The Cuenca de Oro, a Pull-Apart Basin Hosting Precious Metal Deposits Along the Re- Activated Seri-Tahue Terrane Boundary  

NASA Astrophysics Data System (ADS)

At the intersection of Chihuahua, Sonora, and Sinaloa a boundary between the Seri and Tahue terranes has been hypothesized, and further refined as the Sinforosa Lineament. Near the western termination of the Sinforosa Lineament lies a topographic basin. Part of this study will be to better define this pull-apart basin, informally named the Cuenca de Oro due to its numerous precious metal deposits. The intention of this study is to test that the Seri-Tahue terrane boundary was re-energized during the beginning of extension related to the opening of the Sea of Cortez (~30ma). It is probable that the precious metal occurrences are related to the initiation of extension(alunite at El Sauzal has been dated at ~30ma). Five field excursions totaling sixty days of field work have been completed and a first draft of a regional geologic map has been made. Large shear zones support the hypothesis of a pull-apart basin. A study of the alteration and lineament intersections determine the location of many known precious metal deposits. By creating multiple cross-sections the basin can be modeled in three dimensions and a tectonic history can be interpreted. This study will present a structural analysis of the Cuenca de Oro and develop a tectonic history related temporally with the epithermal mineralization events.

Reconexin magntica en una regin activa en decaimiento  

NASA Astrophysics Data System (ADS)

Se han obtenido observaciones desde Tierra (H? y magnetogramas) coordinadas con el Soft X-ray Telescope (SXT), a bordo del satlite japons Yohkoh, de una regin activa bipolar en decaimiento. Estos datos constituyen la base para el estudio de un punto brillante en rayos X (PBX) y de la actividad relacionada con el mismo en distintas capas de la atmsfera solar. Las observaciones muestran que el PBX est relacionado con la aparicin de un bipolo menor (~ 1020 Mx) y que su abrillantamiento continuo, as como sus aumentos de brillo espordicos (``fulguraciones"), son el resultado de la reconexin entre el pequeo arco emergente (visto en H? como un sistema de filamentos arqueados, SFA) y arcos mayores asociados al campo facular preexistente. Se ha extrapolado el campo magntico observado en la aproximacin libre de fuerzas lineal y se ha seguido su evolucin a lo largo de la vida del PBX. Se ha calculado la posicin de las cuasiseparatrices (CSs) a partir del campo modelado. Las lneas de campo extrapoladas, cuyas bases fotosfricas se encuentran a ambos lados de las CSs, estn de acuerdo con las estructuras cromosfricas y coronales observadas. Se ha calculado el espesor de la CD ubicada a lo largo de la polaridad negativa emergente, encontrndose que su variacin est de acuerdo con la evolucin de la intensidad del PBX; la CS es muy delgada durante la vida del PBX (~ 100 m), mientras que su espesor aumenta considerablemente (>= 10^4 m) cuando el PBX desaparece de las imgenes del SXT. Estos resultados sealan que el abrillantamiento y las ``fulguraciones" de este PBX se deben al proceso de reconexin en 3D que tiene lugar en las CSs.

Observaciones del disco solar y de una protuberancia quiescente en radiacin ultravioleta

Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propsito es investigar las velocidades macroscpicas de varias especies metlicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una tcnica mixta para modelar la distribucin de estructuras en UV en el Sol quieto. Las velocidades macroscpicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada lnea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscpicas entre 5 y 40 km/seg. Tambin detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

Genetic relationships among Mayaro and Una viruses suggest distinct patterns of transmission.  

PubMed

Mayaro and Una viruses (MAYV, UNAV) are mosquito-borne alphaviruses that may cause an acute febrile illness characterized by headache, retro-orbital pain, and rash that may progress to a severe and prolonged arthralgia. MAYV was first isolated in Trinidad in 1954, and UNAV was first identified in northern Brazil in 1959. Since then, numerous isolates of these agents have been made from humans, wild vertebrates, and mosquitoes in several countries in northern South America. Serological evidence suggests that these viruses are also present in portions of Central America. Because little is known about the natural transmission cycle of MAYV and virtually nothing is known about UNAV transmission, 63 isolates covering the known geographic and temporal ranges were used in phylogenetic analyses to aid in understanding the molecular epidemiology. Approximately 2 kb from the E1 and E2 glycoprotein genes and the complete 3' non-coding region were sequenced. Phylogenetic analyses of these sequences indicated that two distinct genotypes of MAYV exist with a distinct clade consisting exclusively of UNAV (previously designated as a subtype of MAYV). One MAYV genotype (genotype D) contains isolates from Trinidad and the northcentral portion of South America including Peru, French Guiana, Surinam, Brazil, and Bolivia. All of these isolates are highly conserved with a nucleotide divergence of < 6%. The second MAYV genotype (genotype L) contains isolates only from Brazil that are highly conserved (< 4% nucleotide divergence) but are quite distinct (15-19%) from the first genotype isolates. These analyses provide possible explanations for the natural ecology and transmission of MAYV and UNAV. PMID:16968922

S?ndrome del Outlet Tor?cico: ?Una Patolog?a Siempre Quir?rgica? An?lisis de una Serie de 31 Cirug?as Realizadas por V?a Supraclavicular Serie cl?nica

Introduccin: El sndrome de outlet torcico es una compresin del plexo braquial que suscita polmica. Se clasifica en Outlet Torcico Verdadero o neurognico (OTV) y Outlet Torcico Disputado o no neurognico (OTD). El primero presenta sntomas motores en la mano, mientras que el segundo slo sntomas sensitivos en el miembro superior. El objetivo de este trabajo es analizar los resultados obtenidos en una serie de 31 cirugas. Mtodos: Se analizaron las cirugas de nervios efectuadas entre 2003-2012, tomando los diagnsticos de outlet torcico cuyo perodo de seguimiento post-operatorio mnimo fuera de 6 meses. Se buscaron los siguientes datos: edad, sexo, presencia de sntomas sensitivos y/o motores, clasificacin, resultado de los estudios neurofisiolgicos y de imgenes, resultado de la ciruga, complicaciones post-operatorias y recidivas. Resultados: Se incluyeron 31 cirugas realizadas en 30 pacientes, 9 OTV (8 mujeres) de 24.3 aos, y 21 con OTD (18 mujeres) de 37.4 aos de edad en promedio. Un 90% presentaron alteraciones neurofisiolgicas preoperatorias, y 66,6% imagenolgicas. En el intraoperatorio, el 100% de los OTV present una alteracin anatmica relacionada con la sintomatologa, hecho observado slo en el 36.7% de los OTD operados. El 87,5% de los OTV mejoraron sensitivamente, mientras que 77,7% mejoraron la atrofia. Por el contrario, 45.4% de los OTD mejoraron permanentemente, 36.3% no tuvieron cambios, 13.6% mejoraron transitoriamente y 4.5% (un caso) empeor. Las complicaciones post-operatorias fueron ms frecuentes aunque transitorias en el grupo de OTV (3 casos sobre 9 operados, 33.3%) que en los OTD (3 casos sobre 22, un 13.6%). Conclusin: El OTV suele mayormente mejorar luego de la ciruga, igual que el OTD aunque en una proporcin mucho menor. Estos hallazgos coinciden con otros reportes recientes de esta patologa.

Anthropization on the Cerrado biome in the Brazilian Uruu-Una Ecological Station estimated from orbital images.  

PubMed

In this study we analysed the dynamics of deforestation and burnings during the dry seasons from 2003 to 2008 in the Uruu-Una Ecological Station (UUES) and its buffer zone, located in the Cerrado biome of the southwest of Piau, a Brazil's State, based on images from the orbital sensors CCD/CBERS-2 and TM/Landsat-5. Two dates from each of the years were interpreted and analysed: one in the middle of the dry season and one at the end. The deforested areas were expanded through the period analysed and were larger in the buffer zone, suggesting a relative protection of the UUES. New cut-offs were predictable because of the early opening of roads that would become their limits. The burning scars were larger at the end of the dry season as a consequence of the management and implementation of agricultures and pastures. In 2004 and 2007 these scars were larger probably because of the increase of dry phytomass that every three years is big enough to spread the fire originated in the anthropogenic burnings through the native vegetation. This scenario reaffirms the need for: stronger enforcement in order to stop anthropisation in the UUES and a management plan, absent for this unit so far. These proceedings are urgent also because the UUES is located in one of the most preserved regions of the Cerrado and controversially where intense anthropisation in ongoing, which stresses the lack, need and urgency of biological conservation proceedings for the Piau's southeastern Cerrado.

Inverse modeling of groundwater flow in the semiarid evaporitic closed basin of Los Monegros, Spain  

NASA Astrophysics Data System (ADS)

Only minor attention has been given in the past to the study of closed-basin hydrogeology in evaporitic environments, because these basins usually contain poor-quality groundwater. The motivation for hydrogeological research in the Los Monegros area in northeastern Spain was the approval in 1986 of a large irrigation project in the Ebre River basin. The irrigation of 60,000 ha is planned, partly in an evaporitic closed basin containing playa lakes. The project has given rise to environmental concerns. The evaluation of the hydrologic impacts of irrigation requires quantifying properly the hydrogeology of the area. With the available information, a conceptual hydrogeological model was formulated that identifies two main aquifers connected through a leaky aquitard. On the basis of the conceptual model, a numerical model was calibrated under steady-state conditions using the method of maximum-likelihood automatic parameter estimation (Carrera and Neuman, 1986a). The calibrated model reproduces the measured hydraulic heads fairly well and is consistent with independent information on groundwater discharge. By the solution of the inverse problem, reliable parameter estimates were obtained. It is concluded that anisotropy plays a major role in some parts of the lower aquifer. The geometric average of model conductivity is almost two orders of magnitude larger than the average conductivity derived from small-scale field tests. This scale effect in hydraulic conductivity is consistent with the findings of Neuman (1994) and Snchez-Vila et al. (1996). Rsum Dans le pass, on s'est peu intress l'hydrogologie des bassins ferms en milieu vaporitique, parce que ces bassins possdent en gnral de l'eau souterraine de qualit mdiocre. L'intrt port aux recherches hydrogologiques dans la rgion de Los Monegros, dans le nord-est de l'Espagne est d l'approbation en 1986 d'un vaste projet d'irrigation dans le bassin de l'Ebre. L'irrigation de 60000 ha a t programme, en partie dans un bassin vaporitique ferm o existent des lacs de playa. Le projet a fait merg des proccupations environnementales. L'valuation des impacts hydrologiques de l'irrigation implique de quantifier correctement l'hydrogologie de cette rgion. A partir des informations disponibles, un modle hydrogologique conceptuel a ttabli il identifie deux aquifres principaux interconnects par drainance au travers d'un impermable. Un modle numrique, tabli sur la base de ce modle conceptuel, a t calibr en conditions de rgime permanent, en utilisant la mthode d'estimation automatique du maximum de vraisemblance des paramtres (Carrera and Neuman, 1986a). Le modle calibr reproduit correctement la pizomtrie mesure et est en accord avec les informations concernant l'coulement des nappes. La rsolution du problme inverse a fourni des estimations acceptables des paramtres. On en a conclu que l'anisotropie joue un rle essentiel dans certaines parties de l'aquifre infrieur. La moyenne gomtrique de la conductivit hydraulique est d'environ deux ordres de grandeur plus leve que la conductivit hydraulique moyenne obtenue par des essais de terrain l'chelle locale. Cet effet d'chelle sur la conductivit hydraulique est conforme aux rsultats obtenus par Neuman (1994) et Snchez-Vila et al. (1996). Resumen La hidrogeologa de zonas endorreicas en zonas evaporticas ha recibido muy poca atencin en el pasado debido fundamentalmente a que en estas zonas las aguas subterrneas tienen una elevada salinidad debido a la alta solubilidad de sus materiales. El inters por la hidrogeologa de la zona de Los Monegros en el noreste de Espaa surgi a raiz de la aprobacin en 1986 del proyecto de Los Monegros II en la zona central del valle del Ebro que contempla la puesta en regado de 60,000 ha, algunas de las cuales se encuentran situadas en la zona endorreica de Los Monegros en la que existen toda una serie de lagunas salinas.

Estudio epidemiol?gico de sucesos traum?ticos, trastorno de estr?s post-traum?tico y otros trastornos psiqui?tricos en una muestra representativa de Chile  

PubMed Central

RESUMEN Durante la dcada de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estrs post-traumtico (TEPT) evolucion de estudios especficos en un principio, sobre veteranos de guerra y sobre vctimas de desastres, a estudios epidemiolgicos ms tarde, sin embargo, la epidemiologa del TEPT en pases en desarrollo ha sido un rea poco estudiada hasta ahora. Los expertos en el rea de trauma han propuesto que los sucesos traumticos que ocurren en la niez son ms perjudiciales para la salud mental que aquellos que ocurren ms tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiolgico llevado a cabo en Chile. Especficamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados ms frecuentemente con l, as como la comorbilidad de este trastorno con otros trastornos psiquitricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, as como la exposicin a traumas en una muestra representativa de chilenos. Adems se compar la prevalencia de trastornos psiquitricos en personas que sufrieron su primer trauma durante la niez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiolgicos se usaron mdulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagnstica siguiendo los criterios del DSM-III-R (DISIII-R). Para evaluar el resto de los trastornos psiquitricos se us la Entrevista Diagnstica Internacional Compuesta (CIDI). Estos instrumentos fueron administrados en tres ciudades chilenas a 2390 personas mayores de 15 aos. Para estimar los errores estndares (EE) debido al diseo de la muestra y a la necesidad de ajuste se us el mtodo Taylor de linearizacin seriada. Tambin se us un anlisis de regresin logstica para examinar la relacin entre el TEPT, los factores demogrficos de riesgo y el tipo de trauma. Adems se utiliz la regresin logstica multivariada para evaluar si la relacin entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, as como para calcular las tasas y la oportunidad relativa (razn de productos cruzados) de trastornos psiquitricos a lo largo de la vida. El primer anlisis arroj que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traumticos reportados, la violacin sexual tuvo una correlacin ms alta con el TEPT que los dems hechos traumticos. Las mujeres tuvieron ms probabilidades de experimentar TEPT que los hombres, despus de controlar la variable asalto violento. El segundo anlisis evidenci que los que haban sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiquitrico en comparacin con aquellos que no reportaron traumas. Tambin se encontr que los que sufrieron su primer trauma durante la infancia tuvieron ms probabilidad de desarrollar trastornos de pnico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del nmero de traumas que sufrieron y de las diferencias demogrficas. Aunque Chile tiene un contexto histrico-cultural y una economa diferente a otros pases en los que se ha estudiado anteriormente la epidemiologa del TEPT, el presente estudio reflej tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes pases. Tambin estos resultados sugieren que los sucesos traumticos en la infancia

Evolutionary Medicine is an emergent basic science that offers new and varied perspectives to the comprehension of human health. The application of classic evolutionary theories (descent with modification, and natural selection) to the human organism, to its pathogens, and their mutual co-evolution, provides new explanations about why we get sick, how we can prevent this, and how we can heal.

C/1999 S4 (LINEAR): la morte di una cometa  

NASA Astrophysics Data System (ADS)

The comet C/1999 S4 was expected to be a moderately bright object during summer 2000. It was observed by visual, photographic and CCD techniques. The derived light curve shows that the comet reached a brightness maximum (mag. 6 around July 26) corresponding to the total dissolution of its nucleus. From the analysis of the light curve a double maximum was detected, the dissolution event appearing to start around July 20. Several morphological changes were also observed during the apparition in relation to partial fragmentation events. The comet aspect completely changed during the final disruption. Relevant changes in the plasma tail were observed and they are probably related both to the activity of the nucleus and to the solar wind. A perspective anti-tail was detected in early July.

Groundwater demand management at local scale in rural areas of India: a strategy to ensure water well sustainability based on aquifer diffusivity and community participation  

NASA Astrophysics Data System (ADS)

Watershed development programmes provide an opportunity for sustainable management strategies, although currently, they remain largely `supply-side' mechanisms of water resources development. Hydrogeological conditions, community participation and status of groundwater usage are important in evolving strategies on `demand-side' groundwater management. Neemkheda aquifer is a typical low-storage, low-hydraulic conductivity aquifer from a watershed in the dryland regions of Madhya Pradesh State of central India. A shallow unconfined aquifer, it consists of an upper coarse, calcareous sandstone unit underlain by a fine-grained sandstone unit. A `well commune' of seven wells is poised to test the concept of joint groundwater management, wherein wells are mechanisms of tapping a common water source, the Neemkheda aquifer. The strategy for systematic groundwater management in the Neemkheda well commune is based upon the relationship between Transmissivity (T) and Storage coefficient (S), i.e. aquifer diffusivity, and its variation within the aquifer. Wells within a high diffusivity domain tend to dewater more quickly than wells within a low diffusivity domain. A well-use schedule during the dry season, based upon aquifer diffusivity forms the basis of the groundwater management concept. The distribution of local aquifer diffusivities governs the relationship between local and regional aquifer depletion times and forms the basis of the groundwater management exercise being proposed for the Neemkheda aquifer. Los programas de desarrollo de una cuenca hdrica son una oportunidad para el uso de estrategias de gestin sostenible, aunque hoy en da estas siguen siendo principalmente mecanismos para el desarrollo de recursos hdricos con nfasis en la ``oferta''. Las condiciones hidrogeolgicas, la participacin comunitaria y la condicin de utilizacin del agua subterrnea, son importantes en el desarrollo de estrategias para la gestin del agua subterrnea, desde el punto de vista de la ``demanda''. El acufero de Neemkheda es un acufero tpico de almacenamiento bajo y conductividad hidrulica baja, perteneciente a una cuenca hdrica ubicada en las regiones secas del Estado de Madhya Pradesh, en la parte central de India. Un acufero de tipo libre, somero, formado por una unidad superior de arenisca calcrea de grano grueso, subyacida por una unidad de arenisca de grano fino. Un campo de pozos comunitario compuesto por siete pozos, pone a prueba el concepto de gestin conjunta del agua subterrnea, dentro del cual los pozos son mecanismos para usar una fuente de agua comn: El acufero de Neemkheda. La estrategia usada para la gestin sistemtica del agua subterrnea, en el campo de pozos comunitario de Neemkheda, se basa en la relacin existente entre Transmisividad (T) y Coeficiente de Almacenamiento (S), es decir en la Difusividad del Acufero y en su variacin observada dentro del mismo acufero. Los pozos cuya difusividad esta dentro de un rango alto, tienden a experimentar un descenso en su nivel mas rpidamente que aquellos pozos con una difusividad baja. El concepto de gestin de agua subterrnea se basa en un programa especial de operacin para cada pozo durante la estacin seca, el cual a su vez se basa en la difusividad del acufero. La distribucin de difusividades locales del acufero rige las relaciones entre las pocas de descensos de nivel en el acufero a escala regional y local, y adems constituyen la base del ejercicio de la gestin del agua subterrnea que se esta proponiendo para el acufero de Neemkheda. Les programmes de dveloppement des bassins versants offrent une occasion de dvelopper des stratgies pour une gestion durable, bien qu' prsent elles restent en grande mesure `le terme source' dans le mcanisme de dveloppement de la ressource en eau.

A thick lens of fresh groundwater in the southern Lihue Basin, Kauai, Hawaii, USA  

NASA Astrophysics Data System (ADS)

A thick lens of fresh groundwater exists in a large region of low permeability in the southern Lihue Basin, Kauai, Hawaii, USA. The conventional conceptual model for groundwater occurrence in Hawaii and other shield-volcano islands does not account for such a thick freshwater lens. In the conventional conceptual model, the lava-flow accumulations of which most shield volcanoes are built form large regions of relatively high permeability and thin freshwater lenses. In the southern Lihue Basin, basin-filling lavas and sediments form a large region of low regional hydraulic conductivity, which, in the moist climate of the basin, is saturated nearly to the land surface and water tables are hundreds of meters above sea level within a few kilometers from the coast. Such high water levels in shield-volcano islands were previously thought to exist only under perched or dike-impounded conditions, but in the southern Lihue Basin, high water levels exist in an apparently dike-free, fully saturated aquifer. A new conceptual model of groundwater occurrence in shield-volcano islands is needed to explain conditions in the southern Lihue Basin. Rsum. Dans le sud du bassin de Lihue (Kauai, Hawaii, USA), il existe une paisse lentille d'eau souterraine douce dans une vaste rgion faible permabilit. Le modle conceptuel conventionnel pour la prsence d'eau souterraine Hawaii et dans les autres les de volcans en bouclier ne rend pas compte d'une lentille d'eau douce si paisse. Dans ce modle conceptuel, les accumulations de lave dont sont forms la plupart des volcans en bouclier couvrent de vastes rgions relativement forte permabilit, avec des lentilles d'eau douce peu paisses. Dans le sud du bassin de Lihue, les laves remplissant le bassin et les sdiments constituent une rgion tendue faible conductivit hydraulique rgionale, qui, sous le climat humide du bassin, est sature presque jusqu' sa surface; les surfaces pizomtriques sont plusieurs centaines de mtres au-dessus du niveau de la mer quelques kilomtres de la cte. On pensait jusqu' prsent que des niveaux pizomtriques aussi levs dans des les de volcans en bouclier n'existaient que dans le cas de nappes perches ou de blocage par un dyke, mais dans le sud du bassin de Lihue, des niveaux pizomtriques levs existent dans un aquifre apparemment sans dyke et compltement satur. Un nouveau modle conceptuel de prsence d'eau souterraine dans les les de volcans en bouclier est ncessaire pour expliquer les conditions observes dans le sud du bassin de Lihue. Resumen. Se ha determinado la existencia de un espeso lentejn de aguas subterrneas dulces en una extensa regin de baja permeabilidad situada al sur de la cuenca de Lihue, en Kauai (Hawaii, Estados Unidos de Amrica). El modelo conceptual convencional de las aguas subterrneas en Hawai y en otros cinturones de islas volcnicas no considera la existencia de lentejones tan gruesos de agua dulce. En dicho modelo, las acumulaciones de flujos de lava que constituyen la mayora de los cinturones volcnicos se desarrollan en grandes reas de permeabilidad relativamente baja y con pequeos lentejones de agua dulce. En el sur de la cuenca de Lihue, las lavas de relleno y los sedimentos forman una regin extensa de baja conductividad hidrulica regional que, con el clima hmedo de la zona, est saturada hasta prcticamente la superficie del terreno, mientras que el nivel fretico se encuentra centenares de metros por encima del nivel del mar a pocos kilmetros de la lnea de costa. Se crea hasta ahora que, en los cinturones de islas volcnicas, tales niveles slo tenan lugar en acuferos colgados o en condiciones de confinamiento por diques, pero, al sur de la cuenca de Lihue, se dan en acuferos completamente saturados que no estn limitados por diques. Se necesita un nuevo modelo conceptual de las aguas subterrneas en cinturones de islas volcnicas para explicar las condiciones halladas en la cuenca meridional de Lihue.

SOBRE LA NICA POBLACIN CONOCIDA DEL JIRFIDO MITILANOTHERIUM (GIRAFFIDAE, ARTIODACTYLA, MAMMALIA) EN EL PLIOCENO SUPERIOR TERMINAL DE EUROPA OCCIDENTAL (FONELAS P-1, CUENCA DE GUADIX, GRANADA) NOTES ON THE ONLY KNOWN POPULATION OF THE GIRAFFID MITILANOTHERIUM (GIRAFFIDAE, ARTIODACTYLA, MAMMALIA) FROM THE LATE UPPER PLIOCENE OF WESTERN EUROPE (FONELAS P-1, GUADIX BASIN, GRANADA)

This work describes the first fossils representing the genus Mitilanotherium discovered in Western Europe. The large size and the patent gracefulness of these Granadine giraffes suggest they belong to a different species to that recorded for Eastern Europe, Mitilanotherium martinii. This hypothesis may soon be tested using new materials recently found at the Fonelas P-1 site (MNQ18 zone).

Climate change impacts on groundwater resources: modelled deficits in a chalky aquifer, Geer basin, Belgium  

NASA Astrophysics Data System (ADS)

An integrated hydrological model (MOHISE) was developed in order to study the impact of climate change on the hydrological cycle in representative water basins in Belgium. This model considers most hydrological processes in a physically consistent way, more particularly groundwater flows which are modelled using a spatially distributed, finite-element approach. Thanks to this accurate numerical tool, after detailed calibration and validation, quantitative interpretations can be drawn from the groundwater model results. Considering IPCC climate change scenarios, the integrated approach was applied to evaluate the impact of climate change on the water cycle in the Geer basin in Belgium. The groundwater model is described in detail, and results are discussed in terms of climate change impact on the evolution of groundwater levels and groundwater reserves. From the modelling application on the Geer basin, it appears that, on a pluri-annual basis, most tested scenarios predict a decrease in groundwater levels and reserves in relation to variations in climatic conditions. However, for this aquifer, the tested scenarios show no enhancement of the seasonal changes in groundwater levels. Un modle hydrologique intgr (MOHISE) a t dvelopp afin d'tudier l'impact du changement climatique sur le cycle hydrologique de bassins versants reprsentatifs de Belgique. Ce modle prend en compte tous les processus hydrologiques d'une manire physiquement consistante, plus particulirement les coulements souterrains qui sont modliss par une approche spatialement distribue aux lments finis. Grce cet outil numrique prcis, aprs une calibration et une validation dtailles, des interprtations quantitatives peuvent tre ralises partir des rsultats du modle de nappe. Considrant des scnarios de changements climatiques de l'IPCC, l'approche intgre a t applique pour valuer l'impact du changement climatique sur le cycle de l'eau du bassin du Geer en Belgique. Le modle de nappe est dcrit en dtail et les rsultats sont discuts en terme d'impact du changement climatique sur l'volution des rserves souterraines. Les premiers rsultats indiquent que des dficits d'eau souterraine peuvent apparatre dans le futur en Belgique. Se ha desarrollado un modelo hidrolgico integrado (MOHISE) para estudiar el impacto del cambio climtico en el ciclo hidrolgico de cuencas representativas en Blgica. Este modelo considera todos los procesos hidrolgicos de forma coherente, especialmente en relacin con los flujos de aguas subterrneas, que son modelados por medio de un enfoque de elementos finitos espacialmente distribuidos. Gracias a esta herramienta numrica precisa, y tras una calibracin y validacin detalladas, se puede obtener interpretaciones cuantitativas de los resultados del modelo del acufero. Considerando escenarios de cambio climtico IPCC, se ha aplicado el enfoque integrado a la evaluacin del impacto de dicho cambio climtico en el ciclo hidrolgico de la cuenca del Geer. Se describe los detalles y resultados del modelo de las aguas subterrneas en trminos del impacto del cambio climtico en la evolucin de las reservas de los acuferos. Los resultados preliminares indican que es posible esperar dficits de aguas subterrneas en un futuro en Blgica.

We carried out a pilot study with four couples to evaluate the feasibility of the intervention and the aspects of content and format that needed to be modified. Findings reflect that participants were very satisfied with the intervention and they found it entertaining and innovative. They were very comfortable with its format, as well as with the activities. The findings confirm the feasibility of this intervention and the need to direct preventive efforts to this population. PMID:23847716

Reconnaissance evaluation of Honduran geothermal sites. Una evaluacion por medio de reconocimiento de seis areas geotermicas en Honduras  

SciTech Connect

Six geothermal spring sites were selected on the basis of preliminary investigations conducted in Honduras over the last decade and were evaluated in terms of their development potential. Of the six, the Platanares and San Ignacio sites have high base temperatures and high surface fluid discharge rates and appear to have the best potential for further development as sources of electrical power. A third site, Azacualpa, has a high enough base temperature and discharge rate to be considered as a back-up, but the logistical problems involved in geophysical surveys make it less attractive than the two primary sites. Of the remaining three sites, Pavana may be a source of direct-use heat for local agricultural processing. Sambo Creek and El Olivar have either severe logistical problems that would impede further investigation and development or base temperatures and flow rates that are too low to warrant detailed investigation at this time.

Hydrochemical tracers in the middle Rio Grande Basin, USA: 1. Conceptualization of groundwater flow  

NASA Astrophysics Data System (ADS)

Chemical and isotopic data for groundwater from throughout the Middle Rio Grande Basin, central New Mexico, USA, were used to identify and map groundwater flow from 12 sources of water to the basin, evaluate radiocarbon ages, and refine the conceptual model of the Santa Fe Group aquifer system. Hydrochemical zones, representing groundwater flow over thousands to tens of thousands of years, can be traced over large distances through the primarily siliciclastic aquifer system. The locations of the hydrochemical zones mostly reflect the ``modern'' predevelopment hydraulic-head distribution, but are inconsistent with a trough in predevelopment water levels in the west-central part of the basin, indicating that this trough is a transient rather than a long-term feature of the aquifer system. Radiocarbon ages adjusted for geochemical reactions, mixing, and evapotranspiration/dilution processes in the aquifer system were nearly identical to the unadjusted radiocarbon ages, and ranged from modern to more than 30 ka. Age gradients from piezometer nests ranged from 0.1 to 2 year cm-1 and indicate a recharge rate of about 3 cm year-1 for recharge along the eastern mountain front and infiltration from the Rio Grande near Albuquerque. There has been appreciably less recharge along the eastern mountain front north and south of Albuquerque. Des donnes sur les lments chimiques et les isotopes prsents dans l'eau souterraine prleve divers endroits dans le bassin moyen du Rio Grande, au centre du Nouveau-Mexique (-U), ont permis de dterminer l'existence et l'tendue de douze sources d'eau rgionales dans le bassin, d'valuer les ges radiocarbones et de raffiner le modle conceptuel du systme aquifre du groupe de Santa Fe. Des zones hydro-chimiques qui reprsentent l'coulement de l'eau souterraine depuis des dizaines de milliers d'annes peuvent tre suivies sur de longues distances travers l'aquifre principalement siliclastique. La position des zones hydro-chimiques reflte principalement la distribution moderne des charges hydrauliques mais est incohrente avec une dpression dans le niveau d'eau dans la partie centre-ouest du bassin, ce qui indique que cette dpression est un lment transitoire du systme aquifre plutt qu'un lment long terme. Les ges radiocarbones ajusts aux ractions gochimiques et aux processus de mlange et d'vapotranspiration/dilution qui ont lieu dans l'aquifre sont presque identiques aux ges non ajusts et varient de la priode moderne jusqu' 30 ka. Les gradients d'ge tablis partir des nids de pizomtres s'tendent de 0.1 2 a cm-1 et suggrent un taux de recharge d'environ 3 cm a-1 le long du front des montagnes l'est et pour l'infiltration provenant du Rio Grande prs d'Albuquerque. Il y a eu substantiellement moins de recharge le long du front des montagnes l'est, au nord et au sud d'Albuquerque. Se utilizaron datos qumicos e isotpicos de agua subterrnea a lo largo de la cuenca central del ro Grande, Nuevo Mxico, EEUU, para identificar y mapear el flujo de agua subterrnea de 12 fuentes de agua a la cuenca para evaluar edades por medio de radio carbon y para refinar el modelo conceptual del sistema acufero del Grupo Santa F. Se puede establecer zonas hidrotrmicas que representan el flujo de agua subterrnea a lo largo de miles a miles de decenas de aos en grandes distancias a travs del sistema acufero principalmente siliclstico. Las ubicaciones de las zonas hidroqumicas mayormente reflejan la distribucion de la cabeza hidrulica pre-desarollo moderna pero son inconsistentes con una depresin en los niveles de agua pre-desarollo en la zona central oeste de la cuenca. Esto indica que esta depresin es un rasgo transitorio y no un rasgo de largo plazo del sistema acufero. Las edades de radio carbon ajustadas para los procesos de reaciones geoqumicas, de mezclado y de evapotranspiracin-dilucin son casi idnticas a los edades de radio carbon no ajustadas oscilan en un rango desde la

The influence of faults in basin-fill deposits on land subsidence, Las Vegas Valley, Nevada, USA  

NASA Astrophysics Data System (ADS)

The role of horizontal deformation caused by pumping of confined-aquifer systems is recognized as contributing to the development of earth fissures in semiarid regions, including Las Vegas Valley, Nevada. In spite of stabilizing water levels, new earth fissures continue to develop while existing ones continue to lengthen and widen near basin-fill faults. A three-dimensional granular displacement model based on Biot's consolidation theory (Biot, MA, 1941, General theory of three-dimensional consolidation. Jour. Applied Physics 12:155-164) has been used to evaluate the nature of displacement in the vicinity of two vertical faults. The fault was simulated as (1) a low-permeability barrier to horizontal flow, (2) a gap or structural break in the medium, but where groundwater flow is not obstructed, and (3) a combination of conditions (1) and (2). Results indicate that the low-permeability barrier greatly enhances horizontal displacement. The fault plane also represents a location of significant differential vertical subsidence. Large computed strains in the vicinity of the fault may suggest high potential for failure and the development of earth fissures when the fault is assumed to have low permeability. Results using a combination of the two boundaries suggest that potential fissure development may be great at or near the fault plane and that horizontal deformation is likely to play a key role in this development. Rsum. On considre que la dformation horizontale provoque par un pompage dans un aquifre captif joue un rle dans le dveloppement des fissures du sol en rgions semi-arides, comme la valle de Las Vegas (Nevada). Malgr des niveaux d'eau stabiliss, de nouvelles fissures du sol continuent de se dvelopper en longueur et en largeur au voisinage de failles dans les bassins sdimentaires. Un modle de dplacement granulaire tri-dimensionnel, bas sur la thorie de la consolidation de Biot (Biot, M A, 1941, General theory of three-dimensional consolidation. Jour. Applied Physics 12:155-164), a t utilis pour valuer la nature du dplacement au voisinage de deux failles verticales. La faille a t simule comme 1) une barrire de faible permabilit pour l'coulement horizontal, 2) une rupture structurale dans le milieu, mais sans obstruction de l'coulement, et 3) une combinaison des deux prcdentes conditions. Les rsultats indiquent que la barrire de faible permabilit favorise fortement le dplacement horizontal. Le plan de faille constitue aussi un lieu de subsidence diffrentielle verticale significative. Les fortes contraintes calcules au voisinage de la faille laissent penser qu'il existe un fort potentiel de rupture et le dveloppement de fissures du sol quand on suppose que la faille possde une faible permabilit. Les rsultats utilisant une combinaison des deux conditions suggrent que le dveloppement potentiel de fissures peut tre grand sur ou proximit du plan de faille et que la dformation horizontale joue vraisemblablement un rle cl dans ce dveloppement. Resumen. Se conoce la contribucin que la deformacin horizontal causada por el bombeo de sistemas acuferos confinados tienen en el desarrollo de fisuras en regiones semiridas, como es el caso del Valle de Las Vegas (Nevada, Estados Unidos de Amrica). A pesar de la estabilizacin de los niveles, se contina desarrollando nuevas fisuras, mientras las ya existentes se alargan y ensanchan cerca de las fallas de relleno de cuenca. Se ha utilizado un modelo tridimensional de desplazamiento granular basado en la teora de consolidacin de Biot (Biot, M.A., 1941. General theory of three-dimensional consolidation. J. Applied Physics, 12: 155-164) para evaluar la naturaleza del desplazamiento junto a dos fallas verticales. Se ha simulado cada falla como (1) una barrera de baja permeabilidad al flujo horizontal, (2) un hueco o ruptura estructural en el medio pero sin obstruccin al flujo de aguas subterrneas, y (3) una combinacin de las dos condiciones anteriores.

Distribution of stable isotopes in arid storms . I. Relation between the distribution of isotopic composition in rainfall and in the consequent runoff  

NASA Astrophysics Data System (ADS)

Temporal distributions of the isotopic composition in arid rain storms and in the associated runoff were investigated in a small arid rocky basin in Israel. Customized rain and runoff samplers provided sequential water samples hermetically sealed in high-density PVC bags. In several storms where the runoff was isotopically depleted, compared with the rainfall, the difference could not be explained by fractionation effects occurring during overland flow. A water-balance study relating the runoff discharge to rainfall over a rocky watershed showed that the entire discharge is produced by a very small segment (1-2mm) of the rain storm. The major objective, therefore, was to provide quantitative relations between segments of rainfall (rain showers and rain spells) and runoff. The time distribution of the composition of stable isotopes (oxygen and hydrogen) was used to quantify the correlation between the rain spell's amount and the consequent runoff. The aim of this work was to (a) utilize the dynamic variations in the isotopic composition in rainfall and runoff and model the magnitude of surface-storage capacity associated with runoff processes of overland flow, and (b) characterize the isotopic composition of the percolating water with respect to the isotopic distribution in rainfall and runoff events. The conceptual model postulates an isotopic mixing of overland flow with water within the depression storage. A transport model was then formulated in order to estimate the physical watershed parameters that control the development of overland flow from a certain rainfall period. Part I (this paper) presents the results and the assessment of the relative depression storage obtained from oxygen-18 and deuterium analyses that lead to the physical and mathematical formulation of a double-component model of kinematic-wave flow and transport, which is presented in Part II (accompanying paper). Rsum Les variations temporelles, en zone aride, de la composition isotopique des prcipitations et du ruissellement associ ont ttudies dans un petit bassin rocheux aride en Isral. Des prleveurs spcialement adapts pour la pluie et le ruissellement ont fourni des chantillons squentiels dans des sacs en PVC haute densit hermtiquement ferms. Au cours de plusieurs pisodes pluvieux o le ruissellement tait isotopiquement appauvri par rapport la pluie, la diffrence ne pouvait pas tre explique par des effets de fractionnement intervenant au cours de l'coulement en surface. Un bilan hydrologique rapportant l'coulement de surface la pluie sur un bassin versant rocheux montre que l'coulement dans sa totalit est aliment par une trs petite partie (1-2mm) de l'averse. C'est pourquoi l'objectif essentiel a t de rechercher des relations quantitatives entre des parties de la pluie (averses et pisodes pluvieux) et le ruissellement. La rpartition temporelle de la composition en isotopes stables (oxygne et hydrogne) a t utilise pour quantifier la corrlation entre la hauteur tombe pendant l'pisode pluvieux et le ruissellement produit. Le but de ce travail tait (a) d'utiliser les variations dynamiques de la composition isotopique dans la pluie et dans le ruissellement pour modliser l'ordre de grandeur de la capacit de stockage de surface associe aux processus de ruissellement de l'coulement de surface, et (a) de caractriser la composition isotopique de l'eau d'infiltration par rapport la variation isotopique observe dans les pluies et dans les coulements correspondants. Resumen La distribucin temporal de la composicin isotpica de las tormentas en zonas ridas y la correspondiente escorrenta se analiz en una pequea cuenca rocosa en Israel. Los medidores de lluvia y escorrenta proporcionaron muestras de agua secuenciales, selladas hermticamente en bolsas de PVC de alta densidad.

Factores predictores de inicio y cesaci?n de tabaquismo en una cohorte de mujeres chilenas con 5,5 a?os de seguimiento  

PubMed Central

Background Chilean women have one of the highest smoking prevalence in the world. Aim To estimate the main factors associated with smoking initiation and quitting among a cohort of adult women living in a low socioeconomic status area of Santiago, Chile. Material and methods A random population-based sample of 1,100 women, 18 years and older, were selected from a community located in the South East area of Santiago. Sociodemographic, as well as smoking, beliefs, behaviors, stages of change and nicotine addiction level were recorded during a personal interview. After an average follow-up period of 5.5 years, women were re-evaluated. Results Seventy-three percent of women completed the study. At baseline, 39% of women were smokers. At the end of the study, there was an absolute smoking rate reduction of 7.1% (p<0.001). The main variables associated with smoking initiation were younger age (Odds ratio (OR): 1.08, 95% confidence intervals (CI): 1.051.12), higher education level (OR: 1.2, 95% CI: 1.071.35), and having fewer children (OR: 1.3 95% CI: 1.011.66). Factors related with quitting were younger age of onset (OR: 1.06 95% CI: 1.021.1), higher level of nicotine dependence (OR: 4.22, 95% CI: 1.7410.27), and higher perception of smoking addiction (OR: 4.34, 95% CI: 29.09). Stage of change was associated with smoking cessation but its effect was diluted after adjusting for the level of nicotine addiction. Conclusions Sociodemographic and family factors were the main variables related with initiation, whereas age of onset, belief of addiction, and nicotine dependence were the main factors related with cessation. Women with a high motivation for quitting should be evaluated for nicotine addiction level to define the best strategy for intervention (Rev Md Chile 2009; 137: 10019). PMID:19915762

Is Spanish time schedule really weird? // De verdad son tan an\\'omalos los horarios espa\\~noles? Una comparaci\\'on con Italia y Reino Unido  

E-print Network

There are currently a vivid debate in Spain on the time zone which should follow the country. In this context this paper analyses Time Use surveys in Spain, Italy and United Kingdom and compares data extracted from them. The paper focus on universal activities like: sleeping, eating, working and the location "at home". Data are analysed on the regional basis provided by the surveys. Regional distributions of first and last occurrences of the activities are described by median values. Median values are then compared to each other by considering longitude and latitude. Within the interval of half a time zone, data show a good agreement. Which is to say, Spanish time schedules are not really weird if geographical position is taken into account. That includes also latitude. It is shown that midlatitude regions may undergo earlier time tables in the morning. ---- En el contexto de la discusi\\'on actual que se vive en Espa\\~na sobre la pertinencia de sus horarios y sobre el huso horario que ha de regir en el pa\\'is...

In this chapter, the theory of Lifshitz, Slesov and Wagner and the technique of Emulsion Stability Simulations (ESS) are reviewed. Complementary algorithms required to incorporate the phenomenon of Ostwald ripening in ESS are presented. The simulations are used to study the behavior of dodecane-in-water nanoemulsions as a function of time. The influence of electrostatic interactions, hydration forces, the initial drop size distributions, and the deformability of the drops, are studied. In particular, the behavior of the cube average radius of the dispersion and the variation of the drop size distribution a few minutes after the preparation of the emulsion are described.

Groundwater targeting in a hard-rock terrain using fracture-pattern modeling, Niva River basin, Andhra Pradesh, India  

NASA Astrophysics Data System (ADS)

In hard-rock terrain, due to the lack of primary porosity in the bedrock, joints, fault zones, and weathered zones are the sources for groundwater occurrence and movement. To study the groundwater potential in the hard-rock terrain and drought-prone area in the Niva River basin, southern Andhra Pradesh state, India, Landsat 5 photographic data were used to prepare an integrated hydrogeomorphology map. Larsson's integrated deformation model was applied to identify the various fracture systems, to pinpoint those younger tensile fracture sets that are the main groundwater reservoirs, and to understand the importance of fracture density in groundwater prospecting. N35-55E fractures were identified as tensile and N35-55W fractures as both tensile and shear in the study area. Apparently, these fractures are the youngest open fractures. Wherever N35-55E and N35-55W fracture densities are high, weathered-zone thickness is greater, water-table fluctuations are small, and well yields are high. Groundwater-potential zones were delineated and classified as very good, good to very good, moderate to good, and poor. Rsum. Dans les roches de socle, l'absence de porosit primaire dans la roche fait que les fractures, les zones de faille et les zones d'altration sont les sites o l'eau souterraine est prsente et s'coule. Pour tudier le potentiel en eau souterraine dans la rgion de socle sujette la scheresse du bassin de la rivire Niva (sud de l'tat d'Andhra Pradesh, Inde), des donnes photographiques de Landsat 5 ont t utilises pour prparer une carte hydro-gomorphologique. Le modle intgr de dformation de Larssons a t mis en uvre pour identifier les diffrents systmes de fractures, pour mettre l'accent sur les ensembles de fractures en extension les plus jeunes qui constituent les principaux rservoirs d'eau souterraine, et pour comprendre l'importance de la densit de fractures pour la prospection de l'eau souterraine. Dans la rgion tudie, les fractures N35-55E ont t identifies comme tant en extension, et les fractures N35-55W comme tant la fois en extension et en cisaillement. Ces fractures sont apparemment les fractures ouvertes les plus jeunes. Partout o la densit des fractures N35-55E et N35-55W est leve, la zone altre est plus paisse, les fluctuations de la nappe sont faibles et les rendements des puits sont forts. Des zones potentiel en eau souterraine ont ainsi t dlimites et classes en excellent, bon trs bon, assez bon et mdiocre. Resumen. Las zonas de fracturacin y de meteorizacin son las que condicionan el flujo de agua subterrnea en rocas duras, debido a la falta de porosidad primaria en la matriz rocosa. Se utilizaron cinco conjuntos de datos fotogrficos del satlite Landsat con el fin de preparar un mapa integrado hidrogeomorfolgico de la cuenca del ro Niva, al sur del estado Andhra Pradesh (India). El objetivo era estudiar el potencial de aguas subterrneas en esta regin, que es propensa a perodos de sequa, en la que predominan las rocas duras. Se aplic el modelo de deformacin integrado de Larsson a la identificacin de los sistemas de fracturacin. El propsito era, por un lado, identificar los conjuntos de fracturas de traccin ms jvenes, que desempean un papel principal como reservorios de aguas subterrneas. Por otro lado, se quera comprender la importancia de la densidad de fracturacin en el desarrollo de las aguas subterrneas. Se identific una familia de fracturas de traccin con orientacin N35-55E y otra familia N35-55W que contena tanto bandas de cizalla como fracturas de traccin. Aparentemente, se trataba de las fracturas abiertas ms recientes. El espesor de la zona de meteorizacin es grande cuando la densidad de fracturas de estas dos familias es elevada, hecho que est asociado a fluctuaciones pequeas del nivel fretico y a caudales elevados. Se estableci una clasificacin de las aguas subterrneas como zona

Groundwater flow and solute transport at the Mourquong saline-water disposal basin, Murray Basin, southeastern Australia  

NASA Astrophysics Data System (ADS)

Saline groundwater and drainage effluent from irrigation are commonly stored in some 200 natural and artificial saline-water disposal basins throughout the Murray-Darling Basin of Australia. Their impact on underlying aquifers and the River Murray, one of Australia's major water supplies, is of serious concern. In one such scheme, saline groundwater is pumped into Lake Mourquong, a natural groundwater discharge complex. The disposal basin is hydrodynamically restricted by low-permeability lacustrine clays, but there are vulnerable areas in the southeast where the clay is apparently missing. The extent of vertical and lateral leakage of basin brines and the processes controlling their migration are examined using (1) analyses of chloride and stable isotopes of water (2H/1H and 18O/16O) to infer mixing between regional groundwater and lake water, and (2) the variable-density groundwater flow and solute-transport code SUTRA. Hydrochemical results indicate that evaporated disposal water has moved at least 100 m in an easterly direction and that there is negligible movement of brines in a southerly direction towards the River Murray. The model is used to consider various management scenarios. Salt-load movement to the River Murray was highest in a "worst-case" scenario with irrigation employed between the basin and the River Murray. Present-day operating conditions lead to little, if any, direct movement of brine from the basin into the river. Rsum. Les eaux souterraines sales et les effluents de drainage de l'irrigation sont stocks dans environ 200 bassins naturels ou artificiels destins retenir les eaux salines dans tout le bassin de Murray-Darling, en Australie. Leur impact sur les aquifres sous-jacents et sur la rivire Murray, l'une des principales ressources en eau d'Australie, constitue un problme grave. Dans une telle situation, les eaux souterraines salines sont pompes dans le lac Mourquong, complexe dans lequel les nappes se dchargent naturellement. Le bassin de stockage est isol hydrodynamiquement par des argiles lacustres de faible permabilit, mais il existe des zones vulnrables au sud-est, l o les argiles sont apparemment absentes. L'importance des fuites verticales et latrales des saumures du bassin et les processus contrlant leur migration ont t tudis au moyen (1) d'analyses de chlorures et des isotopes stables de l'eau (2H/1H et 18O/16O) pour dfinir le mlange entre les eaux souterraines rgionales et l'eau du lac, et (2) du code SUTRA d'coulement souterrain et de transport de solut d'eaux de densits variables. Les rsultats hydrochimiques indiquent que l'eau de stockage vapore s'est introduite d'au moins 100 m vers l'est et qu'il existe un coulement ngligeable de saumures vers le sud, en direction de la rivire Murray. Le modle permet de considrer diffrents scnarios de gestion. L'coulement des eaux sales vers la rivire Murray tait le scnario le pire du fait de l'irrigation qui est applique entre le bassin de stockage et la rivire Murray. Les conditions actuelles de fonctionnement produisent un coulement direct faible, sinon nul, des saumures du bassin vers la rivire. Resumen. Las aguas subterrneas salinas y los retornos de riego se almacenan habitualmente en unas 200 balsas naturales y artificiales de deshechos, situadas a lo largo de la Cuenca de los ros Murray-Darling (Australia). Su impacto en los acuferos y en el propio ro Murray, que acta como una de las fuentes principales de abastecimiento de agua en Australia, es un asunto preocupante. En uno de estos lugares, las aguas subterrneas salinizadas son bombeadas al lago Mourquong, que es un complejo natural de descarga del acufero. La balsa de eliminacin est revestida con arcillas lacustres de baja permeabilidad, pero hay reas vulnerables hacia el sudeste, donde parece no haber arcilla. Se examina el alcance de la precolacin vertical y lateral de las salmueras contenidas en la balsa y de los procesos que controlan su migracin por me

Interpretation of tracer tests performed in fractured rock of the Lange Bramke basin, Germany  

NASA Astrophysics Data System (ADS)

Two multitracer tests performed in one of the major cross-fault zones of the Lange Bramke basin (Harz Mountains, Germany) confirm the dominant role of the fault zone in groundwater flow and solute transport. Tracers having different coefficients of molecular diffusion (deuterium, bromide, uranine, and eosine) yielded breakthrough curves that can only be explained by a model that couples the advective-dispersive transport in the fractures with the molecular diffusion exchange in the matrix. For the scale of the tests (maximum distance of 225m), an approximation was used in which the influence of adjacent fractures is neglected. That model yielded nearly the same rock and transport parameters for each tracer, which means that the single-fracture approximation is acceptable and that matrix diffusion plays an important role. The hydraulic conductivity of the fault zone obtained from the tracer tests is about 1.510-2m/s, whereas the regional hydraulic conductivity of the fractured rock mass is about 310-7m/s, as estimated from the tritium age and the matrix porosity of about 2%. These values show that the hydraulic conductivity along the fault is several orders of magnitude larger than that of the remaining fractured part of the aquifer, which confirms the dominant role of the fault zones as collectors of water and conductors of fast flow. Rsum Deux multitraages ont t raliss dans l'une des zones principales de failles du bassin de Lange Bramke (massif du Harz, Allemagne); les rsultats confirment le rle prdominant de la zone de failles pour l'coulement souterrain et le transport de solut. Les traceurs, possdant des coefficients de diffusion diffrents (deutrium, bromure, uranine et osine), ont fourni des courbes de restitution qui ne peuvent tre expliques que par un modle qui associe un transport advectif-dispersif dans les fractures un change par diffusion molculaire dans la matrice. A l'chelle des expriences (distance maximale de 225m), l'influence des fractures adjacentes a t nglige. Ce modle a fourni pour chaque traceur pratiquement les mmes paramtres pour la roche et le transport, ce qui signifie que l'approximation de la fracture unique est acceptable et que la diffusion dans la matrice joue un rle important. La conductivit hydraulique de la zone de faille fournie par les traages est d'environ 1,510-2m/s, alors que la conductivit hydraulique rgionale de la roche fracture dans son ensemble est de l'ordre de 310-7m/s, selon l'estimation tire des ges tritium et de la porosit de la matrice d'environ 2%. Ces valeurs montrent que la conductivit hydraulique le long de la faille est suprieure de plusieurs ordres de grandeur celle de la partie fracture restante de l'aquifre, ce qui confirme le rle prdominant jou par les zones de failles comme drains de l'eau et comme axes d'coulement rapide. Resumen Dos ensayos con mltiples trazadores realizados en una de las zonas ms fracturadas de la cuenca de Lange Bramke (Montes Harz, Alemania) confirman el papel dominante de la zona de fractura en el flujo de agua subterrnea y el transporte de solutos. Trazadores con distintos coeficientes de difusin molecular (deuterio, bromuro, uranina y eosina) dieron curvas de llegada que slo pueden ser explicadas mediante un modelo que acople el transporte advectivo-dispersivo en las fracturas con la difusin en la matriz. Para la escala de los ensayos (distancia mxima de 225m), se us como aproximacin que la influencia de las fracturas adyacentes poda despreciarse. Este modelo dio lugar para cada trazador a valores muy similares de los parmetros de transporte, lo que supone que la aproximacin de fractura nica es aceptable y que la difusin en la matriz es un mecanismo importante. La conductividad hidrulica de la zona fracturada obtenida de los ensayos es de unos 1.510-2m/s, mientras que la conductividad hidrulica regional para la matriz rocosa es de unos 310-7m/s, valor estimado de la edad del tritio y la porosidad

Science, nature, and tradition: the mass-marketing of natural medicine in urban Ecuador.  

PubMed

In the past 15 years, "natural" medicine has become increasingly popular in the southern Ecuadoran city of Cuenca. Natural medicine products, which are distinct from traditional herbal remedies, are commercially packaged and processed and sold in a number of retail outlets in the central shopping district. This article discusses the results of field research to determine the client base of natural medicine and the reasons for its growing popularity among the poorer classes in Ecuador. Using an interpretative framework that posits that medical products carry symbolic messages, I discuss the ways in which important themes of modern life in Ecuador are played out in the packaging and marketing of these products. This research supports the growing body of literature that argues against a medical-systems approach to analyzing medical plurality by highlighting the multiple ideologies found in Ecuadoran beliefs about commercial natural medicine.

Community embedded reproductive health interventions for adolescents in Latin America: development and evaluation of a complex multi-centre intervention  

PubMed Central

Background Adolescents in Latin America are at high risk for unwanted and unplanned pregnancies, which often result in unsafe abortions or poor maternal health outcomes. Both young men and women in the region face an increased risk of sexually transmitted infections due to inadequate sexual and reproductive health information, services and counselling. To date, many adolescent health programmes have targeted a single determinant of sexual and reproductive health. However, recent evidence suggests that the complexity of sexual and reproductive health issues demands an equally multi-layered and comprehensive approach. Methods This article describes the development, implementation and evaluation design of the community-embedded reproductive health care for adolescents (CERCA) study in three Latin American cities: Cochabamba (Bolivia), Cuenca (Ecuador) and Managua (Nicaragua). Project CERCAs research methodology builds on existing methodological frameworks, namely: action research, community based participatory research and intervention-mapping. The interventions in each country address distinct target groups (adolescents, parents, local authorities and health providers) and seek improvement of the following sexual health behaviours: communication about sexuality, sexual and reproductive health information-seeking, access to sexual and reproductive health care and safe sexual relationships. In Managua, we implemented a randomised controlled study, and in Cochabamba and Cuenca we adopted a non-randomised controlled study to evaluate the effectiveness of Project CERCA interventions, in addition to a process evaluation. Discussion This research will result in a methodological framework that will contribute to the improved design and implementation of future adolescent sexual and reproductive health interventions.
