    1998-06-01

    Without a doubt, a primary feature of the 1998 Spring National Meeting in Dallas was the High School Program, which was organized by George Hague, and the impact that the Texas teachers had on other participants. Over 150 teachers registered for the meeting and participated in the program. Their organizational skills were used to reinstitute the High School/College Interface Luncheon. (The High School/College Interface Luncheon will also be held at the Fall ACS Meeting in Boston.)

  8. President Kennedy in Dallas: Dealey Plaza memorialized

    NASA Astrophysics Data System (ADS)

    Asmus, John F.

    2007-07-01

    The assassination of US President John F. Kennedy on November 22, 1963 transformed the US political landscape as well as the trajectory of subsequent world history. The venue of that tragic event in Dallas was Dealey Plaza, encompassing the "grassy knoll" and the adjacent book-depository and courthouse buildings. For the past forty years the site has undergone a series of conservation/preservation projects in order to make it more suitable for those visiting either in homage or out of curiosity. One such project concerned the deterioration of ironwork within the "Old Red Courthouse". The building architect noted that both stairway railings and floor-support trusses were corroding and deteriorating at accelerating rates. In most situations of this sort the iron would be sandblasted and repainted. However, in this instance sandblasting was inappropriate due to environmental concerns and logistical limitations. Furthermore, historical authenticity criteria dictated that the metal be preserved with its original unpainted finish. In order to avoid excessive floor loading (in this fragile old building) and the generation significant environmental air pollution (within urban Dallas) the general contractor (Avery Mays, Inc.) opted to evaluate photonic divestment. Both laser cleaning and laser glazing were assessed for efficacy and cost effectiveness. Xenon-flashlamp irradiation was evaluated both with and without citric acid augmentation. Citric acid matrix-assisted flashlamp treatment was selected for the preservation of the courthouse ironwork. This decision was based on three advantages over laser treatments: higher speed and cost effectiveness, preservation of the historic "Oliver Foundry" logo markings, and the chemical passivation and rust resistance of the final surface patina.

  10. Iterated transportation simulations for Dallas and Portland

    SciTech Connect

    Nagel, K.; Simon, P.; Rickert, M.; Esser, J.

    1998-09-02

    The goal of the TRansportation ANalysis and SIMulation System (TRANSIMS) is to combine the most important aspects of human decision-making related to transportation, from activities planning (sleep, work, eat, shop,...) via modal and route planning to driving, into a single, consistent methodological and software framework. This is meant to combine the functionalities of activities-based travel demand generation, modal choice and route assignment, and micro-simulation. TRANSIMS attempts to employ advanced methodologies in all these modules. Yet, it is probably the overall framework that is the most important part of this attempt. It is, for example, possible to replace the TRANSIMS microsimulation by another micro-simulation that uses the same input and generates the same output. TRANSIMS uses specific regions as examples in order to ensure that the technology is rooted in the real world. Until about the middle of 1997, an approximately five miles by five miles area in Dallas/Texas was used. Since then, TRANSIMS has moved to using data from Portland/Oregon; a case study for this region is planned to be completed by the end of the year 2000. In this paper the authors give short descriptions of these projects and give references to related publications.

  14. Airborne study of ozone formation over Dallas, Texas

    NASA Astrophysics Data System (ADS)

    Luria, Menachem; Valente, Ralph J.; Bairai, Solomon; Parkhurst, William J.; Tanner, Roger L.

    Twelve research fights were performed during August 2005 over the Dallas (Texas) metropolitan area. The primary objective was to estimate the relative contribution of primary emissions from large point sources, i.e., major power plants, compared with mobile sources in terms of O 3 production. The distinction between the source types was derived from concurrent measurements of SO 2 (tracer for point sources) and CO (tracer for mobile sources) relative to levels of O 3 and NO x (the O 3 precursor). The flights also examined the vertical structure of the atmosphere and its effect on the dispersion/dilution of the trace gases. During the first half of the study the O 3 levels in the Dallas area were relatively low and only during the second half were significantly elevated O 3 levels observed. For the latter period the relationship between maximum O 3 levels, the air mass chemical age and the O 3 yield are evaluated. The results also revealed that mobile sources are the main contributors to the elevated O 3 levels in the Dallas area.

  15. Dallas, police surveillance and the NHF. National Hemophilia Foundation.

    PubMed

    Dubin, C S

    1995-04-01

    In 1995, the National Hemophilia Foundation (NHF) held its annual meeting in Dallas amid ongoing controversies over AIDS and viral contamination of the U.S. blood supply. Principal topics were the class action lawsuit, delivering justice to those infected with HIV, and the legislative campaign for government compensation. The Dallas meeting was marked by controversy: the NHF failed to endorse the class action suit against blood supply producers; the NHF Board elections produced a leadership dominated by people without hemophilia and ignored persons who represented change; and a large number of police were present, authorized by the NHF, and seen by many to be a result of the NHF members' concern about potentially unruly demonstrations or possibly as a way of squashing dissent and diversity. The NHF has also discouraged those infected with HIV from taking legal action, and they have openly obstructed the pursuit of legal justice by disseminating misinformation regarding individuals' legal rights. It is felt that the NHF cannot be characterized as a consumer advocacy group and that the Dallas meeting served only to reinforce the view of NHF's role in obstructing the real empowerment of the hemophiliac community.

    1986-01-01

    On January 28, 1986, the Space Shuttle Challenger and her seven-member crew were lost when a ruptured O-ring in the right Solid Rocket Booster caused an explosion soon after launch. With the help of the U.S. Coast Guard and the U.S. Navy, search and recovery teams began retrieving pieces of the Shuttle from the Atlantic Ocean soon after the accident. Vessels brought the debris to the Trident Basin at Cape Canaveral Air Force Station, where they waited to be shipped to Kennedy Space Center for investigation. The USCG Cutter Dallas transported this fragment of exterior tiling.

  2. Characterization of the 2015 Dallas-Irving Earthquake Sequence

    NASA Astrophysics Data System (ADS)

    Quinones, L. A.; DeShon, H. R.; Scales, M. M.; Hayward, C.

    2015-12-01

    In January 2015, a pair of M3.6 earthquakes and numerous M3+ occurred along the border of Irving and Dallas, Texas, in a heavily populated portion of the Dallas-Fort Worth metropolitan area. The Irving-Dallas swarm occurs at the eastern edge of the Fort Worth (Barnett Shale) Basin, an active shale gas production area associated with induced earthquakes. However, the nearest injection well is over 10 km to the northwest and the only nearby production well shutdown in 2012. The cause of the current swarm remains unknown. A temporary seismic network was deployed in early January 2015 to acquire data to improve earthquake location estimates and better characterize the earthquake sequence. Twenty-four stations were deployed, including 13 short-term Texans and 2 USGS NetQuakes instruments. Here, we present high-resolution relative earthquake locations derived using waveform cross-correlation and double difference techniques using both P and S-waves. Waveform data shows a high degree of similarity for both phases throughout the sequence. The P-wave data exhibit power at frequencies ranging from 10 to 40 Hz, while the S-wave data typically exhibit power in the range of 2 to 10 Hz. Initial catalog locations (January-July, 2015) reveal a spatially concentrated sequence of over 480 events, ranging from M0.0 to M3.6, migrating along a NE-SW striking fault. The sequence migrated from southwest to northeast over 4 km in January, but has since migrated back to the southwest. Events occur between 4-8 km in depth, consistent with faulting in the Precambrian basement. Fault plane solutions and event locations suggest a ~70° SE dipping normal fault. Event locations within or near the granitic basement, a series of M3.3+ events, a fault area of ~16 km2, and a NE-SW trending normal fault are consistent with the characteristics of previous North Texas earthquake sequences.

  3. DFW (Dallas-Ft. Worth) microburst on August 2, 1985

    NASA Technical Reports Server (NTRS)

    Fujita, T. T.

    1986-01-01

    The features of the microburst on August 2, 1985, related to the Delta 191 accident during the approach to Runway 17L of the Dallas-Ft. Worth Airport is described. Both radar and satellite data, along with ground-based measurements, were used in determining the characteristics of the parent cloud which spawned the most complicated microburst winds ever analyzed by the author. The detailed reconstruction of the airflow and the aircraft's maneuver were made possible by a series of computer analyses of the Digital Flight Data Recorder (DFDR) readout. Both measured and computed values in color diagrams that can be evaluated readily by meteorologists, pilots, structural engineers, and other interested persons in preventing microburst-related accidents in future years are presented.

  4. Solar energy facility at North Hampton Recreation Center, Dallas, Texas

    1980-01-01

    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.

  6. C-Band Radar Imagery, Dallas-Fort Worth, Texas

    NASA Technical Reports Server (NTRS)

    2000-01-01

    The Dallas-Fort Worth metropolitan area in Texas is shown on this image collected by the C-band radar of the Shuttle Radar Topography Mission (SRTM). On this radar image, smooth areas, such as lakes, roads and airport runways appear dark. Rougher features, such as buildings and trees, appear bright. Downtown Dallas is the bright area at the center of the image, alongside the dark linear floodway of the Trinity River. Dark linear runways of two airports are also seen: Love Field near downtown Dallas in the image center, and Dallas-Fort Worth International Airport in the upper left corner. The semi-circular terminal buildings of the international airport can also be seen in the area between the runways. Several large lakes, including Lake Ray Hubbard (upper right) and Joe Pool Lake (lower left) are also seen. Images like these, along with the SRTM topographic data, will be used by urban planners to study and monitor land use, and update maps and geographic information systems for the area. This image represents just 4 seconds of data collection time by the SRTM instrument. The overall diagonal linear pattern is a data processing artifact due to the quick turn-around browse nature of this image. These artifacts will be removed with further data processing.

    This radar image was obtained by the Shuttle Radar Topography Mission as part of its mission to map the Earth's topography. The image was acquired by just one of SRTM's two antennas, and consequently does not show topographic data but only the strength of the radar signal reflected from the ground. This signal, known as radar backscatter, provides insight into the nature of the surface, including its roughness, vegetation cover, and urbanization.

    This image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR

    This report contains rainfall and runoff data collected during the 1979 water year for drainage basins of Joes Creek, Bachman Branch, Turtle Creek, Coombs Creek, Cedar Creek, White Rock Creek, Elam Creek, Fivemile Creek, Whites Branch, Prairie Creek, Tenmile Creek, Buck Creek, and South Mesquite Creek in the Dallas metropolitan area. The information will be useful in determining the extent to which progressive urbanization will affect the yield and mode of occurrence of storm runoff. Rainfall-runoff computations are presented for eight storm periods during the 1979 water year. The report for the 1979 water year completes the Dallas urban project. Hydrologic data contained in this report and in all previous reports of the Dallas and Fort Worth metropolitan areas are being used to prepare an interpretive report entitled ' Effects of urbanization on floods in the Dallas and Fort Worth, Texas, metropolitan areas, ' which will be released in 1981.

    2016-01-01

    This study assessed the psychosocial needs of Hurricane Katrina evacuees temporarily residing in Dallas, TX, after sheltering but prior to their permanent resettlement. Common trauma exposures were physical exposure to flood water, seeing corpses, witnessing death, and loss of family, friends, or home. Fewer than 10 % met symptom criteria for disaster-related posttraumatic stress disorder (PTSD). More than one-fourth met major depressive disorder (MDD) symptom criteria post-disaster but only 15 % had a new (incident) MDD episode after the disaster. Specific trauma exposures and some hurricane-related stressors contributed to risk for both Katrina-related PTSD symptom criteria and incident MDD, but other hurricane-related stressors were uniquely associated with incident MDD. Referral to mental health services was associated with meeting symptom criteria for PTSD and with incident MDD, but only about one-third of these individuals received a referral. Understanding the needs of disaster-exposed population requires assessing trauma exposures and identifying pre-disaster and post-disaster psychopathology.

    1995-06-01

    This study was sponsored by the Texas Department of Transportation (TxDOT) as part of an effort to identify a balanced transportation system for the future in the Dallas area. The system should accommodate the projected travel demand at the lowest public cost. The mission of the study is to provide an intermediate planning step between the macroscopic planning analyses performed by NCTCOG and TxDOT`s Regional Planning Office and the detailed corridor analysis performed during the design phase of a roadway improvement project. The proposed system is a set of recommendations to be considered and evaluated as part of the development of the Mobility 2010 Plan Update, the long-range transportation plan for the Dallas area. The Dallas System Planning Study was developed using a methodology that focuses on peak-hour passenger travel demand for the freeways in Dallas and surrounding counties. The study analysis differs from other planning efforts in the region by its focus on peak-hour passenger travel demands and roadway operating conditions, the use of 2015 as the design year for the facilities, and the acceptance of congestion for some alternatives to induce travel in higher-occupancy modes. The intent of the effort was to provide a system that served the travel needs with a reasonable and balanced level of congestion. The study methodology uses an iterative process to examine congestion and the consequent shift in mode so that these two factors are consistent for an alternative.

    The Iowa Stored Energy Plant Agency selected a geologic structure at Dallas Center, Iowa, for evaluation of subsurface compressed air energy storage. The site was rejected due to lower-than-expected and heterogeneous permeability of the target reservoir, lower-than-desired porosity, and small reservoir volume. In an initial feasibility study, permeability and porosity distributions of flow units for the nearby Redfield gas storage field were applied as analogue values for numerical modeling of the Dallas Center Structure. These reservoir data, coupled with an optimistic reservoir volume, produced favorable results. However, it was determined that the Dallas Center Structure cannot be simplified to four zones of high, uniform permeabilities. Updated modeling using field and core data for the site provided unfavorable results for air fill-up. This report presents Sandia National Laboratories petrologic and petrophysical analysis of the Dallas Center Structure that aids in understanding why the site was not suitable for gas storage.

  4. Heat-related deaths -- Dallas, Wichita, and Cooke counties, Texas, and United States, 1996.

    PubMed

    1997-06-13

    During July 2-8, 1996, high maximum daily temperatures in Dallas County, Texas, ranged from 101 F (38.3 C) to 106 F (41.1 C), and high maximum daily heat indexes (a measure of the effect of combined elements [e.g., heat and humidity] on the body) ranged from 105 F (40.6 C) to 112 F (44.4 C). Although guidelines for issuing heat advisories or warnings vary by geographic location and climate, the National Weather Service generally suggests issuing a heat advisory when a daytime heat index reaches > or =105 F (> or =40.6 C), and a night time minimum ambient temperature of 80 F (26.7 C) persists for at least 48 hours. In Dallas County, the criterion used by the medical examiner's (ME's) office to designate a heat wave is > or =3 consecutive days of temperatures > or =100 F (37.8 C). This report describes four cases of heat-related death in Dallas, Wichita, and Cooke counties, Texas, in 1996; summarizes risk factors for this problem; and reviews measures to prevent heat-related morbidity and mortality. The findings in this report indicate that, although a large proportion of heat-related deaths occur during the summer and during heat waves, such deaths occur year-round. PMID:9191034

  5. Impact of Urbanization on Storm Response of White Rock Creek, Dallas, Texas.

    2005-12-01

    This study documents hydrological changes resulting from urbanization of the upper sub-basin of White Rock Creek watershed in Collin and Dallas counties, Texas. The 66.4 square mile watershed was transformed from 87% rural in 1961 to 95% urban in 2002, following construction of the Dallas suburbs of Richardson, Addison, Plano and Frisco. The objective of the study was to investigate changes in the storm response of White Rock Creek in terms of peak storm flow, storm flow volume and lag time. The approach employed to compare pre- and post-urbanization hydrology was to develop average unit hydrographs for each time period and use them to generate the creek's storm flow response to a set of six hypothetical precipitation events. The results suggest that substantial hydrological changes have occurred. The average infiltration capacity of the watershed was reduced by about 60%, so that storm flow was generated at lower precipitation intensities in the post-urbanization period. Storm flow peak discharge and volume were more than doubled for a hypothetical 10-year precipitation event. Average lag time was about 45 minutes faster in the post-urbanization period. It was concluded that urbanization has significantly impacted the storm response of the creek and increased the potential for flooding. It is anticipated that similar hydrological changes will occur in other rapidly urbanizing watersheds in the Dallas-Fort Worth Metropolitan region.

    As urban development increases in metropolitan areas, the amount of impervious cover also increases and directly affects stormwater runoff volume. Techniques are needed by planning agencies to monitor urban changes and update flood maps. In this study, the six 30 meter resolution bands of Landsat TM were analyzed to determine which wavelength(s) could be used to map impervious cover in a watershed near Dallas. The resulting information was utilized in a runoff equation and compared to actual stormwater flow recorded at a U.S.G.S. gauge station. Accuracies of the image mapping and predicted runoff are presented.

    Riverscreen irrigation pumps are a relatively new design in which the pump intake floats on the river surface, pulling water in only from the bottom side and surrounded by a self-cleaning screen. The Walla Walla County Conservation District recently started replacing old pump screens with the Riverscreen and was interested in whether the screens are protective of juvenile salmonids. Pacific Northwest National Laboratory evaluated approach velocities and operations at the Riverscreen installation on the Dallas Thompson property, approximately 3 mi. north of Touchet, Washington and 300 ft north of Hofer Dam, on June 18, 2007. Evaluation of this site consisted of underwater videography and water velocity measurements. The Dallas Thompson Riverscreen was pumping approximately 930 gpm during our evaluation, which is close to the maximum pumping rate for this model. Underwater videography showed only slow movement of water-borne particulates toward the pump intake, and the screen material was clean. All water velocity measurements were taken below the pump intake opening and between 3 to 6 in. from the screen face. All approach velocities (flow toward the screen and pump) were below National Marine Fisheries Service draft guidelines for juvenile fish screens.

    Light rail transit (LRT) systems have recently been implemented in a number of urban areas throughout the United States and additional projects are in various stages of planning and development. Questions have been raised concerning the impact of these systems on ridership levels, transit operating costs, regional mobility, land use, economic development, energy, air quality, congestion levels, and other factors. The implementation of the Dallas Area Rapid Transit (DART) LRT starter line provides the opportunity to assess the impact of an LRT system in a Southwestern city in the United States. This research project was undertaken to assist with the development of a comprehensive study design for assessing the effects of the DART LRT starter line. To accomplish this objective, a review was conducted of before-and-after studies of recent LRT, heavy rail, and high-occupancy vehicle (HOV) projects. The goals and objectives of the DART system were also reviewed and existing transportation-related data collection activities in the Dallas area were examined. This information was used to develop a preliminary study design for assessing the effects of the DART LRT starter line. This report documents the review of recent before-and-after studies and presents the preliminary study design for assessing the effects of the DART LRT starter line.

    In this study, we report the first phytochemical analysis of polar fraction of Pedicularis kerneri Dalla Torre growing in Dolomites, Italy. Several iridoid glucosides were isolated, namely aucubin (1), monomelittoside (2), plantarenaloside (3), euphroside (4), mussaenosidic acid (5) and 8-epiloganic acid (6), showing a composition in accordance with previous study on this genus. The studied samples, collected from Dolomites, presented a chemotype already recognised in species from North America, characterised by euphroside (4) and aucubin (1) as main components, but the main character was the presence of monomelittoside (2) never reported in this genus. The identification of verbascoside (7), leucosceptoside A (9) and echinacoside (10) complete the systematic framing of this species since is ascertained the co-occurrence of phenylethanoid glycosides with iridoids in Lamiales species.

    The morphology and histology of the reproductive tract of males of the predator Podisus nigrispinus (Dallas) fed on different diets were studied. P. nigrispinus was fed on diets of: larvae of Alabama argillacea (Hübner), Tenebrio molitor L., Musca domestica L., and an artificial diet. The male reproductive tract, independent of diet, showed testes with intense red coloration in a compact, circular, or slightly oval structure. The vasa deferentia were similar in color to the testes and formed long filaments, which joined with the yellow-cream colored ejaculatory duct. The morphological characteristics of the male reproductive tract were similar under all diets, except for the artificial one. The histological studies demonstrated that independent of the diet the testes of P. nigrispinus were composed of four to six follicles. The testes with six follicles generally had four developed and two atrophied follicles. The morphological and histological differences of the testes of P. nigrispinus when fed with different prey are presented and discussed.

    1994-01-01

    The Quaternary Geologic Map of the Dallas 4° x 6° Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past 2+ million years, the period that includes all activities of the human species. These materials are at the surface of the Earth. They make up the ground on which we walk, the dirt in which we dig foundations, and the soil in which we grow crops. Most of our human activity is related in one way or another to these surface materials that are referred to collectively by many geologists as regolith, the mantle of fragmental and generally unconsolidated material that overlies the bedrock foundation of the continent. The maps were compiled at 1:1,000,000 scale.

    More than 100 firefighters lose their lives in the line of duty each year; many of these deaths are caused by cardiovascular events and underlying coronary heart disease. In addition, firefighters are at higher-than-normal risk of developing certain types of cancer. To improve health and fitness among its firefighters, the Dallas Fire-Rescue Department developed and implemented an annual wellness-fitness program in 2008. The program detected and addressed medical issues including coronary disease, hypertension, high triglyceride levels, high cholesterol, high blood glucose levels, and hematuria. Prostate, thyroid, breast, kidney, and bladder cancers were also detected. By identifying these issues, engaging the firefighters' personal physicians, and recommending individualized treatment plans, this program may have extended lives and improved the quality of life for the firefighters.

    2015-12-01

    Southernmost South America is unique in its position immediately north of the present-day Antarctic Convergence, making it ideally suited for the evaluation of Antarctic influences on terrestrial paleoclimate. Here we present a glacial geomorphic interpretation of the paleoglacial history of Glaciar Dalla Vedova in Bahía Blanca, Cordillera Darwin, Chile (53°S). This interpretation is further constrained by radiocarbon dating, cosmogenic dating, dendrochronology, and historical photogrammetry. Preliminary field work suggests that Holocene glacier fluctuations have been constrained to within 3 km of the present glacier boundary, punctuated by rapid recent glacier retreat over the past century. By comparing the observed chronology with the record contained further north in Patagonia, we will evaluate possible mechanisms of regional climate variability over the Holocene across southernmost South America.

    The dual-polarization X-band radar network developed by the U.S. National Science Foundation Engineering Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) has shown great advantages for observing and prediction of hazardous weather events in the lower atmosphere (1-3 km above ground level). The network is operating though a scanning methodology called DCAS, distributed collaborative adaptive sensing, which is designed to focus on particular interesting regions of the atmosphere and disseminate information for decision-making to multiple end-users, such as emergency managers and policy analysts. Since spring 2012, CASA and the North Central Texas Council of Governments (NCTCOG) have embarked the development of Dallas Fort Worth (DFW) urban remote sensing network, including 8-node of dual-polarization X-band radars, in the populous DFW Metroplex (pop. 6.3 million in 2010). The main goal of CASA DFW urban demonstration network is to protect the safety and prosperity of humans and ecosystems through research activities that include: 1) to demonstrate the DCAS operation paradigm developed by CASA; 2) to create high-resolution, three-dimensional mapping of the meteorological conditions; 3) to help the local emergency managers issue impacts-based warnings and forecasts for severe wind, tornado, hail, and flash flood hazards. The products of this radar network will include single and multi-radar data, vector wind retrieval, quantitative precipitation estimation and nowcasting, and numerical weather predictions. In addition, the high spatial and temporal resolution rainfall products from CASA can serve as a reliable data input for distributed hydrological models in urban area. This paper presents the information and communication link between radars, rainfall product generation, hydrologic model link and end user community in the Dallas Fort Worth Urban Network.

    2012-01-01

    Introduction To investigate relationships between ambient temperatures and violent crimes to determine whether those relationships are consistent across different crime categories and whether they are best described as increasing linear functions, or as curvilinear functions that decrease beyond some temperature threshold. A secondary objective was to consider the implications of the observed relationships for injuries and deaths from violent crimes in the context of a warming climate. To address these questions, we examined the relationship between daily ambient temperatures and daily incidents of violent crime in Dallas, Texas from 1993–1999. Methods We analyzed the relationships between daily fluctuations in ambient temperature, other meteorological and temporal variables, and rates of daily violent crime using time series piece-wise regression and plots of daily data. Violent crimes, including aggravated assault, homicide, and sexual assault, were analyzed. Results We found that daily mean ambient temperature is related in a curvilinear fashion to daily rates of violent crime with a positive and increasing relationship between temperature and aggravated crime that moderates beyond temperatures of 80°F and then turns negative beyond 90°F. Conclusion While some have characterized the relationship between temperature and violent crime as a continually increasing linear function, leaving open the possibility that aggravated crime will increase in a warmer climate, we conclude that the relationship in Dallas is not linear, but moderates and turns negative at high ambient temperatures. We posit that higher temperatures may encourage people to seek shelter in cooler indoor spaces, and that street crime and other crimes of opportunity are subsequently decreased. This finding suggests that the higher ambient temperatures expected with climate change may result in marginal shifts in violent crime in the short term, but are not likely to be accompanied by markedly

  12. Floods on White Rock Creek above White Rock Lake at Dallas, Texas

    Gilbert, Clarence R.

    1963-01-01

    The White Rock Creek watershed within the city limits of Dallas , Texas, presents problems not unique in the rapid residential and industrial development encountered by many cities throughout the United States. The advantages of full development of the existing area within a city before expanding city boundaries, are related to both economics and civic pride. The expansion of city boundaries usually results in higher per capital costs for the operation of city governments. Certainly no responsible city official would oppose reasonable development of watersheds and flood plains and thus sacrifice an increase in tax revenue. Within the words "reasonable development" lies the problem faced by these officials. They are aware that the natural function of a stream channel, and its associated flood plain is to carry away excess water in time of flood. They are also aware that failure to recognize this has often led to haphazard development on flood plains with a consequent increase in flood damages. In the absence of factual data defining the risk involved in occupying flood plains, stringent corrective and preventative measures must be taken to regulate man's activities on flood plains to a point beyond normal precaution. Flood-flow characteristics in the reach of White Rock Creek that lies between the northern city boundary of Dallas and Northwest Highway (Loop 12) at the upper end of White Rock Lake, are presented in this report. Hydrologic data shown include history and magnitude of floods, flood profiles, outlines of areas inundated by three floods, and estimates of mean velocities of flow at selected points. Approximate areas inundated by floods of April 1942 and July 1962 along White Rock Creek and by the flood of October 1962 along Cottonwood Creek, Floyd Branch, and Jackson Branch, are delineated on maps. Greater floods have undoubtedly occurred in the past but no attempt is made to show their probable overflow limits because basic data on such floods could not

    Between 31 October 2008 and 16 May 2009, the USGS National Earthquake Information Center (NEIC) reported 14 earthquakes with magnitudes between 2.5 and 3.3 and epicenters between Dallas and Fort Worth (DFW), Texas. Local residents felt nine of these earthquakes, and news stories expressed locals' concern and speculation that the earthquakes might be related to recent natural gas drilling in the Barnett Shale. We report on analysis of data collected by continuously operating regional stations and by a five-station temporary local network operated in the DFW area between 9 November 2008 and 2 January 2009. We also discuss preliminary results from temporary networks operated since June 2009 near DFW and Cleburne, TX. Both portable deployments were supported by PASSCAL. Among the observations at regional distances, the station WMOK (Wichita Mountain, Oklahoma; Δ = 2.36°) has clear recordings of DFW quakes and initial data processing showed that waveforms from the reported DFW quakes were all highly correlated. Cross correlation of the continuous signal at WMOK with known DFW quake signals found no DFW quakes occurring prior to 30 October 2008, and then ~180 similar events occurring between 30 October and 17 May 2009. These earthquakes had magnitudes of 1.5 and greater, and most occurred in four time periods; 100 occurred from 30 Oct to 1 Nov; 11 on 20 Nov; 18 on 26 December, and 28 on 15-17 May. Eleven of these earthquakes were exceptionally well recorded by the 2008 temporary network, allowing us to determine accurate relative locations using velocities measured in a nearby deep well. Our preferred hypocentral locations have focal depths of ~4.5 km and lie along a 1.1 km SW-NE line on the DFW airport property, south of the main terminal area. The mean epicenter determined for these 11 events is less than 0.5 km from a 4.2 km deep saltwater disposal (SWD) drilled to dispose of brines associated with natural gas production. Injection of brines in this well commenced

    Objective To ascertain the cost-effectiveness and benefit-cost ratios of 2 public health campaigns conducted in Dallas and Houston in 1998–2000 for “catch-up” hepatitis B vaccination of Vietnamese-Americans born 1984–1993. Design Program evaluation. Setting Houston and Dallas, Texas. Participants A total of 14 349 Vietnamese-American children and adolescents. Interventions Media-led information and education campaign in Houston, and community mobilization strategy in Dallas. Outcomes were compared with a control site: Washington, DC. Main outcome measures Receipt of 1, 2, or 3 doses of hepatitis B vaccine before and after the interventions, costs of interventions, cost-effectiveness ratios for intermediate outcomes, intervention cost per discounted year of life saved, and benefit-cost ratio of the interventions. Results The number of children who completed the series of 3 hepatitis B vaccine doses increased by 1176 at a total cost of $313 904 for media intervention, and by 390 and at $169 561 for community mobilization. Costs per child receiving any dose, per dose, and per completed series were $363, $101, and $267 for media intervention and $387, $136, and $434 for community mobilization, respectively. For media intervention, the intervention cost per discounted year of life saved was $9954 and 131 years of life were saved; for community mobilization, estimates were $11 759 and 60 years of life. The benefit-cost ratio was 5.26:1 for media intervention and 4.47:1 for community mobilization. Conclusion Although the increases in the number of children who completed series of 3 doses were modest for both the Houston and Dallas areas, both media education and, to a lesser degree, community mobilization interventions proved cost-effective and cost-beneficial.

    2015-12-01

    The Dallas-Fort Worth (DFW) urban radar network consists of a combination of high resolution X band radars and a standard National Weather Service (NWS) Next-Generation Radar (NEXRAD) system operating at S band frequency. High spatiotemporal-resolution quantitative precipitation estimation (QPE) is one of the important applications of such a network. This paper presents a real-time QPE system developed by the Collaborative Adaptive Sensing of the Atmosphere (CASA) Engineering Research Center for the DFW urban region using both the high resolution X band radar network and the NWS S band radar observations. The specific dual-polarization radar rainfall algorithms at different frequencies (i.e., S- and X-band) and the fusion methodology combining observations at different temporal resolution are described. Radar and rain gauge observations from four rainfall events in 2013 that are characterized by different meteorological phenomena are used to compare the rainfall estimation products of the CASA DFW QPE system to conventional radar products from the national radar network provided by NWS. This high-resolution QPE system is used for urban flash flood mitigations when coupled with hydrological models.

    The Global Precipitation Measurement (GPM) Core Observatory was launched on February 27, 2014. The two advanced instruments onboard GPM, namely, Dual-frequency Precipitation Radar (DPR) and GPM Microwave Imager (GMI), can provide measurement of rainfall, snowfall, ice and other precipitation over most of the globe. As an integral part of all satellite precipitation missions, ground validation helps to quantify precipitation measurement uncertainty and provide insight into the physical and statistical basis of retrieval algorithms. Among various validation instruments, ground-based dual-polarization radar (at S, C and X band frequencies) has been shown to be a powerful tool to estimate surface rainfall. This paper will present the concept of level one validation of GPM using high resolution precipitation observations from DFW network. The area of interest in this study is Dallas-Fort Worth (DFW) Metroplex, which hosts a network of six high-resolution dual-polarization X-band radars operated by the center for Collaborative Adaptive Sensing of the Atmosphere (CASA) and the NWS WSR-88DP radar (i.e., KFWS radar). The DFW network QPE product has been shown to be of excellent quality, in terms of accuracy as well as space time resolution (Chen and Chandrasekar, Journal of Hydrology, May (2015)). Detailed comparisons will be conducted between GPM based rainfall estimates and ground radar observations collected during the GPM satellite overpasses over DFW region. Dual-polarization based raindrop size distribution (DSD) retrieval, quantitative precipitation estimation (QPE), and hydrometeor classifications will be presented in detail.

    The orsillid genus Nysius Dallas is a complex and large genus with more than 100 described species worldwide, and includes many species of agricultural importance, one such example is N. simulans (Stål) from Argentina. Three species of Nysius are found in this country: N. simulans (Stål), N. irroratus (Spinola) and N. puberulus Berg. The material available for the present study, consisting of over 610 specimens, was collected by sweep-net, G-Vac and light trap in the provinces of Chubut (42° to 46°S; 63.5° to 72° W), La Pampa (35º to 39º south; 63º to 68º West), Neuquén (36° to 41° S; 68° to 71°W) and Río Negro (37° to 42°S; 62° to 71°W), in the central region of Argentina, during the years 2010-2014. Although the species N. simulans is frequently recorded as a pest of soybean crop, there exist no detailed description but only a brief general diagnosis. In the present contribution, therefore, we provide a detailed redescription as well as an updated distribution of N. simulans and N. irroratus, and a key for species of genus Nysius present in Argentina.

    1993-01-15

    Safer sex practices intended to reduce the risk for human immunodeficiency virus (HIV) infection have been vigorously promoted among men who are homosexual or bisexual (i.e., men who have sex with men). Such efforts have emphasized personal responsibility and protection of partners, and many of these men appear to have adopted risk-reducing behaviors (1). However, it is unknown whether these safer sex practices and norms have been adopted by men who have sex with men but conceal their sexual orientations or do not self-identify as homosexual or bisexual (2-7). To characterize the relation between the adoption of safer sex practices among men who have sex with men and sexual self-identity, as well as HIV information-seeking, exposure to the homosexual or bisexual community culture, and comfort in disclosing sexual identity, the Dallas County (Texas) Health Department (DCHD) conducted a survey among men who have sex with men. This report summarizes survey findings for men who reported having had sex with men and who visited DCHD clinics for anonymous HIV counseling and testing from January through June 1991.

    Limited visibility is the single most critical factor affecting the safety and capacity of worldwide aviation operations. Synthetic Vision Systems (SVS) technology can solve this visibility problem with a visibility solution. These displays employ computer-generated terrain imagery to present 3D, perspective out-the-window scenes with sufficient information and realism to enable operations equivalent to those of a bright, clear day, regardless of weather conditions. To introduce SVS display technology into as many existing aircraft as possible, a retrofit approach was defined that employs existing HDD display capabilities for glass cockpits and HUD capabilities for the other aircraft. This retrofit approach was evaluated for typical nighttime airline operations at a major international airport. Overall, 6 evaluation pilots performed 75 research approaches, accumulating 18 hours flight time evaluating SVS display concepts that used the NASA LaRC's Boeing B-757-200 aircraft at Dallas/Fort Worth International Airport. Results from this flight test establish the SVS retrofit concept, regardless of display size, as viable for tested conditions. Future assessments need to extend evaluation of the approach to operations in an appropriate, terrain-challenged environment with daytime test conditions.

    The occurrence, trends, and sources of numerous inorganic and organic contaminants were evaluated in Mountain Creek Lake, a reservoir in Dallas, Texas. The study, done in cooperation with the Southern Division Naval Facilities Engineering Command, was prompted by the Navy?s concern for potential off-site migration of contaminants from two facilities on the shore of Mountain Creek Lake, the Naval Air Station Dallas and the Naval Weapons Industrial Reserve Plant. Sampling of stormwater (including suspended sediment), lake water, bottom sediment (including streambed sediment), and fish was primarily in Mountain Creek Lake but also was in stormwater outfalls from the Navy facilities, nearby urban streams, and small streams draining the Air Station. Volatile organic compounds, predominantly solvents from the Reserve Plant and fuel-related compounds from the Air Station, were detected in stormwater from both Navy facilities. Fuel-related compounds also were detected in Mountain Creek Lake at two locations, one near the Air Station inlet where stormwater from a part of the Air Station enters the lake and one at the center of the lake. Concentrations of volatile organic compounds at the two lake sites were small, all less than 5 micrograms per liter. Elevated concentrations of cadmium, chromium, copper, lead, mercury, nickel, silver, and zinc, from 2 to 4 times concentrations at background sites and urban reference sites, were detected in surficial bottom sediments in Cottonwood Bay, near stormwater outfalls from the Reserve Plant. Elevated concentrations of polycyclic aromatic hydrocarbons and polychlorinated biphenyls, compared to background and urban reference sites, were detected in surficial sediments in Cottonwood Bay. Elevated concentrations of polycyclic aromatic hydrocarbons, indicative of urban sources, also were detected in Cottonwood Creek, which drains an urbanized area apart from the Navy facilities. Elevated concentrations of polychlorinated biphenyls were

    During wintertime, haze episodes occur in the Dallas-Ft. Worth (DFW) urban area. Such episodes are characterized by substantial light scattering by particles and relatively low absorption, leading to so-called "white haze." The objective of this work was to assess whether reductions in the emissions of SO2 from specific coal-fired power plants located over 100 km from DFW could lead to a discernible change in the DFW white haze. To that end, the transport, dispersion, deposition, and chemistry of the plume of a major power plant were simulated using a reactive plume model (ROME). The realism of the plume model simulations was tested by comparing model calculations of plume concentrations with aircraft data of SF6 tracer concentrations and ozone concentrations. A second-order closure dispersion algorithm was shown to perform better than a first-order closure algorithm and the empirical Pasquill-Gifford-Turner algorithm. For plume impact assessment, three actual scenarios were simulated, two with clear-sky conditions and one with the presence of fog prior to the haze. The largest amount of sulfate formation was obtained for the fog episode. Therefore, a hypothetical scenario was constructed using the meteorological conditions of the fog episode with input data values adjusted to be more conducive to sulfate formation. The results of the simulations suggest that reductions in the power plant emissions lead to less than proportional reductions in sulfate concentrations in DFW for the fog scenario. Calculations of the associated effects on light scattering using Mie theory suggest that reduction in total (plume + ambient) light extinction of less than 13% would be obtained with a 44% reduction in emissions of SO2 from the modeled power plant.

    Concentrations of trichloroethene in ground water at the Naval Weapons Industrial Reserve Plant in Dallas, Texas, indicate three source areas of chlorinated solvents?building 1, building 6, and an off-site source west of the facility. The presence of daughter products of reductive dechlorination of trichloroethene, which were not used at the facility, south and southwest of the source areas are evidence that reductive dechlorination is occurring. In places south of the source areas, dissolved oxygen concentrations indicated that reduction of oxygen could be the dominant process, particularly south of building 6; but elevated dissolved oxygen concentrations south of building 6 might be caused by a leaking water or sewer pipe. The nitrite data indicate that denitrification is occurring in places; however, dissolved hydrogen concentrations indicate that iron reduction is the dominant process south of building 6. The distributions of ferrous iron indicate that iron reduction is occurring in places south-southwest of buildings 6 and 1; dissolved hydrogen concentrations generally support the interpretation that iron reduction is the dominant process in those places. The generally low concentrations of sulfide indicate that sulfate reduction is not a key process in most sampled areas, an interpretation that is supported by dissolved hydrogen concentrations. Ferrous iron and dissolved hydrogen concentrations indicate that ferric iron reduction is the primary oxidation-reduction process. Application of mean first-order decay rates in iron-reducing conditions for trichloroethene, dichloroethene, and vinyl chloride yielded half-lives for those solvents of 231, 347, and 2.67 days, respectively. Decay rates, and thus half-lives, at the facility are expected to be similar to those computed. A weighted scoring method to indicate sites where reductive dechlorination might be likely to occur indicated strong evidence for anaerobic biodegradation of chlorinated solvents at six sites

    Diabetes mellitus (DM) has been termed a "coronary disease equivalent", yet data suggest that only those DM subjects with metabolic syndrome (MetS) are at increased coronary risk. Using data from the Dallas Heart Study, a large, probability-based population study, we assessed the individual and joint associations between MetS, DM and atherosclerosis, defined as coronary artery calcium (CAC) detected by electron-beam computerised tomography (EBCT) and abdominal aortic plaque (AAP) detected by magnetic resonance imaging. Among 2,735 participants, the median age was 44 years; 1,863 (68%) were non-white; 1,509 (55%) were women; 697 (25.5%) had MetS without DM; 53 (1.9%) had DM without MetS; and 246 (9.0%) had both DM and MetS. The prevalence of CAC increased from those with neither MetS nor DM (16.6%) to MetS only (24.0%) to DM only (30.2%) to both MetS and DM (44.7%) (ptrend <0.0001). The prevalence of CAC was higher in those with both DM and MetS versus either alone (p<0.0001). After adjustment, MetS and DM were each independently associated with CAC (odds ratio [OR] 1.4, 95% confidence intervals [CI] 1.1-1.8; OR 1.8, 95% CI 1.3-2.5, respectively). Compared with the group without DM or MetS, those with both MetS and DM had the most CAC (adjusted OR 2.3; 95% CI 1.6-3.2). All analyses of AAP yielded qualitatively similar results. In conclusion, both MetS and DM are independently associated with an increased prevalence of atherosclerosis, with the highest observed prevalence in subjects with both DM and MetS. PMID:18537096

    Previous studies have demonstrated ethnic/racial differences in cardiorespiratory fitness (CRF). However, the relative contributions of body mass index (BMI), lifestyle behaviors, socioeconomic status (SES), cardiovascular (CV) risk factors, and cardiac function to these differences in CRF are unclear. In this study, we included 2,617 Dallas Heart Study participants (58.6% women, 48.6% black; 15.7% Hispanic) without CV disease who underwent estimation of CRF using a submaximal exercise test. We constructed multivariable-adjusted linear regression models to determine the association between race/ethnicity and CRF, which was defined as peak oxygen uptake (ml/kg/min). Black participants had the lowest CRF (blacks: 26.3 ± 10.2; whites: 29.0 ± 9.8; Hispanics: 29.1 ± 10.0 ml/kg/min). In multivariate analysis, both black and Hispanic participants had lower CRF after adjustment for age and gender (blacks: Std β = -0.15; p value ≤0.0001, Hispanics: Std β = -0.05, p value = 0.01; ref group: whites). However, this association was considerably attenuated for black (Std β = -0.04, p value = 0.03) and no longer significant for Hispanic ethnicity (p value = 0.56) after additional adjustment for BMI, lifestyle factors, SES, and CV risk factors. Additional adjustment for stroke volume did not substantially change the association between black race/ethnicity and CRF (Std β = -0.06, p value = 0.01). In conclusion, BMI, lifestyle, SES, and traditional risk factor burden are important determinants of ethnicity-based differences in CRF. PMID:27349903

    Sodium and chloride in surface water are typically related to urbanization and population density and can have a significant impact on drinking water sources and the subsequent salinity of aquatic ecosystems. While the majority of research has focused on the impact of deicing salts on urban surface waters in colder climates, the effect of urbanization on sodium and chloride concentrations has been found to occur in warmer climates. This study investigated long-term exports of sodium and chloride from watersheds with increasing urbanization in the humid subtropical Dallas-Fort Worth region. We compared exports to characteristics of urbanization: urban land cover, impervious surface area, and calculated contributions from wastewater discharges. Long-term data (1980-2008) were obtained from five USGS gages located in and around the cities. Exports were calculated by regression analysis between concentrations and discharge and normalized for time and the watershed area. Grab samples were collected from June 2009 to May 2010 and sodium and chloride concentrations quantified. Our results show a strong positive relationship between the mean annual sodium and chloride exports from each watershed and the percent urban land cover and impervious surface area. Long-term increases in sodium and chloride fluxes were found for the three watersheds with the highest percentage of urban land cover. The single largest contributor was wastewater effluent that was estimated to contribute approximately half of the total loads in the three urbanized watersheds. Atmospheric deposition and deicing salts accounted for small amounts of the total export for urbanized watersheds. The source of the remaining salt load is still unknown and may be a combination of non-point sources. Estimates of urban salt exports were similar to estimates from northern watersheds affected by deicing salts.

    Objectives The objective of this article is to extend our previous studies of persistent organic pollutant (POP) contamination of U.S. food by measuring perfluorinated compounds (PFCs), organochlorine pesticides, and polychlorinated biphenyls (PCBs) in composite food samples. This study is part of a larger study reported in two articles, the other of which reports levels of polybrominated diphenyl ethers and hexabromocyclododecane brominated flame retardants in these composite foods [Schecter et al. 2010. Polybrominated diphenyl ethers (PBDEs) and hexabromocyclodecane (HBCD) in composite U.S. food samples, Environ Health Perspect 118:357–362]. Methods In this study we measured concentrations of 32 organochlorine pesticides, 7 PCBs, and 11 PFCs in composite samples of 31 different types of food (310 individual food samples) purchased from supermarkets in Dallas, Texas (USA), in 2009. Dietary intake of these chemicals was calculated for an average American. Results Contamination varied greatly among chemical and food types. The highest level of pesticide contamination was from the dichlorodiphenyltrichloroethane (DDT) metabolite p,p′- dichlorodiphenyldichloroethylene, which ranged from 0.028 ng/g wet weight (ww) in whole milk yogurt to 2.3 ng/g ww in catfish fillets. We found PCB congeners (28, 52, 101, 118, 138, 153, and 180) primarily in fish, with highest levels in salmon (PCB-153, 1.2 ng/g ww; PCB-138, 0.93 ng/g ww). For PFCs, we detected perfluorooctanoic acid (PFOA) in 17 of 31 samples, ranging from 0.07 ng/g in potatoes to 1.80 ng/g in olive oil. In terms of dietary intake, DDT and DDT metabolites, endosulfans, aldrin, PCBs, and PFOA were consumed at the highest levels. Conclusion Despite product bans, we found POPs in U.S. food, and mixtures of these chemicals are consumed by the American public at varying levels. This suggests the need to expand testing of food for chemical contaminants. PMID:20146964

    Purpose Leptin dysregulation has been postulated to affect cancer risk through its effects on obesity and inflammation. Epidemiological data evaluating this relationship are conflicting and studies in non-white cohorts is lacking. Therefore, we examined the association of leptin with the risk of incident cancer in the multiethnic Dallas Heart Study (DHS). Methods Participants enrolled in the DHS without prevalent cancer and with baseline leptin measurements were included. Incident cancer cases were identified through a systematic linkage of the DHS and the Texas Cancer Registry. Leptin was evaluated both as a continuous variable and in sex-specific quartiles. Multivariable Cox proportional hazards modeling was performed to examine the association between leptin levels with incident cancer after adjusting for age, sex, race, smoking status, alcohol use, family history of malignancy, body mass index (BMI), diabetes mellitus and C-reactive protein. Results Among 2,919 participants (median age 44 years; 54% women; 70% nonwhite; median BMI 29.4 kg/m2), 190 (6.5%) developed cancer after median follow- up of 12 years. Median leptin levels were 12.9 (interquartile range [IQR] 5.8–29.5) ng/ml in the incident cancer group vs. 12.3 (IQR 5.4–26.4) ng/ml those without an incident cancer (p = 0.34). Leptin was not associated with cancer incidence in multivariable analysis (unit standard deviation increase in log-transformed leptin, hazard ratio 0.95; 95% confidence interval, 0.77–1.16; p = 0.60). No association was observed in analyses stratified by sex, race/ethnicity, diabetes, or obesity status. Conclusions In this study of a predominantly minority population, no association between premorbid leptin levels and cancer incidence was demonstrated. Despite preclinical rationale and positive findings in other studies, this association may not replicate across all racial/ethnic populations. PMID:27636369

    The Dallas Freeway/High-Occupany Vehicle Lane System Planning Study is a joint project in cooperation with the Texas Department of Transportation (TxDOT), Dallas Area Rapid Transit (DART), the North Central Texas Council of Governments (NCTCOG), and the Texas Transportation Institute (TTI). The intent of this effort is to assist in the development of an area-wide freeway/HOV system that recognizes implementation constraints (right-of-way and construction costs) and provides reasonable peak-hour operating conditions on all freeway facilities, while incorporating the long-range plans developed by TxDOT, DART, and NCTCOG. The proposed system is a set of recommendations to be considered and evaluated as part of the development of the NCTCOG Mobility 2010 Plan Update, the long-range transportation plan for the Dallas area. HOV facilities are a significant part of the recommended system in the Dallas System Planning Study, and their implementation is important to the successful operation of the Dallas area transportation system in the future. The report, therefore, focuses on the recommended HOV improvements from the methodology.

    Limited capital investment for major transportation improvements and growth in metropolitan areas require the most efficient use of the existing transportation system. One means to achieve this is high-occupancy vehicle (HOV) lanes. While an extensive system of permanent HOV lanes is planned for the Dallas-Fort Worth urbanized area, the Texas Department of Transportation (TxDOT) and Dallas Area Rapid Transit (DART) have pursued and continue short-term or interim HOV lane projects that would enhance public transportation and overall mobility. There are currently 57 km (35.4 mi) of interim HOV lanes operational in the Dallas area, including a barrier-separated contraflow lane on I-30 (East R.L. Thornton Freeway) and buffer-separated concurrent flow HOV lanes on I-35E North (Stemmons Freeway) and I-635 (Lyndon B. Johnson Freeway). The objective of this research is to investigate the operational effectiveness of the new concurrent flow HOV lanes in the Dallas area, as well as to assess the effectiveness of concurrent flow (buffer-separated) versus contraflow (barrier-separated) HOV lanes. Issues such as person movement, carpool formation, travel time savings, violation rates, and project cost effectiveness are addressed. By understanding the operational performance and issues of both concurrent flow (buffer-separated) HOV lanes and contraflow (barrier-separated) HOV lanes, recommendations can be made on suggested HOV lane polices, including the type of permanent HOV lanes to be implemented in the Dallas area.

    Previous atmospheric modeling efforts that concentrated on the Los Angeles Basin suggested beneficial and significant air quality impacts from cool cities strategies. This paper discusses an extension of similar modeling efforts to three regions, Atlanta GA, Dallas - Ft. Worth TX, and Nashville TN, that experience smog and air quality problems. According to the older ozone air quality standard (120 ppb), these regions were classified as serious, moderate, and marginal, respectively, but may be out of compliance with respect to the newer, 80-ppb/8-hours standard. Results from this exploratory modeling work suggest a range of possible impacts on meteorological and air quality conditions. For example, peak ozone concentrations during each region's respective episode could be decreased by 1-6 ppb (conservative and optimistic scenarios, respectively) in Nashville, 5-15 ppb in Dallas - Fort Worth, and 5-12 ppb in Atlanta following implementation of cool cities. The reductions are generally smaller than those obtained from simulating the Los Angeles Basin but are still significant. In all regions, the simulations suggest, the net, domain-wide effects of cool cities are reductions in ozone mass and improvements in air quality. In Atlanta, Nashville, and Dallas, urban areas benefiting from reduced smog reach up to 8460, 7350, and 12870 km{sup 2} in area, respectively. Results presented in this paper should be taken as exploratory and preliminary. These will most likely change during a more comprehensive modeling study to be started soon with the support of the US Environmental Protection Agency. The main purpose of the present project was to obtain the initial data (emission inventories) for these regions, simulate meteorological conditions, and perform preliminary sensitivity analysis. In the future, additional regions will be simulated to assess the potential of cool cities in improving urban air quality.

    Since spring 2012, the U.S. National Science Foundation Engineering Research Center (NSF-ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA) has been transformed from a research to operational demonstration emphasis, and has started the development of Dallas-Fort worth (DFW) urban remote sensing network. The main goal of this network is to demonstrate the operational feasibility of the dense radar network in a metropolitan environment. The DFW network consists of 8 dual-polarization X-band weather radars covering the greater DFW metropolitan area, the 4th largest Metroplex in the nation. The major issued to be addressed include urban flash flood mitigation, severe weather warning and demonstration of network-of-network concept. It is also expected to be an ideal development platform for multi-Doppler wind retrieval, quantitative precipitation estimation (QPE), quantitative precipitation forecast (QPF), and accurate hydrologic response. The real-time weather information will then be disseminated to public and private stakeholders for decision-making and evaluation as severe weather events occur in the Metroplex. In addition, multi-sensor products will be generated as well from combining the existing remote sensors such as KFWS radar (a WSR-88DP radar), TDWR, and local rainfall gauges. This paper will first present a brief overview of the current development of CASA DFW urban radar network. Then, the Kdp-based QPE methodology for CASA X-band radars will be described and evaluated in depth. The composite rainfall products produced by combining the S-band WSR-88DP and X-band radar observations will also be presented. To demonstrate and evaluate the QPE products, local rainfall gauges are used for cross comparison between the radar rainfall measurements and gauge observations. In addition, the prototype flash flood forecasting system under development for the City of Fort Worth will also be described in this paper, which utilizes the high spatial and

    Our aim was to investigate the associations of regional fat distribution with home and office blood pressure (BP) levels and variability. Participants in the Dallas Heart Study, a multiethnic cohort, underwent 5 BP measurements on 3 occasions during 5 months (2 in home and 1 in office) and quantification of visceral adipose tissue, abdominal subcutaneous adipose tissue, and liver fat by magnetic resonance imaging, and lower body subcutaneous fat by dual x-ray absorptiometry. The relation of regional adiposity with short-term (within-visit) and long-term (overall visits) mean BP and average real variability was assessed with multivariable linear regression. We have included 2595 participants with a mean age of 44 years (54% women; 48% black), and mean body mass index was 29 kg/m(2) Mean systolic BP/diastolic BP was 127/79 mm Hg and average real variability systolic BP was 9.8 mm Hg during 3 visits. In multivariable-adjusted models, higher amount of visceral adipose tissue was associated with higher short-term (both home and office) and long-term mean systolic BP (β[SE]: 1.9[0.5], 2.7[0.5], and 2.1[0.5], respectively; all P<0.001) and with lower long-term average real variability systolic BP (β[SE]: -0.5[0.2]; P<0.05). In contrast, lower body fat was associated with lower short-term home and long-term mean BP (β[SE]: -0.30[0.13] and -0.24[0.1], respectively; both P<0.05). Neither subcutaneous adipose tissue or liver fat was associated with BP levels or variability. In conclusion, excess visceral fat was associated with persistently higher short- and long-term mean BP levels and with lower long-term BP variability, whereas lower body fat was associated with lower short- and long-term mean BP. Persistently elevated BP, coupled with lower variability, may partially explain increased risk for cardiac hypertrophy and failure related to visceral adiposity.

    During January 1994, feces from a captive juvenile Galápagos tortoise, Chelonoidis sp., from the Dallas Zoo, Dallas County, Texas was examined for coccidia. The tortoise was found to harbor an eimerian which is described as new. Sporulated oocysts of Eimeria iversoni n. sp. were ovoidal with a smooth, single-layered wall (∼ 0.5-0.8) that measured (L × W) 13.5 × 10.3 μm, with a length/width (L/W) ratio of 1.3; micropyle, oocyst residuum, and polar granule(s) were all absent; 2 conical projections were present on 1 end of oocyst and measured 1.0-1.5. Sporocysts were elongate-ellipsoidal and measured 8.3 × 4.5 μm, with L/W of 1.8; a Stieda body (∼ 0.5 high) was present, but substieda and parastieda bodies were absent; a sporocyst residuum was composed of 2-5 granules in a compact mass between sporozoites; sporozoites were banana-shaped and measured 9.5 × 2.5 in situ, with an ellipsoidal posterior refractile body and a spheroidal anterior refractile body. This is only the second time an eimerian has been reported from Galápagos tortoises.

  16. Effect of Surface Traffic Count on Taxi Time at Dallas-Fort Worth (DFW) International Airport

    2008-01-01

    As the amount of air traffic increases over the years, most airports simply do not have the means of expanding to handle the intensified traffic on the surface that will ensue. Precise surveillance equipment and automation concepts, as well as advanced surface traffic algorithms are being developed to improve airport efficiency. These surface algorithms require inputs unique to each airport to ensure maximum efficiency, and minimal taxi delay. This study analyzes surface traffic at Dallas-Fort Worth International Airport (DFW) to determine the effect of the number of aircraft on the surface and the amount of stop and go situations they experience to the amount of additional taxi time encountered. If the surface capacity of an airport is known, minimal delay can be accomplished by limiting the number of taxiing aircraft to that capacity. This concept is related to highways, where traffic flow drastically decreases as more cars occupy the road. An attempt to minimize this effect on highways is seen with the use of metering lights at freeway on-ramps. Since the surface traffic at airports is highly regulated, and aircraft are less mobile on the ground, limiting the surface count to a certain number can greatly reduce the amount of additional taxi time encountered, as well as reduce hazardous emissions. This study will also find the regions of an airport that encounter the most additional taxi time when the number of aircraft in that area is increased. This could help surface traffic algorithms avoid congesting that area, or re-route aircraft to different runways when that area reaches its capacity. The relationship between the amount of stop and go situations an aircraft encounters and their effect on the taxi time of that aircraft will also be investigated. This will help to determine the effect of holding an aircraft on the taxiway as opposed to re-routing it. The lesser of the two should be used when developing surface traffic algorithms to further minimize the

    The Dallas Pain Questionnaire (DPQ) was developed to assess the amount of chronic spinal pain that affects four aspects (daily and work-leisure activities, anxiety-depression, and social interest) of the patients' lives. Results of the DPQ's statistical properties suggest that the DPQ is an externally reliable instrument as well as internally consistent. Two factors emerged from factor structure analysis. Factor 1 represents functional activities and Factor 2 represents emotional capacities. A correlation analysis suggests the concurrent validity of the psychological functional factors of the DPQ. A t test demonstrated that chronic pain patients have significantly higher DPQ scores than normals. Because these findings support its statistical properties, the DPQ appears to have utility for clinical and research purposes. The findings, limitations, and implications of this study are detailed, as are suggestions for future research.

    Public awareness of soils contamination has increased in recent years due in part to the notoriety associated with the indiscriminate release, packaging, transporting and disposal of hazardous materials. In 1980, and again in 1982, the U.S. Environmental Protection Agency (EPA) was responsible for designing, implementing and conducting environmental monitoring programs at Love Canal in Niagara Falls, New York, and in Dallas, Texas, that dealt with suspected contaminated soils. Both of these monitoring programs were conducted over a relatively short time with the collection and analysis of over 4000 soil samples. The methods employed by the Environmental Protection Agency for providing soil data that was scientifically valid and of defensible quality for each of these monitoring programs are presented. Also, methods for identifying data bias, its precision and its uncertainty are identified. PMID:24258929

    NASA/Langley Research Center collaborated with the Federal Aviation Administration (FAA) to test a Runway Incursion Prevention System (RIPS) at the Dallas Fort Worth International Airport (DFW) in October 2000. The RIPS combines airborne and ground sensor data with various cockpit displays to improve pilots' awareness of traffic conditions on the airport surface. The systems tested at DFW involved surface radar and data systems that gather and send surface traffic information to a research aircraft outfitted with the RIPS software, cockpit displays, and data link transceivers. The data sent to the airborne systems contained identification and GPS location of traffic. This information was compared with the own-ship location from airborne GPS receivers to generate incursion alerts. A total of 93 test tracks were flown while operating RIPS. This report compares the accuracy of the airborne GPS systems that gave the own-ship position of the research aircraft for the 93 test tracks.

    For monitoring and prediction of water-related hazards such as flash flooding in urban areas, high-resolution hydrologic and hydraulic modeling is necessary. Because of large sensitivity and scale dependence of rainfall-runoff models to errors in quantitative precipitation estimates (QPE), it is important that the accuracy of QPE be improved to the greatest extent possible. In this presentation, we describe the ongoing efforts in the Dallas-Fort Worth Metroplex area to provide location- and time-specific flash flooding warnings in real-time. The hydrologic modeling system used is the National Weather Service (NWS) Hydrology Laboratory's Research Distributed Hydrologic Model (HLRDHM) applied at spatiotemporal resolutions ranging from 250 m to 2 km and from 1 min to 1 hour. The high-resolution precipitation input is from the DFW Demonstration Network of the Collaborative Adaptive Sensing of the Atmosphere (CASA) radars, the Next Generation QPE (Q2), and the NWS Multisensor Precipitation Estimator (MPE). Also described are the assessment of sensitivity of streamflow simulation to the spatiotemporal resolution of precipitation input and hydrologic modeling, the needs for high-quality high-resolution precipitation data sets for hydro-meteorological and -climatological applications particularly in large urban areas, and possible approaches to realize them.

    This document is the Final Report of the Solar Energy System Installed at the First Solar Heated Office Building, One Solar Place, Dallas, Texas. The Solar System was designed to provide 87 percent of the space heating needs, 100 percent of the potable hot water needs and is sized for future absorption cooling. The collection subsystem consists of 28 Solargenics, series 76, flat plate collectors with a total area of 1596 square feet. The solar loop circulates an ethylene glycol-water solution through the collectors into a hot water system heat exchanger. The hot water storage subsystem consists of a heat exchanger, two 2300 gallon concrete hot water storage tanks with built in heat exchangers and a back-up electric boiler. The domestic hot water subsystem sends hot water to the 10,200 square feet floor area office building hot water fixtures. The building cold water system provides make-up to the solar loop, the heating loop, and the hot water concrete storage tanks. The design, construction, cost analysis, operation and maintenance of the solar system are described. The system became operational July 11, 1979.

    Aircraft departing from the Dallas/Fort Worth International Airport (DFW) encounter vertical restrictions that prevent continuous ascent operations. The result of these restrictions are temporary level-offs at 10,000 feet. A combination of flow direction, specific Area Navigation (RNAV) route geometry, and arrival streams have been found to be the biggest factors in the duration and frequency of a temporary level-offs. In total, 20% of DFW departures are affected by these level-offs, which have an average duration of just over 100 seconds. The use of continuous descent approaches at DFW are shown to lessen the impact arrivals have on the departures and allow more continuous ascents. The fuel used in a continuous ascent and an ascent with a temporary level-off have been calculated using a fuel burn rate model created from a combination of actual aircraft track data, aircraft manufacturer flight operations manuals, and Eurocontrol's Base of Aircraft Data (BADA) simulation tool. This model represents the average aggregate burn rates for the current fleet mix at DFW. Continuous ascents would save approximately seven gallons of fuel out of 450 gallons used to climb to a cruise altitude of 31,000ft per departure.

    Mass production of predatory stinkbugs in the laboratory is prioritized to release them into the field as part of IPM programs. Therefore, the aim of this study was to identify the best prey for rearing the predator Podisus nigrispinus (Dallas, 1851) (Hemiptera: Pentatomidae) among five different species of insect (three of Lepidoptera, one of Coleoptera, and one of Diptera). Second-instar P. nigrispinus nymphs were conditioned in transparent 1000-mL plastic pots, adults were placed in Petri dishes for mating, and both stages were maintained under controlled conditions (25 ± 1°C, 12 hours of photophase, 70 ± 10% RH). Nymphs and adults of P. nigrispinus consumed more Musca domestica (Linnaeus, 1758) (Diptera: Muscidae) larvae than the other tested prey. The consumption of fly larvae was 1.5 larvae/day/nymph and adults 1.7 larvae/day/adult. However, the number of eggs per female was less when the predator consumed M. domestica larvae (407.8 eggs/female) and most when consumed the Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) larvae (797.7 eggs/female). Furthermore, the percentage of hatched eggs was greater when the predator females consumed D. saccharalis larvae (90.0%). D. saccharalis larvae is the best prey to rearing P. nigrispinus.

    White Rock Lake reservoir in Dallas, Texas contains a 150-cm sediment record of silty clay that documents land-use changes since its construction in 1912. Pollen analysis corroborates historical evidence that between 1912 and 1950 the watershed was primarily agricultural. Land disturbance by plowing coupled with strong and variable spring precipitation caused large amounts of sediment to enter the lake during this period. Diatoms were not preserved at this time probably because of low productivity compared to diatom dissolution by warm, alkaline water prior to burial in the sediments. After 1956, the watershed became progressively urbanized. Erosion decreased, land stabilized, and pollen of riparian trees increased as the lake water became somewhat less turbid. By 1986 the sediment record indicates that diatom productivity had increased beyond rates of diatom destruction. Neither increased nutrients nor reduced pesticides can account for increased diatom productivity, but grain size studies imply that before 1986 diatoms were light limited by high levels of turbidity. This study documents how reservoirs may relate to land-use practices and how watershed management could extend reservoir life and improve water quality.

    Potential adaptive wake vortex spacing systems may need to rely on wake vortex decay rather than wake vortex transport in reducing wake separations. A wake vortex takeoff-spacing system in particular will need to rely on wake decay. Ambient turbulence is the primary influence on wake decay away from the ground. This study evaluated 18 months of ambient turbulence measurements at Dallas/Ft. Worth (DFW) Airport. The measurements show minor variation in the turbulence levels at various times of the year or times of the day for time periods when a departure system could be used. Arrival system operation was also examined, and a slightly lower overall turbulence level was found as compared to departure system benefit periods. The Sarpkaya model, a validated model of wake vortex behavior, was applied to various turbulence levels and compared to the DFW turbulence statistics. The results show that wake vortices from heavy aircraft on takeoff should dissipate within one minute for the majority of the time and will rarely last two minutes. These results will need to be verified by wake vortex measurements on departure.

    Background The absence of coronary artery calcium (CAC) in middle age is associated with very low short‐term risk for coronary events. However, the long‐term implications of a CAC score of 0 are uncertain, particularly among individuals with high cardiovascular lifetime risk. We sought to characterize the association between predicted lifetime risk and incident CAC among individuals with low short‐term risk. Methods and Results We included 754 Dallas Heart Study participants with serial CAC scans (6.9 years apart) and both low short‐term risk and baseline CAC=0. Lifetime risk for cardiovascular disease was estimated according to risk factor burden. Among this group, 365 individuals (48.4%) were at low lifetime risk and 389 (51.6%) at high lifetime risk. High lifetime risk was associated with higher annualized CAC incidence (4.2% versus 2.7%; P < 0.001). Similarly, mean follow‐up CAC scores were higher among participants with high lifetime risk (7.8 versus 2.4 Agatston units). After adjustment for age, sex, and race, high lifetime risk remained independently associated with incident CAC (OR 1.60; 95% CI 1.12 to 2.27; P=0.01). When assessing risk factor burden at the follow‐up visit, 66.7% of CAC incidence observed in the low lifetime risk group occurred among individuals reclassified to a higher short‐ or long‐term risk category. Conclusion Among individuals with low short‐term risk and CAC scores of 0, high lifetime risk is associated with a higher incidence of CAC. These findings highlight the importance of lifetime risk even among individuals with very low short‐term risk. PMID:25424574

    A shallow alluvial aquifer at the Naval Weapons Industrial Reserve Plant near Dallas, Texas, has been contaminated by organic solvents used in the fabrication and assembly of aircraft and aircraft parts. Natural gamma-ray and electromagnetic-induction log data collected during 1997 from 162 wells were integrated with existing lithologic and cone-penetrometer test log data to improve characterization of the subsurface alluvium at the site. The alluvium, consisting of mostly fine-grained, low-permeability sediments, was classified into low, intermediate, and high clay-content sediments on the basis of the gamma-ray logs. Low clay-content sediments were interpreted as being relatively permeable, whereas high clay-content sediments were interpreted as being relatively impermeable. Gamma-ray logs, cone-penetrometer test logs, and electromagnetic-induction logs were used to develop a series of intersecting sections to delineate the spatial distribution of low, intermediate, and high clay-content sediments and to delineate zones of potentially contaminated sediments. The sections indicate three major sedimentary units in the shallow alluvial aquifer at NWIRP. The lower unit consists of relatively permeable, low clay-content sediments and is absent over the southeastern and northwestern part of the site. Permeable zones in the complex, discontinuous middle unit are present mostly in the western part of the site. In the eastern and southeastern part of the site, the upper unit has been eroded away and replaced by fill material. Zones of potentially contaminated sediments are generally within the uppermost clay layer or fill material. In addition, the zones tend to be local occurrences.

    The objective of this research was to evaluate the consumer controlled factors of cooking method and degree of doneness on top loin steaks from different USDA quality grades (Low Choice, High Select or Low Select) and breed-types (English, Continental European Cross or Brahman Cross). In addition, cities within the same region were evaluated for differences in consumer controlled factors and palatability responses. The in-home product test was conducted in Dallas and San Antonio, Texas, USA. Consumers (n=173) evaluated steaks for overall like (OSAT), tenderness (TEND), juiciness (JUIC), and flavor (FLAV) using 23-point hedonic scales. Respondents in Dallas cooked their steaks to higher degrees of doneness than did those in San Antonio. Outdoor grilling was the most frequently used method of cookery for steaks in both cities. Generally, consumers in San Antonio gave higher palatability ratings to Choice steaks and Dallas consumers gave higher ratings to Select steaks. The interactions of city×cooking method, breed-type×cooking method, and degree of doneness×cooking method were significant for all palatability attributes. In addition, the interaction of cooking method×quality grade was significant for TEND, JUIC, and FLAV. Warner-Bratzler shear (WBS) force was determined on a steak from each strip loin. Steaks from Continental European Cross cattle and Low Choice carcasses had the lowest WBS values. Differences in consumer preparation of beef top loin steaks present very unique challenges for the beef industry. Consumer information programs may serve a valuable role in connecting consumer perceptions with the preparation techniques needed to consistently achieve satisfaction.

    The objective of this research was to evaluate the consumer controlled factors of cooking method and degree of doneness on top loin steaks from different USDA quality grades (Low Choice, High Select or Low Select) and breed-types (English, Continental European Cross or Brahman Cross). In addition, cities within the same region were evaluated for differences in consumer controlled factors and palatability responses. The in-home product test was conducted in Dallas and San Antonio, Texas, USA. Consumers (n=173) evaluated steaks for overall like (OSAT), tenderness (TEND), juiciness (JUIC), and flavor (FLAV) using 23-point hedonic scales. Respondents in Dallas cooked their steaks to higher degrees of doneness than did those in San Antonio. Outdoor grilling was the most frequently used method of cookery for steaks in both cities. Generally, consumers in San Antonio gave higher palatability ratings to Choice steaks and Dallas consumers gave higher ratings to Select steaks. The interactions of city×cooking method, breed-type×cooking method, and degree of doneness×cooking method were significant for all palatability attributes. In addition, the interaction of cooking method×quality grade was significant for TEND, JUIC, and FLAV. Warner-Bratzler shear (WBS) force was determined on a steak from each strip loin. Steaks from Continental European Cross cattle and Low Choice carcasses had the lowest WBS values. Differences in consumer preparation of beef top loin steaks present very unique challenges for the beef industry. Consumer information programs may serve a valuable role in connecting consumer perceptions with the preparation techniques needed to consistently achieve satisfaction. PMID:22064143

    The oil palm Elaeis guineensis is usually attacked by pests, particularly, defoliating caterpillars. Between 2004 and 2006 a stinkbug predator (Asopinae) was registered preying on caterpillars of Brassolis sophorae L., Opsiphanes invirae Hübner (Lepidoptera: Nymphalidae) and Sibine spp. (Lepidoptera: Limacodidae), reducing their populations in commercial oil palm plantations in the State of Pará, Brazil. Specimens of the natural enemy were collected, mounted, and identified as Alcaeorrhynchus grandis (Dallas) (Hemiptera: Pentatomidae), corresponding to the first report of the occurrence of this stinkbug attacking defoliating caterpillars of oil palm in Brazil.

    The report documents a study conducted to assess and test promising technologies for HOV land enforcement. After a qualitative assessment of video, automatic vehicle identification, and infrared machine vision technologies, the study was suspended because no preferred infrared technology was available for testing. The study was resumed when a vendor demonstrated promising video technology. The high-occupancy vehicle enforcement and review (HOVER) system was then developed for an operational test on the East R.L. Thorton (I-30) contraflow HOV lane in Dallas, Texas.

    The objectives of this fact sheet are to summarize the occurrence of water-borne PAHs in three urban streams in the Dallas- Fort Worth metropolitan area and to assess the use of semipermeable membrane devices (SPMDs) as PAH samplers. One site on each of three streams was selected for monitoring the occurrence of PAHs (fig. 1). The sites were chosen to reflect varied urban land uses and the influences of point- and nonpointsource pollution. The monitoring was done using SPMDs during a 30-day period in late May and June 1994.

    Mountain Creek Lake is a reservoir adjacent to two U.S. Department of the Navy facilities, the Naval Weapons Industrial Reserve Plant and the Naval Air Station in Dallas, Texas. A Resource Conservation and Recovery Act Facility Investigation found ground-water plumes containing chlorinated solvents on both facilities. These findings led to a U.S. Geological Survey study of Mountain Creek Lake adjacent to both facilities between June 1994 and August 1996. Bottom sediments, lake water, bottom-sediment pore water, and fish were collected for chemical analysis.

    Errors in runoff prediction caused by input data errors are analyzed by treating precipitation-runoff models as regression (conditional expectation) models. Independent variables of the regression consist of precipitation and other input measurements; the dependent variable is runoff. In models using erroneous input data, prediction errors are inflated and estimates of expected storm runoff for given observed input variables are biased. A case study using a set of data from Turtle Creek near Dallas, Texas illustrates the problems of model input errors. -from Author

    Urban flash flood is one of the most commonly encountered hazardous weather phenomena. Unfortunately, the rapid urbanization has made the densely populated areas even more vulnerable to flood risks. Hence, accurate and timely monitoring of rainfall at high spatiotemporal resolution is critical to severe weather warning and civil defense, especially in urban areas. However, it is still challenging to produce high-resolution products based on the large S-band National Weather Service (NWS) Next-Generation Weather Radar (NEXRAD), due to the sampling limitations and Earth curvature effect. Since 2012, the U.S. National Science Foundation Engineering Research Center (NSF-ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA) has initiated the development of Dallas-Fort Worth (DFW) radar remote sensing network for urban weather hazards mitigation. The DFW urban radar network consists of a combination of high-resolution X-band radars and a standard NWS NEXRAD radar operating at S-band frequency. High-resolution quantitative precipitation estimation (QPE) is one of the major research goals in the deployment of this urban radar network. It has been shown in the literature that the dual-polarization radar techniques can improve the QPE accuracy over traditional single-polarization radars by rendering more measurements to enhance the data quality, providing more information about rain drop size distribution (DSD), and implying more characteristics of different hydrometeor types. This paper will present the real-time dual-polarization CASA DFW QPE system, which is developed via fusion of observations from both the high-resolution X band radar network and the S-band NWS radar. The specific dual-polarization rainfall algorithms at different frequencies (i.e., S- and X-band) will be described in details. In addition, the fusion methodology combining observations at different temporal resolution will be presented. In order to demonstrate the capability of rainfall

    Objective To examine relationship between neighborhood-level socioeconomic deprivation and weight change in a multi-ethnic cohort from Dallas County, Texas and whether behavioral/psychosocial factors attenuate the relationship. Methods Non-movers (those in the same neighborhood throughout the study period) aged 18–65 (N=939) in Dallas Heart Study (DHS) underwent weight measurements between 2000–2009 (median 7-year follow-up). Geocoded home addresses defined block groups; a neighborhood deprivation index (NDI) was created (higher NDI=greater deprivation). Multi-level modeling determined weight change relative to NDI. Model fit improvement was examined with adding physical activity and neighborhood environment perceptions (higher score=more unfavorable perceptions) as covariates. A significant interaction between residence length and NDI was found (p-interaction=0.04); results were stratified by median residence length (11 years). Results Adjusting for age, sex, race/ethnicity, smoking, education/income, those who lived in neighborhood>11 years gained 1.0 kilograms (kg) per one-unit increment of NDI (p=0.03), or 6 kg for those in highest NDI tertile compared with those in the lowest tertile. Physical activity improved model fit; NDI remained associated with weight gain after adjustment for physical activity and neighborhood environment perceptions. There was no significant relationship between NDI and weight change for those in their neighborhood≤11 years. Conclusions Living in more socioeconomically deprived neighborhoods over a longer time period was associated with weight gain in DHS. PMID:24875231

    Limited capital investment for major transportation improvements and growth in metropolitan areas require the most efficient use of the existing transportation system. One means to achieve this is high-occupancy vehicle (HOV) lanes. While an extensive system of permanent HOV lanes is planned for the Dallas-Fort Worth urbanized area, the Texas Department of Transportation (TxDOT) and Dallas Area Rapid Transit (DART) have pursued and continue to pursue short-term or interim HOV lane projects that would enhance public transportation and overall mobility. There are currently 57 km (35.4 mi) of interim HOV lanes operational in the Dallas area, including a barrier-separated contraflow lane on I-30 (East R.L. Thornton Freeway) and buffer-separated concurrent flow HOV lanes on I-35E North (Stemmons Freeway) and I-635 (Lyndon B. Johnson Freeway). The objective of this research is to investigate the operational effectiveness of concurrent flow (buffer-separated) versus contraflow (barrier-separated) HOV lanes. Issues such as person movement, carpool formation, travel time savings, violation rates, and project cost effectiveness are addressed. By understanding the operational performance and issues of both concurrent flow (buffer-separated) HOV lanes and contraflow (barrier-separated) HOV lanes, recommendations can be made on suggested HOV lane policies, including the type of permanent HOV lanes to be implemented in the Dallas area.

    Semipermeable membrane devices (SPMDs) and Asiatic clams, Corbicula fluminea (MuLLER), were deployed at stream sites in the Dallas-Fort Worth Metropolitan Area to assess the presence of bioavailable, dissolved polycyclic aromatic hydrocarbons (PAHs). Twenty-four PAHs were detected in SPMDs, 20 of which occurred at all sites. Only three PAHs were detected in the co-deployed clams. Throughout all sites, non-alkylated PAHs were found at greater levels in SPMDs than alkylated forms. Nine of 16 Priority Pollutant PAHs were detected in SPMDs. Estimated concentrations of PAHs in water were generally two to three orders of magnitude less than standard minimum analytical reporting levels; however, for bent (a) anthracene, benzo (a) pyrene, and chrysene, estimated concentrations in water exceeded the U.S. Environmental Protection Agency's human health criteria for these carcinogens in water and aquatic organisms.

    The quality of urban stormwater is characterized with respect of 188 properties and constituents. Event-mean concentrations and loads for three land uses (residential, industrial, commercial), and annual loads for 12 selected properties and constituents for 26 gaged basins in the Dallas-Forth Worth study area are presented. Event-mean concentrations (EMCs) were computed for each land use for biochemical oxygen demand; chemical oxygen demand; suspended and dissolved solids; total nitrogen and ammonia plus organic nitrogen; total and dissolved phosphorus; total recoverable copper, lead, and zinc; and total diazinon. The EMCs of chemical oxygen demand; total nitrogen and ammonia plus organic nitrogen; total and dissolved phosphorus; and total diazinon were greatest in samples from residential land-use basins. The EMCs of biochemical oxygen demand; suspended and dissolved solids; and total copper, lead, and zinc were greatest in samples from industrial land-use basins.

    Therapies targeting high density lipoprotein cholesterol content (HDL-C) have not improved coronary heart disease (CHD) outcomes. HDL particle concentration (HDL-P) may better predict CHD. However, the impact of race/ethnicity on the relations between HDL-P and subclinical atherosclerosis/ incident CHD events has not been described. Participants from the Dallas Heart Study, a multiethnic, probability-based, population cohort of Dallas County adults had the following baseline measurements: HDL-C, HDL-P by nuclear magnetic resonance imaging (NMR), and coronary artery calcium (CAC) by electron beam computed tomography. Participants were followed for a median of 9.3 years for incident CHD events (composite of first myocardial infarction, stroke, coronary revascularization, or cardiovascular death). The study comprised 1977 participants free from CHD (51% women, 46% Black). In adjusted models, HDL-C was not associated with prevalent CAC (p=0.13) or incident CHD overall (HR per 1SD: 0.89, 95% CI 0.76–1.05). However, HDL-C was inversely associated with incident CHD among non-Black (adjusted HR per 1SD 0.67, 95% CI 0.46–0.97) but not Black participants (HR 0.94, 95% CI 0.78–1.13, pinteraction = 0.05). Conversely, HDL-P, adjusted for risk factors and HDL-C, was inversely associated with prevalent CAC (p=0.009) and with incident CHD overall (adjusted HR per 1SD: 0.73, 95% CI 0.62–0.86) with no interaction by Black race/ethnicity (pinteraction = 0.57). In conclusion, in contrast to HDL-C, the inverse relationship between HDL-P and incident CHD events is consistent across ethnicities. These findings suggest that HDL-P is superior to HDL-C in predicting both prevalent atherosclerosis as well as incident CHD events across a diverse population and should be considered as a therapeutic target.

    From October 2002 to April 2004, data were collected from Dallas/Fort Worth (DFW) International Airport (TX, U.S.A.) outfalls and receiving waters (Trigg Lake and Big Bear Creek) to document the magnitude and potential effects of aircraft deicer and anti-icer fluid (ADAF) runoff on water quality. Glycol concentrations at outfalls ranged from less than 18 to 23,800 mg/L, whereas concentrations in Big Bear Creek were less because of dilution, dispersion, and degradation, ranging from less than 18 to 230 mg/L. Annual loading results indicate that 10 and 35% of what was applied to aircraft was discharged to Big Bear Creek in 2003 and 2004, respectively. Glycol that entered Trigg Lake was diluted and degraded before reaching the lake outlet. Dissolved oxygen (DO) concentrations at airport outfalls sometimes were low (<2.0 mg/L) but typical of what was measured in an urban reference stream. In comparison, the DO concentration at Trigg Lake monitoring sites was consistently greater than 5.5 mg/L during the monitoring period, probably because of the installation of aerators in the lake by DFW personnel. The DO concentration in Big Bear Creek was very similar at sites upstream and downstream of airport influence (>5.0 mg/L). Results of toxicity tests indicate that effects on Ceriodaphnia dubia, Pimephales promelas, and Selanastrum capricornutum are influenced by type IV ADAF (anti-icer), not just type I ADAF (deicer) as is more commonly assumed.

    The quality of the Aircraft Vortex Spacing System (AVOSS) is critically dependent on representative wind profiles in the atmospheric boundary layer. These winds observed from a number of sensor systems around the Dallas-Fort Worth airport were combined into single vertical wind profiles by an algorithm developed and implemented by MIT Lincoln Laboratory. This process, called the AVOSS Winds Analysis System (AWAS), is used by AVOSS for wake corridor predictions. During times when AWAS solutions were available, the quality of the resultant wind profiles and variance was judged from a series of plots combining all sensor observations and AWAS profiles during the period 1200 to 0400 UTC daily. First, input data was evaluated for continuity and consistency from criteria established. Next, the degree of agreement among all wind sensor systems was noted and cases of disagreement identified. Finally, the resultant AWAS solution was compared to the quality-assessed input data. When profiles differed by a specified amount from valid sensor consensus winds, times and altitudes were flagged. Volume one documents the process and quality of input sensor data. Volume two documents the data processing/sorting process and provides the resultant flagged files.

    Phospholipase C from the Dallas 1E strain of Legionella pneumophila serogroup 5 was purified from buffered yeast extract culture supernate by ion-exchange chromatography followed by fractionation by manganous chloride and ammonium sulphate precipitation steps. Enzyme activity was assayed by hydrolysis of p-nitrophenylphosphorylcholine and confirmed by release of radioactivity from tritiated L-alpha-dipalmitoylphosphatidylcholine labelled in the methyl groups of choline. After SDS-PAGE, the purified preparation yielded a single band upon Coomassie-blue staining. This protein migrated with an apparent Mr of 50,000-54,000. Phospholipase C activity was maximal at pH greater than or equal to 8.4 and was enhanced in the presence of sorbitol and of several nonionic detergents but was eliminated by SDS. EDTA, Cu2+, Fe2+ and Zn2+ inhibited enzyme activity, whereas Ba2+, Ca2+, Co2+, Mg2+ and Mn2+ restored activity to EDTA-treated material. No haemolytic activity was demonstrated with the purified enzyme. PMID:3171547

    Currently, the National Weather Service (NWS) Next Generation Weather Radar (NEXRAD) provides observations updated every five-six minutes across the United States. However, at the maximum NEXRAD operating range of 230 km, the 0.5 degree radar beam (lowest tilt) height is about 5.4 km above ground level (AGL) because of the effect of Earth curvature. Consequently, much of the lower atmosphere (1-3 km AGL) cannot be observed by the NEXRAD. To overcome the fundamental coverage limitations of today's weather surveillance radars, and improve the spatial and temporal resolution issues, at urban scale, the National Science Foundation Engineering Research Center (NSF-ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA) has embarked the development of Dallas-Fort worth (DFW) urban remote sensing network to conduct high-resolution sensing in the lower atmosphere for a metropolitan environment, communicate high resolution observations and nowcasting of severe weather including flash floods, hail storms and high wind events. Being one of the largest inland metropolitan areas in the U.S., the DFW Metroplex is home to over 6.5 million people by 2012 according to the North Central Texas Council of Governments (NCTCOG). It experiences a wide range of natural weather hazards, including urban flash flood, high wind, tornado, and hail, etc. Successful monitoring of the rapid changing meteorological conditions in such a region is necessary for emergency management and decision making. Therefore, it is an ideal location to investigate the impacts of hazardous weather phenomena, to enhance resilience in an urban setting and demonstrate the CASA concept in a densely populated urban environment. The DFW radar network consists of 8 dual-polarization X-band weather radars and standard NEXRAD S-band radar, covering the greater DFW metropolitan region. This paper will present high resolution observation of tornado, urban flood, hail storm and damaging wind event all within the

    Background/Objectives: Visceral adipose tissue (VAT) mass, a risk factor for cardiometabolic complications of obesity, is usually measured by magnetic resonance imaging (MRI) but this method is not practical in a clinical setting. In contrast, measurement of VAT by dual-x-ray absorptiometry (DXA) appears to circumvent the limitations of MRI. In this study, we compared measurements of VAT mass by MRI and DXA in the large, multiethnic cohort of the Dallas Heart Study (DHS). Subjects/Methods: About 2689 DHS participants underwent paired measurement of VAT by MRI and DXA. Sex-stratified analyses were performed to evaluate the correlation and agreement between DXA and MRI. Model validation was performed using bootstrapping and inter-reader variability was assessed. Results: Mean age of the cohort was 44 years, with 55% female, 48% Black and 75% overweight/obese participants. Regression analysis showed a linear relationship between DXA and MRI with R2=0.82 (95% confidence interval (CI) 0.81–0.84) for females and R2=0.86 (95% CI 0.85–0.88) for males. Mean difference between methods was 0.01 kg for females and 0.09 kg for males. Bland–Altman analysis showed that DXA tended to modestly underestimate VAT compared with MRI at lower VAT levels and overestimate it compared with MRI at higher VAT levels. Results were consistent in analyses stratified by race, body mass index status, waist girth and body fat. Inter-individual reader correlation among 50 randomly selected scans was excellent (inter-class correlation coefficient=0.997). Conclusions: VAT mass quantification by DXA was both accurate and valid among a large, multiethnic cohort within a wide range of body fatness. Further studies including repeat assessments over time will help determine its long-term applicability. PMID:27428873

    Specific chemokines contribute to vascular inflammation and may be useful biomarkers to detect atherosclerosis. The chemokines CXCL1 and CCL11 have previously been studied in animal or human models of atherosclerosis, while CXCL2 and CCL23 have not. Among 2,454 subjects enrolled in the Dallas Heart Study, a multi-ethnic population-based sample, we measured plasma CCL11, CCL23, CXCL1, and CXCL2, and associated levels with coronary artery calcium (CAC) by computed tomography, and aortic wall thickness, plaque burden, and compliance by magnetic resonance imaging. Elevated chemokine levels were defined as greater than or equal to the median for CCL11 and CCL23 and greater than or equal to the upper detection limit for CXCL1 and CXCL2. Elevated CCL23 (P < 0.01) and CXCL1 (P = 0.01), but not CCL11 and CXCL2, associated with CAC in univariable analyses. After adjustment for traditional risk factors, elevated CCL23 remained associated with CAC (OR 1.3, 95% CI 1.0-1.7; P = 0.02), while the association with CXCL1 was modestly attenuated (OR 1.4, 95% CI 1.0-2.1; P = 0.06). CCL23 also associated with aortic wall thickness, plaque, and compliance in univariable analyses (P < 0.05 for each), but these associations were attenuated after multivariable adjustment. The novel chemotactic protein, CCL23, which has not been previously studied in atherosclerosis, is independently associated with coronary atherosclerosis, suggesting that this chemokine merits further study in animal and human models.

    Historical trends in selected water-quality variables from 1912 to 1994 in White Rock Creek Basin were identified by dated sediment cores from White Rock Lake. White Rock Lake is a 4.4-km2 reservoir filled in 1912 and located on the north side of Dallas, Texas, with a drainage area of 259 km2. Agriculture dominated land use in White Rock Creek Basin before about 1950. By 1990, 72% of the basin was urban. Sediment cores were dated using cesium-137 and core lithology. Major element concentrations changed, and sedimentation rates and percentage of clay-sized particles in sediments decreased beginning in about 1952 in response to the change in land use. Lead concentrations, normalized with respect to aluminum, were six times larger in sediment deposited in about 1978 than in pre-1952 sediment. Following the introduction of unleaded gasoline in the 1970s, normalized lead concentrations in sediment declined and stabilized at about two and one-half times the pre-1952 level. Normalized zinc and arsenic concentrations increased 66 and 76%, respectively, from before 1952 to 1994. No organochlorine compounds were detected in sediments deposited prior to about 1940. Concentrations of polychlorinated biphenyls (PCB) and DDE (a metabolite of DDT) increased rapidly beginning in the 1940s and peaked in the 1960s at 21 and 20 ??g kg-1, respectively, which is coincident with their peak use in the United States. Concentrations of both declined about an order of magnitude from the 1960s to the 1990s to 3.0 and 2.0 ??g kg-1, respectively. Chlordane and dieldrin concentrations increased during the 1970s and 1980s. The largest chlordane concentration was 8.0 ??g kg-1 and occurred in a sediment sample deposited in about 1990. The largest dieldrin concentration was 0.7 ??g kg-1 and occurred in the most recent sample deposited in the early 1990s. Agricultural use of chlordane and dieldrin was restricted in the 1970s; however, both were used as termiticides, and urban use of chlordane

    Combined magnetic and geochemical studies were conducted on sediments from White Rock Lake, a reservoir in suburban Dallas (USA), to investigate how land use has affected sediment and water quality since the reservoir was filled in 1912. The chronology of a 167-cm-long core is constrained by the recognition of the pre-reservoir surface and by 137Cs results. In the reservoir sediments, magnetic susceptibility (MS) and isothermal remanent magnetization (IRM) are largely carried by detrital titanomagnetite that originally formed in igneous rocks. Titanomagnetite and associated hematite are the dominant iron oxides in a sample from the surficial deposit in the watershed but are absent in the underlying Austin Chalk. Therefore, these minerals were transported by wind into the watershed. After about 1960, systematic decreases in Ti, Fe, and Al suggest diminished input of detrital Fe-Ti oxides from the surficial deposits. MS and IRM remain constant over this interval, however, implying compensation by an increase in strongly magnetic material derived from human activity. Anthropogenic magnetite in rust and ferrite spherules (from fly ash?) are more common in sediment deposited after about 1970 than before and may account for the constant magnetization despite the implied decrease in detrital Fe-Ti oxides. An unexpected finding is the presence of authigenic greigite (Fe3S4), the abundance of which is at least partly controlled by climate. Greigite is common in sediments that predate about 1975, with zones of concentration indicated by relatively high IRM/MS. High greigite contents in sediment deposited during the early to mid-1950s and during the mid-1930s correspond to several-year periods of below-average precipitation and drought from historical records. Relatively long water-residence times in the reservoir during these periods may have led to elevated levels of sulfate available for bacterial sulfate reduction. The sulfate was probably derived via the oxidation of

  18. Cloud and Cloud-to-ground Lightning Detection at LF and VHF: Early Results from Global Atmospherics' Dallas-Fort Worth LDAR-II and IMPACT/ESP Research Networks

    NASA Astrophysics Data System (ADS)

    Demetriades, N.; Murphy, M. J.; Cummins, K. L.

    2001-12-01

    Global Atmospherics, Inc. (GAI) recently installed a regional Lightning Detection and Ranging (LDAR-II) network and a regional VLFLF lightning detection network of IMPACTESP and LPATS IV sensors (configured to detect both cloud-to-ground lightning and cloud discharges) for research purposes in the vicinity of Dallas-Fort Worth (DFW) International Airport. The LDAR-II and VLF/LF networks became fully operational on 1 March 2001 and 10 June 2001, respectively. The DFW LDAR-II network is made up of 7 sensors, with 20 to 30 km baselines, that can detect pulses of radiation produced by the electrical breakdown processes of lightning in a 5-MHz band within a subset of the VHF (50-120 MHz) band. This regional LDAR-II network can map lightning flashes in 3-dimensions within approximately 150 km of the center of the network, degrading in performance with increasing range. Expected lightning flash detection efficiency is greater than 99% within the interior of the DFW LDAR-II network (a range of 30 km from DFW International Airport) and greater than 90% out to a range of 150 km from DFW International Airport. Expected three-dimensional location accuracy for individual pulses of radiation is better than 100 m within the interior of the network and better than 2 km to a range of 150 km from the network center. Early analysis of the DFW LDAR-II and VLF/LF networks has involved comparisons with the U.S. National Lightning Detection Network (NLDN) and radar base reflectivity images from the DFW National Weather Service (NWS) radar. The results of these comparisons will be summarized for representative thunderstorm cases. In addition, a specific case involving an extensive "spider lightning" discharge will be presented. This discharge originated at a distance of more than 50 km from DFW airport, traveled a total path of approximately 150 km, and initiated four isolated cloud-to-ground discharges - one of which resulted in a safety-related incident at DFW airport.

    2009-10-01

    A culture of quality improvement (QI) is needed to bridge the gap between possible STEEEP (safe, timely, effective, efficient, equitable, and patient-centered) care and actual usual care. Baylor Health Care System (BHCS) developed Accelerating Best Care at Baylor (ABC Baylor), an innovative educational program that teaches health care leaders the theory and techniques of rapid-cycle QI. Course participants learn general principles of continuous QI, as well as health care-specific QI techniques, and finish the course by designing and implementing their own QI project. ABC Baylor has been employed in a variety of settings and has spread its success to other organizations, especially small and rural hospitals. These hospitals, like BHCS, have demonstrated sustained improvements that are due in part to the use of ABC Baylor and its reliance on specific modules that focus on health care safety, service, equity, and chronic disease management. The role of ABC Baylor training and consulting is part of the overall culture and infrastructure that have allowed BHCS to achieve success in its improvement journey, including the receipt of several national awards and the achievement of high reliability in compliance with Centers for Medicare and Medicaid Services core measures of processes of care related to heart failure, acute myocardial infarction, community-acquired pneumonia, and surgical care. The culture of rapid-cycle QI facilitated by ABC Baylor serves to link BHCS's vision and goals to practical execution. PMID:19865500

  20. Occurrence and distribution of fecal indicator bacteria, and physical and chemical indicators of water quality in streams receiving discharge from Dallas/Fort Worth International Airport and vicinity, North-Central Texas, 2008

    This report, done by the U.S. Geological Survey in cooperation with Dallas/Fort Worth International (DFW) Airport in 2008, describes the occurrence and distribution of fecal indicator bacteria (fecal coliform and Escherichia [E.] coli), and the physical and chemical indicators of water quality (relative to Texas Surface Water Quality Standards), in streams receiving discharge from DFW Airport and vicinity. At sampling sites in the lower West Fork Trinity River watershed during low-flow conditions, geometric mean E. coli counts for five of the eight West Fork Trinity River watershed sampling sites exceeded the Texas Commission on Environmental Quality E. coli criterion, thus not fully supporting contact recreation. Two of the five sites with geometric means that exceeded the contact recreation criterion are airport discharge sites, which here means that the major fraction of discharge at those sites is from DFW Airport. At sampling sites in the Elm Fork Trinity River watershed during low-flow conditions, geometric mean E. coli counts exceeded the geometric mean contact recreation criterion for seven (four airport, three non-airport) of 13 sampling sites. Under low-flow conditions in the lower West Fork Trinity River watershed, E. coli counts for airport discharge sites were significantly different from (lower than) E. coli counts for non-airport sites. Under low-flow conditions in the Elm Fork Trinity River watershed, there was no significant difference between E. coli counts for airport sites and non-airport sites. During stormflow conditions, fecal indicator bacteria counts at the most downstream (integrator) sites in each watershed were considerably higher than counts at those two sites during low-flow conditions. When stormflow sample counts are included with low-flow sample counts to compute a geometric mean for each site, classification changes from fully supporting to not fully supporting contact recreation on the basis of the geometric mean contact

    We received our first CO2 laser at Baylor University Medical Center in December 1974, following a trip to Israel in January of that year. Discussion with the customs office of the propriety of charging an 18% import tax lasted for nine months. We lost that argument. Baylor has been using lasers of many types for many procedures since that time. About ten years ago, through the kindness of Tom Dougherty and Roswell Park, we started working with photodynamic therapy, first with hematoporphyrin I and later with dihematoporphyrin ether (II). In February 1984, we were invited to a conference at Los Alamos, New Mexico, U.S.A. on medical applications of the free electron laser as part of the Star Wars Program. A grant application from Baylor was approved that November, but funding did not start for many months. This funding contributed to the development of a new research center as part of Baylor Research Institute. Many of the projects investigated at Baylor dealt with applications of the free electron laser (FEL), after it became available. A staff was assembled and many projects are still ongoing. I would like to outline those which are in some way related to photodynamic therapy.

    Moring, J. Bruce

    2009-01-01

    In 2001, the U.S. Geological Survey National Water Quality Assessment Program began a series of studies in the contiguous United States to examine the effects of urbanization on the chemical, physical, and biological characteristics of streams. Small streams in the Texas Blackland Prairie level III ecoregion in and near the Dallas-Fort Worth metropolitan area were the focus of one of the studies. The principal objectives of the study, based on data collected in 2003-04 from 28 subbasins of the Trinity River Basin, were to (1) define a gradient of urbanization for small Blackland Prairie streams in the Trinity River Basin on the basis of a range of urban intensity indexes (UIIs) calculated using land-use/land-cover, infrastructure, and socioeconomic characteristics; (2) assess the relation between this gradient of urbanization and the chemical, physical, and biological characteristics of these streams; and (3) evaluate the type of relation (that is, linear or nonlinear, and whether there was a threshold response) of the chemical, physical, and biological characteristics of these streams to the gradient of urbanization. Of 94 water-chemistry variables and one measure of potential toxicity from a bioassay, the concentrations of two pesticides (diazinon and sima-zine) and one measure of potential toxicity (P450RGS assay) from compounds sequestered in semipermeable membrane devices were significantly positively correlated with the UII. No threshold responses to the UII for diazinon and simazine concentrations were observed over the entire range of the UII scores. The linear correlation for diazinon with the UII was significant, but the linear correlation for simazine with the UII was not. No statistically significant relations between the UII and concentrations of suspended sediment, total nitrogen, total phosphorous, or any major ions were indicated. Eleven of 59 physical variables from streamflow were significantly correlated with the UII. Temperature was not

    1987-01-01

    Archaeological work in the Little Tennessee River Valley was very much affected by the fluctuations in the Tellico Reservoir scheduling and funding. Stated project goals were: ''Questions regarding Cherokee origins, culture change and acculturation, and the length of time during which the valley was inhabited by man will be among the major ones to be considered.'' From the project inception, the principal research commitment was to the eighteenth century Overhill Cherokee occupation of the valley. By 1967, the inundation date was set for 1971. Four main research problems were identified: (1) a complete survey of the reservoir area to locate all prehistoric and historic sites that will be inundated; (2) a thorough testing of the eighteenth century Cherokee towns to determine the effects of acculturation; (3) to determine how long the Overhill Cherokee have occupied the Little Tennessee Valley by excavating a late prehistoric Mississippian village or an early Historic Cherokee village to discover by (sic) continuities between the prehistoric Mississippian complexes and the Historic Cherokee; and (4) to test intensively occupied sites in depth to find earlier Woodland and Archaic complexes in stratigraphic succession (Guthe, 1967). This report describes the results of these investigations.

    Comparison of instantaneous flux values of selected organic compounds in water from downstream sites indicates: (1) the formation of chloroform in the stream following the discharge of the treated effluent, and that (2) instream biodegradation may be decreasing concentrations of linear alkylbenzene compounds in water. The relative persistence of many of the selected organic compounds in Rowlett Creek downstream from the municipal wastewater-treatment plant indicates that they could be transported into Lake Ray Hubbard, a source of municipal water supply.

    1995-03-01

    Public concerns about surface water quality and its impact on health issues have put a premium on the ability to predict surface and groundwater quality in urban areas. The movement of toxins and nutrients in urban areas is largely controlled by interactions with soil and aquifer minerals along hydrologic pathways. Despite progress in theoretical modeling of the effects of these interactions on water chemistry, it is presently impossible to predict overall trends in urban water quality. Determining the controls on stream water chemistry is problematic due to the interplay between different hydrologic reservoirs which cannot be easily observed or measured. Natural tracers, such as dissolved ions and isotopes, provide an indirect method for observing subsurface interactions and are useful for time series analysis of stream water composition. Ionic species are generally nonconservative components because of chemical reactions and are thus useful for discerning the overall discharge chemistry affected by the relationship.

    Many cities experience loss of vegetation due to urbanization. A recognized result of this defoliation is the occurrence of hot spots' which act to increase the temperature of surrounding areas. These heat islands' lead to higher energy consumption and costs. In this study a methodology was developed to produce thermal/land cover satellite images of areas in the Metroplex using visible, infrared and thermal TM bands. An index of vegetation cover was made from bands 3 and 4 to differentiate areas of vegetation and to provide a basis for temperature comparisons. TM band 6 was merged with the vegetation index image, classified and color coded to show temperature differences in the study areas, then verified in the field. Verified hot spots included roads, parking lots, strip malls and developed intersections. This study was done in cooperation with the Texas Forest Service in an effort to identify heat islands that need tree planting to help cool down cities and filter out harmful air pollutants.

    The greatest flood since at least 1892 on Cottonwood Creek and Floyd Branch occurred June 14, 1949. The storm of October 8, 1962, caused flood heights at Forest Lane to be comparable to those of June 14, 1949, on Cottonwood Creek and about 1 foot lower on Floyd Branch. The greatest flood since at least 1917 on Spanky Branch was that of September 21, 1964. Greater floods than those delineated are possible.

    Two hundred thirteen male police officers between 21 and 52 years of age volunteered to participate in a physical evaluation and conditioning program. Information concerning the physical fitness status and risk of coronary heart disease (CHD) of police officers were shown. Younger police officers (less than 30 years of age) were average in physical fitness levels and CHD risk compared to the population of the same age. Middle-aged police officers were shown to be lower in physical fitness levels and higher in CHD risk compared to their cohorts. The results from this investigation support the need for physical fitness and preventive medicine programs for police officers.

    The analyses indicate that in a fully-developed residential area, the flood peaks will be 1.2 to 1.4 times those from an undeveloped area; and the annual direct runoff will be about double that from an undeveloped area. Data were not sufficient to determine the increase in runoff from a highly industrialized area where the effective imperviousness approaches 100 percent.

    The flood was caused by a 5-hour storm in the early hours of April 28. Antecedent rainfall had so saturated the area that the intense, but relatively low, total rainfall (less than a 50-year return period) caused historical floods to be exceeded at many points. A peak runoff rate of 3,160 cubic feet per second per square mile occurred on a 1.5 square-mile area within the watershed.

  16. Comparison between three different traffic micro-simulations and reality in Dallas

    It is certainly desirable that transportation forecasting models are correct in the sense that the traffic patterns they predict correspond to what would happen in reality under the circumstances assumed in the forecasting model. Unfortunately, it is notoriously difficult to transform the above common sense statement into a technical specification. Since one cannot run controlled experiments in socio-economic systems, it is usually impossible to check the forecasts. The authors describe three traffic microsimulations which operate at different levels of fidelity. They are used to iteratively generate a self-consistent route-set based upon microsimulation feedback. They compare the simulation results of all three simulations to aggregated turn count data of actual field measurements.

    Minimally invasive surgery consisting of bipolar radiofrequency pulmonary vein (PV) isolation and limited ganglionated plexus ablation is effective in eliminating atrial fibrillation (AF) in patients with paroxysmal AF but is less effective in those with persistent AF or long-standing persistent AF. The purpose of this study was examine the results of minimally invasive surgery incorporating an additional set of radiofrequency ablation lines replicating a left-sided Cox maze III procedure. Thirty patients with persistent AF (n = 10) or long-standing persistent AF (n = 20) underwent minimally invasive surgery with an extended lesion set and PV isolation for a minimum follow-up of 6 months. Linear lesions were created at the roof line, at the anterior line, and between the roof line and the left atrial appendage. All patients underwent limited ganglionated plexus ablation and left atrial appendage excision as well as PV isolation verification. Block across the roof and anterior lines was confirmed in 29 (96.6%) of the 30 patients. Follow-up included 2-week event monitoring with auto-trigger in 21 patients, pacemaker interrogation in 8, and ECG in 1 who was in AF and refused longer-term monitoring. No operative mortality or major morbidity occurred. At 6 months, 24 (80%) of the 30 patients were free of AF: 15 (75%) with long-standing persistent AF and 9 (90%) with persistent AF. Among the six failures, burden of AF was low: one had 1 episode >15 seconds, two had 4 episodes, one had 6 episodes, one had >50 episodes, and one had AF on ECG and refused further monitoring. Early results of minimally invasive surgery with a new extended linear lesion set suggest increased efficacy over PV isolation and limited ganglionated plexus ablation in patients with persistent AF or long-standing persistent AF.

    2013-01-01

    Spot and Runway Departure Advisor (SARDA) is a proposed decision-support tool for air traffic control tower controllers for reducing taxi delay and optimizing the departure sequence. In the present study, the tool's usability was evaluated to ensure that its claimed performance benefits are not being realized at the cost of increasing the work burden on controllers. For the evaluation, workload ratings and questionnaire responses collected during a human-in-the-loop simulation experiment were analyzed to assess the SARDA advisories' effects on the controllers' ratings on cognitive resources (e.g., workload, spare attention) and satisfaction. The results showed that SARDA reduced the controllers' workload and increased their spare attention. It also made workload and attention levels less susceptible to the effects of increases in the traffic load. The questionnaire responses suggested that the controllers generally were satisfied with the ease of use of the tool and the objectives of the SARDA concept, but with some caution. To gain more trust from controllers, the the reasoning behind advisories may need to be made more transparent to them.

    The results of borehole geophysical log analysis indicate that two of the production wells could have vertically connected intervals where cement bonding in the well annulus is poor. The other production wells have overall good bonding. Temperature logs do not indicate flow behind casing except in the screened interval of one well. Geophysical logs show the Eagle Ford Shale ranges from 147 to 185 feet thick at the site. The Eagle Ford Shale has low permeability and a high plasticity index. These physical characteristics make the Eagle Ford Shale an excellent confining unit.

  3. Effects of gamma radiation on nymphal development and reproductive capacity of the large milkweed bug, Oncopeltus fasciatus (Dallas) (Hemiptera - Lygaeidae)

    SciTech Connect

    Moursy, L.E.

    1985-01-01

    Gamma radiation adversely affected important fitness components of Oncopeltus fasciatus, particularly as expressed by nymphal development, subsequent reproductive capacity, mating competitiveness and longevity. Early treated 5th instar nymphs are about 2X more sensitive to gamma radiation than late treated 5th instar nymphs based upon LD50 values. The extremes in sensitivity were 5.01 kilorads (krad) for early treated males and 13.09 krad for females treated late in the 5th instar. Wing deformities resulted from doses in the same range as those for mortality. Fifty percent of early treated males had wing deformities at a dose of 10.81 krad while a dose of 12.5 and 12.89 krad was necessary for 50% wing deformities in males and females, respectively, when treated late in the 5th instar. Fecundity and fertility were affected at lower dosages of radiation than for mortality. The treatment of both sexes produced the greatest effect. Fecundity was reduced by 50% at 1.22 krad, while 50% reduction in fertility occurred at about half that dose, or 0.66 krad. Somewhat greater doses were required when females alone were treated and mated with untreated males. In this case a 50% reduction occurred with 1.87 and 1.07 krad for fecundity and fertility, respectively. When males alone were treated, ED50 values were 2.24 and 1.58 krad for fecundity and fertility, respectively.

  12. Cross-validation Methodology between Ground and GPM Satellite-based Radar Rainfall Product over Dallas-Fort Worth (DFW) Metroplex

    NASA Astrophysics Data System (ADS)

    Chen, H.; Chandrasekar, V.; Biswas, S.

    2015-12-01

    Over the past two decades, a large number of rainfall products have been developed based on satellite, radar, and/or rain gauge observations. However, to produce optimal rainfall estimation for a given region is still challenging due to the space time variability of rainfall at many scales and the spatial and temporal sampling difference of different rainfall instruments. In order to produce high-resolution rainfall products for urban flash flood applications and improve the weather sensing capability in urban environment, the center for Collaborative Adaptive Sensing of the Atmosphere (CASA), in collaboration with National Weather Service (NWS) and North Central Texas Council of Governments (NCTCOG), has developed an urban radar remote sensing network in DFW Metroplex. DFW is the largest inland metropolitan area in the U.S., that experiences a wide range of natural weather hazards such as flash flood and hailstorms. The DFW urban remote sensing network, centered by the deployment of eight dual-polarization X-band radars and a NWS WSR-88DP radar, is expected to provide impacts-based warning and forecasts for benefit of the public safety and economy. High-resolution quantitative precipitation estimation (QPE) is one of the major goals of the development of this urban test bed. In addition to ground radar-based rainfall estimation, satellite-based rainfall products for this area are also of interest for this study. Typical example is the rainfall rate product produced by the Dual-frequency Precipitation Radar (DPR) onboard Global Precipitation Measurement (GPM) Core Observatory satellite. Therefore, cross-comparison between ground and space-based rainfall estimation is critical to building an optimal regional rainfall system, which can take advantages of the sampling differences of different sensors. This paper presents the real-time high-resolution QPE system developed for DFW urban radar network, which is based upon the combination of S-band WSR-88DP and X-band CASA radars. In addition, we focuses on the cross-comparison between rainfall estimation from this ground based QPE system and GPM rainfall products. The observations collected during the GPM satellite overpasses over DFW area will be used extensively in this study. Data alignment for better comparison will also be presented.

    The NASA Langley Research Center's Aircraft Vortex Spacing System (AVOSS) requires accurate winds and turbulence to determine aircraft wake vortex behavior near the ground. Volume 1 described the wind input and quality analysis process. This volume documents the data available during the period January 1998 through January 1999 and the partitioning and concatenation of files for time of day, turbulence, non duplication, cross wind profile quality and ceiling and visibility. It provides the resultant filtered files for the first three partitions as well as identification of ceiling/visibility conditions when they were below 5000 feet and 5 miles respectively. It also includes the wind profile quality flags to permit automatic selection of files for AVOSS application using selected ceiling/visibility and wind profile quality values and flags (or no flags).

    We evaluated day-of-week differences in mean concentrations of ozone (O3) precursors (nitric oxide NO), nitrogen oxides NOx, carbon monoxide CO, and volatile organic compounds VOCs at monitoring sites in 23 states comprising seven geographic focus areas over the period 1998- 2003. Data for VOC measurements were available for six metropolitan areas in five regions. We used Wednesdays to represent weekdays and Sundays to represent weekends; we also analyzed Saturdays. At many sites, NO, NOx, and CO mean concentrations decreased at all individual hours from 6:00 a.m. to 3:00 p.m. on Sundays compared with corresponding Wednesday means. Statistically significant (p 0.01) weekend decreases in ambient concentrations were observed for 92% of NOx sites, 89% of CO sites, and 23% of VOC sites. Nine-hour (6:00 a.m. to 3:00 p.m.) mean concentrations of NO, NOx, CO, and VOCs declined by 65, 49, 28, and 19%, respectively, from Wednesdays to Sundays (median site responses). Despite the large reductions in ambient NOx and moderate reductions in ambient CO and VOC concentrations on weekends, ozone and particulate matter (PM) nitrate did not exhibit large changes from weekdays to weekends. The median differences between Wednesday and Sunday mean ozone concentrations at all monitoring sites ranged from 3% higher on Sundays for peak 8-hr concentrations determined from all monitoring days to 3.8% lower on Sundays for peak 1-hr concentrations on extreme-ozone days. Eighty-three percent of the sites did not show statistically significant differences between Wednesday and weekend mean concentrations of peak ozone. Statistically significant weekend ozone decreases occurred at 6% of the sites and significant increases occurred at 11% of the sites. Average PM nitrate concentrations were 2.6% lower on Sundays than on Wednesdays. Statistically significant Sunday PM nitrate decreases occurred at one site and significant increases occurred at seven sites.

  2. Computer-model analysis of ground-water flow and simulated effects of contaminant remediation at Naval Weapons Industrial Reserve Plant, Dallas, Texas

    USGS Publications Warehouse

    Barker, Rene A.; Braun, Christopher L.

    2000-01-01

    In June 1993, the Department of the Navy, Southern Division Naval Facilities Engineering Command (SOUTHDIV), began a Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) of the Naval Weapons Industrial Reserve Plant (NWIRP) in north-central Texas. The RFI has found trichloroethene, dichloroethene, vinyl chloride, as well as chromium, lead, and other metallic residuum in the shallow alluvial aquifer underlying NWIRP. These findings and the possibility of on-site or off-site migration of contaminants prompted the need for a ground-water-flow model of the NWIRP area. The resulting U.S. Geological Survey (USGS) model: (1) defines aquifer properties, (2) computes water budgets, (3) delineates major flowpaths, and (4) simulates hydrologic effects of remediation activity. In addition to assisting with particle-tracking analyses, the calibrated model could support solute-transport modeling as well as help evaluate the effects of potential corrective action. The USGS model simulates steady-state and transient conditions of ground-water flow within a single model layer. The alluvial aquifer is within fluvial terrace deposits of Pleistocene age, which unconformably overlie the relatively impermeable Eagle Ford Shale of Late Cretaceous age. Over small distances and short periods, finer grained parts of the aquifer are separated hydraulically; however, most of the aquifer is connected circuitously through randomly distributed coarser grained sediments. The top of the underlying Eagle Ford Shale, a regional confining unit, is assumed to be the effective lower limit of ground-water circulation and chemical contamination. The calibrated steady-state model reproduces long-term average water levels within +5.1 or ?3.5 feet of those observed; the standard error of the estimate is 1.07 feet with a mean residual of 0.02 foot. Hydraulic conductivity values range from 0.75 to 7.5 feet per day, and average about 4 feet per day. Specific yield values range from 0.005 to 0.15 and average about 0.08. Simulated infiltration rates range from 0 to 2.5 inches per year, depending mostly on local patterns of ground cover. Computer simulation indicates that, as of December 31, 1998, remediation systems at NWIRP were removing 7,375 cubic feet of water per day from the alluvial aquifer, with 3,050 cubic feet per day coming from aquifer storage. The resulting drawdown prevented 1,800 cubic feet per day of ground water from discharging into Cottonwood Bay, as well as inducing another 1,325 cubic feet per day into the aquifer from the bay. An additional 1,200 cubic feet of water per day (compared to pre-remediation conditions) was prevented from discharging into the west lagoon, east lagoon, Mountain Creek Lake, and Mountain Creek swale. Particle-tracking simulations, assuming an aquifer porosity of 0.15, were made to delineate flowpath patterns, or contaminant ?capture zones,? resulting from 2.5- and 5-year periods of remediation activity at NWIRP. The resulting flowlines indicate three such zones, or areas from which ground water is simulated to have been removed during July 1996?December 1998, as well as extended areas from which ground water would be removed during the next 2.5 years (January 1999?June 2001). Simulation indicates that, as of December 31, 1998, the recovery trench was intercepting about 827 cubic feet per day of ground water that?without the trench?would have discharged into Cottonwood Bay. During this time, the trench is simulated to have removed about 3,221 cubic feet per day of water from the aquifer, with about 934 cubic feet per day (29 percent) coming from the south (Cottonwood Bay) side of the trench.

  16. Delivery of Mental Health Care in a Large Disaster Shelter.

    PubMed

    North, Carol S; King, Richard V; Fowler, Raymond L; Kucmierz, Rita; Wade, Jess D; Hogan, Dave; Carlo, John T

    2015-08-01

    Large numbers of evacuees arrived in Dallas, Texas, from Hurricanes Katrina and Rita just 3 weeks apart in 2005 and from Hurricanes Gustav and Ike just 3 weeks apart again in 2008. The Dallas community needed to locate, organize, and manage the response to provide shelter and health care with locally available resources. With each successive hurricane, disaster response leaders applied many lessons learned from prior operations to become more efficient and effective in the provision of services. Mental health services proved to be an essential component. From these experiences, a set of operating guidelines for large evacuee shelter mental health services in Dallas was developed, with involvement of key stakeholders. A generic description of the processes and procedures used in Dallas that highlights the important concepts, key considerations, and organizational steps was then created for potential adaptation by other communities.

  6. Engaging in large-scale digital health technologies and services. What factors hinder recruitment?

    PubMed

    O'Connor, Siobhan; Mair, Frances S; McGee-Lennon, Marilyn; Bouamrane, Matt-Mouley; O'Donnell, Kate

    2015-01-01

    Implementing consumer oriented digital health products and services at scale is challenging and a range of barriers to reaching and recruiting users to these types of solutions can be encountered. This paper describes the experience of implementers with the rollout of the Delivering Assisted Living Lifestyles at Scale (dallas) programme. The findings are based on qualitative analysis of baseline and midpoint interviews and project documentation. Eight main themes emerged as key factors which hindered participation. These include how the dallas programme was designed and operationalised, constraints imposed by partnerships, technology, branding, and recruitment strategies, as well as challenges with the development cycle and organisational culture.

  7. Role of adipose-derived stem cells in chronic cutaneous wound healing.

    PubMed

    Caruana, Giorgia; Bertozzi, Nicolò; Boschi, Elena; Pio Grieco, Michele; Grignaffini, Eugenio; Raposio, Edoardo

    2015-01-01

    Le ulcere cutanee croniche colpiscono circa l’1% della popolazione adulta e il 3.6% della popolazione con più di sessantacinque anni di età. Per quanto riguarda l’impegno finanziario per la terapia delle ulcere cutanee, questo è pari a sette miliardi di euro annui a livello mondiale. Le cellule staminali mesenchimali prelevate da lipoaspirato (ASCs) rappresentano una delle frontiere più promettenti della medicina rigenerativa. Diversi studi hanno, infatti, dimostrato l’efficacia terapeutica di questa popolazione di cellule staminali nel trattamento delle ulcere cutanee croniche. Le ASCs hanno caratteristiche morfologiche e funzionali paragonabili alle cellule staminali del midollo osseo (BMSCs), tuttavia se ne differenziano per la maggiore facilità di prelievo e isolamento, e per il loro più cospicuo numero. È, infatti, sufficiente eseguire una liposuzione tradizionale e in seguito utilizzare metodiche d’isolamento appropriate per ottenere un pellet di ASCs pronte per essere innestate nel fondo e nel margine dell’ulcera cutanea, al fine di promuoverne la guarigione. Diversi sono i protocolli d’isolamento; i più diffusi prevedono complicati e lunghi procedimenti, caratterizzati dal susseguirsi di differenti prodotti sia chimici sia biologici, i quali sono non solo costosi ma anche potenzialmente pericolosi. Il nostro protocollo d’isolamento richiede solo 15’ e prevede che il lipoaspirato sia prima sistemato in uno shaker cellulare e successivamente in una centrifuga così da ottenere le ASCs richieste per la terapia. L’uso delle ASCs si è rivelato una risorsa preziosa per la terapia delle ulcere cutanee croniche, accelerando significativamente il processo di guarigione e la rigenerazione dei tessuti; con protocolli d’isolamento efficaci e semplificati, il loro utilizzo routinario risulta essere facilitato.

  3. An Operational Computational Terminal Area PBL Prediction System

    NASA Technical Reports Server (NTRS)

    Lin, Yuh-Lang; Kaplan, Michael L.

    1998-01-01

    There are two fundamental goals of this research project which are listed here in terms of priority, i.e., a primary and secondary goal. The first and primary goal is to develop a prognostic system which could satisfy the operational weather prediction requirements of the meteorological subsystem within the Aircraft Vortex Spacing System (AVOSS), i.e., an operational computational Terminal Area PBL Prediction System (TAPPS). The second goal is to perform indepth diagnostic analyses of the meteorological conditions during the special wake vortex deployments at Memphis and Dallas during August 95 and September 97, respectively. These two goals are interdependent because a thorough understanding of the atmospheric dynamical processes which produced the unique meteorology during the Memphis and Dallas deployments will help us design a prognostic system for the planetary boundary layer (PBL) which could be utilized to support the meteorological subsystem within AVOSS. Concerning the primary goal, TAPPS Stage 2 was tested on the Memphis data and is about to be tested on the Dallas case studies. Furthermore benchmark tests have been undertaken to select the appropriate platform to run TAPPS in real time in support of the DFW AVOSS system. In addition, a technique to improve the initial data over the region surrounding Dallas was also tested and modified for potential operational use in TAPPS. The secondary goal involved several sensitivity simulations and comparisons to Memphis observational data sets in an effort to diagnose what specific atmospheric phenomena where occurring which may have impacted the dynamics of atmospheric wake vortices.
