    Full Text Available El sitio Rincón del Atuel 1 (RA-1 fue uno de los primeros estudiado sistemáticamente en los inicios de la arqueología del sur de Mendoza y del que se conocía solo información proveniente de la superficie. Sobre la base de excavaciones recientes se detallan las evidencias arqueológicas del sitio. Asimismo se incorporan datos disponibles de colecciones previas. Sus ocupaciones se registran en los últimos 1500-1700 años AP y mostrarían dos momentos distintos; el más tardío desde hace unos 1000-1200 años AP y el otro desde esa fecha a unos 1500-1700 años AP. El conjunto más tardío se asocia a un suelo y mostraría características de "sitio somero" mientras que el conjunto inferior se relacionaría depositacionalmente con la planicie de inundación del río Atuel por lo que presentaría mejor resolución temporal. El registro arqueobotánico y los valores isotópicos en muestras humanas avalan una dieta mixta de maíz con otras plantas silvestres al menos para el conjunto más antiguo. La evidencia no es concordante con lo esperable para un patrón semi-sedentario o sedentario propuesto previamente para entender las ocupaciones agrícolas del área. Este registro es significativo para comprender la estructura arqueológica en valles fluviales de zonas áridas, y discutir temas como la intensificación regional y el significado de los cultígenos.Rincón del Atuel-1 is an open air archaeological site located in the current alluvial valley of the Atuel River, Mendoza Province (Argentina. The site was studied during the first stage of archaeological research in southern Mendoza. However, only the surface archaeological record was studied and no information was published about the material in stratigraphic context. Recently, excavations were carried out in order to explore issues related to the Late Holocene human occupation. The results presented here show that the site was occupied from 1500-1700 14C years BP until recently (at least ca

    Substantial populations, such as Mexico City, Auckland, and Portland, are built within or near monogenetic fields, so it is important to understand both eruption precursors and magma plumbing systems in such areas. Directly observing the plumbing systems of this rarely witnessed eruption style provides valuable insight into the nature of magmatic transport and storage within the shallow crust, as well as the associated monogenetic eruptive processes. Within the San Rafael Desert of Central Utah is an exposed Pliocene complex of approximately 2000 mapped dikes, 12 sills, and 60 conduits eroded to a depth of 800 m below the paleosurface. A combination of airborne LiDAR (ALS), provided by NCALM, and terrestrial LiDAR (TLS) surveys are used to map the dip of 5 major sills within a 35 sq km area. The ALS provides a 1 m aerial resolution of exposed volcanic features and the TLS gives vertical measurements to cm accuracy. From these data we determine that the 5-25 m thick sills in this area dip approximately 1 to 6 degrees. Field observations show that steps in sills and related fabrics indicate flow direction in sills during emplacement and that sills normally propagate down dip in the Entrada sandstone host rock away from apparent feeder dikes and conduits. Some sills have foundered roofs, especially near conduits, suggesting that nearly neutrally buoyant magmas emplaced into sills along bed partings in the Entrada, differentiated, and in some cases flowed back into conduits. By volume, at 800 m depth in the San Rafael, nearly all igneous rock (approximately 90 percent) is located in sills rather than in dikes or conduits. These observations are consistent with geochemical models that suggest differentiation in shallow sills explains geochemical trends observed in single monogenetic volcanoes in some active fields. Deformation associated with sill inflation and deflation may be a significant precursor to eruptive activity in monogenetic volcanic fields.

  3. Space Radar Image of San Rafael Glacier, Chile

    1994-01-01

    A NASA radar instrument has been successfully used to measure some of the fastest moving and most inaccessible glaciers in the world -- in Chile's huge, remote Patagonia ice fields -- demonstrating a technique that could produce more accurate predictions of glacial response to climate change and corresponding sea level changes. This image, produced with interferometric measurements made by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) flown on the Space Shuttle last fall, has provided the first detailed measurements of the mass and motion of the San Rafael Glacier. Very few measurements have been made of the Patagonian ice fields, which are the world's largest mid-latitude ice masses and account for more than 60 percent of the Southern Hemisphere's glacial area outside of Antarctica. These features make the area essential for climatologists attempting to understand the response of glaciers on a global scale to changes in climate, but the region's inaccessibility and inhospitable climate have made it nearly impossible for scientists to study its glacial topography, meteorology and changes over time. Currently, topographic data exist for only a few glaciers while no data exist for the vast interior of the ice fields. Velocity has been measured on only five of the more than 100 glaciers, and the data consist of only a few single-point measurements. The interferometry performed by the SIR-C/X-SAR was used to generate both a digital elevation model of the glaciers and a map of their ice motion on a pixel-per-pixel basis at very high resolution for the first time. The data were acquired from nearly the same position in space on October 9, 10 and 11, 1994, at L-band frequency (24-cm wavelength), vertically transmitted and received polarization, as the Space Shuttle Endeavor flew over several Patagonian outlet glaciers of the San Rafael Laguna. The area shown in these two images is 50 kilometers by 30 kilometers (30 miles by 18 miles) in

  7. Public communication on times of environmental crisis. The opening of San Rafael 's uranium complex

    International Nuclear Information System (INIS)

    Full text: Argentina has had a lot of cultural changes in the last few years. An environmental movement has gathered and is trying to stop the opening of the Sierra Pintada uranium complex, near the city of San Rafael, in the south of Mendoza province. Since 2005, several 'groundless information' have been published in the local media about the dangers of this re-opening. These news exaggerate the properties of radon gas, claiming that it will reach San Rafael city (20 miles from the complex), rising radiological risk among the population, etc. This scene shows a 'non-real' picture of the regulatory activities that the Nuclear Regulatory Authority (ARN), a government agency that regulates nuclear facilities in Argentina, is really and systematically accomplishing. In this situation, the board of Directors of ARN decided to entrust a full analysis of the environmental issue in the area. The Office of Press and Communication implemented a local communication plan, using a Strategic and Systemic tool kit. The period to be analyzed is from second semester 2005 to February 2007. A little bit of history: the San Rafael Complex started in September 20 of 1979. It belongs to the National Commission of Atomic Energy (CNEA), a government agency. Until its temporary suspension in 1995 for international market reasons (uranium price was U$S 10 / pound), almost 2 million tons of uranium were processed. Besides its temporary suspension, the ARN has been constantly monitoring this particular former complex. In the year 2001, CNEA notices that the uranium price starts to rise and entrust National Technology University, Avellaneda Branch, to accomplish an Environmental Impact Report, according to the argentine law 25.585. Due especially to the rising of uranium price, (actually, the uranium price is approximately U$S 200) the national government determined to restart the extraction of the mineral again. By the year 2004, with the results of the Environmental Impact report, CNEA

  8. Physical processes of shallow mafic dike emplacement near the San Rafael Swell, Utah

    Science.gov (United States)

    Delaney, P.T.; Gartner, A.E.

    1997-01-01

    Some 200 shonkinite dikes, sills, and breccia bodies on the western Colorado Plateau of south-central Utah were intruded from approximately 3.7 to 4.6 Ma, contemporaneous with mafic volcanism along the nearby plateau margin. Thicknesses of dikes range to about 6 m; the log-normal mean thickness is 85 cm. Despite the excellent exposures of essentially all dikes in strata of the Jurassic San Rafael Group, their number is indeterminate from their outcrop and spacing because they are everywhere greatly segmented. By our grouping of almost 2000 dike segments, most dikes are less than 2 km in outcrop length; the longest is 9 km. Because the San Rafael magmas were primitive and probably ascended directly from the mantle, dike lengths in outcrop are much less than their heights. The present exposures probably lie along the irregular upper peripheries of dikes that lengthen and merge with depth. Orientations of steps on dike contacts record local directions of dike-fracture propagation; about half of the measurements plunge less than 30??, showing that lateral propagation at dike peripheries is as important as the vertical propagation ultimately responsible for ascent. The San Rafael dikes, now exposed after erosion of about 0.5-1.5 km, appear to thicken and shorten upward, probably because near-surface vesiculation enhanced magmatic driving pressures. Propagation likely ceased soon after the first dike segments began to feed nearby sills or vented to initiate small-volume eruptions. Most of the dikes are exposed in clastic strata of the Jurassic San Rafael Group. They probably acquired their strikes, however, while ascending along well-developed joints in massive sandstones of the underlying Glen Canyon Group. Rotation of far-field stresses during the emplacement interval cannot account for disparate strikes of the dikes, which vary through 110??, most lying between north and N25??W. Rather, the two regional horizontal principal stresses were probably nearly equal, and so

  9. Uranium favorability of the San Rafael Swell area, east-central Utah

    International Nuclear Information System (INIS)

    The San Rafael Swell project area in east-central Utah is approximately 3,000 sq mi and includes the San Rafael Swell anticline and the northern part of the Waterpocket Fold monocline at Capitol Reef. Rocks in the area are predominantly sedimentary rocks of Pennsylvanian through Cretaceous age. Important deposits of uranium in the project area are restricted to two formations, the Chinle (Triassic) and Morrison (Jurassic) Formations. A third formation, the White Rim Sandstone (Permian), was also studied because of reported exploration activity. The White Rim Sandstone is considered generally unfavorable on the basis of lithologic characteristics, distance from a possible source of uranium, lack of apparent mineralization, and the scarcity of anomalies on gamma-ray logs or in rock, water, and stream-sediment samples. The lower Chinle from the Moss Back Member down to the base of the formation is favorable because it is a known producer. New areas for exploration are all subsurface. Both Salt Wash and Brushy Basin Members of the Morrison Formation are favorable. The Salt Wash Member is favorable because it is a known producer. The Brushy Basin Member is favorable as a low-grade resource

  10. Permo-triassic volcanism in the San Rafael Block (Mendoza province) and its uraniferous potential

    International Nuclear Information System (INIS)

    This paper describes the Permo-triassic volcanism in the San Rafael Block, Mendoza, Argentina, which forms part of the Choiyoi province and it represents by large volumes of intermediate to silicic ignimbrites with minor sub volcanic bodies of rhyolites, andesites and basandesites. Three different suites can be distinguished: the first one (Lower Section) of Early Permian age, is composed of dacites and rhyolites (SiO2 up to 71 %) with minor andesites, the second one (Upper Section) of Late Permian-Early Triassic age is made up of rhyolites (SiO2 up to 77 %) with some basandesites and andesites, and the third one, of Triassic age is composed of rhyolites (SiO2 > 75 %) and basandecites. These suites are easily distinguished by means of trace element data and are believed to represent the transition between a subduction-related magmatic arc and an extensional tectonic regime. This tectonic setting is similar to the prevalent during the Cenozoic in the Sierra Occidental of Mexico and is favourable for the development of long-lived hydrothermal systems which lead to economic U concentrations (i.e. Sierra de Pena Blanca). In the San Rafael Block, the Dr. Baulies-Los Reyunos U deposit, which is hosted in volcanic sediments, is associated to the first suite (Lower Section). Although minor U concentrations are known, up to date, to be related to the second and third suites, these rocks are fertile and seen to be potential source for the formation of uranium deposits within a volcanic caldera environment.

Los resultados sugieren una distancia muy corta entre las ciudades en las cuales las tasas han aumentado y aquellas en las que han disminuido. La diferencia más significativa es que en Venado Tuerto se encontró una mayor fragilidad en las instituciones públicas, por la falta de articulación entre las mismas. En tanto en San Rafael, los actores entrevistados atribuyen el bajo nivel de conflictividad a una red de prevención de violencias en la cual se coordinan agencias provinciales y municipales. Sin tratarse, ni Venado Tuerto, ni San Rafael, de ciudades violentas en los niveles latinoamericanos más truculentos, ambas muestran resultados diferentes que apuntan directamente a la posibilidad de juntar a las instituciones en un entramado de conversaciones, acuerdos y políticas en conjunto.This article presents the results of a comparative study of two Argentinian cities, namely Venado Tuerto and San Rafael, which revealed different trends in the rates of firearm-related homicides.

En la sección inferior de este ciclo predominan los yacimientos alojados en areniscas de origen epiclástico. En la sección superior, en cambio, se encuentran pequeñas mineralizaciones vetiformes de escasa importancia económica. Durante el emplazamiento y la acumulación de estas volcanitas y sedimentitas pérmicas prevalecieron dos regímenes de esfuerzo diferentes: transpresional (fase orogénica San Rafael y transtensional (etapa postorogénica, los cuales condicionaron los sistemas mineralizantes. Mediante un estudio de fábrica deformacional se evaluó el grado de control ejercido por las estructuras sobre la distribución de las mineralizaciones de uranio durante estas dos etapas de deformación. De esta forma, se intenta aportar nuevos conocimientos sobre la génesis de estos depósitos en la provincia magmática Choiyoi y generar nuevas guías de exploración. A través de este análisis se pudieron definir tres órdenes de magnitud en el control estructural sobre los depósitos asociados al ciclo Choiyoi inferior, cuyo desarrollo fue condicionado por la fábrica de la fase orogénica sanrafaélica.

  17. Rb-Sr ages from La Horqueta formation, San Rafael block, Argentina

    International Nuclear Information System (INIS)

    The San Rafael Block (SRB) lies in west-central Mendoza province, Argentine (35oS-6830'W), and has SSE-NNW structural cenozoic trends in the pre-Andean region. To the North and South it is bounded by the Cuyo and Neuquen oil basins, respectively. To the East the SRB passes into the Pampean plains vanishing under the modern back arc volcanism and sedimentary cover; to the West the boundary is defined by the Frontal Cordillera. The presence of Grenvillian basement rocks (ca. 1100 Ma) in the Sierras Pampeanas Occidentales, and the Cambrian-Ordovician, mainly carbonatic, sedimentary cover of the Precordillera conform a tectonic terrane of 800 km long, which was named as Occidentalia (Dalla Salda et al., 1992), Precordillera Terrane (Astini et al., 1996) or Cuyania (Ramos, 1995). Geotectonic interpretations based on a large amount of geochronological, paleomagnetical, paleobiogeographical and geological evidences stated that both (basement and carbonatic platform) constitute an alochthonous terrane with laurentian affinities, collided on the proto-Andean margin of South America in Upper Ordovician-Silurian (?) times (Ramos, et al., 1998; Astini, 1998; Pankhurst et al., 1998). Paleontological and geological evidences allow interpreting the SRB as a southern extension of the Precordillera (Keller, 1999). On the eastern part of the SRB have been identified a Grenvillian basement and an Ordovician carbonatic sequence at Ponon Trehue (Bordonaro et al., 1996; Cingolani y Varela, 1999; Keller, 1999), and an Ordovician turbiditic deposits at Cerro Bola (Cuerda and Cingolani, 1998). However, the relation with other pre-Carboniferous units of the SRB with Precordillera, e.g. La Horqueta Fm., Rio Seco de los Castanos Fm., El Nihuil doleritic and gabbroic rocks, is controversial due to the scarce geological, paleontological and geochronological data. We present here, as part of a research project on pre- Carboniferous units from SRB, new Rb-Sr geochronological data from La Horqueta

La misma está relacionada a la intrusión de un cuerpo hipabisal de composición riolítica alojado en una sucesión de rocas volcánicas y volcaniclásticas de la sección superior del Grupo Choiyoi. La zona de alteración está representada por sericitización generalizada a la que se sobreimponen brechas y venas silíceas, ocasionalmente con textura drusiforme y con bandas tapizadas por agregados diseminados de pirita y calcopirita subordinada, a las que acompaña escasa arsenopirita. Las brechas y venas silíceas conforman una faja de dirección ONO (azimut 290° - 300° e inclinación vertical, en las que se han reconocido texturas de cuarzo hidrotermal de crecimiento primario, de recristalización y de reemplazo. Entre estas texturas se destacan las crustificaciones complejas, el bandeamiento coloforme y los pseudomorfos de cuarzo según calcita en enrejado, a las que se asocia la presencia de adularia con morfologías sub-rómbica, rómbica y pseudo-acicular. Este conjunto de texturas y morfologías permite establecer que se trata de un sistema epitermal de baja sulfuración con paleozonas de ebullición ascendente.

  9. A LiDAR Survey of an Exposed Magma Plumbing System in the San Rafael Desert, Utah

    Fields of dozens to hundreds of volcanoes are a common occurrence on Earth and are created due to distributed-style volcanism often referred to as "monogenetic." These volcanic fields represent a significant hazard on both local and regional scales. While it is important to understand the physical states of active volcanic fields, it is difficult or impossible to directly observe active magma emplacement. Because of this, observing an exposed magmatic plumbing system may enable further efforts to describe active volcanic fields. The magmatic plumbing system of a Pliocene-aged monogenetic volcanic field is currently exposed as a sill and dike swarm in the San Rafael Desert of Central Utah. Alkali diabase and shonkinitic sills and dikes in this region intruded into Mesozoic sedimentary units of the Colorado Plateau and now make up the most erosion resistant units, forming mesas, ridges, and small peaks associated with sills, dikes, and plug-like bodies respectively. Diez et al. (Lithosphere, 2009) and Kiyosugi et al. (Geology, 2012) provide evidence that each cylindrical plug-like body represents a conduit that once fed one volcano. The approximate original depth of the currently exposed swarm is estimated to be 0.8 km. Volcanic and sedimentary materials may be discriminated at very high resolution with the use of Light Detection and Ranging (LiDAR). LiDAR produces a three dimensional point cloud, where each point has an associated return intensity. High resolution, bare earth digital elevation models (DEMs) can be produced after vegetation is identified and removed from the dataset. The return intensity at each point can enable classification as either sedimentary or volcanic rock. A Terrestrial LiDAR Survey (TLS) has been carried out to map a large hill with at least one volcanic conduit at its core. This survey implements a RIEGL VZ-400 3D Laser Scanner, which successfully maps solid objects in line-of-sight and within 600 meters. The laser used has a near

  13. Effects of flooding and tamarisk removal on habitat for sensitive fish species in the San Rafael River, Utah: implications for fish habitat enhancement and future restoration efforts.

    Tamarisk removal is a widespread restoration practice on rivers in the southwestern USA, but impacts of removal on fish habitat have rarely been investigated. We examined whether tamarisk removal, in combination with a large spring flood, had the potential to improve fish habitat on the San Rafael River in southeastern Utah. We quantified habitat complexity and the distribution of wood accumulation in a tamarisk removal site (treated) and a non-removal site (untreated) in 2010, 1 year prior to a large magnitude and long-duration spring flood. We used aerial imagery to analyze river changes in the treated and untreated sites. Areas of channel movement were significantly larger in the treated site compared to the untreated site, primarily because of geomorphic characteristics of the channel, including higher sinuosity and the presence of an ephemeral tributary. However, results suggest that tamarisk removal on the outside of meander bends, where it grows directly on the channel margins, can promote increased channel movement. Prior to the flood, wood accumulations were concentrated in sections of channel where tamarisk had been removed. Pools, riffles, and backwaters occurred more frequently within 30 m upstream and downstream of wood accumulations compared to areas within 30 m of random points. Pools associated with wood accumulations were also significantly larger and deeper than those associated with random points. These results suggest that the combination of tamarisk removal and wood input can increase the potential for channel movement during spring floods thereby diversifying river habitat and improving conditions for native fish.

    The security is analysed for the transport and storage of radioactive sources and the management of radioactive waste product of practices and interventions in nuclear medicine services in hospitals Calderon Guardia, San Juan de Dios and Mexico. The objective is to assess the compliance with current regulations, the effectiveness and efficiency of the same. The security and compliance with current regulations were considered related to the transport of radioactive sources by the two private companies that provide this service, from the Juan Santamaria airport customs to three hospitals evaluated. Compliance with national and international rules on storage of radioactive sources and waste materials were analyzed. For this has been studied Costa Rican law and the recommendations of international organizations related to the subject matter, in the three nuclear medicine services valued. The national and international background related to radiological accidents occurred with radioactive sources during transport, storage and waste were revised, where highlights that in most cases, these accidents occurred for breach of the regulations established. Studies in Costa Rica on radioactive waste management were analysed, and the current status of nuclear medicine services in terms of radiation safety, which helped with the investigation. The compliance and regulations were analyzed by the result of observation and interviews during development, to finally make a series of findings and provide recommendations that are considered relevant. Various variants and indicators that are defined in the theoretical framework were used; also, the strategy of methodology is described. The purpose of the work has been to provide a scientific nature, and that methodology met the objectives, offering an approach from different angles and the actors involved, and a critical and objective analysis strictly in order to contribute to public health.

    Full Text Available Monnina salicifolia R&P (Polygalaceae se reporta como una de las tres especies más abundantes y representativas en la dispersión de semillas por aves en la zona del Embalse San Rafael La Calera. Es una especie que presenta fenofases reproductivas de forma simultánea y siendo ampliamente consumida por aves, por lo que se le podría atribuir como especie clave en la regeneración de áreas alteradas, y considerada como pionera en los procesos de sucesión. Entre septiembre de 2001 y agosto de 2002, se determinó la estacionalidad de las fases reproductivas, la producción de flores y frutos; y la disponibilidad de frutos maduros de 20 individuos entre 1,5 y 2 m de altura, mediante conteos directos de las estructuras presentes en cada individuo, quincenalmente. Así mismo, se evaluó la dispersión regional de semillas mediante la utilización de perchas artificiales, como última etapa en el ciclo de vida de Monnina salicifolia. Monnina salicifolia presentó floración y fructificación durante todo el año de muestreo y de forma continua. Sin embargo, la mayor producción floral coincidió con la estación seca, mientras que la fructificación aumentó su producción durante la estación de lluvias. Patrón observado generalmente en zonas tropicales y característico de algunas especies pioneras. Aparentemente los factores climáticos que se tuvieron en cuenta en este estudio no actuaron como señales disparadoras en la producción de flores y frutos, quizás debido a la variación poco significativa de estos durante el período de muestreo. Con respecto a la dispersión regional de semillas de Monnina salicifolia, fue constante durante los 12 meses de muestreo, lo cual pudo favorecerse por la fructificación constante de la planta. El mayor número de semillas encontradas bajo las perchas, coincidió con la época seca, época de menor disponibilidad de frutos maduros a escala local, lo cual puede deberse a que la dispersión ocurre a escala

    Rafael Rodriguez is an artist, activist, and Puerto Rican humanist. As an artist, he has explored various media, including drawing, painting, collage, recycled art and sculpture. He won first prize at the Woodstock Art-Rock Fair in 1969, and had exhibitions at the 1964-65 World's Fair in New York. He uses his art to expose fights for social injustice on a political level. In 1987, Rafael was diagnosed as HIV-positive. After a period of depression, he found in education the strength to rise above his fears and take control of his life. He now lives and works in New Jersey at a facility for persons living with AIDS. He became founder of the Red Ribbon Fellowship, and works with countless other organizations. He has recently returned to his art, which was on hold, as a means of conveying to the community his ideas and preoccupations. In 1987 he created five works which comprise his series called Anguish. They express life and death, the sacred and the profane, and the substance and the emptiness. Rafael uses various elements and diverse religious beliefs in a visual and plastic global vision of humanity and the individual. PMID:11362443

  8. Performance evaluation of the activity meters of nuclear medicine services of the hospitals Rafael Angel Calderon, San Juan de Dios and Mexico during the period from July 1, 2008 to December 31, 2008

    International Nuclear Information System (INIS)

    Nuclear medicine has used radioisotopes associated to drugs in order to get them to an organ of interest. The radioisotope has the quality to emit radiation, which passes through the body, after being admitted to it, and this is perceived by equipment such as a gamma camera to study the behavior of the organ under study. The radiation is a energy emission able to boot electrons from atoms and produce ions, thus the chemical composition may be altered, resulting in alterations in the cells. Conditions such as: a onreproductive of the cells, causing a tumor; or alterations in geminal cells, causing genetic alterations, which may occur in the offspring of an individual. For the above reason is that the use of radiopharmaceuticals should be as careful as possible, doing as little radiation exposure, without compromising the quality of the study, these should be applied with more important in more radiosensitive population such as children and older adults. The doses used in nuclear medicine are quantified using a device called activity meters and the proper functioning of the overexposures shall impose or low-quality studies doses outside the range of usefulness. The operation of these machines based on the quality control logs have been studied to discover if there are alterations in dosages of nuclear medicine departments of hospitals Calderon Guardia, San Juan de Dios and Mexico. Tests of zero settings, display, physical monitoring, high voltage, linearity test, stability, background radiation, precision, accuracy and consistency have been performed as quality control. This research is classified as non-experimental longitudinal quantitative. The study population was the record set and the realization of quality control tests made to the hospital activity meters above. The collection of data was performed by two steps, the first taking records concerning quality control of the different hospitals, completed tabulation, gratification and analysis of the same. The

    The San Francisco Bay Area in California and its surroundings are shown in this radar image from the Shuttle Radar Topography Mission (SRTM). On this image, smooth areas, such as the bay, lakes, roads and airport runways appear dark, while areas with buildings and trees appear bright. Downtown San Francisco is at the center and the city of Oakland is at the right across the San Francisco Bay. Some city areas, such as the South of Market district in San Francisco, appear bright due to the alignment of streets and buildings with respect to the incoming radar beam. Three of the bridges spanning the Bay are seen in this image. The Bay Bridge is in the center and extends from the city of San Francisco to Yerba Buena and Treasure Islands, and from there to Oakland. The Golden Gate Bridge is to the left and extends from San Francisco to Sausalito. The Richmond-San Rafael Bridge is in the upper right and extends from San Rafael to Richmond. Angel Island is the large island east of the Golden Gate Bridge, and lies north of the much smaller Alcatraz Island. The Alameda Naval Air Station is seen just below the Bay Bridge at the center of the image. Two major faults bounding the San Francisco-Oakland urban areas are visible on this image. The San Andreas fault, on the San Francisco peninsula, is seen on the left side of the image. The fault trace is the straight feature filled with linear reservoirs, which appear dark. The Hayward fault is the straight feature on the right side of the image between the urban areas and the hillier terrain to the east.This radar image was acquired by just one of SRTM's two antennas and, consequently, does not show topographic data, but only the strength of the radar signal reflected from the ground. This signal, known as radar backscatter, provides insight into the nature of the surface, including its roughness, vegetation cover and urbanization. The overall faint striping pattern in the images is a data processing artifact due to the

    1985-02-01

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

Sin embargo, durante el primer año del gobierno de Rafael Reyes en 1905, fueron instituidos seis nuevos departamentos, para luego, ya en 1908, subdividir el territorio nacional en 34 secciones. El movimiento contrarreformista que siguió a la administración de Reyes en 1909 restableció la división territorial existente antes del Quinquenio, pero ciertas resistencias locales permitieron que algunos de los nuevos departamentos creados recientemente lograran subsistir. El presente artículo constituye una revisión histórica de las transformaciones que sufrió el ordenamiento territorial colombiano durante el gobierno de Reyes, todo con el fin de dar cuenta del papel que cumple el Quinquenio en la definición del mapa político administrativo del país.

    Full Text Available This paper aims to study the implications which shows the phenomenon of noise connected to the violent act in the novel Santo remedio (2006 of Rafael Courtoisie. From a literary perspective, one comes to diverse disciplines as the sociology or the art in search of the links that connect noise and violence in the contemporary society, specially in the postmodernism. Likewise, theoretical as Julia Kristeva or Michel Foucault complete a theoric map that claims of explaining the micropolitics carried out by the protagonist of the work, who ends up by infecting of abject bodies his building. The hypothesis of the paper resides in connecting the violent acts done by Paul Green, protagonist of the novel, with the constant submission of his body and mind to the noise, from every aspect.

    Full Text Available Vibrationism was an art movement developed by the painter Rafael Barradas (1890-1929 between 1917 and 1920, and this period remains one of the most recognized and recognizable of his artistic legacy. The aim of this paper is to look further into the concept of vibrationism in an attempt to reveal which elements of Barradas’ artistic vision he sought to highlight by choosing this particular word. The author begins by addressing the frequent use of the concept of vibration in European avant-garde circles and then focuses on its emergence in Barradas’ works from 1917 onwards. Finally, the meaning given to vibrationism in a text published by Torres- García is analyzed and his artistic interpretation of the style in his own paintings is discussed.El vibracionismo fue el movimiento pictórico practicado por el pintor Rafael Barradas (1890-1929 entre 1917 y 1920, y constituye una de las etapas artísticas más reconocidas y reconocibles de su trayectoría. El objetivo del artículo es el de profundizar en el concepto mismo de “vibracionismo”, para descubrir qué elementos de su propuesta plástica pretendía Barradas poner de relieve al escoger esta palabra en particular. Partiremos del frecuente uso del concepto de vibración en los medios de la vanguardia europea, para centrarnos después en su aparición en relación a la obra barradiana a partir de 1917; finalmente se analiza su significado a partir de un texto publicado por Torres-García, y se estudia su concreción plástica en la obra pictórica del autor.

  17. Pulse on pulse: modulation and signification in Rafael Lozano-Hemmer's Pulse Room

    Directory of Open Access Journals (Sweden)

    Merete Carlson

    2012-06-01

    Full Text Available This article investigates the relation between signifying processes and non-signifying material dynamism in the installation Pulse Room (2006 by Mexican Canadian artist Rafael Lozano-Hemmer. In Pulse Room the sense of pulse is ambiguous. Biorhythms are transmitted from the pulsing energy of the visitor's beating heart to the flashing of a fragile light bulb, thereby transforming each light bulb into a register of individual life. But at the same time the flashing light bulbs together produce a chaotically flickering light environment composed by various layers of repetitive rhythms, a vibrant and pulsating “room”. Hence, the visitor in Pulse Room is invited into a complex scenario that continuously oscillates between various aspects of signification (the light bulbs representing individual lives; the pulse itself as the symbolic “rhythm of life” and instants of pure material processuality (flickering light bulbs; polyrhythmic layers. Taking our point of departure in a discussion of Gilles Deleuze's concepts of modulation and signaletic material in relation to electronic media, we examine how the complex orchestration of pulsation between signification and material modulation produces a multilayered sense of time and space that is central to the sensory experience of Pulse Room as a whole. Pulse Room is, at the very same time, a relational subject–object intimacy and an all-encompassing immersive environment modulating continuously in real space-time.

Este artigo analisa como a ironia, a partir da idéia de “acontecimento” e “cena”, de Linda Hutcheon, seria inerente ao conceito moderno de genealogia, que questiona a crença em uma origem absoluta, no romance A estranha nação de Rafael Mendes, de Moacyr Scliar.

  2. Some contributions of Rafael Lorente de Nó to neuroscience: a reminiscence.

    2002-10-15

    Rafael Lorente de Nó is one of the towering neuroscientists of the 20th century. He was born in Zaragoza, Spain, in 1902. In 1920, he moved to Madrid where he became the youngest, and eventually the best known, of Ramón y Cajal's disciples. In his youth, Lorente de Nó worked with Oskar and Cécile Vogt in Germany and with Robert Bárány in Sweden. In 1934, he moved to the United States, where he first worked at the Central Institute for the Deaf (CID); in 1936, he was invited by Herbert S. Gasser to work at the Rockefeller Institute. After his formal retirement from this institute in 1972, Lorente de Nó spent 5 years at the Head and Neck Surgery Department and Brain Research Institute of the University of California at Los Angeles. He died in Tucson, Arizona, in 1990. Lorente de Nó was a gifted person: a polyglot with a remarkable memory and a versatile intellect, which together with his strong, almost belligerent character, made him a rather controversial human. The strength of his scientific contributions is evident by their current impact. Among these are: the modular (i.e., columnar) organization of the cerebral cortex, the synaptic delay, nerve volume conduction, synaptic summation, and the cybernetic (feed-back) neuron circuit. The present article provides a comment upon some of his neurohistological studies (including the cerebral isocortex, Ammon's horn, brainstem, and spinal cord), highlighted by transcripts from taped conversations with him, and illustrated by reproductions of some of his original figures.

    Full Text Available En los sedimentos que constituyen el relleno de la gruta del Indio, Rincón del Atuel, se reconocieron tres niveles formados por acción fluvial intermitente y cuya distribución horizontal está parcialmente perturbada por la caída de bloques de basalto desde el techo. Los porcentajes y distribución de los componentes orgánicos, constituidos por humus, carbón, fitolitos y colofanita, es muy variable y está regulada por la actividad del hombre y de los animales. Los componentes detríticos son los más abundantes y generalmente superan el 90%, con amplio predominio de los constituyentes livianos. Los litoclastos volcánicos, los vitroclastos y las plagioclasas cálcicas son las variedades más abundantes, acompañadas por escaso cuarzo mono y policristalino, feldespatos potásicos, fragmentos carbonáticos y minerales pesados. De acuerdo a las características de los clastos se puede inferir un aporte sedimentario local, representado por clastos volcánicos provenientes de derrumbes y su mezcla con materiales similares derivados de la erosión de los depósitos subyacentes y otro alóctono fluvial, a los que se suma el aporte piroclástico. El conjunto de sedimentos analizados puede ser incluido en el grupo de las paratufitas. La baja madurez mineralógica de los sedimentos sugiere condiciones climáticas frias y secas. Sin embargo en los niveles superficiales, la presencia de agregados micríticos originados por precipitación in situ de aguas bicarbonatadas, indica condiciones esporádicas de humedad, las que son corroboradas, al igual que las bajas temperaturas, por la presencia de fragmentos quebrados de gutolitas.

  13. SANS studies of polymers

    International Nuclear Information System (INIS)

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H2O/D2O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    San Jose, capital city of Costa Rica, fills the valley between two steep mountain ranges. In this image made from data collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra satellite, visible, shortwave, and near-infrared wavelengths of light that the sensor observed have been combined to produce a false-color version of the scene in which vegetation is red, urban areas are silvery gray, water is dark blue, and clouds are white. The image was captured on February 8, 2007. San Jose is in the center of the image. The Rio Torres winds through downtown San Jose. Cartago, the much smaller colonial capital, sits in the lower right corner, while the city of Alajuela appears across the river, northwest of San Jose. The cities' manmade surfaces contrast sharply with the lushly vegetated landscape surrounding the city. Greenhouses are common in the region, and their glass roofs may be the brilliant white spots around the outer edges the cities. The long, straight runway of the Tobias Bolanos International Airport is visible as a dark line southeast of Alajuela. The landscape around the two cities shown here is rugged. Steep mountain peaks cast dark shadows across their leeward slopes. Patches of dark red vegetation on the mountains north of San Jose may be rainforest. Coffee plantations also cover the slopes of the mountains around the city. February is the dry season in Costa Rica. During the rainy season, from about April to November, clouds usually block the satellite's view of this tropical location.

En este artículo se insiste en la diferencia genérica entre novela utópica y novela de ciencia ficción. A esta última categoría pertenecen las dos novelas de Arévalo. El hecho de que este autor escribiera novelas de ciencia ficción en la Guatemala de los años 30, lo convierte en un pionero de las letras centroamericanas no solo a nivel estético, sino también a nivel ideológico.ABSTRACT: This article examines two novels by Rafael Arévalo Martínez entitled Viaje a Ipanda and El mundo de los maharachías. The aim of it is to shed new light on novels too often disregarded by criticism and show that unlike what is commonly held—that both of them are “utopian novels”—Viaje a Ipanda and El mundo de los maharachías must be understood as science fiction. Arévalo Martínezʼs choice to write science fiction novels in the Guatemala of the 30ʼs makes him a pioneer of Central American literature, not only on an aesthetic level but also on an ideological one.

    The use of prosthesis in reconstruction for the management of extensive tumor bone lesions. The study of six patients treated is performed at the Hospital Rafael Angel Calderon Guardia, who were treated for aggressive tumors in the period 2001-2006. Bony tumors are conceptualized, as well as fundamental aspects of cell biology in its development and the classification of the same. Also, relevant information is included with relation to the most frequent indications and possible treatments. In all six cases was placed the rescue prosthesis, four of them has been obtained excellent results. Limb amputation has been the only alternative until the decade of the 70 and survival rates with this treatment were 10 to 20% survival at 5 years. Today, with advances in chemotherapy and limb salvage prosthesis, patients without metastases at diagnosis have a survival of 65 to 75% at five years. The study has made it possible to simultaneously to analyze some aspects of care to these patients; such as: time of biopsy, time of diagnosis, time of initiation of chemotherapy and surgical intervention time. Through this study has concluded that when referring to a malignant tumor of bone is absolutely essential that the process of diagnosis and initiation of treatment of limb salvage surgery are addressed as soon as possible. Finally, some recommendations are raised to strengthen the treatment of malignant tumors in the Hospital Rafael Angel Calderon Guardia. (author)

The distribution of organic components is quite variable and it is controlled by the human and animal activity. They include: humus, coal, silicophytoliths and collophanite. Detrital grains are the most abundant and represent over 90 % of the whole samples analysed. They are clearly dominated by the light fraction. Volcanic lithoclasts, vitroclasts and calcic plagioclases are the more frequent constituents accompanied by scarce monocrystalline and polycrystalline quartz, potash feldspar, carbonate fragments and heavy minerals. A local sedimentary provenance is suggested on the basis of the clasts features. They are associated with roof's crumbles and the mixture with similar debris resulted from the erosion of the underlying deposits, and aloctonous fluvial and pyroclastic materials. The sediments may be included it the group of the para-tuff and the low mineralogical maturity observed suggests a dry and cold climate. However, micritic aggregates deposited on the surface are considerd to be the result of precipitation in situ of bicarbonated waters which indicates transient humid conditions. This interpretation is constrained for broken dripstones fragments.

Igualmente, el Banco de SemillasPersistente también estuvo dominado por especies anemócoras en 84%. Se estableció la dinámicade estas estrategias en el BSG, a nivel espacial y temporal, teniendo en cuenta la fenofase dedispersión. En la dinámica temporal, se encontró que en general la composición del BSG dependeprincipalmente de la lluvia de semillas y de la persistencia de las mismas. Así en este trabajo, elBanco Transitorio presentó fluctuaciones en su densidad relacionadas con la baja persistencia delas semillas unida a una corta duración de la fenofase de dispersión. Mientras que el BancoPersistente presentó una densidad casi constante, favorecida por la alta longevidad de las semillasy/o una prolongada fenofase de dispersión que permite a las semillas de longevidad moderada,una moderada persistencia, como ocurre en el Banco Pseudopersistente. En cuanto a los tipos dedispersión, su permanencia en el Banco Persistente puede lograrse por una combinación de es-trategias tales como una alta longevidad de las semillas, un ingreso continuo al Banco para el casode la barocoria especialmente, y además un aporte de semillas de origen distante para la zoocoria y la anemocoria. En la dinámica espacial, se encontró que la distribución de las semillas está con-dicionada por un conjunto de factores específicos para cada tipo de dispersión. Así, en la anemocoriadichos factores son de tipo físico como la cobertura de la vegetación, la mayor o menor exposiciónal viento y la altura de la planta parental. En la barocoria, el principal factor parece ser la distanciaentre las plantas parentales y en la zoocoria, la oferta de algún recurso atractivo para los dispersores.The temporary dynamics of each dispersion type was studied (Anemocoria, Zoocoria andBarocoria in the vegetation and in Germinable Seed bank (GSB. The space dynamics of eachdispersion type was also analyzed in the GSB, and the species were identified that the Banks ofTransitory, Persistent type and Pseudopersistente conform, analyzing some Life History traitsthat can be determining such dynamics.

Being a mysterious figure of hislifetime period, Nogales spent almost fifty years of his lifespan outside ofhomeland by going around the world away because of opposition to thedictatorial regimes. Nogales, passionate for military service andadventure, waged war in Cuba in 1898; he worked for dictator PorfirioDiaz as a mounted guard in the Mexican-American border; after a while,he had become a Mexican revolutionist by joining up the rebelliousforces against Diaz; a secret agent in the Far East, an assassin teammember in Guatemala; a rebel for years and a government officialduring the last period of his lifetime in his homeland. Nogales hadexpressed that his motto was; "When you see a good war, join up to it towaged war!" He was considering himself as "a soldier of fortune and thecitizen of the world". He was a military enthusiast, fighter, traveler,adventurer and also a writer. If I may say so, he was the Don Quixote ofthe 20th century.In this study, based on the memoirs quoted in the books ofNogales, his life history has been examined and the narratives of theauthor related the historical events in that period have been researchedcomparatively with the original sources. To this end, various officialsources, records and memoirs have been reviewed and made archivalresearch.

    Full Text Available Introduction: the World Health Organization (WHO recommends that the incidence of cesarean must not exceed 15%; however, its use has increased in the last two decades, which implies a public health problem. Objective: to characterize the maternal and neonatal adverse outcomes of caesarean in the Clínica Maternidad Rafael Calvo (CMRC,Cartagena-Colombia. Methodology: a descriptive cross-sectional study, where after cesarean maternal and neonatal adverse outcomes were characterized. Results: 1.804 cesarean sections (46.5% and 2.073 vaginal deliveries (53.5% were performed. The most common indications for cesarean section were before cesarean (35.5%, cephalo pelvic disproportion (30.6% and oligoamnios (10.8%. The most common adverse maternal outcomes were bleeding requiring transfusion (9.17%, surgical wound hematoma (3.28% and admission to ICU (1.5%.

    Full Text Available Accostumed as we are to the struggles between Spanish Liberal and Conservative traditions, the internal tensions within the reformist field have hardly been attended to. Such is the case with the controversy around the management of intellectual exchanges with Latin America that confronted the University of Oviedo and Rafael Altamira on one side, and the JAE and Canalejas on the other, over the politics of Science promotion taken up by the latter. This articles studies that ideological debate in the 1907-1913 political context, through the analysis of unpublished sources and Altamira's texts on Latin America. The aim is to understand why the shared ideal of international projection of the Spanish science gave way to conflictive strategies

    Acostumbrados a atender a las pujas entre las tradiciones liberales y conservadoras españolas, las tensiones internas del campo reformista han pasado casi desapercibidas. Tal es el caso de la controversia acerca de la gestión del intercambio intelectual con América Latina, que enfrentara a la Universidad de Oviedo y Rafael Altamira, con la política de fomento de la ciencia de Canalejas y la JAE. Proponemos aquí recuperar este debate ideológico en el contexto político de 1907- 1913, analizando fuentes inéditas y textos americanistas de Altamira, para comprender por qué el ideal compartido de la apertura y proyección internacional de la ciencia española, dio lugar a estrategias de acción conflictivas.

En la primera etapa participan fluidos magmáticos de elevada salinidad (37,5-41 % en peso equivalente NaCl y temperatura (356-389°C que dan origen a la alteración potásica y a la mineralización de Cu y en la segunda etapa participan fluidos magmáticos de bajas temperaturas (176-276°C y salinidades (0,35-8,68 % en peso equivalente NaCl los cuales dan lugar a la alteración fílica.The San Pedro porphyry copper deposit, located in the southern part of the San Rafael, Massif, Mendoza province, Argentina, develops an alteration halo in volcanic rocks of the Choiyoi Magmatic Cycle. Close to this alteration halo a group of polymetallic veins that were genetically linked to the disseminated deposit based on stratigraphic data crops out. Fluid inclusions petrographic and microthermometric studies carried on in samples from these veins confirm this genetic link and allow establishing two stages in the evolution of this hydrothermal system. The first stage with high salinity (37.5-41% and temperature (356-389°C magmatic fluids produce potassic alteration and Cu mineralization. During the second stage diluted magmatic fluids with low temperatures (176-276°C and salinities (0.35-8.68% led to phyllic alteration.

  7. Lipid sorting revealed by SANS

    International Nuclear Information System (INIS)

    We have investigated the lipid sorting in a binary small unilamellar vesicle (SUV) composed of cone-shaped (1,2-dihexanoyl-sn-glycero-3-phosphocholine: DHPC) and cylinder-shaped (1,2-dipalmitoyl-sn-glycero-3-phosphocholine: DPPC) lipids. In order to reveal the lipid sorting we adopted a contrast matching technique of small angle neutron scattering (SANS), which extracts the distribution of deuterated lipids in the bilayer quantitatively. The SANS profile of deuterated SUVs at the contrast matching condition showed a characteristic scattering profile, indicating an asymmetric distribution of cone-shaped lipids in the bilayer. The fitting of the observed SANS profile revealed that most DHPC molecules are localized in the outer leaflet, which supports that the shape of the lipid is strongly coupled with the membrane curvature. We compared the obtained asymmetric distribution of the cone-shaped lipids in the bilayer with the theoretical prediction based on the curvature energy model. (author)

  9. Marketing San Juan Basin gas

    International Nuclear Information System (INIS)

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

  10. Structure of microemulsions by SANS

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has been used to determine the structure of microemulsions in the system hydrocarbon-water-sodium di-ethylhexylsulfosuccinate (AOT). SANS spectra taken in a deuterated solvent showed a perfect Guinier fit with a radius of gyration of 15A regardless of the amount of AOT from 0.1 to 5% present. By varying the proportions of deuterated and undeuterated solvent to vary the contrast between the micelles and the solvent, it is concluded that the micelles are basically monodispersed spherical aggregations of 22 AOT molecules

    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.

    Full Text Available Background: pregnancy in adolescence is commonly associated with higher medical risk, psychological problems and social disadvantages. Female adolescents tend to be ignorant on the risks of pregnancy at such age. Objective: to identify the risk perception in pregnant adolescents of the “Rafael Valdés” policlinic. Method: a prospective, descriptive study was conducted at the ‘’Rafael Valdés” policlinic in Cotorro, Habana, from January 1st to December 31st, 2009. It included 79 pregnant adolescents. Variables analyzed: age, educational level, current educational and marital status. Data were collected through direct interview. A questionnaire was also applied in order to assess risk perception in the group of adolescents. Data were processed in Excel, thus determining frequencies and percents. Results: 89, 9 % of adolescents were between 15 and 19 years old, 91, 5 % were single or had unstable partners and 74, 4 % began having sexual relationships after they were 15 years old. 49, 9 % of these adolescents had abandoned their studies. Most of them referred to know about contraception, sexuality and pregnancy risks. They had family support and pregnancy was booked on time. Nevertheless, there was no correspondence with the reasons exposed to continue with pregnancy. Conclusion: the process of orientation and education of adolescents on reproductive health and sexuality issues should be systematic and constitutes our responsibility.Fundamento: el embarazo en la adolescencia se asocia a mayores riesgos médicos, problemas psicológicos y desventajas sociales.

Com esse propósito, vale-se da leitura feita por Ferlosio do ensaio “Destino e Caráter” (1921 de Walter Benjamin. A ambiguidade irônica do narrador de Cercas e a figura do duplo nos seus relatos são vinculados à consciência da heterogeneidade enunciativa e do reconhecimento da complexidade da situação do escritor na atualidade, colocado entre a aceitação das normas da sociedade do espetáculo na literatura e o rechaço das mesmas.

    Geophysical and geospatial data were collected in Buzzards Bay, in the shallow-water areas of Vineyard Sound, and in the nearshore areas off the eastern Elizabeth Islands and northern coast of Martha's Vineyard, Massachusetts, on the U.S. Geological Survey research vessel Rafael between 2007 and 2011, in a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management. This report describes results of this collaborative effort, which include mapping the geology of the inner shelf zone of the Elizabeth Islands and the sand shoals of Vineyard Sound and studying geologic processes that contribute to the evolution of this area. Data collected during these surveys include: bathymetry, acoustic backscatter, seismic-reflection profiles, sound velocity profiles, and navigation. The long-term goals of this project are (1) to provide high-resolution geophysical data that will support research on the influence of sea-level change and sediment supply on coastal evolution and (2) to inventory subtidal marine habitats and their distribution within the coastal zone of Massachusetts.

  1. Velocity selector for SANS spectrometer

    International Nuclear Information System (INIS)

    Mechanical velocity selector, designed firstly at the beginning of the neutron age (the end of 40-th - 50-th, see and references herein) are nowadays of wide use at SANS spectrometers on steady state neutron sources. The present report is devoted to the description of the construction and parameters of the selector, designed for SANS spectrometer at the 1 MW research reactor (URGN, Draria, Algeria). The design of selector provides high transmission (more then 90%) and wavelength resolution of Δλ,/λ ∼ 14%, allowing the neutron wavelength to be selected between 4 A and 10 A. The rotor of selector is an aluminium cylinder rotating in a vacuum jacket around the horizontal axis. The rotor slits of helical shape are formed by absorbing plates with thickness 0.5 mm and made of Gd (10%)-Al alloy. (author)

  2. Sintered materials studied by SANS

    International Nuclear Information System (INIS)

    Complete text of publication follows. The small angle scattering of compacted and sintered single phase materials with open or closed porosity can be described by the two phase model. During sintering, the decrease of pore volume is accompanied with decreasing internal surface measured by SANS [1]. Such investigation can be extended to the field of technically relevant multiphase materials as well, e.g. doped tunsten, SiN ceramics and WC-Co composite made from nano-crystalline powder. The deformation of remaining porosity after sintering can be monitored by 2D anisotropy of SANS distribution as the sintered body is processed through several steps of thermomechanical treatment. The elongation of pores or stable bubbles, e.g. K gas filled bubbles in doped W [2], follows the macroscopic deformation of the body. Heat treatment, however, causes spheroidization with vanishing SANS anisotropy. Our investigation using the isointensity contour map method allows establishing a new description of mechanisms of thermomechanical processing. (author) [1] O. Blaschko, R. Glas, G. Krexner and P.

    San Miguel volcano, also known as Chaparrastique, is a basaltic volcano along the Central American Volcanic Arc (CAVA). Volcanism is induced by the convergence of the Cocos Plate underneath the Caribbean Plate, along a 1200-km arc, extending from Guatemala to Costa Rica and parallel to the Central American Trench. The volcano is located in the eastern part of El Salvador, in proximity to the large communities of San Miguel, San Rafael Oriente, and San Jorge. Approximately 70,000 residents, mostly farmers, live around the crater and the city of San Miguel, the second largest city of El Salvador, ten km from the summit, has a population of ~180,000 inhabitants. The Pan-American and Coastal highways cross the north and south flanks of the volcano.San Miguel volcano has produced modest eruptions, with at least 28 VEI 1-2 events between 1699 and 1967 (datafrom Smithsonian Institution http://www.volcano.si.edu/volcano.cfm?vn=343100). It is characterized by visible milddegassing from a summit vent and fumarole field, and by intermittent lava flows and Strombolian activity. Since the last vigorous fire fountaining of 1976, San Miguel has only experienced small steam explosions and gas emissions, minor ash fall and rock avalanches. On 29 December 2013 the volcano erupted producing an eruption that has been classified as VEI 2. While eruptions tend to be low-VEI, the presence of major routes and the dense population in the surrounding of the volcano increases the risk that weak explosions with gas and/or ash emission may pose. In this study, we present the first inventory of SO2, CO2, HCl, and HF emission rates on San Miguel volcano, and an analysis of the hazard from volcanogenic SO2 discharged before, during, and after the December 2013 eruption. SO2 was chosen as it is amongst the most critical volcanogenic pollutants, which may cause acute and chronicle disease to humans. Data were gathered by the geochemical monitoring network managed by the Ministerio de Medio Ambiente

During the last two decades, critical approaches has shown that the alliance between the past and «the new» is far from being an obstacle that condemns the Spanish «ismos» to be seen as inauthentic ones, and therefore to be accused of not having the transformative impulse that characterized the artistic projects of the early modernized European countries.

    Full Text Available RESUMEN: El caso de Rafael Gasset, propietario y director de "El Imparcial", sirve como modelo ilustrativo del ascenso político y social protagonizado por las élites salidas del periodismo desde fines del siglo XIX. El protagonismo político asumido por Gasset en la crítica coyuntura del 98 sería inexplicable sin tener en cuenta el crédito que le confería su periódico, el diario de más influencia en la España de la Restauración. Todo partido y todo líder político necesitaban en aquellos momentos ejercer algún tipo de control e influencia sobre un gran periódico. Sin él, la jefatura y los partidos no valían nada. Por ello, el periodismo era ya, a fines del siglo XIX, uno de los medios más representativos de ascenso en la política profesional y en el liderazgo social. Las campañas periodísticas de "El imparcial" (Madrid, 1867-1933 fueron, durante décadas, decisivas en la creación de estados de opinión. Estas campañas serían el medio utilizado por Gasset para influir sobre los medios oficiales y para integrarse, de ese modo, en la élite gobernante del régimen de la Restauraciuón. Esta integración se produjo al ser nombrado ministro de Agricultura por Francisco Silvela en abril de 1900. La estrecha vinculación existente desde entonces entre los intereses políticos y periodísticos del nuevo ministro, sin embargo, habría de pagarla muy cara su órgano de información, en términos de pérdida de credibilidad y prestigio entre el público lector independiente.

    Full Text Available Introduction: adolescent pregnancy is considered a problem of public health. The existing care measures do not influence, in a decisive way, in the education of the adolescents, they do not bear in mind neither the familiar niche nor the social niche of poverty that the adolescents have to affront, which lead them to an active sexual life to early age. Where, personal, familiar and social risk factors participate. To overcome them is a matter of educational and economic policies that promote the sexual and reproductive rights of the woman. Objective: to characterize the social factors that are present in pregnant adolescents. Methods: qualitative study of intentional sampling, interviews and focal groups with analysis according to the theory based on pregnant adolescents that attend to the Clínica Maternidad Rafael Calvo, Cartagena, Colombia. Results: personal, familiar and social factors were observed in stories that reveal: “My family did not pay attention to me and I did not fix my limits… I had the support and love of my partner, and although I was not prepared for the pregnancy, it was something that I wanted to go out of my house”. Or in another expression: “I remained a pregnant woman because my friends had sexual relationships and they were telling me… To me, these secrets touched me”. Conclusions: it was observed that pregnant adolescents were in a context lacking in options, which favor decisions in conducts of risk. The state has the obligation and the responsibility of proposing social actions of prevention. Rev.cienc.biomed. 2013;4(2:262-269

El método utilizado es el análisis crítico del discurso de Van Dijk, los actos de habla de Searle y la perspectiva de las metáforas de la vida cotidiana de Lakoff. La hipótesis que orienta la indagación plantea que los primeros pasos de la institucionalización del control escolar estuvieron atravesados por el discurso cristiano-católico expresado en diversos interdiscursos de la época y fundamentalmente en los reglamentos escolares que comenzaron a aparecer como parte de la literatura formativa de los profesores de escuelas primarias. Dicho análisis permite concluir que esta literatura refleja gran parte del imaginario de los profesores de escuelas públicas, ya que expresa un nacionalismobasado en el imaginario de la familia nuclear cristiana, elemento clave que configuró una de las imágenes más vivas en la conformación del estado mexicano posrevolucionario.

  14. SANS from interpenetrating polymer networks

    International Nuclear Information System (INIS)

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

    The use of four beams separated by a cross-shaped aluminum plate inside the collimator tube, placed at the exit of the 40x40 mm{sup 2} guide of the Budapest Neutron Center's small-angle neutron scattering (SANS) spectrometer, allowed us to gain a factor close to 4 in neutron intensity. The aluminum separator and the inner surface of the collimator vacuum tube was coated with boron carbide. The cross-section of each beam was 8x8 mm{sup 2} at the sample position. This setting can be used for measuring large, homogeneous samples, when the measurement does not need high spatial resolution. The beams were focused on the detector by appropriate diaphragms, the collimation length and the sample-detector distance were 4700 mm. In a real SANS experiment we have compared measurements performed on tungsten wire samples with and without beam separator. Using this beam multiplicator the measurement time could be reduced to a quarter.

    San Antonio was selected as an official Mobilizing for Action through Planning and Partnerships (MAPP) demonstration site by National Association of County and City Officials in 2000. The San Antonio Metropolitan Health District, under the leadership of Dr Fernando A. Guerra, agreed to facilitate the process. The MAPP process provided the San Antonio Metropolitan Health District, the local public health authority, a defined process for community health improvement, as well as a mechanism to help bridge the gap between public health and the community. The San Antonio Metropolitan Health District organized a Core Planning Team to lead the MAPP process in April 2001. By October 2002, the Core Planning Team was expanded to a full community working group named the Alliance for Community Health in San Antonio and Bexar County (Alliance). The Alliance identified six strategic issues, which eventually became the basis of the San Antonio Community Health Improvement Plan. The strategic issues are Public Policy, Data Tracking, Healthy Lifestyles, Promoting a Sense of Community, Access to Care, and Safe Environment. San Antonio's MAPP experience has been successful in bringing together the public health system partners, and establishing public health priorities collectively. The MAPP process has resulted in the development of many new initiatives, and, most important, has opened the door to many partnership opportunities in the future. The work of the Alliance, through the MAPP process, has helped to leverage resources for public health improvement in San Antonio, and has the potential to effect positive change in public health in the future.

    International Nuclear Information System (INIS)

    The importance of the use of aspiration biopsy with ultrasonic-guided fine needle is recognized as screening method for diagnosis of thyroid nodules. Thyroid nodules are very common, the prevalence of palpitation has been estimated by 4% and 6% by ultrasound. The prevalence in autopsy data of patients with no history of thyroid pathology has been up to 50%. The use set of advanced imaging techniques and modified techniques of biopsy is implemented in order to increase the diagnostic security of thyroid lesions. The incidental finding of thyroid nodules or incidentalomas has soared dizzily, since the advent of ultrasound as an element in the valuation of thyroid disease and thyroid in the neck. Incidence has been reported even up to 40%. A growing number of endocrinologists are using aspiration biopsy with ultrasound guided fine needle of thyroid nodules as initial diagnostic procedure to identify discrete nodules with a direct location. The percentage of malignant nodules or that require surgery by size or symptomatology, generally, is very low, had to be established a systematic approach to reducing morbidity and mortality associated with major surgery of the neck and reduce costs. The biopsy by fine needle aspiration has been a well established diagnostic technique for preoperative evaluation of thyroid nodules, which has led a significant reduction in the number of unnecessary surgeries in most centers has been between 35-75%. This biopsy has been a specific method, sensitive and inexpensive. The sonographic guidance for biopsy by fine needle aspiration offers the following benefits: is safe and inexpensive, able to reduce costs in 25%, minimally invasive and highly effective, this guidance has increased the detection of malignancy of 14 to 39%. Among the complications that can occur is the formation of hematoma and pain, which are rare. On the other hand, the sonographic guidance is essential for biopsy nonpalpable nodules helping to ensure proper placement of the needle for a more accurate sampling. The nodule with the most striking characteristics or suggestive of malignancy can be biopsied, in patients with multiple nodules, instead of taking the largest size, namely irregular or microlobulated, marked hypoechogenicity, presence of microcalcifications and shape taller high than wide.

    Full Text Available Justificación: La oclusión trombótica de las venas cerebrales o senos durales es una causa menos frecuente de enfermedad cerebrovascular que la trombosis arterial. Sin embargo; los estudios epidemiológicos indican que esta entidad no es tan inusual como o ser pensaba previamente. Hasta donde sabemos, no hay ningún estudio publicando al respecto en la literatura nacional, siendo precisamente el motivo del presente trabajo. Objetivos: Identificar las características demográficas, clínicas y diagnósticas de los pacientes que sufrieron una trombosis de senos venosos durales. Describir los métodos terapéuticos empleados y la evolución que tuvieron estos pacientes. Materiales y métodos: Se revisaron los expedientes clínicos de 11 casos diagnosticados de trombosis de senos durales en el Hospital Dr. Rafael Ángel Calderón Guardia, en el período comprendido entre enero de 1996 a enero de 1999. Se analizaron los posibles factores de riego, formas de presentación clínica, estudios de radio imagen y tratamiento empleado. Resultados: El promedio de edad fue de 32,6 años. Un 18,2% fueron varones, mientras que el 81,8% correspondió a mujeres. Las manifestaciones más frecuentes fueron: cefalea (100%, vómito (91%, déficit motor 882%, alteración del sensorio (73%, papiledema (54,5%, crisis convulsiva (54,5% y datos de irritación meníngea (36,4%: el signo del delta vacío se documentó en 27,3% de los estudios tomográficos. El seno sagital superior fue el más frecuentemente afectado (91%. Se anticoaguló con heparina intravenosa al 54, 5% de los casos. Conclusiones: Aunque somos conscientes de las limitaciones de nuestra serie, nuestra intención ha sido llamar la atención sobre una patología vascular cerebral, que aunque no es tan frecuente como su contraparte arterial, debe tenerse en consideración por sus potenciales efectos sobre la salud del paciente. El conocimiento adecuado de esta condición es importante, debido a que a

    The Trans Bay Cable (TBC) is a ±200-kilovolt (kV), 400 MW 85-km long High Voltage Direct Current (DC) buried transmission line linking Pittsburg, CA with San Francisco, CA (SF) beneath the San Francisco Estuary. The TBC runs parallel to the migratory route of various marine species, including green sturgeon, Chinook salmon, and steelhead trout. In July and August 2014, an extensive series of magnetic field measurements were taken using a pair of submerged Geometrics magnetometers towed behind a survey vessel in four locations in the San Francisco estuary along profiles that cross the cable's path; these included the San Francisco-Oakland Bay Bridge (BB), the Richmond-San Rafael Bridge (RSR), the Benicia-Martinez Bridge (Ben) and an area in San Pablo Bay (SP) in which a bridge is not present. In this paper, we apply basic formulas that ideally describe the magnetic field from a DC cable summed vectorially with the background geomagnetic field (in the absence of other sources that would perturb the ambient field) to derive characteristics of the cable that are otherwise not immediately observable. Magnetic field profiles from measurements taken along 170 survey lines were inspected visually for evidence of a distinct pattern representing the presence of the cable. Many profiles were dominated by field distortions unrelated to the cable caused by bridge structures or other submerged objects, and the cable's contribution to the field was not detectable. BB, with 40 of the survey lines, did not yield usable data for these reasons. The unrelated anomalies could be up to 100 times greater than those from the cable. In total, discernible magnetic field profiles measured from 76 survey lines were regressed against the equations, representing eight days of measurement. The modeled field anomalies due to the cable (the difference between the maximum and minimum field along the survey line at the cable crossing) were virtually identical to the measured values. The modeling

    Small-angle neutron scattering (SANS) has proved to be an excellent technique for the study of complex fluids. This article introduces SANS from the viewpoint of such studies. The use of SANS to determine the structures of concentrated micellar fluids is then discussed within the framework of current one-component macrofluid (OCM) models, and experimental examples are taken from several contemporary studies. Finally, the discussion is extended to magnetic fluids (ferrofluids) in which the neutron magnetic interaction plays an important experimental role. 25 refs., 11 figs., 1 tab.

    The creation and use of a vertically integrated data base, including LANDSAT data, for local planning purposes in a portion of San Bernardino County, California are described. The project illustrates that a vertically integrated approach can benefit local users, can be used to identify and rectify discrepancies in various data sources, and that the LANDSAT component can be effectively used to identify change, perform initial capability/suitability modeling, update existing data, and refine existing data in a geographic information system. Local analyses were developed which produced data of value to planners in the San Bernardino County Planning Department and the San Bernardino National Forest staff.

It has been describedthat colonization of pregnant women by the bacteria Streptococcus agalactiae entailsunfavorable effects about the maternal and neonatal health.Objective: to determine the frequency of vaginal and rectal colonization by Streptococcusagalactiae and its susceptibility to antibiotics in pregnant women with preterm labor.Methods: with prior informed consent, vaginal and rectal specimens were taken to pregnantwomen with preterm labor who admitted to the Clínica Maternidad Rafael Calvo, Cartagena,Colombia, between August 1st, 2011 and January 31st, 2012. The isolations of S.agalactiae were gotten by means of culture in selective medium CHROMagar™ StrepB. Theconfirmation of the specie was carried out by means of CRP with specific primers. Proofsof antibiotic susceptibility were done with Kirby-Bauer methods. Additionally, a form wasapplied to register socio-demographic data and medical record. As an independent variablewas used the colonization, which was correlated with socio-demographic and obstetric dataand with prenatal results. Telephonic follow-up was done for one month.Results: 93 patients were included in the study. A prevalence of 37.6% for vaginal andrectal colonization by Streptococcus agalactiae was found. 15 (16.1% newborns presentedneonatal sepsis. There were not found statistically significant differences in the perinatalresults between the colonized and not colonized groups. There were found statistically significantdifferences in the gestational age between early preterm and late preterm births.Conclusions: Although the occurrence of neonatal sepsis was associated with being earlypremature, there was not association with the colonization status by Streptococcus agalactiaein the mother.

    SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

    Morón Serna, E.

    2015-03-01

    Full Text Available The recovery of the districts built during the second half of the twentieth century, especially those with greater social difficulties, constitutes a sustainable alternative to the failure of continuous urban growth. It is essential to promote integral actions in order to correct both deficiencies and deterioration in residential buildings, improve the relationship of these areas with their urban environments, provide them with facilities and high quality public spaces, as well as to encourage local civil community involvement. On the basis of the experiences and tools that have been developed over the past decade in Andalusia, this paper analyzes the integral renovation of the so called San Martin de Porres district. Here we study its urban and architectural development –standing out the work of the architect Rafael de La-Hoz– as well as the social transformations of its population. From the study of the design, management and execution of its renovation the most relevant aspects are deduced with the objective of facilitating their consideration in future renovation policies.La recuperación de barriadas construidas en la segunda mitad del siglo XX, especialmente aquellas con mayores dificultades sociales, constituye una alternativa sostenible al fracaso del continuo crecimiento urbano. Es necesario promover actuaciones integrales que corrijan el deterioro y carencias de edificios residenciales, mejoren las relaciones de estos ámbitos con sus entornos urbanos, los doten de equipamientos y espacios públicos de calidad e impulsen la participación vecinal y su desarrollo social y económico. A partir de experiencias e instrumentos desarrollados en la última década en Andalucía, se analiza la rehabilitación integral de la barriada de San Martín de Porres en Córdoba. Se aborda su desarrollo urbanístico y arquitectónico –donde sobresale la figura de Rafael de La-Hoz– y las transformaciones sociales de su población. Del dise

  4. Chronology of eclipse "San Miao"

    2001-06-01

    The ancient book "Mozi" (5th century BC) records: "In ancient times, the San Miao tribes were in disarray. The sun rose in the evening...King Yu vanquished them. "King Yu is a prehistoric person living in 23-19th century BC. The strange phenomena "sun rose in evening" was explained as a large solar eclipse at sunset by Pang. Therefore investigations on it may lead to an important progress of Chinese chronology. After an analysis on all similar records in Chinese history, we pay main attention to the relationship of eclipse computations with parameter "c", the long term of earth's rotation rate. We have computed all the solar eclipses in that period by the way similar to that used for investigating the "double dawn" eclipse. By change parameter "c" in reasonable range (28-36 sec/cy2), we have found 11 possible results listed in a table. One figure shows the eclipse maps and relative "double dawn/dusk" areas while another one illustrates how the parameter "c" affects the result. For an exact conclusion of King Yu's chronology, we need further progress from both side: history which may limit the King Yu's period and astronomy which may limit the possible range of parameter "c".

    2012-04-01

    Full Text Available This article contributes to the history of Cuban and Colombian literary criticism at the end of the 19[th] century. It analyzes Rafael María Merchán's Estudios críticos (1886, written and published during the author's exile in Colombia, and suggests that this kind of transnational Cuban-Colombian-Spanish American corpus is positioned within, and is the result of, the negotiations between coloniality and post-coloniality in the late 19[th] century. Its findings show that the important critical legacy of Merchan - trapped between the tangles of Cuba's colonial situation and a post-colonial, post-independent Colombia - constitutes an unclaimed inheritance in the history of Spanish American (and especially Cuban and Colombian literature.

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

    Science.gov (United States)

    Hudnut, K. W.

    2013-12-01

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

  16. Compact High Resolution SANS using very cold neutrons (VCN-SANS)

    International Nuclear Information System (INIS)

    SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

His other facets, as a historian of education, as a researcher of scientific methodology and didactics of teaching and as a pioneer in studies of historic historiography, pale beside the strength of his contributions as successful author of school handbooks of history and geography.Sin lugar a dudas, la faceta profesional e intelectual más destacada de las distintas actividades desarrolladas por el catedrático de bachillerato Rafael Ballester, a lo largo de los tres primeros decenios del siglo XX, es la de ser autor de manuales escolares, algunos de ellos con un éxito ampliamente reconocido. Su figura es una clara muestra de las preocupaciones, empeños y desvelos de la Institución Libre de Enseñanza por la mejora de la enseñanza de la historia y de la geografía en España. Sus otras facetas, como historiador de la educación, como investigador de la metodología científica y didáctica de la geografía y como pionero en los estudios de la historiografía histórica, quedan un tanto empalidecidas frente a la pujanza de sus aportaciones como autor de manuales escolares de historia y de geografía.

  19. Cacao use and the San Lorenzo Olmec

    OpenAIRE

    Powis, Terry G.; Cyphers, Ann; Gaikwad, Nilesh W.; Grivetti, Louis; Cheong, Kong

    2011-01-01

    Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, an...

  17. A case for historic joint rupture of the San Andreas and San Jacinto faults

    Science.gov (United States)

    Lozos, Julian C.

    2016-01-01

    The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior. PMID:27034977

    2005-11-01

    Currently the mainstream technology of SAN is SAN storage virtualization and its implementation. The switch-based storage virtualization embeds the virtualizer in the core of the storage networking fabric in an "intelligent switch" rather than an appliance or a host. This paper describes the SV-FC SAN switch's hardware and software architecture. The main aid of design and implementation the switch is to give a new way to realize FC-SAN storage virtualization. Storage virtualization modules are embedded in the switches firmware. The switch can provide simple and friendly interfaces for users to configure and manage the FC SAN.

    The San Cristobal Galapagos wind power project was described. With its unique endemic flora and fauna, the Galapagos Islands were declared a world heritage site and marine reserve. The San Cristobal wind project was initiated in 1999 to reduce the environmental impacts of energy use on the island, and has been operational since 2007. Three 800 kW wind turbines have been installed in order to reduce 52 per cent of the island's diesel generation. The project's high penetration wind-diesel hybrid system included 300 kW diesel generators, a 13.2 kV utility distribution system, and six 300 kW wind turbines. The project is located outside of Galapagos Petrel flight paths and nesting areas. Turbines from a factory in Spain were used. The wind turbine foundation was constructed from concrete sand and stone mined on the island. Photographs of the installation process were included. tabs., figs.

  20. SANS Measurement of Hydrides in Uranium

    International Nuclear Information System (INIS)

    SANS scattering is shown to be an effective method for detecting the presence of hydrogen precipitates in uranium. High purity polycrystalline samples of depleted uranium were given several hydriding treatments which included extended exposures to hydrogen gas at two different pressures at 630 C as well as a furnace anneal at 850 C followed by slow cooling in the near absence hydrogen gas. All samples exhibited neutron scattering that was in proportion to the expected levels of hydrogen content. While the scattering signal was strong, the shape of the scattering curve indicated that the scattering objects were large sized objects. Only by use of a very high angular resolution SANS technique was it possible to make estimates of the major diameter of the scattering objects. This analysis permits an estimate of the volume fraction and means size of the hydride precipitates in uranium

    An updated summary of a future large astrometric catalogue is presented, based on the two most important astrometric projects carried out by the Real Instituto y Observatorio de la Armada de San Fernando (ROA). The goal is to make a catalogue of positions and proper motions based on ROA's Cart du Ciel (CdC) and the Astrographic Catalogue (AC) San Fernando zone plates, and the HAMC2 meridian circle catalogue. The CdC and AC plates are being reduced together to provide first-epoch positions while HAMC2 will provide second-epoch ones. New techniques have been applied, that range from using a commercial flatbed scanner to the proper reduction schemes to avoid systematics from it. Only thirty plates (out of 540) remain to be processed, due to scanning problems that are being solved.

    International Nuclear Information System (INIS)

    The instrument SANS-1 at the Geesthacht neutron facility GeNF was used for scattering experiments in 2000 at 196 of 200 days of reactor and cold source operation. The utilisation was shared between the in-house R and D program and user groups from different universities and research centers. These measurements were performed and analysed either by guest scientists or GKSS staff. The focus of the work in 2000 at the experiment SANS-1 was the structural investigation of hydrogen containing substances such as biological macromolecules (ribosomes, protein-RNA-complexes, protein solutions, glycolipids and membranes), molecules which are important in the fields of environmental research (refractoric organic substances) and technical chemistry (surfactants, micelles).

  5. Anisotropy of SANS in metallic glasses

    International Nuclear Information System (INIS)

    SANS in metallic glasses is anisotropic and depends on the ribbon's orientation. Pd-based melt spun and Ni-based electrochemically deposited glasses exhibit different anisotropies. Both glasses contain scattering centers of the order of 40nm wide in the ribbon plane. In the melt-spun alloy, the scatterers are very thin along the thickness perpendicular to the substrate. In the deposited alloy however, the defects are long along the thickness perpendicular to the electrode

    2006-03-27

    Salt management has been a challenge to westside farmerssince the rapid expansion of irrigated agriculture in the 1900 s. Thesoils in this area are naturally salt-affected having formed from marinesedimentary rocks rich in sea salts rendering the shallow groundwater,and drainage return flows discharging into the lower reaches of the SanJoaquin River, saline. Salinity problems are affected by the importedwater supply from Delta where the Sacramento and San Joaquin Riverscombine. Water quality objectives on salinity and boron have been inplace for decades to protect beneficial uses of the river. However it wasthe selenium-induced avian toxicity that occurred in the evaporationponds of Kesterson Reservoir (the terminal reservoir of a planned but notcompleted San Joaquin Basin Master Drain) that changed public attitudesabout agricultural drainage and initiated a steady stream ofenvironmental legislation directed at reducing non-point source pollutionof the River. Annual and monthly selenium load restrictions and salinityand boron Total Maximum Daily Loads (TMDLs) are the most recent of thesepolicy initiatives. Failure by both State and Federal water agencies toconstruct a Master Drain facility serving mostly west-side irrigatedagriculture has constrained these agencies to consider only In-Valleysolutions to ongoing drainage problems. For the Westlands subarea, whichhas no surface irrigation drainage outlet to the San Joaquin River,innovative drainage reuse systems such as the Integrated Farm DrainageManagement (IFDM) offer short- to medium-term solutions while morepermanent remedies to salt disposal are being investigated. Real-timesalinity management, which requires improved coordination of east-sidereservoir releases and west-side drainage, offers some relief toGrasslands Basin farmers and wetland managers - allowing greater salinityloading to the River than under a strict TMDL. However, currentregulation drives a policy that results in a moratorium on all

  7. High frequency radar measurements of tidal currents flowing through San Pablo Strait, San Francisco Bay

    Science.gov (United States)

    Maresca, Joseph W., Jr.; Padden, Robin R.; Cheng, Ralph T.; Seibel, Erwin

    1980-01-01

    High frequency (HF) radar measurements of the surface current averaged over the upper 0.5 m in San Pablo Strait were compared with current meter measurements of the subsurface current made at 9.4 m below mean lower low water (MLLW) over two 12.4-h tidal cycles. After averaging the radar and current meter data over two tidal cycles, a southerly (ebbing direction) surface current of 32 cm·s−1 was deduced from the radar measurements and a northerly (flooding direction) subsurface current of 7 cm·s−1 from the current meter measurements. This nontidal flow is maintained by freshwater discharge from the Sacramento–San Joaquin Rivers into Suisun and San Pablo Bays. The radar measurement technique provides quantitative estimates of the surface currents that previously were determined only from surface drifter studies.

  8. Space Radar Image of San Francisco, California

    Science.gov (United States)

    1994-01-01

    This is a radar image of San Francisco, California, taken on October 3,1994. The image is about 40 kilometers by 55 kilometers (25 miles by 34 miles) with north toward the upper right. Downtown San Francisco is visible in the center of the image with the city of Oakland east (to the right) across San Francisco Bay. Also visible in the image is the Golden Gate Bridge (left center) and the Bay Bridge connecting San Francisco and Oakland. North of the Bay Bridge is Treasure Island. Alcatraz Island appears as a small dot northwest of Treasure Island. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on orbit 56. The image is centered at 37 degrees north latitude, 122degrees west longitude. This single-frequency SIR-C image was obtained by the L-band (24 cm) radar channel, horizontally transmitted and received. Portions of the Pacific Ocean visible in this image appear very dark as do other smooth surfaces such as airport runways. Suburban areas, with the low-density housing and tree-lined streets that are typical of San Francisco, appear as lighter gray. Areas with high-rise buildings, such as those seen in the downtown areas, appear in very bright white, showing a higher density of housing and streets which run parallel to the radar flight track. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: the L-band (24 cm), C-band (6 cm) and X-band (3cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes

  9. Development of 40m SANS and Its Utilization Techniques

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

    This paper reviewed two types of network storage technique: NAS and SAN. After comparing and ana-lyzing, it concluded that the ultimate realization of network storage will be in the eventual convergence of NAS andSAN architectures. Currently, all the integration methods are based on the architecture level. This paper present-ed a device-level integration scheme based on IXP1200 network processor. The device can be used as an NAS fileserver or an SAN's storage node. Furthermore, it can be used as a bridge to connect NAS and SAN, and then beshared by their clients.

  1. Study of silica sorbents by SANS

    International Nuclear Information System (INIS)

    Silica gels under study are materials intended for use as the packing sorbents in liquid chromatography (LC), namely in gel permeation chromatography (GPC). The quality of silica for LC should meet strict physical and chemical parameters. Especially in GPC is very important to know pore size and pore shape because they control the whole process of chromatographic separation. Pore size and thickness of pore wall can be measured by various methods. SANS technique is a nondestructive method providing an average information about a large number of scattering object in our case about objects (pore or wall) in silica and their shape. (author)

    Full Text Available La historia de las elites decimonónicas ha sido contada como la historia de un Olimpo tan elevado e inalcanzable como serio. Juan Rafael Allende logró en el mismo siglo XIX crear un mundo paralelo si no alternativo que derribó tanta sospechosa sublimidad. El gran autor satírico se hizo cargo del habla histórica de la plebe chilena que provenía en alguna medida de la Picaresca española de los siglos XVI y XVII con su anticlericalismo y su anticapitalismo visceral y carnavalesco. Prolongando este mundo al siglo XIX Allende lo convirtió en una dinamita contra la gravedad del Estado y del Mercado `en forma'. En particular, fueron atacados insignes representantes de la burguesía chilena como Eduardo Matte, Manuel José Irarrázaval, Agustín Edwards, Julio Zegers o Federico Varela. Ellos habían creado una nueva religión del dinero que Allende se apresuró a denunciar como una burda parodia del Dios cristiano. Había nacido en el país un nuevo credo, el "credo de los salitreros". El origen del pensamiento satírico de Allende tiene larguísimas raíces de las que no podemos obviar, además de la mencionada Picaresca, la tradición de la España hispano-árabe, que se rió de ricos y magnates en el mejor espíritu del Libro del Buen Amor y sus antecedentes musulmanesThe history of Chile's 19th-century elites has been narrated as an Olympian story: lofty, unreachable and grave. During the same century, writer Juan Rafael Allende managed to create a parallel, if not alternative world which demolished such suspect sublimity. The great satiric author appropriated Chile´s historic plebeian speech, somehow descended from the Spanish picaresque of the 16th and 17th centuries, adopting its visceral and carnival-like anti-clericalism and anti-capitalism. Projecting this mode into the 19th century, Allende turned it into a weapon to be used against the gravitas of the formal Market and State. In particular, his attacks were leveled against renowned

  6. The radiological accident in San Salvador

    International Nuclear Information System (INIS)

    On 5 February 1989, a radiological accident occurred at an industrial irradiation facility near San Salvador, the capital of the Republic of El Salvador. Prepackaged medical products are sterilized at the facility by irradiation by means of an intensely radioactive cobalt-60 source in a movable source rack. The accident happened when this source rack became stuck in the irradiation position. The operator bypassed the irradiator's already degraded safety systems and entered the radiation room with two other workers to free the source rack manually. The three workers were exposed to high radiation doses and developed the acute radiation syndrome. Their initial hospital treatment in San Salvador and subsequent more specialized treatment in Mexico City were effective in countering the acute effects. However, the legs and feet of two of the three men were so seriously injured that amputation was required. The worker who had been most exposed died six and a half months after the accident, his death being attributed to residual lung damage due to irradiation, exacerbated by injury sustained during treatment. The report details the events leading up to the accident, the circumstances of the accident itself and the response to it. From the facts established, lessons are derived for operators and suppliers of irradiators, national authorities, medical staff and international organizations. Detailed information on dosimetric and medical aspects of the accident for the specialist reader is presented in the appendices and annexes. 20 figs, 9 tabs, 24 photographs

  7. Synthetic seismicity for the San Andreas fault

    Directory of Open Access Journals (Sweden)

    S. N. Ward

    1994-06-01

    Full Text Available Because historical catalogs generally span only a few repetition intervals of major earthquakes, they do not provide much constraint on how regularly earthquakes recur. In order to obtain better recurrence statistics and long-term probability estimates for events M ? 6 on the San Andreas fault, we apply a seismicity model to this fault. The model is based on the concept of fault segmentation and the physics of static dislocations which allow for stress transfer between segments. Constraints are provided by geological and seismological observations of segment lengths, characteristic magnitudes and long-term slip rates. Segment parameters slightly modified from the Working Group on California Earthquake Probabilities allow us to reproduce observed seismicity over four orders of magnitude. The model yields quite irregular earthquake recurrence patterns. Only the largest events (M ? 7.5 are quasi-periodic; small events cluster. Both the average recurrence time and the aperiodicity are also a function of position along the fault. The model results are consistent with paleoseismic data for the San Andreas fault as well as a global set of historical and paleoseismic recurrence data. Thus irregular earthquake recurrence resulting from segment interaction is consistent with a large range of observations.

Los genesanómalos de la hemoglobina se originaron en África, Asia y la cuenca mediterránea, y debido a las migraciones de este grupopoblacional se han esparcido en todo el mundo, especialmente en América Latina. En esta zona geográfica, a la que pertenece elCaribe colombiano, es notorio el predominio de la anemia de células falciformes o drepanocitosis. Este tipo de anemia se caracterizapor la presencia de hematíes en forma de hoz como consecuencia de la presencia de hemoglobina S, con manifestaciones clínicascomo anemia hemolítica y fenómenos vasooclusivos. La alteración en la estructura y función de la hemoglobina causa deficiencias enel transporte de oxígeno por parte de los eritrocitos, con el consiguiente daño tisular con lesiones infartantes que se reflejan enincapacidad parcial o total e incluso en la muerte. La prevención de las complicaciones debidas a las hemoglobinopatías se basa en laidentificación de los individuos en riesgo a través de sus antecedentes familiares o mediante programas de detección de losportadores, y en proveer la información adecuada sobre los riesgos y las posibilidades de minimizarlos.

    The San Joaquin - Tulare Conjunctive Use Model (SANTUCM) was originally developed for the San Joaquin Valley Drainage Program to evaluate possible scenarios for long-term management of drainage and drainage - related problems in the western San Joaquin Valley of California. A unique aspect of this model is its coupling of a surface water delivery and reservoir operations model with a regional groundwater model. The model also performs salinity balances along the tributaries and along the main stem of the San Joaquin River to allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. This document is a detailed description of the various subroutines, variables and parameters used in the model.

  16. Microbial biogeography of San Francisco Bay sediments

    Lee, J. A.; Francis, C. A.

    2014-12-01

    The largest estuary on the west coast of North America, San Francisco Bay is an ecosystem of enormous biodiversity, and also enormous human impact. The benthos has experienced dredging, occupation by invasive species, and over a century of sediment input as a result of hydraulic mining. Although the Bay's great cultural and ecological importance has inspired numerous surveys of the benthic macrofauna, to date there has been almost no investigation of the microbial communities on the Bay floor. An understanding of those microbial communities would contribute significantly to our understanding of both the biogeochemical processes (which are driven by the microbiota) and the physical processes (which contribute to microbial distributions) in the Bay. Here, we present the first broad survey of bacterial and archaeal taxa in the sediments of the San Francisco Bay. We conducted 16S rRNA community sequencing of bacteria and archaea in sediment samples taken bimonthly for one year, from five sites spanning the salinity gradient between Suisun and Central Bay, in order to capture the effect of both spatial and temporal environmental variation on microbial diversity. From the same samples we also conducted deep sequencing of a nitrogen-cycling functional gene, nirS, allowing an assessment of evolutionary diversity at a much finer taxonomic scale within an important and widespread functional group of bacteria. We paired these sequencing projects with extensive geochemical metadata as well as information about macrofaunal distribution. Our data reveal a diversity of distinct biogeographical patterns among different taxa: clades ubiquitous across sites; clades that respond to measurable environmental drivers; and clades that show geographical site-specificity. These community datasets allow us to test the hypothesis that salinity is a major driver of both overall microbial community structure and community structure of the denitrifying bacteria specifically; and to assess

  17. Beneficial Reuse of San Ardo Produced Water

    This DOE funded study was performed to evaluate the potential for treatment and beneficial reuse of produced water from the San Ardo oilfield in Monterey County, CA. The potential benefits of a successful full-scale implementation of this project include improvements in oil production efficiency and additional recoverable oil reserves as well as the addition of a new reclaimed water resource. The overall project was conducted in two Phases. Phase I identified and evaluated potential end uses for the treated produced water, established treated water quality objectives, reviewed regulations related to treatment, transport, storage and use of the treated produced water, and investigated various water treatment technology options. Phase II involved the construction and operation of a small-scale water treatment pilot facility to evaluate the process's performance on produced water from the San Ardo oilfield. Cost estimates for a potential full-scale facility were also developed. Potential end uses identified for the treated water include (1) agricultural use near the oilfield, (2) use by Monterey County Water Resources Agency (MCWRA) for the Salinas Valley Water Project or Castroville Seawater Intrusion Project, (3) industrial or power plant use in King City, and (4) use for wetlands creation in the Salinas Basin. All of these uses were found to have major obstacles that prevent full-scale implementation. An additional option for potential reuse of the treated produced water was subsequently identified. That option involves using the treated produced water to recharge groundwater in the vicinity of the oil field. The recharge option may avoid the limitations that the other reuse options face. The water treatment pilot process utilized: (1) warm precipitation softening to remove hardness and silica, (2) evaporative cooling to meet downstream temperature limitations and facilitate removal of ammonia, and (3) reverse osmosis (RO) for removal of dissolved salts, boron

    The San Francisco gartersnake Thamnophis sirtalis tetrataenia has been federally listed as endangered since 1967, but little demographic information exists for this species. We examined the demography of a San Francisco gartersnake population on approximately 213 ha of California coastal prairie in San Mateo County, California, from 2007 to 2010. The best-supported mark-recapture model indicated annual variation in daily capture probabilities and annual survival rates. Abundance increased throughout the study period, with a mean total population from 2008 to 2010 of 443 (95% CI = 313-646) individuals. Annual survival was slightly greater than that of most other gartersnakes, with an annual probability of survival of 0.78 (0.55-0.95) in 2008-2009 and 0.75 (0.49-0.93) in 2009-2010. Mean annual per capita recruitment rates were 0.73 (0.02-2.50) in 2008-2009 and 0.47 (0.02-1.42) in 2009-2010. From 2008 to 2010, the probability of an increase in abundance at this site was 0.873, with an estimated increase of 115 (-82 to 326) individuals. The estimated population growth rate in 2008-2009 was 1.52 (0.73-3.29) and in 2009-2010 was 1.21 (0.70-2.17). Although this population is probably stable or increasing in the short term, long-term studies of the status of the San Francisco gartersnake at other sites are required to estimate population trends and to elucidate mechanisms that promote the recovery of this charismatic member of our native herpetofauna.

  20. San Onofre - the evolution of outage management

    International Nuclear Information System (INIS)

    With the addition of units 2 and 3 to San Onofre nuclear station in 1983 and 1984, it became evident that a separate group was needed to manage outages. Despite early establishment of a division to handle outages, it was a difficult journey to make the changes to achieve short outages. Early organizational emphasis was on developing an error-free operating environment and work culture. This is difficult for a relatively large organization at a three-unit site. The work processes and decision styles were designed to be very deliberate with many checks and balances. The organization leadership and accountability were focused in the traditional operations, maintenance, and engineering divisions. Later, our organization emphasis shifted to achieving engineering excellence. With a sound foundation of operating and engineering excellence, our organizational focus has turned to achieving quality outages. This means accomplishing the right work in a shorter duration and having the units run until the next refueling

    1971-01-01

    Isla San Cristobal, the most easterly of the Galapagos Islands, consists of two parts: a large volcano constitutes the southwest half of the island and an irregular apron of small cones and flows makes up the northeast half. As some of the younger flows on the flanks of the large volcano are reversely magnetized, the minimum age of the volcano is 0.7 my, which is the age of the Brunhes-Matuyama reversal boundary. The true age is probably several times greater. The cones and flows to the northeast are all normally magnetized. The between-site angular dispersion of virtual poles is 11.3?? - a value consistent with mathematical models for the latitude dependence of geomagnetic secular variation. ?? 1971.

    A study was conducted to determine the suitability of the San Fernando Observatory's 61 cm (24 inch) aperture vacuum solar telescope and 3 m (118 inch) focal length vacuum spectroheliograph for Stokes Polarimetry measurements. The polarization characteristics of these two instruments was measured by determining their Mueller matrices as a function of telescope orientation, field angle, wavelength, grating type, and position of the measuring beam in the telescope entrance window. In general, the polarizing and depolarizing properties are small so that inversion of the system Mueller matrix will permit the accurate measurement of Stokes profiles for vector magnetic field determination. A proposed polarimeter design based on the use of a TV camera system to simultaneously scan six different polarization components of a given line profile is described. This design, which uses no rotating optics or electronic modulators and makes efficient use of the available irradiance, promises to yield high quality vector magnetograms.

    The lower Eocene San Jose Formation in the central portion of the San Juan basin (Gobernador-Vigas Canyon area) consists of the Cuba Mesa, Regina, Llaves, and Tapicitos Members. Well log data indicate that, from its 100-m thickness, the Cuba Mesa Member thins toward the basin center and pinches out to the northeast by lat. 36{degree}40'N, long. 107{degree}19'W. The Regina Member has the most extensive outcrops in the central basin, and it decreases in sandstone/mud rock ratio to the north. The Llaves and Tapicitos Members occur only at the highest elevations, are thin due to erosion, and are not mappable as separate units. Well log data and 1,275 m of measured stratigraphic section in the Regina, Llaves, and Tapicitos Members indicate these strata are composed of approximately 35% medium to coarse-grained sandstone and 65% fine-grained sandstone and mud rock. Sedimentology and sediment-dispersal patterns indicate deposition by generally south-flowing streams that had sources to the northwest, northeast, and east. Low-sinuosity, sand-bedded, braided( ) streams shifted laterally across about 1 km-wide channel belts to produce sheet sandstones that are prominent throughout the San Jose Formation. Subtle levees separated channel environments from floodplain and local lacustrine areas. Avulsion relocated channels periodically to areas on the floodplain, resulting in the typically disconnected sheet sandstones within muddy overbank deposits of the Regina Member.

  5. Developing solar power programs : San Francisco's experience

    International Nuclear Information System (INIS)

    This keynote address discussed an array of solar programs initiated in government-owned buildings in San Francisco. The programs were strongly supported by the city's mayor,and the voting public. Known for its fog and varying microclimates, 11 monitoring stations were set up throughout the city to determine viable locations for the successful application of solar technologies. It was observed that 90 per cent of the available sunshine occurred in the central valley, whereas fog along the Pacific shore was problematic. Seven of the monitoring sites showed excellent results. Relationships with various city departments were described, as well as details of study loads, load profiles, electrical systems, roofs and the structural capabilities of the selected government buildings. There was a focus on developing good relations with the local utility. The Moscone Convention Center was selected for the program's flagship installation, a 675 kW solar project which eventually won the US EPA Green Power Award for 2004 and received high press coverage. Cost of the project was $4.2 million. 825,000 kWh solar electricity was generated, along with 4,500,000 kWh electricity saved annually from efficiency measures, resulting in a net reduction of 5,325,000 kWh. Savings on utilities bills for the center were an estimated $1,078,000. A pipeline of solar projects followed, with installations at a sewage treatment plant and a large recycling depot. A program of smaller sites included libraries, schools and health facilities. Details of plans to apply solar technology to a 500 acre redevelopment site in southeast San Francisco with an aging and inadequate electrical infrastructure were described. A model of efficient solar housing for the development was presented, with details of insulation, windows, heating ventilation and air-conditioning (HVAC), water heating, lighting, appliances and a 1.2 kilowatt solar system. Peak demand reductions were also presented. tabs., figs

    Full Text Available Durante el período comprendido entre 1990 y 2006, 28 pacientes fueron sometidos a resección esofágica por cáncer en el Servicio de Cirugía de Tórax del Hospital Dr. Rafael Á. Calderón Guardia. La edad promedio fue de 65 años y la relación hombre mujer, de 6 a 1. El antecedente de tabaquismo se confirmó en un 80%, etilismo en un 75% y 8 pacientes eran conocidos portadores de esófago de Barret. Disfagia, dolor epigástrico y pérdida de peso fueron los síntomas más frecuentes; siendo la epigastralgia debida a otra patología digestiva coexistente, como reflujo o enfermedad péptica. Los pacientes clasificados como estadio IIb, III y IV recibieron terapia de inducción y aunque en 3 de estos no se encontró tumor residual en la pieza quirúrgica, en 2 casos quedó tumor adherido a la aorta. A 21 pacientes se les realizó esofagectomía total con ascenso gástrico y anastomosis cervical y a 7 esofagectomía parcial con ascenso gástrico al tórax en 5 y 2 esófago-yeyuno anastomosis, una intratorácica y otra abdominal. La complicación más frecuente fue la claudicación respiratoria por bronconeumonía, que se produjo en 7 pacientes y que fue mortal en 3. Dos de estos pacientes presentaron además fuga de anastomosis, una en el cuello y otra en el tórax. A largo plazo la complicación más frecuente fue estrechez de la anastomosis, que en los 7 casos se ha manejado con dilataciones. La mortalidad quirúrgica fue del 10.7% y en los 3 casos la bronconeumonía fue la causa principal. La supervivencia a 5 y 10 años fue del 31.5% y el 18%, respectivamente.

    Full Text Available Objetivo: Comparar los resultados perinatales de las pacientes adolescentes que asisten a la consulta de control prenatal del Hospital “Dr. Rafael Ángel Calderón Guardia” con los publicados por el Centro Latinoamericano de Perinatología y Desarrollo Humano (CLAP para la población adolescente de Latinoamérica. Materiales y Métodos: Se estudiaron 360 historias clínicas de pacientes embarazadas menores de 18 años que llevaron su control prenatal en la Clínica de Adolescentes del Servicio de Ginecología y Obstetricia en el 2010. Las variables incluidas en el estudio abarcaban la atención prenatal, el parto y postparto. Para la comparación de los resultados obtenidos en la presente investigación con los reportados por el CLAP se utilizó una Prueba de Conformidad para el Contraste de Hipótesis. Se estableció como el nivel de significancia a valores de Z menores o mayores de 1,96. (p < 0.05. Resultados: El presente estudio mostró que la morbi-mortalidad materna de las pacientes adolescentes atendidas en nuestro hospital es menor a la reportada por el CLAP. Si bien, algunas patologías como las infecciones urinarias o la anemia presentaron porcentajes significativamente mayores en nuestra población. Con relación al recién nacido, no se encontraron diferencias significativas respecto al porcentaje de partos pretérmino, productos con bajo peso o muy bajo peso al nacer. El hecho de que aproximadamente el 97% de las pacientes tuvieran su parto al término o cercano a este (más de 34 semanas de gestación y el contar con una Unidad de Cuidados Intensivos Neonatales podría explicar la baja mortalidad neonatal presentada en nuestras adolescentes. Conclusiones: La morbi-mortalidad materna y neonatal de las pacientes adolescentes atendidas en nuestro hospital es menor a la reportada por el CLAP para la población adolescente.

    Full Text Available Objetivo: Analizar lo útil que ha sido el desarrollo de la toracoscopía en el Hospital Dr. Rafael A. Calderón Guardia. Materiales y métodos: Con el fin de valorar la experiencia adquirida con la cirugía mínimamente invasiva del tórax durante los primeros 10 años, se estudiaron los datos clínicos de 788 pacientes tomados de una base de datos del Servicio de Cirugía de Tórax, desde marzo de 1999 a marzo del 2009. Resultados: Se encontró que durante el período de 10 años un 25% de las intervenciones del servicio se realizaron por toracoscopia. Este porcentaje subió a un 49% durante los dos últimos años del período estudiado. Se analizaron los expedientes clínicos de los pacientes que fueron sometidos a procedimientos diagnósticos o a resecciones tumorales. En el 97.4% de los pacientes que fueron intervenidos con fines de diagnóstico se obtuvo el mismo; los tumores que resultaron de más difícil diagnóstico, fueron los del mediastino, en dos de los cuales el patólogo solicitó un espécimen más grande. No se realizaron procedimientos mayores por este método. No se dio ningún caso de mortalidad. El porcentaje de conversión fue de un 2.6% y de este 20% fue por sangrado y 80% para realizar un procedimiento mayor. Conclusión: El procedimiento de toracoscopia ha revolucionado el campo de la medicina, en donde antes se utilizaban métodos como la toracotomía para cirugías menores, esto ha permitido realizar intervenciones y procedimientos complejos. Los resultados obtenidos muestran resultados satisfactorios para el paciente y de gran utilidad para la institución.

    1994-01-01

    San Francisco Bay as seen from STS-59. View is oriented with the sea up. The delta of the combined Sacramento and San Joaquin Rivers occupies the foreground with San Francisco Bay in the middle distance, then the Pacific Ocean. Variations in water color caused both by sediment load and by wind streaking strike the eye. Man-made features dominate this scene. The Lafayette/Concord complex is left of the bay head, Vallejo is to the right, the Berkeley/Oakland complex rims the shoreline of the main bay, and San Francisco fills the peninsula beyond. Salt-evaporation ponds contain differently-colored algae depending on salinity. The low altitude (less than 120 nautical miles) and unusually-clear air combine to provide unusually-strong green colors in this Spring scene.

  5. Microstructure of magnetite doped elastomers investigated by SAXS and SANS

    International Nuclear Information System (INIS)

    Some recent results on the SAXS and SANS investigations of the magnetic elastomers are presented. Samples were obtained by polymerizing dimethylsiloxane with Fe3O4 ferrofluid in a magnetic field and without magnetic field and characterized by XRD, SANS and SAXS. The SAXS maximum at large angles, obtained from magnetic elastomers, was fitted by using a Pseudo-Voigt function. It was found that the Fe3O4 particles lead to a change of the local structure of the elastomer, meaning the decrease of the quasi-crystalline phase and of the microstrains induced in the matrix. The average particle size obtained from SANS measurements agrees well with the average particle size determined by XRD and SAXS analysis. The splitting of the SANS intensity owing to an additional scattering in zero field reflects the existence of magnetic correlations inside the Q region of 0.005 -1

    1993-01-01

    This sharp cloud-free photograph of San Antonio, Texas illustrates the classic pattern of western cities. The Hispanic heart of the city, an intertwining of streets along the San Antonio River and around the Alamo, surrounded by a late 19th century Anglo grid of small businesses and suburban homes. Transportation routes radiate to mid and late 20th century ring corridors separating the urban/suburban region from the surrounding agricultural countryside. Limestone quarries are conspicuous along the edge of the Balcones Escarpment, at the foot of which San Antonio was founded. Randolph Air Force Base is outside the city to the northeast, Fort Sam Houston is contained within the northeast quadrant of the city, Brooks Air Force Base lies at the southeastern corner, and Lackland and Kelly Air Force Bases are within the suburban fringe to the southwest. San Antonio International Airport can be seen at the foot of the escarpment in the northern part of the city.

    Full Text Available The Crown Zellerbach has been built on a large triangular plaza, at the outskirts of San Francisco. This is one of the most recent tall buildings in the city. The Wells Fargo Bank is also situated on this plaza. It is of special interest, both as regards its shape and functional organisation. It has a ground floor, where most of the mercantile activities take place, and a basement, containing a Council room; the strong rooms, with 2,500 private boxes as well as the bank's own safe; washing rooms; mechanical equipment rooms; a rest room; a bar for the employees and independent stairs. The building has a circular planform, 21.5 m in diameter and 354 m2 in area. The structure is metallic, the vertical supports are along the periphery, spaced every 1.626 m. The enclosing curtain walls are glass and anodized aluminium. The roof has radially distributed metal beams, interconnected by prefabricated concrete units, covered with copper sheeting. This bank, shaped like a hunting lodge, and finished with delicate care, contrasts sharply with the powerful volume of the Crown Zellerbach, and of other nearby buildings, and adds distinction to the plaza.Sobre una gran plaza triangular del extrarradio de San Francisco se alzan: el Crown Zellerbach, uno de sus más recientes rascacielos, y un bello pabellón independiente, el Wells Fargo Bank.

  2. Preliminary analysis of SANS data from hydrated cement paste

    International Nuclear Information System (INIS)

    Full text: The microstructure of hydrated cement paste is investigated using the technique of Small Angle Neutron Scattering (SANS). The results from SANS measurements are dependent upon the thicknesses of the target materials. Reduction of target thickness is usually not a practical proposition owing to the difficulty in preparing sufficiently thin cement samples and also to the subsequent low count rates of the scattered beam relative to the transmitted beam. In this paper we present a method of analysis that takes advantage of the process of multiple scattering in thick samples. Using cement specimens, which are of different thicknesses, but are otherwise identical, SANS patterns with different degrees of multiple scattering have been obtained. It is shown how these measurements not only provide information about the shape and size of the scattering entities but also provide absolute values of the scattering contrast between the entities responsible for SANS and the matrix. This method of analysis has been used to analyse SANS data from hydrated cement paste. The data were collected on the Ultra High Resolution SANS Diffractometer at Oak Ridge National Laboratory, USA

  7. SYNROC densification: SEM correlation to SANS

    International Nuclear Information System (INIS)

    SYNROC is among the first crystalline waste forms introduced to radioactive waste management as alternative host to glass for disposal in underground repository. Variation of densification parameters obtained from scanning electron microscopy of microstructure and small-angle neutron scattering investigation has been correlated in the present paper. Three specimens of SYNROC were characterized. One was green pellet uniaxially compacted powder, two others were hot-isostatically compacted at 1000℃ 1000 bar and 1300℃ 1000 bar 2h dwell time respectively. The compactness was found to increase with sintering. The SEM image of microstructures showed the progress towards densification of the samples. The SANS profile suggested that pores in three widely separated length scales were present in the samples. The average radius of the size distributions at three length scales for the green pellet was 300 nm, 75 nm and 10 nm. These values for the first hot compacted sample, get modified to 126 nm, 73 nm and 20 nm, respectively. For the second hot compacted sample, the average radius of the pore size distributions become as 84 nm, 80 nm and 20 nm. It is evident that the larger diameter pores follow the trend of densification. The bigger pores from SEM imaged microstructures also follow the same trend of densification

  8. Teaching Geology at San Quentin State Prison

    2004-12-01

    The students enrolled in our Geology 215 class are about as on-traditional as it gets. They range in age from about 20 - 50 years old, they are all male, all from under-represented ethnic groups, and they are all serving time in one of the country's most notorious prisons. We teach in a degree-granting community college program inside California's San Quentin State Prison. The program is run entirely by volunteers, and students who participate in educational programs like ours are about 5 times less likely to return to prison than the general inmate population in California. The prison population of California is ethnically diverse, though minorities are present in higher proportion than in the general population. Last semester, our geology class happened to be composed entirely of minorities even though the college program serves the full spectrum of the prison population. While some trends in geoscience education encourage the use of technology in the classroom, security restrictions prevent us from using even some of the simplest visual aids. Faced with these challenges, we have developed an inquiry-based syllabus for an introductory Geology class at the community college level. We find that kinaesthetic learning activities such as urban geologic mapping and acting out plate tectonic motions from ridge to trench (complete with magnetic pole polarity shifts) are not only possible in restricted learning environments, but they promote student learning in unexpected ways.

  10. Mercury in San Francisco Bay forage fish

    International Nuclear Information System (INIS)

    In the San Francisco Estuary, management actions including tidal marsh restoration could change fish mercury (Hg) concentrations. From 2005 to 2007, small forage fish were collected and analyzed to identify spatial and interannual variation in biotic methylmercury (MeHg) exposure. The average whole body total Hg concentration was 0.052 μg g-1 (wet-weight) for 457 composite samples representing 13 fish species. MeHg constituted 94% of total Hg. At a given length, Hg concentrations were higher in nearshore mudflat and wetland species (Clevelandia ios, Menidia audens, and Ilypnus gilberti), compared to species that move offshore (e.g., Atherinops affinis and Lepidogobius lepidus). Gut content analysis indicated similar diets between Atherinops affinis and Menidia audens, when sampled at the same locations. Hg concentrations were higher in sites closest to the Guadalupe River, which drains a watershed impacted by historic Hg mining. Results demonstrate that despite differences among years and fish species, nearshore forage fish exhibit consistent Hg spatial gradients. - Total mercury in estuarine forage fish varies with species, habitat, and proximity to a historic mercury mine.

  11. Trans Women Doing Sex in San Francisco.

    This research investigates the sexuality of trans women (individuals who were assigned male status at birth who currently identify as women), by focusing on the "bodily techniques" (Crossley, 2006) they use in "doing" sexuality. The "doing sexuality" framework not only is modeled after the "doing gender" approach of West and Zimmerman (1987), but also utilizes the idea of "sexual embodiment" to emphasize the agency of trans women as they conceptualize and organize their sexuality in a socially recognized way. This is often difficult as they confront discrimination from medical and legal professionals as well as intimate partners who may find it difficult to adapt to the trans woman's atypical body and conception of gender. However, with a study group of 25 trans women from San Francisco, we found the study participants to be adept at overcoming such hurdles and developing techniques to "do" their sexuality. At the same time, we found trans women's agency constrained by the erotic habitus (Green, 2008) of the wider society. The interplay between innovation and cultural tradition provides an opportunity to fashion a more general model of "doing" sexuality. PMID:27091188

  12. Neutron Beam Conditioning for Focusing SANS Spectrometers

    Energy Technology Data Exchange (ETDEWEB)

    Fuezi, Janos; Rosta, Laszlo, E-mail: fuzi@szfki.hu

    2010-11-01

    Multibeam focusing offers an appealing compromise between high resolution and high incident flux configurations for SANS spectrometers. In fact so many 'spectrometers' operate in parallel as the number of channels in the collimator. Each channel provides high resolution by small spot size on the detector and long sample-to-detector distance, involving significant limitation of the transmitted beam phase space volume, thus reducing the flux. The flux on the sample is increased by the large number of channels. In view of the multibeam collimation it is beneficial to increase the beam cross section and decrease the divergence at the same time. Two aspects related to the use of rotational velocity selectors are investigated. First the transmitted phase space is determined from the selector parameters. It is found that the beam azimuthal divergence with respect to the rotor axis has a significant effect on the selectivity. Neutrons flying along different paths are treated differently, leading eventually to energetic non-uniformity of the illumination of various collimator channels. Then the effect of the gap in the neutron guide at the selector location on the phase space uniformity at the collimator entrance is investigated and optimal selector location along the beam is proposed together with optimal neutron guide shape in the vicinity of the gap, which accommodates the selector.

    Pakkala, P. A.

    The San Anselmo School is a one story brick elementary school building in San Jose, California. The active solar energy system is designed to supply 70% of the space heating and 72% of the cooling load. It is equipped with 3740 square feet of evacuated tube collectors, a 2175 gallon tank for heat storage, a solar supplied absorption chiller, and four auxiliary gas fired absorption chillers/heaters. The measured solar fraction of 19% is far below the expected values and is attributed to severe system control and HVAC problems. Other performance data given for the year include the solar savings ratio, conventional fuel savings, system performance factor, and solar system coefficient of performance. Also tabulated are monthly performance data for the overall solar energy system, collector subsystem, space heating and cooling subsystems. Typical hourly operation data for a day are tabulated, including hourly isolation, collector array temperatures (inlet and outlet), and storage fluid temperatures. The solar energy use and percentage of losses are also graphed.

    Extending 4 km into the Earth along a diagonal path that crosses the divide between Salinian basement accreted to the Pacific Plate and Cretaceous sediments of North America, the main hole at the San Andreas Fault Observatory at Depth (SAFOD) was designed to provide a portal into the inner workings of a major plate boundary fault. The successful drilling and casing of the main hole in the summer of 2005 to a total vertical depth of 3.1 km make it possible to conduct spatially extensive and long-duration observations of active tectonic processes within the actively deforming core of the San Andreas Fault. In brief, the observatory consists of retrievable seismic, deformation and environmental sensors deployed inside the casing in both the main hole (maximum temperature 135 C) and the collocated pilot hole (1.1 km depth), and a fiber optic strainmeter installed behind casing in the main hole. By using retrievable systems deployed on either wire line or rigid tubing, each hole can be used for a wide range of scientific purposes, with instrumentation that takes maximum advantage of advances in sensor technology. To meet the scientific and technical challenges of building the observatory, borehole instrumentation systems developed for use in the petroleum industry and by the academic community in other deep research boreholes have been deployed in the SAFOD pilot hole and main hole over the past year. These systems included 15Hz omni-directional and 4.5 Hz gimbaled seismometers, micro-electro-mechanical accelerometers, tiltmeters, sigma-delta digitizers, and a fiber optic interferometeric strainmeter. A 1200-m-long, 3-component 80-level clamped seismic array was also operated in the main hole for 2 weeks of recording in May of 2005, collecting continuous seismic data at 4000 sps. Some of the observational highlights include capturing one of the M 2 SAFOD target repeating earthquakes in the near-field at a distance of 420 m, with accelerations of up to 200 cm/s and a

    Heavy metals are natural elements that generally occur in minute concentrations in the earth's crust. While some of these elements, in small quantities, are vital to life, most are harmful in larger doses. Various industrial and agricultural processes can result in dangerously high concentrations of heavy metals in our environment. Consequently, humans can be exposed to unsafe levels of these elements via the air we breathe, the water and food we consume, and the many products we use. During a two week study we collected numerous samples of sediments, water, food, and household items from around the San Francisco Bay Area that represent industrial, agricultural, and urban/residential settings. We analyzed these samples for Mercury (Hg), Lead (Pb), and Arsenic (As). Our goal was to examine the extent of our exposure to heavy metals in our daily lives. We discovered that many of the common foods and materials in our lives have become contaminated with unhealthy concentrations of these metals. Of our food samples, many exceeded the EPA's Maximum Contaminant Levels (MCL) set for each metal. Meats (fish, chicken, and beef) had higher amounts of each metal than did non-meat items. Heavy metals were also prevalent in varying concentrations in the environment. While many of our samples exceeded the EPA's Sediment Screening Level (SSL) for As, only two other samples surpassed the SSL set for Pb, and zero of our samples exceeded the SSL for Hg. Because of the serious health effects that can result from over-exposure to heavy metals, the information obtained in this study should be used to influence our future dietary and recreational habits.

    Full Text Available The aim of this study is to elucidate butterfly fauna in Mt. Gariwang-san, Korea. A field survey was conducted from 2010 to 2015 using the line transect method. A literature survey was also conducted. A total of 2,037 butterflies belonging to 105 species were recorded. In the estimation of species richness of butterfly, 116 species were estimated to live in Mt. Gariwang-san. In butterfly fauna in Mt. Gariwang-san, the percentage of northern species was very high and the percentage of grassland species was relatively higher than that of forest edge species and forest interior species. Sixteen red list species were found. In particular, Mimathyma nycteis was only recorded in Mt. Gariwang-san. When comparing the percentage of northern species and southern species including those recorded in previous studies, the percentage of northern species was found to have decreased significantly whereas that of southern species increased. We suggest that the butterfly community, which is distributed at relatively high altitudes on Mt. Gariwang-san, will gradually change in response to climate change.

  17. High-resolution SANS experiments by double-crystal technique

    International Nuclear Information System (INIS)

    Though small-angle scattering is a method suitable for investigation of microstructure in a wide mesoscopic size range (about 1 nm to 1 μm), the dynamic Q-range in a single SANS spectrum - defined as the ratio of the maximum value of the scattering vector Q to the Q-resolution of the instrument - is rarely better than about 10. The combination of measurements performed at different Q regions is therefore necessary for better evaluation of SANS experiments, particularly in case of polydisperse systems. Variation of instrument length, slit sizes and neutron wavelength is the usual way how to extend the Q-range accessible at a conventional pinhole SANS instrument. Nevertheless, this possibility is limited on the side of small Q values because of restrictions imposed on the physical length and luminosity of SANS facilities even if they are equipped with an efficient cold neutron source. Alternative techniques for SANS investigation of large objects requiring ultra high resolution were developed, based on the nondispersive arrangement of two perfect crystals. This contribution is focused on the double bent crystal (DBC) diffractometers operating in the intermediate Q-range of 10-4 to 10-2 A-1, which is difficult to access by both the types of instruments mentioned above.

    1980-01-01

    The solar energy system, Elcam San Diego, was designed to supply domestic hot water heating for a single family residence located in Encinitas, California. System description, performance assessment, operating energy, energy savings, maintenance, and conclusions are presented. The system is a 'Sunspot' two tank cascade type, where solar energy is supplied to either a 66 gallon preheat tank (solar storage) or a 40 gallon domestic hot water tank. Water is pumped directly from one of the two tanks, through the 65 square feet collector array and back into the same tank. Freeze protection is provided by automatically circulating hot water from the hot water tank through the collectors and exposed plumbing when freezing conditions exist. Auxiliary energy is supplied by natural gas. Analysis is based on instrumented system data monitored and collected for one full season of operation.

  19. Holocene Geologic Slip Rate for the Banning Strand of the Southern San Andreas Fault near San Gorgonio Pass, Southern California

    We present the first Holocene geologic slip rate for the Banning strand of the southern San Andreas Fault in southern California. The southern San Andreas Fault splays into the sub-parallel Banning and Mission Creek strands in the northwestern Coachella Valley, and although it has long been surmised that the Banning strand eventually accommodates the majority of displacement and transfers it into San Gorgonio Pass, until now it has been uncertain how slip is actually partitioned between these two fault strands. Our new slip rate measurement, critically located at the northwestern end of the Banning strand, overlaps within errors with the published rate for the southern San Andreas Fault measured at Biskra Palms Oasis. This indicates that the majority of southern San Andreas Fault displacement transfers from the southeastern Mission Creek strand northwest to the Banning strand and into San Gorgonio Pass. Our result corroborates the UCERF3 hazard model, and is consistent with most previous interpretations of how slip is partitioned between the Banning and Mission Creek fault strands. To measure this slip rate, we used B4 airborne LiDAR to identify the apex of an alluvial fan offset laterally 30 ± 5 m from its source. We calculated the depositional age of the fan using 10Be in-situ cosmogenic exposure dating of 5 cobbles and a depth profile. We calculated a most probable fan age of 4.0 +2.0/-1.6 ka (1σ) by combining the inheritance-corrected cobble ages assuming Gaussian uncertainty. However, the probability density function yielded a multi-peaked distribution, which we attribute to variable 10Be inheritance in the cobbles, so we favor the depth profile age of 2.2-3.6 ka. Combined, these measurements yield a late Holocene slip rate for the Banning strand of the southern San Andreas Fault of 11.1 +3.1/-3.3 mm/yr. This slip rate does not preclude possibility that some slip transfers north along the Mission Creek strand and the Garnet Hill fault, but it does confirm

    An improved understanding of the time history of fault slip at depth is an essential step toward understanding the underlying mechanics of the faulting process. Using a waveform cross-correlation approach, we document spatially and temporally varying fault slip along the northernmost creeping section of the San Andreas Fault near San Juan Bautista (SJB), California, by systematically examining spatiotemporal behaviors of characteristically repeating earthquakes (CREs). The spatial distribution of pre-1998 SJB earthquake (1984-1998) fault slip rate inferred from the CREs reveals a ~15 km long low creep or partially locked section located near the 1998 Mw 5.1 SJB earthquake rupture. A finite-fault slip inversion reveals that the rupture of the 1998 SJB earthquake is characterized by the failure of a compact ~4 km2 asperity with a maximum slip of about 90 cm and corresponding peak stress drop of up to 50 MPa, whereas the mean stress drop is about 15 MPa. Following the 1998 earthquake, the CRE activity was significantly increased in a 5-10 km deep zone extending 2-7 km northwest of the main shock, which indicates triggering of substantial aseismic slip. The postseismic slip inferred from the CRE activity primarily propagated to the northwest and released a maximum slip of 9 cm. In this 5-10 km depth range, the estimated postseismic moment release is 8.6 × 1016 N m, which is equivalent to Mw 5.22. The aseismic slip distribution following the 1998 earthquake is not consistent with coseismic stress-driven afterslip but represents a triggered, long-lasting slow earthquake.

    The extended Q-range small angle neutron scattering (EQ-SANS) diffractometer at the Spallation Neutron Source has recently been completed. Initial commissioning has shown that it has achieved its high intensity, low background, and wide dynamic range design goals. One of the key components that enable these performances is its neutron optics, which are extensively optimized using analytical and Monte Carlo methods. The EQ-SANS optics consist of a curved multichannel beam bender and sections of straight neutron guides on both ends of the bender. The bender and the guide are made of float glass coated with supermirror multilayers. The function of the optics is to ensure low instrument background by avoiding the direct line of sight of the neutron moderator at downstream locations, while transporting thermal and cold neutrons to the sample with maximum efficiency. In this work, the optimization of the EQ-SANS optics is presented.

  3. SANS facility at the PITESTI 14MW TRIGA reactor

    International Nuclear Information System (INIS)

    At the present time, an important not yet fully exploited potentiality is represented by the SANS instruments existent at lower power reactors and reactors in developing countries even if they are, generally, endowed with a simpler equipment and are characterized by the lack of infrastructure to maintain and repair high technology accessories. The application of SANS at lower power reactors and in developing countries nevertheless is possible in well selected topics where only a restricted Q range is required, when scattering power is expected to be sufficiently high or when the sample size can be increased at the expense of resolution. The need for the installation of a new SANS facility at the Triga Reactor of the Institute of Nuclear Researches in Pitesti, Romania become actual especially after the shutting down of the VVRS Reactor from Bucharest

    Seven species of geographically variable birds have been reported as part of the resident avifauna of San Esteban Island in the Gulf of California, Sonora. Two of these, the Curvebilled Thrasher and the Blue-gray Gnatcatcher, may not actually have breeding populations there, at least at the present time. Of the seven, only two, the Verdin and the doubtfully resident thrasher, can be used in a determination of the relationships of the avifauna, and both show affinities to that of Sonora. The Ash-throated Flycatcher and the House Finch are represented by the same form on San Esteban and in both Sonora and Baja California at the latitude of the island. Neither the Ladder-backed Woodpecker nor the endemic Black-throated Sparrow shows greater similarity to the Baja California or Sonoran avifauna. The slight balance of evidence indicates that the avifauna of San Esteban Island is best considered with that of Sonora.

    2001-01-01

    The experience gained in the last 15 years of experimental studies of large-scale structures with the SANS instrument at the IBR-2 pulsed reactor in Dubna shows that some parameters of the spectrometer can be improved. In particular, it concerns reduction of the fast neutron and gamma backgrounds that limit the possibilities of studying weakly scattering objects. Another direction of improvement is to reduce a minimum momentum transfer value Qmin to study objects with larger characteristic dimensions. The paper investigates several configurations of the SANS machine at IBR-2. The Monte Carlo codes are used to calculate the parameters of such virtual instruments. An optimal instrument structure is proposed.

  18. Investigating Fault Slip and Rheology Along the San Andreas Fault in the San Juan Bautista Region

    2012-12-01

    An improved understanding of the connection between seismic behavior and fault-zone rheology at depth is an essential step toward understanding the underlying mechanics of the faulting process. We investigate the seismicity along the northernmost creeping section of the San Andreas fault near San Juan Bautista (SJB), California, by systematically examining spatiotemporal behaviors of the aftershock sequences following the 12 August 1998 Mw 5.1 SJB earthquake. This 1998 SJB earthquake was the largest historic earthquake in the SJB area and was associated with a large slow slip event. Using a waveform cross-correlation approach (Peng and Zhao, 2009, NatureGeo), we have detected previously uncataloged earthquakes (about 500 events), resolving details of the aftershock activity in a zone at a depth of 9 km about 7 km northwest of the 1998 SJB mainshock. This aftershock zone is marked by one of the highest changes in the seismicity rate, exhibiting a delayed peak (about 20 hours after the mainshock) in the rate of aftershocks preceded by a period of very low rate of aftershocks since the mainshock. Subsequently, the rate of aftershocks shows power-law decay with time for about 1 month, and then the aftershock activity approached the pre-earthquake background level. This temporal behavior of the aftershock activity is different from the predicted aftershock decay based on the model of Dieterich (1994, JGR). Instead, our observation is more consistent with the decay rate of aftershocks occurring in the transition zone between locked and stable slip, as simulated numerically by Kaneko and Lapusta (2008, JGR). Our waveform analysis also identifies over 20 repeating microearthquake sequences (or groups of earthquakes with similar waveforms) associated with the 1998 SJB mainshock. The majority of the sequences have events occurring in the first month of the postseismic period. In other words, they reflect short-lived, accelerated repeater recurrences activated by the 1998 SJB

  20. Multiple-channel collimation for improved performance of SANS instruments

    International Nuclear Information System (INIS)

    Complete text of publication follows. Small Angle Neutron Scattering (SANS) is a powerful technique for the investigation of the submicrometer structure of condensed matter, and has found important applications in materials science and engineering, solid state physics, polymer research and biological sciences. SANS facilities are currently heavily demanded and several new such instruments are planned for installation. However, the existing facilities, due to the design adopted for the layout as well as the mode in which they operate can, in general, be upgraded. An analytical study is presented on the performance of a SANS instrument equipped with a multi-aperture pinhole collimator. This collimation can provide large count rate gains, which might attain one order of magnitude, for the usual resolution required in SANS measurements. Both pulsed and steady-state neutron sources are considered in the study. For pulsed source installation such collimation was found to be ideal because is not only provides the optimisation of count rate and resolution but it also avoids the problem of frame overlap, as relatively small collimation lengths are required. For steady-state neutron source installation the referred optimisation is achieved but the versatility in reciprocal space range becomes reduced. Finally, a new type of honeycomb collimator based on the results presented is proposed. (author)

    Heavy metal pollution in water is generally associated with industrial and municipal discharges into rivers, estuaries and lagoons. Once metals are in the water column, they may be taken up by organisms, deposited in the sediments or remain for some period in the water itself. The deposition rate in sediments depends on, among other factors, metal concentration in surface sediments. The concentrations of heavy metals in sediments of coastal, estuarine and lagoon environments have been determined by many workers. For the past several years, we have been interested in determining trace and heavy metal concentrations in the lagoons in Mexico to establish the levels of metal pollution. The work reported here is the completion of our ongoing study in San Andres lagoon. San Andres lagoon is located north of two industrial ports, Tampico and Altamira. In this industrial zone, the basins of the Panuco and Tamesi Rivers are localized and have industrial effluent throughout the year. All these activities and the input of the Tigre River, which runs through an agricultural and cattle-raising region, may affect the biogeochemistry of the San Andres lagoon. In the present work, we report concentrations of Cd, Co, Cu, Fe, Mn, Ni, Zn and Pb in sediments of San Andres lagoon. The measurements were made in different seasons; Rain-84 (August-September 1984); North (October-December 1984); Dry (April 1985); and Rain-85 (April-June 1985). 13 refs., 1 fig., 2 tabs.

    Green photosynthetic bacteria harvest light and perform photosynthesis in low light environments, and contain specialized antenna complexes to adapt to this condition. In this report, we present studies using small-angle neutron scattering (SANS) to elucidate structural information about the photosynthetic apparatus, including the peripheral light harvesting chlorosome complex, the integral membrane light-harvesting B808-866 complex and the reaction center (RC) in the thermophilic green phototrophic bacterium Chloroflexus aurantiacus. Using contract variation in SANS measurments, our studies suggest that the B808-866 comples is wrapped around the RC in Cfx. aurantiacus, and the overall size and conformation for the B808-866 complex of Cfx. aurantiacus is roughly comparable to the LH1 antenna complex of the purple bacteria. A similar size for the isolated B808-866 complex is also suggested via dynamic light scattering measurements. Alos, a smaller size of the RC of Cfx. aurantiacus that the RC of the purple bacteria is observed. Further, our SANS measurements indicate that the chlorosome is a lipid body with rod-like shape, and that the self-assembly of bacteriochlorophylls, the major component of the chlorosome, is lipid-like. Finally, two populations of chlorosome particles are suggested in our SANS measurements.

    Changes in the ground elevation observed before and immediately after the 1971 San Fernando, California, earthquake are consistent with a theoretical model in which fault zone rocks are strain-softening after peak stress. The model implies that the slip rate of the fault increased to about 0.1 meter per year near the focus before the earthquake.

  10. The analysis of multiple scattering in SANS and USANS measurements

    International Nuclear Information System (INIS)

    Full text: Small-angle neutron scattering (SANS) and ultra-small-angle neutron scattering (USANS) are widely used to investigate the micro- and nano-structure of condensed matter. However, measurements on materials such as cements, clays etc. are often affected by multiple scattering. If a substantial number of neutrons experience more than one scattering event within a sample, the result is broadening of the angular distribution profile. Often samples cannot be made thin enough to guarantee single scattering and even in cases where it is possible to make thin samples, surface effects can sometimes lead to results that are not representative of the bulk material. In addition, for many SANS measurements there is no reliable method for determining whether or not a sample is thin enough to produce mainly single scattering. Even SANS measurements from samples with different thicknesses may not reveal the presence or otherwise of multiple scattering. We will show that the problems presented by multiple scattering can often be overcome by using USANS measurements. USANS data from different thickness samples often allow us to quantify the effects from multiple scattering. Rather than trying to eliminate multiple scattering from SANS and USANS experiments, it is more advantageous to use multiple scattering to extract information from these measurements that would otherwise be impossible, or at least more difficult, to obtain

    International Nuclear Information System (INIS)

    The objective of the present study, was to elaborate a profile of the contamination by private matter and to characterize the aerosols collected in the Metropolitan Area of San Jose (Costa Rica). For that, a campaign of sampling was carried out in three points of the city of San Jose, differentiated by there degree of activity: Center of San Jose (Central Station of Firemen), San Isidro of Coronado -Canton of Vasquez of Coronado- (Municipality) and Escazu (Municipality). Such campaign was carried out from April 4 to July 4, 1996 (transition summer-winter), and in two periods of time of 8 hours: 8 a.m. to 4 p.m. and of 8 p.m. to 4 a.m. The aerosols were collected utilizing Gent Pm-10 samplers, in filters of polycarbonate of 0,4 μm and 8 μm in cascade, with a flow average of 15 L/min., and it determined the composition average of the present aerosols. The concentration of the majority of the anions were obtained by means of ionic chromatography of high resolution, and the main cations by spectrophotometry of atomic absorption with electro thermic atomization. The space-temporary variations of the concentrations were evaluated and their correlation with the meteorologic variable. (S. Grainger)

    Heron's Head Park, formerly known as Pier 98, is a 24-acre restored wetland, owned and operated by the Port of San Francisco and situated at the base of the Hunter's Point Power Plant. Heron's Head is a unique environment that is built on landfill and is now a thriving marsh maintained primarily by youth and community volunteers. Adjacent to the park stands a PG&E power plant (closed May 2006), a county waste transfer station, and a combined sewer overflow (CSO) pipe. The park is bordered by San Francisco Bay on the north, east and south sides of the park. We examined the levels of ammonia, nitrite, nitrate, phosphate and fecal coliform at nine sites around the park. Utilizing historical data from other San Francisco Bay sites and other similar estuarine settings in California, we assessed the health of the Bay waters surrounding the park. We found the levels of ammonia, nitrate, nitrite and phosphates to be within the parameters of historical San Francisco Bay data and similar to settings such as Elkhorn Slough, Tomales Bay and Tijuana Estuary. In our study we did find a potential hazard to human health. Fecal coliform concentrations in waters that border the park range from 340 MPN/100 mL - 24,000 MPN/100 mL. This level significantly exceeds Environmental Protection Agency recommendations of 300 MPN/100 mL for human contact with water.

  19. The green areas of San Juan, Puerto Rico

    Full Text Available Green areas, also known as green infrastructure or urban vegetation, are vital to urbanites for their critical roles in mitigating urban heat island effects and climate change and for their provision of multiple ecosystem services and aesthetics. Here, I provide a high spatial resolution snapshot of the green cover distribution of the city of San Juan, Puerto Rico, by incorporating the use of morphological spatial pattern analysis (MSPA as a tool to describe the spatial pattern and connectivity of the city’s urban green areas. Analysis of a previously developed IKONOS 4-m spatial resolution classification of the city of San Juan from 2002 revealed a larger area of vegetation (green areas or green infrastructure than previously estimated by moderate spatial resolution imagery. The city as a whole had approximately 42% green cover and 55% impervious surfaces. Although the city appeared greener in its southern upland sector compared to the northern coastal section, where most built-up urban areas occurred (66% impervious surfaces, northern San Juan had 677 ha more green area cover dispersed across the city than the southern component. MSPA revealed that most forest cover occurred as edges and cores, and green areas were most commonly forest cores, with larger predominance in the southern sector of the municipality. In dense, built-up, urban land, most of the green areas occurred in private yards as islets. When compared to other cities across the United States, San Juan was most similar in green cover features to Boston, Massachusetts, and Miami, Florida. Per capita green space for San Juan (122.2 m²/inhabitant was also comparable to these two U.S. cities. This study explores the intra-urban vegetation variation in the city of San Juan, which is generally overlooked by moderate spatial resolution classifications in Puerto Rico. It serves as a starting point for green infrastructure mapping and landscape pattern analysis of the urban green spaces

  20. 3D Geologic Model of the San Diego Area

    2015-12-01

    Prior geologic studies of the San Diego area, including northern Baja California, Mexico, focused on site investigations, characterization of rock formations, or earthquake hazards. No comprehensive, quantitative model characterizing the three-dimensional (3D) geology of the entire area has been developed. The lack of such a model limits understanding of large-scale processes, such as development of ancient landforms, and groundwater movement and availability. To evaluate these regional processes, the United States Geological Survey (USGS) conducted a study to better understand the geologic structure of the San Diego area. A cornerstone of this study is the installation and analysis of 77 wells at 12 multiple-depth monitoring-well sites. Geologic information from these wells was combined with lithologic data from 81 oil exploration wells and municipal and private water wells, gravity and seismic interpretations, and paleontological interpretations. These data were analyzed in conjunction with geologic maps and digital elevation models to develop a 3D geologic model of the San Diego area, in particular of the San Diego embayment. Existing interpretations of regional surficial geology, faulting, and tectonic history provided the framework for this model, which was refined by independent evaluation of subsurface geology. Geologic formations were simplified into five sedimentary units (Quaternary, Plio-Pleistocene, Oligocene, Eocene and Cretaceous ages), and one basal crystalline unit (primarily Cretaceous and Jurassic). Complex fault systems are represented in the model by ten fault strands that maintain overall displacement. The 3D geologic model corroborates existing geologic concepts of the San Diego area, refines the extent of subsurface geology, and allows users to holistically evaluate subsurface structures and regional hydrogeology.

  6. Hydrostratigraphy of the Westside Groundwater Basin, San Francisco and San Mateo Counties, California

    Science.gov (United States)

    Rogge, E. H.; Laforce, M. J.

    2002-12-01

    The Westside Groundwater Basin is a coastal aquifer system located on the San Francisco Peninsula between Golden Gate Park and Burlingame. Since the beginning of the 20th century groundwater from the Basin has been used for drinking water and irrigation purposes. Unfortunately, the Basin wide potentiometric surface has gradually declined and saltwater intrusion from the Pacific Ocean is threatening this fragile aquifer system. Several studies have looked at groundwater movement within the Basin (Boone, Cook and Associates (1987), Yates et al. (1990), Applied Consultants (1991), Geo/Resources Consultants (1993), Phillips et al. (1993), CH2Mhill (1997)); unfortunately, all of the studies assumed horizontal layering of the hydrostratigraphic units. However, recent studies indicate that tectonic deformation and intense folding has altered the stratigraphy of the Westside Basin close to the Pacific Ocean (Bonilla (1998), Barr (1999)). Accordingly, the purpose of this study is to delineate hydrostratigraphic units within the Westside Basin by using tritium, helium, and oxygen isotopes in conjunction with general mineral water quality data, water level data, and geologic cross-sections to depict the subsurface hydrogeology of the system. Our results indicate that the upper part of the Merced Formation (sequences P through Z of Clifton and Hunter (1991, 1999)) forms the major hydrostratigraphic units where groundwater is extracted, and that the Serra Fault separates the upper part of the Merced from the lower part (below sequence P) along most of its extent. In addition, thick clay layers, observed in well logs and identified in cross sections, were tentatively correlated with sequences W and S2. These clay layers, although discontinuous at places, work as aquitards between the hydrostratigraphic units as the difference in water chemistry and age indicates.

  7. SANS study of three-layer micellar particles

    Three-layer nanoparticles were prepared by polymerization of methyl methacrylate (MMA) in aqueous micellar solutions of poly(methyl methacrylate)-block-poly(methacrylic acid) (PMMA-b-PMA) and polystyrene-block-poly(methacrylic acid) (PS-b-PMA). The resulting polymer forms a layer on the core surface of the original micelles. SANS curves were fitted using an ellipsoidal (PMMA/PMMA/PMA) or spherical (PS/PMMA/PMA) model for the particle core. The particle size (for the presented series of the PMMA/PMMA/PMA particles, the core semiaxes ranged from 87 to 187 A and the axis ratio was about 6) can be finely tuned by variation of monomer concentration. Time-resolved SANS experiments were carried out to describe the growth of the PS/PMMA/PMA particles during polymerization. (orig.)

    We examine quantitatively the instrumental factors that affect the theoretical performance and practical application of conventional pinhole collimation and focusing optics for small-angle neutron scattering (SANS) measurements. We calculate the relative performance of pinhole collimation vis-à-vis focusing by grazing incidence elliptical mirrors and compare the results with a recent ray-tracing simulation to show that the performance gains due to focusing found in the simulation arise largely from assuming a much larger sample size. We also compare measurements of the parasitic scattering from pinhole collimation with that from focusing cylindrical quartz mirrors, and a focusing refractive optic, to stress the importance of signal-to-noise as the true measure of performance for SANS instruments.

  9. San Jacinto River oil spill: wetland bioremediation project

    International Nuclear Information System (INIS)

    Gasoline, diesel and unrefined Arabian light crude oil were accidentally released into the San Jacinto River after a series of pipelines ruptured. Natural removal processes (volatilization, dissolution, weathering), fire, and the spill clean-up effort, removed approximately 95% of the petroleum. The area where residual oil was found was an estuarine wetland on the lower San Jacinto River. Samples were collected from 21 study areas and an evaluation of the varying levels of bioremediation was conducted. Phase one has been completed and involved the evaluation of the natural recovery of oil from the spill. Phase two was still in progress and involved the addition of inorganic nutrients and the alternate electron acceptor to enhance the biodegradation of the petroleum. Results showed that biodegradation was responsible for much of the reduction of certain components in petroleum within the first 150 days. 12 refs., 8 figs

  9. Aggregate Settling Velocities in San Francisco Estuary Margins

    2015-12-01

    One way that humans impact aquatic ecosystems is by adding nutrients and contaminants, which can propagate up the food web and cause blooms and die-offs, respectively. Often, these chemicals are attached to fine sediments, and thus where sediments go, so do these anthropogenic influences. Vertical motion of sediments is important for sinking and burial, and also for indirect effects on horizontal transport. The dynamics of sinking sediment (often in aggregates) are complex, thus we need field data to test and validate existing models. San Francisco Bay is well studied and is often used as a test case for new measurement and model techniques (Barnard et al. 2013). Settling velocities for aggregates vary between 4*10-5 to 1.6*10-2 m/s along the estuary backbone (Manning and Schoellhamer 2013). Model results from South San Francisco Bay shoals suggest two populations of settling particles, one fast (ws of 9 to 5.8*10-4 m/s) and one slow (ws of < 1*10-7 to 1.4*10-5 m/s) (Brand et al. 2015). While the open waters of San Francisco Bay and other estuaries are well studied and modeled, sediment and contaminants often originate from the margin regions, and the margins remain poorly characterized. We conducted a 24 hour field experiment in a channel slough of South San Francisco Bay, and measured settling velocity, turbulence and flow, and suspended sediment concentration. At this margin location, we found average settling velocities of 4-5*10-5 m/s, and saw settling velocities decrease with decreasing suspended sediment concentration. These results are consistent with, though at the low end of, those seen along the estuary center, and they suggest that the two population model that has been successful along the shoals may also apply in the margins.

    Danggui-Shaoyao-San (DSS), also called Toki-shakuyaku-san (TJ-23) or Dangguijakyak-san (DJS), is a well-known herbal formula (Angelica sinensis (Oliv.) Diels., Ligusticum chuanxiong Hort., Paeonia lactiflora pall., Poria cocos (Schw.) Wolf, Alisma orientalis (Sam.) Juzep., Atractylodes macrocephala Koidz.), which has been widely used in oriental countries for the treatment of various gynecological diseases. Recent studies show that DSS has an effect on free radical-mediated neurological diseases and exhibits anti-inflammatory and antioxidant activities and reduces cell apoptosis in the hippocampus. In addition, DSS mediates the modulation of central monoamine neurotransmitter systems and ameliorates dysfunction of the central cholinergic nervous system and scopolamine-induced decrease in ACh levels. DSS improves the function of the dopaminergic, adrenergic, and serotonergic nervous systems. Interestingly, DSS can alleviate cognitive dysfunction of Alzheimer's disease (AD) patients, suggesting that it is a useful therapeutic agent for AD. This paper reviews the mechanism of DSS for the treatment of AD. PMID:27493835

    2015-08-01

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

    Full Text Available Currently, the environmental decision-making related to watershed preservation is oriented under the precepts of an historical environmental assessment. The objective of this research was to conduct a historical ecotoxicological assessment of the San Juan de Santiago de Cuba ecosystem. This was considered a systematic environmental monitoring which ran from 2010 to 2013, made q?uarterly. Physicochemical parameters such as electrical conductivity, total alkalinity, total hardness, pH, total solids, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were determined. All parameters of environmental risk prediction were performed using the GECOTOX program. The concentrations of Cu, Zn, Pb and Cd on three target organs (brain, gills and liver in the biomonitor adult Gambusia punctata (Poecilidae were analyzed. In this species, the effect of total protein and enzymatic activity of acetylcholinesterase as biomarkers were evaluated. In general, the parameters were outside the values set used by the Cuban quality standards. The GECOTOX program said that the waters of the San Juan ecosystem presented a high rate of risk. The highest concentrations of metals were determined in the gills, liver and brain, respectively. Biomarker values w? ere high, being higher for females. Finally, it was concluded that from one year to another all responses were ascending; thus, the San Juan ecosystem presented ecotoxicological effects in time.

  16. SANS facility at the Pitesti 14MW Triga reactor

    International Nuclear Information System (INIS)

    The SANS configuration with mechanical monochromator has significantly increased luminosity while the spatial extension of the instrument is quite reasonable. Tacking account that TRIGA reactor existing at INR Pitesti is a medium flux reactor and that the available dimension for the SANS instrument is severely limited by the dimensions of the room where the instrument has to be installed, this experimental configuration has been chosen as the most suited for the situation existing in our institute. For usual collimation values of about 30 minutes, and for an inclination angle of the monochromator axis of about 2-3 degrees, Dl/l is about 20-30%, i.e. quite reasonable value. The sample width may be fixed between 10 mm and 20 mm. The minimum value of the scattering vector is Qmin = 0.005 A-0-1 while the maximal value is Qmax = 0.5 A-0-1. The relative error is ΔQ/Qmin = 0.5. In the case of our SANS instrument a monochromatic neutron beam with 1.5 A-0 ≤ λ ≤ 5 A-0 is produced by a mechanical velocity selector with helical slots. The distance between sample and detectors plane is (5.2 m). (author)

    The San Carlos Apache Tribe (Tribe) in the interests of strengthening tribal sovereignty, becoming more energy self-sufficient, and providing improved services and economic opportunities to tribal members and San Carlos Apache Reservation (Reservation) residents and businesses, has explored a variety of options for renewable energy development. The development of renewable energy technologies and generation is consistent with the Tribe’s 2011 Strategic Plan. This Study assessed the possibilities for both commercial-scale and community-scale solar development within the southwestern portions of the Reservation around the communities of San Carlos, Peridot, and Cutter, and in the southeastern Reservation around the community of Bylas. Based on the lack of any commercial-scale electric power transmission between the Reservation and the regional transmission grid, Phase 2 of this Study greatly expanded consideration of community-scale options. Three smaller sites (Point of Pines, Dudleyville/Winkleman, and Seneca Lake) were also evaluated for community-scale solar potential. Three building complexes were identified within the Reservation where the development of site-specific facility-scale solar power would be the most beneficial and cost-effective: Apache Gold Casino/Resort, Tribal College/Skill Center, and the Dudleyville (Winkleman) Casino.

    Wetland ecosystems may serve as either a source or a sink for atmospheric carbon and greenhouse gases. This delicate carbon balance is influenced by the activity of belowground microbial communities that return carbon dioxide and methane to the atmosphere. Wetland restoration efforts in the San Francisco Bay-Delta region may help to reverse land subsidence and possibly increase carbon storage in soils. However, the effects of wetland restoration on microbial communities, which mediate soil metabolic activity and carbon cycling, are poorly studied. In an effort to better understand the underlying factors which shape the balance of carbon flux in wetland soils, we targeted the microbial communities in a suite of restored and historic wetlands in the San Francisco Bay-Delta region. Using DNA and RNA sequencing, coupled with greenhouse gas monitoring, we profiled the diversity and metabolic potential of the wetland soil microbial communities along biogeochemical and wetland age gradients. Our results show relationships among geochemical gradients, availability of electron acceptors, and microbial community composition. Our study provides the first genomic glimpse into microbial populations in natural and restored wetlands of the San Francisco Bay-Delta region and provides a valuable benchmark for future studies.

  1. A newly developed simultaneous SANS/FTIR measuring system for structural study on polymer solid states

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) is a powerful and convenient method to investigate the higher order structure of static polymer systems. SANS has increased its presence even in the research concerning time-dependent structural evolution. Although we have employed timeresolved SANS (TR-SANS) for the study on syndiotactic polystyrene (sPS) cocrystals so far, exploiting the large difference in molecular scattering length between fully deuterated and protonated compounds, recently we have tried to develop a new measuring system, which combine TR-SANS with the merit of FTIR spectroscopy, i.e., high potential of quantitative analysis of chemical constituents and high sensitivity to local structures such as chemical structure and molecular conformation, to enrich structural information and interpret SANS data in a more reliable manner. In this paper, we would like to introduce the simultaneous timeresolved SANS and FTIR (STR-SANS/FTIR) system and its application to sPS cocrystals. Fig 1(left) shows schematically our STR-SANS/FTIR measurement system, composed of an FTIR spectrometer and our own designed optical system, which enables the IR radiation and the neutron beam to impinge the sample film coaxially. The device was installed on a small-angle neutron diffractometer KWS2 at MLZ, as shown Fig. 1 (middle). The structural changes in a cocrystal of deuterated sPS (d-sPS) with triethylene glycol dimethyl ether (TEGDME) during the course of heating were followed with this system. Fig. 1(right) reproduces the changes in SANS 2D images and FTIR spectra measured in parallel. As for SANS images, the two lamellar reflections gradually decreased in intensity as the temperature increased and then increased slowly above 100°C. The infrared bands due to TEGDME significantly decreased in intensity, whereas the bands due to d-sPS remained almost unchanged. The information obtained by combining the SANS and FTIR data will be presented at the conference.

    1989-01-01

    A Mining Feasibility Study in the Area of Alto San Jorge, Department of Cordoba, Colombia, was commissioned by CARBOCOL S.A. to the Consortium Geominas-NACI. An area of 800 Ka2 was explored to define surface mining possibilities within two subareas referred to as Alto San Jorge and San Pedro Ure. Rocks of Cretaceous, Tertiary and Quaternary age crop out in the zone. In the subarea Alto San Jorge the principal structure is a syncline with a south-north direction. The San Pedro Ure subarea is formed by undulations with flanks of low dip, the most important being the San Antonio Syncline because it contains the mining block. The geological study of the surface demonstrated the existence of coal in the Oligocene Cienaga de Oro Formation and the Niocene Cerrito Formation, with potential resources of 6.3 billion tons. The subsequent exploration of the subsoil, with 20.618 m of drilling, permitted determination of demonstrated reserves in the order of 2.9 billion tons within two areas. In the sector selected for the mine plan, in the area of San Pedro-Puerto Libertador, 7.791 m of drilling was accomplished to define a demonstrated reserve of 515 million tons of coal down to a depth of 200. The combustible type coal has 5.000 cal/g. Complete mining schedules were developed at the prefeasibility level for two surface mines with productions of 1.5 MMTY and 4 MMTY. 9 figs., 3 tabs., 28 refs.

  7. De la criminalisation des travailleurs sans-papiers

    Full Text Available Nous souhaitons montrer qu’une criminalisation accrue de l’immigration se réalise en prenant appui sur la sphère du travail. Ceux que l’on appelle aujourd’hui les « sans papiers », quelle que soit la raison pour laquelle ils ont décidé d’émigrer et leur carrière migratoire, sont également pour une grande majorité d’entre eux des travailleurs « illégaux ». L’intérêt croissant du gouvernement belge pour la problématique des sans-papiers a amené les différentes inspections sociales chargées de faire respecter les droits sociaux à se concentrer de manière privilégiée sur le contentieux particulier de l’occupation de main-d’œuvre étrangère.Our aim is to argue that increased criminalization of immigration is extended to the sphere of employment too. Persons we call “sans papiers”, the illegal immigrants, no matter why they decided to migrate or which are their careers of migration, represent a vast majority of "illegal" workers too. Belgian Government’s increasing interest in the topic of illegal migrants has led various social inspections responsible of the enforcement of social rights to focus on this particular problem of the employment of foreign labourers.

  8. San Francisco Bay Sand Mining Resource Evaluation and Impact Analysis

    This paper presents results of the evaluation of potential future sand resources within certain Central San Francisco Bay (Central Bay) sand mining lease areas, as well as the potential impacts of further mining these areas for a ten-year period. The study consisted of morphological analysis using field measurements and hydrodynamic modeling, and covered a wide spectrum of physical processes including tidal and river circulation, salinity, sediment transport, and morphology. The study was conducted within the framework of an Environmental Impact Report (EIR) prepared by the California State Lands Commission (CSLC) as part of the discretionary approval process for issuing new mining leases. The results of the morphological analysis indicate a measurable depletion of sand resources in the Central Bay lease areas during the period 1997-2008, and that for the purposes of the proposed ten-year mining lease renewal, sand mining resources in Central Bay are largely limited to material already in place. The morphological analysis results also indicate that the proposed additional ten years of sand mining in the Central Bay lease areas are not likely to cause a significant impact on sediment transport and budgets in areas outside the vicinity of the lease areas, such as the San Francisco Bar, Ocean Beach, etc. Numerical modeling results, including particle tracking exercises, do indicate a net seaward transport of sand, and that a linkage exists between the mining areas and offshore areas (San Francisco Bar, Ocean Beach, etc). However, the modeling results demonstrate that the linkage is weak, and that any measurable changes in hydrodynamics, salinity and sediment transport/morphology caused by the mining activities are likely to be confined to the vicinity of the mining areas.

    The shelf and nearshore region of San Diego, California, between La Jolla cove in the north and the U.S.- Mexico border in the south, is an important ecological and economic resource. It contains two of the largest kelp forests in southern California and lies offshore miles of popular beaches. Understanding the interplay between tectonic and sedimentary processes in this area is critical because it will allow us to assess how other forcing functions such as the rapid sea level rise (2 - 3 mm/yr) and predicted climate change associated with global warming are impacting the kelp and nearshore environments. The fault architecture and sedimentary deposits offshore San Diego have been mapped using high-resolution seismic CHIRP profiling. The mapped area lies within the inner California Continental Borderland (CCB), which is characterized by a system of basins and ridges and extensive strike-slip faulting. The CHIRP data clearly images several splays of the Coronado Bank Fault Zone (CBFZ), a major fault in the area, which show recent activity in the upper 30 m of sediment with the most recent deformation at ~4 m below seafloor. Several sediment packages as deep as 50 m below the seafloor are imaged and place important constraints on tectonic deformation and sediment dispersal in the region as well as the earthquake recurrence interval on the CBFZ. Exposed and buried wavecut terraces identified on numerous CHIRP profiles, which can be correlated to terraces mapped regionally, provide insight into tectonic uplift rates and sea-level fluctuations. Finally, the extensive kelp forests offshore Mount Soledad and Point Loma occur where hardgrounds are exposed at the seafloor as a consequence of tectonic uplift. High resolution mapping offshore San Diego is providing new insight into the complex interplay between tectonics, sedimentation, and biology in this ecologically diverse region.

  11. Development and application of the San Onofre safety monitor

    International Nuclear Information System (INIS)

    Halliburton NUS Corporation (NUS) has developed a risk-based configuration management software tool for use at Southern California Edison's San Onofre Nuclear Generating Station. The software, called the Safety Monitor, calculates an estimate of current plant core damage risk based upon the plant's current operating configuration (e.g., equipment operability, system operating alignments). All data is entered and displayed in a format easily understood by plant personnel. The plant hopes to use this tool to ensure that risk is minimized during plant operations and to identify situations in which current Technical Specifications can be optimized. Plant configuration data and out-of-service time data is also automatically collected. (author)

  13. Resolving 3D magnetism in nanoparticles using polarization analyzed SANS

    International Nuclear Information System (INIS)

    Utilizing a polarized 3He cell as an analyzer we were able to perform a full polarization analysis on small-angle neutron scattering (SANS) data from an ensemble of 7 nm magnetite nanoparticles. The results led to clear separation of magnetic and nuclear scattering plus a 3D vectorial decomposition of the magnetism observed. At remanence variation in long-range magnetic correlation length was found to be highly dependent on temperature from 50 to 300 K. Additionally, we were able to compare the magnetic scattering from moments along and perpendicular to an applied field at saturation and in remanence.

    The cities of San Francisco and the East Bay are highlighted in this computer-generated perspective viewed from west of the Golden Gate. San Francisco occupies the peninsula jutting into the picture from the right. Golden Gate Park is the long rectangle near its left end and the Presidiois the green area at its tip, from which Golden Gate Bridge crosses to Marin. Treasure Island is the bright spot above San Francisco and Alcatraz Island is the small smudge below and to the left. Across the bay from San Francisco lie Berkeley (left) and Oakland (right). Mount Diablo, a landmark visible for many miles, rises in the distance at the upper right.This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 5 satellite image. Colors are from Landsat bands 3, 2, and 1 as red, green and blue, respectively. Topographic expression is exaggerated two times.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and will substantially help in analyzing the large and growing Landsat image archive.The Landsat Thematic Mapper image used here came from an on-line mosaic of Landsat images for the continental United States (http://mapus.jpl.nasa.gov), a part of NASA's Digital Earth effort.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission

  9. Deep permeability of the San Andreas Fault from San Andreas Fault Observatory at Depth (SAFOD) core samples

    2014-01-01

    The San Andreas Fault Observatory at Depth (SAFOD) scientific borehole near Parkfield, California crosses two actively creeping shear zones at a depth of 2.7 km. Core samples retrieved from these active strands consist of a foliated, Mg-clay-rich gouge containing porphyroclasts of serpentinite and sedimentary rock. The adjacent damage zone and country rocks are comprised of variably deformed, fine-grained sandstones, siltstones, and mudstones. We conducted laboratory tests to measure the permeability of representative samples from each structural unit at effective confining pressures, Pe up to the maximum estimated in situ Pe of 120 MPa. Permeability values of intact samples adjacent to the creeping strands ranged from 10−18 to 10−21 m2 at Pe = 10 MPa and decreased with applied confining pressure to 10−20–10−22 m2 at 120 MPa. Values for intact foliated gouge samples (10−21–6 × 10−23 m2 over the same pressure range) were distinctly lower than those for the surrounding rocks due to their fine-grained, clay-rich character. Permeability of both intact and crushed-and-sieved foliated gouge measured during shearing at Pe ≥ 70 MPa ranged from 2 to 4 × 10−22 m2 in the direction perpendicular to shearing and was largely insensitive to shear displacement out to a maximum displacement of 10 mm. The weak, actively-deforming foliated gouge zones have ultra-low permeability, making the active strands of the San Andreas Fault effective barriers to cross-fault fluid flow. The low matrix permeability of the San Andreas Fault creeping zones and adjacent rock combined with observations of abundant fractures in the core over a range of scales suggests that fluid flow outside of the actively-deforming gouge zones is probably fracture dominated.

    The peninsula segment of the San Andreas Fault (SAF) is forecasted to have the second highest probability of producing a M6.7 or greater earthquake in the San Francisco Bay Area in the next 30 years; yet, relatively little is known about its slip history. In most places, the surface location of the SAF has been determined primarily on the basis of geomorphic features and from mapping surface ruptures associated with the 1906 M7.9 San Francisco earthquake. To more precisely locate traces of this segment of the SAF along the San Francisco peninsula in the subsurface, we acquired a high-resolution seismic imaging survey, using both seismic refraction and reflection profiling, south of Upper Crystal Springs Reservoir near Woodside, California in June 2012. High-resolution seismic images produced from this study may benefit ongoing paleoseismological investigations along the SAF because the seismic data can be used to precisely locate the main fault trace and auxiliary faults that may contribute to the earthquake hazards associated with the fault zone. Furthermore, the seismic images provide insights into near-surface fault structure and P- and S-wave velocities, which can be important in understanding strong shaking resulting from future earthquakes along this segment of the SAF. We acquired both P- and S-wave data using a 60-channel seismograph system connected via cable to 40-Hz vertical-component and 4-Hz horizontal geophones, which were spaced at 1-m intervals along a 60-m-long transect. Seismic sources (shots) were generated by hammer impacts on a steel plate or aluminum block at each geophone location. All shots were recorded on all channels. This survey design permits simultaneous acquisition of reflection and refraction data so that both refraction tomography and reflection images can be developed. Our initial analysis of the P-wave data shows that seismic velocities across the main trace of the SAF vary from about 700 m/s near the surface to more than 2500 m

  13. Mesoscopic structure of cerium waste loaded hydrated cement by SANS

    International Nuclear Information System (INIS)

    Cementation is one of the most commonly used methods for conditioning radioactive wastes. It provides a cost-effective solution for encapsulation of low and intermediate level radioactive wastes into suitable solid form for long term safety storage. Cerium is used for decontamination of alpha contaminated metallic waste and after this decontamination process, secondary wastes with corrosion products are created, which must be managed properly and cemented for near surface disposal. In the present work, modification of mesoscopic structure in hydrated cement due to addition of simulated cerium waste at different concentrations has been investigated by small-angle neutron scattering (SANS). Structural modifications, in mesoscopic length scale, have been observed. The scattering profiles for three kinds of cement blocks (virgin, 10 g/l and 20 g/l of corrosion product (C.P.) with 4 mm thickness) are shown. Data have been analyzed in the light of polydisperse spherical particles model assuming a log-normal distribution. Widely separated bimodal particle size distributions best represent the present data. Further, it has been observed that the scattering profile obeys power-law (Q-n) behaviour in two domains of Q, which reflects the self-similar/self-affined morphology of the inhomogeneities. Estimated parameters from SANS data are tabulated. A comparison is shown mentioning the value of scattering radius of gyration, exponent values (η) and average particle size for each kind of hydrated cement sample. (author)

  14. Solid/complex-fluid interfaces studied by SANS

    International Nuclear Information System (INIS)

    Full text: The study of solid/fluid interfaces by neutron reflectometry is well established, but at present limited to interfaces that can be built onto single crystal silicon or quartz substrates. We have performed SANS experiments on dense slurries of finely ground powders in isotopically substituted complex fluids. With powders 10-30 μm in particle size useful information can be gained from dry powders, and from powders immersed in both microemulsions and emulsions. This information is almost as detailed as we have previously obtained from neutron reflectometry of silicon/emulsion interfaces.1 We will present results from solid glass beads and iron pyrites powder immersed in PIBSA/wet-hexadecane microemulsions and high internal aqueous phase PIBSA/hexadecane emulsions. These show that the surfactant adsorbed at the solid surface can be defined in both footprint and thickness of layer. At the emulsion interfaces, the oil-layer above this surfactant monolayer, previously observed in neutron reflectometry for silicon, is also required to fit this SANS data

In order to mitigate the risk of losing data and improve the availability of data, more and more enterprises are increasingly adopting storage extension technologies to replicate their business critical data to a secondary site. Transmitting this information over distance requires a carrier grade environment with zero data loss, scalable throughput, low jitter, high security and ability to travel long distance. To address this business requirements, there are three basic architectures for storage extension, they are Storage over Internet Protocol, Storage over Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) and Storage over Dense Wavelength Division Multiplexing (DWDM). Each approach varies in functionality, complexity, cost, scalability, security, availability , predictable behavior (bandwidth, jitter, latency) and multiple carrier limitations. Compared with these connectiviy technologies,Coarse Wavelength Division Multiplexing (CWDM) is a Simplified, Low Cost and High Performance connectivity solutions for enterprises to deploy their storage extension. In this paper, we design a storage extension connectivity over CWDM and test it's electrical characteristic and random read and write performance of disk array through the CWDM connectivity, testing result show us that the performance of the connectivity over CWDM is acceptable. Furthermore, we propose three kinds of network architecture of SAN extension based on CWDM interface. Finally the credit-Based flow control mechanism of FC, and the relationship between credits and extension distance is analyzed.

    The Airglow and Solar Spectrometer Instrument (ASSI) on the San Marco D/L satellite has measured solar extreme ultraviolet irradiances. The data are currently being released for analysis. As a preliminary step in evaluating this important dataset, modeled solar irradiances from 4 to 105 nm are presented for comparison to the San Marco data. The comparable flux for March-December 1988 is obtained from a revised and extended empirical solar EUV model derived from OSO 1, OSO 3, OSO 4, OSO 6, AEROS A, and AE-E satellite and six rocket flight datasets. Solar rotational features are prominent on several occasions in the model time series. A useful example is the modeled integrated flux between 30-31 nm which includes the Si XI (30.3-nm) and He II (30.4-nm) irradiance. The modeled flux in this 1-nm range shows both an absolute 22 percent increase from beginning to end of mission and a solar rotational variability with a typical peak-to-valley ratio of 14 percent.

  17. SANS and SAXS study of block copolymer/homopolymer mixtures

    International Nuclear Information System (INIS)

    The lateral and vertical components of the radius of gyration for a single block copolymer chain and those of a single homopolymer chain in the lamellar microdomain space formed by a mixture of diblock copolymers and homopolymers were investigated by means of small-angle neutron scattering (SANS) and the microdomain structures by small-angle X-ray scattering (SAXS). The homopolymers whose molecular weights are much smaller than that of the corresponding chains of the block copolymers were used so that the homopolymers were uniformly solubilized in the corresponding microdomains. The SANS result suggests that the homopolymer chains in the microdomain space as well as the block copolymer chains are more compressed in the direction parallel to the interface and more stretched in the direction perpendicular to the interface than the corresponding unperturbed polymer chains with the same molecular weight. On increasing the volume fraction of the homopolymers the thickness of the lamellar microdomains increases. The block copolymer chains were found to undergo an isochoric affine deformation on addition of the homopolymers or with the change of the thickness of the lamellar microdomains. (orig.)

    2007-06-01

    Full Text Available Blends of styrene-acrylonitrile (SAN with ethylene-propylene-diene (EPDM with and without high impact polystyrene (HIPS as a compatibilizer were studied. One series of blends was prepared in composition 95/5, 90/10, 85/15, 80/20 and 60/40; and the second series of blends was prepared with addition of 5 wt % of HIPS. Their morphology and thermal behaviour were inspected by scanning electronic microscopy (SEM and dynamic mechanic analysis (DMA, respectively. Further on, blends were separated to their components by Soxlet extraction in selective solvent and characterized by Fourier Transform Infrared Spectroscopy (FTIR and gel permeation chromatography (GPC, respectively. The results of morphological observations revealed that the addition of a small percentage of compatibilizer decreases the domain size of the dispersed phase and the compatibility of the blends was enhanced. The shifts of values of glass temperatures (Tg in the examined blends also indicate that with addition of compatibilizer HIPS miscibility between SAN and EPDM is improved.

    1983-10-01

    The US Coast Guard Station, Fort Point is located three-quarters of a nautical mile southeast of the Golden Gate Strait, the entrance to San Francisco Bay. The existing storm wave conditions at Fort Point Station pier make it extremely dangerous for the SAR crews to get on and off the Motor Life Boats at times requiring the vessels to be moored at the San Francisco Yacht Harbor about 1.5 miles east of the Fort Point Station. To mitigate these harsh working conditions the US Coast Guard is considering the feasibility of constructing suitable all-weather moorings for the three Motor Life Boats at the Fort Point Station to enable unimpeded SAR operations, to provide safe working conditions for Coast Guard small boat crews, and to improve small boat maintenance conditions at Fort Point Station. The purpose of this report is to identify, analyze and evaluate physical environmental factors that could affect all-weather moorings siting, configuration and entrance location, as well as potential post construction alterations to littoral conditions and processes. This report includes a description of the site, description of pertinent littoral processes, evaluation of how these processes could affect construction of all-weather moorings, and discussion of design considerations, as well as mitigation measures to minimize potential adverse effects to the physical environment. 19 references, 27 figures, 26 tables.

    Past and future climate data for the San Francisco Bay Area were classified using the Rivas-Martinez (R-M) system to group long-term annual climate averages into categories with biotic significance based on thermotypic and ombrotypic regimes. Bioclimate maps were generated at 270 meter resolution for ten San Francisco Bay Area counties for six 30-year periods from 1911 to 2100 which include the historical 1) 1911-1940, 2) 1941-1970, 3) 1971-2000, and future 4) 2011-2040, 5) 2041-2070, and 6) 2071-2100. Historic averages were generated from PRISM climate data. Future climate projections were generated from two IPCC-based future scenarios (A2 and B1) and two coupled atmosphere-ocean general circulation models (NOAA Geophysical Fluid Dynamics Laboratory and the Parallel Climate Model). Strong congruence was found among the boundaries for historic bioclimates and current vegetation types. However, future scenarios had varying patterns of losses and gains in bioclimate classes and these tracked mesoclimate gradients. Comparisons between projected bioclimatic categories and modeled future climatic water deficit show strong correspondence except in zones of deep alluvial deposits. Maps show areas of bioclimatic stability, e.g. areas that did not change under any future projection, versus areas with significant bioclimatic shifts in all future scenarios. These analyses and maps will be useful for assessing natural resource vulnerability to climate change and natural resource conservation-based climate adaptation decisions.

  17. Coastal Adaptation: The Case of Ocean Beach, San Francisco

    Science.gov (United States)

    Cheong, S.

    2012-12-01

    Coastal erosion, storms, sea-level rise, and tsunamis all lead to inundation that puts people and communities at risk. Adapting to these coastal hazards has gained increasing attention with climate change. Instead of promoting one particular strategy such as seawalls or defending against one type of hazard, scholars and practitioners encourage a combination of existing methods and strategies to promote synergistic effects. The recently published Intergovernmental Panel on Climate Change (IPCC) Special Report on climate extremes reflects this trend in the integration of disaster risk management and climate change adaptation. This paper focuses on the roles, compatibilities, and synergies of three coastal adaptation options - engineering, vegetation, and policy - in the case of Ocean Beach in San Francisco. Traditionally engineering approach and ecosystem conservation often have stood in opposition as hard shoreline structures destroy coastal habitats, worsen coastal erosion, divert ocean currents, and prevent the natural migration of shores. A natural migration of shores without structure translates into the abandonment of properties in the coastal zone, and is at odds with property rights and development. For example, policies of relocation, retreat, and insurance may not be popular given the concerns of infrastructure and coastal access. As such, engineering, natural defense, and policy can be more conflictual than complementary. Nonetheless, all these responses are used in combination in many locations. Complementarities and compatibilities, therefore, must be assessed when considering the necessity of engineering responses, natural defense capabilities, and policy options. In this light, the question is how to resolve the problem of mixed responses and short- and long-term interests and values, identify compatibilities, and generate synergies. In the case of Ocean Beach, recent erosions that endangered San Francisco's wastewater treatment system acted as major

  18. Fog and Haze in California's San Joaquin Valley

    Science.gov (United States)

    2001-01-01

    This illustration features images of southern California and southwestern Nevada acquired on January 3, 2001 (Terra orbit 5569), and includes data from three of MISR's nine cameras. The San Joaquin Valley, which comprises the southern extent of California's Central Valley, covers much of the viewed area. Also visible are several of the Channel Islands near the bottom, and Mono and Walker Lakes, which stand out as darker patches near the top center, especially in the vertical and backward oblique images. Near the lower right of each image is the Los Angeles Basin, with the distinctive chevron shape of the Mojave Desert to its north.The Central Valley is a well-irrigated and richly productive agricultural area situated between the Coast Range and the snow-capped Sierra Nevadas. During the winter, the region is noted for its hazy overcasts and a low, thick ground fog known as the Tule. Owing to the effects of the atmosphere on reflected sunlight, dramatic differences in the MISR images are apparent as the angle of view changes. An area of thick, white fog in the San Joaquin Valley is visible in all three of the images. However, the pervasive haze that fills most of the valley is only slightly visible in the vertical view. At the oblique angles, the haze is highly distinguishable against the land surface background, particularly in the forward-viewing direction. Just above image center, the forward view also reveals bluish-tinged plumes near Lava Butte in Sequoia National Forest, where the National Interagency Coordination Center reported an active forest fire.The changing surface visibility in the multi-angle data allows us to derive the amount of atmospheric haze. In the lower right quadrant is a map of haze amount determined from automated processing of the MISR imagery. Low amounts of haze are shown in blue, and a variation in hue through shades of green, yellow, and red indicates progressively larger amounts of airborne particulates. Due to the topographically

    Surface water quality in urban settings can become contaminated by anthropogenic inputs. Yosemite Creek watershed is situated on the east side of San Francisco near Bayview Hunters Point and provides an ideal location for water quality investigations in urban environments. Accordingly, students from Philip and Sala Burton High School monitored water quality at three locations for their physicochemical and biological characteristics. Water was tested for pH, dissolved oxygen, conductivity, total dissolved solids, salinity, and oxidation reduction potential. In addition, a Hach DR 850 digital colorimeter was utilized to measure chlorine, fluorine, nitrogen, phosphorous, and sulfate. The biological component was assessed via monitoring benthic macro invertebrates. Specifically, the presence of caddisfly (Trichoptera) were used to indicate low levels of contaminants and good water quality. Our results indicate that water quality and macro invertebrate populations varied spatially within the watershed. Further investigation is needed to pinpoint the precise location of contaminant inputs.

    Ortega, H B; Borchardt, K A; Hamilton, R; Ortega, P; Mahood, J

    1984-01-01

    The prevalence of enteric protozoa was studied in a survey conducted among 150 male homosexual patients in San Francisco. All patients were from a private practice in internal medicine. Each was asked to complete a questionnaire and to submit multiple stool specimens for examination. Of this group, 47% were positive for one or more potentially pathogenic intestinal protozoa; Entamoeba histolytica was found in 36%, Entamoeba hartmanni in 35%, Giardia lamblia in 5%, and Dientamoeba fragilis in 1.3%. Symptoms were unreliable as a diagnostic index of intestinal protozoan infection. Colonization rates could not be correlated with any specific sexual technique. The large number of homosexuals at risk, combined with the potential for difficulties in diagnosis and contact-tracing, indicate the possibility that enteric pathogenic protozoa will cause future health problems in this population.

    The volcano Chichontepeque (San Vicente) is one of the nine recent volcanoes making up the El Salvador sector of the WNW-ESE-trending active Central American volcanic belt. Thermal activity is at present reduced to a few thermal springs and fumaroles. The most important manifestations (Agua Agria and Los Infernillos Ciegos) are boiling springs and fumaroles located on the northern slope of the volcano (850 m a.s.l.) along two radial faults. The application of geothermometric and geobarometric methods to the gases and thermal waters suggests that both thermal areas are linked to the identified 1100-1300 m reservoir, whose temperature (250{sup o}C), lateral extension and chemical composition, as resulting from this study, are of interest for industrial development.

The red continuum maps show the photometric contrast of solar features in the photosphere while the Ca II K-line maps show the same in the lower chromosphere. Comparing these maps with each other, and with those of other solar groups, will yield information regarding the evolutionary patterns of solar activity at different heights of the solar atmosphere. This is a first step toward a comprehensive set of synoptic maps covering the period from mid-solar cycle 22 in 1988 to the present. This work has been supported in part by NSF grant ATM-0848518.

    Full Text Available The san antonio breast cancer syposium (SABCS 2014 was an exciting one this year. Data from the SOFT trial was presented that had potential implications on the treatment of pre menapausal women with hormone receptor positive breast cancer. In a phase II trial fulvestrant was found to significantly improve progression free and overall survival compared to anastrazole in the first line treatment of women with hormone receptor positive metastatic breast cancer. We saw a number of intersting abstracts looking at trying to refine the role of platinums and exploring the role of blocking PD-1 among women with triple receptor negative breast cancer. We also saw the results of a number of trials trying to refine standard chemotherapeutic regimens. Here we will review some fon the most interesting abstracts presented this year at SABCS 2014.

  11. Critical crossover phenomena in compatible polymer blends studied with SANS

    Polymer blends show a much larger 3d-Ising regime, e.g. a much larger Ginzburg number Gi than predicted by the Ginzburg criterion. This discrepancy is supposed to be explained by the compressibility or the free volume of the blend. In this paper we present and discuss the Gi number of polymer...... monomeric microstructure and on pressure. This clearly shows that Gi is not a universal function. The observed strong decrease of Gi with pressure is a clear experimental proof that the critical crossover behaviour in polymer blends is indeed strongly influenced by the compressibility or free volume of the...... blends, different in chemistry, molecular weight, and microstructure. One sample was also studied at a different pressure. Gi was determined by describing the susceptibility obtained from SANS with the crossover function from Belyakov et al. The essential results are that Gi depends sensitively on...

    Despite widespread detection of microplastic pollution in marine environments, data describing microplastic abundance in urban estuaries and microplastic discharge via treated municipal wastewater are limited. This study presents information on abundance, distribution, and composition of microplastic at nine sites in San Francisco Bay, California, USA. Also presented are characterizations of microplastic in final effluent from eight wastewater treatment plants, employing varying treatment technologies, that discharge to the Bay. With an average microplastic abundance of 700,000particles/km(2), Bay surface water appears to have higher microplastic levels than other urban waterbodies sampled in North America. Moreover, treated wastewater from facilities that discharge into the Bay contains considerable microplastic contamination. Facilities employing tertiary filtration did not show lower levels of contamination than those using secondary treatment. As textile-derived fibers were more abundant in wastewater, higher levels of fragments in surface water suggest additional pathways of microplastic pollution, such as stormwater runoff.

    Concentrations of many anthropogenic contaminants in the San Francisco Estuary exist at levels that have been associated with biological effects elsewhere, so there is a potential for them to cause biological effects in the Estuary. The purpose of this paper is to summarize information about biological effects on the Estuary's plankton, benthos, fish, birds, and mammals, gathered since the early 1990s, focusing on key accomplishments. These studies have been conducted at all levels of biological organization (sub-cellular through communities), but have included only a small fraction of the organisms and contaminants of concern in the region. The studies summarized provide a body of evidence that some contaminants are causing biological impacts in some biological resources in the Estuary. However, no general patterns of effects were apparent in space and time, and no single contaminant was consistently related to effects among the biota considered. These conclusions reflect the difficulty in demonstrating biological effects due specifically to contamination because there is a wide range of sensitivity to contaminants among the Estuary's many organisms. Additionally, the spatial and temporal distribution of contamination in the Estuary is highly variable, and levels of contamination covary with other environmental factors, such as freshwater inflow or sediment-type. Federal and State regulatory agencies desire to develop biological criteria to protect the Estuary's biological resources. Future studies of biological effects in San Francisco Estuary should focus on the development of meaningful indicators of biological effects, and on key organism and contaminants of concern in long-term, multifaceted studies that include laboratory and field experiments to determine cause and effect to adequately inform management and regulatory decisions. ?? 2006 Elsevier Inc.

  16. Characterization of the Drosophila ortholog of the human Usher Syndrome type 1G protein sans.

    Directory of Open Access Journals (Sweden)

    Fabio Demontis

    Full Text Available BACKGROUND: The Usher syndrome (USH is the most frequent deaf-blindness hereditary disease in humans. Deafness is attributed to the disorganization of stereocilia in the inner ear. USH1, the most severe subtype, is associated with mutations in genes encoding myosin VIIa, harmonin, cadherin 23, protocadherin 15, and sans. Myosin VIIa, harmonin, cadherin 23, and protocadherin 15 physically interact in vitro and localize to stereocilia tips in vivo, indicating that they form functional complexes. Sans, in contrast, localizes to vesicle-like structures beneath the apical membrane of stereocilia-displaying hair cells. How mutations in sans result in deafness and blindness is not well understood. Orthologs of myosin VIIa and protocadherin 15 have been identified in Drosophila melanogaster and their genetic analysis has identified essential roles in auditory perception and microvilli morphogenesis, respectively. PRINCIPAL FINDINGS: Here, we have identified and characterized the Drosophila ortholog of human sans. Drosophila Sans is expressed in tubular organs of the embryo, in lens-secreting cone cells of the adult eye, and in microvilli-displaying follicle cells during oogenesis. Sans mutants are viable, fertile, and mutant follicle cells appear to form microvilli, indicating that Sans is dispensable for fly development and microvilli morphogenesis in the follicle epithelium. In follicle cells, Sans protein localizes, similar to its vertebrate ortholog, to intracellular punctate structures, which we have identified as early endosomes associated with the syntaxin Avalanche. CONCLUSIONS: Our work is consistent with an evolutionary conserved function of Sans in vesicle trafficking. Furthermore it provides a significant basis for further understanding of the role of this Usher syndrome ortholog in development and disease.

  17. Tectonic history of the north portion of the San Andreas fault system, California, inferred from gravity and magnetic anomalies

    Geologic and geophysical data for the San Andreas fault system north of San Francisco suggest that the eastern boundary of the Pacific plate migrated eastward from its presumed original position at the base of the continental slope to its present position along the San Andreas transform fault by means of a series of eastward jumps of the Mendocino triple junction. These eastward jumps total a distance of about 150 km since 29 Ma. Correlation of right-laterally displaced gravity and magnetic anomalies that now have components at San Francisco and on the shelf north of Point Arena indicates that the presently active strand of the San Andreas fault north of the San Francisco peninsula formed recently at about 5 Ma when the triple junction jumped eastward a minimum of 100 km to its present location at the north end of the San Andreas fault. -from Authors

    As of the time of this writing, the San Francisco Bay region is home to about 6.8 million people, ranking fifth among population centers in the United States. Most of these people live on the coastal lands along San Francisco Bay, the Sacramento River delta, and the Pacific coast. The region straddles the tectonic boundary between the Pacific and North American Plates and is crossed by several strands of the San Andreas Fault system. These faults, which are stressed by about 4 cm of relative plate motion each year, pose an obvious seismic hazard.
