  1. Chris Christiansen and the Chris Cross

    NASA Astrophysics Data System (ADS)

    Orchiston, Wayne; Mathewson, Don

    2009-03-01

    The Chris Cross was the world's first crossed-grating interferometer, and was the brainchild of orte of Australia's foremost radio astronomers, W.N. (Chris) Christiansen, from the CSIRO's Division of Radiophysics in Sydney. Inspired by the innovative and highly-successful E-W and N-S solar grating arrays that he constructed at Potts Hill (Sydney) in the early 1950s, Christiansen sited the Chris Cross at the Division's Fleurs field station near Sydney, and from 1957 to 1988 it provided two-dimensional maps of solar radio emission at 1423 MHz. In 1960 an 18m parabolic antenna was installed adjacent to the Chris Cross array, and when used with the Chris Cross formed the Southern Hemisphere's first high-resolution compound interferometer. A survey of discrete radio sources was carried out with this radio telescope. The Division of Radiophysics handed the Fleurs field station over to the School of Engineering at the University of Sydney in 1963, and Christiansen and his colleagues from the Department of Electrical Engineering proceeded to develop the Chris Cross into the Fleurs Synthesis Telescope (FST) by adding six stand-alone 13.7m parabolic antennas. The FST was used for detailed studies of large radio galaxies, supernova remnants and emission nebulae. The FST was closed down in 1988, and antennas in the original Chris Cross array quickly began to deteriorate. A number of individual antennas in the central part of the array received a new lease of life in 1991 when they were refurbished by staff and students from the Department of Electrical Engineering at the Universityy of Western Sydney, but this only proved to be a temporary reprieve as even these aerials were bulldozed by the landowner in 2004, bringing to an untimely end one of the world's most remarkable radio telescopes.

  9. Image acquisition planning for the CHRIS sensor onboard PROBA

    NASA Astrophysics Data System (ADS)

    Fletcher, Peter A.

    2004-10-01

    The CHRIS (Compact High Resolution Imaging Spectrometer) instrument was launched onboard the European Space Agency (ESA) PROBA satellite on 22 October 2001. CHRIS can acquire up to 63 bands of hyperspectral data at a ground spatial resolution of 36m. Alternatively, the instrument can be configured to acquire 18 bands of data with a spatial resolution of 17m. PROBA, by virtue of its agile pointing capability, enables CHRIS to acquire five different angle images of the selected site. Two sites can be acquired every 24 hours. The hyperspectral and multi-angle capability of CHRIS makes it an important resource for stydying BRDF phenomena of vegetation. Other applications include coastal and inland waters, wild fires, education and public relations. An effective data acquisition planning procedure has been implemented and since mid-2002 users have been receiving data for analysis. A cloud prediction routine has been adopted that maximises the image acquisition capacity of CHRIS-PROBA. Image acquisition planning is carried out by RSAC Ltd on behalf of ESA and in co-operation with Sira Technology Ltd and Redu, the ESA ground station in Belgium, responsible for CHRIS-PROBA.

  12. Sub pixel location identification using super resolved multilooking CHRIS data

    NASA Astrophysics Data System (ADS)

    Sahithi, V. S.; Agrawal, S.

    2014-11-01

    CHRIS /Proba is a multiviewing hyperspectral sensor that monitors the earth in five different zenith angles +55°, +36°, nadir, -36° and -55° with a spatial resolution of 17 m and within a spectral range of 400-1050 nm in mode 3. These multiviewing images are suitable for constructing a super resolved high resolution image that can reveal the mixed pixel of the hyperspectral image. In the present work, an attempt is made to find the location of various features constituted within the 17m mixed pixel of the CHRIS image using various super resolution reconstruction techniques. Four different super resolution reconstruction techniques namely interpolation, iterative back projection, projection on to convex sets (POCS) and robust super resolution were tried on the -36, nadir and +36 images to construct a super resolved high resolution 5.6 m image. The results of super resolution reconstruction were compared with the scaled nadir image and bicubic convoluted image for comparision of the spatial and spectral property preservance. A support vector machine classification of the best super resolved high resolution image was performed to analyse the location of the sub pixel features. Validation of the obtained results was performed using the spectral unmixing fraction images and the 5.6 m classified LISS IV image.

  2. A comparison of superresolution reconstruction methods for multi-angle CHRIS/Proba images

    NASA Astrophysics Data System (ADS)

    Chan, Jonathan Cheung-Wai; Ma, Jianglin; Canters, Frank

    2008-10-01

    Compact High Resolution Imaging Spectrometer onboard the Project for On-board Autonomy, or CHRIS/Proba, represents a new generation of satellite images that provide different acquisitions of the same scene at five different angles. Given the hyperspectral-oriented waveband configuration of the CHRIS images, the scope of its application would be much wider if the present 17m nadir resolution could be refined. This paper presents the results of three superresolution methods applied to multiangular CHRIS/Proba data. The CHRIS images were preprocessed and then calibrated into reflectance using the method described in [1][2]. Automatic registration using an intensity variation approach described in [3] was implemented for motion estimation. Three methods, namely non-uniform interpolation and de-convolution [4], iterative back-projection [5], and total variation [6] are examined. Quantitative measures including peak signal to noise ratio [7], structural similarity [8], and edge stability [9], are used for the evaluation of the image quality. To further examine the benefit of multi-frame superresolution methods, a single-frame superresolution method of bicubic resampling was also applied. Our results show that a high resolution image derived from superresolution methods enhance spatial resolution and provides substantially more image details. The spectral profiles of selected land covers before and after the application of superresolution show negligible differences, hinting the use of superresolution algorithm would not degrade the capability of the data set for classification. Among the three methods, total variation gives the best performance in all quantitative measures. Visual inspections find good results with total variation and iterative back-projection approaches. The use of superresolution algorithms, however, is complex as there are many parameters. In this paper, most of the parameter settings were tuned manually or decided empirically.

  3. Effect of the aerosol type uncertainty on the surface reflectance retrieval using CHRIS/PROBA hyperspectral images over land.

    2014-12-01

    The surface reflectance is crucial for the quantitative analysis of land surface properties in geological, agricultural and urban studies. The first requirement for a reliable surface reflectance estimation is an accurate atmospheric correction obtained by an appropriate selection of aerosol loading and type. The aerosol optical thickness at 550nm is widely used to describe the aerosol loading. Recent works have highlighted the relevant role of the aerosol types on the atmospheric correction process defined by their micro-physical properties. The aim of this work is to evaluate the radiative impact of the aerosol type on the surface reflectance obtained from CHRIS (Compact High Resolution Imaging Spectrometer) hyperspectral data over land. CHRIS on PROBA satellite is an high resolution multi-angular imaging spectrometer, operating in the visible near-infrared spectral domain (400 to 1000 nm). As test case the urban site of Brussels has been selected. The physically-based algorithm CHRIS@CRI (CHRIS Atmospherically Corrected Reflectance Imagery) has been developed specifically for CHRIS data by using the vector version of 6S (6SV) radiative transfer model. The atmospheric data needed for the atmospheric correction were obtained from CIMEL CE-318 of the Brussels AERONET station. CHRIS images were selected if simultaneous AERONET data were available. Other specific requirements for imagery acquisition were high aerosol loading and high solar irradiation. The aerosol radiative impact has been investigated comparing the reflectance obtained by applying the CHRIS@CRI algorithm with different aerosol types: the three aerosol standard of 6SV and two characterized by specific microphysical properties provided by the AERONET station and calculated with FlexAOD code (a post-processing tool of the chemical transport model GEOS-Chem), respectively. The results show a clear dependence of the atmospheric correction results on the aerosol absorption properties.

    Measurements of spectro-directional radiances done with the imaging spectrometer CHRIS on-board the agile platform PROBA are being used to determine key properties of terrestrial vegetation at the appropriate spatial resolution. These data on vegetation properties can then be used to improve the accuracy and the parameterizations of models describing biosphere processes, i.e. photosynthesis and water use by irrigated crops and trees. The vegetation properties considered are: albedo, Leaf Area Index (LAI), fractional cover, fraction of absorbed photosynthetically active radiation (fAPAR) and canopy chlorophyll content. The Natural Park of San Rossore (Pisa, Central Italy) is a primary test site for several national and international research projects dealing with forest ecosystem monitoring. In particular, since 1999 measurements of transpiration and ecosystem gas-exchange have been regularly taken in the park pine forest to characterize its main water and carbon fluxes. In the same period, several aerial flights have been carried out with onboard hyper-spectral sensors (MIVIS, VIRS, AISA), while a series of satellite images have been acquired using both conventional (NOAAAVHRR, Landsat-TM/ETM+) and advanced sensors (CHRIS-PROBA). The final objective of these activities is to calibrate and validate methodologies which integrate remotely sensed and ancillary data for monitoring forest ecosystem. More specifically, a major research effort has been focused on evaluating the additional information content provided by advanced hyper-spectral multi-angular sensors about the main parameters needed for forest characterization (species, LAI, pigment content, etc.). These activities are part of projects which are financed by the Italian and European Space Agencies (ASI and ESA, respectively) within the framework of the CHRIS-PROBA and SPECTRA missions. During 2002 and 2003 nine complete multi-angular acquisitions were successfully performed over the San Rossore site. This

    The Cooperative Health Research In South Tyrol (CHRIS) study is a population-based study with a longitudinal lookout to investigate the genetic and molecular basis of age-related common chronic conditions and their interaction with life style and environment in the general population. All adults of the middle and upper Vinschgau/Val Venosta are invited, while 10,000 participants are anticipated by mid-2017. Family participation is encouraged for complete pedigree reconstruction and disease inheritance mapping. After a pilot study on the compliance with a paperless assessment mode, computer-assisted interviews have been implemented to screen for conditions of the cardiovascular, endocrine, metabolic, genitourinary, nervous, behavioral, and cognitive system. Fat intake, cardiac health, and tremor are assessed instrumentally. Nutrient intake, physical activity, and life-course smoking are measured semi-quantitatively. Participants are phenotyped for 73 blood and urine parameters and 60 aliquots per participant are biobanked (cryo-preserved urine, DNA, and whole and fractionated blood). Through liquid-chromatography mass-spectrometry analysis, metabolite profiling of the mitochondrial function is assessed. Samples are genotyped on 1 million variants with the Illumina HumanOmniExpressExome array and the first data release including 4570 fully phenotyped and genotyped samples is now available for analysis. Participants' follow-up is foreseen 6 years after the first visit. The target population is characterized by long-term social stability and homogeneous environment which should both favor the identification of enriched genetic variants. The CHRIS cohort is a valuable resource to assess the contribution of genomics, metabolomics, and environmental factors to human health and disease. It is awaited that this will result in the identification of novel molecular targets for disease prevention and treatment. PMID:26541195

    This paper discusses the application of Information Management Systems (IMS) for documenting and monitoring World Heritage (WH) properties. The application of IMS in WH can support all stakeholders involved in conservation, and management of cultural heritage by more easily inventorying, mining and exchanging information from multiple sources based on international standards. Moreover, IMS could assist in detecting damages and preparing management strategies to mitigate risks, and slowing down the deterioration of the integrity of WH properties. The case study of the Silk Roads Cultural Heritage Resource Information System (CHRIS), a Belgian Federal Science Policy Office funded project, illustrates the capabilities of IMS in the context of the nomination of the Central Asian Silk Roads on the WH List. This multi-lingual, web-based IMS will act as a collaborative platform allowing for the completion of improved transnational nomination dossiers and subsequent monitoring activities with all necessary baseline information to easily verify consistency and quality of the proposal. The Silk Roads CHRIS Geospatial Content Management System uses open source technologies and allows to georeference data from different scales and sources including data from field recording methods and combine it with historical and heritage features documented through various means such as textual descriptions, documents, photographs, 3D models or videos. Moreover, tailored maps can also be generated by overlaying a selection of available layers and then be exported to support the nomination dossier. Finally, by using this innovative information and decision support system, the State Parties and other interested stakeholders will have access to a complete nomination dossier and could therefore respond more effectively to hazards and disaster phenomena.

  8. Estimating forest species abundance through linear unmixing of CHRIS/PROBA imagery

    2016-09-01

    The advancing technology of hyperspectral remote sensing offers the opportunity of accurate land cover characterization of complex natural environments. In this study, a linear spectral unmixing algorithm that incorporates a novel hierarchical Bayesian approach (BI-ICE) was applied on two spatially and temporally adjacent CHRIS/PROBA images over a forest in North Pindos National Park (Epirus, Greece). The scope is to investigate the potential of this algorithm to discriminate two different forest species (i.e. beech - Fagus sylvatica, pine - Pinus nigra) and produce accurate species-specific abundance maps. The unmixing results were evaluated in uniformly distributed plots across the test site using measured fractions of each species derived by very high resolution aerial orthophotos. Landsat-8 images were also used to produce a conventional discrete-type classification map of the test site. This map was used to define the exact borders of the test site and compare the thematic information of the two mapping approaches (discrete vs abundance mapping). The required ground truth information, regarding training and validation of the applied mapping methodologies, was collected during a field campaign across the study site. Abundance estimates reached very good overall accuracy (R2 = 0.98, RMSE = 0.06). The most significant source of error in our results was due to the shadowing effects that were very intense in some areas of the test site due to the low solar elevation during CHRIS acquisitions. It is also demonstrated that the two mapping approaches are in accordance across pure and dense forest areas, but the conventional classification map fails to describe the natural spatial gradients of each species and the actual species mixture across the test site. Overall, the BI-ICE algorithm presented increased potential to unmix challenging objects with high spectral similarity, such as different vegetation species, under real and not optimum acquisition conditions.

    Insects' infestations of coniferous forests have been in the focus of the forestry community for decades. Research that is dealing with the assessment of the impacts on forests and assessment of the area affected by the infestations has been assisted by remotely sensed data after the onset of civilian remote sensing era and making the large archives of satellite data centres of NASA, ESA, and JAXA available to the researcher's community. The present study assesses the impact from European Bark beetle (Ips typhographus L.) outbreak on Norway Spruce (Picea abies L.) forests in the UNESCO MAB reserve Bistrishko Branishte in Bulgaria using the ESA's third-party mission multiangular satellite CHRIS/PROBA Mode 1 spectroradiometer data. The study aims at assessing the impact of the infestation by comparing the pre- and post-fire CHRIS/PROBA Mode 1 narrow-band vegetation indices (VIs). In order to achieve the study objective the ‘dead spruce forest' areas were extracted using eight target detection algorithms. Statistics from the CHRIS/PROBA Mode 1 VIs was drawn and compared with one another for the two dates of acquisition. It was found that the areas affected by pest infestation can be well differentiated on CHRIS/PROBA data but the results vary due to the date of acquisition, illumination conditions, and season changes. The results from the study suggest that continuous space monitoring of insect infested coniferous forests can be successfully carried out by employing present-day available hyperspectral satellite data.

    Dating abuse is a prevalent adolescent health problem with substantial public health consequences. As many as 1 in 10 high school students in the United States reports being "hit, slapped, or physically hurt on purpose" by his or her boyfriend or girlfriend in the past year. The authors used the Rihanna-Chris Brown dating abuse incident of 2009 as a case study to conduct what is, to our knowledge, the first assessment of media framing of dating abuse. The authors reviewed the 20 leading U.S. single-copy sales magazines published from February to April 2009 and identified 48 relevant articles, which were all printed in 7 tabloid magazines. The authors conducted a content analysis of the media frames of the articles using 5 frame categories: (a) abuse is objectionable, (b) victim-blaming, (c) abuse is sexualized/romanticized, (d) myths about abuse perpetration, and (e) abuse is normalized. Abuse is objectionable was the dominant frame of 40% of articles, victim-blaming in 36%. Although the majority of articles reviewed (83%) made at least passing reference to the idea that abuse is wrong, a minority (40%) used a dominant frame that condemned abuse. Instead, the majority of articles communicated mixed messages about dating abuse, and many minimized the seriousness of partner abuse perpetration. Advocacy is needed to improve future tabloid media framing of dating abuse incidents.

    Hyperspectral remote sensing images are affected by different types of noise. In addition to typical random noise, nonperiodic partially deterministic disturbance patterns generally appear in the data. These patterns, which are intrinsic to the image formation process, are characterized by a high degree of spatial and spectral coherence. We present a new technique that faces the problem of removing the spatially coherent noise known as vertical striping, usually found in images acquired by push-broom sensors. The developed methodology is tested on data acquired by the Compact High Resolution Imaging Spectrometer (CHRIS) onboard the Project for On-board Autonomy (PROBA) orbital platform, which is a typical example of a push-broom instrument exhibiting a relatively high noise component. The proposed correction method is based on the hypothesis that the vertical disturbance presents higher spatial frequencies than the surface radiance. A technique to exclude the contribution of the spatial high frequencies of the surface from the destriping process is introduced. First, the performance of the proposed algorithm is tested on a set of realistic synthetic images with added modeled noise in order to quantify the noise reduction and the noise estimation accuracy. Then, algorithm robustness is tested on more than 350 real CHRIS images from different sites, several acquisition modes (different spatial and spectral resolutions), and covering the full range of possible sensor temperatures. The proposed algorithm is benchmarked against the CHRIS reference algorithm. Results show excellent rejection of the noise pattern with respect to the original CHRIS images, especially improving the removal in those scenes with a natural high contrast. However, some low-frequency components still remain. In addition, the developed correction model captures and corrects the dependency of the noise patterns on sensor temperature, which confirms the robustness of the presented approach. PMID

  14. Evaluation of the Aerosol Type Effect on the Surface Reflectance Retrieval Using Chris/proba Images Over Land

    2015-04-01

    Surface reflectance has a central role in the analysis of land surface for a broad variety of agricultural, geological and urban studies. An accurate atmospheric correction, obtained by an appropriate selection of aerosol type and loading, is the first requirement for a reliable surface reflectance estimation. The aerosol type is defined by its micro-physical properties, while the aerosol loading is described by optical thickness at 550 nm. The aim of this work is to evaluate the radiative impact of the aerosol model on the surface reflectance obtained from CHRIS (Compact High Resolution Imaging Spectrometer) hyperspectral data over land by using the specifically developed algorithm CHRIS@CRI (CHRIS Atmospherically Corrected Reflectance Imagery) based on the 6SV radiative transfer model. Five different aerosol models have been used: one provided by the AERONET inversion products (used as reference), three standard aerosol models in 6SV, and one obtained from the output of the GEOS-Chem global chemistry-transport model (CTM). As test case the urban site of Bruxelles and the suburban area of Rome Tor Vergata have been considered. The results obtained encourages the use of CTM in operational retrieval and provides an evaluation of the role of the aerosol model in the atmospheric correction process, considering the different microphysical properties impact.

  15. Estimation of leaf area index using an angular vegetation index based on in situ measurements and CHRIS/PROBA data

    The Normalized Difference Vegetation Index (NDVI) is widely used for Leaf Area Index (LAI) estimation. It is well documented that the NDVI is extremely subject to the saturation problem when LAI reaches a high value. A new multi-angular vegetation index, the Hotspot-darkspot Difference Vegetation Index (HDVI) is proposed to estimate the high density LAI. The HDVI, defined as the difference between the hot and dark spot NDVI, relative to the dark spot NDVI, was proposed based on the Analytical two-layer Canopy Reflectance Model (ACRM) model outputs. This index is validated using both in situ experimental data in wheat and data from the multi-angular optical Compact High-Resolution Imaging Spectrometer (CHRIS) satellite. Both indices, the Hotspot-Darkspot Index (HDS) and the NDVI were also selected to analyze the relationship with LAI, and were compared with new index HDVI. The results show that HDVI is an appropriate proxy of LAI with higher determination coefficients (R2) for both the data from the in situ experiment (R2=0.7342, RMSE=0.0205) and the CHRIS data (R2=0.7749, RMSE=0.1013). Our results demonstrate that HDVI can make better the occurrence of saturation limits with the information of multi-angular observation, and is more appropriate for estimating LAI than either HDS or NDVI at high LAI values. Although the new index needs further evaluation, it also has the potential under the condition of dense canopies. It provides the effective improvement to the NDVI and other vegetation indices that are based on the red and NIR spectral bands.

  16. Multi-Temporal Monitoring Of Ecological Succession In Tropical Dry Forests Using Angular - Hyperspectral Data (Chris/Proba)

    2015-12-01

    The tropical dry forest is the largest and most threatened ecosystem in Latin America. Remote sensing can effectively contribute to the surveillance of conservation measurements and laws through the monitoring of natural protected areas, at the required temporal and spatial scales. CHRIS/PROBA is the only satellite that presents quasi-simultaneous multi-angular pointing and hyperspectral spectroscopy. These two characteristics permit the study of structural and compositional traces of successional stages within the tropical dry forest. The current study presents the results of mapping the succession of tropical dry forest in the Parque Estadual de la Mata-Seca, in Minas Gerais, Brazil, using a temporal analysis of CHRIS/PROBA images in a time frame of 7 years, between 2008 and 2014. For the purpose the -55° angle of observation has been used, which enhances spectral differences between successional stages. Spectral Angle Mapper has been used for mapping succession of tropical dry forest and afterwards Change Detection Analysis has been performed. Based on our observations, the tropical dry forest in the Parque Estadual de la Mataseca recovers at a fast rate, for the observed period (2008-2014). More than the 50% of the early and intermediate forests has been recovered to a mature forest. Significantly, around a 12% of old pastures have been converted into forest. The spatial analysis also reveals that the areas that recover most rapidly are located in the east of the Park, close to mature forests. The provision of seeds from these forests might be the cause for the fast recovery.

    In this paper we compare two different methodologies for Fractional Vegetation Cover (FVC) retrieval from Compact High Resolution Imaging Spectrometer (CHRIS) data onboard the European Space Agency (ESA) Project for On-Board Autonomy (PROBA) platform. The first methodology is based on empirical approaches using Vegetation Indices (VIs), in particular the Normalized Difference Vegetation Index (NDVI) and the Variable Atmospherically Resistant Index (VARI). The second methodology is based on the Spectral Mixture Analysis (SMA) technique, in which a Linear Spectral Unmixing model has been considered in order to retrieve the abundance of the different constituent materials within pixel elements, called Endmembers (EMs). These EMs were extracted from the image using three different methods: i) manual extraction using a land cover map, ii) Pixel Purity Index (PPI) and iii) Automated Morphological Endmember Extraction (AMEE). The different methodologies for FVC retrieval were applied to one PROBA/CHRIS image acquired over an agricultural area in Spain, and they were calibrated and tested against in situ measurements of FVC estimated with hemispherical photographs. The results obtained from VIs show that VARI correlates better with FVC than NDVI does, with standard errors of estimation of less than 8% in the case of VARI and less than 13% in the case of NDVI when calibrated using the in situ measurements. The results obtained from the SMA-LSU technique show Root Mean Square Errors (RMSE) below 12% when EMs are extracted from the AMEE method and around 9% when extracted from the PPI method. A RMSE value below 9% was obtained for manual extraction of EMs using a land cover use map.

    The changes in wetlands that occur through natural processes, as well as through industrialization and agricultural activities, are decreasing and even annihilating the living spaces of endemic species. Acigöl (Denizli, Turkey), which is a suitable habitat for flamingos (Phoenicopterus ruber), is a lake that is affected by seasonal anomalies as a result of being shallow. Acigöl, which is fed by precipitation, groundwater and the springs that occur along tectonic faults, has no water output other than evaporation and industrial activities. In addition to natural factors, it is important to determine the changes in the wetlands of Acig6l, where industrial salt is produced, in order to reveal the micro-ecological equilibrium, the relationship between climate and natural life, and regulation of industrial activities. Remote sensing tools are frequently used in determination of changes in wetlands. Changes in coastlines, water level and area covered by water are parameters that can be examined by remote sensing while investigating wetlands. In this study, the water-covered area was examined using remote sensing. Within the scope of this study, CHRIS/Proba Mode 2 (water bandset) hyperspectral satellite images, acquired on 9/17/2011 for the season and on 6/18/2012 - 6/19/2012 forwet season, were used in orderto present the seasonal changes in Acigöl, during one hydrogeological period. The processes of noise reduction, cloud screening, atmospheric correction, geometric correction, and identification of wetlands have been implemented on the CHRIS/Proba images. In determining the water-covered areas, the Normalized Difference Water Index (NDWI) was used. It was determined that W6 (560 nm) and W18 (1015 nm) and W2 (447 nm) and W18 (1015 nm) band combinations were most appropriate to be used in NDWI to demonstrate the water-land separation. Using Proba-NDWI image, it was established that an area of 27.4 km2 was covered with water during dry season, and 61.2 km2 was covered

    We assessed the occurrence of Vibrio pathogens in the final effluents of five wastewater treatment plants (WWTPs) located in Amathole and Chris Hani District Municipalities in South Africa over a 12 months period between September 2012 and August 2013 using standard membrane filtration technique followed by cultivation on thiosulphate citrate-bile salts-sucrose (TCBS) agar. The identities of the presumptive Vibrio isolates were confirmed using polymerase chain reaction (PCR) including delineation into V. parahaemolyticus, V. vulnificus and V. fluvialis pathotypes. The counts of Vibrio spp. varied with months in all the study sites and ranged in the order of 101 and 104 CFU/100mL. Vibrio distribution also showed seasonality with high counts being obtained in autumn and spring (p < 0.05). Prevalence of Vibrio spp. among the five WWTPs also differed significantly (p < 0.05). Of the 300 isolates that were confirmed as belonging to the Vibrio genus, 29% (86) were V. fluvialis, 28% (84) were V. vulnificus and 12% (35) were V. parahaemolyticus. The isolation of Vibrio pathogens from the final effluent suggests that this pathogen is in circulation in some pockets of the population and that the WWTPs under study do not efficiently remove bacterial pathogens from the wastewater and consequently are threats to public health.

    Gerlich, Gerhard; Tscheuschner, Ralf D.

    It is shown that the notorious claim by Halpern et al. recently repeated in their comment that the method, logic, and conclusions of our "Falsification Of The CO2 Greenhouse Effects Within The Frame Of Physics" would be in error has no foundation. Since Halpern et al. communicate our arguments incorrectly, their comment is scientifically vacuous. In particular, it is not true that we are "trying to apply the Clausius statement of the Second Law of Thermodynamics to only one side of a heat transfer process rather than the entire process" and that we are "systematically ignoring most non-radiative heat flows applicable to Earth's surface and atmosphere". Rather, our falsification paper discusses the violation of fundamental physical and mathematical principles in 14 examples of common pseudo-derivations of fictitious greenhouse effects that are all based on simplistic pictures of radiative transfer and their obscure relation to thermodynamics, including but not limited to those descriptions (a) that define a "Perpetuum Mobile Of The 2nd Kind", (b) that rely on incorrectly calculated averages of global temperatures, (c) that refer to incorrectly normalized spectra of electromagnetic radiation. Halpern et al. completely missed an exceptional chance to formulate a scientifically well-founded antithesis. They do not even define a greenhouse effect that they wish to defend. We take the opportunity to clarify some misunderstandings, which are communicated in the current discussion on the non-measurable, i.e., physically non-existing influence of the trace gas CO2 on the climates of the Earth.

  1. Unanswered prayers: religiosity and the god-serving bias.

    PubMed

    Riggio, Heidi R; Uhalt, Joshua; Matthies, Brigitte K

    2014-01-01

    Two self-report experiments examined how religiosity affects attributions made for a target person's death. Online adults (Study 1, N = 427) and undergraduate students (Study 2, N = 326) read about Chris who had a heart attack, used religious or health behaviors, and lived or died. Participants made attributions to Chris and God (both studies), and reported their emotions (Study 2). Participants made more attributions to Chris when he lived than when he died, but only when he used health behaviors. The highly religious made more attributions to God, but not when Chris used religious behaviors and died (the God-serving bias); they reported the most positive emotions when Chris lived after using religious behaviors (the Hallelujah effect). Directions for future research in terms of implicit religious beliefs and normative evaluations of religion are discussed. PMID:25280166

  12. Flow Kills Conductivity of Single Wall Carbon Nanotubes (SWNT) Composites

    NASA Astrophysics Data System (ADS)

    Bhatt, Sanjiv; Macosko, Christopher

    2006-03-01

    Most composites of polymer and single wall carbon nanotubes (SWNT) reported in the literature are made by solvent casting or simple compression molding. Commercial utility of these composites requires use of precision injection molding. We have observed a unique behavior wherein the SWNT composites made by injection molding or by extrusion are insulators but upon heating become electrically conductive. This behavior appears to be the result of a relaxation phenomenon in the SWNT composite. During flow into an injection mold or through an extrusion die the well-dispersed SWNT in the polymer matrix tend to align such that they are not in contact with each other and are farther than the minimum required distance, 5 nm (1), to achieve electrical percolation through electron hopping. Upon heating the SWNT relax and either touch each other or are at a distance less than or equal to 5 nm from each other to create a percolating.

  13. Genetic analysis and molecular mapping of crown rust resistance in common wheat.

    Niu, Zhixia; Puri, Krishna D; Chao, Shiaoman; Jin, Yue; Sun, Yongliang; Steffenson, Brian J; Maan, Shivcharan S; Xu, Steven S; Zhong, Shaobin

    2014-03-01

    This is the first report on genetic analysis and genome mapping of major dominant genes for near non-host resistance to barley crown rust ( Puccinia coronata var. hordei ) in common wheat. Barley crown rust, caused by Puccinia coronata var. hordei, primarily occurs on barley (Hordeum vulgare L.) in the Great Plain regions of the United States. However, a few genotypes of common wheat (Triticum aestivum L.) were susceptible to this pathogen among 750 wheat accessions evaluated. To investigate the genetics of crown rust resistance in wheat, a susceptible winter wheat accession PI 350005 was used in crosses with two resistant wheat varieties, Chinese Spring and Chris. Analysis of F1 plants and F2 populations from these two crosses indicated that crown rust resistance is controlled by one and two dominant genes in Chris and Chinese Spring, respectively. To determine the chromosome location of the resistance gene Cr1 in Chris, a set of 21 monosomic lines derived from Chris was used as female parents to cross with a susceptible spring type selection (SSTS35) derived from the PI 350005/Chris cross. Monosomic analysis indicated that Cr1 is located on chromosome 5D in Chris and one of the crown rust resistance genes is located on chromosome 2D in Chinese Spring. The other gene in Chinese Spring is not on 5D and thus is different from Cr1. Molecular linkage analysis and QTL mapping using a population of 136 doubled haploid lines derived from Chris/PI 350005 further positioned Cr1 between SSR markers Xwmc41-2 and Xgdm63 located on the long arm of chromosome 5D. Our study suggests that near non-host resistance to crown rust in these different common wheat genotypes is simply inherited.

  16. Macrophage polarization phenotype regulates adiponectin receptor expression and adiponectin anti-inflammatory response

    van Stijn, Caroline M. W.; Kim, Jason; Lusis, Aldons J.; Barish, Grant D.; Tangirala, Rajendra K.

    Adiponectin (APN), a pleiotropic adipokine that exerts anti-inflammatory, antidiabetic, and antiatherogenic effects through its receptors (AdipoRs), AdipoR1 and AdipoR2, is an important therapeutic target. Factors regulating AdipoR expression in monocyte/macrophages are poorly understood, and the significance of polarized macrophage activation in controlling AdipoR expression and the APN-mediated inflammatory response has not been investigated. The aim of this study was to investigate whether the macrophage polarization phenotype controls the AdipoR expression and APN-mediated inflammatory response. With the use of mouse bone marrow and peritoneal macrophages, we demonstrate that classical activation (M1) of macrophages suppressed (40–60% of control) AdipoR expression, whereas alternative activation (M2) preserved it. Remarkably, the macrophage polarization phenotypes produced contrasting inflammatory responses to APN (EC50 5 µg/ml). In M1 macrophages, APN induced proinflammatory cytokines, TNF-α, IL-6, and IL-12 (>10-fold of control) and AdipoR levels. In contrast, in M2 macrophages, APN induced the anti-inflammatory cytokine IL-10 without altering AdipoR expression. Furthermore, M1 macrophages adapt to a cytokine environment by reversing AdipoR expression. APN induced AdipoR mRNA and protein expression by up-regulating liver X receptor-α (LXRα) in macrophages. These results provide the first evidence that macrophage polarization is a key determinant regulating AdipoR expression and differential APN-mediated macrophage inflammatory responses, which can profoundly influence their pathogenic role in inflammatory and metabolic disorders.—van Stijn, C.

    The group of authors would like to make the following clarification: the retrievals of self-broadened temperature dependence coefficients were performed by the authors both using the multispectrum fit program from Ref. [14] and using the multispectrum fit program of D. Chris Benner [Benner DC, Rinsland CP, Devi VM, Smith MAH, Atkins D. A multispectrum nonlinear least-squares fitting technique. J. Quant. Spectrosc. Radiat. Transf. 1995;53:705-21.). To retrieve the room temperature self-broadening parameters, the authors have used the values in Ref. [4]. For reasons of consistency with the results published for air-broadening and air-shift temperature dependence coefficients in A. Predoi-Cross, A.R.W. McKellar, D. Chris Benner, V. Malathy Devi, R.R. Gamache, C.E. Miller, R.A. Toth, L.R.

    2014-11-01

    Numerous normalized difference spectral indices (NDSIs) derived from leaf measurements and CHRIS/PROBA hyperspectral and multi-angular satellite images were examined for their capacity to track seasonal variations of leaf (εleaf) and canopy (εcan) light use efficiency of a Mediterranean phryganic ecosystem. A series of seasonal field ecophysiological measurements, i.e. leaf area index (LAI), leaf photosynthesis and leaf reflectance, were conducted on the Phlomis fruticosa shrubs at the days of CHRIS acquisitions over the study site. Leaf scale analysis confirmed background theory on the relationship of the photochemical reflectance index (PRI) with εleaf and provided a detailed view of the wavelengths that can be used in PRI formulation for the specific species. In canopy scale analysis, PRI and some alternative formulations of this index based on CHRIS bands, presented the most significant relationships with εcan, indicating that this index preserves its efficiency in satellite observations for the specific ecosystem. Additionally, spectral indices related to chlorophyll and water content were found to present good relationships with εcan. Taking into account the functional relationship between εcan and chlorophyll content, a combination of the xanthophyll de-epoxidation band (531 nm) with 701 nm CHRIS band in a NDSI is suggested as an alternative to the original PRI formulation that could improve seasonal εcan estimations. The satellite observation geometry effects on the determination of εcan were not very intense for the studied ecosystem. However, the most effective viewing direction was proved to be the backward scattering, while zenith observations were the least efficient for the specific ecosystem, most probably due to increased background effects. Even though the sensitivity of the original PRI formulation to εcan was reduced in forward scattering viewing directions, when 531 nm xanthophyll de-epoxidation band was replaced with higher wavelength

    Tragedy of major proportion befell the family of Chris Scarfe and the University of Alberta, Canada, at 8 a.m. on July 20, 1988, when an errant car killed Chris instantly while he was out jogging on his way to work.Born in England, Chris graduated at the University of Durham, beginning his career in experimental petrology with Peter Wyllie at the University of Chicago. Returning to England, he completed a Ph.D. at the University of Leeds, assisting in the development of a high-pressure laboratory with Peter Harris. Appointed at the Univeristy of Alberta in 1972, he steadily developed a new facility, expanding the Department of Geology's embryonic high-pressure laboratory with equipment capable of pressures to 40 kbar and 2000°C. He also supervised research on basalts in the Atlantic Ocean, British Columbia, and the Northwest Territories. He spent 1987-1980 in the Geophysical Laboratory, where he met Eiichi Takahashi, establishing a friendship and a most fruitful working partnership. Quickly realizing t h e significance of very high-pressure equipment, Chris strenuously fought for a major equipment grant from the Natural Sciences and Engineering Research Council of Canada and secured it in time to have a Superpress delivered in February 1988, also utilizing support from the University. Quickly assembling a team of researchers, he brought the Superpress into immediate operation, producing diamonds within a month of start-up. Major discoveries concerning the range of stability of carbonates and on the petrogenesis of komatiites are well under way at pressures up to 200 kbar.

    Serial transnational World Heritage nominations are challenging the way cultural heritage has been managed and evaluated in the past. Serial transnational World Heritage nominations are unique in that they consist of multiple sites listed as one property, distributed in different countries, involving a large diversity of stakeholders in the process. As a result, there is a need for precise baseline information for monitoring, reporting and decision making. This type of nomination requires different methodologies and tools to improve the monitoring cycle from the beginning of the nomination towards the periodic reporting. The case study of the Silk Roads Cultural Heritage Resource Information System (CHRIS) illustrates the use of a Geographical Content Management System (Geo-CMS) supporting the serial transnational World Heritage nomination and the monitoring of the Silk Roads in the five Central Asian countries. The Silk Roads CHRIS is an initiative supported by UNESCO World Heritage Centre (WHC) and the Belgian Federal Science Policy Office (BELSPO), and developed by a consortium headed by the Raymond Lemaire International Centre for Conservation (RLICC) at the KULeuven. The Silk Roads CHRIS has been successfully assisting in the preparation of the nomination dossiers of the Republics of Kazakhstan, Tajikistan and Uzbekistan and will be used as a tool for monitoring tool in the Central Asian countries.

    CASE PRESENTATION At age 8, “Chris,” a Caucasian boy, experienced intermittent auditory and visual hallucinations, but without bizarre behaviors or much deterioration in functioning. At age 15, he developed a depressed mood, started talking to himself, and became socially withdrawn, and his academic performance declined. He was hospitalized and diagnosed as having major depressive disorder with psychotic features. MRI and EEG showed no abnormalities. Treatment with escitalopram (10 mg/day) and aripiprazole (5 mg/day) had little effect. Several weeks after discharge, he was admitted for a second time with the same diagnosis; a third admission, again with the same diagnosis, occurred several months after that. At age 16, Chris developed visual and auditory hallucinations with homicidal ideations. He cut himself superficially following the command of voice hallucinations, and he was hospitalized again, with the diagnosis changed to schizophrenia, paranoid type. During this inpatient stay, he was treated with venlafaxine (150 mg/day) and risperidone (1.5 mg/day). During the same admission, a blood test showed the presence of antinuclear antibodies (ANAs), but the patient had no symptoms of any autoimmune disease. In the meantime, he was also receiving clindamycin/benzoyl peroxide and adapaline gels and minocycline for acne and fluticasone nasal spray and albuterol for asthma. An allergy to gluten was demonstrated by an assay (Accessa Labs) that showed only IgE antigluten antibodies. Chris’sparents reported that he developed anallergy to peanuts and soy at about the same time. Gluten was removed from his diet at the suggestion of the mother, a licensed dietitian. After the dietary change, the intensity of Chris’s auditory hallucinations declined dramatically and the violent element diminished, and he was discharged after 9 weeks. During the next 2 years, Chris remained on a gluten-free diet, which he and his family associated with the disappearance of his

    I cannot agree with Chris Jeynes's assertion (October pp15-16) that to equate religious belief with belief in the tooth fairy is to be unaware of our cultural history. It is true, ofcourse, that cathedrals are inspiring achievements of architecture, but that has no bearing whatsoever on the truth of the beliefs of their designers. There are similarly impressive Muslim holy buildings, motivated by similar beliefs, but, to take one example, Jesus was either the son of God or he was not, so the beliefs of at least one group must therefore be incorrect. Pretty buildings make for poor evidence of universal truths.

    In 1948, an accomplished industrial physicist who had harboured a long-term ambition to become an astronomer joined the newly-formed Radio Astronomy Group in the CSIR's Division of Radiophysics in Sydney, Australia. Thus, W.N. (`Chris') Christiansen (1913-2007) began a new career in the fledgling field of radio astronomy. This paper reviews Christiansen's contribution to both instrumentation development and scientific research during the first phase of his career in radio astronomy, covering his work at the Potts Hill and Fleurs field stations prior to his resignation from the Division of Radiophysics in 1960.

Single-channel openings occurred in "bursts" separated by long closures. A single burst was characterized by the presence of two open conductance levels of equal size and the gating (i.e., openings and closings) during a burst could be almost perfectly described as a superposition of two identical and independent conductances that switched between open and closed states with voltage-dependent rates α and β (Hanke and Miller, 1983) (Fig. 8.1).

Although the 2004 "Long Tail" article in Wired magazine was primarily about the media and entertainment industries, it has since been applied (and perhaps misapplied) to other markets. Analysts describe a "Tail of BPM" market that is, perhaps, several times larger than the traditional BPMS product market. This paper will draw comparisons between the concepts in Anderson's article (and subsequent book) and the BPM solutions market.

    This methodology assesses the accuracy with which remote data characterizes a surface, as a function of Full Width at Half Maximum (FWHM). The purpose is to identify the best remote data that improves the characterization of a surface, evaluating the number of bands in the spectral range. The first step creates an accurate dataset of remote simulated data, using in situ hyperspectral reflectances. The second step evaluates the capability of remote simulated data to characterize this surface. The spectral similarity measurements, which are obtained using classifiers, provide this capability. The third step examines the precision of this capability. The assumption is that in situ hyperspectral reflectances are considered the “real” reflectances. They are resized with the same spectral range of the remote data. The spectral similarity measurements which are obtained from “real” resized reflectances, are considered “real” measurements. Therefore, the quantity and magnitude of “errors” (i.e., differences between spectral similarity measurements obtained from “real” resized reflectances and from remote data) provide the accuracy as a function of FWHM. This methodology was applied to evaluate the accuracy with which CHRIS-mode1, CHRIS-mode2, Landsat5-TM, MIVIS and PRISMA data characterize three coastal waters. Their mean values of uncertainty are 1.59%, 3.79%, 7.75%, 3.15% and 1.18%, respectively. PMID:24434875

    Chris Macaraeg has been a lead scientist for method development, validation, and study support intended for regulated pre-clinical/clinical studies within the Pharmacokinetics and Drug Metabolism department at Amgen Inc, Thousand Oaks, CA. He joined Amgen in 2006. His expertise also includes automation and method transfer to CROs. Chris received his BS degree in Physiological Science and Neuroscience from the University of California, Los Angeles, CA and MS in Forensic Science from Pace University, New York, NY. Stability of therapeutic proteins in biological matrix is an important parameter to evaluate in bioanalytical support of regulated nonclinical or clinical studies. Despite industry guidance publications, many questions still arise as to how these practices are implemented to establish therapeutic protein stability in bioanalytical method validations. This article presents findings from long-term, bench-top and freeze-thaw stability assessments for three therapeutic monoclonal antibodies using either ELISA or electrochemiluminescent technology. Studies illustrate the principles and challenges in stability tests which represent scenarios that samples will likely encounter during sample analysis. Thoughtful consideration of each study requirements and a fit-for-purpose approach is essential in successful establishment of the sample stability parameters in method validation.

    Remote sensing has been used from the 1980s to study inland water quality. However, it was not until the beginning of the twenty-first century that CHRIS (an experimental multi-angle sensor with good spectral and spatial resolutions) and MERIS (with good temporal and spectral resolutions) started to acquire imagery with very good resolutions, which allowed to develop a reliable imagery acquisition system so as to consider remote sensing as an inland water management tool. This paper presents the methodology developed, from the field data acquisition with which to build a freshwater spectral library and the study of different atmospheric correction systems for CHRIS mode 2 and MERIS images, to the development of algorithms to determine chlorophyll-a and phycocyanin concentrations and bloom sites. All these algorithms allow determining water eutrophic and ecological states, apart from generating surveillance maps of toxic cyanobacteria with the main objective of Assessment of the Water Quality as it was used for Monitoring Ecological Water Quality in smallest Mediterranean Reservoirs integrated in the Intercalibration Exercise of European Union Water Framework Directive (WFD). We keep on using it to monitor the Ecological Quality Ratio (EQR) in Spain inland water.

    In his article, Urban special education policy and the lived experience of stigma in a high school science classroom, Chris Hale persuasively argues that the Individuals with Disabilities Education Act and subsequent special education policies have largely failed to serve special education students who are stigmatized by their deficit classification. Though classified students may be doubly stigmatized, research suggests that students of color who live in economically stressed communities are also subject to systemic educational policies that produce stigma; special education should be understood within the larger context of educational policy in the inner city. Though we cannot immediately dismantle the macro level structures that nurture stigma, I suggest pedagogies based on facilitating phenomenological awareness enacted through individual-collectively based methodologies to challenge the stigma that classified as well as non-classified students in the inner city often carry with them.

    For centuries, historians have puzzled over a series of 213 symbols carved into the stone of Scotland’s Rosslyn Chapel. (Disclaimer: You may recognize this chapel from The Da Vinci Code, but this is real and unrelated!) Several years ago, a composer and science enthusiast noticed that the symbols bore a striking similarity to Chladni patterns, the elegant images that form on a two- dimensional surface when it vibrates at certain frequencies. This man’s theory: A 500-year-old melody was inscribed in the chapel using the language of physics. But not everyone is convinced. Slate senior editor Chris Wilson travelled to Scotland to investigate the claims and listen to this mysterious melody, whatever it is. Come find out what he discovered, including images of the patterns and audio of the music they inspired.

    This article describes a unique, self-initiated scheme for the installation of a new boiler at Chorley and District Hospital fueled by waste. The system described is applicable to smaller sites and, since it answers many of the traditional incineration/heat recovery problems, the principle employed is relevant for all sizes of plant. Several Regional Health Authorities have already visited the site and shown a high degree of interest in this pilot project, Terry Finch, the Works Officer, previously worked for Preston Health Authority. He won the Institute of Hospital Engineering's Energy Conservation Competition in 1980. Chris Lowe has worked in hospitals in Chorley for over twelve years and has contributed to many innovative projects throughout that time. PMID:10278901

    November Economic Diversity column for the Tri-City Herald - Topic: Social Purpose Corporations - Excerpt below: On March 31, Governor Chris Gregoire made history when she signed HB2239 and created Washington’s first alternative for-profit corporate structure, the social purpose corporation, or SPC. The new structure allows for-profit entities to formally strive toward creation of social and environmental good as their top corporate priority. This significantly contrasts with the expectation that traditional companies must put creation of shareholder value first. It signals that Washington State believes corporate leadership should have the flexibility and legal backing to make decisions based on the company’s impact on all of its stakeholders rather than on the ability to maximize profits.

  10. Earthquake Simulator Finds Tremor Triggers

    2015-03-27

    Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher has found that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided. The research provides insight into how earthquakes may be triggered and how they recur. Los Alamos researcher Paul Johnson and colleague Chris Marone at Penn State have discovered how wave energy can be stored in certain types of granular materials-like the type found along certain fault lines across the globe-and how this stored energy can suddenly be released as an earthquake when hit by relatively small seismic waves far beyond the traditional “aftershock zone” of a main quake. Perhaps most surprising, researchers have found that the release of energy can occur minutes, hours, or even days after the sound waves pass; the cause of the delay remains a tantalizing mystery.

    Given a social network, who is the best person to introduce you to, say, Chris Ferguson, the poker champion? Or, given a network of people and skills, who is the best person to help you learn about, say, wavelets? The goal is to find a small group of 'gateways': persons who are close enough to us, as well as close enough to the target (person, or skill) or, in other words, are crucial in connecting us to the target. The main contributions are the following: (a) we show how to formulate this problem precisely; (b) we show that it is sub-modular and thus it can be solved near-optimally; (c) we give fast, scalable algorithms to find such gateways. Experiments on real data sets validate the effectiveness and efficiency of the proposed methods, achieving up to 6,000,000x speedup.

    2015-03-01

    The density functional plus dynamical mean field method is outlined and a few recent successes including applications to spin crossover molecules, oxide superlattices and metal-insulator transitions in bulk transition metals are outlined. Insights from the method into the essential role played by lattice distortions (both rotations and bond length changes) in determining the phase diagrams of correlated materials are presented. The key theoretical issue of the double counting correction is outlined, different approaches are compared, and a connection to the energy level differences between strongly and weakly correlated orbitals is presented. Charge transfer across oxide interfaces shown to depend crucially on the double counting correction, suggesting that experiments on oxide superlattices may provide insights into this important problem. Future directions are discussed. This work is performed in collaboration with Jia Chen, Hung Dang, Hyowon Park and Chris Marianetti.

    Recent publications have shown the viability of both detecting a lognormally-distributed signal for water vapor mixing ratio and the improved quality of satellite retrievals in a 1DVAR mixed lognormal-Gaussian assimilation scheme over a Gaussian-only system. This mixed scheme is incorporated into the Gridpoint Statistical Interpolation (GSI) assimilation scheme with the goal of improving forecasts from the Weather Research and Forecasting (WRF) Model in a cycled system. Results are presented of the impact of treating water vapor as a lognormal random variable. Included in the analysis are: 1) the evolution of Tropical Storm Chris from 2006, and 2) an analysis of a "Pineapple Express" water vapor event from 2005 where a lognormal signal has been previously detected.

    Thank you, Chris and Subir, for nominating me for the Fleming Medal and for your very kind comments on my research. In looking back over the medalists since 1962, it is hard to believe that I could be lucky enough to join such distinguished company. Yet, I have been very lucky through life. First, I was lucky to go to Christ's Hospital and Cambridge University. Second, my Aunt Marjorie married a physicist, Johnnie Clegg, who was an excellent teacher and inspiration for me. Third, to be born in England in the mid-1930s was to be a member of a fortunate generation of scientists. Providing one safely negotiated World War II, one joined the academic world at a time of great excitement, of expansion, and support for science.

    1999-01-01

    Pressure broadening and pressure-induced shift coefficients due to water and nitrogen have been determined for water vapor transitions in the CO2 region of interest to Project HALOE. The temperature dependences of the widths and shifts have also been determined for selected transitions in this region. Results have been compared with values available in the literature. The line parameters have been obtained from the analysis of room temperature recordings of the spectrum of pure water and recordings of the spectra of heated water/nitrogen mixtures. The recordings of the water vapor spectrum were obtained with Fourier Transform Spectrometers at Kitt Peak and at the Justus-Liebig-Universitat Giessen. Up to eighteen spectra have been fitted simultaneously with a multispectrum nonlinear least-squares fitting technique developed by Dr. D. Chris Benner and colleagues.

    SLOPOS-12 included: Positron Interactions with Surfaces Positron Beam and Detector Technology Positron Interactions with Atoms and Molecules Positronium Science Defects and Vacancies in Materials Porosity and Open Volume in Materials Antimatter in Biomedical Science Anti-hydrogen Studies Positron Transport Annihilation On a sad note, delegates paid tribute to the contributions of one of our colleagues, Chris Beling, who tragically passed away shortly before the meeting. Chris' contributions to positron science and to the education of young scientists were noted in a number of the invited presentations. It is an honour for our community to begin these proceedings with a short tribute to Chris' life by Professor Paul Coleman. The Workshop could not have occurred without the generous support of our sponsors: The ARC Centre for Antimatter-Matter Studies, The Australian National University, Flinders University, James Cook University, The Institute of Physics (UK) and the Australian Government's Department of Innovation, Industry, Science and Research. It would also not have been possible without the hard work of the Local and International Organising Committees and the friendly and efficient staff at the All Seasons Resort, Magnetic Island. We are most grateful for the on-site assistance of Gillian Drew, the CAMS student and postdoc team, the financial wizardry of Chris Kalos, and the post-Workshop editorial assistance of Julia Wee and Adam Edwards. Finally we would like to thank all of the attendees at SLOPOS12 for their scientific contributions to the Workshop, and for the warm spirit of engagement which characterised the scientific discussions and social occasions. SLOPOS13 will be held in Germany in 2013 and we all look forward to the occasion.

    It was proposed to continue with development and application in the two active-passive areas of Active Tuned Vibration Absorbers (ATVA) and smart foam applied to the reduction of interior noise in aircraft. In general the work was focused on making both techniques more efficient, practical and robust thus increasing their application potential. The work was also concerned with demonstrating the potential of these two technologies under realistic implementations as well as understanding the fundamental physics of the systems. The proposed work consisted of a three-year program and was tightly coordinated with related work being carried out in the Structural Acoustics Branch at NASA LaRC. The work was supervised and coordinated through all phases by Prof Chris Fuller of Va Tech.

  13. Emerging narrative forms of knowledge representation in the health sciences: two texts in a postmodern context.

    PubMed

    Abma, Tineke A

    2002-01-01

    Qualitative health researchers have recently begun to experiment with narrative forms of knowledge representation, often incorporating postmodern theory and related constructivist epistemology. However, misunderstanding of these ideas may lead to rejection of, or lack of interest in, these unconventional texts, which in turn might impede the use of narrative forms in the health sciences. The author's aim is to "open up" the provocative domain of ideas about knowledge representation and explain how the forms operate. Two texts are described with respect to narrative plotting, author's stance, character building, voices, and rhetorical tropes: Troubling the Angels, Patti Lather and Chris Smithies's account of support groups for women living with HIV/AIDS, and The Social Meaning of Surgery, Nicolas Fox's description and sociological analysis of daily life in the operating theater. Other examples of emerging forms are integrated and made relevant to the substantive texts chosen for analysis.

    High-resolution, high signal-to-noise spectra of mono-substituted 13C-ethane (13C12CH_6) in the 12.2 μm region were recorded with a Bruker IFS 125HR Fourier transform spectrometer. The spectra were obtained for four sample pressures at three different temperatures between 130 and 208 K using a 99% 13C-enriched ethane sample contained in a 20.38-cm long coolable absorption cell. A multispectrum nonlinear least squares fitting technique was used to fit the same intervals in the four spectra simultaneously to determine line positions and intensities. Similar to our previous analyses of 12C_2H_6 spectra in this same region, constraints were applied to accurately fit each pair of doublet components arising from torsional Coriolis interaction of the excited ν12 = 1 state with the nearby torsional ν_6 = 3 state. Line intensities corresponding to each spectrum temperature (130 K, 178 K and 208 K) are reported for 1660 ν12 absorption lines for which the assignments are known, and integrated intensities are estimated as the summation of the measured values. The measured line positions and intensities (re-scaled to 296 K) are compared with values in recent editions of spectroscopic databases. K. Sung, A. W. Mantz, L. R. Brown, et al., J. Mol.

    A standard for measuring metadata quality in spectral libraries Barbara Rasaiah, Simon Jones, Chris Bellman RMIT University Melbourne, Australia barbara.rasaiah@rmit.edu.au, simon.jones@rmit.edu.au, chris.bellman@rmit.edu.au ABSTRACT There is an urgent need within the international remote sensing community to establish a metadata standard for field spectroscopy that ensures high quality, interoperable metadata sets that can be archived and shared efficiently within Earth observation data sharing systems. Metadata are an important component in the cataloguing and analysis of in situ spectroscopy datasets because of their central role in identifying and quantifying the quality and reliability of spectral data and the products derived from them. This paper presents approaches to measuring metadata completeness and quality in spectral libraries to determine reliability, interoperability, and re-useability of a dataset. Explored are quality parameters that meet the unique requirements of in situ spectroscopy datasets, across many campaigns. Examined are the challenges presented by ensuring that data creators, owners, and data users ensure a high level of data integrity throughout the lifecycle of a dataset. Issues such as field measurement methods, instrument calibration, and data representativeness are investigated. The proposed metadata standard incorporates expert recommendations that include metadata protocols critical to all campaigns, and those that are restricted to campaigns for specific target measurements. The implication of semantics and syntax for a robust and flexible metadata standard are also considered. Approaches towards an operational and logistically viable implementation of a quality standard are discussed. This paper also proposes a way forward for adapting and enhancing current geospatial metadata standards to the unique requirements of field spectroscopy metadata quality.

  18. Estimating Light Use Efficiency Of A Pine And Beech Forest From Leaf To Ecosystem Scale Using The Photochemical Reflectance Index

    The prospect of accurately tracking photosynthetic processes using satellite observations is very important for understanding and monitoring global carbon cycle and climate change. The present study investigates the efficiency of the Photochemical Reflectance Index (PRI) in detecting light use efficiency (ɛ) in different spatial scales. The study sites concern two dense and homogenous forests in the region of Epirus (Greece), one evergreen coniferous forest dominated by Pinus nigra species and one deciduous forest dominated by Fagus sylvatica. Field and laboratory measurements of canopy structure (Leaf Area Index - LAI, needle and shoot structure characteristics), leaf pigment concentrations, leaf photosynthesis and water potential were performed throughout the growth period. These measurements were used for an accurate description of the ecophysiological characteristics of the two species and thus the parameterization of a Canopy Photosynthesis Model in order to estimate canopy photosynthesis. During the same period, leaf and canopy reflectance measurements were performed in the field to test and evaluate PRI regarding it's efficiency to track ɛ in leaf and canopy scale. In order to investigate the potential application of PRI for estimating ɛ in a broader spatial scale, satellite hyperspectral or superspectral sensors can be used. Compact High Resolution Imaging Spectrometer (CHRIS) and Moderate Resolution Imaging Spectroradiometer (MODIS) are currently available for this purpose and their performances were tested within the present study. An agreement between the fluctuations of CHRIS PRI and the field measured canopy PRI has been found, with both of them appearing to track the ɛ fluctuation efficiently. However, MODIS PRI shows no intense fluctuation and no relationship with ɛ and field measured PRI, probably due to lack of atmospheric correction and the effects of viewing and illumination geometry.

    The spectral region near 4850 Cm-1 is used to monitor atmospheric carbon dioxide, but current accuracies of the line intensities and line shape coefficients do not permit carbon dioxide mixing ratios to be obtained to 1 ppm (about one part in 400). To improve the line parameters, we are remeasuring the prominent CO2 bands in this region specifically to characterize the non-Voigt effects of line mixing and speed dependence at room temperature. The laboratory spectra of air- and self-broadened CO2 have been recorded at a variety of pressures, path lengths, mixing ratios and resolutions (0.005 to 0.01 Cm-1) with two different Fourier transform spectrometers (the McMath-Pierce FTS at Kitt Peak and a Bruker 125 HR FTS at JPL). The line parameters of some 2000 transitions are being derived by simultaneous multispectrum fitting using a few dozen spectra encompassing a 230 Cm-1 wide spectral interval. The rovibrational constants for line positions and the band intensities and Herman-Wallis coefficients are being retrieved directly from the spectra, rather than floating positions and intensities individually. Self and foreign Lorentz widths and pressure shifts are being determined for the stronger bands while non-Voigt coefficients describing line mixing and speed dependence are being obtained for at least one of the strongest bands.

    All of the work conducted under the auspices of DE-FC02-01ER25473 was characterized by exceptionally close collaboration with researchers at the Lawrence Berkeley National Laboratory (LBNL). This included having one of my graduate students - Sarah Williams - spend the summer working with Dr. Ann Almgren a staff scientist in the Center for Computational Sciences and Engineering (CCSE) which is a part of the National Energy Research Supercomputer Center (NERSC) at LBNL. As a result of this visit Sarah decided to work on a problem suggested by Dr. John Bell the head of CCSE for her PhD thesis, which she finished in June 2007. Writing a PhD thesis while working at one of the University of California (UC) managed DOE laboratories is a long established tradition at the University of California and I have always encouraged my students to consider doing this. For example, in 2000 one of my graduate students - Matthew Williams - finished his PhD thesis while working with Dr. Douglas Kothe at the Los Alamos National Laboratory (LANL). Matt is now a staff scientist in the Diagnostic Applications Group in the Applied Physics Division at LANL. Another one of my graduate students - Christopher Algieri - who was partially supported with funds from DE-FC02-01ER25473 wrote am MS Thesis that analyzed and extended work published by Dr. Phil Colella and his colleagues in 1998. Dr. Colella is the head of the Applied Numerical Algorithms Group (ANAG) in the National Energy Research Supercomputer Center at LBNL and is the lead PI for the APDEC ISIC which was comprised of several National Laboratory research groups and at least five University PI's at five different universities. Chris Algieri is now employed as a staff member in Dr. Bill Collins' research group at LBNL developing computational models for climate change research. Bill Collins was recently hired at LBNL to start and be the Head of the Climate Science Department in the Earth Sciences Division at LBNL. Prior to this he had

    Papakyritsis, Ioannis

    The field of motor speech disorders in Greek is substantially underresearched. Additionally, acoustic studies on lexical stress in dysarthria are generally very rare (Kim et al. 2010). This dissertation examined the acoustic and perceptual effects of Greek dysarthria focusing on lexical stress. Additional possibly deviant speech characteristics were acoustically analyzed. Data from three dysarthric participants and matched controls was analyzed using a case study design. The analysis of lexical stress was based on data drawn from a single word repetition task that included pairs of disyllabic words differentiated by stress location. This data was acoustically analyzed in terms of the use of the acoustic cues for Greek stress. The ability of the dysarthric participants to signal stress in single words was further assessed in a stress identification task carried out by 14 naive Greek listeners. Overall, the acoustic and perceptual data indicated that, although all three dysarthric speakers presented with some difficulty in the patterning of stressed and unstressed syllables, each had different underlying problems that gave rise to quite distinct patterns of deviant speech characteristics. The atypical use of lexical stress cues in Anna's data obscured the prominence relations of stressed and unstressed syllables to the extent that the position of lexical stress was usually not perceptually transparent. Chris and Maria on the other hand, did not have marked difficulties signaling lexical stress location, although listeners were not 100% successful in the stress identification task. For the most part, Chris' atypical phonation patterns and Maria's very slow rate of speech did not interfere with lexical stress signaling. The acoustic analysis of the lexical stress cues was generally in agreement with the participants' performance in the stress identification task. Interestingly, in all three dysarthric participants, but more so in Anna, targets stressed on the 1st

  6. Reminiscences regarding Professor R.N. Christiansen

    Swarup, Govind

    2008-11-01

    In this short paper I describe my initiation into the field of radio astronomy fifty years ago, under the guidance of Professor W.N. ('Chris') Christiansen, soon after I joined the C.S.I.R.O.'s Division of Radiophysics (RP) in Sydney, Australia, in 1953 under a 2-year Colombo Plan Fellowship. During the early 1950s Christiansen had developed a remarkable 21 cm interferometric grating array of 32 east-west aligned parabolic dishes and another array of 16 dishes in a north-south direction at Potts Hill. Christiansen and Warburton used these two arrays to scan the Sun strip-wise yielding radio brightness distribution at various position angles. During a three month period I assisted them in making a 2-dimensional map of the Sun by a complex Fourier transform process. In the second year of my Fellowship, Parthasarathy and I converted the 32-antenna east-west grating array to study solar radio emission at 60cm. During this work, I noticed that the procedure adopted by Christiansen for phase adjustment of the grating array was time consuming. Based on this experience, I later developed an innovative technique at Stanford in 1959 for phase adjustment of long transmission lines and paths in space. In a bid to improve on the method used by Christiansen to make a 2-dimensional map of the Sun from strip scans, I suggested to R.N. Bracewell in 1962 a revolutionary method for direct 2-dimensional imaging without Fourier transforms. Bracewell and Riddle developed the method for making a 2-dimensional map of the Moon using strip scans obtained with the 32 element interferometer at Stanford. The method has since revolutionized medical tomography. I describe these developments here to highlight my initial work with Christiansen and to show how new ideas often are developed by necessity and have their origin in prior experience! The 32 Potts Hill solar grating array dishes were eventually donated by the C.S.I.R.0. to India and were set up by me at Kalyan near Mumbai, forming the

  7. Gravity Probe B Number 4 Gyro Inspected

    NASA Technical Reports Server (NTRS)

    2000-01-01

    The Gravity Probe B (GP-B) is the relativity experiment developed at Stanford University to test two extraordinary predictions of Albert Einstein's general theory of relativity. The experiment will measure, very precisely, the expected tiny changes in the direction of the spin axes of four gyroscopes contained in an Earth-orbiting satellite at a 400-mile altitude. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are very slightly warped by the presence of the Earth, and, more profoundly, how the Earth's rotation very slightly drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe. In this photograph, Stanford engineer, Chris Gray, is inspecting the number 4 gyro under monochromatic light. GP-B is among the most thoroughly researched programs ever undertaken by NASA. This is the story of a scientific quest in which physicists and engineers have collaborated closely over many years. Inspired by their quest, they have invented a whole range of technologies that are already enlivening other branches of science and engineering. Launched April 20, 2004 , the GP-B program was managed for NASA by the Marshall Space Flight Center. Development of the GP-B is the responsibility of Stanford University along with major subcontractor Lockheed Martin Corporation. (Image credit to Russ Leese, Stanford University.)

    This 2007 symposium of the Canadian Association of University Surgeons brought together surgeons from a number of jurisdictions to discuss the challenges and opportunities that reduced physician work hours will bring to the care of the surgical patient. Dr. Brian Taylor, president of the association, underscored the need to find a balance between the benefits of diminished workloads/work hours and the loss of continuity of care. He opined that Canada needs to learn from our European colleagues' experience. Dr. Per-Olof Nyström, professor of surgery, presented the modern Swedish model of surgical care, which had to be developed as a consequence of the European Union's legal restrictions on the amount of time an individual surgeon may work. Sweden employs a team-based shared-care model driven by the individual surgeon's expertise rather than the "village factory" model of the multiskilled, multitasking approach of surgical care more prevalent in Canada. Dr. Chris de Gara, secretary treasurer of the association, presented the evidence base for (and against) work-hour restrictions and how well-designed systems can ensure effective continuity of care. Dr. Stewart Hamilton illustrated how one such system for the delivery of the emergency general surgical services has evolved at the University of Alberta Hospital, which demonstrated its effectiveness in providing quality surgical continuity of care. Dr. Debrah Wirtzfeld underscored the importance of trainee lifestyle and how modern Web-based technologies can ensure reduced errors with the implementation of a "sign-out" system.

  14. Period Evolution of Double White Dwarf Binaries Under the Influence of Gravitational Wave Emissions

    2016-03-01

    Compact objects, such as Double White Dwarf (DWD) binaries, are the most populous producers of gravitational waves (GW) at low frequencies. The gravitational radiation (GR) emitted from the Galactic DWD binary population will create an unresolvable signal known as the confusion noise-limit (CNL) in the space-based evolved Laser Interferometer Space Antenna (eLISA). It is predicted that many thousand DWD binary signals will rise above the CNL and create resolvable GW signals. In previous work, Heather Johnson, from the University of Texas-Austin, produced ~61 million DWD systems using the binary population features in the StarTrack population synthesis code created by Chris Belczynski. We have created an evolutionary code that continues the period evolution of the DWD binaries under the effects of GR. Our present model only accounts for detached binary systems, but we are working on incorporating more features. Current period evolution models often extrapolate data based on smaller binary populations, however our model will utilize ~61 million binary systems in order to avoid inaccuracies.We then use two standard cylindrical density distributions to populate a galaxy with the evolved systems. We also discuss correlations between the progenitor binaries and the eLISA sources.

    Line parameter errors can contribute significantly to the total errors in retrievals of terrestrial atmospheric ozone concentration profiles using the strong 9.6-μm band, particularly for nadir-viewing experiments Detailed knowledge of the interfering ozone signal is also needed for retrievals of other atmospheric species in this spectral region. We have determined Lorentz air-broadening and pressure-induced shift coefficients along with their temperature dependences for a number of transitions in the ν_3 fundamental band of 16O_3. These results were obtained by applying the multispectrum nonlinear least-squares fitting technique to a set of 31 high-resolution infrared absorption spectra of O_3 recorded at temperatures between 160 and 300 K with several different room-temperature and coolable sample cells at the McMath-Pierce Fourier transform spectrometer at the National Solar Observatory on Kitt Peak. We compare our results with other available measurements and with the ozone line parameters in the HITRAN database. J.~Worden et al., J.~Geophys.~Res. 109 (2004) 9308-9319.

    This article examines the possibility of exploiting ground reflectance in the near-infrared (NIR) for monitoring grassland phytomass on a temporal basis. Three new spectral vegetation indices (infrared slope index, ISI; normalized infrared difference index, NIDI; and normalized difference structural index, NDSI), which are based on the reflectance values in the H25 (863–881 nm) and the H18 (745–751 nm) Chris Proba (mode 5) bands, are proposed. Ground measurements of hyperspectral reflectance and phytomass were made at six grassland sites in the Italian and Austrian mountains using a hand-held spectroradiometer. At full canopy cover, strong saturation was observed for many traditional vegetation indices (normalized difference vegetation index (NDVI), modified simple ratio (MSR), enhanced vegetation index (EVI), enhanced vegetation index 2 (EVI 2), renormalized difference vegetation index (RDVI), wide dynamic range vegetation index (WDRVI)). Conversely, ISI and NDSI were linearly related to grassland phytomass with negligible inter-annual variability. The relationships between both ISI and NDSI and phytomass were however site specific. The WinSail model indicated that this was mostly due to grassland species composition and background reflectance. Further studies are needed to confirm the usefulness of these indices (e.g. using multispectral specific sensors) for monitoring vegetation structural biophysical variables in other ecosystem types and to test these relationships with aircraft and satellite sensors data. For grassland ecosystems, we conclude that ISI and NDSI hold great promise for non-destructively monitoring the temporal variability of grassland phytomass. PMID:24347746

    2014-12-01

    In 2013, Liberal MP Chris Spence introduced a Private Member's Bill to the New South Wales Parliament, reinvigorating an earlier Bill introduced by Christian Democrat MP Fred Nile. If passed, the Bill would have bestowed legal personhood on fetuses of 20 weeks or more for the purpose of grievous bodily harm offences in the Crimes Act 1900 (NSW). The Bill had the potential to undermine freedom of choice for women in relation to abortions prior to the point of viability (capacity for fetal existence outside the womb) as well as other decisions concerning pregnancy and childbirth. One hypothesis is that legislative measures such as this that support the rights of the fetus are well intentioned initiatives by those for whom the fetus is an essentially independent entity or symbol of innocence and moral purity whose existence must be protected over and above the interests and independent decision-making capacity of the mother. This column explores this hypothesis in the context of the paradoxical negative commercial implications of such legislation on multiple areas involving fetal-maternal interaction including surrogacy.

    Structural colors create iridescent colors in bird feathers. The goal is to understand why structural colors act the way they do in certain situations. The research conducted over the course of the fall semester was to understand the optical phenomenon producing colors in individual barbules. Through the use of a polarizing optical microscope, certain hypotheses were built to explain certain phenomenon. Using a dark field illumination involving light acting at wide angles in microscopy, the barbules were not affected by polarization. So it can be suggested that the barbules have certain characteristics, possibly internal, which prevents wide-angle polarization. More recently, it was found that the barbules, when stacked upon one another, create a discoloration at the cross over point. It can be suggested that the barbules act as thin films and create a situation of thin film interference. More data will be taken using the Scanning Electron Microscope as well as getting cross sectional data to help understand the internal characteristics of the barbules.

    The highly successful Mission STS-74 comes to a smooth conclusion as the orbiter Atlantis returns to Kennedy Space Center. Atlantis touched down on Runway 33 of the Shuttle Landing Facility at 12:01:27 p.m. EST, November 20. The final Space Shuttle flight of 1995 marked the second docking of the U.S. Space Shuttle to the Russian Space Station Mir. To simplify the remaining five Shuttle-Mir docking currently scheduled, the five astronauts on Atlantis attached a Russian-built Docking Module to Mir during the eight-day mission. Two solar arrays were stowed on the module, which will serve as a permanent extension to the Kristall docking port on the station. Atlantis' crew and the three cosmonauts on Mir also transferred materials to and from the station. Leading the STS-74 crew is Commander Kenneth D. Cameron; James D. Halsell Jr. is the pilot; the three mission specialists are Jerry L. Ross, William S. 'Bill' McArthur Jr. and Chris A. Hadfield, who represents the Canadian Space Agency. This was the 27th end-of-mission landing at KSC in Shuttle program history. The Shuttle-Mir dockings are one aspect of Phase 1 activities leading the way toward the international space station; the United States, Russian, Canada, Japan and a group of European nations have joined together to build the orbiting outpost in space later this decade.

    The world is at the dawn of a third industrial revolution, the digital revolution, that brings great changes the world over. Today, computing devices, the Internet, and the World Wide Web are vital technology tools that affect every aspect of everyday life and success. While computing technologies offer enormous benefits, there are equally enormous safety and security risks that have been growing exponentially since they became widely available to the public in 1994. Cybercriminals are increasingly implementing sophisticated and serious hack attacks and breaches upon our nation's government, financial institutions, organizations, communities, and private citizens. There is a great need for computer scientists to carry America's innovation and economic growth forward and for cybersecurity professionals to keep our nation safe from criminal hacking. In this digital age, computer science and cybersecurity are essential foundational ingredients of technological innovation, economic growth, and cybersecurity that span all industries. Yet, America's K-12 education institutions are not teaching the computer science and cybersecurity skills required to produce a technologically-savvy 21st century workforce. Education is the key to preparing students to enter the workforce and, therefore, American K-12 STEM education must be reformed to accommodate the teachings required in the digital age.

The submersible is seen in the water with the Diver Operated Plug (DOP). Kennedy Space Center's solid rocket booster (SRB) retrieval team and ASD laboratory staff hope that the new robotic technology will make the process of inserting the plug safer and less strenuous. Currently, scuba divers manually insert the DOP into the aft nozzle of a jettisoned SRB 60 to 70 feet below the surface of the Atlantic Ocean. After the plug is installed, water is pumped out of the booster allowing it to float horizontally. It is then towed back to Hangar AF at Cape Canaveral Air Station for refurbishment. Deep Sea Systems of Falmouth, Mass., built the submersible for NASA.

    In 2013, Liberal MP Chris Spence introduced a Private Member's Bill to the New South Wales Parliament, reinvigorating an earlier Bill introduced by Christian Democrat MP Fred Nile. If passed, the Bill would have bestowed legal personhood on fetuses of 20 weeks or more for the purpose of grievous bodily harm offences in the Crimes Act 1900 (NSW). The Bill had the potential to undermine freedom of choice for women in relation to abortions prior to the point of viability (capacity for fetal existence outside the womb) as well as other decisions concerning pregnancy and childbirth. One hypothesis is that legislative measures such as this that support the rights of the fetus are well intentioned initiatives by those for whom the fetus is an essentially independent entity or symbol of innocence and moral purity whose existence must be protected over and above the interests and independent decision-making capacity of the mother. This column explores this hypothesis in the context of the paradoxical negative commercial implications of such legislation on multiple areas involving fetal-maternal interaction including surrogacy.

  7. The Mexico City Policy: a "gag rule" that violates free speech and democratic values.

    With the support of the Republican leadership of the US House of Representatives, Representative Chris Smith of New Jersey continues to attempt to limit provision of US family planning (FP) funding to foreign nongovernmental organizations (NGOs) who agree to enforce absolute prohibitions on engaging in abortion-related activities. Despite the fact that the House is withholding funds to meet US obligations to the UN and to support the International Monetary Fund, US President Clinton refuses to give in to pressure to enforce what amounts to a "gag rule." The Secretary of State explains that Clinton has no intention of punishing organizations engaging in free-speech protected democratic activities in foreign countries. Smith has offered a self-styled "compromise" that would allow Clinton to waive disqualification for a foreign NGO offering abortion services with its own funds in compliance with the laws of its country. This waiver would penalize the international FP program by $44 million and would not apply to the broad prohibitions against abortion lobbying (including lobbying for changes in laws, sponsoring conferences and workshops on "alleged" defects in abortion laws, and drafting and distributing materials or public statements on "alleged defects"). Smith's emphasis on the "lobbying" ban has widened the issue from a debate on abortion to a debate on democracy and free speech. Opposition to Smith's proposal is, thus, rising in many quarters. Smith also endorses withholding US contributions to the UN Population Fund because the fund has resumed work in China. PMID:12293660

    Most (75%) of the anti-infectives that save countless lives and enormously improve quality of life originate from microbes found in nature. Herein, we described a global visualization of the detectable molecules produced from a single microorganism, which we define as the ‘molecular network’ of that organism, followed by studies to characterize the cellular effects of antibacterial molecules. We demonstrate that Streptomyces roseosporus produces at least four non-ribosomal peptide synthetase-derived molecular families and their gene subnetworks (daptomycin, arylomycin, napsamycin and stenothricin) were identified with different modes of action. A number of previously unreported analogs involving truncation, glycosylation, hydrolysis and biosynthetic intermediates and/or shunt products were also captured and visualized by creation of a map through MS/MS networking. The diversity of antibacterial compounds produced by S. roseosporus highlights the importance of developing new approaches to characterize the molecular capacity of an organism in a more global manner. This allows one to more deeply interrogate the biosynthetic capacities of microorganisms with the goal to streamline the discovery pipeline for biotechnological applications in agriculture and medicine. This is a contribution to a special issue to honor Chris Walsh’s amazing career. PMID:24149839

  9. Comparing accuracy for leaf area index estimation inverting a simple empirical model and a radiative transfer model by using multiangular and hyperspectral data

    The Leaf Area Index is a key parameter that is indispensable for many biophysical and climatic models. LAI is required for modeling crop water requirements for precision farming and agricultural resource management. The objective of this study was to investigate different approaches for estimating LAI from EO data. To this aim multiangular CHRIS/PROBA data, from SPARC 2003 and 2004, were used in the inversion of PROSPECT-SAILH models using a numerical optimization technique based on Marquardt-Levenberg algorithm. The optimal spectral sampling to estimate LAI was investigated using a sensitivity analysis. From the same data set, the reflectance in the red and near-infrared bands, from the closer to nadir image, was considered in order to estimate the LAI using an empirical approach based on the CLAIR model. The LAI obtained from the empirical approach was finally employed as prior information in the physical based model. LAI values retrieved with the combined approaches were realistically estimated with a good accuracy (RMSE is 0.51 m2m-2).

    Leaf Area Index (LAI) is a key parameter for many biophysical and climatic models. In the field of interest of our research group, an accurate LAI estimation is needed for modelling crop water requirements for precision farming and agricultural resource management applications. The objective of this study is to assess the accuracy of LAI retrieval from EO data by means of a radiative transfer model inversion technique. To this aim multi-angular CHRIS/PROBA data, from SPARC 2003 and 2004 campaigns, has been employed in the inversion of PROSPECT-SAILH (P-SH) model by using a numerical optimisation technique based on the Marquardt-Levenberg (M-L) algorithm. From the same data set, the closer to nadir reflectance in the red and near-infrared bands has been selected in order to estimate LAI by using an empirical approach based on the CLAIR model. Such estimated LAI has been thus employed as prior information in the P-SH model. LAI values retrieved with this combined approach have been estimated with good accuracy for some type of crops (e.g. R2 = 0.80, RMSE=0.51 m2m-2 for Alfalfa canopies). Ongoing and future work includes further improvements of the M-L optimisation method and the implementation of a different optimisation method based on Genetic Algorithm GA.

    In this response to Yupanqui Munoz and Charbel El-Hani's paper, "The student with a thousand faces: From the ethics in videogames to becoming a citizen", we examine their critique of videogames in science education. Munoz and El-Hani present a critical analysis of videogames such as Grand Theft Auto, Street Fight, Command and Conquer: Generals, Halo, and Fallout 3 using Neil Postman's (1993) conceptualization of technopoly along with Bill Green and Chris Bigum's (1993) notion of the cyborg curriculum. Our contention is that these games are not representative of current educational videogames about science, which hold the potential to enhance civic scientific literacy across a diverse range of students while promoting cross-cultural understandings of complex scientific concepts and phenomenon. We examine games that have undergone empirical investigation in general education science classrooms, such as River City, Quest Atlantis, Whyville, Resilient Planet, and You Make Me Sick!, and discuss the ways these videogames can engage students and teachers in a constructivist dialogue that enhances science education. Our critique extends Munoz and El-Hani's discussion through an examination of the ways videogames can enhance science education by promoting inclusive education, civic scientific literacy, and global citizenship.

  15. The Multifarious Martian Mantle

    2004-06-01

    Pieces of relatively young lava flows from Mars (all less than 600 million years old) preserve a record of the planet's initial segregation into core, mantle, and crust. Research by Lars Borg (University of New Mexico), his colleague David Draper, and his former colleagues at the Johnson Space Center, Chris Herd (University of Alberta, Canada), and Cyrena Goodrich (formerly at the University of Hawaii and now at Kingsborough Community College in Brooklyn, New York) shows that there are distinctive regions in the interior of Mars. These regions, or reservoirs as cosmochemists like to call them, formed early, about 4.5 billion years ago, and come in two flavors. One, dubbed "enriched," contains high concentrations of trace elements, has a high ratio of lanthanum to ytterbium (La/Yb), high strontium-87 to strontium-86 ratio, a low ratio of neodynmium-143 to neodynmium-144, and is relatively oxidized. The other, dubbed "depleted," contains lower levels of trace elements, has lower La/Yb and strontium-87 to strontium-86, higher neodynmium-143 to neodynmium-144, and is relatively reduced (much less oxidizing than the enriched reservoir). There are mixtures in between these extremes. The reservoirs may have formed in a global magma ocean. Their preservation for 4.5 billion years indicates that Mars, in contrast to Earth, did not have active plate tectonics since the reservoirs formed.

    Lake Champlain has bays undergoing chronic cyanobacterial harmful algal blooms that pose a public health threat. Monitoring and assessment tools need to be developed to support risk decision making and to gain a thorough understanding of bloom scales and intensities. In this research application, Landsat 8 Operational Land Imager (OLI), Rapid Eye, and Proba Compact High Resolution Imaging Spectrometer (CHRIS) images were obtained while a corresponding field campaign collected in situ measurements of water quality. Models including empirical band ratio regressions were applied to map chlorophyll-a and phycocyanin concentrations; all sensors performed well with R2 and root-mean-square error (RMSE) ranging from 0.76 to 0.88 and 0.42 to 1.51, respectively. The outcomes showed spatial patterns across the lake with problematic bays having phycocyanin concentrations >25 µg/L. An alert status metric tuned to the current monitoring protocol was generated using modeled water quality to illustrate how the remote sensing tools can inform a public health monitoring system. Among the sensors utilized in this study, Landsat 8 OLI holds the most promise for providing exposure information across a wide area given the resolutions, systematic observation strategy and free cost.

  17. Transsexuality: some remarks based on clinical experience.

    Hertoft, P; Sørensen, T

    People with severe gender identity problems have always existed. Some hope to find a solution to their deep intrapersonal conflicts in a so-called sex transformation. The term 'transsexual' was coined by Cauldwell in 1949 and since then an unknown number of people all over the world, probably more biological men than women, have undergone a hormonal and surgical sex-transformation procedure. In this chapter we discuss the impossibility of real sex change from man to woman and vice versa. We briefly touch on two classical cases of sex transformation with some connection with Denmark: the Lili Elbe case of 1930 and the famous Chris Jorgensen case from the early fifties. We discuss the incidence of transsexuality and follow-up studies of patients, and give preliminary results from a Danish study of 110 people (81 men and 29 women) who during the past 25 years have applied for a sex-change operation. Of these, 56 individuals (42 men and 14 women) have had such operations. These are minimum figures since some transsexuals are known to have had operations in other countries but have not contacted Danish hospitals or health personnel.

  18. Order and Disorder in Short Block Polymers

    2015-03-01

    Block polymers have captivated the interest of scientists and engineers for more than half a century. The phase behavior of this class of self-assembling soft material is well understood in the limit of infinite molecular weight, based on the self-consistent mean-field theory pioneered by Leibler. At practical molecular sizes, typically around N ~ 1000 repeat units, fluctuation effects become highly significant in the vicinity of the order disorder transition. One-loop corrections to mean-field theory, first described by Brazovski and applied to block polymers by Fredrickson and Helfand, are not expected to be applicable in this limit. Moreover, the drive towards ever smaller domain dimensions, and the opportunity to circumvent transport limitations associated with entanglements, have motivated experiments with yet lower molecular weight block polymers, N less than 100. This presentation will describe the consequences of fluctuations and the equilibrium structural properties of short model AB diblock polymers in the symmetric (f = 1/2) and asymmetric (f --> 0) regimes above and below the order-disorder transition. The consequences of fluctuations and access to equilibrium states will be described in the 1-dimensional stripped (lamellar) phase and the ordering of point particles in 3-dimensions, respectively. As N --> 1 computer simulation with realistic molecular detail becomes feasible presenting exciting opportunities to compliment the associated theoretical challenges.

    The House of Representatives passed a bill, by a two-thirds majority (288-139), prohibiting late (at 19-20 weeks gestation) abortion using intrauterine cranial decompression. The bill now awaits judgment from the Senate Judiciary Committee for hearings. If the bill becomes law, physicians performing the procedure could face up to two years in prison. Chris Smith, Republican cochairman of the House Pro-Life Caucus, who introduced the bill in the House, described the vote as historic. During his emotional speech, the procedure was described in order to desanitize a form of abortion that he called barbaric torture. Patricia Schroeder, Colorado House Representative, argued that the wording of the bill allowed the procedure only when it was the only possible way of saving the mother's life; the woman's health and future fertility were, in effect, set aside. There is no exception clause for when the woman's life or health is endangered. Schroeder fears women will be forced to choose more dangerous methods of abortion and believes more discussion is required regarding health risks and a more precise definition of when the procedure may be used. She is joined by the California Medical Association, the American Medical Women's Association, the American College of Obstetricians and Gynaecologists, and the American Medical Association.

    The oxygen A band is used for numerous atmospheric experiments, but spectral line parameters that sufficiently describe the spectrum to the level required by OCO2 and other high precision/accuracy experiments are lacking. Fourier transform spectra from the Jet Propulsion Laboratory and cavity ring down spectra from the National Institute of Standards and Technology were fitted simultaneously using the William and Mary multispectrum nonlinear least squares fitting technique into a single solution including the entire band. In addition, photoacoustic spectra already available from the California Institute of Technology will be added to the solution. The three types of spectrometers are complementary allowing the strengths of each to fill in the weaknesses of the others. With this technique line positions, intensities, widths, shifts, line mixing, Dicke narrowing, temperature dependences and collision induced absorption have been obtained in a single physically consistent fit.

  6. House battles over UN family planning funds.

    1997-05-01

    The House International Relations Subcommittee on Operations and Human Rights approved HR 1253 by voice vote on April 10, 1997. HR 1253 is a reauthorization of State Department programs for fiscal years 1998 and 1999. Republican anti-choice subcommittee chair Chris Smith inserted language which prohibits the State Department from funding the UNFPA, the UN family planning program. The restriction would only be lifted if President Clinton certifies that the UNFPA has ended all activities in China or that no government-coerced abortions have taken place in China during the previous 12 months. Since neither change is likely, the Smith provision would effectively bar the US from funding the UNFPA, even though the agency does not support abortion services. The State Department authorization was then taken up by the full House International Relations Committee as part of HR 1486, a bill which would reorganize foreign policy operations. By a 23-16 vote on May 6, the committee approved an amendment which deleted the Smith provision and instead stipulated that US funds cannot be used for UNFPA programs in China. Pro-choice representative Tom Campbell sponsored the amendment which deleted the Smith provision. President Clinton's proposed budget for fiscal year 1998 also includes the Campbell provision.

    In terms of cerebellar research and ataxiology, a most fascinating period is currently going on. Numerous academic groups are now focusing their innovative research on the so-called little brain, hidden at the bottom of our brain. Indeed, its unique anatomical features make the cerebellum a wonderful window to address major questions about the central nervous system. The seventh international symposium of the SRC was held in Brussels at the Palace of Academies from May 8 to 10, 2015. The main goal of this dense symposium was to gather in a 2-day meeting senior researchers of exceptional scientific quality and talented junior scientists from all over the world working in the multidisciplinary field of cerebellar research. Fundamental and clinical researchers shared the latest knowledge and developments in this rapidly growing field. New ideas, addressed in a variety of inspiring talks, provoked a vivid debate. Advances in genetics, development, electrophysiology, neuroimaging, neurocognition and affect, as well as in the cerebellar ataxias and the controversies on the roles and functions of the cerebellum were presented. The Ferdinando Rossi lecture and the key-note lecture were delivered by Jan Voogd and Chris De Zeeuw, respectively. Contacts between researchers of different neuroscientific disciplines established a robust basis for novel trends and promising new cooperations between researchers and their centers spread all over the world.

    We use STM-based techniques for measuring the electrical properties of metal|molecule|metal junctions. For a family of molecules HS(CH2)6-Ar-(CH2)6SH (Ar = substituted benzene), we found that the single molecule conductances varied significantly with substituent, being higher for electron-donating substituents [1]. Later, we studied the effect of increasing conjugation on this system by examining oligothiophenes HS(CH2)6-[C4H4S]x-(CH2)6SH (x = 1, 2, 3, 5). We found that the conductances of junctions involving these molecules depended upon the medium in which the measurements were made. In fact, for x = 3, the conductance was two orders of magnitude higher in the presence of water than in anhydrous conditions [2]. This presentation will outline these studies, together with the results of transport calculations that rationalise these unusual findings, and will set the results in the context of existing literature on medium effects in single molecule conductance determinations.

VMS versions through 8.0 are available. Yet now, the advent of powerful, inexpensive microcomputers has made possible "desktop" image processing. Here, a set of software that parallels VICAR routines, and expands upon them, is presented, written for the DOS operating system. PC VICAR was written in Microsoft FORTRAN by Chris Barnet for use on a 386-based microcomputer. Other hardware requirements include a Wieland Systems Design PCIP100A board and a separate video monitor for use as a display device. A CD-ROM drive is a convenient way of accessing raw Voyager images in PDS format. PC VICAR was developed at New Mexico State University. An upgraded version is being tested at the University of Northern Iowa (UNI). This version accepts images in a variety of formats including Voyager, HST, Galileo, and those used with ground-based detectors. The software is user-friendly, and extra effort has been made to make the Voyager image-processing tasks simple and easy to understand. At UNI, we propose to provide other observers with image navigation and measurements of features associated with the collision of comet Shoemaker-Levy and Jupiter in July, 1994. Funding for this project was provided in part by the NASA/University Joint Venture (JOVE) Program.

  10. Unscientific America: What's the Problem? What's the Solution?

    2012-08-01

    It's a staggering paradox. Thee United States has the finest universities in the world and invests more money in scientific research than any other nation. Yet we're allowing ourselves to fall behind in science education, and behind other countries like China, in green energy innovation. Meanwhile, most Americans know very little about science, and often don't even understand what they're missing - or why science matters to their lives. No wonder we have unending battles over the science of global warming, the teaching of evolution, and whether or not to vaccinate our children. How could the U.S. become so...unscientific? And what can we do about it? How can we make science popular again, or even...sexy? In this talk, Chris Mooney explains the reasons for the gap between science and the U.S. public, and what we can do to bring these two worlds - both of which need the other - back together again.

  11. US poised to outlaw late abortion technique.

    Bozalis, D

    1995-11-18

    The House of Representatives passed a bill, by a two-thirds majority (288-139), prohibiting late (at 19-20 weeks gestation) abortion using intrauterine cranial decompression. The bill now awaits judgment from the Senate Judiciary Committee for hearings. If the bill becomes law, physicians performing the procedure could face up to two years in prison. Chris Smith, Republican cochairman of the House Pro-Life Caucus, who introduced the bill in the House, described the vote as historic. During his emotional speech, the procedure was described in order to desanitize a form of abortion that he called barbaric torture. Patricia Schroeder, Colorado House Representative, argued that the wording of the bill allowed the procedure only when it was the only possible way of saving the mother's life; the woman's health and future fertility were, in effect, set aside. There is no exception clause for when the woman's life or health is endangered. Schroeder fears women will be forced to choose more dangerous methods of abortion and believes more discussion is required regarding health risks and a more precise definition of when the procedure may be used. She is joined by the California Medical Association, the American Medical Women's Association, the American College of Obstetricians and Gynaecologists, and the American Medical Association.

    1995-01-01

    The highly successful Mission STS-74 comes to a smooth conclusion as the orbiter Atlantis returns to Kennedy Space Center. Atlantis touched down on Runway 33 of the Shuttle Landing Facility at 12:01:27 p.m. EST, November 20. The final Space Shuttle flight of 1995 marked the second docking of the U.S. Space Shuttle to the Russian Space Station Mir. To simplify the remaining five Shuttle-Mir docking currently scheduled, the five astronauts on Atlantis attached a Russian-built Docking Module to Mir during the eight-day mission. Two solar arrays were stowed on the module, which will serve as a permanent extension to the Kristall docking port on the station. Atlantis' crew and the three cosmonauts on Mir also transferred materials to and from the station. Leading the STS-74 crew is Commander Kenneth D. Cameron; James D. Halsell Jr. is the pilot; the three mission specialists are Jerry L. Ross, William S. 'Bill' McArthur Jr. and Chris A. Hadfield, who represents the Canadian Space Agency. This was the 27th end-of-mission landing at KSC in Shuttle program history. The Shuttle-Mir dockings are one aspect of Phase 1 activities leading the way toward the international space station; the United States, Russian, Canada, Japan and a group of European nations have joined together to build the orbiting outpost in space later this decade.

  13. Genome increase as a clock for the origin and evolution of life

    Sharov, Alexei A

    2006-01-01

    Background The size of non-redundant functional genome can be an indicator of biological complexity of living organisms. Several positive feedback mechanisms including gene cooperation and duplication with subsequent specialization may result in the exponential growth of biological complexity in macro-evolution. Results I propose a hypothesis that biological complexity increased exponentially during evolution. Regression of the logarithm of functional non-redundant genome size versus time of origin in major groups of organisms showed a 7.8-fold increase per 1 billion years, and hence the increase of complexity can be viewed as a clock of macro-evolution. A strong version of the exponential hypothesis is that the rate of complexity increase in early (pre-prokaryotic) evolution of life was at most the same (or even slower) than observed in the evolution of prokaryotes and eukaryotes. Conclusion The increase of functional non-redundant genome size in macro-evolution was consistent with the exponential hypothesis. If the strong exponential hypothesis is true, then the origin of life should be dated 10 billion years ago. Thus, the possibility of panspermia as a source of life on earth should be discussed on equal basis with alternative hypotheses of de-novo life origin. Panspermia may be proven if bacteria similar to terrestrial ones are found on other planets or satellites in the solar system. Reviewers This article was reviewed by Eugene V.

Two microprobes will hitchhike on the Mars Polar Lander, scheduled to be launched Jan. 3, 1999, aboard a Delta II rocket. The solar-powered spacecraft is designed to touch down on the Martian surface near the northern-most boundary of the south pole in order to study the water cycle there. The lander also will help scientists learn more about climate change and current resources on Mars, studying such things as frost, dust, water vapor and condensates in the Martian atmosphere. The Mars microprobes, called Deep Space 2, are part of NASA's New Millennium Program. They will complement the climate-related scientific focus of the lander by demonstrating an advanced, rugged microlaser system for detecting subsurface water. Such data on polar subsurface water, in the form of ice, should help put limits on scientific projections for the global abundance of water on Mars.

  18. Selective conservatism in trauma management: a South African contribution.

    PubMed

    Clarke, D L; Thomson, S R; Madiba, T E; Muckart, D J J

    2005-08-01

    Trauma in South Africa has been termed the malignant epidemic. This heritage was the result of a violent colonial legacy which spawned the apartheid system of injustice and the struggle against it The Apartheid regime created overcrowding, unemployment, social stagnation, and the disruption of normal family life. These were the catalysts for the incredible amount of criminal and interpersonal conflict in South Africa over the last 50 years. African townships such as Soweto in Johannesburg and Umlazi in Durban were crime-ridden ghettoes where the apartheid police were more interested in fueling the "black on black" violence rather than trying to curb it. Baragwanath (Chris Hani-Baragwanath) and King Edward the VIII Hospital in Durban were the "trauma care epicenters" on the fringes of these huge urban conurbations. Both were designated black hospitals and both were underfunded and dilapidated. Even the architecture was similar, with prefabricated, poorly ventilated structures serving as wards and clinics in both institutions. Trauma volumes consisted of between 10 and 20 laparotomies on weekend nights at the height of political unrest. This led to vast individual experience in several areas of trauma typified by Demetriades' experience with 70 penetrating cardiac injuries. In this setting of limited resources and an overwhelming volume of trauma, selective conservatism as a surgical philosophy took root and has profoundly influenced the way the world manages trauma. We detail and illustrate the evolution of this approach and its continued application. PMID:15983718

    The Space Shuttle Atlantis breaks free from its Earthly ties and soars toward the stars. The five astronauts assigned to Mission STS-74 are headed for an historic rendezvous in space: the second docking of the U.S. Space Shuttle with the Russian Space Station Mir. Atlantis lifted off from Launch Pad 39A at 7:30:43.071 a.m. EST, Nov. 12. The mission commander is Kenneth D. Cameron; James D. Halsell Jr. is the pilot, and the three mission specialists are Jerry L. Ross, William S. 'Bill' McArthur Jr., and Chris A. Hadfield, who represents the Canadian Space Agency. The profile of Mission STS-74 represents a direct precursor to the types of activities flight crews will carry out during assembly and operation of the international space station later this decade. During their eight-day spaceflight, the crew will deliver a Russian-built Docking Module to Mir. The Docking Module will be attached to the docking port on Mir's Kristall module to serve as a permanent extension to the station to simplify future linkups with the Shuttle. The Shuttle astronauts and the three cosmonauts on Mir also will transfer logistics materials to and from Mir.

    In this study we have re-analyzed high-resolution spectra of pure CO and CO broadened by hydrogen recorded in the spectral range of the first overtone band. We have used four different line shapes in the multispectrum analysis (Voigt, speed dependent Voigt, Rautian, and Rautian with speed dependence) and compared the resulting line shape parameters. The line mixing coefficients have been calculated using the Exponential Power Gap and the Energy Corrected Sudden scaling laws. A classical approach was applied to calculate CO line widths in CO-H_2 and CO-CO collisions. The formulas of classical impact theory are used for calculation of dipole absorption half-widths along with exact 3D Hamilton equations for simulation of molecular motion. The calculations utilize Monte Carlo averaging over collision parameters and simple interaction potential (Tipping-Herman + electrostatic). Molecules are treated as rigid rotors. The dependences of CO half-widths on rotational quantum number J≤ 24 are computed and compared with measured data at room temperature. V. Malathy Devi et al., J. Mol. Spectrosc. 228 (2004) 580-592.

    After a prolonged absence, the word 'nuclear' has returned to the lexicon of sustainable domestic energy resources. Due in no small part to its demonstrated reliability, nuclear power is poised to playa greater role in the nation's energy future, producing clean, carbon-neutral electricity and contributing even more to our energy security. To nuclear scientists, the resurgence presents an opportunity to inject new technologies into the industry to maximize the benefits that nuclear energy can provide. 'By developing new options for waste management and exploiting new materials to make key technological advances, we can significantly impact the use of nuclear energy in our future energy mix,' says Chris Stanek, a materials scientist at Los Alamos National Laboratory. Stanek approaches the big technology challenges by thinking way small, all the way down to the atoms. He and his colleagues are using cutting edge atomic-scale simulations to address a difficult aspect of nuclear waste -- predicting its behavior far into the future. Their research is part of a broader, coordinated effort on the part of the Laboratory to use its considerable experimental, theoretical, and computational capabilities to explore advanced materials central to not only waste issues, but to nuclear fuels as well.

    Few tools exist for creating and visualizing complex three-dimensional simulation meshes, and these have limitations that restrict their application to particular geometries and circumstances. Mesh generation needs to trend toward ever more general applications. To that end, we have developed MeshVoro, a tool that is based on the Voro++ (Chris H. Rycroft, 2009. Chaos 19, 041111) library and is capable of generating complex three-dimensional Voronoi tessellation-based (unstructured) meshes for the solution of problems of flow and transport in subsurface geologic media that are addressed by the TOUGH (Pruess, K., Oldenburg C., Moridis G., 1999. Report LBNL-43134, 582. Lawrence Berkeley National Laboratory, Berkeley, CA) family of codes. MeshVoro, which includes built-in data visualization routines, is a particularly useful tool because it extends the applicability of the TOUGH family of codes by enabling the scientifically robust and relatively easy discretization of systems with challenging 3D geometries. We describe several applications of MeshVoro. We illustrate the ability of the tool to straightforwardly transform a complex geological grid into a simulation mesh that conforms to the specifications of the TOUGH family of codes. We demonstrate how MeshVoro can describe complex system geometries with a relatively small number of grid blocks, and we construct meshes for geometries that would have been practically intractable with a standard Cartesian grid approach. We also discuss the limitations and appropriate applications of this new technology.

  3. BRISC v.1.0

    2011-01-06

    BRISC is a developmental prototype for a nextgeneration “systems-level” integrated performance and safety code (IPSC) for nuclear reactors. Its development served to demonstrate how a lightweight multi-physics coupling approach can be used to tightly couple the physics models in several different physics codes (written in a variety of languages) into one integrated package for simulating accident scenarios in a liquid sodium cooled “burner” nuclear reactor. For example, the RIO Fluid Flow and Heat transfer codemore » developed at Sandia (SNL: Chris Moen, Dept. 08005) is used in BRISC to model fluid flow and heat transfer, as well as conduction heat transfer in solids. Because BRISC is a prototype, its most practical application is as a foundation or starting point for developing a true production code. The sub-codes and the associated models and correlations currently employed within BRISC were chosen to cover the required application space and demonstrate feasibility, but were not optimized or validated against experimental data within the context of their use in BRISC.« less

    A collaboration initiated in 1989 between Judy Lachvayder and Chris Cullis in response to an application for a Christa McCauliffe Fellowship has grown into a substantial program. A one week course in biotechnology, using the Cold Spring Harbor Vector van, was run in 1990. A similar one week summer course was run by Cullis for high school freshmen and sophomores. Both programs (teachers and students) have continued with support from the Edison Biotechnology Center (EBTC), U.S. Biochemical, the Howard Hughes Medical Institute and CWRU. A core of teachers from these courses were brought together by the EBTC and the Cleveland Regional Area of Biologists (CRABS) was formed. This group holds regular meetings and develops new classroom exercises. A group of master teachers from the participants have also held their own workshops at local and national meetings. A Science and Society Symposium was held in February 1994 and an equipment loan program for teachers has been established. The students who attended the programs are being tracked to determine if they continued their careers in science.

  5. When combinatorial processing results in reconceptualization: toward a new approach of compositionality

    PubMed Central

    Schumacher, Petra B.

    2013-01-01

    Propositional content is often incomplete but comprehenders appear to adjust meaning and add unarticulated meaning constituents effortlessly. This happens at the propositional level (The baby drank the bottle) but also at the phrasal level (the wooden turtle). In two ERP experiments, combinatorial processing was investigated in container/content alternations and adjective-noun combination transforming an animate entity into a physical object. Experiment 1 revealed that container-for-content alternations (The baby drank the bottle) engendered a Late Positivity on the critical expression and on the subsequent segment, while content-for-container alternations (Chris put the beer on the table) did not exert extra costs. In Experiment 2, adjective-noun combinations (the wooden turtle) also evoked a Late Positivity on the critical noun. First, the Late Positivities are taken to reflect discourse updating demands resulting from reference shift from the original denotation to the contextually appropriate interpretation (e.g., the reconceptualization form animal to physical object). This shift is supported by the linguistic unavailability of the original meaning, exemplified by copredication tests. Second, the data reveal that meaning alternations differ qualitatively. Some alternations involve (cost-free) meaning selection, while others engender processing demands associated with reconceptualization. This dissociation thus calls for a new typology of metonymic shifts that centers around the status of the involved discourse referents. PMID:24098293

Chris Algieri is now employed as a staff member in Dr. Bill Collins' Climate Science Department in the Earth Sciences Division at LBNL working with computational models of climate change. Finally, it should be noted that the work conducted by Professor Puckett and his students Sarah Williams and Chris Algieri and described in this final report for DOE grant # DE-FC02-03ER25579 is closely related to work performed by Professor Puckett and his students under the auspices of Professor Puckett's DOE SciDAC grant DE-FC02-01ER25473 An Algorithmic and Software Framework for Applied Partial Differential Equations: A DOE SciDAC Integrated Software Infrastructure Center (ISIC). Dr. Colella was the lead PI for this SciDAC grant, which was comprised of several research groups from DOE national laboratories and five university PI's from five different universities. In theory Professor Puckett tried to use funds from the SciDAC grant to support work directly involved in implementing algorithms developed by members of his research group at UCD as software that might be of use to Puckett's SciDAC CoPIs. (For example, see the work reported in Section 2.2.2 of this final report.) However, since there is considerable lead time spent developing such algorithms before they are ready to become `software' and research plans and goals change as the research progresses, Professor Puckett supported each member of his research group partially with funds from the SciDAC APDEC ISIC DE-FC02-01ER25473 and partially with funds from this DOE MICS grant DE-FC02-03ER25579. This has necessarily resulted in a significant overlap of project areas that were funded by both grants. In particular, both Sarah Williams and Chris Algieri were supported partially with funds from grant # DE-FG02-03ER25579, for which this is the final report, and in part with funds from Professor Puckett's DOE SciDAC grant # DE-FC02-01ER25473.

    2012-01-01

    At its 2009 annual symposium, chaired by Dr. William (Bill) Pollett, the Canadian Association of University Surgeons brought together speakers with expertise in surgery and medical education to discuss the role of surgical simulation for improving surgical training and safety. Dr. Daniel Jones, of Harvard University and the 2009 Charles Tator Lecturer, highlighted how simulation has been used to teach advanced laparoscopic surgery. He also outlined how the American College of Surgeons is moving toward competency assessments as a requirement before surgeons are permitted to perform laparoscopic surgery on patients. Dr. Teodor Grantcharov, from the University of Toronto, highlighted the role of virtual reality simulators in laparoscopic surgery as well as box trainers. Dr. Peter Brindley from the University of Alberta, although a strong proponent of simulation, cautioned against an overzealous adoption without addressing its current limitations. He also emphasized simulation’s value in team training and crisis resource management training. Dr. Chris de Gara, also from the University of Alberta, questioned to what extent simulators should be used to determine competency. He raised concerns that if technical skills are learned in isolation, they may become “decontextualized,” and therefore simulation might become counterproductive. He outlined how oversimplification can have an “enchanting” effect, including a false sense of security. As a result, simulation must be used appropriately and along the entire education continuum. Furthermore, far more needs to be done to realize its role in surgical safety. PMID:22854147

  9. HUBBLE PICTURES SHOW HOT GAS BUBBLE EJECTED BY YOUNG STAR

    NASA Technical Reports Server (NTRS)

    2002-01-01

    These images taken with the Hubble Space Telescope's Wide Field and Planetary Camera 2 reveal the evolution of bubbles of glowing gas being blown out from the young binary star system XZ Tauri. Gas from an unseen disk around one or both of the stars is channeled through magnetic fields surrounding the binary system and then is forced out into space at nearly 300,000 miles per hour (540,000 kilometers per hour). This outflow, which is only about 30 years old, extends nearly 60 billion miles (96 billion kilometers). Hubble first discovered this unique bubble in 1995, and additional observations were made between 1998 and 2000. These images show that there was a dramatic change in its appearance between 1995 and 1998. In 1995, the bubble's edge was the same brightness as its interior. However, when Hubble took another look at XZ Tauri in 1998, the edge was suddenly brighter. This brightening is probably caused by the hot gas cooling off, which allows electrons in the gas to recombine with atoms, a process that gives off light. This is the first time that astronomers have seen such a cooling zone 'turn on.' These images provide an unprecedented opportunity to study the development of a very recent outflow from young (about 1 million years old) stars.

    and Chris Langdon, Brice Loose, Dwight Gledhill, Diana Hsueh, Derek Manzello, Ian Enochs, Ryan Moyer We present net ecosystem productivity (nep) and net ecosystem calcification (nec) in coral and seagrass ecosystems using the boundary layer gradient flux technique (CROSS). Coastal anthropogenic inputs and changes in global ocean chemistry in response to rising levels of atmospheric carbon dioxide has emerged in recent years as a topic of considerable concern. Coral reefs are particularly vulnerable from eroded environmental conditions including ocean acidification and water pollution. The Atlantic Ocean Acidification Testbed (AOAT) project monitors metabolism to ascertain the continuing health of coral reef ecosystems. The CROSS boundary layer nep/nec approach is one component of this diagnostic program. Certification of CROSS as an operational monitoring tool is underway in the AOAT. CROSS inspects a benthic community and measures productivity/respiration and calcification/dissolution over an area of 10 square meters. Being a boundary layer tool, advection and complex mesoscale flows are not a factor or concern and CROSS is autonomous and can be used at deep benthic sites. The interrogation area is not enclosed therefore exposed to ambient light, flow, and nutrient levels. CROSS is easy to deploy, unambiguous, and affordable. Repeated measurements have been made from 2011-2012 in reefal systems in La Parguera Puerto Rico and the Florida Keys, USA. Diurnal, seasonal and regional metabolism will be compared and discussed. The ability to accurately probe benthic ecosystems provides a powerful management and research tool to policy makers and researchers.

  11. CCBuilder: an interactive web-based tool for building, designing and assessing coiled-coil protein assemblies

    Motivation: The ability to accurately model protein structures at the atomistic level underpins efforts to understand protein folding, to engineer natural proteins predictably and to design proteins de novo. Homology-based methods are well established and produce impressive results. However, these are limited to structures presented by and resolved for natural proteins. Addressing this problem more widely and deriving truly ab initio models requires mathematical descriptions for protein folds; the means to decorate these with natural, engineered or de novo sequences; and methods to score the resulting models. Results: We present CCBuilder, a web-based application that tackles the problem for a defined but large class of protein structure, the α-helical coiled coils. CCBuilder generates coiled-coil backbones, builds side chains onto these frameworks and provides a range of metrics to measure the quality of the models. Its straightforward graphical user interface provides broad functionality that allows users to build and assess models, in which helix geometry, coiled-coil architecture and topology and protein sequence can be varied rapidly. We demonstrate the utility of CCBuilder by assembling models for 653 coiled-coil structures from the PDB, which cover >96% of the known coiled-coil types, and by generating models for rarer and de novo coiled-coil structures.

    Introduction Technical outreach - distinct from general-interest and K-12 educational outreach - for volcanic hazards is aimed at providing usable scientific information about potential or ongoing volcanic activity to public officials, businesses, and individuals in support of their response, preparedness, and mitigation efforts. Within the context of a National Volcano Early Warning System (NVEWS) (Ewert et al., 2005), technical outreach is a critical process, transferring the benefits of enhanced monitoring and hazards research to key constituents who have to initiate actions or make policy decisions to lessen the hazardous impact of volcanic activity. This report discusses recommendations of the Technical-Information Products Working Group convened in 2006 as part of the NVEWS planning process. The basic charge to the Working Group was to identify a web-based, volcanological 'product line' for NVEWS to meet the specific hazard-information needs of technical users.

    Simulation of the oxygen A band to a level that is sufficient for accurate studies of the Earth's atmosphere is complex in that not only are Doppler and Lorentz broadening important, but also Dicke narrowing, pressure shifts, line mixing and speed dependence. In addition all of these parameters except the speed dependence require temperature dependence parameters as well. To measure all of the required line parameters with the multispectrum nonlinear least squares fitting technique, spectra were acquired by the Bruker IFS125-HR Fourier Transform Spectrometer at the Jet Propulsion Laboratory in combination with various multpass cells, a cavity ring down spectrometer at NIST and a photoacoustic spectrometer at the California Institute of Technology. The combination of the data from these three very different types of spectrometers in a single simultaneous fit of the entire band enables the measurement of all of these quantities. The results to this point will be summarized. D. Chris Benner, C. P. Rinsland, V. M. Devi, M. A. H. Smith, and D. Atkins, JQSRT 1995;53:705-21.

  14. Kaiser Permanente's innovation on the front lines.

    The Innovation Consultancy, a small team within the health care provider Kaiser Permanente, practices an expansive, service-focused version of innovation that is both rapid and economical in comparison with the conventional version. The team's members observe how health care providers interact with one another, with technology, and with patients, and how the patients respond. They take photographs, draw pictures, write stories, and try to capture experiences from the point of view of everyone involved. During KP MedRite, a project to reduce the error rate in dispensing medication to hospital patients, the team asked nurses what they thought was wrong with the dispensing process. The nurses usually replied, "Nothing". But when given a chance to make self-portraits, they would draw themselves with sad faces and frazzled hair. Interruptions appeared to be the leading cause of errors-so one of the resulting innovations was a bright-yellow sash signaling that its wearer was not to be disturbed. KP's Chris McCarthy founded the Innovation Learning Network to accelerate knowledge transfer among peers in the nonprofit health care industry. One promising process that has emerged, Inflection Navigator, helps patients who've received a frightening diagnosis handle the consequent urgent tasks-follow-up tests, visits to specialists, decision making about treatment and care--with the aid of care coordinators. This innovation and others like it arise from a brand of creativity that transcends the media version of the health care debate. PMID:20821969

    Lake Champlain has bays undergoing chronic cyanobacterial harmful algal blooms that pose a public health threat. Monitoring and assessment tools need to be developed to support risk decision making and to gain a thorough understanding of bloom scales and intensities. In this research application, Landsat 8 Operational Land Imager (OLI), Rapid Eye, and Proba Compact High Resolution Imaging Spectrometer (CHRIS) images were obtained while a corresponding field campaign collected in situ measurements of water quality. Models including empirical band ratio regressions were applied to map chlorophylla and phycocyanin concentrations; all sensors performed well with R² and root-mean-square error (RMSE) ranging from 0.76 to 0.88 and 0.42 to 1.51, respectively. The outcomes showed spatial patterns across the lake with problematic bays having phycocyanin concentrations >25 μg/L. An alert status metric tuned to the current monitoring protocol was generated using modeled water quality to illustrate how the remote sensing tools can inform a public health monitoring system. Among the sensors utilized in this study, Landsat 8 OLI holds the most promise for providing exposure information across a wide area given the resolutions, systematic observation strategy and free cost.

    Videogames for health provide innovative, exciting, and possibly highly effective new media for helping players change their behaviors or otherwise benefit their health. Getting the right videogames into the hands of players who can benefit most in a way that pays for the continued innovation and creation of such games is a current challenge. Entertainment videogame companies, which create games primarily to enhance players' enjoyment, have used the general business marketplace (e.g., online stores, walk-in stores, app stores) to deliver their products directly to consumers and earn enough capital to invest in making new products. No one believes, however, that enough kids or adults would use the general business marketplace to purchase games for health in sufficient volume to provide the down payment for the innovation and creation of new games for health. A successful business model is critical to the financial future of games for health. We asked members of our Editorial Board who are in health-related companies (Fikry Isaac, MD, MPH), in several game development companies (Chris Ashford, Ron Goldman, David J. Lenihan, Brent Poole, and Richard Buday, FAIA), and the head of the Games for Health Europe Foundation (Jurriaan van Rijswijk, MSc) to address questions in a roundtable about the current and possible future business models for games for health.

    The Jordan Schnitzer Museum of Art in Eugene, Oregon, houses a remarkable permanent collection of Asian art and antiquities, modern art, and sculpture, and also hosts traveling exhibitions. In the winter and spring of 2011, a series of digital photographs by artist Chris Jordan, titled "Running the Numbers," was exhibited in the Coeta and Donald Barker Special Exhibitions Gallery. These works graphically illustrate waste (energy, money, health, consumer objects, etc.) in contemporary culture. The Bonneville Power Administration and the Eugene Water and Electricity Board provided a set of Cree 12W light-emitting diode (LED) PAR38 replacement lamps (Cree LRP38) for the museum to test for accent lighting in lieu of their standard Sylvania 90W PAR38 130V Narrow Flood lamps (which draw 78.9W at 120V). At the same time, the museum tested LED replacement lamps from three other manufacturers, and chose the Cree lamp as the most versatile and most appropriate color product for this exhibit. The lamps were installed for the opening of the show in January 2011. This report describes the process for the demonstration, the energy and economic results, and results of a survey of the museum staff and gallery visitors on four similar clusters of art lighted separately by four PAR38 lamps.

  1. Research on Streamlines and Aerodynamic Heating for Unstructured Grids on High-Speed Vehicles

    Engineering codes are needed which can calculate convective heating rates accurately and expeditiously on the surfaces of high-speed vehicles. One code which has proven to meet these needs is the Langley Approximate Three-Dimensional Convective Heating (LATCH) code. It uses the axisymmetric analogue in an integral boundary-layer method to calculate laminar and turbulent heating rates along inviscid surface streamlines. It requires the solution of the inviscid flow field to provide the surface properties needed to calculate the streamlines and streamline metrics. The LATCH code has been used with inviscid codes which calculated the flow field on structured grids, Several more recent inviscid codes calculate flow field properties on unstructured grids. The present research develops a method to calculate inviscid surface streamlines, the streamline metrics, and heating rates using the properties calculated from inviscid flow fields on unstructured grids. Mr. Chris Riley, prior to his departure from NASA LaRC, developed a preliminary code in the C language, called "UNLATCH", to accomplish these goals. No publication was made on his research. The present research extends and improves on the code developed by Riley. Particular attention is devoted to the stagnation region, and the method is intended for programming in the FORTRAN 90 language.

  3. What Do You Get When Two Neutron Stars Merge?

    NASA Astrophysics Data System (ADS)

    2015-10-01

    The merger of two neutron stars (a NSNS merger) is suspected to be the most likely source of short-duration gamma-ray bursts (GRBs) powerful explosions that can be seen from billions of light-years away. But whether a GRB is launched is dependent on what remnant is created by the merging NSs. Do they form another NS? Or a black hole (BH)?Uncertain RemnantIf the NSNS merger forms a BH remnant, a GRB can be launched during the ensuing accretion. But if it instead forms a NS, a GRB may only be launched if the remnant collapses to a BH within 100 milliseconds; any longer, and theory says that the GRB jet will become loaded with baryons and choke.Unfortunately, determining whether the merger will produce a NS or a BH is difficult. A major limitation is that we dont know what equation of state describes the interior of a NS which means we also dont know what maximum mass a NS can have before it collapses into a BH.Led by Chris Fryer of the University of Arizona and the Los Alamos National Laboratory, a group of researchers undertook a highly collaborative study to better understand the fates of NSNS mergers.Maximum MassThe fraction of mergers that produce BHs (and, consequently, GRBs) and NSs, as a function of the maximum NS mass allowed by the equation of state. Lines labeled BHAD are mergers that produce BHs (under two different initial conditions); lines labeled NS are those that produce NSs. [Fryer et al. 2015]The authors used a combination of merger calculations, neutron star equation of state studies, and population synthesis simulations to model the outcome of the merger of two NSs. With this information, they determined the statistical likelihood that the remnant that forms in the merger collapses directly to a BH, collapses to a BH after a delay, or remains a NS.Fryer and collaborators find that the outcome is highly dependent upon the maximum mass allowed by the uncertain NS equation of state. If this maximum NS mass is below 2.32.4 solar masses, most NS

    Remote sensing allows multi-temporal mapping and monitoring of large water bodies. The importance of remote sensing for wetland and inland water inventory and monitoring at all scales was emphasized several times by the Ramsar Convention on Wetlands and from EU projects like SALMON and ROSALMA, e.g. by (Finlayson et al., 1999) and (Lowry and Finlayson, 2004). This paper aims at assessing the capability of time series of satellite imagery to provide information suitable for enhancing the understanding of the temporal cycles shown by the macrophytes growing in order to support the monitor and management of the lake Victoria water resources. The lake Victoria coastal areas are facing a number of challenges related to water resource management which include growing population, water scarcity, climate variability and water resource degradation, invasive species, water pollution. The proliferation of invasive plants and aquatic weeds, is of growing concern. In particular, let us recall some of the problems caused by the aquatic weeds growing: Ø interference with human activities such as fishing, and boating; Ø inhibition or interference with a balanced fish population; Ø fish killing due to removal of too much oxygen from the water; Ø production of quiet water areas that are ideal for mosquito breeding. In this context, an integrated use of medium/high resolution images from sensors like MODIS, ASTER, LANDSAT/TM and whenever available CHRIS offers the possibility of creating a congruent time series allowing the analysis of the floating vegetation dynamic on an extended temporal basis. Although MODIS imagery is acquired daily, cloudiness and other sources of noise can greatly reduce the effective temporal resolution, further its spatial resolution can results not always adequate to map the extension of floating plants. Therefore, the integrated use of sensors with different spatial resolution, were used to map across seasons the evolution of the phenomena. The

    With a variety of high-quality live interactive educational programs originating at the Johnson Space Center in Houston, Texas and other space and research centers, the US space agency NASA (National Aeronautics and Space Administration) has a proud track record of connecting with students throughout the world and stimulating their creativity and collaborative skills by teaching them underlying scientific and technological underpinnings of space exploration. However, NASA desires to expand its outreach capability for this type of interactive instruction. In early 2002, NASA and the National Guard Bureau -- using the Guard's nationwide system of state-ofthe-art classrooms and high bandwidth network -- began a collaboration to extend the reach of NASA content and educational programs to more of America's young people. Already, hundreds of elementary, middle, and high school students have visited Guard e-Learning facilities and participated in interactive NASA learning events. Topics have included experimental flight, satellite imagery-interpretation, and Mars exploration. Through this partnership, NASA and the National Guard are enabling local school systems throughout the United States (and, increasingly, the world) to use the excitement of space flight to encourage their students to become passionate about the possibility of one day serving as scientists, mathematicians, technologists, and engineers. At the 54th International Astronautical Conference MAJ Stephan Picard, the guiding visionary behind the Guard's partnership with NASA, and Chris Chilelli, an educator and senior instructional designer at NASA, will share with attendees background on NASA's educational products and the National Guard's distributed learning network; will discuss the unique opportunity this partnership already has provided students and teachers throughout the United States; will offer insights into the formation by government entities of e-Learning partnerships with one another; and will

    A major dust storm transgressed over southeastern Australia in September 2009 and continued as far as northern Queensland [to the north], New Zealand and New Caledonia [to the east] . We analysed samples of the dust for organic compounds, its microbiological composition, pollen, trace and rare earth elements as well as Sr and Nd isotopes. Grain size analysis was also performed on some of the samples. We also obtained information on the meteorological conditions that led to the large dust plume and its pathway. Our geochemical fingerprinting allowed us to determine the origin of the dust, and this was confirmed by meteorological observations and satellite imagery. As the pathway of the dust plume went over the city of Canberra, located to the southwest of Sydney, we were able to collect samples of dust that fell with rain, and the surprise was that the geochemical composition of the dust varied with time [and dust fall], identifying that as the dust plume transgressed over the landscape, it picked up additional material that was compositionally different from its point of origin. We also compared our data with those obtained from another major dust event that affected Canberra in October 2002, and a number of important differences are noted, particularly with respect of the microbiological composition of the dust, and its chemical composition. Collaborators on this project are: Chris Munday and Gwen Allison [microbiology]: Research School of Biology, ANU; Jochen Brocks and Janet Hope [organic chemistry] and Marc Norman [inorganic geochemistry]: Research School of Earth Sciences, ANU; Tadhg O'Loingsigh and Nigel Tapper [meteorology, satellite imagery] and Sander van der Kaars [palynology]: Geography and Environmental Science, Monash University; and J.-B.

    Many companies face the challenge of balancing art with commerce. The conflict between corporate pragmatism and artistic passion and quality is persistent: designers chafe under corporate requirements, budgets, and deadlines, and nondesigners struggle to understand the business value of artistic choices. At German carmaker BMW, the fanaticism about design excellence is matched only by the company's driving desire to remain profitable. Global design director Chris Bangle presides over the intersection of art and commerce at BMW, managing the often-strained relationships among the designers, engineers, and business managers. Bangle goes to great lengths to protect his designers from the unproductive commentary of others in the company, literally posting "Stop: No Entry" signs on the design studio doors. He also protects the design process, making sure that time-to-market pressures do not harm the designs by shifting the focus to engineering too soon. As a mediator, Bangle appeals to the core values of the company and a deeply held sense about BMW-ness--a pride of product shared by everyone in the company that expresses itself in the classic quality of the cars. Every employee, designer and nondesigner alike, understands that if a car doesn't meet this standard of excellence, it's simply not a BMW--and customers won't buy it. Managing at the intersection of art and commerce means translating the language of art into the language of the corporation. In this First Person account, the author describes his inventive techniques for getting the best from his artists--and getting his ideas across to corporate managers. PMID:11189462

    Accurate modeling of atmospheric trace gases requires detailed knowledge of spectroscopic line parameters at temperatures and pressures relevant to the atmospheric layers where the spectroscopic signatures form. Pressure-broadened line shapes, frequency shifts, and their temperature dependences, are critical spectroscopic parameters that limit the accuracy of state-of-the-art atmospheric remote sensing. In order to provide temperature dependent parameters from controlled laboratory experiments, a 20.946 ± 0.001 m long path Herriott cell and associated transfer optics were designed and fabricated at Connecticut College to operate in the near infrared using a Bruker 125 HR Fourier transform spectrometer. The cell body and gold coated mirrors are fabricated with Oxygen-Free High Conductivity (OFHC) copper. Transfer optics are through-put matched for entrance apertures smaller than 2 mm. A closed-cycle Helium refrigerator cools the cell and cryopumps the surrounding vacuum box. This new system and its transfer optics are fully evacuated to ˜10 mTorr (similar to the pressure inside the interferometer). Over a period of several months, this system has maintained extremely good stability in recording spectra at gas sample temperatures between 75 and 250 K. The absorption path length and cell temperatures are validated using CO spectra. The characterization of the Herriott cell is described along with its performance and future applications. We thank Drs. V. Malathy Devi and D. Chris Benner at The College of William and Mary for helpful discussion. Research described in this paper was performed at Connecticut College, the Jet Propulsion Laboratory, California Institute of Technology, and NASA Langley Research Center, under contracts and cooperative agreements with the National Aeronautics and Space Administration.

Lengel (1998) Berett-Koehler Publishers, Inc." was Reviewed by Dr. Michelle Collins, NASA Headquarters. If you've already read books on leadership and organizational change by authors such as Moshe Rubinstein and Iris Firstenberg, Peter Senge, Tom Peters, and Steven Covey, and you were thinking of rereading them, you don't have to do that now. Just read this book instead. It's a fusion of many of their same concepts presented from a different view. The book does not explore any particular subject in depth. Rather the authors "skim" many subjects and concepts, interlacing them to develop the concept of "Fusion Leadership". The fundamental concept of treating people as people rather than machines is the main theme. "Fusion Leadership" is the process of fusing people together by nurturing six "subtle" forces: mindfulness, courage, vision, heart, communication, and integrity. To do so, hierarchy is diminished and responsibility both for oneself as well as for the team is emphasized. There are a number of organizations and managers that will find such a change threatening. The concepts behind such a management style are straightforward and the benefits are intuitive once you've reflected on them; however, the obvious benefits of the behavioral change proposed in Fusion Leadership can be completely lost in a fear-based system. The concept of caring about people in one's organization was the common thread in Chris Turner's book All Hat, No Cattle (see book review, ASK 5). Much is being written about the re-humanizing of the workplace, but the basis of it is so common sense that one wonders what's taking so long for the workplace to change? Whether you're in a position to change your organization or simply your project team, you'll find the concepts in fusion leadership equally applicable.

    The major research activities performed during the cooperative agreement enhanced our spectroscopic knowledge of molecules of atmospheric interest such as H2O (water vapor), O3 (ozone), HCN (hydrogen cyanide), CH4 (methane), NO2 (nitrogen dioxide) and CO (carbon monoxide). The data required for the analyses were obtained from two different Fourier Transform Spectrometers (FTS); one of which is located at the National Solar Observatory (NSO) on Kitt Peak, Arizona and the other instrument is located at the Pacific Northwest National Laboratories (PNNL) at Richland, Washington. The data were analyzed using a modified multispectrum nonlinear least squares fitting algorithm developed by Dr. D. Chris Benner of the College of William and Mary. The results from these studies made significant improvements in the line positons and intensities for these molecules. The measurements of pressure broadening and pressure induced line shift coefficients and the temperature dependence of pressure broadening and pressure induced shift coefficients for hundreds of infrared transitions of HCN, CO3 CH4 and H2O were also performed during this period. Results from these studies have been used for retrievals of stratospheric gas concentration profiles from data collected by several Upper Atmospheric Research Satellite (UARS) infrared instruments as well as in the analysis of high resolution atmospheric spectra such as those acquired by space-based, ground-based, and various balloon- and aircraft-borne experiments. Our results made significant contributions in several updates of the HITRAN (HIgh resolution TRANsmission) spectral line parameters database. This database enjoys worldwide recognition in research involving diversified scientific fields. The research conducted during the period 2003-2006 has resulted in publications given in this paper. In addition to Journal publications, several oral and poster presentations were given at various Scientific conferences within the United States

    Since fulfilling Austin Post’s prediction of impending retreat in the late 1970s, Columbia Glacier has repeatedly surprised both casual and careful observers with its ability for rapid change. Over the last three decades, Columbia Glacier has lost approximately 18 km of its original 66 km length, while thinning by approximately 50% at the present terminus. The total ice volume lost to the Gulf of Alaska Estimates upwards of 120 km3 constrain the total ice volume lost to the Gulf of Alaska. Recently, the terminus supported a ~1.5 km long floating tongue for over than a year, contradicting the common assumption that the mechanical properties of temperate ice prohibit flotation over sustained time intervals. The rich history of study offers an opportunity to better understand tidewater glacier retreat, and a valuable analog to the dynamic instability underway at several ice sheet outlet glaciers. Current research aims to improve processing resolution of existing aerial photographic data, while complimenting the 30-year photogrammetric record with a suite of field observations. Recent instrumentation includes: oblique time lapse and still imagery, semi-permanent GPS, airborne radar, mass balance, passive seismology and LiDAR. This presentation will focus on innovative methods developed in recent field seasons, sharing insight each has provided into the retreat process . 1The Columbia Glacier Consortium consists of: Fabian Walter (SIO), Kenichi Matsuoka (NPI), Ben Smith (UW), Ethan Welty (CU-Boulder), Chris Larsen (UAF), Dave Finnegan (CRREL), Dan McNamara (USGS), Yushin Ahn (OSU), Julie Markus (OSU), Adam LeWinter (EIS).

    FIRST LEGO League participants listen to Aerospace Education Specialist Chris Copelan explain the playing field for 'Nano Quest' during a recent FLL kickoff event at StenniSphere, the visitor center at NASA Stennis Space Center. The kickoff began the 2006 FLL competition season. Eighty-five teachers, mentors, parents and 9- to 14-year-old students from southern and central Mississippi came to SSC to hear the rules for Nano Quest. The challenge requires teams to spend eight weeks building and programming robots from LEGO Mindstorms kits. They'll battle their creations in local and regional competitions. The Dec. 2 competition at Mississippi Gulf Coast Community College will involve about 200 students. FIRST LEGO League, considered the 'little league' of the FIRST (For Inspiration and Recognition of Science and Technology) Robotics Competition, partners FIRST and the LEGO Group. Competitions aim to inspire and celebrate science and technology using real-world context and hands-on experimentation, and to promote the principles of team play and gracious professionalism. Because NASA advocates robotics and science-technology education, the agency and SSC support FIRST by providing team coaches, mentors and training, as well as competition event judges, referees, audio-visual and other volunteer staff personnel. Two of Mississippi's NASA Explorer Schools, Bay-Waveland Middle and Hattiesburg's Lillie Burney Elementary, were in attendance. The following schools were also represented: Ocean Springs Middle, Pearl Upper Elementary, Long Beach Middle, Jackson Preparatory Academy, North Woolmarket Middle, D'Iberville Middle, West Wortham Middle, Picayune's Roseland Park Baptist Academy and Nicholson Elementary, as well as two home-school groups from McComb and Brandon. Gulfport and Picayune Memorial-Pearl River high schools' FIRST Robotics teams conducted robotics demonstrations for the FLL crowd.

  16. The ultimate creativity machine. How BMW turns art into profit.

    Bangle, C

    2001-01-01

    Many companies face the challenge of balancing art with commerce. The conflict between corporate pragmatism and artistic passion and quality is persistent: designers chafe under corporate requirements, budgets, and deadlines, and nondesigners struggle to understand the business value of artistic choices. At German carmaker BMW, the fanaticism about design excellence is matched only by the company's driving desire to remain profitable. Global design director Chris Bangle presides over the intersection of art and commerce at BMW, managing the often-strained relationships among the designers, engineers, and business managers. Bangle goes to great lengths to protect his designers from the unproductive commentary of others in the company, literally posting "Stop: No Entry" signs on the design studio doors. He also protects the design process, making sure that time-to-market pressures do not harm the designs by shifting the focus to engineering too soon. As a mediator, Bangle appeals to the core values of the company and a deeply held sense about BMW-ness--a pride of product shared by everyone in the company that expresses itself in the classic quality of the cars. Every employee, designer and nondesigner alike, understands that if a car doesn't meet this standard of excellence, it's simply not a BMW--and customers won't buy it. Managing at the intersection of art and commerce means translating the language of art into the language of the corporation. In this First Person account, the author describes his inventive techniques for getting the best from his artists--and getting his ideas across to corporate managers.

  17. The Challenges and Achievements in 50 Years of Human Spaceflight

    NASA Astrophysics Data System (ADS)

    Hawley, Steven A.

    2012-01-01

    On April 12, 1961 the era of human spaceflight began with the orbital flight of Cosmonaut Yuri Gagarin. On May 5, 1961 The United States responded with the launch of Alan Shepard aboard Freedom 7 on the first flight of Project Mercury. The focus of the first 20 years of human spaceflight was developing the fundamental operational capabilities and technologies required for a human mission to the Moon. The Mercury and Gemini Projects demonstrated launch and entry guidance, on-orbit navigation, rendezvous, extravehicular activity, and flight durations equivalent to a round-trip to the Moon. Heroes of this epoch included flight directors Chris Kraft, Gene Kranz, and Glynn Lunney along with astronauts like John Young, Jim Lovell, Tom Stafford, and Neil Armstrong. The "Race to the Moon” was eventually won by the United States with the landing of Apollo 11 on July 20, 1969. The Apollo program was truncated at 11 missions and a new system, the Space Shuttle, was developed which became the focus of the subsequent 30 years. Although never able to meet the flight rate or cost promises made in the 1970s, the Shuttle nevertheless left a remarkable legacy of accomplishment. The Shuttle made possible the launch and servicing of the Hubble Space Telescope and diverse activities such as life science research and classified national security missions. The Shuttle launched more than half the mass ever put into orbit and its heavy-lift capability and large payload bay enabled the on-orbit construction of the International Space Station. The Shuttle also made possible spaceflight careers for scientists who were not military test pilots - people like me. In this talk I will review the early years of spaceflight and share my experiences, including two missions with HST, from the perspective of a five-time flown astronaut and a senior flight operations manager.

    2005-01-01

    The NASA History Division is pleased to present the record of a unique meeting on risk and exploration held under the auspices of the NASA Administrator, Sean O Keefe, at the Naval Postgraduate School in Monterey, California, from September 26-29, 2004. The meeting was the brainchild of Keith Cowing and astronaut John Grunsfeld, NASA's chief scientist at the time. Its goals, stated in the letter of invitation published herein, were precipitated by the ongoing dialogue on risk and exploration in the wake of the Columbia Shuttle accident, the Hubble Space Telescope servicing question, and, in a broader sense, by the many NASA programs that inevitably involve a balance between risk and forward-looking exploration. The meeting, extraordinarily broad in scope and participant experience, offers insights on why we explore, how to balance risk and exploration, how different groups defi ne and perceive risk differently, and the importance of exploration to a creative society. At NASA Headquarters, Bob Jacobs, Trish Pengra, and Joanna Adamus of NASA Public Affairs led the meeting's implementation. The Naval Postgraduate School, commanded by Rear Admiral Patrick W. Dunne, provided a congenial venue. The meeting was broadcast on NASA TV, and thanks are due in this regard to Al Feinberg, Tony Stewart, Jim Taylor, and the planners collaborative: Mark Shaddock and Spotlight Productions, Donovan Gates of Donovan Gates Production, and Michael Ditertay and his staff on this 30-person television crew. Thanks to their efforts, a DVD record of the meeting has also been produced. Thanks are also due to the moderators: Miles O Brien of CNN, Chris McKay of NASA Ames, David Halpern of the White House Office of Science and Technology Policy, and John Grunsfeld, NASA Headquarters.

  19. The reproductive health needs of refugees: emerging consensus attracts predictable controversy.

    1998-10-01

    According to the UN High Commissioner for Refugees, there are approximately 40 million refugees and other internally displaced people worldwide, with the overwhelming majority coming from and still living in developed countries. 80% of all refugees are estimated to be women and children. Many refugees spend months and even years in what are designed to be temporary settings where efforts are made to accommodate their basic needs such as food, clean water, shelter, security, and primary health care during emergency situations. Women refugees, however, have certain unique needs beyond what traditionally have been considered basic in relief programs. Many women in developing countries suffer considerable health risks during the best of times due to their poverty or low social status. When fleeing conflict or natural disaster, their health status is at even higher risk of being compromised by severe living conditions and the complete absence of reproductive health services. The recognition that women refugees often face serious and sometimes life-threatening reproductive health-related situations led to the development of a field manual on reproductive health for use at the local level. Planned for publication in late 1998 or early 1999, the guide will describe the goals of a minimum array of reproductive health services in the early phase of an emergency and provide direct guidance on care relating to sexual violence, STDs, family planning, adolescents' needs, and other reproductive health concerns such as female genital mutilation and treatment for septic and incomplete abortion. The manual has garnered worldwide attention and support, as well as scrutiny by abortion opponents in the US, in particular New Jersey Republican Representative Chris Smith.

  20. The Impact of the SESAME Project on Science and Society in the Middle East

    2008-04-01

    SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) is a UNESCO-sponsored project that is constructing an international research laboratory, closely modeled on CERN, in Jordan (www.sesame.org.jo). Ten Members of the governing Council (Bahrain, Cyprus, Egypt, Iran, Iraq, Israel, Jordan, Pakistan, Palestinian Authority, and Turkey) have responsibility for the project, led by Herwig Schopper, Council President since 1999. In late 2008 Chris Llewellyn-Smith will become Council President. SESAME was initiated by a gift from Germany of the decommissioned BESSY I facility. The BESSY I 0.8 GeV injector is now being installed in the recently completed building, funded by Jordan, as components are procured for a new 133 m circumference, 2.5 GeV third-generation storage ring with 12 locations for insertion devices. Beam line equipment has been provided by laboratories in France, UK, and US. Support also comes from EU, IAEA, ICTP, Japan Society for the Promotion of Science, the US Department of Energy and State Department, and laboratories around the world. The broad scientific program includes biomedical, environmental, and archaeological programs particularly relevant to the Middle East. Five scientific workshops and six annual Users' meetings have brought together several hundred scientists from the region, along with researchers from around the world. Training programs have enabled about 100 scientists from the region to work at synchrotron radiation laboratories. These activities have already had significant impact on science and society in the Middle East, for example leading to collaborations between scientists from countries that are not particularly friendly with each other, and to national planning emphasizing synchrotron radiation research. When research starts in 2011 this impact will grow as graduate students are trained in the region in many scientific disciplines, and scientists working abroad are attracted to return.

E-mail klr324@psu.eduUnderstanding and projecting future sea-level changes poses nontrivial challenges. Sea-level changes are driven primarily by changes in the density of seawater as well as changes in the size of glaciers and ice sheets. Previous studies have demonstrated that a key source of uncertainties surrounding sea-level projections is the response of the Antarctic ice sheet to warming temperatures. Here we calibrate a previously published and relatively simple model of the Antarctic ice sheet over a hindcast period from the last interglacial period to the present. We apply and compare a range of (pre-) calibration methods, including a Bayesian approach that accounts for heteroskedasticity. We compare the model hindcasts and projections for different levels of model complexity and calibration methods. We compare the projections with the upper bounds from previous studies and find our projections have a narrower range in 2100. Furthermore we discuss the implications for the design of climate risk management strategies.

  2. Electron-electron interactions and lattice distortions in the perovskite titanates

    NASA Astrophysics Data System (ADS)

    Bjaalie, Lars

    A two-dimensional electron gas (2DEG) with the unprecedented high density of 3x1014 (corresponding to 1/2 electron per interface unit cell area) can be formed at the interface between SrTiO3 and a rare-earth titanate (RTiO3). The 2DEG resides in the SrTiO3, and arises from a polar discontinuity at the interface. The formation of this 2DEG has led us to study these perovskite titanates in detail. Some of these compounds are Mott insulators, where a Mott-Hubbard gap opens up between partially filled Ti 3 d bands. This talk focuses on the importance of the interplay between electron-electron interactions and lattice distortions in these complex oxides, which we study with density functional theory using a hybrid functional, capable of correctly describing electron localization and Mott-insulating behavior. These effects are crucial to understanding the metal-to-insulator transition as a function of electron density. Indeed, very thin SrTiO3 layers inserted in GdTiO3 show insulating behavior, in contrast to the metallic character of thicker layers in which the electrons form a 2DEG. The same physics is observed in bulk SrTiO3 when doped with 1/2 electron per Ti atom. Charge localization and lattice distortions also govern the formation of small hole polarons in the rare-earth titanates. We demonstrate that these polarons impact the optical absorption measurements commonly used to determine the value of the Mott-Hubbard gap. Work performed in collaboration with Anderson Janotti, Burak Himmetoglu, and Chris G. Van de Walle, and supported by NSF and ARO.

  3. Hybrid functional studies of defects and hole polarons in oxides

    NASA Astrophysics Data System (ADS)

    Varley, Joel

    Transparent conducting oxides (TCOs) are ubiquitous, appearing in windows, flat-panel displays, solar cells, solid-state lighting, and transistors that all exploit TCOs' combination of high electrical conductivity and optical transparency. Thanks to this large and growing list of applications, there has been a surge of interest in the science of these materials, focusing on the fundamental properties and doping opportunities in traditional TCOs as well as the exploration of promising new candidate materials. Hybrid density functional theory has proven instrumental in elucidating the physics of TCOs. One example is the study of dopants and defects that determine the conductivity. Accurate formation energies and charge-state transition levels can now be obtained thanks to the accurate electronic structure provided by a hybrid functional. This allows us to address the origins of unintentional conductivity: for SnO2, In2O3, and Ga2O3, we demonstrate that this is not due to native defects such as oxygen vacancies, but must be attributed to unintentional incorporation of impurities. We can also provide guidelines for achieving higher doping levels, suggesting several impurities as candidate donors with high solubility. Limitations on doping due to the formation or incorporation of compensating centers are addressed as well. Hybrid functional calculations also overcome the shortcomings associated with traditional local or semi-local functionals, which do not properly describe charge localization. Hybrid functionals accurately describe polaron formation, i.e., the self-trapping of holes when p - type doping of the oxide materials is attempted. Consequences of polaron formation for optical characterization of the material will be discussed. This work was performed in collaboration with Anderson Janotti and Chris G. Van de Walle, and was in part under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

    2006-06-01

    Howard Malmstadt was a true giant of Analytical Chemistry and clearly one of the most influential analytical chemists of the last 50 years. Howard, through his own work and that of his students (first generation) and their students (second generation) and their students' students (third generation) changed the course of Analytical Chemistry. His research interests were broad and ranged from analytical solution chemistry (titrimetry and reaction rates) and electrochemistry to atomic and molecular spectroscopy, chemical instrumentation, clinical chemistry and automation. Howard was also one of the most innovative and influential educators of our time. He changed forever the analytical curriculum through his many books on Electronics for Scientists, most written in conjunction with Chris Enke and Stan Crouch. Their texts and short courses went from pioneering the application of tube-based analog electronics (servo systems and operational amplifiers) in scientific measurements to the impact that integrated circuits and digital electronics would have on laboratory measurements. He strongly believed in the importance of "hands-on" in education. To this end, he expended considerable personal effort and time to see not only the development and commercialization of an effective laboratory infrastructure to support education in analog and digital electronics, but also oversaw the development of modular instrumentation for spectroscopy. Over the years he received many awards from the Analytical Chemistry community for his outstanding efforts and contributions to teaching and research. Many of Howard's students went on into academia. They and their students now represent the ongoing legacy for analytical chemistry that evolved from Howard's laboratory at Illinois. A remarkable diversity of research programs are underway in their laboratories. Topics range from atomic, laser, mass, and Raman spectroscopy to detection technology, analytical education, micro

    2006-06-01

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

    Background Little is known regarding the health-related quality of life (HRQL) trajectory of children with sickle cell disease or thalassemia (“hemoglobinopathies”) following hematopoietic stem cell transplantation (HSCT). Procedure We serially evaluated the HRQL of 13 children with hemoglobinopathies who received HSCT during two prospective multi-center studies using the Child Health Ratings Inventories (CHRIs). The HRQL scores among children with hemoglobinopathies, as reported separately by the children and their parents were compared using repeated measures models to scores of a comparison group of children receiving HSCT for malignancies or severe aplastic anemia. Results The sample included 13 children with hemoglobinopathies (median age: 8 years, range 5–18) and 268 children in the comparison group (median age: 11 years, range 5–18). There were similar rates of early infection, chronic GVHD and all-cause mortality between the two groups. There was no significant difference in recovery to baseline scores for physical, emotional, and role functioning by three months for either group. Children with hemoglobinopathies had higher HRQL scores for physical (beta=12, se=5.5, p=0.01) and baseline emotional functioning (beta=11.6, se=5.5, p=0.03) than the comparison group. For all domains for both groups, parent reports demonstrated a nadir at 45 days with recovery to baseline by three months following transplant. Children’s ratings were higher than those of their parents in both diagnostic groups. Conclusions Children with hemoglobinopathies had higher physical and emotional functioning scores prior to HSCT and experienced a similar pattern of recovery to their baseline functioning by three months post-HSCT when compared to children receiving HSCT for acquired conditions.

    2007-02-16

    This project examined the internal architecture of delta front sandstones at two locations within the Turonian-age Wall Creek Member of the Frontier Formation, in Wyoming. The project involved traditional outcrop field work integrated with core-data, and 2D and 3D ground penetrating radar (GPR) imaging from behind the outcrops. The fluid-flow engineering work, handled through a collaborative grant given to PI Chris White at LSU, focused on effects on fluid flow of late-stage calcite cement nodules in 3D. In addition to the extensive field component, the work funded 2 PhD students (Gani and Lee) and resulted in publication of 10 technical papers, 17 abstracts, and 4 internal field guides. PI Bhattacharya also funded an additional 3 PhD students that worked on the Wall Creek sandstone funded separately through an industrial consortium, two of whom graduated in the fall 2006 ((Sadeque and Vakarelov). These additional funds provided significant leverage to expand the work to include a regional stratigraphic synthesis of the Wall Creek Member of the Frontier Formation, in addition to the reservoir-scale studies that DOE directly funded. Awards given to PI Bhattacharya included the prestigious AAPG Distinguished Lecture Award, which involved a tour of about 25 Universities and Geological Societies in the US and Canada in the fall of 2005 and Spring of 2006. Bhattacharya gave two talks, one entitled “Applying Deltaic and Shallow Marine Outcrop Analogs to the Subsurface”, which highlighted the DOE sponsored work and the other titled “Martian River Deltas and the Origin of Life”. The outcrop analog talk was given at about 1/2 of the venues visited.

    The status and trend of degradation in the world’s Drylands, that support over 1.2 billion people, is unknown because monitoring & assessment has not occurred on a globally consistent basis and skilled personnel with a cultivated interest in natural resource science and management are lacking. A major monitoring dataset is the 37-year Landsat data archive that has been released free to the world, but this dataset requires persons who understand how to process and interpret this and similar datasets applicable to the desertification problem. The College of Agriculture & Life Sciences (COALS) at Texas A&M University (TAMU) has an initiative to provide undergraduates with both international and research experiences. The lead author used start-up money, USFS project funds for livestock footprint studies in the US, and seed money from COALS to 1) develop academic mentor contacts in Mozambique, Namibia, Botswana, South Africa, and Tunisia to prepare a National Science Foundation Research Experience for Undergraduates (NSF-REU) Site proposal and 2) launch a pilot REU for two TAMU undergraduate students. Mr. Delgado and Mr. Redman received lidar processing and visualization, field survey training on global positioning systems (GPS), terrestrial LIDAR, and ground penetrating radar technologies and conducted carbon change studies by collecting pre- and post-fire laser scans on experimental burn (EPB) sites in Texas and South Africa. Mr. Redman also developed GIS databases of Landsat timeseries for these EPBs and others in southern Africa. Mr. Delgado participated in the Savanna Fire Ignition Research Experiment (SavFIRE) in Kruger National Park (KNP) by collected laser scan data on 3 EPBs. He also received mentoring from Dr. Winston Trollope, a prominent fire ecologist, and Mr. Chris Austin both of Working with Fire International and Navashni Govender, KNP’s Fire Ecologist. He also was an active participant in a NASA sponsored workshop on remote sensing of global

    Astronomers have used NASA's Hubble Space Telescope to probe the core of the nearest active galaxy to Earth, Centaurus A. [UPPER LEFT] - A close-up high resolution Wide Field Planetary Camera 2 image of the dramatic dust disk which is thought to be the remnant of a smaller spiral galaxy that merged with the large elliptical galaxy. The shock of the collision compressed interstellar gas, precipitating a flurry of star formation and giving the material a fleecy pattern. Dark filaments of dust mixed with cold hydrogen gas are silhouetted against the incandescent yellow-orange glow from stars behind it. [LOWER RIGHT] - Hubble's Near Infrared Camera and Multi-Object Spectrometer was used to peer past the dust to discover a tilted disk of hot gas at the galaxy's center (white bar running diagonally across image center). This 130 light-year diameter disk encircles a suspected black hole which may be one billion times the mass of our Sun. The disk feeds material to presumably an inner, unresolved accretion disk that is made up of gas entrapped by the black hole. The red blobs near the disk are glowing gas clouds which have been heated up and ionized by the powerful radiation from the active nucleus. The false-color NICMOS image was taken on Aug. 11, 1997 at a wavelength of 1.87 microns ('Paschen alpha'), characteristic of ionized Hydrogen.

    What could be more fundamental to management, or more difficult, than motivating people? After all, a manager, by definition, is someone who gets work done through others. But how? A typical recipe for motivation calls for a mixture of persuasion, encouragement, and compulsion. Yet the best leaders, we suspect, need no recipe: They get people to produce great results by appealing to their deepest drives, needs, and desires. And so we discovered when we asked a dozen of the world's top leaders to describe how they each met a daunting challenge in motivating an individual, a team, or an organization. Their answers are as varied as human nature. Some of the leaders appeal to people's need for the rational and the orderly: Mattel's Robert Eckert emphasizes the reassuring power of delivering a consistent message, and HP's Carly Fiorina focuses on facing hard truths on setting step-by-step goals. Some, like celebrated oceanographer Robert Ballard, Pfizer CEO Hank McKinnell, and BP America president Ross Pillari, see the powerful motivating effects of asking people to rise to difficult challenges. Others focus more on the human spirit, appealing to the desire to do something, as BMW's Chris Bangle puts it, "rare, marvelous, and lasting." And quite a few inspire through example, as Dial chairman Herb Baum did when he donated $1,000 from his bonus to each of the company's 155 lowest-paid people. "If you draw the line on your own greed, and your employees see it," he says, "they will be incredibly loyal and perform much better for you." And he has the numbers to prove it. "Right now," he adds, "we're experiencing our lowest level of attrition in 11 years, and we're tracking toward another banner year because people are happy."

  12. On the Thermal Anomaly of Lake Untersee

    2015-01-01

    Reported here is the outcome from a student internship undertaken with Dr. Chris McKay at the NASA Ames Research Center. The project for this internship focuses on Lake Untersee, an Earth analog for icy moons. The anoxic hole of Lake Untersee has a thermal bump that was first observed by Wand et al., 1997 and has been confirmed several times (Wand et al., 2006; Andersen 2011). The expected thermal profile of the hole is linear from 0 C at the thermocline to approximately 4 C, the ground temperature in Antarctica, at the bottom. Instead, there is an increase from 0 C near the thermocline to 5 C which is maintained for 7 m, then a linear profile to approximately 4 C near the bottom. Thermal modeling was conducted to quantify the energy input required to maintain the bump. The results revealed 2 sources. Chemical reactions and radiative energy were analyzed as possible explanation. The chemical analysis revealed a peak in Chlorophyll a at the same depth as the shallower source and several interesting reactions with maximum rates at the same location as the lower depth source. However, the energy released from these reactions was orders of magnitude smaller than required source. The radiation analysis revealed a profile with two peaks in similar locations to the sources and a total energy input within a factor of 1.5 of the required sources. The conclusion from this work is that photosynthesis and the chemical reactions support microbial life in the water column which in turn acts as an opacity to convert radiative energy into thermal energy. Recommendations for future work are aimed at quantifying the quantity and types of microbes present in the water column. Beyond the work of the project, two field trips are described and a discussion on benefits to the student of the internship is given.

    Supply chain management is all about software and systems, right? Put in the best technology, sit back, and watch as your processes run smoothly and the savings roll in? Apparently not. When HBR convened a panel of leading thinkers in the field of supply chain management, technology was not top of mind. People and relationships were the dominant issues of the day. The opportunities and problems created by globalization, for example, are requiring companies to establish relationships with new types of suppliers. The ever-present pressure for speed and cost containment is making it even more important to break down stubbornly high internal barriers and establish more effective cross-functional relationships. The costs of failure have never been higher. The leading supply chain performers are applying new technology, new innovations, and process thinking to far greater advantage than the laggards, reaping tremendous gains in all the variables that affect shareholder value: cost, customer service, asset productivity, and revenue generation. And the gap between the leaders and the losers is growing in almost every industry. This roundtable gathered many of the leading thinkers and doers in the field of supply chain management, including practitioners Scott Beth of Intuit, Sandra Morris of Intel, and Chris Gopal of Unisys. David Burt of the University of San Diego and Stanford's Hau Lee bring the latest research from academia. Accenture's William Copacino and the Warren Company's Robert Porter Lynch offer the consultant's perspectives. Together, they take a wide-ranging view of such topics as developing talent, the role of the chief executive, and the latest technologies, exploring both the tactical and the strategic in the current state of supply chain management.

    Companies in many industries are feeling immense pressure to improve their ability to innovate. Even in these tough economic times, executives have pushed innovation initiatives to the top of their priority lists, but they know that the best ideas aren't always coming out of their own R&D labs. That's why a growing number of companies are exploring the idea of open-market innovation--an approach that uses tools such as licensing, joint ventures, and strategic alliances to bring the benefits of free trade to the flow of new ideas. For instance, when faced with the unanticipated anthrax scare last fall, Pitney Bowes had nothing in its R&D pipeline to help its customers combat the deadly spores. So it sought help from outside innovators to come up with scanning and imaging technologies that could alert its customers to tainted letters and packages. And Dow Chemical and Cargill jointly produced a new form of plastic derived from plant starches--a breakthrough product that neither company could have created on its own. In this article, Bain consultants Darrell Rigby and Chris Zook describe the advantages and disadvantages of open-market innovation and the ways some companies are using it to gain competitive advantage. By importing ideas from the outside, the authors say, companies can collect more and better ideas from different kinds of experts. Creative types within a company will stick around longer if they know their ideas will eventually find a home--as internal R&D projects or as concepts licensed to outside buyers. Exporting ideas also gives companies a way to measure an innovation's real value. However, the authors warn against entering into open-market innovation without properly structuring deals: Xerox and TRW virtually gave away their innovations and had to stand by while other companies capitalized on them.

    The twentieth century has seen the greatest advances in science and technology in the history of the world. These advances spawned a golden age in astronomy and in the astronomical instrumentation that fueled it. This paper will summarize 31 years of development of high-resolution spectroscopic instrumentation at McDonald Observatory, from the construction of the 2.7-m Harlan J. Smith Telescope and its coudé spectrograph through the completion of the 9.2-m Hobby-Eberly Telescope with its high-resolution fiber-fed spectrograph. We begin with photographic spectroscopy and advance through rapid-scanning photon counting spectrometry under computer control, addition of echelle gratings, Reticon and self-scanned Digicon solid-state imaging detectors, and innovative cross-dispersed echelle spectrometers with large-format CCDs. Funding for all these projects by the National Science Foundation and the National Aeronautics and Space Administration is gratefully acknowledged, as are additional support from University of Texas matching grants and from the Texas state legislature. Thanks also to the many colleagues who have shared this adventure with me: Ed Nather, who taught me computer interfacing techniques; Johnnie Floyd, Don Wells, Steve Vogt, Phil Kelton, Richard Stover, Brenda Young, Phillip MacQueen, David Doss, John Good, Harland Epps, and Mark Cornell, who were involved in various phases of instrument development; and Hans Dekker, who shared ideas developed at ESO. The users developed the observing and data reduction techniques; among these are David Lambert, Chris Sneden, Ed Barker, Larry Trafton, Joc Tomkin, and many others. Tom Barnes and Frank Bash provided moral and logistical support, and Joyce Sampson spent many hours in fund-raising efforts. Finally, I wish to dedicate this work to the memory of Harlan J. Smith who gave unswerving encouragement and support over a period of many years.

    The science activities are: 1) Hydra is still operating successfully on orbit. 2) A large amount of analysis and discovery has occurred with the Hydra ground data processing this past year. 3) Full interdetector calibration has been implemented and documented. This intercalibration was necessitated by the incorrect installation of bias resistors in the pre-acceleration stage to the electron channeltrons. This had the effect of making the counting efficiency for electrons energy dependent as well as channeltron specific. The nature of the error had no impact on the ion detection efficiency since they have a different bias arrangement. This intercalibration is so effective, that the electron and ion moment densities are routinely produced with a level of agreement better than 20%. 4) The data processing routinely removes glint in the sensors and produces public energy time spectrograms on the web overnight. 6) Routine, but more intensive computer processing codes are operational that determine for electrons and ions, the density, the flow vector, the pressure tensor and the heat flux by numerical integration. These codes use the magnetic field to sustain the quality of their output. To gain access to this high quality magnetic field within our data stream we have monitored Russell's web page for zero levels and timing files (since his data acquisition is not telemetry synchronous) and have a local reconstruction of B for our use. We have also detected a routine anomaly in the magnetometer data stream that we have documented to Chris Russell and developed an editing algorithm to intercept these "hits" and remove them from the geophysical analysis.

    Amanda Williams qualified as a clinical psychologist in 1985. She joined the first residential pain management programme, INPUT, at St Thomas' Hospital (London, UK) at its start in 1988, running the research program, initially a large randomized controlled trial and generalization trial, and then a series of studies nested within the ongoing program. In 1996 she completed her PhD on the psychology of pain management and took a part-time academic post in the Guy's, King's & St Thomas' medical school (London, UK). In 2004, she moved to University College London (UK), teaching and supervising undergraduate and postgraduate psychologists, and continuing some clinical work in the long-established Pain Management Centre of the National Hospital (London, UK). For over 10 years she has been a volunteer and then a consultant at the Medical Foundation for Victims of Torture (London, UK) working clinically and developing audit and evaluation of clinical work there. She continues these strands of work and they include: evaluation of psychological methods of pain management, mainly in systematic reviews with Chris Eccleston and Stephen Morley; and understanding chronic pain from torture. She has worked extensively on facial expression of pain and its recognition by others, applying an explicitly evolutionary model. This work has led to a major grant to develop automated therapeutic feedback to people with pain, using their behavior as input. She has spoken at many national and international pain meetings, including a plenary at the World Congress of Pain in 2002; she has published over 100 papers and chapters and is on the editorial boards of several major pain journals.

    Deep-space missions have been unable to react to dynamic events as encounter observation sequences are planned well in advance. In the case of planet, asteroid and comet fly-bys, the limited resources available are allocated to individual instruments long beforehand. However, for monitoring or mapping mission phases, alternative strategies and technologies are now available. Now, onboard data processing allows greater spacecraft and instrument flexibility, affording the ability to react rapidly to dynamic events, and increasing the science content of returned data. Such new technology has already been successfully demonstrated in the form of the New Millennium Program Autonomous Sciencecraft Experiment (ASE). In 2004 ASE successfully demonstrated advanced autonomous science data acquisition, processing, and product downlink prioritization, as well as autonomous fault detection and spacecraft command and control. ASE is software onboard the EO-1 spacecraft, in Earth-orbit. ASE controlled the Hyperion instrument, a hyperspectral imager with 220 wavelengths from 0.4 to 2.5 μm and 30 m/pixel spatial resolution. ASE demonstrated that spacecraft autonomy will be advantageous to future missions by making the best use of limited downlink, e.g., by increasing science content per byte of returned data, and by avoiding the return of null (no-change/no feature) datasets. and by overcoming communication delays through decision-making onboard enabling fast reaction to dynamic events. We envision this flight-proven science-driven spacecraft command-and-control technology being used on a wide range of missions to search for and monitor dynamic events, such as active, high-temperature volcanism on Earth and Io, and cryovolcanism on Triton and possibly other icy satellites.

    The DISCRETE 2014: Fourth Symposium in the Physics of Discrete Symmetries took place at King's College London, Strand Campus, London WC2R 2LS, from Tuesday, December 2 2014 till Saturday, December 6 2014. This is the fourth Edition of the DISCRETE conference series, which is a biannual event, having been held previously in Valencia (Discrete'08), Rome (Discrete2010) and Lisbon (Discrete2012). The topics covered at the DISCRETE series of conferences are: T, C, P, CP symmetries; accidental symmetries (B, L conservation); CPT symmetry, decoherence and entangled states, Lorentz symmetry breaking (phenomenology and current bounds); neutrino mass and mixing; implications for cosmology and astroparticle physics, dark matter searches; experimental prospects at LHC, new facilities. In DISCRETE 2014 we have also introduced two new topics: cosmological aspects of non-commutative space-times as well as PT symmetric Hamiltonians (non-Hermitian but with real eigenvalues), a topic that has wide applications in particle physics and beyond. The conference was opened by the King's College London Vice Principal on Research and Innovation, Mr Chris Mottershead, followed by a welcome address by the Chair of DISCRETE 2014 (Professor Nick E. Mavromatos). After these introductory talks, the scientific programme of the DISCRETE 2014 symposium started. Following the tradition of DISCRETE series of conferences, the talks (138 in total) were divided into plenary-review talks (25), invited research talks (50) and shorter presentations (63) — selected by the conveners of each session in consultation with the organisers — from the submitted abstracts. We have been fortunate to have very high-quality, thought stimulating and interesting talks at all levels, which, together with the discussions among the participants, made the conference quite enjoyable. There were 152 registered participants for the event.

  1. Cosmic Noise: The Pioneers of Early Radio Astronomy and Their Discoveries

    Sullivan, Woodruff T., III

    2012-01-01

    Extraterrestrial radio waves (the galactic background), often referred to as "cosmic noise", were first detected accidentally by Karl Jansky at a frequency of 20 MHz in 1932, with significant followup by Grote Reber. Yet after World War II it was England and Australia that dominated the field. An entirely different sky from that of visual astronomy was revealed by the discoveries of solar noise, "radio stars” (discrete sources such as Cas A, Tau A, Cyg A, Cen A and Vir A), galactic noise, lunar and meteor radar experiments, the detection of the 21 cm hydrogen line, and eventually optical identifications such as the Crab Nebula and M87. Key players included wartime radar experts such as Stanley Hey (the British Army's Operational Research Group), Martin Ryle (Cambridge University), Bernard Lovell (Jodrell Bank) and Joe Pawsey (Radiophysics Lab, Sydney). Younger leaders also emerged such as Graham Smith, Tony Hewish, John Davies, "Chris" Christiansen, Bernie Mills, Paul Wild, and John Bolton. Some optical astronomers (Jan Oort, Henk van de Hulst, Jesse Greenstein, Rudolph Minkowski, and Walter Baade) were also extremely supportive. By the end of the postwar decade, radio astronomy was firmly established within the gamut of astronomy, although very few of its practitioners had been trained as astronomers. I will also trace the technical and social aspects of this wholly new type of astronomy, with special attention on military and national influences. I argue that radio astronomy represents one of the key developments in twentieth century astronomy not only because of its own discoveries, but also its pathfinding for the further opening the electromagnetic spectrum. This study is based on exhaustive archival research and over one hundred interviews with pioneering radio astronomers. Full details are available in the book "Cosmic Noise: A History of Early Radio Astronomy" (Cambridge Univ. Pr.).

  2. Multispectrum Fitting of FTS and Crds Spectra Simultaneously

    Various types of spectra contain different sorts of spectral line information. An FTS spectrum provides broad coverage of an identical sample at all parts of the spectrum, but a cavity ring down spectrometer provides higher resolution, more information about line shapes and greater dynamic range in spectral line intensity. In order to use all of the information available, one should put all the spectra available into a single solution. The multispectrum nonlinear least squares fitting technique has proven successful in doing this with transmission spectra from various spectrometers. However, fitting data from cavity ring down spectrometers that produce cross sections is a problem when combined with transmission spectrometers. The solution is to choose a path length for the CRDS data to produce transmissions and use the uncertainty of each cross section as a means of weighting the transmission in the multispectrum solution. This has been incorporated into our fitting technique. Sample oxygen A band fits of CRDS data from NIST combined with FTS data from a high resolution Fourier transform spectrometer in the Infrared, Bruker IFS125-HR, at JPL, equipped with two multipass White cells (absorption path length extendible to 32.5 m and 148 m, respectively) will be shown.

    Magnetic nanoparticles conjugated with biomolecules or recognition moieties are finding wide applications in medicine. In this context, we are developing a micromachined magnetic sifter and magnetic nanoparticles aimed for sample preparation applications in early diagnosis of cancer. The microfabricated sifter consisting of arrays of micron sized slits etched through a silicon wafer. A magnetic film is deposited on the wafer, producing high magnetic field gradients, comparable in magnitude to gradients in planar flow devices. As the solution flows through the die, magnetic particles are captured by the magnetic material surrounding the slits. The large number of slits allows for processing of large volumes of liquid, much greater than that of planar microfluidic devices. The sifters can be simply attached to a syringe or tube, resulting in a portable and user-friendly tool for molecular biology. Separation efficiencies of ˜ 50% for one pass through the sifter have been achieved. We have also designed and fabricated several types of magnetic biochips consisting of arrays of giant magnetoresistive (GMR) spin valve detectors with appropriate dimensions, surface chemistry, and microfluidics. An advanced electronic test station has been set up as a demonstration vehicle for the integrated evaluation of our magnetic biochips with commercial and custom magnetic nanoparticle labels for DNA or protein biomarkers. The magnetic biochip is capable of detecting down to 1-30 nanotags. Real-time detection of DNA signatures and protein targets in buffer and serum samples has been successfully performed in our laboratories, suggesting that magnetic biochips hold great promises for molecular diagnostics of cancer and other diseases.

    "Live from the Poles" tells the stories of science on ice. This NSF-sponsored education and outreach project (polardiscovery.whoi.edu) aims to go beyond results and sound bites to convey the full experience of polar research with all its trials, triumphs, and nuances. It uses a multimedia approach, including online photo essays posted daily during expeditions, along with videos, interviews, podcasts, animations, and audio clips-plus live satellite phone calls to audiences in major museums and science centers throughout the country. Our media team, typically a science writer and photographer, are embedded into the research program for the duration of the project. They live in the polar environment with the science party, bolstering their ability to convey the "human side" of the story that engages the public: What inspired the researchers to study the Arctic? What do they eat for dinner? How do they cope with the environment and being away from home? What other unexpected challenges will arise and how will they be overcome? The first expedition, in April 2007, shared the excitement of working in Nunavut, Canada, as researchers prepared to deploy instruments at the North Pole Environmental Observatory. The second followed an international scientific team's search for hydrothermal vents aboard the Swedish icebreaker Oden in July-August 2007. The Polar Discovery Web site has attracted more than 74,000 online visitors in its first eight months of operation. During the first two expeditions, the project facilitated 15 live audio talks to museum audiences, media outlets, and teacher workshops. This presentation will focus on lessons learned from the first two expeditions, with perspectives on science reporting and writing in the field from a science writer at AGU, and on the art of documentary photography, from photographer and project manager Chris Linder, who will speak via satellite phone from the third Polar Discovery expedition in Antarctica.

    Spatially explicit and temporally continuous estimates of photosynthesis will be of great importance for increasing our understanding of and ultimately closing the terrestrial carbon cycle. Current capabilities to model photosynthesis, however, are limited by accurate enough representations of the complexity of the underlying biochemical processes and the numerous environmental constraints imposed upon plant primary production. A potentially powerful alternative to model photosynthesis through these indirect observations is the use of multi-angular satellite data to infer light-use efficiency (e) directly from spectral reflectance properties in connection with canopy shadow fractions. Hall et al. (this issue) introduced a new approach for predicting gross ecosystem production that would allow the use of such observations in a data assimilation mode to obtain spatially explicit variations in e from infrequent polar-orbiting satellite observations, while meteorological data are used to account for the more dynamic responses of e to variations in environmental conditions caused by changes in weather and illumination. In this second part of the study we implement and validate the approach of Hall et al. (this issue) across an ecologically diverse array of eight flux-tower sites in North America using data acquired from the Compact High Resolution Imaging Spectroradiometer (CHRIS) and eddy-flux observations. Our results show significantly enhanced estimates of e and therefore cumulative gross ecosystem production (GEP) over the course of one year at all examined sites. We also demonstrate that e is greatly heterogeneous even across small study areas. Data assimilation and direct inference of GEP from space using a new, proposed sensor could therefore be a significant step towards closing the terrestrial carbon cycle.

(HCI), Littleton, Colorado. Mr. Chris Colucci was NREL`s Technical Monitor. Colorado State University`s (CSU) Engines and Energy Conversion Laboratory was HCI`s subcontractor. Some of the vehicle test work was carried out at the National Center for Vehicle Emissions Control and Safety (NCVECS) at CSU. The collaboration of the Colorado School of Mines is also gratefully acknowledged. Hydrogen is unique among alternative fuels in its ability to burn over a wide range of mixtures in air with no carbon-related combustion products. Hydrogen also has the ability to burn on a catalyst, starting from room temperature. Hydrogen can be made from a variety of renewable energy resources and is expected to become a widely used energy carrier in the sustainable energy system of the future. One way to make a start toward widespread use of hydrogen in the energy system is to use it sparingly with other alternative fuels. The Phase I work showed that strong affects could be achieved with dilute concentrations of hydrogen in methane (11). Reductions in emissions greater than the proportion of hydrogen in the fuel provide a form of leverage to stimulate the early introduction of hydrogen. Per energy unit or per dollar of hydrogen, a greater benefit is derived than simply displacing fossil-fueled vehicles with pure hydrogen vehicles.

    Sullivan, Chris T

    2005-09-01

    When Chris Sullivan and three friends opened the first Outback Steakhouse in March 1988, in Tampa, Florida, they were hoping it would be successful enough to spawn a few more and maybe some other kinds of restaurants as well. Since then, their chain of Australia-themed restaurants has grown to some 900 locations and counting-plus another 300 or so "concept" restaurants that operate from under Outback's corporate umbrella. Growth like that doesn't happen accidentally, Sullivan says, but it certainly wasn't part of the original plan. In this first-person account, Outback's chairman describes the organization's formula for growth and development, which is consciously rooted in the founders' belief in putting people first. They've created an organizational model in which field managers make most of the decisions, garner the rewards, and live with the consequences. Specifically, the founders believe that the most effective way to make customers happy is to first take care of the people who cook for them, serve them, and supervise operations at the restaurants. Outback servers have fewer tables to worry about than those at other restaurant chains; the cooks have bigger, cooler, better-equipped kitchens; and the supervisors work their way up the ranks toward an equity stake in the restaurant or region they run. There are no administrative layers between field managers and the executives at headquarters. Giving employees good working conditions and the chance to become owners has proved to be good business: Turnover among hourly employees is low, and Outback and its subsidiaries opened 120 restaurants last year, increasing sales by 20.1%. The company must grow in order to keep offering career opportunities to its workers; in turn, those opportunities ensure that Outbackers remain committed to making customers happy and the company successful.

    1996-12-01

    In collaboration with NASA GSFC, we have examined a wide range of potential concepts for a large, passively cooled space telescope. Our design goals were to achieve a theoretical imaging sensitivity in the near-IR of 1 nJy and an angular resolution at 1 micron of 0.06 arcsec. Concepts examined included a telescope/spacecraft system with a 6-m diameter monolithic primary mirror, a variety of telescope/spacecraft systems with deployable primary mirror segments to achieve an 8-m diameter aperture, and a 12-element sparse aperture phased array telescope. Trade studies indicate that all three concept categories can achieve the required sensitivity and resolution, but that considerable technology development is required to bring any of the concepts to fruition. One attractive option is the system with the 6-m diameter monolithic primary. This option achieves high sensitivity without telescope deployments and includes a stiff structure for robust attitude and figure control. This system capitalizes on coming advances in launch vehicle and shroud technology, which should enable launch of large, monolithic payloads into orbit positions where background noise due to zodiacal dust is low. Our large space telescope study was performed by a consortium of organizations and individuals including: Domenick Tenerelli et al. (Lockheed Martin Corp.), Roger Angel et al. (U. Ariz.), Tom Casey et al. (Eastman Kodak Co.), Jim Gunn (Princeton), Shel Kulick (Composite Optics, Inc.), Jim Westphal (CIT), Johnny Batache et al. (Harris Corp.), Costas Cassapakis et al.

    Validation of remote sensing land products is a fundamental issue for Earth observation. Ministry of Science and Technology of the People's Republic of China (MOST) has launched a high-tech R&D Program named `Development and experimental verification of key techniques to validate remote sensing products' in 2011. This paper introduces the background, scientific objectives, research contents of this project and research result already achieved. The objectives of this project include (1) to build a technical specification for the validation of remote sensing products; (2) to investigate the performance, we will carry out a comprehensive remote sensing experiment on satellite - aircraft - ground truth and then modify Step 1 until reach the predefined requirement; (3) to establish a validation network of China for remote sensing products. In summer 2012, with support of the Heihe Watershed Allied Telemetry Experimental Research (HiWATER), field observations have been successfully conducted in the central stream of the Heihe River Basin, a typical inland river basin in northwest China. A flux observation matrix composed of eddy covariance (EC) and large aperture scintillometer (LAS), in addition to a densely distributed eco-hydrological wireless sensor network have been established to capture multi-scale heterogeneities of evapotranspiration (ET), leaf area index (LAI), soil moisture and temperature. Airborne missions have been flown with the payloads of imaging spectrometer, light detection and ranging (LiDAR), infrared thermal imager and microwave radiometer that provide various scales of aerial remote sensing observations. Satellite images with high resolution have been collected and pre-processed, e.g. PROBA-CHRIS and TerraSAR-X. Simultaneously, ground measurements have been conducted over specific sampling plots and transects to obtain validation data sets. With this setup complex problems are addressed, e.g. heterogeneity, scaling, uncertainty, and eventually to

  13. Penetrating arterial trauma to the limbs: outcome of a modified protocol

    PubMed Central

    2013-01-01

    Background Penetrating arterial injuries to the limbs are common injuries in high volume trauma centers. Their overall surgical results reported in the literature are satisfactory - apart of those of the popliteal artery that still may lead to a significant incidence in amputations. With the present study we assessed our outcome with penetrating arterial injuries to the limb as to see if the direct involvement of vascular surgeons in the management of popliteal artery injuries leads to an improved (lowered) amputation rate. Results were benchmarked with our published results from previous years. Methods All patients sustaining penetrating arterial injuries to the limbs admitted to the Chris Hani Baragwanath Academic Hospital during an 18- month period ending in September 2011 were included in this study. Axillary, brachial and femoral artery injuries were operated on by the trauma surgeons as in the past. All popliteal artery injuries were operated on by the vascular surgeons (new). Results There were a total of 113 patients with 116 injuries, as some patients had multiple vascular injuries: 10 axillary, 47 brachial, 34 femoral and 25 popliteal artery injuries. Outcome of axillary, brachial and femoral artery injury repair were excellent and not significantly different from our previous reported experience. Injury to the popliteal artery showed a diminished re-exploration rate from 34% down to 10% (p = 0,049) and a decrease of amputation rate from 16% to 11% which was statistically not significant (p = 0,8). Conclusion Penetrating arterial trauma to the axillary, brachial and femoral artery is followed by excellent results when operated by trauma surgeons. In the case of popliteal artery injury operated by the vascular surgeons, the results of this study do not show any statistically significant difference related to amputation rate from our previous reported studies when operated by trauma surgeons. Taking into consideration the diminished re

    Vibrios and other enteric pathogens can be found in wastewater effluents of a healthy population. We assessed the prevalence of three non-cholerae vibrios in wastewater effluents of 14 wastewater treatment plants (WWTP) in Chris Hani and Amathole district municipalities in the Eastern Cape Province of South Africa for a period of 12 months. With the exception of WWTP10 where presumptive vibrios were not detected in summer and spring, presumptive vibrios were detected in all seasons in other WWTP effluents. When a sample of 1,000 presumptive Vibrio isolates taken from across all sampling sites were subjected to molecular confirmation for Vibrio, 668 were confirmed to belong to the genus Vibrio, giving a prevalence rate of 66.8 %. Further, molecular characterisation of 300 confirmed Vibrio isolates revealed that 11.6 % (35) were Vibrio parahaemolyticus, 28.6 % (86) were Vibrio fluvialis and 28 % (84) were Vibrio vulnificus while 31.8 % (95) belonged to other Vibrio spp. not assayed for in this study. Antibiogram profiling of the three Vibrio species showed that V. parahaemolyticus was ≥50 % susceptible to 8 of the test antibiotics and ≥50 % resistant to only 5 of the 13 test antibiotics, while V. vulnificus showed a susceptibility profile of ≥50 % to 7 of the test antibiotics and a resistance profile of ≥50 % to 6 of the 13 test antibiotics. V. fluvialis showed ≥50 % resistance to 8 of the 13 antibiotics used while showing ≥50 % susceptibility to only 4 antibiotics used. All three Vibrio species were susceptible to gentamycin, cefuroxime, meropenem and imipenem. Multiple antibiotic resistance patterns were also evident especially against such antibiotics as tetracyclin, polymixin B, penicillin G, sulfamethazole and erythromycin against which all Vibrio species were resistant. These results indicate a significant threat to public health, more so in the Eastern Cape Province of South Africa which is characterised by widespread poverty, with more than a

    The California Integrated Seismic Network (CISN) is a consortium of federal, state and academic institutions engaged in earthquake monitoring in California. The CISN represents California as a designated region of the Advanced National Seismic System (ANSS). The CISN is governed by a Steering Committee representing institutions actively involved in earthquake monitoring in California (currently USGS, CDMG, UCB and Caltech) and the California OES. Current members of the CISN Steering Committee are Barbara Romanowicz (chair) and Lind Gee (both at UCB), David Oppenheimer and Mary-Lou Zoback (both at USGS/Menlo Park), Egill Hauksson and Robert Clayton (both at Caltech), Jim Davis and Tony Shakal (both at CDMG), Lucy Jones (vice-chair) and David Wald (both at USGS/Pasadena), Rich Eisner (OES) and Chris Poland (Degenkolb Engineers; head of the CISN Advisory Committee). A major goal of the CISN is to ensure a more uniform system for earthquake monitoring, through the improvement of seismic infrastructure in northern California and continued maintenance of the TriNet system in southern California. Another major goal is to integrate the earthquake monitoring and reporting efforts in California, utilizing compatible softrware and creating a single catalog. In particular, we will work to improve the robustness of statewide rapid notification and work with the California OES and other emergency responders to maximize the use and benefit of this real time seismic information. In the coming year, with new support from the State of California through the Office of Emergency Services, and from the ANSS program of the USGS, more than 50 new strong-motion stations will be installed, with a focus in the San Francisco Bay Area, in order to improve coverage for ShakeMap and 2 new broadband stations will be deployed in northern California to enhance earthquake reporting. CISN is also contributing to structural monitoring. The CISN is also focusing on data distribution and plans to

  20. Vesicles versus Tubes: Is Endoplasmic Reticulum-Golgi Transport in Plants Fundamentally Different from Other Eukaryotes?

    PubMed

    Robinson, David G; Brandizzi, Federica; Hawes, Chris; Nakano, Akihiko

    2015-06-01

    The endoplasmic reticulum (ER) is the gateway to the secretory pathway in all eukaryotic cells. Its products subsequently pass through the Golgi apparatus on the way to the cell surface (true secretion) or to the lytic compartment of the cell (vacuolar protein transport). In animal cells, the Golgi apparatus is present as a stationary larger order complex near the nucleus, and transport between the cortical ER and the Golgi complex occurs via an intermediate compartment which is transported on microtubules. By contrast, higher plant cells have discrete mobile Golgi stacks that move along the cortical ER, and the intermediate compartment is absent. Although many of the major molecular players involved in ER-Golgi trafficking in mammalian and yeast (Saccharomyces cerevisiae) cells have homologs in higher plants, the narrow interface (less than 500 nm) between the Golgi and the ER, together with the motility factor, makes the identification of the transport vectors responsible for bidirectional traffic between these two organelles much more difficult. Over the years, a controversy has arisen over the two major possibilities by which transfer can occur: through vesicles or direct tubular connections. In this article, four leading plant cell biologists attempted to resolve this issue. Unfortunately, their opinions are so divergent and often opposing that it was not possible to reach a consensus. Thus, we decided to let each tell his or her version individually. The review begins with an article by Federica Brandizzi that provides the necessary molecular background on coat protein complexes in relation to the so-called secretory units model for ER-Golgi transport in highly vacuolated plant cells. The second article, written by Chris Hawes, presents the evidence in favor of tubules. It is followed by an article from David Robinson defending the classical notion that transport occurs via vesicles. The last article, by Akihiko Nakano, introduces the reader to possible

  1. Acoustic Emission Patterns and the Transition to Ductility in Sub-Micron Scale Laboratory Earthquakes

    Ghaffari, H.; Xia, K.; Young, R.

    2013-12-01

    We report observation of a transition from the brittle to ductile regime in precursor events from different rock materials (Granite, Sandstone, Basalt, and Gypsum) and Polymers (PMMA, PTFE and CR-39). Acoustic emission patterns associated with sub-micron scale laboratory earthquakes are mapped into network parameter spaces (functional damage networks). The sub-classes hold nearly constant timescales, indicating dependency of the sub-phases on the mechanism governing the previous evolutionary phase, i.e., deformation and failure of asperities. Based on our findings, we propose that the signature of the non-linear elastic zone around a crack tip is mapped into the details of the evolutionary phases, supporting the formation of a strongly weak zone in the vicinity of crack tips. Moreover, we recognize sub-micron to micron ruptures with signatures of 'stiffening' in the deformation phase of acoustic-waveforms. We propose that the latter rupture fronts carry critical rupture extensions, including possible dislocations faster than the shear wave speed. Using 'template super-shear waveforms' and their network characteristics, we show that the acoustic emission signals are possible super-shear or intersonic events. Ref. [1] Ghaffari, H. O., and R. P.

    This breakout session is a traditional conference instrument used by the NASA industrial hygiene personnel as a method to convene personnel across the Agency with common interests. This particular session focused on two key topics, training systems and automation of industrial hygiene data. During the FY 98 NASA Occupational Health Benchmarking study, the training system under development by the U.S. Environmental Protection Agency (EPA) was deemed to represent a "best business practice." The EPA has invested extensively in the development of computer based training covering a broad range of safety, health and environmental topics. Currently, five compact disks have been developed covering the topics listed: Safety, Health and Environmental Management Training for Field Inspection Activities; EPA Basic Radiation Training Safety Course; The OSHA 600 Collateral Duty Safety and Health Course; and Key program topics in environmental compliance, health and safety. Mr. Chris Johnson presented an overview of the EPA compact disk-based training system and answered questions on its deployment and use across the EPA. This training system has also recently been broadly distributed across other Federal Agencies. The EPA training system is considered "public domain" and, as such, is available to NASA at no cost in its current form. Copies of the five CD set of training programs were distributed to each NASA Center represented in the breakout session. Mr. Brisbin requested that each NASA Center review the training materials and determine whether there is interest in using the materials as it is or requesting that EPA tailor the training modules to suit NASA's training program needs. The Safety, Health and Medical Services organization at Ames Research Center has completed automation of several key program areas. Mr. Patrick Hogan, Safety Program Manager for Ames Research Center, presented a demonstration of the automated systems, which are described by the following: (1) Safety

    2001-12-01

    Since 1997 government and industry in The Netherlands have been engaged in intensive policy discussions on how to design an emission trading program that would satisfy the Government's policy objectives within the national and international regulatory framework and accommodate industry's need for a flexible and cost-effective approach. Early on in the discussion the most promising solution was a rate-based approach, which dynamically allocated saleable emission credits based on a performance standard rate and actual energy used by facilities. All industrial facilities above a threshold of 20 MWth would be judged on their ability to meet this performance rate. Those "cleaner" than the standard can sell excess credits to others with an allocation that is less than their actual NOX emission. With some changes in law, such a design could be made to fit well into the national and EU legislative framework while at the same time uniquely meeting industry's requirement of flexibility toward economic growth and facility expansion. (An analysis of the legislative changes required will be given in a separate paper by Chris Dekkers.) However, the environmental outcome of such a system is not as certain as under an absolute emission cap. At the request of the Netherlands Ministry of Housing, Spatial Planning and the Environment (VROM), Automated Credit Exchange (ACE), in close cooperation with the working group of government and industry representatives introduced a number of features into the Dutch NOX program allowing full exploitation of market mechanisms while allowing intermediate adjustments in the performance standard rates. The design is geared toward meeting environmental targets without jeopardizing the trading market the program intends to create. The paper discusses the genesis of the two-tier credit system ACE helped to design, explains the differences between primary (fixed) and secondary (variable) credits, and outlines how the Dutch system is expected to

    2013-12-01

    Astronauts have taken over 1 million photographs of Earth. Many of them directly support science research by documenting ephemeral events or showing Earth changes over the 50 year history of astronaut photography. And yet, even more of them are simply beautiful images of our wonderful planet. Astronauts love to look at the Earth from this 370km high vantage point. And they're constantly taking pictures - typically over 500 pictures each day. 'Oh, look at that' - click! 'And that' - click! Then they share them with scientists, other astronauts, and the public - as a way to help other people experience this transformative view of home planet Earth. Astronaut Chris Hadfield had 1.2 million followers on his tweeter feed from orbit, through which he sent hundreds of photographs. The yellows and oranges of the Sahara; serene islands in the middle of the Pacific; looking out over the snow-covered Alps; the night lights of Paris; looking straight down into an erupting volcano. What drama, what story, what a remarkable way to learn about Earth from the perspective of science and art. Each of these 1.2 million pictures was taken by a human, an astronaut who felt this awe and respect for Earth, who melded this art and science and pressed the button at the decisive moment. This session features dozens of these photographs, each selected as an all-time favorite by the astronauts after they returned to Earth. We will present the photos, as well as the astronauts' commentary, and an over-arching analysis of insights gained from the orbital perspective. We also will demonstrate the Windows on Earth software that the astronauts use on-orbit to plan their photographic opportunities and identify specific targets and features of interest, while orbiting at 17,000 mph. Finally, we will provide links to web-based resources for the public to get access to this entire archive of Earth photographs, so that they can pick their own favorites, download them, and explore creative ways to

  5. WARPED DISK MAY INDICATE PRESENCE OF PLANET AROUND THE STAR BETA PICTORIS

    NASA Technical Reports Server (NTRS)

    2002-01-01

    This image from NASA's Hubble Space Telescope shows for the first time the inner region of a 200-billion mile diameter dust disk around the star Beta Pictoris. This region has long been hidden from ground-based telescopes because of the glare from the central star. The disk is slightly warped. If the warp were there when the star formed, it would long since have flattened out, unless it is produced and maintained by the gravitational pull of a planet. The suspected planet would dwell inside a five-billion mile diameter clear zone inside the inner edge of the disk. Top This is a visible light image of the disk, which appears spindle-like because it is tilted nearly edge-on to our view. The disk is made up of microscopic dust grains of ices and silicate particles, and shines by reflected light from the star. This image indicates that the central clearing is occupied by one or more planets which agglomerated out of the disk and then swept out smaller particles. The bright star, which lies at the center of the disk, is blocked out in this image. Bottom False-color is applied through image processing to accentuate details in the disk structure. Hubble reveals that the pink-white inner edge of the disk is slightly tilted from the plane of the outer disk (red-yellow-green) as identified by a dotted line. A simple explanation is that a large planet is pulling on the disk. It is not possible to see the planet directly because it is close to the star, and perhaps a billion-times fainter. This image was taken with the Wide Field Planetary Camera 2 in January 1995. The star is located 50 light-years away in the southern constellation Pictor (Painter's Easel). Beta Pictoris is a main sequence star, slightly hotter than our Sun. Credit: Chris Burrows, Space Telescope Science Institute (STScI) the European Space Agency (ESA), J.

    The hydrogen molecule as the most abundant neutral molecule in the universe is an important object of studies in different areas of science, especially astrophysics. The precision spectroscopy of the hydrogen molecule is particularly useful to verify the quantum electrodynamics theory (QED) in a molecular system. The electric quadrupole transitions of the second overtone of H_2 have been recorded with a high precision cavity ring-down spectrometer. A total of eight lines including the extremely weak S3(5) line in the 784-852 nm range have been observed. The line positions have been determined to an accuracy of 3 × 10-4 cm-1 and the line intensities were determined with a relative accuracy of about 1%. The deviations between the experimental and theoretical frequencies are less than 5 × 10-4 cm-1, which is much smaller than the claimed theoretical uncertainty of 0.0025cm-1. The data from this experiment along with other high-quality H_2 spectra have also been analyzed by the Hartmann-Tran profile as a test case for incorporating parametrization of this profile in the HITRAN database. It was incorporated in the new relational structure of the HITRAN database (www.hitran.org) and into the HITRAN Application Programming Interface (HAPI) for the case of H_2 spectra.

    2001-12-01

    Since 1997 government and industry in The Netherlands have been engaged in intensive policy discussions on how to design an emission trading program that would satisfy the Government's policy objectives within the national and international regulatory framework and accommodate industry's need for a flexible and cost-effective approach. Early on in the discussion the most promising solution was a rate-based approach, which dynamically allocated saleable emission credits based on a performance standard rate and actual energy used by facilities. All industrial facilities above a threshold of 20 MWth would be judged on their ability to meet this performance rate. Those "cleaner" than the standard can sell excess credits to others with an allocation that is less than their actual NOX emission. With some changes in law, such a design could be made to fit well into the national and EU legislative framework while at the same time uniquely meeting industry's requirement of flexibility toward economic growth and facility expansion. (An analysis of the legislative changes required will be given in a separate paper by Chris Dekkers.) However, the environmental outcome of such a system is not as certain as under an absolute emission cap. At the request of the Netherlands Ministry of Housing, Spatial Planning and the Environment (VROM), Automated Credit Exchange (ACE), in close cooperation with the working group of government and industry representatives introduced a number of features into the Dutch NOX program allowing full exploitation of market mechanisms while allowing intermediate adjustments in the performance standard rates. The design is geared toward meeting environmental targets without jeopardizing the trading market the program intends to create. The paper discusses the genesis of the two-tier credit system ACE helped to design, explains the differences between primary (fixed) and secondary (variable) credits, and outlines how the Dutch system is expected to

    The English grain aphid, Sitobion avenae, is a major pest species of wheat crops; however, certain varieties may have stronger resistance to infestation than others. Here, we investigated 3 classical resistance mechanisms (antixenosis, antibiosis, and tolerance) by 14 wheat varieties/lines to S. avenae under laboratory and field conditions. Under laboratory conditions, alatae given the choice between 2 wheat varieties, strongly discriminated against certain varieties. Specifically, the ‘Amigo’ variety had the lowest palatability to S. avenae alatae of all varieties. ‘Tm’ (Triticum monococcum), ‘Astron,’ ‘Xanthus,’ ‘Ww2730,’ and ‘Batis’ varieties also had lower palatability than other varieties. Thus, these accessions may use antibiosis as the resistant mechanism. In contrast, under field conditions, there were no significant differences in the number of alatae detected on the 14 wheat varieties. One synthetic line (98-10-30, a cross between of Triticum aestivum (var. Chris) and Triticum turgidum (var. durum) hybridization) had low aphid numbers but high yield loss, indicating that it has high antibiosis, but poor tolerance. In comparison, ‘Amigo,’ ‘Xiaoyan22,’ and some ‘186Tm’ samples had high aphid numbers but low yield loss rates, indicating they have low antibiosis, but good tolerance. Aphid population size and wheat yield loss rates greatly varied in different fields and years for ‘98-10-35,’ ‘Xiaoyan22,’ ‘Tp,’ ‘Tam200,’ ‘PI high,’ and other ‘186Tm’ samples, which were hybrid offspring of T. aestivum and wheat related species. Thus, these germplasm should be considered for use in future studies. Overall, S. avenae is best adapted to ‘Xinong1376,’ because it was the most palatable variety, with the greatest yield loss rates of all 14 wheat varieties. However, individual varieties/lines influenced aphid populations differently in different years. Therefore, we strongly recommend a combination of

In recent years, it has become necessary to factor in the effects of a changing climate as well. There has also been a growing appreciation of the linkage between food security and water availability. In 2009, Famine Early Warning Systems Network (FEWS NET) science partners began developing land surface modeling (LSM) applications to address these needs. With support from the NASA Applied Sciences Program, an instance of the Land Information System (LIS) was developed to specifically support FEWS NET. A simple crop water balance model (GeoWRSI) traditionally used by FEWS NET took its place alongside the Noah land surface model and the latest version of the Variable Infiltration Capacity (VIC) model, and LIS data readers were developed for FEWS NET precipitation forcings (NOAA's RFE and USGS/UCSB's CHIRPS). The resulting system was successfully used to monitor and project soil moisture conditions in the Horn of Africa, foretelling poor crop outcomes in the OND 2013 and MAM 2014 seasons. In parallel, NOAA created another instance of LIS to monitor snow water resources in Afghanistan, which are an early indicator of water availability for irrigation and crop production. These successes have been followed by investment in LSM implementations to track and project water availability in Sub-Saharan Africa and Yemen, work that is now underway. Adoption of

    VOGRIPA originated as part of the Global Risk Identification Programme (GRIP) that is being co-ordinated from the Earth Institute of Columbia University under the auspices of the United Nations and World Bank. GRIP is a five-year programme aiming at improving global knowledge about risk from natural hazards and is part of the international response to the catastrophic 2004 Asian tsunami. VOGRIPA is also a formal IAVCEI project. The objectives of VOGRIPA are to create a global database of volcanic activity, hazards and vulnerability information that can be analysed to identify locations at high risk from volcanism, gaps in knowledge about hazards and risk, and will allow scientists and disaster managers at specific locations to analyse risk within a global context of systematic information. It is this added scope of risk and vulnerability as well as hazard which sets VOGRIPA apart from most previous databases. The University of Bristol is the central coordinating centre for the project, which is an international partnership including the Smithsonian Institution, the Geological Survey of Japan, the Earth Observatory of Singapore (Chris Newhall), the British Geological Survey, the University of Buffalo (SUNY) and Munich Re. The partnership is intended to grow and any individuals or institutions who are able to contribute resources to VOGRIPA objectives are welcome to participate. Work has already begun (funded principally by Munich Re) on populating a database of large magnitude explosive eruptions reaching back to the Quaternary, with extreme-value statistics being used to evaluate the magnitude-frequency relationship of such events, and also an assessment of how the quality of records affect the results. The following 4 years of funding from the European Research Council for VOGRIPA will be used to establish further international collaborations in order to develop different aspects of the database, with the data being accessible online once it is sufficiently

    The revised SWIRE photometric redshift catalogues for the Lockman, EN1, EN2 and XMM-LSS areas (plus original catalogues for ES1, CDFS, VVDS and SXDS areas). There are 1009607 lines of data (EN1: 204421, EN2: 116195, Lock: 217461, XMM-LSS: 280478, CDFS: 149766, ES1: 41757) The methodology is based on Rowan-Robinson et al. (2008MNRAS.386..697R). The main change here is the incorporation of SDSS and UKIDSS data into the solution. The details of how this was done will be reported in Rowan-Robinson et al. (2013MNRAS.428.1958R) but the main features are: (1) WFC data treated as in RR08 (Cat. II/290), but revised WFS data of Gonzalez-Solares et al. (2011MNRAS.416..927G) used for EN1, EN2, Lockman. New Megacam data used for XMM-LSS. (2) SDSS model magnitudes used, aperture corrected by forcing r-band magnitude to be same as r-WFC. (3) 2MASS point-source magnitudes used if available, aperture corrected by using a multiple (0.8) of the WFC r-band aperture correction. If not, UKIDSS point-source magnitudes used, aperture corrected by using a multiple (1.1) of the WFC r-band aperture correction. (4) IRAC fluxes are aperture corrected as in Rowan-Robinson et al. (2008MNRAS.386..697R). (5) Lockman data are from 2008 reduction, with requirement that S(3.6)>7.5μJy. (6) SXDS sources with new Megacam data are reanalyzed using Subaru+Megacam data (40553 sources). The remainder (13655 sources) are from the 2008 reduction. New spectroscopic redshifts from Chris Simpson (2012 in prep) are incorporated. (7) For quasars we have added AGN dust torus templates to our 3 QSO templates, with amplitudes corresponding to Ltor/Lopt = 0, 0.2, 0.4, 0.6, 0.8, 1.0, and used 1.25-8.0μm data in the redshift solution. This improves the outlier rejection (see the paper for details). (8) Although the redshifts have not changed greatly from the 2008 catalogue, it was necessary to rerun the infrared template fitting in order to register the correct infrared luminosity, ir sed type and derived quantities

    This internship assignment for spring 2014 was at John F. Kennedy Space Center (KSC), in NASAs Engineering and Technology (NE) group in support of the Control and Data Systems Division (NE-C) within the Systems Hardware Engineering Branch. (NEC-4) The primary focus was in system integration and benchmarking utilizing two separate computer software products. The first half of this 2014 internship is spent in assisting NE-C4s Electronics and Embedded Systems Engineer, Kelvin Ruiz and fellow intern Scott Ditto with the evaluation of a newly piece of software, called G2. Its developed by the Gensym Corporation and introduced to the group as a tool used in monitoring launch environments. All fellow interns and employees of the G2 group have been working together in order to better understand the significance of the G2 application and how KSC can benefit from its capabilities. The second stage of this Spring project is to assist with an ongoing integration of a benchmarking tool, developed by a group of engineers from a Canadian based organization known as TSO Logic. Guided by NE-C4s Computer Engineer, Allen Villorin, NASA 2014 interns put forth great effort in helping to integrate TSOs software into the Spaceport Processing Systems Development Laboratory (SPSDL) for further testing and evaluating. The TSO Logic group claims that their software is designed for, monitoring and reducing energy consumption at in-house server farms and large data centers, allows data centers to control the power state of servers, without impacting availability or performance and without changes to infrastructure and the focus of the assignment is to test this theory. TSOs Aaron Rallo Founder and CEO, and Chris Tivel CTO, both came to KSC to assist with the installation of their software in the SPSDL laboratory. TSOs software is installed onto 24 individual workstations running three different operating systems. The workstations were divided into three groups of 8 with each group having its

    This document contains the final reports from the five panels that comprised a Workshop held to explore future directions, scientific impacts and technological connections of research in Atomic, Molecular and Optical Physics. This workshop was sponsored by the Department of Energy, Office of Basic Energy Sciences, Chemical Sciences Division and was held at the Westfields International Conference Center in Chantilly, Virginia on September 21-24, 1997. The workshop was chaired by Lloyd Armstrong, Jr., University of Southern California and the five panels focused on the following topics: Panel A: Interactions of Atoms and Molecules with Photons - Low Field Daniel Kleppner (Massachusetts Institute of Technology), chair Panel B: Interactions of Atoms and Molecules with Photons - High Field Phil Bucksbaum (University of Michigan), chair Panel C: Surface Interactions with Photons, Electrons, Ions, Atoms and Molecules J. Wayne Rabalais (University of Houston), chair Panel D: Theory of Structure and Dynamics Chris Greene (University of Colorado), chair Panel E: Nano- and Mesocopic Structures Paul Alivisatos (Lawrence Berkeley National Laboratory), chair The choice of focus areas reflects areas of significant interest to DOE/BES but is clearly not intended to span all fields encompassed by the designation of atomic, molecular and optical physics, nor even all areas that would be considered for review and funding under DOE’s AMOP program. In a similar vein, not all research that might be suggested under these topics in this report would be appropriate for consideration by DOE’s AMOP program. The workshop format included overview presentations from each of the panel chairs, followed by an intensive series of panel discussion sessions held over a two-day period. The panels were comprised of scientists from the U. S. and abroad, many of whom are not supported by DOE’s AMOP Program.

  16. Aggregation and disaggregation of radar rainfall rates

    NASA Astrophysics Data System (ADS)

    Krebsbach, K.; Friederichs, P.

    2012-12-01

    Spatially distributed, high-resolution precipitation rates are key ingredients for modeling soil-vegetation processes, water and solute transports in mesoscale catchments, and for short-range weather prediction. The ultimate goal of our study is to develop a space-time, multilevel statistical model that merges rain radar measurements with other observations of precipitation. This is a challenging task since it aims at combining data sources with a variety of error structures, and temporal resolutions. E.g., in-situ measurements are quite accurate, but available only at sparse and irregularly distributed locations, whereas remote measurements cover complete areas but suffer from spatially and temporally inhomogeneous systematic errors. The first step towards such a space-time precipitation model is to develop a statistical model for precipitation based on radar measurements. Precipitation rates over a region of about 230× 230 km2 are provided by a composite of the two polarimetric X-band radars in Germany. The two radars are located in a distance of about 60 km in Bonn and Jülich, respectively. For the statistical model formulation we use a Gaussian Markov random field as underlying process. A Markov random field is a suitable model to account for spatial dependencies if the neighborhood can be reduced to a small region without losing information. This makes large data problems computationally feasible, since the neighborhood structure is given by a sparse precision matrix. Markov random fields are closely related to a graphical models. In processing the unadjusted radar rainfall rates, we follow D. Allcroft and C. Glasbey (2003)footnote{⪉bel{foot:1}David Allcroft and Chris Glasbey (2003). A latent Gaussian Markov Random Field model for spatiotemporal rainfall disaggregationJournal of the Royal Statistical Society: Series C (Applied Statistics), 52:487-498}. We start with a transformation of the precipitation rates to a truncated Gaussian distribution. The

    The ideas of systems pervade the Next Generation Science Standards, and well they should. The title of this abstract, paraphrased from commentator Chris Hayes, bluntly summarizes what should be central to the design of curriculum and instruction in the era of climate change and NGSS. It reflects a systems perspective, highlighting that the relationship between and among scientific topics are as important as the topics themselves. The centrality of systems and of human impacts within systems is highlighted by the fact that within the NGSS, the most connected Disciplinary Core Idea is Earth and Space Sciences - 3: Earth and Human Activity. 'ESS3' appears 457 times and on more than a third of the pages in the pdf of all the performance expectations. The lion's share of these appearances are in the connections boxes below the performance indicators, showing the connections -- the relationships within the Earth system -- of this topic to a multitude of expectations. Deep understandings of climate and climate change require understandings relationships between the atmosphere and human activity, and especially the impacts of energy use. As energy is needed for essentially everything we do, this is a big deal. Yet, in the typical high school science programs today, energy and its relation to climate is not prominent. NGSS has the potential to change that. The Crosscutting Concepts clearly reflect a systems approach, with four of the seven including the word 'system' within their one sentence description. This presentation will address systems in NGSS generally and use the examples from our changing energy system, to highlight ways to address climate and energy in multiple courses at different grade levels. Energy use varies across time and space, and the study of energy ties directly to all of Crosscutting Concepts. We will consider the map, showing aspects of the geography of energy, and historical energy transitions, such as the move from dependence of wood for fuel to

  2. Vesicles versus Tubes: Is Endoplasmic Reticulum-Golgi Transport in Plants Fundamentally Different from Other Eukaryotes?1

    The endoplasmic reticulum (ER) is the gateway to the secretory pathway in all eukaryotic cells. Its products subsequently pass through the Golgi apparatus on the way to the cell surface (true secretion) or to the lytic compartment of the cell (vacuolar protein transport). In animal cells, the Golgi apparatus is present as a stationary larger order complex near the nucleus, and transport between the cortical ER and the Golgi complex occurs via an intermediate compartment which is transported on microtubules. By contrast, higher plant cells have discrete mobile Golgi stacks that move along the cortical ER, and the intermediate compartment is absent. Although many of the major molecular players involved in ER-Golgi trafficking in mammalian and yeast (Saccharomyces cerevisiae) cells have homologs in higher plants, the narrow interface (less than 500 nm) between the Golgi and the ER, together with the motility factor, makes the identification of the transport vectors responsible for bidirectional traffic between these two organelles much more difficult. Over the years, a controversy has arisen over the two major possibilities by which transfer can occur: through vesicles or direct tubular connections. In this article, four leading plant cell biologists attempted to resolve this issue. Unfortunately, their opinions are so divergent and often opposing that it was not possible to reach a consensus. Thus, we decided to let each tell his or her version individually. The review begins with an article by Federica Brandizzi that provides the necessary molecular background on coat protein complexes in relation to the so-called secretory units model for ER-Golgi transport in highly vacuolated plant cells. The second article, written by Chris Hawes, presents the evidence in favor of tubules. It is followed by an article from David Robinson defending the classical notion that transport occurs via vesicles. The last article, by Akihiko Nakano, introduces the reader to possible

    The Petroleum Technology Transfer Council (PTTC) is a unique not-for-profit network that focuses on transferring Exploration and Production (E&P) technology to the domestic oil and natural gas producing industry. PTTC connects producers, technology providers and innovators, academia, research and development (R&D) consortiums and governments. Local affordable workshops delivered by Regional Lead Organizations (RLOs), which are typically a university or geological survey, are a primary tool. PTTC also maintains a website network, issues a national newsletter, provides a column in a major trade publication, and exhibits at major industry events. It also encourages industry to ask technology-related questions, striving to find relevant answers that will save questioners significant time. Working since late 1993, the PTTC network has a proven track record of providing industry with technology insights they can apply. Volunteers at the regional and national level provide key guidance regarding where to focus technical effort and help connect PTTC with industry. At historical funding levels, PTTC had been able to hold well more than 100 workshops per year, drawing 6,000+ attendees. As funding decreased in the early 2000s, the level of activity decreased and PTTC sought a merger with the American Association of Petroleum Geologists (AAPG), becoming an AAPG-managed organization at the start of FY08. This relationship with AAPG was terminated by mutual consent in May 2011 and PTTC once again operates independently. Chris Hall, California continued to serve as Chairman of the Board of Directors until December 2013. At the time PTTC reorganized into a RLO led organization with Mary Carr and Jeremy Viscomi as co-Executive Directors. Jerry Anderson became the Chairman of the PTTC Board of Directors and Chris Hall continues to serve on the Board. Workshop activity stabilized at 55-65 workshops per year averaging 3,100 attendees. FY14 represented the fifth year in a multi

    This report summarizes a meeting of geologists, marine sedimentologists, geophysicists, and seismologists that was held on November 18–19, 2010 at Oregon State University in Corvallis, Oregon. The overall goal of the meeting was to evaluate observations of turbidite deposits to provide constraints on the recurrence time and rupture extent of great Cascadia subduction zone (CSZ) earthquakes for the next update of the U.S. national seismic hazard maps (NSHM). The meeting was convened at Oregon State University because this is the major center for collecting and evaluating turbidite evidence of great Cascadia earthquakes by Chris Goldfinger and his colleagues. We especially wanted the participants to see some of the numerous deep sea cores this group has collected that contain the turbidite deposits. Great earthquakes on the CSZ pose a major tsunami, ground-shaking, and ground-failure hazard to the Pacific Northwest. Figure 1 shows a map of the Pacific Northwest with a model for the rupture zone of a moment magnitude Mw 9.0 earthquake on the CSZ and the ground shaking intensity (in ShakeMap format) expected from such an earthquake, based on empirical ground-motion prediction equations. The damaging effects of such an earthquake would occur over a wide swath of the Pacific Northwest and an accompanying tsunami would likely cause devastation along the Pacifc Northwest coast and possibly cause damage and loss of life in other areas of the Pacific. A magnitude 8 earthquake on the CSZ would cause damaging ground shaking and ground failure over a substantial area and could also generate a destructive tsunami. The recent tragic occurrence of the 2011 Mw 9.0 Tohoku-Oki, Japan, earthquake highlights the importance of having accurate estimates of the recurrence times and magnitudes of great earthquakes on subduction zones. For the U.S. national seismic hazard maps, estimating the hazard from the Cascadia subduction zone has been based on coastal paleoseismic evidence of great

    capabilities of current instruments -- the team used their intensity-mapping technique to accumulate the radio waves emitted by the hydrogen gas in large volumes of space including many galaxies. "Since the early part of the 20th Century, astronomers have traced the expansion of the Universe by observing galaxies. Our new technique allows us to skip the galaxy-detection step and gather radio emissions from a thousand galaxies at a time, as well as all the dimly-glowing material between them," said Jeffrey Peterson, of Carnegie Mellon University. The astronomers also developed new techniques that removed both man-made radio interference and radio emission caused by more-nearby astronomical sources, leaving only the extremely faint radio waves coming from the very distant hydrogen gas. The result was a map of part of the "cosmic web" that correlated neatly with the structure shown by the earlier optical study. The team first proposed their intensity-mapping technique in 2008, and their GBT observations were the first test of the idea. "These observations detected more hydrogen gas than all the previously-detected hydrogen in the Universe, and at distances ten times farther than any radio wave-emitting hydrogen seen before," said Ue-Li Pen of the University of Toronto. "This is a demonstration of an important technique that has great promise for future studies of the evolution of large-scale structure in the Universe," said National Radio Astronomy Observatory Chief Scientist Chris Carilli, who was not part of the research team. In addition to Chang, Peterson, and Pen, the research team included Kevin Bandura of Carnegie Mellon University. The scientists reported their work in the July 22 issue of the scientific journal Nature.

In the 'top-down' approach, overall carbon fluxes are determined by combining remote measurements of carbon dioxide concentrations with complex atmospheric transport models, and these emissions measurements are compared to 'bottom-up' predictions based on detailed inventories of the sources and sinks of carbon, both anthropogenic and biogenic in nature. This approach, which has proven to be effective at continental scales, becomes challenging to implement at urban scales, due to poorly understood atmospheric transport models and high variability of the emissions sources in space (e.g., factories, highways, green spaces) and time (rush hours, factory shifts and shutdowns, and diurnal and seasonal variation in residential energy use). New measurement and analysis techniques are required to make sense of the carbon dioxide signal in cities. Here we present detailed, high spatial- and temporal- resolution greenhouse gas measurements made by multiple Picarro-CRDS analyzers in Silicon Valley in California. Real-time carbon dioxide data from a 12-month period are combined with real-time carbon monoxide, methane, acetylene, and carbon-13 measurements to partition the observed carbon dioxide concentrations between different anthropogenic sectors (e.g., transport, residential) and biogenic sources. Real-time wind rose data are also combined with real-time methane data to help identify the direction of local emissions of methane

    the afternoon outing to Arundel Castle and dinner in the evening at Wiston House, a mansion of Tudor origin near Steyning, West Sussex. So a short audience-participation seminar was held in the conference room of the manor, covering the history of dislocations and the history of the conference series. We were also able to extend the appreciation of the life of Prof. Yuri Ossipyan (15 Feb 1931 - 10 Sep 2008) briefly given at EDS2008. EDS2010 continued the drive into graphene-based materials with a session devoted to them, and it gave immense pleasure to many of us who were his former students to dedicate a session to the work of Professor R Jones. We are grateful to his present and former co-workers who came and presented an impressive perspective on their work with him and a vision of a vigorous future for him in his retirement and for AIMPRO, the current Density Functional Theory code that derives from the one he established with his former student, Dr Patrick Briddon. For EDS2010 we made two minor modifications to the appearance of the conference: a central webpage www.eds-conferences.org, ably managed by our webmaster, Dr Gemma Haffenden, and a Facebook page, "EDS conference series", which Dr Amy Gandy runs enthusiastically. Amongst other things the conference photographs appear here. "I like this". In fact, currently 22 FB-ers "like this" and I am sure it will grow. Finally, it is a pleasure to acknowledge the significant contributions of Co-Chair, Prof. Marek Skowronski, Conference Manager, Dr Christopher Latham, and the editors of this volume, Drs Jon Goss and Chris Ewels, who in turn wish to thank Dr Alexis Vlandas for his help proof reading the articles. We all wish the best of luck to Prof. Philomela Khomninou and her team in the organisation of EDS2012.

    Radiative Transfer Models (RTM) provided the platform for synergistically exploiting the specific and independent information dimensions obtained by the two earth observation systems. The proposed research relies on a radiative transfer model adapted to imaging spectrometer data (GeoSAIL) and a LiDAR waveform model based on the same 3D canopy structure. Both the GeoSAIL and LiDAR waveform models have already been employed and validated to retrieve forest properties from Imaging Spectrometer and LiDAR data separately. As these models are based on the same basic physical concept and share common input parameters an interface between these models can be established, which allows for the generation of a Look Up Table (LUT) consisting of the simulated signatures of the Imaging Spectrometer and LiDAR as a function of a common forest stand parameterization. In the presented approach, the specific information content inherent to the observations of the respective sensor was not only able to complement the canopy characterization, but also helped to solve the ill-posed problem of the RTM inversion. A comprehensive data set including EO and field data has been available for the validation of the proposed earth observation concept over a mixed hardwood and softwood forest part of the Northern Experimental Forest (NEF), Howland, Maine (45°15'N, 68°45'W). The Laser Vegetation Imaging Sensor (LVIS) acquired full waveform data over the site in the summer of 2003 as part of a NASA Terrestrial Ecology Program aircraft campaign. Further the Compact High Resolution Imaging Spectrometer (CHRIS) on the ESA platform Proba data acquired imaging spectrometer data in 2006-08. As reference data every tree in a 200m by 150m area was measured for its location, dbh, and species in 1990, and was re-measured in 2003-2004 and 2006. The field data has been complemented by hemispherical photographs characterizing the canopy structure as well as with field spectrometer measurements of the optical

    through Lower Oligocene). These sedimentary bedrock materials are locally intruded by Oligocene diabase and capped by Oligocene through Miocene basalt of the Mindego Formation (Brabb, 1980; Cole and others, 1994). Within the active landslide, as documented from multiple borings by Cole and others (1994), deeply weathered mudstone and sandstone of the San Lorenzo Formation extends to a depth of about 10 to 13 m, where the active shear zone is located. Beneath this, within the deeper prehistoric landslide, mudstone extends to a depth of about 24 to 32 m and is underlain by strong diabase bedrock. The basal rupture surface of the prehistoric landslide is located near the mudstone/diabase contact (Cole and others, 1994). The historically active section of the Weeks Creek landslide, which is crossed by the La Honda road (California Highway 84, fig. 1), was first noticed to partially move during the great 1906 San Francisco earthquake (Lawson, 1908). It has moved repeatedly over the ensuing years but generally only during wet rainy seasons. For some of these active years, ground cracks and lateral displacements were recorded by local residents Walter Jodicke and Chris Pearson, as well as by U.S. Geological Survey (USGS) personnel. In spring 2006, fresh ground cracks were noted in parts of the prehistoric, previously inactive section of the landslide. In this report, we present daily rainfall measurements from 1973 through 2006 obtained at the landslide site and summarize available observations of slope movement over that period. In addition, we present more detailed observations of rainfall, ground-water pressure, and slope movement for three water years spanning the period 1981-1984. We conclude with some preliminary observations about rainfall and slope movement at this site.

    mildew susceptibility in the pmr5 mutant background. These suppressor loci, TBR and RWA2, both appear to influence the degree of acetylation of cell wall polysaccharides, although in different ways (unpublished, and publication 4 below). Once the specific cell wall change is identified in pmr5 cell walls, we will be able to characterize this cell wall fragment in tbr, rwa2 and pmr5 tbr and pmr5 rwa2 mutants for insights into what kinds of cell wall changes impact disease resistance. The smaller stature of the pmr5 mutants is reversed in the pmr5 tbr and pmr5 rwa2 double mutants, suggesting that analyses of these lines will also provide insights into cell expansion and growth. We collaborated with H. Scheller (DOE - Joint Bioenergy Institute, Emeryville, CA) on the rwa2 suppressors of pmr5 and the role of RWA2 in disease resistance (see publication 4). We also collaborated with Berkeley colleagues Marcus Pauly and Chris Somerville, who work on other members of the 45-member DUF231/TBR family, Mary Wildermuth (University of California, Berkeley, CA) and Mike Hahn (Complex Carbohydrate Research Center, Athens, GA).

    of sustainable energy provides an opportunity for expanded involvement with industrial research. We were privileged to recruit several outstanding new leaders at the APS. Linda Young, from Argonne's Chemical Sciences Division, became the new Director of the X-ray Science Division (XSD). Chris Jacobsen (from Stony Brook University) has been added to Linda's team as an XSD Associate Division Director, joining George Srajer. Alexander (Sasha) Zholents (formerly of Berkeley Lab) became Director of the Accelerator Systems Division. Sasha is the inventor of the short-pulse x-ray scheme that we plan to implement in the APS-U to obtain very high average brightness, broadband, 1-ps x-ray pulses. Walter Lowe (formerly of Howard University) has taken a new position as senior advisor for outreach and development of the user community. Walter's role is to increase the diversity of the user community (with diversity read broadly to include users, institutions, and technical disciplines that are underrepresented at APS). Walter is also leading an effort to increase access for industrial users. I am confident that we have in place a great team to help our users and the APS take fullest advantage of the APS-U opportunity. In planning with users for the proposed APS-U, we focused on the need to study 'real materials under real conditions in real time' on spatial and temporal scales unavailable today. Only by studying materials as they are made-or as they perform-in difficult environments can we solve the grand challenge of higher-performance, sustainable materials for energy and health. The proposed APS-U will improve the brightness of penetrating x-rays produced by the APS over 100 times, and support our efforts in developing state-of-the-art instruments to address these challenges.

    mil to as low as -60 % (potentially comparable to that which accompanies the biosynthesis of organic matter). We need to understand what kind of fractionations are observed with reactions under the non-reducing or mildly reducing conditions now thought to be present on the early Earth. While nitrogen is receiving increased attention as a tool for these kinds of analyses, almost nothing is known about the isotope fractionation that one would expect for abiotic sources of fixed/reduced nitrogen. This project will measure the fixation from a series of abiotic reactions that may have been present on the early Earth (and other terrestrial planets) and produced organic material that could have ended up in the rock record. The work will look at a number of reactions, under a non- reducing, or mildly reducing, atmosphere, covering sources of prebiotic organic C & N from shock heating, to photochemistry, to hydrothermal reactions. Some reactions that we plan to study are; Shock heating of a non-reducing atmosphere to produce CO and NO (in collaboration with Chris McKay), formation of formaldehyde (and related compounds) from COY the formation of ammonia from nitrogen oxides (ultimately from NO) by ferrous iron reduction, and the hydrothermal synthesis of compounds including the hydrocarboxylation/hydrocarbonylation reaction (in collaboration with George Cody), reactions of oxalate to form hydrocarbons and other oxygenated compounds and the formation of lipids from oxalic/formic acid (in collaboration with Tom McCollom), and reactions of carbon monoxide & carbon dioxide with N2, ammonia or nitritehitrate to form hydrogen cyanide, nitriles, ammonia/amines and nitrous

    sounder data was the primary bathymetric mapping tool. As a result it was built on a remarkably simplistic view of the seafloor that has been completely overturned by the swath bathymetric data collected over the last two decades. This process must then somehow reconcile the great diversity of seafloor structure and composition that has been recognized with the simplistic language of the treaty itself. While this process relies on scientific data, it is not hypothesis testing, where, by successive elimination of the unlikely we claim to find some "truth" as a residue. In this context the data are material for advocacy, to establish a positive case for each particular claim. If the science is something like art, making a beautiful object is like seeking the unique, optimal hypothesis, then this instrumental advocacy is something more like engineering. The data are a means to achieve a particular objective, in the typical situation, the goal is to maximize the claimed area. Chris Carleton has referred to "the technical expert and his political masters"; a relationship that this presentation will address and discuss some of the potential uses of Article 76 data in the arctic and the application of Article 76 by the circum-arctic states to the Arctic Ocean.

    density differences together with field measurements of pipe radii and spacing. Rapid solidification of the gabbro along its lower contact accompanied by an increase in viscosity slowed down the ascent of the pipes and ultimately arrested them in their present state. Petrographic analyses of samples taken across the gabbro-diorite contacts and pipe-gabbro contacts indicate significant differences in the occurrence and abundance of hydrous phases, notably biotite and hornblende, between the chilled gabbro contacts and bulk of the gabbro, the underlying diorite, and the pipes. SEM-EDS analyses also reveal changes in mineral compositions within a few mm of the pipe-gabbro and gabbro-diorite contacts (e.g. drop in plagioclase An content in chilled gabbro surrounding pipes). These observations suggest transfer of water from the diorite and/or pipes into anhydrous gabbro as well as physical transfer of crystals across these boundaries. Quantifying the mineral and chemical differences along the pipe-gabbro and gabbro-diorite contacts in the context of the timescales of R-T instability and solidification reveal the in situ rates of physical and chemical exchange between these magmas.

    Satellite data from platforms with pointing capabilities (CHRIS/Proba, RapidEye) or from sensors with wide swath (AVHRR, MODIS, MERIS) is influenced by the bidirectional reflectance distribution function (BRDF). This effect can cause significant changes in the measured spectral surface reflectance depending on the solar illumination geometry and sensor viewing conditions. The Environmental Mapping and Analysis Program (EnMAP), a German hyperspectral mission with expected launch in 2016, will provide high spectral resolution observations with a ground sampling distance of 30 meters. Since the EnMAP sensor has pointing capabilities, both spectral and directional reflection characteristics need to be taken into account for the algorithms development for vegetation parameters. The 'hyperspectral method development for Arctic VEGetation biomes' (hy-Arc-VEG) project is part of the national preparation program for the EnMAP mission. Within the EnMAP projcect hy-Arc-VEG we developed a portable field spectro-goniometer, named ManTIS (Manual Transportable Instrument for Spherical BRDF observations), for the in-situ measurements of anisotropic effects of tundra surfaces (national and international patent pending - DE 102011117713.6). The goniometer was designed for field use in difficult as well as challenging terrain and climate. It is therefore of low weight, without electrical devices and weatherproof. It can be disassembled and packed into small boxes for transport. The current off-nadir viewing capacity is matched to the EnMAP sensor configuration (up to 30°). We carried out spectral field and goniometer measurements on the joint YAMAL 2011 expedition (RU-US-DE) organized by the Earth-Cryosphere Institute (ECI) in August 2011 on the Yamal Peninsula, northwestern Siberia, Russia. The field goniometer measurements (conducted under varying sun zenith angles) as well as field spectro-radiometrical measurements were carried out at the NASA Yamal Land Cover/Land Use Change

    filters capture the narrow lines from atomic transitions in oxygen and hydrogen; two wider filters detect green and near-infrared light. In the narrow-band filters, the V-shaped structure is very pronounced. This region, which is the projection of a three-dimensional cone extending from the nucleus to the galaxy's halo, contains gas that has been heated by radiation emitted by the accreting black hole. A 'counter-cone,' believed to be present, is obscured from view by dust in the galaxy's disk. Ultraviolet radiation emerging from the central source excites nearby gas causing it to glow. The excited gas is beamed into the oppositely directed cones like two giant searchlights. Located near the plane of our own Milky Way Galaxy, the Circinus galaxy is partially hidden by intervening dust along our line of sight. As a result, the galaxy went unnoticed until about 25 years ago. This Hubble image was taken on April 10, 1999 with the Wide Field Planetary Camera 2. The research team, led by Andrew S. Wilson of the University of Maryland, is using these visible light images along with near-infrared data to further understand the dynamics of this powerful galaxy. Credits: NASA, Andrew S.

    Dr. Sargent noted that evidence of other solar systems that might sustain life, particularly human life, is being sought. Protoplanetary (or debris) disks have been observed and are considered evidence that other solar systems exist or are being formed. Also observed is a wobble which is seen as evidence of circulation around a celestial body and gaps that are created by the potential planet. One indicator of life may be these rings or disks of debris around stars. Interferometers, which are telescopic devices that consist of multiple lenses, are being developed in order to better see celestial objects and what may be found around them. Other methods for improving celestial viewing capabilities are also under development. She spoke of particularly looking for wobble and gaps and debris disks where new planets are being formed in an effort to discover another planet that might sustain life as we know it. The next speaker, Dr. Chris McKay, is a planetary scientist at NASA Ames. He talked about the possibility of life on Mars or in some other solar system. He commented on the sameness of the origin of all life, and of the origin of, and the need for, oxygen and water. He believes that water originally came to Earth from comets. At least that is a viable possible source. Water might also have come to Earth via asteroids. Dr. McKay also postulates that there can be no water on Mars because Mars has no plate tectonic system, which he believes is an essential for recycling water. . Dr. Wes Huntress, NASA s Associate Administrator for Space Science, and Dr. Barbara Stone, also from NASA Headquarters, joined Drs. Cordova, Sargent and McKay in the question and answer period following the presentations. (Mr. Goldin was excused to keep an appointment with the President.) The discussion included the following statements and questions: The more missions that there are, the more technology is developed. We need to study our solar system to have something to which we can compare
