The Walters Art Museum  

NSDL National Science Digital Library

Bequeathed to the city of Baltimore in 1931 by Henry Walters, the Walters Art Museum now contains 28,000 works of art spanning 55 centuries. Henry's father, William, started the collection, and first brought his art to the public in the spring of 1874 by opening his home every Wednesday for two months, charging the public 50 cents for admission, and giving the proceeds to charity. The Works of Art tab near the top of the homepage provides multiple ways of viewing the thousands of works of art from the museum that are available online. Many of the pieces are accompanied by detailed descriptions. The Artwork of the Day allows visitors to read about the details of a highlighted piece simply by clicking on its image. Visitors may also view past artworks of the day by clicking on the back arrow above the image. Another way for visitors to see the collection, through the eyes of public curators, is by checking out the Community Collections feature, which shows the collections that people have created themselves from the works of art online. Diamonds, babies, and pointing fingers are some of the themes.

Walter C. Williams  

NASA Technical Reports Server (NTRS)

Walter C. Williams arrived from the National Advisory Committee for Aeronautics, Langley Memorial Aeronautical Laboratory, Hampton, Virginia, on September 30, 1946, at the Muroc Army Air Field. He had been named the engineer-in-charge of the small group of five that came with him to the Rogers Dry Lakebed to take part in research flights of a joint NACA-Army Air Forces program involving the rocket-powered Bell XS-1. This established the first permanent National Advisory Committee for Aeronautics presence at the Mojave Desert site in California. This small group grew in numbers to 27 and received permanent status as the NACA Muroc Flight Test Unit from Hugh L. Dryden, NACA's Director of Research, on September 27, 1947. Walt was named Head of the Unit. On November 14, 1949, the Unit along with the 100 employees became the NACA High-Speed Flight Research Station with Walt Williams as Chief. Next came the move from the South Base site to the new headquarters, Bldg. 4800 on the north-west shore of the Rogers Dry lakebed on the Edwards Air Force Base complex. July 1, 1954 saw another name change to the NACA High-Speed Flight Station with Walt remaining the Chief to a complement of about 225 employees. Williams had received a Bachelor of Science Degree in aeronautical engineering from Louisiana State University, Baton Rouge, Louisiana, in 1939. After graduation, he was employed by the Glenn L. Martin Company of Baltimore, Maryland, and later that same year joined the staff of the NACA Langley Memorial Aeronautical Laboratory, where he worked as an engineer in the Flight Division. During the period from September 1946 to July 1954 Williams supervised the activities of several research projects. These included the first successful rocket-powered flight of the XS-1 made by Bell pilot Chalmers Goodlin on December 9, 1946; the record breaking flight of A.F. Captain Chuck Yeager on October 14, 1947, that exceeded the speed of sound; and the first flight of the jet-powered Douglas D-558-1 Skystreak by NACA pilot Howard C. Lilly on November 25, 1947. On March 10, 1948, Herbert Hoover was the first NACA pilot and the first civilian to fly supersonically (in the XS-1). Then came the testing of the tailless Northrop X-4 aircraft; the first flight of the variably swept wing Bell X-5 made by NACA pilot Joseph A. Walker; the first NACA flight of the Convair XF-92A, a delta wing configuration, on April 9, 1953; followed by the first Mach 2 flight on November 20, 1953, flown by NACA pilot Scott Crossfield in the rocket-powered Douglas D-558-2 Skyrocket. Walt continued to be in charge during the many name changes for the NACA-NASA organization, ending his stay as Chief of the National Aeronautics and Space Administration's Flight Research Center (todays NASA's Dryden Flight Research Center) in September 1959. See DIRECTORS, E-1364 for further information on Walter C. Williams.

Walter Gordon Collection of Photographs  

NSDL National Science Digital Library

In the first half of the 20th century, the well-known African American attorney Walter L. Gordon had his office next to the African American newspaper, the California Eagle. The photographers for the paper often shot pictures of Black social life in Los Angeles, and once printed these photos were often discarded. Gordon saved many of these photos and began collecting the images, which often depicted leading members of the Black community in Los Angeles. His collection made its way to UCLA, and their digital collections group digitized over 800 of his photographs. Here visitors will find images of black resorts such as Val Verde, local political figures, and a range of jazz legends, such as Count Basie and Billie Holliday. Currently, visitors can view almost 300 of these items, and they can browse the photos by language, name, subject, or type. There are some real gems in here, including a great photo of Lionel Hampton on the stage and a cast photo of the members of "Carmen Jones" at an informal gathering. The image viewer here is quite impressive, as visitors can add a grid of select photos for comparative viewing and also manipulate each image as they see fit.

NASA Astrophysics Data System (ADS)

On March 19, 1996, the scientific community lost one of its greatest champions and chroniclers, Walter S. Sullivan. He died in his home in Riverside, Conn.Sullivan was the first recipient of the American Geophysical Union's Award for Excellence in Science Journalism, which appropriately bears his name. Born on January 18, 1918, he joined The New York Times as a copy boy in 1940. After serving in the Navy during World War II, he became a foreign correspondent for the Times in 1946, only making a definitive switch to science reporting 10 years later, immediately before the International Geophysical Year, whose story he eloquently detailed. He joined AGU in 1957 and remained a member until his death. In 1962, he became the science news editor of the Times and, from 1964 until his retirement in 1987, he was the overall science editor. He continued his science writing into retirement, coming into the office to write an occasional article until shortly before his death.

Obituary: Walter G. Egan, 1923-2003  

NASA Astrophysics Data System (ADS)

Walter G. Egan, a scientist and engineer with a professional life spanning well over half a century, died on 3 November 2003. Born to Caroline and George Egan on 12 October 1923 in New York City, Egan studied Electrical Engineering at the City College of New York from 1941 until 1943 when he was called to active duty in World War II, switching from enlisted reserve status. During the war, he served honorably in both the Signal Corps and the Medical Corps. Following his discharge in 1946, he resumed his college studies, obtaining a BEE in 1949 from City College of New York, an MA in Physics in 1951 from Columbia University, and a PhD in Solid State Physics in 1960 from the Polytechnic Institute of Brooklyn. Egan's PhD thesis was "Ferromagnetic Resonance in thin Nickel Films," performed under advisor H. Juretschke. Egan's professional career covered both industry and academia. In the summer of 1942, he worked for the Bruce Engineering Company. From 1957 to 1963, he worked for Ford Instrument Company, a Division of Sperry Rand Corporation, successively as an Engineering Project Supervisor, Assistant Director of Research, and Executive Assistant to the Director of Research. From 1964 to 1986 Egan worked as a Staff Scientist at the Grumman Corporation Corporate Research Center where his pioneering work consisted of research and development of remote sensing equipment and techniques for the remote sensing of terrestrial and space targets and backgrounds. I came to know and work with him during his tenure at the Grumman Corporation, where we co-authored many papers and a book. His insight into remote sensing engineering and research, shared willingly with younger colleagues, was a major stimulus to my future research in this field. Egan instilled a sense of discipline in publication, so our work could be shared with others in a timely way. This drive to share his knowledge with others also made him an excellent teacher. Subsequently, he held the position of Research Associate at the Mohonk Preserve, New Paltz, New York; Professor of Physics at York College, City University of New York; Research Professor of Physics at Polytechnic University, Brooklyn New York; and Professor of Earth Sciences at Adelphi University, Garden City, New York. Research was the focus of his professional life. At various points in his career Egan was a member of Tau Beta Pi, Sigma Xi, Eta Kappa Nu, Sigma Pi Sigma, the American Radio Relay League, the Research Society of America, the American Physical Society, the American Astronomical Society, the Institute of Electrical and Electronic Engineers, the American Geophysical Union, the Optical Society of America, the American Meteorological Society, the Institute for Aerosol Research, and the Society of Photo-optical Instrumentation Engineers. A long and distinguished professional career was accompanied by more than two-hundred published works in the fields of Planetary Astronomy, Geophysics, Atmospheric Physics, Soils Physics, Materials Properties, Photometry, Polarization, Remote Sensing, Aerosols, Oceanography, and Optics. We co-wrote the book Optical Properties of Inhomogeneous Materials (Academic Press) in 1979. This was followed by Egan's two books on remote sensing: Photometry and Polarization in Remote Sensing (Elsevier) in 1985 and Optical Remote Sensing, Science and Technology (Marcel Dekker) in 2004. These books have become classical references in today's remote sensing courses. He brought clarity to this burgeoning field of research at a time when it was just developing. Egan is survived by his wife, Joan K. Egan. He also leaves behind many younger colleagues, myself included, who considered him both a mentor and a friend.

Walter's two-layer hypothesis revisited: back to the roots!  

PubMed

Walter (Jahrb Wiss Bot 87:750-860, 1939) proposed a two-layer hypothesis, an equilibrium explanation for coexistence of savanna trees and grasses. This hypothesis relies on vertical niche partitioning and assumed that grasses are more water-use efficient than trees and use subsurface water while trees also have access to deeper water sources. Thus, in open savannas, grasses were predicted to predominate because of their water use efficiency and access to subsurface water. This hypothesis has been a prominent part of the savanna literature since first proposed. We review the literature on Walter's hypothesis and reconsider his original intentions. Walter intended this hypothesis to be restricted to dry savannas. In his opinion, mesic and humid savannas were controlled by biotic factors and disturbances. We surveyed the global savanna literature for records of vertical niche partitioning by grasses and trees. We find that, within the scope of Walter's original intentions, this hypothesis works remarkably well, and in some cases is appropriate for deserts as well as for dry temperate systems and even some mesic savannas.

Walter Langbein and the emergence of scientific hydrology  

NASA Astrophysics Data System (ADS)

Walter Langbein (1907-1982) contributed to the growth of scientific hydrology in a number of ways. His research publications introduced original concepts of both theoretical interest and practical importance. He served on a number of committees of the American Geophysical Union and played a key role in promoting new approaches in hydrological thinking. He played a major role in the launching of the International Hydrological Decade of 1965-1974 and in the establishment of the International Association of Hydrological Sciences Committee on Mathematical Models in Hydrology in 1967. He was a source of inspiration to many young hydrologists who have since made their own important individual contributions to that discipline. It is timely and useful to look back at his personal contribution to hydrology and to draw lessons on it for our future work.

Walter C. Williams with Brig. General Albert Boyd  

NASA Technical Reports Server (NTRS)

Walter C. Williams, (behind airplane model) Head of the National Advisory Committee for Aeronautics High-Speed Flight Research Station at Edwards Air Force Base in California is examining a Northrop X-4 research airplane with Brig. Gen. Albert Boyd, Commander of Edwards Air Force Base. At Edwards, the Air Force Air Material Command ran a brief program on the X-4 during the summer of 1950 before delivering it to the NACA. Data was collected on these 14 flights, so they were logged as NACA test flights. General Boyd made flight number 13. Air Force and NACA pilots completed a total of 82 flights on X-4 #2 (46-677) between August 1950 and September 1953. There are three things that made the Mojave Desert, where Edwards Air Force Base is located, so well suited for flight research. The first was the area's flying conditions--clear skies with great visibility almost every day of the year. The second was the 44-square-mile Rogers Dry Lake, a natural landing site that General Boyd referred to as 'God's gift to the Air Force.' The third was the unpopulated area surrounding the lakebed, which led to fewer complaints about aircraft noise (including sonic booms) than would have occurred in more populated areas. There was also less chance of injury to the surrounding population in the event of an aircraft accident.

New functions and applications of walter, the sweating fabric manikin.  

PubMed

In this paper, latest developments on Walter, a sweating fabric manikin, are reported. These include the improved simulation of "walking motion", the design and construction of an automated water supply, and real-time measurement of evaporative water loss and regulation of "skin" temperature through the regulation of the pumps inside the manikin body. Testing of commercial garment ensembles showed that the measurement of thermal insulation and moisture-vapour resistance of clothing is very reproducible with the coefficient of variation being generally less than 5%. It was also shown that, in addition to the thermal insulation and moisture-vapour resistance, the percentage of moisture accumulation within clothing is a very useful parameter of clothing comfort. The improved manikin has been used to investigate the effects of walking motion on thermal insulation and evaporative resistance of clothing. The trend of the effects of walking speed up to 1.13 m s(-1) for the nude manikin and when it was wearing garments of different sizes are reported. PMID:15138829

Walter C. Williams Research Aircraft Integration Facility (RAIF)  

NASA Technical Reports Server (NTRS)

The NASA-Dryden Integrated Test Facility (ITF), also known as the Walter C. Williams Research Aircraft Integration Facility (RAIF), provides an environment for conducting efficient and thorough testing of advanced, highly integrated research aircraft. Flight test confidence is greatly enhanced by the ability to qualify interactive aircraft systems in a controlled environment. In the ITF, each element of a flight vehicle can be regulated and monitored in real time as it interacts with the rest of the aircraft systems. Testing in the ITF is accomplished through automated techniques in which the research aircraft is interfaced to a high-fidelity real-time simulation. Electric and hydraulic power are also supplied, allowing all systems except the engines to function as if in flight. The testing process is controlled by an engineering workstation that sets up initial conditions for a test, initiates the test run, monitors its progress, and archives the data generated. The workstation is also capable of analyzing results of individual tests, comparing results of multiple tests, and producing reports. The computers used in the automated aircraft testing process are also capable of operating in a stand-alone mode with a simulation cockpit, complete with its own instruments and controls. Control law development and modification, aerodynamic, propulsion, guidance model qualification, and flight planning -- functions traditionally associated with real-time simulation -- can all be performed in this manner. The Remotely Augmented Vehicles (RAV) function, now located in the ITF, is a mainstay in the research techniques employed at Dryden. This function is used for tests that are too dangerous for direct human involvement or for which computational capacity does not exist onboard a research aircraft. RAV provides the researcher with a ground-based computer that is radio linked to the test aircraft during actual flight. The Ground Vibration Testing (GVT) system, formerly housed in the Thermostructural Laboratory, now also resides in the ITF. In preparing a research aircraft for flight testing, it is vital to measure its structural frequencies and mode shapes and compare results to the models used in design analysis. The final function performed in the ITF is routine aircraft maintenance. This includes preflight and post-flight instrumentation checks and the servicing of hydraulics, avionics, and engines necessary on any research aircraft. Aircraft are not merely moved to the ITF for automated testing purposes but are housed there throughout their flight test programs.

Walter C. McCrone (1916-2002) was a special person. While books, journals and ledgers record over 400 of his technical contributions, his true legacy is his inspiration and leadership. In remembering "Doc" McCrone, we honor a man dedicated to people, to science and to education. His passion for microscopy was only exceeded by his love of science, people and teaching. While he ranked microscopy as the first step in every scientific investigation he made use of all technologies in formulating and testing hypotheses. Everyone who met Walter has a story to tell of this man's impact on his or her life; I will tell you mine. PMID:15027542

Geographic intersections of regional science: Reflections on Walter Isard's contributions to geography  

NASA Astrophysics Data System (ADS)

. In his writing, analyses, and commentaries, Walter Isard contributed significantly to economic geography, inspiring a generation of economic geographers with seminal texts on industrial location and spatial economics and methods of regional analysis - a line of argumentation that explicitly incorporated economic reasoning into an otherwise largely descriptive and inventory-based subdiscipline of geography. His circumscribed view of regional development and industrial location helped precipitate the emergence of the critical turn in economic geography in the late 1970s. He was the one early modern 20th century economics author to successfully wed economics and a certain perspective on space.

Labors of love: the transformation of care in the Non-Medical Attendant program at Walter Reed Army Medical Center.  

PubMed

In this paper, we explore the Non-Medical Attendant program at Walter Reed Army Medical Center in Washington, DC, which subsidizes the presence of war-injured soldiers' family members as they live for months or even years at Walter Reed during treatment and rehabilitation. We elaborate the ambiguities of the program and draw on ethnographic research to demonstrate how the program's vagaries combine with the context of an overburdened military medical system and the more familiar strains of family caregiving to place family members in a gray zone of care where the line between labors of love and institutionally compensated work is blurred.

Site remediation considerations and foundation excavation plan for the Walter Reed Army Institute of Research building, Forest Glen, Maryland  

SciTech Connect

The US Army Corps of Engineers North Atlantic Division, Baltimore District (CENAB), intends to design and construct a medical and dental research facility for the Walter Reed Army Institute of Research (WRAIR) at the Walter Reed Army Medical Center (WRAMC) at Forest Glen, Maryland. Because almost 100% of the proposed building site is located on an uncontrolled landfill that was thought to possibly contain medical, toxic, radioactive, or hazardous waste, it was assumed that remediation of the site might be necessary prior to or in conjunction with excavation. To assess (1) the need for remediation and (2) the potential hazards to construction workers and the general population, the Baltimore District contracted with Argonne National Laboratory to undertake a site characterization and risk assessment and to develop a foundation-excavation plan. The results of the site characterization and a qualitative risk assessment have been presented in a previous report. This report presents the foundation-excavation plan. 38 refs., 16 figs., 11 tabs.

Walter Reed Army Medical Center's mental health response to the Pentagon attack.  

PubMed

The September 11 terrorist attack on the Pentagon captured the attention and concern of America as well as the world. Given the extent of devastation, and the number of deaths at the Pentagon, it was believed that the uniformed mental health services would serve a pivotal role in the recovery and relief efforts. This article provides a synopsis of the complex and multidisciplinary mental health services provided by Walter Reed Army Medical Center in the wake of the September 11 attack on the Pentagon. This article offers an overview of the functions and roles of mental health team members, describes a constellation of services rendered, and describes how missions differed inside and outside of the Pentagon. Additionally, the authors provide the reader with how services were provided at the Family Assistance Center to family members of those killed during the attack. Liaison with civilian medical, mental health, and relief agencies and facilities will be discussed as well. The mental health response was an intensive and complicated experience and has yielded many lesson learned. To this end, the authors will provide the reader with an understanding of how the lessons learned during this mission may assist mental health commanders and leaders in planning and responding to similar deployments in the future.

Alfred Walter Campbell and the visual functions of the occipital cortex.  

PubMed

In his pioneering cytoarchitectonic studies of the human brain, Alfred Walter Campbell identified two structurally different areas in the occipital lobes and assigned two different kinds of visual functions to them. The first area, the visuosensory, was essentially on the mesial surface of the calcarine fissure. It was the terminus of nervous impulses generated in the retina and was where simple visual sensations arose. The second area, the visuopsychic, which surrounded or invested the first, was where sensations were interpreted and elaborated into visual perceptions. I argue that Campbell's distinction between the two areas was the starting point for the eventual differentiation of areas V1-V5. After a brief outline of Campbell's early life and education in Australia and of his Scottish medical education and early work as a pathologist at the Lancashire County Lunatic Asylum at Rainhill near Liverpool, I summarise his work on the human brain. In describing the structures he identified in the occipital lobes, I analyse the similarities and differences between them and the related structures identified by Joseph Shaw Bolton. I conclude by proposing some reasons for how that work came to be overshadowed by the later studies of Brodmann and for the more general lack of recognition given Campbell and his work. Those reasons include the effect of the controversies precipitated by Campbell's alliance with Charles Sherrington over the functions of the sensory and motor cortices. PMID:23218905

Walter Baade, Dynamical Astronomer at Goettingen, Hamburg, Mount Wilson, and Palomar Observatories  

NASA Astrophysics Data System (ADS)

Walter Baade, famous for his astrophysical discoveries, also made many contributions in dynamical astronomy. His thesis at Goettingen University on the spectroscopic orbit of ? Lyrae was based on spectrograms his teacher, Johannes Hartmann, had taken at Potsdam years earlier. Immediately on receiving his Ph.D. in 1919, Baade joined the Hamburg Bergedorf Observatory staff, and soon was the sole observer with its 1-m reflector, the largest telescope in Europe. Under its director, Richard Schorr, Baade's main job at first was to obtain direct plates of asteroids and comets for positional measurements. As an incidental part of this observing he discovered many asteroids, eight of which were eventually named, including 966 Muschi (his wife's nickname), 944 Hidalgo, with large orbital semi-major axis, eccentricity, and inclination, and 1036 Ganymed, whose orbit extends inside that of Mars. Baade also discovered a new comet, 1922 II. During the close approach of Eros in 1930 Baade measured its period of light variation, its color, and its mean magnitude. After Pluto was discovered in 1930 he measured its position assiduously, following it as far from opposition as he could. In 1931 Baade moved to Mount Wilson, where he concentrated almost entirely on globular-cluster, supernova, and galaxy research. He saw many asteroid trails on his long exposures but did not report them except for one, 7448 (still not named), which showed a very long trail on a 3-hr exposure of the Crab nebula. At Palomar, using the 48-in Schmidt soon after it went into operation, he dicovered and reported 1566 Icarus, with a very small perihelion distance, and later his second comet, 1955 VI.

Walter Baade, Fritz Zwicky, and Rudolph Minkowski's Early Supernova Research, 1927 - 1973  

NASA Astrophysics Data System (ADS)

Long before he ``discovered" the two stellar populations, Walter Baade was a pioneer in research on supernovae and their remnants. In 1927, while still in Germany, Baade emphasized what he called ``Hauptnovae" (chief novae) as highly luminous, potential distance indicators. He joined the Mount Wilson staff in 1931, bringing the ``secret" of the Schmidt camera with him, and encouraged Fritz Zwicky to carry out a supernova search with one at Palomar. Baade and Zwicky used the term ``supernova" in their 1933 joint paper. Zwicky began a systematic search in 1936, and Baade followed up with the 100-in reflector to derive light curves. He confirmed that Tycho's ``nova" of 1572 and the Crab nebula had been supernovae in our Galaxy. Baade advised N. U. Mayall, at Lick, on his spectroscopic study of the Crab nebula. In 1933, after Hitler came to power, Rudolph Minkowski had to leave Germany. Baade managed to get him a Mount Wilson staff position. Minkowski then did the spectroscopic observations of supernovae, beginning in 1937. Within a few years he and Baade were able to distinguish type I and II supernovae. Baade's further work on supernovae included historical research in Latin, Italian, and German, as well as filter photography. He searched hard for a remnant of SN 1885 in M 31, but never succeeded in finding it. After World War II the Crab nebula was found to be a strong radio source, and Baade and Minkowski used the 200-in to identify other supernova remnants, beginning with Cas A. Baade collaborated closely with Jan Oort and his student, Lo Woltjer, in their studies of the Crab nebula. After Baade retired in 1958, Minkowski continued supernova research for more than a decade; one of his favorite objects was the expanding Cygnus Loop.

The Walter Reed staging classification for HTLV-III/LAV infection.  

PubMed

Patients with acquired immunodeficiency syndrome (AIDS) represent a minority of those who have been infected with human T-lymphotropic virus type III (HTLV-III). The clinical presentation of patients with HTLV-III infections can range from asymptomatic through chronic generalized lymphadenopathy, to subclinical and clinical T-cell deficiency. The US Army has recently adopted a staging classification for HTLV-III infection. The purpose of the Walter Reed (WR) staging Classification is to provide uniformity for routine clinical evaluation of military personnel with HTLV-III infection, to facilitate understanding of the natural history of these infections, and to help evaluate the clinical response to antiviral treatment regimens. Stage WR0 designates high-risk contacts, while stages WR1-6 require documentation of HTLV-III infection. Stages WR1-6 show ascending degrees of disease, so that those classified in WR6 manifest antibodies to HTLV-III, chronic lymphadenopathy, T helper cell counts below the normal limit, delayed hypersensitivity, thrush, and opportunistic infection. HTLV-III infections with symptoms are designated by the addition of the letter B, while the occurrence of Kaposi's sarcoma is designated by adding the letter K. This classification scheme is based on the fact that the T helper cell is the principal target cell of HTLV-III and the clinical observation that the functional integrity of the T helper cell determines the clinical presentation. Preliminary studies in 39 sequential patients followed for over 18 months found that patients who entered in stages WR3-WR6 had a slow but progressive course to the next stage or death. Many questions about clinical progression remain, but it is hoped that this staging classification will facilitate their resolution. PMID:2934633

Further evaluation of the Walter Reed Visual Assessment Scale: correlation with curve pattern and radiological deformity  

PubMed Central

Background The Walter Reed Visual Assessment Scale (WRVAS) was designed to measure physical deformity as perceived by patients with idiopathic scoliosis. Previous studies have shown that the instrument has excellent internal consistency and a high correlation with the radiological magnitude of scoliotic curves. Nonetheless, it is not known whether the scale can discriminate between the various curve patterns of the deformity, or whether the deformities represented in the scale's drawings relate to the corresponding radiological deformities. Methods This study included 101 patients (86 women and 15 men; mean age 19.4 years) with idiopathic scoliosis. In a single visit, patients underwent standing PA radiography of the spine and completed the WRVAS. X-ray measurements included: 1) magnitude (Cobb angle) of the proximal thoracic curve (PT), main thoracic curve (MT), and thoracolumbar/lumbar curve (TL/L); 2) difference in shoulder level; 3) T1 offset from the central sacral line (T1-CSL); 4) apical vertebra (apV) rotation at the MT and TL/L curves and 5) apical vertebra offset of the MT and TL/L curves from the central sacral line. A variable designated Cobbmax was defined as the largest angle of the three curves (PT, MT or TL/L). Patients were grouped onto three patterns: Thoracic (TH Group)(n = 30, mean MT 42.1°, TL/L 20.9°); double major (DM Group) (n = 39, mean MT 38.6°, TL/L 34.4°) and thoracolumbar (TL Group)(n = 32, mean MT 14.3°, TL/L 25.5°). The magnitude of the curves in the TL Group was significantly smaller than in the other groups (P < 0.05). The Spearman partial correlation coefficient was determined between the score for each WRVAS question and the curve pattern, adjusting for the Cobbmax variable. The Spearman correlation coefficient was determined between the WRVAS items and shoulder imbalance, T1-CSL offset, MT Cobb angle, MT apV rotation, MT apV offset, PT Cobb, TL/L Cobb, TL/L apV rotation and TL/L apV offset. Results The median (interquartile range) of the total WRVAS score was 14 (IQR 6). No correlation was found between the curve pattern and the various scores on the scale (partial correlation coefficients ranged from -0.16 to 0.12). WRVAS drawings for items 1, 2, 4 and 7 correlated satisfactorily with the corresponding radiological measurements (correlation coefficients, 0.62, 0.3, 0.48 and 0.53, respectively). Items 3, 5 and 6 did not correlate with the radiological measurements (correlation coefficients -0.06, -0.07 and 0.05, respectively). Conclusion The profile of the individual WRVAS scores does not differentiate among specific curve patterns (thoracic, double major and thoracolumbar/lumbar). Moreover, some of the drawings (items 3, 5 and 6) do not correlate with the radiological deformity they were designed to measure.

8-Aminoquinolines from Walter Reed Army Institute for Research for treatment and prophylaxis of Pneumocystis pneumonia in rat models.  

PubMed Central

Three 8-aminoquinolines from the Walter Reed Army Institute for Research (WRAIR), WR6026, WR238605, and WR242511, strongly inhibited Pneumocystis carinii growth in vitro at 1 microgram/ml. This activity was similar to that of primaquine. In rat therapy models, the WRAIR compounds affected Pneumocystis pneumonia at doses as low as 0.25 mg/kg (WR242511) or 0.5 mg/kg (WR6026 and WR238605). At these doses, primaquine alone was ineffective as therapy. In a rat prophylaxis model, all three WRAIR 8-aminoquinolines were extremely effective at daily doses of 0.57 mg/kg, showing activity greater than that of primaquine at this dosage and comparable to that of trimethoprim-sulfamethoxazole at 50/250 mg/kg.

The proposed eight-acre building site for the Walter Reed Army Institute of Research (WRAIR) facility is a former uncontrolled landfill. As a prerequisite to foundation design and to formulation of an excavation plan, it was necessary to characterize the landfill materials and to conduct a qualitative human risk assessment. Chemical analysis of surface-water, groundwater, and landfill soils followed the analytical protocol promulgated under the US Environmental Protection Agency's (EPA's) Contract Laboratory Program for its Target Compound List of contaminants. This protocol was used to determine concentrations of volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs) polychlorinated biphenyls (PCBs)/pesticides, inorganic compounds, radioactive materials, asbestos, and many of the metals analyzed. 49 refs., 19 figs., 24 tabs.

"THE CASUAL CRUELTY OF OUR PREJUDICES": ON WALTER LIPPMANN'S THEORY OF STEREOTYPE AND ITS "OBLITERATION" IN PSYCHOLOGY AND SOCIAL SCIENCE.  

PubMed

Reflecting on his wartime government service, Walter Lippmann (1922) developed a theory of policy formulation and error. Introducing the constructs of stereotype, mental model, blind spots, and the process of manufacturing consent, his theory prescribed interdisciplinary social science as a tool for enhancing policy making in business and government. Lippmann used his influence with the Rockefeller foundations, business leaders, Harvard and the University of Chicago to gain support for this program. Citation analysis of references to "stereotype" and Lippmann reveals the rapid spread of the concept across the social sciences and in public discourse paralleled by obliteration by incorporation of the wider theory in behavioral science. "Stereotype" is increasingly invoked in anthropology, economics, and sociology though Lippmann and his wider theory ceased being cited decades ago. In psychology, citations are increasing but content analysis revealed blind spots and misconceptions about the theory and prescription. Studies of heuristics, biases, and organizational decision substantiate Lippmann's theory of judgment and choice. But his model for social science failed to consider the bounded rationality and blind spots of its practitioners. Policy formulation today is supported by research from narrow disciplinary silos not interdisciplinary science that reflects an awareness of history. PMID:22936385

Physiological and biochemical mechanisms of allelopathy mediated by the allelochemical extracts of Phytolacca latbenia (Moq.) H. Walter.  

PubMed

In allelopathy, one plant suppresses the growth and development of other plant/plants by negatively affecting a variety of physiological and biochemical reactions. We checked the effects of methanolic extracts (allelochemical extracts) of Phytolacca latbenia (Moq.) H. Walter on antioxidant enzyme activities such as peroxidases (PODs), super oxide dismutases (SODs) and catalase (CAT) and on total protein contents (TPC), cellular injury (CI), and malondialdehyde (MDA) in the germinating seeds of Brassica napus L. (dicot) and Triticum aestivum L. (monocot). Both the crude methanolic extract root (CMER) and crude methanolic extract aerial (CMEA) of P. latbenia at 10000 ppm significantly reduced the POD activity in both the test seeds. The activity of SODs was significantly decreased by both CMER and CMEA in B. napus germinating seeds. A linear increase in the activity of CAT, CI, and MDA contents was found in both the test seeds with the increasing concentrations of CMEA and CMER, while TPC of the germinating seeds was found decreased. It is inferred that both the CMEA and CMER inhibited/delayed the seed germination, reduced the seedling growth by affecting a variety of biochemical and physiological attributes, and also caused cellular membrane injury in the germinating seeds of both the monocot and dicot seeds.

Dewatering of the Clayton Formation during construction of the Walter F George Lock and Dam, Fort Gaines, Clay County, Georgia  

USGS Publications Warehouse

Walter F. George Lock and Dam, the largest manmade structure in the South, extends over 2llz miles across the flood plain of the Chattahoochee River at Fort Gaines, Clay County, in southwest Georgia and in Henry County, in southeast Alabama. The multipurpose dam consists of two rolled-filled earth dikes, a concrete spillway, a single-stage lock with an 88-foot lift, and a 130,000 kilowatt capacity powerhouse. The foundation of the dam at the river is constructed in the Clayton Formation, and the earth dikes are constructed on river terraces at about 150 feet above msl (mean sea level). At the damsite, the top of the Clayton Formation consists of an "earthy" limestone, which is about 35 feet thick except in the river channel, where it is 12 to 15 feet thick; a "shell" limestone, which averages about 40 feet thick; and a basal "sandy" limestone, which averages about 35 feet thick. The Providence Sand underlies the "sandy" limestone and its thickness is about 175 feet at the damsite. These formations contain water under artesian conditions. The "shell" unit of the Clayton was the principal water-bearing formation pumped during construction of the lock and dam. The large yields of the wells from concentrated areas over extended periods of time indicate that in the vicinity of the Chattahoochee River, the Clayton Formation is a productive aquifer with transmissivity ranging from 48,000 to 77,000 gpd per ft. (gallons per day per foot) and storage coefficient ranging from 2.5 x 10?3 to 2.8 x 10?5. At the spillway site, pumpage ranged from an average of 1,700 to 8,400 gpm (gallons per minute) during the period April 1957 to July 1959; at the powerhouse site, pumpage ranged from 1,600 to 5,000 gpm during the period October 1957 to September 1961; and at the lock site, pumpage ranged from 4,000 to 5,000 gpm during the period July 1960 through December 1961. The large yields represent a source of large quantities of ground water available for industrial and other uses in an area readily accessihle by barge from the Gulf of Mexico to Columbus, Ga. During dewatering, the potentiometric surface was lowered from a pre-pumping altitude of about 115 to 120 feet above msl to a minimum altitude of about 40 feet above msl, or near the bottom of the "shell" limestone. The stage of the Chattahoochee River ranged from about 20 to 60 feet above the potentiometric surface at the dewatering sites. The Chattahoochee River seemingly is recharging the Clayton Formation near the damsite, possibly through large solution cavities such as were observed during construction of the spillway site at the river. Furthermore, a "honeycombed" network of large solution holes caused the collapse of a section of "earthy" limestone near the powerhouse site. Some underground leakage is expected to occur at the damsite because of the cavernous condition of the limestone, particularly on the Alabama side of the river.

Complement levels and circulating immune complexes in a controlled, longitudinal, multicentre study on effects of intravenous immunoglobulin in adults with AIDS-related complex/Walter-Reed 5. The ARC-IVIG Study Group.  

PubMed

The complement system, as the effector mechanism of the antigen-antibody reaction, and the levels of circulating immune complexes in a 1-year, double-blind, randomized, placebo-controlled study served as laboratory parameters to assess the effect of long-term high-dose intravenous immunoglobulin (IVIG) therapy in 30 adult patients (2 x 15) with AIDS-related complex/Walter-Reed 5 (ARC/WR5). We obtained no evidence of an adverse effect in such patients of high-dose IVIG administered over a 6-month period: none of the parameters studied showed a significant difference between the two groups of patients. In both groups, using data before the first infusion or using data of the whole study, a correlation between circulating immune complexes and classical complement pathway activation was found. The most striking increase was seen in the two groups of patients for functional serum factor D. The accumulation of serum factor D was not paralleled by an increase in serum creatinine. In patients with disease progressing from ARC to AIDS within the study period, an accumulation of serum factor D was not more or less pronounced than in those who remained in the ARC stage. Accumulation of factor D was not related to the clinical score as assessed in this study. PMID:2238575

Evaluation of genetic variability in micropropagated propagules of ornamental pineapple [Ananas comosus var. bracteatus (Lindley) Coppens and Leal] using RAPD markers.  

PubMed

The objective of the present study was to evaluate the genetic variability in micropropagated plantlets of ornamental pineapple, after the fourth period of subculture. The basal culture medium consisted of MS salts, vitamins, 3% sucrose, liquid formulation, supplemented with 6-benzylaminopurine (BAP) at concentrations of 0.125, 0.25, 0.5, 1.0, and 2.0 mg/L. The addition of BAP influenced the occurrence of genetic variation revealed using random amplified polymorphic DNA (RAPD) markers. Of a total of 520 primers tested, 44 were selected and amplified; 402 monomorphic bands (97.2%) and 18 polymorphic bands (2.8%) resulted among regenerated plantlets. The polymorphic fragments were produced by 12 primers (OPA-01, OPA-20, OPB-01, OPB-19, OPC-19, OPF-13, OPL-17, OPM-13, OPP-16, OPT-07, OPV-19, and OPX-03). Among the primers that identified polymorphism, OPA-01, OPA-20, OPB-19, OPC-19, OPL-17, OPP-16, and OPX-3 each showed, one polymorphic band and OPF-13 amplified a maximum of three bands. In this study, the RAPD technique was effective in showing the occurrence of somaclonal variations that occur during the micropropagation process of ornamental pineapple cultivation in BAP-supplemented medium, and it is possible to detect the presence of genetic variation in early stages of plant development.

The human dengue challenge experience at the walter reed army institute of research.  

PubMed

Recent discordance between measured levels of serotypes of dengue virus neutralizing antibody and clinical outcomes suggests a need to reevaluate the process of prescreening dengue vaccine candidates to better predict their clinical benefit before initiation of large-scale human vaccine trials. In the absence of a reliable animal model for dengue, a human dengue virus challenge model (ie, a controlled live dengue virus infectious challenge study) may prove useful and timely to elucidate mechanisms that underlie protection (as well as virulence), thus facilitating down-selection of vaccine candidates before beginning advanced field trials. Dengue challenge studies were safely used in prior decades to study the vector biology, clinical spectrum of illness, and reactogenicity of candidate live dengue virus vaccines of uncertain attenuation. Redeveloping the human dengue challenge model following current regulatory guidance, good manufacturing practice, and good clinical practice could streamline and accelerate vaccine development by offering a time- and resource-efficient method to evaluate the safety and potential efficacy of dengue vaccine and therapeutic candidates. In this article, the development of such a challenge model and its subsequent application is summarized from 2 recent reports. PMID:24872396

The 1986 Walter Hubert lecture. Recent studies on a vaccine to prevent EB virus-associated cancers.  

PubMed Central

Epstein-Barr (EB) virus was discovered in 1964 (Epstein et al., 1964). In the decades since then an immense body of information has been accumulated on the virus and a great deal is now known about its general biological behaviour, its epidemiology, its molecular biology, the humoral and cellular immunological responses which it evokes, and about its relationship to human cancers. The fact that EB virus was thought from the outset to be a human tumour virus was no doubt responsible for the large number of laboratories in which it has been studied. Viruses causing tumours in animals have been known since early in the present century and affect frogs, fowl, rodents, rabbits, cats, cattle, monkeys and even fish (Klein, 1980). It was obvious that man could not be different in this respect and the finding of EB virus therefore promised to bring human tumours into line with those of other species.

CO2 Flux from a Subtropical Mangrove Ecosystem in Magdalena Bay BCS, Mexico Josediego Uribe, Walter C. Oechel  

NASA Astrophysics Data System (ADS)

Mangrove forests are among the most productive ecosystems within the tropical and subtropical coastlines of the world. There is currently limited research on mangrove carbon sequestration potentials but with ongoing climate change and rising atmospheric carbon dioxide (CO2) levels, an understanding of carbon exchange in mangroves forests and the environmental controls influencing fluxes is extremely important for understanding their role in the global carbon cycle and their potential as stores of CO2. In this study, CO2 flux was evaluated for a subtropical mangrove ecosystem in the arid region of Magdalena Bay BCS, Mexico. Measurements were taken using an eddy covariance system above the canopy during January 8 to the 30, and currently from June 21 to August 28, in 2012. The mangrove forest is located (N25° 15'75", W112° 04'79") near the town of Puerto Lopez Mateos, Mexico. During this time period environmental variables such as Net Radiation, photosynthetically active radiation (PAR), air temperature, humidity, ground heat flux, soil temperature and tidal height were measured together with the CO2 flux in order to determine the environmental influence on the fluxes. Preliminary results showed a clear diurnal pattern in CO2 flux that showed high sinks when light availability was high. During January, the winter dry season environmental conditions remained relatively cool with an average air temperature of 17 oC and consistently cloudless days. During this period CO2 flux was -1.3 ?mol C m-2s-1, which means that for the month of January, there was a net uptake of carbon by the mangrove ecosystem. For the summer period the development of the data collection for a longer term as well as further correlation analysis with environmental data is currently underway, however expectations are that seasonal variations of CO2 flux can be seen due to longer and more intense periods of solar irradiance as well as the effect of high temperature (+30° C) days. Indirect effects from seasonal trends in tidal height, and precipitation would also influence the strength of the mangrove uptake of carbon.

Libertarians favor a free market for intrinsic reasons: it embodies liberty, accountability, consent, cooperation, and other virtues. Additionally, if property rights against trespasses such as pollution are enforced and if public lands are transferred as private property to environmental groups, a free market may also protect the environment.

Low Energy Accelerator Laboratory Technical Area 53, Los Alamos National Laboratory. Environmental assessment  

SciTech Connect

This Environmental Assessment (EA) analyzes the potential environmental impacts that would be expected to occur if the Department of Energy (DOE) were to construct and operate a small research and development laboratory building at Technical Area (TA) 53 at the Los Alamos National Laboratory (LANL), Los Alamos, New Mexico. DOE proposes to construct a small building to be called the Low Energy Accelerator Laboratory (LEAL), at a previously cleared, bladed, and leveled quarter-acre site next to other facilities housing linear accelerator research activities at TA-53. Operations proposed for LEAL would consist of bench-scale research, development, and testing of the initial section of linear particle accelerators. This initial section consists of various components that are collectively called an injector system. The anticipated life span of the proposed development program would be about 15 years.

Evapotranspiration and Dual Crop Coefficients Sonisa Sharma1, Ayse Irmak12, Anne Parkhurst3, Elizabeth walter-Shea1 and Kenneth G. Hubbard1 1School of Natural Resources, 2Civil Engineering, 3Departments of Statistics, University of Nebraska-Lincoln  

NASA Astrophysics Data System (ADS)

Accurate estimation of water content in the crop root zone is most important for water conservation and management practices like irrigation. The objective of this study is to use the FA0-56 dual crop cefficients: basal crop coefficient Kcb and the soil evaporation coefficient Ke for a large corn/soybean field in the year 2005 at the Mead Turf Farm in the state of Nebraska, USA..Dual crop coefficients can be used to estimate both transpiration from crops and evaporation from soil. The Kcb has a low value of 0.15(K cb, in) during the initial period, increases rapidly to a maximum of 1.14 (K cb, mid) for the entire midseason and decreases rapidly to 0.5 at the end of the corn growing season (K cb,end). When examined together with precipitation, the dual crop coefficient was higher following rainfall or irrigation, as expected. The data suggests that the dual crop coefficient approach is a good estimation of water loss from well-watered crops. Irrigation can be scheduled to replace the loss of water from the crop/soil system. Similarly, when we compared the measured daily ET and the ET calculated from dual crop coefficients, it gives 98 % R2.; Comparision of calculated ET from dual crop coefficient appraoch with Weather Station ET

Restricted role for methionine synthase reductase defined by subcellular localization.  

PubMed

Methionine synthase reductase (MSR; gene name MTRR) is responsible for the reductive activation of methionine synthase. Cloning of the MTRR gene had revealed two major transcription start sites which, by alternative splicing, allows for two potential translation products of 698 and 725 amino acids. While the shorter protein was expected to target the cytosol where methionine synthase is located, the additional sequence in the longer protein was consistent with a role as a mitochondrial leader sequence. The possibility that MSR might target mitochondria was also suggested by the work of Leal et al. [N.A. Leal, H. Olteanu, R. Banerjee, T.A. Bobik, Human ATP:Cob(I)alamin adenosyltransferase and its interaction with methionine synthase reductase, J. Biol. Chem. 279 (2004) 47536-47542.] who showed that it can act as the reducing enzyme in combination with MMAB (ATP:Cob(I)alamin adenosyltransferase) to generate adenosylcobalamin from cob(II)alamin in vitro. Here we examined directly whether MSR protein is found in mitochondria. We show that, while two transcripts are produced by alternative splicing, the N-terminal segment of the putative mitochondrial form of MSR fused to GFP does not contain a sufficiently strong mitochondrial leader sequence to direct the fusion protein to the mitochondria of human fibroblasts. Further, antibodies to MSR protein localized MSR to the cytosol, but not to the mitochondria of human fibroblasts or the human hepatoma line Huh-1, as determined by Western blot analysis and immunofluorescence of cells in situ. These data confirm that MSR protein is restricted to the cytosol but, based on the Leal study, suggest that a similar protein may interact with MMAB to reduce the mitochondrial cobalamin substrate in the generation of adenosylcobalamin.

Free market environmentalism  

SciTech Connect

Free Market Environmentalism by Terry L. Anderson and Donald R. Leal is a call to action rather than an empirical study. These authors argue that the environment and the market are inextricably connected in a positive rather than negative way. In their view, individual property owners, who are in a position and have an incentive to obtain time- and place-specific information about their resource endowments, are better suited than centralized bureaucracies to manage resources. Government should strive as much as possible to encourage and facilitate the working of the market through the enforcement of property rights, including clearly specified titles, strict liability rules and adjudication of disputed property rights in court. Markets could then be created in a variety of environmental policy domains. For example, Yellowstone National park currently has a problem with migrating bison who wander off the park premises and infect the cattle of adjoining ranches with deadly viruses. To Anderson and Leal, this problem could be solved if park officials owned the bison and could be sued for damages. Overfishing could be solved through the allocation of property rights to specific people who would be allowed to trade their rights. This property rights model is applied to a wide variety of environmental circumstances and problems including land policy, outdoor recreation, energy development, groundwater pollution, garbage disposal, and global warming.

A least squares closure approximation for liquid crystalline polymers  

NASA Astrophysics Data System (ADS)

An introduction to existing closure schemes for the Doi-Hess kinetic theory of liquid crystalline polymers is provided. A new closure scheme is devised based on a least squares fit of a linear combination of the Doi, Tsuji-Rey, Hinch-Leal I, and Hinch-Leal II closure schemes. The orientation tensor and rate-of-strain tensor are fit separately using data generated from the kinetic solution of the Smoluchowski equation. The known behavior of the kinetic solution and existing closure schemes at equilibrium is compared with that of the new closure scheme. The performance of the proposed closure scheme in simple shear flow for a variety of shear rates and nematic polymer concentrations is examined, along with that of the four selected existing closure schemes. The flow phase diagram for the proposed closure scheme under the conditions of shear flow is constructed and compared with that of the kinetic solution. The study of the closure scheme is extended to the simulation of nematic polymers in plane Couette cells. The results are compared with existing kinetic simulations for a Landau-deGennes mesoscopic model with the application of a parameterized closure approximation. The proposed closure scheme is shown to produce a reasonable approximation to the kinetic results in the case of simple shear flow and plane Couette flow.

Interactions Forces and the Flow-Induced Coalescence of Drops and Bubbles  

NASA Technical Reports Server (NTRS)

In order to accomplish the proposed macroscale experimental goals, we designed and built a pair of miniaturized computer-controlled four-roll mills, similar but much smaller than the 4-roll mill that had been develop earlier in Prof. Leal's group for studies of drop deformation and breakup. This unique experimental facility allows for controlled experiments on the breakup and coalescence of very small drops in the size range of 20-200 micrometers in diameter for a wide variety of flows and under a wide range of flow conditions including time-dependent flows, etc. The small size of this device is necessary for coalescence studies, since coalescence occurs in viscous fluids at capillary numbers that are large enough to be experimentally accessible only for drops that are smaller than approximately 100_m in diameter. Using these miniaturized 4-roll mills, we have obtained the first quantitative data (so far as we are aware) on the flow-induced coalescence process.

Detection and separation of overlapping cells based on contour concavity for Leishmania images.  

PubMed

Life scientists often must count cells in microscopy images, which is a tedious and time-consuming task. Automatic approaches present a solution to this problem. Several procedures have been devised for this task, but the majority suffer from performance degradation in the case of cell overlap. In this article, we propose a method to determine the positions of macrophages and parasites in fluorescence images of Leishmania-infected macrophages. The proposed strategy is primarily based on blob detection, clustering, and separation using concave regions of the cells' contours. In comparison with the approaches of Nogueira (Master's thesis, Department of University of Porto Computer Science, 2011) and Leal et al. (Proceedings of the 9th international conference on Image Analysis and Recognition, Vol. II, ICIAR'12. Berlin, Heidelberg: Springer-Verlag; 2012. pp. 432-439), which also addressed this type of image, we conclude that the proposed methodology achieves better performance in the automatic annotation of Leishmania infections.

NASA Technical Reports Server (NTRS)

The Bubble and Drop Nonlinear Dynamics (BDND) experiment was designed to improve understanding of how the shape and behavior of bubbles respond to ultrasound pressure. By understanding this behavior, it may be possible to counteract complications bubbles cause during materials processing on the ground. This 12-second sequence came from video downlinked from STS-94, July 5 1997, MET:3/19:15 (approximate). The BDND guest investigator was Gary Leal of the University of California, Santa Barbara. The experiment was part of the space research investigations conducted during the Microgravity Science Laboratory-1R mission (STS-94, July 1-17 1997). Advanced fluid dynamics experiments will be a part of investigations plarned for the International Space Station.

Current Status of a Model System: The Gene Gp-9 and Its Association with Social Organization in Fire Ants  

PubMed Central

The Gp-9 gene in fire ants represents an important model system for studying the evolution of social organization in insects as well as a rich source of information relevant to other major evolutionary topics. An important feature of this system is that polymorphism in social organization is completely associated with allelic variation at Gp-9, such that single-queen colonies (monogyne form) include only inhabitants bearing B-like alleles while multiple-queen colonies (polygyne form) additionally include inhabitants bearing b-like alleles. A recent study of this system by Leal and Ishida (2008) made two major claims, the validity and significance of which we examine here. After reviewing existing literature, analyzing the methods and results of Leal and Ishida (2008), and generating new data from one of their study sites, we conclude that their claim that polygyny can occur in Solenopsis invicta in the U.S.A. in the absence of expression of the b-like allele Gp-9b is unfounded. Moreover, we argue that available information on insect OBPs (the family of proteins to which GP-9 belongs), on the evolutionary/population genetics of Gp-9, and on pheromonal/behavioral control of fire ant colony queen number fails to support their view that GP-9 plays no role in the chemosensory-mediated communication that underpins regulation of social organization. Our analyses lead us to conclude that there are no new reasons to question the existing consensus view of the Gp-9 system outlined in Gotzek and Ross (2007).

Induced flow in coalescence phenomena of droplets confined in a channel  

NASA Astrophysics Data System (ADS)

The authors focus on coalescence phenomena of liquid droplets in a circular tube. Especially, induced flow is investigated using fine particles when two liquid droplets coalesces. The particles are suspended in each or both droplets of O(mm) in diameter. Creeping motion of liquid droplets through a capillary tube is generally employed as a fundamental problem. As example applications, there are fluid handling technique, controlling chemical reaction and so on. The problem is also underlying basis on analyzing the flow of multiphase fluids through porous media[1]. Such phenomena can be seen, for instance, in enhanced oil recovery, breaking of emulsions in porous coalescers and so on[2]. Examples of studies of coalescence phenomena of droplets are flow-induced coalescence of viscous drops in a viscous fluid by Leal, et al.[3] and the interaction and coalescence of liquid droplets in flow through a capillary tube by Olbricht, et al.[2]. However, as far as the authors know, there have been no previous cases in which the induced flow is investigated when droplets coalesces. In this experiment, a vertical glass tube of 3.5 mm in inner diameter, 8 mm in outer diameter, and 1500 mm in length is used as a test tube. The test tube is filled with a quiescent fluid which is a mixture fluid of glycerol and pure water. Silicone oil droplets with suspended particles are successively injected into the test tube using micro-syringes. Behaviors of droplets and suspended particles are simultaneously monitored by a digital video camera, CCD cameras and high speed cameras placed on a sliding stage. The motion of the stage is electrically controlled to follow the travelling droplets in the tube. Coalescence time is measured. The coalescence time indicates a period between instances when the relative velocity of two droplets becomes zero after their apparent contact and when the coalescence takes place. The spatio-temporal behavior of the particles before/after the coalescence of the droplets takes place is reconstructed. Induced flow is investigated from the spatio-temporal images. Effect of suspended particles on the droplet coalescence is also discussed. [1]Olbricht, W. L., Ann. Rev. Fluid Mech., 28, pp.187-213,1996. [2]e.g.,Olbricht, W. L. and Kung, D. M., J.

A holistic strategy for adaptive land management  

USGS Publications Warehouse

Adaptive management is widely applied to natural resources management (Holling 1973; Walters and Holling 1990). Adaptive management can be generally defined as an iterative decision-making process that incorporates formulation of management objectives, actions designed to address these objectives, monitoring of results, and repeated adaptation of management until desired results are achieved (Brown and MacLeod 1996; Savory and Butterfield 1999). However, adaptive management is often criticized because very few projects ever complete more than one cycle, resulting in little adaptation and little knowledge gain (Lee 1999; Walters 2007). One significant criticism is that adaptive management is often used as a justification for undertaking actions with uncertain outcomes or as a surrogate for the development of specific, measurable indicators and monitoring programs (Lee 1999; Ruhl 2007).

The award was established in 1989 in honor of its first recipient, Walter Sullivan, science writer of The New York Times. The “paradise” of the title is the Kerguelen Plateau in the southern Indian Ocean, which was dry land some 100 million years ago, but is now, except for a few small islands, completely submerged. The plateau was explored under the auspices of the Ocean Drilling Program, which formed the basis of Witze's story. It may be seen at http://dallasnews.com/science/70455_witzestory.html.

Voyages and Travels: Ancient and Modern  

NSDL National Science Digital Library

Sir Walter Raleigh was a man who liked to travel the globe. He was in good company, as persons stretching all the way back to Herodotus (and before) had a certain wanderlust that could only be quenched by seeking out new lands and experiences. Some of their musings on the places they explored can be found within the electronic pages of the volume presented here by Bartleby.com. The Voyages and Travels work was originally part of the Harvard Classics series, and it contains seven accounts of travel and exploration. These accounts include "An Account of Egypt" by Herodotus, Sir Walter Raleigh's "The Discovery of Guiana", and a narrative of Sir Humphrey Gilbert's trip to Newfoundland in the 16th century.

In search of autonomic balance: the good, the bad, and the ugly  

PubMed Central

Walter B. Cannon's research on the sympathetic nervous system and neurochemical transmission was pioneering. Wisdom has endowed our body with a powerful autonomic neural regulation of the circulation that provides optimal perfusion of every organ in accordance to its metabolic needs. Exquisite sensors tuned to an optimal internal environment trigger central and peripheral sympathetic and parasympathetic motor neurons and allow desirable and beneficial adjustments to physiologic needs as well as to acute cardiovascular stresses. This short review, presented as The Walter B. Cannon Memorial Award Lecture for 2009, addresses the mechanisms that disrupt sensory signaling and result in a chronic maladjustment of the autonomic neural output that in many cardiovascular diseases results in excessive increases in the risks of dying. The hopes for any reduction of those risks resides in an understanding of the molecular determinants of neuronal signaling.

Metal/Silicate Partitioning of P, Ga, and W at High Pressures and Temperatures: Dependence on Silicate Melt Composition  

NASA Technical Reports Server (NTRS)

The distinctive pattern of element concentrations in the upper mantle provides essential evidence in our attempts to understand the accretion and differentiation of the Earth (e.g., Drake and Righter, 2002; Jones and Drake, 1986; Righter et al., 1997; Wanke 1981). Core formation is best investigated through use of metal/silicate partition coefficients for siderophile elements. The variables influencing partition coefficients are temperature, pressure, the major element compositions of the silicate and metal phases, and oxygen fugacity. Examples of studies investigating the effects of these variables on partitioning behavior are: composition of the metal phase by Capobianco et al. (1999) and Righter et al. (1997); silicate melt composition by Watson (1976), Walter and Thibault (1995), Hillgren et al. (1996), Jana and Walker (1997), and Jaeger and Drake (2000); and oxygen fugacity by Capobianco et al. (1999), and Walter and Thibault (1995). Here we address the relative influences of silicate melt composition, pressure and temperature.

Application of PIXE to the study of Renaissance style enamelled gold jewelry  

NASA Astrophysics Data System (ADS)

This study examines and compares three pieces of Renaissance style gold and enamelled jewelry owned by the Walters Art Gallery, Baltimore, MD, USA. These are a 16th century Hat Badge of Adam and Eve, a 19th century Fortitude Pendant and a Diana Pendant presumed to be of the 16th century (The Walters Art Gallery, Jewelry, Ancient to Modern (Viking, New York, 1979)), Ref. [1]. PIXE spectroscopy was applied to examine the elemental composition of the gold and of the enamels. Compositional differences, including the use of post-Renaissance colorants, were found between the enamels in separate regions of each of the three pieces. The modern colorant, chromium, was, in fact, found in all of the pieces and uranium was found in only the Diana Pendant. There are some differences in the gold purity of the three objects; there are significant differences in the solders used even within one object, the Fortitude Pendant.

MENA 1.1 - An Updated Geophysical Regionalization of the Middle East and North Africa  

SciTech Connect

This short report provides an update to the earlier LLNL paper entitled ''Preliminary Definition of Geophysical Regions for the Middle East and North Africa'' (Sweeney and Walter, 1998). This report is designed to be used in combination with that earlier paper. The reader is referred to Sweeney and Walter (1998) for all details, including definitions, references, uses, shortcomings, etc., of the regionalization process. In this report we will discuss only those regions in which we have changed the boundaries or velocity structure from that given by the original paper. The paper by Sweeney and Walter (1998) drew on a variety of sources to estimate a preliminary, first-order regionalization of the Middle East and North Africa (MENA), providing regional boundaries and velocity models within each region. The model attempts to properly account for major structural discontinuities and significant crustal thickness and velocity variations on a gross scale. The model can be used to extrapolate sparse calibration data within a distinct geophysical region. This model can also serve as a background model in the process of forming station calibration maps using intelligent interpolation techniques such as kriging, extending the calibration into aseismic areas. Such station maps can greatly improve the ability to locate and identify seismic events, which in turn improves the ability to seismically monitor for underground nuclear testing. The original model from Sweeney and Walter (1998) was digitized to a 1{sup o} resolution, for simplicity we will hereafter refer to this model as MENA 1.0. The new model described here has also been digitized to a 1{sup o} resolution and will be referred to as MENA1.1 throughout this report.

Microbial mats are stratified communities that develop within the environmental microgradients established at the interfaces of water and solid substrates (Cohen, 1989). Stromatolites, the lithified remains of layered accumulations of microbial mats, occur in rocks as old as 3.5 Ga (Lowe, 1980; Walter et al., 1980). These lithified microbial communities represent the most ancient, widespread ecosystems known, and it is useful to explore their role in the accumulation of free oxygen in the ancient atmosphere.

DEVELOPMENT OF A VALIDATED MODEL FOR USE IN MINIMIZING NOx EMISSIONS AND MAXIMIZING CARBON UTILIZATION WHEN CO-FIRING BIOMASS WITH COAL  

SciTech Connect

This is the eighth Quarterly Technical Report for DOE Cooperative Agreement No. DE-FC26-00NT40895. A statement of the project objectives is included in the Introduction of this report. The final biomass co-firing test burn was conducted during this quarter. In this test (Test 14), up to 20% by weight dry switchgrass was comilled with Jim Walters No.7 mine coal and injected through the single-register burner. Jim Walters No.7 coal is a low-volatility, low-sulfur ({approx}0.7% S) Eastern bituminous coal. The results of this test are presented in this quarterly report. Progress has continued to be made in implementing a modeling approach to combine reaction times and temperature distributions from computational fluid dynamic models of the pilot-scale combustion furnace with char burnout and chemical reaction kinetics to predict NO{sub x} emissions and unburned carbon levels in the furnace exhaust. The REI Configurable Fireside Simulator (CFS) is now in regular use. Presently, the CFS is being used to generate CFD calculations for completed tests with Powder River Basin coal and low-volatility (Jim Walters No.7 Mine) coal. Niksa Energy Associates will use the results of these CFD simulations to complete their validation of the NOx/LOI predictive model. Work has started on the project final report.

A Unified Mixed-Effects Model for Rare-Variant Association in Sequencing Studies  

PubMed Central

For rare-variant association analysis, due to extreme low frequencies of these variants, it is necessary to aggregate them by a prior set (e.g., genes and pathways) in order to achieve adequate power. In this paper, we consider hierarchical models to relate a set of rare variants to phenotype by modeling the effects of variants as a function of variant characteristics while allowing for variant-specific effect (heterogeneity). We derive a set of two score statistics, testing the group effect by variant characteristics and the heterogeneity effect. We make a novel modification to these score statistics so that they are independent under the null hypothesis and their asymptotic distributions can be derived. As a result, the computational burden is greatly reduced compared with permutation-based tests. Our approach provides a general testing framework for rare variants association, which includes many commonly used tests, such as the burden test [Li and Leal, 2008] and the sequence kernel association test [Wu et al., 2011], as special cases. Furthermore, in contrast to these tests, our proposed test has an added capacity to identify which components of variant characteristics and heterogeneity contribute to the association. Simulations under a wide range of scenarios show that the proposed test is valid, robust and powerful. An application to the Dallas Heart Study illustrates that apart from identifying genes with significant associations, the new method also provides additional information regarding the source of the association. Such information may be useful for generating hypothesis in future studies.

Elongational perturbations on nematic liquid crystal polymers under a weak shear  

NASA Astrophysics Data System (ADS)

The two-dimensional Smoluchowski equation is employed to study the effect of elongational perturbations on nematic liquid crystal polymers under a weak shear. We use the multiscale asymptotic analysis to show that (1) when the elongational perturbation is small relative to the weak shear, the orientational probability density function (pdf) tumbles periodically only in an intermediate range of polymer concentration; outside this intermediate range (i.e., for very small and very large polymer concentration) the orientational pdf converges to a steady state and there is no tumbling. (2) When the elongational perturbation is about 20% of the shear rate or larger, the intermediate range of tumbling disappears and the orientational pdf always converges to a steady state regardless of the polymer concentration. Our theoretical predictions are consistent with various earlier results based on the Leslie-Ericksen theory [C. V. Chaubal and L. G. Leal, J. Non-Newtonian Fluid Mech. 82, 22 (1999)] or analogous 3D numerical simulations [M. G. Forest, R. Zhou, and Q. Wang, Phys. Rev. Lett. 93, 088301 (2004); M. G. Forest, Q. Wang, R. Zhou, and E.

Stability of the shape of a translating viscoelastic drop at low Reynolds number  

NASA Astrophysics Data System (ADS)

We examine the stability of the shape of a viscoelastic drop translating in an immiscible, otherwise quiescent Newtonian fluid at low Reynolds number. Non-Newtonian stresses in the drop phase are characterized by the finitely extensible nonlinear elastic-Chilcott-Rallison model. A boundary integral method is used to numerically examine the time-evolution of initially perturbed drop shapes over a range of dimensionless parameters. For sufficiently small capillary numbers, the drop achieves an oblate spheroidal steady shape. For large initial deformations or capillary numbers, however, the drop deforms continuously and eventually breaks up through either the formation of an elongated tail or the development of a re-entrant cavity at its trailing end. These mechanisms of drop breakup are qualitatively similar to those reported earlier for Newtonian drops [C. J. Koh and L. G. Leal, Phys. Fluids A 1, 1309 (1989); C. Pozrikidis, J. Fluid Mech. 210, 1 (1990); H. A. Stone, Annu. Rev. Fluid Mech. 26, 65 (1994)]. Compared to the case of a Newtonian drop, drop phase elasticity is found to have a stabilizing (destabilizing) effect for initially oblate (prolate) shape perturbations, due to the development of polymeric stresses caused by deformation of polymer chains in alignment with streamlines of the flow. Polymer viscosity has a strong influence on the stability of the shape of drops, whereas polymer relaxation time and extensibility have relatively weak influences.

A comparison of methods to determine the onset of the growing season in northern Nigeria  

NASA Astrophysics Data System (ADS)

In the sudan savanna of northern Nigeria, with its semi-arid climate, the ability to determine effectively or predict the start of actual productive rains cannot be overemphasized. Several methods exist for calculating the date of onset of the rains that may be taken as the start of the growing season. Five methods currently in use, which are relatively easy to apply on a large scale, were selected for comparison. One is a traditional technique (Ramadan method), two use accumulated rainfall totals (Walter's and Sivakumar's methods), and two use rainfall-evapotranspiration relationships (Kowal's and Benoit's methods). For the period 1961-91, the traditional technique performed most poorly. Walter's method gave quite early onsets and Sivakumar's method gave very late onsets, thereby seriously shortening the growing season. Kowal's and Benoit's determinations fell most often in between the results of Walter's and Sivakumar's methods in their performance. However, although generally to a lesser extent than the other methods, they are still significantly affected by false starts. To avoid incorrectly predicting the growing season's onset as far as possible, but to prevent an unacceptable shortening of the growing season, a combination of Kowal's and Sivakumar's criteria was used to develop an improved technique. This proved to work well for determining the onset date in the study area. However, because some false starts remain when using average onset dates, it is suggested that an operational advisory team should be constituted by the government. This team would be responsible for calculating onset dates in any year, on-line for the ongoing season, in a participatory approach with farmers, and for disseminating such dates to the farmers. This could be done for any place for which the appropriate data can be made available. In the future, improved climate prediction skill may replace the classical probabilistic approaches presently suffering from increasing rainfall variabilities.

Perceptions of selected science careers by African American high school males  

NASA Astrophysics Data System (ADS)

Research indicates that internal and external factors such as role models, stereotypes, and pressures placed on African American males by their family and friends influence their perceptions of science careers (Assibey-Mensah, 1997; Hess & Leal, 1997; Jacobowitz, 1983; Maple & Stage, 1991; Thomas, 1989; Ware & Lee, 1988). The purpose of this research was to investigate the perceptions of African American high school males about selected science careers based on apparent internal and external factors. Two questions guided this research: (1) What are high school African American males' perceptions of science careers? (2) What influences high school African American males' perceptions of science careers? This research was based on a pilot study in which African American college males perceived a selection of science careers along racial and gender lines. The follow-up investigation was conducted at Rockriver High School in Acorn County, and the participants were three college-bound African American males. The decision to choose males was based on the concept of occupational niching along gender lines. In biology, niching is defined as the role of a particular species regarding space and reproduction, and its interactions with other factors. During the seven-week period of the students' senior year, they met with the researcher to discuss their perceptions of science careers. An ethnographic approach was used to allow a richer and thicker narrative to occur. Critical theory was used to describe and interpret the voices of the participants from a social perspective. The data collected were analyzed using a constant comparative analysis technique. The participants revealed role models, negative stereotypes, peer pressure, social pressures, and misconceptions as some of the factors that influenced their perceptions of science careers. Results of this research suggest that by dispelling the misconceptions, educators can positively influence the attitudes and perceptions of their students about science careers and possibly increase the number of African American men as well as other minorities currently underrepresented in some science careers.

A study of shear banding in polymer solutions  

NASA Astrophysics Data System (ADS)

In a recent letter [M. Cromer, M. C. Villet, G. H. Fredrickson, and L. G. Leal, "Shear banding in polymer solutions," Phys. Fluids 25, 051703 (2013)], we showed the existence of a steady shear-banded velocity profile for a model polymer solution with an underlying monotonic constitutive curve. The driving mechanism is the coupling of the polymer stress to an inhomogeneous concentration profile. To further understand this phenomenon, in this paper we investigate the underlying linear instability as well as probe the model parameters and their effect on transient and steady state solutions. The linear stability analysis of the steady, base homogeneous model shows that, in opposition to diffusion, the polymer concentration moves up stress gradients in a shear flow creating a critical balance such that, for a range of parameters, an instability occurs that drives the system away from homogeneity. The simulation of the full nonlinear equations in planar one-dimensional shear reveals a window within which the linear instability manifests itself as a shear-banded flow. Unlike the case for a nonmonotonic constitutive curve for which two bands are predicted, there is no apparent selection process for a monotonic curve that sets the number of bands in planar shear. Thus, we find the possibility of greater than two bands, the number of which is determined by the ratio of the polymer correlation length to the channel width. In addition to steady shear banding, transient phenomena are also probed revealing a complicated band transition (i.e., number of bands changing in time) as well as elastic recoil in a Taylor-Couette cell, each of which have been observed in experiment. Finally, as we showed in our letter, a nonlinear subcritical instability exists resulting in multiple steady states depending upon the wall ramp speed. Here, we show that this phenomenon can occur for realistic parameter values, in particular those obtained for a particular polymer solution that has shown this multiple steady state behavior experimentally.

A note on a linearized approach to gravitational lensing  

NASA Astrophysics Data System (ADS)

A recent paper by Walters, Forbes and Jarvis presented new kinematic formulae for ray tracing in gravitational lensing models. The approach can generate caustic maps, but is computationally expensive. Here, a linearized approximation to that formulation is presented. Although still complicated, the linearized equations admit a remarkable closed-form solution. As a result, linearized approximations to the caustic patterns may be generated extremely rapidly, and are found to be in good agreement with the results of full non-linear computation. The usual Einstein-angle approximation is derived as a small angle approximation to the solution presented here.

Walter Kraus, Alfred Gisel, and Werner Platzer, who worked directly or indirectly with Pernkopf, were interviewed in 2006. We present transcripts of those interviews. The reader may evaluate their recollections in light of the political and social forces active in that period of history. PMID:22927139

Theoretical basis of the linear nodal and linear characteristic methods in the TORT computer code  

SciTech Connect

Novel numerical procedures for solving the Boltzmann equation have been added to the Three Dimensional Oak Ridge Discrete Ordinates Transport Code (TORT). These procedures produce much more accuracy in theflux solutions for a given mesh size, or allow a smaller mesh to be used in order to reduce costs. The first method is a special adaptation of the linear nodal method proposed by Walters and O'Dell. The basic method has been extensively adapted in order to avoid numerical distortions that may occur in shielding problems. The second method is a characteristic procedure with linear expansion of sources and boundary flows. These methods are in widespread use in the TORT code.

Water Resources Research supports water economics submissions  

NASA Astrophysics Data System (ADS)

AGU's international interdisciplinary journal Water Resources Research (WRR) publishes original contributions in hydrology; the physical, chemical, and biological sciences; and the social and policy sciences, including economics, systems analysis, sociology, and law. With the rising relevance of water economics and related social sciences, the editors of WRR continue to encourage submissions on economics and policy. WRR was originally founded in the mid 1960s by Walter Langbein and economist Allen Kneese. Several former WRR editors have been economists—including David Brookshire, Ron Cummings, and Chuck Howe—and many landmark articles in water economics have been published in WRR.

A Teacher's Perspective: What Is Equity in Science Education?  

NSDL National Science Digital Library

In his essay, "What is Equity in Science Education?," page 167, Walter Secada challenges our understanding of equity by raising questions about how different meanings of equity can influence science education for English language learners. He highlights various perceptions of equity that he has encountered in schools--caring, socially enlightened self-interest, social justice, equality, representation, and opposition to excellence--and how these can motivate instructional decision-making and policy. Mary Rizzuto, a science curriculum instructional specialist for the Needham Public Schools in Needham, Massachusetts, shares her perspective.

Correlation of stability to varied CdCl2 treatment and related defects in CdS/CdTe PV devices as measured by thermal admittance spectroscopy  

NASA Astrophysics Data System (ADS)

A correlation between the CdCl2 treatment and the change in conversion efficiency with light and heat stress indoors (stability) has been shown previously by our group for CdS/CdTe:Cu PV devices. In the present work CdTe devices were fabricated with various CdCl2 treatments and with and without a Cu containing back contact. The electrical characteristics of the defects acting as traps in these devices were studied using thermal admittance spectroscopy (TAS). The activation energy Et-EV, the apparent capture cross section and the densities of state functions (using Walter's method) of the traps in the devices were estimated.

Fragment embolization is a rare phenomenon in trauma patients. Although surgical and endovascular management of vascular injuries have evolved significantly, the detection and management of fragment emboli remain a formidable challenge. We reviewed our experience with this entity from December 2001 to March 2008. During this time period, four (1.1%) of 346 US soldiers evacuated to Walter Reed with arterial or venous injuries were discovered to have suffered missile emboli. Venous emboli were treated with anticoagulation and arterial emboli were treated with standard embolectomy techniques with good result. The presentation, diagnosis, and surgical management of these cases are described. PMID:19703749

Independent-particle models of the nucleus in the 1930s  

NASA Astrophysics Data System (ADS)

In the early 1930s physicists developed two competing ways of describing the structure of the nucleus. One of these, the liquid-drop model as articulated by Niels Bohr, was widely regarded as preferable to Walter Elsasser's shell model, and became the accepted nuclear model by the end of the decade. According to the conventional history of nuclear physics, independent-particle models like Elsasser's were only revived 10 years later with the nuclear shell model of Mayer and Jensen. Throughout the period when they claimed to reject the view of nucleons as independent particles, however, nuclear physicists continued to treat nucleons mathematically as independent particles in order to calculate energy levels.

Increased levels of serum intercellular adhesion molecule 1 in HIV infection are related to immune activation.  

PubMed

Cytopathic mechanisms in human immunodeficiency virus type 1 (HIV-1) infection involve syncytia formation, and it appears likely that increased expression of intracellular adhesion molecule 1 (ICAM-1) is involved in these cell adhesion phenomena. In this study, we determined serum concentrations of soluble ICAM-1 (sICAM-1) in 27 patients with HIV-1 infection and a control group. In addition, we compared sICAM-1 values to CD4+ T-cell counts, serum beta 2-microglobulin (beta 2M) and serum neopterin levels. HIV-1-infected patients had significantly higher sICAM-1, beta 2M and neopterin levels than controls. The subgroup of patients with Walter-Reed stages 3-6 had only slightly higher sICAM-1 concentrations in serum than Walter-Reed stages 1-2. The sICAM-1 concentrations in HIV-1-seropositive patients correlated with beta 2M levels but neither with neopterin nor with CD4+ T-cell counts. Increased sICAM-1 may result from immune activation, which enhances the expression of ICAM-1 in patients with HIV-1 infection. PMID:8104576

Multi-site evaluation of a computer aided detection (CAD) algorithm for small acute intra-cranial hemorrhage and development of a stand-alone CAD system ready for deployment in a clinical environment  

NASA Astrophysics Data System (ADS)

Timely detection of Acute Intra-cranial Hemorrhage (AIH) in an emergency environment is essential for the triage of patients suffering from Traumatic Brain Injury. Moreover, the small size of lesions and lack of experience on the reader's part could lead to difficulties in the detection of AIH. A CT based CAD algorithm for the detection of AIH has been developed in order to improve upon the current standard of identification and treatment of AIH. A retrospective analysis of the algorithm has already been carried out with 135 AIH CT studies with 135 matched normal head CT studies from the Los Angeles County General Hospital/ University of Southern California Hospital System (LAC/USC). In the next step, AIH studies have been collected from Walter Reed Army Medical Center, and are currently being processed using the AIH CAD system as part of implementing a multi-site assessment and evaluation of the performance of the algorithm. The sensitivity and specificity numbers from the Walter Reed study will be compared with the numbers from the LAC/USC study to determine if there are differences in the presentation and detection due to the difference in the nature of trauma between the two sites. Simultaneously, a stand-alone system with a user friendly GUI has been developed to facilitate implementation in a clinical setting.

Starting and stopping basal sliding on ice streams: New insights from Whillans Ice Plain, West Antarctica  

NASA Astrophysics Data System (ADS)

The bidaily speed-up events of the Whillans Ice Plain, West Antarctica, provide a unique glimpse into glacier basal mechanics. Our results locate the slip initiation south of Ice Raft A, closer to the grounding line and the southernmost extent of the Ross Ice Shelf. The initiation may be controlled by a discontinuity in basal boundary conditions at the suture between two ice streams. A strong correlation between the amplitude of seismic waves generated at the rupture front and the total slip achieved over the duration of the slip event (~ 30 min) suggests slip-predictable behavior, i.e., the ability to forecast the eventual slip based on the first minute of seismic radiation. Successive slip events propagate with different rupture speeds (100-300 m/s) that strongly correlate with the inter-event duration, suggestive of a healing mechanism. The basal stress conditions currently promote freezing during inter-event periods and melting during the speed-up events. We update the results of Walter et al. (2011) with new insights from data collected in the 2010/11 field season, as well as examination of archived far-field seismic data from the last decade. Walter, J. I., E. E. Brodsky, S. Tulaczyk, S.

The third aldo castaneda lecture: the neglect of neonatal/infant cardiac disease in Africa--continental genocide?  

PubMed

The advances made in pediatric cardiology and cardiac surgery now make it possible for survival into adulthood of the majority of children born with congenitally malformed hearts. On the African continent, unfortunately, this is only a dream as roughly 280,000 neonates born every year on the continent are left untreated, demonstrating the natural history of the congenitally malformed heart by default. Pediatric cardiac surgery is available in very few countries on this continent. This article takes a look at the problem of neonates and infants born with cardiac defects on the continent and attempts an extrapolation of the magnitude of the problem. Using the experience gained at the Walter Sisulu Pediatric Cardiac Center since its inception in 2003, issues of financing indigent patients, training local personnel, and building capacity through infrastructure development and regional cooperation are discussed. The success of the Walter Sisulu model demonstrates the benefits of treatment for the neonates and infants with congenitally malformed heart, on the continent. It is emphasized that African governments and all stakeholders must participate to ensure a good outcome for the African child with congenital cardiac defect. PMID:23804781

Late-summer food of red-winged blackbirds in a fresh tidal-river marsh  

USGS Publications Warehouse

During late summer in the Delaware Valley and Chesapeake Bay region, hundreds of thousands of Red-winged Blackbirds feed in wild rice beds of fresh tidal-river marshes. The period during which wild rice seed is available coincides with the ripening period of a part of the corn crop, and there is evidence to indicate that the availability of the wild rice reduces bird feeding pressure on corn in the area. The importance of wild rice and other marsh plants to the redwing during the period when wild rice seed is available was studied further by field observations and by analysis of stomach contents of 130 birds collected in wild rice beds of the Patuxent River in southern Maryland.

Photoexcitation and Predissociation Intensities of N2 Singlet States  

NASA Astrophysics Data System (ADS)

Direct determinations of the intensity of photoexcitation followed by predissociation and the branching between predissociation and photoemission for rovibrational levels of excited states of N2 have been made. Laser excitation of a 3 keV beam of N2 is used with identification of the dissociation fragments by a position- and time-sensitive detector.(C.W. Walter, P.C. Cosby, H. Helm, J. Chem. Phys.) 99, 3553 (1993).^,(C.W. Walter, P.C. Cosby, H. Helm, Phys. Rev. A) 50, 2930 (1994). The states probed are b'^1? _u^+ (v=9-18), c'^1? _u^+ (v=3,4), c^1? u (v=3,4), e'^1? _u^+ (v=0), e^1? u (v=0), and o^1? u (v=3,4). Substantial predissociation is observed in each state, and dramatic variations in transition intensity are observed in some vibrational bands. The experimental results are compared with a perturbation model of the mixing between the valence and Rydberg states.(H. Helm, I. Hazell, N. Bjerre, Phys. Rev. A) 48, 2762 (1993). The model reproduces many of the observed perturbations and reveals that b' character is the dominant factor in the transition strength for these states. This model extends to levels of N2 beyond the experimental range, including the atmospherically important c' (v=0) state.

Gas-cooled reactor power systems for space  

SciTech Connect

In this paper the characteristics of six designs for power levels of 2, 10, and 20 MWe for operating times of 1 and 7 y are described. The operating conditions for these arbitrary designs were chosen to minimize system specific mass. The designs are based on recent work which benefits from earlier analyses of nuclear space power systems conducted at our Laboratory. Both gas- and liquid-cooled reactors had been considered. Pitts and Walter (1970) reported on the results of a detailed study of a 10-MWe lithium-cooled reactor in a potassium Rankine system. Unpublished results (1966) of a computer analysis provide details of an argon-cooled reactor in an argon Brayton system. The gas-cooled reactor design was based on extensive development work on the 500-MWth reactor for the nuclear ramjet (Pluto) as described by Walter (1964). The designs discussed here draw heavily on the Pluto project experience, which culminated in a successful full-power ground test as reported by Reynolds (1964). At higher power levels gas-cooled reactors coupled with Brayton systems with advanced radiator designs become attractive.

Heuristics for the transposition distance problem.  

PubMed

Transpositions are large-scale mutational events that occur when a block of genes moves from a region of a chromosome to another region within the same chromosome. The transposition distance problem is the minimum number of transpositions required to transform one genome into another. Recently, Bulteau et al. [Bulteau L, Fertin G, Rusu U, Automata, Languages and Programming, Vol. 6755 of Lecture Notes in Computer Science, pp. 654-665, Springer Berlin, Heidelberg, 2011] proved that finding the transposition distance is a NP-Hard problem. Some approximation algorithm for this problem have been presented to date [Bafna V, Pevzner PA, SIAM J Discr Math11(2):224-240, 1998; Elias I, Hartman T, IEEE/ACM Trans Comput Biol Bioinform3(4):369-379, 2006; Mira CVG, Dias Z, Santos HP, Pinto GA, Walter ME, Proc 3rd Brazilian Symp Bioinformatics (BSB'2008), pp. 115-126, Santo André, Brazil, 2008; Walter MEMT, Dias Z, Meidanis J, Proc String Processing and Information Retrieval (SPIRE'2000), pp. 199-208, Coruña, Spain, 2000]. Here we focus on developing heuristics to provide an improved approximated solution. Our approach outperforms other algorithms on small sized permutations. We also show that our algorithm keeps the good performance on longer permutations. PMID:24131057

Numerical study for the electrified instability of viscoelastic cylindrical dielectric fluid film surrounded by a conducting gas  

NASA Astrophysics Data System (ADS)

The linear electrohydrodynamic cylindrical instability of annular Walters B? viscoelastic dielectric fluid layer surrounded by a conducting gas in the presence of radial electric field is investigated. The obtained dispersion relation is found to be complicated and cannot be treated theoretically easily. Two limiting cases of interest are investigated, when the inertia is dominant, and when both the kinematic viscosity and viscoelasticity are high, and the corresponding new stability conditions are obtained for both cases. We solve the eigenvalue problem numerically using the continuation method which gives better results than the classical non-linear solvers such as Newton and Secant methods. It is found that the applied radial electric field has a dual role on the stability of the considered system, depending of the chosen wavenumbers range. Both the kinematic viscoelasticity and liquid depth are found to have stabilizing effects, while both the kinematic viscosity and surface tension have destabilizing effects on the considered system. The stability or instability breaks down for critical wavenumber values at which the growth rate vanishes. The behaviors of both the maximum growth rate and the corresponding dominant wavenumber are discussed in detail corresponding to the effect of all physical parameters. Finally a comparison between the results obtained here for Walters B? viscoelastic fluids, and those obtained here too if the fluid is replaced by a Rivlin-Ericksen viscoelastic one is achieved. The limiting cases of absence of electric field and/or kinematic viscoelasticity are also investigated in detail.

Earthquake Apparent Stress Scaling for the 1999 Hector Mine Sequence  

NASA Astrophysics Data System (ADS)

There is currently a disagreement within the geophysical community on the way earthquake energy scales with magnitude. One set of studies finds evidence that energy release per seismic moment (apparent stress) is constant (e.g. Choy and Boatwright, 1995; McGarr, 1999; Ide and Beroza, 2001). Other studies find the apparent stress increases with magnitude (e.g. Kanamori et al., 1993; Abercrombie, 1995; Mayeda and Walter, 1996; Izutani and Kanamori, 2001). The resolution of this issue is complicated by the difficulty of accurately accounting for attenuation, radiation inhomogeneities, bandwidth and determining the seismic energy radiated by earthquakes over a wide range of event sizes in a consistent manner. We try to improve upon earlier results by using consistent techniques over common paths for a wide range of sizes and seismic phases. We have examined about 130 earthquakes from the Hector Mine earthquake sequence in Southern California. These earthquakes range in size from the October 16,1999 Mw=7.1 mainshock down to ML=3.0 aftershocks into 2000. The mainshock has unclipped Pg and Lg phases at a number of high quality regional stations (e.g. CMB, ELK, TUC) where we can use the common path to examine apparent stress scaling relations directly. We are careful to avoid any event selection bias that would be related to apparent stress values. We fix each stations path correction using the independent moment and energy estimates for the mainshock. We then use those corrections to determine the seismic energy for each event based on regional Lg spectra. We use a modeling technique (MDAC) based on a modified Brune (1970) spectral shape but without any assumptions of corner-frequency scaling (Walter and Taylor, 2002). We perform similar analysis using the Pg spectra. We find the energy estimates for the same events are consistent for Lg estimates, Pg estimates and the estimates using the independent regional coda envelope technique (Mayeda and Walter, 1996; Mayeda et al, 2003). So far the results show the seismic energy to moment values or apparent stress increases with moment similar to our 1996 study. We plan to perform similar studies for other Southern California earthquake sequences. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under Contract No. W-7405-Eng-48.

Influence of surface water/groundwater interactions on stream and wetland water quality: analytical solutions for coupled contaminant transport equations  

NASA Astrophysics Data System (ADS)

Wetlands are located in transitional zones between uplands and downstream flooded systems and surface water/groundwater interactions are frequently observed especially in riparian wetlands where the water level fluctuates frequently during the rainy season. Moreover, surface water/groundwater interactions also influence the characteristics of contaminant transport in pools and riffles, and in meandering type of streams. Therefore, it is important to investigate and solve these processes accurately to improve the prediction of downstream water quality. Although there are many experimental and numerical studies available in the literature which discuss and model the surface water/ground water interactions in streams and wetlands, very few analytical solutions have been conducted. Analytical solutions are helpful tools for verification of numerical solutions and they provide fast and accurate results for practical problems. Furthermore, they provide an understanding to the influence of each parameter in hydrological and contaminant transport models for streams and wetlands. In order to contribute to the research in understanding the behavior of water quality in streams and wetlands, analytical solutions are developed for the coupled contaminant transport equations of several transient storage and wetland models. Among these models are the wetland model WETland Solute TrANsport Dynamics (WETSAND) developed by Kazezyilmaz-Alhan et al. (2007), the transient storage models developed by Bencala and Walters (1983), and Kazezyilmaz-Alhan and Medina (2006). WETSAND is a general comprehensive wetland model, which has both surface flow and solute transport components. In this wetland model, water quality components are solved by advection-dispersion-reaction equations which incorporate surface water/groundwater interactions by including the incoming/outgoing mass due to the groundwater recharge/discharge. The transient storage model developed by Bencala and Walters (1983) solves the contaminant distribution between main streams and stagnant zones. The transient storage is represented by the mass exchange due to the concentration difference between the stream and the storage zone in this model. The transient storage model developed by Kazezyilmaz-Alhan and Medina (2006) involves several improvements to the transient storage model of Bencala and Walters (1983): advection and dispersion processes are incorporated into the contaminant transport in hyporheic zone and the mass transport between the channel and hyporheic zone is represented by mass flux terms. The solutions of the governing equations are obtained for continuous source type of boundary conditions. Results show that analytical solutions are in good agreement with the numerical solutions.

A test of systematic coarse-graining of molecular dynamics simulations: Transport properties  

NASA Astrophysics Data System (ADS)

To what extent can a ``bottom-up'' mesoscale fluid model developed through systematic coarse-graining techniques recover the physical properties of a molecular scale system? In a previous paper [C.-C. Fu, P. M. Kulkarni, M. S. Shell, and L. G. Leal, J. Chem. Phys. 137, 164106 (2012)], we addressed this question for thermodynamic properties through the development of coarse-grained (CG) fluid models using modified iterative Boltzmann inversion methods that reproduce correct pair structure and pressure. In the present work we focus on the dynamic behavior. Unlike the radial distribution function and the pressure, dynamical properties such as the self-diffusion coefficient and viscosity in a CG model cannot be matched during coarse-graining by modifying the pair interaction. Instead, removed degrees of freedom require a modification of the equations of motion to simulate their implicit effects on dynamics. A simple but approximate approach is to introduce a friction coefficient, ?, and random forces for the remaining degrees of freedom, in which case ? becomes an additional parameter in the coarse-grained model that can be tuned. We consider the non-Galilean-invariant Langevin and the Galilean-invariant dissipative particle dynamics (DPD) thermostats with CG systems in which we can systematically tune the fraction ? of removed degrees of freedom. Between these two choices, only DPD allows both the viscosity and diffusivity to match a reference Lennard-Jones liquid with a single value of ? for each degree of coarse-graining ?. This friction constant is robust to the pressure correction imposed on the effective CG potential, increases approximately linearly with ?, and also depends on the interaction cutoff length, rcut, of the pair interaction potential. Importantly, we show that the diffusion constant and viscosity are constrained by a simple scaling law that leads to a specific choice of DPD friction coefficient for a given degree of coarse-graining. Moreover, we find that the pair interaction distance cutoffs used for DPD random and dissipative forces should be considered separately from that of the conservative interaction potential.

Assessment of Changes in Blocking Activity Over Southeastern Brazil Under Climate Change Scenarios  

NASA Astrophysics Data System (ADS)

One of the main current efforts of the climate community is to investigate the impact of projected global climate change scenarios upon atmospheric circulations on the regional scale. Projections of rainfall anomalies represent a key aspect for assessing regional impacts of climate change on important human activities such as the civil defense, agriculture, and power generation. Given the points above, the present research aims at assessing possible alterations associated with distinct climate change scenarios in the regime of one atmospheric processes that influence the precipitation distribution and modulation over southeastern Brazil: atmospheric blocking. Objectives The objectives are determine an updated climatology of blocking activity over southeastern Brazil, which will serve as the current state of the atmosphere regarding these two weather systems over the region of interest and to evaluate the modification in the frequency and/or strength blocking system in southeastern Brazil given distinct projected climate change scenarios, and to examine how this modification may affect the frequency of heavy rain and drought events in that region; Data The data to be used include for updating the current climatology of blocking: three-dimensional daily atmospheric fields obtained from the NCEP/NCAR Reanalysis (Kalnay et al. 1996) and meteorological fields obtained from distinct climate change scenarios made available by the IPCC. To update the climatology of blocking, objective criteria are necessary to detect (and track) such systems from the NCEP/NCAR Reanalysis data for southeastern South America. For blocking systems, anomalies in the 500hPa geopotential heights will be used, following Tibaldi et al. (1994) and Nascimento and Ambrizzi (2002) approach. References Douglas, M. W., and J. C.

PREHISTORICAL Pediculus humanus capitis INFESTATION: QUANTITATIVE DATA AND LOW VACUUM SCANNING MICROSCOPY  

PubMed Central

A pre-Columbian Peruvian scalp was examined decades ago by a researcher from the Oswaldo Cruz Foundation. Professor Olympio da Fonseca Filho described nits and adult lice attached to hair shafts and commented about the origin of head lice infestations on mankind. This same scalp was sent to our laboratory and is the subject of the present paper. Analysis showed a massive infestation with nine eggs/cm2 and an impressive number of very well preserved adult lice. The infestation age was roughly estimated as nine months before death based on the distance of nits from the hair root and the medium rate of hair growth. A small traditional textile was associated with the scalp, possibly part of the funerary belongings. Other morphological aspects visualized by low-vacuum scanning electron microscopy are also presented here for adults and nits.

The Two-Dimensional Euler Equations on Singular Domains  

NASA Astrophysics Data System (ADS)

We establish the existence of global weak solutions of the two-dimensional incompressible Euler equations for a large class of non-smooth open sets. Loosely, these open sets are the complements (in a simply connected domain) of a finite number of obstacles with positive Sobolev capacity. Existence of weak solutions with L p vorticity is deduced from a property of domain continuity for the Euler equations that relates to the so-called ?-convergence of open sets. Our results complete those obtained for convex domains in Taylor (Progress in Nonlinear Differential Equations and their Applications, Vol. 42, 2000), or for domains with asymptotically small holes (I ftimie et al. in Commun Partial Differ Equ 28(1-2), 349-379, 2003; Lopes Filho in SIAM J Math Anal 39(2), 422-436, 2007).

I present a harmonic decomposition analysis of the grand-design spiral galaxy NGC 628 using the H I data from The H I Nearby Galaxy Survey (THINGS), Walter et al., Astron. J. 136, 2563 (2008). The harmonic decomposition analysis allows the estimation of the peculiar motion magnitude of the galaxy not counted in the rotation of the disk. The rotation curve is obtained through a tilted ring analysis and reaches a maximum velocity not higher than 200 km s-1. The residual from the velocity field shows a morphology shift from a m = 1 to a m = 3 feature at R = 120", typical of two spiral arms perturbation of the potential. The non-circular motion have a magnitude of ~10 km s-1, in agreement with previous studies of similar Hubble type galaxies.

Meeting the patients where they are: consultation-liaison response to trauma victims of the Pentagon attack.  

PubMed

The Psychiatry Consultation-Liaison Service at Walter Reed Army Medical Center provided an immediate mental health response to hospitalized victims of the Pentagon attack on September 11. This article reviews our experience with this population and the lessons learned. Successful intervention required a flexible and innovative approach that included export of our services to the patient's location, liaison with involved facilities and treatment teams, and modification of therapeutic contact. Our debriefing approach was adapted to accommodate the victims' vulnerable psychological state in the wake of the trauma. Clinically effective interventions were implemented with the goals of reducing psychological symptoms, facilitating compliance with medical care, supporting rapid recovery of social and occupational functioning, and integrating social supports. This unique method, which we call "therapeutic debriefing," can serve as a model for future interventions after catastrophic events. PMID:12363131
