  8. Combined LAURA-UPS hypersonic solution procedure

    NASA Technical Reports Server (NTRS)

    Wood, William A.; Thompson, Richard A.

    1993-01-01

    A combined solution procedure for hypersonic flowfields around blunted slender bodies was implemented using a thin-layer Navier-Stokes code (LAURA) in the nose region and a parabolized Navier-Stokes code (UPS) on the after body region. Perfect gas, equilibrium air, and non-equilibrium air solutions to sharp cones and a sharp wedge were obtained using UPS alone as a preliminary step. Surface heating rates are presented for two slender bodies with blunted noses, having used LAURA to provide a starting solution to UPS downstream of the sonic line. These are an 8 deg sphere-cone in Mach 5, perfect gas, laminar flow at 0 and 4 deg angles of attack and the Reentry F body at Mach 20, 80,000 ft equilibrium gas conditions for 0 and 0.14 deg angles of attack. The results indicate that this procedure is a timely and accurate method for obtaining aerothermodynamic predictions on slender hypersonic vehicles.

    PubMed

    Basso Lorini, Elisabetta

    2017-02-01

    This paper analyses the historical and epistemological work of the French psychiatrist Georges Lantéri-Laura (1930-2004) within the context of the French 'tradition' of history and philosophy of sciences, with special reference to Georges Canguilhem and Michel Foucault. After an introduction devoted to a critical survey of the most recent works on the history and historiography of psychiatry in French, the paper outlines Lantéri-Laura's approach by focusing especially on the role played by the methodological concept of 'semiology' as regards the relation between medicine and psychiatry. The last part of the paper draws attention to the relation between the history and philosophy of psychiatry in light of Lantéri-Laura's 'critical epistemology'.

  19. Ground-water resources of the Laura area, Majuro Atoll, Marshall Islands

    USGS Publications Warehouse

    Hamlin, S.N.; Anthony, S.S.

    1987-01-01

    The water system that supplies the heavily populated Dalap-Uliga-Darrit (DUD) area of Majuro atoll, Marshall Island, relies almost entirely upon airstrip catchment of rain water. Droughts cause severe water supply problems and water rationing is required, even during periods of normal rainfall. The Laura area contains a substantial lens of fresh groundwater that could be developed for export to the DUD area 30 mi to the east. Study of the groundwater resource at Laura involved a survey of existing wells, installation of monitoring wells and test holes, compilation of continuous records of rainfall and water level fluctuations, and collection of water quality data. Test hole data permitted the definition of three geohydrologic units which correlate well with similar units in Bikini and Enewetak atolls. The units consist of two layers of unconsolidated reef and lagoon sediments resting on a dense, highly permeable limestone. The potable water zone, or freshwater nucleus, of the lens is contained mostly within the unconsolidated layers, which are much less permeable than the basal limestone. Recharge to the Laura freshwater lens is estimated to be 1.8 mil gal/day, based on an average annual rainfall of 140 in. Sustainable yield is estimated to be about 400,000 gal/day. Shallow skimming wells or infiltration galleries similar to those used on Kwajalein atoll would be appropriate to develop the freshwater lens. The impact of development on the lens can be determined by monitoring the salinity in developed water and in a network of monitor wells. (Author 's abstract)

We her family had been with her throughout her traumatic experience. This is our story.

  1. Distributed-Memory Computing With the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA)

    NASA Technical Reports Server (NTRS)

    Riley, Christopher J.; Cheatwood, F. McNeil

    1997-01-01

    The Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA), a Navier-Stokes solver, has been modified for use in a parallel, distributed-memory environment using the Message-Passing Interface (MPI) standard. A standard domain decomposition strategy is used in which the computational domain is divided into subdomains with each subdomain assigned to a processor. Performance is examined on dedicated parallel machines and a network of desktop workstations. The effect of domain decomposition and frequency of boundary updates on performance and convergence is also examined for several realistic configurations and conditions typical of large-scale computational fluid dynamic analysis.

  2. Combined LAURA-UPS solution procedure for chemically-reacting flows. M.S. Thesis

    NASA Technical Reports Server (NTRS)

    Wood, William A.

    1994-01-01

    A new procedure seeks to combine the thin-layer Navier-Stokes solver LAURA with the parabolized Navier-Stokes solver UPS for the aerothermodynamic solution of chemically-reacting air flowfields. The interface protocol is presented and the method is applied to two slender, blunted shapes. Both axisymmetric and three dimensional solutions are included with surface pressure and heat transfer comparisons between the present method and previously published results. The case of Mach 25 flow over an axisymmetric six degree sphere-cone with a noncatalytic wall is considered to 100 nose radii. A stability bound on the marching step size was observed with this case and is attributed to chemistry effects resulting from the noncatalytic wall boundary condition. A second case with Mach 28 flow over a sphere-cone-cylinder-flare configuration is computed at both two and five degree angles of attack with a fully-catalytic wall. Surface pressures are seen to be within five percent with the present method compared to the baseline LAURA solution and heat transfers are within 10 percent. The effect of grid resolution is investigated and the nonequilibrium results are compared with a perfect gas solution, showing that while the surface pressure is relatively unchanged by the inclusion of reacting chemistry the nonequilibrium heating is 25 percent higher. The procedure demonstrates significant, order of magnitude reductions in solution time and required memory for the three dimensional case over an all thin-layer Navier-Stokes solution.

  4. Application of program LAURA to thermochemical nonequilibrium flow through a nozzle

    NASA Technical Reports Server (NTRS)

    Gnoffo, Peter A.

    1991-01-01

    Program LAURA (Langley Aerothermodynamic Upwind Relaxation Algorithm) is an upwind-biased, point-implicit relaxation algorithm for obtaining the numerical solution to the governing equations for 3D viscous hypersonic flows in chemical and thermal nonequilibrium. The algorithm is derived using a finite-volume formulation in which the inviscid components of flux across cell walls are described with a modified Roe's averaging and with second-order corrections based on Yee's Symmetric Total Variation Diminishing scheme. The code has been applied to Problem 8.2 of this workshop for the case of thermochemical nonequilibrium flow through a nozzle. Chemical reaction rates are defined with the model of Park (1987). Thermal nonequilibrium is modeled using a two-temperature approximation in which the vibrational energies of all molecules are assumed to be in equilibrium at a single temperature which is generally different from the translational-rotational temperature. Two grids were used to define the flow for the original problem, with a stagnation temperature of 6500 K. A third case with a stagnation temperature of 10,000 K is also presented. The solution domain includes the converging nozzle, subsonic flow domain in which the gas is substantially in thermochemical equilibrium and the diverging nozzle, hypersonic flow domain in which the gas is substantially in thermochemical nonequilibrium.

  8. Performance of the OVERFLOW-MLP and LAURA-MLP CFD Codes on the NASA Ames 512 CPU Origin System

    NASA Technical Reports Server (NTRS)

    Taft, James R.

    2000-01-01

    The shared memory Multi-Level Parallelism (MLP) technique, developed last year at NASA Ames has been very successful in dramatically improving the performance of important NASA CFD codes. This new and very simple parallel programming technique was first inserted into the OVERFLOW production CFD code in FY 1998. The OVERFLOW-MLP code's parallel performance scaled linearly to 256 CPUs on the NASA Ames 256 CPU Origin 2000 system (steger). Overall performance exceeded 20.1 GFLOP/s, or about 4.5x the performance of a dedicated 16 CPU C90 system. All of this was achieved without any major modification to the original vector based code. The OVERFLOW-MLP code is now in production on the inhouse Origin systems as well as being used offsite at commercial aerospace companies. Partially as a result of this work, NASA Ames has purchased a new 512 CPU Origin 2000 system to further test the limits of parallel performance for NASA codes of interest. This paper presents the performance obtained from the latest optimization efforts on this machine for the LAURA-MLP and OVERFLOW-MLP codes. The Langley Aerothermodynamics Upwind Relaxation Algorithm (LAURA) code is a key simulation tool in the development of the next generation shuttle, interplanetary reentry vehicles, and nearly all "X" plane development. This code sustains about 4-5 GFLOP/s on a dedicated 16 CPU C90. At this rate, expected workloads would require over 100 C90 CPU years of computing over the next few calendar years. It is not feasible to expect that this would be affordable or available to the user community. Dramatic performance gains on cheaper systems are needed. This code is expected to be perhaps the largest consumer of NASA Ames compute cycles per run in the coming year.The OVERFLOW CFD code is extensively used in the government and commercial aerospace communities to evaluate new aircraft designs. It is one of the largest consumers of NASA supercomputing cycles and large simulations of highly resolved full

  9. Effects of the 1998 Drought on the Freshwater Lens in the Laura Area, Majuro Atoll, Republic of the Marshall Islands

    USGS Publications Warehouse

    Presley, Todd K.

    2005-01-01

    Lower than average rainfall during late 1997 and early 1998 in Majuro Atoll, Republic of the Marshall Islands, caused a drought and severe drinking-water shortage. Majuro depends on a public rainfall catchment system, which uses an airport runway and storage reservoirs. The storage reservoirs can supply water for about 30 to 50 days without replenishment. In February 1998, after a few months with less than one inch of rainfall per month, a drought-related disaster was declared. Reverse-osmosis water-purification systems were brought to Majuro to help alleviate the water shortage. Concurrent with the water-purification program, ground water from a freshwater lens in the Laura area of the atoll was pumped at increased rates. Of the total consumed water during this period, ground water from Laura supplied between 90 percent (March 1998) and 64 percent (May 1998) of the drinking water. Due to public concern, a study was initiated to determine the effects of the drought on the freshwater lens. The areal extent of the freshwater lens is about 350 acres. A monitoring-well network, consisting of multiple wells driven to varying depths at 11 sites, was installed to determine the thickness of the freshwater lens. Similar locations relative to an earlier study were chosen so that the data from this study could be compared to 1984-85 data. At the end of the drought in June 1998, the freshwater near the middle of the lens was about 45 feet thick; and at the north and south ends, the freshwater was about 25 to 38 feet thick, respectively. Monitoring of the freshwater lens was continued through the wet season following the drought. The lens increased in thickness by 1 to 8 feet after 7 months of rainfall. Greater increases in lens thickness were measured on the lagoon side than on the ocean side of the freshwater lens. Lens thickness during August 1998, and seasonal variation of lens thickness in 1998, were compared to data collected in 1984-85. Comparison of lens thickness from

  11. Experimenting with wires, batteries, bulbs and the induction coil: Narratives of teaching and learning physics in the electrical investigations of Laura, David, Jamie, myself and the nineteenth century experimenters. Our developments and instruments

    NASA Astrophysics Data System (ADS)

    Cavicchi, Elizabeth Mary

    Physics is conventionally taught as a fixed curriculum which students must master. This thesis changes that: curriculum emerges from what learners try and question in experiments they invent. The thesis narrates: three adult students exploring wires, batteries and bulbs with me as teacher; nineteenth century investigations of electromagnetism; my laboratory work replicating historic instruments. In each case, learning arose through activity with materials. Evidences of this are analyzed within narratives and reflections. I used teaching-research, a method developed by Duckworth from Piaget's clinical interviewing, to research and simultaneously extend students' evolving understandings. What I learned through questioning students informed my next interactions; what they learned extended their experimenting. Similarly, I researched historical accounts interactively: improvising experiments to develop my understandings. Studying my own learning deepened my interpretations of students' learning. My students Laura, David and Jamie experimented by: soldering bulbs to wires, making series and parallel circuits, inserting resistive wire that dimmed bulbs, conducting electricity through salt water They noticed bulb brightness and battery heat, compared electricity's paths, questioned how voltage and current relate. They inferred electricity's effects manifest magnitudes of material properties. They found their experiences while learning were inseparable from what they learned. I researched investigations connected with Cavendish's leather fish, Galvani's frogs, Schweigger's wire spiraled around a compass needle, Henry's electromagnets, Faraday's induction ring, induction devices of Page, Callan, Hearder. Experimentally, I made galvanometers, electromagnets, induction rings, induction coil. I observed effects of electromagnetism, internal resistance, induced sparking. Across these investigations, learning developed with instrumental innovations; confusions were productive

  20. From Laura Ingalls to Wing Biddlebaum: A Survey of Teacher Identities in Works of Literature

    ERIC Educational Resources Information Center

    Muchmore, James A.

    2012-01-01

    Teachers appear as characters in a wide range of literary writing. To date, few scholars have systematically studied the teachers who appear in works of literature. Much of the existing work has focused on relatively small numbers of teachers and has been presented in the form of brief essays rather than formal research (e.g., Booth, 2006; Crume,…

  5. Lercanidipine is an effective and well tolerated antihypertensive drug regardless the cardiovascular risk profile: the LAURA Study

    BARRIOS, V; ESCOBAR, C; NAVARRO, Á; BARRIOS, L; NAVARRO-CID, J; CALDERÓN, A

    2006-01-01

    To determine whether the antihypertensive effectiveness of lercanidipine was independent of the different cardiovascular risk levels. Patients with treated or untreated mild-to-moderate essential hypertension were included in a multicentre, prospective, non-comparative, open-label study. Patients received lercanidipine (10 mg/day, uptitrated to 20 mg/day) during 6 months. A total of 3175 patients, age 63 ± 10 years, 51% women, were included. The cardiovascular risk was low in 237 patients, medium in 1396, high in 722, and very high in 820. At baseline, blood pressure (BP) was 159.5 ± 11.7/95.2 ± 7.4 mmHg. BP was progressively higher according to increase in cardiovascular risk. After 6 months of treatment, BP was 136.0 ± 9.7/79.7 ± 6.8 mmHg. The decrease in systolic BP and diastolic BP at each follow-up visit compared with baseline was statistically significant both in the intergroup and intragroup comparisons (p < 0.001). Mean decreases of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were −18.5/−13.8 mmHg in the low risk group, −23/−15.2 mmHg in the medium risk group, −24.4/−16.1 mmHg in the high risk group, and −27.4/−17.4 mmHg in the very high risk group. Most frequent side effects were oedema (5.1%), headache (3.3%), flushes (2.5%), and asthenia (1%). Only 1.7% of patients discontinued antihypertensive medication because of adverse events. Tolerability of lercanidipine was independent of the cardiovascular risk group. Lercanidipine was effective and well-tolerated in patients with mild-to-moderate hypertension in the daily practice. The effectiveness and safety of the drug were independent of the degree of cardiovascular risk. PMID:17073834

    2016-01-01

    We thank Andrea Tertulliani and his colleagues for their interest in our article on the 2015 Gorkha earthquake (Martin, Hough, et al., 2015), and for their comments pertaining to our study (Tertulliani et al., 2016). Indeed, as they note, a comprehensive assessment of macroseismic effects for an earthquake with far‐reaching effects as that of Gorkha is not only critically important but is also an extremely difficult undertaking. In the absence of a widely known web‐based system, employing a well‐calibrated algorithm with which to collect and systematically assess macroseismic information (e.g., Wald et al., 1999; Coppola et al., 2010; Bossu et al., 2015) in the Indian subcontinent, one is left with two approaches to characterize effects of an event such as the Gorkha earthquake: a comprehensive ground‐based survey such as the one undertaken in India following the 2001 Bhuj earthquake (Pande and Kayal, 2003), or an assessment such as Martin, Hough, et al. (2015) akin to other contemporary studies (e.g., Nuttli, 1973; Sieh, 1978; Meltzner and Wald, 1998; Martin and Szeliga, 2010; Ambraseys and Bilham, 2012; Mahajan et al., 2012; Gupta et al., 2013; Singh et al., 2013; Hough and Martin, 2015; Martin and Hough, 2015; Martin, Bradley, et al., 2015; Ribeiro et al., 2015), based primarily upon media reports and other available documentary accounts.

  9. Volatile emissions of scented Alstroemeria genotypes are dominated by terpenes, and a myrcene synthase gene is highly expressed in scented Alstroemeria flowers.

    PubMed

    Aros, Danilo; Gonzalez, Veronica; Allemann, Rudolf K; Müller, Carsten T; Rosati, Carlo; Rogers, Hilary J

    2012-04-01

    Native to South America, Alstroemeria flowers are known for their colourful tepals, and Alstroemeria hybrids are an important cut flower. However, in common with many commercial cut flowers, virtually all the commercial Alstroemeria hybrids are not scented. The cultivar 'Sweet Laura' is one of very few scented commercial Alstroemeria hybrids. Characterization of the volatile emission profile of these cut flowers revealed three major terpene compounds: (E)-caryophyllene, humulene (also known as α-caryophyllene), an ocimene-like compound, and several minor peaks, one of which was identified as myrcene. The profile is completely different from that of the parental scented species A. caryophyllaea. Volatile emission peaked at anthesis in both scented genotypes, coincident in cv. 'Sweet Laura' with the maximal expression of a putative terpene synthase gene AlstroTPS. This gene was preferentially expressed in floral tissues of both cv. 'Sweet Laura' and A. caryophyllaea. Characterization of the AlstroTPS gene structure from cv. 'Sweet Laura' placed it as a member of the class III terpene synthases, and the predicted 567 amino acid sequence placed it into the subfamily TPS-b. The conserved sequences R(28)(R)X(8)W and D(321)DXXD are the putative Mg(2+)-binding sites, and in vitro assay of AlstroTPS expressed in Escherichia coli revealed that the encoded enzyme possesses myrcene synthase activity, consistent with a role for AlstroTPS in scent production in Alstroemeria cv. 'Sweet Laura' flowers.

  10. Aerodynamic Database Development for Mars Smart Lander Vehicle Configurations

    NASA Technical Reports Server (NTRS)

    Bobskill, Glenn J.; Parikh, Paresh C.; Prabhu, Ramadas K.; Tyler, Erik D.

    2002-01-01

    An aerodynamic database has been generated for the Mars Smart Lander Shelf-All configuration using computational fluid dynamics (CFD) simulations. Three different CFD codes, USM3D and FELISA, based on unstructured grid technology and LAURA, an established and validated structured CFD code, were used. As part of this database development, the results for the Mars continuum were validated with experimental data and comparisons made where applicable. The validation of USM3D and LAURA with the Unitary experimental data, the use of intermediate LAURA check analyses, as well as the validation of FELISA with the Mach 6 CF(sub 4) experimental data provided a higher confidence in the ability for CFD to provide aerodynamic data in order to determine the static trim characteristics for longitudinal stability. The analyses of the noncontinuum regime showed the existence of multiple trim angles of attack that can be unstable or stable trim points. This information is needed to design guidance controller throughout the trajectory.

  13. Characteristics of the Shuttle Orbiter Leeside Flow During A Reentry Condition

    NASA Technical Reports Server (NTRS)

    Kleb, William L.; Weilmuenster, K. James

    1992-01-01

    A study of the leeside flow characteristics of the Shuttle Orbiter is presented for a reentry flight condition. The flow is computed using a point-implicit, finite-volume scheme known as the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA). LAURA is a second-order accurate, laminar Navier-Stokes solver, incorporating finite-rate chemistry with a radiative equilibrium wall temperature distribution and finite-rate wall catalysis. The resulting computational solution is analyzed in terms of salient flow features and the surface quantities are compared with flight data.

    2013-01-01

    The functional equivalence of the unstructured grid code FUN3D to the the structured grid code LAURA (Langley Aerothermodynamic Upwind Relaxation Algorithm) is documented for applications of interest to the Entry, Descent, and Landing (EDL) community. Examples from an existing suite of regression tests are used to demonstrate the functional equivalence, encompassing various thermochemical models and vehicle configurations. Algorithm modifications required for the node-based unstructured grid code (FUN3D) to reproduce functionality of the cell-centered structured code (LAURA) are also documented. Challenges associated with computation on tetrahedral grids versus computation on structured-grid derived hexahedral systems are discussed.

  1. Applying the Unified Protocol Transdiagnostic Treatment to Nonsuicidal Self-Injury and Co-Occurring Emotional Disorders: A Case Illustration.

    PubMed

    Bentley, Kate H

    2017-02-21

    This article presents the use of a transdiagnostic, emotion-focused treatment with a young woman with nonsuicidal self-injury (NSSI), social anxiety disorder, and generalized anxiety disorder. The patient also presented with subclinical depressive, posttraumatic stress, and eating disorder symptoms. The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (Barlow et al., 2011), a cognitive-behavioral intervention designed to be applicable across anxiety, depressive, and related disorders with strong emotional components, was used to address the range of Laura's presenting concerns. After 16 individual treatment sessions, Laura experienced significant reductions in NSSI (and urges to engage in NSSI) as well as observable improvements in her self-reported ability to respond more adaptively to intense emotion. She also reported moderate reductions in her anxiety disorder symptoms. This case illustration demonstrates how a short-term, transdiagnostic treatment approach can be flexibly applied to a variety of problems maintained by aversive and avoidant reactions to intense emotion.

  2. Computational Aerothermodynamic Simulation Issues on Unstructured Grids

    NASA Technical Reports Server (NTRS)

    Gnoffo, Peter A.; White, Jeffery A.

    2004-01-01

    The synthesis of physical models for gas chemistry and turbulence from the structured grid codes LAURA and VULCAN into the unstructured grid code FUN3D is described. A directionally Symmetric, Total Variation Diminishing (STVD) algorithm and an entropy fix (eigenvalue limiter) keyed to local cell Reynolds number are introduced to improve solution quality for hypersonic aeroheating applications. A simple grid-adaptation procedure is incorporated within the flow solver. Simulations of flow over an ellipsoid (perfect gas, inviscid), Shuttle Orbiter (viscous, chemical nonequilibrium) and comparisons to the structured grid solvers LAURA (cylinder, Shuttle Orbiter) and VULCAN (flat plate) are presented to show current capabilities. The quality of heating in 3D stagnation regions is very sensitive to algorithm options in general, high aspect ratio tetrahedral elements complicate the simulation of high Reynolds number, viscous flow as compared to locally structured meshes aligned with the flow.

    This paper considers the solution of the bioelectromagnetic inverse problem with particular emphasis on focal compact sources that are likely to arise in epileptic data. Two linear inverse methods are proposed and evaluated in simulations. The first method belongs to the class of distributed inverse solutions, capable of dealing with multiple simultaneously active sources. This solution is based on a Local Auto Regressive Average (LAURA) model. Since no assumption is made about the number of activated sources, this approach can be applied to data with multiple sources. The second method, EPIFOCUS, assumes that there is only a single focal source. However, in contrast to the single dipole model, it allows the source to have a spatial extent beyond a single point and avoids the non-linear optimization process required by dipole fitting. The performance of both methods is evaluated with synthetic data in noisy and noise free conditions. The simulation results demonstrate that LAURA and EPIFOCUS increase the number of sources retrieved with zero dipole localization error and produce lower maximum error and lower average error compared to Minimum Norm, Weighted Minimum Norm and Minimum Laplacian (LORETA). The results show that EPIFOCUS is a robust and powerful tool to localize focal sources. Alternatives to localize data generated by multiple sources are discussed. A companion paper (Lantz et al. 2001, this issue) illustrates the application of LAURA and EPIFOCUS to the analysis of interictal data in epileptic patients.

    Comparisons are made between the LAURA Navier-Stokes code and Viking Lander Capsule hypersonic aerodynamics data from ground and flight measurements. Wind tunnel data are available for a 3.48 percent scale model at Mach 6 and a 2.75 percent scale model at Mach 10.35, both under perfect gas air conditions. Viking Lander 1 aerodynamics flight data also exist from on-board instrumentation for velocities between 2900 and 4400 m/sec (Mach 14 to 23.3). LAURA flowfield solutions are obtained for the geometry as tested or flown, including sting effects at tunnel conditions and finite-rate chemistry effects in flight. Using the flight vehicle center-of-gravity location (trim angle approx. equals -11.1 deg), the computed trim angle at tunnel conditions is within 0.31 degrees of the angle derived from Mach 6 data and 0.13 degrees from the Mach 10.35 trim angle. LAURA Mach 6 trim lift and drag force coefficients are within 2 percent of measured data, and computed trim lift-to-drag ratio is within 4 percent of the data. Computed trim lift and drag force coefficients at Mach 10.35 are within 5 percent and 3 percent, respectively, of wind tunnel data. Computed trim lift-to-drag ratio is within 2 percent of the Mach 10.35 data. Using the nominal density profile and center-of-gravity location, LAURA trim angle at flight conditions is within 0.5 degrees of the total angle measured from on-board instrumentation. LAURA trim lift and drag force coefficients at flight conditions are within 7 and 5 percent, respectively, of the flight data. Computed trim lift-to-drag ratio is within 4 percent of the data. Computed aerodynamics sensitivities to center-of-gravity location, atmospheric density, and grid refinement are generally small. The results will enable a better estimate of aerodynamics uncertainties for future Mars entry vehicles where non-zero angle-of-attack is required.

    Bryant Pharmaceutical's flagship product, a popular arthritis medicine called Seflex, is selling well--but not well enough. With generic versions due on the shelves in a couple of years, the drug company is looking for a dramatic sales increase. No wonder marketing VP Laura Goldenberg feels the pressure. She knows she has to reach more consumers, but in an environment where people bombarded with advertising are using devices such as TiVo to skip ads, her job has suddenly taken on a new intensity. In search of a new, gangbuster campaign, Laura and her ad agency come up with the idea of product placement--not your typical integration of a product into a television or movie script, but a less traditional approach. Their idea is to hire a much-loved, elderly actress to extol the virtues of Seflex on a morning news program. The news segment would be about arthritis, and Seflex would be casually mentioned during the interview. The company would have to pay the actress $1 million, and there are risks: What if it gets out that Bryant is paying her? What if the actress errs and says something about Seflex's side effects? If something goes wrong, Bryant Pharmaceutical's reputation could suffer. Should the company green-light Laura's plan? This fictional case study looks at the pros and cons of traditional product placement and newer, more subtle alternatives to advertising. Commenting on the case are Bob Gamgort, president of Masterfoods USA; Michelle R. Nelson, an assistant professor of journalism and mass communications at the University of Wisconsin, Madison; FTC commissioner Mozelle W. Thompson; and Mike Sheehan, president and CEO of Hill, Holliday, Connors, Cosmopulos.

    We update the list of the bathyal chitons of the genus Leptochiton inhabiting Chilean waters. We report new records of Leptochiton belknapi and L. laurae, the first record of L. sigwartae for the area and the new species L. ibanezi sp. nov. and L. ferreirai sp. nov. With 12 species, including those described herein as new, the highest species richness of Leptochiton is found in Chilean deep waters. Taking into consideration the potential late Paleozoic origin of the genus Leptochiton, we propose that Leptochiton originated in the old Pacific Ocean and migrated to the young Atlantic Ocean. However, the genus has also been considered non-monophyletic.

    The first woman to earn a Professorship at a University in Europe was Laura Maria Caterina Bassi, who earned a professorship in physics at the University of Bologna in 1732. Almost 300 years and three waves of feminism later, in 2016, women typically still only comprise 20% (or less) of the number of full professors in Europe. This opinion article will discuss the experiences of being a female academic today and the factors contributing to the academic gender gap from the perspective of a “young” natural scientist, as well as providing constructive suggestions for strategies to empower women in the academic world.

    I am very much looking forward to visiting you, the family of physicists gathering for your annual APS conference. In different ways, my grandfather Enrico Fermi is a member of both our families. In this sense we are connected and share a common legacy, which I want to explore from the angle of two women inextricably involved with and affected by the Manhattan Project. One from the past and one alive now. These two women, despite a significant temporal and cultural gap share a remarkable number of traits and values. My talk will not offer a particular thesis or finding. Rather it will be about ways of seeing, including questioning unnoticed assumptions and belief systems. My grandmother Laura Fermi, modeled this for me as a youngster. She was at Enrico's side during the Manhattan Project years, yet in the dark about his work. What was it like to live in a climate of intellectually and patriotically charged enthusiasm, with an undercurrent of unspoken dread? Laura, just like most everyone else, discovered the true nature of the effort on the day the atomic bomb was dropped on Hiroshima. After the war and after Enrico's untimely death in 1954, in response to all she had experienced, Laura re-invented herself as an author and visionary, pioneering in both the environmental and handgun control movements. Marian Naranjo lives on the Santa Clara Pueblo near Los Alamos. Her ancestors dwelled on the Pajarito Plateau which encompasses the space where Los Alamos National Labs (LANL) is today. Her people, the Pueblo People have used the area's natural resources for ceremonial and survival for uncountable generations. They say, ``We are this place.'' What is it like to live on land one's families have safely occupied for thousands of years, with an undercurrent of dread at the prospect of toxic waste stream products from LANL? Like my grandmother did in her place and time, Marian builds community as an integral part of her environmental and social justice activism. She is

    Lunar and Mars return conditions are examined using the LAURA flowfield code and the LORAN radiation code to assess the effect of radiative coupling on axisymmetric thermochemical nonequilibrium flows. Coupling of the two codes is achieved iteratively. Special treatment required to couple radiation in a shock-capturing method is discussed. Results indicate that while coupling effects are generally the same as occur in equilibrium flows, under certain conditions radiation can modify the chemical kinetics of a nonequilibrium flow and thus alter relaxation processes. Coupling effects are found to be small for all cases considered, except for a five meter diameter aerobrake returning from Mars at 13.6 km/sec.

  10. The attitudes and beliefs of a female science teacher: Implications in relation to gender and pedagogical practice

    NASA Astrophysics Data System (ADS)

    Zapata, Mara

    In this case study of a female science teacher named Laura, numerous observations, field notes, researcher interpretations, and assertions were developed. As meanings were negotiated, intent of actions was defined using significant statements, clustered to produce invariant meaning units. Both the participant's intents and how she interpreted her experiences were central to the understandings sought in this study. Whenever Laura planned for teaching science, taught, or otherwise interacted with students, the following four themes seemed to frame her actions: (1) Responsibility to Nurture/Mother/Mentor (2) Connecting to and Relating (3) Meeting Gender-Specific Expectations (4) Promoting the Fighter/Survivor Within. Each theme is examined in relation to attitudes and beliefs about teaching and learning science, and conclusions and assertions are expressed. The findings of this study point to the tensions between Laura's attitudes and beliefs and her pedagogical practices, disconfirming these as they pertain to gender in relation to teaching and learning science. It was not evident as part of her daily practice that student experiences were used in an attempt to create connections between their lives and science, although Laura always emphasized that science is a way of life. The findings support questioning the role of intentionality and a teacher's perceived ability to adhere to intentions while practicing within the norms established by the social institution of schools operating within the larger structures of society. The major findings and implications are relevant to the manner teachers are prepared and encouraged to enact their practice by departments and boards of education, prepared by institutions of higher education and subsequent participation in professional development. Specifically, calling attention to how these educational frameworks emphasize or de-emphasize the role of teachers and promote cognizance in terms of the culture of schools, reflective

    Several current challenges in computational fluid dynamics and aerothermodynamics for hypersonic vehicle applications are discussed. Example simulations are presented from code validation and code benchmarking efforts to illustrate capabilities and limitations. Opportunities to advance the state-of-art in algorithms, grid generation and adaptation, and code validation are identified. Highlights of diverse efforts to address these challenges are then discussed. One such effort to re-engineer and synthesize the existing analysis capability in LAURA, VULCAN, and FUN3D will provide context for these discussions. The critical (and evolving) role of agile software engineering practice in the capability enhancement process is also noted.

Aerothermal environments at flight conditions were evaluated using Langley Aerothermal Upwind Relaxation Algorithm (LAURA) code and Data Parallel Line Relaxation (DPLR) algorithm code. Results show a marked augmentation of aftbody heating due to roll, yaw and aft pitch thrusters. No significant augmentation is expected due to forward pitch thrusters. Of the conditions surveyed the maximum heat rate on the aftshell is expected when firing a pair of roll thrusters at a maximum deceleration condition.

    2003-01-01

    Measurements and predictions of the X-33 turbulent aeroheating environment have been performed at Mach 6, perfect-gas air conditions. The purpose of this investigation was to compare measured turbulent aeroheating levels on smooth models, models with discrete trips, and models with arrays of bowed panels (which simulate bowed thermal protections system tiles) with each other and with predictions from two Navier-Stokes codes, LAURA and GASP. The wind tunnel testing was conducted at free stream Reynolds numbers based on length of 1.8 x 10(exp 6) to 6.1 x 10(exp 6) on 0.0132 scale X-33 models at a = 40-deg. Turbulent flow was produced by the discrete trips and by the bowed panels at ill but the lowest Reynolds number, but turbulent flow on the smooth model was produced only at the highest Reynolds number. Turbulent aeroheating levels on each of the three model types were measured using global phosphor thermography and were found to agree to within .he estimated uncertainty (plus or minus 15%) of the experiment. Computations were performed at the wind tunnel free stream conditions using both codes. Turbulent aeroheating levels predicted using the LAURA code were generally 5%-10% lower than those from GASP, although both sets of predictions fell within the experimental accuracy of the wind tunnel data.

    This glasshouse study used an improved larval measurement procedure to evaluate the impact of transgenic pea, Pisum sativum L., seeds expressing a-amylase inhibitor (AI)-1 or -2 proteins on pea weevil, Bruchus pisorum L. Seeds of transgenic 'Laura' and 'Greenfeast' peas expressing alpha-(AI)-1 reduced pea weevil survival by 93-98%. Larval mortality occurred at an early instar. Conversely, in nontransgenic cultivars, approximately 98-99% of the pea weevils emerged as adults. By measuring the head capsule size, we determined that larvae died at the first to early third instar in alpha-(AI)-1 transgenic peas, indicating that this inhibitor is highly effective in controlling this insect. By contrast, transgenic Laura and 'Dundale' expressing alpha-(AI)-2 did not affect pea weevil survival, but they did delay larval development. After 77 d of development, the head capsule size indicated that the larvae were still at the third instar stage in transgenic alpha-(AI)-2 peas, whereas adult bruchids had developed in the nontransgenic peas.

  3. Grid generation and flow computation about a Martian entry vehicle

    NASA Technical Reports Server (NTRS)

    Stewart, J. E.; Tiwari, S. N.

    1990-01-01

    A number of vehicles are currently being proposed for a manned mission to Mars. One of these vehicles has a modified blunt-nosed cone configuration. Experimental results were obtained for this vehicle in 1968. They show lift-over-drag ratios comparable to those needed for Mars entry. Computations are performed to verify the earlier results and to further describe the flight characteristics of this vehicle. An analytical method is used to define the surface of this vehicle. A single-block volume grid is generated around the vehicle using the algebraic Two-Boundary Grid Generation algorithm (TBGG) and transfinite interpolation. Euler solutions are then obtained from a Langley Aerodynamic Upward Relaxation Algorithm (LAURA) at Mach 6.0 and angles of attack of 0, 6, and 12 deg. The lift coefficient determined from the LAURA code agree very well with the experimental results. The drag and pitching moment coefficients, however, are underestimated by the code since viscous effects are not considered. Contour plots of the flowfield show no evidence of separation for angles of attack up to 12 deg.

    Ongoing work involves several areas of density functional theory: new methods for computing electronic excitation energies, including a new way to remove spin contamination in the spin-flip Tamm-Dancoff approximation and a configuration-interaction-corrected Tamm-Dancoff Approximation for treating conical intersections; new ways to treat open-shell states, including a reinterpreted broken-symmetry method and multi-configuration Kohn-Sham theory; a new exchange-correlation functional; new tests of density functional theory against databases for electronic transition energies and molecules and solids containing metal atoms; and applications. A selection of results will be presented.

    The computational science community is reluctant to write large-scale computationally -intensive applications in Java due to concerns over Java's poor performance, despite the claimed software engineering advantages of its object-oriented features. Naive Java implementations of numerical algorithms can perform poorly compared to corresponding Fortran or C implementations. To achieve high performance, Java applications must be designed with good performance as a primary goal. This paper presents the object-oriented design and implementation of two real-world applications from the field of Computational Fluid Dynamics (CFD): a finite-volume fluid flow solver (LAURA, from NASA Langley Research Center), and an unstructured mesh adaptation algorithm (2D_TAG, from NASA Ames Research Center). This work builds on our previous experience with the design of high-performance numerical libraries in Java. We examine the performance of the applications using the currently available Java infrastructure and show that the Java version of the flow solver LAURA performs almost within a factor of 2 of the original procedural version. Our Java version of the mesh adaptation algorithm 2D_TAG performs within a factor of 1.5 of its original procedural version on certain platforms. Our results demonstrate that object-oriented software design principles are not necessarily inimical to high performance.

  6. Dual-Code Solution Strategy for Chemically-Reacting Hypersonic Flows

    1995-01-01

    A new procedure seeks to combine the thin-layer Navier-Stokes solver LAURA with the parabolized Navier-Stokes solver UPS for the aerothermodynamic solution of chemically-reacting air flow fields. The interface protocol is presented and the method is applied to two slender, blunted shapes. Both axisymmetric and three-dimensional solutions are included with surface pressure and heat transfer comparisons between the present method and previously published results. The case of Mach 25 flow over an axisymmetric six degree sphere-cone with a non-catalytic wall is considered to 100 nose radii. A stability bound on the marching step size was observed with this case and is attributed to chemistry effects resulting from the non-catalytic wall boundary condition. A second case with Mach 28 flow over a sphere-cone-cylinder-flare configuration is computed at both two and five degree angles of attack with a fully-catalytic wall. Surface pressures are seen to be within five percent with the present method compared to the baseline LAURA solution and heat transfers are within 10 percent. The effect of grid resolution is investigated in both the radial and streamwise directions. The procedure demonstrates significant, order of magnitude reductions in solution time and required memory for the three-dimensional case in comparison to an all thin-layer Navier-Stokes solution.

  7. Conservation equations and physical models for hypersonic air flows over the aeroassist flight experiment vehicle

    1989-01-01

    The code development and application program for the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA), with emphasis directed toward support of the Aeroassist Flight Experiment (AFE) in the near term and Aeroassisted Space Transfer Vehicle (ASTV) design in the long term is reviewed. LAURA is an upwind-biased, point-implicit relaxation algorithm for obtaining the numerical solution to the governing equations for 3-D, viscous, hypersonic flows in chemical and thermal nonequilibrium. The algorithm is derived using a finite volume formulation in which the inviscid components of flux across cell walls are described with Roe's averaging and Harten's entropy fix with second-order corrections based on Yee's Symmetric Total Variation Diminishing scheme. Because of the point-implicit relaxation strategy, the algorithm remains stable at large Courant numbers without the necessity of solving large, block tri-diagonal systems. A single relaxation step depends only on information from nearest neighbors. Predictions for pressure distributions, surface heating, and aerodynamic coefficients compare well with experimental data for Mach 10 flow over an AFE wind tunnel model. Predictions for the hypersonic flow of air in chemical and thermal nonequilibrium over the full scale AFE configuration obtained on a multi-domain grid are discussed.

  8. The Influence of Ablation on Radiative Heating for Earth Entry

    Johnston, Christopher O.; Gnoffo, Peter A.; Sutton, Kenneth

    2008-01-01

    Using the coupled ablation and radiation capability recently included in the LAURA flowfield solver, this paper investigates the influence of ablation on the shock-layer radiative heating for Earth entry. The extension of the HARA radiation model, which provides the radiation predictions in LAURA, to treat a gas consisting of the elements C, H, O, and N is discussed. It is shown that the absorption coefficient of air is increased with the introduction of the C and H elements. A simplified shock layer model is studied to show the impact of temperature, as well as the abundance of C and H, on the net absorption or emission from an ablation contaminated boundary layer. It is found that the ablation species reduce the radiative flux in the vacuum ultraviolet, through increased absorption, for all temperatures. However, in the infrared region of the spectrum, the ablation species increase the radiative flux, through strong emission, for temperatures above 3,000 K. Thus, depending on the temperature and abundance of ablation species, the contaminated boundary layer may either provide a net increase or decrease in the radiative flux reaching the wall. To assess the validity of the coupled ablation and radiation LAURA analysis, a previously analyzed Mars-return case (15.24 km/s), which contains significant ablation and radiation coupling, is studied. Exceptional agreement with previous viscous shock-layer results is obtained. A 40% decrease in the radiative flux is predicted for ablation rates equal to 20% of the free-stream mass flux. The Apollo 4 peak-heating case (10.24 km/s) is also studied. For ablation rates up to 3.4% of the free-stream mass flux, the radiative heating is reduced by up to 19%, while the convective heating is reduced by up to 87%. Good agreement with the Apollo 4 radiometer data is obtained by considering absorption in the radiometer cavity. For both the Mars return and the Apollo 4 cases, coupled radiation alone is found to reduce the radiative

    1998-01-01

    Detailed aeroheating information is critical to the successful design of a thermal protection system (TPS) for an aerospace vehicle. This report describes NASA Langley Research Center's (LaRC) two-color relative-intensity phosphor thermography method and the IHEAT software package which is used for the efficient data reduction and analysis of the phosphor image data. Development of theory is provided for a new weighted two-color relative-intensity fluorescence theory for quantitatively determining surface temperatures on hypersonic wind tunnel models; an improved application of the one-dimensional conduction theory for use in determining global heating mappings; and extrapolation of wind tunnel data to flight surface temperatures. The phosphor methodology at LaRC is presented including descriptions of phosphor model fabrication, test facilities and phosphor video acquisition systems. A discussion of the calibration procedures, data reduction and data analysis is given. Estimates of the total uncertainties (with a 95% confidence level) associated with the phosphor technique are shown to be approximately 8 to 10 percent in the Langley's 31-Inch Mach 10 Tunnel and 7 to 10 percent in the 20-Inch Mach 6 Tunnel. A comparison with thin-film measurements using two-inch radius hemispheres shows the phosphor data to be within 7 percent of thin-film measurements and to agree even better with predictions via a LATCH computational fluid dynamics solution (CFD). Good agreement between phosphor data and LAURA CFD computations on the forebody of a vertical takeoff/vertical lander configuration at four angles of attack is also shown. In addition, a comparison is given between Mach 6 phosphor data and laminar and turbulent solutions generated using the LAURA, GASP and LATCH CFD codes. Finally, the extrapolation method developed in this report is applied to the X-34 configuration with good agreement between the phosphor extrapolation and LAURA flight surface temperature predictions

    The majority of the Austral basin fields discovered are mainly associated with structural and combination traps. Except for El Condor, La Sara, and San Sebastian fields, most of the oil reserves of limited size. This is due to several factors: small areal extent (5--50 sq km), variability of the Springhill thickness which frequently wedges out over the top of structures, facies changes and related complex reservoir distributions, and lack of hydrocarbons. Until 1985, all the commercial discoveries have been made in the area of the platform mostly in the Springhill reservoir and to a lesser extent on top of the volcanic Bahia Laura group (equivalent Lemaire or Tobifera formations). However, the Tertiary discoveries in Campo Boleadoras and Puesto Peter fields opened a zone, named Intermediate'' by YPF's geologists, located to the west of the known producing areas. In this zone, the lower member of the Magallanes group has yielded production. Reservoir characteristics are discussed.

    Turbulent CFD simulations are compared against surface temperature measurements of the space shuttle orbiter windward tiles at reentry flight conditions. Algebraic turbulence models are used within both the LAURA and DPLR CFD codes. The flight data are from temperature measurements obtained by seven thermocouples during the STS-128 mission (September 2009). The flight data indicate boundary layer transition onset over the Mach number range 13.5{15.5, depending upon the location on the vehicle. But the boundary layer flow appeared to be transitional down through Mach 12, based upon the flight data and CFD trends. At Mach 9 the simulations match the flight data on average within 20 F/11 C, where typical surface temperatures were approximately 1600 F/870 C.

    Greendyke, Robert B.; Hartung, Lin C.

    1993-01-01

    A Navier-Stokes flowfield solution method (LAURA code) using finite-rate chemistry and two-temperature thermal nonequilibrium was used in combination with two nonequilibrium radiative heat transfer codes to calculate heating for the FIRE II vehicle. An axisymmetric model of the actual body shape was used. One radiative heating code (NEQAIR) was used in uncoupled fashion with the flowfield solver's energy equations, while the other code (LORAN) was used in both coupled and uncoupled variations. Several trajectory points ranging from highly nonequilibrium flow to near-equilibrium flow were used for a study of both convective and radiative heating over the vehicle. Considerable variation in radiative heating was seen at the extremes, while agreement was good in the intermediate trajectory points. Total heat transfer calculations gave good comparison until the peak heating trajectory points were encountered, and returned to good agreement for the last two equilibrium points.

    Nitric-oxide planar laser-induced fluorescence (NO PLIF) was used to visualize and measure centerline streamwise velocity of the Orion Crew Exploration Vehicle (CEV) Reaction Control System (RCS) Jets at NASA Langley Research Center's 31-Inch Mach 10 Air wind tunnel. Fluorescence flow visualizations of pitch, roll, and yaw RCS jets were obtained using different plenum pressures and wind tunnel operating stagnation pressures. For two yaw RCS jet test cases, the PLIF visualizations were compared to computational flow imaging (CFI) images based on Langley Aerothermal Upwind Relaxation Algorithm (LAURA) computational fluid dynamics (CFD) simulations of the flowfield. For the same test cases, the streamwise velocity measurements were compared to CFD. The CFD solution, while showing some unphysical artifacts, generally agree with the experimental measurements.

    1993-01-01

    A Gauss-Seidel implicit aerothermodynamic Navier-Stokes computational CFD code with thermochemical surface conditions (GIANTS) and with appropriate boundary conditions was developed for the analysis of hypersonic arcjet flows over large angle blunt bodies. Two-dimensional axisymmetric multicomponent full Navier-Stokes equations were solved, together with boundary conditions, to account for the surface slip, surface catalysis, and energy and mass conservation at the body surface. It is shown that the predictions for isothermal, noncatalytic, and no-slip surface conditions which are made using the GIANTS code with simple boundary conditions agree with those of the LAURA code, and the predicted normalized heating distributions over the forebody surface with boundary conditions for various cone angles are consistent with the trends of data from arcjet experiments.

    Tomatoes (Lycopersicon esculentum cv. Laura) were separated, according to the ripening stage, by a sensory panel into seven groups, and color was measured on the tomato surface with a Minolta Chroma meter. The L, a, b, hue, chroma, and lycopene content were plotted against the maturity stages of the tomatoes, and several good correlations were found. The a/b ratio and the lycopene content were the parameters that allowed six of seven maturity groups in the tomato to be statistically distinguished. The lycopene content, measured by HPLC, was also correlated with the color measurements, and the a, a/b, and (a/b)(2) color factors produced the best regressions. An estimation of the lycopene content in tomatoes can be achieved by using a portable chroma meter, with a possible field usage application. Equations to calculate the lycopene content of tomatoes based on the color readings are reported.

    1993-01-01

    A heating analysis for a 15.2 m diameter Lunar Transfer Vehicle (LTV) at 0 and 10.6 deg angle of attack for a nominal trajectory through the earth's atmosphere is described. The analysis utilizes the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) with thin-layer, Navier-Stokes, thermochemical nonequilibrium options. Radiative heating levels are calculated using the Langley Optimized RAdiative Nonequilibrium (LORAN) and the Non-EQuilibrium AIr Radiation (NEQAIR) codes. At peak heating, the shock layer is substantially in equilibrium. Comprehensive spatial and spectral grid convergence studies have been implemented to quantify grid effects on the convective and radiative heating levels. Axisymmetric tests including the coupled effects of radiative energy transfer show negligible change to the convective heating and a 20 percent reduction in the radiative heating.

  1. Statistical Modeling of Robotic Random Walks on Different Terrain

    Naylor, Austin; Kinnaman, Laura

    Issues of public safety, especially with crowd dynamics and pedestrian movement, have been modeled by physicists using methods from statistical mechanics over the last few years. Complex decision making of humans moving on different terrains can be modeled using random walks (RW) and correlated random walks (CRW). The effect of different terrains, such as a constant increasing slope, on RW and CRW was explored. LEGO robots were programmed to make RW and CRW with uniform step sizes. Level ground tests demonstrated that the robots had the expected step size distribution and correlation angles (for CRW). The mean square displacement was calculated for each RW and CRW on different terrains and matched expected trends. The step size distribution was determined to change based on the terrain; theoretical predictions for the step size distribution were made for various simple terrains. It's Dr. Laura Kinnaman, not sure where to put the Prefix.

  9. Blurring the Inputs: A Natural Language Approach to Sensitivity Analysis

    NASA Technical Reports Server (NTRS)

    2007-01-01

    To document model parameter uncertainties and to automate sensitivity analyses for numerical simulation codes, a natural-language-based method to specify tolerances has been developed. With this new method, uncertainties are expressed in a natural manner, i.e., as one would on an engineering drawing, namely, 5.25 +/- 0.01. This approach is robust and readily adapted to various application domains because it does not rely on parsing the particular structure of input file formats. Instead, tolerances of a standard format are added to existing fields within an input file. As a demonstration of the power of this simple, natural language approach, a Monte Carlo sensitivity analysis is performed for three disparate simulation codes: fluid dynamics (LAURA), radiation (HARA), and ablation (FIAT). Effort required to harness each code for sensitivity analysis was recorded to demonstrate the generality and flexibility of this new approach.

    Riley, Christropher J.; Kleb, William L.

    1998-01-01

    Radiative equilibrium surface temperatures and surface heating rates from a combined inviscid-boundary layer method are presented for the X-34 Reusable Launch Vehicle for several points along the hypersonic descent portion of its trajectory. Inviscid, perfect-gas solutions are generated with the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) and the Data-Parallel Lower-Upper Relaxation (DPLUR) code. Surface temperatures and heating rates are then computed using the Langley Approximate Three-Dimensional Convective Heating (LATCH) engineering code employing both laminar and turbulent flow models. The combined inviscid-boundary layer method provides accurate predictions of surface temperatures over most of the vehicle and requires much less computational effort than a Navier-Stokes code. This enables the generation of a more thorough aerothermal database which is necessary to design the thermal protection system and specify the vehicle's flight limits.

    Nine new species of Ogyges Kaup (Coleoptera: Passalidae) from the mountainous cloud forests of Mesoamerica are described: O. handali new species and O. menchuae new species from Guatemala; O. cavei new species, O. laurae new species, O. llama new species, O. mutenroshii new species, O. ratcliffei new species, and O. toriyamai new species from Honduras; and O. sandinoi new species from Nicaragua, the first objective record of the genus for this country. A key to the adult Ogyges is included. The work also shows that Ogyges possesses an exclusive autapomorphy: a trituberculate suprainternal tooth of each mandible (one long and wide apical tubercle and two connected, small, almost conical, basal tubercles). This character state is found in all known Ogyges species and is proposed as a synapomorphy that supports the monophyly of the genus.

    Genomic Signature Tags (GSTs) are the products of a method we have developed for identifying and quantitatively analyzing genomic DNAs. The DNA is initially fragmented with a type II restriction enzyme. An oligonucleotide adaptor containing a recognition site for MmeI, a type IIS restriction enzyme, is then used to release 21-bp tags from fixed positions in the DNA relative to the sites recognized by the fragmenting enzyme. These tags are PCR-amplified, purified, concatenated and then cloned and sequenced. The tag sequences and abundances are used to create a high resolution GST sequence profile of the genomic DNA.

  14. Disembodiment and Identity in Literary Depictions of Epilepsy Surgery.

    2015-01-01

    This article explores the often perplexing experience of being an epilepsy surgery candidate, as portrayed in four book-length accounts: Laura Doermer's Moritz mein Sohn (Moritz my son, 1990), David B.'s L'ascension du haut mal (The ascent of the high evil, 1996; published in English as Epileptic, 2003), Ray Robinson's Electricity (2006), and Alberto Capitta's Il giardino non esiste (The garden doesn't exist, 2009). Building upon critical disability studies and the work of French poststructuralists Gilles Deleuze and Félix Guattari, I analyze issues of embodiment, identity and narrative (re)construction in the postsurgical alleviation of chronic illness. I argue that these texts highlight the inevitable disruption of self that brain surgery entails and ultimately resist biomedical normativization. They also call for a narratological reconsideration of current illness narrative typologies, among which Arthur Frank's "chaos narrative" emerges as the best suited to accommodate the chronic fragmentation of consciousness and voice in epilepsy.

    The endemic Australasian species of Ypsiloncyphon are the sister group of the combined Asian species groups 1, 2, and 4. The description of the type species, Y. chlorizans (Klausnitzer), is supplemented by details of male and female genitalia. New species are described and illustrated in several genera: Austrocyphon scissus n. sp., Leptocyphon abnormis n. sp., Petrocyphon bonang n. sp., P. lacteus n. sp., P. televisionarius n. sp., Prionocyphon bidentatus n. sp., P. cacatua n. sp., P. laurae n. sp., P. neboissi n. sp., P. serratus n. sp., P. uncatus n. sp., and P. urbanus n. sp. Genus Prionocyphon is distinguished from Oriental genera with similar antennal modifications. However, a synapomorphy of Prionocyphon as presently understood is not known. Supplementary information on various species in the aforementioned genera and in Pachycyphon and Calvarium is provided. A key to the genera of adult Australian Scirtidae: Scirtinae is presented.

  16. The Hawthorne experiments and the introduction of Jean Piaget in American industrial psychology, 1929-1932.

    2002-05-01

    The Hawthorne interview program between 1929 and 1932 was one of the most significant industrial studies in the United States. The Hawthorne researchers applied Jean Piaget's clinical method in their extensive interviews with tens of thousands of workers. Chiefly responsible for the program's methodology was Elton Mayo, an Australian who saw interviewing as a means to promote social cooperation. Previous discussions of the Hawthorne experiments have ignored the influence of Piaget in the social sciences. This article provides an account of Mayo's and the Hawthorne researchers' efforts to fuse Piaget's innovation with burgeoning American industrial psychology. The endeavor was not an isolated event but rather drew on the theories and practice of Janet-Piaget psychology, on the support of the Laura Spelman Rockefeller Memorial Foundation, and on the discourse among social scientists about Piaget's work.

    In this primer, we give a review of the inverse problem for EEG source localization. This is intended for the researchers new in the field to get insight in the state-of-the-art techniques used to find approximate solutions of the brain sources giving rise to a scalp potential recording. Furthermore, a review of the performance results of the different techniques is provided to compare these different inverse solutions. The authors also include the results of a Monte-Carlo analysis which they performed to compare four non parametric algorithms and hence contribute to what is presently recorded in the literature. An extensive list of references to the work of other researchers is also provided. This paper starts off with a mathematical description of the inverse problem and proceeds to discuss the two main categories of methods which were developed to solve the EEG inverse problem, mainly the non parametric and parametric methods. The main difference between the two is to whether a fixed number of dipoles is assumed a priori or not. Various techniques falling within these categories are described including minimum norm estimates and their generalizations, LORETA, sLORETA, VARETA, S-MAP, ST-MAP, Backus-Gilbert, LAURA, Shrinking LORETA FOCUSS (SLF), SSLOFO and ALF for non parametric methods and beamforming techniques, BESA, subspace techniques such as MUSIC and methods derived from it, FINES, simulated annealing and computational intelligence algorithms for parametric methods. From a review of the performance of these techniques as documented in the literature, one could conclude that in most cases the LORETA solution gives satisfactory results. In situations involving clusters of dipoles, higher resolution algorithms such as MUSIC or FINES are however preferred. Imposing reliable biophysical and psychological constraints, as done by LAURA has given superior results.

    Water resources in small islands, such as atoll islands, are limited and threatened by climate change such as changes in precipitation and sea level rise. Groundwater is the main water resources in many atoll islands, and the freshwater in aquifers in coral atolls, where the average elevations are a few meters above the sea level, exists as lenses f1oating on salt water. Decrease in precipitation and groundwater recharge is caused by the climate change, increases of storm surge, and excessive groundwater extractions due to over population. There is high possibility that the aquifer salinization can damage the important natural ambience for the people living habitat such as crops field and vegetation. In this study, the aquifer salinization is evaluated by using electrical resistivity, hydrological and long-term meteorological data in two low-lying coral atolls, Laura islet, Majuro Atoll, Marshall islands and Fongafale islet, Funafuti atoll, Tuvalu. Hydrological surveys conducted in Laura islet showed that the interface between seawater and freshwater is shallowed in Aug 2009. This may be attributed to the result of recent decrease of the decadal rainfall and/or the sea level rise. The detailed structure of the freshwater lens based on the electrical resistivity surveys showed patches of brackish water due to the intrusion of seawater and over-pumping. The clear intrusion of the saltwater was observed near the lagoon coast which might be inf1uenced by the recirculation of the seawater in the margin of the freshwater lens. The recirculation was confirmed based on the analysis of the submarine groundwater discharge (SGD) observed by seepage meters. On the other hand, in Fongatale islet, the geoelectric and hydrological surveys conducted in March 2009 showed that the soil and groundwater salinization was mainly caused by the tidal forcing during spring tides. The decrease of the resistivity during the f1ood tide indicates the coastal aquifer beneath the islet is

  2. A Comparison of EAST Shock-Tube Radiation Measurements with a New Air Radiation Model

    Johnston, Christopher O.

    2008-01-01

    This paper presents a comparison between the recent EAST shock tube radiation measurements (Grinstead et al., AIAA 2008-1244) and the HARA radiation model. The equilibrium and nonequilibrium radiation measurements are studied for conditions relevant to lunar-return shock-layers; specifically shock velocities ranging from 9 to 11 kilometers per second at initial pressures of 0.1 and 0.3 Torr. The simulated shock-tube flow is assumed one-dimensional and is calculated using the LAURA code, while a detailed nonequilibrium radiation prediction is obtained in an uncoupled manner from the HARA code. The measured and predicted intensities are separated into several spectral ranges to isolate significant spectral features, mainly strong atomic line multiplets. The equations and physical data required for the prediction of these strong atomic lines are reviewed and their uncertainties identified. The 700-1020 nm wavelength range, which accounts for roughly 30% of the radiative flux to a peak-heating lunar return shock-layer, is studied in detail and the measurements and predictions are shown to agree within 15% in equilibrium. The plus or minus 1.5% uncertainty on the measured shock velocity is shown to cause up to a plus or minus 30% difference in the predicted radiation. This band of predictions contains the measured values in almost all cases. For the highly nonequilibrium 0.1 Torr cases, the nonequilibrium radiation peaks are under-predicted by about half. This under-prediction is considered acceptable when compared to the order-of-magnitude over-prediction obtained using a Boltzmann population of electronic states. The reasonable comparison in the nonequilibrium regions provides validation for both the non-Boltzmann modeling in HARA and the thermochemical nonequilibrium modeling in LAURA. The N2 (+)(1-) and N2(2+) molecular band systems are studied in the 290 480 nm wavelength range for both equilibrium and nonequilibrium regimes. The non-Boltzmann rate models for these

    Flow in a pressurized, vapor condensation (PVC) boron nitride nanotube (BNNT) production rig is modeled. A laser provides a thermal energy source to the tip of a boron ber bundle in a high pressure nitrogen chamber causing a plume of boron-rich gas to rise. The buoyancy driven flow is modeled as a mixture of thermally perfect gases (B, B2, N, N2, BN) in either thermochemical equilibrium or chemical nonequilibrium assuming steady-state melt and vaporization from a 1 mm radius spot at the axis of an axisymmetric chamber. The simulation is intended to define the macroscopic thermochemical environment from which boron-rich species, including nanotubes, condense out of the plume. Simulations indicate a high temperature environment (T > 4400K) for elevated pressures within 1 mm of the surface sufficient to dissociate molecular nitrogen and form BN at the base of the plume. Modifications to Program LAURA, a finite-volume based solver for hypersonic flows including coupled radiation and ablation, are described to enable this simulation. Simulations indicate that high pressure synthesis conditions enable formation of BN vapor in the plume that may serve to enhance formation of exceptionally long nanotubes in the PVC process.

    Introduction The accompanying article, written by John Murphy, a retired lawyer and lifelong outdoorsman from his beloved Colorado Rockies, draws the striking parallel between his experiences as a mountain climber and as a patient with metastatic melanoma facing the hope and uncertainty of experimental therapy. Both are life-threatening circumstances, demanding courage and hope, and challenging our soul in a way almost unique to human experience. Both involve a conscious choice to move forward into dangerous and uncertain territory, and require a determination to look death (John's “Reaper”) in the eye. Many remarkable books and films have been written about such experiences. I recall in particular the 2003 documentary film Touching the Void, about the incredible survival of a mountaineer who returned from a perilous fall in Peru. I highly recommend it to the reader. Another is Laura Hillenbrand's Unbroken: A World War II Story of Survival, Resilience, and Redemption (Random House, 2010), about the survival of a prisoner of war, the celebrated miler Louis Zamperini. Again, unbridled courage and undeniable hope turned futility into future. John Murphy's reflections remind us of the daily heroism of our patients who are holding tight to the lifeline offered by clinical research. Good climbing, John. All of us are with you on that Knife Edge, waiting for our turn to ascend... and hoping to be as courageous as you were then on Capitol Peak and are again now on the Knife Edge of a clinical trial. For our turn will come. PMID:21349953

    The goal of my project was to create a graphical user interface for a prototype crop scheduler. The crop scheduler was developed by Dr. Jorge Leon and Laura Whitaker for the ALSS (Advanced Life Support System) program. The addition of a system-independent graphical user interface to the crop planning tool will make the application more accessible to a wider range of users and enhance its value as an analysis, design, and planning tool. My presentation will demonstrate the form and functionality of this interface. This graphical user interface allows users to edit system parameters stored in the file system. Data on the interaction of the crew, crops, and waste processing system with the available system resources is organized and labeled. Program output, which is stored in the file system, is also presented to the user in performance-time plots and organized charts. The menu system is designed to guide the user through analysis and decision making tasks, providing some help if necessary. The Java programming language was used to develop this interface in hopes of providing portability and remote operation.

    A systematic approach for calibrating the direct simulation Monte Carlo (DSMC) collision model parameters to achieve consistency in the transport processes is presented. The DSMC collision cross section model parameters are calibrated for high temperature atmospheric conditions by matching the collision integrals from DSMC against ab initio based collision integrals that are currently employed in the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) and Data Parallel Line Relaxation (DPLR) high temperature computational fluid dynamics solvers. The DSMC parameter values are computed for the widely used Variable Hard Sphere (VHS) and the Variable Soft Sphere (VSS) models using the collision-specific pairing approach. The recommended best-fit VHS/VSS parameter values are provided over a temperature range of 1000-20 000 K for a thirteen-species ionized air mixture. Use of the VSS model is necessary to achieve consistency in transport processes of ionized gases. The agreement of the VSS model transport properties with the transport properties as determined by the ab initio collision integral fits was found to be within 6% in the entire temperature range, regardless of the composition of the mixture. The recommended model parameter values can be readily applied to any gas mixture involving binary collisional interactions between the chemical species presented for the specified temperature range.

    Surface temperature measurements from the STS-119 boundary-layer transition experiment on the space shuttle orbiter Discovery provide a rare opportunity to assess turbulent CFD models at hypersonic flight conditions. This flight data was acquired by on-board thermocouples and by infrared images taken off-board by the Hypersonic Thermodynamic Infrared Measurements (HYTHIRM) team, and is suitable for hypersonic CFD turbulence assessment between Mach 6 and 14. The primary assessment is for the Baldwin-Lomax and Cebeci-Smith algebraic turbulence models in the DPLR and LAURA CFD codes, respectively. A secondary assessment is made of the Shear-Stress Transport (SST) two-equation turbulence model in the DPLR code. Based upon surface temperature comparisons at eleven thermocouple locations, the algebraic-model turbulent CFD results average 4% lower than the measurements for Mach numbers less than 11. For Mach numbers greater than 11, the algebraic-model turbulent CFD results average 5% higher than the three available thermocouple measurements. Surface temperature predictions from the two SST cases were consistently 3 4% higher than the algebraic-model results. The thermocouple temperatures exhibit a change in trend with Mach number at about Mach 11; this trend is not reflected in the CFD results. Because the temperature trends from the turbulent CFD simulations and the flight data diverge above Mach 11, extrapolation of the turbulent CFD accuracy to higher Mach numbers is not recommended.

  15. Cultural variation is part of human nature : Literary universals, context-sensitivity, and "shakespeare in the bush".

    PubMed

    2003-12-01

    In 1966, Laura Bohannan wrote her classic essay challenging the supposition that great literary works speak to universal human concerns and conditions and, by extension, that human nature is the same everywhere. Her evidence: the Tiv of West Africa interpret Hamlet differently from Westerners. While Bohannan's essay implies that cognitive universality and cultural variation are mutually exclusive phenomena, adaptationist theory suggests otherwise. Adaptive problems ("the human condition") and cognitive adaptations ("human nature") are constant across cultures. What differs between cultures is habitat: owing to environmental variation, the means and information relevant to solving adaptive problems differ from place to place. Thus, we find differences between cultures not because human minds differ in design but largely because human habitats differ in resources and history. On this view, we would expect world literature to express both human universals and cultural particularities. Specifically, we should expect to find literary universality at the macro level (e.g., adaptive problems, cognitive adaptations) and literary variation at the micro level (e.g., local solutions to adaptive problems).

    The Sex and Gender Medical Education Summit: a roadmap for curricular innovation was a collaborative initiative of the American Medical Women's Association, Laura W. Bush Institute for Women's Health, Mayo Clinic, and Society for Women's Health Research (www.sgbmeducationsummit.com). It was held on October 18-19, 2015 to provide a unique venue for collaboration among nationally and internationally renowned experts in developing a roadmap for the incorporation of sex and gender based concepts into medical education curricula. The Summit engaged 148 in-person attendees for the 1 1/2-day program. Pre- and post-Summit surveys assessed the impact of the Summit, and workshop discussions provided a framework for informal consensus building. Sixty-one percent of attendees indicated that the Summit had increased their awareness of the importance of sex and gender specific medicine. Other comments indicate that the Summit had a significant impact for motivating a call to action among attendees and provided resources to initiate change in curricula within their home institutions. These educational efforts will help to ensure a sex and gender basis for delivery of health care in the future.

  18. Gendered Obstacles Faced by Historical Women in Physics and Astronomy

    A gender gap still exists in modern science; this is especially evident in the fields of physics and astronomy. The cause of such a gap is the center of debate. Is this discrepancy the result of inherent ability or socialization? Most studies have focused on modern issues and how women are socialized today. The role of historical gender perspectives and social opinions in creating the field of modern science and any discrepancies within it has not yet been explored in depth. This project investigates the obstacles faced by historical women in physics and astronomy that stem from the officialized gender biases that accompanied the establishment of modern science. Such obstacles are both formal and informal. Four women were chosen to span the three hundred year period between the standardization of the field and the modern day: Laura Bassi, Mary Somerville, Lise Meitner, and Jocelyn Bell Burnell. The investigation reveals that formal obstacles significantly decreased over the time period, while informal obstacles eroded more gradually. Obstacles also reflected historical events such as the World Wars and the Enlightenment. Trends in obstacles faced by four prominent women physicists indicate that education, finances, support networks, and social opinion played a large role in determining success in the field. The applicability to modern day physics issues and the gender gap is discussed. Many thanks to the Pathways Scholars Program and the Ronald E. McNair Post-Baccalaureate Achievement Program for funding for this project.

    The symposium dedicated to Gerbert on 12.52012 was held at the Vallicelliana Library, in the Borromini hall. The title was Gerberto and Borromini, in order to evidence the link between Gerbert (938 ca. - 1003) and the Ticinese architect who saved his tumb, during the restauration of the Cathedral of Rome St. John in Laterano in 1648. It is possibile that from his residence in the Lateran Gerbert could observe the stars with his tubes, which are presented by C. Sigismondi in this volume. During his trips to Italy, alone and following the archbishop Adalbero of Reims Gerbert could have passed in the Chiusa Valley and influence with his astronomical knowledges the builders of the Sacra of S. Michele, this is the subject of Laura C. Paladino study. Abbo of Fleury is contemporary to Gerbert and he had the same vast interests. He studied in England and they are presented together in the paper of Paolo Rossi. Veronica Regoli shows the link between Gerbert, Dante and Jerusalem.

    Low- and zero-moment half-metallic ferrimagnetic semiconductors have been proposed for advanced applications, such as nonvolatile RAM memory and quantum computing. These inverse-Heusler materials could be used to generate spin-polarized electron or hole currents without the associated harmful fringing magnetic fields. Such materials are expected to exhibit low to zero magnetic moment at room temperature, which makes them well-positioned for future spin-based devices. However, these compounds have been shown to suffer from disorder. This work focuses on the synthesis of these compounds and the investigation of their structural, magnetic, and transport properties. Cr2CoGa and Mn3Al thin films were synthesized by molecular beam epitaxy, and V3Al and Cr2CoAl were synthesized via arc-melting. Rietveld analysis was used to determine the degree of ordering in the sublattices as a function of annealing. The atomic moments were measured by X-ray magnetic circular and linear dichroism confirmed antiferromagnetic alignment of sublattices and the desired near-zero moment in several compounds.

  2. Steps towards a phylogeny of the pill millipedes: non-monophyly of the family Protoglomeridae, with an integrative redescription of Eupeyerimhoffia archimedis (Diplopoda, Glomerida)

    2015-01-01

    Abstract Eupeyerimhoffia archimedis (Strasser, 1965) is redescribed based on several specimens collected at a number of sites close to the type locality on Sicily, Italy. Scanning electron microscopy is used to illustrate several unusual morphological characters for a member of the Glomerida for the first time. A fragment of the mitochondrial COI gene (668bp) is sequenced for the first time in Eupeyerimhoffia to provide a species-specific barcode and to gain first insights into the genetic distances between the genera in the widespread family Protoglomeridae. The novel sequences are compared to representatives of all other genera of the family: Protoglomeris vasconica (Brölemann, 1897) from northern Spain, the dwarfed Glomerellina laurae Silvestri, 1908 from Italy and Glomeroides primus (Silvestri, 1929) from western North America. The addition of COI sequences from the two other families of the Glomerida renders the family Protoglomeridae paraphyletic with Glomeroides primus being more closely related to Glomeridella minima (Latzel, 1884) than to the other genera in the family. The large genetic distances (13.2–16.8%) between Eupeyerimhoffia and the other genera in the order, as well as its unusual morphological characters, including unique morphological adaptations to roll into a ball, are probably an indication of the old age of the group.

    Interaction between the external flowfield and the reaction control system (RCS) thruster plumes of the Phoenix capsule during entry has been investigated. The analysis covered rarefied, transitional, hypersonic and supersonic flight regimes. Performance of pitch, yaw and roll control authority channels was evaluated, with specific emphasis on the yaw channel due to its low nominal yaw control authority. Because Phoenix had already been constructed and its RCS could not be modified before flight, an assessment of RCS efficacy along the trajectory was needed to determine possible issues and to make necessary software changes. Effectiveness of the system at various regimes was evaluated using a hybrid DSMC-CFD technique, based on DSMC Analysis Code (DAC) code and General Aerodynamic Simulation Program (GASP), the LAURA (Langley Aerothermal Upwind Relaxation Algorithm) code, and the FUN3D (Fully Unstructured 3D) code. Results of the analysis at hypersonic and supersonic conditions suggest a significant aero-RCS interference which reduced the efficacy of the thrusters and could likely produce control reversal. Very little aero-RCS interference was predicted in rarefied and transitional regimes. A recommendation was made to the project to widen controller system deadbands to minimize (if not eliminate) the use of RCS thrusters through hypersonic and supersonic flight regimes, where their performance would be uncertain.

  4. Approach for a Global Height Reference System

    Hermann Drewes, Christoph Foerste, Thomas Gruber, Gunter Liebsch, Roland Pail, Laura Sanchez For Earth system monitoring the heights are main parameters for global changes. Physical heights are potential differences of the outer Earth gravity field at different positions. Long term monitoring of the vertical component of the Earth surface needs a standardized defined and realized global reference relating the geometry and the gravity field of the Earth. In the last two decades, in several working groups of the International Association of Geodesy were different concepts for definition and realization of global height reference system discussed. Furthermore, the satellite gravity missions have the Earth gravity field data basis general extended. So far, it is possible to develop the present local and regional height reference systems concepts to a global approach. The presented proposal has to be understood as a model that consider the present possibilities and actual needs for the realization of a global height reference system. It includes aspects for the combination of observations and products representing the geometry and the gravity field of the Earth.

  5. Nonequilibrium radiative heating prediction method for aeroassist flowfields with coupling to flowfield solvers. Ph.D. Thesis

    Hartung, Lin C.

    1991-01-01

    A method for predicting radiation adsorption and emission coefficients in thermochemical nonequilibrium flows is developed. The method is called the Langley optimized radiative nonequilibrium code (LORAN). It applies the smeared band approximation for molecular radiation to produce moderately detailed results and is intended to fill the gap between detailed but costly prediction methods and very fast but highly approximate methods. The optimization of the method to provide efficient solutions allowing coupling to flowfield solvers is discussed. Representative results are obtained and compared to previous nonequilibrium radiation methods, as well as to ground- and flight-measured data. Reasonable agreement is found in all cases. A multidimensional radiative transport method is also developed for axisymmetric flows. Its predictions for wall radiative flux are 20 to 25 percent lower than those of the tangent slab transport method, as expected, though additional investigation of the symmetry and outflow boundary conditions is indicated. The method was applied to the peak heating condition of the aeroassist flight experiment (AFE) trajectory, with results comparable to predictions from other methods. The LORAN method was also applied in conjunction with the computational fluid dynamics (CFD) code LAURA to study the sensitivity of the radiative heating prediction to various models used in nonequilibrium CFD. This study suggests that radiation measurements can provide diagnostic information about the detailed processes occurring in a nonequilibrium flowfield because radiation phenomena are very sensitive to these processes.

  6. Considerations for building climate-based species distribution models

    Climate plays an important role in the distribution of species. A given species may adjust to new conditions in-place, move to new areas with suitable climates, or go extinct. Scientists and conservation practitioners use mathematical models to predict the effects of future climate change on wildlife and plan for a biodiverse future. This 8-page fact sheet written by David N. Bucklin, Mathieu Basille, Stephanie S. Romañach, Laura A. Brandt, Frank J. Mazzotti, and James I. Watling and published by the Department of Wildlife Ecology and Conservation explains how, with a better understanding of species distribution models, we can predict how species may respond to climate change. The models alone cannot tell us how a certain species will actually respond to changes in climate, but they can inform conservation planning that aims to allow species to both adapt in place and (for those that are able to) move to newly suitable areas. Such planning will likely minimize loss of biodiversity due to climate change.

  7. Multi-Component Diffusion with Application To Computational Aerothermodynamics

    Sutton, Kenneth; Gnoffo, Peter A.

    1998-01-01

    The accuracy and complexity of solving multicomponent gaseous diffusion using the detailed multicomponent equations, the Stefan-Maxwell equations, and two commonly used approximate equations have been examined in a two part study. Part I examined the equations in a basic study with specified inputs in which the results are applicable for many applications. Part II addressed the application of the equations in the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) computational code for high-speed entries in Earth's atmosphere. The results showed that the presented iterative scheme for solving the Stefan-Maxwell equations is an accurate and effective method as compared with solutions of the detailed equations. In general, good accuracy with the approximate equations cannot be guaranteed for a species or all species in a multi-component mixture. 'Corrected' forms of the approximate equations that ensured the diffusion mass fluxes sum to zero, as required, were more accurate than the uncorrected forms. Good accuracy, as compared with the Stefan- Maxwell results, were obtained with the 'corrected' approximate equations in defining the heating rates for the three Earth entries considered in Part II.

Moreover, being based on Italian sources from the nineteenth century, the study offers an historical insight on the Italian nation-building process and its political and social foundations. This study is based on archival and printed primary sources from: Gianna Maffei and Ercole Trotti Mosti (Museo Centrale del Risorgimento - Roma - MCRR); Augusto Pierantoni and Grazia Mancini (Museo Centrale del Risorgimento - Roma); Luigi Majno and Ersilia Bronzini (Archivio Unione Femminile Nazionale - Milano); Angiolo Orvieto and Laura Cantoni (Archivio Contemporaneo Bonsanti del Gabinetto Vieuesseux - Firenze - ACGV). This study reflects on love as a political and moral issue, by linking the personal sphere of subjectivity to the public dimension of the political community. An extensive understanding of the role played by the perception and the expression of sentiments can be considered as the central issue of this analysis.

  9. Assessment of CFD Hypersonic Turbulent Heating Rates for Space Shuttle Orbiter

    Wood, William A.; Oliver, A. Brandon

    2011-01-01

    Turbulent CFD codes are assessed for the prediction of convective heat transfer rates at turbulent, hypersonic conditions. Algebraic turbulence models are used within the DPLR and LAURA CFD codes. The benchmark heat transfer rates are derived from thermocouple measurements of the Space Shuttle orbiter Discovery windward tiles during the STS-119 and STS-128 entries. The thermocouples were located underneath the reaction-cured glass coating on the thermal protection tiles. Boundary layer transition flight experiments conducted during both of those entries promoted turbulent flow at unusually high Mach numbers, with the present analysis considering Mach 10{15. Similar prior comparisons of CFD predictions directly to the flight temperature measurements were unsatisfactory, showing diverging trends between prediction and measurement for Mach numbers greater than 11. In the prior work, surface temperatures and convective heat transfer rates had been assumed to be in radiative equilibrium. The present work employs a one-dimensional time-accurate conduction analysis to relate measured temperatures to surface heat transfer rates, removing heat soak lag from the flight data, in order to better assess the predictive accuracy of the numerical models. The turbulent CFD shows good agreement for turbulent fuselage flow up to Mach 13. But on the wing in the wake of the boundary layer trip, the inclusion of tile conduction effects does not explain the prior observed discrepancy in trends between simulation and experiment; the flight heat transfer measurements are roughly constant over Mach 11-15, versus an increasing trend with Mach number from the CFD.

  10. Female science teacher beliefs and attitudes: implications in relation to gender and pedagogical practice

    2007-10-01

    Beliefs and attitudes resulting from the unique life experiences of teachers frame interactions with learners promoting gender equity or inequity and the reproduction of social views about knowledge and power as related to gender. This study examines the enactment of a female science teacher's pedagogy (Laura), seeking to understand the implications of her beliefs and attitudes, as framed by her interpretations and daily manifestations, as she interacts with students. Distinct influences inform the conceptual framework of this study: (a) the social organization of society at large, governed by understood and unspoken patriarchy, present both academically and socially; (b) the devaluing of women as "knowers" of scientific knowledge as defined by a western and male view of science; (c) the marginalization or "feminization" of education and pedagogical knowledge. The findings reflect tensions between attitudes and beliefs and actual teacher practice suggesting the need for awareness within existing or new teachers about their positions as social agents and the sociological implications related to issues of gender within which we live and work, inclusive of science teaching and learning.

Kelson, Lucas M. Macri, Barry F. Madore, Shoko Sakai, Kim M. Sebo, Nancy A. Silbermann, and Peter B. Stetson, some sign errors need to be corrected. 1. In equation (A2) the minus signs should be plus signs. The correct version is Vcosmic=VH+Vc,LG+Vin,Virgo+Vin,GA+Vin,Shap+... 2. In Table A1 the declination of the Great Attractor (GA) is -44°, and that of the Shapley supercluster is -31°, i.e., south declination, not north, as implied in the table. The first error is the authors' and the second occurred in the publication process. In both cases the computer code was correct, and the errors are in the published representation. None of the results presented in the paper are therefore affected in any way. The authors thank Dr. Jim Condon for pointing out the error in equation (A2)

  12. Radiation Coupling with the FUN3D Unstructured-Grid CFD Code

    2012-01-01

    The HARA radiation code is fully-coupled to the FUN3D unstructured-grid CFD code for the purpose of simulating high-energy hypersonic flows. The radiation energy source terms and surface heat transfer, under the tangent slab approximation, are included within the fluid dynamic ow solver. The Fire II flight test, at the Mach-31 1643-second trajectory point, is used as a demonstration case. Comparisons are made with an existing structured-grid capability, the LAURA/HARA coupling. The radiative surface heat transfer rates from the present approach match the benchmark values within 6%. Although radiation coupling is the focus of the present work, convective surface heat transfer rates are also reported, and are seen to vary depending upon the choice of mesh connectivity and FUN3D ux reconstruction algorithm. On a tetrahedral-element mesh the convective heating matches the benchmark at the stagnation point, but under-predicts by 15% on the Fire II shoulder. Conversely, on a mixed-element mesh the convective heating over-predicts at the stagnation point by 20%, but matches the benchmark away from the stagnation region.

    2009-01-01

    An investigation of effectiveness of the reaction control system (RCS) of Mars Science Laboratory (MSL) entry capsule during atmospheric flight has been conducted. The reason for the investigation is that MSL is designed to fly a lifting actively guided entry with hypersonic bank maneuvers, therefore an understanding of RCS effectiveness is required. In the course of the study several jet configurations were evaluated using Langley Aerothermal Upwind Relaxation Algorithm (LAURA) code, Data Parallel Line Relaxation (DPLR) code, Fully Unstructured 3D (FUN3D) code and an Overset Grid Flowsolver (OVERFLOW) code. Computations indicated that some of the proposed configurations might induce aero-RCS interactions, sufficient to impede and even overwhelm the intended control torques. It was found that the maximum potential for aero-RCS interference exists around peak dynamic pressure along the trajectory. Present analysis largely relies on computational methods. Ground testing, flight data and computational analyses are required to fully understand the problem. At the time of this writing some experimental work spanning range of Mach number 2.5 through 4.5 has been completed and used to establish preliminary levels of confidence for computations. As a result of the present work a final RCS configuration has been designed such as to minimize aero-interference effects and it is a design baseline for MSL entry capsule.

    β- and isomer-decay spectroscopy are sensitive probes of nuclear structure, and are often the only techniques capable of providing data for exotic nuclei that are producted with very low rates. Decay properties of exotic nuclei are also essential to model astrophysical events responible for the evolution of the universe such as the rp- and r-process. The EURICA project (EUROBALL RIKEN Cluster Array) has been launched in 2012 with the goal of performing spectroscopy of very exotic nuclei. Since 2012, four experimental campaigns have been successfully completed using fragmentation of 124Xe beam and in-flight-fission of 238U beam, approaching for example the key nuclei 78Ni, 110Zr, 100Sn, 128Pd, and 138Sn. This contribution highlights the experiments performed, results obtained, and discusses the future perspective of the EURICA project.

    DOE Data Explorer

    Ronald, Pamela

    The Ronald Laboratory staff at the University of California-Davis has a primary research focus on the genes of the rice plant. They study the role that genetics plays in the way rice plants respond to their environment. They created the Rice GT Database in order to integrate functional genomic information for putative rice Glycosyltransferases (GTs). This database contains information on nearly 800 putative rice GTs (gene models) identified by sequence similarity searches based on the Carbohydrate Active enZymes (CAZy) database. The Rice GT Database provides a platform to display user-selected functional genomic data on a phylogenetic tree. This includes sequence information, mutant line information, expression data, etc. An interactive chromosomal map shows the position of all rice GTs, and links to rice annotation databases are included. The format is intended to "facilitate the comparison of closely related GTs within different families, as well as perform global comparisons between sets of related families."

    Functional electrical neuroimaging investigated incidental emotional word processing. Previous research suggests that the brain may differentially respond to the emotional content of linguistic stimuli pre-lexically (i.e., before distinguishing that these stimuli are words). We investigated the spatiotemporal brain mechanisms of this apparent paradox and in particular whether the initial differentiation of emotional stimuli is marked by different brain generator configurations using high-density, event-related potentials. Such would support the existence of specific cerebral resources dedicated to emotional word processing. A related issue concerns the possibility of right-hemispheric specialization in the processing of emotional stimuli. Thirteen healthy men performed a go/no-go lexical decision task with bilateral word/non-word or non-word/non-word stimulus pairs. Words included equal numbers of neutral and emotional stimuli, but subjects made no explicit discrimination along this dimension. Emotional words appearing in the right visual field (ERVF) yielded the best overall performance, although the difference between emotional and neutral words was larger for left than for right visual field presentations. Electrophysiologically, ERVF presentations were distinguished from all other conditions over the 100-140 ms period by a distinct scalp topography, indicative of different intracranial generator configurations. A distributed linear source estimation (LAURA) of this distinct scalp potential field revealed bilateral lateral-occipital sources with a right hemisphere current density maximum. These data support the existence of a specialized brain network triggered by the emotional connotation of words at a very early processing stage.

    A three-dimensional aerothermodynamic model of the shuttle orbiter's tile overlay repair (TOR) sub-assembly is presented. This sub-assembly, which is an overlay that covers the damaged tiles, is modeled as a protuberance with a constant thickness. The washers and augers that serve as the overlay fasteners are modeled as cylindrical protuberances with constant thicknesses. Entry aerothermodynamic cases are studied to provide necessary inputs for future thermal analyses and to support the space-shuttle return-to-flight effort. The NASA Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) is used to calculate heat transfer rate on the surfaces of the tile overlay repair and augers. Gas flow is modeled as non-equilibrium, five species air in thermal equilibrium. Heat transfer rate and surface temperatures are analyzed and studied for a shuttle orbiter trajectory point at Mach 17.85. Computational results show that the average heat transfer rate normalized with respect to its value at body point 1800 is about BF=1.9 for the auger head. It is also shown that the average BF for the auger and washer heads is about BF=2.0.

    Computational re-entry aerothermodynamic analysis of the Space Shuttle Orbiter s tile overlay repair (TOR) sub-assembly is presented. Entry aeroheating analyses are conducted to characterize the aerothermodynamic environment of the TOR and to provide necessary inputs for future TOR thermal and structural analyses. The TOR sub-assembly consists of a thin plate and several augers and spacers that serve as the TOR fasteners. For the computational analysis, the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) is used. A 5-species non-equilibrium chemistry model with a finite rate catalytic recombination model and a radiation equilibrium wall condition are used. It is assumed that wall properties are the same as reaction cured glass (RCG) properties with a surface emissivity of epsilon = 0.89. Surface heat transfer rates for the TOR and tile repair augers (TRA) are computed at a STS-107 trajectory point corresponding to Mach 18 free stream conditions. Computational results show that the average heating bump factor (BF), which is a ratio of local heat transfer rate to a design reference point located at the damage site, for the auger head alone is about 1.9. It is also shown that the average BF for the combined auger and washer heads is about 2.0.

    The Faulkes Telescope Project [1] was started in 2000 and is currently managed by the Las Cumbres Observatory Global Telescope Network (LCOGT) [2]. Allows student access to two remote telescopes (in Hawaii and in Australia), allowing you to capture images of the sky. Since January 2012 I conduct monthly observations with students: first with students from Escola Secundária de Loulé (ESL) [3] and starting from September 2013 with students from Agrupamento de Escolas Dra Laura Ayres [4], in Quarteira. Each session is previously prepared in order to make the best of the time available. For that we use a virtual planetarium that allows us to see the sky in place and time of the scheduled session. After the start of each session a student takes control in real time of one of the telescopes from a computer connected to the internet. This project is a tool that gives the students the feeling of doing science and meet the sky step by step. The observations made by my students can be found at www.miguelneta.pt/faulkestelescope.

    The coupled interaction between an ablating surface and the surrounding aerothermal environment is studied. An equilibrium ablation model is coupled to the LAURA flowfield solver, which allows the char ablation rate (m-dot(sub c)) to be computed as part of the flowfield solution. The wall temperature (T(sub w)) and pyrolysis ablation rate (m-dot(sub g)) may be specified by the user, obtained from the steady-state ablation approximation, or computed from a a material response code. A 32 species thermochemical nonequilibrium flowfield model is applied, which permits the treatment of C, H, O, N, and Si containing species. Coupled ablation cases relevant to the Orion heatshield are studied. These consist of diffusion-limited oxidation cases with Avcoat as the ablation material. The m-dot(sub c) values predicted from the developed coupled ablation analysis were compared with those obtained from a typical uncoupled ablation analysis. The coupled results were found to be as much as 50% greater than the uncoupled values. This is shown to be a result of the cumulative effect of the two fundamental approximations inherent in the uncoupled analysis.

    James (Jim) R.Wait, a pioneer in electromagnetic theory and applications to geophysical exploration, died of cancer in Tucson, Arizona, on October 1, 1998. At 74, he was still very active and innovative in electromagnetics as Regents Professor Emeritus, University of Arizona, and as a consultant in electrical geophysics. He is survived by his wife, Gertrude; his son, George; his daughter, Laura; and three grandchildren, James, Carolyn, and Connor.Jim was born in Ottawa, Ontario, Canada, on January 23, 1924. He obtained B.A.Sc.and M.A.Sc. degrees in 1948 and 1949, respectively and his Ph.D. degree in 1951, in electrical engineering, all from the University of Toronto. He obtained his “T” in skiing and remained an avid skier all his life. Jim stayed in great shape and always found time to work out despite his busy schedule. I still remember the business trip where Jim and I ran laps around the parking lot of a Holiday Inn for his daily workout.

  7. Canary in the Coal Mine: Monitoring Indicators and Thresholds of Ecological Integrity

    2010-12-01

    Ecological integrity is the ability of an ecosystem to maintain resilience when disturbed; retain native or natural components and processes; and remain sustainable without external inputs. Ecosystems may be subject to a variety of anthropogenic disturbances from intentional natural resource harvesting such as cattle grazing or timber harvest to unintentional large scale processes including climate change. Monitoring ecological integrity can aid in the prevention of irreversible degradation of a system by identifying indicators to serve as early warning signs of degradation. Our central hypothesis is that changes in ecological integrity and movement towards thresholds may be anticipated through monitoring. Our research objective is to develop efficient and effective methods and indicators for natural resource management. We have collected data for four years (2006-2010) on grazed Wildlife Management Areas in southeastern Washington State using a replicated study design in two ecosystem types stratified by six ecological sites distributed within nine pastures. Methods and metrics were developed from quantitative data (cover, frequency, and species richness), qualitative data (photo monitoring and rangeland health surveys), and desired ecological conditions based on state and transition models and classification systems previously published for the study area. The data are a first step to identify efficient and effective methods and metrics to enable natural resource managers to monitor ecological integrity and identify and avoid crossing irreversible thresholds.

    The diffuse spectra arising from the excess proton in dilute acids suggests that its behavior is highly dependent on the local environment surrounding it. In this work, we report how the spectra of the H3O+, NH4+, and CH3NH3+ ions respond when docked to the rigid, tri-coordinated binding pocket of the 18-crown-6 ether using cryogenic ion vibrational predissociation (CIVP) spectroscopy with D2 tagging at 10 K. The H3O+{tiny^bullet}18-crown-6 ether complex displays a broad (350 cm-1 FWHM) unstructured band arising from the OH stretching fundamentals, which is significantly broader than the corresponding band (125 cm-1 FWHM) in the Eigen cation (H9O4+) spectrum. Perdeuterated isotopologue studies for both systems yield sharper bands with clear multiplet structures, indicating that the broadening arises from nuclear quantum effects. The key displacements underlying this coupling were explored using the vibrationally adiabatic scheme introduced by McCoy in the context of similar broadening in the Ca2+OH-(H2O)n system.

    A multiblock, laminar heating analysis for the shuttle orbiter at three trajectory points ranging from Mach 24.3 to Mach 12.86 on re-entry is described. The analysis is performed using the Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) with both a seven species chemical nonequilibrium model and an equilibrium model. A finite-catalytic-wall model appropriate for shuttle tiles at a radiative equilibrium wall temperature is applied. Computed heating levels are generally in good agreement with the flight data though a few rather large discrepancies remain unexplained. The multiblock relaxation strategy partitions the flowfield into manageable blocks requiring a fraction of the computational resources (time and memory) required by a full domain approach. In hot, the computational cost for a solution at even a single trajectory point would be prohibitively expensive at the given resolution without the multiblock approach. Converged blocks are reassembled to enable a fully coupled converged solution over the entire vehicle, starting from a nearly converged initial condition.

    The Orion aerodynamic database provides force and moment coefficients given the velocity, attitude, configuration, etc. of the Crew Exploration Vehicle (CEV). The database is developed and maintained by the NASA CEV Aerosciences Project team from computational and experimental aerodynamic simulations. The database is used primarily by the Guidance, Navigation, and Control (GNC) team to design vehicle trajectories and assess flight performance. The initial hypersonic re-entry portion of the Crew Module (CM) database was developed in 2006. Updates incorporating additional data and improvements to the database formulation and uncertainty methodologies have been made since then. This paper details the process used to develop the CM database, including nominal values and uncertainties, for Mach numbers greater than 8 and angles of attack between 140deg and 180deg. The primary available data are more than 1000 viscous, reacting gas chemistry computational simulations using both the Laura and Dplr codes, over a range of Mach numbers from 2 to 37 and a range of angles of attack from 147deg to 172deg. Uncertainties were based on grid convergence, laminar-turbulent solution variations, combined altitude and code-to-code variations, and expected heatshield asymmetry. A radial basis function response surface tool, NEAR-RS, was used to fit the coefficient data smoothly in a velocity-angle-of-attack space. The resulting database is presented and includes some data comparisons and a discussion of the predicted variation of trim angle of attack and lift-to-drag ratio. The database provides a variation in trim angle of attack on the order of +/-2deg, and a range in lift-to-drag ratio of +/-0.035 for typical vehicle flight conditions.

    The IDCA conducted a program review at Los Alamos National Laboratory, September 14 and 15, 2010. The review was divided into three parts: 1) an update on the current status of the program, 2) an information exchange and discussion on technical details for current issues and future planning, and 3) a tour of the SSST testing facilities at LANL. The meeting started with an update from DHS by Laura Parker and a restating of some of the objectives of the Proficiency Test of which the IDCA is currently engaged. This update was followed by a discussion of some high level programmatic issues particularly about ways of communicating the overall goals of the IDCA to non-technical representatives. The final topic focused on the difficulty of releasing information, including the DHS approval process, ITAR, and open publication. Next JGR presented a technical summary of accomplishments, schedule, milestones, and future directions. These key points made were: 1) about 1/3 of the materials have been tested, 2) some participants are behind others causing a lag in report writing, 3) method reports have been assigned to various participants to speed up the process of reporting, 4) the SSST Compendium needs reformatting and restructuring, and 5) the Compendium needs a web site to house with access control. After the technical update, some of the Proficiency Test results were shown comparing data from the various laboratories. These results included comparisons of the RDX standard, KC/sugar mixtures (-100 mesh and as received), KC/dodecane, KP/Al, and KP/C. Impact, friction, ESD, and DSC results were the focus. All the participants were involved in these discussions. This report includes summary notes, presentations, and explanatory information.

Stemm1, 1Department of Physics, University of Central Florida, Orlando, Florida, 2Southwest Research Institute, Boulder, Colorado. Impacts and cratering in space play important roles in the formation and evolution of planetary bodies. Low-velocity impacts and disturbances to planetary regolith are also a consequence of manned and robotic exploration of planetary bodies such as the Moon, Mars, and asteroids. We are conducting a program of laboratory experiments to study low-velocity impacts of 1 to 5 m/s into JSC-1 lunar regolith simulant, JSC-Mars-1 Martian regolith simulant, and silica targets under 1 g. We use direct measurement of ejecta mass and high-resolution video tracking of ejecta particle trajectories to derive ejecta mass velocity distributions. Additionally, we conduct similar experiments under microgravity conditions in a laboratory drop tower and on parabolic aircraft with velocities as low as 10 cm/s. We wish to characterize and understand the collision parameters that control the outcome of low-velocity impacts into regolith, including impact velocity, impactor mass, target shape and size distribution, regolith depth, target relative density, and crater depth, and to experimentally determine the functional dependencies of the outcomes of low-velocity collisions (ejecta mass and ejecta velocities) on the controlling parameters of the collision. We present results from our ongoing study showing the positive correlation between impact energy and ejecta mass. The total ejecta mass is also dependent on the packing density (porosity) of the regolith. We find that ejecta mass velocity fits a power-law or broken power-law distribution. Our goal is to understand the physics of ejecta production and regolith compaction in low-energy impacts and experimentally validate predictive models for dust flow and deposition. We will present our

    The results are presented for the stagnation-point heat-transfer rates used in the design process of the Aeroassist Flight Experiment (AFE) vehicle over its entire aeropass trajectory. The prediction methods used in this investigation demonstrate the application of computational fluid dynamics (CFD) techniques to a wide range of flight conditions and their usefulness in a design process. The heating rates were computed by a viscous-shock-layer (VSL) code at the lower altitudes and by a Navier-Stokes (N-S) code for the higher altitude cases. For both methods, finite-rate chemically reacting gas was considered, and a temperature-dependent wall-catalysis model was used. The wall temperature for each case was assumed to be radiative equilibrium temperature, based on total heating. The radiative heating was estimated by using a correlation equation. Wall slip was included in the N-S calculation method, and this method implicitly accounts for shock slip. The N-S/VSL combination of projection methods was established by comparison with the published benchmark flow-field code LAURA results at lower altitudes, and the direct simulation Monte Carlo results at higher altitude cases. To obtain the design heating rate over the entire forward face of the vehicle, a boundary-layer method (BLIMP code) that employs reacting chemistry and surface catalysis was used. The ratio of the VSL or N-S method prediction to that obtained from the boundary-layer method code at the stagnation point is used to define an adjustment factor, which accounts for the errors involved in using the boundary-layer method.

  15. Use of geophysical methods to map subsurface features at levee seepage locations

    NASA Astrophysics Data System (ADS)

    Brackett, Thomas C.

    The Great Flood of 2011 caused moderate to severe seepage and piping along the Mississippi River levees in Northwest Mississippi. The aim of this thesis was to implement geophysical techniques at two seepage locations in order to give a better understanding of the causes of underseepage and information on how to mitigate the problem. Sites near Rena Lara in Coahoma County and near Francis in Bolivar County were chosen to conduct this survey. Electrical Resistivity Tomography (ERT) and Electromagnetic Induction (EM) surveys were conducted on and adjacent to levees to identify seepage pathways and any dominant geological features at the sites. Results from geophysical surveys revealed that Francis and Rena Laura each had a prominent geomorphologic feature that was attributing to underseepage. Seepage at Francis was the result of a sand filled channel capped by a clay overburden. Permeable materials at the base of the channel served as a conduit for transporting river water beneath the levee. The seepage surfaced as sand boils where the overlying clay overburden was thin or non-existent. Investigations at the Rena Lara site revealed a large, clay-filled swale extending beneath the levee. The clay within the swale has relatively low horizontal permeability, and concentrated the seepage flow towards more permeable zones on the flanks of the swale. This resulted in the formation of sand boils at the base of the levee. Both geomorphic features at Francis and Rena Lara were identified as surface drainages using remote sensing data. With the assistance of borehole and elevation data, geophysics was successfully used to characterize the features at each site. Properties such as permeability and clay content were derived from responses in electrical conductivity and used to build seepage models at each site. These models will hopefully be considered when determining seepage conditions and mitigation techniques at other sites along the levee.

  16. Nonequilibrium Stagnation-Line Radiative Heating for Fire II

    Johnston, Christopher O.; Hollis, Brian R.; Sutton, Kenneth

    2007-01-01

    This paper presents a detailed analysis of the shock-layer radiative heating to the Fire II vehicle using a new air radiation model and a viscous shock-layer flowfield model. This new air radiation model contains the most up-to-date properties for modeling the atomic-line, atomic photoionization, molecular band, and non-Boltzmann processes. The applied viscous shock-layer flowfield analysis contains the same thermophysical properties and nonequilibrium models as the LAURA Navier-Stokes code. Radiation-flowfield coupling, or radiation cooling, is accounted for in detail in this study. It is shown to reduce the radiative heating by about 30% for the peak radiative heating points, while reducing the convective heating only slightly. A detailed review of past Fire II radiative heating studies is presented. It is observed that the scatter in the radiation predicted by these past studies is mostly a result of the different flowfield chemistry models and the treatment of the electronic state populations. The present predictions provide, on average throughout the trajectory, a better comparison with Fire II flight data than any previous study. The magnitude of the vacuum ultraviolet (VUV) contribution to the radiative flux is estimated from the calorimeter measurements. This is achieved using the radiometer measurements and the predicted convective heating. The VUV radiation predicted by the present model agrees well with the VUV contribution inferred from the Fire II calorimeter measurement, although only when radiation-flowfield coupling is accounted for. This agreement provides evidence that the present model accurately models the VUV radiation, which is shown to contribute significantly to the Fire II radiative heating.

    2013-07-01

    This 3-year project was terminated at the end of Year 1 because the DOE Geothermal project-evaluation committee decided one Milestone was not met and also concluded that our technology would not be successful. The Review Panel recommended a ?no-go? decision be implemented by DOE. The Principal Investigator and his research team disagreed with the conclusions reached by the DOE evaluation committee and wrote a scientifically based rebuttal to the erroneous claims made by the evaluators. We were not told if our arguments were presented to the people who evaluated our work and made the ?no-go? decision. Whatever the case regarding the information we supplied in rebuttal, we received an official letter from Laura Merrick, Contracting Officer at the Golden Field Office, dated June 11, 2013 in which we were informed that project funding would cease and instructed us to prepare a final report before September 5, 2013. In spite of the rebuttal arguments we presented to DOE, this official letter repeated the conclusions of the Review Panel that we had already proven to be incorrect. This is the final report that we are expected to deliver. The theme of this report will be another rebuttal of the technical deficiencies claimed by the DOE Geothermal Review Panel about the value and accomplishments of the work we did in Phase 1 of the project. The material in this report will present images made from direct-S modes produced by vertical-force sources using the software and research findings we developed in Phase 1 that the DOE Review Panel said would not be successful. We made these images in great haste when we were informed that DOE Geothermal rejected our rebuttal arguments and still regarded our technical work to be substandard. We thought it was more important to respond quickly rather than to take additional time to create better quality images than what we present in this Final Report.

    2003-03-01

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) sponsored a May 2002 workshop on gene-environment interaction (G x E) research to identify potential roadblocks to further research and to propose solutions to those roadblocks, to optimize investigative opportunities and multidisciplinary or multi-institution collaborations, and to explore ways that NIAAA can facilitate G x E studies. Sessions included panels on animal models; phenotypes; genetic findings in humans; study designs and analytical methods; and assessment of environmental risk. Key among the identified challenges to progress in G x E research were issues of study design and sampling strategies; logistic and methodological costs and constraints; availability and understanding of data analysis techniques; potential stigmatization of study populations; and organizational/bureaucratic structures that are inadequate to address the unique needs of large-scale, multicenter, longitudinal projects. Participants proposed a series of recommendations to address these issues. Session coordinators included: Gayle Boyd, Kendall Bryant, Page Chiapella, Vivian Faden, David Goldman, and Antonio Noronha. Session participants included: Laura Almasy, Henri Begleiter, Raul Caetano, Bruce Dudek, Mary Dufour, Cindy Ehlers, Mary-Anne Enoch, Joel Gelernter, David Goldman, Bridget Grant, Lorraine Gunzerath, Deborah Hasin, Andrew Heath, Victor Hesselbrock, J.

    Hemodynamic imaging results have associated both gender and body weight to variation in brain responses to food-related information. However, the spatio-temporal brain dynamics of gender-related and weight-wise modulations in food discrimination still remain to be elucidated. We analyzed visual evoked potentials (VEPs) while normal-weighted men (n = 12) and women (n = 12) categorized photographs of energy-dense foods and non-food kitchen utensils. VEP analyses showed that food categorization is influenced by gender as early as 170 ms after image onset. Moreover, the female VEP pattern to food categorization co-varied with participants' body weight. Estimations of the neural generator activity over the time interval of VEP modulations (i.e. by means of a distributed linear inverse solution [LAURA]) revealed alterations in prefrontal and temporo-parietal source activity as a function of image category and participants' gender. However, only neural source activity for female responses during food viewing was negatively correlated with body-mass index (BMI) over the respective time interval. Women showed decreased neural source activity particularly in ventral prefrontal brain regions when viewing food, but not non-food objects, while no such associations were apparent in male responses to food and non-food viewing. Our study thus indicates that gender influences are already apparent during initial stages of food-related object categorization, with small variations in body weight modulating electrophysiological responses especially in women and in brain areas implicated in food reward valuation and intake control. These findings extend recent reports on prefrontal reward and control circuit responsiveness to food cues and the potential role of this reactivity pattern in the susceptibility to weight gain.

    The fourth volume of GERBERTVS contains the acts of the symposia held in Rome, at the Odeion hall of Lettere faculty in Sapienza University on December 7, 2012 Gerbert Homo Novus and on March 13, 2013 on the pre and post humanistic figures. Laura C. Paladino presents the didactical activity of Gerbert as from Richer of Reims who completed his Historia Francorum in 998, before the election of Gerbert to the pontifical soil. Among these activities there is the teaching of astronomy and mathematics and the abacus, to which a special article of Jorge Nuno Silva is dedicated. The abacus increased dramatically the rapidity of the computations and some algoritms thaught by Gerbert and reported by his former student Bernelinus is very reliably invented by Gerbert himself, as Silva demostrates in his paper. Giancarlo Pani presents the relation between Galileo and Kepler, at the end of the humanistic period, showing interesting insights on the rather asymmetrical exchange of information between the two greater astronomer of 1600. Veronica Regoli presents the Cosmos of Dante, the ideal structure of the Divine Comedy. Patrick Demouy presents the new biography of Flavio G. Nuvolone where the great novelty is the noble origin of Gerbert from Carlat family, but before the marriage of his (presumed) father. His birth is shifted back to 938 with technical demostrations. Paolo Zanna compares the magisterium of Gerbert-Sylvester II and that one of John Paul II and pope Francesco. Finally C. Sigismondi presents the work and the activities of Pawel Max Maksym (1983-2013) who founded the Observatory &"Pope Sylvester II" in the town of Bukowiec, near Lodz, Poland.

    Multiverse at the University of California, Berkeley Space Sciences Laboratory provides earth and space science educational opportunities and resources for a variety of audiences, especially for those who are underrepresented in the sciences. By way of carefully crafted space and earth science educational opportunities and resources, we seek to connect with people's sense of wonder and facilitate making personal ties to science and the learning process in order to, ultimately, bring the richness of diversity to science and make science discovery accessible for all. Our audiences include teachers, students, education and outreach professionals, and the public. We partner with NASA, the National Science Foundation, scientists, teachers, science center and museum educators, park interpreters, and others with expertise in reaching particular audiences. With these partners, we develop resources and communities of practice, offer educator workshops, and run events for the public. We will will present on our pedagogical techniques, our metrics for success, and our evaluation findings of our education and outreach projects that help us towards reaching our vision: We envision a world filled with science literate societies capable of thriving with today's technology, while maintaining a sustainable balance with the natural world; a world where people develop and sustain the ability to think critically using observation and evidence and participate authentically in scientific endeavors; a world where people see themselves and their culture within the scientific enterprise, and understand science within the context that we are all under one sky and on one Earth.

    The Kootenai River Network Inc. (KRN) was incorporated in Montana in early 1995 with a mission ''to involve stakeholders in the protection and restoration of the chemical, physical and biological integrity of the Kootenai River Basin waters''. The KRN operates with funding from donations, membership dues, private, state and federal grants, and with funding through the Bonneville Power Administration (BPA) for a Focus Watershed Coordinator Program. The Focus Watershed Program is administered to KRN as of October 2001, through a Memorandum of Understanding. Katie Randall resigned her position as Watershed Coordinator in late January 2003 and Munson Consulting was contracted to fill that position through the BPA contract period ending May 30, 2003. To improve communications with in the Kootenai River watershed, the board and staff engaged watershed stakeholders in a full day KRN watershed conference on May 15 and 16 in Bonners Ferry, Idaho. This Annual General Meeting was a tremendous success with over 75 participants representing over 40 citizen groups, tribes and state/provincial/federal agencies from throughout northern Montana and Idaho as well as British Columbia and Alberta. Membership in the KRN increased during the course of the BPA 02/03 grant period. The board of directors grew in numbers during this same time frame and an Advisory Council was formed to assist in transboundary efforts while developing two reorganized KRN committees (Habitat/Restoration/Monitoring (HRM) and Communication/Education/Outreach (CEO)). These committees will serve pivotal roles in communications, outreach, and education about watershed issues, as well as habitat restoration work being accomplished throughout the entire watershed. During this BPA grant period, the KRN has capitalized on the transboundary interest in the Kootenai River watershed. Jim and Laura Duncan of Kimberley, British Columbia, have been instrumental volunteers who have acted as Canadian liaisons to the KRN. As a

    This volume contains the invited and contributed papers presented at the 14th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 29-31 October, 2013. The meeting was held at the Palazzone, an elegant Renaissance Villa, commissioned by the Cardinal Silvio Passerini (1469-1529), Bishop of Cortona, and presently owned by the Scuola Normale Superiore di Pisa. The aim of this biennial Conference is to bring together Italian theorists working in various fields of nuclear physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to stimulate new ideas and promote collaborations between different research groups. The Conference was attended by 46 participants, coming from 13 Italian Universities and 11 Laboratories and Sezioni of the Istituto Nazionale di Fisica Nucleare - INFN. The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on the following main topics: Few-Nucleon Systems Nuclear Structure Nuclear Matter and Nuclear Dynamics Relativistic Heavy Ion Collisions and Quark-Gluon Plasma Nuclear Astrophysics Nuclear Physics with Electroweak Probes Structure of Hadrons and Hadronic Matter. In the last session of the Conference there were two invited review talks related to experimental activities of great current interest. Giacomo De Angelis from the Laboratori Nazionali di Legnaro spoke about the INFN SPES radioactive ion beam project. Sara Pirrone, INFN Sezione di Catania, gave a talk on the symmetry energy and isospin physics with the CHIMERA detector. Finally, Mauro Taiuti (Università di Genova), National Coordinator of the INFN-CSN3 (Nuclear Physics Experiments), reported on the present status and future challenges of experimental nuclear physics in Italy. We gratefully acknowledge the financial support of INFN who helped make the conference possible. I Bombaci, A Covello

  8. Intrinsic Uncertainties in Modeling Complex Systems.

    2014-09-01

    Models are built to understand and predict the behaviors of both natural and artificial systems. Because it is always necessary to abstract away aspects of any non-trivial system being modeled, we know models can potentially leave out important, even critical elements. This reality of the modeling enterprise forces us to consider the prospective impacts of those effects completely left out of a model - either intentionally or unconsidered. Insensitivity to new structure is an indication of diminishing returns. In this work, we represent a hypothetical unknown effect on a validated model as a finite perturba- tion whose amplitude is constrained within a control region. We find robustly that without further constraints, no meaningful bounds can be placed on the amplitude of a perturbation outside of the control region. Thus, forecasting into unsampled regions is a very risky proposition. We also present inherent difficulties with proper time discretization of models and representing in- herently discrete quantities. We point out potentially worrisome uncertainties, arising from math- ematical formulation alone, which modelers can inadvertently introduce into models of complex systems.

    For over thirty years the College of Charleston has been teaching a year-long introductory astronomy course incorporating a mandatory 3 hour lab. Despite our location in a very light polluted, coastal, high humidity, and often cloudy metropolitan area we have emphasized observational activities as much as possible. To accommodate our population of between 300-400 students per semester, we have 28 8-inch Celestron Telescopes and 25 GPS capable 8-inch Meade LX-200 telescopes. Finally, we have a 16 DFM adjacent to our rooftop observing decks. For indoor activities we have access to 42 computers running a variety of astronomy education software. Some of the computer activities are based on the Starry Night software (Backyard and Pro), the CLEA software from Gettysburg College, and Spectrum Explorer from Boston University. Additionally, we have labs involving cratering, eclipses and phases, coordinate systems with celestial globes, the inverse square law, spectroscopy and spectral classification, as well as others. In this presentation we will discuss the difficulties in managing a program of this size. We have approximately 14 lab sections a week. The lab manager's task involves coordinating 8-10 lab instructors and the same number of undergraduate teaching assistants as well as trying to maintain a coherent experience between the labs and lecture sections. Our lab manuals are produced locally with yearly updates. Samples from the manuals will be available. This program has been developed by a large number of College of Charleston astronomy faculty, including Don Drost, Bob Dukes, Chris Fragile, Tim Giblin, Jon Hakkila, Bill Kubinec, Lee Lindner, Jim Neff, Laura Penny, Al Rainis, Terry Richardson, and D. J. Williams, as well as adjunct and visiting faculty Bill Baird, Kevin Bourque, Ethan Denault, Kwayera Davis, Francie Halter, and Alan Johnson. Part of this work has been funded by NSF DUE grants to the College of Charleston.

    A ballute (balloon-parachute) is an inflatable, aerodynamic drag device for application to planetary entry vehicles. Two challenging aspects of aerothermal simulation of towed ballutes are considered. The first challenge, simulation of a complete system including inflatable tethers and a trailing toroidal ballute, is addressed using the unstructured-grid, Navier-Stokes solver FUN3D. Auxiliary simulations of a semi-infinite cylinder using the rarefied flow, Direct Simulation Monte Carlo solver, DSV2, provide additional insight into limiting behavior of the aerothermal environment around tethers directly exposed to the free stream. Simulations reveal pressures higher than stagnation and corresponding large heating rates on the tether as it emerges from the spacecraft base flow and passes through the spacecraft bow shock. The footprint of the tether shock on the toroidal ballute is also subject to heating amplification. Design options to accommodate or reduce these environments are discussed. The second challenge addresses time-accurate simulation to detect the onset of unsteady flow interactions as a function of geometry and Reynolds number. Video of unsteady interactions measured in the Langley Aerothermodynamic Laboratory 20-Inch Mach 6 Air Tunnel and CFD simulations using the structured grid, Navier-Stokes solver LAURA are compared for flow over a rigid spacecraft-sting-toroid system. The experimental data provides qualitative information on the amplitude and onset of unsteady motion which is captured in the numerical simulations. The presence of severe unsteady fluid - structure interactions is undesirable and numerical simulation must be able to predict the onset of such motion.

  11. Strategies for coping with labour: does antenatal education translate into practice?

    There is little evidence to associate attendance at antenatal classes with a reduction in psychological distress or increased satisfaction with the experience of labour. There may be several reasons for this, including failure to implement coping strategies. A within-subjects research design explored the use in labour of coping strategies taught in antenatal classes and the role of practice. Women's views about using these strategies and their expectations of their midwives and birth companions were also identified. Following Ethics Committee approval and providing informed consent, 121 nulliparous women completed a questionnaire at their final antenatal class. This included questions on confidence and the amount of effort required to use coping strategies, the involvement hoped for from birth companions and midwives in using coping strategies in labour and satisfaction with the amount of practice of coping strategies. Within 72 hours of delivery, women were interviewed to obtain a narrative of the events of labour and their use of the coping strategies (sighing-out-slowly breathing, Laura Mitchell relaxation and postural change). A questionnaire obtained information on the involvement of the midwife and birth companion. Women used the three coping strategies to different extents. Midwives were not involved to the extent that women had hoped for antenatally. Birth companions achieved a level of involvement closer to women's hopes than that achieved by midwives. A significant proportion of women expressed dissatisfaction with the amount of practice of coping strategies during antenatal classes. The findings of this study of a group of well-prepared women raise questions about the correct components of antenatal classes and how midwives and birth companions can be involved optimally in this aspect of a woman's labour. Further research is required to determine how women can best be helped to cope with the experience of labour.

    2014-01-01

    NEQAIR v14.0 is the first parallelized version of NEQAIR. Starting from the last version of the code that went through the internal software release process at NASA Ames (NEQAIR 2008), there have been significant updates to the physics in the code and the computational efficiency. NEQAIR v14.0 supersedes NEQAIR v13.2, v13.1 and the suite of NEQAIR2009 versions. These updates have predominantly been performed by Brett Cruden and Aaron Brandis from ERC Inc at NASA Ames Research Center in 2013 and 2014. A new naming convention is being adopted with this current release. The current and future versions of the code will be named NEQAIR vY.X. The Y will refer to a major release increment. Minor revisions and update releases will involve incrementing X. This is to keep NEQAIR more in line with common software release practices. NEQAIR v14.0 is a standalone software tool for line-by-line spectral computation of radiative intensities and/or radiative heat flux, with one-dimensional transport of radiation. In order to accomplish this, NEQAIR v14.0, as in previous versions, requires the specification of distances (in cm), temperatures (in K) and number densities (in parts/cc) of constituent species along lines of sight. Therefore, it is assumed that flow quantities have been extracted from flow fields computed using other tools, such as CFD codes like DPLR or LAURA, and that lines of sight have been constructed and written out in the format required by NEQAIR v14.0. There are two principal modes for running NEQAIR v14.0. In the first mode NEQAIR v14.0 is used as a tool for creating synthetic spectra of any desired resolution (including convolution with a specified instrument/slit function). The first mode is typically exercised in simulating/interpreting spectroscopic measurements of different sources (e.g. shock tube data, plasma torches, etc.). In the second mode, NEQAIR v14.0 is used as a radiative heat flux prediction tool for flight projects. Correspondingly, NEQAIR has

    The Kootenai River Network (KRN) was contracted by the Bonneville Power Administration; PPA Project Number 96087200 for the period June 1, 2004 to May 31, 2005 to provide Kootenai River basin watershed coordination services. The prime focus of the KRN Watershed Coordination Program is coordinating projects and disseminating information related to watershed improvement and education and outreach with other interest groups in the Kootenai River basin. The KRN willingly shares its resources with these groups. The 2004-2005 BPA contract extended the original Montana Fish, Wildlife and Parks contract, which was transferred to the Kootenai River Network through a Memorandum of Understanding in November 2001. The KRN objectives of this contract were carried out by one half-time Watershed Coordinator position in Montana-Idaho (Nancy Zapotocki) and one half-time Watershed Coordination team in British Columbia (Laura and Jim Duncan). Nancy Zapotocki was hired as the KRN US Watershed Coordinator in July 2004. Her extensive work experience in outreach and education and watershed planning complements the Duncans in British Columbia. To continue rejuvenating and revitalizing the KRN, the Board conducted a second retreat in November 2004. The first retreat took place in November 2003. Board and staff members combined efforts to define KRN goals and ways of achieving them. An Education and Outreach Plan formulated by the Watershed Coordinators was used to guide much of the discussions. The conclusions reached during the retreat specified four ''flagship'' projects for 2005-2006, to: (1) Provide leadership and facilitation, and build on current work related to the TMDL plans and planning efforts on the United States side of the border. (2) Continue facilitating trans-boundary British Columbia projects building on established work and applying the KRN model of project facilitation to other areas of the Kootenai basin. (3) Finalize and implement the KRN Education and Outreach plan

This scenario exposes a learning unit based on experimental sequences (defining specific competencies), as a succession of lessons started by noticing a problem whose solution assumes the setup of an experiment under laboratory conditions. Progressive learning of theme objectives are realised with sequential experimental steps. The central cognitive process is the induction or the generalization (development of new knowledge based on observation of examples or counterexamples of the concept to be learnt). Pupil interest in theme objectives is triggered by problem-situations, for example: "In order to better see small objects I need a magnifying glass. But when using a magnifier, small object images are sometimes seen upright and sometimes seen reversed!" Along the way, pupils' reasoning will converge to the idea: "The image of an object through a lens depends on the relative distances among object, lens, and observer".

    2007-09-14

    In an editorial earlier this year (JAAS, 22, 111, 2007), we opined that metallomics, the study of metals in biological systems, would be an increasingly important topic in elemental analysis in general and for this journal in particular . This issue of the journal, co-edited by the two of us, is a second special issue covering the subject of Metallomics (the first issue was JAAS, 19/1, 2004). The present issue is comprised of technique, application, and perspective papers that address this emerging field of study and show how atomic spectrometry is contributing to the understanding of biological systems. The subjects covered range from metal binding in plants through investigations of metal and metalloids in samples of biological fluids to the study of food supplements and drug interactions in cells. The issue includes two Critical Reviews. Yuxi Gao and colleagues discuss advanced nuclear analytical techniques for the emerging field of metalloproteomics. While Laura Liermann and her colleagues consider how micro-organisms extract metals from minerals in the environment for utilization in metabolic processes. The content of some of these papers stretches the traditional boundaries and scope of this journal, as echoed by the reviewers of some of the papers. This discussion about scope requires perhaps further debate. However, it is our view that while the Journal must remain true to its core aims, it must also strive to accommodate and motivate a wider authorship and readership. Metallomics is a field that transcends biology and microbiology, biochemistry, clinical chemistry, environmental chemistry, geochemistry, and yes, atomic spectroscopy. If JAAS aspires to be a leading force in metallomics, the Journal must expand its horizons beyond traditional analytical spectroscopy per se. Accordingly, in this special issue you will find papers that have a heavy clinical emphasis, which speak to complementary (non-atomic) spectroscopic techniques, and that provide

Mixed infections can significantly contribute to the uncertainty in host-pathogen dynamics with direct implications for host demographics, disease management strategies, and evolution of virulence. The results of this study indicate a widespread presence of multiple-genotype malaria infections with high clonal diversity in native birds of Hawaii, which when coupled with concurrent infection with Avipoxvirus, may significantly influence evolution of virulence.

    Munski, Laura

    Following the flood of 1997, the U.S. Army Corps of Engineers included the Greenway Grand Forks---East Grand Forks (the Greenway) as a flood control measure for Grand Forks, North Dakota and East Grand Forks, Minnesota. It extends along both the Red River of the North and the Red Lake River, encompassing 2200 acres of land. The cities of Grand Forks and East Grand Forks hired consultants to assist with the postflood planning process. The planning process culminated with the Red River of the North Greenway Final Report (Flink, 1998). The purpose of this study was to determine if the development of the Greenway addressed the objectives of the planning report. The history of the land adjacent to the rivers was reviewed to document the progression of riverfront development. Anecdotal evidence was collected, field observations were made, city council minutes were reviewed, Greenway Technical Committee members were interviewed, Greenway Technical Committee minutes were reviewed, and the Greenway Grand Forks---East Grand Forks survey results were reviewed to determine if the objectives of the Red River of the North Greenway Final Report were addressed. A cross section survey was designed by Laura Munski for this dissertation research. The survey was approved by the Greenway Technical Committee. The survey collected both quantitative and qualitative data from the community. The purpose of the survey portion of the research project was to ascertain how residents were kept informed of activities on the Greenway and what amenities residents were using on the Greenway and to solicit their comments regarding the Greenway. The results of the survey research were used in both marketing and event planning for the Greenway. The singular qualitative survey question gave respondents an opportunity to share their comments regarding the Greenway. The qualitative data analysis provided insight to the amenities and educational programs desired by respondents, their concerns regarding the

    2016-04-01

    Born from a desire to promote the Italian landscape by integrating its physical aesthetic with its cultural and artistic heritage, we develop a story about the landscape told in popular science, and supported by visual stimulations, poetry and ancient music. Our work proceeds through two different routes. The first route analyzes the landscape from the scientific point of view trying to understand how it evolves and responds in response to changes in independent variables. The second path examines the landscape from a perspective more closely related to the visual and emotional impact that a place evokes, its history, its cultural significance, and perception of its fragility. The latter is perhaps a more complex path, more intimate, which develop fully only through the intersection of different forms of language, linked to specific arts. Three different disciplines focused on the same site, the combination of which results in an emotional experience where the encounter between different languages becomes an expression of the place. Among the many amazing landscapes of Italy, we focus on three known sites from the hystorical region of Montefeltro, in central Italy: "The flatiron of Petrano Mount", "The Stones of Montefeltro", "The sea-cliff of San Bartolo". Since a few years we have created a team of five researchers-artists, called "TerreRare" (Rare Earth Elements), whose mission is the desire to promote the gorgeous Italian landscape. Olivia Nesci, geomorphologist, begins this story analyzing the processes and the "forces" that have created and modified the landscape over time. Laura Valentini, a geologist and a musician, through the musical language, try to reproduce the emotional impact of the site, by searching for a piece of ancient music, composed for harpsichord. The choice of the musical instrument and the historical period is not accidental: the harpsichord has a punchy and gritty tone that clearly expresses the "strength" of the landscape; early music

    An important achievement in hydraulic engineering is the proposal and development of new techniques for the measurement of field velocities in hydraulic problems. The technological advances in digital cameras with high resolution and high speed found in the market, and the advances in digital image processing techniques now provides a tremendous potential to measure and study the behavior of the water surface flows. This technique was applied at the Laboratory of Hydraulics at the Technical University of Catalonia - Barcelona Tech to study the 2D velocity fields in the vicinity of a grate inlet. We used a platform to test grate inlets capacity with dimensions of 5.5 m long and 4 m wide allowing a zone of useful study of 5.5m x 3m, where the width is similar of the urban road lane. The platform allows you to modify the longitudinal slopes from 0% to 10% and transversal slope from 0% to 4%. Flow rates can arrive to 200 l/s. In addition a high resolution camera with 1280 x 1024 pixels resolution with maximum speed of 488 frames per second was used. A novel technique using particle image velocimetry to measure surface flow velocities has been developed and validated with the experimental data from the grate inlets capacity. In this case, the proposed methodology can become a useful tools to understand the velocity fields of the flow approaching the inlet where the traditional measuring equipment have serious problems and limitations.

    Review of COSPAR Mars Special Regions Parameter Definition Charles S. Cockell (??), Ger-hard Kminek (??), Amedea Perfumo (??), Laura Kelly (??) 1. Planetary and Space Sciences Research Institute, Open University, CityplaceMilton Keynes, country-regionU.K. 2. ESA-ESTEC, Keplerlaan 1, 2200 Noordwijk, Netherlands. A Mars special region is a `region within which terrestrial organisms are likely to propagate, or a region which is interpreted to have a high potential for the existence of extant martian life forms'. We are undertaking a review of the parameter space that defines a special region. We agree, consistent with the COSPAR Mars Special Regions Colloquium held in Rome in 2007, that any region experiencing temperatures > -25°C for a few hours a year and a water activity > 0.5 can potentially allow the replication of terrestrial microorganisms. However, with respect to the role of salts in defining a special region, recent research shows that water activity per se may not be the limiting factor for life in extremely arid environments (??). Chaotropic salts (those which have a tendency to destabilize macromolecules), such as MgCl2 and CaCl2, may exert a more important influence on the survival of microorganisms in very arid environments. Given the unlikelihood of high concentrations of kosmotropic (stabilizing) substances, such as sugars, many Martian environments, particularly ancient sedimentary deposits, may turn out to be places where chaotropic characteristics of salts will be a more important factor for biological macromolecules than water activity, although water activity still remains an important metric in defining biological activity. Even with the presence of transient liquid water, chaotropic salts may still act to limit the growth and reproduction of life. Chaotropism needs to be assessed for a range of new salts in relation to different microorganisms and in relation to the predicted salt composition of Martian surface (including evaporitic

    Perry, John, Lowenstern, Jacob, Cervelli, Peter, Clor, Laura, Heasler, Henry, Allen, Scott, Moloney, Tim During June 2010, ten 900MHz wireless temperature data loggers (nodes) were installed around the Norris Geyser Basin to monitor geothermal features, streams and soil temperatures. The loggers can provide near real-time updates on temperature variations within 0.2 deg C due to hydrothermal discharges or subsurface fluid migration. Each sensor node is programmed to measure the temperature every two minutes and automatically upload data to the base station computer daily. The hardware consists of a waterproof case containing an M5 logger (made by Marathon Products, Inc.®) with internal memory, lithium D-cell batteries and a 900 MHz, 1-W-transceiver and 5 meter long Teflon-coated probe with a thermistor sensor. Tethered stub or panel antennas are oriented to optimize signal strength to the base station near the Norris Museum. A 0.61 meter-long base-station antenna located 10m high provides signal to the furthest node over 850 meters away with most being “line-of-sight”. A 20-meter coaxial cable and lightning grounding wire connects the base-station antenna to an Ethernet-radio connected to the YNP local-area network. A server located 26-km north at Mammoth Hot Springs requests data at regular intervals (normally daily), archives the information, and then sends it to the USGS for further archiving and internet distribution. During periods of unusual hydrothermal behavior, data can be requested as needed, and it is possible to set user-programmable alarm limits for notification. The RF network is designed to monitor changes from three different sub-basins at Norris (Gray Lakes, Steamboat-Echinus and Porcelain Basin), the main Tantalus Creek drainage, and five individual thermal features (Constant, Porkchop, Steamboat and Echinus Geysers, and Opalescent Spring). The logger installed in Nuphar Lake provides ambient temperatures controlled solely by local

    Recent neuroimaging research suggests that human sexual desire (SD) recruits both the limbic system and higher-order cognitive brain areas. Because of the temporal limitation of this technique, the chronoarchitecture of SD remains however unresolved. Here, we investigated the spatio-temporal dynamics of SD by combining a behavioral desire decision task with high-density visual event-related potential (VEP) recordings and brain source estimations. VEPs were recorded from thirteen healthy participants when presented with pictures from two different stimulus categories (i.e., high and low desirability). In agreement with the literature, behavioral results showed that participants were faster to rate non-desired stimuli than desired stimuli (p=0.028). Electrophysiological results extended these behavioral data. Group-averaged VEPs peaked at 90 to 140 ms (P100), at 142 to 220 ms (N200), and at 222 to 360 ms (P300). Desired stimuli (DS) were distinguished from non-desired stimuli (NDS) over the N200 period, notably from 142 to 187 ms. Over this time period, DS processing was characterized by a significant scalp potential field. Although both conditions (DS and NDS) showed the recruitment of the occipito-temporal region (including the extrastriate body area, EBA), LAURA source estimation of the DS scalp potential field revealed a more right-lateralized current source density maximum in the posterior superior temporal sulcus (STS) extending to the temporo-parietal junction (TPJ). The recruitment of STS and TPJ for desired stimuli indicates that these brain areas, known to be respectively involved in social cognition, attention, integration of body-related information and self-processing, play a crucial role for the coding of desirability of visual sexual human stimuli within the first 200 ms after stimulus onset. These findings support the hypothesis that complex cognitive processing for desire occurs much faster than previously thought and open new perspectives with

    2003-01-01

    This report summarizes activities carried out with support from the NASA Ultraviolet, Visible, and Gravitational Astrophysics Research and Analysis Program under Grant NAG 5-6821. The Principal Investigator is Howard E. Bond (Space Telescope Science Institute). STScI Postdoctoral Associates Laura K. Fullton (1998), David Alves (1998-2001), and Michael Siegel (2001) were partially supported by this grant. The aim of the program is to calibrate the absolute magnitudes of post-asymptotic- giant-branch (post-AGB or PAGB) stars, which we believe will be an excellent new "standard candle" for measuring extragalactic distances. The argument is that, in old populations, the stars that are evolving through the PAGB region of the HR diagram arise from only a single main-sequence turnoff mass. In addition, theoretical PAGB evolutionary tracks show that they evolve through this region at constant luminosity; hence the PAGB stars should have an extremely narrow luminosity function. Moreover, as the PAGB stars evolve through spectral types F and A (en route from the AGB to hot stellar remnants and white dwarfs), they have the highest luminosities attained by old stars (both bolometrically and in the visual band). Finally, PAGB stars of these spectral types are very easily identified. because of their large Balmer jumps, which are due to their very low surface gravities. Our approach is first to identify PAGB stars in Milky Way globular clusters and in other Local Group galaxies, which are at known distances, and thus to measure accurate absolute magnitudes for the PAGB stars. With this Milky Way and Local Group luminosity calibration, we will then be in a position to find PAGB stars in more distant galaxies from the ground, and ultimately from the Hubble Space Telescope. and thus derive distances. These PAGB stars are, as noted above, the visually brightest members of Population II, and hence will allow distance measurements to galaxies that do not contain Cepheids, such as

  18. Transitions from high school to college.

    Venezia, Andrea; Jaeger, Laura

    2013-01-01

    The vast majority of high school students aspire to some kind of postsecondary education, yet far too many of them enter college without the basic content knowledge, skills, or habits of mind they need to succeed. Andrea Venezia and Laura Jaeger look at the state of college readiness among high school students, the effectiveness of programs in place to help them transition to college, and efforts to improve those transitions. Students are unprepared for postsecondary coursework for many reasons, the authors write, including differences between what high schools teach and what colleges expect, as well as large disparities between the instruction offered by high schools with high concentrations of students in poverty and that offered by high schools with more advantaged students. The authors also note the importance of noncurricular variables, such as peer influences, parental expectations, and conditions that encourage academic study. Interventions to improve college readiness offer a variety of services, from academic preparation and information about college and financial aid, to psychosocial and behavioral supports, to the development of habits of mind including organizational skills, anticipation, persistence, and resiliency. The authors also discuss more systemic programs, such as Middle College High Schools, and review efforts to allow high school students to take college classes (known as dual enrollment). Evaluations of the effectiveness of these efforts are limited, but the authors report that studies of precollege support programs generally show small impacts, while the more systemic programs show mixed results. Dual-enrollment programs show promise, but the evaluation designs may overstate the results. The Common Core State Standards, a voluntary set of goals and expectations in English and math adopted by most states, offer the potential to improve college and career readiness, the authors write. But that potential will be realized, they add, only if the

    2009-07-01

    These Proceedings contain the invited and contributed papers presented at the 12th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 8-10 October 2008. As usual, the meeting was held at il Palazzone, a 16th century castle owned by the Scuola Normale Superiore di Pisa. The aim of this biennal conference is to bring together Italian theorists working in various fields of Nuclear Physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to promote collaborations between different groups. There were about 50 participants at the conference, coming from 14 Italian Universities (Cagliari, Catania, Ferrara, Firenze, Genova, Lecce, Milano, Napoli, Padova, Pavia, Pisa, Roma, Trento, Trieste). The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on six main topics: Few-Nucleon Systems, Nuclear Matter and Nuclear Dynamics, Nuclear Astrophysics, Structure of Hadrons and Hadronic Matter, Nuclear Structure, Nuclear Physics with Electroweak Probes. Winfried Leidemann, Maria Colonna, Marcello Lissia, Elena Santopinto, Silvia Lenzi and Omar Benhar took the burden of giving general talks on these topics and reviewing the research activities of the various Italian groups. In addition, 19 contributed papers were presented, most of them by young participants. In the last session of the Conference there were two invited talks related to experimental activities of great current interest. Gianfranco Prete from the Laboratori Nazionali di Legnaro spoke about the Italian radioactive ion beam facility SPES and the status of the European project EURISOL, while Nicola Colonna from the INFN, Bari, gave an overview of the perspectives of development of fourth-generation nuclear reactors. We would like to thank the authors of the general reports for their hard work in reviewing the main achievements in

In the article, a raw data merging error in one racial discrimination claim condition from Experiment 6 inadvertently resulted in data analyses on an inaccurate data set. When the error was discovered by the authors and corrected, all analyses reported in Experiment 6 for claim validity, seriousness of the claim, and support for the claimant were inaccurate and none were statistically significant. The conclusions should be altered to indicate that participants with management experience who reflected on their own workplace diversity policies did not show the predicted effects. The literature review, remaining five studies, and remaining conclusions in the article are unaffected by this error. Experiment 6 should also report that 26.4% (not 26.4.7%) of participants had a graduate degree and eight participants (not 8%) did not provide educational data. Experiment 5 should have referred to the claim validity measure as a six-item measure ( .92) rather than a five-item measure; analyses on claim validity are accurate in text. Table 2's note should have said standard errors, not standard deviations. (The following abstract of the original article appeared in record 2012-31077-001.) This research tests the hypothesis that the presence (vs. absence) of organizational diversity structures causes high-status group members (Whites, men) to perceive organizations with diversity structures as procedurally fairer environments for underrepresented groups (racial minorities, women), even when it is clear that underrepresented groups have been unfairly disadvantaged within these organizations. Furthermore, this illusory sense of fairness derived from the mere presence of diversity structures causes high

    The Laura-Normanby River (catchment area: 24,350 km(2)), which drains into Princess Charlotte Bay, has been identified in previous studies as the third largest contributor of sediment to the Great Barrier Reef World Heritage Area. These catchment scale modelling studies also identified surface soil erosion as supplying >80% of the sediment. Here we use activity concentrations of the fallout radionuclides (137)Cs and (210)Pbex to test the hypothesis that surface soil erosion dominates the supply of fine (<10 μm) sediment in the river systems draining into Princess Charlotte Bay. Our results contradict these previous studies, and are consistent with channel and gully erosion being the dominant source of fine sediment in this catchment. The hypothesis that surface soil erosion dominates the supply of fine sediment to Princess Charlotte Bay is rejected. River sediment samples were collected using both time-integrated samplers and sediment drape deposits. We show that there is no detectable difference in (137)Cs and (210)Pbex activity concentrations between samples collected using these two methods. Two methods were also used to collect samples to characterise (137)Cs and (210)Pbex concentrations in sediment derived from surface soil erosion; sampling of surface-wash deposits and deployment of surface runoff traps that collected samples during rain events. While there was no difference in the (137)Cs activity concentrations for samples collected using these two methods, (210)Pbex activity concentrations were significantly higher in the samples collected using the runoff traps. The higher (210)Pbex concentrations are shown to be correlated with loss-on-ignition (r(2) = 0.79) and therefore are likely to be related to higher organic concentrations in the runoff trap samples. As a result of these differences we use a three end member mixing model (channel/gully, hillslope surface-wash and hillslope runoff traps) to determine the relative contribution from surface soil

    This research grant supported an active sounding rocket program at Penn State University over a period of over 10 years. During this period, the grant supported at least 8 graduate students in Astronomy & Astrophysics for at least a portion of their research. During the same period, our group was involved in seven sounding rocket flights, launched from White Sands, New Mexico, and from Woomera, Australia. Most of these rocket flights, and most of the work supported by this grant, involved the use of X-ray CCD cameras. The first X-ray CCD camera ever flown in space was our sounding rocket observation of SN1987A (flight 36.030 in 1987). Subsequent flights utilized improved CCD detectors, culminating in the'state-of-the-art EEV detector developed for our CUBIC mission, which was flown on 36.093 last May. Data from the last three flights, which observed the diffuse X-ray background with CCDS, include detection of the OVII He(alpha) line in the high latitude diffuse background and detection of the Mg XI He(alpha) line in the North Polar Spur. These results have been reported at meetings of the American Astronomical Society and the SPIE. The analysis of flights 36.092 and 36.106 is part of Jeff Mendenhall's PhD thesis and will be published in the Astrophysical Journal next year. The 36.093 data are currently being analyzed by PhD student Laura Cawley. From 1990 to 1996 this grant supported our development and launch of the CUBIC instrument on the SAC-B satellite, which was designed to measure the spectrum of the soft X-ray diffuse background with moderate energy resolution and high S/N ratio. Unfortunately, this mission terminated shortly after launch due to a failure of the Pegasus XL launch vehicle. This work resulted in publication of 4 papers in the SPIE Proceedings and four others in refereed journals, in addition to several other conference proceedings and contributed papers. In addition to the CCD flights described above, this grant has supported preliminary

    On June 8, 2009, the U. S. Department of Energy's National Energy Technology Laboratory released a Funding Opportunity Announcement (DE-FOA 0000015) with the title, Recovery Act: Carbon Capture and Sequestration from Industrial Sources and Innovative Concepts for Beneficial CO{sub 2} Use. C6 Resources (C6), an affiliate of Shell Oil Company, responded with a proposal for Technology Area 1: Large-scale industrial carbon capture and sequestration (CCS) projects from industrial sources. As DOE Federally Funded Research and Development Center (FFRDC) Contractors, Lawrence Livermore National Laboratory (LBNL) and Lawrence Berkeley National Laboratory (LLNL) proposed to collaborate with C6 and perform technical tasks, which C6 included in the C6 proposal, titled the Northern California CO{sub 2} Reduction Project. The proposal was accepted for Phase I funding and C6 received DOE Award DEFE0002042. LLNL and LBNL each received Phase I funding of $200,000, directly from DOE. The essential task of Phase I was to prepare a proposal for Phase II, which would be a five-year, detailed technical proposal, budget, and schedule for a complete carbon capture, transportation, and geologic storage project, with the objective of starting the injection of 1 million tons per year of industrial CO2 by the end of FY2015. LLNL and LBNL developed technical proposals (and DOE Field Work Proposals [FWPs]) for many aspects of the geologic testing and CO{sub 2} monitoring that were included in the C6 Phase II proposal, which C6 submitted by the deadline of April 16, 2010. This document is the Final Report for LLNL's Phase I efforts and is presented in two parts. Part 1 is the complete text of the technical proposal provided to C6 by LLNL and LBNL for inclusion in the C6 Phase II proposal. Because of space limitations, however, C6 may not have included all of this information in their proposal.

    has been unaltered by human disturbance or practices. The aim of this study was to examine microbial community diversity associated with moonmilk deposits at Ballynamintra Cave, Ireland using automated ribosomal intergenic spacer analysis (ARISA). The results revealed considerable bacterial and fungal diversity associated with moonmilk in a karstic cave system, suggesting that the microbial community implicated in moonmilk formation may be more diverse than previously thought. These results suggest that microbes may have important functional roles in subterranean environments. Although the moonmilk in this study was largely comprised of calcite, microbial involvement in calcite precipitation could result in the bioavailability of a range of organic compounds for subsequent microbial metabolism.

    Vocabulary. These vocabularies and their mappings are an important part of the Eventlogger system. Before a research cruise investigators configure the instruments they intend to use for science activities. The instruments available for selection are pulled directly from the instrument vocabulary. The promotion and use of controlled vocabularies and ontologies will pave the way for linked data. By mapping local terms to agreed upon authoritative terms links are created, whereby related datasets can be discovered, and utilized. The Library is a natural home for the management of standards. Librarians have an established history of working with controlled vocabularies and metadata and libraries serve as centers for information discovery. Eventlogger is currently being tested across the UNOLS fleet. A large submission of suggested instrument terms to the SeaDataNet community listserv is in progress.

    Provost David L. Potter of George Mason University chaired a joint task force and presented a report entitled ``Powerful Partnerships : A Shared Responsibility for Learnin'' in June 1998. The main goal is to make a difference in the quality of student learning. Further, it is important to assess this difference and document it. Clifford O. Young, Sr., & Laura Howzell Young of California State University, San Bernardino argue that a new paradigm for assessment, a learning paradigm, must be constructed to measure the success of new kinds of educational practices. Using two survey instruments, the Instruction Model Learning Model Questionnaire (IMLMQ) and the Student Evaluation of Teaching Effectiveness (SETE), they compared students' responses to the course when taught with traditional methods and with interactive methods. The results suggest that neither instrument effectively measures the kinds of learning promoted under the new paradigm. Linn, Baker, & Dunbar recommend that these newer assessment practices should be more authentic, that is, to involve students in the actual or simulated performance of a task or the documentation of the desired competency in a portfolio. Cerbin says that one of the most unfortunate consequences of a summative emphasis is that it inhibits open and productive discussions about teaching; in essence, it marginalizes the types of activity that could lead to better teaching (Cerbin, 1992). William Cerbin, who is the Director of the Center for Effective Teaching and learning, University Assessment Coordinator, and Professor of Psychology at the University of Wisconsin-LaCrosse is a recognized expert in the areas of cognition, language, and development. Edgerton, Hutchings, & Quinlan indicate that Teaching Portfolios may contain evidence of students' learning, but such information is optional, and when included, it may be only one of many pieces of material. Seldin, also supports this and stresses that the interplay between the instructor

    Koteen, Laura E., Raz-Yaseef, Naama, and Dennis D. Baldocchi University of California, Berkeley California's blue oak, Quercus douglasii, is a unique tree in several ways. Despite the intense heat of California's central valley and Sierra foothills, and absence of precipitation during dry summer months, blue oaks are winter deciduous, and rely on a suite of drought adaptation measures for highly-efficient water use. To date, much more is known about aboveground dynamics in semi-arid oak savanna ecosystems than belowground. Yet, the root system is instrumental in ensuring oak survival and in determining the magnitude and timing of land-atmospheric fluxes via its control of water and nutrient supply to aboveground processes and soil moisture content. Tree root distribution is notoriously heterogeneous. Therefore a comprehensive sampling effort is needed in order to optimally represent it. To further understand the patterns of water use in oak savanna ecosystems in the Sierra foothills of California, we have sought to characterize the root system by depth. To accomplish this goal, we have sampled the root system using conventional sampling methods (i.e. pit and core sampling), in conjunction with ground penetrating radar (GPR). Using both methods together made it possible to compensate for the limitations of each: Fine roots can only be detected by conventional sampling, and involve time intensive work in the lab, limiting sample size. GPR, on the other hand, allows for much greater spatial coverage and therefore more comprehensive characterization of the coarse root component. An extensive field campaign was executed during May 2011. 7 tree areas where chosen, representing the range of tree sizes and composition at the research site: 2 small trees, 2 large trees and 2 tree clusters. One additional very large tree that has undergone extensive additional physiological measurements was also chosen in order to posit and test hypotheses about linkages among root, soil

  13. Physics-Based Spectra of Accretion Disks around Black Holes

    2005-01-01

    The purpose of this grant was to begin the process of deriving the light output of accretion disks around black holes directly from the actual processes that inject heat into the accreting matter, rather than from guessed dependences of heating rate on physical parameters. At JHU, the effort has focussed so far on models of accretion onto "intermediate mass black holes", a possible class of black holes, examples of which may have recently been discovered in nearby galaxies. There, Krolik and his student (Yawei Hui) have computed stellar atmospheres for uniformly-heated disks around this class of black holes. Their models serve two purposes: they are the very first serious attempts to compute the spectrum from accreting black holes in this mass range; and a library of such models can be used later in this program as contrasts for those computed on the basis of real disk dynamics. The output from these local disk calculations has also been successfully coupled to a program that applies the appropriate relativistic transformations and computes photon trajectories in order to predict the spectrum received by observers located at different polar angles. The principal new result of these calculations is the discovery of potentially observable ionization edges of H-like C and O at frequencies near the peak in flux from these objects. Most of the grant money at UCSB was spent on supporting graduate student Shane Davis. In addition. some money was spent on supporting two other students: Ari Socrates (now a Hubble Fellow at Princeton), and Laura Melling. Davis spent the year constructing stellar atmosphere models of accretion disks appropriate for the high/soft (thermal) state of black hole X-ray binaries. As with AGN models published previously by our collaboration with NASA support. our models include a complete general relativistic treatment of both the disk structure and the propagation of photons from the disk to a distant observer. They also include all important

    This paper investigates the shock-layer radiative heating uncertainty for hyperbolic Earth entry, with the main focus being a Mars return. In Part I of this work, a baseline simulation approach involving the LAURA Navier-Stokes code with coupled ablation and radiation is presented, with the HARA radiation code being used for the radiation predictions. Flight cases representative of peak-heating Mars or asteroid return are de ned and the strong influence of coupled ablation and radiation on their aerothermodynamic environments are shown. Structural uncertainties inherent in the baseline simulations are identified, with turbulence modeling, precursor absorption, grid convergence, and radiation transport uncertainties combining for a +34% and ..24% structural uncertainty on the radiative heating. A parametric uncertainty analysis, which assumes interval uncertainties, is presented. This analysis accounts for uncertainties in the radiation models as well as heat of formation uncertainties in the flow field model. Discussions and references are provided to support the uncertainty range chosen for each parameter. A parametric uncertainty of +47.3% and -28.3% is computed for the stagnation-point radiative heating for the 15 km/s Mars-return case. A breakdown of the largest individual uncertainty contributors is presented, which includes C3 Swings cross-section, photoionization edge shift, and Opacity Project atomic lines. Combining the structural and parametric uncertainty components results in a total uncertainty of +81.3% and ..52.3% for the Mars-return case. In Part II, the computational technique and uncertainty analysis presented in Part I are applied to 1960s era shock-tube and constricted-arc experimental cases. It is shown that experiments contain shock layer temperatures and radiative ux values relevant to the Mars-return cases of present interest. Comparisons between the predictions and measurements, accounting for the uncertainty in both, are made for a range

    chert deposition, as well as the onset of the oceanic anoxic event itself, is related to eccentricity maxima. The stable 405-kyr periodicity of eccentricity is readily discernible in the data records and can be used for tuning to the astronomical solution (Laskar et al. 2011). A total of five and a half 405-kyr cycles can be identified below the Bonarelli level, which itself comprises a 405-kyr cycle. This cyclostratigraphy can potentially be anchored to the absolute time scale by using the newly determined Cenomanian-Turonian boundary age of 93.9 ± 0.15 Ma, which is based on intercalibration of astrochronological and radioisotopic data for the Cenomanian-Turonian boundary interval near the GSSP in Colorado, USA (Meyers et al., 2012). Correlation to the orbitally tuned Turonian interval of the nearby Gubbio and Contessa sections in Italy (De Vleeschouwer et al., this session) allows the construction of an anchored astronomical time scale for the Cenomanian-Turonian interval of > 5 Ma.

    2016-01-01

    For Earth re-entry at velocities between 8 and 11.5 km/s, the accuracy of NASA's computational uid dynamic and radiative simulations of non-equilibrium shock layer radiation is assessed through comparisons with measurements. These measurements were obtained in the NASA Ames Research Center's Electric Arc Shock Tube (EAST) facility. The experiments were aimed at measuring the spatially and spectrally resolved radiance at relevant entry conditions for both an approximate Earth atmosphere (79% N2 : 21% O2 by mole) as well as a more accurate composition featuring the trace species Ar and CO2 (78.08% N2 : 20.95% O2 : 0.04% CO2 : 0.93% Ar by mole). The experiments were configured to target a wide range of conditions, of which shots from 8 to 11.5 km/s at 0.2 Torr (26.7 Pa) are examined in this paper. The non-equilibrium component was chosen to be the focus of this study as it can account for a significant percentage of the emitted radiation for Earth re-entry, and more importantly, non-equilibrium has traditionally been assigned a large uncertainty for vehicle design. The main goals of this study are to present the shock tube data in the form of a non-equilibrium metric, evaluate the level of agreement between the experiment and simulations, identify key discrepancies and to examine critical aspects of modeling non-equilibrium radiating flows. Radiance pro les integrated over discreet wavelength regions, ranging from the Vacuum Ultra Violet (VUV) through to the Near Infra-Red (NIR), were compared in order to maximize both the spectral coverage and the number of experiments that could be used in the analysis. A previously defined non-equilibrium metric has been used to allow comparisons with several shots and reveal trends in the data. Overall, LAURA/HARA is shown to under-predict EAST by as much as 40% and over-predict by as much as 12% depending on the shock speed. DPLR/NEQAIR is shown to under-predict EAST by as much as 50% and over-predict by as much as 20% depending

  20. Supernova Explosions Stay In Shape

    At a very early age, children learn how to classify objects according to their shape. Now, new research suggests studying the shape of the aftermath of supernovas may allow astronomers to do the same. A new study of images from NASA's Chandra X-ray Observatory on supernova remnants - the debris from exploded stars - shows that the symmetry of the remnants, or lack thereof, reveals how the star exploded. This is an important discovery because it shows that the remnants retain information about how the star exploded even though hundreds or thousands of years have passed. "It's almost like the supernova remnants have a 'memory' of the original explosion," said Laura Lopez of the University of California at Santa Cruz, who led the study. "This is the first time anyone has systematically compared the shape of these remnants in X-rays in this way." Astronomers sort supernovas into several categories, or "types", based on properties observed days after the explosion and which reflect very different physical mechanisms that cause stars to explode. But, since observed remnants of supernovas are leftover from explosions that occurred long ago, other methods are needed to accurately classify the original supernovas. Lopez and colleagues focused on the relatively young supernova remnants that exhibited strong X-ray emission from silicon ejected by the explosion so as to rule out the effects of interstellar matter surrounding the explosion. Their analysis showed that the X-ray images of the ejecta can be used to identify the way the star exploded. The team studied 17 supernova remnants both in the Milky Way galaxy and a neighboring galaxy, the Large Magellanic Cloud. For each of these remnants there is independent information about the type of supernova involved, based not on the shape of the remnant but, for example, on the elements observed in it. The researchers found that one type of supernova explosion - the so-called Type Ia - left behind relatively symmetric, circular

  2. PUBLISHER'S ANNOUNCEMENT: Refereeing standards

    NASA Astrophysics Data System (ADS)

    Bender, C.; Scriven, N.

    2004-08-01

    On 1 January 2004 I will be assuming the position of Editor-in-Chief of Journal of Physics A: Mathematical and General (J. Phys. A). I am flattered at the confidence expressed in my ability to carry out this challenging job and I will try hard to justify this confidence. The previous Editor-in-Chief, Ed Corrigan, has worked tirelessly for the last five years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements. Before accepting the position of Editor-in-Chief, I visited the office of J. Phys. A to examine the organization and to assess its strengths and weaknesses. This office is located at the Institute of Physics Publishing (IOPP) headquarters in Bristol. J. Phys. A has been expanding rapidly and now publishes at the rate of nearly 1000 articles (or about 14,000 pages) per year. The entire operation of the journal is conducted in a very small space---about 15 square metres! Working in this space are six highly intelligent, talented, hard working, and dedicated people: Neil Scriven, Publisher; Mike Williams, Publishing Editor; Rose Gray and Sarah Nadin, Publishing Administrators; Laura Smith and Steve Richards, Production Editors. In this small space every day about eight submitted manuscripts are downloaded from the computer or received in the post. These papers are then processed and catalogued, referees are selected, and the papers are sent out for evaluation. In this small space the referees' reports are received, publication decisions are made, and accepted articles are then published quickly by IOPP. The whole operation is amazingly efficient. Indeed, one of the great strengths of J. Phys. A is the speed at which papers are processed. The average time between the receipt of a manuscript and an editorial decision is under sixty days. (Many distinguished journals take three to five times this amount of time.) This speed of publication is an extremely strong enticement for

  4. Novel Quantum Monte Carlo Approaches for Quantum Liquids

    Rubenstein, Brenda M.

    the eventual hope is to apply this algorithm to the exploration of yet unidentified high-pressure, low-temperature phases of hydrogen, I employ this algorithm to determine whether or not quantum hard spheres can form a low-temperature bcc solid if exchange is not taken into account. In the final chapter of this thesis, I use Path Integral Monte Carlo once again to explore whether glassy para-hydrogen exhibits superfluidity. Physicists have long searched for ways to coax hydrogen into becoming a superfluid. I present evidence that, while glassy hydrogen does not crystallize at the temperatures at which hydrogen might become a superfluid, it nevertheless does not exhibit superfluidity. This is because the average binding energy per p-H2 molecule poses a severe barrier to exchange regardless of whether the system is crystalline. All in all, this work extends the reach of Quantum Monte Carlo methods to new systems and brings the power of existing methods to bear on new problems. Portions of this work have been published in Rubenstein, PRE (2010) and Rubenstein, PRA (2012) [167;169].

    shoot out from the black hole at close to the speed of light and then release their energy as radiation as far out as they are seen, the particles have to be accelerated locally, where they produce their emission. Both teams also used data from the third of NASA's Great Observatories, the Hubble Space Telescope, and the radio telescopes of the Very Large Array (VLA). The three space telescopes and the VLA "see" emission of different wavelengths from celestial objects, and the combined data was essential to reveal the new comprehensive perspective on the jets. "The new observations show that the flow structure of this jet is more complicated than had been assumed previously," Jester explains. "That the present evidence favors the synchrotron model deepens the mystery of how jets produce the ultra-energetic particles that radiate at X-ray wavelengths." "Our results call for a radical rethink of the physics of relativistic jets that black holes drive," said Uchiyama. "But, we now have a crucial new clue to solving one of the major mysteries in high-energy astrophysics." Other authors on the papers include Jeffrey Van Duyne and Paolo Coppi at Yale; C.C. Cheung at Stanford University; Rita Sambruna at NASA/GSFC, Greenbelt, MD; Tadayuki Takahashi at ISAS/JAXA, Japan; Laura Maraschi and Fabrizio Tavecchio at the Osservatorio Astronomico di Brera, Milan; Dan Harris from the SAO; Herman Marshall at MIT; and Klaus Meisenheimer at Max Planck Institute for Astronomy in Heidelberg.

  6. Jets Spout Far Closer to Black Hole Than Thought, Scientists Say

    NASA Astrophysics Data System (ADS)

    2004-01-01

    Scientists at the Massachusetts Institute of Technology, taking advantage of multiple unique views of black hole particle jets over the course of a year with NASA's Chandra X-ray Observatory, have assembled a "picture" of the region that has revealed several key discoveries. They have found that the jets may be originating five times closer to the black hole than previously thought; they see in better detail how these jets change with time and distance from the black hole; and they could use this information as a new technique to measure black hole mass. Presented today in a press conference at the meeting of the American Astronomical Society in Atlanta, the observation will ultimately help solve the mystery of the great cosmic contradiction, in which black holes, notorious for pulling matter in, somehow manage to also shoot matter away in particle jets moving close to the speed of light. The observation is of a familiar source named SS 433 -- a binary star system within our Galaxy in the constellation Aquila, the Eagle, about 16,000 light years away. The black hole and its companion are about two-thirds closer to each other than the planet Mercury is to the Sun. The jets shoot off at 175 million miles per hour, 26 percent of light speed. "The high-speed jets in nearby SS 433 may be caused by the same mechanisms as the powerful outflows in the most distant and much more massive black holes, such as quasars," said Laura Lopez, an undergraduate student at MIT and lead author on a paper about the result. "SS 433 provides a nice local laboratory to study the formation of and conditions in relativistic jets." Dr. Herman Marshall, Ms. Lopez's research supervisor, led the investigation. Matter from the companion star pours into the black hole via a swirling accretion disk, much like water down a drain. Black hole particles jets are thought to be produced as some of the matter encounters strong magnetic fields close to the black hole. SS 433 is angled in such a way that

Without their generous help and great effort, it would have been impossible for me to organize, reach all the goals and finally, successfully realize the workshop. We are also grateful for the financial support of CLAF (Centro Latino American de Fisica), Fonacit (Fondo Nacional de Ciencia Investigacion y Tecnología), IVIC (Instituto Venezolano de Investigaciones Cientificos), Fundacion Banco Mercantil, whose sponsorship and finnacial support were vital to the realization of the event. We would like to thank La Universidad del Zulia, Universidad Central de Venezuela, Instituto Universitario de Tecnología, IDEA (Instituto de Estudios Avanzados), and Asociación de Amigos de la Universidad Simón Bolivar for their help and support in different ways for the good results we achieved in most of the meetings and the participation of their students who attend the Workshops. Finally we appreciate very much the Ministry for Science and Technology (Ministerio del Poder Popular para la Ciencia y la Tecnología) for their contribution to the workshops and to the publication process. We are under the impression that our meeting was successful, as we expected, and we are thankful for the collaboration of our Institution, and the close relation we had with all the physics researchers of Latin America and abroad (Europe, USA, Australia and Russia). Lastly, many thanks to the invited speakers for their lectures presented which have given a whole overview of the state of the art in different areas of the Physics of Plasma.

They also thank Richard Binzel, the General Editor of the Space Science Series, for his strong support and advice during this process, as well as the staff at the University of Arizona Press. Finally, editor Patrick Michel would like to thank his wife Delphine, who married him on June 14, 2013, almost at the birth of the book process. He is grateful that she was willing to put up with him as he spent many of his nights and weekends working on the book. Thanks to her support, their trajectories are as bounded as a perfectly stable asteroid binary system, and this was probably the best way to experience from the start what her life would be like with a researcher! Co-editor Bottke would also like to thank his wife Veronica and his children Kristina-Marie, Laura, and Julie, who make up his own favorite asteroid family. Since Asteroids III, the size distribution of the family members has been steadily changing, and who knows how many tiny new members it will contain by Asteroids V! Co-editor DeMeo would like to thank her husband Alfredo for his support and encouragement throughout the process of creating this book. They met at the beginning of her career in research, becoming an asteroid pair and now continuing on the same orbit in life.

    Seaquist, E. R.

    2007-12-01

    With the passing of Donald Alexander MacRae on 6 December 2006 at age 90, the astronomy community lost a visionary scientist and a great educator in the field. Don MacRae was born in Halifax, Nova Scotia, on 19 February 1916, to Donald Alexander and Laura Geddes (Barnstead) MacRae. His father was originally a classics scholar and preceptor of Greek and Latin at Princeton, but at the time of Don's birth in 1916 he was Dean of the Dalhousie Law School in Halifax. The family moved to Toronto, Ontario, in 1924 when his father joined the faculty of Osgoode Hall Law School in Toronto as a Professor of Law. After the family moved to Toronto, where he received most of his early education, he obtained his undergraduate degree in Mathematics and Physics in 1937 from the University of Toronto (U of T). He obtained the degree of A.M. in 1940 and of Ph.D. in 1943 from Harvard University under the mentorship of Bart Bok in the field of galactic structure. During his early career he worked briefly at the University of Pennsylvania, Cornell University, and Carbide and Chemical Corporation at Oak Ridge, Tennessee. For Don the latter work was a brief and somewhat uneasy association with the Manhattan Project. In 1946, he obtained a position at Case Institute of Technology (now Case Western Reserve University), where he worked until 1953. In 1953, he accepted a position at the U of T, replacing Ralph Williamson, who had earlier introduced Don to the emerging field of radio astronomy while they both were at Cornell. Don's primary research field was stellar spectroscopy, but his interests were much broader than this, and he possessed an abiding ability to interest students and faculty in new and emerging ideas. In the early 1960s he developed a strong interest in the nature and origin of the lunar surface, and discussed these extensively with colleagues. Many of his ideas on this subject were later confirmed by the lunar exploration program. Don's continuing interest in radio astronomy

    and November 2009, and will cover 5000 kilometres. The voyage will largely take place across the Altiplano, or high plateau, shared by Peru, Bolivia and Chile, which is among the poorest regions in these countries. South America and the Andes Mountains were particularly chosen for the GalileoMobile Project for several reasons. IYA2009 already has a strong presence in the region through national contacts, including three Cornerstone IYA2009 projects: Developing Astronomy Globally, Universe Awareness and the Galileo Teacher Training Programme, which are all official partners of the project. Most people in Peru, Bolivia and Chile speak the same language, Spanish [1], and have a rich astronomical heritage dating back to the pre-Columbian Inca and Tiwanaku civilisations that lived on the Altiplano. The region's high elevation and the quality of its skies for astronomical observations also made it an attractive candidate for the maiden voyage of the GalileoMobile. The journey starts today 5 October 2009 in Antofagasta, Chile, with a free, public inauguration event at 19:00 in the Berta González Square at the Universidad Católica del Norte. The event, which will include observations of the night sky, is organised by ESO in collaboration with Explora II Region and the Astronomy Institute of the University. From Antofagasta the GalileoMobile heads north through La Paz in Bolivia and on into Peru. The return trip to Antofagasta goes via the Panamericana coastal road, and passes near the home of ESO's world-class observatory, the Very Large Telescope at Cerro Paranal. ESO Education and Outreach coordinator in Chile, Laura Ventura, will assist the GalileoMobile team as they greet communities throughout Chile's northern deserts. "The GalileoMobile is a wonderful initiative, and a unique opportunity to reinforce educational activities in the north of Chile and the neighbouring countries. It will promote greater awareness of astronomy and science", says Ventura. "We are looking

    .4 meter mirror, which caused the Hubble's initial focusing problems, while being photographed in real time by all the press cameras. A straight forward fix was devised for the WFPCII camera to bring the images into sharp focus. Once the repaired camera and the Hubble Space Telescope were safely in orbit, Westphal and his collaborators began receiving data on a regular basis. One of the early images of distant galaxies provided especially compelling evidence for the phenomenon known as gravitational lensing. "When this picture came in," Westphal said in a 1995 interview for Caltech's Engineering and Science magazine, "I put it under [Caltech physicist] Kip Thorne's door with a note saying, if you ever have any doubt about gravitational lenses, here's your proof." He was a member of the American Astronomical Society and served as the chairman of the Division for Planetary Sciences in 1979-1980. In 1991 Westphal received a MacArthur Fellowship. Already a tenured faculty member and the author of scores of refereed journal articles, and the creator of 15 patented inventions, Westphal was named director of Palomar Observatory in 1995 and served for three years. This assignment included being Caltech's representative to the Cara Board (which managed the KECK telescope). After lowering one of his custom-designed instruments into Old Faithful at Yellowstone National Park to study the geyser's cycling mechanism, he published a paper with Caltech graduate, Sue Kieffer, in 1997. The work, which received a good deal of media attention, confirmed previous assumptions about the geyser and also uncovered new details about the eruption cycle. Westphal took Caltech emeritus status in 1998, but remained active in research endeavors until his bout with this illness.

    such women pursued higher education. The role of women as "chemical assistants" to leading chemists of the day is well illustrated in the lives of du Chatelet, Paulze-Lavoisier, Picardet, and Necker de Saussure. Sadly, all this ended with the French Revolution when the woman intellectual became unacceptable. Chapter 3 focuses on a few exceptional women of the 1800-1900s who succeeded independently in their scientific work in an era when, without access to universities and financial resources, it was almost impossible to function other than as a "chemical assistant". This chapter gives a fascinating account of the life and work of five women, including Elizabeth Fulhame, who is credited with the discovery of photoreduction and the concept of catalysis, and Agnes Pockels, who, without formal education or laboratory facilities, pioneered research in surface films. By the 1850s, access to advanced education for women began in earnest. Chapter 4 tells of this radical change and its ramifications. This most readable account of the cultural conflicts that existed in Europe and the United States over educating women, admitting them to professional societies, and gaining faculty appointments is exemplified in the biographies of four U.S. women (Ellen Swallow Richards, Rachel Lloyd, Laura Linton, Ida Freund) and two Russian women (Yulya Lermontova and Vera Bogdanovskaia). Much of the content of the book resides in the remaining chapters (5-10) and covers 20th century science through 1950. The titles, Women in: Crystallography (Chapter 5), Radioactivity (Chapter 6), Biochemistry (Chapter 7), Industrial Chemistry (Chapter 8), Analytical, Education and History (Chapter 9), suggest that women favored some areas of chemistry over others. Why did they tend to congregate in certain fields? The authors give cogent reasons why this was so. They observe that, in developing fields, there was initially a collegiality among colleagues and the support of senior mentors that established a

L'effet de discontinuité entre les individus et entre les groupes est la tendance des relations entre les groupes à être plus compétitives que les relations entre les individus. Cet effet fut fermement démontré dans des études menées aux États-Unis, une société caractérisée d' «individualiste». Dans la présente étude, nous avons exploré dans quelle mesure l'effet était applicable à une société «collectiviste» comme le Japon. À partir du point de vue traditionnel de la psychologie interculturelle, laquelle met l'emphase sur la nature collectiviste des peuples de l'Asie de l'Est, il était attendu que l'effet de discontinuité allait être plus grand au Japon qu'aux États-Unis. D'un autre côté, se basant sur les données empiriques récentes qui suggèrent que les Nord-américains ne sont pas moins orientés vers le groupe que les Asiatiques de l'Est, il était attendu que l'effet de discontinuité ne serait pas plus important au Japon qu'aux États-Unis.

    million light-years (1 Mpc) from the radio galaxy, and probably in the surrounding cluster. The team has pinpointed a total of 26 objects in the surrounding field that may be companion galaxies with fainter hydrogen emission. The detection by the VLT of the huge gas halo and of the companion galaxies is further evidence that 1138-262 is a massive galaxy, forming in a group or cluster of galaxies. The next step The next step in the project will be to confirm the distances of the candidate companion galaxies and establish that they are indeed members of a cluster of galaxies surrounding 1138-262 . This can be done using one of the spectrographs on the VLT. Note [1] The project on 1138-262 is being carried out by a large international consortium of scientists led by astronomers from the Leiden Observatory. Besides George Miley and Huub Rottgering , the team includes Jaron Kurk , Laura Pentericci , and Bram Venemans (Leiden), Alan Moorwood (ESO), Chris Carilli (US National Radio Astronomy Observatory - NRAO), Wil van Breugel (University of California, USA) Holland Ford and Tim Heckman (Johns Hopkins University, Baltimore, USA) and Pat McCarthy (Carnegie Institute, Pasadena, USA). Technical information about the VLT images of 1138-262 Narrow and broad-band imaging was carried out on April 12 and 13, 1999, with the ESO VLT ANTU (UT1), using the FORS1 multi-mode instrument in imaging mode. A narrow-band filter was used which has a central wavelength of 381.4 nm and a bandpass of 6.5 nm. For 1138-262 (redshift z = 2.2), the emission of Lyman-alpha at 121.6 nm is redshifted to 383.8 nm, which falls in this narrow band. The broad-band filter was a Bessel-B with central wavelength of 429.0 nm. The detector was a Tektronix CCD with 2048 x 2046 pixels and an image scale of 0.20 arcsec/pixel. Eight separate 30-min exposures were taken in the narrow band and six 5-min in the broad band, shifted by about 20 arcsec with respect to each other to minimize problems due to flat-fielding and

    Fred Whipple, one of the founding fathers of planetary science, died on August 30, 2004 just two months shy of his 98th birthday. The breadth of Fred's published research from 1927 through 2000 is quite extraordinary. Although his collected works were published in two massive volumes in 1972, shortly before his retirement, Fred's research contributions continued for another three decades - and another volume is planned. Fred Lawrence Whipple was born on November 5, 1906 on a farm in Red Oak Iowa. His parents were Harry Lawrence and Celestia (MacFarl) Whipple. At the age of fifteen, the Whipple family moved to California where Fred studied mathematics at Occidental College and the University of California at Los Angeles. As a graduate student at the University of California at Berkeley in 1930, he was one of the first to compute an orbit for the newly discovered planet Pluto. Upon receiving his PhD in 1931, he joined the staff of the Harvard College Observatory. He was Chairman of the Harvard Department of Astronomy (1949 - 1956), Director or the Smithsonian Astrophysical Observatory (1955 - 1973), Phillips Professor of Astronomy (1968 - 1977) and Emeritus Phillips Professor of astronomy (1977 - 2004). In 1928 he married Dorothy Woods and their son, Earle Raymond, survives him. The marriage ended in divorce in 1935. Eleven years later, he married Babette F. Samelson and she too survives him, as do their two daughters Laura and (Dorothy) Sandra. Shortly after arriving at Harvard in the early 1930's, Fred developed a photographic tracking network to determine meteor trajectories from simultaneous observations from two or more stations. The photographic trails, chopped by a rotating shutter, allowed their orbits in space to be determined accurately. With the strong involvement of Richard McCrosky and others, he concluded in the early 1960's that most of these meteors were on comet-like orbits and less than 1% of the naked eye, sporadic meteors could be traced to an

    living in Santa Cruz; two daughters, Laura of Seattle, Washington, and Carol of Santa Cruz; and three grandchildren. Don did a theoretical Ph.D. thesis with Chandrasekhar calculating the effects of gravitational interactions between interstellar clouds and stars, but arguably his best known graduate work was observational in nature, helping Morgan map the nearest spiral arms of our Galaxy. Morgan put Don's name on the landmark 1952 paper (Morgan, Sharpless, & Osterbrock, AJ, 57, p. 3, 1952), even though, according to Don's own account in his 2000 autobiography A Fortunate Life in Astronomy, the work was mostly Morgan's. This generous gesture by Morgan likely fashioned what was to become Don's own trademark generosity towards his Ph.D. students and colleagues for years to come. After obtaining his Ph.D. degree, Don spent a single but very productive year as a postdoctoral fellow at Princeton University, becoming interested in the stellar structures of red dwarfs. Using numerical integration methods generously provided by Martin Schwarzschild, Don produced the first models of red dwarfs that took into account their outer convective layers (Osterbrock, ApJ, 118, pp. 529-546, 1953). These calculations also inspired Fred Hoyle and Schwarzschild to successfully model red giant stars with similar convective envelopes. In 1953, Osterbrock accepted an instructorship at Caltech, joining a young astronomy department led by Jesse Greenstein. Direct access to Caltech's outstanding astronomical facilities on Mounts Wilson and Palomar marked a turning point in Don's career, since it allowed him to pursue his observational interests in gaseous nebulae. Drawing on his expertise in atomic physics, and a very productive collaboration via air mail with young atomic theorist Michael Seaton, he pioneered the use of spectroscopic methods for the study of gaseous nebulae. In a daring move in 1958, Don left Caltech for the University of Wisconsin, to appease his wife's and his own homesickness

Other members are Jaron Kurk and Huub Röttgering (also Leiden University), Laura Pentericci (MPIA, Heidelberg, Germany), Wil van Breugel (Lawrence Livermore National Laboratory, USA), Chris Carilli (US National Radio Astronomy Observatory, Charlottesville, USA), Carlos De Breuck (Institut d'Astrophysique, Paris, France) Holland Ford and Tim Heckman (Johns Hopkins University, Baltimore, USA) and Pat McCarthy (Carnegie Institute, Pasadena, USA). [2]: The measured redshift of TN J1338-1942 is z = 4.1. In astronomy, the redshift denotes the fraction by which the lines in the spectrum of an object are shifted towards longer wavelengths. The observed redshift of a remote galaxy provides an estimate of its distance. The distances indicated in the present text are based on an age of the Universe of 15 billion years. At the indicated redshift, the Lyman-alpha line of atomic hydrogen (rest wavelength 121.6 nm) is observed at 620 nm, i.e. in the red spectral region.

    are described, but in the end it is appears that only infrared astrometry and astrometry would allow to detect the presence of the planets around this star. Denmark: Mr. Joern C. Olsen, Mr. Henrik Struckmann, Mr. Uffe A. Hansen, Mr. Mogens Winther (Teacher) (Soenderborg Amtsgymnasium) This team performed extensive CCD-observations with the school telescope of three stellar clusters. The goal was to determine their HR-diagrammes (colour-magnitude) and other characteristics. Among others, the team succeeded to measure quite accurate B (blue) and V (green-yellow) colours of 40, 12-16-magnitude stars in the open stellar cluster NGC 6939. This allowed a determination of the distance (2500 parsec) to this cluster and its age (1800 million years), quite similar to the `professionally' determined values. As a side-result, and illustrating the faintness of starlight, a calculation showed that it would take no less than 437,236 years for the brightest star in the sky, Sirius, to heat a cup of coffee to the boiling point ! Finland: Mr. Reima EresmA, Ms. Laura Elina Nykyri, Ms. Reetamaija Janhonen (Cygnaeues-Lukeo, Jyvaeskylae and Jyvaeskylae Lyseon Lukeo) This group used a 50-cm amateur telescope in their home town to observe the spectra of galaxies. A CCD spectrograph recorded the data which were then image-processed in the computer. For this programme, five galaxy pairs were selected and their velocities were measured. This allowed to calculate the distance to the galaxies by means of Hubble's law and also to determine the velocity difference between the two galaxies in a binary system. This in turn makes it possible to estimate the galaxies' total mass. When comparing these numbers with the mass of the visible objects, the group finally determined that the visible mass is only about 8 percent of the total mass, i.e. there must be much `dark matter' in these galaxies.
