    2001-03-01

    From analyzing nine months of airglow imaging observations of atmospheric gravity waves (AGWs) over Adelaide, Australia (35°S) [Walterscheid et al., 1999] have proposed that many of the quasi-monochromatic waves seen in the images were primarily thermally ducted. Here are presented 15 months of observations, from February 1996 to May 1997, for AGW frequency and propagation direction from a northern latitude site, Urbana Illinois (40°N). As Adelaide, Urbana is geographically distant from large orographic features. Similar to what was found in Adelaide, the AGWs seem to originate from a preferred location during the time period around summer solstice. In conjunction with these airglow data there exists MF radar data to provide winds in the 90 km region and near-simultaneous lidar data which provide a temperature climatology. The temperature data have previously been analyzed by States and Gardner [2000]. The temperature and wind data are used here in a full wave model analysis to determine the characteristics of the wave ducting and wave reflection during the 15 month observation period. This model analysis is applied to this and another existing data set recently described by Nakamura et al. [1999]. It is shown that the existence of a thermal duct around summer solstice can plausibly account for our observations. However, the characteristics of the thermal duct and the ability of waves to be ducted is also greatly dependent on the characteristics of the background wind. A simple model is constructed to simulate the trapping of these waves by such a duct. It is suggested that the waves seen over Urbana originate no more than a few thousand kilometers from the observation site.

    The design, development, and first observations of a high power meteor-radar system located near Urbana, Illinois are described. The roughly five-fold increase in usable echo rate compared to other facilities, along with automated digital data processing and interferometry measurement of echo arrival angles, permits unsurpassed observations of tidal structure and shorter period waves. Such observations are discussed. The technique of using echo decay rates to infer density and scale height and the method of inferring wind shear from radial acceleration are examined. An original experiment to test a theory of the Delta-region winter anomaly is presented.

    1988-01-01

    During 13 nights of Rayleigh lidar measurements at Urbana, Ill. in 1984 to 1986, thirty-six quasi-monochromatic gravity waves were observed in the 35 to 50 km altitude region of the stratosphere. The characteristics of the waves are compared with other lidar and radar measurements of gravity waves and the theoretical models of wave saturation and dissipation phenomena. The measured vertical wavelengths ranged from 2 to 11.5 km and the measured vertical phase velocities ranged from 10 to 85 cm/s. The vertical wavelengths and vertical phase velocities were used to infer observed wave periods which ranged from 100 to 1000 min and horizontal wavelengths which ranged from 70 to 2000 km. Dominant wave activity was found at vertical wavelengths between 2 to 4 km and 7 to 10 km. No significant seasonal variations were evident in the observed parameters. Vertical and horizontal wavelengths showed a clear tendency to increase with wave periods, which is consistent with recent sodium lidar studies of quasi-monochromatic waves near the mesopause. An average amplitude growth length of 20.9 km for the rms wind perturbations was estimated from the data. Kinetic energy density associated with the waves decreased with height, suggesting that waves in this altitude region were subject to dissipation or saturation effects.

    Boneyard Creek—which drains an urbanized watershed in the cities of Champaign and Urbana, Illinois, including part of the University of Illinois at Urbana-Champaign (UIUC) campus—has historically been prone to flooding. Using the Stormwater Management Model (SWMM), a hydrologic and hydraulic model of Boneyard Creek was developed for the design of the projects making up the first phase of a long-term plan for flood control on Boneyard Creek, and the construction of the projects was completed in May 2003. The U.S. Geological Survey, in cooperation with the Cities of Champaign and Urbana and UIUC, installed and operated stream and rain gages in order to obtain data for evaluation of the design-model simulations. In this study, design-model simulations were evaluated by using observed postconstruction precipitation and peak-discharge data. Between May 2003 and September 2008, five high-flow events on Boneyard Creek satisfied the study criterion. The five events were simulated with the design model by using observed precipitation. The simulations were run with two different values of the parameter controlling the soil moisture at the beginning of the storms and two different ways of spatially distributing the precipitation, making a total of four simulation scenarios. The simulated and observed peak discharges and stages were compared at gaged locations along the Creek. The discharge at one of these locations was deemed to be critical for evaluating the design model. The uncertainty of the measured peak discharge was also estimated at the critical location with a method based on linear regression of the stage and discharge relation, an estimate of the uncertainty of the acoustic Doppler velocity meter measurements, and the uncertainty of the stage measurements. For four of the five events, the simulated peak discharges lie within the 95-percent confidence interval of the observed peak discharges at the critical location; the fifth was just outside the upper end of

    A visit was made to the Frit Bagging Operation at the Chi-Vit Corporation located at Urbana, Ohio for the purpose of examining methods used at this facility to control worker exposure to hazardous materials during the production of various frits. Frit was the basic material for porcelain enamel used in major appliance finishes. The three major raw materials used to produce frit were soda-ash, borax, and silica-flour. In the manufacturing area batching, mixing, smelting, and bagging take place. All new employees were given a preemployment physical. An annual hearing evaluation was performed for all workers. Ventilation was provided throughout the operation. Each weight bin in the batching area was equipped with exhaust ventilation. The frit was moved by a vibration conveyor between smelter and bagger and passed under three exhaust hoods to remove airborne dust during this last portion of this transfer. A small capture hood at the packer unit removed airborne dust generated as material falls from the slide gate to the packer spout. The disposal of the bags was carried out in a very satisfactory manner. The author concludes that the controls used provided an exemplary work environment. The author recommends that an in-depth survey be conducted at this site.

    Environmental radioactivity monitoring includes the determination of radionuclides in foods since they are an important way of intake of radionuclides to the human organism. Moreover, knowledge of the levels of radionuclides in foodstuffs will inform about the environmental radioactivity background permitting to control possible contamination due to human activity, such as agriculture activity, nuclear power plants or other radioactive facilities. The Environmental Radioactivity Laboratory (LRA) at the Universitat Politècnica de València (UPV) performs measurements on representative foods from all over the Comunidad Valenciana (CV). Those measurements are part of several monitoring programs promoted by the Generalitat Valenciana. A total of 2200 samples of fruits, cereals, vegetables, milk, meat, eggs and fish coming from markets, agricultural cooperatives or small producers have been analyzed. A gamma-ray spectrometry analysis has been performed in all samples. It has been detected 40K in all samples, 7Be in some of them. Radiochemical separation of 90Sr has been carried out in some of the samples collected, mainly orange and lettuce. Samples of lettuce and chard collected following Fukushima Nuclear Power Plant (NPP) accident present activity concentration of 131I (0.10-1.51 Bq kg-1). In this paper, a review of the data obtained at the 1991-2013 period in the framework of the development of the Environmental monitoring program is presented.

    The Health Occupations Teacher Education Program at the University of Illinois, Urbana-Champaign, U.S.A. has been shown to be a viable and productive model for the preparation of health occupations teacher for both traditional and non-traditional educational settings. Since 1971 the undergraduate program has grown from twelve students to 30 students on-campus, with more than two hundred students in the extramural and part-time programs. Recruitment has been accomplished through professional association meetings, journals and personal contacts. More recently, persons have heard of the program through extramural classes and from students, graduates or University personnel who have become familiar with the program. Program development has been effected through the "capstone" concept, which allows for transfer of technical credit in one's specialty, capped by teacher education courses and concentrated courses to enhance one's expertise in the teaching role. Courses developed by the HOTEP faculty are based on perceived student needs, and were designed as both integrative and collaborative courses to be taken with other health care practitioners and teachers. Evaluation procedures have shown the health occupations teacher education program to be effective in preparing graduates for their predicted roles. The numbers of new students, kinds of health practitioners, and numbers of graduates have increased steadily. Implementation of courses into the Health Occupations Teacher Education Program curriculum has been gradual, so that the undergraduate core of courses is now considered to be nearly complete. Much curriculum planning has already been completed on the master's program, from which some students have already graduated. A doctoral program is also open to those ready for this level of preparation. More time and effort needs to be and will be expended on courses for the master's and doctoral level programs being developed. This health occupations teacher education has

    Optimum natural resource management and biodiversity conservation are desirable goals. These, however, often exclude each other, since maximum economic benefits have promoted drastic reductions in biodiversity throughout the world. This dilemma confronts local stakeholders, who usually go for maximizing economic inputs, whereas other social (e.g., academic) sectors are favor conservation practices. In this paper we describe the way two scientific approaches--landscape and participatory research--were used to develop sound and durable land use scenarios. These two approaches included expert knowledge of both social and environmental conditions in indigenous communities. Our major emphasis was given to detect spatially explicit land use scenarios and capacity building in order to construct a decision support system operated by stakeholders of the Comunidad Indigena de Nuevo San Juan Parangaricutiro in Mexico. The system for decision-making was fed with data from inventories of both abiotic and biotic biodiversity components. All research, implementation, and monitoring activities were conducted in close collaboration with members of the indigenous community. As a major result we obtained a number of forest alternative uses that favor emerging markets and make this indigenous community less dependent on a single market. Furthermore, skilled members of the community are now running the automated system for decision-making. In conclusion, our results were better expressed as products with direct benefits in local livelihoods rather than pure academic outputs.

    Resumen:En este artículo presentamos el proyecto de capacitación llevado a cabo en comunidades de la sierra y costa de Oaxaca, México, desde 1991, por el Centro de Capacitación Integral para Promotores Comunitarios (CECIPROC). La decisión de hacer este trabajo en Oaxaca responde a que ese estado ocupa uno de los primeros lugares de marginación y de desnutrición en menores de 5 años. El objetivo es describir un modelo de capacitación y compartir parte de las experiencias derivadas, tanto del modelo como del trabajo realizado en las distintas áreas (nutrición y alimentación, salud comunitaria, ecología y etnobotánica, y educación y organización), por promotores mujeres y hombres en sus comunidades.La experiencia obtenida en 24 años muestra la factibilidad técnica y social del proyecto en el ámbito de la salud, el reconocimiento social del proyecto del CECIPROC como un organismo civil que ha aportado alternativas como solución a la problemática de salud, el hacer suyo el proyecto por algunos promotores y los diferentes obstáculos a los que se ha enfrentado. Enfatizamos el hecho de que la situación socioeconómica y política prevaleciente en el estado de Oaxaca es una limitante para el buen desarrollo de los programas colectivos de salud, e insistimos en la necesidad de compartir nuestras experiencias para que puedan ser utilizadas en la planificación y ejecución de otros proyectos.

    RESUMEN Introducción Las infecciones del tracto urinario (ITU) son frecuentes en la comunidad. Sin embargo, la información de aislamientos resistentes en este contexto es limitada en Latinoamérica. Este estudio tiene como objetivo determinar la prevalencia y los factores de riesgo asociados con ITU de inicio en la comunidad (ITU-IC) causadas por Escherichia coli productor de betalactamasas de espectro extendido (BLEE) en Colombia. Materiales y métodos Entre agosto y diciembre de 2011 se realizó un estudio de casos y controles en 3 instituciones de salud de tercer nivel en Colombia. Se invitó a participar a todos los pacientes admitidos a urgencias con diagnóstico probable de ITU-IC, y se les pidió una muestra de orina. En los aislamien-tos de E. coli se realizaron pruebas confirmatorias para BLEE, susceptibilidad antibiótica, caracterización molecular (PCR en tiempo real para genes bla, repetitive element palindromic PCR [rep-PCR], multilocus sequence typing [MLST] y factores de virulencia por PCR). Se obtuvo información clínica y epidemiológica, y posteriormente se realizó el análisis estadístico. Resultados De los 2.124 pacientes seleccionados, 629 tuvieron un urocultivo positivo, en 431 de estos se aisló E. coli, 54 fueron positivos para BLEE y 29 correspondieron a CTX-M-15. La mayoría de los aislamientos de E. coli productor de BLEE fueron sensibles a ertapenem, fosfomicina y amikacina. La ITU complicada se asoció fuertemente con infecciones por E. coli productor de BLEE (OR = 3,89; IC 95%: 1,10–13,89; p = 0,03). E. coli productor de CTX-M-15 mostró 10 electroferotipos diferentes; de estos, el 65% correspondieron al ST131. La mayoría de estos aislamientos tuvieron 8 de los 9 factores de virulencia analizados. Discusión E. coli portador del gen blaCTX-M-15 asociado al ST131 sigue siendo frecuente en Colombia. La presencia de ITU-IC complicada aumenta el riesgo de tener E. coli productor de BLEE, lo cual debe tenerse en cuenta para ofrecer

    A retrospective, population-based registry was established in the Comunidad of Madrid, Spain (total population: 4,780,572; under age 15: 1,105,243) to investigate the epidemiology of Type 1 (insulin-dependent) diabetes mellitus. Included were all cases diagnosed with diabetes between 1985 and 1988, with age onset less than 15 years, and using insulin at discharge from hospital. Using the capture-recapture method employing hospital records as the primary source and membership files of the Spanish Diabetic Association as the secondary source, the ascertainment was 90%. The overall annual incidence was estimated to be 11.3/100,000 (Poison 95% confidence interval: 10.3-12.4). There was no temporal increase in incidence, nor was there a significant sex difference in incidence rates, either overall or by year. The seasonal onset pattern showed the highest incidence in winter (December-February) and lowest in summer (June-August) (r = 7.36, p less than 0.05). The age-adjusted (world standard) incidence of 10.9/100,000 was inconsistent with the hypothesis of a north-south gradient in diabetes risk.

    Estudio realizado desde el enfoque de la salutogénesis que pretende determinar el sentido de coherencia (SOC) en jóvenes presos de la Comunidad Valenciana en España y elaborar un mapa de activos para la salud dirigido a promover la salud en esta población. Se utilizó el test "SOC-13" y un cuestionario de preguntas abiertas elaboradoad hoc, el cual autocompletaron los internos de 18 a 22 años de edad, de los tres centros penitenciarios de la región. Participaron 124 jóvenes varones (ya que no había ninguna mujer) y se recogieron variables sociodemográficas y penitenciarias. En el análisis cuantitativo, las variables categóricas se expresaron como frecuencias absolutas y relativas; y las cuantitativas, mediante medias con intervalos de confianza (IC) al 95%. Se realizó un estudio comparativo bivariante, utilizando las siguientes pruebas: Studentt-test, análisis de variación (ANOVA), Wilcoxon y Ji-cuadrado. Del cuestionario de preguntas abiertas, se realizó un análisis cualitativo descriptivo temático de los activos identificados, clasificándolos en: internos (recursos personales, en relación con los demás y capacidad para realizar comportamientos saludables) y externos (personas, grupos, instituciones y espacios físicos, situados tanto dentro como fuera de prisión). La edad media fue de 21,1 años (IC 95%: 20,8-21,3); y el SOC de 52,4 (IC 95%: 50,5-54,3), de entre un valor mínimo de 13 y máximo de 91 para la prueba. Los internos del centro penitenciario que ofrecía más actividades escolares y deportivas obtuvieron una puntuación mayor en la dimensión de significatividad del SOC (p= 0,024), y los internos inmigrantes presentaron un SOC superior (p= 0,037) a los españoles, en los tres centros. Los jóvenes identificaron los activos internos que cualitativamente se vinculan con las dimensiones de comprensibilidad, manejabilidad y significatividad del SOC; y los activos externos, sobre todo los amigos, familiares y espacios relacionados con

    A method for calibrating data obtained by the Urban sodium lidar system is presented. First, an expression relating the number of photocounts originating from a specific altitude range to the soodium concentration is developed. This relation is then simplified by normalizing the sodium photocounts with photocounts originating from the Rayleigh region of the atmosphere. To evaluate the calibration expression, the laser linewidth must be known. Therefore, a method for measuring the laser linewidth using a Fabry-Perot interferometer is given. The laser linewidth was found to be 6 + or - 2.5 pm. Problems due to photomultiplier tube overloading are discussed. Finally, calibrated data is presented. The sodium column abundance exhibits something close to a sinusoidal variation throughout the year with the winter months showing an enhancement of a factor of 5 to 7 over the summer months.

    A coherent scatter radar system was synthesized and several hundred hours of echo power and line of sight velocity data obtained. The coherent scatter radar utilizes a diode array and components from meteor radar. The receiving system permits a time resolution of one minute in the data. Echo power from the D region shows a high degree of variability from day to day. Examples of changes in power level at shorter time scales are observed. Velocity data show the existence of gravity waves and occasionally exhibit vertical standing wave characteristics.

    The design, interfacing, testing, and operation of a preprocessor to increase the altitude and temporal resolution of the present coherent-scatter system are described. This system upgrade requires an increase in the data collection rate. Replacing the present, relatively slow, ADC with two high speed ADCs achieves the increased echo sampling rate desired. To stay within the capabilities of the main computer's I/O and processing rate the data must be reduced before transfer to the main computer. Thus the preprocessor also coherently integrates the data before transfer.

    For more than 15 years lidar systems have been used to study the chemistry and dynamics of the mesospheric sodium layer. Because the layer is an excellent tracer of atmospheric wave motions, sodium lidar has proven to be particularly useful for studying the influence of gravity waves and tides on mesospheric dynamics. These waves, which originate in the troposphere and stratosphere, propagate through the mesosphere and dissipate their energy near the mesopause making important contributions to the momentum and turbulence budget in this region of the atmosphere. Recently, the sodium lidar was modified for daytime operation so that wave phenomena and chemical effects could be monitored throughout the complete diurnal cycle. The results of continuous 24 hour lidar observations of the sodium layer structure are presented alond with measurement of the semidiurnal tidal winds.

    Objetivo: Valorar las características antropométricas y la satisfacción con la propia imagen corporal en un grupo de estudiantes universitarios. Material y métodos: Se estudiaron 64 universitarios entre 21 y 25 años, 36 mujeres y 28 hombres. Se valoró la composición corporal mediante datos antropométricos y bioimpedanciometría. La satisfacción con la propia imagen corporal se valoró con una puntuación de 0 a 10. Resultados: El IMC medio fue de 21,95 y la masa grasa 12,15 ± 5,27 Kg, siendo esta mayor en mujeres. El grado de satisfacción con la imagen corporal fue alto, con una puntuación de 7,15 + 1,15 sobre 10 y solo 3 participantes se valoraron con menos de 5 puntos. No hubo diferencias entre ambos sexos ni se observó una correlación entre la autovaloración y los resultados antropométricos en el grupo total, aunque sí se ha observado una relación inversa entre el grado de satisfacción y el IMC (r = - 0,52), y no tan marcada con el porcentaje de grasa corporal (r = - 0,3) en el grupo de mujeres. Conclusiones: Las características antropométricas de la población estudiada son adecuadas, lo que se refleja en un alto grado de satisfacción con la propia imagen corporal. Sin embargo, en las mujeres hay una cierta tendencia a infravalorarse a medida que aumenta el valor del IMC, que no es tan marcada respecto al aumento de porcentaje de masa grasa, a pesar de que este último valor debería a priori reflejar más fielmente la imagen corporal real.

    ORAU conducted confirmatory survey activities within the NRL at the University during the week of May 7, 2012. The survey activities included visual inspections/ assessments, surface activity measurements, and volumetric concrete sampling activities. During the course of the confirmatory activities, ORAU noted several issues with the survey-for-release activities performed at the University. Issues included inconsistencies with: survey unit classifications were not designated according to Multi-Agency Radiation Survey and Site Investigation Manual guidance; survey instrument calibrations were not representative of the radionuclides of concern; calculations for instrumentation detection capabilities did not align with the release criteria discussed in the licensee’s survey guidance documents; total surface activity measurements were in excess of the release criteria; and Co-60 and Eu-152 concentrations in the confirmatory concrete samples were above their respective guidelines. Based on the significant programmatic issues identified, ORAU cannot independently conclude that the NRL satisfied the requirements and limits for release of materials without radiological restrictions.

    The ThermoElectric-driven Liquid-metal plasma-facing Structures (TELS) device is a gas-puff driven, theta pinched, transient plasma source used to simulate extreme events incident on materials in the edge and divertor regions of a tokamak plasma. Previous work has shown that in its current form, TELS can bombard a target with a peak energy of 0.08 MJ m-2 over a 0.15 ms pulse, leading to a total heat flux of 0.5 GW m-2. While these values are sufficient to mimic Type 1 ELMs in smaller devices, the plasma energy of TELS must be improved by a factor of greater than two to adequately simulate larger-scale Type 1 ELMs. It is for this reason that modifications to the existing TELS device have been proposed in the form of developing a compact toroid (CT) injector since the new self-contained structure allows for higher densities and energies delivered onto a target. The new setup will use a bias field, generating a peak magnetic field greater than 0.1 T and a peak magnetic flux greater than 2 mWb, surrounding the existing plasma gun arrangement to create the CT and the existing theta pinch to compress and translate the plasmoid. Preliminary results and analyses are presented and discussed in relationship to interactions with both solid and liquid metal targets. Supported by DOE Grant DE-SC0008587.

  10. The Determination of the Geometries of Multiple-Element Airfoils Optimized for Maximum Lift Coefficient. Ph.D. Thesis - Illinois Univ., Urbana

    NASA Technical Reports Server (NTRS)

    Chen, A. W.

    1971-01-01

    Optimum airfoils in the sense of maximum lift coefficient are obtained by a newly developed method. The maximum lift coefficient is achieved by requiring that the turbulent skin friction be zero in the pressure rise region on the upper surface. Under this constraint, the pressure distribution is optimized. The optimum pressure distribution consists of a uniform stagnation pressure on the lower surface, a uniform minimum pressure on the upper surface immediately downstream of the front stagnation point followed by a Stratford zero skin friction pressure rise. When multiple-element airfoils are under consideration, this optimum pressure distribution appears on every element. The parameters used to specify the pressure distribution on each element are the Reynolds number and the normalized trailing edge velocity. The newly developed method of design computes the velocity distribution on a given airfoil and modifies the airfoil contour in a systematic manner until the desired velocity distribution is achieved. There are no limitations on how many elements the airfoil to be designed can have.

    The Recreovia program provides free physical activity (PA) classes in public spaces in Bogota, Colombia. The purpose of this study was to assess the effectiveness of the Recreovia program in increasing PA among users of nine parks in Bogota. This study was a natural experiment conducted between 2013 and 2015 in Bogota. Community members and park users living nearby three groups of parks were compared: Group 1 were parks implementing new Recreovias (n=3), Group 2 were control parks (n=3) without Recreovias, and Group 3 were parks with existing Recreovías. Individuals in the "intervention" group were exposed to newly implemented Recreovia programs in parks near their homes. Measurements were collected at baseline and 6-8months after the intervention started. A total of 1533 participants were enrolled in the study: 501 for the existing Recreovias (included in a cross-sectional assessment) and 1032 participants (from the new Recreovias and control parks) included in the cross-sectional and pre-post study. Most participants were low income females. Twenty-three percent of the intervention group started participating in the program. Users of existing Recreovias were significantly more active and less likely to be overweight/obese compared to new Recreovia users at baseline. No changes on PA were found when comparing the intervention and control groups. Recreovias may have potential for increasing PA at the population level in urban areas given their rapid scalability, the higher levels of PA observed among program users, and its potential to reach women, low-income, less educated populations, and the overweight and obese.

  15. A FORTRAN program to implement the method of finite elements to compute regional and residual anomalies from gravity data

    NASA Astrophysics Data System (ADS)

    Agarwal, B. N. P.; Srivastava, Shalivahan

    2010-07-01

    In view of the several publications on the application of the Finite Element Method (FEM) to compute regional gravity anomaly involving only 8 nodes on the periphery of a rectangular map, we present an interactive FORTRAN program, FEAODD.FOR, for wider applicability of the technique. A brief description of the theory of FEM is presented for the sake of completeness. The efficacy of the program has been demonstrated by analyzing the gravity anomaly over Salt dome, South Houston, USA using two differently oriented rectangular blocks and over chromite deposits, Camaguey, Cuba. The analyses over two sets of data reveal that the outline of the ore body/structure matches well with the maxima of the residuals. Further, the data analyses over South Houston, USA, have revealed that though the broad regional trend remains the same for both the blocks, the magnitudes of the residual anomalies differ approximately by 25% of the magnitude as obtained from previous studies.

  14. Studies in neotropical paleobotany. XIV. A palynoflora from the middle Eocene Saramaguacan formation of Cuba

    USGS Publications Warehouse

    Graham, A.; Cozadd, D.; Areces-Mallea, A.; Frederiksen, N.O.

    2000-01-01

    An assemblage of 46 fossil pollen and spore types is described from a core drilled through the middle Eocene Saramaguacan Formation, Camaguey Province, eastern Cuba. Many of the specimens represent unidentified or extinct taxa but several can be identified to family (Palmae, Bombacaceae, Gramineae, Moraceae, Myrtaceae) and some to genus (Pteris, Crudia, Lymingtonia?). The paleo-climate was warm-temperate to subtropical which is consistent with other floras in the region of comparable age and with the global paleotemperature curve. Older plate tectonic models show a variety of locations for proto-Cuba during Late Cretaceous and later times, including along the norther coast of South America. More recent models depict western and central Cuba as two separate parts until the Eocene, and eastern Cuba (joined to northern Hispaniola) docking to central Cuba also in the Eocene. All fragments are part of the North American Plate and none were directly connected with northern South America in late Mesozoic or Cenozoic time. The Saramaguacan flora supports this model because the assemblage is distinctly North American in affinities, with only one type (Retimonocolpites type 1) found elsewhere only in South America.

  15. Solar flare ionization in the mesosphere observed by coherent-scatter radar

    NASA Technical Reports Server (NTRS)

    Parker, J. W.; Bowhill, S. A.

    1986-01-01

    The coherent-scatter technique, as used with the Urbana radar, is able to measure relative changes in electron density at one altitude during the progress of a solar flare when that altitude contains a statistically steady turbulent layer. This work describes the analysis of Urbana coherent-scatter data from the times of 13 solar flares in the period from 1978 to 1983. Previous methods of measuring electron density changes in the D-region are summarized. Models of X-ray spectra, photoionization rates, and ion-recombination reaction schemes are reviewed. The coherent-scatter technique is briefly described, and a model is developed which relates changes in scattered power to changes in electron density. An analysis technique is developed using X-ray flux data from geostationary satellites and coherent scatter data from the Urbana radar which empirically distinguishes between proposed D-region ion-chemical schemes, and estimates the nonflare ion-pair production rate.

    SULTATS La prévalence globale des fumeurs actuels est de 28,1%. Près de la moitié des personnes âgées ont fumé à un moment quelconque dans leur vie et parmi celles-ci, 44% ont cessé de fumer. Les personnes âgées ont cessé de fumer lorsqu’elles en ont perçu les effets négatifs sur la santé. Le fait d’avoir au moins une maladie chronique et de souffrir d’une incapacité fonctionnelle ont augmenté d’une façon significative les chances d’arrêt du tabagisme. De plus, le fait d’être un ancien fumeur a augmenté le risque d’admission hospitalière. CONCLUSIONS Cette étude est d’une importance particulière car ses implications s’élargissent à des collectivités à faibles revenus similaires et chez les réfugiés dans la région ainsi qu’ailleurs. Il est nécessaire que les responsables de la santé publique fassent un effort plus concerté pour cibler les personnes âgées comme groupe en vue d’interventions d’arrêt du tabagisme, d’autant plus que les avantages en matière de mortalité et de santé ont aujourd’hui été bien documentés. RESUMEN OBJETIVOS Investigar los tipos de hábito tabáquico en una población de personas ancianas, de bajos ingresos y determinar los factores pronósticos del abandono del hábito. Asimismo, se analizó la importancia del tabaquismo en relación con otros factores de riesgo de hospitalización. DISEÑO Los datos formaban parte de un estudio de salud urbana de 740 personas de ≥60 años de edad, en tres comunidades suburbanas de bajo estrato socioeconómico en Beirut, una de las cuales era un campo de refugiados. Se administró una entrevista estructurada que aportaba amplia información social y sanitaria. RESULTADOS La prevalencia global de fumadores fue de 28,1%. Casi la mitad de las personas ancianas había sido fumadora en algún momento y 44% habían abandonado el tabaquismo. Estas personas abandonaron el hábito tabáquico cuando tuvieron repercusiones negativas sobre su salud. La

    2014-12-01

    The Continuously Operating Caribbean Observational Network (COCONet) is a National Science Foundation (NSF) funded infrastructure project that stretches across the circum-Caribbean to include Central America and the northern portions of South America. Its objective is to develop a large-scale network of geodetic and atmospheric infrastructure to support a broad range of geoscience and atmospheric investigations and enable research on process-oriented science with direct relevance to geo-hazards. The network includes over 60 new and refurbished continuously operating Global Positioning System (GPS) and surface meterology stations. It will also include data from at least 60 existing stations that are being operated by one of our more than 40 regional partners. As COCONet approaches the completion of its build-out phase, it is appropriate to evaluate the activities associated with the project that facilitate capacity building. These activities include three workshops to solicit feedback from regional partners regarding science objectives, station location, and long-term network operation. COCONet graduate research fellowships have been used to support nine students, with seven from countries within the COCONet footprint. The establishment of three regional data and archive centers to foster access to data and promote free and open data standards. Lastly, two Pan American Advanced Studies Institute (PASI) workshops on topics that are central to the main goals of COCONet were also organized to engage early career scientists who are interested in working on topics that are directly relevant to the region. Perhaps the most significant effort on expanding capacity in the region is the recent deployment of a station in Camaguey, Cuba with full support from both the U.S. and Cuban governments. This presentation summarizes the activities of the COCONet project to enhance and support both the human resource development and technical capabilities within the region.

    Introducción: la estimación de la isonimia es una herramienta importante en la determinación de la estructura genética de las comunidades puesto que su magnitud es aproximadamente igual a cuatro veces el coeficiente de endogamia FST. Métodos: se analizaron los apellidos registrados en la base de datos de 26 comunidades del Tribunal Supremo Electoral de Honduras. Se calculó la isonimia aleatoria dentro de cada comunidad y en el total, así como diversos parámetros comunes asociados. Se determinaron las distancias genéticas de Lasker a partir de la isonimia calculada entre pares de comunidades. Resultados: se encontraron valores relativamente altos de isonimia aleatoria en comparación con otras comunidades rurales. Adicionalmente, se observaron distancias genéticas relativamente cortas y se encontró una correlación positiva con las distancias geográficas. Conclusiones: los resultados son congruentes con el aislamiento histórico de las comunidades y reciente tendencia a la homogenización por las altas tasas de migración masculina intercomunitaria. Las características de la población garífuna la hacen propicia para la realización de estudios destinados a la búsqueda de genes de susceptibilidad relacionados con enfermedades de herencia compleja.

    Introducción: el método de isonimia ha sido utilizado ampliamente para la determinación de la estructura genética aproximada de las poblaciones humanas. El objetivo del estudio fue evaluar la magnitud del aislamiento genético y las costumbres endogámicas en 57 comunidades de tres municipios rurales de Honduras utilizando las técnicas de isonimia. Métodos: se utilizó el listado de 408 apellidos diferentes utilizados por 20 712 votantes registrados en el Tribunal Supremo Electoral, que residen en las 57 comunidades estudiadas. Para cada comunidad se calcularon los valores de la isonimia aleatoria (IR), no aleatoria (IN) y total (IT) con el fin de evaluar los coeficientes de consanguinidad FST, FIS y FIT. Resultados: se encontró alta consanguinidad debido a aislamiento y a costumbres endogámicas en muchas comunidades. En los tres municipios se observó desviación significativa del comportamiento exógamo típico de otras poblaciones de Honduras. Conclusiones: muchas de las comunidades estudiadas presentan una elevada consanguinidad debido al aislamiento, la segregación étnica y/o costumbres endogámicas.

  12. Model parameter estimations from residual gravity anomalies due to simple-shaped sources using Differential Evolution Algorithm

    NASA Astrophysics Data System (ADS)

    Ekinci, Yunus Levent; Balkaya, Çağlayan; Göktürkler, Gökhan; Turan, Seçil

    2016-06-01

    An efficient approach to estimate model parameters from residual gravity data based on differential evolution (DE), a stochastic vector-based metaheuristic algorithm, has been presented. We have showed the applicability and effectiveness of this algorithm on both synthetic and field anomalies. According to our knowledge, this is a first attempt of applying DE for the parameter estimations of residual gravity anomalies due to isolated causative sources embedded in the subsurface. The model parameters dealt with here are the amplitude coefficient (A), the depth and exact origin of causative source (zo and xo, respectively) and the shape factors (q and ƞ). The error energy maps generated for some parameter pairs have successfully revealed the nature of the parameter estimation problem under consideration. Noise-free and noisy synthetic single gravity anomalies have been evaluated with success via DE/best/1/bin, which is a widely used strategy in DE. Additionally some complicated gravity anomalies caused by multiple source bodies have been considered, and the results obtained have showed the efficiency of the algorithm. Then using the strategy applied in synthetic examples some field anomalies observed for various mineral explorations such as a chromite deposit (Camaguey district, Cuba), a manganese deposit (Nagpur, India) and a base metal sulphide deposit (Quebec, Canada) have been considered to estimate the model parameters of the ore bodies. Applications have exhibited that the obtained results such as the depths and shapes of the ore bodies are quite consistent with those published in the literature. Uncertainty in the solutions obtained from DE algorithm has been also investigated by Metropolis-Hastings (M-H) sampling algorithm based on simulated annealing without cooling schedule. Based on the resulting histogram reconstructions of both synthetic and field data examples the algorithm has provided reliable parameter estimations being within the sampling limits of

    The μ ^- + ^3H → ν _μ + n + n + n capture reaction is studied under full inclusion of final-state interactions with the AV18 nucleon-nucleon potential and the Urbana IX three-nucleon force. We employ the single nucleon weak current operator comprising the dominant relativistic corrections to obtain first estimates of the total capture rates based on realistic forces. Our results are compared with older theoretical predictions.

    We report on the most recent applications of the Auxiliary Field Diffusion Monte Carlo (AFDMC) method. The equation of state (EOS) for pure neutron matter in both normal and BCS phase and the superfluid gap in the low-density regime are computed, using a realistic Hamiltonian containing the Argonne AV8' plus Urbana IX three-nucleon interaction. Preliminary results for the EOS of isospin-asymmetric nuclear matter are also presented.

    1990-01-01

    A novel algorithm, called the lambda test, is presented for an efficient and accurate data dependence analysis of multidimensional array references. It extends the numerical methods to allow all dimensions of array references to be tested simultaneously. Hence, it combines the efficiency and the accuracy of the both approaches. This algorithm has been implemented in PARAFRASE, a FORTRAN program parallelization restructurer developed at the University of Illinois at Urbana-Champaign. Some experimental results are presented to show its effectiveness.

    221 upperclassmen at the University of Illinois at Champaign-Urbana were polled about their attitudes on selected current sexual topics. Total group responses indicated very liberal views toward birth control, sex education and sexual standards. Although still liberal, the most conservative responses were toward college marriages and homosexuality. Females were slightly more liberal about sex education, divorce, and homosexuality; males were more liberal about sexual standards. Attitudes were quite similar between males and females. Neither group supported the most liberal statements in the poll. Results of the study indicate a slow change in behavior, attitudes, and knowledge about sex, not a "sexual revolution."

    Valentine, R. C. (University of Illinois, Urbana) and R. S. Wolfe. Role of ferredoxin in the metabolism of molecular hydrogen. J. Bacteriol. 85:1114-1120. 1963.-The metabolism of molecular hydrogen by Clostridium pasteurianum, Micrococcus lactilyticus (Veillonella alcalescens), and several other anaerobic bacteria was studied. Oxidation of hydrogen, using several electron-accepting substrates including triphosphopyridine nucleotide, uric acid, xanthine, nitrite, and hydroxylamine, required ferredoxin in conjunction with hydrogenase. Evolution of hydrogen from pyruvate, alpha-ketoglutarate, hypoxanthine, and dithionite was mediated by ferredoxin. On the basis of these findings, a unitary hypothesis for biological hydrogen evolution is proposed in which ferredoxin plays a key role.

    Haider, W.; Sharma, Manjari; Gambhir, Y. K.; Kailas, S.

    2010-03-15

    We present a Brueckner theory analysis of proton-scattering data from Sn isotopes at 295 MeV. A soft-core Urbana v{sub 14} internucleon potential has been used to calculate reaction matrices that are folded with point-nucleon (both proton and neutron) densities obtained in the relativistic mean field (RMF) framework to calculate the optical potential. We get reasonably satisfactory agreement with the differential cross-section and analyzing-power data using only three scaling parameters for all isotopes. It is observed that the calculated neutron skin increases smoothly as the neutron number increases, in conformity with earlier findings.

    Two long-standing issues in photonuclear physics, the giant M1 resonance in Pb and deuteron photodisintegration, have been studied recently with polarized photons at Urbana and Frascati, respectively. The implications that this work has for settling these key issues will be discussed. In addition, the advantages of the internal polarized target method for electron scattering studies will be discussed and the technology of internal polarized target development will be reviewed. The first results from a spin-exchange, optically-pumped polarized H and D source will be presented.

    2006-03-01

    The He4 total photoabsorption cross section is calculated with the realistic nucleon-nucleon potential Argonne V18 and the three-nucleon force (3NF) Urbana IX. Final state interaction is included rigorously via the Lorentz integral transform method. A rather pronounced giant resonance with peak cross sections of 3.0 (3.2) mb is obtained with (without) the 3NF. Above 50 MeV strong 3NF effects, up to 35%, are present. Good agreement with experiment is found close to threshold. A comparison in the giant resonance region is inconclusive, since data do not show a unique picture.

    1998-06-01

    This letter presents an experimental verification of the super-resolution phenomenon in a nonlinear inverse scattering algorithm, namely the distorted Born iterative method, by using an experimental setup based on a recently developed time-domain ultra-wide-band radar imaging system at the University of Illinois at Urbana-Champaign. The experimental result also demonstrates that the distorted Born iterative method can recover information on the backside of a penetrable scatterer even though scattering data are collected only from limited viewing angles on the front side of the scatterer.

    2015-12-01

    Using the hyperspherical adiabatic method with the realistic nuclear potentials Argonne V14, Argonne V18, and Argonne V18 with the Urbana IX three-body potential, we calculate the adiabatic potentials and the triton bound state energies. We find that a discrete variable representation with the slow variable discretization method along the hyperradial degree of freedom results in energies consistent with the literature. However, using a Laguerre basis results in missing energy, even when extrapolated to an infinite number of basis functions and channels. We do not include the isospin T = 3/2 contribution in our analysis.

    A flexible very high frequency (VHF) stratosphere-troposphere (ST) radar configured for meteorological research is to be constructed near Urbana, Illinois. Measurement of small vertical velocities associated with synoptic-scale meteorology can be performed. A large Doppler microwave radar (CHILL) is located a few km from the site of the proposed ST radar. Since the microwave radar can measure the location and velocity of hydrometeors and the VHF ST radar can measure clear (or cloudy) air velocities, simultaneous observations by these two radars of stratiform or convective weather systems would provide valuable meteorological information.

    Introducción: La neumonía adquirida en la comunidad (NAC) es un problema serio de salud a nivel mundial. El objetivo es evaluar la eficacia y la seguridad del tratamiento ambulatorio de la neumonía adquirida en la comunidad. Métodos: se realizó una revisión sistemática y un metaaanálisis de ensayos clínicos aleatorizados que evaluaran la eficacia y la seguridad del tratamiento ambulatorio (TA) comparado con el hospitalario (TH) de la neumonía adquirida en la comunidad, en pacientes sin comorbilidad agregada. Se calcularon riesgos relativos (RR) e intervalos de confianza al 95 % (IC 95 %). Resultados: Se identificaron 4088 títulos, solo dos artículos fueron incluidos en el metaanálisis, uno realizado en adultos y el otro en población pediátrica. Se incluyeron 2324 pacientes. El TA presentó menos fallas que el TH ( TA 12.6 frente a TH 15.21 %, RR 0.84 [IC 95% 0.68-1.02]). En relación con la seguridad se presentaron dos defunciones (0.17 %) en el TA y cuatro en el TH (0.34 %) (RR 0.56 [IC 95 % 0.12-2.61]). Finalmente, tampoco encontramos diferencia en la readmisión hospitalaria entre los grupos (RR 0.82 [IC 95 % 0.52-1.30]). Conclusión: la evidencia muestra que no existen diferencias estadísticamente significativas entre el tratamiento ambulatorio y el tratamiento hospitalario de la neumonía adquirida en la comunidad.

    There are recognized needs for cross-training health professionals in human, animal, and ecosystem health and for public health policy to be informed by experts from medical, science, and social science disciplines. Faculty members of the Community Health and Preventive Medicine Section at the University of Illinois at Urbana-Champaign, College of Veterinary Medicine, and the Institute of Government and Public Affairs, University of Illinois at Urbana-Champaign, have offered a public-policy course designed to meet those needs. The course was designed as a practicum to teach students the policy-making process through the development of policy proposals and to instruct students on how to effectively present accurate scientific, demographic, and statistical information to policy makers and to the public. All students substantially met the learning objectives of the course. This course represents another model that can be implemented to help students learn about complex, multifactorial issues that affect the health of humans, animals, and ecosystems, while promoting participation in public health policy development.

    1981-01-01

    The development and first observations of the partial-reflection drifts experiment at Urbana, Illinois (40 N) are described. The winds data from the drifts experiment are compared with electron concentration data obtained by the differential-absorption technique to study the possible meteorological causes of the winter anomaly in the mesosphere at midlatitudes. winds data obtained by the meteor-radar experiment at Urbana are also compared with electron concentration data measured at Urban. A significant correlation is shown is both cases between southward winds and increasing electron concentration measured at the same location during winter. The possibility of stratospheric/mesospheric coupling is investigated by comparing satellite-measured 0.4 mbar geopotential data with mesospheric electron concentration data. No significant coupling was observed. The winds measured at Saskatoon, Saskatchewan (52 N) are compared with the electron concentrations measured at Urban, yielding constant fixed relationship, but significant correlations for short segments of the winter. A significant coherence is observed at discrete frequencies during segments of the winter.

    Colin Allen Wraight (1945-2014) was a well-known biophysicist and biochemist of our times-formerly Professor of Biochemistry, Biophysics and Plant Biology, and Head of the Department of Biochemistry, University of Illinois at Urbana-Champaign, Urbana, IL, USA. (See a detailed Tribute to him by Govindjee et al., Photosynth Res, 2015.) During the latter part of his life, Colin had (1) given an excellent lecture in 2008 on the overall topic of the molecular mechanisms in biological energy conversion, focusing on how an ubiquinone is reduced to ubiquinol at the so-called "two electron gate", and (2) presented a review poster on the design features of long distance proton transport in biological systems, with focus on photosynthetic bacteria (a pdf file of the original is available from one of us, Govindjee). We present here for historical purpose, a complete transcript of his 2008 lecture and his 2013 poster, which have been annotated and expanded by the authors of this paper. The major theme is: electron and proton transfer in biological systems, with emphasis on bacterial reaction centers. The figures, some of which were prepared by us, are presented in sequence for both the lecture and the poster. A common bibliography is provided at the end of the paper, which is divided into two parts: (I) The Lecture; and (II) The Poster.

    Mumps is an acute viral disease characterized by fever and swelling of the parotid or other salivary glands. On May 1, 2015, the Illinois Department of Public Health (IDPH) confirmed a mumps outbreak at the University of Illinois at Urbana-Champaign. IDPH and the Champaign-Urbana Public Health District (C-UPHD) conducted an investigation and identified 317 cases of mumps during April 2015-May 2016. Because of sustained transmission in a population with high 2-dose coverage with measles-mumps-rubella (MMR) vaccine, a third MMR dose was recommended by IDPH, C-UPHD, and the university's McKinley Health Center. No formal recommendation for or against the use of a third MMR dose has been issued by the Advisory Committee on Immunization Practices (ACIP) (1). However, CDC has provided guidelines for use of a third dose as a control measure during mumps outbreaks in settings in which persons are in close contact with one another, where transmission is sustained despite high 2-dose MMR coverage, and when traditional control measures fail to slow transmission (2).

  16. Lidar observations of seasonal variation of diurnal mean temperature in the mesopause region over Fort Collins, Colorado (41°N, 105°W)

    Two campaigns from February 1997 to January 1999 have resulted in 18 sets of continuous temperature measurements in the mesopause region over Fort Collins, Colorado (41°N, 105°W), each covering a complete diurnal cycle, reasonably well distributed throughout the year. It is shown that the winter-summer transitions, based on diurnal means, are abrupt and clear, further strengthening the concept of two-level mesopause, and demonstrate the robustness of this picture. Similar to data taken at Urbana, Illinois, our data at Fort Collins also demonstrate the need to observe over a complete diurnal cycle to deduce the uncontaminated mean temperature structure and seasonal variations in the mesopause region. The difference between annual diurnal, nighttime, and daytime means may be ascribed to a temperature wave propagating with a downward phase speed of ˜0.8 km/h. Our data show that the nighttime annual mean is colder than the diurnal annual mean by no more than 2 K below 88 km and warmer by no more than 3 K above 88 km where the three means are nearly the same. As in the Urbana data, we also observed the altitude of a secondary temperature minimum in the summer to be ˜96 km, which without strong dynamical cooling in the summer would have been the summer mesopause altitude.

    2012-12-01

    In June and July of 2012, three new imaging Fabry-Perot interferometers (FPI) were installed at the Urbana Atmospheric Observatory in Urbana, IL (University of Illinois), Peach Mountain Observatory in Pinkney, MI (University of Michigan), and Richmond, KY (Eastern Kentucky University). Together with the existing FPI operating at the Pisgah Astronomical Research Institute in Rosman, NC (Clemson University), these FPIs form the initial deployment of the North American Thermosphere-Ionosphere Observing Network (NATION). NATION represents a new midlatitude chain of instruments capable of providing measurements of the thermospheric neutral winds and temperatures through observations of the redline emission at 630.0 nm. We present results from the first five months of operations of these instruments. The capabilities of the network are also demonstrated, first with each instrument operating as a stand alone observatory and then with each instrument operating in concert with one another to form a distributed sensing system capable of providing temperature and horizontal vector wind measurements over the midwestern United States.

  18. The diurnal and semidiurnal oscillations in meteor winds over Atlanta

    NASA Astrophysics Data System (ADS)

    Ahmed, M. I.; Roper, R. G.

    The wind data collected over Atlanta during the period August 1974-February 1978 using the Georgia Tech Radio Meteor Wind Facility, is analyzed to yield an average picture of the seasonal behavior of its diurnal tides. Both the zonal and meridional components are studied. The vertical structures of these oscillations over Atlanta are compared with similar studies over Garchy, Urbana and Adelaide. For the semidiurnal tide: the vertical structure during winter appears to have a strong latitude dependence, with vertical wavelength increasing with decreasing latitude; in spring, the (2, 4) and (2, 6) modes appear to dominate at all stations; in summer, the behavior is the same at all four locations, characterized by the apparent domination of the (2,2) mode; in autumn, both the Garchy and Atlanta results indicate the presence of a (2,2) mode, while the (2,4) mode appears to dominate over Urbana. The behavior of the diurnal tide is less well defined: during winter, as latitude decreases from Garchy to Atlanta, evanescent and higher order propagating modes seem to dominate; both spring and summer are characterized by a gradual decrease in observed vertical wavelengths as latitude decreases; in northern hemisphere autumn, the fundamental (1, 1) mode appears to dominate, but at Adelaide in southern hemisphere autumn, predominatly evanescent modes are observed.

  20. The Early Developments of the Theory of the Mössbauer Effect

    NASA Astrophysics Data System (ADS)

    Lipkin, Harry J.

    I was at the University of Illinois at Urbana in the academic year 1958-1959 when I first heard about the Mössbauer effect. My contacts with Bardeen and his theory group taught me everything I needed to know about solid state physics to understand the Mössbauer effect. I also learned at Urbana from Fred Seitz that my old friend Kundan Singwi had done pioneering work in neutron scattering which was very relevant to the Mössbauer effect. I had met Kundan and his wife Helga in 1953 when we were both postdocs learning about nuclear energy at Saclay, lived in the same pension operated by the French Atomic Energy Commission, and had dinner together every evening. It was a pleasure to renew our contacts after their arrival at Argonne in 1959 when we were both involved in the Mössbauer effect, and during an extended period while he was at Argonne and we visited every summer. I shall miss both John and Kundan.

  1. Simulation studies of the membrane exchange assembly of an all-liquid, proton exchange membrane fuel cell

    NASA Astrophysics Data System (ADS)

    Byrd, Ethan D.; Miley, George H.

    A model has been designed and constructed for the all-liquid, sodium borohydride/hydrogen peroxide fuel cell under development at the University of Illinois at Urbana-Champaign. The electrochemical behavior, momentum balance, and mass balance effects within the fuel cell are modeled using the Butler-Volmer equations, Darcy's law, and Fick's law, respectively, within a finite element modeling platform. The simulations performed with the model indicate that an optimal physical design of the fuel cell's flow channel land area or current collector exists when considering the pressure differential between channels, and the diffusion layer permeability and conductivity. If properties of the diffusion layer are known, the model is an effective method of improving the fuel cell design in order to achieve higher power density.

    Drake, John W. (University of Illinois, Urbana). Ultraviolet mutagenesis in bacteriophage T4. I. Irradiation of extracellular phage particles. J. Bacteriol. 91:1775–1780. 1966.—Ultraviolet (UV) irradiation of extracellular T4 phage particles induces about 2 × 10−4r mutations per lethal hit. The mutants largely escape detection unless the irradiated phages are plated with very soft overlay agar. Multiplicity reactivation is not a prerequisite for mutagenesis. A much higher frequency of base pair substitution-type mutants is induced than is found in the spontaneous background, but sign mutants are also induced. Nearly half of the mutants map into previously identified UV hot spots. The rII mutants induced extracellularly are very similar to those induced intracellularly. The mutants also appear to result from direct radiation effects upon the bacteriophage deoxyribonucleic acid. PMID:5937237

    Meteoritic ablation in the upper atmosphere is the commonly accepted source of the mesospheric metals between 80 and 105 km. The vertical and temporal behavior of some of these metals can be probed with high accuracy and resolution using resonance fluorescence lidar techniques. Of considerable interest in recent years has been the sporadic and rapid formation of thin, dense enhancements in these metallic layers. Since late Mar. 1991, the UIUC CEDAR lidar system, located at the Urbana Atmospheric Observatory, has been routinely operating at the Fe resonance line of 372 nm in order to probe the mesospheric Fe layer. In Nov. 1991, the capability to investigate mesospheric Ca(+) at the resonance line of 393.4 nm was added. The lidar's eximer-pumped dye laser uses Exciton QUI laser dye dissolved in p-dioxane, which can lase at both the Fe and Ca(+) frequencies. Various aspects of this investigation are discussed.

    We describe a new suite of instruments planned for deployment to Cape Verde as part of the International Heliospherical Year. The Remote Equatorial Nighttime Observatory of Ionospheric Regions (RENOIR) project consists of a bistatic Fabry-Perot interferometer system, an all-sky imaging system, a dual-frequency Global Positioning System (GPS) receiver, and an array of single-frequency GPS scintillation monitors. This instrumentation will allow for studying the low-latitude thermosphere/ionosphere (TI) system in great detail. Investigations to be conducted using this instrumentation while in Cape Verde include studying equatorial irregularity processes, the effects of neutral winds and gravity waves on irregularity development, the midnight temperature maximum, and ion-neutral coupling in the nighttime TI system. Initial observations from the RENOIR instrumentation during pre-deployment testing at the Urbana Atmospheric Observatory are presented, as is the deployment scenario for the project in Cape Verde.

    Three well-known photonuclear sum rules (SR), i.e., the Thomas-Reiche-Kuhn, the bremsstrahlungs and the polarizability SR are calculated for He4 with the realistic nucleon-nucleon potential Argonne V18 and the three-nucleon force Urbana IX. The relation between these sum rules and the corresponding energy weighted integrals of the cross section is discussed. Two additional equivalences for the bremsstrahlungs SR are given, which connect it to the proton-neutron and neutron-neutron distances. Using them, together with our result for the bremsstrahlungs SR, we find a deviation from the tetrahedral symmetry of the spatial configuration of He4. The possibility to access this deviation experimentally is discussed.

  6. 100 years of Pb deposition and transport in soils in Champaign, Illinois, U.S.A

    2003-01-01

    In Illinois, atmospheric deposition is one major source of heavy metal inputs to agricultural land. The atmospheric Pb deposition and transport record in agricultural soils in Champaign, Illinois, was established by studying surface and subsurface soil samples collected during the past 100 years from the Morrow Plots on the campus of the University of Illinois at Urbana-Champaign. The Pb content in the soil samples was measured and the Ph deposition fluxes were calculated. The Pb content in surface soils increased sharply in the first half of the 20th century, and stayed invariant since. The maximum Pb flux from the atmosphere was estimated to be 27 (??14) ??g cm-2 yr-1 around 1940. The major pollution source for this increase probably was residential coal burning. It was estimated that in 50 yr, more than 50% of the Pb input had been lost from the surface soils.

    A real time, distance lab module is being developed and implemented in the Dept. of Nuclear, Plasma and Radiological Engineering at the Univ. of Illinois at Urbana-Champaign. This internet based system allows remote personnel to watch the experiments, acquire data, and interact with on-site personnel. The e-lab broadcasts not only the live scenes of laboratory and experiments, but also the real time data and plots being measured and displayed in graphical and other formats. Moreover, use of LabVIEW's remote front panel feature allows communications between the local lab and remote client so that, if permitted, remote client can control part or all of the experiment in real-time.

    The participation of the University of Illinois at Urbana-Champaign in the NASA/USRA Universities Advanced Engineering Design Program (Space) is reviewed for the 1987 to 88 academic year. The University's design project was the Manned Marsplane and Delivery System. In the spring of 1988 semester, 107 students were enrolled in the Aeronautical and Astronautical Engineering Departments' undergraduate Aerospace Vehicle Design course. These students were divided into an aircraft section (responsible for the Marsplane design), and a spacecraft section (responsible for the Delivery System Design). The design results are presented in Final Design Reports, copies of which are attached. In addition, five students presented a summary of the design results at the Program's Summer Conference.

    2000-04-01

    We continue the investigations of ground state properties of closed-shell nuclei using the Argonne v18 realistic NN potential, together with the Urbana IX three-nucleon interaction. The ground state wave function is used to calculate the charge form factor and charge density. Starting with the ground state wave function of the closed-shell nucleus, we use the equation of motion technique to calculate the ground state and excited states of a neighboring nucleus. We then generate the corresponding magnetic form factor. We correct for distortions due to the interaction between the electron probe and the nuclear Coulomb field using the DWBA picture. We compare our results with the available experimental data. Even though our presentation will focus mainly on the ^16O and ^15N nuclei, results for other nuclei in the p and s-d shell will also be presented.

    1991-09-01

    Three-dimensional gaging involves the measurement and mapping of 3-D surfaces. Gaging accuracy depends on measurement accuracy in the images, image scale, and stereo geometry. Multiple cameras are often needed to provide adequate stereoscopic coverage of the object. This paper reports on an automatic 3-D gaging system that is being developed at the University of Illinois at Urbana-Champaign. A portable 3-D target field, consisting of 198 targets each identified with a bar code, is used to determine the interior and exterior orientation parameters of each camera. Image-processing algorithms have been developed to identify conjugate image points in stereo pair of images, and the object-space coordinates of these points are computed by stereo intersection. Software has also been developed for analysis and data editing.

  12. Observations of the breakdown of an atmospheric gravity wave near the cold summer mesopause at 54N

    2000-03-01

    Recently, it was shown from a single set of airglow/lidar observations in Urbana, Illinois (40N) that some small-scale wave-like structure seen in OH airglow images can be associated with the breakdown, via a convective instability, of an atmospheric gravity wave. A second set of simultaneous airglow/lidar observations, showing wave breakdown, has been obtained over Kühlungsborn, Germany (54N) during a period when noctilucent clouds (NLCs) were also observed. This showed that the wave breakdown process can occur under the same cold, low altitude summer mesopause conditions that support the occurrence of NLCs. This new set of data shows that the first observations were not a unique event, and give credence to the suggestion that some of the small scale structure seen in NLC displays may be due to wave breakdown.

    We present the concept, design, and first results of a spectrally very agile Raman spectrometer that has a fully achromatic and parabolic focussing on the sample and an achromatic coupling into a spectrometer that operates in a wavelength range between 185 and 900 nm. Due to the diffraction limited imaging it features very high spectral and spatial resolution as well as excellent efficiency. A special spatial filter stage between the two subtractively coupled premonochromators allows very high straylight rejection even in the deep ultraviolett spectral range. This filter stage is also common to all systems previously developed in the 'ultimative triple' series by Miles Klein (Urbana-Champaign) and is shown here to be crucial for measurements in this difficult spectral range. First results of resonance Raman measurements on Silicon, LaMnO3 and the Keratin matrix are shown and compared with theoretical expectations.

    2009-03-01

    We have used electron beam evaporation of solid carbon (C) to deposit graphene on MgO <111> at 850C. The growth appears epitaxial as observed by in-situ RHEED which also reveals that the hot scattering surface transitions from an insulator to a conductor after deposition of 1 monolayer of C. Growth at higher temperatures gives better crystallinity. We further characterize the film by ex-situ Raman spectroscopy, AFM and transport. Raman reveals all the characteristic G, D and 2D peaks of graphene and the 2D peak can be fit to a single lorentzian typical for graphene. AFM pictures show that the surface consists of flat connected domains, which are uniform across the substrate. Electrical transport shows insulating behavior with resistance (R) varying as 1/T^2. This work was supported by the DOE BES at the F. Seitz Materials Research Laboratory at the University of Illinois, Urbana.

  15. Statistical multiscale blob features for classifying and retrieving image texture from large-scale databases

    2010-10-01

    The extraction of texture features from images faces two new challenges: large-scale databases with diversified textures, and varying imaging conditions. We propose a novel method termed multiscale blob features (MBF) to overcome these two difficulties. MBF analyzes textures in both resolution scale and gray level. Proposed statistical descriptors effectively extract structural information from the decomposed binary images. Experimental results show that MBF outperforms other methods on combined large-scale databases (VisTex+Brodatz+CUReT+OuTex). Moreover, experimental results on the University of Illinois at Urbana-Champaign database and the entire Brodatz's atlas show that MBF is invariant to gray-level scaling and image rotation, and is robust across a substantial range of spatial scaling.

    The Ribosomal Database Project (RDP) grew out of Carl Woese’s vision of how rRNA comparative methods could transform biology. First at the University of Illinois Urbana-Champaign, and later at Michigan State University’s Center for Microbial Ecology, the project has grown from a few hundred to several million rRNA gene sequences. In the years since Woese started the RDP, publications describing the database and related tools have been cited over 11 000 times in journals spanning a wide range of disciplines, while the RDP website is accessed by 10 000 researchers in over 20 000 analysis sessions each month. This article describes the history of RDP’s development over the last two decades. PMID:24607969

    We report recent quantum Monte Carlo (variational and Green's function) calculations of elastic nucleon-nucleus scattering. We are adding the cases of proton-^4He, neutron-^3H and proton-^3He scattering to a previous GFMC study of neutron-^4He scattering [1]. To do this requires generalizing our methods to include long-range Coulomb forces and to treat coupled channels. The two four-body cases can be compared to other accurate four-body calculational methods such as the AGS equations and hyperspherical harmonic expansions. We will present results for the Argonne v18 interaction alone and with Urbana and Illinois three-nucleon potentials. [4pt] [1] K.M. Nollett, S. C. Pieper, R.B. Wiringa, J. Carlson, and G.M.

    Microarray-based serogenotyping, antimicrobial susceptibility tests and the detection of relevant resistance genes were performed on isolates of Salmonella spp. from retail meat samples obtained in Lagos, Nigeria. Out of 151 meat samples, 33 Salmonella isolates were obtained. Nine different Salmonella serovars (S. Amoutive, S. Bargny, S. Drac, S. Ealing, S. Urbana, S. Hadar, S. Nyborg, S. Anatum and S. Havana) were identified by microarray-based serogenotyping and confirmed afterwards using classical serotyping. Antibiotic susceptibility tests with 17 antibiotics showed that almost all isolates were fully susceptible to this panel. The results of this study indicated a high prevalence of Salmonella in retail meat, the presence of some previously rather rarely described Serovars in retail meat samples from Lagos, and a need to monitor for Salmonella and their antibiotic resistance determinants. The microarray-based system used herein proved to be perfectly suited as epidemiological tool to replace classical serotyping.

    2007-03-15

    A comparative study of the microscopic optical potentials viz., semimicroscopic with extended Jeukenne-Lejeune-Mahaux interaction and microscopic Brueckner theory using Hamada-Johnston as well as Urbana V14 soft-core internucleon interactions, has been carried out. These microscopic optical potentials are compared with that of Dirac phenomenology (DP) for the polarized proton-{sup 40}Ca elastic scattering at 35 MeV and 200 MeV. These potentials have different shapes for 200 MeV below 4 fm. In particular, for the real part of the central potential, only the Dirac phenomenology and the microscopic optical potential calculated with the Hamada-Johnston interaction exhibit the well known wine-bottle-bottom shape. It is found that the calculated observables (cross section, analyzing power and spin rotation function) using these potentials having different shapes, compare well with the experiment.

    1998-01-01

    In support of the NASA Lewis Modern Airfoils Ice Accretion Test Program, the University of Illinois at Urbana-Champaign provided expertise in airfoil design and aerodynamic analysis to determine the aerodynamic effect of ice accretion on modern airfoil sections. The effort has concentrated on establishing a design/testing methodology for "hybrid airfoils" or "sub-scale airfoils," that is, airfoils having a full-scale leading edge together with a specially designed and foreshortened aft section. The basic approach of using a full-scale leading edge with a foreshortened aft section was considered to a limited extent over 40 years ago. However, it was believed that the range of application of the method had not been fully exploited. Thus a systematic study was being undertaken to investigate and explore the range of application of the method so as to determine its overall potential.

    The zebrafish larva is a thoroughly studied and an extensively used model for behavioral and biomedical research. The Zebrafish Laboratory at the University of Illinois at Urbana-Champaign has applied a mathematical method to describe quantitatively the larva's swimming behavior. With this method, the 98% of the larva's free-swimming behavior is described by its simplifiedeigen-fish model, which is a linear combination of its three characteristic components, or three eigen-modes. This presentation focuses on the quantification of a different swimming behavior called escape response in wildtype (WT) zebrafish larvae. Although more data is required before assuming certainty in our results, the escape response of the WT was also described up to 98% by three eigen-modes. This REU program is supported by NSF Grant PHY-1062690.

    The neutron spin rotation induced by parity-violating (PV) components in the nucleon-nucleon potential is studied in $\\vec{n}$-$d$ scattering at zero energy. Results are obtained corresponding to the Argonne $v_{18}$ two-nucleon and Urbana-IX three-nucleon strong-interaction potentials in combination with either the DDH or pionless EFT model for the weak-interaction potential. We find that this observable is dominated by the contribution of the long-range part of the PV potential associated with pion exchange. Thus its measurement could provide a further constraint, complementary to that coming from measurements of the photon asymmetry in $\\vec{n}$-$p$ radiative capture, on the strength of this component of the hadronic weak interaction.

    Plasma disruptions pose a major threat to the operation of tokamaks which confine a large amount of stored energy. In order to effectively mitigate this damage it is necessary to predict an oncoming disruption with sufficient warning time to take mitigative action. Machine learning approaches to this problem have shown promise but require further developments to address (1) the need for machine-portable predictors and (2) the availability of multi-dimensional signal inputs. Here we demonstrate progress in these two areas by applying the Disruption Predictor Feature Developer to data from JET and NSTX, and discuss topics of focus for ongoing work in support of ITER. The author is also supported under the Fulbright U.S. Student Program as a graduate student in the department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at Urbana-Champaign.

Bacteriol. 87:241–246. 1964.—Extracts of Streptococcus allantoicus were found to degrade glyoxylate, yielding tartronic semialdehyde and CO2. Tartronic semialdehyde was prepared chemically, and its properties were compared with the enzymatic product: reduction by sodium borohydride yielded glycerate; heating at 100 C yielded glycolaldehyde and CO2; autoxidation yielded mesoxalic semialdehyde; periodate oxidation yielded glyoxylate and a compound presumed to be formate. Tartronic semialdehyde reductase was present in extracts of S. allantoicus and in a species of Pseudomonas grown on allantoin. A scheme for the synthesis of acetate from glyoxylate by S. allantoicus is discussed. PMID:14151040

    Recent advances in the study of electrodisintegration of 3He are presented and discussed. The pair-correlated hyperspherical harmonics method is used to calculate the initial and final state wave functions, with a realistic Hamiltonian consisting of the Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. The model for the nuclear current and charge operators retains one- and many-body contributions. Particular attention is made in the construction of the two-body current operators arising from the momentum-dependent part of the two-nucleon interaction. Three-body current operators are also included so that the full current operator is strictly conserved. The present model for the nuclear current operator is tested comparing theoretical predictions and experimental data of pd radiative capture cross section and spin observables.

    Argonne National Laboratory leads the Joint Center for Energy Storage Research (JCESR), a major collaborative research partnership with the goal of developing next-generation energy storage technologies. JCESR supplements its traditional project management approach with scientific “Sprints.” The Sprint described in this video involved a multidisciplinary team from Argonne, the University of Illinois at Urbana-Champaign, Massachusetts Institute of Technology, and the University of Michigan. As they studied how polymers in solution can react electrochemically to store energy, the team solved a crucial battery problem: “crossover,” which is caused by molecules mixing together when they should not, resulting in reduced performance. Many possible materials were tested, and a set of candidate polymers were chosen that are stable, cheap to make, and suitable for conditions required in batteries. The collaboration allowed timely development that would have taken much longer had the groups been working independently.

    Examination of research productivity has a long history in psychology. Journals across psychology have periodically published research-productivity studies. An analysis of institutional research productivity was conducted for 17 journals published by the American Psychological Association for the years 1986-2008. This analysis implemented two methodologies: one a replication and extension of G. S. Howard, D. A. Cole, and S. E. Maxwell's (1987) method, the other a new method designed to give credit to psychology departments rather than only overall institutions. A system of proportional credit assured all articles with multiple institutions received credit. Results show that for the 23-year period, the University of Illinois at Urbana-Champaign was ranked 1st, followed by the University of California, Los Angeles, and the University of Michigan, Ann Arbor. Overall, results showed both consistency and change across all journals examined. The authors explore the implications of these findings in the context of the current academic environment.

    2002-06-01

    In the present work we apply the lowest order Brueckner theory of infinite nuclear matter to obtain nucleon-nucleus optical potential for p-40Ca elastic scattering at 200 MeV using Urbana V14 soft core internucleon potential. We have investigated the effect of target density on the calculated nucleon-nucleus optical potential. We find that the calculated optical potentials depend quite sensitively on the density distribution of the target nucleus. The important feature is that the real part of calculated central optical potential for all densities shows a wine-bottle-bottom type behaviour at this energy. We also discuss the effect of our new radial dependent effective mass correction. Finally, we compare the prediction of our calculated nucleon optical potential using V14 with the prediction using older hard core Hamada-Johnston internucleon potential for p-40Ca elastic scattering at 200 MeV.

    An Inertial-Electrostatic Confinement (IEC) device was assembled at the Marshall Space Flight Center (MSFC) Propulsion Research Center (PRC) to study the possibility of using EEC technology for deep space propulsion and power. Inertial-Electrostatic Confinement is capable of containing a nuclear fusion plasma in a series of virtual potential wells. These wells would substantially increase plasma confinement, possibly leading towards a high-gain, breakthrough fusion device. A one-foot in diameter IEC vessel was borrowed from the Fusion Studies Laboratory at the University of Illinois@Urbana-Champaign for the summer. This device was used in initial parameterization studies in order to design a larger, actively cooled device for permanent use at the PRC.

    Recently it was proved that the neutron matter interacting through Argonne V18 pair-potential plus modern variants of Urbana or Illinois three-body forces is unstable. For the energy of N neutrons E(N), which interact through these forces one has E(N) = −cN³⁺+O(N{sup 8/3}), where c > 0 is a constant. This means that: (i) the energy per particle and neutron density diverge rapidly for large neutron numbers; (ii) bound states of N neutrons exist for N large enough. The neutron matter collapse is possible due to the form of the repulsive core in three-body forces, which vanishes when three nucleons occupy the same site in space. The obtained results partly change the paradigm, in which the stability of neutron stars is attained through the Pauli principle; the strong repulsive core in the nucleon interactions is by no means less important.

    Introducción: Guatemala ha estado experimentando una transición en sus estilos de vida. Mientras que la desnutrición crónica sigue siendo prevalente, se ha experimentado un aumento sustancial de los casos de obesidad. Objetivo: proporcionar información actualizada sobre las nuevas tendencias en cuanto al estado nutricional en Guatemala. Métodos: se diseñó un estudio transversal con una muestra de 392 niños y adolescentes (5-18 años) seleccionados de manera aleatoria. El muestreo fue estratificado según su ubicación geográfica (rural y urbana), sexo y edad. Resultados: alrededor del 62% de la muestra urbana presentó problemas de sobrepeso y un 13,8 de obesidad. Entre los participantes urbanos, la prevalencia de sobrepeso/obesidad fue mayor en el grupo de 11-14 años. El grupo urbano presentó una mayor prevalencia de sobrepeso/obesidad que el grupo rural para todos los grupos de edad (excepto en el grupo de 15-18 años que presentó unos índices de obesidad ligeramente más elevados en el grupo rural). Se observó una mayor prevalencia de retraso en el crecimiento en el grupo rural, excepto para el grupo de edad de 15-18 años. La prevalencia de bajo peso fue significativamente mayor en el grupo rural (25% vs. 1,2%) así como la prevalencia del delgadez, excepto para el grupo de edad de 5-10 años. Conclusión: la alta prevalencia de bajo peso y la de sobrepeso/obesidad coexisten en los niños y adolescentes en Guatemala.

La estructura del modelo muestra muy buena estabilidad en la estructura factorial y las dimensiones de la escala fueron equivalentes en las muestras analizadas. Conclusión: La modelización mediante ecuaciones estructurales muestra un modelo parsimonioso que, puede ser utilizado para explicar las variaciones en el consumo de fruta en niños escolares mexicanos de 10 a 12 años. La estructura del modelo fue estrictamente invariante y muestra evidencias de validación cruzada. Finalmente, se discuten las modificaciones requeridas para obtener un mejor ajuste de los datos en contextos escolares y las directrices a seguir en futras investigaciones.

  20. Assessing composition and structure of soft biphasic media from Kelvin–Voigt fractional derivative model parameters

    Kelvin–Voigt fractional derivative (KVFD) model parameters have been used to describe viscoelastic properties of soft tissues. However, translating model parameters into a concise set of intrinsic mechanical properties related to tissue composition and structure remains challenging. This paper begins by exploring these relationships using a biphasic emulsion materials with known composition. Mechanical properties are measured by analyzing data from two indentation techniques—ramp-stress relaxation and load-unload hysteresis tests. Material composition is predictably correlated with viscoelastic model parameters. Model parameters estimated from the tests reveal that elastic modulus E 0 closely approximates the shear modulus for pure gelatin. Fractional-order parameter α and time constant τ vary monotonically with the volume fraction of the material’s fluid component. α characterizes medium fluidity and the rate of energy dissipation, and τ is a viscous time constant. Numerical simulations suggest that the viscous coefficient η is proportional to the energy lost during quasi-static force-displacement cycles, E A . The slope of E A versus η is determined by α and the applied indentation ramp time T r. Experimental measurements from phantom and ex vivo liver data show close agreement with theoretical predictions of the η -{{E}A} relation. The relative error is less than 20% for emulsions 22% for liver. We find that KVFD model parameters form a concise features space for biphasic medium characterization that described time-varying mechanical properties. The experimental work was carried out at the Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA. Methodological development, including numerical simulation and all data analysis, were carried out at the school of Life Science and Technology, Xi’an JiaoTong University, 710049, China.

    The intrinsic vulnerability of groundwater in the Comunidad de Madrid (central Spain) was evaluated using the DRASTIC and GOD indexes. Groundwater vulnerability to nitrate pollution was also assessed using the composite DRASTIC (CD) and nitrate vulnerability (NV) indexes. The utility of these methods was tested by analyzing the spatial distribution of nitrate concentrations in the different aquifers located in the study area: the Tertiary Detrital Aquifer, the Moor Limestone Aquifer, the Cretaceous Limestone Aquifer and the Quaternary Aquifer. Vulnerability maps based on these four indexes showed very similar results, identifying the Quaternary Aquifer and the lower sub-unit of the Moor Limestone Aquifer as deposits subjected to a high risk of nitrate pollution due to intensive agriculture. As far as the spatial distribution of groundwater nitrate concentrations is concerned, the NV index showed the greatest statistical significance ( p < 0.01). This new type of multiplicative model offers greater accuracy in estimations of specific vulnerability with respect to the real impact of each type of land use. The results of this study provide a basis on which to guide the designation of nitrate vulnerable zones in the Comunidad de Madrid, in line with European Union Directive 91/676/EEC.

    En investigaciones previas sobre el acogimiento familiar y la adopción en Ayacucho, se ha podido descubrir cómo los ayacuchanos adquieren y producen relaciones sociales. Mientras negocian creativamente los discursos y espacios construidos simultáneamente por instituciones, comunidades, y estructuras sociales, van adquiriendo nuevas formas de relacionarse. Este artículo discute el proceso opuesto: el deshacerse de relaciones de parentesco, y el proceso social del abandono o alejamiento. Cuando se aleja a una persona de su familia o su comunidad, los que se quedan en ella llegan a entenderse como ciertos tipos de personas. En los estudios de caso discutidos aquí, recopilados a través de una detallada y cuidadosa observación participante y de entrevistas etnográficas grabadas entre 2001 y 2007, se puede ver cómo, después de un alejamiento social, los individuos que alejan se reinterpretan como sujetos que se encuentran superándose o volviéndose modernos, o bien sacrificándose.

    2008-07-08

    The paper aims at proposing some considerations about some recent experiences of research carried out on the theme of earthquake risk mitigation and combining policies and actions of mitigation with urban development strategies. The objective was to go beyond the classical methodological approach aiming at defining a 'technical' evaluation of the earthquake risk through a procedure which can correlate the three 'components' of danger, exposure and vulnerability. These researches experiment, in terms of methodology and application, with a new category of interpretation and strategy: the so-called Struttura Urbana Minima (Minimum urban structure).Actually, the introduction of the Struttura Urbana Minima establishes a different approach towards the theme of safety in the field of earthquake risk, since it leads to a wider viewpoint, combining the building aspect of the issue with the purely urban one, involving not only town planning, but also social and managerial implications.In this sense the constituent logic of these researches is strengthened by two fundamental issues:- The social awareness of earthquake;- The inclusion of mitigation policies in the ordinary strategies for town and territory management. Three main aspects of the first point, that is of the 'social awareness of earthquake', characterize this issue and demand to be considered within a prevention policy:- The central role of the risk as a social production,- The central role of the local community consent,- The central role of the local community capability to planTherefore, consent, considered not only as acceptance, but above all as participation in the elaboration and implementation of choices, plays a crucial role in the wider issue of prevention policies.As far as the second point is concerned, the inclusion of preventive mitigation policies in ordinary strategies for the town and territory management demands the identification of criteria of choice and priorities of intervention and, as a

    The National Science Foundation has funded a five-year High Performance Computing and Communications project at the National Center for Supercomputing Applications (NCSA) for the direct implementation of several of the computing recommendations of the Astronomy and Astrophysics Survey Committee (the "Bahcall report"). This paper is a summary of the project goals and a progress report. The project will implement a prototype of the next generation of astronomical telescope systems - remotely located telescopes connected by high-speed networks to very high performance, scalable architecture computers and on-line data archives, which are accessed by astronomers over Gbit/sec networks. Specifically, a data link has been installed between the BIMA millimeter-wave synthesis array at Hat Creek, California and NCSA at Urbana, Illinois for real-time transmission of data to NCSA. Data are automatically archived, and may be browsed and retrieved by astronomers using the NCSA Mosaic software. In addition, an on-line digital library of processed images will be established. BIMA data will be processed on a very high performance distributed computing system, with I/O, user interface, and most of the software system running on the NCSA Convex C3880 supercomputer or Silicon Graphics Onyx workstations connected by HiPPI to the high performance, massively parallel Thinking Machines Corporation CM-5. The very computationally intensive algorithms for calibration and imaging of radio synthesis array observations will be optimized for the CM-5 and new algorithms which utilize the massively parallel architecture will be developed. Code running simultaneously on the distributed computers will communicate using the Data Transport Mechanism developed by NCSA. The project will also use the BLANCA Gbit/s testbed network between Urbana and Madison, Wisconsin to connect an Onyx workstation in the University of Wisconsin Astronomy Department to the NCSA CM-5, for development of long

    Activated carbons (ACs) have been prepared using chestnut, cedar and walnut wood shavings from furniture industries located in the Comunidad Autónoma de Extremadura (SW Spain). Phosphoric acid (H3PO4) at different concentrations (i.e. 36 and 85 wt.%) has been used as activating agent. ACs have been characterized from the results obtained by N2 adsorption at 77 K. Moreover, the fractal dimension (D) has been calculated in order to determine the AC surface roughness degree. Optimal textural properties of ACs have been obtained by chemical activation with H3PO4 36 wt.%. This is corroborated by the slightly lower values of D for samples treated with H3PO4 85 wt.%.

    A comprehensive study aimed at evaluating the occurrence, significance of concentrations and spatial distribution of priority pollutants (PPs) along the Comunidad Valenciana coastal waters (Spain) was carried out in order to fulfil the European Water Framework Directive (WFD). Additionally, PP concentrations were also analysed in the effluent of 28 WWTPs distributed along the studied area. In coastal waters 36 organic pollutants of the 71 analysed, including 26 PPs were detected although many of them with low frequency of occurrence. Only 13 compounds, which belong to four different classes (VOCs, organochlorinated pesticides, phthalates and tributyltin compounds (TBT)) showed a frequency of occurrence above 20% in coastal waters. In the results obtained until now, octylphenol, pentachlorobenzene, DEHP and TBT exceeded the annual average concentration (EQS-AAC), and only TBT surpassed the maximum allowable concentration (EQS-MAC). The most frequent contaminants determined in coastal waters were also present in WWTP effluents.

    3-Amino-1,2,4-triazole (amitrole) is a widely used pesticide, with many difficulties to be analyzed at the regulatory level in drinking water, because its high solubility in water. This paper describes a simple and fast method for the simultaneous determination of amitrole and atrazin-2-hydroxy, principal degradation product of s-triazines, by capillary zone electrophoresis. Separation and determination of these herbicides in water samples was performed in 0.02 mol l(-1) phosphate buffer at pH 3.2. The method allows determination of the amitrole and atrazin-2-hydroxy in water samples in concentration lower than 100 mug l(-1). The detection limits using a previous preconcentration step of amitrole in Alberche River (Comunidad Autónoma de Madrid, Spain) and drinking water spiked samples was of 4 mug l(-1).

    It is demonstrated that screening mammography programmes reduce breast cancer mortality considerably. Nevertheless, radiology techniques have an intrinsic risk, the most important being the late somatic effect of the induction of cancer. This study was carried out in order to evaluate the risk to the population produced by the Comunidad Valenciana Breast Screening Programme. All the calculations are carried out for two risk models, UNSCEAR 94 and NRPB 93. On the one hand, screening series detriments are investigated as a function of doses delivered and other parameters related to population structure and X ray equipment. On the other hand the radiation induced cancer probability for a woman who starts at 45 years and remains in the programme until 65 years old is calculated as a function of mammography units' doses and average compression breast thickness. Finally, risk comparison between a screening programme starting at 45 years old and another one starting at 50 years old is made.

    A comunidade astronômica brasileira de há muito almeja ter a sua disposição um instrumento científico com o qual possa fazer pesquisa de vanguarda e manter a competitividade científica a nível internacional. Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

    antecedentes: la alta prevalencia de artrosis en los países occidentales, el elevado costo de las intervenciones de artroplastia de cadera y rodilla y las amplias variaciones en la práctica médica generan gran interés por comparar los costos asociados antes y después de la cirugía. Objetivo: conocer el costo de las intervenciones de reemplazo total de cadera y rodilla durante la estancia hospitalaria y al año de seguimiento posterior al alta. material y métodos: estudio multicéntrico y prospectivo efectuado en 15 hospitales de tres comunidades autónomas. La relación entre las variables independientes con el costo de la estancia y costo post-alta, se analizó con modelos multinivel y para agrupar los casos se utilizó la variable "hospital." Las variables independientes fueron: edad, sexo, índice de masa corporal, calidad de vida prequirúrgica (cuestionarios ED-5D, SF-12 y Womac), intervención (cadera-rodilla), índice Charlson, complicaciones, número de camas y dependencia económico-institucional del hospital, comunidad autó-noma y presencia de cuidador. Resultados: el costo promedio por paciente, sin incluir el costo de la prótesis, fue de 4,734 Euros ± 2,136 y el costo del seguimiento post alta de 554 Euros ± 509. Si se incluye el costo de la prótesis, al final del año el costo total asciende a 7,645 Euros ± 2,248. Conclusiones: existe un margen considerable en la reducción de los costos de estancia; más de 44% de la variabilidad observada no está determinada por las condiciones clínicas de los pacientes sino por el comportamiento de los centros hospitalarios.

    Introduccion. El tratamiento de las crisis epilepticas prolongadas requiere disponer de una medicacion de rescate comoda, segura y efectiva. Actualmente, el tratamiento estandar en la comunidad es el diacepam rectal. La introduccion de una solucion bucal de midazolam abre una perspectiva nueva en el tratamiento. Objetivo. Evaluar el coste-efectividad del midazolam bucal respecto al diacepam rectal para los niños con un diagnostico de epilepsia que presentan crisis convulsivas prolongadas en la comunidad en España. Materiales y metodos. Modelo coste-efectividad desde la perspectiva del Sistema Nacional de Salud (SNS) español, con resultados presentados en terminos de costes y años de vida ajustados por calidad. Los datos se obtuvieron de varias fuentes, incluidas las estimaciones de efectividad clinica de un ensayo clinico, de un panel Delphi en España y de una encuesta nacional a padres de niños con epilepsia para determinar las practicas actuales. Resultados. El tratamiento con midazolam bucal produce un ahorro de costes en comparacion con el diacepam rectal. El ahorro para el SNS español es de 5.484 euros por paciente al año. El tratamiento con midazolam bucal ofrece una mejora en la calidad de vida relacionada con la salud. Esto, unido al ahorro de costes, hace que el midazolam bucal sea dominante frente al diacepam rectal en todos los escenarios examinados. Conclusion. Los resultados del modelo muestran que el midazolam bucal es mas coste-efectivo que el diacepam rectal debido a una reduccion en la necesidad de llamadas a la ambulancia y estancias en el hospital, asi como a una mejora en la calidad de vida relacionada con la salud.

    Apolipoprotein A4 (apoA4) plays a role in intestinal lipid absorption. Several experimental interventions have shown that common variations at residues 347 (Thr --> Ser) and 360 (Gln --> His) on apoA4 are associated with differences in plasma lipid response to dietary fat; however, association studies between these variants and plasma lipid concentrations in populations reveal mixed results. We examined the effects of these polymorphisms in 758 randomly selected subjects (mean age 36.7+/-9.5 years) from 2 Spanish regions differing in latitude and fat intake: Aragón and Comunidad Valenciana. Subjects were matched one to one by sex and age. Frequencies for the less common alleles were similar in both regions: 0.096 (95% CI: 0.111-0.081) for codon 360 and 0.196 (95% CI: 0.216-0.176) for codon 347. In men and women there was no association between the codon 360 polymorphism and total cholesterol or triglyceride levels. However, subjects carrying the 360His allele had low-density lipoprotein (LDL) cholesterol concentrations statistically lower than homozygotes for the 360Gln allele, even after further adjustment for sex, age, region, body mass index, and APOE polymorphism (p = 0.043). The less common allele at codon 347 (the 347Ser allele) was associated with increased LDL-cholesterol concentrations with a clear gene-dosage effect after multivariate adjustment (p = 0.029). Although these polymorphisms showed no heterogeneity by geographic region, the magnitude of the effect was higher in subjects from Aragón compared with the Comunidad Valenciana, suggesting a possible influence of the higher fat intake in Aragón. In the combined association analysis subjects with the 360Gln/347Ser pseudohaplotype had the highest LDL-cholesterol concentrations, supporting the antagonistic effect between the 360His and the 347Ser alleles on this trait.

    Objetivo: Evaluar la prescripcion potencialmente inapropiada (PPI) mediante la aplicacion de los criterios Beers (version 2012) y STOPP (version 2008) en pacientes mayores, polimedicados y residentes en la comunidad. Metodos: A partir de la informacion recogida en los datos de facturacion de recetas y de las historias clinicas electronicas se selecciono una muestra de 223 pacientes de 65 o mas anos, que tomaban simultaneamente 10 o mas medicamentos/dia. Se aplicaron separadamente los criterios de Beers y STOPP y se compararon los resultados obtenidos con ambos metodos. Resultados: Un total de 141 pacientes (63,2%) presentaban al menos un criterio de Beers. Los dos criterios de Beers independientes del diagnostico observados con mas frecuencia fueron el uso de benzodiazepinas y el uso de antiinflamatorios no esteroideos no selectivos de ciclooxigenasa-2. Con respecto a los criterios de Beers considerando el diagnostico, los mas frecuentes fueron el uso de anticolinergicos en pacientes con sintomas del tracto urinario inferior o con hiperplasia benigna de prostata y el uso de benzodiazepinas, antipsicoticos, zolpidem o antihistaminicos H2, en pacientes con demencia o deterioro cognitivo. Un total de 165 (73,9%) pacientes tenian al menos una PPI segun los criterios STOPP. La duplicidad terapeutica y el uso prolongado de benzodiazepinas de vida media larga fueron los dos criterios STOPP mas comunes. Discusion: Nuestro estudio identifico una alta frecuencia de PPI en pacientes mayores, polimedicados y residentes en la comunidad. La aplicacion simultanea de los criterios de Beers y STOPP constituye una herramienta util para mejorar la prescripcion en este grupo de poblacion.

    1991-11-01

    This thesis involved the construction of (1) a grammar that incorporates knowledge on base invariancy and secondary structure in a molecule and (2) a parser engine that uses the grammar to position bases into the structural subunits of the molecule. These concepts were combined with a novel pinning technique to form a tool that semi-automates insertion of a new species into the alignment for the 16S rRNA molecule (a component of the ribosome) maintained by Dr. Carl Woese`s group at the University of Illinois at Urbana. The tool was tested on species extracted from the alignment and on a group of entirely new species. The results were very encouraging, and the tool should be substantial aid to the curators of the 16S alignment. The construction of the grammar was itself automated, allowing application of the tool to alignments for other molecules. The logic programming language Prolog was used to construct all programs involved. The computational linguistics approach used here was found to be a useful way to attach the problem of insertion into an alignment.

    Gibbs, K. P.; Bowhill, S. A.

    1983-01-01

    Turbulent scatter from he mesosphere is observed using the Urbana coherent-scatter radar. The variation in signal-to-noise ratio as a function of time-of-day is examined. The origin of scattering regions is investigated by comparing the variations in scattered power and Doppler velocity. Nighttime echoes are shown for periods of enhanced electron concentration. The spectrum of the returned signal is studied with a resolution of ten seconds. Spectral information is used to increase altitude resolution and observe the motion of scatterers. The expected variation in signal-to-noise ratio with solar flux is observed. It is found that variations in the scattered power generally do not correspond to the gravity waves which are simultaneously observed. Turbulent layers are observed at altitudes with high shear in the horizontal velocity and at altitudes with low shear. The ten-second resolution is necessary to distinguish meteor echoes from echoes produced by the advection of a scattering layer through the radar beam.

  10. Construction and Gluing of G10 Frames and Printed Circuit Boards to be used in COMPASS Drift Chamber 5

    NASA Astrophysics Data System (ADS)

    Britto, Vivek

    2014-09-01

    COMPASS is a fixed-target nuclear physics experiment at CERN which explores the internal structure of the proton. One specific area of research is the measurement of single transverse spin asymmetries in pion beam induced Drell-Yan production of muon pairs from polarized proton targets. The spin dependence of the Drell-Yan cross section may be indicative of contributions from quark orbital angular momentum to the spin of the proton. The University of Illinois at Urbana-Champaign (UIUC), in collaboration with institutes in Taiwan, France, Italy and Germany, is designing and building a new drift chamber, DC5, to replace an aging detector in the COMPASS spectrometer. The frames supporting the anode wires and cathode planes in DC5 are constructed from G10, a fiberglass-epoxy composite. Once the individual sides of each frame have been milled, they are glued together at the corner lap joints. Additionally, printed circuit boards are glued to the anode frames, where sense and field wires will later be soldered. To maintain optimal operation of the drift chamber, the frame thickness after gluing must be within 50 μm of the design value. This presentation will explain the methods employed to achieve the required tolerances for this precision gluing process.

    The PHENIX collaboration at relativistic heavy ion collider (RHIC) will measure the maximal parity violating W asymmetries in polarized proton-proton collisions at high transverse momentum in order to make the most precise measurement of the quark and the anti-quark polarizations of the proton. For this measurement, the collaboration is installing resistive plate chambers (RPCs) similar to the CMS Endcap RPCs in the two existing muon spectrometers. In these proceedings, we shall discuss the research and development (R&D) that has been done by the collaboration in order to both understand and develop RPC technology. The R&D has been carried out at Georgia State University, the University of Colorado at Boulder, and the University of Illinois at Urbana-Champaign with many other institutions contributing as well; each university has focused on the different aspects of the RPCs. Georgia State has focused on detector design, performance, and stability; Colorado has tested the front end electronics and termination schemes; Illinois has performed position resolution studies as well as two-dimensional efficiency scans of RPCs. Additionally, a cosmic ray teststand for final gap QA is currently operational at Brookhaven National Laboratory (BNL).

    We examined how leaf litter of alien invasive honeysuckle (Lonicera maackii Rupr.) either alone or in combination with leaf litter of one of two native tree species, sugar maple (Acer saccharum Marshall) and northern red oak (Quercus rubra L.), affects the ecology of Culex restuans Theobald, Ochlerotatus triseriatus Say, and Ochlerotatus japonicus Theobald. Experimental mesocosms containing single species litter or a mixture of honeysuckle and one of two native tree species litter were established at South Farms and Trelease Woods study sites in Urbana, IL, and examined for their effect on 1) oviposition site selection by the three mosquito species, and 2) adult production and body size of Oc. triseriatus and Oc. japonicus. There were no significant effects of study site and leaf treatment on Oc. japonicus and Oc. triseriatus oviposition preference and adult production. In contrast, significantly more Cx. restuans eggs rafts were collected at South Farms relative to Trelease Woods and in honeysuckle litter relative to native tree species litter. Significantly larger adult females of Oc. japonicus and Oc. triseriatus were collected at South Farms relative to Trelease Woods and in honeysuckle litter relative to native tree species litter. Combining honeysuckle litter with native tree species litter had additive effects on Cx. restuans oviposition preference and Oc. japonicus and Oc. triseriatus body size, with the exception of honeysuckle and northern red oak litter combination, which had antagonistic effects on Oc. triseriatus body size. We conclude that input of honeysuckle litter into container aquatic habitats may alter the life history traits of vector mosquito species.

    The Department of Chemistry at the University of Illinois at Urbana-Champaign offers two courses in astrochemistry, one lecture (Chem 450) and one laboratory (Chem 451). Both courses present the opportunity for advanced undergraduate and graduate students to learn about various spectroscopic concepts as they are applied toward an exotic subject, astrochemistry. In the lecture course, each student devotes a substantial fraction of the course work to one of the known astromolecules, building a wiki page for it during the semester, presenting a brief oral description about it in class, and then finally writing a paper about it. The course covers electronic, vibrational, and rotational spectroscopy, along with Einstein coefficients, line widths, and the interpretation of actual astronomical spectra. It also covers relevant reactions and reaction networks. Students learn to use pgopher for modeling rotational spectra. The lab course focuses on the methylidyne radical (CH). It begins with its chemistry and spectroscopy and then moves on to laboratory study of its electronic spectrum as observed in a butane flame and then collected with the university's 12" f/15 Brashear refracting telescope in the campus observatory built in 1896. Students learn to use IGOR to reduce CCD data.

    A new pulsed-arc-heated hypersonic wind tunnel facility, designated as ACT-1 (Arc-heated Combustion Test-rig 1), has been developed and built at the University of Notre Dame in collaboration with the University of Illinois at Urbana-Champaign and Alta S.p.A. The aim of the design is to provide a suitable test platform for experimental studies on supersonic and hypersonic turbulent combustion phenomena. ACT-1 is composed of a high temperature gas-generator system and a model scramjet combustor that is installed in an open-type vacuum test section of the wind tunnel facility. The gas-generator is designed to produce high-enthalpy (stagnation temperature  =  2000 K-3500 K) hypersonic flows for a run time up to 1 s. The supersonic combustor section is composed of a compression ramp (scramjet inlet), an internal flow channel of constant cross-section, a fuel jet nozzle, and a flame holder (wall cavity). The facility allows three-way optical accesses (top and sides) into the supersonic combustor to enable various advanced optical and laser diagnostics. In particular, planar laser Rayleigh scattering (PLRS), high-speed schlieren imaging and OH-planar laser induced fluorescence (OH-PLIF) have successfully been implemented to visualize the turbulent flows and flame structures at high speed flight conditions.

    Drinking water distribution systems (DWDSs) harbor the microorganisms in biofilms and suspended communities, yet the diversity and spatiotemporal distribution have been studied mainly in the suspended communities. This study examined the diversity of biofilms in an urban DWDS, its relationship with suspended communities and its dynamics. The studied DWDS in Urbana, Illinois received conventionally treated and disinfected water sourced from the groundwater. Over a 2-year span, biomass were sampled from household water meters (n=213) and tap water (n=20) to represent biofilm and suspended communities, respectively. A positive correlation between operational taxonomic unit (OTU) abundance and occupancy was observed. Examined under a 'core-satellite' model, the biofilm community comprised 31 core populations that encompassed 76.7% of total 16 S rRNA gene pyrosequences. The biofilm communities shared with the suspended community highly abundant and prevalent OTUs, which related to methano-/methylotrophs (i.e., Methylophilaceae and Methylococcaceae) and aerobic heterotrophs (Sphingomonadaceae and Comamonadaceae), yet differed by specific core populations and lower diversity and evenness. Multivariate tests indicated seasonality as the main contributor to community structure variation. This pattern was resilient to annual change and correlated to the cyclic fluctuations of core populations. The findings of a distinctive biofilm community assemblage and methano-/methyltrophic primary production provide critical insights for developing more targeted water quality monitoring programs and treatment strategies for groundwater-sourced drinking water systems.

    2002-06-01

    The overall objective of this three-year collaborative project between the University of Illinois at Urbana-Champaign (UIUC) and Battelle Pacific Northwest National Laboratory (PNNL) was to develop a framework which would incorporate computationally efficient representations of the latest knowledge concerning science, scenarios, and technical change, to allow for the effective and efficient analysis of possible future strategies to control methane. As part of this research project, we developed a model that takes into account more explicit treatment of the mechanisms controlling each important methane regional source and sink to study non-linear effects involved in methane chemistry in the atmosphere. On the policy front, we developed the relationship between economics and climatic impacts of methane emission reductions. On the application front, we applied the newly developed advanced methane modeling capabilities to study the effects of a wide range of possible scenarios of future methane emissions on climate and to examined the costs associated with achieving specific greenhouse gas reduction targets for a range of emission pathways. The significant findings from the DOE supported study are outlined.

  20. Long-term analysis of a full-scale activated sludge wastewater treatment system exhibiting seasonal biological foaming.

    2006-03-01

    The seasonal accumulation of biological foam on the activated sludge system of the Urbana-Champaign Sanitary District Northeast (UCSD-NE) wastewater treatment plant was investigated over an 8-year period by statistical analyses including path analysis, multivariate regression, and principal component analysis. Results of these analyses suggested that variation in the activated sludge reactor temperature and the use of a stream bypassing the primary clarifier were the two main factors determining the observed temporal foam profile. Characterization of the primary clarifier influent and effluent suggested the involvement of high lipid loading rates from the bypass stream in foam accumulation. In light of these results, it is hypothesized that increasing temperatures and lipid loading rates are responsible for foam formation through the same mechanism: the foam-forming microbial population is specialized in consuming lipids, substrates classified as slowly degradable. When the temperature increases, the rate of lipid hydrolysis becomes sufficiently high for this population to become abundant, accumulate on the surfaces of the aeration basins, and cause biological foaming.

    2012-03-07

    This project was focused on simulations of core-collapse supernovae on parallel platforms. The intent was to address a number of linked issues: the treatment of hydrodynamics and neutrino diffusion in two and three dimensions; the treatment of the underlying nuclear microphysics that governs neutrino transport and neutrino energy deposition; the understanding of the associated nucleosynthesis, including the r-process and neutrino process; the investigation of the consequences of new neutrino phenomena, such as oscillations; and the characterization of the neutrino signal that might be recorded in terrestrial detectors. This was a collaborative effort with Oak Ridge National Laboratory, State University of New York at Stony Brook, University of Illinois at Urbana-Champaign, University of California at San Diego, University of Tennessee at Knoxville, Florida Atlantic University, North Carolina State University, and Clemson. The collaborations tie together experts in hydrodynamics, nuclear physics, computer science, and neutrino physics. The University of Washington contributions to this effort include the further development of techniques to solve the Bloch-Horowitz equation for effective interactions and operators; collaborative efforts on developing a parallel Lanczos code; investigating the nuclear and neutrino physics governing the r-process and neutrino physics; and exploring the effects of new neutrino physics on the explosion mechanism, nucleosynthesis, and terrestrial supernova neutrino detection.

    This report describes work carried out under a Sandia National Laboratories Excellence in Engineering Fellowship in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. Our research group (at UIUC) is developing a intelligent robot, and attempting to teach it language. While there are many aspects of this research, for the purposes of this report the most important are the following ideas. Language is primarily based on semantics, not syntax. To truly learn meaning, the language engine must be part of an embodied intelligent system, one capable of using associative learning to form concepts from the perception of experiences in the world, and further capable of manipulating those concepts symbolically. In the work described here, we explore the use of hidden Markov models (HMMs) in this capacity. HMMs are capable of automatically learning and extracting the underlying structure of continuous-valued inputs and representing that structure in the states of the model. These states can then be treated as symbolic representations of the inputs. We describe a composite model consisting of a cascade of HMMs that can be embedded in a small mobile robot and used to learn correlations among sensory inputs to create symbolic concepts. These symbols can then be manipulated linguistically and used for decision making. This is the project final report for the University Collaboration LDRD project, 'A Robotic Framework for Semantic Concept Learning'.

    Data on power, correlation time, and velocity were obtained at the Urbana radar using microcomputer and a single floppy disk drive. This system includes the following features: (1) measurement of the real and imaginary components of the received signal at 20 altitudes spaced by 1.5 km; (2) coherent integration of these components over a 1/8-s time period; (3) continuous real time display of the height profiles of the two coherently integrated components; (4) real time calculation of the 1 minute averages of the power and autocovariance function up to 6 lags; (5) output of these data to floppy disk once every 2 minutes; (6) display of the 1 minute power profiles while the data are stored to the disk; (7) visual prompting for the operator to change disks when required at the end of each hour of data; and (8) continuous audible indication of the status of the interrupt service routine. Accomplishments were enabled by two developments: the use of a new correlation algorithm and the use of the FORTH language to manage the various low level and high level procedures involved.

    The MODIS Reprojection Tool (MRT) is designed to help individuals work with MODIS Level-2G, Level-3, and Level-4 land data products. These products are referenced to a global tiling scheme in which each tile is approximately 10° latitude by 10° longitude and non-overlapping (Fig. 9.1). If desired, the user may reproject only selected portions of the product (spatial or parameter subsetting). The software may also be used to convert MODIS products to file formats (generic binary and GeoTIFF) that are more readily compatible with existing software packages. The MODIS land products distributed by the Land Processes Distributed Active Archive Center (LP DAAC) are in the Hierarchical Data Format - Earth Observing System (HDF-EOS), developed by the National Center for Supercomputing Applications at the University of Illinois at Urbana Champaign for the NASA EOS Program. Each HDF-EOS file is comprised of one or more science data sets (SDSs) corresponding to geophysical or biophysical parameters. Metadata are embedded in the HDF file as well as contained in a .met file that is associated with each HDF-EOS file. The MRT supports 8-bit, 16-bit, and 32-bit integer data (both signed and unsigned), as well as 32-bit float data. The data type of the output is the same as the data type of each corresponding input SDS.

    This presentation provides a high level overview of the Large-Scale Low-Boom Inlet Test and was presented at the Fundamental Aeronautics 2011 Technical Conference. In October 2010 a low-boom supersonic inlet concept with flow control was tested in the 8'x6' supersonic wind tunnel at NASA Glenn Research Center (GRC). The primary objectives of the test were to evaluate the inlet stability and operability of a large-scale low-boom supersonic inlet concept by acquiring performance and flowfield validation data, as well as evaluate simple, passive, bleedless inlet boundary layer control options. During this effort two models were tested: a dual stream inlet intended to model potential flight hardware and a single stream design to study a zero-degree external cowl angle and to permit surface flow visualization of the vortex generator flow control on the internal centerbody surface. The tests were conducted by a team of researchers from NASA GRC, Gulfstream Aerospace Corporation, University of Illinois at Urbana-Champaign, and the University of Virginia

    This work reports results for (i) the elastic electromagnetic form factors of the trin- of ucleons; (ii) the nuclear response functions of interest in ~ experiments, 3 He(~e; e 0 ) experiments, at VERSITY excitation energies below the deuteron breakup threshold; (iii) the astrophysical ark S-factor for proton weak capture on 3 He (the hep reaction). The initial and nal using state wave functions are calculated using the correlated hyperspherical harmonics onsisting method, from a realistic Hamiltonian consisting of the Argonne v 18 two-nucleon uclear and Urbana IX three-nucleon interactions. The nuclear electroweak charge and ts. current operators include one- and many-body components. The predicted mag- netic form factor of 3 H, charge form factors and static properties of both 3 H and ntal 3 He, are in satisfactory agreement with the experimental data. However, the po- sition of the zero in the magnetic form factor of 3 He is underpredicted by theory. disintegration The calculated nuclear response functions in 3 He electrodisintegration at thresh- er old are in good agreement with the experimental data, which have however rather s large errors. Finally, the astrophysical S-factor for the hep reaction is predicted ortant ' 4.5 larger than the value adopted in the standard-solar-model, with important consequences for the solar neutrino spectrum measured by the Super-Kamiokande collaboration.

    2017-02-01

    The single-particle potentials and other properties at absolute zero temperature in isospin asymmetric nuclear matter are investigated in the frame of an extended Brueckner theory. Also thermal quantities are calculated in asymmetric nuclear matter using CD-Bonn potential and the Urbana three-body forces (3BF). Also, the effects of the hole-hole contributions are investigated within the self-consistent Greens function approach. The inclusion of 3BF or the hole-hole contributions improves the predicted saturation property of symmetric nuclear matter within the Brueckner-Hartree-Fock approach and it leads to a significant stiffening of the density dependence of symmetry energy at high densities but the exact saturation point is not reproduced. This is of great importance in astrophysical calculation. A phenomenological term simulating the three-body interaction is introduced to assure the empirical saturation property. The hot properties of asymmetric nuclear matter such as the internal energy and the pressure are analyzed using T2-approximation method at low temperatures.

  9. Introduction to Session 1A: Feedstock Genomics and Development

    NASA Astrophysics Data System (ADS)

    Vermerris, Wilfred

    Genomics research aimed at improving bioconversion properties of feedstocks received a major impetus as a result of the Feedstock Genomics program jointly operated by the U.S. Department of Energy (DOE) and the U.S. Department of Agriculture (USDA). In addition, oil company BP established the Energy Biosciences Institute in collaboration with the University of California-Berkeley, Lawrence Berkeley National Laboratory, and the University of Illinois in Urbana-Champaign. This was followed later on in the year by the establishment of three DOE-funded bioenergy centers. The need to switch from petroleum-based duels to biofuels was underscored by the report of Working Group II of the United Nations-sponsored International Panel on Climate Change (IPCC), in which the wide-spread effects of greenhouse gas emissions on the global climate were presented. IPCC and former U.S. vice-president Al Gore received the 2007 Nobel Peace Prize for their efforts to quantify and disseminate the effects of global warming.

    2010-11-01

    This report documents the results of a Strategic Partnership (aka University Collaboration) LDRD program between Sandia National Laboratories and the University of Illinois at Urbana-Champagne. The project is titled 'Data-Driven Optimization of Dynamic Reconfigurable Systems of Systems' and was conducted during FY 2009 and FY 2010. The purpose of this study was to determine and implement ways to incorporate real-time data mining and information discovery into existing Systems of Systems (SoS) modeling capabilities. Current SoS modeling is typically conducted in an iterative manner in which replications are carried out in order to quantify variation in the simulation results. The expense of many replications for large simulations, especially when considering the need for optimization, sensitivity analysis, and uncertainty quantification, can be prohibitive. In addition, extracting useful information from the resulting large datasets is a challenging task. This work demonstrates methods of identifying trends and other forms of information in datasets that can be used on a wide range of applications such as quantifying the strength of various inputs on outputs, identifying the sources of variation in the simulation, and potentially steering an optimization process for improved efficiency.

    Identification and characterization of dissolved organic phosphorus (DOP) present in the waters of Crystal Lake in Urbana, IL, and Walker Branch at Oak Ridge, TN using ultrafiltration (UF) and reverse osmosis (RO) concentration methods, high performance liquid chromatography (HPLC), and Phosphorus-31 Fourier Transform Nuclear Magnetic Resonance spectroscopy (31P FT-NMR) is reported. UF and RO membrane methods enabled a several thousand fold concentration of the DOP, which was necessary for detection by HPLC and 31P FT-NMR. The behavior and recovery of aquatic DOP compounds with several UF and RO membranes were examined and a membrane configuration consisting of a 30 K dalton UF membrane, a 1 K dalton UF membrane, and a RO 95 percent NaCl rejection membrane, in series, was used to concentrate and fractionate DOP according to its molecular size. Extensive concentration with UF and RO membrane methods appear to produce aggregation of dissolved organic carbon compounds with the concurrent adsorption or incorporation of DOP.

    This report describes similarities and differences between undergraduate and graduate engineering science students in the context of two general aspects of the educational experience. First, we explore the extent to which students differ regarding the factors that lead to the choice of becoming an engineer or a scientist, current satisfaction with that choice, and career-related goals and objectives. Second, we look at the technical communication practices, habits, and training of engineers and science (Physics) students. The reported data were obtained from a survey of students enrolled in the College of Engineering at the University of Illinois at Urbana-Champaign, Bowling Green State University, and Texas A&M University. The survey was undertaken as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. Data are reported for the following categories: student demographics; skill importance, skill training, and skill helpfulness; collaborative writing; computer and information technology use and importance, use of electronic networks; use and importance of libraries and library services; use and importance of information sources and products; use of foreign technical reports; and foreign language (reading and speaking) skills.

    This project responds to the need to identify the knowledge, skills, and expertise required by health sciences librarians in the future and to devise mechanisms for providing this requisite training. The approach involves interdisciplinary multiinstitutional alliances with collaborators drawn from two graduate schools of library and information science (University of Illinois at Urbana-Champaign and Indiana University) and two medical schools (University of Illinois at Chicago and Washington University). The project encompasses six specific aims: (1) investigate the evolving role of the health sciences librarian; (2) analyze existing programs of study in library and information science at all levels at Illinois and Indiana; (3) develop opportunities for practicums, internships, and residencies; (4) explore the possibilities of computing and communication technologies to enhance instruction; (5) identify mechanisms to encourage faculty and graduate students to participate in medical informatics research projects; and (6) create recruitment strategies to achieve better representation of currently underrepresented groups. The project can serve as a model for other institutions interested in regional collaboration to enhance graduate education for health sciences librarianship. PMID:8913560

    2007-01-01

    Compost samples from two composting facilities, the Urbana (Illinois) Landscape Recycling Center (ULRC) and Illinois State University (ISU), were selected to examine the effect of compost age on atrazine removal from solution. The ULRC samples were made from yard waste without an additional nitrogen source. The ISU samples were made from yard waste or sawdust with the addition of manure. The 6-month-old ULRC compost had the greater capacity to remove atrazine from solution, which we attributed to its greater organic carbon content. The addition of nitrate into ULRC compost could influence the extent of atrazine removal, but did not have a significant impact on atrazine removal when applied to ISU compost, probably because manure was added to the yard waste to produce the compost. For both ULRC and ISU samples, the presence of sodium azide inhibited atrazine removal, suggesting that microbial activity contributed to the atrazine removal. Metabolic analysis demonstrated that hydroxyatrazine was the major identified metabolite that accumulated in solution before significant ring mineralization could occur. When compared with the ISU compost, the ULRC compost sample had a greater capacity to remove atrazine from solution during the 120 days of study because of the larger humic acid content. The experimental results suggested that less-mature compost may be better suited for environmental applications such as removing atrazine from tile-drainage waters. ?? 2006 Elsevier B.V.

    We describe progress in the development of new materials for portable, room-temperature, gamma-radiation detection at Pacific Northwest National Laboratory at the Hanford Site in Washington State. High Z, high resistivity, amorphous semiconductors are being designed for use as solid-state detectors at near ambient temperatures; principles of operation are analogous to single-crystal semiconducting detectors. Amorphous semiconductors have both advantages and disadvantages compared to single crystals, and this project is developing methods to mitigate technical problems and design optimized material for gamma detection. Several issues involved in the fabrication of amorphous semiconductors are described, including reaction thermodynamics and kinetics, the development of pyrolytic coating, and the synthesis of ingots. The characterization of amorphous semiconductors is described, including sectioning and polishing protocols, optical microscopy, X-ray diffraction, scanning electron microscopy, optical spectroscopy, particle-induced X-ram emission, Rutherford backscattering, and electrical testing. Then collaboration with the University of Illinois at Urbana-Champaign is discussed in the areas of Hall-effect measurements and current voltage data. Finally, we discuss the strategy for continuing the program.

    The positive intrinsic negative (PIN) diode switch which is designed to protect the receiver from burnout or damage on transmission and channel the echo signal to the receiver on reception is outlined. The receiver must be protected firmly. A schematic diagram of a transformer rectifier (TR-ATR) switch for the Urbana Radar is shown. The T/R switch consists of a half wavelength coaxial cavity with tuning condenser and PIN diodes. Two UM4300 PIN diodes were mounted between the inner and outer conductor. The dc biasing voltage required for the PIN diodes is supplied by a control circuit. On transmission, the PIN diodes are forward biased to about 0.5 amperes. On reception, about 10 volts reverse voltage is applied to the diodes, which produces an initial reverse current to speed the recovery time. The T/R switch characteristics are estimated and the result of testing at different peak transmitter powers from 410 kW to 1500 kW is shown.

    2011-01-01

    The muon-capture reactions H2(μ-,νμ)nn and He3(μ-,νμ)H3 are studied with conventional or chiral realistic potentials and consistent weak currents. The initial and final A=2 and A=3 nuclear wave functions are obtained from the Argonne v18 or chiral next-to-next-to-next-to leading order (N3LO) two-nucleon potential, in combination with, respectively, the Urbana IX or chiral next-to-next-to leading order (N2LO) three-nucleon potential in the case of A=3. The weak current consists of polar- and axial-vector components. The former are related to the isovector piece of the electromagnetic current via the conserved-vector-current hypothesis. These and the axial currents are derived either in a meson-exchange or in a chiral effective field theory (χEFT) framework. There is one parameter (either the N-to-Δ axial coupling constant in the meson-exchange model, or the strength of a contact term in the χEFT model) that is fixed by reproducing the Gamow-Teller matrix element in tritium β decay. The model dependence relative to the adopted interactions and currents (and cutoff sensitivity in the χEFT currents) is weak, resulting in total rates of 392.0±2.3 s-1 for A=2, and 1484±13 s-1 for A=3, where the spread accounts for this model dependence.

    For extreme ultraviolet lithography (EUVL) to become a high volume manufacturing technology for integrated circuit manufacturing, the cleanliness of the system, especially the photomask, is of high importance. For EUV photomasks, which cannot be protected from contamination by the use of a pellicle, an effective and quick cleaning technology needs to be ready in order to maintain wafer throughput. There are challenges to extend current wet cleaning technologies to meet the future needs for damage-free and high efficiency mask cleaning. Accordingly, a unique process for cleaning particulates from surfaces, specifically photomasks as well as wafers, has been evaluated at the University of Illinois Urbana-Champaign. The removal technique utilizes a high density plasma source as well as pulsed substrate biases to provide for removal. Helium is used as the primary gas in the plasma, which under ionization, provides for a large density of helium metastable atoms present in the plasma. These metastable helium atoms have on the order of 20 eV of energy which can transfer to particles on the substrate to be cleaned. When the substrate is under a small flux of ion bombardment, these bonds then remain broken and it is theorized that this allows the particles to be volatilized for their subsequent removal. 100 % particle removal efficiency has been obtained for 30 nm, 80 nm, and 200 nm polystyrene latex particles. In addition, removal rate has been correlated with helium metastable population density determined by optical emission spectroscopy.

    The definition of the SI unit of mass is based on the international prototype of the kilogram, created in 1879 [1]. In the next years, metrologists will redefine the kilogram in relation to fundamental physical constants [2]. Intended for a general audience, the forthcoming documentary, The State of the Unit: The Kilogram, presents the history of the kilogram, interviews with researchers at national metrology institutes in the U.S., France, and Germany, and everyday mass measurement activities at varying scales. Excerpts of the film will be shown, and followed by a discussion with the filmmaker about the project to date. This film is supported in part by the Materials Computation Center at the University of Illinois at Urbana-Champaign, the California Institute of the Arts, Valencia, California, and La F'emis, Paris, France.[4pt] [1] The Kilogram and Measurements of Mass and Force, Z.

    The results of testing two technologies based on gas microplasmas for the generation of UV-visible light is detailed. A microcavity device from the University of Illinois at Champaign-Urbana have been delivered with an Ar/D II gas mixture. Emission from the Ar/Ne as well as an Ar/D II eximer in the 250-400nm range, as well as argon lines in the visible and near infrared, are measured. Development of addressing arrays is discussed as is the potential of emission in other wavebands with other gas species. A 100x40 array of plasmaspheres combined with electronics capable of projecting images at 1000 Hz with 10 bits of grayscale resolution has been built and tested. This system, built by Imaging Systems Technology (IST), is capable of accepting DVI output from a HWIL system and projecting UV from a gas captured in the spheres. This array uses an argon neon gas mixture to produce UV, visible and near infrared light. Performance data discussed for both arrays include: maximum and minimum brightness, uniformity, spectral content, speed, linearity, crosstalk, resolution, and frame rate. Extensions of these technologies to larger arrays with wider spectral bandwidth for use in multispectral projectors are discussed.

    Two new imaging Fabry-Perot Interferometers (FPIs) have been deployed to measure neutral winds and temperatures from observations of the 630.0-nm thermospheric emission. The FPIs provide accurate estimates of the horizontal neutral wind and temperatures in the early evening when the emission is brightest, with accuracies deteriorating after that time. These two FPIs were initially tested for approximately one year at a field site located near the University of Illinois at Urbana-Champaign. They were then deployed to northeastern Brazil, where they have been operating since September 2009. We present case studies from these two deployments demonstrating the capabilities of these instruments. Additionally, we present monthly averaged data of the winds and temperatures as functions of local time and compare these averages to the results obtained from two versions of the horizontal wind model (HWM93, HWM07) and the most recent version of the Mass-Spectrometer-Incoherent-Scatter model (NRLMSISE-00). These comparisons are used to study the accuracy of the climatological models, especially during the recent deep solar minimum corresponding to the FPI measurements obtained from Brazil.

    The CRESST experiment looks for evidence of dark matter particles colliding with nuclei in CaWO4, using cryogenic bolometers sensitive to energy deposition ˜ 10 keV with a few percent accuracy. Calibration of the energy deposited in the phonon system depends upon the details of the evolution of the non-equilibrium energy in the CaWO4 absorber. Our phonon images sensitively measure variations in angular phonon flux, providing key information about the elastic constants and scattering rates that determine the energy evolution. Phonon pulses, created by focused photoexcitation of a 150 nm Cu film, are detected after propagation through 3 mm of CaWO4. The 20 ns Ar-ion laser pulse creates a localized (10-3 mm^2) source of 10-20 K blackbody phonons. The sample is at 2 K. Our images show that the elastic constants derived from ultrasonic velocities along high symmetry axes do not accurately predict the total phonon flux along non-symmetry directions. We present new data on the dependence of phonon flux on excitation level and discuss the influence of isotope and anharmonic decay on the shape of phonon pulses in these ultrapure samples.

    2008-12-01

    The Environmental Molecular Sciences Laboratory at PNNL, in collaboration with the University of Illinois at Champaign-Urbana, has developed a microfluidics capability to investigate the effects of fluid flow and transport at the microscale. Currently the EMSL houses the Subsurface Flow and Transport Laboratory (SFTL) in which EMSL Users have the opportunity to conduct column- and intermediate-scale research. The new Microfluidics Flow and Transport Laboratory (MFTL) will address fundamental scaling issues associated with fluid flow and reactive transport from both a combined experimental and theoretical approach at the micron scale, bridge the gap in experimental capabilities from the molecular scale within EMSL to the laboratory scales currently available in the SFTL, and permit simultaneous spatially and time resolved spectroscopic examination of geochemical and/or biogeochemical processes. Micromodels are two- dimensional representations of porous media etched in into silicon wafers, glass or polymers. Better control of pore network geometry is generally obtained by etching silicon. Pore sizes are typically on the order of tens of microns, but can be configured to be both smaller and larger. Fluid injection occurs with low-pulsation, high-precision syringe pumps. Images are obtained with an inverted fluorescent microscope. In this presentation, the new laboratory will be described and the mechanisms of user access will be explained.

  7. Stardial: an Autonomous Astronomical Camera on the World Wide Web

    1997-11-01

    We describe the use of an autonomous astronomical camera, called ``Stardial,'' for undergraduate instruction. Stardial delivers images of the night sky nearly in real-time to the world wide web (www.astro.uiuc.edu/~stardial/). The world wide web (WWW) interface is robust, inexpensive, and accommodates many students asynchronously with respect to the instructor(s). The guiding philosophy is to provide students with authentic astronomical data so that they may learn about science by doing it themselves. Students respond favorably to the opportunity to learn from their own experiences with authentic data, complete with its irregularities and its surprises. Stardial has been operational for one academic year (1996-97) at the University of Illinois at Urbana-Champaign. In this paper we describe Stardial's instrumentation, some of the curriculum based upon Stardial's unique data, and the experiences of students who have used Stardial. We conclude with possible research topics using Stardial data and with a brief look to the future of remote laboratories. (SECTION: Astronomical Instrumentation) The name ``Stardial'' derives from the fact that like a sundial, Stardial is a stationary device placed outside 24 hours a day, and that both depend on and make evident the rotation of the Earth. A sundial operates with sunlight, while Stardial operates with starlight. There the similarity ends.

    We have completed a wide-angle imaging survey of the entire southern sky (δ < +10 degrees) at 656.3 nm wavelength, the Hα emission line of hydrogen. Each image of the survey covers an area of the sky 13 degrees square at an angular resolution of approximately one arcminute, and reaches a sensitivity level of 0.5 Rayleigh (3 x 10-18 erg cm-2 s-1 arcsec-2 ), corresponding to an emission measure of 1 cm-6 pc, and to a brightness temperature for microwave free-free emission of 3 μ K at 30 GHz. The survey was done with a CCD detector, a commercial camera lens, and narrow-band interference filters, mounted on a robotic telescope platform located at Cerro Tololo Inter-American Observatory in Chile. This work was supported by grants from Las Cumbres Observatory, NSF, NASA, JPL, Dudley Observatory, the Fund for Astrophysical Research, Research Corporation, the University of Illinois at Urbana-Champaign, and Swarthmore College.

    2001-12-01

    We present a statistical study of the electric field scattered from a three-dimensional penetrable object buried under a two-dimensional random rough surface. Monte Carlo simulations using the steepest-descent fast multipole method (SDFMM) are conducted to calculate the average and the standard deviation of the near-zone scattered fields. The SDFMM, originally developed at the University of Illinois at Urbana-Champaign, has been modified to calculate the unknown surface currents both on the rough ground and on the buried object that are due to excitation by a tapered Gaussian beam. The rough ground medium used is an experimentally measured typical dry Bosnian soil with 3.8% moisture, while the buried object represents a plastic land mine modeled as an oblate spheroid with dimensions and burial depth smaller than the free-space wavelength. Both vertical and horizontal polarizations for the incident waves are studied. The numerical results show that the TNT mine signature is almost 5% of the total field scattered from the ground. Moreover, relatively recognizable object signatures are observed even when the object is buried under the tail of the incident beam. Interestingly, even for the small surface roughness parameters considered, the standard deviation of the object signature is almost 30% of the signal itself, indicating significant clutter distortion that is due to the roughness of the ground.

  10. Magnetomotive optical coherence tomography for elastography of small biosamples

    2008-10-01

    Optical coherence tomography (OCT) is a 3D micron-resolution imaging modality using the low-coherence properties of near-infrared light to render depth-resolved images typically a few millimeters into biological tissue. Visco-elasticity is an important parameter for detecting and staging various human diseases. We report a method for analyzing the visco-elastic properties of small tissue samples using magnetomotive OCT. Superparamagnetic nanoparticles (MNPs, ˜20nm) are diffused into a tissue sample. Subsequently, an electromagnet is modulated with a chirped frequency waveform from 0-1kHz, providing a modulated force on the MNPs in the tissue. The mechanical response of the tissue is recorded using OCT at linerates of 1-10kHz. Because OCT is a coherence imaging technique, sub-wavelength displacements are detected in the phase of the interferogram. The mechanical frequency response and associated phase lag fit a model for a damped harmonic oscillator, and results in homogeneous agarose cylinders can be interpreted in terms of Love's solutions for longitudinal vibration modes. A rat mammary tumor biopsy was also analyzed with this technique during formaldehyde fixation, and a trend toward higher frequency correlates with stiffening of the tissue during the fixation process.

  11. New small quantum dots for neuroscience

    NASA Astrophysics Data System (ADS)

    Selvin, Paul

    2014-03-01

    In "New Small Quantum Dots for Neuroscience," Paul Selvin (University of Illinois, Urbana-Champaign) notes how the details of synapsis activity in the brain involves chemical receptors that facilitate the creation of the electrical connection between two nerves. In order to understand the details of this neuroscience phenomenon you need to be able to "see" what is happening at the scale of these receptors, which is around 10 nanometers. This is smaller than the diffraction limit of normal microscopy and it takes place on a 3 dimensional structure. Selvin describes the development of small quantum dots (on the order of 6-9 microns) that are surface-sensitized to interact with the receptors. This allows the application of photo-activated localized microscopy (PALM), a superresolution microscopy that can be scanned through focus to develop a 3D map on a scale that is the same size as the emitter, which in this case are the small quantum dots. The quantum dots are stable in time and provide access to the receptors which allows the imaging of the interactions taking place at the synoptic level.

    I work to build systems that make environmental data more accessible and usable for others—a role that I love and, ten years ago, would not have guessed I would play. I transitioned from conducting pure research to learning more about data curation and information science, and eventually, to combining knowledge of both the research and data science worlds in my current position at the U.S. Geological Survey Center for Integrated Data Analytics (USGS CIDA). At the USGS, I primarily work on the Water Quality Portal, an interagency tool for providing high performance, standards driven access to water quality data, and the USGS Publications Warehouse, which plays a key and ever expanding role in providing access to USGS Publications and their associated data sets. Both projects require an overarching focus on building services to make science data more visible and accessible to users. In addition, listening to the needs of the research scientists who are both collecting and using the data to improve the tools I guide the development of. Concepts that I learned at the University Of Illinois at Urbana-Champaign Graduate School of Library and Information Science Data Curation Education Program were critical to a successful transition from the research world to the data science world. Data curation and data science are playing an ever-larger role in surmounting current and future data challenges at the USGS, and the need for people with interests in both research and data science will continue to grow.

    We consider the p + n + n system using the Argonne v18 plus the Urbana IX three-nucleon potential in the adiabatic hyperspherical description. Considering the J = 1 / 2 + state, we solve for bound states and scattering properties in a two-step method. First, we use a hyperspherical harmonic expansion to calculate the adiabatic potential curves as a function of the hyperradius R. Second, we solve the remaining set of coupled equations in R using Gauss-Lobatto basis function in a discrete variable representation together with a slow variable discretization of R [O. I. Tolstikhin, S. Watanabe, and M. Matsuzawa, J. Phys. B 29 L389 (1996)]. The resulting bound state energies not only agree well with benchmark calculations, but also show favorable convergence properties in comparison with the direct calculation of the coupling matrices. Two- and three-body scattering properties of the system are also calculated and extension to other scattering states and to the four-nucleon problem are discussed. This work is supported in part by funding from the NSF.

    Identification by the Rosetta mission that CH_3NCO is among the more plentiful molecules on the surface of the comet Churyumov-Gerasimenko stimulated rapid detection of this molecule in the interstellar medium. In particular, we have been successful in detecting almost 400 lines of CH_3NCO in Orion^b by extending the Koput cm-wave assignment to frequencies relevant to mm-wave radio-telescopes through measurement of the complete laboratory spectrum up to 363 GHz. Presently, we describe further progress in understanding the laboratory rotational spectrum of CH_3NCO. Assignment has been extended to transitions with K>3 by analysis of Stark and hyperfine patterns of the corresponding lowest-J transitions. Broadband spectra of synthezised pure 13CH_3NCO and CH_3N13CO isotopic species have also been recorded and assigned. Furthermore, the progress in fitting this very low barrier and highly perturbed internal rotation spectrum is described.

  15. Assessing cultural validity in standardized tests in stem education

    NASA Astrophysics Data System (ADS)

    Gassant, Lunes

    This quantitative ex post facto study examined how race and gender, as elements of culture, influence the development of common misconceptions among STEM students. Primary data came from a standardized test: the Digital Logic Concept Inventory (DLCI) developed by Drs. Geoffrey L. Herman, Michael C. Louis, and Craig Zilles from the University of Illinois at Urbana-Champaign. The sample consisted of a cohort of 82 STEM students recruited from three universities in Northern Louisiana. Microsoft Excel and the Statistical Package for the Social Sciences (SPSS) were used for data computation. Two key concepts, several sub concepts, and 19 misconceptions were tested through 11 items in the DLCI. Statistical analyses based on both the Classical Test Theory (Spearman, 1904) and the Item Response Theory (Lord, 1952) yielded similar results: some misconceptions in the DLCI can reliably be predicted by the Race or the Gender of the test taker. The research is significant because it has shown that some misconceptions in a STEM discipline attracted students with similar ethnic backgrounds differently; thus, leading to the existence of some cultural bias in the standardized test. Therefore the study encourages further research in cultural validity in standardized tests. With culturally valid tests, it will be possible to increase the effectiveness of targeted teaching and learning strategies for STEM students from diverse ethnic backgrounds. To some extent, this dissertation has contributed to understanding, better, the gap between high enrollment rates and low graduation rates among African American students and also among other minority students in STEM disciplines.

    Drinking water distribution systems (DWDSs) harbor the microorganisms in biofilms and suspended communities, yet the diversity and spatiotemporal distribution have been studied mainly in the suspended communities. This study examined the diversity of biofilms in an urban DWDS, its relationship with suspended communities and its dynamics. The studied DWDS in Urbana, Illinois received conventionally treated and disinfected water sourced from the groundwater. Over a 2-year span, biomass were sampled from household water meters (n=213) and tap water (n=20) to represent biofilm and suspended communities, respectively. A positive correlation between operational taxonomic unit (OTU) abundance and occupancy was observed. Examined under a ‘core-satellite' model, the biofilm community comprised 31 core populations that encompassed 76.7% of total 16 S rRNA gene pyrosequences. The biofilm communities shared with the suspended community highly abundant and prevalent OTUs, which related to methano-/methylotrophs (i.e., Methylophilaceae and Methylococcaceae) and aerobic heterotrophs (Sphingomonadaceae and Comamonadaceae), yet differed by specific core populations and lower diversity and evenness. Multivariate tests indicated seasonality as the main contributor to community structure variation. This pattern was resilient to annual change and correlated to the cyclic fluctuations of core populations. The findings of a distinctive biofilm community assemblage and methano-/methyltrophic primary production provide critical insights for developing more targeted water quality monitoring programs and treatment strategies for groundwater-sourced drinking water systems.

    Ion channels are part of nature's solution for regulating biological environments. Every ion channel consists of a chain of amino acids carrying a strong and sharply varying permanent charge, folded in such a way that it creates a nanoscopic aqueous pore spanning the otherwise mostly impermeable membranes of biological cells. These naturally occurring proteins are particularly interesting to device engineers seeking to understand how such nanoscale systems realize device-like functions. Availability of high-resolution structural information from X-ray crystallography, as well as large-scale computational resources, makes it possible to conduct realistic ion channel simulations. In general, a hierarchy of simulation methodologies is needed to study different aspects of a biological system like ion channels. Biology Monte Carlo (BioMOCA), a three-dimensional coarse-grained particle ion channel simulator, offers a powerful and general approach to study ion channel permeation. BioMOCA is based on the Boltzmann Transport Monte Carlo (BTMC) and Particle-Particle-Particle-Mesh (P3M) methodologies developed at the University of Illinois at Urbana-Champaign. In this paper we briefly discuss the various approaches to simulating ion flow in channel systems that are currently being pursued by the biophysics and engineering communities, and present the effect of having anisotropic dielectric constants on ion flow through a number of nanopores with different effective diameters.

    The Habanero software was developed by the National Center for Superconducting Applications at the University of Illinois, Urbana-Champaign, as a framework for the collaborative sharing of Java applications. The Habanero tool performs distributed communication of single-user, computer software interactions to a multiuser collaborative environment. An investigation was conducted to evaluate the capabilities of the Habanero tool in providing an Internet-based collaborative framework for researchers located at different sites and operating on different workstations. These collaborative sessions focused on the sharing of test data and analysis results from materials engineering areas (i.e., fracture mechanics and structural integrity evaluations) related to reactor pressure vessel safety research sponsored by the US Nuclear Regulatory Commission. This report defines collaborative-system requirements for engineering applications and provides an overview of collaborative systems within the project. The installation, application, and detailed evaluation of the performance of the Habanero collaborative tool are compared to those of another commercially available collaborative product. Recommendations are given for future work in collaborative communications.

    The overall goal of this “Integrated Research Training Program of Excellence in Radiochemistry” is to provide a rich and deep research experience in state-of-the-art radiochemistry and in the fundamentals of radioisotopic labeling and tracer methodology to develop researchers who are capable of meeting the challenges of designing and preparing radiotracers of broad applicability for monitoring and imaging diverse biological systems and environmental processes. This program was based in the Departments of Radiology and Radiation Oncology at Washington University Medical School and the Department of Chemistry at the University of Illinois at Urbana Champaign, and it was initially directed by Professor Michael J. Welch as Principal Investigator. After his passing in 2012, the program was led by Professor Suzanne E. Lapi. Programmatic content and participant progress was overseen by an Internal Advisory Committee of senior investigators consisting of the PIs, Professor Mach from the Department of Radiology at Washington University and Professor John A. Katzenellenbogen of the Department of Chemistry at the University of Illinois. A small External Advisory Committee to give overall program guidance was also constituted of experts in radiolabeled compounds and in their applications in environmental and plant science.

    The aim of this study was to model the impact of temperature on the timing of the seasonal shift in relative proportion of Culex restuans Theobald and Culex pipiens L. in Illinois. The temporal pattern of West Nile virus (WNV) and St. Louis encephalitis virus transmission in the midwest exhibits a late summer to early fall peak in activity, which parallels the temporal increase in the abundance of Cx. pipiens. The daily number of egg rafts oviposited by each species has been monitored at multiple surveillance sites in Urbana-Champaign in central Illinois for more than 13 years. The time when the two Culex species are in equal abundance (crossover) varies considerably from year to year. Our investigation of several thermal measures indicated that this variation was related in large part to climatic conditions with warmer (cooler) temperatures correlated to earlier (later) crossover dates. Models based on degree days and the number of days in which the daily maximum temperature exceeded an upper temperature threshold explained more than 60% of the variance in crossover dates. In contrast, models based on the number of days in which the daily minimum temperature exceeded a lower temperature threshold explained no more than 52% of the variance. An evaluation of these models demonstrated that they provide relatively simple and accurate estimates of crossover date from daily temperature data, a necessary component for developing an overall climatic index for the risk of WNV transmission in Illinois.

    The chemical oxygen-iodine laser (COIL) is a high power, fiber deliverable tool, which can be used for a number of different industrial applications. COIL is of particular interest because of its short fiber deliverable wavelength, high scaleable continuous wave power, and excellent material interaction properties. In past research the University of Illinois at Urbana-Champaign identified and decommissioning and decontamination (DD) of nuclear facilities as a primary focus for COIL technology. DD will be a major challenge in the coming decades. The use of a robotically driven fiber delivered cutting/ablation tool in contaminated areas promises to lower risks to workers for the DD mission. Further, the high cutting speed of COIL will significantly reduce the time required to cut contaminated equipment, reducing costs. The high power of COIL will permit the dismantling of thick stacks of piping and equipment as well as reactor vessels. COIL is very promising for the removal of material from contaminated surfaces, perhaps to depths thicker than an inch. Laser cutting and ablation minimizes dust and fumes, which reduces the required number of high efficiency particulate accumulator filters, thus reducing costly waste disposal. Other potential industrial applications for COIL are shipbuilding, automotive manufacturing, heavy machinery manufacturing, tasks requiring underwater cutting or welding, and there appear to be very promising applications for high powers lasers in the oil industry.

    Crop fertilization contributes to more than 40% of total anthropogenic emissions of ammonia (NH3) in Illinois. NH3 released into the atmospheric environment reacts readily with acidic compounds to form small diameter (<2.5μm) particulate matter (PM2.5) resulting in human health effects and deposition to surfaces causing eutrophication. Such emissions are not well characterized, and improved measurements are needed to further validate air quality models. This study seeks to provide improved understanding of the emission pathway of agricultural NH3 by measuring bi-directional flux of gaseous NH3 in an intensively managed agroecosystem. A relaxed eddy accumulation (REA) system was deployed above a maize canopy at the University of Illinois at Urbana-Champaign (UIUC) Energy Biosciences Institute (EBI) Energy Farm. Average NH3 flux was measured throughout the growing season in four-hour periods during the morning and afternoon. The REA coefficient (β) was monitored for the duration of the season. The highest atmospheric NH3 concentration (8.11 μg/m3) was observed during the period nearest fertilization, with a mean concentration of 4.02 μg/m3 ± 2.15 μg/m3. Generally, larger upward fluxes of gaseous NH3 coincided with higher atmospheric NH3 concentration, but large variations were observed during the season. Observed NH3 flux ranged from -0.20 µg /m2s to 0.97 µg/m2s, where negative flux indicates deposition.

  5. Dilemmas of talking about lifestyle changes among couples coping with a cardiac event.

    Persons who have experienced a myocardial infarction (MI) and/or coronary artery bypass graft (CABG) surgery may benefit from a low-fat diet, regular exercise, smoking cessation, and stress management. Yet many patients do not make these changes. A spouse or partner's attempts at support may facilitate or interfere with patient behavior change. The present study explores dilemmas that may arise when couples talk about lifestyle changes following one person's MI or CABG. In interviews carried out in Urbana-Champaign, Illinois, and surrounding communities with 25 patients and 16 partners we found communicating support for lifestyle change may be interpreted as undesired control or criticism. The caring conveyed by talking may be viewed positively but can also threaten patient autonomy and entrap partners in unwanted expectations and obligations. Finally, lifestyle change conversations may reflect empowered patients collaborating with partners to take control of health but can also serve as potent reminders of loss. These multiple, potentially conflicting meanings give an account for why talking with a partner does not always facilitate patient lifestyle change. Understanding these dilemmas also suggests practical implications for helping patients and partners.

  6. Compact Binary Mergers as Multimessenger Sources of Gravitational Waves

    2015-04-01

    On the centennial anniversary of Einstein's theory of general relativity, we are on the verge of directly detecting one of its most remarkable predictions - gravitational waves (GWs). The inspiral and merger of compact binaries - binaries with black hole, neutron star or white dwarf companions - are among the most promising sources of GWs. Many of these sources are likely to generate observable electromagnetic (EM) and/or neutrino counterparts to the GWs, constituting a major advance in multimessenger astronomy. By way of illustration, we describe recent magnetohydrodynamic simulations in general relativity (GRMHD) that show how black hole-neutron star mergers can launch jets, lending support to the idea that such mergers could be the engines that power short-hard gamma-ray bursts. We also discuss other recent GRMHD simulations that show how an inspiraling, supermassive binary black hole in a galaxy core stirs and accretes magnetized plasma that orbits the holes in a circumbinary disk. This process can generate ``precursor'' and ``aftermath'' EM radiation with respect to the peak GW emission at merger. Computer-generated movies highlighting some of these simulations will be shown.

    Different models for conserved two- and three-body electromagnetic currents are constructed from two- and three-nucleon interactions, using either meson-exchange mechanisms or minimal substitution in the momentum dependence of these interactions. The connection between these two different schemes is elucidated. A number of low-energy electronuclear observables, including (i) np radiative capture at thermal neutron energies and deuteron photodisintegration at low energies, (ii) nd and pd radiative capture reactions, and (iii) isoscalar and isovector magnetic form factors of {sup 3}H and {sup 3}He, are calculated in order to make a comparative study of these models for the current operator. The realistic Argonne v{sub 18} two-nucleon and Urbana IX or Tucson-Melbourne three-nucleon interactions are taken as a case study. For A=3 processes, the bound and continuum wave functions, both below and above deuteron breakup threshold, are obtained with the correlated hyperspherical-harmonics method. Three-body currents give small but significant contributions to some of the polarization observables in the {sup 2}H(p,{gamma}){sup 3}He process and the {sup 2}H(n,{gamma}){sup 3}H cross section at thermal neutron energies. It is shown that the use of a current which did not exactly satisfy current conservation with the two- and three-nucleon interactions in the Hamiltonian was responsible for some of the discrepancies reported in previous studies between the experimental and theoretical polarization observables in pd radiative capture.

  9. The Singular Quest for a Universal Tree of Life

    2013-01-01

    Carl Woese developed a unique research program, based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea. In so doing, he and his colleagues at the University of Illinois in Urbana revolutionized microbiology and brought the classification of microbes into an evolutionary framework. Woese also provided definitive evidence for the role of symbiosis in the evolution of the eukaryotic cell while underscoring the importance of lateral gene transfer in microbial evolution. Woese and colleagues' proposal of three fundamental domains of life was brought forward in direct conflict with the prokaryote-eukaryote dichotomy. Together with several colleagues and associates, he brought together diverse evidence to support the rRNA evidence for the fundamentally tripartite nature of life. This paper aims to provide insight into his accomplishments, how he achieved them, and his place in the history of biology. PMID:24296570

    The views that students hold about cultural diversity and its teaching have been investigated to a limited extent in the UK and North America. The objective of this study was to establish whether there is a difference in attitudes between UK and US medical students with regard to this issue. A questionnaire survey was carried out on 191 year one medical students at the University of Illinois (Chicago and Urbana campuses) and University of Leicester. Differences of attitudes between students from the two countries and also between the same ethnic groups across the two countries were compared. There were statistically significant differences between UK and US students in each of the key areas of the balance between different cultures, attitudes of doctors and their practice relating to cultural diversity, culture and its associations with race/skin colour, perspectives on specific cultures and attitudes towards diversity teaching. There were some similarities in how students define culture but differences in how they understand multiculturalism. These findings suggest that programmes need to be tailored to particular circumstances, and that complex models of diversity need to be utilized in order for students to engage with them in a substantive way.

    2007-04-15

    Effective field theory (EFT) is the unique, model independent and systematic low-energy version of QCD for processes involving momenta below the pion mass. A low-energy photonuclear observable in three-body systems, photon polarization parameter at thermal neutron energies is calculated by using pionless EFT up to next-to-next to leading order (N{sup 2}LO). In order to make a comparative study of this model, we compared our results for photon polarization parameter with the realistic Argonne v{sub 18} two-nucleon and Urbana IX or Tucson-Melbourne three-nucleon interactions. Three-body currents give small but significant contributions to some of the observables in the neutron-deuteron radiative capture cross section at thermal neutron energies. In this formalism the three-nucleon forces are needed up to N{sup 2}LO for cut-off independent results. Our result converges order by order in low energy expansion and also cut-off independent at this order.

  12. Dynamic Load Balancing Strategies for Parallel Reacting Flow Simulations

    Pisciuneri, Patrick; Meneses, Esteban; Givi, Peyman

    2014-11-01

    Load balancing in parallel computing aims at distributing the work as evenly as possible among the processors. This is a critical issue in the performance of parallel, time accurate, flow simulators. The constraint of time accuracy requires that all processes must be finished with their calculation for a given time step before any process can begin calculation of the next time step. Thus, an irregularly balanced compute load will result in idle time for many processes for each iteration and thus increased walltimes for calculations. Two existing, dynamic load balancing approaches are applied to the simplified case of a partially stirred reactor for methane combustion. The first is Zoltan, a parallel partitioning, load balancing, and data management library developed at the Sandia National Laboratories. The second is Charm++, which is its own machine independent parallel programming system developed at the University of Illinois at Urbana-Champaign. The performance of these two approaches is compared, and the prospects for their application to full 3D, reacting flow solvers is assessed.

I recall at some length, the work with my Ph.D. mentor, David Bohm, and my postdoctoral mentor, John Bardeen, on electron interaction in metals during the period 1948-55 that helped pave the way for BCS, describe the immediate impact of BCS on a small segment of the Princeton physics community in the early spring of 1957, and discuss the extent to which the Bardeen-Pines-Frohlich effective electron-electron interaction provided a criterion for superconductivity in the periodic system. I describe my lectures on BCS at Niels Bohr's Institute of Theoretical Physics in June 1957 that led to the proposal of nuclear superfluidity, discuss nuclear and cosmic superfluids briefly, and close with a tribute to John Bardeen, whose birth centennial we celebrated in 2008, and who was my mentor, close colleague, and dear friend.

The Center is organized around the construction of "Knowledge Engine for Genomics" (KnowEnG), an E-science framework for genomics where biomedical scientists will have access to powerful methods of data mining, network mining, and machine learning to extract knowledge out of genomics data. The scientist will come to KnowEnG with their own data sets in the form of spreadsheets and ask KnowEnG to analyze those data sets in the light of a massive knowledge base of community data sets called the "Knowledge Network" that will be at the heart of the system. The Center is undertaking discovery projects aimed at testing the utility of KnowEnG for transforming big data to knowledge. These projects span a broad range of biological enquiry, from pharmacogenomics (in collaboration with Mayo Clinic) to transcriptomics of human behavior.

  17. Partial-reflection studies of D-region winter variability. [electron density measurements

    D-region electron densities were measured from December, 1972, to July, 1973, at Urbana, Illinois (latitude 40.2N) using the partial-reflection technique. During the winter, electron densities at altitudes of 72, 76.5, and 81 km show cyclical changes with a period of about 5 days that are highly correlated between these altitudes, suggesting that the mechanism responsible for the winter anomaly in D-region ionization applies throughout this height region. From January 13 to February 3, a pronounced wave-like variation occurred in the partial-reflection measurements, apparently associated with a major stratospheric warming that developed in that period. During the same time period, a traveling periodic variation is observed in the 10-mb height; it is highly correlated with the partial-reflection measurements. Electron density enhancements occur approximately at the same time as increases in the 10-mb height. Comparison of AL and A3 absorption measurements with electron density measurements below 82 km indicates that the winter anomaly in D-region ionization is divided into two types. Type 1, above about 82 km, extends horizontally for about 200 km while type 2, below about 82 km, extends for a horizontal scale of at least 1000 km.

    Several proposals for the realization of Majorana fermions rely on excellent quality proximity coupling between a superconductor and a high-mobility semiconductor. We examine the long-range proximity coupling between MBE-grown InAs and in situ grown superconducting overlayers by fabricating transport devices, and investigate the effect of substrate choice and growth conditions on the quality of the MBE InAs. GaAs is commonly available as a high quality insulating substrate. Overcoming its lattice mismatch with InAs using GaSb and AlSb layers results in locally smooth terraced surfaces, but global spiral dislocation structures also appear and have a negative impact on the InAs mobility. Growing InAs on homoepitaxial GaSb results in improved morphology and increases the mean free path. We compare the proximity effect in devices made both ways. This material is based upon work supported by the U.S. Department of Energy, Division of Materials Sciences under Award No. DE-FG02 07ER46453, through the Frederick Seitz Materials Research Laboratory at the University of Illinois at Urbana-Champaign.

    2009-12-01

    Recent large-scale laboratory experiments on the formation of ripples under oscillatory flow are presented. The experiments were performed in the Large Oscillatory Water-Sediment Tunnel (LOWST) at University of Illinois at Urbana-Champaign, using 250 μm silica sand as sediment. The dimensions of the ripples formed under a wide range of flow conditions are compared with some of the existing predictors and with a new predictor presented in a companion paper. For a given near-bed water excursion the size of the ripples is observed to initially decrease with the increase of the maximum orbital velocity, as has been suggested before. However, an abrupt change of the ripple size and the transition to large round-crested ripples is observed when the maximum orbital velocity becomes larger than 0.5 m/s. Above this value the size of these round-crested ripples continuously increased with the increase of the maximum orbital velocity. Additionally, anorbital ripples were never formed despite the long water excursions used in several of our experiments, confirming that anorbital ripples are only formed in fine sands. Finally, the performance of the existing planform geometry predictors and a newly proposed predictor is evaluated using our new experimental data. The results confirm that the bed planform geometry is controlled by the wave Reynolds number and the particle size. The comparison or the new data with previous results from narrow facilities shows that the facility width can restrict the development of bed form three-dimensionality.

    Goal is to assess technical and economic feasibility for producing fertilizer-grade ammonium sulfate from gypsum produced in limestone flue gas desulfurization (FGD). This is the 1st year of a 2-year program among Illinois State Geological Survey, University of Illinois (Urbana-Champaign), Allied-Signal, Marketing Chem. Process Inc., Henry Fertilizer, Illinois Power Co., and Central Illinois Public Services. In previous quarter, chemistry and process conditions were reviewed and a reactor system set up and used to conduct laboratory tests. FGD-gypsum from Abbott power plant was used. The scrubber, a Chiyoda Thoroughbred 121 FGD, produced a filter cake (98.36% gypsum and < 0.01% CaSO{sub 3}). Conversion of FGD- gypsum to ammonium sulfate was tested at 60-70{degree}C for 5-6 hr. Yield up to 82% and purity up to 95% were achieved for the ammonium sulfate production. During this quarter, more bench-scale experiments including a mass balance analysis were conducted; a yield up to 83% and up to 99% purity were achieved. A literature survey was completed and a preliminary process flow sheet was developed. Economics of the process is being estimated.

    Mergers of neutron star-neutron star (NSNS) binaries are among the most promising candidates for the engines that power short gamma-ray bursts (sGRBs). The most likely sGRB model requires the presence of a highly relativistic jet. However, recent relativistic simulations of NSNS mergers have shown that it is difficult for such jets to emerge following the delayed collapse of the hypermassive neutron star (HMNS) remnant. Varying the initial NS magnetic field in an NSNS binary, we have performed magnetohydrodynamic simulations in full general relativity that explore the formation of jets from the black hole-disk system following the HMNS collapse. In this talk we focus on initial dipole magnetic fields confined to the neutron star interior.

Dr. Anthony Mezzacappa is the Principal Investigator on the Illinois award. A separate award was issued to Santa Clara University to continue the collaboration during the time period May 2003 ? 2004. Smolarski continued to work on preconditioner technology and its interface with various iterative methods. He worked primarily with F. Dough Swesty (SUNY-Stony Brook) in continuing software development started in the 2002-03 academic year. Special attention was paid to the development and testing of difference sparse approximate inverse preconditioners and their use in the solution of linear systems arising from radiation transport equations. The target was a high performance platform on which efficient implementation is a critical component of the overall effort. Smolarski also focused on the integration of the adaptive iterative algorithm, Chebycode, developed by Tom Manteuffel and Steve Ashby and adapted by Ryan Szypowski for parallel platforms, into the radiation transport code being developed at SUNY-Stony Brook.

    Since 2002, researchers at the University of Illinois, Urbana-Champaign, Illinois, have been studying the perennial warm-season grass Miscanthus × giganteus (M. × g.) to determine its potential as a biomass feedstock. M. × g. originated in Japan and is a hybrid believed to have M. sinensis and M. sacchariflorus as its parents. Until recently, it was used as a landscape plant in the United States, but it is now the subject of research interest because of its potentially great biomass production. In central Illinois, M. × g. begins growth in April, typically reaches 2 m by the end of May, and is normally greater than 3 m by the end of September. The grass is sterile and propagated asexually using plantlets produced in tissue culture or by rhizome divisions. Following field planting, it generally takes at least three growing seasons to become fully established and reach optimal biomass production. In central Illinois, the senesced stems are harvested from early December through early March and can potentially be treated to produce ligno-cellulosic ethanol. In University of Illinois, research started in 2002. M. × g. produced an annual average of 22.0 t/ha in northern Illinois, 34.7 t/ha in central Illinois, and 35.4 t/ha in southern Illinois per year in 2004, 2005, and 2006.

    In this paper we report on the thermospheric winds and temperatures over Oukaimeden Observatory in Morocco in some stormy nights during the year 2014. These results are based on Fabry-Perot interferometer (FPI) measurements of Doppler shifts and Doppler broadenings of the 630.0nm spectral emission and pertain to the lower thermosphere region, near 250km altitude. This FPI is a part of RENOIR experiment installed thanks to scientific cooperation program with university of Illinois Urbana (USA).The storm energy input modify the global circulation in the thermosphere resulting in significant changes in the ionospheric plasma properties. Thermospheric and ionospheric storms are closely connected.We first set up the climatological behavior of the thermospheric winds and temperature during quiet nights. These results will be presented in this session in a separate abstract (M. Kaab & Z. Benkhaldoun et al) . Then we investigate the departure of the winds and the temperatures from their climatological behavior during some magnetic storms. The winds present many features. We can notice westward winds and an enhancement of the equatorward winds with sometimes an appearance of a poleward component. We also notice a significant increase of the temperature that last several hours. By looking trough the geomagnetic indices we investigate the delay of thermospheric storm time in our region and its effects on the winds and temperature patterns.

  5. Characterization of self-healing composite materials

    NASA Astrophysics Data System (ADS)

    Ford, Kevin John

    Damage occurs in almost every composite material in the form of microcracks that develop in the epoxy matrix that binds the fibers together. Researchers at the University of Illinois Urbana Champaign have recently developed a method to reverse the effects of, or heal, damage in the epoxy matrix. Their in-situ self-healing system uses embedded microcapsules and a catalyst that trigger a romp reaction in an effort to rebond the microcracks. Several models have been developed in an effort to predict how a composite laminate damages. One model in particular, the Continuous Damage Mechanics model, CDM that has been developed at West Virginia University uses material properties that are easily obtained from standard ASTM and ISO testing methods. The CDM model has been extended at West Virginia University to incorporate the effects of a self-healing system to develop a Continuous Damage and Healing Mechanics model, CDHM. In this work, a testing procedure to characterize the autonomic healing of polymer matrix composites is outlined, as well as the regenerative effects of the self-healing system. The capability of the CDHM model to predict the material properties of the self-healing system is also addressed. The CDHM model is validated with experimental results for various laminates fabricated out of E-glass/epoxy.

    We have recently demonstrated the integration of cavity-enhanced direct frequency comb spectroscopy with buffer gas cooling to acquire high resolution infrared spectra of translationally and rotationally cold (˜10 K) gas-phase molecules. Here, we extend this method to significantly larger systems, including naphthalene (C10H_8), a prototypical polyaromatic hydrocarbon, and adamantane (C10H_{16}), the fundamental building block of diamonoids. To the authors' knowledge, the latter molecule represents the largest system for which rotationally resolved spectra in the CH stretch region (3 μm) have been obtained. In addition to the measured spectra, we present several details of our experimental methods. These include introducing non-volatile species into the cold buffer gas cell and obtaining broadband spectra with single comb mode resolution. We also discuss recent modifications to the apparatus to improve its absorption sensitivity and time resolution, which facilitate the study of both larger molecular systems and cold chemical dynamics.

    This report summarizes our research activities at the University of Virginia conducted under the support of this NASA research grant from March 2004 to October 2004 and provides a summary of the research to be conducted in the remaining period of the project at the University of Illinois at Urbana-Champaign (UIUC). The original research objectives will remain the same after our transition to UIUC. In the beginning of this program we completed the analysis on the graphite polymer micro and nanocomposites that were studied at NASA Langley and UVa in the summer of 2003. A publication summarizing this work was submitted in the fall of 2004 to the journal of Experimental Mechanics and the reviewer comments are currently addressed. The research program aims at understanding the local interactions between the polymer matrix and hard reinforcement in polymer nanocomposites (PNCs). The materials selected for this study were PNCs with different fillers (14nm silica nanospheres or nanoclays) and volume fractions (0.5%, 1%, 2% and 5%).

    This project funded the C4 and CAM (crassulacean acid metabolism) Plant Biology 2013 symposium, held at the University of Illinois at Urbana-Champaign, IL, on August 6-9, 2013. The symposium brought together a diverse group of scientists to discuss the evolution, ecology, functional biology, genomics and biotechnological engineering of C4 and CAM plants. These two groups of plants possess evolutionary modifications to their photosynthetic machinery that improve their performance in hot and dry conditions. Maize and pineapple are classic examples of C4 and CAM plants, respectively. The meeting discussed how lessons learned from these groups of plants can be harnessed to improve crop production of biofuel feedstocks in an era of global climate change. The interdisciplinary nature of the meeting meant that the delegation members typically do not collectively attend any one scientific society meeting. As a result, the symposium was a unique opportunity for knowledge transfer, initiation of new collaborations, and recruitment and exposure of early career scientists.

  12. Nuclear and neutron matter studies

    1995-08-01

    We are studying nuclear and neutron matter with the new Argonne v{sub 18} NN and Urbana 3N potentials. We use variational wave functions and a diagrammatic cluster expansion with Fermi hypernetted and single-operator chain (FHNC/SOC) integral equations to evaluate the energy expectation value. Initial results show some interesting differences with our previous calculations with the older Argonne v{sub 14} potential. In particular, there are a number of diagrams involving L{center_dot}S and L{sup 2} terms which were small with the older model and were rather crudely estimated or even neglected. It appears that these terms are more important with the new potential and will have to be evaluated more accurately. Work on this subject is in progress. A simple line of attack is to just add additional diagrams at the three-body cluster level. A longer term approach may be to adapt some of the methods for evaluating nucleon clusters used in the few-body and closed shell nuclei described above.

    During the early morning of October 31, 1988 two large sporadic Na (Na{sub s}) layers were observed near the mesopause above Urbana, IL (40{degree}N, 88{degree}W) with a Na lidar system. The layers began forming near 102 km at 0026 LST and 0110 LST and moved downward with vertical velocities as high as 4 ms{sup {minus}1} before dissipating between 94 and 96 km. The duration of each layer was approximately 80 min. The layers were narrow ({approximately} 1 km FWHM) and dense with maximum densities approaching 7,800 cm{sup {minus}3}. The characteristics of these two Na{sub s} layers are very similar to those of similar phenomena observed recently at Andoya, Norway and Mauna Kea, Hawaii. Lidar observations of the mesospheric Na layer have been conducted routinely by several groups at mid-latitudes for almost 20 years. Although large Na{sub s} layers now appear to be relatively common at low- and high-latitudes, to our knowledge the two layers described in this letter are only the second observation of this puzzling phenomenon at mid-latitudes.

    The HIDRA stellarator (formerly WEGA) at the University of Illinois at Urbana-Champaign has begun operation in partially-ionized conditions. Using the coupled EMC3-EIRENE code the 3D edge plasma region may be self-consistently simulated including the effects of neutrals and impurities. By including Bohm-like cross-field diffusivity into EMC3, valid for classical stellarator designs like HIDRA, a preliminary consideration of expected operating conditions in HIDRA's magnetic geometry may be presented. Axial magnetic field strengths between 87.5 mT and 0.5 T are considered with whole-device power levels scanned from 26 kW to 250 kW. An ITER-sized divertor tile is considered as a limiter positioned around the five-fold symmetry of the device with inboard, outboard, and `trench' poloidal orientations. Divertor-relevant materials including carbon, lithium, and molybdenum have been simulated. Particle and energy confinement times, impurity and neutral energy sinks, and resulting particle and heat fluxes incident on potential limiter geometries are presented.

    1988-05-01

    Results are presented from measurements of the effects of inclement weather on the fluctuations in amplitude and phase of millimeter-wave (MMW) signals propagated through the atmosphere. These measurements were made at frequencies near 116, 140, 173, and 230 GHz at a site near Champaign-Urbana, Illinois, in a community chosen for its exceptional flatness and lack of terrain features that might perturb the atmosphere. It was found that this inclement weather fluctuations are generally smaller than those observed in clear air under sunny conditions, and are also smaller than the corresponding effects observed at visible and near-infrared wavelengths. Typical values of the intensity standard deviation observed (in 20-s intervals) were 1 percent in rain, 0.2 percent in fog, and 1.5-2.5 percent in snow. Typical values of the standard deviation of wavefront angle-of-arrival were 40, 5, 4, and 1 microrad from clear air, snow, rain, and fog, respectively. It was also found that rain has the greatest effect on MMW transmission, causing large, slow changes in received signal strength as a function of rain rate. It should also be noted that rain caused the only observed loss of the propagation link, during a thunderstorm in which the rain rate was as high as 60 mm/h. It is concluded that, in general, millimeter-wave radiation propagates well in adverse weather, with rain causing the major problems observed during this series of measurements.

    We present results of numerical simulations of deformation of a confined droplet in a three-dimensional square-duct flow using a multiphase Lattice Boltzmann Method. We have studied the effects of capillary number, Reynolds number, and viscosity ratio on the droplet deformation characteristics. Unlike in the Stokes' limit where deformation is governed by a competition between viscous shear and interfacial tension, at higher Reynolds numbers, inertial effects play an increasingly important role. We observe that the deformation history is non-monotonic and contains an overshoot before relaxing to a steady deformed state. In contrast, the capillary number is seen to affect the magnitude of the deformation history and the time at which the peak deformation occurs. The viscosity ratio has a relatively modest effect on the magnitude of the deformation compared with the effects of Reynolds and capillary numbers. However, compared with the Reynolds number, the viscosity ratio and capillary number have a significant effect on the time to reach a steady state.

    The research of the Energy Research Group (ERG) at the University of Illinois at Urbana-Champaign through the 1970s and early 1980s has recurring bouts of popularity. That research traced the flow of various energy types from nature to the final product or service, using modified economic input-output analysis. That information allowed for a comparison of alternative uses of products and services that delivered the same demand. The goal of the study was to identify the energy-conserving potential of the alternatives. Interest in that research has risen and fallen with the price of energy through three cycles now, with the current interest also encompassing materials conservation. Although the specific numerical results of this work are dated, the process by which the analysis was conducted creates, at least, a suggestion for future analysis in the arena of materials research. A review of the ERG history, including techniques pioneered for investigating the potential for energy conservation and some of the ancillary lessons learned along the way, may be of some use to those working on issues of materials conservation today. In the coming years, the most relevant research will include assessment of the socio-economic-ecological impact of technological materials conservation policies.

  18. Valuing preferences over stormwater management outcomes including improved hydrologic function

    Stormwater runoff causes environmental problems such as flooding, soil erosion, and water pollution. Conventional stormwater management has focused primarily on flood reduction, while a new generation of decentralized stormwater solutions yields ancillary benefits such as healthier aquatic habitat, improved surface water quality, and increased water table recharge. Previous research has estimated values for flood reduction from stormwater management, but no estimates exist for the willingness to pay (WTP) for some of the other environmental benefits of alternative approaches to stormwater control. This paper uses a choice experiment survey of households in Champaign-Urbana, Illinois, to estimate the values of several attributes of stormwater management outcomes. We analyzed data from 131 surveyed households in randomly selected neighborhoods. We find that people value reduced basement flooding more than reductions in yard or street flooding, but WTP for basement flood reduction in the area only exists if individuals are currently experiencing significant flooding themselves. Citizens value both improved water quality and improved hydrologic function and aquatic habitat from runoff reduction. Thus, widespread investment in low impact development stormwater solutions could have very large total benefits, and stormwater managers should be wary of policies and infrastructure plans that reduce flooding at the expense of water quality and aquatic habitat.

The MMC unites the four DOE BES electron microscopy user facilities at ANL, LBNL, ORNL, and the CMM at the University of Illinois at Urbana-Champaign. Also participating in the MMC are the DOE EE microcharacterization user center at ORNL and the NAMT program at NIST. MMC also has several industrial partners. The purpose of the MMC is to bring the microanalytical and microcharacterization tools and expertise at these centers of excellence and other participating facilities together in an on-line interactive collaboratory and make them available to educators and researchers working in industry, universities, and government laboratories through telepresence access and operation. The MMC, however, is about remote collaboration, not just remote instrument control. The approach of the MMC also emphasizes providing the tools for establishing a sense of community and performing research using the MMC. The CMM has several instruments and peripherals available on-line emphasizing a Web-centric approach with varying levels of access and functionality. This program has developed and implemented hardware and software tools for remote and collaborative operation.

  20. The levels of bilirubin may be related to an inflammatory condition in patients with coronary heart disease.

    In agreement with previous reports, we found that the bilirubin level is significantly lower in the blood of patients with coronary heart disease (CHD) than in age and sex matched controls. However, we found that the level of bilirubin in the blood seemed to be an age-dependent phenomenon and closely related to the activation of leukocytes. In 1,000 cardiac catheterised patients from Urbana, USA suffering from CHD, the level of blood bilirubin was found to be lower than in age and sex-matched controls. The same results were obtained on 300 patients with acute ischemia from three hospitals from Bucharest, Romania. The activation of polymorphonuclear leukocytes increased in the catheterised patients, as well in Romanian patients. An activation of leukocytes triggered by a chronic inflammatory process may increase the lysis of erythrocytes. The erythrocytes of patients with 100% stenosis exhibited a higher rate of in vitro lysis in the presence of activated leukocytes and homocysteine. The increased hemolysis may trigger the activation and removal of the resulting bilirubin from blood. Such a mechanism may depend on the liver clearing function. This function was decreased in catheterized patients over 60 years of age, but had accelerated in younger patients. An individual variation in liver function may explain the widespread bilirubin levels in the blood of patients suffering from CHD.

  1. Variational Study of the Supernova Equation of State with Hyperons

    NASA Astrophysics Data System (ADS)

    Togashi, Hajime; Hiyama, Emiko; Takano, Masatoshi

    We report on a new equation of state (EOS) of nuclear matter containing Λ hyperons constructed with the variational many-body theory for core-collapse supernova simulations. Bare baryon interactions, including the Argonne v18 two-nucleon and Urbana IX three-nucleon potentials are adopted, and the energy per baryon at zero temperature is calculated with the cluster variational method. The free energy per baryon at finite temperature is calculated with an extension of the variational method proposed by Schmidt and Pandharipande. The resulting thermodynamic quantities of hyperonic nuclear matter for various densities, temperatures, and proton fractions under the equilibrium condition μ n = μ Λ are reasonable as compared with those of the Shen EOS. It is also observed that the fraction of Λ hyperons in hot dense matter increases as the proton fraction decreases or the temperature increases. Furthermore, due to the smaller symmetry energy with our EOS, the Λ fraction of our EOS for neutron-rich matter is less than that of the Shen EOS.

  2. World-Wide Experience with SRF Facilities

    2011-03-01

    The speaker will review and analyze the performance of existing SRF facilities in the world, addressing issues of usage and availability for different customers (HEP research, material sciences, ADS). Lessons learned should be summarized for proposed future facilities (ILC, Project X, Muon Collider). The first use of superconducting cavities for accelerating beams was at HEPL, Stanford University in the early sixties. Rather quickly, other laboratories followed suit, notably the University of Illinois at Champagne, Urbana and Cornell University. There were two main uses, which still persist today. The first is to provide accelerated particles as an injector or for fixed target experiments. The second is to maintain circulating beams, either for synchrotron light sources or for colliding beam experiments. Given the differing requirements, these two uses led to rather different implementations and, in particular, different average operating gradients. A second difference in the implementation is the speed of the particle being accelerated. Electrons are sufficiently relativistic at low beam energies (> {approx} 5 MeV) that cavities designed for relativistic beams can also function acceptably at low energy. This is not the case for protons or ion accelerators so, until recently, copper cavities were used to cover the first {approx} 100 MeV. Superconducting cavities are now also being proposed to cover this energy range as well using a series of superconducting cavities, each of which is matched to the particle velocity.

Resumen En este artículo se resume la diversidad de las poblaciones y comunidades microbianas en el subsuelo. A partir de exploraciones realizadas en el subsuelo, los científicos se están cuestionando en la actualidad aspectos relativos a la diversidad microbiana, las interacciones entre los distintos microorganismos y los mecanismos para el mantenimiento de las comunidades de microbios. Se ha comprobado la presencia de comunidades microbianas anaerobias y heterótrofas en areniscas relativamente permeables y en sedimentos arenosos ubicados cerca de depósitos ricos en materia orgánica, de la cual se alimentan. Algunas fuentes de material orgánico, que actúan como donantes de electrones, son: sedimentos del Eoceno ricos en lignito, bajo la planicie costera de Texas; pizarras del Cretácico ricas en materia orgánica, al sudoeste del país y arcillas cretácicas con materia orgánica y bacterias fermentativas, en la llanura Atlántica. También existen comunidades microbianas de gran diversidad en rocas ígneas, aunque la fuente de materia orgánica no es tan evidente. Algunos ejemplos son la subsuperficie del valle del Río Columbia, rico en basaltos, y las regiones graníticas de Suecia y Canadá. Estas comunidades microbianas subsuperficiales se mantienen por la acción de bacterias litotrópicas, que crecen en ambiente de H2, generado en la subsuperficie. También existen comunidades microbianas a gran profundidad

Through the speeches of ACS, it describes how the community perceives the person in psychic suffering and how it positions itself in the face of your everyday problems, as regards the rejection, prejudice, discrimination ne loss of identity. However it is emphasized that, because of being inserted in the community, the community health worker realizes more accurate way in which this social group is the person in mental distress. The rejection of the person who became ill is seen as a fairly common reaction, accompanied by prejudice and discrimination, marginalizing her from society.

  6. Downstream of downtown: urban wastewater as groundwater recharge

    NASA Astrophysics Data System (ADS)

    Foster, S. S. D.; Chilton, P. J.

    Wastewater infiltration is often a major component of overall recharge to aquifers around urban areas, especially in more arid climates. Despite this, such recharge still represents only an incidental (or even accidental) byproduct of various current practices of sewage effluent handling and wastewater reuse. This topic is reviewed through reference to certain areas of detailed field research, with pragmatic approaches being identified to reduce the groundwater pollution hazard of these practices whilst attempting to retain their groundwater resource benefit. Since urban sewage effluent is probably the only `natural resource' whose global availability is steadily increasing, the socioeconomic importance of this topic for rapidly developing urban centres in the more arid parts of Asia, Africa, Latin America and the Middle East will be apparent. L'infiltration des eaux usées est souvent la composante essentielle de toute la recharge des aquifères des zones urbaines, particulièrement sous les climats les plus arides. Malgré cela, une telle recharge ne constitue encore qu'un sous-produit incident, ou même accidentel, de pratiques courantes variées du traitement de rejets d'égouts et de réutilisation d'eaux usées. Ce sujet est passé en revue en se référant à certaines régions étudiées en détail, par des approches pragmatiques reconnues pour permettre de réduire les risques de pollution des nappes dues à ces pratiques tout en permettant d'en tirer profit pour leur ressource en eau souterraine. Puisque les effluents d'égouts urbains sont probablement la seule « ressource naturelle » dont la disponibilité globale va croissant constamment, l'importance socio-économique de ce sujet est évidente pour les centres urbains à développement rapide de l'Asie, de l'Afrique, de l'Amérique latine et du Moyen-Orient. La infiltración de aguas residuales es a menudo un componente principal de la recarga total en acuíferos ubicados en torno a zonas urbanas

    here increased the pond's TSS (and associated pollution) removal efficiency from 46% (current state) to between 70 and 90%, depending on the pond's capacity considered. The RTC strategies allow simultaneously maximizing the detention time of water, while minimizing the hydraulic shocks induced to the receiving water bodies and preventing overflow. A constraint relative to a maximum time of 4 days with water accumulated in the pond was thus respected to avoid mosquito breeding issues. The predictive control schemes (taking rainfall forecasts into consideration) can further reinforce the safety of the management strategies, even if meteorological forecasts are, of course, not error-free. With RTC, the studied pond capacity could thus have been limited to 1250 m3 instead of the 4000 m3 capacity currently used under static control. References Marsalek, J. 2005.

There are very few comparative studies of the differences in hydraulic conditions and morphologic features of bed- and water-surface-waves associated with cyclic steps and antidunes. In this study, the features of both the bed and the water surface, as well as hydraulic conditions are examined over the spectrum from antidune to cyclic steps. Experiments were performed using a flume at the Osaka Institute of Technology. The resultant features of the bedforms are as follows. In the case of antidunes, bed waves and water surface waves are in phase except when they collapse. Antidunes show several kinds of behavior; migrating downstream, standing, or migrating upstream. Upstream-migrating antidunes are divided into non-breaking, and breaking-types. Breaking antidunes appear alternatively with the plane bed state. Cyclic steps migrate upstream regularly associated with trains of hydraulic jumps, which divide each step. There is a significant change in water depth at the hydraulic jump, so that the phasing between the bed waves and water surface waves break at the each hydraulic jump. There is a kind of compromise between cyclic steps and antidunes, which we designate as “intermediate steps”. They move upstream and are associated with regular trains of hydraulic jumps. The jumps, however, occasionally collapse toward upstream. When this happens, bed waves move rapidly upstream; low-amplitude water surface waves and bed waves become in phase all over the bed shortly after the collapse. Then after some time, water surface waves become sufficiently prominent to yield regular hydraulic jumps. This cycle is then repeated

    learning of astronomy in basic education. Embora a astronomia seja considerada uma das ciências mais antigas da humanidade e ainda que a compreensão de seus conceitos tenha trazido enormes avanços para a Ciência e, consequentemente, para a sociedade, observa-se que uma parcela significativa de pessoas encontra-se à margem desses conhecimentos. De acordo com os Parâmetros Curriculares Nacionais para a Educação Básica, cabe à escola a difusão dos conceitos cientificamente corretos, entre eles os relacionados à área de astronomia. Pertinente a essa questão, apresenta-se uma pesquisa realizada com 140 estudantes do nono ano do ensino fundamental e com 120 estudantes da terceira série do ensino médio de quatro escolas da região de Passo Fundo/RS. Buscou-se averiguar, por meio de um questionário composto de questões abertas e de múltipla escolha, o conhecimento desse grupo de estudantes acerca de termos e fenômenos astronômicos básicos e, também, verificar se o índice de acertos cresce à medida que eles avançam nas diferentes e gradativas séries dos ensinos fundamental e médio. De modo geral, os resultados apresentados demonstram que o ensino de astronomia na educação básica enfrenta deficiências. Das 20 questões investigadas, em 17 os índices de acertos são semelhantes nas respostas dadas por estudantes de nível fundamental e médio, revelando que muitas concepções equivocadas permanecem ao longo da educação básica. Isso evidencia que tais temas não são - ou são pouco - abordados durante esses dois níveis de escolarização. Assim, conclui-se que a discussão dos conceitos relacionados com a astronomia deve receber maior ênfase na abordagem dos diferentes conteúdos, sendo necessária uma ação nacional em prol do seu ensino. Acredita-se que essa ação nacional deve estar apoiada em um pilar triplo de atores coletivos: comunidade científica, comunidade astronômica semiprofissional e comunidade escolar.

    The sensitivity of the middle atmospheric temperature and circulation to the treatment of mean- flow forcing due to breaking gravity waves was investigated using the University of Illinois at Urbana-Champaign 40-layer Mesosphere-Stratosphere-Troposphere General Circulation Model (MST-GCM). Three GCM experiments were performed. The gravity-wave forcing was represented first by Rayleigh friction, and then by the Alexander and Dunkerton (AD) parameterization with weak and strong breaking effects of gravity waves. In all experiments, the Palmer et al. parameterization was included to treat the breaking of topographic gravity waves in the troposphere and lower stratosphere. Overall, the experiment with the strong breaking effect simulates best the middle atmospheric temperature and circulation. With Rayleigh friction and the weak breaking effect, a large warm bias of up to 60 C was found in the summer upper mesosphere and lower thermosphere. This warm bias was linked to the inability of the GCM to simulate the reversal of the zonal winds from easterly to westerly crossing the mesopause in the summer hemisphere. With the strong breaking effect, the GCM was able to simulate this reversal, and essentially eliminated the warm bias. This improvement was the result of a much stronger meridional transport circulation that possesses a strong vertical ascending branch in the summer upper mesosphere, and hence large adiabatic cooling. Budget analysis indicates that 'in the middle atmosphere the forces that act to maintain a steady zonal-mean zonal wind are primarily those associated with the meridional transport circulation and breaking gravity waves. Contributions from the interaction of the model-resolved eddies with the mean flow are small. To obtain a transport circulation in the mesosphere of the UIUC MST-GCM that is strong enough to produce the observed cold summer mesopause, gravity-wave forcing larger than 100 m/s/day in magnitude is required near the summer mesopause.

    The astrophysical S factor for the radiative capture d(p,γ)^{3}He in the energy range of interest for big bang nucleosynthesis (BBN) is calculated using an ab initio approach. The nuclear Hamiltonian retains both two- and three-nucleon interactions-the Argonne v_{18} and the Urbana IX, respectively. Both one- and many-body contributions to the nuclear current operator are included. The former retain for the first time, besides the 1/m leading order contribution (m is the nucleon mass), also the next-to-leading order term, proportional to 1/m^{3}. The many-body currents are constructed in order to satisfy the current conservation relation with the adopted Hamiltonian model. The hyperspherical harmonics technique is applied to solve the A=3 bound and scattering states. Particular attention is paid in this second case in order to obtain, in the energy range of BBN, an uncertainty on the astrophysical S factor of the order or below ∼1%. Then, in this energy range, the S factor is found to be ∼10% larger than the currently adopted values. Part of this increase (1%-3%) is due to the 1/m^{3} one-body operator, while the remaining is due to the new more accurate scattering wave functions. We have studied the implication of this new determination for the d(p,γ)^{3}He S factor on the deuterium primordial abundance. We find that the predicted theoretical value for ^{2}H/H is in excellent agreement with its experimental determination, using the most recent determination of the baryon density of the Planck experiment, and with a standard number of relativistic degrees of freedom N_{eff}=3.046 during primordial nucleosynthesis. This calls for a more accurate measurement of the astrophysical S factor in order to confirm the present predictions.

    Background Treatment of overweight and obesity through body weight reduction has been monumentally ineffective as few individuals are able to sustain weight loss. Rather than treating weight gain once it has become problematic, prevention of weight gain over time may be more effective. Objective The aim of this research is to preclude the burden of adult obesity in women by identifying the determinants of weight gain prevention. The objective of this randomized controlled trial (RCT) is to compare a weight gain prevention intervention delivered by the registered dietitian versus counselor. Methods This is a 12-month parallel-arm weight gain prevention RCT designed to increase self-efficacy, self-regulation, outcome expectations and family and social support through the use of a nutrition education intervention in women, aged 18-45 years, from the Urbana-Champaign (Illinois, USA) area. Women have been randomized to registered dietitian, counselor or wait-list control groups (August 2014) and are undergoing weekly nutrition education sessions for four months, followed by monthly sessions for eight months (through August 2015). Outcome measures, including: (1) dietary intake, (2) physical activity, (3) anthropometric and blood pressure measurements, (4) biochemical markers of health, (5) eating behaviors and health perceptions, and (6) mediators of behavior change, were collected before the intervention began (baseline) and will be collected at 3, 6, 9, and 12 months of the study. Results In total, 87 women have been randomized to intervention groups, and 81 women have completed first week of the study. Results are expected in early 2016. Conclusions This RCT is one of the first to examine weight gain prevention in women across normal, overweight, and obese body mass index categories. Results of this research are expected to have application to evidence-based practice in weight gain prevention for women and possibly have implication for policy regarding decreasing the

    The present study identifies a process for performing computational fluid dynamic calculations of the flow over full three-dimensional (3D) representations of complex ice shapes deposited on aircraft surfaces. Rime and glaze icing geometries formed on a NACA23012 airfoil were obtained during testing in the NASA Glenn Research Center's Icing Research Tunnel (IRT). The ice shape geometries were scanned as a cloud of data points using a 3D laser scanner. The data point clouds were meshed using Geomagic software to create highly accurate models of the ice surface. The surface data was imported into Pointwise grid generation software to create the CFD surface and volume grids. It was determined that generating grids in Pointwise for complex 3D icing geometries was possible using various techniques that depended on the ice shape. Computations of the flow fields over these ice shapes were performed using the NASA National Combustion Code (NCC). Results for a rime ice shape for angle of attack conditions ranging from 0 to 10 degrees and for freestream Mach numbers of 0.10 and 0.18 are presented. For validation of the computational results, comparisons were made to test results from rapid-prototype models of the selected ice accretion shapes, obtained from a separate study in a subsonic wind tunnel at the University of Illinois at Urbana-Champaign. The computational and experimental results were compared for values of pressure coefficient and lift. Initial results show fairly good agreement for rime ice accretion simulations across the range of conditions examined. The glaze ice results are promising but require some further examination.

  14. A New Approach to Calculate Indirect GWPs using the UIUC 2-D CRT and RTM Model

    Global warming potentials (GWPs) are defined to be the total impact over time of adding a unit mass of a greenhouse gas to the atmosphere. Indirect GWPs are due to ozone depletion effects in the stratosphere for a certain compound and therefore stand for the long-term global cooling effects. Previously, indirect GWPs were calculated using a box model, which was not able to consider the complex processes in the atmosphere. As a step towards obtaining indirect GWPs through a more robust approach, the UIUC 2-D CRT model was used as the computational tool to derive ozone changes. The 2-D model has more realistic chemical, physical, and dynamical processes in the atmosphere and a relatively complete transport system, which makes it useful for a more accurate analysis. Furthermore, the University of Illinois at Urbana-Champaign (UIUC) radiative transfer model (RTM) is employed to derive the corresponding time-dependent radiative forcings from the 2-D CRT outputs. Two Halon compounds, Halon-1211 and Halon-1301, were selected to be studied for their indirect GWPs. The results showed that instantaneous and stratospheric adjusted indirect GWPs for a 100-year horizon are -10004.8 and -10237.1 for Halon-1211, while for Halon-1301 they are -19218.0 and -19627.6. The indirect GWPs for Halon-1211 and -1301 presented here are two to three times smaller compared to the results in WMO (2006) draft. Further analysis on indirect GWPs will be carried out using our 3-D MOZART-3 model.

    The fate of a 1 kg/ha application of granular chlorine-36-labeled DDT made by helicopter on 10 June 1969 to a 4-ha old-field study area near Urbana, Ohio was traced and quantified in soil and biota through November 1974. Between 1970 and 1974, residues of DDT (DDTR, includes DDT plus metabolites) declined from 22.0 to 3.8 mg/kg tissue in earthworms (Lumbricus terrestris) and from 9.3 to 2.1 mg/kg in slugs (Deroceras laeve). Levels of DDTR in foliage of grasses and forbs increased from 2-3 mg/kg in 1970 to 7.6 mg/kg in 1974, but remained relatively constant at 1.6 mg/kg in roots. Amounts of residues in samples of air collected at the surface of the soil were positively correlated with amounts in soil and with air temperature. The total quantity of DDTR in the top 12 cm of soil was estimated to be 1779 g in October 1974, or 38% of the amount applied in 1969. Earthworms, which comprised the largest component of animal biomass, contained 5% of the total DDTR in the ecosystem in 1969, compared to 3% in the plants and other biota. As residues declined in earthworms and increased in plants over time, the total DDTR bound in the biota increased until it accounted for 22% of the total DDTR in the ecosystem in 1974. Losses of DDTR from the ecosystem each year were attributed primarily to volatilization from soil, because losses in runoff and emigrating insects and small mammals were negligible. 12 references, 7 figures, 6 tables.

    Advances in scientific computing research have never been more vital to the core missions of Lawrence Livermore National Laboratory than they are today. These advances are evolving so rapidly, and over such a broad front of computational science, that to remain on the leading edge, the Laboratory must collaborate with many academic centers of excellence. In FY 1998, ISCR dramatically expanded its interactions with academia through collaborations, visiting faculty, guests and a seminar series. The pages of this annual report summarize the activities of the 63 faculty members and 34 students who participated in ISCR collaborative activities during FY 1998. The 1998 ISCR call for proposals issued by the University Collaborative Research Program (UCRP) resulted in eight awards made by the University of California Office of the President to research teams at UC San Diego, UC Davis, UC Los Angeles, and UC Berkeley. These projects are noted. ISCR is now part of the Laboratory's Center for Applied Scientific Computing (CASC). Many CASC scientists participate actively in ISCR University collaborations, as noted. The eight collaborations shown represent innovative research efforts supported by ISCR in FY 1998. Abstracts discussing each of these collaborations begin on page 79. The Accelerated Strategic Computing Initiative (ASCI) established Academic Strategic Alliances Program (ASAP) centers located at: Stanford University; California Institute of Technology; University of Chicago; University of Utah, Salt Lake; and University of Illinois, Urbana-Champaign. The ASCI Alliances strategy was established to enhance overall ASCI goals by establishing technical interactions between the Department of Energy, Defense Programs laboratories (Lawrence Livermore, Los Alamos, and Sandia National Laboratories), and leading-edge research-and-development universities in the United States. ISCR has partnered with the LLNL ASCI Program Office to facilitate these collaborations. In FY 1998

Glenn Hwy., Dayton, OH 45435, USAbIllinois State Geological Survey, Prairie Research Institute, University of Illinois at Urbana-Champaign, 615 East Peabody Drive, Champaign, IL 61820, USA A number of important candidate CO2 reservoirs exhibit sedimentary architecture reflecting fluvial deposition. Recent studies have led to new conceptual and quantitative models for sedimentary architecture in fluvial deposits over a range of scales that are relevant to CO2 injection and storage, led to new geocellular modelling approaches for representing this architecture, and led to new computational studies of CO2 plume dynamics during and after injection. The processes of CO2 trapping depend upon a complex system of non-linear and hysteretic characteristic relationships including how relative permeability and capillary pressure vary with brine and CO2 saturation. New computational studies of capillary trapping in conglomeratic reservoirs strongly suggest that representing small-scale (decimeter to meter) textural facies among different rock types, including their organization within a hierarchy of larger-scale stratification, representing differences in characteristic relationships between rock types, and representing hysteresis in characteristic curves can all be critical to understanding trapping processes. In this context, CO2trapping was evaluated in conglomeratic reservoirs with fluvial architecture including different rock types with different and hysteretic characteristic curves and with capillary pressure defined for each rock type using two different conventional approaches, i.e. Brooks-Corey and van Genuchten. The results show that in these reservoirs the capillary trapping rates are quite sensitive to differences between the Brooks-Corey and van Genuchten approaches, and that

    A field-scale compacted soil liner was constructed at the University of Illinois at Urbana-Champaign by the U.S. Environmental Protection Agency (USEPA) and Illinois State Geological Survey in 1988 to investigate chemical transport rates through low permeability compacted clay liners (CCLs). Four tracers (bromide and three benzoic acid tracers) were each added to one of four large ring infiltrometers (LRIs) while tritium was added to the pond water (excluding the infiltrometers). Results from the long-term transport of Br- from the localized source zone of LRI are presented in this paper. Core samples were taken radially outward from the center of the Br- LRI and concentration depth profiles were obtained. Transport properties were evaluated using an axially symmetric transport model. Results indicate that (1) transport was diffusion controlled; (2) transport due to advection was negligible and well within the regulatory limits of ksat???1 ?? 10-7 cm/s; (3) diffusion rates in the horizontal and vertical directions were the same; and (4) small positioning errors due to compression during soil sampling did not affect the best fit advection and diffusion values. The best-fit diffusion coefficient for bromide was equal to the molecular diffusion coefficient multiplied by a tortuosity factor of 0.27, which is within 8% of the tortuosity factor (0.25) found in a related study where tritium transport through the same liner was evaluated. This suggests that the governing mechanisms for the transport of tritium and bromide through the CCL were similar. These results are significant because they address transport through a composite liner from a localized source zone which occurs when defects or punctures in the geomembrane of a composite system are present. ??

    We report here a narrowband high-spectral resolution sodium temperature/wind lidar recently developed at the University of Science and Technology of China (USTC) in Hefei, China (31.5 °N, 117 °E). Patterned after the Colorado State University (CSU) narrowband sodium lidar with a dye laser-based transmitter, the USTC sodium temperature/wind lidar was deployed with a number of technical improvements that facilitate automation and ease of operation; these include a home constructed pulsed dye amplifier (PDA), a beam-steering system, a star-tracking program, and an electronic timing control. With the averaged power of ∼1.2 W output from PDA and the receiving telescope diameter of 0.76 m, our lidar system has a power aperture product of ∼0.55 Wm(2) and is comparable to the CSU and the University of Illinois at Urbana-Champaign (UIUC) sodium lidar systems. The uncertainties of typical measurements induced by photon noise and laser locking fluctuation for the temperature and wind with a 2 km vertical and 15 min temporal resolutions under the nighttime clear sky condition are estimated to be ∼1.0 K and ∼1.5 m/s, respectively, at the sodium peak (e.g., 91 km), and 8 K and 10 m/s, respectively, at both sodium layer edges (e.g., 81 km and 105 km). The USTC narrowband sodium lidar has been operated regularly during the night since November 2011. Using the initial data collected, we demonstrate the reliability and suitability of these high resolution and precision datasets for studying the wave perturbations in the mesopause region.

    Background Identifying effective intervention strategies to combat age-related decline in mobility and brain health is a priority. The primary aim of our study was to examine whether 12 months of aerobic training (AT) versus balance and toning (BAT) exercises moderates the relationship between change in mobility and change in basal ganglia volume in older adults. Design Secondary analysis of a randomized controlled trial. Setting Champaign-Urbana, Illinois. Participants Community-dwelling older adults (N = 101; mean age = 66.41 years) Intervention 12-month exercise trial with two groups: AT and BAT. Measurements Mobility was assessed by the Timed Up and Go (TUG) test. Basal ganglia (putamen, caudate nucleus, pallidum) was segmented from T1-weighted MR images using FIRST. Measurements were obtained at baseline and trial completion. Hierarchical multiple regression was conducted to examine whether exercise mode moderates the relationship between change in mobility and change in basal ganglia volume over 12 months. Age, sex, and education were included as covariates. Results Exercise mode significantly moderated the relationship between change in mobility and change in left putamen volume. Specifically, for the AT group, volume of the left putamen did not change, regardless of change in mobility. Similarly, in the BAT group, those who improved their mobility most over 12 months had no change in left putamen volume; however, those who declined in mobility levels significantly decreased in left putamen volume. Conclusion Our primary finding that older adults who engage in 12 months of balance and tone training and improve mobility exhibit maintenance of brain volume in a key region responsible for motor control provides compelling evidence that such exercises can contribute to the promotion of functional independence and healthy aging.
