Current target industry analysis: Las Vegas Metropolitan Area

International Nuclear Information System (INIS)

Boyle, M.R.

1988-06-01

This is the second of three reports dealing with the Las Vegas MSA's economic development potential in support of an overall effort to prepare an environmental impact statement for the proposed underground nuclear waste storage facility at Yucca Mountain. The first report provides an assessment of the MSA current business climate for economic growth. This second report draws on that business climate assessment to evaluate the Las Vegas MSA's competitive posture in pursuing business investment in the ''primary'' sector of the economy -- businesses which sell their products or services outside the local marketplace and bring new money back into the area and businesses serving local customers who would otherwise import these products or services from suppliers outside the area. GSO has developed an analytic tool which attempts to model the decision process used by businesses in selecting locations for new or expanded business investment. This computer based model reflects variations in site selection decision making among industries and ownership and management types. The underlying premise of the GSO locational compatibility index (LCI) model is that locational decisions are based more on a process of elimination that on a process of selection. There are many factors, some essential and some desirable, which influence any site selection decision. Multivariate comparative analyses narrow the geographic field to a region, then a group of states, then a state, then a sub-state region, then a community and finally to a specific site. Sometimes these analyses are rational and quantitative. More often, they are at least partially random and intuitive. 2 tabs

Lindsey A Harvell

2016-02-01

Full Text Available Purpose: This study examines how anxious the Las Vegas public is through a case study of one local international airport. Design/Methodology/Approach: This study examines gender differences in consumer behaviors among the flying public inside Las Vegas McCarran International Airport in a field experiment theoretically grounded in Terror Management Theory. Findings and Originality/Value: Because airports are replete with reminders of human mortality, it is not a surprise that death awareness and flight anxiety may be closely related. The flying public that is anxious to fly presents an interesting public relations situation for airports. Therefore, this study examines how anxious the Las Vegas public is through a case study of one local international airport. Results show that flight anxiety does provoke the same kind of existential defenses that traditional death awareness does. This study also suggests that men and women do not react to flight anxiety in a uniform way, they are different in their reactions in seeking to gamble, eating unhealthy food, and an increased desire for electronic entertainment.

Human-health pharmaceutical compounds in Lake Mead, Nevada and Arizona, and Las Vegas Wash, Nevada, October 2000-August 2001

Science.gov (United States)

Boyd, Robert A.; Furlong, Edward T.

2002-01-01

The U.S. Geological Survey and the National Park Service conducted a reconnaissance study to investigate the occurrence of selected human-health pharmaceutical compounds in water samples collected from Lake Mead on the Colorado River and Las Vegas Wash, a waterway used to transport treated wastewater from the Las Vegas metropolitan area to Lake Mead. Current research indicates many of these compounds can bioaccumulate and may adversely affect aquatic organisms by disrupting physiological processes, impairing reproductive functions, increasing cancer rates, contributing to the development of antibiotic-resistant strains of bacteria, and acting in undesirable ways when mixed with other substances. These compounds may be present in effluent because a high percentage of prescription and non-prescription drugs used for human-health purposes are excreted from the body as a mixture of parent compounds and degraded metabolite compounds; also, they can be released to the environment when unused products are discarded by way of toilets, sinks, and trash in landfills. Thirteen of 33 targeted compounds were detected in at least one water sample collected between October 2000 and August 2001. All concentrations were less than or equal to 0.20 micrograms per liter. The most frequently detected compounds in samples from Las Vegas Wash were caffeine, carbamazepine (used to treat epilepsy), cotinine (a metabolite of nicotine), and dehydronifedipine (a metabolite of the antianginal Procardia). Less frequently detected compounds in samples collected from Las Vegas Wash were antibiotics (clarithromycin, erythromycin, sulfamethoxazole, and trimethoprim), acetaminophen (an analgesic and anti-inflammatory), cimetidine (used to treat ulcers), codeine (a narcotic and analgesic), diltiazem (an antihypertensive), and 1,7-dimethylxanthine (a metabolite of caffeine). Fewer compounds were detected in samples collected from Lake Mead than from Las Vegas Wash. Caffeine was detected in all samples

Full Text Available RESUMEN Poco tiene que ver la edición original de 1972 de Learning from las Vegas, the forgotten symbolism of the architectural form, con la edición revisada de 1977, que fue traducida al español y publicada por Gustavo Gili en 1978. El gran formato del libro original (38x28cm se justificaba por la importancia del material gráfico desplegado, un ejercicio de análisis que aspiraba a descubrir nuevas técnicas de representación capaces de reproducir una realidad tan compleja sensorialmente como la de la ciudad de las Vegas. La drástica transformación, impulsada por los propios autores, suponía un abaratamiento y por tanto una mayor difusión del libro, pero sobretodo trataba de acabar con el conflicto entre su crítica al diseño Bauhaus y el diseño Bauhaus tardío del libro original, como señaló la propia Denise Scott Brown en el prologo de la edición revisada de 1977.

The Strip: Las Vegas and the Symbolic Destruction of Spectacle

OpenAIRE

Al, Stefan Johannes

2010-01-01

Over the past 70 years, various actors have dramatically reconfigured the Las Vegas Strip in many forms. I claim that behind the Strip's "reinventions" lies a process of symbolic destruction. Since resorts distinguish themselves symbolically, each new round of capital accumulation relies on the destruction of symbolic capital of existing resorts. A new resort either ups the language within a paradigm, or causes a paradigm shift, which devalues the previous resorts even further. This is why, i...

Hotel room suicide: Las Vegas and Clark County.

Gemar, Kjersti; Zarkowski, Paul; Avery, David

2008-01-01

Our objective is to study the link between hotel registration and suicide. Clark County, which contains Las Vegas, drew our interest because of its extremely large number of hotel rooms. Case files of suicide from the Clark County Coroner were reviewed for years 2003-2005. The suicide rate of local residents registering in local hotels was 271/100,000. This is greater than the suicide rate in the general population of Clark County, 16.6/100,000, PHotel guests from outside Clark County had a reduced rate of suicide, 4.6/100,000, Photels have an increased suicide risk that is statistically significant. Possible explanations for the results are provided.

Late quaternary environmental changes in the upper Las Vegas valley, Nevada

Science.gov (United States)

Quade, Jay

1986-11-01

Five stratigraphic units and five soils of late Pleistocene to Holocene age crop out in dissected badlands on Corn Creek Flat, 30 km northwest of Las Vegas, Nevada, and at Tule Springs, nearer to Las Vegas. The record is dominantly fluvial but contains evidence of several moister, marsh-forming periods: the oldest (Unit B) dates perhaps to the middle Wisconsin, and the more widespread Unit D falls between 30,000 and 15,000 yr B.P. Unit D therefore correlates with pluvial maximum lacustrine deposits elsewhere in the Great Basin. Standing water was not of sufficient depth or extent during either period to form lake strandlines. Between 14,000 and 7200 yr B.P. (Unit E), standing surface water gradually decreased, a trend also apparent in Great Basin pluvial lake chronologies during the same period. Groundwater carbonate cementation and burrowing by cicadas (Cicadae) accompany the moist-phase units. After 7200 yr B.P., increased wind action, decreased biotic activity, and at least 25 m of water-table lowering accompanied widespread erosion of older fine-grained deposits. Based on pack-rat midden and pollen evidence, this coincides with major vegetation changes in the valley, from sagebrush-dominated steppe to lower Mohave desertscrub.

Interferograms showing land subsidence and uplift in Las Vegas Valley, Nevada, 1992-99

Science.gov (United States)

Pavelko, Michael T.; Hoffmann, Jörn; Damar, Nancy A.

2006-01-01

The U.S. Geological Survey, in cooperation with the Nevada Department of Conservation and Natural Resources-Division of Water Resources and the Las Vegas Valley Water District, compiled 44 individual interferograms and 1 stacked interferogram comprising 29 satellite synthetic aperture radar acquisitions of Las Vegas Valley, Nevada, from 1992 to 1999. The interferograms, which depict short-term, seasonal, and long-term trends in land subsidence and uplift, are viewable with an interactive map. The interferograms show that land subsidence and uplift generally occur in localized areas, are responsive to ground-water pumpage and artificial recharge, and, in part, are fault controlled. Information from these interferograms can be used by water and land managers to mitigate land subsidence and associated damage. Land subsidence attributed to ground-water pumpage has been documented in Las Vegas Valley since the 1940s. Damage to roads, buildings, and other engineered structures has been associated with this land subsidence. Land uplift attributed to artificial recharge and reduced pumping has been documented since the 1990s. Measuring these land-surface changes with traditional benchmark and Global Positioning System surveys can be costly and time consuming, and results typically are spatially and temporally sparse. Interferograms are relatively inexpensive and provide temporal and spatial resolutions previously not achievable. The interferograms are viewable with an interactive map. Landsat images from 1993 and 2000 are viewable for frames of reference to locate areas of interest and help determine land use. A stacked interferogram for 1992-99 is viewable to visualize the cumulative vertical displacement for the period represented by the individual interferograms. The interactive map enables users to identify and estimate the magnitude of vertical displacement, visually analyze deformation trends, and view interferograms and Landsat images side by side. The

2007-05-01

Four photoacoustic spectrometers (PAS) for aerosol light scattering and absorption measurements were deployed in and near Mexico City in March 2006 as part of the Megacity Impacts on Regional and Global Environments (MIRAGE). The four sites included: an urban site at Instituto Mexicano del Petroleo (Mexican Oil Institute, denoted by IMP); a suburban site at the Technological University of Tecamac; a rural site at "La Biznaga" ranch; and a site at the Paseo de Cortes (altitude 3,810 meters ASL) in the rural area above Amecameca in the State of Mexico, on the saddle between the volcanoes Popocatepetl and Iztaccihuatl. A similar campaign was held in Las Vegas, Nevada, USA in January-February, 2003. The IMP site gave in-situ characterization of the Mexico City plume under favorable wind conditions while the other sites provided characterization of the plume, mixed in with any local sources. The second and third sites are north of Mexico City, and the fourth site is south. The PAS used at IMP operates at 532 nm, and conveniently allowed for characterization of gaseous absorption at this wavelength as well. Instruments at the second and third sites operate at 870 nm, and the one at the fourth site at 780 nm. Light scattering measurements are accomplished within the PAS by the reciprocal nephelometery method. In the urban site the aerosol absorption coefficient typically varies between 20 and 180 Mm-1 during the course of the day and significant diurnal variation of the aerosol single scattering albedo was observed probably as a consequence of secondary aerosol formation. Comparisons with TSI nephelometer scattering at the T0 site will be presented. We will present the diurnal variation of the scattering and absorption as well as the single scattering albedo and fraction of absorption due to gases at the IMP site and compare with Las Vegas diurnal variation.

Aerosol light scattering and absorption measurements were deployed in and near Mexico City in March 2006 as part of the Megacity Impacts on Regional and Global Environments (MIRAGE). The primary site in Mexico City was an urban site at Instituto Mexicano del Petroleo (Mexican Oil Institute, denoted by IMP). Similar campaigns were held in Las Vegas, NV in January-February, 2003; and Los Angeles, CA at numerous sites during all seasons from 2003 through 2007. The IMP site gave in-situ characterization of the Mexico City plume under favorable wind conditions. The photoacoustic instrument (PAS) used at IMP operates at 532 nm, and conveniently allowed for characterization of gaseous absorption at this wavelength as well. Light scattering measurements are accomplished within the PAS by the reciprocal nephelometery method. In Mexico City the aerosol absorption coefficient typically varies between 20 and 180 Mm-1 during the course of the day and significant diurnal variation of the aerosol single scattering albedo was observed probably as a consequence of secondary aerosol formation. We will present the diurnal variation of the scattering and absorption as well as the single scattering albedo and fraction of absorption due to gases at the IMP site and compare with Las Vegas diurnal variation. Mexico City 'breaths' more during the course of the day than Las Vegas, Nevada in part because the latitude of Mexico City resulted in more direct solar radiation. Further insight on the meteorological connections and population dynamics will be discussed.

Full Text Available The north-american trend called 'New Journalism' born in the 60's, was a revolution for the USA traditional Journalism, for its use of literary elements with other ones that belong to the journalistic research. Hunter S. Thompson, author of Fear and loathing in Las Vegas (1971, with his gonzo style, was going to shed new light on the New Journalism proposals, improving the immersión process using drugs until he gets implied personally in his reports and taking all his narrative influences from the 50's beat movement. Almost 35 years later, in El Dorado, Juan-Cantavella makes a paralellism between Las Vegas and the holiday city in the mediterranean coast, Marina D'Or and he develops in this space a novel, where his alter ego, the punk journalist Escargot, plays the lead. Novel, journalism, gonzo, fiction, story, punk, essay, report, 'aportaje', discursive fragmentation, dialogs, internal monologues, descriptions, memorandums, telegrams, emails, press releases, radio news, songs, slogans, all fits to reenact genres, to re-read journalistic and literary traditions and to build something new. This work analyses this process, that goes from the gonzo journalism of Fear and loathing in Las Vegas to the current Spanish narrative of El Dorado. It tries to distinguish the literary resources that the gonzo journalist uses to build his reports and the journalistic tools that nourish Juan-Cantavella's 'punk narrative'.

Sociohydrology of an Arid City: Development of a Coupled Model of Water Management in Las Vegas

Science.gov (United States)

Garcia, M. E.; Islam, S.; Portney, K. E.

2014-12-01

Rapidly growing cities in arid regions present a significant water management challenge. Key to tackling this challenge is understanding how and why some cities transition to more sustainable water management; acknowledging that urban water resources decisions are both responding to and precipitating hydrologic change, this question is best tackled through a sociohydrology approach. While coupling of natural and societal systems is in it's infancy in the field of hydrology, there is a strong tradition of studying coupled systems in the field of Socio-Ecological Systems. We build on Ostrom's Socio-Ecological Systems framework to develop a system dynamics model of water management for the Las Vegas metropolitan area using Vensim. A key objective our proposed modeling framework is to illuminate the dynamic interactions of the sociohydrologic system components and enable testing of various assumptions and strategies. The model of Las Vegas water management consists of five sub-modules: water supply, water demand, finances, public perception and policy making process. The development of the first three modules were based on clearly defined system structure. The public perception sub-module tracks the level public risk perception of a water supply shortage and represents the hypothesis that public risk perception is updated periodically when shortage events are experienced. The policy making process module uses an algorithm capturing the hypothesized decision making process to select policy actions (or in-action) from a set of feasible actions in response to the system states tracked by the model and observable to decision makers. The model was tested and parameterized using mix of quantitative data on water demands, supplies and costs and qualitative data from document analysis and interview data covering 1990 to 2010 period. Given that not only the parameters but also the structure of the public perception and the policy making process sub-systems is contested, a

As part of the Megacity Impacts on Regional and Global Environments, MIRAGE-Mex deployment to Mexico City in the period of 30 days, March 2006, a suite of photoacoustic spectrometers (PAS; W. Arnott & G. Paredes), nephelometer scattering, and aetholemeter absorption instruments (N. Marley & J.Gaffney) were installed to measure at ground level the light absorption and scattering by aerosols at the urban site at Instituto Mexicano del Petroleo (Mexican Oil Institute, denoted by IMP). This IMP site gave in-situ characterization of the Mexico City plume under favorable wind conditions. The PAS used at IMP operates at 532 nm, and conveniently allowed for characterization of gaseous absorption at this wavelength as well. Light scattering measurements are accomplished within the PAS by the reciprocal nephelometery method. In the urban site the aerosol absorption coefficient typically varies between 20 and 180 Mm-1 during the course of the day and significant diurnal variation of the aerosol single scattering albedo was observed. The Las Vegas, NV site was located at East Charleston Street on January-February, 2003. In east Las Vegas typical westerly winds carry the city plume across the site. Comparisons of PAS aerosol light absorption and aetholemeter absorption measurements at 521 nm at both Las Vegas NV and Mexico City sites will be presented. We will also present a broad overview of the diurnal variation of the scattering and absorption as well as the single scattering albedo and fraction of absorption due to gases at the sites in relation to secondary aerosol formation.

2010-10-01

Childhood exposure to environmental lead continues to be a major health concern. This study examined lead content within the plastic of children's toys collected from licensed day care centers in the Las Vegas valley, Nevada. It was hypothesized that the use of lead as a plastics stabilizer would result in elevated lead (≥600 ppm) in polyvinyl chloride plastics (PVC) compared to non-PVC plastics. It was also hypothesized that, due to the use of lead chromate as a coloring agent, yellow toys would contain higher concentrations of lead (≥600 ppm) than toys of other colors. Toy samples were limited to those found in day care centers in Las Vegas, Nevada. 10 day care centers were visited and approximately 50 toy samples were taken from each center. Of the 535 toys tested, 29 contained lead in excess of 600 parts per million (ppm). Of those 29 toys, 20 were PVC and 17 were yellow. Both of the two hypotheses were strongly supported by the data.

Evaluating Water Supply and Water Quality Management Options for Las Vegas Valley

Science.gov (United States)

Ahmad, S.

2007-05-01

The ever increasing population in Las Vegas is generating huge demand for water supply on one hand and need for infrastructure to collect and treat the wastewater on the other hand. Current plans to address water demand include importing water from Muddy and Virgin Rivers and northern counties, desalination of seawater with trade- payoff in California, water banking in Arizona and California, and more intense water conservation efforts in the Las Vegas Valley (LVV). Water and wastewater in the LVV are intrinsically related because treated wastewater effluent is returned back to Lake Mead, the drinking water source for the Valley, to get a return credit thereby augmenting Nevada's water allocation from the Colorado River. The return of treated wastewater however, is a major contributor of nutrients and other yet unregulated pollutants to Lake Mead. Parameters that influence the quantity of water include growth of permanent and transient population (i.e., tourists), indoor and outdoor water use, wastewater generation, wastewater reuse, water conservation, and return flow credits. The water quality of Lake Mead and the Colorado River is affected by the level of treatment of wastewater, urban runoff, groundwater seepage, and a few industrial inputs. We developed an integrated simulation model, using system dynamics modeling approach, to account for both water quantity and quality in the LVV. The model captures the interrelationships among many variables that influence both, water quantity and water quality. The model provides a valuable tool for understanding past, present and future pathways of water and its constituents in the LVV. The model is calibrated and validated using the available data on water quantity (flows at water and wastewater treatment facilities and return water credit flow rates) and water quality parameters (TDS and phosphorus concentrations). We used the model to explore important questions: a)What would be the effect of the water transported from

Full Text Available This article presents the latest results of the excavations at the site of Las Vegas in Huecas (Toledo. The site is located in an open area, near a stream and at the foot of the Valle de las Higueras necropolis. It is buried by a considerable colluvial deposition and was detected by geophysical survey. The site lacks structures and is made up of a single archaeological layer: it is a secondary deposit, containing Bell Beaker pottery and metal. A 14C sample has dated it to the second half of the 3rd millennium BC. Ceramics are the most abundant remain from this deposit. Macroscopic and X-ray Fluorescence (FRX analysis of the ceramics indicates a local production, the fast formation of this deposit, and its long-term exposure on the surface. We suggest that it was formed by cleaning and maintenance activities carried out in a nearby occupational area. We suggest that settlement occurred in the valley bottom, with occupations whose ceramic productions differ from the ones found in funerary contexts.Presentamos los resultados de los sondeos del yacimiento de Las Vegas, Huecas (Toledo.

Risk-induced social impacts: The effects of the proposed nuclear waste repository on residents of the Las Vegas metropolitan area

International Nuclear Information System (INIS)

Mushkatel, A.H.; Pijawka, K.D.; Dantico, M.

1990-09-01

This report examines important and major impacts of the proposed high-level nuclear waste repository on Las Vegas metropolitan residents. The data utilized in the report consist of interview data collected in the 1988, Urban Risk Survey and data for Clark County residents collected as part of the 1989 Nevada Telephone Survey. The use of two different data sets which were collected at two distinct points in time permit for not only determinations of the consistency of opinions and risk perceptions, but also result in a compelling consistency of findings demonstrating the types of impacts described in the report. The repository is viewed as an extremely dangerous facility where accidents are perceived as inevitable, and the consequences may result in catastrophic impacts. Over the last few years, the negative imagery of the repository, coupled with the view that the area may become stigmatized has amplified the perceived risks over the benefits. In addition, Las Vegas valley residents have little trust in the agencies empowered to ensure their safety and to mitigate the impacts from the facility. In this context it is difficult to believe that the federal agencies can regain much credibility among Clark County residents, or that the major impacts outlined in the report if the Yucca Mountain project becomes a reality will not come about. 20 refs., 3 figs., 36 tabs

Assessment of the impact of a nuclear waste repository at Yucca Mountain on the economic development potential of Las Vegas, Clark County, and the surrounding area

International Nuclear Information System (INIS)

Boyle, M.R.

1989-01-01

Growth Strategies Organization has completed an assessment of the Las Vegas MSA's competitiveness in the attraction of new business facilities to the area. That report found that under current business climate conditions and in the present economic development market place, the region is a competitive site for about one hundred of the six hundred types of primary businesses studied. It is almost competitive as a location for another 80 to 90 types of businesses and is a marginal choice for another 200 business groups. In other words, Clark County, as is, fully satisfies the basic requirements of almost a sixth of the businesses in this study. With minor improvements in areas such as the skill mix of its work force and the quality of its educational facilities and with an effective campaign to improve the area's image, the Las Vegas area could become a competitive location for about two-thirds of all business groups -- a very large shift in marketability. The proposed nuclear waste repository that he Federal government has proposed for siting at Yucca Mountain more than a hundred miles from Las Vegas would become operational after the turn of the century, more than fifteen years from now. Its influence on business investment decisions would be felt in the mid- to late-1990s if the final decision were made and announced. To measure that impact it would be desirable to establish a baseline that reflects Clark County's competitiveness as a business facility location in the middle of the next decade. In constructing that baseline, several variables could be considered -- changes in business climate conditions in the area other than the nuclear waste repository; and changes in the location decision process itself resulting from changes in technology and in market pressures

Full Text Available La Vega Central de Santiago de Chile. Un mercado reconocido por los santiaguinos como mercado popular compuesto por personas de distintos orígenes tanto sociales como étnicos. Para comprender la importancia de este sector comercial, es necesario hacer un recorrido histórico que muestre cuál es el origen de la Vega y cómo el lugar que ocupa le otorga un significado en el mundo popular para así entender los nuevos procesos emergentes relativos a la multiculturalidad. Desde la teoría de los No Lugares, se intenta entender cómo La Vega logra constituirse como un Lugar en la medida en que es habitado y construido por las personas, y como, a su vez, la temporalidad a la que es sometida logra generar un pliegue que transforma a este mercado en un No Lugar. Por lo tanto, la hipótesis que dirige este artículo tiene relación con que el horario de funcionamiento de La Vega permite el pliegue o la transformación entre este mercado como un Lugar y como un No Lugar. Abstract This paper focuses in a particular place, La Vega Central in Santiago de Chile. This is a marketplace known for santiaguinos as a people’s market, composed of people from different backgrounds, both social and ethnic. In order to understand the importance of this comercial sector, it is necesarry to do an historical overview showing La Vega’s origin and how the place gives it a meaning in the popular world. From the Non Place theory, we try to understand how La Vega does constitute a Place to the extent that it is inhabited and built by people, and how, in turn, the temporality to wich is subjected to achieves to generate a fold that transforms this market in a Non Place. Therefore, the hypothesis that runs this article is related to La Vega’s operating hours that allows the market’s transformation as a Place and a Non Place.

Effort-reward imbalance at work and self-rated health of Las Vegas hotel room cleaners.

Krause, Niklas; Rugulies, Reiner; Maslach, Christina

2010-04-01

This study investigates the relationship between effort-reward-imbalance (ERI) at work and self-rated health (SF-36) among 941 Las Vegas hotel room cleaners (99% female, 84% immigrant). Logistic regression models adjust for age, health behaviors, physical workload and other potential confounders. 50% reported ERI and 60% poor or fair general health. Significant associations were found between ERI and all SF-36 health measures. Workers in the upper quartile of the efforts/rewards ratio were 2-5 times more likely to experience poor or fair general health, low physical function, high levels of pain, fatigue, and role limitations due to physical and mental health problems. The cross-sectional design limits causal interpretation of these associations. However, the development of interventions to reduce ERI and to improve general health among room cleaners deserves high priority considering that both high ERI and low self-rated health have predicted chronic diseases and mortality in prospective studies.

1996-01-01

As part of early design studies for the potential Yucca Mountain nuclear waste repository, the authors have performed a preliminary probabilistic seismic hazard analysis of ground shaking. A total of 88 Quaternary faults within 100 km of the site were considered in the hazard analysis. They were characterized in terms of their probability o being seismogenic, and their geometry, maximum earthquake magnitude, recurrence model, and slip rate. Individual faults were characterized by maximum earthquakes that ranged from moment magnitude (M w ) 5.1 to 7.6. Fault slip rates ranged from a very low 0.00001 mm/yr to as much as 4 mm/yr. An areal source zone representing background earthquakes up to M w 6 1/4 = 1/4 was also included in the analysis. Recurrence for these background events was based on the 1904--1994 historical record, which contains events up to M w 5.6. Based on this analysis, the peak horizontal rock accelerations are 0.16, 0.21, 0.28, and 0.50 g for return periods of 500, 1,000, 2,000, and 10,000 years, respectively. In general, the dominant contributor to the ground shaking hazard at Yucca Mountain are background earthquakes because of the low slip rates of the Basin and Range faults. A significant effect on the probabilistic ground motions is due to the inclusion of a new attenuation relation developed specifically for earthquakes in extensional tectonic regimes. This relation gives significantly lower peak accelerations than five other predominantly California-based relations used in the analysis, possibly due to the lower stress drops of extensional earthquakes compared to California events. Because Las Vegas is located within the same tectonic regime as Yucca Mountain, the seismic sources and path and site factors affecting the seismic hazard at Yucca Mountain also have implications to Las Vegas. These implications are discussed in this paper

Water anomalies may reduce species abundance and diversity in alpine meadows as acidic and metal-rich waters are highly toxic to plants The study assessed the importance of surface water quality on plant abundance and diversity in high-alpine meadows at the Yerba Loca Natural Santuary (YLNS, central Chile (33°15' S, 70°18' W. Hydrochemical and plant prospecting were carried out on Piedra Carvajal, Chorrillos del Plomo and La Lata meadows the growing seasons of 2006 and 2007. Direct gradient analysis was performed through canonical correspondence analysis (CCA to look for relationships among water chemistry and plant factors. High variability in water chemistry was found inside and among meadows, particularly for pH, sulphate, electric conductivity, hardness, and total dissolved Cu, Zn, Cd, Pb and Fe. Data on species abundance and water chemical factors suggests that pH and total dissolved Cu are very important factor determining changes in plant abundance and diversity in study meadows. For instance, Festuca purpurascens, Colobanthus quitensis, and Arenaria rivularis are abundant in habitals with Cu-rich waters while Festuca magellanica, Patosia clandestina, Plantago barbata, Werneria pygmea, and Erigeron andícola are abundant in habitals with dilute waters.Los megadepósitos de pórfidos de Cu-Mo han influido sobre la calidad de las aguas superficiales en las zonas altoandinas del centro-norte de Chile desde el Mioceno.

We examined disparities in workers' occupational health experiences. We surveyed 941 unionized Las Vegas hotel room cleaners about their experiences with work-related pain and with employers, physicians, and workers' compensation. Data were analyzed for all workers and by ethnicity, language, and immigrant status. Hispanic and English as second language (ESL) workers were more likely than their counterparts to report work-related pain and, along with immigrant workers, to miss work because of this pain. Hispanic, ESL, and immigrant workers were not consistently at a disadvantage with regard to their own responses to work-related pain but were so with respect to reported responses by workers' compensation, physicians, and employers. There are indications of disparities in occupational health experiences within this job title. The use of different group classifications, while implying different mechanisms, produced similar results. © 2010 Wiley-Liss, Inc.

Milosevic, M.

1997-01-01

The VEGA is assembly spectrum code, developed as a design tool for producing a few-group averaged cross section data for a wide range of reactor types including both thermal and fast reactors. It belongs to a class of codes, which may be characterized by the separate stages for micro group, spectrum and macro group assembly calculations. The theoretical foundation for the development of the VEGA code was integral transport theory in the first-flight collision probability formulation. Two versions of VEGA are now in use, VEGA-1 established on standard equivalence theory and VEGA-2 based on new subgroup method applicable for any geometry for which a flux solution is possible. This paper describes a features which are unique to the VEGA codes with concentration on the basic principles and algorithms used in the proposed subgroup method. Presented validation of this method, comprise the results for a homogenous uranium-plutonium mixture and a PWR cell containing a recycled uranium-plutonium oxide. Example application for a realistic fuel dissolver benchmark problem , which was extensive analyzed in the international calculations, is also included. (author)

No primary data were gathered, nor were any formal surveys conducted. Additionally, because construction of a repository at Yucca Mountain, if that site is selected for a repository, is not scheduled to begin until 1993, engineering design and planned physical appearance of the repository are very preliminary. Therefore, specific design features or visual appearance were not addressed in the analyses.

Thane Hendricks

2008-01-01

As proficiency training for the Radiological Mapping mission of the Aerial Measuring System (AMS), a survey team from the Remote Sensing Laboratory-Nellis (RSL-Nellis) conducted aerial radiological surveys of the Las Vegas Strip and adjacent areas on December 11, 2006, and December 26 and 31, 2007. The AMS operation and appropriate law enforcement agencies selected the area as an appropriate urban location to exercise AMS capability for mapping environmental radiation and searching for man-made radioactive sources. The surveys covered ∼11 square miles. Each survey required a 2.5-hour-long flight, performed at an altitude of 300 ft above ground level (AGL) at a line spacing of 600 ft. Water line and test line flights were conducted over the Lake Mead and Government Wash areas to determine the nonterrestrial background contributed by aircraft, radon, and cosmic activity, and to determine the altitude-dependent air mass correction. The data were collected by the AMS data acquisition system (REDAR V) using an array of twelve 2-inch x 4-inch x 16-inch sodium iodide (NaI) detectors flown on-board a twin-engine Bell 412 helicopter. Gamma energy spectral data were collected second-by-second over the survey area. This spectral data allows the system to distinguish between natural terrestrial background contributions and man-made radioisotope contributions. Spectral data can also be used to identify specific man-made radioactive isotopes. Data geo-locations were determined with a Real-Time Differential Global Positioning System (RDGPS)

historia en el Inca Garcilaso de la Vega

Jorge Majfud

2007-01-01

Full Text Available Existen varios elementos ideológicos en la narración histórica del Inca Garcilaso de la Vega y una concepción de progreso de la historia que se opone a la más antigua de Hesíodo y de la Iglesia. En sus Comentarios Reales de los Incas procura una reivindicación de su pueblo original, en un contexto español; para ser aceptado, se propone no reescribir directamente la historia oficial, pero trastoca los significados de aquellos “hechos” narrados con anterioridad por los españoles en su Perú natal. Al mismo tiempo, realiza un mestizaje cosmológico que servirá como herramienta para confirmar su concepción de la historia y reivindicar, al mismo tiempo, sus orígenes étnicos y culturales. Pero, en gran medida, su perspectiva religiosa e intelectual ya pertenece a España. El Inca Garcilaso de la Vega no reconoce el panteísmo de los preincaicos y lo rechaza desde una perspectiva cristiana que separa al hombre de la naturaleza, lo que demuestra su concepción europea de la divinidad. Desprecia las culturas preincaicas porque adoraban lo inferior a ellos, mientras que los Incas –como los cristianos– adoraban lo superior y la unidad: el Sol. Más aún, Garcilaso de la Vega identifica, sin nombrarlo, al Sol con Dios y a Pachacámac con el Espíritu Santo. Jesu Christo será la culminación del progreso hacia la perfección de la Trinidad. La consecuencia es una concepción progresista de la historia que incluye a los incas y todos los pueblos (imperfectos que los precedieron. Pasa por encima del rito, del dogma y de las formas para encontrar en el pueblo inca un destino común a la civilización cristiana. Con ello también revela un componente humanista de una historia que se desarrolla con un objetivo universal y mestizo. No por casualidad, se nombra “Inca” con un apellido español, de la Vega, y lucha por conciliar ambas tradiciones: es un proyecto histórico, una voluntad de síntesis y una reivindicación personal.

A System Dynamics Modeling of Water Supply and Demand in Las Vegas Valley

Science.gov (United States)

Parajuli, R.; Kalra, A.; Mastino, L.; Velotta, M.; Ahmad, S.

2017-12-01

The rise in population and change in climate have posed the uncertainties in the balance between supply and demand of water. The current study deals with the water management issues in Las Vegas Valley (LVV) using Stella, a system dynamics modeling software, to model the feedback based relationship between supply and demand parameters. Population parameters were obtained from Center for Business and Economic Research while historical water demand and conservation practices were modeled as per the information provided by local authorities. The water surface elevation of Lake Mead, which is the prime source of water supply to the region, was modeled as the supply side whereas the water demand in LVV was modeled as the demand side. The study was done from the period of 1989 to 2049 with 1989 to 2012 as the historical one and the period from 2013 to 2049 as the future period. This study utilizes Coupled Model Intercomparison Project data sets (2013-2049) (CMIP3&5) to model different future climatic scenarios. The model simulates the past dynamics of supply and demand, and then forecasts the future water budget for the forecasted future population and future climatic conditions. The results can be utilized by the water authorities in understanding the future water status and hence plan suitable conservation policies to allocate future water budget and achieve sustainable water management.

Full Text Available Ambient non-refractory PM₁ aerosol particles were measured with an Aerodyne High Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-AMS at an elementary school 18 m from the US 95 freeway soundwall in Las Vegas, Nevada, during January 2008. Additional collocated continuous measurements of black carbon (BC, carbon monoxide (CO, nitrogen oxides (NO_x, and meteorological data were collected. The US~Environmental Protection Agency's (EPA positive matrix factorization (PMF data analysis tool was used to apportion organic matter (OM as measured by HR-AMS, and rotational tools in EPA PMF were used to better characterize the solution space and pull resolved factors toward known source profiles. Three- to six-factor solutions were resolved. The four-factor solution was the most interpretable, with the typical AMS PMF factors of hydrocarbon-like organic aerosol (HOA, low-volatility oxygenated organic aerosol (LV-OOA, biomass burning organic aerosol (BBOA, and semi-volatile oxygenated organic aerosol (SV-OOA. When the measurement site was downwind of the freeway, HOA composed about half the OM, with SV-OOA and LV-OOA accounting for the rest. Attempts to pull the PMF factor profiles toward source profiles were successful but did not qualitatively change the results, indicating that these factors are very stable. Oblique edges were present in G-space plots, suggesting that the obtained rotation may not be the most plausible one. Since solutions found by pulling the profiles or using F_peak retained these oblique edges, there appears to be little rotational freedom in the base solution. On average, HOA made up 26% of the OM, while LV-OOA was highest in the afternoon and accounted for 26% of the OM. BBOA occurred in the evening hours, was predominantly from the residential area to the north, and on average constituted 12% of the OM; SV-OOA accounted for the remaining third of the OM.

Understanding Transitions Toward Sustainable Urban Water Management: Miami, Las Vegas, Los Angeles

Science.gov (United States)

Garcia, M. E.; Manago, K. F.; Treuer, G.; Deslatte, A.; Koebele, E.; Ernst, K.

2016-12-01

Cities in the United States face numerous threats to their long-term water supplies including preserving ecosystems, competing uses, and climate change. Yet, it is unclear why only some cities have transitioned toward more sustainable water management. These transitions include strategies such as water conservation, water supply portfolio diversification, long-term planning, and integrated resource management. While the circumstances that motivate or moderate transition may vary greatly across cities' physical and institutional contexts, identifying common factors associated with transition can help resource managers capitalize on windows of opportunity for change. To begin the process of identifying such factors, we ask two questions: 1) what combinations of conditions are associated with water management transitions?, and 2) what are the outcomes of these transitions? We examine three cases of utility-level water management in Miami, Las Vegas, and Los Angeles to create data-driven narratives detailing each city's transition. These narratives systematically synthesize multiple data sources to enable cross-case comparison and provide insights into how and why cities transition. Using the foundational concepts from the exposure-based theory of urban change, we focus our analysis on three broad categories of variables that influence urban water management transition: biophysical, political, and regulatory exposures. First, we compare these factors across time and across cities using metrics that standardize diverse data sources. Next, we incorporate qualitative factors that capture a city's unique conditions by integrating these metrics with salient contextual information. Then, through cross-city comparison, we identify factors associated with transition.

Vega-Lite: A Grammar of Interactive Graphics.

Science.gov (United States)

Satyanarayan, Arvind; Moritz, Dominik; Wongsuphasawat, Kanit; Heer, Jeffrey

2017-01-01

We present Vega-Lite, a high-level grammar that enables rapid specification of interactive data visualizations. Vega-Lite combines a traditional grammar of graphics, providing visual encoding rules and a composition algebra for layered and multi-view displays, with a novel grammar of interaction. Users specify interactive semantics by composing selections. In Vega-Lite, a selection is an abstraction that defines input event processing, points of interest, and a predicate function for inclusion testing. Selections parameterize visual encodings by serving as input data, defining scale extents, or by driving conditional logic. The Vega-Lite compiler automatically synthesizes requisite data flow and event handling logic, which users can override for further customization. In contrast to existing reactive specifications, Vega-Lite selections decompose an interaction design into concise, enumerable semantic units. We evaluate Vega-Lite through a range of examples, demonstrating succinct specification of both customized interaction methods and common techniques such as panning, zooming, and linked selection.

RSL-Nellis Analysis of Radiological Data from the Las Vegas Motor Speedway

International Nuclear Information System (INIS)

Wasiolek, Piotr; Okada, Colin

2009-01-01

The Department of Energy (DOE) National Nuclear Security Administration (NNSA) is responsible for maintaining national-level radiological emergency response assets and for deploying those assets in the event of a radiological accident or incident. NNSA's emergency response assets include the Aerial Measuring System (AMS) and Search Response Team (SRT) operated by the Remote Sensing Laboratory (RSL) located at Nellis Air Force Base, Las Vegas, Nevada and Andrews Air Force Base in Suitland, Maryland. The AMS mission is to provide a rapid response to radiological emergencies with helicopters and fixed-wing aircraft equipped to detect and measure radioactive material on the ground. The acquired data are stored and used to produce maps of radiation exposure and activity concentration per unit area. AMS also conducts surveys to create radiological baselines of major cities and nuclear facilities throughout the country. The SRT's Crisis Response (CR) mission is to provide scientific, technical, and operational support for NNSA-directed search activities involving radiological search and identification, through both field deployments and home team and reachback support. The AMS radiological mapping and SRT CR emergency response teams from the Remote Sensing Laboratory-Nellis (RSL-N) supported safety and security activities at a NASCAR race at the Las Vegas Motor Speedway (LVMS) on February 27-March 1, 2009. In support of this event, and for proficiency training, these teams carried out aerial and ground surveys of the area. The aerial radiological survey of the LVMS was conducted on February 17, 2009, and the CR ground survey was performed on February 23, 2009. RSL-N operations and appropriate law enforcement agencies selected this area as a suitable location to exercise AMS and CR capabilities for mapping environmental radiation and searching for man-made radioactive sources. The aerial surveys covered approximately 11 square miles. The survey required a 2.5-hour flight

Hendricks, Thane; Reed, Michael

2008-01-01

As proficiency training for the Remote Sensing Laboratory's (RSL) Aerial Measuring System (AMS) radiological mapping mission, a survey team from RSL-Nellis conducted aerial radiological surveys of the Las Vegas Strip and adjacent areas on four separate occasions. The dates of the surveys were: December 11, 2006; December 26, 2007; December 31, 2007; and July 1, 2008. The AMS operation and appropriate law enforcement agencies selected the survey area as an appropriate urban location in which to exercise the AMS capability for mapping environmental radiation and searching for man-made radioactive sources. The surveys covered approximately 11 square miles. Each survey required a 2.5 hour-long flight, performed at an altitude of 300 ft above ground level (AGL), at a line spacing of 600 ft. Water line and test line flights were conducted over the Lake Mead and Government Wash areas in order to quantify the non-terrestrial background contributed by the aircraft, radon, and cosmic activity, and in order to determine the altitude-dependent air mass correction. The gamma data was collected by the AMS data acquisition system (REDAR V) using an array of twelve 2-inch x 4-inch x 16-inch sodium iodide (NaI) detectors flown on-board a twin-engine Bell 412 helicopter. One second gamma-energy spectral data were recorded continuously while in flight. This spectral data allows the system to distinguish between natural terrestrial background contributions and man-made radioisotope contributions. Spectral data can also be used to identify specific man-made radioactive isotopes. Data geo-locations were determined with a Real-Time Differential Global Positioning System (RDGPS). For the surveys occurring on December 26, 2007, and December 31, 2007, a neutron detection system was also flown. The neutron system consists of an array of eight moderated helium tubes, each cylindrical in nature measuring 6-feet in length with a diameter of 2-inches

Site Response in Las Vegas Valley, Nevada from NTS Explosions and Earthquake Data

Rodgers, Arthur; Tkalcic, Hrvoje; McCallen, David; Larsen, Shawn; Snelson, Catherine

2006-01-01

We report site response in Las Vegas Valley (LVV) from historical recordings of Nevada Test Site (NTS) nuclear explosions and earthquake recordings from permanent and temporary seismic stations. Our data set significantly improves the spatial coverage of LVV over previous studies, especially in the northern, deeper parts of the basin. Site response at stations in LVV was measured for frequencies in the range 0.2 5.0 Hz using Standard Spectral Ratios (SSR) and Horizontal-Vertical Spectral Ratios (HVR). For the SSR measurements we used a reference site (approximately NEHRP B ``rock'' classification) located on Frenchman Mountain outside the basin. Site response at sedimentary sites is variable in LVV with average amplifications approaching a factor of 10 at some frequencies. We observed peaks in the site response curves at frequencies clustered near 0.6, 1.2 and 2.0 Hz, with some sites showing additional lower amplitude peaks at higher frequencies. The spatial pattern of site response is strongly correlated with the reported depth to basement for frequencies between 0.2 and 3.0 Hz, although the frequency of peak amplification does not show a similar correlation. For a few sites where we have geotechnical shear velocities, the amplification shows a correlation with the average upper 30-meter shear velocities, V 30. We performed two-dimensional finite difference simulations and reproduced the observed peak site amplifications at 0.6 and 1.2 Hz with a low velocity near-surface layer with shear velocities 600 750 m/s and a thickness of 100 200 m. These modeling results indicate that the amplitude and frequencies of site response peaks in LVV are strongly controlled by shallow velocity structure.

The University of Nevada, Las Vegas (UNLV) established an Advanced Accelerator Applications (AAA) University Participation Program in March 2001 to develop a world-class research program for accelerator-driven transmutation technology while building core competencies and facilities to promote the University's strategic growth goals. The goal of this program is to involve UNLV students in research on the cutting edge of science and engineering as an integrated part of the national program to develop this emerging technology. This program augments UNLV's research capabilities and infrastructure, while establishing national and international research collaborations with national laboratories, industrial partners, and other universities, increasing the UNL V research community's presence in the global scientific community. The UNL V Program is closely integrated into the national project led by Los Alamos and Argonne National Laboratories. The primary mechanism to insure this degree of integration is the teaming of national laboratory scientists with UNL V faculty and students on student research proposals. The Program was implemented under an aggressive schedule with faculty response that surpassed expectations. A total of 12 multi-tasked projects that involve 21 graduate students and 13 faculty members began under first year funding. Other major accomplishments include establishment of an administrative structure implementing all the components of the Program and establishment of a communications network between national laboratory project leaders and UNL V faculty.

Surface and Airborne Arsenic Concentrations in a Recreational Site near Las Vegas, Nevada, USA

Science.gov (United States)

Goossens, Dirk

2015-01-01

Elevated concentrations of arsenic, up to 7058 μg g-1 in topsoil and bedrock, and more than 0.03 μg m-3 in air on a 2-week basis, were measured in the Nellis Dunes Recreation Area (NDRA), a very popular off-road area near Las Vegas, Nevada, USA. The elevated arsenic concentrations in the topsoil and bedrock are correlated to outcrops of yellow sandstone belonging to the Muddy Creek Formation (≈ 10 to 4 Ma) and to faults crossing the area. Mineralized fluids moved to the surface through the faults and deposited the arsenic. A technique was developed to calculate airborne arsenic concentrations from the arsenic content in the topsoil. The technique was tested by comparing calculated with measured concentrations at 34 locations in the NDRA, for 3 periods of 2 weeks each. We then applied it to calculate airborne arsenic concentrations for more than 500 locations all over the NDRA. The highest airborne arsenic concentrations occur over sand dunes and other zones with a surficial layer of aeolian sand. Ironically these areas show the lowest levels of arsenic in the topsoil. However, they are highly susceptible to wind erosion and emit very large amounts of sand and dust during episodes of strong winds, thereby also emitting much arsenic. Elsewhere in the NDRA, in areas not or only very slightly affected by wind erosion, airborne arsenic levels equal the background level for airborne arsenic in the USA, approximately 0.0004 μg m-3. The results of this study are important because the NDRA is visited by more than 300,000 people annually. PMID:25897667

Abundance of boron in Vega and Sirius

Praderie, F.; Boesgaard, A.M.; Milliard, B.; Pitois, M.L.

1977-01-01

High-resolution (0.05 A) observations of the region of the B II resonance line (1362 A) have been made of Vega (AO V) and Sirius (Al V) with the Copernicus satellite. A strong B II feature is present in Vega, but only a weak line, due primarily to V III, is present is Sirius. An upper limit of B/H -12 is derived for Sirius from line-profile fitting. A local thermodynamic equilibrium (LTE) synthesis of the B II blend in Vega results in an abundance ratio B/H=1 x 10 -10 . Calculations of the effects of non--LTE on the line profile show that the LTE abundance would not be increased by more than 50% (B.H=1.5 x 10 -10 ) to account for departures from LTE. The B content of Vega probably represents the cosmic B abundance. The B deficiency in Sirius could result from interaction with the white-dwarf companion at an earlier stage in its evolution or from diffusion processes in the Sirius atmosphere.Difficult observations at 0.10 A resolution of subordinate lines from multiplet (3) of B II at 1624 A show that those lines are not present in Sirius; but the identification of B in Vega appears to be confirmed by the presence of weak lines at 1624 A in this star

Little is known of the impact of the work environment on smoking among women holding low-paid jobs in the service sector. To study the associations between the components of the demand-control model with smoking in hotel room cleaners. We conducted a survey on work and health among 776 female hotel room cleaners in Las Vegas. Associations between psychosocial work characteristics and smoking were analyzed with multivariate regression analyses. Psychosocial work characteristics were associated with smoking after adjustment for covariates. Effect estimates were substantially reduced by additional adjustment for ethnicity, but remained significant for high psychological demands and smoking prevalence (OR = 1.97, p = 0.02), high job strain and smoking prevalence (OR = 1.87, p = 0.04), and high job strain and smoking intensity (coefficient = 3.52, p = 0.03). When analyses were restricted to Hispanic workers and further adjusted for place of birth, low decision latitude (coefficient = 3.94, p = 0.04) and high job strain (coefficient = 4.57, p = 003) were associated with smoking intensity but not with smoking status. Workplace smoking cessation programs may benefit from a primary prevention component reducing job strain among service workers. More research is needed on perceived and objective differences in psychosocial work characteristics across ethnic, immigrant, and other social groups within the same occupation.

Full Text Available Two cassiterite anomalies have been detected in the Regato de los Lentiscos and Tirados de la Vega alluviums. in the Golpejas area (Salamanca. The granometric and morphometric parameters of these cassiterites have been compared with those shown by the cassiterite crystal ocurrying in the Golpejas granite. The comparison between the two groups of data allow us to conclude that the anomaly observed in the Regato de los Lentiscos has been originated by the disperssion of the cassiterite from the primary deposit of Golpejas. On the contrary. the anomaly ocuring in the alluviums to the south of Tirados de la Vega shows a different origin, and is coming from stanniferous veins. The factor analysis corroborates the differentiation mentionated aboye. and indicates a migration capacite of about 3 Kms. from the stanniferous deposits of Golpejas for the alluvial cassiterite.En el sector Tirados de la Vega-Golpejas han sido detectadas dos anomalías de casiterita en los aluviones del Regato de los Lentiscos y en otros existentes al sur de Tirados de la Vega. El estudio granométrico y morfométrico de éstas casiteritas. contrastado con el de la casiterita procedente del granito de Golpejas. permite asegurar que la anomalía del Regato de los Lentiscos se debe a la dispersión de la casiterita de aquel granito. mientras que la de Tirados de la Vega procede de filones estanníferos. La aplicación del análisis factoral corrobora este hecho y permite diferenciar las casiteritas que proceden de rocas graníticas de aquellas que vienen de filones estanníferos. Según esto se puede indicar que la capacidad de migración de la casiterita desde el yacimiento estannífero de Golpejas es de unos 3 Kms.

His doctrine, mainly with regard to the morbus lateralis, supports the proper one from the most of the sixteenth century authors belonging to the medical humanism: a copious bloodletting in the elbow`s flexure of the homolateral arm. In addition to the Vesalius’ anatomical contributions on the venous tree recorded in that chapter, Vega has a debate on certain controversial aspects with the contemporary doctors Argenterio and Fuchs. In spite of his fidelity to the galenism, Vega shows some practical disagreements concerning its use in children, pregnant women and its achievement up to fainting.

Su doctrina, sobre todo en lo que atañe al morbus lateralis, sigue la de la mayoría de los autores del quinientos pertenecientes al humanismo médico: sangría abundante en la flexura del codo del brazo homolateral. Además de recoger las aportaciones anatómicas de Vesalio sobre el árbol venoso, Vega polemiza sobre ciertos aspectos controvertidos con los médicos coetáneos Argenterio y Fuchs. A pesar de su fidelidad al galenismo, Vega muestra algunas discrepancias prácticas relativas a su uso en niños y embarazadas y a su aplicación hasta el desvanecimiento.

Context. Although debris discs have been detected around a significant number of main-sequence stars, only a few of them are known to harbour hot dust in their inner part where terrestrial planets may have formed. Thanks to infrared interferometric observations, it is possible to obtain a direct measurement of these regions, which are of prime importance for preparing future exo-Earth characterisation missions. Aims: We resolve the exozodiacal dust disc around Vega with the help of infrared stellar interferometry and estimate the integrated H-band flux originating from the first few AUs of the debris disc. Methods: Precise H-band interferometric measurements were obtained on Vega with the 3-telescope IOTA/IONIC interferometer (Mount Hopkins, Arizona). Thorough modelling of both interferometric data (squared visibility and closure phase) and spectral energy distribution was performed to constrain the nature of the near-infrared excess emission. Results: Resolved circumstellar emission within ~6 AU from Vega is identified at the 3-σ level. The most straightforward scenario consists in a compact dust disc producing a thermal emission that is largely dominated by small grains located between 0.1 and 0.3 AU from Vega and accounting for 1.23 ± 0.45% of the near-infrared stellar flux for our best-fit model. This flux ratio is shown to vary slightly with the geometry of the model used to fit our interferometric data (variations within ± 0.19%). Conclusions: The presence of hot exozodiacal dust in the vicinity of Vega, initially revealed by K-band CHARA/FLUOR observations, is confirmed by our H-band IOTA/IONIC measurements. Whereas the origin of the dust is still uncertain, its presence and the possible connection with the outer disc suggest that the Vega system is currently undergoing major dynamical perturbations.

Preliminary results of the Halley comet investigation using the Vega-1 and Vega-2 space probes which passed on the 6th and 9th of March, 1986 the comet nucleus at a distance of 9000 and 8200 respectively, are presented. The comet nucleus appeared to be one of the darkest bodies of the Solar system: its albedo is just about 4%. The IR spectrum analysis has shown, that water and carbon dioxide appear to be the main components of the comet material. Mass analysis points out to the presence in the comet dust of iron, oxygen and silicon. It is ascertained, that about 30 t of water vapors and about 5-10 t of dust are evaporated from the comet nucleus surface in one second. Solar wind interaction with the comet streched atmosphere was investigated

En este sentido se discutirán las trayectorias de los mencionados autores para llevar a cabo el análisis comparado de sus vidas, sus ideologías y sus obras.This paper analyses the representation of colonial domination, process commonly known as "The Conquest", in the work of two writers belonging to the first half-breed generations of the early 17th century: Garcilaso de la Vega and Ruy Díaz de Guzmán. The selection is based on two fundamental criteria: on the one hand both declare themselves as "naturales" and reveal a strong sense of belonging regarding the cultural areas they describe; on the other hand, both attach themselves to opposite ethnic identities, thus maintaining a different relationship with the complex problems of mestizaje and miscegenation -while Garcilaso claims to be an Inca, Ruy Díaz de Guzmán introduces himself as a Spaniard. Therefore, the biographies of both authors are discussed in order to understand their life trajectories, ideologies and work from a comparative point of view.

Privatizing Water in the Chilean Andes: The Case of Las Vegas de Chiu-Chiu

Directory of Open Access Journals (Sweden)

Manuel Prieto

2015-08-01

Full Text Available The Chilean water model has been described as a textbook example of a free-market water system. This article contributes to the critiques of this model by showing the effect of its implementation in the Atacameño community of Chiu-Chiu, located in the Atacama Desert in the south-central Andes. In this community, the privatization of water rights ignored local water management practices that had produced a high-altitude wetland (known as a vega. This led to the inhabitants’ dispossession of crucial water rights and to wetland degradation. This process belies statements that the Chilean model relies on an unregulated market and instead highlights the state’s role in marginalizing local irrigation practices by reducing the water consumption of the indigenous population while keeping the copper mining industry (the main source of Chilean income and related growing urban populations supplied with water.

A comparison of greenhouse gas emissions and local area pollution of highspeed rail and air travel between Los Angeles and Las Vegas

Science.gov (United States)

Mullins, Damien

Global warming is one of the most discussed global environmental issues in the world today. Global warming is driven by fossil fuel combustion emissions known as Green-house Gases (GHG). One of the major contributors to GHG emissions is the transport sector, emitting approximately 30% of total U.S. CO 2 emissions in 2010. Air travel contributed approximately 3.5% of total U.S. CO2 in 2008. High-speed Rail (HSR) is often touted as cleaner, more sustainable mode of transport than air travel. HSR is one of few modes of transport capable of competing with air travel for short to medium-haul distances. There has been considerable study of GHG emissions of each independently. Research has also been carried out into the economics and competition of these transport modes. However, there has been very limited study of the comparative emissions of each, apart from one study in Europe (Givoni, 2007). The current study was undertaken with the goal of quantifying potential emission savings due to mode substitution from air travel to HSR in the Los Angeles to Las Vegas corridor. This study only considered the emissions which occurred from the combustion of the relevant fuels, either in power plants or the engines of an aircraft. Emissions from fuel production/refining or transport of fuels were not considered. Another issue compared was Local Area Pollution (LAP), which is a measure of the severity of emissions effect on the environment. This was examined because all emissions from HSR occur close to the surface of the earth, and hence effect the local environment, while only a portion of aircraft emissions do. This study was carried out using internationally recognized emission inventory methodologies. For the air travel emission estimate methodologies and data published by the Intergovernmental Panel on Climate Change (IPCC) and the International Civil Aviation Organization (ICAO) were used. The HSR energy use was estimated from energy use data from currently running HSR

A novel implementation of TCP Vegas for optical burst switched networks

KAUST Repository

Shihada, Basem

2010-07-01

TCP performance over bufferless Optical Burst Switched (OBS) networks could be significantly degraded due to the misinterpretation of network congestion status (referred to as false congestion detection). It has been reported that burst retransmission in the OBS domain can improve the TCP throughput by hiding burst loss events from the upper TCP layer, which can effectively reduce the congestion window fluctuation at the expense of introducing additional delay. However, the additional delay may cause performance degradation for delay-based TCP implementations that are sensitive to packet round trip time in estimating the network congestion status. In this paper, a novel implementation of TCP Vegas that adopts a threshold-based mechanism is proposed for identifying the network congestion status in OBS networks. Analytical models are developed to evaluate the throughput of conventional TCP Vegas and threshold-based Vegas over OBS networks with burst retransmission. Simulation is conducted to validate the analytical model and to compare threshold-based Vegas with a number of legacy TCP implementations, such as TCP Sack and TCP Reno. The analytical model can be used to obtain a proper threshold value that results in an optimal steady state TCP throughput.

Geohydrologic reconnaissance of Lake Mead National Recreation Area; Las Vegas Wash to Opal Mountain, Nevada

Laney, R.L.

1981-01-01

The study is a geohydrologic reconnaissance of about 170 square miles in the Lake Mead National Recreation Area from Las Vegas Wash to Opal Mountain, Nevada. The study is one of a series that describes the geohydrology of the recreation area and that indentifies areas where water supplies can be developed. Precipitation in this arid area is about 5 inches per year. Streamflow is seasonal and extremely variable except for that in the Colorado River, which adjoins the area. Pan evaporation is more than 20 times greater than precipitation; therefore, regional ground-water supplies are meager except near the Colorado River, Lake Mead, and Lake Mohave. Large ground-water supplies can be developed near the river and lakes, and much smaller supplies may be obtained in a few favorable locations farther from the river and lakes. Ground water in most of the areas probably contains more than 1,000 milligrams per liter of dissolved solids, but water that contains less than 1,000 milligrams per liter of dissolved solids can be obtained within about 1 mile of the lakes. Crystalline rocks of metamorphic, intrusive and volcanic origin crop out in the area. These rocks are overlain by conglomerate and mudstone of the Muddy Creek Formation, gravel and conglomerate of the older alluvium, and sand and gravel of the Chemehuevi Formation and younger alluvium. The crystalline rocks, where sufficiently fractured, yield water to springs and would yield small amounts of water to favorably located wells. The poorly cemented and more permeable beds of the older alluvium, Chemehuevi Formation, and younger alluvium are the better potential aquifers, particularly along the Colorado River and Lakes Mead and Mohave. Thermal springs in the gorge of the Colorado River south of Hoover Dam discharge at least 2,580 acre-feet per year of water from the volcanic rocks and metamorphic and plutonic rocks. The discharge is much greater than could be infiltrated in the drainage basin above the springs

An elemental abundance analysis of Vega has been performed using high-signal-to-noise 2.4 A/mm Reticon observations of the region 4313-4809 A. Vega is found to be a metal-poor star with a mean underabundance of 0.60 dex. The He/H ratio of 0.03 as derived from He I 4472 A suggests that the superficial helium convection zone has disappeared and that radiative diffusion is producing the photospheric abundance anomalies. 45 refs

Las Vegas' built environment facilitates the examination of these variables and active transport to school (ATS rates. The purpose of this study was to examine the influence of SECs and cul-de-sacs on ATS rates in Las Vegas, NV elementary children. Parental-reported data was collected from 11 elementary schools on ATS rates (n = 1217. SECs and cul-de-sacs were quantified for each school zone. Logistic regression models were used to predict ATS. 23.9% of students reported ATS all of the time and 31.4% some of the time. SECs per school zone ranged from 0 to 25 (mean = 11.9. Cul-de-sacs ranged from 12 to 315 (mean = 138.3. Some ATS use was predicted by distance from school (p ≤ 0.001;OR = 0.61, parental education (high school: p = 0.004;OR = 0.53, some college: p = 0.001;OR = 0.50, 4 year degree: p = 0.004;OR = 0.52 and cul-de-sacs (p ≤ 0.001;OR = 0.99.

Full Text Available La celebración del III centenario de la muerte de Lope de Vega en 1935 tuvo algunas consecuencias interesantes en el ambiente musical español. El uso de músicas de varias épocas y estilos se limitó en muchas ocasiones a la ambientación sonora en actos de homenaje o ilustraciones musicales de la época de Lope en conferencias y representaciones teatrales, en especial las obras contenidas en el trabajo de Jesús Bal y Gay publicado ese mismo año. Pero fue la convocatoria del Concurso Nacional de Bellas Artes y el homenaje que el Conservatorio de Madrid tributó al Fénix de los Ingenios lo que alentó a algunos compositores del momento a escribir música sobre las letras de Lope.

2015-01-01

Full Text Available En el presente trabajo se describen y analizan las principales obras hidráulicas del sistema de riego tradicional de la comarca de la Vega Baja del Segura, concretamente, los azudes y los acueductos. Los azudes de toma, construidos en el cauce del río Segura, representan el inicio del sistema, desde donde parte una extensa y compleja red de acueductos constituida por acequias y azarbes, como elementos fundamentales, que distribuyen el agua para el regadío. En este estudio se ha llevado a cabo una amplia y profunda investigación documental, tomado datos de campo y captado imágenes in situ que, junto con los diagramas aportados, resultan imprescindibles para comprender la magnitud del sistema. Los resultados obtenidos han servido no sólo para catalogar y caracterizar los elementos que integran el sistema hidráulico del regadío tradicional de la Vega Baja del Segura, sino también para poner de manifiesto un ejemplo real de optimización de recursos hídricos en una zona del sureste peninsular español de escasa e irregular pluviometría. Asimismo, el estudio efectuado revela un sistema de riego sumamente eficiente desde un punto de vista cuantitativo y no tanto desde el cualitativo, debido a la presencia, entre otros contaminantes, de altas concentraciones de sales.

Full Text Available Lope de Vega’s corpus of plays is one of the most studied of Spanish Baroque theater, although it still presents numerous problems that need to be solved. In this article I study the extant manuscript of a play entitled Mujeres y criados in relation to a play by Lope of the same title, which several catalogues consider lost. In the first part of my paper I prove Lope’s authorship of the play based on internal elements of the text and the manuscript’s relation to several seventeenth-century documents. In the second part of this article I study the most relevant characteristics of this play. I focus my attention on the traits of the urban comedy it presents, the subversion of certain themes —such as social hierarchies or honor— that takes place and the predominant role Lope gave women in the play’s plot.El corpus dramático de Lope de Vega es uno de los más estudiados en el teatro barroco español, pero todavía encierra numerosas lagunas que quedan por aclarar. En el presente trabajo estudio el manuscrito que se conserva de una comedia titulada Mujeres y criados en relación con una comedia homónima de Lope que varios catálogos dan por perdida. En la primera parte demuestro la autoría lopesca de la obra a partir de elementos internos del texto y de la relación que guarda el manuscrito con noticias proporcionadas por documentación de la época. En la segunda parte del artículo estudio las características más relevantes de esta comedia, destacando su inserción en el género de la comedia urbana, la subversión que se lleva a cabo de ciertos temas, como las jerarquías sociales o el honor, y el papel predominante que Lope concede a las mujeres en la trama de la obra.

Full Text Available El aprovechamiento de los posibles sistemas territoriales en los espacios desfavorecidos tiene que estar apoyado en su articulación productiva y que ésta, a su vez esté caracterizada por las iniciativas locales (micro-economía y el papel que juegan las empresas de cualquier tipo (privadas, públicas, mixtas, cooperativas, etc y los empresarios en cada una de ellas. Estos recursos económicos y productivos, unidades encargadas de organizar los factores productivos, se convierten en piezas fundamentales para lograr el crecimiento económico y la generación de empleo. El conocimiento detallado del tejido local de empresas, esto es, el conjunto de empresas y sus relaciones o los eslabonamientos productivos, resultan fundamentales para diseñar una estrategia de fomento productivo local. La falta de información sobre estos aspectos decisivos constituye una dificultad importante para el despegue de los procesos de desarrollo territorial. Aquí se ejemplariza en el caso de la Vega Media de Sevilla, resaltándose la posibilidad de establecer estrategias de sostenibilidad territorial, en una zona de contacto urbano-rural como es ésta, en función al aprovechamiento de los sistemas socio-productivos locales.

Métrica, tropos y figuras en las Anotaciones de Fernando de Herrera

Directory of Open Access Journals (Sweden)

Torre, Esteban

Full Text Available In the year 1580 in Seville, the Works of Garcilaso de la Vega with Annotations by Fernando de Herrera were first published, in which he edits and comments on thirty-five sonnets, five songs, two elegies, one letter, and three eclogues by the Toledo-born poet. With the exception of the letter, each of the other poetic formats is followed by an extensive dissertation of a largely historical and scholarly kind. Yet, what is of greatest interest are the specific comments he makes upon concrete lines of verse, comments which reveal him as possessing a thorough knowledge of the poetic theories in vogue during the second half of the sixteenth century, and also as an extraordinarily perceptive and sensitive literary critic. In this discussion his numerous references to metrical-based issues, as well as to tropological and figurative language, are mulled over, analyzed, and systematized.En el año 1580, se publicaron por primera vez en Sevilla las Obras de Garcilaso de la Vega con anotaciones de Fernando de Herrera, que edita y comenta treinta y cinco sonetos, cinco canciones, dos elegías, una epístola y tres églogas del poeta toledano. Con excepción de la epístola, cada una de las otras formas poemáticas va seguida de una extensa disertación de corte fundamentalmente histórico y erudito. Pero lo más interesante son los comentarios puntuales que hace a determinados versos, que nos revelan a un profundo conocedor de las teorías poéticas vigentes en la segunda mitad del siglo XVI y a un crítico literario extraordinariamente perspicaz y sensible. Se reúnen, analizan y sistematizan aquí sus numerosísimas referencias a las cuestiones métricas y al lenguaje tropológico y figurado.

[Plastic repair of tricuspid valve: Carpentier's ring annuloplasty versus De VEGA technique].

Tricuspid valve disease has been neglected for a long time by cardiologists and surgeons, but for some years now leakage of tricuspid valve has been demonstrated as a prognostic factor in the evolution of patients with left heart valve disease undergoing surgery. Several techniques for plastic repair of tricuspid valve have been developed and the published studies differ on the results of these techniques; we conducted this study to assess the results of plastic repair of tricuspid valve in a population of patients with a high prevalence of rheumatic disease and to compare Carpentier's ring annuloplasty techniques with DEVEGA plasty. We conducted a retrospective study of patients undergoing plastic repair of tricuspid valve in the Department of Cardiology at the Medicine University of Sfax over a period of 25 years. We compared the results from the Group 1 (Carpentier's ring annuloplasty) with Group 2 (DeVEGA plasty). 91 patients were included in our study, 45 patients in the Group 1 and 46 patients in the Group 2. Most patients had mean or severe TI (83%) before surgery, ring dilation was observed in 90% of patients with no significant difference between the two groups. Immediate results were comparable between the two techniques but during monitoring recurrent, at least mean, insufficiency was significantly more frequent in the DeVEGA plasty Group. The predictive factors for significant recurring long term TI were DeVEGA technique (OR=3.26[1.12-9.28]) in multivariate study and preoperative pulmonary artery systolic pressure (OR=1.06 (1.01-1.12)). Plastic repair of tricuspid valve using Carpentier's ring seems to guarantee better results than DeVEGA plasty. On the other hand, preoperative high PASP is predictive of recurrent leakage of tricuspid valve even after plasty; hence the importance of surgery in the treatment of patients at an early stage of the disease.

Annuloplasty is performed for significant functional tricuspid regurgitation even if it is presumed that in some cases the regurgitation will regress spontaneously after correction of the left-sided lesion. In an attempt to avoid the drawbacks of a permanent annuloplasty, we used a reabsorbable De Vega annuloplasty in a selected group of patients. Of 73 patients with functional tricuspid regurgitation operated on between May 1989 and May 1991, 25 with pulmonary arteriolar resistance below 400 dyne.sec.cm-5 underwent a De Vega annuloplasty with 2-0 polydioxanone suture. The diagnosis of significant functional tricuspid regurgitation (mean 2.74 +/- 1.05) was established by transthoracic color Doppler echocardiography in all patients. The degree of functional tricuspid regurgitation and pulmonary arteriolar resistance were measured with the patients anesthetized. In 16 patients the regurgitation remained severe (3+ to 4+) and in 9 it was moderate (2+). Twenty-three patients had mitral (12 repairs, 11 replacements) and 9 had aortic (4 repairs, 5 replacements) valve operations. The immediate postbypass residual functional tricuspid regurgitation was 0 to 1+ in 23 and 0 in 2. There was 1 (4%) operative death. The maximum follow-up period was 24 months (mean 13.9 months). There were 2 (8.3%) late deaths. Six patients underwent reoperation because of mitral dysfunction. Four of them who were reoperated on between 2 and 5 weeks after the initial procedure showed no recurrence of functional tricuspid regurgitation. The other 2, reoperated on at 5 and 10 months after the first operation, had recurrence of functional tricuspid regurgitation. Visual inspection of these two tricuspid valves showed a dilated anulus with otherwise normal valves. All surviving patients are in New York Heart Association functional class I or II without significant functional tricuspid regurgitation (mean 0.78 +/- 0.56). We concluded that functional tricuspid regurgitation in patients with low

Geogenic dust from arid environments is a possible inhalation hazard for humans, especially when using off-road vehicles that generate significant dust. This study focused on immunotoxicological and neurotoxicological effects following subacute exposure to geogenic dust generated from sediments in the Nellis Dunes Recreation Area near Las Vegas, Nevada that are particularly high in arsenic; the naturally-occurring arsenic concentrations in these surficial sediments ranged from 4.8 to 346 μg/g. Dust samples from sediments used in this study had a median diameter of 4.5 μm and also were a complex mixture of naturally-occurring metals, including aluminum, vanadium, chromium, manganese, iron, cobalt, copper, zinc, strontium, cesium, lead, uranium, and arsenic. Adult female B6C3F1 mice exposed via oropharyngeal aspiration to 0.01 to 100 mg dust/kg body weight, four times, a week apart, for 28 days, were evaluated 24 h after the last exposure. Peripheral eosinophils were increased at all concentrations, serum creatinine was dose responsively increased beginning at 1.0 mg/kg/day, and blood urea nitrogen was decreased at 10 and 100 mg/kg/day. Antigen-specific IgM responses and natural killer cell activity were dose-responsively suppressed at 0.1 mg/kg/day and above. Splenic CD4 + CD25 + T cells were decreased at 0.01, 0.1, 10, and 100 mg/kg/day. Antibodies against MBP, NF-68, and GFAP were selectively reduced. A no observed adverse effect level of 0.01 mg/kg/day and a lowest observed adverse effect level of 0.1 mg/kg/day were determined from IgM responses and natural killer cell activity, indicating that exposure to this dust, under conditions similar to our design, could affect these responses. - Highlights: • Toxicity of geogenic dust from arsenic-rich sediment in Nevada was characterized. • The geogenic dust is a mixture of many metals and crystalline silica. • Geogenic dust exposure decreased IgM antibodies and natural killer cell activity.

In 2009, the state of Nevada received nearly $40 million in Neighborhood Stabilization Funds from the Department of Housing and Urban Development to use to stabilize communities that have suffered from foreclosures and abandonment. In order to provide guidance to local officials and maximize how effectively this NSP funding is used in retrofitting homes, the CARB team provided design specifications, energy modeling, and technical support for the BARA team and its local partners—Better Building Performance, Nevada Energy Star Partners Green Alliance, and Home Free Nevada—for two retrofit test homes. One home demonstrated a modest retrofit and the other a deep energy retrofit. This report describes the retrofit packages, which were used as an educational experience for home performance professionals, building trades, remodelers, and the general public.

Often it is claimed that big investments are the only way to success in tourism and the experience economy. Only by building some of the world's biggest hotels - like the ones in Dubai or Las Vegas where hotels with 3-4,000 rooms are not uncommon - success can be achieved. It is understandable...... that hotels have to be big in Las Vegas in order to secure a good return on investment. It is also understandable that they build big hotels when 37 million people came to visit and 22,000 conventions were held in Las Vegas in 2004 according to the official website of Las Vegas (www.lasvegasnevada.gov/factsstatistics/funfacts.htm)....

Clumpy structure in the debris disk around Vega has been previously reported at millimeter wavelengths and attributed to concentrations of dust grains trapped in resonances with an unseen planet. However, recent imaging at similar wavelengths with higher sensitivity has disputed the observed structure. We present three new millimeter-wavelength observations that help to resolve the puzzling and contradictory observations. We have observed the Vega system with the Submillimeter Array (SMA) at a wavelength of 880 {mu}m and an angular resolution of 5''; with the Combined Array for Research in Millimeter-wave Astronomy (CARMA) at a wavelength of 1.3 mm and an angular resolution of 5''; and with the Green Bank Telescope (GBT) at a wavelength of 3.3 mm and angular resolution of 10''. Despite high sensitivity and short baselines, we do not detect the Vega debris disk in either of the interferometric data sets (SMA and CARMA), which should be sensitive at high significance to clumpy structure based on previously reported observations. We obtain a marginal (3{sigma}) detection of disk emission in the GBT data; the spatial distribution of the emission is not well constrained. We analyze the observations in the context of several different models, demonstrating that the observations are consistent with a smooth, broad, axisymmetric disk with inner radius 20-100 AU and width {approx}> 50 AU. The interferometric data require that at least half of the 860 {mu}m emission detected by previous single-dish observations with the James Clerk Maxwell Telescope be distributed axisymmetrically, ruling out strong contributions from flux concentrations on spatial scales of {approx}<100 AU. These observations support recent results from the Plateau de Bure Interferometer indicating that previous detections of clumpy structure in the Vega debris disk were spurious.

Supplemental Investigation Plan for FFACO Use Restrictions, Nevada Test Site, Nevada, Revision 0

Energy Technology Data Exchange (ETDEWEB)

Lynn Kidman

2008-02-01

This document is part of an effort to re-evaluate all FFACO URs against the current RBCA criteria (referred to in this document as the Industrial Sites [IS] RBCA process) as defined in the Industrial Sites Project Establishment of Final Action Levels (NNSA/NSO, 2006a). After reviewing all of the existing FFACO URs, the 12 URs addressed in this Supplemental Investigation Plan (SIP) could not be evaluated against the current RBCA criteria as sufficient information about the contamination at each site was not available. This document presents the plan for conducting field investigations to obtain the needed information. This SIP includes URs from Corrective Action Units (CAUs) 326, 339, 358, 452, 454, 464, and 1010, located in Areas 2, 6, 12, 19, 25, and 29 of the Nevada Test Site, which is approximately 65 miles northwest of Las Vegas, Nevada; and CAU 403, located in Area 3 of the Tonopah Test Range, which is approximately 165 miles north of Las Vegas, Nevada.

The VEGA (Verification Experiments of radionuclides Gas/Aerosol release) program is being performed at JAERI to clarify mechanisms of radionuclides release from irradiated fuel during severe accidents and to improve source term predictability. The fifth VEGA-5 test was conducted in January 2002 to confirm the reproducibility of decrease in cesium release under elevated pressure that was observed in the VEGA-2 test and to investigate the release behavior of short-life radionuclides. The PWR fuel of 47 GWd/tU after about 8.2 years of cooling was re-irradiated at Nuclear Safety Research Reactor (NSRR) for 8 hours before the heat-up test. After that, the two pellets of 10.9 g without cladding were heated up to about 2,900 K at 1.0 MPa under the inert He condition. The experiment reconfirmed the decrease in cesium release rate under the elevated pressure. The release data on short-life radionuclides such as Ru-103, Ba-140 and Xe-133 that have never been observed in the previous VEGA tests without re-irradiation was obtained using the {gamma} ray measurement.

Particle count and black carbon measurements at schools in Las Vegas, NV and in the greater Salt Lake City, UT area.

Science.gov (United States)

Brown, Steven G; Vaughn, David L; Roberts, Paul T

2017-11-01

As part of two separate studies aimed to characterize ambient pollutant concentrations at schools in urban areas, we compare black carbon and particle count measurements at Adcock Elementary in Las Vegas, NV (April-June 2013), and Hunter High School in the West Valley City area of greater Salt Lake City, UT (February 2012). Both schools are in urban environments, but Adcock Elementary is next to the U.S. 95 freeway. Black carbon (BC) concentrations were 13% higher at Adcock compared to Hunter, while particle count concentrations were 60% higher. When wind speeds were low-less than 2 m/sec-both BC and particle count concentrations were significantly higher at Adcock, while concentrations at Hunter did not have as strong a variation with wind speed. When wind speeds were less than 2 m/sec, emissions from the adjacent freeway greatly affected concentrations at Adcock, regardless of wind direction. At both sites, BC and particle count concentrations peaked in the morning during commute hours. At Adcock, particle count also peaked during midday or early afternoon, when BC was low and conditions were conducive to new particle formation. While this midday peak occurred at Adcock on roughly 45% of the measured days, it occurred on only about 25% of the days at Hunter, since conditions for particle formation (higher solar radiation, lower wind speeds, lower relative humidity) were more conducive at Adcock. Thus, children attending these schools are likely to be exposed to pollution peaks during school drop-off in the morning, when BC and particle count concentrations peak, and often again during lunchtime recess when particle count peaks again. Particle count concentrations at two schools were shown to typically be independent of BC or other pollutants. At a school in close proximity to a major freeway, particle count concentrations were high during the midday and when wind speeds were low, regardless of wind direction, showing a large area of effect from roadway emissions

An experimental program, Verification Experiments of radionuclides Gas/Aerosol release (VEGA), was initiated at JAERI from September 1999 to improve source term predictabilities for hypothetical severe accidents. In the experiment, a short fuel segment taken from LWR fuels irradiated in Japanese power reactors is inductively heated to high temperatures (∼3273K) in a hot cell under high pressure conditions up to 1.0MPa. Particularly, a focus will be placed on the release and transport behaviors of low-volatile fission products (FP), actinides and short-life FP which have not been well investigated in previous studies. This experimental apparatus was completed in February 1999 and three experiments were performed by the end of 2000. Most of these experiments were successfully conducted, but some problems were also found. Especially, in the first VEGA-1 test with the purpose of shakedown and reference data acquisition, there were problems such as flow blockage at the outlet of furnace due to structure melting, malfunction of heaters and so on. Therefore, the design for these defective parts was changed for future experiments. Moreover, the apparatus is not so big but the entire processes are very complicated. Accordingly, the operators should well understand the details of the apparatus including the recent change of design. This report describes outlines of the VEGA apparatus and the procedures for operation and maintenance. (author)

A rediscussion of the atmospheric extinction and the absolute spectral-energy distribution of Vega

International Nuclear Information System (INIS)

Hayes, D.S.; Latham, D.W.

1975-01-01

For both the Lick and the Palomar calibrations of the spectral-energy distribution of Vega, the atmospheric extinction was treated incorrectly. We present a model for extinction in the Earth's atmosphere and use this model to calculate corrections to the Lick and Palomar calibrations. We also describe a method that can be used to fabricate mean extinction coefficients for any mountain observatory. We combine selected portions of the corrected Lick and corrected Palomar calibrations with the new Mount Hopkins calibration to generate an absolute spectral-energy distibution of Vega over the wavelength range 3300--10,800 A. Until better measurements become available, we recommend the use of this calibration for all practical applications

NEW CONSTRAINTS ON COMPANIONS AND DUST WITHIN A FEW AU OF VEGA

International Nuclear Information System (INIS)

Mennesson, B.; Serabyn, E.; Martin, S. R.; Liewer, K.; Mawet, D.; Hanot, C.

2011-01-01

We report on high contrast near-infrared (∼2.2 μm) observations of Vega obtained with the Palomar Fiber Nuller, a dual sub-aperture rotating coronagraph installed at the Palomar Hale telescope. The data show consistent astrophysical null depth measurements at the ≅ 10 -3 level or below for three different baseline orientations spanning 60 deg in azimuth, with individual 1σ uncertainties ≤7 x 10 -4 . These high cancellation and accuracy levels translate into a dynamic range greater than 1000:1 inside the diffraction limit of the 5 m telescope beam. Such high contrast performance is unprecedented in the near-infrared and provides improved constraints on Vega's immediate (≅20 to 250 mas, or ≅0.15 to 2 AU) environment. In particular, our measurements rule out any potential companion in the [0.25-1 AU] region contributing more than 1% of the overall near-infrared stellar flux, with limits as low as 0.2% near 0.6 AU. These are the best upper limits established so far by direct detection for a companion to Vega in this inner region. We also conclude that any dust population contributing a significant (≥1%) near-infrared thermal excess can arise only within 0.2 AU of the star, and that it must consist of much smaller grains than in the solar zodiacal cloud. Dust emission from farther than ≅2 AU is also not ruled out by our observations, but would have to originate in strong scattering, pointing again to very small grains.

Ultra-high signal-to-noise, high dispersion spectroscopy over the wavelength range λλ4519-4535 shows Vega to be a rapidly rotating star with V eq of 211 km s -1 seen almost pole-on. The analysis of five independent series of spectroscopic data is combined with analyses of the hydrogen lines, Hγ, Hβ, and Hα, and the latest absolute continuum flux for Vega to yield the following results: Vsin i = 20.8 ± 0.2 km s -1 , polar T eff = 10, 000 ± 30 K, polar log g = 4.04 ± 0.01 dex, V eq = 211 ± 4 km s -1 , breakup fraction = 0.81 ± 0.02, microturbulence (ξ T ) = 1.0 ± 0.1 km s -1 , macroturbulence (ζ) = 7.4 ± 0.5 km s -1 , and an inclination i = 5. 0 7 ± 0. 0 1. The variations in T eff and log g over the photosphere total 1410 K and 0.26 dex, respectively, while the mean temperature is 9560 ± 30 K and log g is 3.95 ± 0.01 dex. Low level variations in the Ti II 4529 A profile are also illustrated.

We present the design and the first experimental characterization of VEGA, an Application Specific Integrated Circuit (ASIC) designed to read out large area monolithic linear Silicon Drift Detectors (SDD’s). VEGA consists of an analog and a digital/mixed-signal section to accomplish all the functionalities and specifications required for high resolution X-ray spectroscopy in the energy range between 500 eV and 50 keV. The analog section includes a charge sensitive preamplifier, a shaper with 3-bit digitally selectable shaping times from 1.6 µs to 6.6 µs and a peak stretcher/sample-and-hold stage. The digital/mixed-signal section includes an amplitude discriminator with coarse and fine threshold level setting, a peak discriminator and a logic circuit to fulfill pile-up rejection, signal sampling, trigger generation, channel reset and the preamplifier and discriminators disabling functionalities. A Serial Peripherical Interface (SPI) is integrated in VEGA for loading and storing all configuration parameters in an internal register within few microseconds. The VEGA ASIC has been designed and manufactured in 0.35 µm CMOS mixed-signal technology in single and 32 channel versions with dimensions of 200 µm×500 µm per channel. A minimum intrinsic Equivalent Noise Charge (ENC) of 12 electrons r.m.s. at 3.6 µs peaking time and room temperature is measured and the linearity error is between −0.9% and +0.6% in the whole input energy range. The total power consumption is 481 µW and 420 µW per channel for the single and 32 channels version, respectively. A comparison with other ASICs for X-ray SDD’s shows that VEGA has a suitable low noise and offers high functionality as ADC-ready signal processing but at a power consumption that is a factor of four lower than other similar existing ASICs.

The paper is concerned with systematic description of experimental data from the impact plasma detector SP-1 on the Vega-1 and Vega-2 space probes. The SP-1 device works on the principle of measuring plasma cloud charge resulting from the dust-thick target impact. Analysis of measurement results showed that dust particle mass spectrum grows with mass decrease in the 10 -4 -10 -16 g mass range. The dust coma consists of several envelopes or paraboloids with different characteristics, that supposes existence of different particles; small mass particles are observed beyond main paraboloids with apexes of 26.5 or 45 thous. km. Examples of particle evolution (including their decay) during their scattering in coma are presented. The cometary dust particles in the mass range below 10 -14 g have the density of approximately 0.1-0.3 g/cm 3 in external coma close to 1 g/cm 3 in internal coma. Particles in ≥10 -12 mass range have primarily low density or complex structure

Investigations of the Effects of Synthetic Chemicals on the Endocrine System of Common Carp in Lake Mead, Nevada and Arizona

Introduction: Lake Mead is the largest reservoir by volume in the United States and was created by the construction of the 221-meter high Hoover Dam in 1935 at Black Canyon on the lower Colorado River between Nevada and Arizona (fig. 1). Inflows of water into the lake include three rivers, Colorado, Virgin, and Muddy; as well as Las Vegas Wash, which is now perennial because of discharges from municipal wastewater treatment plants (Covay and Leiker, 1998) and urban stormwater runoff. As the population within the Las Vegas Valley began to increase in the 1940s, the treated effluent volume also has increased and in 1993 it constituted about 96 percent of the annual discharge of Las Vegas Wash (Bevans and others, 1996). The mean flow of Las Vegas Wash into Las Vegas Bay from 1992 to 1998 was about 490,000 m3/d (Preissler and others, 1999) and in 2001 increased to 606,000 m3/d (U.S. Bureau of Reclamation, 2001). The nutrient concentration in most areas of the lake is low, but wastewater discharged into Las Vegas Bay has caused an increased level of nutrients and primary productivity (aquatic plant and algal production) in this area of the lake (LaBounty and Horn, 1997). A byproduct of this increase in productivity has been the establishment of an important recreational fishery in Las Vegas Bay. However, concentrations of chlorophyll a (a measure of algal biomass) have also increased (LaBounty and Horn, 1997). In the spring of 2001, parts of Lake Mead experienced massive algal blooms. In addition to nutrient loading by wastewater, the presence of numerous synthetic chemicals in water, bottom sediments, and in fish tissue also has been reported (Bevans and others, 1996). Synthetic chemicals discharging into Las Vegas Bay and Lake Mead (fig. 1) originate from several sources that include surplus residential-irrigation water runoff, stormwater runoff, subsurface inflow, and tertiary treated sewage effluent discharging from three sewage-treatment plants. Chemicals detected

The VEGA program has been performed at JAERI to investigate the release of transuranium and FP including non-volatile and short-life radionuclides from Japanese PWR/BWR irradiated fuel at ∼3000degC under high pressure condition up to 1.0 MPa.

The VEGA program has been performed at JAERI to clarify the mechanism of FP release from irradiated PWR/BWR fuels including MOX fuel and to improve predictability of the source term. The principal purposes are to investigate the release of actinides and FPs including non-volatile radionuclides from irradiated fuel at 3000degC under high pressure condition up to 1.0 MPa. The short-life radionuclides will be accumulated by re-irradiation of test fuel just before the experiment using the JAERI's research reactor such as JRR-3 or NSRR. The test facility was installed into the beta/gamma concrete No.5 cell at RFEF and completed in February, 1999. Before the first VEGA-1 test in September, 1999, a preliminary test using a cold simulant, cesium iodide (CsI) was performed to confirm the fundamental capabilities of the test facility. The test results showed that the trapping efficiency of the aerosol filters is about 98%. The amount of CsI which arrived at the downstream pipe of the filters was quite small while a small amount of I 2 gas which can pass through the filters was condensed just before the cold condenser as expected in the design.

Exposure to geogenic particulate matter (PM) comprised of mineral particles has been linked to human health effects. However, very little data exist on health effects associated with geogenic dust exposure in natural settings. Therefore, we characterized particulate matter size, metal chemistry, and health effects of dust collected from the Nellis Dunes Recreation Area (NDRA), a popular off-road vehicle area located near Las Vegas, NV. Adult female B6C3F1 mice were exposed to several concentrations of mineral dust collected from active and vegetated sand dunes in NDRA. Dust samples (median diameter: 4.4 μm) were suspended in phosphate-buffered saline and delivered at concentrations ranging from 0.01 to 100 mg dust/kg body weight by oropharyngeal aspiration. ICP-MS analyses of total dissolution of the dust resulted in aluminum (55,090 μg/g), vanadium (70 μg/g), chromium (33 μg/g), manganese (511 μg/g), iron (21,600 μg/g), cobalt (9.4 μg/g), copper (69 μg/g), zinc (79 μg/g), arsenic (62 μg/g), strontium (620 μg/g), cesium (13 μg/g), lead 25 μg/g) and uranium (4.7 μg/g). Arsenic was present only as As(V). Mice received four exposures, once/week over 28-days to mimic a month of weekend exposures. Descriptive and functional assays to assess immunotoxicity and neurotoxicity were performed 24 h after the final exposure. The primary observation was that 0.1 to 100 mg/kg of this sand dune derived dust dose-responsively reduced antigen-specific IgM antibody responses, suggesting that dust from this area of NDRA may present a potential health risk. - Graphical abstract: During periods of heavy wind erosion, dense dust clouds of locally emitted geogenic dust enrobe the central Nellis Dune Recreation Area dunes. - Highlights: • Toxicological effects were characterized specific to geogenic dust exposure from a recreational sand dune site in Nevada. • The geogenic dust is a mixture of many metals and crystalline silica. • Exposure to geogenic dust dose

Male Largemouth Bass were sampled from two locations in Lake Mead (USA), a site influenced by treated municipal wastewater effluent and urban runoff (Las Vegas Bay), and a reference site (Overton Arm). Samples were collected in summer (July '07) and spring (March '08) to assess general health, endocrine and reproductive biomarkers, and compare contaminant body burdens by analyzing 252 organic chemicals. Sperm count and motility were measured in spring. Contaminants were detected at much higher frequencies and concentrations in fish from Las Vegas Bay than Overton Arm. Those with the highest concentrations included PCBs, DDTs, PBDEs, galaxolide, and methyl triclosan. Fish from Las Vegas Bay also had higher Fulton condition factor, hepatosomatic index, and hematocrit, and lower plasma 11-ketotestosterone concentration (KT). Gonadosomatic index (GSI) and sperm motility did not differ between sites, but sperm count was lower by nearly 50% in fish from Las Vegas Bay. A positive association between KT and GSI was identified, but this association was nonlinear. On average, maximal GSI was reached at sub-maximal KT concentrations. In conclusion, the higher concentration of contaminant body burdens coupled with reduced levels of KT and sperm count in fish from Las Vegas Bay suggest that male reproductive condition was influenced by contaminant exposures. Also, the nonlinear KT-GSI association provided a framework to understand why GSI was similar between male bass from both sites despite their large difference in KT, and also suggested the existence of post-gonadal growth functions of KT at high concentrations.

Full Text Available Abstract:In this work I study the theme of fake insanity and foolishness in Spanish Baroque Drama, starting with the work of Lope de Vega. In the first place, I consider some important sources in Italian Drama, specially Grazzini’s La Spiritata and Girolamo Bargagli’s La Pellegrina. Afterwards, I analyse in chronological order some of Lope’s plays that introduce this theme in Hispanic Theater, written at the turn of the XVIIth Century, such as Los locos de Valencia and El mármol de Felisardo; until many late plays by Lope and other playwrights that kept on reproducing the literary elements of those early comedias. In this survey, I examine the metatheatrical sense of fake insanity, the dramatic subgenres where it was featured, its importance for the plots, and its relation to other forms of dramatic deception, like the woman in male disguise and the nobleman as servant; as well as some dramatic and literary devices it relied on: the different kinds of simulated madness, its discoursive features, and the motif of the fake wedding. Resumen:En este trabajo se analiza el desarrollo del tema de la locura y la simpleza fingida en el teatro barroco español, a partir de la obra de Lope de Vega. Primero, se consideran algunos importantes antecedentes italianos, especialmente las obras La Spiritata, de Grazzini, y La Pellegrina, de Girolamo Bargagli. Después, se analizan con detalle y en orden cronológico algunas comedias del Fénix escritas en la última década del siglo XVI y primera del XVII en que introduce este tema en el teatro hispánico, como Los locos de Valencia o El mármol de Felisardo, hasta mencionar varias obras tardías del propio Lope y otros autores que continuaron reproduciendo los recursos de aquellas comedias tempranas. En este recorrido, se hace énfasis en el carácter metateatral de la locura fingida, los subgéneros dramáticos en la que fue incluida, importancia argumental, formas de caracterización y relación con

Retrofitting Vegas: Implementing Energy Efficiency in Two Las Vegas Test Homes

2013-04-01

In 2009, the state of Nevada received nearly forty million dollars in Neighborhood Stabilization Funds from the Department of Housing and Urban Development. The purpose of this funding was to stabilize communities that have suffered from foreclosures and abandonment. In an effort to provide guidance to local officials and maximize how effectively this NSP funding is utilized in retrofitting homes, CARB provided design specifications, energy modeling, and technical support for the Building America Retrofit Alliance (BARA) team and its local partners - Better Building Performance, Nevada Energy Star Partners Green Alliance, and Home Free Nevada - for two retrofit test homes. One home was to demonstrate a modest retrofit and the other a deep energy retrofit. Through this project, CARB has provided two robust solution packages for retrofitting homes built in this region between the 1980s and early 1990s without substantially inconveniencing the occupants. The two test homes, the Carmen and Sierra Hills, demonstrate how cost-effectively energy efficient upgrades can be implemented in the hot, dry climate of the Southwest. In addition, the homes were used as an educational experience for home performance professionals, building trades, remodelers, and the general public. In-field trainings on air-sealing, HVAC upgrades, and insulating were provided to local contractors during the retrofit and BARA documented these retrofits through a series of video presentations, beginning with a site survey and concluding with the finished remodel and test out.

We evaluated long-term results of De Vega annuloplasty measured by cylindrical sizers for functional tricuspid regurgitation (FTR) and analyzed the impact of measured annular size on the late recurrence of tricuspid valve regurgitation. Between 2001 and 2011, 177 patients (57.9±10.5 yr) underwent De Vega annuloplasty for FTR. Three cylindrical sizers (actual diameters of 29.5, 31.5, and 33.5 mm) were used to reproducibly reduce the tricuspid annulus. Long-term outcomes were evaluated and risk factor analyses for the recurrence of FTR ≥3+ were performed. Measured annular diameter indexed by patient's body surface area was included in the analyses as a possible risk factor. Operative mortality occurred in 8 patients (4.5%). Ten-year overall and cardiac death-free survivals were 80.5% and 90.8%, respectively. Five and 10-yr freedom rates from recurrent FTR were 96.5% and 93.1%, respectively. Cox proportional hazard model revealed that higher indexed annular size was the only risk factor for the recurrence of FTR (P=0.006). A minimal P value approach demonstrated that indexed annular diameter of 22.5 mm/m2 was a cut-off value predicting the recurrence of FTR. De Vega annuloplasty for FTR results in low rates of recurrent FTR in the long-term. Tricuspid annulus should be reduced appropriately considering patients' body size to prevent recurrent FTR.

VEGA, a small launch vehicle

Duret, François; Fabrizi, Antonio

1999-09-01

Several studies have been performed in Europe aiming to promote the full development of a small launch vehicle to put into orbit one ton class spacecrafts. But during the last ten years, the european workforce was mainly oriented towards the qualification of the heavy class ARIANE 5 launch vehicle.Then, due also to lack of visibility on this reduced segment of market, when comparing with the geosatcom market, no proposal was sufficiently attractive to get from the potentially interrested authorities a clear go-ahead, i.e. a financial committment. The situation is now rapidly evolving. Several european states, among them ITALY and FRANCE, are now convinced of the necessity of the availability of such a transportation system, an important argument to promote small missions, using small satellites. Application market will be mainly scientific experiments and earth observation; some telecommunications applications may be also envisaged such as placement of little LEO constellation satellites, or replacement after failure of big LEO constellation satellites. FIAT AVIO and AEROSPATIALE have proposed to their national agencies the development of such a small launch vehicle, named VEGA. The paper presents the story of the industrial proposal, and the present status of the project: Mission spectrum, technical definition, launch service and performance, target development plan and target recurring costs, as well as the industrial organisation for development, procurement, marketing and operations.

VEGA-1 and VEGA-2 space probes launched to comet Halley are equipped with identical TUENDE-M high energy particle detectors. Each TUENDE-M instrument consists of two particle telescopes viewing in the ecliptic plane at an angle of deg 55 and deg 90, respectively, to the east of the Sun. Technical data of the detectors are tabulated. In the period Dec 1984 - Apr 1985 several cases of interplanetary acceleration of charged particles up to MeV energies and a large solar flare event (27.Jan 1985) were observed by the TUENDE-M instruments. The latter event is described in detail and observation results (intensity profiles of different channels of various energies) are presented. (D.Gy.)

Ground subsidence caused by aquifer withdrawal is a geotechnical hazard that affects wide areas, causing high economic losses. This phenomenon id due to aquifer system fine soil consolidation produced by the increase of effective stress caused by piezo metric depletion. The Vega Media of the Segura River basin (SE Spain) has suffered this type of phenomena since 90s being until the moment the first documented case at a regional scale in Spain. In this work a Differential SAR Interferometry (DInSAR) remote sensing technique called Coherent Pixel (CPT) is applied to monitoring subsidence in the Vega Media of the Segura River using 81 SAR images provided by ERS-1, ERS-2 and ENVISAT European Space Agency satellites. The processing has provided the subsidence spatial distribution and temporal evolution for the whole study area showing maximum subsidence values near 15 cm for the 1994-2007 period.

The role of microbial communities in the degradation of trace organic contaminants in the environment is little understood. In this study, the biotransformation potential of 27 pharmaceuticals and endocrine-disrupting compounds was examined in parallel with a characterization of the native microbial community in water samples from four sites variously impacted by urban run-off and wastewater discharge in Lake Mead, Nevada and Arizona, USA. Samples included relatively pristine Colorado River water at the upper end of the lake, nearly pure tertiary-treated municipal wastewater entering via the Las Vegas Wash, and waters of mixed influence (Las Vegas Bay and Boulder Basin), which represented a gradient of treated wastewater effluent impact. Microbial diversity analysis based on 16S rRNA gene censuses revealed the community at this site to be distinct from the less urban-impacted locations, although all sites were similar in overall diversity and richness. Similarly, Biolog EcoPlate assays demonstrated that the microbial community at Las Vegas Wash was the most metabolically versatile and active. Organic contaminants added as a mixture to laboratory microcosms were more rapidly and completely degraded in the most wastewater-impacted sites (Las Vegas Wash and Las Vegas Bay), with the majority exhibiting shorter half-lives than at the other sites or in a bacteriostatic control. Although the reasons for enhanced degradation capacity in the wastewater-impacted sites remain to be established, these data are consistent with the acclimatization of native microorganisms (either through changes in community structure or metabolic regulation) to effluent-derived trace contaminants. This study suggests that in urban, wastewater-impacted watersheds, prior exposure to organic contaminants fundamentally alters the structure and function of microbial communities, which in turn translates into greater potential for the natural attenuation of these compounds compared to more pristine

Palabras del Dr. Jaime Eraso López ante el féretro del Dr. Gustavo Camargo Vega en la parroquia de la Sagrada Familia de Palermo el día 30 de agosto de 2016.

Por espacio de muchos años desde su llegada a Pasto y su inmediata vinculación al Hospital San Pedro, en su calidad de especialista en Urología, formando parte de un equipo de inolvidables colegas, tuve la inmensa fortuna de ser amigo de un hombre noble, querido y admirado por todos quienes lo conocimos, Gustavo Camargo Vega. Un gran ser humano cuya grandeza en la vida estribó en lo que hizo y que al pasar a la eternidad, llamado por Dios, nos ha dejado atribulados, con ese dolor en el alma que invade a Beatriz, su esposa, y a toda su familia, a todos sus amigos, a sus numerosos pacientes y a sus compañeros académicos con los que compartió como Miembro de la Junta Directiva del Capítulo de Nariño de la Academia Nacional de Medicina de Colombia, mientras me desempeñaba como Presidente, aprovechando todo su talento para la buena marcha de la Institución.

Ante mis inquietudes intelectuales, estando enfermo él, siempre tuvo la gentileza de llamarme por teléfono para expresarme con nobleza sus generosas palabras de aliento y, a raíz de la publicación de mi último libro sobre la vida del Padre Jaime Álvarez, me expresaba su identificación con las ideas de los prologuistas de la obra, demostrando así la grandeza de su alma. Cuando lo visitamos en su lecho con el Académico Dr. Leonardo Matta hace un par de meses, con gran lucidez recordábamos esa lejana época, desgraciadamente ya desaparecida, en la que servíamos al Hospital con un sentido verdaderamente humano hacia nuestros enfermos.

The National Science Foundation Advanced Technologies and Instrumentation (NSF-ATI) program is funding a new spectrometer backend for the Green Bank Telescope (GBT). This spectrometer is being built by the CICADA collaboration - collaboration between the National Radio Astronomy Observatory (NRAO) and the Center for Astronomy Signal Processing and Electronics Research (CASPER) at the University of California Berkeley.The backend is named as VErsatile GBT Astronomical Spectrometer (VEGAS) and will replace the capabilities of the existing spectrometers. This backend supports data processing from focal plane array systems. The spectrometer will be capable of processing up to 1.25 GHz bandwidth from 8 dual polarized beams or a bandwidth up to 10 GHz from a dual polarized beam.The spectrometer will be using 8-bit analog to digital converters (ADC), which gives a better dynamic range than existing GBT spectrometers. There will be 8 tunable digital sub-bands within the 1.25 GHz bandwidth, which will enhance the capability of simultaneous observation of multiple spectral transitions. The maximum spectral dump rate to disk will be about 0.5 msec. The vastly enhanced backend capabilities will support several science projects with the GBT. The projects include mapping temperature and density structure of molecular clouds; searches for organic molecules in the interstellar medium; determination of the fundamental constants of our evolving Universe; red-shifted spectral features from galaxies across cosmic time and survey for pulsars in the extreme gravitational environment of the Galactic Center.

Performance analysis of an Integrated Solar Combined Cycle using Direct Steam Generation in parabolic trough collectors

International Nuclear Information System (INIS)

Montes, M.J.; Rovira, A.; Munoz, M.; Martinez-Val, J.M.

2011-01-01

Highlights: → Solar hybridization improves the performance of CCGT in a very hot and dry weather. → The scheme analyzed is a DSG parabolic trough field coupled to the Rankine cycle. → An annual simulation has been carried out for two locations: Almeria and Las Vegas. → Economical analysis shows that this scheme is a cheaper way to exploit solar energy. → For that, solar hybridization must be limited to a small fraction of the CCGT power. - Abstract: The contribution of solar thermal power to improve the performance of gas-fired combined cycles in very hot and dry environmental conditions is analyzed in this work, in order to assess the potential of this technique, and to feature Direct Steam Generation (DSG) as a well suited candidate for achieving very good results in this quest. The particular Integrated Solar Combined Cycle (ISCC) power plant proposed consists of a DSG parabolic trough field coupled to the bottoming steam cycle of a Combined Cycle Gas Turbine (CCGT) power plant. For this analysis, the solar thermal power plant performs in a solar dispatching mode: the gas turbine always operates at full load, only depending on ambient conditions, whereas the steam turbine is somewhat boosted to accommodate the thermal hybridization from the solar field. Although the analysis is aimed to studying such complementary effects in the widest perspective, two relevant examples are given, corresponding to two well-known sites: Almeria (Spain), with a mediterranean climate, and Las Vegas (USA), with a hot and dry climate. The annual simulations show that, although the conventional CCGT power plant works worse in Las Vegas, owing to the higher temperatures, the ISCC system operates better in Las Vegas than in Almeria, because of solar hybridization is especially well coupled to the CCGT power plant in the frequent days with great solar radiation and high temperatures in Las Vegas. The complementary effect will be clearly seen in these cases, because the thermal

Importance of benthic production to fish populations in Lake Mead prior to the establishment of quagga mussels

Limnologists recently have developed an interest in quantifying benthic resource contributions to higher-level consumers. Much of this research focuses on natural lakes with very little research in reservoirs. In this study, we provide a contemporary snapshot of the food web structure of Lake Mead to evaluate the contribution of benthic resources to fish consumers. In addition, we document the available food to fishes on soft sediments and changes to the invertebrate community over 2 time periods. Benthic invertebrate food availability for fishes is greater in Las Vegas Bay than Overton Arm. Las Vegas Bay is dominated by oligochaetes, whose biomass increased with depth, while Overton Arm is dominated by chironomids, whose biomass did not change with depth. Diet and isotopic measurements indicate the fish community largely relies on benthic resources regardless of basin (Las Vegas Bay >80%; Overton Arm >92%); however, the threadfin shad likely contribute more to largemouth and striped bass production in Overton Arm versus Las Vegas Bay. A 2-time period analysis, pre and post quagga mussel establishment and during lake level declines, suggests there is no change in the density of benthic invertebrates in Boulder Basin, but there were greater abundances of select taxa in this basin by season and depth than in other basins. Given the potential of alterations as a result of the expansion of quagga mussel and the reliance of the fishery on benthic resources, future investigation of basin specific, benthic processes is recommended.

Vertebrate paleontology, stratigraphy, and paleohydrology of Tule Springs Fossil Beds National Monument, Nevada (USA)

2017-01-01

Tule Springs Fossil Beds National Monument (TUSK) preserves 22,650 acres of the upper Las Vegas Wash in the northern Las Vegas Valley (Nevada, USA). TUSK is home to extensive and stratigraphically complex groundwater discharge (GWD) deposits, called the Las Vegas Formation, which represent springs and desert wetlands that covered much of the valley during the late Quaternary. The GWD deposits record hydrologic changes that occurred here in a dynamic and temporally congruent response to abrupt climatic oscillations over the last ~300 ka (thousands of years). The deposits also entomb the Tule Springs Local Fauna (TSLF), one of the most significant late Pleistocene (Rancholabrean) vertebrate assemblages in the American Southwest. The TSLF is both prolific and diverse, and includes a large mammal assemblage dominated by Mammuthus columbi and Camelops hesternus. Two (and possibly three) distinct species of Equus, two species of Bison, Panthera atrox, Smilodon fatalis, Canis dirus, Megalonyx jeffersonii, and Nothrotheriops shastensis are also present, and newly recognized faunal components include micromammals, amphibians, snakes, and birds. Invertebrates, plant macrofossils, and pollen also occur in the deposits and provide important and complementary paleoenvironmental information. This field compendium highlights the faunal assemblage in the classic stratigraphic sequences of the Las Vegas Formation within TUSK, emphasizes the significant hydrologic changes that occurred in the area during the recent geologic past, and examines the subsequent and repeated effect of rapid climate change on the local desert wetland ecosystem.

The Nevada Test Site (NTS) is operated by the US Department of Energy's Nevada Operations Office (DOE/NV) as the site for nuclear weapons testing, now limited to readiness activities and experiments in support of the national Stockpile Stewardship Management Program. It is located in Nye County, Nevada, with the southeast corner about 105 km (65 mi) northwest of Las Vegas, Nevada. The NTS covers about 3,561 km 2 (1,375 mi 2 ), an area larger than Rhode Island. Its size is about 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range [NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands. The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS and there is great depth to slow-moving groundwater

Environmental impact study. 'Cyclical approach case study VEGA'

1993-06-01

The aim of this study has been to identify, describe and assess the environmental factors in the fuel chain which may be of significance for the possibilities of establishing biofuel-fired plants for the production of electricity and heat. The description is based on the documentation for the planned combined heat and power plant in Eskilstuna which will utilize pressurized gasification of biofuel in a combined cycle (VEGA). The study shows that the emissions from the plant are limited and do not give rise to any identifiable environmental effects. The emissions of nitrogen oxides from transportation and from fuel production are equivalent to those from combustion. The environmental consequences of a biofuel-fired plant of this size will be primarily local. The regional effects will be limited and of little significance providing that fuel extraction is not carried out in sensitive areas, transportation by road over long distances is minimized, and the removal of important nutrients through the extraction of biofuels is compensated for, for example by returning ash to the soil. 26 refs, 29 figs, 38 tabs

Spengler, R.W.; Fox, K.F. Jr.

1988-01-01

Yucca Mountain is located within the southwestern Nevada volcanic field, ∼140 km northwest of Las Vegas, Nevada, and 50 km northeast of Death Valley, California. The mountain consist of a series of long, linear, north-trending volcanic ridges that approach an 1800-m maximum elevation near The Prow. The broad intermontane alluviated valleys of Crater Flat, the Amargosa Desert, and Jackass Flats, averaging 800 to 1100 m in elevation, form the western, southern, and eastern margins of Yucca Mountain, respectively. North of The Prow, Yucca Mountain merges with other volcanic highlands that flank the southern rim of the Timber Mountain-Oasis Valley caldera complex. The stratigraphy and structure of the area are discussed. Future geologic studies will attempt to determine if faults extend beneath Yucca Mountain, and, if present, their potential effects on the hydrologic and tectonic regimes

La ‘pija de oro’ en Las aventuras del señor Maíz de Washington Cucurto. Algunas notas

2014-02-01

Full Text Available The present article consists in notes from research in progress. They address Washington Cucurto’s writing device with respect to the “negro”’s golden dick that the narrator/character Tyson Grande/Washington Cucurto/Norberto Vega implants into himself in Las aventuras del Señor Maíz (2005. We argue that such chirurgical and body prosthesis exhibits forces (in a Deleuzian sense which govern all of Cucurto’s/Vega’s production: social, economic, sexual and Latin American cultural forces. The golden dick is, then, a poetic condensation which exhibits the writing machine as a melancholic beast in whose body forces in struggle for literature become destabilized.

Full Text Available ResumenEn el contexto de los deportes colectivos, los deportistas tienen que tener la capacidad de juego definida como un don muy complejo que consiste en saber utilizar las capacidades condicionales de coordinación, intelectuales y la habilidad técnica de manera que pueda resolver bien el objetivo de juego (Lorenzo, 2002. Este objetivo se debe plantear teniendo en cuenta el aspecto funcional bajo un enfoque constructivista. La conceptualización de una situación de juego colectivo 3x3 en baloncesto nos otorga la posibilidad de constatar con mayor claridad hasta qué punto los participantes son capaces de tomar conciencia de la acción por medio de la explicación verbal, el control necesario en la acción y la estrategia de actuación. Para ello hemos utilizado la entrevista clinica y el dibujo para describir cómo los jugadores elaboran y memorizan el conocimiento implicado en las acciones motrices (Gréhaigne y Godbout, 1995; Del Valle, 1999; Rychecki, 2001; De la Vega, 2002, ya que los jugadores en todo momento están llevando a cabo procesos cognitivos a la hora de analizar, planificar y evaluar el problema que se les plantea durante el desarrollo del partido o en el tiempo dedicado al entrenamiento. Los resultados demuestran que la toma de conciencia explícita sobre la acción está en función del nivel de práctica que poseen los participantes y por otro, que las diferencias existentes entre los grupos no experto y expertos, se han constatado por las disimilitudes halladas entre el número de relaciones que los participantes han sido capaces de establecer entre los distintos elementos que conforman la tarea.AbstractIn the context of sports, player´s competence is defined as a very complex issue.

Full Text Available Parece ser que la idea de construir un auténtico palacio en el rico cazadero de El Pardo se la debemos al rey Felipe ii, que tras su vuelta de Inglaterra, siendo aún Príncipe de Asturias, encomendó al arquitecto Luis de Vega la realización de las trazas del nuevo edificio que debía emular a los vistos en el país vecino. Las obras se iniciaron en 1544 y se prolongaron hasta 1557 en que se empezó a retejar el edificio a la manera flamenca —es decir, utilizando pizarra— constituyendo esta nueva técnica una de las características más típicas de la arquitectura madrileña del periodo barroco. Al tiempo que marchaban las obras se iba confeccionando un rico programa decorativo plasmado en importantes programas iconográficos para sus techos, y adquisición de pinturas de caballete para las paredes. Pero un trágico incendio ocurrido el 13 de marzo de 1604 dio al traste con este ambicioso proyecto. El 10 de agosto de 1605, el arquitecto Francisco de Mora elevó un memorial rey Felipe III manifestando que «no quedó en toda la casa suelo que pudiese servir ni pared que no haya menester descostrarse y blanquearse si no son las de las torres».

Gaming industry employees are at higher risk than the general population for health conditions including gambling disorder. Responsible gambling training programs, which train employees about gambling and gambling-related problems, might be a point of intervention. However, such programs tend to use a "one-size-fits-all" approach rather than multiple tiers of instruction. We surveyed employees of one Las Vegas casino (n = 217) and one online gambling operator (n = 178) regarding their gambling-related knowledge and opinions prior to responsible gambling training, to examine the presence of natural knowledge groups among recently hired employees. Using k-means cluster analysis, we observed four natural groups within the Las Vegas casino sample and two natural groups within the online operator sample. We describe these natural groups in terms of opinion/knowledge differences as well as distributions of demographic/occupational characteristics. Gender and language spoken at home were correlates of cluster group membership among the sample of Las Vegas casino employees, but we did not identify demographic or occupational correlates of cluster group membership among the online gambling operator employees. Gambling operators should develop more sophisticated training programs that include instruction that targets different natural knowledge groups.

Shellnutt, J Gregory

2018-01-01

Geochemical modeling using the basalt composition analyzed at the Vega 2 landing site indicates that intermediate to silicic liquids can be generated by fractional crystallization and equilibrium partial melting. Fractional crystallization modeling using variable pressures (0.01 GPa to 0.5 GPa) and relative oxidation states (FMQ 0 and FMQ -1) of either a wet (H2O = 0.5 wt%) or dry (H2O = 0 wt%) parental magma can yield silicic (SiO2 > 60 wt%) compositions that are similar to terrestrial ferroan rhyolite. Hydrous (H2O = 0.5 wt%) partial melting can yield intermediate (trachyandesite to andesite) to silicic (trachydacite) compositions at all pressures but requires relatively high temperatures (≥ 950°C) to generate the initial melt at intermediate to low pressure whereas at high pressure (0.5 GPa) the first melts will be generated at much lower temperatures (< 800°C). Anhydrous partial melt modeling yielded mafic (basaltic andesite) and alkaline compositions (trachybasalt) but the temperature required to produce the first liquid is very high (≥ 1130°C). Consequently, anhydrous partial melting is an unlikely process to generate derivative liquids. The modeling results indicate that, under certain conditions, the Vega 2 composition can generate silicic liquids that produce granitic and rhyolitic rocks. The implication is that silicic igneous rocks may form a small but important component of the northeast Aphrodite Terra.

Integrated Aero–Vibroacoustics: The Design Verification Process of Vega-C Launcher

Davide Bianco

2018-01-01

Full Text Available The verification of a space launcher at the design level is a complex issue because of (i the lack of a detailed modeling capability of the acoustic pressure produced by the rocket; and (ii the difficulties in applying deterministic methods to the large-scale metallic structures. In this paper, an innovative integrated design verification process is described, based on the bridging between a new semiempirical jet noise model and a hybrid finite-element method/statistical energy analysis (FEM/SEA approach for calculating the acceleration produced at the payload and equipment level within the structure, vibrating under the external acoustic forcing field. The result is a verification method allowing for accurate prediction of the vibroacoustics in the launcher interior, using limited computational resources and without resorting to computational fluid dynamics (CFD data. Some examples concerning the Vega-C launcher design are shown.

The first fission product release test VEGA-1 was conducted on September 9, 1999 in the Reactor Fuel Examination Facility (RFEF) of JAERI Tokai using two PWR pellets at burnup of 47 GWd/tU. The fuel pellet of about 10g without cladding tube was heated up to 2500degC for 10min in an inert helium atmosphere at 0.1 MPa, following two other plateaus at 1727degC (20min) and 2027degC (20min). The release of radioactive fission products was on-line measured by 4 gamma sensors watching at the fuel in a furnace, at trapped aerosols in filters, at a condenser, and at noble gases in a charcoal trap. Gamma intensity of the fuel, which was dominated by Cs-134 and Cs-137, started to decrease, when the furnace temperature started to rise to the first plateau of 1727degC from a conditioning stage at 1350degC. Following the decease, the intensity at the filters, which was located about 2.5 m downstream of the furnace following thermal gradient tubes (TGTs) to collect the aerosols, started to increase. At about the same time, the counting rate on Kr-85 at the charcoal trap at -60degC started to rise. Preliminary releases of Cs-134, Cs-137, and Ru-106, etc. were estimated from changes of gamma-ray spectrum before/after the heating test. Total releases of the nuclides, however, will be evaluated later, by comprehensive off-line measurement of the apparatus, e.g. gamma scanning, leaching and gamma spectroscopy of pipes, the TGTs, and the filters. Development of thoria components in the VEGA furnace has been progressing for the use in high temperature tests under oxidizing atmosphere. Three kinds of slip casting techniques, i.e. centrifugal casting, drain casting and solid casting, were successfully applied to fabricate inner tubes, crucibles and caps, respectively. Calcination of the thoria powder was conducted to optimize slip characteristics for casting and sintering. Fabrication of test pieces has finished, expecting for two to four sets of the components being ready for heating

The differences that the processes show respect old traditional techniques are limited to the combustibles utilized in the firing kilns. Samples characterization were done by the study of physical properties according to quality standards tries, chemical analysis of main components and stadistic study of the results, mineralogical qualitative and semicuantitative analysis by X ray diffraction and thermal analysis by DTA and thermogravimetry. The pieces of this study were initially classified in two groups according to the paste colour (red or yellow. The yellow one present a fine grain texture related with the raw materials; differential characteristics observed were partially confirmed by the results obtained. Chemical compositions are different, red pieces show a higher mechanical compression resistance, while suction and absortion values are similar. Mineralogycal composition does not show important differences between groups (1. It have been confirmed the homogenity in the parameters analyzed and the relationships between them, from the statistical factorial analysis. Temperatures reached in the firing process have beeen established according to the syntetic minerals detected in the mineralogical analysis. Physical tries results and morfological differences are due to the manual moulding process and irregular manufacturing system.

The Nevada Nuclear Waste Storage Investigations Project is preparing socioeconomic profiles of Clark County, Nevada, and communities in Clark County that could be affected by siting, construction, operation, and decommissioning of a high-level nuclear waste repository at Yucca Mountain, located in Nye County. These profiles serve as a data base for evaluating local community service impacts; store existing socioeconomic data in a uniform, readily accessible format; identify the need for additional data; and assist in developing a plan for monitoring and mitigating any significant adverse impacts that may be associated with site characterization and potential repository development. This element of the socioeconomic profiles contains an inventory of community services provided by local, county, and state agencies and volunteer organizations to residents of Las Vegas, North Las Vegas, Henderson, Boulder City, Indian Springs, and unincorporated areas of the county. Services inventoried include housing, growth management, general government, education, police protection, transportation networks, public clinics, private health personnel, parks and recreation, social services, libraries, ambulances, electric power, natural gas, water, sewers and wastewater treatment, solid waste, and fire protection. The report includes a summary overview of service providers in Clark County, discussions of the services provided to residents of communities in Clark County that may be affected by Project activities, and a description of service providers whose service areas are not limited to the incorporated areas of Clark County. Data presented in this profile were collected through March of 1985. Data collection efforts are ongoing and this profile will be updated periodically

Context. A crucial issue in star formation is to understand the physical mechanism by which mass is accreted onto and ejected by a young star. To derive key constraints on the launching point of the jets and on the geometry of the winds, the visible spectro-polarimeter VEGA installed on the CHARA optical array can be an efficient means of probing the structure and the kinematics of the hot circumstellar gas at sub-AU. Aims: For the first time, we observed the Herbig Ae star AB Aur in the Hα emission line, using the VEGA low spectral resolution (R = 1700) on two baselines of the array. Methods: We computed and calibrated the spectral visibilities of AB Aur between 610 nm and 700 nm in spectral bands of 20.4 nm. To simultaneously reproduce the line profile and the inferred visibility around Hα, we used a 1D radiative transfer code (RAMIDUS/PROFILER) that calculates level populations for hydrogen atoms in a spherical geometry and that produces synthetic spectro-interferometric observables. Results: We clearly resolved AB Aur in the Hα line and in a part of the continuum, even at the smallest baseline of 34 m. The small P-Cygni absorption feature is indicative of an outflow but could not be explained by a spherical stellar wind model. Instead, it favors a magneto-centrifugal X-disk or disk-wind geometry. The fit of the spectral visibilities from 610 to 700 nm could not be accounted for by a wind alone, so another component inducing a visibility modulation around Hα needed to be considered. We thus considered a brightness asymmetry possibly caused by large-scale nebulosity or by the known spiral structures. Conclusions: Thanks to the unique capabilities of VEGA, we managed to simultaneously record for the first time a spectrum at a resolution of 1700 and spectral visibilities in the visible range on a target as faint as mV = 7.1. It was possible to rule out a spherical geometry for the wind of AB Aur and provide realistic solutions to account for the Hα emission

Differences in methylphenidate abuse rates among methadone maintenance treatment patients in two clinics.

Methylphenidate, an amphetamine-like prescription medication for attention deficit hyperactivity disorder (ADHD) was suspected as being abused among methadone maintenance treatment (MMT) patients. We tested its presence in the routine urine monitoring of all patients in both Tel Aviv and Las Vegas MMT clinics. Data on demographic and addiction history, ADHD (Wender Utah Rating Scale), cognitive impairment (Mini Mental State Exam), and lifetime DSM-IV-TR psychiatric diagnosis from admission were retrieved, and retention following 6 months. None of the 190 patients in Las Vegas tested positive for methylphenidate, while 14.7% (45/306) did in Tel Aviv. Abusers were less educated (p = 0.01), had higher ADHD scores (p = 0.02), lower cognitive scores (p = 0.05), and a higher benzodiazepine (BDZ) abuse rate (p cannabis, opiates, and cocaine abuse and infectious disease. Of the methylphenidate abuse 42.2% have take-home methadone dose privileges. Not like opiate use, being methylphenidate positive did not relate to 6-months retention. Compared to Tel Aviv, Las Vegas patients were more educated, with lower BDZ, and cocaine abuse.

The convention planning process: Potential impact of a high-level Nuclear Waste Repository in Nevada

International Nuclear Information System (INIS)

Kunreuther, H.; Easterling, D.; Kleindorfer, P.

1988-09-01

This report presents results from two studies that test whether a high level nuclear waste repository sites at Yucca Mountain, Nevada will diminish the willingness of meeting planners to schedule conventions, trade shows, and other meetings in Las Vegas. The first study, a focus group interview with nine meeting planners from the Philadelphia area, found little evidence that planners' selection decisions would be influenced by environmental hazards (e.g., earthquakes, pollution), unless planners were led to believe that these hazards would have a direct impact on convention delegates and the planner could conceivably be held personally responsible for any such impacts. Participants did point out that they would be sensitive to continued media coverage of a negative event, as this might stigmatize the city in the eyes of delegates. The results from the focus group guided the development of a larger and more formal questionnaire survey of meeting planners who were known to have selected Las Vegas for a meeting. Of the 153 planners recruited, 114 had a future meeting scheduled and 39 had arranged a meeting that was recently held in the city. Subjects first answered a number of questions that described the process by which they chose Las Vegas among the possible convention cities. They were then instructed to reconsider their decision in light of seven different scenarios pertaining to the repository at Yucca Mountain

Seventy-eight patients undergoing mitral valve surgery with or without replacement of the aortic valve also underwent procedures on the tricuspid valve over a period of 10 years. All patients were in functional class III or IV preoperatively. The procedures were performed in all patients with organic disease of the tricuspid valve (N = 44) and in those with moderate or severe functional tricuspid valvar regurgitation (N = 34). Seventy-one patients underwent DeVega's annuloplasty with or without commissurotomy. The overall mortality was 11.5%. 65 long-term survivors were followed up for a period of 6 months to 10 years (mean 5.3 years). Sixty-three patients were in functional class I or II at the last follow-up. Six patients had clinical evidence of mild to moderate tricuspid regurgitation. Regression of cardiomegaly (as judged by the chest radiograph and right ventricular hypertrophy seen in the electrocardiogram) was evident in most cases. Fifty-one of 54 patients evaluated by cross-sectional echocardiography were reported to have a functionally normal tricuspid valve. Doppler echocardiography in 28 patients showed no significant tricuspid regurgitation or stenosis in 26 patients. Eleven consecutive patients undergoing DeVega's annuloplasty were studied prospectively with pre- and postoperative Doppler echocardiography. Good correlation existed between right ventricular systolic pressures predicted by Doppler with those obtained preoperatively at cardiac catheterization. Postoperative Doppler echocardiography in these 11 patients showed complete restoration of competence of the tricuspid valve as well as normalisation of the right ventricular systolic pressure in 10 patients.

Water quality and benthic macroinvertebrate bioassessment of Gallinas Creek, San Miguel County, New Mexico, 1987-90

Upper Gallinas Creek in north-central New Mexico serves as the public water supply for the City of Las Vegas. The majority of this 84-square-mile watershed is within national forest lands managed by the U.S. Forest Service. In 1985, the Forest Service planned to conduct timber harvesting in the headwaters of Gallinas Creek. The City of Las Vegas was concerned about possible effects from logging on water quality and on water-supply treatment costs. The U.S. Geological Survey began a cooperative study in 1987 to (1) assess the baseline water-quality characteristics of Gallinas Creek upstream from the Las Vegas water-supply diversion, (2) relate water quality to State water- quality standards, and (3) determine possible causes for spatial differences in quality. During 1987-90, water-quality constituents and aquatic benthic macroinvertebrates were collected and analyzed at five sampling sites in the watershed. Specific conductance, pH, total hardness, total alkalinity, and calcium concentrations increased in a downstream direction, probably in response to differences in geology in the watershed. The water-quality standard for temperature was exceeded at the two most downstream sites probably due to a lack of riparian vegetation and low streamflow conditions. The standards for pH and turbidity were exceeded at all sites except the most upstream one. Concentrations of nitrogen species and phosphorus generally were small at all sites. The maximum total nitrogen concentration of 2.1 milligrams per liter was at the mouth of Porvenir Canyon; only one sample at this site exceeded the water-quality standard for total inorganic nitrogen. At each of the sites, 10 to 15 percent of the samples exceeded the total phosphorus standard of less than 0.1 milligram per liter. Except for aluminum and iron, almost all samples tested for trace elements contained concentrations less than the laboratory detection limit. No trace-element concentrations exceeded the State standard for domestic

The in-situ measurements of secondary electrons and sputtered ions caused by impacts of neutral particles on metallic surfaces of the Ram Faraday Cup and Plasma Impact Detector sensors in PLAZMAG-1 instrument aboard VEGA 1,2 spacecraft are used to estimate neutral particle density distribution (n n ) around comet P/Halley up to distances of approximately 3x10 σ km. Asymmetries in n n distributions along inbound and outbound legs of spacecraft trajectory are attributed to solar radiation pressure. A model calculation, taking into account solar radiation pressure, leads to 'tear drop' shaped distribution of neutral particles around the cometary nucleus. (author) 46 refs.; 11 figs

This study examined the hypothesis that exposure to sublethal concentrations of contaminants alters the gonadal condition of feral common carp Cyprinus carpio. Adult common carp in Lake Mead, Nevada, were collected from a contaminated site (Las Vegas Bay) that receives municipal and industrial effluent and from a reference site (Overton Arm) with a relatively low level of contamination. Fish were sampled seven times over a 1-year period extending over two separate spawning seasons. Morphometric and histopathological parameters of gonadal and germ cell development were determined. In males, the pattern of seasonal changes in the gonadosomatic index (GSI) was similar between the sites and showed no clear association with site-specific seasonal temperature profiles. However, Las Vegas Bay males had consistently lower GSI values and, on one of the sampling dates, a lower proportion of sperm relative to other germ cell stages (determined histologically). Further, Las Vegas Bay males had a higher incidence of gonadal macrophage aggregates, which are putative tissue biomarkers of contaminant exposure in fishes. In females, seasonal GSI profiles, the frequency of fish with postovulatory follicles (an index of spawning activity), and the timing of new follicle recruitment all showed differences between sites, but these differences generally matched differences in water temperature profile. Also, the peak size-frequency of full-grown follicles did not differ between sites, and estimates of fecundity for the second spawning season indicated that females from the reference site unexpectedly produced a lower number of gametes, Overall, site differences in gonadal condition were observed in carp of both sexes but they seemed to be associated with site differences in contaminant levels only in males. The apparent lack of association between contaminant level and gonadal condition in female carp from mildly mesotrophic Lake Mead may indicate a lack of contaminant effects in

The Economic Costs of a Shrinking Lake Mead: a Spatial Hedonic Analysis

Science.gov (United States)

Singh, A.; Saphores, J. D.

2017-12-01

Persistent arid conditions and population growth in the Southwest have taken a toll on the Colorado River. This has led to substantial drawdowns of many water reservoirs around the Southwest, and especially of Lake Mead, which is Las Vegas' main source of drinking water. Due to its importance, Lake Mead has received a great deal of media attention about its "bathtub ring" and the exposure of rock that used to be underwater. Drops in water levels have caused some local marinas to close, thereby affecting the aesthetic and recreational value of Lake Mead, which is located in the country's largest National Recreation Area (NRA), and surrounded by protected land. Although a rich literature analyzes how water quality impacts real estate values, relatively few studies have examined how dropping water levels are capitalized in surrounding residential properties. In this context, the goal of this study is to quantify how Lake Mead's water level changes are reflected in changes in local property values, an important source of tax income for any community. Since Lake Mead is the primary attraction within its recreation area, we are also concerned with how this recreation area, which is a few miles southeast of Las Vegas, is capitalized in real estate values of the Las Vegas metropolitan area as few valuation studies have examined how proximity to national parks influences residential property value. We estimate spatial hedonic and geographically weighted regression models of single family residences to delineate the value of proximity to the Lake Mead NRA and to understand how this value changed with Lake Mead's water levels. Our explanatory variables include common structural characteristics, fixed effects to account for unobserved locally constant characteristics, and specific variables such as distance to the Las Vegas strip and to downtown casinos. Because the sharpest declines in Lake Mead water levels happened in 2010 (NASA, 2010) and winter 2016 saw an unexpected

Full Text Available From the end of the XVI century and throughout the XVII, testimonies about the well-known «Juego del soldado» are abundant and varied in every genre, specially in dramatic one, given its inherent theatricality. Among the authors who used it, where it figures names such as Calderón, Luis Vélez or Sor Juana Inés de la Cruz, Lope de Vega stands out. Everything points that he was responsible for the beginning of this story, worthy of being studied in more detail. Moreover, he is the author with more cases registered, until five, which belong to different periods, genres (theatre, lyric and tale and treatments (profane and religious, and which point to the subsequent lines of development. In short, the use of this pastime by the Fénix reveals once more its ability to turn everything into literature, as well as its status as a pioneer and «trendsetter».

Perceived risk, stigma, and potential economic impacts of a high-level nuclear waste repository in Nevada

International Nuclear Information System (INIS)

Slovic, P.

1989-01-01

This paper addresses the potential for the proposed Yucca Mountain repository to have serious adverse economic impacts on the city of Las Vegas and the State of Nevada. Adverse economic impacts may be expected to result from two related social processes. One has to do with perceptions of risk and socially amplified reactions to unfortunate events associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The second process that may trigger significant adverse impacts is that of stigmatization. The conceptual underpinnings of risk perception, social amplification, and stigma are discussed in this paper and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse effects on tourism, migration, and business development

Evaluating lake stratification and temporal trends by using near-continuous water-quality data from automated profiling systems for water years 2005-09, Lake Mead, Arizona and Nevada

Science.gov (United States)

Veley, Ronald J.; Moran, Michael J.

2012-01-01

The U.S. Geological Survey, in cooperation with the National Park Service and Southern Nevada Water Authority, collected near-continuous depth-dependent water-quality data at Lake Mead, Arizona and Nevada, as part of a multi-agency monitoring network maintained to provide resource managers with basic data and to gain a better understanding of the hydrodynamics of the lake. Water-quality data-collection stations on Lake Mead were located in shallow water (less than 20 meters) at Las Vegas Bay (Site 3) and Overton Arm, and in deep water (greater than 20 meters) near Sentinel Island and at Virgin and Temple Basins. At each station, near-continual depth-dependent water-quality data were collected from October 2004 through September 2009. The data were collected by using automatic profiling systems equipped with multiparameter water-quality sondes. The sondes had sensors for temperature, specific conductance, dissolved oxygen, pH, turbidity, and depth. Data were collected every 6 hours at 2-meter depth intervals (for shallow-water stations) or 5-meter depth intervals (for deep-water stations) beginning at 1 meter below water surface. Data were analyzed to determine water-quality conditions related to stratification of the lake and temporal trends in water-quality parameters. Three water-quality parameters were the main focus of these analyses: temperature, specific conductance, and dissolved oxygen. Statistical temporal-trend analyses were performed for a single depth at shallow-water stations [Las Vegas Bay (Site 3) and Overton Arm] and for thermally-stratified lake layers at deep-water stations (Sentinel Island and Virgin Basin). The limited period of data collection at the Temple Basin station prevented the application of statistical trend analysis. During the summer months, thermal stratification was not observed at shallow-water stations, nor were major maxima or minima observed for specific-conductance or dissolved-oxygen profiles.

A figura do gato como capa para considerações mais profundas : Lope de Vega, E. T. A. Hoffmann, T. S. Eliot

OpenAIRE

2014-01-01

Cats have traditionally been writers' favourite pets. And writers who love cats often write about them or in their names. Among many others, Lope de Vega, E. T. A. Hoffmann and T. S. Eliot did. It is fascinating to analyse how three very different authors, living centuries apart in distinct countries, and writing different kinds of poetry or prose, found a similar way to express their opinions or secret grievances about women's inconstancy and the fallacy of love vows. The three of them lent ...

Lope de Vega y el poder monárquico: una puesta al día

Directory of Open Access Journals (Sweden)

Marcella Trambaioli

2012-04-01

Full Text Available The essay tries to outline the ‘state-of-the-art’ about the relationship between Lope deVega and the contemporary monarchic power. After some early studies merely concerning the politicaltheory present inside the texts, the scholars have started to analyze his historical theater in relation withhis construction of the Spanish Empire mythology, even if only recently some of them have realized thatthis glorification of both the Austrias and the Spanish nobles gets on with Lope’s self-promotionstrategies, in order to obtain an official post at court. On the contrary, some scholars, mainlyAnglosaxon, have tried to interpret his works in a critical and satyrical perspective, without consideringthe necessary contextualization of his theater. The reception theory may help studying this controversialmatter, only if it tries to match in the right way both the historical and cultural context of the authorand the cultural background of the contemporary audience.

Mesozoic and Cenozoic structural geology of the CP Hills, Nevada Test Site, Nye County, Nevada; and regional implications

1991-08-01

Detailed mapping and structural analysis of upper Proterozoic and Paleozoic rocks in the CP Hills of the Nevada Test Site, together with analysis of published maps and cross sections and a reconnaissance of regional structural relations indicate that the CP thrust of Barnes and Poole (1968) actually comprises two separate, oppositely verging Mesozoic thrust systems: (1) the west-vergent CP thrust which is well exposed in the CP Hills and at Mine Mountain, and (2) the east-vergent Belted Range thrust located northwest of Yucca Flat. West-vergence of the CP thrust is indicated by large scale west-vergent recumbent folds in both its hangingwall and footwall and by the fact that the CP thrust ramps up section through hangingwall strata toward the northwest. Regional structural relations indicate that the CP thrust forms part of a narrow sigmoidal belt of west-vergent folding and thrusting traceable for over 180 km along strike. The Belted Range thrust represents earlier Mesozoic deformation that was probably related to the Last Chance thrust system in southeastern California, as suggested by earlier workers. A pre-Tertiary reconstruction of the Cordilleran fold and thrust belt in the region between the NTS and the Las Vegas Range bears a close resemblance to other regions of the Cordillera and has important implications for the development of hinterland-vergent deformation as well as for the probable magnitude of Tertiary extension north of Las Vegas Valley. Subsequent to Mesozoic deformation, the CP Hills were disrupted by at least two episodes of Tertiary extensional deformation: (1) an earlier episode represented by pre-middle Miocene low-angle normal faults, and (2) a later, post-11 Ma episode of high-angle normal faulting. Both episodes of extension were related to regional deformation, the latter of which has resulted in the present basin and range topography of the NTS region.

Invasive quagga (Dreissena bugnesis) and zebra (Dreissena ploymorpha) mussels have rapidly spread throughout North America. Understanding the relationships between environmental variables and quagga mussels during the early stages of invasion will help management strategies and allow researchers to predict patterns of future invasions. Quagga mussels were detected in Lake Mead, NV/AZ in 2007, we monitored early invasion dynamics in 3 basins (Boulder Basin, Las Vegas Bay, Overton Arm) bi-annually from 2008-2011. Mean quagga density increased over time during the first year of monitoring and stabilized for the subsequent two years at the whole-lake scale (8 to 132 individuals·m-2, geometric mean), in Boulder Basin (73 to 875 individuals·m-2), and in Overton Arm(2 to 126 individuals·m-2). In Las Vegas Bay, quagga mussel density was low (9 to 44 individuals·m-2), which was correlated with high sediment metal concentrations and warmer (> 30°C) water temperatures associated with that basin. Carbon content in the sediment increased with depth in Lake Mead and during some sampling periods quagga density was also positively correlated with depth, but more research is required to determine the significance of this interaction. Laboratory growth experiments suggested that food quantity may limit quagga growth in Boulder Basin, indicating an opportunity for population expansion in this basin if primary productivity were to increase, but was not the case in Overton Arm. Overall quagga mussel density in Lake Mead is highly variable and patchy, suggesting that temperature, sediment size, and sediment metal concentrations, and sediment carbon content all contribute to mussel distribution patterns. Quagga mussel density in the soft sediment of Lake Mead expanded during initial colonization, and began to stabilize approximately 3 years after the initial invasion.

Perceived risk, stigma, and potential economic impacts of a high-level nuclear waste repository in Nevada

International Nuclear Information System (INIS)

Slovic, P.; Layman, M.; Kraus, N.N.; Chalmers, J.; Gesel, G.; Flynn, J.

1989-07-01

This paper describes a program of research designed to assess the potential impacts of a high-level nuclear waste repository at Yucca Mountain, Nevada, upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. Adverse economic impacts may be expected to result from two related social processes. One has to do with perceptions of risk and socially amplified reactions to ''unfortunate events'' associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The second process that may trigger significant adverse impacts is that of stigmatization. The conceptual underpinnings of risk perception, social amplification, and stigmatization are discussed in this paper and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse effects on tourism, migration, and business development

La identidad de los escritores del Siglo de Oro

Ricardo GARCÍA CÁRCEL

2009-12-01

Full Text Available La sociología de la producción de la cultura en la España del Siglo de Oro está en nuestro país más atrasada que la sociología del consumo. Para las famosas preguntas de J.P. Sartre Qué est-ce que la littérature: ¿Quién escribe las obras? y ¿Para quién escribe las obras?, tenemos hoy por hoy, pobres respuestas. En este trabajo intentaremos aportar algunos elementos de respuesta al primer interrogante. Noel Salomón en 1972 estableció tres tipos de escritores en la España del Siglo de Oro:1 Los escritores aristócratas, para quienes tomar la pluma es un arte noble del espíritu, un lujo en su existencia social palaciega. Tal es el caso del Marqués de Santillana o Garcilaso de la Vega.2 Los escritores artesanos, para quienes escribir es una profesión, una actividad para ganar el pan cotidiano. Entran en esta condición los juglares medievales, los poetas maestros de capilla (Juan del Encina, Lucas Fernández y los poetas secretarios «capellanes» del tipo de Lope de Vega hacia 1600. Unos y otros viven de su pluma a la sombra del mecenas.3 Escritores de mercado. El ejemplo más expresivo es Lope de Vega después de 1610. El teatro fue para él un importante medio de vida. Por una comedia cobraba poco más de 300 reales.

Dolores Prieto-Salceda

2007-08-01

Full Text Available Objetivo: Comprobar si las variables meteorológicas justifican el gradiente norte-sur en la mortalidad por esclerosis múltiple (EM en España. Métodos: La tasa de mortalidad por EM ajustada por edad en cada provincia de 1975 a 1998 se correlacionó con la media anual de diferentes variables meteorológicas. Resultados: Las temperaturas mínima, media y máxima, el número medio de horas de sol y el número de días soleados se correlacionaron negativamente con la mortalidad por EM, mientras que la cantidad de lluvia se correlacionó positivamente con la EM. La mayor parte de las correlaciones desaparecen al ajustar por latitud. En cambio, la mortalidad por EM está asociada con la latitud incluso después de ajustar por los factores meteorológicos. Conclusión: El gradiente norte-sur en la mortalidad por EM en España no puede explicarse completamente por factores meteorológicos. Son necesarias otras hipótesis para justicar esta asociación.Objectives: To determine whether weather conditions explain the North-South gradient in multiple sclerosis (MS mortality described in Spain. Methods: The age-adjusted MS mortality rate by Spanish provinces from 1975 to 1998 was correlated with several climatic variables. Results: MS mortality was negatively correlated with minimum, average and maximum temperatures, the mean number of hours of sunshine, and the mean number of sunny days. A positive correlation was found with the average amount of rain. Most correlations disappeared after adjusting by latitude. However, MS mortality was associated with latitude after adjusting by climatic factors. Conclusions: The North-South gradient in MS mortality in Spain cannot be fully explained by weather differences. Therefore, other hypotheses are required to explain this association.

How do arousal-inducing contexts, such as frightening or romantic television programs, influence the effectiveness of basic persuasion heuristics? Different predictions are made by three theoretical models: A general arousal model predicts that arousal should increase effectiveness of heuristics; an affective valence model predicts that effectiveness should depend on whether the context elicits positive or negative affect; an evolutionary model predicts that persuasiveness should depend on both the specific emotion that is elicited and the content of the particular heuristic. Three experiments examined how fear-inducing versus romantic contexts influenced the effectiveness of two widely used heuristics-social proof (e.g., "most popular") and scarcity (e.g., "limited edition"). Results supported predictions from an evolutionary model, showing that fear can lead scarcity appeals to be counter-persuasive, and that romantic desire can lead social proof appeals to be counter-persuasive. The findings highlight how an evolutionary theoretical approach can lead to novel theoretical and practical marketing insights.

Analysis Of Conservation Experience Of Heritage Objects In Lithuania (The Curonian Spit And Norway (The Vega Archipelago

2014-05-01

Full Text Available The Curonian Spit (Lithuania and Vega Archipelago (Norway are objects on the UNESCO World Heritage List because of their special kind of landscapes that have been formed not without human intervention. Landscapes created by nature itself or with human help are exceptional works which, as determined by the legal acts in regulation of these processes, have to be referred to as objects of cultural heritage. The cultural heritage must be protected, exhibited and viewed as objects of science and cognition. Lithuania and Norway have different conditions formed for identification, conservation and protection of these works, but both countries have recognized that protection of cultural heritage, passing it on for future generations is the duty of the state. Prospects of heritage management and development, and exchange of experience should be the top priorities for action in Lithuania.

The Nevada Test Site (NTS) is operated by the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Operations Office (NNSA/NV) as the site for nuclear weapons testing, now limited to readiness activities, experiments in support of the national Stockpile Stewardship Program, and the activities listed below. Located in Nye County, Nevada, the site's southeast corner is about 88 km (55 mi) northwest of the major population center, Las Vegas, Nevada. The NTS covers about 3,561 km2 (1,375 mi2), an area larger than Rhode Island. Its size is 46 to 56 km (28 to 35 mi) east to west and from 64 to 88 km (40 to 55 mi) north to south. The NTS is surrounded, except on the south side, by public exclusion areas (Nellis Air Force Range[NAFR]) that provide another 24 to 104 km (15 to 65 mi) between the NTS and public lands (Figure 1.0). The NTS is characterized by desert valley and Great Basin mountain topography, with a climate, flora, and fauna typical of the southwest deserts. Population density within 150 km (93 mi) of the NTS is only about 0.2 persons per square kilometer, excluding the Las Vegas area. Restricted access, low population density in the surrounding area, and extended wind transport times are advantageous factors for the activities conducted at the NTS. Surface waters are scarce on the NTS, and slow-moving groundwater is present hundreds to thousands of feet below the land surface. The sources of radionuclides include current and previous activities conducted on the NTS (Figure 2.0). The NTS was the primary location for testing of nuclear explosives in the Continental U.S. between 1951 and 1992. Historical testing above or at ground surface has included (1) atmospheric testing in the 1950s and early 1960s, (2) earth-cratering experiments, and (3) open-air nuclear reactor and rocket engine testing.

Those persons more greatly affected negatively by social violence have often survived circumstances which seemed insurmountable to others in society, who are better isolated economically and socially from social ills. Such is the case of the young students and their families in the West Las Vegas, Nevada community. This year`s Say YES Family Learning Center began in the midst of drive-by shootings, fear and apprehension on the part of both Say YES staff members and their clients. Meetings were held with community leaders and parents. Not much was done to resolve the core problems that caused the shootings, but just the communal gathering and sharing was enough to move on, to keep working, trying to make a difference for the younger generation. Though the NUC and Department of Energy administrators and support staff did their best at trying to reconcile the many differences and conflicts, tension continued to characterize the work at the Las Vegas Family Learning Centers. The staff appeared distrustful of any delays or inaction due to the frozen finances of the US government, and of the resulting cutbacks. Inclement weather in the nation`s capital did not help an already strained program. Still children and their parents and/or adult assistants learned Hands-On Family Math, Science, and Technology the Say YES way. The veteran Family Learning Center staff worked diligently despite human and bureaucratic shortcomings. Teachers in the Clark County School District were once again trained and made ready to share their knowledge daily in the classroom. This report describes the Say YES program and its implementation in West Las Vegas, NV.

Effects of rapid urbanization on streamflow, erosion, and sedimentation in a desert stream in the American Southwest

Science.gov (United States)

Whitney, John W.; Glancy, Patrick A.; Buckingham , Susan E.; Ehrenberg, Arthur C.

2015-01-01

Rapid urbanization has resulted in a series of sequential effects on a desert stream in the American Southwest. Lower Las Vegas Wash was a dry wash characterized by infrequent flood deposition when Las Vegas, Nevada was established in 1905. Wastewater effluent was discharged into the wash in low volumes for over 3 decades. Wastewater volumes increased commensurably with accelerated population growth during the late 20th century and created a sequence of feedback effects on the floodplain. Initially slow saturation of the valley fill created a desert oasis of dense floodplain vegetation and wetlands. Annual streamflow began in 1958 and erosion began a decade later with shallow incision in discontinuous channel segments. Increasing baseflow gradually enlarged channels; headcutting was active during the 1970s to 1984. The incised channels concentrated storm runoff, which accelerated local channel erosion, and in 1984 the headcuts were integrated during a series of monsoon floods. Wetlands were drained and most floodplain vegetation destroyed. Channel erosion continued unabated until engineering interventions began in the 21st century. No natural channel recovery occurred after initial urbanization effects because streamflow never stabilized in the late 20th century. A 6.6 M m3 sediment slug, eroded from the wash in ∼25 years, was deposited in Las Vegas Bay in Lake Mead. Falling reservoir levels during the 21st century are responsible for sediment redistribution and infilling of the bay. Close monitoring of impacts is recommended when urban wastewater and storm runoff are discharged on a desert wash. Channel interventions, when necessary, are advised in order to prevent costly engineering schemes of channel stabilization, flood control, and floodplain restoration.

Full Text Available Este artículo examina el motivo de las multitudes y las revoluciones de nuestro tiempo. Primeramente, se discuten las diferencias entre los conceptos de multitud y masa. Así, podemos considerar las revoluciones como acontecimientos de cambios sociales, económicos y políticos, provenientes de las clases baja y media de la sociedad. El meollo de este artículo refiere a la dignidad humana articulada a la contracción de los Estados de bienestar. Los ciudadanos están reflejando un desencanto hacia la clase política y una frustración con respecto al empeoramiento de las condiciones económicas y sociales. Podemos observar los casos de indignados en Grecia, España y Portugal pero también en los países árabes. De esta misma manera, las revoluciones de las multitudes siguen avanzando por medio de las demostraciones públicas y protestas sobre los espacios geográficos. Finalmente, las dinámicas de cambio a través de las revoluciones árabes son una cuestión compleja debido al círculo vicioso entre la tendencia autoritaria y la islámica. This article examines the reason of multitudes and revolutions in our time. First of all, it discusses the difference between the concept of multitude and mass. Consequently, revolutions can be considered as social, economic, and political events of changes, which come from the low and middle classes of the society. This article refers to the human dignity articulated with the contraction of Welfare states. Citizens are reflecting disenchantment towards the political class and frustration regarding the deterioration of social and economic conditions. We can observe angry people in Greece, Spain, and Portugal but also in Arabian countries. In this same way, revolutions of multitudes continue by means of public demonstrations and protests on geographical spaces. Finally, the dynamics of change through Arabian Revolutions are a complex matter due to the vicious circle between the authoritarian or Islamic

Floral ecology and insect visitation in riparian Tamarix sp. (saltcedar)

Andersen, D.C.; Nelson, S.M.

2013-01-01

Climate change projections for semiarid and arid North America include reductions in stream discharge that could adversely affect riparian plant species dependent on stream-derived ground water. In order to better understand this potential impact, we used a space-for-time substitution to test the hypotheses that increasing depth-to-groundwater (DGW) is inversely related to Tamarix sp. (saltcedar) flower abundance (F) and nectar production per flower (N). We also assessed whether DGW affected the richness or abundance of insects visiting flowers. We examined Tamarix floral attributes and insect visitation patterns during 2010 and 2011 at three locations along a deep DWG gradient (3.2–4.1 m) on a floodplain terrace adjacent to Las Vegas Wash, an effluent-dominated Mojave Desert stream. Flower abundance and insect visitation patterns differed between years, but no effect from DGW on either F or N was detected. An eruption of a novel non-native herbivore, the splendid tamarisk weevil (Coniatus splendidulus), likely reduced flower production in 2011.

Postwildfire preliminary debris flow hazard assessment for the area burned by the 2011 Las Conchas Fire in north-central New Mexico

Science.gov (United States)

Tillery, Anne C.; Darr, Michael J.; Cannon, Susan H.; Michael, John A.

2011-01-01

The Las Conchas Fire during the summer of 2011 was the largest in recorded history for the state of New Mexico, burning 634 square kilometers in the Jemez Mountains of north-central New Mexico. 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 321 basins burned by the Las Conchas Fire. A pair of empirical hazard-assessment models developed using data from recently burned basins throughout the intermountain western United States was 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 debris flows following the fire. In response to a design storm of 28.0 millimeters of rain in 30 minutes (10-year recurrence interval), the probabilities of debris flows estimated for basins burned by the Las Conchas Fire were greater than 80 percent for two-thirds (67 percent) of the modeled basins. Basins with a high (greater than 80 percent) probability of debris-flow occurrence were concentrated in tributaries to Santa Clara and Rio del Oso Canyons in the northeastern part of the burned area; some steep areas in the Valles Caldera National Preserve, Los Alamos, and Guaje Canyons in the east-central part of the burned area; tributaries to Peralta, Colle, Bland, and Cochiti canyons in the southwestern part of the burned area; and tributaries to Frijoles, Alamo, and Capulin Canyons in the southeastern part of the burned area (within Bandelier National Monument). Estimated debris-flow volumes ranged from 400 cubic meters to greater than 72,000 cubic meters. The largest volumes (greater than 40,000 cubic meters) were estimated for basins in Santa Clara, Los Alamos, and Water Canyons, and for two

Full Text Available Introducción: por lo común, la adicción a las drogas se trata con psicoterapia y farmacología que evita la unión de las sustancias psicoactivas a receptores específicos en el cerebro. El resultado de estos tratamientos no ha sido del todo satisfactorio, por lo que el desarrollo de terapias más eficaces representa un reto constante para tratar las adicciones. Una alternativa a la farmacología antiadictiva es la vacunación activa dirigida contra las sustancias de abuso. Objetivo: esta revisión reúne la información disponible sobre los fundamentos y avances científicos en la generación de una terapia inmunológica, que coadyuve al tratamiento de la adicción a sustancias como la heroína-morfina, la cocaína, la nicotina y la anfetamina. Método: se consideraron los reportes científicos disponibles en PubMed –de 2005 a abril de 2017–, sobre los fundamentos, la metodología empleada, los estudios preclínicos y clínicos, y los resultados obtenidos en dichas investigaciones para generar vacunas contra las drogas. Resultados: las vacunas lograron mitigar los efectos producidos por las sustancias en los estudios preclínicos en modelos de estudio en animales; sin embargo, con pacientes humanos los resultados no han sido del todo satisfactorios. Discusión y conclusiones: a pesar de los esfuerzos realizados por diferentes grupos de investigación y compañías farmacéuticas para generar vacunas terapéuticas contra el uso de diferentes drogas, ninguna ha alcanzado la fase III de estudios clínicos. En la actualidad, se continúa con los esfuerzos para lograr que las vacunas contra las adicciones alcancen su máxima eficiencia y eficacia, y contribuyan al tratamiento de la adicción a las drogas.

Perceived risk, stigma, and potential economic impacts of a high-level nuclear waste repository in Nevada

International Nuclear Information System (INIS)

Slovic, P.; Layman, M.; Kraus, N.; Flynn, J.; Chalmers, J.; Gesell, G.

1991-01-01

This study investigates the potential impacts of the proposed nuclear waste repository at Yucca Mountain, Nevada, upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. Adverse impacts may be expected to result from perceptions of risk, stigmatization, and socially amplified reactions to 'unfortunate events' associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The conceptual underpinnings of risk perception, stigmatization, and social amplification are discussed and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse economic effects. The possibility that intense negative imagery associated with the repository may cause significant harm to Nevada's economy can no longer be ignored by serious attempts to assess the risks and impacts of this unique facility. The behavioral processes described here appear relevant as well to the social impact assessment of any proposed facility that produces, uses, transports, or disposes of hazardous materials

This study investigates the potential impacts of the proposed nuclear waste repository at Yucca Mountain, Nevada, upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. Adverse impacts may be expected to result from perceptions of risk, stigmatization, and socially amplified reactions to "unfortunate events" associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The conceptual underpinnings of risk perception, stigmatization, and social amplification are discussed and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse economic effects. The possibility that intense negative imagery associated with the repository may cause significant harm to Nevada's economy can no longer be ignored by serious attempts to assess the risks and impacts of this unique facility. The behavioral processes described here appear relevant as well to the social impact assessment of any proposed facility that produces, uses, transports, or disposes of hazardous materials.

Dubai: o paraíso hiper-real e paradoxal da indústria do entretenimento

Denize Correa Araujo

2011-01-01

Full Text Available O objetivo geral deste artigo é argumentar que Dubai é um megaexemplo da indústria do entretenimento, podendo ser considerada como paraíso hiper-real. A leitura da cidade, à luz dos conceitos de hiper-realidade e simulacro de Jean Baudrillard e da teoria do espetáculo de Guy Debord, sugere a cultura do superlativo, que começa com o turismo no aeroporto e segue uma rota direcionada aos supereventos e megaprodutos de entretenimento para a sociedade de consumo de luxo. Las Vegas era considerada a “cidadeentretenimento”, com cassinos que simulam diversos pontos turísticos, como Monte Carlo, Veneza, Paris e assim por diante. Agora, o mundo simulado está situado em Dubai, denominada a Nova Las Vegas. O objetivo específico do trabalho é questionar o cenário paradoxal de entretenimento e consumo no contexto de normas religiosas islâmicas rígidas, que divergem dos hábitos dos estrangeiros, dos atrativos dos malls e das praias paradisíacas de Dubai.

Social marketing to plan a fall prevention program for Latino construction workers.

Menzel, Nancy N; Shrestha, Pramen P

2012-08-01

Latino construction workers experience disparities in occupational death and injury rates. The Occupational Safety and Health Administration funded a fall prevention training program at the University of Nevada, Las Vegas in response to sharp increases in fall-related accidents from 2005 to 2007. The grant's purpose was to improve fall protection for construction workers, with a focus on Latinos. This study assessed the effectiveness of social marketing for increasing fall prevention behaviors. A multi-disciplinary team used a social marketing approach to plan the program. We conducted same day class evaluations and follow-up interviews 8 weeks later. The classes met trainee needs as evidenced by class evaluations and increased safety behaviors. However, Spanish-speaking Latinos did not attend in the same proportion as their representation in the Las Vegas population. A social marketing approach to planning was helpful to customize the training to Latino worker needs. However, due to the limitations of behavior change strategies, future programs should target employers and their obligation to provide safer workplaces. Copyright © 2012 Wiley Periodicals, Inc.

Full Text Available El público general cree, como si fuera un dogma religioso, que las pirámides egipcias no fueron las tumbas de los faraones de los Reino Antiguo y Medio porque en ninguna de las cámaras funerarias se ha encontrado nunca una momia. Este estudio compila todos los datos relevantes al respecto y describe brevemente todos los restos humanos encontrados dentro de las pirámides, demostrando la falta de base de esa extendida creencia.As a religious dogma the general public believe that the Egyptian pyramids were not the tombs for the Old and Middle Kingdom pharaohs, because never was a mummy found inside the burial chamber of any of them.

Full Text Available Este artículo se centra en las prácticas basadas en la evidencia y, sobre esta base, hacemos una invitación a que busquemos entre todos cuáles son las mejores prácticas, quién es el profesional más adecuado y qué significa ser una organización eficaz y eficiente. Tanto los profesionales como las organizaciones ofrecen servicios y apoyos que contribuyen a mejorar el bienestar y el crecimiento personal de los usuarios. En el contexto de la discusión sobre las prácticas profesionales y de las organizaciones, indicaré que las mejores prácticas profesionales empiezan con el respeto hacia las personas, el cumplimiento de los estándares y las normas éticas y deontológicas, y la utilización de las prácticas basadas en la evidencia y de la evaluación del efecto y de los resultados conseguidos. Indicaré, asimismo, que las mejores prácticas de la organización empiezan con el compromiso de ser una entidad basada en valores y, a la vez, de ser eficaz y eficiente en la prestación de los servicios y apoyos. Este compromiso de la organización se refleja en el uso de las mejores prácticas, que consisten en la utilización de equipos de alto rendimiento, en el paradigma de los apoyos, en la evaluación de los resultados obtenidos y en la mejora continua de la calidad.Como se observa en la Figura 1, examinaremos cada uno de los componentes de las mejores prácticas profesionales y de las organizaciones. Además, indicaré que, a través de su acción recíproca, las mejores prácticas de los profesionales y de las organizaciones generan un entorno cultural que tiene un efecto directo, no solo en la mejora de los servicios y apoyos que la organización ofrece a los usuarios, sino también en el bienestar y crecimiento personal del personal de la organización, lo cual, a su vez, redunda en un aumento de su eficacia y eficiencia.

Full Text Available A partir de los años 90 las teorías feministas de la tecnología experimentan un optimismo renovado con la aparición de las TIC y el desarrollo de la tercera ola feminista. Sin embargo, la investigación en género y tecnología se ha centrado en estudiar la exclusión de las mujeres de las TIC e, inversamente, las experiencias de las mujeres y sus estrategias para incluirse en las TIC han recibido menos atención. Motivadas por nuestras experiencias tecnoactivistas y la observación de una remarcable presencia de mujeres en ellas, con Donestech, iniciamos un proyecto de investigación sobre los accesos, usos y deseos de las mujeres en las TIC. A través de una investigación ciberfeminista recogimos, analizamos y visibilizamos las experiencias y opiniones de las mujeres en las TIC. Nuestros resultados sugieren que las trayectorias de inclusión y acceso de las mujeres en las TIC son diversas, así como heterogéneos son los usos que hacen de ellas, destacando el rol jugado por Internet en todo ello. Además mostramos que las mujeres en las TIC son curiosas y entusiastas, que quieren empoderarse y compartir el conocimiento. Finalmente, les disgusta y desconfían de las relaciones de poder existentes en los mundos tecnológicos, manteniendo una actitud crítica y creativa hacia las TIC.

The infrared flux method and its use for study of α Boo, μ Her and β Dra; relation to the Vega 1.2-5 μm infrared excess

The effective temperatures of α Boo, μ Her, and β Dra are determined using the infrared flux method. The determinations are based on the high-quality spectrophotometric data obtained from an aircraft by previous authors, the new infrared calibration of Vega obtained from observations made at Tenerife between 1979 and 1983, the use of a Reticon spectrometer to determine the integrated fluxes in the region 370-950 nm, and the use of model atmospheres constructed with the previously developed MARCS code.

Full Text Available Aunque las redes sociales (los SRS, especialmente Facebook se han popularizado entre la juventud, hay algunos alumnos universitarios que no desean participar en ellas. Esta investigación explora las razones subyacentes por las cuales los alumnos universitarios no utilizan las redes sociales. El grupo experimental (n=20 estuvo formado por alumnos de licenciatura de entre 18 y 25 años, seleccionados mediante muestreo intencional. Se recogieron los datos en dos grandes universidades estatales de Turquía. Facebook fue seleccionado para contextualizar esta investigación, por ser una de las redes sociales más populares. Los métodos de investigación cualitativa se emplearon en la recogida y análisis de los datos. Entre las razones principales por las que no utilizan las redes sociales se encuentran su percepción como una pérdida de tiempo, o una herramienta innecesaria; las posibilidades de poder conllevar una adicción; violar las normas de privacidad, compartir información excesiva; e invocar la preocupación parental. Adicionalmente, los resultados indicaron que la mayoría de los alumnos no confió en sus amistades virtuales y que no les gustaba compartir fotografías ni opiniones políticas en línea. El haber identificado las actitudes hacia los SRS de los alumnos nousuarios nos ayudará a entender mejor las percepciones y experiencias individuales relacionadas con estos servicios sociales.

La intangibilidad de las acciones privadas de las personas

Mauricio Maldonado Muñoz

2014-03-01

Full Text Available En este artículo pretendemos acercarnos a una garantía que —siguiendo cierta doctrina— hemos llamado: intangibilidad de las acciones privadas de las personas. Desde una visión que busca ser omnicomprensiva, se analizan las fuentes de las que mana la privacidad y, posteriormente, su contenido y alcances. Sobre todo, se analiza el problema de los límites de la injerencia y regulación estatal, partiendo de una posición que niega las visiones comunitaristas. En general, se trata de conceptualizar a la garantía planteada desde el punto de vista de la libertad, el derecho y las virtudes humanas, los derechos de terceros y la moral pública; concretando su vinculación con otros derechos relacionados con la privacidad. La idea central del presente trabajo consiste en demostrar la transversalidad de la garantía señalada, implicando —en ese proceso— cuestiones trascendentes para la filosofía del derecho, la teoría del derecho y, por supuesto, para el estudio del derecho de los derechos humanos.  

Las relaciones de Podemos con las organizaciones sociales

2015-09-01

Full Text Available El 15M fue el principio del proceso de cambio en España y tiene una trascendencia en el mundo porque, por primera vez desde 1989, un movimiento contestatario al sistema alcanza una repercusión mundial. En consecuencia, todos partidos políticos en España atienden las demandas de este movimiento, bien para impulsar cambios en sus programas que atiendan a sus demandas o para intentar asumir su representación política como hace Podemos. En esta exposición se considera la tradición política de este país y el surgir del 15M, para comentar, después, las críticas a Podemos como heredero del 15M, y terminar con el análisis de su relación con las organizaciones sociales. La exposición se organiza en cinco tiempos que en su conjunto dan una visión poliédrica del problema. El objetivo es tratar de contradecir el escepticismo del Quijote sobre la posibilidad de comprender las razones y las dinámicas de los cambios sociales.

Full Text Available Resumen Este artículo explora el efecto social y económico que causan las políticas de financiamiento orientadas hacia las micro, pequeñas y medianas empresas en el mercado local y regional en Costa Rica. El microcrédito ha sido una valiosa herramienta de desarrollos de las Mipymes en países desarrollados. La experiencia del FIDEICOMISO-IMAS-BANACIO es uno de los más importantes en Costa Rica para apoyar a los pequeños productores localizados en las regiones más vulnerables como el sur, atlántico y norte del país. Este modelo muestra los efectos cuantitativos y cualitativos del microcrédito sobre variables fundamentales como la producción, empleo, ingresos y habilidades humanas. La principal conclusión radica en afirmar que el microcrédito causa efectos positivos en las capacidades competitivas de las Mipymes así como beneficios sociales sobre las familias que han desarrollado microempresas en las regiones más pobres de Costa Rica.   Abstract This paper explores the social and economic effects of financing policies oriented at small and medium size enterprises in the local and regional market in Costa Rica. The microcredit has been and useful tool to develop SMEs in developing countries. The experience of the FIDEICOMISO-IMAS-BANACIO is one of the most important in Costa Rica to support small producers located in vulnerable regions such as South, Atlantic and North among others. This model show quantity and quality effects of the microcredit on essential variables like production, employment, incomes and human skills. The main conclusion claim that microcredit causes positive effects on the competitive skills of SMEs as well as social benefits on some families that have been developing enterprises in poor regions in Costa Rica.

Las ideologias, las ciencias naturales y sus implicaciones en la educacion cientifica

Lozada Roldan, Sandra

Este estudio ausculto las concepciones epistemologicas de los docentes de ciencia del nivel secundario con relacion a las ideologias y las ciencias naturales. Tambien examino las posiciones de los docentes ante asuntos publicos relacionados a la ciencia. Para propositos de este estudio se diseno y se valido el cuestionario con el cual se obtuvieron los resultados. La investigacion es de tipo cuantitativa y se utilizo como diseno la encuesta. El cuestionario se administro en varias actividades de desarrollo profesional para maestros de ciencia. Un total de 78 maestros del nivel secundario respondieron el cuestionario. Para analizar los datos obtenidos se utilizaron estadisticas descriptivas como la distribucion de frecuencia y el porciento. Ademas se establecieron codigos y categorias para describir las posiciones de los maestros ante asuntos publicos relacionados a la ciencia. Los analisis demostraron que entre los docentes participantes de este estudio prevalecen ciertas concepciones epistemologicas adecuadas acerca de las ciencias naturales, a la luz de la literatura consultada. Entre estas concepciones se destacan las siguientes: a) la filosofia materialista de las ciencias naturales, b) la naturaleza tentativa y constructivista del conocimiento cientifico, c) el uso de una metodologia que garantiza cierto grado de objetividad y con el que se justifican y validan los enunciados cientificos y d) la funcion instrumental del conocimiento cientifico. Sin embargo, entre los docentes participantes de este estudio prevalecen ciertas concepciones epistemologicas erroneas acerca de las ciencias naturales, a la luz de la literatura consultada. Entre estas concepciones se destacan las siguientes: a) tendencia inductivista en el que las teorias cientificas comienzan con observaciones que establecen generalizaciones, b) secuencia jerarquica de la metodologia cientifica. Ademas, entre los docentes participantes de este estudio prevalecen concepciones epistemologicas adecuadas

Ana I Molineri

Full Text Available El objetivo de este trabajo fue evaluar el grado de conocimiento que tienen los trabajadores rurales sobre las zoonosis a las que se encuentran expuestos en su trabajo y su asociación con factores socio-demográficos. Se efectuó un estudio observacional transversal basado en la realización de encuestas (N = 110, n = 94, utilizando un cuestionario estructurado. El análisis incluyó c², t de Student y correlación de Pearson y de Spearman. Las zoonosis más conocidas fueron la triquinosis, la rabia y la sarna. En el caso de la brucelosis, la tuberculosis y el carbunco, fueron muy conocidas las especies que las transmiten, pero no así las formas de transmisión. Las enfermedades menos conocidas en ambos sentidos fueron la toxocariasis y la hidatidosis, seguidas por la leptospirosis y la toxoplasmosis. Para todas las zoonosis estudiadas se encontró correlación significativa (p < 0,001 entre el conocimiento de las especies transmisoras y de las vías de transmisión. Aquellos encuestados de sexo masculino, propietarios y residentes de zonas urbanas, casados y de mayor edad y antigüedad fueron quienes presentaron más conocimientos sobre las zoonosis, en general. El conocimiento que tienen los trabajadores rurales acerca de las zoonosis es insuficiente. Sería importante que los veterinarios, en conjunto con las aseguradoras de riesgos del trabajo, difundan la información adecuada entre las personas en riesgo que desarrollan sus tareas en este ámbito.

Las mujeres y los puestos para expatriados en las multinacionales latinoamericanas

Edgar E. Chaves Solano

2009-07-01

Full Text Available Una de los aspectos más importantes del mercado laboral mundial en la última mitad del siglo XX ha sido la tasa de participación cada vez mayor de las mujeres en puestos gerenciales. Sin embargo, es evidente, de acuerdo a la investigación existente, que las mujeres no progresan en los puestos de dirección internacional en las mismas tasas que sus homólogos masculinos. Investigaciones anteriores ha estimado que sólo el 3 % de los administradores expatriados son mujeres. Se argumenta que las mujeres en puestos de dirección internacional tienen que superar las barreras abiertas y encubiertas en sus organizaciones antes de ser tomadas en cuenta para asignaciones internacionales. Los estudios mencionados se refieren a los países desarrollados. En el caso de las corporaciones latinoamericanas no se han encontrado estudios teóricos ni empíricos que arrojen luz sobre el tema de la mujer expatriada. El objetivo del presente trabajo es obtener razones y mitos sobre la asignación de las mujeres como expatriadas en los países desarrollados para, en un posterior estudio determinar si esas razones son validas o no con las mujeres expatriadas de las corporaciones de América Latina y que estos resultados ayuden a tomar mejores decisiones a los gerentes cuando tengan que llenar un puesto en el exterior

Full Text Available Durante muchas décadas la enseñanza y la práctica de las Relaciones Públicas en Brasil y demás países de América Latina utilizaron como referencia central un abordaje norteamericano y, en menor escala europea. Tal comportamiento llevó los profesionales a adoptar valores y modelos importados como referencia para nuestro comportamiento organizacional. Desde la década de 1990, con el fenómeno de la globalización y el avance de la tecnología, las Relaciones Públicas pasaron a ejercer un papel más estratégico y menos táctico. Hoy, las Relaciones Públicas son una profesión necesaria para el posicionamiento de las organizaciones en el mercado y también como responsable por las relaciones ente las organizaciones y sus stakeholders. / For many decades the teaching and practice of Public Relations in Brazil and in neighboring Latin American nations have largely relied on a North American and - to a lesser degree - a European perspective. This led our professionals to adopt values and imported models as the main reference for our organizational behavior. Beginning during the 1990’s and a result of globalization and technological development, Public Relations began to behave in a more strategic and less tactical manner. Today, Public Relations is a profession that is required for the positioning of organizations in the marketplace, which is also responsible for the relations between organizations and their stakeholders.

José Eugenio Hernández Hernández

1999-05-01

Full Text Available Los pequeños productores agrícolas del municipio de La Vega, ubicado en la región del Guáliva, en el departamento de Cundinamarca, al igual que la mayoría de los productores campesinos del país, han estado viendo seriamente afectadas sus cosechas de maíz, fríjol y en general de granos básicos, a causa del ataque de diferentes agentes biológicos considerados plagas de los granos almacenados tales como insectos, microorganismos, pájaros y roedores, debido al desconocimiento de las técnicas apropiadas para el manejo postcosecha de estos productos y a la carencia de sistemas seguros de almacenamiento y conservación de los mismos. Con la cofinanciación del Programa Nacional de Transferencia de Tecnología, PRONATTA, del Ministerio de Agricultura y Desarrollo Rural, el presente proyecto se planteó para su desarrollo durante un período inicial de doce meses, en tres veredas del municipio, las cuales fueron seleccionadas tomando como criterios básicos la existencia de una problemática sentida en aspectos de manejo y conservación de los granos, así como el interés de los agricultores por encontrar alternativas de solución al problema y participar en su implementación. Posteriormente, y debido a los resultados positivos alcanzados, el proyecto fue extendido por solicitud de los agricultores de la región, a otras tres veredas con similar problemática, y al final se alcanzó un cubrimiento total de sesenta familias de pequeños productores en seis veredas de ésta población, para un tiempo total de ejecución de 20 meses. Con la participación activa de los agricultores en cada una de las etapas del proyecto, se validó para las condiciones socioeconómicas y agroecológicas de la región, un modelo metodológico de transferencia de tecnología para el manejo postcosecha de granos básicos a nivel de pequeños agricultores, el cual había sido previamente implementado con éxito en zonas de economía campesina de algunos municipios

New World monkeys (platyrrhines) are a diverse part of modern tropical ecosystems in North and South America, yet their early evolutionary history in the tropics is largely unknown. Molecular divergence estimates suggest that primates arrived in tropical Central America, the southern-most extent of the North American landmass, with several dispersals from South America starting with the emergence of the Isthmus of Panama 3-4 million years ago (Ma). The complete absence of primate fossils from Central America has, however, limited our understanding of their history in the New World. Here we present the first description of a fossil monkey recovered from the North American landmass, the oldest known crown platyrrhine, from a precisely dated 20.9-Ma layer in the Las Cascadas Formation in the Panama Canal Basin, Panama. This discovery suggests that family-level diversification of extant New World monkeys occurred in the tropics, with new divergence estimates for Cebidae between 22 and 25 Ma, and provides the oldest fossil evidence for mammalian interchange between South and North America. The timing is consistent with recent tectonic reconstructions of a relatively narrow Central American Seaway in the early Miocene epoch, coincident with over-water dispersals inferred for many other groups of animals and plants. Discovery of an early Miocene primate in Panama provides evidence for a circum-Caribbean tropical distribution of New World monkeys by this time, with ocean barriers not wholly restricting their northward movements, requiring a complex set of ecological factors to explain their absence in well-sampled similarly aged localities at higher latitudes of North America.

Full Text Available En el aprendizaje de segundas o terceras lenguas se debe destacar el importante papel que juegan las actitudes lingüísticas. En este artículo, en primer lugar nos acercamos conceptualmente a este tipo de actitudes para después centrarnos en cómo los factores actitudinales y motivacionales influyen en el aprendizaje lingüístico. De acuerdo con lo expuesto y siguiendo la terminología de Lambert, en segundo lugar nos detenemos en cómo el tipo de motivación que tienen los sujetos (instrumental o de integración determina su grado de competencia lingüística y en cómo las actitudes presentes en la familia influyen en las actitudes que desarrollan estos sujetos hacia las otras comunidades lingüísticas. Repasamos también el debate existente entorno a toda esta temática, y subrayamos las principales variables que pueden originar o cambiar las actitudes lingüísticas, realzando el papel de la familia, la escuela y los mass media. Finalmente, resumimos brevemente un estudio centrado en las actitudes ante las lenguas de los escolares de origen inmigrante en Cataluña.

Full Text Available El mercado laboral tecnológico, donde las mujeres son minoría, representa una oportunidad para el empleo en España. Este trabajo analiza los datos de la Encuesta de Población Activa (EPA respecto a la población ocupada en el sector tecnológico. En primer lugar, se analiza la segregación de género de la población ocupada según sectores económicos y, en segundo lugar, las características de empleo de las mujeres ocupadas en el sector tecnológico. Los resultados indican que las mujeres disponen de buenas expectativas laborales en este sector, pero también indican que sufren un mayor riesgo de sobrecualificación, lo que sugiere la persistencia de factores de discriminación. Por último, las mujeres expresan mayor preocupación que sus colegas hombres respecto a las excesivas jornadas laborales, lo que plantea la necesidad de afrontar un cambio estructural en las organizaciones.

Semler, M.O.; Sensintaffar, E.L. [National Air and Radiation Environmental Laboratory, Montgomery, AL (United States)

1993-12-31

The Office of Radiation and Indoor Air, U.S. Environmental Protection Agency (EPA), operates six radon exposure chambers in its two laboratories, the National Air and Radiation Environmental Laboratory (NAREL) in Montgomery, Alabama, and the Las Vegas Facility, Las Vegas, Nevada. These radon exposure chambers are used to calibrate and test portable radon measuring instruments, test commercial suppliers of radon measurement services through the Radon Measurement Proficiency Program, and expose passive measurement devices to known radon concentrations as part of a quality assurance plan for federal and state studies measuring indoor radon concentrations. Both laboratories participate in national and international intercomparisons for the measurement of radon and are presently working with the National Institute of Standards and Technology (NIST) to receive a certificate of traceability for radon measurements. NAREL has developed an estimate of the total error in its calibration of each chamber`s continuous monitors as part of an internal quality assurance program. This paper discusses the continuous monitors and their calibration for the three chambers located in Montgomery, Alabama, as well as the results of the authors intercomparisons and total error analysis.

Nutrition training for chefs: taste as an essential determinant of choice.

Science.gov (United States)

Palmer, J; Leontos, C

1995-12-01

The primary objective of Project LEAN (Low-fat Eating for Americans Now), a social marketing initiative of the Henry J. Kaiser Family Foundation, is to help Americans reduce their fat intake to less than 30% of total energy. In Las Vegas, Nev, one of the 10 community sites selected to implement this goal, Las Vegas LEAN acted to change the food environment for restaurant patrons. This program empowered chefs to use their culinary expertise in developing good-tasting, low-fat menu items. The literature shows that consumers, despite verbalizing health concerns, choose food on the basis of taste. This ambivalence between belief and behavior demonstrates the need for innovative culinary techniques to develop food dishes that consumers will not only accept, but will enjoy and order repeatedly. Entrepreneurial dietitians, thus, have an opportunity to market nutrition skills to restaurants and hotels wishing to implement low-fat cuisine with good taste. Our intervention demonstrated that nutrition education for chefs is the key to long-term and successful menu changes. If taste is what consumers are seeking in low-fat items, and improved taste will finally get ambivalent consumers to change their eating behavior, enlisting the expertise of chefs is key.

Disruption of ecosystem processes in western North America by invasive species

Full Text Available Many ecosystems of western North America have been dramatically changed by non-native species. Here, we review ecological impacts of 56 plant, animal, fungus, and protist species that were brought to this region by humans. We discuss characteristics of invasive species that can lead to major ecosystem impacts, and explore how invasive species alter many different attributes of ecosystems. Specifically, we include examples of invasive species that affect geomorphology, fire regimes, hydrology, microclimate, atmospheric composition, nutrient cycling, and productivity. Finally, we review the direct consequences of biological invasions for some native species. We summarize examples from this paper in Appendix 1. Our examples illustrate how, as invasive species have become dominant across large areas of western North America's grassland, shrubland, dune, riparian, and estuarine ecosystems, the properties and functioning of these systems have changed. To date, some systems in this region, such as its forests, remain relatively unaffected by invasive species. However, recent attacks of forest pathogens highlight the potential vulnerability of these ecosystemsMuchos ecosistemas de Norteamérica occidental han cambiado dramáticamente a causa del efecto producido por especies no autóctonas.

Introducción

El estudio del sistema nervioso considera entre múltiples conexiones, aquéllas de carácter bioquímico que se median a través de sustancias elaboradas por las neuronas y que reciben la denominación de neurotransmisores’, dichas sustancias se vierten en las zonas de resquicio neuromuscular, neuroneuronal o neuroglandular, para modificar las condiciones de membrana y permitir la continuidad de los potenciales de acción (por creación de nuevos potenciales en las células subsiguientes, de la neurona hacia el órgano blanco.

La integridad de los diversos elementos de la “zona de unión funcional” o sinapsis, asegura la adecuada comunicación entre el sistema nervioso y la mayoría de los elementos restantes del organismo humano.

Las alteraciones de los elementos de las sinapsis, conllevan a la génesis de estados variables fisiológicos y patológicos somáticos, psicosomáticos o psíquicos, inconsecuentes con el estado de homeostasis.

Las moléculas que se vierten en las hendiduras sinápticas, sirven, por tanto, de transductoras para efectos elementales (como los reflejos y en las estrategias complejas (como los de la actividad intelectual.

Antecedentes

Ya desde los tiempos de Galeno, se sabía que los nervios eran los responsables de la rápida comunicación entre el cuerpo y el cerebro; el estudio de las sinapsis nos remonta de manera indirecta a
1791, fecha en la que Luigi Galvani, descubrió en sus experimentos con ancas de ranas, que entre los eventos eléctricos y los ocurridos en los nervios, existía una relación evidente (28,37,45’, los experimentos de Galvani se han refinado con el paso del tiempo, en nuestro siglo por ejemplo, el desarrollo del osciloscopio de rayos catódicos combinado con un amplificador potente, ha permitido medir las débiles y variables corrientes bioeléctricas de los

La dinámica de las relaciones sociales que articulan a las economías campesinas en Colombia es el objeto de este articulo. Para explicar la importancia de esta forma de producción en el mundo rural se contemplan dos dimensiones de análisis: la dimensión regional, que busca dar cuenta de las especificidades de la estructura agraria colombiana. Aquí se consideran los casos particulares de la comarca de la Región de Los Andes Orientales (Mílga y Duitama y dos comarcas de la región Valle-Tolima-Huila (Cali y Tuluá. En segundo lugar se considera la dimensión histórica, la cual permite apreciar las transformaciones sufridas por las economías campesinas en cada espacio regional. El rango histórico escogido considera los últimos cincuenta años dado que es en este periodo donde se observan los procesos más significativos de penetración del capital en el campo colombiano. Se presentan los elementos cualitativos más relevantes de los procesos acaecidos en las economías campesinas de las comarcas arriba mencionadas presentando, en segundo lugar, una síntesis interpretativa de los factores más significativos que han influenciado estas transformaciones. Se concluye fijando una posición en referencia a los debates descritos y, sugiriendo algunos puntos que buscan aportar a la creación de un nuevo contexto económico y social que faculte el desarrollo de las economías campesinas en Colombia.

Las instituciones paternalistas de los empresarios (vivienda, asistencia sanitaria, tiendas con descuento, etc. se estudian en términos de disciplina, formación para la producción y control político de la fuerza de trabajo. Se intenta demostrar que hay una continuidad genealógica entre los propósitos de las comunidades utópicas de principios del siglo XIX y las comunidades de trabajadores creadas por los empresarios en la segunda mitad de dicho siglo. Se indica cómo dicha continuidad sólo pudo producirse debido a la revisión y distorsión que las teorías de los socialistas utópicos sufrieron por parte de sus seguidores.

Full Text Available En este artículo se examina el efecto del outsourcing en el desempeño de las exportaciones de las empresas. El análisis se basa en las teorías de los negocios internacionales y el punto de vista de los recursos y la economía de los costos de transacción, según los cuales el outsourcing en el extranjero ayuda a las empresas -directa o indirectamente- a exportar más, a reducir sus costos de producción y a aumentar la flexibilidad de la empresa; además, puede proporcionar nuevos recursos y conocimientos del mercado. Sin embargo, el impacto del outsourcing internacional depende de los recursos y las capacidades de las empresas para gestionar una red de proveedores extranjeros y para absorber los conocimientos extranjeros. Usando una base de datos de alrededor de mil empresas de fabricación en México de 2007, se encontró que las operaciones de outsourcing en el extranjero aumenta el rendimiento de la exportación, los efectos son más fuertes en los mercados de exportación de donde las empresas importan los bienes intermedios. Los resultados también muestran que el tamaño de la empresa, la organización de las importaciones intrafirma y la experiencia en la exportación moderan los efectos del outsourcing de manera positiva. Estos resultados tienen implicaciones para las empresas y los políticos responsables del diseño de políticas.

Se utilizó la clasificación de Knight y North para la selección de las variantes de tratamiento, determinándose las variables edad, sexo, clasificación, terapéutica quirúrgica, complicaciones y resultados posoperatorios. Se observó un predominio del sexo masculino con el 75,7 %, y dicha cirugía se realizó con mayor frecuencia entre los 25-34 años (34,3 %. La clase III de Knight y North fue la más frecuente (45,6 %, seguida por la II y IV, con el 31,6 y 10,1 %, respectivamente. Basados en esta clasificación y teniendo en cuenta el grado de inestabilidad posreducción esperado, se seleccionó adecuadamente la variante terapéutica a emplear en el 98,8 % de los casos. Se llega a la conclusión de que la incidencia de fracturas orbitocigomáticas es alta, y dentro de ellas, la clase III de Knight y North es la más frecuente.

Assessment of multiple sources of anthropogenic and natural chemical inputs to a morphologically complex basin, Lake Mead, USA

Science.gov (United States)

Rosen, Michael R.; Van Metre, P.C.

2010-01-01

Lakes with complex morphologies and with different geologic and land-use characteristics in their sub-watersheds could have large differences in natural and anthropogenic chemical inputs to sub-basins in the lake. Lake Mead in southern Nevada and northern Arizona, USA, is one such lake. To assess variations in chemical histories from 1935 to 1998 for major sub-basins of Lake Mead, four sediment cores were taken from three different parts of the reservoir (two from Las Vegas Bay and one from the Overton Arm and Virgin Basin) and analyzed for major and trace elements, radionuclides, and organic compounds. As expected, anthropogenic contaminant inputs are greatest to Las Vegas Bay reflecting inputs from the Las Vegas urban area, although concentrations are low compared to sediment quality guidelines and to other USA lakes. One exception to this pattern was higher Hg in the Virgin Basin core. The Virgin Basin core is located in the main body of the lake (Colorado River channel) and is influenced by the hydrology of the Colorado River, which changed greatly with completion of Glen Canyon Dam upstream in 1963. Major and trace elements in the core show pronounced shifts in the early 1960s and, in many cases, gradually return to concentrations more typical of pre-1960s by the 1980s and 1990s, after the filling of Lake Powell. The Overton Arm is the sub-basin least effected by anthropogenic contaminant inputs but has a complex 137Cs profile with a series of large peaks and valleys over the middle of the core, possibly reflecting fallout from nuclear tests in the 1950s at the Nevada Test Site. The 137Cs profile suggests a much greater sedimentation rate during testing which we hypothesize results from greatly increased dust fall on the lake and Virgin and Muddy River watersheds. The severe drought in the southwestern USA during the 1950s might also have played a role in variations in sedimentation rate in all of the cores. ?? 2009.

Hydrogen-Enhanced Natural Gas Vehicle Program

Energy Technology Data Exchange (ETDEWEB)

Hyde, Dan; Collier, Kirk

2009-01-22

The project objective is to demonstrate the viability of HCNG fuel (30 to 50% hydrogen by volume and the remainder natural gas) to reduce emissions from light-duty on-road vehicles with no loss in performance or efficiency. The City of Las Vegas has an interest in alternative fuels and already has an existing hydrogen refueling station. Collier Technologies Inc (CT) supplied the latest design retrofit kits capable of converting nine compressed natural gas (CNG) fueled, light-duty vehicles powered by the Ford 5.4L Triton engine. CT installed the kits on the first two vehicles in Las Vegas, trained personnel at the City of Las Vegas (the City) to perform the additional seven retrofits, and developed materials for allowing other entities to perform these retrofits as well. These vehicles were used in normal service by the City while driver impressions, reliability, fuel efficiency and emissions were documented for a minimum of one year after conversion. This project has shown the efficacy of operating vehicles originally designed to operate on compressed natural gas with HCNG fuel incorporating large quantities of exhaust gas recirculation (EGR). There were no safety issues experienced with these vehicles. The only maintenance issue in the project was some rough idling due to problems with the EGR valve and piping parts. Once the rough idling was corrected no further maintenance issues with these vehicles were experienced. Fuel economy data showed no significant changes after conversion even with the added power provided by the superchargers that were part of the conversions. Driver feedback for the conversions was very favorable. The additional power provided by the HCNG vehicles was greatly appreciated, especially in traffic. The drivability of the HCNG vehicles was considered to be superior by the drivers. Most of the converted vehicles showed zero oxides of nitrogen throughout the life of the project using the State of Nevada emissions station.

LAS NORMAS JURÍDICAS Y LAS POLÍTICAS PÚBLICAS SOBRE BOSQUES CULTIVADOS EN LAS REGIONES DEL CENTRO Y DE PATAGONIA EN ARGENTINA

Full Text Available El eje central de este trabajo es analizar el nivel de desarrollo de las normas jurídicas, de las políticas públicas, y de la idoneidad de las autoridades de aplicación sobre bosques cultivados, en las regiones del Centro y de la Patagonia en Argentina. Se trata de una investigación de carácter exploratorio, donde se aplicó el método de la hermenéutica jurídica y los indicadores ambientales PER. Se puede concluir que los niveles de desarrollo normativo de las provincias no son uniformes, y que la mayoría de las normas jurídicas y de las políticas públicas tienden a establecer incentivos económicos para aprovechar el efecto del mercado, sin orientarse hacia una protección integral de los ecosistemas boscosos, y que las autoridades de aplicación en su mayoría no son técnicamente adecuadas para eso.

Full Text Available A través de la historia los administradores se han dedicado a dirigir las empresas sin tener en cuenta que su componente central y relevante es el hombre, a quien se le ha relegado al plano de recurso, olvidando su humanidad y su complejidad y el hecho de que se compone de elementos racio nales y emotivos que lo hacen único. La motivación principal del hombre es la búsqueda de la felicidad, y puede conseguirla en el entorno empresarial siempre y cuando las organizaciones estén dirigidas por líderes conscientes de la importancia de los seres humanos en las mismas. A pesar de lo anterior, el rol de los administradores se ha destacado por el énfasis en el logro de los objetivos de la empresa y la falta de apoyo al crecimiento personal de los trabajadores. Es el momento de comenzar a cuestionarnos nuestro verdadero papel como rectores de destinos humanos en las organizaciones y de preparar a las nuevas generaciones de administradores para el rescate de la importancia del ser humano al interior de éstas.

Full Text Available The ruins and the shadows of Manderley explores possible reciprocal interpretative relations between Daphne du Maurier’s novel Rebecca and Alfred Hitchcock’s cinematic version. Some of the relevant aspects considered here are: the treatment of the Derridean “ruins of memory” within the novel and within Hitchcock himself, the differentiation and the confrontation of the protagonist as outsider vis á vis the world of Manderley’s insiders, the iconic and symbolic values of the literary text and its filmic visualization, and the ethical positions implied by the choice or rejection of certain narrative devices in both works.

Las ruinas y las sombras de Manderley aborda posibles relaciones interpretativas recíprocas entre la novela de Daphne du Maurier Rebecca y la película homónima de Alfred Hitchcock.

Full Text Available El mundo del marketing ha cambiado significativamente en los últimos años debido, en gran parte, al surgimiento del Internet como herramienta de investigación y búsqueda. Este se ha constituido en uno de los elementos  tecnológicos  más significantes  dentro  del ambiente empresarial. La facilidad que el Internet ofrece a las empresas para acceder a información y proveer datos relacionados  a las transacciones  de negocio,  habilita a dichas empresas  a lograr mayores resultados en su estrategia de marketing. Independientemente del tamaño de la empresa, el Internet ha permitido que estas hayan cambiado la forma de acceder y proveer información.  Este, además,  ha sentado nuevas pautas en la manera de comprar, buscar, recopilar  y aprender.  En este  estudio,  realizado  en  la  ciudad  de  Manta  -  Ecuador,  los resultados demuestran que todas las pymes están conectadas al Internet y solo 3 de cada 10 tienen departamento de marketing  y no emplean adecuadamente  las herramientas que el marketing y las TIC les proporcionan   para alcanzar un mejor desarrollo empresarial. La investigación   realizada   fue cualitativa,   usándose   la   técnica   de   la   encuesta    para  el levantamiento de la información. Por tanto, puede afirmarse que no existe una cultura de marketing en las pymes de la ciudad de Manta - Ecuador. Palabras clave: Generalidades, marketing, publicidad, otros.

Full Text Available Se trata de responder la pregunta: ¿qué función ejercen las matemáticas en las ciencias económicas? Se hace, entonces, un recorrido por las etapas del conocimiento humano: la mítica, la intuitiva, la experimental y la racional y, luego, se describe el proceso de elaboración de un modelo económico abstracto en el que las matemáticas juegan un papel fundamental so pena de que el economista quiera construir una ciencia de juguete. Para apoyar la idea de que las matemáticas son importantes y necesarias en la economía, se presenta un resumen de una encuesta dirigida por Paul Samuelson a economistas notables, publicada en 1954. Los resultados apuntan, precisamente, a señalar que las matemáticas tienen una función fundamental en las Ciencias Económicas.

Las emociones positivas y la empatía como promotores de las conductas prosociales e inhibidores de las conductas agresivas

Full Text Available Resumen El objetivo del presente artículo es analizar qué proporción de variancia de la prosocialidad y de la agresividad predice las emociones positivas (alegría y gratitud, serenidad y satisfacción personal, la empatía (toma de perspectiva y preocupación empática y la autoeficacia social. Dado que existen abundantes investigaciones que muestran que existen diferencias significativas en las conductas prosociales y la agresividad en función del sexo es que estos análisis se realizaron por separados en niños y niñas. La muestra estuvo compuesta por 221 niños, de ambos sexos (42.2 % de varones, de 10 a 13 años (M = 11.45, DE = .80, de clase social media, que concurrían a escuelas primarias de la ciudad de Buenos Aires, Argentina. Los resultados indican que tanto la empatía como las emociones positivas se encuentran involucradas en la predicción de la conducta prosocial, tanto en los niños como en las niñas. Sin embargo, parece claro que en el caso de los niños la empatía tiene una mayor fuerza predictiva que las emociones positivas, a diferencia de las niñas donde ambas variables parecen compartir similar potencia. Por otro lado, la autoeficacia social predice la conducta prosocial solo en la niñas. Por último, los resultados indicaron que tanto la empatía como las emociones positivas inhiben la conducta agresiva solo en las niñas.

The effects of regional economic integration in Europe of the pattern north-north and north-south

Directory of Open Access Journals (Sweden)

Antevski Miroslav

2007-01-01

Full Text Available This paper examines the effects of regional economic integration in Europe, especially the North-North and North-South integration patterns, and how the benefits and costs of integration are divided between countries. Outcomes depend on: comparative advantages, factor endowments, factor intensities, competitive advantages, FDI flows, transfers of technology, knowledge spillovers, economies of scale, transport costs, industry/GDP ratios, and agglomeration forces. The North-North integration between high income countries tends to lead to convergence of country incomes. Contrary, the South-South integration between low income countries causes divergence. Low income countries are likely to be better served by the North-South integration.

Full Text Available La localización de las sedes de las grandes empresas {headquarter es un tema de interés socioterritorial por cuanto implica relaciones de poder y dependencia entre territorios, con tendencia progresiva a la mundialización. El objetivo principal es detectar algunos de los factores socioterritoriales que intervienen en su localización, sobre la hipótesis de la importancia que tienen los entornos metropolitanos y de capitalidad. El análisis empírico se plantea al nivel de los centros de decisión de las grandes empresas y al nivel de los centros de decisión subsidiaria en naciones secundarias (España. Así la escala mundial de las grandes empresas multinacionales se contrastará con lo que ocurre dentro de un territorio secundario en las lógicas de distribución de las sedes primarias y subsidiarias. Se toma como base las 500 grandes empresas mundiales (Fortune, 2005 y las 1000 mayores empresas en España para los territorios secundarios. La conclusión es que la concentración territorial de poder político, poder económico y vinculación internacional -por este orden de importancia-, son los tres factores fundamentales que explican las decisiones de localización tanto de sedes centrales como subsidiarias, condiciones que de forma casi exclusiva se dan en las áreas metropolitanas, y con especial significación en las capitales de Estado

San Isidro, de labrador medieval a patrón renacentista y barroco en la Villa y Corte

Directory of Open Access Journals (Sweden)

Fernández Montes, Matilde

2001-06-01

Full Text Available The author discusses the evolution of the portrayal of Madrid's patron saint, Isidre, from the peasant holy man working his first posthumous miracles in the late 13^th century to the canonized saint of the 17^th century. On the one hand, hagiographers transformed and completed his life and miracles in order to fit them into the contemporary model of sainthood and, at the same time, meet society's expectations of the saint —especially those of Madrid's oligarchy, who monopolized the cult. On the other hand, because of Lope de Vega's portrayals of Isidre, the saint became very popular among the lower classes in the countryside as well as in the city.

Se estudia la evolución que San Isidro sufre desde sus primeros milagros póstumos, de finales del siglo XIII, cuando aparece como un santo de carácter agrícola, hasta llegar a su canonización en el XVII. Su vida y milagros, por una parte, son transformados y completados por los hagiógrafos para ajustarse al modelo de santidad y las demandas de la sociedad del momento, especialmente por la oligarquía madrileña que monopolizaba su culto, mientras que por otra, gracias a las versiones de Lope de Vega, se acerca y extiende el personaje entre las clases populares, tanto urbanas como rurales.

Three important observations recorded in the energetic particle data secured at Halley's comet during March 1986 are reviewed. These include (a) quasi periodic variations of cometary ion fluxes observed inbound and outbound by both the EPONA instrument aboard Giotto and by the Tunde-M instrument aboard Vega 1. A possible explanation of the results in terms of a spin modulation of the outgassing rate of the nucleus is discussed; (b) by combining the EPONA data with JPA-IIS data it is possible to infer that the ion fluxes measured at encounter by EPONA were of the water group. These particles displayed energies in excess of those attained by the pick-up process acting alone. Comparisons between energy spectra prepared using the composite observational data and, corresponding, theoretically derived plots suggest that, downstream of the shock (inbound), stochastic (second-order-Fermi) acceleration may have contributed to energizing the particles; (c) large fluxes of electrons (E>300keV) and ions (E>3.5 MeV) were unexpectedly recorded by EPONA in the magnetic cavity. The observed enhancements (up to approximately three orders of magnitude) appear to be cometary in origin.

2014-01-01

En las pequeñas empresas aún perdura una gran cantidad de trabajo no registrado realizado mayoritariamente por las mujeres de la familia. Ello atiende a un doble proceso de invisibilidad: primero, por la neutralidad/naturalidad que se asigna a las aportaciones de las mujeres en el ámbito familiar, motivada por el rol que se les ha impuesto históricamente. Y segundo, por la informalidad que suele caracterizar a las ayudas o colaboraciones familiares en las empresas como mecanismo para external...

Las artes de leer e interpretar las hojas de coca

Full Text Available En este artículo quisiera hablar sobre un oficio secreto, subterráneo, clandestino, que es el arte de leer e interpretar las hojas de coca en espacios marginales del valle de Salta. Muestro en estas páginas las diferentes formas y modos en que la coca es utilizada por la población local, diversa y heterogénea, donde tradiciones indígenas ancestrales se manifiestan en prácticas concretas que rozan los límites entre la magia y la terapia. Presto especial interés, a partir del trabajo de campo realizado, a aquellas personas que manejan estas artes de leer las hojas de coca, las cuales en los casos analizados fueron adquiridas a partir de un ritual de paso, que fue el haber sido “tocado por el rayo”. Me interesa particularmente trabajar con estos hombres y mujeres, cuyo arte de hacer con coca es equiparable a las “maneras de hacer”. Estas maneras de hacer con la coca ritual no están visibilizadas y son subterráneas, marginales y silenciosas, en este artículo se pretende dar cuenta de estas prácticas con coca y sus dinámicas relaciones inter e intra comunales. Palabras-claves: Artes; maneras de hacer; coca; ritual.

Full Text Available Las Tablas de Daimiel National Park is a semiarid wetland that exhibits a high biodiversity but is suffering an inexorable eutrophication process. The study of the phytoplankton in this wetland is interesting because of its hydrological fluctuations (drought period until 1996 and its trophic condition. This papers shows the taxonomy, dynamic, and ecology of microalgae in five áreas of the Park from 1996 to 1998, which allow comparisons to be made between the present state and the 1992-1993 period. Twelve taxa of Cyanophyta, 4 of Dynophyceae, 8 of Cryptophyceae, 5 of Chrysophyceae and one of Xanthophyceae were found. Almost all species have been already cited in Spain and are typical for eutrophic environments. Cyanophyceae and Cryptophyceae were the most important groups (Planktothrix agardhii, Anabaenopsis elenkinii, Cryptomonas erosa as the most common algae. Moreover, oscillatorial Cyanophyceae (in 1992 have been replaced by N-fixing nostocal ones, related to the high level of pollution found in recent years.El Parque Nacional Las Tablas de Daimiel es un humedal semiárido, importante reserva de biodiversidad que, sin embargo, está sufriendo un inexorable proceso de eutrofización. Su estado trófico, así como los cambios hidrológicos (sequía hasta 1996, hacen especialmente interesante el estudio de su microflora. Por ello, se ha llevado a cabo este trabajo sobre las poblaciones fitoplanctónicas en cinco puntos del Parque desde 1996 a 1998, que permite además la comparación con su estado en 1992-1993. Se encontraron 12 táxones de Cyanophyta, 4 de Dynophyceae, 8 de Cryptophyceae, 5 de Chrysophyceae y uno de Xanthophyceae. Casi todas las especies están citadas en España y son propias de ambientes eutróficos. Los grupos mejor representados fueron las cianobacterias y criptofíceas (Planktothrix agardhii, Anabaenopsis elenkinii y Cryptomonas erosa fueron las especies más conspicuas.

2009-01-01

Full Text Available Los momentos de externalización de los conflictos permiten observar cómo la protesta se vincula con la "puesta-en-escena" de la construcción- selección de recursos expresivos y con las huellas que hacen posible rastrear un plus en las demandas entabladas. El presente artículo tiene como objetivo reconstruir las conexiones en tre recursos expresivos, "estéticas-en-las-calles" y prácticas heterodoxas. La estrategia que seguimos aquí es posible de ser esquematizada del siguiente modo: 1 se discuten las características de las relaciones entre expresividad, crisis y política; 2 se reconstruyen las escenas-postales de la ciudad de Córdoba, Argentina, a través de los recursos expresivos de las acciones colectivas; y 3 se sintetizan algunos "juegos del lenguaje" asociados a dichas postales. Se finaliza abogando por la necesidad de profundizar los análisis de las acciones colectivas que incluyan los recursos expresivos como un elemento central para superar un mero análisis desde las demandas de las mismas.

Full Text Available Este trabajo indaga sobre la incidencia de las entidades representativas del cooperativismo argentino en las políticas públicas contemporáneas. Se presenta un estudio de caso de las dos más importantes cooperativas de tercer grado del país, se analizan sus metas y estrategias en las interacciones con las dependencias estatales. Los resultados de las acciones de los actores definen metas y estrategias que pueden ser convergentes y/o divergentes. Se concluye que los vínculos que han construido las confederaciones seleccionadas con el Estado presentan características de complementación y cooperación en términos generales. Asimismo, la facultad de las organizaciones estudiadas para incidir en la definición de las políticas públicas resulta no solamente de los recursos propios, sino, principalmente, de las oportunidades políticas y la capacidad de establecer alianzas inter-actorales mediante estrategias colectivas.

Full Text Available El propósito de esta investigación fue aplicar un test que mida las distintas inteligencias múltiples en niños(as de dos distintas escuelas, para así valorar si existe diferencia entre el modelo pedagógico academicista (enfoque tradicional establecido por el Ministerio de Educación Pública y el modelo pedagógico cognitivo (MPC (enfoque constructivista. En este estudio participaron 29 niños y 20 niñas, con edades entre los 8 y 12 años, pertenecientes a dos distintas escuelas públicas de Heredia (Escuela Laboratorio y Escuela de San Isidro. El instrumento que se utilizó fue un Test de Inteligencias Múltiples para niños(as en edades escolares (Vega, 2006, el cual consta de 15 ítems, subdivididos en siete categorías: lingüística, lógico-matemática, visual, cinestésica, musical, interpersonal e intrapersonal. Para el análisis de datos se utilizó la estadística descriptiva y la estadística inferencial (ANOVA de dos vías. Se encontraron diferencias significativas en la inteligencia lingüística (F: 9,47; p < 0,01 entre escuelas MPC (3,24±1,24 puntos y academicista (2,31±1,10 puntos, asimismo se encontraron diferencias entre sexo (F: 5,26; p< 0,05, mujeres (3,25±1,02 puntos y hombres (2,52±1,30 puntos. Además, en la inteligencia musical se encontraron diferencias estadísticamente significativas entre sexo (F: 7,97; p < 0,05. Se puede concluir que los modelos pedagógicos de enseñanza de los centros educativos públicos de Costa Rica deben actualizarse de acuerdo a las nuevas tendencias educativas.

Unificar las ciencias del deporte

Full Text Available El deporte no es solo un fenómeno social de nuestro mundo, sino que también es un campo privilegiado para el estudio del comportamiento social y humano. Durante las últimas décadas, se ha producido un enorme crecimiento y especialización de las ciencias del deporte y el lema del 18º Congreso del European College of Sport Sciences (ECSS “Unificar las ciencias del deporte” representa desafiar este proceso de fragmentación. El lema conlleva un cambio de la especialización a la integración, de una concepción de los sistemas vivos basada en la teoría de la información y la ingeniería a una de base biológica, de la investigación multidisciplinaria a la transdisciplinaria. Pero aparece una pregunta: ¿es posible integrar las áreas fragmentadas y facilitar la transferencia de los principios explicativos teóricos, técnicas y perspectivas metodológicas entre disciplinas? En el marco de las contribuciones hechas en el congreso, este artículo tiene como objetivo introducir enfoques científicos ya extendidos en los ámbitos de la física, la química, la biología (incluyendo las ómicas y las ciencias sociales, y que centradas en las interacciones dinámicas complejas de los componentes sistémicos (proteínas, células, organismos, grupos, sociedades, revelan principios explicativos generales que contribuyen a la unificación del conocimiento. Intentamos animar a las personas interesadas en las ciencias del deporte a percibir nuevas formas de investigación y a complementar, sin sustituirlos, los enfoques dominantes, con la esperanza de que ir de las partes al todo y del todo a las partes ayudará a los científicos a reconocer los caminos más adecuados.
