    The map area includes San Luis and the primarily rural surrounding area. San Luis, the county seat of Costilla County, is the oldest surviving settlement in Colorado (1851). West of the town are San Pedro and San Luis mesas (basalt-covered tablelands), which are horsts with the San Luis fault zone to the east and the southern Sangre de Cristo fault zone to the west. The map also includes the Sanchez graben (part of the larger Culebra graben), a deep structural basin that lies between the San Luis fault zone (on the west) and the central Sangre de Cristo fault zone (on the east). The oldest rocks exposed in the map area are the Pliocene to upper Oligocene basin-fill sediments of the Santa Fe Group, and Pliocene Servilleta Basalt, a regional series of 3.7?4.8 Ma old flood basalts. Landslide deposits and colluvium that rest on sediments of the Santa Fe Group cover the steep margins of the mesas. Rare exposures of the sediment are comprised of siltstones, sandstones, and minor fluvial conglomerates. Most of the low ground surrounding the mesas and in the graben is covered by surficial deposits of Quaternary age. The alluvial deposits are subdivided into three Pleistocene-age units and three Holocene-age units. The oldest Pleistocene gravel (unit Qao) forms extensive coalesced alluvial fan and piedmont surfaces, the largest of which is known as the Costilla Plain. This surface extends west from San Pedro Mesa to the Rio Grande. The primary geologic hazards in the map area are from earthquakes, landslides, and localized flooding. There are three major fault zones in the area (as discussed above), and they all show evidence for late Pleistocene to possible Holocene movement. The landslides may have seismogenic origins; that is, they may be stimulated by strong ground shaking during large earthquakes. Machette and Thompson based this geologic map entirely on new mapping, whereas Drenth supplied geophysical data and interpretations.

  7. 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.

    An investigation of the water resources of the Colorado part of the San Luis Valley was begun in 1966 by the U.S. Geological Survey, in cooperation with the Colorado Water Conservation Board. (See index map, fig. 1). The purpose of the investigation is to provide information for planning and implementing improved water-development and management practices. The major water problems in the San Luis Valley include (1) waterlogging, (2) waste of water by nonbeneficial evapotranspiration, (3) deterioration of ground-water chemical quality, and (4) failure of Colorado to deliver water to New Mexico and Texas in accordance with the Rio Grande Compact. This report describes the hydrologic environment, extent of water-resource development, and some of the problems related to that development. Information presented is based on data collected from 1966 to 1968 and on previous studies. Subsequent reports are planned as the investigation progresses. The San Luis Valley extends about 100 miles from Poncha Pass near the northeast corner of Saguache County, Colo., to a point about 16 miles south of the Colorado-New Mexico State line. The total area is 3,125 square miles, of which about 3,000 are in Colorado. The valley is nearly flat except for the San Luis Hills and a few other small areas. The Colorado part of the San Luis Valley, which is described in this report, has an average altitude of about 7,700 feet. Bounding the valley on the west are the San Juan Mountains and on the east the Sangre de Cristo Mountains. Most of the valley floor is bordered by alluvial fans deposited by streams originating in the mountains, the most extensive being the Rio Grande fan (see block diagram, fig. 2 in pocket). Most of the streamflow is derived from snowmelt from 4,700 square miles of watershed in the surrounding mountains. The northern half of the San Luis Valley is internally drained and is referred to as the closed basin. The lowest part of this area is known locally as the "sump." The

    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. Sin embargo, sólo existen 2 registros de nidos construidos sobre vegetación acuática. Presentamos información adicional de 2 nidos (N1 y N2 construidos en este tipo de hábitat en una población ubicada en la Ciénega de Cabezas en el estado de San Luis Potosí. Los nidos fueron construidos sobre Typha sp., cerca del cauce principal de la ciénega. El N2 se perdió por inundación, en su interior encontramos 32 huevos, los promedios (± SD del largo, ancho y diámetro de 7 huevos fueron 72.6 ± 2.63 mm (rango = 70.0 -75.0 mm, 45.0 ± 2.30 mm (rango = 41.0-48.0 mm, 140.7 ± 2.98 mm (rango = 136.0-145.0 mm, respectivamente. Sugerimos que este tipo de sitios para anidar por parte de C. moreletii está relacionado con la disponibilidad de vegetación acuática, combinado con la ausencia de sitios adecuados en tierra firme.

    2001-01-01

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

    The commercial feasibility of producing between 76 and 189 million liters (20 to 50 million gallons) of ethanol annually in the San Luis Valley, Colorado using geothermal energy as the primary heat source was assessed. The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (IGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstocks for the production of ethanol.

    In October 2011, the U.S. Geological Survey (USGS) contracted airborne magnetic and electromagnetic surveys of the Paradox and San Luis Valleys in southern Colorado, United States. These airborne geophysical surveys provide high-resolution and spatially comprehensive datasets characterizing the resistivity structure of the shallow subsurface of each survey region, accompanied by magnetic-field information over matching areas. These data were collected to provide insight into the distribution of groundwater brine in the Paradox Valley, the extent of clay aquitards in the San Luis Valley, and to improve our understanding of the geologic framework for both regions. This report describes these contracted surveys and releases digital data supplied under contract to the USGS.

  2. 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

    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.

    Mafic to ultramafic metamagmatic rocks are widespread within the western basement of Sierra de San Luis (Eastern Sierras Pampeanas), through a belt of almost 45 km long, from Villa de la Quebrada in the south up to San Francisco del Monte de Oro in the north. The northern area have been studied by Merodio et al. (1978), Kilmurray and Villar (1981), Carugno Duran (1998) and Ortiz Suarez (1999). In the southern area, the detailed structural and metamorphic study revealed the presence of komatiites preserved within amphibolites. These rocks are in association with a supracrustal sequence composed of banded iron formations (BIF), metaquartzites, micaschists and other gneissic rocks (Gonzalez, 2000). Although this basement complex shows a penetrative Famatinian (Early Paleozoic) NNE-SSW trending foliation, remnants of an older NW-SE trending structures are also found (Gonzalez and Llambias, 1998; von Gosen and Prozzi, 1998). As a result of Sm-Nd whole rock analyses of the komatiites and amphibolites from the southern area, we obtained an isochron date of 1502 Ma. This is the first mention of an Early Mesoproterozoic date from the Sierra de San Luis, and hence, in this contribution we discuss its validity, taking into consideration the geological and regional context (au)

    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. 232 Th-series, 238 U-series, 40 K and 137 Cs activity concentrations (AC, Bq kg −1 ) were determined by gamma spectrometry with a high purity Ge detector. 238 U and 234 U ACs were obtained by liquid scintillation and alpha spectrometry with a surface barrier detector. Dating of core sediments was performed applying CRS method to 210 Pb activities. Results were verified by 137 Cs AC. Resulting activity concentrations were compared among corresponding surface and core sediments. High 238 U-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) 234 U/ 238 U and 238 U/ 226 Ra in sediments have values between 0.9–1.2, showing a behavior close to radioactive equilibrium in the entire basin. 232 Th/ 238 U, 228 Ra/ 226 Ra ARs are witnesses of the different geological origin of sediments from San Marcos and Luis L.

    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.

    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.

    The San Luis Basin encompasses the largest structural and hydrologic basin of the Rio Grande rift. On this field trip, we will examine the timing of transition of the San Luis Basin from hydrologically closed, aggrading subbasins to a continuous fluvial system that eroded the basin, formed the Rio Grande gorge, and ultimately, integrated the Rio Grande from Colorado to the Gulf of Mexico. Waning Pleistocene neotectonic activity and onset of major glacial episodes, in particular Marine Isotope Stages 11–2 (~420–14 ka), induced basin fill, spillover, and erosion of the southern San Luis Basin. The combined use of new geologic mapping, fluvial geomorphology, reinterpreted surficial geology of the Taos Plateau, pedogenic relative dating studies, 3He surface exposure dating of basalts, and U-series dating of pedogenic carbonate supports a sequence of events wherein pluvial Lake Alamosa in the northern San Luis Basin overflowed, and began to drain to the south across the closed Sunshine Valley–Costilla Plain region ≤400 ka. By ~200 ka, erosion had cut through topographic highs at Ute Mountain and the Red River fault zone, and began deep-canyon incision across the southern San Luis Basin. Previous studies indicate that prior to 200 ka, the present Rio Grande terminated into a large bolson complex in the vicinity of El Paso, Texas, and systematic, headward erosional processes had subtly integrated discontinuously connected basins along the eastern flank of the Rio Grande rift and southern Rocky Mountains. We propose that the integration of the entire San Luis Basin into the Rio Grande drainage system (~400–200 ka) was the critical event in the formation of the modern Rio Grande, integrating hinterland basins of the Rio Grande rift from El Paso, Texas, north to the San Luis Basin with the Gulf of Mexico. This event dramatically affected basins southeast of El Paso, Texas, across the Chisos Mountains and southeastern Basin and Range province, including the Rio

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

    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.

    Neutron activation analysis, Moessbauer spectroscopy and X-ray diffraction techniques were used to characterize pre-Hispanic potsherds and modern ceramic pottery, samples of which were collected in Tenexco, San Luis Potosi, Mexico. Elementary and spectroscopic analysis showed differences between ancient and modern ceramics. While the modern ceramics studied were practically new and not used at all, the ancient ones were probably used in domestic or ceremonial activities. Besides, the latter were kept buried for a long time, and it is quite probable that their manufacture was also slightly different from that of the former. These assumptions could provide the clues to understand some of the observed differences between the composition of ancient and modern ceramics whose raw materials may have the same origin

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

    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.

    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.

    2000-03-01

    Subduction of the Guadalupe-Magdalena microplate beneath Baja California ended in the middle Miocene, and the last volcanic events in the frontal arc extinguished along the present-day eastern margin of the Baja California peninsula. The San Luis Gonzaga area in the north-central Gulf coast contains one of the younger arc-related volcanic centers in northern Baja California. The volcanic succession contains three sequences. The basal sequence (Group 1) is composed of stratified pyroclastic deposits, up to 500 m thick, and subordinate lava flows. The near-vent facies crop out in tilted fault blocks along the present shoreline, whereas the distal facies are exposed across ˜12 km toward the west and includes epiclastic deposits and at least three ash flow tuffs. This sequence is internally concordant and overlies smooth paleosurface developed on granitic basement, and pinches out across the Gulf escarpment. The Potrero Andesite (Group 2) is a series of dacite to basaltic-andesite lava flows from a shield volcano located ˜15 km west of today's coastline; similar source vents also occurs further south of the San Luis Gonzaga area. A sequence of dacite domes (Group 3) intrudes the near-vent facies of Group 1 and contains subordinate volcanic breccia and minor lava flows that overlie Group 1 sequence. Cross-cutting relationships and the abundance of volcanic breccia associated with the domes suggest that these domes were emplaced as semi-rigid intrusions (spines) with low explosive activity. The San Luis Gonzaga volcanic suite ranges in composition from basaltic andesite to dacite with predominant plagioclase and pyroxene and variable amounts of hornblende. Trace-element patterns indicate calc-alkaline to mildly alkaline magmas with high Ba and low Nb contents. Incompatible-element ratios and mineralogical characteristics suggest different magma batches and/or different amount of crustal assimilation for the three sequences that produced contrasting eruptive styles.

    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

    Time-domain electromagnetic (TEM) soundings were made near Great Sand Dunes National Park and Preserve in the San Luis Valley of southern Colorado to obtain subsurface information of use to hydrologic modeling. Seventeen soundings were made to the east and north of the sand dunes. Using a small loop TEM system, maximum exploration depths of about 75 to 150 m were obtained. In general, layered earth interpretations of the data found that resistivity decreases with depth. Comparison of soundings with geologic logs from nearby wells found that zones logged as having increased clay content usually corresponded with a significant resistivity decrease in the TEM determined model. This result supports the use of TEM soundings to map the location of the top of the clay unit deposited at the bottom of the ancient Lake Alamosa that filled the San Luis Valley from Pliocene to middle Pleistocene time.

    The National Park Sierra de las Quijadas is located to 120 km to the northwest of the Province of San Luis, Argentina. The study area is of 24,000 hectares, that correspond to 32 % of the total surface, this surface covers the totality with the Potrero de la Aguada and the next zones, the same one was selected because it conforms at the present time the zone of greater frequency of visitors within the Park. The objective of this work is centered in the obtaining of the Total Quality of the Landscape, having compared the demand of beauty to the rest of the other natural resources, to be able to make proposals to improve the Plan of Handling that takes ahead the Administration of National Parks. The used Methodology is the described one by Cendrero et. al. (1987), it is an indirect valuation that is carried out through the components of the landscape and allows to determine the Intrinsic Visual Quality and the Fragility of each one of the Environmental Units in which the park is divided. This analysis allowed to determine 2 Total Qualities of Landscape, that have been mapped using aerial photography equipment and materials and SIG, with field control. This investigation is developed within the Project of Investigation Geology of the Neogeno and Cuaternario of the Mountain range of San Luis, Faculty of Sciences Physical, Mathematics and Natural - National University of San Luis, Argentina.

    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.

    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.

  14. Problems related to water quality and algal control in Lopez Reservoir, San Luis Obispo County, California

    A study to determine the present enrichment status of Liopez Reservoir in San Luis Obispo county, California, and to evaluate copper sulfate algal treatment found that stratification in the reservoir regulates nutrient release and that algal control has been ineffective. Nuisance algal blooms, particularly from March to June, have been a problem in the warm multipurpose reservoir since it was initially filled following intense storms in 1968-69. The cyanophyte Anabaena unispora has been dominant; cospecies are the diatoms Stephanodiscus astraea and Cyclotella operculata, and the chlorophytes Pediastrum deplex and Sphaerocystis schroeteri. During an A. unispora bloom in May 1972 the total lake surface cell count was nearly 100,000 cells/ml. Thermal stratification from late spring through autumn results in oxygen deficiency in the hypolimnion and metalimnion caused by bacterial oxidation of organic detritus. The anaerobic conditions favor chemical reduction of organic matter, which constitute 10-14% of the sediment. As algae die, sink to the bottom, and decompose, nutrients are released to the hypolimnion , and with the autumn overturn are spread to the epilimnion. Algal blooms not only hamper recreation, but through depletion of dissolved oxygen in the epilimnion may have caused periodic fishkills. Copper sulfate mixed with sodium citrate and applied at 1.10-1.73 lbs/acre has not significantly reduced algal growth; a method for determining correct dosage is presented. (Lynch-Wisconsin)

    The outcroping deposits in the ravines of the Conlara River are dominated by silt with subordinated and variable percentages of sand and clays. In the section that is described, at the south of the town of Santa Rosa del Conlara, these materials have been deposited responding generally climatic changing conditions. The base of the profile, assigned to the late Pleistocene, contains extint fauna of the Lujanense and a datation of 8950 B.P., and it is represented by fluvial sandy gravels. The overlaying succession, assigned to the Holocene, shows an intercalation of horizons generated by eolic-loessic deposits and deposits with development of pedogenetic processes. The whole succession shows characteristic of corresponding to a vegetated plain, next to the river flood plain. The discriminated horizons are the result of a detailed sampling and the representation of range parameters of the same ones, in function of the depth, this last one oscillates between 6 and 8 meters. The quaternary deposits of the region, support indistinctly as on the crystalline basement of San Luis range, as on the calcretes assigned to the Neogene [es

  16. 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.

    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.

    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

    Ecological studies of species, such as the stomach content analysis, allow us to recognize different trophic groups, the importance of trophic levels and the interrelationships among species and other members of the community. In this investigation, we studied food habits, feeding variation and trophic relationships of the fishes present in streams of the Corral de San Luis drainage, Tubará, Atlántico Department, a part of the lower Magdalena River Basin in Colombian Caribbean. Fish samples of Awaous banana, Agonostomus monticola, Andinoacara latifrons, Hyphessobrycon proteus, Poecilia gillii, Gobiomorus dormitor and Synbranchus marmoratus were obtained using a seine (2x5 m, mesh 0.5 cm), from November 2012 to October 2013. To analyze their stomach contents, we used numeric (% N), volumetric (% V) and frequency of occurrence (% FO) methods, an emptiness coefficient (C.V), index of food item importance (I.A). Besides, physical and chemical habitat parameters were recorded on site. Information obtained was processed using multivariate statistical analysis, ecological indices, and null models: canonical correspondence analysis (CCA), principal component analysis (PCA), trophic niche amplitude (Shannon-Weaver H´) and trophic overlap (Morisita-Horn). We observed significant differences on food resources consumption (K-W= 20.86; ptrophic axis, with respect to shared food items, and that the segregation was not influenced or generated by competition. The Morisita-Horn index showed false trophic overlap (similarity of about 80 %) between A. banana and P. gillii. The first component of the PCA analysis was explained mainly by phytoplankton, and component two was correlated with items of animal origin. The fishes associated with PC1 were P. gillii and A. banana, with high ingestion values of microalgae. PC2 was explained by A. monticola with high numbers of food items of animal origin. The group of fishes studied behaved as an assemblage; given that the trophic

    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 Sunshine Valley-Costilla Plain, a structural subbasin of the greater San Luis Basin of the northern Rio Grande rift, is bounded to the north and south by the San Luis Hills and the Red River fault zone, respectively. Surficial mapping, neotectonic investigations, geochronology, and geophysics demonstrate that the structural, volcanic, and geomorphic evolution of the basin involves the intermingling of climatic cycles and spatially and temporally varying tectonic activity of the Rio Grande rift system. Tectonic activity has transferred between range-bounding and intrabasin faults creating relict landforms of higher tectonic-activity rates along the mountain-piedmont junction. Pliocene–Pleistocene average long-term slip rates along the southern Sangre de Cristo fault zone range between 0.1 and 0.2 mm/year with late Pleistocene slip rates approximately half (0.06 mm/year) of the longer Quaternary slip rate. During the late Pleistocene, climatic influences have been dominant over tectonic influences on mountain-front geomorphic processes. Geomorphic evidence suggests that this once-closed subbasin was integrated into the Rio Grande prior to the integration of the once-closed northern San Luis Basin, north of the San Luis Hills, Colorado; however, deep canyon incision, north of the Red River and south of the San Luis Hills, initiated relatively coeval to the integration of the northern San Luis Basin.Long-term projections of slip rates applied to a 1.6 km basin depth defined from geophysical modeling suggests that rifting initiated within this subbasin between 20 and 10 Ma. Geologic mapping and geophysical interpretations reveal a complex network of northwest-, northeast-, and north-south–trending faults. Northwest- and northeast-trending faults show dual polarity and are crosscut by north-south– trending faults. This structural model possibly provides an analog for how some intracontinental rift structures evolve through time.

    Here we present archosauriform remains from 'Abra de los Colorados', a fossiliferous locality at Sierra de Guayaguas, NW San Luis Province. Two fossiliferous levels were identified in outcrops of the Quebrada del Barro Formation (Norian), which represent the southernmost outcrops of the Marayes-El Carrizal Basin. These levels are composed by massive muddy lithofacies, interpreted as floodplain deposits. The specimens consist of one incomplete maxilla (MIC-V718), one caudal vertebra (MIC-V719), one metatarsal (MIC-V720) and one indeterminate appendicular bone (MIC-V721). The materials can be assigned to Archosauriformes but the fragmentary nature and lack of unambiguous synapomorphies preclude a more precise taxomic assignment. The maxilla is remarkably large and robust and represents the posterior process. It preserved one partially erupted tooth with ziphodont morphology. This bone shows some anatomical traits and size match with 'rauisuchians' and theropods. MIC-V719 corresponds to a proximal caudal vertebra. It has a high centrum, a ventral longitudinal furrow, expanded articular processes for the chevrons, a posteriorly displaced diapophysis located below the level of the prezygapophyses, and short prezygapophyses. This vertebra would be from an indeterminate archosauriform. MIC-V720 presents a cylindrical diaphysis, with a well-developed distal trochlea, which present resemblances with metatarsals of theropods, pseudosuchians, and silesaurids, although the size matches better with theropods. MIC-V721 has a slender diaphysis and a convex triangular articular surface, and corresponds to an indeterminate archosauriform. Despite being fragmentary, these materials indicate the presence of a diverse archosauriforms association from Late Triassic beds of San Luis. Thus, they add to the faunal assemblage recently reported from this basin at San Juan Province, which is much rich and diverse than the coeval paleofauna well known from Los Colorados Formation in the

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.

The L. monocytogenes isolates from two patients belonged to PCR group IVb (including serovar 4b strains and to PCR group IIb (including serovar 1/2b strains in the third patient. Listeriosis, especially the maternal-fetal presentation, is still rare in Argentina for unknown reasons. Our data can be used in the future as an epidemiological survey.En el presente estudio se describen tres casos de infección neonatal por Listeria monocytogenes, dos de inicio temprano y uno tardío, diagnosticados en San Luis, Argentina, entre noviembre de 1996 y diciembre de 2006. En uno de los pacientes afectados por listeriosis temprana, la meningitis condujo a la hidrocefalia secundaria. En los otros recién nacidos, la evolución clínica fue favorable después de la administración de un rápido y adecuado tratamiento. Los aislamientos de L. monocytogenes de dos pacientes pertenecieron al grupo IVb (serovar 4b y el del tercer paciente al grupo IIB (serovar 1/2b según la técnica de PCR. La listeriosis es, por razones que se desconocen, una enfermedad rara en Argentina, especialmente la presentación materno-fetal. Los resultados presentados aquí podrán ser utilizados en un futuro con fines epidemiológicos.

    Full Text Available El trabajo pretende contribuir, desde la perspectiva de la organización de la tecnología, al conocimiento de las ocupaciones cazadoras-recolectoras que habitaron las inmediaciones de la Sierra de la Estanzuela, en la provincia de San Luis, Argentina. Se explican cómo fueron las secuencias de producción de herramientas en los sitios de la localidad arqueológica Estancia La Suiza, a partir del análisis de los materiales líticos recuperados en excavación y prospecciones sistemáticas. Las metodologías propuestas para abordar este estudio corresponden al análisis nodular y más específicamente a una combinación del análisis tipológico y no tipológico. Los resultados permiten interpretar que en esta localidad hubo un uso diferencial del espacio, particularmente en dos sitios que son Estancia La Suiza 2 y Estancia La Suiza 3. Abstract This paper aims at gaining insight, from the angle of technological organization, into the hunter-gatherer communities that dwelled in the surrounding areas of Sierras de la Estanzuela, in the province of San Luis, Argentina. The sequence of tool development in the archaeological site of Estancia La Suiza is described from analysis of lithic materials from excavation and systematic surveys. The methods adopted for conducting this study form part of Minimal Nodule analysis (MANA and more specifically a combination of typological and non-typological analysis. Results indicate that this site evidences a differential use of space, more specifically found in Estancia La Suiza 2 and Estancia La Suiza 3.

  14. 76 FR 41811 - Kellaway Proposed Low-Effect Habitat Conservation Plan for the Morro Shoulderband Snail, San Luis...

    Science.gov (United States)

    2011-07-15

    ...We, the U.S. Fish and Wildlife Service (Service), have received an application from Thomas R. Kellaway and Doris J. Redmon (applicants) for a 5-year incidental take permit under the Endangered Species Act of 1973, as amended (Act). The application addresses the potential for ``take'' of the Federally endangered Morro shoulderband snail (Helminthoglypta walkeriana) incidental to the construction and occupation of two single-family residences, one on each of two legal parcels occupied by the species in the community of Los Osos, San Luis Obispo County, California. The applicants would implement a conservation program to minimize and mitigate project activities as described in their low-effect habitat conservation plan (plan). We invite comments from the public on the application, which includes the Kellaway Low-Effect Habitat Conservation Plan for the Morro Shoulderband Snail (HCP), which has been determined to be eligible for a Categorical Exclusion under the National Environmental Policy Act of 1969, as amended (NEPA).

    Several species of pathogenic Acanthamoeba cause infections to humans, but amoebic keratitis is more frequently found than any other due to the increasing number of contact lens wearers in the world. Cysts and trophozoites of these amebas are airborne and may pollute water from the air. We investigated the proportion of pathogenic Acanthamoeba from the atmosphere of the city of San Luis Potosi. Samples were taken by the impinger method, every month during one year. We isolated 23 strains of Acanthamoeba, 61% of them were non-pathogenic, 31% were non-pathogenic with invasive capacity and 8% were pathogenic to mice. Almost 40% of these strains represent danger of infections to humans. The isolations were more abundant during the dry season in the south (urban) and west (suburban) stations, which means that the sanitary conditions around stands may enhance the proportion of pathogenic strains in the surroundings.

    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.

    To assess the utilization of sterilizing equipment used by dentists, and verification of sterilization using biological indicators. A cross-sectional study was conducted in 1999-2000, among 130 (65%) dentists having sterilizing equipment, at Facultad de Estomatología, Universidad Autónoma de San Luis Potosí and Colegio Dental Potosino. Biological indicators for sterilization containing Bacillus subtilis and Bacillus stearothermophilus were used. Thirty autoclaves and 100 dry-heat sterilizers were evaluated: 23 (17.7%) of them showed bacterial growth. Twenty-one (16.1%) dentists already were using biological indicators to verify their sterilizing equipment. Both sterilization methods were found to allow bacterial growth with similar frequencies (p = > 0.66). Few dentists verify the quality of sterilization process through biological indicators; bacterial growth and failure of sterilization were evidenced.

    To develop a predictive dynamic model to generate and analyse the future status of the incidence rate of ischaemic heart disease in a population of 25 years and over in Mexico, according to the variation in time of some risk factors. Retrospective ecological study performed during the period 2013-2015, in San Luis Potosí City, Mexico. Secondary databases that corresponded to the years 2000, 2005, and 2010, were used along with official indicators of the 58 municipalities of the state of San Luis Potosí. Eight indicators were analysed at municipality level, using principal components analysis, structural equation modelling, dynamic modelling, and simulation software methods. Three components were extracted, which together explained 80.43% of the total variance of the official indicators used. The second component had a weight of 16.36 units that favoured an increase of the disease analysed. This component was integrated only by the indicator AGE 60-64 and the expected stage of it increasing. The structural model confirmed that the indicators explain 42% of the variation of this disease. The possible stages for the years 2015, 2020, and 2025 are 195.7, 240.7, and 298.0, respectively for every 100,000 inhabitants aged 25 and over. An exponential increase in the incidence rate of ischaemic heart disease is expected, with the age of 60-64 years being identified as the highest risk factor.

    1985-01-01

    In November 1984, 84 wells and 1 spring in the Bonsall area of the San Luis Rey River valley were inventoried by U.S. Geological Survey personnel. Depth to water in 38 wells ranged from 1.3 to 38 ft and 23 wells had depths to water less than 10 feet. Dissolved solids concentration of water from 29 wells and 1 spring sampled in autumn 1983 and spring 1984 ranged from 574 to 2,370 mgs/L. Groundwater with a dissolved solids concentration less than 1,000 mgs/L was generally restricted to the eastern part of the aquifer. The total volume of alluvial fill in the Bonsall area is 113,000 acre-feet; the amount of groundwater storage available in the alluvial aquifer is 18,000 acre-feet. The alluvial aquifer is, in part, surrounded and underlain by colluvium and weathered crystalline rock that add some additional groundwater storage capacity to the system. Data in this report are presented on five maps showing well locations , thickness of alluvial fill, water level contours in November 1983 and hydrographs of selected wells, groundwater quality in spring 1960 and graphs showing changes in dissolved solids concentrations of water from selected wells with time, and groundwater quality in spring 1984. This report is part of a larger cooperative project between the Rainbow Municipal Irrigation District and the U.S. Geological Survey. The purpose of the larger project is to develop an appropriate groundwater management plan for the Bonsall area of the San Luis Rey River valley. (USGS)

    We 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 2017. Surveys were conducted from April 13 to July 11 (LBVI) and from May 16 to July 28 (SWFL). We found 146 LBVI territories, at least 107 of which were occupied by pairs. Five additional transient LBVIs were detected. LBVIs used five different habitat types in the survey area: mixed willow, willow-cottonwood, willow-sycamore, riparian scrub, and upland scrub. Forty-four percent of the LBVIs occurred in habitat characterized as mixed willow and 89 percent of the LBVI territories occurred in areas with greater than 50 percent native plant cover. Of 16 banded LBVIs detected in the survey area, 8 had been given full color-band combinations prior to 2017. Four other LBVIs with single (natal) federal bands were recaptured and banded in 2017. Three LBVIs with single dark blue federal bands indicating that they were banded as nestlings on the lower San Luis Rey River and one LBVI with a single gold federal band indicating that it was banded as a nestling on Marine Corps Base Camp Pendleton (MCBCP) could not be recaptured for identification. One banded LBVI emigrated from the middle San Luis Rey River to the lower San Luis Rey River in 2017.One resident SWFL territory and one transient Willow Flycatcher of unknown subspecies (WIFL) were observed in the survey area in 2017. The resident SWFL territory, which was comprised of mixed willow habitat (5–50 percent native plant cover), was occupied by a single male from May 22 to June 21, 2017. No evidence of pairing or nesting activity was observed. The SWFL male was banded with a full color-combination indicating that he was originally banded as a nestling on the middle San Luis Rey River in 2014 and successfully bred in the survey area in 2016

    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.

    2014-12-01

    Comprehensive paleomagnetic study of the Oligocene-Miocene sequence of lithological units from the San Luis Potosí volcanic field in central Mexico was accomplished to set up the magnetostratigraphic record. Two hundred and one oriented standard paleomagnetic cores corresponding to twenty-eight paleomagnetic sites were collected from all units. Rock-magnetic properties are characteristic for each unit. Isothermal remanent magnetization acquisition curves and continuous susceptibility vs. temperature experiments point from low to medium-Ti content in titanomagnetite as the main opaque magnetic minerals, presumably result from oxy-exsolution processes during the initial flow cooling. Opaque mineral microscopy supports this assumption. Unblocking temperature and hysteresis parameters suggests predominance of pseudo-single domain magnetic grain size. Thermal and alternating field demagnetizations show mostly well-defined univectorial magnetizations. Most sites present a mean direction with small angular dispersion. The overall mean direction (N=10, Dec=1.1°, Inc=34.1°, k=531 and α95=2.1°) is characterized by small angular dispersion and inclination close to dipolar value for the locality. Anisotropy of magnetic susceptibility lineation match the geologically inferred flow direction.

    1979-01-01

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

    This investigation was undertaken to determine the concentrations of lead in bird blood samples from a mining region in central Mexico and to compare concentrations among several different feeding guilds. The study took place in the Mexican state of San Luis Potosi in a region known as "Villa de la Paz." This is one of the most intensely exploited mining regions in central Mexico and has been actively mined for over four centuries. Lead concentrations from bird blood samples taken from four polluted sites were significantly higher than those from a control, unpolluted site (F = 6.3, P birds from a highly polluted site were higher than those from a site that has intermediate pollution levels (P birds had significantly lower lead concentrations compared to granivores, frugivores-insectivores, and omnivores (F = 4.86, P = 0.004), and a large proportion of all individuals had blood lead concentrations indicative of low, sub-lethal toxic effects. Finally, in two polluted sites, remarkably small numbers of insectivore-frugivores, and granivores were trapped, and in one polluted site a large number of insectivores was trapped (X(2) = 29.9, P = 0.03), and no differences in proportions of migrants and non-migrants were found among sampling sites (X(2) = 0.6, P = 0.96). To date, it has not been determined to what extent constant exposure to these levels of pollution can influence health at the individual level, lifespan, and, therefore, population demography of birds from this region.

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

    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.

    The presence of arsenic (As) in agricultural food products is a matter of concern because it can cause adverse health effects at low concentrations. Agricultural-product intake constitutes a principal source for As exposure in humans. In this study, the contribution of the chemical-soil parameters in As accumulation and translocation in the maize crop from a mining area of San Luis Potosi was evaluated. The total arsenic concentration and arsenic speciation were determined by HG-AFS and IC-HG-AFS, respectively. The data analysis was conducted by cluster analysis (CA) and principal component analysis (PCA). The soil pH presented a negative correlation with the accumulated As in each maize plant part, and parameters such as iron (Fe) and manganese (Mn) presented a higher correlation with the As translocation in maize. Thus, the metabolic stress in maize may induce organic acid exudation leading a higher As bioavailability. A high As inorganic/organic ratio in edible maize plant tissues suggests a substantial risk of poisoning by this metalloid. Careful attention to the chemical changes in the rhizosphere of the agricultural zones that can affect As transfer through the food chain could reduce the As-intoxication risk of maize consumers.

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

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

    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.

    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.

    Urbanization can cause significant changes in the integrity of fluvial ecosystems, which makes it necessary to assess environmental conditions of areas where population growth rates are high. A study of the environmental quality of Chorrillos River (San Luis-Argentina) and its tributaries was carried out in order to evaluate the potential effect of an urbanization gradient. Six sites were sampled along the main course and tributaries of the river. Urbanization variables were measured and included to calculate an Urbanization Index. Physical–chemical analyses were performed in water samples to evaluate water quality through the use of a simplified index of water quality (SIWQ). Plants, macroinvertebrates, and amphibians metrics were used to assess the biological state of the studied sites. The Urbanization Index varied significantly between sites and was significantly correlated to the SIWQ. However, no significant correlations were found between SIWQ and macroinvertebrates and amphibians variables. Water quality of Chorrillos River and its tributaries is good, but it is affected by anthropic influences as reflected by the declining of SIWQ values. Although biological sampling constitutes an important tool in the assessment of water quality of rivers, in this report biological results were not conclusive.

    Anisotropy of magnetic susceptibility (AMS) was selected as the key technique to find the source of the widespread Cantera Ignimbrite and to seek its possible relationship with the San Luis Potosí Caldera. Eighteen sites (372 specimens from 155 cores) from the Oligocene Cantera Ignimbrite were sampled. AMS was measured on a KLY2 Kappabridge. AMS data were processed with Anisoft 3 software using Jelinek statistics as well as `SpheriStat' principal components and density distribution. Mean susceptibilities range from 290 to 5026 × 10-6 SI (average = 2526 × 10-6 SI). The anisotropy degree ( P j) ranges from 1.005 to 1.055, with only one site displaying a value of 1.134 ( P j average = 1.031). AMS ellipsoid shapes are mostly oblate, with the T-factor ranging from 0.843 to 0.144 ( T average = 0.529), although one site is mainly prolate ( T = -0.005), and three additional sites have an important proportion of prolate specimens. Magnetic fabrics of most sites shows k3 axes around nearly circular distributions and k 1- k 2 axes around elongated-girdle distributions defining sub-horizontal foliation planes; exceptions to this are related to sites with a significant percentage of prolate specimens. Flow directions inferred from AMS analysis indicate several ignimbrite sources located along selected NW-SE linear features (faults and fractures such as El Potosino Fault) as well as along the rim of the caldera structure. The geometry of volcanic outcrops, the NW-SE faulting-fracture system, as well as the AMS results suggest that this is a caldera structure resembling the trapdoor-type (Lipman, 1997).

    Acute respiratory infections are a leading cause of morbidity and mortality worldwide. Starting in 2009, pandemic influenza A(H1N1) 2009 virus has become one of the leading respiratory pathogens worldwide. However, the overall impact of this virus as a cause of mortality has not been clearly defined. To determine the impact of pandemic influenza A(H1N1) 2009 on mortality in a Mexican population. We assessed the impact of pandemic influenza virus on mortality during the first and second outbreaks in San Luis Potosí, Mexico, and compared it to mortality associated with seasonal influenza and respiratory syncytial virus (RSV) during the previous winter seasons. We estimated that, on average, 8·1% of all deaths that occurred during the 2003-2009 seasons were attributable to influenza and RSV. During the first pandemic influenza A(H1N1) 2009 outbreak, there was an increase in mortality in persons 5-59 years of age, but not during the second outbreak (Fall of 2009). Overall, pandemic influenza A (H1N1) 2009 outbreaks had similar effects on mortality to those associated with seasonal influenza virus epidemics. The impact of influenza A(H1N1) 2009 virus on mortality during the first year of the pandemic was similar to that observed for seasonal influenza. The establishment of real-time surveillance systems capable of integrating virological, morbidity, and mortality data may result in the timely identification of outbreaks so as to allow for the institution of appropriate control measures to reduce the impact of emerging pathogens on the population. © 2010 Blackwell Publishing Ltd.

    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.

    We used paleomagnetic and structural data to investigate the late Eocene-Oligocene tectonic evolution of the Mesa Central area in Mexico. The Mesa Central was affected by NW-trending faults (Tepehuanes-San Luis fault system) coeval with a Late Eocene-Oligocene ignimbrite flare-up and by post-27 Ma NNE-trending grabens related to the Basin and Range. We obtained reliable paleomagnetic directions from 61 sites within the Late Eocene-Oligocene volcanic series (~ 30 to ~ 27 Ma) of the San Luis Potosí volcanic field and Sierra de Guanajuato. For each site we also measured the anisotropy of magnetic susceptibility (AMS). Tilt corrections were made using AMS data for 33 sites where in situ bedding measurements were not available. Paleomagnetic directions indicate counterclockwise rotations of about 10° with respect to stable North America after 30-25 Ma. Structural data suggest that the volcanic succession was mainly affected by normal faults. However, we also found evidences for oblique or horizontal striae showing a left-lateral component along NW-trending faults and a right lateral component along NE-trending faults. Both motions are consistent with a N-S extension oblique to the Tepehuanes-San Luis fault system. Previous paleomagnetic studies in northern and southern Mexico show the prevalence of minor left-lateral shear components along regional-scale transpressional and transtensional lineaments. Our paleomagnetic data may reflect thus small vertical-axis rotations related to a minor shear component coeval with the Oligocene intra-arc extension in central Mexico.

    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

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

    Science.gov (United States)

    Mix, Ken

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

  2. Importance of the vertical component of groundwater flow: a hydrogeochemical approach in the valley of San Luis Potosi, Mexico

    Fractured volcanics exert a control on groundwater flow in the San Luis Potosi (SLP) valley. The chemical composition and temperature of water pumped from boreholes partially penetrating the fractured volcanics indicate that the produced water originates from an upward vertical flow. Most of the thermal groundwater has been detected in areas related to regional faults and lineaments. Intensive and uncontrolled pumping from the upper {1}/{4} of the aquifer (total depth > 1500 m) causes the rise of water from a deep regional flow system that mixes with the shallower waters. The deep waters contain high fluoride concentrations that contaminate the mixture and cause substantial health related effects. The recharge controls on the regional flow system require further research; however, hydrogeochemical evidence supports the view that the origin of this recharge is limited to the western bounding Sierra Madre Occidental. Higher levels of dissolved Na +, Li +, F - (and SO 4-2) derived from Tertiary volcanics have been introduced into the exploited region; the concentrations indicate lengthy and deep circulation flow. Li + concentration was used as an indicator of groundwater residence time, and therefore of the length of the groundwater flow path. Hydrogeochemical interpretation indicates the presence of three flow systems: a shallow local one controlled by a clay layer that subcrops most of the valley floor, an intermediate system in which water infiltrates just beyond the boundary of the clay layer, and a deep regional system which originates outside the surface catchment. The local and intermediate systems circulate through materials with comparatively low hydraulic conductivity. Low Cl - concentrations suggest rapid flow in the regional system. Concentrations of Li + and F - can be used to calculate percentages of waters in mixtures of regional and intermediate flows. Concentrations of Na +, Ca 2+ and SO 4-2 appear to be controlled by water-rock reactions

    To determine the experience, prevalence and severity of dental caries, as well as the Significant Caries Index (SiC) and the treatment needs (TN) in schoolchildren aged six to twelve years. Equally, to estimate the effect of caries in primary dentition on caries in permanent dentition. A cross-sectional study was realized in 3865 schoolchildren from San Luis Potosí City, Mexico. Subjects were clinically evaluated by three standardized examiners (kappa > 0.85). For detection of caries was employed the WHO's criteria for primary (dmft) and permanent (DMFT) dentitions. In the statistical analyzes non-parametric test and logistic regression were used. Mean of age was 8.69 +/- 1.79 and 51.3% were women. In the primary dentition: dmft index was 1.88 +/- 2.34 and the caries prevalence (dmft >0) of 56.8%. In account to severity 22.0% and 5.6% have dmft >3 and dmft >6, respectively. In children of six years, the caries prevalence was 56.0% and the SiC of 5.45. In the permanent dentition: DMFT index was 1.11 +/- 2.03 and the caries prevalence (DMFT >0) of 36.8%. In account to severity 11.8% and 2.8% have DMFT >3 and DMFT >6, respectively. In children of twelve years, the DMFT index caries 4.14 +/- 4.15 and the SiC of 9.15. The TN index was of 88.5% for primary dentition and 93.6% for the permanent. In logistic regression we observed associated to caries prevalence in permanent dentition; presence of caries in primary dentition (OR = 6.37; p Caries prevalence to six years old and DMFT index to twelve years old were highest to values established by WHO. Caries severity in the primary dentition was two times than observed in the permanent dentition. High TN in both dentitions was observed. Presence of caries in primary dentition was a strong risk indicator for to present caries in permanent dentition.

    The Great Sand Dunes National Park and Preserve (GSDNPP) in the San Luis Valley, Colorado, contains a variety of eolian landforms that reflect Holocene drought variability. The most spectacular is a dune mass banked against the Sangre de Cristo Mountains, which is fronted by an extensive sand sheet with stabilized parabolic dunes. Stratigraphic exposures of parabolic dunes and associated luminescence dating of quartz grains by single-aliquot regeneration (SAR) protocols indicate eolian deposition of unknown magnitude occurred ca. 1290-940, 715 ± 80, 320 ± 30, and 200-120 yr ago and in the 20th century. There are 11 drought intervals inferred from the tree-ring record in the past 1300 yr at GSDNPP potentially associated with dune movement, though only five eolian depositional events are currently recognized in the stratigraphic record. There is evidence for eolian transport associated with dune movement in the 13th century, which may coincide with the "Great Drought", a 26-yr-long dry interval identified in the tree ring record, and associated with migration of Anasazi people from the Four Corners areas to wetter areas in southern New Mexico. This nascent chronology indicates that the transport of eolian sand across San Luis Valley was episodic in the late Holocene with appreciable dune migration in the 8th, 10-13th, and 19th centuries, which ultimately nourished the dune mass against the Sangre de Cristo Mountains.

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

    Full Text Available 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.

    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.

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.

    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.

    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.

    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.

  10. Isotope and trace element systematics in a spinel-lherzolite-bearing suite of basanitic volcanic rocks from San Luis Potosi, Mexico

    Lherzolite-bearing basanitic magmas of Quaternary age have erupted to form maars, lava/cinder cones and lava flows in two volcanic fields (Ventura and Santo Domingo) in the central Mexican state of San Luis Potosi. The systematics of the radiogenic isotopes of Sr, Nd, and Pb and the relationship between these parameters and elemental compositions are used to investigate the petrogenesis of the volcanic rocks and the nature of their mantle sources. Sr and Nd isotopic data are presented for 19 basanitic rocks, 5 kaersutites, and 6 lherzolitic xenoliths; Pb data presented for the same 19 volcanic rocks and 4 of the 5 kaersutites. The isotopic compositions for all of these samples fall within the mantle range defined by MORBs and OIBs. The basanites generally plot within the OIB field on isotopic diagrams; most of the kaersutites are displaced to slightly more-depleted (i.e. MORB-like) values than the volcanic samples and the xenoliths, with one exception, are significantly more-depleted than either of these sample-types. As crustal contamination is considered unlikely for most of the volcanic samples, these trends are thought to arise from mixing multiple mantle components. The absence of similar isotopic elemental relationships for Epsilon Nd and the lack of correlation between {sup 206}Pb/{sup 204}Pb and the other Pb isotopes require a mixture of at least three mantle reservoirs: a depleted reservoir analogous to that of the MORBs, a St. Helena-type component, and a third component, which primarily affects Sr and {sup 208}Pb/{sup 204}Pb composition. This third component carries relatively radiogenic Sr and {sup 208}Pb/{sup 204}Pb and appears to be correlated with the degree of melting.

    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

    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.

    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.

    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.

    Pedogenic carbonate horizons are abundant in semi-arid and arid regions worldwide and within the geologic record. They present a widely distributed archive of past environmental conditions, driven by global climate or tectonically-controlled elevation changes. Oxygen and carbon isotopes in calcite-rich nodules and clast rinds are widely-applied indicators of past soil water and CO2 composition linked to changing precipitation and plant communities. The temperature of carbonate formation, however, provides key constraint on past water/CO2 values and elucidate why they may have changed in the past. Clumped isotope thermometry can provide this constraint and additional climate information, given the carbonate forming system is well understood. We present preliminary clumped isotope (Δ47) temperatures for Holocene soil carbonates, constrained by 14C and U-Th disequilibrium dating, compared with two years of in situ soil temperature data to better understand the mechanism and seasonality of carbonate formation in the San Luis Valley region of the southern Rocky Mountains. Five temperature-monitoring sites ranging in elevation (1940-2450 m) and latitude (36.2-37.9°N) were installed in a variety of settings (range front, valley center, and canyon). The resulting records show indistinguishable seasonal temperature variations at >60 cm depth. This suggests Δ47 temperatures should be comparable at sites across the region. Temperatures based on Δ47 measurements of Holocene (>1.8 to 11.0 ka BP) carbonates at these sites yield consistent inter-site temperatures of 10±4°C, which are similar to modern springtime soil temperatures at depth. This seasonality matches previous results of isotopic modeling at sites further south along the Rio Grande corridor. Temperatures during March to May show multiple, abrupt warming and cooling cycles on weekly timescales caused by wetting and drying of the soil during spring precipitation events. This may drive carbonate precipitation

    Viral infections and the burden of high-grade intraepithelial neoplasias (HIN) and invasive carcinomas (IC) associated to infections by human papillomavirus (HPV) types may be prevented by type-specific anti-HPV vaccines. This study determined the prevalence of HPV types in non-cervical HIN and IC diagnosed from 1999 to 2011 at a general hospital in San Luis Potosí, Mexico. Review of the 67 formaldehyde-fixed paraffin-embedded non-cervical specimens initially diagnosed as HIN (n = 28) or IC (n = 39) confirmed the presence of tumor tissue in 63 of them and changed the diagnosis of 24 from HIN to low-grade intraepithelial neoplasias, that were excluded from the study. HPV DNA was detected with the SPF10-DNA enzyme immunoassay in the 39 cases included, and viral types in the HPV-positive tumors were identified with the INNO-LiPA linear probe array. Among the cases included, four HIN were located in the vagina (n = 3) and vulva (n = 1), and 35 IC in the oral cavity (n = 19), penis (n = 8), vagina (n = 7) and vulva (n = 1). There were 13 HPV-positive cases from the vagina (n = 7), vulva (n = 1), penis (n = 1) and oral cavity (n = 1). The viral types identified were the high-risk types HPV16 in the vagina (n = 3) and vulva (n = 3), HPV45 in the vagina (n = 2), HPV59 in the vagina (n = 1) and penis (n = 1), HPV33 in the vagina (n = 1),and HPV35 in the tongue(n = 1); and the low-risk types HPV54 in the vagina (n = 1), and HPV11 in the vulva (n = 1). Five high-risk viral types (HPV16, 45, 59, 33 and 35) and two low-risk types (HPV11 and 54) infect one third of the non-cervical HIN and IC included. Most infections are by a single HPV high-risk type, the most prevalent one being HPV16. Vagina is the most frequent location of the HPV-positive tumors. Vaccination against HPV16 and HPV18 could have prevented around half of the HPV-positive tumors.

    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.

    We report the results from the March 2, 2017, Ancho Canyon RF collection. While bright electromagnetic signals were seen nearby the firing point, there were no detections of signals from the explosively-fired fuse at a collection point about 570m distant on the East Mesa. However, "liveness" tests of the East Mesa data acquisition system and checks of the timing both suggest that the collection system was working correctly. We examine possible reasons for the lack of detection. Principal among these is that the impulsive signal may be small compared to the radio frequency background on the East Mesa.

    We determined the prevalence of anti-rubella antibodies in 100 serum samples from pregnant women who attended routine examination at a private institution in the city of Córdoba, and in 100 serum samples from women of gestational age, 42 of whom were pregnant, attending health centres in the city of Villa Mercedes, province of San Luis. IgG antibodies against parvovirus 819 were also determined in the serum samples from Córdoba. Using the hemmagglutination inhibition test, we found a 98% prevalence of anti-rubella antibodies among pregnant women in Córdoba and of 96% among the women in Villa Mercedes, whereas the prevalence of anti-parvovirus 819 was 66% in the serum samples from Cordoba. These results coincide with those reported for other cities in the world, and establish an interest in continuing similar studies in order to monitor the immunization plan, which in Argentina has been going on since 1997. They also suggest the importance of the determination of IgM anti-parvovirus B19 in pregnant women who are symptomatic but with a negative result for rubella.

    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.

  2. PRELIMINARY PALEOMAGNETIC RESULTS FROM OUTFLOW EOCENE-OLIGOCENE ASH FLOW TUFFS FROM THE WESTERN MARGIN OF THE SAN LUIS BASIN: IMPLICATION FOR THE KINEMATIC EVOLUTION OF THE RIO GRANDE RIFT

    In the Rio Grande rift (RGR), a late Cenozoic continental rift from central Colorado to southern New Mexico, hanging wall margins typically contain en echelon normal fault systems with intervening areas of typically complex structure, called relay zones. Relay zones transfer displacement through complex strain patterns and eventual linkage of faults and hold clues as to how fault zones initiate and grow. The western margin of the RGR at the latitude of the San Luis basin (SLB) exposes laterally continuous Eocene-Oligocene volcanic rocks, well-correlated by 40Ar/39Ar data, and well-preserved rift structures. Ash flow tuffs are usually excellent recorders of the instantaneous geomagnetic field and five ash flow tuffs (ca. 32.3 to 27.3 Ma; including the Saguache Creek, La Jara Canyon, Masonic Park, Fish Canyon, and Carpenter Ridge tuffs) have been sampled in spatial detail along west to east transects of the eastern San Juan volcanic field to the westernmost margin of the RGR at the SLB. Data obtained from our sampling approach will yield a comprehensive definition of relative vertical-axis rotations across the area and will be used to assess the timing of RGR fault linkages. Preliminary paleomagnetic data from the Masonic Park tuff (ca. 28.2 Ma) suggest up to ~17° clockwise rotation between sample locations on the Colorado Plateau and locations to the east, nearest the western margin of the RGR. Preliminary data from the Fish Canyon tuff (ca. 27.8 Ma) show a ~12° clockwise rotation. The relative clockwise vertical-axis rotation of sampling sites in both ash flow tuffs nearest the RGR margin suggests that relay zone development with attending vertical-axis rotation played an important role in the opening of the northern RGR. Our data set is not sufficiently robust at present to test the hypothesis that rotation was taking place concurrently with eruption of these large-volume ash flow tuffs in the early Oligocene, but it is a possibility and if so, the RGR at the

    The diet and habitat landscape for fossil specimens pertaining to Late Pleistocene horse Equus sp., and mammoth Mammuthus columbi from the deposit at Rancho La Amapola, El Cedral, San Luís Potosí, México were assayed with basis on stable isotopes analysis the carbon and oxygen found in dental enamel apatite. For horses the Δ 13C values showed from C3/C4 a basic C4-plants diet ranging into a C3/C4 mixer feeder, while mammoth showed values as a C3/C4 mixer feeder, but preferring C4 plants; there was not significant differences among the average values for both groups, with -3.5 ‰ for horses and -3.8 ‰ for mammoth. Mexican data was compared with those for the same genera from US localities, including the states of Florida, New Mexico, and Texas, allowing confirmation of the inference that El Cedral species were mainly grazers, but with some C3 plants being consumed; furthermore, comparisons of El Cedral specimens, using both carbon and oxygen isotopes, with Floridan C3-plant sites showed El Cedral specimens could be defined as mixer feeders in open habitats, preferring such opn areas like grassland or savanna. Our results are in agreement with the species dental morphology, as well as with the pollen record for the same site, which showed the existence of grassland that could have extended during the Late Pleistocene from southern Canada to central Mé xico

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

    We report the results from the June 8, 2017, Ancho Canyon RF collection. While bright, electromagnetic signals were seen close to the firing point, there were no detections of signals from the explosively-fired fuse (EFF) at a collection point about 600m distant on the East Mesa. The East Mesa site was unable to collect data because the uninterruptible power supply (UPS) was exhausted by the time of the shot. We did see signals from the EFF at the Bunker 57 antennas, about 123m distant from the Point 88 firing point. The strength of these signals is consistent with our limited knowledge of the collection antenna performance and the use of the standard model to predict the electric field strength. From our knowledge of the geometry of the EFF loop and the current in the loop in this test, and from measurements at the Bunker 57 site, we predict that we would have seen signals of about 50mV at 3.67MHz in a 100 kHz channel on the Rohde & Schwarz HE010 antennas at the East Mesa location. The noise oor there is about 0.113mV (based on the March 2017 collects). Thus we would have had an SNR of 53 dB from the collect, had the data collection system been running.

    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.

    Montiel, Américo; Quiroga, Eduardo; Gerdes, Dieter

    2011-03-01

    The polychaete fauna of the Paso Ancho Basin in the Straits of Magellan was studied by means of three different sampling gears: a multibox corer, an Agassiz trawl, and a Rauschert dredge. A total of 1743 polychaete specimens belonging to 166 species from 36 families were collected at 10 stations. Significant differences were found between the catches of the three gears in terms of species numbers. The multibox corer brought up 63% of all species caught, especially macroinfauna polychaetes, the Rauschert dredge caught 16%, mostly small-bodied macroepifauna species and the Agassiz Trawl brought up 6% of the total species, largely mega-epifauna polychaetes. Only 15% of the total species occurred in more than one of the gears and only one species was found parallel in all three gears thus indicating that the combination of these gears allowed a better description of the polychaete communities than possible by just one of the gears. Using the Abundance-based Coverage Estimator and combining all species from the three different gears led to an asymptotic value of the species accumulation curve of 223 species for the Paso Ancho. Non-metric multidimensional scaling based on presence/absence data distinguished between shallow (120 m) polychaete assemblages. The shallow assemblage showed higher species richness values than the deep assemblage, and the taxonomical composition, too, differed considerably between both assemblages.

    2007-01-01

    Absolute radiocarbon datings of the sedimentary successions have come to knowledge enabling us to distinguish the Pleistocene deposits from the supra-lying Holocene ones. A palaeo-environmental evolution is proposed considering climatic fluctuations at the time, their relation with the river unloadings of the Andean glaciers and that proposed for the palaeo-lake of Salina del Bebedero. Sediments are described on the basis of a detailed field sampling, textural analysis (sieved and Bouyoucos) and laboratory geo-chemicals. Their interpretation of the geologic evolution is considered to be very important since it is the only river course on this arid-semi-arid region linked to the reduction of glaciers in the Andes. The sedimentary succession is dominated by high percentages of laminated limes and with green-yellowish to greyish-brown-reddish tones deposited in watery environments of low energy such as lacustrine basins and extended plains of flood, which is why the evolution of the deposit is characterized by the contrast of the values of insolubles (clastic sediment and carbonate) versus solubles (insoluble saline). The climatic cycles dominant and proposed for the center-east Argentine region are identified considering the influence of Andean glaciers on the river systems and the water balances in plain semi-arid environments.

    1988-01-01

    One of the major pioneer figures and outstanding personalities of particle physics, Luis Alvarez, died on 1 September. In addition to his numerous particle physics achievements, he became famous for his ventures in archaeology, palaeontology, and astronomy, and for his inventions. As a tribute to this remarkable man, we publish here some extracts from 'Adventures in Nuclear Physics', given as the 1962 University of California Faculty Research Lecture. According to custom, this presentation is a personalized account rather than an impersonal scientific discourse

    Full Text Available El estudió se realizó en la microcuenca del río Sesesmiles, Departamento de Copán, Honduras. El propósito fue explorar el efecto del ancho de franja de los bosques ribereños sobre la riqueza y abundancia de especies de aves que visitan estos bosques. Se encontraron 1 294 aves pertenecientes a 145 especies en bosques ribereños. La diversidad de aves estuvo ligada al ancho de franja de los bosques ribereños: se encontró mayor número de especies e individuos, en anchos iguales o mayores a 50 m. Las especies pertenecientes al grupo alimenticio de los insectívoros y nectarívoros fueron las más abundantes en las franjas ribereñas. Todas las especies de aves identificadas dependen de los bosques ribereños y responden al ancho del bosque; aún las especies más generalistas tienen algún grado de dependencia a las franjas ribereñas más anchas. Para conservar las poblaciones de aves en los paisajes agrícolas fragmentados es de suma importancia mantener franjas ribereñas que sean mayores a 50 m de ancho y que brinden suficientes habitas y recursos.Richness and abundance of birds in riparian forest belts of varied breadths at the Sesesmiles river microwatershed, Copan, Honduras. Riparian forests protect many species of plants and animals. We studied bird communities in riparian forest belts of the Sesesmiles river microwatershed, Copan, Honduras (140o 43’ 12" - 140o 58’ 35" N, 88o 53’ 23" - 89o 14’ 17" W. The main goal was to explore the effects of belt breadth on the richness and abundance of avian species visiting these forests. We selected 20 belts, and randomly established 30 observation points to monitor bird presence in the dry (March-April 2005 and rainy (June-July 2005 season (N= 60 observations. A total of 1 294 birds belonging to 145 species were recorded. Bird diversity was significantly correlated to the breadth of the riparian belts, with a greater number of species and individuals in belts 50 m wide or wider

  17. Linking selenium sources to ecosystems: San Francisco Bay-Delta Model

    Science.gov (United States)

    Presser, Theresa S.; Luoma, Samuel N.

    2004-01-01

    Marine sedimentary rocks of the Coast Ranges contribute selenium to soil, surface water, and ground water in the western San Joaquin Valley, California. Irrigation funnels selenium into a network of subsurface drains and canals. Proposals to build a master drain (i.e., San Luis Drain) to discharge into the San Francisco Bay-Delta Estuary remain as controversial today as they were in the 1950s, when drainage outside the San Joaquin Valley was first considered. An existing 85-mile portion of the San Luis Drain was closed in 1986 after fish mortality and deformities in ducks, grebes and coots were discovered at Kesterson National Wildlife Refuge, the temporary terminus of the drain. A 28-mile portion of the drain now conveys drainage from 100,000 acres into the San Joaquin River and eventually into the Bay-Delta. If the San Luis Drain is extended directly to the Bay-Delta, as is now being proposed as an alternative to sustain agriculture, it could receive drainage from an estimated one-million acres of farmland affected by rising water tables and increasing salinity. In addition to agricultural sources, oil refineries also discharge selenium to the Bay-Delta, although those discharges have declined in recent years. To understand the effects of changing selenium inputs, scientists have developed the Bay-Delta Selenium Model.

    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

    Full Text Available Changes in nutrients, chlorophyll and zooplankton were followed for 11 d in a basin of the Straits of Magellan (Paso Ancho, characterized by a homogeneous water column during a spring event defined by a drastic change in wind stress and direction. Conditions hardly seemed conducive to a phytoplankton bloom. Initial conditions were characterized by SW gales, low nutrients as well as by Chaetoceros spp. and Thalassiosira spp. dominated phytoplankton. Wind switched abruptly to calm-weak northerlies by the middle of the study period, a subsurface chlorophyll peak developed and extended to the end of the study while nitrates decreased. Zooplankton was dominated by copepods, nauplii and a diverse meroplankton assemblage. Zooplankton composition was rather uniform, except for diel changes in some taxa. Gut contents of zooplankton size fractions (including Euphausia vallentini as the largest fraction were measured. Grazing rates accounted for 0.5 % of the available chlorophyll. Phytoplankton blooming may be explained by transient water stratification resulting from the relaxation of wind stress and eventual retention of the phytoplankton in the photic layer. Minor variability in zooplankton implied the existence of a permanent and distinct assemblage in a strongly homogeneous environment.

  10. Miocene and Pleistocene mollusks from San Andres Island (Caribbean Sea, Colombia) and Paleogeographic considerations

    International Nuclear Information System (INIS)

    Diaz M, Juan Manuel; Garcia Llano, Cesar Fernando

    2010-01-01

    San Andres Island is the largest emerged portion of the oceanic archipelago of San Andres and Providencia, southwestern Caribbean Sea; it originated as a coralline atoll during Miocene times. The central and highest part of the island consists of a calcareous crest, the San Andres Formation, formed by Neogene lagoonal and reefal deposits. This crest is surrounded by a calcareous platform of Pleistocene age (San Luis Formation) which emerges only along the island coast, whereas its most part is submerged and covered by a Recent reef complex. Fossil material of molluscs from these two formations was collected in various sites throughout the island and taxonomically identified. In the four sites sampled in the San Andres Formation, material belonging to 19 gastropod and 37 bivalve species was obtained, most of them relatively well represented in other geologic formations of the Caribbean region that are stratigraphically situated between the upper Miocene and the middle Pliocene. Some elements occurring in this formation, such as Ostrea haitiensis, Meretrix dariena and Siphocypraea henekeni, were widely distributed in the Caribbean Miocene Province. In the San Luis Formation, material belonging to 18 gastropod and 11 bivalve species was obtained, most of them also represented in the Recent molluscan fauna of the region. The estimated age of this formation is Sangamonian, hence corresponding to similar formations occurring in Grand Cayman, Jamaica, Hispaniola, the Netherlands Antilles and other Caribbean islands, with which it also shows a great similarity in the composition of the molluscan fauna.

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.

    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.

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

    Groundwater is scarce in arid and semi-arid zones in the Mexican Mesa Central. It is found at depths over 200 m, and its movement is primarily through fractures. This work aims to present a geophysical methodology, which shows the potential of combining natural and induced methods to locate confined aquifers in fault zones. The studies begin by interpreting the aeromagnetic survey, mainly by seeking lineaments associated with low magnetic anomalies, which are correlated with fault zones, and/or fractures and/or geological contacts where ferromagnetic minerals have undergone oxidation due to their association with recharge zones. These aeromagnetic lineaments are confirmed on land by a ground magnetic survey. After locating these areas, interpreted as permeability zones, their possible association with moist zones is confirmed by applying the vertical electrical sounding (VES) technique. H-type curve is associated with the presence of saturated zones. This study used the proposed methodology to interpret four main aeromagnetic lineaments and 12 main ground magnetic lineaments in a 36 km2 (6 km × 6 km) area. Twenty-six SEV were performed over these magnetic lineaments, of which about 50 % were associated with H-type resistivity curves, interpreted as being associated with moisture. Of the 12 VES with inferred groundwater potential, two wells have been drilled to date, one having an extraction flow of 70 lps.

    1984-10-01

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H 2 O/D 2 O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    Full Text Available We analyzed the composition, diversity, and abundance of marine fish at rocky reefs off San José island, Mexico between October 2001 and August 2002. Fish species were recorded using a visual census in 5 sampling areas of 50 by 5 meters at 2 depths, shallow (1-3 meters and intermediate (5-7 meters. A total of 26 946 organisms were counted, belonging to 84 species. The families Serranidae (9 species, Labridae (8, Pomacentridae (7, and Haemulidae (6 were the most representative. We measured the rugosity of the bottom surface, which showed a positive relationship with abundance, richness, and fish diversity. The ocean bottom off San José island is covered with various size rocks that offer more feeding and refuge areas to fish assemblages than other areas. The ecological index increased during the warm season. Diversity and richness showed significant variations (PSe analizó la estructura íctica de los arrecifes rocosos de Isla San José, México entre octubre del 2001 y agosto del 2002.

    1998-01-01

    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.

A series of added chapters have extended the detailed analysis to the Fray Luis versions, using even that to remake a botanical vocabulary and to study a Quevedo’s religious sonnet and the «No me mueve mi Dios para quererte» («My God doesn’t move me to love you». All this philological baggage, hard to enumerate as a summary, constantly goes back to ecdotic tasks that allow the solving of (or to present textual problems.

    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

    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.

En este artículo se estudian dichas referencias y se concluye que realmente no hay una relevancia epistémica de este paso en relación con el galenismo y que la historiografía de Mercado sobre este tránsito pulmonar de la sangre debe ser revisado con detenimiento, pues nunca rechazó categóricamente este paso de la sangre.

    Full Text Available The architectural restoration carried out in Spain during half of the 20th century is characterised by the work of a small group of architects who were exclusively responsible for the refurbishment of the built heritage. One of the most outstanding among them was Luis Menéndez Pidal, whose work is a compendium of the evolution of restoration philosophies in Spain during the fifty central years of the last century. This article provides an interesting overview of this architect, from his education to his thinking, illustrated by his major interventions on Spanish architectural heritage.

  7. On editing the fifth stanza of El aire se serena by fray Luis

    Full Text Available Although many scholars and editors of the ode «El aire se serena» by fray Luis de León have denied or questioned the authenticity of its fifth stanza, there now seems to be a general assent to its acceptance. The reason for such a change of heart has not to do with textual criticism proper, but with literature. The sources of the ode are said to justify it. In this paper a strictly critico-textual demonstration of the authenticity of stanza 5 is proposed, placing emphasis on the cause of the diffraction displayed in the erroneous lectiones of a segment of the stanza.

    1988-01-01

    Livers of gopher snakes (Pituophis melanoleucus) from Kesterson Reservoir (Merced County, California) contained significantly higher mean selenium concentrations (11.1 .mu.g/g, dry weight) than those from two nearby reference sites (2.05 and 2.14 .mu.g/g). Livers of bullfrogs (Rana catesbeiana) collected from the San Luis Drain at Kersterson Reservoir also contained significantly higher mean selenium concentrations (45.0 .mu.g/g) than those from nearby reference sites (6.22 .mu.g/g). The high levels of selenium bioaccumulation in these snakes and frogs at Kersterson Reservoir reflected the elevated levels found in their food organisms. We did not examine that snakes or frogs from Kesterson for signs of ill health, but the concentrations we found were sufficiently high to warrant concern about potential adverse effects in these animals and their predators.

    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.

  17. Continuity of the San Andreas Fault at San Gorgonio Pass

    Carena, S.; Suppe, J.

    2002-12-01

    The San Andreas fault at San Gorgonio Pass does not have a clear surface trace and is considered aseismic. Our findings suggest in fact that the existence of a through-going vertical or near-vertical San Andreas fault between Yucaipa and North Palm Springs is highly unlikely. We mapped over 70 faults in the San Gorgonio Pass-San Bernardino Mountains region using the catalog of 43,500 relocated 1975-1998 earthquakes of Richards-Dinger and Shearer (2000). A clustering algorithm was applied to the relocated earthquakes in order to obtain tighter earthquake clouds and thus better-defined fault surfaces. The earthquakes were then imported into Gocad, a 3D modeling software that allowed us to separate earthquakes into coplanar clusters associated with different faults and fault strands and to fit optimized surfaces to them. We also used the catalog of 13,000 focal mechanisms of Hauksson (2000) to confirm the nature of the mapped faults. We were able to constrain the 3D geometry of the San Andreas fault near San Gorgonio Pass from the 3D geometry of the fault network surrounding it. None of these faults show any displacement due to an hypothetical sub-vertical San Andreas. The San Andreas fault must therefore rotate to much shallower dips, or lose its continuity at depths between 3 and 15 km The most likely configuration is the one where the San Andreas fault merges into the shallow-dipping San Gorgonio Pass thrust W of North Palm Springs. Strike-slip motion is taken up by both the thrust (the slip vector on the N. Palm Springs segment is reverse/right-lateral strike-slip) and by a series of NW striking faults in the footwall of the thrust. The W termination of the most active part of the San Gorgonio Pass thrust coincides with one of these footwall faults at depth, and with the south bend in the San Andreas fault strand N of Banning. This boundary also marks a change in the stress field, with a dominant strike-slip regime to the E (and localized thrusting between San

    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.

However, Patiño-Camargo performed other investigations from 1917-1943, which represent the first descriptions and scientific evidence of the presence of R. prowazekii and R. typhi in Colombia. Almost 60 years after the latest research conducted by Dr. Patiño-Camargo, rickettsioses were again a matter of interest and research. In the last decade over 20 research studies have been published, showing new endemic areas for R. rickettsii, as well as the description of new rickettsial species in Colombia. PMID:27074327

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

    Satellite laser ranging techniques are used to monitor the broad motion of the tectonic plates comprising the San Andreas Fault System. The San Andreas Fault Experiment, (SAFE), has progressed through the upgrades made to laser system hardware and an improvement in the modeling capabilities of the spaceborne laser targets. Of special note is the launch of the Laser Geodynamic Satellite, LAGEOS spacecraft, NASA's only completely dedicated laser satellite in 1976. The results of plate motion projected into this 896 km measured line over the past eleven years are summarized and intercompared.

    The first planning studies that gave rise to the San Bernabe substation go back to year 1985. The main circumstance that supports this decision is the gradual restriction for electric power generation that has been suffering the Miguel Aleman Hydro System, until its complete disappearance, to give priority to the potable water supply through the Cutzamala pumping system, that feeds in an important way Mexico City and the State of Mexico. In this document the author describes the construction project of the San Bernabe Substation; mention is made of the technological experiences obtained during the construction and its geographical location is shown, as well as the one line diagram of the same [Espanol] Los primeros estudios de planeacion que dieron origen a la subestacion San Bernabe se remontan al ano de 1985.

    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.

    2005-04-01

    Full Text Available In the precarious economic conditions prevailing after the Spanish Civil War, tiled vault construction was resumed to economize on steel and capitalize on the cheap labour available at the time.
    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.

    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

    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.

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

  10. ASTER Flyby of San Francisco

    Science.gov (United States)

    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 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.

  18. Impact of Hurricane Luis on the health services of Antigua and Barbuda.

    Science.gov (United States)

    Gibbs, T; van Alphen, D

    1996-01-01

    Antigua and Barbuda, located in the Caribbean, was one of the countries most affected by Hurricane Luis in 1995. Electricity, water supply and health facilities were disrupted for several weeks. Inadequate criteria at the design stages, unsound structural design, and lack of maintenance of building components, are some of the reasons that damage was so severe. The main hospitals and 6 health facilities were destroyed and flooded and most of the medical staff had to cope with their own damaged houses. Although the knowledge and materials are available to reduce the losses caused by hurricanes, building codes are not reinforced by laws and preventive maintenance to protect health care facilities from natural hazard damage is not usually budgeted for. The additional cost of making a single or two-storey health facility almost invulnerable to future catastrophe in a hurricane is only 2% in initial capital cost and becomes negligible when spread over the life of a building. The effort of UN International Decade for Natural Disasters (IDNDR) directed towards disaster mitigation should be increased over the remainder of the decade to ensure that standards are respected and building codes are mandatory.

  19. The pastoral implications of human freedom according to Juan Luis Segundo

    Directory of Open Access Journals (Sweden)

    Vicente de Paula Ferreira

    2016-09-01

    Full Text Available The paper aims to reflect the issue of human freedom based on the underlying principles of the Christian faith in a time of anthropological vulnerability, especially in Latin American. It holds that Christianity must insist on its proposal to promote universal goodwill, despite a human horizon marked by selfishness and lust for power and money. This approach presupposes a radical position of a listener of the divine mystery, revealed in Jesus Christ, as a way to fulfill the human condition. Theoretical framework: Liberation Theology, in the view of Juan Luis Segundo, and its well-established tradition of transforming realities of injustice through faith, comprises the core argument of this text. Findings: Christian salvation necessarily implies the kenosis (κένωσις of Jesus, i.e., Christ “emptied Himself” (Ph. 2:7, and through His humble dispossession, He broke with all closed systems of the world, and inaugurated a new venture of a liberated freedom: the agape of love. Conclusion: Christian praxis as daily care for the poorest and prophecy of forgiveness rescues the memory of the victims of all forms of human selfishness.

    Imelda Rodríguez-Escanciano, Ph.D.

    2010-01-01

    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.

  2. Syntactically Silent Subjects: Luis Muñoz and the Poetry of Ellipsis

    Directory of Open Access Journals (Sweden)

    Judith Nantell

    2012-06-01

    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 El artículo aborda la producción cuentística de Luis Fayad entre Los sonidos del fuego (1968 y Un espejo después y otros relatos (1995 con el objeto de percibir tanto las variaciones de Bogotá, como las mediaciones estéticas a través de las cuales se representan literariamente los conflictos urbanos, políticos y sociales de la capital colombiana entre la década de los sesenta y la de los noventa del siglo XX. El narrador bogotano se sitúa en los intersticios de las problemáticas de su ciudad para descubrir aristas desconocidas de un proceso que no siempre es evidente en los estudios sociológicos o antropológicos; de esta manera los relatos inscriben las transformaciones del espacio citadino desde que deja de ser una aldea grande hasta que se convierte en una urbe masificada, visibilizando restos de memorias colectivas, conflictos existenciales y sociales, marginamientos y pequeñas historias de vida, hasta constituir un entramado discursivo que permite leer signos y rostros de una ciudad en proceso de metamorfosis permanente.

    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

    Radon and gamma radiation level measurements were carried out inside the La Carolina mine, one of the oldest gold mining camps of southern South America, which is open for touristic visits nowadays. CR-39 track-etch detectors and thermoluminescent dosimeters of natural CaF{sub 2} and LiF TLD-100 were exposed at 14 points along the mine tunnels in order to estimate the mean {sup 222}Rn concentration and the ambient dose equivalent during the summer season (November 2008 to February 2009). The values for the {sup 222}Rn concentration at each monitoring site ranged from 1.8 +- 0.1 kBq m{sup -3} to 6.0 +- 0.5 kBq m{sup -3}, with a mean value of 4.8 kBq m{sup -3}, indicating that these measurements exceed in about three times the upper action level recommended by ICRP for workplaces. The correlations between radon and gamma radiation levels inside the mine were also investigated. Effective doses due to {sup 222}Rn and gamma rays inside the mine were determined, resulting in negligible values to tourists. Considering the effective dose to the mine tourist guides, values exceeding 20 mSv of internal contribution to the effective doses can be reached, depending on the number of working hours inside the mine.

    Cardiometabolic risk factors, including hypertension, dyslipidemia, central obesity, insulin resistance and diabetes are linked to cognitive impairment. The Hispanic population appears to be differentially affected by both cardiometabolic risk factors and cognitive impairment. We sought to determine whether ethnic differences in cognitive impairment in long-resident southwestern US elders was explained by the presence of cardiometabolic risk factors, and to explore patterns of cognitive decline over time. We performed a secondary analysis of data collected on 378 Hispanic and 409 non-Hispanic white adult participants in a longitudinal study of community-dwelling elderly in southern Colorado. Measures of cardiometabolic risk included waist circumference, blood pressure, diagnosis of diabetes, and random blood glucose. Cognitive measures included the Mini-Mental State Exam (MMSE) and the behavioral dyscontrol scale (a measure of executive cognitive function), at baseline and after an average of 22 months. Subjects were also administered the Center for Epidemiologic Studies Depression Scale, and the Coronary Artery Risk Development in Young Adults 1-Year Activity Recall. At baseline, Hispanic elders had a greater number of cardiometabolic risk factors and lower MMSE and behavioral dyscontrol scale scores than non-Hispanic whites. Hispanic ethnicity was associated with a greater likelihood of decline in general cognitive function, but not executive cognitive function, after adjusting for age and education. This differential decline was not explained by either individual or total number of baseline cardiometabolic risk factors, depression, or physical activity. A borderline increased risk of decline in general cognitive function was seen in sedentary individuals (P = 0.05).

    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.

    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.

    This essay employs the concepts of “the haunted place” (Michel de Certeau and “the sense of place” (Kent Ryden to examine the representation of the US-Mexico border in the works of Federico Campbell, Luis Humberto Crosthwaite, Francisco Morales and Heriberto Yépez. While Campbell, Crosthwaite, and Morales represent Tijuana as a place imbued with personal and collective history, Yépez, in his most recent novel, Al otro lado, offers an apocalyptic vision of this border city, defined by narcoviolence, illegal immigration, and militarization.

    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.

    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

  14. Application of Cs-137 techniques to problems of sediment redistribution in Sungai Lui representative basin, Selangor, Malaysia (Part 1)

    1982-11-01

    Since the beginning of the nuclear age, Cesium-137 has become a part of the world's ecosystems. Cs-137 is carried from the atmosphere to the ground by rainfall. On reaching the earth's surface, 137 Cs becomes strongly adsorbed to soil profiles and is concentrated predominantly in the surface layer, particularly in clayey soils. Systematic measurements of Cs-137 levels will therefore permit estimates to be made of the cumulative effects of soil redistribution over the past 25 years. Sediment movement in river catchments and coastal areas is a very old problem in Malaysia. In view of rapid development of urban and agricultural areas in Malaysia it was realised tha soil loss problems are particularly serious. The Sungai Lui catchment was chosen to be the investigational site. Geologically, the area comprises of granite and granitic schist. The area is mostly covered by forest (approx. 83%) and rubber (13%), padi (2%) and others (2%). The climate is considered to be typical of Peninsular Malaysia (equatorial) characterised by uniform temperature, high humidity and high rainfall. The area is mainly drained by the Lui River. Soil samples were collected from the catchment area at 4 sampling points in April 1981. The results of analyses of Cs-137 in soil samples from Sungai Lui catchment area ranged from 1.3 to 6.8 M Bq g -1 of sample and they could still be detected even up to 20 cm depth. A general pattern of Cs-137 distribution was observed in the soil profile at each site. The highest activity being in the top 3 cm layer and then decreasing up to about 6 cm. The activity increases again up to about 9 cm layer. From there onwards, it decreases. Based on these results, the estimated rate of sediment accumulation in the area was found to be about 0.47 cm/year. Since the samples were only collected from the depositional sites, further sampling especially from erosional site should therefore be carried out in order to obtain more complete data

    The prominent linear feature straight down the center of this perspective view is California's famous San Andreas Fault. The image, created with data from NASA's Shuttle Radar Topography Mission (SRTM), will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, Calif., about 100 kilometers (about 60 miles) northwest of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. Another fault, the Garlock Fault lies at the base of the Tehachapis; the San Andreas and the Garlock Faults meet in the center distance near the town of Gorman. In the distance, over the Tehachapi Mountains is California's Central Valley. Along the foothills in the right hand part of the image is the Antelope Valley, including the Antelope Valley California Poppy Reserve. The data used to create this image were acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour

  10. Alfonso Luis Herrera and the Beginnings of Evolutionism and Studies in the Origin of Life in Mexico.

    Ledesma-Mateos, Ismael; Cleaves, H James

    2016-12-01

    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.

    2015-01-01

    Full Text Available Il presente articolo si propone di tracciare il ritratto di uno dei grandi maestri di studi ispanoamericanistici, Giuseppe Bellini, attraverso una recente opera miscellanea a lui dedicata, a cura di Patrizia Spinato Bruschi e Jaime Martínez. 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.

Scopo di questo studio è quello di analizzare le caratteristiche e le problematiche legate alla “questione amorosa” di doña Clara e don Luis, il modo in cui nasce e si sviluppa tale intreccio e le tecniche narrative attraverso cui Cervantes ricollega e amalgama questa storia d’amore a quelle delle altre coppie presenti nella conclusione della Primera Parte del Quijote.ENDoña Clara and don Luis are the last couple of lovers arriving to Palomeque's inn. They are the umpteenth romantic couple in a string of episodes based on several recognition scenes between different couples.  That's why they contribute to reach that "scandalous happy end" – as Juan Benet ironically defined it –, through which the main action of the novel's plot comes to a conclusion and allows to finish, at the same time, all the secondary plots at the inn. This report aims to analyze the characteristics and problems related to "the love issue" between Doña Clara and don Luis and, in special, all the particular narrative techniques which Cervantes uses to link this "love story" with other couples in the first part of Don Quijote.Keywords: Cervantes – Don Quijote – narrative techniques – Doña Clara and Don Luis – love question

In order to go in depth into the ethical dimension of Karl Marx's and the marxist tradition's thought, the text proposes several thematic lines of analysis with the aim of liberating, at the same time, the intelectual and political project of Marx from the various clichés associated to its traditional reception. The ethical field will appear as a space of mediation between knowledge and reality, disclosing itself as fundamental to marxism from a praxeological point of view. At the end of the article there is a critical dialogue with different ethical positions in the frame of contemporary marxism.A partir de una lectura crítica de El marxismo como moral, obra clásica de José Luis López Aranguren, éste artículo trata de interrogarse acerca de los fundamentos normativos y morales del marxismo.

    Full Text Available The feeding of Engraulis anchoita was studied in the coastal reproductive habitat of the northern population during the spawning period. Stomach contents of anchovy adults and plankton samples taken during a research cruise were examined. The highest stomach fullness values were found in the Rio de la Plata estuary, particularly at stations close to the surface salinity front. Copepods, particularly those 1 mm total length. This might be explained by a low gill rakers efficiency of adult anchovies to retain small prey. In the Rio de la Plata front, both the reported large biomasses of zooplankton and the observed intense anchovy feeding revealed the ecological significance of this front, especially when compared with the contiguous "poor in food" coastal areas.Se estudió la alimentación de la población norteña de Engraulis anchoita en el hábitat reproductivo costero durante su periodo de desove. Se analizaron los contenidos estomacales de adultos de anchoíta y muestras de zooplancton tomados durante un crucero de investigación. Los mayores valores de repleción estomacal se encontraron en el estuario del Río de la Plata, particularmente en estaciones cercanas al frente salino de superficie. Los copépodos fueron las presas más abundantes, particularmente especímenes 1 mm de longitud total. Esto se puede explicar por la baja eficiencia del aparato branquial de anchoítas adultas para retener pequeñas presas. En el frente del Río de la Plata, las altas biomasas de zooplancton reportadas y la intensa alimentación observada, evidencian su significancia ecológica, especialmente cuando se compara con aguas costeras adyacentes pobres en alimento.

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

    Science.gov (United States)

    Hudnut, K. W.

    2013-12-01

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

    2017-05-02

    We report a microfluidic approach to perform small angle neutron scattering (SANS) measurements of contrast variation and matching, extensively employed in soft and biological matter research. We integrate a low scattering background microfluidic mixer and serpentine channel in a SANS beamline to yield a single phase, continuous flow, reconfigurable liquid cell. By contrast with conventional, sequential measurements of discrete (typically 4-6) solutions of varying isotopic solvent composition, our approach continually varies solution composition during SANS acquisition. We experimentally and computationally determine the effects of flow dispersion and neutron beam overillumination of microchannels in terms of the composition resolution and precision. The approach is demonstrated with model systems: H 2 O/D 2 O mixtures, a surfactant (sodium dodecyl sulfate, SDS), a triblock copolymer (pluronic F127), and silica nanoparticles (Ludox) in isotopic aqueous mixtures. The system is able to zoom into a composition window to refine contrast matching conditions, and robustly resolve solute structure and form factors by simultaneous fitting of scattering data with continuously varying contrast. We conclude by benchmarking our microflow-SANS with the discrete approach, in terms of volume required, composition resolution and (preparation and measurement) time required, proposing a leap forward in equilibrium, liquid solution phase mapping and contrast variation by SANS.

  6. Evidence from precise earthquake hypocenters for segmentation of the San Andreas Fault in San Gorgonio Pass

    Science.gov (United States)

    Magistrale, Harold; Sanders, Christopher

    1996-02-01

    We use precise hypocenter patterns and focal mechanisms to investigate the presence or absence of a continuous strike-slip fault at depth connecting the San Bernardino strand of the San Andreas fault with the Coachella Valley segment of the Banning fault. We inverted 560,000 arrival times from 23,000 earthquakes (1981-1993) for high-quality hypocenters and three-dimensional P wave velocity structure in a 1° by 2° area centered on the San Gorgonio Pass. Cross-sectional plots of relocated earthquakes reveal an abrupt 5 to 7 km high step in the maximum depth of hypocenters. The step riser defines a near-vertical, locally curved surface that extends westerly more than 60 km from the Coachella Valley segment of the San Andreas fault to the San Jacinto fault. A hypothetical continuous vertical San Andreas fault through San Gorgonio Pass would cross the step at an oblique angle. We suggest that the step is the expression of the contact between different basement rock types juxtaposed by large-scale right-slip motion on the ancestral San Andreas fault. South of the step in Peninsular Ranges type basement (intrusives), brittle failure occurs down to about 20-km depth, while north of the step in San Bernardino type basement (Pelona schist), brittle failure occurs to only about 13-km depth. The step provides a piercing plane that should be offset about 3 km right laterally by an active, continuous, vertical San Andreas fault. Within the resolution of our mapping the step is not offset in this manner, implying either that there has not been a throughgoing vertical fault at depth, that a throughgoing fault has not experienced enough slip to offset the step, or that a throughgoing fault is not vertical and dips north over the top of the step. Hypocentral patterns and focal mechanisms indicate distributed deformation (thrust, normal, and strike-slip faulting) over a large volume in the San Gorgonio Pass region; there is no evidence of hypocenter or slip vector alignments that

    the 2003 damage was caused by lateral spreading in two separate areas, one near Norswing Drive and the other near Juanita Avenue. The areas coincided with areas with the highest liquefaction potential found in Oceano. Areas with site amplification conditions similar to those in Oceano are particularly vulnerable to earthquakes. Site amplification may cause shaking from distant earthquakes, which normally would not cause damage, to increase locally to damaging levels. The vulnerability in Oceano is compounded by the widespread distribution of highly liquefiable soils that will reliquefy when ground shaking is amplified as it was during the San Simeon earthquake. The experience in Oceano can be expected to repeat because the region has many active faults capable of generating large earthquakes. In addition, liquefaction and lateral spreading will be more extensive for moderate-size earthquakes that are closer to Oceano than was the 2003 San Simeon earthquake. Site amplification and liquefaction can be mitigated. Shaking is typically mitigated in California by adopting and enforcing up-to-date building codes. Although not a guarantee of safety, application of these codes ensures that the best practice is used in construction. Building codes, however, do not always require the upgrading of older structures to new code requirements. Consequently, many older structures may not be as resistant to earthquake shaking as new ones. For older structures, retrofitting is required to bring them up to code. Seismic provisions in codes also generally do not apply to nonstructural elements such as drywall, heating systems, and shelving. Frequently, nonstructural damage dominates the earthquake loss. Mitigation of potential liquefaction in Oceano presently is voluntary for existing buildings, but required by San Luis Obispo County for new construction. Multiple mitigation procedures are available to individual property owners. These procedures typically involve either

    Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

It is a very high number compared to what Europeans frontline composers have produced during the twentieth century and the first decade of the 21st. From all this great production, surely excel his operas, as three of his five works dedicated to this genre, the saxophone is present and also with dramatic character roles. Then we will make an analysis of the opera La señorita Cristina, and the employment of the saxophone there, with musical contributions that eleven years after its release are certainly innovative and interesting.A sus 82 años no vamos a citar la importancia e influencia de Luis de Pablo en la historia musical de España en los últimos cincuenta años, pero no fue esto lo que me llamó la atención para realizar una tesis doctoral sobre su música1, sino la gran producción de obras con saxofón dentro de su catálogo: veinticinco obras al momento de hoy. Es un número muy alto comparándolo con lo que los compositores europeos de primera línea han llevado a cabo durante el siglo XX y primera década del XXI. De toda esta gran producción, destacan sin duda sus óperas, ya que en tres de sus cinco obras de este apartado, el saxofón está presente y además con funciones de personaje dramático. A continuación vamos a efectuar un análisis de la ópera La señorita Cristina y del empleo del saxofón en la misma, con unas aportaciones musicales que once años después de su estreno son sin duda novedosas y muy interesantes.

    A series of restructured clays used as catalysts in small- and large-scale chemical reactions, have been studied by small-angle neutron scattering (SANS). Analysis of the spectra provides detailed information both on the nanopore structure and the surface texture of these materials. Additionally, pillared inter-layered clays (PILCs) have a great potential for industrial utilisation in catalysis, sorption and separations. PILCs have been studied with contrast-matching SANS in order to independently resolve the structure of each phase since by matching the neutron scattering length density of the clay or the pillars, the scattering curve results only from the non-contrast matched phase

    1982-06-01

    Construction and operation of large-scale wind-turbine fields on approximately 12,780 acres of public land in the San Gorgonio Pass of Palm Springs, California are proposed. The wind farm systems would be operated by Windfarms Limited, U.S. Windpower, Southern California Edison Company, PanAero Corporation, the city of Riverside, and San Gorgonio Farms, Inc. Implementation of the preferred scheme would allow development of wind turbines on public lands except in those areas that have been identified as having resources that are extremely sensitive to development. Positive and negative impacts of the project are discussed.

    1995-11-01

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

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

  11. Determining the physical and chemical processes behind four caldera-forming eruptions in rapid succession in the San Juan caldera cluster, Colorado, USA

    A primary goal of volcanology is to understand the frequency and magnitude of large, explosive volcanic eruptions to mitigate their impact on society. Recent studies show that the average magma flux and the time between magma injections into a given magmatic-volcanic system fundamentally control the frequency and magnitude of volcanic eruptions, yet these parameters are unknown for many volcanic regions on Earth. We focus on major and trace element chemistry of individual phases and whole-rock samples, initial zircon ID-TIMS analyses, and zircon SIMS oxygen isotope analyses of four caldera-forming ignimbrites from the San Juan caldera cluster in the Southern Rocky Mountain volcanic field, Colorado, to determine the physical and chemical processes leading to large eruptions. We collected outflow samples along stratigraphy of the three caldera-forming ignimbrites of the San Luis caldera complex: the Rat Creek Tuff ( 150 km3), Cebolla Creek Tuff ( 250 km3), and Nelson Mountain Tuff (>500 km3); and we collected samples of both outflow and intracaldera facies of the Snowshoe Mountain Tuff (>500 km3), which formed the Creede caldera. Single-crystal sanidine 40Ar/39Ar ages show that these large eruptions occurred in rapid succession between 26.91 ± 0.02 Ma (Rat Creek Tuff) and 26.87 ± 0.02 Ma (Snowshoe Mountain Tuff), providing an opportunity to investigate the temporal evolution of magmatic systems feeding large, explosive volcanic eruptions. Major and trace element analyses show that the first and last eruption of the San Luis caldera complex (Rat Creek Tuff and Nelson Mountain Tuff) are rhyolitic to dacitic ignimbrites, whereas the Cebolla Creek Tuff and Snowshoe Mountain Tuff are crystal-rich, dacitic ignimbrites. Trace elements show enrichment in light rare-earth elements (LREEs) over heavy rare-earth elements (HREEs), and whereas the trace element patterns are similar for each caldera cycle, trace element values for each ignimbrite show variability in HREE

À première vue, Haïti demeure le même ; c’est le statu quo que le narrateur observe : l’odeur du café est la même, la pauvreté aussi crue que violente affecte la population, les amis du narrateur sont restés fidèles à leur jeunesse. Par la même occasion, le roman relance le débat sur la pertinence de la migration, qui, du coup, semble moins centrée à une ère où l’imaginaire se situe au-delà des pays « réel » et « imaginaire » ; cette dichotomie donne une vraie valeur intrinsèque à Pays sans chapeau et démontre, de ce fait, la belle forme technique et esthétique du roman.

Pays sans chapeau (a country without hat is one of the novels written by Dany Laferrière and published in 2007. This book deals with the return of the narrator, Vieux Os, to Port-au-Prince after many decades spent abroad in exile. It is also based on the painting or description of the Haitian society in which the narrator is horrified by the sheer number of the dead people or ghosts walking around together with the living in the streets of the city. He realises that the city of Port-au-Prince is overcrowded, yet he cannot distinguish the living from the dead amongst the bodies. The article aims to research the perpetual problem of the relationship between reality and fiction in autobiographical texts. An attempt will be made to determine to which category the novel Pays sans chapeau belongs. Consequently, it also analyses the dichotomy between the

    Full Text Available La obra literaria creada en el destierro por los españoles tuvo ciertos caracteres esenciales que le llevan a formar parte de una tendencia distinta, a no ligarse a los movimientos literarios coetáneos que se manifestaban en la península. La lírica fue el género más influenciado por la situación que los exiliados estaban experimentando, razón por la que sus textos pueden dividirse en periodos, con diferentes rasgos, dependientes de la situación histórica que experimentaban: Segunda Guerra Mundial, final de la guerra y afianzamiento del Franquismo, etc. Entre los muchos autores exiliados, Luis Cernuda fue uno de los más reconocidos, donde los rasgos de la poética del destierro estaban presentes, de una forma velada, trágica y sucinta, como era propio de toda su producción.

    Full Text Available El objetivo del artículo es presentar la vida y trayectoria del empresario agrícola Luis García Pimentel, reconocido representante de la elite regional porfiriana de Morelos, propietario de dos haciendas azucareras ubicadas al oriente de la entidad, la de Santa Ana Tenango y la de Santa Clara Montefalco. El personaje se estudió desde el ámbito de la historia económica, mediante una escrupulosa investigación en siete archivos, y en bibliografía concerniente y actualizada del tema. Cabe destacar que no existen estudios similares de empresarios porfiristas de Morelos y la importancia de documentos encontrados en el Archivo de Notarias de la Ciudad de México que aportan información relevante y desconocida en fuentes secundarias. La monografía muestra cómo antes de la revolución, García Pimentel se desempeñaba exitosamente en los negocios, conocía su entorno y lo aprovechaba para aumentar sus ganancias. Tras la lucha armada, sin embargo, no pudo recuperar el auge económico anterior.

    Full Text Available The majority of fictional texts can be localized geographically in terms of scenarioand plot. However, these localizations are constructed in different ways, fromimaginary to realistic. I will analyze the contemporary novelDesterro: memórias emruínas(2011, byLuisS. Krausz, following this premise. The book offers a range ofsophisticated representations of fictionalized real spaces, some of themrepresenting a past that no longer exists.Through my analysis I will test a specialmethod that has beendeveloped recently under the name of “literary geography”.This approach addresses the relevant questions of text-space relations in general,as well as the different forms of referring to geographical spaces (indicating,suppressing, anonymizing, transforming. Furthermore, different functions areattributed to the fictionalized spaces. In a second step, in line with the samemethod, I will test the potential of maps in providing an interpretative frameworkfor the analysis. Possible limitations to this method will then be discussed.

    Full Text Available La edición de Cátedra de La guaracha del Macho Camacho (2000 de Luis R. Sánchez lleva en su portada una reproducción incompleta de un llamativo cartel del artista puertorriqueño José Rosa. Esta obra, un iconotexto que estudiamos y reproducimos íntegramente, incorpora una rica serie de citas –falsas y verdaderas– de La guaracha. Proponemos un recorrido interpretativo de la configuración visual y textual de esta imagen, creada con otro fin que el de servir de pórtico a la novela. Con ella Rosa condensaba ya en 1977 de manera sorprendente muchos de los enfoques que los críticos literarios de Sánchez sólo desarrollarían mucho más tarde: la desacralización, el enmascaramiento racial, sexual y social, la dictadura del ocio y del consumo, el barroquismo... Como copista infiel y retozón, Rosa reinterpreta La guaracha insertando su autobiografía en ella y sobre todo insistiendo en que oigamos su trasfondo sonoro más profundo hecho de violencia, de racismo, de explotación y de exclusión.

    Full Text Available One of the most important consequences of Portuguese discoveries was the black slavery business. A most reputed theologist and jurist of the time, Juan de Molina, who had a first-hand knowledge of the subject, made a thorough analysis of the justness of slavery from a Theology and Law perspective, while showing himself opposed to the same. His doctrine set basis for future thought and he must be considered as the first great tratadist on black slavery.

    Una de las consecuencias más importantes de los descubrimientos portugueses en África fue el negocio de los esclavos negros. Luis de Molina, uno de los teólogos y juristas más importantes de su época y con un gran conocimiento del asunto, trató el tema de la licitud de los esclavos negros en amplitud, analizándolo desde la perspectiva de la teología y del derecho, sin omitir su opinión personal contraria a dicha esclavitud. Su doctrina creó escuela y debe ser considerado como el primer gran tratadista de la esclavitud de los negros.
