Mina Ratones environmental restoration project included petrological, structural,geophysical, hydrogeological and hydrogeochemical studies. The main objective of the geologic-structural and geophysical studies was the Albala granite structural characterization around the Mina Ratones uranium mine. The location of facies, fault zones (faults and dykes) as well as the distribution of some physical properties inside the rock massif was obtained for a granitic black of 900, 500, and 500 m. The geologic-structural and geophysical techniques applied to Mina Ratones provided a multidisciplinary approach for high resolution characterization of rock massif, and the structures potentially containing fluids,able to be applied to the hydrogeological modelling to a particular area. Geological studies included a detailed structural mapping of the area surrounding the mine (1:5,000 scale), the geometric, kinematics, and dynamics analysis of fractures of all scales, the petrology and geochemistry of fault rocks and altered areas surrounding fractures, and the microstructural studies of samples from surface and core lags. The construction of geostatistical models in two and three dimensions had helped to characterize the Mina Ratones rock massif showing the spatial distribution of fault zones, fracture intensity, granite composition heterogeneities, fluid-rock interaction zones, and physical properties.

This geologic map covers four 7.5-minute quadrangles-The Wall, NM-CO (New Mexico-Colorado), Vermejo Park, NM-CO, Ash Mountain, NM, and Van Bremmer Park, NM. The study area straddles the boundary between the eastern flank of the Sangre de Cristo Mountains and the western margin of the Raton Basin, with about two-thirds of the map area in the basin. The Raton Basin is a foreland basin that formed immediately eastward of the Sangre de Cristo Mountains during their initial uplift, in the Late Cretaceous through early Eocene Laramide orogeny. Subsequently, these mountains have been extensively modified during formation of the Rio Grande rift, from late Oligocene to present. The map area is within that part of the Sangre de Cristo Mountains that is called the Culebra Range. Additionally, the map covers small parts of the Devil's Park graben and the Valle Vidal half-graben, in the northwestern and southwestern parts of the map area, respectively. These two grabens are small intermontaine basins, that are satellitic to the main local basin of the Rio Grande rift, the San Luis Basin, that are an outlying, early- formed part of the rift, and that separate the Culebra Range from the Taos Range, to the southwest.
Geophysical investigation of the Raton Basin

This thesis correlates gravity, magnetic, and seismic data for the Raton Basin of Colorado and New Mexico. The gravity data suggest that the study area, and the region around it, is in isostatic equilibrium. The free air anomaly in the southern portion of the study area suggests lack of local compensation due to Quaternary volocanic rock. The volcanic rock thickness, calculated from the free air gravity data, is 180 m. The gravity data indicated a crustal thickness of about 45 km, and the crust thinned from west to east. A basement relief map was constructed from the Bouquer gravity data. Computer techniques were developed to calculate the depth to the basement surface and to plot a contour map of that surface. The Raton Basin magnetic map defined the same surface found on the basement relief map since the overlying sedimentary rocks have no magnetism; therefore, any magnetism present is caused by the basement rock. A seismic survey near capulin Mountain detected a high level of microseismicity that may be caused by adjustment along faults or dormant volcanic activity.

Otros ratones se colocaron en grupos de 4 en cajas más pequenas y sin ninguno de estos objetos. Despues de estar 60 dias en estas condiciones se estúdio el comportamiento explorador de los ratones y su capacidad de aprendizaje de un laberinto complejo. Se observó una diferencia significativa entre los dos grupos de ratones ,tanto en su comportamiento explorador como en el tiempo empleado en resolver el laberinto y el número de ratones que lo resolvian en cada una de 10 pruebas sucesivas.
Geothermal Gradient impact on Induced Seismicity in Raton Basin, Colorado and New Mexico

Science.gov (United States)

Pfeiffer, K.; Ge, S.

2017-12-01

Since 1999, Raton Basin, located in southeastern Colorado and northern New Mexico, is the site of wastewater injection for disposing a byproduct of coal bed methane production. During 1999-2016, 29 wastewater injection wells were active in Raton Basin. Induced seismicity began in 2001 and the largest recorded earthquake, an M5.3, occurred in August 2011. Although most injection occurs in the Dakota Formation, the majority of the seismicity has been located in the crystalline basement. Previous studies involving Raton Basin focused on high injection rates and high volume wells to determine their effect on increased pore pressure. However, the geothermal gradient has yet to be studied as a potential catalyst of seismicity. Enhanced Geothermal Systems throughout the world have experienced similar seismicity problems due to water injection. Raton's geothermal gradient, which averages 49± 12°C/km, is much higher then other areas experiencing seismicity. Thermal differences between the hot subsurface and cooler wastewater injection have the potential to affect the strength of the rock and allow for failure. Therefore, we hypothesis that wells in high geothermal gradient areas will produce more frequent earthquakes due to thermal contrast from relatively cold wastewater injection. We model the geothermal gradient in the surrounding areas of the injection sites in Raton Basin to assess potential spatial relationship between high geothermal gradient and earthquakes. Preliminary results show that the fluid pressure increase from injecting cool water is above the threshold of 0.1MPa, which has been shown to induce earthquakes. In addition, temperatures in the subsurface could decrease up to 2°C at approximately 80 m from the injection well, with a temperature effect reaching up to 100 m away from the injection well.

1980-12-01

Using National Uranium Resource Evaluation criteria, the Raton Quadrangle (New Mexico and Colorado) contains one environment favorable for uranium deposits, the permeable arkosic sandstone members of the Pennsylvanian-Permian Sangre de Cristo Formation for either peneconcordant or roll-type deposits. The favorable parts of the Sangre de Cristo lie mostly in the subsurface in the Raton and Las Vegas Basins in the eastern part of the quadrangle. An area in the Costilla Peak Massif was investigated for uranium by determining geochemical anomalies in stream sediments and spring waters. Further work will be required to determine plutonic environment type. Environments unfavorable for uranium deposits include the Ogallala, Raton, and Vermejo Formations, the Trinidad Sandstone, the Pierre Shale, the Colorado Group, the Dakota Sandstone, the Morrison Formation, the Entrada and Glorieta Sandstones, Mississippian and Pennsylvanian rocks, quartz-pebble conglomerates, pegmatities, and Tertiary granitic stocks
Aerial gamma ray and magnetic survey: Raton Basin Project. The Raton and Santa Fe Quadrangles of New Mexico. Final report

1979-11-01

In 1978, EG and G geoMetrics collected 4955 line miles of high sensitivity airborne radiometric and magnetic data in New Mexico within the Raton and Santa Fe quadrangles. These quadrangles represent part of the Raton Basin Project. All radiometric and magnetic data for the two quadrangles were fully reduced and interpreted by geoMetrics, and are presented as three volumes; one Volume I covering both quadrangles and separate Volume II's for the individual quadrangles. Over 50% of the survey area is covered by flat lying Mesozoic and Cenozoic deposits of the southern Great Plains Province. The western and southern portions of the area contain a combination of Precambrian and Paleozoic igneous and metamorphic rocks. These rocks occur primarily within and in close proximity to the Sangre de Cristo Mountains and late Cenozoic volcanic deposits occur to the west of the mountains and in the Las Vegas Volcanic region. Uranium deposits are scattered throughout the region, but none are known to be economic at the time of this report
Raton basin assessment of coalbed methane resources. [USA - Colorado and New Mexico

Coalbed methane resources of the Raton basin were assessed through an analysis of public and proprietary sources encompassing stratigraphic, structural, hydrologic, coal rank, and gas-content data. Mapping of coal seams within the Vermejo Formation and Raton Formation revealed several net-coal thickness maxima of 80 ft along the synclinal axis of the basin. However, this sizable coal resource is distributed among multiple, thin, laterally discontinuous coal seams; approximately 60 percent of the total coal in the Raton Formation and 50 percent in the Vermejo Formation occur in seams thinner than 4 ft. Coal rank of the basal Vermejo Formation ranges from high-volatile C to low-volatile bituminous, indicating adequate thermal maturity for methane-generation. Coal seam gas contents show considerable scatter, ranging from 4 to 810 CF/T (ash free), and vary more closely with depth below the hydrologic potentiometric surface than with depth below ground level. Exclusive of shallow and intruded coal seams, in-place coalbed methane resources are estimated at 8.4 to 12.1 TCF, with a mean average of 10.2 TCF. The apparent highest concentration of coalbed methane (24 BCF/mi[sup 2]) occurs along the La Veta trough in Colorado in an area that is geologically less well studied. A second maximum of 8 BCF/mi[sup 2] occurs southeast of Vermejo Park in New Mexico. Successful coalbed methane development in the Raton basin will require favourable coal seam geometry, depth, and reservoir properties in addition to sufficient in-place resources. Local fracturing and enhanced permeability may occur along folds, such as the Vermejo anticline, that splay off the Sangre de Cristo thrust belt. 16 refs., 9 figs.

In June 2011, the Track Fire burned 113 square kilometers in Colfax County, northeastern New Mexico, and Las Animas County, southeastern Colorado, including the upper watersheds of Chicorica and Raton Creeks. The burned landscape is now at risk of damage from postwildfire erosion, such as that caused by debris flows and flash floods. This report presents a preliminary hazard assessment of the debris-flow potential from basins burned by the Track Fire. A pair of empirical hazard-assessment models developed using data from recently burned basins throughout the intermountain western United States were used to estimate the probability of debris-flow occurrence and volume of debris flows at the outlets of selected drainage basins within the burned area. The models incorporate measures of burn severity, topography, soils, and storm rainfall to estimate the probability and volume of post-fire debris flows following the fire. In response to a design storm of 38 millimeters of rain in 30 minutes (10-year recurrence-interval), the probability of debris flow estimated for basins burned by the Track fire ranged between 2 and 97 percent, with probabilities greater than 80 percent identified for the majority of the tributary basins to Raton Creek in Railroad Canyon; six basins that flow into Lake Maloya, including the Segerstrom Creek and Swachheim Creek basins; two tributary basins to Sugarite Canyon, and an unnamed basin on the eastern flank of the burned area. Estimated debris-flow volumes ranged from 30 cubic meters to greater than 100,000 cubic meters. The largest volumes (greater than 100,000 cubic meters) were estimated for Segerstrom Creek and Swachheim Creek basins, which drain into Lake Maloya. The Combined Relative Debris-Flow Hazard Ranking identifies the Segerstrom Creek and Swachheim Creek basins as having the highest probability of producing the largest debris flows. This finding indicates the greatest post-fire debris-flow impacts may be expected to Lake Maloya

Mechanical Engineering is a professional engineering discipline which involves the application of principles of physics, design, manufacturing and maintenance of mechanical systems. It requires a solid understanding of the key concepts including mechanics, kinematics, thermodynamics and energy. Mechanical engineers use these principles and others in the design and analysis of automobiles, aircrafts, heating and cooling systems, industrial equipment and machinery. In addition to these main areas, specialized fields are necessary to prepare future engineers for their positions in industry, such as mechatronics and robotics, transportation and logistics, fuel technology, automotive engineering, biomechanics, vibration, optics and others. Accordingly, the Springer Handbook of Mechanical Engineering devotes its contents to all areas of interest for the practicing engineer as well as for the student at various levels and educational institutions. Authors from all over the world have contributed with their expertise and support the globally working engineer in finding a solution for today's mechanical engineering problems. Each subject is discussed in detail and supported by numerous figures and tables. DIN standards are retained throughout and ISO equivalents are given where possible. The text offers a concise but detailed and authoritative treatment of the topics with full references. (orig.)

Full Text Available Lack of basic sanitation is linked to population growth disjointed of public policies. This work developed between July 2015 and July 2016 aimed to evaluate the perceptions of riverside land owners on the status of water bodies in the locations of Ratones River and Peri Lagoon, Florianópolis (Santa Catarina. We interviewed 51 residents in total. And the residents of Ratones knew a larger number of rivers and described direct supply of water bodies to their homes, compared to that obtained in the community of Peri Lagoon, where most homes was supplied by the public network. Both communities have shown intradomiciliary water filtration, assumed riparian forests degraded, considered the rainwater important for ecosystems health, and reported lack of sewage treatment. We conclude that residents tended to have an anthropocentric environmental vision, which residents interpret the environment as a space disconnected from the man.

Full Text Available Introducción. Encephalitozoon intestinalis es un microsporidio parásito del intestino, que puede diseminarse en pacientes inmunocomprometidos. Existen referencias de modelos animales inmunosuprimidos para el estudio de la microsporidiosis utilizando fármacos que producen supresión total de la respuesta inmune; sin embargo, no se han estudiado los efectos de inmunosupresores con acción selectiva sobre los componentes de esta respuesta. Objetivo. Evaluar el efecto de la inmunosupresión con ciclosporina A (CsA en ratones C57BL/6 infectados con E. intestinalis. Materiales y métodos. Se utilizaron 80 ratones C57BL/6 distribuidos en cuatro grupos: infectados, inmunosuprimidos e infectados, inmunosuprimidos no infectados y controles. La inmunosupresión con CsA (50 mg/kg se realizó vía intraperitoneal durante todo el estudio. En la semanas 2, 3, 4 y 6 posteriores a la infección se obtuvo sangre para determinar los anticuerpos, y materia fecal para evaluar la cinética de excreción de esporas. Además, se extrajeron varios órganos para estudiar la histopatología y observar la posible diseminación del parásito. Resultados. La producción de anticuerpos IgG fue mayor en los ratones inmunocompetentes infectados que en los inmunosuprimidos infectados con E. intestinalis. No se encontró el parásito en órganos diferentes al intestino delgado en los dos grupos infectados. Sin embargo, la excreción de esporas, tanto en heces como en líquido duodenal, fue mayor en el grupo inmunosuprimido infectado. Conclusión. La CsA en el modelo en ratón no indujo la diseminación de E. intestinalis ni la exacerbación de la enfermedad, pero contribuyó al aumento en la cinética de excreción de esporas y la disminución de la producción de anticuerpos IgG en los ratones inmunosuprimidos infectados.

Fossilized coenobia of the alga Scenedesmus (Chlorococcales) were recovered in palynomorph assemblages from a lower Paleocene mudstone in the Upper Cretaceous and Paleocene Raton Formation of Colorado and New Mexico. This is the first description of fossil Scenedesmus from Tertiary rocks. Two species, Scenedesmus tschudyi sp. nov. and Scenedesmus hanleyi sp. nov., are present in the assemblages. Coenobia of S. tschudyi sp. nov. are characterized by lunate terminal cells and fusiform median cells. As in species of modern Scenedesmus, coenobia of S. tschudyi sp. nov. occur with four or eight cells. Coenobia of S. hanleyi sp. nov. have four oval cells and are smaller than coenobia of S. tschudyi sp. nov. Fossil coenobia of Scenedesmus co-occur with the fossil alga Pediastrum in Raton Formation mudstones. Because these genera co-occur in modern lakes and ponds, the co-occurrence of fossil Scenedesmus and Pediastrum in ancient nonmarine rocks is interpreted to indicate deposition of sediment in freshwater lakes and ponds. ?? 1989.

Extracts of neem (Azadirachta indica A. Juss.) and Gliricidia sepium Jacquin, locally known as 'mata-raton', are used to control pests of maize. Their application, however, is known to affect soil microorganisms. We investigated if these extracts affected emissions of methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O), important greenhouse gases, and dynamics of soil inorganic N. Soil was treated with extracts of neem, mata-raton or lambda-cyhalothrin, used as chemical control. The soil was amended with or without urea and incubated at 40% and 100% water holding capacity (WHC). Concentrations of ammonium (NH4+), nitrite (NO2(-)) and nitrate (NO3(-)) and emissions of CH4, CO2 and N2O were monitored for 7d. Treating urea-amended soil with extracts of neem, mata-raton or lambda-cyhalothrin reduced the emission of CO2 significantly compared to the untreated soil with the largest decrease found in the latter. Oxidation of CH4 was inhibited by extracts of neem in the unamended soil, and by neem, mata-raton and lambda-cyhalothrin in the urea-amended soil compared to the untreated soil. Neem, mata-raton and lambda-cyhalothrin reduced the N2O emission from the unamended soil incubated at 40%WHC compared to the untreated soil. Extracts of neem, mata-raton and lambda-cyhalothrin had no significant effect on dynamics of NH4(+), NO2(-) and NO(3)(-). It was found that emission of CO2 and oxidation of CH4 was inhibited in the urea-amended soil treated with extracts of neem, mata-raton and lambda-cyhalothrin, but ammonification, N2O emission and nitrification were not affected.

Full Text Available AIM: The present study aimed on testing the efficiency of four sampling methods for identification and quantification applied in studies on the biodiversity and spatial-temporal distribution of the phycoperiphyton in the Ratones River estuary; METHODS: The sampling were carried out in three sampling stations along the Ratones River in March and August 2008. The methodologies used for the separation of the periphyton from the sediment were made with the use of sieves and trapping tissue. A removing method through manual agitation and "in situ" analysis was used for epiphytes. To evaluate the efficiency of the methodology for periphyton, data on phytoplankton was included for comparative reasons; RESULTS: The trapping method option was the most appropriate for removing the live specimens from the sediment, and to try to minimize the problems found with the other two methodologies tested. In the case of the epiphytic microalgae the best counting technique resulted from the "in situ" method; CONCLUSIONS: In summary, the results presented here support the difficulties faced in studying phycoperiphytic samples in estuaries, which are shallow and dynamic environments, and for that reason the communities occurring in these areas are constantly influenced by the sediment.OBJETIVO: O presente trabalho tem por objetivo testar a eficiência de quatro métodos de coleta para a identificação e quantificação empregadas no estudo sobre a biodiversidade e distribuição espaço temporal do ficoperifíton no estuário do rio Ratones; MÉTODOS: As coletas foram realizadas em três estações de amostragem ao longo do rio Ratones em março e agosto de 2008. As metodologias testadas para separação do perifíton do sedimento foram realizadas através do uso de peneiras e armadilhas de tecido. Para as epífitas, foi utilizado método de remoção através de agitação manual e análise "in situ". Para avaliar a eficiência da metodologia para perifíton, foram

Higley, Debra K.

2007-01-01

Introduction The purpose of the U.S. Geological Survey's (USGS) National Oil and Gas Assessment is to develop geologically based hypotheses regarding the potential for additions to oil and gas reserves in priority areas of the United States. The USGS recently completed an assessment of undiscovered oil and gas resources of the Raton Basin-Sierra Grande Uplift Province of southeastern Colorado and northeastern New Mexico (USGS Province 41). The Cretaceous Vermejo Formation and Cretaceous-Tertiary Raton Formation have production and undiscovered resources of coalbed methane. Other formations in the province exhibit potential for gas resources and limited production. This assessment is based on geologic principles and uses the total petroleum system concept. The geologic elements of a total petroleum system include hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). The USGS used this geologic framework to define two total petroleum systems and five assessment units. All five assessment units were quantitatively assessed for undiscovered gas resources. Oil resources were not assessed because of the limited potential due to levels of thermal maturity of petroleum source rocks.

The structural complexity of coral reefs is important for their function as shelter and feeding habitats for coral reef fishes, but physical disturbance by human activities often reduce complexity of the reefs by selectively destroying fragile and more complex coral species. The damselfish Springer......'s demoiselle Chrysiptera springeri primarily utilize complex coral heads for shelter and are hence vulnerable to human disturbance. In order to evaluate the potential effect of habitat degradation on juvenile fish growth, coral reef cover, fish age at settling and otolith growth, juvenile Springer's demoiselle...... was investigated on a protected and non-protected coral reef in Darvel Bay, Borneo. The protected reef had higher coverage of complex branching corals and exhibited a more complex 3-dimensional structure than the non-protected reef. Springer's demoiselle settled at the same age on non-protected and protected reefs...

Inclusion criteria comprised of English springer spaniel dogs with tachypnea and hyperthermia that subsequently developed weakness or collapse, with or without signs of hemorrhage, soon after a period of mild-to-moderate exercise. The pedigrees of the four affected dogs, as well as eleven related English springer spaniels, were then analyzed to determine a presumptive mode of genetic inheritance.Results: Four dogs met the inclusion criteria. All four were male, suggesting the possibility of a recessive sex-linked heritable disorder. Pedigree analysis suggests that more dogs may be potentially affected, although these dogs may have never had the concurrent triggering drug/activity/event to precipitate the clinical syndrome. There was complete resolution of clinical signs in three of the four dogs with aggressive symptomatic and supportive therapy, with one dog dying during treatment.Conclusion: Dogs with canine stress syndrome have the potential for rapid recovery if treated aggressively and the complications of the disease (eg, coagulopathy are anticipated. All four dogs were male, suggesting the possibility of a recessive sex-linked mode of inheritance. Further genetic analyses should be strongly considered by those

Users obviously expect library collections to be shaped to meet their information needs. Today, online systems have replaced the good old "Book Suggestion Register" to help readers provide libraries with input. Moreover, e-books lend themselves by their nature to a trial period, whereby the needs and the potential usage of collections can be effectively measured. In this sense, the trial of Springer e-books on engineering done in October-November last year was extremely fruitful because it showed the interest of the community and provided us with essential feedback. Following that trial, the Library now provides access to a collection of Springer e-books on Engineering published in 2012 and 2013 and also on Mathematics (2010-2013). These collections complement the Springer Physics and Astronomy and "Lecture Notes in Physics" e-books series. As usual, your feedback is most welcome! Please contact us by e-mail.

Is there temporal variation on solid waste stranding in mangroves? A case study in Ratones mangrove, Florianopolis, Brazil

Full Text Available Mangrove areas are decreasing around the world due to population increase. The most damaging activities include embankments, shrimp farming, and dumping of wastes. The temporal and spatial stranding patterns of solid waste are important to establish probable sources and understand their role in the dispersion of organisms through natural areas. In this study, we analyze temporal variation of solid waste stranding in Ratones mangrove, northwestern of Santa Catarina Island (Brazil. Samplings were carried out monthly during one year in four different areas. In each area, two 50 m2 random plots were sampled per month. All solid waste strands on the plots were removed, quantified, and qualified. Plastic and nylon items (both made of petroleum represented 80% of waste stranding. There were significant differences in temporal stranding with regard to plastic, but not to nylon. Wastes were found in all samples throughout the year, and some areas are more affected than others. Places with dense edges of Spartina alterniflora Loisel (Poaceae seem to have less solid waste inside mangrove forest, perhaps due to the effect of grass acting as a mesh barrier. The results reflected concerns with conservation, considering that these coastal ecosystems are impacted by waste dumping throughout the year, with highest concentration within important nursery points.

Springer-Verlag history of a scientific publishing house

CERN Document Server

Sarkowski, Heinz

1996-01-01

This book describes the fortunes and activities of one of the few specialist publishing houses still in the hands of the same family that established it over 150 years ago and with it gives a portrayal of those members who directed it. In doing so it covers a period of momentous historical events that directly and indirectly shaped the firm's actions and achievements. But this volume tells not only, in word and picture, the story of Springer-Verlag but also, interwoven with it, the story of publishing in Germany over the span of a hundred years. The text, densely packed with carefully researched facts and figures, is illuminated and supplemented by many illustrations whose captions, together with the author's notes, contain a wealth of important and interesting information. A second volume contains the history of the publishing house from 1945 to 1992.
Dasymetric high resolution population distribution estimates for improved decision making, with a case study of sea-level rise vulnerability in Boca Raton, Florida

Science.gov (United States)

Ziegler, Hannes Moritz

Planners and managers often rely on coarse population distribution data from the census for addressing various social, economic, and environmental problems. In the analysis of physical vulnerabilities to sea-level rise, census units such as blocks or block groups are coarse relative to the required decision-making application. This study explores the benefits offered from integrating image classification and dasymetric mapping at the household level to provide detailed small area population estimates at the scale of residential buildings. In a case study of Boca Raton, FL, a sea-level rise inundation grid based on mapping methods by NOAA is overlaid on the highly detailed population distribution data to identify vulnerable residences and estimate population displacement. The enhanced spatial detail offered through this method has the potential to better guide targeted strategies for future development, mitigation, and adaptation efforts.
Petrological mineralogical and geochemical characterization of the granitoids and fracture fillings developed in Ratones Mines (Spain)

2002-01-01

The petrological, mineralogical and geochemical characterisation of the granitoids and fracture fillings developed in the Ratones Mine (Caceres, Spain) has been done in order to understand rock-water interaction processes which control water geochemical parameters. Special interest has been devoted to the analysis and interpretation of REE patterns in the solid phase (granitoids and fracture fillings) because they constitute geochemical tracers in water-rock interaction process. Moreover, REE are considered as actinide analogues. In order to characterise the solid phase (granitoids and fracture fillings) several investigation scales (system, outcrop, whole rock, mineral and geochemical components) have been considered and different types of samples have been analysed. These factors control the methodological approach used in this investigation. The analytical methods we have used in this investigation are microscope, qualitative and semi-quantitative methods (XRD, SEM,EDAX) and quantitative methods (ICP-MS, XRF, EM, LAM-IC-MS). The bulk of the granitoids located around the Ratones Mine Belongs to the alkaline feldspar granite-sienogranite lihotype and they show a peraluminous and subalkaline pattern. From the mineralogical point of view, they are composed by quartz, K-feldspar (Or>90%), showing sericitation, moscovitization and turmolinization altherations, alkaline plagioclase (An-=-3%), usually altered to sericite, saussirite and less frequently affected by moscovitization processes, Fe-Al biotite, frequently affected by chloritization processes and sometimes replaced by muscovite, and finally muscovite (>2% celadonite and <4% paragonite) both of primary and secondary origin. The differences observed between the different lithotypes are related with the modal proportion of the principal minerals,with the presence or absence of certain accessory minerals ( turmaline, cordierite), with specific textural patterns, grain size and also with the richness in specific

Uranium hydrogeochemical and stream sediment reconnaissance of the Raton NTMS quadrangle, New Mexico

International Nuclear Information System (INIS)

Morgan, T.L.; Broxton, D.E.

1978-10-01

A total of 824 water and 1340 sediment samples were collected from 1844 sample locations in the Raton NTMS quadrangle and analyzed for uranium. Samples were collected at a nominal density of one per 10 km 2 . Notably high uranium values were found in both water and sediment samples collected from tributaries of Costilla Creek in the Culebra Range. Uranium contents in stream waters from this area range from individual high values of 145.1 and 76.1 to values slightly higher than the background concentrations in adjacent areas. Stream sediments range from 4.1 to 202.2 ppM uranium and average 30 ppM. The Culebra Range is a favorable setting for hard-rock type uranium mineralization. The uraniferous water and sediment samples call attention to this area as a possible exploration target. Numerous groups of ground waters with high uranium concentrations come from locations along the Cimarron and Sierra Grande Arches in the eastern part of the quadrangle. The Cimarron Arch is the locus of the largest group of uraniferous ground waters, with concentrations ranging between 5.2 and 103.3 ppB. Aquifers from which these samples were derived include the Fort Hays and Smoky Hill members of the Niobrara formation, the Pierre shale, and Quaternary surficial deposits. Most of the uraniferous ground waters along the Sierra Grande Arch occur in small, isolated groups that probably represent minor, local sources of uranium. Carbonate complexing of uranium may contribute to the high uranium values seen in these samples. Stream sediment samples with high uranium concentrations (10.1 to 51.4 ppM) were found in several drainages from the western front of the Taos Range. One group of locations providing high-uranium sediments is near known uranium occurrence in the vicinity of Cabresto and Latir Peaks. The western Taos Range is a favorable setting for hard rock uranium mineralization and may also warrant further study

Filtrations on Springer fiber cohomology and Kostka polynomials

Science.gov (United States)

Bellamy, Gwyn; Schedler, Travis

2018-03-01

We prove a conjecture which expresses the bigraded Poisson-de Rham homology of the nilpotent cone of a semisimple Lie algebra in terms of the generalized (one-variable) Kostka polynomials, via a formula suggested by Lusztig. This allows us to construct a canonical family of filtrations on the flag variety cohomology, and hence on irreducible representations of the Weyl group, whose Hilbert series are given by the generalized Kostka polynomials. We deduce consequences for the cohomology of all Springer fibers. In particular, this computes the grading on the zeroth Poisson homology of all classical finite W-algebras, as well as the filtration on the zeroth Hochschild homology of all quantum finite W-algebras, and we generalize to all homology degrees. As a consequence, we deduce a conjecture of Proudfoot on symplectic duality, relating in type A the Poisson homology of Slodowy slices to the intersection cohomology of nilpotent orbit closures. In the last section, we give an analogue of our main theorem in the setting of mirabolic D-modules.

Primary seborrhoea in English springer spaniels: a retrospective study of 14 cases.

Science.gov (United States)

Scott, D W; Miller, W H

1996-04-01

Primary seborrhoea was diagnosed in 14 English springer spaniels over a 17-year period. Seven of the dogs developed clinical signs by two years of age. The dermatosis began as a generalised non-pruritic dry scaling which gradually worsened. Some dogs remained in this dry (seborrhoea sicca) stage, but in most cases the dermatosis became greasy and inflamed (seborrhoea oleosa and seborrhoeic dermatitis). Eight of the dogs suffered from recurrent episodes of superficial or deep bacterial pyoderma. Histological findings in skin biopsy specimens included marked orthokeratotic hyperkeratosis of surface and infundibular epithelium, papillomatosis, parakeratotic capping of the papillae, and superficial perivascular dermatitis in which lymphocytes and mast cells were prominent. The dogs with seborrhoea sicca responded more satisfactorily to therapy with topical emollient-humectant agents or oral omega-3/omega-6 fatty acid supplementation. Dogs with seborrhoea oleosa and seborrhoeic dermatitis did not respond satisfactorily to topical therapy. One dog, however, responded well to etretinate and omega-3/omega-6 fatty acid administration. No dog was cured.

A los ratones, entre 20-22 g de peso y 6 semanas de nacidos, se les administró esta solución CM-95 tratada magnéticamente por vía intraperitoneal en un esquema de dos inoculaciones; luego se administró por la misma vía el 5_fluorouracilo a una dosis de 150 mg/m2 de superficie corporal de cada ratón. Se evaluó el conteo total y diferencial de leucocitos antes de inocular el 5-fluorouracilo, y a los tres y siete días de aplicado este. La celularidad de médula ósea y bazo y la observación microscópica del corte histológico de hígado y bazo por la técnica de inclusión en parafina y tinción con eosina hematoxilina al 10% se evaluaron a los siete días de haber aplicado el 5- fluorouracilo. La solución CM-95, tratada magnéticamente, logró modular los efectos del 5-fluorouracilo con una actividad protectora rehabiltadora, para los parámetros evaluados en médula ósea, sangre periférica, bazo e hígado. Estos resultados abren nuevas perspectivas para la aplicación del sistema acuoso tratado magnéticamente como inmunomodulador.

Con el fin de establecer su control por vacunación el Instituto Finlay ha desarrollado una vacuna a partir del polisacárido capsular Vi. Para su estudio experimental no existe un modelo animal que reproduzca los síntomas y la patogenia de la enfermedad. El desarrollo de modelos experimentales y los estudios histopatológicos aportan informaciones al conocimiento de la enfermedad y a la interpretación de los procesos inmunológicos. Nos propusimos caracterizar el cuadro histopatológico en los ratones utilizados en las pruebas de potencia de la vacuna antitifoídica basada en polisacárido Vi purificado y su comparación con la vacuna de células enteras. Se utilizaron 240 ratones de ambos sexos pertenecientes a la línea C57BL/6 procedentes del Centro Nacional para la Producción de Animales de Laboratorio (CENPALAB, con un peso comprendido entre 18 y 22 g. Se evaluó la protección comparativa entre las vías intraperitoneal y subcutánea utilizando dos inmunógenos, a partir del polisacárido Vi y con la variante de células enteras. Se logró una considerable eficacia en ratón C57BL/6 para reproducir las lesiones compatibles con Salmonella typhi en hígado y bazo. La sobrevivencia del grupo no vacunado fue de un 15%. La sobrevivencia de los ratones correspondientes al grupo vacunado con polisacárido Vi osciló entre 90% y 100% para ambas vías, mientras que los vacunados con células enteras variaron entre 50% y 100% para la vía subcutánea y entre 60% y 100% para la vía intraperitoneal todo lo cual evidencia la superioridad de la vacuna a partir del polisacárido capsular Vi sobre la variante de células enteras en la especie ratón C57BL/6

Adicionalmente, se empleó un bacteriófago de origen comercial. La fagoterapia fue evaluada mediante profilaxis y terapia de infecciones localizadas y sistémicas causadas por la inoculación de MRSA por vía subcutánea y endovenosa respectivamente. Se probó la efectividad de tres esquemas terapéuticos: monoterapia, cóctel de fagos en múltiples dosis y de cóctel de fagos en una sola dosis. También se comparó la actividad terapéutica de los fagos frente a vancomicina y clindamicina. Resultados. El cóctel de fagos y la terapia a diversas dosis fueron efectivos para prevenir y controlar infecciones localizadas por MRSA, su actividad fue similar a la de vancomicina y clindamicina. La dosis única del cóctel de fagos no logró controlar la infección localizada; asimismo, la fagoterapia no resultó efectiva en infecciones sistémicas. Conclusiones. La fagoterapia se proyecta como una alternativa viable frente a infecciones causadas por MRSA. Se requieren estudios que evalúen aspectos relacionados con la inocuidad de los fagos frente al paciente

Cuando los mosquitos se alimentaron sobre hamster con altas viremias (7.5, 6.5 y 6.3 dex en 0.1 ml. de suero, los porcentajes de infección de los mosquitos y los de transmisión fueron altos. Sin embargo, cuando los mosquitos se alimentaron sobre Proechimys hendei con viremias bajas (1,4 y 2.6 dex en 0.1 ml. de suero el porcentaje de infección de los mosquitos fue muy bajo y no hubo transmisión. Cuando la viremia en el Proechimys fue de 4.4 dex en 0.1 ml. de suero, el porcentaje de infección de los mosquitos aumentó y hubo transmisión baja (9%. Los resultados sugieren que Psorophora confinnis es un mosquito que tiene un alto umbral de infección para EEV subgrupo ID.

Full Text Available Se estudió la biodistribución y la farmacocinética de taninos condensados purificados y marcados radioisotópicamente, extraídos a partir de la corteza de las especies forestales Pinus caribaea Morelet var caribaea y Casuarina equisetifolia previa administración por vía oral y endovenosa, con el empleo de ratones como biomodelo. Los taninos estudiados, con una alta capacidad antioxidante y diferenciados por la propiedad de formar complejos con proteínas, presentaron una rápida biodistribución hacia los diferentes órganos y tejidos, con manifestaciones de un importante acúmulo en el estómago e intestinos. Los taninos de ambas especies describen una biodistribución que se ajusta a un modelo bicompartimental de distribución. Se reportan los parámetros farmacocinéticos como tiempo de residencia medio, aclaramiento total, área bajo la curva, biodisponibilidad e instante de tiempo en que ocurre la máxima incorporación a partir de las curvas del aclaramiento sanguíneo.Biodistribution and pharmacokinetics of radioisotope-labeled and purified condensed tannins from Pinus caribaea Morelet var caribaea and Casuarina equisetifolia barks were studied after they were orally and intravenously administered to mice which served as biomodels. The studied tannins, known as strong antioxidants and protein complex ligands, showed a rapid biodistribution into several organs and tissues. Accumulation of these substances in the stomach and intestines was significant. Tannins from both species described a biodistribution that adapted to a biocompartimental model of distribution. Pharmacokinetic parameters such as mean residence time, total clearance, area under the curve, bioavailability and the moment when the maximum incorporation occurs were estimated from the blood clearance curves.

The Carboniferous Los Ratones pluton is composed by two main facies: equigranular and porphyric. The uranium mineralization hosted by the metamorphic rock on the NW border of the pluton is related to a fluor- rich greisen related to the equigranular facies. The detailed mapping of the pluton host rock and the uranium mineralization shows a well-defined structural control on both the granite emplacement, particularly on the porphyric facies, and on the migration of the mineralized fluids. Four sets of fractures participate on this control. The two main with N and NE trends coincide clearly with the west and northwest border of the pluton as well as with the high-grade uranium manifestations. The third and fourth ones respectively corresponds to E-W and NW striking fractures, which are less developed in relation to the main fractures considering their frequency and size. Fractures of the four sets are high dipping close to vertical, attitude corroborated by geophysical studies in the area where the NE fractures are the best developed. In addition to the mentioned features, granite-related acidic and basic dikes follow mainly these orientations. The fracture sets seem to be related to a high-east dipping meridian fault system with right horizontal main movement component and subordinate normal displacement. These faults partially reactivated heterogeneities of the metamorphic rocks, mainly the dominant foliation. Changes on the strike of these fractures formed dilatant zones where magmatism and related mineralization were concentrated. (authors) [es

Full Text Available Una vez estudiada la toxicidad de la vacuna VA-DIFTET® (vacuna antidiftérica antitetánica por administración a dosis única en dos especies de animales, se impone la evaluación a dosis repetida, teniendo en cuenta que el esquema de inmunización en humanos prevé la aplicación de tres dosis cuando el componente pertusis de la DPT está contraindicado. Se emplearon 210 ratones OF-1 de ambos sexos. Los grupos experimentales fueron similares a los de la prueba a dosis única con la vacuna dúplex, anatoxina diftérica, anatoxina tetánica, adyuvante, tiomersal, solución salina fisiológica y un grupo control no tratado. Un grupo de hembras y otro de machos fue asignado aleatoriamente a cada tratamiento y para recibir 1, 2 ó 3 dosis por vía intramuscular. Tras cada aplicación se evaluó la aparición de síntomas clínicos, el incremento de peso, el consumo de agua y alimento y la dinámica de la respuesta inmune contra las anatoxinas tetánica y diftérica, específicamente de tipo IgG, mediante ELISA indirecto. Al término de las observaciones los animales fueron sacrificados y se realizaron estudios anatomopatológicos. Además, durante el sacrificio se evaluó el índice relativo de bazo y timo, así como la relación bazo/timo. No se comprobaron alteraciones que evidenciaran toxicidad por parte de la vacuna y sus componentes. Asimismo, se demostró una marcada respuesta inmune en los grupos vacunales e inoculados con las anatoxinas. Se considera que los resultados de la prueba fueron satisfactorios.

Full Text Available Introducción: el extracto oleoso de la semilla de Carapa guianensis Aublet ha tenido diversos usos biomédicos. Recientemente fue evaluado este extracto, el cual manifestó grandes potencialidades como antioxidante en ensayos in vivo; pero poco se conoce de su efecto sobre el ADN en biomodelos experimentales. Objetivo: evaluar el potencial genotóxico del extracto oleoso de la semilla de Carapa guianensis en el ensayo de aberraciones cromosómicas de células de la médula ósea de ratones Balb/c. Métodos: se formaron cinco grupos experimentales: un grupo placebo (Tween 65 al 2 %, tres tratados con niveles de dosis del extracto (400, 1 000 y 2 000 mg/kg, administrados por vía oral durante 14 días; por último, un grupo control positivo tratado con ciclofosfamida, en dosis de 50 mg/kg por vía intraperitoneal 48 y 24 h antes de la eutanasia. Se administraron cinco animales/sexo/grupo. Después de los 14 días de administración se les efectuó la eutanasia por dislocación cervical y se les extrajo la médula ósea del fémur para proceder a realizar la técnica citogenética de aberraciones cromosómicas. Resultados: los resultados entre controles y tratados con el extracto no difirieron para los dos sexos en las variables índice mitótico, Gaps, células con poliploidías, número de células con aberraciones cromosómicas y cromatídicas y el porcentaje de células con aberraciones. Sin embargo, sí difirieron controles y tratados contra el grupo tratado con ciclofosfamida, lo que valida nuestros resultados. Conclusiones: el extracto oleoso de la semilla de la Carapa guianensis no posee potencialidades genotóxicas en la formación de aberraciones cromosómicas, sobre todo estructurales en células de la médula ósea de ratones Balb/c de ambos sexos.

Sacrificamos los animales en el pico de la parasitemia (12º día y fijamos las glándulas sublinguales en ALFAC. Los cortes histológicos teñidos con HE fueron evaluados histométricamente (cariometría y estereología. La parasitemia fue más elevada en las hembras. Histopatológicamente, los "ácinos" (acini de los animales infectados eran menores, con escasa secreción, y conductos estriados menores. Los núcleos de las "medialunas" eran menores y había nidos de amastigotes en el citoplasma. Cariométricamente, los núcleos de los ácinos, medialunas y conductos estriados eran menores en los ratones infectados. Estereológicamente, los volúmenes relativos ocupados por ácinos y conductos estriados fueron menores e, inversamente, fue mayor el volumen para el tejido conjuntivo de los machos infectados. Las densidades de superficie de ácinos y conductos fueron mayores, y el diámetro y el espesor de la pared menores, en este grupo. Por otro lado, la densidad de ácinos fue menor, y las de los conductos estriados y tejido conjuntivo, fueron mayores en las hembras infectadas. Las densidades de superficie de ácinos y conductos estriados fueron mayores, mientras que el diámetro y espesor de la pared de los ácinos fueron menores (y las de los conductos estriados mayores, en este grupo.

El D-004, extracto lipídico de los frutos de la palma real (Roystonea regia que consiste en una mezcla de ácidos grasos, ha mostrado poseer una moderada acción antidepresiva. El objetivo de este trabajo consistió en comparar los efectos del tratamiento oral con D-004, con los AGw3 y con su terapia combinada en el modelo del nado forzado en ratones. Para ello, ratones machos se distribuyeron en 8 grupos: uno control tratado con el vehículo, dos con D-004 (250 y 500 mg/kg , dos con AGw3 (250 y 500 mg/kg, dos con la combinación y uno con imipramina (10 mg/kg i.p.. Todos los tratamientos disminuyeron significativamente el tiempo de inmovilidad con respecto al control, sin diferencias entre dosis similares de los respectivos tratamientos. En conclusión, el D-004, los AGw3 y su terapia combinada resultaron igualmente efectivos en reducir el tiempo de inmovilidad de los ratones, sin manifestarse efectos aditivos o sinérgicos con la administración conjunta de ambas sustancias.Depression is among the major causes of morbidity and mortality of adult population and its pharmacologic management includes among other alternative options, the use of the complementary medicine, e.g. the fish oil rich in Omega-3 fatty acids (AGw3.

Full Text Available Busulfán es un agente alquilante bifuncional tipo-éster, que interfiere con la replicación del ADN. Dosis elevadas de este compuesto son aplicadas antes de los transplantes de médula ósea y de células germinales, sin embargo no han sido cuantificados el daño ni la recuperación del sistema reproductor. Para cuantificar la recuperación del efecto en la espermatogénesis, se usaron ratones de la cepa Balb C, a los que se les inyectó Busulfán intraperitonealmente, 40 mg/kg de peso corporal, y se evaluó el peso testicular y la concentración espermática en cola de epidídimo, a los 30, 54 y 72 días y se realizaron cortes histológicos de testículo. Los resultados fueron analizados con la prueba U Mann-Whitney p>0.05. A los 30 días el peso testicular, la concentración espermática y el diámetro de los túbulos seminíferos presentaron una drástica reducción del 77,8%, 97,9% y 34,3% respectivamente, comparados con el grupo control. A los 54 días, el peso testicular y el diámetro testicular muestran una recuperación del 70%. A los 72 días, la recuperación es completa en los parámetros evaluados. Por lo tanto, Busulfán aplicado en una sola dosis afecta significativamente la espermatogénesis en el ratón y se logra la recuperación completa en dos ciclos espermáticos.

En el presente trabajo se comparó la antigenicidad de dos mimotopos del virus de la hepatitis A en dos formatos diferentes: como péptidos lineales y como sistemas de péptidos de múltiples antígenos. Se emplearon sueros de ratones que fueron inmunizados con un sistema de péptidos de múltiples antígenos (tetramérico que contenían las secuencias peptídicas correspondientes a los dos mimotopos. Los mimotopos 46 y 56, tanto como péptidos lineales o en forma de sistema de péptidos de múltiples antígenos, fueron útiles para evaluar la respuesta de anticuerpos en el tiempo. El formato de sistema de péptidos de múltiples antígenos permitió una mayor sensibilidad en la detección de los anticuerpos inducidos por el inmunógeno. Estos resultados son de importancia en estudios de inmunogenicidad para una posterior aplicación de los antígenos evaluados en un ensayo tipo ELISA.

Walfrido Moraes Tomás

2008-12-01

Full Text Available This is the first report on the distribution and relative abundance of the broad-snouted caiman on Santa Catarina Island. The study estimated the relative abundance of caiman along the rivers at Estação Ecológica de Carijós, in addition to evaluating the occurrence of this species in the entire area of the Ratones River plain on the northwestern portion of the island. The mean relative abundance obtained by nocturnal counts was 0.25 (±0.07 caiman/km surveyed. There was a weak correlation between the number of caimans and the air temperature. Based on interviews with the local community and nocturnal surveys of caimans in rivers and reservoirs surrounding the protected area, we concluded that the range occupied by caimans covered the entire area of the Ratones river plain, inhabiting natural habitats (rivers, mangroves, swamps as well as artificial habitats (reservoirs and water channels. Although this study provides basic information about the broad-snouted caiman population on this part of the island, it is aimed mainly at providing guidance for future research.

2004-03-01

Full Text Available Algunas manifestaciones clínicas de la rabia, así como los resultados de experimentos con cultivos celulares y animales de laboratorio han llevado a sugerir que el virus de la rabia afecta la neurotransmisión gabaérgica. En la corteza cerebral existen diferentes tipos de neuronas que sintetizan el neurotransmisor GABA. Éstas se pueden identificar con marcadores neuronales, entre los que se destacan tres proteínas ligadoras de calcio: la parvoalbúmina (PV, la calbindina (CB y la calretinina (CR. El virus de la rabia se disemina a través de la corteza cerebral pero se desconocen sus posibles efectos citopáticos sobre las neuronas gabaérgicas. Para evaluar el efecto de la rabia sobre estas neuronas, se estudió mediante inmunohistoquímica la expresión de PV, CB y CR en la corteza frontal de ratones normales y ratones infectados con virus 'calle' o virus 'fijo' de la rabia. La PV se expresó en neuronas multipolares dispersas regularmente entre las capas II y VI, y en botones sinápticos que bordeaban el soma de las neuronas piramidales. La inmunorreactividad a CB se manifestó en dos franjas corticales: la primera, en las capas supragranulares II y III en neuronas con somas redondeados e inmersos en un neuropilo intensamente marcado; la segunda, en las capas infragranulares V y VI en neuronas multipolares dispersas y rodeadas por un neuropilo menos reactivo. La CR se expresó en neuronas bipolares con somas fusiformes distribuidas en las seis capas corticales, pero concentradas principalmente en las capas II y III. Hubo una característica común en las muestras infectadas con los dos tipos de virus: la inmunotinción a PV fue más intensa que en las muestras normales. La infección derivada del virus 'calle' no causó alteraciones adicionales en la expresión de las tres proteínas. En contraste, la infección con virus 'fijo' produjo una reducción notable del número de neuronas CB+, así como de la inmunorreactividad a CB en el

Full Text Available Introducción: El ensayo de micronúcleos transplacentario, ha sido desarrollado con el objetivo de evaluar el potencial genotóxico en la descendencia y demostrar la capacidad de un agente de causar daños cromosómicos durante el período prenatal. Éste realiza el registro de aberraciones cromosómicas, demostrando si una sustancia determinada puede ser clastogénica o aneugénica en el feto, a través de la exposición materna. Objetivo: Por lo cual en el presente trabajo se tuvo como objetivo determinar la frecuencia espontánea e inducida de micronúcleos transplacentarios en ratones de la línea Balb/c. Pretendiendo vincular de esta forma el efecto genotóxico y reproductivo de una droga a evaluar por esta metodología. Materiales y métodos: Se formaron 4 grupos experimentales, el primero un control negativo (simulacro, el segundo control solvente NaCl (0,9%, en el tercero se utilizo la ciclofosfamida en dosis de 50 mg/kg, y el cuarto se utilizó la bleomicina en dosis de 20 mg/kg. Todos los grupos se administraron por vía intraperitoneal los días 14, 15 y 16 de la gestación y 24 h después de la última inoculación se procedió al sacrificio de las gestantes por dislocación cervical. Obteniéndose las muestras de médula ósea materna e hígado fetal. Resultados: Se obtuvo como resultado los valores espontáneos e inducidos de los índices de citotoxicidad y de genotoxicidad, así como el total de micronúcleos divididos según niveles de daños.Discusión y conclusiones: Se observo mayor inducción de daño en células hepáticas fetales que en médula ósea materna.

Full Text Available Salmonella enterica serovar Typhi es un microorganismo que provoca más de 16 millones de casos de fiebre tifoidea con aproximadamente 600 000 muertes al año en todo el mundo. Dentro de las vacunas antitifoídicas la de polisacárido capsular Vi ha encontrado, gracias a sus incuestionables ventajas, una gran aceptación entre productores y consumidores. El presente trabajo aborda el estudio de inmunogenicidad de la vacuna antitifoídica cubana de polisacárido Vi vax-TyViâ en ratones. El estudio estuvo conformado por un grupo control no inoculado y un segundo grupo que recibió 0,05 mL de la vacuna por vía intramuscular. Se tomaron muestras de sangre a los -3, 7, 14, 21, 28, 42, 56 y 84 días. La actividad de anticuerpos IgG antipolisacárido Vi de los sueros individuales fue determinada por ELISA. Los datos fueron analizados por grupo y por sexo y se calculó el porcentaje de seroconversión, considerándose respondedor aquel animal que al menos aumentara en cuatro veces su título inicial. La respuesta de anticuerpos inducida por la vacuna mostró un aumento notable de los títulos de IgG antipolisacárido Vi en el grupo vacunado (100% de seroconversión, mientras que el grupo control no incrementó sus niveles mínimos iniciales (0% de respondedores. Aunque más dispersa, la respuesta de anticuerpos antiVi fue significativamente mayor en las hembras que en los machos.

The availability of diverse sources of data related to health and illness from various types of modern communication technology presents the possibility of augmenting medical knowledge, clinical care, and the patient experience. New forms of data collection and analysis will undoubtedly transform epidemiology, public health, and clinical practice, but what ethical considerations come in to play? With a view to analysing the ethical and regulatory dimensions of burgeoning forms of biomedical big data, Brent Daniel Mittelstadt and Luciano Floridi have brought together thirty scholars in an edited volume that forms part of Springer's Law, Governance and Technology book series in a collection titled The Ethics of Biomedical Big Data. With eighteen chapters partitioned into six carefully devised sections, this volume engages with core theoretical, ethical, and regulatory challenges posed by biomedical big data.
Greisen deposits associated to carboniferous post-orogenic granites with mineralization potential, Sierra de Fiambala, Catamarca, Argentina

2008-01-01

The Fiambala range is located in the central south part of the province of Catamarca, Western Sierras Pampeanas, Argentina. It is largely conformed by Precambrian metamorphic rocks, a Cambrian granitic intrusive, Ordovician basic and ultra basic rocks and epi zonal Carboniferous granites (Los Ratones, El Salto and Ayacucho Granites). The Carboniferous granites are sub alkaline, weakly peraluminous, high silica (except for the porphyritic facies of Los Ratones granite) and moderately enriched in K. Contents of trace elements and REE indicate that El S alto and Ayacucho granites and the granular facies of Los Ratones granite have characteristics of evolved and differentiated granite associated with hydrothermal systems. The variations of trace elements, particularly Sn, W, U, Rb, Ba, Zr and Sr suggest that they correspond to granites with mineralization potential. Genetically linked to these granites there are Sn, W, U and minor base metals greisen deposits. The hydrothermal process that yield to these deposits involved two main alteration stages, beginning with alkali metasomatism follow by greissenization. According to the isotopic ages the hydrothermal processes postdate about 1 Ma the magmatic activity. The analyses of the granites and the associated greisen deposits confirm that the post orogenic carboniferous magmatism is the major metallogenetic control of the ore deposits from the studied area. This metallogenetic control could be a useful tool in prospecting similar deposits in the rest of the Western Sierras Pampeanas. (Author)
Approach for delineation of contributing areas and zones of transport to selected public-supply wells using a regional ground-water flow model, Palm Beach County, Florida

Rapid urban development and population growth in Palm Beach County, Florida, have been accompanied with the need for additional freshwater withdrawals from the surficial aquifer system. To maintain water quality, County officials protect capture areas and determine zones of transport of municipal supply wells. A multistep process was used to help automate the delineation of wellhead protection areas. A modular ground-water flow model (MODFLOW) Telescopic Mesh Refinement program (MODTMR) was used to construct an embedded flow model and combined with particle tracking to delineate zones of transport to supply wells; model output was coupled with a geographic information system. An embedded flow MODFLOW model was constructed using input and output file data from a preexisting three-dimensional, calibrated model of the surficial aquifer system. Three graphical user interfaces for use with the geographic information software, ArcView, were developed to enhance the telescopic mesh refinement process. These interfaces include AvMODTMR for use with MODTMR; AvHDRD to build MODFLOW river and drain input files from dynamically segmented linear (canals) data sets; and AvWELL Refiner, an interface designed to examine and convert well coverage spatial data layers to a MODFLOW Well package input file. MODPATH (the U.S. Geological Survey particle-tracking postprocessing program) and MODTOOLS (the set of U.S. Geological Survey computer programs to translate MODFLOW and MODPATH output to a geographic information system) were used to map zones of transport. A steady-state, five-layer model of the Boca Raton area was created using the telescopic mesh refinement process and calibrated to average conditions during January 1989 to June 1990. A sensitivity analysis of various model parameters indicates that the model is most sensitive to changes in recharge rates, hydraulic conductivity for layer 1, and leakance for layers 3 and 4 (Biscayne aquifer).

The goal of this study was to investigate land use changes in urban and peri-urban Hyderabad and their influence on wastewater irrigated rice using Landsat ETM + data and spectral matching techniques. The main source of irrigation water is the Musi River, which collects a large volume of wastewater and stormwater while running through the city. From 1989 to 2002, the wastewater irrigated area along the Musi River increased from 5,213 to 8,939 ha with concurrent expansion of the city boundaries from 22,690 to 42,813 ha and also decreased barren lands and range lands from 86,899 to 66,616 ha. Opportunistic shifts in land use, especially related to wastewater irrigated agriculture, were seen as a response to the demand for fresh vegetables and easy access to markets, exploited mainly by migrant populations. While wastewater irrigated agriculture contributes to income security of marginal groups, it also supplements the food basket of many city dwellers. Landsat ETM + data and advanced methods such as spectral matching techniques are ideal for quantifying urban expansion and associated land use changes, and are useful for urban planners and decision makers alike. ?? 2011 Springer Science+Business Media B.V.

El D-004 es un extracto lipídico extraído a partir del fruto de la palma real (Roystonea regia, inhibe la 5 a-reductasa y previene la hiperplasia prostática benigna, y muestra un efecto antidepresivo moderado en el ensayo de nado forzado y suspensión por la cola. Objetivo: comparar el efecto del D-004 con la imipramina y la sertralina sobre la duración de las conductas de inmovilidad, nado y escalado en el ensayo de nado forzado. Métodos: se distribuyeron los ratones en ocho grupos: control (vehículo, tres tratados con D-004 (100, 250 y 500 mg/kg, dos con sertralina y dos con imipramina (30 y 50 mg/kg respectivamente. Estos se colocaron en un cilindro de cristal que contenía agua a una altura de 6 cm y se cuantificaron las conductas. Resultados: la administración oral de D-004 (100, 250 y 500 mg/kg durante 14 días redujo significativamente el tiempo de inmovilidad con respecto al grupo control (17, 22 y 25 % y aumentó significativamente la conducta de nado en 1,58, 1,68 y 1,74 veces. Este efecto resulta moderado (25 % comparado con las reducciones alcanzadas por la sertralina y la imipramina (³ 60 %. Las dosis mayores (250 y 500 mg/kg ocasionaron incrementos de la conducta de escalado, 2,79 y 3,55 veces superiores a la del grupo control, lo que mostró semejanza con la imipramina, aunque con una menor eficacia. Conclusiones: el D-004 ejerce un moderado efecto antidepresivo, lo que pudiera contribuir al manejo de los pacientes con hiperplasia prostática benigna en los cuales se informa coincidencia de cuadros depresivos.

Analyzed phenotypic, structural and ultrastructural alterations induced by Cd{sup +2} in hepatocytes extracted from Swiss Albino mice. Cadmium was given orally in watery solution of CdCl{sub 2} during 100 days at concentrations of 50 ppm, 100 ppm and 150 ppm. In controls, distilled water alone was used. The samples were processed with the paraffin inclusion and hematoxylin-eosin coloration techniques for light microscopy. The conventional technique was used for transmission electron microscopy . Phenotypic (size and weight differences) and physiologic changes (muscular weakness, unrest) were found; at the structural level it was noticed loss of trabecular disposition and of lobular architecture, lymphocyte agglomeration, vacuolisation, dilatation of sinusoid and central vein, among others. The ultrastructural study evidenced alterations coincident with those seen with light microscopy, which were accentuated with the increase of metal concentration: nucleolus with a high number of fibrillar centers (50 ppm); voluminous lipidic drops in the cytoplasm, loose endoplasmic rough reticulum, cytoplasmic vacuolisation, altered lysosomes and peroxisomes (100 ppm); contracted nucleis with condensed chromatin, dilatation of intracellular space and mitochondria, and loss of fibrillar areas (150 ppm). Cadmium produces a toxic effect in the hepatic cells; the effect is more severe at higher concentration, leading to cellular necrosis.

The intervention with the hydrolysate led to the restoration of the count of total leukocytes at values similar to those of the control group and to an increase in the levels of lymphocytes in peripheral blood. It also stimulated the proliferation of the cells from the mononuclear phagocytic system and the metabolism of the macrophages, expressed by a higher activity of the lysosomal acid phsosphatase and the rise of the relative weight and the hematopoietic activity of the spleen.

Mustelus schmitti is an endangered endemic shark of the southwest Atlantic, and an important economical resource in Argentina, Brazil and Uruguay. The objective of this study was to describe the trophic ecology of M. schmitti in Anegada Bay, its feeding strategy and diet composition, along with the possible dietary shifts, due to season, sex, ontogeny and the different geographical features of the bay. Our results show that M. schmitti is a carnivorous opportunistic predator, feeding on a variety of benthic invertebrates. The diet presented seasonal and ontogenetic variations, while no differences in diet composition were observed between sexes or the different sampling sites. This species behave as a generalize feeder, with a wide trophic spectrum and a diverse diet.

Full Text Available Los ratones BALB/c inmunizados SC con promastigotes no viables de Leishmania mexicana pifanoi, desarrollaron respuestas de hipersensibilidad tardia (RHT contra el parásito. En contraposición, los ratones BALB/c infectados crónicamente con L.m. pifanoi y aquellos inmunizados IV con una dosis supraóptima de parásitos muertos, mostraron inhibición de la RHT. La supresión de la RHT en los animales infectados, estuvo precedida por un estado transitorio de inmunidad celular, manifestado durante la fase inicial del desarrollo de las lesiones (4-12 semanas. La inhibición de la RHT observada en los animales infectados o inmunizados con dosis supraóptimas, fue causada por un mecanismo activo, transferible a receptores singénicos a través de las células esplénicas de los donantes suprimidos. La población de células supresoras fue no adherente a "nylon", sensible al tratamiento con un suero anti-timocitos de ratón y C', y de acción específica sobre la RHT contra antígenos leishmánicos. Se propone que la ocurrencia de células T supresoras de la RHT en los animales infectados crónicamente o inmunizados con dosis supraóptimas, es causada por el exceso de carga antigénica. Esta última, en el caso de los animales infectados, secundaria a una falla primaria en el control inmunológico de la población parasitaria.A T suppressor cell population that specifically shut down delayed hypersensitivity responses (DHR to the parasite was found in both BALB/c mice chronically infected with Leishmania mexicana pifanoi and in naive mice which had received a single IV supraoptimal dose of killed parasites. At the early phase of infection mice exhibited a transitory state of cell-mediated immunity against the parasite that was abrogated when lesions reached their accelerated phase of growth. Results suggest that in both infected and high-dose immunized mice, the activation of T suppressor cells of DHR is related to antigen overload.

Transitions between the outpatient and inpatient sector are a critical phase in medication treatment. This article provides an overview of published problem areas and examples of best practice in the intersectoral medication treatment. Data with regard to related problem areas and examples of best practice was collected in August 2011 by a systematic literature research. The relevant literature was identified using the following databases and search engines: MEDLINE, The Cochrane Library, EMBASE, Google, and Google Scholar. Additionally, a hand search was done on the websites of SpringerLink and Thieme Connect. The initial search yielded a total of 4,409 records which were further selected in two screening steps and analysed according to their relevance. Of the remaining 63 records, 3 exclusively described problem areas, 11 of them examples of best practice, and 49 provided information on both problem areas and examples of best practice with regard to intersectoral medication treatment. Among other things, problem areas include varying legal regulations in inpatient and outpatient medication treatment, drug therapy interruptions after hospital discharge, or deficits in communication and continuity of care. Examples of best practice are projects, programmes, initiatives, recommendations, and points to consider with respect to medication reconciliation, pharmaceutical support, or transitions of care. Problem areas as well as examples of best practice are mainly focused on the transition from inpatient to outpatient care. Copyright © 2013. Published by Elsevier GmbH.

This map covers the Big Costilla Peak, New Mex.&nash;Colo. quadrangle and adjacent parts of three other 7.5 minute quadrangles: Amalia, New Mex.–Colo., Latir Peak, New Mex., and Comanche Point, New Mex. The study area is in the southwesternmost part of that segment of the Sangre de Cristo Mountains known as the Culebra Range; the Taos Range segment lies to the southwest of Costilla Creek and its tributary, Comanche Creek. The map area extends over all but the northernmost part of the Big Costilla horst, a late Cenozoic uplift of Proterozoic (1.7-Ga and less than 1.4-Ga) rocks that is largely surrounded by down-faulted middle to late Cenozoic (about 40 Ma to about 1 Ma) rocks exposed at significantly lower elevations. This horst is bounded on the northwest side by the San Pedro horst and Culebra graben, on the northeast and east sides by the Devils Park graben, and on the southwest side by the (about 30 Ma to about 25 Ma) Latir volcanic field. The area of this volcanic field, at the north end of the Taos Range, has undergone significantly greater extension than the area to the north of Costilla Creek. The horsts and grabens discussed above are all peripheral structures on the eastern flank of the San Luis basin, which is the axial part of the (about 26 Ma to present) Rio Grande rift at the latitude of the map. The Raton Basin lies to the east of the Culebra segment of the Sangre de Cristo Mountains. This foreland basin formed during, and is related to, the original uplift of the Sangre de Cristo Mountains which was driven by tectonic contraction of the Laramide (about 70 Ma to about 40 Ma) orogeny. Renewed uplift and structural modification of these mountains has occurred during formation of the Rio Grande rift. Surficial deposits in the study area include alluvial, mass-movement, and glacial deposits of middle Pleistocene to Holocene age.

In a previous laboratory experiment, extracts of neem (Azadirachta indica A. Juss.) and Gliricidia sepium Jacquin, locally known as mata-raton, used to control pests on crops, inhibited emissions of CO 2 from a urea-amended soil, but not nitrification and N 2 O emissions. We investigated if these extracts when applied to beans (Phaseolus vulgaris L.) affected their development, soil characteristics and emissions of carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) in a greenhouse environment. Untreated beans and beans planted with lambda-cyhalothrin, a commercial insecticide, served as controls. After 117 days, shoots of plants cultivated in soil amended with urea or treated with lambda-cyhalothrin, or extracts of neem or G. sepium were significantly higher than when cultivated in the unamended soil, while the roots were significantly longer when plants were amended with urea or treated with leaf extracts of neem or G. sepium than when treated with lambda-cyhalothrin. The number of pods, fresh and dry pod weight and seed yield was significantly higher when bean plants were treated with leaf extracts of neem or G. sepium treatments than when left untreated and unfertilized. The number of seeds was similar for the different treatments. The number of nodules was lower in plants fertilized with urea, treated with leaf extracts of neem or G. sepium, or with lambda-cyhalothrin compared to the unfertilized plants. The concentrations of NH 4 + , NO 2 - and NO 3 - decreased significantly over time with the lowest concentrations generally found at harvest. Treatment had no significant effect on the concentrations of NH 4 + and NO 2 - , but the concentration of NO 3 - was significantly lower in the unfertilized soil compared to the other treatments. It was found that applying extracts of neem or G. sepium leaves to beans favored their development when compared to untreated plants, but had no significant effect on nitrification in soil.

We demonstrate the use of an expert-assisted spatial model to examine geographic factors influencing the poaching risk of a rare plant (American ginseng, Panax quinquefolius L.) in Shenandoah National Park, Virginia, USA. Following principles of the analytic hierarchy process (AHP), we identified a hierarchy of 11 geographic factors deemed important to poaching risk and requested law enforcement personnel of the National Park Service to rank those factors in a series of pair-wise comparisons. We used those comparisons to determine statistical weightings of each factor and combined them into a spatial model predicting poaching risk. We tested the model using 69 locations of previous poaching incidents recorded by law enforcement personnel. These locations occurred more frequently in areas predicted by the model to have a higher risk of poaching than random locations. The results of our study can be used to evaluate resource protection strategies and to target law enforcement activities. ?? Springer Science+Business Media, LLC (outside the USA) 2011.

SDS-PAGE. Se ensayó el síndrome giroxina en ratones, los que mostraron cambios en el comportamiento, confirmando que la enzima tipo trombina aislada es giroxina. Se evaluó la acción de esta enzima sobre los niveles de fibrinógeno plasmático en ratones, comparándola con la del veneno crudo. Se comprobó que la enzima provoca una disminución de los niveles plasmáticos de fibrinógeno hasta la incoagulabilidad, durante la primer hora de inoculación, mientras que el veneno entero produjo una reducción del nivel plasmático en un 60%; sin embargo, en ambos casos, se evidenció una rápida reposición de fibrinógeno plasmático, alcanzando sus valores normales en un plazo de 10 horas. Se observó coagulación intravascular con la administración de giroxina una hora después de la inoculación, evidenciados en estudios histológicos de tejido pulmonar, cardíaco y hepático. En ensayos realizados in vitro, la enzima aislada mostró capacidad de degradar fibrinógeno como así también coágulos de fibrina, mientras que el veneno exhibió débil actividad hidrolítica sobre ambos sustratos. Es probable que esta baja actividad sea debida a la baja concentración de la enzima en el veneno. La disminución de los niveles de fibrinógeno plasmático observado en ratones se debería a la acción coagulante de la enzima, sin embargo no se descarta que también contribuya a este proceso una acción hidrolítica sobre fibrinógeno y fibrina por parte de la enzima.

Introducción. El caseinato de sodio, una sal de la caseína utilizada como agente proinflamatorio en ratones, es capaz de inducir granulopoyesis en vivo e incrementar la producción de citocinas esenciales en dicho evento.Objetivo. Evaluar si el caseinato de sodio es capaz de inducir un efecto biológico en células de origen linfoide y la producción de citocinas involucradas con este linaje.Materiales y métodos: Se utilizaron ratones hembra BALB/c de 8 a 12 semanas de edad. Los animales se inyectaron cuatro veces, con intervalos de 48 horas, por vía intraperitoneal con 1 ml de caseinato de sodio (10 % de SFB p/v). La población de linfocitos B y la incorporación de bromodesoxiuridina (BrdU) se analizaron mediante citometría de flujo. La detección de la interleucina 7 se evaluó mediante la técnica de ELISA.Resultados. Tras la inyección por vía intraperitoneal, el número de linfocitos B 220+ provenientes del bazo de ratones tratados con caseinato de sodio aumentó comparados con los que solo recibieron el vehículo como tratamiento (89,01±1,03 Vs. 75,66±2,08), así como la incorporación de BrdU en células B220+ (38,59±4,48 Vs. 11,82±1,04). Se evidenció, asimismo, el incremento en la concentración de la interleucina 7 (IL-7) en el suero de los ratones tratados con caseinato de sodio, comparados con los que solo recibieron el vehículo (62,1±17,5 Vs. 26,9±4,4 pg/ml).Conclusión. El caseinato de sodio fue capaz de aumentar el número de linfocitos B en bazo de ratones, así como inducir la producción de IL-7, citocina clave para la linfopoyesis B.

Full Text Available The vaginal epithelial changes document reproductive cycles and provide an index of the functional status of the hypothalamic-pituitary-ovarian axis. However, it is necessary to understand the vaginal cytology relationship. In our work we study the vaginal epithelium of intact and ovariectomized female mice. We analyzed young, middle aged and aged vaginal cytology and compared them with an ovariectomized group. The results show that female young intact mice manifest a four days estrous cycle phases: estrous, metaestrous, diestrous and proestrous. In contrast, female middle aged and aged mice showed the persistence of diestrous phase. Ovariectomized mice showed a similar cytology than the middle aged and aged intact ones. In conclusion, the vaginal cytology evaluates the reproductive axis integrity and reflects the circulating sexual hormones levels action and/or modification, which could produce transient changes in behavior.Los cambios del epitelio vaginal documenta los ciclos reproductivos, el estado funcional del eje hipotálamo-hipófisis-ovario asociados con cambios en la conducta.

We produce a one‐year 2017 seismic‐hazard forecast for the central and eastern United States from induced and natural earthquakes that updates the 2016 one‐year forecast; this map is intended to provide information to the public and to facilitate the development of induced seismicity forecasting models, methods, and data. The 2017 hazard model applies the same methodology and input logic tree as the 2016 forecast, but with an updated earthquake catalog. We also evaluate the 2016 seismic‐hazard forecast to improve future assessments. The 2016 forecast indicated high seismic hazard (greater than 1% probability of potentially damaging ground shaking in one year) in five focus areas: Oklahoma–Kansas, the Raton basin (Colorado/New Mexico border), north Texas, north Arkansas, and the New Madrid Seismic Zone. During 2016, several damaging induced earthquakes occurred in Oklahoma within the highest hazard region of the 2016 forecast; all of the 21 moment magnitude (M) ≥4 and 3 M≥5 earthquakes occurred within the highest hazard area in the 2016 forecast. Outside the Oklahoma–Kansas focus area, two earthquakes with M≥4 occurred near Trinidad, Colorado (in the Raton basin focus area), but no earthquakes with M≥2.7 were observed in the north Texas or north Arkansas focus areas. Several observations of damaging ground‐shaking levels were also recorded in the highest hazard region of Oklahoma. The 2017 forecasted seismic rates are lower in regions of induced activity due to lower rates of earthquakes in 2016 compared with 2015, which may be related to decreased wastewater injection caused by regulatory actions or by a decrease in unconventional oil and gas production. Nevertheless, the 2017 forecasted hazard is still significantly elevated in Oklahoma compared to the hazard calculated from seismicity before 2009.

The Acquisition of Electronic Books in the Area of Astronomy in the UNAM

Science.gov (United States)

Juarez, B.

2015-04-01

The current high cost of electronic books coupled with the low budget for the astronomy libraries of the National Autonomous University of Mexico (UNAM) has led to the three libraries in the area of Astronomy to become part of the Group of Libraries in the area of sciences, which happened in 2011. This group was formed to support the purchasing of e-books: because of their high costs, it was impossible to acquire materials of interest for each library. As a result, a working group was formed to prepare lists of e-books to purchase in order to avoid duplication, acquire all needed titles, and combine resources. The goal was to purchase e-books from large publishing companies such as Springer and Elsevier, and also Cambridge UP, Oxford UP, World Scientific, Astronomical Society of the Pacific, and others. Through these joint purchases, the three campus Astronomy libraries — University City, Ensenada, and Morelia — have benefited from the acquisition of e-books from 2010 to 2013. This paper will present the ways the working group functioned, the policies that needed to be followed with regards to the selection and acquisition of e-books, and the benefits at both the Library and Group level.

Hydrostratigraphy and hydrogeology of the western part of Maira area, Khyber Pakhtunkhwa, Pakistan: A case study by using electrical resistivity

KAUST Repository

Farid, Asam M.

2012-06-27

Hydrostratigraphy and hydrogeology of the Maira vicinity is important for the characterization of aquifer system and developing numerical groundwater flow models to predict the future availability of the water resource. Conventionally, the aquifer parameters are obtained by the analysis of pumping tests data which provide limited spatial information and turn out to be costly and time consuming. Vertical electrical soundings and pump testing of boreholes were conducted to delineate the aquifer system at the western part of the Maira area, Khyber Pakhtun Khwa, Pakistan. Aquifer lithology in the eastern part of the study area is dominated by coarse sand and gravel whereas the western part is characterized by fine sand. An attempt has been made to estimate the hydraulic conductivity of the aquifer system by establishing a relationship between the pumping test results and vertical electrical soundings by using regression technique. The relationship is applied to the area along the resistivity profiles where boreholes are not drilled. Our findings show a good match between pumped hydraulic conductivity and estimated hydraulic conductivity. In case of sparse borehole data, regression technique is useful in estimating hydraulic properties for aquifers with varying lithology. © 2012 Springer Science+Business Media B.V.

Full Text Available Objetivo: comparar fetos de ratones Balb/c y ratas Sprague Dawley como biomodelos en el ensayo de micronúcleos transplacentarios, determinando la frecuencia espontánea e inducida, y vincular el efecto genotóxico y reproductivo. Métodos: se formaron tres grupos experimentales/especie: control negativo (simulacro, control solvente NaCl (0,9 % y ciclofosfamida 50 mg/kg. Todos los grupos se administraron por vía intraperitoneal los días 14, 15 y 16 de la gestación, y 24 h después de la última inoculación en ratones y 48 h en ratas se procedió a realizar la eutanasia de las gestantes, para obtener las muestras de hígado fetal. Resultados: los fetos de ratas Sprague Dawley demostraron tener menores índices de citotoxicidad y de genotoxicidad, y se obtuvieron los resultados más bajos de micronúcleos endógenos. Los mejores resultados de inducción de citotoxicidad y genotoxicidad por la alta formación de micronúcleos con ciclofosfamida fueron en fetos de ratas Sprague Dawley, los que resultaron más susceptibles al daño genotóxico de este mutágeno. Se corroboró el poder clastogénico transplacentario de la ciclofosfamida, vinculando este ensayo de genotoxicidad a toxicología de la reproducción. Conclusiones: los resultados sugieren el mejor uso de fetos de ratas Sprague Dawley como biomodelo en este ensayo cuando es utilizada la ciclofosfamida como control positivo por la vía y dosis estudiada; además, se pudieran utilizar en la evaluación de nuevas drogas con carácter antigenotóxico por vía transplacentaria.Objectives: to compare fetuses from Balb/c mice and Sprague Dawley rats as biomodels in transplacental micronuclei assay and to determine the spontaneous and induced frequency to link the genotoxic and reproductive effect.

Full Text Available La Fiebre Hemorrágica Argentina es una enfermedad producida por el virus Junín. Para la prevención de esta enfermedad se obtuvo una vacuna efectiva denominada Candid#1. Durante un ensayo clínico realizado en el INEVH, dos cepas de virus Junín fueron aisladas de sangre periférica de dos voluntarios mediante co-cultivo de células mononucleares. El objetivo de este trabajo fue comparar las características fenotípicas de atenuación de esas dos cepas recuperadas de humanos con las de la vacuna Candid#1 utilizando los indicadores de atenuación desarrollados por Contigiani y Sabattini en 1977. A tal fin se midieron los índices de letalidad, infección y protección en cobayos y ratones de diferentes edades. Las tres cepas investigadas resultaron letales para ratones recién nacidos pero no para ratones de 10 a 12 días, ratones adultos ni cobayos, aun a la más baja dilución inoculada. Los cobayos inoculados con las cepas recuperadas de humanos y con la cepa Candid#1 no presentaron síntomas de enfermedad y mostraron estar protegidos cuando fueron desafiados con una cepa patógena. Los índices de infección y de protección hallados indican que estas cepas poseen elevada capacidad infectante y protectora en las especies animales aquí estudiadas. Estos resultados demuestran que las cepas de virus Junín aisladas de voluntarios inmunizados con Candid#1 mantienen el mismo fenotipo atenuado de la vacuna Candid#1 después de un pasaje por humanos.

To evaluate the physiological response of Tillandsia capillaris Ruiz & Pav. f. capillaris, T. recurvata L., and T. tricholepis Baker to different air pollution sources, epiphyte samples were collected from a noncontaminated area in the province of Córdoba (Argentina) and transplanted to a control site as well as three areas categorized according to the presence of agricultural, urban, and industrial (metallurgical and metal-mechanical) emission sources. A foliar damage index (FDI) was calculated with the physiological parameters chlorophyll a, chlorophyll b, malondialdehyde (MDA), hydroperoxyconjugated dienes, sulfur (S) content, and dry weight-to-fresh weight ratio. In addition, electrical conductivity (E-cond), relative water content (RWC), dehydration kinetics (Kin-H(2)O), total phenols (T-phen), soluble proteins (S-prot), and activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase were determined. The parameters E-cond, FDI, SOD, RWC, and Kin-H(2)O can serve as suitable indicators of agricultural air pollution for T. tricholepis and T. capillaris, and CAT, Kin-H(2)O, and SOD can do the same for T. recurvata. In addition, MDA, T-phen, and S-prot proved to be appropriate indicators of urban pollution for T. recurvata. Moreover, FDI, E-cond, and SOD for T. recurvata and MDA for T. tricholepis, respectively, could be used to detect deleterious effects of industrial air pollution. © Springer Science+Business Media, LLC 2011

Full Text Available Population density and reproduction were studied in two leaf-eared mice (Phyllotis spp. in the Peruvian locality known as Lomas de Lachay. Density varied between 0-3 individuals ha-1 in P. andium, and between 0-12 individuals ha-1 in P. amicus. An annual cycle of population abundance was observed in both species. Phyllotis amicus showed no seasonal reproductive activity, but P. andium had seasonal reproduction with pregnant females principally observed between July and September. Differences in juvenile weight were related to litter size. It is likely that two young was the optimal litter size in the harsh and seasonal xeric environment of Lomas de Lachay. Our results suggest that P. amicus maintains low, highly dispersed populations in a harsh environment, and can reproduce at any time of the year, whereas P. andium appears to be a more irruptive species closely tied to rainfall patternsLa densidad poblacional y reproducción de dos ratones orejudos (Phyllotis spp. fueron estudiadas en la localidad peruana Lomas de Lachay. La densidad varió entre 0-3 individuos ha-1 en P. andium, y entre 0-12 individuos ha-1 en P. amicus. En ambas especies se observaron cambios poblacionales que sugieren la existencia de ciclos anuales en la abundancia poblacional. El patrón reproductivo en las dos especies de Phyllotis fue claramente distinto. Phyllotis amicus mostró una actividad reproductiva no estacional, mientras que P. andium tuvo una reproducción estacional observándose hembras preñadas principalmente entre julio y septiembre. La diferencia en el peso de los juveniles estuvo relacionada con el tamaño de la camada. Es probable que en las Lomas de Lachay el tamaño de camada óptimo sea de dos individuos. Nuestros resultados sugieren que P. amicus es una especie que mantiene poblaciones bajas, altamente dispersas en áreas desérticas, y que puede reproducirse durante todo el año; mientras que P. andium parece ser una especie que irrumpe más en

The normal morphological and functional values of orbits vary according to race, sex, and age. We measured the palpebral fissure using the marginal reflex distance (MRD 1 ), marginal limbal distance (MLD), and vertical height of the palpebral fissure (VHPF). Unfortunately, these measurements are all one-dimensional figures that measure the distance between two points; they have limitations when it comes to measuring the three-dimensional ocular surface. Therefore, this study used the area of corneal exposure (ACE), which shows a two-dimensional area, to measure changes between the sizes of eyes according to age. This study was conducted using preoperative photographs of Koreans in Daegu city, Korea, who underwent plastic surgery in our department except for eyelid surgery. We divided the subjects into eight groups, including ten males and ten females in each decade of age, from age 10 to over 80 years. A total of 160 people were recruited who were followed up for photograph analysis using Adobe Photoshop 7.0 software. In terms of the mean value, the ACEs were 73.3 ± 2% in male subjects and 77.1 ± 2% in female subjects, and values for female subjects were greater than those for male subjects (p Contents or the online Instructions to Authors www.springer.com/00266 .

Based on findings of limited studies during 1989-92, a reconnaissance investigation was conducted in 1993 to assess the effects of the Vermejo Irrigation Project on water quality in the area of the project, including the Maxwell National Wildlife Refuge. This project was part of a U.S. Department of the Interior National Irrigation Water-Quality Program to determine whether irrigation drainage has caused or has the potential to cause significant harmful effects on human health, fish, and wildlife and whether irrigation drainage may adversely affect the suitability of water for other beneficial uses. For this study, samples of water, sediment, and biota were collected from 16 sites in and around the Vermejo Irrigation Project prior to, during the latter part of, and after the 1993 irrigation season (April, August-September, and November, respectively). No inorganic constituents exceeded U.S. Environmental Protection Agency drinking-water standards. The State of New Mexico standard of 750 micrograms per liter for boron in irrigation water was exceeded at three sites (five samples), though none exceeded the livestock water standard of 5,000 micrograms per liter. Selenium concentrations exceeded the State of New Mexico chronic standard of 2 micrograms per liter for wildlife and fisheries water in at least eight samples from five sites. Bottom-sediment samples were collected and analyzed for trace elements and compared to concentrations of trace elements in soils of the Western United States. Concentrations of three trace elements at eight sites exceeded the upper values of the expected 95-percent ranges for Western U.S. soils. These included molybdenum at one site, selenium at seven sites, and uranium at four sites. Cadmium and copper concentrations exceeded the National Contaminant Biomonitoring Program 85th percentile in fish from six sites. Average concentrations of selenium in adult brine flies (33.7 mg/g dry weight) were elevated above concentrations in other
A simple daily soil-water balance model for estimating the spatial and temporal distribution of groundwater recharge in temperate humid areas

2007-01-01

Quantifying the spatial and temporal distribution of natural groundwater recharge is usually a prerequisite for effective groundwater modeling and management. As flow models become increasingly utilized for management decisions, there is an increased need for simple, practical methods to delineate recharge zones and quantify recharge rates. Existing models for estimating recharge distributions are data intensive, require extensive parameterization, and take a significant investment of time in order to establish. The Wisconsin Geological and Natural History Survey (WGNHS) has developed a simple daily soil-water balance (SWB) model that uses readily available soil, land cover, topographic, and climatic data in conjunction with a geographic information system (GIS) to estimate the temporal and spatial distribution of groundwater recharge at the watershed scale for temperate humid areas. To demonstrate the methodology and the applicability and performance of the model, two case studies are presented: one for the forested Trout Lake watershed of north central Wisconsin, USA and the other for the urban-agricultural Pheasant Branch Creek watershed of south central Wisconsin, USA. Overall, the SWB model performs well and presents modelers and planners with a practical tool for providing recharge estimates for modeling and water resource planning purposes in humid areas. ??

occurrence of sinkholes (number of sinkholes/km2 year). Such spatial and temporal predictions, frequently derived from limited records and based on the assumption that past sinkhole activity may be extrapolated to the future, are non-corroborated hypotheses. Validation methods allow us to assess the predictive capability of the susceptibility maps and to transform them into probability maps. Avoiding the most hazardous areas by preventive planning is the safest strategy for development in sinkhole-prone areas. Corrective measures could be applied to reduce the dissolution activity and subsidence processes. A more practical solution for safe development is to reduce the vulnerability of the structures by using subsidence-proof designs. ?? 2007 Springer-Verlag.

A finite area scheme for shallow granular flows on three-dimensional surfaces

Science.gov (United States)

Rauter, Matthias

2017-04-01

Shallow granular flow models have become a popular tool for the estimation of natural hazards, such as landslides, debris flows and avalanches. The shallowness of the flow allows to reduce the three-dimensional governing equations to a quasi two-dimensional system. Three-dimensional flow fields are replaced by their depth-integrated two-dimensional counterparts, which yields a robust and fast method [1]. A solution for a simple shallow granular flow model, based on the so-called finite area method [3] is presented. The finite area method is an adaption of the finite volume method [4] to two-dimensional curved surfaces in three-dimensional space. This method handles the three dimensional basal topography in a simple way, making the model suitable for arbitrary (but mildly curved) topography, such as natural terrain. Furthermore, the implementation into the open source software OpenFOAM [4] is shown. OpenFOAM is a popular computational fluid dynamics application, designed so that the top-level code mimics the mathematical governing equations. This makes the code easy to read and extendable to more sophisticated models. Finally, some hints on how to get started with the code and how to extend the basic model will be given.

Full Text Available Gudrun-Axeli Knapp hat mit ihrem Sammelband eine beeindruckende und überaus umfangreiche Werkschau aus 25 Jahren feministischer Theoriebildung vorgelegt. Der Band ist in vier thematische Blöcke unterteilt, die um Weiblichkeitskritik, feministische Aneignungen der Kritischen Theorie, Intersektionalität und die Frage nach der Gestalt feministischer (theoretischer Kritik kreisen. Dabei überzeugt die Autorin nicht nur durch ihre sorgfältigen wie streitbaren Argumentationen und Auseinandersetzungen im Terrain feministischer Theorie; reizvoll gestaltet sich überdies das Nachspüren jener Denkfigur über die Einzelbeiträge des Sammelbands hinweg, die auch den Titel des Bandes prägt: „im Widerstreit“. Damit legt Knapp auch Umrisse einer Programmatik feministischer Kritik vor.With her collection, Gudrun-Axeli Knapp presents an impressive and exceptionally extensive retrospective on 25 years of feminist theorizing. The volume is subdivided into four subject areas, which deal with femininity criticism, feminist appropriations of critical theory, intersectionality, and the question of the nature of feminist (theoretical criticism. The author does not only impress with her thorough yet also provocative argumentations and examinations of the terrain of feminist theory; but the figure of thought that she traces across all articles and that coins the collection’s title is also very appealing: “in conflict”. In doing so, Knapp does also outline aims and objectives of feminist criticism.

Full Text Available La inmunidad contra el virus de la hepatitis A (VHA se debe en primera instancia a la inducción de anticuerpos neutralizantes. Disponer de ensayos de neutralización es indispensable para evaluar nuevos candidatos vacunales contra este patógeno. En el presente trabajo se desarrolló un ensayo de neutralización in vitro que permitió evaluar la inmunogenicidad de mimotopos del VHA obtenidos mediante la tecnología de expresión en fagos al ser inmunizados ratones Balb/c. Diferentes diluciones de anticuerpos se incubaron con 103 o 102 Dosis Infecciosas en Cultivo de Tejidos 50% (DICT50 del clon citopático HM175/18f de VHA, y se inocularon en placas con células FRhK4. Después de 7 días de incubación el título neutralizante se determinó como el recíproco de la dilución del suero capaz de reducir la multiplicación viral al 50%. Tanto 103 como 102 DICT50 fueron neutralizadas por el anticuerpo monoclonal 7E7 y los sueros humanos (A12 y A31 positivos a anticuerpos anti-VHA. Los controles negativos del ensayo no neutralizaron al virus. Los títulos neutralizantes de los sueros de ratones inmunizados con fagos portadores de mimotopos de VHA oscilaron entre 4 y 16, mientras que los sueros preinmunes y los de ratones inmunizados con fago salvaje M13 no neutralizaron la infectividad viral. Este ensayo de neutralización resultó adecuado para la evaluación de los inmunógenos propuestos

Una herramienta importante para estudios en fisiología y áreas correlacionadas es la aplicación de modelos experimentales utilizando animales. Entretanto, todavía son restrictas las investigaciones destinadas a investigar protocolos de evaluación en ratones. El objetivo del presente estudio ha sido el de verificar si MFEL es dependiente del ergómetro utilizado para la evaluación aerobia de ratones. Para eso, 40 ratones Wistar adultos fueron evaluados en dos diferentes ejercicios: natación y carrera en faja ergo métrica. En ambos, la MFEL fue verificada después de la aplicación de 4 tests continuos, en diferentes intensidades, con duración de 25 minutos, separados por intervalos de 48 horas. En todos los tests hubo colecta sanguínea de la cola de los animales a cada 5 minutos de ejercicio para analizar el lactato sanguíneo. Los tests de natación ocurrieron en un tanque cilíndrico profundo, con el agua a temperatura de 31 ± 1°C. Las cargas adoptadas para los tests fueron 4,5; 5,0; 5,5; 6,0% del peso corporal, atadas al dorso de los animales. Para la determinación de la MFEL en carreras, hubo una selección de los ratones corredores y las velocidades de los tests fueron de 15, 20, 25, 30 m.min-1. La MFEL fue interpretada como la más alta intensidad de ejercicio en la que el aumento de lactacidemia fue igual o inferior a 1mM, del 10° al 25° minuto. Anova one-way identificó diferencias entre las concentraciones de lactato sanguíneo en los diversos tiempos de ejercicio y ergómetros.

Además, se encontró que el paso por el tracto digestivo de las 2 especies de ratones no tiene efecto significativo (p= 0.067 en la actividad metabólica esporal de R. aff. cuprea, sugiriendo que estos ratones silvestres podrían ser dispersores efectivos de las esporas del hongo epigeo en el Parque Nacional La Malinche.The mycophagy by rodents in hypogeous fungal species has been widely documented in different ecosystems around the world. However, the consumption of epigeos fungi by this group has been poorly studied. In this study we evaluated the mycophagy by 2 mice species (Neotomodon alstoni and Peromyscus maniculatus in the epigeous ectomycorrhizal fungi Russula aff. cuprea. Experimentally tests were carried out to see if these mice species have a preference to consume a specific structure of the fungus (pileus, hymenium or stipe. Also, we analyzed if the passage of this fungus through the digestive tract has an effect on the sporal metabolic activity. Our results indicate that although the whole sporocarp can be consumed, the hymenium (fertile part of the sporocarp was the first structure selected by both mice species. Furthermore, we found that the

Durante el curso de la infección primaria en ratones, se observa una parasitemia relativamente baja y de corta duración. Los mismos muestran durante la primera reinfección una parasitemia escasa de cuatro días de duración, siendo resistentes a las sucesivas reinfecciones con T. rangeli. Los ejemplares de D. marsupialis exhiben una parasitemia de más larga duración, pero con un nivel de parásitos sanguícolas mucho menor que el detectado en el modelo ratón, siendo la respuesta a las reinfecciones similar a la observada en ratones. Se detectan anticuerpos hemaglutinantes en los sueros inmunes de ratones y Didelphis marsupialis, sometidos a la reinfección por T. rangeli. Se especula sobre la posible acción sinérgica de una respuesta inmune en el sitio de deposición en contra de las formas metacíclicas de T. rangeli y la acción de anticuerpos circulantes en contra de las formas sanguícolas, para explicar la resistencia de ambos modelos a las reinfecciones por T. rangeli.Under experimental conditions, the course of the infection and the response to the reinfection by Trypanosoma rangeli in mice and Didelphis marsupialis, are studied.

Uranium favorability of the Sangre de Cristo Formation (Pennsylvanian-Permian) in the Las Vegas basin has been evaluated. The Las Vegas basin project area, located in Colfax, Mora, and San Miguel Counties, New Mexico, comprises about 3,489 sq mi. The formation contains sedimentologic and stratigraphic characteristics that are considered favorable for uranium deposition. Field investigations consisted of section measuring, rock sampling, and ground radiometric reconnaissance. North-south and east-west cross sections of the basin were prepared from well logs and measured sections. Petrographic, chemical, and spectrographic analyses were conducted on selected samples. Stratigraphic and sedimentologic information were used to determine depositional environments. The most favorable potential host rocks include red to pink, coarse-grained, poorly sorted, feldspathic to arkosic lenticular sandstones with stacked sandstone thicknesses of more than 20 ft and sandstone-to-shale ratios between 1:1 and 2:1. The sandstone is interbedded with mudstone and contains carbonaceous debris and anomalous concentrations of uranium locally. Areas of maximum favorability are found in a braided-stream, alluvial-plain depositional environment in the north-central part of the Las Vegas basin. There, carbonaceous material is well preserved, probably due to rapid subsidence and burial. Furthermore, uranium favorability is highest in the lower half of the formation because carbonaceous wood and plant fragments, as well as known uranium deposits, are concentrated in this zone. Piedmont deposits in the north and east, and meander-belt, alluvial-plain deposits in the south, are not considered favorable because of the paucity of uranium deposits and a minimum of carbonaceous material

Con el objeto de determinar si el Trypanosoma musculi ejerce procesos de inmunosupresión sobre Toxoplasma gondii se realizó un experimento en el que se inocularon ratones Swiss con T. musculi cuatro, cinco, seis y siete días previos a la infección con T. gondii, ocurriendo la inmunosupresión cuando la inoculación con T. musculi fue hecha cuatro días antes. Además, la cantidad de tripomastigotos inoculados no influyó en el proceso. Se probaron tres cepas de T. gondii aisladas de las heces de un gato casero (TFC, de un Leopardus pardalis (TLP, de un Leopardus wiedii y de la carne de un Bos taurus (TBT. La cepa TLP resultó ser muy patógena, matando a los animales en un tiempo corto, independientemente de la inoculación con T. musculi; para las otras cepas se mantuvo el patrón de inmunosupresión en los ratones. Se reporta entonces un modelo experimental de inmunosupresión, aspecto muy en boga en este momento, por su relación con enfermedades que inducen esta condición en el ser humano, especialmente a enfermedades como el cáncer y el SIDA. Este modelo es más fácil de aplicar experimentalmente que el correspondiente con T. lewisi previamente descrito, el cual usa ratas blancas de más difícil manejo que los ratones usados en este estudio.

; they also verified that the journals were using the APC model by visiting each journal’s website. Because of the large number of subject areas of the identified journals, the researchers decided to classify the journals into four broader categories: Health Sciences, Life Sciences, Natural Sciences, and Social Sciences and Humanities. To calculate the impact of OA papers, citation per paper (CPP was calculated for each subject area. Impact values were calculated on an annual basis as well. The researchers calculated the citation advantage of OA articles as the “difference between the open access and toll access impacts in terms of a percentage of the latter” (p. 585. Main Results – The authors categorized their findings according to three themes: the growth of APC funded OA papers, the number of OA papers by discipline, and citation advantage of OA vs. TA in general and by subject area. Together, Springer and Elsevier published 18,654 OA papers in the APC journals; this number represents 4.7% of the 396,760 papers published between 2007 and 2011. While the number of OA and TA papers has been growing annually, the number of OA papers has been growing more rapidly compared to the TA papers. In terms of subject areas, Life Sciences had the largest number of OA and TA papers (184,315, followed by Health Sciences (149,341, Natural Sciences (121,274, and Social Sciences and Humanities (42,824. Natural Sciences had the most OA papers (5.7% in terms of the number of papers in this subject area being OA papers, followed by Social Sciences and Humanities (5.2%, Health Sciences (4.6% and Life Sciences (3.6%. Overall, the researchers found that the impact values of OA papers were larger than those of the TA papers for each year examined. In considering subject areas, in all disciplines except Life Sciences, the most highly cited paper in the field is an OA paper. In Life Sciences, the most highly cited TA paper had 2,215 citations, compared to the OA paper, which had 1

Springer An étude on global vacuum energy sequester

2017-09-18

Recently two of the authors proposed a mechanism of vacuum energy sequester as a means of protecting the observable cosmological constant from quantum radiative corrections. The original proposal was based on using global Lagrange multipliers, but later a local formulation was provided. Subsequently other interesting claims of a different non-local approach to the cosmological constant problem were made, based again on global Lagrange multipliers. We examine some of these proposals and find their mutual relationship. We explain that the proposals which do not treat the cosmological constant counterterm as a dynamical variable require fine tunings to have acceptable solutions. Furthermore, the counterterm often needs to be retuned at every order in the loop expansion to cancel the radiative corrections to the cosmological constant, just like in standard GR. These observations are an important reminder of just how the proposal of vacuum energy sequester avoids such problems.
Multiscale, multispectral and multitemporal satellite data to identify archaeological remains in the archaeological area of Tiwanaku (Bolivia)

Masini, Nicola; Lasaponara, Rosa

The aim of this paper is to investigate the cultural landscape of the archaeological area of Tiwanaku (Bolivia) using multiscale, multispectral and multitemporal satellite data. Geospatial analysis techniques were applied to the satellite data sets in order to enhance and map traces of past human activities and perform a spatial characterization of environmental and cultural patterns. In particular, in the Tiwanaku area, the approach based on local indicators of spatial autocorrelation (LISA) applied to ASTER data allowed us to identify traces of a possible ancient hydrographic network with a clear spatial relation with the well-known moat surrounding the core of the monumental area. The same approach applied to QuickBird data, allowed us to identify numerous traces of archaeological interest, in Mollo Kontu mound, less investigated than the monumental area. Some of these traces were in perfect accordance with the results of independent studies, other were completely unknown. As a whole, the detected features, composing a geometric pattern with roughly North-South orientation, closely match those of the other residential contexts at Tiwanaku. These new insights, captured from multitemporal ASTER and QuickBird data processing, suggested new questions on the ancient landscape and provided important information for planning future field surveys and archaeogeophyical investigations.

Objective rapid delineation of areas at risk from block-and-ash pyroclastic flows and surges

2009-01-01

Assessments of pyroclastic flow (PF) hazards are commonly based on mapping of PF and surge deposits and estimations of inundation limits, and/or computer models of varying degrees of sophistication. In volcanic crises a PF hazard map may be sorely needed, but limited time, exposures, or safety aspects may preclude fieldwork, and insufficient time or baseline data may be available for reliable dynamic simulations. We have developed a statistically constrained simulation model for block-and-ash type PFs to estimate potential areas of inundation by adapting methodology from Iverson et al. (Geol Soc America Bull 110:972-984, (1998) for lahars. The predictive equations for block-and-ash PFs are calibrated with data from several volcanoes and given by A = (0.05 to 0.1) V2/3, B = (35 to 40) V2/3, where A is cross-sectional area of inundation, B is planimetric area and V is deposit volume. The proportionality coefficients were obtained from regression analyses and comparison of simulations to mapped deposits. The method embeds the predictive equations in a GIS program coupled with DEM topography, using the LAHARZ program of Schilling (1998). Although the method is objective and reproducible, any PF hazard zone so computed should be considered as an approximate guide only, due to uncertainties on the coefficients applicable to individual PFs, the authenticity of DEM details, and the volume of future collapses. The statistical uncertainty of the predictive equations, which imply a factor of two or more in predicting A or B for a specified V, is superposed on the uncertainty of forecasting V for the next PF to descend a particular valley. Multiple inundation zones, produced by simulations using a selected range of volumes, partly accommodate these uncertainties. The resulting maps show graphically that PF inundation potentials are highest nearest volcano sources and along valley thalwegs, and diminish with distance from source and lateral distance from thalweg. The model does

With the increase in popularity of the use of cosmetic fillers in plastic and esthetic surgery, the possibility of severe ocular complications should not be neglected. Of the fillers used, autologous fat is the most common to cause permanent visual deterioration, one of the most severe complications associated with the use of cosmetic fillers. Here we present the first report of a complete recovery of visual acuity from an instance of visual loss with no light perception caused by ophthalmic artery occlusion of the right eye following autologous fat injection in the facial area. Immediate ophthalmological intervention and comprehensive therapy with prostaglandins and vinpocetine made it possible to restore retinal perfusion and achieve complete recovery of visual acuity. Awareness of the iatrogenic artery occlusions associated with facial fillers and the need for immediate treatment should be popularized among injectors to prevent devastating consequences, such as permanent vision loss.

Schmidt College of Medicine, Florida Atlantic University, FL, 3North Main Radiation Oncology, Warren Alpert School of Medicine, Brown University, RI, USA Abstract: Nonmelanoma skin cancer (NMSC is an increasing health care issue in the United States, significantly affecting quality of life and impacting health care costs. Radiotherapy has a long history in the treatment of NMSC. Shortly after the discovery of X-rays and 226Radium, physicians cured patients with NMSC using these new treatments. Both X-ray therapy and brachytherapy have evolved over the years, ultimately delivering higher cure rates and lower toxicity. Electronic brachytherapy for NMSC is based on the technical and clinical data obtained from radionuclide skin surface brachytherapy and the small skin surface applicators developed over the past 25 years. The purpose of this review is to introduce electronic brachytherapy in the context of the history, data, and utilization of traditional radiotherapy and brachytherapy.

A curvature theory for discrete surfaces based on mesh parallelity

KAUST Repository

Bobenko, Alexander Ivanovich

2009-12-18

We consider a general theory of curvatures of discrete surfaces equipped with edgewise parallel Gauss images, and where mean and Gaussian curvatures of faces are derived from the faces\\' areas and mixed areas. Remarkably these notions are capable of unifying notable previously defined classes of surfaces, such as discrete isothermic minimal surfaces and surfaces of constant mean curvature. We discuss various types of natural Gauss images, the existence of principal curvatures, constant curvature surfaces, Christoffel duality, Koenigs nets, contact element nets, s-isothermic nets, and interesting special cases such as discrete Delaunay surfaces derived from elliptic billiards. © 2009 Springer-Verlag.

Flow area optimization in point to area or area to point flows

International Nuclear Information System (INIS)

Ghodoossi, Lotfollah; Egrican, Niluefer

2003-01-01

This paper deals with the constructal theory of generation of shape and structure in flow systems connecting one point to a finite size area. The flow direction may be either from the point to the area or the area to the point. The formulation of the problem remains the same if the flow direction is reversed. Two models are used in optimization of the point to area or area to point flow problem: cost minimization and revenue maximization. The cost minimization model enables one to predict the shape of the optimized flow areas, but the geometric sizes of the flow areas are not predictable. That is, as an example, if the area of flow is a rectangle with a fixed area size, optimization of the point to area or area to point flow problem by using the cost minimization model will only predict the height/length ratio of the rectangle not the height and length itself. By using the revenue maximization model in optimization of the flow problems, all optimized geometric aspects of the interested flow areas will be derived as well. The aim of this paper is to optimize the point to area or area to point flow problems in various elemental flow area shapes and various structures of the flow system (various combinations of elemental flow areas) by using the revenue maximization model. The elemental flow area shapes used in this paper are either rectangular or triangular. The forms of the flow area structure, made up of an assembly of optimized elemental flow areas to obtain bigger flow areas, are rectangle-in-rectangle, rectangle-in-triangle, triangle-in-triangle and triangle-in-rectangle. The global maximum revenue, revenue collected per unit flow area and the shape and sizes of each flow area structure have been derived in optimized conditions. The results for each flow area structure have been compared with the results of the other structures to determine the structure that provides better performance. The conclusion is that the rectangle-in-triangle flow area structure

Wintering area DDE source to migratory white-faced ibis revealed by satellite telemetry and prey sampling

Science.gov (United States)

Yates, M.A.; Fuller, M.R.; Henny, C.J.; Seegar, W.S.; Garcia, Jorge H.

2010-01-01

Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds. A portion of the migratory white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada continues to be exposed to dichloro-diphenyldichloro-ethylene (DDE) with no change, which is unusual, observed in egg concentrations between 1985 and 2000. About 45-63% of the earliest nesting segment shows reduced reproductive success correlated with elevated egg concentrations of >4 ??g/g wet weight (ww). Local prey (primarily earthworms) near nests contained little DDE so we tracked the migration and wintering movements of 20 adult males during 2000-2004 to determine the possible source. At various wintering sites, we found a correlation (r 2 = 0.518, P = 0.0125, N = 11) between DDE in earthworm composites and DDE in blood plasma of white-faced ibis wintering there, although the plasma was collected on their breeding grounds soon after arrival. The main source of DDE was wintering areas in the Mexicali Valley of Baja California Norte, Mexico, and probably the adjacent Imperial Valley, California, USA. This unusual continuing DDE problem for white-faced ibis is associated with: the long-term persistence in soil of DDE; the earthworms' ability to bioconcentrate DDE from soil; the proclivity of white-faced ibis to feed on earthworms in agricultural fields; the species's extreme sensitivity to DDE in their eggs; and perhaps its life history strategy of being a "capital breeder". We suggest surveying and sampling white-faced ibis eggs at nesting colonies, especially at Carson Lake, to monitor the continuing influence of DDE. ?? 2009 Springer Science+Business Media, LLC.

MÉTODOS: Cuarenta ratones anestesiados, Sprague-Dawley machos, fueron cateterizados intratecalmente. Los valores basales de los testes TF y HP fueron medidos antes y después del cateterismo. Treinta y seis ratones cateterizados con éxito fueron distribuidos en cuatro grupos. El Grupo B recibió 10 µg de bupivacaína, el Grupo BD3 recibió 10 µg de bupivacaína + 3 µg de dexmedetomidina, el Grupo BD10 recibió 10 µg de bupivacaína + 10 µg de dexmedetomidina y el Grupo Control recibió 10 µL de líquido cefalorraquídeo artificial. Los test TF y HP se hicieron entre cinco y 300 minutos a partir de la administración de los fármacos. Veinte y cuatro horas después de la administración, los ratones fueron sacrificados y se les retiraron las médulas espinales y las raíces nerviosas para investigación patológica. RESULTADOS: Los valores basales de los test TF y HP no fueron estadísticamente diferentes entre los grupos (6,8 ± 0,15 s. Las latencias de TF y HP en el Grupo Control no tenían ninguna alteración significativa durante el estudio.

The U.S. Geological Survey has completed an assessment of the potential geologic carbon dioxide storage resources in the onshore areas of the United States. To provide geological context and input data sources for the resources numbers, framework documents are being prepared for all areas that were investigated as part of the national assessment. This report, chapter M, is the geologic framework document for the Uinta and Piceance, San Juan, Paradox, Raton, Eastern Great, and Black Mesa Basins, and subbasins therein of Arizona, Colorado, Idaho, Nevada, New Mexico, and Utah. In addition to a summary of the geology and petroleum resources of studied basins, the individual storage assessment units (SAUs) within the basins are described and explanations for their selection are presented. Although appendixes in the national assessment publications include the input values used to calculate the available storage resource, this framework document provides only the context and source of the input values selected by the assessment geologists. Spatial-data files of the boundaries for the SAUs, and the well-penetration density of known well bores that penetrate the SAU seal, are available for download with the release of this report.

Springer Autopsy of measurements with the ATLAS detector at the LHC

CERN Document Server

Beauchemin, Pierre-Hugues

2017-01-01

A lot of attention has been devoted to the study of discoveries in high energy physics (HEP), but less on measurements aiming at improving an existing theory like the standard model of particle physics, getting more precise values for the parameters of the theory or establishing relationships between them. This paper provides a detailed and critical study of how measurements are performed in recent HEP experiments, taking examples from differential cross section measurements with the ATLAS detector at the LHC. This study will be used to provide an elucidation of the concept of event used in HEP, in order to determine what constitutes an observation and what does not. It will highlight the essential place taken by theory-ladenness in order to produce observational facts, and will show how uncertainty and sensitivity estimates constitute an operational approach to robustness, inside the practice of science, avoiding potential circularity problem traditionally implied by theory-ladenness. This is in contrast to ...

Geology along Mosca Pass Trail, Great Sand Dunes National Park and Preserve, Colorado

Lindsey, David A.; Klein, Terry L.; Valdez, Andrew; Webster, Robert J.

Mosca Pass Trail takes the hiker on a journey into the Earth's crust. Here you can see the results of tremendous tectonic forces that bend and tear rocks apart and raise mountain ranges. The trail begins near the Sangre de Cristo fault, which separates the Sangre de Cristo Range from the San Luis Valley. The valley is part of the Rio Grande rift, a series of fault basins extending from southern New Mexico to central Colorado, wherein the Earth's crust has been pulled apart during the last 30 million years. Thousands of feet of sediment, brought by streams mostly from the Sangre de Cristo Range, fill the San Luis Valley beneath the Great Sand Dunes. The trail ends at Mosca Pass overlooking Huerfano Park. The park is part of the larger Raton Basin, formed by compression of the Earth's crust during the Laramide orogeny, which occurred 70–40 million years ago. Massive highlands, the remnants of which are preserved in the Sangre de Cristo Range, were uplifted and pushed over the western side of the Raton Basin. Streams eroded the highland as it rose and filled the Raton Basin with sediment. After the sediment was compacted and cemented to form sedimentary rock, the Huerfano River and other streams began to excavate the basin. Over an unknown but long timespan that probably lasted millions of years, relatively soft sedimentary rocks were removed by the river to form the valley we call "Huerfano Park." Between the ends of the trail, the hiker walks through an erosional "window," or opening, into red sedimentary rocks overridden by gneiss, a metamorphic rock, during the Laramide orogeny. This window gives the hiker a glimpse into the Laramide highland of 70–40 million years ago that preceded the present-day Sangre de Cristo Range. The window is the focus of this trail guide. At the east end of the trail, near Mosca Pass, another trail follows the ridgeline south to Carbonate Mountain. Immediately after reaching the first summit above tree line, this trail crosses a

The consumption of EVOO in Mediterranean countries has shown beneficial effects. A wide range of evidence indicates that the phenolic compounds present in EVOO are endowed with anti-inflammatory properties. In this work, we evaluated the effects of dietary EVOO and treatment with its phenolic extract (PE) in a model of RA, the collagen-induced arthritis (CIA) in mice. On day 0, DBA-1/J mice were immunized with bovine collagen type II (CII). On day 21, the mice received a booster injection. We have demonstrated that EVOO and its PE decreases joint edema, cell migration, cartilage degradation and bone erosion. Our data indicate that dietary EVOO and PE treatment inhibit JNK, p38 and signal transducer and STAT-3. In addition, both EVOO and PE decrease NF-κB translocation leading to the down-regulation of the arthritic process. These results support the interest of natural diet components in the development of therapeutic products for arthritic conditions. [Spanish] El consumo de Aceite de oliva virgen extra (AOVE) enlos países mediterráneos ha demostrado tener efectos beneficiosos. Una amplia gama de pruebas indica que los compuestos fenólicos presentes en el AOVE tienen propiedades anti-inflamatorias.

En el día 0, los ratones DBA-1/J se inmunizaron con colágeno bovino tipo II (CII). En el día 21, los ratones recibieron una inyección de refuerzo. Hemos demostrado que el AOVE y su FP disminuyen conjuntamente el edema, la migración celular, la degradación del cartílago y erosión ósea. Nuestros datos indican que la dieta con AOVE y el tratamiento con FP inhiben JNK, p38 y el transductor de señal y activador de la transcripción 3 (STAT-3). Además, tanto el AOVE como la FP disminuyen la translocación NF-κB que conduce a la mejora del proceso artrítico. Estos

Resultados. En Rhodnius pictipes se encontró un mayor porcentaje de infección intestinal que en las otras especies. Se detectaron epimastigotes y tripomastigotes en la hemolinfa de las cuatro especies, y se encontró que el parasitismo fue menor en las especies del linaje R. robustus. Rhodnius robustus y R. neglectus no transmitían T. rangeli a ratones por picadura: después de la disección, sus glándulas no estaban infectadas. Solo un espécimen de R. nasutus y dos de R. pictipes transmitieron el parásito por la picadura. La tasa de infección glandular fue de 16 % para R. pictipes y de 4 % para R. nasutus. Conclusiones. La capacidad infecciosa (hemolinfática, intestinal y glandular y la transmisión de T. rangeli (SC-58/KP1- fueron mayores y más eficientes en R. pictipes. Estos resultados refuerzan la hipótesis de que estos triatominos actúan como filtros biológicos en la transmisión de T. rangeli.

Many families come to therapy struggling with the negative consequence of social inequity. Family therapy modalities have been developed to address these negative consequences and attend to power and social equity (Transformative family therapy: Just families in a just society. Boston, MA: Pearson Education; Socio-emotional relationship therapy. New York, NY: Springer). We argue that many family therapy modalities can be adapted to include social equity (Applying critical social theory in family therapy practice. AFTA Springer Series. New York, NY: Springer Publishing). Specifically, cognitive behavioral family therapy can be used to address the inequality in social systems that negatively affect the family system. We focus on schema formation and suggest an emphasis on societal schemas within the therapy milieu as a tool to help families see how societal inequality can affect the problems faced in family life. © 2016 American Association for Marriage and Family Therapy.

Radioactive contamination of the environment following the Chernobyl accident still provide a substantial impact on the population of affected territories in Belarus, Russia, and Ukraine. Reduction of population exposure can be achieved by performing remediation activities in these areas. Resulting from the IAEA Technical Co-operation Projects with these countries, the program ReSCA (Remediation Strategies after the Chernobyl Accident) has been developed to provide assistance to decision makers and to facilitate a selection of an optimized remediation strategy in rural settlements. The paper provides in-depth description of the program, its algorithm, and structure. © Springer-Verlag 2010

In this introduction to a special subsection of Theoretical Medicine and Bioethics comprising separate reviews of the Springer Handbook of the Philosophy of Medicine, The Routledge Companion to Philosophy of Medicine, and The Bloomsbury Companion to Contemporary Philosophy of Medicine, I compare the three texts with respect to their overall organization and their approach to the relation between the science and the art of medicine. I then indicate two areas that merit more explicit attention in developing a comprehensive philosophy of medicine going forward: health economics and systematic relations within the field as a whole. The reviews that follow speak for themselves.

El D-004 es un extracto lipídico extraído a partir del fruto de la palma real (Roystonea regia, inhibe la 5 a-reductasa y previene la hiperplasia prostática benigna, y muestra un efecto antidepresivo moderado en el ensayo de nado forzado y suspensión por la cola. Objetivo: comparar el efecto del D-004 con la imipramina y la sertralina sobre la duración de las conductas de inmovilidad, nado y escalado en el ensayo de nado forzado. Métodos: se distribuyeron los ratones en ocho grupos: control (vehículo, tres tratados con D-004 (100, 250 y 500 mg/kg, dos con sertralina y dos con imipramina (30 y 50 mg/kg respectivamente. Estos se colocaron en un cilindro de cristal que contenía agua a una altura de 6 cm y se cuantificaron las conductas. Resultados: la administración oral de D-004 (100, 250 y 500 mg/kg durante 14 días redujo significativamente el tiempo de inmovilidad con respecto al grupo control (17, 22 y 25 % y aumentó significativamente la conducta de nado en 1,58, 1,68 y 1,74 veces. Este efecto resulta moderado (25 % comparado con las reducciones alcanzadas por la sertralina y la imipramina (³ 60 %. Las dosis mayores (250 y 500 mg/kg ocasionaron incrementos de la conducta de escalado, 2,79 y 3,55 veces superiores a la del grupo control, lo que mostró semejanza con la imipramina, aunque con una menor eficacia. Conclusiones: el D-004 ejerce un moderado efecto antidepresivo, lo que pudiera contribuir al manejo de los pacientes con hiperplasia prostática benigna en los cuales se informa coincidencia de cuadros depresivos.Introduction: Finasteride is a 5 a-reductase inhibitor to treat benign prostatic hyperplasia (BPH and one of the adverse effects is the increase of depressive symptoms.

Full Text Available Mediante cromatografía de intercambio catiónico en CM-Sephadex C-25 (16 x 1,1 cm con buffer acetato de amonio 0,05 M a pH 7, del veneno del escorpión Brachistosternus ehrenbergii fue aislada una proteína con acción tóxica sobre ratones albinos. En este sistema la toxina interactúa con el gel y es eluida al final luego de usar el mismo buffer conteniendo NaCl 0,6M. La toxina fue denominada Be1 y es una proteína básica que constituye el 8,1% de la proteína total del veneno. La pureza de la toxina fue evaluada por electroforesis en condiciones nativas, de acuerdo al método de Reisfeld, y en condiciones denaturantes por el método de Schägger y von Jagow, determinándose que la toxina es una sola cadena polipeptídica de 6,3 kDa. La inoculación de 60 μg de toxina en ratones albinos, vía intraperitoneal, genera la aparición de algunos signos locales como hipersecreción salival, seguido por afección respiratoria, arrastre de las patas posteriores, hasta finalmente al cabo de 2 horas, producir la muerte. Vía intramuscular (7,6 μg, Be1 produce parálisis temporal de la extremidad inoculada. La toxina no tiene actividades de fosfolipasa, proteasa, acetilcolinesterasa ni actividad inhibidora de acetilcolinesterasa.

Recent unethical business practices of some corporations and the overall loss of confidence by the public in corporate leadership have given rise to a unique leadership model--one that focuses on spirituality. "Ninety percent of our diverse American population and health-care workforce have spiritual and religious beliefs. While these beliefs may be mystical, religious, or secular, there are many common patterns that influence change and leadership within our organizations." So says Gary Strack, CHE, president and chief executive officer of Boca Raton (FL) Community Hospital. Strack presented a seminar on the topic at ACHE's 2003 Congress on Healthcare Management.

This SpringerBrief focuses on the network capacity analysis of VANETs, a key topic as fundamental guidance on design and deployment of VANETs is very limited. Moreover, unique characteristics of VANETs impose distinguished challenges on such an investigation. This SpringerBrief first introduces capacity scaling laws for wireless networks and briefly reviews the prior arts in deriving the capacity of VANETs. It then studies the unicast capacity considering the socialized mobility model of VANETs. With vehicles communicating based on a two-hop relaying scheme, the unicast capacity bound is deriv
Selection of material balance areas and item control areas

International Nuclear Information System (INIS)

1975-04-01

Section 70.58, ''Fundamental Nuclear Material Controls,'' of 10 CFR Part 70, ''Special Nuclear Material,'' requires certain licensees authorized to possess more than one effective kilogram of special nuclear material to establish Material Balance Areas (MBAs) or Item Control Areas (ICAs) for the physical and administrative control of nuclear materials. This section requires that: (1) each MBA be an identifiable physical area such that the quantity of nuclear material being moved into or out of the MBA is represented by a measured value; (2) the number of MBAs be sufficient to localize nuclear material losses or thefts and identify the mechanisms; (3) the custody of all nuclear material within an MBA or ICA be the responsibility of a single designated individual; and (4) ICAs be established according to the same criteria as MBAs except that control into and out of such areas would be by item identity and count for previously determined special nuclear material quantities, the validity of which must be ensured by tamper-safing unless the items are sealed sources. This guide describes bases acceptable to the NRC staff for the selection of material balance areas and item control areas. (U.S.)

Brodmann areas 44 and 45 are known as Broca's area; however, their true functional roles are still unknown. Recent developments in neuroimaging techniques revealed the structures and functions of Broca's area in detail. More specifically regarding language functions, sufficient evidence has been accumulated that this region subserves the center of syntactic processing, not necessarily motor functions. Here, we review a role of Broca's area as the grammar center, including other roles in nonlinguistic functions.

Climate influences the leaf area/sapwood area ratio in Scots pine.

Science.gov (United States)

Mencuccini, M; Grace, J

1995-01-01

We tested the hypothesis that the leaf area/sapwood area ratio in Scots pine (Pinus sylvestris L.) is influenced by site differences in water vapor pressure deficit of the air (D). Two stands of the same provenance were selected, one in western Scotland and one in eastern England, so that effects resulting from age, genetic variability, density and fertility were minimized. Compared with the Scots pine trees at the cooler and wetter site in Scotland, the trees at the warmer and drier site in England produced less leaf area per unit of conducting sapwood area both at a stem height of 1.3 m and at the base of the live crown, whereas stem permeability was similar at both sites. Also, trees at the drier site had less leaf area per unit branch cross-sectional area at the branch base than trees at the wetter site. For each site, the average values for leaf area, sapwood area and permeability were used, together with values of transpiration rates at different D, to calculate average stem water potential gradients. Changes in the leaf area/sapwood area ratio acted to maintain a similar water potential gradient in the stems of trees at both sites despite climatic differences between the sites.

A generalization of the convex Kakeya problem

KAUST Repository

Ahn, Heekap

2012-01-01

We consider the following geometric alignment problem: Given a set of line segments in the plane, find a convex region of smallest area that contains a translate of each input segment. This can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be turned through 360 degrees within this region. Our main result is an optimal Θ(n log n)-time algorithm for our geometric alignment problem, when the input is a set of n line segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then the optimum placement is when the midpoints of the segments coincide. Finally, we show that for any compact convex figure G, the smallest enclosing disk of G is a smallest-perimeter region containing a translate of any rotated copy of G. © 2012 Springer-Verlag Berlin Heidelberg.

Graves, T.A.; Farley, S.; Goldstein, M.I.; Servheen, C.

2007-01-01

We identified primary habitat and functional corridors across a landscape using Global Positioning System (GPS) collar locations of brown bears (Ursus arctos). After deriving density, speed, and angular deviation of movement, we classified landscape function for a group of animals with a cluster analysis. We described areas with high amounts of sinuous movement as primary habitat patches and areas with high amounts of very directional, fast movement as highly functional bear corridors. The time between bear locations and scale of analysis influenced the number and size of corridors identified. Bear locations should be collected at intervals ???6 h to correctly identify travel corridors. Our corridor identification technique will help managers move beyond the theoretical discussion of corridors and linkage zones to active management of landscape features that will preserve connectivity. ?? 2007 Springer Science+Business Media, Inc.
Should Broca's area include Brodmann area 47?

Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47 connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

MILDOS-AREA: An enhanced version of MILDOS for large-area sources

International Nuclear Information System (INIS)

Yuan, Y.C.; Wang, J.H.C.; Zielen, A.

1989-06-01

The MILDOS-AREA computer code is a modified version of the MILDOS code, which estimates the radiological impacts of airborne emissions from uranium mining and milling facilities or any other large-area source involving emissions of radioisotopes of the uranium-238 series. MILDOS-AREA is designed for execution on personal computers. The modifications incorporated in the MILDOS-AREA code provide enhanced capabilities for calculating doses from large-area sources and update dosimetry calculations. The major revision from the original MILDOS code is the treatment of atmospheric dispersion from area sources: MILDOS-AREA substitutes a finite element integration approach for the virtual-point method (the algorithm used in the original MILDOS code) when specified by the user. Other revisions include the option of using Martin-Tickvart dispersion coefficients in place of Briggs coefficients for a given source, consideration of plume reflection, and updated internal dosimetry calculations based on the most recent recommendations of the International Commission on Radiation Protection and the age-specific dose calculation methodology developed by Oak Ridge National Laboratory. This report also discusses changes in computer code structure incorporated into MILDOS-AREA, summarizes data input requirements, and provides instructions for installing and using the program on personal computers. 15 refs., 9 figs., 26 tabs

Full Text Available Las infecciones transmitidas por Flavivirus se encuentran entre las enfermedades transmisibles con mayor incidencia en el mundo. La mayoría de ellas se manifiestan clínicamente como un síndrome febril que puede estar o no acompañado de diversos síntomas. La severidad de estas infecciones es variable con casos asintomáticos y otros que pueden llegar a ser letales, La razón de esta variabilidad en la presentación clínica, se desconoce en humanos. En ratones se han identificado cepas susceptibles y cepas resistentes a la infección por algunos Flavivirus. Por clonación posicional se mapeó el gen responsable de la resistencia a virus West Nile en el cromosoma 5 de ratón y se identificó como oligoadenilato sintetasa 1b (Oas1 b. Este gen codifica una proteína que sintetiza oligómeros de adenina que activan la RNasaL, que a su vez degrada los RNAs virales. Células provenientes de ratones resistentes a la infección por Flavivirus producen menor cantidad de virus que su contraparte susceptible, Recientemente en humanos, se identificó un polimorfismo asociado con susceptibilidad a infección por virus West Nile en el gen de OasL. Sin embargo, el mecanismo bioquímico y molecular exacto por el cual se produce la susceptibilidad no ha sido completamente dilucidado, Este conocimiento permitiría aclarar aspectos de la fisiopatología de estas enfermedades y enfocar la terapéutica desde un punto de vista más específico.

Aiming at a dose reduction and a work efficiency improvement for nuclear power plants that have high dose regions, we have developed our system of wireless-communicating Area Monitor with Surveillance Camera, and have performed an on-site test. Now we are implementing this Area Monitor with Surveillance Camera for a use as a TV camera in the controlled-area, which enables a personal computer to simultaneously display two or more dose values and site live images on the screen. For the radiation detector of this Area Monitor System, our wireless-communicating dosimeter is utilized. Image data are transmitted via a wireless Local Area Network (LAN). As a test result, image transmission of a maximum of 20 frames per second has been realized, which shows that this concept is a practical application. Remote-site monitoring also has been realized from an office desk located within the non-controlled area, adopting a Japan's wireless phone system, PHS (Personal Handy Phone) for the transmission interface.

Background: In many countries gastric cancer has the highest incidence among the gastrointestinal cancers and is the second most common cancer in Iran. The aim of this study was to identify and map high risk gastric cancer regions at the county-level in Iran. Methods: In this study we analyzed gastric cancer data for Iran in the years 2003-2010. Areato- area Poisson kriging and Besag, York and Mollie (BYM) spatial models were applied to smoothing the standardized incidence ratios of gastric cancer for the 373 counties surveyed in this study. The two methods were compared in term of accuracy and precision in identifying high risk regions. Result: The highest smoothed standardized incidence rate (SIR) according to area-to-area Poisson kriging was in Meshkinshahr county in Ardabil province in north-western Iran (2.4,SD=0.05), while the highest smoothed standardized incidence rate (SIR) according to the BYM model was in Ardabil, the capital of that province (2.9,SD=0.09). Conclusion: Both methods of mapping, ATA Poisson kriging and BYM, showed the gastric cancer incidence rate to be highest in north and north-west Iran. However, area-to-area Poisson kriging was more precise than the BYM model and required less smoothing. According to the results obtained, preventive measures and treatment programs should be focused on particular counties of Iran. Creative Commons Attribution License

In accordance with DOE Regulations for Compliance with Floodplain/Wetlands Environmental Review Requirements, wetland surveys were conducted in selected areas within the K-25 Area of Responsibility during the summer of 1994. These areas are Mitchell Branch, Poplar Creek, the K-770 OU, Duct Island Peninsula, the Powerhouse area, and the K-25 South Corner. Previously surveyed areas included in this report are the main plant area of the K-25 Site, the K-901 OU, the AVLIS site, and the K-25 South Site. Wetland determinations were based on the USACE methodology. Forty-four separate wetland areas, ranging in size from 0.13 to 4.23 ha, were identified. Wetlands were identified in all of the areas surveyed with the exception of the interior of the Duct Island Peninsula and the main plant area of the K-25 Site. Wetlands perform functions such as floodflow alteration, sediment stabilization, sediment and toxicant retention, nutrient transformation, production export, and support of aquatic species and wildlife diversity and abundance. The forested, scrub-shrub, and emergent wetlands identified in the K-25 area perform some or all of these functions to varying degrees.
Complementarity and Area-Efficiency in the Prioritization of the Global Protected Area Network.

Peter Kullberg

Full Text Available Complementarity and cost-efficiency are widely used principles for protected area network design. Despite the wide use and robust theoretical underpinnings, their effects on the performance and patterns of priority areas are rarely studied in detail. Here we compare two approaches for identifying the management priority areas inside the global protected area network: 1 a scoring-based approach, used in recently published analysis and 2 a spatial prioritization method, which accounts for complementarity and area-efficiency. Using the same IUCN species distribution data the complementarity method found an equal-area set of priority areas with double the mean species ranges covered compared to the scoring-based approach. The complementarity set also had 72% more species with full ranges covered, and lacked any coverage only for half of the species compared to the scoring approach. Protected areas in our complementarity-based solution were on average smaller and geographically more scattered. The large difference between the two solutions highlights the need for critical thinking about the selected prioritization method. According to our analysis, accounting for complementarity and area-efficiency can lead to considerable improvements when setting management priorities for the global protected area network.

Selected trace element analysis for cadmium, copper, lead, and zinc in precipitation samples by inductively coupled plasma atomic emission Spectrometry (ICP) and by atomic absorption spectrometry with graphite furnace atomization (AAGF) have been evaluated. This task was conducted in conjunction with a longterm study of precipitation chemistry at high altitude sites located in remote areas of the southwestern United States. Coefficients of variation and recovery values were determined for a standard reference water sample for all metals examined for both techniques. At concentration levels less than 10 micrograms per liter AAGF analyses exhibited better precision and accuracy than ICP. Both methods appear to offer the potential for cost-effective analysis of trace metal ions in precipitation. ?? 1987 Springer-Verlag.

In North America, most Artemisia (Asteraceae) shrub species lack the ability to resprout after disturbances that remove aboveground biomass. We studied the response of one of the few resprouting Artemisia shrubs, Artemisia filifolia (sand sagebrush), to the effects of prescribed fires. We collected data on A. filifolia density and structural characteristics (height, canopy area, and canopy volume) in an A. filifolia shrubland in the southern Great Plains of North America. Our study sites included areas that had not been treated with prescribed fire, areas that had been treated with only one prescribed fire within the previous 5 years, and areas that had been treated with two prescribed fires within the previous 10 years. Our data were collected at time periods ranging from 1/2 to 5 years after the prescribed fires. Density of A. filifolia was not affected by one or two fires. Structural characteristics, although initially altered by prescribed fire, recovered to levels characteristic of unburned areas in 3-4 years after those fires. In contrast to most non-sprouting North American Artemisia shrub species, our research suggested that the resprouting A. filifolia is highly tolerant to the effects of fire. ?? 2011 Springer Science+Business Media B.V.
Three Gorges Reservoir Area: soil erosion under natural condition vs. soil erosion under current land use

Science.gov (United States)

Schönbrodt, Sarah; Behrens, Thorsten; Scholten, Thomas

2010-05-01

Apparently, the current most prominent human-induced example for large scale environmental impact is the Three Gorges Dam in China. The flooding alongside the Yangtze River, and its tributaries results in a vast loss of settlement and farmland area with productive, fertile valley soils. Due to the associated high land use dynamic on uphill-sites, the soil resources are underlying high land use pressure. Within our study, the soil erosion under natural conditions is compared to the soil erosion under current land use after the impoundment. Both were modeled using the empirical Universal Soil Loss Equation (USLE) which is able to predict long-term annual soil loss with limited data. The database consists of digital terrain data (45 m resolution DEM, erosive slope length based on Monte-Carlo-Aggregation according to Behrens et al. (2008)), field investigations of recent erosion forms, and literature studies. The natural disposition to soil erosion was calculated considering the USLE factors R, S, and K. The soil erosion under current land use was calculated taking into account all USLE factors. The study area is the catchment of the Xiangxi River in the Three Gorges Reservoir area. Within the Xiangxi Catchment (3,200 km²) the highly dynamic backwater area (580 km²), and two micro-scale study sites (Xiangjiaba with 2.8 km², and Quyuan with 88 km²) are considered more detailed as they are directly affected by the river impoundment. Central features of the Xiangxi Catchment are the subtropical monsoon climate, an extremely steep sloping relief (mean slope angle 39°, SD 22.8°) artificially fractured by farmland terraces, and a high soil erodibility (mean K factor 0.37, SD 0.13). On the catchment scale the natural disposition to soil erosion makes up to mean 518.0 t ha-1 a-1. The maximum potential soil loss of 1,730.1 t ha-1 a-1 under natural conditions is reached in the Quyuan site (mean 635.8 t ha-1 a-1) within the backwater area (mean 582.9 t ha-1 a-1). In the

However, this specialty has a unique particularity: the difficulties in Aesthetic Surgery training within the residency program. Despite the fact that the full title of the specialty is Plastic, Reconstructive, and Aesthetic Surgery and that Aesthetic Surgery is a part of the examination syllabus, the actual training in the specific area is limited. One of the solutions to this problem is Fellowships. The first author describes his personal experience with Aesthetic training and how it enhanced his knowledge in the area as well as the status of Fellowships in various training programs. This journal requires that authors assign a level of evidence to each article.

This environmental assessment has been prepared to assess potential environmental impacts associated with the US Department of Energy's proposed action: the salvage/demolition of the 200 West Area, 200 East Area, and 300 Area Steam Plants and steam distribution piping. Impact information will be used by the US Department of Energy, Richland Operations Office Manager, to determine if the proposed action is a major federal action significantly affecting the quality of the human environment. If the proposed action is determined to be major and significant, an environmental impact statement will be prepared. If the proposed action is determined not to be major and significant, a Finding of No Significant Impact (FONSI) will be issued and the action can proceed. The proposed action involves the salvage and demolition of the 200 West Area, 200 East Are, and 300 Area steam plants and their associated steam distribution piping, equipment, and ancillary facilities. Activities include the salvaging and recycling of all materials, wastes, and equipment where feasible, with waste minimization efforts utilized

Aims. This study evaluated the effects of L-PRF presence and implant surface texture on bone healing around immediately placed implants. Methods. The first mandibular molars of 8 beagle dogs were bilaterally extracted, and implants (Blossom™, Intra-Lock International, Boca Raton, FL) were placed in the mesial or distal extraction sockets in an interpolated fashion per animal. Two implant surfaces were distributed per sockets: (1) dual acid-etched (DAE, micrometer scale textured) and (2) micrometer/nanometer scale textured (Ossean™ surface). L-PRF (Intraspin system, Intra-Lock International) was placed in a split-mouth design to fill the macrogap between implant and socket walls on one side of the mandible. The contralateral side received implants without L-PRF. A mixed-model ANOVA (at α = 0.05) evaluated the effect of implant surface, presence of L-PRF, and socket position (mesial or distal), individually or in combination on bone area fraction occupancy (BAFO). Results. BAFO values were significantly higher for the Ossean relative to the DAE surface on the larger mesial socket. The presence of L-PRF resulted in higher BAFO. The Ossean surface and L-PRF presence resulted in significantly higher BAFO. Conclusion. L-PRF and the micro-/nanometer scale textured surface resulted in increased bone formation around immediately placed implants. PMID:28042577

north‐central Texas near Dallas–Fort Worth. The chance of having levels of ground motions corresponding to modified Mercalli intensity (MMI) VI or greater earthquake shaking is 2%–12% per year in north‐central Oklahoma and southern Kansas and New Madrid similar to the chance of damage at sites in high‐hazard portions of California caused by natural earthquakes. Hazard is also significant in the Raton basin of Colorado/New Mexico; north‐central Arkansas; Dallas–Fort Worth, Texas; and in a few other areas. Hazard probabilities are much lower (by about half or more) for exceeding MMI VII or VIII. Hazard is 3‐ to 10‐fold higher near some areas of active‐induced earthquakes than in the 2014 USGS National Seismic Hazard Model (NSHM), which did not consider induced earthquakes. This study in conjunction with the LandScan TM Database (2013) indicates that about 8 million people live in areas of active injection wells that have a greater than 1% chance of experiencing damaging ground shaking (MMI≥VI) in 2016. The final model has high uncertainty, and engineers, regulators, and industry should use these assessments cautiously to make informed decisions on mitigating the potential effects of induced and natural earthquakes.

This is the second part of a study that evaluates the influence of nonpoint sources on the sediment quality of five adjacent streams within the metropolitan Kansas City area, central United States. Physical, chemical, and toxicity data (Hyalella azteca 28-day whole-sediment toxicity test) for 29 samples collected in 2003 were used for this evaluation, and the potential causes for the toxic effects were explored. The sediments exhibited a low to moderate toxicity, with five samples identified as toxic to H. azteca. Metals did not likely cause the toxicity based on low concentrations of metals in the pore water and elevated concentrations of acid volatile sulfide in the sediments. Although individual polycyclic aromatic hydrocarbons (PAHs) frequently exceeded effect-based sediment quality guidelines [probable effect concentrations (PECs)], only four of the samples had a PEC quotient (PEC-Q) for total PAHs over 1.0 and only one of these four samples was identified as toxic. For the mean PEC-Q for organochlorine compounds (chlordane, dieldrin, sum DDEs), 4 of the 12 samples with a mean PEC-Q above 1.0 were toxic and 4 of the 8 samples with a mean PEC-Q above 3.0 were toxic. Additionally, four of eight samples were toxic, with a mean PEC-Q above 1.0 based on metals, PAHs, polychlorinated biphenyls (PCBs), and organochlorine pesticides. The increase in the incidence of toxicity with the increase in the mean PEC-Q based on organochlorine pesticides or based on metals, PAHs, PCBs, and organochlorine pesticides suggests that organochlorine pesticides might have contributed to the observed toxicity and that the use of a mean PEC-Q, rather than PEC-Qs for individual compounds, might be more informative in predicting toxic effects. Our study shows that stream sediments subject to predominant nonpoint sources contamination can be toxic and that many factors, including analysis of a full suite of PAHs and pesticides of both past and present urban applications and the origins of

Free water is considered important to wildlife in arid regions. In the western United States, thousands of water developments have been built to benefit wildlife in arid landscapes. Agencies and researchers have yet to clearly demonstrate their effectiveness. We combined a spatial analysis of summer chukar (Alectoris chukar) covey locations with dietary composition analysis in western Utah. Our specific objectives were to determine if chukars showed a spatial pattern that suggested association with free water in four study areas and to document summer dietary moisture content in relation to average distance from water. The observed data for the Cedar Mountains study area fell within the middle of the random mean distance to water distribution suggesting no association with free water. The observed mean distance to water for the other three areas was much closer than expected compared to a random spatial process, suggesting the importance of free water to these populations. Dietary moisture content of chukar food items from the Cedar Mountains (59%) was significantly greater (P model error components in future ecological research. ??

A generalization of the convex Kakeya problem

KAUST Repository

Ahn, Heekap

2013-09-19

Given a set of line segments in the plane, not necessarily finite, what is a convex region of smallest area that contains a translate of each input segment? This question can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be rotated through 360 degrees within this region. We show that there is always an optimal region that is a triangle, and we give an optimal Θ(nlogn)-time algorithm to compute such a triangle for a given set of n segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then placing the segments with their midpoint at the origin and taking their convex hull results in an optimal solution. Finally, we show that for any compact convex figure G, the smallest enclosing disk of G is a smallest-perimeter region containing a translate of every rotated copy of G. © 2013 Springer Science+Business Media New York.

Preliminary investigation Area 12 fleet operations steam cleaning discharge area Nevada Test Site

International Nuclear Information System (INIS)

1996-07-01

This report documents the characterization activities and findings of a former steam cleaning discharge area at the Nevada Test Site. The former steam cleaning site is located in Area 12 east of Fleet Operations Building 12-16. The characterization project was completed as a required condition of the ''Temporary Water Pollution Control Permit for the Discharge From Fleet Operations Steam Cleaning Facility'' issued by the Nevada Division of Environmental Protection. The project objective was to collect shallow soil samples in eight locations in the former surface discharge area. Based upon field observations, twelve locations were sampled on September 6, 1995 to better define the area of potential impact. Samples were collected from the surface to a depth of approximately 0.3 meters (one foot) below land surface. Discoloration of the surface soil was observed in the area of the discharge pipe and in localized areas in the natural drainage channel. The discoloration appeared to be consistent with the topographically low areas of the site. Hydrocarbon odors were noted in the areas of discoloration only. Samples collected were analyzed for bulk asbestos, Toxicity Characteristic Leaching Procedure (TCLP) metals, total petroleum hydrocarbons (TPHs), volatile organic compounds (VOCs), semi-volatile organic compounds (Semi-VOCs), and gamma scan
Do Quiet Areas Afford Greater Health-Related Quality of Life than Noisy Areas?

Full Text Available People typically choose to live in quiet areas in order to safeguard their health and wellbeing. However, the benefits of living in quiet areas are relatively understudied compared to the burdens associated with living in noisy areas. Additionally, research is increasingly focusing on the relationship between the human response to noise and measures of health and wellbeing, complementing traditional dose-response approaches, and further elucidating the impact of noise and health by incorporating human factors as mediators and moderators. To further explore the benefits of living in quiet areas, we compared the results of health-related quality of life (HRQOL questionnaire datasets collected from households in localities differentiated by their soundscapes and population density: noisy city, quiet city, quiet rural, and noisy rural. The dose-response relationships between noise annoyance and HRQOL measures indicated an inverse relationship between the two. Additionally, quiet areas were found to have higher mean HRQOL domain scores than noisy areas. This research further supports the protection of quiet locales and ongoing noise abatement in noisy areas.

Full Text Available Hasta la fecha se han desarrollado varios modelos experimentales para la reproducción experimental de la enfermedad meningocócica humana, cuya utilidad en la evaluación de la eficacia de medios de inmunización y terapia, así como en el estudio de la patogenia de la enfermedad es incuestionable. En el presente trabajo se describe la evaluación de la eficacia de VA-MENGOC-BC® y la Inmunoglobulina Humana Antimeningocócica BC frente a Neisseria meningitidis de los serogrupos A, B y C, empleando el ratón Balb/c tratado con mucina y dextrana férrica como estimulantes de la virulencia. Los ratones fueron inmunizados por vía intraperitoneal con una, dos o tres dosis de 0,5 mL de VA-MENGOC-BC®. El intervalo entre dosis fue de tres semanas entre la primera y segunda dosis y de 15 días entre la segunda y la tercera. El reto se realizó con dosis letales (1-3 x DL50 de N. meningitidis A, B ó C a los 15 ó 21 días después de aplicada la última dosis de vacuna. Para evaluar la actividad de la Inmunoglobulina Antimeningocócica BC como medio de inmunización pasiva, se trató otro grupo de ratones, 30 min, 2 y 6 h después habérseles inoculado los gérmenes. Se administraron en cada caso 5 mg de la inmunoglobulina por vía intraperitoneal o intravenosa en un volumen de 0,1 mL. Los resultados demostraron que tanto VA-MENGOC-BC® como la Globulina Antimeningocócica BC confieren protección significativa contra un reto letal con N. meningitidis en el modelo de ratón tratado con factores estimulantes de la virulencia.

Full Text Available Como resultado de observaciones llevadas a cabo durante los meses de enero a marzo de 1952, sobre varios aspectos de la enfermedad de Chagas en la región sudoccidental del Perú, se informa lo siguiente: 1. El Triatoma infestans es el único vector de la enfermedad de Chagas en la mencionada región. Su actual distribución abarcaría la vertiente occidental de los Andes desde el paralelo 14 al 18 de latitud sur, y desde el nivel del mar hasta las proximidades de los 3.500 me tros de altitud. 2. En la mayoría de las localidades el T. infestans se encuentra infectado por el Trypanosoma cruzi variando la incidencia de la infección de acuerdo con los animales domésticos sobre los cuales se alimenta el triatomino. Los lugares donde se crían o encierra cobayos siempre ofrecen mayor incidencia de la infección. 3. En busca de infecciones naturales al T. cruzi, por medio de observaciones de sangre fueron revisados 356 animales domésticos, entre los que se encuentran 297 cobayos, 32 perros, 14 conejos, 8 gatos y 5 cerdos. De éstos, en 17 cobayos y un gato fué posible verificar la infección. 4. En el valle de Moquegua se observó un caso de asociación entre el T. infestans y ratones grises, en las proximidades de una casa que parecía no se encontraba infestada por este triatomino. Tanto los triatomas como también los ratones capturados se encontraban infectados por el T. cruzi. 5. Finalmente se presentan algunas consideraciones sobre el rol de reservorio de la enfermedad de Chagas que desempeñarían ciertos animales domésticos en la región sudoccidental del Perú.

Numerous area-based initiatives have been implemented in deprived areas across Western-Europe with the aim to improve the socio-economic and environmental conditions in these areas. Only few of these initiatives have been scientifically evaluated for their impact on key social determinants of health, like perceived area safety. Therefore, this study aimed to assess the impact of a Dutch area-based initiative called the District Approach on trends in perceived area safety and underlying problems in deprived target districts. A quasi-experimental design was used. Repeated cross-sectional data on perceived area safety and underlying problems were obtained from the National Safety Monitor (2005-2008) and its successor the Integrated Safety Monitor (2008-2011). Study population consisted of 133,522 Dutch adults, including 3,595 adults from target districts. Multilevel logistic regression analyses were performed to assess trends in self-reported general safety, physical order, social order, and non-victimization before and after the start of the District Approach mid-2008. Trends in target districts were compared with trends in various control groups. Residents of target districts felt less safe, perceived less physical and social order, and were victimized more often than adults elsewhere in the Netherlands. For non-victimization, target districts showed a somewhat more positive change in trend after the start of the District Approach than the rest of the Netherlands or other deprived districts. Differences were only statistically significant in women, older adults, and lower educated adults. For general safety, physical order, and social order, there were no differences in trend change between target districts and control groups. Results suggest that the District Approach has been unable to improve perceptions of area safety and disorder in deprived areas, but that it did result in declining victimization rates.
Easy Leaf Area: Automated digital image analysis for rapid and accurate measurement of leaf area.

Measurement of leaf areas from digital photographs has traditionally required significant user input unless backgrounds are carefully masked. Easy Leaf Area was developed to batch process hundreds of Arabidopsis rosette images in minutes, removing background artifacts and saving results to a spreadsheet-ready CSV file. • Easy Leaf Area uses the color ratios of each pixel to distinguish leaves and calibration areas from their background and compares leaf pixel counts to a red calibration area to eliminate the need for camera distance calculations or manual ruler scale measurement that other software methods typically require. Leaf areas estimated by this software from images taken with a camera phone were more accurate than ImageJ estimates from flatbed scanner images. • Easy Leaf Area provides an easy-to-use method for rapid measurement of leaf area and nondestructive estimation of canopy area from digital images.

A probabilistic model employing a Monte Carlo sampling technique was developed in Python to generate statistical distributions of the upslope-intact-area to subsided-area ratio (Area_UAi/Area_SAi) for closure cap subsidence scenarios that differ in assumed percent subsidence and the total number of intact plus subsided compartments. The plan is to use this model as a component in the probabilistic system model for the E-Area Performance Assessment (PA), contributing uncertainty in infiltration estimates.

Blebs are cellular protrusions that are used by cells for multiple purposes including locomotion. A mechanical model for the problem of pressure-driven blebs based on force and moment balances of an axisymmetric shell model is proposed. The formation of a bleb is initiated by weakening the shell over a small region, and the deformation of the cellular membrane from the cortex is obtained during inflation. However, simply weakening the shell leads to an area increase of more than 4 %, which is physically unrealistic. Thus, the model is extended to include a reconfiguration process that allows large blebs to form with small increases in area. It is observed that both geometric and biomechanical constraints are important in this process. In particular, it is shown that although blebs are driven by a pressure difference across the cellular membrane, it is not the limiting factor in determining bleb size. © 2013 Springer-Verlag Berlin Heidelberg.

The third hans cloos lecture. Urban landslides: Socioeconomic impacts and overview of mitigative strategies

Science.gov (United States)

Schuster, R.L.; Highland, L.M.

2007-01-01

As a result of population pressures, hillsides in the world's urban areas are being developed at an accelerating rate. This development increases the risk for urban landslides triggered by rainfall or earthquake activity. To counter this risk, four approaches have been employed by landslide managers and urban planners: (1) restricting development in landslide-prone areas; (2) implementing and enforcing excavation, grading, and construction codes; (3) protecting existing developments by physical mitigation measures and (4) developing and installing monitoring and warning systems. Where they have been utilized, these approaches generally have been effective in reducing the risk due to landslide hazards. In addition to these practices, landslide insurance holds promise as a mitigative measure by reducing the financial impact of landslides on individual property owners. Until recently, however, such insurance has not been widely available and, where it is available, it is so expensive that it has been little used. ?? Springer-Verlag 2006.

Resource managers often face significant information technology (IT) problems when integrating ecological or environmental information to make decisions. At a workshop sponsored by the NSF and USGS in December 2004, university researchers, natural resource managers, and information managers met to articulate IT problems facing ecology and environmental decision makers. Decision making IT problems were identified in five areas: 1) policy, 2) data presentation, 3) data gaps, 4) tools, and 5) indicators. To alleviate those problems, workshop participants recommended specific informatics research in modeling and simulation, data quality, information integration and ontologies, and social and human aspects. This paper reports the workshop findings, and briefly compares these with research that traditionally falls under the emerging eco-informatics rubric. ?? Springer-Verlag Berlin Heidelberg 2005.

2014-07-01

Full Text Available Premise of the study: Measurement of leaf areas from digital photographs has traditionally required significant user input unless backgrounds are carefully masked. Easy Leaf Area was developed to batch process hundreds of Arabidopsis rosette images in minutes, removing background artifacts and saving results to a spreadsheet-ready CSV file. Methods and Results: Easy Leaf Area uses the color ratios of each pixel to distinguish leaves and calibration areas from their background and compares leaf pixel counts to a red calibration area to eliminate the need for camera distance calculations or manual ruler scale measurement that other software methods typically require. Leaf areas estimated by this software from images taken with a camera phone were more accurate than ImageJ estimates from flatbed scanner images. Conclusions: Easy Leaf Area provides an easy-to-use method for rapid measurement of leaf area and nondestructive estimation of canopy area from digital images.

300 Area Disturbance Report

LL Hale; MK Wright; NA Cadoret

1999-01-07

The objective of this study was to define areas of previous disturbance in the 300 Area of the U.S. Department of Energy (DOE) Hanford Site to eliminate these areas from the cultural resource review process, reduce cultural resource monitoring costs, and allow cultural resource specialists to focus on areas where subsurface disturbance is minimal or nonexistent. Research into available sources suggests that impacts from excavations have been significant wherever the following construction activities have occurred: building basements and pits, waste ponds, burial grounds, trenches, installation of subsurface pipelines, power poles, water hydrants, and well construction. Beyond the areas just mentioned, substrates in the' 300 Area consist of a complex, multidimen- sional mosaic composed of undisturbed stratigraphy, backfill, and disturbed sediments; Four Geographic Information System (GIS) maps were created to display known areas of disturbance in the 300 Area. These maps contain information gleaned from a variety of sources, but the primary sources include the Hanford GIS database system, engineer drawings, and historic maps. In addition to these maps, several assumptions can be made about areas of disturbance in the 300 Area as a result of this study: o o Buried pipelines are not always located where they are mapped. As a result, cultural resource monitors or specialists should not depend on maps depicting subsurface pipelines for accurate locations of previous disturbance. Temporary roads built in the early 1940s were placed on layers of sand and gravel 8 to 12 in. thick. Given this information, it is likely that substrates beneath these early roads are only minimally disturbed. Building foundations ranged from concrete slabs no more than 6 to 8 in. thick to deeply excavated pits and basements. Buildings constructed with slab foundations are more numerous than may be expected, and minimally disturbed substrates may be expected in these locations. Historic

Investigating scintillometer source areas

Science.gov (United States)

Perelet, A. O.; Ward, H. C.; Pardyjak, E.

2017-12-01

Scintillometry is an indirect ground-based method for measuring line-averaged surface heat and moisture fluxes on length scales of 0.5 - 10 km. These length scales are relevant to urban and other complex areas where setting up traditional instrumentation like eddy covariance is logistically difficult. In order to take full advantage of scintillometry, a better understanding of the flux source area is needed. The source area for a scintillometer is typically calculated as a convolution of point sources along the path. A weighting function is then applied along the path to compensate for a total signal contribution that is biased towards the center of the beam path, and decreasing near the beam ends. While this method of calculating the source area provides an estimate of the contribution of the total flux along the beam, there are still questions regarding the physical meaning of the weighted source area. These questions are addressed using data from an idealized experiment near the Salt Lake City International Airport in northern Utah, U.S.A. The site is a flat agricultural area consisting of two different land uses. This simple heterogeneity in the land use facilitates hypothesis testing related to source areas. Measurements were made with a two wavelength scintillometer system spanning 740 m along with three standard open-path infrared gas analyzer-based eddy-covariance stations along the beam path. This configuration allows for direct observations of fluxes along the beam and comparisons to the scintillometer average. The scintillometer system employed measures the refractive index structure parameter of air for two wavelengths of electromagnetic radiation, 880 μm and 1.86 cm to simultaneously estimate path-averaged heat and moisture fluxes, respectively. Meteorological structure parameters (CT2, Cq2, and CTq) as well as surface fluxes are compared for various amounts of source area overlap between eddy covariance and scintillometry. Additionally, surface

The posterior frontal lobe of the brain houses Brodmann area 4, which is the primary motor cortex, and Brodmann area 6, which consists of the supplementary motor area on the medial portion of the hemisphere and the premotor cortex on the lateral portion. In this area, safe resection is dependent on accurate localization of the motor cortex and the central sulcus, which can usually be achieved by using thin-section imaging and confirmed by using other techniques. The most reliable anatomic landmarks are the "hand knob" area and the marginal ramus of the cingulate sulcus. Postoperatively, motor deficits can occur not only because of injury to primary motor cortex but also because of injury to the supplementary motor area. Unlike motor cortex injury, the supplementary motor area syndrome is transient, if it occurs at all. On the lateral hemisphere, motor and language deficits can also occur because of premotor cortex injury, but a dense motor deficit would indicate subcortical injury to the corticospinal tract. The close relationship of the subcortical motor fibers and premotor cortex is illustrated. In contrast to the more constant landmarks of the central sulcus and marginal ramus, which aid in preoperative localization, the variable interruptions in the precentral and cingulate sulci of the posterior frontal lobe seem to provide "cortical bridges" for spread of infiltrating gliomas.

To date, numerous Jurassic hydrocarbon fields and pools have been discovered in the Cotton Valley Group, Haynesville Formation, Smackover Formation and Norphlet Formation in the tri-state area of Mississippi, Alabama and Florida, and in Alabama State coastal waters and adjacent Federal waters area. Petroleum traps are basement highs, salt anticlines, faulted salt anticlines and extensional faults associated with salt movement. Reservoirs include continental and marine sandstones, limestones and dolostones. Hydrocarbon types are oil, condensate and natural gas. The onshore stratigraphic and structural information can be used to establish a regional geologic framework for the Jurassic for the State coastal waters and adjacent Federal waters areas. Evaluation of the geologic information along with the hydrocarbon data from the tri-state area indicates that at least three Jurassic hydrocarbon trends (oil, oil and gas condensate, and deep natural gas) can be identified onshore. These onshore hydrocarbon trends can be projected into the Mobile area in the Central Gulf of Mexico and into the Pensacola, Destin Dome and Apalachicola areas in the Eastern Gulf of Mexico. Substantial reserves of natural gas are expected to be present in Alabama State waters and the northern portion of the Mobile area. Significant accumulations of oil and gas condensate may be encountered in the Pensacola, Destin Dome, and Apalachicola areas. ?? 1989.

The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL), under an interagency agreement with the Bureau of Ocean Energy Management (BOEM), is providing technical assistance to identify and delineate leasing areas for offshore wind energy development within the Atlantic Coast Wind Energy Areas (WEAs) established by BOEM. This report focuses on NREL's development of three delineated leasing area options for the Massachusetts (MA) WEA and the technical evaluation of these leasing areas. The overarching objective of this study is to develop a logical process by which the MA WEA can be subdivided into non-overlapping leasing areas for BOEM's use in developing an auction process in a renewable energy lease sale. NREL worked with BOEM to identify an appropriate number of leasing areas and proposed three delineation alternatives within the MA WEA based on the boundaries announced in May 2012. A primary output of the interagency agreement is this report, which documents the methodology, including key variables and assumptions, by which the leasing areas were identified and delineated.
2016 Waste Management Monitoring Report Area 3 and Area 5 Radioactive Waste Management Sites

Environmental monitoring data are collected at and around the Area 3 and Area 5 Radioactive Waste Management Sites (RWMSs) within the Nevada National Security Site (NNSS). These data include direct radiation exposure, as well as radiation from the air, groundwater, meteorology, and vadose zone. This report summarizes the 2016 environmental data to provide an overall evaluation of RWMS performance and to support environmental compliance and performance assessment (PA) activities. Some of these data (e.g., radiation exposure, air, and groundwater) are presented in other reports, developed by National Security Technologies, LLC Direct radiation monitoring data indicate exposure levels at the RWMSs are within the range of background levels measured at the NNSS. Slightly elevated exposure levels outside the Area 3 RWMS are attributed to nearby historical aboveground nuclear weapons tests. Air monitoring data show that tritium concentrations in water vapor and americium and plutonium concentrations in air particles are below Derived Concentration Standards for these radionuclides. Groundwater monitoring data indicate the groundwater in the uppermost aquifer beneath the Area 5 RWMS is not impacted by RWMS operations. Results of groundwater analysis from wells around the Area 5 RWMS were all below established investigation levels. Leachate samples collected from the leachate collection system at the mixed low-level waste cell were below established contaminant regulatory limits. During 2016, precipitation at the Area 3 RWMS was 8% below average, and precipitation at the Area 5 RWMS was 8% above average. Water balance measurements indicate that evapotranspiration from the vegetated weighing lysimeter dries the soil and prevents downward percolation of precipitation more effectively than evaporation as measured from the bare-soil weighing lysimeter. Vadose zone monitoring on Area 5 and Area 3 RWMS cell covers shows no evidence of precipitation percolating through the covers

Plutonium focus area

International Nuclear Information System (INIS)

1996-08-01

To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA). The following information outlines the scope and mission of the EM, EM-60, and EM-66 organizations as related to the PFA organizational structure

This report documents the history of the major buildings in Sandia National Laboratories` Technical Area II. It was prepared in support of the Department of Energy`s compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission`s integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area`s primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on high-explosive components outside of the original Area II diamond-shaped parcel. Most of the buildings in the area are vacant and Sandia has no plans to use them. They are proposed for decontamination and demolition as funding becomes available.

Full Text Available This study aimed to estimate the watershed runoff caused by extreme events that often result in the flooding of urban areas. The runoff of a residential area in the city of Guaratinguetá, São Paulo, Brazil was estimated using the Curve-Number method proposed by USDA-NRCS. The study also investigated current land use and land cover conditions, impermeable areas with pasture and indications of the reforestation of those areas. Maps and satellite images of Residential Riverside I Neighborhood were used to characterize the area. In addition to characterizing land use and land cover, the definition of the soil type infiltration capacity, the maximum local rainfall, and the type and quality of the drainage system were also investigated. The study showed that this neighborhood, developed in 1974, has an area of 792,700 m², a population of 1361 inhabitants, and a sloping area covered with degraded pasture (Guaratinguetá-Piagui Peak located in front of the residential area. The residential area is located in a flat area near the Paraiba do Sul River, and has a poor drainage system with concrete pipes, mostly 0.60 m in diameter, with several openings that capture water and sediments from the adjacent sloping area. The Low Impact Development (LID system appears to be a viable solution for this neighborhood drainage system. It can be concluded that the drainage system of the Guaratinguetá Riverside I Neighborhood has all of the conditions and characteristics that make it suitable for the implementation of a low impact urban drainage system. Reforestation of Guaratinguetá-Piagui Peak can reduce the basin’s runoff by 50% and minimize flooding problems in the Beira Rio neighborhood.

Tongyi Ma

2016-02-01

Full Text Available Abstract The L p $L_{p}$ -geominimal surface area was introduced by Lutwak in 1996, which extended the important concept of the geominimal surface area. Recently, Wang and Qi defined the p-dual geominimal surface area, which belongs to the dual Brunn-Minkowski theory. In this paper, based on the concept of the dual Orlicz mixed volume, we extend the dual geominimal surface area to the Orlicz version and give its properties. In addition, the isoperimetric inequality, a Blaschke-Santaló type inequality, and the monotonicity inequality for the dual Orlicz geominimal surface areas are established.

Natural Protected Areas and Rural/Local Development: A Sustainable Strategy in Remote Areas

Full Text Available The value and resources of the landscape and heritage of the Pyrenees, conserved in Natural Conservation Areas, have not been included in local social/economic development. The necessary policies and transverse working methods have not taken on board the benefits of these natural, protected areas on local, economic development. In some parts of the Pyrenees like Alt Urgell county the process of naturbanisation is just beginning. There is a great opportunity to put the brakes on uncontrolled urban development. At the same time, the potential to exploit the heritage and resources of the Pyrenees still exists. Therefore, the research defences that Natural Reserved Areas can act as a driving force to articulate a quality label of landscape, heritage and territory in peripheral areas like West Catalan Pyrenees. At the same time, by through promotion of Natural Reserved Areas a multi-organisational project of local development can be build. In the framework of rural-urban dynamics in a global context, the paper explains how the values of landscape and heritage in the mountain areas can be an opportunity to put into practice integrated territorial policies applying transversal methodologies among actors, institutions and private sector. At the same time, local development projects would priories young people and women support as one of the sector more likely to innovate and to maintain social and human capital in peripheral areas. A cooperation and collaboration practices are needed to create new economic activities with the participation of local actors. This paper puts forward suggestions for action to be taken.

In January 1994, the US Department of Energy Office of Environmental Management (DOE EM) formally introduced its new approach to managing DOE`s environmental research and technology development activities. The goal of the new approach is to conduct research and development in critical areas of interest to DOE, utilizing the best talent in the Department and in the national science community. To facilitate this solutions-oriented approach, the Office of Science and Technology (EM-50, formerly the Office of Technology Development) formed five Focus AReas to stimulate the required basic research, development, and demonstration efforts to seek new, innovative cleanup methods. In February 1995, EM-50 selected the DOE Morgantown Energy Technology Center (METC) to lead implementation of one of these Focus Areas: the Decontamination and Decommissioning (D & D) Focus Area.

As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico. As a result, Pueblo residents had become concerned that contaminants from Area G could enter tribal lands through various ecological pathways. The residents specifically questioned the safety of consuming meat from elk and deer that forage near Area G and then migrate onto tribal lands. Consequently, this study addresses the uptake of 3 H, 90 Sr, tot U, 238 Pu, 239 Pu, 241 Am, and 137 Cs by elk (Cervus elaphus) and deer (Odocoileus hemionus) that forage around the perimeter of Area G and the associated doses to the animals and to humans who consume these animals. Radionuclide uptake by and internal dose to animals was estimated using equations modified from National Council on Radiological Protection Report 76. The Residual Radiation computer code was used to estimate the external dose to animals and the dose to humans consuming meat. Soil and water concentrations from the perimeter of Area G and from background regions in northern New Mexico were averaged over 4 years (1993--1996) and used as input data for the models. Concentration estimates generated by the model correspond to the concentration range measured in actual tissue samples from elk and deer collected at LANL. The highest dose estimates for both animals (0.028 mrad/d) and humans (0.072 mrem/y) were well below

This report summarizes results of recent analyses of radioactivity in fish from SRS streams near the F-Area and H-Area seepage basins. Fish were collected from headwater areas of Four Mile Creek and Pen Branch, from just below the H-Area seepage basin, and from three sites downstream in Four Mile Creek. These fish were analyzed for gross alpha and gross beta radioactivity using standard EPA methods. Levels of gross alpha and nonvolatile beta radioactivity in fish were found to be comparable to levels previously reported for these sites. Gross alpha activity was not found to be influenced by Separations Area discharges. Nonvolatile beta activity was higher in the nonvolatile beta activity was attributable to Cs-137 and K-40. The dosimetric consequences of consuming fish from this area were found to be well below DOE guidelines

A computer simulation approach to quantify the true area and true area compressibility modulus of biological membranes

International Nuclear Information System (INIS)

Chacón, Enrique; Tarazona, Pedro; Bresme, Fernando

2015-01-01

We present a new computational approach to quantify the area per lipid and the area compressibility modulus of biological membranes. Our method relies on the analysis of the membrane fluctuations using our recently introduced coupled undulatory (CU) mode [Tarazona et al., J. Chem. Phys. 139, 094902 (2013)], which provides excellent estimates of the bending modulus of model membranes. Unlike the projected area, widely used in computer simulations of membranes, the CU area is thermodynamically consistent. This new area definition makes it possible to accurately estimate the area of the undulating bilayer, and the area per lipid, by excluding any contributions related to the phospholipid protrusions. We find that the area per phospholipid and the area compressibility modulus features a negligible dependence with system size, making possible their computation using truly small bilayers, involving a few hundred lipids. The area compressibility modulus obtained from the analysis of the CU area fluctuations is fully consistent with the Hooke’s law route. Unlike existing methods, our approach relies on a single simulation, and no a priori knowledge of the bending modulus is required. We illustrate our method by analyzing 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine bilayers using the coarse grained MARTINI force-field. The area per lipid and area compressibility modulus obtained with our method and the MARTINI forcefield are consistent with previous studies of these bilayers

The primary motor cortex is located in Brodmann area 4 at the most posterior part of the frontal lobe. The primary motor cortex corresponds to an output stage of motor signals, sending motor commands to the brain stem and spinal cord. Brodmann area 6 is rostral to Brodmann area 4, where multiple higher-order motor areas are located. The premotor area, which is located in the lateral part, is involved in planning and executing action based on sensory signals. The premotor area contributes to the reaching for and grasping of an object to achieve a behavioral goal. The supplementary motor area, which occupies the mesial aspect, is involved in planning and executing actions based on internalized or memorized signals. The supplementary motor area plays a central role in bimanual movements, organizing multiple movements, and switching from a routine to a controlled behavior. Thus, Brodmann areas 4 and 6 are considered as central motor areas in the cerebral cortex, in which the idea of an action is transformed to an actual movement in a variety of contexts.

According to the three notions of mixed affine surface area, Lp-affine surface area and Lp-mixed affine surface area proposed by Lutwak, in this article, we give the concept of ith Lp-mixed affine surface area such that the first and second notions of Lutwak are its special cases. Further, some Lutwak's results are extended associated with this concept. Besides, applying this concept, we establish an inequality for the volumes and dual quermassintegrals of a class of star bodies.

Hydrological characterization and moisture monitoring activities provide data required for evaluating the transport of subsurface contaminants in the unsaturated and saturated zones beneath Area G, and for the Area G Performance Assessment and Composite Analysis. These activities have been ongoing at Area G, Technical Area 54 of the Los Alamos National Laboratory since waste disposal operations began in 1957. This report summarizes the hydrological characterization and moisture monitoring activities conducted at Area G. It includes moisture monitoring data collected from 1986 through 2016 from numerous boreholes and access tubes with neutron moisture meters, as well as data collected by automated dataloggers for water content measurement sensors installed in a waste disposal pit cover, and buried beneath the floor of a waste disposal pit. This report is an update of a nearly identical report by Levitt et al., (2015) that summarized data collected through early 2015; this report includes additional moisture monitoring data collected at Pit 31 and the Pit 38 extension through December, 2016. It also includes information from the Jennings and French (2009) moisture monitoring report and includes all data from Jennings and French (2009) and the Draft 2010 Addendum moisture monitoring report (Jennings and French, 2010). For the 2015 version of this report, all neutron logging data, including neutron probe calibrations, were investigated for quality and pedigree. Some data were recalculated using more defensible calibration data. Therefore, some water content profiles are different from those in the Jennings and French (2009) report. All of that information is repeated in this report for completeness. Monitoring and characterization data generally indicate that some areas of the Area G vadose zone are consistent with undisturbed conditions, with water contents of less than five percent by volume in the top two layers of the Bandelier tuff at Area G. These data also

Marine protected areas (MPAs) are considered one of the main tools in both fisheries and conservation management to protect threatened species and their habitats around the globe. However, MPAs are underrepresented in marine environments compared to terrestrial environments. Within this context, we studied the Atlantic non-breeding distribution of the southern population of Balearic shearwaters (Puffinus mauretanicus) breeding in Eivissa during the 2011-2012 period based on global location sensing (GLS) devices. Our objectives were (1) to identify overall Important Atlantic Areas (IAAs) from a southern population, (2) to describe spatio-temporal patterns of oceanographic habitat use, and (3) to assess whether existing conservation areas (Natura 2000 sites and marine Important Bird Areas (IBAs)) cover the main IAAs of Balearic shearwaters. Our results highlighted that the Atlantic staging (from June to October in 2011) dynamic of the southern population was driven by individual segregation at both spatial and temporal scales. Individuals ranged in the North-East Atlantic over four main IAAs (Bay of Biscay: BoB, Western Iberian shelf: WIS, Gulf of Cadiz: GoC, West of Morocco: WoM). While most individuals spent more time on the WIS or in the GoC, a small number of birds visited IAAs at the extremes of their Atlantic distribution range (i.e., BoB and WoM). The chronology of the arrivals to the IAAs showed a latitudinal gradient with northern areas reached earlier during the Atlantic staging. The IAAs coincided with the most productive areas (higher chlorophyll a values) in the NE Atlantic between July and October. The spatial overlap between IAAs and conservation areas was higher for Natura 2000 sites than marine IBAs (areas with and without legal protection, respectively). Concerning the use of these areas, a slightly higher proportion of estimated positions fell within marine IBAs compared to designated Natura 2000 sites, with Spanish and Portuguese conservation
Annex D-200 Area Interim Storage Area Final Safety Analysis Report [FSAR] [Section 1 & 2

The 200 Area Interim Storage Area (200 Area ISA) at the Hanford Site provides for the interim storage of non-defense reactor spent nuclear fuel (SNF) housed in aboveground dry cask storage systems. The 200 Area ISA is a relatively simple facility consisting of a boundary fence with gates, perimeter lighting, and concrete and gravel pads on which to place the dry storage casks. The fence supports safeguards and security and establishes a radiation protection buffer zone. The 200 Area ISA is nominally 200,000 ft{sup 2} and is located west of the Canister Storage Building (CSB). Interim storage at the 200 Area ISA is intended for a period of up to 40 years until the materials are shipped off-site to a disposal facility. This Final Safety Analysis Report (FSAR) does not address removal from storage or shipment from the 200 Area ISA. Three different SNF types contained in three different dry cask storage systems are to be stored at the 200 Area ISA, as follows: (1) Fast Flux Test Facility Fuel--Fifty-three interim storage casks (ISC), each holding a core component container (CCC), will be used to store the Fast Flux Test Facility (FFTF) SNF currently in the 400 Area. (2) Neutron Radiography Facility (NRF) TRIGA'--One Rad-Vault' container will store two DOT-6M3 containers and six NRF TRIGA casks currently stored in the 400 Area. (3) Commercial Light Water Reactor Fuel--Six International Standards Organization (ISO) containers, each holding a NAC-I cask4 with an inner commercial light water reactor (LWR) canister, will be used for commercial LWR SNF from the 300 Area. An aboveground dry cask storage location is necessary for the spent fuel because the current storage facilities are being shut down and deactivated. The spent fuel is being transferred to interim storage because there is no permanent repository storage currently available.
On population growth near protected areas.

Directory of Open Access Journals (Sweden)

Lucas N Joppa

Full Text Available Protected areas are the first, and often only, line of defense in efforts to conserve biodiversity. They might be detrimental or beneficial to rural communities depending on how they alter economic opportunities and access to natural resources. As such, protected areas may attract or repel human settlement. Disproportionate increases in population growth near protected area boundaries may threaten their ability to conserve biodiversity.Using decadal population datasets, we analyze population growth across 45 countries and 304 protected areas. We find no evidence for population growth near protected areas to be greater than growth of rural areas in the same country. Furthermore, we argue that what growth does occur near protected areas likely results from a general expansion of nearby population centers.Our results contradict those from a recent study by Wittemyer et al., who claim overwhelming evidence for increased human population growth near protected areas. To understand the disagreement, we re-analyzed the protected areas in Wittemyer et al.'s paper. Their results are simply artifacts of mixing two incompatible datasets. Protected areas may experience unusual population pressures near their edges; indeed, individual case studies provide examples. There is no evidence, however, of a general pattern of disproportionate population growth near protected areas.
