    Stable isotope data for the Hueco Bolson aquifer (Texas, USA and Chihuahua, Mexico) distinguish four water types. Two types relate to recharge from the Rio Grande: pre-dam (pre-1916) river water with oxygen-18 and deuterium (δ18O, δD, ‰) from (-11.9, -90) to (-10.1, -82), contrasts with present-day river water (-8.5, -74) to (-5.3, -56). Pre-dam water is found beneath the Rio Grande floodplain and Ciudad Juárez, and is mixed with post-dam river water beneath the floodplain. Two other types relate to recharge of local precipitation; evidence of temporal change of precipitation isotopes is present in both types. Recharge from the Franklin and Organ Mountains plots between (-10.9, -76) and (-8.5, -60) on the global meteoric water line (GMWL), and is found along the western side of the Hueco Bolson, north of the Rio Grande. Recharge from the Diablo Plateau plots on an evaporation trend originating on the GMWL near (-8.5, -58). This water is found in the southeastern Hueco Bolson, north of the river; evaporation may be related to slow recharge through fine-grained sediment. Pre-dam water, recognizable by isotope composition, provides information on groundwater residence times in this and other dammed river basins.

    The U.S. Geological Survey, in cooperation with the City of El Paso and the Texas Department of Water Resources, made a preliminary study of specific factors related to recharging the Hueco bolson in the northeast El Paso area with treated sewage effluent. The city is interested in the location and spacing of injection wells relative to (1) maintaining the injected effluent in the aquifer for a predetermined amount of time (residence time) before it is pumped out, (2) recovery by pumping of as much of the injected effluent as possible, and (3) the long-term effects of injection on water-level declines.

    The Hueco bolson aquifer is being pumped at increasing rates to supply water for El Paso, Texas, and Ciudad Juarez, Mexico. Water-use projections for 1984-2000 indicate that the upward trend in pumping rates probably will continue, which will put an increasing burden on the limited freshwater resources of the aquifer. Near El Paso, saline water in the Rio Grande alluvium overlies freshwater in bolson deposits. Withdrawal of ground water has created a large cone of depression in the water table that is centered approximately under the El Paso-Ciudad Juarez urban area. The maximum depth of this cone in January 1984 was about 140 feet below the pre-development (before 1903) water table.

  4. Isotopic and Hydraulic Head Evidence for Cross-formational Leakage of Saline Water From the Rio Grande Alluvium to the Hueco Bolson Aquifer, Trans-Pecos Texas

    The twin-cities of El Paso and Juarez share the water resources of the Hueco Bolson, a Tertiary and Quaternary basin fill aquifer that spans the international border. Artesian conditions existed in the El Paso-Juarez Valley during predevelopment times, and dilute groundwaters in the Hueco Bolson flowed upward and mixed with the mineralized water in the shallow Rio Grande alluvium (alluvial deposits less than 60 m thick). The hydraulic gradient has been reversed since predevelopment times by heavy municipal pumping in the Hueco Bolson aquifer, and many of the deeper wells in the El Paso-Juarez Valley have been retired due to salinity exceeding 1500 mg/L TDS. Previous studies based on groundwater modeling suggested that salinity increased in deeper wells due to induced leakage of saline water from the shallow Rio Grande alluvium. Hydrochemical, isotopic and hydraulic head data collected in this study support this model. Tritium levels in several deeper wells in the El Paso-Juarez Valley (screens set from 90 to 210 m) vary from 1.2 to 7.9 TU, indicating post-bomb water from leakage from the Rio Grande and Rio Grande alluvium. The hydraulic head gradient is oriented vertically downward between the alluvial and bolson aquifers, reaching 0.14 (27 m/189 m) in one well nest. Groundwater from the same well nest gives δ18O and δ2H values plotting along a mixing curve, representing evaporated and saline waters in shallow alluvial wells (-7.2 to -8.3 δ18O \\permil, -66 to -71 δ2H \\permil), meteoric and dilute waters in the deepest bolson well (-10.7 δ18O \\permil, -76 δ2H \\permil), and intermediate and mixed saline water in middle bolson wells (-9.8 to -10.3 δ18O \\permil, -76 to -77 δ2H \\permil).

    The Hueco and southern Mesilla bolsons are the primary groundwater source for much of the El Paso/Ciudad Juarez metropolitan region of over 1 million residents. The bolsons lie at the point where the strike of the southern Rio Grande rift changes from north-south to northwest-southeast, likely due to its interaction with pre-existing Mesozoic and Paleozoic structures. Tectonic activity continues with recent (< 750,000 years) movement along basin bounding and low level (M<4) seismicity. Over the past 4 years we have been using a conjunction of microgravity, magnetic, water well logs and electrical resistivity studies to image the complex structure of these basins within a heavily urbanized environment. These studies suggest the presence of several northwest-southeast striking cross faults within the southern Mesilla Bolson as well as an extensive subsurface andesite body related to the Cristo Rey laccolith. Intrabasin faults in the Hueco Bolson appear to cut the basin into at least 3 smaller subbasins and to control the boundary between fresh and saline water within the aquifer system beneath El Paso. We are also able to trace the East Franklins Mountain fault (last movement < 15,000 ya) at least 15 km south of the U.S.-Mexico border.

  6. Geochemical studies of backfill aggregates, lake sediment cores and the Hueco Bolson Aquifer

    Thapalia, Anita

    This dissertation comprises of three different researches that focuses on the application of geochemistry from aggregates, lake sediment cores and Hueco Bolson Aquifer. Each study is independent and presented in the publication format. The first chapter is already published and the second chapter is in revision phase. Overall, three studies measure the large scale (field) as well as bench scale (lab) water-rock interactions influenced by the climatic and anthropogenic factors spans from the field of environmental geology to civil engineering. The first chapter of this dissertation addresses the chemical evaluation of coarse aggregates from six different quarries in Texas. The goal of this work is to find out the best geochemical methods for assessing the corrosion potential of coarse aggregates prior to their use in mechanically stabilized earth walls. Electrochemical parameters help to define the corrosion potential of aggregates following two different leaching protocols. Testing the coarse and fine aggregates demonstrate the chemical difference due to size-related kinetic leaching effects. Field fines also show different chemistry than the bulk rock indicating the weathering impact on carbonate rocks. The second chapter investigates zinc (Zn) isotopic signatures from eight lake sediment cores collected both from pristine lakes and those impacted by urban anthropogenic contamination. Zinc from the natural weathering of rocks and anthropogenic atmospheric pollutants are transported to these lakes and the signatures are recorded in the sediments. Isotopic analysis of core samples provides the signature of anthropogenic contamination sources. Dated sediment core and isotopic analysis can identify Zn inputs that are correlated to the landuse and population change of the watersheds. Comparison of isotopic data from both pristine and urban lake sediment core also serves as an analog in other lake sediment cores in the world. The third chapter studies on Hueco Bolson

    The Hueco Bolson aquifer is the primary water resource for the cities of El Paso and Juarez. Identification of the primary groundwater recharge zones and the dynamics of salinization are needed in order to predict the impact of current and future development of water resources. Excessive withdrawal has resulted in a persistent increase in salinity, forcing the El Paso Water Utility (EPWU) to abandon several once highly productive wells. The mechanisms for this pumping induced salinization are not clear, but may include upward movement of deep saline groundwaters, lateral migration of saline waters from elsewhere in the aquifer and pumping induced leakage of saline waters from mud and clay layers. Isotopic and chemical analysis of groundwaters from a recently constructed well field with multiple discrete vertical zone samples has provided a unique opportunity to characterize these deep salinity sources and identify the primary mechanisms of pumping induced salinization. Analysis of O and H isotopes was used to delineate two primary recharge zones in the northern portion of the aquifer. The western section along the Franklin Mountains indicates a linear trend of oxygen/hydrogen isotope ratios indicative of mountain front recharge with highly evaporated waters at depth. The eastern portion closer to the center of the basin shows a more complex picture of shallow and deep evaporated waters, with a mixing zone of a less evaporated source at intermediate depth. Incorporation of anion ratios and S isotope data with that of these recharge zones indicates multiple sources of salinization. High anion ratios and S isotope values characteristic of deep saline waters appear at depths greater than 300 meters, with S isotope values higher than 9‰ and Cl/Br ratios greater than 10,000. Mixing trends of these highly saline deep waters appear at the lowest intervals of some wells above 300 meters, indicating upward movement of deep saline groundwaters as a possible source of

    Interest in alternative energy has encouraged the investigation of possible geothermal resources in Trans Pecos, Texas/New Mexico in an area of extensive Cenozoic volcanism with several hot springs. Geochemical analysis of groundwater samples resulted in the definition of two major areas of geothermal interest: the Hueco Bolson in northeastern El Paso County, and the Presidio Bolson. Regional temperature gradient measurements also supported the existence of anomalies in these places, and showed another smaller anomaly in the Finlay Mountains, Hudspeth County. Detailed geophysical and geochemical studies were conducted on these three targets.

  13. An Aquifer Storage and Recovery system with reclaimed wastewater to preserve native groundwater resources in El Paso, Texas.

    Sheng, Zhuping

    2005-06-01

    The traditional concept of Aquifer Storage and Recovery (ASR) has been emphasized and extensively applied for water resources conservation in arid and semi-arid regions using groundwater systems as introduced in Pyne's book titled Groundwater Recharge and Wells. This paper extends the ASR concept to an integrated level in which either treated or untreated surface water or reclaimed wastewater is stored in a suitable aquifer through a system of spreading basins, infiltration galleries and recharge wells; and part or all of the stored water is recovered through production wells, dual function recharge wells, or by streams receiving increased discharge from the surrounding recharged aquifer as needed. In this paper, the author uses the El Paso Water Utilities (EPWU) ASR system for injection of reclaimed wastewater into the Hueco Bolson aquifer as an example to address challenges and resolutions faced during the design and operation of an ASR system under a new ASR system definition. This new ASR system concept consists of four subsystems: source water, storage space-aquifer, recharge facilities and recovery facilities. Even though facing challenges, this system has successfully recharged approximately 74.7 million cubic meters (19.7 billion gallons) of reclaimed wastewater into the Hueco Bolson aquifer through 10 recharge wells in the last 18 years. This ASR system has served dual purposes: reuse of reclaimed wastewater to preserve native groundwater, and restoration of groundwater by artificial recharge of reclaimed wastewater into the Hueco Bolson aquifer.

    1996-01-01

    The Chromic Acid Pit site is an inactive waste disposal site that is regulated by the Resource Conservation and Recovery Act of 1976. The 2.2-cubic-yard cement-lined pit was operated from 1980 to 1983 by a contractor to the U.S. Army Air Defense Artillery Center and Fort Bliss. The pit, located on the Fort Bliss military reservation, in El Paso, Texas, was used for disposal and evaporation of chromic acid waste generated from chrome plating operations. The site was certified closed in 1989 and the Texas Natural Resources Conservation Commission issued Permit Number HW-50296 (U.S. Environmental Protection Agency Permit Number TX4213720101), which approved and implemented post-closure care for the Chromic Acid Pit site. In accordance with an approved post-closure plan, the U.S. Geological Survey is cooperating with the U.S. Army in evaluating hydrogeologic conditions and ground- water quality at the site. One upgradient and two downgradient ground-water monitoring wells were installed adjacent to the chromic acid pit by a private contractor. Quarterly ground-water sampling of these wells by the U.S. Geological Survey began in December 1993. The Chromic Acid Pit site is situated in the Hueco Bolson intermontane valley. The Hueco Bolson is a primary source of ground water in the El Paso area. City of El Paso and U.S. Army water-supply wells are located on all sides of the study area and are completed 600 to more than 1,200 feet below land surface. The ground-water level in the area of the Chromic Acid Pit site has declined about 25 feet from 1982 to 1993. Depth to water at the Chromic Acid Pit site in September 1994 was about 284 feet below land surface; ground-water flow is to the southeast. Ground-water samples collected from monitoring wells at the Chromic Acid Pit site contained dissolved-solids concentrations of 442 to 564 milligrams per liter. Nitrate as nitrogen concentrations ranged from 2.1 to 2.7 milligrams per liter; nitrite plus nitrate as nitrogen

    Cortes, Alejandra; Johannessona, Kevin H.; Kilroy, Kathryn C.; Barron, Luis E.

    Water samples were collected from a series of springs, pools, and canals within the Cuatro Ciénegas Bolson, Coahuila, México and analyzed for stable oxygen and hydrogen isotopes. The ?oxigen-18 values of these waters ranged from a low of -8.2 up to -5.7 , with a mean (+/- standard deviation) of -6.5 +/- 0.82 , whereas ?deuterium ranged from -52 to -43 , with a mean (+/- standard deviation) of - 46.6 +/- 3.2 . The majority of the water samples plot sub-parallel and beneath the local meteoric water line, with those sample collected furthest from spring-line exhibiting the most enriched ?oxigen-18 values. The stable isotope data indicate isotopic enrichment of groundwaters by evaporation following discharge and subsequent surface flow. The isotope data suggests that a considerable fraction of Cuatro Ciénegas groundwaters originate via local recharge. Those springs that issue from the western base of the Sierra de San Marcos mountain range are chiefly recharged within these mountains, whereas groundwaters discharging from Laguna Anteojo in the northern part of the bolson are more likely recharged within the higher San de la Madera mountain range. A preliminary water balance estimate, however, that interbas in flow must also contributes to the considerable groundwater discharge within the bolson.

    2007-05-01

    The Calingasta bolson is situated between the Frontal Cordillera and the Andean Precordillera from 31° to 32° south latitude and 69° 20' to 69° 45' West longitude. Its average elevation is about 1600 m a.s.l. The seismic information indicates that the eastern margin of this tectonic depression was affected by convergence during the latest tertiary and the quaternary. The depositional mesozoic sequences in this bolson lie on a strong angular unconformity evidenced by a marked lithologic and structural change. These deposits triassic in age occur in remnants of continental half-grabens formed by rifting that gave rise to NNW-SSE trending basins with rapid subsidence (Kokogian et al., 1999). These rift basins are coeval to the triassic depocenters in the oil producing Cuyana basin . Contemporary marine sedimentation is restricted to the Chilean territory, that is, to the west of the Frontal Cordillera, where narrow troughs were opened to the NW as marine embayments. In the Calingasta bolson, the outcropping triassic deposits were laid mainly in fluvial and lacustrine environments and are exposed along the western flank of the Precordillera, as observed at the latitude of the locality of Hilario, among other localities. The bolson can be considered as a ramp basin formed between the Precodillera and the Frontal Cordillera, limited by antithetic overthrusts controlled by the inversion of the extensional faulting associated to the triassic fill of the basin (Rossello et al., 1996). A new gravimetric survey carried out in the Calingasta bolson area led to the generation of a recent gravimetric chart, which was processed with different modern analytical and interpretation techniques such as Analytic Signal, Tilt and its Gradient and Euler Deconvolution. The Bouguer anomaly chart was filtered with the upward continuation at 40 km. The negative Bouguer isoanomalies in the resulting residual anomaly chart describe the geometry of the Calingasta bolson.

    Full Text Available The Bolson tortoise, Gopherus flavomarginatus, occurs within a restricted geographical area in the Mexican Chihuahuan Desert. We analyzed the variation in surface microhabitat with relation to the burrow occupancy for this tortoise at the Mapimí Biosphere Reserve, Mexico. In summer 2010, we monitored burrow activity (active, inactive, or abandoned and measured environmental factors that might influence the burrow’s occupancy by tortoises (air temperature, relative humidity and substrate temperature, both inside and outside the burrow, and the plant cover around it. Discriminant analysis was used to identify the importance of these variables influencing burrow occupancy. Correlation and linear regression analyses were performed to quantify the relation between environmental factors in the sampled burrows. Results. Sixty-one burrows were identified at the Tortugas locality. The first function’s auto-value analysis indicates that this function explains 97.9% of the variation in burrow activity status; high occupancy scores were associated with low substrate temperature inside the burrow. Plant cover was inversely proportional to substrate temperature inside the burrow. These results suggest the importance the density of plants surrounding the tortoise’s burrow as a key factor influencing the burrow microclimate and occupancy by the tortoises. Conclusions. Gopherus flavomarginatus inhabits burrows, in part, based on microhabitat structure, with plant cover being a main factor influencing burrow occupancy. Our findings indicate that human land use and vegetation management are important for conserving Bolson tortoises, and for understanding habitat conditions necessary for the successful establishment of populations elsewhere.

  19. Using Range-Wide Abundance Modeling to Identify Key Conservation Areas for the Micro-Endemic Bolson Tortoise (Gopherus flavomarginatus.

    Directory of Open Access Journals (Sweden)

    Cinthya A Ureña-Aranda

    Full Text Available A widespread biogeographic pattern in nature is that population abundance is not uniform across the geographic range of species: most occurrence sites have relatively low numbers, whereas a few places contain orders of magnitude more individuals. The Bolson tortoise Gopherus flavomarginatus is endemic to a small region of the Chihuahuan Desert in Mexico, where habitat deterioration threatens this species with extinction. In this study we combined field burrows counts and the approach for modeling species abundance based on calculating the distance to the niche centroid to obtain range-wide abundance estimates. For the Bolson tortoise, we found a robust, negative relationship between observed burrows abundance and distance to the niche centroid, with a predictive capacity of 71%. Based on these results we identified four priority areas for the conservation of this microendemic and threatened tortoise. We conclude that this approach may be a useful approximation for identifying key areas for sampling and conservation efforts in elusive and rare species.

  2. Molluscs from the fossil site of "Lo Hueco" (Upper Cretaceous, Cuenca, Spain: Palaeoenvironmental and sequential implications

    Directory of Open Access Journals (Sweden)

    Callapez, P. M.

    2013-12-01

    Full Text Available In the exceptional site of "Lo Hueco" (Cuenca, Spain more than 8500 macroremains of plants, invertebrates and vertebrates, including titanosaur sauropod dinosaurs, have been collected in a succession of Upper Cretaceous "Garumn" facies. This work describes the molluscs found together, interpreting their palaeoenvironmental and sequential meaning. The sample is comparatively scarce due to the urgency of the excavation, and to constraints of the preservational scenario, seemingly not ideal for the fossilization of carbonated remains. Thus, the absence of well preserved shells has motivated the use of open nomenclature. Bivalves are recorded by unarticulated marly mudstone moulds of Margaritifera sp., Anodonta sp., ?Corbicula sp. and Pisidium sp., and most gastropods by gypsum moulds of Faunus sp. This association indicates a typical freshwater palaeofauna, where the presence of Melanopsidae gastropods can suggest the sporadic influence of moderately brackish-water episodes. These data confirm previous palaeoenvironmental interpretations proposed for the site. Additionally, the presence of the terrestrial gastropod Palaeocyclophorus sp. in underlying beds with high proportion of vegetal terrestrial organic matter, and situated over an important erosive discordance, has allowed to locate the beginning of the depositional sequence of "Lo Hueco".En el excepcional yacimiento paleontológico de "Lo Hueco" (Cuenca, España se han obtenido más de 8500 macrorrestos de plantas, invertebrados y vertebrados, incluyendo dinosaurios saurópodos titanosaurios, en una sección del Cretácico Superior en facies "Garumn". El presente trabajo describe los moluscos recogidos, interpretando su significado paleoambiental y secuencial. La muestra obtenida resulta relativamente reducida debido a la urgencia de la excavación, y a que las condiciones diagenéticas posiblemente no han favorecido la preservación de restos carbonatados.

    SummaryDetailed sets of tracer data (isotopes, salinity) and the results of MODFLOW modeling of water budgets provide an unprecedented opportunity for comparing modeling with field data in the area where the Rio Grande enters the Hueco Bolson basin of Texas and Chihuahua. Water from the Rio Grande has recharged the Hueco Bolson aquifer to a depth of 300 m below the surface in the El Paso-Ciudad Juárez area, the depth of infiltration corresponding to the depth of ancestral Rio Grande fluvial sediments. Groundwater beneath the river exhibits complex isotope and salinity stratification. Post-dam (post -1916, type A) river water has infiltrated to depths up to 80 m. Pre-dam (type B) river water has infiltrated to 300 m depth near downtown El Paso, and has mixed with, or been displaced further downstream by high-salinity native Hueco Bolson groundwater (type C, present in the basin north of the river). Salinity and isotope boundaries do not correspond precisely. Isotope stratification corresponds to water residence time and (for type C) to degree of evaporation; the highest salinities are associated with the most evaporated water. Modeling of water budgets in the basin fill beneath the river predicts present-day mixing of water types B and C where changing rates of pumping have caused a reversal of groundwater flow direction between El Paso and Ciudad Juárez, and deep recharge of type B water under conditions prevailing in the 1960s.

  6. REMUESTREO ESTRUCTURADO DE CONTORNOS DE HUECOS EN SUPERFICIES 3D DE OBJETOS DE FORMA LIBRE UTILIZANDO BRESENHAM

    Full Text Available La etapa de integración dentro del proceso de reconstrucción tridimensional de objetos de forma libre, requiere de la descripción, análisis y corrección de huecos en superficies 3D. Ciertas evaluaciones cuantitativas en este tema implican contar con conjuntos de datos espaciados de forma regular o contenidos en estructuras que garanticen dicha propiedad, por ejemplo voxels, octrees o mallas estructuradas. Lograr lo anterior requiere un proceso de re-muestreo de los puntos que conforman el contorno del hueco en la superficie 3D. En este trabajo se describe un método para obtener conjuntos estructurados de puntos, a partir de los datos de contornos de huecos en objetos de forma libre. El método inicia con el ajuste de una curva NURBS al conjunto inicial de puntos con el fin de asegurar la suavidad del contorno, de lo cual se obtiene un conjunto de puntos ajustados. Finalmente se utiliza el algoritmo de discretización de Bresenham para obtener el conjunto de puntos estructurados. Los resultados obtenidos muestran que el método desarrollado asegura que el conjunto final de puntos estructurados preserven la forma del contorno original con altos niveles de detalle.

    Full Text Available Forming openings in load-bearing brickwork is a very frequent operation when reforming old buildings. A correct solution requires the supporting structure, usually a steel portal frame, to be loaded by means of hydraulic jacks or some similar system. This step is normally omitted which gives rise to two different problems. Fistly, a delayed loosening of the unsupported area occurs and alarming cracks appear. Secondly and much more dangerous though not so apparent, is the overloading of certain areas of brickwork which can result in collapse due to bearing failure. This article considers the loading sequence for correctly opening up the brickwork. It a/so provides an original in situ method for estimating brickwork strengths as a complement to a visual inspection.La apertura de huecos en muros de carga es una operación frecuente en la reforma de edificios antiguos. Una correcta ejecución exige la puesta en carga de la estructura sustentante —normalmente un pórtico metálico— mediante gatos hidráulicos o algo similar, cosa que suele omitirse, dando lugar a dos problemas diferentes: uno, el desprendimiento diferido del área de descarga, con alarmantes fisuraciones y otro, sin efectos ostensibles, pero mucho más peligroso, como es la sobrecarga elevadísima en ciertas zonas de la fábrica que puede desembocar en un colapso por aplastamiento. Este artículo estudia y calcula la puesta en carga para una correcta ejecución del rasgado. También se ofrece un método, original, de estimación de calidades resistentes de las fábricas de ladrillo a rasgar, efectuando "in situ", que complementa las apreciaciones visuales.

    Full Text Available The Bolson tortoise (Gopherus flavomarginatus is the first species of extirpated megafauna to be repatriated into the United States. In September 2006, 30 individuals were translocated from Arizona to New Mexico with the long-term objective of restoring wild populations via captive propagation. We evaluated mtDNA sequences and allelic diversity among 11 microsatellite loci from the captive population and archived samples collected from wild individuals in Durango, Mexico (n = 28. Both populations exhibited very low genetic diversity and the captive population captured roughly 97.5% of the total wild diversity, making it a promising founder population. Genetic screening of other captive animals (n = 26 potentially suitable for reintroduction uncovered multiple hybrid G. flavomarginatus×G. polyphemus, which were ineligible for repatriation; only three of these individuals were verified as purebred G. flavomarginatus. We used these genetic data to inform mate pairing, reduce the potential for inbreeding and to monitor the maintenance of genetic diversity in the captive population. After six years of successful propagation, we analyzed the parentage of 241 hatchlings to assess the maintenance of genetic diversity. Not all adults contributed equally to successive generations. Most yearly cohorts of hatchlings failed to capture the diversity of the parental population. However, overlapping generations of tortoises helped to alleviate genetic loss because the entire six-year cohort of hatchlings contained the allelic diversity of the parental population. Polyandry and sperm storage occurred in the captives and future management strategies must consider such events.

  11. Titanosaur osteoderms from the Upper Cretaceous of Lo Hueco (Spain and their implications on the armor of Laurasian titanosaurs.

    Directory of Open Access Journals (Sweden)

    Daniel Vidal

    Full Text Available Titanosaurs are the only sauropod dinosaurs known to bear a dermal armor. Their osteoderms are relatively rare finds, with few more than a hundred specimens recovered worldwide. Also, little is known about their intra-individual, intra-specific or inter-specific variability. The macrovertebrate site of Lo Hueco (Upper Cretaceous; Cuenca, Spain has yielded several complete specimens of osteoderms, some associated with fairly articulated specimens. They are all variations of the morphotype known as bulb and root. The presence of only this morphotype in Europe, which is considered as the primitive condition among titanosaurs, seems to indicate that the known Upper Cretaceous Laurasian titanosaurs only bore these referred bulb and root osteoderms. An eliptic Fourier analysis on the outline of complete specimens from this morphotype reveals: i that they truly are part of a morphological cline; and ii the existence of a consistent correlation between the outline and the morphology of the bulb. Such variation along a cline is more consistent with intra-individual rather than inter-specific variation. The osteoderms associated with a single titanosaur individual from Lo Hueco reinforce this hypothesis.

    June 2007 was one of the wettest Junes on record for the state of Texas. Starting in late May, a string of low-pressure systems settled in over the U.S. Southern Plains and unleashed weeks of heavy to torrential rain. During the final week of June, much of Texas, Oklahoma, and Kansas received more than 330 percent of their average rainfall, said the National Climatic Data Center. The widespread heavy rain brought deadly floods to the entire region. On July 6, the Associated Press reported that every major river basin in Texas was at flood stage, an event that had not occurred since 1957. In addition to causing floods, the rains stimulated plant growth. The grassy, often arid, plains and plateaus of northern Mexico (bottom left), Texas (center), and New Mexico (top, left of center) burst to life with dense vegetation as this vegetation anomaly image shows. Regions where plants were growing more quickly or fuller than average are green, while areas where growth is below average are brown. Most of Texas is green, with a concentrated deep green, almost black, spot where vegetation growth was greatest. This area of western Texas is where the Pecos River flows out of New Mexico and heads southeast to the Rio Grande. In the darkest areas, vegetation was more than 100 percent above average. The brown spots in northeastern Texas and Oklahoma (top, right of center) may be areas where persistent clouds or water on the ground are hiding the plants from the satellite's view. Plants may also be growing less than average if swamped by too much rain. The image was made with data collected by the SPOT satellite between June 11 and June 20, 2007.

    Full Text Available En este trabajo se estudiaron las diversas ventajas constructivas que los ejes huecos presentan respecto a los sólidos, como la reducción de masa, mejor control de calidad, menores defectos en producción y facilidad de acoplamiento. De ahí su profusión en aplicaciones industriales, como ejes de ferrocarril, de reductores o en calandrias. Dichas ventajas se ven alteradas cuando el eje trabaja a fatiga en flexión rotativa y aparece una grieta sobre el mismo. Se comprobaron dichas ventajas y sus variaciones sobre un modelo inicial de una grieta plana superficial, y se ha observado que los ejes huecos resultan más perjudicados por estas grietas para ciertos valores del diámetro interior, mientras que para otros son ventajosos. Se concluye del presente estudio que puede establecerse un rango de valores para el diámetro interior de ejes huecos en el cual su aprovechamiento seríaóptimo.Palabras claves: ejes huecos y sólidos, propiedades estructurales, grieta plana.______________________________________________________________________________AbstractThis work studies the several advantages hollow axles show when compared to whole ones, such as lightness, better quality control, less manufacturing defects, coupling simplicity. Thence their being profusely employed in industry, in applications like railway axles, gearboxes or calenders. Theseadvantages are altered when the axle works under bending with rotation under fatigue and a crack appears on its surface. An analytical research upon a flat surface crack model has been made of these advantages and their variations and it has been observed that hollow axles suffer more from these cracks than whole ones for certain inner diameter values, whereas for others even less than whole ones. It can be deduced that a gap for the inner diameter can be ascertained, where the axle´s rendering would be optimal.Key words: hollowand whole axles, structural properties, flat crack.

    Helimak is an experimental approximation to the ideal cylindrical slab, a one-dimensional magnetized plasma with magnetic curvature and shear. The Texas Helimak real-izes this approximation to a large degree; the finite size of the device can be neglected for many phenomena. Specifically, the drift-wave turbulence characteristic of a slab is observed with scale lengths small compared with the device size. The device and the general features of its behavior are described here. The device is capable of studying drift-wave turbulence, scrape-off layer (SOL) turbulence, and the stabilization of turbulence by imposing velocity shear.

  19. A New Titanosaurian Braincase from the Cretaceous "Lo Hueco" Locality in Spain Sheds Light on Neuroanatomical Evolution within Titanosauria.

    Directory of Open Access Journals (Sweden)

    Fabien Knoll

    Full Text Available Despite continuous improvements, our knowledge of the neurocranial anatomy of sauropod dinosaurs as a whole is still poor, which is especially true for titanosaurians even though their postcranial remains are common in many Upper Cretaceous sites worldwide. Here we describe a braincase from the uppermost Cretaceous locality of ''Lo Hueco" in Spain that is one of the most complete titanosaurian braincases found so far in Europe. Although the titanosaurian Ampelosaurus sp. is known from the same locality, this specimen is clearly a distinct taxon and presents a number of occipital characters found in Antarctosaurus and Jainosaurus, which are approximately coeval taxa from southern Gondwana. The specimen was subjected to X-ray computed tomographic (CT scanning, allowing the generation of 3D renderings of the endocranial cavity enclosing the brain, cranial nerves, and blood vessels, as well as the labyrinth of the inner ear. These findings add considerable knowledge to the field of sauropod paleoneuroanatomy in general and titanosaurian endocast diversity in particular. Compared with that of many sauropodomorphs, the endocast appears only slightly flexed in lateral view and bears similarities (e.g., reduction of the rostral dural expansion with Gondwanan titanosaurians such as Jainosaurus, Bonatitan, and Antarctosaurus. The vestibular system of the inner ear is somewhat contracted (i.e., the radius of the semicircular canals is small, but less so than expected in derived titanosaurians. However, as far as the new specimen and Jainosaurus can be contrasted, and with the necessary caution due to the small sample of comparative data currently available, the two taxa appear more similar to one another in endocast morphology than to other titanosaurians. Recent phylogenetic analyses of titanosaurians have not included virtually any of the taxa under consideration here, and thus the phylogenetic position of the new Spanish titanosaurian--even its generic

Se han considerado diversas variaciones geométricas, como ejes huecos, y se determinó su incidencia sobre la geometría y la variación del peso de cada uno de los elementos constitutivos de los reductores afectados por el cambio geométrico de los árboles de salida. Para el caso de ejes macizos y huecos de igual sección circular y resistencia la disminución del área fue superior al 12% y la del módulo de resistencia a la flexión, del 11%. Para ejes de sección circular con chavetero el área disminuyó en más del 30%, mientras que el módulo de resistencia a la flexión, en 10%. Se concluye que el uso de árboles huecos con incrementos de hasta el 50% en su diámetro interior, no incide significativamente en la compacidad de reductores mecánicos de un paso.This work seeks to identify the incidence of the reduction of weight in integrated machine elements, as transmission axes, on its mechanical resistance and about the compactness of compound mechanical reducers for gear of a step.

It was observed that, for the case of solid axes and holes of same circular section and resistance the decrease of the area went superior to 12% and the one of the resistance module to the flexion, of 11%. For axes of circular section with wedge the area diminished in more than 30%, while the resistance module to the flexion, in 10%.

    2006-12-01

    The Hueco and Mesilla basins, located in the westernmost part of Texas and the southernmost part of New Mexico, are part of the Rio Grande Aquifer system. This aquifer system is the major water source for New Mexico, west Texas, and Mexico, including the cities of El Paso and Ciudad Juarez. The aquifer system lies within the Rio Grande Rift system, which spans the eastern edge of the Basin and Range province. Normal faults defining the Rio Grande Rift put structural and stratigraphic controls on aquifer systems such as those in the Mesilla and Hueco basins. These faults define stratigraphic controls on the aquifer by placing compacted rock next to unconsolidated and unsorted sediments, and act as conduits for water flow from the surface to the subsurface. We combine InSAR and gravity measurements to determine the location and geometry of subsurface faults within the basins. These faults can determine the shape and extent of observed land subsidence, which is a consequence of increased water pumping since the early 20th century. In addition, hydrologic information about the Rio Grande aquifer system, such as aquifer flow, compaction, and basin stratigraphy are compared with the InSAR results in order to determine how the subsidence is affecting the water table. Finally, subsidence patterns can indicate the presence and geometry of subsurface faults that may pose seismic hazards.

    The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers–Fort Worth District, the Texas Water Development Board, the Guadalupe-Blanco River Authority, and the Edwards Aquifer Authority, investigated streamflow gains and losses in the lower Guadalupe River Basin during four selected base-flow periods in March 2010, April 2011, August 2011, and, for a stream reach between Seguin, Tex., and Gonzales, Tex., in September 2012. Major sources of streamflow in this basin include releases from Canyon Lake, inflow from major springs (Comal Springs, San Marcos Springs, and Hueco Springs), and base flow (groundwater seeping to streams). Streamflow and spring-flow data were collected at 35 streamflow-gaging stations (including 6 deployed for this study) during the base-flow periods. This report describes streamflow in the lower Guadalupe River Basin, which consists of the Guadalupe River drainage basin downstream from Canyon Lake to the Guadalupe River near Tivoli, Tex.

    Full Text Available High-elevation groundwater sampled in 2003 in the Sacramento Mountains defines a line resembling an evaporation trend in δD-δ18O space. The trend results from recharge of winter precipitation into fractured limestone, with evaporation prior to recharge in broad mountain valleys. The same trend occurs in basin groundwater east and west of the range, indicating the high Sacramento Mountains as the principal regional water source, either direct from the limestone aquifers or from mountain-derived surface water. Tritium and carbon-14 indicate bulk residence times of a few decades in the high Sacramento Mountains and at Alamogordo, and of thousands of years south of Alamogordo and in the artesian aquifer near Artesia. Stable O, H isotope data fail to demonstrate the presence of Sacramento Mountains water in a saline aquifer of the Hueco Bolson (Texas.

    Socioeconomic position, racial/ethnic minority status, and other characteristics of the macro-environment may be important moderators of genetic influence on a wide array of psychosocial outcomes. Designed to maximize representation of low socioeconomic status families and racial/ethnic minorities, the Texas Twin Project is an ongoing study of school-age twins (preschool through 12th grade) enrolled in public schools in the Austin, Texas and Houston, Texas metropolitan areas. School rosters are used to identify twin families from a target population with sizable populations of African American (18%), Hispanic/Latino (48%), and non-Hispanic White (27%) children and adolescents, over half of whom meet US guidelines for classification as economically disadvantaged. Initial efforts have focused on a large-scale, family-based survey study involving both parent and child reports of personality, psychopathology, physical health, academic interests, parent-child relationships, and aspects of the home environment. In addition, the Texas Twin Project is the basis for an in-laboratory study of adolescent decision-making, delinquency, and substance use. Future directions include geographic expansion of the sample to the entire state of Texas (with a population of over 25 million) and genotyping of participating twins.

  20. Abandoned Texas oil fields

    Energy Technology Data Exchange (ETDEWEB)

    1980-12-01

    Data for Texas abandoned oil fields were primarily derived from two sources: (1) Texas Railroad Commission (TRRC), and (2) Dwight's ENERGYDATA. For purposes of this report, abandoned oil fields are defined as those fields that had no production during 1977. The TRRC OILMASTER computer tapes were used to identify these abandoned oil fields. The tapes also provided data on formation depth, gravity of oil production, location (both district and county), discovery date, and the cumulative production of the field since its discovery. In all, the computer tapes identified 9211 abandoned fields, most of which had less than 250,000 barrel cumulative production. This report focuses on the 676 abandoned onshore Texas oil fields that had cumulative production of over 250,000 barrels. The Dwight's ENERGYDATA computer tapes provided production histories for approximately two-thirds of the larger fields abandoned in 1966 and thereafter. Fields which ceased production prior to 1966 will show no production history nor abandonment date in this report. The Department of Energy hopes the general availability of these data will catalyze the private sector recovery of this unproduced resource.

  14. Chagas Disease Risk in Texas

    Science.gov (United States)

    Sarkar, Sahotra; Strutz, Stavana E.; Frank, David M.; Rivaldi, Chissa–Louise; Sissel, Blake; Sánchez–Cordero, Victor

    2010-01-01

    Background Chagas disease, caused by Trypanosoma cruzi, remains a serious public health concern in many areas of Latin America, including México. It is also endemic in Texas with an autochthonous canine cycle, abundant vectors (Triatoma species) in many counties, and established domestic and peridomestic cycles which make competent reservoirs available throughout the state. Yet, Chagas disease is not reportable in Texas, blood donor screening is not mandatory, and the serological profiles of human and canine populations remain unknown. The purpose of this analysis was to provide a formal risk assessment, including risk maps, which recommends the removal of these lacunae. Methods and Findings The spatial relative risk of the establishment of autochthonous Chagas disease cycles in Texas was assessed using a five–stage analysis. 1. Ecological risk for Chagas disease was established at a fine spatial resolution using a maximum entropy algorithm that takes as input occurrence points of vectors and environmental layers. The analysis was restricted to triatomine vector species for which new data were generated through field collection and through collation of post–1960 museum records in both México and the United States with sufficiently low georeferenced error to be admissible given the spatial resolution of the analysis (1 arc–minute). The new data extended the distribution of vector species to 10 new Texas counties. The models predicted that Triatoma gerstaeckeri has a large region of contiguous suitable habitat in the southern United States and México, T. lecticularia has a diffuse suitable habitat distribution along both coasts of the same region, and T. sanguisuga has a disjoint suitable habitat distribution along the coasts of the United States. The ecological risk is highest in south Texas. 2. Incidence–based relative risk was computed at the county level using the Bayesian Besag–York–Mollié model and post–1960 T. cruzi incidence data. This risk

  7. Red Tide off Texas Coast

    Science.gov (United States)

    2002-01-01

    Red tides (algae) bloomed late this summer along a 300-mile stretch of Texas' Gulf Coast, killing millions of fish and shellfish as well as making some people sick. State officials are calling this the worst red tide bloom in 14 years. The algae produces a poison that paralyzes fish and prevents them from breathing. There is concern that the deadly algae could impact or even wipe out this year's oyster harvest in Texas, which usually peaks during the Thanksgiving and Christmas holidays. The red tides were first observed off the Texas coast in mid-August and have been growing steadily in size ever since. Red tides tend to bloom and subside rapidly, depending upon changes in wind speed and direction, water temperature, salinity, and rainfall patterns (as the algae doesn't do as well in fresher water). This true-color image of the Texas Gulf Coast was acquired on September 29, 2000, by the Moderate-resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Terra spacecraft. The red tide can be seen as the dark reddish discoloration in the ocean running southwest to northeast along the coast. In this scene, the bloom appears to be concentrated north and east of Corpus Christi, just off Matagorda Island. The image was made at 500-meter resolution using a combination of MODIS' visible bands 1 (red), 4 (green), and 3 (blue). The city of Houston can be seen clearly as the large, greyish cluster of pixels to the north and west of Galveston Bay, which is about mid-way up the coastline in this image. Also visible in this image are plumes of smoke, perhaps wildfires, both to the north and northeast of Houston. For more information about red tides, refer to the Texas Red Tide Web site.

    A geologic and geochemical investigation of the Four Notch Roadless Area, Texas, was conducted. The area has a probable resource potential for oil and gas. There is, however, little promise for the occurrence of metallic mineral resources or other energy resources. Acquisition of seismic data and detailed comparisons with logs from wells from the vicinity of the Four Notch Roadless Area is necessary to better determine if the subsurface stratigraphy and structures are favorable for the accumulation of oil or gas.

    2000-01-01

    Murchison established the Permian System in the Ural Mountains of Russia in 1841. The first North American Permian fossils were discovered by Hall (1856) about 15 years later. The fossils, which were collected in New York State, were initially described as Carboniferous (Hall, 1856) but were subsequently recognized as Permian by Girty (1902). Benjamin F. Shumard (1858), however, was the first to place an unequivocal Permian designation on some North American fossils, which has been collected by his brother George G. Shumard from the Guadalupe Mountains in Texas. A half a century passed before Girty (1908) made known an extensive Guadalupian fauna, although his field work in Texas and his study of this fauna already lead him to propose a Guadalupian "period" (Girty, 1902). Girty's suggestion was accepted only when it was formalized as the Guadalupe Series by Adams et al. (1939). The "Guadalupian fauna" was based upon fossils that Girty collected in 1901 on an expedition headed by Robert T. Hill, a revered figure in Texas geology.

    The Law Enforcement technology development community has a growing interest in the technologies associated with gunshot detection and localization. These interests revolve around community-oriented policing. Technologies of interest include those associated with muzzle blast and bullet shockwave detection and the inter-netting of these acoustic sensors with electro-optic sensors. To date, no one sensor technology has proven totally effective for a complete solution. PSI has a muzzle blast detection and localization product which is wireless, highly mobile and reconfigurable, with a user-friendly laptop processor and display unit, which completed a one-year demonstration in Austin, Texas on July 6, 2002. This demonstration was conducted under a Cooperative Agreement with the National Institute of Justice and in cooperation with the Austin Police Department. This paper will discuss the details of the demonstrations, provide a summarized evaluation, elucidate the lessons learned, make recommendations for future deployments and discuss the developmental directions indicated for the future.

  9. Solar Leasing Summary, Houston Texas

    Energy Technology Data Exchange (ETDEWEB)

    Hammer, Mary [City of San Antonio, TX (United States)

    2013-02-14

    A relatively new option for homeowners looking to add solar to their home is the solar lease. At present, the solar lease option can be found in California, Arizona, Texas, Colorado, Hawaii, New York and Oregon. The most active companies currently offering solar leases are NRG Energy, Sungevity, Solar City and Sun Run. With the uncertainty and/or lack of subsidies the states participating in these programs have ebbed and flowed over the last few years. However, there is an expectation that in the current market solar leasing will make solar viable without the utility and federal subsidies. NRG Energy is currently testing this expectation in Houston, TX where currently no subsidies or incentives beyond the federal tax incentives, exist. Following is an explanation on the state of solar leasing in Houston, TX and explanation of the current financing options.

    1970-01-01

    Results of a survey of the parasites of the collared peccary (Dicotyles tajacu angulatus) in Texas are presented. Three ectoparasites, Amblyomma cajennense, Dermacentor variabilis, and Pulex porcinus were very common on peccaries from south Texas, but less common or absent in arid west Texas. Sucking lice, Pecaroecus javalii, were common on peccaries from west Texas, but were not found in south Texas. The known range of this louse in Texas is extended into the Big Bend area. Two ticks, Amnblyomma inornatumn and Haemaphysalis leporis-palustris, were found infrequently. Five of nine species of endoparasites found in this survey (Dirofilaria acutiuscula, Parabronema pecatriae, Parostertagia heterospiculum, Physocephalus sp., and Texicospirura turki) were prevalent. Three species, D. acutiuscula, Gongylonema baylisi, and Fascioloides magna, are reported from North American peccaries for the first time. The geographic distribution of the large American liver fluke, F. magna, coincided with an area where the parasite is enzootic in white-tailed deer. It is concluded that parasitism was of little importance in population control of peccaries during the period of the study.

  16. Rising Above the Storm: DIG TEXAS

    Science.gov (United States)

    Ellins, K. K.; Miller, K. C.; Bednarz, S. W.; Mosher, S.

    2011-12-01

    For a decade Texas educators, scientists and citizens have shown a commitment to earth science education through planning at the national and state levels, involvement in earth science curriculum and teacher professional development projects, and the creation of a model senior level capstone Earth and Space Science course first offered in 2010 - 2011. The Texas state standards for Earth and Space Science demonstrate a shift to rigorous content, career relevant skills and use of 21st century technology. Earth and Space Science standards also align with the Earth Science, Climate and Ocean Literacy framework documents. In spite of a decade of progress K-12 earth science education in Texas is in crisis. Many school districts do not offer Earth and Space Science, or are using the course as a contingency for students who fail core science subjects. The State Board for Educator Certification eliminated Texas' secondary earth science teacher certification in 2009, following the adoption of the new Earth and Space Science standards. This makes teachers with a composite teacher certification (biology, physics and chemistry) eligible to teach Earth and Space Science, as well other earth science courses (e.g., Aquatic Science, Environmental Systems/Science) even if they lack earth science content knowledge. Teaching materials recently adopted by the State Board of Education do not include Earth and Space Science resources. In July 2011 following significant budget cuts at the 20 Education Service Centers across Texas, the Texas Education Agency eliminated key staff positions in its curriculum division, including science. This "perfect storm" has created a unique opportunity for a university-based approach to confront the crisis in earth science education in Texas which the Diversity and Innovation in the Geosciences (DIG) TEXAS alliance aims to fulfill. Led by the Texas A&M University College of Geosciences and The University of Texas Jackson School of Geosciences, with

  19. Texas site selection and licensing status

    Energy Technology Data Exchange (ETDEWEB)

    Avant, R.V. Jr.

    1989-11-01

    Texas has identified a potential site in Hudspeth County in far West Texas near the town of Fort Hancock. Over the past year the Texas Low-Level Radioactive Waste Disposal Authority has been conducting detailed geology, hydrology, meteorology, soils, and flora and fauna evaluations. An authorization by the Board of Directors of the Authority to proceed with a license application, assuming that the detailed evaluation indicates that the site is suitable, is expected by September. A prototype license has been prepared in anticipation of the order to proceed with licensing, and the formal license application is expected to be submitted to the Texas Department of Health-Bureau of Radiation Control in December, meeting the license application milestone. Although site selection processes in all siting areas across the country have experienced organized opposition, El Paso County has funded a particularly well-organized, well-financed program to legally and technically stop consideration of the Fort Hancock site prior to the licensing process. Many procedural, regulatory, and technical issues have been raised which have required responses from the Authority in order to proceed with licensing. This has provided a unique perspective of what to expect from well-organized opposition at the licensing stage. This paper presents an update on the Texas siting activity with detailed information on the site evaluation and license application. Experience of dealing with issues raised by opposition relating to NRC guidelines and rules is also discussed.

  20. Wind data in Texas. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Nelson, V.; McGaughey, D.

    1980-08-01

    Two major objectives of the project reported were (1) to update Texas wind energy resource information and (2) prepare a Texas wind resource publication for use by the general public. Both of these objectives were viewed as having major benefit for the growth of wind energy utilization in Texas. Meteorological data on magnetic tapes for all the major National Weather Service stations (18) were obtained from Texas Natural Resources Information Systems (generally for the years 1961 to 1966). Windspeed, pressure, and temperature data were then used to tabulate windspeed histograms and to calculate the wind energy for each station. Average month and year windspeed histograms were also calculated. From this data, the State was divided into five regions depending on the availability of wind energy. The windspeed histograms for each region were combined with the power curve for fifteen commercially available wind turbines to calculate the average energy output per year. To help individuals assess the economic feasibility of acquiring wind turbines, cost and benefit factors for the wind turbines were calculated for the various regions of the State. Basically, the years to payback for the installed wind tubines were calculated for different electricity rates (3, 5, and 7 cents/kWh) and different carrying charges (11, 15, and 19%). The above information was incorporated into A Consumer's Guide for Wind Energy in Texas, which describes wind energy and power, wind turbines and their applications, economics, and tips on siting.

    2015-12-01

    From 7 March to 30 April 2014, NodalSeismic, Nanometrics, and IRIS PASSCAL conducted a collaborative, spatially-dense seismic survey with several thousand nodal short-period geophones complemented by a backbone array of broadband sensors near Sweetwater, Texas. This pilot project demonstrates the efficacy of industry and academic partnerships, and leveraged a larger, commercial 3D survey to collect passive source seismic recordings to image the subsurface. This innovative deployment of a large-N mixed-mode array allows industry to explore array geometries and investigate the value of broadband recordings, while affording academics a dense wavefield imaging capability and an operational model for high volume instrument deployment. The broadband array consists of 25 continuously-recording stations from IRIS PASSCAL and Nanometrics, with an array design that maximized recording of horizontal-traveling seismic energy for surface wave analysis over the primary target area with sufficient offset for imaging objectives at depth. In addition, 2639 FairfieldNodal Zland nodes from NodalSeismic were deployed in three sub-arrays: the outlier, backbone, and active source arrays. The backbone array consisted of 292 nodes that covered the entire survey area, while the outlier array consisted of 25 continuously-recording nodes distributed at a ~3 km distance away from the survey perimeter. Both the backbone and outlier array provide valuable constraints for the passive source portion of the analysis. This project serves as a learning platform to develop best practices in the support of large-N arrays with joint industry and academic expertise. Here we investigate lessons learned from a facility perspective, and present examples of data from the various sensors and array geometries. We will explore first-order results from local and teleseismic earthquakes, and show visualizations of the data across the array. Data are archived at the IRIS DMC under stations codes XB and 1B.

  12. Hydrogeology of Webb County, Texas

    Science.gov (United States)

    Lambert, Rebecca B.

    2004-01-01

    Introduction: Webb County, in semiarid South Texas on the U.S.-Mexico border, is a region confronted by increasing stresses on natural resources. Laredo (fig. 1), the largest city in Webb County (population 193,000 in 2000), was one of the 10 fastest-growing metropolitan areas in the country during 1990-2000 (Perry and Mackun, 2001). Commercial and industrial activities have expanded throughout the region to support the maquiladora industry (manufacturing plants in Mexico) along the border and other growth as a result of the passage of the North American Free Trade Agreement. The Rio Grande currently (2002) is the primary source of public water supply for Laredo and other cities along the border in Webb County (fig. 1). Other cities, such as Bruni and Mirando City in the southeastern part of the county, rely on ground-water supplies to meet municipal demands. Increased water demand associated with development and population growth in the region has increased the need for the City of Laredo and Webb County to evaluate alternative water sources to meet future demand. Possible options include (1) supplementing the surface-water supply with ground water, and (2) applying artificial storage and recovery (ASR) technology to recharge local aquifers. These options raise issues regarding the hydraulic capability of the aquifers to store economically substantial quantities of water, current or potential uses of the resource, and possible effects on the quality of water resulting from mixing ground water with alternative source waters. To address some of these issues, the U.S. Geological Survey (USGS), in cooperation with the City of Laredo, began a study in 1996 to assess the ground-water resources of Webb County. A hydrogeologic study was conducted to review and analyze available information on the hydrogeologic units (aquifers and confining units) in Webb County, to locate available wells in the region with water-level and water-quality information from the aquifers, and

    2009-01-01

    Raccoons (n=590) were collected from October 1999 to August 2003 from 35 counties across Texas, and gastrointestinal tracts were examined for helminth parasites. Prevalence was calculated and differences in mean abundance were examined among habitat ecoregions, age classes, and between sexes. Twenty different species of helminths (13 nematodes, two cestodes, two acanthocephalans, and three trematodes) were positively identified in the gastrointestinal tracts of 590 raccoons in Texas. Five of the 20 helminth species collected (Physaloptera rara, Placoconus lotoris, Molineus barbatus, Atriotaenia procyonis, and Macracanthorhynchus ingens) had a prevalence >20%. The total number of individuals of these five species (n=22,777) accounted for over 86% of the total number of individuals of all helminth species (n=26,426) collected. Subsequent analyses were based on these five helminths. Mean abundance differed among habitat ecoregions, age classes, and between sexes for all five parasites evaluated. This study is the most comprehensive statewide survey ever done of gastrointestinal helminths of raccoons across Texas. The five most prevalent helminths identified have all been reported in at least one previous survey, indicating that these parasites are not new to Texas and that raccoons are not naïve to the effects these parasites have on them. It may be helpful to wildlife rehabilitators, trappers, wildlife biologists, and other professionals to be aware of parasite abundance in raccoons from different areas of the state, as frequent human-raccoon interactions occur, and some of these parasites could be harmful to humans and domestic animals.

  18. Quantifying Potential Groundwater Recharge In South Texas

    Science.gov (United States)

    Basant, S.; Zhou, Y.; Leite, P. A.; Wilcox, B. P.

    2015-12-01

    Groundwater in South Texas is heavily relied on for human consumption and irrigation for food crops. Like most of the south west US, woody encroachment has altered the grassland ecosystems here too. While brush removal has been widely implemented in Texas with the objective of increasing groundwater recharge, the linkage between vegetation and groundwater recharge in South Texas is still unclear. Studies have been conducted to understand plant-root-water dynamics at the scale of plants. However, little work has been done to quantify the changes in soil water and deep percolation at the landscape scale. Modeling water flow through soil profiles can provide an estimate of the total water flowing into deep percolation. These models are especially powerful with parameterized and calibrated with long term soil water data. In this study we parameterize the HYDRUS soil water model using long term soil water data collected in Jim Wells County in South Texas. Soil water was measured at every 20 cm intervals up to a depth of 200 cm. The parameterized model will be used to simulate soil water dynamics under a variety of precipitation regimes ranging from well above normal to severe drought conditions. The results from the model will be compared with the changes in soil moisture profile observed in response to vegetation cover and treatments from a study in a similar. Comparative studies like this can be used to build new and strengthen existing hypotheses regarding deep percolation and the role of soil texture and vegetation in groundwater recharge.

  19. Creationism in the Grand Canyon, Texas Textbooks

    Science.gov (United States)

    Folger, Peter

    2004-01-01

    AGU President Bob Dickinson, together with presidents of six other scientific societies, have written to Joseph Alston, Superintendent of Grand Canyon National Park, pointing out that a creationist book, The Grand Canyon: A Different View, is being sold in bookstores within the borders of the park as a scientific explanation about Grand Canyon geologic history. President Dickinson's 16 December letter urges that Alston clearly separate The Grand Canyon: A Different View from books and materials that discuss the legitimate scientific understanding of the origin of the Grand Canyon. The letter warns the Park Service against giving the impression that it approves of the anti-science movement known as young-Earth creationism, or that it endorses the advancement of religious tenets disguised as science. The text of the letter is on AGU's Web site http://www.agu.org/sci_soc/policy/sci_pol.html. Also, this fall, AGU sent an alert to Texas members about efforts by intelligent design creationists aimed at weakening the teaching of biological evolution in textbooks used in Texas schools. The alert pointed scientists to a letter, drafted by AGU, together with the American Institute of Physics, the American Physical Society, the Optical Society of America, and the American Astronomical Society, that urged the Texas State Board of Education to adopt textbooks that presented only accepted, peer-reviewed science and pedagogical expertise. Over 550 scientists in Texas added their names to the letter (http://www.agu.org/sci_soc/policy/texas_textbooks.pdf ), sent to the Board of Education on 1 November prior to their vote to adopt a slate of new science textbooks. The Board voted 11-5 in favor of keeping the textbooks free of changes advocated by groups supporting intelligent design creationism.

  1. Underdiagnosis of dengue--Laredo, Texas, 1999.

    Science.gov (United States)

    2001-02-02

    Dengue outbreaks have been reported in communities along the Mexico-U.S. border since 1980; however, during 1987-July 1999, no cases were reported from Laredo, Texas (1999 population: 162,000). During January-July 1999, approximately 300-325 dengue cases were reported from Nuevo Laredo, Tamaulipas, Mexico (1999 population: 274,000), a city across the Rio Grande from Laredo. To determine whether undiagnosed or unreported dengue cases had occurred in Laredo, the Texas Department of Health (TDH) reviewed medical records from five Laredo health facilities (the two city hospitals and the three largest of five community clinics). This report summarizes the findings of the review, which indicated that during July 23-August 20, 1999, 50% of suspected case-patients had undiagnosed dengue infection. Recognition of the diagnosis of dengue can be improved through heightened surveillance, professional and public education, and prompt reporting of cases by the health-care providers to local or state health departments.

  2. Medicaid Expansion in Texas: What's at Stake?

    Science.gov (United States)

    Sommers, Benjamin D

    2016-04-01

    Texas is one of nearly 20 states yet to expand its Medicaid program under the Affordable Care Act (ACA), and is home to the largest number of uninsured Americans of any state in the country. For many of the state's 5 million uninsured, this decision has left them without an option for affordable health insurance. A comparison with other Southern states that have expanded Medicaid shows how this decision has left many low-income Texans less able to afford their medical bills, to pay for needed prescription drugs, and to obtain regular care for chronic conditions. These problems have been compounded by the state's opposition to outreach and enrollment assistance for many Texans who are eligible for coverage under the ACA. Ongoing efforts from stakeholders and consumer groups to persuade state leaders to expand coverage have significant implications for the well-being of millions of low-income adults in Texas.

    2016-06-01

    During a dengue epidemic in northern Mexico, enhanced surveillance identified 53 laboratory-positive cases in southern Texas; 26 (49%) patients acquired the infection locally, and 29 (55%) were hospitalized. Of 83 patient specimens that were initially IgM negative according to ELISA performed at a commercial laboratory, 14 (17%) were dengue virus positive by real-time reverse transcription PCR performed at the Centers for Disease Control and Prevention. Dengue virus types 1 and 3 were identified, and molecular phylogenetic analysis demonstrated close identity with viruses that had recently circulated in Mexico and Central America. Of 51 household members of 22 dengue case-patients who participated in household investigations, 6 (12%) had been recently infected with a dengue virus and reported no recent travel, suggesting intrahousehold transmission. One household member reported having a recent illness consistent with dengue. This outbreak reinforces emergence of dengue in southern Texas, particularly when incidence is high in northern Mexico.

  4. Wind/solar resource in Texas

    Energy Technology Data Exchange (ETDEWEB)

    Nelson, V.; Starcher, K.; Gaines, H. [West Texas A& M Univ., Canyon, TX (United States)

    1997-12-31

    Data are being collected at 17 sites to delineate a baseline for the wind and solar resource across Texas. Wind data are being collected at 10, 25, and 40 m (in some cases at 50 m) to determine wind shear and power at hub heights of large turbines. Many of the sites are located in areas of predicted terrain enhancement. The typical day in a month for power and wind turbine output was calculated for selected sites and combination of sites; distributed systems. Major result to date is that there is the possibility of load matching in South Texas during the summer months, even though the average values by month indicate a low wind potential.

    2010-09-01

    Although the multi-component weight loss supplement Redotex is banned in the United States, the supplement can be obtained in Mexico. The intent of this report was to describe the pattern of Redotex calls received by a statewide poison center system. Cases were all Redotex calls received by Texas poison centers during 2000-2008. The distribution of total calls and those involving ingestion of the supplement were determined for selected demographic and clinical factors. Of 34 total Redotex calls received, 55.9% came from the 14 Texas counties that border Mexico. Of the 22 reported Redotex ingestions, 77.3% of the patients were female and 45.5% 20 years or more. Of the 17 ingestions involving no co-ingestants, 52.9% were already at or en route to a health care facility, 41.2% were managed on site, and 5.9% was referred to a health care facility. The final medical outcome was no effect in 23.5% cases, minor effect in 5.9%, moderate effect in 11.8%, not followed but minimal clinical effects possible in 47.1%, and unable to follow but judged to be potentially toxic in 11.8%. Most Redotex calls to the Texas poison center system originated from counties bordering Mexico.

    2012-12-01

    Maternal mortality is often used to measure health and well-being for women. Improved surveillance efforts can improve maternal mortality estimates and inform the development of strategies to address the needs of maternal and child health populations. The purpose of this study was to provide better estimates of maternal mortality in Texas by using enhanced surveillance methods. Results from our analyses of fetal death and live birth records in Texas from 2000 through 2006 were then linked to pregnancy-related death records and death records of women of childbearing age (15-44 years) in Texas from 2001 through 2006. Enhanced surveillance identified almost 3.5 times as many deaths that might be associated with pregnancy than do current methods and confirmed a persistent race/ethnicity trend in maternal mortality. The leading cause of these 2001-2006 pregnancy-associated deaths was accidents. Enhanced surveillance allows the identification of additional deaths possibly associated with pregnancy and provides a stable foundation to investigate trends further and to review maternal mortality cases systematically.

    Bell, L.; Looke, B.

    2002-01-01

    The Texas Legislature is providing funding to support research and planning activities aimed at creating a commercial spaceport in the state. These monies have been allocated to regional Spaceport Development Corporations that have been established in three countries containing candidate site locations: Willacy County (in South Texas); Brazoria County (East Texas); and Pecos County (West Texas). This program is being sponsored and coordinated by the Texas Aerospace Commission (TAC). The Sasakawa International Center for Space Architecture (SICSA) at the University of Houston is providing research, planning and design support to TAC and is a member of each of the three regional development teams. Planning must carefully consider special support requirements and operational characteristics of all prospective launch systems along with geographic, infrastructure and environmental factors at each site. Two of the candidate sites are in coastal areas; a priority for certain launch service providers; whereas the third inland site is more attractive to others. Candidate launch systems include winged horizontal takeoff air-launch vehicles, vertical multi-stage reusable launch vehicles, and expendable sub-orbital surrounding rockets. Important research and planning activities include environmental impact assessments, analyses of overflight hazards, investigations of economic impacts and business plan development. The results of these activities will guide master plan development for each site, including: a physical plan (site layout, infrastructure improvements and facility construction); and a strategic plan (user agreements, licenses, finance sources and participants). Commercial spaceport development demands compliance with stringent FAA regulations established by the Office of Commercial Space Transportation (OCST) which exceed minimum standards allowed for U.S. Government spaceport facilities. Key among these requirements are 15,000 ft. radius on-site clear zones

  18. Texas Disasters II: Utilizing NASA Earth Observations to Assist the Texas Forest Service in Mapping and Analyzing Fuel Loads and Phenology in Texas Grasslands

    Science.gov (United States)

    Brooke, Michael; Williams, Meredith; Fenn, Teresa

    2016-01-01

    The risk of severe wildfires in Texas has been related to weather phenomena such as climate change and recent urban expansion into wild land areas. During recent years, Texas wild land areas have experienced sequences of wet and dry years that have contributed to increased wildfire risk and frequency. To prevent and contain wildfires, the Texas Forest Service (TFS) is tasked with evaluating and reducing potential fire risk to better manage and distribute resources. This task is made more difficult due to the vast and varied landscape of Texas. The TFS assesses fire risk by understanding vegetative fuel types and fuel loads. To better assist the TFS, NASA Earth observations, including Landsat and Moderate Resolution Imaging Specrtoradiometer (MODIS) data, were analyzed to produce maps of vegetation type and specific vegetation phenology as it related to potential wildfire fuel loads. Fuel maps from 2010-2011 and 2014-2015 fire seasons, created by the Texas Disasters I project, were used and provided alternating, complementary map indicators of wildfire risk in Texas. The TFS will utilize the end products and capabilities to evaluate and better understand wildfire risk across Texas.

    2002-12-01

    The value of groundwater has increased substantially worldwide due to expanding human consumption. Both the quantity and quality of groundwater are important considerations when constructing policies on natural resource conservation. This study is focused on evaluating groundwater quality in the state of Texas. Historical data from the Texas Water Development Board and the National Uranium Resource Evaluation were collected into a GIS database for spatial and temporal analyses. Specific attentions were placed on arsenic and other trace metals in groundwater. Recent studies in the United States have focused on isolated incidences of high arsenic occurrence, ignoring possible connections between arsenic and other trace metals. Descriptive statistics revealed strong correlations in groundwater between arsenic and other oxyanions including vanadium, selenium and molybdenum. Arsenic and associated trace metals were clustered at three physiographic hotspots, the Southern High Plains, the Gulf Coastal Plains of Texas, and West Texas. A geologic survey showed that arsenic and other trace metals in Texas groundwater follow local geologic trends. Uranium deposits and associated mineralization were found to occur in the same physiographic locations. Uranium mineralization may be a significant natural source of arsenic and other trace metals in Texas groundwater. Recharge, evaporative concentration, and aquifer characteristics were also contributing factors to the occurrence of trace metals in Texas groundwater. Spatial statistics were used to delineate natural sources from anthropogenic inputs. Similarly, the natural background was estimated from the spatial distribution of trace metal observations in Texas groundwater.

    Kratom use is a growing problem in the United States. Kratom exposures reported to Texas poison centers between January 1998 and September 2013 were identified. No kratom exposures were reported from 1998 to 2008 and 14 exposures were reported from 2009 to September 2013. Eleven patients were male, and 11 patients were in their 20s. The kratom was ingested in 12 patients, inhaled in 1, and both ingested and inhaled in 1. Twelve patients were managed at a healthcare facility and the remaining 2 were managed at home.

  16. Suspended sediment yield in Texas watersheds

    Coonrod, Julia Ellen Allred

    The Texas Water Development Board collected suspended sediment samples across the state of Texas for approximately 60 years. Until this research, no comprehensive analysis of the data had been conducted. This study compiles the suspended sediment data along with corresponding streamflow and rainfall. GIS programs are developed which characterize watersheds corresponding to the sediment gauging stations. The watersheds are characterized according to topography, climate, soils, and land use. All of the data is combined to form several SAS data sets which can subsequently be analyzed using regression. Annual data for all of the stations across the state are classified temporally and spatially to determine trends in the sediment yield. In general, the suspended sediment load increases with increasing runoff but no correlation exists with rainfall. However, the annual average rainfall can be used to classify the watersheds according to climate, which improves the correlation between sediment load and runoff. The watersheds with no dams have higher sediment loads than watersheds with dams. Dams in the drier parts of Texas reduce the sediment load more than dams in the wetter part of the state. Sediment rating curves are developed separately for each basin in Texas. All but one of the curves fall into a band which varies by about two orders of magnitude. The study analyzes daily time series data for the Lavaca River near Edna station. USGS data are used to improve the sediment rating curve by the addition of physically related variables and interaction terms. The model can explain an additional 41% of the variability in sediment concentration compared to a simple bivariate regression of sediment load and flow. The TWDB daily data for the Lavaca River near Edna station are used to quantify temporal trends. There is a high correlation between sediment load and flowrate for the Lavaca River. The correlation can be improved by considering a flow-squared term and by

    A beachrock correlative with the Ingleside complex of the late Pleistocene Beaumont Formation crops out discontinuously along the mainland shore of Laguna Madre, extending approximately 10 km southward from Baffin Bay, Texas. Carbon-14 dating yields ages of 23, 430 to 33,390 yrs. B.P.; the beachrock formed along a Gulf shoreline in a zone of converging longshore currents during the last sea level highstand of the late Wisconsinan. The beachrock shows intense karstification. Vertical, steep-walled solution pipes penetrate the outcrops, and reddish-brown laminated caliche crusts coat outcrop surfaces and solution-pipe walls in many places. These karst features probably formed by subaerial exposure and weathering of the beachrock during the latest sea level lowstand. Today in semiarid South Texas, rainfall averages only 28 inches per year. Local features of late Pleistocene age include river gravels coarser than modern loads of those same rivers, and relict drainage networks far denser than modern ones. Such features indicate that during the late Pleistocene this region was more humid than now. Karst is typical of humid to subhumid climates, also suggesting that during karstification of the beachrock wetter climates prevailed.

  1. An updated understanding of Texas bumble bee (Hymenoptera: Apidae) species presence and potential distributions in Texas, USA

    2017-01-01

    Texas is the second largest state in the United States of America, and the largest state in the contiguous USA at nearly 700,000 sq. km. Several Texas bumble bee species have shown evidence of declines in portions of their continental ranges, and conservation initiatives targeting these species will be most effective if species distributions are well established. To date, statewide bumble bee distributions for Texas have been inferred primarily from specimen records housed in natural history collections. To improve upon these maps, and help inform conservation decisions, this research aimed to (1) update existing Texas bumble bee presence databases to include recent (2007–2016) data from citizen science repositories and targeted field studies, (2) model statewide species distributions of the most common bumble bee species in Texas using MaxEnt, and (3) identify conservation target areas for the state that are most likely to contain habitat suitable for multiple declining species. The resulting Texas bumble bee database is comprised of 3,580 records, to include previously compiled museum records dating from 1897, recent field survey data, and vetted records from citizen science repositories. These data yielded an updated state species list that includes 11 species, as well as species distribution models (SDMs) for the most common Texas bumble bee species, including two that have shown evidence of range-wide declines: B. fraternus (Smith, 1854) and B. pensylvanicus (DeGeer, 1773). Based on analyses of these models, we have identified conservation priority areas within the Texas Cross Timbers, Texas Blackland Prairies, and East Central Texas Plains ecoregions where suitable habitat for both B. fraternus and B. pensylvanicus are highly likely to co-occur.

  3. Hispanic AIDS education in South Texas.

    Sanchez, J

    1988-04-01

    The Hispanic AIDS Committee for Education and Resources (HACER) was established in 1987 as an AIDS education program targeted at the Mexicano population of South Texas. The word "Mexicano" is used because "Hispanic" refers to a larger, more diversified group. "Mexicano" refers specifically to people of South Texas who are either Mexican-Americans (people of Mexican descent, born and educated in the US) or Mexicans (people born and educated in Mexico). Mexicanos constitute 56% of the population of South Texas and 54% of the population of San Antonio. Mexican-Americans, in general, speak and read English and listen to English-language television and radio. Mexicans are poorer and less educated, Spanish-speaking, and often illiterate. The Mexicanos do not constitute a high risk group for AIDS; at present there are only 64 Mexicano AIDS patients in San Antonio. AIDS education campaigns on television which are directed at the whole Hispanic community may be counter-productive when directed at the Mexicano population because they know that AIDS is not yet a serious problem among them, and scare tactics only cause hysteria. AIDS education is essential, but it must be specifically geared to the Mexicano community, which, in general, is a very conservative community, in which subjects like sex, homosexuality, condoms, or anal intercourse are not discussed in public. But it is also a community of young (median age 23) sexually active people. An AIDS education program directed at them must use simple, elementary language in standard Mexican Spanish for the Mexicans and in English for the young Mexican-Americans. The single most effective way to reach the Mexicano population would be public service announcements aired on television during the time when the telenovelas (soap operas) are on. Not only are the telenovelas widely watched, but their actors are popular heros, who will be listened to by their audience. The use of radio for public service announcements would be useful

    The authors conducted air quality measurements of the criteria pollutants carbon monoxide, nitrogen oxides, and ozone together with meteorological measurements at a park site southeast of College Station, TX, during the 2006 Texas Air Quality Study II (TexAQS). Ozone, a primary focus of the measurements, was above 80 ppb during 3 days and above 75 ppb during additional 8 days in summer 2006, suggestive of possible violations of the ozone National Ambient Air Quality Standard (NAAQS) in this area. In concordance with other air quality measurements during the TexAQS II, elevated ozone mixing ratios coincided with northerly flows during days after cold front passages. Ozone background during these days was as high as 80 ppb, whereas southerly air flows generally provided for an ozone background lower than 40 ppb. Back trajectory analysis shows that local ozone mixing ratios can also be strongly affected by the Houston urban pollution plume, leading to late afternoon ozone increases of as high as 50 ppb above background under favorable transport conditions. The trajectory analysis also shows that ozone background increases steadily the longer a southern air mass resides over Texas after entering from the Gulf of Mexico. In light of these and other TexAQS findings, it appears that ozone air quality is affected throughout east Texas by both long-range and regional ozone transport, and that improvements therefore will require at least a regionally oriented instead of the current locally oriented ozone precursor reduction policies.

    The performance of Texas high school students on mathematics exams is tightly connected to the level of poverty in the school. I will employ the coarse-graining techniques that lead from molecular motions to fluid mechanics in order to find how student scores evolve over time. I will show that the points of divergence between well-off and low-income kids are particularly clear when viewed as streamlines of a flow in the space of grade-level and score. The results can also be cast in the form of a Fokker-Planck equation, which highlights the separate roles of convection and diffusion. I will use the results the assess the plausibility of using charter schools, highly qualified teachers, and accountability systems as primary agents of school reform.

    We analyze the turbulence driven particle transport in Texas Helimak (K. W. Gentle and Huang He, Plasma Sci. and Technology, 10, 284 (2008)), a toroidal plasma device with one-dimensional equilibrium with magnetic curvature and shear. Alterations on the radial electric field, through an external voltage bias, change spectral plasma characteristics inducing a dominant frequency for negative bias values and a broad band frequency spectrum for positive bias values. For negative biased plasma discharges, the transport is high where the waves propagate with phase velocities near the plasma flow velocity, an indication that the transport is strongly affected by a wave particle resonant interaction. On the other hand, for positive bias the plasma has a reversed shear flow and we observe that the transport is almost zero in the shearless radial region, an evidence of a transport barrier in this region.

Fort Hood receives many solicitations from renewable energy vendors who are interested in doing projects on site. Based on specific requests from Fort Hood staff so they can better understand these proposals, and the results of PNNL's 2008 RE assessment of Fort Hood, the following resources were examined in this assessment: (1) Municipal solid waste (MSW) for waste-to-energy (WTE); (2) Wind; (3) Landfill gas; (4) Solar photovoltaics (PV); and (5) Shale gas. This report also examines the regulatory issues, development options, and environmental impacts for the promising RE resources, and includes a review of the RE market in Texas.

  10. The Texas Advanced Directive Law: Unfinished Business.

    Kapottos, Michael; Youngner, Stuart

    2015-01-01

    The Texas Advance Directive Act allows physicians and hospitals to overrule patient or family requests for futile care. Purposefully not defining futility, the law leaves its determination in specific cases to an institutional process. While the law has received several criticisms, it does seem to work constructively in the cases that come to the review process. We introduce a new criticism: While the law has been justified by an appeal to professional values such as avoiding harm to patients, avoiding the provision of unseemly care, and good stewardship of medical resources, it is applied incompletely. It allows physicians and institutional committees to refuse "futile" treatments desired by patients and families while at the same time providing no way of regulating physicians who recommend or even push "futile" treatments in similar cases. In this sense, the TADA is incomplete on its own terms.

    2006-06-01

    Methylphenidate is a stimulant used in the treatment of attention deficit hyperactivity disorder in children and is subject to abuse. This study describes the patterns of methylphenidate abuse and drug identification (ID) calls received by several poison control centers in Texas. Cases were calls involving methylphenidate received by Texas poison control centers during 1998-2004. Drug ID and drug abuse calls were assessed by call year and geographic location. Drug abuse calls were then compared to all other human exposure (nonabuse) calls with respect to various factors. Of 6798 calls received involving methylphenidate, 35% were drug IDs and 56% human exposures. Of the human exposures, 9% involved abuse. The number of drug ID calls and drug abuse calls received per year both declined during the first part of 7-yr period but then increased. Male patients accounted for approximately 60% of both drug abuse and nonabuse calls. Adolescent patients comprised 55% of drug abuse calls and children less than 13 yr old comprised 62% of nonabuse calls. Although the majority of both types of human exposures occurred at the patient's own residence, drug abuse calls were more likely than non-abuse calls to involve exposures at school (15% vs. 6%) and public areas (3% vs. 0.4%). While drug abuse calls were less likely than nonabuse calls to present with no clinical effects (29% vs. 52%), they were more likely to show more serious medical outcomes. Methylphenidate abusers are more likely to be adolescents. Methylphenidate abuse as compared to other exposures is more likely to occur outside of the person's home and to involve more serious medical outcomes.

  15. The Myth of the Texas Miracle in Education

    Directory of Open Access Journals (Sweden)

    Walt Haney

    2000-08-01

    Full Text Available I summarize the recent history of education reform and statewide testing in Texas, which led to introduction of the Texas Assessment of Academic Skills (TAAS in 1990-91. A variety of evidence in the late 1990s led a number of observers to conclude that the state of Texas had made near miraculous progress in reducing dropouts and increasing achievement. The passing scores on TAAS tests were arbitrary and discriminatory. Analyses comparing TAAS reading, writing and math scores with one another and with relevant high school grades raise doubts about the reliability and validity of TAAS scores. I discuss problems of missing students and other mirages in Texas enrollment statistics that profoundly affect both reported dropout statistics and test scores. Only 50% of minority students in Texas have been progressing from grade 9 to high school graduation since the initiation of the TAAS testing program. Since about 1982, the rates at which Black and Hispanic students are required to repeat grade 9 have climbed steadily, such that by the late 1990s, nearly 30% of Black and Hispanic students were "failing" grade 9. Cumulative rates of grade retention in Texas are almost twice as high for Black and Hispanic students as for White students. Some portion of the gains in grade 10 TAAS pass rates are illusory. The numbers of students taking the grade 10 tests who were classified as "in special education" and hence not counted in schools' accountability ratings nearly doubled between 1994 and 1998. A substantial portion of the apparent increases in TAAS pass rates in the 1990s are due to such exclusions. In the opinion of educators in Texas, schools are devoting a huge amount of time and energy preparing students specifically for TAAS, and emphasis on TAAS is hurting more than helping teaching and learning in Texas schools, particularly with at-risk students, and TAAS contributes to retention in grade and dropping out. Five different sources of evidence about

  16. State Agency Applications of EOS Data in Texas

    Science.gov (United States)

    Wells, G. L.

    2001-05-01

    Texas offers a good model for the introduction of remotely sensed data products into the daily operations of state agencies by virtue of its large size and population. The diversity of the Texas landscape coupled with the long distances traveled to perform site inspections place special burdens on the land resource agencies responsible for monitoring crop conditions, water availability, environmental hazards and other natural resource issues. To assist these agencies, the Texas Synergy team has adopted a two-phase approach that incorporates framework geospatial data products designed for the broad user community with remote sensing applications developed for user-specific analyses. A key element to the success of the effort is the development of remote sensing products within a Texas Reference Frame that corresponds to the components of the high-resolution National Spatial Data Infrastructure developed by the state, such as 1-meter CIR digital orthophotographs, digital elevation models, and vector layers for hypsography, hydrography, soils, transportation and boundaries. Users accustomed to working with NSDI products can easily begin to include recently-collected EOS data presented within the same reference frame. Examples of statewide data products made available through the Texas Synergy project are AVHRR NDVI and MODIS imagery, Landsat 7 ETM+ scenes and SPOT 10-meter panchromatic image tiles. Delivery of the products involves a number of mechanisms from CD distribution to Internet FTP downloads, but increasingly relies upon Internet map services, such as ESRI's ArcIMS. Beyond release of the base imagery products, the Texas Synergy team has worked with the Texas Parks and Wildlife Department, Texas Soil and Water Conservation Board, Texas Department of Agriculture, Texas Water Development Board, National Park Service and USDA Natural Resources Conservation Service on a wide range of data applications. Throughout 1999-2000, the magnitude of drought conditions was

    We identified 114 patients with neurocysticercosis admitted to Ben Taub General Hospital in Houston, Texas between January 1994 and June 1997. Most of these patients were born in Mexico (78%) or Central America (16%), but 6% were born in the United States. Review of neurology clinic records identified 54 patients diagnosed with neurocysticercosis, representing 2% of all neurology clinic patients and 16% of all Hispanics diagnosed with seizures. Forty-one patients were interviewed and all reported significant risk factors for infection, including ingestion of undercooked pork, pig husbandry, immigration from and frequent travel to villages in disease-endemic areas, or personal/family history of taeniasis. Among Mexican immigrants, most were born in rural areas in Central (31%) or north central Mexico (38%). Significantly fewer of the patients were from the border states (15%). The median period from immigration to diagnosis was 58 months, but it was 28 months for the 13 patients who had not left the United States after immigration. Although neurocysticercosis is being diagnosed with increasing frequency in the United States, acquisition of infection is still strongly associated with pig husbandry in rural Latin America, with little evidence of local transmission. Even among urban immigrants to the United States and United States-born cases, there is close ongoing contact with disease-endemic villages.

  18. Strong reinforcing selection in a Texas wildflower.

    Hopkins, Robin; Guerrero, Rafael F; Rausher, Mark D; Kirkpatrick, Mark

    2014-09-08

    Reinforcement, the process of increased reproductive isolation due to selection against hybrids, is an important mechanism by which natural selection contributes to speciation [1]. Empirical studies suggest that reinforcement has generated reproductive isolation in many taxa (reviewed in [2-4]), and theoretical work shows it can act under broad selective conditions [5-11]. However, the strength of selection driving reinforcement has never been measured in nature. Here, we quantify the strength of reinforcing selection in the Texas wildflower Phlox drummondii using a strategy that weds a population genetic model with field data. Reinforcement in this system is caused by variation in two loci that affect flower color [12]. We quantify sharp clines in flower color where this species comes into contact with its congener, Phlox cuspidata. We develop a spatially explicit population genetic model for these clines based on the known genetics of flower color. We fit our model to the data using likelihood, and we searched parameter space using Markov chain Monte Carlo methods. We find that selection on flower color genes generated by reinforcement is exceptionally strong. Our findings demonstrate that natural selection can play a decisive role in the evolution of reproductive isolation through the process of reinforcement.

    Households with incomes between 18% and 99% of the federal poverty level (FPL) are ineligible for Medicaid or enrollment in the health insurance exchange marketplace in Texas, resulting in the health insurance gap. We sought to determine the number of non-elderly adult Texans (NEATs) aged between 18 and 64 years in the insurance gap in rural vs urban areas in East Texas, West Texas, and South Texas. Data were obtained from the US Census Bureau website. In 2014, there were 1,101,000 NEATs in the insurance gap, accounting for 24.5% of all uninsured persons in Texas. The gap was significantly higher in rural vs urban areas in East and South Texas and in Texas as a whole. Large coverage gaps in states like Texas not expanding Medicaid under the Affordable Care Act pose major hurdles to reducing the number of uninsured individuals in these states.

    2013-01-01

    Mycoplasma agassizii causes upper respiratory tract disease (URTD) in Texas tortoises (Gopherus berlandieri). To determine exposure to and shedding of M. agassizii, we collected blood samples and nasal swabs from 40 free-ranging Texas tortoises on public and private lands in Texas, USA, from May to October 2009. We used an enzyme-linked immunosorbent assay (ELISA) to detect M. agassizii–specific antibodies. Eleven (28%) tortoises were antibody positive, three (8%) were suspect, and the remaining 26 (65%) were negative. Nasal lavage samples were collected from 35 of the 40 tortoises for M. agassizii culture and PCR to detect shedding of M. agassizii. Current infection with M. agassizii was confirmed in one tortoise that had mild clinical signs of URTD and was positive by ELISA (antibody titer >512), PCR, and culture. The clinical isolate was confirmed as M. agassizii by restriction fragment length polymorphism and immunobinding.

  10. Historical descriptions of some soils and landscapes of Texas

    Science.gov (United States)

    Schulze, Darrell G.

    Europeans explorers, immigrants, and travelers have been crisscrossing Texas for almost 5 centuries, recording their observations of soils and landscapes through the lens of their own times. In the early 16th century, Cabeza de Vaca was struck by how the natives among whom he lived used soil as a part of their diet. In the 17th century, as a member of the La Salle expedition to Texas, Henri Joutel described the soils and landscapes he saw in considerable detail, perhaps with an eye to possible future French settlement. To 19th century immigrants, the soil was the source of their future wealth, but also, so they thought, of the source of the various illnesses that inflicted them. With their distinctive micro-topography and large cracks when dry, Vertisols have elicited some of the most interesting early descriptions of Texas soils.

  11. Public perceptions and information gaps in solar energy in Texas

    Science.gov (United States)

    Rai, Varun; Beck, Ariane L.

    2015-07-01

    Studying the behavioral aspects of the individual decision-making process is important in identifying and addressing barriers in the adoption of residential solar photovoltaic (PV). However, there is little systematic research focusing on these aspects of residential PV in Texas, an important, large, populous state, with a range of challenges in the electricity sector including increasing demand, shrinking reserve margins, constrained water supply, and challenging emissions reduction targets under proposed federal regulations. This paper aims to address this gap through an empirical investigation of a new survey-based dataset collected in Texas on solar energy perceptions and behavior. The results of this analysis offer insights into the perceptions and motivations influencing intentions and behavior toward solar energy in a relatively untapped market and help identify information gaps that could be targeted to alleviate key barriers to adopting solar, thereby enabling significant emissions reductions in the residential sector in Texas.

    2013-04-01

    Northern Bobwhite (Colinus virginianus) and Scaled Quail (Callipepla squamata) occur throughout northwestern Texas and overall population numbers have been declining for the past 30 yr. This decline has been attributed to habitat loss associated with intensive agricultural practices. We propose that disease may be a contributing factor to decline. Our findings suggest that West Nile virus (WNV) infection may be common in wild quail populations on the Rolling Plains of northwestern Texas. Serum samples (n=301) from wild-caught Northern Bobwhite and Scaled Quail were collected during 2008-10 from seven private properties across the Rolling Plains Region; 5.3% had detectable antibodies against WNV using an enzyme-linked immunosorbent assay. To our knowledge, this is the first report of antibodies to WNV in Scaled Quail and wild-caught Northern Bobwhite from the Rolling Plains of Texas.

    2004-07-26

    The State Energy Conservation Office has executed its first Fuel Cell Project which was awarded under a Department of Energy competitive grant process. The Texas LPG Fuel Processor Development and Fuel Cell Demonstration Program is a broad-based public/private partnership led by the Texas State Energy Conservation Office (SECO). Partners include the Alternative Fuels Research and Education Division (AFRED) of the Railroad Commission of Texas; Plug Power, Inc., Latham, NY, UOP/HyRadix, Des Plaines, IL; Southwest Research Institute (SwRI), San Antonio, TX; the Texas Natural Resource Conservation Commission (TNRCC), and the Texas Department of Transportation (TxDOT). The team proposes to mount a development and demonstration program to field-test and evaluate markets for HyRadix's LPG fuel processor system integrated into Plug Power's residential-scale GenSys(TM) 5C (5 kW) PEM fuel cell system in a variety of building types and conditions of service. The program's primary goal is to develop, test, and install a prototype propane-fueled residential fuel cell power system supplied by Plug Power and HyRadix in Texas. The propane industry is currently funding development of an optimized propane fuel processor by project partner UOP/HyRadix through its national checkoff program, the Propane Education and Research Council (PERC). Following integration and independent verification of performance by Southwest Research Institute, Plug Power and HyRadix will produce a production-ready prototype unit for use in a field demonstration. The demonstration unit produced during this task will be delivered and installed at the Texas Department of Transportation's TransGuide headquarters in San Antonio, Texas. Simultaneously, the team will undertake a market study aimed at identifying and quantifying early-entry customers, technical and regulatory requirements, and other challenges and opportunities that need to be addressed in planning commercialization of the units

    Chagas disease is an important emerging disease in Texas that results in cardiomyopathy in about 30% of those infected with the parasite Trypanosoma cruzi. Between the years 2008 and 2012, about 1/6500 blood donors were T. cruzi antibody-confirmed positive. We found older persons and minority populations, particularly Hispanic, at highest risk for screening positive for T. cruzi antibodies during routine blood donation. Zip code analysis determined that T. cruzi is associated with poverty. Chagas disease has a significant disease burden and is a cause of substantial economic losses in Texas.

  7. Texas Hydrogen Education Final Scientific/Technical Report

    Energy Technology Data Exchange (ETDEWEB)

    Hitchcock, David; Bullock, Dan

    2011-06-30

    The Texas Hydrogen Education project builds on past interest in hydrogen and fuel cells to help create better informed leaders and stakeholders and thereby improve decision making and planning for inclusion of hydrogen and fuel cell technologies as energy alternatives in Texas. In past years in Texas, there was considerable interest and activities about hydrogen and fuel cells (2000-­2004). During that time, the Houston Advanced Research Center (HARC) created a fuel cell consortium and a fuel cell testing lab. Prior to 2008, interest and activities had declined substantially. In 2008, in cooperation with the Texas H2 Coalition and the State Energy Conservation Office, HARC conducted a planning process to create the Texas Hydrogen Roadmap. It was apparent from analysis conducted during the course of this process that while Texas has hydrogen and fuel cell advantages, there was little program and project activity as compared with other key states. Outreach and education through the provision of informational materials and organizing meetings was seen as an effective way of reaching decision makers in Texas. Previous hydrogen projects in Texas had identified the five major urban regions for program and project development. This geographic targeting approach was adopted for this project. The project successfully conducted the five proposed workshops in four of the target metropolitan areas: San Antonio, Houston, Austin, and the Dallas-­Ft. Worth area. In addition, eight outreach events were included to further inform state and local government leaders on the basics of hydrogen and fuel cell technologies. The project achieved its primary objectives of developing communication with target audiences and assembling credible and consistent outreach and education materials. The major lessons learned include: (1) DOE’s Clean Cities programs are a key conduit to target transportation audiences, (2) real-­world fuel cell applications (fuel cell buses, fuel cell fork lifts

    This document presents a case study of energy policies in Texas related to power system transformation, renewable energy and distributed energy resources (DERs). Texas has experienced a dramatic increase in installed wind capacity, from 116 MW in 2000 to over 15,000 MW in 2015. This achievement was enabled by the designation of Competitive Renewable Energy Zones (CREZs) and new transmission lines that transmit wind to load centers. This report highlights nascent efforts to include DERs in the ERCOT market. As costs decline and adoption rates increase, ERCOT expects distributed generation to have an increasing effect on grid operations, while bringing potentially valuable new resources to the wholesale markets.

  10. Using U-series Isotopes To Determine Sources Of Pedogenic Carbonates: Comparison Of Natural And Agricultural Soils In The Semi-arid Southern New Mexico And Western Texas

    Pedogenic carbonates commonly precipitate from infiltrating soil water in arid and semi-arid lands and are observed in soils of southern New Mexico and western Texas. These carbonates could form an impermeable layer in the soil horizons impairing water infiltration, thus affecting crop growth and yield. It is important to determine the source of C and Ca in these carbonates and to understand conditions favoring their formation, kinetics and precipitation rates. In this study, major elements and U-series isotopes in bulk calcic soils, and weak acid leachates and residues were measured from one irrigated alfalfa site in the Hueco basin near El Paso, TX and one natural shrubland site on the USDA Jornada experimental range in southern NM. The combined geochemical and isotopic results allow us to determine the formation ages of the carbonates; investigate the mobility of U, Th, and major elements in these soils; and infer for the effects of irrigation on carbonate formation in agricultural soils. Our results show distinctive U and Th isotope systems in the two soil profiles analyzed. For example, (234U/238U) ratios in the Jornada bulk soils decrease from ~1.01 to 0.96 towards the surface, consistent with a preferential loss of 234U over 238U during chemical weathering. At the Jornada site, (238U/232Th) ratios decrease while (230Th/238U) increase towards the surface, consistent with a general depletion of U and the immobility of Th in the natural soils. By contrast at the Alfalfa site, (234U/238U) ratios of bulk soils increase from ~ 0.97 to 1.02 towards the surface, suggesting an additional source of external uranium, most likely the irrigation water from Rio Grande which has a (234U/238U) ratio of ~ 1.5 near El Paso. The (238U/232Th) and (230Th/238U) ratios also imply leaching of U from shallower soils but precipitation in greater depths at Alfalfa site; suggests that partial dissolution and re-precipitation of younger carbonates occur. Calculated carbonate ages from U

    The Texas Water Development Board (TWDB), Texas Parks and Wildlife Department (TPWD), and Texas Natural Resource Conservation Commission (TNRCC) are charged by the Texas Legislature with determining freshwater inflows required to maintain the ecological health of streams, bays, and estuaries in Texas. To determine required inflows, the three agencies collect data and conduct studies on the needs for freshwater inflows to estuaries. The TWDB uses estuarine hydrodynamic and conservativetransport computer models to predict the effects of altering freshwater inflows on estuarine circulation and salinity. To calibrate these models, a variety of water-quality and discharge data are needed.

    The amount of greenness around mothers' residences has been associated with positive birth outcomes; however, findings are inconclusive. Here we examine residential greenness and birth outcomes in a population-based birth cohort in Texas, a state with large regional variation in greenness levels, several distinct cities, and a diverse population. We used Vital Statistics data to create a birth cohort (n=3,026,603) in Texas from 2000 to 2009. Greenness exposure measures were estimated from full residential addresses across nine months of pregnancy, and each trimester specifically, using the mean of corresponding MODIS satellite 16-day normalized difference vegetation index (NDVI) surfaces at a 250m resolution, which have not been previously used. Logistic and linear mixed models were used to determine associations with preterm birth, small for gestational age (SGA) and term birth weight, controlling for individual and neighborhood factors. Unadjusted results demonstrated consistent protective effects of residential greenness on adverse birth outcomes for all of Texas and the four largest cities (Houston, San Antonio, Dallas, and Austin). However, in fully adjusted models these effects almost completely disappeared. For example, mothers with the highest (>0.52) compared to the lowest (Texas and diverse populations, we did not observe consistent associations between residential greenness and birth outcomes.

    Modern techniques for characterizing tectonic stress orientation and relative magnitude have been successfully used for more than 35 years. Nevertheless, large areas of North America lack high spatial resolution maps of stress orientation, magnitude, and faulting regime. In Texas, for example, geothermal resources. This year, we launched the Texas Stress Map project to characterize tectonic stress patterns at higher spatial resolution across Texas and nearby areas. Following a successful effort just completed in Oklahoma, we will evaluate borehole breakouts, drilling-induced tensile fractures, shear wave anisotropy, and earthquake data. The principal data source will be FMI (fullbore formation microimager), UBI (ultrasonic borehole imager), cross-dipole sonic, density, and caliper logs provided by private industry. Earthquake moment tensor solutions from the U.S. Geological Survey, Saint Louis University and other sources will also be used. Our initial focus is on the Permian Basin and Barnett Shale petroleum plays due to the availability of data, but we will expand our analysis across the state as the project progresses. In addition, we hope to eventually apply the higher spatial resolution data coverage to understanding tectonic and geodynamic characteristics of the southwestern United States and northeastern Mexico. Here we present early results from our work to constrain stress orientations and faulting regime in and near Texas, and we also provide a roadmap for the ongoing research.

  5. Carbon monoxide exposures after hurricane Ike - Texas, September 2008.

    Science.gov (United States)

    2009-08-14

    During power outages after hurricanes, survivors can be at risk for carbon monoxide (CO) poisoning if they use portable generators improperly. On September 13, 2008, Hurricane Ike struck the coast of Texas, leaving approximately 2.3 million households in the southeastern portion of the state without electricity. Six days later, 1.3 million homes were still without electrical power. To assess the impact of storm-related CO exposures and to enhance prevention efforts, CDC analyzed data from five disparate surveillance sources on CO exposures reported during September 13--26 in counties of southeast Texas that were declared disaster areas by the federal government. This report describes the results of that analysis, which indicated that one data source, Texas poison centers, received reports of 54 persons with storm-related CO exposures during the surveillance period. Another data source, the Undersea and Hyperbaric Medical Society (UHMS) hyperbaric oxygen treatment database, reported that 15 persons received hyperbaric oxygen treatment for storm-related CO poisoning. Medical examiners, public health officials, and hospitals in Texas reported that seven persons died from storm-related CO poisoning. Among the data sources, the percentage of reported storm-related CO exposures caused by improper generator use ranged from 82% to 87%. These findings underscore the need for effective prevention messages during storm preparation, warnings, and response periods regarding the correct use of generators and the installation and maintenance of battery-powered CO detectors.

    2016-06-01

    Today, Lyme disease is the most commonly reported tick-borne disease in the United States and Europe. The culprits behind Lyme disease are the Borrelia species of bacteria. In the USA, Borrelia burgdorferi causes the majority of cases, while in Europe and Asia Borrelia afzelii and Borrelia garinii carry the greatest burden of disease. The clinical manifestations of Lyme disease have been identified as early localized, early disseminated, and late chronic. The neurological effects of Lyme disease include both peripheral and central nervous systems involvement, including focal nerve abnormalities, cranial neuropathies, painful radiculoneuritis, meningitis, and/or toxic metabolic encephalopathy, known as Lyme encephalopathy. Given the geographic predominance of Lyme disease in the Northeast and Midwest of the USA, no major studies have been conducted regarding Southern states. Between 2005 and 2014, the Center for Disease Control has reported 582 confirmed cases of Lyme disease in Texas. Because of the potential for increased incidence and prevalence in Texas, it has become essential for research and clinical efforts to be diverted to the region. The Texas A&M College of Veterinary Medicine and Biomedical Sciences Lyme Lab has been investigating the ecology of Lyme disease in Texas and developing a pan-specific serological test for Lyme diagnosis. This report aimed to exposure materials and raise awareness of Lyme disease to healthcare providers.

  4. Panola NGL (natural gas liquid) line laid in east Texas

    Energy Technology Data Exchange (ETDEWEB)

    1982-11-01

    Construction is complete on the Panola Products Pipeline Co. 8-in. NGL line in E. Texas. The 60-mile pipeline, which traverses rolling timber country, lightly developed commercial areas, and low-lying wetlands, will ultimately gather liquids from gas plants in E. Texas. Initially, this system is designed to transport natural gas liquids mix from the Carthage Plant, operated by Champlin Petroleum Co., to Gulf Pipeline Co.'s injection station at Lufkin, Texas. Final delivery will be made to various petrochemical facilities in the Mont Belvieu, Texas area. To minimize right-of-way problems, the line was routed parallel to an existing United Gas 22-in. pipeline for a distance of 36 miles from Carthage to near Nacogdoches. The pipeline has a design pressure of 1,480 psi. A back pressure of approx. 450 psi will be maintained on the line at all times to keep the mix in a liquid state. The predominant pipe used along the route is API 5LX-52 with a wall thickness of 0.219-in. Heavier wall thickness pipe, up to 0.375-in., is used for road, railroad, and major water crossings.

  9. Wildlife Contact Rates at Artificial Feeding Sites in Texas

    Science.gov (United States)

    Campbell, Tyler A.; Long, David B.; Shriner, Susan A.

    2013-06-01

    Given the popularity of feeding white-tailed deer ( Odocoileus virginianus) in Texas and the increasing amount of corn that is distributed, more information is needed on the impacts of this activity on non-target wildlife. Our objectives were to report visitation, intra- and interspecific contact, and contact rates of wildlife at artificial feeding sites in Texas. Our study was conducted at three sites in Kleberg and Nueces counties, Texas. We trapped animals from February to April and August to September, 2009 and marked animals with passive integrated transponder (PIT) tags. At each site and season, we placed one feeder system containing a PIT tag reader within 600 m of trap locations. Readers detected PIT tags from a distance of 25 cm. We determined a contact event to occur when two different PIT tags were detected by feeder systems within 5 s. We recorded 62,719 passes by raccoons ( Procyon lotor), 103,512 passes by collared peccaries ( Pecari tajacu), 2,923 passes by feral swine ( Sus scrofa), 1,336 passes by fox squirrels ( Sciurus niger), and no passes by opossums ( Didelphis virginiana) at feeder systems. For site-season combinations in which contact events occurred, we found intraspecific contact rates (contacts per day) for raccoons, collared peccaries, and feral swine to be 0.81-124.77, 0.69-38.08, and 0.0-0.66, respectively. Throughout our study we distributed ~2,625 kg of whole kernel corn, which resulted in 6,351 contact events between marked wildlife (2.4 contacts per kg of corn). If 136 million kg of corn is distributed in Texas annually, we would expect >5.2 billion unnatural contact events between wildlife would result from this activity each year in Texas. Consequently, we do not believe that it is wise for natural resource managers to maintain artificial feeding sites for white-tailed deer or other wildlife due to pathogen transmission risks.

    This image of Houston, Texas, shows the amount of detail that is possible to obtain using spaceborne radar imaging. Images such as this -- obtained by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) flying aboard the space shuttle Endeavor last fall -- can become an effective tool for urban planners who map and monitor land use patterns in urban, agricultural and wetland areas. Central Houston appears pink and white in the upper portion of the image, outlined and crisscrossed by freeways. The image was obtained on October 10, 1994, during the space shuttle's 167th orbit. The area shown is 100 kilometers by 60 kilometers (62 miles by 38 miles) and is centered at 29.38 degrees north latitude, 95.1 degrees west longitude. North is toward the upper left. The pink areas designate urban development while the green-and blue-patterned areas are agricultural fields. Black areas are bodies of water, including Galveston Bay along the right edge and the Gulf of Mexico at the bottom of the image. Interstate 45 runs from top to bottom through the image. The narrow island at the bottom of the image is Galveston Island, with the city of Galveston at its northeast (right) end. The dark cross in the upper center of the image is Hobby Airport. Ellington Air Force Base is visible below Hobby on the other side of Interstate 45. Clear Lake is the dark body of water in the middle right of the image. The green square just north of Clear Lake is Johnson Space Center, home of Mission Control and the astronaut training facilities. The black rectangle with a white center that appears to the left of the city center is the Houston Astrodome. The colors in this image were obtained using the follow radar channels: red represents the L-band (horizontally transmitted, vertically received); green represents the C-band (horizontally transmitted, vertically received); blue represents the C-band (horizontally transmitted and received).

    2012-01-01

    We examined the prevalence of actions taken to control blood pressure as measured by taking antihypertensive medication or making lifestyle modifications among hypertensive adults residing along the Texas/Mexico border. We used self-reported data from the 2007 Texas Behavioral Risk Factor Surveillance System, with oversampling of border counties. We calculated the age-standardized prevalence of actions taken to control hypertension by selected characteristics. In analyses that combined ethnicity with predominant language spoken, those least likely to take any action to control their blood pressure--either by taking an antihypertensive medication or by making any of four lifestyle modifications--were Spanish-speaking Hispanic people (83.2% ± 2.7% standard error [SE]), with English-speaking non-Hispanic people (88.9% ± 0.8% SE) having the highest prevalence of taking action to control blood pressure. When analyzed by type of medical category, uninsured Hispanic people (63.8% ± 4.8% SE) had the lowest prevalence of taking action to control their blood pressure compared with uninsured non-Hispanic people (75.4% ± 4.7% SE). Nonborder Texas residents with hypertension were more likely to take antihypertensive medications (78.4% ± 1.0% SE) than border county residents with hypertension (70.7% ± 2.0% SE). Public health efforts must be undertaken to improve the control of hypertension among residents of Texas counties along the Mexico border, particularly for uninsured Hispanic people.

    2011-10-01

    For more than 40 years the Texas Institute of Behavioral Research (IBR) has given special attention to assessment and evaluation of drug user populations, addiction treatment services and various cognitive and behavioral interventions. Emphasis has been on studies in real-world settings and the use of multivariate methodologies to address evaluation issues within the context of longitudinal natural designs. Historically, its program of addiction treatment research may be divided into three sequential epochs-the first era dealt mainly with client assessment and its role in treatment outcome and evaluation (1969-89), the second focused upon modeling the treatment process and the importance of conceptual frameworks (1989-2009) in explaining the relationships among treatment environment, client attributes, treatment process and outcome, and the third (and current) era has expanded into studying tactical deployment of innovations and implementation. Recent projects focus upon adapting and implementing innovations for improving early engagement in adolescent residential treatment settings and drug-dependent criminal justice populations. Related issues include the spread of human immunodeficiency virus/acquired immune deficiency syndrome and other infectious diseases, organizational and systems functioning, treatment costs and process related to implementation of evidence-based practices.

  18. Disbursement of $65 million to the State of Texas for construction of a Regional Medical Technology Center at the former Superconducting Super Collider Site, Waxahachie, Texas

    Energy Technology Data Exchange (ETDEWEB)

    1995-05-01

    As part of a settlement agreement between the US DOE and the State of Texas, DOE proposes to transfer $65 million of federal funds to the Texas National Research Laboratory Commission (TNLRC) for construction of the Regional Medical Technology Center (RMTC) to be located in Ellis County, Texas. The RMTC would be a state-of-the-art medical facility for proton cancer therapy, operated by the State of Texas in conjunction with the University of Texas Southwestern Medical Center. The RMTC would use the linear accelerator assets of the recently terminated DOE Superconducting Super Collider Project to accelerate protons to high energies for the treatment of cancer patients. The current design provides for treatment areas, examination rooms, support laboratories, diagnostic imaging equipment, and office space as well as the accelerators (linac and synchrotron) and beam steering and shaping components. The potential environmental consequences of the proposed action are expected to be minor.

    2008-12-01

    OBJECTIVE: To examine how knowledge about the Texas top 10% law influences college enrollment decisions of high achieving students minority and nonminority students. DATA AND METHODS: Using a representative survey of graduates from Texas public high schools in 2002, we compare self-reported and transcript-verified class rank and estimate probit models to assess the likelihood that top-ranked minority students know about the law. RESULTS: Family socioeconomic status largely explains why highly ranked black and Hispanic students know less about the top 10% law than comparable whites, but parents' lack of fluency in English is a significant information barrier for college-bound, top 10% Hispanic students from predominantly minority high schools. Nearly one-fifth of college-oriented black and Hispanic top 10% seniors who did not know about the law failed to enroll anywhere. CONCLUSION: Inadequate information about the top 10% law undermines enrollment of talented minorities in higher education.

    2017-03-15

    A numerical study of connectivity between the continental shelf and coast in the northwestern Gulf of Mexico using a circulation model and surface-limited numerical drifters shows that despite seasonal changes in winds, the overall connectivity of the shelf with the coastline is similar in the winter and summer, though it extends more offshore in Texas in summer. However, there is a spatial pattern to the connectivity: more of the inner shelf is connected with the coast in Texas as compared with Louisiana. Subsets of the coast do have seasonal variability: the coast near both Galveston and Port Aransas has more connectivity from upcoast in the winter and from offshore and downcoast in the summer. In both seasons, we find drifters reach the Port Aransas coast most frequently, with a stronger trend in the summer. These results are important for assessing likely pathways for spilled oil and other potentially hazardous material. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In addition to the Affordable Care Act, states are more frequently turning to Medicaid waivers to achieve the "Triple Aim" goals of improving the experience of care, improving population health, and reducing per capita costs. These demonstration waivers provide opportunities to test innovative ways to finance and deliver care. Texas is currently implementing a waiver known as the Transformation and Quality Improvement Program. Its inclusion of public health agencies is a unique approach to a system typically limited to traditional providers. San Antonio Metropolitan Health District is one public health agency taking advantage of this new funding opportunity to implement 6 new or expanded programs targeting health issues of highest priority in this south Texas region. This article discusses the use of Medicaid waivers and the advantages and challenges of public health agency participation.

    Stephen E. Lile

    2000-01-01

    Full Text Available This paper examines the changing market shares of major Texas religious groups during this century. Market shares are computed by dividing membership by Texas population. Results show that certain religious groups (firms have performed much better in terms of market share than others. The better performers are the more conservative Protestant denominations along with the Roman Catholic Church. Groups losing market share tendto be the more liberal Protestant denominations. This finding would appear to be consistent with Niebuhr’s church-sect theory which, among other things, predicts that religious groups (sects characterized by a high degree of tension with society grow whereas groups (churches characterized by alow degree of tension with society tend to decline.

  6. Are Increasing Test Scores in Texas Really a Myth?

    2002-03-01

    Full Text Available Pass rates by Texas tenth-graders on the high school exit exam improved from 52 percent in 1994 to 72 percent in 1998. In his article "The Myth of the Texas Miracle in Education" (EPAA, August 2000 Professor Walt Haney argued that some part of this increased pass rate was, as he put it, an illusion. Haney contended that the combined effects of students dropping out of school prior to taking the 10th grade TAAS and special education exemptions accounted for much of the increase in TAAS pass rates. Relying on the same methodology and data that Haney used, we demonstrate that his conclusion is incorrect. None of the 20 percent improvement in the TAAS exit test pass rate between 1994 and 1998 is explained by combined increases in dropout rates or special education exemptions.

    Floods are natural hazards that can have damaging impacts not only on affected land areas but also on the adjacent coastal waters. NASA's Soil Moisture Active Passive (SMAP) mission provides measurements of both surface soil moisture and sea surface salinity (SSS), offering the opportunity to study the effects of flooding events on both terrestrial and marine environments. Here, we present analysis of a severe flood that occurred in May 2015 in Texas using SMAP observations and ancillary satellite and in situ data that describe the precipitation intensity, the evolving saturation state of the land surface, the flood discharge peak, and the resulting freshwater plume in the Gulf of Mexico. We describe the spatiotemporal evolution of the different variables, their relationships, and the associated physical processes. Specifically, we identify a freshwater plume in the north-central Gulf, being distinct from the typical Mississippi River plume, that is attributable to the Texas flood.

    2014-01-01

    Pollen from members of the Cupressaceae are major aeroallergens in many parts of the world. In the south central and southwest United States, Juniperus pollen is the most important member of this family with J. ashei (JA) responsible for severe winter allergy symptoms in Texas and Oklahoma. In New Mexico, pollen from J. monosperma (JM) and other Juniperus species are important contributors to spring allergies, while J. pinchotii (JP) pollinates in the fall affecting sensitive individuals in west Texas, southwest Oklahoma and eastern New Mexico. Throughout this region, JA, JM, and JP occur in dense woodland populations. Generally monitoring for airborne allergens is conducted in urban areas, although the source for tree pollen may be forested areas distant from the sampling sites. Improved pollen forecasts require a better understanding of pollen production at the source. The current study was undertaken to examine the aerobiology of several Juniperus species at their source areas for the development of new pollen forecasting initiatives.

  9. Pricing and University Autonomy: Tuition Deregulation in Texas

    Directory of Open Access Journals (Sweden)

    Jeongeun Kim

    2016-04-01

    Full Text Available This paper investigates changes in tuition policies in the wake of tuition deregulation in Texas, which in 2003 transferred tuition-setting authority from the state legislature to institutions. We find that price increases accelerated, particularly at the most selective institutions. Institutions also began differentiating price by undergraduate program, raising relative prices for the most costly and lucrative majors, including engineering, business, nursing, and architecture. Price increases were particularly large for institutions with the highest initial costs and for programs with a high earnings premium within institutions, though lower for institutions with more low-income students. These distinctions suggest that public postsecondary institutions respond to microeconomic incentives when given greater autonomy to set price, and take some measures to alleviate impacts on low-income students. The Texas experience suggests that decentralized price-setting generates greater price differentiation within the public higher education system, both across and within institutions.

    Furrow diking can prevent irrigation and rainfall runoff, conserve energy use, prevent soil loss, amd allow producers to reclaim land otherwise unusable, depending on soil, climate, and crops grown in a given area. Initial investment to use this technique may be recovered within the first season. This study analyzes the effects of diking on water and soil conservation, crop yields, costs, and energy use in farming, using examples of farms in the Texas High Plains area.

  13. What Do Test Scores in Texas Tell Us?

    Directory of Open Access Journals (Sweden)

    Stephen P. Klein et al

    2000-10-01

    Full Text Available We examine the results on the Texas Assessment of Academic Skills (TAAS, the highest-profile state testing program and one that has recorded extraordinary recent gains in math and reading scores. To investigate whether the dramatic math and reading gains on the TAAS represent actual academic progress, we have compared these gains to score changes in Texas on another test, the National Assessment of Educational Progress (NAEP. Texas students did improve significantly more on a fourth-grade NAEP math test than their counterparts nationally. But, the size of this gain was smaller than their gains on TAAS and was not present on the eighth-grade math test. The stark differences between the stories told by NAEP and TAAS are especially striking when it comes to the gap in average scores between whites and students of color. According to the NAEP results, that gap in Texas is not only very large but increasing slightly. According to TAAS scores, the gap is much smaller and decreasing greatly. Many schools are devoting a great deal of class time to highly specific TAAS preparation. While this preparation may improve TAAS scores, it may not help students develop necessary reading and math skills. Schools with relatively large percentages of minority and poor students may be doing this more than other schools. We raise serious questions about the validity of those gains, and caution against the danger of making decisions to sanction or reward students, teachers and schools on the basis of test scores that may be inflated or misleading. Finally, we suggest some steps that states can take to increase the likelihood that their test results merit public confidence and provide a sound basis for educational policy.

  14. The Texas A&M Radioisotope Production and Radiochemistry Program

    2016-08-31

    The main motivation of the project at Texas A&M University was to carry out the production of critically needed radioisotopes used in medicine for diagnostic and therapy, and to establish an academic program in radionuclide production and separation methods. After a lengthy battle with the Texas A&M University Radiation Safety Office, the Texas Department of State Health Services granted us a license for the production of radionuclides in July 2015, allowing us to work in earnest in our project objectives. Experiments began immediately after licensing, and we started the assembly and testing of our target systems. There were four analytical/theoretical projects and two experimental target systems. These were for At-211 production and for Zn- 62/Cu-62 production. The theoretical projects were related to the production of Mo-99/Tc-99m using (a) a subcritical aqueous target system and (b) production of Tc-99m from accelerator-generated Mo-99 utilizing a photon-neutron interaction with enriched Mo-100 targets. The two experimental projects were the development of targetry systems and production of At-211 and Zn-62/Cu-62 generator. The targetry system for At-211 has been tested and production of At-211 is chronic depending of availability of beam time at the cyclotron. The installation and testing of the targetry system for the production of Zn-62/Cu-62 has not been finalized. A description of the systems is described. The academic program in radionuclide production and separation methods was initiated in the fall of 2011; due to the lack of a radiochemistry laboratory, it was suspended. We expect to re-start the academic program at the Texas A&M Institute for Preclinical Studies under the Molecular Imaging Program.

    The main motivation of the project at Texas A&M University was to carry out the production of critically needed radioisotopes used in medicine for diagnostics and therapy, and to establish an academic program in radionuclide production and separation methods. After a lengthy battle with the Texas A&M University Radiation Safety Office, the Texas Department of State Health Services granted us a license for the production of radionuclides in July 2015, allowing us to work in earnest in our project objectives. Experiments began immediately after licensing, and we started the assembly and testing of our target systems. There were four analytical/theoretical projects and two experimental target systems. These were for At-211 production and for Zn-62/Cu-62 production. The theoretical projects were related to the production of Mo-99/Tc-99m using a) a subcritical aqueous target system and b) production of Tc-99m from accelerator generated Mo-99 utilizing a photon-neutron interaction with enriched Mo-100 targets. The two experimental projects were the development of targetry systems and production of At-211 and Zn-62/Cu-62 generator. The targetry system for At-211 has been tested and production of At-211 is chronic depending of availability of beam time at the cyclotron. The installation and testing of the targetry system for the production of Zn-62/Cu-62 has not been finalized. A description of the systems is described. The academic program in radionuclide production and separation methods was initiated in the fall of 2011 and due to the lack of a radiochemistry laboratory it was suspended. We expect to re-start the academic program at the Texas A&M Institute for Preclinical Studies under the Molecular Imaging Program.

    Full Text Available Disseminated histoplasmosis affecting the adrenal gland(s of immunocompetent adults is a very rare infection. Here, we present a case of bilateral adrenal histoplasmosis in an immunocompetent, 62-year-old gentleman from Texas along with a brief review of the published literature. Given the risk of patient decompensation secondary to adrenal insufficiency and the wide availability of effective treatments, adrenal histoplasmosis must be considered even in immunocompetent adults who acquire adrenal masses.

  1. Geothermal and heavy-oil resources in Texas

    In a five-county area of South Texas, geopressured-geothermal reservoirs in the Paleocene-Eocene Wilcox Group lie below medium- to heavy-oil reservoirs in the Eocene Jackson Group. This fortuitous association suggests the use of geothermal fluids for thermally enhanced oil recovery (TEOR). Geothermal fairways are formed where thick deltaic sandstones are compartmentalized by growth faults. Wilcox geothermal reservoirs in South Texas are present at depths of 11,000 to 15,000 ft (3,350 to 4,570 m) in laterally continuous sandstones 100 to 200 ft (30 to 60 m) thick. Permeability is generally low (typically 1 md), porosity ranges from 12 to 24 percent, and temperature exceeds 250{degrees}F (121{degrees}C). Reservoirs containing medium (20{degrees} to 25{degrees} API gravity) to heavy (10{degrees} to 20{degrees} API gravity) oil are concentrated along the Texas Coastal Plain in the Jackson-Yegua Barrier/Strandplain (Mirando Trend), Cap Rock, and Piercement Salt Dome plays and in the East Texas Basin in Woodbine Fluvial/Deltaic Strandplain and Paluxy Fault Line plays. Injection of hot, moderately fresh to saline brines will improve oil recovery by lowering viscosity and decreasing residual oil saturation. Smectite clay matrix could swell and clog pore throats if injected waters have low salinity. The high temperature of injected fluids will collapse some of the interlayer clays, thus increasing porosity and permeability. Reservoir heterogeneity resulting from facies variation and diagenesis must be considered when siting production and injection wells within the heavy-oil reservoir. The ability of abandoned gas wells to produce sufficient volumes of hot water over the long term will also affect the economics of TEOR.

    Cultural competence [CC] is an essential component of nursing education and nursing practice yet there is a gap in the research evaluating CC in faculty and how to practically develop this skillset for faculty members. To explore CC in faculty as evaluated with the Nurses' Cultural Competence Scale [NCCS] and apply the findings to the Purnell Model of Cultural Competence [PMCC] to guide professional development opportunities for faculty members. This was a concurrent mixed-methods study. Faculty members teaching in Texas nursing programs were recruited for the study. Quantitative data was collected using an online survey tool and qualitative data was collected over the phone. 89 Texas faculty members completed the quantitative strand and a subset of 10 faculty members completed the qualitative strand. Descriptive statistics were used to examine the quantitative data and Strauss and Corbin's methodology guided the evaluation of the qualitative data. These two strands were used to support the results. Faculty in Texas are moderately culturally competent. The qualitative findings support the application of the PMCC to the areas identified by the NCCS. The PMCC may be applied to the application of culture and values in nursing professional education as supported by the NCCS. Recommendations are to include the PMCC as a structure for the creation of professional development opportunities for faculty. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The media has given much attention to the academic cheating crisis in America. A majority of college students believe that, in today's global environment, it is necessary to cheat in order to get ahead and to compete with their peers. The prevalence and attitudes concerning academic dishonesty of health professions students, including those in medical, dental, and nursing schools, have been extensively researched. No such studies exist in the discipline of dental hygiene. The purpose of this study was to investigate the prevalence of cheating in Texas dental hygiene programs. Four hundred surveys were mailed to twenty Texas dental hygiene schools for graduating students to complete. A total of 289 usable surveys was returned for a response rate of 72.25 percent. Data were analyzed using SPSS with frequencies and chi-square tests. Findings from this study reveal that 86.5 percent of graduating Texas dental hygiene students have cheated a minimum of one time during matriculation. Students identified the demands of what they considered academic overload as the primary justification for cheating behavior.

    The 72nd Texas Legislature specifically delineated a 400-square-mile area in southeast Hudspeth County where siting activities would be limited. The Authority was given unprecedented powers of property access and eminent domain and expanded budget authority to conduct site selection, characterization, and licensing. In the summer of 1991, the Authority identified five general siting areas in the prescribed region, and in the fall of 1991, the Authority narrowed the siting area to one large ranch composed of about 16,000 acres--called the Faskin Ranch. Site characterization began in 1991 and will be complete by September 1993. In September 1991, Authority staff began preparing the license application and included all available information on the Faskin Ranch. At its February meeting, the Authority`s board directed staff to submit the license application to the Texas Water Commission (the new Texas radiation control agency). The license application was submitted on March 2, 1992, and on April 15, 1992, the Commission determined that the application was sufficiently complete to begin review. Discrete technical packages such as groundwater hydrology, surface water hydrology, design, etc., will be submitted to the agency for review on the completion of each package. A schedule has been developed to allow the regulators the maximum time possible to review critical technical areas while minimizing the total review period.

  7. Influence of Climate Oscillations on Extreme Precipitation in Texas

    2016-12-01

    Much research in the field of hydroclimatology is focusing on the impact of climate variability on hydrologic extremes. Recent studies show that the unique geographical location and the enormous areal extent, coupled with extensive variations in climate oscillations, have intensified the regional hydrologic cycle of Texas. The state-wide extreme precipitation events can actually be attributed to sea-surface pressure and temperature anomalies, such as Bermuda High and Jet Streams, which are further triggered by such climate oscillations. This study aims to quantify the impact of five major Atlantic and Pacific Ocean related climate oscillations: (i) Atlantic Multidecadal Oscillation (AMO), (ii) North Atlantic Oscillation (NAO), (iii) Pacific Decadal Oscillation (PDO), (iv) Pacific North American Pattern (PNA), and (v) Southern Oscillation Index (SOI), on extreme precipitation in Texas. Their respective effects will be determined for both climate divisions delineated by the National Climatic Data Centre (NCDC) and climate regions defined by the Köppen Climate Classification System. This study will adopt a weighted correlation approach to attain the robust correlation coefficients while addressing the regionally variable data outliers for extreme precipitation. Further, the variation of robust correlation coefficients across Texas is found to be related to the station elevation, historical average temperature, and total precipitation in the months of extremes. The research will shed light on the relationship between precipitation extremes and climate variability, thus aiding regional water boards in planning, designing, and managing the respective systems as per the future climate change.

    UTIG provides K-12 teachers with research experiences in field programs that involve UTIG scientists. I am a 6th-9th grade science teacher in Van Vleck, Texas and in April 2004 I sailed to the southeastern Caribbean aboard the R/V Maurice Ewing as a member of the BOLIVAR Project alongside scientists from the U.S. and Venezuela. Our goal was collect seismic data to image the crust and mantle beneath the Caribbean as part of a study of the tectonic processes accompanying different stages of the Caribbean arc/South America continental collision process. Throughout the 52-day cruise I worked as a watch stander, interpreted newly collected seismic reflection data, helped deploy the streamer, maintained a cruise blog (a chronological journal weblog documenting personal thoughts about my experience), spoke with students in Texas with the telephone on loan from Iridium Satellite Solutions, and responded to email inquiries from shore-based students. It was hard work, but most importantly, a voyage of discovery. With guidance from scientists and GK-12 Fellows at UTIG, I am using my experience and the data collected as the basis for K-12 curriculum resources, including learning activities and a video documentary. Support for my participation and post-cruise activities was provided by the NSF and the Trull Foundation in Texas. If given the opportunity to do this again, I would, without reservation!

    Leishmaniasis is a zoonotic disease caused by intracellular Leishmania protozoa that are transmitted by sandflies. The disease occurs in 3 forms: cutaneous, mucocutaneous, and visceral. Cutaneous leishmaniasis has been reported in cats in Europe and South America and in 1 cat from Texas. Leishmania mexicana is endemic in Texas and has been reported to cause cutaneous lesions in humans. This article describes the pathology of 8 biopsy cases of feline cutaneous leishmaniasis presented to the Texas Veterinary Medical Diagnostic Laboratory over a 3.5-year period. The median age of the cats was 3 years; each was presented with nodular, ulcerative lesions on the pinnae and less commonly on the muzzle and periorbital skin. Histologically, the lesions were nodular to diffuse histiocytic dermatitis with numerous amastigotes (2-4 μm) within macrophages and occasionally within the interstitium. Organisms were often contained within round, clear, intracellular vacuoles. In areas of necrosis, organisms were also free within the interstitium. The overlying epidermis was hyperkeratotic, hyperplastic, and often ulcerated. The organisms were not argyrophilic (Gomori methenamine silver), reacted poorly with periodic acid-Schiff reagent, and were inconsistently basophilic with Giemsa. Although not readily visible histologically, kinetoplasts were evident in amastigotes in cytologic preparations. The lesions were similar to those described for cutaneous L. mexicana infection in humans. In 5 of the 8 cats, Leishmania mexicana DNA was amplified from paraffin-embedded tissue by polymerase chain reaction and sequenced.

    Presented in this paper are: (1) historical background, (2) Federal and State regulatory basis and authority, and (3) justification for selected criteria and parameters which are currently used to evaluate the quality of topsoil-substitute materials and postmine soils in Texas. The specific parameters and concepts discussed include (1) acid- and toxic-forming materials (AFM and TFM), (2) quantification procedures for AFM and TFM, (3) procedures used to identify topsoil substitutes that are {open_quotes}equal to or more suitable than{close_quotes} existing premine native soils, and (4) current interpretations of what is meant by {open_quotes}the best available material to support revegetation{close_quotes} of surface-mined areas. To support these interpretations, reference is made throughout the paper to relevant sections of the (1) Texas Coal Mining Regulations (TCMR), (2) Surface Mining Control and Reclamation Act (SMCRA), and (3) Federal regulations promulgated by the Office of Surface Mining (OSM) to implement SMCRA. The success of the Texas reclamation program, as indicated by the quality of the reclaimed soils is also discussed. This success is partly attributed to the rigorous application of the quantification concepts and parameters discussed in this paper.

    Raccoons (n=590) were collected from October 1999 to August 2003 from 35 counties across Texas, USA, and gastrointestinal tracts were examined for Baylisascaris procyonis. We documented B. procyonis in central and eastern Texas. Baylisascaris procyonis occurred in 5.4% raccoons in Texas with an overall mean abundance and mean intensity of 0.4+/-0.1 and 7.4+/-2.3, respectively. Prevalence was higher in central Texas ecoregions and on clayey soil texture than other regions or soil textures of Texas. Mean parasite abundance was highest in the Postoak Savanna ecoregion located in central Texas. Our findings expanded the range of B. procyonis in Texas and confirmed that areas of Texas with clayey soil texture are more vulnerable to B. procyonis transmission. This study gives a better understanding of where B. procyonis may occur in Texas and which environmental characteristics are better suited for B. procyonis occurrence and transmission, especially in areas where likelihood of frequent human contact with raccoons and their feces increases.

    1996-01-01

    This report presents two techniques to estimate generalized skew coefficients used for log-Pearson Type III peak-streamflow frequency analysis of natural basins in Texas. A natural basin has less than 10 percent impervious cover, and less than 10 percent of its drainage area is controlled by reservoirs. The estimation of generalized skew coefficients is based on annual peak and historical peak streamflow for all U.S. Geological Survey streamflow-gaging stations having at least 20 years of annual peak-streamflow record from natural basins in Texas. Station skew coefficients calculated for each of 255 Texas stations were used to estimate generalized skew coefficients for Texas.

  14. USGS Zebra Mussel Monitoring Program for north Texas

    2012-01-01

    The U.S. Geological Survey (USGS) Zebra Mussel Monitoring Program for north Texas provides early detection and monitoring of zebra mussels (Dreissena polymorpha) by using a holistic suite of detection methods. The program is designed to assess zebra mussel occurrence, distribution, and densities in north Texas waters by using four approaches: (1) SCUBA diving, (2) water-sample collection with plankton tow nets (followed by laboratory analyses), (3) artificial substrates, and (4) water-quality sampling. Data collected during this type of monitoring can assist rapid response efforts and can be used to quantify the economic and ecological effects of zebra mussels in the north Texas area. Monitoring under this program began in April 2010. The presence of large zebra mussel populations often causes undesirable economic and ecological effects, including damage to water-processing infrastructure and hydroelectric powerplants (with an estimated 10-year cost of $3.1 billion), displacement of native mussels, increases in concentrations of certain species of cyanobacteria, and increases in concentrations of geosmin (an organic compound that results in taste and odor issues in water). Since no large-scale, environmentally safe eradication method has been developed for zebra mussels, it is difficult to remove established populations. Broad physicochemical adaptability, prolific reproductive capacity, and rapid dispersal methods have enabled zebra mussels, within a period of about 20 years, to establish populations under differing environmental conditions across much of the eastern part of the United States. In Texas, the presence of zebra mussels was first confirmed in April 2009 in Lake Texoma in the Red River Basin along the Texas-Oklahoma border. They were most likely introduced into Lake Texoma through overland transport from an infested water body. Since then, the presence of zebra mussels has been reported in both the Red River and Washita River arms of Lake Texoma, in

  18. Flash flood swift water rescues, Texas, 2005–2014

    Directory of Open Access Journals (Sweden)

    Vaidehi Shah

    2017-01-01

    Full Text Available Although rainfall patterns are complex and difficult to predict, climate models suggest precipitation in Texas will occur less frequently and with greater intensity in the future. In combination with rapid population growth and development, extreme rainfall events are likely to lead to flash floods and necessitate swift water rescues. Swift water rescues are used to retrieve person(s from swift water flowing at a rate of 1 knot or greater. Data were obtained from the Texas Fire Marshal’s Office and analyzed to describe spatial and temporal characteristics of rescues. Between 2005 and 2014, 3256 swift water rescues were reported from 136 of 254 (54% counties. Over half (54.6%, n = 1777 occurred in counties known as Flash Flood Alley, which includes Texas’ largest and fastest growing cities. Less than 1.0% (n = 18 were reported from 49 counties designated as completely rural, or with an urban population less than 2500. Increases in swift water rescues were seen between March and September and during major weather events such as tropical storms. Because county-level data was utilized and demographic data was missing in all but 2% (n = 47 of the incidents, our ability to identify populations at risk or target interventions in the future using this data is limited. Despite the frequency of flash flood events and swift water rescues in Texas, knowledge gaps persist that should be addressed through the conduct of interdisciplinary research by epidemiologists and climatologists and by disseminating evidence-based health education and safety programs, particularly in rapidly growing counties that make up Texas’ Flash Flood Alley.

    The number of uninsured Texas residents who rely on the medical emergency department as their primary health care provider continues to increase. Unfortunately, little information about the characteristics of this group of emergency department users is available. Using an administrative billing database, we conducted a descriptive study to examine the demographic and clinical features of 17,110 consecutive patients without medical insurance who presented to the emergency department of the University of Texas Medical Branch in Galveston over a 12-month period. We also analyzed the risk of multiple emergency department visits or hospitalization according to demographic characteristics. Twenty percent of the study population made two or more emergency department visits during the study period; 19% of the population was admitted to the hospital via the emergency department. The risk of multiple emergency department visits was significantly elevated among African Americans and increased in a stepwise fashion according to age. The risk of being hospitalized was significantly reduced among females, African Americans, and Hispanics. There was an age-related monotonic increase in the risk of hospitalization. Abdominal pain, cellulitis, and spinal disorders were the most common primary diagnoses in patients who made multiple emergency department visits. Hospitalization occurred most frequently in patients with a primary diagnosis of chest pain, nonischemic heart disease, or an affective disorder. Additional studies of emergency department usage by uninsured patients from other regions of Texas are warranted. Such data may prove helpful in developing effective community-based alternatives to the emergency department for this growing segment of our population. Local policymakers who are responsible for the development of safety net programs throughout the state should find this information particularly useful.

    Simons, James D; Smith, Charles R

    2009-03-01

    The Texas National Coastal Assessment (NCA) program began with the immediate challenge of integrating the NCA effort with Texas Parks and Wildlife Department's (TPWD) Coastal Fisheries Division and its existing probabilistic Fishery Independent Monitoring Program. Close coordination and detailed planning along with a novel two boat sampling operation helped to make this alliance work. Partnerships with National Estuary Programs and the Texas Commission on Environmental Quality (TCEQ) greatly improved coverage of the Texas coast over the initial fifty station design. Airboats, biobags, and polyvinyl chloride (PVC) corers were instrumental in overcoming numerous technical challenges. NCA data provide a more complete assessment of water and sediment quality than the traditional 305(b) report, with better spatial coverage and a measure of validity. There were differing patterns of PCBs, PAHs, DDTs and chlorinated pesticides, and metals such as mercury (Hg), arsenic (As), lead (Pb) and zinc (Zn) along the Texas coast. A confederation of Texas state agencies is considering ways to take advantage of probabilistic sampling designs to monitor the Texas coast. The TCEQ and TPWD are working on a joint project to redesign sediment and water quality monitoring that may serve as a springboard to a continuous monitoring program and opportunities for further improvement of ecosystem health assessment of the Texas coast.

    2005-05-01

    TABS was established in l995 to provide data to assess oil spill movement along Texas coast for the Texas General Land Office Oil Spill Prevention and Response Program. A system of nine automated buoys provide wind and current data in near real time. Two of these buoys are supported by the Flower Garden Banks Joint Industry Program. A TABS web site provides a public interface to view and download the data. A real time data analysis web page presents a wide variety of useful data products derived from the field measurements. Integration efforts now underway include transfer of buoy data to the National Data Buoy Center for quality control and incorporation into the Global Telecommunications Stream. The TGLO ocean circulation nowcast/forecast modeling system has been in continuous operation since 1998. Two models, POM and ROMS, are used to produce forecasts of near-surface wind driven currents up to 48 hours into the future. Both models are driven using wind fields obtained from the NAM (formerly Eta) forecast models operated by NOAA NCEP. Wind and current fields are displayed on websites in both static and animated forms and are updated four times per day. Under funding from the SURA/SCOOP program we are; 1) revamping the system to conform with the evolving Data Management and Communications (DMAC) framework adopted by the NSF Orion and OCEAN.US IOOS programs, 2) producing model-data comparisons, and 3) integrating the wind and current fields into the GNOME oil trajectory model used by NOAA/Hazmat. Academic research is planned to assimilate near real-time observations from TABS buoys and some 30-40 ADCP instruments scheduled to be mounted on offshore oil platforms in early 2005. Texas Automated Buoy System (TABS) and its associated modeling efforts provide a reliable source of accurate, up-to-date information on currents along the Texas coast. As the nation embarks on the development of an Integrated Ocean Observing System (IOOS), TABS will be an active participant

  7. Texas First Dental Home: A Snapshot after Five Years.

    Science.gov (United States)

    Solomon, Eric S; Voinea-Griffin, Andreea E

    2015-06-01

    Early caries is still the most prevalent disease of childhood. Its incidence continues to be high, despite recent progress in the amount of untreated caries. The disease is more prevalent in low socio-economic and minority groups. To address this issue, in 2008 Texas implemented the First Dental Home Program for Medicaid children from 6 to 35 months old. The program consists in providing up to 10 preventive and oral health education visits to children very early in life. A specific dental visit code and a bundled payment of $94 were offered to insure adequate dental provider participation. Little is known about the program results to date. This paper evaluates program development at 5 years. Two data sets on first dental home patients and providers were obtained from the Texas Department of Health Services. The data cover a 5-year period (3rd quarter of 2008 to end of 2nd quarter 2013). Program participants were geocoded and their distribution was compared to dental underserved areas. Program uptake over time and the relationship between provider and patient locations were also evaluated. The program covered 440,191 children between September 1st, 2011 and February 28th, 2013. All but two counties in Texas had at least one patient enrolled in the program. As expected, program uptake was higher in highly populated and economically disadvantaged counties. Forty-five percent of Texas licensed dentists participated in the program. The number of dental providers certified to provide first dental home services was highly correlated with the number of patients enrolled in the program (r = 0.893). The number of children participating in the program was between 20.4% and 23%. 29.7% of the first dental home patients had only one visit while only 17.1% had five or more visits. The number of patients and the number of visits per patient peaked at the end of 2011 and flatten thereafter. Many children benefited from the program since its rollout. However, despite considerable

    Lee, J.N.

    1986-01-01

    Most of the water needs of Tom Green County, Texas, are supplied by ground water; however, the city of San Angelo is supplied by surface water. Groundwater withdrawals during 1980 (latest year for which data are available) in Tom Green County totaled about 15,300 acre-feet, all derived from shallow aquifers. Shallow aquifers in this report refer to the ground-water system generally less than 400 feet deep that contains water with less than a 10,000 milligrams per liter concentration of dissolved solids; aquifers comprising this system include: The Leona, Comanche Peak, Trinity, Blaine, San Angelo, Choza, Bullwagon, Vale, Standpipe, and Arroyo aquifers.

    Winkler County, in west Texas, is adjacent to the southeast corner of New Mexico. Most of the county lies in the Pecos Valley; the remainder, in the northeastern part of the county, is part of the Llano Estacado, or the High Plains. Its principal industries are those related to the production and refining of oil, but ranching also is an important occupation. The county has an arid to semiarid climate, an area of about 887 square miles, and a population of about 12,000 in 1957.

    The objective of this study was to examine state radiation emergency response and to locate any areas of emergency planning in need of improvement. This report briefly presents a summary of laws and defining documents governing radiation emergency response, describes the existing and projected need for such response, and presents the authors' analyses of the evolution of state response plans and their application to radiation incidents. Three states' programs are discussed in detail: Illinois, Alabama, and Texas. These states were selected because they have quite different emergency-response programs. Therefore, these state programs provide a wide variety of approaches to state radiation emergency response.

    1957-01-01

    Galveston County, on the Texas gulf coast, is underlain by alternating beds of sand and clay. These sand and clay strata crop out in belts that roughly parallel the coastline and dip gently southeastward at an angle gre? +,er than the slope of the land, thereby creating artesian aquifers. The formations that yield potable water to wells are the Lissie formation, the "Alta Loma" sand and other sands of the Beaumont clay, and beach and dune sands of Recent aie. Most of the potable water is obtained on the mainland of Galveston County. The water from most wells on Galveston Island is highly mineralized.

    Science.gov (United States)

    Mech, L. David; Nowak, Ronald M.

    2010-01-01

    Skulls of wild Canis collected 2003–2004 in north-central Texas are morphometrically similar to a series taken there and in nearby areas in 1964–1971, which was considered to represent a population of Coyotes (C. latrans) modified through introgression from Red Wolves (C. rufus). A few of the new specimens closely resemble small examples of Red Wolves. Such affinity is supported by authoritative examination of living and videotaped animals. The persistence of influence of Red Wolves, long after presumed extirpation through hybridization and human persecution, may be relevant to wolf conservation.

    This project benefited the public by assisting manufacturing plants in the United States to save costly energy resources and become more profitable. Energy equivalent to over 75,000 barrels of oil was conserved. The Texas A&M University Industrial Assessment Center (IAC) visited 96 manufacturing plants and spent 101 days in those plants during the contract period from August 9, 2002, through November 30, 2006. Recommended annual energy savings for manufacturers were 37,400,000 kWh (127,600 MMBtu—site basis) of electricity and 309,000 MCF (309,000 MMBtu) of natural gas. Each manufacturer subsequently was surveyed, and based on these surveys reportedly implemented 79% of the electricity savings and 36% of the natural gas savings for an overall energy savings of 48% of recommended. Almost 800 (798) projects were recommended to manufacturers, and they accomplished two-thirds of the projects. Cost savings recommended were $12.3 million and implemented savings were $5.7 million or 47%. During the contract period our average time between site visit and report submittal averaged 46 days; and decreased from 48 days in 2003 to 44 days in 2006. Serving clients well and promptly has been a priority. We visited five ESA overflow clients during FY 06. The Texas A&M University IAC pioneered the presentation of air pollution information in reports, and includes NOx and CO2 reductions due to energy savings in all reports. We also experimented with formal PowerPoint BestPractices presentations called Lunchtime/Showtime in each plant and with delivering electronic versions of the report. During the period of the contract, the director served on the Texas Industries of the Future (IOF) Refining and Chemicals Committee, which oversaw the showcases in 2003 and 2006. The assistant director was the Executive Director of the International Energy Technology Conference held annually. The director and assistant director became qualified specialists in the Process Heating Assessment Scoping

    2004-08-01

    Time series analysis of water consumption patterns has been the subject of increasing attention in recent years. For many municipalities such efforts offer a means for developing potentially useful planning tools. Because data requirements are not extensive, model development is feasible for markets where information is limited. The work at hand examines the applicability of such a tool in El Paso, Texas, a growing metropolitan economy located in a semiarid region. Sample data are from January 1994 through December 2002. In addition to estimating a linear transfer function equation of water consumption in this city the model is subjected to a series of simulation benchmark tests.

  2. The Use of Medically Recommended Intensive Supervision (Medical Parole) in Texas.

    Science.gov (United States)

    Ethridge, Philip A; White, Thomas G

    2015-10-01

    For more than 20 years, lawmakers in Texas acknowledged that offenders with special needs such as the elderly, physically handicapped, and mentally impaired who are housed in the Texas Department of Criminal Justice presented challenges in health care and cost. In response to these perceived needs, the Texas legislature created "medically recommended intensive supervision" (MRIS) to permit the early release of eligible offenders. This article examines how and why the MRIS law was implemented. It also discusses how MRIS is being utilized in Texas. Next, it delineates the MRIS process an offender must endure. The article elaborates on recent legislative attempts to amend the MRIS law. Finally, several conclusions about the use of MRIS in Texas are discussed. © The Author(s) 2015.

    1982-01-01

    We conducted a study in 1978-1980 of the nesting ecology of Roseate Spoonbills (Ajaia ajaja) in a relatively polluted environment at Nueces Bay, Texas. For 154 marked nests, the average clutch size was 3.0 eggs; 73% of the eggs hatched, and 87% of the nests were successful (hatched at least 1 young). The average nest success rate (total fledglings:total eggs) was 50% or 1.5 fledglings per total nests. Incubation began the day after the first egg was laid, and the incubation period for each egg was 22 days. Eggs hatched in the order that they were laid; the first and second eggs hatched on consecutive days, and the second, third, and fourth eggs hatched every other day. Nest composition and size were highly consistent, but nest placement varied considerably and was dependent on the vegetative configuration of the dredge-material islands. Growth rate of nestlings conformed to a 'standard' growth curve, where body weight of nestlings at fledging equaled that of adults. There was no difference in weight gain among siblings based on actual age. Nestlings fledged at about 6 weeks of age, when feather development was complete. At fledging, the bills of juveniles had almost reached adult width, but bill length was only 67% that of adults. In general, environmental pollutants were low (Nueces Bay, Texas, though the area is surrounded by industries and agricultural lands. Apparently, spoonbills are less sensitive to these contaminants than are other aquatic species

  5. The Texas Dental Association and advocacy: a TDA president's perspective.

    Eggleston, Frank K; Jeske, Arthur H

    2008-08-01

    The TDA can take pride in the joint efforts of its leadership, its grassroots members, and its elected representatives in the middle of the decade of the 1990's. When asked about his legacy for the leadership of our organization, Dr. Eggleston emphatically states, "You have to act. You have to do the right thing even when you have critics and detractors." More recently, during his campaign for ADA President-elect, he constantly stressed the importance of our relationship with each other. Our relationship, in Dr. Eggleston's words now and during his TDA presidency, "is more important than all issues put together". As this brief retrospective illustrates, the issues faced by dentists and the TDA are never trivial and are always tied to the legislative process. Political advocacy by our association is, therefore, our first priority now, no less so than it was in the mid-1990's. As described in the recent "TDA Report Card" on our legislative agenda for the 80th Texas Legislature, our challenges continue unabated, but these challenges are answered, and in many cases, successfully overcome as a result of our advocacy efforts. Our need for constant involvement in the legislative process is perhaps best summarized by advice given to Dr. Eggleston by Senator (and oral surgeon) David Sibley at the 1995 TDA Annual Session. Senator Sibley complimented TDA on its achievements during the 1995 Texas legislative session, and added "but you've got to keep your garden weeded."

  6. Environment of deposition of Clear Fork Formation: Yoakum County, Texas

    Energy Technology Data Exchange (ETDEWEB)

    Moore, B.K.

    1987-05-01

    The Clear Fork Formation is Permian (Leonardian) in age and constitutes a major oil-bearing unit in the Permian basin of west Texas. In Yoakum County, west Texas, the upper Clear Fork carbonates record a subtidal upward-shoaling sequence of deposition. A small bryozoan-algal patch reef is situated within these carbonates near the southern edge of the North Basin platform. The reef is completely dolomitized, but paramorphic replacement has facilitated a study of the paleoecology, lateral variations, and community succession within this buildup. Build-ups of this type are scarcely known in strata of Permian age. The reef was apparently founded on a coquina horizon at the base of the buildup. The reef apparently had a low-relief, dome-shaped morphology. The trapping and binding of sediment by bryozoa appear to have been the main constructional process. A significant role was also played by encrusting forams and the early precipitation of submarine cements, both of which added rigidity to the structure. The reef also contains a low-diversity community of other invertebrates. Algal constituents predominate at the basinward edge of the buildup. The reef was formed entirely subaqueously on a broad, relatively shallow tropical marine carbonate shelf environment. An understanding of the lithofacies distribution and paragenesis within this sequence will provide information on porosity variations and the nature and distribution of permeability barriers. Such information is useful in reservoir modeling studies and for secondary recovery techniques in shelf-edge carbonate reservoirs of this type.

    2016-01-01

    Full Text Available The purpose of this study was to inform decision makers at state and local levels, as well as property owners about the amount of water that can be supplied by rainwater harvesting systems in Texas so that it may be included in any future planning. Reliability of a rainwater tank is important because people want to know that a source of water can be depended on. Performance analyses were conducted on rainwater harvesting tanks for three Texas cities under different rainfall conditions and multiple scenarios to demonstrate the importance of optimizing rainwater tank design. Reliability curves were produced and reflect the percentage of days in a year that water can be supplied by a tank. Operational thresholds were reached in all scenarios and mark the point at which reliability increases by only 2% or less with an increase in tank size. A payback period analysis was conducted on tank sizes to estimate the amount of time it would take to recoup the cost of installing a rainwater harvesting system.

  8. Red-shouldered hawk nesting habitat preference in south Texas

    Strobel, Bradley N.; Boal, Clint W.

    2010-01-01

    We examined nesting habitat preference by red-shouldered hawks Buteo lineatus using conditional logistic regression on characteristics measured at 27 occupied nest sites and 68 unused sites in 2005–2009 in south Texas. We measured vegetation characteristics of individual trees (nest trees and unused trees) and corresponding 0.04-ha plots. We evaluated the importance of tree and plot characteristics to nesting habitat selection by comparing a priori tree-specific and plot-specific models using Akaike's information criterion. Models with only plot variables carried 14% more weight than models with only center tree variables. The model-averaged odds ratios indicated red-shouldered hawks selected to nest in taller trees and in areas with higher average diameter at breast height than randomly available within the forest stand. Relative to randomly selected areas, each 1-m increase in nest tree height and 1-cm increase in the plot average diameter at breast height increased the probability of selection by 85% and 10%, respectively. Our results indicate that red-shouldered hawks select nesting habitat based on vegetation characteristics of individual trees as well as the 0.04-ha area surrounding the tree. Our results indicate forest management practices resulting in tall forest stands with large average diameter at breast height would benefit red-shouldered hawks in south Texas.

    To investigate race and poverty in areas where oil and gas wastewater disposal wells, which are used to permanently inject wastewater from hydraulic fracturing (fracking) operations, are permitted. With location data of oil and gas disposal wells permitted between 2007 and 2014 in the Eagle Ford area, a region of intensive fracking in southern Texas, we analyzed the racial composition of residents living less than 5 kilometers from a disposal well and those farther away, adjusting for rurality and poverty, using a Poisson regression. The proportion of people of color living less than 5 kilometers from a disposal well was 1.3 times higher than was the proportion of non-Hispanic Whites. Adjusting for rurality, disposal wells were 2.04 times (95% confidence interval = 2.02, 2.06) as common in areas with 80% people of color or more than in majority White areas. Disposal wells are also disproportionately sited in high-poverty areas. Wastewater disposal wells in southern Texas are disproportionately permitted in areas with higher proportions of people of color and residents living in poverty, a pattern known as "environmental injustice."

    The objective of this study was to develop and calibrate a groundwater model for a 4-county area in the Texas High Plains of the Ogallala Aquifer Region. This study is a major component of a comprehensive regional analysis of groundwater depletion in the Ogallala Aquifer Region with the purpose of understanding short- and long-term effects of existing and alternative land use scenarios on groundwater changes. A comprehensive geographic information system (GIS) database was developed for this purpose that included a recent land cover map. This 2008 land cover map was developed using Landsat satellite imagery with ground-truth points for Dallam, Sherman, Hartley, and Moore Counties in Texas. Other GIS layers included aquifer elevation contours, surficial geology, hydraulic conductivity contours, saturated thickness areas, well locations and piezometric heads, aquifer discharge and recharge areas, topography, hydrographic data, ecological regions, and soil type data. The hydrologic simulations were done using MODFLOW. Anticipated outcomes from this modeling effort include the effect of change in land use/land cover on sustainability of the aquifer life in the study region. Our results will be used to develop strategies to conserve groundwater in the Ogallala Aquifer beneath Central High Plains and improve regional water planning.

    Groundwater quality degradation is a major threat to sustainable development in Texas. The aim of this study was to elucidate spatiotemporal patterns of groundwater fluoride (F) contamination in different water use classes in 16 groundwater management areas in Texas between 1960 and 2010. Groundwater F concentration data were obtained from the Texas Water Development Board and aggregated over a decadal scale. Our results indicate that observations exceeding the drinking water quality threshold of World Health Organization (1.5 mg F L) and secondary maximum contaminant level (SMCL) (2 mg F L) of the USEPA increased from 26 and 19% in the 1960s to 37 and 23%, respectively, in the 2000s. In the 2000s, F observations > SMCL among different water use classes followed the order: irrigation (39%) > domestic (20%) > public supply (17%). Extent and mode of interaction between F and other water quality parameters varied regionally. In western Texas, high F concentrations were prevalent at shallower depths (Texas, higher F concentrations occurred at greater depths (>50 m) and were correlated with HCO and chloride anions. A spatial pattern has become apparent marked by "excess" F in western Texas groundwaters as compared with "inadequate" F contents in rest of the state. Groundwater F contamination in western Texas was largely influenced by groundwater mixing and evaporative enrichment as compared with water-rock interaction and mineral dissolution in the rest of the state.

  15. Applications of MODIS satellite data and products for monitoring air quality in the state of Texas

    Science.gov (United States)

    Hutchison, Keith D.

    The Center for Space Research (CSR), in conjunction with the Monitoring Operations Division (MOD) of the Texas Commission on Environmental Quality (TCEQ), is evaluating the use of remotely sensed satellite data to assist in monitoring and predicting air quality in Texas. The challenges of meeting air quality standards established by the US Environmental Protection Agency (US EPA) are impacted by the transport of pollution into Texas that originates from outside our borders and are cumulative with those generated by local sources. In an attempt to quantify the concentrations of all pollution sources, MOD has installed ground-based monitoring stations in rural regions along the Texas geographic boundaries including the Gulf coast, as well as urban regions that are the predominant sources of domestic pollution. However, analysis of time-lapse GOES satellite imagery at MOD, clearly demonstrates the shortcomings of using only ground-based observations for monitoring air quality across Texas. These shortcomings include the vastness of State borders, that can only be monitored with a large number of ground-based sensors, and gradients in pollution concentration that depend upon the location of the point source, the meteorology governing its transport to Texas, and its diffusion across the region. With the launch of NASA's MODerate resolution Imaging Spectroradiometer (MODIS), the transport of aerosol-borne pollutants can now be monitored over land and ocean surfaces. Thus, CSR and MOD personnel have applied MODIS data to several classes of pollution that routinely impact Texas air quality. Results demonstrate MODIS data and products can detect and track the migration of pollutants. This paper presents one case study in which continental haze from the northeast moved into the region and subsequently required health advisories to be issued for 150 counties in Texas. It is concluded that MODIS provides the basis for developing advanced data products that will, when used in

    2005-09-01

    Full Text Available Introduction The purpose of this study was to investigate the predictors of self-rated health status for Texas adults using the current 2003 Behavioral Risk Factor Surveillance System data. Self-rated health is generally accepted as a valid measure of health status in population studies, and understanding its correlates may help public health professionals prioritize health-promotion and disease-prevention interventions. Methods The two research questions addressed by this study involved the predictors of self-rated health: 1 "Do demographic characteristics, health care coverage, leisure-time physical activity, and body mass index predict self-rated health status for Texas residents aged 18 to 64 years?” and 2 “Does choice of interview language (English vs Spanish predict self-rated health status for Texas residents of Hispanic ethnicity aged 18 to 64 years?” Key analysis variables were identified, and descriptive statistics were used to describe the major variables and determine whether the number of respondents for each variable was sufficient for analysis. Multivariate regression analysis was used to assess the variables. Results Multiple logistic regression analysis (controlling for diabetes and arthritis of the self-rated health predictors indicated that older age, lack of health care coverage, lack of a college education, being Hispanic, having a lower income, obesity, and not exercising explained 19.4% of the variance of fair and poor self-rated health. The interview language (English or Spanish, age, sex, education, income, obesity, health insurance coverage, and physical activity (controlling for chronic illness explained 22.8% of the variance in fair and poor self-rated health for Hispanic respondents. Conclusion The results of this study suggest that a college education, a lower body mass index, non-Hispanic ethnicity, and participation in physical activity are associated with good, very good, or excellent self-rated health

    Pollutant emissions in the Texas-Mexico border were investigated using an emission database that covers 25 Texas counties and the states of Coahuila, Chihuahua, Nuevo Leon and Tamaulipas in Mexico. Major emissions are from energy generation, mainly from two coal-fired facilities in Coahuila, which also generate most of carbon dioxide. Texas exhibits a larger concentration of sources; around Laredo and the Lower Rio Grande Valley and a sugarcane mill is a significant contributor to particles emissions. In Mexico the minerals and metals industries are the second major contributors to emissions, especially particles. Fossil fuel production is the main source of VOCs.

    Highlights: • The KS-2 and KS-4 steam explosion experiments were analyzed by TEXAS-VI. • The coarse mixing status up to the explosion triggering time was well predicted by TEXAS-VI. • The predicted dynamic explosion pressure was in good agreement with the experimental results. - Abstract: TEXAS-VI is a transient, three-field, one-dimensional mechanistic model for the steam explosion phenomena. A fuel solidification model and associated fragmentation criteria of the solidifying particle for both the mixing phase and explosion phase were developed and incorporated into TEXAS-VI to account for solidification. In the present study, TEXAS-VI was used to analyze the KS-2 and KS-4 steam explosion experiments, which were performed in the KROTOS facility as part of the OECD-SERENA-2 program. In the simulation, the KROTOS experimental facility was modeled as Eulerian control volumes based on the facility geometry. The molten corium jet was divided up into a series of LaGrangian master particles equal to the initial jet diameter. Both the mixing phase and the explosion phase of the experiments were simulated by TEXAS-VI. Comparison to test data indicates that the fuel jet kinematics and the vapor volume during the mixing phase were well predicted by TEXAS-VI. The TEXAS-VI prediction of the dynamic explosion pressure at different axial locations in the test was also in good agreement with the experimental results. The maximum pressure of KS-2 and KS-4 predicted by TEXAS-VI were 16.7 MPa and 41.9 MPa, respectively. The KS-4 maximum steam explosion pressure predicted by TEXAS-VI was higher than that of KS-2, which was consistent with experiment observation. The observed differences of the dynamic explosion pressure between the KS-2 and KS-4 experiments were also successfully simulated by TEXAS-VI. This suggests that TEXAS-VI is able to analyze the effect of prototypic melt compositions on the steam explosion phenomena. Additional benchmarking and evaluations are ongoing.

    Surprisingly, from 1997 to 2010 Texas RGDP in oil and gas extraction was strongly negatively correlated with oil prices and with factors of production such as employment and the drilling rig count. It also had a slight negative correlation with physical production of oil and gas. In Texas the oil and gas sector is large and volatile enough to have a significant influence on overall RGDP growth so that when oil prices spike up (down) Texas RGDP generally weakens (strengths), which is in contra...

    Attempts to stimulate marginal gas producers in Sutton County, Texas, has provided an opportunity to evaluate several types of stimulation fluids on a comparative basis. The fluids used included water-base, oil-base, and acid-base fluids. A thorough study of the production history of wells following treatment demonstrates the effectiveness of the different fluids on a long term basis. Conclusions drawn from this study provide a guide to selection of fracture fluids for tight gas sands. Cost-performance factors are explored as they apply to stimulation of marginal gas production and further conclusions are drawn concerning the importance of formation damage as a function of formation petrophysical properties. Examples are shown to indicate formation damage is a factor to consider in fracturing tight sands but performance comprises may be made in the choice of fluid to obtain maximum frac penetration.

    Healthy diet and weight control are important for elders and senior centers (SCs). The authors consider effects of SCs on attendee nutrition and health and efforts to improve diets and weight. Data derive from surveys in 2006 (N = 798) and 2007 (N = 742) at 21 multipurpose SCs in Tarrant County, Texas, supplemented with data from 2012 (N = 1,402). Measures included attendee agreement that SC meals improved nutrition, improved health, attempts to improve diets, and success in controlling weight. Cumulative and binary logistic regression methods were employed. SC attendance and social engagement explained agreement that SC meals improved nutrition and health but were not shown to predict changes in diet or weight control. Findings suggest success of SC programs, as well as physician recommendations, in influencing attendee nutritional behavior and perceptions of nutrition and health effects. Practice recommendations include SC collaborations with local health providers to promote attendee nutritional health.

    Sixteen hundred waterfowl, mostly Canada Geese, died near Etter, Texas, in late January 1981 from anticholinesterase poisoning. Winter wheat in the area of the die-off had been treated with organophosphate insecticides to control greenbugs. Cholinesterase (ChE) levels in brains of a sample of geese found dead were 75% below normal, enough to account for death (Ludke et al. 1975). The gastrointestinal (G I) tracts of geese found dead were packed with winter wheat; gas chromatography techniques identified parathion and methyl parathion in the GI tract contents. Residues of both chemicals were confirmed by mass spectrometry. We recommend that less toxic materials, such as malathion, be used on grain crops when waterfowl are in the vicinity of treatment.

    The solar energy facility located at the North Hampton Park Recreation and Health Center, Dallas, Texas is presented. The solar energy system is installed in a single story (two heights), 16,000 sq ft building enclosing a gymnasium, locker area, and health care clinic surrounded by a recreational area and athletic field. The solar energy system is designed to provide 80 percent of the annual space heating, 48 percent of the annual space cooling, and 90 percent of the domestic hot water requirements. The system's operation modes and performance data acquisition system are described. The system's performance during the months of June, July, August, September, and October of 1979 are presented and show a negative savings of energy. Experience to date indicates however that the system concept has promise of acceptable performance. It is concluded that if proper control and sequencing components was maintained, then the system performance would improve to an acceptable level.

    This paper evaluates how the distribution of applicant and enrollee attributes at seven Texas universities changed after the Hopwood decision and the implementation of a policy guaranteeing admission to students with high class ranks. We analyze changes in the distributions of test scores and high school class ranks for underrepresented minority groups as well as white and Asian American applicants across institutions and between admission regimes. We show that these admissions policy changes, which have direct effects on only the most selective institutions, have substantial indirect effects at other institutions. Average test scores of applicants to less selective institutions rose following the change in admission criteria, as students with high test scores who did not qualify for the admission guarantee applied to a broader set of institutions. Furthermore, as the share of high rank applicants at UT-Austin rose, the pre-Hopwood assent in the test scores of their applicants stagnated. PMID:23335823

    Fog samples were collected in two population centers of the US Gulf Coast (Houston, Texas and Baton Rouge, Louisiana) using Caltech active strand cloud collectors. A total of 32 fogwater samples were collected in Baton Rouge (November 2004-February 2005) and Houston (February 2006). These samples were analyzed for pH, total and dissolved organic carbon, major inorganic ions, and a variety of organic compounds including organic acids, aromatics, carbonyls, and linear alkanes. Fogs in both environments were of moderate density, with typical fog liquid water contents clouds in the eastern US. Total organic carbon concentrations were much higher in Houston fogs than in Baton Rouge fogs. Efforts to speciate dissolved organic carbon (DOC) reveal large contributions from organic acids and carbonyls, with smaller contributions from other organic compound families including aromatics, alkanes, amides, and alcohols. Approximately 40% of the fog DOC was unspeciated in samples from both study locations.

    Because an energetic fuel-coolant interaction may be a safety hazard, experiments are being conducted to investigate the fuel-coolant mixing/quenching process (FARO) as well as the energetics of vapor explosion propagation for high temperature fuel melt simulants (KROTOS, WFCI, ZrEX). In both types of experiments, the dynamic breakup of the fuel is one of the key aspects that must be fundamentally understood to better estimate the magnitude of the mixing/quenching process or the explosion energetics. To aid our understanding the TEXAS fuel-coolant interaction computer model has been developed and is being used to analyze these experiments. Recently, the models for dynamic fuel fragmentation during the mixing and explosion phases of the FCI have been improved by further insights into these processes. The purpose of this paper is to describe these enhancements and to demonstrate their improvements by analysis of particular JRC FCI data. (author)

    Emmert, Sonny

    The composition of precipitation reflects the transport of particles from varying air mass source regions as well as input from local environmental and anthropogenic activities. Air research in El Paso, TX, U.S.A/Ciudad Juarez, Chihuahua, Mexico has been traditionally limited to studies of local inputs of air pollution; no transition has been made to studying the scavenging, washout, and transport of pollutants by precipitation. The goal of this research project was to identify transported pollutants in precipitation, and determine if there were any health and ecological implications. The research investigated biological, chemical, and geological constituents in precipitation samples collected between September 2004 and October 2005. A variety of analysis techniques were used to determine composition of the precipitation. These techniques included bacterial and fungal plate counts, inductively coupled plasma/mass spectrometry, ion chromatography, transmission electron microscopy, scanning electron microscopy, and electron microprobe analysis. Samples were collected from an urban site in El Paso, Texas at the campus of the University of Texas at El Paso. Wet only samples were the target of the sample collection. Particulate matter <10 microns was correlated with fungal growth while particulate matter < 2.5 microns was correlated with bacterial growth in analyzed samples. Microscopy methods revealed new techniques in particle characterization, evidence of anthropogenic influence, and a wide variety of particle compositions. The ionic chemistry results reflected elevated levels of ions as well as an overall alkalinity of rainwater samples. Elemental analysis of the inorganic fraction suggested elevated enrichment of Phosphorus in the study area and possible ratios for transport identification of southwestern dust storms.

  11. Aflatoxin contamination in corn sold for wildlife feed in texas.

    Supplemental feeding with corn to attract and manage deer is a common practice throughout Texas. Other species, including northern bobwhites (Colinus virginianus), are commonly seen feeding around supplemental deer feeders. In many cases, supplemental feeding continues year-round so feed supply stores always have supplemental corn in stock. Fluctuating weather and improper storage of corn can lead to and/or amplify aflatoxin contamination. Due to the recent decline of bobwhites throughout the Rolling Plains ecoregion of Texas, there has been interest in finding factors such as toxins that could be linked to their decline. In this study, we purchased and sampled supplemental corn from 19 locations throughout this ecoregion to determine if aflatoxin contamination was present in individual bags prior to being dispersed to wildlife. Of the 57 bags sampled, 33 bags (approximately 58%) contained aflatoxin with a bag range between 0.0-19.91 parts per billion (ppb). Additionally, three metal and three polypropylene supplemental feeders were each filled with 45.4 kg of triple cleaned corn and placed in an open field to study long-term aflatoxin buildup. Feeders were sampled every 3 months from November 2013-November 2014. Average concentration of aflatoxin over the year was 4.08 ± 2.53 ppb (±SE) in metal feeders, and 1.43 ± 0.89 ppb (±SE) in polypropylene feeders. The concentration of aflatoxins is not affected by the type of feeder (metal vs polypropylene), the season corn was sampled, and the location in the feeder (top, middle, bottom) where corn is sampled. It is unlikely that corn used in supplemental feeders is contributing to the bobwhite decline due to the low levels of aflatoxin found in purchased corn and long-term storage of corn used in supplemental feeders.

  12. High energy physics program at Texas A and M University

    The Texas A M experimental high energy physics program continued to reach significant milestones in each of its research initiatives during the course of the past year. We are participating in two major operating experiments, CDF and MACRO. In CDF, the Texas A M group has spearheaded the test beam program to recalibrate the Forward Hadron Calorimeter for the upcoming CDF data run, as well as contributing to the ongoing analysis work on jets and b-quarks. In MACRO, we have assisted in the development of the final version of the wave form digitizing system being implemented for the entire scintillator system. The construction of the first six supermodules of the detector has been completed and all six are currently taking data with streamer chambers while four have the completed scintillator counter system up and running. We have built and tested prototypes of a liquid-scintillator fiber calorimeter system, in which internally reflecting channels are imbedded in a lead matrix and filled with liquid scintillator. This approach combines the performance features of fiber calorimetry and the radiation hardness of liquid scintillator, and is being developed for forward calorimetry at the SSC. The microstrip chamber is a new technology for precision track chambers that offers the performance required for future hadron colliders. The theoretical high energy physics program has continued to develop during the past funding cycle. We have continued the study of their very successful string-derived model that unifies all known interactions; flipped SU(5), which is the leading candidate for a TOE. Work has continued on some generalizations of the symmetries of string theory, known as W algebras. These are expected to have applications in two-dimensional conformal field theory, two-dimensional extensions of gravity and topological gravity and W-string theory.

  13. Herbivory on shoalgrass by wintering redheads in Texas

    1994-01-01

    An estimated 80% of redheads (Aythya americana) winter on the Laguna Madre of south Texas and Mexico and feed almost exclusively on shoalgrass (Halodule wrightii) rhizomes. Shoalgrass abundance has decreased by 60% over the past 30 years, and because the effects of shoalgrass loss on wintering redheads are unknown, we initiated a study to define habitat selection criteria and document the effect of wintering redheads on shoalgrass in the lower Laguna Madre, Texas. Redheads consumed an average of 75% of shoalgrass rhizome biomass at collection sites each winter. When rhizome biomass was grazed to a mean biomass of ltoreq 0.18 g dry mass/core (approximately 10 g dry mass/ml), shoalgrass did not recover to its previous level the following growing season. Thirty-three percent of the sites (10) were grazed below 0.18 g dry mass/core during both years of the study, while 64% (19) were grazed below 0.18 g during 1 or the other of the 2 winters. Ramet number was positively correlated (P lt 0.001, r-2 = 0.54) with rhizome biomass; however, this relationship was influenced by grazing intensity. Heavy grazing reduced the amount of rhizome attached to each ramet compared with ungrazed ramets. Grazing had no effect on root biomass (P = 0.388), rhizome moisture content (P = 0.553), or soil magnesium, phosphorous, and potassium (P = 0.102, 0.499, 0.162, respectively). Redhead presence increased (P = 0.042) soil nitrogen levels. Foraging areas selected by redheads within the lower Laguna Madre had lower (P = 0.026) salinities (24 ppt) than areas not selected (35 ppt). Redheads did not select foraging areas in relation to crude protein levels in rhizomes. Shoalgrass habitat in the Laguna Madre should be protected from further losses and enhanced where possible.

    The objective of this project is to evaluate the feasibility of carbon dioxide (CO{sub 2}) sequestration in Texas low-rank coals and to determine the potential for enhanced coalbed methane (CBM) recovery as an added benefit of sequestration. The main objectives for this reporting period were to further characterize the three areas selected as potential test sites, to begin assessing regional attributes of natural coal fractures (cleats), which control coalbed permeability, and to interview laboratories for coal sample testing. An additional objective was to initiate discussions with an operating company that has interests in Texas coalbed gas production and CO{sub 2} sequestration potential, to determine their interest in participation and cost sharing in this project. Well-log data are critical for defining depth, thickness, number, and grouping of coal seams at the proposed sequestration sites. Therefore, we purchased 15 well logs from a commercial source to make coal-occurrence maps and cross sections. Log suites included gamma ray (GR), self potential (SP), resistivity, sonic, and density curves. Other properties of the coals in the selected areas were collected from published literature. To assess cleat properties and describe coal characteristics, we made field trips to a Jackson coal outcrop and visited Wilcox coal exposures at the Sandow surface mine. Coal samples at the Sandow mine were collected for CO{sub 2} and methane sorption analyses. We contacted several laboratories that specialize in analyzing coals and selected a laboratory, submitting the Sandow Wilcox coals for analysis. To address the issue of cost sharing, we had fruitful initial discussions with a petroleum corporation in Houston. We reviewed the objectives and status of this project, discussed data that they have already collected, and explored the potential for cooperative data acquisition and exchange in the future. We are pursuing a cooperative agreement with them.

    Full Text Available Background Exposure to secondhand smoke is an important preventable cause of illness and death. A Smoke-Free Paso del Norte Coalition in El Paso, Texas, led a drive to introduce an ordinance to protect nonsmoking persons from the health effects of secondhand smoke in public places. The ordinance was introduced in April 2001 and was passed on June 26, 2001. Context El Paso is the fifth largest city in Texas and the largest border city in the United States. It is the 10th poorest city in the United States; 37% of its residents do not have health insurance. Seventy-eight percent of El Paso’s residents are Hispanic/Latino. A large percentage of El Paso’s restaurant and bar workers are recent immigrants from Mexico. Methods Campaign activities included a letter-writing campaign to the El Paso Times, petition gathering, community outreach education, meetings with city council members, print and television advertising, a proactive media advocacy campaign, and a youth rally. Consequences One month after the ordinance went into effect, an opinion poll found solid support for the new ordinance. Another survey conducted in December 2002 also found a 22% decline in adult smoking, from 22.1% in 1996 to 17.3% at the time of the survey. Interpretation The El Paso campaign is an example of a successful grassroots campaign. El Paso’s campaign relied on direct organizing to identify, recruit, and mobilize supporters, and involved relatively little paid media or paid advocacy efforts. These lessons are transferable to other communities, and the El Paso coalition serves as a model for developing a diverse, representative coalition in a predominantly Mexican American community.

    Prescribed fire is widely applied for habitat management in coastal ecosystems. Fire management plans typically list a variety of objectives for prescribed burning, including succession management, promotion of native flora and fauna, providing habitat for species of importance, wildfire risk reduction (fuels management), as well as reduction and/or prevention of invasive species. In most cases, the information needed to determine the degree to which management objectives are met is not available. This study sought to provide an assessment of key objectives of fire management at the U.S. Fish and Wildlife Service (USFWS) Texas Mid-coast National Wildlife Refuge Complex. The main purpose of this work was to provide information and recommendations that will support Region 2 of the USFWS in the conduct of their fire and habitat management activities in the Western Gulf coast region. There were four main components of this project: (1) a historical analysis of the role of fire in this ecosystem, (2) the development of standard methodology for assessing and monitoring fire effects in this system, (3) an evaluation of the effects of prescribed burning on the habitat being managed, and (4) an evaluation of the effects of burning on select fauna of special concern. A team of researchers, including some from the U.S. Geological Survey (USGS), Southeast Missouri State University, and Louisiana State University were involved in the various components of this project. Extensive support by USFWS personnel, both at the Texas Mid-coast National Wildlife Refuge Complex and in the Regional Office (Region 2, USFWS), was a key component in this work. Data from the three years of this study were combined with the results of previous USGS studies performed at the site to strengthen our conclusions.

    Full Text Available A paper appearing in this journal by Klein, Hamilton, McCaffrey and Stecher (2000 attempted to raise serious questions about the validity of the gains in student performance as measured by Texas' standardized test, the Texas Assessment of Academic Skills (TAAS. Part of their analysis was based on the results of three tests which they administered to 2,000 fifth grade students in 20 Texas schools. Although Klein et al. indicated that the 20 schools were not selected in a way which would insure that they were representative of the nearly 3,000 Texas schools that enrolled fifth graders, generalizations based upon the results for those schools were nonetheless offered. The purpose of this short paper is to demonstrate just how unrepresentative the 20 schools used by Klein et al. actually were, and in so doing to cast doubt on certain of their conclusions.
