    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.

    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.

  6. Vegetation history along the eastern, desert escarpment of the Sierra San Pedro Mártir, Baja California, Mexico

    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.

    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 United States and Mexico share waters in a number of hydrological basins and aquifers that cross the international boundary. Both countries recognize that, in a region of scarce water resources and expanding populations, a greater scientific understanding of these aquifer systems would be beneficial. In light of this, the Mexican and U.S. Principal Engineers of the International Boundary and Water Commission (IBWC) signed the “Joint Report of the Principal Engineers Regarding the Joint Cooperative Process United States-Mexico for the Transboundary Aquifer Assessment Program" on August 19, 2009 (IBWC-CILA, 2009). This IBWC “Joint Report” serves as the framework for U.S.-Mexico coordination and dialogue to implement transboundary aquifer studies. The document clarifies several details about the program such as background, roles, responsibilities, funding, relevance of the international water treaties, and the use of information collected or compiled as part of the program. In the document, it was agreed by the parties involved, which included the IBWC, the Mexican National Water Commission (CONAGUA), the U.S. Geological Survey (USGS), and the Universities of Arizona and Sonora, to study two priority binational aquifers, one in the San Pedro River basin and the other in the Santa Cruz River basin. This report focuses on the Binational San Pedro Basin (BSPB). Reasons for the focus on and interest in this aquifer include the fact that it is shared by the two countries, that the San Pedro River has an elevated ecological value because of the riparian ecosystem that it sustains, and that water resources are needed to sustain the river, existing communities, and continued development. This study describes the aquifer’s characteristics in its binational context; however, most of the scientific work has been undertaken for many years by each country without full knowledge of the conditions on the other side of the border. The general objective of this study is to

    In the middle San Pedro Watershed in southeastern Arizona, groundwater is the primary source of water supply for municipal, domestic, industrial, and agricultural use. The watershed comprises two smaller subareas, the Benson subarea and the Narrows-Redington subarea. Early 21st century projections for heavy population growth in the watershed have not yet become a reality, but increased groundwater withdrawals could have undesired consequences—such as decreased base flow to the San Pedro River, and groundwater-level declines—that would lead to the need to deepen existing wells. This report describes the hydrology, hydrochemistry, water quality, and development of a groundwater budget for the middle San Pedro Watershed, focusing primarily on the elements of groundwater movement that could be most useful for the development of a groundwater model

    the upper basin fill may be more permeable than the lower basin fill, but it is generally unsaturated in the study area. The lower basin fill stratigraphic unit was delineated into three HGUs on the basis of lithologic descriptions in driller?s logs and one-dimensional (1D) electrical models of airborne transient electromagnetic (TEM) surveys. The interbedded lower basin fill (ILBF) HGU represents an upper sequence having resistivity values between 5 and 40 ohm-m identified as interbedded sand, gravel, and clay in driller?s logs. Below this upper sequence, fine-grained lower basin fill (FLBF) HGU represents a thick silt and clay sequence having resistivity values between 5 and 20 ohm-m. Within the coarse-grained lower basin fill (CLBF) HGU, which underlies the silt and clay of the FLBF, the resistivity values on logs and 1D models increase to several hundred ohm-m and are highly variable within sand and gravel layers. These sequences match distinct resistivity and lithologic layers identified by geophysical logs in the adjacent Sierra Vista subwatershed, suggesting that these sequences are laterally continuous within both the Benson and Sierra Vista subwatersheds in the Upper San Pedro Basin. A subsurface density model based on gravity data was constructed to identify the top of bedrock and structures that may affect regional groundwater flow. The subsurface density model contains six layers having uniform density values, which are assigned on the basis of geophysical logs. The density values for the layers range between 1.65 g/cm3 for unsaturated sediments near the land surface and 2.67 g/cm3 for bedrock. Major features include three subbasins within the study area, the Huachuca City subbasin, the Tombstone subbasin, and the Benson subbasin, which have no expression in surface topography or lithology. Bedrock altitudes from the subsurface density model defined top altitudes of the bedrock HGU. The HFM includes the following HGUs in ascending stratigr

    Seafloor samples, videography, still photography, and real-time descriptions of geologic and biologic constituents at or near the seafloor of the San Pedro Shelf, southern California, advance the study of natural and man-made processes on this coastal area off the metropolitan Los Angeles area. Multibeam echo-sounder data collected by the U.S. Geological Survey in 1998 and 1999 guided sampling and camera work in 2004 resulting in a new seafloor character map that shows possible benthic habitats in much higher resolution (4- and 16-m pixels) than previously available. The seafloor is characterized by primarily muddy sand and sand with outcrops of Miocene and Pliocene bedrock along the Palos Verdes Fault Zone. Observed benthic populations indicate low abiotic complexity, low biotic complexity, and low biotic coverage. The data are provided for use in geographic information systems (GIS).

    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.

    Science.gov (United States)

    Carod-Artal, F J; Vázquez-Cabrera, C B

    The San Pedro cactus contains the alkaloid mescaline and other derivates of phenethylamine with hallucinogenic properties. This cactus was used throughout history by a number of different pre-Columbine cultures and civilisations that settled in northern Peru. In this article we review the ethno-archaeological and ethno-historical evidence of the ritual use of the San Pedro cactus in the pre-Columbine cultures, and these findings are compared with the information provided by current ethnographical studies. The longer a cactus has been stored, the stronger and the higher its content in mescaline-derived alkaloids will be. Archaeological evidence has been found of the use of San Pedro for magical-religious purposes in the following pre-Columbine cultures: Cupisnique (1500 BC), Chavin (1000 BC), Moche (100-750 AD) and Lambayeque (750-1350 AD). Today's master shamans use San Pedro on altars ('mesas') erected for healing rites in order to treat enchantment and bad luck. The mesa follows a sophisticated ritual: 'levantar' (raise) or sniff tobacco with alcohol, ingest San Pedro, pinpoint the diseases, cleanse the evil and 'florecer' (flourish) the sick person. The mesa rite is performed in the early hours of Tuesdays and Fridays, which are sacred days in the Andean religions. San Pedro is sometimes replaced by an infusion of plants and seeds that contain hallucinogenic components, such as ayahuasca and the 'mishas' (Brugmansia sp.). The ancient tradition of using the San Pedro cactus for healing and hallucinogenic purposes has remained part of the culture in Andean shamanism up to the present day.

    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.

    Groundwater managers in the semiarid Southwest U.S. must balance the demands of growing populations against the needs of rare riparian ecosystems. The Upper San Pedro River Basin in Southeastern Arizona provides water for the rapidly growing area of Fort Huachuca, Sierra Vista, and surrounding communities. This basin also supports the riparian area by providing baseflow to the San Pedro River and shallow groundwater to phreatic riparian vegetation. Before water managers can properly plan for sustenance of the riparian area, they require answers about the inputs of baseflow into the river. What is the temporal and spatial variability of recharge and discharge? What are the relative inputs of different sources (i.e. recharge of monsoon runoff and inflow of basin groundwater) into the riparian aquifer? We have used a suite of geochemical tracers to address these questions. Most precipitation in this region falls during the summer monsoons and winter frontal storms. Because these events have different source areas, their respective stable isotopic signatures differ. We use these isotopic compositions as end members in mixing equations in order to determine the dominant season for recharge. Groundwater in the basin has a narrow range of stable isotope compositions, varying from 62 to 72% winter precipitation. The basin isotopic composition is very similar to water in the mountain front and block, indicating that recharge from these areas is the dominant source for basin groundwater. Basin groundwater residence times, determined using the radioactive isotope carbon-14, are on the order of 10,000 years or more, indicating a low recharge rate. In contrast, riparian groundwater has a wide variation of isotopic values, indicating that this water is a mixture of basin groundwater and monsoon runoff, varying from 20 to 90% basin groundwater. The dominance of basin groundwater or monsoon runoff in different areas of the river correlates well with independent classification of

    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.

    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.

    The coastal infrastructure of the southern greater Los Angeles metropolitan area would be profoundly affected by a large tsunami. Submarine slope failures and active faults, either of which could have generated a tsunami, are known on the shelf and slope near Long Beach. Large slope failures are present on the San Pedro Escarpment and on the basin slope adjacent to the San Pedro shelf. The southeastern part of the escarpment has had a long history of slope failure. The most recent failure, the Palos Verdes slide, is over 4.5 km long, has been dated as 7500 years old, and involved over 0.34 km 3 of material, which now litters the adjacent basin floor. Other, smaller, deposits from nearby failures are also present, as are buried wedges of debris that indicate slope failures have occurred locally throughout the Holocene and much of the late Pleistocene. Slope failures have occurred in response to continual Quaternary uplift of the Palos Verdes anticlinorium. The Palos Verdes slide could potentially have generated a failure-related tsunami with an amplitude in the range of 8-12 m because it apparently failed catastrophically, started in shallow water, evolved on low-drag bedding planes, had a long slide path, and involved high-strength lithified material. ?? 2003 Elsevier B.V.

    Place names often provide examples of the importance that a heritage stone has had with the foundation of cities and throughout its subsequent history. The heritage of a town is related to its geological environment, which provides its construction materials. The historic quarry of San Pedro leucogranite in northwest Spain is considered here and its petrological characteristics, utilization throughout history and its heritage value are evaluated. The Romans used this stone, however there was an initial boom in the use of San Pedro leucogranite for Galician Romanesque sculptures during the Middle Ages. Notable among other monuments such as the twelfth century Romanesque churches of Santa María del Campo and Santiago and it has also been used to build the pedestal of Herculeś Tower, this is a majestic lighthouse in A Coruña city, it was declared World Heritage by UNESCO in 2 009. San Pedro leucogranite is part of the pavement of the main tourist streets of A Coruña city (Calle Real and Cantones, to name some of the most popular). Betanzos is a historical village about 25 km from A Coruña, its historical center was declared historic-artistic site in 1970. The Betanzos historical center also provides major utilization of this stone in sculptures and ashlars of San Francisco and Santa María de Azogue churches, among others. Color, rarity, appearance, quality and durability are the primary characteristics that have led to San Pedro leucogranite being used for sculpting and building. These characteristics and historical quarrying should be assessed with respect to its heritage significance and strategic location near the city of A Coruña. The preservation and enhancement of its historic quarries that are essential for conservation work and restoration of heritage assets built with the San Pedro leucogranite in this region.

    Full Text Available Developed in the United States, the Cure Violence model is a programme of epidemic control that reduces violence through changes to norms and behaviour. This article primarily examines the issue of violence in Honduras and, in particular, in San Pedro Sula which was for years the city with the highest homicide rates in the world. To tackle this situation, in 2013 an adapted version of the programme began to be implemented in certain areas of the city. After describing the adaptation of the model to the context of the Honduran city, its results are analysed in two periods of 2014 and 2015 (compared to 2013 and 2014, respectively: a significant reduction in shootings and a minor fall in the homicide figures stand out.

    Transboundary aquifers along the U.S.-Mexico border are subject to unique demands and constraints, and are a focus of priority assessment under the auspices of the Transboundary Aquifer Assessment Program. The Upper Santa Cruz and Upper San Pedro basins in southern Arizona are experiencing rapid population growth and development, and the associated water and environmental resource demands are stressors to water resource sustainability. A groundwater vulnerability assessment was performed to evaluate groundwater resources within these two basins using DRASTIC (Depth to water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone media, and hydraulic Conductivity of the aquifer). DRASTIC analysis is a standardized method developed by the Environmental Protection Agency for evaluating groundwater pollution potential. DRASTIC was used to characterize the potential for contamination of groundwater by land surface sources. Data layers for the DRASTIC analysis were compiled and analyzed separately based on rating methods from DRASTIC. These methods rate each layer on a scale of one to ten, one being the least vulnerable to contamination and ten being the most vulnerable. Weights for each layer were also provided by DRASTIC based on each layer's contribution to the overall vulnerability of the aquifer. These layers were then analyzed using the equation: DRDW+RRRW+ARAw+SRSW+TRTW+IRIW+CRCW = Pollution Potential, where R = rating, and W = weight. This assessment was coupled with current knowledge of groundwater contamination and current land use practices to identify zones of potential concern. This information can be used to better direct city planning, zoning programs, and groundwater monitoring and remediation efforts throughout the Upper Santa Cruz and Upper San Pedro basins.

    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

    Full Text Available Earth, wood and others traditional materials are still used in house constructions in many regions of the world, especially in the Andes. 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.

  8. Evaluation of NDVI to assess avian abundance and richness along the upper San Pedro River

    McFarland, T.M.; van Riper, Charles; Johnson, G.E.

    2012-01-01

    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.

    The objective of this study was to determine the seasonal and downstream water quality variations of the San Pedro River in Chihuahua, Mexico. Water samples were collected monthly from October 2005 to August 2006 in triplicate, totaling 165 water samples. The five sampling locations were: below the Francisco I. Madero dam (LP); between Rosales and Delicias (RD); Meoqui (M); El Torreon (ET), and Julimes (LJ). The levels of As, Be, Ca, Cd, Co, Cu, Cr, Fe, Li, Mg, Mn, Mo, Ni, Pb, Sb, Se, Sr, Ti, Ta, V and Zn were measured using an Inductively Coupled Plasma- Optical Emission Spectrometry (ICP-OES) Perkin Elmer 2100. 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.

    Full Text Available The objective of this study was to determine the seasonal and downstream water quality variations of the San Pedro River in Chihuahua, Mexico. Water samples were collected monthly from October 2005 to August 2006 in triplicate, totaling 165 water samples. The five sampling locations were: below the Francisco I. Madero dam (LP; between Rosales and Delicias (RD; Meoqui (M; El Torreon (ET, and Julimes (LJ. The levels of As, Be, Ca, Cd, Co, Cu, Cr, Fe, Li, Mg, Mn, Mo, Ni, Pb, Sb, Se, Sr, Ti, Ta, V and Zn were measured using an Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES Perkin Elmer 2100. 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.

  16. Biogeochemical Insights into B-Vitamins in the Coastal Marine Sediments of San Pedro Basin, CA

    Coastal marine sediments support a high abundance of mircoorganisms which play key roles in the cycling of nutrients, trace metals, and carbon, yet little is known about many of the cofactors essential for their growth, such as the B-vitamins. The suite of B-vitamins (B1, B2, B6, B7, B12) are essential across all domains of life for both primary and secondary metabolism. Therefore, studying sediment concentrations of B-vitamins can provide a biochemical link between microbial processes and sediment geochemistry. Here we present B-vitamin pore water concentrations from suboxic sediment cores collected in September 2014 from San Pedro Basin, a silled, low oxygen, ~900 m deep coastal basin in the California Borderlands. We compare the B-vitamin concentrations (measured via LCMS) to a set of geochemical profiles including dissolved Fe (65-160 μM), dissolved Mn (30-300 nM), TCO2, solid phase organic carbon, and δ13C. Our results show high concentrations (0.8-3nM) of biotin (B7), commonly used for CO2 fixation as a cofactor in carboxylase enzymes. Thiamin (B1) concentrations were elevated (20-700nM), consistent with previous pore water measurements showing sediments could be a source of B1 to the ocean. Cobalamin (B12), a cofactor required for methyl transfers in methanogens, was also detected in pore waters (~4-40pM). The flavins (riboflavin [B2] and flavin mononucleotide[FMN]), molecules utilized in external electron transfer, showed a distinct increase with depth (10-90nM). Interestingly, the flavin profiles showed an inverse trend to dissolved Fe (Fe decreases with depth) providing a potential link to culture experiments which have shown extracellular flavin release to be a common trait in some metal reducers. As some of the first B-vitamin measurements made in marine sediments, these results illustrate the complex interaction between the microbial community and surrounding geochemical environment and provide exciting avenues for future research.

  20. Estimating Earthquake Hazards in the San Pedro Shelf Region, Southern California

    2003-12-01

    The San Pedro Shelf (SPS) region of the inner California Borderland offshore southern California poses a significant seismic hazard to the contiguous Los Angeles Area, as a consequence of late Cenozoic compressional reactivation of mid-Cenozoic extensional faults. The extent of the hazard, however, is poorly understood because of the complexity of fault geometries and uncertainties in earthquake locations. The major faults in the region include the Palos Verdes, THUMS Huntington Beach and the Newport-Inglewood fault zones. We report here the analysis and interpretation of wide-angle seismic-reflection and refraction data recorded as part of the Los Angeles Region Seismic Experiment line 1 (LARSE 1), multichannel seismic (MCS) reflection data obtained by the USGS (1998-2000) and industry borehole stratigraphy. The onshore-offshore velocity model, which is based on forward modeling of the refracted P-wave arrival times, is used to depth migrate the LARSE 1 section. Borehole stratigraphy allows correlation of the onshore and offshore velocity models because state regulations prevent collection of deep-penetration acoustic data nearshore (within 3 mi.). Our refraction study is an extension of ten Brink et al., 2000 tomographic inversion of LARSE I data. They found high velocities (> 6 km/sec) at about ~3.5 km depth from the Catalina Fault (CF) to the SPS. We find these velocities, shallower (around 2 km depth) beneath the Catalina Ridge (CR) and SPS, but at a depth 2.5-3.0 km elsewhere in the study region. This change in velocity structure can provide additional constraints for the tectonic processes of this region. The structural horizons observed in the LARSE 1 reflection data are tied to adjacent MCS lines. We find localized folding and faulting at depth (~2 km) southwest of the CR and on the SPS slope. Quasi-laminar beds, possible of pelagic origin follow the contours of earlier folded (wavelength ~1 km) and faulted Cenozoic sedimentary and volcanic rocks. Depth to

    We investigated the effects of elevated carbon dioxide [CO2] on biogeochemistry of marsh sediment including speciation of selected heavy metals in Salinas de San Pedro mudflat in California. The Salinas de San Pedro mudflat has higher carbon (C) content than the vast majority of fully-vegetated salt marshes even with the higher tidal action in the mudflat. Sources for CO2 were identified as atmospheric CO2 as well as due to local fault degassing process. We measured carbon dioxide [CO2], methane [CH4], total organic carbon, dissolved oxygen, salinity, and heavy metal concentration in various salt marsh locations. Overall, our results showed that CO2 concentration ranging from 418.7 to 436.9 [ppm], which are slightly different in various chambers but are in good agreement with some heavy metal concentrations values in mudflat at or around the same location. The selected metal concentration values (ppm) ranging from 0.003 - 0.011(As); 0.001-0.005 (Cd); 0.04-0.02 (Cr); 0.13-0.38 (Cu); 0.11-0.38 (Pb); 0.0009-0.020 (Se); and 0.188-0.321 (Zn). The low dissolved O2 [ppm] in the pore water sediment indicates suboxic environment. Additionally, CO2 [ppm] and loss on ignition (LOI) [%] correlated inversely; the higher CO2 content, the lower was the LOI; that is to say the excess CO2 may caused higher rates of decomposition and therefore it leads to lower soil organic matter (LOI) [%] on the mudflat surface. It appears that the elevated CO2 makes changes in salt marsh pore water chemistry for instance the free ionic metal (Cu2+, Pb2+, etc.) speciation is one of the most reactive form because simply assimilated by the non-decayed or alive organisms in sediment of salt marsh and/or in water. This means that CO2 not only is a sign of improvement in plant productivity, but also activates microbial decomposition through increases in dissolved organic carbon availability. CO2 also increases acidification processes such as anaerobic degradation of microorganism and oxidation of

    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.

    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.

    Oceanic time-series have provided insight into biological, physical, and chemical processes and how these processes change over time. However, time-series data collected near coastal zones have not been used as broadly because of regional features that may prevent extrapolation of local results. Though these sites are inherently more affected by local processes, broadening the application of coastal data is crucial for improved modeling of processes such as total carbon drawdown and the development of oxygen minimum zones. Slocum gliders were deployed off the coast of Los Angeles from February to July of 2013 and 2014 providing high temporal and spatial resolution data of the San Pedro Channel (SPC), which includes the San Pedro Ocean Time Series (SPOT). The data were collapsed onto a standardized grid and primary and secondary characteristics of glider profiles were analyzed by principal component analysis to determine the processes impacting SPC and SPOT. The data fell into four categories: active upwelling, offshore intrusion, subsurface bloom, and surface bloom. Waters across the SPC were most similar to offshore water masses, even during the upwelling season when near-shore blooms are commonly observed. The SPOT site was found to be representative of the SPC 86% of the time, suggesting that the findings from SPOT are applicable for the entire SPC. Subsurface blooms were common in both years with co-located chlorophyll and particle maxima, and results suggested that these subsurface blooms contribute significantly to the local primary production. Satellite estimation of integrated chlorophyll was poor, possibly due to the prevalence of subsurface blooms and shallow optical depths during surface blooms. These results indicate that high resolution in-situ glider deployments can be used to determine the spatial domain of coastal time-series data, allowing for broader application of these datasets and greater integration into modeling efforts.

This cosmovision is not a static model but a cultural product of a historical process that embraces a mixture of continuities and ruptures, popular believes and the imposition of a official religion and a civilization of customs by the Church

    [gl] Este artigo recolle a análise arqueohistórica do proceso de conformación dunha paisaxe cultural a escala local, como é a parroquia de S. Pedro de Cereixa (Pobra de Brollón, Lugo. Partindo da Arqueoloxía da Paisaxe reconstruímo-las diferentes estratexias de construcción do espacio social empregadas polas sucesivas formacións socioculturais que ocuparon a zona dende a Prehistoria Recente deica a actualidade. Na segunda parte achegámonos ó patrón de racionalidade manexado pola comunidade campesina que construíu e dotou de sentido á paisaxe rural tradicional. Para acadar este obxectivo, desenvolvemos unha aproximación interdisciplinar coa angueira de maximizar tanto as aportacións de diferentes tendencias historiográficas (Historia Rural, Antropoloxía Histórica, Microhistoria como a potencialidade da utilización conxunta de diversas ferramentas metodolóxicas, nomeadamente o baldeirado de fontes documentais secundarias, a enquisa etnográfica, a análise iconográfica e a Historia Oral.

    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.

    Full Text Available 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 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.

    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

    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.

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.

    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.

    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 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.

    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 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.

Rowlandius arduus sp. n. se caracteriza por el dedo móvil del quelícero con un diminuto diente subdistal, una débil eminencia dorsoposterior en el segmento abdominal XII del macho y espermatecas constituidas por dos pares de lóbulos largos y sinuosos, tenuemente quitinizados, sin bulbo terminal notable. Su asignación al género Rowlandius es tentativa, pues posee varios caracteres que no concuerdan plenamente con el mismo, sin embargo la carencia de caracteres sinapomórficos limita su asignación a otro género. Este es el primer registro del género para Venezuela y la tercera especie suramericana conocida.A new species of the genus Rowlandius Reddell & Cokendolpher, 1995 is described from Sierra San Luis, Falcón State, northwestern Venezuela. Rowlandius arduus sp. n. may be characterized by having movable finger of chelicerae with a diminute sub-distal tooth, male with a poorly developed dorsal eminence on abdominal segment XII, and female with two pairs of weakly sclerotized, sinuous spermathecal lobes, without conspicuous terminal lobe. It is assigned to Rowlandius tentatively, because some characters are not congruent with this genus, nevertheless the absence of synapomorphic characters limits its inclusion in other one. This is the first record of the genus from Venezuela, and the third South American species described.

  15. Recent deformation on the San Diego Trough and San Pedro Basin fault systems, offshore Southern California: Assessing evidence for fault system connectivity.

    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

Se analizó una cronología de ancho de anillos para un bosque de A. acuminata en San Pedro de Saño y se relacionó el crecimiento de los árboles con los registros instrumentales de temperatura media, máxima y mínima, precipitación y horas sol de las estaciones meteorológicas de Huayao (12° 02´ 18.1¨ S - 75° 19´22.2¨ O y Santa Ana (12° 00´ 15¨ S - 75° 13´ 15¨ O. 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.

    Estimation of riparian forest structural attributes, such as the Leaf Area Index (LAI), is an important step in identifying the amount of water use in riparian forest areas. In this research, small footprint lidar data were used to estimate biophysical properties of young, mature, and old cottonwood trees in the Upper San Pedro River Basin, Arizona, USA. Canopy height and maximum and mean laser heights were derived for the cottonwood trees from lidar data. Linear regression models were used to develop equations relating lidar height metrics with corresponding field measured LAI for each age class of cottonwoods. Four metrics (tree height, height of median energy, ground return ratio, and canopy return ratio) were derived by synthetically constructing a large footprint lidar waveform from small-footprint lidar data which were compared to ground-based high- resolution Intelligent Laser Ranging and Imaging System (ILRIS) scanner images. These four metrics were incorporated into a stepwise regression procedure to predict field-derived LAI for different age classes of cottonwoods. The Penman-Monteith model was then used to estimate transpiration of the cottonwoods using the lidar-derived canopy metrics. These transpiration estimates compared very well to ground-based sap flux transpiration estimates indicating lidar-derived LAI can be used to improve riparian cottonwood water-use estimates. Future research will attempt to fuse high spatial resolution multispectral or hyperspectral data and lidar data to improve classification results for species identification in the Upper San Pedro River Basin.

    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

    Full Text Available An experimental study was carried out during seven weeks to preliminarily evaluate the effect of the dietary inclusion of powder from the tuber Lasianthaeapodocephala, commonly known as the San Pedro daisy or pionilla, as a feed additive on the production parameters, food consumption, and nutritional condition of the white shrimp, Litopenaeus vannamei, intensively farmed under laboratory conditions. Hypothetically, the additive should improve these parameters as it does when used for humans. The powder was included at different levels (0 [Control], 0.2 [T1] and 1 g kg-1 [T2] in a commercial shrimp feed. 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.

    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.

Los ejemplares masculinos presentaron valores medios mayores que los femeninos en la mayoría de las variables analizadas. La influencia de los restantes factores se manifestó en un tercio de las medidas craneométricas. Entre las clases adulto y maduro se comprobó un incremento significativo de los promedios. El efecto de la deformación artificial se destaca principalmente por alteraciones en el crecimiento de la bóveda y, en menor medida, en la cara y en la base del cráneo. Un hallazgo de importancia lo constituye la existencia de variación cronológica indicando cambios en la estructura de la población en el período estudiado.

    2017-07-01

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

    Full Text Available The F-(Pb, Zn, Ba district of Sierra de Baza are a (Southeastern Spain is mainly constituted by fluorite-(galene stratiform and stratabound mineralizations which are included in Carbonate levels of Ladinian-Carnian age. These levels also contain vein mineralizations but only in certain zones as de Calar de San José and the Calar de Santa Bárbara. This paper deals with the main structural and mineralogical characteristics of the vein mineralizations and their relations with the geological context evolution. Special attention is given to the tectonic and the spatial association with the stratiform and stratabound, mineralizations of sedimentary/diagenetic character. Two types of vein mineralizations may be distinguished : one type is represented by small "in situ" remobilizations, from the stratiform and stratabound mineralizat ioos, which have been formed during the final stages of alpine deformations; the other one has been formed before Alpina Orogeny and probably in direct relation with an intratriassic tectonic phase.

  11. Institutions and Societal Impacts of Climate in the Lower Colorado and San Pedro Basins of the U.S.-Mexico Border Region

    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 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.

    2007-05-01

    Médecins Sans Frontières has been involved in emergency mental health or psychosocial programmes since 1990. In this article the intervention model developed for emergency settings is shared. Psychosocial programmes distinguish two elements. The 'psycho'-component facilitates the reconnection of the affected individual to his environment. The 'socio'-element aims to create an environment that facilitates the individual to re-integrate. The nature of mental health and psychosocial programmes requires a multidisciplinary approach. Emotional support can also be provided by regular medical staff and does not always require a specialist. The years ahead of us are important for the development of psychosocial interventions. Fundamental issues such as programme evaluation need systematic research.

Lithological descriptions, their stratigraphic relationships and complimentary lithochemical characterizations carried out in the San Miguel region (East Uruguay are presented. Three volcanic/sub-volcanic units have been recognized. The felsic volcanic association is composed by rhyolitic - dacitic flows, mainly with porphyritic textures and sub-alkalinenature and related pyroclastic rocks. The felsic sub-volcanic association is characterized by granophyres of about 25 km2 of exposed area, cross- cut by mafic and felsic dykes. Finally, a mafic association has been identified characterized by dykes and a small intrusion of gabbroic composition.All these units are Mesozoic in age (130 - 127 Ma and according to their chemical nature they correspond tosub-alkaline to weak peralkaline magmas.

  20. Improving the Flash Flood Frequency Analysis using dendrogeomorphological evidences in the Arenal River crossing Arenas de San Pedro Village (Spanish Central System)

    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

    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 (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.

    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.

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

    Geologic mapping in the northern Sierra Los Ajos reveals new stratigraphic and structural data relevant to deciphering the Mesozoic-Cenozoic tectonic evolution of the range. The northern Sierra Los Ajos is cored by Proterozoic, Cambrian, Devonian, Mississippian, and Pennsylvanian strata, equivalent respectively to the Pinal Schist, Bolsa Quartzite and Abrigo Limestone, Martin Formation, Escabrosa Limestone, and Horquilla Limestone. The Proterozoic-Paleozoic sequence is mantled by Upper Cretaceous rocks partly equivalent to the Fort Crittenden and Salero Formations in Arizona, and the Cabullona Group in Sonora, Mexico. Absence of the Upper Jurassic-Lower Cretaceous Bisbee Group below the Upper Cretaceous rocks and above the Proterozoic-Paleozoic rocks indicates that the Sierra Los Ajos was part of the Cananea high, a topographic highland during the Late Jurassic and Early Cretaceous. Deposition of Upper Cretaceous rocks directly on Paleozoic and Proterozoic rocks indicates that the Sierra Los Ajos area had subsided as part of the Laramide Cabullona basin during Late Cretaceous time. Basal beds of the Upper Cretaceous sequence are clast-supported conglomerate composed locally of basement (Paleozoic) clasts. The conglomerate represents erosion of Paleozoic basement in the Sierra Los Ajos area coincident with development of the Cabullona basin. The present-day Sierra Los Ajos reaches elevations of greater than 2600 m, and was uplifted during Tertiary basin-and-range extension. Upper Cretaceous rocks are exposed at higher elevations in the northern Sierra Los Ajos and represent an uplifted part of the inverted Cabullona basin. Tertiary uplift of the Sierra Los Ajos was largely accommodated by vertical movement along the north-to-northwest-striking Sierra Los Ajos fault zone flanking the west side of the range. This fault zone structurally controls the configuration of the headwaters of the San Pedro River basin, an important bi-national water resource in the US

    Geologic mapping in the northern Sierra Los Ajos reveals new stratigraphic and structural data relevant to deciphering the Mesozoic–Cenozoic tectonic evolution of the range. The northern Sierra Los Ajos is cored by Proterozoic, Cambrian, Devonian, Mississippian, and Pennsylvanian strata, equivalent respectively to the Pinal Schist, Bolsa Quartzite and Abrigo Limestone, Martin Formation, Escabrosa Limestone, and Horquilla Limestone. The Proterozoic–Paleozoic sequence is mantled by Upper Cretaceous rocks partly equivalent to the Fort Crittenden and Salero Formations in Arizona, and the Cabullona Group in Sonora, Mexico.Absence of the Upper Jurassic–Lower Cretaceous Bisbee Group below the Upper Cretaceous rocks and above the Proterozoic–Paleozoic rocks indicates that the Sierra Los Ajos was part of the Cananea high, a topographic highland during the Late Jurassic and Early Cretaceous. Deposition of Upper Cretaceous rocks directly on Paleozoic and Proterozoic rocks indicates that the Sierra Los Ajos area had subsided as part of the Laramide Cabullona basin during Late Cretaceous time. Basal beds of the Upper Cretaceous sequence are clast-supported conglomerate composed locally of basement (Paleozoic) clasts. The conglomerate represents erosion of Paleozoic basement in the Sierra Los Ajos area coincident with development of the Cabullona basin.The present-day Sierra Los Ajos reaches elevations of greater than 2600 m, and was uplifted during Tertiary basin-and-range extension. Upper Cretaceous rocks are exposed at higher elevations in the northern Sierra Los Ajos and represent an uplifted part of the inverted Cabullona basin. Tertiary uplift of the Sierra Los Ajos was largely accommodated by vertical movement along the north-to-northwest-striking Sierra Los Ajos fault zone flanking the west side of the range.

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

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.

    Full Text Available Natural Protected Areas (NPAs includes important species richness, and it is assumed that these are the best areas for biodiversity conservation. There are certain doubts, however, about the effectiveness of the NPAs in developing countries, where economic resources for conservation are scarce and NPAs are not monitored and managed efficiently. In the present study we assessed the species richness, diversity, abundance, and functional guilds of amphibians and reptiles inside and outside of the NPA Reserva Estatal de la Biósfera Sierra San Juan (REBSSJ, Nayarit, Mexico. Our results showed that species numbers of amphibian and reptiles were higher outside than inside the reserve, as well the individual number distributed among species, except for lizard species. Analyses of functional guilds showed that both richness and functional dispersion were greater in amphibians and reptiles outside the reserve. Likewise, outside the reserve we recorded a higher species number with some category of risk at the national level (NOM-059, international level (IUCN, and also by using the Environmental Vulnerability Score (EVS algorithm. The results suggest that areas outside of the reserve are crucial to the maintenance of regional biodiversity, due to high complementarity with species composition inside of the reserves. These data can be used to implement conservation measures that include a new demarcation of the reserve and the consideration of surrounding areas to include a great number of species.

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

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.

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.

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

The proposal considered two kinds of interventions. In one hand, the traditional restoration of the few pieces preserved in their original state. In another hand, rebuilding it with a new design that should optimize it for public use and also create an homogeneous coordination of the architectural "fragments" which before had no link between them.

    El conjunto que forman la iglesia de San Martín y el Palacio de los Falces de Medina del Campo se encontraba en un estado lamentable cuando se decidió actuar en él: arruinado y saqueado. En cuanto a la iglesia de San Juan Bautista de Guadalix de la Sierra, sólo la torre y la cabecera tenían interés arquitectónico, ya que la nave era una pobre construcción reedificada en 1944. En ambos casos, el proyecto propuso una doble forma de intervención. Por un lado, la restauración tradicional de algunas de las piezas conservadas casi en su estado original. Por otra parte, el diseño de aportaciones nuevas que permitieran optimizar el nuevo uso público y, también, hacer lectura homogénea de "fragmentos" arquitectónicos que hasta entonces carecían de vínculos de relación.

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.

  5. GPS Imaging of Sierra Nevada Uplift

    2015-12-01

    Recent improvements in the scope and precision of GPS networks across California and Nevada have allowed for uplift of the Sierra Nevada to be observed directly. Much of the signal, in the range of 1 to 2 mm/yr, has been attributed to lithospheric scale rebound following massive groundwater withdrawal in the San Joaquin Valley in southern California, exacerbated by drought since 2011. However, natural tectonic deformation associated with long term uplift of the range may also contribute to the observed signal. We have developed new algorithms that enhance the signal of Sierra Nevada uplift and improve our ability to interpret and separate natural tectonic signals from anthropogenic contributions. We apply our new Median Interannual Difference Adjusted for Skewness (MIDAS) algorithm to the vertical times series and a inverse distance-weighted median spatial filtering and Delaunay-based interpolation to despeckle the rate map. The resulting spatially continuous vertical rate field is insensitive to outliers and steps in the GPS time series, and omits isolated features attributable to unstable stations or unrepresentative rates. The resulting vertical rate field for California and Nevada exhibits regionally coherent signals from the earthquake cycle including interseismic strain accumulation in Cascadia, postseismic relaxation of the mantle from recent large earthquakes in central Nevada and southern California, groundwater loading changes, and tectonic uplift of the Sierra Nevada and Coast Ranges. Uplift of the Sierra Nevada extends from the Garlock Fault in the south to an indefinite boundary in the north near the latitude of Mt. Lassen to the eastern Sierra Nevada range front in Owen's Valley. The rates transition to near zero in the southern Walker Lane. The eastern boundary of uplift coincides with the highest strain rates in the western Great Basin, suggesting higher normal fault slip rates and a component of tectonic uplift of the Sierra Nevada.

    Whole-rock geochemical analyses using major and trace elements in combination with the Sm-Nd and Pb-Pb isotope systems, together with SHRIMP age dating on metasedimentary rocks from the Sierras de Chepes, the Sierras de Córdoba, the Sierra Norte and the San Luis Formation in the Sierra de San Luis, have been carried out to unravel the provenance and the geodynamic history of the Eastern Sierras Pampeanas, Central Argentina. The geochemical and the Sm-Nd data point to a slightly stronger mafic and less-fractionated material in the provenance area of the Sierras de Córdoba when compared to the other units. The TDM model ages from the Sierras de Chepes (~1.82 Ga) and the Sierra Norte (~1.79 Ga) are significantly older than the data from the Sierras de Córdoba (1.67 Ga). The Pb data are homogeneous for the different units. Only the 208Pb/204Pb ratios of some samples from the Sierras de Córdoba are higher. A late Pampean detrital zircon peak around 520 Ma from the Sierras de Chepes is in accordance with the new data from the San Luis Formation. This is similar to the literature data from the Famatina Belt located to the northwest of the Sierras de Chepes and also fits the detrital zircon peaks in the Mesón group. These maximum depositional ages were also reported from some locations in the Puncoviscana Formation but are absent in the Sierras de Córdoba. An improved model for the development of the Eastern Sierras Pampeanas in the area between the Sierras de Córdoba and the Puncoviscana Formation is provided. This gives new insights into the late Pampean development of the Sierra de San Luis and the complex development of the Eastern Sierras Pampeanas. This new model explains the younger detrital ages in the Puncoviscana Formation compared with the older ages of the Sierras de Córdoba. Another model of the Sierra de San Luis explains the younger depositional ages of the Pringles Metamorphic Complex and the San Luis Formation when compared to the Nogol

    Northern California contains the intersection of the NW moving Sierra Nevada block and the clockwise rotating Oregon block. Adding to the tectonic complexity of the region are the interactions of the Pacific plate, Basin and Range, California Coast Ranges, Mendocino fracture zone, San Andreas fault and the Juan de Fuca plate. Our research focuses on how the interactions of these features influence the motions of the Oregon and Sierra Nevada blocks. We processed Global Positioning System (GPS) data collected during the 1998 and 1999 National Geodetic Survey High Accuracy Reference Network (HARN) surveys and by us in 2003. Our preliminary analysis of the velocity field indicates that the Oregon crustal block is rotating clockwise relative to the Sierra Nevada block around a pole approximately west of the Mendocino Triple Junction. Our future work involves finding a more exact location of the relative pole rotation between the blocks, the degree of rotation, and how this motion is being taken up.

    Systematic 40Ar/39Ar feldspar data obtained from the Sierras Pampeanas are presented, filling the gap between available high- (> 300 °C) and low-temperature (< 150 °C) thermochronological data. Results show Silurian-Devonian exhumation related to the late stages of the Famatinian/Ocloyic Orogeny for the Sierra de Pocho and the Sierra de Pie de Palo regions, whereas the Sierras de San Luis and the Sierra de Comechingones regions record exhumation during the Carboniferous. Comparison between new and available data points to a Carboniferous tectonic event in the Sierras Pampeanas, which represents a key period to constrain the early evolution of the proto-Andean margin of Gondwana. This event was probably transtensional and played a major role during the evolution of the Paganzo Basin as well as during the emplacement of alkaline magmatism in the retroarc.

    Full Text Available When originally published at the turn of the century, 'Pedro and Me: Friendship, Loss, and What I Learned' (2000 was riding both the popularity of its reality television roots ''and the growing awareness of homosexuality in the popular consciousness. At that time, too, Macmillan publisher Henry Holt had its own website set up to support Winick’s work; it featured interviews, tour dates, and, most importantly, omitted scenes originally drafted but not completed by the author. The opportunity to finally include this apocrypha was missed in the newer 2009 addition, as the publisher opted for a one-page afterword.  This paper discusses how this constitutes a missed opportunity to reconnect with Pedro. In as much as the original graphic novel—or 'any' graphic novel—is a construction, the tenth anniversary edition of 'Pedro and Me' disallowed the excluded raw material from being included in audience’s score-overdue deconstruction of the work.

    Full Text Available When originally published at the turn of the century, Pedro and Me: Friendship, Loss, and What I Learned (2000 was riding both the popularity of its reality television roots and the growing awareness of homosexuality in the popular consciousness. At that time, too, Macmillan publisher Henry Holt had its own website set up to support Winick’s work; it featured interviews, tour dates, and, most importantly, omitted scenes originally drafted but not completed by the author. The opportunity to finally include this apocrypha was missed in the newer 2009 addition, as the publisher opted for a one-page afterword.  This paper discusses how this constitutes a missed opportunity to reconnect with Pedro. In as much as the original graphic novel—or any graphic novel—is a construction, the tenth anniversary edition of Pedro and Me disallowed the excluded raw material from being included in audience’s score-overdue deconstruction of the work.

    RÉSUMÉ But : Effectuer une traduction franco-canadienne de la PEDro scale sous l'appellation proposée d'Échelle PEDro et examiner la validité de son contenu. Méthodologie : Nous avons utilisé une approche modifiée de la méthodologie de validation transculturelle de Vallerand. Une traduction renversée parallèle de la PEDro scale a d'abord été effectuée à la fois par des traductrices professionnelles et des chercheurs cliniciens. Ensuite, un premier comité d'experts (P1) a examiné les versions traduites et a créé la première version expérimentale de l'Échelle PEDro. Cette version a été évaluée par un deuxième comité d'experts (P2). Finalement, 32 chercheurs cliniques ont évalué cette deuxième version expérimentale de l'Échelle PEDro à l'aide d'une échelle de clarté (étendue de 5 points) et ont proposé les modifications finales. Résultats : Pour les différents énoncés de la version finale de l'Échelle PEDro, les moyennes sur l'échelle de clarté montrent un niveau élevé puisqu'elles varient entre 4,0 et 4,7 sur un score maximal de 5 points. Conclusion : Les quatre étapes rigoureuses du processus ont permis de produire une version franco-canadienne valide de l'Échelle PEDro. PMID:26839449

    1998-06-01

    In 1763 Pedro de Horta was requested by the prioress of the convent of San Gerónimo in Puebla de los Angeles to draw up a report to establish whether the epidemic of queer turns, violent shaking or epilepsy which affected the novices was caused by the Devil or was due to natural causes. Pedro de Horta, a doctor qualified in Mexico, methodically and thoroughly prepared an extensive monographic treatise on the illness which included all that was known at the time. The report showed the fierce debates provoked by the subject of epilepsy in the eighteenth century regarding whether it was of natural or supernatural origin. It also contained detailed accounts of the episodes, their causes and treatment. The Spaniard Pedro de Horta should be justly recognized as the first American epileptologist.

    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).

    This report summarizes computational efforts to model interfacial fracture using cohesive zone models in the SIERRA/SolidMechanics (SIERRA/SM) finite element code. Cohesive surface elements were used to model crack initiation and propagation along predefined paths. Mesh convergence was observed with SIERRA/SM for numerous geometries. As the funding for this project came from the Advanced Simulation and Computing Verification and Validation (ASC V&V) focus area, considerable effort was spent performing verification and validation. Code verification was performed to compare code predictions to analytical solutions for simple three-element simulations as well as a higher-fidelity simulation of a double-cantilever beam. Parameter identification was conducted with Dakota using experimental results on asymmetric double-cantilever beam (ADCB) and end-notched-flexure (ENF) experiments conducted under Campaign-6 funding. Discretization convergence studies were also performed with respect to mesh size and time step and an optimization study was completed for mode II delamination using the ENF geometry. Throughout this verification process, numerous SIERRA/SM bugs were found and reported, all of which have been fixed, leading to over a 10-fold increase in convergence rates. Finally, mixed-mode flexure experiments were performed for validation. One of the unexplained issues encountered was material property variability for ostensibly the same composite material. Since the variability is not fully understood, it is difficult to accurately assess uncertainty when performing predictions.

    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.

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

    Arsenic (As) is a naturally occurring constituent in low-sulphide gold-quartz vein deposits, the dominant deposit type for lode mines in the Sierra Nevada Foothills (SNFH) gold (Au) province of California. Concentrations of naturally occurring mercury (Hg) in the SNFH Au province are low, but extensive use and loss of elemental Hg during amalgamation processing of ore from lode and placer Au deposits led to widespread contamination of Hg in the Sierra Nevada foothills and downstream areas, such as the Sacramento–San Joaquin Delta and San Francisco Bay. This review paper provides an overview of As and Hg contamination related to historical Au mining in the Sierra Nevada of California. It summarizes the geology, mineralogy, and geochemistry of the Au deposits, and provides information on specific areas where detailed studies have been done in association with past, ongoing, and planned remediation activities related to the environmental As and Hg contamination.Arsenic is a naturally occurring constituent in low-sulphide Au-quartz vein deposits, the dominant deposit type for lode mines in the Sierra Nevada Foothills (SNFH) Au province (Ashley 2002). Because of elevated concentrations of As in accessory iron-sulphide minerals including arsenopyrite (FeAsS) and arsenian pyrite (Fe(S,As)2), As is commonly a contaminant of concern in lode Au mine waste, including waste rock and mill tailings. The principal pathways of human As exposure from mine waste include ingestion of soil or drinking water, and inhalation of dust in contaminated areas (Mitchell 2014).Concentrations of naturally occurring Hg in the SNFH Au province are low, but extensive use and loss of elemental Hg during amalgamation processing of ore from lode and placer Au deposits (Churchill 2000) led to widespread contamination of Hg in the Sierra Nevada foothills and downstream areas, such as the Sacramento–San Joaquin Delta and San Francisco Bay (Alpers et al. 2005a).

    Navarro, A.; Diaz, F.; Rodriguez, I. [S.A., Maraven (Venezuela)

    1996-08-01

    The study area is located in the Costa Bolivar (onshore) in the Maracaibo Basin, being framed by Ceuta (offshore) and Tomoporo fields to its west and the Valera fault zone to the east, Mene Grande field to the north and La Ceiba to the south. Eocene oil accumulations are the most important for the study area. Probably this oil was generated and migrated during Miocene-Holocene time. Heavy oil accumulations occur in Miocene intervals, although they have not been considered commercial. It is possible that this oil was generated during early to late Eocene and suffered later biodegradation and remigration. Structurally, it is characterized by different and highly complex tectonic events. Normal faulting occurred during Cretaceous and Eocene times. During the latter, periods of inversion were present that created structural highs where oil generated from La Luna Formation (Cretaceous) accumulated. Major structural deformation occurred during upper Eocene and lower Miocene (Andes uplift). This deformation shows an increase from west (Barua) to east where the Valera fault zone is present. The study area shows a regional dip towards the south, while during the Eocene it dipped towards the north, due to the foredeep condition of the area, when up to 15,000 ft of sediments were deposited, based on seismic data. Porosities vary from 8% to 18% within the area. Fractures are present and they enhance oil production.

    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.

    Full Text Available 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.

    The Cretin iCOE project has a goal of enabling the efficient generation of Non-LTE opacities for use in radiation-hydrodynamic simulation codes using the Nvidia boards on LLNL’s upcoming Sierra system. Achieving the desired level of accuracy for some simulations require the use of a vary large number of atomic configurations (a configuration includes the atomic level for all electrons and how they are coupled together). The NLTE rate matrix needs to be solved separately in each zone. Calculating NLTE opacities can consume more time than all other physics packages used in a simulation.

    Full Text Available Amphibians from Sierras Pampeanas Centrales of Argentina: diversity and altitudinal distribution. Sierras Pampeanas Centrales (SPC mountains are located in Córdoba and San Luis provinces (Argentina and represent an area of unique biogeographic importance. In this paper we provide a synthesis about the knowledge of diversity and altitudinal distribution of anurans that inhabit SPC mountains. We compiled a species list through different information sources (field data, biological collections and bibliography. Using this information we characterize altitudinal distribution range of each species and analyze associations between species richness and composition and altitude gradient. We recorded 24 amphibians species belonging to five families. These species are heterogeneously distributed over the altitude gradient of SPC. We detect a linear negative relationship between altitude and species richness and defined assemblages associated with different altitude sectors. The results obtained in the paper represent basic information that will be useful to evaluate anthropogenic impact on this particular and fragile mountain system.

    Full Text Available Several species of frogs and toads are in serious decline in the Sierra Nevada Mountains of California. These species include the threatened red-legged frog (Rana aurora, foothill yellow-legged frog (R. boylii, mountain yellow-legged frog (R. muscosa, Cascades frog (Rana cascadae, western toad (Bufo boreas and Yosemite toad (B. canorus. For many of these species current distributions are down to 10% of historical ranges [1,2]. Several factors including introduced predators [3,4,5], habitat loss [2], and ultraviolet radiation [6] have been suggested as causes of these declines. Another probable cause is air-borne pesticides from the Central Valley of California. The Central Valley, especially the San Joaquin Valley, is a major agricultural region where millions of pounds of active ingredient pesticides are applied each year (http://www.cdpr.ca.gov/dprdatabase.htm. Prevailing westerly winds from the Pacific Coast transport these pesticides into the Sierras [7,8].

    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. 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. 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. 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. 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.

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

    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 El vidrio es uno de los materiales que ha alcanzado una dimensión escultórica en el siglo XX. Fue a mediados de este siglo, aproximadamente, cuando tuvo lugar su incorporación a la escultura contemporánea, y aunque España se ha sumado con un cierto retraso a esta nueva vertiente del lengueje escultórico, no son pocos los nombres de escultores que podrían ser citados por haber descubierto las posibilidades que el vidrio encierra como material escultórico. Uno de ellos es Pedro García, quien ha encontrado en el vidrio laminado, un material de procedencia industrial, su medio de expresión plástica. El análisis de su evolución artística hasta el momento actual constituye el objeto de este artículo, para lo cual se ha partido de unas primeras obras que obedecen a un planteamiento constructivo, racionalista, y en las que el vidrio ha sido trabajado en frío.The apparition of glass as a new material in sculpture dates from the middle of the XXth century. Spain has incorporated the sculptoric possibilities of glass later than other countries, but it has had an important following by an important group of sculptors. One of them is Pedro García, who has found in laminated glass, an industrial type of glass, his chief inspiration. This article traces the history of his artistic evolution. In the beginning his sculptures were very constructive and rational. Later, he developed a special technique working on glass in the process of formation through heat.

    2015-01-01

    We conducted surveys for the Endangered Sierra Madre yellow-legged frog Rana muscosa throughout southern California to evaluate the current distribution and status of the species. Surveys were conducted during 2000–2009 at 150 unique streams and lakes within the San Gabriel, San Bernardino, San Jacinto, and Palomar mountains of southern California. Only nine small, geographically isolated populations were detected across the four mountain ranges, and all tested positive for the amphibian chytrid fungus Batrachochytrium dendrobatidis. Our data show that when R. muscosa is known to be present it is easily detectable (89%) in a single visit during the frog's active season. We estimate that only 166 adult frogs remained in the wild in 2009. Our research indicates that R. muscosa populations in southern California are threatened by natural and stochastic events and may become extirpated in the near future unless there is some intervention to save them.

    The impact of armed conflict on the environment is of major public policy importance. We use a geographically disaggregated dataset of civil war violence together with satellite imagery of land cover to test whether war facilitated or prevented forest loss in Sierra Leone. The conflict data set allows us to establish where rebel groups were stationed and where battles and attacks occurred. The satellite data enables to us to monitor the change in forest cover (total, primary, and secondary) in all of Sierra Leone’s 151 chiefdoms, between 1990 (prior to the war) and 2000 (just prior to its end). The results suggest that conflict in Sierra Leone acted as a brake on local deforestation: conflict-ridden areas experienced significantly less forest loss relative to their more conflict-free counterparts.

    Full Text Available This paper shows the use and value of natural resources from a social, sustainable and legal perspective, under the scheme of Sustainable Forest Management Units (UMAFOR by its Spanish acronym. Two participatory workshops were carried out in March 2010, one in UMAFOR Sierra La Madera and another in UMAFOR Sierra Alta, belonging to the Sierra de Sonora. An adaptation of “Problems, Causes and Consequences” of Ramírez-García (2004 methodology was used to discuss issues such as conservation, productive activities, society, laws, research and support programs. The objective was to analyze challenges and opportunities in the Sierra de Sonora under this management scheme. The ratting of natural resource for inhabitant and producers was documented based in ecosystems type and its value for use. Economic value was the most important for productive and non productive use; however, there are opportunities to transit from traditional to sustainable activities. Local producers are interested in linking whit research centers and consultants to get support for diversification of productive activities. It is possible to have changes according to sustainable development; UMAFOR is an alternative to achieve those changes.

    The hydraulic gold-mining process used during the California Gold Rush and in many developing countries today contributes enormous amounts of sediment to rivers and streams. Commonly, accompanying this sediment are contaminants such as elemental mercury and cyanide used in the gold extraction process. We show that some of the mercurycontaminated sediment created by hydraulic gold mining in the Sierra Nevada, between 1852 and 1884, ended up over 250 kilometers (km) away in San Francisco Bay; an example of the far-reaching extent of contamination from such activities.

    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.

    Full Text Available 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.

    In 2012, Sierra Leone experienced its worst cholera outbreak in over 15 years affecting 12 of the country's 13 districts. With limited diagnostic capability, particularly in bacterial culture, the cholera outbreak was initially confirmed by microbiological testing of clinical specimens outside of Sierra Leone. During 2012 - 2013, in direct response to the lack of diagnostic microbiology facilities, and to assist in investigating and monitoring the cholera outbreak, diagnostic and reference services were established in Sierra Leone at the Central Public Health Reference Laboratory focusing specifically on isolating and identifying Vibrio cholerae and other enteric bacterial pathogens. Sierra Leone is now capable of confirming cholera cases by reference laboratory testing.

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.

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.

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.

  18. Transient thermal regimes in the Sierra Nevada and Baja California extinct outer arcs following the cessation of Farallon subduction

    Science.gov (United States)

    Erkan, Kamil; Blackwell, David

    2009-02-01

    We examine the thermal relaxation of the Sierra Nevada and Baja California extinct outer arc blocks following the progressive cessation of Farallon subduction under western North America beginning at ˜30 Ma. Being parts of the same outer arc until the inland jump of the San Andreas transform fault at ˜5 Ma, these two regions show many similarities in their geology, geomorphology, rigid body behavior, and their relatively low seismicity. In the thermal model, we combine results of different geophysical and geophysical studies to constrain the thermal state and geometry of the outer arcs before the cessation of subduction and then model the postsubduction temperature responses in these regions using the results of the tectonic reconstructions. A well-constrained regional thermal model of these blocks using the results of many earlier studies in these regions confirms that the present low heat flow values in these regions are the remnants of the very cold outer arc thermal regime of the subduction zone even as long as 30 Ma after cessation of subduction. Thus the entire Pacific boundary of the North American plate is still in a transient thermal state. The calculated low lithospheric temperatures in the Sierra Nevada and Peninsular blocks correlate very well with their rigid body behavior obtained from geodetic studies, and seismogenic layer thicknesses obtained from seismological studies. This is in contrast with the fact that both regions are surrounded by intense deformation associated with the western North America intraplate and extraplate motions. These low-temperature islands play important roles in the present interaction of the North American and Pacific plates and contribute to the broad deformation of the transform boundary. The thermal relaxation of the extinct outer arcs includes both vertical heating from the underlying asthenosphere and the lateral heating from the extinct back arc (Basin and Range), which has remained as a high heat flow region after

    Full Text Available La Sierra de la Culebra se presenta como un espacio de profundas transformaciones en su fi sonomía vegetal a lo largo de una prolongada evolución temporal. El agente causante de estos cambios ha sido el ser humano, que, de manera directa o indirecta, ha eliminado las especies forestales, o facilitado la sustitución de unas especies forestales por otras, creando así un medio de alta estabilidad de la vegetación. Se estudia aquí el resultado de esta dinámica de la vegetación en dos momentos signifi cativos de la evolución, el siglo XVIII y el siglo XX. En la primera fecha nos encontramos con un paisaje vegetal ya ampliamente modelado por el hombre, con un predominio de los matorrales de brezo, a través de la implantación de una determinada estructura económica. Mientras que en la segunda mitad del siglo XX serán agentes externos al espacio serrano los que fuerzan una nueva dinámica, a partir de la introducción de nuevas especies forestales, las coníferas, hasta ese momento ajenas al devenir histórico de la Sierra. Esta nueva orientación que se da al espacio de la Sierra está en relación con una estructura económica distinta a la que tradicionalmente se había puesto en práctica en la zona.

    Full Text Available The shallow-sea hydrothermal vents at White Point (WP in Palos Verdes (PV 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.

The inventory of birds are refers to studies in near areas. This study is a concrete contribution of the birds of the mountain chain and north of it. We considered bibliographic records and databases available on the web with records of ocurrence and specimens of scientific collections. Also we perform point counts in different localities inside the reserve. We observed a richness of 261 birds species, the family Tyrannidae is the best represented. Of the species recorded, 177 are permanent residents (31 are endemic and 15 are quasi-endemics to Mexico and 73 are migratory; the remaining eleven records have other status. Also 43 species are in endangered categories. We include species that have not been recorded in the lists of the area and records of species expand their ranges at Nayarit. Due to the great diversity of birds observed, it is necesary to continue the research work about habitat use, abundance and monitoring, it will provides the basis for the conservation of birds of Sierra de Vallejo.

    Based on 2431 captures of 757 individual frogs over a 9-yr period, we found that the population of R. sierrae in one meadow–stream complex in Yosemite National Park ranged from an estimated 45 to 115 adult frogs. Rana sierrae at our relatively low elevation site (2200 m) grew at a fast rate (K = 0.73–0.78), had high overwintering survival rates (44.6–95%), lived a long time (up to 16 yr), and tended to be fairly sedentary during the summer (100% minimum convex polygon annual home ranges of 139 m2) but had low year-to-year site fidelity. Even though the amphibian chytrid fungus (Batrachochytrium dendrobatidis, Bd) has been present in the population for at least 13 yr, there was no clear downward trend as might be expected from reports of R. sierrae population declines associated with Bd or from reports of widespread population decline of R. sierrae throughout its range.

    Polymers and fiber-reinforced polymer matrix composites play an important role in many Defense Program applications. Recently an advanced nonlinear viscoelastic model for polymers has been developed and incorporated into ADAGIO, Sandia's SIERRA-based quasi-static analysis code. Standard linear elastic shell and continuum models for fiber-reinforced polymer-matrix composites have also been added to ADAGIO. This report details the use of these models for advanced adhesive joint and composites simulations carried out as part of an Advanced Simulation and Computing Advanced Deployment (ASC AD) project. More specifically, the thermo-mechanical response of an adhesive joint when loaded during repeated thermal cycling is simulated, the response of some composite rings under internal pressurization is calculated, and the performance of a composite container subjected to internal pressurization, thermal loading, and distributed mechanical loading is determined. Finally, general comparisons between the continuum and shell element approaches for modeling composites using ADAGIO are given.

    Full Text Available This paper is based on documentation from Casa de Fontefiz kept in the AHPOR. 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.

  4. Selected streambed sediment compounds and water toxicity results for Westside Creeks, San Antonio, Texas, 2014

    Crow, Cassi L.; Wilson, Jennifer T.; Kunz, James L.

    2016-12-01

    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

    Full Text Available Here we describe a new species of Trachymyrmex, T. pakawa sp. n., from the Gran Sierra Plegada range of the Sierra Madre Oriental, in the states of Coahuila and Nuevo Leon, northeastern Mexico. Trachymyrmex pakawa is a large-sized species compared to other North American Trachymyrmex. Its geographic distribution includes the piedmont of the Gran Sierra Plegada at La Estanzuela, Monterrey, as well as peripheral mountains segregated from the Sierra Madre Oriental (Cerro de las Mitras, Sierra de Zapalinamé, Cañon de San Lorenzo, Cerro de las Letras. The preferred habitats of T. pakawa include oak-pine forest at La Estanzuela, xeric oak forest at Zapalinamé and mesic Chihuahuan desert scrub with sotol (Dasylirion at other sites. All localities are on slopes, on very rocky, shallow lithosols overlaying large boulders. This species nests under and between large boulders and rocks. It has not been observed on alluvial or better developed, deeper soils, and it is absent from sites with human activity (urban, disturbed, and landscaped areas. It is closely related to and morphologically similar to Trachymyrmex smithi. The known distribution ranges of T. pakawa and T. smithi almost overlap in Saltillo, Coahuila state. The main character that distinguishes the new species from T. smithi is longer antennal scapes in T. pakawa; also, different nesting habits (rocky slopes vs. alluvial sites or deep sand in T. smithi, and geographic distribution. Phylogenetic analysis of DNA sequences from the mitochondrial marker cytochrome c oxidase subunit I (COI and the first intron of the F1 copy of the nuclear protein-coding gene Elongation Factor 1- α (EF1-α-F1 confirm a sister-species relationship between T. pakawa and T. smithi.

    Crow, Cassi L.; Wilson, Jennifer T.; Kunz, James L.

    2016-12-01

    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 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. También confiscó los papeles de otros miembros de su círculo. En este artículo examino los dos textos más importantes: Sobre el pergamino y láminas de Granada de Valencia y un Libelo segundo de Francisco de Gurmendi, intérprete en lenguas orientales del rey. El artículo se centra en la respuesta de Gurmendi a un memorial del Arzobispo Pedro de Castro en el que se defiende a uno de sus traductores. Partiendo de su traducción de los dos primeros libros plúmbeos, Gurmendi muestra las herejías trinitarias que éstos contienen y cómo el memorialista ha traducido mal muchos pasajes.

    2004-09-01

    Full Text Available Abstract Background Proteomics is rapidly evolving into a high-throughput technology, in which substantial and systematic studies are conducted on samples from a wide range of physiological, developmental, or pathological conditions. Reference maps from 2D gels are widely circulated. However, there is, as yet, no formally accepted standard representation to support the sharing of proteomics data, and little systematic dissemination of comprehensive proteomic data sets. Results This paper describes the design, implementation and use of a Proteome Experimental Data Repository (PEDRo, which makes comprehensive proteomics data sets available for browsing, searching and downloading. It is also serves to extend the debate on the level of detail at which proteomics data should be captured, the sorts of facilities that should be provided by proteome data management systems, and the techniques by which such facilities can be made available. Conclusions The PEDRo database provides access to a collection of comprehensive descriptions of experimental data sets in proteomics. Not only are these data sets interesting in and of themselves, they also provide a useful early validation of the PEDRo data model, which has served as a starting point for the ongoing standardisation activity through the Proteome Standards Initiative of the Human Proteome Organisation.

    full text: Several species of anuran amphibians (frogs and toads) are experiencing severe population declines in even seemingly pristine areas of the Sierra Mountains of California. Among the most severely depressed species are the redlegged frog, the foothill and mountain yellow-legged frogs, the Yosemite toad, and the Cascades frog. Several factors, such as habitat fragmentation, introduced predators (especially fish), and disease, have been linked to these declines. But recent evidence from a USGS-led study shows that contaminants are a primary factor. During the past three years, researchers from the USGS Patuxent Wildlife Research Center, the Western Ecology Research Center, the USDA Beltsville Agriculture Research Center, and the Texas A&M University have teamed up to conduct an extensive study on airborne pesticides and their effects on amphibian populations in the Sierra Nevada Mountains. Previous work on environmental chemistry demonstrated that pesticides from the intensely agricultural Central Valley of California are being blown into the more pristine Sierra Nevada Mountains, especially around Sequoia and Yosemite National Parks. Several pesticides, including diazinon, chlorpyrifos, malathion and endosulfan, can be measured in snow, rainfall, and pond waters in these national parks. With the exception of endosulfan, these pesticides affect and even kill both invertebrates and vertebrate species by inhibiting cholinesterase, an enzyme essential to proper nervous system functioning. In the summer of 2001, we published a paper showing that these same pesticides are now found in adults and the tadpoles of Pacific treefrogs. The results of this landmark study showed that more than 50 percent of the tadpoles and adults sampled in Yosemite and Sequoia National Parks had detectable levels of diazinon or chlorpyrifos and that 86 percent of the Pacific treefrogs sampled in the Lake Tahoe region had detectable levels of endosulfan. In contrast, frogs that were

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

  3. Ammonia at Blodgett Forest, Sierra Nevada, USA

    2007-11-06

    Ammonia is a reactive trace gas that is emitted in large quantities by animal agriculture and other sources in California, which subsequently forms aerosol particulate matter, potentially affecting visibility, climate, and human health. We performed initial measurements of NH{sub 3} at the Blodgett Forest Research Station (BFRS) during a two week study in June, 2006. The site is used for ongoing air quality research and is a relatively low-background site in the foothills of the Sierra Nevada. Measured NH{sub 3} mixing ratios were quite low (< 1 to {approx} 2 ppb), contrasting with typical conditions in many parts of the Central Valley. Eddy covariance measurements showed NH{sub 3} fluxes that scaled with measured NH{sub 3} mixing ratio and calculated aerodynamic deposition velocity, suggesting dry deposition is a significant loss mechanism for atmospheric NH{sub 3} at BFRS. A simple model of NH{sub 3} transport to the site supports the hypothesis that NH{sub 3} is transported from the Valley to BFRS, but deposits on vegetation during the summer. Further work is necessary to determine whether the results obtained in this study can be generalized to other seasons.

    Orthopoxviruses, including variola virus, vaccinia virus, and monkeypox virus, have previously been documented in humans in West Africa, however, no cases of human orthopoxvirus infection have been reported in the region since 1986. We conducted a serosurvey to determine whether human exposure to orthopoxviruses continues to occur in eastern Sierra Leone. To examine evidence of exposure to orthopoxviruses in the Kenema District of Sierra Leone, we collected and tested sera from 1596 persons by IgG ELISA and a subset of 313 by IgM capture ELISA. Eleven persons born after the cessation of smallpox vaccination had high orthopoxvirus-specific IgG values, and an additional 6 persons had positive IgM responses. No geographic clustering was noted. These data suggest that orthopoxviruses continue to circulate in Sierra Leone. Studies aimed at obtaining orthopoxvirus isolates and/or genetic sequences from rodents and symptomatic humans in the area are indicated.

    2014-06-01

    Full Text Available The Sierra de Lujar constitutes one of the best examples of fold superposition of the Internal Zone of the Betic Cordillera (S Spain. In this paper, the members of its Triassic carbonate series have been used for the first time to obtain the cartography of the Sierra de Lujar, providing knowledge of the two folding systems, the older trending E-W and the younger (far better represented, NNE-SSW. The most important fold is a large reverse syncline with a convex axis towards the SE, forming part of the S and E edges of this sierra; contrarily, the vergence is towards the N in the southern sector and towards the W in the eastern sector. The interior of the Sierra de Lujar bears a succession of NNE-SSO anticlinal and synclinal folds, some with reverse limbs. The vergences fluctuate, even within the same fold. Folds of an E-W system crop out only in the SW sector of the Sierra de Lujar and verge to the S. The unit of the Sierra de Lujar (Lujar-Gádor unit is overthrust by the Escalate unit (which is a duplication of the Lujar unit and by other upper units, formed here by schists. The W edge of the Sierra de Lujar is affected by a large normal fault that sinks the Escalate unit there. The E-W folds were coetaneous with the thrusting of the units, while those in the NNE-SSW direction formed at the onset of the westward shift of the Internal Betic-Rif Zone.La Sierra de Lújar constituye uno de los mejores ejemplos de superposición de pliegues de la Zona Interna Bética.

  9. Investigating Causes and Consequences of 150 Years of Channel Morphology Evolution in San Pablo Bay, California

    2010-12-01

    The Delta is an area where rivers draining the Central Valley and Sierras of California, including the Sacramento and San Joaquin Rivers, meet before discharging into the northeastern end of the San Francisco Estuary. San Pablo Bay, a sub-embayment in the northern Estuary, is circular with an area of about 250 km2 and an average tidal range of about 1.5 m. It is rather shallow (depths generally less than 4 m, average depth San Pablo Bay has changed markedly since the Gold Rush. Deposition of more than a quarter billion cubic meters of hydraulic gold mining debris reduced the average depth of San Pablo Bay by 85 cm in the middle and late 1800s. In the late 1900s the intertidal flats narrowed and the major channel in the Bay deepened as more sediment was lost to the sea than entered from rivers. Processes of sediment redistribution caused the main channel to become narrower as well, a trend observed over the last 150 years. It is not clear what is causing the change in channel geometry and the implications of the change in geometry on the seaward transport of sediment through San Pablo Bay. This study investigates the cause of this channel geometry development and its impact on the conveyance of sediment through and distribution within San Pablo Bay using a process-based, numerical model (Delft3D). The Delft3D model developed for this study is a 3D model that includes the k-ɛ turbulence model, wind, waves, multiple mud and sand fractions and salt-fresh water density differences, as well as schematized tidal and river flow boundary conditions. The approach is to perform different runs with equal forcing on different historic bathymetries. By keeping the bed in a fixed, non-erodible state, we can analyze the impact of the evolving San Pablo Bay morphology on the conveyance efficiency of water and sediments. Model results show what happens with sediment supplied by the Sacramento River and San Joaquin River as well as the behavior of different sediment classes on

  10. Heavy mineral analysis for assessing the provenance of sandy sediment in the San Francisco Bay Coastal System

    Wong, Florence L.; Woodrow, Donald L.; McGann, Mary

    2013-01-01

    Heavy or high-specific gravity minerals make up a small but diagnostic component of sediment that is well suited for determining the provenance and distribution of sediment transported through estuarine and coastal systems worldwide. By this means, we see that surficial sand-sized sediment in the San Francisco Bay Coastal System comes primarily from the Sierra Nevada and associated terranes by way of the Sacramento and San Joaquin Rivers and is transported with little dilution through the San Francisco Bay and out the Golden Gate. Heavy minerals document a slight change from the strictly Sierran-Sacramento mineralogy at the confluence of the two rivers to a composition that includes minor amounts of chert and other Franciscan Complex components west of Carquinez Strait. Between Carquinez Strait and the San Francisco Bar, Sierran sediment is intermingled with Franciscan-modified Sierran sediment. The latter continues out the Gate and turns southward towards beaches of the San Francisco Peninsula. The Sierran sediment also fans out from the San Francisco Bar to merge with a Sierran province on the shelf in the Gulf of the Farallones. Beach-sand sized sediment from the Russian River is transported southward to Point Reyes where it spreads out to define a Franciscan sediment province on the shelf, but does not continue southward to contribute to the sediment in the Golden Gate area.

It provides capabilities for explicit dynamic and implicit quasistatic and dynamic analyses. The explicit dynamics capabilities allow for the efficient and robust solution of models subjected to large, suddenly applied loads. For implicit problems, Sierra/SM uses a multi-level iterative solver, which enables it to effectively solve problems with large deformations, nonlinear material behavior, and contact. Sierra/SM has a versatile library of continuum and structural elements, and an extensive library of material models. The code is written for parallel computing environments, and it allows for scalable solutions of very large problems for both implicit and explicit analyses. It is built on the SIERRA Framework, which allows for coupling with other SIERRA mechanics codes. This document describes the functionality and input structure for Sierra/SM.

    There are five areas with mineral resource potential and one area with geothermal energy potential in the South Sierra Wilderness and the South Sierra Roadless Area. The area south of Summit Meadows and the area south of Hogback Creek have moderate resource potential for tungsten and molybdenum in small skarn deposits. The area between Summit meadow and Hogback Creek and the area from south of Jackass Meadows to northwest of Granite Knob have low mineral resource potential for tungsten and molybdenum. The area south of and including Walker Creek has low mineral resource potential for lead and zinc. The area including and surrounding Monache Mountain has high geothermal energy resource potential.

    The discovery of a near complete skeleton of Mammuthus columbi in a cornfield located on the northern slopes of the Sierra Chichinautzin volcanic field south of Mexico City sparked the interest of the scientific and public community. Although remains of this species of mammoth are frequently discovered in central Mexico, this new find is at the southernmost and highest (ca. 2770 m asl) location yet within the Mexico Basin. In addition, the bones were found embedded in dark volcanic ash, raising the possibility of a relationship between the death of the animal and explosive activity at a neighboring scoria cone, as the site is located <10 km from several young volcanoes. Stratigraphic, sedimentological, geochemical, and geochronological studies were conducted at the discovery site and within a 5-km radius to determine the tephra stratigraphy in the area and constrain the source of the " mammoth ash" and the age and taphonomy of the fossil remains. Results show that the mammoth was buried after death by stream-flows (dilute lahars) that were triggered by torrential rain that remobilized loose scoriaceous ash ejected by the San Miguel cone some time after its eruption ca. 17,000 BP.

  10. Dam-induced Flow Changes, Sacramento and San Joaquin Rivers, California

    Kondolf, G. M.

    The Sacramento and San Joquin Rivers drain nearly 158,000 km of the Sierra_Nevada- Cascade Range, the Coast Range, and the intervening Central Valley, flowing west- ward through San Francisco Bay and Golden Gate to the Pacific. Numerous dams in the basin (for irrigation, hydroelectric power, and municipal/industry) all together im- pound 80% of the mean annual runoff in the Sacramento River basin, 120% in the San Joaquin River. I calculated the Impounded Runoff Index (IR), the reservoir stor- age capacity divided by the mean annual runoff for at least 12 sites on the channel. I analyzed changes in annual peak discharge and mean monthly flows since dam con- struction on the mainstem Sacramento San Joaquin and ten major tributaries for which suitable data were available. Ratios of post-to-pre-dam ranged from 0.72 (a 28% re- duction) to 0.006 (a 90% reduction). Reduction in peak flows was greater with higher values of IR, but the relations had scatter. Means monthly flows ranged from virtually no change pre-dam, to significant reductions in winter/spring high flows and increased the base flow.

    Many bibliographic databases index research studies evaluating the effects of health care interventions. One study has concluded that the Physiotherapy Evidence Database (PEDro) has the most complete indexing of reports of randomized controlled trials of physical therapy interventions, but the design of that study may have exaggerated estimates of the completeness of indexing by PEDro. The purpose of this study was to compare the completeness of indexing of reports of randomized controlled trials of physical therapy interventions by 8 bibliographic databases. This study was an audit of bibliographic databases. Prespecified criteria were used to identify 400 reports of randomized controlled trials from the reference lists of systematic reviews published in 2008 that evaluated physical therapy interventions. Eight databases (AMED, CENTRAL, CINAHL, EMBASE, Hooked on Evidence, PEDro, PsycINFO, and PubMed) were searched for each trial report. The proportion of the 400 trial reports indexed by each database was calculated. The proportions of the 400 trial reports indexed by the databases were as follows: CENTRAL, 95%; PEDro, 92%; PubMed, 89%; EMBASE, 88%; CINAHL, 53%; AMED, 50%; Hooked on Evidence, 45%; and PsycINFO, 6%. Almost all of the trial reports (99%) were found in at least 1 database, and 88% were indexed by 4 or more databases. Four trial reports were uniquely indexed by a single database only (2 in CENTRAL and 1 each in PEDro and PubMed). The results are only applicable to searching for English-language published reports of randomized controlled trials evaluating physical therapy interventions. The 4 most comprehensive databases of trial reports evaluating physical therapy interventions were CENTRAL, PEDro, PubMed, and EMBASE. Clinicians seeking quick answers to clinical questions could search any of these databases knowing that all are reasonably comprehensive. PEDro, unlike the other 3 most complete databases, is specific to physical therapy, so studies not

    2014-12-01

    Full Text Available O ensaio analisa as manifestações do idealismo de orientação romântica na poesia de Augusto dos Anjos e Pedro Kilkerry, visando, por um lado, evidenciar os pontos de contato existente entre as obras dos dois poetas, e por outro, demonstrar que muitos dos procedimentos estéticos inovadores de que eles se servem nascem em resposta a urgências oriundas de uma concepção idealista da poesia. Augusto dos Anjos e Pedro Kilkerry manifestam o anseio por depreender junto à realidade fenomênica conexões com uma esfera suprassensível, que, embora assuma contornos distintos em cada um dos poetas, parece remeter a uma visão comum de um ideal poético transcendente à realidade concreta. Em busca desse objetivo, Augusto dos Anjos e Kilkerry recorrem a procedimentos que atualizam a dicção poética do sublime romântico; o primeiro vale-se de um repertório filosófico híbrido, que imprime um prosaísmo tenso e inovador em sua poesia, ao passo que o segundo opta pela representação indireta, por meio de uma linguagem evocativa e metonímica, que assinala o mistério do ideal transcendente, sem, contudo, decifrá-lo.

Thereafter, a cross-section of girls and women (n = 258 attending antenatal care and Well Women Clinics in Bo Town, Bo District, in the southern region and in Makeni Town, Bombali District, in the northern region of Sierra Leone were randomly selected. Participants answered interview-administrated pretested structured questionnaires with open-ended-questions, administrated by trained female personnel.Results: All respondents had undergone FGM, most between 10 and 14 years of age. Complications were reported by 218 respondents (84.5%, the most common ones being excessive bleeding, delay in or incomplete healing, and tenderness. Fever was significantly more often reported by girls who had undergone FGM before 10 years of age compared with those who had undergone the procedure later. Out of those who reported complications, 187 (85.8% sought treatment, with 89 of them visiting a traditional healer, 75 a Sowei (traditional circumciser, and 16 a health professional.Conclusion: The high prevalence rate of FGM and the proportion of medical complications show that FGM is a matter for public health concern in Sierra Leone.

    Full Text Available Lassa fever (LF, an often-fatal hemorrhagic disease caused by Lassa virus (LASV, is a major public health threat in West Africa. When the violent civil conflict in Sierra Leone (1991 to 2002 ended, an international consortium assisted in restoration of the LF program at Kenema Government Hospital (KGH in an area with the world's highest incidence of the disease.Clinical and laboratory records of patients presenting to the KGH Lassa Ward in the post-conflict period were organized electronically. Recombinant antigen-based LF immunoassays were used to assess LASV antigenemia and LASV-specific antibodies in patients who met criteria for suspected LF. KGH has been reestablished as a center for LF treatment and research, with over 500 suspected cases now presenting yearly. Higher case fatality rates (CFRs in LF patients were observed compared to studies conducted prior to the civil conflict. Different criteria for defining LF stages and differences in sensitivity of assays likely account for these differences. The highest incidence of LF in Sierra Leone was observed during the dry season. LF cases were observed in ten of Sierra Leone's thirteen districts, with numerous cases from outside the traditional endemic zone. Deaths in patients presenting with LASV antigenemia were skewed towards individuals less than 29 years of age. Women self-reporting as pregnant were significantly overrepresented among LASV antigenemic patients. The CFR of ribavirin-treated patients presenting early in acute infection was lower than in untreated subjects.Lassa fever remains a major public health threat in Sierra Leone. Outreach activities should expand because LF may be more widespread in Sierra Leone than previously recognized.

    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

  18. Rangewide glaciation in the Sierra Nevada, California

    Science.gov (United States)

    Moore, James G.; Moring, Barry C.

    2013-01-01

    The 600-km-long Sierra Nevada underwent extensive Pleistocene glaciation except for its southernmost 100 km. Presently, ∼1700 small glaciers and ice masses near the crest of the range occur above 3250 m in elevation; these covered an area of ∼50 km2 in 1972. Fourteen of the largest glaciers decreased by about one half in area during the period from 1900 to 2004.Rock glaciers, generally glacial ice covered by 1–10 m of rockfall debris, occur in about the same span of the range as ice and permanent snowfields. They are, on average, lower by 200–300 m, apparently because of the insulating layer of rocky rubble that protects their internal ice from the sun’s heat and from wind.The principal Pleistocene glacial stages are the Sherwin (ca. 820 ka), Tahoe (170–130 and ca. 70 ka), Tioga (14–28 ka), and Recess Peak (13 ka). Some 7040 glacial lakes, produced primarily by quarrying from bedrock, were mostly exposed after recession of the Tioga glacial stage. The lakes largely mark the area of primary snow accumulation. Below the lower limit of the lakes, ice flowed downward into river-cut canyons, forming major trunk glaciers within the zone of ablation.The range is in general a westward-tilted block upfaulted on its east side. Therefore, the main late Pleistocene trunk glaciers (Tahoe/Tioga) west of the crest extend 25–60 km, whereas those east of the crest extend only 5–20 km. Because of higher precipitation northward, glacial features such as the toes of existing glaciers and rock glaciers, as well as the late season present-day snowline, all decrease in elevation northward. Likewise, the elevation of the lower limit of glacial lakes, an indication of the zone of snow accumulation during the late Pleistocene, decreases about the same degree.

    Full Text Available Gabriela Mistral and Pedro Aguirre Cerda made acquaintance of themselves in 1916. Since then, they maintained correspondence until 1941. The paper is based on a set of twenty-seven letters written by Gabriela Mistral to Pedro Aguirre Cerda from different places of the world, published in Mapocho journal in 1977. It also includes the Epistolario de Gabriela Mistral issued in the Epistolario de Pedro Aguirre Cerda (1938-1941 published by the Centro de Estudios Barros Arana. Finally, it incorporates a letter by Juana Aguirre de Aguirre to Mistral, dated in 1942. This is completed by different references that both of them made in their letters to other people. The paper reviews four aspects of the relation between Gabriela Mistral and Pedro Aguirre Cerda. The first topic is in regard to the poetess daily life aspects. A second question its related with Gabriela Mistral’s professional matters, specially the ones connected with her labor as an educator, as an international government employee and as a publicist of our country in other places of the world. The third issue is related to the poetess’s opinions concerning issues about Chilean politics. Finally, the fourth topic is in relation with subjects concerning Mistral’s private life and personal opinions.

    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.

    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.

    2017-11-01

    Full Text Available Pedro de Padilla’s Églogas pastoriles, bucolic book of virgilian extraction, diversify its configuration through the exercise of an eclectic imitatio, that canalizes the adoption of models foreign to pastoral tradition, amongst them Ovid, Boccaccio, Petrach, Sannazaro, Garcilaso and Fray Luis de León, incorporated with various imitative tactics. This paper shows the presence of two Ovid’s works, Remedia amoris and Fable of Narcissus (Metamorphoses, III, ls. 339-510, examples of heuristic imitatio, that allows to adapt the source to pastoral background, without disfiguring it. The Remedia amoris are object of a selective treatment, to be added as a marginal element to Silvano’ story. The Fable of Narcissus develops the ovidian myth, intermediated by the Alamanni’s Italian version, that also heads the Hernando de Acuña and Gregorio Silvestre’s recreations.

El tema gira alrededor de la invasión de Panamá, por parte del ejército estadounidense, con la intención de deponer a Manuel Noriega en 1989. El estudio se centra en el tema de la violencia y en la forma como se incorpora en la ficción dándole un carácter peculiar, por el tratamiento histórico del tema que logra alejarse de la narración historicista. Aunque lo narrado tiene un carácter verosímil, la narrativa es una obra de ficción estéticamente lograda que descubre una nueva dimensión existencial y onírica del evento histórico. This is a formal analysis of short stories in El otro lado del sueño, by Pedro Luis Prados. The main theme is the invasion of Panama by the U.S. army, with the intention of deposing Manuel Noriega in 1989. The study focuses on the theme of violence and on how it is incorporated into the work of fiction, giving these short stories unique character, due to their treatment of history which distinguishes them from historic fiction. Although the narrations have a verisimilar essence, the stories become an esthetic work of fiction that exhibits a new oneiric and existential dimension of the historical events.

    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.

    Lassa virus (LASV) is endemic to parts of West Africa and causes highly fatal hemorrhagic fever. The multimammate rat (Mastomys natalensis) is the only known reservoir of LASV. Most human infections result from zoonotic transmission. The very diverse LASV genome has 4 major lineages associated with different geographic locations. We used reverse transcription PCR and resequencing microarrays to detect LASV in 41 of 214 samples from rodents captured at 8 locations in Sierra Leone. Phylogenetic analysis of partial sequences of nucleoprotein (NP), glycoprotein precursor (GPC), and polymerase (L) genes showed 5 separate clades within lineage IV of LASV in this country. The sequence diversity was higher than previously observed; mean diversity was 7.01% for nucleoprotein gene at the nucleotide level. These results may have major implications for designing diagnostic tests and therapeutic agents for LASV infections in Sierra Leone.

    Atmospherically deposited contaminants in the Sierra Nevada mountains of California, USA have been implicated as adversely affecting amphibians and fish, yet little is known about the distributions of contaminants within the mountains, particularly at high elevation. We tested the hypothesis that contaminant concentrations in a high-elevation portion of the Sierra Nevada decrease with distance from the adjacent San Joaquin Valley. We sampled air, sediment, and tadpoles twice at 28 water bodies in 14 dispersed areas in Sequoia and Kings Canyon National Parks (2785 – 3375 m elevation; 43 – 82 km from Valley edge). We detected up to 15 chemicals frequently in sediment and tadpoles, including current- and historic-use pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons. Only β-endosulfan was found frequently in air. Concentrations of all chemicals detected were very low, averaging in the parts-per-billion range or less in sediment and tadpoles, and on the order of 10 pg/m3 for β-endosulfan in air. Principal components analysis indicated that chemical compositions were generally similar among sites, suggesting that chemical transport patterns were likewise similar among sites. In contrast, transport processes did not appear to strongly influence concentration differences among sites because variation in concentrations among nearby sites was high relative to sites far from each other. Moreover, a general relationship for concentrations as a function of distance from the valley was not evident across chemical, medium, and time. Nevertheless, concentrations for some chemical/medium/time combinations showed significant negative relationships with metrics for distance from the Valley. However, the magnitude of these distance effects among high-elevation sites was small relative to differences found in other studies between the valley edge and the nearest high-elevation sites.

Concentrations of all chemicals detected were very low, averaging in the parts-per-billion range or less in sediment and tadpoles, and on the order of 10 pg/m3 for beta-endosulfan in air. Principal components analysis indicated that chemical compositions were generally similar among sites, suggesting that chemical transport patterns were likewise similar among sites. In contrast, transport processes did not appear to strongly influence concentration differences among sites, because variation in concentrations among nearby sites was high relative to sites far from each other. Moreover, a general relationship for concentrations as a function of distance from the valley was not evident across chemical, medium, and time. Nevertheless, concentrations for some chemical/medium/time combinations showed significant negative relationships with metrics for distance from the Valley. However, the magnitude of these distance effects among high-elevation sites was small relative to differences found in other studies between the valley edge and the nearest high-elevation sites.

    Holocene climate variability drove important landscape changes in Sierra Nevada, heightened due to the emplacement of Sierra Nevada at 37°N in southwestern Europe and, therefore, the different crossing influences in this region: geographical Europe/Africa), maritime (Atlantic/Mediterranean), climatic (subtropical high-pressure belt/ mid-latitude westerlies). Despite the existence of several kinds of sedimentary records in Sierra Nevada, only two of them can provide further information about Holocene landscape changes in this massif: solifluction lobes and mountain lakes. The numerous sedimentological changes inferred from terrestrial and aquatic records suggest the proximity of geomorphological processes in the massif of their climate boundaries and the small climate range necessary to carry environmental changes in the summits of the Sierra Nevada. Sierra Nevada holds the highest lakes in Europe, all of them related to a glacial origin. Four lakes were cored in Sierra Nevada, three of them southern exposed (Aguas Verdes, Rio Seco and Rio Seco lagoon) and only one with northern orientation (San Juan lagoon). Sedimentological properties of these cores assert evidences of different phases of coarse-grained inputs into the lakes, with low organic matter proportion and high mineral contents. These pulses correspond to geomorphic periods with enhanced slope instability, interfingered in phases with lower sediment transfer onto the lakes. These relative stable periods show a fine-grained texture with less mineral fraction and increases in the organic composition of the sediments. The similar evolution of the C/N ratio and Corg contents reflects the low productivity of these oligotrophic lakes and the terrestrial origin of the organic matter present in their sediments; both proxies also confirm a general pattern characterized in Sierra Nevada by an arid trend since the HWP, when the headwaters of the highest catchments stored a denser vegetation cover. We report an

    Burns remain disproportionately prevalent in developing countries. This study aims to describe the epidemiology of burns in Sierra Leone to serve as a baseline for future programs. A cluster randomized, cross-sectional, countrywide survey was conducted in 2012 in Sierra Leone. With a standardized questionnaire demographics and deaths during the previous 12 months of household members were assessed with the household representative. Thereafter, 2 randomly selected household members were interviewed, elucidating whether participants had ever had a burn in six body regions and determining burn mechanisms and patterns of health care seeking behavior. This study included 1843 households and 3645 individuals. 3.98% (145/3645) of individuals reported at least one burn-injury. The highest proportions of burns were reported in the age groups 0-4 years old (23/426, 5.4%) and 5-14 years old (37/887, 4.17%). The majority of burns (129/145, 89.0%) were caused by a hot liquid/object and the upper, extremities were the most commonly burned body regions, with 36% (53/145) of cases. 21% (30/145) of individuals with burns sought care from a traditional healer. Burns are highly prevalent in Sierra Leone. Further research and resources should be allocated to the care and prevention of thermal injuries. Published by Elsevier Ltd.

    1999-12-01

    Sierra Club values are driven by an overriding environmental ethic. Sierra Club environmental values may be characterized by the concept of 'usufruct' a term favored by United States Founding Father Thomas Jefferson. Usufruct conveys the idea that the environment is ours to use, but not to destroy. Each generation has the obligation to pass on to future generations a world at least as environmentally rich as the one it inherited. It is appropriate to accept risk today in order to preserve the environment for generations yet to come. As viewed through the lens of its formal policies, the Sierra Club is an organization that embraces technology, but insists that technology be evaluated comprehensively, taking full account of both environmental and social externalities. The Club is 'risk averse' with respect to early introduction of technologies seen as likely to have significant negative environmental or social impact. The Club places heavy emphasis on process, which must involve the public meaningfully.

    Full Text Available Abstract Background Malaria is hyper-endemic and a major public health problem in Sierra Leone. To provide malaria treatment closer to the community, Médecins Sans Frontières (MSF launched a community-based project where Community Malaria Volunteers (CMVs tested and treated febrile children and pregnant women for malaria using rapid diagnostic tests (RDTs. RDT-negative patients and severely ill patients were referred to health facilities. This study sought to determine the referral rate and compliance of patients referred by the CMVs. Methods In MSF's operational area in Bo and Pujehun districts, Sierra Leone, a retrospective analysis of referral records was carried out for a period of three months. All referral records from CMVs and referral health structures were reviewed, compared and matched for personal data. The eligible study population included febrile children between three and 59 months and pregnant women in their second or third trimester with fever who were noted as having received a referral advice in the CMV recording form. Results The study results showed a total referral rate of almost 15%. During the study period 36 out of 2,459 (1.5% referred patients completed their referral. There was a significant difference in referral compliance between patients with fever but a negative RDT and patients with signs of severe malaria. Less than 1% (21/2,442 of the RDT-negative patients with fever completed their referral compared to 88.2% (15/17 of the patients with severe malaria (RR = 0.010 95% CI 0.006 - 0.015. Conclusions In this community-based malaria programme, RDT-negative patients with fever were referred to a health structure for further diagnosis and care with a disappointingly low rate of referral completion. This raises concerns whether use of CMVs, with referral as backup in RDT-negative cases, provides adequate care for febrile children and pregnant women.

  16. Is the Isabella anomaly a fossil slab or the foundered lithospheric root of the Sierra Nevada batholith?

    2015-12-01

    The Isabella Anomaly is a volume of relatively high seismic velocity upper mantle beneath the southern Great Valley in California. We deployed ~45 broadband seismometers in central California to test two main hypotheses for the origin of the Isabella Anomaly. One suggests that the Isabella Anomaly is the foundered lithospheric root of the southern Sierra Nevada batholith, which delaminated on account of eclogite-rich composition and translated westward as it began to sink into the asthenosphere. The other hypothesis suggests that the Isabella Anomaly is a fossil slab fragment attached to the Monterey microplate that lies offshore of central California and thus it is mechanically coupled to the Pacific plate. Prior seismic imaging with ~70 km station spacing cannot resolve the landward termination of Monterey microplate lithosphere beneath coastal California or where/if the Isabella Anomaly is attached to North America lithosphere beneath the Great Valley. The new temporary broadband array consists of 40 broadband seismometers with ~7 km spacing extending from the central California coast to the western Sierra Nevada batholith, plus some outliers to fill gaps in the regional network coverage. The temporary array was initially deployed in early 2014 and will continue to record until October 2015 so the complete data are not yet available. Preliminary Ps scattered wave images show an abrupt ~6 km increase in Moho depth eastward across the San Andreas fault, a strong positive impedance contrast that dips westward from ~7-25 km beneath Great Valley, and a sharp Moho with a slight westward dip beneath the western edge of the Sierra Nevada batholith. Apparently low impedance contrast characterizes the Moho beneath the eastern Great Valley and foothills, consistent with near mantle velocities in the lower crust. Processing of the cumulative data that will be available in October 2015 and incorporation of new tomography models into scattered wave imaging are needed before

    The present historiography considers that from the times of Pedro I of Castile, favorable stories to this king must have existed which were destroyed after the triumph of the Trastámara dynasty, only interested in making sure a negative picure of the ";Cruel"; king was shown. In this work we have analyzed possible authors of the chronicles called ";true"; versus Ayala's ";false";, as well as the Relación de la vida del Rey D. Pedro attributed to Gracia Dei. The research allows us to conclude that various characteristics attributed to these characters, as well as the authorship of the chronicles they are adscripted to, are part of an advertising campaign started in the sixteenth century by one branch of the Castilla lineage that looks for the reaffirmation as legitimate descendants of Pedro I.

  20. Challenges to Sierra Nevada forests and their local communities: An observational and modeling perspective

    Science.gov (United States)

    Schmidt, Cynthia L.

    Global forests are experiencing dramatic changes due to changes in climate as well as anthropogenic activities. Increased warming is causing the advancement of some species upslope and northward, while it is also causing widespread mortality due to increased drought conditions. In addition, increasing human population in mountain regions is resulting in elevated risk of human life and property loss due to larger and more severe wildfires. My research focuses on assessing the current vulnerability of forests and their communities in the Sierra Nevada, and how forests are projected to change in the future based on different climate change scenarios. In the first chapter I use Landsat satellite imagery to identify and attribute cause of forest disturbance between 1985 and 2011, primarily focusing on disturbances due to insect, diseases and drought. The change-detection algorithm, Landtrendr, was successfully used to identify forest disturbance, but identifying cause of disturbance was challenging due to the spectral similarities between disturbance types. Landtrendr was most successful in identifying disturbance due to insect, disease and drought in the San Bernardino National Forest, where there is little forest management activity. In the second chapter, I assess whether state or local land use policies in high-fire prone regions exist to reduce the vulnerability of residential developments to wildfire. Three specific land-use tools associated with reducing wildfire vulnerability are identified: (1) buffers around developments; (2) clustered developments; (3) restricting construction on slopes greater than 25%. The study also determines whether demographic and physical characteristics of selected California counties were related to implementing land use policies related to reducing wildfire vulnerability. Results indicate that land use policies related to preventing wildfire-related losses focus on building materials, road access, water availability and vegetation

    Hillhouse, John W.; Gromme, Sherman

    2011-01-01

    We report remanent magnetization measurements from 13 sites in Cretaceous plutonic rocks in the northern Sierra Nevada (38°N–39.5°N). By increasing the number of available paleomagnetic sites, the new data tighten constraints on the displacement history of the Sierra Nevada block and its pre-extensional position relative to interior North America. We collected samples in freshly exposed outcrops along four highway transects. The rocks include diorite, granodiorite, and tonalite with potassium-argon ages (hornblende) ranging from 100 Ma to 83 Ma. By combining our results with previous paleomagnetic determinations from the central and southern Sierra Nevada (excluding sites from the rotated southern tip east of the White Wolf–Kern Canyon fault system), we find a mean paleomagnetic pole of 70.5°N, 188.2°E, A95 = 2.6° (N = 26, Fisher concentration parameter, K = 118). Thermal demagnetization indicates that the characteristic remanence is generally unblocked in a narrow range within 35 °C of the Curie temperature of pure magnetite. Small apparent polar wander during the Cretaceous normal-polarity superchron, plus prolonged acquisition of remanence at the site level, may account for the low dispersion of virtual geomagnetic poles and relatively large K value. Tilt estimates based on overlapping sediments, stream gradients, and thermochronology of the Sierra Nevada plutons vary from 0° to 3° down to the southwest. Without tilt correction, the mean paleomagnetic pole for the Sierra Nevada is essentially coincident with the North American reference pole during the Cretaceous stillstand (125 Ma to 80 Ma). At 95% confidence, the apparent latitude shift is 1.1° ± 3.0° (positive northward), and the apparent rotation is negligible, 0.0° ± 4.7°. Correcting for each degree of tilt, which is limited to 3° on geologic evidence, increases the rotation anomaly 2.2° counterclockwise, while the apparent latitude shift remains unchanged.

    The basement rock of the Pampean flat-slab (Sierras Pampeanas) in the Central Andes was uplifted and rotated in the Cenozoic era. The Western Sierras Pampeanas are characterised by meta-igneous rocks of Grenvillian Mesoproterozoic age and metasedimentary units metamorphosed in the Ordovician period. These rocks, known as the northern Cuyania composite terrane, were derived from Laurentia and accreted toward Western Gondwana during the Early Paleozoic. The Sierra de Umango is the westernmost range of the Western Sierras Pampeanas. This range is bounded by the Devonian sedimentary rocks of the Precordillera on the western side and Tertiary rocks from the Sierra de Maz and Sierra del Espinal on the eastern side and contains igneous and sedimentary rocks outcroppings from the Famatina System on the far eastern side. The Sierra de Umango evolved during a period of polyphase tectonic activity, including an Ordovician collisional event, a Devonian compressional deformation, Late Paleozoic and Mesozoic extensional faulting and sedimentation (Paganzo and Ischigualasto basins) and compressional deformation of the Andean foreland during the Cenozoic. A Nappe System and an important shear zone, La Puntilla-La Falda Shear Zone (PFSZ), characterise the Ordovician collisional event, which was related to the accretion of Cuyania Terrane to the proto-Andean margin of Gondwana. Three continuous deformational phases are recognised for this event: the D1 phase is distinguished by relics of S1 preserved as internal foliation within interkinematic staurolite porphyroblasts and likely represents the progressive metamorphic stage; the D2 phase exhibits P-T conditions close to the metamorphic peak that were recorded in an S2 transposition or a mylonitic foliation and determine the main structure of Umango; and the D3 phase is described as a set of tight to recumbent folds with S3 axial plane foliation, often related to thrust faults, indicating the retrogressive metamorphic stage.

It analyzes his reformist ideas, and explains his work and strategy to defend the Filipino secular clergy, whose rights were being violated by the royal orders of 1848 and 1861. Against the reactionary religious orders, Peláez had a detailed modus operandi to defend the legitimacy of native priests’ control of parishes. Although his activities were cut short by his unexpected death in the earthquake of June 1863, Peláez served as an inspiration to be emulated.

    En este trabajo se intentan aportar algunas claves y datos inéditos sobre la biografía del presbítero criollo filipino Pedro Pablo Peláez, que es, junto con el P. José Burgos, el eclesiástico más destacado de la iglesia de Filipinas del siglo XIX. El trabajo aborda la totalmente desconocida actividad del P. Peláez en el cabildo de la catedral de Manila, donde acabaría siendo con el tiempo su hombre más insigne. Igualmente se analiza el espíritu e ideario reformista de Peláez y sus trabajos y estrategia para defender al clero secular filipino, cuyos derechos estaban siendo vulnerados por una serie de Reales Órdenes (1848 ó 1861 y la actitud reaccionaria de un sector de las órdenes religiosas. Peláez supo articular un modus operandi minucioso y muy efectivo en torno a la legitimidad de los curas filipinos en la dirección de las parroquias del país. Aunque sus actividades cesaron con su inesperada muerte en el terremoto de junio de 1863, Peláez se convirtió en una inspiración y un modelo a seguir.

    Full Text Available [es] Desde la aparición del plano secuencia en forma expresiva con Citizen Kane, tal recurso se convirtió en sinónimo de modernidad cinematográfica. Ni tanto ni tan poco, el uso del plano secuencia, generalmente visible, se lo comprendió como maniera formal y toque de virtuosismo. Con el director portugués Pedro Costa, es posible entender de qué manera la crítica y teoría fílmica sobredimensionan criterios esté-ticos ante lo políticamente correcto. Con la realización de la trilogía sobre Fontainhas, Costa se ha convertido en uno de los directores excéntricos más relevantes de los últimos quince años. El recurrente uso del plano secuencia fílmico y su persuasión política a través de las imágenes discurre sobre las condiciones de producción y recepción del cine contemporáneo, poniendo énfasis en llevar a la luz del día del escenario audiovisual los sectores excluidos de su Lisboa, iniciando un periplo que comienza en Fontainhas. [en] Since the sequence shot expressively appeared with Citizen Kane, this resource became synonymous with cinematic modernity. Neither that much nor that little, the use of the sequence shot, usually visible, is understood as formal manieraand a touch of virtuosity. With the Portuguese director Pedro Costa it is possible to understand how film criticism and theory favor aesthetic criteria rather than what is politically correct. With the production of the trilogy about Fontainhas, Costa has become one of the most important marginal directors in the last fifteen years. The recurrent use of the film sequence shot and his political persuasion through images run on the conditions of production and reception of contemporary cinema, with a clear intention to bring into the light of audiovisual stage the excluded areas of Lisbon, starting a long journey that begins in Fontainhas.

    Full Text Available El artículo analiza cuatro hagiografías, dos de ellas inéditas, que se escribieron en diferentes épocas sobre el Venerable Fr. Pedro de Urraca, que nació en Jadraque, España, en 1583 y murió en Lima, en fama de santidad, en 1657. Se estudia el contenido y objetivo de las obras con el fin de apreciar las diferencias que presentan y las variaciones en el tiempo que, desde la perspectiva de la mentalidad religiosa, reflejan. Pero también se examina la relación que tuvieron con el proceso de beatificación del protagonista, para tratar de entender la influencia que ejercieron en dicho proceso. Al mismo tiempo, se pretende ver la manera como este contribuyó a marcar las características y orientación de las obras. En ese contexto, postulamos que la primera de las hagiografías, la que se escribió un mes después de la muerte del Siervo de Dios y que aún permanece inédita, tuvo una gran influencia en la orientación de la causa de beatificación y hasta cierto punto marcó su trayectoria y también influyó, directa o indirectamente, en las hagiografías que se escribieron con posterioridad.This article analyzes four hagiographies-two of them unpublished-that were written in different periods about the Venerable Friar Pedro de Urraca, who was born in Jadraque, Spain, in 1583, and died in Lima, renowned for his sanctity, in 1657. The author studies the content and objective of these literary works with the purpose of appreciating the differences and the variations over time that they present and reflect, from the perspective of religious mentality.

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

    2012-05-01

    Full Text Available This article analyses the cult salsa song “Pedro Navaja” by Panamanian artist Rubén Blades and the relevance of narrating such a genre peculiar to dancing, an re-writing of “Mack the Knife” – or Die Moritat von Mackie Messer – one which contains, as a sort of mise-en-abyme, elements not only of Kurt Weill’s song, but of both John Gay’s The Beggar’s Opera and Bertolt Brecht’s The Threepenny Opera. This study focuses on the fertile adaptation history of the highwayman Macheath since Gay’s work, on close-readings of “Pedro Navaja” – a narrativized cerebral salsa song – and on the ethics of adapting a character, story or genre. Finally, when the character Pedro Navaja is adapted from Blades’ song by a cineaste and playwright, Blades, furious with what others have done with ‘his’ character, decides to resuscitate his eponymous hero killed off at the end of the original song in order to regain the authority of his creation. From theoretical questions including how to read an adaptation or what constitutes an adaptation, this article focuses on the diachronic recurrences of a specific character-type, on the significance of juxtaposing particular historical junctures and on the violence of adaptation and authorship.

  13. Gothic Fiction Elements in Pedro Almodóvar’s The Skin I Live In (2011

    Directory of Open Access Journals (Sweden)

    Jelena Pataki

    2016-12-01

    Full Text Available The aim of this paper is to explore the elements of Gothic fiction in the critically acclaimed Spanish director Pedro Almodóvar’s 2011 film The Skin I Live In. The film is often viewed as a distinctly modern piece of art in that it dwells on contemporary issues referring to complex ethical and moral dilemmas connected to genetic engineering and the disintegration of an individual’s identity. However, despite the undeniable presence of the said issues, the idea is to show that the film’s structure is in fact solidly built on a much older Gothic fiction matrix featuring many of its well-established, easily discernible motifs and conventions. Starting with the classic Gothic topos – a helpless heroine set in an eerie, claustrophobic architecture, and a grotesque atmosphere evoking a feeling of imminent doom – the paper will consider the film’s portrayal of concepts such as death, doubles, and dreams in order to show that the work of the Spanish director bears many similarities to the canonical Anglophone genre. Inevitably, the analysis will also examine the distinct parallel between Mary Shelley’s seminal Gothic fiction text, Frankenstein, and the contemporary counterparts of its mad scientist and his Creation embodied by Almodóvar’s Dr Robert Ledgard and his Vera.

    Full Text Available This present work aimed to assess the effect of different concentrations of cassava starch, associated or not with prochloraz fungicide, on the postharvest conservation of 'Pedro Sato' guavas. Physiologically mature fruits were immersed in a solution of prochloraz (49.5 g/100 liters of water for 5 min. Fruit treated with distilled water and air dried were used as control. They were immersed in cassava starch suspension at concentrations of 0, 20, 30 and 40 g/L, plus 0.5 mL/L of mineral oil. The fruits were stored at 21.0 ± 1.0 ºC and relative humidity of 85 ± 5%, for 12 days, and were examined at every three days. The combination of prochloraz and cassava starch resulted in delayed loss of firmness and yellowness and inhibited the incidence of lesions caused by Colletotrichum gloeosporioides during the 12 days of storage. Fruits treated with 40 g/L of starch, whether containing prochloraz or not, had unpleasant taste and odor, which suggests the occurrence of fermentation. Control fruits, with and without prochloraz, and those treated with starch with no prochloraz, had nearly 100% lesion occurrence within the 12 days. Starch suspension of 30 g/L, containing prochloraz, was the most effective in maintaining fruit quality.

The treatments evaluated were: 30 days at 10ºC (control; 30 days at 2ºC; one day at 45ºC + 29 days at 2ºC; two days at 45ºC + 28 days at 2ºC; two days at 35ºC + 28 days at 2ºC. After 30 days of storage plus three days at 20ºC, the firmness of the flesh and the titratable acidity were highest in the treatments with thermal conditioning. The incidence of rot was higher in fruits stored for 30 days at 10ºC and those kept for two days at 35ºC, and weight loss was higher in fruits kept for two days at 45ºC. Fruits stored for 30 days at 2ºC and those kept at 45ºC, before storage at 2ºC, did not show substantial alterations in the color of the peel during storage or shelf life, which can be associated with chilling injury.

    2002-01-01

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

    Belitz, Kenneth; Landon, Matthew K.

    2010-01-01

    The Central Eastside study unit is located in California's San Joaquin Valley. The 1,695 square mile study unit includes three groundwater subbasins: Modesto, Turlock, and Merced (California Department of Water Resources, 2003). The primary water-bearing units consist of discontinuous lenses of gravel, sand, silt, and clay, which are derived largely from the Sierra Nevada Mountains to the east. Public-supply wells provide most of the drinking water supply in the Central Eastside. Consequently, the primary aquifer in the Central Eastside study unit is defined as that part of the aquifer corresponding to the perforated interval of wells listed in the California Department of Public Health database. Public-supply wells are typically drilled to depths of 200 to 350 feet, consist of solid casing from the land surface to a depth of about 100 to 200 feet, and they are perforated below the solid casing. Water quality in the shallower and deeper parts of the aquifer system may differ from that in the primary aquifer. The Central Eastside study unit has hot and dry summers and cool, moist, winters. Average annual rainfall ranges from 11 to 15 inches. The Stanislaus, Tuolumne, and Merced Rivers, with headwaters in the Sierra Nevada Mountains, are the primary streams traversing the study unit. Land use in the study unit is approximately 59 percent (%) agricultural, 34% natural (primarily grassland), and 7% urban. The primary crops are almonds, walnuts, peaches, grapes, grain, corn, and alfalfa. The largest urban areas (2003 population in parentheses) are the cities of Modesto (206,872), Turlock (63,467), and Merced (69,512). Municipal water use accounts for about 5% of the total water use in the Central Eastside study unit, with the remainder used for irrigated agriculture. Groundwater accounts for about 75% of the municipal supply, and surface water accounts for about 25%. Recharge to the groundwater flow system is primarily from percolation of irrigation return

    The thermal regime in the extinct Sierra Nevada arc has undergone substantial transformation as a result of the cessation of subduction in the last 30 My. The dynamic mechanism of cooling in the arc has been replaced by re-equilibration of the lithosphere toward continental averages. Preliminary 1D thermal models reveal that the effect of asthenospheric heating at the bottom do not lead to credible changes in the lithospheric temperatures for a 30 My years period in terms of surface manifestations. In the Great Valley, neither the topography nor the surface heat flow show considerable variations before and after the cessation of subduction. On the other hand, Sierra Nevada has experienced substantial uplift in the post subduction California. In the Sierra Nevada, the surface heat flow lags deep temperature response but the topography responds directly to temperatures at depth. As the end of subduction migrated north with the Mendocino triple junction, the dynamic equilibrium between the cold Sierra Nevada and Basin and Range has been upset and the high temperatures of Basin and Range started to invade the Sierra Nevada lithosphere. Our 2D thermal model reveals that conductive heating of the Sierran lithosphere by the hot Basin and Range lithosphere could be the dominant source for the tilted uplift in the Sierra Nevada. The heating from the bottom is likely not very effective in Sierra Nevada as no uplift is observed in the neighboring Great Valley region. The thermal uplift due to Basin and Range heating is substantial at the east edge of the Sierra Nevada and decreases rapidly toward the west. The uplift as far as 100 km toward west could be accommodated by flexural bending of the cold Sierra Nevada lithosphere as the eastern edge thermally expanded. A similar thermo-tectonic scenario could explain the westward tilted Baja-California peninsular ranges which were part of the same tectonic setting of the Sierra Nevada during subduction. We also investigated the

    Full Text Available Over the last thirty-five years, Mexico has maintained a trade liberalization policy which has depressed food production and has reconstructed the structure of the agri-food sector; this has generated a higher food dependence and insecurity. In order to face this structural change, new organizational and socio-productive dynamics have emerged in communities, which take into consideration food diversity, heritage and cultural conditions of rural areas. In this paper, we use the theoretical approach of Localized Agrifood Systems (LAFS and the operative concepts of governance and social innovation to analyze and understand the efforts that at the base of society are created to grant development of productive systems. Therefore, we present the results of an investigation based on the exploration of two LAFS cases; in these cases, different strategies to achieve development have been established: the elaboration of artisanal cheese in the state of Hidalgo, and the production of rice in the state of Morelos, Mexico. Research results show the importance of concepts such as Social Innovation (SI and Governance within the framework of localized agri-food systems in rural studies, this, in order to identify the needs and potentials of family farming and producer’s groups inside the new contexts generated by globalization and market liberation process.

    To assess the relationship between the Tiwanaku polity and the individuals buried at the Middle Horizon (∼AD500-1000) cemetery of Larache in northern Chile, a site that has been singled out as a potential elite foreign enclave. We explore this association through the skeletal remains of 48 individuals interred at the cemetery of Larache using bioarchaeological, biogeochemical, and artifactual evidence. Data from cranial modification practices, violent injury, and the mortuary assemblage are used to explore culturally constructed elements of status and identity, radiogenic strontium isotope analyses provide us with a perspective on the geographic origins of these individuals, and stable carbon and nitrogen analyses allow discussion of paleodiet and access to resources. Radiogenic strontium isotope values show the presence of multiple first generation migrants at Larache. Stable carbon and nitrogen isotope data reveal significant differences among individuals. The mortuary context reveals a standard pattern for the oases but also includes a series of unusual burials with abundant gold and few other objects. Interestingly, both local and nonlocal individuals with different head shapes had access to the differentiated burial context; however nonlocal individuals appear to be the only ones with a heavily maize-based diet. Our evidence shows that Larache served as a burial place for a diverse, yet culturally integrated and potentially elite segment of the Atacameño population, but not a foreign enclave as had been postulated. © 2015 Wiley Periodicals, Inc.

    Full Text Available En este artículo se explica cómo dos grupos indígenas que ha- bitan en dos municipios del sur de Veracruz y hablan diferentes lenguas —nahuas de Mecayapan y zoque-popolucas de Soteapan— construyeron un territorio compartido cuyo eje central fue el uso mancomunado de las tierras a lo largo de varios siglos. También se analizan los efectos que la reforma agraria tuvo en la desestructuración parcial de este territorio, marcando fronteras internas inexistentes hasta entonces. Se muestra, a la vez, cómo dos prácticas culturales —las visitas de los santos y las vela - ciones— han posibilitado la recreación simbólica del antiguo territorio nahua-popoluca pese a haber desaparecido el uso mancomunado de las tierras entre Mecayapan y Soteapan. El análisis se centra en los desfases y tensiones existentes entre, por un lado, las prácticas locales de apropiación del espacio y, por otra parte, las legislaciones y disposiciones administra - tivas del Estado. También se reflexiona sobre el papel que ciertas prácticas culturales —en este caso de origen religioso— tienen en la conformación de territorialidades que recrean territorios ya fragmentados.

  13. Reservoir Considerations and Direct Uses of São Pedro do Sul Hydromineral and Geothermal Field, Northern Portugal

    São Pedro do Sul Hydromineral and Geothermal Field, located in the northern interior zone of Portugal (Lafões zone), has the greatest widespread utilization of geothermal energy in Portugal mainland and is the most important thermal centre from the economical revenues point of view, obtained from direct and indirect utilization of the thermal water, mostly for wellness, health, and leisure of human beings. Recent utilization includes district and greenhouses heating and even cosmetic applications. The Hydromineral Field includes two exploitable zones: the Termas and Vau Poles. The waters are recognised for their mineral and medicinal effects, since the time of the Romans about 2000 years ago and, later on, on the 12th century, by the first King of Portugal, D. Afonso Henriques. The traditional spring and the 500 m well (AC1), located in the Termas Pole, currently supplies artesian hot water flow of about 16.9 L/s with a temperature of 67 °C. Despite the low flow rate of the actual two exploration wells drilled in the Vau Pole, the geothermal potential is high; a new deep well is planned to be drilled in this zone where is expected to obtain fluid temperature of around 75 °C. The occurrence of São Pedro do Sul mineral water, included in the sulphurous type waters, are linked to Hercynian granitoids, emplaced between 290 and 321 Myr. There is a close relationship between the placement of the main hot springs and the Verin-Chaves-Penacova fault, namely Verin (Spain), Chaves, Moledo, and S. Pedro do Sul (Portugal) hot springs. Heat flow generated at shallow crustal zones by the radiogenic host mineral of the granitic rocks, added to the deep Earth heat flow, heats the cold water inflow along fractures. Open fracture network along the main faults allows the hot fluids reach the surface, thus giving chance to the occurrence of hot springs and mineralized cold springs. Coupling between fracture opening and density difference between cold water inflow and hot water

    Full Text Available The studied plutons are close to several batholiths of this region, as Sierra de Mazán and other, but with some mineralogical peculiarities. The magmatic cordierite, common in proximate places, is scarce, as sillimanite, while the andalusite is very rare, with few tourmaline. Fluorite and allanite are also typical accasories only in the granites of the Sierra de Zapata. All plutons are peraluminous of potassic tendency, with cortical affinity.The interpretation of the geochemical values distinguishes between granites of different maturity, emplaced under a predominant influence of active margin for Cerro Negro and Vinquis, while the batholith of Zapata has, below these concepts, a marked feature of within plate.The mineralogical associations suggest that the granites of Cerro Negro and Vinquis were emplaced to pressures of 2 kb or less and temperature of 650º C, while the granites of Zapata had done under conditions of lesser pressure, between 1.5 and 2.0 kb and lower temperature, 600-650º C.A grandes rasgos, los plutones estudiados tienen semejanzas con otros del entorno regional, tal como los de la Sierra de Mazán, pero con peculiaridades mineralógicas. La cordierita magmática, que en lugares próximos es muy abundante, es aquí escasa, al igual que la sillimanita, mientras que la andalucita es muy rara y la turmalina poco frecuente. La fluorita y allanita son accesorios comunes y de cierta abundancia sólo en los granitos de la Sierra de Zapata.Todos los plutones son peralumínicos y de tendencia potásica, con neta afinidad cortical. El estudio estadístico de datos geoquímicos seleccionados, permite diferenciar agrupaciones que tienen un reflejo satisfactorio en los plutones caracterizados, por encima de las variaciones de facies. La interpretación de los valores geoquímicos distingue granitos de desigual madurez, emplazados bajo una influencia predominante de margen activo o intraplaca de características continentales, en

    Two-week average concentrations of ozone (O3), nitric acid vapor (HNO3) and ammonia (NH3) were measured with passive samplers during the 2002 summer season across the central Sierra Nevada Mountains, California, along the San Joaquin River drainage. Elevated concentrations of the pollutants were determined with seasonal means for individual sites ranging between 62 and 88 ppb for O3, 1.0-3.8 microg m(-3) for HNO3, and 2.6-5.2 microg m(-3) for NH3. Calculated O3 exposure indices were very high, reaching SUM00-191 ppm h, SUM60-151 ppm h, and W126-124 ppm h. Calculated nitrogen (N) dry deposition ranged from 1.4 to 15 kg N ha(-1) for maximum values, and 0.4-8 kg N ha(-1) for minimum values; potentially exceeding Critical Loads (CL) for nutritional N. The U.S., California, and European 8 h O3 human health standards were exceeded during 104, 108, and 114 days respectively, indicating high risk to humans from ambient O3.

  16. TAX ELASTICITY IN SIERRA LEONE: A TIME SERIES APPROACH

    Full Text Available The fiscal authorities in Sierra Leone introduced series of reforms in the tax system ranging from continual revisions in tax rate to harmonization and instituting new taxes that are relatively easy to collect. Despite these measures, the output of the tax system as measured by the tax/GDP ratio remains very low averaging 11 per cent contributing to higher fiscal deficits. This study examined the base elasticity of the tax system in Sierra Leone and its major handles using annual data covering the period between 1977and 2009.The Singer method of dummy variables was employed in order to make adjustment for the effect of discretionary tax measures and then compare buoyancy and elasticity measures. The empirical results indicated that buoyancy estimates were higher than elasticity estimates; and that short-run elasticities were lower than the static long-run elasticities. Estimation results further showed that discretionary tax measures were effective in mobilizing additional tax revenues and that the tax system was inelastic during the period.

    Human health depends on reliable access to safe drinking water, but in many developing countries only a limited number of wells and boreholes are available. Many of these water resources are contaminated with biological or chemical pollutants. The goal of this study was to examine water access and quality in urban Bo, Sierra Leone. A health census and community mapping project in one neighborhood in Bo identified the 36 water sources used by the community. A water sample was taken from each water source and tested for a variety of microbiological and physicochemical substances. Only 38.9% of the water sources met World Health Organization (WHO) microbial safety requirements based on fecal coliform levels. Physiochemical analysis indicated that the majority (91.7%) of the water sources met the requirements set by the WHO. In combination, 25% of these water resources met safe drinking water criteria. No variables associated with wells were statistically significant predictors of contamination. This study indicated that fecal contamination is the greatest health risk associated with drinking water. There is a need to raise hygiene awareness and implement inexpensive methods to reduce fecal contamination and improve drinking water safety in Bo, Sierra Leone.

    High resolution tomography of the Sierra Nevada Earthscope Project (Reeg, 2008 & Jones et al., 2012) shows that the core area of the Isabella anomaly (Vp+4-6%) resembles a prolate antiformal slab that plunges steeply SE into the upper mantle to ~200 km depth, extending down from a zone of lower crustal attachment that runs along the southwestern Sierra Nevada and adjacent eastern San Joaquin basin. Receiver function, refraction and tomography also show that areas to the east and south of lower crustal attachment consist of ascended asthenosphere lying directly beneath tectonized Moho. The lower-velocity envelope of the anomaly (Vp+1-4%) extends to 250-300 km depths and covers cross-sectional areas locally in excess of 2x of the higher Vp core. We have leveraged lithospheric structure and geologic history against thermal-mechanical modeling in pursuit of an integrated story for the physical and geologic processes that are governing the development of the anomaly. Initial structure is constrained by mantle xenoliths, differentially exhumed lower crustal exposures, and deep cores in the basin. The initial state further recognizes that: 1. the sub-Sierra Nevada batholith mantle lithosphere, including a substantial thickness (35-40 km) of eclogitic (arclogite) cumulates that were produced during high magma flux arc activity, was cooled to a conductive geotherm by flat slab subduction at the end of the Cretaceous; and 2. the gravitationally metastable mantle lithosphere was thermally mobilized from beneath in the Neogene by the opening of a slab window, which also imposed a state of modest regional extension. We have resolved a class of models that successfully predicts the structure of the anomaly, the timing and kinematics of related lithospheric separation and focused extensional tectonism, the timing and source characteristics of related volcanism, and the spatial/temporal patterns of observed subsidence and uplift transients. A general aspect of most of our model

    Full Text Available Nos proponemos destacar la importancia de José Pedro Varela en el concierto latinoamericano, como constructor del sistema escolar uruguayo. Este trabajo resume largas investigaciones sobre la obra y personalidad de Varela, realizadas años atrás y sintéticamente expresadas en nuestra obra "Varela" (1989. Dicha investigación se basó sustancialmente en la re-lectura de los escritos de aquel y la contextualización de los mismos en el ambiente social, político y económico en que vivió. De ello surgió que la imagen popularizada de Varela ha sido muy esquemática y no rescata lo complejo de su personalidad. En efecto, Varela, joven inteligente y dinámico, inspirado en la obra de Sarmiento, junto con varios jóvenes amigos impulsó la creación de un movimiento educacional (la "Sociedad de Amigos de la Educación Popular" que confluyó en la aprobación -por el Gobierno- de una Ley de Educación y en su designación como Inspector Nacional de Instrucción Pública en 1877. Su temprana muerte en 1879 no le impidió dejar sentada las bases de un sistema escolar, cuyas líneas generales se prolongarían a través de más de un siglo. Si bien no ha sido suficientemente reconocido a nivel internacional, en Uruguay -y en alguna medida, en el Río de la Plata- es una de las figuras destacadas de la historia educacional.
