    O'Neil, K.

    As the world's largest fully steerable single dish telescope, the Robert C. Byrd Green Bank Telescope (GBT) has exceptional sensitivity from 100MHz through 100GHz. To exploit this sensitivity and to ensure the telescope remains at the forefront of science and technology, the GBT has an ongoing development program to provide new instrumentation and infrastructure improvements for the telescope. Here I describe the current state of the GBT as well as the ongoing and future development projects and challenges for the telescope. These include focal plane arrays at 30 and 90GHz, a phased (beam-forming) array at 1GHz, affordable wide-bandwidth digital data transmission lines, state of the art FPGA-based signal processing, very low noise receivers, and image processing of TB data sets.

  3. Observations of free-free and anomalous microwave emission from LDN 1622 with the 100 m Green Bank Telescope

    LDN 1622 has previously been identified as a possible strong source of dust-correlated anomalous microwave emission (AME). Previous observations were limited by resolution meaning that the radio emission could not be compared with current generation high-resolution infrared data from Herschel, Spitzer or Wide-field Infrared Sky Explorer. This paper presents arcminute resolution mapping observations of LDN 1622 at 4.85 and 13.7 GHz using the 100 m Robert C. Byrd Green Bank Telescope. The 4.85 GHz map reveals a corona of free-free emission enclosing LDN 1622 that traces the photodissociation region of the cloud. The brightest peaks of the 4.85 GHz map are found to be within ≈10 per cent agreement with the expected free-free predicted by Southern H-Alpha Sky Survey Atlas H α data of LDN 1622. At 13.7 GHz, the AME flux density was found to be 7.0 ± 1.4 mJy and evidence is presented for a rising spectrum between 13.7 and 31 GHz. The spinning dust model of AME is found to naturally account for the flux seen at 13.7 GHz. Correlations between the diffuse 13.7 GHz emission and the diffuse mid-infrared emission are used to further demonstrate that the emission originating from LDN 1622 at 13.7 GHz is described by the spinning dust model.

    The Green Bank Telescope The 100-m NRAO Green Bank Telescope will be completed in early 2000. The GBT has a large number of unique design and performance features that will give it unprecedented scientific capability. This poster display will review those features, which include an offset feed (clear aperture) design, an active surface, a closed-loop laser metrology system for surface figure and pointing control, broad frequency coverage from 100 MHz to 115 GHz, a versatile receiver selection mechanism, and a new multi-input, 256k-channel autocorrelation spectrometer. The status of the project, the commissioning schedule, plans for early operations, the initial instrumentation suite, and plans for future instrumentation will be reviewed. Scientific areas for which the GBT will have a large impact will be discussed, including observations of young galaxies at extreme redshifts, pulsars, HI and molecular spectroscopy, VLBI work, and millimeter-wave spectroscopy and continuum studies.

    The 100 m Green Bank Telescope will be completed in early 2000. The GBT is the most ambitious, single radio telescope ever constructed. It has a large number of unique design and performance features including an offset feed (clear aperture), an active surface, a closed-loop laser metrology system for surface figure and telescope pointing control, a feed turret for ready selection of numerous receivers, and a multi-input, 256k-channel spectrometer. The GBT will operate over a frequency range of 100 MHz to 115 GHz. The GBT and ALMA have great potential for complementary observations. The GBT will cover millimeter wavelengths longward of 2.6 mm and thus has a significant overlap with ALMA. The total physical collecting areas of 7854 m2 for the GBT and 7238 m2 for the 64x12-m ALMA configuration will give the facilities comparable flux sensitivities. The GBT has a wide field of view at its Gregorian focus that extends > 5 arcmin at 90 GHz with minimal aberrations. When equipped with focal plane array receivers, the GBT will be able to image large fields with high sensitivity very quickly. Such images will provide the astrophysical context of regions studied at high angular resolution with ALMA. The clean beam response and accurate absolute calibration of GBT data will make it ideal for combination with ALMA images. These, and other areas in which the GBT and ALMA will work in concert will be described in this poster.

  6. Construction Milestone Announced on Green Bank Telescope

    NASA Astrophysics Data System (ADS)

    2000-04-01

    The National Radio Astronomy Observatory announces completion of a major construction milestone on the world's largest fully steerable radio telescope - the National Science Foundation's Green Bank Telescope (GBT). The last of 2,004 aluminum surface panels was recently installed on the GBT's two-acre (100 m x 110 m) collecting dish. The telescope is located at NRAO's Green Bank site, in rural Pocahontas County, West Virginia. The GBT will be used to study everything from the formation of galaxies in the early universe, to the chemical make-up of the dust and gas inside galaxies and in the voids that separate them, to the birth processes of stars. In conjunction with other instruments, it will help make highly accurate radar maps of some familiar objects in our own solar system. The GBT is an engineering marvel. At 485 feet tall, it is comparable in height to the Washington Monument. It weighs 16 million pounds, yet by swiveling the dish in both azimuth and elevation, it can be pointed to any point in the sky with exquisite accuracy. Additionally, the telescope's two-acre collecting dish has many novel features. Most radio telescopes in use today use receivers suspended above the dish by four struts. These struts block some of the surface of the dish, scattering some of the incoming radio waves from celestial objects under study. The GBT's offset feedarm has no struts to block incoming radio waves. The GBT also boasts an active surface. The surface of the dish is composed of 2,004 panels. On the underside of the dish, actuators are located at each corner (i.e., intersection of four panels). These actuators are motors that move the surface panels up and down, keeping the (paraboloid) shape of the dish precisely adjusted, no matter what the tilt of the telescope. The combination of its unblocked aperture and active surface promise that the GBT will display extremely high sensitivity to faint radio signals. The GBT itself is not the only precious national resource in

    The National Radio Astronomy Observatory's Green Bank facility has several medium and large antennas that are available for satellite communications. The 100 meter Robert C. Byrd Green Bank Telescope (GBT), the largest and most sensitive antenna on site, is capable of receiving signals at frequencies as high as 86 GHz. In addition to the GBT are the fully operational 43 meter, 20 meter, and 13.7 meter antennas, and three mothballed 26 meter antennas. A transmitter could be fitted to any of these antennas for spacecraft uplinks. We discuss the characteristics of these antennas and possible operational models for future planetary science mission support.

    The Green Bank Telescope (GBT) is a 100-m diameter antenna with an unblocked aperture and an active surface. It is designed to observe at frequencies from 300 MHz to 100 GHz. Construction of the telescope is now in the final phase - installation of the surface panels - and will be completed in early 2000. The electronics systems for the telescope have been under development and testing in a "Mock-up" which includes the receivers, LO systems, analog filters, and the backends. Upon completion of construction, the telescope will undergo a series of commissioning procedures to prepare for general astronomical observing. We will illustrate the software tools being developed in support of the engineering tests and commissioning requirements of the GBT. These requirements include analysis of holography data, which will be used to measure the initial surface accuracy of the dish. This software is being developed in the AIPS++ programming environment using Glish, a powerful scripting language adopted by the AIPS++ system.

    The Green Bank Telescope (GBT) is a 100 meter diameter unblocked aperture radio telescope that will begin operations in the next year at the Green Bank, WV, Observatory of the NRAO. This presentation will describe some of the general categories of experiment that the GBT will be capable of doing, and illustrate its sensitivity and frequency coverage. The GBT will operate at frequencies from a few hundred MHz to about 100 GHz. This range encompasses quite a number of phenomenon, including: emission from pulsars; studies of HI in both galactic and highly redshifted systems; thermal and nonthermal emission from planets; molecules in comets, and planetary and stellar atmospheres; continuum emission from supernova remnants and normal galaxies; astrochemistry of heavy interstellar molecules; atomic and molecular spectroscopy of star-forming regions; redshifted CO and other molecules from the early universe, and continuum studies of highly redshifted dust. The GBT has an entirely new suite of receivers and detectors which will bring unprecedented sensitivity and sky coverage to many of these investigations. The telescope will be scheduled competitively, and we are interested in talking to anyone who plans to use it, so that the instrumental and software configuration can be the best possible match to planned projects. The NRAO is operated under a cooperative agreement with the National Science Foundation.

    2004-01-01

    Interstellar glycolaldehyde (CH20HCHO) has been detected with the 100-m Green Bank Telescope (GBT) toward the star-forming region Sagittarius B2(N) by means of the 1(sub 10)-1(sub 01),2(sub 11)-2(sub 02),3(sub 12)-3(sub 0), and 4(sub 13)-4(sub 04) rotational transitions at 13.48, 15.18, 17.98, and 22.14 GHz, respectively. An analysis of these four high signal- to-noise rotational transitions yields a glycolaldehyde state temperature of 8 K. Previously reported emission line detections of glycolaldehyde with the NRAO 12-m telescope at mm-wavelengths (71 GHz to 103 GHz) are characterized by a state temperature of -50 K. By comparison the GBT detections are surprisingly strong and seen in emission at 13.48 GHz, emission and absorption at 15.18 GHz, and absorption at 17.98 GHz and 22.14 GHz. We attribute the strong absorption observed by the GBT at the higher frequencies to the correspondingly smaller GBT beams coupling better to the continuum source(s) in Sagittarius B2(N). A possible model for the two-temperature regions of glycolaldehyde is discussed.

    2016-01-01

    The past several years have seen a tremendous advancement in our ability to characterize the structure of nearby molecular clouds and the substructures in which dense star-forming cores are born. These advances include identifying and classifying the young protostellar population (Spitzer c2d and Gould Belt surveys) and the dense cores and larger filaments and clumps which form the cores and YSOs (Herschel and JCMT Gould Belt Legacy Surveys). The power of these legacy surveys lies in the large areal coverage and consistency in observing strategies between nearby molecular clouds. A major gap in the present data is a comparable survey to characterize the dense gas properties. Kinematics and gas temperatures are key to understanding the history and future fate of star-forming material, and these are not accessible from the primarily continuum-based measurements in the legacy surveys described above. We have begun an ambitious legacy survey for the GBT, the Green Bank Ammonia Survey (GAS), to map NH3 emission toward all the northern Gould Belt star forming regions where Av > 7. The Gould Belt is a ring of young stars and star-forming regions that contains nearly all the ongoing, predominantly low-mass star formation within 500 pc of the Sun. Here we present the initial results from the survey.

    The NRAO-Green Bank Telescope is composed of a unique, versatile, and complex suite of instrumentation. Observers and staff members will require intuitive user interfaces that can exploit the full capabilities of the instrument. The object-oriented monitor and control system which underlies all of the GBT user interfaces provides a uniform software interface to each GBT device, from receivers to detectors. The control system allows the creation of high-level user interfaces in a wide range of programming languages with less effort than normally encountered in the creation of such interfaces. We will present at least two of the graphical user interfaces astronomers will encounter when observing with the GBT. One interface, written in Glish/Tk, is designed for astronomers and used for specifying observations. A demonstration will be given of another interface, written in Tcl/Tk, designed for the monitoring and debugging of telescope component and which will be used predominantly by telescope operators, engineers, and other staff members.

    Candidate designs for NRAO's 100-m clear-aperture radio telescope were evaluated and optimized by JPL using JPL-developed structural optimization and analysis software. The weight of a non-optimum design was reduced from 9.4 million pounds to 9.2 million pounds. The half-pathlength error due to gravity deformations was reduced from 0.041-inch rms to 0.034-inch rms.

  15. Newly Commissioned Green Bank Telescope Bags New Pulsars

    2002-01-01

    Astronomers using the National Science Foundation's newly commissioned Robert C. Byrd Green Bank Telescope (GBT) have discovered a windfall of three previously undetected millisecond pulsars in a dense cluster of stars in the Milky Way Galaxy. The Green Bank Telescope The Robert C. Byrd Green Bank Telescope "This globular cluster, known as Messier 62, has been very well studied, and it would have been an exciting discovery to find just one new pulsar. The fact that we were able to detect three new pulsars at one time is simply remarkable," said Bryan Jacoby, a graduate student at the California Institute of Technology who led the research team. Results of the discovery were recently announced in an International Astronomical Union Circular. Jacoby and his colleague Adam Chandler, also a graduate student at Caltech, used the GBT to search for new pulsars in addition to the three already known in this cluster. Their research was part of the GBT's Early Science Program, which allows scientific investigations during the testing and commissioning of the telescope. The researchers used the Berkeley-Caltech Pulsar Machine, a new instrument whose development was overseen by Donald Backer at the University of California at Berkeley, to process the signals from the GBT and record them for later analysis. After their data were analyzed, the researchers discovered the telltale signatures of three additional pulsars and their white dwarf companion stars. Pulsars are rapidly rotating neutron stars that emit intense beams of radio waves along their misaligned magnetic axes. When these beams intersect the Earth, we see the pulsar flash on and off. Due to their exquisitely steady rotation, pulsars allow astronomers to study the basic laws of physics and the ways in which these dense clusters and exotic stellar systems are formed. Astronomers study globular clusters because they are among the oldest building blocks of our Galaxy. With their very dense stellar populations, these

    This paper briefly summarizes the results of a computational study performed to evaluate the electrical performance of the Green Bank Telescope reflector antenna. All computed patterns were obtained with the program PRAC (Parabolic Reflector Analysis Code), developed by the authors, and with the commercial code GRASP7. The patterns and performance values, not published anywhere else as far as the authors know, indicate that low cross polarization (XPOL) performance can be achieved with a dual offset configuration, provided that a low XPOL feed is employed.

    The catalog yielded by the MIT-Green Bank 5-GHz survey contains 5974 sources with S/N ratio greater than 5; a supplemental catalog contains 3836 possible detections with S/N of less than 5. The reliability of the main list is measured to be about 96 percent, with a completeness of about 95 percent. Flux density errors are a function of flux density. A comparison is presently made of survey sources from the Douglas et al. (1980) 365-MHz Texas survey; spectral indices are computed for coincident sources, and the distribution of spectral indices is discussed.

    To use the 100-meter Green Bank Telescope at millimeter wavelengths, the antenna surface must be continuously adjusted to compensate for environmental effects. The metrology system, comprising a network of infrared laser rangers, has been developed to measure the position of the surface to an accuracy of 50 microns. The metrology computer control system is described here. The embedded systems which point the 18 lasers and take range measurements are based on Intel x86 computers. The central control of these computers is done using a Pentium PC running Windows NT. Engineering displays of the data are produced by piping the data in real-time to Microsoft Excel.

    The third MIT-Green Bank survey, which covers 1.11 sr in the right ascension range from 16.5 h to 5 h between +17 deg and +39.15 deg declination, is presented. The survey is unique in that a sample was observed twice in a short period of time and the spectral indices between 5 and 1.4 GHz are available for most of the sources brighter than 90 mJy. This survey can be used as the starting point for a search for gravitational lenses. The source list can also be examined for clustering and used to estimate the surface density of sources as a function of limiting flux density. 10 refs.

  1. Youngest Radio Pulsar Revealed with Green Bank Telescope

    NASA Astrophysics Data System (ADS)

    2002-04-01

    Astronomers using the National Science Foundation's (NSF) newly commissioned Robert C. Byrd Green Bank Telescope (GBT) have detected remarkably faint radio signals from an 820 year-old pulsar, making it the youngest radio-emitting pulsar known. This discovery pushes the boundaries of radio telescope sensitivity for discovering pulsars, and will enable scientists to conduct observations that could lead to a better understanding of how these stars evolve. The Robert C. Byrd Green Bank Telescope Robert C. Byrd Green Bank Telescope "Important questions about pulsars may be answered by long-term monitoring of objects such as the one we just detected," said Fernando Camilo of Columbia University in New York City. "Young pulsars are particularly rare, and being able to study such a young one at radio wavelengths provides an outstanding opportunity to learn critical facts about their evolution and workings." The results of this research, based on observations conducted on February 22-23, 2002, were accepted for publication in the Astrophysical Journal Letters. Scientists have long suspected that a pulsar - a rapidly spinning, superdense neutron star - was born when a giant star ended its life in a cataclysmic supernova explosion observed in late summer of 1181, as suggested by Japanese and Chinese historical records. For the past 20 years, astronomers have searched this supernova remnant (3C58), located 10,000 light-years away in the constellation Cassiopeia, for the telltale pulsations of a newly born pulsar. Late in 2001, data from NASA's Chandra X-ray satellite confirmed its existence, but it remained an elusive quarry for radio telescopes. "We believed from historical records and certainly knew from recent X-ray observations that this star was there," Camilo remarked, "but despite many attempts, no one had been able to find any radio pulsations from it because the signals are, it turns out, incredibly weak." For comparison, this pulsar's radio emission is some 250

    We describe a close-packed, two-dimensional imaging detector system for operation at 90GHz (3.3mm) for the 100 m Green Bank Telescope (GBT) This system will provide high sensitivity (<1mjy in 1s rapid imaging (15'x15' to 250 microJy in 1 hr) at the world's largest steerable aperture. The heart of this camera is an 8x8 close packed, Nyquist-sampled array of superconducting transition edge sensor bolometers. We have designed and are producing a functional superconducting bolometer array system using a monolithic planar architecture and high-speed multiplexed readout electronics. With an NEP of approx. 2.10(exp 17) W/square root Hz, the TES bolometers will provide fast linear sensitive response for high performance imaging. The detectors are read out by and 8x8 time domain SQUID multiplexer. A digital/analog electronics system has been designed to enable read out by SQUID multiplexers. First light for this instrument on the GBT is expected within a year.

    First light with the NRAO Green Bank Telescope was achieved on August 22 with observations at a frequency of 403 MHz of the extragalactic radio source 1140+223 and the pulsar PSR B1133+16. Outfitting of the telescope should be completed by the end of 2000 and commissioning is anticipated to start mid November 2000. The telescope should be capable of 50 GHz observations within one year and 100 GHz within two years. Limited scientific observing should start in the first quarter of 2001 -- the NRAO has issued a special call for proposals for experienced observers who are willing to perform observations in a commissioning environment. The NRAO will have additional calls for proposals from a wider audience as significant classes of new capabilities are commissioned. The GBT, due to its unprecedented design and start-of-the art receivers and backends, has unique scientific capabilities. The most distinguishing features include an offset geometry that provides a 100-m clear aperture, a closed-loop metrology system for maintaining surface accuracy and pointing, a mechanism for easily selecting receivers, a suite of receivers that cover from 100 MHz to eventually 115 GHz, and a new 256k-channel spectrometer. This paper describes the current status of commissioning the GBT, the unique features of the telescope, and the scientific areas in which the GBT will have a large impact.

    2010-08-01

    We discovered a large population of previously unknown Galactic H II regions by using the Green Bank Telescope to detect their hydrogen radio recombination line emission. Since recombination lines are optically thin at 3 cm wavelength, we can detect H II regions across the entire Galactic disk. Our targets were selected based on spatially coincident 24 μm and 21 cm continuum emission. For the Galactic zone -16 ° <= ell <= 67° and |b| <= 1°, we detected 602 discrete recombination line components from 448 lines of sight, 95% of the sample targets, which more than doubles the number of known H II regions in this part of the Milky Way. We found 25 new first quadrant nebulae with negative LSR velocities, placing them beyond the solar orbit. Because we can detect all nebulae inside the solar orbit that are ionized by O-stars, the Discovery Survey targets, when combined with existing H II region catalogs, give a more accurate census of Galactic H II regions and their properties. The distribution of H II regions across the Galactic disk shows strong, narrow (~1 kpc wide) peaks at Galactic radii of 4.3 and 6.0 kpc. The longitude-velocity distribution of H II regions now gives unambiguous evidence for Galactic structure, including the kinematic signatures of the radial peaks in the spatial distribution, a concentration of nebulae at the end of the Galactic Bar, and nebulae located on the kinematic locus of the 3 Kpc Arm.

    We discovered a large population of previously unknown Galactic HII regions by using the NRAO Green Bank Telescope to detect hydrogen radio recombination line (RRL) emission from these nebulae. Since recombination lines are optically thin at 3 cm wavelength, we can detect HII regions across the entire Galactic disk. Our targets were selected based on spatially coincident 24µm (Spitzer/MIPSGAL) and 21 cm (either from the VLA Galactic Plane Survey or the NRAO NVSS) continuum emission. For the Galactic zone, -16° < Lgal < 67° and |Bgal|<1°, we detected 602 discrete RRL components from 95% of the sample targets, which more than doubles the number of known HII regions in this part of the Milky Way. We found 25 new first quadrant nebulae with negative RRL velocities, placing them beyond the Solar orbit in the Perseus arm. We plan to determine the distance to over 90% of our sources (for the region Lgal>18°) by using HI emission/absorption experiments to resolve the kinematic distance ambiguity. Because we can detect all nebulae inside the Solar orbit that are ionized by O-stars, the Discovery Survey targets, when combined with existing HII region catalogs, will give a more accurate census of Galactic HII regions and their properties. The distribution of HII regions across the Galactic disk shows strong, narrow ( 1 kpc wide) peaks at Galactic radii of 4.3 and 6.0 kpc. There is still an overall dearth of HII regions within 4 kpc radius. For the first time the longitude-velocity distribution of HII regions gives unambiguous evidence for Galactic structure, including the kinematic signatures of the radial peaks in the spatial distribution, a concentration of nebulae at the end of the Galactic Bar, and nebulae located in kinematic locus of the 3 kpc Arm.

  7. Decision Announced in Green Bank Telescope Arbitration Case

    2001-02-01

    A decision has been reached by the arbitrator in the dispute between COMSAT Corporation, now part of Lockheed-Martin Global Telecommunications, and Associated Universities, Inc. (AUI) regarding additional costs on the contract to design and construct the Robert C. Byrd Green Bank Telescope (GBT). The GBT, in West Virginia, is the world's largest fully steerable radio telescope, the newest facility in the National Radio Astronomy Observatory's (NRAO) suite of astronomical instruments. The decision, released by the American Arbitration Association (AAA), calls for AUI, which operates the NRAO, to pay COMSAT 4.07 million over the fixed-price contract amount. The contract had standard provisions for disputes, which specify binding arbitration through the AAA for matters that could not be resolved in negotiation. The Robert C. Byrd Green Bank Telescope The contract to design and construct the GBT had an agreed fixed price of 55 million, with work to begin on December 19, 1990 and to be completed by the end of 1994. The contract terms required the telescope to be designed and built to performance specifications, placing most of the performance risks associated with the project on the contractor. The telescope was accepted from the contractor on October 13, 2000, nearly six years later than the original contract delivery date. During the entire period of contract work the only agreed change in scope was a single change order for 150,000 executed in August of 1993. In 1998, COMSAT sought an additional payment of approximately 29 million above the contracted amount, alleging that AUI/NRAO had forced it to conduct unnecessary work on the telescope design and to build the telescope to an unreasonable life cycle (fatigue) specification. COMSAT also claimed that AUI/NRAO was obligated to pay the costs of accommodating what it claimed to be additional wind loads. COMSAT blamed these circumstances for its delay in completing the project on time and within the contract price. AUI

    The 100 meter diameter Green Bank Telescope, with its large frequency coverage, great sensitivity, all-sky tracking, and location at a protected, radio-quiet site, offers a unique platform for technological advances in astronomical instrumentation that can yield an immediate scientific payoff.MUSTANG-1.5 is a feedhorn-coupled bolometer array for 3mm that has recently been installed on the telescope. It has 64 pixels (expandable to 223) and offers sensitivity to angular scales from 9" to more than 3' over a band from 75 GHz to 105 GHz. Its capabilities for science at 3mm are complimentary to, and in some cases superior to, those offered by ALMA. MUSTANG-1.5 is a collaboration between UPenn., NIST, NRAO, and other institutions.ARGUS is a 16-pixel focal plane array for millimeter spectroscopy that will be in use on the GBT in 2015. The array architecture is designed as a scalable technology pathfinder for larger arrays, but by itself it will provide major capabilities for spectroscopy from 75-107 GHz with 8" angular resolution over a wide field-of-view. It is a collaboration between Stanford Univ., Caltech, JPL, Univ. Maryland, Univ. Miami, and NRAO.FLAG is a prototype phased array receiver operating at 21cm wavelength that is under development for the GBT. It will produce multiple beams over a wide field of view with a sensitivity competitive with that of single-pixel receivers, allowing rapid astronomical surveys. FLAG is a collaboration between BYU, WVU, and NRAO.Also under development is a mm-wave phased array receiver for the GBT, designed to operate near 90 GHz as a prototype for very large format phased array receivers in the 3mm band. It is a collaboration between UMass and BYU.VEGAS is the new spectrometer for the GBT, offering multiple configurations well matched to GBT receivers from 1 to 100 GHz and suitable for use with focal plane arrays. It is a collaboration between UCal (Berkeley) and NRAO.The new receivers and spectrometers create extremely big data

    The paper reports neutral hydrogen observations of a large sample of dwarf and other low surface brightness galaxies. A detailed discussion and error analysis of the observations are presented, and spectra are displayed for 329 galaxies detected for the first time, or detected with substantially better signal-to-noise ratios than achieved previously. The positions on the sky of 667 galaxies meeting the present selection criteria north of delta = 38 deg are shown. The distribution of the redshifts of galaxies detected at Green Bank is illustrated. The Green Bank detections tapered off strongly below the median H I flux of 3.7 Jy km/s detected at Arecibo: only 12 percent of the Green Bank sample was detected with smaller fluxes.

    Smith's Cloud is a large few × 106 Solar Mass cloud which will impact the Milk Way disk in about 35 Million Years (Lockman et al., 2008). Green Bank Telescope OH observations indicate that there are no molecules present in Smith's Cloud, and thus there is no active ongoing chemistry in Smith's Cloud.

  11. "First Light" for the Newly Christened Robert C. Byrd Green Bank Telescope

    2000-08-01

    Strip Chart Recording of the Pulsar Signals Received During the Robert C. Byrd Green Bank Telescope's First Observation of a Celestial Radio Source At a ceremony last Friday (Aug. 25) in which the National Science Foundation's Green Bank Telescope (GBT) was formally dedicated, U.S. Senator Robert C. Byrd (D - WV) announced that the gigantic telescope had successfully opened its two-acre 'eye' on the Universe earlier that week. The telescope was christened the "Robert C. Byrd Green Bank Telescope" at the ceremony, which was held at the National Radio Astronomy Observatory (NRAO) site in Green Bank, West Virginia. The event also featured remarks from Dr. Rita R Colwell, Director of the National Science Foundation. First light details: The Robert C. Byrd Green Bank Telescope saw 'first light' (that is, detected its first radio waves from space) at 7:00 p.m. EDT, Tuesday, August 22, 2000. Earlier that day, a 403-megahertz radio-wave receiver had been installed on the telescope. In its first simple observation, the GBT tracked a radio galaxy called 1140+223 across the sky. The telescope then locked onto a pulsar called PSR B1133+16 and a chart recorder scratched out the regular pattern of its radio pulses, which reach Earth every 1 2 seconds. (A pulsar is a rotating neutron star that shines a beam of radio waves like a cosmic lighthouse; these radio pulses sweep across the Earth at regular intervals.) Dr. Mark McKinnon, Deputy Site Director at NRAO's Green Bank site, led the team that conducted the observations. "This first-light event is the most significant milestone in the construction of the GBT. It is the first step in commissioning this telescope," McKinnon said. "This shows that the receivers we built for the GBT work, and that the telescope is properly aligned. We have a working telescope." "The next phase is the telescope commissioning," McKinnon continued. "That means we measure the telescope's performance, and make detailed refinements of its pointing and

    Neutral hydrogen observations at 21cm, made at the Green Bank 91m telescope in 1984, 1985 and 1986, of a large sample of dwarf and other low surface brightness galaxies are presented. The majority of galaxies classified in the Uppsala General Catalogue as dwarf, irregular, Sdm, or later and with declinations north of the range of the Arecibo telescope (δ>38°) have been observed, along with a number of galaxies farther south for flux comparisons with Arecibo observations (Schneider et al., 1990ApJS...72..245S, Paper I), totaling over 600 galaxies. About half of these galaxies have no previously published detections. In total, counting previous detections, over 80% of these late-type systems are detected at Green Bank. We have examined the galaxies for potential confusion with nearby galaxies, and we also present substantially better signal-to-noise measurements for many previously detected galaxies. Some general results of the Green Bank survey are discussed here, but the total data base of northern dwarf and low surface brightness galaxies, including new measurements of the galaxies' photographic magnitudes, will be examined in subsequent papers.

    Massive green algae blooms became an environmental disaster in the Yellow Sea from 2008 to 2013. Recent studies suggested that recurrences of early aggregates of macroalgae were found over the Subei Bank, a unique shallow radial sand ridge system off the Jiangsu coast, China. Yearly field surveys have been carried out over this bank during the past five years (2009-2013), with an aim at identifying and qualifying the physical-biological mechanism for the early aggregation of algae. Data synthesis showed that early aggregation of macroalgae usually occurred from April-May as small-scale patches either over the intertidal mudflat of the Subei Bank or along local isobaths in the northern coastal area north of the bank. Both hydrographic and current measurements were performed by tracking a narrow patchy area of floating macroalgae (nearly 4 km in length and 5-10 m in width) on April 26, 2013, and the results showed that the algae aggregation was mainly caused by tide-induced convergence. This convergence was produced by the local geometrically controlled interaction of tidal currents with mudflats, which is believed to be a key physical mechanism for the early development of algal blooms in addition to marine ecosystem responses and human aquaculture activities.

    We describe an ongoing search for pulsars and dispersed pulses of radio emission, such as those from rotating radio transients (RRATs) and fast radio bursts, at 350 MHz using the Green Bank Telescope. With the Green Bank Ultimate Pulsar Processing Instrument, we record 100 MHz of bandwidth divided into 4096 channels every 81.92 μs. This survey will cover the entire sky visible to the Green Bank Telescope (δ > –40°, or 82% of the sky) and outside of the Galactic Plane will be sensitive enough to detect slow pulsars and low dispersion measure (<30 pc cm{sup –3}) millisecond pulsars (MSPs) with a 0.08 duty cycle down to 1.1 mJy. For pulsars with a spectral index of –1.6, we will be 2.5 times more sensitive than previous and ongoing surveys over much of our survey region. Here we describe the survey, the data analysis pipeline, initial discovery parameters for 62 pulsars, and timing solutions for 5 new pulsars. PSR J0214+5222 is an MSP in a long-period (512 days) orbit and has an optical counterpart identified in archival data. PSR J0636+5129 is an MSP in a very short-period (96 minutes) orbit with a very low mass companion (8 M{sub J}). PSR J0645+5158 is an isolated MSP with a timing residual RMS of 500 ns and has been added to pulsar timing array experiments. PSR J1434+7257 is an isolated, intermediate-period pulsar that has been partially recycled. PSR J1816+4510 is an eclipsing MSP in a short-period orbit (8.7 hr) and may have recently completed its spin-up phase.

  15. New Book Recounts Exciting, Colorful History Of Radio Astronomy in Green Bank, West Virginia

    A new book published by the National Radio Astronomy Observatory (NRAO) tells the story of the founding and early years of the Observatory at Green Bank, West Virginia. But it was Fun: the first forty years of radio astronomy at Green Bank, is not a formal history, but rather a scrapbook of early memos, recollections, anecdotes and reports. But it was Fun... is liberally illustrated with archival photographs. It includes historical and scientific papers from symposia held in 1987 and 1995 to celebrate the birthdays of two of the radio telescopes at the Observatory. Book cover The National Radio Astronomy Observatory was formed in 1956 after the National Science Foundation decided to establish an observatory in the eastern United States for the study of faint radio signals from distant objects in the Universe. But it was Fun... reprints early memos from the group of scientists who searched the mountains for a suitable site -- an area free from radio transmitters and other sources of radio interference -- "in a valley surrounded by as many ranges of high mountains in as many directions as possible," which was "at least 50 miles distant from any city or other concentration of people." The committee settled on Green Bank, a small village in West Virginia, and the book documents the struggles that followed to create a world-class scientific facility in an isolated area more accustomed to cows than computers. Groundbreaking at the Observatory, then a patchwork of farms and fields, took place in October 1957, only a few days after the launch of Sputnik by the Soviet Union. A year later, Green Bank's first telescope was dedicated, and the book contains a transcription of speeches given at that ceremony, when the Cold War, the space race and America's scientific stature were issues of the hour. The centerpiece of the new Observatory was to be a highly-precise radio telescope 140 feet in diameter, but it was expected that it would soon be surpassed by dishes of much greater

    Recent UV absorption line studies suggest that a large fraction of missing baryons are in the warm ionized and neutral phases, with about half of Milky Way-mass galaxies containing absorption systems with HI column densities of 10^18 cm^-2 or greater. This HI gas, which would have been difficult to detect with previous instruments, could have enough mass to account for the missing baryons. The Green Bank Telescope (GBT) presents a unique opportunity to detect this emission. We present GBT results from a sample of ten nearby optically luminous spirals in search of these extended disks of low column density HI.

    To conduct astronomical observations during windy days and increase the time available for exploration with the Green Bank Telescope (GBT) it is necessary to reduce the sensitivity of the telescope structure to wind forces. A promising approach is to design an advanced robust control system for wind induced vibration attenuation. As a first step it is necessary to (1) model analytically the structure and the servo system of the telescope and (2) validate the model through systems identification experiments. This paper presents the results of the identification experiments of the structure and the servo system along with the subsequent interval analysis.

    MUSTANG 2 is a 223 element focal plane that operates between 75 and 105 GHz on the 100 meter Green Bank Telescope. It shares many of the science goals of its predecessor, MUSTANG, but will have fifteen times the sensitivity and five times the field-of-view. Angular scales from 900 to 60 will be recovered with high fidelity providing a unique overlap between high resolution instruments such as ALMA and lower resolution single dish telescopes such as ACT or SPT. Individual TES bolometers are placed behind feedhorns spaced by 1.9λ f and are read out using a microwave SQUID multiplexing system.

    The Green Bank Telescope is a large flexible structure, requiring rms tracking error ≤ 3 arcseconds against internal and external disturbances. We design an extended state observer (ESO) based controller in various configurations to improve tracking performance and increase disturbance rejection. The controllers are simulated with an experimentally validated model of the GBT. Through the simulations, the response of ESO based controllers and legacy PID controller are compared using time and frequency domain responses. We show that the ESO based controller when implemented in both position and velocity loop can give significant improvement in tracking performance and better disturbance rejection without increase in controller output.

    We have identified 21 millisecond pulsars (MSPs) in globular cluster Terzan 5 by using the Green Bank Telescope, bringing the total of known MSPs in Terzan 5 to 24. These discoveries confirm fundamental predictions of globular cluster and binary system evolution. Thirteen of the new MSPs are in binaries, of which two show eclipses and two have highly eccentric orbits. The relativistic periastron advance for the two eccentric systems indicates that at least one of these pulsars has a mass 1.68 times greater than the mass of the Sun at 95% confidence. Such large neutron star masses constrain the equation of state of matter at or beyond the nuclear equilibrium density.

    The NRAO Green Bank Telescope (GBT), located in Green Bank, West Virginia, is supported by 16 steel wheels which rest upon a composite steel and concrete Azimuth Track, 210 feet (64 meters) in diameter. From the start of observing in February 2001, the Azimuth Track design presented an operational problem for NRAO. By the spring of 2001, slippage of the top plate on the base plate was causing hold-down bolt failures. In July 2002, wear between the top and base plates (fretting) had become evident around the entire track circumference. NRAO engineers took immediate action to reduce both the track slippage and wear problems. But in January 2003, cracks were discovered in two adjacent top plates; by 2006 the top plates were cracking at a rate of almost one a month - an alarming rate given the design service life of 20 years. This paper will summarize the engineering analysis efforts that were subsequently conducted to assess the root cause of the GBT track degradation problem. We will also discuss a trial modification section that was installed in June 2004. Finally, we will discuss the design solution that was developed to remedy the track performance problem.

  4. Development of an EtherCAT enabled digital servo controller for the Green Bank Telescope

    2012-09-01

    EtherCAT (Ethernet for Control Automation Technology) is gaining wide spread popularity in the automation industry as a real time field bus based on low cost, Ethernet hardware. EtherCAT maximizes use of 100Mbps Ethernet hardware by using a collision free ring topology, efficient Ethernet frame utilization (> 95%), and data exchange "on the fly". These characteristics enable EtherCAT to achieve Master to Slave node data exchange rates of > 1000 Hz. The Green Bank Telescope, commissioned in 2000, utilizes an analog control system for motion control of 8 elevation and 16 azimuth motors. This architecture, while sufficient for observations at frequencies up to 50GHz, has significant limitations for the current scientific goals of observing at 115GHz. Accordingly, the Green Bank staff has embarked on a servo upgrade project to develop a digital servo system which accommodates development and implementation of advanced control algorithms. This paper describes how the new control system requirements, use of existing infrastructure and budget constraints led us to define a distributed motion control architecture where EtherCAT real-time Ethernet was selected as the communication bus. Finally, design details are provided that describe how NRAO developed a custom EtherCAT-enabled motor controller interface for the GBT's legacy motor drives in order to provide technical benefits and flexibility not available in commercial products.

    2013-12-20

    We present results from a study of 12 X-ray bright clusters at 1.4 GHz with the 100 m Green Bank Telescope. After subtraction of point sources using existing interferometer data, we reach a median (best) 1σ rms sensitivity level of 0.01 (0.006) μJy arcsec{sup –2}, and find a significant excess of diffuse, low surface brightness emission in 11 of 12 Abell clusters observed. We also present initial results at 1.4 GHz of A2319 from the Very Large Array. In particular, we find: (1) four new detections of diffuse structures tentatively classified as two halos (A2065, A2069) and two relics (A2067, A2073); (2) the first detection of the radio halo in A2061 at 1.4 GHz, which qualifies this as a possible ultra-steep spectrum halo source with a synchrotron spectral index of α ∼ 1.8 between 327 MHz and 1.4 GHz; (3) a ∼2 Mpc radio halo in the sloshing, minor-merger cluster A2142; (4) a >2× increase of the giant radio halo extent and luminosity in the merging cluster A2319; (5) a ∼7× increase to the integrated radio flux and >4× increase to the observed extent of the peripheral radio relic in A1367 to ∼600 kpc, which we also observe to be polarized on a similar scale; (6) significant excess emission of ambiguous nature in three clusters with embedded tailed radio galaxies (A119, A400, A3744). Our radio halo detections agree with the well-known X-ray/radio luminosity correlation, but they are larger and fainter than current radio power correlation studies would predict. The corresponding volume-averaged synchrotron emissivities are 1-2 orders of magnitude below the characteristic value found in previous studies. Some of the halo-like detections may be some type of previously unseen, low surface brightness radio halo or blend of unresolved shock structures and sub-Mpc-scale turbulent regions associated with their respective cluster merging activity. Four of the five tentative halos contain one or more X-ray cold fronts, suggesting a possible connection between gas

    Terada, Marco A. B.; Stutzman, Warren L.

    1998-03-01

    This paper presents an evaluation of the electrical performance of the Green Bank Telescope (GBT) reflector antenna, operating as single- and dual-offset configurations, as well as a general overview of the GBT system. The GBT dual-offset Gregorian configuration is designed for low cross polarization (XPOL) using the dual-offset reflector antenna (DORA) synthesis package code. The procedure implemented in DORA to upgrade an existing main reflector to a low cross-polarized dual-offset Gregorian reflector antenna is also described. All computed patterns were obtained with the parabolic reflector analysis code (PRAC) program, and with the commercial code GRASP7. The GBT radiation patterns and performance values indicate that low XPOL performance can be achieved with a dual-offset configuration, provided that a low XPOL feed is used. The GBT configuration is employed as a case example for the aforementioned procedure.

    2015-01-01

    Feedback processes such as large-scale galactic winds are thought to be responsible for distributing enriched gas throughout a galaxy and even into the IGM. Such winds have been found in many galaxies with active star formation near their center, and the Fermi bubbles provide evidence for such a nuclear wind in our own Milky Way. A recent 21 cm HI survey by the Australia Telescope Compact Array discovered a population of compact, isolated clouds surrounding the Galactic Center that may be entrained in the Fermi bubble wind. We present data from a survey of 21cm HI over an extended region around the Galactic Center using the Green Bank Telescope. These observations provide more strict constraints on neutral clouds in the Fermi bubble wind, and a more robust description of the parameters of HI clouds (i.e., mass, column density, and lifetime) near the Galactic Center.

    NGC 1976 (Orion A) is the best studied HII region in the Milky Way and therefore it is often used to test models of HII regions. In particular, the radial dependence of the electron temperature is able to distinguish between different models. Optical determinations of electron temperature in the outer regions are affected by scattered light from the center. We have observed the radio recombination line (RRL) and continuum emission near 5 GHz at 4 arc minutes East, West and South of the peak HII region emission in NGC 1976 using the Green Bank Telescope (GBT). The Full Width to Half Power at the observing frequency, 5 GHz, was 2 arc minutes. The result is that the average electron temperature for these offset positions is = 7200 ± 300 K, significantly lower than the electron temperature of the peak position = 8200 ± 300 K, consistent with the HII region model of Wilson et al. (2012).

    Ford, H. Alyson; Bregman, Joel N.

    Recent UV absorption line studies suggest that a large fraction of missing baryons are in the warm ionized and neutral phases, with about half of Milky Way-mass galaxies containing absorption systems with HI column densities of 1018 cm-2 or greater. This HI gas, which would have been difficult to detect with previous instruments, could be a significant contributor to the missing baryons. The Green Bank Telescope (GBT) presents a unique opportunity to detect this emission. We present results from GBT 21 cm observations of a sample of ten nearby optically luminous spirals, which reveal extended HI gas in half of our sample. The column densities of this extended HI are typically ~ 1 × 1019 cm-2, as measured at distances of 100 kpc from the center of the galaxies.

    This paper outlines an anti-cogging methodology and summarizes the current state of motor cogging cancellation on the Green Bank Telescope (GBT). An iterative, model-based algorithm is developed for finding the anticogging signal which yields rapid convergence. This method fills a gap in present methodologies in that it can serve as a drop-in cogging solution which operates in the presence of unknown structural dynamics as well as with an existing feedback controller. The algorithm is described and demonstrated on a 40 HP DC brushed motor test bed and also on the GBT's elevation axis motors. Results and implementation experience from deploying the algorithm on a motor test bed and on the GBT are discussed.

    We report on polarimetric observations of 100 pulsars centered on 774 MHz, made using the Green Bank Telescope, presenting their polarization profiles and polarized flux densities and comparing them with previous observations when possible. For 67 pulsars, these are the first such measurements made. Polarization profiles of 8 millisecond-pulsars in our sample show wide profiles and flat position-angle curves. Strong linear polarization, sometimes approaching 100% of the total intensity, has been detected in all or a part of the average pulse profiles of some pulsars. In general, circular polarization is very weak, although it is observed to be extremely strong in the leading component of PSR J1920+2650. Sense reversal of circular polarization as a function of pulse phase has been detected from both core and other components of more than 20 pulsars. Any relationship between the spin-down luminosity and the percentage of linear polarization is not evident in our data at this frequency.

    We report on the development of Argus, a 16-pixel spectrometer, which will enable fast astronomical imaging over the 85-116 GHz band. Each pixel includes a compact heterodyne receiver module, which integrates two InP MMIC low-noise amplifiers, a coupled-line bandpass filter and a sub-harmonic Schottky diode mixer. The receiver signals are routed to and from the multi-chip MMIC modules with multilayer high frequency printed circuit boards, which includes LO splitters and IF amplifiers. Microstrip lines on flexible circuitry are used to transport signals between temperature stages. The spectrometer frontend is designed to be scalable, so that the array design can be reconfigured for future instruments with hundreds of pixels. Argus is scheduled to be commissioned at the Robert C. Byrd Green Bank Telescope in late 2014. Preliminary data for the first Argus pixels are presented.

    The California Institute of Technology and the National Radio Astronomy Observatory have constructed a new continuum backend for use with the 26 to 40 GHz pseudo-correlation receiver on the Green Bank Telescope (GBT). The backend simultaneously measures RF power across the full 14 GHz receiver band in two feeds and two polarizations, and is capable of executing a rapid beam switch to suppress the effects of receiver gain fluctuations. Combined with the GBT's large and excellent surface the CCB will give unprecedented cm-wave sensitivity to study CMB discrete-source foregrounds and very small-scale anisotropies. We present an overview of the instrument and our early science program, which aims to more precisely measure the small-scale excess power seen by the Cosmic Background Imager.

    We are building Argus, a 16-pixel square-packed focal plane array that will cover the 75-115.3 GHz frequency range on the Robert C. Byrd Green Bank Telescope (GBT). The primary research area for Argus is the study of star formation within our Galaxy and nearby galaxies. Argus will map key molecules that trace star formation, including carbon monoxide (CO) and hydrogen cyanide (HCN). An additional key science area is astrochemistry, which will be addressed by observing complex molecules in the interstellar medium, and the study of formation of solar systems, which will be addressed by identifying dense pre-stellar cores and by observing comets in our solar system. Argus has a highly scalable architecture and will be a technology path finder for larger arrays. The array is modular in construction, which will allow easy replacement of malfunctioning and poorly performing components.

    We are using the Green Bank Telescope to make 21-cm intensity maps of cosmic structure in a 0.15 Gpc^3 box at redshift of z 1. The intensity mapping technique combines the flux from many galaxies in each pixel, allowing much greater mapping speed than the traditional redshift survey. Measurement is being made at z 1 to take advantage of a window in frequency around 700 MHz where terrestrial radio frequency interference (RFI) is currently at a minimum. This minimum is due to a reallocation of this frequency band from analog television to wide area wireless internet and public service usage. We will report progress of our attempt to detect autocorrelation of the 21-cm signal. The ultimate goal of this mapping is to use Baryon Acoustic Oscillations to provide more precise constraints to dark energy models.

    The NSF-funded "Research Experience for Teachers" project provides teachers an opportunity to work on a current scientific or engineering research project. This paper will present the results of research conducted with the Robert C. Byrd Green Bank Telescope (GBT) as well as classroom activities that will use GBT data. In order to determine the accuracy of the calibration of receivers on cm-wave radio telescopes, engineers must periodically determine the equivalent temperature of a receiver's calibration noise diode. The traditional methods utilize hot-cold loads and usually achieve an accuracy of no better than 5%, have a very coarse frequency resolution, and require days of labor. Using observations with the GBT of standard astronomical flux calibrators, we measured the noise diode temperatures for four receivers that cover 1 to 10 GHz. By comparing the detected power from the calibrators to that generated by the noise diodes we were able to determine the temperature of the noise diodes to an accuracy of 1% with very good frequency resolution (1 MHz). The astronomically determined values agree, with few exceptions, to the less accurate values generated by the receiver engineer. In contrast to the methods employed by engineers, the astronomical determinations took only a few hours. Using data collected from the GBT and the NRAO 140-foot telescope, high-school students at Breck School in Golden Valley, MN will use the Hands-On Universe (HOU) software to analyze fits files containing data from a 100 square-degree region of the Orion Nebula. Instead of always relying on optical images from personal observations or the HOU groups at Lawrence Hall of Science or Yerkes, students can now use radio images. Comparing radio images with those derived at optical wavelengths should prove enlightening for students, many of whom have misconceptions concerning radio astronomy.

    Sprint mechanics and field 100-m performances were tested in 13 subjects including 9 non-specialists, 3 French national-level sprinters and a world-class sprinter, to further study the mechanical factors associated with sprint performance. 6-s sprints performed on an instrumented treadmill allowed continuous recording of step kinematics, ground reaction forces (GRF), and belt velocity and computation of mechanical power output and linear force-velocity relationships. An index of the force application technique was computed as the slope of the linear relationship between the decrease in the ratio of horizontal-to-resultant GRF and the increase in velocity. Mechanical power output was positively correlated to mean 100-m speed (P < 0.01), as was the theoretical maximal velocity production capability (P < 0.011), whereas the theoretical maximal force production capability was not. The ability to apply the resultant force backward during acceleration was positively correlated to 100-m performance (r (s) > 0.683; P < 0.018), but the magnitude of resultant force was not (P = 0.16). Step frequency, contact and swing time were significantly correlated to acceleration and 100-m performance (positively for the former, negatively for the two latter, all P < 0.05), whereas aerial time and step length were not (all P > 0.21). Last, anthropometric data of body mass index and lower-limb-to-height ratio showed no significant correlation with 100-m performance. We concluded that the main mechanical determinants of 100-m performance were (1) a "velocity-oriented" force-velocity profile, likely explained by (2) a higher ability to apply the resultant GRF vector with a forward orientation over the acceleration, and (3) a higher step frequency resulting from a shorter contact time.

    Electrical and optical performance data are presented for a prototype 100 mK spider-web bolometer operating under very low photon backgrounds. These data are compared with the bolometer theory and are used to estimate the expected sensitivity of such a detector used for low background space astronomy. The results demonstrate that the sensitivity and speed of response requirements of the bolometer instruments proposed for these missions can be met by 100 mK spider-web bolometers using neutron transmutation doped germanium as the temperature sensitive element.

    A 400 Gbps/100 m free-space optical (FSO) link with dense-wavelength-division-multiplexing (DWDM)/space-division-multiplexing (SDM) techniques and a doublet lens scheme is proposed. To the best of our knowledge, this is the first time that a link adopting DWDM and SDM techniques and a doublet lens scheme has demonstrated a 400 Gbps/100 m FSO link. The experimental results show that the free-space transmission rate is significantly enhanced by the DWDM and SDM techniques, and the free-space transmission distance is greatly increased by the doublet lens scheme. A 16-channel FSO link with a total transmission rate of 400 Gbps (25 Gbps/λ  ×  16 λ  =  400 Gbps) over a 100 m free-space link is successfully demonstrated. Such a 400 Gbps/100 m DWDM/SDM FSO link provides the advantages of optical wireless communications for high transmission rates and long transmission distances, which is very useful for high-speed and long-haul light-based WiFi (LiFi) applications.

    We report the discovery with the 100m Green Bank Telescope of 65 ms radio pulsations from the X-ray pulsar J0205+6449 at the center of supernova remnant 3C58, making this possibly the youngest radio pulsar known. From our observations at frequencies of 820 and 1375 MHz, the free electron column density to USSR J0205+6449 is found to be 140.7 +/- 0.3/cc pc. The barycentric pulsar period P and P(dot) determined from a phase-coherent timing solution are consistent with the values previously measured from X-ray observations. The averaged radio profile of USSR J0205+6449 consists of one sharp pulse of width = 3 ms = 0.05 P. The pulsar is an exceedingly weak radio source, with pulse-averaged flux density in the 1400 MHz band of approximately 45 micro-Jy and a spectral index of approximately -2.1. Its radio luminosity of approximately 0.5 may kpc(exp 2) at 1400 MHz is lower than that of approximately 99% of known pulsar and is the lowest among known young pulsars.

    The purpose of this investigation was to compare and determine the relevance of the morphological characteristics and variability of running speed parameters (stride length and stride frequency) between Usain Bolt’s three best 100 m performances. Based on this, an attempt was made to define which factors determine the performance of Usain Bolt’s sprint and, therefore, distinguish him from other sprinters. We analyzed the previous world record of 9.69 s set in the 2008 Beijing Olympics, the current record of 9.58 s set in the 2009 Berlin World Championships in Athletics and the O lympic record of 9.63 s set in 2012 London Olympics Games by Usain Bolt. The application of VirtualDub Programme allowed the acquisition of basic kinematical variables such as step length and step frequency parameters of 100 m sprint from video footage provided by NBC TV station, BBC TV station. This data was compared with other data available on the web and data published by the Scientific Research Project Office responsible on behalf of IAAF and the German Athletics Association (DVL). The main hypothesis was that the step length is the main factor that determines running speed in the 10 and 20 m sections of the entire 100 m distance. Bolt’s anthropometric advantage (body height, leg length and liner body) is not questionable and it is one of the factors that makes him faster than the rest of the finalists from each three competitions. Additionally, Bolt’s 20 cm longer stride shows benefit in the latter part of the race. Despite these factors, he is probably able to strike the ground more forcefully than rest of sprinters, relative to their body mass, therefore, he might maximize his time on the ground and to exert the same force over this period of time. This ability, combined with longer stride allows him to create very high running speed - over 12 m/s (12.05 – 12.34 m/s) in some 10 m sections of his three 100 m performances. These assumption confirmed the application of

    We present the methodology for 'blind' millimeter-wave surveys for redshifted molecular absorption in the CO/HCO{sup +} rotational lines. The frequency range 30-50 GHz appears optimal for such surveys, providing sensitivity to absorbers at z ≳ 0.85. It is critical that the survey is 'blind', i.e., based on a radio-selected sample, including sources without known redshifts. We also report results from the first large survey of this kind, using the Q-band receiver on the Green Bank Telescope (GBT) to search for molecular absorption toward 36 sources, 3 without known redshifts, over the frequency range 39.6-49.5 GHz. The GBT survey has a total redshift path of Δz ≈ 24, mostly at 0.81 < z < 1.91, and a sensitivity sufficient to detect equivalent H{sub 2} column densities ≳ 3 × 10{sup 21} cm{sup –2} in absorption at 5σ significance (using CO-to-H{sub 2} and HCO{sup +}-to-H{sub 2} conversion factors of the Milky Way). The survey yielded no confirmed detections of molecular absorption, yielding the 2σ upper limit n(z = 1.2) < 0.15 on the redshift number density of molecular gas at column densities N(H{sub 2}) ≳ 3 × 10{sup 21} cm{sup –2}.

    The Green Bank Telescope H II Region Discovery Survey (GBT HRDS) found hundreds of previously unknown Galactic regions of massive star formation by detecting hydrogen radio recombination line (RRL) emission from candidate H II region targets. Since the HRDS nebulae lie at large distances from the Sun, they are located in previously unprobed zones of the Galactic disk. Here, we derive the properties of helium and carbon RRL emission from HRDS nebulae. Our target sample is the subset of the HRDS that has visible helium or carbon RRLs. This criterion gives a total of 84 velocity components (14% of the HRDS) with helium emission and 52 (9%) with carbon emission. For our highest quality sources, the average {sup 4}He{sup +}/H{sup +} abundance ratio by number, (y {sup +}), is 0.068 {+-} 0.023(1{sigma}). This is the same ratio as that measured for the sample of previously known Galactic H II regions. Nebulae without detected helium emission give robust y {sup +} upper limits. There are 5 RRL emission components with y {sup +} less than 0.04 and another 12 with upper limits below this value. These H II regions must have either a very low {sup 4}He abundance or contain a significant amount of neutral helium. The HRDS has 20 nebulae with carbon RRL emission but no helium emission at its sensitivity level. There is no correlation between the carbon RRL parameters and the 8 {mu}m mid-infrared morphology of these nebulae.

    Polarization leakage of foreground synchrotron emission is a critical issue in H i intensity mapping experiments. While the sought-after H i emission is unpolarized, polarized foregrounds such as Galactic and extragalactic synchrotron radiation, if coupled with instrumental impurity, can mimic or overwhelm the H i signals. In this paper, we present the methodology for polarization calibration at 700-900 MHz, applied on data obtained from the Green Bank Telescope (GBT). We use astrophysical sources, both polarized and unpolarized sources including quasars and pulsars, as calibrators to characterize the polarization leakage and control systematic effects in our GBT H i intensity mapping project. The resulting fractional errors on polarization measurements on boresight are well controlled to within 0.6%-0.8% of their total intensity. The polarized beam patterns are measured by performing spider scans across both polarized quasars and pulsars. A dominant Stokes I to V leakage feature and secondary features of Stokes I to Q and I to U leakages in the 700-900 MHz frequency range are identified. These characterizations are important for separating foreground polarization leakage from the H i 21 cm signal.

    2015-10-01

    Various forms of measurement errors limit telescope tracking performance in practice. A new method for identifying the correcting coefficients for encoder interpolation error is developed. The algorithm corrects the encoder measurement by identifying a harmonic model of the system and using that model to compute the necessary correction parameters. The approach improves upon others by explicitly modeling the unknown dynamics of the structure and controller and by not requiring a separate system identification to be performed. Experience gained from pin-pointing the source of encoder error on the Green Bank Radio Telescope (GBT) is presented. Several tell-tale indicators of encoder error are discussed. Experimental data from the telescope, tested with two different encoders, are presented. Demonstration of the identification methodology on the GBT as well as details of its implementation are discussed. A root mean square tracking error reduction from 0.68 arc seconds to 0.21 arc sec was achieved by changing encoders and was further reduced to 0.10 arc sec with the calibration algorithm. In particular, the ubiquity of this error source is shown and how, by careful correction, it is possible to go beyond the advertised accuracy of an encoder.

    To understand the cosmic histories of star formation and accretion, observers must determine the redshifts of distant galaxies whose central starbursts and/or active nuclei are heavily obscured by dust. Direct spectroscopy of molecular emission lines is the ideal way to meet this challenge, but a suitable instrument must have large instantaneous bandwidth to achieve broad redshift coverage. We describe a new, ultra-wideband "Zpectrometer" now under construction for the Green Bank Telescope that satisfies this need. Using a novel analog lag cross-correlator spectrometer technology in a correlation radiometer architecture, the Zpectrometer will produce stable spectra over the entire 26-40 GHz range of the GBT's Ka-band receiver. The Zpectrometer will enable blind searches for CO(1-0) emission in the redshift range where the cosmic star formation rate density peaks, higher-J CO transitions at earlier epochs, and rotational lines from other molecules at a variety of redshifts. This project is funded by a National Science Foundation ATI Program grant to the University of Maryland and by contributions from the National Radio Astronomy Observatory.

    The goal of this study was to examine the relationship between kinematics, motor abilities, anthropometric characteristics, and the initial (10 m) and secondary (30 m) acceleration phases of the 100 m sprint among athletes of different sprinting performances. Eleven competitive male sprinters (10.96 s ± 0.36 for 100 with 10.50 s fastest time) and 11 active students (12.20 s ± 0.39 for 100 m with 11.80 s fastest time) volunteered to participate in this study. Sprinting performance (10 m, 30 m, and 100 m from the block start), strength (back squat, back extension), and jumping ability (standing long jump, standing five-jumps, and standing ten-jumps) were tested. An independent t-test for establishing differences between two groups of athletes was used. The Spearman ranking correlation coefficient was computed to verify the association between variables. Additionally, the Ward method of hierarchical cluster analysis was applied. The recorded times of the 10 and 30 m indicated that the strongest correlations were found between a 1-repetition maximum back squat, a standing long jump, standing five jumps, standing ten jumps (r = 0.66, r = 0.72, r = 0.66, and r = 0.72), and speed in the 10 m sprint in competitive athletes. A strong correlation was also found between a 1-repetition maximum back squat and a standing long jump, standing five jumps, and standing ten jumps (r = 0.88, r = 0.87 and r = 0.85), but again only for sprinters. The most important factor for differences in maximum speed development during both the initial and secondary acceleration phase among the two sub-groups was the stride frequency (p<0.01).

    Using the H I emission/absorption method, we resolve the kinematic distance ambiguity and derive distances for 149 of 182 (82%) H II regions discovered by the Green Bank Telescope H II Region Discovery Survey (GBT HRDS). The HRDS is an X-band (9 GHz, 3 cm) GBT survey of 448 previously unknown H II regions in radio recombination line and radio continuum emission. Here, we focus on HRDS sources from 67 Degree-Sign {>=} l {>=} 18 Degree-Sign , where kinematic distances are more reliable. The 25 HRDS sources in this zone that have negative recombination line velocities are unambiguously beyond the orbit of the Sun, up to 20 kpc distant. They are the most distant H II regions yet discovered. We find that 61% of HRDS sources are located at the far distance, 31% at the tangent-point distance, and only 7% at the near distance. 'Bubble' H II regions are not preferentially located at the near distance (as was assumed previously) but average 10 kpc from the Sun. The HRDS nebulae, when combined with a large sample of H II regions with previously known distances, show evidence of spiral structure in two circular arc segments of mean Galactocentric radii of 4.25 and 6.0 kpc. We perform a thorough uncertainty analysis to analyze the effect of using different rotation curves, streaming motions, and a change to the solar circular rotation speed. The median distance uncertainty for our sample of H II regions is only 0.5 kpc, or 5%. This is significantly less than the median difference between the near and far kinematic distances, 6 kpc. The basic Galactic structure results are unchanged after considering these sources of uncertainty.

    Flux densities for 149 sources were monitored with the Green Bank Interferometer for durations ranging from 3 to 15 yrs, covering the interval 1979--1996, with most sources observed for 6 yrs. Observations were at two radio frequencies (approximately 2.5 and 8.2 GHz) and have a typical sampling of one flux density measurement every 2 days. We have used these light curves to conduct various variability analysis of the sources. We find suggestive, though not unambiguous evidence, that these sources have a common, broadband mechanism for intrinsic variations. We also find that the extrinsic variation is more consistent with radio-wave scattering in an extended medium rather than in a thin screen. The primary motivation for this monitoring program was the identification of extreme scattering events. In an effort to identify ESEs in a systematic manner, we have taken the wavelet transform of the light curves. We find 15 events in the light curves of 12 sources that we classify as probable ESEs. However, we also find that five ESEs previously identified from these data do not survive our wavelet selection criteria. Future identification of ESEs will probably continue to rely on both visual and systematic methods. We present examples of the light curves and variability analyses. Instructions for obtaining the data are also given.

    In both the Milky Way and nearby galaxies, the presence of dense molecular gas is correlated with recent star formation, suggesting that the formation of this gas may represent a key regulating step in the star formation process. Testing this idea requires wide-area, high-resolution maps of dense molecular gas in galaxies to explore how local physical conditions drive dense gas formation. Until now, these observations have been limited by the faintness of dense gas tracers like HCN and HCO+, but new instruments like the 4mm receiver on Robert C. Byrd Green Bank Telescope (GBT) -- the largest single-dish millimeter telescope -- are poised to change this picture. We present GBT maps of the dense gas tracers HCN and HCO+ in the prototypical nearby starburst galaxy M82. The HCN and HCO+ in the disk of M82 correlates both with recent star formation and the diffuse molecular gas and shows kinematics consistent with a rotating torus. HCO+ emission is also associated with the outflow of molecular gas previously identified in CO. These observations mark the first time that dense molecular gas like HCO+ has been associated with an outflow in a nearby galaxy and suggests that the outflow of dense molecular gas from the center of galaxies like M82 may regulate the star formation globally. Finally, the CO-to-HCN and CO-to-HCO+ line ratios reveal that there is more dense gas at the center of M82, pointing to the starburst as a key driver of this relationship. These results establish that the GBT can efficiently map the dense molecular gas at 90 GHz in nearby galaxies; this capability will increase further with the 16-element feed array currently being built for the GBT.

    We have completed sensitive searches for new pulsars in seven globular clusters using the Robert C. Byrd Green Bank Telescope, and have discovered six new recycled pulsars (four in NGC 6517 and two in M22), five of which are fully recycled millisecond pulsars with P < 10 ms. We report full timing solutions for all six new pulsars and provide estimates of their flux densities and spectral indices. None of the pulsars is detected in archival Chandra data down to L{sub X} {approx} 10{sup 32} erg s{sup -1} for NGC 6517 and L{sub X} {approx} 10{sup 31} erg s{sup -1} for M22. One of the millisecond pulsars in M22 appears to have a very low mass companion, and is likely a new 'black widow'. A second binary pulsar in NGC 6517 is in a long-period, mildly eccentric orbit. We are able to set some lower limits on the age of the system, and find that it may be less than a few hundred million years old, which would indicate recent pulsar recycling in NGC 6517. An isolated pulsar in NGC 6517 that lies about 20 core radii from the cluster center appears to have been ejected from the core by interacting with a massive binary. By analyzing the luminosity function of the pulsars in NGC 6517, we predict the cluster to harbor roughly a dozen pulsars. We use the observed period derivatives of three pulsars to set lower limits on the mass-to-light ratios in the cores of their host clusters, and find no evidence for large amounts of low-luminosity matter. We also discuss reasons for non-detections in some of the clusters we searched.

  14. Green bank telescope observations of low column density H I around NGC 2997 and NGC 6946

    Observations of ongoing H I accretion in nearby galaxies have only identified about 10% of the fuel necessary to sustain star formation in these galaxies. Most of these observations have been conducted using interferometers and may have missed lower column density, diffuse, H I gas that may trace the missing 90% of gas. Such gas may represent the so-called cold flows predicted by current theories of galaxy formation to have never been heated above the virial temperature of the dark matter halo. As a first attempt to identify such cold flows around nearby galaxies and complete the census of H I down to N {sub H} {sub I} ∼ 10{sup 18} cm{sup –2}, I used the Robert C. Byrd Green Bank Telescope (GBT) to map the circumgalactic (r ≲ 100-200 kpc) H I environment around NGC 2997 and NGC 6946. The resulting GBT observations cover a 4 deg{sup 2} area around each galaxy with a 5σ detection limit of N{sub H} {sub I} ∼ 10{sup 18} cm{sup –2} over a 20 km s{sup –1} line width. This project complements absorption line studies, which are well-suited to the regime of lower N{sub H} {sub I}. Around NGC 2997, the GBT H I data reveal an extended H I disk and all of its surrounding gas-rich satellite galaxies, but no filamentary features. Furthermore, the H I mass as measured with the GBT is only 7% higher than past interferometric measurements. After correcting for resolution differences, the H I extent of the galaxy is 23% larger at the N{sub H} {sub I} = 1.2 × 10{sup 18} cm{sup –2} level as measured by the GBT. On the other hand, the H I observations of NGC 6946 reveal a filamentary feature apparently connecting NGC 6946 with its nearest companions. This H I filament has N{sub H} {sub I} ∼ 5 × 10{sup 18} cm{sup –2} and an FWHM of 55 ± 5 km s{sup –1} and was invisible in past interferometer observations. The properties of this filament are broadly consistent with being a cold flow or debris from a past tidal interaction between NGC 6946 and its satellites.

    This paper introduces and describes the data cubes from GHIGLS, deep Green Bank Telescope (GBT) surveys of the 21 cm line emission of H i in 37 targeted fields at intermediate Galactic latitude. The GHIGLS fields together cover over 1000 deg2 at 9\\buildrel{ \\prime}\\over{.} 55 spatial resolution. The H i spectra have an effective velocity resolution of about 1.0 km s-1 and cover at least -450\\lt {v}{LSR}\\lt +250 km s-1, extending to {v}{LSR}\\lt +450 km s-1 for most fields. As illustrated with various visualizations of the H i data cubes, GHIGLS highlights that even at intermediate Galactic latitude the interstellar medium is very complex. Spatial structure of the H i is quantified through power spectra of maps of the integrated line emission or column density, {N}{{H} {{I}}}. For our featured representative field, centered on the north ecliptic pole, the scaling exponents in power-law representations of the power spectra of {N}{{H} {{I}}} maps for low-, intermediate-, and high-velocity gas components (LVC, IVC, and HVC) are -2.86+/- 0.04, -2.69+/- 0.04, and -2.59+/- 0.07, respectively. After Gaussian decomposition of the line profiles, {N}{{H} {{I}}} maps were also made corresponding to the narrow-line and broad-line components in the LVC range; for the narrow-line map the exponent is -1.9+/- 0.1, reflecting more small-scale structure in the cold neutral medium (CNM). There is evidence that filamentary structure in the H i CNM is oriented parallel to the Galactic magnetic field. The power spectrum analysis also offers insight into the various contributions to uncertainty in the data, yielding values close to those obtained using diagnostics developed in our earlier independent analysis. The effect of 21 cm line opacity on the GHIGLS {N}{{H} {{I}}} maps is estimated. Comparisons of the GBT data in a few of the GHIGLS fields with data from the EBHIS and GASS surveys explore potential issues in data reduction and calibration and reveal good agreement. The high

    This paper presents the design and current status of a K-Band Focal Plane Array (KFPA) for the Green Bank Telescope (GBT). The prototype array will go online with 7 independent dual-polarized beams, but the design target is a fully-populated instrument with approximately 60 beams on the sky. This project presents a number of technical challenges, including the architecture of a cryostat capable of supporting 60 independent receivers, design of high- performance components that fit behind the aperture of a compact feedhorn, and stable transmission of the large-volume of receiver data from the telescope to a remote building for back-end processing.

    Calibration for spectral line observations covering 68-92 GHz on the Green Bank Telescope uses a different calibration scheme than lower frequency receivers. In addition and extremely important is that any calibration scheme must not generate radio frequency interference (RFI) to other experiments ongoing at the Green Bank Observatory. An asynchronous logic network interfaces between the telescope control system, a brushless AC motor and three bit position encoding to place or remove reflectors, absorber or a quarter wave plate in the beam of the feeds to enable observers to calibrate their data during observations or configure the receiver for Very Long Baseline Interferometer network observations. This system is free of RFI that schemes utilizing more commonly available technology create.

    The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) has uncovered a population of strongly lensed submillimeter galaxies (SMGs). The Zpectrometer instrument on the Green Bank Telescope (GBT) was used to measure the redshifts and constrain the masses of the cold molecular gas reservoirs for two candidate high-redshift lensed sources. We derive CO(1-0) redshifts of z = 3.042 ± 0.001 and z = 2.625 ± 0.001, and measure molecular gas masses of (1-3) ×1010 M sun, corrected for lens amplification and assuming a conversion factor of α = 0.8 M sun( K km s-1 pc2)-1. We find typical L(IR)/L'(CO) ratios of 120 ± 40 and 140 ± 50 L sun( K km s-1 pc2)-1, which are consistent with those found for local ultraluminous infrared galaxies (ULIRGs) and other high-redshift SMGs. From analysis of published data, we find no evidence for enhanced L(IR)/L'(CO(1-0)) ratios for the SMG population in comparison to local ULIRGs. The GBT results highlight the power of using the CO lines to derive blind redshifts, which is challenging for the SMGs at optical wavelengths given their high obscuration.

    Observations of the Milky Way and nearby galaxies show that dense molecular gas correlates with recent star formation, suggesting that the formation of this gas phase may help regulate star formation. A key test of this idea requires wide-area, high-resolution maps of dense molecular gas in galaxies to explore how local physical conditions drive dense gas formation, but these observations have been limited because of the faintness of dense gas tracers like HCN and HCO+. Here we demonstrate the power of the Robert C. Byrd Green Bank Telescope (GBT)—the largest single-dish millimeter radio telescope—for mapping dense gas in galaxies by presenting the most sensitive maps yet of HCN and HCO+ in the starburst galaxy M82. The HCN and HCO+ in the disk of this galaxy correlates with both recent star formation and more diffuse molecular gas and shows kinematics consistent with a rotating torus. The HCO+ emission extending to the north and south of the disk is coincident with the outflow previously identified in CO and traces the eastern edge of the hot outflowing gas. The central starburst region has a higher ratio of star formation to dense gas than the outer regions, pointing to the starburst as a key driver of this relationship. These results establish that the GBT can efficiently map the dense molecular gas at 90 GHz in nearby galaxies, a capability that will increase further with the 16 element feed array under construction.

    Radio observations of the Ursa Major II dwarf spheroidal galaxy obtained using the Green Bank Telescope are used to place bounds on weakly interacting massive particle (WIMP) dark matter properties. Dark matter annihilation releases energy in the form of charged particles which emit synchrotron radiation in the magnetic field of the dwarf galaxy. We compute the expected synchrotron radiation intensity from WIMP annihilation to various primary channels. The predicted synchrotron radiation is sensitive to the distribution of dark matter in the halo, the diffusion coefficient D0, the magnetic field strength B, the particle mass mχ, the annihilation rate ⟨σav⟩, and the annihilation channel. Limits on ⟨σav⟩, mχ, B, and D0 are obtained for the e+e-, μ+μ-, τ+τ-, and bb¯ channels. Constraints on these parameters are sensitive to uncertainties in the measurement of the dark matter density profile. For the best fit halo parameters derived from stellar kinematics, we exclude 10 GeV WIMPs annihilating directly to e+e- at the thermal rate ⟨σav⟩=2.18×10-26cm3/s at the 2σ level, for B>0.6μG (1.6μG) and D0=0.1(1.0)× the Milky Way diffusion value.

    The Green Canyon (GC) and Ewing Bank (EW) OCS lease areas have 17 discoveries/fields, primarily from bathyal turbidite systems. Salt has played a significant role in the formation of the intraslope basins that the turbidite systems were deposited in, by influencing the flows of turbidities throughout the basin, in the subsequent trap formation, and, in some cases, as a seal. Nearly every field/discovery is associated with a seismic amplitude anomaly. Fields generally have multiple pay zones, with up to 22 in GC 184 (Jolliet). To date, eight of the fields are producing: EB 826, EB 873 (Lobster), GC 6 (Kodiak), GC 18, GC 53/54 (Marquette), GC 65/110 (Bullwinkle), GC 184 (Jolliet), and GC 205 (Vancouver). Other fields expected to be developed are GC 72/116 (Popeye), GC 254 (Allegheny), GC 200/244 (Olivella), GC and GC 166 (Bison). Other discoveries that were produced and then abandoned include GC 19, and GC29. Producing reservoir facies are highly variable across the area. Turbidite reservoir geometries in Pliocene sands (>1.6 Ma) consist of sheets and amalgamated sheet sands. Pleistocene sands are characterized primarily from channel-levee systems and related deposits. These sands tend to more compartmentalized with separate oil/water or gas/water contacts. Most reservoir sands occur within 100 ft overlying a sequence boundary, indicating the eustatic control on the timing of reservoir sand deposition.

    Neutral hydrogen (Hi) provides a very important fuel for star formation, but is difficult to detect at high redshift due to weak emission, limited sensitivity of modern instruments, and terrestrial radio frequency interference (RFI) at low frequencies. We report the first attempt to use gravitational lensing to detect Hi line emission from three gravitationally lensed galaxies behind the cluster Abell 773, two at redshifts of 0.398 and one at z = 0.487, using the Green Bank Telescope. We find that a 3σ upper limit for a galaxy with a rotation velocity of 200 km s-1 is M H i = 6.58 × 109 and 1.5 × 1010 M ⊙ at z = 0.398 and z = 0.487. The estimated Hi masses of the sources at z = 0.398 and z = 0.487 are factors of 3.7 and ˜30 times lower than our detection limits at the respective redshifts. To facilitate these observations we have used sigma-clipping to remove both narrow- and wideband RFI but retain the signal from the source. We are able to reduce the noise of the spectrum by ˜25% using our routine instead of discarding observations with too much RFI. The routine is most effective when ˜10% of the integrations or fewer contain RFI. These techniques can be used to study Hi in highly magnified distant galaxies that are otherwise too faint to detect.

    A significant portion of the process of detecting pulsars from radio sky surveys remains a largely manual task. The visual inspection of data in order to detect and validate potential pulsar candidates is by far the most time consuming portion of the overall process. Coupled with the fact that well over a Petabyte of pulsar survey data has been archived, the task of identifying these valuable phenomena is tedious and time consuming. Using data from a survey performed with the National Radio Astronomy Observatory's (NRAO's) Green Bank Telescope (GBT) in 2007, this thesis explores the application of machine learning techniques to mitigate the manual efforts involved in pulsar candidate detection. The performance of three different classifiers is explored - Naive Bayes, C4.5 (J48) Decision Tree, and Support Vector Machine. Preprocessing and feature extraction methods are described and a framework for applying the classifiers to the survey data is presented. Multiple features were extracted from the survey data and used to train the classifiers. Cross-validation results of the various feature sets and classifiers are documented. Experiments suggest the potential of the proposed framework in rapidly detecting pulsars from large amounts of survey data.

    A non-LTE radiative transfer treatment of cis-methyl formate (HCOOCH{sub 3}) rotational lines is presented for the first time using a set of theoretical collisional rate coefficients. These coefficients have been computed in the temperature range 5-30 K by combining coupled-channel scattering calculations with a high accuracy potential energy surface for HCOOCH{sub 3}-He. The results are compared to observations toward the Sagittarius B2(N) molecular cloud using the publicly available PRIMOS survey from the Green Bank Telescope. A total of 49 low-lying transitions of methyl formate, with upper levels below 25 K, are identified. These lines are found to probe a presumably cold (∼30 K), moderately dense (∼10{sup 4} cm{sup –3}), and extended region surrounding Sgr B2(N). The derived column density of ∼4 × 10{sup 14} cm{sup –2} is only a factor of ∼10 larger than the column density of the trans conformer in the same source. Provided that the two conformers have the same spatial distribution, this result suggests that strongly non-equilibrium processes must be involved in their synthesis. Finally, our calculations show that all detected emission lines with a frequency below 30 GHz are (collisionally pumped) weak masers amplifying the continuum of Sgr B2(N). This result demonstrates the importance and generality of non-LTE effects in the rotational spectra of complex organic molecules at centimeter wavelengths.

    The detection of E-cyanomethanimine (E-HNCHCN) toward Sagittarius B2(N) is made by comparing the publicly available Green Bank Telescope (GBT) PRIMOS survey spectra to laboratory rotational spectra from a reaction product screening experiment. The experiment uses broadband molecular rotational spectroscopy to monitor the reaction products produced in an electric discharge source using a gas mixture of NH{sub 3} and CH{sub 3}CN. Several transition frequency coincidences between the reaction product screening spectra and previously unassigned interstellar rotational transitions in the PRIMOS survey have been assigned to E-cyanomethanimine. A total of eight molecular rotational transitions of this molecule between 9 and 50 GHz are observed with the GBT. E-cyanomethanimine, often called the HCN dimer, is an important molecule in prebiotic chemistry because it is a chemical intermediate in proposed synthetic routes of adenine, one of the two purine nucleobases found in DNA and RNA. New analyses of the rotational spectra of both E-cyanomethanimine and Z-cyanomethanimine that incorporate previous millimeter-wave measurements are also reported.

    The MIT-Green Bank IV (MG IV) 5 GHz survey covers 0.504 sr of sky in the right ascension range 15.5 to 2.5 hours, between +37.00 and +50.98 degrees declination (B1950). The final MG IV catalog contains 3427 sources detected with a signal-to-noise ratio greater than 5. The catalog was produced from two separate north and south surveys with the National Radio Astronomy Observatory (NRAO) 91m transit telescope. The north survey was produced from data collected while scanning the telescope north from +39.0 to +50.98 degrees declination and the south survey from data collected from scans from +48.98 to +37.00 degrees declination. The completeness and reliability of the final source list is checked by examination of north and south source lists in a twice observed comparison region, lying between +39.15 and +48.83 degrees declination and excluding the area between +/-10 degrees Galactic latitude. The comparison region covers 0.270 sr of sky and contains 1094 sources. In this region, the MG IV catalog contains 423 sources brighter than 90 mJy and is shown to be 99.1 +/- 1.2% complete at this flux density level. Spectral indices are computed for sources identified in the NRAO 1400 MHz Survey (published by Condon and Broderick in 1985). A comparison of the spectral index distributions between +/- 10 and outside of +/- 10 degrees Galactic latitude is presented. (1 data file).

    We observed radio continuum emission in 27 local (D < 70 Mpc) star-forming galaxies with the Robert C. Byrd Green Bank Telescope between 26 GHz and 40 GHz using the Caltech Continuum Backend. We obtained detections for 22 of these galaxies at all four sub-bands and four more marginal detections by taking the average flux across the entire bandwidth. This is the first detection (full or marginal) at these frequencies for 22 of these galaxies. We fit spectral energy distributions (SEDs) for all of the four sub-band detections. For 14 of the galaxies, SEDs were best fit by a combination of thermal free-free and nonthermal synchrotron components. Eight galaxies with four sub-band detections had steep spectra that were only fit by a single nonthermal component. Using these fits, we calculated supernova rates, total number of equivalent O stars, and star formation rates within each ∼23'' beam. For unresolved galaxies, these physical properties characterize the galaxies' recent star formation on a global scale. We confirm that the radio-far-infrared correlation holds for the unresolved galaxies' total 33 GHz flux regardless of their thermal fractions, though the scatter on this correlation is larger than that at 1.4 GHz. In addition, we found that for the unresolved galaxies, there is an inverse relationship between the ratio of 33 GHz flux to total far-infrared flux and the steepness of the galaxy's spectral index between 1.4 GHz and 33 GHz. This relationship could be an indicator of the timescale of the observed episode of star formation.

    With a 100-meter aperture, and recent improvements to its surface accuracy and servo system upgrades, the Robert C. Byrd Green Bank Telescope is the most sensitive telescope operating at 90 GHz. A dual-feed heterodyne receiver is developed for observations at the lower frequency end of the 3-4mm atmospheric window (67 to 93 GHz). The science goals are primarily molecular spectroscopic studies of star formation and astrochemistry both internal and external to the Milky Way galaxy. Studies of the structural and physical properties of star-forming, cold-cloud cores will be revolutionized with molecular spectroscopy of the deuterium and other important species within the band. Essential for spectroscopy is the ability to remove slow gain and atmospheric variations. An optical table external to the cooled components rotates into the path of either beam an ambient temperature load, an offset mirror for viewing an internal cold load, or a quarter-wave plate that produces circular polarization for VLBI observations. A composite waveguide window comprised of HDPE, Zitex, and z-cut quartz provides a high-strength, low-loss medium for transmission of the signal to the cooled corrugated feed horn. An orthomode transducer separates the polarization components which are amplified by low noise HEMT amplifiers. Warm W-band MMIC amplifiers are required to compensate a negative gain slope and to reduce noise contributions from the down conversion to the GBT IF frequencies. Initial science results and receiver performance during commissioning observations will be presented along with details of the component design.

    Near-Earth asteroid (436724) 2011 UW158 made a close approach to the Earth on 2015 July 19 at a distance of 0.016 au (6.4 lunar distances). We observed it between July 13-26 using the Arecibo S-band (2380 MHz, 12.5 cm) radar, the Goldstone X-band (8560 MHz, 3.5 cm) radar, and the Green Bank Telescope (GBT). Arecibo delay-Doppler observations achieved range resolutions as fine as 7.5 m. At the GBT, we used a newly installed radar backend to record the radar echoes, which improved signal-to-noise ratios (SNRs) two-fold relative to monostatic reception at the 70-m DSS-14 antenna at Goldstone. The higher SNRs allowed us to obtain images with range resolutions comparable to those at Arecibo that reveal the asteroid’s surface topography with great detail. The visible extents of the asteroid in the radar images suggest an elongated object with dimensions of about 600 x 300 m. The shape of the object is angular with a facet on one side that spans the entire length of the asteroid. Three parallel radar-bright features are visible when the asteroid is oriented broadside and may represent ridges. These features cause unusually large brightness variations in the echo as the asteroid rotates. There are other radar-bright regions that suggest small-scale (tens of meters) topography. Repetition of the leading edge profiles in the images indicates a spin period of ~37 minutes, which is consistent with the period that was previously reported using lightcurves (B. Gary, T. Lister, H. K. Moon, P. Pravec, and B. D. Warner, pers. comm.). This spin period is unusually fast among asteroids its size and suggests that the object has relatively high cohesive strength. 2011 UW158 has a relatively low delta-V for spacecraft missions and is on NASA’s Near-Earth Object Human Accessible Targets Study list.

    Observations of the Milky Way and nearby galaxies show that dense molecular gas correlates with recent star formation, suggesting that the formation of this gas phase may help regulate star formation. A key test of this idea requires wide-area, high-resolution maps of dense molecular gas in galaxies to explore how local physical conditions drive dense gas formation, but these observations have been limited because of the faintness of dense gas tracers like HCN and HCO{sup +}. Here we demonstrate the power of the Robert C. Byrd Green Bank Telescope (GBT)—the largest single-dish millimeter radio telescope—for mapping dense gas in galaxies by presenting the most sensitive maps yet of HCN and HCO{sup +} in the starburst galaxy M82. The HCN and HCO{sup +} in the disk of this galaxy correlates with both recent star formation and more diffuse molecular gas and shows kinematics consistent with a rotating torus. The HCO{sup +} emission extending to the north and south of the disk is coincident with the outflow previously identified in CO and traces the eastern edge of the hot outflowing gas. The central starburst region has a higher ratio of star formation to dense gas than the outer regions, pointing to the starburst as a key driver of this relationship. These results establish that the GBT can efficiently map the dense molecular gas at 90 GHz in nearby galaxies, a capability that will increase further with the 16 element feed array under construction.

    Argus is a new 16-pixel W-band focal plane array for millimeter spectroscopy at the Green Bank Telescope (GBT). Built by a consortium led by Sarah Church at Stanford, this new instrument provides fast astronomical imaging over the 75-116 GHz band and at high spatial resolution. The frequency range covered by Argus is of particular interest for star formation studies and will be excellent at probing cold, dense cores within star-forming regions, along with constraining the dynamics of filamentary structures withing giant molecular cloud complexes. In particular, the 3mm band covers a large number of important spectral lines, including CO (J=1-0) and its isotopologues, as well as HCO+, H13CO+, SiO, N2H+, HCN and HNC. These molecular transitions trace a combination of dense cold gas, shocked emission from jets and outflows as well as the signatures of infall, all of which are imperative constituents in the early stages of star formation. Argus on the GBT will provide the high sensitivity of a filled aperture along with a high angular resolution of 6-10", this resolution is well-matched to the mid- and far-infrared observations from the Spitzer, SOFIA, and Herschel telescopes. We report on the current status of Argus and present recent commissioning and early science highlights from Argus of 12CO, 13CO and HCO+ emission towards the massive star forming region, DR 21. Argus, currently under commissioning, is expected to be in full science mode in the winter semester of 2016.

    Fourteen male elite sprinters performed short-distance sprints and jump tests until 18 days before 100-m dash competitions in track and field to determine if these tests are associated with 100-m sprint times. Testing comprised of squat jumps (SJ), countermovement jumps (CMJ), horizontal jumps (HJ), maximum mean propulsive power relative to body mass in loaded jump squats, and a flying start 50-m sprint. Moderate associations were found between speed tests and competitive 100-m times (r = 0.54, r = 0.61, and r = 0.66 for 10-, 30-, and 50-m, respectively, p ≤ 0.05). In addition, the maximum mean propulsive power relative to body mass was very largely correlated with 100-m sprinting performance (r = 0.75, p < 0.01). The correlations of SJ, CMJ, and HJ with actual 100-m sprinting times amounted to -0.82, -0.85, and -0.81, respectively. Because of their practicality, safeness, and relationship with the actual times obtained by top-level athletes in 100-m dash events, it is highly recommended that SJ, CMJ, and HJ be regularly incorporated into elite sprint-testing routines.

    Visible light communication (VLC) has no doubt become a promising candidate for future wireless communications due to the increasing trends in the usage of light-emitting diodes (LEDs). In addition to indoor high-speed wireless access and positioning applications, VLC usage in outdoor scenarios, such as vehicle networks and intelligent transportation systems, are also attracting significant interest. However, the complex outdoor environment and ambient noise are the key challenges for long-range high-speed VLC outdoor applications. To improve system performance and transmission distance, we propose to use receiver diversity technology in an outdoor VLC system. Maximal ratio combining-based receiver diversity technology is utilized in two receivers to achieve the maximal signal-to-noise ratio. A 400-Mb/s VLC transmission using a phosphor-based white LED and a 1-Gb/s wavelength division multiplexing VLC transmission using a red-green-blue LED are both successfully achieved over a 100-m outdoor distance with the bit error rate below the 7% forward error correction limit of 3.8×10-3. To the best of our knowledge, this is the highest data rate at 100-m outdoor VLC transmission ever achieved. The experimental results clearly prove the benefit and feasibility of receiver diversity technology for long-range high-speed outdoor VLC systems.

    A sequence stratigraphic study of the Plio-Pleistocene sediments in the northeastern Green Canyon and Ewing Bank areas has defined seven deposition sequences (5.5, 4.2, 3.8, 3.0, 1.4, 1.1, 0.8, 0.7, and 0.5 Ma). These sequences were correlated, and detailed seismic and geologic facies were constructed for each sequence. Data base for the study comprises 1,436 line miles of forty-fold, migrated, 2-D seismic data, as well as logs from 25 wells, and biostratigraphic data from 17 wells. The area consists of seven mini-basins separated by salt features with differing geometries, and faults. Paleoecology indicates that the area rested primarily in bathyal settings. The early Pliocene sequences (5.5 to 3.0 Ma) consist of sand-rich, areally widespread turbidite systems comprising basin-floor fans (amalgamated sheet sands), surrounded and overlain by overbank shales. Petroleum discoveries in the area occur primarily in reservoirs in this interval. Structural restorations indicate that most of the mini-basins in the study area began to develop during this period of time associated with loading of shallow salt sheets. The interval between 3.0 - 1.4 Ma represents a major condensed zone, including three stacked condensed sections. Lithologies are dominantly shales with some thin sands. This interval varies from 50 to 200 feet in thickness. During the Pleistocene (1.4 Ma to present), mud-rich turbidite systems were deposited extensively in the area, including channel-levee systems and related settings. Sands tend to be concentrated near sequence boundaries and primarily in channel-fill facies. Extensive overbank settings are interpreted for the mud-rich portion of these sequences, based on both siesmich facies and regional distribution. Extensive slides are present also in this interval. By 0.5 Ma, submarine canyons also began to develop in this area; these canyons are interpereted to have fed sediments in the Mississippi Fan in the deep Gulf of Mexico.

    A diode pumped, Nd:YAG laser producing 100 mJ Q-switched pulses and employing a dual-pump head scheme in an unstable resonator configuration is described. Each head contains a side pumped zig-zag slab and four 6-bar QCW 808 nm diodes arrays which are de-rated 23%. Denoting 'z' as the lasing axis, the pump directions were along the x-axis in one head and the y-axis in the other, producing a circularized thermal lens, more typical in laser rod-based cavities. The dual head design's effective thermal lens is now corrected with a proper HR mirror curvature selection. This laser has demonstrated over 100 mJ output with high optical efficiency (24%), good TEM(sub 00) beam quality, and high pointing stability.

  19. Auditory scene analysis and sensory memory: the role of the auditory N100m.

    We consider the neural dynamics underlying auditory streaming, the perceptual grouping of transient auditory events, by using neural modeling and magnetoencephalographic (MEG) measurements in humans. We demonstrate that spatial variations in the strength of feedback inhibition leads to differential amplitude modulation (AM) tuning resembling that found in animal models. In our model, neurons respond selectively to stimuli presented at different onset-to-onset interstimulus intervals (ISIs), and their summed activity (corresponding to the MEG signal) exhibits both transient and sustained responses (SRs) at fast ISIs. In MEG measurements utilizing 2-s trains of 50-ms stimuli presented at 0-1950 ms ISIs, we observed the transient N100m and SRs predicted by the model, with a prominent SR emerging for discrete stimuli at ISIs below 200 ms. Our results explain why, at fast stimulus rates, the amplitude of the auditory N100m appears to be strongly attenuated even though auditory cortex continues to respond vigorously to the stimuli. The results suggest that the longer and shorter forms of auditory sensory memory may be reflected in the N100m and the SR, respectively. As the emergence of the SR coincides with the stimuli being perceived as auditory streams, our study suggests that auditory sensory memory as indexed by transient and sustained cortical activity might underlie auditory scene analysis.

    We have designed and tested a portable gated-Raman system that is capable of detecting organic and inorganic bulk chemicals over stand-off distances of 100 m and more during day and night time. Utilizing a 532 nm laser pulse (~35 mJ/pulse), Raman spectra of several organic and inorganic compounds have been measured with the portable Raman instrument over a distance of 100 m. Remote Raman spectra, obtained with a very short gate (2 micro second), from a variety of inorganic minerals such as calcite (CaCO3), α-quartz (α-SiO2), barite (BaSO4), and FeSO4.7H2O, and organic compounds such as acetone, methanol, 2-propanol and naphthalene showed all major bands required for unambiguous chemical identification. We also measured the Raman and fluorescence spectra of plant leaves, tomato, and chicken eggshell excited with a 532 nm, 20 Hz pulsed laser and accumulated over 200 laser shots (10-s integration time) at 110 m with good signal-to-noise ratio. The results of these investigations show that remote Raman spectroscopy over a distance of 100 m can be used to identify Raman fingerprints of both inorganic, organic, and some biological compounds on planetary surfaces and could be useful for environmental monitoring.

    The purpose of this study was to determine the influence of different sizes of hand paddles on kinematic parameters during a 100 m freestyle swimming performance in elite swimmers. Nine elite swimmers (19.1 ± 1.9 years) completed three tests of 100 m without paddles, with small paddles (271.27 cm2) and with large paddles (332.67 cm2), respectively. One video camera was used to record the performance during the three trials. The mean swimming velocity, stroke rate and stroke length were measured in the central 10 meters of each 50 m length. The results showed that stroke length tended to increase significantly when wearing hand paddles (p < 0.05) during both the first and second 50 m sections whereas the increase in swimming velocity occurred only in the second 50 m (p < 0.05). Conversely, the stroke rate showed a slight decreasing trend with increasing paddle size. During the 100 m freestyle trial the stroke kinematics were changed significantly as a result of the increase in propelling surface size when hand paddles were worn. PMID:23486988

  3. Data Assimilation of PROBA-V 100 m and 300 m.

    One of the goals of the FP7 SIGMA projects is the extension of remote sensing time series to better monitor agricultural productivity at global scale. Extending these time series can be seen in differnt ways; on the one hand we are looking at the integration of different existing data sets with equal resolution e.g. SPOT-VGT and PROBA-V 1km resolution, or building new time series for Eta and Soil moisture. on the other hand we are also updating methods to extend existing time series with respect to their resolution and revisting frequency. The research presentend here will focus on the latter, focussing on the integration of PROBA-V 100 and 300m. The PROBA-V microsatellite is designed to offer a global coverage of land surfaces at four spectral bands at a spatial resolution of 300 m and 1 km with a daily revisit for latitudes 75°N to 56°S [1]. Due to the specific design, data can also be acquired at 100 m for a reduced swath, providing partial coverage (global coverage only every 5 days). This study proposes a data assimilation method that combines the 100 m data at the reduced swath with PROBA-V 300 m resolution data at the full swath. The resulting product is a synthetic product at 100 m spatial resolution, with a potential revisit time equal to the 300 m products (S10@300). Here, we concentrate on a ten day composite product (K10@100), to mitigate the effect of clouds. The goal of the proposed method is to produce continuous and cloud free time series of PROBA-V data at 100 m spatial resolution. The S10@300 and S10@100 ten day composits serve as input, with respective spatial resolutions of 300 m and 100 m. Whereas the S10@300 is obtained from all sensors onbaord the PROBA-V platform, the S10@100 is the product from the central viewing sensor only. Due to a combination of the reduced swath and potential cloud cover, the S10@100 is typically sparse (gaps). The data assimilation method follows the approach proposed in that is based on a Kalman filter. It is a

    The aim of this study was to develop a normative sample of step frequency and step length during maximal sprinting in amputee sprinters. We analyzed elite-level 100-m races of 255 amputees and 93 able-bodied sprinters, both men and women, from publicly-available Internet broadcasts. For each sprinter's run, the average forward velocity, step frequency, and step length over the 100-m distance were analyzed by using the official record and number of steps in each race. The average forward velocity was greatest in able-bodied sprinters (10.04 ± 0.17 m/s), followed by bilateral transtibial (8.77 ± 0.27 m/s), unilateral transtibial (8.65 ± 0.30 m/s), and transfemoral amputee sprinters (7.65 ± 0.38 m/s) in men. Differences in velocity among 4 groups were associated with step length (able-bodied vs transtibial amputees) or both step frequency and step length (able-bodied vs transfemoral amputees). Although we also found that the velocity was greatest in able-bodied sprinters (9.10 ± 0.14 m/s), followed by unilateral transtibial (7.08 ± 0.26 m/s), bilateral transtibial (7.06 ± 0.48 m/s), and transfemoral amputee sprinters (5.92 ± 0.33 m/s) in women, the differences in the velocity among the groups were associated with both step frequency and step length. Current results suggest that spatiotemporal parameters during a 100-m race of amputee sprinters is varied by amputation levels and sex.

  5. Seasonal and annual variability of the global onshore and offshore wind power resource at 100 m

    2010-12-01

    We present the results of numerical simulations of the global wind power potential over land and offshore with a coupled climate-meteorological-air pollution model, GATOR-GCMOM, that dynamically calculates wind power at the 100-m hub height of a modern 5 MW wind turbine at each time step. The model was run at various horizontal resolutions (4x5, 2x2.5, and 1.5x1.5 degrees of latitude and longitude) and with various initial conditions (summer or winter) for at least four years each. The global delivered wind power potential at 100 m at fast-wind locations (≥7 m/s) over land, excluding both polar regions, is found to be 138-150 TW (TW=1012 Watts) on average. This result further supports previous observation-based estimates of 72 TW at 80 m and model-based estimates of 79-126 TW at 100 m. Seasonal variations are however significant, with values as low as 94-102 TW in June-July-August (JJA) to 218-246 TW in December-January-February (DJF), with minima in September and maxima in January in all simulations. Global wind power over land at fast-wind locations during DJF is 1.6-2.5 times greater than that during JJA on average. Furthermore, the average wind power over land in the Northern Hemisphere (NH) is ˜126 TW, over 5 times greater than the Southern Hemisphere (SH) average (˜24 TW). In December, the NH wind power over land is up to 32 times greater than that in the SH. This suggests that the two hemispheres have different wind resources, driven by the different distributions of land and ocean areas. The offshore delivered wind power potential (excluding polar regions) is 15-23 TW at 100 m on average, consistent with previous estimates of 18-21 TW, varying between 16-17 and 19-31 TW from JJA to DJF. Wind power over land and near shore in fast-wind locations (which are 7-8% of the total land excluding polar regions) represents 7-10% of the theoretical global wind power over land plus ocean at all wind speeds of ˜1700 TW. Available wind power over land and near shore

    On July 16, 1988, Florence Griffith Joyner (FGJ) shattered the women's 100-m dash world record (WR) with a time of 10.49 s, breaking the previous mark by an astonishing 0.27 s. By all accounts FGJ dominated the race that day, securing her place as the premiere female sprinter of that era, and possibly all time. In the aftermath of such an extraordinary performance, track officials immediately assumed that her posted time was wind aided—that is, attained under tailwind conditions beyond the legal limit of 2.0 m/s for world records. However, wind-measuring devices at the track site showed zero wind conditions during her WR performance. Before and during FGJ's race, other wind-measuring devices indicated speeds exceeding 4.0 m/s at the site of the triple jump runway, located on the same field as the running track. Video clips of flags placed near the starting line of FGJ's race also revealed tailwind conditions. Using available data from that era, the study here incorporates modeling techniques to compute velocity and position as functions of time for no wind and tailwind conditions. Modeling under no wind conditions produces a 100-m time of 10.70 s, a performance clearly attainable by FGJ during this stage of her sprinting career. Incorporating tailwinds of 4.0 m/s into the computations reduces this time by approximately 0.20 s, in close agreement with FGJ's record-breaking performance. These results strongly suggest that tailwinds of order 4 m/s were present during FGJ's world record race even though wind-measuring devices at the track site did not register these speeds. In spite of such strong evidence to support a wind-aided race on July 16, 1988, FGJ remains one of the top female sprinters in history and would likely hold the WR even today, given that she attained a non-wind-aided 100-m time of 10.61 s on the day following her WR performance.

    Compact remote spectroscopic instruments that could provide detailed information about mineralogy, organic and biomaterials on a planetary surface over a relatively large area are desirable for NASA s planetary exploration program. Ability to explore a large area on the planetary surfaces as well as in impact craters from a fixed location of a rover or lander will enhance the probability of selecting target rocks of high scientific contents as well as desirable sites in search of organic compounds and biomarkers on Mars and other planetary bodies. We have developed a combined remote inelastic scattering (Raman) and laser-induced fluorescence emission (LIFE) compact instrument capable of providing accurate information about minerals, organic and biogenic materials to a radial distance of 100 m. Here we present the Raman and LIFE (R-LIFE) data set.

    A switched capacitor step-down DC-DC converter (charge pump) is proposed. High efficiency is achieved by combination of fractional conversion ratios (different step-down modes of operation), output voltage sensing and pulse skipping based digital control techniques. Two control techniques were implemented with automatic change between modes and their results are discussed and compared. The power module has 9 switches, implemented with 14 power transistors, and a current limit circuit to mitigate the in-rush current in startup phase. This circuit has been designed in AMS C35B4 (0.35um) CMOS process. The charge pump was designed to provide a maximum load current of 100mA. The peak-to-peak output voltage ripple is less than 30mV with two 3uF flying capacitors and one 20uF output capacitor. Peak and average efficiencies, with maximum load current, are over 80% and 68%, respectively.

    For BERLinPro, a 100 mA CW-driven SRF energy recovery linac demonstrator facility, HZB needs to develop a photo-injector superconducting cavity which delivers a at least 1mm*mr emittance beam at high average current. To address these challenges of producing a high peak brightness beam at high repetition rate, at first HZB tested a fully superconducting injector with a lead cathode*,followed now by the design of a SC cavity allowing operation up to 4 mA using CW-modified TTF-III couplers and inserting a normal conducting high quantum efficiency cathode using the HZDR-style insert scheme. This talk will present the latest results and an overview of the measurements with the lead cathode cavity and will describe the design and optimization process, the first production results of the current design and an outlook to the further development steps towards the full power version.

    S100 family genes encode low molecular weight, acidic-Ca2+ binding proteins implicating in a wide spectrum of biological processes. S100 family contains at least 20 members, most of which are frequently dysregulated in human malignancies including breast cancer. However, the prognostic roles of each individual S100, especially the mRNA level, in breast cancer patients remain elusive. In the current study, we used “The Kaplan-Meier plotter” (KM plotter) database to investigate the prognostic values of S100 mRNA expression in breast cancer. Our results indicated that high mRNA expression of S100A8, S100A9, S100A11 and S100P were found to be significantly correlated to worse outcome, while S100A1 and S100A6 were associated with better prognosis in all breast cancer patients. We further assessed the prognostic value of S100 in different intrinsic subtypes and clinicopathological features of breast cancer. The associated results will elucidate the role of S100 in breast cancer and may further lead the research to explore the S100-targeting reagents for treating breast cancer patients. PMID:28051137

    Due to gravitation the main reflector of the Effelsberg 100-m telescope of the Max Planck Institute for Radio Astronomy is deformed whenever it is tilted from zenith to arbitrary elevation angles. However, the resulting shape always is a paraboloid again, though with different parameters, a phenomenon which is called homologous deformation. In summer 2008, we have carried out measurements with a total station to determine the magnitude of these deformations in order to evaluate existing assumptions provided by the manufacturer from the telescope's design phase. The measurements are based on a newly developed approach with a Leica TCRP 1201 total station mounted head down near the subreflector. Mini-retro-reflectors are placed at various locations on the paraboloid itself and on the subreflector support structure. The results indicate that the measurement setup is suitable for the purpose and provides the information needed for a determination of elevation dependent delay corrections. The focal length changes only by about 8 mm when the telescope is tilted from 90. to 7.5. elevation angle.

    Recent studies have found evidence that global climate change significantly alters the strength of large-scale wind patterns. Any enduring trends over large regions are potentially of value to understand due to their implications for the wind energy industry. In this study we identify and evaluate global wind speed trends at the wind turbine hub height (~100m) through the use of CMIP5 models, standard reanalyses (ERA-Interim, NCEP2) and a uniquely high-resolution analysis dataset (Vestas Mesoscale Library). By analyzing how wind speeds change across the globe throughout the period 1900-2100 (with emphasis on the satellite era, 1979-2014), we assess the significance of multi-decadal wind speed trends in the context of natural spatial and temporal variability. Our results show substantial differences in regional trends between different datasets though several regions including the Southern Hemisphere mid-latitudes and the Caribbean show consistently substantial changing wind speeds during the satellite era. Wind speed trends tend to diminish over large time scales and follow spatial patterns that link multi-decadal trends to the evolving behaviors of internal variability modes, especially those of ENSO and the Southern Annular Mode (SAM).

    The aim of this study was to investigate differences of the spatiotemporal parameters in a 100-m sprint among elite, sub-elite, and non-elite sprinters with a unilateral transtibial amputation. Using publicly available Internet broadcasts, we analyzed 125, 19, and 33 records from 30 elite, 12 sub-elite, and 22 non-elite sprinters, respectively. For each sprinter’s run, the average velocity, step frequency, and step length were calculated using the number of steps in conjunction with the official race time. Average velocity was greatest in elite sprinters (8.71±0.32 m/s), followed by the sub-elite (8.09±0.06 m/s) and non-elite groups (7.72±0.27 m/s). Although there was a significant difference in average step frequency between the three groups, the effect size was small and the relative difference among the three groups was 3.1%. Statistical analysis also revealed that the average step length was longest in elite sprinters, followed by the sub-elite and non-elite groups. These results suggest that the differences in sprint performance between the three groups is mainly due to the average step length rather than step frequency. PMID:27701443

    We have completed a 350 MHz Drift-scan Survey using the Robert C. Byrd Green Bank Telescope with the goal of finding new radio pulsars, especially millisecond pulsars that can be timed to high precision. This survey covered {approx}10,300 deg{sup 2} and all of the data have now been fully processed. We have discovered a total of 31 new pulsars, 7 of which are recycled pulsars. A companion paper by Boyles et al. describes the survey strategy, sky coverage, and instrumental setup, and presents timing solutions for the first 13 pulsars. Here we describe the data analysis pipeline, survey sensitivity, and follow-up observations of new pulsars, and present timing solutions for 10 other pulsars. We highlight several sources-two interesting nulling pulsars, an isolated millisecond pulsar with a measurement of proper motion, and a partially recycled pulsar, PSR J0348+0432, which has a white dwarf companion in a relativistic orbit. PSR J0348+0432 will enable unprecedented tests of theories of gravity.

    Ammonia (3, 3) and (6, 6) transitions have been observed using the Green Bank Telescope toward the Sgr A region. The gas is mainly concentrated in 50 km s{sup -1} and 20 km s{sup -1} clouds located in a plane inclined to the galactic plane. These 'main' clouds appear to be virialized and influenced by the expansion of the supernova remnant Sgr A East. The observed emission shows very complicated features in the morphology and velocity structure. Gaussian multi-component fittings of the observed spectra revealed that various 'streaming' gas components exist all over the observed region. These components include those previously known as 'streamers' and 'ridges', but most of these components appear not to be directly connected to the major gas condensations (the 50 km s{sup -1} and 20 km s{sup -1} clouds). They are apparently located out of the galactic plane, and they may have a different origin than the major gas condensations. Some of the streaming components are expected to be sources that feed the circumnuclear disk of our Galactic center directly and episodically. They may also evolve differently than major gas condensations under the influence of the activities of the Galactic center.

    The 100-m radio telescope of the Max-Planck-Institut für Radioastronomie (MPIfR) is a unique European astronomical facility that combines superb sensitivity and wide frequency coverage (300 MHz - 95 GHz) with distinct versatility, making the telescope not only a cutting edge instrument for front-line research but also a testbed for emerging and future technology.Even more than 40 years old, the telescope has been continuously modernized and is heavily involved in various kinds of astronomical research as stand-alone instrument as well as in several VLBI networks. Currently, a large upgrade of the receiver suite at the telescope is ongoing. Several new, state-of-the-are broad-band receivers have been installed recently or are under constructions. Along with the new receivers, modern digital backends are being designed. We report on the current status of these upgrades by presenting some „highlights" and giving an outlook on the activities planned for the future.The technology developed and tested during these upgrades also finds application in the MeerKAT observatory in South Africa. MeerKAT is a fully funded radio observatory under construction in the Northern Cape of South Africa. When complete, MeerKAT’s 64 13.5-m dishes will form the - by far - most sensitive telescope in the Southern hemisphere, being equivalent to a 110 m dish. Due to the dish design with an offset Gregorian feed it will be 60%more sensitive than large center feed single dishes of comparable size.MPIfR is designing and constructing a 1.75- 3.44 GHz Receiver system for MeerKAT. The receiver will allow observations at a frequency range at currently unavailable sensitivity and spatial resolution in the Southern hemisphere. Combined with its powerful MPIfR Pulsar search backend it is expected to detect more than 1600 normal and 270 millisecond pulsars. In addition MeerKat will open up science that stays for its own but also prepares future observations with SKA and complements future SKA

    We present results from eight months of Green Bank Telescope 8.7 GHz observations and nearly 18 months of Swift X-ray telescope observations of the radio magnetar SGR J1745–2900. We tracked the radio and X-ray flux density, polarization properties, profile evolution, rotation, and single-pulse behavior. We identified two main periods of activity. The first is characterized by approximately 5.5 months of relatively stable evolution in radio flux density, rotation, and profile shape, while in the second these properties varied substantially. Specifically, a third profile component emerged and the radio flux also became more variable. The single pulse properties also changed, most notably with a larger fraction of pulses with pulse widths ∼5–20 ms in the erratic state. Bright single pulses are well described by a log-normal energy distribution at low energies, but with an excess at high energies. The 2–10 keV flux decayed steadily since the initial X-ray outburst, while the radio flux remained stable to within ∼20% during the stable state. A joint pulsar timing analysis of the radio and X-ray data shows a level of timing noise unprecedented in a radio magnetar, though during the time covered by the radio data alone the timing noise was at a level similar to that observed in other radio magnetars. While SGR J1745–2900 is similar to other radio magnetars in many regards, it differs by having experienced a period of relative stability in the radio that now appears to have ended, while the X-ray properties evolved independently.

    In a previous presentation, I reported on how the freak collapse of the NRAO 300-ft transit radio telescope led to the inclusion of $75 million for a new radio telescope in the 1989 Congressional Emergency Supplemental Appropriations Act. But, this was only the beginning. NRAO was faced with challenging specifications and an unworkable schedule, but there was no design and no project team. Only one bid was even close to the Congressional appropriation. In an attempt to meet the unrealistic antenna delivery date, the contractor started construction of the foundation and fabrication of antenna members before the design was finished, leading to retrofits, redesign, and multiple delays. The antenna contractor was twice sold to other companies leading to further delays and cost escalation. In order to recoup their mounting losses, the new owners sued NRAO for $29 million for claimed design changes, and NRAO countersued demanding to be reimbursed for added project management costs and lost scientific data resulting from the seven-year delay in the completion of the telescope. Legal fees and a small net award in favor of the contractor left NRAO and the NSF with a nine million dollar bill which NSF handled by an innovative accounting adjustment.

  1. 100 M.a. remagnetization as a dating tool for deformation and cleavage in the Central High Atlas (Morocco)

    The High Atlas is an intracontinental chain developed as a result of the inversion of Mesozoic basins during the Cenozoic. Its structure is characterized by ENE-WSW tight anticlines limited by wide synclines. In the central sector of the chain, a pervasive tectonic foliation affects Jurassic limestones and marls. There is a controversy about the age of this tectonic foliation and its relationship with either a Late Jurassic or Cenozoic compressional events. The Jurassic carbonates of the Central High Atlas (CHA) show a widespread syntectonic remagnetization carried by magnetite and dated at 100 M.a. by comparing the paleomagnetic direction obtained by small circle intersection (SCI) method with the apparent polar wander path in NW Africa coordinates. Once the 100 M.a. paleomagnetic direction is known, the obtained paleomagnetic direction remagnetization in each site can be used to restore the bedding at the time of the acquisition. In each site, the in situ mean direction of remagnetization defines a small circle (SC) in a complete rotation about the strike of the bedding. This SC gives all possible original directions of the magnetization and if all deformation events are coaxial and without vertical rotation (as it is the case in the study area) all the SC contains the 100 M.a. expected direction. Then, the angle between the 100 M.a. and the in situ paleomagnetic direction along the small circle, equals the angle of rotation of each bed to ultimately find their dips (paleodip) at 100 M.a. Since the consistency between folding and cleavage can be examined from their geometrical relationship, and bedding can be restored to its 100 M.a. geometry (paleodips obtained from paleomagnetic analysis), two end-members exist for the different examined folds: (i) cleavage is consistent with present-day bedding orientation and attitude of bedding was acquired after remagnetization (Cenozoic cleavage), (ii) cleavage is consistent with bedding, but dip of bedding was acquired

    During April 1999, the U.S. Geological Survey (USGS) conducted a 13-day cruise in the Garden Banks and Green Canyon regions of the Gulf of Mexico. The R/V Gyre, owned by Texas A&M University, was chartered for the cruise. The general objectives were (1) to acquire very high resolution seismic-reflection data and side-scan sonar images of the upper and middle continental slope (200-1200-m water depths), (2) to study the acoustic character and features of the sea floor for evidence of sea-floor hazards, and (3) to look for evidence of subsurface gas hydrates and their effects. The Gulf of Mexico is well known for hydrocarbon resources, with emphasis now on frontier deep-water areas. For water depths greater than about 250 m, the pressure-termperature conditions are correct for the development of shallow-subsurface gas hydrate formation (Anderson et al., 1992). Gas hydrates are ice-like mixtures of gas and water (Kvenvolden, 1993). They are known to be present from extensive previous sampling in sea-floor cores and from mound-like features observed on the sea floor in many parts of the northern Gulf, including the Green Canyon and Garden Banks areas (e.g., Roberts, 1995). Seismic-reflection data are extensive in the Gulf of Mexico, but few very-high-resolution data like those needed for gas-hydrate studies exist in the public domain. The occurrence and mechanisms of gas hydrate formation and dissociation are important to understand, because of their perceived economic potential for methane gas, their potential controls on local and regional sea-floor stability, and their possible effects on earth climates due to massive release of methane greenhouse gas into the atmosphere. Three high-resolution seismic-reflection systems and one side-scan sonar system were used on the cruise to map the surface reflectance and features of the sea floor and the acoustic geometries and character of the shallow sub-surface. The cruise was designed to acquire regional and detailed local

    We present images of C110α and H110α radio recombination line (RRL) emission at 4.8 GHz and images of H166α, C166α, and X166α RRL emission at 1.4 GHz, observed toward the star-forming region NGC 2024. The 1.4 GHz image with angular resolution ∼70'' is obtained using Very Large Array (VLA) data. The 4.8 GHz image with angular resolution ∼17'' is obtained by combining VLA and Green Bank Telescope data in order to add the short and zero spacing data in the uv plane. These images reveal that the spatial distributions of C110α line emission is confined to the southern rim of the H II region close to the ionization front whereas the C166α line emission is extended in the north-south direction across the H II region. The LSR velocity of the C110α line is 10.3 km s{sup –1} similar to that of lines observed from molecular material located at the far side of the H II region. This similarity suggests that the photodissociation region (PDR) responsible for C110α line emission is at the far side of the H II region. The LSR velocity of C166α is 8.8 km s{sup –1}. This velocity is comparable with the velocity of molecular absorption lines observed from the foreground gas, suggesting that the PDR is at the near side of the H II region. Non-LTE models for carbon line-forming regions are presented. Typical properties of the foreground PDR are T {sub PDR} ∼ 100 K, n{sub e}{sup PDR}∼5 cm{sup –3}, n {sub H} ∼ 1.7 × 10{sup 4} cm{sup –3}, and path length l ∼ 0.06 pc, and those of the far side PDR are T {sub PDR} ∼ 200 K, n{sub e}{sup PDR}∼ 50 cm{sup –3}, n {sub H} ∼ 1.7 × 10{sup 5} cm{sup –3}, and l ∼ 0.03 pc. Our modeling indicates that the far side PDR is located within the H II region. We estimate the magnetic field strength in the foreground PDR to be 60 μG and that in the far side PDR to be 220 μG. Our field estimates compare well with the values obtained from OH Zeeman observations toward NGC 2024. The H166α spectrum shows narrow (1

    The use of swimming aids during training contributes to greater swimming efficiency by the improvement of the swimming specific power of the athlete. The purpose of this study was to compare the swimming stroke technical characteristics and the physiological responses of swimming 100-m backstroke, with and without the use of paddles at maximum and sub-maximum intensities at the same swimming speed. Eight swimmers competing at the national level participated in this study. The measurements took place at 4 different sessions. At every session, each participant swam individually one 100-m backstroke swimming trial with or without paddles at the same speed and two levels of intensity (100% and 85% of maximum speed). The results revealed lower stroke length, greater stroke number and gliding length without the use of swimming paddles at both intensities. Blood lactate concentration (10.03±2.96 vs. 5.85±2.23 mmol/l) and Rating of Perceived Exertion (17.43±2.07 vs. 12±2.82) were greater without the use of swimming paddles only at 100% of maximum speed. Thus, swimming backstroke with paddles compared to unaided swimming, at a similar speed, showed a greater efficiency at maximal but not at sub-maximal intensity. PMID:25031685

    This study aimed to compare the force (F)-velocity (v)-power (P)-time (t) relationships of female and male world-class sprinters. A total of 100 distance-time curves (50 women and 50 men) were computed from international 100-m finals, to determine the acceleration and deceleration phases of each race: (a) mechanical variables describing the velocity, force, and power output; and (b) F-P-v relationships and associated maximal power output, theoretical force and velocity produced by each athlete (Pmax , F0 , and V0 ). The results showed that the maximal sprint velocity (Vmax ) and mean power output (W/kg) developed over the entire 100 m strongly influenced 100-m performance (r > -0.80; P ≤ 0.001). With the exception of mean force (N/kg) developed during the acceleration phase or during the entire 100 m, all of the mechanicals variables observed over the race were greater in men. Shorter acceleration and longer deceleration in women may explain both their lower Vmax and their greater decrease in velocity, and in turn their lower performance level, which can be explained by their higher V0 and its correlation with performance. This highlights the importance of the capability to keep applying horizontal force to the ground at high velocities.

    The different response characteristics of the different auditory cortical responses under conventional central masking conditions were examined by comparing the effects of contralateral white noise on the cortical component of 40-Hz auditory steady state fields (ASSFs) and the N100 m component in auditory evoked fields (AEFs) for tone bursts using a helmet-shaped magnetoencephalography system in 8 healthy volunteers (7 males, mean age 32.6 years). The ASSFs were elicited by monaural 1000 Hz amplitude modulation tones at 80 dB SPL, with the amplitude modulated at 39 Hz. The AEFs were elicited by monaural 1000 Hz tone bursts of 60 ms duration (rise and fall times of 10 ms, plateau time of 40 ms) at 80 dB SPL. The results indicated that continuous white noise at 70 dB SPL presented to the contralateral ear did not suppress the N100 m response in either hemisphere, but significantly reduced the amplitude of the 40-Hz ASSF in both hemispheres with asymmetry in that suppression of the 40-Hz ASSF was greater in the right hemisphere. Different effects of contralateral white noise on these two responses may reflect different functional auditory processes in the cortices.

    Air quality inside buildings, whether naturally or mechanically ventilated, is strongly dependent on that of ambient external air in the surrounding atmosphere. This paper describes results obtained in the assessment of urban air quality influence in the neighbouring of a tall, multistorey building with mechanical ventilation on its indoor air quality. Within the study, which lasted for more than 30 d of continuous monitoring, the concentrations of carbon monoxide (CO), of total and grossly speciated classes of airborne organic vapours and of PM 10 airborne particulate were measured both outdoors, at ground and at various heights between street level and the top of the tower building (approximately 100 m) and inside the building. The daily variation of airborne pollutants in the urban atmosphere in the neighbouring of the tower building was traced as the contribution of both time-dependent pollutant production from urban outdoor sources (mainly vehicular traffic) and of the variation of meteoclimatic conditions influencing pollutant diffusion from street level upwards. In particular, a steady concentration decrease with increasing height of the concentration of automotive-related pollutants, such as of PM 10 airborne particulate, of a mixture of volatile aromatic compounds (TAAC) and of CO could be measured in the immediate neghbouring of the tower building (values of 40 μg m -3 of PM 10 airborne particulate decreasing to 32 μg m -3 at 80 m; of 5 mg of benzene equivalents m -3 at ground level with a 30% decrease at 100 m height; of 3 mg m -3 of CO decreasing to 2.2 mg m -3 at 100 m). The acquired information was employed to advice the building management on the improvement of indoor air quality attainable by moving the air feed grid of the HVAC system to a higher level from ground. An example is reported, which shows the improvement of the indoor air quality in a three-storey peripheral building of the same complex subject to scheduled refurbishing, obtained by

    Studying the variability of polarized AGN jet emission in the radio band is crucial for understanding the dynamics of moving shocks as well as the structure of the underlying magnetic field. The 100-m Effelsberg Telescope is a high-quality instrument for studying the long-term variability of both total and polarized intensity as well as the electric-vector position angle. Since 2007, the F-GAMMA program has been monitoring the linear polarized emission of roughly 60 blazars at 11 frequencies between 2.7 and 43 GHz. Here, we describe the calibration of the polarimetric data at 5 and 10 GHz and the resulting F-GAMMA full-Stokes light curves for the exemplary case of the radio galaxy 3C 111.

    The VO2 response to extreme-intensity exercise and its relationship with sports performance are largely unexplored. This study investigated the pulmonary VO2 kinetics during all-out 100-m front crawl whole stroke swimming (S), arm stroke (A) and leg kick (L). 26 male and 10 female competitive swimmers performed an all-out S trial followed by A and L of equal duration in random order. Breath-by-breath VO2 was measured using a snorkel attached to a portable gas analyzer. Mean (±SD) primary component parameters and peak blood lactate (Lapeak) during S, A, and L were, respectively: time delay (s), 14.2 ± 4.7, 14.3 ± 4.5, 15.6 ± 5.1; amplitude (ml·kg(-1)·min(-1)), 46.8 ± 6.1, 37.3 ± 6.9, 41.0 ± 4.7; time constant (τ, s): 9.2 ± 3.2, 12.4 ± 4.7, 10.1 ± 3.2; Lapeak (mmol·l(-1)), 6.8 ± 3.1, 6.3 ± 2.5, 7.9 ± 2.8. During A and L respectively, 80% and 87% of amplitude in S was reached, whereas A+L were 68% greater than in S. 100-m performance was associated to shorter cardiodynamic phase and greater VO2 amplitude and Lapeak (accounting up to 61% of performance variance), but not to τ. We conclude that (i) VO2 gain was proportional to exercise intensity and muscle mass involved, (ii) kicking is metabolically less efficient, and (iii) the main limiting factor of peak VO2 appears to be O2 delivery and not muscle extraction.

We sampled Leptoseris spp. in Hawaii via manned submersibles across a depth range of 67 - 100 m. Both the host and Symbiodinium communities were genotyped, using a non-coding region of the mitochondrial ND5 intron (NAD5) and the nuclear ribosomal internal transcribed spacer region 2 (ITS2), respectively. Results Coral colonies harbored endosymbiotic communities dominated by previously identified shallow water Symbiodinium ITS2 types (C1_ AF333515, C1c_ AY239364, C27_ AY239379, and C1b_ AY239363) and exhibited genetic variability at mitochondrial NAD5. Conclusion This is one of the first studies to examine genetic diversity in corals and their endosymbiotic dinoflagellates sampled at the limits of the depth and light gradients for hermatypic corals. The results reveal that these corals associate with generalist endosymbiont types commonly found in shallow water corals and implies that the composition of the Symbiodinium community (based on ITS2) alone is not responsible for the dominance and broad depth distribution of Leptoseris spp. The level of genetic diversity detected in the coral NAD5 suggests that there is undescribed taxonomic diversity in the genus Leptoseris from Hawaii.

    To study the likely effects of global warming on open-field vegetation, hexagonal arrays of infrared heaters are currently being used for low-stature (<1 m) plants in small ({le}3 m) plots. To address larger ecosystem scales, herein we show that excellent uniformity of the warming can be achieved using nested hexagonal and rectangular arrays. Energy costs depend on the overall efficiency (useable infrared energy on the plot per electrical energy in), which varies with the radiometric efficiency (infrared radiation out per electrical energy in) of the individual heaters and with the geometric efficiency (fraction of thermal radiation that falls on useable plot area) associated with the arrangement of the heaters in an array. Overall efficiency would be about 26% at 4 ms{sup -1} wind speed for a single hexagonal array over a 3-m-diameter plot and 67% for a 199-hexagon honeycomb array over a 100-m-diameter plot, thereby resulting in an economy of scale.

    Using continuous two wavelength near-infrared technology to detect the variation in the consistency of oxygen hemoglobin in the muscle and the sports heart rate wireless real time collection technology, we devised the real time muscle tissue oxygenation and instantaneous heart rate experiment scheme and implemented it for the process of the 100 m run with two parameters given simultaneously. The experiment shows that the concentration of the oxygen hemoglobin in the muscle tissue continues decreasing after the end of the 100 m run, and the time interval between the moment when the concentration of the oxygen hemoglobin attains the minimum value and the moment when the athletes finish the 100 m run is (6.65 +/- 1.10) sec; while the heart rate continues increasing after the end of the 100 m run, and the time interval between the moment when the heart rate attains the maximum value and the moment when the athletes finish the 100 m run is (8.00 +/- 1.57) sec. The results show that the two wavelength near-infrared tissue oxygenation detection technology and the sports heart rate real time collection equipment can accurately measure the sports tissue oxygenation and the heart rate in the extreme intensity sport, and reveal the process of muscle oxygen transportation and consumption and its dynamic character with the heart rate in the extreme intensity sport.

    The purpose of this study was to investigate the acute effects of an all-out 100-m swimming sprint on changes in serum enzyme and calcium ion concentrations in young (12 to 14 years) male and female swimmers. Changes in serum enzyme concentrations of creatine kinase (CK), lactate dehydrogenase (LDH), glutamic pyruvate transaminase (GPT), glutamic oxaloacetate transaminase (GOT), serum glucose (GL), and calcium ion ((Ca2+) concentrations were measured in 23 elite swimmers (13 boys and 10 girls) before and after a 100-m freestyle all-out sprint. Analysis showed (1) there were significant sex differences in serum CK concentration at baseline (Pretest); (2) significant sex differences in serum CK and LDH concentrations after the 100-m spring; (3) no significant differences in Ca2+ concentration after the 100-m spring; and (4) significant increase in Serum GOT and blood glucose concentrations after the 100-m sprint, suggesting that these might both be useful indicators of anaerobic exercise stress in young swimmers.

  16. The acute effects of static stretching on the sprint performance of collegiate men in the 60- and 100-m dash after a dynamic warm-up.

    Previous research has shown that static stretching has an inhibitory effect on sprinting performances up to 50 m. The purpose of this study was to see what would happen to these effects at longer distances such as those seen in competition. This study used a within-subjects design to investigate the effects of passive static stretching vs. no stretching on the 60- and 100-m sprint performance of college track athletes after a dynamic warm-up. Eighteen male subjects completed both the static stretching and the no stretching conditions in counterbalanced order across 2 days of testing. On each day, all subjects first completed a generalized dynamic warm-up routine that included a self-paced 800-m run, followed by a series of dynamic movements, sprint, and hurdle drills. At the end of this generalized warm-up, athletes were assigned to either a static stretching or a no-stretching condition. They then immediately performed 2 100-m trials with timing gates set up at 20, 40, 60, and 100 m. Results revealed a significant slowing in performance with static stretching (p < 0.039) in the second 20 (20-40) m of the sprint trials. After the first 40 m, static stretching exhibited no additional inhibition of performance in a 100-m sprint. However, although there was no additional time loss, athletes never gained back the time that was originally lost in the first portion of the trials. Therefore, in strict terms of performance, it seems harmful to include static stretching in the warm-up protocol of collegiate male sprinters in distances up to 100 m.

  17. Bank Terminals

    NASA Technical Reports Server (NTRS)

    1978-01-01

    In the photo, employees of the UAB Bank, Knoxville, Tennessee, are using Teller Transaction Terminals manufactured by SCI Systems, Inc., Huntsville, Alabama, an electronics firm which has worked on a number of space projects under contract with NASA. The terminals are part of an advanced, computerized financial transaction system that offers high efficiency in bank operations. The key to the system's efficiency is a "multiplexing" technique developed for NASA's Space Shuttle. Multiplexing is simultaneous transmission of large amounts of data over a single transmission link at very high rates of speed. In the banking application, a small multiplex "data bus" interconnects all the terminals and a central computer which stores information on clients' accounts. The data bus replaces the maze-of wiring that would be needed to connect each terminal separately and it affords greater speed in recording transactions. The SCI system offers banks real-time data management through constant updating of the central computer. For example, a check is immediately cancelled at the teller's terminal and the computer is simultaneously advised of the transaction; under other methods, the check would be cancelled and the transaction recorded at the close of business. Teller checkout at the end of the day, conventionally a time-consuming matter of processing paper, can be accomplished in minutes by calling up a summary of the day's transactions. SCI manufactures other types of terminals for use in the system, such as an administrative terminal that provides an immediate printout of a client's account, and another for printing and recording savings account deposits and withdrawals. SCI systems have been installed in several banks in Tennessee, Arizona, and Oregon and additional installations are scheduled this year.

    A 100 m{sup 2} muon detector (MD) was successfully constructed under the existing Tibet air shower (AS) array in the late fall of 2007. The sensitivity of the Tibet AS array to cosmic gamma rays can be improved by selecting muon-poor events with the MD. Our MC simulation of the MD response reasonably agrees with the experimental data in terms of the charge distribution for one-muon events and the background rejection power. Using the data collected by the Tibet AS array and the 100 m{sup 2} MD taken from 2008 March to 2010 February, we search for continuous gamma-ray emission from the Crab Nebula above ∼100 TeV. No significant excess is found, and the most stringent upper limit is obtained above 140 TeV.

    At its meeting in October 2006 in Querétaro, Mexico, the Interamerican Metrology System (SIM) Technical Committee for Fluid Flow (TCFF) approved a Regional Key Comparison for Volume of Liquids at 20 L and 100 mL, to be piloted by the national metrology institute of Mexico (CENAM). The objective of this comparison was to demonstrate the degree of equivalence of the volume measurement standards held at national measurement institutes (NMIs) and to provide supporting evidence for the Calibration and Measurement Capabilities (CMCs) claimed by the participating laboratories in the Americas. During the comparison, one of the pycnometers suffered irreversible damage, and degrees of equivalence for volume at 100 mL were calculated using the results obtained with one single pycnometer (TS 03.04.04). Conclusions are as follows: The transfer standards for SIM.M.FF-K4 exhibited global good performance all the way along, both in terms of stability and repeatability. Degrees of equivalence have been produced for volumes at 20 L and at 100 mL. The best estimation of the measurands, as reported by the participants, shows a general agreement better than +/-0.0070% for volume of liquids at 100 mL and 20 L. It is advisable to review the uncertainty analysis of some participants. New CMC entries for some NMIs should take into account the information presented in this Report. Main text.

    A key comparison was performed in order to compare national measurement systems to determine volume of liquids, particularly at fixed volumes of 20 L and 100 mL. The participants were CENAM (Mexico), NIST (United States of America), NRC/MC (Canada), SP (Sweden), PTB (Germany), INRIM (former IMGC, Italy), NMIA (Australia) and INMETRO (Brazil). CENAM acted as pilot laboratory. The measurements were carried out from December 2003 to March 2005. The chosen values of volume (20 L and 100 mL) are both representatives of the Calibration and Measurement Capabilities (CMCs) declared by most of the participating national metrology institutes. The transfer standards (TSs) were three stainless steel pipettes for volume at 20 L and six commercially available glass pycnometers for volume at 100 mL. Prior to the beginning of the key comparison, the 20 L TSs were tested by CENAM, SP and NMIA The results of the test phase showed excellent values for both repeatability and reproducibility. During the CCM.FF-K4, the results of most of the laboratories showed good agreement with the reference values. The best estimation of the measurands, as reported by the participants showed a general agreement better than ±0.0025% for volume of liquids at 100 mL and 20 L. Main text.

    Discrete Multitone Transmission (DMT) transmission over standard multimode fiber (MMF) using high-speed single (SM) and multimode (MM) Vertical-Cavity Surface-Emitting Lasers (VCSELs) is studied. Transmission speed in the range of 72Gbps to 82Gbps over 300m -100m distances of OM4 fiber is realized, respectively, at Bit-Error-Ratio (BER) <5e-3 and the received optical power of only -5dBm. Such BER condition requires only 7% overhead for the conversion to error-free operation using single Bose-Chaudhuri-Hocquenghem forward error correction (BCH-FEC) coding and decoding. SM VCSEL is demonstrated to provide a much higher data transmission capacity over MMF. For 100m MMF transmission SM VCSEL allows 82Gbps as compared to MM VCSEL resulting in only 34Gbps at the same power (-5dBm). Furthermore, MM VCSEL link at 0dBm is still restricted at 100m distance by 63Gbps while SM VCSEL can exceed 100Gbps at such power levels. We believe that with further improvement in SM VCSELs and fiber coupling >100Gbps data transmission over >300m MMF distances at the BER levels matching the industry standards will become possible.

    A SIM/ANDIMET comparison for liquid volume using two 100 mL pycnometers and two 100 μL piston pipettes was performed between January 2012 and October 2013. The National Metrology Institute (NMI) of Bolivia was the coordinating laboratory and the Mexican NMI provided technical assistance. The participating labs were IBMETRO (Bolivia), INM (Colombia), INEN (Ecuador), INDECOPI (Peru), LACOMET (Costa Rica), LATU (Uruguay), INTN (Paraguay), and CENAM (Mexico). Based on measurements made by CENAM at the beginning and end of the comparison, the transfer standards were stable during the comparison within 0.0001 mL for the 100 mL pycnometers and 0.03 μL for the 100 μL pipettes. For 100 mL, six of the eight participants agreed within ± 0.003 % and had standardized degrees of equivalence (EN) less than 1. Two participants (INEN and INM) had EN values greater than 1. For the 100 μL pipettes, the results were corrected for the influence of altitude and seven of the eight participants agreed within ± 0.3 %. Results from INEN and some from INM and IBMETRO had EN values greater than 1 for the 100 μL pipettes. Uncertainties recommended by Guideline DKD-R 8-1 for micropipettes were included.

    We describe a close-packed, two-dimensional imaging detector system for operation at 90GHz (3.3 mm) for the 100m Green Bank Telescope (GBT). This system will provide high sensitivity (less than 1mJy in 1s) rapid imaging (15'x15' to 150 micron Jy in 1 hr) at the world's largest steerable aperture. The heart of this camera is an 8x8 close-packed, Nyquist-sampled array of superconducting transition edge sensor (TES) bolometers. We have designed and are producing a functional superconducting bolometer array system using a monolithic planar architecture and high-speed multiplexed readout electronics. With an NEP of approximately 2 x 10(exp -17) W/square root of Hz, the TES bolometers will provide fast, linear, sensitive response for high performance imaging. The detectors are read out by an 8x8 time domain SQUID multiplexer. A digital/analog electronics system has been designed to enable read out by SQUID multiplexers. First light for this instrument on the GBT is expected within a year.

    This study aimed to clarify the contribution of differences in step length and step rate to sprinting velocity in an athletic race compared with speed training. Nineteen well-trained male and female sprinters volunteered to participate in this study. Sprinting motions were recorded for each sprinter during both 100-m races and speed training (60-, 80-, and 100-m dash from a block start) for 14 days before the race. Repeated-measures analysis of covariance was used to compare the step characteristics and sprinting velocity between race and speed training, adjusted for covariates including race-training differences in the coefficients of restitution of the all-weather track, wind speed, air temperature, and sex. The average sprinting velocity to the 50-m mark was significantly greater in the race than in speed training (8.26 ± 0.22 m·s vs. 8.00 ± 0.70 m·s, p < 0.01). Although no significant difference was seen in the average step length to the 50-m mark between the race and speed training (1.81 ± 0.09 m vs. 1.80 ± 0.09 m, p = 0.065), the average step rate was significantly greater in the race than in speed training (4.56 ± 0.17 Hz vs. 4.46 ± 0.13 Hz, p < 0.01). These findings suggest that sprinters achieve higher sprinting velocity and can run with higher exercise intensity and more rapid motion during a race than during speed training, even if speed training was performed at perceived high intensity.

    The cause and progression of Alzheimer's disease (AD) are poorly understood. Possible cognitive and behavioral consequences induced by low-dose radiation are important because humans are exposed to ionizing radiation from various sources. Early transcriptional response in murine brain to low-dose X-rays (100 mGy) has been reported, suggesting alterations of molecular networks and pathways associated with cognitive functions, advanced aging and AD. To investigate acute and late transcriptional, pathological and cognitive consequences of low-dose radiation, we applied an acute dose of 100-mGy total body irradiation (TBI) with X-rays to C57BL/6J Jms mice. We collected hippocampi and analyzed expression of 84 AD-related genes. Mouse learning ability and memory were assessed with the Morris water maze test. We performed in vivo PET scans with 11C-PIB, a radiolabeled ligand for amyloid imaging, to detect fibrillary amyloid beta peptide (Aβ) accumulation, and examined characteristic AD pathologies with immunohistochemical staining of amyloid precursor protein (APP), Aβ, tau and phosphorylated tau (p-tau). mRNA studies showed significant downregulation of only two of 84 AD-related genes, Apbb1 and Lrp1, at 4 h after irradiation, and of only one gene, Il1α, at 1 year after irradiation. Spatial learning ability and memory were not significantly affected at 1 or 2 years after irradiation. No induction of amyloid fibrillogenesis or changes in APP, Aβ, tau, or p-tau expression was detected at 4 months or 2 years after irradiation. TBI induced early or late transcriptional alteration in only a few AD-related genes but did not significantly affect spatial learning, memory or AD-like pathological change in mice. PMID:23908553

    The cause and progression of Alzheimer's disease (AD) are poorly understood. Possible cognitive and behavioral consequences induced by low-dose radiation are important because humans are exposed to ionizing radiation from various sources. Early transcriptional response in murine brain to low-dose X-rays (100 mGy) has been reported, suggesting alterations of molecular networks and pathways associated with cognitive functions, advanced aging and AD. To investigate acute and late transcriptional, pathological and cognitive consequences of low-dose radiation, we applied an acute dose of 100-mGy total body irradiation (TBI) with X-rays to C57BL/6J Jms mice. We collected hippocampi and analyzed expression of 84 AD-related genes. Mouse learning ability and memory were assessed with the Morris water maze test. We performed in vivo PET scans with (11)C-PIB, a radiolabeled ligand for amyloid imaging, to detect fibrillary amyloid beta peptide (Aβ) accumulation, and examined characteristic AD pathologies with immunohistochemical staining of amyloid precursor protein (APP), Aβ, tau and phosphorylated tau (p-tau). mRNA studies showed significant downregulation of only two of 84 AD-related genes, Apbb1 and Lrp1, at 4 h after irradiation, and of only one gene, Il1α, at 1 year after irradiation.

    2013-10-10

    We present research on the morphologies, spectra, and environments of ≈2350 'green valley' galaxies at 0.2 < z < 1.0 in the COSMOS field. The bimodality of dust-corrected NUV–r {sup +} color is used to define 'green valley'; it removes dusty star-forming galaxies from galaxies that are truly transitioning between the blue cloud and the red sequence. Morphological parameters of green galaxies are intermediate between those of blue and red galaxy populations, both on the Gini-asymmetry and the Gini-M{sub 20} planes. Approximately 60%-70% of green disk galaxies have intermediate or big bulges, and only 5%-10% are pure disk systems, based on morphological classification using the Zurich Estimator of Structural Types. The obtained average spectra of green galaxies are intermediate between blue and red ones in terms of [O II], Hα, and Hβ emission lines. Stellar population synthesis on the average spectra shows that green galaxies are on average older than blue galaxies but younger than red galaxies. Green galaxies and blue galaxies have similar projected galaxy density (Σ{sub 10}) distributions at z > 0.7. At z < 0.7, the fractions of M{sub *} < 10{sup 10.0} M{sub ☉} green galaxies located in a dense environment are found to be significantly larger than those of blue galaxies. The morphological and spectral properties of green galaxies are consistent with the transitioning population between the blue cloud and the red sequence. The possible mechanisms for quenching star formation activities in green galaxies are discussed. The importance of active galactic nucleus feedback cannot be well constrained in our study. Finally, our findings suggest that environmental conditions, most likely starvation and harassment, significantly affect the transformation of M{sub *} < 10{sup 10.0} M{sub ☉} blue galaxies into red galaxies, especially at z < 0.5.

  19. Comparison of separations of fatty acids from fish products using a 30-m Supelcowax-10 and a 100-m SP-2560 column.

    Commercial fish oils and foods containing fish may contain trans and/or isomerized fatty acids (FA) produced during processing or as part of prepared foods. The current American Oil Chemists' Society (AOCS) official method for marine oils (method Ce 1i-07) is based on separation by use of poly(ethylene glycol) (PEG) columns, for example Supelcowax-10 or equivalent, which do not resolve most unsaturated FA geometric isomers. Highly polar 100-m cyanopropyl siloxane (CPS) columns, for example SP-2560 and CP Sil 88 are recommended for separation of geometric FA isomers. Complementary separations were achieved by use of two different elution temperature programs with the same CPS column. This study is the first direct comparison of the separations achieved by use of 30-m Supelcowax-10 and 100-m SP-2560 columns for fatty acid methyl esters (FAME) prepared from the same fish oil and fish muscle sample. To simplify the identification of the FA in these fish samples, FA were fractionated on the basis of the number and type of double bonds by silver-ion solid-phase extraction (Ag⁺-SPE) before GC analysis. The results showed that a combination of the three GC separations was necessary to resolve and identify most of the unsaturated FA, FA isomers, and other components of fish products, for example phytanic and phytenic acids. Equivalent chain length (ECL) values of most FAME in fish were calculated from the separations achieved by use of both GC columns; the values obtained were shown to be consistent with previously reported values for the Supelcowax-10 column. ECL values were also calculated for the FA separated on the SP-2560 column. The calculated ECL values were equally valid under isothermal and temperature-programmed elution GC conditions, and were valuable for confirmation of the identity of several unsaturated FAME in the fish samples. When analyzing commercially prepared fish foods, deodorized marine oils, or foods fortified with marine oils it is strongly

    An inter-comparison of 10 mH and 100 mH inductance standards has taken place within the framework of COOMET. The inter-comparison, piloted by State Enterprise 'Ukrmetrteststandard'-UMTS (Ukraine), has involved four laboratories, including one who is a member of another regional metrological organization - EURAMET (GUM, Poland). The results presented in this report show that there are significant differences between some laboratory representations of the henry. However, the agreement demonstrated by the inter-comparison provides confidence in maintaining traceability for the henry.

    In this work, the authors are concerned by the amplification of broad-band energetic pulses in laser-pumped Nd:glasses, with obvious applications to ultrashort pulse technology, but also to a front end for the envisioned Megajoules Nd:glass laser facility devoted to inertial confinement fusion (ICF) studies and ignition demonstration. An alexandrite laser is used to longitudinally end-pump mixed Nd:glass rods in a multipass arrangement in order to amplify chirped pulses in the 50--100-mJ range at a 1-Hz repetition rate. This system has a broad-band capability of up to 8--10 nm output bandwidth. The authors have developed a model, which in the specific case of amplification of chirped-pulse, takes into account the exact configuration of the rods, their spectral properties, and the longitudinal pumping geometry. An agreement between experiment and theory is obtained by assuming a pump quantum efficiency of the order of 60%.

    A 100 m long six-filament MgB2 wire was successfully fabricated using an internal magnesium diffusion (IMD) process. We investigated the transport properties and the uniformity of this long multifilament IMD wire. The MgB2 layer and the sub-filament region are regular, and the J c values have a fairly homogenous distribution throughout the wire, suggesting that there were no obvious defects along the length of the wire. The uniformity problem of long multifilament IMD MgB2 wires can be mitigated by optimizing the starting composite parameters, multifilament geometry, fabricating process and annealing conditions. A layer J c as high as 1.2 × 105 A cm-2 at 4.2 K and 8 T was obtained, which was comparable with the highest reported value for a short multifilament IMD wire. The transport layer J c, non-barrier J c and J e values are independent of the wire diameter. In addition, the analysis of the stress-strain characteristics and the n value of the IMD wire is also presented. These results indicate that the long multifilament IMD-processed MgB2 superconducting wire is suitable for practical applications.

    Subacute and chronic mountain sickness of humans and the related brisket disease of cattle are characterized by right-sided congestive heart failure in individuals living at high altitudes as a result of sustained hypoxic pulmonary hypertension. Adaptations to high altitude and disease resistance vary among species, breeds, and individuals. The authors conducted a retrospective survey of right-sided cardiac hypertrophy associated with pulmonary arterial hypertrophy or arteriosclerosis in zoo mammals housed at Africam Safari (Puebla, México), which is located at 2,100 m above sea level. Seventeen animals with detailed pathology records matched the study criterion. Included were 10 maras (Dolichotis patagonum), 2 cotton-top tamarins (Saguinus oedipus oedipus), 2 capybaras (Hydrochaeris hydrochaeris), and 1 case each of Bennet's wallaby (Macropus rufogriseus), nilgai antelope (Boselaphus tragocamelus), and scimitar-horned oryx (Oryx dammah). All had right-sided cardiac hypertrophy and a variety of arterial lesions restricted to the pulmonary circulation and causing arterial thickening with narrowing of the arterial lumen. Arterial lesions most often consisted of medial hypertrophy or hyperplasia of small and medium-sized pulmonary arteries. All maras also had single or multiple elevated plaques in the pulmonary arterial trunk consisting of fibrosis, accompanied by chondroid metaplasia in some cases. Both antelopes were juvenile and died with right-sided congestive heart failure associated with severe pulmonary arterial lesions. To the authors' knowledge, this is the first description of cardiac and pulmonary arterial disease in zoo mammals housed at high altitudes.

    It was investigated whether skeletal muscle K(+) release is linked to the degree of anaerobic energy production. Six subjects performed an incremental bicycle exercise test in normoxic and hypoxic conditions prior to and after 2 and 8 wk of acclimatization to 4,100 m. The highest workload completed by all subjects in all trials was 260 W. With acute hypoxic exposure prior to acclimatization, venous plasma [K(+)] was lower (P < 0.05) in normoxia (4.9 +/- 0.1 mM) than hypoxia (5.2 +/- 0.2 mM) at 260 W, but similar at exhaustion, which occurred at 400 +/- 9 W and 307 +/- 7 W (P < 0.05), respectively. At the same absolute exercise intensity, leg net K(+) release was unaffected by hypoxic exposure independent of acclimatization. After 8 wk of acclimatization, no difference existed in venous plasma [K(+)] between the normoxic and hypoxic trial, either at submaximal intensities or at exhaustion (360 +/- 14 W vs. 313 +/- 8 W; P < 0.05). At the same absolute exercise intensity, leg net K(+) release was less (P < 0.001) than prior to acclimatization and reached negative values in both hypoxic and normoxic conditions after acclimatization. Moreover, the reduction in plasma volume during exercise relative to rest was less (P < 0.01) in normoxic than hypoxic conditions, irrespective of the degree of acclimatization (at 260 W prior to acclimatization: -4.9 +/- 0.8% in normoxia and -10.0 +/- 0.4% in hypoxia). It is concluded that leg net K(+) release is unrelated to anaerobic energy production and that acclimatization reduces leg net K(+) release during exercise.

    We aimed to test effects of altitude acclimatization on pulmonary gas exchange at maximal exercise. Six lowlanders were studied at sea level, in acute hypoxia (AH), and after 2 and 8 wk of acclimatization to 4,100 m (2W and 8W) and compared with Aymara high-altitude natives residing at this altitude. As expected, alveolar Po2 was reduced during AH but increased gradually during acclimatization (61 +/- 0.7, 69 +/- 0.9, and 72 +/- 1.4 mmHg in AH, 2W, and 8W, respectively), reaching values significantly higher than in Aymaras (67 +/- 0.6 mmHg). Arterial Po2 (PaO2) also decreased during exercise in AH but increased significantly with acclimatization (51 +/- 1.1, 58 +/- 1.7, and 62 +/- 1.6 mmHg in AH, 2W, and 8W, respectively). PaO2 in lowlanders reached levels that were not different from those in high-altitude natives (66 +/- 1.2 mmHg). Arterial O2 saturation (SaO2) decreased during maximum exercise compared with rest in AH and after 2W and 8W: 73.3 +/- 1.4, 76.9 +/- 1.7, and 79.3 +/- 1.6%, respectively. After 8W, SaO2 in lowlanders was not significantly different from that in Aymaras (82.7 +/- 1%). An improved pulmonary gas exchange with acclimatization was evidenced by a decreased ventilatory equivalent of O2 after 8W: 59 +/- 4, 58 +/- 4, and 52 +/- 4 l x min x l O2(-1), respectively. The ventilatory equivalent of O2 reached levels not different from that of Aymaras (51 +/- 3 l x min x l O2(-1)). However, increases in exercise alveolar Po2 and PaO2 with acclimatization had no net effect on alveolar-arterial Po2 difference in lowlanders (10 +/- 1.3, 11 +/- 1.5, and 10 +/- 2.1 mmHg in AH, 2W, and 8W, respectively), which remained significantly higher than in Aymaras (1 +/- 1.4 mmHg). In conclusion, lowlanders substantially improve pulmonary gas exchange with acclimatization, but even acclimatization for 8 wk is insufficient to achieve levels reached by high-altitude natives.

    The economic effects of Bahrain's schemes for licensing offshore banking units (OBUs) were the immediate response of major international banks and the financial services the banking center has rendered by improving regional money and exchange markets at a time when a Middle East link was needed to service the increasing demand for oil-wealth banking services. Bahrain's leadership also created a favorable climate. Aggressive competition from banks in Kuwait and Saudi Arabia have caused some friction, but informal supervision by the Bahrain Monetary Agency (BMA) should be able to avoid serious difficulty. Bahrain's success required a banking infrastructure, a free-enterprise system, a willingness to maintain banking standards, a country small enough to benefit directly from OBU income, and a gap in nearby competing centers. 39 references, 1 figure, 5 tables.

    2003-04-01

    The protozoan pathogen Cryptosporidium parvum is a leading cause of waterborne disease. Many surface water systems therefore depend on filtration systems, including bank filtration systems, for the removal of the pathogenic oocysts. To better understand the effectiveness, e.g., of bank filtration systems, we have implemented a series of columns studies under various environmental conditions (column length: 10 cm - 60 cm, flow rates: 0.7 m/d - 30 m/d, ionic strength: 0.01 - 100 mM, filter grain size: 0.2 - 2 mm, various solution chemistry). We show that classic colloid filtration theory is a reasonable tool for predicting the initial breakthrough of C. parvum in pulsed injections of the oocyst through sand columns, although the model does not account for the significant tailing that occurs in C. parvum transport. Application of colloid filtration theory to bank filtration system is further limited by the intrinsic heterogeneity of the geologic systems used for bank filtration. We couple filtration theory with a stochastic subsurface transport approach and with percolation theory to account for the effects of intrinsic heterogeneity. We find that a 1-log removal can be achieved even under relatively adverse conditions (low collision efficiency, high velocity) if 85% - 90% of the sedimentary hydrofacies located within the bank filtration system or of the coarsest known hydrofacies connecting the riverbed with the extraction system has a grain-size distribution with a 10% passing diameter equal to 1 mm. One millimeter is a standard sieve size in sediment analysis.

    Bank filtrated water has been used in developed countries such as United States, France, Germany, Austria, Nederland and so on. In Korea, most of the drinking water is provided from the surface water. However, drinking water acquisition is becoming difficult due to the degradation of surface water quality. In special, the quality of drinking water source is much lower in downstream area than in upstream area. Thus, the use of bank filtrated water is getting attracted by central and local governments in Korea. The bank filtrated water was surveyed in the areas of Yeongsan river, Nakdong river, Geum river and Han river. Up to present, however, the downstream areas of Nakdong river are most suitable places to apply the bank filtration system. This study investigates hydrogeological characteristics of bank-storage area located in Daesan- Myeon, Changwon city, adjacent the downstream of Nakdong river. Changwon city is the capital city of Gyeongsangnam-Do province. Changwon city uses water derived from Nakdong river as municipal water. However, the quantity and quality of the river water are gradually decreased. Thus, Changwon city developed two sites of bank filtration system in Daesan-myeon and Buk-myeon. Pumping rate is 2,000m3/day at present and will be increased to 60,000m3/day in Daesan-myeon site at the end of the first stage of the project. For the study, we conducted pumping tests four times on seven pumping wells (PW1, PW2, PW3, PW4, PW5, PW6, and PW7) and twelve drill holes (BH-2, OW2-OW12) in the area of 370 m x 100 m. Pumping wells PW1 and PW2 were drilled in 1999 by Samjung Engineering Co. and pumping wells PW3, PW4, PW5, PW6 and PW7 were drilled in 2000 by Donga Construction Co. and Daeduk Gongyeong Co. The pumping wells are located at 45-110 meters from Nakdong riverside. The geology of the study area is composed of volcanic rocks (Palryeongsan tuff and Jusasan andesitic rock) and alluvium.

    By a {open_quotes}tree-bank grammar{close_quotes} we mean a context-free grammar created by reading the production rules directly from hand-parsed sentences in a tree bank. Common wisdom has it that such grammars do not perform well, though we know of no published data on the issue. The primary purpose of this paper is to show that the common wisdom is wrong. In particular, we present results on a tree-bank grammar based on the Penn Wall Street Journal tree bank. To the best of our knowledge, this grammar outperforms all other non-word-based statistical parsers/grammars on this corpus. That is, it outperforms parsers that consider the input as a string of tags and ignore the actual words of the corpus.

    National University Hospital Tissue Bank protocol follows guidelines recommended by the American Association of Tissue Banks and the European Association of Tissue Banks using donor selection criteria: medical history, clinical examination, chart review and laboratory tests for acquired immunodeficiency syndrome (AIDS), hepatitis B, hepatitis C, syphilis, and specimen for culture/sensitivity tests. For living donors, repeat testing is performed for AIDS and hepatitis C approximately 180 days after procurement. Femoral heads are procured using the "sterile double jar technique" and stored at -80 degrees C. Our first study of 273 consecutive potential donors undergoing hemiarthroplasty from 1989 to 1994 showed that a high percentage (42.5%) was unsuitable for use. A second study involving 175 potential donors was conducted from 1995 to 2003 after hepatitis C screening was introduced. The bacterial contamination rates in both studies (3.5% and 5.7%) are low. The incidence of other diseases also are low: hepatitis B, 2.3% and syphilis, 1.8% in the first study and hepatitis B, 5.7%; hepatitis C, 0.6%; and syphilis, 5.1% in the second cohort. No cases of AIDS were reported in either study. By 2003, femoral heads were transplanted in 205 patients with a low complication rate of 2.9%.

    Evidence of the impact of green spaces on pregnancy outcomes is limited with no report on how this impact might vary by ethnicity. We investigated the association between residential surrounding greenness and proximity to green spaces and birth weight and explored the modification of this association by ethnicity and indicators of individual (maternal education) and neighbourhood (Index of Multiple Deprivation) socioeconomic status. Our study was based on 10,780 singleton live-births from the Born in Bradford cohort, UK (2007-2010). We defined residential surrounding greenness as average of satellite-based Normalized Difference Vegetation Index (NDVI) in buffers of 50 m, 100 m, 250 m, 500 m and 1000 m around each maternal home address. Residential proximity to green spaces was defined as living within 300 m of a green space with an area of ≥ 5000 m(2). We utilized mixed effects models to estimate adjusted change in birth weight associated with residential surrounding greenness as well as proximity to green spaces. We found a positive association between birth weight and residential surrounding greenness. Furthermore, we observed an interaction between ethnicity and residential surrounding greenness in that for White British participants there was a positive association between birth weight and residential surrounding greenness whereas for participants of Pakistani origin there was no such an association. For surrounding greenness in larger buffers (500 m and 1000 m) there were some indications of stronger associations for participants with lower education and those living in more deprived neighbourhoods which were not replicated for surrounding greenness in smaller buffer sizes (i.e. 50 m, 100 m, and 250 m). The findings for residential proximity to a green space were not conclusive. Our study showed that residential surrounding greenness is associated with better foetal growth and this association could vary between different ethnic and socioeconomic groups.

    Human milk banks play an essential role by providing human milk to infants who would otherwise not be able to receive human milk. The largest group of recipients are premature infants who derive very substantial benefits from it. Human milk protects premature infants from necrotizing enterocolitis and from sepsis, two devastating medical conditions. Milk banks collect, screen, store, process, and distribute human milk. Donating women usually nurse their own infants and have a milk supply that exceeds their own infants' needs. Donor women are carefully selected and are screened for HIV-1, HIV-2, human T-cell leukemia virus 1 and 2, hepatitis B, hepatitis C, and syphilis. In the milk bank, handling, storing, processing, pooling, and bacterial screening follow standardized algorithms. Heat treatment of human milk diminishes anti-infective properties, cellular components, growth factors, and nutrients. However, the beneficial effects of donor milk remain significant and donor milk is still highly preferable in comparison to formula.

    The East Flower Garden Bank (EFGB), part of the Flower Garden Banks National Marine Sanctuary, is located in the northwestern Gulf of Mexico, about 185 km southeast of Galveston, Texas. With a width of about 5 km, the steep-sided bank rises from water depths of over 100 m to within less than 20 m of the surface. Four acoustic Doppler current profiler (ADCP) moorings and four temperature/salinity strings were deployed around the EFGB with an additional ADCP on top of the bank for about 1 year. The main objective was to understand the ocean processes over the EFGB and to examine the importance of the topographically induced processes on shelf edge circulation on longer (e.g. days to seasonal) time scales. Currents were generally eastward over the bank in the upper water column. Eddy events occasionally reversed the eastward flow for a few days. Currents in the lower water column tended to align with the bank's bathymetry and mostly were directed offshore at the southern edge of the bank. Wind and eddy events moved both shelf and off-shelf waters over the bank, including waters from as deep as 200 m through upwelling and/or mixing processes. Mixed layers changed by as much as 50 m in a couple of days. Inertial currents occurred throughout the year and were often much larger than the tidal currents. Commonly, the inertial currents were strong enough to reverse the predominantly eastward current flow on time scales of less than a day. Westward propagating cyclonic eddies (often associated with anticyclonic eddies) likely connect biological activities of the EFGB with the West Flower Garden Bank. Banks such as the EFGB, with large aspect ratios and heights, strongly alter circulation and enhance exchange processes at the shelf break.

    NASA Astrophysics Data System (ADS)

    Phipps, C. V. G.; Roberts, H. H.

    1988-03-01

    Extensive areas of Halimeda bioherms similar to those described by Orme et al. (1978), Orme (1985), Davies and Marshall (1985), and Phipps et al. (1985) from Australia's Great Barrier Reef have formed on Kalukalukuang Bank (K-Bank) 50 km east of the Sunda Shelf margin in the easter Java Sea. K-Bank is an isolated limestone platform whose top slopes southward from a water depth of about 20 m at the north to about 100 m at the south (≈30 km). It occurs in a bidirectional monsoonal wind regime and a predominantly southerly flowing current from Makassar Strait. The water column around K-Bank has a well developed shallow thermocline (50 m to 150 m). K-Bank has a relatively flat top with marginal banks of suspected Pleistocene origin as interpreted from seismic relationships. A reconnaissancelevel survey grid of high-resolution seismic profiles indicates that Halimeda bioherms are restricted to the bank margins with the exception of the eastern margin. Bioherms either extend to the steep margin of the platforms or are separated from the platform edge by banks of coral and coralline algae. The morphology of the Halimeda bioherms varies from steep-sided, elongate ridges in the northern bank area, through coalescing symmetrical mounds with partly infilled valleys, to broad undulating areas similar to those described by Orme (1985) from the Great Barrier Reef. High-resolution seismic records indicate erosional episodes in the high-relief areas, an interpretation that seems to be supported by accumulation rates calculated from C14 dates of cores. Thicknesses of Halimeda accumulation above a prominent reflector considered as Pleitocene, vary from around 20 m in the north to a maximum of over 50 m in the southwest. Accumulation rates obtained from dating of two cores to-ward the north of K-Bank, average 0.294 m/100 yr for core VC4 and a maximum of 0.59 m/100 yr in a part of core PC12.

    Forms of human milk banking and donation have been present for more than a century worldwide, but, since 1985, the Human Milk Banking Association of North America (HM BANA) has established guidelines to make the use of donor's breast milk safe and the second best form of feeding to maternal breast milk for a neonatal intensive care unit (NICU) infant. The Indiana Mother's Human Milk Bank provides an extensive and meticulous process of selecting breast milk donors. The process begins with a phone interview with a potential donor and includes the review of the donor's medical records, blood laboratory screening, medication and dietary intake, as well as consent from the donor's pediatrician. The milk bank follows steps of collecting, storing, and receiving the breast milk in accordance with the guidelines of the HM BANA. Pasteurization is the method used to ensure the proper heating and cooling of breast milk. Despite the rigorous pasteurization method, the donor's breast milk will not lose most of the important beneficial components needed for sick or ill NICU infants. Every batch of pasteurized breast milk will be cultured for any possible contamination and shipped to NICUs after it has been cleared by laboratory testing.

  2. Cord blood banking.

    Cord blood (CB) is a unique product, rich in haemopoietic stem cells (HSC), that is currently used in the transplantation setting to restore haemopoiesis. It restores haemopoietic stem cell function in patients suffering from malignancies, bone marrow (BM) failure disorders and inherited metabolic and immunological disorders. Related and unrelated CB donations have been successfully transplanted in both the paediatric and adult settings. CB, previously considered a waste product, can be collected from both vaginal deliveries and caesarean sections, either in utero or ex utero, at no risk to the donor, processed to remove excess plasma and red cells, cryopreserved, tested, HLA-typed and stored to provide an 'off-the-shelf' product. CB has a lower risk of some important viral infections and a lower incidence and severity of acute and chronic graft versus host disease (GvHD) than BM. CB transplantation is under innovative development and international collaborative studies are investigating ways to improve transplant outcomes. Other uses for CB remain speculative and it is premature to speculate whether non-haemopoietic stem cells are present in cord blood in sufficient numbers for use against degenerative conditions, as is currently postulated by some commercial organisations. Cord blood banking in EU member countries is now regulated by an EU Directive, which provides a statutory basis for regulation safety to ensure efficacy. Compliance is required by 2006. It requires that all banking establishments are inspected and accredited by a Competent Authority. This includes public altruistic banking as well as directed banking activities.

    Transplantation of cord blood stem cells is a new and rapidly developing area. It has been used as a treatment for many diseases such as hematologic malignancies, primary immune deficiencies and metabolic diseases. Recently, stem cells have been used in regenerative medicine, particularly in neurodegenerative and cardiovascular diseases. For these reasons interest has been growing in banking cord blood. To be able to find an acceptable donor for any recipient in need, it is necessary to have on stock a great diversity of cells with different genetic types from different populations. Networks of banks and registries have been created around the world in order to share and exchange transplants. Public banks organize collection for altruistic donor of cord blood for unrelated hematopoietic stem cell transplantation and for directed donation in families at risk. But there are increasing numbers of families that are requesting storage of cord blood for possible future therapeutic use in the family. Establishment of cord blood banks has raised a number of important scientific, legal, ethical and political issues, which are discussed in this paper.

  13. Banking on women's spirit.

    PubMed

    Yunus, M

    1993-11-01

    An interview with Professor Mummadad Yunus, Managing Director of the Grameen Bank, revealed that he has provided loans to poor women in Bangladesh since 1976 and that the Grameen Bank has continued his work since 1983. The idea behind the banking system is that poor people without traditionally accepted collateral are good credit risks. In 1993, the Grameen Bank had operations in 33,000 out of a possible 68,000 villages in Bangladesh. The operations include 1030 branches and a staff of 12,000 people. 1.6 million people are recipients of loans, of whom 94% are women. The population served is the poorest and has no experience in income generation. Conclusions drawn from this experience are that women are better managers of resources and are more serious entrepreneurs than men and that the benefits of loan programs for the poor go directly to children and households. Women's self-image suffers from negative social conceptions, and one task is to convince women of their value, skills, and possibility of advancement. The bank philosophy rests with the belief that all human beings are a "treasure of potential possibilities." Women are advised to protect their money and marriage and not to sacrifice one for the other. Husbands initially are against money going to wives, but eventually they understand that the family benefits. Over 200,000 loans have been made for the provision of housing. The loan requirement is that the woman must own the land on which the house is built. Husband's have the opportunity to transfer title of the land to the wife. Ownership of land provides security for the wife.

  15. Disturbance Rejection Control for The Green Bank Telescope

    NASA Astrophysics Data System (ADS)

    Ranka, Trupti

    The GBT is a single dish, receiving radio telescope. It is capable of receiving radio waves in the frequency range of 300 MHz to 115 GHz. The off-axis primary reflector of the telescope is 100 meters in diameter. A truss boom (feedarm) extends about 60 meters perpendicular to the primary reflector and is supported at the edge of the reflector. A subreflector is placed at the tip of the feedarm, which directs the focused radio waves from the primary reflector to the radio receivers placed on the feedarm. At high radio frequencies of observation, the uncorrected pointing and tracking errors become limiting factors for making useful scientific observations. The primary reflector and subreflector servo systems need to reduce the pointing and tracking errors due to torque disturbances acting on the system. The overall aim of this research is to redesign the servo control systems such that they are able to give a superior disturbance rejection performance. The 4 contributions of this research are: 1) Verifying the dynamical model of the structure using system identification experiments. 2) The unique reformulation of the extended state observer (ESO) design as a quantitative feedback design problem in frequency domain and splitting the design of the ESO as a feedback observer and a feedforward filter. This formulation gives a more systematic way of designing an ESO as compared to the current technique used for the ESO design. This method is then used to design the ESO based controller for the primary reflector position loop. The ESO based controller provides more than 50% improvement in disturbance rejection in the primary reflector servo loop, as compared to the legacy PID controller. 3) The innovative use of extremum seeking controller (ESC) with a disturbance feedforward signal. We investigate the use of disturbance feedforward with ESC and show that disturbance feedforward improves the speed of the ESC loop by improving the initial condition of the ESC loop and by reducing the magnitude of the error dynamics. 4) The formulation of the subreflector control as an extremum seeking problem, and using the ESC with disturbance feedforward for the subreflector control. This method gives more than 40% improvement in the tracking of a point source against feedarm swaying in wind gusts.

  5. Corneal grafting and banking.

    Ehlers, Niels; Hjortdal, Jesper; Nielsen, Kim

    2009-01-01

    Corneal transplantation was conceptualized at the end of the 18th century, but it took more than 100 years before human corneal grafting was introduced. The greatest step forward was the demonstration by Filatov that corneal tissue can be collected and used post mortem. The history of eye banking includes the development of preservation techniques. Storage in cold to minimize microbial growth and tissue disintegration was first choice but during the last 30 years this has been taken over by warm storage (organ culture) where the donor cornea proves its sterility and vitality before being transferred to the recipient. The long-term organ culture storage makes exchange between centres possible and allows for histocompatibility matching. The internationalization led to the establishing of the European Eye Bank Association but also to an increasing number of governmental regulations. Developments in years to come may lead to control of graft biomechanics and optics. This technical development tends to favour a centralization.

    At the University of Colorado, Dr. Gordon Meiklejohn pursed the study of influenza and other respiratory pathogens for an unbroken period of 40 years, under the auspices of the Commission on Influenza of the Armed Forces Epidemiological Board through a series of contracts with the U.S. Army Medical Research and Development Command. Sera, throat washings, and other specimens for diagnosis were sent to Dr. Meiklejohn's laboratory. After serologic and virologic studies were carried out, aliquots of sera and virus samples were logged in and frozen. Sera were stored at -20°C and virus specimens at -70°C. These specimens became known as the Denver Serum Bank. The Bank supported military research programs and other researchers nationally and internationally until the 1990s when lacking of funding and considerations of administration, space, and cost resulted in the destruction of all specimens.

    We define as Banking of the tissues all the procedures that include the finding, preparation, conservation and distribution of the homograft. The vascular homografts are taken and put into a solution of transportation at +4 degrees C and kept at this temperature till their arrival at the Bank. The following step is the dissection of the homograft which will have to be performed as quickly as possible at most 24 hours after the taking in conditions of maximum sterility. At the Italian Homograft Bank at Centro Cardiologico, the vascular homografts are kept at +4 degrees C for 96 hours on average with antibiotics. After a phase of sterilization at +4 degrees C the tissue is frozen according to a homogeneous and controlled thermic decrease and stored at -150 degrees C/-180 degrees C in fumes of liquid nitrogen till the moment of their employment allowing a long term conservation. The aim of all these procedures of cryopreservation is to keep the structural and functional integrity of cells and tissues. The thermic decrease of the tissues must occur so that to avoid all the damages of the cellular vitality and functionality and especially of the tissue structure in toto. In order to limitate these events some cryoprotector agents are employed because they reduce the concentration of the solutes, the cellular dehydration, the formation of micro-macro crystals. Another step to establish if the homograft is proper is the study of bacteriological and viral aspects. The viral screenings are performed on the donor's blood and the bacteriological tests are performed on the tissue and on the liquids. For each phase of the banking a series of information about the donor and about the tissues are recorded and filed both on paper and database so that to grant always a right conduct of the material.

    Virtual blood bank is the computer-controlled, electronically linked information management system that allows online ordering and real-time, remote delivery of blood for transfusion. It connects the site of testing to the point of care at a remote site in a real-time fashion with networked computers thus maintaining the integrity of immunohematology test results. It has taken the advantages of information and communication technologies to ensure the accuracy of patient, specimen and blood component identification and to enhance personnel traceability and system security. The built-in logics and process constraints in the design of the virtual blood bank can guide the selection of appropriate blood and minimize transfusion risk. The quality of blood inventory is ascertained and monitored, and an audit trail for critical procedures in the transfusion process is provided by the paperless system. Thus, the virtual blood bank can help ensure that the right patient receives the right amount of the right blood component at the right time.

    Nanotechnology, in particular nanophotonics, is proving essential to achieving green outcomes of sustainability and renewable energy at the scales needed. Coatings, composites and polymeric structures used in windows, roof and wall coatings, energy storage, insulation and other components in energy efficient buildings will increasingly involve nanostructure, as will solar cells. Nanostructures have the potential to revolutionize thermoelectric power and may one day provide efficient refrigerant free cooling. Nanomaterials enable optimization of optical, opto-electrical and thermal responses to this urgent task. Optical harmonization of material responses to environmental energy flows involves (i) large changes in spectral response over limited wavelength bands (ii) tailoring to environmental dynamics. The latter includes engineering angle of incidence dependencies and switchable (or chromogenic) responses. Nanomaterials can be made at sufficient scale and low enough cost to be both economic and to have a high impact on a short time scale. Issues to be addressed include human safety and property changes induced during manufacture, handling and outdoor use. Unexpected bonuses have arisen in this work, for example the savings and environmental benefits of cool roofs extend beyond the more obvious benefit of reduced heat flows from the roof into the building.

    Analysis of organic compounds in samples characterized by different composition of the matrix is very important in many areas. A vast majority of organic compound determinations are performed using gas or liquid chromatographic methods. It is thus very important that these methods have negligible environmental impact. Chromatographic techniques have the potential to be greener at all steps of the analysis, from sample collection and preparation to separation and final determination. The paper summarizes the approaches used to accomplish the goals of green chromatography. While complete elimination of sample preparation would be an ideal approach, it is not always practical. Solventless extraction techniques offer a very good alternative. Where solvents must be used, the focus should be on the minimization of their consumption. The approaches used to make chromatographic separations greener differ depending on the type of chromatography. In gas chromatography it is advisable to move away from using helium as the carrier gas because it is a non-renewable resource. GC separations using low thermal mass technology can be greener because of energy savings offered by this technology. In liquid chromatography the focus should be on the reduction of solvent consumption and replacement of toxic and environmentally hazardous solvents with more benign alternatives. Multidimensional separation techniques have the potential to make the analysis greener in both GC and LC. The environmental impact of the method is often determined by the location of the instrument with respect to the sample collection point.

    Soil seed bank consists of all living seeds existed in soil and its surface litter, especially in topsoil, and can reflect the characteristics of regional biodiversity. As the base of vegetation restoration and potential greening material, topsoil and its seed bank are the limited and non-renewable resources in mining areas. The study of soil seed bank has become one of the hotspots in the research field of vegetation restoration and land reclamation in China mining areas. Owing to the special characteristics of mining industry, the soil seed bank study of mining areas should not only concern with the seed species, quantities, and their relations with ground surface vegetation, but also make use of the research results on the soil seed bank of other fragile habitats. Besides, a breakthrough should be sought in the thinking ways and research approach. This paper analyzed the particularity of mining area's soil seek bank research, summarized the research progress in the soil seed bank of mining areas and other fragile habitats, and put forward the challenges we are facing with. It was expected that this paper could help to reinforce the soil seed bank research of China mining areas, and provide scientific guidelines for taking great advantage of the significant roles of soil seed bank in land reclamation and vegetation restoration in the future.

  1. Umbilical cord blood banks. Ethical aspects. Public versus private banks.

    PubMed

    Aznar Lucea, Justo

    2012-01-01

    The creation of umbilical cord blood (UCB) banks raises interesting medical, social, economic and ethical issues. This paper reviews the ethical problems specifically. In this respect, it evaluates: a) whether there are advantages to the use of UCB compared to bone marrow, b) whether or not it is ethical to create UCB banks, c) whether their creation is ethically acceptable in terms of their clinical usefulness or d) the use made of them for therapeutic purposes, and finally e) whether their creation is ethically justified from a cost/profitability point of view. We focus primarily on evaluating the ethical controversy between public and private banks, particularly on whether it is ethical to bank autologous blood in private UCB banks, on the basis of its limited possibilities for use by the cord blood donor. We can conclude that, from an ethical point of view, autologous blood banks have limited acceptance among specialised researchers, scientific societies and other public institutions. Therefore, we believe that it is ethically more acceptable to support the creation of public UCB banks for medical and social reasons and, above all, based on the principle of justice and human solidarity. Nevertheless, there is no definitive ethical argument why a couple, according to their autonomy and freedom, cannot bank their child's UCB in a private bank. An equally acceptable solution could be the creation of mixed banks, such as that proposed by the Virgin Health Bank or like the Spanish system where autologous samples can be stored in public banks but with the proviso that if at any time the stored sample is required by any person other than the donor, it would have to be given to them.

  7. Habitat usage by the cryptic copepods Pseudocalanus moultoni and P. newmani on Georges Bank (Northwest Atlantic)

    NASA Astrophysics Data System (ADS)

    Bucklin, Ann; McGillicuddy, Dennis J.; Wiebe, Peter H.; Davis, Cabell S.

    2015-12-01

    The cryptic copepod species, Pseudocalanus moultoni and P. newmani, co-occur on Georges Bank and in the Gulf of Maine (Northwest Atlantic); even recent studies have reported results and conclusions based on examination of the combined species. Species-specific PCR (SS-PCR) based on mitochondrial cytochrome oxidase I (COI) sequence divergence was used in this study to discriminate the species. Species-specific descriptions of habitat usage and predicted patterns of transport and retention on Georges Bank were made by mapping distributions and calculating abundances of each species from January to June, 1999 for four vertical strata (0-15 m, 15-40 m, 40-100 m, and 0-100 m) and five regions (Northern Flank, Bank Crest, Northeast Peak, Southern Flank, and Slope Water) identified on the basis of bathymetry and circulation. Patterns of distribution and abundance for the two species during January to June, 1999 were largely consistent with those described based on vertically integrating mapping and analysis for the same period in 1997 by McGillicuddy and Bucklin (2002). The region-specific and depth-stratified analyses allowed further discrimination in habitat usage by the species and confirmed the distinctive patterns for the two species. The observed differences between the species in abundances among the five regions and three depth strata over Georges Bank impact their transport trajectories. The concentration of P. moultoni in deep layers likely explains the higher rates of retention and lower rates of advective loss of this species from the Bank, compared to P. newmani, which may be more subject to wind-driven transport in the surface layer. Accurate identification and discrimination of even closely-related and cryptic species is needed to ensure full understanding and realistic predictions of changes in diversity of zooplankton and the functioning of pelagic ecosystems.

    Replacing a healthcare facility first opened in 1908 as a 20-bed cottage hospital, the recently opened 'new' Finchley Memorial Hospital in north-west London was designed by architects, Murphy Philipps, 'to be at the heart of a health campus', surrounded by green space for use by both the hospital itself, and the local community. The 28 million pounds hospital, which has achieved a BREAAM Excellent rating - with an annual energy target of just 35 GJ/100 m3 set by SHINE, the Department of Health-backed learning network for sustainable healthcare buildings - has also featured as one of only 20 projects in the RIBA Health Buildings Exhibition. HEJ editor, Jonathan Baillie, met with lead architect, Marc Levinson, to find out more about the key elements, and the thinking, that went into the design.

  11. [Cord blood banks].

    PubMed

    Buljan Culej, Jasminka

    2007-12-01

    Cord blood is an excellent source of stem cells which are universal for all other cells of the whole body. They have the ability to develop in any of the body cells, depending on stimulation by different growth factors. The ease of sampling, cryopreservation, and above all successful engraftment make placental blood a possible alternative for bone marrow donation. The advantages of cord blood cells over bone marrow stem cells in allogeneic transplants include their young age and immature status, which reduce the severity of graft versus host reaction. However, the number of cells is much more limited than with bone marrow (about ten time less); therefore, for the time being, the procedure is not equivalent to marrow donation. Cord blood banks would increase HLA diversity, and they are therefore expected to solve two sets of immunogenetic problems: (1) since less stringent compatibility is needed, children with a rare HLA group could benefit from a graft when the donor is not perfectly matched; and (2) HLA types infrequently represented in registries may be represented more readily in placental blood banks; although they occur repeatedly in certain ethnic groups or populations, they are only rarely donated to volunteer registries, while these populations are also concerned in transplantation. Many countries in the world have recognized the significance of collecting and preserving cord blood stem cells and their ability to heal or at least improve life.

    2012-01-01

    Background: Green spaces have been associated with improved physical and mental health; however, the available evidence on the impact of green spaces on pregnancy is scarce. Objectives: We investigated the association between surrounding greenness and birth weight, head circumference, and gestational age at delivery. Methods: This study was based on 2,393 singleton live births from four Spanish birth cohorts (Asturias, Gipuzkoa, Sabadell, and Valencia) located in two regions of the Iberian Peninsula with distinct climates and vegetation patterns (2003–2008). We defined surrounding greenness as average of satellite-based Normalized Difference Vegetation Index (NDVI) (Landsat 4–5 TM data at 30 m × 30 m resolution) during 2007 in buffers of 100 m, 250 m, and 500 m around each maternal place of residence. Separate linear mixed models with adjustment for potential confounders and a random cohort effect were used to estimate the change in birth weight, head circumference, and gestational age for 1-interquartile range increase in surrounding greenness. Results: Higher surrounding greenness was associated with increases in birth weight and head circumference [adjusted regression coefficients (95% confidence interval) of 44.2 g (20.2 g, 68.2 g) and 1.7 mm (0.5 mm, 2.9 mm) for an interquartile range increase in average NDVI within a 500-m buffer] but not gestational age. These findings were robust against the choice of the buffer size and the season of data acquisition for surrounding greenness, and when the analysis was limited to term births. Stratified analyses indicated stronger associations among children of mothers with lower education, suggesting greater benefits from surrounding greenness. Conclusions: Our findings suggest a beneficial impact of surrounding greenness on measures of fetal growth but not pregnancy length. PMID:22899599

  18. Variability of plant nitrogen and water use in a 100-m transect of a subdesertic depression of the Ebro valley (Spain) characterized by leaf δ13C and δ15N

    NASA Astrophysics Data System (ADS)

    Peñuelas, Josep; Filella, Iolanda; Terradas, Jaume

    1999-04-01

    We studied carbon and nitrogen isotopic composition ( δ13C and δ15N) in sunlit leaves of four dominant species ( Rosmarinus officinalis L., Stipa parviflora L., Juniperus thurifera L. and Pinus halepensis L.) in a characteristic gradient of water and nitrogen availability produced by relief and micrometeorology in a subdesertic valley of central-NE Spain. Minimum values of δ13C were found at the foothills, and higher values were found both in the valley and on the top of the hill where water availability was lower. However, different species (functional groups) presented different δ13C values in the same valley. The lowest values of δ15N were found on the top of the hill and the highest ones in the valley, where N losses would thus be higher. In general, when growing together, trees showed 2 % higher values for δ13C as well as for δ15N than shrubs and grasses. The specific responses show that they use different available water and nitrogen resources within small catchments. For this ecosystem type, C and N isotope analyses are sensitive enough to resolve fine spatial and functional patterns even over a very short distance (100 m), where topography generates great gradients in microclimate, hydrology, soil physical conditions, vegetation and biogeochemistry.

    2015-01-01

    The purpose of this work was to investigate whether low frequency, low intensity (LFLI, 20 kHz, <100 mW/cm2, spatial-peak, temporal-peak) ultrasound (US), delivered by a light-weight (<100g), tether-free, fully wearable, battery powered applicator is capable of reducing inflammation in a mouse model of Rheumatoid Arthritis (RA). The therapeutic, acute, anti-inflammatory effect was estimated by the relative swelling induced in mice hind limb paws. In an independent, indirect approach, the inflammation was bio-imaged by measuring glycolytic activity with near infrared labeled 2-deoxy-glucose (2DG). The outcome of the experiments indicated that the combination of US exposure with topical application of 0.1% w/w betamethasone gel, exhibited statistically significant (p<0.05) enhanced anti-inflammatory properties in comparison with the drug or US treatment alone. The present study underscores the potential benefits of LFLI US assisted drug delivery. However, the proof of concept presented indicates the need for additional experiments to systematically evaluate and optimize the potential of, and the conditions for, safe, LFLI ultrasound promoted non-invasive drug delivery.

    The present research sought to extend the nascent literature on color and psychological functioning by examining whether perception of the color green facilitates creativity. In four experiments, we demonstrated that a brief glimpse of green prior to a creativity task enhances creative performance. This green effect was observed using both achromatic (white, gray) and chromatic (red, blue) contrast colors that were carefully matched on nonhue properties, and using both picture-based and word-based assessments of creativity. Participants were not aware of the purpose of the experiment, and null effects were obtained on participants' self-reported mood and positive activation. These findings indicate that green has implications beyond aesthetics and suggest the need for sustained empirical work on the functional meaning of green.

  4. Concepts of marine specimen banking.

    PubMed

    Rossbach, M; Kniewald, G

    1997-05-01

    For more than a decade environmental specimen banking (ESB) has been an established approach for monitoring and retrospective environmental survey purposes in a number of developed countries. Specimen banking is carried out on regional or national scales for various environmental materials. The ecological or problem-oriented approach, as pursued e.g. in Germany or USA has the advantages of a restricted survey and a clear political mandate. Environmental problems, however, are by no means national or regional issues, since the diversity and dispersion of hazardous substances make environmental monitoring clearly a global affair. The structuring of our environment suggests that banking should not be limited by national boundaries, but rather be based on eco-systematic principles. Such distinct banking efforts should be devoted to the monitoring of physico-chemical aspects of climatic change and air pollution, soil quality, and aquatic monitoring on a world-wide scale. As some experience already exists with specialized banking programs for marine samples, such as the National Marine Mammal Tissue Bank or the Mussel Watch Program in the United States, an international marine specimen bank, based on principles of national ESB's, is advocated to be established in due time. Following the recommendations of the 1992 Rio 'Earth Summit' to pursue sustainable development strategies, such an establishment could strongly facilitate efforts concerning pollution control and mitigation, overexploitation and mining of ocean resources on a regional or global scale.

  2. Indocyanine green video angiography

    NASA Astrophysics Data System (ADS)

    Frambach, Donald A.

    1994-06-01

    Over the last two years, ophthalmologists have begun to use indocyanine green angiography as a supplement to fluorescein angiography. Unlike fluorescein, indocyanine green absorbs near infrared and emits slightly longer infrared light. Therefore, indocyanine green angiography images structures deeper in the retina and through blood, pigment, and turbid serous fluid that accumulates in a number of diseases. In addition, indocyanine green shows very different properties of dye leakage than does fluorescein and this can be used to identify certain abnormal blood vessels that grow beneath the retinas of patients with macular degeneration. Finally, indocyanine green fluoresces only 4% as efficiently as fluorescein which has presented a major technical problem until highly amplified video systems have become available to ophthalmologists. We have used a scanning laser ophthalmoscope to perform video indocyanine green angiography at the Doheny Eye Institute since November, 1991. In this paper, I will present several clinical cases that demonstrate the clinical usefulness of indocyanine green angiography.

    The BDB database (http://immunet.cn/bdb) is an update of the MimoDB database, which was previously described in the 2012 Nucleic Acids Research Database issue. The rebranded name BDB is short for Biopanning Data Bank, which aims to be a portal for biopanning results of the combinatorial peptide library. Last updated in July 2015, BDB contains 2904 sets of biopanning data collected from 1322 peer-reviewed papers. It contains 25 786 peptide sequences, 1704 targets, 492 known templates, 447 peptide libraries and 310 crystal structures of target-template or target-peptide complexes. All data stored in BDB were revisited, and information on peptide affinity, measurement method and procedures was added for 2298 peptides from 411 sets of biopanning data from 246 published papers. In addition, a more professional and user-friendly web interface was implemented, a more detailed help system was designed, and a new on-the-fly data visualization tool and a series of tools for data analysis were integrated. With these new data and tools made available, we expect that the BDB database would become a major resource for scholars using phage display, with improved utility for biopanning and related scientific communities.

  12. Vector computer memory bank contention

    NASA Technical Reports Server (NTRS)

    Bailey, D. H.

    1985-01-01

    A number of vector supercomputers feature very large memories. Unfortunately the large capacity memory chips that are used in these computers are much slower than the fast central processing unit (CPU) circuitry. As a result, memory bank reservation times (in CPU ticks) are much longer than on previous generations of computers. A consequence of these long reservation times is that memory bank contention is sharply increased, resulting in significantly lowered performance rates. The phenomenon of memory bank contention in vector computers is analyzed using both a Markov chain model and a Monte Carlo simulation program. The results of this analysis indicate that future generations of supercomputers must either employ much faster memory chips or else feature very large numbers of independent memory banks.

    tissues may allow future cloning to restore biodiversity. Furthermore, there would be no scientific extinction. Location: After a thorough search, it has been concluded that the gene bank containing container should be buried under the regolith of the PSR of the base of Shoemaker Crater located near the Lunar South Pole, centered at 88.1 S, 45E. It provides diameter of 20-51km with an immense 100m ^{2} of PSR. The physical properties of the floor material can be modeled. This floor is known to be flat, providing simple geometry for understanding impact dynamics and the Ejecta plume in case required. In addition, about half of the crater floor is invisible from earth but access from polar lunar orbiter is good because a spacecraft would pass overhead every two hours. Hence, it enables easy storage, surveillance and prolonged retention of the proposed gene bank. Conclusion: Cryoconservation can add an important ethical component to the space programme and help raising public support. Conversely, the permanent safety of the genetic material can also make cryoconservation itself more attractive and fundable. Many nations may wish to participate to secure the genetic heritage of their unique biota and ethnic groups. It is highly advisable that developed countries associate with biologically rich countries to collect as many as genetic samples possible which they can include in their future lunar missions to secure the future of the living world. Until habitat losses are controlled, cryoconservation may provide the best chance to secure and eventually revive many endangered species. For this purpose, space-based depositories can provide precise conservation ,the most cost-effective and secure means for permanent storage of irreplaceable genetic materials with a single one time expenditure for ages instead of the prevalent ineffective conservation programs.

  3. Cash efficiency for bank branches.

    Cabello, Julia García

    2013-01-01

    Bank liquidity management has become a major issue during the financial crisis as liquidity shortages have intensified and have put pressure on banks to diversity and improve their liquidity sources. While a significant strand of the literature concentrates on wholesale liquidity generation and on the alternative to deposit funding, the management of an inventory of cash holdings within the banks' branches is also a relevant issue as any significant improvement in cash management at the bank distribution channels may have a positive effect in reducing liquidity tensions. In this paper, we propose a simple programme of cash efficiency for the banks' branches, very easy to implement, which conform to a set of instructions to be imposed from the bank to their branches. This model proves to significantly reduce cash holdings at branches thereby providing efficiency improvements in liquidity management. The methodology we propose is based on the definition of some stochastic processes combined with renewal processes, which capture the random elements of the cash flow, before applying suitable optimization programmes to all the costs involved in cash movements. The classical issue of the Transaction Demand for the Cash and some aspects of Inventory Theory are also present. Mathematics Subject Classification (2000) C02, C60, E50.

  7. Effects of warm water intrusions on populations of macrozooplankton on Georges Bank, Northwest Atlantic

    NASA Astrophysics Data System (ADS)

    Brown, Harmon; Bollens, Stephen M.; Madin, Laurence P.; Horgan, Erich F.

    2005-01-01

    As part of the Georges Bank/North West Atlantic GLOBEC (Global Ocean Ecosystems Dynamics) Program, macrozooplankton and micronekton were collected on 30 Broad Scale Survey Cruises between January-June, 1995-1999, using a 10 m 2 MOCNESS (3 mm mesh). The objective of this study is to examine the effects of warm water intrusions on populations of macrozooplankton, namely Salpa spp., Phronima spp., Neomysis americana, and Crangon septemspinosa, on Georges Bank. Salpa spp. and Phronima spp. showed a large degree of horizontal co-occurrence, being found predominantly in Upper Slope/Gulf Stream Water and Georges Bank/Gulf of Maine Water. Abundances of these taxa showed striking interannual variability, and were only abundant on the southern flank and in the Northeast Channel in late spring/early summer of 1995 and 1999, periods during which AVHRR imagery and hydrographic data showed the presence of warm water intrusions. These intrusions seemed to have little effect on the distribution of other macrozooplankton (e.g., N. americana and C. septemspinosa). Warm water intrusions can directly affect Salpa spp. and Phronima spp. populations by advecting them onto Georges Bank, although other, more resident populations, especially those inside the 100 m isobath, seem to be little affected by such intrusions.

    This study presents 2D seismic reflection data, seismic velocity analysis, as well as geochemical and isotopic porewater compositions from Opouawe Bank on New Zealand's Hikurangi subduction margin, providing evidence for essentially pure methane gas seepage. The combination of geochemical information and seismic reflection images is an effective way to investigate the nature of gas migration beneath the seafloor, and to distinguish between water advection and gas ascent. The maximum source depth of the methane that migrates to the seep sites on Opouawe Bank is 1,500-2,100 m below seafloor, generated by low-temperature degradation of organic matter via microbial CO2 reduction. Seismic velocity analysis enabled identifying a zone of gas accumulation underneath the base of gas hydrate stability (BGHS) below the bank. Besides structurally controlled gas migration along conduits, gas migration also takes place along dipping strata across the BGHS. Gas migration on Opouawe Bank is influenced by anticlinal focusing and by several focusing levels within the gas hydrate stability zone.

  11. Malachite green photosensitive plates.

    PubMed

    Solano, C

    1989-08-15

    An experimental study of the behavior of malachite green sensitized plates was carried out. The transmittance variation of the irradiated plates was taken as a parameter. It has been observed that photoreduction in the malachite green plates is present only when ammonium dichromate is added to the plates. The introduction of external electron donors does not improve the photochemical reaction. It has been determined that malachite green molecules form a weak complex with the dichromate molecules and this complex can only be destroyed photochemically. This effect can explain the limited response of the malachite green dichromated plates.

  12. Simulations of cm-wavelength Sunyaev-Zel'dovich galaxy cluster and point source blind sky surveys and predictions for the RT32/OCRA-f and the Hevelius 100-m radio telescope

    2015-02-01

    We investigate the effectiveness of blind surveys for radio sources and galaxy cluster thermal Sunyaev-Zel'dovich effects (TSZEs) using the four-pair, beam-switched OCRA-f radiometer on the 32-m radio telescope in Poland. The predictions are based on mock maps that include the cosmic microwave background, TSZEs from hydrodynamical simulations of large scale structure formation, and unresolved radio sources. We validate the mock maps against observational data, and examine the limitations imposed by simplified physics. We estimate the effects of source clustering towards galaxy clusters from NVSS source counts around Planck-selected cluster candidates, and include appropriate correlations in our mock maps. The study allows us to quantify the effects of halo line-of-sight alignments, source confusion, and telescope angular resolution on the detections of TSZEs. We perform a similar analysis for the planned 100-m Hevelius radio telescope (RTH) equipped with a 49-beam radio camera and operating at frequencies up to 22 GHz.We find that RT32/OCRA-f will be suitable for small-field blind radio source surveys, and will detect 33{sup +17}{sub −11} new radio sources brighter than 0.87 mJy at 30 GHz in a 1 deg{sup 2} field at > 5σ CL during a one-year, non-continuous, observing campaign, taking account of Polish weather conditions. It is unlikely that any galaxy cluster will be detected at 3σ CL in such a survey. A 60-deg{sup 2} survey, with field coverage of 2{sup 2} beams per pixel, at 15 GHz with the RTH, would find <1.5 galaxy clusters per year brighter than 60 μJy (at 3σ CL), and would detect about 3.4 × 10{sup 4} point sources brighter than 1 mJy at 5σ CL, with confusion causing flux density errors ∼< 2% (20%) in 68% (95%) of the detected sources.A primary goal of the planned RTH will be a wide-area (π sr) radio source survey at 15 GHz. This survey will detect nearly 3 × 10{sup 5} radio sources at 5σ CL down to 1.3 mJy, and tens of galaxy clusters

    In the last decade the technical advances in high throughput techniques to analyze DNA, RNA and proteins have had a potential major impact on prevention, diagnosis, prognosis and treatment of many human diseases. Key pieces in this process, mainly thinking about the future, are tumour banks and tumour bank networks. To face these challenges, diverse suitable models and designs can be developed. The current article presents the development of a nationwide design of tumour banks in Spain based on a network of networks, specially focusing on its harmonization efforts mainly regarding technical procedures, ethical requirements, unified quality control policy and unique sample identification. We also describe our most important goals for the next years. This model does not correspond to a central tumour bank, but to a cooperative and coordinated network of national and regional networks. Independently from the network in which it is included, sample collections reside in their original institution, where it can be used for further clinical diagnosis, teaching and research activities of each independent hospital. The herein described 'network of networks' functional model could be useful for other countries and/or international tumour bank activities.

    The existing literatures highlights that the security is the primary factor which determines the adoption of Internet banking technology. The secondary information on Internet banking development in Malaysia shows a very slow growth rate. Hence, this study aims to study the banking customers perception towards security concern and Internet banking adoption through the information collected from 150 sample respondents. The data analysis reveals that the customers have much concern about security and privacy issue in adoption of Internet banking, whether the customers are adopted Internet banking or not. Hence, it infers that to popularize Internet banking system there is a need for improvement in security and privacy issue among the banking customers.

    Green building design is becoming broadly adopted, with one green building standard reporting over 3.5 billion square feet certified to date. By definition, green buildings focus on minimizing impacts to the environment through reductions in energy usage, water usage, and minimizing environmental disturbances from the building site. Also by definition, but perhaps less widely recognized, green buildings aim to improve human health through design of healthy indoor environments. The benefits related to reduced energy and water consumption are well-documented, but the potential human health benefits of green buildings are only recently being investigated. The objective of our review was to examine the state of evidence on green building design as it specifically relates to indoor environmental quality and human health. Overall, the initial scientific evidence indicates better indoor environmental quality in green buildings versus non-green buildings, with direct benefits to human health for occupants of those buildings. A limitation of much of the research to date is the reliance on indirect, lagging and subjective measures of health. To address this, we propose a framework for identifying direct, objective and leading "Health Performance Indicators" for use in future studies of buildings and health.

  6. Success is in the bank

    de Vincent-Humphreys, Rupert

    2008-05-01

    As the nation's central bank, the Bank of England is committed to promoting and maintaining monetary and financial stability. Broadly speaking, this means that it sets the interest rate at a level such that the economy should meet the UK government's 2% inflation target in the medium term, and it analyses the financial system to identify and reduce systemic risks to the country's financial infrastructure. The Bank also performs several other critical functions, including managing the approximately £42bn worth of banknotes in circulation and managing the nation's foreign-currency reserves - a multicurrency fund worth some £23bn. As a physicist, I find that I can make a full contribution to this work.

  7. Dry holes of Georges Bank

    SciTech Connect

    Bailey, D.M.

    1982-11-01

    After winning the controversial Georges Bank debate, five oil companies have found only commercially unprofitable dry holes, which experts predict will become anywhere from marginal to vital in future years. The economic boom that offshore drilling was to bring to New England has not materialized despite rumors that the companies found either oil or gas that they are not yet ready to announce. Bad weather and the high cost of offshore drilling may be more responsible for the removal of drilling rigs from the area, but an industry-wide survey finds that only 2200 of 4800 offshore rigs are currently operating. Debate over Georges Bank focused on possible damage to the fishing industry and the windfall the government will receive if leasing is accelerated. Many expect to see rigs returning to Georges Bank in the spring. (DCK)

  8. Green tea in dermatology.

    PubMed

    Pazyar, Nader; Feily, Amir; Kazerouni, Afshin

    2012-01-01

    The purpose of this brief review is to summarize all in vitro, in vivo, and controlled clinical trials on green tea preparations and their uses in dermatology. An extensive literature search was carried out to identify in vivo and in vitro studies as well as clinical trials. Twenty studies were assessed and the results suggest that oral administration of green tea can be effective in the scavenging of free radicals, cancer prevention, hair loss, and skin aging plus protection against the adverse effects associated with psoralen-UV-A therapy. Topical application of green tea extract should be potentially effective for atopic dermatitis, acne vulgaris, rosacea, androgenetic alopecia, hirsutism, keloids, genital warts, cutaneous leishmaniasis, and candidiosis. There are promising results with the use of green tea for several dermatologic conditions; however, the efficacy of oral and topical green tea has not always been confirmed.

  9. Building the green way.

    PubMed

    Lockwood, Charles

    2006-06-01

    Just five or six years ago, the term "green building" evoked visions of barefoot, tie-dyed, granola-munching denizens. There's been a large shift in perception. Of course, green buildings are still known for conserving natural resources by, for example, minimizing on-site grading, using alternative materials, and recycling construction waste. But people now see the financial advantages as well. Well-designed green buildings yield lower utility costs, greater employee productivity, less absenteeism, and stronger attraction and retention of workers than standard buildings do. Green materials, mechanical systems, and furnishings have become more widely available and considerably less expensive than they used to be-often cheaper than their standard counterparts. So building green is no longer a pricey experiment; just about any company can do it on a standard budget by following the ten rules outlined by the author. Reliable building-rating systems like the U.S. Green Building Council's rigorous Leadership in Energy and Environmental Design (LEED) program have done much to underscore the benefits of green construction. LEED evaluates buildings and awards points in several areas, such as water efficiency and indoor environmental quality. Other rating programs include the UK's BREEAM (Building Research Establishment's Environmental Assessment Method) and Australia's Green Star. Green construction is not simply getting more respect; it is rapidly becoming a necessity as corporations push it fully into the mainstream over the next five to ten years. In fact, the author says, the owners of standard buildings face massive obsolescence. To avoid this problem, they should carry out green renovations. Corporations no longer have an excuse for eschewing environmental and economic sustainability. They have at their disposal tools proven to lower overhead costs, improve productivity, and strengthen the bottom line.

  10. Population and the World Bank.

    PubMed

    Sankaran, S

    1973-12-01

    The World Bank Group regards excessive population growth as the single greatest obstacle to economic and social advance in the underdeveloped world. Since 1969 the Bank and the International Development Agency have provided countries with technical assistance through education, fact-finding, and analysis and given 65.7 million dollars for population projects. These projects, in India, Indonesia, Iran, Jamaica, and Malaysia provide training centers, population education, research, and evaluation as well as actual construction of clinics and mobile units. Because population planning touches sensitive areas of religion, caste, race, morality, and politics, the involved nation's political commitment to plan population growth is critical to the success of any program.

    PubMed

    Hulette, Christine M

    2003-07-01

    Many of us who conduct research based on disorders that uniquely affect the human nervous system are involved directly or indirectly with brain banks. Brain banking is by its very nature a multi-disciplinary endeavor that requires close collaboration with our colleagues in clinical departments and also with the families and patients who are donors of brain tissue. These brain tissues will ultimately be used for many types of basic science investigations. Thus, many brain banks are as unique as the basic research programs that they serve. However, there are some commonalities in the field of brain banking. This paper represents a broad overview of brain banking and the issues that are common to all brain banks. Legal and ethical concerns regarding confidentiality of donor records and donor recruitment procedures, as well as safety precautions for technical staff, tissue banking methods and disbursement will be discussed. Finally, issues surrounding financial support for brain banks will be considered.

    A reflectance pulse oximeter that determines oxygen saturation of hemoglobin using two sources of electromagnetic radiation in the green optical region, which provides the maximum reflectance pulsation spectrum. The use of green light allows placement of an oximetry probe at central body sites (e.g., wrist, thigh, abdomen, forehead, scalp, and back). Preferably, the two green light sources alternately emit light at 560 nm and 577 nm, respectively, which gives the biggest difference in hemoglobin extinction coefficients between deoxyhemoglobin, RHb, and oxyhemoglobin, HbO.sub.2.

  11. Bank Erosion Modulated by Exposed Roots from Riparian Vegetation in Small Gravel-Bed Streams

    NASA Astrophysics Data System (ADS)

    Mendoza, A.; Frias, C. E.; Langendoen, E. J.; Abad, J. D.

    2013-12-01

    Bank erosion is a process present in rivers of all the scales and is a key aspect in the evolution of meandering streams. Its magnitude is significantly controlled by the resistance-to-erosion properties of the floodplain materials, which themselves are modified by the varying presence of riparian vegetation. Earlier studies have stated that the physical science of fluvial geomorphology was flawed because of omitting such processes, because they are difficult to describe physically or statistically. For example, the role of vegetation dynamics in modulating river migration, especially for small rivers where the effect of vegetation on channel morphology may be a more important component when compared to larger river systems such as the Amazon or Mississippi Rivers, is largely unknown. Though earlier studies have researched various aspects concerning the effects of riparian vegetation on bank erosion mechanics, a comprehensive framework that integrates and quantifies fluvial erosion and bank failure processes, near-bank hydrodynamics, soil properties and riparian vegetation characteristics is lacking. The effects of exposed roots and rootwads on the near-bank hydrodynamics and sediment transport processes are still not well understood. Laboratory studies have examined in detail the impact of vegetation located only on the bank toe or stream bed. Moreover, there exist no data that explicitly relates the characteristics of riparian vegetation on the bank top to changes in near-bank hydrodynamics and bank erosion mechanics. Further, there is a need to better understand the processes and their interactions occurring at the different spatial scales: single large root, rootwad, and reach. During 2011, 2012 a field campaign was carried out to study the effects of exposed root systems on flow in Fonner Run and Bates Fork, two tributaries of Tenmile Creek (Green and Washington Counties, Pennsylvania). Data collected consist of annual bathymetry, field velocity profiles

  12. The facies distribution of carbonate sediments on Porcupine bank, northeast Atlantic

    NASA Astrophysics Data System (ADS)

    Scoffin, Terence P.; Bowes, George E.

    1988-11-01

    Porcupine Bank (51-54°N, 12-15°W), approximately 10,000 km 2 in area and 150-500 m deep, is effectively removed from present-day terrigenous sedimentation by the broad Irish Shelf to the east, and deep water to the north, west and south. Water temperatures range from 10° to 14.5°C. Carbonate sediments presently accumulate on the bank, mixing with relict quartz sands and lithic pebbles, cobbles and boulders of glacial origin. Traction current structures are absent but biogenic hollows, pits, mounds and trails are prevalent. The lithofacies have a crudely concentric zonation with pelagic foraminiferal oozes in the deepest waters (> 500 m), passing to foraminiferal (pelagic and benthic) glauconitic quartz sands over the bulk of the bank (500-200 m) where scattered patches of Lophelia pertusa coral branches are found, which in turn pass into a narrow zone associated with the lithic boulder field at the bank crest (< 200 m) which has coarse sands composed of quartz and skeletal fragments of benthic organisms-molluscs, echinoids, bryozoans and serpulids. This facies pattern is closely similar to that on Rockall Bank, 500 km to the north, and supports the construction of a depth-related facies model for modern open-sea temperate carbonate sediments: > 500 m, pelagic foraminiferans; 500-200 m, benthic foraminiferans plus Lophelia coral patches; 200-100 m, bivalve-echinoderm; 100-50 m, bryozoan-bivalve-gastropod-serpulid; <50 m, calcareous red algae-bivalve-gastropod-barnacle.

    This document builds on the discussion notes from September 21, 2006. It provides a summary of the ideas relating to the scenario bank tables and their associated requirements. Two conceptual groupings were identified for the contents requirements of the scenario bank. The first, called ProjectTemplate, shall consist of groups. The second, ProjectArchive, shall consist of groups of . The figure below illustrates the multiplicity of the associations between the different tables, with color coding used to distinguish between current MESA (brown) and USDA (light green) requirements. Scenario bank tables are shown in black with their general contents specified within the box. The metadata associated with each table is expected to include database key information as well as relevant timestamps. Each File is expected to be a file with an arbitrary format.

    The solution to the Green and Ampt infiltration equation is expressible in terms of the Lambert W-1 function. Approximations for Green and Ampt infiltration are thus derivable from approximations for the W-1 function and vice versa. An infinite family of asymptotic expansions to W-1 is presented. Although these expansions do not converge near the branch point of the W function (corresponds to Green-Ampt infiltration with immediate ponding), a method is presented for approximating W-1 that is exact at the branch point and asymptotically, with interpolation between these limits. Some existing and several new simple and compact yet robust approximations applicable to Green-Ampt infiltration and flux are presented, the most accurate of which has a maximum relative error of 5 × 10 -5%. This error is orders of magnitude lower than any existing analytical approximations.
