    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.

  4. Business profile of metropolitan Las Vegas

    International Nuclear Information System (INIS)

    Boyle, M.R.

    1988-06-01

    This first report describes the present makeup of the Las Vegas metropolitan statistical area (MSA) economy and analyzes the climate for business expansion. The second report contains an assessment of the competitiveness of the area as a location for new or expanded facilities investment by companies in approximately 600 business groups. The third report projects Las Vegas' competitiveness at the start of the next century in the absence of a nuclear waste storage facility and then evaluates the potential impacts of siting that facility near Las Vegas on its ability to attract and retain business investment. The primary purpose of these reports is to contribute to the overall assessment of the environmental impact of the US Department of Energy's proposed action to build and operate an underground nuclear waste storage facility at Yucca Mountain. The first two reports also serve a second purpose -- they can be used by economic development organizations in the Las Vegas metropolitan area in their ongoing efforts to attract new business investment. Information contained in the business climate analysis found in this first report can be incorporated into marketing materials. The competitiveness assessment contained in the second report can be used by these organizations in identifying targets they wish to pursue

  5. Radionuclide content of Las Vegas wash sediments

    International Nuclear Information System (INIS)

    Rudin, M.J.; Meyers, A.M.; Johnson, W.H.

    1996-01-01

    The Las Vegas Wash is an excavated waterway channel which drains all surface water and effluent discharge from sewage-treatment facilities from the greater Las Vegas Metropolitan Area to Lake Mead. Runoff and erosion processes are expected to transport man-made radioactivity that was deposited over the past several decades in the Las Vegas Valley. Additionally, radionuclides disposed of via the city's sanitary system are expected to accumulate in the Wash sediments. Fine and coarse sediment samples were collected at 100 m intervals and analyzed to determine the distribution of alpha- and gamma-emitting radionuclides in the lower 5,500 in of the Las Vegas Wash. Results indicate little accumulation of long-lived fission products in upstream Wash sediments. However, trace amounts of fission products measured in downstream sediments suggest the resuspension and transport of radioactive particulate matter within the Wash. Levels of naturally-occurring radionuclides found in Wash sediments were found to be consistent with levels typically found in southeast Nevada soils

    2009-08-01

    Full Text Available This paper uses proprietary data from a blackjack table in Las Vegas to analyze how the expectation of regret affects peoples' decisions during gambles. Even among a group of people who choose to participate in a risk-taking activity, we find strong evidence of an economically significant omission bias: 80\\% of the mistakes at the table are caused by playing too conservatively, resulting in substantial monetary losses. This behavior is equally prevalent among large-stakes gamblers and does not change in the face of more complicated strategic decisions.

  12. The Las Vegas Strip as a Genuinely Invented Global Landscape

    Directory of Open Access Journals (Sweden)

    Daniel Ortega

    2004-12-01

    Full Text Available Las Vegas, Nevada, is typically recognised as a place via a single urban gesture, that gesture being Las Vegas Boulevard, which is more commonly referred to as "The Strip". In constructing a thesis around the theme, "Here or There? Interconnections between the Global and the Local", one cannot ignore the invitation to discuss globalisation and its effects on a particular local fabric. For the purpose of this text, globalisation can be thought of as what Carmona et al describe as an intricate series of events leading to the world "becoming increasingly interconnected, with centralised decision making exploiting economies of scale and standardisation" (2003: 101. The centralised decision-making process for The Strip is evident in the strategy to develop individually themed casino resorts along Las Vegas Boulevard that respond to a competitive economy, thus creating a newly standardised landscape. If we also understand that globalisation can be thought of as the development of an interconnected world where economic, political and cultural boundaries can be easily crossed, this work can begin to define how the Las Vegas Strip is a genuinely invented global landscape. This paper addresses the "here-ness" as well as the "there-ness" of The Strip, while offering a dialectical framework for establishing a meaning of place by having 'there' placed 'here'. By employing semiological interpretations of real landscapes from around the globe (for example, Venturi et al, 1972, The Strip becomes a newly invented landscape of "simulations" (Baudrillard, 1988. As such, The Strip acts as a narrative that forms a unique place, opening the door to questions of authenticity and identity. This paper concludes by focusing on the question of "Here or There?" as an appropriate deviation from the assumed role that the post-modern landscape of the Las Vegas Strip plays. This work is intended to be a point of departure from the frequent criticism of the Las Vegas Strip as

  13. The Strip: Las Vegas and the Symbolic Destruction of Spectacle

    OpenAIRE

    Al, Stefan Johannes

    2010-01-01

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

  14. Source Water Assessment for the Las Vegas Valley Surface Waters

    Science.gov (United States)

    Albuquerque, S. P.; Piechota, T. C.

    2003-12-01

    The 1996 amendment to the Safe Drinking Water Act of 1974 created the Source Water Assessment Program (SWAP) with an objective to evaluate potential sources of contamination to drinking water intakes. The development of a Source Water Assessment Plan for Las Vegas Valley surface water runoff into Lake Mead is important since it will guide future work on source water protection of the main source of water. The first step was the identification of the watershed boundary and source water protection area. Two protection zones were delineated. Zone A extends 500 ft around water bodies, and Zone B extends 3000 ft from the boundaries of Zone A. These Zones extend upstream to the limits of dry weather flows in the storm channels within the Las Vegas Valley. After the protection areas were identified, the potential sources of contamination in the protection area were inventoried. Field work was conducted to identify possible sources of contamination. A GIS coverage obtained from local data sources was used to identify the septic tank locations. Finally, the National Pollutant Discharge Elimination System (NPDES) Permits were obtained from the State of Nevada, and included in the inventory. After the inventory was completed, a level of risk was assigned to each potential contaminating activity (PCA). The contaminants of concern were grouped into five categories: volatile organic compounds (VOCs), synthetic organic compounds (SOCs), inorganic compounds (IOCs), microbiological, and radionuclides. The vulnerability of the water intake to each of the PCAs was assigned based on these five categories, and also on three other factors: the physical barrier effectiveness, the risk potential, and the time of travel. The vulnerability analysis shows that the PCAs with the highest vulnerability rating include septic systems, golf courses/parks, storm channels, gas stations, auto repair shops, construction, and the wastewater treatment plant discharges. Based on the current water quality

    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.

  18. 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

    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

    2017-12-01

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

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

    2006-01-01

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

    2007-01-01

    As part of the 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 an aerial radiological survey on December 11-12, 2007, with the purpose of mapping natural radiation background and locating any man-made radioactive sources. The survey covered 19.4 square miles (9.2 square miles over the downtown area of the City of North Las Vegas and 10.2 square miles over the Las Vegas Motor Speedway [LVMS]). The flight lines over the surveyed areas are presented in Figures 1 and 2. A total of four 2.5-hour-long flights were performed at an altitude of 150 ft above ground level (AGL) with 300 ft of flight line spacing. Water line and test line flights were conducted over the Lake Mead and Government Wash areas to ensure quality control of the data. 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. Data in the form of gamma energy spectra were collected continually (every second) over the course of the survey and were geo-referenced using a differential Global Positioning System. Collection of spectral data allows the system to distinguish between ordinary fluctuations in natural background radiation levels and the signature produced by man-made radioisotopes sources. Spectral data can also be used to identify specific radioactive isotopes. As a courtesy service with the approval of the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office, RSL-Nellis is providing this summary to the office of the Mayor of City of North Las Vegas and LVMS security along with the gross counts-based exposure rate and man-made counts maps

El gran formato del libro original (38x28cm se justificaba por la importancia del material gráfico desplegado, un ejercicio de análisis que aspiraba a descubrir nuevas técnicas de representación capaces de reproducir una realidad tan compleja sensorialmente como la de la ciudad de las Vegas. La drástica transformación, impulsada por los propios autores, suponía un abaratamiento y por tanto una mayor difusión del libro, pero sobretodo trataba de acabar con el conflicto entre su crítica al diseño Bauhaus y el diseño Bauhaus tardío del libro original, como señaló la propia Denise Scott Brown en el prologo de la edición revisada de 1977.

    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.

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

    The chemistry of technetium is being explored at the University of Nevada Las Vegas. Our goal is to investigate both the applied and fundamental aspects of technetium chemistry, with a special emphasis on synthesis, separations, and materials science. The synthetic chemistry focuses on metal-metal multiple bonding, oxides and halides. Synthesis and characterizations of (n-Bu 4 N) 2 Tc 2 X 8 , Tc 2 (O 2 CCH 3 ) 4 X 2 (X = Cl, Br), TcO 2 , Bi 2 Tc 2 O 7 , Bi 3 TcO 8 , TcBr 3 and TcBr 4 have been performed. The applied chemistry is related to the behavior of Tc in the UREX process. Separation of U/Tc has been conducted using anion exchange resin and metallic Tc waste form synthesized and characterized.

    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

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

    Ahmad, S.

    2007-05-01

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

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

    Full Text Available 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.

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

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

    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.

    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 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

    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

    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.

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

    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

    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

    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

    1981-01-01

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

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

    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.

    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.

    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{sub 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{sub 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{sub 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.

  5. 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.

However, there is scarce data about the typology and the physical and chemical properties of the soils that determine the agricultural potential of vegas sites. Sampling of the main horizons of 47 soil profiles was conducted throughout the area. The profiles were described in the field and consequently classified according to the soil typology system of the WRB (IUSS Working Group WRB, 2006. Analyses of bulk and particle densities, capillary water capacity, pH (H2O, pH (CaCl2, texture, organic material, C:N ratio, electrical conductivity, effective cation exchange capacity, N, P, Ca-Mg-K-Na, exchangeable Al,  extractable Al, sulfur SO4(2-, B, and micronutrients (Cu-Zn-Mn-Fe were carried out.  The most frequently recorded groups of soil types in the studied vegas were Histosols - peat soils (20 profiles, and Fluvisols (19. Gleysols (3, Vertisols (1, Regosols (3, Solonchaks (1 and Solonetzs (1 were detected with much less frequency. There is also considerable variability in soil properties among and within the groups of soil types. The principal differences between the Histosols and the Fluvisols are the content of organic matter (often peat, pH level (related to the absence/presence of carbonates and associated soil properties. Fluvisols are more susceptible to salinization under conditions of aridity, whereas the main threat to Histosols is artificial drainage.Las praderas húmedas (vegas de la zona de uso agropecuario de la Región de Magallanes y la Antártica Chilena son ecosistemas productivos e intensamente explotados.

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

    Full Text Available El sustantivo Tudía abarca un amplio abanico de acepciones ligadas todas ellas a nuestro medievo. Tudía es una advocación mariana que figura en las cantigas de Alfonso el Sabio, donde el rey nos dice que ya existía una iglesia con el mismo nombre. Además, Tudía nos sirve para denominar una leyenda, una vicaría de la Orden de Santiago y, como no, un topónimo serrano de Extremadura. Hablaremos aquí de estos y otros aspectos apoyándonos en la historia y en la literatura hasta ver su impronta en el teatro de Lope de Vega.The name «Tudía» covers a wide range of meaning, all them related to the Middle Ages. «Tudía» is one of the names of the Virgin included in the medieval poems to St. Mary written by Alfonso X. The Castilian king also mentions that there was already a church named after her. Moreover, «Tudía» is also used to refer to a leged, to a vicarage of St. James’s Order and, it is of course, a mountain place name from Extremadura. Here we will develop these and some others aspects having into account both history and literature and their influence on Lope de Vega’s theatre.

    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.

    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.

    Internet addiction is known to be associated with depression. The Internet Addiction Test (IAT) and the Center for Epidemiologic Studies Depression scale (CES-D) for depression were studied among non-selective methadone maintenance treatment patients from the United States (n = 164) and Israel (n = 113). Thirty percent were not exposed to the internet, and 2.9% (n = 8) had an "occasional/frequent problem." The IAT and CES-D scores correlated significantly (p = .03). The non-exposed group was older, less educated, and had more benzodiazepine abusers. Unlike other behavioral addictions that characterized these patients, the internet addiction problem is rare, but should not be ignored.

    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 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 (NOx, 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 Fpeak 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.

    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

    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

  5. 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

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'.

    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.

    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

    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

    2012-01-01

    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.

    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)

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.

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.

    en un espacio generado a partir de los componentes principales, las especies se agrupan de manera concordante con los gremios tróficos establecidos para esta comunidad. Se plantea la hipótesis de la reducción en los tamaños de las especies, a partir de los resultados del análisis discriminante entre las muestras de campo y las del Instituto de Ciencias Naturales, que datan de muestreos realizados entre 1964 y 1966, el cual separa los dos grupos con un grado alto de confianza.

  9. historia en el Inca Garcilaso de la Vega

    Directory of Open Access Journals (Sweden)

    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.

  10. VEGA, a small launch vehicle

    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.

One of special features is to investigate the effect of ambient pressure on FP release which has never been examined in previous studies. As the furnace structures, ZrO 2 , W or ThO 2 will be used depending on the experimental conditions. In the post-test measurement, off-line gamma spectrometry, metallography and the elemental analyses are scheduled with SEM/EPMA, SIMA and ICP-AES. The installation of test facility into the beta/gamma concrete No.5 cell at the Reactor Fuel Examination Facility (RFEF) will be finished soon and four experiments in a year are scheduled. The analyses will be conducted with the VICTORIA code to prepare the operational conditions and to evaluate the results. Preliminary fabrication of ThO 2 crucible and tube was mostly successful by using the centrifugal slip casting technique. The FP release from MOX fuel will also be investigated in future. (author)

  13. 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

    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.

    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.

    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.

    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

    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.

    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.

    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 la primera parte demuestro la autoría lopesca de la obra a partir de elementos internos del texto y de la relación que guarda el manuscrito con noticias proporcionadas por documentación de la época. En la segunda parte del artículo estudio las características más relevantes de esta comedia, destacando su inserción en el género de la comedia urbana, la subversión que se lleva a cabo de ciertos temas, como las jerarquías sociales o el honor, y el papel predominante que Lope concede a las mujeres en la trama de la obra.

    Full Text Available Este artículo expone los resultados preliminares de la investigación doctoral en Antropología, orientada a conocer la materialidad y la subjetividad del trabajo de los call centers en Chile. Un salario definido por metas inalcanzables, el maltrato, el cansancio de nuevo tipo, la doble extracción del valor productivo y reproductivo de las mujeres trabajadoras y su entorno familiar, la explotación de las capacidades subjetivas, entre otros aspectos, dan cuenta de las nuevas formas que asume la precarización del trabajo. Las fábricas de la charla en Chile son un claro ejemplo de las formas que asume la organización del trabajo en el escenario laboral contemporáneo.

    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.

    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.

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

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

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

    The Department of Energy, Golden Field Office, awarded a grant to the UNLV Research Foundation (UNLVRF) on August 1, 2005 to develop a solar and renewable energy information center. The Solar Technology Center (STC) is to be developed in two phases, with Phase I consisting of all activities necessary to determine feasibility of the project, including design and engineering, identification of land access issues and permitting necessary to determine project viability without permanently disturbing the project site, and completion of a National Environmental Policy Act (NEPA) Environmental Assessment. Phase II is the installation of infrastructure and related structures, which leads to commencement of operations of the STC. The STC is located in the Boulder City designated 3,000-acre Eldorado Valley Energy Zone, approximately 15 miles southwest of downtown Boulder City and fronting on Eldorado Valley Drive. The 33-acre vacant parcel has been leased to the Nevada Test Site Development Corporation (NTSDC) by Boulder City to accommodate a planned facility that will be synergistic with present and planned energy projects in the Zone. The parcel will be developed by the UNLVRF. The NTSDC is the economic development arm of the UNLVRF. UNLVRF will be the entity responsible for overseeing the lease and the development project to assure compliance with the lease stipulations established by Boulder City. The STC will be operated and maintained by University of Nevada, Las Vegas (UNLV) and its Center for Energy Research (UNLV-CER). Land parcels in the Eldorado Valley Energy Zone near the 33-acre lease are committed to the construction and operation of an electrical grid connected solar energy production facility. Other projects supporting renewable and solar technologies have been developed within the energy zone, with several more developments in the horizon.

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.

    2009-09-01

    In this article, I contrast conceptualizations of authoritative knowledge in pregnancy and birth between U.S. midwives and their Mexican immigrant clients at a religious birthing center in south Texas. Although the two groups share certain orientations to pregnancy management, essential differences in prenatal care and birth epistemologies underscore distinct social and economic positions. I use narrative data to document and explain these differences, which throw into relief the hierarchies of identity and need that structure immigrant women's reproductive experiences. Unveiling the different epistemologies can also help to explain sometimes radically divergent ideas that have impacted the very survivability of the birthing center. By focusing on Mexican immigrant women's reproductive decision making in an alternative birthing center, this analysis responds to feminists' call to look to the margins to understand the diversity of women's responses to what Rapp and Ginsburg have called "stratified reproduction".

    1993-10-01

    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

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

    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.

  7. Health effects from exposure to atmospheric mineral dust near Las Vegas, NV, USA

    Directory of Open Access Journals (Sweden)

    Deborah E. Keil

    Full Text Available Desert areas are usually characterized by a continuous deposition of fine airborne particles. Over time, this process results in the accumulation of silt and clay on desert surfaces. We evaluated health effects associated with regional atmospheric dust, or geogenic dust, deposited on surfaces in the Nellis Dunes Recreation Area (NDRA in Clark County, Nevada, a popular off-road vehicle (ORV recreational site frequented daily by riders, families, and day campers. Because of atmospheric mixing and the mostly regional origin of the accumulated particles, the re-suspended airborne dust is composed of a complex mixture of minerals and metals including aluminum, vanadium, chromium, manganese, iron, cobalt, copper, zinc, arsenic, strontium, cesium, lead, uranium, and others. Geogenic dust with a median diameter of 4.1 μm was administered via oropharyngeal aspiration to female B6C3F1 mice at doses of 0.01 to 100 mg dust/kg body weight, four times, a week apart, for 28-days. Immuno- and neurotoxicological outcomes 24 h following the last exposure were evaluated. Antigen-specific IgM responses were dose-responsively suppressed at 0.1, 1.0, 10 and 100 mg/kg/day. Splenic and thymic lymphocytic subpopulations and natural killer cell activity also were significantly reduced. Antibodies against MBP, NF-68, and GFAP were not affected, while brain CD3+ T cells were decreased in number. A lowest observed adverse effect level (LOAEL of 0.1 mg/kg/day and a no observed adverse effect level (NOAEL of 0.01 mg/kg/day were derived based on the antigen-specific IgM responses.

    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.

    Setzman, E.; Braennstroem-Norberg, B.M.; Rosen-Lidholm, S.

    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

    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

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.

  6. 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.

    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

    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.

    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.

    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)

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.

    The report includes a review of the current state-of-the-art of dry-cooling technology for industrial and power-generating facilities and an evaluation of its technical potential and cost for large nuclear power plants. Criteria are formulated for coarse screening of the arid regions of the Western United States to select a surrogate site for more detailed site-specific analyses. The screening criteria included seismic considerations, existing transportation facilities, institutional and jurisdictional constraints, waste heat dissipation effects, water requirements, and ecologic and socioeconomic considerations. The Galt site near Las Vegas, Nevada was selected for the surrogate site analysis to assess important issues related to the construction and operation of twelve dry-cooled nuclear power plants at an arid location remote from major load centers. The assessment covers geotechnical, atmospheric and hydrologic considerations, special aspects of transporting large equipment overland to the site from seaports, analyses of potential transmission routes to major load centers, local institutional and taxing provisions, and ecologic and socioeconomic impacts

  8. 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 Wamp Spring section of the Bird Spring Group is subdivided into a basal platy limestone member, lower cliff-forming member, and upper cliff-forming member. Triticites, Schwagerina, and Schubertella kingi in the platy limestone member indicate an early Wolfcampian age. Schwagerina, Schubertella kingi, and a distinctive assemblage of brachiopods, similar to the West Texas fauna, indicate that the upper cliff-forming member is late Wolfcampian.

    2007-01-01

    Detection of point-source gamma signals from aerial measurements is complicated by widely varying terrestrial gamma backgrounds, since these variations frequently resemble signals from point-sources. Spectral stripping techniques have been very useful in separating man-made and natural radiation contributions which exist on Energy Research and Development Administration (ERDA) plant sites and other like facilities. However, these facilities are generally situated in desert areas or otherwise flat terrain with few man-made structures to disturb the natural background. It is of great interest to determine if the stripping technique can be successfully applied in populated areas where numerous man-made disturbances (houses, streets, yards, vehicles, etc.) exist

  20. Mobilization of Toxic Elements from an Abandoned Manganese Mine in the Arid Metropolitan Las Vegas (NV, USA Area

    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.

    Objectives. We examined the prevalence of work-related pain and injury and explored barriers to and experiences of reporting among workers. Methods. We surveyed 941 unionized hotel room cleaners about work-related pain, injury, disability, and reporting. Results. During the past 12 months, 75% of workers in our study experienced work-related pain, and 31% reported it to management; 20% filed claims for workers’ compensation as a result of work-related injury, and 35% of their claims were denied. Barriers to reporting injury included “It would be too much trouble” (43%), “I was afraid” (26%), and “I didn’t know how” (18%). An estimated 69% of medical costs were shifted from employers to workers. Conclusions. The reasons for underreporting and the extent of claim denial warrant further investigation. Implications for worker health and the precise quantification of shifting costs to workers also should be addressed. PMID:15727981

    Jamie C. DeWitt

    Full Text Available The specific health effects of direct inhalation of fine minerogenic dusts generated by natural soil surfaces remain poorly known and relatively little researched. To learn more about this exposure and its contribution to human health effects, we surveyed surface sediment and characterized dust from the Nellis Dunes Recreation Area (NDRA in Clark County, Nevada, a popular off-road vehicle (ORV recreational site. Dry drainage systems at NDRA are commonly used as natural trail systems for ORV recreation; these surfaces also are characterized by high concentrations of heavy metals. Geogenic dust with a median diameter of 4.05 μm, collected from drainage surfaces at NDRA contained a total elemental concentration of aluminum (79,651 μg/g, vanadium (100 μg/g, chromium (54 μg/g, manganese (753 μg/g, iron (33,266 μg/g, cobalt (14 μg/g, copper (37 μg/g zinc (135 μg/g, arsenic (71 μg/g, strontium (666 μg/g, cesium (15 μg/g, lead (34 μg/g, and uranium (54.9 μg/g. Adult female B6C3F1 mice exposed via oropharyngeal aspiration to 0.01–100 mg dust/kg body weight, four times, a week apart, for 28-days, were evaluated for immuno- and neurotoxicological outcomes 24 h after the last exposure. Antigen-specific IgM responses were dose-responsively suppressed at 0.1, 1.0, 10 and 100 mg/kg. Splenic lymphocytic subpopulations, hematological and clinical chemistry parameters were affected. In brain tissue, antibodies against NF-68, and GFAP were not affected, whereas IgM antibodies against MBP were reduced by 26.6% only in the highest dose group. A lowest observed adverse effect level (LOAEL of 0.1 mg/kg/day and a no observed adverse effect level (NOAEL of 0.01 mg/kg/day were derived based on the antigen primary IgM responses after subacute exposure to this geogenic dust.

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

    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.

    Introducción

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

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

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

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

    Antecedentes

    Ya desde los tiempos de Galeno, se sabía que los nervios eran los responsables de la rápida comunicación entre el cuerpo y el cerebro; el estudio de las sinapsis nos remonta de manera indirecta a

    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.

    Ahora, cuando la Corte Constitucional ha despenalizado al farmacodependiente por el consumo de drogas, conviene informar sobre las consecuencias perjudiciales de estas. A quienes deseen un conocimiento detallado al respecto, les recomiendo documentarse en “Enciclopedia de Psiquiatría”, publicada por “El Ateneo” en Buenos Aires.

    El Capítulo respectivo es del doctor Daniel L. Murguia. El denominador corriente de su abuso es sencillamente la dependencia, nombre propuesto por la Organización Mundial de la Salud, definido como el “estado psíquico y a veces físico causado por la interacción entre un organismo vivo y un fármaco”. Su carácter esencial es el impulso psicofísico a consumir el producto en forma continua o periódica, con el fin de experimentar los efectos que acarrea y evitar los malestares de su privación. Todas las drogas del respectivo género, consumidas a dosis altas, tienen efectos psicotóxicos que alteran la conducta y en algunos casos conducen a la muerte.

    Los expertos de la Organización Mundial califican las mencionadas sustancias en seis grupos, a saber:

    1. Morfina y opiáceas, los cuales crean dependencia física y psicológica, con tolerancia precoz, necesidad de aumentar las dosis y síndrome de abstinencia bastante peligroso. Entre los derivados se cuentan los siguientes: Hidromorfina (Dilaudid; oximorfina (Nurmophan; heroína,

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

    The 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

    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.

    Full Text Available Las listas de espera para recibir asistencia no urgente, en procesos diagnósticos o tratamientos, se dan fundamentalmente en los sistemas sanitarios de financiación pública como el español y otros muchos países europeos. Si éstas son moderadas, pueden ser útiles en el proceso de gestión de estos pacientes y son aceptadas por profesionales y usuarios. Las listas de espera para intervenciones quirúrgicas se pueden interpretar, erróneamente, como un simple desajuste entre la demanda y la oferta de un determinado procedimiento. Si así fuera, sólo deberíamos ir aumentando los recursos hasta terminar con las listas. Sin embargo, existen muchas evidencias de que el aumento aislado de los recursos no es la solución, ya que el tiempo medio de espera disminuye pero la lista se alarga por la cola. Serán necesarias, pues, otras medidas de gestión. Es necesario gestionar las listas, tanto en el plano social, de administración sanitaria y, sobre todo, en el ámbito del centro sanitario. La gestión clínica en los servicios y la gestión de cada profesional, con criterios de inclusión de evidencia científica en la indicación y en los resultados esperados de cada paciente (efectividad del procedimiento, y con criterios éticos y de eficiencia en la utilización de recursos, priorizando por gravedad, probabilidad de mejora y criterios sociales, es una obligación ineludible para mejorar el problema de las listas de espera. En este proceso de priorización, la sociedad debe tener su voz, su opinión, pues existen factores no médicos que pueden influir en la distribución y priorización de recursos. En este camino existen experiencias en otros países que deberíamos analizar. Finalmente, como decía Archie Cochrane¹, «todo tratamiento eficaz ha de ser gratuito», que, dicho de otra manera, sería: no está justificada la financiación en el sistema público de procedimientos que no aporten un beneficio significativo para el paciente

En el presente artículo buscamos analizar las relaciones entre ese Estado en formación y las instituciones locales destinadas a la atención de la salud y la educación, en comunidades del centro y sur bonaerenses, espacios no estudiados hasta el momento en esta clave, en el tránsito hacia el siglo XX cuando se resignificaron las funciones e importancia de organizaciones tradicionales como las abocadas a la práctica de la beneficencia, muchas de ellas de fuerte impronta católica.In the late 19th century and as part of the consolidation of political power in Argentina, we find a series of gaps left by the state, which were filled by the work of associations that emerged from civil society, in which the village women studied in this article acquired a noticeable presence. This article seeks to analyze relations between that nascent state and local institutions designed to provide health care and education in communities in the center and south of Buenos Aires. These spheres have not been studied in this sense to date, in the shift towards the 19th century when the functions and importance of traditional organizations such as charity organizations, many of which have a strong Catholic influence, were resignified.

    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 analyze the globular cluster (GC) systems in two very different galaxies, NGC 3115 and NGC 1399. With the papers of this series, we aim at highlighting common and different properties in the GC systems in galaxies covering a wide range of parameter space. We compare the GCs in NGC 3115 and NGC 1399 as derived from the analysis of one square degree u-, g-, and i-band images taken with the VST telescope as part of the VST early-type galaxy survey (VEGAS) and Fornax deep survey (FDS). We selected GC candidates using as reference the morpho-photometric and color properties of confirmed GCs. The surface density maps of GCs in NGC 3115 reveal a morphology similar to the light profile of field stars; the same is true when blue and red GCs are taken separately. The GC maps for NGC 1399 are richer in structure and confirm the existence of an intra-cluster GC component. We confirm the presence of a spatial offset in the NGC 1399 GC centroid and find that the centroid of the GCs for NGC 3115 coincides well with the galaxy center. Both GC systems show unambiguous color bimodality in (g - i) and (u - i); the color-color relations of the two GC systems are slightly different with NGC 3115 appearing more linear than NGC 1399. The azimuthal average of the radial density profiles in both galaxies reveals a larger spatial extent for the total GCs population with respect to the galaxy surface brightness profile. For both galaxies, the red GCs have radial density profiles compatible with the galaxy light profile, while the radial profiles for blue GCs are shallower. As for the specific frequency of GCs, SN, we find it is a factor of two higher in NGC 1399 than for NGC 3115; this is mainly the result of extra blue GCs. By inspecting the radial behavior of the specific frequency, SN(

    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

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 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

    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.

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.

    Full Text Available La Arcadia (1598 de Lope de Vega’s Arcadia (1598 was one of the most successful books in Lope’s already exceptional career, but, in spite of that success, modern critics insist in their criticism of the work, which they see as disorganized and superficial. In order to explain this contrast between these complaints and Arcadia’s success in Early-Modern times, we analyze one of the aspects of the work that critics reject the most: characterization, in particular of the two protagonists, the shepherds Anfriso and Belisarda, as well as some secondary characters. We claim that Golden Age readers must have appreciated the Arcadia’s characters partly because Lope designed them following a way of thinking typical of the time but profoundly strange to ours: moral theology’s casuistry and probabilism. In this context we examine the novel’s «cases» in detail, explaining how they must have been read and enjoyed at the time. In addition, this contextualization allows us to explore the reasons behind Lope’s interest for casuistry, and to relate this way of thinking to his experience as a playwright.La Arcadia (1598 de Lope de Vega fue uno de los libros más exitosos de la ya monstruosa carrera del Fénix, pero pese a ello la crítica actual insiste en criticar la obra tachándola de desorganizada y superficial. Para explicar el desfase entre estas críticas y el contrastable éxito de la Arcadia en su tiempo, este trabajo analiza uno de los aspectos más censurados por los estudiosos: la construcción de los personajes del libro, concretamente la de los dos protagonistas, los pastores Anfriso y Belisarda, y la de algunos personajes secundarios. En particular, proponemos que el lector áureo debió de apreciar los personajes de la Arcadia porque estaban diseñados de acuerdo con un hábito mental típico de la época, pero totalmente ajeno a nuestro modo de pensar, el casuismo y probabilismo de la teología moral.

    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.

    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.

    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.

    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.

    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.

    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.

Esta zona es objeto de estudios desde principios del siglo XX. Sin embargo los pulsos de la investigación han registrado etapas de abandono total y de intervenciones selectivas. Los investigadores han partido de los trabajos precedentes para explicar por extensión las modalidades de asentamiento en la totalidad del territorio norte y, sobre todo, del occidente montañoso, que era donde concentraban sus campañas. Esto acabó generando un cuadro de antecedentes desequilibrado y superficial en el conocimiento de dicha área, con implicaciones en el cuadro interpretativo general de la prehistoria local. En este caso, indagamos las posibles causas que dieron lugar a tal proceso, sus vínculos con los enfoques teóricos y metodologías dominantes a lo largo del siglo XX y su relación con la selección de zonas para llevar a cabo estudios de campo en el norte de la provincia. Reflexionamos críticamente sobre los alcances, límites y posibilidades que ofrece la región para profundizar los análisis arqueológicos del poblamiento prehispánico en relación con las condiciones del ambiente y los procesos históricos documentados, proponiendo discutir los enfoques que basan sus explicaciones en hechos dados por sentados y que merecerían antes una discusión en base a la evidencia disponible.

    Occupational injury rates among hotel workers exceed the national service sector average. This study assesses the prevalence of back and neck pain, and its associations with physical workload, ergonomic problems, and increasing work demands. Nine hundred forty-one unionized hotel room cleaners completed a survey about health and working conditions. Associations between job demands and pain were determined by logistic regression models adjusting for individual characteristics, cumulative work demands, care-taking responsibilities at home, and psychosocial job factors. The 1-month prevalence of severe bodily pain was 47% in general, 43% for neck, 59% for upper back, and 63% for low back pain. Workers in the highest exposure quartiles for physical workload and ergonomic problems were between 3.24 and 5.42 times more likely to report severe pain than workers in the lowest quartile. Adjusted odds ratios for work intensification ranged from 1.74 (upper back) to 2.33 (neck). Most room cleaners experience severe back or neck pain. Severe pain showed strong associations with physical workload, work intensification, and ergonomic problems.

    Globalisation processes and their effects on educational matters call for a thorough analysis of the relation between transnational policy-making and policy implementation at the local level, which is filtered by the state. Although a plethora of descriptive and analytical studies on adult...... education policies can be found in the scholarly literature, only sporadic analyses shed light on this relation. Accordingly, the scholarly community has recognised the importance of studying the growing phenomena of policy borrowing and policy learning (i.e. research of policy), as evidenced, for instance......, by the establishment in 2008 of a research network on Policy Study in Adult Education within the European Society for the Research on the Education of Adults (ESREA).

    Effective emergency preparedness and management is critical for a safe exploitation of nuclear installations like the Enusa fuel fabrication plant. In 2012, an important project was carried out at the plant which enlarged and remodeled the Emergency Room used until then to give response to the Internal Emergency Plan postulated scenarios. This project was motivated after carefully analyzing the results of audits, inspections and operation experience as well as after studying the conclusions of the Fukushima accident emergency management weaknesses. The new Center for Emergency Response, which hosts the plant control room, devoted to monitoring the plant safety systems on a constant basis, greatly improves both technical means available and operative procedures as well as human interactions during an emergency. This paper describes the most relevant technical features of this Center, the safety systems which support its operation and the emergency management process that takes place in it. (Author)

    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.

    1986-02-01

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

    1987-01-01

    The Land Analysis System (LAS) is a fully integrated digital analysis system designed to support remote sensing, image processing, and geographic information systems research. LAS is being developed through a cooperative effort between the National Aeronautics and Space Administration Goddard Space Flight Center and the U. S. Geological Survey Earth Resources Observation Systems (EROS) Data Center. LAS has over 275 analysis modules capable to performing input and output, radiometric correction, geometric registration, signal processing, logical operations, data transformation, classification, spatial analysis, nominal filtering, conversion between raster and vector data types, and display manipulation of image and ancillary data. LAS is currently implant using the Transportable Applications Executive (TAE). While TAE was designed primarily to be transportable, it still provides the necessary components for a standard user interface, terminal handling, input and output services, display management, and intersystem communications. With TAE the analyst uses the same interface to the processing modules regardless of the host computer or operating system. LAS was originally implemented at EROS on a Digital Equipment Corporation computer system under the Virtual Memorial System operating system with DeAnza displays and is presently being converted to run on a Gould Power Node and Sun workstation under the Berkeley System Distribution UNIX operating system.

    ácticas se vinculan a la responsabilidad social, a la sustentabilidad y a la ecología, como esencia de las acciones humanas para la conducción de las prácticas de gestión.This article aims at reflecting on nursing best practices and these practices as a perspective of systemizing care. Quality of nursing becomes evident from management practices instituted as a result of its development throughout time. Thinkers of the management area have really influenced nursing, both at professional acting and theoretical basis levels. It is imperative that nursing comes closer to best practices, which are considered as a non linear manner of perceiving the world, where structuring of its actions is centered on complex perspective; the use of registers as a way for planning, organization and care to take effect, as well as professional identification with issues that transcend personal care and are closer to universal ethics. Best practices are linked to social responsibility, sustainability and ecology, as an essence of human actions to conduct management practices.

De manera complementaria, fueron además dispuestas en la tarea las características que en estudios relacionados habían sido reportadas como facilitadoras de ejecuciones efectivas, a saber: el uso de instrucciones inespecíficas, arreglos de estímulo de tres formas y dos colores y el entrenamiento concurrente de las relaciones. Ocho sujetos fueron distribuidos en cuatro grupos que variaron en la combinación de relaciones a entrenar. Los resultados mostraron que gran parte de los sujetos cumplieron con el criterio de efectividad en entrenamiento y en transferencia extramodal y extrarrelacional, siendo la relación de identidad la relación en la cual se presentaron ejecuciones perfectas, al margen de si ésta había sido entrenada o no. Se discuten los resultados en términos de velocidad de ajuste a las relaciones y de las configuraciones de la tarea que facilitaron mejores desempeños. Se proponen, además, posibles investigaciones que superen las limitaciones metodológicas encontradas en este estudio y que exploren posibles interacciones de las variables manipuladas con otras variables de interés.

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

    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».

Tal sucede frecuentemente con las hepatitis a virus, por ejemplo las que tratadas con un régimen alimenticio inadecuado, constituído casi siempre por dietas de hambre, se va a complicar más la situación. Otras veces se utilizan sistemáticamente los antibióticos de amplio espectro, los cuales son inútiles e inclusive desaconsejados por la posibilidad de producir fibrosis hepática.

Una de ellas se forma por los encuentros locales, nacionales e internacionales que sirvieron de plataforma para comunicar, entre mujeres, las propias necesidades para el desarrollo y la liberación de la injusticia, intolerancia y desdén. Las mujeres han luchado por medio de sindicatos y movimientos sociales para plantear justas demandas, entre otras, educación, igual salario por igual trabajo, bienestar, permiso de maternidad, cuidado infantil, autodeterminación, información sexual, igualdad en la participación política y liderazgo.

    La civilización medieval produjo los arquetipos y el impulso dinámico para las fuerzas principales del mundo moderno. Representa el período de gestación de la cultura moderna. La ciencia occidental se desarrolló en las redes de la erudición medieval que en el siglo XII eran las escuelas catedralicias. La catedral de Chartres, simboliza, históricamente los comienzos de nuestra era científica y tecnológica.

    En la escuela de Chartres se establecieron las bases filosóficas para el surgimiento de la ciencia medieval y la moderna. El estudio de la naturaleza se constituyó en disciplina por derecho propio. En Chartres, durante el siglo XII, el estudio de la ciencia obtuvo por primera vez una prioridad definitiva sobre la enseñanza de las artes liberales y los maestros lucharon por la instauración de osadas reformas en la educación superior general centrando el programa de estudios de ciencias naturales en el cuadrivio: aritmética, música (como matemáticas geometría y astronomía y no en las humanidades tradicionales del trivio: gramática, retórica y lógica.

    La escuela de Chartres desafiaba así a los 7 siglos de enseñanzas cristianas a cerca del lugar de la naturaleza en el esquema divino, contra todas las resistencias de las grandes escuelas catedralicias de Orleans, Saint Victor en París y Laon. El ser humano y el mundo eran una unidad en el pensamiento de Chartres; trivio y cuadrivio eran parte de un universo único.

Uno de dichos espacios con los que juega el autor es la propia ciudad de Madrid, la ciudad real que contiene el corral de comedias donde se lleva a cabo la representación y que, a su vez, es reproducida en ella. Este recurso consigue un efecto sugestivo y evocador en un momento histórico en el que el espectador teatral y la propia urbe están definiendo sus identidades moldeándose mutuamente. This paper analyzes the way in wich Lope de Vega combines up to four different dramatic space levels when writing his comedia entitled «Santiago el Verde» (1615. One of these spaces the playwright plays with is the city of Madrid itself, the city that actually contains the playhoyse where the performance is taking place and that, at the same time, it is being reproduced in it. This device generates a stimulating and a evocative effect in a historical time when the theatre spectator and the city itself are defining their identities by molding each other.

    Eso es precisamente lo que se quiere mostrar en este libro: las raíces hundidas en el pasado y los sorprendentes hallazgos de la modernidad de la centuria precedente, con algunos hechos importantes acaecidos en el siglo XIX.

    Los primeros datos conocidos comenzaron por las observaciones sobre animales y humanos castrados, sobre gigantes y enanos, diabéticos, cotudos y cretinos, y luego sobre las descripciones incipientes de los órganos endocrinos más grandes como el cuerpo tiroides, las cápsulas suprarrenales, testículos, ovarios y la glándula pituitaria. Personajes que podrían perfectamente provenir del país de Lilliput o de un circo del vecindario, tal era su extraña apariencia.

    Una eventual relación entre los casos clínicos mencionados y las glándulas se ignoraba casi totalmente, casi porque sí se sabía lo que ocurría a un animal o a un hombre castrado, antes y después de la pubertad.

El propio genoma humano, la clave de aquello que nos da caracteres especiales y únicos como especie que piensa, se analiza a sí misma y se comunica con especial finura, está entregando sus secretos a los sabios que lo estudian.

    Si eso fuera todo, podríamos celebrar la llegada de nuevo poder para ayudar a nuestros semejantes en el cuidado de su salud, la mejora en su calidad de vida, el combate contra la enfermedad. Pero, al tiempo con los conocimientos científicos y las novedades tecnológicas, han aparecido cambios sociales que construyen un escenario igualmente nuevo para el ejercicio de la Medicina y, al menos en nuestro país, un intento más o menos soterrado para privarnos de nuestra condición de profesionales y ponernos a desempeñar un oficio sujeto a condiciones de actividad comercial; esto, por razones obvias, nos causa profunda preocupación.

    Al estudiar la situación en Colombia durante los últimos ocho o diez años, hemos visto que es posible enfocar la Medicina de dos modos bien distintos:

    – Como un oficio, es decir, atendiendo sobre todo a la aplicación de conocimientos y habilidades para conseguir una “obra” que cumpla ciertas normas y llene las expectativas de quien “recibe” esa “obra”, que sería el cliente.

    Full Text Available RESUMEN: Los países de América Latina están afectados en diferentes aspectos por el tráfico de drogas. En especial, en los países andinos, esta actividad ha condicionado de manera decisiva el tipo de régimen democrático iniciado en algún caso en la década de 1980, como Perú o Bolivia, o el régimen colombiano. El autor califica a estos regímenes como narcodemocracias por los efectos del tráfico de drogas no sólo en el orden social y económico, que analiza de forma profunda, sino por la politización del narcotráfico. Las respuestas de las democracias han sido bien distintas en los tres casos analizados, afectando, sin embargo, en todos ellos, a la gobernabilidad de las mismas y a su legitimidad.ABSTRACT: Latin American countries are affected by narcotrafico in different aspects. Particularly, in Andean countries, this activity has deeply conditioned the type of democratic regime installed in some cases in the eighties, as Perou and Bolivia, or the colombian regimen. The author characterizes these regimes as narcodemocracias by effects of narcotrafico in them, not only in social and economic arenas, but also by the politization of narcotrafico. Responses of democracies have been very different in these cases analyzed in the article. Nevertheless, in all of them, governability and legitmity of democracy are affected.

    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

Se pone de manifiesto que tanto los eventos propios del desarrollo, como los accidentales, dan lugar a la aparición de crisis en la familia. Queda esclarecido, que no necesariamente han de tener implicaciones negativas para la familia. Se hace énfasis en la valoración del evento por la familia y su significación. Se destaca el papel de los recursos familiares como protectores y moduladores de las crisis. Por último se señalan algunos pasos a seguir en la intervención familiarWith this paper we intend to update the topic of the family crises. It is shown that the own events of development as well as the accidental ones bring about the appearance of crises in the family. It is made clear that they not always have negative implications for the family. Emphasis is made on the assessment of the event for the family and its significance. The role played by the family resources as protective and modulators of the crisis is stressed. Finally, some of the steps to be taken in family intervention are mentioned

    Full Text Available El término histiocitosis identifica un grupo de alteraciones que tienen en común la proliferación de células dendríticas (CD y los macrófagos, y se diagnostican más frecuentemente en niños. Dentro de las relacionadas con las CD las fundamentales son las histiocitosis a células de Langerhans (HCL. Las HCL tienen un comportamiento clínico muy variable, que puede ir desde una lesión que involucra un solo sitio o sistema hasta una enfermedad multisistémica. El tratamiento depende de la extensión del proceso. Una lesión única tiende a desaparecer espontáneamente. También la biopsia diagnóstica con o sin inyección de un esteroide puede iniciar la curación. Los pacientes con enfermedad multisistémica pueden beneficiarse con el tratamiento esteroideo y citostático o inclusive con el trasplante de células progenitoras hematopoyéticas. La histiocitosis sinusal con linfoadenopatías masivas o enfermedad de Rosai Dorfman se debe a la proliferación de los macrófagos, es de naturaleza benigna y usualmente autolimitada. Afecta sobre todo a niños y adultos jóvenes. La linfohistiocitosis hemofagocítica también se produce por la proliferación de los macrófagos y es una enfermedad rara con una alta mortalidad. Puede ser familiar (autosómica recesiva o secundaria a infecciones virales. Esta última forma se presenta más frecuentemente en el lactante pequeño.

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

    Full Text Available Tras un somero recordatorio del hecho, a menudo olvidado, de que la cultura no es una realidad social sino tan solo un concepto, el artículo pretende argumentar en pro de la inexistencia de tal entidad (a pesar de las apariencias. La pregunta principal a la que se intenta responder es cual es el papel ideológico que tiene la idea de cultura, es decir ¿qué efectos de construcción de realidad genera? Para ello se realiza una crítica del concepto y de sus usos argumentando que tanto el concepto como su uso cotidiano entrañan prácticas de clasificación y segregación. Finalmente se aboga por la caída en desuso del concepto y por nuevas formas de pensar la diversidad humana más acordes con la posibilidad de una ética situada.
