The Las Vegas 1 0 x 2 0 quadrangle, Nevada, Arizona, and California, contains rocks and structures from Precambrian through Holocene in age. It lies within the Basin and Range physiographic province adjacent to the westernmost portion of the Colorado Plateau. Miocene nonmarine sedimentary rocks of the Horse Spring Formation contain in excess of 100 tons U 3 O 8 in deposits at a grade of 0.01% or greater, and therefore meet National Uranium Resource Evaluation base criteria for uranium favorability. One favorable area lies in the South Virgin Mountains at the type locality of the Horse Spring Formation, although the favorable environment extends into the unevaluated Lake Mead National Recreation Area and Desert National Wildlife Range. Environments within the Las Vegas Quadrangle considered unfavorable for uranium include the Shinarump Conglomerate member of the Triassic Chinle Formation, Mesozoic sediments of the Glen Canyon Group, Precambrian pegmatites, Pliocene and Quaternary calcrete, Laramide thrust faults, and a late Precambrian unconformity

The scope of the Audit was comprehensive, addressing environmental activities in the technical areas of air, surface water/drinking water, groundwater, waste management, toxic and chemical materials, quality assurance, radiation, inactive waste sites, and environmental management. Also assessed was compliance with applicable Federal, state, and local regulations and requirements; internal operating requirements; DOE Orders; and best management practices. 8 tabs

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

A field investigation of flight anxiety: Evidence of gender differences in consumer behaviors among Las Vegas passengers

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

The Strip: Las Vegas and the Symbolic Destruction of Spectacle

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...

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

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

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'.

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

Preliminary study of favorability for uranium of the Sangre de Cristo Formation in the Las Vegas basin, northeastern New Mexico

International Nuclear Information System (INIS)

May, R.T.; Strand, J.R.; Reid, B.E.; Phillips, W.R.

1977-12-01

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

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.

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.

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

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

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.

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

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.

The VEGA Assembly Spectrum Code

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)

1985-12-01

The literature review and empirical analyses presented in this report were undertaken, for the most part, between August and October 1983. They are not comprehensive. 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. Finally, because actual transportation routes have not been designated, impacts on tourism generated specifically by transportation activities are not considered separately. Chapter 2 briefly discusses possible means by which a repository could impact tourism in the Las Vegas area. Chapter 3 presents a review of previous research on alternative methods for predicting the response of people to potential hazards. A review of several published studies where these methods have been applied to facilities and activities associated with radioactive materials is included in Chapter 3. Chapter 4 contains five case studies of tourism impacts associated with past events that were perceived by the public to represent safety hazards. These perceptions of safety hazards were evidenced by news media coverage. These case studies were conducted specifically for this report. Conclusions of this preliminary analysis regarding the potential impact on tourism in the Las Vegas area of a repository at Yucca Mountain are in Chapter 5. Recommendations for further research are contained in Chapter 6.

An Aerial Radiological Survey of the Las Vegas Strip and Adjacent Areas

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.

Geologic and geotechnical investigation of the Windsor Park subdivision North Las Vegas, Nevada

1994-01-01

The Windsor Park subdivision in North Las Vegas, Nevada has received widespread attention for damage to the homes and infrastructure from fissures, land subsidence and adverse soil conditions. Between March and July, 1992, Converse Consultants Southwest, Inc. conducted a geologic and geotechnical investigation for the Windsor Park Revitalization Project. The purpose of the work was to investigate the probable factors contributing to the reported damage and distress in the area, evaluate the potential for future damage, and assess the feasibility of possible mitigation and repair. The site is constructed on the juncture of at least two subsidence-related fault scarps, and earth fissures have been extensively mapped in the Windsor Park and surrounding area. A total of twenty-one trenches and fifteen borings were located within the subdivision and around the perimeter to observe subsurface geologic features and to collect samples for laboratory testing. The primary causes of damage within the development were found to be (1) earth fissuring and (2) expansive clays. The risk of future damage to structures at the Windsor Park site was also evaluated. A high potential for fissuring was found at the site, and future structural distress in the area will likely be similar to past damage. Although engineering upgrades will reduce the risk posed by underlying expansive clays, they cannot totally eliminate the risk from fissuring. 10 refs., 8 figs., 1 tab

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.

Vega-Lite: A Grammar of Interactive Graphics.

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.

SOURCE AND PATHWAY DETERMINATION FOR BERYLLIUM FOUND IN BECHTEL NEVADA NORTH LAS VEGAS FACILITIES

2004-07-01

In response to the report ''Investigation of Beryllium Exposure Cases Discovered at the North Las Vegas Facility of the National Nuclear Security Administration'', published by the U.S. Department of Energy (DOE), National Nuclear Security Administration (NNSA) in August 2003, Bechtel Nevada (BN) President and General Manager Dr. F. A. Tarantino appointed the Beryllium Investigation & Assessment Team (BIAT) to identify both the source and pathway for the beryllium found in the North Las Vegas (NLV) B-Complex. From September 8 to December 18, 2003, the BIAT investigated the pathway for beryllium and determined that a number of locations existed at the Nevada Test Site (NTS) which could have contained sufficient quantities of beryllium to result in contamination if transported. Operations performed in the B-1 Building as a result of characterization activities at the Engine Maintenance, Assembly, and Disassembly (EMAD); Reactor Maintenance, Assembly, and Disassembly (RMAD); Test Cells A and C; and the Central Support Facility in Area 25 had the greatest opportunity for transport of beryllium. Investigative monitoring and sampling was performed at these sites with subsequent transport of sample materials, equipment, and personnel from the NTS to the B-1 Building. The timeline established by the BIAT for potential transport of the beryllium contamination into the B-1 Building was from September 1997 through November 2002. Based on results of recently completed swipe sampling, no evidence of transport of beryllium from test areas has been confirmed. Results less than the DOE beryllium action level of 0.2 ???g/100 cm2 were noted for work support facilities located in Area 25. All of the identified sites in Area 25 worked within the B-1 tenant's residency timeline have been remediated. Legacy contaminants have either been disposed of or capped with clean borrow material. As such, no current opportunity exists for release or spread of beryllium

Aerial Radiological Surveys of the Las Vegas Strip and Adjacent Areas

International Nuclear Information System (INIS)

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

Science.gov (United States)

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.

Aerosol Light Absorption and Scattering Assessments and the Impact of City Size on Air Pollution

Science.gov (United States)

Paredes-Miranda, Guadalupe

The general problem of urban pollution and its relation to the city population is examined in this dissertation. A simple model suggests that pollutant concentrations should scale approximately with the square root of city population. This model and its experimental evaluation presented here serve as important guidelines for urban planning and attainment of air quality standards including the limits that air pollution places on city population. The model was evaluated using measurements of air pollution. Optical properties of aerosol pollutants such as light absorption and scattering plus chemical species mass concentrations were measured with a photoacoustic spectrometer, a reciprocal nephelometer, and an aerosol mass spectrometer in Mexico City in the context of the multinational project "Megacity Initiative: Local And Global Research Observations (MILAGRO)" in March 2006. Aerosol light absorption and scattering measurements were also obtained for Reno and Las Vegas, NV USA in December 2008-March 2009 and January-February 2003, respectively. In all three cities, the morning scattering peak occurs a few hours later than the absorption peak due to the formation of secondary photochemically produced aerosols. In particular, for Mexico City we determined the fraction of photochemically generated secondary aerosols to be about 75% of total aerosol mass concentration at its peak near midday. The simple 2-d box model suggests that commonly emitted primary air pollutant (e.g., black carbon) mass concentrations scale approximately as the square root of the urban population. This argument extends to the absorption coefficient, as it is approximately proportional to the black carbon mass concentration. Since urban secondary pollutants form through photochemical reactions involving primary precursors, in linear approximation their mass concentration also should scale with the square root of population. Therefore, the scattering coefficient, a proxy for particulate matter

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

Cities are concentrations of sociopolitical power and prime architects of land transformation, while also serving as consumption hubs of "hard" water and energy infrastructures. These infrastructures extend well outside metropolitan boundaries and impact distal river ecosystems. We used a comprehensive model to quantify the roles of anthropogenic stressors on hydrologic alteration and biodiversity in US streams and isolate the impacts stemming from hard infrastructure developments in cities. Across the contiguous United States, cities' hard infrastructures have significantly altered at least 7% of streams, which influence habitats for over 60% of North America's fish, mussel, and crayfish species. Additionally, city infrastructures have contributed to local extinctions in 260 species and currently influence 970 indigenous species, 27% of which are in jeopardy. We find that ecosystem impacts do not scale with city size but are instead proportionate to infrastructure decisions. For example, Atlanta's impacts by hard infrastructures extend across four major river basins, 12,500 stream km, and contribute to 100 local extinctions of aquatic species. In contrast, Las Vegas, a similar size city, impacts cities have local policy choices that can reduce future impacts to regional aquatic ecosystems as they grow. By coordinating policy and communication between hard infrastructure sectors, local city governments and utilities can directly improve environmental quality in a significant fraction of the nation's streams reaching far beyond their city boundaries.

Abundance of boron in Vega and Sirius

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.

Origen de la casiterita detrítica en los aluviones recientes de Tirados de la Vega-Golpejas (Salamanca

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.

Full Text Available In this paper, the interesting and significant chapter on the bloodletting, included in the medical treatise entitled the Liber de arte medendi (1564 of Cristóbal de Vega (1510-1573, has been studied. 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.

En este artículo se ha estudiado el interesante y significativo capítulo sobre la sangría, incluido en el tratado de medicina titulado Liber de arte medendi (1564 de Cristóbal de Vega (1510-1573. 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.

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

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.

Mourard, D.; Nardetto, N.; Ligi, R.; Perraut, K.

VEGA/CHARA is a visible spectro-interferometer installed on the CHARA Array at Mount Wilson Observatory. Combining high spectral resolution (6,000 or 30,000) and high angular resolution (0.3 mas), VEGA/CHARA opens a wide class of astrophysical topics in the stellar physics domain. Circumstellar environments and fundamental parameters with a high precision could be studied. We will present a review of recent results and discuss the programs currently engaged in the field of pulsating stars and more generally for the fundamental stellar parameters.

Basin amplification of seismic waves in the city of Pahrump, Nevada.

Energy Technology Data Exchange (ETDEWEB)

Abbott, Robert E.

2005-07-01

Sedimentary basins can increase the magnitude and extend the duration of seismic shaking. This potential for seismic amplification is investigated for Pahrump Valley, Nevada-California. The Pahrump Valley is located approximately 50 km northwest of Las Vegas and 75 km south of the Nevada Test Site. Gravity data suggest that the city of Pahrump sits atop a narrow, approximately 5 km deep sub-basin within the valley. The seismic amplification, or ''site effect'', was investigated using a combination of in situ velocity modeling and comparison of the waveforms and spectra of weak ground motion recorded in the city of Pahrump, Nevada, and those recorded in the nearby mountains. Resulting spectral ratios indicate seismic amplification factors of 3-6 over the deepest portion of Pahrump Valley. This amplification predominantly occurs at 2-2.5 Hz. Amplification over the deep sub-basin is lower than amplification at the sub-basin edge, location of the John Blume and Associates PAHA seismic station, which recorded many underground nuclear tests at the Nevada Test Site. A comprehensive analysis of basin amplification for the city of Pahrump should include 3-D basin modeling, due to the extreme basement topography of the Pahrump Valley.

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

La elección responde a dos cuestiones fundamentales; por un lado, ambos expresan un fuerte sentido de pertenencia regional al autodenominarse "naturales" de las áreas culturales sobre las cuales escriben; por la otra, ambos mantienen una relación compleja pero bien diferenciada con respecto a la problemática del mestizaje adscribiendo a identidades étnicas opuestas: mientras Garcilaso se presenta como inca, Ruy Díaz de Guzmán lo hace como español. 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

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.

Full Text Available Extreme temperatures and heat wave trends in five cities within the Sonoran Desert region (e.g., Tucson and Phoenix, Arizona, in the United States and Ciudad Obregon and San Luis Rio Colorado, Sonora; and Mexicali, Baja California, in Mexico and one city within the Mojave Desert region (e.g., Las Vegas, Nevada were assessed using field data collected from 1950 to 2014. Instead of being selected by watershed, the cities were selected because they are part of the same arid climatic region. The data were analyzed for maximum temperature increases and the trends were confirmed statistically using Spearman’s nonparametric test. Temperature trends were correlated with the mortality information related with extreme heat events in the region. The results showed a clear trend of increasing maximum temperatures during the months of June, July, and August for five of the six cities and statically confirmed using Spearman’s rho values. Las Vegas was the only city where the temperature increase was not confirmed using Spearman’s test, probably because it is geographically located outside of the Sonoran Desert or because of its proximity to the Hoover Dam. The relationship between mortality and temperature was analyzed for the cities of Mexicali, Mexico and Phoenix. Arizona.

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.

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

Full Text Available We quantified the spatio-temporal patterns of land cover/land use (LCLU change to document and evaluate the daytime surface urban heat island (SUHI for five hot subtropical desert cities (Beer Sheva, Israel; Hotan, China; Jodhpur, India; Kharga, Egypt; and Las Vegas, NV, USA. Sequential Landsat images were acquired and classified into the USGS 24-category Land Use Categories using object-based image analysis with an overall accuracy of 80% to 95.5%. We estimated the land surface temperature (LST of all available Landsat data from June to August for years 1990, 2000, and 2010 and computed the urban-rural difference in the average LST and Normalized Difference Vegetation Index (NDVI for each city. Leveraging non-parametric statistical analysis, we also investigated the impacts of city size and population on the urban-rural difference in the summer daytime LST and NDVI. Urban expansion is observed for all five cities, but the urbanization pattern varies widely from city to city. A negative SUHI effect or an oasis effect exists for all the cities across all three years, and the amplitude of the oasis effect tends to increase as the urban-rural NDVI difference increases. A strong oasis effect is observed for Hotan and Kharga with evidently larger NDVI difference than the other cities. Larger cities tend to have a weaker cooling effect while a negative association is identified between NDVI difference and population. Understanding the daytime oasis effect of desert cities is vital for sustainable urban planning and the design of adaptive management, providing valuable guidelines to foster smart desert cities in an era of climate variability, uncertainty, and change.

Full Text Available Porphyry Cu-Mo deposits have influenced surface water quality in high-Andes of north-central Chile since the Miocene. 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.

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.

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.

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.

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

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.

Characterization and Scaling of Black Carbon Aerosol Concentration with City Population Based on In-Situ Measurements and Analysis

Science.gov (United States)

Paredes-Miranda, G.; Arnott, W. P.; Moosmuller, H.

2010-12-01

The global trend toward urbanization and the resulting increase in city population has directed attention toward air pollution in megacities. A closely related question of importance for urban planning and attainment of air quality standards is how pollutant concentrations scale with city population. In this study, we use measurements of light absorption and light scattering coefficients as proxies for primary (i.e., black carbon; BC) and total (i.e., particulate matter; PM) pollutant concentration, to start addressing the following questions: What patterns and generalizations are emerging from our expanding data sets on urban air pollution? How does the per-capita air pollution vary with economic, geographic, and meteorological conditions of an urban area? Does air pollution provide an upper limit on city size? Diurnal analysis of black carbon concentration measurements in suburban Mexico City, Mexico, Las Vegas, NV, USA, and Reno, NV, USA for similar seasons suggests that commonly emitted primary air pollutant concentrations scale approximately as the square root of the urban population N, consistent with a simple 2-d box model. The measured absorption coefficient Babs is approximately proportional to the BC concentration (primary pollution) and thus scales with the square root of population (N). Since secondary pollutants form through photochemical reactions involving primary pollutants, they scale also with square root of N. Therefore the scattering coefficient Bsca, a proxy for PM concentration is also expected to scale with square root of N. Here we present light absorption and scattering measurements and data on meteorological conditions and compare the population scaling of these pollutant measurements with predictions from the simple 2-d box model. We find that these basin cities are connected by the square root of N dependence. Data from other cities will be discussed as time permits.

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.

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.

Artificial light at night, when observed at some distance from a city, results in a dome of sky glow, brightest at the horizon. The spectral power distribution of electric light utilized will determine its color of the light dome and the amount of light will determine its brightness. Recent outdoor lighting technologies have included blue-rich light emitting diode (LED) sources that may increase the relative amount of blue to green light in sky glow compared to typical high pressure sodium (HPS) sources with warmer spectra. Measuring and monitoring this effect is important to the preservation of night sky visual quality as seen from undeveloped areas outside the city, such as parks or other protected areas, since the dark-adapted human eye is more sensitive to blue and green. We present a method using a wide field CCD camera which images the entire sky in both Johnson V and B photometric bands. Standard stars within the images are used for calibration. The resulting all-sky brightness maps, and a derived B-V color index map, provide a means to assess and track the impact of specific outdoor lighting practices. We also present example data from several cities, including Las Vegas, Nevada, Flagstaff, Arizona, and Cheyenne, Wyoming.

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.

Full Text Available The global environmental challenge becomes tangible and urgent in cities. Thus, it is critical that we understand the capabilities of cities to transform what is today a negative environmental impact to a positive one. We must make cities part of the solution. One point of entry to this question is to view cities as a type of socio-ecological system that has an expanding range of articulations with nature's ecologies. Today, most of these articulations produce environmental damage. How can we begin to use these articulations to produce positive outcomes - outcomes that allow cities to contribute to environmental sustainability? The complex systemic and multi-scalar capacities of cities provide massive potential for a broad range of positive articulations with nature's ecologies.El desafío ambiental global se hace tangible y urgente en las ciudades. Por ende, es necesario que comprendamos cuáles son las potencialidades de las ciudades para transformar lo que hoy es un impacto ambiental negativo en uno positivo. En este sentido, la ciudad debe ser considerada como parte de la solución. Una ventana para mirar este asunto es la que considera a las ciudades como sistemas socio-ecológicos con un abanico de articulaciones con los sistemas ecológicos naturales. Hoy en día, la mayoría de estas articulaciones produce daños. ¿Cómo podemos empezar a utilizarlas para producir impactos positivos, que permitan una contribución de las ciudades a la sostenibilidad ambiental? Las potencialidades de carácter complejo y multi-escalar de las ciudades representan un potencial de gran relevancia para explorar un amplio rango de articulaciones positivas con las dinámicas ecológicas naturales.

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.

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

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

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.

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.

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 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.

"Piores que bestas feras": Garcilaso de la Vega e o imaginário hispano-inca sobre os Guarani Chiriguano

Directory of Open Access Journals (Sweden)

Protasio Paulo Langer

Full Text Available No presente artigo propomos uma análise do imaginário de Garcilaso de la Vega sobre os Chiriguano - povo guarani falante que, por volta do século XV, se estabeleceu nas fronteiras do império andino. O tenaz enfrentamento que travaram contra os exércitos imperiais incaicos e, posteriormente, contra os hispânicos ensejou que o cronista Garcilaso de la Vega descrevesse os Chiriguano como a antítese da civilização. Nossa análise incide sobre como esse cronista mestiço abordou os Chiriguano, no intuito de tecer similaridades entre o imaginário cristão e o inca.

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.

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

Energy Technology Data Exchange (ETDEWEB)

Puttagunta, S.

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.

Architects and urban planners have always been at the forefront of technical and social innovation processes, researching and proposing new urban models and buildings based on cognitive materials from both their own and other fields of knowledge. In fact, current society, including our ways of life and habits, could not be comprehended without the open, curious minds and progressive even defiant attitudes of architects such as Brunelleschi, Violletle- Duc, Perret, Le Corbusier and Fuller, who defied the threshold of conceptual and vital convention and staked everything on exploring and applying the characteristic technological breakthroughs of their day to architecture and the design of cities.

Hwang, Ho Young; Chang, Hyoung Woo; Jeong, Dong Seop

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.

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

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.

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.

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.

Association between degradation of pharmaceuticals and endocrine-disrupting compounds and microbial communities along a treated wastewater effluent gradient in Lake Mead

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

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.

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

La mayoría de estos episodios estuvieron relacionados con las reiteradas avenidas del barranco Guiniguada, cuyo cauce dividía a la urbe en dos partes, siendo la registrada en 1713 una de las principales por la dimensión del desastre y la demostración de la proverbial incapacidad de las autoridades para afrontar el problema, el cual no tuvo una solución parcial hasta los inicios del siglo XIX.Las Palmas was a city periodically shaken by a series  of natural catastrophes that generated great uncertainty, high economical expenses and deads in the bossom of a great part of popuiation.

The changing city model towards the Smart City that we will be seeing in the years to come will provide major opportunities to companies that know how to discover new products and services adapted to a new demand, or to companies that are able to position themselves in the sectors with the best growth prospects. We will also witness the disappearance of companies that are not able to adapt to these changes or that react too late. From an energy perspective, this change will necessarily require energy efficiency and the use of renewable energy sources. But what are the products and services that are going to be demanded most in future cities? What materials, technologies or processes will they require? What sectors will have the fastest growth as a result of the development of Smart. (Author)

Full Text Available A pesar del creciente interés que ha suscitado el estudio de los procesos de migración internacional desde una perspectiva de género, la mayoría de los estudios solamente describe la migración de hombres y mujeres por separado sin tener en cuenta sus interacciones, o reflexiona sobre la cuestión del empoderamiento de la mujer a través de la migración. Sin embargo, la transformación de familias, hogares y comunidades derivada de la migración es mucho más compleja y requiere de un enfoque relacional más detallado y profundo.En este artículo intento contribuir al estudio de este tema a través del análisis de un componente fundamental de la migración internacional, que es la organización de hogares transnacionales. Con objeto de poder aplicar una perspectiva de género en el análisis de la organización de hogares transnacionales, aplicaré el marco teórico gendered geographies of power desarrollado por Sarah Mahlery Patricia Pessar. El presente estudio está basado en un trabajo de campo sobre las diferentes estrategias que utilizan las mujeres (y hombres centroamericanos que emigran a Belice City para ‘salir adelante’. Sus historias muestran cómo las mujeres migrantes intentan utilizar su condición de mujer transnacional a su favor. A partir de sus experiencias y perspectivas, argumento que el discurso mundial de la migración internacional necesita de un replanteamiento que tomeen cuenta la interacción de hombres y mujeres y las geometrías de poder en que se encuentran los migrantes.

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.

Full Text Available El patrón de segregación residencial de las ciudades chilenas se está transformando en dos sentidos principales: está cambiando su escala geográfica y está aumentando su malignidad. Estos cambios parecen estar afectando a la mayoría de las ciudades latinoamericanas. Están vinculados con las políticas de liberalización de los mercados de suelo y con los procesos de globalización económica y cultural de las últimas décadas. En el artículo se entrega información empírica sobre los efectos de estos cambios en tres ciudades chilenas (Santiago, Valparaíso, Concepción; y se discute teóricamente la relación entre desigualdad social y segregación espacial, rechazando el enfoque usual que ve a la segunda como un mero reflejo en el espacio de la primeraThe pattern of residential segregation is undergoing two crucial changes in Chilean cities: its geographical scale is shifting, and segregation’s malignancy is increasing. Seemingly, these changes are affecting most of Latin American cities.

This paper presents empirical data showing the effects of these changes for three Chilean cities (Santiago, Valparaíso, Concepción; and theoretically discusses the relationship between social inequality and spatial segregation, rejecting the usual approach that considers the latter as a mere spatial reflection of the first

SUMMARY Somehow, the occultations of reality allow us to think about the values of the city capable of becoming their identities and their habitability engines. The city should not be considered with keys that lead to irrational consumption to the extent that deteriorate and become something that they were not. Habitability must be measured by the identity of the inhabitants with their city and we must recognize the value of the invisible “walkers” who are able to identify the urban capacity of our societies against the“private management” that the public administration normally does, for example with the tourism. All of us together make up the city, inhabiting it but not devouring to destroying it. Be aware of these issues opens a door of hope towards the future because it marks new directions.

Full Text Available RESUMEN Eisenman superpone y entreteje tiempos distintos en sus ciudades de arqueología artificial donde a través de distintas estrategias de escalado y superposición (scaling y overlapping se rescatan momentos pasados que se yuxtaponen con instantes futuros. Ensamblaje, montaje, collage de distintas capas dan como resultado un trastrocamiento o una nueva re-significación. En algunas de estas ciudades las arqueologías eran ficticias, pero en otras eran reales, aunque superpuestas en un proceso de una absoluta artificialidad. Todas ellas son ejemplos donde la arquitectura revela su antigua condición de permanencia a la vez que asume la alteración como posibilidad de repensar lo existente. Eisenman es el ardid que lo hace posible, pasando del uso del signo al texto, de la sintaxis a la semántica y de la gramática a la memoria. En los proyectos que se estudian en este artículo se pasa de trabajar con objetos a trabajar con las huellas que los procesos dejan a modo de palimpsestos o mapas-operativos. SUMMARY Eisenman superimposes and interweaves different times in his cities of artificial archaeology where, through different strategies of scaling and superimposition, past times are rescued and juxtaposed with future moments. The assembly, montage, and collage of different layers result in a transformation or a re-signification. In some of these cities the archaeologies were fictitious, but in others they were real but superimposed in a process of absolute artificiality. These are all examples where architecture reveals its former condition of permanence while accepting change as a chance to rethink what exists. Eisenman is the clever device that makes it possible, passing from the use of the sign to the use of text, from syntax to semantics and from grammar to memory. The projects discussed in this article pass from working with objects to working with the traces that the processes leave, such as palimpsests or operational-maps.

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.

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

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.

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».

Cuatro estrategias globales de localízación de estos bancos y dos domésticas fueron identificadas. Las seis estrategias resultan de la aplicación de uno de los métodos de análisis multivariado, el análisis de componentes principales, en una matriz compuesta por 54 ciudades y 31 bancos. Consideradas las funciones de la ciudad mundial, se adoptó el concepto de gateway city, de Alan Pred, para interpretar las respectivas estrategias. La hinterland de la ciudad mundial fue entendida como sus enlaces funcionales con otras ciudades del país, creados en la economía global por los productores de servicios con alto valor agregado, ubicados en la ciudad mundial. Los resultados revelan que San Pablo articula las economías nacional y global como gateway city y que Curitiba emerge como una alternativa a San Pablo en esta función. Además, muestran que la producción en ventas de importantes ciudades de la red urbana brasileña poco contribuye para el desempeño de estas urbes en el contexto globafizado de los bancosThis exploratory study shows how the major hanks operating in Brazil in 2003 apply the two global practices - concentration and dispersion - in the Brazilian urban environment. Four global and two domestic location strategies of those banks were identified. The strategies were found employing the multivariate method of principal component analysis in a matrix of 54 cities versus 31 banks. In the light of world city functions, the gateway city concept as defined by Alan Pred was the basis for interpreting the six bank location strategies. The hinterland of a world city was understood as its functional links to other cities in the country, created in the global economy by advanced producer services in the world city. According to the

Full Text Available OBJECTIVE: To understand the critical factors that are likely to influence road traffic fatality rates in large cities around the world in the next few decades. MATERIAL AND METHODS: Road traffic fatality data for 56 cities around the world and for cities with a population of greater than 100 000 in the USA were collected and analysed to understand factors affecting differences in fatality rates. RESULTS: There are wide variations in fatality rates across income levels and within similar incomes levels. The risk varies by a factor of about 20 between the best and the worst cities. CONCLUSIONS: These patterns appear to indicate that it is not enough to have the safest vehicle and road technology to ensure low road traffic fatality rates. City structure, modal share split, and exposure of motorists and pedestrians may have a significant role in determining fatality rates, in addition to enforcement, vehicle crashworthiness and road design.OBJETIVO: Entender los factores críticos con probabilidad de influir en las tasas de fatalidad por tránsito en las grandes ciudades del mundo durante las próximas décadas.

The 2014 national seismic-hazard model for the conterminous United States incorporates new scientific results and important model adjustments. The current model includes updates to the historical catalog, which is spatially smoothed using both fixed-length and adaptive-length smoothing kernels. Fault-source characterization improved by adding faults, revising rates of activity, and incorporating new results from combined inversions of geologic and geodetic data. The update also includes a new suite of published ground motion models. Changes in probabilistic ground motion are generally less than 10% in most of the Intermountain West compared to the prior assessment, and ground-motion hazard in four Intermountain West cities illustrates the range and magnitude of change in the region. Seismic hazard at reference sites in Boise and Reno increased as much as 10%, whereas hazard in Salt Lake City decreased 5–6%. The largest change was in Las Vegas, where hazard increased 32–35%.

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.

Derivation of intermediate to silicic magma from the basalt analyzed at the Vega 2 landing site, Venus.

Science.gov (United States)

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.

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.

Applying the concept of effective temperature (ET), a scenario of human bioclimatic conditions for Mexico City is presented by using results from both GCM regional predictions for CO{sub 2} doubling and temperature trend projections from an urban station. Current and future bioclimatic maps for Mexico City and their conurbation are presented. Current environmental conditions will likely change toward a warmer atmosphere due to both the urbanization process and global greenhouse effect. The impact on the population will be more important during the warm season (March- May) when the bioclimate of the city will likely shift away from current neutrality to the next comfort scale category (ET 24-27 Celsius degrees) of warm conditions covering most of the capital city.

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

The primary objective of this part of the project is to develop and implement a method that compensates for the inefficiency of the green LED. The proposed engineering solution which will be the backbone of this project will be to use RGBW combination in every pixel to save energy. Two different RGBW geometrical pixel configurations will be implemented and compared against traditional LED configurations. These configurations will be analyzed for energy efficiency while keeping the quality of the display the same. Cost of the addition of white LEDs to displays along with energy cost savings will be presented and analyzed.

Full Text Available Floods are a natural phenomenona that normally occur during Summer of every year and sometimes extraordinarily at any time in Huancané, damaging enormous areas near the lake due to lake transgressions and the overflowing of de Ramis and Huancané rivers. This origins uncountable losses to peasants’ patrimony, such as cultigens, cattle, housing, etcétera. As it is expected, this brings the assistance of both public and private institutions, to assure the surviving of the people damnified.The most serious floods took place in 1986 and 2003 that interrupted all means of comunication to the city of Huancané. As usual, the government attention to these terrible problems, consisted in short time actions to cap the moment, without any understanding of the real causes of these phenomenona, which are the filled beds of the fluvial beds and the shallowness of Lake Titicaca in the outflet of the Ramis river that collects the water from the chain of mountains at the N and NW of the Peruvian Altiplano.Las inundaciones como fenómenos naturales se presentan anualmente en cada verano y extraordinariamente cada cierto tiempo en Huancané, afectando enormes áreas de planicies contiguas al lago. Son el resultado de la transgresión lacustre y desbordamientos de los ríos Ramis y Huancané; y causan cuantiosas pérdidas patrimoniales de los campesinos: cultivos, ganado, viviendas, etcétera. Como es de esperarse, esto pone en acción el apoyo de instituciones privadas y públicas para asegurar la sobrevivencia de la población damnificada.Las dos inundaciones más graves fueron en 1984-1986 y 2003 que interrumpieron las carreteras de conexión a la ciudad de Huancané. Los esfuerzos del gobierno incidieron en respuestas momentáneas, sin comprender que la verdadera causa de estos fenómenos se encuentra en la colmatación de los lechos fluviales y del fondo del lago Titicaca, en la desembocadura del río Ramis que recibe las aguas pluviales desde las

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

Full Text Available El artículo se propone dar cuenta de que el paso de una ciudad compacta a una ciudad dispersa es hoy en día uno de los procesos que está presente con mayor intensidad en ciudades de carácter metropolitano. En Chile, la capital nacional no es una excepción a ello, ya que pese a la disminución de la velocidad de crecimiento demográfico alcanzado en los últimos años, Santiago ha mostrado una fuerte tendencia de desarrollo hacia las áreas periféricas. Los factores que lo explican son diversos y complejos; ello no obstante, se reconoce que son las migraciones, en particular las que ocurren al interior de la ciudad, las que han jugado un rol decisivo en el proceso de dispersión urbana. A los impactos derivados en el crecimiento físico se suma la complejización de la geografía social de sus espacios, producto de los atributos asociados de la población migranteThis paper deals with the transformation of compact cities into disperse cities, which is now days one of the process intensively occurring in metropolitan areas. In Chile, the country capital city (with 5.5 million people, is not an exception, nevertheless the demographic growth rates diminish, as is observed in latest years. Santiago has shown a strong oriented growth towards the periphery. The explanatory facts are complex and diverse. Nevertheless the migratory movements, particularly those occurring within the urban sector, are recognize to have a principal and decisive role in this urban process. Besides the physical way of expansion, social geographical aspects of the city are considered too, since these are qualities of the migrant population

Full Text Available Landscape painting was developed in the romantic and realistic modernism with the representation of rural or regional landscapes. French impressionism was the first stream interested in city representation emphasizing the habits and the social way of life in the public space defined as cultural centers. Years later, cubism represented cities interpreting the form as a geometric geomorphology of cubes. The main target of this contribution is the analysis of cities characterization in both pictured streams at the end of XIX century and beginning of XX.

La pintura pisajistica que priorizó la modernidad desarrollo diversas corrientes entre las cuales el romantícismo y el realismo empiezan a dar cuenta de temas más cercanos con la realidad que se vivía en ese momento. El impresionismo es la primera corriente que puede considerarse netamente urbana en donde las costumbres y la ciudad son el eje central de su representación. Con el tiempo el cubismo utiliza una forma más simbólica y la deconstruye.

Tributos negociados: Las “questie”/subsidios de las villas catalanas en la primera mitad del siglo XIV

Full Text Available This article examines the questie/ subsidies requested by the Catalan- Aragonese monarchs from the towns of the royal domain of Catalonia between 1309 and 1359. From the point of view of the Crown, the importance of these tributes lies in the fact that they were the monarchy’s main way of financing prior to the transcendental changes in taxation of the decades of 1350 and 1360. And, from the point of view of the towns, the necessity to negotiate with the king and his officials, year after year, the amount of the questie/subsidies due in every small city, contributed to the increasing financial autonomy of the municipalities and, beyond that, to the social and institutional coordination of that community.

En este artículo se estudian las questie/subsidios pedidas por los monarcas catalanoaragoneses a las villas de realengo de Cataluña entre 1309 y 1359. Desde el punto de vista de la Corona, la importancia de estos tributos radica en que fueron la principal forma de financiación de la monarquía antes de las trascendentales transformaciones fiscales de las décadas de 1350 y 1360. Y, desde la perspectiva de las villas, la necesidad de negociar con el rey y sus oficiales, año por año, el volumen de las questie/subsidios a pagar por cada pequeña ciudad contribuyó a la creciente autonomía financiera de los municipios y, más allá, a la vertebración social e institucional de la propia comunidad.

Full Text Available Based on actual land use in Yancheng city, this paper establishes the ecological security of the land index system from the perspectives of economy, society and ecological environment. Using the catastrophe theory and pressure-state-response (PSR model, the purpose of the research was to judge the degree of land ecological security in Yancheng city from 2002 to 2011 and determine the requirements to ensure the sustainable development of this region. The results showed that over the ten years, the pressure, state, response and synthetic values of the land ecological security were evaluated as safe in 2003 and 2007 and at middle level in 2002 and for 2004 to 2006 and then dropped to insecure for 2008 to 2009 and very insecure for 2011 to 2012. The ecological security level and circumstance of land use in Yancheng city has generally declined. During this period, the land use pattern of Yancheng city was under tremendous pressure from the conflict between rapid urbanization and economic development, as well as conservation and rehabilitation of the eco-environment. This research shows that conditions for the land ecosystems of Yancheng city are not optimistic and, as such, should draw the attention of responsible government departments. Future policy options should aim to mitigate these problems through the control of population growth and the improvement in quality of life, protection of wetland and forest land, application of scientific concepts of development, coordination of economic development and land utility, and strengthening the control functions of land-use planning.   Resumen De acuerdo con el uso actual del suelo en la ciudad de Yancheng, en el este de China, este artículo establece la seguridad ecológica del sistema de tierras desde las perspectivas económica, social y ecológica.

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

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 greater abuse of methylphenidate among ADHD subjects might indicate their using it as self-medication, raising a possible indication for its prescription for that subgroup of MMT patients. The high rate of methylphenidate abuse in Israel needs future study. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available The domestic architecture of the western cities of Conventus Hispalensis remains an open line of research still being developed. So, even though there is a previous archaeological literature, there had not been a study establishing a comprehensive overview that integrates de analysis of its architecture, ornamental program, material culture and its incorporation into the urban network. All these explanatory factors are currently of great interest due to the importance of the domestic architecture in Hispania in the past decades (Corrales, 2012, 256. Therefore, the generation of a theoretical framework (Wallace-Hadrill, 1997, 219 was necessary in order to globally understand the urban domestic architecture in the ancient cities of the territory of Huelva. Thanks to new archaeological evidence, this could lead to a renewed interpretative approach. | La arquitectura doméstica de las ciudades occidentales del Conventus Hispalensis continúa siendo una línea de investigación abierta y aún por desarrollar. Así, a pesar de que existe una literatura arqueológica previa, hasta la fecha, no se había realizado un estudio que presentara una panorámica global que integrara el análisis de su arquitectura, programa ornamental, cultura material y su inserción en la trama urbana, factores explicativos de gran interés en la actualidad, a tenor del desarrollo que la arquitectura doméstica en Hispania ha sido objeto en las últimas décadas (Corrales, 2012, 256. Así, pues, se hacía necesaria la generación de un marco de trabajo teórico (Wallace– Hadrill, 1997, 219 mediante el cual, la edilicia doméstica de las ciudades del territorio onubense se entendiese como una reflexión global, en la que, de la mano de las nuevas evidencias arqueológicas, se pudiera producir una aproximación interpretativa renovada.

Full Text Available The Castilian monarchy promulgated, between 1494 and 1511, one series of ordinances with which to regulate and to improve the textile production. These laws were seeking to increase the technical quality of the cloths. For it, one entrusted the control of the production for the guilds organizations of the principal cities. Which faced for the above mentioned control the big producers, who were claiming forms of organization of capitalist character, which they could not implant due to the limitations imposed by the royal laws. That of this form did that the trade-union system of textile production was kept in force during the whole Modern Age.

La monarquía castellana promulgó, entre 1494 y 1511, una serie de ordenanzas con las que regular y mejorar la producción textil. Estas leyes buscaban aumentar la calidad técnica de los paños. Para ello, se encargó el control de la producción a las organizaciones gremiales de las principales ciudades. Las cuales se enfrentaron por dicho control con los grandes productores, que pretendían formas de organización de carácter capitalista, que no pudieron implantar debido a las limitaciones impuestas por las leyes reales. Que de esta forma hicieron que el sistema gremial de producción textil se mantuviese vigente durante toda la Edad Moderna.

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.

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

2017-11-01

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».

We studied the possible effects of atmospheric electric fields, generated in thunderstorms, on the cosmic ray intensity detected at the Earth's surface by investigating the variations of the counting rates of the cosmic-ray nucleonic component, obtained from the neutron monitor installed in Mexico City, for thunderstorms during 1996 and 1997. These were years of minimum solar activity. We compare our experimental results with the general theory of cosmic ray meteorological effects by Dorman (1995). The observed intensity variation is about 0.2%. According to Dorman (1995), the effect should be between 0.27% and 0.81% on the counting rate of the neutron monitor when the atmospheric electric field intensities are around 100 to 300 Vcm-1.Our results show that either the electric field in Mexico City had less intensity than assumed by Dorman (1995), or the electric field is not uniform in time and height during the development of the thunderstorm.

The island factor in the cities of Las Palmas de Gran Canaria and Santa Cruz de Tenerife, their meteorology and the proximity to the African Continent that originates the natural particulate matter transport over the islands, cause some specific features in their air quality. The aim of this paper is to characterize the air pollution from 2000 to 2004 as exposure indicator of both cities inhabitants. 24 hour daily average variables of PM10, PM2,5, NO2, SO2 and O3 , 8 hours daily maxima moving averages of O3 y CO and 1 hour maxima of SO2, NO2, O3, CO, PM10 y PM2,5 were calculated. Daily levels of coarse particles were obtained subtracting PM2,5 from PM10. African dust events were identified. In Sta. Cruz de Tf daily means of SO2 (14.0 microg/m(3)N) and ozone levels (44.4 microg/m(3)N ) were higher than Las Palmas de GC levels (8.0 y 28.3 microg/m(3)N). Daily means of NO2 in Las Palmas de GC: 45.8 microg/m(3)N where higher than Sta. Cruz de Tf levels: 30.3 microg/m(3)N. Due to African dust outbreaks, some days in both cities exceeded 600 microg/m(3) of PM10 and 200 of PM2.5 24-h average. The air quality patterns were characterized by very high levels of African dust outbreaks that affect all PM size fractions. Different O3 seasonality exists respect European cities in addition to an urban-industrial ambient air in Sta. Cruz de TF and clearly urban in Las Palmas de GC. These results have to be considered in order to lay the foundations to suitable surveillance systems, analyse the potential impact on the Canary Islands citizens health and to get conclusions.

Full Text Available Objective: To monitor the presence of pharmaceutical residues of 14 psychoactive drugs belonging to three therapeutic groups in the watersheds of Galicia (Spain. Method: Five sewage treatment plants were selected in the main cities of Galicia. Thirteen psychoactive pharmaceutical compounds and one metabolite were chosen. In addition, tap water samples were taken from public places and private residences in the selected cities. Results: In all the water samples analyzed, the highest concentrations corresponded to the group of anxiolytics. In particular, high concentrations of lorazepam were found in river and tap water samples. Conclusions: This investigation demonstrates the presence of psychoactive pharmaceuticals in the watersheds of the autonomous region of Galicia and the conversion of metabolites to parent compounds. This work also shows the need to increase environmental monitoring of watersheds and to improve sewage and drinking water treatment processes to remove these pharmaceuticals.Objetivo: Monitorizar la presencia de 14 fármacos psicoactivos pertenecientes a tres grupos terapéuticos en la cuenca de Galicia. Método: Se seleccionaron cinco estaciones depuradoras de aguas residuales en las principales ciudades de Galicia. Se escogieron trece compuestos farmacéuticos psicoactivos y un metabolito. Asimismo, se tomaron muestras de aguas del grifo de espacios públicos y privados en las ciudades seleccionadas. Resultados: En todas las muestras de agua analizadas, las mayores concentraciones han correspondido al grupo de los ansiolíticos, y especialmente el lorazepam ha aparecido en altas concentraciones en las muestras de aguas de río y del grifo. Conclusiones: Esta investigación demuestra la presencia de fármacos psicoactivos en las cuencas de Galicia y la reversión de los metabolitos a sus compuestos parentales.

Full Text Available RESUMEN Entre mediados del siglo XIX y principios del XX la ciudad de Londres sufrió una radical transformación social y espacial convirtiéndose en una ciudad moderna. Entre estos procesos de transformación se encuentra la división de la ciudad en términos de género consecuente con la implementación progresiva de los códigos morales evangélicos imperantes en la sociedad de la época. No obstante, entre 1859 y 1914, un grupo de mujeres rompieron estas divisiones a través de distintos mecanismos de acción utilizados para reclamar tanto sus derechos como ciudadanas como un lugar en la esfera pública urbana. Entre estos mecanismos se encuentra la progresiva apertura de espacios de asociación como estrategia de infiltración en una ciudad exclusivamente masculina. El surgimiento de clubs y asociaciones femeninos consolidó una sólida red relacional que posteriormente eclosiona con las grandes marchas sufragistas en el espacio público a principios del siglo XX. A través de esta primera red de lugares se evidencia una ciudad paralela de las mujeres definida por unos mapas alternativos de la ciudad, que serían, no obstante, largamente marginados por la historiografía moderna. SUMMARY Between mid-nineteenth and early twentieth century, London underwent a radical social and spatial transformation to become a modern city. A key part of this transformation process is a gendered division of the city related to a progressive implementation of evangelical moral codes prevailing in the society of that time. However, between 1859 and 1914, a group of women broke these divisions through different mechanisms of action to reclaim both a place in the urban public sphere and their citizen rights. Among these mechanisms, there is a strategy of infiltration in this male town that is implemented through a progressive opening of spaces of association. The progressive opening of women’s clubs and associations consolidated a solid relational network

Full Text Available La influjo de organismos internacionales en la aplicación de políticas orientadas a la solución del “problema de la vivienda” de los sectores pobres en los países latinoamericanos ocurre desde hace varios decenios. El origen suele ubicarse a partir de la década de 1950, cuando en los países de la región se observa la intensificación del crecimiento vegetativo y de las emigraciones rurales-urbanas. El comienzo del milenio encuentra nuevamente a las ciudades de América Latina como escenarios de profundas transformaciones y de problemas complejos, entre los cuales la resolución de las carencias habitacionales se reposiciona en la agenda internacional como un “eje estratégico” para la superación de la pobreza y la precariedad urbana. En este marco destaca el surgimiento de Cities Alliance, una asociación que agrupa a instituciones y organismos de desarrollo con el propósito de asistir a las ciudades a abordar los desafíos urbanos del siglo XXI, entre ellos la eliminación-mejoramiento de los barrios marginales. En la primera parte de la ponencia se presentan los principales rasgos de Cities Alliance destacando: enfoque dominante, orientaciones de las estrategias o modelos de intervención de gobiernos y otros actores, políticas y programas impulsados. En la segunda parte se realizan algunos señalamientos sobre la actual política habitacional en la ciudad de Neuquén a la luz del planteo de Cities Alliance.

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.

Full Text Available ResumenEl cuidado es una experiencia humana holística, que permite conservar la vida y las condiciones de salubridad y adaptarse a situaciones cambiantes. La enfermería tiene como eje central la ciencia del cuidado. Por eso es de gran importancia conocer cuáles son las prácticas de cuidado que tienen las gestantes, y si hay diferencias en este cuidado entre las gestantes adolescentes y las adultas. Para responder este interrogante, se realizó un estudio comparativo en la ciudad de Santa Marta donde, a través de un muestreo intencional por conveniencia, se estudiaron 47 gestantes adolescentes y 92 gestantes adultas. Se valoraron las prácticas de cuidado en cuanto a alimentación, estimulación prenatal, ejercicio y descanso, higiene y cuidados personales, sistemas de apoyo y consumo de sustancias no beneficiosas. Se concluyó que en ambos grupos las prácticas son regulares. La adulta estimula mas a su hijo por nacer, tiene mejores prácticas de higiene y sistemas de apoyo y consumen menos sustancia no beneficiosas. La adolescente tiene mejor práctica de ejercicio y descanso y la alimentación es regular en ambos grupos.

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.

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

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.

Full Text Available Este trabajo examina las contribuciones de los escritores contemporáneos de Guinea Ecuatorial a la construcción de nociones de ciudades y sus habitantes en la narrativa africana contemporánea. Aunque el documento se basa principalmente en obras de María Nsue Angüe, Maximiliano Nkogo Esono, Juan Tomás Ávila Laurel, Donato Ndongo-Bidyogo y César Mba Abogo, la interpretación de estos escritores de las ciudades se examina en relación con un contexto más amplio de la escritura africana representada por los siguientes autores anglófonos, Ama Ata Aidoo, Sefi Atta, Kojo Laing y Sinyangwe Binwell así como la francófona Calixthe Beyala. El tratamiento particular de ciudades por parte de los escritores guineoecuatorianos, en comparación con las tendencias en otros ejemplos de la literatura y crítica africanas, tiene su origen en las preocupaciones socio-políticas en el contexto de la petroeconomía de su país. This paper examines the contributions of contemporary Equatoguinean writers to the construction of ideas of cities and their inhabitants in contemporary African narrative. Although the paper draws mainly on works by María Nsue Angüe, Maximiliano Nkogo Esono, Juan Tomás Ávila Laurel, Donato Ndongo-Bidyogo and César Mba Abogo, these writers’ rendition of cities is examined with reference to a wider context of African writing represented by Anglophone and Francophone writers Ama Ata Aidoo, Sefi Atta, Kojo Laing, Binwell Sinyangwe and Calixthe Beyala. The particular treatment of Equatoguinean cities in comparison to trends in other examples of African literature and criticism, are traced to the socio-political concerns in the context of Equatorial Guinean new petro-economy.

Revolución y contrarrevolución en la ciudad global: las expectativas frustradas por la globalización de nuestras ciudades

Full Text Available El análisis pesimista, incluso catastrófico, prevalece en los estudios sobre la urbanización global. Por ejemplo, los Informes de PNUD-Habkat o del Worldwatch Institut. O los artículos e intervenciones en encuentros intelectuales. Lo cual no obsta que se reconozca el potencial transformador e integrador de las ciudades. El discurso positivo sobre las libertades ciudadanas que la revolución urbana en curso hace posible forma parte de nuestra cultura. Son dos caras de la realidad. Muchas ciudades, europeas y americanas, han promovido la renovación de sus áreas centrales, que, en muchos casos, abarca casi todo el municipio con una revalorización de la ciudad compacta y heterogénea, caracterizada por la calidad del espacio público. Pero los desarrollos urbanos, las regiones metropolitanas, multiplican las desigualdades en el territorio, generan espacios confusos, físicamente fragmentados y socialmente segregadores. La revolución urbana actual es frustrante. El desafío político, urbanístico y cultural es hoy "hacer ciudad" en el conjunto de las regiones caracterizadas por la urbanizaciónA pessimistic analysis, even catastrophic, prevails in studies of global urbanization. For example, the Reports of the UNDP-Habitat or the Worldwatch Institute, or the articles and presentations in intellectual fora. This does not mean that the transformative and integrative potential of cities is not recognized. The positive discourse about citizens' liberties that the urban revolution, currently in process, makes possible forms part of our culture. These are the two sides of this reality. Many cities, European and American, have promoted regeneration of their central areas that, in many cases, deal with almost an entire municipality, with a revaluing of the compact, heterogenous city characterized by the quality of public space. However the urban developments, the metropolitan regions, multiply inequalities over the landscape, generating spaces that

The aim of the study was to present the occurrence of invasive alien plant species in two forest reserves: "Las Lagiewnicki"and "Polesie Konstantynowskie", located within the city of Lodz (Central Poland). Currently, five vascular plants (Impatiens parviflora, Juncus tenuis, Padus serotina, Quercus rubra, Robinia pseudoacacia) and one moss (Orthodontium lineare) considered as invasive were found in the studied reserves. Invasive plant species accounted for a small percentage of the flora in the studied reserves, and their sites were mainly concentrated in areas transformed by human activity. The most common species were Impatiens parviflora and Padus serotina. Due to the location of the reserves within city borders and the proven negative effect of the found species on ecological systems, their sites should be monitored. (author)

The new EU objectives included in its Circular Economy Package and the Spanish 2016-2022 Waste Plan define a new scenario of transformation of municipal solid waste management. They also define the hierarchization of waste treatment: reduction, reuse, recycling, energy valorization and, as a last resort, landfill. The use of new technologies is contributing to this transformation, including both separation at source and collection and treatment. Improved traceability of wastes via the use of sensors, technological innovation in management and the emergence of a fifth bin for selective collection of organic wastes are only some of the new elements that are increasingly common in Spanish cities.

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

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.

Full Text Available Las lesiones de tráfico no-intencionales a escala global causan 1.2 millones de muertes cada año, afectan a personas en edad productiva y son eventos potencialmente prevenibles. En México es una de las causas principales de mortalidad nacional y el Distrito Federal registra más de 8% en este rubro. Los sistemas prehospitalarios han sido diseñados para extender los servicios médicos hospitalarios a la población, a través de la interacción de una compleja red de transportación, comunicación, recursos materiales y humanos, recursos económicos y participación pública. Estos sistemas pueden ser diseñados de distintas maneras, dependiendo de la disponibilidad, capacidad y calidad de recursos, y con base en las necesidades de la comunidad, de acuerdo con leyes y reglamentos establecidos. En México varias instituciones y organizaciones ofrecen servicios prehospitalarios sin que exista coordinación, regulación y evaluación de su desempeño, a pesar de las elevadas tasas de morbilidad y mortalidad ocasionadas por lesiones y enfermedades prevenibles o para las cuales existen tratamientos efectivos aplicados durante la fase prehospitalaria. La medicina prehospitalaria puede colaborar hacia la reducción de morbilidad y mortalidad por lesiones que requieren pronta atención médica, por lo que es de gran importancia evaluar el desempeño del sistema y determinar las oportunidades para su futuro desarrollo.Unintentional vehicle traffic injuries cause 1.2 million preventable deaths per year worldwide, mostly affecting the population in their productive years of life. In Mexico, unintentional vehicle traffic injuries are one of the main causes of death; in Mexico City they account for 8% of deaths.

Los sectores de altos ingresos se aíslan voluntariamente en zonas periféricas exclusivas, en barrios autosuficientes, dotados de costosas viviendas, servicios, seguridad privada, etc. Los más carenciados se ubican también en la periferia pero en áreas de menor valor, conocidas con el nombre de "villas de emergencia" o "villas miseria", caracterizadas por un alto grado de precariedad y deficiente equipamiento social. El trabajo intenta reflexionar sobre las relaciones que se establecen entre estos espacios urbanos y las identidades de sus habitantes.___________________ABSTRACTIn the last decade, the majority of Argentinean cities developed according to two patrons: territorial extension and internal segmentation.

Consumo ilimitado, eficiencia y desigualdad urbana. Definición socioecológica del consumo urbano desde las perspectivas del marxismo y el metabolismo

Directory of Open Access Journals (Sweden)

Rubén Miguel Águeda

2015-12-01

Full Text Available Resumen Las mejoras en la eficiencia de los sistemas urbanos pueden resultar insuficientes en la búsqueda de una ciudad más respetuosa con el medio natural si el consumo en el interior de las ciudades sigue creciendo sin control y, especialmente, si este incremento no es consecuencia directa del comportamiento de los consumidores. Para explicar cómo la estructura de la ciudad interviene en el consumo se recurre a dos formas diferentes de entender el espacio urbano. Por un lado el estudio del metabolismo urbano cuantifica los componentes que intervienen en el consumo, por otro, las interpretaciones marxistas de la ciudad tratan de explicar las estructuras sociales, políticas y económicas que lo condicionan. El resultado es una teoría conjunta que permite interpretar todos los fenómenos y actividades que engloba el término consumo, aglutinando tanto la dimensión ecológica de éste como los aspectos sociales y políticos que intervienen en el mismo. Palabras clave Estructura urbana, sostenibilidad, flujos de circulación, escasez, desequilibrios sociales y ambientales Abstract Improving the efficiency of urban systems may prove insufficient in the pursuit of a friendlier city with the environment if consumption within cities continues growing out of control and, in particular, if this increase is not a direct consequence of consumers’ behavior. For explaining how the structure of the city intervenes in consumption we can use two different ways of understanding urban space. On one hand urban metabolism quantifies the components involved in consumption, on the other Marxist interpretations of the city try to explain the social, political and economic structures that condition it. The result is a joint theory that allow us to interpret every phenomenon and activity within the term consumption and that bring together both ecological, political and social dimensions involved.

Full Text Available Active and abandoned mines may present health risks, especially to children, from environmental exposure to airborne chemical elements, such as Pb, As, and Mn. X-ray fluorescence analysis of tailings at the Three Kids Mine show they contain high levels of: Pb (15,300 mg/kg, As (3690 mg/kg, and Mn (153,000 mg/kg. Soil was sampled along eight transects, radiating from the dried tailings ponds. Concentrations of Mn and Pb to the NE are at background concentrations at 4.8 km, and, As and Sr at 3.2 km from the mine. Going SW to the City of Henderson, all elements are at background at 1.6 cm, with the closest houses at 1.8 km. The United States Environmental Protection Agency (USEPA Regional Screening Levels (RSLs are exceeded for Pb, As and Mn at 0.8 km on all transects except one. The RSLs are exceeded for Pb, As and Mn on the NE transects at 1.6 km. Future home sites are on a NE transect between 0.4 km and 2.3 km downwind from the tailings ponds, in an area highly impacted by tailings which exceed the USEPA RSLs. This research demonstrates that there has been the farthest transport of tailings offsite by the prevailing winds to the NE; the closest currently-built homes have not received measurable tailings dust because they are upwind; and that precautions must be taken during the proposed remediation of the mine to restrict dust-transport of Pb, As, and Mn to avoid human exposure and ecological damage.

2009-06-01

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.

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.

La ciudad com-fusa: mercado y producción de la estructura urbana en las grandes metrópolis latinoamericanas

Full Text Available Con la crisis del fordismo urbano, el mercado inmobiliario ha resurgido como una fuerza determinante del proceso de coordinación social del uso del suelo y la producción de estructura intraurbana. Es el retorno de la "mano invisible" del mercado. En este artículo se analiza la relación entre la producción de estructura urbana y el funcionamiento del mercado inmobiliario en América Latina, tanto en su versión formal como en la informal. La hipótesis de trabajo es que las ciudades latinoamericanas, comparadas con los dos modelos tradicionales (la urbe compacta mediterránea, y la difusa anglosajona, muestran una estructura urbana particular. En ellas, el funcionamiento de los mercados del suelo produce simultáneamente una estructura urbana compacta y difusa. Es a esta estructura, característica de las grandes urbes latinoamericanas, que llamamos ciudad "com-fusa".With the crisis of urban Fordism, the real estate market has reemerged as a determining force in the social coordination process of land use and in the production of intra-urban structure. It has been the return of the "invisible hand" of the market. This paper presents an analysis of the relationship between the production of urban structure and the functioning modes of formal and informal land markets in Latin America. It proposes the hypothesis that, compared to the two traditional models (compact Mediterranean cities and the Anglo-Saxon diffused cities, Latin American cities exhibit a particular urban structure. In these cities, the functioning of land markets produces simultaneously a compact and a diffused urban structure. This urban structure, characteristic of large Latin American cities, we designate as the "Com-Fused" City.

Plastic surgery marketing in a generation of "tweeting".

Wong, Wendy W; Gupta, Subhas C

2011-11-01

"Social media" describes interactive communication through Web-based technologies. It has become an everyday part of modern life, yet there is a lack of research regarding its impact on plastic surgery practice. The authors evaluate and compare the prevalence of classic marketing methods and social media in plastic surgery. The Web sites of aesthetic surgeons from seven US cities were compared and evaluated for the existence of Facebook, Twitter, or MySpace links and promotions. To find the sites, the authors conducted a Google search for the phrase "plastic surgery" with the name of each city to be studied: Beverly Hills, California; Dallas, Texas; Houston, Texas; Las Vegas, Nevada; Miami, Florida; New York City, New York; and San Francisco, California. The trends of social networking memberships were also studied in each of these cities. In comparison to aesthetic surgeons practicing in other cities, those in Miami, Florida, favored social media the most, with 50% promoting a Facebook page and 46% promoting Twitter. Fifty-six percent of New York City aesthetic surgeons promoted their featured articles in magazines and newspapers, whereas 54% of Beverly Hills aesthetic surgeons promoted their television appearances. An increase in the number of new Facebook memberships among cosmetic providers in the seven cities began in October 2008 and reached a peak in October, November, and December 2009, with subsequent stabilization. The increase in the number of new Twitter memberships began in July 2008 and remained at a steady rate of approximately 15 new memberships every three months. Social media may seem like a new and unique communication tool, but it is important to preserve professionalism and apply traditional Web site-building ethics and principles to these sites. We can expect continued growth in plastic surgeons' utilization of these networks to enhance their practices and possibly to launch direct marketing campaigns.

Community Policing in Latin America: Lessons from Mexico City

Directory of Open Access Journals (Sweden)

Markus-Michael Müller

2010-04-01

Full Text Available Community policing programmes are widely perceived and promoted as an important solution for the pressing problems of insecurity in contemporary Latin American cities, and for improving citizen-police relationships. By drawing on the results of empirical fieldwork conducted in Mexico City, the article presents a critical analysis of the local community policing effort. The article demonstrates that this policing effort is overly determined by a local context, characterized by clientelism, political factionalism and police corruption, which therefore renders its contribution to a sustainable improvement of local accountability and police legitimacy unlikely. Against this background the article calls for more empirical studies on this topic and a greater sensitivity for the embeddedness of policing programmes within a wider political context.    Resumen: Colaboración ciudadana en América Latina: Lecciones de Ciudad de México  Los programas de colaboración ciudadana son ampliamente percibidos y presentados como una importante solución para los apremiantes problemas de inseguridad en las ciudades latinoamericanas de hoy, y para mejorar las relaciones entre la ciudadanía y la policía. Basándonos en los resultados de trabajo de campo realizado en Ciudad de México, en el presente artículo se ofrece un análisis crítico del programa local de policía comunitaria y se demuestra que está excesivamente determinado por un contexto local caracterizado por el clientelismo, las lealtades políticas y la corrupción policial. Por eso, el aporte del programa a un mejoramiento sustentable de la rendición de cuentas local y de legitimidad policial es improbable. Contra este telón de fondo, en el artículo se demandan más estudios empíricos sobre el tema y una mayor sensibilidad para la integración de los programas de policía comunitaria dentro de un contexto político más amplio.

CityGML - Interoperable semantic 3D city models

Science.gov (United States)

Gröger, Gerhard; Plümer, Lutz

2012-07-01

CityGML is the international standard of the Open Geospatial Consortium (OGC) for the representation and exchange of 3D city models. It defines the three-dimensional geometry, topology, semantics and appearance of the most relevant topographic objects in urban or regional contexts. These definitions are provided in different, well-defined Levels-of-Detail (multiresolution model). The focus of CityGML is on the semantical aspects of 3D city models, its structures, taxonomies and aggregations, allowing users to employ virtual 3D city models for advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. This is in contrast to purely geometrical/graphical models such as KML, VRML, or X3D, which do not provide sufficient semantics. CityGML is based on the Geography Markup Language (GML), which provides a standardized geometry model. Due to this model and its well-defined semantics and structures, CityGML facilitates interoperable data exchange in the context of geo web services and spatial data infrastructures. Since its standardization in 2008, CityGML has become used on a worldwide scale: tools from notable companies in the geospatial field provide CityGML interfaces.

1996-09-01

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.

Environment and sustainable development: The Yurimaguas City case Ambiente y desarrollo sostenible: el caso de la ciudad de Yurimaguas

Full Text Available Humanity is looking for solutions to the environmental degradation problem, which is generated by the economic and demographic growth, the indiscriminate use of resources, deforestation and pollution. The «sustainable development» concept, which considers social, economical and environmental aspects, was created twenty years ago, but it is still not producing the desired effects, and its application generates discussion, propositions and alternatives. As a geographer, I am interested especially in two aspects, which I consider, could lead the city development to sustainability: 1. adjust the development to the advantages and limitations of the natural media of the region where the city is located, and 2. that the urban activities do not transfer the costs and environmental problems to the surroundings of the city and to the future generations.In this paper I’ll try to put both postulations taking as an example the Yurimaguas city development. This city, located at a strategic point in the route between two oceans, has a past and a future linked to the conditions of the natural environment. The paper has an introduction where the theoretical aspects of both postulations are explained, then comes an analysis and discussion of the relationship between the natural environment and development of the Yurimaguas city, and finally some propositions are suggested to improve the quality of the city environment in order to lead it to a sustainable development.La humanidad entera busca una solución a los problemas de la degradación del ambiente, generada por el crecimiento económico y demográfico, el uso indiscriminado de los recursos, la deforestación y la contaminación.

Playable cities the city as a digital playground

CERN Document Server

2017-01-01

This book addresses the topic of playable cities, which use the ‘smartness’ of digital cities to offer their citizens playful events and activities. The contributions presented here examine various aspects of playable cities, including developments in pervasive and urban games, the use of urban data to design games and playful applications, architecture design and playability, and mischief and humor in playable cities. The smartness of digital cities can be found in the sensors and actuators that are embedded in their environment. This smartness allows them to monitor, anticipate and support our activities and increases the efficiency of the cities and our activities. These urban smart technologies can offer citizens playful interactions with streets, buildings, street furniture, traffic, public art and entertainment, large public displays and public events.

Influence of exposure differences on city-to-city heterogeneity ...

Science.gov (United States)

Multi-city population-based epidemiological studies have observed heterogeneity between city-specific fine particulate matter (PM2.5)-mortality effect estimates. These studies typically use ambient monitoring data as a surrogate for exposure leading to potential exposure misclassification. The level of exposure misclassification can differ by city affecting the observed health effect estimate. The objective of this analysis is to evaluate whether previously developed residential infiltration-based city clusters can explain city-to-city heterogeneity in PM2.5 mortality risk estimates. In a prior paper 94 cities were clustered based on residential infiltration factors (e.g. home age/size, prevalence of air conditioning (AC)), resulting in 5 clusters. For this analysis, the association between PM2.5 and all-cause mortality was first determined in 77 cities across the United States for 2001–2005. Next, a second stage analysis was conducted evaluating the influence of cluster assignment on heterogeneity in the risk estimates. Associations between a 2-day (lag 0–1 days) moving average of PM2.5 concentrations and non-accidental mortality were determined for each city. Estimated effects ranged from −3.2 to 5.1% with a pooled estimate of 0.33% (95% CI: 0.13, 0.53) increase in mortality per 10 μg/m3 increase in PM2.5. The second stage analysis determined that cluster assignment was marginally significant in explaining the city-to-city heterogeneity. The health effe

Resumen La realización de un diagnóstico del grado de madurez en el desarrollo de los Centros Comerciales Abiertos (CCA de las Ciudades Patrimonio de la Humanidad permite plantear nuevas propuestas, así como potenciales líneas de acción para su optimización y dinamización. Con este objeto, el trabajo plantea el uso de un Modelo de Evaluación contrastado que, siguiendo una metodología razonada y lógica, permite la evaluación y el análisis en profundidad del estado actual del CCA e identificar sus fortalezas y debilidades. La aplicación concreta del modelo a los CCA de Ciudades Patrimonio ha permitido obtener sus rasgos más característicos, así como sus peculiaridades. A partir de los resultados obtenidos se proponen recomendaciones para mejorar los puntos débiles identificados y se definen las principales líneas estratégicas que se recomendarían incluir en un plan de dinamización del comercio en los cascos históricos, lo que aportaría mayor competitividad y capacidad de creación de valor a esta forma de organización comercial. El trabajo pone de manifiesto que los “Centro Comercial Abiertos” presentan dos problemas fundamentales: dificultades de financiación y falta de representatividad. En este sentido, se propone emplear el modelo de los Business Improvement Districts (BID o Áreas para la Promoción de Iniciativa Empresarial (APIE como una fórmula de carácter público-privada interesante que permitiría solventar y reforzar los CCA agilizando los ritmos y las dinámicas de funcionamiento de las agrupaciones de comerciantes, y creando un marco estable para negociar y ejecutar las propuestas de los actores privados.

Métodos: Las defunciones ocurridas en residentes en las ciudades de Valencia y Alicante durante los períodos 1990-1992 y 1996-1998 se asignaron a los distritos municipales de residencia. La comparación entre los períodos de estudio o entre ciudades se ha realizado a través del riesgo relativo estimado mediante regresión de Poisson. Se calculó la razón comparativa de mortalidad (RCM según los 17 grandes grupos de la Clasificación Internacional de Enfermedades (9.ª revisión. Por distritos se han calculado en cada período de estudio las tasas ajustadas por el método directo, la razón de mortalidad estandarizada (RME, la razón de años potenciales de vida perdida (RAPVP y la esperanza de vida al nacimiento. Resultados: Los riesgos de muerte por todas las causas disminuyen del primer al segundo período tanto en varones, como en mujeres en ambas ciudades. La esperanza de vida aumenta significativamente en ambas ciudades en los varones, y en Valencia en las mujeres. La ciudad de Valencia presenta un mayor riesgo de muerte en ambos períodos. Algunos grupos de causas de muerte aumentan (grupos 5 y 6, que incluyen trastornos mentales y enfermedades del sistema nervioso y órganos de los sentidos. Por distritos, se observa una mayor variabilidad en Valencia --donde destacan los distritos 1 y 11 con un elevado riesgo de mortalidad-- que en Alicante. Conclusiones: El proceso de vigilancia de la mortalidad interna, por distritos, es reproducible. En la ciudad de Valencia existen diferencias en la mortalidad que se mantienen en el tiempo. La ciudad de Alicante presenta una menor variabilidad interna en sus indicadores de mortalidad.Objectives: To describe mortality patterns, in general and by

Se les aplicó un cuestionario domiciliario y de observación de sus condiciones de vida, con un muestreo por conveniencia no probabilística, y se eligió una muestra del 25%, para posteriormente realizarles entrevistas semiestructuradas. Encontramos que las explicaciones sobre los antecedentes, causas, síntomas y tratamientos del padecimiento están relacionadas con el contexto social en que vive cada uno de los enfermos, donde, a la vez que se mantienen explicaciones populares sobre la causalidad, se establecen prácticas de atención que combinan los tratamientos biomédicos con la herbolaria medicinal.

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

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.

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.

Paisajes del delito y la inseguridad en las ciudades intermedias

Full Text Available Until very recently, phenomena like delinquency were only considered dysfunctions of the system. However, nowadays this phenomenon has become inherent to its way of functioning. This dynamic is influenced by factors such as the increasing polarization of developed economies or the enormous masses of displaced people, due to either economic or political reasons, from developing countries who, in rich countries, often fall in situations of precariousness. In the following text we will see how all these pieces are interrelated in an intermediate city, and we will analyse the fluctuation of violent or intimidating thefts, as well as the most common places where these are committed.Si hasta hace bien poco se había considerado que fenómenos como la delincuencia no eran más que disfunciones del sistema, en el mundo en el que vivimos este fenómeno se ha convertido en inherente a su manera de funcionar. Influyen en esta dinámica factores como la polarización creciente de las economías desarrolladas o las ingentes masas de desplazados, ya sea por razones económicas o políticas, de países en vías de desarrollo que, en los países ricos, caen las más de las veces en la precariedad. En el texto que sigue se verá como se engarzan todas estas piezas en una ciudad intermedia y se analizará la fluctuación de los robos con violencia o intimidación, así como los lugares típicos en los que éstos se cometen.DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=1739302

The sandstone known as “Piedra Dorada”, or golden stone, is one of the most commonly used materials in the construction of many of the main historic buildings in the province of Jaén. Many examples can be found in the cities of Úbeda and Baeza, declared World Heritage Cities by UNESCO. A thorough characterization of their main varieties: “Viva”, “Franca” and “Jabaluna” has been done. Original quarry materials as well as samples of monuments have been analyzed. In this study we present a characterization of the mineralogical, textural and geochemistry features as well as the main physical properties of the varieties of “Piedra Dorada”. Furthermore, this research investigates in depth the main pathologies found in historic buildings in the cities mentioned above. We have established an order of quality of the varieties mentioned from the different parameters determined. We have also characterized the deterioration mechanisms amongst which are: biological colonization (lichens, algae, moss and higher plants), an increase in capillary action, surface deposits (salts and black crust) and anthropic factors such as leaks into the sewer network, absence of covers and downspouts, etc. This study has allowed us to know in detail one of the most important construction stones of Andalusia in order to ensure its durability for future year.

Urbanization leads to modifications of surface energy balance which governs the momentum, heat and mass transfer between urban canopy layer and the atmosphere, thus impacts dynamic processes in the urban ABL and ultimately influence the local, regional and even global climate. It is essential to obtain accurate urban ABL observations to enhance our understanding of land-atmosphere interaction process over the urban area and help to improve the prediction ability of numerical model. However, up to now, there are rarely observations in high latitude cities. In one of the highest cities in the world, Lhasa, Eddy Covariance (EC) measurements have been ongoing since 10 August 2016 and a Large Aperture Scintillometer (LAS) started to work on 12 November 2016, in addition to a UHI network which has been running since 2012. Taking advantage of these observations, this poster will estimate and analyze the surface energy balance in the winter of 2016 in Lhasa, with an emphasis on sensible heat flux. An analytical footprint model and the radiative surface temperature retrieved from Landsat 8 will be employed to compare EC and LAS measurements.

Serui City in Papua Province has many unique characters and must be maintained for the sake of the continuity of its identity. However, this city still lacks the facility and depend on other areas. Accordingly, it becomes vulnerable. The wholeness of the city is not just by having strong character but also having strength regarding vitality. The loss of it can affect the character and even eliminate it. Cities and people have many similarities regarding character and vitality. Therefore, there is a chance to solve the problems in the city using the similar approach to treat the human. We called city personification methods as problem-solving to the city. It means that we treat the city as a human being so that the problem can be solved as the human’s treatment. The personification of this city is conducted because of the many treatments that have proven effective in humans and may also be powerful to manifest in city. The personification makes the design will only focus on the particular networks and not on the whole “body,” remain in the hope for strengthening (maintain and improve) the quality of wholeness (character and vitality) city which in this case is Serui.

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.

Branding Cities, Changing Societies

DEFF Research Database (Denmark)

Ooi, Can-Seng

Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

Smart cities present a substantial growth opportunity in the coming years. The role of GIS in the smart city ecosystem is to integrate different data acquired by sensors in real time and provide better decisions, more efficiency and improved collaboration. Semantically enriched vision of GIS will help evolve smart cities into tomorrow's much smarter cities since geospatial/location data and applications may be recognized as a key ingredient of smart city vision. However, it is need for the Geospatial Information communities to debate on "Is 3D Web and mobile GIS technology ready for smart cities?" This research places an emphasis on the challenges of virtual 3D city models on the road to smarter cities.
