (CSP) plants in the San Luis Valley, approximately 200 miles southwest of Denver, Colorado. The research focused on social factors that may facilitate and impede the adoption and implementation of CSP. During the winter of 2008-2009, interviews were conducted with a purposive sample of 25 CSP-related stakeholders inside and outside the Valley. Interviews focused on the perceived advantages and disadvantages of siting a hypothetical 100-MW CSP facility in the Valley, the level of community support and opposition to CSP development, and related issues, such as transmission. State policy recommendations based on the findings include developing education programs for Valley residents, integrating Valley decision makers into an energy-water-land group, providing training for Valley decision makers, offering workforce training, evaluating models of taxation, and forming landholder energy associations. In addition, the SLV could become a laboratory for new approaches to CSP facility and transmission siting decision-making. The author recommends that outside stakeholders address community concerns and engage Valley residents in CSP decisions. Engaging the residents in CSP and transmission decisions, the author says, should take parallel significance with the investment in solar technology.

    The aim of this study was to assess the levels of polybrominated diphenyl ethers (PBDEs) in soils from the city of San Luis Potosi in Mexico and perform an ecological and human health risk characterization. In order to confirm the presence of PBDEs, outdoor surface soil samples were collected and the concentrations of PBDEs in urban, industrial, agricultural, and brick kiln industry areas were determined. The mean total PBDEs levels obtained in the study sites were 25.0 ± 39.5 μg/kg (geometric mean ± standard deviation) in the brick kiln industry zone; 34.5 ± 36.0 μg/kg in the urban zone; 8.00 ± 7.10 μg/kg in the industrial zone and 16.6 ± 15.3 μg/kg in the agricultural zone. The ecological and human health risk characterization showed relatively low-hazard quotient values. However, the moderately high PBDEs levels found in soils highlight the necessity to establish a systematic monitoring process for PBDEs in environmental and biological samples. PMID:26566197

    Full Text Available El Granito Tres Cerritos está ubicado en el extremo SE de la Sierra de Quilmes, en el departamento Santa María, provincia de Catamarca, en el ambiente morfoestructural de Sierras Pampeanas Septentrionales. El basamento metamórfico de la zona de estudio está constituido por esquistos de bajo y mediano grado metamórfico pertenecientes al Complejo Tolombón, que son afectadas por una faja de cizalla formada con anterioridad al emplazamiento del intrusivo. Localmente se produce metamorfismo de contacto con formación de porfiroblastos de cordierita y biotita. El granito Tres Cerritos aflora en dos sectores, uno de mayor extensión, de unos 6 km² de superficie, de forma elongada con su eje mayor de 4 km de rumbo submeridional y otro más pequeño, que aflora al oeste del área de estudio, de unos 1,9 Km de largo por 250 m de ancho, aproximadamente. Composicionalmente varía entre sienogranito y monzogranito y presenta tres facies: Porfírica biotítica, porfírica moscovítica y equigranular moscovítica. Geoquímicamente se define como un granito calco-alcalino y peraluminoso, con alto potasio. Según dataciones K/Ar este granito sería de edad carbonífera superior. Las características petrográficas, geoquímicas y geocronológicas del granito Tres Cerritos son similares a la de los intrusivos devónico-carboníferos de las Sierras Pampeanas de Catamarca, La Rioja, Córdoba y San Luis, por lo que el granito Tres Cerritos formaría parte de un evento magmático de gran extensión areal, post-orogénico o de intraplaca, que afectó a las Sierras Pampeanas durante el Devónico-Carbonífero.

Sin embargo, es común que los territorios rurales cuenten con un tejido asociativo desarticulado que limita esas posibilidades. Por lo anterior se planteo conocer las causas de la escasa participación de la sociedad en grupos organizados y la problemática que enfrentan las organizaciones asentadas en un territorio, a través de un estudio de caso en el municipio de Salinas, San Luis Potosí, México, en 2009. El objetivo de este trabajo es identificar las causas que están originando que la organización no tenga impacto en el municipio, lo que permitirá formular una estrategia para lograr que ésta sea un motor de desarrollo en el territorio. Los resultados indican que la mayoría de las personas no participan en ningún tipo de organización aún cuando les gusta trabajar en grupo. En general, las organizaciones se enfrentan a dificultades para tomar acuerdos y cumplir los compromisos adquiridos. Las organizaciones formales en el municipio incluyen organizaciones económicas y de representación.

The metamorphic grade ranges from the lower limit of greenschist facies through the upper limit of amphibolite facies, in apparent transition. The lower grade metamorphic rocks include slates, metavolcanics, metaconglomerates, quartzites and phyllites. Rocks with intermediate metamorphism are biotite-quartz-oligoclase schists with abundant pegmatoid veins. The higher grade metamorphism is represented by gneisses, amphibolites and migmatites, to which mafic and ultramafic bodies are associated. Three deformation phases have been recognized, being the last one (D3, of ordovician age, responsible of the most marked structures.The granitoids were grouped into pre-, syn- and post-kynematic bodies respect to D3. The pre-kynematic granitoids are located within the belt of lower grade metamorphic rocks and are composed of tonalites, granodiorites and monzogranites, strongly deformed. Their age is unknown. The syn-kynematic bodies are mainly garnet-moscovite-bearing leucogranodiorites. They show low thermal and rheological contrasts respect to the country rocks, and the age is 454 ± 21 m.a. The post-kynematic granitoids are mainly monzogranites with K-feldspar megacrysts and abundant sphene. They are subcircular and discordant, and are associated with an extensional regime. Their age is comprised between 423 and 320 m.a., and corresponds to the end of the Famatinian cycle.El basamento cristalino de la parte sur de la Sierra de San Luis, de edad Paleozoico Inferior, está constituido por rocas metamórficas, granitoides y rocas ultramáficas.

The study was undertaken in three zones: Morales, an urban area close to the smelter complex; Graciano, an urban area 7 km away from the complex; and Mexquitic, a small rural town 25 km away. The environmental study showed that Morales is the most contaminated of the zones studied. The range of arsenic levels in soil (117-1396 ppm), dust (515-2625 ppm), and air (0.13-1.45 micrograms/m3) in the exposed area (Morales) was higher than those in the control areas. Cadmium concentrations were also higher in Morales. Estimates of the arsenic ingestion rate in Morales (1.0-19.8 micrograms/kg/day) were equal to or higher than the reference dose of 1 microgram/kg/day calculated by the Environmental Protection Agency. The range of arsenic levels in urine (69-594 micrograms/g creatinine) and hair (1.4-57.3 micrograms/g) and that of cadmium in hair (0.25-3.5 micrograms/g) indicated that environmental exposure has resulted in an increased body burden of these elements in children, suggesting that children living in Morales are at high risk of suffering adverse health effects if exposure continues.

    Asserting mobility of ancient humans is a major issue for anthropologists. For more than 25 years, Sr isotopes have been used as a resourceful tracer tool in this context. A comparison of the 87Sr/86Sr ratios found in tooth enamel and in bone is performed to determine if the human skeletal remains belonged to a local or a migrant. Sr in bone approximately reflects the isotopic composition of the geological region where the person lived before death; whereas the Sr isotopic system in tooth enamel is thought to remain as a closed system and thus conserves the isotope ratio acquired during childhood. Sr isotope ratios are obtained through the geologic substrate and its overlying soil, from where an individual got hold of food and water; these ratios are in turn incorporated into the dentition and skeleton during tissue formation. In previous studies from Teotihuacan, Mexico we have shown that a three-step leaching procedure on tooth enamel samples is important to assure that only the biogenic Sr isotope contribution is analyzed. The same Sr isotopic tools can function concerning ancient animal migration patterns. To determine or to discard the mobility of prairie mammoths (Mammuthus columbi) found at Laguna de las Cruces, San Luis Potosi, México the leaching procedure was applied on six molar samples from several fossil remains. The initial hypothesis was to use 87Sr/86Sr values to verify if the mammoth population was a mixture of individuals from various herds and further by comparing their Sr isotopic composition with that of plants and soils, to confirm their geographic origin. The dissimilar Sr results point to two distinct mammoth groups. The mammoth population from Laguna de Cruces was then not a family unit because it was composed by individuals originated from different localities. Only one individual was identified as local. Others could have walked as much as 100 km to find food and water sources.

    Full Text Available El yacimiento de sulfuros Las Águilas se halla emplazado en el sector sur de las Sierras Grandes de San Luis. La exploración geofísica de este yacimiento presenta numerosos problemas debido a su estructura, al tipo de mineralización de las rocas ultramáficas y a su composición mineralógica. Los métodos de polarización inducida son eficientes en la ubicación de mineralizaciones de sulfuros polimetálicos, pero necesitan de la concurrencia de otras metodologías geofísicas para resolver el problema que puede conllevar la existencia de grafito como elemento indeseable en la evaluación de este yacimiento. Esta investigación se basa en la comparación de los resultados de las prospecciones de polarización inducida (PI y las magnéticas. El análisis de los resultados de los perfiles indica que en zonas donde de las rocas tienen alta susceptibilidad magnética ésta es debida a la presencia de sulfuros (pirrotina. La presencia del grafito es irrelevante para la prospección magnética debido a su naturaleza diamagnética. Esta situación se ve también reflejada al comparar las anomalías magnéticas con los parámetros de polarización inducida (resistividad, factor metálico y al porcentaje de la Variación de la Resistividad por Efecto de la Frecuencia (PVREF, siendo posible deducir que la pirrotina es la causante de las anomalías de (PI, asumiendo que en el yacimiento no coexisten el grafito y los sulfuros y que la magnetita no se encuentre en altas concentraciones.

    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.

    Background and Objectives The Little Bonanza mercury (Hg) mine, located in San Luis Obispo County, California, is a relatively small mine with, a historical total Hg production of about 1,000 flasks. The mine workings and tailings are located in the headwaters of the previously unnamed west fork of Las Tablas Creek (WF Las Tablas Creek), which flows into the Nacimiento Reservoir. Wasterock and tailings eroded from the Little Bonanza Hg Mine have contributed Hg-enriched mine wastes to the headwaters of WF Las Tablas Creek. The mine is located on Federal land managed by the U.S. Bureau of Land Management (BLM), which requested that the U.S. Geological Survey (USGS) measure and characterize Hg and other geochemical constituents in tailings, sediment, water, and biota at and downstream from the minesite. This report is in response that request, from the lead agency which is mandated to conduct a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - Removal Site Investigation (RSI). The RSI applies to removal of Hg-contaminated mine waste from the Little Bonanza minesite as a means of reducing Hg transport to WF Las Tablas Creek. This report summarizes data obtained from field sampling of mine tailings, wasterock, sediment, water, and biota at the Little Bonanza Mine that was completed on April 6, 2010. Conditions during sampling were dry and no rain had occurred in the watershed for several weeks. Our results permit a preliminary assessment of the mining sources of Hg and associated chemical constituents that could produce elevated levels of monomethyl mercury (MMeHg) in WF Las Tablas Creek and in biota.

  19. Hydrogeology, water quality, water budgets, and simulated responses to hydrologic changes in Santa Rosa and San Simeon Creek ground-water basins, San Luis Obispo County, California

    Yates, Eugene B.; Van Konyenburg, Kathryn M.

    Santa Rosa and San Simeon Creeks are underlain by thin, narrow ground-water basins that supply nearly all water used for local agricultural and municipal purposes. The creeks discharge to the Pacific Ocean near the northwestern corner of San Luis Obispo County, California. The basins contain heterogeneous, unconsolidated alluvial deposits and are underlain by relatively impermeable bedrock. Both creeks usually stop flowing during the summer dry season, and most of the pumpage during that time is derived from ground-water storage. Annual pumpage increased substantially during 1956?88 and is now a large fraction of basin storage capacity. Consequently, dry-season water levels are lower and the water supply is more vulnerable to drought. The creeks are the largest source of ground-water recharge, and complete basin recharge can occur within the first few weeks of winter streamflow. Agricultural and municipal pumpages are the largest outflows and cause dry-season water-level declines throughout the San Simeon Basin. Pumping effects are more localized in the Santa Rosa Basin because of subsurface flow obstructions. Even without pumpage, a large quantity of water naturally drains out of storage at the upper ends of the basins during the dry season. Ground water is more saline in areas close to the coast than in inland areas. Although seawater intrusion has occurred in the past, it probably was not the cause of high salinity in 1988?89. Ground water is very hard, and concentrations of dissolved solids, chloride, iron, and manganese exceed drinking-water standards in some locations. Probability distributions of streamflow were estimated indirectly from a 120-year rainfall record because the periods of record for local stream-gaging stations were wetter than average. Dry-season durations with recurrence intervals between 5 and 43 years are likely to dry up some wells but not cause seawater intrusion. A winter with no streamflow is likely to occur about every 32 years and to

    An estimated 100,000m(3) selenium (Se)-laden drainage sediment resides in the San Luis Drain (SLD) of Central California. This greenhouse study was undertaken to evaluate the feasibility of growing salt- and boron-tolerant plant species in sediment for reduction of Se content by plant extraction. Drainage sediment was collected from the SLD and mixed with control soil (i.e., uncontaminated soil) to the following ratios (sediment:control soil) by volume: 0:3 (i.e., control soil only), 1:2 (i.e., 1/3 sediment and 2/3 control soil), 2:1 (i.e., 2/3 sediment and 1/3 control soil), and 3:0 (i.e., sediment only). Salt-tolerant plant species consisted of canola (Brassica napus var. Hyola 420), tall fescue (Festuca arundinacea var. Au Triumph), salado grass (Sporobulus airoides), and cordgrass (Spartina patens var. Flageo). Increased ratios of sediment:soil resulted in decreased dry matter production for all tested plant species; especially at ratios of sediment:soil greater than 1:2. Plant Se concentrations (mgkg(-1) DM) ranged as follows for plant species at all ratios of sediment:soil: canola (51-72), tall fescue (16-36), and cordgrass and salado grass (9-14). Total Se concentrations in the soil were at least 20% lower at postharvest compared to preplant concentrations for all plant species at each ratio of sediment:soil. In contrast, water-extractable Se concentrations in the soil were at least three times higher at postharvest than at preplant for all plant species, irrespective of the ratio of sediment:soil. Leaching of Se occurred in irrigated bare pots from each respective ratio of sediment:soil over a duration of 60 days. Based upon the downward movement of Se in bare pots of sediment:soil, it may be more prudent to leave the drainage sediment in the SLD, incorporate clean soil, and then grow low maintenance salt-tolerant plants (e.g., cordgrass, salado grass) in the concrete-lined canal. By this means, possible contamination of groundwater with soluble Se will be

  2. A multi-dimensional analysis of the upper Rio Grande-San Luis Valley social-ecological system

    Science.gov (United States)

    Mix, Ken

    The Upper Rio Grande (URG), located in the San Luis Valley (SLV) of southern Colorado, is the primary contributor to streamflow to the Rio Grande Basin, upstream of the confluence of the Rio Conchos at Presidio, TX. The URG-SLV includes a complex irrigation-dependent agricultural social-ecological system (SES), which began development in 1852, and today generates more than 30% of the SLV revenue. The diversions of Rio Grande water for irrigation in the SLV have had a disproportionate impact on the downstream portion of the river. These diversions caused the flow to cease at Ciudad Juarez, Mexico in the late 1880s, creating international conflict. Similarly, low flows in New Mexico and Texas led to interstate conflict. Understanding changes in the URG-SLV that led to this event and the interactions among various drivers of change in the URG-SLV is a difficult task. One reason is that complex social-ecological systems are adaptive, contain feedbacks, emergent properties, cross-scale linkages, large-scale dynamics and non-linearities. Further, most analyses of SES to date have been qualitative, utilizing conceptual models to understand driver interactions. This study utilizes both qualitative and quantitative techniques to develop an innovative approach for analyzing driver interactions in the URG-SLV. Five drivers were identified for the URG-SLV social-ecological system: water (streamflow), water rights, climate, agriculture, and internal and external water policy. The drivers contained several longitudes (data aspect) relevant to the system, except water policy, for which only discreet events were present. Change point and statistical analyses were applied to the longitudes to identify quantifiable changes, to allow detection of cross-scale linkages between drivers, and presence of feedback cycles. Agricultural was identified as the driver signal. Change points for agricultural expansion defined four distinct periods: 1852--1923, 1924--1948, 1949--1978 and 1979

    Full Text Available En la provincia de San Luis, existen tres sub-cuencas denominadas Las Salinas, Beazley y Mercedes. Estas cuencas corresponden a depocentros de rift elongados en sentido NO, que alojan rocas ígneas de edad triásica con espesores que llegan hasta los 4.000 metros. Las rocas ígneas de la Formación Cerro Varela forman parte del cerro homónimo que constituye los últimos asomos australes de la sierra de San Luis. Las riolitas triásicas que afloran en la sierra de Varela se disponen dentro de un esquema estructural extensional asociado a la formación de cuencas de tipo rift. Las unidades analizadas de la Formación Cerro Varela están compuestas por tobas cristalinas tanto de alto grado como de bajo grado de soldadura, de composición riolítica e interpretadas como depósitos originados por flujos piroclásticos. Por su litología, edad y contexto regional, las rocas de la Formación Cerro Varela integran el magmatismo gondwánico del Grupo Choiyoi de edad permotriásica de la Cordillera Frontal de Mendoza y San Juan.In the San Luis province, there are three sub-basins called Las Salinas, Beazley and Mercedes. These basins correspond to elongated rift depocenter with a NO orientation that host Triassic igneous rocks with thicknesses that reach 4,000 meters. The igneous rocks from Cerro Varela Formation, part of the homonym hill, is the last vestige of the southern Sierra San Luis. The Triassic rhyolites that crop up in the sierra de Varela, are placed within a structural pattern associated with the formation of extensional basins. Crystal tuffs of Cerro Varela are corresponds to tuffs with high and low degree of welding, of rhyolitic composition and interpreted as pyroclastic deposits. For its lithology, age and regional context, the rocks of the Cerro Varela Formation integrate the Gondwanic magmatism of Permo-Triassic age, related to the Choiyoi Group of the Cordillera Frontal of Mendoza and San Juan.

    interpretation of the geology, mineralogy and geochemistry of the Las Cuevas pegmatite, Conlara pegmatitic district, Sierra de San Luis, Argentina. This ore deposit belongs to the Rare-Element class, REL-Li subclass, complex type, spodumene-subtype of granitic pegmatites. it is a tabular bodie trending to the northwest, with dips ranging from vertical to subhorizontal. The host-rocks of the pegmatite are usually quartz-micaceous schists. The depth of emplacement was in the ductile to brittle transition domain, possibly ranging between 7 and 12 km. The intrusion of the pegmatite was forced, producing secondary folding in the host rock and enclosing metric-sized xenoliths. The emplacement took place during the Eopaleozoic, shortly after the regional metamorphic peak of the Famatinian Cycle. The pegmatite and its host-rock were deformed by the late tectonism belonging to the Ocloyic phase. Eight zones of different mineral association, texture and setting have been identified in this pegmatite. The mineralogy comprises: quartz, microcline, spodumene, albite, muscovite, apatite, beryl, schörl, zircon, garnet, columbite-(Mn, tantalite-(Mn, pyrochlore and microlite group minerals, ambligonite-montebrasite, triphylite-litiophilite, elbaite, eucriptite, lepidolite, bismuthinite, pyrite, huréaulite, phosphosiderite, beraunite, rockbridgeite, stewartite, bismutite, ferric oxides, manganese oxides, and mitridatite.The processes of pegmatitic differentiation, indicated by the chemical composition of trace elements in K-feldspar and muscovite, are comparable and do not differ from the known paths of similar world- and argentinian- pegmatites of this type showing lineal fractionation trends. Besides, the individual analysis shows a lineal differentiation, in some cases with an overprint between the samples of different zones, resulting from changes in the physico-chemical conditions of cristalization. Based on the muscovite geochemistry, Las Cuevas has an interesting but limited potential

    Prologue Welcome to the 2007 Rocky Mountain Cell Friends of the Pleistocene Field Trip, which will concentrate on the Quaternary geology of the San Luis Basin of Colorado and New Mexico. To our best knowledge, Friends of the Pleistocene (FOP) has never run a trip through the San Luis Basin, although former trips in the region reviewed the 'Northern Rio Grande rift' in 1987 and the 'Landscape History and Processes on the Pajarito Plateau' in 1996. After nearly a decade, the FOP has returned to the Rio Grande rift, but to an area that has rarely hosted a trip with a Quaternary focus. The objective of FOP trips is to review - in the field - new and exciting research on Quaternary geoscience, typically research being conducted by graduate students. In our case, the research is more topically oriented around three areas of the San Luis Basin, and it is being conducted by a wide range of Federal, State, academic, and consulting geologists. This year's trip is ambitious?we will spend our first day mainly on the Holocene record around Great Sand Dunes National Park and Preserve, the second day on the Quaternary stratigraphy around the San Luis Hills, including evidence for Lake Alamosa and the 1.0 Ma Mesita volcano, and wrap up the trip's third day in the Costilla Plain and Sunshine Valley reviewing alluvial stratigraphy, the history of the Rio Grande, and evidence for young movement on the Sangre de Cristo fault zone. In the tradition of FOP trips, we will be camping along the field trip route for this meeting. On the night before our trip, we will be at the Great Sand Dunes National Park and Preserve's Pinyon Flats Campground, a group facility located about 2 miles north of the Visitors Center. After the first day's trip, we will dine and camp in the Bachus pit, about 3 miles southwest of Alamosa. For the final night (after day 2), we will bed down at La Junta Campground at the Bureau of Land Management (BLM) Wild and Scenic Rivers State Recreation Area, west of Questa

    2012-08-01

    At La Melada, Sierra de San Luis, Argentina, two lenses of mafic-ultramafic rocks, which underwent Famatinian metamorphism followed by shear deformation, form part of a NNE-SSW-trending belt along the eastern flank of the Sierra. Metapyroxenites from the lenses are granoblastic rocks made up of igneous and metamorphic minerals, with varying degrees of deformation and mylonitization. These rocks preserve evidence of post-magmatic re-equilibration that followed the emplacement of the mafic-ultramafic rocks. Microstructural investigation and P-T pseudosection modelling suggest that La Melada metapyroxenites experienced a temperature and pressure decrease from the M0 (800 °C talc + cummingtonite during the M2 stage and to the development of metamorphic plagioclase and dolomite in the post-M2 stage. The P-T segment reconstructed for La Melada metapyroxenites is consistent with a back-arc setting and with P-T paths previously reported in the literature.

    Full Text Available Los mapas aeromagnéticos disponibles de las sierras de San Luis y Comechingones en el sector sudoriental de las Sierras Pampeanas de Argentina, permiten examinar las características geológicas y estructurales de las unidades metamórficas e intrusivas del basamento de la región. A través de la aplicación del filtro de continuación ascendente a los datos del campo magnético total reducido al polo, se ha podido observar la configuración profunda de las distintas unidades. Entre ellas se destaca la secuencia supracortical, en parte correspondiente a la Formación San Luis, que permite reconstruir en varios sectores de la región, en algunos casos subaflorante, una importante sucesión de rocas metasedimentarias de hasta 3 km de espesor, que es interpretada como perteneciente a depósitos de una cuenca de antepaís formada con posterioridad a la orogenia pampeana, alrededor de los 530 Ma. Se caracterizan las distintas unidades metamórficas e ígneas a partir de su señal magnética, y sobre esta base se presenta una sección estructural profunda, que sirve de base para proponer la evolución tectónica del basamento de este sector de las Sierras Pampeanas. Éste registra a partir de la orogenia pampeana la instalación de un arco magmático con su respectiva cuenca de trasarco durante el Cámbrico tardío y el Ordovícico temprano, los que son cerrados y deformados durante la colisión del terreno de Cuyania en el Ordovícico medio.

    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 Se ha realizado una revisión integral de la información geológica para el basamento ígneo-metamórfico de la Sierra de San Luis y esto permite elaborar un modelo de evolución dividido en tres etapas: 1 Procesos pre-famatinianos: Sedimentación siliciclástica original, con intercalaciones de lavas máficas a ultramáficas y depositación de estratos de Fe bandeado. Su edad podría ser precámbrica. Son escasos los controles isotópicos pampeanos para la estructuración relíctica NO y el metamorfismo asociado. Por otro lado, se verifica una sedimentación durante el ciclo Pampeano. 2 Ciclo orogénico Famatiniano, fase principal: Es la que imprime los rasgos más notables del basamento. El arco magmático famatiniano se instala ya con anterioridad a los 507 Ma (Cámbrico medio, y el Ordovícico constituye el apogeo de las actividades ígneas, tectónicas y metamórficas regionales. Se deforman los granitoides junto con su roca de caja, y se estructura la sierra mediante foliación penetrativa de rumbo NNE. 3 Ciclo Famatiniano, etapa tardía a posorogénica: Entre el Silúrico y el Carbonífero temprano las actividades orogénicas son de relevancia menor. Los esfuerzos compresivos finales se disipan a través de grandes zonas de cizalla dúctil, yuxtaponiendo y exhumando las fajas de rocas metamórficas. Se emplazan a su vez, granitoides tardío- a posorogénicos. Desde el punto de vista regional, la deformación ordovícica de las Sierras Pampeanas fue vinculada a colisión de terrenos. La Sierra de San Luis se ubica en el margen proto-andino del autóctono de Gondwana, en donde se instaló el arco magmático. La deformación ordovícica afectó tanto a este borde de Gondwana como diferencialmente al basamento mesoproterozoico del terreno acrecionado de Cuyania, ubicado al oeste. Hacia el este de la Sierra de San Luis, la Sierra de Córdoba ya no fue directamente involucrada en el eje orogénico famatiniano, por lo cual en ella se preservan

    Full Text Available Emplazada en la zona de transición sur del segmento de flat-slab pampeano y directamente vinculada a la horizontalización de la placa de Nazca, la faja volcánica terciaria de San Luis delata la migración que experimentó el arco magmático andino a la latitud de los 33º S en tiempos mio-pliocenos. Esta faja volcánica comprende una serie de distritos metalogenéticos de gran importancia en las Sierras Pampeanas de San Luis. Las rocas volcánicas y mineralizaciones de la faja volcánica terciaria se encuentran representadas en los campos volcánicos La Carolina, Cañada Honda - Cerros Largos, Cerros del Rosario y El Morro, dispuestos saltuariamente según una dirección ONO-NO. Las edades K-Ar disponibles indican que el volcanismo se habría iniciado más tempranamente en el sector occidental de esta faja, y que habría finalizado ~ 10 Ma más tarde en la región oriental. El distrito Cañada Honda, el más antiguo y longevo de esta faja volcánica, registra eventos volcánicos e hidrotermales cuyas edades varían entre 12-13 Ma y 7,3 Ma, abarcando facies lávico-hipabisales y volcaniclásticas. Los resultados del análisis estructural demuestran el importante control que, directa o indirectamente, habrían ejercido las estructuras previas en el emplazamiento de las rocas volcánicas y mineralizaciones. Análisis de fábrica deformacional y cinemático han permitido reconocer dos asociaciones volcano-tectónicas diferentes. una de estas asociaciones se vincularía a la reactivación dextral de estructuras paralelas a la foliación del basamento. La asociación principal estaría vinculada con el desarrollo de dos depresiones volcano-tectónicas alineadas en dirección ONO-NO. Sus estructuras principales, de orientación ONO-NO, revelan componentes de desplazamiento senestral y normal tanto a escala del distrito Cañada Honda como de la faja volcánica terciaria.

    This report describes data collected from a high-resolution aeromagnetic survey flown over the central San Luis basin during October, 2004, by PRJ, Inc., on contract to the U.S. Geological Survey (USGS). The survey extends from just north of Alamosa, Colorado, southward to just northwest of Taos, New Mexico. It covers large parts of the San Luis Valley in Alamosa, Conejos, Costilla, and Rio Grande Counties, southern Colorado, and the Taos Plateau in Taos County, northern New Mexico. The survey was designed to complement two surveys previously acquired along the eastern borders of the San Luis Basin over the vicinities of Taos, New Mexico (Bankey and others, 2004a) and Blanca, Colorado (Bankey and others, 2004b). Our overall objective in conducting these surveys is to improve knowledge of the subsurface geologic framework in order to understand ground-water systems in populated alluvial basins along the Rio Grande. These USGS efforts are conducted in collaboration with other federal, state, and local governmental entities where possible.

    Full Text Available 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.

    Full Text Available Las características del ambiente natural y construido son el resultado del comportamiento humano individual, familiar y colectivo, pero al mismo tiempo dichas características ambientales influyen de forma decisiva en las conductas cotidianas de los individuos y los grupos, dando lugar a una reciprocidad entre el ambiente y la conducta humana. Desde mediados del siglo pasado, comienza a incorporarse el medio ambiente como variable que tiene gran influjo en la calidad de vida humana, manifestando efectos sobre la totalidad de las dimensiones de la misma. El objetivo del presente trabajo fue explorar la percepción de la calidad de vida en un grupo de individuos, de la ciudad capital de San Luis (Argentina, según el género y la edad de los mismos. Se aplicó la versión argentina del WHOQOL-100 (Bonicatto y Soria, 1998. Los resultados mostraron que ambas variables demográficas tienen gran impacto en la satisfacción de la calidad de vida de los individuos.

    Full Text Available Un perfil gravimétrico y magnetométrico realizado en el sector noroeste de la Sierra Grande de San Luis mostró máximos relativos de gravedad en una zona donde se hallan afloramientos de rocas máficas-ultramáficas incluidas en cuerpos graníticos ordovícicos. Asimismo se pudo comparar las anomalías gravimétricas de Bouguer con las del campo magnético terrestre. Los modelos geofísicos fueron elaborados en base a las densidades determinadas para las rocas aflorantes en esta región (granitoides, gneises, máficas y ultramáficas y el valor teórico para la corteza superior. Como resultado se sugiere que las inclusiones de rocas máficas-ultramáficas en los cuerpos graníticos representan el 40 % del volumen de estas últimas. Por ello se considera que el área de pampa de las Invernadas es potencialmente interesante desde el punto de vista económico debido a que las anomalías gravimagnetométricas indican la posibilidad de hallar en profundidad rocas máficas-ultramáficas mineralizadas dado que los parámetros geofísicos medidos son similares a los obtenidos en el área de Río de Las Águilas, en el sector sur de estas sierras.

    The purpose of this study was to evaluate the impact of acid mine drainage on the chemistry and the macrobenthos of the Carolina stream (San Luis - Argentina). Samples were obtained in the years 1997-1998 at two sites: site C(1), located 200 m upstream of the drainage, and site C(2), located 800 m downstream. The system buffer capacity was evaluated in the non - contaminated site by means of the buffer index calculation. The physico - chemical changes observed as a consequence of the contribution of acid mine drainage (AMD) were: a decreasing of pH and an increase in the ionic concentration, especially sulfate and Fe coming from the oxidation produced by chemiolithotrophic bacteria. The values obtained indicated a low buffer capacity and a high intrinsic vulnerability of the system to resist the impact originated by the AMD, producing a remarkable decreasing of pH of the receiving stream. These changes caused modifications in the original benthic community that was replaced by organisms more tolerant to the acid stress. A reduction in the abundance and in the taxonomic richness of the benthic macroinvertebrates was observed when compared with the reference station. An increase in the proportion of Chironomidae and of Acari and a decrease in the proportion of the remaining taxa were observed. The most sensitive groups were Ephemeroptera, Trichoptera and Mollusca. The community was mostly affected by the following variables: pH, conductivity, sulfate and dissolved total Fe. PMID:16565803

    This case study enhances the understanding of open automated demand response opportunities in municipal wastewater treatment facilities. The report summarizes the findings of a 100 day submetering project at the San Luis Rey Wastewater Treatment Plant, a municipal wastewater treatment facility in Oceanside, California. The report reveals that key energy-intensive equipment such as pumps and centrifuges can be targeted for large load reductions. Demand response tests on the effluent pumps resulted a 300 kW load reduction and tests on centrifuges resulted in a 40 kW load reduction. Although tests on the facility?s blowers resulted in peak period load reductions of 78 kW sharp, short-lived increases in the turbidity of the wastewater effluent were experienced within 24 hours of the test. The results of these tests, which were conducted on blowers without variable speed drive capability, would not be acceptable and warrant further study. This study finds that wastewater treatment facilities have significant open automated demand response potential. However, limiting factors to implementing demand response are the reaction of effluent turbidity to reduced aeration load, along with the cogeneration capabilities of municipal facilities, including existing power purchase agreements and utility receptiveness to purchasing electricity from cogeneration facilities.

    Full Text Available Objective. The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico. Materials and Methods. A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L was evaluated. Fluoride exposure was determined by measuring urine fluoride concentration using the potentiometric method with an ion selective electrode. The diagnosis of dental fluorosis was performed by clinical examination, and the severity of damage was determined using Dean’s index and the Thylstrup-Fejerskov (TF index. Results. The range of exposure in the study population, evaluated through the fluoride content in urine, was 1.1 to 5.9 mg/L, with a mean of 3.14 ± 1.09 mg/L. Dental fluorosis was present in all subjects, of which 95% had severe cases. Higher urine fluoride levels and greater degrees of severity occurred in older children. Conclusions. The results show that dental fluorosis was determined by the presence of fluoride exposure finding a high positive correlation between the severity of fluorosis and urine fluoride concentration and the years of exposure suggested a cumulative effect.

    Full Text Available En este trabajo, se analiza la composición isotópica del acuífero del Valle de San Luis Río Colorado en Sonora en conjunto con la concentración de cloruros del agua para determinar el origen del agua del subsuelo y establecer las causas del aumento de salinidad que se ha observado en el agua de riego. La mineralización del acuífero ha provocado un deterioro en la calidad del agua de esta agua. Se encontró que la composición isotópica deja ver un fraccionamiento como consecuencia de la evaporación rápida y la mezcla de aguas antiguas, infiltradas antes de la construcción del sistema de presas, con aguas recientes del Río Colorado, sometidas a un proceso de evaporación en los vasos de éstas. El análisis isotópico permitió establecer que el agua de los canales de riego más mineralizada aún no está presente en el acuífero.In this work, the isotopic composition and chloride concentration of San Luis Rio Colorado, Sonora, in Mexico were used to determine the origin of groundwater and to establish the salinity increase that has been observed in the irrigation water. The aquifer mineralization has provoked deterioration of this water. The isotopic composition showed a fractioning due to the sudden evaporation and the mixing of water percolated before the dam system, constructed upstream, with water infiltrated to the aquifer after evaporation in the reservoirs, these water types are known as old and recent, respectively. Unlike what it could be expected, the isotopic composition determined that mineralized water from irrigation channels is not yet present in the aquifer.

    Full Text Available Native communities’ erosion of ethnobotanical knowledge of food plants is a global concern. This investigation focuses on a Xi’iuy community in the Sierra Madre Oriental, San Luís Potosí, México. A total of 21 randomly-selected families participated (22% of the total population. The 56 people who were interviewed—an average of 2.7 per family-- were separated into four groups (fathers, mothers, single sons, single daughters. To investigate the use value of each plant, a collection of 54 food specimens was shown to the informants. Knowledge of each food species’ uses was compared between genders and age groups. The results included figures that were lower than expected, as well as less knowledge among women than men, particularly among underage daughters. The difference in use value between men and women in this community is explicable by cultural factors: i.e., women’s participation in agriculture and plant collecting is minimal. This, along with men’s seasonal migration for work (men are usually wage laborers half the year in the sugarcane harvest, and the other half they cultivate their own land, plus increasing availability of commercial food in grocery stores, contributes to the steady loss of ethnobotanical knowledge.

    This report provides information on the geology and selected physical and mechanical properties of surface rocks collected at Diablo Canyon, San Luis Obispo County, California as part of the design and engineering studies towards a future reactor neutrino oscillation experiment. The main objective of this neutrino project is to study the process of neutrino flavor transformation or neutrino oscillation by measuring neutrinos produced in the fission reactions of a nuclear power plant. Diablo Canyon was selected as a candidate site because it allows the detectors to be situated underground in a tunnel close to the source of neutrinos (i.e., at a distance of several hundred meters from the nuclear power plant) while having suitable topography for shielding against cosmic rays. The detectors have to be located underground to minimize the cosmic ray-related background noise that can mimic the signal of reactor neutrino interactions in the detector. Three Pliocene-Miocene marine sedimentary units dominate the geology of Diablo Canyon: the Pismo Formation, the Monterey Formation, and the Obispo Formation. The area is tectonically active, located east of the active Hosgri Fault and in the southern limb of the northwest trending Pismo Syncline. Most of the potential tunnel for the neutrino detector lies within the Obispo Formation. Review of previous geologic studies, observations from a field visit, and selected physical and mechanical properties of rock samples collected from the site provided baseline geological information used in developing a preliminary estimate for tunneling construction cost. Gamma-ray spectrometric results indicate low levels of radioactivity for uranium, thorium, and potassium. Grain density, bulk density, and porosity values for these rock samples range from 2.37 to 2.86 g/cc, 1.41 to 2.57 g/cc, and 1.94 to 68.5 percent respectively. Point load, unconfined compressive strength, and ultrasonic velocity tests were conducted to determine rock

Review of previous geologic studies, observations from a field visit, and selected physical and mechanical properties of rock samples collected from the site provided baseline geological information used in developing a preliminary estimate for tunneling construction cost. Gamma-ray spectrometric results indicate low levels of radioactivity for uranium, thorium, and potassium. Grain density, bulk density, and porosity values for these rock samples range from 2.37 to 2.86 g/cc, 1.41 to 2.57 g/cc, and 1.94 to 68.5% respectively. Point load, unconfined compressive strength, and ultrasonic velocity tests were conducted to determine rock mechanical

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 En los cuerpos máficos-ultramáficos del área de Virorco y La Bolsa, bloque central de la sierra de San Luis, se han detectado sulfuros polimetálicos en venillas y diseminados. Como herramienta de prospección geofísica se utilizó el método de autopotencial en combinación con estudios geomagnéticos. Los lentes máfico-ultramáficos están enmarcados por una caja gnéisicamigmatítica de alto grado. Una foliación milonítica de rumbo NNE y buzamiento de alto ángulo al ESE, afecta al basamento y también a los bordes de los cuerpos máfico-ultramáficos. Hacia el interior de estos últimos, alternan sectores que preservan las texturas granulares ígneas y una foliación buzante al oeste, con fajas de cizalla con foliación milonítica buzante al ESE. El estudio geofísico en Virorco indica una correspondencia entre los valores de autopotencial negativos (-150 mV y los máximos de magnetismo terrestre (+350 nT. En la zona de La Bolsa se realizaron dos perfiles de autopotencial, los cuales muestran un núcleo de autopotencial negativo de entre -40 y -55 mV, ligeramente alargado y buzante al ESE. Sobre el margen oriental, un valor de -90 mV constituye el núcleo de una anomalía alargada y también buzante al ESE. La disposición espacial de estas anomalías es coincidente con la orientación de la foliación milonítica. La correspondencia establecida con esta nueva herramienta de prospección, sustenta la removilización y concentración de los sulfuros primarios diseminados durante el evento de milonitización, ya planteada previamente en base a otras técnicas de estudio.In the Virorco and La Bolsa mafic-ultramafic bodies, central block of the Sierra de San Luis, polymetallic sulfides occur in veinlets and disseminated.

    Full Text Available INTRODUCTION: Chagas disease is caused by Trypanosoma cruzi. Wild and perianthropic mammals maintain the infection/transmission cycle, both in their natural habitat and in the peridomestic area. The aim of this paper was to present the results from a study on wild rodents in the central and northern regions of San Luis province, Argentina, in order to evaluate the prevalence of this infection. METHODS: Sherman traps were set up in capture areas located between latitudes 32º and 33º S, and longitudes 65º and 66º W. The captured rodents were taxonomically identified and hemoflagellates were isolated. Morphological, biometric and molecular studies and in vitro cultures were performed. Infection of laboratory animals and histological examination of the cardiac muscle and inoculation area were also carried out. Parasites were detected in circulating blood in Calomys musculinus, Graomys griseoflavus, Phyllotis darwini and Akodon molinae. The parasites were identified using biological criteria. Molecular PCR studies were performed on some isolates, which confirmed the characterization of these hemoflagellates as Trypanosoma cruzi. RESULTS AND CONCLUSIONS: Forty-four percent of the 25 isolates were identified as Trypanosoma cruzi, and the remaining 56% as Trypanosoma cruzi-like. These findings provide evidence that wild rats infected with Trypanosoma cruzi and Trypanosoma cruzi-like organisms are important in areas of low endemicity.INTRODUÇÃO: A doença de Chagas é causada pelo Trypanosoma cruzi e os mamíferos periantrópicos e silvestres mantêm o ciclo de infecção/transmissão, tanto no ambiente natural, como no peridomicílio.

    Full Text Available Gondwanic pyroclastic deposits in southern Sierra de Varela, San Luis province: petrography and geochemistry. This work presents the results of the petrographic and geochemical characterization of the pyroclastic deposits of the Cerro Varela Formation (Anisian, located in the southern portion of the Sierra de Varela, western San Luis province. This unit is linked regionally and chronologically to the Choiyoi Group and also fills the Beazley basin. The base of the Cerro Varela Formation overlies the Precambrian-Lower Paleozoic metamorphic basement and it is covered discordantly by the Upper Cretaceous Lagarcito Formation. In the study area two types of pyroclastic deposits area recognized: crystal-rich welded tuffs and fall deposits, both of rhyolitic composition. The crystal-rich welded tuffs comprise the majority of the outcrops, whereas the fall deposits are morerestricted because of their low degree of preservation. The pyroclastic flow deposits form red-colored layers with eutaxitic texture, columnar jointing and quartz and sanidine phenocrysts in a micrograin, felsitic and granophyric matrix with abundant iron oxides. Felsic volcanic lithic cognates and devitrified vitroclasts are also observed. The fall deposits are solid, orange-colored layers of fine grain size, with underformed vitreous fragments and quartzcrystaloclasts. The chemistry of the pyroclastic units is comparable to the middle to upper section transition of the Permo-Triassic Choiyoi Group in the Cordillera Frontal of Mendoza and San Juan. Their environment of generation is linked to rifting phenomena in a normal to thin crust where extension can be associated with the firststage of break-up of Gondwana during the Mesozoic.

    Full Text Available Se ha realizado una revisión integral de la información geológica para el basamento ígneo-metamórfico de la Sierra de San Luis y esto permite elaborar un modelo de evolución dividido en tres etapas: 1 Procesos pre-famatinianos: Sedimentación siliciclástica original, con intercalaciones de lavas máficas a ultramáficas y depositación de estratos de Fe bandeado. Su edad podría ser precámbrica. Son escasos los controles isotópicos pampeanos para la estructuración relíctica NO y el metamorfismo asociado. Por otro lado, se verifica una sedimentación durante el ciclo Pampeano. 2 Ciclo orogénico Famatiniano, fase principal: Es la que imprime los rasgos más notables del basamento. El arco magmático famatiniano se instala ya con anterioridad a los 507 Ma (Cámbrico medio, y el Ordovícico constituye el apogeo de las actividades ígneas, tectónicas y metamórficas regionales. Se deforman los granitoides junto con su roca de caja, y se estructura la sierra mediante foliación penetrativa de rumbo NNE. 3 Ciclo Famatiniano, etapa tardía a posorogénica: Entre el Silúrico y el Carbonífero temprano las actividades orogénicas son de relevancia menor. Los esfuerzos compresivos finales se disipan a través de grandes zonas de cizalla dúctil, yuxtaponiendo y exhumando las fajas de rocas metamórficas. Se emplazan a su vez, granitoides tardío- a posorogénicos. Desde el punto de vista regional, la deformación ordovícica de las Sierras Pampeanas fue vinculada a colisión de terrenos. La Sierra de San Luis se ubica en el margen proto-andino del autóctono de Gondwana, en donde se instaló el arco magmático. La deformación ordovícica afectó tanto a este borde de Gondwana como diferencialmente al basamento mesoproterozoico del terreno acrecionado de Cuyania, ubicado al oeste. Hacia el este de la Sierra de San Luis, la Sierra de Córdoba ya no fue directamente involucrada en el eje orogénico famatiniano, por lo cual en ella se preservan

En la pegmatita berilífera Santa Ana, localizada en el grupo Cerro La Torre, este fosfato se desarrolla, junto con eosforita, como pequeños cristales euhedrales prismáticos adosados sobre superficies de exfoliación de sicklerita, y deriva de la alteración hidrotermal de litiofilita primaria. En la pegmatita berilífera Ranquel, perteneciente al grupo Loma Alta, huréaulita se encuentra asociada con ferrisicklerita, purpurita, fosfosiderita, strengita, reddingita, meta-autunita, eosforita, vivianita e hidroxil-apatita, y ha sido formada por retrabajado hidrotermal de trifilita; los cristales son idiomorfos, tienen 5 mm de longitud y exhiben típicas formas monoclínicas. En la pegmatita litífera San Luis II, del grupo Paso del Rey, huréaulita forma cristales prismáticos cortos o delgadas costras rosadas intercrecidas entre fibras de dufrénita y en asociación con ferrisicklerita, bermanita y carbonato-fluorapatita, su génesis es atribuida a extrema alteración hidrotermal de litiofilita. En las diferentes yacencias estudiadas, huréaulita muestra similares características físicas y ópticas, pero distintos contenidos en Fe-Mg-Ca como sustituciones octaédricas, en relación con la secuencia de fosfatos secundarios con los que se asocia.

    Full Text Available AIM: The purpose of this work was to determine genera diversity, structural attributes and distribution of the Hydrachnidia assemblages and their possible influences with certain abiotic parameters along the sub-basin of the Grande River, a 6th order stream in the province of San Luis; METHODS: four sampling sites (C1, E1, E2 and E3 were established in two different hydrological periods: high waters (HW and low waters (LW. Twenty-four samples were obtained using Surber sampler, and the hydraulic, physical and chemical characterization of the sampling sites was carried out. Density (ind.m-2, genus richness, Shannon-Wiener diversity index and Kownacki's dominance index were calculated; RESULTS: sixteen Hydrachnidia genera were observed. No significant differences were found between the abiotic parameters of each site. A positive correlation of Sperchon, Torrentícola and Neoatractides was observed in relation to flow and current velocity whereas Hygrobates showed a negative correlation. No significant differences were observed in Hydrachnidia abundances among the sites in HW and LW and between the pairs of each site in HW and LW. The genera with the highest densities were Hygrobates, Limnesia and Atractides, of which the first two were widely distributed. The rest only appeared sporadically. According to Kownacki's index Hygrobates and Limnesia were "dominant", Atractides were "subdominant" and the rest were "non dominant"; CONCLUSIONS: The found genera were distanced systematically and philogenetically. However, the specimens belonging to these genera exhibited very similar morphological characteristics, which were adaptations to rheophilous habitats. The representativity of Hygrobates and Limnesia might be due to the great abundance of their hosts and preys in the sub-basin. The decrease in the densities and the changes in the Hydrachnidia composition in E3 (post-dam site might be explained by the biotic interactions previously mentioned

La información se obtuvo mediante el relevamiento de 15 perfiles sedimentológicos de detalle que permitieron definir 21 facies sedimentarias y 12 asociaciones de facies. Las facies permitieron interpretar los principales procesos de acumulación sedimentaria, mientras que a partir de las asociaciones de facies se propusieron los modelos paleoambientales. Los depósitos cretácicos se han acumulado en sistemas de abanico aluvial, lóbulos fluviales efímeros, planicies fangosas y barreales, dunas eólicas y ambientes lacustres hidrológicamente cerrados. El registro de la sierra de las Quijadas representa a los depósitos clásticos del margen activo de una cuenca extensional con geometría de hemigraben, desarrollada en un marco paleoclimático árido a semiárido. En él se reconocen dos secuencias deposicionales limitadas por sendas discordancias. Cada una de estas secuencias se compone de una fase de sinrift y otra de postrift. En las fases iniciales o de sinrift las asociaciones de facies reflejan pendientes fuertes, ascenso tectónico de las áreas de aporte ubicadas hacia el oeste (Alto del Desaguadero y subsidencia mecánica en la cuenca. Las fases de postrift se caracterizan por depósitos efímeros de bajo gradiente y lacustres que responden a una alta tasa de acomodación y tendencia al ascenso del nivel de base geomorfológico que se vinculan con una etapa dominada por subsidencia termal generalizada.The Cretaceous continental deposits of the El Gigante Group in the northwest of San Luis Province (Sierra de las Quijadas, consist of proximal to distal alluvial fan - ephemeral fluvial, playa and lacustrine systems.

Estas estructuras secundarias se desarrollaron en un ambiente extensional frágil - dúctil a frágil y en un regimen transpresivo, durante un esfuerzo máximo principal s1 NO - SE y el alzamiento de la región. Las características halladas sugieren que el magmatismo famatiniano sinorogénico a posorogénico, ocasionó anomalías térmicas que propiciaron la circulación hidrotermal en sistemas convectivos. El flujo acuoso se encauzó principalmente, por la estructura de primer orden Tres Árboles y lineamientos secundarios. No se encontraron evidencias de que el magmatismo granítico hubiera contribuido significativamente con el aporte de azufre y elementos metálicos, al menos en este estilo de depósitos con marcado control estructural.

    Full Text Available En este trabajo abordamos las prácticas de rechazo y las situaciones de interacción fallida como clave para comprender la metamorfosis de la dominación entre clases en las sociedades latinoamericanas contemporáneas, centrándonos en sectores que han sido expulsados hacia los bordes materiales y simbólicos del capitalismo. Para analizarlas, nos remitimos en clave metonímica a las experiencias de un colectivo de recolectores de residuos y un grupo de receptores de asistencia en dos ciudades de Córdoba y San Luis (Argentina. Desde una Sociología del Cuerpo y de las Emociones, se analizan materiales empíricos de entrevista para identificar las percepciones y emociones de los sujetos en el cruce entre estados corporales y experiencias en la ciudad. Como cierre interpretativo, damos cuenta de los límites que vivencian, materializados en situaciones de distanciamiento y escisión interaccional que describimos como “denegación social”.

    Full Text Available Este trabajo presenta los resultados de una investigación educativa en la materia de Patrimonio Documental impartida en la Escuela de Ciencias de la Información de la Universidad Autónoma de San Luis Potosí. Para la investigación, se siguieron tres momentos. En la primera etapa se investigaron los resultados del uso de las herramientas didácticas como los mapas conceptuales, los estudios de caso y los problemas, entre otros. En la segunda se aplicó un cuestionario sobre el aprendizaje de la asignatura para determinar los temas de interés o los que fueron complicados para estudiantes, y que requirieron de reforzamiento o mayor profundización. En la tercera se elaboró una rúbrica que establece un parámetro de los posibles resultados finales del aprendizaje del grupo. Lo más importante de la aplicación fue la identificación puntual de las barreras de aprendizaje y la realización de acciones para que el alumnado se apropiara del conocimiento. Las partes fuertes del curso se relacionaron con las áreas directamente correspondientes a las Ciencias de la Información Documental y la historia. La parte más débil es la tasación o asignación del valor económico de los bienes bibliográficos y documentales, en virtud de que esta se consolida con un amplio conocimiento del mercado y con la experiencia.

    Full Text Available En los cuerpos máficos-ultramáficos del área de Virorco y La Bolsa, bloque central de la sierra de San Luis, se han detectado sulfuros polimetálicos en venillas y diseminados. Como herramienta de prospección geofísica se utilizó el método de autopotencial en combinación con estudios geomagnéticos. Los lentes máfico-ultramáficos están enmarcados por una caja gnéisicamigmatítica de alto grado. Una foliación milonítica de rumbo NNE y buzamiento de alto ángulo al ESE, afecta al basamento y también a los bordes de los cuerpos máfico-ultramáficos. Hacia el interior de estos últimos, alternan sectores que preservan las texturas granulares ígneas y una foliación buzante al oeste, con fajas de cizalla con foliación milonítica buzante al ESE. El estudio geofísico en Virorco indica una correspondencia entre los valores de autopotencial negativos (-150 mV y los máximos de magnetismo terrestre (+350 nT. En la zona de La Bolsa se realizaron dos perfiles de autopotencial, los cuales muestran un núcleo de autopotencial negativo de entre -40 y -55 mV, ligeramente alargado y buzante al ESE. Sobre el margen oriental, un valor de -90 mV constituye el núcleo de una anomalía alargada y también buzante al ESE. La disposición espacial de estas anomalías es coincidente con la orientación de la foliación milonítica. La correspondencia establecida con esta nueva herramienta de prospección, sustenta la removilización y concentración de los sulfuros primarios diseminados durante el evento de milonitización, ya planteada previamente en base a otras técnicas de estudio.

    Full Text Available Los granitoides de arco pre-deformacionales de San Luis son asignados al Cámbrico tardío-Ordovícico temprano, y conforman una serie de extensos afloramientos en el cordón de El Realito y en la zona norte del plutón La Escalerilla. El magmatismo es calcoalcalino de alto K y se aloja en metasedimentitas regionales de grado bajo a medio. Está representado por una secuencia de arco más antigua, constituida por granodioritas, tonalitas y dioritas con Pl+Bt+Ep±Hbl±Kf, metaluminosas, portadoras de enclaves gábricos y monzodioríticos, correlacionable con la secuencia metaluminosa de las sierras de Chepes y Los Llanos (La Rioja. La serie más joven es colisional, monzogranítica, leucocrática y peraluminosa, con Kf+Pl+Ms±Bt±Grt, de características afines a las de los monzogranitos y leucogranitos de dos micas, y una tendencia evolutiva propia de los granitoides peraluminosos félsicos. La serie monzogranítica no parece resultar del fraccionamiento extremo de la secuencia metaluminosa sino que derivaría de la fusión por deshidratación de metapelitas muscovíticas y grauvacas, aunque algunas particularidades geoquímicas de La Escalerilla, entre ellas la abundancia y evolución de las HREE, podrían atribuirse a diferencias litológicas en la zona de proveniencia del fundido. Los fundidos se distinguen claramente, en ambos casos, de aquéllos que dieron origen a las leucogranodioritas sincinemáticas débilmente peraluminosas que afloran en el complejo basamento oriental de la sierra, portadoras de la misma asociación mineral. La deformación famatiniana modificó las fábricas y en menor proporción el quimismo de ambas secuencias, en particular los términos más básicos de la serie de arco, incrementando su peraluminosidad y la dispersión de las tendencias evolutivas.The pre-deformational Late Cambrian to Early Ordovician arc-magmatism of the Sierra de San Luis forms several outcrops of which Cordón de El Realito and La

The building has a total constructed surface of 27,400 m2 on 15 floors. The top 12 floors are destined for administrative use with work space for about 1,200 employees and the first three floors are reserved for entrance and reception areas, exhibition room, executive offices and indoor garden areas. This unique utilization of the space is clearly evident in the distinct type of planning adopted. A very interesting characteristic of this building, a requisite from the very beginning, is its high degree of organizational flexibility, achieved by using reticular forging of modules of 1.50 x 1.50 m in which the building's different installations are located, which provides service availability anywhere in the building, independent of the organization or departmental divisions adopted.

Esta diferente utilización queda claramente patentizada en el distinto planteamiento formal de plantas y alzados. Una interesante característica de la construcción, exigida en el programa inicial, es el alto grado de flexibilidad organizativa, conferida por el empleo de un forjado reticular, de 1,50 x 1,50 m de módulo, en el que van incluidas las distintas instalaciones del edificio, lo que permite el suministro de servicios a cualquier punto de la superficie, independientemente de la ordenación o compartimentación adoptada.

    A Mining Feasibility Study in the Area of Alto San Jorge, Department of Cordoba, Colombia, was commissioned by CARBOCOL S.A. to the Consortium Geominas-NACI. An area of 800 Ka2 was explored to define surface mining possibilities within two subareas referred to as Alto San Jorge and San Pedro Ure. Rocks of Cretaceous, Tertiary and Quaternary age crop out in the zone. In the subarea Alto San Jorge the principal structure is a syncline with a south-north direction. The San Pedro Ure subarea is formed by undulations with flanks of low dip, the most important being the San Antonio Syncline because it contains the mining block. The geological study of the surface demonstrated the existence of coal in the Oligocene Cienaga de Oro Formation and the Niocene Cerrito Formation, with potential resources of 6.3 billion tons. The subsequent exploration of the subsoil, with 20.618 m of drilling, permitted determination of demonstrated reserves in the order of 2.9 billion tons within two areas. In the sector selected for the mine plan, in the area of San Pedro-Puerto Libertador, 7.791 m of drilling was accomplished to define a demonstrated reserve of 515 million tons of coal down to a depth of 200. The combustible type coal has 5.000 cal/g. Complete mining schedules were developed at the prefeasibility level for two surface mines with productions of 1.5 MMTY and 4 MMTY. 9 figs., 3 tabs., 28 refs.

    Science.gov (United States)

    1985-02-01

    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

    Luis Alvarez was the most remarkable physicist I have ever worked with. As a member of his bubble chamber group at the Lawrence Radiation Laboratory in Berkeley and subsequently as a leader of that group for several years, I could appreciate his outstanding attributes as a physicist and his forceful and colorful personality. Each day at the lab seemed exciting. Although he created the largest research group in particle physics in the world at the time, Luis was an ardent foe of group-think, which he characterized as ``intellectual phase-lock''. He had an uncanny intuition about physics and technology, coupled with an insatiable curiosity about the world around him. He is justly renowned as a member of the Inventors Hall of Fame for his myriad inventions and as a Nobel Laureate in physics for his contributions to particle physics through his development of the hydrogen bubble chamber technique, leading to the discovery of a large number of resonance states. However, it was his wide-ranging curiosity which led him to one of his finest achievements, while working with his son Walter - developing the asteroid impact theory as the explanation of the extinction of the dinosaurs. I will offer some personal recollections of Luis and the group in this period, including some of his other intriguing efforts which illustrate the breadth of his interests, pertaining to the Kennedy assassination and x-raying the pyramids, among them. All in all, a brilliant and most unusual scientist and stimulating colleague.

  7. Effect of Mining Activities in Biotic Communities of Villa de la Paz, San Luis Potosi, Mexico

    Guillermo Espinosa-Reyes

    2014-01-01

    Full Text Available Mining is one of the most important industrial activities worldwide. During its different stages numerous impacts are generated to the environment. The activities in the region have generated a great amount of mining residues, which have caused severe pollution and health effects in both human population and biotic components. The aim of this paper was to assess the impact of mining activities on biotic communities within the district of Villa de la Paz. The results showed that the concentrations of As and Pb in soil were higher than the national regulations for urban or agricultural areas. The bioavailability of these metals was certified by the presence of them in the roots of species of plants and in kidneys and livers of wild rodents. In regard to the community analysis, the sites that were located close to the mining district of Villa de la Paz registered a lower biological diversity, in both plants and wild rodents, aside from showing a change in the species composition of plant communities. The results of this study are evidence of the impact of mining on biotic communities, and the need to take into account the wildlife in the assessment of contaminated sites.

    Directory of Open Access Journals (Sweden)

    Cecilia S.M. Lucero Estrada

    2013-12-01

    Full Text Available An increase in the consumption of fruit juices and minimally processed fruits salads has been observed in recent years all over the world. In this work, the microbiological quality of artisan fruit salads was analysed. Faecal coliforms, Salmonella spp, Shigella spp, Yersinia enterocolitica and Escherichia coli O157:H7 were not detected; nevertheless, eleven strains of Staphylococcus aureus were isolated. By multiplex PCR, all isolates showed positive results for S. aureus 16S rRNA gene and 63.6% of them were positive for sea gene. Furthermore, PCR sea positive strains were able to produce the corresponding enterotoxin. Finally, the inactivation of these strains in fruit salads by nisin, lysozyme and EDTA, was studied. EDTA produced a total S. aureus growth inhibition after 60 h of incubation at a concentration of 250 mg/L. The presence of S. aureus might indicate inadequate hygiene conditions during salad elaboration; however, the enterotoxigenicity of the strains isolated in this study, highlights the risk of consumers' intoxication. EDTA could be used to inhibit the growth of S. aureus in artisan fruit salads and extend the shelf life of these products.

    Full Text Available RESUMEN: La figura de José Luis Hidalgo (Torres, 1919-Madrid, 1947, poeta y pintor, ha de tomar un nuevo relieve como representante de una generación de autores montañeses que surgió en torno a los años cuarenta. Destaca en su breve obra, al igual que su corta pero intensa vida, la extrema sensibilidad de su poesía en el uso de imágenes, metáforas que acercan sus versos hacia el terreno de lo plástico y sensorial. Las preocupaciones son de profunda raigambre existencialista, al ser nuestro poeta un joven lector de pensadores como Nietzsche, Schopenhauer o Unamuno; es con este último con el que guarda una ineludible afinidad de ideas. La búsqueda que emprende José Luis Hidalgo hacia la verdad se sitúa dentro de una metafísica trascendente y una vertiente religiosa muy significativa, en un diálogo sincero y directo con Dios. Contrasta la sencillez formal de su poesía con el complejo sistema simbólico de elementos naturales, espacios... en los que se mueve dentro del marco fluctuante entre la tradición y la vanguardia; encontramos resonancias que nos llevan desde el romanticismo becqueriano, pasando por el simbolismo, hasta los movimientos vanguardistas —sobre todo el surrealismo— y el grupo poético del 27. La obra de Los muertos supone un momento culmen del dilatado periodo de posguerra.ABSTRACT: The literary figure of José Luis Hidalgo (Torres, 1919-Madrid, 1947, both a poet and a painter, achieves renown once more as a representative of a generation of writers from Cantabria (in the north of Spain which came to light around the 1940's. His work, as brief as his short but intense life, is remarkable for the great feeling of his poetry in the use of imagery and metaphors, which draw his verse near the domain of the vivid and sensorial. His concerns have deep existentialist roots; as a young man the poet was a devoted reader of great thinkers such as Nietzsche, Schopenhauer or Unamuno; it is the latter with whom he has an

    Full Text Available By comparison with the historiography of other European and Anglo-Saxon countries, the study of the origins and spread of Eugenics in Spain has not received much attention. Even less research has been done on the degree of acceptance of eugenic thought in the pedagogical domain or on the role teachers may have in the diffusion of eugenics. This paper attempts to explore the subject while focusing the analysis on the relations that were established among Medicine, Pedagogy and Eugenics in Spain during the first third of the 20th century. We will take as a point of reference and guiding line of thought the figure of the Asturian teacher Luis Huerta Naves, who was the driving force and tireless advocate of the eugenics movement in our country.

    Full Text Available Emma Zunz, by Jorge Luis Borges, is the story of a girl who decides to kill her boss in order to avenge her father’s death, believing that her father’s version of an event that occurred years before was true. Thus, she devises a secret plan, which includes losing her virginity to a complete stranger, shortly before committing the crime, so she could argue that her boss had raped her and that she killed him in self-defense. Firstly, the text shows the contrast between formal justice and taking justice into own hands. Secondly, the question of self-inflicted punishment, which in the story takes place before the perpetration of the crime. Finally, the issue whether truth is the version that can be inferred from the evidence presented in a trial, or the one which is kept to themselves by those involved in a crime. Emma Zunz, de Jorge Luis Borges, es la historia de una chica que decide matar a su jefe para vengar la muerte de su padre, creyendo que la versión de su padre de un hecho que ocurrió años atrás era cierta. De este modo, diseña un plan secreto, que incluye la pérdida de su virginidad con un desconocido, poco antes de cometer el crimen, para poder argumentar que su jefe la había violado y que ella lo mató en defensa propia. En primer lugar, el texto muestra el contraste entre la justicia formal y la justicia por cuenta propia. En segundo lugar, la cuestión de la pena infligida a uno mismo, lo que en la historia se produce antes de la comisión del delito. Por último, la cuestión de si la verdad es la versión que se puede inferir de las pruebas presentadas en un juicio, o la que se guardan para sí mismas las personas involucradas en un crimen.

    Full Text Available The article looks at Luis Fayad’s novel La caída de los puntos cardinales (2000 in order to foreground the influence of Arabic on the Colom- bian author whose grandparents were Lebanese. Born in Bogotá in 1945, Fayad published the novel after being identified as one of the first Colombian novelists dealing with urban literature. It represents a change of direction in his career, as Fayad narrates the entire life of six main characters, four men and two women, who decide to leave Lebanon and migrate to South America, ending up in Colombia. The analysis will focus on the importance of the circulation of the book in Italy by virtue of issues of intercultural exchange embedded in the novel. La caída de los puntos cardinales mixes Arabic tradition and Colombian customs; in the novel, Fayad achieves a cross-cultural story that may provide a successful model of integration. The Spanish-Italian translation and a critical approach to the language used by the novelist and employed by the translator will complete the essay.

    La organización es considerada como elemento estratégico en el desarrollo de una localidad rural, ya que a través de ésta se obtienen mayores beneficios, permite a las personas desarrollar sus capacidades y son impulsoras de proyectos dentro de las comunidades. Sin embargo, es común que los territorios rurales cuenten con un tejido asociativo desarticulado que limita esas posibilidades.

    Full Text Available La secuencia metamórfica de alta temperatura y baja presión presente en la sierra de Socoscora está compuesta por esquistos con porfroblastos de cordierita y andalucita, esquistos con nódulos de sericita, esquistos cuarzo biotítico muscovíticos y anfibolitas. Todas estas rocas se encuentran en contacto tectónico con migmatitas y granitoides. Los aforamientos de esta secuencia esquistosa son saltuarios, van de unos pocos metros a algunos kilómetros cuadrados y, en algunos casos, se presentan como xenolitos en los granitoides. Esta secuencia metasedimentaria, con intercalaciones de metabasitas, presenta evidencias de al menos tres fases deformacionales (F1, F2 y F3, asociadas a una evolución metamórfica de baja presión. F1 se desarrolla conjuntamente con un metamorfismo M1 (Bt1 + Ms1, posteriormente crece cordierita estática, entre las fases F1 y F2, dando lugar a M2 (Crd + Bt2 + Qtz + Kfs, durante la fase F2 se alcanza el clímax térmico con la presencia de sillimanita (fibrolita (M3: Bt3+ Ms2 + Sil. Posteriormente, el crecimiento estático de andalucita, post F2, caracteriza a M4 (And + Ms3. Por último, durante F3 se produce el clivaje de crenulación S3. La presencia de abundantes rocas máficas y/o granitoides en la zona, podrían ser responsables de los altos gradientes que permitieron el desarrollo de las paragénesis descriptas. En otros sectores de Sierras Pampeanas se han reconocido rocas formadas en condiciones similares, asociadas a procesos asignados a las orogenias Pampeana y Famatiniana. La falta de datos geocronológicos no permite asignar con precisión las rocas estudiadas a una u otra etapa. Las rocas que se describen en este trabajo podrían corresponder a niveles de menor profundidad que los correspondientes a las migmatitas presentes en la región.The low-pressure high-temperature metamorphic sequence recognized in the Sierra de Socoscora is formed by schists with cordierite and andalusite porphyroblasts, schists with sericite nodules, muscovitic-biotite-quartz schists and amphibolites, in tectonic contact with migmatites and granitoids. The outcrops of this sequence are discontinuous, ranging from a few meters to several square kilometers; in some cases occur as xenoliths within the granitoids. This metasedimentary sequence which is inter-bedded with metabasites provides evidence of at least three deformational phases (F1, F2 y F3 together with a low pressure metamorphic evolution. F1 is developed jointly with a M1 metamorphism (Bt1 + Ms1, static cordierite grows subsequently between the F1 and F2 phases resulting in M2 (Crd + Bt2 + Qtz + Kfs, the thermal climax is reached during the F2 phase with the presence of sillimanite (fibrolite, giving way to M3 (Bt3 + Ms2 + Sil. Subsequently, the growth of static andalusite post F2 generates M4 (And + Ms3. Finally, F3 produced crenulation cleavage (S3. The abundance of mafic rocks and/or granitoids in the zone could be responsible for the high gradients which allowed for the development of the characterized paragenesis. In other sectors of the Sierras Pampeanas, rocks formed under similar conditions have been reported, associated with processes assigned to the Pampean and Famatinian orogenies. The lack of geochronological data hinders the accurate assignment to a particular stage. The rocks described in this work could correspond to shallower levels than those representing the migmatites in the region.

La gruta de Intihuasi es uno de los pocos sitios ubicados fuera del ámbito andino que contiene obsidiana y se encuentra a más de 300 km de las fuentes más cercanas. En el Missouri University Research Reactor se aplicó fluorescencia de rayos X a 11 artefactos de obsidiana excavados en Intihuasi. Se determinó la presencia de 5 grupos distintos, un número elevado comparado con otros sitios de cazadores-recolectores. Los resultados se compararon con la base de datos del MURR. La elevada cantidad de fuentes presentes en Intihuasi sugiere relaciones con grupos de varias regiones, posiblemente del sur cuyano y/o Neuquén. Finalmente, se hacen algunas consideraciones sobre el significado de las interacciones a larga distancia¹.Recent research in the Andes indicates that obsidian was procured and distributed over long distances since the Late Pleistocene and until the Spanish conquest. In this research we used XRF at the Missouri University Research Reactor to determine the number of sources present in a collection of Intihuasi cave obsidian, and its potential provenience. Intihuasi is one of the archaeological sites with obsidian that is outside of the Andean area, and at least 300 km from the nearest source. These materials are at the Museo de Antropología of the Universidad Nacional de Córdoba. The location of one of these sources is northern Neuquén. They are made some suggestions in relation to long distance interactions.

    To investigate the mechanism for diel (24h) changes commonly observed at fixed sampling locations and how these diel changes relate to downstream transport in hypereutrophic surface waters, we studied a parcel of agricultural drainage water as it traveled for 84h in a concrete-lined channel having no additional water inputs or outputs. Algal fluorescence, dissolved oxygen, temperature, pH, conductivity, and turbidity were measured every 30min. Grab samples were collected every 2h for water quality analyses, including nutrients, suspended sediment, and chlorophyll/pheophytin. Strong diel patterns were observed for dissolved oxygen, pH, and temperature within the parcel of water. In contrast, algal pigments and nitrate did not exhibit diel patterns within the parcel of water, but did exhibit strong diel patterns for samples collected at a fixed sampling location. The diel patterns observed at fixed sampling locations for these constituents can be attributed to algal growth during the day and downstream transport (washout) of algae at night. Algal pigments showed a rapid daytime increase during the first 48h followed by a general decrease for the remainder of the study, possibly due to sedimentation and photobleaching. Algal growth (primarily diatoms) was apparent each day during the study, as measured by increasing dissolved oxygen concentrations, despite low phosphate concentrations (<0.01mgL-1). ?? 2011 Elsevier B.V.

  9. Advancements in understanding the aeromagnetic expressions of basin-margin faults—An example from San Luis Basin, Colorado

    Grauch, V. J.; Bedrosian, Paul A.; Drenth, Benjamin J.

    2013-01-01

    Advancements in aeromagnetic acquisition technology over the past few decades have led to greater resolution of shallow geologic sources with low magnetization, such as intrasedimentary faults and paleochannels. Detection and mapping of intrasedimentary faults in particular can be important for understanding the overall structural setting of an area, even if exploration targets are much deeper. Aeromagnetic methods are especially useful for mapping structures in mountain-piedmont areas at the margins of structural basins, where mineral exploration and seismic-hazard studies may be focused, and where logistical or data-quality issues encumber seismic methods. Understanding if the sources of aeromagnetic anomalies in this context originate from sedimentary units or bedrock is important for evaluating basin structure and/or depth to shallow exploration targets.

  19. The parody in Death and the Compass by Jorge Luis Borges as a Metaphysical Detective Novel

    The emergence of metaphysical detective novels changed the situation that traditional detective novels are often criticized as vulgar literature for its escaping from reality and its purpose of recreation and stimulus. Jorge Luis Borges is one of the forerunners of metaphysical detective fiction. Especially, some of his short novels become the classics of metaphysical detective novels. In this thesis, I will try to analyze the parody of one of Jorge Luis Borges’ representative metaphysical detective novels -“Death and the Compass” to see the main differences between metaphysical detective novels and traditional detective novels. This thesis is divided into three parts. Chapter one gives brief introduction about traditional detective novels. Chapter two discusses the parody in this novel. And chapter three comes to the conclusion which gives the reason for this change.

  3. SANS studies of polymers

    International Nuclear Information System (INIS)

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H2O/D2O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    San Jose, capital city of Costa Rica, fills the valley between two steep mountain ranges. In this image made from data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite, visible, shortwave, and near-infrared wavelengths of light that the sensor observed have been combined to produce a false-color version of the scene in which vegetation is red, urban areas are silvery gray, water is dark blue, and clouds are white. The image was captured on February 8, 2007. San Jose is in the center of the image. The Rio Torres winds through downtown San Jose. Cartago, the much smaller colonial capital, sits in the lower right corner, while the city of Alajuela appears across the river, northwest of San Jose. The cities' manmade surfaces contrast sharply with the lushly vegetated landscape surrounding the city. Greenhouses are common in the region, and their glass roofs may be the brilliant white spots around the outer edges the cities. The long, straight runway of the Tobias Bolanos International Airport is visible as a dark line southeast of Alajuela. The landscape around the two cities shown here is rugged. Steep mountain peaks cast dark shadows across their leeward slopes. Patches of dark red vegetation on the mountains north of San Jose may be rainforest. Coffee plantations also cover the slopes of the mountains around the city. February is the dry season in Costa Rica. During the rainy season, from about April to November, clouds usually block the satellite's view of this tropical location.

  7. LUIS SEPÚLVEDA: UN VIAJE EXPRESS AL CORAZÓN DE LA PATAGONIA Luis Sepúlveda: an express travel to Patagonia’s heart

    Full Text Available En este artículo se analizan las formas de representación de la Patagonia en la novela Patagonia Express de Luis Sepúlveda. Con mucho de intertextualidad y algo de novela sentimental, los relatos de viaje del escritor chileno en los que aparece la Patagonia están armados como narraciones por espacios de la imaginación destinados a seducir al lector para instalarlo en un espacio misterioso, mitad legendario, mitad histórico, trazando un recorrido apasionado con el que logra un vínculo empático muy fuerte con el lector. Nuestra hipótesis es que el de Patagonia Express no es un espacio aferrado al referente sino que lo que interesa es re-visitar y revitalizar una matriz legendaria y textual ya existente sobre la Patagonia. Por ese apego a lo construido literariamente, al describir el referente, el relato se deja influir por los estereotipos del texto fundador.This article will analyze forms of representation of the Patagonia in the novel Patagonia Express by the Chilean author Luis Sepulveda. Characterized by intertextuality as well as aspects of the sentimental novel, these travel tales of the Patagonia are structured as narratives by spaces of the imagination. These spaces are designed to seduce the reader, installing him in a mysterious space, both legendary and historical; whose passionate exploration will create a strong bond between text and reader. Our hypothesis is that the Patagonia of Patagonia Express is not a space established by its referent; rather, the emphasis is upon revisiting and revitalizing originative legends and texts. Because of this attachment to literary constructions, descriptions of the referent allow the reader to be influenced by stereotypes of the foundational text.

    Full Text Available Resumen: Este artículo ofrece un estudio del manuscrito autógrafo de la comedia, El satisfecho, firmado por el dramaturgo Luis Belmonte en Sevilla, el 24 de Julio de 1634. El documento proporciona buena información acerca de su recorrido por el tiempo, desde que obtiene la licencia de representación en Lisboa, en 1639, hasta que aparece en Toro, en 1653, como propiedad de Santiago Manteca. El manuscrito resulta muy interesante por la gran cantidad de probationes pennae, de contenido variado y ajeno al asunto teatral, que contiene. Estos ejercicios de escritura, salidos todos ellos de la pluma de Santiago Manteca, revelan que el escribano es un hombre preocupado por el mundo documental y formulístico. Su poco interés por conservar limpio el documento indica, por un lado, que , tal vez, la comedia ya no tenía éxito y, por otro lado, la más que probable desconexión de Manteca del mundo teatral. Abstract: This article studies an autographic manuscript of the comedy, El satisfecho, signed by the playwright Luis Belmonte in Seville, on July 24 1634. The document provides sound information about its journey through time, from the moment when it obtained its representation permit in Lisbon, in 1639, until it appeared in Toro, property of Santiago Manteca. The interest of the manuscript is very high due to the great number of probationes pennae that it contains, of very varied content and unrelated to the world of theatre. These writing exercises, coming out of Santiago Mantecas pen, reveal that the secretary was a man concerned about the documental and formulaic world. His lack of interest in keeping the document clean may indicate, on the one hand, that the comedy was not successful any more, and, on the other, Mantecas likely disconnection from the theatrical world.

    Portuguese wall tiles from centuries, XVII, XVIII and XIX, found in Sao Luis Maranhao has been studied by X-ray diffraction, in order to interpret the possible raw material and burning temperature. The mineral phases, Quartz, Wollastonite, Calcite and Gehlenite were identified in all samples. Based on the results it is possible to affirm that the main raw materials used to manufacture this materials was probably mixtures of kaolinite clay and calcite. Based on the mineralogical information it was also possible to state that burning temperature of this wall tiles was lower than 1000 deg C. (author)

    In the process of passing on and carrying forward the culture, some words have loaded the culture. In this article, the author analyzes the translations of the culture-loaded words, especially the words embodying the religious culture in the Gospel According to Mark (by Jorge Luis Borges) on the basis of Nida’s five types of cultures. Comparing the Chinese version translated by Wang Yongnian and the English one translated by Norrnan Thomas di Giovanni in collaboration with Jorge Luis Borges, the author puts forwards that means of translation should be flexible to achieve the goal of cross-cultural communications.

    Full Text Available The paper contrasts the two forms in which the psychiatrist and writer Luis Martin-Santos considered the meaning of illness: the psychiatric and the literary one. The psychiatric approach was a very orthodox one within the phenomenological and existencialist trends, that were prevailing in Spanish psychiatry at that time. Nevertheless, the literary approach was, to a large extent, a bitter and sarcastic criticism of that procedure of considering illness.

    El trabajo confronta las dos formas en que el psiquiatra y médico Luis Martín-Santos consideró la cuestión del significado de la enfermedad: la psiquiátrica y la literaria. El abordaje psiquiátrico se atuvo de manera bastante ortodoxa a las concepciones fenomenológicas y existenciales dominantes en la psiquiatría española del momento. Por contra, el acercamiento literario fue, en gran medida, una crítica ácida y sarcástica de aquella manera de pensar la enfermedad.

    Full Text Available En contraste con lo observable en la historiografía de otros países europeos y anglosajones, el estudio de la introducción y difusión de los principios y prácticas de la Eugenesia, como tema de investigación, no ha contado en España con muchos cultivadores. Menos todavía han sido objeto de estudio las relaciones del pensamiento eugénico con el ámbito pedagógico para indagar la recepción que tiene entre el Magisterio, y conocer el conjunto de reacciones que provoca, así como la participación de los maestros en la potencial difusión de sus planteamientos. Se aborda aquí una aproximación a ese tema centrando el análisis en las relaciones que en la España del primer tercio del siglo XX se establecen entre Medicina, Pedagogía y Eugenesia. Para ello tomamos como referente e hilo conductor la figura y el pensamiento del maestro asturiano Luis Huerta Naves, decidido impulsor y propagandista incansable de la Eugenesia en nuestro país.By comparison with the historiography of other European and Anglo-Saxon countries, the study of the origins and spread of Eugenics in Spain has not received much attention. Even less research has been done on the degree of acceptance of eugenic thought in the pedagogical domain or on the role teachers may have in the diffusion of eugenics. This paper attempts to explore the subject while focusing the analysis on the relations that were established among Medicine, Pedagogy and Eugenics in Spain during the first third of the 20th century. We will take as a point of reference and guiding line of thought the figure of the Asturian teacher Luis Huerta Naves, who was the driving force and tireless advocate of the eugenics movement in our country.

The authors analyzed the one-year temperature cycle values continuously registered in Poarta lui Ionel Cave by using five data loggers. Pursuant to the distinctive cave morphology, the big gallery that forms the basal level is under a permanent bidirectional ventilation effect, while the upper gallery is characterized by an obvious stability. According to the dynamics of air exchanges, theoutside influences are strong enough, so that to the cave temperature vary during a year period with an evident periodicity, not only seasonal, but also daily. In spite of the lack of a similar periodicity, the daily amplitudes are quite important, exceeding 1°C in the extremity of the basal gallery. These facts mean that, beside the convection phenomena, the outside influences can also propagate in the cave by conduction.

    Full Text Available Aware of television’s high level of persuasion and impact, politicians have progressively adapted their messages to the guidelines of the audiovisual media in order to strongly persuade TV viewers, which are seen as potential voters. Currently, the communication, marketing and telegenicity teams of most political parties do not only train their politicians to effectively use verbal communication, but they also try to reinforce their non-verbal communications skills, because they understand that a really effective message is only created through the correct combination of both dimensions. This article presents an in-depth study of the nonverbal communication displayed by the Prime Minister of Spain, José Luis Rodríguez Zapatero, during the first quarter of 2010 when a political topic predominated in the agenda: the financial crisis. Through content analysis, and a self-developed methodology, the study aims to decipher the strategic meaning of this political leader’s kinesic behaviour in the second edition of Telediario, the news programme broadcast by Spain’s Public TV Network (Televisión Española, aka, TVE.

The nominations for the Nobel Prize for literature in 1979 came together, as in a real literary constellation, Italo Calvino, Alberto Moravia, Giorgio Bassani, Vittorio Sereni, Leonardo Sciascia and Mario Luzi, along with the argentine Jorge Luis Borges. The list reflects the richness and variety of Italian literature of the time. But beyond the storytellers, the coincidence of Luzi and Borges (and we might add, that of Odisseas Elytis, who was finally awarded the prize is a unique convergence of poets, with very different poetics, but with intense communicating vessels that unite them, often invisible and contradictory manner. While Borges never wrote about Luzi, the italian, however, did, and quite often, on the argentine, not only from the pages of literary criticism in «Il Corriere della Sera», space occupied until 1974 commenting Latin American literature (he has written about Roberto Arlt, Vargas Llosa and Juan Rulfo, among other writers, but in different interviews, where the frequent quotations that Luzi makes about Borges often installed a space for discussion and profound differences not only on the nature of poetry, but on the same link with the world and life. We propose to study these reflections that Mario Luzi made from (and on many occasions, against about the Argentine author, from the critical work of the Florentine poet, on the centenary of his birth.

Those first urban plans of the Provincial Council make up a homogeneous set of documents since they respond to a unique style of urban planning that varies as much as the original core of the population does. The common element is the ground plan centrality that would be highlighted by an area or a protected green zone that will somehow link to the urban proposals connected to the city-garden model by Howard. Commencement of which began at a time characterized mainly by the co-existence of a great diversity of laws and percepts, making it so that the meaning of the term urban planning could be applied in a variety of ways.

Tanto José Martí como Manuel Gutiérrez Nájera y otros de los autores emblemáticos del modernismo, han sido escrutados y valorados a lo largo de estos años. Sin embargo, Urbina ha permanecido relegado a las historias de la literatura y a las bibliotecas, lo cual sugiere un casi nulo conocimiento de su obra. En este ensayo se analizan algunos de los textos incluidos en su libro Cuentos vividos y crónicas soñadas, publicado en 1915, para contribuir a la revalorización y difusión de su obra a 150 años de su nacimiento.

    Full Text Available Los debates en torno al Centenario de las independencias latinoamericanas fueron también una reflexión sobre la memoria de lo que se había intentado liberar en 1810 para poder hacer un balance de lo que se había logrado en 1910. En Chile, Luis Emilio Recabarren y Alejandro Venegas apuntaron a la experiencia de la nación, a los liderazgos y logros de esta como dispositivo de paso del Colonialismo a la Modernidad y como fórmula política de emancipación. En este artículo, abordo la afirmación de ambos autores de que se vivía el ocaso del ciclo histórico abierto por la coyuntura independentista a causa del agotamiento de los sueños de comunidad, felicidad y soberanía trazados por sus relatos de liberación. El énfasis puesto por Recabarren en el quiebre del relato nacional de emancipación y por Venegas en el colapso moral de sus liderazgos los llevaba a explorar, amparados en la memoria, las características de lo que concebían como el final de una historia.

    We have investigated the lipid sorting in a binary small unilamellar vesicle (SUV) composed of cone-shaped (1,2-dihexanoyl-sn-glycero-3-phosphocholine: DHPC) and cylinder-shaped (1,2-dipalmitoyl-sn-glycero-3-phosphocholine: DPPC) lipids. In order to reveal the lipid sorting we adopted a contrast matching technique of small angle neutron scattering (SANS), which extracts the distribution of deuterated lipids in the bilayer quantitatively. The SANS profile of deuterated SUVs at the contrast matching condition showed a characteristic scattering profile, indicating an asymmetric distribution of cone-shaped lipids in the bilayer. The fitting of the observed SANS profile revealed that most DHPC molecules are localized in the outer leaflet, which supports that the shape of the lipid is strongly coupled with the membrane curvature. We compared the obtained asymmetric distribution of the cone-shaped lipids in the bilayer with the theoretical prediction based on the curvature energy model. (author)

  3. Marketing San Juan Basin gas

    International Nuclear Information System (INIS)

    Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

  4. Structure of microemulsions by SANS

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has been used to determine the structure of microemulsions in the system hydrocarbon-water-sodium di-ethylhexylsulfosuccinate (AOT). SANS spectra taken in a deuterated solvent showed a perfect Guinier fit with a radius of gyration of 15A regardless of the amount of AOT from 0.1 to 5% present. By varying the proportions of deuterated and undeuterated solvent to vary the contrast between the micelles and the solvent, it is concluded that the micelles are basically monodispersed spherical aggregations of 22 AOT molecules

    The Advanced Spaceborne Thermal Emission and Reflection radiometer, ASTER, is an international project: the instrument was supplied by Japan's Ministry of International Trade and Industry. A joint US/Japan science team developed algorithms for science data products, and is validating instrument performance. With its 14 spectral bands, extremely high spatial resolution, and 15 meter along-track stereo capability, ASTER is the zoom lens of the Terra satellite. The primary mission goals are to characterize the Earth's surface; and to monitor dynamic events and processes that influence habitability at human scales. ASTER's monitoring and mapping capabilities are illustrated by this series of images of the San Francisco area. The visible and near infrared image reveals suspended sediment in the bays, vegetation health, and details of the urban environment. Flying over San Francisco (3.2MB) (high-res (18.3MB)), we see the downtown, and shadows of the large buildings. Past the Golden Gate Bridge and Alcatraz Island, we cross San Pablo Bay and enter Suisun Bay. Turning south, we fly over the Berkeley and Oakland Hills. Large salt evaporation ponds come into view at the south end of San Francisco Bay. We turn northward, and approach San Francisco Airport. Rather than landing and ending our flight, we see this is as only the beginning of a 6 year mission to better understand the habitability of the world on which we live.

  3. Velocity selector for SANS spectrometer

    International Nuclear Information System (INIS)

    Mechanical velocity selector, designed firstly at the beginning of the neutron age (the end of 40-th - 50-th, see and references herein) are nowadays of wide use at SANS spectrometers on steady state neutron sources. The present report is devoted to the description of the construction and parameters of the selector, designed for SANS spectrometer at the 1 MW research reactor (URGN, Draria, Algeria). The design of selector provides high transmission (more then 90%) and wavelength resolution of Δλ,/λ ∼ 14%, allowing the neutron wavelength to be selected between 4 A and 10 A. The rotor of selector is an aluminium cylinder rotating in a vacuum jacket around the horizontal axis. The rotor slits of helical shape are formed by absorbing plates with thickness 0.5 mm and made of Gd (10%)-Al alloy. (author)

  4. Sintered materials studied by SANS

    International Nuclear Information System (INIS)

    Complete text of publication follows. The small angle scattering of compacted and sintered single phase materials with open or closed porosity can be described by the two phase model. During sintering, the decrease of pore volume is accompanied with decreasing internal surface measured by SANS [1]. Such investigation can be extended to the field of technically relevant multiphase materials as well, e.g. doped tunsten, SiN ceramics and WC-Co composite made from nano-crystalline powder. The deformation of remaining porosity after sintering can be monitored by 2D anisotropy of SANS distribution as the sintered body is processed through several steps of thermomechanical treatment. The elongation of pores or stable bubbles, e.g. K gas filled bubbles in doped W [2], follows the macroscopic deformation of the body. Heat treatment, however, causes spheroidization with vanishing SANS anisotropy. Our investigation using the isointensity contour map method allows establishing a new description of mechanisms of thermomechanical processing. (author) [1] O. Blaschko, R. Glas, G. Krexner and P.

    Full Text Available El presente artículo analiza la identidad de Adonis García, protagonista de la novela en estudio, y el discurso de la misma como dos hechos primordiales bajo los que se fundamenta una crítica severa al sistema de género institucionalizado en México. La identidad de Adonis García muestra una triple presencia subversiva por tratarse de un homosexual/prostituto que, además, goza de su trabajo. Por otra parte, esta ruptura con el sistema de género hegemónico no puede realizarse con una argumentación filtrada a través del lenguaje usado por el dispositivo sexual institucionalizado; sino mediante una de-construcción del mismo y de la puesta en práctica de un discurso contra-hegemónico. Estos dos elementos –identidad y discurso– promueven un cuestionamiento a la forma de concebir el sujeto marginado por parte de los mecanismos del poder y, además, son subvertidos por Adonis García para construir, con base en su estatuto “ denigrado ”, una estrategia vital placentera y libertaria.This article analyzes the discourse and identity of Adonis García, the main character in the seminal work of Luis Zapata, El vampiro de la colonia Roma (1979, as two main venues used by its author to express a strong criticism against the institutionalized practice of gender relations in Mexico at the time of the publication of this foundational novel. The identity of Adonis García has a three dimensional subversion in the sense that he is not only openly homosexual, but also a male whore that frankly accepts he enjoys this kind of work. In order to represent this subversion in the hegemonic gender system, Zapata breaks with the official discourse and deconstructs its language, setting in its place a contra hegemonic discourse. Thus, identity and discourse in this novel are interwoven questioning the marginality of a gay man as represented in the official language and subverting its mechanisms of power.

    2010-01-01

    Ever since 1858, when Gaspard-Félix Tournachon (pen name Félix Nadar) took the first aerial photograph (Professional Aerial Photographers Association 2009), the scientific value and popular appeal of such pictures have been widely recognized. Indeed, Nadar patented the idea of using aerial photographs in mapmaking and surveying. Since then, aerial imagery has flourished, eventually making the leap to space and to wavelengths outside the visible range. Yet until recently, the availability of such surveys has been limited to technical organizations with significant resources. Geolocation required extensive time and equipment, and distribution was costly and slow. While these situations still plague older surveys, modern digital photography and lidar systems acquire well-calibrated and easily shared imagery, although expensive, platform-specific software is sometimes still needed to manage and analyze the data. With current consumer-level electronics (cameras and computers) and broadband internet access, acquisition and distribution of large imaging data sets are now possible for virtually anyone. In this paper we demonstrate a simple, low-cost means of obtaining useful aerial imagery by reporting two new, high-resolution, low-cost, color digital photographic surveys of selected portions of the San Andreas fault in California. All pictures are in standard jpeg format. The first set of imagery covers a 92-km-long section of the fault in Kern and San Luis Obispo counties and includes the entire Carrizo Plain. The second covers the region from Lake of the Woods to Cajon Pass in Kern, Los Angeles, and San Bernardino counties (151 km) and includes Lone Pine Canyon soon after the ground was largely denuded by the Sheep Fire of October 2009. The first survey produced a total of 1,454 oblique digital photographs (4,288 x 2,848 pixels, average 6 Mb each) and the second produced 3,762 nadir images from an elevation of approximately 150 m above ground level (AGL) on the

  12. SANS from interpenetrating polymer networks

    International Nuclear Information System (INIS)

    Full text: Interpenetrating polymer networks (IPNs) have been formed by combining two polymeric systems in order to gain enhanced material properties. IPNs are a combination of two or more polymers in network form with one network polymerised and/or crosslinked in the immediate presence of the other(s).1 IPNs allow better blending of two or more crosslinked networks. In this study two sets of IPNs were produced and their microstructure studied using a variety of techniques including small angle neutron scattering (SANS). The first system combined a glassy polymer (polystyrene) with an elastomeric polymer (SBS) with the glassy polymer predominating, to give a high impact plastic. The second set of IPNs contained epichlorohydrin (CO) and nitrile rubber (NBR), and was formed in order to produce novel materials with enhanced chemical and gas barrier properties. In both cases if the phase mixing is optimised the probability of controlled morphologies and synergistic behaviour is increased. The PS/SBS IPNs were prepared using sequential polymerisation. The primary SBS network was thermally crosslinked, then the polystyrene network was polymerised and crosslinked using gamma irradiation to avoid possible thermal degradation of the butadiene segment of the SBS. Tough transparent systems were produced with no apparent thermal degradation of the polybutadiene segments. The epichlorohydrin/nitrile rubber IPNs were formed by simultaneous thermal crosslinking reactions. The epichlorohydrin network was formed using lead based crosslinker, while the nitrile rubber was crosslinked by peroxide methods. The use of two different crosslinking systems was employed in order to achieve independent crosslinking thus resulting in an IPN with minimal grafting between the component networks. SANS, Transmission electron microscopy (TEM), and atomic force microscopy (AFM) were used to examine the size and shape of the phase domains and investigate any variation with crosslinking level and

In 2010, the Municipality of Trieste has embarked on the construction of the Park San Giusto, a futuristic solution for the parking of cars: once completed, it will be the largest park in the cave in Italy and the second in Europe, the cars will be a total of 718 on 5 levels buried beneath the hill of San Giusto , in the historic center of Trieste.

  17. Multibeam focusing in SANS technique

    Energy Technology Data Exchange (ETDEWEB)

    Len, A.; Pepy, G.; Rosta, L

    2004-07-15

    The use of four beams separated by a cross-shaped aluminum plate inside the collimator tube, placed at the exit of the 40x40 mm{sup 2} guide of the Budapest Neutron Center's small-angle neutron scattering (SANS) spectrometer, allowed us to gain a factor close to 4 in neutron intensity. The aluminum separator and the inner surface of the collimator vacuum tube was coated with boron carbide. The cross-section of each beam was 8x8 mm{sup 2} at the sample position. This setting can be used for measuring large, homogeneous samples, when the measurement does not need high spatial resolution. The beams were focused on the detector by appropriate diaphragms, the collimation length and the sample-detector distance were 4700 mm. In a real SANS experiment we have compared measurements performed on tungsten wire samples with and without beam separator. Using this beam multiplicator the measurement time could be reduced to a quarter.

  18. MAPP in action in San Antonio, Texas.

    2005-01-01

    San Antonio was selected as an official Mobilizing for Action through Planning and Partnerships (MAPP) demonstration site by National Association of County and City Officials in 2000. The San Antonio Metropolitan Health District, under the leadership of Dr Fernando A. Guerra, agreed to facilitate the process. The MAPP process provided the San Antonio Metropolitan Health District, the local public health authority, a defined process for community health improvement, as well as a mechanism to help bridge the gap between public health and the community. The San Antonio Metropolitan Health District organized a Core Planning Team to lead the MAPP process in April 2001. By October 2002, the Core Planning Team was expanded to a full community working group named the Alliance for Community Health in San Antonio and Bexar County (Alliance). The Alliance identified six strategic issues, which eventually became the basis of the San Antonio Community Health Improvement Plan. The strategic issues are Public Policy, Data Tracking, Healthy Lifestyles, Promoting a Sense of Community, Access to Care, and Safe Environment. San Antonio's MAPP experience has been successful in bringing together the public health system partners, and establishing public health priorities collectively. The MAPP process has resulted in the development of many new initiatives, and, most important, has opened the door to many partnership opportunities in the future. The work of the Alliance, through the MAPP process, has helped to leverage resources for public health improvement in San Antonio, and has the potential to effect positive change in public health in the future.

    The creation and use of a vertically integrated data base, including LANDSAT data, for local planning purposes in a portion of San Bernardino County, California are described. The project illustrates that a vertically integrated approach can benefit local users, can be used to identify and rectify discrepancies in various data sources, and that the LANDSAT component can be effectively used to identify change, perform initial capability/suitability modeling, update existing data, and refine existing data in a geographic information system. Local analyses were developed which produced data of value to planners in the San Bernardino County Planning Department and the San Bernardino National Forest staff.

  9. Tracing seasonal nitrate sources and loads in the San Joaquin River using nitrogen and oxygen stable isotopes

    Science.gov (United States)

    Young, M. B.; Kendall, C.; Silva, S.; Stringfellow, W. T.; Dahlgren, R. A.

    2007-12-01

    The San Joaquin River (SJR) is a heavily impacted river draining a major agricultural basin in central California. This river receives nitrate inputs from multiple point and non-point sources including agriculture, livestock, waste water treatment plants, septic systems, urban run-off, and natural soil leaching. Nitrate inputs to the SJR may play a significant role in driving algal blooms and reducing overall water quality. The San Joaquin River discharges into the San Francisco Bay-Delta ecosystem, and reduced water quality and large algal blooms in the SJR may play a significant role in driving critically low oxygen levels in the Stockton Deep Water Shipping Channel. Correct identification of the major nitrate sources to the SJR is important for coordinating mitigation efforts throughout the SJR-Delta-San Francisco Bay region. Measurements of the nitrogen and oxygen isotopic composition of nitrate were made monthly to bimonthly from 2005 through 2007 within the Lower SJR, major tributaries, and various other water input sources in order to assess spatial and temporal variations in nitrate inputs and cycling in this heavily impacted watershed. The oxygen and hydrogen isotopic composition of water was also measured to better distinguish water sources and identify changes in water inputs. A very wide range of δ15N-NO3 and δ18O-NO3 values were observed in the main stem SJR and tributaries. The δ15N values ranged from +2 to +17 ‰, and the δ18O values ranged from -1 to +18 ‰. Except for a major agricultural drain site (San Luis Drain), all the sites showed temporal changes in both δ15N-NO3 and δ18O-NO3 much greater than the differences seen between individual sites. In general, the δ15N values of nitrate in the larger tributary rivers (Merced, Tuolumne and Stanislaus) were much lower than those of the main stem SJR from April to May; however, after June the tributary values began to rise toward the values in the main stem river.

    SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

  7. Chronology of eclipse "San Miao"

    2001-06-01

    The ancient book "Mozi" (5th century BC) records: "In ancient times, the San Miao tribes were in disarray. The sun rose in the evening...King Yu vanquished them. "King Yu is a prehistoric person living in 23-19th century BC. The strange phenomena "sun rose in evening" was explained as a large solar eclipse at sunset by Pang. Therefore investigations on it may lead to an important progress of Chinese chronology. After an analysis on all similar records in Chinese history, we pay main attention to the relationship of eclipse computations with parameter "c", the long term of earth's rotation rate. We have computed all the solar eclipses in that period by the way similar to that used for investigating the "double dawn" eclipse. By change parameter "c" in reasonable range (28-36 sec/cy2), we have found 11 possible results listed in a table. One figure shows the eclipse maps and relative "double dawn/dusk" areas while another one illustrates how the parameter "c" affects the result. For an exact conclusion of King Yu's chronology, we need further progress from both side: history which may limit the King Yu's period and astronomy which may limit the possible range of parameter "c".

  14. The San Andreas Fault 'Supersite' (Invited)

    Science.gov (United States)

    Hudnut, K. W.

    2013-12-01

    An expanded and permanent Supersite has been proposed to the Committee on Earth Observation Satellites (CEOS) for the San Andreas Fault system, based upon the successful initial Group on Earth Observations (GEO) Geohazard Supersite for the Los Angeles region from 2009-2013. As justification for the comprehensive San Andreas Supersite, consider the earthquake history of California, in particular the devastating M 7.8 San Francisco earthquake of 1906, which occurred along the San Andreas Fault, as did an earthquake of similar magnitude in 1857 in southern California. Los Angeles was only a small town then, but now the risk exposure has increased for both of California's megacities. Between the San Francisco and Los Angeles urban areas lies a section of the San Andreas Fault known to creep continually, so it has relatively less earthquake hazard. It used to be thought of as capable of stopping earthquakes entering it from either direction. Transitional behavior at either end of the creeping section is known to display a full range of seismic to aseismic slip events and accompanying seismicity and strain transient events. Because the occurrence of creep events is well documented by instrumental networks such as CISN and PBO, the San Andreas Supersite can be expected to be especially effective. A good baseline level of geodetic data regarding past events and strain accumulation and release exists. Many prior publications regarding the occurrence of geophysical phenomena along the San Andreas Fault system mean that in order to make novel contributions, state-of-the-art science will be required within this Supersite region. In more recent years, the 1989 Loma Prieta earthquake struck adjacent to the San Andreas Fault and caused the most damage along the western side of the San Francisco Bay Area. More recently, the concern has focused on the potential for future events along the Hayward Fault along the eastern side of San Francisco Bay. In Southern California, earthquakes

La lírica fue el género más influenciado por la situación que los exiliados estaban experimentando, razón por la que sus textos pueden dividirse en periodos, con diferentes rasgos, dependientes de la situación histórica que experimentaban: Segunda Guerra Mundial, final de la guerra y afianzamiento del Franquismo, etc. Entre los muchos autores exiliados, Luis Cernuda fue uno de los más reconocidos, donde los rasgos de la poética del destierro estaban presentes, de una forma velada, trágica y sucinta, como era propio de toda su producción.

  17. Compact High Resolution SANS using very cold neutrons (VCN-SANS)

    International Nuclear Information System (INIS)

    SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

    Full Text Available El estudio de las Organizaciones No Gubernamentales estuvo dirigido a caracterizar la diversidad de grupos y asociaciones que bajo el termino genérico de ONG’s existen en los municipios Maracaibo y San Francisco, los más poblados y relevantes en la vida política, económica, social y cultural del estado Zulia-Venezuela. Se planteó una investigación exploratoria y descriptiva. El resultado permitió reconocer a Existe un crecimiento sostenido de las ONG en estos municipios: b los sectores con mayor concentración son el de salud; educación; deporte y recreación; arte y cultura. c Las instituciones que promueven más organizaciones son la iglesia y el Estado, lo que supone es este último caso una reducción de las funciones que le corresponden, además de la minimización de costos y conflictos laborales. d Ambivalencia en la orientación de su funcionamiento: Algunas ONG’s implementan prácticas próximas a la mercantilización de los servicios con lo cual legitiman estrategias del modelo económico neoliberal mientras otras contribuyen a fortalecer la democratización de los servicios públicos. Se concluye que el crecimiento y características de las ONGs en estos municipios estuvo vinculado en los noventa y comienzos de la década de 2000 por la aplicación de las políticas públicas neoliberales.

    Serum from endangered San Joaquin kit foxes, Vulpes macrotis mutica, and sympatric wildlife inhabiting the Elk Hills Petroleum Reserve, Kern County, and Elkhorn Plain, San Luis Obispo County, California, was collected in 1981 to 1982 and 1984, and tested for antibodies against 10 infectious disease pathogens. Proportions of kit fox sera containing antibodies against diseases were: canine parvovirus, 100% in 1981 to 1982 and 67% in 1984; infectious canine hepatitis, 6% in 1981 to 1982 and 21% in 1984; canine distemper, 0 in 1981 to 1982 and 14% in 1984; tularemia, 8% in 1981 to 1982 and 31% in 1984; Brucella abortus, 8% in 1981 to 1982 and 3% in 1984; Brucella canis, 14% in 1981 to 1982 and 0 in 1984; toxoplasmosis, 6% in 1981 to 1982; coccidioidomycosis, 3% in 1981 to 1982; and plague and leptospirosis, 0 in 1981 to 1982. High population density, overlapping home ranges, ability to disperse great distances, and infestation by ectoparasites were cited as possible factors in the transmission and maintenance of these diseases in kit fox populations.

  20. A compliance monitoring program for use and operation of the Grasslands Bypass for drainage conveyance in the western San Joaquin Valley

    1995-11-01

    The Bureau of Reclamation (Reclamation) signed a Finding of No Significant Impact (FONSI) No. 92-02-MP dated October 18, 1991 and a Supplement to the FONSI No. 92-03-MP dated April 15, 1991, for use of a 19 mile segment of the San Luis Drain, renamed the Grasslands Bypass, to convey agricultural drainage waters to the San Joaquin River. An Environmental Assessment was prepared and published in support of the FONSI. On September 7, 1995 a Supplemental Environmental Assessment was prepared to update the original document to account for changes to the original project. These changes included a change to the point of entry to the Drain and an increase in the length of the Drain utilized by the Project from 19 to 28 miles. Environmental commitments and a schedule of fees for non-compliance with monthly and annual selenium load targets were also agreed upon for the current Project. Environmental documents preceding the FONSI outlined a monitoring program that obtained general and informal concurrence by technical staff of the participating agencies. A revised version of the proposed monitoring program was distributed by Reclamation for review and comment by the agencies in July 1992. A final monitoring plan document was issued in June 1993 and was subsequently approved by the Oversight Committee. This document includes substantial revisions to the existing June 1993 monitoring plan to reflect the compliance requirements of the current Project.

  1. Technical Analysis of In-Valley Drainage Management Strategies for the Western San Joaquin Valley, California

    Presser, Theresa S.; Schwarzbach, Steven E.

    2008-01-01

    The western San Joaquin Valley is one of the most productive farming areas in the United States, but salt-buildup in soils and shallow groundwater aquifers threatens this area?s productivity. Elevated selenium concentrations in soils and groundwater complicate drainage management and salt disposal. In this document, we evaluate constraints on drainage management and implications of various approaches to management considered in: *the San Luis Drainage Feature Re-Evaluation (SLDFRE) Environmental Impact Statement (EIS) (about 5,000 pages of documentation, including supporting technical reports and appendices); *recent conceptual plans put forward by the San Luis Unit (SLU) contractors (i.e., the SLU Plans) (about 6 pages of documentation); *approaches recommended by the San Joaquin Valley Drainage Program (SJVDP) (1990a); and *other U.S. Geological Survey (USGS) models and analysis relevant to the western San Joaquin Valley. The alternatives developed in the SLDFRE EIS and other recently proposed drainage plans (refer to appendix A for details) differ from the strategies proposed by the San Joaquin Valley Drainage Program (1990a). The Bureau of Reclamation (USBR) in March 2007 signed a record of decision for an in-valley disposal option that would retire 194,000 acres of land, build 1,900 acres of evaporation ponds, and develop a treatment system to remove salt and selenium from drainwater. The recently proposed SLU Plans emphasize pumping drainage to the surface, storing approximately 33% in agricultural water re-use areas, treating selenium through biotechnology, enhancing the evaporation of water to concentrate salt, and identifying ultimate storage facilities for the remaining approximately 67% of waste selenium and salt. The treatment sequence of reuse, reverse osmosis, selenium bio-treatment, and enhanced solar evaporation is unprecedented and untested at the scale needed to meet plan requirements. All drainage management strategies that have been proposed

  6. Jorge Luis Borges and the New Physics: the Literature of Modern Science and the Science of Modern Literature

    Science.gov (United States)

    Mosher, Mark Robert

    1992-01-01

    By examining the works of the Argentine writer, Jorge Luis Borges, and the parallels it has with modern physics, literature and science converge in their quest for truth regarding the structure and meaning of the universe. The classical perception of physics as a "hard" science--that of quantitative, rational thought which was established during the Newtonian era--has been replaced by the "new physics," which integrates the so-called "soft" elements into its paradigm. It presents us with a universe based not exclusively on a series of particle-like interactions, or a "billiard-ball" hypothesis where discrete objects have a measurable position and velocity in absolute space and time, but rather on a combination of these mechanistic properties and those that make up the non-physical side of nature such as intuition, consciousness, and emotion. According to physicists like James Jeans science has been "humanized" to the extent that the universe as a "great machine" has been converted into a "great thought.". In nearly all his collections of essays and short stories, Borges complements the new physics by producing a literature that can be described as "scientized." The abstract, metaphysical implications and concerns of the new world-view, such as space, time, language, consciousness, free will, determinism, etc., appear repeatedly throughout Borges' texts, and are treated in terms that are remarkably similar to those expressed in the scientific texts whose authors include Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin Schrodinger. As a final comparison, Borges and post-modern physicists address the question of the individual's ability to ever comprehend the universe. They share an attitude of incredulity toward all models and theories of reality simply because they are based on partial information, and therefore seen only as conjectures.

    The San Francisco Bay Area in California and its surroundings are shown in this radar image from the Shuttle Radar Topography Mission (SRTM). On this image, smooth areas, such as the bay, lakes, roads and airport runways appear dark, while areas with buildings and trees appear bright. Downtown San Francisco is at the center and the city of Oakland is at the right across the San Francisco Bay. Some city areas, such as the South of Market district in San Francisco, appear bright due to the alignment of streets and buildings with respect to the incoming radar beam. Three of the bridges spanning the Bay are seen in this image. The Bay Bridge is in the center and extends from the city of San Francisco to Yerba Buena and Treasure Islands, and from there to Oakland. The Golden Gate Bridge is to the left and extends from San Francisco to Sausalito. The Richmond-San Rafael Bridge is in the upper right and extends from San Rafael to Richmond. Angel Island is the large island east of the Golden Gate Bridge, and lies north of the much smaller Alcatraz Island. The Alameda Naval Air Station is seen just below the Bay Bridge at the center of the image. Two major faults bounding the San Francisco-Oakland urban areas are visible on this image. The San Andreas fault, on the San Francisco peninsula, is seen on the left side of the image. The fault trace is the straight feature filled with linear reservoirs, which appear dark. The Hayward fault is the straight feature on the right side of the image between the urban areas and the hillier terrain to the east.This radar image was acquired by just one of SRTM's two antennas and, consequently, does not show topographic data, but only the strength of the radar signal reflected from the ground. This signal, known as radar backscatter, provides insight into the nature of the surface, including its roughness, vegetation cover and urbanization. The overall faint striping pattern in the images is a data processing artifact due to the

  11. Potential effect of algal productivity in the San Joaquin River on nitrate concentrations and isotope ratios

    2008-12-01

    The d15N of algae in nitrate-rich rivers is often about 4 to 5 permil lower than the d15N of the nitrate used by the algae. In cases where the algal productivity significantly depletes the available nitrate pool, the uptake of nitrate can cause significant increases in the d15N and d18O of the residual nitrate, resulting in isotope values similar to what would be expected for a major contribution of human or animal waste to the river. Furthermore, progressive algal uptake also causes nitrate d18O and d15N values that plot along slopes of about 1:2, consistent with assimilation and/or denitrification. One way to resolve the question of whether the high nitrate d15N and d18O values reflect a waste source, assimilation, or denitrification is to compare the simultaneous changes in nitrate concentrations, algal quality and loads, nitrate d15N and d18O, and the d15N, d13C, and C:N of the particulate organic matter, which is often dominated by algae in large rivers. As part of a recent investigation of nitrate and organic matter sources to the San Joaquin River (SJR), samples were collected twice-weekly to monthly for over 2 years from 7 mainstem sites (as well as many major and minor tributary sites) and analyzed for a wide range of chemical constituents and isotope ratios. The average nitrate d15N of mainstem sites was +11 permil, with a range of +2 to +17; the average d18O was +5 permil, with a range of -1 to +18. The potential impact of algal uptake on isotope ratios in the SJR was modeled using isotope and chemical data from 2 Lagrangian experiments in the San Luis Drain, a simple concrete-lined canal which drains into the SJR, has only a single input of water, and has algae similar to that in the SJR and a high productivity rate (Volkmar et al., in prep.).

  20. A case for historic joint rupture of the San Andreas and San Jacinto faults

    Lozos, Julian C.

    2016-01-01

    The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior. PMID:27034977

    Jorge Sagastume

    2011-07-01

    Full Text Available Una obra frecuentemente consultada por Jorge Luis Borges fue Matemáticas e imaginación, de E. Kasner y J. Newman, en la que se discute la teoría de los conjuntos (que es la rama de la matemática que estudia la relación entre conjuntos, propuesta por Georg Cantor (1845-1918, y mediante la cual se crea la aritmética transfinita (que va más allá de la finita y se establece un sistema epistémico para representar los diversos niveles del infinito. Así, Cantor le asigna a esas ininitudes la primera letra del alfabeto hebreo, el Aleph, seguido de un determinado número, dependiendo del nivel de infinitud (Aleph-cero, Aleph-uno, etc.. Borges, de esa manera, teje varias de sus narraciones en las que se trata el tema del ininito y del absoluto: un ejemplo de ello es la colección de relatos bajo el título El Aleph, que abre con el cuento «El inmortal» y cierra con el que le da el título a la colección. El presente ensayo tiene el propósito de estudiar «El inmortal» bajo la óptica cantoriana, para hablar de un absoluto en particular: el yo, y sugerir que no es posible establecer un vocabulario inal o una deinición deinitiva sobre el tema en cuestión. Tal imposibilidad, propone Borges, está dada en parte por la finitud lingüística, mientras que por otro lado la falibilidad de la memoria juega también un papel crucial en todo intento de deinición. Sin embargo, como buen ironista, el autor a través de «El inmortal» es capaz de proveer una redescripción del tema mediante un lenguaje transinito, sin pretender establecer un vocabulario inal sobre la materia, sino, al contrario, tratando de resolver ciertas paradojas a las vez que revela otras, promoviendo así el permanente diálogo entre las distintas disciplinas. Aunque el ensayo se enfoca en el análisis de «El inmortal», a fin de desarrollar el problema propuesto, también estudia otros relatos contenidos en El Aleph, y utiliza un acercamiento teórico que se enmarca en la

    2012-02-01

    Full Text Available The most celebrated book of Luis García Montero, Habitaciones separadas (1994, includes a dramatic monologue starring the figure of Jovellanos. Far from an anectodal fact, the presence of the asturian intellectual in this point of the lyric biography of García Montero comes to ratify the importance that the enlightened tradition has acquired in the poetic system of the author from Granada, main theoretical mentor of the so called poetry of experience. Following the reading suggested by Luis García Montero, we systematize the enlightened foundations of this aesthetic trend, which would find its modern roots in some capital notions of the eighteen century doctrine. Furthermore, we attempt to show how far those enlightened categories finally conform an axiological canon and reinforce García Montero’s theoretical opinion in favour of the value of the trade as an effective intervention of the poet in the social order. Finally, we suggest an interpretation of the «El insomnio de Jovellanos» in the light of the enlightened reading of the Modernity that the poet postulates in his essayistic discourse, a Modernity aimed to the transformation of the present against the repeated decrees of the end of History.

    Full Text Available Most of the poetry written by Luis Felipe Vivanco is characterised by its intimate reflection on a deeply personal reality focused on daily, familiar, religious and nature related issues. The aesthetics and style of his work were defined by the poet himself as «transcendental innermost realism». Despite this, Prosas propicias, his last work —posthumously published— contemplates the social and political reality in the last years of Franco’s dictatorship. This is a novelty in Vivanco´s poetry. The study of his new field is precisely the objective of this article.La mayor parte de la obra poética de Luis Felipe Vivanco se caracteriza por su reflexión intimista sobre una realidad hondamente personal centrada en lo cotidiano, lo familiar, lo religioso y la naturaleza, con una estética y estilo que el propio poeta denominó «realismo intimista trascendental». Sin embargo, en Prosas propicias, su última obra publicada póstumamente, reflexiona también sobre la realidad social y política de los últimos años de la dictadura franquista, lo que sin duda es algo novedoso en su poesía. El estudio de este nuevo ámbito temático es precisamente el objetivo de este artículo.

    Caxias is an orogenic gold deposit in the Sao Luis cratonic fragment, which is correlated with the Rhyacian terranes of the West-African Craton. The deposit postdates peak metamorphism (estimated at 2100 ± 15 Ma) and is hosted in a shear zone that cuts across schists of the Aurizona Group (2240 ± 5 Ma) and the Caxias Microtonalite. The emplacement age of the microtonalite, as determined in this work by SHRIMP U-Pb zircon dating, is 2009 ± 11 Ma and represents a latest age magmatic event in the Sao Luis cratonic fragment. Older zircon age of 2139 ± 10 Ma is interpreted as due to inheritance from the older granitoid or volcanic suites (magmatic sources?) or to contamination during emplacement. Lead isotope compositions indicate that the Pb incorporated in ore-related pyrite was probably sourced from regional, orogenic calc-alkaline granitoids of ca. 2160 Ma. Hydrothermal sericite from Caxias yielded a 40Ar/39Ar plateau age of 1990 ± 30 Ma, which combined with the emplacement age of the Caxias Microtonalite brackets the age of gold mineralization between 2009 ± 11 and 1990 ± 30 Ma.

    Full Text Available Je la dis que, je lui ai vu, il faut la parler, etc. Ces types de phrase, qui contiennent des aberrations sur des pronoms compléments, sont légion dans le français basilectal au Cameroun. L’observateur qui écoute ce parler au quotidien pointe du doigt la non maitrise de la norme standard du français. Cela n’est pas faux, mais à voir clair dans cette labyrinthe qu’est la norme, des motivations existent qui poussent les locuteurs à cette grammaticalisation . Pour essayer de comprendre ce casse-tête qu’est l’usage des pronoms compléments dans le français populaire au Cameroun nous avons fait appel à la théorie de la linguistique anthropologique telle expliquée par William Foley . Il s’agira selon cette théorie de faire une incursion dans la culture des Camerounais pour comprendre leur conception de l’usage des pronoms compléments notamment /le-la-lui-les-leur/ qui leur posent d’énormes difficultés. Les résultats de cette étude montrent que l’usage des pronoms compléments est fait de désillusions sur le genre desdits pronoms, de confusion d’autres classes grammaticales et d’hypercorrection due à l’insécurité linguistique.

    2009-07-01

    The San Cristobal Galapagos wind power project was described. With its unique endemic flora and fauna, the Galapagos Islands were declared a world heritage site and marine reserve. The San Cristobal wind project was initiated in 1999 to reduce the environmental impacts of energy use on the island, and has been operational since 2007. Three 800 kW wind turbines have been installed in order to reduce 52 per cent of the island's diesel generation. The project's high penetration wind-diesel hybrid system included 300 kW diesel generators, a 13.2 kV utility distribution system, and six 300 kW wind turbines. The project is located outside of Galapagos Petrel flight paths and nesting areas. Turbines from a factory in Spain were used. The wind turbine foundation was constructed from concrete sand and stone mined on the island. Photographs of the installation process were included. tabs., figs.

  18. SANS Measurement of Hydrides in Uranium

    International Nuclear Information System (INIS)

    SANS scattering is shown to be an effective method for detecting the presence of hydrogen precipitates in uranium. High purity polycrystalline samples of depleted uranium were given several hydriding treatments which included extended exposures to hydrogen gas at two different pressures at 630 C as well as a furnace anneal at 850 C followed by slow cooling in the near absence hydrogen gas. All samples exhibited neutron scattering that was in proportion to the expected levels of hydrogen content. While the scattering signal was strong, the shape of the scattering curve indicated that the scattering objects were large sized objects. Only by use of a very high angular resolution SANS technique was it possible to make estimates of the major diameter of the scattering objects. This analysis permits an estimate of the volume fraction and means size of the hydride precipitates in uranium

    An updated summary of a future large astrometric catalogue is presented, based on the two most important astrometric projects carried out by the Real Instituto y Observatorio de la Armada de San Fernando (ROA). The goal is to make a catalogue of positions and proper motions based on ROA's Cart du Ciel (CdC) and the Astrographic Catalogue (AC) San Fernando zone plates, and the HAMC2 meridian circle catalogue. The CdC and AC plates are being reduced together to provide first-epoch positions while HAMC2 will provide second-epoch ones. New techniques have been applied, that range from using a commercial flatbed scanner to the proper reduction schemes to avoid systematics from it. Only thirty plates (out of 540) remain to be processed, due to scanning problems that are being solved.

    International Nuclear Information System (INIS)

    The instrument SANS-1 at the Geesthacht neutron facility GeNF was used for scattering experiments in 2000 at 196 of 200 days of reactor and cold source operation. The utilisation was shared between the in-house R and D program and user groups from different universities and research centers. These measurements were performed and analysed either by guest scientists or GKSS staff. The focus of the work in 2000 at the experiment SANS-1 was the structural investigation of hydrogen containing substances such as biological macromolecules (ribosomes, protein-RNA-complexes, protein solutions, glycolipids and membranes), molecules which are important in the fields of environmental research (refractoric organic substances) and technical chemistry (surfactants, micelles).

  3. Anisotropy of SANS in metallic glasses

    International Nuclear Information System (INIS)

    SANS in metallic glasses is anisotropic and depends on the ribbon's orientation. Pd-based melt spun and Ni-based electrochemically deposited glasses exhibit different anisotropies. Both glasses contain scattering centers of the order of 40nm wide in the ribbon plane. In the melt-spun alloy, the scatterers are very thin along the thickness perpendicular to the substrate. In the deposited alloy however, the defects are long along the thickness perpendicular to the electrode

    2006-03-27

    Salt management has been a challenge to westside farmerssince the rapid expansion of irrigated agriculture in the 1900 s. Thesoils in this area are naturally salt-affected having formed from marinesedimentary rocks rich in sea salts rendering the shallow groundwater,and drainage return flows discharging into the lower reaches of the SanJoaquin River, saline. Salinity problems are affected by the importedwater supply from Delta where the Sacramento and San Joaquin Riverscombine. Water quality objectives on salinity and boron have been inplace for decades to protect beneficial uses of the river. However it wasthe selenium-induced avian toxicity that occurred in the evaporationponds of Kesterson Reservoir (the terminal reservoir of a planned but notcompleted San Joaquin Basin Master Drain) that changed public attitudesabout agricultural drainage and initiated a steady stream ofenvironmental legislation directed at reducing non-point source pollutionof the River. Annual and monthly selenium load restrictions and salinityand boron Total Maximum Daily Loads (TMDLs) are the most recent of thesepolicy initiatives. Failure by both State and Federal water agencies toconstruct a Master Drain facility serving mostly west-side irrigatedagriculture has constrained these agencies to consider only In-Valleysolutions to ongoing drainage problems. For the Westlands subarea, whichhas no surface irrigation drainage outlet to the San Joaquin River,innovative drainage reuse systems such as the Integrated Farm DrainageManagement (IFDM) offer short- to medium-term solutions while morepermanent remedies to salt disposal are being investigated. Real-timesalinity management, which requires improved coordination of east-sidereservoir releases and west-side drainage, offers some relief toGrasslands Basin farmers and wetland managers - allowing greater salinityloading to the River than under a strict TMDL. However, currentregulation drives a policy that results in a moratorium on all

    Maresca, Joseph W., Jr.; Padden, Robin R.; Cheng, Ralph T.; Seibel, Erwin

    1980-01-01

    High frequency (HF) radar measurements of the surface current averaged over the upper 0.5 m in San Pablo Strait were compared with current meter measurements of the subsurface current made at 9.4 m below mean lower low water (MLLW) over two 12.4-h tidal cycles. After averaging the radar and current meter data over two tidal cycles, a southerly (ebbing direction) surface current of 32 cm·s−1 was deduced from the radar measurements and a northerly (flooding direction) subsurface current of 7 cm·s−1 from the current meter measurements. This nontidal flow is maintained by freshwater discharge from the Sacramento–San Joaquin Rivers into Suisun and San Pablo Bays. The radar measurement technique provides quantitative estimates of the surface currents that previously were determined only from surface drifter studies.

  6. Space Radar Image of San Francisco, California

    Science.gov (United States)

    1994-01-01

    This is a radar image of San Francisco, California, taken on October 3,1994. The image is about 40 kilometers by 55 kilometers (25 miles by 34 miles) with north toward the upper right. Downtown San Francisco is visible in the center of the image with the city of Oakland east (to the right) across San Francisco Bay. Also visible in the image is the Golden Gate Bridge (left center) and the Bay Bridge connecting San Francisco and Oakland. North of the Bay Bridge is Treasure Island. Alcatraz Island appears as a small dot northwest of Treasure Island. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on orbit 56. The image is centered at 37 degrees north latitude, 122degrees west longitude. This single-frequency SIR-C image was obtained by the L-band (24 cm) radar channel, horizontally transmitted and received. Portions of the Pacific Ocean visible in this image appear very dark as do other smooth surfaces such as airport runways. Suburban areas, with the low-density housing and tree-lined streets that are typical of San Francisco, appear as lighter gray. Areas with high-rise buildings, such as those seen in the downtown areas, appear in very bright white, showing a higher density of housing and streets which run parallel to the radar flight track. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: the L-band (24 cm), C-band (6 cm) and X-band (3cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes

  7. Development of 40m SANS and Its Utilization Techniques

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

    This paper reviewed two types of network storage technique: NAS and SAN. After comparing and ana-lyzing, it concluded that the ultimate realization of network storage will be in the eventual convergence of NAS andSAN architectures. Currently, all the integration methods are based on the architecture level. This paper present-ed a device-level integration scheme based on IXP1200 network processor. The device can be used as an NAS fileserver or an SAN's storage node. Furthermore, it can be used as a bridge to connect NAS and SAN, and then beshared by their clients.

    Silica gels under study are materials intended for use as the packing sorbents in liquid chromatography (LC), namely in gel permeation chromatography (GPC). The quality of silica for LC should meet strict physical and chemical parameters. Especially in GPC is very important to know pore size and pore shape because they control the whole process of chromatographic separation. Pore size and thickness of pore wall can be measured by various methods. SANS technique is a nondestructive method providing an average information about a large number of scattering object in our case about objects (pore or wall) in silica and their shape. (author)

  11. The radiological accident in San Salvador

    International Nuclear Information System (INIS)

    On 5 February 1989, a radiological accident occurred at an industrial irradiation facility near San Salvador, the capital of the Republic of El Salvador. Prepackaged medical products are sterilized at the facility by irradiation by means of an intensely radioactive cobalt-60 source in a movable source rack. The accident happened when this source rack became stuck in the irradiation position. The operator bypassed the irradiator's already degraded safety systems and entered the radiation room with two other workers to free the source rack manually. The three workers were exposed to high radiation doses and developed the acute radiation syndrome. Their initial hospital treatment in San Salvador and subsequent more specialized treatment in Mexico City were effective in countering the acute effects. However, the legs and feet of two of the three men were so seriously injured that amputation was required. The worker who had been most exposed died six and a half months after the accident, his death being attributed to residual lung damage due to irradiation, exacerbated by injury sustained during treatment. The report details the events leading up to the accident, the circumstances of the accident itself and the response to it. From the facts established, lessons are derived for operators and suppliers of irradiators, national authorities, medical staff and international organizations. Detailed information on dosimetric and medical aspects of the accident for the specialist reader is presented in the appendices and annexes. 20 figs, 9 tabs, 24 photographs

  12. Synthetic seismicity for the San Andreas fault

    Directory of Open Access Journals (Sweden)

    S. N. Ward

    1994-06-01

    Full Text Available Because historical catalogs generally span only a few repetition intervals of major earthquakes, they do not provide much constraint on how regularly earthquakes recur. In order to obtain better recurrence statistics and long-term probability estimates for events M ? 6 on the San Andreas fault, we apply a seismicity model to this fault. The model is based on the concept of fault segmentation and the physics of static dislocations which allow for stress transfer between segments. Constraints are provided by geological and seismological observations of segment lengths, characteristic magnitudes and long-term slip rates. Segment parameters slightly modified from the Working Group on California Earthquake Probabilities allow us to reproduce observed seismicity over four orders of magnitude. The model yields quite irregular earthquake recurrence patterns. Only the largest events (M ? 7.5 are quasi-periodic; small events cluster. Both the average recurrence time and the aperiodicity are also a function of position along the fault. The model results are consistent with paleoseismic data for the San Andreas fault as well as a global set of historical and paleoseismic recurrence data. Thus irregular earthquake recurrence resulting from segment interaction is consistent with a large range of observations.

    1992-03-01

    The San Joaquin - Tulare Conjunctive Use Model (SANTUCM) was originally developed for the San Joaquin Valley Drainage Program to evaluate possible scenarios for long-term management of drainage and drainage - related problems in the western San Joaquin Valley of California. A unique aspect of this model is its coupling of a surface water delivery and reservoir operations model with a regional groundwater model. The model also performs salinity balances along the tributaries and along the main stem of the San Joaquin River to allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. This document is a detailed description of the various subroutines, variables and parameters used in the model.

    2014-12-01

    The largest estuary on the west coast of North America, San Francisco Bay is an ecosystem of enormous biodiversity, and also enormous human impact. The benthos has experienced dredging, occupation by invasive species, and over a century of sediment input as a result of hydraulic mining. Although the Bay's great cultural and ecological importance has inspired numerous surveys of the benthic macrofauna, to date there has been almost no investigation of the microbial communities on the Bay floor. An understanding of those microbial communities would contribute significantly to our understanding of both the biogeochemical processes (which are driven by the microbiota) and the physical processes (which contribute to microbial distributions) in the Bay. Here, we present the first broad survey of bacterial and archaeal taxa in the sediments of the San Francisco Bay. We conducted 16S rRNA community sequencing of bacteria and archaea in sediment samples taken bimonthly for one year, from five sites spanning the salinity gradient between Suisun and Central Bay, in order to capture the effect of both spatial and temporal environmental variation on microbial diversity. From the same samples we also conducted deep sequencing of a nitrogen-cycling functional gene, nirS, allowing an assessment of evolutionary diversity at a much finer taxonomic scale within an important and widespread functional group of bacteria. We paired these sequencing projects with extensive geochemical metadata as well as information about macrofaunal distribution. Our data reveal a diversity of distinct biogeographical patterns among different taxa: clades ubiquitous across sites; clades that respond to measurable environmental drivers; and clades that show geographical site-specificity. These community datasets allow us to test the hypothesis that salinity is a major driver of both overall microbial community structure and community structure of the denitrifying bacteria specifically; and to assess

  4. Beneficial Reuse of San Ardo Produced Water

    This DOE funded study was performed to evaluate the potential for treatment and beneficial reuse of produced water from the San Ardo oilfield in Monterey County, CA. The potential benefits of a successful full-scale implementation of this project include improvements in oil production efficiency and additional recoverable oil reserves as well as the addition of a new reclaimed water resource. The overall project was conducted in two Phases. Phase I identified and evaluated potential end uses for the treated produced water, established treated water quality objectives, reviewed regulations related to treatment, transport, storage and use of the treated produced water, and investigated various water treatment technology options. Phase II involved the construction and operation of a small-scale water treatment pilot facility to evaluate the process's performance on produced water from the San Ardo oilfield. Cost estimates for a potential full-scale facility were also developed. Potential end uses identified for the treated water include (1) agricultural use near the oilfield, (2) use by Monterey County Water Resources Agency (MCWRA) for the Salinas Valley Water Project or Castroville Seawater Intrusion Project, (3) industrial or power plant use in King City, and (4) use for wetlands creation in the Salinas Basin. All of these uses were found to have major obstacles that prevent full-scale implementation. An additional option for potential reuse of the treated produced water was subsequently identified. That option involves using the treated produced water to recharge groundwater in the vicinity of the oil field. The recharge option may avoid the limitations that the other reuse options face. The water treatment pilot process utilized: (1) warm precipitation softening to remove hardness and silica, (2) evaporative cooling to meet downstream temperature limitations and facilitate removal of ammonia, and (3) reverse osmosis (RO) for removal of dissolved salts, boron

    The San Francisco gartersnake Thamnophis sirtalis tetrataenia has been federally listed as endangered since 1967, but little demographic information exists for this species. We examined the demography of a San Francisco gartersnake population on approximately 213 ha of California coastal prairie in San Mateo County, California, from 2007 to 2010. The best-supported mark-recapture model indicated annual variation in daily capture probabilities and annual survival rates. Abundance increased throughout the study period, with a mean total population from 2008 to 2010 of 443 (95% CI = 313-646) individuals. Annual survival was slightly greater than that of most other gartersnakes, with an annual probability of survival of 0.78 (0.55-0.95) in 2008-2009 and 0.75 (0.49-0.93) in 2009-2010. Mean annual per capita recruitment rates were 0.73 (0.02-2.50) in 2008-2009 and 0.47 (0.02-1.42) in 2009-2010. From 2008 to 2010, the probability of an increase in abundance at this site was 0.873, with an estimated increase of 115 (-82 to 326) individuals. The estimated population growth rate in 2008-2009 was 1.52 (0.73-3.29) and in 2009-2010 was 1.21 (0.70-2.17). Although this population is probably stable or increasing in the short term, long-term studies of the status of the San Francisco gartersnake at other sites are required to estimate population trends and to elucidate mechanisms that promote the recovery of this charismatic member of our native herpetofauna.

  7. San Onofre - the evolution of outage management

    International Nuclear Information System (INIS)

    With the addition of units 2 and 3 to San Onofre nuclear station in 1983 and 1984, it became evident that a separate group was needed to manage outages. Despite early establishment of a division to handle outages, it was a difficult journey to make the changes to achieve short outages. Early organizational emphasis was on developing an error-free operating environment and work culture. This is difficult for a relatively large organization at a three-unit site. The work processes and decision styles were designed to be very deliberate with many checks and balances. The organization leadership and accountability were focused in the traditional operations, maintenance, and engineering divisions. Later, our organization emphasis shifted to achieving engineering excellence. With a sound foundation of operating and engineering excellence, our organizational focus has turned to achieving quality outages. This means accomplishing the right work in a shorter duration and having the units run until the next refueling

    Isla San Cristobal, the most easterly of the Galapagos Islands, consists of two parts: a large volcano constitutes the southwest half of the island and an irregular apron of small cones and flows makes up the northeast half. As some of the younger flows on the flanks of the large volcano are reversely magnetized, the minimum age of the volcano is 0.7 my, which is the age of the Brunhes-Matuyama reversal boundary. The true age is probably several times greater. The cones and flows to the northeast are all normally magnetized. The between-site angular dispersion of virtual poles is 11.3?? - a value consistent with mathematical models for the latitude dependence of geomagnetic secular variation. ?? 1971.

    A study was conducted to determine the suitability of the San Fernando Observatory's 61 cm (24 inch) aperture vacuum solar telescope and 3 m (118 inch) focal length vacuum spectroheliograph for Stokes Polarimetry measurements. The polarization characteristics of these two instruments was measured by determining their Mueller matrices as a function of telescope orientation, field angle, wavelength, grating type, and position of the measuring beam in the telescope entrance window. In general, the polarizing and depolarizing properties are small so that inversion of the system Mueller matrix will permit the accurate measurement of Stokes profiles for vector magnetic field determination. A proposed polarimeter design based on the use of a TV camera system to simultaneously scan six different polarization components of a given line profile is described. This design, which uses no rotating optics or electronic modulators and makes efficient use of the available irradiance, promises to yield high quality vector magnetograms.

    1989-09-01

    The lower Eocene San Jose Formation in the central portion of the San Juan basin (Gobernador-Vigas Canyon area) consists of the Cuba Mesa, Regina, Llaves, and Tapicitos Members. Well log data indicate that, from its 100-m thickness, the Cuba Mesa Member thins toward the basin center and pinches out to the northeast by lat. 36{degree}40'N, long. 107{degree}19'W. The Regina Member has the most extensive outcrops in the central basin, and it decreases in sandstone/mud rock ratio to the north. The Llaves and Tapicitos Members occur only at the highest elevations, are thin due to erosion, and are not mappable as separate units. Well log data and 1,275 m of measured stratigraphic section in the Regina, Llaves, and Tapicitos Members indicate these strata are composed of approximately 35% medium to coarse-grained sandstone and 65% fine-grained sandstone and mud rock. Sedimentology and sediment-dispersal patterns indicate deposition by generally south-flowing streams that had sources to the northwest, northeast, and east. Low-sinuosity, sand-bedded, braided( ) streams shifted laterally across about 1 km-wide channel belts to produce sheet sandstones that are prominent throughout the San Jose Formation. Subtle levees separated channel environments from floodplain and local lacustrine areas. Avulsion relocated channels periodically to areas on the floodplain, resulting in the typically disconnected sheet sandstones within muddy overbank deposits of the Regina Member.

  12. Developing solar power programs : San Francisco's experience

    International Nuclear Information System (INIS)

    This keynote address discussed an array of solar programs initiated in government-owned buildings in San Francisco. The programs were strongly supported by the city's mayor,and the voting public. Known for its fog and varying microclimates, 11 monitoring stations were set up throughout the city to determine viable locations for the successful application of solar technologies. It was observed that 90 per cent of the available sunshine occurred in the central valley, whereas fog along the Pacific shore was problematic. Seven of the monitoring sites showed excellent results. Relationships with various city departments were described, as well as details of study loads, load profiles, electrical systems, roofs and the structural capabilities of the selected government buildings. There was a focus on developing good relations with the local utility. The Moscone Convention Center was selected for the program's flagship installation, a 675 kW solar project which eventually won the US EPA Green Power Award for 2004 and received high press coverage. Cost of the project was $4.2 million. 825,000 kWh solar electricity was generated, along with 4,500,000 kWh electricity saved annually from efficiency measures, resulting in a net reduction of 5,325,000 kWh. Savings on utilities bills for the center were an estimated $1,078,000. A pipeline of solar projects followed, with installations at a sewage treatment plant and a large recycling depot. A program of smaller sites included libraries, schools and health facilities. Details of plans to apply solar technology to a 500 acre redevelopment site in southeast San Francisco with an aging and inadequate electrical infrastructure were described. A model of efficient solar housing for the development was presented, with details of insulation, windows, heating ventilation and air-conditioning (HVAC), water heating, lighting, appliances and a 1.2 kilowatt solar system. Peak demand reductions were also presented. tabs., figs

Bangpungtongsung-san extracts were showed the effect of decreased the activity of glycerol-3-phosphate dehydrogenase(GPDH on the high dosage(1.0㎎/㎖ and Specially, alcohol extract of Bangpungtongsung -san was clear as time goes by high concentration. 3. Bangpungtongsung-san extracts were showed tries to compare the effect of lipolysis, alcohol extract of Bangpungtongsung-san on the high dosage(1.0㎎/㎖ was observed the effect is higher than water extract. 4. Investigated the histological changes in porcine fat tissue after treated Bangpungtongsung-san extracts, we knew that water extract of Bangpungtongsung-san was showed the effect of lipolysis on the high dosage(10.0㎎/㎖ and alcohol extract of Bangpungtongsung-san was showed significant activity to the lysis of cell membranes in all concentration. Conclusion : These results suggest that Bangpungtongsung-san extracts efficiently
