    Full Text Available Mammal fossil remains from San Pedro (Buenos Aires Province, Argentina are very poorly known. In this paper, best preserved specimens of Equidae and Gomphotheriidae are described. They come from “Campo Spósito” quarry near San Pedro city. The quarry was referred to Lujanian Age, Biozone of Equus (Amerhippus neogeus. We conducted a comparative study with other South American horse and gomphothere remains, mainly from Argentina and Brazil, allow their identification as Equus (Amerhippus neogeus, Hippidion principale and Stegomastodon cf. S. platensis. Two absolute dates were obtained by the method of OSL: 37626±4198 y 41554±3756 years BP. Based on this data and correlation with other localities we referred this bed to oxygen isotopic stage 3.

    Full Text Available Durante el siglo XVIII, se multiplicó la presencia de “pueblos de espa-ñoles” y villas en la frontera sur hispanoamericana. El protagonismo de ocupantes rurales en la formación de “pueblos de españoles” fue más frecuente en la campaña de Buenos Aires que en otras jurisdicciones, aunque poco se conoce sobre su proceder. El objetivo del artículo fue analizar las características de los ocupantes rurales y el rango de acción que tuvieron para solicitar el reconocimiento legal de terrenos para la formación de un pueblo en la campaña de Buenos Aires durante el siglo XVIII y parte del XIX. El análisis del caso del pueblo de San Pedro nos permitió profundizar la situación de los “ocupantes” y abrir varios inte-rrogantes sobre la regulación de los derechos por la tierra, particularmen-te sobre los pueblos y villas, en un período que suele estar vinculado a transformaciones en los derechos y en las relaciones de poder ejercidas en su puesta en práctica.

    The Telescopio San Pedro Martir (TSPM) is a new ground-based optical telescope project, with a 6.5 meters honeycomb primary mirror, to be built in the Observatorio Astronomico Nacional on the Sierra San Pedro Martir (OAN-SPM) located in Baja California, Mexico. The OAN-SPM has an altitude of 2830 meters above sea level; it is among the best location for astronomical observation in the world. It is located 1830 m higher than the atmospheric inversion layer with 70% of photometric nights, 80% of spectroscopic nights and a sky brightness up to 22 mag/arcsec2. The TSPM will be suitable for general science projects intended to improve the knowledge of the universe established on the Official Mexican Program for Science, Technology and Innovation 2014-2018. The telescope efforts are headed by two Mexican institutions in name of the Mexican astronomical community: the Universidad Nacional Autonoma de Mexico and the Instituto Nacional de Astrofisica, Optica y Electronica. The telescope has been financially supported mainly by the Consejo Nacional de Ciencia y Tecnologia (CONACYT). It is under development by Mexican scientists and engineers from the Center for Engineering and Industrial Development. This development is supported by a Mexican-American scientific cooperation, through a partnership with the University of Arizona (UA), and the Smithsonian Astrophysical Observatory (SAO). M3 Engineering and Technology Corporation in charge of enclosure and building design. The TSPM will be designed to allow flexibility and possible upgrades in order to maximize resources. Its optical and mechanical designs are based upon those of the Magellan and MMT telescopes. The TSPM primary mirror and its cell will be provided by the INAOE and UA. The telescope will be optimized from the near ultraviolet to the near infrared wavelength range (0.35-2.5 m), but will allow observations up to 26μm. The TSPM will initially offer a f/5 Cassegrain focal station. Later, four folded Cassegrain and

    Full Text Available A nivel mundial el uso del agua para riego representa 70 % de la demanda hídrica total, con una eficiencia de uso inferior al 40 %. Para lograr un uso sustentable del recurso hídrico es necesaria una adecuada planificación y un aumento en la eficiencia del uso. La producción de materia seca de un cultivo depende entre otros factores del agua transpirada. El conocimiento de la evapotranspiración es la base para el cálculo de las necesidades de riego, por lo tanto resulta una herramienta imprescindible para el uso sustentable del recurso. El fenómeno de "El Niño - Oscilación del Sur" (ENOS es uno de los principales responsables de la variabilidad climática interanual, tiene influencia sobre la región pampeana argentina, y su ocurrencia puede ser pronosticada con meses de anticipación. El objetivo de este trabajo fue analizar el impacto del ENOS sobre las variaciones mensuales de la evapotranspiración de la localidad de San Pedro, para el periodo 2005-2011. Los resultados indicaron que los desvíos de la evapotranspiración con respecto al valor histórico del periodo 1969-2004 son negativos durante eventos "El Niño" y positivos durante "La Niña". Las variaciones de la evapotranspiración de los meses de diciembre y febrero tuvieron una correlación altamente significativa con los eventos del fenómeno ENOS. En estos meses el ENOS resultaría un buen predictor de las variaciones de la evapotranspiración y por ende de los volúmenes de agua necesarios para satisfacer la demanda de los cultivos.

    2015-08-01

    The San Pedro River in Southeastern Arizona is home to nearly 45% of the 900 total species of birds in the United States; millions of songbirds migrate though this unique flyway every year. As the last undammed river in the Southwest, it has been called one of the “last great places” in the US. Human activity has had striking and highly visible impacts on the San Pedro River. As a result, and to help preserve and conserve the area, much of the region has been designated the San Pedro Riparian National Conservation Area (SPRNCA). Attention has been directed to impacts of population, water depletion, and border fence barriers on the riparian environment. To date, there has been little recognition that light at night (LAN), evolving with the increased local population, could have moderating influences on the area. STEM Laboratory has pioneered techniques of coordinated airborne and ground based measurements of light at night, and has undertaken a program of characterizing LAN in this region. We conducted the first aerial baseline surveys of sky brightness in 2012. Geographic Information Systems (GIS) shapefiles allow comparison and correlation of various biological databases with the LAN data. The goal is to better understand how increased dissemination of night time lighting impacts the distributions, behavior, and life cycles of biota on this ecosystem. We discuss the baseline measurements, current data collection programs, and some of the implications for specific biological systems.

    A preliminary report on the fossil vertebrates of the San Pedro Valley, Ariz., collected by Kirk Bryan and me in the winter of 1920 and 1921 was published in 1922. This report includes a brief statement regarding the geology of the locality and a preliminary list of fossil vertebrates obtained by the expedition of 1921, with descriptions of the rodents and rabbits. Two additional papers on this interesting fauna have also appeared, one on the turtles by C.W. Gilmore and one on the birds by Alexander Wetmore. The present contribution deals with the proboscideans and edentates and gives a somewhat fuller discussion of the geology of the fossil-bearing beds.

    We present optical UBVRI zenith night sky brightness measurements collected on 18 nights during 2013 to 2016 and SQM measurements obtained daily over 20 months during 2014 to 2016 at the Observatorio Astronómico Nacional on the Sierra San Pedro Mártir (OAN-SPM) in México. The UBVRI data is based upon CCD images obtained with the 0.84 m and 2.12 m telescopes, while the SQM data is obtained with a high-sensitivity, low-cost photometer. The typical moonless night sky brightness at zenith averaged over the whole period is U = 22.68, B = 23.10, V = 21.84, R = 21.04, I = 19.36, and SQM = 21.88 {mag} {{arcsec}}-2, once corrected for zodiacal light. We find no seasonal variation of the night sky brightness measured with the SQM. The typical night sky brightness values found at OAN-SPM are similar to those reported for other astronomical dark sites at a similar phase of the solar cycle. We find a trend of decreasing night sky brightness with decreasing solar activity during period of the observations. This trend implies that the sky has become darker by Δ U = 0.7, Δ B = 0.5, Δ V = 0.3, Δ R=0.5 mag arcsec‑2 since early 2014 due to the present solar cycle.

    This article describes the study carried out on a series of oil paintings on canvas from the eighteenth century that were restored at Centro de Produccion e Investigacion en Restauracion y Conservacion Artistica y Bibliografica - Tarea (CEIRCAB-Tarea), Buenos Aires, Argentina: the San Pedro Gonzalez Telmo Sibyls. Experimental study was undertaken to identify inorganic pigments and the technique used in their confection; and, in this way, try to add information about their local origin. Therefore special emphasis was put to infer technologies used in the manufacturing of these paintings. Elemental analysis was performed by total reflection X-ray fluorescence spectrometry (TXRF) and complemented by optical and polarized light microscopy. Microsampling was carefully done over areas of the paintings which were damaged and where a small additional loss will not be noticed. This investigation has shown that a variety of pigments were used, namely earth pigments (red and yellow ochres), white lead, vermilion, etc., and they were used either pure or in mixtures. This characterization helped conservators in their decisions regarding a better understanding of the deterioration processes. In addition, this research about the material composition allowed the art historians and restorers the possibility to obtain information about where, when or by whom The San Pedro Gonzalez Telmo Sibyls may have been painted.

    A quantitative study of toxicity levels of the San Pedro River and its main tributaries around the city of Aguascalientes, Mexico was conducted. Our study determined individual CL(50) values for each sampling point at 3 different times of the year corresponding to the main seasons of the year in terms of the hydrological cycle (dry, low rain and high rain season). Those LC(50) values were used to calculate the acute. Toxicity Units (aTU) that allowed us to compare levels of toxicity along the San Pedro River and two of its main tributaries. The sample that showed highest toxicity was IPIVA. This is due to the large quantity of industrial discharges that receives. Its effluent was responsible for the largest contribution of toxicity to the San Pedro River over the three rounds of sampling of this study. Our study classified an important portion of the San Pedro River and two of its main tributaries in toxic, moderately toxic and lightly toxic. No portion of the river studied was free of toxicity, either acute or sublethal. This study demonstrated that in spite of the operation of several water treatment plants along the San Pedro River, for the most part, the water quality of the river is still unacceptable.

    2002-01-01

    The last decade of the eighteenth century may be described as a "golden age" in the history of the Hospital of San Pedro of Puebla. Under the stewardship of its director, Father Ignacio Domenech, San Pedro underwent an extensive renovation of its physical plant and a thorough administrative reorganization that turned it into one of the best medical care and research institutions in New Spain. The article draws a profile of the patients who filled the hospital's wards and adds a human dimension to the many names and ailments listed in the registries. It also describes the valiant efforts of the medical staff who daily shared the patients' struggle against illness. Fighting immense odds, the practitioners sought to provide good-quality care and to further their limited understanding of disease. A detailed analysis of San Pedro's everyday life reveals a portrait of human suffering, professional dedication, and humanity's pursuit of knowledge.

    This study assessed progress toward achieving sustainable groundwater use in the Sierra Vista Subwatershed of the Upper San Pedro Basin, Arizona, through evaluation of 14 indicators of sustainable use. Sustainable use of groundwater in the Sierra Vista Subwatershed requires, at a minimum, a stable rate of groundwater discharge to, and thus base flow in, the San Pedro River. Many of the 14 indicators are therefore related to long-term or short-term effects on base flow and provide us with a means to evaluate groundwater discharge to and base flow in the San Pedro River. The indicators were based primarily on 10 to 20 years of data monitoring in the subwatershed, ending in 2012, and included subwatershedwide indicators, riparian-system indicators, San Pedro River indicators, and springs indicators.

    It has been proposed that the global circulation of the atmosphere winds at 200 mb can be used as a criteria to establish the suitability of a site for the development of adaptive optics techniques such as slow wavefront corrugation correction. By using the NOAA NCEP/NCAR Reanalysis data base we analyze the monthly average wind velocity at 200 mb for a 16 year period, for two sites in Mexico: Sierra Negra and San Pedro M\\'artir. We compare the results with those obtained for Mauna Kea, Paranal and La Silla, with Maidanak in Uzbekistan, and with Gamsberg in Namibia. We show that for all the sites under study there is a yearly wind speed modulation and we model that modulation. Our results show that Sierra Negra and San Pedro M\\'artir are comparable with the best observatory sites as Mauna Kea and are amongst the most advantageous sites to apply adaptive optics techniques.

  1. Quaternary Geochronology, Paleontology, and Archaeology of the Upper San Pedro River Valley, Sonora, Mexico

    Gaines, E. P.

    2013-12-01

    This poster presents the results of multi-disciplinary investigations of the preservation and extent of Quaternary fossil-bearing strata in the San Pedro River Valley in Sonora, Mexico. Geologic deposits in the portions of the San Pedro Valley in southern Arizona contain one of the best late Cenozoic fossil records known in North America and the best record of early humans and extinct mammals on the continent. The basin in the U.S. is one of the type locations for the Blancan Land Mammal Age. Hemiphilian and Irvingtonian fossils are common. Rancholabrean remains are widespread. Strata in the valley adjacent to the international border with Mexico have yielded the densest concentration of archaeological mammoth-kill sites known in the western hemisphere. Despite more than 60 years of research in the U.S., however, and the fact that over one third of the San Pedro River lies south of the international boundary, little has been known about the late Cenozoic geology of the valley in Mexico. The study reported here utilized extensive field survey, archaeological documentation, paleontological excavations, stratigraphic mapping and alluvial geochronology to determine the nature and extent of Quaternary fossil-bearing deposits in the portions of the San Pedro Valley in Sonora, Mexico. The results demonstrate that the Plio-Pleistocene fossil -bearing formations known from the valley in Arizona extend into the uppermost reaches of the valley in Mexico. Several new fossil sites were discovered that yielded the remains of Camelids, Equus, Mammuthus, and other Proboscidean species. Late Pleistocene archaeological remains were found on the surface of the surrounding uplands. AMS radiocarbon dating demonstrates the widespread preservation of middle- to late- Holocene deposits. However, the late Pleistocene deposits that contain the archaeological mammoth-kill sites in Arizona are absent in the valley in Mexico, and are now known to be restricted to relatively small portions of

    Full Text Available Agricultural societies in the state of Mexico involved a form of legal resistance used by indigenous communities in the face of liberal individualization policies of communal property, particularly the federal seizure law of June 25, 1956. In this context, some residents of the towns of Santa Cruz and San Miguel created an agricultural association, as did residents from the town of San Pedro, to retain the collective use of their communal goods and acquire some legal capacity. This condition thus allowed indigenous peoples to present writs of amparo to defend "private" rights.

  5. Oral health in prehistoric San Pedro de Atacama oases, Northern Chile.

    2015-12-01

    After almost 2000 years of local development, including limited trading with neighboring ethnic groups, the societies that occupied the oases of San Pedro de Atacama, Northern Chile, became part of the trade web of the Tiwanaku empire, between 500 and 1000 CE. Archaeological evidence tends to support the idea that the period under the influence of the altiplano (high plane) empire was very affluent. Here we investigate the possibility that this affluence had a positive impact on the health status of the Atacameneans, using the oral health as an indirect indicator of quality of life. Dental decay, dental abscess, dental wear, linear enamel hypoplasia, periodontal disease and dental calculus were analyzed on 371 skeletons from 12 sites from San Pedro de Atacama oases. We believe that if, indeed, there were better biological conditions during the altiplano influence, this could have been caused by the access to a more diversified food intake promoted by the intensification of the trading network established by Tiwanaku in the central-south Andes, of which San Pedro de Atacama became an important node.

    A large body of research exists that identifies and values ecosystem services - the benefits that ecosystems provide to humans (MA, 2005) - and their underlying ecological processes. However, the development of software decision support tools that integrate ecology, economics and geography that can be independently used within the public, private, academic and NGO sectors is a more recent phenomenon (Ruhl et al., 2007; Daily et al., 2009). Spurred by growing demand for more sophisticated analysis of the social and economic consequences of land management decisions, the US Department of Interior - Bureau of Land Management (BLM) launched a pilot project with the US Geological Survey (USGS) to assess the usefulness and feasibility of ecosystem service assessment and valuation tools to provide inputs to decision-making. The project analysed ecosystem services in the US portion of the San Pedro River watershed, which includes the BLM-managed San Pedro Riparian National Conservation Area (SPRNCA), to improve the understanding of complex social and ecological relationships that transcend administrative divisions. The BLM manages some 99 million hectares, primarily in the western United States, and 283 million hectares of sub-surface mineral estate. BLM's multiple-use mission requires that it appropriately balance non-extractive uses such as habitat conservation, recreation and archaeological heritage protection and the extractive use of resources such as timber, oil and gas, coal, uranium, and other minerals.

    2011-01-01

    San Pedro M\\'artir in the Northwest of Mexico is the site of the Observatorio Astron\\'omico Nacional. It was one of the five candidates sites for the Thirty Meter Telescope, whose site-testing team spent four years measuring the atmospheric properties on site with a very complete array of instrumentation. Using the public database created by this team, we apply a novel method to solar radiation data to estimate the daytime fraction of time when the sky is clear of clouds. We analyse the diurnal, seasonal and annual cycles of cloud cover. We find that 82.4 per cent of the time the sky is clear of clouds. Our results are consistent with those obtained by other authors, using different methods, adding support to this value and proving the potential of the applied method. The clear conditions at the site are particularly good showing that San Pedro M\\'artir is an excellent site for optical and infrared observations.

    This paper describes lake sediment spheroidal carbonaceous particle (SCP) profiles from Laguna Chica San Pedro, located in the Biobio Region, Chile (36{sup o} 51' S, 73{sup o} 05' W). The earliest presence of SCPs was found at 16 cm depth, corresponding to the 1915-1937 period, at the very onset of industrial activities in the study area. No SCPs were found at lower depths. SCP concentrations in Laguna Chica San Pedro lake sediments were directly related to local industrial activities. Moreover, no SCPs were found in Galletue lake (38{sup o} 41' S, 71{sup o} 17.5' W), a pristine high mountain water body used here as a reference site, suggesting that contribution from long distance atmospheric transport could be neglected, unlike published data from remote Northern Hemisphere lakes. These results are the first SCP sediment profiles from Chile, showing a direct relationship with fossil fuel consumption in the region. Cores were dated using the {sup 21}Pb technique. - The lake sediment record of SCPs shows the record of fossil-fuel derived pollution in Central Chile.

    San Pedro Mártir in the north-west of Mexico is the site of the Observatorio Astronómico Nacional. It was one of the five candidate sites for the Thirty Meter Telescope, whose site-testing team spent four years measuring the atmospheric properties on site with a very complete array of instrumentation. Using the public data base created by this team, we apply a novel method to solar radiation data to estimate the daytime fraction of time when the sky is clear of clouds. We analyse the diurnal, seasonal and annual cycles of cloud cover. We find that 82.4 per cent of the time the sky is clear of clouds. Our results are consistent with those obtained by other authors, using different methods, adding support to this value and proving the potential of the applied method. The clear conditions at the site are particularly good showing that San Pedro Mártir is an excellent site for optical and infrared observations.

    We describe the recent upgrade of the Manchester Echelle Spectrometer, currently in use at San Pedro Mártir. This upgrade has included a user interface and a new CCD acquisition software. The spectrometer control is now done by a microcontroller, whose inputs are new sensors and encoders installed inside the spectrometer. The instrument control is now fully carried out from a graphical user interface running in a personal computer. The acquisition computer sends the images to the GUI through an ethernet link. In this paper, we present the general scheme and the programs developed for Linux (in C++ and Tcl/Tk) that permits an easy integral operation of the instrument, as well as the creation of scripts intended to the optimization of the observing run and the future interaction with the telescope and the guider. This upgraded system has been operated successfully during several campaigns in the 2.1-meter telescope at Observatorio Astronómico Nacional in San Pedro Mártir.

  14. Transient electromagnetic study of basin fill sediments in the Upper San Pedro Basin, Mexico

    Science.gov (United States)

    Bultman, M.W.; Gray, F.

    2011-01-01

    The Upper San Pedro River Basin in Mexico and the United States is an important riparian corridor that is coming under increasing pressure from growing populations and the associated increase in groundwater withdrawal. Several studies have produced three-dimensional maps of the basin fill sediments in the US portion of the basin but little work has been done in the Mexican portion of the basin. Here, the results of a ground-based transient electromagnetic (TEM) survey in the Upper San Pedro Basin, Mexico are presented. These basin fill sediments are characterized by a 10-40 m deep unsaturated surficial zone which is composed primarily of sands and gravels. In the central portion of the basin this unsaturated zone is usually underlain by a shallow clay layer 20-50 m thick. Beneath this may be more clay, as is usually the case near the San Pedro River, or interbedded sand, silt, and clay to a depth of 200-250 m. As you move away from the river, the upper clay layer disappears and the amount of sand in the sediments increases. At 1-2 km away from the river, sands can occupy up to 50% of the upper 200-250 m of the sediment fill. Below this, clays are always present except where bedrock highs are observed. This lower clay layer begins at a depth of about 200 m in the central portion of the basin (250 m or more at distances greater than 1-2 km from the river) and extends to the bottom of most profiles to depths of 400 m. While the depth of the top of this lower clay layer is probably accurate, its thickness observed in the models may be overestimated due to the relatively low magnetic moment of the TEM system used in this study. The inversion routine used for interpretation is based on a one-dimensional geologic model. This is a layer based model that is isotropic in both the x and y directions. Several survey soundings did not meet this requirement which invalidates the inversion process and the resulting interpretation at these locations. The results from these

    The San Pedro M\\'artir kinematic catalogue of galactic planetary nebulae provides spatially resolved, long-slit Echelle spectra for about 600 planetary nebulae. The data are presented wavelength calibrated and corrected for heliocentric motion. For most objects multiple spectra have been acquired and images with accurate slit positions on the nebulae are also presented for each object. This is the most extensive and homogeneous single source of data concerning the internal kinematics of the ionized nebular material in planetary nebulae. Data can be retrieved for individual objects or selected by groups that share some common characteristics, such as by morphological classes, galactic population, binary cores, presence of fast outflows, etc. The catalogue is available through the world wide web at http://kincatpn.astrosen.unam.mx .

    We conducted an 18 month long study of the weather conditions of the Vallecitos, a proposed site in Mexico to harbor the northern array of the Cherenkov Telescope Array (CTA). It is located in Sierra de San Pedro Martir (SPM) a few kilometers away from Observatorio Astron\\'omico Nacional. The study is based on data collected by the ATMOSCOPE, a multi-sensor instrument measuring the weather and sky conditions, which was commissioned and built by the CTA Consortium. Additionally, we compare the weather conditions of the optical observatory at SPM to the Vallecitos regarding temperature, humidity, and wind distributions. It appears that the excellent conditions at the optical observatory benefit from the presence of microclimate established in the Vallecitos.

    High-precision 40Ar/39Ar geochronology coupled with GIS spatial analysis provides constraints on magma eruption rates over the past 1 Myr of the Ceboruco-San Pedro volcanic field (1870 km2), located in the Tepic-Zacoalco rift in western Mexico. The volcanic field is part of the Trans Mexican Volcanic arc and is dominated by the andesitic-dacitic stratocone of Volcan Ceboruco and includes peripheral fissure-fed flows, domes, and monogenetic cinder cones. The ages of these volcanic features were determined using 40Ar/39Ar laser step-heating techniques on groundmass or mineral separates, with 78% of the 52 analyses yielding plateau ages with a 2 sigma error < 50 kyrs. The volumes were determined using high resolution (1:50,000) digital elevation models, orthophotos, and GIS software, which allowed for the delineation of individual volcanic features, reconstruction of the pre-eruptive topography, and volume calculations by linear interpolation. The relative proportions of the 80 km3 erupted over the past 1 Myr are 14.5% basaltic andesite, 64.5% andesite, 20% dacite, and 1% rhyolite, demonstrating the dominance of intermediate magma types (in terms of silica content). Overall, there appears to be no systematic progression in the eruption of different magma types (e.g., basalt, andesite, dacite, etc.) with time. However, more than 75% of the total volume of lava within the Ceboruco-San Pedro volcanic field erupted in the last 100 kyrs. This reflects the youthfulness of Volcan Ceboruco, which was constructed during the last 50 kyrs and has a present day volume of 50 +/- 2.5 km3, accounting for 81% of the andesite and 50% of the dacite within the volcanic field. Eleven cinder cones, ranging from the Holocene to 0.37 Ma, display a narrow compositional range, with 52-58 wt% SiO2, 3-5.5 wt% MgO, and relatively high TiO2 concentrations (0.9-1.8 wt%). The total volume of the cinder cones is 0.83 km3. No lavas with < 51 wt% SiO2 have erupted in the past 1 Myr. Peripheral

San Pedro de Atacama, for example, is a small town where earth blocks (adobes and rammed earth (tapial are important ways to construct, an art passed on through generations. Energy properties of earth are very interesting: thermal conductivity is low; heat storage capacity is high; color is variable and can be used to absorb or to reject solar radiation. However, nowadays the government social dwelling service is proposing a different type of construction, which does not maintain any relation with the tradition. This paper presents simulation studies and monitoring of four different San Pedro houses, constructed by using different techniques and materials. Results can be used to discuss the thermal performance needed in desert climate and the reliability of social dwelling service houses, under construction at this time in the town.

    Telescopio San Pedro Mártir (TSPM) project intends to build a 6.5 meters telescope with alt-azimuth design, currently at the conceptual design. The project is an association between Instituto de Astronomía de la Universidad Nacional Autónoma de México (IA-UNAM) and the Instituto Nacional de Astrofísica, Óptica Electrónica (INAOE) in partnership with department of Astronomy and Steward Observatory of University of Arizona and Smithsonian Astrophysical Observatory of Harvard University. Conceptual design of the telescope is lead and developed by the Centro de Ingeniería y Desarrollo Industrial (CIDESI). An overview of the feasibility study and the structural conceptual design are summarized in this paper. The telescope concept is based on telescopes already commissioned such as MMT and the Baade and Clay Magellan telescopes, building up on these proven concepts. The main differences relative to the Magellan pair are; the elevation axis is located 1 meter above the primary mirror vertex, allowing for a similar field of view at the Cassegrain and both Nasmyth focal stations; instead of using a vane ends to position the secondary mirror TSPM considers an Steward platform like MMT; finally TSPM has a larger floor distance to m1 cell than Magellans and MMT. Initially TSPM will operate with an f/5 Cassegrain station, but the design considers further Nasmyth configurations from a Cassegrain f/5 up to a Gregorian f/11. The telescope design includes 7 focal stations: 1 Cassegrain; 2 Nasmyth; and 4 folded-Cassegrain. The telescope will be designed and manufactured in Mexico, will be design in Queretaro by CIDESI and built between Queretaro and Michoacán manufacturing facilities; it will be preassembled in these facilities and disassembled to send it to the San Pedro Mártir Observatory for final integration. The azimuth and altitude structure is planned to be constructed in modules and transported by truck and shipped to Ensenada and finally to the OAN where is going

    Citizen involvement is a widely endorsed but often elusive goal in community betterment projects. An initiative by the major of San Pedro attracted funds to build a clinic and hire a doctor and attracted an American health educator to direct the project. Contrary to plan, the director's insistence on creating a representative community committee discouraged rather than increased participation. The case chronicles the interplay of interests and strategies and points toward potentially more productive approaches to issues of leadership, factionalism and public participation.

    The San Pedro Basin sits within an intermountain ecotone with the Sonoran and Chihuahuan Deserts to the west and east and the Rocky Mountain and Sierra Madre Mountain habitats to the north and south. The headwaters of the basin originate in northern Sonora and flow north into southeast Arizona. As the region's only remaining perennial stream, the San Pedro River serves as an international flyway for over 400 bird species. It is one of the western hemisphere's most ecologically diverse areas with some 20 different biotic communities, and "possesses one of the richest assemblages of land mammal species in the world." Large mining, military, and municipal entities are major users of the same groundwater resources that maintain perennial flow in the San Pedro. This presentation describes empirical evidence of the positive impacts on watershed management of scientists and policy researchers working closely with water managers and elected officials in a functioning HELP basin. We posit that when hydrologists help watershed groups understand the processes controlling water quality and quantity, and when managers and stakeholders connect these processes to social, economic and legal issues then transboundary cooperation in policymaking and water management is most effective. The distinctive physical and socioeconomic characteristics of the basin as well as differences in institutional regulations, water law issues, and their local implementations in Arizona and Sonora are discussed. We illustrate how stakeholders and scientific researchers in both countries strive to balance ecosystem needs with human demands to create new, integrated basin management. Finally, we describe how the accomplishments of the San Pedro collaborative process, including the use of environmental-conflict-resolution tools, have contributed to the UNESCO HELP (Hydrology for the Environment, Life, and Policy) agenda.

    A total of 16 moorings were deployed across the San Pedro shelf, one of the two wider embayments in the Southern California Bight, from near the surfzone to the upper-slope. On the middle and outer shelf in the summer of 2001, the currents flowed strongly equatorward at the surface and had large vertical shears through the well-stratified water column. This equatorward flow differs from predominantly poleward flow found in previous studies of the coastal margin further west. In deeper water, near the shelf break, the shears were such that near-bottom flows were poleward and incorporated into the upper parts of the Southern California Undercurrent over the slope. Mid-shelf current fluctuations, with periods of 10-25 days, along with upwelling over the shelf, were not related to local winds, but were significantly correlated with the large-scale alongshore pressure gradient. Shorter period (???7-10 days) inner shelf alongshore currents, however, were significantly correlated with the alongshore wind at the shelf break. A CEOF analysis gives two significant modes, with the first mode dominant over the outer and middle shelf. The wind-forced second mode connects the inner shelf to the poleward undercurrent over the slope such that increases in the poleward flow over the slope are correlated with increases in the equatorward current inshore of the 15 m isobath.

    We present kinematic data for 211 bright planetary nebulae in eleven Local Group galaxies: M31 (137 PNe), M32 (13), M33 (33), Fornax (1), Sagittarius (3), NGC 147 (2), NGC 185 (5), NGC 205 (9), NGC 6822 (5), Leo A (1), and Sextans A (1). The data were acquired at the Observatorio Astron\\'omico Nacional in the Sierra de San Pedro M\\'artir using the 2.1m telescope and the Manchester Echelle Spectrometer in the light of [\\ion{O}{3}]$\\lambda$5007 at a resolution of 11 km/s. A few objects were observed in H$\\alpha$. The internal kinematics of bright planetary nebulae do not depend strongly upon the metallicity or age of their progenitor stellar populations, though small systematic differences exist. The nebular kinematics and H$\\beta$ luminosity require that the nebular shells be accelerated during the early evolution of their central stars. Thus, kinematics provides an additional argument favoring similar stellar progenitors for bright planetary nebulae in all galaxies.

    Full Text Available La variabilidad de luz polarizada en el óptico ha resultado ser una herramienta poderosa para estudiar a los Blázares debido a que permite determinar la intensidad y orientación del campo magnético asociado al jet relativista. También la luz polarizada es útil para estimar el sitio donde se origina la emisión de rayos-gama, aun cuando el mecanismo físico responsable de su producción sigue sin aclararse. Más importante aún, dado que las campañas en multifrecuencias típicamente se concentran en fuentes que están en estados de alta actividad, las características de las propiedades polarimétricas de Blázares en las fases pre- y post-estallido son menos conocidas. Por tanto, hemos iniciado un programa de monitoreo dedicado de Blázares de la muestra GASP en San Pedro Mártir para estudiar sus propiedades de variabilidad. En este trabajo queremos mostrar el estado en el que se encuentra el programa presentando algunos resultados preliminares sobre la variabilidad polarim´etrica en el óptico y de rayos observada con Fermi-LAT en el blázar PKS 1510-089.

    Remote-sensing models have become increasingly popular for identifying, characterizing, monitoring, and predicting avian habitat but have largely focused on single bird species. The Normalized Difference Vegetation Index (NDVI) has been shown to positively correlate with avian abundance and richness and has been successfully applied to southwestern riparian systems which are uniquely composed of narrow bands of vegetation in an otherwise dry landscape. Desert riparian ecosystems are important breeding and stopover sites for many bird species but have been degraded due to altered hydrology and land management practices. Here we investigated the use of NDVI, coupled with vegetation, to model the avian community structure along the San Pedro River, Arizona. We also investigated how vegetation and physical features measured locally compared to those data that can be gathered through remote-sensing. We found that NDVI has statistically significant relationships with both avian abundance and species richness, although is better applied at the individual species level. However, the amount of variation explained by even our best models was quite low, suggesting that NDVI habitat models may not presently be an accurate tool for extensive modeling of avian communities. We suggest additional studies in other watersheds to increase our understanding of these bird/NDVI relationships.

  18. "Take my water": liberation through prohibition in San Pedro Chenalhó, Chiapas, Mexico.

    Eber, C

    2001-07-01

    This article explores changing views of alcohol in San Pedro Chenalhó, a township in highland Chiapas, Mexico that has been profoundly transformed by the Zapatista democracy movement. The first part of the article provides an overview of drinking in Chenalhó in the 1970s and 1980s when alcohol was still a strong symbol of community solidarity and an important part of healing ceremonies. The second part describes the period since the Zapatista uprising, a period in which indigenous women have begun to intensify their involvement in the political affairs of their communities. In their search for autonomy and to recover pride and dignity, both women and men supporters of the Zapatista movement reject alcohol as a symbol of political and economic domination. A commentary examines the relationship between the critiques of alcohol that have developed in Chenalhó since the 1970s and political economy perspectives in alcohol studies. Both explanatory frameworks focus on the power structures in which alcohol sales and use are embedded.

In addition, temperature, pH, electrical conductivity and total and fecal coliformes were determined. The statistical analysis considered a factorial treatment design; where factor A was the location point and factor B was sampling date. In addition, a multivariate technique looking for principal components was performed. The results indicated that some samples exceeded Mexican standards for As, Be, Ca, Cd, Co, Cr, Fe, Mn, Ni, Pb, Sb, Se, Sr and Zn. The As level must be considered for a red flag to the communities along the Rio San Pedro because both the monthly average level (0.10 mg L-1 and location (0.10 mg L-1 exceeded the Mexican and International norms. The multivariate analysis showed a predominant aggregation at the LP location, meaning that there was a predominance of As, Sr, Fe and Li. At the rest of the locations the elements did not present a tendency for aggregation. Statistics applied to sampling month showed that December, January, March and April were aggregated in a negative quadrant of component 1 indicating a predominance of V, Ni, Be, Fe and As. Overall, the results confirmed that this stretch of the San Pedro River is contaminated with heavy metals and other contaminants that might affect human health as well as the health of the ecosystem.

    The San Pedro River originates in northern Sonora near the town of Cananea and spans the U.S. - Mexico border into southeastern Arizona. The San Pedro Basin and perennial portions of its river support one of the most ecological diverse regions in the world. The regional groundwater aquifer which largely supports perennial flow and the associated riparian ecosystem is the primary water source for a number of communities, and for the Cananea copper mine in Sonora, which produces roughly two to three percent of the world's copper, and Ft. Huachuca, a major military installation in Arizona and the largest employer of southern Arizona. This presentation will discuss strategies and efforts over the past decade on both sides of the border to link hydrological, ecological and social sciences to aid elected officials and decision-makers in managing the basin, its growing population, and the water it so vitally depends upon. The disparate legal, cultural, economic and scientific environments, as well as the unequal degrees of decentralization and regional autonomy on the two sides of the border have resulted in distinct concerns and approaches to water resource management and varying rates of success. In the Sonoran portion of the basin water quality is the primary concern and in Arizona, water quantity is the major concern. The paper will report on sustained binational efforts and constraints encountered by researchers at the University of Arizona's NSF-funded SAHRA project and several NOAA-supported efforts in the basin region.

    The prevalence of toxicopathic liver lesions in demersal fish on the San Pedro Shelf, California was determined for a 15-year period (1988-2003). Fish livers were sampled at fixed locations as part of the Orange County Sanitation Districts (OCSD) ocean monitoring program. Histopathological examination of selected fish liver tissues was studied to determine whether the wastewater discharge had affected fish health. The prevalence of toxicopathic lesion classes neoplasms (NEO), preneoplastic foci of cellular alteration (FCA), and hydropic vacuolation (HYDVAC) varied among species and locations. For all species sampled, severe lesions occurred in 6.2% of the fish examined (n=7,694). HYDVAC (4.1%) was the most common toxicopathic lesion type followed by FCA (1.4%) and NEO (0.7%). HYDVAC occurred only in white croaker (Genyonemus lineatus), accounting for 84.8% of the toxicopathic lesions for this species. Prevalence of HYDVAC, NEO, and FCA in white croaker was 15.2, 2.0, and 0.7%, respectively. The prevalence of HYDVAC and NEO in white croaker increased with age and size but there was no sexual difference. A linear regression model was used for hypothesis testing to account for significant differences in fish size (and age for croakers) at the different sampling locations. This analysis showed that for HYDVAC there was no spatial or location effect for lesion rate or size/age of onset. For NEO, the model predicted that white croaker near the wastewater outfall may acquire these lesions at a smaller size/younger age, and at a higher rate, than at other sites. However, this result may be biased due to the unequal size frequency distributions and the low prevalence of NEO in white croaker at the different sampling sites. Bigmouth sole (Hippoglossina stomata) had a prevalence of FCA and NEO of 1.3 and 0.35%, respectively, but the prevalence and distribution of lesions was too few for statistical testing. There was no sexual difference for lesion prevalence in hornyhead

    Full Text Available En el presente trabajo se reportan los resultados de un estudio arqueomagnético realizado en un horno para la quema de cal encontrado en la hacienda henequenera de San Pedro Cholul, localizada al noroeste de la ciudad de Mérida en el estado de Yucatán, México. La finalidad del estudio es establecer una cronología confiable y analizar las posibles consecuencias sociales, económicas y ambientales de este asentamiento, el cual existió posiblemente desde mediados del siglo XIX hasta los años sesenta del siglo pasado. Para la determinación de la cronología, se utilizó el método de datación arqueomagnética a estructuras pirotecnológicas de estas características. Las muestras estudiadas provienen de rocas y ladrillos del horno y arrojan una edad entre 1835 y 1896, la cual concuerda con la información histórica disponible y se interpreta como el periodo de producción más importante de la región. ENGLISH: This paper presents the results of an archaeomagnetic study carried out on a lime burning kiln at the henequen hacienda of San Pedro Cholul (northwest of the city of Merida in the state of Yucatan, Mexico. The purpose of the study is to establish a reliable chronology and to estimate the possible social, economic and environmental implications of this settlement, which may have existed from the middle of the nineteenth century until the 1960s. Archaeomagnetic dating was carried out on samples obtained from rocks and bricks from the kiln and give an age between 1835 and 1896. This date range agrees with available historical information and is interpreted as the most important production period of the region.

    Chapter 1.—We measured bird abundance and richness along the upper San Pedro River in 2005 and 2006, in order to document how beavers (Castor canadensis) may act as ecosystem engineers after their reintroduction to a desert riparian area in the Southwestern United States. In areas where beavers colonized, we found higher bird abundance and richness of bird groups, such as all breeding birds, insectivorous birds, and riparian specialists, and higher relative abundance of many individual species—including several avian species of conservation concern. Chapter 2.—We conducted bird surveys in riparian areas along the upper San Pedro River in southeastern Arizona (United States) and northern Sonora (Mexico) in order to describe factors influencing bird community dynamics and the distribution and abundance of species, particularly those of conservation concern. These surveys were also used to document the effects of the ecosystem-altering activities of a recently reintroduced beavers (Castor canadensis). Chapter 3.—We reviewed Southwestern Willow Flycatcher (Empidonax traillii extimus) nest records and investigated the potential for future breeding along the upper San Pedro River in southeastern Arizona, where in July 2005 we encountered the southernmost verifiable nest attempt for the species. Continued conservation and management of the area’s riparian vegetation and surface water has potential to contribute additional breeding sites for this endangered Willow Flycatcher subspecies. Given the nest record along the upper San Pedro River and the presence of high-density breeding sites to the north, the native cottonwood-willow forests of the upper San Pedro River could become increasingly important to E. t. extimus recovery, especially considering the anticipated effect of the tamarisk leaf beetle (Diorhabda carinulata) on riparian habitat north of the region.

    We present comprehensive seeing statistics for the San Pedro M\\'artir site derived from the Thirty Meter Telescope site selection data. The observations were obtained between 2004 and 2008 with a Differential Image Motion Monitor (DIMM) and a Multi Aperture Scintillation Sensor (MASS) combined instrument (MASS--DIMM). The parameters that are statistically analised here are: whole atmosphere seeing -measured by the DIMM-; free atmosphere seeing --measured by the MASS--; and ground-layer seeing (GL) --difference between the total and free-atmosphere seeing--. We made a careful data coverage study along with statistical distributions of simultaneous MASS--DIMM seeing measurements, in order to investigate the nightly, monthly, seasonal, annual and global behaviour, as well as possible hourly seeing trends. Although this campaign covers five years, the sampling is uneven, being 2006 and 2007 the best sampled years in terms of seasonal coverage. The overall results yield a median seeing of 0.78 (DIMM), 0.37 (MASS) ...

    Full Text Available Planting and consumption of maize are identity and determining activities in the evolution of population’s food heritage, since they contribute to food security and preservation of the biocultural heritage. Based on qualitative collection of information from producers and consumers of hand-made maize tortillas in San Pedro del Rosal, Atlacomulco, Estado de Mexico, an ethnographic study was conducted. From an anthropological perspective, the production of tortillas was characterized in order to analyze the know-how concerning this food, typical of central Mexico’s culinary identity. For tortilla producers, the know-how constitutes an identity heritage, as well as possibly a strategy for generating an income. In the case of consumers, it was concluded that they choose hand-made tortillas given their symbolic value.

    2010-01-01

    A consortium of federal, academic, and nongovernment organization (NGO) partners have established a collaborative research enterprise in the San Pedro River Basin to develop methods, standards, and tools to assess and value ecosystem goods and services. The central premise of ecosystem services research is that human condition is intrinsically linked to the environment. Human health and well-being (including economic prosperity) depend on important supporting, regulating, provisioning, and cultural services that we derive from our surrounding ecosystems. The AGAVES project is intended as a demonstration study for incorporating ecosystem services information into resource management policy and decisionmaking. Accordingly, a nested, multiscale project design has been adopted to address a range of stakeholder information requirements. This design will further facilitate an evaluation of how well methods developed in this project can be transferred to other areas.

    This report details the findings of the Bureau of Land Management–U.S. Geological Survey Ecosystem Services Valuation Pilot Study. This project evaluated alternative methods and tools that quantify and value ecosystem services, and it assessed the tools’ readiness for use in the Bureau of Land Management decisionmaking process. We tested these tools on the San Pedro River watershed in northern Sonora, Mexico, and southeast Arizona. The study area includes the San Pedro Riparian National Conservation Area (managed by the Bureau of Land Management), which has been a focal point for conservation activities and scientific research in recent decades. We applied past site-specific primary valuation studies, value transfer, the Wildlife Habitat Benefits Estimation Toolkit, and the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) and Artificial Intelligence for Ecosystem Services (ARIES) models to value locally important ecosystem services for the San Pedro River watershed—water, carbon, biodiversity, and cultural values. We tested these approaches on a series of scenarios to evaluate ecosystem service changes and the ability of the tools to accommodate scenarios. A suite of additional tools were either at too early a stage of development to run, were proprietary, or were place-specific tools inappropriate for application to the San Pedro River watershed. We described the strengths and weaknesses of these additional ecosystem service tools against a series of evaluative criteria related to their usefulness for Bureau of Land Management decisionmaking. Using these tools, we quantified gains or losses of ecosystem services under three categories of scenarios: urban growth, mesquite management, and water augmentation. These results quantify tradeoffs and could be useful for decisionmaking within Bureau of Land Management district or field offices. Results are accompanied by a relatively high level of uncertainty associated with model outputs, valuation

Con 23 especies capturadas en el sitio I, 17 en el II y 14 en el III. En la época de secas se obtuvo mayor riqueza con 21 especies, lluvias con 17 y cinco en nortes. La mayor densidad se mostró en el sitio II (0.23ind./m², seguido de los sitios I y III (0.12, 0.12ind./m². La mayor biomasa fue en secas (8.30g/m², seguida de lluvias (2.1g/m² y por último nortes (0.01g/m². La mayor densidad se mostró en secas (0.43ind./m² y la mínima en nortes (0.023ind./m². Las especies dominantes en densidad según el diagrama Olmstead-Tukey fueron: Petenia splendida, Vieja heterospila, Vieja synspila, Dorosoma petenense y Astyanax aeneus. Por lo tanto, existieron diferencias significativas en los parámetros ecológicos y ambientales. Al considerar la variación en la riqueza podemos concluir que los humedales del río San Pedro, es un sistema donde la composición de la ictiofauna responde a las fluctuaciones espaciales y temporales.

  9. Estimation of potential pollution from mine tailings in the San Pedro River (1993-2005), Mexico-US border

    The San Pedro River (SPR) is located in northern Sonora (Mexico) and southeastern Arizona (USA). SPR is a transboundary river that develops along the Sonora (Mexico) and Arizona (USA) border, and is considered the main source of water for a variety of users (human settlements, agriculture, livestock, and industry). The SPR originates in the historic Cananea mining area, which hosts some of the most important copper mineralizations in Mexico. Acid mine drainage derived from mine tailings is currently reaching a tributary of the SPR near Cananea City, resulting in the contamination of the SPR with heavy metals and sulfates in water and sediments. This study documents the accumulation and distribution of heavy metals in surface water along a segment of the SPR from 1993 to 2005. Total concentrations of Cd, Cu, Fe, Mn, Pb, and Zn in surface waters are above maximum permissible levels in sampling sites near mine tailing deposits. Nevertheless, a significant decrease in the Fe and SO4 2- in surface water (SO4 2-: 7,180-460.39 mg/L; Fe: 1,600-9.51 mg/L) as well as a gradual decrease in the heavy and transition metal content were observed during the period from 1994 to 2005. Approximately 2.3 km downstream of the mine tailings, the heavy metal content of the water drops quickly following an increase in pH values due to the discharging of wastewater into the river. The attenuation of the heavy metal content in surface waters is related to stream sediment precipitation (accompanied by metal coprecipitation and sorption) and water dilution. Determining the heavy metal concentration led to the conclusion that the Cananea mining area and the San Pedro River are ecosystems that are impacted by the mining industry and by untreated wastewater discharges arising from the city of Cananea (Sonora, Mexico).

    Full Text Available The UAH team is developing successive projects of heritage evaluation in the International Tagus, focused on the megalithic culture. Our surveys, based on the theoretical statement of a predictive model that considers the presence of outdoor paintings, make the Sierra de San Pedro one of the most important schematic painting groups of the Iberian Peninsula. Its parallel development to the sites with outdoor engravings in the International Tagus draws a complex set of symbols with a major role in the definition of megalithic territories. The identification of Palaeolithic figures coincides with similar recurrences documented in outdoor sites of the western peninsula, pointing to the resort to the past as one of the arguments of vindication and use of traditional territories.

    El equipo de la UAH viene desarrollando sucesivos proyectos de valoración patrimonial en el Tajo Internacional centrados en la cultura megalítica. Nuestras prospecciones a partir de la exposición teórica de un modelo predictivo que considera la presencia de pinturas al aire libre, hacen de la Sierra de San Pedro uno de los más importantes conjuntos de la pintura esquemática de la Península Ibérica. Su desarrollo paralelo a los yacimientos con grabados al aire libre del Tajo Internacional dibuja un complejo entramado de símbolos con un importante papel en la definición de los territorios megalíticos. La identificación de figuras paleolíticas coincide con recurrencias similares documentadas en los yacimientos al aire libre del occidente peninsular, apuntando al recurso al pasado como uno de los argumentos de reivindicación y uso de territorios tradicionales.

    Full Text Available San Pedro cliff (Figure 1 is a dihedral 65.5 m high, which has progressed to place itself at 23.8 m from the Alhambra wall-palace that is a heritage of the Humankind. Active normal faults surrounding the cliff have created an extension tectonic regime that loosens the ground and activates the slab falls. One of the faces of the dihedral is a major fault. The cliff’s factor of safety subject to the 1000 years return period earthquake is 0.73. The preservation solution proposed is a posttensioned high elastic limit wire mesh and autochthonous vegetation. With this reinforcement, the factor of safety under that earthquake raises to a value around one. A computer simulation has permitted to analyse the environmental impact.La muralla-palacio de La Alhambra, que es Patrimonio de la Humanidad, se ve amenazada por el avance del Tajo de San Pedro (Figura1, un diedro de 65,5 m de altura, que corta la colina de La Alhambra y que se ha situado a sólo 23,8 m de ella. Existe en la zona un régimen tectónico de extensión que afloja el terreno y activa la caída de lajas. Otra causa importante del deterioro del Tajo es la erosión. El coeficiente de seguridad al deslizamiento del Tajo sometido al terremoto de periodo de retorno de 1.000 años es de 0,73. La solución propuesta para su preservación es una malla de alambre postesada de alto límite elástico y revegetación autóctona. La presión que puede llegar a aplicar la malla en servicio eleva el coeficiente de seguridad con sismo a un valor próximo a uno. Mediante una simulación en ordenador se ha analizado el impacto ambiental.

    Laurel J. Lacher

    2014-11-01

    Full Text Available The San Pedro River originates in Sonora, Mexico, and flows north through Arizona, USA, to its confluence with the Gila River. The 92-km Upper San Pedro River is characterized by interrupted perennial flow, and serves as a vital wildlife corridor through this semiarid to arid region. Over the past century, groundwater pumping in this bi-national basin has depleted baseflows in the river. In 2007, the United States Geological Survey published the most recent groundwater model of the basin. This model served as the basis for predictive simulations, including maps of stream flow capture due to pumping and of stream flow restoration due to managed aquifer recharge. Simulation results show that ramping up near-stream recharge, as needed, to compensate for downward pumping-related stress on the water table, could sustain baseflows in the Upper San Pedro River at or above 2003 levels until the year 2100 with less than 4.7 million cubic meters per year (MCM/yr. Wet-dry mapping of the river over a period of 15 years developed a body of empirical evidence which, when combined with the simulation tools, provided powerful technical support to decision makers struggling to manage aquifer recharge to support baseflows in the river while also accommodating the economic needs of the basin.

    Groundwater pumping along portions of the binational San Pedro River has depleted aquifer storage that supports baseflow in the San Pedro River. A consortium of 23 agencies, business interests, and non-governmental organizations pooled their collective resources to develop the scientific understanding and technical tools required to optimize the management of this complex, interconnected groundwater-surface water system. A paradigm shift occurred as stakeholders first collaboratively developed, and then later applied, several key hydrologic simulation and monitoring tools. Water resources planning and management transitioned from a traditional water budget-based approach to a more strategic and spatially-explicit optimization process. After groundwater modeling results suggested that strategic near-stream recharge could reasonably sustain baseflows at or above 2003 levels until the year 2100, even in the presence of continued groundwater development, a group of collaborators worked for four years to acquire 2250 hectares of land in key locations along 34 kilometers of the river specifically for this purpose. These actions reflect an evolved common vision that considers the multiple water demands of both humans and the riparian ecosystem associated with the San Pedro River.

    Full Text Available This article aims to analyze, through ethnographic observation of the Cemetery San Pedro in Medellin (Colombia, the recent trend of tombstones decoration in confluence with the proposal of structure and aesthetics of the social network Facebook. This correlation between the virtual language of Facebook and the ritual language of the tombs, is much more complex than a mere coincidence so we propose a thorough comparative reading of these two universes of representation for the meeting and communication, is needed to provide a better understanding of the two phenomena. Both are plethoric spaces that reveal the relentless pursuit of the subject to perpetuate their presence, to tell about their lives and deaths, to eternalize their expressions of affection, love and devotion, and to continue their social relationships despite physical or virtual distance, as scenarios with common origins and intentions, where appearing is more important than being. Currently, the “walls” of both the Cemetery and Facebook, serve as communicational sceneries that share publicly and shamelessly intimate details; where family relationships are announced; idyllic havens are displayed as photographic backgrounds; messages are left and profiles with the strong necessity to achieve the long-awaited update transcendence.

These results quantify tradeoffs and could be useful for decisionmaking within Bureau of Land Management district or field offices. Results are accompanied by a relatively high level of uncertainty associated with model outputs, valuation

    An approach was developed to characterize the hydrologic impacts of urban expansion through time for the San Pedro River, a watershed of immense international importance that straddles the U.S./Mexico border. Future urban growth is a key driving force altering local and regional hydrology and is represented by decadal changes in housing density maps from 2010 to 2100 derived from the Integrated Climate and Land-Use Scenarios (ICLUS) database. ICLUS developed future housing density maps by adapting the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) social, economic, and demographic storylines to the conterminous United States. To characterize the hydrologic impacts of future growth, the housing density maps were reclassified to National Land Cover Database 2006 land cover classes and used to parameterize the Soil and Water Assessment Tool (SWAT) using the Automated Geospatial Watershed Assessment (AGWA) tool. The presentation will report 1) the methodology for adapting the ICLUS data for use in AGWA as an approach to evaluate basin-wide impacts of development on water-quantity and -quality, 2) initial results of the application of the methodology, and 3) discuss implications of the analysis.

    Full Text Available Saint Peter is the great unknown of the Iscar churches due to the demolition of most of its architectural structures and the insufficient characteristics of the scarcely preserved evidence, hidden between contemporary buildings. Nevertheless, the recent demolition of one of the buildings attached to the eastern side of the former temple, where the Romanesque remains are concentrated, has brought to light a decisive part of the apse and the presbytery along with the front closure of the southern aisle. This discovery has allowed an indepth analysis and an approach to what could have been the primitive building.San Pedro es la gran desconocida de las iglesias de Íscar a consecuencia de la demolición de la mayor parte de sus estructuras arquitectónicas y de la insuficiente representatividad de las escasas evidencias conservadas, enmascaradas entre edificios contemporáneos.

    Plant macrofossils from 38 packrat middens spanning the last ~ 33,000 cal yr BP record vegetation between ~ 650 and 900 m elevation along the eastern escarpment of the Sierra San Pedro Mártir, northern Baja California. The middens span most of the Holocene, with a gap between ~ 4600 and 1800 cal yr BP, but coverage in the Pleistocene is uneven with a larger hiatus between 23,100 and 14,400 cal yr BP. The midden flora is relatively stable from the Pleistocene to Holocene. Exceptions include Pinus californiarum, Juniperus californica and other chaparral elements that were most abundant > 23,100 cal yr BP and declined after 14,400 cal yr BP. Despite being near the chaparral/woodland-desertscrub ecotone during glacial times, the midden assemblages reflect none of the climatic reversals evident in the glacial or marine record, and this is corroborated by a nearby semi-continuous pollen stratigraphy from lake sediments. Regular appearance of C 4 grasses and summer-flowering annuals since 13,600 cal yr BP indicates occurrence of summer rainfall equivalent to modern (JAS average of ~ 80-90 mm). This casts doubt on the claim, based on temperature proxies from marine sediments in the Guaymas Basin, that monsoonal development in the northern Gulf and Arizona was delayed until after 6200 cal yr BP.

    The Upper Triassic (Adamanian LVF) Ojo Huelos Member of the San Pedro Arroyo Formation (Chinle Group) is a distinctive, carbonate-rich unit that occurs in the lower Chinle section of central New Mexico. The member consists mainly of micritic lime mudstones, ostracodal wackestones to grainstones, peloidal grainstones and distinctive pisolitic rudstones, interbedded with fine-grained siliciclastic mudstones. Most limestones exhibit some evidence of pedogenic brecciation and root penetration, and porous fabrics similar to those of modern limestone tufas occur locally. The interbedded mudstones are typically lenticular and commonly display a blocky ped fabric in which subequant peds are separated by sparry calcite veins. Fossils from the Ojo Huelos Member are freshwater (darwinulid) ostracodes, various freshwater fishes and aquatic/amphibious tetrapods-metoposaurs and phytosaurs. We interpret the carbonate facies as the deposits of carbonate lakes, ponds and wetlands that were partly spring-fed, whereas the interbedded and surrounding mudstones were alluvial in origin. The groundwater and overland hydrology of the region was likely controlled by the relative proximity to an upland recharge area in the Mogollon Highlands to the south, but sedimentary fabrics record strong overprinting by desiccation and pedogenic reworking. Consequently, we interpret the Ojo Huelos Member as recording a climate that varied from subhumid to semi-arid, which caused episodic falls in the hydrologic base-level. This resulted in landscape degradation, exemplified by significant pedogenic and erosional reworking of the carbonate sediments and fluvial incision.

    Sediment bacteria play important roles in the biogeochemistry of ocean sediments; however, factors influencing assemblage composition have not been extensively studied. We examined extractable sediment bacterial abundance, the composition of bacterial assemblages using a high-throughput molecular fingerprinting approach, and several sediment biogeochemical parameters (organic matter content and alkaline phosphatase activity), along a 35 km transect from Point Fermin, Southern California, to Santa Catalina Island, across the approximately 900-m-deep San Pedro Basin. Automated rRNA intergenic spacer analysis (ARISA) demonstrated that in two spatially isolated shallow (approximately < 60 m, on opposite sides of the channel) sediment environments, assemblages were more similar to each other than to deeper communities. Distinct communities existed in deeper and shallower sediments, and stations within the deep basin over 2 km apart contained remarkably similar assemblage fingerprints. The relative contribution to total amplified DNA fluorescence of operational taxonomic units (OTUs) was significantly correlated to that of other OTUs in few comparisons (2.7% of total), i.e. few bacterial types were found together or apart consistently. The relative proportions within assemblages of only a few OTU were significantly correlated to measured physicochemical parameters (organic matter content and wet/dry weight ratio of sediments) or enzyme (alkaline phosphatase) activities. A low percentage of shared OTU between shallow and deep sediments, and the presence of similar, but spatially isolated assemblages suggests that bacterial OTU may be widely dispersed over scales of a few kilometres, but that environmental conditions select for particular assemblages.

    Full Text Available Myctophids (Myctophidae are a group of abundant mesopelagic fishes in the world's oceans and are known as the main feeding resource for several high trophic level predators. Changes in abundance may be related to population size of some commercially important species that feed on them. Only two of the myctophid species reported for the Gulf of California were found in the present study: Benthosema panamense and Triphoturus mexicanus. The highest abundance and biomass of myctophids were found during the warm season (June and September, with B. panamense being the most abundant species (20,954 ind 1000 m-3, as well as the one with highest biomass (17,165.8 g 1000 m-3. B. panamese had a size mode interval of 35-40 mm, while T. mexicanus presented a size mode interval of 40-45 mm; both species had negative allometric growth. During the temperate season (February and April B. panamense was distributed in the northwest, west, and southern regions around the island, while T. mexicanus was found in the north, west, and southern regions. During the warm season B. panamense was found distributed around the entire island and T. mexicanus was found in the west, south, and east regions of the island. These species are common around San Pedro Martir Island, with the highest values of abundance and biomass occurring during summer upwelling's.

    Although the number of ecosystem service modeling tools has grown in recent years, quantitative comparative studies of these tools have been lacking. In this study, we applied two leading open-source, spatially explicit ecosystem services modeling tools – Artificial Intelligence for Ecosystem Services (ARIES) and Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) – to the San Pedro River watershed in southeast Arizona, USA, and northern Sonora, Mexico. We modeled locally important services that both modeling systems could address – carbon, water, and scenic viewsheds. We then applied managerially relevant scenarios for urban growth and mesquite management to quantify ecosystem service changes. InVEST and ARIES use different modeling approaches and ecosystem services metrics; for carbon, metrics were more similar and results were more easily comparable than for viewsheds or water. However, findings demonstrate similar gains and losses of ecosystem services and conclusions when comparing effects across our scenarios. Results were more closely aligned for landscape-scale urban-growth scenarios and more divergent for a site-scale mesquite-management scenario. Follow-up studies, including testing in different geographic contexts, can improve our understanding of the strengths and weaknesses of these and other ecosystem services modeling tools as they move closer to readiness for supporting day-to-day resource management.

    Full Text Available Churches usually ascribed to the Visigothic period are difficult to place in a clear cultural framework, with the result that other dating methods assume a vital importance. In this study, dendro-chronqlogy, carbon-14 dating, and archaeological evidence combine to give a terminus post quem of AD 330-474 for the pine-trunk employed for the beam of the church of San Pedro de la Nave (''pino albar o laricio''. Given the trunk's completed dendro-chronological sequence of 282 years, the beam in its present location must constitute a case of re-use. At least some of the other elements employed in the construction of the building must also have been re-used. The discussion serves to illustrate how an interdisciplinary approach can be applied to the study of early medieval Spanish churches and how it might be refined to produce ever more reliable and valuable results.Las dudas sobre la adecuada adscripción cultural de las iglesias consideradas de época visigoda, obliga a conseguir dataciones lo más seguras posibles. Por ello se ha realizado este estudio interdisciplinar, que compagina la dendrodatación, la datación por carbono-14 y la arqueología y cuyo resultado data el árbol de pino albar o laricio con el que se talló la viga de la iglesia de S. Pedro de La Nave en una fecha post quem de 330-474 AD (ref. CSIC-1318. Sus caracteres anatómicos nos indican que la secuencia dendrocronológica obtenida de 282 años es completa, por lo que la viga tuvo que ser reutilizada, como debió ocurrir al menos con parte del material de construcción. Los análisis han servido para ensayar la aplicación de esta metodología a las iglesias altomedievales españolas y mejorarla para lograr resultados más fiables y precisos.

    In the summer of 2001, a coastal ocean measurement program in the southeastern portion of San Pedro Bay, CA, was designed and carried out. One aim of the program was to determine the strength and effectiveness of local cross-shelf transport processes. A particular objective was to assess the ability of semidiurnal internal tidal currents to move suspended material a net distance across the shelf. Hence, a dense array of moorings was deployed across the shelf to monitor the transport patterns associated with fluctuations in currents, temperature and salinity. An associated hydrographic program periodically monitored synoptic changes in the spatial patterns of temperature, salinity, nutrients and bacteria. This set of measurements show that a series of energetic internal tides can, but do not always, transport subthermocline water, dissolved and suspended material from the middle of the shelf into the surfzone. Effective cross-shelf transport occurs only when (1) internal tides at the shelf break are strong and (2) subtidal currents flow strongly downcoast. The subtidal downcoast flow causes isotherms to tilt upward toward the coast, which allows energetic, nonlinear internal tidal currents to carry subthermocline waters into the surfzone. During these events, which may last for several days, the transported water remains in the surfzone until the internal tidal current pulses and/or the downcoast subtidal currents disappear. This nonlinear internal tide cross-shelf transport process was capable of carrying water and the associated suspended or dissolved material from the mid-shelf into the surfzone, but there were no observation of transport from the shelf break into the surfzone. Dissolved nutrients and suspended particulates (such as phytoplankton) transported from the mid-shelf into the nearshore region by nonlinear internal tides may contribute to nearshore algal blooms, including harmful algal blooms that occur off local beaches.

    Results on runoff estimates as a response to land-use and land-cover changes are presented. We used remote sensing and GIS techniques with rainfall time-series data, spatial ancillary information, and the curve-number method (NRCS-CN) to assess the runoff response in the San Pedro subbasin. Thematic maps with eight land-cover classes derived from satellite imagery classification (1973, 1990, and 2000) and hydrologic soil-group maps were used as the input for the runoff calculation. About 20% to 25% of the subbasin landscape has changed since 1973, mainly as consequence of the growth of agriculture. Forest is the main cover, although further analyses indicate that forest is degrading from good to poor conditions when evaluated as a function of the spectral response. Soils with low infiltration rates, classified as the hydrological soil-group "C", were dominant in the area (52%). The overlaying of all the hydrological soil groups with the land-use map produced a total of 43 hydro-group and land-use categories for which runoff was calculated using the curve-number method. Estimates of total runoff volumes (26 x 10(6) m3) were similar for the three dates analyzed in spite of landscape changes, but there were temporal variations among the hydro-group and land-use categories as a consequence. Changes are causing the rise of covers with high runoff potential and the increase of runoff depth is expected, but it can be reversed by different management of subbasin hydro-groups and land-use units.

    The seismic hazard posed by offshore faults for coastal communities in Southern California is poorly understood and may be considerable, especially when these communities are located near long faults that have the ability to produce large earthquakes. The San Diego Trough fault (SDTF) and San Pedro Basin fault (SPBF) systems are active northwest striking, right-lateral faults in the Inner California Borderland that extend offshore between San Diego and Los Angeles. Recent work shows that the SDTF slip rate accounts for 25% of the 6-8 mm/yr of deformation accommodated by the offshore fault network, and seismic reflection data suggest that these two fault zones may be one continuous structure. Here, we use recently acquired CHIRP, high-resolution multichannel seismic (MCS) reflection, and multibeam bathymetric data in combination with USGS and industry MCS profiles to characterize recent deformation on the SDTF and SPBF zones and to evaluate the potential for an end-to-end rupture that spans both fault systems. The SDTF offsets young sediments at the seafloor for 130 km between the US/Mexico border and Avalon Knoll. The northern SPBF has robust geomorphic expression and offsets the seafloor in the Santa Monica Basin. The southern SPBF lies within a 25-km gap between high-resolution MCS surveys. Although there does appear to be a through-going fault at depth in industry MCS profiles, the low vertical resolution of these data inhibits our ability to confirm recent slip on the southern SPBF. Empirical scaling relationships indicate that a 200-km-long rupture of the SDTF and its southern extension, the Bahia Soledad fault, could produce a M7.7 earthquake. If the SDTF and the SPBF are linked, the length of the combined fault increases to >270 km. This may allow ruptures initiating on the SDTF to propagate within 25 km of the Los Angeles Basin. At present, the paleoseismic histories of the faults are unknown. We present new observations from CHIRP and coring surveys at

    The San Pedro River in the southwestern United States retains a natural flood regime and has several reaches with perennial stream flow and shallow ground water. However, much of the river flows intermittently. Urbanization-linked declines in regional ground-water levels have raised concerns over the future status of the riverine ecosystem in some parts of the river, while restoration-linked decreases in agricultural ground-water pumping are expected to increase stream flows in other parts. This study describes the response of the streamside herbaceous vegetation to changes in stream flow permanence. During the early summer dry season, streamside herbaceous cover and species richness declined continuously across spatial gradients of flow permanence, and composition shifted from hydric to mesic species at sites with more intermittent flow. Hydrologic threshold values were evident for one plant functional group: Schoenoplectus acutus, Juncus torreyi, and other hydric riparian plants declined sharply in cover with loss of perennial stream flow. In contrast, cover of mesic riparian perennials (including Cynodon dactylon, an introduced species) increased at sites with intermittent flow. Patterns of hydric and mesic riparian annuals varied by season: in the early summer dry season their cover declined continuously as flow became more intermittent, while in the late summer wet season their cover increased as the flow became more intermittent. Periodic drought at the intermittent sites may increase opportunities for establishment of these annuals during the monsoonal flood season. During the late summer flood season, stream flow was present at most sites, and fewer vegetation traits were correlated with flow permanence; cover and richness were correlated with other environmental factors including site elevation and substrate nitrate level and particle size. Although perennial-flow and intermittent-flow sites support different streamside plant communities, all of the plant

La cronología de ancho de anillos está compuesta por 33 series de 22 árboles y cubre el período 1968-2013. El crecimiento de los árboles estuvo relacionado negativamente con la temperatura mínima mensual del mes de abril del año corriente. Se observó una relación positiva y significativa entre la cronología de crecimiento y la precipitación de la estación de Santa Ana para los meses de marzo del año previo y diciembre del año actual de crecimiento. Las horas sol mensuales de abril del año corriente tienen una correlación significativa con el crecimiento radial. Existe influencia de las precipitaciones del verano previo y primavera del año corriente favoreciendo el crecimiento del árbol. El árbol entra en dormancia, posiblemente por las bajas temperaturas de otoño. El amplio rango de distribución y la utilización histórica de su madera en construcciones en el pasado, abre la posibilidad de extender temporalmente los registros dendrocronológicos, en los Andes centrales de Perú.

  6. Using Radium Isotopes to Evaluate Cross-shelf Dispersion in the Coastal Ocean: Application to San Pedro Bay, CA

    The short-lived radium isotopes Ra-223 (11 day half life) and Ra-224 (3.6 day half-life) are potentially useful for evaluating cross-shelf dispersion rates in the coastal ocean. A requirement for this application is that their source function and its variability in time and space must be defined. The primary mechanisms for introducing radium into coastal surface waters include: (1) wave and tide-driven circulation of water through permeable beach sands, (2) input from the seafloor due to molecular diffusion and circulation of bottom water through surficial sands, (3) flow of water rich in Ra from marshes and estuaries, and (4) net advection of groundwater. The importance of these inputs to San Pedro Bay was determined from concentrations in waters collected from each of these potential sources. In most of the region, mechanism (2) supplies 90% of the input, although mechanisms (1) and (2) may become dominant locally as the coastal morphology varies in the longshore direction. Longshore variations in the composition of beach sand and the presence of persistent coastal eddies create longshore gradients in Ra concentration that are significant in this region. Temporal variations in shoreline concentrations on time scales 6-8 hours reflect variations in mechanism (1) as tides rise and fall, with drainage of water from the beach face creating higher concentrations during the falling tide. Despite these complications in characterizing the source function, the distribution of short-lived Ra isotopes is useful in constraining the rate of horizontal mixing. A two-dimensional advection-diffusion model was best fit with an eddy diffusivity of 1.3+/-0.2 m2/s over length scales of several km offshore, with a value about 50% smaller in the littoral zone. The scale dependence of eddy diffusivity is also apparent in the distribution of Ra-228, which requires lower eddy diffusivities in the nearshore than in the offshore region. A budget for Ra-226 indicates that little groundwater

    This project is part of a multidisciplinary effort aimed at understanding the impacts of climate variability and change on the ecological services provided by riparian ecosystems in semiarid watersheds of the southwestern United States. Valuing the environmental and recreational services provided by these ecosystems in the future requires a numerical simulation approach to estimate streamflow in ungauged tributaries as well as diffuse and direct recharge to groundwater basins. In this work, we utilize a distributed hydrologic model known as the TIN-based Real-time Integrated Basin Simulator (tRIBS) in the upper Santa Cruz and San Pedro basins with the goal of generating simulated hydrological fields that will be coupled to a riparian groundwater model. With the distributed model, we will evaluate a set of climate change and population scenarios to quantify future conditions in these two river systems and their impacts on flood peaks, recharge events and low flows. Here, we present a model confidence building exercise based on high performance computing (HPC) runs of the tRIBS model in both basins during the period of 1990-2000. Distributed model simulations utilize best-available data across the US-Mexico border on topography, land cover and soils obtained from analysis of remotely-sensed imagery and government databases. Meteorological forcing over the historical period is obtained from a combination of sparse ground networks and weather radar rainfall estimates. We then focus on a comparison between simulation runs using ground-based forcing to cases where the Weather Research Forecast (WRF) model is used to specify the historical conditions. Two spatial resolutions are considered from the WRF model fields - a coarse (35-km) and a downscaled (10- km) forcing. Comparisons will focus on the distribution of precipitation, soil moisture, runoff generation and recharge and assess the value of the WRF coarse and downscaled products. These results provide confidence in

    A numerical ground-water model was developed to simulate seasonal and long-term variations in ground-water flow in the Sierra Vista subwatershed, Arizona, United States, and Sonora, Mexico, portions of the Upper San Pedro Basin. This model includes the simulation of details of the groundwater flow system that were not simulated by previous models, such as ground-water flow in the sedimentary rocks that surround and underlie the alluvial basin deposits, withdrawals for dewatering purposes at the Tombstone mine, discharge to springs in the Huachuca Mountains, thick low-permeability intervals of silt and clay that separate the ground-water flow system into deep-confined and shallow-unconfined systems, ephemeral-channel recharge, and seasonal variations in ground-water discharge by wells and evapotranspiration. Steady-state and transient conditions during 1902-2003 were simulated by using a five-layer numerical ground- water flow model representing multiple hydrogeologic units. Hydraulic properties of model layers, streamflow, and evapotranspiration rates were estimated as part of the calibration process by using observed water levels, vertical hydraulic gradients, streamflow, and estimated evapotranspiration rates as constraints. Simulations approximate observed water-level trends throughout most of the model area and streamflow trends at the Charleston streamflow-gaging station on the San Pedro River. Differences in observed and simulated water levels, streamflow, and evapotranspiration could be reduced through simulation of climate-related variations in recharge rates and recharge from flood-flow infiltration.

    Full Text Available We have analyzed how the collaborative development process of a decision-support system (DSS model can effectively contribute to increasing the resilience of regional social–ecological systems. In particular, we have focused on the case study of the transboundary San Pedro Basin, in the Arizona-Sonora desert region. This is a semi-arid watershed where water is a scarce resource used to cover competing human and environmental needs. We have outlined the essential traits in the development of the decision-support process that contributed to an improvement of water-resources management capabilities while increasing the potential for consensual problem solving. Comments and feedback from the stakeholders benefiting from the DSS in the San Pedro Basin are presented and analyzed within the regional (United States–Mexico boundary, social, and institutional context. We have indicated how multidisciplinary collaboration between academia and stakeholders can be an effective step toward collaborative management. Such technology transfer and capacity building provides a common arena for testing water-management policies and evaluating future scenarios. Putting science at the service of a participatory decision-making process can provide adaptive capacity to accommodate future change (i.e., building resilience in the management system.

    The prevalence and social and health aspects of smoking habits among physicians of the Hospital San Pedro de Alcántara (Cáceres) were evaluated with the questionnaire used in the course on smoking habits delivered by the INSALUD in 1988. The sample consisted of 123 physicians. 47.1% (+8.7%) declared to be smokers. This prevalence is higher than that in the general population. The rate of female nonsmokers was significantly higher than that of male nonsmokers (p less than 0.05). 51.7% of smokers had not made any attempt to give up smoking. 90% thought that the role of the doctors as a model is important, and that the health system should undertake their treatment. 97.2% declared to lack therapeutic resources. The results disclose the need for specific programs directed to exemplary groups of professionals, such as those devoted to health care, so as to achieve a reduction in the smoking habit.

    Full Text Available We analysed the distribution of soft bottom sipunculansfrom San Pedro del Pinatar (Western Mediterranean. This study was carried out from December 2005 to June 2010, sampling with biannual periodicity (June and December. Physical and chemical parameters of the sediment were analysed (granulometry, organic matter content, pH, bottom salinity and shelter availability. Nine different species and subspecies were identified, belonging to five families. Aspidosiphon muelleri muelleri was the dominant species, accumulating 89.06% of the total abundance of sipunculans. Higher sipunculan abundances were correlated with stations of higher percentage of coarse sand, empty mollusc shells and empty tubes of the serpulid polychaete Ditrupa arietina, where some of the recorded species live. Sediment characteristics played the main role controlling the sipunculans distribution. Anthropogenic impacts could be indirectly affecting their distribution, changing the sediment characteristics.

    Water quality characteristics and emerging organic pollutants were sampled along the San Pedro-Guayllabamba-Esmeraldas River and its main water pollution streams in the summer of 2013. The annual flow rate of the stream is 22 000 Mm(3) y(-1) and it collects the wastewater of Quito-Ecuador in the Andes and supplies drinking water to the city of Esmeraldas near the Pacific Ocean. The most persistent emerging pollutants were carbamazepine and acesulfame, which were found to be stable along the San Pedro-Guayllabamba-Esmeraldas River, whereas the concentration of most other organic emerging pollutants, such as caffeine, sulfamethoxazole, venlafaxine, O-desmethylvenlafaxine, and steroidal estrogens, was degraded to a large extent along the 300 km flow. The mass rate of the sum of cocaine and benzoylecgonine, its metabolite, was increased along the stream, which may be attributed to coca plantations and wild coca trees. This raises the possibility of using river monitoring as an indirect way to learn about changes in coca plantations in their watersheds. Several organic emerging pollutants, such as venlafaxine, carbamazepine, sulphamethoxazole, and benzoylecgonine, survived even the filtration treatment at the Esmeraldas drinking water system, though all except for benzoylecgonine are found below 20 ng L(-1), and are therefore not likely to cause adverse health effects. The research provides a way to compare drug consumption in a major Latin American city (Quito) and shows that the consumption of most sampled drugs (carbamazepine, venlafaxine, O-desmethylvenlafaxine, sulphamethoxazole, ethinylestradiol) was below their average consumption level in Europe, Israel, and North America.

    Contamination of surface waters in developing countries is a great concern. Treated and untreated wastewaters have been discharged into rivers and streams, leading to possible waterborne infection outbreaks and may represent a significant dissemination mechanism of antibiotic resistance genes. In this study, the water quality of San Pedro River, the main river and pluvial collector of the Aguascalientes State, Mexico was assessed. Thirty sample locations were tested throughout the River. The main physicochemical parameters of water were evaluated. Results showed high levels of fecal pollution as well as inorganic and organic matter abundant enough to support the heterotrophic growth of microorganisms. These results indicate poor water quality in samples from different locations. One hundred and fifty Escherichia coli were collected and screened by PCR for several virulence genes. Isolates were classified as either pathogenic (n = 91) or commensal (n = 59). The disc diffusion method was used to determine antimicrobial susceptibility to 13 antibiotics. Fifty-two percent of the isolates were resistant to at least one antimicrobial agent and 30.6% were multi-resistant. Eighteen E. coli strains were quinolone resistant of which 16 were multi-resistant. Plasmid-mediated quinolone resistance (PMQR) genes were detected in 12 isolates. Mutations at the Ser-83→Leu and/or Asp-87→Asn in the gyrA gene were detected as well as mutations at the Ser-80→Ile in parC. An E. coli microarray (Maxivirulence V 3.1) was used to characterize the virulence and antimicrobial resistance genes profiles of the fluoroquinolone-resistant isolates. Antimicrobial resistance genes such as bla TEM, sulI, sulII, dhfrIX, aph3 (strA), and tet (B) as well as integrons were found in fluoroquinolone (FQ) resistance E. coli strains. The presence of potential pathogenic E. coli and antibiotic resistance in San Pedro River such as FQ resistant E. coli could pose a potential threat to human and animal

The tuber powder exhibited a free amino acid profile being arginine (8.59 mg g-1 and glutamine (3.36 mg g-1 the most abundant. Feed consumption was not influenced by any treatment; however, the survival and the overall production responses were higher in both treatments using the powder (T1 and T2 compared to the control. No significant differences were detected in muscle concentrations of lactate and glucose, although higher protein and lower cholesterol concentrations were observed in shrimp reared in the control. The lower cholesterol concentration of shrimp from the control could be associated to a poor nutritional status. In conclusion, addition of the powder of San Pedro daisy did not improve the feed consumption, but apparently had a positive effect on survival, production response and nutritional status of shrimp. These responses could be associated to an hypothetic effect of some plant components at a nutritional-molecular level, or to a possible antimicrobial effect; however, further specific studies are needed.

    Subduction-related magmas that erupted in the Central Andes during the past 10 Ma are strongly affected by crustal assimilation as revealed by an increase in 87Sr/86Sr isotope ratios with time that in turn are correlated with increased crustal thickening during the Andean orogeny. However, contamination is not uniform and can be strongly influenced locally by crustal composition, structure and thermal condition. This appears to be the case along the NW-SE San Pedro - Linzor volcanic chain (SPLVC) in northern Chile, which straddles the boundary of a major zone of partial melt, the Altiplano_Puna Magma Body (APMB). Herein we report 40Ar/39Ar ages, compositional and isotope data on lavas from the SPLVC that track the influence of this zone of partial melting on erupted lavas with geochronological and geochemical data. Ages reported here indicate that SPLVC has evolved in the last 2 M.y., similar to other volcanoes of the Western Cordillera (e.g. Lascar, Uturuncu, Putana). 87Sr/86Sr ratios increase systematically along the chain from a minimum value of 0.7057 in San Pedro dacites to a maximum of 0.7093-0.7095 for the Toconce and Cerro de Leon dacites in the SE. These changes are interpreted to reflect the increasing interaction of SPLVC parental magmas with partial melt within the APMB eastwards across the chain. The 87Sr/86Sr ratio and an antithetic trend in 143Nd/144Nd is therefore a proxy for the contribution of melt from the APMB beneath this volcanic chain. Similar 87Sr/86Sr increases and 143Nd/144Nd decreases are observed in other transects crossing the boundary of the APMB. Such trends can be recognized from NW to SE between Aucanquilcha, Ollagüe, and Uturuncu volcanoes, and from Lascar volcano to the N-S-trending Putana-Sairecabur-Licancabur volcanic chain to the north. We interpret these isotopic trends as reflecting different degrees of interaction of mafic parental melts with the APMB. High 87Sr/86Sr, and low 143Nd/144Nd reveal zones where the APMB is

    Full Text Available In order to study the social perception and valorization that people of different social statuses and different cultural cities have about nature, an international cooperative project was started between Germany and Chile. Due to the comparative nature of the project, districts of upper-middle and lower-middle class neighborhoods in both countries were chosen. In Germany, two neighborhoods (Silberhöhe and Paulusviertel were chosen from the city of Halle whereas in Chile one neighborhood from the city of Talcahuano (Tumbes and the city of San Pedro de la Paz (both in the Region VIII, Biobío were selected. People from all four study areas were surveyed with the same questions. The results revealed a differential use and perception of the urban landscape by people of different social and cultural backgrounds. Likewise, in Chile a person’s social condition was found to determine the possibility of his/her access to green areas and recreational zones.

    Full Text Available The San Pedro Frio district mining, Colombia, is a rich region producing gold-silver ores. Nowadays, the extraction processes used are amalgamation, percolation cyanidation and precipitation with zinc wood. Due to the ignorance of the ore characteristics, gold and silver treatment processes are inadequate and not efficient In addition the inappropriate use of mercury and cyanide cause environmental contamination. In this research the ore characterization was carried out obtaining fundamental parameters for the technical selection of more efficient gold and silver extraction processes. Experimental work was addressed to the study of both processes the agitation cyanidation and the adsorption on activated carbon in pulp. As a final result proposed a flowsheet to improve the precious metals recovery and reduce the environment contamination.

    Full Text Available Contamination of surface waters in developing countries is a great concern. Treated and untreated wastewaters have been discharged into rivers and streams, leading to possible waterborne infection outbreaks and may represent a significant dissemination mechanism of antibiotic resistance genes. In this study, the water quality of San Pedro River, the main river and pluvial collector of the Aguascalientes State, Mexico was assessed. Thirty sample locations were tested throughout the River. The main physicochemical parameters of water were evaluated. Results showed high levels of fecal pollution as well as inorganic and organic matter abundant enough to support the heterotrophic growth of microorganisms. These results indicate poor water quality in samples from different locations. One hundred and fifty Escherichia coli were collected and screened by PCR for several virulence genes. Isolates were classified as either pathogenic (n = 91 or commensal (n = 59. The disc diffusion method was used to determine antimicrobial susceptibility to 13 antibiotics. Fifty-two percent of the isolates were resistant to at least one antimicrobial agent and 30.6% were multi-resistant. Eighteen E. coli strains were quinolone resistant of which 16 were multi-resistant. Plasmid-mediated quinolone resistance genes were detected in 12 isolates. Mutations at the Ser-83→Leu and/or Asp-87→Asn in the gyrA gene were detected as well as mutations at the Ser-80→Ile in parC. An E. coli microarray (Maxivirulence V 3.1 was used to characterize the virulence and antimicrobial resistance genes profiles of the fluoroquinolone-resistant isolates. Antimicrobial resistance genes such as blaTEM, sulI, sulII, dhfrIX, aph3 (strA and tet (B as well as integrons were found in fluoroquinolone resistance E. coli strains. The presence of potential pathogenic E. coli and antibiotic resistance in San Pedro River such as fluoroquinolone resistant E. coli could pose a potential threat to human

    This study is a coordinated effort by the U.S. Geological Survey (USGS), the U.S. Department of Agriculture, Agricultural Research Service (USDA ARS), and Arizona State University, with assistance from the U.S. Army Corps of Engineers, the University of Wyoming, and the University of Arizona. The specific objectives of the study were: to determine the water needs of riparian vegetation through the riparian growing season and throughout the SPRNCA to ensure its long-term ecological integrity; to quantify the total water use of riparian vegetation within the SPRNCA; and to determine the source of water used by key riparian plant species within the SPRNCA. To meet these objectives, the study was divided into three elements: (1) a characterization of the status and variability of hydrologic factors within the riparian system (USGS), (2) a riparian biohydrology study to relate spatial and temporal aspects of riparian changes and condition to the hydrologic variables (Arizona State University), and (3) a water-use evapotranspiration (ET) study to quantify annual consumptive ground-water use by riparian transpiration and direct evaporation from the stream channel (USDA ARS) in cooperation with the U.S. Army Corps of Engineers, the University of Wyoming, and the University of Arizona. Twenty-six sites within the SPRNCA were selected for collection of vegetation data from three primary streamflow regimes (perennial, intermittent-wet, intermittent-dry), which include the principal vegetation communities. Detailed hydrologic-condition data were collected at a subset of 16 of these sites, called the SPRNCA biohydrology sites. Water-use and water-source data were collected at a subset of 5 of the 16 biohydrology sites. Vegetation data also were collected at supplemental sites within the SPRNCA boundary in the Upper San Pedro Basin and in the Lower San Pedro Basin. In addition to information about vegetation and geomorphic conditions, hydrologic data collected at the 16

    Long-term land-use and land cover change and their associated impacts pose critical challenges to sustaining vital hydrological ecosystem services for future generations. In this study, a methodology to characterize hydrologic impacts from future urban growth through time that was developed and applied on the San Pedro River Basin was expanded and utilized on the South Platte River Basin as well. Future urban growth is represented by housing density maps generated in decadal intervals from 2010 to 2100, produced by the U.S. Environmental Protection Agency (EPA) Integrated Climate and Land-Use Scenarios (ICLUS) project. ICLUS developed future housing density maps by adapting the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) social, economic, and demographic storylines to the conterminous United States. To characterize hydrologic impacts from future growth, the housing density maps were reclassified to National Land Cover Database (NLCD) 2006 land cover classes and used to parameterize the Soil and Water Assessment Tool (SWAT) using the Automated Geospatial Watershed Assessment (AGWA) tool. The objectives of this project were to 1) develop and implement a methodology for adapting the ICLUS data for use in AGWA as an approach to evaluate impacts of development on water-quantity and -quality, 2) present, evaluate, and compare results from scenarios for watersheds in two different geographic and climatic regions, 3) determine watershed specific implications of this type of future land cover change analysis.

    The Upper San Pedro River is one of the few remaining undammed rivers that maintain a vibrant riparian ecosystem in the southwest United States. However, its riparian forest is threatened by diminishing groundwater and surface water inputs, due to either changes in watershed characteristics such as changes in riparian and upland vegetation, or human activities such as regional groundwater pumping. We used satellite vegetation indices to quantify the green leaf density of the groundwater-dependent riparian forest from 1984 to 2012. The river was divided into a southern, upstream (mainly perennial flow) reach and a northern, downstream (mainly intermittent and ephemeral flow) reach. Pre-monsoon (June) Landsat normalized difference vegetation index (NDVI) values showed a 20% drop for the northern reach (P  0·05). NDVI and enhanced vegetation index values were positively correlated (P factor in reducing river flows. Climate change, regional groundwater pumping, changes in the intensity of monsoon rain events and lack of overbank flooding are feasible explanations for deterioration of the riparian forest in the northern reach.

    A definition of the hydrologic system of the upper San Pedro basin was obtained by developing a numerical ground-water model to evaluate a conceptual model of the system. Information on hydraulic properties of the basin fill, recharge from bordering mountain ranges, discharge by evapotranspiration, and exchange of water between aquifer and stream was available from previous measurements or estimates. The steady-state calibration procedure and subsequent transient simulations demonstrated that the original conceptualization can be reasonably simulated. An analysis of model sensitivity to increases and decreases in certain hydraulic properties indicated a low sensitivity to aquifer anisotropy and a low to moderate sensitivity to stream leakance and evapotranspiration rate. An analysis to investigate the effects of generalizing aquifer conductivity and recharge showed that flow components and water-level response to stress could be simulated adequately but that steady-state water-level conditions could not. During equilibrium conditions, recharge to and discharge from the basin was about 16,500 acre-feet per year. Modeling results indicated that by 1978 the storage depletion rate had reached 5,600 acre-feet per year resulting from a ground-water withdrawal rate of 10,500 acre-feet per year. (USGS)

    Full Text Available The Sierra of San Pedro forms a Paleozoic synform, located in the southern part of the Central Iberian zone (Iberian Massif. The thickness of the Paleozoic sequence in the synform can be evaluated at 2,800-3,000 m. Its base is in general formed by a 5-40 m thick quartzite unit, equivalent to the Armorican Quartzite (Arenig, resting unconformable on the Precambrian. However, a discontinuous conglomerate level, attributed to the basal Arenig, can locally be found underlying the quartzite. Above the quartzite, the sequence is essentially compound of an alternation of predominantly quartzite, sandstone and slate units. This alternation allows the sequence to be subdivided into several distinct lithological units. Towards the top, carbonate and volcanic levels are found, interlayered in the predominantly terrigenous sequence. Most of the lithostratigraphical units have provided fairly abundant faunas and could therefore be dated. The paleontological evidence shows that the sequence is continuous from the Lower Ordovician to the Lower Carboniferous, with the exception of a probable hiatus comprising the Middle Devonian. Upper Carboniferous conglomerates and sandstones also occur in the area.El sinforme de la Sierra de San Pedro, situado en la parte meridional de la Zona Centroibérica, está formado por materiales paleozoicos cuyo contacto con los materiales precámbricos que le rodean es en clara discordancia angular.

    The U.S. Southwest and Mexico border region feature two prominent river basins, the Colorado and Rio Grande, and ecologically important sub-basins such as the San Pedro. The area within which these transboundary basins lie is characterized by overall aridity and high climatic variability over seasonal to decadal and longer time scales. Throughout human occupation, numerous and diverse strategies for buffering climate impacts have emerged. The most notable response has been an increasingly complex system of institutions and structures designed to buffer water scarcity. The Colorado River Compact, and the laws governing allocation of waters from the Rio Grande River, together with the dams, hydropower generators, canals and other engineered features, represent two of the most complex systems. Drought nevertheless remains a looming specter across much of the binational border region. Institutional mechanisms for responding to drought range from awareness-raising and capacity-building efforts, to implementation of formal drought plans, to storing water to make up for deficits, and water conservation rules that become increasingly stringent as drought intensifies. A number of formal and informal binational institutions operate in the region. Some are venerable, like the century-old International Boundary and Water Commission (IBWC) and its Mexican counterpart the Comision Internacional de Limites y Agua (CILA). Others, like the Border Environment Cooperation Commission and the North American Development Bank, were created in the mid-1990s with the North American Free Trade Agreement. These institutions, both domestic and transnational, operate in a complex binational, bicultural environment with contrasting legal and administrative traditions. Under such constraints, they manage water resources and ecosystems and attempt to improve water and sanitation infrastructure in the context of deep and extended drought. But in spite of their efforts, society and natural habitat

    The effects of solid organic wastes from a marine fish farm on sediments were tested using benthic community as ecological indicators and biomarkers in native clam (Scrobicularia plana) as biochemical indicators. The benthic fauna and clam samples were collected in the intertidal sediment in October 2010 from five sites of the Rio San Pedro (RSP) creek, following a gradient of contamination from the aquaculture effluent to the control site. Numbers of species, abundance, richness and Shannon diversity were the biodiversity indicators measured in benthic fauna. Morphological and reproduction status of clams were assessed using the condition factor and gonado-somatic index, respectively. Phase I and Phase II detoxification enzymatic activities (ethoxyresorufin O-deethylase (EROD), glutathione S-transferase (GST)), antioxidant enzymatic activities (glutathione peroxidase (GPX), glutathione reductase (GR)) and oxidative stress parameters (Lipid Peroxidation (LPO) and DNA strand breaks) were measured in clams' digestive gland tissues. In parallel, temperature and salinity in the adjacent water, redox potential, pH and organic matter in sediment, and dissolved oxygen in the interstitial water were measured. The results suggested that RSP showed a spatial gradient characterised by hypoxia/anoxia, reduced potential, acidic conditions and high organic enrichment in sediments at the most contaminated sites. Significant (pbiodiversity indicators were observed in the areas impacted by the aquaculture discharges. Biomarkers did not show a clear pattern and of all biochemical responses tested, GPX, DNA damage and LPO were the most sensitive ones and showed significant (ppolluted sites. Benthic biodiversity indicators were significantly (pchanges of the benthic population structure and health status of the exposed organisms.

    The Trans-Mexican Volcanic Belt (TMVB) is one of the largest continental volcanic arcs of the North American plate. It spans about 1000 km from the Pacific to the Gulf of Mexico. Despite the abundance of thick lava sequences with quite high extrusion rates, the TMVB have been relatively little studied from a paleomagnetic point of view. Previous studies were aimed for tectonic evolution of the region rather than documenting fluctuations of Earth's magnetic field in terms of both directions and intensity. We report a detailed paleomagnetic and rock-magnetic study of Tequila and Ceboruco-San Pedro-Amado Nervo volcanic fields. 350 oriented samples belonging to 31 independent cooling units were collected. All these sites were previously dated by means of the state-of-the-art 40Ar-39Ar geochronological method and span from 1.1 Ma to 2 Ky. Rock-magnetic experiments which included continuous susceptibility, isothermal remanence acquisition and hysteresis measurements point to simple magnetic mineralogy. In most of cases, the remanence is carried by Ti-poor titanomagnetite of pseudo-single-domain magnetic structure. The paleodirections of the flow dated as 819±25 ka correspond to a VGP latitude of 18° N. This anomalous field behaviour apparently recorded prior to the Matuyama-Brunhes reversal may coincide with the geomagnetic event, defined as M-B precursor. Two independent lava flows, dated as 623±91 and 614±16 ka respectively, yield reverse paleodirections and one lava flow dated as 690±29 yields transitional paleodirections. It is possible that these lavas erupted during the worldwide observable Big Lost or Delta events.

    The flash flood frequency analysis in mountainous catchments presents specific scientific challenges. One of the challenges is the relevant gradient in precipitation intensity with altitude. Another challenge is the lack of information from rainfall or discharge gauge stations or from documentary sources. Dendrogeomorphology studies the response in the wood growth pattern and the botanical signs on the trees affected by geomorphological processes. With regard to the flood frequency, the dendrogeomorphological evidences bring forward valuable infomation about single past events (with annual or even seasonal precision) and their occurrence periodicity. The main macro-evidence that we can find in the tree trunk is a stem scar originated by a wound in the bark of the tree. When the tree grows, this wound remains reflected in the tree ring sequence. The best way to analyze the tree ring sequence is by using a complete section of the trunk, this couldn't be possible unless the tree is cut down. Due to the unfeasibility of cutting down the trees, in Dendrogeomorphology is enough to obtain an increment core, using a Pressler borer. Nevertheless, this study has been based on complete stem sections analysis facilitated for the felling works in the riverine vegetation in the Arenal River, carried out by the Tagus River Water Authority. These felling works have allowed us to obtain sections and to analyze the stump of the tree in situ. On this way, 100 samples of Alnus glutinosa and Fraxinus angustifolia located by the river along the Arenal River crossing Arenas de San Pedro Village (Ávila, northern slopes of the Gredos Mountain Range in the Spanish Central System) have been analyzed. This village is known for its historical problems of flood during extreme events. A meticulous fieldwork has been carried out. Every sample was analyzed locating its geomorphological position, the distance to the riverbed and the height of the stump in which the evidences were observed. Using a

    Assessing the impact of climate change on large river basins in the southwestern United States is important given the natural water scarcity in the region. The bimodal distribution of annual precipitation also presents a challenge as differential climate impacts during the winter and summer seasons are not currently well understood. In this work, we focus on the hydrological consequences of climate change in the Santa Cruz and San Pedro river basins along the Arizona-Sonora border at high spatiotemporal resolutions (~100 m and ~1 hour). These river systems support rich ecological communities along riparian corridors that provide habitat to migratory birds and support recreational and economic activities. Determining the climate impacts on riparian communities involves assessing how river flows and groundwater recharge will change with altered temperature and precipitation regimes. In this study, we use a distributed hydrologic model, known as the TIN-based Real-time Integrated Basin Simulator (tRIBS), to generate simulated hydrological fields under historical (1991-2000) and climate change (2031-2040) scenarios obtained from an application of the Weather Research and Forecast (WRF) model. Using the distributed model, we transform the meteorological scenarios from WRF at 10-km, hourly resolution into predictions of the annual water budget, seasonal land surface fluxes and individual hydrographs of flood and recharge events. For this contribution, we selected two full years in the historical period and in the future scenario that represent wet and dry conditions for each decade. Given the size of the two basins, we rely on a high performance computing platform and a parallel domain discretization using sub-basin partitioning with higher resolutions maintained at experimental catchments in each river basin. Model simulations utilize best-available data across the Arizona-Sonora border on topography, land cover and soils obtained from analysis of remotely

    Hydrologic modeling using high spatiotemporal resolution satellite precipitation products in the southwestern United States and northwest Mexico is important given the sparse nature of available rain gauges. In addition, the bimodal distribution of annual precipitation also presents a challenge as differential climate impacts during the winter and summer seasons are not currently well understood. In this work, we focus on hydrological comparisons using rainfall forcing from a satellite-based product, downscaled GCM precipitation estimates and available ground observations. The simulations are being conducted in the Santa Cruz and San Pedro river basins along the Arizona-Sonora border at high spatiotemporal resolutions (~100 m and ~1 hour). We use a distributed hydrologic model, known as the TIN-based Real-time Integrated Basin Simulator (tRIBS), to generate simulated hydrological fields under historical (1991-2000) and climate change (2031-2040) scenarios obtained from an application of the Weather Research and Forecast (WRF) model. Using the distributed model, we transform the meteorological scenarios at 10-km, hourly resolution into predictions of the annual water budget, seasonal land surface fluxes and individual hydrographs of flood and recharge events.

    Full Text Available By means of environmental anthropology and ethnography, this article describes the formation of the institutionalized ecological identity of the “recuperaters” in Presidente Regional Landfill in San Pedro, Valle Department. It shows how environmental discourses, by ascribing identities to people who work in the landfill, obscure their roles. “Recuperators,” by contrast, openly discuss and think about the importance of their job. They have been forging an identity of resistance, or a political identity, through the social memory of enduring regressive policies, such as law 1259 of 2008, legally permitted by Colombia’s 1991 constitution. In this way, they propose alternatives, such as their social organization, to “struggle” for their right to recycle in the face of a growing interest by domestic and multinational companies in turning “garbage” into a business.

  4. Simulated effects of ground-water withdrawals and artificial recharge on discharge to streams, springs, and riparian vegetation in the Sierra Vista Subwatershed of the Upper San Pedro Basin, southeastern Arizona

    In the context of ground-water resources, “capture” or “streamflow depletion” refers to withdrawal-induced changes in inflow to or outflow from an aquifer. These concepts are helpful in understanding the effects of long-term development of ground-water resources. For the Upper San Pedro Basin in Arizona, USA and Sonora, Mexico, a recently developed ground-water flow model is available to help quantify capture of water from the river and riparian system. A common method of analysis is to compute curves of capture and aquifer-storage change for a range of time at select points of interest. This study, however, presents results of a method to show spatial distributions of total change in inflow and outflow from withdrawal or injection for select times of interest. The mapped areal distributions show the effect of a single well in terms of the ratio of the change in boundary flow rate to rate of withdrawal or injection by the well. To the extent that the system responds linearly to ground-water withdrawal or injection, fractional responses in the mapped distributions can be used to quantify response for any withdrawal or injection rate. Capture distributions calculated using the Upper San Pedro model include response to (1) withdrawal in the lower basin-fill aquifer for times of 10 and 50 years following the initiation of pumping from predevelopment conditions and (2) artificial recharge to the water table in the area underlain by the lower basin-fill aquifer after 10 and 50 years. The mapped distributions show that response to withdrawals and injections is greatest near the river/riparian system. Presence of clay layers in the vertical interval between withdrawal locations and the river/riparian system, however, can delay the response.

  5. Petrography, geochemistry and depositional setting of the San Pedro and Santo Tomas coal zones: anomalous algae-rich coals in the middle part of the Claiborne Group (Eocene) of Webb County, Texas

    Two coal zones, the San Pedro and the overlying Santo Tomas, are present for nearly 35 km along the strike of the middle part of the Claiborne Group (Eocene) in Webb County, Texas. A sandstone-dominated interval of 25 to 35 m separates the two coal zones, which range up to 3 m in thickness. Each coal zone contains carbonaceous shales, thin ({lt}0.75 m) impure coal beds, and thin ({lt}0.85 m) but commercially significant nonbanded coal beds. The coal-bearing portion of the middle Claiborne Group in the Rio Grande area represents a fining-upward transition from sandstone-dominated, marine-influenced, lower delta plain depositional environments to more inland, mudstone-rich, predominantly freshwater deltaic settings. Discontinuities within the San Pedro coal zone are attributed mainly to the influence of contemporaneous deposition of distributary mouth-bar sand bodies. The less variable nature of the Santo Tomas coal zone reflects its origin in the upper part of an interlobe basin that received only minor clastic influx. Petrographic attributes of the nonbanded coals indicate that they formed subaqueously in fresh to possibly brackish waters. A highly degraded groundmass composed of eugelinite is the main petrographic component (approximately 71%, mineral-matter-free basis). An enriched liptinite fraction (approximately 23%) probably accounts for unusually high calorific values. There is negligible inertinite. Petrographic study of polished blocks indicates that approximately 10% of the nonbanded coal from both coal zones is composed of green algae fructifications, which also occur in clastic rocks of the coal-bearing intervals. Such algal material cannot be identified or quantified by conventional coal petrographic techniques that utilize particle pellets or by palynological analyses that include acid preparation. 63 refs., 14 figs., 3 tabs.

    Full Text Available San-Pedro area is localized in south-western Côte d’Ivoire and covers a surface of 6912 km2. Wa t e r resources exploited in this area are constituted of surface waters and groundwater of weathered and fissured aquifers. The aims of this study are to analyze hydrodynamic properties of fissured aquifers of San-Pedro on statistical and geostatistical viewpoints for a better knowledge and management of groundwater resources. Data base includes 110 drillings tapping fissured aquifers. Transmissivity was calculated by interpreting of pumping tests with classical methods. Specific capacity was calculated at the end of the third step for all drillings after correction of drawdowns. Transmissivity and specific capacity values oscillate between 1,27.10-6 and 8,59.10-4 m2.s-1 and between 1,09.10-2 m2.h-1 et 13,2 m2.h-1, respectively. These two parameters span three orders of magnitude showing the strong heterogeneity of the medium. An empirical relationship was established between transmissivity and specific capacity of San-Pedro area. This relationship can be used to determine transmissivity in the sectors where this data is lacking. Variogram of transmissivity is characterized by a double structuring. Transmissivity assessment by kriging is satisfactory, observed and estimated values are comparable. The findings obtained in this study lead to a better understanding of hydrogeological properties of south-western Côte d’Ivoire.

    Full Text Available Para comprender la actual configuración paisajística de buena parte de la Costa del Sol Occidental hay que remontarse a finales del siglo XIX, cuando se creó la colonia agrícola de San Pedro Alcántara. Con ella surgió un modélico y moderno paisaje agrario, caracterizado por una extraordinaria diversidad de usos del suelo y un aprovechamiento sostenible de los recursos naturales en el marco de una organización que suponía importantes transformaciones ligadas al orden técnico y productivo. Sin embargo, la irrupción de la actividad turística a partir de los años 50 del siglo pasado supuso un cambio decisivo en las formas de vida tradicionales, vinculadas sobre todo a las actividades primarias, de tal manera que los paisajes coloniales de base agraria se fueron transformando paulatinamente en paisajes urbanos, totalmente desvinculados del mundo rural y en disonancia con el medio natural. En este trabajo trataremos de recuperar la memoria histórica del territorio que comprendía la colonia de San Pedro Alcántara a través del estudio de su paisaje, con el fin de no perder las raíces de los ciudadanos que lo habitan. Intentaremos conocer la magnitud de dichas mutaciones paisajísticas y provocar una reflexión sobre sus costes y beneficios. Para ello analizaremos las principales características del proceso de diversificación del paisaje a través de una interpretación geohistórica que abarca desde mediados del siglo XIX hasta mediados del XX. El estudio del medio físico, junto al análisis —a través de los planos catastrales— de los distintos modelos de organización productiva que han funcionado en esta finca, nos dará la clave de la ordenación última de este espacio y de la constitución de sus paisajes agrarios característicos.

    Full Text Available Escherichia coli shigatoxigénico (STEC produce enfermedades de transmisión alimentaria, desde diarreas leves a Síndrome Urémico Hemolítico, enfermedad de impacto en Argentina. Dentro de los alimentos implicados se destaca la carne bovina insuficientemente cocida. La contaminación de la carne molida y su relación con los estratos socioeconómicos no ha sido estudiada. El objetivo de este trabajo fue identificar en muestras de carne cepas STEC y establecer su perfil de virulencia, considerando la zona socioeconómica de procedencia y la persistencia de la contaminación en el local de venta. Se seleccionó el 30% de las bocas de expendio habilitadas en cada nivel socioeconómico. Se analizaron 72 muestras provenientes de 36 carnicerías de San Martín, Buenos Aires, en dos muestreos independientes utilizando PCR múltiple para stx1/stx2 e inmunocaptura para O157 al tamizaje. Se obtuvieron 11 cepas de 26 muestras sospechosas, 7% de los aislamientos fueron STEC O157. La proporción en la contaminación ponderada fue mayor en las zonas media y baja. No se comprobó persistencia. El grado de contaminación por STEC en carne para el área estudiada fue elevado y las cepas aisladas fueron altamente virulentas. En consideración a ello es necesario implementar programas de capacitación y control para reducir los riesgos para la salud pública.Shiga toxin-producing Escherichia coli (STEC causes foodborne diseases, from mild diarrhea to hemolytic uremic syndrome which impact in Argentina. Many human infections were acquired from eating undercooked contaminated beef. The contamination of ground beef and their relation to socio-economic strata has not been studied.

    As groundwater becomes an increasingly important water resource worldwide, it is essential to understand how local geology affects groundwater quality, flowpaths and residence times. This study utilized multiple tracers to improve conceptual and numerical models of groundwater flow in the Middle San Pedro Basin in southeastern Arizona (USA) by determining recharge areas, compartmentalization of water sources, flowpaths and residence times. Ninety-five groundwater and surface-water samples were analyzed for major ion chemistry (water type and Ca/Sr ratios) and stable (18O, 2H, 13C) and radiogenic (3H, 14C) isotopes, and resulting data were used in conjunction with hydrogeologic information (e.g. hydraulic head and hydrostratigraphy). Results show that recent recharge (recharged at high elevation in the fractured bedrock and has been extensively modified by water-rock reactions (increasing F and Sr, decreasing 14C) over long timescales (up to 35,000 years BP). Distinct solute and isotope geochemistries between the lower and upper basin fill aquifers show the importance of a clay confining unit on groundwater flow in the basin, which minimizes vertical groundwater movement.

    An integrated multi-trophic aquaculture assessment for Pacific oyster (Crassostrea gigas) aquaculture as a bioremediation strategy in areas impacted by fish farm effluents in Rio San Pedro was assessed by combining geographic information system with carrying capacity models. Sites of 0.44 km(2) were evaluated considering constraints; physical factors, growth and survival factors, environmental quality factors, water and sediment quality criteria, factor suitability ranges, and Multi-Criteria Evaluation. Isleta and Flamenco are promising sites for oyster production, and Dorada is of marginal interest. Carbon and nitrogen removal from the water by algae and through detritus filtration was estimated. The biodeposition of organic material from longline leases was found to have little negative impact on sediment. The eutrophication results indicate that phytoplankton removal had a positive impact on water quality at the Dorada. This case study quantified the direct profitability and bioremediative environmental service advantages that fish-shellfish farms can have relative to fish monocultures.

  13. Petrography, geochemistry, and depositional setting of the San Pedro and Santo Tomas coal zones: anomalous algae-rich coals in the middle part of the Claiborne Group (Eocene) of Webb County, Texas

    Two coal zones, the San Pedro and the overlying Santo Tomas, are presented for nearly 35 km in outcrop, surface and underground mines, and shallow drill holes along the strike of the middle part of the Claiborne Group (Eocene) in Webb County, Texas. A sandstone-dominated interval of 25 to 35 m separates the two coal zones, which range up to 3 m in thickness. The coal-bearing portion of the middle Claiborne Group in the Rio Grande area represents a fining-upward transition from sandstone-dominated, marine-influenced, lower delta plain depositional environments to more inland, mudstone-rich, predominantly freshwater deltaic settings. The less variable nature of the Santo Tomas coal zone reflects its origin in the upper part of an interlobe basin that received only minor clastic influx. Petrographic attributes of the nonbanded coals indicate that they formed subaqueously in fresh to possibly brackish waters. Petrographic study of polished blocks indicates that approximately 10% of the nonbanded coal from both coal zones is composed of green algae fructifications. -from Authors

If we consider those in which water resources play a significant role in carrying out agricultural activity, several different «water territories» can be identified in the Tiltil, Valle de Mallarauco and San Pedro de Melipilla areas. In these cases the study allowed us to shed light upon and discuss several important points regarding the territorial approach to water resources and water management in a model that favors the actions of private parties, such as: the extension of the agricultural use of the water resources, the conflicts and problems over its control and the resulting water territories that have come about as a result of the various assessments of a liberal management system. This has been done with the intention of contributing, from a Geographical point of view, thoughts geared towards achieving a comprehensive and sustainable management of the water resources in Chile.El espacio rural de la Región Metropolitana de Santiago de Chile es una combinación de factores naturales, sociales, económicos y técnicos que dan origen a diversos territorios.

Mediante la aplicación de la técnica etnográfica en la realización de la investigación de campo, se identificaron y localizaron a 30 personas adultas que aún entran a la laguna de Chimaliapan o Lerma, o que tienen conocimiento sobre los ingredientes lacustres y las preparaciones culinarias elaboradas con ellos. Además se realizaron visitas a los mercados locales e incursiones en la laguna y áreas aledañas con la guía de lugareños conocedores del entorno, con el fin de obtener información sobre estos productos. Se encontró que todavía se recolectan especies vegetales como nopales, hongos, papas de agua o apacloles y quelites, entre ellos berros o tiernitos y quintoniles. Asimismo, se aprovechan especies animales como patos, carpas, atepocates, ranas, acociles y ajolotes. Menos del 1% de la población estudiada aún elabora platillos basados en ingredientes extraídos de la laguna. Se preparan tamales de pescado, rana o carpa, acociles, hueva de carpa, carpas y patos de diversas maneras, chile relleno de támbulas y atepocates, y ranas empanizadas o fritas. Con base en lo anterior, se concluye, que a pesar de estar contaminada, todavía se extrae de la laguna de Chimaliapan una gran variedad de flora y fauna que se emplea para la alimentación, lo cual indica que estos recursos bióticos son una importante fuente para muchas familias, y que tienen un "buen potencial" de aprovechamiento.

El presente trabajo es la recopilación de los resultados de análisis y caracterización de minerales auroargentíferos de dicha zona minera. Con este artículo, se intenta incentivar a los mineros a realizar un desarrollo compaginado con la universidad, ya que según los resultados obtenidos durante esta investigación, es posible lograr porcentajes de disolución de oro de hasta el 85% para los minerales de San Pedro Frío. Esta afirmación fue posible proponerla, mediante los análisis de la caracterización del mineral. Mediante la caracterización fisicoquímica del mineral, fue posible la estimación de ciertas condiciones de los procesos metalúrgicos involucrados en una posible planta de tratamiento, es así que el porcentaje de sólidos más adecuado para el manejo de los sólidos en pulpa fue del 40% en peso, la alta cantidad de minerales arcillosos podrían dificultar los procesos de separación sólido-líquido, entre otros especificaciones operativas Según la caracterización mineralógica y metalúrgica, el tamaño promedio del oro presente en el mineral, se encuentra a una granulometría menor a 75 µm, esto indica que el proceso de cianuración por agitación resultaría el más adecuado. Los resultados de la lixiviación diagnóstico, arrogaron resultados muy satisfactorios, ya que el 94% del oro en las muestras se encuentra como oro libre, lo cual podrá incidir en tiempos cortos de cianuración.

    Full Text Available En este trabajo se evalúan los efectos de las modificaciones antrópicas sobre la recarga del acuífero freático en una zona medanosa. El caso de estudio es el área de San Clemente del Tuyú, en el litoral marítimo de la provincia de Buenos Aires, en donde el uso del suelo ha generado modificaciones significativas en el ciclo hidrológico. Se plantearon tres casos de distribución de uso del suelo, se elaboraron mapas isofreáticos para los años 1976, 1987, 2006 y se estimó el volumen de agua dulce disponible al momento de cada relevamiento. Esta información fue integrada a un Sistema de Información Geográfica (SIG. Los resultados obtenidos muestran que existe una relación directa entre la evolución del uso del suelo y la cantidad de agua subterránea almacenada. La zona de médano ha reducido su distribución areal en detrimento de las zonas con urbanización, ese comportamiento se corresponde con la disminución en los volúmenes de agua dulce almacenados para esa área. A modo de conclusión puede expresarse que las modificaciones en el uso del suelo a lo largo del tiempo se reflejan en el comportamiento del acuífero freático. Estudios de detalle recientes demuestran que la urbanización trae aparejada la disminución de las posibilidades de infiltración de los excesos de agua, restringiendo las áreas de recarga natural del acuífero y por consiguiente, las reservas de agua dulce disponibles. Por lo tanto se manifiesta la necesidad de fijar áreas protegidas como reserva y zona de recarga del acuífero con normas de ordenamiento territorial que contemplen la preservación de los mecanismos de recarga natural de las aguas subterráneas.The aim of this paper is to evaluate the effects of the anthropogenic modifications on the aquifer recharge in coastal dunes zones.

    Fast brightness variations are a unique tool to probe the innermost regions of active galactic nuclei (AGN). These variations are called microvariability or intra-night variability, and this phenomenon has been monitored in samples of blazars and unobscured AGNs. Detecting optical microvariations in targets hidden by the obscuring torus is a challenging task because the region responsible for the variations is hidden from our sight. However, there have been reports of fast variations in obscured Seyfert galaxies in X-rays, which rises the question whether microvariations can also be detected in obscured AGNs in the optical regime. Because the expected variations are very small and can easily be lost within the noise, the analysis requires a statistical approach. We report the use of a one-way analysis of variance, ANOVA, with which we searched for microvariability. ANOVA was successfully employed in previous studies of unobscured AGNs. As a result, we found microvariable events during three observing blocks: ...

    Full Text Available Se postula que los fenómenos de urbanización cerrada, en particular las de tipo acuáticas o polderizadas, en ámbitos caracterizados por el dominio de humedales en la cuenca baja del Río Luján, han ejercido profundas transformaciones ambientales sobre ecosistemas considerados estratégicos para el aglomerado metropolitano, al amparo de mecanismos de gestión del territorio caracterizados por algunos autores como propios del “urbanismo neoliberal”. Esto es apreciable en la desaprensión de los gobiernos locales y provinciales frente a las transformaciones del territorio y la degradación del ambiente, la vulneración de las normas –hidráulicas, urbanísticas y ambientales- que son de aplicación para este tipo de emprendimientos, y la generalización de una política de “hechos consumados”, sólo por citar algunos de los más salientes.En una primera parte,  la metodología da cuenta del proceso de construcción del objeto de estudio (urbanizaciones cerradas acuáticas y del universo de emprendimientos localizados en la cuenca, que totalizan 54 emprendimientos en una superficie de 7293 ha. En la segunda parte se analizan los procesos de gestión para un caso concreto: la Megaurbanización San Sebastián en el Partido de Pilar. La tercera parte del trabajo aborda las vulneraciones en que se incurre respecto al marco normativo y los procedimientos de aprobación aplicables, observando sus implicancias en la afectación del ecosistema de humedal y sus eventuales efectos en la relación de este megaemprendimiento con otros similares y con urbanizaciones preexistentes propias de la ciudad abierta.Los resultados se sistematizan en tablas y esquemas que muestran el incumplimiento de las normas y expresan la magnitud de las transformaciones territoriales, y se acompaña de cartografía general del área de estudio y de sector, que apoyan las conclusiones del trabajo.

    The Energy Information Administration (EIA) is the major collector of reliable and comprehensive data on energy supply and demand in this country. During its 16-year history, EIA has tried steadily to reduce the data-collection burden placed on business, industry, and the general public. Four years ago, EIA embarked on the creation of flexible, user-friendly, portable, state-of-the-art tool that would allow those petroleum companies that submit data to EIA to save time and money in the preparation and submission of their forms. This effort was undertaken in cooperation with the petroleum industry and resulted in the development of the Petroleum Electronic Data Reporting Option (PEDRO). Today, more than 20 forms are available for electronic filing. Further, the technology embodied in PEDRO has been adopted by other government agencies in various forms for their individual data collection systems.

    Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs).

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

    2000-01-01

    To celebrate the 60th anniversary of Medicina (Buenos Aires) an International Symposium was held at the National Academy of Medicine of Buenos Aires on the 6-7th of October 1999, under the title of Clinical investigation in the next millennium. This meeting was a success as evidenced by the 376 registered attendants. Sixty years of uninterrupted publication is an uncommon feat in our midst and this could be achieved on the basis of a number of factors which include, the initiative of those who founded the journal, the unfailing motivation and dedication of the Editorial Board and primarily the authors who have trusted us with their manuscripts. Of the many important papers published, we have selected a few which proved to be milestones in the development of Argentine biomedicine. It is to be hoped that the future will bring an increase in our impact index through more and even better papers eventually reflecting the authentic scientific value of our country.

    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.

    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

    Cholelithiasis is an important cause of morbidity in the world and it varies significantly depending on the region of study. To assess the prevalence of cholelithiasis in Buenos Aires. This is a cross-sectional, descriptive, observational study performed in a public hospital with tertiary care in Gastrointestinal Surgery. From July 2010 to December 2011, 1,875 healthy volunteers who underwent liver, gallbladder and pancreas ultrasound imaging were included and a questionnaire containing the individual's medical history was administered. The presence of cholelithiasis and its eventual risk factors were studied. Of 1,875 individuals, 866 were males (46.2%) and 1,009 females (53.8%), older than 20 years old with an average age of 46.1 + 16.7 years. Cholelithiasis was found in 410 inidviduals (21.9%); 285 (15.2%) diagnosed at the time of the study and 125 (67%) who had already undergone a cholecystectomy due to gallstones. The prevalence of cholelithiasis in Buenos Aires, capital city of Argentina, is 21.9%. A significant association was found between cholelithiasis and female gender, age, body mass index, history of colic pain, family history of cholelithiasis, smoking, fatty liver and number of pregnancies.

    Full Text Available Con el desarrollo industrial de la provincia, parcialmente promovido por la Corporación de Fomento, CORFO, desde el terremoto de 1939, y la construcción de la planta CAP-Huachipato en 1950, la CORVI buscó construir un conjunto para satisfacer la creciente necesidad habitacional. El terremoto de 1960 incorporó, indudablemente, una extrema urgencia al encargo. Por el particular entorno geográfico de la ciudad de Concepción, la institución se enfrentó a la escasez de terrenos baratos cercanos a Concepción, por lo que consideró un área perteneciente a la comuna de Coronel, pero, por su ubicación e importancia, era considerada como parte integrante de Concepción. Otro aspecto relevante es el fundamento o discurso político que incorporaba la Unidad Vecinal, seguramente fomentado por el terremoto político causado por la revolución cubana de 1959 y el remezón que produjo en la política de EE.UU. frente a los países latinoamericanos. Los arquitectos Raúl Farrú y Enrique Porte se encargaron del diseño de este particular proyecto habitacional que ofrecía 1.918 alojamientos, repartidos entre viviendas unifamiliares y departamentos. Con este proyecto, sea por el diseño arquitectónico y urbano, o por la política de selección de usuarios, la CORVI implementó una forma de crear una nueva ciudad, el paso inicial de un proyecto mayor. La permanencia, o sobrevivencia, de algunos servicios, como los colegios y algunos comercios, demostraron el logro y éxito de la propuesta de la CORVI, que iba mucho mas allá del diseño físico ya que incorporaba otra variante bastante más compleja como el uso o la función. Esta diversidad de funciones y actividades, en conjunto con la oferta habitacional, convirtieron, finalmente, este proyecto en una ciudad satélite prácticamente autónoma.

    2017-09-01

    This is a written version of the closing talk at the 22nd Los Alamos Stellar pulsation conference on wide field variability surveys. It comments on some of the issues which arise from the meeting. These include the need for attention to photometric standardization (especially in the infrared) and the somewhat controversial problem of statistical bias in the use of parallaxes (and other methods of distance determination). Some major advances in the use of pulsating variables to study Galactic structure are mentioned. The paper includes a clarification of apparently conflicting results from classical Cepheids and RR Lyrae stars in the inner Galaxy and bulge. The importance of understanding non-periodic phenomena in variable stars, particularly asymptotic giant branch variables and R Coronae Borealis stars, is stressed, especially for its relevance to mass-loss in which pulsation may only play a minor role.

Firstly the four wooden nave forms were sustituted by overdimensioned iron lattice girders that entered the aisles and ended in a capping hoop thus allowing the absorption of the pushes from the vaults that were ruining the church fabric. Besides a careful impermeabilization of both nave and aisles roof was undertaken. The second phase included the restoration of pases and sacristies roofs to their original configurations, both with a re-pointing of the tower's ashlers and a reopening of blinded windows in his intermediate volume. The ruined capping body made of bricks was substituted by another made of ashlers. New windows were designed according to the existent buttress and following the double arch configuration of the reopened ones.

    Las obras fueron realizadas en dos fases consecutivas. En la primera consistieron en sustituir las cuatro cerchas de madera de la nave central por estructuras metálicas de celosía sobredimensionadas que continuaban por las naves laterales y terminaban en zunchos de coronación, al objeto de absorber los empujes de las bóvedas que estaban arruinando la fábrica de la iglesia. Complemento de este trabajo fue una impermeabilización muy cuidada de las cubiertas de las tres naves. En la segunda fase se restituyeron las cubiertas de ábsides y sacristía a su configuración original, se rejuntaron los sillares de la torre, se abrieron los huecos que estaban cegados en su cuerpo intermedio y se sustituyó el cuerpo de ladrillo en ruinas de la coronación, por otro de sillería con los nuevos huecos dimensionados de acuerdo con los machones existentes y con el doble arco de las ventanas descubiertas.

    This paper is a part of a general research project on the role that chemistry played in the transition of materia medica to experimental pharmacology during 19th century Spain. Within this general framework, the paper deals with the main characteristics of Spanish textbooks aimed at pharmaceutical and medical students. In a former study, published in this journal, we outlined the institutional context in which these books were read, written and published. Some of these issues are developed in the present paper through analysis of the "Curso de química" written by Pedro Gutiérrez Bueno. New light is shed on the public for chemistry during the late XVIII century Spain and their role in shaping the contents and organisation of chemistry textbooks.

    2013-01-01

    In no other epoch of Western history like in the Middle Ages, cosmology was so key an element of culture and, one way or another, the motion of the heavens ended up impregnating the literature of that time. Among the most noteworthy poets we find Dante Alighieri, who became famous for his Commedia, a monumental poem written roughly between 1307 and his death in 1321, and which the critics from XVIth century onwards dubbed Divina. In this and other works, Dante pictures the cosmic image for the world, summing up the current trends of Neoplatonic and Islamic traditions. The Barolo Palace in the city of Buenos Aires is a singular combination of both astronomy and the worldview displayed in Dante's poetic masterpiece. Some links of the Palace's main architectural structure with the three realms of the Comedy have been studied in the past. In this note we consider its unique astronomical flavor, an issue which has not been sufficiently emphasized yet.

    BACKGROUND: It is unclear whether the Physiotherapy Evidence Database (PEDro) is widely and equally used by physical therapists in Brazil. As PEDro is considered a key resource to support evidence-based physical therapy, analyses of PEDro usage could reflect the extent of dissemination of evidence-based practice. OBJECTIVE: To describe the usage of PEDro among the five regions of the World Confederation for Physical Therapy (WCPT) and, in more detail, in the South American region and Brazil over a 5-year period. METHOD: PEDro home-page sessions and the number of searches performed were logged for a 5-year period (2010-2014). Absolute usage and relative usage were calculated for each region of the WCPT, each country in the South American region of WCPT, and each Regional Council (CREFITO) in Brazil. RESULTS: Europe had the highest absolute and relative usage among the five regions of the WCPT (971 searches per million-population per year), with the South American region ranked 4th in absolute terms and 3rd in relative terms (486). Within the South American region, Brazil accounted for nearly 60% of searches (755). Analysis at a national level revealed that usage per physical therapist in Brazil is very low across all CREFITOs. The highest usage occurred in CREFITO 6 with 1.3 searches per physical therapist per year. CONCLUSIONS: PEDro is not widely and equally used throughout Brazil. Strategies to promote PEDro and to make PEDro more accessible to physical therapists speaking Portuguese are needed. PMID:26443980

    Full Text Available AbstractIn order to get to know the habitat and feeding habits of Mugil liza on the southern coast of Buenos Aires province, 65 specimens obtained at two sampling sites - the San Blas bay (SBB and the mouth of the Quequén-Salado river (QSR - during spring (November 2012 and summer (February 2013 were analyzed. Specimens were measured, sexed and weighed, their stomachs were removed and their stomach contents weighed and analyzed under the stereoscopic microscope. The specimens were adults, 28-49 cm in length and weighing 380-1100 g. Population growth was higher in the SBB (TW: 0.003*TL3.36, than in RQS (TW: 0.045*TL2.61. About 98% of the stomachs had some content, their repletion rate being of between 0.4 and 1.2%. About 75% of the stomachs contained very fine sand with few benthic organisms (algae, copepods, foraminifera, whereas the remaining 25% of stomachs contained coarse sand and a greater presence of benthic fauna (amphipods, bivalves, gastropods and coral organisms. The linear relationship between the weight of stomach contents and the total weight and length of the fish showed that the rates of growth (slope were the same at both sites, but intercept values were significantly higher for San Blas bay (test parallelism; p < 0.001.

    To quantify the relationship between the number of times articles are accessed on the Physiotherapy Evidence Database (PEDro) and the article characteristics. A secondary aim was to examine the relationship between accesses and the number of citations of articles. The study was conducted to derive prediction models for the number of accesses of articles indexed on PEDro from factors that may influence an article's accesses. All articles available on PEDro from August 2014 to January 2015 were included. We extracted variables relating to the algorithm used to present PEDro search results (research design, year of publication, PEDro score, source of systematic review (Cochrane or non-Cochrane)) plus language, subdiscipline of physiotherapy, and whether articles were promoted to PEDro users. Three predictive models were examined using multiple regression analysis. Citation and journal impact factor were downloaded. There were 29,313 articles indexed in this period. We identified seven factors that predicted the number of accesses. More accesses were noted for factors related to the algorithm used to present PEDro search results (synthesis research (i.e., guidelines and reviews), recent articles, Cochrane reviews, and higher PEDro score) plus publication in English and being promoted to PEDro users. The musculoskeletal, neurology, orthopaedics, sports, and paediatrics subdisciplines were associated with more accesses. We also found that there was no association between number of accesses and citations. The number of times an article is accessed on PEDro is partly predicted by how condensed and high quality the evidence it contains is. Copyright © 2017 Chartered Society of Physiotherapy.

    Full Text Available En las primeras tres décadas del siglo XX, y al calor de los cambios urbanos que harían de Buenos Aires una metrópolis, la poesía, el cine, el teatro y las letras de tango trabajaron con insistencia la trayectoria protagonizada por la muchacha de barrio que, lanzándose al mundo de la noche y el cabaret del centro, apostaba a sacar ventajas de una sociedad donde el ascenso social, limitado pero real, era parte de la experiencia urbana. Las letras de tango, escritas mayoritariamente por hombres, hablan de ese viaje en clave de condena, y la tuberculosis aparece como la materialización de un castigo para esas mujeres jóvenes que han osado desafiar su lugar en el mundo doméstico y barrial. Así, el tango ofrece a su audiencia no sólo un registro fuertemente moralizante sino también la imagen de una enfermedad que parece ser exclusivo patrimonio femenino cuando, en realidad, se trataba de una enfermedad que afectaba tanto a hombres como a mujeres.

    Full Text Available There is debate on how the methodological quality of clinical trials should be assessed. We compared trials of physical therapy (PT judged to be of adequate quality based on summary scores from the Physiotherapy Evidence Database (PEDro scale with trials judged to be of adequate quality by Cochrane Risk of Bias criteria.Meta-epidemiological study within Cochrane Database of Systematic Reviews.Meta-analyses of PT trials were identified in the Cochrane Database of Systematic Reviews. For each trial PeDro and Cochrane assessments were extracted from the PeDro and Cochrane databases. Adequate quality was defined as adequate generation of random sequence, concealment of allocation, and blinding of outcome assessors (Cochrane criteria or as trials with a PEDro summary score ≥5 or ≥6 points. We combined trials of adequate quality using random-effects meta-analysis.Forty-one Cochrane reviews and 353 PT trials were included. All meta-analyses included trials with PEDro scores ≥5, 37 (90.2% included trials with PEDro scores ≥6 and only 22 (53.7% meta-analyses included trials of adequate quality according to the Cochrane criteria. Agreement between PeDro and Cochrane was poor for PeDro scores of ≥5 points (kappa = 0.12; 95% CI 0.07 to 0.16 and slight for ≥6 points (kappa 0.24; 95% CI 0.16-0.32. When combining effect sizes of trials deemed to be of adequate quality according to PEDro or Cochrane criteria, we found that a substantial difference in the combined effect size (≥0.15 was evident in 9 (22% out of the 41 meta-analyses for PEDro cutoff ≥5 and 10 (24% for cutoff ≥6.The PeDro and Cochrane approaches lead to different sets of trials of adequate quality, and different combined treatment estimates from meta-analyses of these trials. A consistent approach to assessing RoB in trials of physical therapy should be adopted.

    Andes virus is the causative agent of hantavirus pulmonary syndrome (HPS) in Argentina and neighboring countries. In our country four different areas are affected: Northwest, Southwest, Central and Northeast, where distinct Andes virus genotypes were characterized. Three genotypes were described in Buenos Aires province (Central area): AND-Buenos Aires, AND-Lechiguanas and AND-Plata. In this work, we considered all HPS cases confirmed by ELISA and real time RT-PCR during the period 2009-2014 in Buenos Aires province. The annual distribution, fatality rate and geographic distribution were analyzed. We also analyzed the genotypes involved by RT-PCR and nucleotide sequencing. Finally we evaluated epidemiological data in order to establish the route of transmission. We analyzed 1386 suspect cases of hantavirus infection from Buenos Aires province and we confirmed 88 cases of Hantavirus Pulmonary Syndrome during 2009-2014. The overall average was 14.3 cases per year. The occurrence of a HPS outbreak was confirmed in Buenos Aires province during 2013, showing a 3 fold increase in case number compared to the annual average between 2009 and 2012, tending to normalize during 2014. The overall lethality was 25.6%, with a maximum value of 45.5% in 2011. Genotype analysis was performed in 30.7% of confirmed cases, AND-BsAs show the highest incidence, it was characterized in 72% of the studied cases. Epidemiological data and results of viral genome comparison strongly suggest person-to-person transmission in the three clusters of two cases described in our study.

    Tropospheric ozone (O3T) is a secondary pollutant whose formation involved primarily solar radiation, NOx and volatile organic compounds. The North of the Buenos Aires Province has great agricultural-industrial activity; therefore, O3T study is an important issue in the area. In this paper, we present the first results tend to estimate and characterize O3T in San Nicol\\'as de los Arroyos, North of Buenos Aires. Due to a lack of in situ data, we analyse the observations of the instrument OMI (Ozone Monitoring Instrument) of land remote sensing satellite AURA (GSFC/NASA). The data cover the years 2004-2013. Applying the multitaper technique (MTM), very suitable for short and noisy data series, spectral analysis is performed on a grid corresponding 1{\\deg} in latitude by 1.5{\\deg} in longitude, centred South of the Province of Santa Fe. The most remarkable result is the emergence of a significant peak (95%) of four months cycle. To test the validity of this signal in San Nicol\\'as, daily solar radiation data (Q)...

    Full Text Available Performance and theater are two art forms that have had a long relationship of contradictions, animosity, confluences. But when studying them it is clear that they have always been linked. The boldest artists or the ones more eager to investigate disregard all the criticism and venture into that intermingling road that is highly productive and enriches the scene. In this paper we address this issue with examples from the theater in Buenos Aires.

    Full Text Available Intrauterine seizure is a rare event. Genetic predisposition and trauma are possible risk factors. OBJECTIVE: To review and comment on the historical description of intrauterine events of a bastard daughter of Dom Pedro I (Maria Isabel Alcântara Brasileira - 1830-1896. METHOD: Review of historical facts about the health of Dom Pedro I's daughter according to primary and secondary historical data. RESULTS: According to historical accounts, Dom Pedro I's daughter suffered trauma during the intrauterine period that provoked intrauterine seizures. At the age of eight years, she developed self-limited and benign generalized epilepsy. Like her father, she had mood problems and also learning difficulties. CONCLUSION: Dona Maria Isabel's own report does not shown sufficient evidence to support the diagnosis of post-traumatic intrauterine seizures. Nevertheless, her family history suggests a genetic basis for her epilepsy.A convulsão intra-uterina é evento raro, sendo possíveis fatores de risco a genética e o traumatismo. OBJETIVO: Rever e comentar a descrição histórica de eventos intra-uterinas de uma filha bastarda de D. Pedro I (Maria Isabel Alcântara Brasileira - 1830-1896. MÉTODO: Revisão dos fatos históricos sobre a saúde da filha do D. Pedro I, de acordo com dados históricos primários e secundários. RESULTADOS: A filha de Dom Pedro I, de acordo com relatos históricos teria sofrido um traumatismo durante o período intra-uterino, o que provocou convulsões intra-uterinas. Na idade de oito anos a menina desenvolveu uma epilepsia generalizada limitada e benigna. Como seu pai, teve problemas do humor e, também, dificuldades de aprendizagem. CONCLUSÃO: O relato de Dona Maria Isabel não gera prova suficiente para sustentar o diagnóstico de convulsões intra-uterinas de origem traumática. Não obstante, seus antecedentes familiares sugerem uma base genética para sua epilepsia.

    Full Text Available INTRODUCTION: Dom Pedro II, the Prince Heir and Emperor under regency, in a delicate period of the construction of the Brazilian nation, had convulsive seizures. OBJECTIVE: To investigate the convulsive seizures and related syndromes of Dom Pedro II and his family, besides the physicians in charge of the health care. METHOD: Narrative review based on primary and secondary sources. CONCLUSION: The scattered and self-limited convulsive seizures associated with physical and mental integrity favored a benign prognosis. Dom Pedro and his family presented rich history of epileptic seizures and febrile convulsion. This variety resembles the diagnosis of generalized epilepsy with febrile seizures plus that seems to be a combination of several syndromes with shared genetic susceptibility.INTRODUÇÃO: Dom Pedro, o príncipe herdeiro e imperador sob regência, em período delicado da formação da nação brasileira, apresentou crises convulsivas que geraram preocupação para o país.

MÉTODO: Revisão narrativa baseada em fontes primárias e secundárias. CONCLUSÃO: As crises convulsivas esparsas e auto-limitadas associadas a higidez física e mental de Dom Pedro II sugerem um prognóstico benigno. A história de epilepsia idiopática e convulsões febris no imperador e em outros membros da sua família aponta para o diagnóstico mais provável de Epilepsia Generalizada com Convulsões Febris Plus que é determinada por uma combinação de alguns tipos de manifestações epilépticas com suscetibilidade genética compartilhada.

  16. OBLIQUE WAYS OF TRANSCENDENCE: ASPECTS OF IDEALISM IN AUGUSTO DOS ANJOS AND PEDRO KILKERRY

    Directory of Open Access Journals (Sweden)

    Fabiano Rodrigo da Silva Santos

    2015-07-01

    Full Text Available This essay analyzes the manifestations of the idealism of romantic orientation in the poetry of Augusto dos Anjos and Pedro Kilkerry, showing the points of contact between their oeuvres and demonstrating that many of the innovative aesthetic procedures of their poetry appear as a reaction to urgencies of an idealistic conception of poetry. Augusto dos Anjos and Pedro Kilkerry attest the anxiety of apprehension of connections with a super-sensible sphere in phenomenal reality. Although this takes a different form in each of the poets, it can refer to a common poetic ideal that transcends the concrete reality. To accomplish this, they use aesthetic procedures that modernize the language of the romantic sublime – Augusto dos Anjos uses a hybrid philosophical repertoire that marks his poetry with a tense and innovative prosaic language, and Pedro Kilkerry opts for the indirect representation, made by an evocative and metonymic language, that evidences the mystery of the transcendent ideal without deciphering it.

  17. Role of the offshore Pedro Banks left-lateral strike-slip fault zone in the plate tectonic evolution of the northern Caribbean

    Science.gov (United States)

    Ott, B.; Mann, P.; Saunders, M.

    2013-12-01

    Previous workers, mainly mapping onland active faults on Caribbean islands, defined the northern Caribbean plate boundary zone as a 200-km-wide bounded by two active and parallel strike-slip faults: the Oriente fault along the northern edge of the Cayman trough with a GPS rate of 14 mm/yr, and and the Enriquillo-Plaintain Garden fault zone (EPGFZ) with a rate of 5-7 mm/yr. In this study we use 5,000 km of industry and academic data from the Nicaraguan Rise south and southwest of the EPGFZ in the maritime areas of Jamaica, Honduras, and Colombia to define an offshore, 700-km-long, active, left-lateral strike-slip fault in what has previously been considered the stable interior of the Caribbean plate as determined from plate-wide GPS studies. The fault was named by previous workers as the Pedro Banks fault zone because a 100-km-long segment of the fault forms an escarpment along the Pedro carbonate bank of the Nicaraguan Rise. Two fault segments of the PBFZ are defined: the 400-km-long eastern segment that exhibits large negative flower structures 10-50 km in width, with faults segments rupturing the sea floor as defined by high resolution 2D seismic data, and a 300-km-long western segment that is defined by a narrow zone of anomalous seismicity first observed by previous workers. The western end of the PBFZ terminates on a Quaternary rift structure, the San Andres rift, associated with Plio-Pleistocene volcanism and thickening trends indicating initial rifting in the Late Miocene. The southern end of the San Andreas rift terminates on the western Hess fault which also exhibits active strands consistent with left-lateral, strike-slip faults. The total length of the PBFZ-San Andres rift-Southern Hess escarpment fault is 1,200 km and traverses the entire western end of the Caribbean plate. Our interpretation is similar to previous models that have proposed the "stable" western Caribbean plate is broken by this fault whose rate of displacement is less than the threshold

    Full Text Available We present medical issues related to Dom Pedro de Alcântara Bragança e Bourbon (1798-1834, first Emperor of Brazil. This is made by means of narrative revision on historical facts starting from primary and secondary sources. Dom Pedro presented familiar incidence of epilepsy. His seizures were relatively benign and scattered, supposedly started at the age of 13: idiophatic epilepsy with generalized tonic-clonic seizures only or juvenile myoclonic epilepsy. He also had behavioral disorder characterized by hypersexuality, agitation and impulsiveness. It could have facilitated his opportunistic behavior necessary of daring to transgress the conservatism of the Portuguese crown, to create the constitutional monarchism in Brazil and in Portugal.Apresentamos aspectos médicos relacionadas a Dom Pedro de Alcântara Bragança e Bourbon (1798-1834, primeiro Imperador do Brasil. Isso é feito por meio de revisão narrativa sobre fatos históricos baseados em fontes primárias ou secundárias. Dom Pedro apresentou epilepsia de incidência familiar. Suas crises eram relativamente benignas e esparsas, de início provavelmente aos 13 anos: epilepsia idiopática generalizada com crises tônico-clônicas apenas ou epilepsia mioclônica juvenil. Ele também tinha transtorno do comportamento caracterizado por hipersexualidade, agitação e impulsividade. Isso pode ter facilitado seu comportamento oportunístico necessário para ousar a transgredir o conservadorismo da coroa portuguesa e criar o monarquismo constitucional no Brasil e em Portugal.

    Full Text Available El estudio de los efectos de la pobreza sobre el desempeño cognitivo durante las primeras fases del desarrollo, ha sido efectuado predominantemente en base a la definición de pobreza según el ingreso y el uso de paradigmas de inteligencia basados en la hipótesis de un factor general de funcionamiento cognitivo. En el presente trabajo se utilizó el concepto de Necesidades Básicas Insatisfechas (NBI como criterio de pobreza y se aplicó un paradigma cognitivo de funcionamiento ejecutivo proveniente de la Neurociencia. El mismo plantea el análisis de componentes de comportamientos inteligentes orientados hacia objetivos y asociados a la activación de circuitos cerebrales que involucran centralmente a la región prefrontal. Se comparó el desempeño ejecutivo de 247 niños escolarizados de 3 a 5 años de edad, provenientes de hogares pobres (NBI y no pobres o con Necesidades Básicas Satisfechas (NBS, y de jardines de infantes del Distrito Escolar 4 de la Ciudad de Buenos Aires (Boca-Barracas y de distritos escolares de Vicente López y San Isidro del Gran Buenos Aires (Argentina. Se administró una batería de pruebas que evalúan componentes de flexibilidad cognitiva, logro de objetivos y control atencional. Los resultados obtenidos muestran perfiles de desempeño diferentes entre ambos grupos. El perfil de desempeño menos eficiente en términos de las variables estudiadas se observó en el grupo de niños proveniente de hogares pobres. Estos resultados constituyen un aporte significativo de un paradigma neurocientífico para la implementación de estrategias de intervención orientadas a estimular el funcionamiento cognitivo de tipo ejecutivo de niños de edad preescolar.

  13. Influence of San Gabriel submarine canyon on narrow-shelf sediment dynamics, southern California

    Science.gov (United States)

    Karl, Herman A.

    1980-01-01

    Variations in the concentration of total suspended particulate matter (TSM) collected 1 m above bottom, changes in vertical profiles of light transmission, and substrate textural patterns reveal a corridor for preferential sediment transport on San Pedro continental shelf, California. During the winter, this corridor, designated the preferential transport corridor (PTC), is defined by higher concentrations of TSM relative to the rest of the shelf and extends for 10-15 km from the inner shelf to the head of San Gabriel Submarine Canyon. Vertical profiles of light transmission within the PTC suggest density stratification throughout the water column and apparent mixing in the upper 15-20 m of water column on either side of the PTC. The PTC is not as fully developed during the summer. Excursions in isopleths of substrate textural variables perpendicular to isobaths in the PTC suggest that although the PTC is seasonally episodic, it recurs regularly over a longer period.

    2016-01-01

    The shallow-sea hydrothermal vents at White Point (WP) in Palos Verdes on the southern California coast support microbial mats and provide easily accessed settings in which to study chemolithoautotrophic sulfur cycling. Previous studies have cultured sulfur-oxidizing bacteria from the WP mats; however, almost nothing is known about the in situ diversity and activity of the microorganisms in these habitats. We studied the diversity, micron-scale spatial associations and metabolic activity of the mat community via sequence analysis of 16S rRNA and aprA genes, fluorescence in situ hybridization (FISH) microscopy and sulfate reduction rate (SRR) measurements. Sequence analysis revealed a diverse group of bacteria, dominated by sulfur cycling gamma-, epsilon-, and deltaproteobacterial lineages such as Marithrix, Sulfurovum, and Desulfuromusa. FISH microscopy suggests a close physical association between sulfur-oxidizing and sulfur-reducing genotypes, while radiotracer studies showed low, but detectable, SRR. Comparative 16S rRNA gene sequence analyses indicate the WP sulfur vent microbial mat community is similar, but distinct from other hydrothermal vent communities representing a range of biotopes and lithologic settings. These findings suggest a complete biological sulfur cycle is operating in the WP mat ecosystem mediated by diverse bacterial lineages, with some similarity with deep-sea hydrothermal vent communities.

    Clinicians must be able to search effectively for relevant research if they are to provide evidence-based healthcare. It is therefore relevant to consider how users search databases of evidence in healthcare, including what information users look for and what search strategies they employ. To date such analyses have been restricted to the PubMed database. Although the Physiotherapy Evidence Database (PEDro) is searched millions of times each year, no studies have investigated how users search PEDro. To assess the content and quality of searches conducted on PEDro. Searches conducted on the PEDro website over 6 months were downloaded and the 'get' commands and page-views extracted. The following data were tabulated: the 25 most common searches; the number of search terms used; the frequency of use of simple and advanced searches, including the use of each advanced search field; and the frequency of use of various search strategies. Between August 2014 and January 2015, 893,971 search commands were entered on PEDro. Fewer than 18 % of these searches used the advanced search features of PEDro. 'Musculoskeletal' was the most common subdiscipline searched, while 'low back pain' was the most common individual search. Around 20 % of all searches contained errors. PEDro is a commonly used evidence resource, but searching appears to be sub-optimal in many cases. The effectiveness of searches conducted by users needs to improve, which could be facilitated by methods such as targeted training and amending the search interface.

Puesto que algunas pueden afectar al hombre, esa información es de utilidad para decidir la necesidad de implementar medidas de control, cuáles y con qué estrategia. Se estudió una muestra de 66 perros que concurrieron a ese Centro para su atención. Sus heces fueron analizadas según las técnicas de sedimentación modificada de Telemann y de flotación de Bembrook. Se halló un 40,9% de caninos parasitados, una cuarta parte de los cuales tenía más de una especie de parásito. Trichuris spp. y Ancylostoma spp fueron los géneros más comúnmente encontrados. La edad resultó una característica relacionada con las enteroparasitosis ya que los menores de 2 años presentaron una prevalencia significativamente mayor que el resto de los animales (77% y 28% respectivamente. La información sobre estas parasitosis y las medidas para controlarlas deberían incluirse en la comunicación en salud, destinada a la promoción de la tenencia responsable, que llevan a cabo los Centros de Zoonosis.To appreciate the magnitude of the problem of intestinal parasites in dogs with owners, prevalence was estimated in those dogs taken to the Zoonosis Center of the San Martin District, Buenos Aires Province, Argentine Republic.

  6. Identifying active interplate and intraplate fault zones in the western Caribbean plate from seismic reflection data and the significance of the Pedro Bank fault zone in the tectonic history of the Nicaraguan Rise

    The offshore Nicaraguan Rise in the western Caribbean Sea is an approximately 500,000 km2 area of Precambrian to Late Cretaceous tectonic terranes that have been assembled during the Late Cretaceous formation of the Caribbean plate and include: 1) the Chortis block, a continental fragment; 2) the Great Arc of the Caribbean, a deformed Cretaceous arc, and 3) the Caribbean large igneous province formed in late Cretaceous time. Middle Eocene to Recent eastward motion of the Caribbean plate has been largely controlled by strike-slip faulting along the northern Caribbean plate boundary zone that bounds the northern margin of the Nicaraguan Rise. These faults reactivate older rift structures near the island of Jamaica and form the transtensional basins of the Honduran Borderlands near Honduras. Recent GPS studies suggest that small amount of intraplate motion within the current margin of error of GPS measurements (1-3 mm/yr) may occur within the center of the western Caribbean plate at the Pedro Bank fault zone and Hess Escarpment. This study uses a database of over 54,000 km of modern and vintage 2D seismic data, combined with earthquake data and results from previous GPS studies to define the active areas of inter- and intraplate fault zones in the western Caribbean. Intraplate deformation occurs along the 700-km-long Pedro Bank fault zone that traverses the center of the Nicaraguan Rise and reactivates the paleo suture zone between the Great Arc of the Caribbean and the Caribbean large igneous province. The Pedro Bank fault zone also drives active extension at the 200-km-long San Andres rift along the southwest margin of the Nicaraguan Rise. Influence of the Cocos Ridge indentor may be contributing to reactivation of faulting along the southwesternmost, active segment of the Hess Escarpment.

    In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species. The information gathered revealed that 47% of the patients were under 18 years of age and had eaten basidiomes; the remaining 53% were adults who insisted that they were able to distinguish edible from toxic mushrooms. Chlorophyllum molybdites turned out to be the main cause of fungal intoxication in Buenos Aires, which is commonly confused with Macrolepiota procera, an edible mushroom. In the second place Amanita phalloides was registered, an agaric known to cause severe symptoms after a long period of latency (6-10 hours), and which can lead to hepatic failure even requiring a transplant to prevent severe internal injuries or even death, is not early and correctly treated.

    Buenos Aires, the capital city of Argentina, is surrounded by 24 neighboring districts forming the so-called Buenos Aires metropolitan area (AMBA) that holds a population of 14 million people. In this work, the atmospheric aerosol of this metropolitan area was characterized through the determination of mass concentration, black carbon and elemental concentrations, on PM10 and PM2.5 samples taken using a 'Gent' sampler. The sampling site was located at an urban area characterized by fast and heavy traffic and samples were collected each third day, along 24 hours, between October 2005 and February 2006. A number of elements (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Na, Rb, Sb, Sc, Se, Sm, Th, Yb and Zn) were determined by Neutron Activation Analysis and their results, as well as those of gravimetric mass concentrations, were compared with historical data. Enrichment factors were calculated for both fractions, using Sc as reference element and Mason's crustal concentration values, showing enrichment for As, Br, Sb, Se and Zn. Although the number of analyzed filters is still small, a preliminary factor analysis was run on both fraction results and different source profiles were found. The attribution of the sources to soil, high temperature processes including refuse incineration, fuel combustion and others, metal processes, traffic and other anthropogenic ones is discussed.

    The large variability in size and structure between playing positions in rugby merits specific kinanthropometric profiling. We aim to report detailed descriptive anthropometric data of a sample of 133 rugby players stratified by field positions (age 24.3 +/- 3.6 years, body mass 89.5 +/- 13.2 kg, and stature 178.8 +/- 7.3 cm) belonging to seven Group I teams competing in the Buenos Aires Rugby Union, and to find out if front row forwards (FR) have larger muscle and skeletal parameters. Body composition was analysed with the five-way fractionation method, expressing tissue masses in absolute terms, relative to weight as percentages and to stature as phantom z-scores. Furthermore, somatotype, body mass index, sum of six skinfolds, and muscle-to-bone ratio were calculated. Players were subsequently grouped into three positional clusters and muscular-skeletal elements compared, showing FR to have larger proportional muscle and skeletal structure than remaining forwards and backs (P < 0.001), albeit a similar muscle-to-bone ratio (P = 0.060). When compared to a sample of the top six teams at the 2003 Rugby World Cup, the Buenos Aires players were considerably smaller, measuring, on average, 3-11 cm less in height and 6-13 kg less in weight.

    In the first decades of the 20th century, Freud was known and quoted in Latin America by an elite of enlightened minds. In the 1940s a convergence took place in Buenos Aires of European exiles with local pioneers, and thus the Argentine Psychoanalytical Association was founded in 1942. Since then psychoanalysis has grown steadily and has spread into hospitals and universities, influencing culture at large. The socioeconomic situation of that time permitted this phenomenon to develop, to the astonishment of observers. In this paper the authors study the strong influence of Kleinian thought during the first 30 years of this development. The original works of local thinkers constitute the intellectual capital that sustains the idea of an 'Argentine psychoanalytic school'. During the 1970s, both society and psychoanalysis endured deep and complex changes. Lacan's teachings gained support and Klein's influence began to decline. At present the Buenos Aires Kleinians keep working, while their relationship with Lacanians and other schools is calmer. Respectful discussions became thus possible, oriented to strictly scientific differences.

    IntroductionThe Alazán, Apache, Martínez, and San Pedro Creeks in San Antonio, Texas, are part of a network of urban tributaries to the San Antonio River, known locally as the Westside Creeks. The Westside Creeks flow through some of the oldest neighborhoods in San Antonio. The disruption of streambed sediment is anticipated during a planned restoration to improve and restore the environmental condition of 14 miles of channelized sections of the Westside Creeks in San Antonio. These construction activities can create the potential to reintroduce chemicals found in the sediments into the ecosystem where, depending on hydrologic and environmental conditions, they could become bioavailable and toxic to aquatic life. Elevated concentrations of sediment-associated contaminants often are measured in urban areas such as San Antonio, Tex. Contaminants found in sediment can affect the health of aquatic organisms that ingest sediment. The gradual accumulation of trace elements and organic compounds in aquatic organisms can cause various physiological issues and can ultimately result in death of the aquatic organisms; in addition, subsequent ingestion of aquatic organisms can transfer the accumulated contaminants upward through the food chain (a process called biomagnification).The U.S. Geological Survey, in cooperation with the San Antonio River Authority, collected sediment samples and water samples for toxicity testing from sites on the Westside Creeks as part of an initial characterization of selected contaminants in the study area. Samples were collected in January 2014 during base-flow conditions and again in May 2104 after a period of stormwater runoff (poststorm conditions). Sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, brominated flame retardants, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). In addition, as an indicator of ecological health (and

The documents cover the period from the sixteenth to nineteenth century and provide information about the patrimony of the house, its social position and the political activities of Pedro Ventura de Puga during the firts half of the nineteenth century. The first part is focused on the origin and evolution of patrimony, way of living, nobility abuses (including social and sexual aspects, and the difficulties to keep the social status. In the second part, Pedro Ventura plays the main role: his participation in the War of Independence and the building of the liberal state. He is a relevant character to undestand the adaptation of nobility to an age of political changes and social ad economical survivals. The defense of the constitution and his participation in the liberal regime is compatible with the maintenance of a economy based on the collection of taxes and nobility titles. Pedro Ventura is politically registered as a moderate liberalist.

    Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas, known locally as the Westside Creeks (Alazán, Apache, Martínez, and San Pedro Creeks) and from the San Antonio River. Samples were collected during base flow and after periods of stormwater runoff (poststorm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides, polychlorinated biphenyls (PCBs), brominated flame retardants, and polycyclic aromatic hydrocarbons (PAHs). Potential risks of contaminants in sediment were evaluated by comparing concentrations of contaminants in sediment to two effects-based sediment-quality guidelines: (1) a lower level, called the threshold effect concentration, below which, harmful effects to benthic biota are not expected, and (2) a higher level, the probable effect concentration (PEC), above which harmful effects are expected to occur frequently. Samples for water-toxicity testing were collected from each stream to provide information about fish toxicity in the study area. The trace metal lead was detected at potentially toxic concentrations greater than the PEC in both the base-flow and poststorm samples collected at two sites sampled on San Pedro Creek. The PECs for the pesticides dichlorodiphenyldichloroethane, dichlorodiphenyldichloroethylene, dichlorodiphenyltrichloroethane, and chlordane were exceeded in some of the samples at the same two sites on San Pedro Creek. Brominated flame retardants and polybrominated diphenyl ether (PBDE) 85, 153, and 154 were found in all streambed-sediment samples. Federal Environmental Quality Guidelines established by Environment Canada for PBDE 99 and PBDE 100 were exceeded in all samples in which PBDE 99 was detected and in a majority of the samples in which PBDE 100 was detected; the greatest concentrations

    Full Text Available Melancholy is an emotion that has been in fashion from the Renaissance until now. During the Enlightenment, human reason was accompanied by strong feelings preparing for Romanticism. A prominent personality in this field was Pedro Gatell, naval surgeon and untiring writer. Throughout his novels and moral writings he shows the main developments coming from the experience of melancholy and its interpretation.La melancolía es una emoción de moda desde el Renacimiento hasta hoy, también en la Ilustración la razón se vio acompañada de fuertes sentimientos que anunciaban el Romanticismo. Personaje destacado en este terreno es Pedro Gatell, cirujano naval e infatigable escritor.

    Full Text Available Atrazine persistence in soils of the southeast of Buenos Aires Province, was studied by an oat bioassay. Atrazine doses of 0.58, 1.16, and 2.32 mg.g-1 dry soil weight (DSW were applied to pots containing soils from Balcaree, A. Gonzáles Chaves and San Cayetano sites, whose organic matter (OM content of soils were 5.70, 5.15, and 3,84%, respectively. Avena sativa cv. Millauquén plants were grownth in the pots under greenhouse conditions at different times after atrazine application. Shoots were evenly cut above the soil and dry weight determined as a measure of plant growth. Plants grown in non-sprayed soil were used as controls. Relative dry weight (RDW of shoots was calculated as percentage of control. Atrazine phytotoxicity was expressed in terms of 50 % plant growth reduction (GR50 in the soils under study. Herbicide persistence was expressed in terms of days after treatment (DAT needed for the plant to achieve 80% of RDW. Atrazine GR50 values of 0.30, 0.64, and 0.90 mg.g-1 DSW in soils from San Cayetano, Balcare and A.G. Chaves, were respectively obtained at 42 DAT. Herbicide persistences at the recommended dose (1.16 mg.g-1 were 100, 143, and 221 DAT for A.G. Chaves, Balcarce and San Cayetano soils, respectively. San Cayetano soil had both the lowest OM content and cation exchange capacity (CEC, as well as the highest pH, of all the soil studied here.

    Gadsden, M.

    Pedro Nuñez (the name is also written variously as Nunes, Nonius, Nonnius, and Nunnius) was born at Alcacer do Sol, Portugal, in 1502, and died in 1578. In that period and in that country, it was inevitable that his interests were in cosmography and navigation. His principal claim to fame is as author of the major treatise De Arte Atque Ratione Navigandi, which was published in 1546.

    Full Text Available O objetivo deste trabalho foi avaliar a sensibilidade da goiabeira 'Pedro Sato' ao ozônio (O3, em comparação à cultivar Paluma, descrita como sensível. Oito plantas de cada cultivar foram submetidas separadamente a ar filtrado e a ar filtrado + O3, cinco horas por dia, durante quatro dias. Foram avaliadas fotossíntese (Asat, injúrias foliares visíveis e concentração de antocianinas e taninos. Plantas das duas cultivares também foram expostas, durante três meses, a condições ambientais em local contaminado por O3, tendo-se avaliado fotossíntese, injúrias foliares e crescimento. Plantas fumigadas com O3 apresentaram redução de Asat e da atividade fotoquímica, além de manifestação de injúrias foliares. 'Paluma' apresentou maior redução de Asat, injúrias foliares mais severas e redução de taninos. Quando exposta ao ambiente contaminado, 'Paluma' apresentou trocas gasosas mais altas, mas apresentou redução de Asat 30 dias antes que 'Pedro Sato'. O crescimento não foi afetado em 'Pedro Sato', cujas injúrias foliares tiveram menor incidência, severidade e precocidade do que em 'Paluma'. A menor taxa de crescimento de 'Paluma' indica maior sensibilidade ao O3. Apesar de responder com menor intensidade ao estresse induzido pelo O3, a cultivar Pedro Sato não pode ser considerada tolerante, pois apresenta danos fotoquímicos, injúrias foliares e alterações nos conteúdos de metabólitos secundários quando exposta a esse poluente.

    Full Text Available The Inquisition in 1618 seized all the papers of Pedro de Valencia, renowned humanist, biblical scholar and chronicler of Philip III. The papers of other members of his circle were also confiscated. In this article I examine the two most important texts: Sobre el pergamino y láminas de Granada of Valencia and a Libelo Segundo of Francisco de Gurmendi, interpreter of Oriental languages for Philip III. The article is structured around Gurmendi's response to a memorial published in 1617 by Archbishop Pedro de Castro in defence of one of his translators. Gurmendi, working from his translation of the first two Lead Books, shows how these contain heretical ideas on the Trinity and how the memorialista has mistranslated many passages.

    En 1618 la Inquisición confiscó todos los papeles de Pedro de Valencia, humanista insigne, exegeta bíblico y cronista del reino y de las Indias de Felipe III.

Las imágenes propuestas por el arte callejero impusieron una ruptura con la cultura neo-liberal mediante la fractura del signo: en una primera instancia, inundando los muros en son de denuncia con grafitis, pintadas y esténciles, y en una segunda instancia, asumiendo, mediante enormes murales, una alternativa estética a la capitalización de la ciudad manifiesta en la publicidad y los medios masivos de comunicación.

    Full Text Available Abstract Studies on the political life of the poor in Latin American have rarely focused on money, although there have been works focused on the survival strategies of the poor; political clientelism; and collective mobilizations. In this article, I analyze political life in the poor neighborhoods of Greater Buenos Aires through the lens of money that circulates within the Peronist networks. I conducted ethnography fieldwork between 2006 and 2010. Does money have a legitimate role in politics? Has the monetization of political activities dissolved values, commitments, and loyalties among the poor? Is this corruption, or is this an ethical exchange among people who lack cash but possess moral capital? Here, I analyze how money becomes necessary to strengthen commitments, loyalties, obligations, expectations, and plans for both leaders and activists. Reconstructing this process can provide a foundation for the revision of place of money in political life.

    A new Air Shower Observatory has been constructed in Buenos Aires during 1999, and commissioned and set in operation in 2000. The observatory consists of an array of four water \\v{C}erenkov detectors, enclosing a geometrical area of $\\sim$ 30.000 m$^{2}$, and is optimized for the observation of cosmic rays in the ``knee'' energy region. The array detects $\\sim$ 250 to $\\sim$ 1500 showers/day, depending on the selected triggering condition. In this paper, the design and construction of the array, and the automatic system for data adquisition, daily calibration, and monitoring, are described. Also, the Monte Carlo simulations performed to develop a shower database, as well as the studies performed using the database to estimate the response and the angular and energy resolutions of the array, are presented in detail.

  16. Eugenics in Buenos Aires: discourses, practices, and historiography.

    2016-12-01

    Since the early 1990s, a series of studies underscored the overwhelming presence of positive eugenics in modern Argentina. These works emphasized the marginal role which discourse on eugenics took on violent methods for selection. In recent years, this point of view has shifted, emphasizing the conceptual viscosity of eugenics as well as the presence of negative eugenic discourses. This paper discusses these historiographic trends, and also dwells on the narratives that those perspectives articulated in relation to the question of sterilization and regulation of marriage of those who had tuberculosis in Buenos Aires during the first half of the twentieth century. This example stresses the need to examine discourse as well as practices in understanding and making sense of the past.

    2016-07-01

    Canine monocytic ehrlichiosis (CME) is a worldwide potentially fatal tick-borne rickettsial disease of dogs caused by Ehrlichia canis and transmitted by Rhipicephalus sanguineus sensu lato. CME diagnosis includes indirect (serology) and direct (e.g. blood smears and PCR) methods. PCR is more sensitive and specific than direct microscopic examination and positive PCR results confirm infection, whereas positive serologic test results only confirm exposure. The aim of the present study was to perform a molecular characterization of E. canis from canine samples of the Metropolitan Area of Buenos Aires. We studied 223 blood samples of dogs submitted to our institute for CME diagnoses. The samples were initially screened for Anaplasmataceae family by PCR, resulting in 30 positive dogs (13.4%). Subsequently, positive DNAs were analyzed by nested PCR 16S rRNA specific for E. canis or Anaplasma platys, resulting in 15 (6.7%) and 16 (7.2%) positive dogs, respectively. For molecular characterization, samples positive for E. canis were subjected to amplification of a fragment of the dsb and p28 genes. The nucleotide sequences obtained for the dsb fragment resulted in 100% identity with others E. canis found in dogs from different regions of worldwide. The nucleotide sequences obtained for p28 gene resulted in 100% of identity with each other and closely with E. canis str. Jaboticabal (Brazil). Identity with others sequences of E. canis ranged from 76.9 to 79.7%. The occurrence of canine cases molecularly confirmed in Metropolitan Area of Buenos Aires highlights the need for more studies in order to understand epidemiological factors associated with CME, especially the disease transmission dynamic in South America given the existence of two lineages of R. sanguineus sensu lato with different vectorial capacity for transmission of E. canis.

    Full Text Available The haciendas La Chacarita and Las Conchas, located at the Pago de la Costa in the Buenos Aires countryside, were destined to provide the supplies to the Major College of San Ignacio and to supply the regional market. The exploitation of these lands followed the basic pattern of other Jesuit properties in the territory: it combined stock raising, craft industry and grain production. This paper analyses the level of output of these haciendas and the role of the slave workforce, paying special attention to its structure and components.

    Situadas en el Pago de la Costa, en la campaña bonaerense, las haciendas de La Chacarita y Las Conchas, estaban destinadas a proveer de recursos al Colegio Grande de San Ignacio y a abastecer a un mercado regional. La producción en estas tierras, reproducía el esquema básico de otras propiedades jesuíticas de la Gobernación: combinaba la producción ganadera con la artesanal y el cultivo del cereal. El presente trabajo analiza el grado de producción de estas haciendas y la importancia del empleo de mano de obra esclava, atendiendo especialmente a su estructura y composición.

Par ses caractéristiques la figure mythique du preneur de graisse andin ne peut correspondre à une divinité. La fonction symbolique de la graisse dans les cultures andines préhispanique et actuelle lui donne un premier sens indigène.

    Parsons, Tom; Bruns, Terry R.; Sliter, Ray

    2005-01-01

    The right-lateral San Gregorio and San Andreas faults meet west of the Golden Gate near San Francisco. Coincident seismic reflection and refraction profiling across the San Gregorio and San Andreas faults south of their junction shows the crust between them to have formed shallow extensional basins that are dissected by parallel strike-slip faults. We employ a regional finite element model to investigate the long-term consequences of the fault geometry. Over the course of 2-3 m.y. of slip on the San Andreas-San Gregorio fault system, elongated extensional basins are predicted to form between the two faults. An additional consequence of the fault geometry is that the San Andreas fault is expected to have migrated eastward relative to the San Gregorio fault. We thus propose a model of eastward stepping right-lateral fault formation to explain the observed multiple fault strands and depositional basins. The current manifestation of this process might be the observed transfer of slip from the San Andreas fault east to the Golden Gate fault.

    In Argentina, data on the presence of members of the genus Bartonella is scarce. To increase knowledge about these zoonotic pathogens in this country, the presence and variability of Bartonella spp. was investigated in cats and dogs from Buenos Aires. Bartonella spp. was detected in 17.8% of cats, while all dogs tested negative by PCR and Reverse Line Blot. B. henselae was the most frequent species, being detected in 11.9% (14/101), while B. clarridgeiae was found in only 5.9% (6/101) of the cats. Afterwards, B. henselae isolates and positive blood samples were characterized by Multiple Locus Sequence Typing (MLST) and Multiple Locus Variable Number Tandem Repeats Analysis (MLVA). As result, four different MLST sequence types (ST) and eight MLVA profiles were identified. ST 1 was the most frequent variant found in cats, followed by ST 8. Interestingly, some of the MLVA profiles that were detected in this study have been previously associated with human disease, and represents a potential risk of infection. Veterinarians and physicians should consider the presence of these emerging pathogens in their diagnostic routine.

El objetivo del presente artículo es indagar sobre el mundo educativo porteño estudiando las escuelas de particulares en manos de ingleses, escoceses, irlandeses, norteamericanos y sus descendientes que se instalaron en la ciudad a partir de 1820. Para ello trabajamos con los avisos publicados en la prensa angloparlante de escuelas inglesas, los registros policiales y el Censo Nacional de Escuelas de 1872 así como con opiniones de angloparlantes sobre los niños y la educación de los hijos de extranjeros. A través del estudio de estas fuentes encontramos que las escuelas inglesas formaron parte del heterogéneo mundo educativo porteño y desempeñaron un lugar destacado en la educación de la población tanto de extranjeros como nativos. Estas ofrecían una educación con asignaturas variadas y de mayor complejidad que las escuelas públicas y las de otras particulares llegando a educar a miembros destacados de la sociedad local presentándose como una alternativa al sistema educativo estatal precario o inexistente durante buena parte del siglo XIX.

El análisis de orden cualitativo y desde una dimensión psicológica y social, afronta las trayectorias migratorias de dichas mujeres. Se examinan las motivaciones para emigrar de las jóvenes de donde emerge una fuerte necesidad de emancipación emocional y económica de la familia, emancipación social de la sociedad de origen, encubiertas en gran parte bajo la búsqueda de oportunidades de estudio y profesionales. En el estudio se analizan además, algunos factores de estrés presentes en la experiencia migratoria, la incidencia de la familia y las presiones de orden social que ejerce la sociedad de origen. Se indaga cómo durante el proceso migratorio se van consolidando entre las entrevistadas, la exploración y apropiación de nuevos modos de vida, cómo se van delineando cambios en las relaciones interpersonales, en el ejercicio de los roles sociales y en las relaciones de género.

The array consists of 4 water ˇCerenkov detector stations enclosing a geometrical area of ˜ 30.000 m2 and its design has been optimized for the observation of EAS produced by cosmic rays near the "knee" energy region. Three of the detectors have been constructed using 12000-liter stainless steel tanks, and the fourth has been mounted in a smaller, 400liter plastic container. The detectors are connected by cables to the data acquisition room, where a fully automatic system, which takes advantage of the features of a 4-channel digital oscilloscope, was set for data collection without the need of operator intervention. This automatic experiment control includes monitoring, data logging, and daily calibration of all stations. This paper describes the detectors and their associated electronics, and details are given on the data acquisition system, the triggering and calibration procedures, and the operation of the array. Examples of air shower traces, recorded by the array, are presented.

    Full Text Available Este artículo estudia el proceso de construcción de las parroquias rurales de Buenos Aires a lo largo de casi un siglo. Analiza esta gradual extensión de la red parroquial desde 1730 –la creación de los primeros curatos– hasta la década de 1820 cuando la Iglesia experimentaría cambios decisivos en su configuración como consecuencia de las reformas rivadavianas. El trabajo apunta a dar cuenta de los ritmos diferenciales con que se organizó la red parroquial en distintas zonas de la campaña bonaerense y a identificar los momentos más relevantes de los cambios en la misma. Asimismo examina el clero rural: su peso cuantitativo según áreas y períodos, su composición interna y algunos rasgos de las gestiones parroquiales. En especial considera aquellas acciones que los eclesiásticos exhibían entre sus mayores méritos y servicios, como modo de reconocer lo que –en la época– se esperaba de su actividad pastoral en la cura de almas

    The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

The sequence studied comprises the Guerrero and Río Salado members of the Luján Formation, in which three palaeosols are developed. The geophysical studies suggest an impoverishment of the detrital ferrimagnetic minerals (magnetite and titanomagnetite in the parent material, due to the action of pedogenic processes, accompanied by the generation of two neominerales, one antiferromagnetic and the other ferrimagnetic. The ferrimagnetic mineral consists of particles of ultrafine magnetite (state of superparamagnetic domain, grain size approaching 0.01 µm formed during periods of excess water. The antiferromagnetic minerals (hematite and/or goethite were generated in periods of major water deficiency. The presence of these minerals would be indicating a warm and humid climate with a marked dryperiod. The oldest paleosol was developed on the Guerrero Member which correlates with the Puesto Callejón Viejo palaeosol that has an age between 10,000 and 8,000 years AP, in this profile. The Río Salado Member and the two paleosols developed on it would have developed during the warm period known as, Megathermal, between 9,000 and 7,000 years BP.

    Coma blisters (CBs) are self-limited lesions that occur in regions of pressure during unconscious states classically induced by barbiturates. We report a case of CBs sans coma that were histologically confirmed in a 41-year-old woman who developed multiple tense abdominal bullae with surrounding erythema following a transatlantic flight. Interestingly, the patient was fully conscious and denied medication use or history of medical conditions. A clinical diagnosis of CBs was confirmed by histopathologic findings of eccrine gland necrosis, a hallmark of these bulIous lesions.

Se registraron datos de antecedentes, enfermedad actual, contactos, exposición laboral, examen físico, pruebas de laboratorio y uso previo de antibióticos, y se tomó en cuenta la presencia de criterios de gravedad. Nueve pacientes presentaron diagnóstico de NAC por Legionella, ninguno refirió antecedentes de viajes recientes; cuatro de ellos debieron ser internados en unidades de cuidado intensivo. Siete pacientes tenían antecedentes de tabaquismo, 4 tenían EPOC y un paciente linfoma no-Hodgkin. Nuestra casuística corrobora la baja especificidad de la clínica y estudios complementarios para predecir esta etiología. El aislamiento de Legionella es dificultoso, la seroconversión permite el diagnóstico retrospectivo y requiere plazos prolongados y el antígeno urinario aporta un diagnóstico inmediato. Cuando la legionelosis aparece en casos aislados, como ocurriría en Argentina, si no se piensa en esta etiología no se llegará al diagnóstico.

    Accurate knowledge of the available rheumatology workforce and their working conditions results in better care for patients with rheumatic diseases. The aim of this study was to assess the rheumatology resources and their distribution within district V of the College of Physicians (COLMED5) of Buenos Aires Province, Argentina. All the registered rheumatologists and all the registered public and private institutions within COLMED5 were identified. Aside from these data, phone calls, letters, Internet-derived information, and databases from public and private health insurance providers and the Argentine Society of Rheumatology were included as well. Rheumatologists' per-capita rates were built for both the whole district and every town. A rate of at least 1 rheumatologist per 50,000 people was deemed an optimal resource. Thirty-six rheumatologists were identified; the calculated rate was 1 rheumatologist per 68,403 people; 44% of the health care institutions had a rheumatologist; 33% of them were public institutions. Only 25.5% of COLMED5 total population had optimal rheumatology resources in their town, 70.3% did not reach the optimal resource level but at least had a rheumatologist in their town, and 4.2% had no resources whatsoever; 49% of the total population lacked public health care facilities with inpatient settings and rheumatologists in their town. Although COLMED5 has 72% of the optimal number of rheumatologists, because of their uneven distribution, only 25.5% of the district's total population has the optimal rheumatology resources in their town. Nearly half COLMED5 total population lacks public health care facilities with inpatient settings and rheumatologists in their town, and 4.2% has no available rheumatology resource at all.

    The incidence of fungi like pathogens in hospitals varies by regions. Our goal was not only to record the incidence and etiology of fungaemia, but also the change during the 4 years analysed, to determine the time of detection in automated blood culture and by lysis-centrifugation, and finally to assess the gender, age and underlying disease of the patients with fungaemia. An observational multicentre study of fungaemia was conducted in hospitals in the Mycology Network of Buenos Aires. A total of 190,920 blood cultures were processed: 182,050 automated blood culture and 8,870 lysis-centrifugation. Fungi were recovered in 1,020 episodes. The overall incidence of fungaemia was 1.72/1,000 admissions; 683 episodes were due to Candida (68%), and 325 (32%) to other fungi: 214 Cryptococcus, 105 Histoplasma, 7 Rhodotorula, 5 Trichosporon, 2 Pichia, 2 Acremonium, one Saccharomyces and one Fusarium. The incidence of candidaemia was 1.15/1,000 admissions with a wide variation between centres (0.35 to 2.65). Most Candida isolates (97%) were detected in the first 2 days of incubation. Candida albicans was recovered in 43% of the episodes. In fungaemia other than candidaemia, the predominant fungi were Cryptococcus and Histoplasma capsulatum. The incidence remained stable during the study period. Fungaemia by Candida were predominant. C. albicans was involved in less than a half of the episodes. The recovery of Cryptoccocus and H. capsulatum is strongly associated with HIV patients. Copyright © 2011 Revista Iberoamericana de Micología. Published by Elsevier Espana. All rights reserved.

El presente estudio de tipo observacional de corte transversal, se realizó en caninos de barrios y asentamientos con alto índice de necesidades básicas insatisfechas (NBI en 8 áreas de la ciudad de Buenos Aires. Se estudiaron 219 perros, 184 hembras y 35 machos, que fueron negativos a la prueba de aglutinación con antígeno tamponado (BPAT, que descartó la infección con especies lisas del género Brucella. Sedetectaron anticuerpos anti-B. canis en 16 perros (7.3%, 9 hembras y 7 machos, este último dato es relevante ya que la orina de los machos es considerada uno de los medios de diseminación de la infección. Aunque sólo se pudieron tomar hemocultivos a 175 animales, en 3 (2 hembras y un macho se aislaron B. canis. Sólo 3 de los dueños de los perros positivos accedieron al diagnóstico serológico y dos resultaron positivos. Destacamos que la prueba de inmunodifusión en gel de agar (IGDA ha demostrado ser poco sensible, detectó sólo uno de los 16 casos positivos y ninguno de los tres confirmados por aislamiento. Concluimos que en las áreas estudiadas el hallazgo de perros serológicamente positivos y el aislamiento de B. canis en 3 casos, son indicadores del riesgo en el que se encuentra la salud de la población expuesta.Canine brucellosis, caused by Brucella canis, provokes epidydimitis, testicular atrophy and sterility in male dogs, while in females the major symptom is miscarriage.

    Full Text Available O objetivo desse trabalho foi avaliar o efeito da irradiação gama associada à atmosfera modificada passiva na conservação refrigerada de goiabas ‘Pedro Sato’ minimamente processadas. Foram utilizadas goiabasprovenientes da região de Vista Alegre do Alto/São Paulo/Brasil. Após a colheita, as goiabas foram imediatamente transportadas ao Laboratório de Frutas e Hortaliças, pertencente ao Departamento de Gestão e Tecnologia Agroindustrial, da Faculdade de Ciências Agronômicas – UNESP – Campus de Botucatu/SP, onde foram mantidasa 10ºC e 90-95%UR em câmara frigorífica, por 12 dias. No laboratório, as goiabas foram selecionadas quanto ao tamanho e ausência de defeitos, visando uniformizar o lote e, posteriormente foram cortadas em fatias com 0,5 cm de espessura. Foi utilizado o delineamento inteiramente aleatorizado, com esquema fatorial 5 x 5, com três repetições. O primeiro fator consistiu dos seguintes efeitos: controle 1 (sem embalagem e sem irradiação; controle 2 (embalagem de poliestireno/PS + embalagem de polietileno de baixa densidade/PEBD e sem irradiação; tratamento 1 (PS+PEBD e 0,2kGy; tratamento 2 (PS+PEBD e 0,6kGy e tratamento 3 (PS+PEBD e 1,0kGy. O segundo fator consistiu dos períodos de avaliação, sendo: 0, 3, 6, 9 e 12 dias. As análises realizadas foram: firmeza, sólidos solúveis (SS, acidez titulável (AT, índice de maturação, pH, taxa de respiração. Concluiu-se que a menor dose de irradiação associada a atmosfera modificada passiva promoveu efeito positivo nas característicasfísico-químicas da goiaba ‘Pedro Sato’, proporcionando frutos com maior durabilidade e qualidade, devido a maior manutenção da firmeza de polpa e aos mais elevados valores de pH e sólidos solúveis obtidos. Em relação aos dias de armazenamento, não foi verificado efeito benéfico dos tratamentos no decorrer do armazenamento, principalmente devido à sensibilidade dos frutos submetidos à irradiação gama

    Full Text Available This article analyzes the novel Tengo miedo torero (2001, by Chilean writer Pedro Lemebel. The study aims to demonstrate how that narrative develops a critic discourse about the Chilean history under military dictatorship’s power. The Lemebel’s text can be described as a historiographic metafiction (Hutcheon, 1991. The textual construction, in this novel, is associate with the melodramatic genre, and its writing procedures create a hybrid discursive space where the literary enunciation acknowledges discourses and languages that hasn’t generally been institutionalized by social structures. These constructive aspects contribute for the protagonist character’s subjectivity (Agamben, 2008, an effeminate gay man that is representative character of a social condition characterized by borders and risks. In this novel, then, the performance made by the protagonist shows and promotes some discussions about the (homosexual desire, the individual and collective freedom (Bauman, 1998 and the representations of certain minority groups in Latin American Contemporary Literature.

    Full Text Available The teaching of Astronomy in Brazil is analyzed in the 18 programs of the Pedro II School, relative to the 1841 to 1951 reforms, based on the understanding that the curriculum is the result of a process made up of conflicts and disputes between different traditions and social conceptions. The Astronomy was first identified in the Cosmography subject, although it is absent from the curricula in some periods (1856/58 and 1951 and returns, at other times, included in subjects like Geography and/or Physics (e.g. 1858 and 1931. The non-linearity of the temporal evolution in the curriculum is also observed in the maintenance of subjects such as seasons or eclipses in all the reforms and in the disconnected absence of subject matter like the methods for the star observation or the characterization of the Sun in some of them.

    Directory of Open Access Journals (Sweden)

    Guillermo Carnero

    1992-01-01

    Full Text Available The study deals with the group of Spanish poets commonly called the "novisimos" or "promocion de 1970," using as a base a poem by Pedro Gimferrer published in 1966. It studies the aesthetic break-through achieved by this generation, highlighting the concept of "culturalism" that critics used to define it twenty years ago. It examines the equivocal uses to which this concept can be put, and describes its correct meaning in the light of the aesthetic to which it refers. It then studies the mechanisms implicit in the writing of this non-confessional lyric poetry, centering it on two complementary procedures: the use of a historical persona that serves as an analogue ("personaje historico analogico", and that of another work of art that functions as an objectifying device ("obra de arte ajena objetivadora". It considers these in the light of two perspectives: the overcoming of neo-romantic rhetoric, and the participation of the reader.

    2014-10-01

    Full Text Available In this paper we analyze the TV model presented by Pedro Almodóvar in his filmography. Of the eighteen movies, but three, all contain, one way or another, a reference to TV in a critical sense. Through the analysis of all his films, we observe the way in which TV appears and focus on four models or functions of the TV in his work. The first one has to do with the viewing mode, which we have named “domestic model”. A second function, which we will call “realistic”, is one which means that only what appears on screen exists, but Almodóvar desecrates reality through parody. A third model is a critique of so-called junk televisión. Finally, a fourth function is the presence of other films through the TV screen to establish an intertextual relationship with a narrative purpose.

    Directory of Open Access Journals (Sweden)

    Patricio Lizama

    2012-11-01

    Full Text Available En este trabajo estudiamos textos de Pedro Prado desde una perspectiva mística, la cual es entendida por el autor con un fundamento religioso y otro ético-social. Por ello, sus personajes se elevan hacia niveles últimos de realidad, pero no se apartan de la "tierra de hombres" y se convierten en videntes que anhelan la belleza y la justicia. En "La barca", los personajes realizan un viaje horizontal y otro vertical para enfrentar el misterio; enAlsino, el viaje vertical es también para acercarse a la divinidad y el horizontal para enjuiciar el mundo rural chileno. La mediación entre el arriba y el abajo se representa con una embarcación que navega y vuela y con un hombre que camina y vuela, ambas figuras entendidas como alegorías del artista.This paper provides an analysis of the writings by Pedro Prado from a mystical perspective, an approach that the author himself understands as having religious as well as socio-ethical foundations. This is why Prado's characters rise towards ultimate levels of reality, but they never lose touch with the "land of men" to the point of turning into seers who yearn for beauty andjustice. In "La barca", the characters undertake a vertical ass well ass a horizontal journey in order to face the mystery. In Alsino, on the other hand, the vertical journey also serves to approach the divine, whereas the horizontal one is used to judge the Chilean rural world. The mediation between that which is above and what is below is represented by a ship that sails and flies, as well as by a man who walks and flies, both of which are to be seen as allegories of the artist.
