    Full Text Available A 14-month-old Hispanic female with a history of double-outlet right ventricle and developmental delay in the setting of recombinant chromosome 8 syndrome was referred for neurologic imaging. Brain MR revealed multiple abnormalities primarily affecting midline structures, including commissural dysgenesis, vermian and brainstem hypoplasia/dysplasia, an interhypothalamic adhesion, and an epidermoid between the frontal lobes that enlarged over time. Spine MR demonstrated hypoplastic C1 and C2 posterior elements, scoliosis, and a borderline low conus medullaris position. Presented herein is the first illustration of neuroimaging findings from a patient with San Luis Valley syndrome.

  7. Geologic Map of the San Luis Quadrangle, Costilla County, Colorado

    Science.gov (United States)

    Machette, Michael N.; Thompson, Ren A.; Drenth, Benjamin J.

    2008-01-01

    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.

  12. 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.

    Strasser, E.; Chiesa, J.

    2004-01-01

    The characteristics of three column profiles belonging to eolic sediments, assignated to Upper Holocene of the Depression of Conlara and oriental edge of San Luis range, comprising loessic materials and sandy loessoides, associated to aluvio-eolic and pedogenetic levels are texturally described. Lineal graphics of expression are used to visualize the textual variations according to the deph, those graphics are built according to the curve of frequency accumulated of the distribution of the size, using the parameters of rank in phi (Q) intervals and the half diameter expressed in microns. The interpretation of the succession in ecuatorial direction allows the inferences of the decrease of the size of grain from the planicie (on the east) towards the mountain region (on the west). The values of parameters of rank and statistiral parameters are presented, of all the succession although it is proposed that the Upper Holocene corresponds to the two upper meters [es

    Ulacco, Jose H

    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.

    The purpose of this study is to assess the commercial feasibility of producing between 76 and 189 million liters (20 and 50 million gallons) of ethanol annually in the San Luis Valley, Colorado using geothermal energy as the primary heat source. 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 (KGRA) 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 feedstock 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.

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

    Childhood overweight (OW) is a matter of public health concern because of its long-term impact on adulthood health. NF-E2-related factor 2 (Nrf-2) regulates the antioxidant/lipogenic response to a sustained positive energy balance that prevails during weight gain. Here we aimed at studying a possible link between OW and Nrf-2-dependent antioxidant/lipogenic response in a local population of boys at risk of metabolic complications. We measured clinical and biochemical parameters related to lipid metabolism, oxidative stress, and metabolic syndrome in a population of OW boys [body mass index (BMI) percentile ≥85(th) and Luis City, San Luis, Argentina. Compared to NW, OW boys had lower insulin sensitivity, an altered plasma lipid profile, and increased markers of oxidative stress and inflammatory fatty acids. OW boys also had a higher atherogenic index and peripheral insulin resistance than NW boys. We also found that glutathione peroxidase activity and the reduced glutathione to oxidized glutathione ratio were lower in OW boys than NW boys, suggesting that OW boys may have an altered antioxidant response to oxidative stress. Finally, Nrf-2 expression negatively correlated with metabolic syndrome parameters in OW boys. Our data suggest that OW boys have a reduced antioxidant and lipogenic response to a positive energy balance, resulting in oxidative stress, insulin resistance, and risk of developing metabolic complications. Our data also provide a rationale for nutritional interventions aimed at restoring Nrf-2 expression to reduce the risk of metabolic complications in OW boys.

    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.

    Bovine brucellosis (BB) is a zoonotic disease caused by Brucella abortus. BB is endemic in Argentina, where vaccination with Brucella abortus strain 19 is compulsory for 3-to-8 month-old heifers. The objectives of this study were to quantify the prevalence of BB and to identify factors associated with its occurrence, along with the spatial distribution of the disease, in the provinces of La Pampa and San Luis. A two-stage random sampling design was used to sample 8,965 cows (3,513 in La Pampa and 5,452 in San Luis) from 451 farms (187 in La Pampa and 264 in San Luis). Cow and herd prevalence were 1.8 % (95 % CI: 1.3-2.2; n = 157) and 19.7 % (95 % CI: 17.0-22.4; n = 89), respectively. Both cow-level and herd-level prevalence in La Pampa (2.4 and 26.0 %, respectively) were significantly higher than in San Luis (1.4 and 15.5 %, respectively). There were not differences between the proportions of reactive cattle compared to that obtained in a survey conducted in 2005. However, herd prevalence in La Pampa was significantly (P < 0.05) higher compared to that study. Disease was found to be spatially clustered in west La Pampa. The lower the bovine density and the calf/cow ratio, the higher odds of belonging to the cluster. The increase of farm prevalence in the last five years suggests that the disease is spreading and that control measures should be applied in the region. The cluster of infected farms was located in the west region of La Pampa. There, farms have lower animal densities and smaller cow/calf indices compared to the rest of the province. Although western La Pampa has more infected herds, within-farm prevalence was not higher, which suggests that the control program has been relatively successful in controlling the disease at the farm level, and/or that low animal density inherently results in low disease prevalence. Our results provide baseline information on the epidemiology of BB and its potential pattern of transmission in Argentina, which will ultimately

    Marine geology and geomorphology were mapped along the continental shelf and upper slope between Point Piedras Blancas and Pismo Beach, California. The map area is divided into the following three (smaller) map areas, listed from north to south: San Simeon, Morro Bay, and Point San Luis. Each smaller map area consists of a geologic map and the corresponding geophysical data that support the geologic mapping. Each geophysical data sheet includes shaded-relief multibeam bathymetry, seismic-reflection-survey tracklines, and residual magnetic anomalies, as well as a smaller version of the geologic map for reference. Offshore geologic units were delineated on the basis of integrated analysis of adjacent onshore geology, seafloor-sediment and rock samples, multibeam bathymetry and backscatter imagery, magnetic data, and high-resolution seismic-reflection profiles. Although the geologic maps are presented here at 1:35,000 scale, map interpretation was conducted at scales of between 1:6,000 and 1:12,000.

    Transient electromagnetic soundings were used to obtain information needed to refine hydrologic models of the San Luis Valley, Colorado. The soundings were able to map an aquitard called the blue clay that separates an unconfined surface aquifer from a deeper confined aquifer. The blue clay forms a conductor with an average resistivity of 6.9 ohm‐m. Above the conductor are found a mixture of gray clay and sand. The gray clay has an average resistivity of 21 ohm‐m, while the sand has a resistivity of greater than 100 ohm‐m. The large difference in resistivity of these units makes mapping them with a surface geophysical method relatively easy. The blue clay was deposited at the bottom of Lake Alamosa which filled most of the San Luis Valley during the Pleistocene. The geometry of the blue clay is influenced by a graben on the eastern side of the valley. The depth to the blue clay is greater over the graben. Along the eastern edge of valley the blue clay appears to be truncated by faults.

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

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

    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

    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.

    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.

    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.

    Background Although epidemiologic and socioeconomic criteria and biomedical risk factors indicate high-priority for tuberculosis (TB) control in Mexico, molecular epidemiology studies of the disease in the country are scarce. Methods Complete sociodemographic and clinical data were obtained from 248 of the 432 pulmonary TB (PTB) cases confirmed from 2006 to 2010 on the population under epidemiological surveillance in the state of San Luis Potosí, México. From most PTB cases with complete data Mycobacterium tuberculosis complex (MTC) isolates were recovered and their spoligotypes, lineages and families, geographic distribution and drug resistance determined. Results Pulmonary tuberculosis incidence ranged from 2.4 to 33.4 (cases per 100,000 inhabitants) in the six state sanitary jurisdictions that were grouped in regions of low (jurisdictions I-II-III), intermediate (jurisdictions IV-V) and high incidence (jurisdiction VI) with 6.2, 17.3 and 33.4 rates, respectively. Most patients were poor, 50-years-median-age males and housewives. Among the 237 MTC spoligotyped isolates, 232 corresponded to M. tuberculosis (104 spoligotypes in 24 clusters) and five to M. bovis. The predominant Euro-American lineage was distributed all over the state, the East-Asian lineage (Beijing family) in the capital city, the Indo-Oceanic (Manila family) in eastern localities, and M. bovis in rural localities. Conclusions In San Luis Potosí TB affects mainly poor male adults and is caused by M. tuberculosis and to a minor extent by M. bovis. There is great genotypic diversity among M. tuberculosis strains, the Euro-American lineage being much more prevalent than the Indo-Oceanic and East-Asian lineages. The frequency of resistant strains is relatively low and not associated to any particular lineage. PMID:23635381

    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. The sites of these monospecific and mixed woodlands with associated species, indicators of environmental variables

    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.

    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

    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.

    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.

    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

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

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

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

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

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

    The 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.

    Consumption of inorganic arsenic in drinking water at high levels has been associated with chronic diseases. Risk is less clear at lower levels of arsenic, in part due to difficulties in estimating exposure. Herein we characterize spatial and temporal variability of arsenic concentrations and develop models for predicting aquifer arsenic concentrations in the San Luis Valley, Colorado, an area of moderately elevated arsenic in groundwater. This study included historical water samples with total arsenic concentrations from 595 unique well locations. A longitudinal analysis established temporal stability in arsenic levels in individual wells. The mean arsenic levels for a random sample of 535 wells were incorporated into five kriging models to predict groundwater arsenic concentrations at any point in time. A separate validation dataset (n = 60 wells) was used to identify the model with strongest predictability. Findings indicate that arsenic concentrations are temporally stable (r = 0.88; 95 % CI 0.83-0.92 for samples collected from the same well 15-25 years apart) and the spatial model created using ordinary kriging best predicted arsenic concentrations (ρ = 0.72 between predicted and observed validation data). These findings illustrate the value of geostatistical modeling of arsenic and suggest the San Luis Valley is a good region for conducting epidemiologic studies of groundwater metals because of the ability to accurately predict variation in groundwater arsenic concentrations.

    To address childhood obesity, strategies are needed to maximize physical activity during the school day. The San Luis Valley Physical Education Academy was a public health intervention designed to increase the quality of physical education and quantity of moderate to vigorous physical activity (MVPA) during physical education class. Elementary school physical education teachers from 17 schools participated in the intervention. They received SPARK curriculum and equipment, workshops, and site coordinator support for 2 years. A pre/post/post within physical education teacher design was used to measure intervention effectiveness. System for Observing Fitness Instruction Time (SOFIT) and a physical education teacher survey were collected 3 times. MVPA increased from 51.1% to 67.3% over the 2-year intervention resulting in approximately 14.6 additional hours of physical activity over a school year and 4662 kcal or 1.33 lbs. of weight gain prevention. More time was spent on skill drills and less time on classroom management and free play. The San Luis Valley Physical Education Academy succeeded in increasing rural, low-income students' physical activity. The multicomponent intervention contributed to the program's success. However, cost-effective approaches are needed to disseminate and implement evidencebased practices aimed at increasing students' physical activity during the school day.

    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

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

    Within the Early Paleozoic Famatinian orogeny of Southern Sierras Pampeanas (Sierra de San Luis and Sierra de Cordoba), the post-orogenic granitoids are characterized by circular intrusions. The published Rb-Sr and K-Ar ages from plutons in the Sierra de San Luis range between 408 and 320 Ma (see synthesis in Llambias et al., 1998). The El Molle and Barroso plutons (Sims et al., 1997; Gonzalez and Sato, 2000) are the two main exposures of a post-orogenic intrusive complex located in the western area of the Sierra de San Luis basement. They also exhibit an overall circular map view of almost 8 km in diameter, and are emplaced in a metamorphic complex developed through pre-Famatinian (Proterozoic? to Early Paleozoic) to Famatinian (Early Paleozoic) orogenies (Gonzalez and Llambias, 1998; von Gosen and Prozzi, 1998). We are carrying out isotopic datings of the El Molle and Barroso plutons in order to contribute to the understanding of the magmatic and metamorphic evolution of the final stages of the Famatinian orogenic cycle in the Sierra de San Luis. The first results of the Sm-Nd, Rb-Sr and K-Ar dates are here presented (au)

    2016-02-01

    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 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.

    Please cite this paper as: Comas‐García et al. (2011) Mortality attributable to pandemic influenza A (H1N1) 2009 in San Luis Potosí, Mexico. Influenza and Other Respiratory Viruses 5(2), 76–82. Background  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. Objectives  To determine the impact of pandemic influenza A(H1N1) 2009 on mortality in a Mexican population. Methods  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. Results  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. Conclusions  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.

    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

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

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

    Full Text Available Abstract This research paper deals with the opinions of practitioners working in the field of health care, education and law in the city of San Luis on homosexual parenting, and its possible effects in the psychological development of children adopted by homosexual couples. A descriptive-exploratory study was conducted with the aim of making a preliminary approach to this issue, which made it possible to establish the common-sense knowledge referred to above. The sample was composed of 21 individuals, five pediatricians, five lawyers, five teachers and six psychologists. The purpose of this presentation is to communicate the results obtained in one of the four dimensions of the analysis. Said results were obtained before the implementation of the Egalitarian Marriage Act. The results obtained in relation to this dimension reveal that almost all homosexual couples should have the same rights as any other citizen, except that to forming a family by adopting a child. It is important to note that, when answering to the questions; many professionals did not know whether to adhere to the principles of their profession, or to their personal opinion.

    The association of human papillomavirus (HPV) types to neoplastic lesions increase as a function of their oncogenicity and the duration of the infection since lesion severity progresses from low-grade to high-grade and cancer. In an outbreak, the prevalence of the HPV type involved would increase and the proportion of the associated low-grade lesions would predominate over severe lesions. In this study, the prevalence of HPV types and their association to neoplastic lesions was determined in women subjected to colposcopy in San Luis Potosí, Mexico. DNA from high-risk (HR) and low-risk (LR) HPV types was identified by E6 nested multiplex PCR in cervical scrapes from 700 women with normal cytology, atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL) or invasive cervical cancer (CC). Overall HPV-DNA prevalence was 67.7 %, that of HR-HPV was 63.1 %, and that of LR-HPV was 21.3 %. The highest prevalence (78.2 %) occurred in the 15-24 year group, whereas that of single infections was 52 % and that of multiple infections (i.e., by 2-6 HPV types) was 48 %. The most prevalent HR types were HPV33 (33.1 %), HPV16 (16.6 %), HPV18 and HPV51 (6.7 % each). HR-HPV prevalence was 29.6 % in normal cytology, 26.7 % in ASCUS, 63.3 % in LSIL, 68.2 % in HSIL, and 90.5 % in CC. Three prevalence trends for HR-HPV types were found in neoplastic lesions of increasing severity: increasing (LSIL  CC) for HPV33. Two-thirds of the women subjected to colposcopy from 2007 to 2010 in San Luis Potosí have HPV infections which predominate in the 15-24 years group. Around half of the infections are by one viral type and the rest by 2-6 types. HPV33 is the most prevalent type, followed by HPV16. Overall HR-HPV prevalence increases with the severity of neoplastic lesions. HPV33 prevalence is highest in LSIL and its U-shaped trend with progressing neoplastic lesions

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

    The Sierra de San Luis forms the southern tip of the Eastern Sierras Pampeanas in central Argentina. Two narrow belts of low-grade phyllites and quartz arenites, i.e. the San Luis Formation, have accommodated part of the strain-related differential exhumation of the medium- to high-grade metamorphic domains that constitute to the basement complex of the sierra. Eleven phyllite samples were subjected to the K/Ar fine-fraction dating technique. Results are interpreted in relation to the Kübler index of the illites, which indicate epimetamorphic conditions for the majority of the samples. Obtained ages between 330 and 290 Ma cover a period of compressional tectonics in the late Mississippian (Visean/Serpukhovian boundary) followed by the subsidence during the formation of the Paganzo Basin in the provinces of La Rioja and San Luis. These tectonic movements are coincident with the Toco orogeny in northern Chile and southern Bolivia. This suggests that the older K/Ar ages document the compressional stage and that younger ages record the cooling of the basement during the subsequent extensional uplift of the basement.

    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.

    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.

    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.

    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.

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

    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.

    Human biomonitoring (HBM) is an appreciated tool used to evaluate human exposure to environmental, occupational or lifestyle chemicals. Therefore, the aim of this study was to evaluate the exposure levels for environmental chemicals in urine and blood samples of children from San Luis Potosí, Mexico (SLP). This study identifies environmental chemicals of concern such as: arsenic (45.0 ± 15.0 µg/g creatinine), lead (5.40 ± 2.80 µg/dL), t,t-muconic acid (266 ± 220 µg/g creatinine), 1-hydroxypyrene (0.25 ± 0.15 µmol/mol creatinine), PBDEs (28.0 ± 15.0 ng/g lipid), and PCBs (33.0 ± 16.0 ng/g lipid). On the other hand, low mercury (1.25 ± 1.00 µg/L), hippuric acid (0.38 ± 0.15 µg/g creatinine) and total DDT (130 ± 35 ng/g lipid) exposure levels were found. This preliminary study showed the tool's utility, as the general findings revealed chemicals of concern. Moreover, this screening exhibited the need for HBM in the general population of SLP.

    Interferometric Synthetic Aperture Radar (InSAR), a remote sensing technique for measuring centimeter-level surface deformation, is used to estimate hydraulic head in the confined aquifer of the San Luis Valley (SLV), Colorado. Reconstructing head measurements from InSAR in agricultural regions can be difficult, as InSAR phase data are often decorrelated due to vegetation growth. Analysis of 17 L-band ALOS PALSAR scenes, acquired between January 2007 and March 2011, demonstrates that comprehensive InSAR deformation measurements can be recovered over the vegetated groundwater basin with an improved processing strategy. Local skeletal storage coefficients and time delays between the head change and deformation are estimated through a joint InSAR-well data analysis. InSAR subsidence estimates are transformed to head changes with finer temporal and spatial resolution than is possible using existing well records alone. Both InSAR and well data suggest that little long-term water-storage loss occurred in the SLV over the study period and that inelastic compaction was negligible. The seasonal head variations derived from InSAR are consistent with the existing well data at most locations where confined aquifer pumping activity dominates. Our results demonstrate the advantages of InSAR measurements for basin-wide characterization of aquifer storage properties and groundwater levels over agricultural regions.

    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.

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

    Full Text Available This paper aims to study the intertextual traces dell Song of Songs in the work of Luis de León, San Juan de la Cruz and Juan Gelman from a particular point of view: the resonance in the vernacular of small biblical book as founder dimension of an experience spiritual, emotional and literary time. Choosing our corpus may surprise but, for one, would like to emphasize the importance of two pivotal moments in the reception of the Song: the Spanish Renaissance, whose approach to the Bible is enriched by new currents philological and exegetical of which Luis de León is a sublime representative; the late twentieth century in which an insistent intertextuality observed with sanjuanista work in one direction often foreign to Christian spirituality, as in the case of the Argentine Juan Gelman.

    The Sierra Madre Oriental region in the mexican state of San Luis Potosi is a relevant place for bird conservation at a country level. Therefore the main goal of this study was to analyze the geographic patterns of distribution and the conservation current state of the birds, to support the needs to expand the conservation areas in the future. Data was collected from various databases of zoological museums and collections, and field sampling methods conducted from January 2009 to May 2011. Potential distributions were modeled for 284 species using GARP software and then a map was developed to determine areas with favorable environmental characteristics for the distribution of species richness. Finally, the importance of conservation areas for the potential distribution of birds in the region was evaluated. A total of 359 species were recorded of which 71.4% are permanent residents, 19% are winter migrants and 4% are summer residents. From this total, 41 species were endemic, 47 were species at risk and 149 were neotropical migrants. The largest species richness correspond to oak forests, cloud forests, and tropical moist forests located at altitudes from 100m to 1 500m. Their potential distribution was concentrated towards the center and Southeast of the study area. Only 10% of areas with a high potential conservation was included in areas of priority for bird conservation (AICA) and just 3% of all potential areas were under some governmental category of protection. However, no conservation area has a management plan currently applied and monitored. The information generated is important for the development of management proposals for birds conservation in the region.

    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.

    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 conditions was common. Models for trees farther from the channel or over a deep water table explained 23–71% of SGI variability, and 4 of 5 contained a streamflow variable. Analyses using solely climate variables over longer time periods explained 17–85% of SGI variability, and 10 of 12 included a variable indexing summer precipitation. Three large, abrupt shifts in recent decades from wet to dry conditions (indexed by a seasonal Palmer 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 Cerritos and Río Verde aquifers in San Luis Potosí (central México) make up a very complex aquifer system that is seriously affected by the overexploitation and the high concentration of sulphates. Currently, it is partially closed for extraction causing a substantial decrease in per capita drinking water availability affecting to more than 50,000 inhabitants in the region. Therefore, a very comprehensive study has been proposed in order to evaluate not only the groundwater contamination distribution but also to better know the aquifer configuration and its main hydrogeological characteristics as well. These studies include a detailed geological reconnaissance, hydrogeochemical analyses and a geoelectrical characterization. The main goal is to assess the aquifer geometry and to identify the gypsum horizons causing the presence of higher concentrations of sulphates in drinking water. A total of 26 audiomagnetotelluric soundings were measured and modelled along profiles following a perpendicular direction to the NW regional trending. Two-dimensional resistivity models suggest the presence of a shallow conductive layer (C1) with resistivity values ranging from 10 to 20 Ohm.m. It is related to the upper aquifer with a very low exploitation potential. A less conductive horizon (C2; 50 Ohm.m) underlying the shallow aquifer could be related to a very fractured limestone horizon forming a confined aquifer in the middle of the valley. A very resistive layer (R1) is observed underlying C1 and C2 units. This strata shows higher resistivity values (>100 Ohm.m) and could be associated with a reefal limestone identified as El Abra Formation. Finally, a conductive layer (<100 Ohm.m) observed beneath this horizon could be related to the oldest stratigraphic unit outcropping on the region, the Guaxcamá Formation, a gypsum-enriched unit, that contributes to the presence of sulphates in the upper aquifers by dissolution processes.

    Arsenic is a carcinogen and epimutagen that threatens the health of exposed populations worldwide. In this study, we examined the methylation status of Alu and long interspersed nucleotide elements (LINE-1) and their association with levels of urinary arsenic in 84 Mexican children between 6 and 12 years old from two historic mining areas in the State of San Luis Potosí, Mexico. Urinary arsenic levels were determined by atomic absorption spectrophotometry and DNA methylation analysis was performed in peripheral blood leukocytes by bisulfite-pyrosequencing. The geometric mean of urinary arsenic was 26.44 µg/g Cr (range 1.93-139.35). No significant differences in urinary arsenic or methylation patterns due to gender were observed. A positive correlation was found between urinary arsenic and the mean percentage of methylated cytosines in Alu sequences (Spearman correlation coefficient r = 0.532, P < 0.001), and a trend of LINE-1 hypomethylation was also observed (Spearman correlation coefficient r = -0.232, P = 0.038) after adjustment for sex and age. A linear regression model showed an association with log-normalized urinary arsenic for Alu (β = 1.05, 95% CI: 0.67; 1.43, P < 0.001) and LINE-1 (β = -0.703, 95% CI: -1.36; -0.38, P = 0.038). Despite the low-level arsenic exposure, a subtle epigenetic imbalance measured as DNA methylation was detected in the leukocytes of Mexican children living in two historic mining areas. Environ. Mol.

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

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

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

    Middle Devonian granitoids intruded the Eastern Sierras Pampeanas basement ca. 600 km east of the inferred proto-Pacific margin of Gondwana along which a ca. 390 Ma collisional event developed. In the Sierra de San Luis, voluminous Middle Devonian (393-382 Ma) batholiths are composed of I- to A-type hybrid Monzonite and Granite suites. Shoshonite and subordinated high-K series, stocks, synplutonic dikes and enclaves make up the Monzonite Suite; rocks are metaluminous alkali-calcic magnesian porphyritic or equigranular monzonite, quartz monzonite, monzodiorite and scarce monzogabbro. High-K and subordinated shoshonite series metaluminous to mildly peraluminous magnesian alkali-calcic to calc-alkalic porphyritic or equigranular quartz monzonite, granodiorite, monzogranite and equigranular leucomonzogranites make up the Granite Suite plutons and batholiths. Only a small group of highly evolved granites are ferroan. SiO2 (46-62%), Cr, Ni, V, Sc, LILE, LREE, Th, Zr and variable, Sr/Y, (La/Yb)N and (Tb/Yb)N, smooth Eu/Eu*, moderate Na2O (ca 3.5), and troughs at Nb and Ta for Monzonite Suite rocks suggest an subduction-related enriched lithospheric mantle source. Sm-Nd data (TDM 0.98-1.08 Ga, εNd(380 Ma) 0.66-1.47) and 87Sr/86Sri (0.703520-0.704203) are compatible with an enriched mantle source. The metaluminous porphyritic quartz monzonite-monzogranite and the mildly peraluminous equigranular biotite monzogranites of the Granite Suite are characterized by relatively moderate Al2O3, CaO, and 87Sr/86Sri, high LILE, Cr, variable Sr/Y, (La/Yb)N and Eu/Eu* and low Rb/Sr ( 1.5, ASI 1.05-1.18, and Ga/Al 2.6-3.9, εNd(380 Ma) - 3.74 to - 3.95 and (87Sr/86Sr)i 0.710743-0.712955 which would point to metasedimentary or felsic igneous crustal sources.

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

    Science.gov (United States)

    Mix, Ken

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

    Full Text Available In recent years information and communication technologies are present in all sectors of our lives and the food and drink sector is no exception, so a diagnosis was made in this area in small and medium enterprises in the city of San Luis Potosí in the areas for the management and dissemination of their services, as they are currently at a disadvantage in front of large restaurant chains that have mobile applications, web pages and other applications. The research design applied is descriptive. Thirty-two MSMEs from the food and beverage sector in the city of San Luis Potosí were affiliated with the National Chamber of the restaurant and food industry (Canirac. The variables that were taken into consideration are: Use of computer equipment, ICT specialists, Internet access and use, Social Media, Electronic Commerce. The study found that most SMEs in the restaurant sector, use the social network Facebook as a means of disseminating services and promotions, However, they do not use all the potential that the social tool provides them, due to the lack of knowledge and lack of preparation to interact better with their customers and suppliers. In addition, most of the sample has the need to advertise through electronic means, through mobile phone applications.

    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.

  16. Tectonic Implications of Changes in the Paleogene Paleodrainage Network in the West-Central Part of the San Luis Basin, Northern Rio Grande Rift, New Mexico and Colorado, USA

    The San Luis Basin is the largest of extensional basins in the northern Rio Grande rift (>11,400 km2). The modern basin configuration is the result of Neogene deformation that has been the focus of numerous studies. In contrast, Paleogene extensional deformation is relatively little studied owing to a fragmentary or poorly exposed stratigraphic record in most areas. However, volcanic and volcaniclastic deposits exposed along the western margin of the basin provide the spatial and temporal framework for interpretation of paleodrainage patterns that changed in direct response to Oligocene basin subsidence and the migration of centers of Tertiary volcanism. The early Oligocene (34 to 30 Ma) drainage pattern that originated in the volcanic highlands of the San Juan Mountains flowed south into the northern Tusas Mountains. A structural and topographic high composed of Proterozoic rocks in the Tusas Mountains directed flow to the southeast at least as late as 29 Ma, as ash-flow tuffs sourced in the southeast San Juan Mountains are restricted to the north side of the paleohigh. Construction of volcanic highlands in the San Luis Hills between 30 and 28.5 Ma provided an abundant source of volcanic debris that combined with volcanic detritus sourced in the southeast San Juan Mountains and was deposited (Los Pinos Formation) throughout the northern Tusas Mountains progressively onlapping the paleotopographic high. By 29 Ma, subsidence of the Las Mesitas graben, a structural sub-basin, between the San Luis Hills and the southeast San Juan and northern Tusas Mountains is reflected by thick deposits of Los Pinos Formation beneath 26.5 Ma basalts. Regional tectonism responsible for the formation of the graben may have also lowered the topographic and structural high in the Tusas Mountains, which allowed development of a southwest-flowing paleodrainage that likely flowed onto the Colorado Plateau. Tholeiitic basalt flows erupted in the San Luis Hills at 25.8 Ma, that presently cap

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

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

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

    Full Text Available En este artículo, se analizan las razones que motivaron a un grupo de militares encabezados por el general Francisco Antonio Aguirre a inconformarse ante el desarrollo de las elecciones para gobernador en el año de 1869 ya que los miembros de la legislatura local, no declararon gobernador constitucional electo. Ante este escenario indefinido, los militares transgredieron el orden al iniciar un pronunciamiento para externar su inconformidad. El gobierno general intervino en la vida política interna de los potosinos al ordenar a una facción del ejército regular de la federación que sofocara a los pronunciados. El movimiento político tomó otra dimensión y los sublevados redactaron un Plan político en contra del presidente Benito Juárez y sus ministros. El movimiento se mantuvo vigente al iniciar 1870 así el gobierno general envió a San Luis Potosí al general Mariano Escobedo con el propósito de restablecer a las autoridades legítimas. Luego de conseguir su objetivo, Escobedo se postuló como gobernador y ganó las elecciones en ese año.

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

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

    Shiga toxin producing Escherichia coli (STEC), Salmonella spp., and Yersinia species was investigated in humans, animals, and foods in San Luis, Argentina. A total of 453 samples were analyzed by culture and PCR. The antimicrobial susceptibility of all the strains was studied, the genomic relationships among isolates of the same species were determined by PFGE, and the potencial virulence of Y. enterocolitica strains was analyzed. Yersinia species showed higher prevalence (9/453, 2.0%, 95% CI, 0.7–3.3%) than STEC (4/453, 0.9%, 95% CI, 0–1.8%) and Salmonella spp. (3/453, 0.7%, 95% CI, 0–1.5%). Y. enterocolitica and Y. intermedia were isolated from chicken carcasses (6/80, 7.5%, 95% CI, 1.5–13.5%) and porcine skin and bones (3/10, 30%, 95% CI, 0–65%). One STEC strain was recovered from human feces (1/70, 1.4%, 95% CI, 0–4.2%) and STEC stx1/stx2 genes were detected in bovine stools (3/129, 2.3%, 95% CI, 0–5.0%). S. Typhimurium was isolated from human feces (1/70, 1.4%, 95% CI, 0–4.2%) while one S. Newport and two S. Gaminara strains were recovered from one wild boar (1/3, 33%, 95% CI, 0–99%). The knowledge of prevalence and characteristics of these enteropathogens in our region would allow public health services to take adequate preventive measures. PMID:25177351

    Interferometric Synthetic Aperture Radar (InSAR) data from multiple satellite missions were combined to study the temporal and spatial variability of head and storage properties in a confined aquifer system on a decadal time scale. The area of study was a 4,500 km2 agricultural basin in the San Luis Valley (SLV), Colorado. We had available previous analyses of C-band ERS-1/2 data from June 1992 to November 2000, and L-band ALOS PALSAR data from October 2009 to March 2011. We used C-band Envisat data to fill in the time period from November 2006 to July 2010. In processing the Envisat data, we successfully employed a phase interpolation between persistent scatterer pixels to reduce the impact of vegetation decorrelation, which can significantly reduce the quality of C-band InSAR data over agricultural basins. In comparing the results from the L-band ALOS data and C-band Envisat data in a 10 month overlapping time period, we found that the shorter wavelength of C-band InSAR allowed us to preserve small deformation signals that were not detectable using L-band ALOS data. A significant result was the finding that the elastic storage properties of the SLV confined aquifer system remained stable over the 20 year time period and vary slowly in space, allowing us to combine InSAR data acquired from multiple missions to fill the temporal and spatial gaps in well data. The InSAR estimated head levels were validated with well measurements, which indicate little permanent water-storage loss over the study time period in the SLV.

    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.

  19. Effects of topographic position and geology on shaking damage to residential wood-framed structures during the 2003 San Simeon earthquake, western San Luis obispo county, California

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

  4. Carbonate clumped isotopes and in situ temperature monitoring for Holocene soils in the San Luis Valley, USA indicate springtime carbonate formation

    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

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

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

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

    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.

  20. 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

    This research was designed to analyze the possible associations of Arg389Gly ADRB1 and Trp64Arg ADRB3 polymorphisms in children with obesity. A cross-sectional study included 1,046 school-age Mexican participants (6-12 years old) from the cities of San Luis PotosÍ and León. Children were classified as non-obese or obese according to their body mass index (BMI) percentile; obese children had a BMI≥95th percentile for sex and age. Biochemical data were collected. Polymorphisms were detected using TaqMan qPCR assay. A logistic regression analysis was used to calculate the risk of obesity based on genotypes. Differences were found between groups where obese children had a significant increase in systolic and diastolic blood pressure, fasting plasma glucose, insulin, HOMA-IR, LDL-cholesterol, triglycerides, and lower HDL-cholesterol compared with the normal weight group (P<0.05). The distribution of allele frequency in the population was Arg= 87.4 and Gly= 12.6 (Hardy Weinberg equilibrium c 2 = 3.16 , P = 0.07 ); Trp= 81.5 and Arg= 18.5 (Hardy Weinberg equilibrium c 2 = 2.2, P = 0.14 ) for ADRB1 and ADRB3, respectively. Even though no different frequencies of Arg389Gly polymorphism between groups were found (P = 0.08), children carriers of one Gly389 ADRB1 allele had a risk for obesity of OR=1.40 (95%CI, 1.03-1.90, P = 0.03) after adjustment for age and gender. No other association was found for Trp64Arg ADRB3 polymorphism. Only the Arg389Gly ADRB1 polymorphism was associated with risk for obesity in Mexican children.

    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.

  20. Cauda equina syndrome in the dog: radiographic evaluation

    International Nuclear Information System (INIS)

    Morgan, J.P.; Bailey, C.S.

    1990-01-01

    Dogs with clinical signs typical of cauda equina syndrome require careful evaluation to determine the cause of the disease as this strongly influences choice of treatment. Possible aetiologies include congenital or developmental, inflammatory, traumatic, neoplastic, and degenerative lesions that may involve vertebrae, vertebral joints, intervertebral discs, spinal cord, spinal nerves, or meninges. It must be determined whether clinical signs are due to musculoskeletal or neurological disease before performing special radiographic procedures. Non-contrast radiography permits false-positive diagnosis of obvious degenerative changes involving the L-S disc that may be without clinical signs or permits a false-negative diagnosis due to the failure to appreciate soft tissue lesions not seen radiographically. Special radiographic techniques are recommended and include: (1) stress radiography, (2) discography, and (3) epidural myelography. Evaluation of the results of these studies assists in determining the cause of the cauda equina syndrome and the type of therapy required

    To evaluate MR findings of redundant nerve roots (RNR) of the cauda equina. 17 patients with RNR were studied; eight were men and nine were women, and their ages ranged from 46 to 82 (mean 63) years. Diagroses were established on the basis of T2-weighted sagittal and coronal MRI, which showed a tortuous or coiled configuration of the nerve roots of the cauda equina. MR findings were reviewed for location, magnitude, and signal intensity of redundant nerve roots, and the relationship between magnitude of redundancy and severity of lumbar spinal canal stenosis (LSCS) was evaluated. In all 17 patients, MR showed moderate or severe LSCS caused by herniation or bulging of an intervertebral disc, osteophyte from the vertebral body or facet joint, thickening of the ligamentum flavum, degenerative spondylolisthesis, or a combination of these. T2-weighted sagittal and coronal MR images well clearly showed the location of RNR of the cauda equina;in 16 patients(94%), these were seen above the level of constriction of the spinal canal, and in one case, they were observed below the level of constriction. T2-weighted axial images showed the thecal sac filled with numerous nerve roots. The magnitude of RNR was mild in six cases (35%), moderate in five cases (30%), and severe in six cases (35%). Compared with normal nerve roots, the RNR signal on T2-weighted images was iso-intense. All patients with severe redundancy showed severe LSCS, but not all cases with severe LSCS showed severe redundancy. Redundant nerve roots of cauda equina were seen in relatively older patients with moderate or severe LSCS and T2-weighted MR images were accurate in identifying redundancy of nerve roots and evaluating their magnitude and location

    Cauda equina syndrome (CES) is an uncommon entity. Symptoms include bowel and bladder dysfunction, saddle anesthesia, and varying degrees of lower limb motor and sensory disturbances. The consequences of delayed diagnosis can be devastating, resulting in bowel and bladder incontinence and lower limb paralysis. There is little in literature regarding abdominal pain as a significant feature of the initial presentation of CES. We present the case of a 32-year-old woman with CES who presented to the emergency department with gradually worsening lower abdominal pain.

    2012-02-01

    We describe a case of bilateral weakness of the lower limbs, sensory disturbance and intermittent urinary incontinence, secondary to untreated Gitelman\\'s syndrome, in a 42-year-old female who was referred with presumed cauda equina syndrome. On examination, the power of both legs was uniformly reduced, and the perianal and lower-limb sensation was altered. However, MRI of the lumbar spine was normal. Measurements of serum and urinary potassium were low and blood gas analysis revealed metabolic alkalosis. Her symptoms resolved following potassium replacement. We emphasise the importance of measurement of the plasma and urinary levels of electrolytes in the investigation of patients with paralysis of the lower limbs and suggest that they, together with blood gas analysis, allow the exclusion of unusual causes of muscle weakness resulting from metabolic disorders such as metabolic alkalosis.

    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.

She was suspected to have pulmonary embolism (PE and was treated with low-molecular-weight heparin (LMWH and aspirin. She had computerized tomographic pulmonary angiography on next day, which ruled out any evidence of PE, until she was continued on LMWH. Three days later, she developed progressive right leg weakness and loss of sphincter control and patchy loss of sensation from T10 and below. She was seen by neurologist and had an MRI scan, which showed extensive subdural clot compressing the conus and lower half of the thoracic cord. She underwent T9-L1, L3, L5-S1 laminectomies, and evacuation and decompression of the clot. She showed very slight recovery following the surgery and left with residual paraparesis. This case is reported to raise awareness among intensivists to be cautious in establishing the diagnosis before prescribing the LMWH and be vigilant to diagnose cauda equina syndrome and treat promptly to avoid residual neurological problems.

    Low back pain during pregnancy is a common cause of medical consultation. Although back pain is very common, the incidence of low back pain secondary to lumbar disk herniation in pregnancy is low (1: 10,000). Cauda equina syndrome from lumbar disk herniation is a serious complication. The delay in diagnosis and treatment can be a cause of chronic disability secondary to neurological sequelae. Numerous cases of disk herniation in pregnancy have been reported, however the association of a cauda equina syndrome as a result of disk herniation is rare. A case is presented of cauda equina syndrome in a pregnant woman at 12-week gestation. Copyright © 2015 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Abstract Introduction Medulloblastoma is one of the most common pediatric brain malignancies. The usual presenting clinical features are related to posterior fossa syndrome or/and hydrocephalus. Cauda equina syndrome is a very rare presentation for this disease. Case presentation We describe the case of a three-year-old boy with cauda equina syndrome as the initial presenting clinical feature for medulloblastoma. He was initially diagnosed as having a spinal tumor by magnetic resonance imaging scan. Subsequently, a cranial magnetic resonance imaging scan revealed a posterior fossa tumor with features of dissemination. He had substantial improvement after treatment. This case report is complemented by a literature review related to this unusual presentation. Conclusions Medulloblastoma primarily presenting with cauda equina syndrome is very rare. However, spinal drop metastasis should be considered in the pediatric age group to avoid suboptimal management.

    1992-01-01

    Electromyography (EMG), L7-S1 discography and epidurography were investigated in 15 dogs with clinical signs of cauda equina dysfunction and in 7 control dogs without such clinical signs. Electromyography of paraspinal and pelvic limb muscles was done in 13 of 15 affected dogs. An L7-S1 discogram followed by an epidurogram was performed in all 22 dogs using 20% iopamidol. Results of discograms, epidurograms, and gross necropsy examinations were normal in six of seven control dogs. The one dog in which these studies were abnormal had a mild L7-S1 disc protrusion that did not result in nerve root compression at necropsy. Electromyographic analysis was 100% accurate in predicting the presence or absence of cauda equina disease. None of the results of discograms were falsely negative. Twelve of 15 discograms in clinically affected dogs indicated dorsal disc protrusion, but 2 of these protrusions were found to be noncompressive at surgery (13% error). Abnormal epidurograms occurred in 9 of 15 clinically affected dogs. There was one false positive and two false negatives (20% error). Electromyography was a sensitive screening technique for the presence of cauda equina disease. Discography may be more sensitive for detection of L7-S1 disc protrusion than epidurography. An abnormal radiographic contrast study of the cauda equina may only be useful when combined with an abnormal EMG

    An 8-year-old spayed female border collie dog was diagnosed with an invasive pituitary macrotumor. Five months after radiation therapy, the patient developed paraparesis and lumbosacral pain. Necropsy revealed a pituitary carcinoma with cauda equina drop metastasis. In cases of pituitary masses, meningeal dissemination should be considered if neurologic status declines.

    Full Text Available Leptomeningeal carcinomatosis (LMC is a diffuse or multifocal malignant infiltration of the pia matter and arachnoid membrane. The most commonly reported cancers associated with LMC are breast, lung, and hematological malignancies. Patients with LMC commonly present with multifocal neurological symptoms. We report a case of LMC secondary to gastroesophageal junction cancer present initially with cauda equina syndrome. A 51-year-old male patient with treated adenocarcinoma of the gastroesophageal junction presented with left leg pain, mild weakness, and saddle area numbness. Initial radiological examinations were unremarkable. Subsequently, he had worsening of his leg weakness, fecal incontinence, and urine retention. Two days later, he developed rapidly progressive cranial neuropathies including facial diplegia, sensorineural hearing loss, dysarthria, and dysphagia. MRI with and without contrast showed diffuse enhancement of leptomeninges surrounding the brain, spinal cord, and cauda equina extending to the nerve roots. Cerebrospinal fluid cytology was positive for malignant cells. The patient died within 10 days from the second presentation. In cancer patients with cauda equina syndrome and absence of structural lesion on imaging, LMC should be considered. To our knowledge, this is the first case of LMC secondary to gastroesophageal cancer presenting with cauda equina syndrome.

  15. The Effects of Ocean Acidification on Feeding and Contest Behaviour by the Beadlet Anemone Actinia equina

    Increasing concentrations of atmospheric carbon dioxide are causing oceanic pH to decline worldwide, a phenomenon termed ocean acidification. Mounting experimental evidence indicates that near-future levels of CO2 will affect calcareous invertebrates such as corals, molluscs and gastropods, by reducing their scope for calcification. Despite extensive research into ocean acidification in recent years, the effects on non-calcifying anthozoans, such as sea anemones, remain little explored. In Western Europe, intertidal anemones such as Actinia equina are abundant, lower trophic-level organisms that function as important ecosystem engineers. Changes to behaviours of these simple predators could have implications for intertidal assemblages. This investigation identified the effects of reduced seawater pH on feeding and contest behaviour by A. equina. Video footage was recorded for A. equina feeding at current-day seawater (pH 8.1), and the least (pH 7.9) and most (pH 7.6) severe end-of-century predictions. Footage was also taken of contests over ownership of space between anemones exposed to reduced pH and those that were not. No statistically significant differences were identified in feeding duration or various aspects of contest behaviour including initiating, winning, inflating acrorhagi, inflicting acrorhagial peels and contest duration. Multivariate analyses showed no effect of pH on a combination of these variables. This provides contrast with other studies where anemones with symbiotic algae thrive in areas of natural increased acidity. Thus, novel experiments using intraspecific contests and resource-holding potential may prove an effective approach to understand sub-lethal consequences of ocean acidification for A. equina, other sea anemones and more broadly for marine ecosystems.

    Full Text Available Background. Chronic inflammatory demyelinating polyneuropathy (CIDP is a treatable disimmune neuropathy, which accurate diagnostics and treatment are essential to improve a long-lasting  prognosis and prevent invalidization. In atypical cases and  differential diagnosis extra investigations are needed, including neuroimaging.Objective. Evaluating the diagnostic role of the cauda equina magnetic resonance imaging (MRI in CIDP.Materials and methods. 8 patients with CIDP according to European Federation of Neurological Societies and Peripheral Nerve Society criteria were originally included in the main cohort: 6  patients with definitive CIDP, 1 patient – with possible CIDP; in 1  patient later mixed crioglobulinemia, associated with hepatitis C was  later diagnosed. MRI with contrast enhancement of the cauda equina was performed in all primary included patients in the main cohort  and in 8 controls with metabolic polyneuropathy. In 12 months MRI was repeated in the main cohort patients.Results. The enlargement of the nerve roots of the cauda equina and nodular hypertrophy was demonstrated in all CIDP patients, and in none of the control subjects. The extensiveness of qualitative  changes correlated with disease duration. All CIDP patients with root hypertrophy had gadolinium enhancement and its severity did not  correlate with disease activity. Contrast enhancement in roots of the  control group patients was explained by the medullary artery phenomenon.Conclusion. MRI of the cauda equina with contrast improves the diagnostic of CIDP, but does not depict the activity of the disease. MRI in CIDP is a promissing technique, requiring further investigation and standardization.

    Evaluation of Krabbe disease burden and eligibility for hematopoietic stem cell transplantation are often based on neuroimaging findings using the modified Loes scoring system, which encompasses central but not peripheral nervous system changes. We show that quantitative evaluation of thickened cauda equina nerve roots may improve the evaluation of Krabbe disease and therapeutic guidance. Lumbar spine MRI scans of patients obtained between March 2013 and September 2013 were retrospectively evaluated and compared to those of controls. Quantitative evaluation of cauda equina roots was performed on the axial plane obtained approximately 5 mm below the conus medullaris. The largest nerves in the right and left anterior quadrants of the spinal canal were acquired. Fifteen symptomatic patients with Krabbe disease (5-44 months old) and eleven age-matched controls were evaluated. The average areas (mm{sup 2}) of anterior right and left nerves were 1.40 and 1.23, respectively, for patients and 0.61 and 0.60 for controls (differences: 0.79 and 0.63; p < 0.001). Cauda equina nerve root thickening is associated with Krabbe disease in both treated and untreated patients. Adding lumbar spine MRI to the current neurodiagnostic protocols, which fails to account for peripheral nerve abnormalities, will likely facilitate the diagnosis of Krabbe disease. (orig.)

    It has been reported that disturbance of blood flow arising from circumferential compression of the cauda equina by surrounding tissue plays a major role in the appearance of neurogenic intermittent claudication (NIC) associated with lumbar spinal canal stenosis (LSCS). We created a model of LSCS to clarify the mechanism of enhancement within the cauda equina on gadolinium-enhanced MR images from patients with LSCS. In 20 dogs, a lumbar laminectomy was performed by applying circumferential constriction to the cauda equina by using a silicon tube, to produce 30% stenosis of the circumferential diameter of the dural tube. After 1 and 3 weeks, gadolinium and Evans blue albumin were injected intravenously at the same time. The sections were used to investigate the status of the blood-nerve barrier function under a fluorescence microscope and we compared gadolinium-enhanced MR images with Evans blue albumin distribution in the nerve. The other sections were used for light and transmission electron microscopic study. In this model, histologic examination showed congestion and dilation in many of the intraradicular veins, as well as inflammatory cell infiltration. The intraradicular edema caused by venous congestion and Wallerian degeneration can also occur at sites that are not subject to mechanical compression. Enhanced MR imaging showed enhancement of the cauda equina at the stenosed region, demonstrating the presence of edema. Gadolinium-enhanced MR imaging may be a useful tool for the diagnosis of microcirculatory disorders of the cauda equina associated with LSCS.

    A readability and quality control Internet-based study using recognized quality scoring systems. To assess the readability and quality of Internet information relating to cauda equina syndrome accessed through common search engines. Access to health-related Internet information has increased dramatically during the past decade. A significant proportion of this information has been demonstrated to be set at too high a level for general comprehension. Despite this, searching for health-related information is now the third most popular online activity. A total of 125 cauda equina syndrome Web sites were analyzed from the 5 most popular Internet search engines: Google, Bing, Yahoo, Ask, and AOL. Web site authorship was classified: academic, physician, medico-legal, commercial, or discussion/social media. Readability of each Web site was assessed using the Flesch Reading Ease score, the Flesch-Kincaid grade level, and the Gunning Fog Index. Quality was calculated using the DISCERN instrument and The Journal of the American Medical Association benchmark criteria. The presence of HON-code certification was also assessed. Fifty-two individual Web sites were identified and assessed. The majority of Web sites were academic or physician compiled (53.8%; 28/52); however, a significant minority of Web sites were medico-legal related (19.2%; 10/52). Just 13.5% (7/52) of Web sites were at or below the recommended sixth-grade readability level. HON-code certified Web sites achieved significantly greater DISCERN (P = 0.0006) and The Journal of the American Medical Association (P = 0.0002) scores. Internet information relating to cauda equina syndrome is of variable quality and largely set at an inappropriate readability level. Given this variability in quality, health care providers should direct patients to known sources of reliable, readable online information. Identification of reliable sources may be aided by known markers of quality such as HON-code certification.

    Hereditary motor and sensory neuropathy (HMSN) is thought to almost exclusively affect the peripheral nervous system. We report the case of a 48-year-old patient with a longstanding history of HMSN type I who developed signs and symptoms of a cauda equina compression and of a central nervous system relapsing-remitting demyelinating white matter disease. Gross enlargement of the cauda equina fibers was detected by MR imaging of the lumbar spine. Cranial MR imaging revealed demyelinating white matter lesions. This case suggests that peripheral neuropathic mechanisms may also affect the central myelin in HMSN type I

    Neurolymphomatosis is a rare disorder characterised by infiltration of neoplastic lymphocytes into the peripheral nervous system. A wide variety of symptoms can manifest depending on its nature and location, making its diagnosis a real challenge. Treatment is based on methotrexate, although various chemotherapy regimens are currently available for patients with systemic disease. We present the case of a male patient with neurolymphomatosis of the cauda equina, together with a review of all cases published to date. Copyright © 2017 Sociedad Española de Neurocirugía.

    An adult nematode was grossly identified in the meninges of a Malayan sambar (Rusa unicolor equina), with numerous microfilariae associated with encephalitis and vasculitis on histopathology. The nematode was confirmed to be Elaeophora schneideri by sequencing a portion of the 18S rRNA gene. Our report highlights the potential for aberrant migration of E. schneideri in exotic deer species and the use of advanced testing to specifically identify this metazoan parasite, avoiding misidentification of Parelaphostrongylus tenuis. © 2016 The Author(s).

    Full Text Available A 14-year-old boy underwent emergency debridement surgery of right foot under spinal anaesthesia. Four hours after the surgery, the patient developed symptoms of cauda equina syndrome (CES. Postoperative magnetic resonance imaging of the patient′s spine suggested underlying tubercular arachnoiditis. The boy was started on intravenous methylprednisolone and antitubercular therapy. He responded to the therapy and recovered completely in 2 weeks without any residual neurological deficits. We suggest that underlying pathological changes in the subarachnoid space due to tubercular arachnoiditis contributed to maldistribution of the local anaesthetic drug leading to CES.

    1981-06-01

    A case of the cauda equina syndrome complicating ankylosing spondylitis (AS) is described. An unusual feature of this case was the relapsing and remitting nature of the condition, but there is sufficient evidence to explain the clinical picture on the basis of a recurrent intraspinal inflammatory process. The clinical and radiological features are similar to those of a further 28 reported in the literature. An electromyogram (EMG) proved important in defining the extent of neurological involvement. Computerised tomography (CT) showed marked laminar erosion and no bony exit foramen encroachment. We believe that the clinical diagnosis of this condition can be adequately confirmed with plain radiology, EMG, and CT scan.

CEI rarely leads to neurologic complications. We report a case of persistent cauda equina syndrome after CEI. A 44-year-old male patient with severe L4 and L5 spinal stenosis underwent CEI for low-back pain and sciatica. The CEI solution consisted of bupivacaine, hyaluronidase, triamcinolone acetonide, and normal saline. He experienced motor weakness and sensory loss in both lower extremities and neurogenic bladder for more than 1 year after the procedure. His ankle dorsiflexors, big-toe extensors, and ankle plantar flexors on both sides were checked and categorized as motor-power Medical Research Council grade 0. His bilateral ankle-jerk reflection was absent. An electrophysiological study showed lumbosacral polyradiculopathy affecting both sides of the L5 and S1 nerve roots. A urodynamic study revealed hypoactive neurogenic bladder affecting both sacral roots. Keywords: epidural injection, cauda equina syndrome, complications

  10. High in situ repeatability of behaviour indicates animal personality in the beadlet anemone Actinia equina (Cnidaria.

    Directory of Open Access Journals (Sweden)

    Mark Briffa

    Full Text Available 'Animal personality' means that individuals differ from one another in either single behaviours or suites of related behaviours in a way that is consistent over time. It is usually assumed that such consistent individual differences in behaviour are driven by variation in how individuals respond to information about their environment, rather than by differences in external factors such as variation in microhabitat. Since behavioural variation is ubiquitous in nature we might expect 'animal personality' to be present in diverse taxa, including animals with relatively simple nervous systems. We investigated in situ startle responses in a sea anemone, Actinia equina, to determine whether personalities might be present in this example of an animal with a simple nervous system. We found very high levels of repeatability among individuals that were re-identified in the same locations over a three week sampling period. In a subset of the data, where we used tide-pool temperature measurements to control for a key element of variation in microhabitat, these high levels of repeatability remained. Although a range of other consistent differences in micro-habitat features could have contributed to consistent differences between the behaviour of individuals, these data suggest the presence of animal personality in A. equina. Rather than being restricted to certain groups, personality may be a general feature of animals and may be particularly pronounced in species with simple nervous systems.

    2005-01-01

    A radiographic study was conducted to determine the incidence of redundant nerve roots of the cauda equina (RNR) in neurologically asymptomatic patients, and to clarify whether RNR has an impact on the clinical symptom. 50 patients who had spine disease such as spondylosis and compression fracture were examined by MRI. They didn't have neurological symptom such as sciatica, leg numbness, and motor weakness of lower extremities. There were 18 men and 32 women, and their mean age was 72.4 years (range: 32-87 years). RNR was found in 18 of the 50 patients (36.0%) and in a higher percentage of the patients who had lumber spinal canal stenosis. We concluded that RNR was only a morphological change of the cauda equine and had little effect on the neurological symptom. (author)

    Bardet–Biedl syndrome (BBS) is a rare, autosomal-recessive, debilitating genetic disorder, which can present with multitudinous systemic clinical features including rod-cone dystrophy, polydactyly, Frohlich-like central obesity, mental retardation, hypogonadism, and renal anomalies. Diverse neuromuscular manifestations in patients afflicted by this heterogeneous disorder include ataxia, cervical, and thoracic canal stenoses, presenting as spastic quadriparesis and other gait disturbances. We report a young patient with BBS, who had presented with acute flaccid paraparesis due to severe primary lumbar canal stenosis. She underwent immediate lumbar decompression and discectomy following which she recovered significantly. Acute cauda equina syndrome due to primary lumbar canal stenosis has not been reported as a clinical feature of BBS previously. PMID:28566787

    Full Text Available A 38-year-old man presented with a one-month history of muscle weakness and dysesthesia in the lower extremities, urinary retention, and urinary tract infection after lumbar burst fracture resulted from high fall. During the rehabilitation in our hospital, he had arthritis in both the ankle and knee. However, the patient was treated as gouty arthropathy initially. The arthritis was completely remitted in a few days after the patient was diagnosed as reactive arthritis and started with sulfasalazine therapy and there was no recurrence during 4 months of follow-up. Based on this case, early recognition of reactive arthritis is of major importance to avoid delayed initiation of appropriate treatment in the patients with polyarthritis secondary to neurogenic bladder following cauda equina injury after spine fracture.

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.

  19. La Escalerilla pluton, San Luis Argentina: The orogenic and post-orogenic magmatic evolution of the famatinian cycle at Sierras de San Luis

    Field relationships, geochemical analysis and two new absolute ages (LA-MC-ICP-MS U/Pb-zircon) allow the division of the La Escalerilla pluton (previously considered to be a single granitic body) into two different plutons: a new La Escalerilla pluton (s.s.), dated at 476.7 ± 9.6 Ma, that represents the northern portion, and the El Volcán pluton, dated at 404.5 ± 8.5 Ma, located in the southern sector. The La Escalerilla pluton is composed of three facies: (1) biotite-bearing granodiorite, (2) porphyritic biotite-bearing granite, and (3) porphyritic two micas-bearing leucogranite, being the presence of late-magmatic dykes in these facies common. The El Volcán pluton is composed of two main facies: 1) porphyritic biotite-bearing granite, and 2) two micas-bearing leucogranite, but amphibole-bearing monzodioritic and tonalititic mega-enclaves are also common, as well as some dykes of amphibole and clinopyroxene-bearing syenites. A peculiarity between the two plutons is that their most representative facies (porphyritic biotite-bearing granites) have, apart from different absolute ages, distinctive geochemical characteristics in their concentrations of trace elements; the La Escalerilla granite is comparatively poorer in Ba, Sr, Nb, La, Ce, P, and richer in Rb, Tb, Y, Tm and Yb. The El Volcán granite is notably enriched in Sr and depleted in Y, resulting in high Sr/Y ratios (12.67-39.08) compared to the La Escalerilla granite (1.11-2.41). These contrasts indicate that the separation from their sources occurred at different depths: below 25 km for the La Escalerilla, and above 30 km for the El Volcán. Moreover, the contrasts allow us to interpret a thin crust linked to an environment of pre-collisional subduction for the first case, and a thickened crust of post-collisional environment for the second, respectively.

    With the celebration of the centenary of the birth of Dr. Luis Cifuentes Delatte, due to his great scientific personality, we want to emphasize two features that, taken from his works and memories, we consider have not been emphasized enough: his role as historian of urology, both for the histories he narrated of his life experiences and the historical exposition of several pathologies, and also his teaching as professor of several generations of urologists, with the objective of trying to get to know his great human quality as he demonstrated over his life and showed in his writings. We review his books and works, lectures and published papers, in addition the news about his person we have collected from the media, and after analysis, mainly of his memories, we extract data reflecting his personality, and they way he thought and behaved. Since he was young he went with his father to the international urology meetings where he met a great number of personalities in the World of Urology; he extended his training with them, and later on they got to have a great relationship. He travelled around Europe and United States before and after Second World War, respectively, with stays in the most prestigious centers, which he described meticulously. He also reported his activity during the first two years he directed the Department of Urology at the Hospital La Princesa in Madrid and cited the series of collaborators he had. In his research works he made an ample description of historical development as introduction to the various pathologies he analyzed in depth. The reading of the narration of his trips, that he did in the convulse International time he lived, offers details which enable us to know firsthand the situation of urology and the human side of the actors he had relation with, and the social life they had, in addition to data about their families and daily life. As a researcher in transcendental chapters in urological pathology we emphasize his historical

    Extramedullary hematopoiesis (EMH) is occasionally reported in idiopathic myelofibrosis and is generally found in the liver, spleen, and lymph nodes several years after diagnosis. Myelofibrosis presenting as spinal cord compression, resulting from EMH tissue is very rare. A 39-yr-old man presented with back pain, subjective weakness and numbness in both legs. Sagittal magnetic resonance imaging showed multiple anterior epidural mass extending from L4 to S1 with compression of cauda equina and nerve root. The patient underwent gross total removal of the mass via L4, 5, and S1 laminectomy. Histological analysis showed islands of myelopoietic cells surrounded by fatty tissue, consistent with EMH, and bone marrow biopsy performed after surgery revealed hypercellular marrow and megakaryocytic hyperplasia and focal fibrosis. The final diagnosis was chronic idiopathic myelofibrosis leading to EMH in the lumbar spinal canal. Since there were no abnormal hematological findings except mild myelofibrosis, additional treatment such as radiothepary was not administered postoperatively for fear of radiotoxicity. On 6 month follow-up examination, the patient remained clinically stable without recurrence. This is the first case of chronic idiopathic myelofibrosis due to EMH tissue in the lumbar spinal canal in Korea. PMID:18162730

    Elsberg syndrome (ES) is an established but often unrecognized cause of acute lumbosacral radiculitis with myelitis related to recent herpes virus infection. We defined ES, determined its frequency in patients with cauda equina syndrome (CES) with myelitis, and evaluated its clinical, radiologic, and microbiologic features and outcomes. We searched the Mayo Clinic medical records for ES and subsequently for combinations of index terms to identify patients with suspected CES and myelitis. Our search yielded 30 patients, 2 diagnosed with ES and an additional 28 with clinical or radiologic evidence of CES retrospectively suspected of having ES. We classified patients in 5 groups according to diagnostic certainty. MRI and EMG confirmed that 2 had only myelitis, 5 only radiculitis, and 16 both. Two had preceding sacral herpes infection and 1 oral herpes simplex. Spinal cord lesions were commonly multiple, discontinuous, not expansile, and centrally or ventrally positioned. Lesions generally spared the distal conus. Nerve root enhancement was occasionally prominent and was smooth rather than nodular. Lymphocytic CSF pleocytosis was common. Thirteen patients (43%) had viral isolation studies, which were commonly delayed; the delay may have accounted for the low rate of viral detection. Acyclovir was administered to 6 patients. Most patients recovered with sequelae; 1 patient experienced encephalomyelitis and died. ES is a definable condition likely responsible for 10% of patients with combined CES and myelitis. Radiologic findings are not entirely specific but may help in differentiating ES from some competing diagnostic considerations. We propose criteria to facilitate diagnosis.

  8. San Marino.

    1985-02-01

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

    Cooling rates can be used to constrain the unroofing history of plutonic-metamorphic system. Geocronological cooling rates (Spear and Parrish, 1996) can be unravelled using age calculations on minerals that were open systems and subsequently passed through their closure temperatures (Dodson, 1973) during cooling. Several age determinations on different minerals are needed in order to accurately constrain the cooling path of a pluton (Hodges 1991, Spear and Parrish, 1996 and references therein). Isotopic open-system behaviour in minerals can be modelled as volume diffusion process (Hodges, 1991 and references therein), which depends on the cooling rate of the whole system. We present the first results on the calculation of the cooling rate of the Renca batholith on the basis of the combination of both thermometric calculations and available crystallization and cooling ages (au)

    2012-01-01

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

  11. 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.

    Immunohistochemical and behavioral study using a rat model of acute cauda equina syndrome (CES). To determine the effect of duration of extradural cauda equina compression (CEC) on bladder, sensory, and motor functions. Cauda equina syndrome is a devastating injury treated with surgical decompression. Controversy exists regarding the optimal timing of surgery. Animal models of CES have focused on motor recovery but have not evaluated pain behavior or bladder function. A 4-mm balloon-tipped Fogarty catheter was inserted between the fifth and sixth lumbar lamina into the dorsal epidural space and inflated to compress the nerve roots at the L5 level. Maximal inflation was maintained at a constant balloon pressure of 304 Kpa for 1 or 4 hours. The catheter was inserted but not inflated in sham animals. During a 4-week period, pain behavior, bladder function, and locomotor function were assessed. Postmortem bladders and the lesion site were collected for analysis. Mechanical allodynia was 2-fold greater in 1-hour CEC rats than 4-hour CEC (P=0.002) and sham-operated (P=0.001) rats at 4 weeks after injury. Hind limb locomotor function was not different between groups at 4 weeks after injury. Both the 1-hour and 4-hour CEC group rats retained greater volumes of urine than the sham-operated rats throughout the 4-week period (P<0.05). At 4 weeks, bladder weight and volume were 2-fold greater in the 4-hour CEC group than in the 1-hour CEC group (P=0.006 and P=0.01, respectively). Histology of the bladder wall revealed an overall thinning after 4-hour CEC. Histology of the lesion site revealed a greater overall severity of injury after 4-hour CEC than after 1-hour CEC (P=0.04) and sham operation (P=0.002). Our data suggest that recovery of motor function is less affected by the timing of decompression compared with bladder function and pain behavior. Early decompression preserved bladder function but was associated with allodynia. N/A.

During late 1940 and early 1941 an epizootic of encephalomyelitis occurred in the Municipio (County of Peçanha, which is located in the east central part of the State of Minas Gerais. Sera were collected from eighteen horses and mules which had passed through the epizootic, and tested for neutralizing antibodies to the St. Louis encephalitis virus and to the eastern and western strains of equine encephlomyelitis virus. None of the sera contained demonstrable antibodies to the St. Louis or western equine encephalomyelitis viruses; fourteen of the eighteen sera, however, possessed antibodies to the eastern strain. Only one of the twenty control sera, obtained from adjacent areas, was found to contain antibodies for the eastern strain, and this one also came from the Municipio of Peçanha. It is concluded that the eastern strain of equine encephlomyelitis virus occurs also in Brazil and is not confined to North America.

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

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.

    “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”.

    Full Text Available Abstract Background Reduction of blood flow is important in the induction of neurogenic intermittent claudication (NIC in lumbar spinal canal stenosis. PGE1 improves the mean walking distance in patients with NIC type cauda equina compression. PGE1 derivate might be effective in dilating blood vessels and improving blood flow in nerve roots with chronically compressed cauda equina. The aim of this study was to assess whether PGE1 derivate has vasodilatory effects on both arteries and veins in a canine model of chronic cauda equina compression. Methods Fourteen dogs were used in this study. A plastic balloon inflated to 10 mmHg was placed under the lamina of the 7th lumbar vertebra for 1 week. OP-1206-cyclodextrin clathrate (OP-1206-CD: prostaglandin E1 derivate was administered orally. The blood vessels of the second or third sacral nerve root were identified using a specially designed surgical microscope equipped with a video camera. The diameter of the blood vessels was measured on video-recordings every 15 minutes until 90 minutes after the administration of the PGE1 derivate. Results We observed seven arteries and seven veins. The diameter and blood flow of the arteries was significantly increased compared with the veins at both 60 and 75 minutes after administration of the PGE1 derivate (p Discussion The PGE1 derivate improved blood flow in the arteries but did not induce blood stasis in the veins. Our results suggest that the PGE1 derivate might be a potential therapeutic agent, as it improved blood flow in the nerve roots in a canine model of chronic cauda equina compression.

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.

    Hodgkin's disease may involve the spine as a setting of the advanced disease. An initial manifestation of Hodgkin's disease in spine is extremely rare and the major involved sites usually are the thoracic or cervical spine. The mechanisms of pathogenesis for the formation of an epidural mass during Hodgkin's disease are hematogenous dissemination from nodal sites or local infiltration of lymphomatous tissue. We document here a case of a 16 year-old boy who suffered from incomplete voiding due to dumbbell-shaped retroperitoneal Hodgkin's disease with cauda equina compression. He was successfully managed using surgery and adjuvant chemotherapy. Although lymphadenomatous tissue responds well to radiotherapy and chemotherapy, the role of surgery in this case was to achieve immediate nerve tissue decompression and to obtain an adequate specimen for pathological diagnosis. Magnetic resonance imaging (MRI) is a non-invasive and helpful tool when detecting spinal and paraspinal lesions and we emphasize that spinal MRI should be performed without delay if there is persistent back pain or sciatica.

    Melophagus ovinus (Linnaeus 1758), Hippobosca equina Linnaeus, 1758, and Hippobosca longipennis Fabricius, 1805 (Diptera: Hippoboscidae) are economically and medically important ectoparasites that can act as mechanic vectors of pathogens and cause myiasis in both human and domestic animals. As essential olfactory organs, antennae of these adult hippoboscids were examined using stereoscopic and scanning electron microscopes. General morphology of the antenna is provided in detail, combined with distribution, types, size, and ultrastructures of antennal sensilla. On the antennal funiculus, two types of sensilla are observed, including basiconic sensilla and coeloconic sensilla. Four common characters are shared among the three species: (1) the scape is either obsolete or fused with the fronto-clypeus; (2) branched antennal structures (branched pedicellar microtrichiae and branched arista with only one segment) are detected; (3) the enlarged antennal pedicel completely envelops the antennal funiculus; and (4) less types of sensilla on funiculus. Disparity and diversity of the antennal and sensory structures are analyzed from the phylogenetic and functional perspective. We suggest that hippoboscids are potential model for the study of the function of coeloconic sensilla in Calyptratae.

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

    Full Text Available Spinal epidural abscess is a severe, generally pyogenic, infection of the epidural space of spinal cord or cauda equina. The swelling caused by the abscess leads to compression or vascular disruption of neurological structures that requires urgent surgical decompression to avoid significant permanent disability. We share a rare case of Klebsiella pneumoniae spinal epidural abscess secondary to haematogenous spread of previous lung infection that presented late at our centre with cauda equina syndrome that showed good short-term outcome in delayed decompression. A 50-year old female presented with one-week history of persistent low back pain with progressively worsening bilateral lower limb weakness for seven days and urinary retention associated with saddle anesthesia of 2-day duration. Magnetic resonance imaging with contrast of the lumbo-sacral region showed an intramuscular collection of abscess at left gluteus maximus and left multifidus muscle with a L3-L5 posteriorly placed extradural lesion enhancing peripherally on contrast, suggestive of epidural abscess that compressed the cauda equina. The pus was drained using the posterior lumbar approach. Tissue and pus culture revealed Klebsiella pneumoniae, suggestive of bacterial infection. The patient made immediate improvement of muscle power over bilateral lower limbs postoperative followed by ability to control micturition and defecation in the 4th post-operative day. A good short-term outcome in delayed decompression of cauda equine syndrome is extremely rare. Aggressive surgical decompression combined with antibiotic therapy led to good short-term outcome in this patient despite delayed decompression of more than 48 hours.

    Optical spectroscopy of LuI 3 doped with Ce 3+ using ultraviolet and visible light excitation is reported. LuI 3 host excitation and emission and 4f-5d excitation and emission of Ce 3+ are observed. An empirical model based on crystal field splitting was used to estimate the energy of the highest 4f-5d excitation band. The crystal field splitting and centroid shift were compared to those of LuCl 3 :Ce 3+ and LuBr 3 :Ce 3+ . Temperature dependence of X-ray excited luminescence spectra shows thermal quenching, whereas that of the decay curve of Ce 3+ emission excited at the lowest 5d band of Ce 3+ does not indicate the presence of quenching of Ce 3+ emission for temperature below 625K. The quenching in LuI 3 :Ce 3+ therefore occurs before the 5d Ce 3+ emission takes place

  5. Fitogeografía de la Sierra Monte Grande, Charcas, San Luis Potosí, México

    Full Text Available Monte Grande is a small (41.8 km mountain range located at the southernmost part of the northern plateau of Mexico. It has a dry climate and its vegetation is characterized by pinyon woodland, oak scrub and three kinds of xerophytic scrub. Based on its flora of 397 species, we analyzed the historie phytogeography of Monte Grande, using only the taxa (families, genera and species that have a restricted distribution. At the family level, we identified three patterns of distribution: 1 from North America to northern South America; 2 mostly in the American continent; 3 families related to the Mediterranean region. At the genus level, five patterns were identified: 1 endemic of arid and semiarid lands of Mexico and adjacent regions of the United States; 2 from southern United States to Central America; 3 broadly distributed, but highly related to the Antillean region; 4 with Mediterranean relations; 5 disjunct or vicariant between the arid lands of North and South America. At the species level, nine patterns of distribution were identified: 1 septentrional plateau; 2 meridional plateau; 3 all plateaus and adjacent regions; 4 all plateaus-Sierra Madre de Oaxaca; 5 all plateaus-northwestern coast plain; 6 all plateaus-both coastal plains; 7 all plateaus-northeastern coastal plain; 8 Mexican xerophytic region; 9 all plateaus-both sierras Madre. These patterns are unlikely to be accidental, as they agree with recent theories about the process that led to the present landform configuration of the American Continent. On the basis of this interpretation, we postulate a major role of the Caribbean and the Former Mediterranean in the florigenesis of present linages of the arid and semiarid lands of Mexico.La sierra Monte Grande, con una extensión de 41.8 km, se localiza en el sur de la altiplanicie septentrional de México. Tiene un clima seco (8So y en ella prevalecen los matorrales xerófilos, piñonares y encinares. A partir de su flora, compuesta por 397 especies, se analizó su fitogeografía histórica con base en los taxones (familias, géneros y especies de distribución restringida. Al nivel de familia se identificaron tres patrones de distribución: 1 desde Norteamérica hasta el norte de Suramérica; 2 con mayor amplitud en el continente americano; 3 familias relacionadas con la región del Mediterráneo. Al nivel de género se encontraron cinco patrones: 1 endémicos de las zonas semisecas a muy secas de México y regiones adyacentes de Estados Unidos; 2 desde el sur de Estados Unidos hasta Centroamérica; 3 de distribución amplia pero con marcada relación antillana; 4 relacionados con la región del Mediterráneo; 5 disyuntos o vicariantes de las zonas áridas de Norte y Suramérica. Al nivel de especie se identificaron nueve patrones de distribución: 1 altiplanicie septentrional; 2 altiplanicie meridional; 3 altiplanicie y zonas adyacentes; 4 altiplanicie-Sierra Madre de Oaxaca; 5 altiplanicie-planicie costera noroccidental; 6 altiplanicie-planicies costeras noroccidental y nororiental; 7 altiplanicie-planicie costera nororiental; 8 región xerofítica mexicana; 9 altiplanicie sierras Madre. Se descarta que estos patrones sean casuales, pues concuerdan con teorías recientes sobre el proceso que culminó con la configuración actual del continente; se postula un papel destacado del Caribe en la florigénesis de linajes vegetales actuales de las zonas semisecas, secas y muy secas de México y en el mismo sentido un papel destacado del Mediterráneo Antiguo.

    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.

    Worldwide, Cervical Cancer (CC) is the fourth most common type of cancer and cause of death in women. It is a significant public health problem, especially in low and middle-income/Gross Domestic Product (GDP) countries. In the past decade, several studies of CC have been published, that identify the main modifiable and non-modifiable CC risk factors for Mexican women. However, there are no studies that attempt to explain the residual spatial variation in CC incidence In Mexico, i.e. spatial variation that cannot be ascribed to known, spatially varying risk factors. This paper uses a spatial statistical methodology that takes into account spatial variation in socio-economic factors and accessibility to health services, whilst allowing for residual, unexplained spatial variation in risk. To describe residual spatial variations in CC risk, we used generalised linear mixed models (GLMM) with both spatially structured and unstructured random effects, using a Bayesian approach to inference. The highest risk is concentrated in the southeast, where the Matlapa and Aquismón municipalities register excessive risk, with posterior probabilities greater than 0.8. The lack of coverage of Cervical Cancer-Screening Programme (CCSP) (RR 1.17, 95 % CI 1.12-1.22), Marginalisation Index (RR 1.05, 95 % CI 1.03-1.08), and lack of accessibility to health services (RR 1.01, 95 % CI 1.00-1.03) were significant covariates. There are substantial differences between municipalities, with high-risk areas mainly in low-resource areas lacking accessibility to health services for CC. Our results clearly indicate the presence of spatial patterns, and the relevance of the spatial analysis for public health intervention. Ignoring the spatial variability means to continue a public policy that does not tackle deficiencies in its national CCSP and to keep disadvantaging and disempowering Mexican women in regard to their health care.

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

    El 18 de Octubre pasado se cumplieron 30 años de la muerte del Profesor Luis López de Mesa, fecha luctuosa para la cultura americana. Con tal motivo quiero revivir su memoria y rendirle un cálido homenaje de gratitud y admiración, haciendo reminiscencias de hechos y anécdotas vividas gracias a la cordial amistad que me permitió apreciar la grandeza de su personalidad, que brilló con luz propia en todos los campos del saber humano, que lo llevó a escalar sitio de honor entre los grandes humanistas del continente.

    Sería un atrevimiento de mi parte, dada la poquedad de mis recursos literarios, intentar una biografía del profesor López de Mesa, tanto más, cuando eminentes autores han escrito obras magistrales relatando y exaltando las múltiples facetas de su excepcional cultura.

    Mi propósito es modesto: no he de referirme a su actuación como fundador del Colegio Máximo de las Academias Colombianas, ni de su hija “Bahía Solano”, ni del brillo con que desempeñó cargos tan importantes como Rector de la Universidad Nacional, Ministro de Educación Nacional y de Relaciones Exteriores, miembro de las más prestigiosas sociedades científicas y culturales, tanto nacionales como extranjeras, autor de numerosas obras a cual más eruditas, originales y profundas, y tantos títulos, cargos y actuaciones, que me sería largo enumerar.

    La sencillez y su modestia fueron admirables, como han sido las de los grandes genios. No conoció la vanidad ni el orgullo. Casi me atrevería a pensar que no se dio cuenta de su propia grandeza, a pesar de los múltiples y más variados elogios, honores y homenajes que le rendían tanto en el ambiente nacional como en el internacional, donde contaba con la admiración de los más brillantes exponentes de la cultura, que, distantes, se admiran recíprocamente, como de lejos se divisan y se contemplan las más elevadas cumbres de las monta

    The moisture sensitivity of LuI 3 :Ce,Hf and luminescent properties of undoped LuI 3 and LuI 3 :M (M=Ce 3+ , Tb 3+ , Dy 3+ ) powders were investigated. The possibility of improving the air and moisture stability of LuI 3 :Ce by Hf doping was tested. It was proven that the Hf contribution to the LuI 3 :Ce stability is very limited and is insignificant to render LuI 3 :Ce scintillator powders suitable for applications. Photoluminescence results of LuI 3 without dopants added on purpose showed luminescence due to a plurality of rare-earth elements' impurities. Two types of self-trapped luminescence were found. Energy transfer between host lattice, self-trapped excitons and rare-earth ions was investigated.

    Full Text Available This work reports a method for rapid amplification of the complete genome of equine influenza virus subtype 2 (H3N8. A ThermoScriptTM reverse transcriptase instead of the avian myeloblastosis virus reverse transcriptase or Moloney murine leukemia virus reverse transcriptase was used. This enzyme has demonstrated higher thermal stability and is described as suitable to make long cDNA with a complex secondary structure. The product obtained by this method can be cloned, used in later sequencing reactions or nested-PCR with the purpose of achieving a rapid diagnosis and characterization of the equine influenza virus type A. This detection assay might be a valuable tool for diagnosis and screening of field samples as well as for conducting molecular studies.En este trabajo comunicamos un método rápido que permite la amplificación del genoma completo del subtipo 2 (H3N8 del virus de la influenza equina. Se utilizó la enzima transcriptasa reversa ThermoScriptTM en lugar de la transcriptasa reversa del virus de la mieloblastosis aviar o la transcriptasa reversa del virus de la leucemia murina de Moloney. Esta enzima ha demostrado tener una alta estabilidad térmica y la capacidad de hacer largas copias de ADN con una estructura secundaria compleja. El producto obtenido por esta técnica puede ser clonado y utilizado posteriormente en reacciones de secuenciación o de PCR anidada con la finalidad de lograr un diagnóstico rápido y la caracterización del virus de la influenza equina tipo A. Este ensayo de detección puede llegar a ser una valiosa herramienta para el diagnóstico y el análisis de muestras de campo, así como para la realización de estudios moleculares.

    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)

    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.

    The extremely high scintillation efficiency of lutetium iodide doped by cerium is explained as a result of at least three factors controlling the energy transfer from the host matrix to activator. We propose and theoretically validate the possibility of a new channel of energy transfer to excitons and directly to cerium, namely the Auger process when Lu 4f hole relaxes to the valence band hole with simultaneous creation of additional exciton or excitation of cerium. This process should be efficient in LuI 3 , and inefficient in LuCl 3 . To justify this channel, we perform calculations of density of states using a periodic plane-wave density functional approach. The second factor is the increase of the efficiency of valence hole capture by cerium in the row LuCl 3 -LuBr 3 -LuI 3 . The third one is the increase of the efficiency of energy transfer from self-trapped excitons to cerium ions in the same row. The latter two factors are verified by cluster ab initio calculations. We estimate either the relaxation of these excitations and barriers for the diffusion of self-trapped holes (STH) and self-trapped exciton (STE). The performed estimations theoretically justify the high LuI 3 :Ce 3+ scintillator yield.

    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.

    Purpose: To assess motion of the spinal cord and cauda equina, which are critical neural tissues (CNT), which is important when evaluating the planning organ-at-risk margin required for stereotactic body radiation therapy. Methods and Materials: We analyzed CNT motion in 65 patients with spinal metastases (11 cervical, 39 thoracic, and 24 lumbar spinal segments) in the supine position using dynamic axial and sagittal magnetic resonance imaging (dMRI, 3T Verio, Siemens) over a 137-second interval. Motion was segregated according to physiologic cardiorespiratory oscillatory motion (characterized by the average root mean square deviation) and random bulk shifts associated with gross patient motion (characterized by the range). Displacement was evaluated in the anteroposterior (AP), lateral (LR), and superior-inferior (SI) directions by use of a correlation coefficient template matching algorithm, with quantification of random motion measure error over 3 separate trials. Statistical significance was defined according to P<.05. Results: In the AP, LR, and SI directions, significant oscillatory motion was observed in 39.2%, 35.1%, and 10.8% of spinal segments, respectively, and significant bulk motions in all cases. The median oscillatory CNT motions in the AP, LR, and SI directions were 0.16 mm, 0.17 mm, and 0.44 mm, respectively, and the maximal statistically significant oscillatory motions were 0.39 mm, 0.41 mm, and 0.77 mm, respectively. The median bulk displacements in the AP, LR, and SI directions were 0.51 mm, 0.59 mm, and 0.66 mm, and the maximal statistically significant displacements were 2.21 mm, 2.87 mm, and 3.90 mm, respectively. In the AP, LR, and SI directions, bulk displacements were greater than 1.5 mm in 5.4%, 9.0%, and 14.9% of spinal segments, respectively. No significant differences in axial motion were observed according to cord level or cauda equina. Conclusions: Oscillatory CNT motion was observed to be relatively minor. Our results

    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.

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

    The five sheets of the San Francisco folio the Tamalpais, Ban Francisco, Concord, Ban Mateo, and Haywards sheets map a territory lying between latitude 37° 30' and 38° and longitude 122° and 122° 45'. Large parts of four of these sheets cover the waters of the Bay of San Francisco or of the adjacent Pacific Ocean. (See fig. 1.) Within the area mapped are the cities of San Francisco, Oakland, Berkeley, Alameda, Ban Rafael, and San Mateo, and many smaller towns and villages. These cities, which have a population aggregating about 750,000, together form the largest and most important center of commercial and industrial activity on the west coast of the United States. The natural advantages afforded by a great harbor, where the railways from the east meet the ships from all ports of the world, have determined the site of a flourishing cosmopolitan, commercial city on the shores of San Francisco Bay. The bay is encircled by hilly and mountainous country diversified by fertile valley lands and divides the territory mapped into two rather contrasted parts, the western part being again divided by the Golden Gate. It will therefore be convenient to sketch the geographic features under four headings (1) the area east of San Francisco Bay; (2) the San Francisco Peninsula; (3) the Marin Peninsula; (4) San Francisco Bay.

  19. Cauda equina syndrome: is the current management of patients presenting to district general hospitals fit for purpose? A personal view based on a review of the literature and a medicolegal experience.

    Science.gov (United States)

    Todd, N V

    2015-10-01

    There is no universally agreed definition of cauda equina syndrome (CES). Clinical signs of CES including direct rectal examination (DRE) do not reliably correlate with cauda equina (CE) compression on MRI. Clinical assessment only becomes reliable if there are symptoms/signs of late, often irreversible, CES. The only reliable way of including or excluding CES is to perform MRI on all patients with suspected CES. If the diagnosis is being considered, MRI should ideally be performed locally in the District General Hospitals within one hour of the question being raised irrespective of the hour or the day. Patients with symptoms and signs of CES and MRI confirmed CE compression should be referred to the local spinal service for emergency surgery. CES can be subdivided by the degree of neurological deficit (bilateral radiculopathy, incomplete CES or CES with retention of urine) and also by time to surgical treatment (12, 24, 48 or 72 hour). There is increasing understanding that damage to the cauda equina nerve roots occurs in a continuous and progressive fashion which implies that there are no safe time or deficit thresholds. Neurological deterioration can occur rapidly and is often associated with longterm poor outcomes.

    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.

    Felix Kurt Ernst Schmelzer

    2016-11-01

    Full Text Available From the 15th century on, the practitioners of the mechanical arts obtain a new self-confidence and do no longer want to be regarded merely as manual workers. In this context, they frequently underline the mathematical basis of their discipline in order to increase its value from the status of a mechanical to that of a liberal art. In the Spanish golden age period, the military art, amongst others, is conceived as a mathematical discipline. A particularly curious case is the Libro de las grandezas de la espada (1600 whose author, Luis Pacheco de Narváez (1570-1640, propagates the art of swordsmanship, which he names «the true skill», as a science based on the disciplines of the quadrivium. The present article outlines the arguments applied by Pacheco in a preliminary chapter in order to prove the mathematical and scientific status of his discipline.

    Colombian physician Luis Benigno Patiño Camargo was one of the pioneers in the study of rickettsioses in South America, demonstrating for the first time in Colombia the presence of Rickettsia rickettsii as the etiological agent of a highly deadly exanthematic febrile syndrome in the 1930s. 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

  1. Situação epidemiológica da anemia infecciosa equina em equídeos de tração do Distrito Federal

    Full Text Available RESUMO: A anemia infecciosa equina (AIE é uma doença causada por um lentivirus que possui distribuição mundial. Essa enfermidade é um entrave ao desenvolvimento da equinocultura no Brasil devido à obrigatoriedade de eutanásia dos animais positivos. Este trabalho teve como objetivo estimar a prevalência de AIE em equídeos de tração no Distrito Federal, assim como identificar fatores de risco associados à doença. Foram sorteados aleatoriamente 350 proprietários (Unidades Primárias de Amostragem- UPA e foram amostrados todos os equídeos (Unidades secundárias de Amostragem de cada proprietário sorteado, totalizando 496 animais. As amostras sanguíneas foram analisadas no Lanagro/MG por meio da técnica de imunodifusão em ágar gel (IDGA. No momento da coleta de sangue, também foi aplicado um questionário epidemiológico para a análise de possíveis fatores de risco. A prevalência de AIE nas UPA foi estimada em 2,29%, (IC 95%: 1,01-4,2% e nos animais foi de 1,81% (IC 95%: 0,55-3,07%. A prevalência foi significativamente maior em muares do que em equinos. Não foi possível comprovar a presença de nenhum outro fator de risco associado à doença. Este estudo demonstra que a prevalência da AIE em equídeos de tração é baixa no Distrito Federal, porém mais alta do que os dados de vigilância de rotina sugerem, o que justifica a eutanásia dos equídeos reagentes, com a finalidade de promover a erradicação da enfermidade. Ratifica-se a importância da realização de exames periódicos nesses animais e a manutenção das atividades de vigilância.

    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.

    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.

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.

    International Nuclear Information System (INIS)

    Posner, D.M.

    1988-01-01

    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

    The complementary investigation techniques, Moessbauer spectroscopy, transmission electron microscopy with selected area electron diffraction (TEM/SAED), X-ray diffraction (XRD) have been used to investigate the fate of the Valea lui Stan, Romania, gold-ore nanoscale-minerals during the long time of residence in the waste dumps. The preliminary investigations showed such waste dumps to contain significant amount of metals which cannot be identified by conventional methods. An intense research activity started up in order to evaluate the possibilities to recycle Valea lui Stan waste dumps and to recover metals by chemical or phytoextraction procedures. The waste dumps naturally show different mineral constituents with clay minerals as major phases, observed by XRD-technique. Although the waste dumps materials have whitish-yellowish colours, MOeSSBAUER technique evidences the presence of the finely dispersed iron bearing minerals. The authors are focusing to inspect and analyze Fe-compounds in the samples collected from Valea lui Stan's waste dumps in order to identify the magnetic phases by Moessbauer technique.

    2006-01-01

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

  20. Analysis of José Luis Rodríguez Zapatero’s nonverbal communication

    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.

  1. 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.

    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 es una aproximación crítica a las crónicas del autor mexicano Luis G. Urbina; investigación que encontró su origen en la importancia de la crónica modernista como espacio creativo y reflexivo cuyas características y alcances aún hoy generan un sinnúmero de trabajos críticos. Tanto José Martí como Manuel Gutiérrez Nájera y otros de los autores emblemáticos del modernismo, han sido escrutados y valorados a lo largo de estos años. Sin embargo, Urbina ha permanecido relegado a las historias de la literatura y a las bibliotecas, lo cual sugiere un casi nulo conocimiento de su obra. En este ensayo se analizan algunos de los textos incluidos en su libro Cuentos vividos y crónicas soñadas, publicado en 1915, para contribuir a la revalorización y difusión de su obra a 150 años de su nacimiento.

    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.

    To assess the incidence of acute Rheumatic Fever (ARF). A retrospective, descriptive, observational study on the first attack and recurrence was performed in a general hospital and a reference center. By Jones criteria: 67 cases, 39 women and 28 men; 58% first attack, 42% recurrence. Higher incidence during spring-winter. The most common major criteria were: carditis, polyarthritis. The most common minor criteria were: fever, arthralgias and acute phase reaction markers. No differences between hospitals were noted. Evidence of contact with streptococcus was found. Mitral, aortic and tricuspid valves were commonly affected. Incidence in the age group > 5 < 20 was 7/1000. Incidence of ARF has decreased, but has not been eradicated. It occurs in developing countries, where it remains an issue of public health. Failures in clinical suspicion, prophylaxis, and adherence to treatment influence this situation. Education for health, early diagnosis, and primary and secondary prophylaxis should be reinforced.

    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 2 and LiF TLD-100 were exposed at 14 points along the mine tunnels in order to estimate the mean 222 Rn concentration and the ambient dose equivalent during the summer season (November 2008 to February 2009). The values for the 222 Rn concentration at each monitoring site ranged from 1.8 ± 0.1 kBq m -3 to 6.0 ± 0.5 kBq m -3 , with a mean value of 4.8 kBq m -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 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.

    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

  11. Reading the Other Side of the Story: Ominous Voice and the Sociocultural and Political Implications of Luis Spota's Murieron a mitad del río

    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

    Full Text Available In the historical, turbulent and exciting times of the Renaissance Humanism, characterized by a return to classic Antiquity, and the renovation of all cultural manifestations, both philosophy and religion are affected from their very foundations. This scholastic crisis affects in such a way the conscience, of the individuals and the people that it demands a solution immediate although provisional solution, so that we continuing even the business of living. No wonder that among the ruins of tomist morality, some moralists arise, as that of Justus Lipsius (1547-1606, engased in renovating the stoic doctrines of Epicteto (ca. 50 to. of C. -125/138 and Séneca (ca. 4-65, and that of Pierre Gassendi (1592-1655, determined to Christianize Epicuro. For some could be a summarise of the Ethics of the Renaissance others believe that the first Ethics of modern philosophy should be considered to be a product of the Renaissance, even if it does not belong chronologically to it they meam Descartes (1596-1650, Spinoza (1632-1677 and Kant (1724-1804. However according to the opinion of some significant authors, we dont need to go back to Kant to find the authentic Ethics of the Renaissance. Juan Luis Vives published in 1524 a small booklet titled Introductio ad Sapientiam that for its internal ideological structure and its origin senequista and christan leaning occupies a privileged place within modern Ethic, and if we take accourt his content and chronology it can be considered as the Ethics of the Renaissance, at least of the Spanish Renaissance.

    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.

Contudo, isolados ambientais demonstraram níveis elevados de resistência à penicilina e cloranfenicol. Da mesma forma, os isolados humanos apresentaram alto nível de resistência ao ceftiofur, lincomicina e sulfazotrim. O IRMA em todos os isolados de R. equi variou de 0 a 0,67, tendo como valores médios 0,19 para as amostras clínicas de equinos, 0,14 nas ambientais e em isolados humanos foi de 0,1. Apesar da alta sensibilidade observada nos isolados analisados, verificaram-se diferentes níveis de resistência nas amostras clínicas de equinos. Em contraste, os isolados ambientais não demonstraram resistência em relação aos agentes antimicrobianos utilizados na terapia da rodococose equina. Além disso, em isolados humanos não se observou resistência contra a droga para uso restrito em terapia de humano. Com base no IRMA observado em isolados clínicos de equinos, destacamos a importância de medidas restritivas e mais cautela na utilização de antimicrobianos em infecções causadas por R. equi para evitar o aumento de novas cepas multirresistentes.

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

    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

    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.

    Full Text Available 1915 is considered a decisive year in world history. Underneath wartime plundering, eighteenth-century beliefs in social progress and human civilization collapsed, and other political and philosophical credos sprouted, while aesthetic avant-gardes created new forms of artistic and literary expression. That same year, from his exile in Madrid, Martín Luis Guzmán would define the coordinates that would guide his life, while trying to assimilate his recent experiences during the Mexican Revolution and make way as a writer, under the immediate protection of Alfonso Reyes and the far-away but determining one of Pedro Henríquez Ureña. Without abandoning his political vocation and remaining open to new trends, Guzmán drew up his own path, which would lead him alongside his mentors and to the forefront of literature in Spanish.

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.

    The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data...

    Seventy-two gravity cores were collected by the U.S. Geological Survey in 1990, 1991, and 2000 from San Pablo Bay and Carquinez Strait, California. The gravity cores collected within San Pablo Bay contain bioturbated laminated silts and sandy clays, whole and broken bivalve shells (mostly mussels), fossil tube structures, and fine-grained plant or wood fragments. Gravity cores from the channel wall of Carquinez Strait east of San Pablo Bay consist of sand and clay layers, whole and broken bivalve shells (less than in San Pablo Bay), trace fossil tubes, and minute fragments of plant material.
