Quantifying Mechanisms of Aquifer Salinization at the Alto Piura Valley, Northern Part of Peru  

NASA Astrophysics Data System (ADS)

The Alto Piura aquifer (Peruvian northern coastal area) supports the important agricultural activity in the region and provides water supply for 150,000 residents. Recent studies show a salinization process in the northwest area of the aquifer. Further groundwater degradation could create economic and social problems for the region. An infiltration-tracer test in a typical agricultural field of the Alto Piura region was carried out to explore water and solute transport mechanisms. The main objective was to mimic the mechanism of flood irrigation (25 cm head once a month) typically used by Peruvian farmers in banana plots. Soil and groundwater contaminations were monitored in a 3x3 m area and a calcium chloride solution (3.07 m3) was injected as a tracer during the irrigation event. The initial and final conditions of the soil profile were studied by drilling three boreholes inside and one outside the plot prior to, and 2, 4, 7 and 10 days following the irrigation event. In total, 289 soil samples were collected to follow the gravimetric water content (GWC) and electrical conductivity (EC) profiles during the experiment. Soil samples were extracted in 20 cm resolution from the upper 2 m and 50 cm resolution for the rest of soil profile to 4.5 m, the initial watertable depth. Likewise, thirty groundwater samples were taken and analyzed for major ions, EC, and total dissolved solids (TDS). Bulk density and soil texture were also measured along the soil profiles. The GWC profiles indicated faster water movement through the unsaturated zone with respect to the salt movement. An infiltration test using double ring infiltrometer estimated Ks value of 0.24 m day-1.The EC soil profiles indicated a clear salt accumulation in the first 1 m layer that did not manifest changes until the end of the 10 day measurement period. Groundwater salinity varied within the 3x3 m zone. It increased, decreased or changed with time in respect to the initial salinity. This variability within the limited 3x3 m zone, suggests that preferential flow played a major role in the salt transport. The preferential transport of salts in some areas suggests that fertilization and flood irrigation events will produce both soil and groundwater salinization. Hydrus 2D/3D model was used to simulate water flow and solute transport of the infiltration test. GWC data, TDS values and watertable readings were used to calibrate soil hydraulic properties and dispersivity values. The simulation suggest a combined mechanism of salinization: the flood irrigation flushes down to the aquifer the accumulated solute from the first 1 m layer, producing new salt accumulation in the soil profile originating from external sources such as fertilizers. Simulations based on conventional Richards’ equation showed the necessity to incorporate preferential flow processes on a field-scale. Modeling of flow and transport in the aquifer, considering the irrigation return flow effect, presents the challenging avenue of the ongoing research.

Modeling the impact of solute recycling on groundwater salinization under irrigated lands: A study of the Alto Piura aquifer, Peru  

NASA Astrophysics Data System (ADS)

SummaryStudies of groundwater quality in arid and semi-arid lands show that irrigation return flow is one of major factors contributing to aquifer salinization. Existing mathematical models do not account explicitly for solute recycling during irrigation on a daily scale, which is considered as an important salinization input. The main objective of this research was to develop a mathematical numerical model that can simulate impact of irrigation return flow by coupling water and solute fluxes at the soil surface with quality of water pumped from the aquifer. This was obtained with a Quasi-3D model representing flow in the vadose zone - aquifer system by series of 1D Richards' equations in a variably-saturated zone and by a 3D flow equation in groundwater. The 3D advection-dispersion equation is solved in the entire domain. Concentration of irrigation water is calculated at each time step as a function of concentration of both surface water and groundwater extracted at specific locations. The model was applied to simulate the impact of irrigation on groundwater salinization of Alto Piura aquifer (Northern Peru) over thirty years. Three scenarios were considered: (i) use of flood irrigation and groundwater extraction (the present situation); (ii) increase of groundwater pumping by 50% compared to the first scenario; and (iii) transition from flood irrigation to drip irrigation, thus decreasing irrigation volume by around 60% compared to the first scenario. Results indicate that in different irrigation areas, the simulated increase rates of total dissolved solids in groundwater vary from 3-5 to 15-17 mg/L/year, depending on hydrogeological and hydrochemical conditions, volumes of water extracted, and proportion between surface water and groundwater applied. The transition from flood irrigation to drip irrigation decreases the negative impact of return flow on groundwater quality; however drip irrigation causes faster soil salinization compared to flood irrigation. Irrigation return coefficients were calculated in the order of 21-23% and 22-24% for the first and second scenarios, respectively.

Impedance comparison of high-quality alto and soprano saxophones  

NASA Astrophysics Data System (ADS)

Measuring the input impedance of high-quality wind instruments requires both a system able to provide the physical quantity in less than a few seconds and the possibility to do the measurement on a wide number of instruments. If we have such a system measuring system giving us the possibility to obtain impedance curves for the whole musical range of the instrument the second condition cannot be achieved without the strong collaboration of an instrument maker. The present study has been realized on Selmer saxophones and on instrmuents from two other factories. They include vintage instruments (as Mark VI) and the most recent commercialized ones. It allows one to study the evolution of the instruments. We will show that some alto saxophone models have reached an incredible harmonicity of their resonances while less common models present other characteristics. We will discuss these results and their relations with the audible quality of the instruments.

It uses a mosaic of four Hawaii-2RG detectors and covers the spectral range from 0.8-2.5 ?m (z to K-band). The field-of-view is 30×30 arcmin. This instrument can be used at the 2.2m telescope (0.45arcsec/pixel, 0.5×0.5 degree FOV) and at the 3.5m telescope (0.23arcsec/pixel, 0.25×0.25 degree FOV). The operating temperature is about 77K, achieved by liquid Nitrogen cooling. The cryogenic optics has three flat folding mirrors with diameters up to 282 mm and nine lenses with diameters between 130 mm and 255 mm. A compact filter unit can carry up to 19 filters distributed over four filter wheels. Narrow band (1%) filters can be used. The instrument has a diameter of 1.1 m and it is about 1 m long. The weight limit of 400 kg at the 2.2m telescope requires a light-weight cryostat design. The aluminium vacuum vessel and radiation shield have wall thicknesses of only 6 mm and 3 mm respectively.

The model of brief therapy developed by Fisch, Weakland, Watzlawick, and colleagues in Palo Alto is based on identifying and interrupting ironic processes that occur when repeated attempts to solve a problem keep the problem going or make it worse. Formulations of ironic problem-solution loops provide a template for assessment and strategic intervention, indicating where to look to understand what keeps a problem going (look for “more of the same” solution) and what needs to happen for the complaint to be resolved (someone must apply “less of the same” solution). Supporting research is preliminary but suggests this approach may be well suited for change-resistant clients. PMID:19997533

Petrology and geochemistry of Alto Peak, a vapor-cored hydrothermal system, Leyte Province, Philippines  

SciTech Connect

Based on detailed petrological information on secondary mineral assemblages and the composition of fluids trapped in inclusions and discharged from five wells, the Alto Peak geothermal field was found to represent a combined vapor and liquid-dominated system. A central core or chimney, with a diameter of about 1 km, a height of some 3 km and occupied by a high gas vapor (1.1 to 5.6 molal CO{sub 2}), is surrounded by an envelope of intermediate salinity water (7,000 mg/kg Cl) with temperatures between 250 and 350 C. The transition from purely vapor-dominated to liquid-dominated zones takes place via two-phase zones occupied by fluid mixtures of highly variable compositions. Much of the lower temperature, mature neutral pH Cl water is likely to have formed during an earlier stage in the evolution of the system. High temperatures of > 300 C, and associated alteration, are limited to wells AP-1D and the lower parts of AP-2D and are ascribed to re-heating by recent magmatic intrusions. The isotopic composition of the well discharges suggests that they contain some 40 to 50% of magmatic water. Alto Peak is considered a typical example of hydrothermal systems associated with many dormant volcanoes.

Fuel dynamics by using Landscape Ecology Indices in the Alto Mijares, Spain  

NASA Astrophysics Data System (ADS)

Land abandonment in Mediterranean regions has brought about a number of management problems, being an increased wildfire activity prevalent among them. Agricultural neglect in highlands resulted in reduced anthropogenic disturbances and greater landscape homogeneity in areas such as the Alto Mijares in Spain. It is widely accepted that processes like forest fires, influence structure of the landscape and vice versa. Fire-prone Mediterranean flora is well adapted to this disturbance, exhibiting excellent succession capabilities; but higher fuel loads and homogeneous conditions may ally to promote vegetation recession when the fire regime is altered by land abandonment. Both succession and recession make changes to the landscape structure and configuration. However, these changes are difficult to quantify and characterize. If landscape restoration of these forests is a management objective, then developing a quantitative knowledge base for landscape fuel dynamics is a prerequisite. Four classified LandsatTM satellite images were compared to quantify changes in landscape structure between 1984 and 1998. An attempt is made to define landscape level dynamics for fuel development after reduced disturbance and fuel accumulation that leads to catastrophic fires by using landscape ecology indices. By doing so, indices that best describe the fuel dynamics are pointed. The results indicate that low-level disturbance increases heterogeneity, thus lowers fire hazard. No disturbance or severe disturbance increases homogeneity because of vegetation succession and may lead to devastating fires. These fires could be avoided by human induced disturbance like controlled burning, harvesting, mechanical works for fuel reduction and other silviculture measures; thus bringing in more heterogeneity in the region. The Alto Mijares landscape appears to be in an unstable equilibrium where succession and recession are at tug of war. The effects are evident in the general absence of the climax species of Quercus ilex. It have also been recognised that just one index is rarely sufficient to describe the complex dynamics in any landscape; it is usually a group of indices that needs to be consulted in order to perceive the wider picture. The study indicates that there is a need for landscape and social restoration in areas like Alto Mijares to make best use of available resources and avoid catastrophic fires.

Sedimentation survey of Lago Loíza, Trujillo Alto, Puerto Rico, July 2009  

USGS Publications Warehouse

Lago Loíza is a reservoir formed at the confluence of Río Gurabo and Río Grande de Loíza in the municipality of Trujillo Alto in central Puerto Rico, about 10 kilometers (km) north of the town of Caguas, about 9 km northwest of Gurabo, and about 3 km south of Trujillo Alto (fig. 1). The Carraizo Dam is owned and operated by the Puerto Rico Aqueduct and Sewer Authority (PRASA), and was constructed in 1953 as a water-supply reservoir for the San Juan Metropolitan area. The dam is a concrete gravity structure that is located in a shallow valley and has a gently sloping left abutment and steep right abutment. Non-overflow sections flank the spillway section. Waterways include an intake structure for the pumping station and power plant, sluiceways, a trash sluice, and a spillway. The reservoir was built to provide a storage capacity of 26.8 million cubic meters (Mm3) of water at the maximum pool elevation of 41.14 meters (m) above mean sea level (msl) for the Sergio Cuevas Filtration Plant that serves the San Juan metropolitan area. The reservoir has a drainage area of 538 square kilometers (km2) and receives an annual mean rainfall that ranges from 1,600 to 5,000 millimeters per year (mm/yr). The principal streams that drain into Lago Loíza are the Río Grande de Loíza, Río Gurabo, and Río Cañas. Two other rivers, the Río Bairoa and Río Cagüitas, discharge into the Río Grande de Loíza just before it enters the reservoir. The combined mean annual runoff of the Río Grande de Loíza and the Río Gurabo for the 1960–2009 period of record is 323 Mm3. Flow from these streams constitutes about 89 percent of the total mean annual inflow of 364 Mm3 to the reservoir (U.S. Geological Survey, 2009). Detailed information about Lago Loíza reservoir structures, historical sediment accumulation, and a dredge conducted in 1999 are available in Soler-López and Gómez-Gómez (2005). During July 8–15, 2009, the U.S. Geological Survey (USGS) Caribbean Water Science Center (CWSC), in cooperation with PRASA, conducted a bathymetric survey of Lago Loíza to update the reservoir storage capacity and estimate the reservoir sedimentation rate by comparing the 2009 data with the previous 2004 bathymetric survey data. The purpose of this report is to document the methods used to update and present the results of the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since 2004.

Occupational safety and health practices among flower greenhouses workers from Alto Tietê region (Brazil).  

PubMed

In this preliminary study the occupational safety and health practices among flower greenhouses workers were evaluated. The study was carried out in the alto Tietê region, located at the Sao Paulo State, Brazil. Inadequate welfare facilities; poor pesticide storage, use and disposal conditions; use of highly toxic pesticides; lack of adequate data regarding pesticide use; and incorrect use and maintenance of PPE were observed in most of the visited greenhouses. These results suggest that, in greenhouses, workers may be at higher risk of pesticide exposure, due to many factors that can intensify the exposure such as the lack of control on reentry intervals after pesticide application. Specific regulations are needed to ensure better OSH practices on pesticide use and to improve working conditions in greenhouses, in order to deal with the peculiarities of greenhouse working environment. Some of the special requirements for greenhouses workers' protection are the establishment of ventilation criteria for restricted entry interval; clear reentry restrictions; and EPI for workers other than applicators that need to enter the greenhouse before expiring REI interval. Another important way to improve OSH practices among workers includes the distribution of simple guidelines on the dos and don'ts regarding OSH practices in greenhouses and extensively training interventions to change the perception of hazards and the behavior towards risk.

a Comparative Study of Alto Saxophone Reeds Through Spectral and Subjective Analyses.  

NASA Astrophysics Data System (ADS)

The purpose of this study was to analyze six brands of cane reeds and five brands of synthetic reeds to determine the differences in tone quality produced by each. Spectral analysis was used to determine the individual reed which conformed most closely to the average profile of each brand. A panel of seven saxophone performers then presented their opinions of the each reed's tone quality upon hearing a live performance of an excerpt from Eugene Bozza's Aria for alto saxophone and piano performed on the reeds most representative of each brand. The evaluation form used by the judges included ten sets of bipolar adjectives: good-bad, harmonious-dissonant, clean-dirty, light-dark, pleasurable-painful, beautiful-ugly, strong-weak, complex -simple, masculine-feminine, and interesting-boring. The results indicated that the primary factors influencing the tone quality of a given reed were the strength of the overtones present regardless of their order and the dominance of either the fundamental or the first overtone. Although professional musicians normally hand-select their reeds for performance, this research based on both spectral and subjective analyses provides clear evidence for both musicians and music educators to refine and improve their reed selection process.

Ethnobotanical notes about some uses of medicinal plants in Alto Tirreno Cosentino area (Calabria, Southern Italy)  

PubMed Central

Background The present paper contributes to enrich the ethnobotanical knowledge of Calabria region (Southern Italy). Research was carried out in Alto Tirreno Cosentino, a small area lying between the Tyrrhenian coast and the Pollino National Park. In the area studied medicinal plants still play a small role among farmers, shepherds and other people who live far from villages and built-up areas. Methods Information was collected by interviewing native people, mainly elderly – engaged in farming and stock-raising activities – and housewives. The plants collected, indicated by the locals, have been identified according to "Flora d'Italia". The exsiccata vouchers are preserved in the authors' own herbaria. Results 52 medicinal species belonging to 35 families are listed in this article. The family, botanical and vernacular name, part of the plant used and respective manipulation are reported there and, when present, similar or identical uses in different parts of Calabria or other Italian regions are also indicated. Conclusion Labiatae, Rosaceae and Leguminosae are the families most frequently present, whilst Compositae and Brassicaceae are almost absent. The uses of the recorded species relate to minor ailments, mainly those of the skin (15 species), respiratory apparatus diseases (11), toothache, decay etc. (10) and rheumatic pains (8). The easy availability of these remedies provides a quick way of curing various minor complaints such as tooth-ache, belly and rheumatic pain and headaches and can also serve as first aid as cicatrizing, lenitive, haemostatic agents etc. The role in veterinary medicine is, on the contrary, more important: sores, ulcers, tinea, dermatitis, gangrenous wounds of cattle, and even respiratory ailments are usually cured by resort to plants.

Fish mercury concentration in the Alto Pantanal, Brazil: influence of season and water parameters.  

PubMed

The tropical flood plain Pantanal is one of the world's largest wetlands and a wildlife sanctuary. Mercury (Hg) emissions from some upstream gold mining areas and recent findings of high natural Hg levels in tropical oxisols motivated studies on the Hg cycle in the Pantanal. A survey was made on total Hg in the most consumed piscivorous fish species from rivers and floodplain lakes in the north (Cáceres and Barão de Melgaço) and in the south part of Alto Pantanal (around the confluence of the Cuiabá and Paraguai rivers). Samples were collected in both the rainy and dry seasons (March and August 1998) and included piranha (Serrasalmus spp.), and catfish (Pseudoplatystoma coruscans, pintado, and Pseudoplatystoma fasciatum, cachara or surubim). There was only a small spatial variation in Hg concentration of the 185 analyzed fish samples from the 200 x 200 km large investigation area, and 90% contained total Hg concentration below the safety limit for regular fish consumption (500 ng g(-1)). Concentration above this limit was found in both Pseudoplatystoma and Serrasalmus samples from the Baia Siá Mariana, the only acid soft-water lake included in this study, during both the rainy and dry seasons. Concentration above this limit was also found in fish outside Baia Siá Mariana during the dry season, especially in Rio Cuiabá in the region of Barão de Melgaço. The seasonal effect may be connected with decreasing water volumes and changing habitat during the dry season. The results indicate that fertile women should restrict their consumption of piscivorous fishes from the Rio Cuiabá basin during the dry season. Measures should be implanted to avoid a further deterioration of fish Hg levels. PMID:11036973

Biodiversity of Archaea and floral of two inland saltern ecosystems in the Alto Vinalop? Valley, Spain  

PubMed Central

Background The extraction of salt from seawater by means of coastal solar salterns is a very well-described process. Moreover, the characterization of these environments from ecological, biochemical and microbiological perspectives has become a key focus for many research groups all over the world over the last 20 years. In countries such as Spain, there are several examples of coastal solar salterns (mainly on the Mediterranean coast) and inland solar salterns, from which sodium chloride is obtained for human consumption. However, studies focused on the characterization of inland solar salterns are scarce and both the archaeal diversity and the plant communities inhabiting these environments remain poorly described. Results Two of the inland solar salterns (termed Redonda and Penalva), located in the Alto Vinalopó Valley (Alicante, Spain), were characterized regarding their geological and physico-chemical characteristics and their archaeal and botanical biodiversity. A preliminary eukaryotic diversity survey was also performed using saline water. The chemical characterization of the brine has revealed that the salted groundwater extracted to fill these inland solar salterns is thalassohaline. The plant communities living in this environment are dominated by Sarcocornia fruticosa (L.) A.J. Scott, Arthrocnemum macrostachyum (Moris) K. Koch, Suaeda vera Forsk. ex Gmelin (Amaranthaceae) and several species of Limonium (Mill) and Tamarix (L). Archaeal diversity was analyzed and compared by polymerase chain reaction (PCR)-based molecular phylogenetic techniques. Most of the sequences recovered from environmental DNA samples are affiliated with haloarchaeal genera such as Haloarcula, Halorubrum, Haloquadratum and Halobacterium, and with an unclassified member of the Halobacteriaceae. The eukaryote Dunaliella was also present in the samples. Conclusions To our knowledge, this study constitutes the first analysis centered on inland solar salterns located in the southeastern region of Spain. The results obtained revealed that the salt deposits of this region have marine origins. Plant communities typical of salt marshes are present in this ecosystem and members of the Halobacteriaceae family can be easily detected in the microbial populations of these habitats. Possible origins of the haloarchaea detected in this study are discussed. PMID:20942947

4D modelling of the Alto Tiberina Fault system (Northern Apennines, Italy)  

NASA Astrophysics Data System (ADS)

The Alto Tiberina Fault (ATF) in the Northern Apennines of Italy is a low-angle normal fault dipping to the East and accommodating up to 10 km of extension. The fault is ~70 km long and is the detachment for the SW-dipping Gubbio normal fault. The ATF fault system has been dramatically exhumed and the ATF footwall has evolved in a horst bounded to the east by ATF synthetic faults and to the west by the Corciano west-dipping normal fault. The fault has been widely studied over the last years in order to understand its mechanical behaviour, its present-day deformation rate and its seismological role. By using a wide data-set including subsurface data (seismic reflection profiles and boreholes) and surface geological data (new maps of the CARG project of Italy), we have reconstructed the 3D geometry of both the fault and of the main lithostratigraphic boundaries at the fault hanging-wall and foot-wall. The CARG map data were integrated by local observations and mapping using mobile GIS software (BeeGIS) and Android app (Geopaparazzi). Surface data were combined with seismic reflection profiles and wells interpretation and other data from available literature. The large amount of information were combined in MOVE software (Midland Valley Exploration ltd). Our reconstruction allows to i) build up a three-dimensional geological model of the subsurface including the main faults and lithostratigraphic boundaries; ii) identify a set of east-west trending faults the role of which was previously underestimated; iii) test a 3D-restoration of extension for the visualization of the time evolution and for the validation of the structural reconstruction. The restored structures are the main normal faults in the region. The sequential restoration was performed by taking into account the timing of deformation as derived from the literature. The model was sequentially restored according to the following chronological order from the latest to the oldest: 1a) last deformational event along Gubbio Normal Fault on ATF coeval with 1b) latest event along Corciano fault and 2) ATF detachment fault activity. The resulting maximum values of displacements has been calculated as: 1a) about 2300m with a throw of about 1600m (measured in the 3D model on the top of Carbonates surfaces cut off); 1b) about 1900m for the slip and 2900m for the throw (measured along this fault both on the top of Carbonates as on acoustic Basement cut off); 2) 8 km of maximum extension measured between Umbertide e Citta' di Castello and progressively decreases toward NW and SW.

Guanaco traces and hunting strategies at Alto Patache North Chilean fog oasis  

NASA Astrophysics Data System (ADS)

1. In foregoing Fog Conferences, some of us have made explicit the rich botanic and faunistic inventory to be found at this Chilean Fog site. This was specially apparent under strong ENSO conditions, as it happened in 1997/98 in the area. Among the mammal biggest species represented, the guanaco (Lama guanicoe Müller) merits special mention. Clear traces of their presence and eventual hunting and slaughtering by primitive populations have survived until present times. Among them, the myriads of guanaco trails still covering practically all the slopes along the foggy area, close to the sea, and their wollowing and defecating places are found. Also, although less studied, plant eating traces left behind by roaming camelids can be seen. 2. Guanaco hunting traces still visible at Alto Patache can be portrayed differently through : A) Analysis of lithic artifacts used as arms in hunting operations; B) Botanic response to animal attack; C) Examination of topographic traits used by primitive man in guanaco hunting strategies. A. Hundreds of lithic instruments made of stone, were abandoned by hunters in situ, some of them were intact, some fragmented, which would demonstrate a direct relationship with hunting and slaughtering, and also their elaboration in workshops at place. Lithic points, scrapers and knives were found at places specially apt for hunting or slaughtering activities. Total isolation of the mountain fog site previous to our arrival in 1996, favoured their conservation at place. B. Careful observation of some local plants showed clear traces of guanaco feeding habits. As a proof thereof, old cactus of the species Eulychnia iquiquensis show in their basal portions clear signals in the forms of scars, caused by the eating by guanacos. Guanaco faeces were found at the foot of Ephedra plants. Many dead Stipa ichu plants (Gramineae), in different areas of the oasis provide evidence of cutting close to their basis, caused by sharp guanaco tooth under severe food scarcity. C. Special lookouts located at high places offering clear visibility were used by hunters. Some were built up, some others consisted of natural stone arrangements. The same can be said for the wollowing places, located in plains with loose or sandy soils. Pictures showing different artifacts, plants or topographic traits used, will be presented here as evidence of guanaco hunting activity at place.

Alto Patache fog oasis in the Atacama Desert: Geographical basis for a sustainable development program  

NASA Astrophysics Data System (ADS)

Alto Patache coastal fog oasis is a protected area located south of Iquique, Northern Chile, being presently in charge of the Atacama Desert Center (ADC) research group of the Pontificia Universidad Católica de Chile, since 1997. On 2007, the Chilean Government bestowed a piece of land stretch covering 1,114 hectares to ADC scientific group for scientific research, ecosystem protection and environmental education. This oasis has been recently studied from different points of view: climate, biogeography, fog collection, geomorphology, soil survey and land use planning, plant distribution, conservation and archaeology. During 2009, a study of the geographical basis to elaborate a general management plan was undertaken to collect information to fulfill our planned out objectives. Through this study, georreferenciated strategic information was compiled to evaluate future actions conducting to a sustainable development within the protected area. This information was translated into thematic maps showing the spatial distribution of variables like: climate, geology, geomorphology, soils, vegetation, fauna, archaeological sites and management zones. The methodology used is the analysis of satellite imagery, using GPS by creating a cartographic Data Base incorporated in GIS. Results show that the area starts at the littoral plain, ranging from 500 m to 2.000 m, being continued in parts by a piedmont intercepted by a very abrupt mega-cliff, or hectares of climbing sand dunes leading to a short high plateau limited by a soft hilly area to the East. Two soil types are characteristic: Entisols (Torriorthent) covering the coastal beach sediments, and Aridisols along the cliff and adjacent hills. Vegetation consists not only of a very rich lichen cover, but also of endangered vascular species associations constituting a very fragile sub-tropical coastal desert community, such as Eulychnia, Cumulopuntia, Eriosyce cacti, and Lycium - Nolana- Ephedra communities. Fog oasis stretches from 500/600 m. to 900 m high. Biogeogeographical contrasts between the foggy section, the areas located below the stratocumulus cloud influence (fog), and the higher hills, show interesting results for the understanding of the area complexity. Future human activities at place should be restricted to scientific studies, environmental education and specialized tourism. Some zones, like lichen prairies, should be totally closed for visitors. Protected area management program should be mainly focused in biome conservation and natural resources restauration.

Low-Cost Sensor Network for Stream Flow Monitoring in the Alto Beni Region of Bolivia  

NASA Astrophysics Data System (ADS)

Lack of data is a persistent problem in hydrology and other field work in developing countries. Low cost monitoring devices allow investigators to maximize spatial coverage on a limited budget, as well as to minimize the financial risk of loss of instruments placed in vulnerable locations. This work contributes to an ongoing project to evaluate the sustainability of discharge from springs supplying gravity-fed potable water systems in the Alto Beni region of Bolivia where land use is rapidly changing from forest to agriculture. The approach is to estimate ground water recharge as a function of land use variables using a water balance model in several representative watersheds. Monthly stream discharge is currently estimated using monthly manual measurements of water level by a local technician. Continuous water level measurements will allow an improved estimate of the cumulative discharge, and generate data on statistical distribution of daily flow that may be useful to estimate discharge in similar, ungaged watersheds. Continuous water level measurements, along with available precipitation data, will allow analysis and comparison of the response of watersheds to individual precipitation events as a function of land use variables. We assembled a low cost level logging system for stream flow monitoring that measures and records distance up to 6 m to the nearest 25 mm every ten minutes, and runs for a month on six rechargeable AA batteries. The system consists of a sonic range finder sensor (MaxSonar-EZ2, Maxbotix Inc., Baxter, MN, 30), a temperature sensor (MCP9701, Microchip Technology Inc., Chandler, AZ, 0.25), and a datalogger (Hobo U12, Onset Computer Corp., Pocasset, MA, 104) along with a weather-resistant enclosure and common items for a total cost of 230 per unit. The level loggers were attached to bridges over three subject streams. A local technician visits the sites monthly to download data, replace the rechargeable batteries, and take a manual water level measurement. Simultaneous recording of temperature is necessary to correct the distance measurement for the temperature dependence of the speed of sound in air. We report the data processing, temperature correction procedure, and performance of the system relative to manual measurements and discuss suitability of the system for hydrological applications in other settings.

Liquefaction Hazard Maps for Three Earthquake Scenarios for the Communities of San Jose, Campbell, Cupertino, Los Altos, Los Gatos, Milpitas, Mountain View, Palo Alto, Santa Clara, Saratoga, and Sunnyvale, Northern Santa Clara County, California  

USGS Publications Warehouse

Maps showing the probability of surface manifestations of liquefaction in the northern Santa Clara Valley were prepared with liquefaction probability curves. The area includes the communities of San Jose, Campbell, Cupertino, Los Altos, Los Gatos Milpitas, Mountain View, Palo Alto, Santa Clara, Saratoga, and Sunnyvale. The probability curves were based on complementary cumulative frequency distributions of the liquefaction potential index (LPI) for surficial geologic units in the study area. LPI values were computed with extensive cone penetration test soundings. Maps were developed for three earthquake scenarios, an M7.8 on the San Andreas Fault comparable to the 1906 event, an M6.7 on the Hayward Fault comparable to the 1868 event, and an M6.9 on the Calaveras Fault. Ground motions were estimated with the Boore and Atkinson (2008) attenuation relation. Liquefaction is predicted for all three events in young Holocene levee deposits along the major creeks. Liquefaction probabilities are highest for the M7.8 earthquake, ranging from 0.33 to 0.37 if a 1.5-m deep water table is assumed, and 0.10 to 0.14 if a 5-m deep water table is assumed. Liquefaction probabilities of the other surficial geologic units are less than 0.05. Probabilities for the scenario earthquakes are generally consistent with observations during historical earthquakes.

Advanced interpretation of ground motion using Persistent Scatterer Interferometry technique: the Alto Guadalentín Basin (Spain) case of study  

NASA Astrophysics Data System (ADS)

Subsidence related to fluid withdrawal has occurred in numerous regions of the world. The phenomena is an important hazard closely related to the development of urban areas. The analysis of the deformations requires an extensive and continuous spatial and temporal monitoring to prevent the negative effects of such risks on structures and infrastructures. Deformation measurements are fundamental in order to identify the affected area extension, to evaluate the temporal evolution of deformation velocities and to identify the main control mechanisms. Differential SAR interferometry represents an advanced remote sensing tool, which can map displacements at very high spatial resolution. The Persistent Scatterer Interferometry (PSI) technique is a class of SAR interferometry that uses point-wise radar targets (PS) on the ground whose phase is not interested by temporal and geometrical decorrelation. This technique generates starting from a set of images two main products: the displacement rate along line of sight (LOS) of single PS; and the LOS displacement time series of individual PS. In this work SAR data with different spatio-temporal resolution were used to study the displacements that occur from 1992 to 2012 in the Alto Guadalentin Basin (southern Spain), where is located the city of Lorca The area is affected by the highest rate of subsidence measured in Europe (>10 cm/yr-1) related to long-term exploitation of the aquifer (González et al. 2011). The objectives of the work were 1) to analyse land subsidence evolution over a 20-year period with PSI technique; 2) to compare the spatial and temporal resolution of SAR data acquired by different sensors, 3) to investigate the causes that could explain this land motion. The SAR data have been obtained with ERS-1/2 & ENVISAT (1992-2007), ALOS PALSAR (2007-2010) and COSMO-SkyMed (2011-2012) images, processed with the Stable Point Network (SPN) technique. The PSI data obtained from different satellite from 1992 to 2012 were compared with some predisposing and trigger factors as geological units, isobaths of Plio-Quaternary filling, soft soil thickness and piezometric level. The PSI data were compared with measurement obtained by two GPS station located near the Lorca city: the value of deformation detected by satellites and ground-based tools are well correlated. The results are the following: a) the subsidence processes are related to soft soil thickness distribution; b) land subsidence rates shows that the area interested by the higher value is the same over the monitored period, a deceleration rate of subsidence has been recorded during the period 2011- 2012; c) the deformation rates are not correlated with the piezometric level trend, a delay time between piezometric level variations and ground deformations is evident.

Lack of identification of Flaviviruses in oral and cloacal swabs from long- and short-distance migratory birds in Trentino-Alto Adige (North-eastern Italy)  

PubMed Central

Background West Nile virus (WNV) and Usutu virus (USUV), both belonging to the genus Flavivirus, are emerging in Italy as important human and animal pathogens. Migratory birds are involved in the spread of Flaviviruses over long distances, particularly from Africa to Europe. Once introduced, these viruses can be further be dispersed by short-distance migratory and resident bird species. Thus far, there is still a considerable knowledge gap on the role played by different bird species in the ecology and transmission mechanisms of these viruses. The Region of Trentino-Alto Adige (north-eastern Italy) is located on the migratory route of many of the short- and long-distance migratory birds that cross the Alps, connecting northern Europe and western Asia with southern Europe and Africa. Until now, only a silent circulation of WNV and USUV within the territory of the Province of Trento has been confirmed by serological screening, whilst no cases of infected humans or animals have so far been reported. However, continuous spillover events of both viruses have been reported in neighbouring Regions. The aim of this study was to monitor the circulation of WNV and USUV in Trentino-Alto Adige, in order to detect if active virus shedding occurs in migratory birds captured during their seasonal movements and to evaluate the role that different bird species could play in the spreading of these viruses. Methods We carried out a biomolecular survey on oral and cloacal swabs collected from migratory birds during seasonal migrations. Birds belonging to 18 transaharian and 21 intrapaleartic species were examined during spring (n?=?176) and autumn (n?=?146), and were tested using a generic nested-PCR. Results All samples tested negative for Flaviviruses. The possible causes of unapparent shedding, along with ecological and epidemiological implications are discussed. Conclusions The lack of detection of active virus shedding in these bird species does not exclude the circulation of these viruses within the Trentino-Alto Adige region, as reported in previous studies. The possible ecological implications are discussed. PMID:24119320

Water and Energy Savings using Demand Hot Water Recirculating Systems in Residential Homes: A Case Study of Five Homes in Palo Alto, California  

SciTech Connect

This report summarizes a preliminary study aimed at estimating the potential of saving potable water, (and the electrical energy used to heat it), that is presently lost directly to the drain while occupants wait for hot water to arrive at the faucet (point of use). Data were collected from five single-family homes in Palo Alto, California. Despite the small sample size in this study, the results make a compelling case for retrofitting homes with hot water recirculation systems to eliminate unnecessary wastage of water at the point of use. Technical as well as behavioral and attitudinal changes towards water conservation are necessary for a fulfilling and successful conservation effort. This report focuses on the technical issues, but behavioral issues are also noted, which may be factored into future studies involving local and state governments and utility companies.

An investigation of ground-water recharge by injection in the Palo Alto Baylands, California : hydraulic and chemical interactions; final report  

USGS Publications Warehouse

The U.S. Geological Survey, in cooperation with the Santa Clara Valley Water District, has completed a study of ground-water recharge by injection in the Palo Alto baylands along San Francisco Bay, California. Selected wells within the Water District 's injection-extraction network were monitored to determine hydraulic and chemical interactions affecting well-field operation. The well field was installed to prevent and eliminate saline contamination in the local shallow aquifer system. The primary focus of this study is on factors that affect injection efficiency, specifically well and aquifer clogging. Mixing and break-through curves for major chemical constituents indicate ion exchange, adsorption, and dissolution reactions. Freshwater breakthrough was detected in water-level data, which reflected fluid-density change as well as head buildup. Dissolution of calcium carbonate caused by dilution of saline ground water probably accounts for an apparent increase in specific capacity possibly related to improved aquifer permeability. Adsorption evidently removed trace elements during passage of injected water through the aquifer. In terms of hydraulic and chemical compatibility, the well field is a viable system for ground-water recharge. Aquifer heterogeneity and operational constraints reduce the efficiency of the system. Efficiency may be maximized by careful attention to extraction distribution and quantity and to injection distribution, quantity, and water quality. (USGS)

Mathiasite-loveringite and priderite in mantle xenoliths from the Alto Paranaíba Igneous Province, Brazil: genesis and constraints on mantle metasomatism  

NASA Astrophysics Data System (ADS)

Alkali-bearing Ti oxides were identified in mantle xenoliths enclosed in kimberlite-like rocks from Limeira 1 alkaline intrusion from the Alto Paranaíba Igneous Province, southeastern Brazil. The metasomatic mineral assemblages include mathiasite-loveringite and priderite associated with clinopyroxene, phlogopite, ilmenite and rutile. Mathiasite-loveringite (55-60 wt.% TiO2; 5.2-6.7 wt.% ZrO2) occurs in peridotite xenoliths rimming chromite (˜50 wt.% Cr2O3) and subordinate ilmenite (12-13.4 wt.% MgO) in double reaction rim coronas. Priderite (Ba/(K+Ba)< 0.05) occurs in phlogopite-rich xenoliths as lamellae within Mg-ilmenite (8.4-9.8 wt.% MgO) or as intergrowths in rutile crystals that may be included in sagenitic phlogopite. Mathiasite-loveringite was formed by reaction of peridotite primary minerals with alkaline melts. The priderite was formed by reaction of peridotite minerals with ultrapotassic melts. Disequilibrium textures and chemical zoning of associated minerals suggest that the metasomatic reactions responsible for the formation of the alkali-bearing Ti oxides took place shortly prior the entrainment of the xenoliths in the host magma, and is not connected to old (Proterozoic) mantle enrichment events.

El Universo a alto redshift  

NASA Astrophysics Data System (ADS)

The Universe we see today is the result of structures and galaxies that have been evolving since earlier times. Looking the evolution of the galaxy population at z ˜ 1 has emphasized the important role played by high redshift data. This is the case of the morphology - density relationship, where the morphological type of galaxies in distant clusters has given us a clear vision of evolutionary processes, partly led by environmental effects. I review part of the data available at high redshifts that are fundamental today to check the validity of galaxy formation models in reproducing local and basic galaxy properties. Briefly, I will comment about high redshift studies, a still little explored portion of the Universe, and the current strategies that allow us the study. In this sense, the epoch of reionization is essential for understanding the formation of structures because it is the phase where the first protogalaxies were formed, creating stars and enriching the intergalactic medium. Because of the great distances involved in these studies, gamma-ray bursts, quasars and Lyman-? galaxies are the best tools to study these earlier times. FULL TEXT IN SPANISH

Construction of a manual of work processes and techniques from Centro de Dispensação de Medicamentos de Alto Custo (CEDMAC), Hospital de Clínicas, Unicamp.  

PubMed

The Centers for High Cost Medication (Centros de Medicação de Alto Custo, CEDMAC), Health Department, São Paulo were instituted by project in partnership with the Clinical Hospital of the Faculty of Medicine, USP, sponsored by the Foundation for Research Support of the State of São Paulo (Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP) aimed at the formation of a statewide network for comprehensive care of patients referred for use of immunobiological agents in rheumatological diseases. The CEDMAC of Hospital de Clínicas, Universidade Estadual de Campinas (HC-Unicamp), implemented by the Division of Rheumatology, Faculty of Medical Sciences, identified the need for standardization of the multidisciplinary team conducts, in face of the specificity of care conducts, verifying the importance of describing, in manual format, their operational and technical processes. The aim of this study is to present the methodology applied to the elaboration of the CEDMAC/HC-Unicamp Manual as an institutional tool, with the aim of offering the best assistance and administrative quality. In the methodology for preparing the manuals at HC-Unicamp since 2008, the premise was to obtain a document that is participatory, multidisciplinary, focused on work processes integrated with institutional rules, with objective and didactic descriptions, in a standardized format and with electronic dissemination. The CEDMAC/HC-Unicamp Manual was elaborated in 10 months, with involvement of the entire multidisciplinary team, with 19 chapters on work processes and techniques, in addition to those concerning the organizational structure and its annexes. Published in the electronic portal of HC Manuals in July 2012 as an e-Book (ISBN 978-85-63274-17-5), the manual has been a valuable instrument in guiding professionals in healthcare, teaching and research activities.

Relationship between spatial variations in active creep and large magnitude hanging wall earthquakes associated with the Alto Tiberina low angle normal fault, central Italy.  

NASA Astrophysics Data System (ADS)

The Alto Tiberina fault (ATF) in central Italy is a rare instance of a low angle normal fault that appears to be actively creeping at shallow to mid-crustal depths. While conventional Anderson earthquake mechanics dictate that these faults should lock up under extension, recent studies using GPS velocity data and simple fault models suggest that the ATF accommodates slip by aseismic creep below ~4 km depth in the latitude range of 43.2 N to 43.5 N. This creeping section of the ATF is well imaged and there are no instrumentally recorded large magnitude earthquakes in the hanging wall. There is no evidence for active fault creep north and south of the creeping section where large hanging wall earthquakes have occurred. We use geodetically determined images of fault creep and earthquake focal mechanisms data to explore the stress transfer relationships between the creeping section of the ATF and adjacent portions of the fault zone, which appear to be locked. In one interpretation, hanging wall earthquakes occur as a result of strain accumulation caused by variations in creep on the low angle normal fault. An alternative explanation is that creep on the low angle fault has been inhibited in the vicinity of the large magnitude hanging wall earthquakes. These spatial relationships notwithstanding, the resolution of the imaged pattern of creep is relatively low. A borehole strainmeter network would provide unprecedented temporal resolution of aseismic creep transients that would help to evaluate the possible relationships between hanging wall stress accumulation and stress sensitive creep. The combination of modeling and seismic/geodetic monitoring with a new borehole strainmeter array would also help to decipher the fault structure, earthquake mechanisms, and seismic risk in a populated area.

The incidence of bar-like kinematic flows in the first data release of the Calar Alto Legacy Integral Field spectroscopy Area Survey  

NASA Astrophysics Data System (ADS)

Kinematic models of Halpha velocity fields for galaxies in the Calar Alto Legacy Integral Field Area Survey (CALIFA) first data release (DR1) are determined in order to constrain the incidence of bar-like, or bisymmetric, flows therein. Of the 100 CALIFA DR1 galaxies, 47 are found to have suitable inclinations and sufficient Ha emission for kinematic modelling. This modelling is carried out using the publicly available code DiskFit, which was designed to detect non-circular flows. A routine is written to automate the successive application of DiskFit to the 47/100 suitable CALIFA galaxies, and rotation only, bisymmetric, radial and warp kinematic models are applied to each. Valid DiskFit results are returned for 37/47 of the galaxies. The remaining 10/47 had kinematic inclinations outside the adopted range or exhibited signs of interactions. The optimal model for each system is determined by examining the quality of the returned disk geometry and kinematics, the statistical significance of detected non-circular flows, and the pattern of data - model residuals. DiskFit is found to reliably determine the disk geometry regardless of the kinematic model selected. The chi-square test used to evaluate the significance of non-circular flows is accurate for 24/29 (83%) of the modelled galaxies containing sufficient Ha to search for non-circular flows, suggesting its utility in automating the model determination process for future surveys. In 4/23 (17%) of the modelled galaxies classified as either photometrically barred (B) or unbarred (A), the photometric classification belies a different kinematic classification. This suggests that samples of galaxies selected using photometric bar classifications could be systematically contaminated.

Climate change and development impacts on the sustainability of spring-fed water supply systems in the Alto Beni region of Bolivia  

NASA Astrophysics Data System (ADS)

SummaryIn the Alto Beni region of Bolivia, as in other locations of the developing world, gravity-fed water supply systems provide a significant portion of domestic water needs. However, sustainability of these sources depends on whether discharge can be sustained to accommodate future water needs. There is a perception that agricultural expansion in the region is resulting in reduced spring discharge. To investigate this claim, we incorporate low-cost field methods for hydrologic data collection and evaluate two satellite-derived precipitation data products (CMORPH and TRMM-3B42) for input to a hydrological model used to predict recharge rates in eleven watersheds under scenarios of climate change and agricultural expansion. The stressors on the local water supply examined in this study are changes in land use and climate, along with increases in population and consumption, and improvements in water and sanitation coverage. Although predicted changes in runoff range from -69% to +137%, depending on the climate and land use scenario, recharge is predicted to decrease under all scenarios (by 28% to nearly 100%) between the periods of 1970-1999 and 2070-2099. The predicted impacts from climate change are considerably larger than those from agricultural expansion, calling into question local perceptions that spring flow has declined because of changes in land use from agricultural growth. The ratio of water use to availability under most scenarios of climate change and water and sanitation service expansion suggests that use of groundwater is sustainable in the region when considering the entire recharge to the watersheds. However, the small recharge areas of the springs may result in insufficient recharge to support planned water and sanitation expansion unless new water supplies are developed.

South San Francisco Bay tidal marsh vegetation and elevation surveys-Corkscrew Marsh, Bird Island, and Palo Alto Baylands, California, 1983  

USGS Publications Warehouse

Changes in the topography and ecology of the San Francisco Bay Estuary ('Estuary') during the past 200 years have resulted in the loss of nearly 80 percent of the historical salt marsh in the region. Currently, numerous projects are being undertaken by federal, state, and local governments in an attempt to restore wetland habitat and ecosystem function at a number of locations within the Estuary. Much information is needed concerning the historical topographic and ecologic characteristics of the Estuary to facilitate these restoration efforts. This report presents previously unpublished vegetation and elevation data collected in 1983 by the California State Lands Commission at Corkscrew marsh, Bird Island, and Palo Alto Baylands, all located in South San Francisco Bay. These precise and detailed elevation and plant surveys represent a snapshot of South Bay flora before invasion by the Atlantic smooth cordgrass, Spartina alterniflora. Such precise elevation data are rare for relatively undisturbed marshes in the San Francisco Bay; publication of these historical data may facilitate wetland restoration efforts. Marsh-surface and tidal-channel elevations were determined at a total of 962 stations by differential leveling to established tidal benchmark stations at each site and referenced to Mean Lower Low Water (MLLW) relative to the National Tidal Datum Epoch (1960-78). In addition, presence or absence of nine salt marsh species, percentage plant cover, and percentage bare soil were recorded for 1-square meter quadrats at 648 stations where elevations were determined. Collectively, over the three sites, salt marsh vegetation ranged in elevation from 0.98 to 2.94 m above MLLW. S. foliosa and Salicornia virginica were the most frequently observed plant species. Atriplex patula, Deschampsia cespitosa, and Limonium californicum were each recorded at only one of the three sites.

Implications of agricultural land use for sustainability of gravity fed water distribution systems relying on natural springs in the Alto Beni Region of Bolivia  

NASA Astrophysics Data System (ADS)

Gravity-fed distribution systems from natural springs are frequently used as a method for providing drinking water to developing communities throughout the world. They are seen as an appropriate technology for their relatively simple operation and maintenance requirements. Spring discharge, however, depends on recharge rates in the spring’s catchment area, and the storage and distribution system must be designed with this potentially non-stationary input in mind. The dependence of recharge rates on land use varies with slope, soil type, vegetation, and humidity of the region. Therefore, in many developing communities where there is little watershed monitoring, little is known about how changes in land use may result in variability or long term trends in spring flow. Appropriate, low cost methods that can be carried out with local knowledge and labor are required for assessing the sustainability of natural springs as sources of drinking water in local settings, especially where land use is rapidly changing. We present results from an analysis evaluating the sustainability of discharge from springs supplying gravity-fed water systems in the Alto Beni region of Bolivia, where land use is rapidly changing from forest to agriculture. This analysis is accomplished using appropriate data collection methods with the assistance of local technicians and could be readily transferred to other watershed studies in developing communities. The study involves eleven local watersheds with varying percentage of land use devoted to agriculture area. Preliminary results show that discharge variability is higher in watersheds with more agriculture, suggesting that recharge rates in the region decrease with increased land area devoted to agriculture.

Magnetic fabric of Pleistocene continental clays from the hanging-wall of a low-angle normal fault (Alto Tiberina Fault, Italy)  

NASA Astrophysics Data System (ADS)

Anisotropy of magnetic susceptibility (AMS) represents a valuable strain proxy able to detect subtle strain effects in very weakly deformed sediments, since the AMS ellipsoid compares to the strain ellipsoid (Hrouda 1982; Borradaile 1988; Tarling & Hrouda 1993; Borradaile & Henry, 1997; Borradaile & Jackson, 2004). During the last decades a large number of AMS studies have documented that in compressive tectonic setting the maximum susceptibility axes (i.e. the magnetic lineations) are parallel to fold axes (and thrust faults) and local bedding strikes, while in extensional regimes (Sagnotti et al., 1994; Mattei et al., 1999; Cifelli et al., 2004) they are perpendicular to the normal faults and, thus, parallel to the strata dip directions. One of the most striking active structures of the northern Apennines is represented by the Alto Tiberina Fault (ATF), a NE-dipping low-angle normal fault bounding the High Tiber Valley. The ATF is largely documented to represent a primary detachment of the Plio-Quaternary extensional tectonics affecting the Apennine belt. The long-lasting activity of the ATF produced 5 km of total displacement and up to 1200-m-thick basin infill of syntectonic, sandy-clayey continental succession. Thus, the AMS analysis of the sediments lying above the ATF represents a unique opportunity to document the strain field affecting the hanging-wall of low-angle normal faults. We collected 133 oriented cores at 13 different localities within the High Tiber Valley, and the AMS was measured in the paleomagnetic laboratory at the INGV (Rome, Italy) with a spinner Multi-Function Kappabridge. The AMS ellipsoids and their parameters resulted well defined at 12 sites. Most of the sites show a predominantly sedimentary fabric, while prolate ellipsoids at two sites are suggestive of a pervasive tectonic deformation. The magnetic lineation is well-developed and has a prevailing NNE direction. At seven sites the magnetic lineations are sub-parallel to local bed-strikes, implying that these sites probably underwent a ESE-directed compressive stress. Other lines of evidence (i.e. the AMS parameters) indicate that four more sites could have be affected by a similar compressive tectonics, whereas a clear extensional magnetic lineation is present at only one site, where the magnetic lineation is sub-parallel to the strata dip direction. Our results show geological evidence of compressive strain field affecting the sediments deposited on the hanging-wall of the ATF. The coexistence of compressional structures within an extensional tectonic domain leaded by a low-angle normal fault may have different causes: (i) arrangement of local folds with axes sub-parallel to the regional trend of the main fault, related to non-planarity of the detachment fault at depth and not to compressive events punctuating the Quaternary extensional phase, as previously proposed; (ii) the shallow effect related to roll-over of the hanging-wall in purely extensional tectonic settings, as already documented in the Basin and Range Province and by numerical modelling.

Detection of rickettsia parkeri from within Piura, Peru, and the first reported presence of Candidatus rickettsia andeanae in the tick Rhipicephalus sanguineus.  

PubMed

Domestic farm animals (n=145) were sampled for the presence of ectoparasites in northwestern Peru during March, 2008. Ninety domestic animals (62%) were positive for the presence of an ectoparasite(s) and produced a total collection of the following: 728 ticks [Amblyomma maculatum, Anocentor nitens, Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, and Otobius megnini], 12 lice (Haematopinus suis), and 3 fleas (Ctenocephalides felis). A Rickettsia genus-specific qPCR assay was performed on nucleic acid preparations of the collected ectoparasites that resulted in 5% (37/743, 35 ticks and 2 fleas) of the ectoparasites positive for the presence of Rickettsia. DNA from the positive individual ticks was tested with 2 other qPCR assays for the presence of the ompB gene in Candidatus Rickettsia andeanae or Rickettsia parkeri. Candidatus R. andeanae was found in 25 A. maculatum ticks and in two Rh. sanguineus ticks, whereas R. parkeri was detected in 6 A. maculatum ticks. Two A. maculatum were co-infected with both Candidatus R. andeanae and R. parkeri. Rickettsia felis was detected in 2 fleas, Ctenocephalides felis, by multilocus sequence typing of the 17-kD antigen and ompA genes. These findings expand the geographic range of R. parkeri to include Peru as well as expand the natural arthropod vector of Candidatus R. andeanae to include Rhipicephalus sanguineus. PMID:23488453

Near-Field Receiving Water Monitoring of Trace Metals and a Benthic Community Near the Palo Alto Regional Water Quality Control Plant in South San Francisco Bay, California: 2006  

USGS Publications Warehouse

Results reported herein include trace element concentrations in sediment and in the clam Macoma petalum (formerly reported as Macoma balthica (Cohen and Carlton 1995)), clam reproductive activity, and benthic macroinvertebrate community structure for a mudflat one kilometer south of the discharge of the Palo Alto Regional Water Quality Control Plant in South San Francisco Bay. This report includes data collected for the period January 2006 to December 2006, and extends a critical long-term biogeochemical record dating back to 1974. These data serve as the basis for the City of Palo Alto's Near-Field Receiving Water Monitoring Program, initiated in 1994. Metal concentrations in both sediments and clam tissue during 2006 were consistent with results observed since 1990. Most notably, copper and silver concentrations in sediment and clam tissue increased in the last year but the values remain well within range of past data. Other metals such as chromium, nickel, vanadium, and zinc remained relatively constant throughout the year except for maximum values generally occurring in winter months (January-March). Mercury levels in sediment and clam tissue were some of the lowest seen on record. Conversely, selenium concentrations reached a maximum level but soon returned to baseline levels. In all, metal concentrations in sediments and tissue remain within past findings. There are no obvious directional trends (increasing or decreasing). Analyses of the benthic-community structure of a mudflat in South San Francisco Bay over a 31-year period show that changes in the community have occurred concurrent with reduced concentrations of metals in the sediment and in the tissues of the biosentinel clam M. petalum from the same area. Analysis of the reproductive activity of M. petalum shows increases in reproductive activity concurrent with the decline in metal concentrations in the tissues of this organism. Reproductive activity is presently stable, with almost all animals initiating reproduction in the fall and spawning the following spring of most years. The community has shifted from being dominated by several opportunistic species to a community where the species are more similar in abundance, a pattern that suggests a more stable community that is subjected to less stress. In addition, two of the opportunistic species (Ampelisca abdita and Streblospio benedicti) that brood their young and live on the surface of the sediment in tubes, have shown a continual decline in dominance coincident with the decline in metals. Heteromastus filiformis, a subsurface polychaete worm that lives in the sediment, consumes sediment and organic particles residing in the sediment, and reproduces by laying their eggs on or in the sediment, has shown a concurrent increase in dominance. These changes in species dominance reflect a change in the community from one dominated by surface dwelling, brooding species to one with species with varying life history characteristics. For the first time since its invasion in 1986, the non-indigenous filter-feeding clam Corbula (Potamocorbula) amurensis has shown up in small, but persistent, numbers in the benthic community.

Relaciones hidrogeologicas y medioambientales entre el mar mediterraneo, El saladar y el acuifero de agua amarga (provincia de alicante). Incidencia de las explotaciones de las desaladoras de alicante I Y II Y medidas correctoras  

NASA Astrophysics Data System (ADS)

The Agua Amarga coastal aquifer, located in the south of Alicante province, has been subjected to successive anthropogenic actions: salt works activity (1925-1975) and water withdrawal to supply the Alicante I and II desalination plants (since 2003). These interventions have influenced the salinity and the flow regime. Due to the existence of a salt marsh of ecological interest linked to the aquifer, the 'Mancomunidad de los Canales del Taibilla' (agency responsible for the desalination plants) designed a piezometric network for monitoring piezometry and electrical conductivity (in operation since May 2008). Soil humidity and piezometrics levels have been recovered by means of a seawater pouring programme over the salt marsh (since December 2009),which represents the third anthropic intervention. In this memoria, we investigate the Agua Amarga coastal aquifer to develop a physical conceptual model. Firstly, the study area is characterized in relation to climatology, geology, geomorphology and hydrogeology, using published information, describing, in addition, the desalination plants catchment system. Next, based on hydrogeological studies prior to the start up of the desalination plants, the aquifer is characterized: type, lithology, hydraulic parameters, thickness, surface extension, etc. Water quantity relating to rainfall, water withdrawal and pourings over the salt marsh, have been integrated in conjunction with data from monthly piezometric campaigns. In adittion, in order to gain insight into the groundwater mixing processes, chemical and isotope analyses were carried out on meteoric water and groundwater samples taken at different locations. The results were used to elaborate a conceptual physical model and a water budget. As an extension tool to understand processes and assess aquifer management, a 3-D fluid-flow and solute-transport model is designed with SEAWAT. Also, the 2-D physical characterization of scenarios with seawater intrusion and salt flats is presented. Finally, after describing ecological values of the salt marsh, the effect of the seawater pouring programme on aquifer piezometry and salinity is studied, assessing the possibility of applying this pilot scheme to other scenarios.

Quasi 3D modeling of water flow in vadose zone and groundwater  

NASA Astrophysics Data System (ADS)

SummaryThe complexity of subsurface flow systems calls for a variety of concepts leading to the multiplicity of simplified flow models. One habitual simplification is based on the assumption that lateral flow and transport in unsaturated zone are not significant unless the capillary fringe is involved. In such cases the flow and transport in the unsaturated zone above groundwater level can be simulated as a 1D phenomenon, whereas the flow and transport through groundwater are viewed as 2D or 3D phenomena. A new approach for a numerical scheme for 3D variably saturated flow using quasi 3D Richards' equation and finite difference scheme is presented. The corresponding numerical algorithm and the QUASI-3D computer code were developed. Results of the groundwater level simulations were compared with transient laboratory experimental data for 2D data constant-flux infiltration, quasi-3D HYDRUS-MODFLOW numerical model and a FULL-3D numerical model using Richards' equation. Hypothetical 3D examples of infiltration, pumping and groundwater mound dissipation for different spatial-time scales are presented. Water flow simulation for the Alto Piura aquifer (Peru) demonstrates the QUASI-3D model application at the regional scale. Computationally the QUASI-3D code was found to be more efficient by an order of 10-300%, while being accurate with respect to the benchmark fully 3D variable saturation code, when the capillary fringe was considered.

The Poor Survival among Pulmonary Tuberculosis Patients in Chiapas, Mexico: The Case of Los Altos Region  

PubMed Central

Objective. To analyse survival in patients with pulmonary tuberculosis (PTB) and factors associated with such survival. Design. Study of a cohort of patients aged over 14 years diagnosed with PTB from January 1, 1998 to July 31, 2005. During 2004–2006 a home visit was made to each patient and, during 2008-2009, they were visited again. During these visits a follow-up interview was administered; when the patient had died, a verbal autopsy was conducted with family members. Statistical analysis consisted of survival tests, Kaplan-Meier log-rank test and Cox regression. Results. Of 305 studied patients, 68 had died due to PTB by the time of the first evaluation, 237 were followed-up for a second evaluation, and 10 of them had died of PTB. According to the Cox regression, age (over 45 years) and treatment duration (under six months) were associated with a poorer survival. When treatment duration was excluded, the association between poorer survival with age persisted, whereas with having been treated via DOTS strategy, was barely significant. Conclusions. In the studied area it is necessary that patients receive a complete treatment scheme, and to give priority to patients aged over 45 years. PMID:22701170

The Wendelstein Calar Alto Pixellensing Project (WeCAPP): the M 31 nova catalogue  

NASA Astrophysics Data System (ADS)

We present light curves from the novae detected in the long-term, M 31-monitoring WeCAPP project. The goal of WeCAPP is to constrain the compact dark matter fraction of the M 31 halo with microlensing observations. As a by product we detected 91 novae benefiting from the high cadence and highly sensitive difference imaging technique required for pixel-lensing. We thus can now present the largest sample of optical/CCD nova lightcurves towards M 31 to date. We also obtained thorough coverage of the light curve before and after the eruption thanks to the long-term monitoring. We apply a nova taxonomy to our nova candidates and found 29 S-class novae, 10 C-class novae, 2 O-class novae, and 1 J-class nova. We investigated a universal decline law on the S-class novae. In addition, we correlated our catalogue with the literature and found 4 potential recurrent novae. Part of our catalogue has been used to search for optical counterparts of the super soft X-ray sources detected in M 31. Optical surveys like WeCAPP, when coordinated with multi-wavelength observation, will continue to shed light on the underlying physical mechanism of novae in the future.

Variation of Indoor Radon Levels in Some Caves of Parque Estadual Turistico do Alto Ribeira (PETAR), SP, Brazil with Ventilation and Rain  

SciTech Connect

In order to assess the radon exposure for the tour guide workers, radon levels in several galleries of the most visited caves of PETAR (High Ribeira River Turistic State Park), were determined by using Makrofol E tracks detectors. A two-years surveillance, from 2003 to 2005, showed radon average levels varying from 153{+-}44 Bq{center_dot}m{sup -3} to 6358{+-}1619 Bq{center_dot}m{sup -3}. Those results showed that the wide variation between the minimum and maximum concentrations values are strongly related with cave ventilation. In order to establish other factors contributing to this variation, beside the well known temperature effect, rain data over the entire period were also considered, showing that, apparently, radon concentrations inside the caves rise with drought.

Genetic Characterization of Goutanap Virus, a Novel Virus Related to Negeviruses, Cileviruses and Higreviruses  

PubMed Central

Pools of mosquitoes collected in Côte d’Ivoire and Mexico were tested for cytopathic effects on the mosquito cell line C6/36. Seven pools induced strong cytopathic effects after one to five days post infection and were further investigated by deep sequencing. The genomes of six virus isolates from Côte d’Ivoire showed pairwise nucleotide identities of ~99% among each other and of 56%–60% to Dezidougou virus and Wallerfield virus, two insect-specific viruses belonging to the proposed new taxon Negevirus. The novel virus was tentatively named Goutanap virus. The isolate derived from the Mexican mosquitoes showed 95% pairwise identity to Piura virus and was suggested to be a strain of Piura virus, named C6.7-MX-2008. Phylogenetic inferences based on a concatenated alignment of the methyltransferase, helicase, and RNA-dependent RNA polymerase domains showed that the new taxon Negevirus formed two monophyletic clades, named Nelorpivirus and Sandewavirus after the viruses grouping in these clades. Branch lengths separating these clades were equivalent to those of the related genera Cilevirus, Higrevirus and Blunervirus, as well as to those within the family Virgaviridae. Genetic distances and phylogenetic analyses suggest that Nelorpivirus and Sandewavirus might form taxonomic groups on genus level that may define alone or together with Cilevirus, Higrevirus and Blunervirus a viral family.

Notes on human cases of cystic echinococcosis in Peru.  

PubMed

Cystic echinococcosis (CE) is a high prevalent zoonosis in the central and southern Peruvian Andes. Serum samples (n50)from patients presenting presumptive clinical and radiological diagnosis of CE (group 1), were tested for antibodies against Echinococcus granulosus metacestode using Arc-5 double diffusion assay (DD5), immunoelectrophoresis (IEF), and immunoelectrotransfer blot (EITB) techniques. Serum samples (n18) from patients presenting other parasite infections (paragonomiasis, cysticercosis, and fascioliasis) or healthy blood donors (n15), were designated as control groups. The overall sensitivity of the tests was of 94% (DD5 and IEF tests) or 96% (EITB test). Only patients from group 1 were seropositive for CE. Polypeptides of 21, 31, and 48 kDa were considered positive for CE. Based on these results, this study demonstrates that CE also occurs in other coastal departments (Piura, Ancash, Ica, Arequipa, and Tacna) besides Lima. PMID:16862333

Based on their genome organization and phylogenetic relationship, the six viruses, designated Negev, Ngewotan, Piura, Loreto, Dezidougou, and Santana, appear to form a new taxon, tentatively designated Negevirus. Their closest but still distant relatives are citrus leposis virus C (CiLV-C) and viruses in the genus Cilevirus, which are mite-transmitted plant viruses. The negeviruses replicate rapidly and to high titer (up to 1010 PFU/ml) in mosquito cells, producing extensive cytopathic effect and plaques, but they do not appear to replicate in mammalian cells or mice. A discussion follows on their possible biological significance and effect on mosquito vector competence for arboviruses. PMID:23255793

Southern Oscillation Signal in South American Palaeoclimatic Data of the Last 7000 Years  

NASA Astrophysics Data System (ADS)

During strong El Niño events, rainfall anomalies and changes in wind patterns are observed in different regions of South America. Along the central Brazilian coast, during the 1983 El Niño year, the frontal systems were blocked to the south, provoking a reversal of the longshore sand transport. Long-duration reversals of longshore transport were also recorded in Holocene beach-ridge terraces from the Rio Doce coastal plain. This led to the formulation of a model relating these reversals of longshore transport to El Niño-like conditions. El Niño-like conditions are past average climate situations that generate the same perturbations as the strong El Niño events observed during the last decade. They are likely to correspond to the long-duration low phase of the Southern Oscillation. To confirm this hypothesis we compared the Holocene beach-ridge record with other palaeoenvironmental records from regions where strong El Niño events would have a substancial signal as well: (1) water-level fluctuations of Lake Titicaca, (2) a pollen and sediment record in an eastern Amazonian lake, (3) changes of the Rio Xingu discharge in eastern Amazonia, and (4) variations of sand supply at the Rio Piura and Rio Chira outlets in the Sechura Desert. The occurrences of El Niño-like conditions were numerous before 3900-3600 yr B.P., absent between 39003600 and 2800-2500 yr B.P., and infrequent after 2800-2500 yr B.P.

Traditional medicinal plant use in Northern Peru: tracking two thousand years of healing culture  

PubMed Central

This paper examines the traditional use of medicinal plants in Northern Peru, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin. Northern Peru represents the center of the old Central Andean "Health Axis," stretching from Ecuador to Bolivia. The roots of traditional healing practices in this region go at least as far back as the Moche period (AC 100–800). Although about 50% of the plants in use reported in the colonial period have disappeared from the popular pharmacopoeia, the plant knowledge of the population is much more extensive than in other parts of the Andean region. 510 plant species used for medicinal purposes were collected, identified and their vernacular names, traditional uses and applications recorded. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had twelve species, and Apiaceae and Poaceae 11 species. The highest number of species was used for the treatment of "magical/ritual" ailments (207 species), followed by respiratory disorders (95), problems of the urinary tract (85), infections of female organs (66), liver ailments (61), inflammations (59), stomach problems (51) and rheumatism (45). Most of the plants used (83%) were native to Peru. Fresh plants, often collected wild, were used in two thirds of all cases, and the most common applications included the ingestion of herb decoctions or the application of plant material as poultices.

Plasmodium vivax hospitalizations in a monoendemic malaria region: severe vivax malaria?  

PubMed

Severe malaria caused by Plasmodium vivax is no longer considered rare. To describe its clinical features, we performed a retrospective case control study in the subregion of Luciano Castillo Colonna, Piura, Peru, an area with nearly exclusive vivax malaria transmission. Severe cases and the subset of critically ill cases were compared with a random set of uncomplicated malaria cases (1:4). Between 2008 and 2009, 6,502 malaria cases were reported, including 106 hospitalized cases, 81 of which fit the World Health Organization definition for severe malaria. Of these 81 individuals, 28 individuals were critically ill (0.4%, 95% confidence interval = 0.2-0.6%) with severe anemia (57%), shock (25%), lung injury (21%), acute renal failure (14%), or cerebral malaria (11%). Two potentially malaria-related deaths occurred. Compared with uncomplicated cases, individuals critically ill were older (38 versus 26 years old, P < 0.001), but similar in other regards. Severe vivax malaria monoinfection with critical illness is more common than previously thought. PMID:24752683

Ages of Quaternary Rio Grande terrace-fill deposits, Albuquerque area, New Mexico  

USGS Publications Warehouse

Results from luminescence dating on 13 samples from the Albuquerque area show that major-drainage fluvial deposits represent significant periods of aggradation that formed paired, correlatable terraces on the east and west margins of the Rio Grande valley . The youngest terrace fills (Primero Alto) formed during late Pleistocene as a result of streamflow variations with climate cooling during Marine Oxygen-Isotope Stage 3; our ages suggest aggradation of the upper part of the fill occurred at about 47–40 ka . Deposits of the second (Segundo Alto) terraces reached maximum height during climate cooling in the early part of Marine Oxygen-Isotope Stage 5 as late as 90–98 ka (based on dated basalt flows) . Our luminescence ages show considerable scatter and tend to be younger (range from 63 ka to 162 ka) . The third (Tercero Alto) and fourth (Cuarto Alto) terraces are dated on the basis of included volcanic tephra. Tercero Alto terrace-fill deposits contain the Lava Creek B tephra (639 ka), and Cuarto Alto terrace-fill deposits contain tephra of the younger Bandelier Tuff eruption (1 .22 Ma), the Cerro Toledo Rhyolite (1 .47 Ma), and the older Bandelier Tuff eruption (1 .61 Ma). These periods of aggradation culminated in fluvial terraces that are preserved at maximum heights of 360 ft (Cuarto Alto), 300 ft. (Tercero Alto), 140 ft (Segundo Alto), and 60 ft. (Primero Alto) above the modern floodplain. Despite lithologic differences related to local source-area contributions, these terracefill deposits can be correlated across the Rio Grande and up- and down-valley for tens of miles based on maximum height of the terrace above the modern floodplain.

Mitochondrial D-loop nucleotide diversity in Astyanax (Osteichthyes, Characidae) from the upper Paraná and upper Paraguay River basins.  

PubMed

The morphological discrimination between the species Astyanax altiparanae and A. asuncionensis of the upper Paraná River and Paraguay River basins, respectively, has always been difficult. Two D-loop haplogroups of A. altiparanae are known, one with the presence (AltoPR) or the absence (AltoPR-D) of a 32-bp block similar to that in A. asuncionensis. We examined these samples to characterize A. altiparanae and verify whether A. asuncionensis occurred in the upper Paraná River prior to the submergence of the Sete Quedas Falls when Itaipu reservoir was impounded. D-loop sequences were analyzed in A. altiparanae of the upper Paraná and Iguaçu Rivers and those of A. asuncionensis of the upper Paraguay River. The haplogroup AltoPR was found at all sites of the upper Paraná and Iguaçu Rivers, whereas AltoPR-D occurred in the Itaipu reservoir, floodplain and in the Tietê and Grande Rivers. Two haplogroups of A. asuncionensis were identified and both did not have the 32-bp block. However, AltoPR and AltoPR-D differed from one another in 5.1% of their bases and between 8.9 and 12.5% with regard to the haplogroups of the upper Paraguay basin. Further, AltoPR-D occurred in the Grande River upstream the Marimbondo Falls and other older reservoirs than Itaipu. The results reject the hypothesis of the establishment of A. asuncionensis and suggest that the haplogroup AltoPR-D existed in the upper Paraná River before the impounding of the Itaipu reservoir. Moreover, morphological similarity and high genetic variation within the altiparanae/asuncionensis group suggest the existence of a cryptic species complex. PMID:22614275

Molecular study of Astyanax altiparanae (Osteichthyes, Characidae) as a probable species complex.  

PubMed

Astyanax altiparanae, belonging to the bimaculatus group, which includes species with similar colors and morphology, occurs in the upper Paraná River basin. As the use of mitochondrial DNA has made great strides in the diagnosis of species, in previous researches, two strains were detected in A. altiparanae with a high divergence in the D-loop region, provisionally called AltoPR and AltoPR-D. Evidence led to the hypothesis that the two strains did not belong to the same species. Phylogenetic hypotheses were produced by maximum-likelihood. Mean internal distances of the AltoPR and AltoPR-D groups were respectively 0.002 and 0.003, with the distance between them being 0.037. Sequences from GenBank of specimens collected from the Paraíba do Sul River basin were also divided into two groups, of which one may be identified as AltoPR. Since the other group provided an intermediate distance when compared to AltoPR-D, an in-depth investigation was required. The other species analyzed showed a greater distance and was revealed to be a monophyletic taxon. The results suggested that they are really two species and that neither corresponds to the other species used in the current study. PMID:25117359

Robust decision-making under uncertainty for a moorland ecosystem's water resources management under scenarios of climate variability  

NASA Astrophysics Data System (ADS)

A climate-informed water resources decision-making framework can help effectively manage the complexity of water resources while adapting to climate change effects. The decision-making framework allows for more effective and inclusive water resources management, and results in better informed decisions about water allocation and adaptation strategies. This study focuses on modeling the moorland ecosystem's water resources management under climate variability, and strengthening the capacities of local actors through a robust decision-making under uncertainty framework to analyze and plan water resources use in the region of Piura, Peru. The objective is to determine the reliability of the moorland ecosystem's water supply and to provide relevant hydrological information under scenarios of climate variability and other non-climate uncertainties. As a first step, a participatory workshop was carried out with key regional actors to obtain information that would help to define the uncertainties that define availability of water resources, the potential strategies for adaptation to improve existing conditions, and the performance indicators by which to assess these uncertainties and strategies. For the identification of these factors, we used the XLRM assessment framework (eXogenous uncertainties, policy Levers, Relationships, and Measures). The XLRM framework allows us to organize the important elements of risk analysis and vulnerability in the four assessment categories. This study also used the WEAP (Water Evaluation And Planning system) platform to support water resources planning and decision-making under uncertainty e.g. climate change and other stresses in the system. Within the R component, WEAP was used to model the hydrological response of the moorland ecosystem. The model includes the results of the XLRM framework and seeks to determine the importance that the moorlands have on the regional water system. Results of this model include the head flows produced that feed the watershed management model under different sensitivity scenarios of precipitation and temperature. Vulnerability is observed on the produced base flows of the moorlands ecosystem due to a decrease in moorlands' area and to climate variability-related impacts during the 50 years of simulation. This system-level vulnerability has significant effects on the water supply available for downstream demand sites, including rural and agricultural users that rely exclusively on a reservoir.

Shadows of the colonial past - diverging plant use in Northern Peru and Southern Ecuador  

PubMed Central

This paper examines the traditional use of medicinal plants in Northern Peru and Southern Ecuador, with special focus on the Departments of Piura, Lambayeque, La Libertad, Cajamarca, and San Martin, and in Loja province, with special focus on the development since the early colonial period. Northern Peru represents the locus of the old Central Andean "Health Axis." The roots of traditional healing practices in this region go as far back as the Cupisnique culture early in the first millennium BC. Northern Peru and Southern Ecuador share the same cultural context and flora but show striking differences in plant use and traditional knowledge. Two hundred fifteen plant species used for medicinal purposes in Ecuador and 510 plant species used for medicinal purposes in Peru were collected, identified,. and their vernacular names, traditional uses, and applications recorded. This number of species indicates that the healers, market vendors, and members of the public interviewed in Peru still have a very high knowledge of plants in their surroundings, which can be seen as a reflection of the knowledge of the population in general. In Ecuador much of the original plant knowledge has already been lost. In Peru, 433 (85%) were Dicotyledons, 46 (9%) Monocotyledons, 21 (4%) Pteridophytes, and 5 (1%) Gymnosperms. Three species of Giartina (Algae) and one species of the Lichen genus Siphula were used. The families best represented were Asteraceae with 69 species, Fabaceae (35), Lamiaceae (25), and Solanaceae (21). Euphorbiaceae had 12 species, and Poaceae and Apiaceae each accounted for 11 species. In Ecuador the families best represented were Asteraceae (32 species), Euphorbiaceae, Lamiaceae, and Solanaceae (11 species each), and Apiaceae, Fabaceae, Lycopodiaceae (9 species each). One hundred eighty-two (85%) of the species used were Dicotyledons, 20 Monocotyledons (9.3%), 12 ferns (5.5%), and one unidentified lichen was used. Most of the plants used (83%) were native to Peru and Ecuador. Fresh plants, often collected wild, were used in two thirds of all cases in Peru, but in almost 95% of the cases in Ecuador. The most common applications included the ingestion of herb decoctions or the application of plant material as poultices. Although about 50% of the plants in use in the colonial period have disappeared from the popular pharmacopoeia, the overall number of plant species used medicinally has increased in Northern Peru, while Southern Ecuador shows a decline of plant knowledge since colonial times.

Identification of an overprinting gene in Merkel cell polyomavirus provides evolutionary insight into the birth of viral genes  

PubMed Central

Many viruses use overprinting (alternate reading frame utilization) as a means to increase protein diversity in genomes severely constrained by size. However, the evolutionary steps that facilitate the de novo generation of a novel protein within an ancestral ORF have remained poorly characterized. Here, we describe the identification of an overprinting gene, expressed from an Alternate frame of the Large T Open reading frame (ALTO) in the early region of Merkel cell polyomavirus (MCPyV), the causative agent of most Merkel cell carcinomas. ALTO is expressed during, but not required for, replication of the MCPyV genome. Phylogenetic analysis reveals that ALTO is evolutionarily related to the middle T antigen of murine polyomavirus despite almost no sequence similarity. ALTO/MT arose de novo by overprinting of the second exon of T antigen in the common ancestor of a large clade of mammalian polyomaviruses. Taking advantage of the low evolutionary divergence and diverse sampling of polyomaviruses, we propose evolutionary transitions that likely gave birth to this protein. We suggest that two highly constrained regions of the large T antigen ORF provided a start codon and C-terminal hydrophobic motif necessary for cellular localization of ALTO. These two key features, together with stochastic erasure of intervening stop codons, resulted in a unique protein-coding capacity that has been preserved ever since its birth. Our study not only reveals a previously undefined protein encoded by several polyomaviruses including MCPyV, but also provides insight into de novo protein evolution. PMID:23847207

PYRAMIR: construction and implementation of the world's first infrared pyramid sensor  

NASA Astrophysics Data System (ADS)

In this paper we present an overview of the construction and implementation of the unmodulated infrared pyramid wavefront sensor PYRAMIR at the Calar Alto 3.5 m telescope. PYRAMIR is an extension of the existing visible Shack-Hartmann adaptive optics system ALFA, which allows wavefront sensing in the near-infrared wavefront regime. We describe the optical setup and the calibration procedure of the pyramid wavefront sensor. We discuss possible drawbacks of the calibration and show the results gained on Calar Alto.

Fast and accurate read alignment for resequencing  

PubMed Central

Motivation: Next-generation sequence analysis has become an important task both in laboratory and clinical settings. A key stage in the majority sequence analysis workflows, such as resequencing, is the alignment of genomic reads to a reference genome. The accurate alignment of reads with large indels is a computationally challenging task for researchers. Results: We introduce SeqAlto as a new algorithm for read alignment. For reads longer than or equal to 100 bp, SeqAlto is up to 10 × faster than existing algorithms, while retaining high accuracy and the ability to align reads with large (up to 50 bp) indels. This improvement in efficiency is particularly important in the analysis of future sequencing data where the number of reads approaches many billions. Furthermore, SeqAlto uses less than 8 GB of memory to align against the human genome. SeqAlto is benchmarked against several existing tools with both real and simulated data. Availability: Linux and Mac OS X binaries free for academic use are available at http://www.stanford.edu/group/wonglab/seqalto Contact: whwong@stanford.edu PMID:22811546

Enrichment and Association of Bacteria and Particulates in Salt Marsh Surface Water  

PubMed Central

Elevated counts of bacteria were found during outgoing tides in surface microlayers (?300 ?m) of Sippewissett salt marsh, Falmouth, Massachusetts, and Palo Alto salt marsh, Palo Alto, California. At both sampling sites, the degrees by which bacteria were concentrated into the surface microlayer were linearly dependent upon surface concentration of particulate material. A significant percentage of bacteria in the microlayer were found to be attached to particulate material, while bacterial populations in the subsurface water were largely planktonic. Proportions of the bacterial populations which could be grown on seawater nutrient agar were also greater in the microlayer than in the subsurface waters and were positively correlated with the fraction of bacteria attached to particulate matter. Data from these studies suggest that particulates in the microlayer waters of the salt marsh influenced the observed increase in both the readily grown and the total numbers of bacteria.

Groundwater arsenic in Chimaltenango, Guatemala.  

PubMed

In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking water, and sent to the USA for analysis. The only site found to have a concentration above the 10 ?g/L World Health Organization provisional guideline for arsenic in drinking water was Cerro Alto, where the average concentration was 47.5 ?g/L. A health risk assessment based on the arsenic levels found in Cerro Alto showed an increase in noncarcinogenic and carcinogenic risks for residents as a result of consuming groundwater as their primary drinking water source. Using data from the US Geological Survey and our global positioning system data of the sample locations, we found Cerro Alto to be the only site sampled within the tertiary volcanic rock layer, a known source of naturally occurring arsenic. Recommendations were made to reduce the levels of arsenic found in the community's drinking water so that the health risks can be managed. PMID:25252357

Early Experiences with Personal Health Records  

PubMed Central

Over the past year, several payers, employers, and commercial vendors have announced personal health record projects. Few of these are widely deployed and few are fully integrated into ambulatory or hospital-based electronic record systems. The earliest adopters of personal health records have many lessons learned that can inform these new initiatives. We present three case studies—MyChart at Palo Alto Medical Foundation, PatientSite at Beth Israel Deaconess Medical Center, and Indivo at Children’s Hospital Boston. We describe our implementation challenges from 1999 to 2007 and postulate the evolving challenges we will face over the next five years. PMID:17947615

Ground state energy of large atoms in a self-generated magnetic field  

E-print Network

We consider a large atom with nuclear charge $Z$ described by non-relativistic quantum mechanics with classical or quantized electromagnetic field. We prove that the absolute ground state energy, allowing for minimizing over all possible self-generated electromagnetic fields, is given by the non-magnetic Thomas-Fermi theory to leading order in the simultaneous $Z\\to \\infty$, $\\al\\to 0$ limit if $Z\\al^2\\leq \\kappa$ for some universal $\\kappa$, where $\\al$ is the fine structure constant.

The Black Mountain asperity - Seismic hazard of the southern San Francisco Peninsula, California  

NASA Technical Reports Server (NTRS)

A slip deficit region running 75 km from Black Mountain south of Palo Alto to San Juan Battista is studied to assess earthquake hazard. If this region were ruptured in its entirety, the event would produce a M-sub-s = 6.9 earthquake. The conditional probability of this rupturing in the near future is the highest of any section of the San Andreas fault except Parkfield. This earthquake would rupture 30 km farther northwest and be about 3 times larger than that previously proposed by others (Lindh, 1983, and Sykes and Nishenko, 1984). This constitutes a greater risk to the southern San Francisco Peninsula than previously expected.

Video-coaching as biofeedback tool to improve gated treatments: Possibilities and limitations.  

PubMed

For respiratory gated radiotherapy the manufacturers of linear accelerators offer dedicated gating technologies. The video-based Varian RPM Gating system (Varian Medical Systems, Palo Alto/CA, USA) includes in a standard configuration a support tool for regular breathing called audiocoaching. As this approach has limitations regarding direct control of the patient's breathing due to a missing feedback, we designed an additional tool offering videocoaching. In order to evaluate the impact of this additional functionality, we measured parameters defining the image quality of 4D-CT data as well as the treatment duration which is mainly influenced by the patient's limited ability to achieve a stable breathing pattern.

NASA Astrophysics Data System (ADS)

Several alto saxophone players' vibratos have been recorded. The signals are analyzed using time-frequency methods in order to estimate the frequency modulation (vibrato rate) and the amplitude modulation (vibrato extent) of each vibrato sample. Some parameters are derived from the results in order to separate the two ways of vibrato playing: vibrato ``à la machoire'' and vibrato ``sur l'air.'' Moreover, time domain simulations of single-reed instrument vibratos are created. The model is controlled by two parameters: the mouth overpressure and a parameter characterizing the reed-mouthpiece system. Preliminary comments and comparisons between the simulated vibratos and recorded vibratos results are made.

RESISTANCE AND CROSS RESISTANCE OF ESCHERICHIA COLI S MUTANTS TO THE RADIOMIMETIC AGENT NITROFURAZONE  

PubMed Central

Woody-Karrer, Pearl (Palo Alto Medical Research Foundation, Palo Alto, Calif.) and Joseph Greenberg. Resistance and cross resistance of Escherichia coli S mutants to the radiomimetic agent nitrofurazone. J. Bacteriol. 85:1208–1216. 1963.—Cross-resistance relationships are described for 73 mutants of Escherichia coli strain S selected in one step for resistance to nitrofurazone. The test agents included ultraviolet radiation, five radiomimetic compounds, and penicillin; 12 different types of mutants could be selected. Two of these were chemoresistant, three were identical to radioresistant types previously isolated by use of other radiomimetic agents, and seven represented previously unobserved radioresistant types. The majority of radioresistant strains did not respond to plating-medium reactivation after ultraviolet radiation, despite the ultraviolet radiation responses of several minority representative strains. The data presented indicate that radioresistance in E. coli S does not involve resistance to most toxic agents; on the other hand, cross resistance to radiomimetic compounds is not restricted to alkylating agents.

Recent GRBs observed with the 1.23m CAHA telescope and the status of its upgrade

We report on optical observations of Gamma-Ray Bursts (GRBs) followed up by our collaboration with the 1.23m telescope located at the Calar Alto observatory. The 1.23m telescope is an old facility, currently undergoing upgrades to enable fully autonomous response to GRB alerts. We discuss the current status of the control system upgrade of the 1.23m telescope. The upgrade is being done by the ARAE our group, based on members of IAA (Instituto de Astrofiisica de Andalucia). Currently the ARAE group is responsible to develop the BOOTES network of robotic telescopes based on the Remote Telescope System, 2nd Version (RTS2), which controls the available instruments and interacts with the EPICS database of Calar Alto. Currently the telescope can run fully autonomously or under observer supervision using RTS2.

Vielfarben-Klassifikation in CADIS und die Suche nach Quasaren.  

NASA Astrophysics Data System (ADS)

The Calar Alto Deep Imaging Survey (CADIS) is a deep photometric multicolor survey on ten rather empty fields of the sky well suited for extragalactic studies. As part of this work, a photometric classification technique was developed which sorts all objects into the classes "star", "galaxy", "quasar" and "unclassified". This classification is based on published spectral libraries. It also performs a redshift estimation for galaxies and quasars. Instead of a template fitting procedure, a mathematically almost equivalent procedure is used in this work that is essentially deduced from classification theory and can be implemented much more efficiently than a template fitting algorithm. A general introduction into the subject of classification is given in this report and its application to CADIS is detailed. The performance of the classification was checked by taking slit spectra of about 100 objects in the CADIS 9 h- and 16 h-fields using MOSCA at Calar Alto. Another 150 identifications in the 3 h-field were taken from the Canada-France Redshift Survey, increasing the number of objects with both photometric and spectroscopic classification to about 250. Among these, only five objects were misclassified (=2%) showing the classification to be excellent. After sorting the CADIS objects into the various classes, the sample of quasar candidates was analysed in more detail.

This work was conducted to determine the occurrence of Trichogramma wasp species in Lara State, Venezuela. Lepidopteran egg samples collected from various crop leaves were observed daily under laboratory conditions for emergence of Trichogramma species adult wasps. Trichogramma were also obtained from traps containing eggs from the hosts Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). In the laboratory, specimens of Trichogramma species were mounted on microscope slides to show male genitalia and other morphological characters used for its identification. Trichogramma atopovirilia Oatman y Platner emerged from S. frugiperda eggs collected in a cornfield at La Palomera, Humocaro Alto and at El Parchal, Humocaro Bajo, Municipio Morán. T. atopovirilia also emerged from S. frugiperda eggs collected in a cornfield at Sabana Grande and from S. cerealella eggs used as traps in a pepper culture at Tintinal, Municipio Andrés Eloy Blanco. T. exiguum Pinto y Platner emerged from S. frugiperda eggs used as traps or collected in cornfield at Totumito and at La Palomera, Humocaro Alto. T. pretiosum Riley emerged from Phthorimaea operculella Zeller eggs collected on stored potatoes at Monte Carmelo, Sanare. The identification of Trichogramma species in Lara State would be useful in the development of biological control programs for lepidopteran pests. PMID:17934619

Springtime cloud properties in the Taiwan Strait: synoptic controls and local processes  

NASA Astrophysics Data System (ADS)

This paper examines the springtime cloud properties in the Taiwan Strait (TS), with emphases on their dependence on synoptic controls and local processes, using a suite of in situ and remote sensing observations. Cloud properties in the TS are inferred from a combination of MODIS and in situ observations and further classified into two synoptic conditions: continental cold air surge and frontal system. The study reveals a predominance of synoptic-scale controls in regulating the cloud properties in the TS. The sensitivity of clouds to the local thermodynamic mechanisms as well as the underlying surface conditions is fundamentally dependent on synoptic-scale flow patterns. The springtime clouds over the TS are commonly a mixture of stratocumulus and alto clouds. More precisely, there is a preponderance of stratocumulus over the strait. A preferential occupancy of stratiform alto clouds is recognized during cold air surge, whereas vertical development of cloud layers (mostly the stratocumulus) is commonly observed with frontal passage. The most distinct difference between the local clouds formation associated with the two synoptic conditions is the suppression of very low cloud and fog along with cold air surge. Stratus clouds and fog are present within the northward prefrontal airflow from warmer to colder water sites, along with an increase in stability relating to lower altitudes of boundary layer clouds. Although the rainfall occurrences are about the same for both synoptic conditions, the frontal rain amounts are larger on average.

HS 0705+6700: a New Eclipsing sdB Binary  

NASA Astrophysics Data System (ADS)

HS 0705+6700 is a newly discovered eclipsing sdB binary system consisting of an sdB primary and a cool secondary main sequence star. CCD photometry obtained in October and November 2000 with the 2.5m Nordic (NOT) telescope (La Palma, Tenerife) in the B passband and with the 2.2m Calar Alto telescope (CAFOS, R filter) yielded eclipse light curves with complete orbital phase coverage at high time resolution. A periodogram analysis of 12 primary minimum times distributed over the time span from October 2000 to March 2001 allowed to derive the following exact period and linear ephemeris: prim. min. = HJD 2451822.759782(22) + 0.09564665(39) ? E A total of 15 spectra taken with the 3.5m Calar Alto telescope (TWIN spectrograph) on March 11-12, 2001, were used to establish the radial velocity curve of the primary star (K1 = 85.8 km/s) , and to determine its basic atmospheric parameters (Teff = 29300 K, log g = 5.47). The B and R light curves were solved using our Wilson-Devinney based light curve analysis code MORO (Drechsel et al. 1995, A&A 294, 723). The best fit solution yielded exact system parameters consistent with the spectroscopic results. Detailed results will be published elsewhere (Drechsel et al. 2001, A&A, in preparation).

Oncology Practice Trends From the National Practice Benchmark, 2005 through 2010  

PubMed Central

Oncology Metrics, a division of Altos Solutions, has been conducting organized surveys of practicing oncologists since 2005. In this article, we present data that represent trends in community oncology practice over a 6-year period, 2005 to 2010, and make projections on the basis of these data. Over the next 3 years, operating margins will continue to decrease, gains in business and clinical operating efficiencies will slow, and labor costs will rise. The cost of drugs provided to patients is also increasing while the amount above cost that is being reimbursed continues a slow decline. The gap between practice costs and practice revenue will continue to narrow, and as this occurs, community oncology practices will find it difficult to maintain their current business models.

Combining these observations with those obtained similarly using the Calar Alto telescopes (Paper I, ) we find a strong positive correlation between the near-infrared concentration index and the galaxy H-band luminosity, and we analyze the consequent dependence of near-infrared growth-curves on H-band luminosity. For a description of the H band photometric system, see e.g. (2 data files).

Parque Estadual Turistico do Alto Ribeira (PETAR) is located in the South-western part of Sao Paulo State, in the Ribeira Valley. In this national state park a large number of caves are found, which are among the most visited of the country. These caves, located in a karstic zone, are characterized by the presence of carbonaceous rocks frequently fractured and collapsed. Although, carbonates (dolomites and calcitic rocks) usually have low U content, this element can be found in the structure of the surrounding rocks. This paper aims to determine {sup 238}U, {sup 234}U, {sup 226}Ra and {sup 210}Pb concentration in samples of rock, soil, river water and sediment, in Santana cave. The radionuclide {sup 238}U was determined by alpha spectrometry using a surface barrier detector. {sup 226}Ra and {sup 210}Pb were determined by measuring the gross alpha and beta activity on a gas flow proportional counter.

MRI Artifacts of a Metallic Stent Derived From a Human Aorta Specimen  

SciTech Connect

Magnetic resonance imaging has proved to be a useful technique to get images of the whole body. However, the presence of ferromagnetic material can cause susceptibility artifacts, which result from microscopic gradients that occur near the boundaries between areas displaying different magnetic susceptibility. These gradients cause dephasing of spins and frequency shifts in the surrounding tissues. Intravoxel dephasing and spatial mis-registration can degrade image quality. An aorta with a metallic stent was preserved in formaldehyde at 10% inside acrylic cylinders and used to obtain MR images. We tested pulsed spin echo and gradient echo sequences to improve image quality. All experiments were performed on a 7T/21 cm Varian system (Varian, Inc, Palo Alto, CA) equipped with Direct Drive technology and a 16-rung birdcage coil transceiver. The presence of metallic stents produces a lack of signal that might give falsely reassuring appearances within the vessel lumen.

Optical design and cryogenic mounting of the optics for a pyramid waterfront sensor working in the near infrared wavelength range  

NASA Astrophysics Data System (ADS)

This paper describes the whole process of designing, manufacturing and assembling the optics for an infrared pyramid wavefront sensor, called PYRAMIR. This sensor is built to work with the adaptive optical system at the 3.5 m telescope of the Calar Alto Observatory, Spain, which controls a 97 actuator deformable mirror. PYRAMIR is working in combination with an infrared science camera, which is used for observations. Since the wavefront sensor works in the near infrared (1.0 ?m to 2.4 ?m), the detector, the optics and all the mechanics are cooled to liquid nitrogen temperature. For this cryogenic condition, special care has to be taken for the optical design and the mounting of the lenses. We describe in detail the process from infrared optical design and cryo-mechanical engineering, to the final assembly of the opto-mechanical units and testing in the lab. Technical solutions are illustrated and the final performance is demonstrated.

Opto-mechanical design of PANIC  

NASA Astrophysics Data System (ADS)

PANIC, the Panoramic Near-Infrared Camera, is a new instrument for the Calar Alto Observatory. A 4x4 k detector yields a field of view of 0.5x0.5 degrees at a pixel scale of 0.45 arc sec/pixel at the 2.2m telescope. PANIC can be used also at the 3.5m telescope with half the pixel scale. The optics consists of 9 lenses and 3 folding mirrors. Mechanical tolerances are as small as 50 microns for some elements. PANIC will have a low thermal background due to cold stops. Read-out is done with MPIA's own new electronics which allows read-out of 132 channels in parallel. Weight and size limits lead to interesting design features. Here we describe the opto-mechanical design.

The area is located between the cities of Campo Magro and Campo Largo, Paraná plateau in the first part of theAlto Iguaçu basin. This study aims to raise the concepts relating to environmental geomorphology, to identify the anthropogenic impacts caused in the reservoir areas, identify the environmental compartments found around the dam and characterize the geologic and physiographic region. It was found that the area has intense anthropogenic influence, as urban growth is present in areas and wavy and rough terrain, subject to mass movements and floods. Besides these aspects, the use of land for agriculture contributes to fragility of the area. PMID:23424831

Currently there are three blast furnaces in operation and one more about to finish its general repair. This last one is to remain as a back-up unit. Because of blast furnace hearth wear outs AHMSA has developed some maintenance procedures. These procedures are based on titanium ore additions and hearth thermic control monitoring. There are also some other maintenance practices adopted to the working operations to assure that such operations detect and avoid in time hearth wear outs that place personnel and/or the unit in danger (due to hearth leaks). This paper describes titanium ore addition to No. 2 blast furnace during the final campaign and it also illustrates maintenance practices and continuous monitoring of temperature trends both of which were implemented at AHMSA`s No. 5 blast furnace.

VizieR Online Data Catalog: Kepler planet host candidates imaging (Lillo-Box+, 2014)  

NASA Astrophysics Data System (ADS)

We applied the lucky imaging technique to the selected targets to achieve diffraction-limited resolution. We used the AstraLux North instrument located at the 2.2m telescope at the Calar Alto Observatory (Almeria, Spain). The targets were observed along three visibility windows of the Kepler field during 2011, 2012, and 2013. The results regarding the non-isolated KOIs of observations on 2011 were published in Lillo-Box et al. (2012A&A...546A..10L, Cat. J/A+A/546/A10). In the present work, we report the results concerning the isolated candidates observed in 2011 and the new results for the 2012-2013 observing runs. (5 data files).

Stratigraphical distribution of the Ordovician conodont Erraticodon Dzik in Argentina  

NASA Astrophysics Data System (ADS)

Three different species of the Ordovician genus Erraticodon Dzik are described and illustrated. Erraticodon patu Cooper is reported from the Lower-Midde Ordovician strata of the Acoite and Alto del Cóndor formations. E. cf. Erraticodon balticus and Erraticodon hexianensis from Middle Ordovician carbonate deposits of the San Juan Formation are analyzed and compared to specimens of these species from Australia, China, Newfoundland, and Baltica. E. patu and E. hexianensis are recorded for first time in the San Juan Formation of Precordillera. The elements of E. cf. E. balticus resemble closely E. balticus Dzik but lack the important denticle on the posterior process of the S elements. An evaluation of the stratigraphic occurrences of these species relative to those of key Lower and Middle Ordovician conodont species such as Trapezognathus diprion Lindström, Oepikodus intermedius Serpagli, Baltoniodus triangularis (Lindström), Baltoniodus navis Lindström, Yangtzeplacognathus crassus (Chen and Zhang) and Eoplacognathus pseudoplanus (Viira) indicates they value for biostratigraphic correlation.

Verification of FANTASTIC integrated code  

NASA Technical Reports Server (NTRS)

FANTASTIC is an acronym for Failure Analysis Nonlinear Thermal and Structural Integrated Code. This program was developed by Failure Analysis Associates, Palo Alto, Calif., for MSFC to improve the accuracy of solid rocket motor nozzle analysis. FANTASTIC has three modules: FACT - thermochemical analysis; FAHT - heat transfer analysis; and FAST - structural analysis. All modules have keywords for data input. Work is in progress for the verification of the FAHT module, which is done by using data for various problems with known solutions as inputs to the FAHT module. The information obtained is used to identify problem areas of the code and passed on to the developer for debugging purposes. Failure Analysis Associates have revised the first version of the FANTASTIC code and a new improved version has been released to the Thermal Systems Branch.

Diffraction Limited Imaging of High Redshift Galaxies with Adaptive Optics  

E-print Network

The major cornerstone of future ground-based astronomy is imaging and spectroscopy at the diffraction limit using adaptive optics. To exploit the potential of current AO systems, we have begun a survey around bright stars to study intermediate redshift galaxies at high resolution. Using ALFA to reach the diffraction limit of the 3.5-m telescope at Calar Alto allows us to study the structure of distant galaxies in the near-infrared at scales of 100-150 pc for z=0.05 and at scales 1.0-1.5 kpc at z=1. In this contribution we present the initial results of this project, which hint at the exciting prospects possible with the resolution and sensitivity available using an AO camera on the 8-m class VLT.

Virtual tools for teaching electrocardiographic rhythm analysis.  

PubMed

Electrocardiographic (ECG) rhythm analysis is inadequately taught in training programs, resulting in undertrained physicians reading a large percentage of the 40 million ECGs recorded annually. The effective use of simple tools (calipers, ruler, and magnifier) required for crucial measurements and comparisons of intervals requires considerable time for interactive instruction and is difficult to teach in the classroom. The ECGViewer (Blaufuss Medical Multimedia Laboratories, Palo Alto, Calif) program was developed using virtual tools easily manipulated by computer mouse that can be used to analyze archived scanned ECGs on computer screens and classroom projection. Trainees manipulate the on-screen tools from their seats by wireless mouse while the instructor makes corrections with a second mouse, in clear view of the trainees. An on-screen ladder diagram may be constructed by the trainee and critiqued by the instructor. The ECGViewer program has been successfully used and well received by trainees at medical school, residence, and subspecialty fellow level. PMID:16387064

The Study of the Gas-Phase in the CALIFA Galaxies  

NASA Astrophysics Data System (ADS)

A new generation of wide-field surveys based on integral field spectroscopy (IFS) are allowing us to obtain spatially-resolved information of the gas-phase emission in nearby late-type galaxies, based on large samples of regions and full 2D coverage. In particular, the Calar Alto Legacy Integral Field Area survey (CALIFA) is observing a statistically well-defined sample of ~600 galaxies in the local Universe. These observations are allowing us to discover and characterise abundance differentials between galactic substructures and new scaling relations with global physical properties, e.g. a statistical approach to the abundance gradients of spiral galaxies, which indicates a universal radial gradient for oxygen abundance, and improved abundance calibrations for the high-metallicity regime.

Effect of an X-Class Solar Flare on the OI 630 nm Dayglow Emissions  

NASA Technical Reports Server (NTRS)

We present a striking event that shows a prompt effect of an X-class solar flare (X6.2/3B) in the neutral optical dayglow emissions. This flare occurred on 13 December 2001 at 1424 UT and peaked at 1430 UT. The peak-to pre-flare X-ray intensity ratio as observed by GOES-10 was greater than 300 and the EUV flux observed by SEM/SOHO was greater by around 60%. As a response to this flare, the daytime redline (OI 630 nm) column integrated emission intensity measured from Carmen Alto (23.16degS, 70.66degW), in Chile, showed a prompt increase of around 50%. Our results show that this prompt enhancement in the thermospheric dayglow seems to be caused mainly due to an increase in photoelectrons due to a sudden increase in the solar EUV flux associated with this flare.

Psychotherapeutic intervention by telephone  

PubMed Central

Psychotherapy conducted over the telephone has received increasing amounts of empirical attention given practical advantages that side-step treatment barriers encountered in traditional office-based care. The utility and efficacy of telephone therapy appears generalizable across diverse clinical populations seeking care in community-based hospital settings. Treatment barriers common to older adults suggest that telephone therapy may be an efficient and effective mental health resource for this population. This paper describes empirical studies of telehealth interventions and case examples with psychotherapy conducted via telephone on the Spinal Cord Injury Unit of the Palo Alto Veterans’ Administration. Telephone therapy as appears to be a viable intervention with the aging population. PMID:18686761

Software workstations; One-stop shopping for utilities  

SciTech Connect

This paper reports that to help electric utilities use their software more efficiently, California's Electric Power Research Institute (EPRI) has been integrating groups of programs related to common engineering functions - for example, system grounding - into single packages. More than a dozen of these packages are already available. Almost a dozen more, in various stages of development in the Palo Alto institute's technical divisions, are scheduled to be ready between now and 1993. What they offer is one-stop shopping for software solutions. Whether a project involves designing a new transmission line, troubleshooting an equipment problem at a power plant, or planning for future generating needs, utilities have for many years used software to get the job done fast while keeping expenses down. More recent advances in computing power and software engineering have even accelerated the development of programs for utility applications.

Proyecto para la medición sistemática de seeing en CASLEO  

NASA Astrophysics Data System (ADS)

La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

Albedo polarimétrico de asteroides del grupo Hungaria

La región del cinturón de asteroides en donde se encuentra el grupo de los Hungarias (a= 1.79 a 1.98 UA, i=15 a 40 grados) es la única zona donde es común encontrar objetos de tipo taxonómico E, caracterizados por altos albedos, colores relativamente neutros y espectros sin detalles. Este tipo de asteroides está relacionado espectralmente con ciertos meteoritos (aubritas) que indican la existencia de episodios de gran calentamiento que ocurrieron durante la formación del Sistema Solar. Como el espectro de los asteroides de tipo E es idéntico a los de tipo M y P, la única forma de clasificar un asteroide en alguno de estos tres tipos taxonómicos es mediante el albedo. En este trabajo se presentan resultados preliminares sobre la determinación polarimétrica de albedos para objetos de este grupo utilizando el polarímetro CASPROF de CASLEO.

Air Quality Standards for Particulate Matter (PM) at high altitude cities.  

PubMed

The Air Quality Standards for Particulate Matter (PM) at high altitude urban areas in different countries, must consider the pressure and temperature due to the effect that these parameters have on the breath volume. This paper shows the importance to correct Air Quality Standards for PM considering pressure and temperature at different altitudes. Specific factors were suggested to convert the information concerning PM, from local to standard conditions, and adjust the Air Quality Standards for different high altitudes cities. The correction factors ranged from: 1.03 for Santiago de Chile to 1.47 for El Alto Bolivia. Other cities in this study include: Mexico City, México; La Paz, Bolivia; Bogota, Cali and Medellin, Colombia; Quito, Ecuador and Cuzco, Peru. If these corrections are not considered, the atmospheric concentrations will be underestimated. PMID:23202983

Near-infrared calibration systems for precise radial-velocity measurements  

NASA Astrophysics Data System (ADS)

We present work done to prepare two new near-infrared calibration sources for use on high-precision astrophysical spectrographs. Uranium-neon is an atomic calibration source, commercially available as a hollow-cathode lamp, with over 10 000 known emission lines between 0.85 and 4 ?m. Four gas cells — containing C2H2, H13CN, 12CO, and 13CO, respectively—are available as National Institute of Standards and Technology (nist) Standard Reference Materials (SRMs), and provide narrow absorption lines between 1.5 and 1.65 ?m. These calibration sources may prove useful for wavelength-calibrating the future near-infrared high-precision radial-velocity spectrometers, including the Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph (CARMENES),1 the SpectroPolarimetre InfraROUge (SPIRou)?, and the Habitable-Zone Planet Finder (HPF).2

Protection of normal tissues from the cytotoxic effects of radiation therapy: focus on amifostine.  

PubMed

Evidence for the use of amifostine (Ethyol, ALZA Pharmaceuticals, Palo Alto, CA/US Bioscience, West Conshohocken, PA) as a radioprotectant has been gathered in a number of clinical trials conducted over the past decade. This report briefly reviews those trials, as well as highlights results of a recent phase II trial conducted to evaluate the efficacy of daily amifostine administration in reducing the incidence of radiation-induced esophagitis in patients with stage III non-small cell lung cancer. Of 25 patients evaluated, none experienced grade 3 or 4 esophagitis or dyspnea. No patients required discontinuation of therapy due to amifostine-induced hypotension. There was a 60% objective response rate and 1-, 2-, and 3-year survival rates were 55%, 23%, and 23%, respectively. Thus, amifostine administration reduced radiation-induced toxicities without reducing antitumor efficacy. PMID:9794996

New optical polarization measurements of the Crab pulsar  

E-print Network

The Crab nebula and its pulsar have been observed for about 3 hours with the high-speed photo-polarimeter OPTIMA in January 2002 at the Calar Alto 3.5m telescope. The Crab pulsar intensity and polarization are determined at all phases of rotation with higher statistical accuracy than ever. Therefore, we were able to separate the so-called 'off-pulse' phase emission (with an intensity of about 1.2% compared to the main peak, assumed to be present at all phases) from the pulsed emission and show the 'net' polarization of the pulsed structures. Recent theoretical results indicate that the measured optical polarization of the Crab pulsar is similar to expectations from a two-pole caustic emission model or a striped pulsar wind model.

Mapping dust-obscured light in CALIFA galaxies  

NASA Astrophysics Data System (ADS)

The Calar Alto Legacy Integral Field Area (CALIFA) survey is the first and largest survey of its kind, aiming to obtain optical datacubes for 600 nearby (z ˜ 0.01) galaxies. Over 300 objects have already been observed. The spatial and spectral resolutions in CALIFA, combined with its sample size, offer unprecedented good quality data to study spatially resolved dust properties. This work focus on how dust is mapped by the ionised gas. By carefully removing the underlying stellar population, we measure the emission-line Balmer decrement (H?/H?) in different regions in galaxies, separating H II complexes from diffuse emission. We show that the effective dust attenuation measured on an integrated spectrum is underestimated with respect to the effective attenuation on H II regions. This implies that star formation indicators based on optical and UV data should be used with care and may need to be corrected by differential dust attenuation.

Integral Field Spectroscopy of supernova host galaxies  

NASA Astrophysics Data System (ADS)

We used optical Integral Field Spectroscopy of nearby supernova (SN) host galaxies to look for correlations in the environmental parameters at the location of different SN types. Our sample consists of 47 galaxies observed by the Calar Alto Legacy Integrated Field Area (CALIFA) Survey, complemented with other 24 previously observed with the same instrument. We updated the analysis tools implemented in our pilot study (Stanishev et al. 2012) to derive stellar population and ionized gas parameters from the 3D datacubes. According to our results SNe Ib/c explode closer to the galactic core and are more associated with HII regions than SNe II. SNe Ia occur on average farther from the center of the galaxy and are associated with regions with lower current star formation and older stellar populations.

The Disk Mass project; science case for a new PMAS IFU module  

E-print Network

We present our Disk Mass project as the main science case for building a new fiber IFU-module for the PMAS spectrograph, currently mounted at the Cassegrain focus of the 3.5m telescope on Calar Alto. Compared to traditional long-slit observations, the large light collecting power of 2-dimensional Integral Field Units dramatically improves the prospects for performing spectroscopy on extended low surface brightness objects with high spectral resolution. This enables us to measure stellar velocity dispersions in the outer disk of normal spiral galaxies. We describe some results from a PMAS pilot study using the existing lenslet array, and provide a basic description of the new fiber IFU-module for PMAS.

Techniques for reducing fiber-fed and integral-field spectroscopy data: An implementation on R3D  

NASA Astrophysics Data System (ADS)

This paper describes the general characteristics of raw data from fiber-fed spectrographs in general and fiber-fed IFUs in particular. The different steps of the data reduction are presented, and the techniques used to address the unusual characteristics of these data are described in detail. These techniques have been implemented in a specialized software package, R3D, developed to reduce fiber-based integral field spectroscopy (IFS) data. The package comprises a set of command-line routines adapted for each of these steps, suitable for creating pipelines. The routines have been tested against simulations, and against real data from various integral field spectrographs (PMAS, PPAK, GMOS, VIMOS and INTEGRAL). Particular attention is paid to the treatment of cross-talk. Based on observations collected at the Centro Astron?ico Hispano Alemán (CAHA) at Calar Alto, operated jointly by the Max-Planck Institut für Astronomie and the Instituto de Astrofísica de Andalucía (CSIC).

A non-conventional procedure for the 3D modeling of WWI forts  

NASA Astrophysics Data System (ADS)

2014 is the hundredth anniversary of the outbreak of the First World War (WWI) - or Great War - in Europe and a number of initiatives have been planned to commemorate the tragic event. Until 1918, the Italian Trentino - Alto Adige region was under the Austro - Hungarian Empire and represented one of the most crucial and bloody war front between the Austrian and Italian territories. The region borders were constellated of military fortresses, theatre of battles between the two opposite troops. Unfortunately, most of these military buildings are now ruined and their architectures can be hardly appreciated. The paper presents the initial results of the VAST project (VAlorizzazione Storia e Territorio - Valorization of History and Landscape), that aims to digitally reconstruct the forts located on the plateaus of Luserna, Lavarone and Folgaria. An integrated methodology has been adopted to collect and employ all possible source of information in order to derive precise and photo-realistic 3D digital representations of WWI forts.

Drug treatment clients and their community peers: how they differ.  

PubMed

Free-at-Last is a drug treatment program in East Palo Alto, California, a low-income predominantly African American community in Silicon Valley. In this research, a cohort of treatment clients was compared to a random sample of community residents. Both groups used drugs. Two-way analysis of variance was used to identify factors that predicted the number of drugs used, controlling for client or community sample status. Significant predictors turned out to be perception of race discrimination, ever selling drugs, contact with the police, the number of relatives who died suddenly as a juvenile, ever having thoughts of suicide, and marital status. Path analysis was used to show the relationship between predictors of the number of drugs used for treatment clients; a second path was done for community clients. By comparing each path analysis, we were able to show how treatment clients arrived at significantly higher drug use than peers in the community. PMID:20509083

Measurement of precipitation induced FUV emission and Geocoronal Lyman Alpha from the IMI mission  

NASA Technical Reports Server (NTRS)

This final report describes the activities of the Lockheed Martin Palo Alto Research Laboratory in studying the measurement of ion and electron precipitation induced Far Ultra-Violet (FUV) emissions and Geocoronal Lyman Alpha for the NASA Inner Magnetospheric Imager (IMI) mission. this study examined promising techniques that may allow combining several FUV instruments that would separately measure proton aurora, electron aurora, and geocoronal Lyman alpha into a single instrument operated on a spinning spacecraft. The study consisted of two parts. First, the geocoronal Lyman alpha, proton aurora, and electron aurora emissions were modeled to determine instrument requirements. Second, several promising techniques were investigated to determine if they were suitable for use in an IMI-type mission. Among the techniques investigated were the Hydrogen gas cell for eliminating cold geocoronal Lyman alpha emissions, and a coded aperture spectrometer with sufficient resolution to separate Doppler shifted Lyman alpha components.

An assessment of the Tongonan geothermal reservoir, Philippines, at high-pressure operating conditions  

SciTech Connect

An evaluation of the Tongonan geothermal reservoir was conducted to improve the power recovery through reservoir and process optimization. The performance of the existing production wells was reviewed and the response of the field based on the anticipated production levels was simulated at various operating conditions. The results indicate that the Tongonan geothermal reservoir can be exploited at a high pressure operating condition with substantial improvement in the field capacity. The authors calculate that the Upper Mahiao and the Malitbog sectors of the Tongonan field are capable of generating 395 MWe at 1.0 MPa abs., on top of the existing 112.5 MWe plant, compared with 275 MWe if the field is operated at 0.6 MPa abs. The total capacity for the proposed Leyte A 640 MWe expansion can be generated from these sectors with the additional power to be tapped from Mahanagdong and Alto Peak sectors.

These are limitations that have prevented (until now) carrying out a detailed study of the evolution of the SFR by components (nuclei, bulges, disks), even locally. This kind of studies are key, for example, for understanding how galaxies really evolve from the Blue Cloud to the Red Sequence. We will first discuss in detail the validity of the assumption that the SFR given by the extincion-corrected H$\\alpha$ is a good measure of the total SFR by means of cross-comparing this with other SFR estimators, namely the integrated UV...

The COMET-AR User's Manual provides a reference manual for the Computational Structural Mechanics Testbed with Adaptive Refinement (COMET-AR), a software system developed jointly by Lockheed Palo Alto Research Laboratory and NASA Langley Research Center under contract NAS1-18444. The COMET-AR system is an extended version of an earlier finite element based structural analysis system called COMET, also developed by Lockheed and NASA. The primary extensions are the adaptive mesh refinement capabilities and a new "object-like" database interface that makes COMET-AR easier to extend further. This User's Manual provides a detailed description of the user interface to COMET-AR from the viewpoint of a structural analyst.

The complex ecology of hantavirus in Paraguay.  

PubMed

Following an outbreak of hantavirus pulmonary syndrome (HPS) in the Paraguayan Chaco in 1995, Calomys laucha was identified as the rodent host for the hantavirus associated with these cases. To explore the possibility of additional hantaviruses in Paraguay, we collected 636 mammals from 10 of the 17 departments. Plasma from 27 animals in Alto Paraguay and Boquer6n in the Chaco and Neembucú and Itapúa in the eastern region had antibody to Andes virus antigens. Of these 27, five individuals (among four species) were positive for hantavirus RNA. Sera were collected from indigenous people in eastern Paraguay to ascertain whether persons were being infected with hantavirus outside of the Chaco. Seventeen percent were antibody-positive. These results suggest that several different hantaviruses are co-circulating in Paraguay, and that HPS cases occurring in eastern Paraguay may result from exposure to hantaviruses that are distinct from those in the Chaco.

Lockheed Solar Observatory and the Discovery of Moreton-Ramsey Waves  

NASA Astrophysics Data System (ADS)

Moreton Waves are high-speed disturbances seen traveling away from large solar flares in H-alpha movies of the solar chromosphere. They were discovered by the observer Harry Ramsey in the late 1950s, and then published and publicized by the director Gail Moreton, both of the Lockheed Solar Observatory in the Hollywood Hills of Southern California. These efforts established the scientific reputation and secured continuing funding of the observatory, whose present-day successor is the Lockheed Martin Solar and Astrophysics Lab in Palo Alto. Moreton waves are rare, and there was limited interest in them until the EIT instrument on SOHO began seeing large numbers of similar waves in the corona in the late 1990s. The exact relation between the two observations is still a research topic today. This talk will describe some of the history of the observatory and the discovery and early interpretation of the waves.

Vibrational mode shapes in Caribbean steelpans. I. Tenor and double second.  

PubMed

Vibrational mode shapes have been studied in several tenor (soprano range) and double-second (alto range) steelpans by three well-known makers. Normal modes are determined from operating deflection shapes recorded by means of electronic TV holography. Vibrational modes of the various note areas are designated by the number of radial and circumferential nodal lines. Tuners generally tune one mode an octave above the fundamental and, if possible, a third mode is tuned either a twelfth or two octaves above the fundamental. Note dimensions follow an approximate scaling law L=Kf(213), and the larger note areas can be roughly modeled as rectangular plates with simply supported edges. Modal shapes in the skirt correspond to standing bending waves propagating around the ring. PMID:10955647

Palynology as an age-control tool for ice cores. First results of PAMOGIS - Pollen Analyses of the Mt. Ortles Glacier Ice Samples  

NASA Astrophysics Data System (ADS)

Glacier ice cores from the mid latitude are capable of retaining essential information on past climate, environmental and human activities on a seasonal/annual time resolution. However, for a correct interpretation of the ice record a good chronological control is essential. Absolute time markers such as 3H peaks and Sahara dust horizons, together with radiometric methods such as 210Pb, radiocarbon from carbonaceous aerosol particles and AMS-dating are commonly used to obtain the age depth model of ice cores. In this frame we present the first pollen-based chronology from the Eastern Alps. Results of pollen analyses performed on a 10 m firn core taken on the top of Alto dell'Ortles Glacier (3905 m a.s.l.) will be discussed. Palynological data are compared and complemented with stable isotopes, major ions and trace elements analyses. Based on the single species flowering periods, our results show that the pollen spectrum presents seasonal and inter-annual variability that enables to distinguish snow accumulated in the three different flowering seasons and winter snow. According to these four components a seasonal and annual chronology was established, proving that the 10 m firn core encompasses four years of snow accumulation and presents a clear seasonal palynological signal. These first results reveal the potential of pollen content of glacier snow and ice as a chronological tool that can contribute to the construction of a robust chronological model with a seasonal to annual resolution. This study is the first step and the base for future research on deeper ice cores on the Alto dell'Ortles Glacier (Ortles project: www.ortles.org).

The O-type eclipsing contact binary LY Aurigae - member of a quadruple system  

NASA Astrophysics Data System (ADS)

The eclipsing binary LY Aur (O9 II + O9 III) belongs to the rare class of early-type contact systems. We obtained 23 new spectra at the Ond?ejov and Dominion Astrophysical Observatories, which were analysed with four older Calar Alto and one ELODIE archive spectra. A new result of this study is that the visual companion of LY Aur - the spectral lines of which are clearly seen in our spectra - is also an SB1 binary having an orbital period of 20.46d, an eccentric orbit, and a radial velocity semi-amplitude of 33 km s-1. The H? line blend contains an emission component, which shows dependence on the orbital phase of the eclipsing system, with the strongest emission around the secondary eclipse. Revised elements of the eclipsing binary and the orbital solution of the companion binary are determined from our set of spectra and new light-curve solutions of the eclipsing pair. The mass of the primary of 25.5 M? agrees well with its spectral type, whereas the secondary mass of 14 M? is smaller than expected. From an O-C analysis of the minimum times of LY Aur that span more than 40 years, we found that the orbital period is decreasing, indicating the presence of interaction processes. The system is likely in a phase of non-conservative mass exchange. Based on spectral observations collected at the German-Spanish Observatory, Calar Alto, Spain; Dominion Astrophysical Observatory, Canada; Ond?ejov Observatory, Czech Republic, and an archival Haute Provence Observatory ELODIE spectrum.

During October and November of 1983...Recientes sumarios de la distribución de los manaties amazónicos Trichechus inunguis registran especimenes de la mayor parte de la cuenca amazónica en Brasil, el oriente de Peru, y el suroriente de Colombia, pero no de Ecuador. Durante octubre y noviembre de 1983 nosotros fuimos en busca de manaties en los sistemas de los rios Aguarico y Cuyabeno de la Provincia del Napo, Ecuador oriental. Aqui documentamos la existencia de manaties amazónicos en Ecuador, proveemos estimaciones aproximadas de su actual distribución, describimos varios aspectos de su ecologia en Ecuador, documentamos el uso de manaties por gentes indigenas, y documentamos la cosecha comercial actual de manaties para carne. Manaties feuron observados por nosotros en varias localidades separadas en las tierras bajas del Ecuador oriental. Adicionalmente, reportamos varias observaciones por otros, asi como tambien registros históricos publicados que fueron previamente pasados por alto. Nuestras observaciones de manaties son de habitaciones en aguas negras en selva iluviosa primaria no alterada de tierras bajas, en aguas con un pH de 5.5 a 6.0 y temperatura de 25.0 a 30.7C. En la región del alto Cuyabeno, los indios de la tribu Siona, quienes han cosechado manaties por generaciones, se han impuesto asi mismos prohibiciones en la caza de manaties en Ecuador y tierras adyacentes de Peru. La mayoria de la carne obtenida es usada por los militares ya sea ecuatorianos o peruanos. Nosotros encontramos abundantes manaties sólo en una localidad, la Laguna Lagarto Cocha. Sin embargo, esta población esta siendo activamente cazada, y la carne es vendida a los destacamentos militares del lugar. Estimamos que si el nivel actual de caza continua al mismo ritmo los manaties amazónicos habran desaparecido del Ecuador en unos 10 a 15 anios....

XMS and NG1dF: extreme multiplex spectrographs for wide-field multi-object spectroscopy  

NASA Astrophysics Data System (ADS)

Two feasibility studies for spectrographs that can deliver at least 4000 MOS slits over a 1° field at the prime focuses of the Anglo-Australian and Calar Alto Observatories have been completed. We describe the design and science case of the Calar Alto eXtreme Multiplex Spectrograph (XMS) for which an extended study, half way between feasibility study and phase-A, was made. The optical design is quite similar than in the AAO study for the Next Generation 1 degree Field (NG1dF) but the mechanical design of XMS is quite different and much more developed. In a single night, 25000 galaxy redshifts can be measured to z~0.7 and beyond for measuring the Baryon Acoustic Oscillation (BAO) scale and many other science goals. This may provide a low-cost alternative to WFMOS for example and other large fibre spectrographs. The design features four cloned spectrographs which gives a smaller total weight and length than a unique spectrograph to makes it placable at prime focus. The clones use a transparent design including a grism in which all optics are about the size or smaller than the clone rectangular subfield so that they can be tightly packed with little gaps between subfields. Only low cost glasses are used; the variations in chromatic aberrations between bands are compensated by changing a box containing the grism and two adjacent lenses. Three bands cover the 420nm to 920nm wavelength range at 10A resolution while another cover the Calcium triplet at 3A. An optional box does imaging. We however also studied different innovative methods for acquisition without imaging. A special mask changing mechanism was also designed to compensate for the lack of space around the focal plane. Conceptual designs for larger projects (AAT 2º field, CFHT, VISTA) have also been done.

Evaluation of artificial recharge in the Mojave River Ground-Water Basin, California  

USGS Publications Warehouse

The Mojave River Basin relies almost entirely on ground water to meet the needs of its growing population and agriculture, which has resulted in overdraft conditions. Some of the ground-water management alternatives being proposed to mitigate the effects of overdraft include artificial recharge using water from the California State Water Project (SWP) and using SWP water in lieu of ground-water pumpage. A calibrated ground-water flow model was used to evaluate six proposed water-management alternatives using SWP water during a 20-year simulation period, 2000-2019, using constant rates from 1999 for recharge and pumpage (with the exception of recharge derived from Mojave River streamflows which were variable). The measured streamflow for the period of 1970-1989 was used to simulate the Mojave River streamflow. Water-management alternative 1 assumed that none of the Mojave Water Agency allocation of SWP water was available for mitigation measures and resulted in increases in hydraulic head in the floodplain aquifer in years of above-average streamflow (2008-2010, 2013) and decreases in years of below average streamflow. In general, simulated hydraulic heads in the regional aquifer declined with the exception of the El Mirage and Harper Lake areas. Also, average storage depletion for the entire ground-water basin over the 20-year simulation was 40,940 acre-feet per year. Water-management alternative 2 assumed that 30,000 acre-feet per year of SWP water was artificially recharged at Rock Springs Road Outlet (RSO). By 2019, the simulated hydraulic heads were as much as 75 feet higher in the Alto at the recharge site, 24 feet higher in the Transition zone, 15 feet higher in the Centro, and 17 feet higher in the Baja model subareas than the hydraulic heads resulting from water-management alternative 1. Water-management alternative 2 affected simulated hydraulic heads by as much as 5 feet in an area totalling 290 square miles; most of the change occurred in the Alto and Baja model subareas. Average storage depletion for water-management alternative 2 for the entire ground-water basin for the 20-year simulation period was 15,880 acre-feet per year, 25,060 acre-feet per year less than water-management alternative 1. Also, water-management alternative 2 indicated that the artificial recharge at RSO resulted in less simulated ground-water recharge from stream leakage in the Alto model subarea, which led to greater streamflow at the Lower Narrows, Barstow, and Afton Canyon streamflow gages. This increased streamflow resulted in an increase in simulated ground-water recharge from stream leakage, primarily in the Centro and Baja model subareas. Water-management alternative 3 assumed that 4,000 acre-feet per year of SWP water was artificially recharged at Manzanita and Oro Grande Washes (a total of 8,000 acre-feet per year) in the Alto model subarea. By 2019, the simulated hydraulic heads beneath the recharge sites were as much as 278 feet higher than heads resulting from water-management alternative 1. Changes in simulated hydraulic head greater than 5 feet covered almost 138 square miles in the Alto model subarea. Water-management alternative 3 had little effect on simulated hydraulic heads in the other model subareas. Model results indicated that the average storage depletion for the entire ground-water basin during the 20-year simulation was 32,940 acre-feet per year, about 8,000 acre-feet per year less than water-management alternative 1. Water-management alternative 3 had essentially no effect on simulated streamflows during the 20-year simulation period and, therefore, little effect on simulated net stream leakage. Water-management alternative 4 assumed 10,000 acre-feet per year of SWP water was artificially recharged near Newberry Springs in the Baja subarea. By 2019, the simulated hydraulic heads beneath the recharge site were as much as 193 ft higher in the Baja model subarea than the hydraulic heads res

The Tempo of Recent Volcanism on Terceira, Azores  

NASA Astrophysics Data System (ADS)

Terceira is an active volcanic island with offshore eruptions recorded in the 19th and 20th centuries. It is constructed by three main volcanic centres aligned along a NW-SE-trending fissure zone. Eruptions from vents along this main fissure zone are a persistent feature in the island's history, including the two recent offshore eruptions in 1867 and 1995-2002, and the 1761 basaltic eruption, the only recorded historic event on the island that has been inhabited since about 1485 AD. Early work [1] on the volcanic succession of the island established a stratigraphic sequence for the Upper Terceira Group (UTG), the on-land products of the past ~ 20,000 years of volcanism, with very little chronological control. Since then, two more studies have added detail on the timing of eruptions in the UTG and the older history of the island, including ignimbrite-forming eruptions and volcano-building lavas, using both 14C and 40Ar/39Ar dating [2, 3]. Further age determinations have been made and are reported here together with a reassessment of the stratigraphic significance of some of the ages obtained in the past. We present here an estimate of the number and type of eruptions in the UTG, concentrating on the last 3,000 years. Ignimbrite-forming eruptions have not occurred since one or two events took place 20-23,000 years ago [3] from the northern caldera of the Pico Alto-Guilherme Moniz volcanic centre, the middle of the three main central volcanoes. The Santa Barbara composite volcano has a record of 12-14 eruptions over the past three millennia; all but one formed comendite-pantellerite lava domes and coulées, of which three were preceded by explosive sub-plinian phases forming tephra-fall deposits. One flank eruption formed a basaltic scoria cone and lava flow. In approximately the same time period, Pico Alto-Guilherme Moniz produced 11-14 eruptions from the northern caldera (Pico Alto), all of which formed comendite-pantellerite lava domes and coulées, with one or two preceded by explosive sub-plinian phases. Uncertainty in the number of eruptions is due to lack of knowledge about the number of events contributing to some of the complex clusters of lava domes. The fissure zone hosted 6-7 basaltic-intermediate scoria/spatter cone and lava-forming eruptions during the past 3,000 years, and one event that formed comenditic trachyte lava domes. Thus, Terceira's volcanoes contribute to a rapid tempo of volcanism, having recently produced an eruption approximately every century, but clustering is evident in the chronological record. Interestingly, there is no reported historic on-land eruption in the ~ 300 years between colonization and 1761. We hope to improve our understanding of the tempo of volcanism on Terceira as more age determinations are performed. Furthermore, it is known that there are more eruptive units than accounted for in the UTG stratigraphy, thus the numbers of events must be considered a minimum.

The Cariris Velhos tectonic event in Northeast Brazil  

NASA Astrophysics Data System (ADS)

The Borborema Province in northeastern South America is a typical Brasiliano-Pan-African branching system of Neoproterozoic orogens that forms part of the Western Gondwana assembly. The province is positioned between the São Luis-West Africa craton to the north and the São Francisco (Congo-Kasai) craton to the south. For this province the main characteristics are (a) its subdivision into five major tectonic domains, bounded mostly by long shear zones, as follows: Médio Coreaú, Ceará Central, Rio Grande do Norte, Transversal, and Southern; (b) the alternation of supracrustal belts with reworked basement inliers (Archean nuclei + Paleoproterozoic belts); and (c) the diversity of granitic plutonism, from Neoproterozoic to Early Cambrian ages, that affect supracrustal rocks as well as basement inliers. Recently, orogenic rock assemblages of early Tonian (1000-920 Ma) orogenic evolution have been recognized, which are restricted to the Transversal and Southern domains of the Province. Within the Transversal Zone, the Alto Pajeú terrane locally includes some remnants of oceanic crust along with island arc and continental arc rock assemblages, but the dominant supracrustal rocks are mature and immature pelitic metasedimentary and metavolcaniclastic rocks. Contiguous and parallel to the Alto Pajeú terrane, the Riacho Gravatá subterrane consists mainly of low-grade metamorphic successions of metarhythmites, some of which are clearly turbiditic in origin, metaconglomerates, and sporadic marbles, along with interbedded metarhyolitic and metadacitic volcanic or metavolcaniclastic rocks. Both terrane and subterrane are cut by syn-contractional intrusive sheets of dominantly peraluminous high-K calc-alkaline, granititic to granodioritic metaplutonic rocks. The geochemical patterns of both supracrustal and intrusive rocks show similarities with associations of mature continental arc volcano-sedimentary sequences, but some subordinate intra-plate characteristics are also found. In both the Alto Pajeú and Riacho Gravatá terranes, TIMS and SHRIMP U-Pb isotopic data from zircons from both metavolcanic and metaplutonic rocks yield ages between 1.0 and 0.92 Ga, which define the time span for an event of orogenic character, the Cariris Velhos event. Less extensive occurrences of rocks of Cariris Velhos age are recognized mainly in the southernmost domains of the Province, as for example in the Poço Redondo-Marancó terrane, where arc-affinity migmatite-granitic and meta-volcano-sedimentary rocks show U-Pb ages (SHRIMP data) around 0.98-0.97 Ga. For all these domains, Sm-Nd data exhibit TDM model ages between 1.9 and 1.1 Ga with corresponding slightly negative to slightly positive ?Nd( t) values. These domains, along with the Borborema Province as a whole, were significantly affected by tectonic and magmatic events of the Brasiliano Cycle (0.7-0.5 Ga), so that it is possible that there are some other early Tonian rock assemblages which were completely masked and hidden by these later Brasiliano events. Cariris Velhos processes are younger than the majority of orogenic systems at the end of Mesoproterozoic Era and beginning of Neoproterozoic throughout the world, e.g. Irumide belt, Kibaride belt and Namaqua-Natal belt, and considerably younger than those of the youngest orogenic process (Ottawan) in the Grenvillian System. Therefore, they were probably not associated with the proposed assembly of Rodinia. We suggest, instead, that Cariris Velhos magmatism and tectonism could have been related to a continental margin magmatic arc, with possible back-arc associations, and that this margin may have been a short-lived (<100 m.y.) leading edge of the newly assembled Rodinia supercontinent.

A high altitude paleoclimate record from an ice core retrieved at the northern margin of the Mediterranean basin  

NASA Astrophysics Data System (ADS)

Atmospheric temperatures in the Alps are increasing at twice the global rate and this change may be amplified at the highest elevations. There is a scarcity of paleo-climate information from high altitudes to place this current rapid climate change in a paleo-perspective. The 'Ortles Project' is an international scientific effort gathering institutes from six nations with the primary goal of obtaining a high altitude paleo-climate record in the Mediterranean area. In 2011 four ice cores were extracted from Alto dell'Ortles (3859 m, South Tyrol, Italy) the highest glacier in the eastern Alps. This site is located ~30 km away from where the famous ~5.2 kyr old Tyrolean Ice Man was discovered emerging from an ablating ice field (Hauslabjoch, 3210 m) in 1991. The good state of conservation of this mummy suggested that the current warming trend is unprecedented in South Tyrol during the late Holocene and that unique prehistoric ice was still present in this region. During the ice core drilling operations we found that the glacier Alto dell'Ortles shows a very unusual thermic behavior as it is transitioning from a cold to a temperate state. In fact, below a 30 meter thick temperate firn portion, we observed cold ice layers sitting on a frozen bedrock (-2.8 C). These represent remnants of the colder climate before ~1980 AD, when an instrumental record indicates a ~2 C lower temperature in this area during the period 1864-1980 AD. By analyzing one of the Ortles cores for stable isotopes, dust and major ions, we found an annually preserved climatic signal embedded in the deep cold ice of this glacier. Alto dell'Ortles is therefore the first low-accumulation (850 mm w.e. per year) alpine drilling site where both winter and summer layers can be identified. Preliminary annual layer counting and two absolute time markers suggest that the time period covered by the Ortles ice cores spans from several centuries to a few millennia. In particular, a Larix (larch) leaf discovered at 74 m depth suggests a 14C bottom ice age of 2664 ×166 years (early European Iron Age) supporting the idea that exceptional prehistoric ice is still present at the highest elevations of South Tyrol. Here we present the records of the first Ortles core analyzed in terms of ?18O (proxy of mid-tropospheric temperature), major ions and dust. We found that ?18O measured in the shallowest layers of this glacier exceeds the average deeper values indicating that the Ortles cores capture the recent increase in atmospheric temperatures at high elevation and that this is anomalous over a time scale that extends from hundreds to thousands of years.

CARMENES instrument overview  

NASA Astrophysics Data System (ADS)

This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions. The scientific goal of the project is conducting a 600-night exoplanet survey targeting ~ 300 M dwarfs with the completed instrument. The CARMENES instrument consists of two separate echelle spectrographs covering the wavelength range from 0.55 to 1.7 ?m at a spectral resolution of R = 82,000, fed by fibers from the Cassegrain focus of the telescope. The spectrographs are housed in vacuum tanks providing the temperature-stabilized environments necessary to enable a 1 m/s radial velocity precision employing a simultaneous calibration with an emission-line lamp or with a Fabry-Perot etalon. For mid-M to late-M spectral types, the wavelength range around 1.0 ?m (Y band) is the most important wavelength region for radial velocity work. Therefore, the efficiency of CARMENES has been optimized in this range. The CARMENES instrument consists of two spectrographs, one equipped with a 4k x 4k pixel CCD for the range 0.55 - 1.05 ?m, and one with two 2k x 2k pixel HgCdTe detectors for the range from 0.95 - 1.7?m. Each spectrograph will be coupled to the 3.5m telescope with two optical fibers, one for the target, and one for calibration light. The front end contains a dichroic beam splitter and an atmospheric dispersion corrector, to feed the light into the fibers leading to the spectrographs. Guiding is performed with a separate camera; on-axis as well as off-axis guiding modes are implemented. Fibers with octagonal cross-section are employed to ensure good stability of the output in the presence of residual guiding errors. The fibers are continually actuated to reduce modal noise. The spectrographs are mounted on benches inside vacuum tanks located in the coudé laboratory of the 3.5m dome. Each vacuum tank is equipped with a temperature stabilization system capable of keeping the temperature constant to within +/-0.01°C over 24 hours. The visible-light spectrograph will be operated near room temperature, while the near-IR spectrograph will be cooled to ~ 140 K. The CARMENES instrument passed its final design review in February 2013. The MAIV phase is currently ongoing. First tests at the telescope are scheduled for early 2015. Completion of the full instrument is planned for the fall of 2015. At least 600 useable nights have been allocated at the Calar Alto 3.5m Telescope for the CARMENES survey in the time frame until 2018. A data base of M stars (dubbed CARMENCITA) has been compiled from which the CARMENES sample can be selected. CARMENCITA contains information on all relevant properties of the potential targets. Dedicated imaging, photometric, and spectroscopic observations are underway to provide crucial data on these stars that are not available in the literature.

Distance, structure and bright stellar content of the dwarf irregular galaxy UGC 685  

E-print Network

B,R, and J frames taken with the Calar Alto 3.5m telescope of the dwarf irregular galaxy UGC 685 are presented. The brightest part of the stellar population is resolved in B and R, very few also in J. The stellar color-magnitude diagram is discussed. An estimate of the distance to UGC 685 of 5.5 Mpc is derived based on the brightest blue supergiant stars. Most of the resolved bright stars show colors in the range $-0.1 \\le B-R \\le +0.7$. The continuum light of the unresolved stars is distributed rather regular in B, R, and J, showing only minor irregularities. This surface brightness distribution follows an exponential law in all three colors with a scale length $r_c = 0.33$ kpc. The central surface brightnesses are $21.57 \\pm 0.09 mag/\\Box''$, $20.65 \\pm 0.06mag/\\Box''$, and $20.11 \\pm 0.11 mag/\\Box''$, in B, R, and J, respectively. The surface brightness can be traced out to 5 $r_c$ in B and R. Thus, UGC 685 belongs to the class of dwarfs where the HI distribution is much more extended (here 2.6 times) than the optical (stellar) light distribution, but contrary to many objects of this type, it does not belong to the class of low-surface brightness objects. The overall colors are $B-R = + 0.97$, $B-J = +1.55$ and the magnitude is B = 14.55 ($M_B^o$ = -14.5). The classification as an irregular dwarf results from the few HII regions of UGC 685. On an H${\\alpha}$ Calar Alto 2.2m telescope CCD image, I identified only 5 HII regions. The total H${\\alpha}$ flux corresponds to a mildly on-going star formation with a rate of 0.003 \\Msolar yr$^{-1}$, a low rate even in comparison to other dwarfs. The available data do not indicate any major deviation from this rather low star formation rate within the last $10^9$ yr.

Interaction between regional and local tectonic forcing along a complex Quaternary extensional basin: Upper Tiber Valley, Northern Apennines, Italy  

NASA Astrophysics Data System (ADS)

In extending areas undergoing regional tectonic uplift, the persistence of subsidence at a normal-fault hanging-wall depends on the competition between regional and local tectonic effects. When regional uplift exceeds the subsidence of the hanging-wall block, denudation prevails at both the hanging-wall and the foot-wall. When local tectonic subsidence exceeds regional uplift, sedimentation occurs over the hanging-wall block, supplied by foot-wall erosion. We analyzed a Pliocene-Quaternary continental basin, currently crossed by the Tiber River in Italy. The tectono-sedimentary evolution of the basin developed at the hanging-wall of a regional low-angle extensional detachment, the Alto Tiberina Fault, in the axial region of the Northern Apennines of Italy. This area is affected by regional uplift on the order of 0.5-1.0 mm/yr. The present-day activity of the fault is revealed by both microseismicity and geodetic (GPS) data. We investigated the mid- (10-100 ka) and long-term (0.5-3.0 Ma) evolution of the three depocenters by studying the continental Pleistocene succession infilling the basin as well as fluvial terraces and higher paleosurfaces carved into the Pleistocene deposits. By using surficial geologic data and an interpretation of a set of seismic reflection profiles, we show that the three depocenters experienced a fairly similar evolution during the Pliocene-Early Pleistocene, when a 1000-m-thick continental succession was deposited. On the contrary, geomorphological observations indicate that, at the beginning of the Middle Pleistocene, a switch occurred in the evolution of the three depocenters. In the northernmost Sansepolcro sub-basin, bounding normal faults are active and hanging-wall subsidence outpaces regional uplift. Concurrently, in the Umbertide and Ponte Pattoli sub-basins uplift dominates over the hanging-wall subsidence, promoting river incision and exhumation of the Pleistocene deposits. For these two depocenters, by means of terrace-river correlations, we estimate that the incision rate is ?0.3-0.35 mm/yr, suggesting a maximum tectonic subsidence of 0.2 mm/yr. The identification of a heterogeneous uplift pattern along the hanging-wall of the Alto Tiberina Fault, driven by different displacement rates of its fault splays, allowed us to characterize fault segments with different activities and, possibly, different seismic behaviors.

Rigorous noise test and calibration check of strong-motion instrumentation at the Conrad Observatory in Austria.  

NASA Astrophysics Data System (ADS)

In the framework of the European InterregIV Italy/Austria project: "HAREIA - Historical and Recent Earthquakes in Italy and Austria" the Central Institute for Meteorology and Geodynamics (ZAMG) and Mathematic and Geosciences Department of University of Trieste (DMG) are upgrading the transfrontier seismic network of South-Eastern Alps with new 12 accelerometric stations to enhance the strong motion instrument density near the Austria/Italy border. Various public institutions of the provinces Alto Adige (Bolzano Province), Veneto (ARPAV) and Friuli Venezia Giulia (Regional Civil Defense) in Italy and in the Austrian province of Tyrol are involved in the project. The site selection was carried out to improve the present local network geometry thus meeting the needs of public Institutions in the involved regions. In Tyrol and Alto Adige some strategic buildings (hospitals and public buildings) have been selected, whereas in Veneto and Friuli Venezia Giulia the sites are in the free field, mainly located near villages. The instruments will be installed in an innovative box, designed by ZAMG, that provides electric and water isolation. The common choice regarding the instrument selection has been the new Kinemetrics Basalt ® accelerograph to guarantee homogeneity with the already installed instrumentation and compatibility with the software already in use at the different seismic institutions in the area. Prior to deployment the equipment was tested at the Conrad Observatory and a common set-up has been devised. The Conrad Observatory, seismically particularly quiet, permits to analyze both the sensor and the acquisition system noise. The instruments were connected to the network and the data sent in real-time to the ZAMG data center in Vienna and the DMG data center in Trieste. The data have been collected in the database and analyzed using signal processing modules PQLX and Matlab. The data analysis of the recordings at the ultra-quiet Conrad Observatory pointed out some differences in the seismic response of the 12 instruments, mainly within the tolerance stated by the factory, and an optimization of a few sensors can be carried out in order to guarantee compatible high quality measurements.

Fog Collection and Sustainable Architecture in Atacama Coast  

NASA Astrophysics Data System (ADS)

It is imperative to integrate renewable energy and climate into zero-carbon buildings in arid lands, particularly when it is reinforced by natural and social science-based innovation in natural and built environs. The aim is twofold: On one hand, to establish potential natural and urban habitats and their yields required in different scales of intervention and, on another hand, augment rate and yield of fog collection used for drinking and irrigation in chosen locations. The purpose of this study is to integrate zero-carbon energy, landscape and sustainable architecture as a whole and thus envision potential inhabitation through self-sufficient space-frame configurations along the coast of Tarapacá Region in Chile. In a sequential way, this study distinguishes three scales of interventions: A. Territorial scale. It consists of rural and natural zones along the shore of Tarapacá Region: Fog oases, creeks or corridors. The strategic allocation of large fog collectors can bring local agriculture back and thus stop rural emigration; and also repair existing fragile ecosystems in several fog oases by harvesting and distributing mainly crop water. B. Local scale. The space-frame fog collectors are allocated in Alto Patache (fog oasis) and Iquique city (low-income sprawl of Alto Hospicio). These artefacts can supply both water and electricity to small communities through forestation, sustainable micro-agriculture and complementary electrification. C. Domestic scale. It consists of the design of autonomous housing configuration based in polygonal space-frames. This inhabitable unit is modular, deployable and lightweight; with an adjustable polyvalent membrane which performs as water repellent skin (facing South and SW winds) and shading device facing Equator. In addition, a domestic wind turbine is installed within the structural frame to provide autonomous electrification. Water collector, filtering (purification) and irrigation network is designed with available materials and local techniques. This research integrates climatic, structural and constructional factors by employing agile space-frame configurations; implementing appropriate low-passive energy technologies and testing hydrophobic and durable fabrics. The overall design target will upgrade the following aspects: 1. Increasing rate and yield of advection fog that can be anticipated from the fog harvesting rate and the uncertainty of climatic conditions 2. Structural reinforcement of fog collectors through lightweight, modular and deployable space-frames 3. Reducing installation and maintenance of fog collection 4. Purification of drinking water due to concentrations of pollutants 5. Lowering frame impacts on ground and surrounding mainly in lomas The methods mainly consists of literature review; fieldwork; comparative analysis of existing fog collection’s techniques and climatic design simulations.

Mesoproterozoic rapakivi granites of the Rondonia Tin Province, southwestern border of the Amazonian craton, Brazil-I. Reconnaissance U-Pb geochronology and regional implications  

USGS Publications Warehouse

Rapakivi granites and associated mafic and ultramafic rocks in the Rondonia Tin Province, southwestern Amazonian craton, Brazil were emplaced during six discrete episodes of magmatism between ca 1600 and 970 Ma. The seven rapakivi granite suites emplaced at this time were the Serra da Providencia Intrusive Suite (U-Pb ages between 1606 and 1532 Ma); Santo Antonio Intrusive Suite (U-Pb age 1406 Ma); Teotonio Intrusive Suite (U-Pb age 1387 Ma); Alto Candeias Intrusive Suite (U-Pb ages between 1346 and 1338 Ma); Sao Lourenco-Caripunas Intrusive Suite (U-Pb ages between 1314 and 1309 Ma); Santa Clara Intrusive Suite (U-Pb ages between 1082 and 1074 Ma); and Younger Granites of Rondonia (U-Pb ages between 998 and 974 Ma). The Serra da Providencia Intrusive Suite intruded the Paleoproterozoic (1.80 to 1.70 Ga) Rio Negro-Juruena crust whereas the other suites were emplaced into the 1.50 to 1.30 Ga Rondonia-San Ignacio crust. Their intrusion was contemporaneous with orogenic activity in other parts of the southwestern Amazonian craton, except for the oldest, Serra da Providencia Intrusive Suite. Orogenic events coeval with emplacement of the Serra da Providencia Intrusive Suite are not clearly recognized in the region. The Santo Antonio, Teotonio, Alto Candeias and Sao Lourenco-Caripunas Intrusive Suites are interpreted to represent extensional anorogenic magmatism associated with the terminal stages of the Rondonian-San Ignacio orogeny. At least the Sao Lourenco-Caripunas rapakivi granites and coeval intra-continental rift sedimentary rocks may, in contrast, represent the products of extensional tectonics and rifting preceding the Sunsas/Aguapei orogeny (1.25 to 1.0 Ga). The two youngest rapakivi suites, the Santa Clara Intrusive Suite and Younger Granites of Rondonia, seemingly represent inboard magmatism in the Rondonian-San Ignacio Province during a younger episode of reworking in the Rio Negro-Juruena Province during the waning stages of the collisional 1.1 to 1.0 Ga Sunsas/Aguapei orogeny. The six intra-plate rapakivi granite episodes in the southwestern part of the Amazonian craton form three broad periods of anorogenic magmatism that have age-correlative events composed of similar rocks and geologic environments in eastern Laurentia and Baltica, although the exact timing of magmatism appears slightly different. Recognition of lithologic and chronological correlations between various cratons provide important constraints to models explaining the interplay between rapakivi granite magmatism and deep crustal evolution of an early Mesoproterozoic supercontinent. They are, furthermore, important to plate tectonic models for the assembly, dispersal and reassembly of Amazonia, Laurentia and Baltica in the Mesoproterozoic and Neoproterozoic.

Deep structure of a stretched lithosphere: Magnetotelluric imaging of the southeastern Borborema province, NE Brazil  

NASA Astrophysics Data System (ADS)

Magnetotelluric data were collected at 25 stations along a NNW-SSE linear profile deployed perpendicularly to the main structures in the southeastern portion of the Borborema province, northeast Brazil. The geotectonic scenario is characterized by a broad range of tectomagmatic events including periods of compressive tectonism associated with amalgamation of lithospheric blocks during the Brasiliano orogeny in the Late Neoproterozoic, superimposed by extensional events related to the continental break-up and plate drift that led to the formation of the southern Atlantic Ocean in the Early Cretaceous. Strike analysis and distortion decomposition show that most of the data are two-dimensional (2D) but sensitive to distant off-profile structures. Data fit an ENE regional geoelectric strike direction, consistent with the geological and tectonic setup. A joint 2D inversion of the TE and TM modes defined by this strike direction was undertaken and the obtained model exhibits signatures of the different tectonic events in the area. The model suggests that the SE Borborema province is electrically separated into two parts. The first, comprising the southern domain of the province (Sergipano belt and Pernambuco-Alagoas block), has a highly heterogeneous crust and an anomalously conductive upper mantle. The second, comprising the transversal domain of the province (Alto Moxotó terrain), displays crust and upper mantle predominantly homogeneous and resistive. A deep Neoproterozoic lithospheric shear zone (Pernambuco lineament) marks the limit between the two contrasting domains. Also, the region where the Jatobá basin is located in the southern domain presents a striking conductor at upper- to mid-crustal depths beneath the basin. These results correlate well with seismic refraction data that indicate thicker crust for the transversal domain than for the southern domain, with the thinnest crust coinciding with the location of the Jatobá basin. The data support the conclusion that the lithosphere of the southern domain of the Borborema province was significantly stretched in the Cretaceous during the opening of the South Atlantic Ocean, allowing refertilization of depleted upper mantle with incompatible elements from enriched deeper mantle material and reactivation of older crustal fabrics. The conductivity increase below the Jatobá basin is associated with ionic conduction in a currently reactivated fracture zone filled with high salinity fluid. Apparently, the Alto Moxotó terrain worked as a region of higher resistance to stretching, causing the crustal thinning and geoelectric effects to be concentrated to the south of the Pernambuco lineament.

Espectroscopia multi-objeto e imageamento de Abell 586 com GMOS - o estado dinâmico de um aglomerado de galáxias com arcos gravitacionais  

NASA Astrophysics Data System (ADS)

Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

Ground-based astronomical instrument for planetary protection  

NASA Astrophysics Data System (ADS)

Planetary protection consists of the measurement and characterization of near-earth objects including earth threatening asteroids and earth orbiting debris. The Lockheed Martin STAR Labs in Palo Alto California is developing new astronomical instruments for use in planetary protection. The observation of asteroids is standard for astronomical facilities and there are available instruments designed with this specific science mission in mind. Orbital debris observation and characterization has a somewhat different set of requirements and includes large fields of view with simultaneous spectro-polarimetric data on multiple closely spaced objects. Orbital debris is comprised of spent rocket bodies, rocket fairing covers, paint chips, various satellite components, debris from satellite collisions and explosions and nonoperational satellites. The debris is present in all orbital planes from Low Earth orbit out to the geosynchronous graveyard orbit. We concentrate our effort on the geosynchronous and nearby orbits. This is because typical groundbased astronomical telescopes are built to track at sidereal rates and not at the 1 degree per second rates that are required to track low earth orbiting objects. The orbital debris materials include aluminum, mylar, solar cell materials, composite matrix material and other materials that are used in the fabrication of satellites and launch vehicles. These materials typically have spectral features in different wavebands than asteroids which are mostly composed of materials with molecular absorption bands such as in H2O. This will drive an orbital debris material identification instrument to wavebands and resolutions that are typically not used in asteroid observations.

Case series of 226 ?-hydroxybutyrate-associated deaths: lethal toxicity and trauma.  

PubMed

?-Hydroxybutyrate (GHB) and its prodrugs are drugs of abuse that were also sold as "dietary supplements." Users present to emergency departments with overdose, impaired driving, withdrawal, and associated trauma. We compiled a series of GHB-associated deaths to elucidate lethal risks, GHB concentrations, cointoxicants, products, uses, and medical interventions. Death records were reviewed for toxicology, autopsy findings, and history. Inclusion cutoffs were as follows: 5/10 mg/L of GHB (antemortem blood/urine) and 50/20/7 mg/L of GHB (postmortem blood/urine/vitreous). Of 226 deaths included, 213 had cardiorespiratory arrest and 13 had fatal accidents. Seventy-eight deaths (35%) had no cointoxicants. Sixteen deaths involved "supplements" and 1 involved pharmaceutical GHB (Xyrem, Jazz Pharmaceuticals, Palo Alto, CA). Postmortem blood GHB was 18 to 4400 mg/L (median, 347 mg/L) in deaths negative for cointoxicants. Cardiorespiratory arrest occurred prehospital in 100% of 184 cases with available history. Of 72 cases with antemortem adverse effects reported, medical assistance was delayed or absent in 66; of these, acute GHB ingestion was known in 51, including 40 left to "sleep off" adverse effects. Thirty others were left "sleeping" and found dead. ?-Hydroxybutyrate is lethal even without cointoxicants, directly and through fatal accidents. Medical interventions were frequently delayed or absent despite known GHB ingestion, and witnessed adverse events and cardiorespiratory arrest occurred prehospital. Education is needed about the lethality of GHB and the necessity for prompt medical intervention. PMID:20825811

Investigation of active regions at high resolution by balloon flights of the Solar Optical Universal Polarimeter (SOUP)  

NASA Technical Reports Server (NTRS)

SOUP is a versatile, visible-light solar observatory, built for space or balloon flight. It is designed to study magnetic and velocity fields in the solar atmosphere with high spatial resolution and temporal uniformity, which cannot be achieved from the surface of the earth. The SOUP investigation is carried out by the Lockheed Palo Alto Research Laboratory, under contract to NASA's Marshall Space Flight Center. Co-investigators include staff members at a dozen observatories and universities in the U.S. and Europe. The primary objectives of the SOUP experiment are: to measure vector magnetic and velocity fields in the solar atmosphere with much better spatial resolution than can be achieved from the ground; to study the physical processes that store magnetic energy in active regions and the conditions that trigger its release; and to understand how magnetic flux emerges, evolves, combines, and disappears on spatial scales of 400 to 100,000 km. SOUP is designed to study intensity, magnetic, and velocity fields in the photosphere and low chromosphere with 0.5 arcsec resolution, free of atmospheric disturbances. The instrument includes: a 30 cm Cassegrain telescope; an active mirror for image stabilization; broadband film and TV cameras; a birefringent filter, tunable over 5100 to 6600 A with 0.05 A bandpass; a 35 mm film camera and a digital CCD camera behind the filter; and a high-speed digital image processor.

Measurement of the time-dependent distribution of ionization states in an argon plasma from a Mach-10 jet  

NASA Astrophysics Data System (ADS)

Results from experiments designed to measure the time-dependent distribution of ionization states in an argon plasma produced by laser irradiation of a high-Mach-number gas jet are presented. The gas valve/nozzle target system was designed for nominal Mach-10 performance and produced a jet of neutral gas several centimeters long from a nozzle exit of 1.5 mm diameter. The jet was irradiated at a position having an approximate atomic density of 1 x 10(18)/cu cm by 500 J of 351-nm laser light with a pulse width of 600 ps at the NLUF's OMEGA laser facility. It was necessary to pre-ionize the gas in order to couple-in sufficient laser energy to produce a plasma. An argon plasma was then created that was dominated by charge states of Ar VIII through Ar XI. Comparison with a theoretical model which solved the time-dependent rate equations indicates that a plasma temperature of approximately 70 eV was achieved. A subsequent development effort carried out at the Lockheed Palo Alto Research Laboratory (LPARL) to improve the gas jet target system is also described. This work indicated that by increasing the pressure in the valve by a factor of 5 increased the coupling to the laser and produced significantly larger signals and higher plasma temperatures.
