    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.

  10. Geothermal resource assessment of western San Luis Valley, Colorado

    Energy Technology Data Exchange (ETDEWEB)

    Zacharakis, Ted G.; Pearl, Richard Howard; Ringrose, Charles D.

    1983-01-01

    The Colorado Geological Survey initiated and carried out a fully integrated assessment program of the geothermal resource potential of the western San Luis Valley during 1979 and 1980. The San Luis Valley is a large intermontane basin located in southcentral Colorado. While thermal springs and wells are found throughout the Valley, the only thermal waters found along the western part of the Valley are found at Shaw Warm Springs which is a relatively unused spring located approximately 6 miles (9.66 km) north of Del Norte, Colorado. The waters at Shaws Warm Spring have a temperature of 86 F (30 C), a discharge of 40 gallons per minute and contain approximately 408 mg/l of total dissolved solids. The assessment program carried out din the western San Luis Valley consisted of: soil mercury geochemical surveys; geothermal gradient drilling; and dipole-dipole electrical resistivity traverses, Schlumberger soundings, Audio-magnetotelluric surveys, telluric surveys, and time-domain electro-magnetic soundings and seismic surveys. Shaw Warm Springs appears to be the only source of thermal waters along the western side of the Valley. From the various investigations conducted the springs appear to be fault controlled and is very limited in extent. Based on best evidence presently available estimates are presented on the size and extent of Shaw Warm Springs thermal system. It is estimated that this could have an areal extent of 0.63 sq. miles (1.62 sq. km) and contain 0.0148 Q's of heat energy.

  12. Ground water recharge to the aquifers of northern San Luis Valley, Colorado: A remote sensing investigation

    Science.gov (United States)

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

    1976-01-01

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

  14. Forecasting Selenium Discharges to the San Francisco Bay-Delta Estuary: Ecological Effects of A Proposed San Luis Drain Extension

    Science.gov (United States)

    Presser, Theresa S.; Luoma, Samuel N.

    2006-01-01

    Selenium discharges to the San Francisco Bay-Delta Estuary (Bay-Delta) could change significantly if federal and state agencies (1) approve an extension of the San Luis Drain to convey agricultural drainage from the western San Joaquin Valley to the North Bay (Suisun Bay, Carquinez Strait, and San Pablo Bay); (2) allow changes in flow patterns of the lower San Joaquin River and Bay-Delta while using an existing portion of the San Luis Drain to convey agricultural drainage to a tributary of the San Joaquin River; or (3) revise selenium criteria for the protection of aquatic life or issue criteria for the protection of wildlife. Understanding the biotransfer of selenium is essential to evaluating effects of selenium on Bay-Delta ecosystems. Confusion about selenium threats to fish and wildlife stem from (1) monitoring programs that do not address specific protocols necessary for an element that bioaccumulates; and (2) failure to consider the full complexity of the processes that result in selenium toxicity. Past studies show that predators are more at risk from selenium contamination than their prey, making it difficult to use traditional methods to predict risk from environmental concentrations alone. This report presents an approach to conceptualize and model the fate and effects of selenium under various load scenarios from the San Joaquin Valley. For each potential load, progressive forecasts show resulting (1) water-column concentration; (2) speciation; (3) transformation to particulate form; (4) particulate concentration; (5) bioaccumulation by invertebrates; (6) trophic transfer to predators; and (7) effects on those predators. Enough is known to establish a first-order understanding of relevant conditions, biological response, and ecological risks should selenium be discharged directly into the North Bay through a conveyance such as a proposed extension of the San Luis Drain. The approach presented here, the Bay-Delta selenium model, determines the mass, fate

    Vorum, M.; Coury, G.E.; Goering, S.W.; Fritzler, E.A.

    1978-02-01

    Information on the geothermal resources of the San Luis Valley, Colorado, has been gathered and reviewed and a preliminary, quantitative assessment of the magnitude and quality of resources present was carried out. Complete process designs were developed for the processes of producing crystal sugar from beets and for malting barley for use in the brewing industry, in each case adapting the processes to use a 302/sup 0/F geothermal water supply as the main process energy source. A parametric design analysis was performed for a major pipeline to be used to ship geothermal water, and thus deliver its heat, out of the San Luis Valley to three major Colorado cities along the eastern threshold of the Rocky Mountains. Cost estimates for capital equipment and energy utilization are presented. The analyses of the two process applications indicate favorable economics for conversion and operation as geothermally-heated plants. A major geothermal water pipeline for this region is seriously limited on achievement of the economy of scale by the physical absence of significant demand for heat energy. Finally, the development and utilization of Colorado's San Luis Valley geothermal groundwaters hold the potential to contribute to the prudent and beneficial management of that area's natural water resources systems.

    Full Text Available La base fundamental de la identidad de los habitantes de la provincia de San Luis (Argentina y de su historiografía, es el axioma que el pueblo puntano se inmoló por el proyecto sanmartiniano. El Gobernador Intendente Vicente Dupuy (1814-1820 fue el principal colaborador de José de San Martin en la provincia, y el coordinador de las donaciones de bienes y vidas para la causa. Contaba con el apoyo del “cabildo sanmartiniano”, un grupo de vecinos que secundaban sus ideales, apoyaban sus iniciativas y colaboraban materialmente. Pero luego de la caída del gobierno central en 1820 no se ofrece una interpretación sobre el cambio de proyecto político que representó el nuevo Gobernador, José Santos Ortiz (1820-1829. Si se consideran conjuntamente las oposiciones de un grupo de vecinos levantadas durante el gobierno de Dupuy y el accionar de Santos Ortiz durante su mandato, cabe preguntarse: ¿los cabildantes terratenientes apoyaron la gesta sanmartiniana por convicción, o se vieron forzados a hacerlo por la imposición de un grupo en el poder? ¿Representó Santos Ortiz el proyecto de lo que el grupo terrateniente buscaba y no pudo obtener mientras se llevaba delante el plan sanmartiniano? En este trabajo se busca comparar los objetivos primarios de ambos gobernadores durante sus mandatos, con el fin de vislumbrar cuál de los planes de gobierno representaba los ideales y necesidades de los grandes terratenientes de la ciudad de San Luis.

    Spatial and temporal distribution of the radioisotopes concentrations were determined in sediments near the surface and core samples extracted from two reservoirs located in an arid region close to Chihuahua City, Mexico. 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. 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.

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

    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.

    San Luis National Wildlife Refuge Complex to meetReclamation s obligations for Level 4 water supply under the CentralValley Project Improvement Act. Hydrogeological assessment of the EastBear Creek Unit of the San Luis National Wildlife Refuge was conductedusing a combination of field investigations and a survey of availableliterature from past US Geological Survey Reports and reports by localgeological consultants. Conservative safe yield estimates made using theavailable data show that the East Bear Creek Unit may have sufficientgroundwater resources in the shallow groundwater aquifer to meet aboutbetween 25 percent and 52 percent of its current Level II and between 17percent and 35 percent of its level IV water supply needs. The rate ofsurface and lateral recharge to the Unit and the design of the well fieldand the layout and capacity of pumped wells will decide both thepercentage of annual needs that the shallow aquifer can supply andwhether this yield is sustainable without affecting long-term aquiferquality. In order to further investigate the merits of pumping the nearsurface aquifer, which appears to have reasonable water quality for usewithin the East Bear Creek Unit -- monitoring of the potential sources ofaquifer recharge and the installation of a pilot shallow well would bewarranted. Simple monitoring stations could be installed both upstreamand downstream of both the San Joaquin River and Bear Creek and beinstrumented to measureriver stage, flow and electrical conductivity.Ideally this would be done in conjunction with a shallow pilot well,pumped to supply a portion of the Unit's needs for the wetland inundationperiod.

    Full Text Available We recorded 12 exotic bird species in San Luis Potosi, Mexico and adjacent areas. Obtained data were collected during the period August 2012 to August 2013. From the total of recorded species, eight are confirmations (Anas platyrhynchos domesticus, Cairina moschata, Bubulcus ibis, Columba livia, Sturnus vulgaris, Turdus rufopalliatus, Quiscalus mexicanus and Passer domesticus and four are new records (Aratinga canicularis, Amazona oratrix, A. autumnalis and Cyanocorax yncas. Although not all exotic species represent a risk because of the lack of the necessary resources for the establishment of abundant viable populations, it is important to publicize their status in the region. Therefore, knowing the presence of exotic species in a new distribution area is important for monitoring its establishment and colonization, and defining management, control and eradication programs of these species, along with environmental education programs that would lead to a better understanding of impacts that these species can cause.

    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.

    In plant communities, the species distribution patterns and their relationships with environmental factors are of central importance in ecology. In San Luis Potosí of Mexico, woodlands of Pinus cembroides and P. johannis are sympatric, but P. cembroides tends to be located in South and Southwest slopes, in more disturbed sites; unlike, P. johannis, is mostly distributed in mesic areas, in North and Northeast slopes. The aim of this study was to analyze the influence of some physical factors on the floristic similarity of pinyon pine P. cembroides and P. johannis. The study area was located in the Sierra San Miguelito, San Luis Potosí, Mexico. We selected 40 sampling units spread over an area of 50km2. In each unit, we laid out two 20m long lines perpendicular to each other, in which we recorded cover data of the plant species intercepted. We developed two data matrices, the first one including cover values of 91 species, and the second one, considering seven topographical, climatic, and solar radiation variables. We applied cluster analysis and ordination to explore the influence of environmental variables on the floristic differentiation of pinyon pine woodlands. Clustering showed six groups, the first three characterized by P. cembroides. The ordination showed that variance represented by the first three axes was 65.9%. Axis 1 was positively correlated with altitude and negatively with mean annual temperature; axes two and three, showed low correlation with the variables tested. P. cembroides woodlands and accompanying flora tend to be located in lower altitude, higher mean annual temperature, and mainly in South-Southwestern slopes. In contrast, stands of P. johannis, mixed stands of P. johannis-P. cembroides, and Quercus potosina, were usually founded in greater altitudes, mean annual temperature slightly lower, and North-Northeastern exposure. The sites of these monospecific and mixed woodlands with associated species, indicators of environmental variables

    This report summarizes the results of a study conducted by Argonne National Laboratory’s (Argonne’s) Environmental Science Division for the U.S. Department of the Interior Bureau of Land Management (BLM). The study analyzed the regional effects of potential visual impacts of solar energy development on three BLM-designated solar energy zones (SEZs) in the San Luis Valley (SLV) in Colorado, and, based on the analysis, made recommendations for or against regional compensatory mitigation to compensate residents and other stakeholders for the potential visual impacts to the SEZs. The analysis was conducted as part of the solar regional mitigation strategy (SRMS) task conducted by BLM Colorado with assistance from Argonne. Two separate analyses were performed. The first analysis, referred to as the VSA Analysis, analyzed the potential visual impacts of solar energy development in the SEZs on nearby visually sensitive areas (VSAs), and, based on the impact analyses, made recommendations for or against regional compensatory mitigation. VSAs are locations for which some type of visual sensitivity has been identified, either because the location is an area of high scenic value or because it is a location from which people view the surrounding landscape and attach some level of importance or sensitivity to what is seen from the location. The VSA analysis included both BLM-administered lands in Colorado and in the Taos FO in New Mexico. The second analysis, referred to as the SEZ Analysis, used BLM visual resource inventory (VRI) and other data on visual resources in the former Saguache and La Jara Field Offices (FOs), now contained within the San Luis Valley FO (SLFO), to determine whether the changes in scenic values that would result from the development of utility-scale solar energy facilities in the SEZs would affect the quality and quantity of valued scenic resources in the SLV region as a whole. If the regional effects were judged to be significant, regional

    A problem exists in determining which parts of the San Luis basin were depositional sites during three Tertiary tectonic events: early Tertiary (Laramide) transpression/compression, mid-Tertiary volcanism, and late Tertiary (Rio Grande rift) extension. Earlier studies have been hampered by incomplete knowledge of regional characteristics of poorly exposed early Tertiary rocks and by reliance upon inconclusive pollen age determinations. For simple petrologic analysis of well cuttings from boreholes across the basin, the authors must reinterpret the timing and mode of basin development. Applying general petrologic characteristics in well log correlations, it is apparent that the western part (Monte Vista graben) of the San Luis basin was an active depositional basin during all three of the Tertiary tectonic events, whereas the eastern part (Baca graben) is primarily a result of the late Tertiary rift episode.

    Sediments of the Alamosa Formation spanning the upper part of the Gauss and most of the Matuyama Chrons were recovered by coring in the high (2300 m) San Luis Valley of south-central Colorado. The study site is located at the northern end of the Rio Grande rift. Lithologic changes in the core sediments provide evidence of events leading to integration of the San Luis drainage basin into the Rio Grande. The section, which includes the Huckleberry Ridge Ash (2.02 Ma) and spans the entire Matuyama Chron, contains pollen, and invertebrate and vertebrate fossils. Stable isotope analyses of inorganic and biogenic carbonate taken over most of the core indicate substantially warmer temperatures than occur today in the San Luis Valley. At the end of the Olduvai Subchron, summer precipitation decreased, summer pan evaporation increased, and temperatures increased slightly compared to the earlier climate represented in the core. By the end of the Jaramillo Subchron, however, cold/wet and warm/dry cycles become evident and continue into the cold/wet regime associated with the deep-sea oxygen-isotope Stage 22 glaciation previously determined from outcrops at the same locality. Correspondence between the Hansen Bluff climatic record and the deep-sea oxygen-isotope record (oxygen-isotope stages from about 110-18) is apparent, indicating that climate at Hansen Bluff was responding to global climatic changes. ?? 1992.

    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.

    Management for migratory birds at an ecosystem scale requires forming cooperative partnerships with the private sector. To be effective, however, wildlife managers must understand the economic and social attitudes of private landowners to ensure that strategies involving stakeholders are viable and can be implemented. We documented attitudes of farmers in the San Luis Valley (SLV) of Colorado toward Rocky Mountain Population greater sandhill cranes (Grus canadensis tabida) using a self administered, mail-back survey. Overall response rate was 46.7%. Viewing sandhill cranes in the SLV was considered somewhat important or important by 78.6% of respondents. In contrast, only 62.1% of respondents indicated that viewing sandhill cranes was somewhat important or important on their own land. Farmers' attitudes toward viewing sandhill cranes on their own property were related (P=0.02) to perceived conflicts with crop production. The extent of crane use (P=0.04) was the only variable we tested that predicted whether conflicts were reported. Our results suggest that partnerships between farmers and natural resource agencies concerned with management of sandhill cranes may be viable. However, the role of farmers in any proposed management strategy must be examined carefully because there may be an upper limit of crane use on private land that farmers will tolerate.

    Lawrence Berkeley National Laboratory (LBNL), LFR Levine-Fricke (LFR), the U.S. Bureau of Reclamation (USBR) and the Panoche Water District, have completed a pilot-scale test of the viability of land application of selenium- (Se-) enriched San Luis Drain (SLD) sediments. The project was initiated in October 1998 by LBNL. LFR assumed the role of primary subcontractor on the project in July 2001. Substantial portions of this report, describing work performed prior to November 2000, were previously prepared by LBNL personnel. The data set, findings, and recommendations are herein updated with information collected since November 2000. 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 that 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 groundwater; reduced productivity of farm crops; and Se uptake by wild and crop plants. This report describes field and laboratory activities carried out from 1998 through February 2002, and results of these investigations.

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

    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

    Full Text Available Las quebradas La Cristalina y La Risaralda son las fuentes que abastecen el acueducto del área urbana del municipio de San Luis, Antioquia. El propósito de este estudio fue elaborar un mapa de calidad de agua que sirva como base de comparación de la evolución de las quebradas y justifique la inversión de los recursos del Municipio en el mejoramiento prioritario de los tramos más críticos. Para establecer la calidad del agua se determinaron indicadores físicos, químicos y biológicos, entre ellos algunas características físicas de las quebradas como tipo de sustrato, cobertura de riberas y hábitats acuáticos, temperatura, conductividad, oxígeno, pH, coliformes y macroinvertebrados acuáticos. A partir de los datos colectados se calcularon los índices BMWP/Col1, ASPT, ETP, índice de dípteros y de equidad. Con los resultados obtenidos del ASPT se construyó el mapa de calidad de agua para ambas quebradas. Las quebradas están bien oxigenadas debido a la turbulencia provocada por la conformación rocosa de su lecho, que a su vez permite la diversidad de macroinvertebrados acuáticos. Sin embargo, algunos tramos de estas corrientes están sometidos a contaminación de origen doméstico y agropecuario, lo cual limita sus condiciones de uso.The streams La Cristalina and La Risaralda are the water sources for the urban area of the Municipality of San Luis, Antioquia. The intention of this study was to develop a map of water quality that serves as base as comparison of the evolution of the streams and allows the high-priority destination of the resources of the Municipality in the improvement of those more critical sections. In order to determine the quality of the water, parameters and some characteristics of the stream that can alter the quality of the water were measured, like substrate of the bed, cover of banks, aquatic habitats, temperature, conductivity, oxygen, pH, coliforms, and aquatic macroinvertebrates.

  9. Green Net Regional Product for the San Luis Basin, Colorado: an economic measure of regional sustainability.

    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.

    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.

    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.

    In San Luis Potosí City cervical infection by human papillomavirus type 16 (HPV16) associated to dysplastic lesions is more prevalent in younger women. In this work HPV16 subtypes and variants associated to low-grade intraepithelial lesions (LSIL), high-grade intraepithelial lesions (HSIL) and invasive cervical cancer (ICC) of 38 women residing in San Luis Potosí City were identified by comparing their E6 open reading frame sequences. Three European (E) variants (E-P, n = 27; E-T350G, n = 7; E-C188G, n = 2) and one AA-a variant (n = 2) were identified among the 38 HPV16 sequences analyzed. E-P variant sequences contained 23 single nucleotide changes, two of which (A334G, A404T) had not been described before and allowed the phylogenetic separation from the other variants. E-P A334G sequences were the most prevalent (22 cases, 57.9%), followed by the E-P Ref prototype (8 cases, 21.1%) and E-P A404T (1 case, 2.6%) sequences. The HSIL + ICC fraction was 0.21 for the E-P A334G variants and 0.00 for the E-P Ref variants. We conclude that in the women included in this study the HPV16 E subtype is 19 times more frequent than the AA subtype; that the circulating E variants are E-P (71.1%) > E-T350G (18.4%) > E-C188G (5.3%); that 71.0% of the E-P sequences carry the A334G single nucleotide change and appear to correspond to a HPV16 variant characteristic of San Luis Potosi City more oncogenic than the E-P Ref prototype.

  17. Forecasting selenium discharges to the San Francisco Bay-Delta Estuary: ecological effects of a proposed San Luis drain extension

    During the next few years, federal and state agencies may be required to evaluate proposals and discharge permits that could significantly change selenium (Se) inputs to the San Francisco Bay-Delta Estuary (Bay-Delta), particularly in the North Bay (i.e., Suisun Bay and San Pablo Bay). These decisions may include discharge requirements for an extension of the San Luis Drain (SLD) to the estuary to convey subsurface agricultural drainage from the western San Joaquin Valley (SJV), a renewal of an agreement to allow the existing portion of the SLD to convey subsurface agricultural drainage to a tributary of the San Joaquin River (SJR) (coincident with changes in flow patterns of the lower SJR), and refinements to promulgated Se criteria for the protection of aquatic life for the estuary. Understanding the biotransfer of Se is essential to evaluating the fate and impact of proposed changes in Se discharges to the Bay-Delta. However, past monitoring programs have not addressed the specific protocols necessary for an element that bioaccumulates. Confusion about Se threats in the past have stemmed from failure to consider the full complexity of the processes that result in Se toxicity. Past studies show that predators are more at risk from Se contamination than their prey, making it difficult to use traditional methods to predict risk from environmental concentrations alone. In this report, we employ a novel procedure to model the fate of Se under different, potentially realistic load scenarios from the SJV. For each potential load, we progressively forecast the resulting environmental concentrations, speciation, transformation to particulate form, bioaccumulation by invertebrates, trophic transfer to predators, and effects in those predators. Enough is known to establish a first order understanding of effects should Se be discharged directly into the North Bay via a conveyance such as the SLD. Our approach uses 1) existing knowledge concerning the biogeochemical

    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

    The known geologic data of the San Luis Basin are reviewed and related to an understanding of the hydrogeothermal potential of the Alamosa-Monte Vista area. The physiographic setting of the region, the structural framework of the basin, and its influence on the stratigraphic makeup of the rock sequence, which in turn control the occurrence of potential deep water reservoirs, are reviewed. It is suggested that the San Luis Basin was well-developed by Miocene time, and that although the basin was modified by Neogene faulting, it is essentially a late Laramide event having been produced during the Paleogene. Attention is also given to high heat flow along the Rio Grande Rift and to the geothermal gradient of the San Luis Basin. The confined aquifer is then considered in respect to its hydrogeology, water quality, and as to the legal aspects of the system. (LEW)

    The Joya Prieta is a Quaternary maar volcano emplaced at the western sector of the Sierra Madre Oriental fold and thrust belt. The crater is located at the axis of an open Laramide fold with a N20°W axis trend. It is the most easterly structure of the Santo Domingo Group, a cluster of intraplate maars and tuff-rings northeast of San Luis Potosí. A characteristic feature of these maars is that they are emplaced in close relationship with anticlines, exposing impressive inner crater walls of folded strata. In the Joya Prieta maar, the calcareous basement rocks are clearly exposed and unconformably overlain by the volcanic succession. A generalized stratigraphic sequence registers, from base to top, olivine-bearing basalt lava resting unconformably atop El Abra Formation limestone. The lava is overlain by thick and oxidized scoria and spatter agglomerate that grades into a moderately sorted spatter-fall layer with pervasive palagonite alteration. In direct contact with no evidence of reworking, pedogenesis or remobilization, the maar-forming sequence starts with parallel-stratified fall layers of altered basaltic pumice and scoria, with lava and limestone lithic clasts. This fall deposit marks the influx of xenocrystals and xenoliths, widely documented in previous works; they comprise mainly kaersutite mega crystals and spinel lherzolite respectively. The proximal fall deposit is divided into two thick layers by an indurated ash-tuff bed with pellets and single-rimmed accretionary lapilli. The upper layer of this fall deposit passes gradually onto an alternation of lapilli-sized layers with parallel ash-tuff horizons until it grades into cross-stratified, lithic-rich lapilli-tuff. The heterolithologic lapilli tuff is cemented on a fine ash matrix with palagonized juvenile clasts and abundant lava, shale and limestone lithics exhibiting a plethora of lithofacies in the like of parallel-bedded tuff, low-angle cross-bedded tuff and massive strata. This passes gradually

    Full Text Available Las actas capitulares del Cabildo de San Luis, actual provincia de la República Argentina, constituyen un valioso conjunto documental donde se refleja gran parte de las circunstancias históricas vividas por esta jurisdicción en el pasaje del Estado colonial al independiente. Es nuestra intención sumarnos al esfuerzo para construir una historia local basada en documentos y en nuevas perspectivas de análisis histórico. En este caso pretendemos identificar y analizar el uso del término “independencia” en las actas capitulares entre 1810 y 1820 partiendo de los aportes realizados por José Carlos Chiaramonte, quien considera que la Crisis de la Monarquía Española originó la emergencia de un conjunto de pueblos soberanos en el ex Virreinato del Río de la Plata. Con el correr de los años, estos pueblos, entre los que se encontraba San Luis, discutieron la forma de organizarse en una nueva entidad política para lo cual era indispensable definir un vínculo entre ellos y declarar la independencia como un paso fundamental hacia la construcción de un eventual nuevo Estado. Así es posible identificar el término “independencia civil” como una expresión que asemejamos a autonomía política, frente al término “independencia” que coincide con nuestro actual concepto vinculado con la ruptura de los lazos de dependencia con la Corona española. / The chapter acts of the Cabildo of San Luis constitute a valuable set of documents that reflect the historical circumstances experienced by this jurisdiction in the passage from a colonial state to an independent state.

    Full Text Available Las acciones y omisiones del presente en materia de política forestal pueden clarificarse si se revisan los antecedentes históricos. Por ello, el objetivo de esta investigación fue analizar la influencia del contexto internacional sobre las políticas forestales implementadas durante el régimen de Porfirio Díaz. Se amplía el panorama sobre las de uso y conservación de los bosques, así como sus repercusiones en San Luis Potosí. Para contextualizar los procesos mencionados, se realizó una consulta exhaustiva de documentos históricos y bibliográficos, y se encontró que el entorno internacional incentivó la creación de leyes e instituciones federales y locales para regular la explotación, el manejo y la conservación de los bosques. A pesar de ello, en esta entidad hubo una reducción importante en sus superficies boscosas; además, el gobierno federal y estatal no evidenció un interés por preservarlas. _______________ Current actions and omissions in forest policy can be clarified if the historical background is reviewed. Therefore, the objective of this research is to analyze the influence of the international context on forest policies implemented during the regime of Porfirio Diaz (1876-1911. In particular, it aims to broaden the outlook on government policies created for the management, use and conservation of forests and their impacts on San Luis Potosi. A thorough consultation of historical and bibliographical documents was made to understand the historical processes. It was found that the international environment encouraged the creation of laws, regulations and federal and local institutions for the purpose of regulating the exploitation, management and conservation of forests. However, the state of San Luis Potosi experienced a significant reduction in their forest areas; in addition, the federal and state governments showed no interest in applying conservation of forests in Potosi territory.

    2001-01-01

    Virtually the entire Rocky Mountain population (RMP) of greater sandhill cranes uses the San Luis Valley (SLV) of Colorado as a spring stopover area. RMP cranes in the SLV depend on unharvested grain provided on Monte Vista National Wildlife Refuge, and on waste grain in privately owned fields. In recent years, however, fall tillage and irrigation of grain fields has become increasingly widespread in the SLV. These changes in farming practices have resulted in an unmeasured reduction in waste grain availability for RMP cranes during spring and have prompted concern over whether current or projected foods are adequate to meet spring demands of the target population size of 18,000-20,000 RMP cranesa?|

    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.

  16. Potential field studies of the central San Luis Basin and San Juan Mountains, Colorado and New Mexico, and southern and western Afghanistan

    Drenth, Benjamin John

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

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

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

    To identify, from the perspective of the health staff, the strengths and weaknesses of the program for the detection and control of cervical cancer through a qualitative assessment implemented in three health centers in the city of San Luis Potosi, Mexico, from August 2008 to November 2009. A qualitative evaluation was performed. Nine providers participated in the study. The providers were selected by purposeful sampling using a voluntary participation criterion. Initially, information on the characteristics and the context in which the program operates was obtained from the health centers. Later, 18 semi-structured interviews were conducted with nine informants to probe their perspective. A directed content analysis was used. The strengths reported by staff were the fact that the program is free of charge, the availability of material resources, and the strategies that helped encourage the recruitment of women and their access to screening. The main weaknesses consisted of limitations in human resources and physical infrastructure, inefficient organization of activities, the staff's poor technical training, limited promotion of activities, and limitations in monitoring women with positive results. This study reveals the need for increased human resources, changes in regulations and reorganization of the program's actions in some health centers to ensure the quality of the service, meet women's needs, and promote coverage in all the program's actions.

    2016-01-01

    Knowledge of the factors affecting the vigor of desert riparian trees is important for their conservation and management. I used multiple regression to assess effects of streamflow and climate (12–14 years of data) or climate alone (up to 60 years of data) on radial growth of clonal narrowleaf cottonwood (Populus angustifolia), a foundation species in the arid, Closed Basin portion of the San Luis Valley, Colorado. I collected increment cores from trees (14–90 cm DBH) at four sites along each of Sand and Deadman creeks (total N = 85), including both perennial and ephemeral reaches. Analyses on trees Drought Severity Index) coincided with dramatically reduced radial growth. Each shift was presumably associated with branch dieback that produced a legacy effect apparent in many SGI series: uncharacteristically low SGI in the year following the shift. My results suggest trees in locations distant from the active channel rely on the regional shallow unconfined aquifer, summer rainfall, or both to meet water demands. The landscape-level differences in the water supplies sustaining these trees imply variable effects from shifts in winter-versus monsoon-related precipitation, and from climate change versus streamflow or groundwater management.

    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 Mexicans residing in the Monterrey metropolitan area in Nuevo León, Mexico, were grouped by generation and birthplace [Monterrey Metropolitan Area (MMA), San Luis Potosi (SLP), and Zacatecas (ZAC)] of the four grandparents to determine the extent of genetic variation within this population and the genetic differences, if any, between the natives living in the MMA and the immigrant populations from SLP and ZAC. Nine genetic marker systems were analyzed. The genetic distance analysis indicates that SLP and ZAC are similar to the MMA, irrespective of birthplace and generation. Gene diversity analysis (GST) suggests that more than 96% of the total gene diversity (HT) can be attributed to individual variation within the population. The genetic admixture analysis suggests that the Mexicans of the MMA, SLP, and ZAC, stratified by birthplace and generation, have received a predominantly Spanish contribution (78.5%), followed by a Mexican Indian contribution (21.5%). Similarly, admixture analysis, conducted on the population of Nuevo León and stratified by generation, indicates a substantial contribution from the MMA (64.6%), followed by ZAC (22.1%) and SLP (13.3%). Finally, we demonstrate that there is no nonrandom association of alleles among the genetic marker systems (i.e., no evidence of gametic disequilibrium) despite the Mestizo origin of this population.

    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.

    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.

    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.

    The places where a child lives and attends to school are both major environmental and social determinants of its present and future health status. Noncommunicable diseases (NCDs) and some of their risk factors among child and adolescent populations are obesity and dyslipidemia, so finding the patterns of distribution of these risk factors by gender, type of school, area, and margination level is important to do health intervention focusing in their necessities to prevent diseases at younger ages. Because of that, a cross-sectional study was performed among elementary and junior high school students from public and private schools in six of the seven areas of the metropolitan zone of San Luis Potosi, Mexico. Biochemical dyslipidemia indicators (triglycerides, total cholesterol, and high-density lipoprotein) and anthropometric data (weight and height) were obtained. Seventeen public schools and five private schools with a total of 383 students were included. More than half of the studied population (53.0%) had elevated triglyceride levels. A total of 330 students (86.2%) had normal levels of total cholesterol with a mean value of 141.7 mg/dl, and 202 schoolchildren (52.8%) had lower than acceptable levels of high-density lipoprotein (HDL) with a mean value of 43.9 mg/dl. There were differences in the levels of high-density protein between the areas and the type of school where they had been studied. Finally, a total of 150 students (39.4%) had at least one altered lipid value and 103 participants (26.9%) had two altered values. Several students, despite their young age, showed a high prevalence of risk factors, so it is important to design programs according to their necessities.

    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.

    Executive SummaryWe surveyed for Least Bell’s Vireos (LBVI) (Vireo bellii pusillus) and Southwestern Willow Flycatchers (SWFL) (Empidonax traillii extimus) along the San Luis Rey River, between College Boulevard in Oceanside and Interstate 15 in Fallbrook, California (middle San Luis Rey River), in 2016. Surveys were done from March 30 to July 11 (LBVI) and from May 18 to July 30 (SWFL). We found 142 LBVI territories, at least 106 of which were occupied by pairs. Six additional transient LBVIs were detected. Of 20 banded LBVIs detected in the survey area, 9 had been given full color-band combinations prior to 2016, although we were unable to determine the exact color combination of 1 female LBVI. Seven other LBVIs with single (natal) federal bands were recaptured and banded in 2016. Four vireos with single dark blue federal bands indicating that they were banded as nestlings on the lower San Luis Rey River could not be recaptured for identification.Three SFWL territories were observed in the survey area in 2016. Two territories were occupied by pairs and one by a male of unknown breeding status. Both pairs attempted to nest at least once, and both pairs were successful, fledging three young each. Nesting began in early June and continued into July. Brown-Headed Cowbird (Molothrus ater) eggs were not observed in either nest. An additional 12 transient Willow Flycatchers of unknown subspecies were detected in 2016.Two of the five resident SWFLs were originally banded as nestlings on Marine Corps Base Camp Pendleton. One male and one female were banded as nestlings on Camp Pendleton in 2009 and 2011, respectively. One natal male of unknown breeding status, originally banded as a nestling on the middle San Luis Rey River in 2015, was recaptured and given a unique color combination in 2016. This male was later detected on Marine Corps Base Camp Pendleton.

    This paper introduces a collection of four articles describing the San Luis Basin Sustainability Metrics Project. The Project developed a methodology for evaluating regional sustainability. This introduction provides the necessary background information for the project, description of the region, overview of the methods, and summary of the results. Although there are a multitude of scientifically based sustainability metrics, many are data intensive, difficult to calculate, and fail to capture all aspects of a system. We wanted to see if we could develop an approach that decision-makers could use to understand if their system was moving toward or away from sustainability. The goal was to produce a scientifically defensible, but straightforward and inexpensive methodology to measure and monitor environmental quality within a regional system. We initiated an interdisciplinary pilot project in the San Luis Basin, south-central Colorado, to test the methodology. The objectives were: 1) determine the applicability of using existing datasets to estimate metrics of sustainability at a regional scale; 2) calculate metrics through time from 1980 to 2005; and 3) compare and contrast the results to determine if the system was moving toward or away from sustainability. The sustainability metrics, chosen to represent major components of the system, were: 1) Ecological Footprint to capture the impact and human burden on the system; 2) Green Net Regional Product to represent economic welfare; 3) Emergy to capture the quality-normalized flow of energy through the system; and 4) Fisher information to capture the overall dynamic order and to look for possible regime changes. The methodology, data, and results of each metric are presented in the remaining four papers of the special collection. Based on the results of each metric and our criteria for understanding the sustainability trends, we find that the San Luis Basin is moving away from sustainability. Although we understand

    2014-12-01

    A measurement of hydraulic head in the aquifer is a critical metric needed for effective water management. Here we report on the use of InSAR data to inform groundwater management in the San Luis Valley (SLV), Colorado. We selected the SLV for study, as it is an important agricultural area struggling with groundwater management after a period of extreme drought. The techniques developed here can also be used to assist groundwater management in other agricultural areas, such as California's Central Valley. Reeves at al. (2013) analyzed 30 C-band ERS scenes over the SLV between 1992 and 2000 using the small baseline subset method (SBAS). They concluded that InSAR data can be used to calibrate the subsidence-to-head relationship and temporally extend hydraulic head measurements. To study the extent to which InSAR deformation time series can be used to interpolate spatial gaps in the well-based head measurements, we need to derive an InSAR ground deformation map due to groundwater extraction over the entire SLV. A major error source of InSAR data is highly variable temporal decorrelation over agricultural areas such as the SLV, which limits the number of InSAR pixels that can be selected for the SBAS analysis. Because L-band spaceborne radar systems such as ALOS PALSAR suffer less from temporal decorrelation than C-band and X-band spaceborne radar systems, we processed 92 small baseline interferograms using 17 ALOS scenes acquired between January 2007 and March 2011. We further employed an SBAS ground deformation model to represent surface subsidence due to groundwater extraction, which consists of a seasonal deformation superimposed on a linear trend. We observed that the long-term subsidence rate is smaller than 5 mm/year over the entire SLV and the magnitude of the seasonal subsidence can be up to 2 cm. Our results indicate that there is no severe long-term water storage loss in the confined aquifer at the SLV, consistent with previous C-band InSAR study (Reeves at

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

    2010-01-01

    Full Text Available La población humana actual de Argentina y de Latinoamérica en general es el resultado de cinco siglos de contacto entre los nativos americanos y las poblaciones migrantes, principalmente de Europa y Africa. En estudios llevados a cabo previamente por nuestro grupo en el Museo de Antropología de la Universidad Nacional de Córdoba, se determinó en 13 poblaciones rurales de Córdoba y San Luis que aproximadamente el 80% de los genomas mitocondriales analizados eran de origen amerindio. En el presente trabajo nos propusimos determinar la procedencia continental de los linajes maternos en aquellos individuos que no presentaron haplogrupos amerindios. Para ello se analizó el ADN de 98 individuos por PCR-RFLP en dos marcadores mitocondriales que sirven de diagnóstico de origen étnico-geográfico. Los resultados indican que en las muestras poblacionales de Córdoba existe en promedio, un 16% de haplogrupos europeos y un 8% de linajes africanos, mientras que en San Luis la incidencia es de 9% y 3%, respectivamente.

  19. Composition of Magmas, Minerals, and Melts of Tuffs and Lavas from the San Luis Caldera Complex, Colorado: Framework for Crystal Recycling and Melt Extraction Processes

    Science.gov (United States)

    Streck, M. J.; Lipman, P. W.

    2007-12-01

    The stratigraphy of the Oligocene San Luis Caldera Complex comprises three voluminous tuffs issued from overlapping calderas and numerous, compositionally diverse pre- and post-caldera lavas. The entire complex was erupted over an amazingly short period of 50-100 k.y. From oldest to youngest, the tuffs are the Rat Creek Tuff (>150 km3) that ranges in bulk composition from dacite to rhyolite to high-silica rhyolite, the dacitic Cebolla Creek Tuff (>250 km3), and the Nelson Mountain Tuff (>500 km3) that is again compositionally zoned from dacite to high-silica rhyolite. Pre- and post-caldera lavas range in composition from andesite to high-silica rhyolite. Phenocryst contents of most units range from 15 to 25%; only high-silica rhyolites are notably crystal-poorer (?5%) and tuffs can reach crystal contents of 35-45%. The compositional and lithological framework of the San Luis Caldera complex combined with the tight temporal and spatial control provide an ideal field laboratory for investigating whether minerals in younger volcanic units may be in part derived from recycling crystals of non-erupted magma of older units and for investigating generation processes of crystal-poor high-silica rhyolites. Many eruptive units are distinct on the level of bulk rock in terms of major and trace elemental composition and/or mineral proportions. For example, the dacitic to rhyolitic Rat Creek and Nelson Mountain Tuffs are dominated by pyroxene with only minor amphibole while the intervening dacitic Cebolla Creek Tuff contains abundant amphibole with subordinate pyroxene. When glass and mineral compositions are considered, eruptive units are less distinctive and observed compositions of individual units may cluster tightly or spread over most of the observed range for all units but in either case individual units typically follow broad compositional trends defined by all units. Interstitial melts of andesites to rhyolite are rhyodacitic to high-silca rhyolite.

    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.

  3. Latest Miocene-earliest Pliocene evolution of the ancestral Rio Grande at the Española-San Luis Basin boundary, northern New Mexico

    We use stratigraphic relations, paleoflow data, and 40Ar/39Ar dating to interpret net aggradation, punctuated by at least two minor incisional events, along part of the upper ancestral Rio Grande fluvial system between 5.5 and 4.5 Ma (in northern New Mexico). The studied fluvial deposits, which we informally call the Sandlin unit of the Santa Fe Group, overlie a structural high between the San Luis and Española Basins. The Sandlin unit was deposited by two merging, west- to southwest-flowing, ancestral Rio Grande tributaries respectively sourced in the central Taos Mountains and southern Taos Mountains-northeastern Picuris Mountains. The river confluence progressively shifted southwestward (downstream) with time, and the integrated river (ancestral Rio Grande) flowed southwards into the Española Basin to merge with the ancestral Rio Chama. Just prior to the end of the Miocene, this fluvial system was incised in the southern part of the study area (resulting in an approximately 4–7 km wide paleovalley), and had sufficient competency to transport cobbles and boulders. Sometime between emplacement of two basalt flows dated at 5.54± 0.38 Ma and 4.82±0.20 Ma (groundmass 40Ar/39Ar ages), this fluvial system deposited 10–12 m of sandier sediment (lower Sandlin subunit) preserved in the northern part of this paleovalley. The fluvial system widened between 4.82±0.20 and 4.50±0.07 Ma, depositing coarse sand and fine gravel up to 14 km north of the present-day Rio Grande. This 10–25 m-thick sediment package (upper Sandlin unit) buried earlier south- to southeast-trending paleovalleys (500–800 m wide) inferred from aeromagnetic data. Two brief incisional events are recognized. The first was caused by the 4.82±0.20 Ma basalt flow impounding south-flowing paleodrainages, and the second occurred shortly after emplacement of a 4.69±0.09 Ma basalt flow in the northern study area. Drivers responsible for Sandlin unit aggradation may include climate

  5. Opportunities for Open Automated Demand Response in Wastewater Treatment Facilities in California - Phase II Report. San Luis Rey Wastewater Treatment Plant Case Study

    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.

Ante este escenario indefinido, los militares transgredieron el orden al iniciar un pronunciamiento para externar su inconformidad. El gobierno general intervino en la vida política interna de los potosinos al ordenar a una facción del ejército regular de la federación que sofocara a los pronunciados. El movimiento político tomó otra dimensión y los sublevados redactaron un Plan político en contra del presidente Benito Juárez y sus ministros. El movimiento se mantuvo vigente al iniciar 1870 así el gobierno general envió a San Luis Potosí al general Mariano Escobedo con el propósito de restablecer a las autoridades legítimas.

    2015-01-01

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

    This study aims to describe the medical itineraries followed by breast cancer women affiliated to the People's Health Insurance in San Luis Potosí, central Mexico. We used an ethnographic approach based on oral histories of 12 women diagnosed with breast cancer in the year prior to the first meeting. Two face-to-face sessions per participant lasting 60 minutes each were conducted followed by a telephone interview. Content and diachronic analyses were used. Three main itineraries were identified: (1) diagnostic process, (2) final diagnosis to treatment, and (3) cancer control and relapse. Findings suggested that infrastructure and human resources to adequately screen and timely diagnose breast cancer were scant and insufficiently trained, respectively. Deferral of medical assessment was related with lack of information about breast cancer consequences, with women being afraid of a positive result, and with economic constraints. The current screening program needs to be redesigned to prevent diagnostic delays, as these seem to explain the high frequency of advanced stages reported at the time of diagnosis.

    Full Text Available Resumen: La violencia contra las mujeres es un problema mundial, dado el impacto que tiene en la calidad de vida de quienes la viven, bajo la complicidad de una cultura patriarcal y un Estado que la invisibiliza. Este artículo busca hacer visibles los contextos de violencia en que viven mujeres "parejas de migrantes" en las localidades de origen, problematizando cómo atentan contra su salud física y mental. Se trató de un estudio cualitativo con enfoque en la antropología interpretativa, con 21 mujeres de localidades rurales y urbanas de San Luis Potosí, México; se aplicaron entrevistas desde el marco de historia de la vida cotidiana y análisis de discurso. Los resultados muestran que las mujeres viven mayor violencia cuando sus parejas migran, nuevas formas de violencia se cometen contra ellas, y los ámbitos en que la sufren incluyen el doméstico y el comunitario. La violencia contra las mujeres constituye un problema de salud pública que debe atenderse desde un marco sensible a las dinámicas sociales y culturales que caracterizan los contextos en que se aplican los programas de salud.

    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. 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. 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. 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 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.

    Full Text Available Pollution and global warming is an issue that has great social impact, addressing the emission of Green-House Gases (GHG from different angles, as in the case of the livestock sector while contributing to global warming may also help mitigate the effect of these gases, reducing the carbon footprint of their products.Argentina integral Nations Framework Convention on Climate Change (Law No. 24.295, with the signing ofthe Kyoto Protocol (Law No. 25.438 assumed the responsibility for reducing GHG emissions, among otherobligations. The latest reports to the Convention United Nations Framework on Climate Change (UNFCCC,show that emissions from the Argentine agricultural sector represent approximately 50% of total GHGs, whichmore than 35% is methane, almost exclusively the product of enteric fermentation in cattle. However, a criticalanalysis of such inventories, it is appropriate to improve in the source data base, integrating not only the animalcategories, but also with production systems and offers fodder, avoiding the use of default factors proposedby the Intergovernmental Panel on Climate Change (IPCC. In this context, the objectives of this study wereto obtain better data quality of the livestock involved in the preparation of national inventories, thus, estimatedenteric methane emissions, through a detailed characterization of systems for beef and San Luis. Using theIPCC Tier II methodology, the emission of CH4 from enteric systems of beef production in the province for 2009 was 2.128,82 Gg CO2eq. (Gg carbon dioxide equivalent. While the contribution to the total emission is low, the province will mean a social cost of 13,04 kg CO2eq./kg meat, aggravated by the trend of recent years the increase in cattle stock. On this basis, the need for strategic changes in production systems, turning the meat chain in the province that is environmentally sustainable, socially and economically.

    Full Text Available El texto analiza las significaciones y prácticas corporales desarrolladas por estudiantes de secundarias públicas en la ciudad de San Luis Potosí. El objetivo es examinar las construcciones de significados y vivencias en torno al cuerpo en función de dos ejes: 1 las relaciones de identidad y las percepciones sobre la diferencia cultural y 2 las relaciones de género y sexualidad. La escuela enseña y transmite esquemas de pensamiento y acción socialmente dominantes, que se expresan en el cuerpo y orientan las relaciones entre hombres y mujeres. A partir de testimonios expresa- dos por estudiantes en entrevistas colectivas, se identifica que la escuela no sólo es un ámbito de transmisión y reproducción, sino también es un espacio en donde los agentes escolares generan y socializan modelos referentes al cuerpo y sus acciones. De esta manera los/as estudiantes construyen su identidad mediante representaciones del cuerpo y de la diversidad cultural. Se concluye que el cuerpo rebasa los temas mera- mente biológicos impartidos en la escuela a la vez que no se reduce a los aspectos sexuales, sino que en él se internalizan y objetivan los principios normativos y de jerarquía, de desigualdad, de transgresión, de dife- renciación cultural y de poder al interior de un campo socia

    The San Luis Valley (SLV)–Taos Plateau study area in south-central Colorado and north-central New Mexico is a large alpine valley surrounded by mountains with an area of approximately 6,263,000 acres (25,345 km2) (Figure ES.1-1). This area receives ample sunshine throughout the year, making it an ideal location for solar energy generation, and there are currently five photovoltaic facilities operating on private lands in the SLV, ranging in capacity from 1 to 30 megawatt (MW). In 2012 the Bureau of Land Management (BLM) launched its Solar Energy Program, which included the identification of four solar energy zones (SEZs) in the SLV totaling 16,308 acres (66 km2), as well as over 50,000 (202 km2) acres of other BLM-administered lands potentially available for application for solar development. The SEZ areas, named Antonito Southeast, De Tilla Gulch, Fourmile East, and Los Mogotes East, were defined by the BLM as areas well-suited for utility-scale (i.e., larger than 20 MW) production of solar energy where solar energy development would be prioritized (BLM 2012). Nonetheless, it was recognized that solar development in the SEZs would result in some unavoidable adverse impacts, and so the BLM initiated a solar regional mitigation strategy (SRMS) study for three of the SEZs (BLM and Argonne 2016). The SRMS is designed to identify residual impacts of solar development in the SEZs (that is, those that cannot be avoided or minimized onsite), identify those residual impacts that warrant compensatory mitigation when considering the regional status and trends of the resources, identify appropriate regional compensatory mitigation locations and actions to address those residual impacts, and recommend appropriate fees to implement those compensatory mitigation measures.

  4. El Morro caldera (33° 10‧ S, 66° 24‧ W), San Luis, Argentina: An exceptional case of fossil pre-collapse updoming

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

    Full Text Available Mother and child mortality reflects the level of social and economic development of a country; therefore, reproductive health is a sanitary priority. Mortality prevention depends directly on the coverage and quality of health services. Objective: to assess the compliance of prenatal care with the NOM 007 norm and its correlation with maternal morbidity in a health center located in San Luis Potosí, Mexico. Methodology: a descriptive, correlational, and quantitative study in which the units of analysis were the medical records of 571 pregnant women cared for during 2008. In order to prove the hypothesis, Pearson’s r was used. The p value was ≤ 0.05. Results: ages ranged from 13 to 43 years. Additionally, 37.1% of the patients were teenagers and 44.3 % began receiving attention during the second trimester of their pregnancy; 38.2 % attended at least five medical appointments, and 46.4 % had morbidity. For the latter group, urinary infection was the most common condition (224 cases. Prenatal attention was adequate in 2.6 % of the cases according to the actions performed. Health promotion actions were the least frequent. Conclusion: the level of compliance with the NOM 007 norm for prenatal care was considered inadequate in 97.4 % of the cases and was consistent with maternal morbidity (87.5-100 %. This could be related to more frequent appointments for some women and with late treatment, which resulted in less time to perform said actions. Contrary to expectations, greater compliance meant higher maternal morbidity (r = 0.318, p < 0.000.

    Full Text Available La cuenca de la quebrada San Luis es una pequeña cuenca experimental ubicada en la zona urbana de la ciudad de Manizales, típica de media montaña de la zona andina colombiana, que se encuentra muy bien instrumentada pues cuenta con cuatro estaciones pluviográficas y una de aforo dentro de ella para un área aproximada de 1,0 km². La información temporal se unificó para tenerla disponible a intervalos de 5 minutos. Este trabajo pretende estimar los tiempos de concentración y de rezago de la cuenca a partir de la información disponible en los hidrogramas y hietogramas registrados, para compararlos con los valores estimados mediante las ecuaciones empíricas disponibles en la literatura. Las principales conclusiones destacan que la ecuación empírica del tiempo de concentración que muestra un mejor ajuste a la observada en la cuenca experimental es el valor de la mediana de todas las ecuaciones, siendo las ecuaciones de Kirpich, Passini, California y VenturaHeras las que muestran valores más conservadores para el diseño hidrológico, ya que muestran respuestas más rápidas a las observadas. En cuanto al tiempo de rezago, se observa una relación aproximada de 0.6 con respecto al tiempo de concentración medio estimado.

    2010-01-01

    A statistical evaluation of shaking damage to wood-framed houses caused by the 2003 M6.5 San Simeon earthquake indicates that both the rate and severity of damage, independent of structure type, are significantly greater on hilltops compared to hill slopes when underlain by Cretaceous or Tertiary sedimentary rocks. This increase in damage is interpreted to be the result of topographic amplification. An increase in the damage rate is found for all structures built on Plio-Pleistocene rocks independent of topographic position, and this is interpreted to be the result of amplified shaking caused by geologic site response. Damage rate and severity to houses built on Tertiary rocks suggest that amplification due to both topographic position and geologic site response may be occurring in these rocks, but effects from other topographic parameters cannot be ruled out. For all geologic and topographic conditions, houses with raised foundations are more frequently damaged than those with slab foundations. However, the severity of damage to houses on raised foundations is only significantly greater for those on hill slopes underlain by Tertiary rocks. Structures with some damage-resistant characteristics experienced greater damage severity on hilltops, suggesting a spectral response to topographic amplification. ?? 2010, Earthquake Engineering Research Institute.

Damage rate and severity to houses built on Tertiary rocks suggest that amplification due to both topographic position and geologic site response may be occurring in these rocks, but effects from other topographic parameters cannot be ruled out. In particular, higher slope curvature on hilltops, a characteristic feature of hills and ridges underlain by Tertiary rocks, also correlates with higher damage frequency. For all geologic and topographic conditions, houses with raised foundations are more frequently damaged than those with slab foundations. However, the severity of damage to houses on raised foundations is only significantly greater for those on hill slopes underlain by Tertiary rocks. Structures with some damage-resistant characteristics experienced greater damage severity on hilltops, suggesting a spectral response to topographic amplification.

    This article presents an analysis of the turbidity and solid contents in suspension of the runoff that might be used for artificially recharging a deep granular aquifer located by San Luis de Potosi. The programmed artificial recharge operation corresponds to a type known as Aquifer Storage and Recovery (ASR). A series of equations to correlate the solids in suspension with turbidity and its validity are put forth. Reference is also made to the maximum content in suspended solids that operations of USR-type recharge can assume. Through this analysis, we were able to corroborate that turbidity varies over time according to an exponential function of the decreasing type, which accounts both for the deposition of particles that sediment exclusively due to the effect of gravity, and the action of certain mechanisms that favour coagulation and the natural flocculation of colloidal particles. Given that the operations of artificial recharge by means of USR require very rigorous conditions, in terms of the maximum contents of solids in suspension, the analysis has also been carried out for surface installations such as infiltration ponds.

    The San Luis Basin segment of the northern Rio Grande rift, straddling the Colorado-New Mexico border, is an asymmetrical graben where the major basin-bounding fault is on the east side. In contrast, the west side is a basin-directed dip slope surface cut by north to northwest trending faults with predominantly down-to-southwest displacement. Around 26 Ma, initial rift-related faulting formed broad, shallow basins coincident with basaltic volcanism of the Hinsdale Formation. Later episodes of rifting produced deep and narrow sub-basins generally along the eastern boundary. Basin-fill deposits along the western margin are generally thin. However, in the northern Tusas Mountains, gravity data identifies a small, yet deep, sub-basin that may contain 750 m of basin-filling Los Pinos Formation based on thickness projections derived from mapping. The Los Pinos Formation is overlain by early rift-related Hinsdale Formation basalt flows indicating this sub-basin formed as part of early rifting; the sub-basin may be a southern extension of the Monte Vista graben to the north. The stratigraphic section along the western boundary includes Precambrian basement up to volcanic rocks of the Taos Plateau volcanic field (~5-2Ma). Dips on the early-rift Miocene to Oligocene Hinsdale Formation lavas (3-5 degrees) reflect the cumulative eastward tilting corresponding to continued basin subsidence. Shallower dips (1-2 degrees) on early Pliocene volcanic rocks suggest continued subsidence up to about 3 Ma, or younger. Down-to-southwest faults accommodating eastward tilting are mostly in areas west of Pliocene volcanic rocks; individual faults offset Hinsdale Formation and older rocks by up to 200 m. The few observed faults in the Pliocene volcanic rocks have minor offset. Numerous volcanic vents are in close proximity to the faults along the western boundary. Volcanoes are commonly low to medium relief shield volcanoes with basaltic andesite composition capped by late stage cinder cones

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

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

    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.

Por lo anterior, el objetivo de este estudio fue analizar la distribución geográfica de las aves en la zona para identificar las áreas con mayor concentración de la riqueza y evaluar su estado actual de conservación para fundamentar la necesidad de incrementar la superficie dedicada a las áreas naturales protegidas en el futuro. Se recolectó información proveniente de diversas bases de datos de colecciones y museos, además de realizar trabajo de campo en el periodo de enero 2009 a Mayo 2011. Se modelaron las distribuciones potenciales para 284 especies con el programa GARP y se elaboró un mapa de consenso para determinar la ubicación espacial de las áreas con condiciones ambientales para soportar el mayor número de especies. Finalmente, se evaluó la representatividad de las zonas dedicadas a la conservación para las aves. Se registraron 357 especies, de las cuales el 71.4% son residentes permanentes, 19% son migratorias de invierno y 3.9% residentes de verano. Del total, 41 especies son endémicas y 48 se encuentran en alguna categoría de riesgo; la mayor concentración de especies se presentó en las coberturas de bosques de encino, bosques mesófilos y selvas medianas y bajas caducifolias, en un intervalo altitudinal entre 100-1 500m con una más alta cantidad de nichos en la parte centro y hacia el sur y este de la región.

    Transient electromagnetic (TEM) soundings were made in the San Luis Valley, Colorado, to map the location of a blue clay unit as well as to investigate the presence of suspected faults. A total of 147 soundings were made near and in Great Sand Dunes National Park and Preserve, and an additional 6 soundings were made near Hansen Bluff on the eastern edge of the Alamosa National Wildlife Refuge. The blue clay is a significant hydrologic feature in the area that separates an unconfined surface aquifer from a deeper confined aquifer. Knowledge of its location is important to regional hydrological models. Previous analysis of well logs has shown that the blue clay has a resistivity of 10 ohm-meters or less, which is in contrast to the higher resistivity of sand, gravel, and other clay units found in the area, making it a very good target for TEM soundings. The top of the blue clay was found to have considerable relief, suggesting the possibility of deformation of the clay during or after deposition. Because of rift activity, deformation is to be expected. Of the TEM profiles made across faults identified by aeromagnetic data, some showed resistivity variations and (or) subsurface elevation relief of resistivity units, suggestive of faulting. Such patterns were not associated with all suspected faults. The Hansen Bluff profile showed variations in resistivity and depth to conductor that coincide with a scarp between the highlands to the east and the floodplain of the Rio Grande to the west.

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.

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

    Full Text Available La región de la Sierra Madre Oriental (SMO en el estado de San Luis Potosí en México es considerada un sitio de relevancia para la conservación de la avifauna a nivel nacional. Por lo anterior, el objetivo de este estudio fue analizar la distribución geográfica de las aves en la zona para identificar las áreas con mayor concentración de la riqueza y evaluar su estado actual de conservación para fundamentar la necesidad de incrementar la superficie dedicada a las áreas naturales protegidas en el futuro. Se recolectó información proveniente de diversas bases de datos de colecciones y museos, además de realizar trabajo de campo en el periodo de enero 2009 a Mayo 2011. Se modelaron las distribuciones potenciales para 284 especies con el programa GARP y se elaboró un mapa de consenso para determinar la ubicación espacial de las áreas con condiciones ambientales para soportar el mayor número de especies. Finalmente, se evaluó la representatividad de las zonas dedicadas a la conservación para las aves. Se registraron 357 especies, de las cuales el 71.4% son residentes permanentes, 19% son migratorias de invierno y 3.9% residentes de verano. Del total, 41 especies son endémicas y 48 se encuentran en alguna categoría de riesgo; la mayor concentración de especies se presentó en las coberturas de bosques de encino, bosques mesófilos y selvas medianas y bajas caducifolias, en un intervalo altitudinal entre 100-1 500m con una más alta cantidad de nichos en la parte centro y hacia el sur y este de la región. Sólo el 10% de las zonas con alto potencial de número de especies está incluido como área de importancia para la conservación de las aves y el 3% del total de áreas potenciales está bajo alguna categoría estatal de protección; sin embargo, ninguna de las áreas tiene un plan de manejo que esté siendo aplicado y monitoreado.

    Full Text Available Con el fin de caracterizar el riesgo ambiental de un sitio contaminado en México, que se localizaen un distrito minero del estado de San Luis Potosí, se construyó su modelo conceptual. El sitio presenta niveles altos de plomo y arsénico en medios ambientales por la dispersión ambiental de residuos y emisiones de la actividad minera histórica y del presente. En la elaboración del modelo, se utilizaron procedimientos sistemáticos aprobados por la normatividad internacional e información histórica del sitio sobre contaminación, impacto y riesgo ambiental para el periodo 1995-2008. El modelo sirvió para 1 establecer conexiones Fuente-Ruta-Receptor, 2 detectar zonas donde ocurren rutas completas de exposición al arsénico y al plomo, y 3 confirmar zonas de mayor riesgo susceptibles de aplicar criterios de remediación de suelos contaminados conforme a la normatividad mexicana. Según indica el estudio, la zona de mayor potencial de riesgo corresponde a la nombrada como Villa de la Paz, destacando al arsénico como el problema principal. Modelos conceptuales en sitios mineros contaminados de EE.UU., Portugal, Irlanda y Australia han servido como herramientas para describir fuentes potenciales, rutas y posibles receptores, realizar el proceso de evaluación de riesgo, y para evaluar la factibilidad de remediación del sitio, entre otros. La normatividad mexicana recomienda elaborar el modelo conceptual en estudios de evaluación de riesgo ambiental y para la remediación del sitio. No obstante, no existen casos documentados en revistas científicas sobre la construcción de estos modelos en sitios mineros de México. Uno de los beneficios potenciales del uso del modelo propuesto, es que, una vez que ha sido simplificada la información, puede ser una herramienta básica para el desarrollo de evaluaciones ambientales del sitio estudiado y una guía para la construcción de modelos en otros sitios mineros de México.

    Full Text Available El conocimiento de los patrones de distribución de especies en las comunidades vegetales y su relación con factores del medio es un objetivo fundamental en ecología. Las comunidades de Pinus cembroides y P. johannis coexisten en diversas regiones de México, pero P. cembroides tiende a distribuirse en laderas de exposiciones sur y suroeste en sitios deteriorados, a diferencia de P. johannis localizados en áreas mésicas en laderas con exposición norte y noreste. El objetivo de este trabajo fue analizar la influencia de algunos factores físicos en la semejanza florística de los piñonares de P. cembroides y P. johannis. El área de estudio se ubica en la Sierra San Miguelito, San Luis Potosí, México. Se seleccionaron 40 unidades de muestreo, distribuidas en una superficie de 50km²; en cada una se trazaron dos líneas de 20m perpendiculares entre sí, donde se registró la cobertura de los individuos interceptados. Se elaboraron dos tipos de matrices de datos: la primera con los valores de cobertura de 91 especies y la segunda, con siete variables topográficas, climáticas y de incidencia solar. Se aplicaron análisis de agrupamiento y de ordenación para explorar la influencia de variables ambientales en la diferenciación florística de los piñonares. El agrupamiento diferenció seis grupos; los tres primeros caracterizados por bosques de P. cembroides. La ordenación mostró que la varianza representada por los tres primeros ejes fue de 65.9%. El eje uno se correlacionó positivamente con la altitud y negativamente con la temperatura media anual y la orientación; los ejes dos y tres mostraron bajos valores de correlación con las variables probadas. Se observó que los piñonares de P. cembroides y flora acompañante, tienden a localizarse en sitios de menor altitud, con mayor temperatura media anual y en laderas con orientación al sur y suroeste. En contraste, los sitios de P. johannis, los de P. johannis-P. cembroides y de

    In this paper are designed an analyzed the control ties of a 300MW fossil unit at different operation levels. The design and analysis were developed on an operation range of 50% to 100% load. The main control ties were studied among which are the feedwater flow, the superheating zone temperatures and the generated output. The technique used for the design is the decomposition in singular values (DSV) of the plant transference matrix. This is a recent technique that permits finding the most important interactions among output-input variables, over a significative frequencies range for the transference matrix of the plant. For this purpose utilizes the control properties of the transference matrix, such as: control effort, output-input interaction and ruggedness with respect to uncertainties. The control structures obtained were tested in a digital model of a fossil plant unit. A comparison study of both structures (original and modified) showed enhancement in the performance of the power plant with modified structure. [Espanol] En este trabajo se disenan y analizan los lazos de control de una unidad termoelectrica de 300 MW, a diferentes niveles de operacion. El diseno y analisis se desarrollo sobre un rango de operacion de 50 a 100 por ciento de carga. Se estudiaron los principales lazos de control entre los que se encuentran el flujo de agua de alimentacion, las temperaturas de la zona de sobrecalentamiento y la potencia generada. La tecnica utilizada para el diseno es la descomposicion en valores singulares (DVS) de la matriz de transferencia de la planta. Esta es una tecnica reciente que permite encontrar las interacciones mas importantes entre variables entrada-salida, sobre un rango de frecuencias significativas para la matriz de transferencia de la planta. Utiliza para ello las propiedades de control de la matriz de transferencia, como son: esfuerzo de control, interaccion entrada-salida y robustez con respecto a incertidumbres.

    In this occasion, a methodology is presented that carries out an integral energy evaluation of fossil fuel power plants units (FFPPU) with the purpose of determining the root of the significant decrements of power produced soon after the annual maintenance service. This proposal, besides identifying the origin of the energy efficiency problems, offers information about the contributions of each one of the involved equipment in the total decrement of the unit. With this methodology, the maintenance focuses in the equipment that contributes to the greater energy loss. This document presents such methodology along with its application in a real case, results and necessary remedial actions, demonstrating that its application offers bases for the investment in corrective measures. [Spanish] En esta ocasion se presenta una metodologia que efectua una evaluacion energetica integral de las unidades de centrales termoelectricas (UCT) con el fin de determinar la raiz de los decrementos de potencia significativos producidos luego del servicio anual de mantenimiento.

    One of the potential areas for energy saving in Central Electric Power Plants are the auxiliaries system, so as to based in a preliminary energy diagnosis and considering that energy saving measures would be taken, going from the instrumentation, operational changes in equipment, as well as in using velocity variators in motors, it turns out to be that the energy consumption of auxiliaries at 75% load in a 150 MW thermal power plant varies from 3% to 4% and for the case of a 350 MW power plant the energy consumption of the auxiliaries represents 2 to 3.5%. Nowadays this consumption are above 6%. Considering that the country has 40 units with capacities varying from 150 to 350 MW, the economical and the fuel saving would be substantial. This paper will present a summary of the methodology to be used to carry out this type of projects. [Espanol] Una de las areas potenciales de ahorro de energia en centrales termoelectricas son los sistemas auxiliares, de tal manera que basados en un diagnostico energetico preliminar y considerando que se aplicarian las medidas de ahorro de energia que van desde la instrumentacion, cambios operativos en equipos, asi como el uso de variadores de velocidad en motores, se tienen que los consumos de auxiliares para un 75% de carga en una central termoelectrica de 150 MW varian desde un 3% hasta un 4% y para el caso de una central termoelectrica de 350 MW, el consumo de auxiliares representa del 2 al 3.5%. Hoy en dia dichos consumos estan por encima del 6%. Si consideramos que el pais cuenta con 40 unidades que varian desde 150 MW hasta 350 MW, entonces los ahorros economicos y de combustible serian impactantes. La presente ponencia mostrara un resumen de la metodologia a emplear para la realizacion de este tipo de proyectos.

    Full Text Available Em 1988, Beatriz Sarlo propõe uma passagem entre duas poéticas em Jorge Luis Borges: de Evaristo Carriego (1930 em direção a Historia universal de la infamia (1935. Os dois textos são “insidiosos”, defende a pesquisadora, porque falsificam as biografias de seus personagens. Porém, a coletânea de 1935 opera em âmbito universal. Este movimento, afirma Sarlo, é portador de um acumulo de prerrogativas, associado à dupla inscrição de Borges: o cidadão do mundo e, simultaneamente, o de um país pensado a partir de Buenos Aires. Neste ensaio, sugerimos uma passagem anterior, evidenciada em “Sentirse en muerte” (1928: do criollismo – o poeta dos arrabaldes, dotado da capacidade de transporte sensível e instalado nos limites de sua cidade imaginada, que busca a representação poética digna de seu conceito de argentinidade – em direção à prosa que alcança o caráter argumentativo-reflexivo dos ensaios sobre o tempo e a eternidade característicos de Borges, início de sua legitimação como “percibidor abstracto del mundo”. Este movimento é também portador de um acúmulo de prerrogativas, dupla inscrição de Borges: como poeta, literato e ensaísta programático do criollismo; como meditador dedicado aos assombros contidos em nossos conceitos de vida, tempo e universo, operador de textos da Filosofia e da Teologia.

    Full Text Available LUIS GUILLERMO VASCO URIBE, Maestro Universitario ya retirado de la Universidad Nacional de Colombia, es una de las figuras centrales de la antropología Colombiana. Su trayectoria en el campo se aproxima a los 40 años, a través de los cuales ha ejercido una antropología comprometida primordialmente con las luchas campesinas e indígenas, en particular de los pueblos guambiano, páez y embera chamí. Su postura marxista y maoísta radical, tanto en el ejercicio antropológico como pedagógico, le ha merecido la crítica de próximos y lejanos, aun cuando ha marcado indiscutiblemente toda una línea teórica y metodológica sobre la que hoy consideramos necesario reflexionar: ¿puede el antropólogo contemporáneo servir a la emancipación o es una indefectible pieza del engranaje del status quo? Como se planteó en la convocatoria para el presente número, si las relaciones entre "lo intelectual" y "lo político", en tanto un cuestionamiento a los usos y abusos del poder, se han transformado, ¿dónde podría "localizarse" esa conexión hoy día? ¿Cuál es el locus de la vocación crítica del investigador, del antropólogo y, en general, del académico? Y, en este contexto, ¿hacia dónde debe dirigirse la formación de las nuevas generaciones de antropólogos, en tanto que en la actual lógica del mercado se privilegian ciertas relaciones con el saber-poder que exaltan otras nociones sobre la ética y la práctica antropológica? Sea esta ocasión para hacer un reconocimiento al profesor Vasco, reproduciendo los apartes de una interpelación que le efectuó en 2003 la antropóloga francesa Elisabeth Cunin, investigadora sobre grupos negros en la Costa Atlántica colombiana. Estos fragmentos contienen vetas cardinales sobre la situación actual de la formación y el ejercicio de los antropólogos colombianos, a partir de la experiencia misma del profesor Vasco como antropólogo o quizás, al decir de muchos, como "anti-antropólogo"

    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

    Formulation and validation of a dispersion model for relative plumes are presented in this paper. This model (MOTTQUIP: Modelo de Transporte Turbulento y Quimico de Plumas) was developed to assess the environmental impact of power generation. The theoretical formulation if this model is based on the integral form of the mass balance equation. MOTTQUIP can simulate (in two dimensions) the turbulent dispersion and chemical transformation phenomena of a nitrogen oxides (Nox) non-buoyant plume in an ozone (O{sub 3}) atmosphere. The results produced by MOTTQUIP, however, can run in a personal computer consuming relatively short CPU times. [Spanish] En este trabajo se presentan la formulacion y la validacion de un modelo (MOTTQUIP: Modelo de Transporte Turbulento y Quimica de Plumas) para evaluar el impacto de las emisiones de contaminantes reactivos de centrales termoelectricas. Este modelo se formula a partir de la forma integral de la ecuacion de balance de masa, y no de su forma diferencial, como se procede generalmente. MOTTQUIP simula, en dos dimensiones, la dispersion turbulenta y transformacion quimica de una pluma no flotante de oxidos de nitrogeno (Nox), misma que se interna paulatinamente en un ambiente de ozono (O{sub 3}). Los resultados obtenidos son comparados con los de modelos alternos que simulan el mismo sistema reactivo, encontrandose una concordancia bastante aceptable. Una ventaja de MOTTQUIP, sin embargo, es que puede utilizarse en sistemas de computo pequenos, empleando tiempos de CPU relativamente cortos.

  5. Magnetic map of the Irish Hills and surrounding areas, San Luis Obispo County, central California

    2012-01-01

    A magnetic map of the Irish Hills and surrounding areas was created as part of a cooperative research and development agreement with the Pacific Gas and Electric Company and is intended to promote further understanding of the areal geology and structure by serving as a basis for geophysical interpretations and by supporting geological mapping, mineral and water resource investigations, and other topical studies. Local spatial variations in the Earth's magnetic field (evident as anomalies on magnetic maps) reflect the distribution of magnetic minerals, primarily magnetite, in the underlying rocks. In many cases the volume content of magnetic minerals can be related to rock type, and abrupt spatial changes in the amount of magnetic minerals can be related to either lithologic or structural boundaries. Magnetic susceptibility measurements from the area indicate that bodies of serpentinite and other mafic and ultramafic rocks tend to produce the most intense magnetic anomalies, but such generalizations must be applied with caution because some sedimentary units also can produce measurable magnetic anomalies. Remanent magnetization does not appear to be a significant source for magnetic anomalies because it is an order of magnitude less than the induced magnetization. The map is a mosaic of three separate surveys collected by (1) fixed-wing aircraft at a nominal height of 305 m, (2) by boat with the sensor at sea level, and (3) by helicopter. The helicopter survey was flown by New-Sense Geophysics in October 2009 along flight lines spaced 150-m apart and at a nominal terrain clearance of 50 to 100 m. Tie lines were flown 1,500-m apart. Data were adjusted for lag error and diurnal field variations. Further processing included microleveling using the tie lines and subtraction of the reference field defined by International Geomagnetic Reference Field (IGRF) 2005 extrapolated to August 1, 2008.

    2003-10-01

    We discuss many aspects of a reproduction of a formal painting from the XVIth century. It is a portrait of Viceroy of New Spain Luis de Velasco, El Joven or Hijo (son-see text), found at the Museum of the Pecos National Monument (near Pecos and Santa Fe, New Mexico). A formal portrait of each Viceroy of New Spain was created, and this one was painted during de Velasco's first term as Viceroy (1590 to 1595 AD). In this depiction, he is seen wearing spectacles. To our knowledge, this is the first known reference suggesting the introduction of this form of visual correction in the Spanish Colonies in the Americas and in the future United States. There are three known portraits of Luis de Velasco (son): One painting, which included his father and significant others, hangs in the Colegiata (a small cathedral) de San Luis near Valladolid, Spain. In this portrayal, he was shown as a young man without a spectacle correction. And there are two viceregal portraits (Term 1, 1590 to 1595; Term 2, 1607 to 1611) in which he wears the same spectacle correction (these are located in Mexico City).

    This article deals with a research in progress searching to take care of the faults that occur with greatest frequency in the fossil fuel power plants of Mexico with the aid of tools of computational intelligence such as the neuronal networks and the fuzzy logic, for the online recognition of the dynamic behavior patterns of variable groups. What this research looks for is the development of individual systems, in relation to the computational intelligence techniques that continuously supervise the functioning of the unit and inform the operator of the eventual faults in the understanding that on time attention to the faults will result in a minimum cost. The advantages of these diagnosis mechanisms are established in comparison to alternative diagnosis methods, such as their associative memory useful to store fault patterns. [Spanish] Se trata de una investigacion en progreso que busca atender las fallas que ocurren con mayor frecuencia en las unidades termoelectricas de Mexico con la ayuda de herramientas de inteligencia computacional como las redes neuronales y la logica difusa, para el reconocimiento en linea de patrones de comportamiento dinamico de grupos de variables. Lo que esta investigacion busca es desarrollar sendos sistemas, en relacion a las tecnicas de inteligencia computacional, que supervisen continuamente el funcionamiento de la unidad e informen al operador de fallas eventuales, en el entendido que la oportuna atencion a fallas redituara en un costo minimo. Las ventajas de estos mecanismos de diagnostico se establecen en comparacion a metodos de diagnostico alternativos, como su memoria asociativa util para almacenar patrones de falla.

    mathematics with dynamic programming to accelerate the search of a solution and (2) the development of an alternating method to solve the economic dispatch problem without restrictions. This method does not have to form the curve of incremental equivalent cost, with which a great deal of memory storage and execution time are saved. [Spanish] Se presenta un metodo para resolver el problema de asignacion de unidades termoelectricas en sistemas electricos de potencia de gran escala. El problema consiste en determinar cuales unidades generadoras deberan ser programadas para entrar o salir de operacion durante los intervalos de horizonte de planeacion, de tal forma que se satisfagan a minimo costo, y en forma confiable la demanda pronosticada de potencia electrica y las restricciones fisicas y operativas de los componentes del sistema de potencia. El metodo esta compuesto por dos etapas: la primera etapa encuentra una solucion inicial factible de unidades termo por medio de metodos heuristicos. La segunda etapa produce una solucion a partir de un estado de asignacion inicial factible. El costo de operacion se reduce aplicando programacion dinamica en aproximaciones sucesivas, de tal forma que el producto de cada interaccion constituye el estado de asignacion de menor costo encontrado hasta esa etapa. El rango de busqueda para la solucion optima es reducido aplicando tecnicas de relajacion lagrangeana para seleccionar unicamente las unidades que tienen el mayor potencial de reducir el costo de operacion. El algoritmo es validado utilizando un sistema representativo del sistema interconectado nacional que consta de 108 unidades termoelectricas agrupadas en 7 grupos de generacion, para un horizonte de planeacion de una semana dividido en intervalos horarios, conteniendo 18,144 variables discretas, 18,144 variables continuas y 39,024 restricciones. En una computadora VAX 11/780 el problema es resuelto en 55 minutos de CPU con una estimacion del 1.02% de suboptimalidad que indica que

    2010-06-01

    We describe the cannibalization of an infant bonobo (circa 2.5 years old) at Lui Kotale, in the Democratic Republic of Congo. The infant died of unknown causes and was consumed by several community members including its mother and an older sibling one day after death. Certain features concerning the pattern of consumption fit in with previously observed episodes of cannibalism in Pan, whereas others, such as the mother's participation in consuming the body, are notable. The incident suggests that filial cannibalism among apes need not be the result of nutritional or social stress and does not support the idea that filial cannibalism is a behavioral aberration.

    Yupingfeng San (YPFS) is a representative Traditional Chinese Medicine (TCM) formula with accepted therapeutic effect on Asthma. However, its action mechanism is still obscure. In this study, we used network pharmacology to explore potential mechanism of YPFS on asthma. Nucleotide-binding oligomerization domain (NOD)-like receptor pathway was shown to be the top one shared signaling pathway associated with both YPFS and asthma. In addition, NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome was treated as target protein in the process of YPFS regulating asthma. Further, experimental validation was done by using LPS-stimulated U937 cells and ovalbumin (OVA)-sensitized BALB/c mice model. In vitro experiments showed that YPFS significantly decreased the production of TNF-α and IL-6, as well as both mRNA and protein levels of IL-1β, NLRP3, Caspase-1 and ASC in LPS-stimulated U937 cells. In vivo experiment indicated that YPFS treatment not only attenuated the clinical symptoms, but also reduced inflammatory cell infiltration, mucus secretion and MUC5AC production in lung tissue of asthmatic mice. Moreover, YPFS treatment remarkably decreased the mRNA and protein levels of IL-1β, NLRP3, Caspase-1 and ASC in lung tissue of asthmatic mice. In conclusion, these results demonstrated that YPFS could inhibit NLRP3 inflammasome components to attenuate the inflammatory response in asthma.

    The thermoelectric centrals of the combined cycle type (Brayton Cycle and Rankine Cycle) present a series of opportunities to increase the efficiency of the combined cycle or of the generated power. This paper shows the methodology for the performance of energy balances in a heat recuperator (H. R.), typically employed in the combined cycle stations operating in Mexico, for the assessment of the energy harnessing in the different sections conforming a H. R. The effect of the installation of evaporative coolers and/or an absorption cooling system at the gas turbine compressor intake on the steam generation in the heat recuperator, is evaluated. This extra generation of steam is quantified for its potential use in the same absorption refrigeration system. From the assessment, it follows up that the steam generation in the H.R. is inversely proportional to the ambient temperature and that, although the increased amount of steam generated can not be harnessed in total by the steam turbine, the remaining fraction is good enough to cover the heat demand for the operation of the refrigeration system. [Espanol] Las centrales termoelectricas del tipo ciclo combinado (ciclo Brayton y ciclo Rankine) presentan un conjunto de oportunidades para incrementar la eficiencia del ciclo combinado o bien la potencia generada.

    In this article the methodology followed to diagnose the performance of the equipment where heat is transferred from the feed water, condensate and circulation water systems in fossil power plants (FPP). The data collection is made with the unit in normal operation, using local instrumentation without taking the equipment out of service for its installation. The equipment diagnosis is made through the analysis of the collected data in actual operation and the design data; for this purpose a thermal balance of the interested systems is performed to obtain all the conditions an operation data. Later on the performance indicative parameters (PIP) of actual operation and design are calculated and compared one against the other. Such a comparison reveals the performance deterioration and the possible equipment faults. The data obtained and the supplementary information are stored in a data base whose objective is that Comision Federal de Electricidad has on hand a prompt access to them in order to control the performance, compare them among similar units and power stations, and inclusively verify possible recurrent causes of low availability in the referred systems.

These poems emerge from a group initiative in which notable poets from the Madrid court took part, poets such as Lope de Vega, Pedro Calderón de la Barca, José de Pellicer, José de Valdivielso, Luis Vélez de Guevara, Juan Pérez de Montalbán and Francisco de Rojas Zorrilla. My article examines the social context in which this poetic collection is born, the composition of the book, its successful publishing history throughout two centuries as well as the reiterative representation in the poems of particular meditatio mortis topics (the staging of agony; the expression of repentance, love for Christ and hope for his mercy; and the contemplation of Christ’s body on the cross.

The implementation has the purpose of looking for alternative strategies of control to the classic ones (PID`s) that more efficiently control the variables of interest, in addition to getting into the new control techniques of control. Following the philosophy of predictive control IMC the form to applying this technique is shown, as well as the implementation of this type of controllers. A comparison of predictive control IMC is made with the scheme of conventional control (three control elements PID`s ) used at present to control the level of the deareador in the Combined Cycle Thermoelectric Power stations of Dos Bocas, Veracruz, Mexico and of Gomez Palacio, Durango, Mexico. [Espanol] El presente trabajo muestra la implementacion del esquema de control predictivo IMC (Control con Modelo Interno) con el objeto de controlar el nivel del deareador de una Central Termoelectrica de Ciclo Combinado (C.T.C.C.). La implementacion tiene la finalidad de buscar estrategias de control alternas a las clasicas (PID`s) que controlen mas eficientemente la variable de interes, ademas de incursionar en las nuevas tecnicas de control. Siguiendo la filosofia del control predictivo IMC se muestra la forma de aplicar esta tecnica, asi como la implementacion de este tipo de controladores. Se hace una comparacion del control predictivo IMC con el esquema de control convencional (control de tres elementos PID`s) utilizando actualmente para controlar el nivel del deareador en las centrales termoelectricas de ciclo combinado de Dos Bocas, Veracruz y de Gomez Palacio, Durango en Mexico.

    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 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 O conto “O Aleph”, de Jorge Luis Borges, evidencia o caráter fabulatório da letra hebraica e o de cabalista do escritor argentino. Ao exibir a proliferação de relatos possíveis, diante da complexa e artificiosa reinvenção desse signo enquanto uma metáfora da escritura, Borges faz vislumbrar, também, a criação de replicantes da escritura, clones, às vezes perversos, antagônicos ou tão similares que fazem confundir a própria noção de original.

Sin embargo, como  pasaré a demostrar, no fue esa precisamente la causa de la tremenda injusticia sino otras presentarlas por sus enemigos , quienes en sus ataques hasta llegaron a probar que no descendía de Cristianos viejos sino que tenía sangre de judíos.

    Palabras del doctor José Félix Patiño Restrepo, Académico de Número, con motivo de la Sesión Solemne de la Academia Nacional de Medicina para conmemorar el centenario del natalicio del Profesor Luis Patiño Camargo.

    Santafé de Bogotá, noviembre 21 de 1991

    Son varias las semblanzas que distinguidas personalidades de Colombia y del exterior han escrito sobre el Profesor Luis Patiño Camargo, cuya vida ejemplar dejó honda huella en la medicina y la ciencia colombianas: Carlos Lleras Restrepo y Juan Lozano y Lozano en 1978; Augusto Gast Galvis, Fernando Serpa Flórez y Alfonso Jaram illo Salazar en 1979; Eduardo Guzmán Esponda, Remando Groot y José Francisco Socarrás en 1981; Amador Neghme, de Chile en 1987; Ernesto Andradc Valderrama en 1988, y ahora Carlos Sanmartín Barberi.

    “Bella vida y bella muerte la de Luis Patiño Camargo, pensaba yo cuando iba caminando detrás del féretro, después de los sencillos oficios en la iglesia de Iza, hacia el cementerio campesino donde él dispuso que se enterrara en medio de las tumbas de sus padres y debajo de los pinos que plantó con su propia mano”. Así inició Carlos Lleras Restrepo un sentido artículo sobre Patiño Camargo publicado en la Nueva Frontera a los pocos días de su muerte, acaecida en Sogamoso el 13 de noviembre de 1978. Porque ese fue su deseo: reposar para siempre en el cementerio que domina su bello pueblo andino, Iza, donde había nacido el 24 de noviembre de 1891.

    Dijo Gast Galvis: “El Dr. Patiño, como el cacique de Inza, después de mucho peregrinar por todo el territorio colombiano, encontró un lugar de brisas tibias, cielo siempre azul, abundantes aguas, suelo fértil, en donde se pudiera vivir y morir en paz”.

    Científico, maestro, médico, naturalista, filósofo, humanista, todo eso fue Luis Patiño Camargo, y ninguno de estos términos lo caracteriza de por sí, sino más bien el conjunto de ellos

    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 In this article the relationship between the Gypsy vocabulary of George Borrow’s book The Zincali (1841 and the manuscript vocabulary of Luis de Usoz y Río is analysed. Against former interpretations, that pointed to an original character of Usoz’s work and to its use by Borrow as a source for his own vocabulary, an alternative hypothesis is formulated here: ‘Usoz’s vocabulary’ was elaborated also by Borrow, who intended to add it to his translation of Luke’s Gospel (1838. This was not possible due to the opposition of the Biblical Society of London, responsible for publishing the translation. Later, this first Caló dictionary compiled by Borrow served him as a starting point for the definitive vocabulary of The Zincali. However, this does not minimize the importance of Usoz’s manuscript, because around hundred words found in this vocabulary are missing for unknown reasons from the vocabulary of The Zincali.

Las simulaciones numericas se realizaron mediante un modelo tridimensional de circulacion costera y difusion y dispersion de calor. El analisis estadistico del banco de datos de intensidad y direccion del viento medido del 1 de enero de 1981 al 31 de diciembre de 1983, indica que el numero de valores de mayor ocurrencia se presento dentro del intervalo de 180 grados a 315 grados. Por lo mismo, el efecto del viento proveniente del sector sur genera un patron de circulacion superficial de flujo norte que alejan de la obra de toma el agua caliente descargada. En contraste, el viento que proviene del sector norte genera corrientes superficiales de flujo sur que impulsa el efluente hidrotermico hacia la obra de toma. Las comparaciones entre los resultados de las simulaciones numericas y los datos de campo indican que, para una variedad de condiciones ambientales meteorologicas y oceanograficas representativas del Sitio Tuxpan (ST), el modelo simula correctamente los patrones de difusion y dispersion superficial de los efluentes medidos los dias 19, 20 y 21 de agosto de 1992 (Caso I) y 26 de noviembre de 1992 (Caso II). La precision promedio con la cual el modelo predice las areas de impacto de los efluentes descargados en el ST es de {+-} 11%.

    Full Text Available Monte Grande is a small (41.8 km mountain range located at the southernmost part of the northern plateau of Mexico. It has a dry climate and its vegetation is characterized by pinyon woodland, oak scrub and three kinds of xerophytic scrub. Based on its flora of 397 species, we analyzed the historie phytogeography of Monte Grande, using only the taxa (families, genera and species that have a restricted distribution. At the family level, we identified three patterns of distribution: 1 from North America to northern South America; 2 mostly in the American continent; 3 families related to the Mediterranean region. At the genus level, five patterns were identified: 1 endemic of arid and semiarid lands of Mexico and adjacent regions of the United States; 2 from southern United States to Central America; 3 broadly distributed, but highly related to the Antillean region; 4 with Mediterranean relations; 5 disjunct or vicariant between the arid lands of North and South America. At the species level, nine patterns of distribution were identified: 1 septentrional plateau; 2 meridional plateau; 3 all plateaus and adjacent regions; 4 all plateaus-Sierra Madre de Oaxaca; 5 all plateaus-northwestern coast plain; 6 all plateaus-both coastal plains; 7 all plateaus-northeastern coastal plain; 8 Mexican xerophytic region; 9 all plateaus-both sierras Madre. These patterns are unlikely to be accidental, as they agree with recent theories about the process that led to the present landform configuration of the American Continent. On the basis of this interpretation, we postulate a major role of the Caribbean and the Former Mediterranean in the florigenesis of present linages of the arid and semiarid lands of Mexico.La sierra Monte Grande, con una extensión de 41.8 km, se localiza en el sur de la altiplanicie septentrional de México.

Al nivel de familia se identificaron tres patrones de distribución: 1 desde Norteamérica hasta el norte de Suramérica; 2 con mayor amplitud en el continente americano; 3 familias relacionadas con la región del Mediterráneo. Al nivel de género se encontraron cinco patrones: 1 endémicos de las zonas semisecas a muy secas de México y regiones adyacentes de Estados Unidos; 2 desde el sur de Estados Unidos hasta Centroamérica; 3 de distribución amplia pero con marcada relación antillana; 4 relacionados con la región del Mediterráneo; 5 disyuntos o vicariantes de las zonas áridas de Norte y Suramérica. Al nivel de especie se identificaron nueve patrones de distribución: 1 altiplanicie septentrional; 2 altiplanicie meridional; 3 altiplanicie y zonas adyacentes; 4 altiplanicie-Sierra Madre de Oaxaca; 5 altiplanicie-planicie costera noroccidental; 6 altiplanicie-planicies costeras noroccidental y nororiental; 7 altiplanicie-planicie costera nororiental; 8 región xerofítica mexicana; 9 altiplanicie sierras Madre. Se descarta que estos patrones sean casuales, pues concuerdan con teorías recientes sobre el proceso que culminó con la configuración actual del continente; se postula un papel destacado del Caribe en la florigénesis de linajes vegetales actuales de las zonas semisecas, secas y muy secas de México y en el mismo sentido un papel destacado del Mediterráneo Antiguo.

    We have analysed the meals for lunch and dinner at the University cafeteria, during one Winter week (June through September); in this season the menus are repeated every week round. A percentage analysis (humidity, ashes, lipids, protein, raw fiber, and nitrogen-free extract) was carried out on the sample, which were appropriately processed, thus allowing us to know the nutrients amount and caloric value of each meal. When examining both the formulas ingredients and the technique applied to the preparation of the meals, it was found that they have the best cooking quality, and also that their amount is sufficient (see tables). As to the meals nutrients, the results allow us to conclude that the diets are hypercaloric as well as hypoproteic, with a preponderance of proteins of animal origin.

    This paper describes the functionality of the Integral System of Information for the Diagnosis of Predictive Maintenance (SIIDMP) in the thermoelectric centrals, whose primary target is to give support to the personnel related with the maintenance and operation of the thermoelectric central to optimize the application of the inspection, maintenance and its associated costs. It is important to comment that in the generating power stations of Comision Federal de Electricidad (CFE) techniques and methodologies for the preventive and corrective maintenance are applied, in addition of which they count on electronic equipment of operation dedicated to the inspection and control of vibratory equipment. The architecture of the SIIDMP is of the client-server type and for its design and implantation Windows NT 4.0 was used as operating system, SQL Server 7.0 as server and manager of the database, Visual C++ for the programs of data mining, Vision Basic 6.0 for the codification of the application programs and Interface Man-Machine (IMM), the communication mechanism Open Data Base Connectivity (ODBC) to establish the connection with the different data sources, as well as libraries of symbols and graphs that were included in the interface of the user. The main objective of the SIIDMP is to take care of the own necessities on optimization, improvements and savings in the operation of the power stations. With systems like the SIIDMP, a reduction of the costs due to shutdowns by accidental failures of the main equipment is looked for, limiting the deterioration of the equipment, as well as to provide knowledge and aid to all the personnel who take part in the management of the operation and conservation of the facilities of the power station.

    planta termoelectrica de 350 MW, que utilizaria carbon como combustible, en el simulador de procesos ASPEN HYSYS. Para este proceso se requieren dos columnas: una de absorcion, en la cual entran los gases y el solvente, que en este caso fue una solucion de monoetanolamina (MEA) al 30%. La MEA reacciona con el CO{sub 2} contenido en los gases, reteniendolo, de manera que los gases restantes que son emitidos al ambiente, ya no lo contienen. La MEA y el CO{sub 2} capturado pasan a la segunda columna donde estos dos componentes se separan, utilizando energia termica para regenerar la MEA liberando el CO{sub 2}. El CO{sub 2} liberado sale por la parte superior de la columna y la MEA recuperada, que es reutilizada en la columna de absorcion, por el fondo. La concentracion de CO{sub 2} en los gases de la combustion es de 14.54% volumen. La simulacion se realizo definiendo una eficiencia de captura de 90%, lo que arrojo un consumo de energia termica para regenerar la MEA de 4.75 GJt/ton CO{sub 2}, que seria suministrada por la central termoelectrica. Considerando una capacidad de gases a tratar de 280 ton/h (por tren) se determino la altura de las columnas de absorcion y desercion, asi como el flujo de solucion de MEA.

  2. Boiler model of a 300 Mw fossil fuel power plant for the turbine turning simulator; Modelo de caldera de una planta termoelectrica de 300 Mw para el simulador de rodado de turbina

    Rossano Roman, Miguel [Instituto de Investigaciones Electricas, Cuernavaca (Mexico)

    1993-07-01

    The objective of the model is to reproduce the behavior of a boiler of a 300 Mw fossil fuel unit, in the training turbine turning simulator. This simulator was designed to be used in the training that is performed in the control rooms or training centers of the fossil fuel power plants of the Comision Federal de Electricidad (CFE). In this article the equations of the model for a 300 Mw thermal plant are described, based in balances and physical relationships. The basic considerations and simplifications are shown. The model considers the combustion in the furnace, the dome, the downcomers, the recirculation pumps, the water walls, the superheater and the reheater. The mass and energy balances take into account the sensible heat of all the constituents involved, as well as the combustion heat. Heat transference zones by convection or by a combined mechanism convective-radiant, in the boiler furnace, are considered. The dome pressure is modeled with basis in the mass and energy balance, considering all the existing sources and sinks. The simulation also reflects the pressure transients due to thermal variations, combustion variations, and steam demand variations. The heat transference by convection is considered for all the tube banks along the combustion gases path to the stack. Comparisons were made with the design and operation data of the power station, using a selection of transient states to demonstrate de model fidelity. This selection was focussed of transients states, at the unit start up, since in this operation stage the turning and the heating of the turbine is accomplished.

    The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

    of the computation, the programming languages and the numerical methods allow to develop mathematical models that simulate in an approximate manner the processes to control, as it is the case of the combined cycle thermoelectric power station and in this way making the evaluation of algorithms of modern control possible. In chapter I a functional description of the steam turbine process is given. Since this belongs to a combined cycle thermoelectric power station, it is begun with the description of this power station, later to emphasize the subsystem of the steam turbine and emphasize each one of the elements that comprise this last one. [Espanol] Este trabajo de investigacion esta orientado a disenar, desarrollar y validar un algoritmo de control moderno, que permita la obtencion de mejores desempenos en el control de velocidad de una turbina de vapor perteneciente a una central termoelectrica de ciclo combinado, en todo el intervalo de operacion, asi como la obtencion de mejores desempenos en el control de la cantidad de megawatts generados por la misma cuando esta acoplada a un generador electrico, comparando el desempeno con el obtenido mediante el controlador convencional existente. Los cambios en la referencia de velocidad o carga, son a solicitud del operador y se dan siempre en forma de rampa, indicando la rapidez con la que se desea efectuar el cambio de valor en la referencia. Esta es la razon por la cual el objetivo principal del control a disenar es realizar un buen seguimiento a referencias del tipo rampa. En el subsistema de la turbina de vapor existente el inconveniente de que las valvulas que regulan el flujo de vapor hacia la turbina, presentan un acoplamiento con la valvula del bypass que permite derivar el flujo de vapor hacia el condensador principal sin tener que pasar por la turbina. Es por esto que se propone un control multivariable que contemple la interaccion que se presenta entre las valvulas antes mencionadas, partiendo de un diseno

    Full Text Available A LA COSTA DE LUIS A. MARTINEZ : LA DEFENSE D’UN PROJET LIBERAL POUR L’ÉQUATEUR ? A la Costa est souvent analysé comme une peinture de moeurs, témoignage de la réalité sociale et politique de l´Équateur de la fin du XIX et du début du XX. En effet, ce roman prétend décrire le conflit traditionnel qui oppose socialement, économiquement et politiquement les Andes et la Côte. Mais il se présente aussi et surtout comme la défense d´un projet libéral pour l´Équateur et développe une démonstration idéologique systématique. En outre, il propose une lecture du sens de la vie et une réflexion sur le devenir de l´homme dont la portée dépasse largement l´argumentation idéologique. Ce sont sans aucun doute ces nuances, introduites tout au long de la narration, qui permettent à l´oeuvre d´échapper à son statut exemplaire, simple témoignage d´une époque, pour proposer une vision personnelle et créative. Muchos han visto en A la Costa una novela de tendencia costumbrista, testimonio de la realidad social y política del Ecuador a finales del siglo XIX y comienzos del XX. En efecto, la novela pretende describir el conflicto tradicional social, económico, político entre Sierra y Costa. Pero es también, y ante todo, la defensa de un proyecto liberal para Ecuador, desarrollando una sistemática demostración ideológica. Además, propone una lectura del sentido de la vida y una reflexión sobre el porvenir del hombre cuyo alcance va más allá de la defensa de un proyecto ideológico. Sin duda son estos matices, introducidos a lo largo de la narración, los que permiten que la obra escape del estatuto de novela ejemplar y testimonial para proponer una visión autónoma y creativa.

    Full Text Available Resumen: Siguiendo el modelo de El nombre de la rosa de Umberto Eco, las novelas El manuscrito de piedra y El manuscrito de nieve de Luis García Jambrina reconstruyen Salamanca en la época de los Reyes Católicos con una ficción detectivesca que narra las actividades de un joven Fernando de Rojas, el supuesto autor de La Celestina, con el fin de aclarar una serie de crímenes y muertes, entre ellas la del príncipe Juan de Trastámara. Mientras que en El manuscrito de piedra los asesinatos son obra de heterodoxos españoles que viven escondidos en la cueva de Salamanca, en El manuscrito de nieve los asesinatos son parte de la larga rivalidad entre los clanes de Salamanca de San Tomé y San Benito. Aparte de la rareza de hacer protagonistas e interlocutores a Fernando de Rojas, Celestina y Lázaro de Tormes, García Jambrina también da respuestas a enigmas literarios como la génesis de La Celestina y el "caso" del Lazarillo, cuyas intertextualidades encontramos por doquier en estas novelas.Abstract: Modeled after Umberto Eco´s The Name of the Rose, Luis García Jambrina novels’ El manuscrito de piedra and El manuscrito de nieve reconstruct Salamanca at the times of the Catholic Monarchs with a detective fiction that narrates the activities of a young Fernando de Rojas, the presumed author of La Celestina, in order to clarify a number of crimes and deaths, including that of Prince John of Trastamara. While in El manuscrito de piedra the murders are the work of heterodox Spaniards who live hidden in a subterraneous cave of Salamanca, in El manuscrito de nieve the murders are part of the longstanding rivalry between the Salamanca clans of Saint Tomé and Saint Benito. Apart from the oddity of making Fernando de Rojas, Celestina, and Lázaro de Tormes protagonists and interlocutors, García Jambrina also gives unusual responses to literary enigmas as the genesis of La Celestina and Lazarillo´s ‘case’, whose intertextualities we find here

    logic theory and its performance was evaluated using a non- linear mathematical model that emulates the CTCC behavior. The fuzzy supervision system is integrated by three main modules: Supervision of blades temperature during the starting stage of the UTG; Supervision of blades temperature runback during the power generation stage of the UTG, and Control by Temperature during power generation stage of the UTG. The temperature fuzzy supervisor is implemented in a nonlinear mathematical model that simulates a CTCC. The obtained and analyzed results in the different sceneries of the simulation tests show that the temperature fuzzy supervision system displays a better performance than the obtained with the scheme of conventional supervision. [Spanish] En las Unidades Turbogas (UTG) de una Central Termoelectrica de Ciclo Combinado (CTCC), una de las variables criticas tanto desde el punto de vista operativo como desde el punto de vista de seguridad, es la temperatura de los alabes de la turbina. El mejor desempeno de la unidad turbogas desde el punto de vista de generacion electrica se obtiene cuando es posible lograr la mayor eficiencia termica. Desde el punto de vista de seguridad se busca mantener la temperatura de los alabes en el limite impuesto por el fabricante, garantizando con esto la integridad de las partes internas de la UTG al evitar que esfuerzos termicos considerables decrementen su vida util. Para mantener la temperatura de alabes dentro del limite establecido, el sistema de control de la UTG cuenta con un sistema de supervision de temperatura de alabes, que modifica la referencia de los controladores PI de velocidad o de potencia generada, mismos que regulan la valvula de flujo de combustible a la camara de combustion de la UTG. Este sistema de supervision esta basado en condiciones logicas para generar su salida.

    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 Manteca’s 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, Manteca’s likely disconnection from the theatrical world.

Essa opinião é corroborada pela análise de uma intervenção específica: o caso de Luis, processado por vários homicídios na década de 1980 na Argentina. Esse percurso é oferecido como uma possível explicação de como, no funcionamento do Sistema de Justiça Penal, a mediação moral distingue emoções como forma de apoiar certas decisões e práticas. Ao mesmo tempo, são descritas as transformações históricas em uma série de instituições para seu tratamento ao longo de 28 anos de confinamento. The article The case of Luis: Moralities, Emotions and the Penal Device of ‘Forgiveness’ proposes to reflect on “forgiveness” as a value that organizes the relations that develop around the penal treatment of the figure of unaccountability. This opinion is supported by the analysis of a specific intervention: the case of Luis, charged with several murders in the 1980s in Argentina. This case is offered as a possible explanation of how, in the workings of the Criminal Justice System, moral mediation distinguishes emotions as a way of supporting certain decisions and actions. At the same time, a description is presented of the historical transformations that have occurred at institutions where he has been treated over the course of 28 years of confinement.Keywords: emotions, moral value, forgiveness, security injunction, penal device

  14. A stochastic estimate of ground motion at Oceano, California, for the M 6.5 22 December 2003 San Simeon earthquake, derived from aftershock recordings

    Science.gov (United States)

    Di, Alessandro C.; Boatwright, J.

    2006-01-01

    The U.S. Geological Survey deployed a digital seismic station in Oceano, California, in February 2004, to investigate the cause of damage and liquefaction from the 22 December 2003 M 6.5 San Simeon earthquake. This station recorded 11 M > 2.8 aftershocks in almost 8 weeks. We analyze these recordings, together with recordings of the mainshock and the same aftershocks obtained from nearby stations in Park Hill and San Luis Obispo, to estimate the mainshock ground motion in Oceano. We estimate the Fourier amplitude spectrum using generalized spectral ratio analysis. We test a set of aftershocks as Green's functions by comparing simulated and recorded acceleration amplitude spectra for the mainshock at San Luis Obispo and Park Hill. We convolve the aftershock accelerograms with a stochastic operator to simulate the duration and phase of the mainshock accelerograms. This approximation allows us to extend the range of aftershocks that can be used as Green's functions to events nearly three magnitude units smaller than the mainshock. Our realizations for the mainshock accelerogram at Oceano yield peak ground accelerations distributed as 28% ?? 4%g. We interpret these realizations as upper bounds for the actual ground motion, because our analysis assumes a linear response, whereas the presence of liquefaction indicates that the ground behaved nonlinearly in Oceano.

En este articulo se presenta un esquema de diagnostico de fallas, aplicado al generador de vapor de una unidad termoelectrica, basado en tecnicas de modelado de sistemas dinamicos mediante redes de Petri. Frente a otros metodos, el esquema ofrece mayor facilidad para su implementacion, rapidez de adaptacion ante cambios de zona de operacion y buena robustez. Una manera de reducir el efecto de las fallas en un sistema de produccion, consiste de dos pasos. El primero es diagnosticar la falla tan pronto como ocurra y subsecuentemente poner en practica acciones correctivas. El concepto de diagnostico de fallas se relaciona con la primera etapa y comprende tanto la deteccion, como la localizacion de esta. Es decir, ademas de determinar que una falla esta presente, se sabe en que componente ha ocurrido. Con base en lo anterior, es claro que un sistema de diagnostico requiere supervisar las variables que caracterizan el comportamiento de las fallas, a fin de detectarlas en el momento en que se presenten e informarlo al operador. Con esta informacion, el operador podra realizar las acciones correctivas necesarias para que la planta siga operando en la medida de lo posible.

    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 roads that separate writers often end with a paradox, happy proximity. 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.

Among the Nobel Prize winners, scientists, doctors, and thinkers invited to this year's conference is Luis Álvarez-Gaumé, a theoretical physicist at CERN. Having made significant contributions to the understanding of gravitation, minimal supergravity theory and supersymmetry, Álvarez-Gaumé was an obvious choice to be invited to share his thoughts about the theory and reality of current physics ideas with the conference attendees.

El tema gira alrededor de la invasión de Panamá, por parte del ejército estadounidense, con la intención de deponer a Manuel Noriega en 1989. El estudio se centra en el tema de la violencia y en la forma como se incorpora en la ficción dándole un carácter peculiar, por el tratamiento histórico del tema que logra alejarse de la narración historicista.

    2011-06-01

    Full Text Available The present article analyzes some of the religious implications deriving from the famous controversy about the legality or illegality of theatre in the 17th century and in the city of Valencia. The question arose from an episode in which Don Luis Crespi de Borja was directly implicated. Crespi was the founder of the Oratory of Saint Philip Neri in the Valencian region and a persistent fighter against comedy. As a consequence of his position in this affair members of the Oratory were pursued by other ecclesiastical sectors favouring theatre.

    Full Text Available A pesar de que en la documentación gallega existen referencias, aunque claramente insuficientes, a la presencia judía desde el siglo xi, no es hasta el siglo XV cuando las noticias conservadas son lo suficientemente abundantes como para elaborar la biografía de algunos de los personajes más destacados. Tal es el caso de Judá Pérez. Con este nombre se documentan dos personajes homónimos diferenciados por el ámbito cronológico en el que se desarrolla su actividad profesional. El primero desde el año 1423 a 1456, y el segundo desde el año 1476 a 1488, siendo este último Judá el objeto de este artículo. La particularidad de este personaje no viene determinada por su actividad profesional —mayordomo de varias casas condales y señoriales y arrendadorrecaudador de rentas reales—, sino por la constatación documental de su conversión al cristianismo, con el nombre de Luis Alonso, y la continuidad de su actividad profesional como arrendador de rentas reales.Although there are some references in the Galician papers, even though clearly insufficient, about the Jewish presence since the Xlth century, it is not until the XVth century when the news presen/ed are abundant enough to write the biographies of some of the most distinguished figures of the time. Such is the case of Judá Pérez. Two homonymous men are documented with this ñame, and they are distinguished by the period of time when they carried on their professional activities. The first one, since the year 1423 to 1456, and the second one since 1476 to 1488; being this last one, Judá, the object of this article. The peculiarity of this person doesn t come from his professional activity, —administrator of several earls and lords, and lessor/ tax collector of royal revenues—, but from the documental confirmation of his conversión to Christianity, under the ñame oí Luis Alfonso, and the continuation of his professional activity as a lessor of royal revenues.

    2009-06-01

    Full Text Available En este artículo se ensaya una aproximación a la labor estético-filosófica del argentino Luis Juan Guerrero (1899-1957, a través de un cotejo de su temprana y productiva recepción de algunos aspectos centrales de la obra de Walter Benjamin. Se intenta mostrar que esta clave de lectura permite un acceso privilegiado a la labor de Guerrero, a la vez que ayuda a construir una imagen más compleja y matizada de la generación intelectual "antipositivista" a la que perteneció. La olvidada obra de Guerrero se compone principalmente de trabajos sobre ética, psicología y estética. Acotaremos nuestra atención a su principal trabajo, y acaso la obra sobre estética más ambiciosa jamás escrita en nuestro país: Estética Operatoria en sus Tres Direcciones. Se muestra en el artículo que la summa estética de Guerrero, si bien expresa con toda claridad las preocupaciones centrales de una generación intelectual marcada por la cultura alemana de entreguerras y por la problemática de la "crisis de la cultura", inscribe, a su vez, una anomalía -benjaminiana-, una inflexión político-materialista, que pone en cuestión la idea frecuente de que la "crisis de la cultura" una y otra vez diagnosticada en aquella época mostró siempre alternativas "espiritualistas" de resolución.This essay deals with the aesthetic-philosophical work of the Argentinean Luis Juan Guerrero (1899-1957, through a consideration of its early and fruitful reception of some central aspects of Walter Benjamin's work. It is shown that this perspective allows a privileged access to Guerrero's work, at the same time that it makes more complex the image of the "anti-positivistic" intellectual generation in Argentina. Guerrero's forgotten work includes principally contributions on ethics, psychology and aesthetics. This essay will pay attention only to his most important work, maybe the most ambitious aesthetic work ever written in Argentina: Operatory Aesthetics in its Three

    Luis Moya excelled in this area, re-exploring this construction technique. Moya benefited in this regard from his thorough knowledge of the early twentieth century works of the Guastavinos in New York acquired during his visits to the U.S.A. with Professor Collins.
    His architecture featured tiled vaults with medium-sized spans, normally reinforced with exposed internal Basque tiled arches or ribbing on the extrados.
    He described his architectural experimentation in this field in a book titled "Bóvedas tabicadas" (tile vaults, one of the few extensive treatises on the subject, which surpassed the papers published earlier by Fornés-Gurrea and Bergós.

    Después de la Guerra Civil, y ante la precaria situación económica del pais, se volvió a retomar en España, la construcción tabicada como medio de encomizar acero en la edificación, y aprovechando la mano de obra barata del momento.
    Luis Moya destacó en este aspecto, reinvestigando sobre la construcción tabicada siendo perfectamente conocedor de la obra de los Guastavino en Nueva York, de principios de siglo, por sus visitas realizadas acompañadas del Profesor Collins a EEUU.
    La arquitectura de Moya destacó por aplicar soluciones de bóvedas tabicadas de mediana luz que normalmente reforzaba empleando arcos tabicados internos vistos, o bien acostillando las bóvedas por sus trasdós.
    Esta labor arquitectónica basada en su propia experimentación constructiva, la publicó en el libro "Bóvedas Tabicadas", siendo uno de los pocos tratados amplios sobre este tema existente, superando con él a lo publicado por Fornés-Gurrea y Bergós con anterioridad.

    Full Text Available Ideile lui Rousseau au avut un impact major asupra societăţii la sfârşitul sec. al XVIII-lea şi pe parcursul întregii perioade a sec. al XIX-lea. Aceste idei au imprimat un suflu modern cugetului său, fiind considerat şi un ideologist politic, o voce puternică a Revoluţiei Franceze şi un pioner al curentului romantic. În legătură cu domeniul nostru de studiu, paradoxurile concepţiei politice ale lui Rousseau se referă la contradicţia dintre aspiraţiile modernităţii şi criticile violente ale progresului social. El pune accentul pe contradicţia dintre încrede-rea deplină în ,,contractul social”, ca pattern cultural şi lipsa de încredere în ,,educaţia socială”. Unicul mod de a depăşi aceste contradicţii este abordarea noului model al filosofiei educaţiei bazat pe reforme radicale pentru a facilita autodezvoltarea individului.   THE PARADOXES OF POLITICAL CONCEPTION IN THE WORK OF JEAN-JACQUES ROUSSEAUHis ideas have a big impact on the society at the end of the 18th century and the whole 19th century period. These ideas transform his spirit into a modern one, as well as a political ideologist, main voice of the French Revolution and pioneer of the Romantic Movement. Related to our article subject, Rousseau's political conceptual paradoxes refer to the contradiction between moderni-ty aspiration and the violent critic of the social progress. He emphasizes the contradiction between full trust of the "social contract", as a cultural pattern and the distrust of the "social education." The only way to leave the contradictions behind is his new education philosophy pattern based on a radical reform in order for the individual to develop himself.

    2002-01-01

    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.

Don Diego Luis Moctezuma played an important role during the second half of the 16th century and the first years of the XVIIth, first as son of don Pedro Moctezuma, who sends it to the Court and Kingdom of Castile to defending before the King of Spain and the Council of The Indies his interests as legitimate inheritor of Moctezuma Xocoyotzin. Later, when don Diego Luis converted into successor of his brother don Martin Cortés Moctezuma, one sees affected by the politics of the Crown and the Council of The Indies of systematic weakening of the indigenous nobility. His departure of the New Spain and the promises broken by part of the Crown determine the politics of Philip II and Philip III with the inheritors of Moctezuma Xocoyotzin.

    Full Text Available Luis Muñoz (1966 is one of contemporary Spain’s most salient poets. His work has been described as demonstrating a discourse of ellipsis; yet no study has examined in detail his masterful use of syntactic and figurative omission. In fact, even though Muñoz’s published collections to date span two centuries, no single study has been devoted to his decidedly innovative expressivity. His work has been commented on in various panoramic essays considering contemporary poetry published in Spain at this temporal intersection and a number of his poems have been gathered into noteworthy anthologies of this same era. His poetry has been nominated for prestigious awards in Spain and in 2001 Correspondencias ‘Correspondences’ received the fourth Premio Internacional de Poesía del 27 as well as the Premio de Ojo Crítico de Poesía . The present study examines Muñoz’s most recent Querido silencio (2006 ‘Dear Silence’ where ellipsis figures prominently as the poet maximizes and exploits conceptual and linguistic efficiency. In one exemplary poem, “Dejar la poesía” ‘Leave Poetry,’ two syntactically silent subjects engage in an innovative conversation concerning the nature of poetry. At the same time this intriguing dialogue also offers a unique response to the essential question framing this poem and the collection as a whole: Why is poetry an addiction?

    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.

    Full Text Available This article will analyze the urban plans of those municipalities in the Province of Valencia that embraced the technical assistance given by the Provincial Council for the planning composition, at the time of Luis Albert Ballesteros, the provincial council architect. 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. The urban plans of the Provincial Council represent the latest inheritance of the extension models and interior remodeling. In the transition to the Land Planning Act (Ley de Suelo of 1956, these plans have the interest in being, in addition to the last examples of the so-called urbanism in the municipal tradition, one of the ancestors of the current master plans of urban development (plan general de ordenación urbana.

    Full Text Available En 1996 aparece publicada la obra Donde ladrón no llega, del escritor paraguayo Luis Hernáez; este trabajo plantea una nueva lectura de la experiencia de las Reducciones Jesuitas en el Paraguay. Es, precisamente, esa forma de valoración en la recreación de la historia la que motiva este texto, ya que presenta una reconstrucción y una mirada crítica sobre un proyecto utópico adelantado en América. Tal propuesta es evaluada desde las voces de aquellos que –aún siendo protagonistas directos del evento social- no tuvieron una voz que se destacara en la delimitación de esta experiencia. Así, se abordará qué tipo de visión de la historia plantea el autor y cómo esta perspectiva se desarrolla en torno a una concepción específica de la propuesta de la utopía para América Latina.

    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.

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

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

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

    2006-12-01

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

    2001-01-01

    Full Text Available It is always contoversial to proclaim a literary work, at face value, as a sociocultural study of a particular society. It is even more controversial when one deals with a hybrid work, combining factors from two completely distinct societies. Yet, there are some literary works that seem to call for exactly this type of analysis, presenting a range of ideas which in retrospect reveal origins of significant sociocultural trends. Such is the case of Luis Spota's Murieron a mitad del río (1948. This novel presents a panorama of ancestral problems in the life of thousands of immigrants and inhabitants of the Mexican-U.S. border region trying to achieve a "better life for them and their children," yet forced to live in social limbo. These individuals reside neither entirely in Mexico nor in the United States, but in a place where the existence of tensions started with the competition for jobs amongst the "already in" and the "newly arrived" (regardless of the legal status augmenting the differences created by a new environment. Although only implicitly present in the novel, some of these problems are approached from a legal point of view creating, contrary to their intended purpose, a better means for the selection of immigrant manual labor. Although not in the novel, a case in point would be the new "walls of ignominy" along the Tijuana-San Diego crossing, where undocumented migration has shifted east toward Calexico and other parts of the Arizona desert. Since conditions to cross the border there illegally are more rigorous, only the young and strong dare to do it. This essay examines the manner Spota uses to expose his particularly "urban" point of view and a set of social problems, from a cultural theory point of analysis. It demonstates that Murieron a mitad del río presents a microcosm of the issue and in a way, predicts some of the main dilemmas that both countries will encounter through the years. Thus, Spota becomes a visionary, dealing in

    Benecke, Mark; Rodriguez y Rowinski, Miguel

    2002-01-01

    This is the first scientific report on the crimes of the homosexual paedophile sadist Luis Alfredo Garavito Cubillos, based on a research stay of the authors in Columbia, and including discussions with the investigators, and the offender. Between 1992 and 1999, Garavito killed more than 200 children in the core age span between 8 and 13 years (as an exception, 6 to 16 years). His modus operandi remained stable. During daytime, he lured children of a lower social status out of crowded parts of the city into hidden areas that were overgrown with high plants. Garavito promised either payment for easy work, or drugs, or made other socially believable offers. The children were tied up, tortured, raped, and killed by at least one cut in the lateral part of the neck, or by decapitation. During the killings, Garavito was drunk. Even after his arrest (for attempted sexual abuse under a wrong identity) it was not immediately possible to track his crimes since Garavito had frequently changed his places of stay and his jobs. He also grew different hairdos and used wrong names. During his still ongoing confessions, he directs the investigators correctly to all scenes of crime spread over large parts of Columbia. In our report, we give an overview over the course of investigations, hint to similarities in the cases of the German serial killer Denke (1920's) and homosexual paedophile serial killer Jürgen Bartsch (1960's), and give preliminary impressions on the offender's personality. Furthermore, the violent environment and juridical peculiarities in Columbia are discussed. In spite of a total penalty of 2600 years in prison, it is formally well possible that Garavito will be released out of prison within the next 10 to 20 years, i.e. even before the maximum sentence of 40 years will be over.

Instead, Cochetopa Park subsided passively as the >500 km3 Nelson Mountain Tuff vented at 26.9 Ma from an "underfit" caldera (youngest of the San Luis complex) 30 km to the SW. Three separate regional ignimbrites were erupted sequentially from San Luis calderas within an interval of less than 50-100 k.y., a more rapid recurrence rate for large explosive eruptions than previously documented elsewhere. In eruptive processes, volcanic compositions, areal extent, duration of activity, and magmatic production rates and volumes, the Southern Rocky Mountains Volcanic Field represents present-day erosional remnants of a composite volcanic field, comparable to younger ignimbrite terranes of the Central Andes. ?? 2008 Geological Society of America.

    El estudio histórico siempre ha resultado un elemento interesante para el poder político, pues es a través de la Historia cómo se construyen las identidades colectivas. Describir a Mariano Luis de Urquijo como filósofo volteriano entra dentro de estas relaciones entre la Historia y la política. Este trabajo pretende desenmascarar la realidad histórica denunciando las manipulaciones que la historiografía reaccionaria ha realizado sobre la figura de Urquijo.

    2016-04-01

    Full Text Available As opposed to other Peruvian films, where the Andes appear showcased as a transit territory which must be fled, in Los Perros Hambrientos (1976, Cuzquean filmmaker Luis Figueroa shares a view of the mountains and fields as a political place of possibility and resistance against the landowner’s arrogance. While it dramatically differs from the original novel by Ciro Alegría, it also finds in the text the necessary basis to show the moral decadence of the landowner, to abandon the bucolic nostalgia and the animal parable of the text, and submerge itself in the savage dichotomies of rich man / poor man and peasant versus landowner.

En el año 2006, el organismo encargado de su custodia, el Instituto de Patrimonio Cultural del Ministerio de Cultura, ejecutó tres etapas de exploración arqueológica, que abarcaron las áreas Traspatio, Patio Central y las Naves Este y Oeste de la edificación. Este trabajo reseña el análisis de la documentación arqueológica obtenida en el sitio, a partir de la realización de dicho proyecto, denominado EACUSAC (Estudio Arqueológico del Cuartel San Carlos, que representa además, la tercera campaña realizada en el sitio. La importancia de este yacimiento histórico, radica en su participación en los acontecimientos que propiciaron conflictos de poder durante el surgimiento de la República y en los sucesos políticos del siglo XX. De igual manera, se encontró en el sitio una amplia muestra de materiales arqueológicos que reseñan un estilo de vida cotidiana militar, así como las dinámicas sociales internas ocurridas en el San Carlos, como lugar estratégico para la defensa de los diferentes regímenes que atravesó el país, desde la época del imperialismo español hasta nuestros días.

    Full Text Available Este artículo analiza cómo, en El Cortesano, la música y la actuación musical se ven fuertemente afectadas por el carácter burlesco e ingenioso de todos los personajes que frecuentan las reuniones de Fernando de Aragón y de la reina Germana de Foix. Por lo tanto, el músico Milán, para cumplir con todas las expectativas de este mundo del entretenimiento y del juego, debe basarse necesariamente en una serie de opciones interpretativas que permitan actuaciones rápidas en función de las demandas de su público. Lo que emerge es una imagen del músico y de la música diferente de lo que se esperaría normalmente. En una sociedad de este tipo, no cuenta la música entendida en su estética y aspectos técnicos, sino la capacidad de gestionar las apariencias y someterse a las pruebas y los mandatos impuestos por los rituales del juego cortesano. Tenemos muchos ejemplos en que Milán se muestra con pasividad y sumisión. Pero es normal, porque esto entra en los códigos de la vida de la corte. This article takes into consideration El Cortesano (1561 by Luis Milán: in this text the musical performance is strongly influenced by the playful attitudes of the individuals who attended the court meetings of Fernando de Aragón and Germana de Foix. Therefore, the musician has to keep in mind every expectation of courtly entertainment and gaming, and morevoer he must open his interpretative options to meet also the demands of the public. What emerges is a picture of the musician and his music that is different from what one would expect in another social context. In such aristocratic society as the Duke of Calabria, music was not understood only in terms of its aesthetic values and technical aspects, but it also required that the player accepted the rituals of the courtly game.

  6. Low-altitude aerial color digital photographic survey of the San Andreas Fault

    Science.gov (United States)

    Lynch, David K.; Hudnut, Kenneth W.; Dearborn, David S.P.

    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

  7. Puerto Rico and migration: a view through short stories by José Luis González

    2017-03-01

    Full Text Available In this article, an analysis is made of a selection of short stories by Puerto Rican writer José Luis González (1926-1997, all of them dealing with the theme of Puerto Rican migration at the middle of the 20th century. As an introduction, there is an overview of the historical, social and political background that led to migration in Puerto Rico. Later on, causes and consequences of internal migration, that is to say, from the countryside to the cities, are presented. In the case of external migration, working conditions, economic stability, quality of life and identity of Puerto Ricans in the United States are also discussed. Finally, the discrimination suffered by immigrants in big cities through "cultural racism" —a concept that explains the creation of an imaginary around the Puerto Rican community, which facilitates the formation of a cheap labor force  hiding the true causes of their marginalization in education and employment fields— is addressed. In the conclusion, it is highlighted the importance of studying the works of José Luis González towards an understanding of the aspects that make up the phenomenon of migration and its effects and impact, not only in the Caribbean, but in the world at large.

    1967-08-01

    The usual surveys of completed suicides, encompassing, as they do, large geographical areas, are of limited value to physicians of a particular community. The unique and differentiating characteristics of the suicides in his locale may be "washed out" in these large surveys.San Mateo County has an annual suicide rate of 17 per 100,000 and a disproportionately high incidence in persons over 65 years old. In this particular county females, widows and Orientals are more prone to suicide than has usually been reported elsewhere. Alcohol was directly or indirectly involved in a significant number of instances. Many of the persons who killed themselves were under a physician's care at the time of self-destruction. There are probably important ecological and sociological variables as well as personal factors involved in the suicidal process that are of significance to any suicide prevention program. It is urged that there be more extensive and comparative research in this important public health problem.

    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.

En este trabajo, en el que se cruzan las miradas de la traductología, la antropología histórica y la filosofía intercultural sobre las fuentes valdivianas, postulamos que es el ethos traductológico de Luis de Valdivia el que, forzando las posibilidades de inteligibilidad mutua, y pese al fracaso inicial de su misión, permite instaurar el modo de negociación que se conoce como parlamentos.Jesuit Luis de Valdivia is known not only for his work as a grammarian, lexicographer and translator, but for his intense diplomatic/political activity as the advocate of the Defensive War policy, in which negotiations mediated by interpreters played a significant role.

    Luis Hidalgo y Carpio (1818-1879) was a notable physician who made important contributions to the field of medicine during his time. Nevertheless, reference sources on the aspect from Hidalgo y Carpio that we would like to emphasize (i.e. as an editor of a medical journal) are scarce since precisely when Hidalgo y Carpio was named President of the Medical Society (later the Academia Nacional de Medicina), in 1987, the publication of the Gaceta Médica de México was temporarily interrupted. Hidalgo y Carpio played a key role as an editor at a time when the medical community of Mexico required a means whereby the scientific achievements could be published and discussed among peers and colleagues. Under Hidalgo y Carpio, the Gaceta Médica de México soon reached a wide audience, not only as a periodical publication but also for the prestige of the Academy that represented.

    Alfonso Luis Herrera (1868-1942) was a Mexican biologist, and significant as the principal promoter of Darwinian thought in that country. However, Herrera's thinking went beyond the evolution of living beings, and extended to the question of the origin of life itself and the place of living phenomena in the larger context of the cosmos. Perhaps more significantly, though now largely forgotten, Herrera was among the first to embark on an experimental program to understand the origin of life, one which may be seen as foundational for later workers, most notably Sidney Fox and Alexander Oparin, and which has been resuscitated recently. We review here the development of Herrera's scientific thought on Darwinism and the origin of life and the context in which it developed.

Tale raccolta di saggi non solo restituisce le linee, i contenuti e le forme di una produzione critica monumentale ma ben mostra l’importante ruolo di studioso e di uomo che il Bellini è stato capace di esercitare, articolando attorno a sé una nutrita scuola, a partire dalla visione della letteratura come rete di dialogo e di scambio. I diversi temi affrontati dai più di cinquantacinque saggi mostrano la straordinaria capacità del Bellini di tessere una proficua rete di relazioni, di studio e di amicizia, e di promuovere l’ispanoamericanismo italiano, sempre attraverso il riconoscimento della letteratura come lezione civile e del buon vivere.
