In other embodiments, a model relating hemoglobin concentration and infrared spectra to pH can be used. An apparatus according to the present invention can comprise an illumination system, adapted to supply radiation to a sample; a collection system, adapted to collect radiation expressed from the sample responsive to the incident radiation; and an analysis system, adapted to relate information about the incident radiation, the expressed radiation, and the hemoglobin concentration of the sample to pH.

  3. Mitochondrial DNA sequence evolution and phylogeny of the Atlantic Alcidae, including the extinct great auk (Pinguinus impennis). (United States)

    Moum, Truls; Arnason, Ulfur; Arnason, Einar


    The Atlantic auk assemblage includes four extant species, razorbill (Alca torda), dovekie (Alle alle), common murre (Uria aalge), and thick-billed murre (U. lomvia), and one recently extinct species, the flightless great auk (Pinguinus impennis). To determine the phylogenetic relationships among the species, a contiguous 4.2-kb region of the mitochondrial genome from the extant species was amplified using PCR. This region included one ribosomal RNA gene, four transfer RNA genes, two protein-coding genes, the control region, and intergenic spacers. Sets of PCR primers for amplifying the same region from great auk were designed from sequences of the extant species. The authenticity of the great auk sequence was ascertained by alternative amplifications, cloning, and separate analyses in an independent laboratory. Phylogenetic analyses of the entire assemblage, made possible by the great auk sequence, fully resolved the phylogenetic relationships and split it into two primary lineages, Uria versus Alle, Alca, and Pinguinus. A sister group relationship was identified between Alca and Pinguinus to the exclusion of ALLE: Phylogenetically, the flightless great auk originated late relative to other divergences within the assemblage. This suggests that three highly divergent species in terms of adaptive specializations, Alca, Alle, and Pinguinus, evolved from a single lineage in the Atlantic Ocean, in a process similar to the initial adaptive radiation of alcids in the Pacific Ocean.

    Poulsen, Niels Kjølstad; Damsgaard, Aage; Reinhold, Thim A.


    A new method which combines control theory and system identification techniques has been used to extract flutter derivatives from section model tests for the Great Belt East Bridge. Tests were conducted by exciting the section model simultaneously in vertical and torsional modes of vibration. Tests...... were primarily conducted in smooth flow for various ratios between vertical and torsional frequencies of vibration. Limited testing was also conducted in turbulent flow and for different angles of attack. The analysis technique described allowed extraction of seven aerodynamic derivatives including...... coupled motion derivatives from a simple set of tests.This paper describes the control theory and system identification approach used and discusses the limitations encountered. Results are compared with flutter derivatives obtained by other researchers. The method offers a reasonably robust technique...

  6. Laurentian Great Lakes Phytoplankton and Their Water Quality Characteristics, Including a Diatom-Based Model for Paleoreconstruction of Phosphorus (United States)

    Reavie, Euan D.; Heathcote, Adam J.; Shaw Chraïbi, Victoria L.


    Recent shifts in water quality and food web characteristics driven by anthropogenic impacts on the Laurentian Great Lakes warranted an examination of pelagic primary producers as tracers of environmental change. The distributions of the 263 common phytoplankton taxa were related to water quality variables to determine taxon-specific responses that may be useful in indicator models. A detailed checklist of taxa and their environmental optima are provided. Multivariate analyses indicated a strong relationship between total phosphorus (TP) and patterns in the diatom assemblages across the Great Lakes. Of the 118 common diatom taxa, 90 (76%) had a directional response along the TP gradient. We further evaluated a diatom-based transfer function for TP based on the weighted-average abundance of taxa, assuming unimodal distributions along the TP gradient. The r2 between observed and inferred TP in the training dataset was 0.79. Substantial spatial and environmental autocorrelation within the training set of samples justified the need for further model validation. A randomization procedure indicated that the actual transfer function consistently performed better than functions based on reshuffled environmental data. Further, TP was minimally confounded by other environmental variables, as indicated by the relatively large amount of unique variance in the diatoms explained by TP. We demonstrated the effectiveness of the transfer function by hindcasting TP concentrations using fossil diatom assemblages in a Lake Superior sediment core. Passive, multivariate analysis of the fossil samples against the training set indicated that phosphorus was a strong determinant of historical diatom assemblages, verifying that the transfer function was suited to reconstruct past TP in Lake Superior. Collectively, these results showed that phytoplankton coefficients for water quality can be robust indicators of Great Lakes pelagic condition. The diatom-based transfer function can be used in

  7. Experimental determination of linear optics including quadrupole rotations

    International Nuclear Information System (INIS)

    Safranek, J.


    The measured response matrix giving the change in orbit at beam position monitors (BPMs) with changes in steering magnet excitation can be used to accurately determine many important parameters in a storage ring. Using the NSLS X-Ray Ring measured response matrix we have determined the gradients in all 56 quadrupole magnets; the calibration of the steering magnets and BPMs; the rotational mis-alignments of the quadrupoles, steering magnets, and BPMs about the electron beam direction; the longitudinal magnetic centers of the orbit steering magnets; and the transverse mis-alignments of the sextupoles. Random orbit measurement error of the BPMs propagated to give 0.04% rms error in determination of individual quadrupole gradients and 0.4 mrad rms error in the determination of quadrupole rotational alignment. Small variations of a few parts in a thousand in the quadrupole gradients within an individual family were resolved. The improved understanding of the X-Ray Ring has enabled us to better control the electron beam size

  8. Determinants of prosocial behavior in included versus excluded contexts

    Esther eCuadrado


    Full Text Available Prosocial behavior is increasingly becoming necessary as more and more individuals experience exclusion. In this context it is important to understand the motivational determinants of prosocial behavior. Here we report two experiments which analyzed the influence of dispositional (prosocialness; rejection sensitivity and motivational variables (prosocial self-efficacy; prosocial collective efficacy; trust; anger; social affiliation motivation on prosocial behavior under neutral contexts (Study 1, and once under inclusion or exclusion conditions (Study 2. Both studies provided evidence for the predicted mediation of prosocial behavior. Results in both neutral and inclusion and exclusion conditions supported our predictive model of prosocial behavior. In the model dispositional variables predicted motivational variables, which in turn predicted prosocial behavior. We showed that the investigated variables predicted prosocial behavior; this suggests that to promote prosocial behavior one could (1 foster prosocialness, prosocial self and collective efficacy, trust in others and affiliation motivation and (2 try to reduce negative feelings and the tendency to dread rejection in an attempt to reduce the negative impact that these variables have on prosocial behavior. Moreover, the few differences that emerged in the model between the inclusion and exclusion contexts suggested that in interventions with excluded individuals special care emphasis should be placed on addressing rejection sensitivity and lack of trust.

  9. Interpopulation variation in contour feather structure is environmentally determined in great tits. (United States)

    Broggi, Juli; Gamero, Anna; Hohtola, Esa; Orell, Markku; Nilsson, Jan-Åke


    The plumage of birds is important for flying, insulation and social communication. Contour feathers cover most of the avian body and among other functions they provide a critical insulation layer against heat loss. Feather structure and composition are known to vary among individuals, which in turn determines variation in the insulation properties of the feather. However, the extent and the proximate mechanisms underlying this variation remain unexplored. We analyzed contour feather structure from two different great tit populations adapted to different winter regimes, one northern population in Oulu (Finland) and one southern population in Lund (Sweden). Great tits from the two populations differed significantly in feather structure. Birds from the northern population had a denser plumage but consisting of shorter feathers with a smaller proportion containing plumulaceous barbs, compared with conspecifics from the southern population. However, differences disappeared when birds originating from the two populations were raised and moulted in identical conditions in a common-garden experiment located in Oulu, under ad libitum nutritional conditions. All birds raised in the aviaries, including adult foster parents moulting in the same captive conditions, developed a similar feather structure. These feathers were different from that of wild birds in Oulu but similar to wild birds in Lund, the latter moulting in more benign conditions than those of Oulu. Wild populations exposed to different conditions develop contour feather differences either due to plastic responses or constraints. Environmental conditions, such as nutrient availability during feather growth play a crucial role in determining such differences in plumage structure among populations.

  12. Inadequate evaluation and management of threats in Australia's Marine Parks, including the Great Barrier Reef, misdirect Marine conservation. (United States)

    Kearney, Bob; Farebrother, Graham


    The magnificence of the Great Barrier Reef and its worthiness of extraordinary efforts to protect it from whatever threats may arise are unquestioned. Yet almost four decades after the establishment of the Great Barrier Reef Marine Park, Australia's most expensive and intensely researched Marine Protected Area, the health of the Reef is reported to be declining alarmingly. The management of the suite of threats to the health of the reef has clearly been inadequate, even though there have been several notable successes. It is argued that the failure to prioritise correctly all major threats to the reef, coupled with the exaggeration of the benefits of calling the park a protected area and zoning subsets of areas as 'no-take', has distracted attention from adequately addressing the real causes of impact. Australia's marine conservation efforts have been dominated by commitment to a National Representative System of Marine Protected Areas. In so doing, Australia has displaced the internationally accepted primary priority for pursuing effective protection of marine environments with inadequately critical adherence to the principle of having more and bigger marine parks. The continuing decline in the health of the Great Barrier Reef and other Australian coastal areas confirms the limitations of current area management for combating threats to marine ecosystems. There is great need for more critical evaluation of how marine environments can be protected effectively and managed efficiently.

  18. Determinants of a GP visit and cervical cancer screening examination in Great Britain.

    Directory of Open Access Journals (Sweden)

    Alexander Michael Labeit

    Full Text Available In the UK, women are requested to attend a cervical cancer test every 3 years as part of the NHS Cervical Screening Programme. This analysis compares the determinants of a cervical cancer screening examination with the determinants of a GP visit in the same year and investigates if cervical cancer screening participation is more likely for women who visit their GP.A recursive probit model was used to analyse the determinants of GP visits and cervical cancer screening examinations. GP visits were considered to be endogenous in the cervical cancer screening examination. The analysed sample consisted of 52,551 observations from 8,386 women of the British Household Panel Survey.The analysis showed that a higher education level and a worsening self-perceived health status increased the probability of a GP visit, whereas smoking decreased the probability of a GP visit. GP visits enhanced the uptake of a cervical cancer screening examination in the same period. The only variables which had the same positive effect on both dependent variables were higher education and living with a partner. The probability of a cervical cancer screening examination increased also with previous cervical cancer screening examinations and being in the recommended age groups. All other variables had different results for the uptake of a GP visit or a cervical cancer screening examination.Most of the determinants of visiting a GP and cervical cancer screening examination differ from each other and a GP visit enhances the uptake of a smear test.

  19. Determination of Preliminary Orbital Elements of the Great Comet C/1665 in Korean History

    Full Text Available There are many astronomical records of comets in Korean history books. We collected those of the comet that appeared in the winter of the year 1664. These records were written in Daily Reports of the Royal Observatory on Astronomical Events, Final Reports of the Royal Observatory on An Astronomical Events , the Daily Records of the Royal Secretariat of the Joseon Dynasty, and the Chronicle of the Joseon Dynasty. We used the Olbers' method for determination of preliminary orbit of the comet, and compared the result with the previous researches. In the Oblers' method the orbit is assumed to be parabolic (e=1. We obtained the following orbital elements: perifocal distance q=1.07 +- 0.008 AU, perifocal passage time T=2329 165.50 +- 0.72 days, argument of the perifocus omega =318°2 +- 2°29, longitude of ascending node Omega =85°23 +- 2°53 (J1665, inclination i=160°28 +- 1°56.

  20. Great Lakes water quality initiative technical support document for the procedure to determine bioaccumulation factors. Draft report

    International Nuclear Information System (INIS)


    The purpose of the document is to provide the technical information and rationale in support of the proposed procedures to determine bioaccumulation factors. Bioaccumulation factors, together with the quantity of aquatic organisms eaten, determine the extent to which people and wildlife are exposed to chemicals through the consumption of aquatic organisms. The more bioaccumulative a pollutant is, the more important the consumption of aquatic organisms becomes as a potential source of contaminants to humans and wildlife. Bioaccumulation factors are needed to determine both human health and wildlife tier I water quality criteria and tier II values. Also, they are used to define Bioaccumulative Chemicals of Concern among the Great Lakes Initiative universe of pollutants. Bioaccumulation factors range from less than one to several million

    Full Text Available At present, quality of life and self-determination begin to position itself as a key axis in interventions aimed at students with disabilities, motivating the interest of researchers and professionals to know their general well-being. This article evaluates the quality of life and self-determination of students with intellectual and developmental disabilities enrolled in regular schools. A case study methodology, descriptive-interpretative, is used through mixed data collection methods. The instruments used are Questionnaire for Assessment the Quality of Life in Teen Students (CCVA and ARC-INICO Scale for Assessment Self-Determination (for 14 students and interviews (for four teachers. A descriptive statistical analysis, contextualized by the extracted information from the interviews, was conducted. The results show high scores in different domains of quality of life, apart from emotional well-being, community inclusion and self-determination that are improvable. Adequate perception of students is observed about their ability to make decisions, choices and a good predisposition take control in different areas of their life. It is necessary to continue inquiring about the impact of educational environment, attitude and perception of teachers and the opportunities offered to students to act self-determined and increase their quality of life.

  4. Improved morphed potentials for Ar-HBr including scaling to the experimentally determined dissociation energy. (United States)

    Wang, Z; McIntosh, A L; McElmurry, B A; Walton, J R; Lucchese, R R; Bevan, J W


    A lead salt diode infrared laser spectrometer has been employed to investigate the rotational predissociation in Ar-HBr for transitions up to J' = 79 in the v(1) HBr stretching vibration of the complex using a slit jet and static gas phase. Line-shape analysis and modeling of the predissociation lifetimes have been used to determine a ground-state dissociation energy D(0) of 130(1) cm(-1). In addition, potential energy surfaces based on ab initio calculations are scaled, shifted, and dilated to generate three-dimensional morphed potentials for Ar-HBr that reproduce the measured value of D(0) and that have predictive capabilities for spectroscopic data with nearly experimental uncertainty. Such calculations also provide a basis for making a comprehensive comparison of the different morphed potentials generated using the methodologies applied.

  5. Precise orbit determination of Multi-GNSS constellation including GPS GLONASS BDS and GALIEO (United States)

    Dai, Xiaolei


    In addition to the existing American global positioning system (GPS) and the Russian global navigation satellite system (GLONASS), the new generation of GNSS is emerging and developing, such as the Chinese BeiDou satellite navigation system (BDS) and the European GALILEO system. Multi-constellation is expected to contribute to more accurate and reliable positioning and navigation service. However, the application of multi-constellation challenges the traditional precise orbit determination (POD) strategy that was designed usually for single constellation. In this contribution, we exploit a more rigorous multi-constellation POD strategy for the ongoing IGS multi-GNSS experiment (MGEX) where the common parameters are identical for each system, and the frequency- and system-specified parameters are employed to account for the inter-frequency and inter-system biases. Since the authorized BDS attitude model is not yet released, different BDS attitude model are implemented and their impact on orbit accuracy are studied. The proposed POD strategy was implemented in the PANDA (Position and Navigation Data Analyst) software and can process observations from GPS, GLONASS, BDS and GALILEO together. The strategy is evaluated with the multi-constellation observations from about 90 MGEX stations and BDS observations from the BeiDou experimental tracking network (BETN) of Wuhan University (WHU). Of all the MGEX stations, 28 stations record BDS observation, and about 80 stations record GALILEO observations. All these data were processed together in our software, resulting in the multi-constellation POD solutions. We assessed the orbit accuracy for GPS and GLONASS by comparing our solutions with the IGS final orbit, and for BDS and GALILEO by overlapping our daily orbit solution. The stability of inter-frequency bias of GLONASS and inter-system biases w.r.t. GPS for GLONASS, BDS and GALILEO were investigated. At last, we carried out precise point positioning (PPP) using the multi

  6. Determination of Fetal RHD Genotype Including the RHD Pseudogene in Maternal Plasma. (United States)

    Ziza, Karen Chinoca; Liao, Adolfo Wenjaw; Dezan, Marcia; Dinardo, Carla Luana; Jens, Eduardo; Francisco, Rossana Pulcineli Vieira; Junior, Alfredo Mendrone; Zugaib, Marcelo; Levi, José Eduardo


    To examine the accuracy of fetal RHD genotype and RHD pseudogene determination in a multiethnical population. Prospective study involving D-negative pregnant women. Cell-free DNA was extracted from 1 ml of maternal plasma by an automated system (MagNA Pure Compact, Roche) and real-time PCR was performed in triplicate targeting the RHD gene exons 5 and 7. Inconclusive samples underwent RHD pseudogene testing by real-time PCR analysis employing novel primers and probe. A positive result was observed in 128/185 (69.2%) samples and negative in 50 (27.0%). Umbilical cord blood phenotype confirmed all cases with a positive or negative PCR result. Seven (3.8%) cases were found inconclusive (exon 7 amplification only) and RHD pseudogene testing with both conventional and real-time PCR demonstrated a positive result in five of them, while two samples were also RHD pseudogene negative. Real-time PCR targeting RHD exons 5 and 7 simultaneously in maternal plasma is an accurate method for the diagnosis of fetal D genotype in our population. The RHD pseudogene real-time PCR assay is feasible and is particularly useful in populations with a high prevalence of this allele. © 2016 Wiley Periodicals, Inc.

  7. Great Comets (United States)

    Burnham, Robert


    Spectacular and mysterious objects that come and go in the night sky, comets have dwelt in our popular culture for untold ages. As remnants from the formation of the Solar system, they are objects of key scientific research and space missions. As one of nature's most potent and dramatic dangers, they pose a threat to our safety--and yet they were the origin of our oceans and perhaps even life itself. This beautifully illustrated book tells the story of the biggest and most awe-inspiring of all comets: those that have earned the title "Great." Robert Burnham focuses on the Great comets Hyakutake in 1996 and Hale-Bopp in 1997, which gripped attention worldwide because, for many, they were the first comets ever seen. He places these two recent comets in the context of their predecessors from past ages, among them the famous Comet Halley. Great Comets explains the exciting new discoveries that have come from these magnificent objects and profiles the spaceprobes to comets due for launch in the next few years. The book even takes a peek behind Hollywood's science-fiction fantasies to assess the real risks humanity faces from potential impacts of both comets and asteroids. For everyone interested in astronomy, this exciting book reveals the secrets of the Great Comets and provides essential tools for keeping up to date with comet discoveries in the future. Robert Burnham has been an amateur astronomer since the mid-1950s. He has been a senior editor of Astronomy magazine (1986-88) and is the author of many books and CD-ROMS, including Comet Hale-Bopp: Find and Enjoy the Great Comet and Comet Explorer.

  8. The determination, assessment, and design of "in-stream value" studies for the northern Great Plains region (United States)

    Bovee, Ken D.


    An extensive literature review was conducted to determine the discharge requirements of various components of a warm water fishery. Where exact hydrologic parameters were not measured directly in individual studies, they were estimated from inferred statements and knowledge of hydrologic variables leading to certain instream conditions. From this information it was possible to determine which components of the stream community would be most seriously affected by reduced discharges. In addition, a number of different methods used in the recommendation of minimum streamflows was reviewed. These methods were evaluated for their reliability and ease of use. It was concluded that a method for recommending minimum discharges should not sacrifice reliability for expediency. A methodology is proposed for the recommendation of minimum discharges for a warm water fishery. This method utilizes field measurements of critical stream areas and biological criteria determined from the used of indicator species. For large rivers, migration and spawning requirements are analyzed using the paddlefish (Polyodon spathula) as the indicator species. For smaller rivers, the suggested indicator species is the sauger (Stizostedion canadense). Rearing flows are determined on the basis of stream productivity by analyzing macroinvertebrate habits, and on the basis of fish habitat typing. The indicator species for determining adequate fish habitat is the stonecat (Notorus flavus). A number of variables were identified which might require a greater amount of in-stream flow than the fishery, per se. These variables included streamflow needs for riparian and other sub-irrigated vegetation, water quality parameters, anchor ice formation, and the relationship between discharge and sediment yield. Information concerning these variables is insufficient at this time to determine whether a variable will "over-ride" the streamflow requirement for the fishery itself. Further research is needed in these

  10. Climatic gradients and human development pressure determine spatial patterns of forest fragmentation in the Great Lakes basin, USA (United States)

    Currie, W. S.; Hart, S.


    Over half of temperate forest area globally has been fragmented or deforested by human activities. Our objective was to gain insight into the combination of climatic, ecological, and social factors that control complex spatial patterns of forest cover and fragmentation at the regional scale. Our study area was the US portion of the land area of the Laurentian Great Lakes basin (USGL basin) of the Upper Midwest, USA, covering ca. 300,000 km2 and home to 25 million people. While this region was historically forested, today there are regional gradients in forest cover as well as complex spatial patterns of agriculture, human settlements, and tree cover. This includes large expanses of fragmented forests in the wildland-urban interface or the forest transition zone. We used structural equation modeling to test models of social and climatic-ecological factors to explain spatial patterns of forest cover and fragmentation. This is a model-driven approach to statistical analysis that is used to test proposed causal "structures" of direct and indirect relationships among variables. It is an innovative approach that makes use of large spatial datasets to test understanding. We assembled numerous spatial data layers at 1 km2 resolution across the USGL basin. We found that 64% to 75% of variance in tree cover and forest connectivity was explained through a relatively simple model combining climatic gradients and human development pressure. Human development pressure was best represented as a measurement model that explained 45% of variance in road density and 87% of housing unit density, while significantly explaining patterns of forest fragmentation. Climate could be represented by a single variable, temperature: where temperature was higher, tree cover and forest connectivity was lower due to human land use. Temperatures did not help to explain patterns of human development as roads and housing, but did affect forest fragmentation through land use as cropland. This suggests

  11. Great Lakes (United States)

    Edsall, Thomas A.; Mac, Michael J.; Opler, Paul A.; Puckett Haecker, Catherine E.; Doran, Peter D.


    The Great Lakes region, as defined here, includes the Great Lakes and their drainage basins in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, and New York. The region also includes the portions of Minnesota, Wisconsin, and the 21 northernmost counties of Illinois that lie in the Mississippi River drainage basin, outside the floodplain of the river. The region spans about 9º of latitude and 20º of longitude and lies roughly halfway between the equator and the North Pole in a lowland corridor that extends from the Gulf of Mexico to the Arctic Ocean.The Great Lakes are the most prominent natural feature of the region (Fig. 1). They have a combined surface area of about 245,000 square kilometers and are among the largest, deepest lakes in the world. They are the largest single aggregation of fresh water on the planet (excluding the polar ice caps) and are the only glacial feature on Earth visible from the surface of the moon (The Nature Conservancy 1994a).The Great Lakes moderate the region’s climate, which presently ranges from subarctic in the north to humid continental warm in the south (Fig. 2), reflecting the movement of major weather masses from the north and south (U.S. Department of the Interior 1970; Eichenlaub 1979). The lakes act as heat sinks in summer and heat sources in winter and are major reservoirs that help humidify much of the region. They also create local precipitation belts in areas where air masses are pushed across the lakes by prevailing winds, pick up moisture from the lake surface, and then drop that moisture over land on the other side of the lake. The mean annual frost-free period—a general measure of the growing-season length for plants and some cold-blooded animals—varies from 60 days at higher elevations in the north to 160 days in lakeshore areas in the south. The climate influences the general distribution of wild plants and animals in the region and also influences the activities and distribution of the human

  12. Expanding client-centred thinking to include social determinants: a practical scenario based on the occupation of breastfeeding. (United States)

    Pitonyak, Jennifer S; Mroz, Tracy M; Fogelberg, Donald


    Client-centred thinking in occupational therapy underemphasizes the influence of social determinants and societal-level factors on occupation across the life course. When client-centred thinking focuses solely on the local or immediate contexts of individuals, therapists may not fully recognize or understand how social determinants can create barriers to occupational participation and performance. This article critically examines gaps in traditional thinking concerning client-centredness and demonstrates how the complex interplay between social determinants and societal-level factors may lead to occupational injustices. A practical example from a recent study on breastfeeding and accompanying scenario is used to examine limitations in current client-centred reasoning. The Life Course Health Development framework, a theoretical framework examining contexts of health disparities, is applied to illustrate the opportunity to expand thinking about client-centredness. The Life Course Health Development framework may be a useful addition to client-centred thinking about social determinants of occupation. Expanding client-centred thinking to include awareness, understanding, and respect for social determinants of occupation may enhance therapist-client interactions and outcomes of the occupational therapy process, and address gaps in current thinking that may contribute to occupational injustices.

  14. Determinants of Growth in Multiunit Housing Demand since the Great Recession: An Age-Period-Cohort Analysis

    Directory of Open Access Journals (Sweden)

    Shiv N. Mehrotra


    Full Text Available Following the Great Recession (2007–2009, growth in multiunit housing starts has been exceptionally strong and sustained. In this study, we examine empirical evidence for three possible explanations, namely, the passage of Baby Boomers into senior years, the depressed economic conditions, and rising preference of recent birth cohorts for residing in urban cores. Applying Age-Period-Cohort analysis to census data on multiunit housing occupancy from 1970 to 2010, we find evidence to support the explanations that a sharp increase in demand from Millennials drawn to urban cores and retiring Baby Boomers are contributing to the growth in multiunit housing starts. The results provide weak evidence of a negative relationship between depressed economic conditions and demand for multiunit housing starts. Over the long term, demand for multiunit housing can be expected to moderate as a result of the projected aging of the population.

  15. 3-D MDT with spherical targets by bilinear interpolation for determining blood velocity profiles including the vessel wall effect (United States)

    Choomphon-anomakhun, Natthaphon; Natenapit, Mayuree


    A numerical simulation of three-dimensional (3-D) implant assisted-magnetic drug targeting (IA-MDT) using ferromagnetic spherical targets, including the effect from the vessel wall on the blood flow, is presented. The targets were implanted within arterioles and subjected to an externally uniform applied magnetic field in order to increase the effectiveness of targeting magnetic drug carrier particles (MDCPs). The capture area (As) of the MDCPs was determined by inspection of the particle trajectories simulated from the particle equations of motion. The blood flow velocities at any particle position around the target were obtained by applying bilinear interpolation to the numerical blood velocity data. The effects on As of the type of ferromagnetic materials in the targets and MDCPs, average blood flow rates, mass fraction of the ferromagnetic material in the MDCPs, average radii of MDCPs (Rp) and the externally applied magnetic field strength (μ0H0) were evaluated. Furthermore, the appropriate μ0H0 and Rp for the IA-MDT design is suggested. In the case of the SS409 target and magnetite MDCPs, dimensionless capture areas ranging from 4.1- to 12.4 and corresponding to particle capture efficiencies of 31-94% were obtained with Rp ranging from 100- to 500 nm, weight fraction of 80%, μ0H0 of 0.6 T and an average blood flow rate of 0.01 ms-1. In addition, the more general 3-D modelling of IA-MDT in this work is applicable to IA-MDT using spherical targets implanted within blood vessels for both laminar and potential blood flows including the wall effect.

  16. Great Apes (United States)

    Sleeman, Jonathan M.; Cerveny, Shannon


    Anesthesia of great apes is often necessary to conduct diagnostic analysis, provide therapeutics, facilitate surgical procedures, and enable transport and translocation for conservation purposes. Due to the stress of remote delivery injection of anesthetic agents, recent studies have focused on oral delivery and/or transmucosal absorption of preanesthetic and anesthetic agents. Maintenance of the airway and provision of oxygen is an important aspect of anesthesia in great ape species. The provision of analgesia is an important aspect of the anesthesia protocol for any procedure involving painful stimuli. Opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are often administered alone, or in combination to provide multi-modal analgesia. There is increasing conservation management of in situ great ape populations, which has resulted in the development of field anesthesia techniques for free-living great apes for the purposes of translocation, reintroduction into the wild, and clinical interventions.

  17. "Great Job Cleaning Your Plate Today!" Determinants of Child-Care Providers' Use of Controlling Feeding Practices: An Exploratory Examination. (United States)

    Dev, Dipti A; McBride, Brent A; Speirs, Katherine E; Blitch, Kimberly A; Williams, Natalie A


    National early childhood obesity prevention policies recommend that child-care providers avoid controlling feeding practices (CFP) (eg, pressure-to-eat, food as reward, and praising children for cleaning their plates) with children to prevent unhealthy child eating behaviors and childhood obesity. However, evidence suggests that providers frequently use CFP during mealtimes. Using the Academy of Nutrition and Dietetics (2011) benchmarks for nutrition in child care as a framework, researchers assessed child-care providers' perspectives regarding their use of mealtime CFP with young children (aged 2 to 5 years). Using a qualitative design, individual, face-to-face, semi-structured interviews were conducted with providers until saturation was reached. Providers were selected using maximum variation purposive sampling from varying child-care contexts (Head Start, Child and Adult Care Food Program [CACFP]-funded centers, non-CACFP programs). All providers were employed full-time in Head Start or state-licensed center-based child-care programs, cared for children (aged 2 to 5 years), and were directly responsible for serving meals and snacks. Child-care providers' perspectives regarding CFP. Thematic analysis using NVivo (version 9, 2010, QSR International Pty Ltd) to derive themes. Providers' perspectives showed barriers, motivators, and facilitators regarding their use of mealtime CFP. Providers reported barriers to avoiding CFP such as CFP were effective for encouraging desired behaviors, misconceptions that providers were encouraging but not controlling children's eating, and fear of parents' negative reaction if their child did not eat. Providers who did not practice CFP were motivated to avoid CFP because they were unnecessary for encouraging children to eat, and they resulted in negative child outcomes and obesity. Facilitators as an alternative to CFP included practicing healthful feeding practices such as role modeling, peer modeling, and sensory exploration of

    The isotopic compositions of elements are often used to characterize nucelosynthetic contributions in early Solar System objects. Coordinated multiple middle-mass elements with differing volatilities may provide information regarding the location of condensation of early Solar System solids. Here we detail new procedures that we have developed to make high-precision multi-isotope measurements of chromium and calcium using thermal ionization mass spectrometry, and characterize a suite of chondritic and terrestrial material including two fragments of the Chelyabinsk LL-chondrite.

  3. Determination of water-extractable nonstructural carbohydrates, including inulin, in grass samples with high-performance anion exchange chromatography and pulsed amperometric detection. (United States)

    Raessler, Michael; Wissuwa, Bianka; Breul, Alexander; Unger, Wolfgang; Grimm, Torsten


    The exact and reliable determination of carbohydrates in plant samples of different origin is of great importance with respect to plant physiology. Additionally, the identification and quantification of carbohydrates are necessary for the evaluation of the impact of these compounds on the biogeochemistry of carbon. To attain this goal, it is necessary to analyze a great number of samples with both high sensitivity and selectivity within a limited time frame. This paper presents a rugged and easy method that allows the isocratic chromatographic determination of 12 carbohydrates and sugar alcohols from one sample within 30 min. The method was successfully applied to a variety of plant materials with particular emphasis on perennial ryegrass samples of the species Lolium perenne. The method was easily extended to the analysis of the polysaccharide inulin after its acidic hydrolysis into the corresponding monomers without the need for substantial change of chromatographic conditions or even the use of enzymes. It therefore offers a fundamental advantage for the analysis of the complex mixture of nonstructural carbohydrates often found in plant samples.

  4. Determination of point isotropic buildup factors of gamma rays including incoherent and coherent scattering for aluminum, iron, lead, and water by discrete ordinates method

    International Nuclear Information System (INIS)

    Kitsos, S.; Assad, A.; Diop, C.M.; Nimal, J.C.


    Exposure and energy absorption buildup factors for aluminum, iron, lead, and water are calculated by the SNID discrete ordinates code for an isotropic point source in a homogeneous medium. The calculation of the buildup factors takes into account the effects of both bound-electron Compton (incoherent) and coherent (Rayleigh) scattering. A comparison with buildup factors from the literature shows that these two effects greatly increase the buildup factors for energies below a few hundred kilo-electron-volts, and thus the new results are improved relative to the experiment. This greater accuracy is due to the increase in the linear attenuation coefficient, which leads to the calculation of the buildup factors for a mean free path with a smaller shield thickness. On the other hand, for the same shield thickness, exposure increases when only incoherent scattering is included and decreases when only coherent scattering is included, so that the exposure finally decreases when both effects are included. Great care must also be taken when checking the approximations for gamma-ray deep-penetration transport calculations, as well as for the cross-section treatment and origin

  5. Sense of place as a determinant of people's attitudes towards the environment: implications for natural resources management and planning in the Great Barrier Reef, Australia. (United States)

    Larson, Silva; De Freitas, Debora M; Hicks, Christina C


    Integrating people's values and perceptions into planning is essential for the successful management of natural resources. However, successful implementation of natural resources management decisions on the ground is a complex task, which requires a comprehensive understanding of a system's social and ecological linkages. This paper investigates the relationship between sense of place and people's attitudes towards their natural environment. Sense of place contributes towards shaping peoples' beliefs, values and commitments. Here, we set out to explore how these theoretical contributions can be operationalized for natural resources management planning in the Great Barrier Reef region of Australia. We hypothesise that the region's diverse range of natural resources, conservation values and management pressures might be reflected in people's attachment to place. To tests this proposition, variables capturing socio-demographics, personal wellbeing and a potential for sense of place were collected via mail-out survey of 372 residents of the region, and tested for relationships using multivariate regression and redundancy orientation analyses. Results indicate that place of residence within the region, involvement in community activities, country of birth and the length of time respondents lived in the region are important determinants of the values assigned to factors related to the natural environment. This type of information is readily available from National Census and thus could be incorporated into the planning of community engagement strategies early in the natural resources management planning process. A better understanding of the characteristics that allow sense of place meanings to develop can facilitate a better understanding of people's perceptions towards environmental and biodiversity issues. We suggest that the insights gained from this study can benefit environmental decision making and planning in the Great Barrier Reef region; and that sense of place

    Berg, Larry K.; Riihimaki, Laura D.; Qian, Yun; Yan, Huiping; Huang, Maoyi


    This study utilizes five commonly used reanalysis products, including the NCEP-DOE Reanalysis 2 (NCEP2), ECMWF Re-Analysis (ERA)-Interim, Japanese 25-year Reanalysis (JRA-25), Modern-Era Retrospective Analysis for Research and Applications (MERRA), and North American Regional Reanalysis (NARR) to evaluate features of the Southern Great Plains Low Level Jet (LLJ) above the Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) Southern Great Plains site. Two sets of radiosonde data are utilized: the six-week Midlatitude Continental Convective Clouds Experiment (MC3E), and a ten-year period spanning 2001-2010. All five reanalysis are compared to MC3E data, while only the NARR and MERRA are compared to the ten-year data. Each reanalysis is able to represent most aspects of the composite LLJ profile, although there is a tendency for each reanalysis to overestimate the wind speed between the nose of the LLJ and 700 mb. There are large discrepancies in the number of LLJ observed and derived from the reanalysis, particularly for strong LLJs that leads to an underestimate of the water vapor transport associated with LLJs. When the ten-year period is considered, the NARR overestimates and MERRA underestimates the total moisture transport, but both underestimate the transport associated with strong LLJs by factors of 2.0 and 2.7 for the NARR and MERR, respectively. During MC3E there were differences in the patterns of moisture convergence and divergence, with the MERRA having an area of moisture divergence over Oklahoma, while the NARR has moisture convergence. The patterns of moisture convergence and divergence are more consistent during the ten-year period.

    Predatory birds such as herons have been used as bioindicators of pollution since they are at the top of their food webs. The tissues of these animals are analyzed for assessing environmental pollution caused by toxic elements. In the present study, adequate experimental conditions were established for determination of trace elements concentrations in the liver samples of Great-white-egret (Ardea alba Linnaeus, 1758) for further application of this specimens as a bioindicator of environmental contamination. Four liver samples were collected from Greatwhite- egrets found in the metropolitan region of Sao Paulo and were they analyzed by the method of neutron activation analysis (NAA). Concentrations of the elements Br, Co, Cs, Fe, Na, Rb, Se and Zn were measured in these liver tissues. The findings of this present study demonstrated that the established procedure for liver sample treatment was appropriate to obtain a homogeneous sample. The method of neutron activation analysis (NAA) was very promising for liver sample analysis for evaluation of environmental contamination. (author)

  10. Why is the Great Red Spot Red? The Exogenic, Photolytic Origin of the UV/Blue-Absorbing Chromophores of Jupiter’s Great Red Spot as Determined by Spectral Analysis of Cassini/VIMS Observations using New Laboratory Optical Coefficients (United States)

    Baines, Kevin H.; Carlson, Robert W.; Momary, Thomas W.


    For centuries, a major question for Jupiter has been: Why is the Great Red Spot red? In particular, two major theories have been proposed: (1) that the coloring is due to photolytic processes in the upper cloud layer, or (2) it is due to the upwellimg of red materials processed relatively deep within the troposphere. Utilizing indices of refraction for red choromophores generated by the photolysis of ammonia and acetylene in the laboratory, we present results of a spectral analysis of the core of Jupiter’s Great Red Spot (GRS) as observed by the visual channel of the Cassini/Visual Infrared Mapping Spectrometer (VIMS). Consistent with the physical origin of such laboratory-generated chromophores in Jupiter - i.e., by solar-driven UV photolysis within the upper levels of the GRS structure near ~ 0.3 bar - our spectral modeling yields satisfactory results for such Mie scattering chromophores only when they are confined to the upper ~ 100 mbar of the GRS. Beneath this reddish upper cloud layer, our models indicate that the remainder of the GRS cloud - assumed to extend down to at least the ammonia condensation level near 0.6 bar - must be relatively spectrally bright throughout the UV-red spectrum; that is, they must be predominantly a whitish or grey color at depth. Thus, our 0.35-1.0 micron spectral models of the GRS are inconsistent with an endogenic origin of the reddish coloring originating in the depths of Jupiter, but are consistent with a photolytic origin due to the photolysis of ammonia and acetylene in the upper troposphere.

  12. What makes great boards great. (United States)

    Sonnenfeld, Jeffrey A


    In the wake of meltdowns at WorldCom, Tyco, and Enron, enormous attention has been focused on the companies' boards. It seems inconceivable that business disasters of such magnitude could happen without gross or even criminal negligence on the part of board members. And yet a close examination of those boards reveals no broad pattern of incompetence or corruption. In fact, they followed most of the accepted standards for board operations: Members showed up for meetings; they had money invested in the company; audit committees, compensation committees, and codes of ethics were in place; the boards weren't too small or too big, nor were they dominated by insiders. In other words, they passed the tests that would normally be applied to determine whether a board of directors was likely to do a good job. And that's precisely what's so scary, according to corporate governance expert Jeffrey Sonnenfeld, who suggests that it's time for some new thinking about how corporate boards operate and are evaluated. He proposes thinking not only about how to structure the board's work but also about how to manage it as a social system. Good boards are, very simply, high-functioning work groups. They're distinguished by a climate of respect, trust, and candor among board members and between the board and management. Information is shared openly and on time; emergent political factions are quickly eliminated. Members feel free to challenge one another's assumptions and conclusions, and management encourages lively discussion of strategic issues. Directors feel a responsibility to contribute meaningfully to the board's performance. In addition, good boards assess their own performance, both collectively and individually.

  14. A sensitive multi-residue method for the determination of 35 micropollutants including pharmaceuticals, iodinated contrast media and pesticides in water. (United States)

    Valls-Cantenys, Carme; Scheurer, Marco; Iglesias, Mònica; Sacher, Frank; Brauch, Heinz-Jürgen; Salvadó, Victoria


    A sensitive, multi-residue method using solid-phase extraction followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed to determine a representative group of 35 analytes, including corrosion inhibitors, pesticides and pharmaceuticals such as analgesic and anti-inflammatory drugs, five iodinated contrast media, β-blockers and some of their metabolites and transformation products in water samples. Few other methods are capable of determining such a broad range of contrast media together with other analytes. We studied the parameters affecting the extraction of the target analytes, including sorbent selection and extraction conditions, their chromatographic separation (mobile phase composition and column) and detection conditions using two ionisation sources: electrospray ionisation (ESI) and atmospheric pressure chemical ionisation (APCI). In order to correct matrix effects, a total of 20 surrogate/internal standards were used. ESI was found to have better sensitivity than APCI. Recoveries ranging from 79 to 134 % for tap water and 66 to 144 % for surface water were obtained. Intra-day precision, calculated as relative standard deviation, was below 34 % for tap water and below 21 % for surface water, groundwater and effluent wastewater. Method quantification limits (MQL) were in the low ng L(-1) range, except for the contrast agents iomeprol, amidotrizoic acid and iohexol (22, 25.5 and 17.9 ng L(-1), respectively). Finally, the method was applied to the analysis of 56 real water samples as part of the validation procedure. All of the compounds were detected in at least some of the water samples analysed.

    Background Gastroesophageal reflux disease (GERD) is a common cause of discomfort and morbidity worldwide. However, information on determinants of GERD from large-scale studies in low- to medium-income countries is limited. We investigated the factors associated with different measures of GERD symptoms, including frequency, patient-perceived severity, and onset time. Methods We performed a cross-sectional analysis of the baseline data from a population-based cohort study of ∼50,000 individuals in in Golestan Province, Iran. GERD symptoms in this study included regurgitation and/or heartburn. Results Approximately 20% of participants reported at least weekly symptoms. Daily symptoms were less commonly reported by men, those of Turkmen ethnicity, and nass chewers. On the other hand, age, body mass index, alcohol drinking, cigarette smoking, opium use, lower socioeconomic status, and lower physical activity were associated with daily symptoms. Most of these factors showed similar associations with severe symptoms. Women with higher BMI and waist to hip ratio were more likely to report frequent and severe GERD symptoms. Hookah smoking (OR 1.34, 95% CI 1.02–1.75) and opium use (OR 1.70, 95% CI 1.55–1.87) were associated with severe symptoms, whereas nass chewing had an inverse association (OR 0.87, 95% CI 0.76–0.99). After exclusion of cigarette smokers, hookah smoking was still positively associated and nass chewing was inversely associated with GERD symptoms (all frequencies combined). Conclusion GERD is common in this population. The associations of hookah and opium use and inverse association of nass use with GERD symptoms are reported for the first time. Further studies are required to investigate the nature of these associations. Other determinants of GERD were mostly comparable to those reported elsewhere. PMID:24586635

  19. Great Salt Lake, Utah (United States)

    Stephens, Doyle W.; Gardner, Joe F.


    This document is intended as a source of general information and facts about Great Salt Lake, Utah. This U.S. Geological Survey information sheet answers frequently asked questions about Great Salt Lake. Topics include: History, salinity, brine shrimp, brine flies, migratory birds, and recreation. Great Salt Lake, the shrunken remnant of prehistoric Lake Bonneville, has no outlet. Dissolved salts accumulate in the lake by evaporation. Salinity south of the causeway has ranged from 6 percent to 27 percent over a period of 22 years (2 to 7 times saltier than the ocean). The high salinity supports a mineral industry that extracts about 2 million tons of salt from the lake each year. The aquatic ecosystem consists of more than 30 species of organisms. Harvest of its best-known species, the brine shrimp, annually supplies millions of pounds of food for the aquaculture industry worldwide. The lake is used extensively by millions of migratory and nesting birds and is a place of solitude for people. All this occurs in a lake that is located at the bottom of a 35,000-square-mile drainage basin that has a human population of more than 1.5 million.

    The health of the Great Barrier Reef is presently assessed using the water column concentration of chlorophyll and suspended solids, and measured light penetration. Quantifying these water column properties over 2,000 km of often cloud-covered, sparsely sampled, and highly variable coastal waters is problematic. To provide the best estimate of water quality, we assimilating satellite remote-sensing reflectance (the ratio of water-leaving radiance versus water-entering irradiance) using an in-water optical model to produce an equivalent simulated remote-sensing reflectance, and calculate the mis-match between the observed and simulated quantities to constrain a complex biogeochemical model (eReefs) with a Deterministic Ensemble Kalman Filter (DEnKF). We compare the water quality properties of the data assimilating model with in-situ observations, as well as with withheld remote-sensed observations. As a final step, we consider whether withheld observations can be combined with the data-assimilation generated chlorophyll fields to provide the best estimate of the chlorophyll concentration given all the available information.

  2. Single particle ICP-MS as a tool for determining the stability of silver nanoparticles in aquatic matrixes under various environmental conditions, including treatment by ozonation. (United States)

    Telgmann, Lena; Nguyen, Michael Thanh Khoa; Shen, Li; Yargeau, Viviane; Hintelmann, Holger; Metcalfe, Chris D


    Silver nanoparticles (AgNPs) are used in a large number of consumer products due to their antimicrobial and antifungal properties, and these materials may be discharged into municipal wastewater. Wastewater treatment, including advanced oxidation processes (AOPs), may modify the forms of silver in wastewater before they are discharged into surface waters. In addition, little is known about the changes in AgNPs that occur in natural waters under different environmental conditions. In this project, we utilized single particle ICP-MS (spICP-MS) and dynamic light scattering (DLS) analytical techniques to evaluate changes in the number and size of AgNPs in laboratory experiments with milliQ water under different environmental conditions, as well as during ozonation. Changes in the number and size of AgNPs determined by spICP-MS were evidence of altered stability of the nanoparticles. Increased rates of dissolution occurred under extremes of pH. Lower temperature decreased the rate of dissolution of AgNP relative to the dissolution in treatments at room temperature. The addition of chloride resulted in the loss of AgNPs from suspension due to agglomeration and precipitation. Ozonation led to a rapid decline in the number and size of AgNPs, as indicated by both spICP-MS and DLS analysis. An increase in the concentration of dissolved silver in the ozone treatments was evidence that changes in particle size were a result of oxidative dissolution of AgNPs to silver ion. Graphical abstract Single particle ICP-MS is used to evaluate dissolution of silver nanoparticles under different environmental conditions, including water treatment by ozonation.

  3. FT-midIR determination of fatty acid profiles, including trans fatty acids, in bakery products after focused microwave-assisted Soxhlet extraction. (United States)

    Ruiz-Jiménez, J; Priego-Capote, F; Luque de Castro, M D


    A study of the feasibility of Fourier transform medium infrared spectroscopy (FT-midIR) for analytical determination of fatty acid profiles, including trans fatty acids, is presented. The training and validation sets-75% (102 samples) and 25% (36 samples) of the samples once the spectral outliers have been removed-to develop FT-midIR general equations, were built with samples from 140 commercial and home-made bakery products. The concentration of the analytes in the samples used for this study is within the typical range found in these kinds of products. Both sets were independent; thus, the validation set was only used for testing the equations. The criterion used for the selection of the validation set was samples with the highest number of neighbours and the most separation between them (H/=0.90, SEP=1-1.5 SEL and R (2)=0.70-0.89, SEP=2-3 SEL, respectively. The results obtained with the proposed method were compared with those provided by the conventional method based on GC-MS. At 95% significance level, the differences between the values obtained for the different fatty acids were within the experimental error.

  4. Clinical significance of combined determination of several tumor markers (including CYFRA21-1, NSE, CA-50 and CEA) in patients with pulmonary cancer

    Objective: To enhance the diagnosis of pulmonary cancer by determination of optimal combinations of various tumor markers. Methods: Serum CYFRA 21-1 , NSE, CA-50 (with RIA) and CEA (with CLIA) contents were determined in 107 patients with various types of pulmonary cancers, 66 patients with various benign pulmonary diseases and 59 controls. Results: It was revealed that CYFRA 21-1 determination was most sensitive for detection of squamous cell carcinoma. The same was true for CEA in the detection of adenocarcinoma. NSE determination was very specific for small cell carcinoma. Combined determinations of either CYFRA 21- l + NSE or CYFRA 21-1 + NSE + CEA were excellent for general screening. Conclusion: Combined determination of these tumor markers could be applied expediently as supplementary diagnostic measure for pulmonary malignancies. (authors)

  5. Determination of potassium in several plants and study of potassium transfer to different beverages, including tequila, by measurement of 40K (United States)

    Navarrete, J. M.; Muller, G.; Cabrera, L.; Martinez, T.


    Measurement of 40K was used for determination of potassium concentrations in leaves of agave and maguey cactus leaves, and coffee beans of various origins. The procedure was also used to study potassium transfer to tequila (alcoholic drink made of agave cactus), and the cactus and coffee infusions using 40K as a natural radioactive tracer. Counting of 40K in Marinelli containers with the aid of a low background NaI(Ti) scintillation detection system for 12 24 hours was employed. The method appeared to be simple and suitable for determination of potassium concentrations in large samples, which eliminates homogeneity problems.

  7. Characterization of a quadrant diamond transmission X-ray detector including a precise determination of the mean electron-hole pair creation energy. (United States)

    Keister, Jeffrey W; Cibik, Levent; Schreiber, Swenja; Krumrey, Michael


    Precise monitoring of the incoming photon flux is crucial for many experiments using synchrotron radiation. For photon energies above a few keV, thin semiconductor photodiodes can be operated in transmission for this purpose. Diamond is a particularly attractive material as a result of its low absorption. The responsivity of a state-of-the art diamond quadrant transmission detector has been determined, with relative uncertainties below 1% by direct calibration against an electrical substitution radiometer. From these data and the measured transmittance, the thickness of the involved layers as well as the mean electron-hole pair creation energy were determined, the latter with an unprecedented relative uncertainty of 1%. The linearity and X-ray scattering properties of the device are also described.

    On assignment of the Dutch Ministry of Economic Affairs ECN and KEMA investigated the financial gaps of renewable electricity production technologies. These form the basis for determining the level of the MEP-subsidies (subsidy for the environmental quality of power generation) for different renewable electricity sources and technologies by the Ministry. This report contains an advice on the financial gaps that are to be used for determining the subsidy levels. The calculation of the financial gaps is based on an earlier report on the inputs for the calculations and on the subsequent stakeholder consultation with respect to these inputs. A detailed description is given of the assumptions, calculations and stakeholder inputs underlying the financial gaps for the establishment of the MEP-subsidies for new projects starting from July 2006 till December 2007 [nl

  9. Motion-insensitive determination of B1+ amplitudes based on the bloch-siegert shift in single voxels of moving organs including the human heart. (United States)

    Dokumaci, Ayse Sila; Pouymayou, Bertrand; Kreis, Roland; Boesch, Chris


    To reliably determine the amplitude of the transmit radiofrequency ( B1+) field in moving organs like the liver and heart, where most current techniques are usually not feasible. B1+ field measurement based on the Bloch-Siegert shift induced by a pair of Fermi pulses in a double-triggered modified Point RESolved Spectroscopy (PRESS) sequence with motion-compensated crusher gradients has been developed. Performance of the sequence was tested in moving phantoms and in muscle, liver, and heart of six healthy volunteers each, using different arrangements of transmit/receive coils. B1+ determination in a moving phantom was almost independent of type and amplitude of the motion and agreed well with theory. In vivo, repeated measurements led to very small coefficients of variance (CV) if the amplitude of the Fermi pulse was chosen above an appropriate level (CV in muscle 0.6%, liver 1.6%, heart 2.3% with moderate amplitude of the Fermi pulses and 1.2% with stronger Fermi pulses). The proposed sequence shows a very robust determination of B1+ in a single voxel even under challenging conditions (transmission with a surface coil or measurements in the heart without breath-hold). © 2015 Wiley Periodicals, Inc.

  11. Determination of drugs in surface water and wastewater samples by liquid chromatography-mass spectrometry: Methods and preliminary results including toxicity studies with Vibrio fischeri (United States)

    Farre, M.; Ferrer, I.; Ginebreda, A.; Figueras, M.; Olivella, L.; Tirapu, L.; Vilanova, M.; Barcelo, D.


    In the present work a combined analytical method involving toxicity and liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) was developed for the determination of pharmaceutical compounds in water samples. The drugs investigated were the analgesics: ibuprofen, ketoprofen, naproxen, and diclofenac, the decomposition product of the acetyl salicylic acid: salicylic acid and one lipid lowering agent, gemfibrozil. The selected compounds are acidic substances, very polar and all of them are analgesic compounds that can be purchased without medical prescription. The developed protocol consisted, first of all, on the use Microtox?? and ToxAlert??100 toxicity tests with Vibrio fischeri for the different pharmaceutical drugs. The 50% effective concentration (EC50) values and the toxicity units (TU) were determined for every compound using both systems. Sample enrichment of water samples was achieved by solid-phase extraction procedure (SPE), using the Merck LiChrolut?? EN cartridges followed by LC-ESI-MS. Average recoveries loading 1 l of samples with pH=2 varied from 69 to 91% and the detection limits in the range of 15-56 ng/l. The developed method was applied to real samples from wastewater and surface-river waters of Catalonia (north-east of Spain). One batch of samples was analyzed in parallel also by High Resolution Gas Chromatography coupled with Mass Spectrometry (HRGC-MS) and the results have been compared with the LC-ESI-MS method developed in this work. ?? 2001 Elsevier Science B.V.

  12. Simultaneous determination of multiclass preservatives including isothiazolinones and benzophenone-type UV filters in household and personal care products by micellar electrokinetic chromatography. (United States)

    Lopez-Gazpio, Josu; Garcia-Arrona, Rosa; Millán, Esmeralda


    In this work, a simple and reliable micellar electrokinetic chromatography method for the separation and quantification of 14 preservatives, including isothiazolinones, and two benzophenone-type UV filters in household, cosmetic and personal care products was developed. The selected priority compounds are widely used as ingredients in many personal care products, and are included in the European Regulation concerning cosmetic products. The electrophoretic separation parameters were optimized by means of a modified chromatographic response function in combination with an experimental design, namely a central composite design. After optimization of experimental conditions, the BGE selected for the separation of the targets consisted of 60 mM SDS, 18 mM sodium tetraborate, pH 9.4 and 10% v/v methanol. The MEKC method was checked in terms of linearity, LODs and quantification, repeatability, intermediate precision, and accuracy, providing appropriate values (i.e. R(2) ≥ 0.992, repeatability RSD values ˂9%, and accuracy 90-115%). Applicability of the validated method was successfully assessed by quantifying preservatives and UV filters in commercial consumer products. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  15. Great Lakes Literacy Principles (United States)

    Fortner, Rosanne W.; Manzo, Lyndsey


    Lakes Superior, Huron, Michigan, Ontario, and Erie together form North America's Great Lakes, a region that contains 20% of the world's fresh surface water and is home to roughly one quarter of the U.S. population (Figure 1). Supporting a $4 billion sport fishing industry, plus $16 billion annually in boating, 1.5 million U.S. jobs, and $62 billion in annual wages directly, the Great Lakes form the backbone of a regional economy that is vital to the United States as a whole (see Yet the grandeur and importance of this freshwater resource are little understood, not only by people in the rest of the country but also by many in the region itself. To help address this lack of knowledge, the Centers for Ocean Sciences Education Excellence (COSEE) Great Lakes, supported by the U.S. National Science Foundation and the National Oceanic and Atmospheric Administration, developed literacy principles for the Great Lakes to serve as a guide for education of students and the public. These “Great Lakes Literacy Principles” represent an understanding of the Great Lakes' influences on society and society's influences on the Great Lakes.

    Paul A Brown

    Full Text Available Four avian metapneumovirus (AMPV subgroups (A-D have been reported previously based on genetic and antigenic differences. However, until now full length sequences of the only known isolates of European subgroup C and subgroup D viruses (duck and turkey origin, respectively have been unavailable. These full length sequences were determined and compared with other full length AMPV and human metapneumoviruses (HMPV sequences reported previously, using phylogenetics, comparisons of nucleic and amino acid sequences and study of codon usage bias. Results confirmed that subgroup C viruses were more closely related to HMPV than they were to the other AMPV subgroups in the study. This was consistent with previous findings using partial genome sequences. Closer relationships between AMPV-A, B and D were also evident throughout the majority of results. Three metapneumovirus "clusters" HMPV, AMPV-C and AMPV-A, B and D were further supported by codon bias and phylogenetics. The data presented here together with those of previous studies describing antigenic relationships also between AMPV-A, B and D and between AMPV-C and HMPV may call for a subclassification of metapneumoviruses similar to that used for avian paramyxoviruses, grouping AMPV-A, B and D as type I metapneumoviruses and AMPV-C and HMPV as type II.

  19. Determination of Single Sugars, Including Inulin, in Plants and Feed Materials by High-Performance Liquid Chromatography and Refraction Index Detection

    Directory of Open Access Journals (Sweden)

    Kirsten Weiß


    Full Text Available The exact and reliable detection of sugar monomers and fructans provides important information for the evaluation of carbohydrate metabolism in plants and animals. Using the HPLC method; a large number of samples and single sugars; with both high sensitivity and selectivity; may be analysed. It was shown that the described method—using a Nucleosil column loaded with Pb2+ ions; a refractive index detector (RID; and HPLC-grade water as the eluent—gives precise and reproducible results regarding the detection of individual sugars in extracts of plants and feed materials. The method can be applied for the detection of sucrose; maltose; lactose; xylose; glucose; galactose; arabinose; fructose; ribose; and mannitol. Furthermore; depending on the plant material; the sugars verbascose; stachyose; and raffinose can be separated. The peaks were well resolved and the reproducibility of the analysis; with 94–108% of recovery (RC and relative standard deviation (RSD of up to 5%; was very good. The method was successfully applied to a variety of green forages and samples of sugar beet pulp silages. It is also possible to determine fructan with inulin as a standard; together with the other sugars; or alone by a different protocol and column.

  20. Deep tissue biopsy vs. superficial swab culture, including microbial loading determination, in the microbiological assessment of Skin and Soft Tissue Infections (SSTIs). (United States)

    Esposito, Silvano; De Simone, Giuseppe; Gioia, Renato; Noviello, Silvana; Pagliara, Domenico; Campitiello, Nicola; Rubino, Corrado; Lo Pardo, Dante; Boccia, Giovanni; De Caro, Francesco; Ascione, Tiziana


    Thirty-two patients affected by SSTIs including DFIs were enrolled between 2013 and 2014. Superficial swab was obtained before and after cleansing with sterile saline, and after ultrasonic debridement; deep tissue biopsy was obtained from ulcer base. Samples were diluted with 1 mL of saline, serial 10-fold dilutions to 10 -6 were made and 50 μL of each dilution was plated onto appropriate media. Bacteria were identified by Vitek II system. Microbial load was expressed as CFU/mL. Statistical analysis was performed by χ2. Incidence of Gram positives was higher than Gram negatives (S. aureus and P. aeruginosa being the most frequent); concordance (same bacteria isolated before and after debridement) never exceeded 60%. Ultrasonic debridement significantly reduced bacterial load or even suppressed bacterial growth. While reliability of superficial swab is poor for microbiological diagnosis of SSTIs, swabbing after ultrasonic debridement and biopsy of the ulcer base may be equally reliable.

  1. Determination of sulfur forms in wine including free and total sulfur dioxide based on molecular absorption of carbon monosulfide in the air-acetylene flame. (United States)

    Huang, Mao Dong; Becker-Ross, Helmut; Florek, Stefan; Heitmann, Uwe; Okruss, Michael; Patz, Claus-Dieter


    A new method for the determination of sulfur forms in wine, i.e., free SO(2), total SO(2), bound SO(2), total S, and sulfate, is presented. The method is based on the measurement of the carbon monosulfide (CS) molecular absorption produced in a conventional air-acetylene flame using high-resolution continuum source absorption spectrometry. Individual sulfur forms can be distinguished because of the different sensitivities of the corresponding CS molecular absorption. The sensitivity of free SO(2) is about three times higher than the value for bound SO(2) and sulfate. The method makes use of procedures similar to those used in classic reference methods. Its performance is verified by analyzing six wine samples. Relative standard deviations are between 5 and 13% for free SO(2) and between 1 and 3% for total SO(2). For the validation of the accuracy of the new method, the results are compared with those of reference methods. The agreement of the values for total SO(2) with values of the classic method is satisfactory: five out of six samples show deviations less than 16%. Due to the instability of free SO(2) in wine and the known problems of the used reference method, serious deviations of the free SO(2) results are found for three samples. The evaluation of the limits of detection focuses on the value for free SO(2), which is the sulfur form having by far the lowest concentration in wine. Here, the achievable limit of detection is 1.8 mg L(-1). [figure: see text] Detection of non-metal elements using continuum source flame absorption spectrometry.

  2. Including climate variability in determination of the optimum rate of N fertilizer application using a crop model: A case study for rainfed corn in eastern Canada (United States)

    Mesbah, M.; Pattey, E.; Jégo, G.; Geng, X.; Tremblay, N.; Didier, A.


    Identifying optimum nitrogen (N) application rate is essential for increasing agricultural production while limiting potential environmental contaminations caused by release of reactive N, especially for high demand N crops such as corn. The central question of N management is then how the optimum N rate is affected by climate variability for given soil. The experimental determination of optimum N rates involve the analyses of variance on the mean value of crop yield response to various N application rates used by factorial plot based experiments for a few years in several regions. This traditional approach has limitations to capture 1) the non-linear response of yield to N application rates due to large incremental N rates (often more than 40 kg N ha-1) and 2) the ecophysiological response of the crop to climate variability because of limited numbers of growing seasons considered. Modeling on the other hand, does not have such limitations and hence we use a crop model and propose a model-based methodology called Finding NEMO (N Ecophysiologically Modelled Optimum) to identify the optimum N rates for variable agro-climatic conditions and given soil properties. The performance of the methodology is illustrated using the STICS crop model adapted for rainfed corn in the Mixedwood Plains ecozone of eastern Canada (42.3oN 83oW-46.8oN 71oW) where more than 90% of Canadian corn is produced. The simulations were performed using small increment of preplant N application rate (10 kg N ha -1), long time series of daily climatic data (48 to 61 years) for 5 regions along the ecozone, and three contrasting soils per region. The results show that N recommendations should be region and soil specific. Soils with lower available water capacity required more N compared to soil with higher available water capacity. When N rates were at their ecophysiologically optimum level, 10 to 17 kg increase in dry yield could be achieved by adding 1 kg N. Expected yield also affected the optimum

  5. The Next Great Science (United States)

    Hodges, K. V.


    Earth science --- when defined as the study of all biological, chemical, and physical processes that interact to define the behavior of the Earth system --- has direct societal relevance equal to or greater than that any other branch of science. However, "geology", "geoscience", and "Earth science" departments are contracting at many universities and even disappearing at some. This irony speaks volumes about the limitations of the traditional university structure that partitions educational and research programs into specific disciplines, each housed in its own department. Programs that transcend disciplinary boundaries are difficult to fit into the traditional structure and are thus highly vulnerable to threats such as chronic underfunding by university administrations, low enrollments in more advanced subjects, and being largely forgotten during capital campaigns. Dramatic improvements in this situation will require a different way of thinking about earth science programs by university administrations. As Earth scientists, our goal must not be to protect "traditional" geology departments, but rather to achieve a sustainable programmatic future for broader academic programs that focus on Earth evolution from past, present, and future perspectives. The first step toward meeting this goal must be to promote a more holistic definition of Earth science that includes modes of inquiry more commonly found in engineering and social science departments. We must think of Earth science as a meta-discipline that includes core components of physics, geology, chemistry, biology, and the emerging science of complexity. We must recognize that new technologies play an increasingly important role in our ability to monitor global environmental change, and thus our educational programs must include basic training in the modes of analysis employed by engineers as well as those employed by scientists. One of the most important lessons we can learn from the engineering community is the

    Williams, Carl

    Measurements are the foundation for science and modern life. Technologies we take for granted every day depend on them-cell phones, CAT scans, pharmaceuticals, even sports equipment. Metrology, or measurement science, determines what industry can make reliably and what they cannot. At the National Institute of Standards and Technology (NIST) we specialize in making world class measurements that an incredibly wide range of industries use to continually improve their products - computer chips with nanoscale components, atomic clocks that you can hold in your hand, lasers for both super-strong welds and delicate eye surgeries. Think of all the key technologies developed over the last 100 years and better measurements, standards, or analysis techniques played a role in making them possible. NIST works collaboratively with industry researchers on the advanced metrology for tomorrow's technologies. A new kilogram based on electromagnetic force, cars that weigh half as much but are just as strong, quantum computers, personalized medicine, single atom devices - it's all happening in our labs now. This talk will focus on how metrology creates the future.

    CERN Document Server

    Davis, A


    The industry’s most outspoken and insightful critic explains how the software industry REALLY works. In Great Software Debates, Al Davis, shares what he has learned about the difference between the theory and the realities of business and encourages you to question and think about software engineering in ways that will help you succeed where others fail. In short, provocative essays, Davis fearlessly reveals the truth about process improvement, productivity, software quality, metrics, agile development, requirements documentation, modeling, software marketing and sales, empiricism, start-up financing, software research, requirements triage, software estimation, and entrepreneurship.

  14. Idiopathic great saphenous phlebosclerosis.

    Directory of Open Access Journals (Sweden)

    Ahmadreza Jodati


    Full Text Available Arterial sclerosis has been extensively described but reports on venous sclerosis are very sparse. Phlebosclerosis refers to the thickening and hardening of the venous wall. Despite its morphological similarities with arteriosclerosis and potential morbid consequences, phlebosclerosis has gained only little attention. We report a 72 year old male with paralysis and atrophy of the right leg due to childhood poliomyelitis who was referred for coronary artery bypass surgery. The great saphenous vein, harvested from the left leg, showed a hardened cord-like obliterated vein. Surprisingly, harvested veins from the atrophic limb were normal and successfully used for grafting.

  15. Early Holocene Great Salt Lake (United States)

    Oviatt, Charles G.; Madsen, David B.; Miller, David; Thompson, Robert S.; McGeehin, John P.


    Shorelines and surficial deposits (including buried forest-floor mats and organic-rich wetland sediments) show that Great Salt Lake did not rise higher than modern lake levels during the earliest Holocene (11.5–10.2 cal ka BP; 10–9 14C ka BP). During that period, finely laminated, organic-rich muds (sapropel) containing brine-shrimp cysts and pellets and interbedded sodium-sulfate salts were deposited on the lake floor. Sapropel deposition was probably caused by stratification of the water column — a freshwater cap possibly was formed by groundwater, which had been stored in upland aquifers during the immediately preceding late-Pleistocene deep-lake cycle (Lake Bonneville), and was actively discharging on the basin floor. A climate characterized by low precipitation and runoff, combined with local areas of groundwater discharge in piedmont settings, could explain the apparent conflict between evidence for a shallow lake (a dry climate) and previously published interpretations for a moist climate in the Great Salt Lake basin of the eastern Great Basin.

  16. Development of a Repeatable Protocol to Uniformly Coat Internal Complex Geometries of Fine Featured 3D Printed Objects with Ceramic Material, including Determination of Viscosity Limits to Properly Coat Certain Pore Sizes

    Energy Technology Data Exchange (ETDEWEB)

    Rogers, A. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)


    HEPA filters are commonly used in air filtration systems ranging in application from simple home systems to the more advanced networks used in research and development. Currently, these filters are most often composed of glass fibers with diameter on the order of one micron with polymer binders. These fibers, as well as the polymers used, are known to be fragile and can degrade or become extremely brittle with heat, severely limiting their use in high temperature applications. Ceramics are one promising alternative and can enhance the filtration capabilities compared to the current technology. Because ceramic materials are more thermally resistant and chemically stable, there is great interest in developing a repeatable protocol to uniformly coat fine featured polymer objects with ceramic material for use as a filter. The purpose of this experiment is to determine viscosity limits that are able to properly coat certain pore sizes in 3D printed objects, and additionally to characterize the coatings themselves. Latex paint was used as a surrogate because it is specifically designed to produce uniform coatings.

  11. Integrating Climate Change into Great Lakes Protection (United States)

    Hedman, S.


    Climate change is now recognized as one of the greatest threats to the Great Lakes. Projected climate change impacts to the Great Lakes include increases in surface water and air temperature; decreases in ice cover; shorter winters, early spring, and longer summers; increased frequency of intense storms; more precipitation falling as rain in the winter; less snowfall; and variations in water levels, among other effects. Changing climate conditions may compromise efforts to protect and restore the Great Lakes ecosystem and may lead to irrevocable impacts on the physical, chemical, and biological integrity of the Great Lakes. Examples of such potential impacts include the transformation of coastal wetlands into terrestrial ecosystems; reduced fisheries; increased beach erosion; change in forest species composition as species migrate northward; potential increase in toxic substance concentrations; potential increases in the frequency and extent of algal blooms; degraded water quality; and a potential increase in invasive species. The Great Lakes Restoration Initiative, signed into law by President Obama in 2010, represents the commitment of the federal government to protect, restore, and maintain the Great Lakes ecosystem. The GLRI Action Plan, issued in February 2010, identifies five focus areas: - Toxic Substances and Areas of Concern - Invasive Species - Nearshore Health and Nonpoint Source Pollution - Habitat and Wildlife Protection and Restoration - Accountability, Education, Monitoring, Evaluation, Communication, and Partnerships The Action Plan recognizes that the projected impacts of climate change on the Great Lakes have implications across all focus areas and encourages incorporation of climate change considerations into GLRI projects and programs as appropriate. Under the GLRI, EPA has funded climate change-related work by states, tribes, federal agencies, academics and NGOs through competitive grants, state and tribal capacity grants, and Interagency

  12. Climate variability and Great Plains agriculture

    International Nuclear Information System (INIS)

    Rosenberg, N.J.; Katz, L.A.


    The ways in which inhabitants of the Great Plains, including Indians, early settlers, and 20th century farmers, have adapted to climate changes on the Great Plains are explored. The climate of the Great Plains, because of its variability and extremes, can be very stressful to plants, animals and people. It is suggested that agriculture and society on the Great Plains have, during the last century, become less vulnerable to the stresses imposed by climate. Opinions as to the sustainability of agriculture on the Great Plains vary substantially. Lockeretz (1981) suggests that large scale, high cost technologies have stressed farmers by creating surpluses and by requiring large investments. Opie (1989) sees irrigation as a climate substitute, however he stresses that the Ogallala aquifer must inevitably become depleted. Deborah and Frank Popper (1987) believe that farming on the Plains is unsustainable, and destruction of shelterbelts, out-migration of the rural population and environmental problems will lead to total collapse. With global warming, water in the Great Plains is expected to become scarcer, and although improvements in irrigation efficiency may slow depletion of the Ogallala aquifer, ultimately the acreage under irrigation must decrease to levels that can be sustained by natural recharge and reliable surface flows. 23 refs., 2 figs

  13. Ecosystem services in the Great Lakes (United States)

    Steinman, Alan D.; Cardinale, Bradley J; Munns Jr, Wayne R; Ogdahl, Mary E.; Allan, David J; Angadi, Ted; Bartlett, Sarah; Brauman, Kate; Byappanahalli, Muruleedhara; Doss, Matt; Dupont, Diane; Johns, Annie; Kashian, Donna; Lupi, Frank; McIntyre, Peter B.; Miller, Todd; Moore, Michael P.; Muenich, Rebecca Logsdon; Poudel, Rajendra; Price, James; Provencher, Bill; Rea, Anne; Read, Jennifer; Renzetti, Steven; Sohngen, Brent; Washburn, Erica


    A comprehensive inventory of ecosystem services across the entire Great Lakes basin is currently lacking and is needed to make informed management decisions. A greater appreciation and understanding of ecosystem services, including both use and non-use services, may have avoided misguided resource management decisions in the past that resulted in negative legacies inherited by future generations. Given the interest in ecosystem services and lack of a coherent approach to addressing this topic in the Great Lakes, a summit was convened involving 28 experts working on various aspects of ecosystem services in the Great Lakes. The invited attendees spanned a variety of social and natural sciences. Given the unique status of the Great Lakes as the world's largest collective repository of surface freshwater, and the numerous stressors threatening this valuable resource, timing was propitious to examine ecosystem services. Several themes and recommendations emerged from the summit. There was general consensus that: 1) a comprehensive inventory of ecosystem services throughout the Great Lakes is a desirable goal but would require considerable resources; 2) more spatially and temporally intensive data are needed to overcome our data gaps, but the arrangement of data networks and observatories must be well-coordinated; 3) trade-offs must be considered as part of ecosystem services analyses; and 4) formation of a Great Lakes Institute for Ecosystem Services, to provide a hub for research, meetings, and training is desirable. Several challenges also emerged during the summit, which are discussed.

  16. Great Lakes rivermouths: a primer for managers (United States)

    Pebbles, Victoria; Larson, James; Seelbach, Paul; Pebbles, Victoria; Larson, James; Seelbach, Paul


    Between the North American Great Lakes and their tributaries are the places where the confluence of river and lake waters creates a distinct ecosystem: the rivermouth ecosystem. Human development has often centered around these rivermouths, in part, because they provide a rich array of ecosystem services. Not surprisingly, centuries of intense human activity have led to substantial pressures on, and alterations to, these ecosystems, often diminishing or degrading their ecological functions and associated ecological services. Many Great Lakes rivermouths are the focus of intense restoration efforts. For example, 36 of the active Great Lakes Areas of Concern (AOCs) are rivermouths or areas that include one or more rivermouths. Historically, research of rivermouth ecosystems has been piecemeal, focused on the Great Lakes proper or on the upper reaches of tributaries, with little direct study of the rivermouth itself. Researchers have been divided among disciplines, agencies and institutions; and they often work independently and use disparate venues to communicate their work. Management has also been fragmented with a focus on smaller, localized, sub-habitat units and socio-political or economic elements, rather than system-level consideration. This Primer presents the case for a more holistic approach to rivermouth science and management that can enable restoration of ecosystem services with multiple benefits to humans and the Great Lakes ecosystem. A conceptual model is presented with supporting text that describes the structures and processes common to all rivermouths, substantiating the case for treating these ecosystems as an identifiable class.1 Ecological services provided by rivermouths and changes in how humans value those services over time are illustrated through case studies of two Great Lakes rivermouths—the St. Louis River and the Maumee River. Specific ecosystem services are identified in italics throughout this Primer and follow definitions described

  17. Experimental Determination of the Recovery Factor and Analytical Solution of the Conical Flow Field for a 20 deg Included Angle Cone at Mach Numbers of 4.6 and 6.0 and Stagnation Temperatures to 2600 degree R (United States)

    Pfyl, Frank A.; Presley, Leroy L.


    The local recovery factor was determined experimentally along the surface of a thin-walled 20 deg included angle cone for Mach numbers near 6.0 at stagnation temperatures between 1200 deg R and 2600 deg R. In addition, a similar cone configuration was tested at Mach numbers near 4.5 at stagnation temperatures of approximately 612 deg R. The local Reynolds number based on flow properties at the edge of the boundary layer ranged between 0.1 x 10(exp 4) and 3.5 x 10(exp 4) for tests at temperatures above 1200 deg R and between 6 x 10(exp 4) and 25 x 10(exp 4) for tests at temperatures near 612 deg R. The results indicated, generally, that the recovery factor can be predicted satisfactorily using the square root of the Prandtl number. No conclusion could be made as to the necessity of evaluating the Prandtl number at a reference temperature given by an empirical equation, as opposed to evaluating the Prandtl number at the wall temperature or static temperature of the gas at the cone surface. For the tests at temperatures above 1200 deg R (indicated herein as the tests conducted in the slip-flow region), two definite trends in the recovery data were observed - one of increasing recovery factor with decreasing stagnation pressure, which was associated with slip-flow effects and one of decreasing recovery factor with increasing temperature. The true cause of the latter trend could not be ascertained, but it was shown that this trend was not appreciably altered by the sources of error of the magnitude considered herein. The real-gas equations of state were used to determine accurately the local stream properties at the outer edge of the boundary layer of the cone. Included in the report, therefore, is a general solution for the conical flow of a real gas using the Beattie-Bridgeman equation of state. The largest effect of temperature was seen to be in the terms which were dependent upon the internal energy of the gas. The pressure and hence the pressure drag terms were

  18. Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory; determination of 86 volatile organic compounds in water by gas chromatography/mass spectrometry, including detections less than reporting limits (United States)

    Connor, Brooke F.; Rose, Donna L.; Noriega, Mary C.; Murtaugh, Lucinda K.; Abney, Sonja R.


    This report presents precision and accuracy data for volatile organic compounds (VOCs) in the nanogram-per-liter range, including aromatic hydrocarbons, reformulated fuel components, and halogenated hydrocarbons using purge and trap capillary-column gas chromatography/mass spectrometry. One-hundred-four VOCs were initially tested. Of these, 86 are suitable for determination by this method. Selected data are provided for the 18 VOCs that were not included. This method also allows for the reporting of semiquantitative results for tentatively identified VOCs not included in the list of method compounds. Method detection limits, method performance data, preservation study results, and blank results are presented. The authors describe a procedure for reporting low-concentration detections at less than the reporting limit. The nondetection value (NDV) is introduced as a statistically defined reporting limit designed to limit false positives and false negatives to less than 1 percent. Nondetections of method compounds are reported as ?less than NDV.? Positive detections measured at less than NDV are reported as estimated concentrations to alert the data user to decreased confidence in accurate quantitation. Instructions are provided for analysts to report data at less than the reporting limits. This method can support the use of either method reporting limits that censor detections at lower concentrations or the use of NDVs as reporting limits. The data-reporting strategy for providing analytical results at less than the reporting limit is a result of the increased need to identify the presence or absence of environmental contaminants in water samples at increasingly lower concentrations. Long-term method detection limits (LTMDLs) for 86 selected compounds range from 0.013 to 2.452 micrograms per liter (?g/L) and differ from standard method detection limits (MDLs) in that the LTMDLs include the long-term variance of multiple instruments, multiple operators, and multiple

  7. The Great London Smog of 1952. (United States)

    Polivka, Barbara J


    : The Great London Smog of December 1952 lasted five days and killed up to 12,000 people. The smog developed primarily because of extensive burning of high-sulfur coal. The health effects were both immediate and long lasting, with a recent study revealing an increased likelihood of childhood asthma development in those exposed to the Great Smog while in utero or during their first year of life. Subsequent pollution legislation-including the U.S. Clean Air Act and its amendments-have demonstrably reduced air pollution and positively impacted health outcomes. With poor air quality events like the Great Smog continuing to occur today, nurses need to be aware of the impact such environmental disasters can have on human health.

  10. Great East Japan Earthquake Tsunami (United States)

    Iijima, Y.; Minoura, K.; Hirano, S.; Yamada, T.


    The 11 March 2011, Mw 9.0 Great East Japan Earthquake, already among the most destructive earthquakes in modern history, emanated from a fault rupture that extended an estimated 500 km along the Pacific coast of Honshu. This earthquake is the fourth among five of the strongest temblors since AD 1900 and the largest in Japan since modern instrumental recordings began 130 years ago. The earthquake triggered a huge tsunami, which invaded the seaside areas of the Pacific coast of East Japan, causing devastating damages on the coast. Artificial structures were destroyed and planted forests were thoroughly eroded. Inrush of turbulent flows washed backshore areas and dunes. Coastal materials including beach sand were transported onto inland areas by going-up currents. Just after the occurrence of the tsunami, we started field investigation of measuring thickness and distribution of sediment layers by the tsunami and the inundation depth of water in Sendai plain. Ripple marks showing direction of sediment transport were the important object of observation. We used a soil auger for collecting sediments in the field, and sediment samples were submitted for analyzing grain size and interstitial water chemistry. Satellite images and aerial photographs are very useful for estimating the hydrogeological effects of tsunami inundation. We checked the correspondence of micro-topography, vegetation and sediment covering between before and after the tsunami. The most conspicuous phenomenon is the damage of pine forests planted in the purpose of preventing sand shifting. About ninety-five percent of vegetation coverage was lost during the period of rapid currents changed from first wave. The landward slopes of seawalls were mostly damaged and destroyed. Some aerial photographs leave detailed records of wave destruction just behind seawalls, which shows the occurrence of supercritical flows. The large-scale erosion of backshore behind seawalls is interpreted to have been caused by

    Castela Eduardo


    Full Text Available Abstract Transposition of the great arteries (TGA, also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA discordance. The incidence is estimated at 1 in 3,500–5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is associated with noncardiac malformations. The association with other cardiac malformations such as ventricular septal defect (VSD and left ventricular outflow tract obstruction is frequent and dictates timing and clinical presentation, which consists of cyanosis with or without congestive heart failure. The onset and severity depend on anatomical and functional variants that influence the degree of mixing between the two circulations. If no obstructive lesions are present and there is a large VSD, cyanosis may go undetected and only be perceived during episodes of crying or agitation. In these cases, signs of congestive heart failure prevail. The exact aetiology remains unknown. Some associated risk factors (gestational diabetes mellitus, maternal exposure to rodenticides and herbicides, maternal use of antiepileptic drugs have been postulated. Mutations in growth differentiation factor-1 gene, the thyroid hormone receptor-associated protein-2 gene and the gene encoding the cryptic protein have been shown implicated in discordant VA connections, but they explain only a small minority of TGA cases. The diagnosis is confirmed by echocardiography, which also provides the morphological details required for future surgical management. Prenatal diagnosis by foetal echocardiography is possible and desirable, as it may improve the early neonatal management and reduce morbidity and mortality. Differential diagnosis includes other causes of central neonatal cyanosis. Palliative treatment with prostaglandin E1 and balloon atrial septostomy are usually

    Cagan, A.; Theunert, C.; Laayouni, H.; Santpere, G.; Pybus, M.; Casals, F.; Prüfer, K.; Navarro, A.; Marques-Bonet, T.; Bertranpetit, J.; Andrés, A.


    Natural selection is crucial for the adaptation of populations to their environments. Here, we present the first global study of natural selection in the Hominidae (humans and great apes) based on genome-wide information from population samples representing all extant species (including most subspecies). Combining several neutrality tests we create a multi-species map of signatures of natural selection covering all major types of natural selection. We find that the estimated efficiency of bot...

    Full Text Available Rajiv K Chander,1 Thomas S Monahan1,2 1Section of Vascular Surgery, Department of Surgery, University of Maryland School of Medicine, 2Department of Surgery, Baltimore Veterans Affairs Medical Center, Baltimore, MD, USA Abstract: Duplex ultrasonography is the ideal modality to assess great saphenous vein insufficiency. Duplex ultrasonography incorporates both gray scale images to delineate anatomy and color-Doppler imaging that visualizes the flow of blood in a structure. Assessment of great saphenous vein requires definition of the anatomy, augmentation of flow, evaluation for both superficial and deep vein thrombosis, and determining the presence of reflux. Currently, evolution in the treatment of reflux also relies on ultrasound for the treatment of the disease. Understanding the utilization of the ultrasound for the diagnosis and treatment of greater saphenous vein reflux is important for practitioners treating reflux disease.

    resistance genes, including qnrA, qnrB, qnrS, and aac(6')Ib-cr, were selected. Disk diffusion assays and MIC determinations by the agar dilution method were performed, according to CLSI standards, with nalidixic acid, flumequine, oxolinic acid, ciprofloxacin, enrofloxacin, marbofloxacin, norfloxacin...... diffusion assay was not efficient for the detection of some of the isolates carrying qnr and aac(6')Ib-cr. Transferable resistance genes would best be detected by testing for the MIC of ciprofloxacin or norfloxacin, as testing for the MICs of the other compounds would fail to detect isolates carrying aac(6...... would be maximized by screening with either ciprofloxacin or norfloxacin by both MIC determination and disk diffusion assays. Furthermore, a low concentration of ciprofloxacin (1 microg) in the disks seemed to increase the sensitivity of the disk diffusion assay....

  2. Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory; determination of the total phosphorus by a Kjeldahl digestion method and an automated colorimetric finish that includes dialysis (United States)

    Patton, Charles J.; Truitt, Earl P.


    A method to determine total phosphorus (TP) in the same digests prepared for total Kjeldahl nitrogen (TKN) determinations is desribed. The batch, high-temperature (block digester), HG(II)-catalyzed digestion step is similar to U.S. Geological Survey methods I-2552-85/I-4552-85 and U.S. Environmental Protection Agency method 365.4 except that sample and reagent volumes are halved. Prepared digests are desolvated at 220 degrees Celsius and digested at 370 degrees Celsius in separate block digesters set at these temperatures, rather than in a single, temperature-programmed block digester. This approach is used in the method escribed here, which permits 40 calibrants, reference waters, and smaples to be digested and resolvated in about an hour. Orthophosphate ions originally present in samples, along with those released during the digestion step, are determined colorimetrically at a rate of 90 tests per hour by an automated version of the phosphoantimonylmolybdenum blue procedure. About 100 microliters of digest are required per determination. The upper concentration limit is 2 milligrams per liter (mg/L) with a method detection limt of 0.01 mg/L. Repeatability for a sample containing approximately 1.6 mg/L of TP in a high suspended-solids matrix is 0.7 percent. Between-day precision for the same sample is 5.0 percent. A dialyzer in the air-segmented continuous flow analyzer provides on-line digest cleanup, eliminated particulates that otherwise would interfere in the colorimetric finish. An single-channel analyzer can process the resolvated digests from two pairs of block digesters each hour. Paired t-test analysis of TP concentrations for approximately 1,600 samples determined by the new method (U.S. Geologial Survey methods I-2610-91 and I-4610-91) and the old method (U.S. Geological Survey methods I-2600-85 and I-4600-85) revealed positive bias in the former of 0.02 to 0.04 mg/L for surface-water samples in agreement with previous studies. Concentrations of total

  5. Double positivity to bee and wasp venom: improved diagnostic procedure by recombinant allergen-based IgE testing and basophil activation test including data about cross-reactive carbohydrate determinants. (United States)

    Eberlein, Bernadette; Krischan, Lilian; Darsow, Ulf; Ollert, Markus; Ring, Johannes


    Specific IgE (sIgE) antibodies to both bee and wasp venom can be due to a sensitivity to both insect venoms or due to cross-reactive carbohydrate determinants (CCDs). Investigating whether a basophil activation test (BAT) with both venoms as well as with bromelain and horseradish peroxidase (HRP) or recombinant allergen-based IgE testing can improve the diagnostic procedure. Twenty-two Hymenoptera-venom allergic patients with sIgE antibodies to both bee and wasp venom were studied. sIgE antibodies to MUXF3 CCD, bromelain, HRP, rApi m 1, and rVes v 5 were determined, and a BAT (Flow2 CAST) with venom extracts, bromelain, and HRP was performed. Further recombinant allergen-based IgE testing was done by using an ELISA, if required. The reactivity of basophils was calculated from the insect venom concentration at half-maximum stimulation. Double positivity/double negativity/single positivity to rApi m 1 and rVes v 5 was seen in 12/1/9 patients. Further recombinant allergen-based IgE testing in the last ones revealed positive results to the other venom in all cases except one. BAT was double positive/double negative/single positive in 6/2/14 patients. Four patients with negative results in sIgE antibodies to CCDs had positive results in BAT. BAT with bromelain/HRP showed a sensitivity of 50%/81% and a specificity of 91%/90%. Component-resolved IgE testing elucidates the pattern of double positivity, showing a majority of true double sensitizations independent of CCD sensitization. BAT seems to add more information about the culprit insect even if the true clinical relevance of BAT is not completely determined because of ethical limitations on diagnostic sting challenges. BAT with HRP is a good method to determine sensitivity to CCDs. Copyright © 2012 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

    Piotr Pietrow


    Full Text Available The rules of monasticism were collected and published in a single work entitled Asketikon by Saint Basil the Great. It is arranged in the form of questions and answers to create one coherent work. It has two different publications.The first publication named The Small Asketikon dates to 370-370. It is the fruit of the Saint’s work among Pontic communities and consists of 203 questions and answers. The orignial Greek manuscript has not survived and it is available only in two translations: the Latin Rufin and fragments in Syrian language. The second publication named The Great Asketikon appeard in about 377 and presents the most mature step of cenobitic monasticismin Basil’s elaboration. The Great Asketikon was created by adding new questions to The Small Asketikon and consists of two parts called the The Longer Rules and The Shorter Rules. The Longer Rules are primarily a set of questions and answers. It includes a wide range of rules and norms of the overall life in community. It refers to the fundamental rules of spirituality, such as love, sacrifice, obedience and rudimental problems connected withcommunity organization, cenobitic monasticism and the role of the superior, work and prayer. The second part of The Great Asketikon consists of shorter rules. Two publications are known: the first one originated in Pont andincludes 286 questions and answers and second arose in Cezarei and includes 318 questions and answers. In this work, the Hierarch explains in detail issues regarding community life and solves difficult problems connected with conscience. He writes about behavior towards brothers and explains the significance of weaknesses and virtues.

  8. Network Interactions in the Great Altai Region

    Directory of Open Access Journals (Sweden)

    Lev Aleksandrovich Korshunov


    Full Text Available To improve the efficiency and competitiveness of the regional economy, an effective interaction between educational institutions in the Great Altai region is needed. The innovation growth can enhancing this interaction. The article explores the state of network structures in the economy and higher education in the border territories of the countries of Great Altai. The authors propose an updated approach to the three-level classification of network interaction. We analyze growing influence of the countries with emerging economies. We define the factors that impede the more stable and multifaceted regional development of these countries. Further, the authors determine indicators of the higher education systems and cooperation systems at the university level between the Shanghai Cooperation Organization countries (SCO and BRICS countries, showing the international rankings of the universities in these countries. The teaching language is important to overcome the obstacles in the interregional cooperation. The authors specify the problems of the development of the universities of the SCO and BRICS countries as global educational networks. The research applies basic scientific logical methods of analysis and synthesis, induction and deduction, as well as the SWOT analysis method. We have indentified and analyzed the existing economic and educational relations. To promote the economic innovation development of the border territories of the Great Altai, we propose a model of regional network university. Modern universities function in a new economic environment. Thus, in a great extent, they form the technological and social aspects of this environment. Innovative network structures contribute to the formation of a new network institutional environment of the regional economy, which impacts the macro- and microeconomic performance of the region as a whole. The results of the research can help to optimize the regional economies of the border

    Battersby, Cameron


    The cause of the death of the Macedonian King, Alexander the Great, at Babylon in 323 BC has excited interest and conjecture throughout the ages. The information available in the surviving ancient sources, none of which is contemporaneous, has been reviewed and compared with modern knowledge as set out in several well-known recent surgical texts. The ancient sources record epic drinking by the Macedonian nobility since at least the time of Phillip II, Alexander's father. Alexander's sudden illness and death is likely to have resulted from a surgical complication of acute alcoholic excess.

    Cardiovascular disease is the leading cause of mortality worldwide. We have made large strides over the past few decades in management, but definitive therapeutic options to address this health-care burden are still limited. Given the ever-increasing need, much effort has been spent creating engineered tissue to replaced diseased tissue. This article gives a general overview of this work as it pertains to the development of great vessels, myocardium, and heart valves. In each area, we focus on currently studied methods, limitations, and areas for future study. PMID:28289246

  13. Beach science in the Great Lakes (United States)

    Nevers, Meredith B.; Byappanahalli, Murulee N.; Edge, Thomas A.; Whitman, Richard L.


    Monitoring beach waters for human health has led to an increase and evolution of science in the Great Lakes, which includes microbiology, limnology, hydrology, meteorology, epidemiology, and metagenomics, among others. In recent years, concerns over the accuracy of water quality standards at protecting human health have led to a significant interest in understanding the risk associated with water contact in both freshwater and marine environments. Historically, surface waters have been monitored for fecal indicator bacteria (fecal coliforms, Escherichia coli, enterococci), but shortcomings of the analytical test (lengthy assay) have resulted in a re-focusing of scientific efforts to improve public health protection. Research has led to the discovery of widespread populations of fecal indicator bacteria present in natural habitats such as soils, beach sand, and stranded algae. Microbial source tracking has been used to identify the source of these bacteria and subsequently assess their impact on human health. As a result of many findings, attempts have been made to improve monitoring efficiency and efficacy with the use of empirical predictive models and molecular rapid tests. All along, beach managers have actively incorporated new findings into their monitoring programs. With the abundance of research conducted and information gained over the last 25 years, “Beach Science” has emerged, and the Great Lakes have been a focal point for much of the ground-breaking work. Here, we review the accumulated research on microbiological water quality of Great Lakes beaches and provide a historic context to the collaborative efforts that have advanced this emerging science.

    To critically evaluate the clinical implications of the use of non-fasting rather than fasting lipid profiles and to provide guidance for the laboratory reporting of abnormal non-fasting or fasting lipid profiles. Extensive observational data, in which random non-fasting lipid profiles have been compared with those determined under fasting conditions, indicate that the maximal mean changes at 1-6 h after habitual meals are not clinically significant [+0.3 mmol/L (26 mg/dL) for triglycerides; -0.2 mmol/L (8 mg/dL) for total cholesterol; -0.2 mmol/L (8 mg/dL) for LDL cholesterol; +0.2 mmol/L (8 mg/dL) for calculated remnant cholesterol; -0.2 mmol/L (8 mg/dL) for calculated non-HDL cholesterol]; concentrations of HDL cholesterol, apolipoprotein A1, apolipoprotein B, and lipoprotein(a) are not affected by fasting/non-fasting status. In addition, non-fasting and fasting concentrations vary similarly over time and are comparable in the prediction of cardiovascular disease. To improve patient compliance with lipid testing, we therefore recommend the routine use of non-fasting lipid profiles, whereas fasting sampling may be considered when non-fasting triglycerides are >5 mmol/L (440 mg/dL). For non-fasting samples, laboratory reports should flag abnormal concentrations as triglycerides ≥2 mmol/L (175 mg/dL), total cholesterol ≥5 mmol/L (190 mg/dL), LDL cholesterol ≥3 mmol/L (115 mg/dL), calculated remnant cholesterol ≥0.9 mmol/L (35 mg/dL), calculated non-HDL cholesterol ≥3.9 mmol/L (150 mg/dL), HDL cholesterol ≤1 mmol/L (40 mg/dL), apolipoprotein A1 ≤1.25 g/L (125 mg/dL), apolipoprotein B ≥1.0 g/L (100 mg/dL), and lipoprotein(a) ≥50 mg/dL (80th percentile); for fasting samples, abnormal concentrations correspond to triglycerides ≥1.7 mmol/L (150 mg/dL). Life-threatening concentrations require separate referral for the risk of pancreatitis when triglycerides are >10 mmol/L (880 mg/dL), for homozygous familial hypercholesterolemia when LDL cholesterol

    The 'Great Hedge of India', a 3 700 kilometre-long hedge installed by the British customs to safeguard the colonial salt tax system and avoid salt smuggling totally faded from both memory and records (e.g. maps) in less than a century. Roy Moxham found traces of the hedge in a book footnote and searched it for several years until he found its meagre remains. The speaker wrote a book about this quest. He said that this story reveals how things disappear when they are no longer useful and, especially, when they are linked to parts of history that are not deemed particularly positive (the hedge was a means of colonial power)

  18. The Great Warming Brian Fagan (United States)

    Fagan, B. M.


    The Great Warming is a journey back to the world of a thousand years ago, to the Medieval Warm Period. Five centuries of irregular warming from 800 to 1250 had beneficial effects in Europe and the North Atlantic, but brought prolonged droughts to much of the Americas and lands affected by the South Asian monsoon. The book describes these impacts of warming on medieval European societies, as well as the Norse and the Inuit of the far north, then analyzes the impact of harsh, lengthy droughts on hunting societies in western North America and the Ancestral Pueblo farmers of Chaco Canyon, New Mexico. These peoples reacted to drought by relocating entire communities. The Maya civilization was much more vulnerable that small-scale hunter-gatherer societies and subsistence farmers in North America. Maya rulers created huge water storage facilities, but their civilization partially collapsed under the stress of repeated multiyear droughts, while the Chimu lords of coastal Peru adapted with sophisticated irrigation works. The climatic villain was prolonged, cool La Niñalike conditions in the Pacific, which caused droughts from Venezuela to East Asia, and as far west as East Africa. The Great Warming argues that the warm centuries brought savage drought to much of humanity, from China to Peru. It also argues that drought is one of the most dangerous elements in today’s humanly created global warming, often ignored by preoccupied commentators, but with the potential to cause over a billion people to starve. Finally, I use the book to discuss the issues and problems of communicating multidisciplinary science to the general public.

  20. The Great Recession, unemployment and suicide. (United States)

    Norström, Thor; Grönqvist, Hans


    How have suicide rates responded to the marked increase in unemployment spurred by the Great Recession? Our paper puts this issue into a wider perspective by assessing (1) whether the unemployment-suicide link is modified by the degree of unemployment protection, and (2) whether the effect on suicide of the present crisis differs from the effects of previous economic downturns. We analysed the unemployment-suicide link using time-series data for 30 countries spanning the period 1960-2012. Separate fixed-effects models were estimated for each of five welfare state regimes with different levels of unemployment protection (Eastern, Southern, Anglo-Saxon, Bismarckian and Scandinavian). We included an interaction term to capture the possible excess effect of unemployment during the Great Recession. The largest unemployment increases occurred in the welfare state regimes with the least generous unemployment protection. The unemployment effect on male suicides was statistically significant in all welfare regimes, except the Scandinavian one. The effect on female suicides was significant only in the eastern European country group. There was a significant gradient in the effects, being stronger the less generous the unemployment protection. The interaction term capturing the possible excess effect of unemployment during the financial crisis was not significant. Our findings suggest that the more generous the unemployment protection the weaker the detrimental impact on suicide of the increasing unemployment during the Great Recession.

  1. Hummingbirds have a greatly enlarged hippocampal formation. (United States)

    Ward, Brian J; Day, Lainy B; Wilkening, Steven R; Wylie, Douglas R; Saucier, Deborah M; Iwaniuk, Andrew N


    Both field and laboratory studies demonstrate that hummingbirds (Apodiformes, Trochilidae) have exceptional spatial memory. The complexity of spatial-temporal information that hummingbirds must retain and use daily is probably subserved by the hippocampal formation (HF), and therefore, hummingbirds should have a greatly expanded HF. Here, we compare the relative size of the HF in several hummingbird species with that of other birds. Our analyses reveal that the HF in hummingbirds is significantly larger, relative to telencephalic volume, than any bird examined to date. When expressed as a percentage of telencephalic volume, the hummingbird HF is two to five times larger than that of caching and non-caching songbirds, seabirds and woodpeckers. This HF expansion in hummingbirds probably underlies their ability to remember the location, distribution and nectar content of flowers, but more detailed analyses are required to determine the extent to which this arises from an expansion of HF or a decrease in size of other brain regions.

  3. Cholera: a great global concern. (United States)

    Mandal, Shyamapada; Mandal, Manisha Deb; Pal, Nishith Kumar


    Cholera, caused by the infection of toxigenic Vibrio cholerae (V. cholerae) to humans, is a life threatening diarrheal disease with epidemic and pandemic potential. The V. cholerae, both O1 and O139 serogroups, produce a potent enterotoxin (cholera toxin) responsible for the lethal symptoms of the disease. The O1 serogroup has two biotypes (phenotypes), classical and El Tor; each of which has two major serotypes (based on antigenic responses), Ogawa and Inaba and the extremely rare Hikojima. V. cholerae O1 strains interconvert and switch between the Ogawa and Inaba serotypes. Fluid and electrolyte replacement is the mainstay of treatment of cholera patients; the severe cases require antibiotic treatment to reduce the duration of illness and replacement of fluid intake. The antibiotic therapy currently has faced difficulties due to the rapid emergence and spread of multidrug resistant V. cholerae causing several outbreaks in the globe. Currently, cholera has been becoming endemic in an increasing number of geographical areas, reflecting a failure in implementation of control measures. However, the current safe oral vaccines lower the number of resistant infections and could thus represent an effective intervention measure to control antibiotic resistance in cholera. Overall, the priorities for cholera control remain public health interventions through improved drinking water, sanitation, surveillance and access to health care facilities, and further development of safe, effective and appropriate vaccines. Thus, this review describes the facts and phenomena related to the disease cholera, which is still a great threat mainly to the developing countries, and hence a grave global concern too.

  4. Potential Impacts of Climate Change in the Great Lakes Region (United States)

    Winkler, J. A.


    Climate change is projected to have substantial impacts in the Great Lakes region of the United States. One intent of this presentation is to introduce the Great Lakes Integrated Sciences and Assessments Center (GLISA), a recently-funded NOAA RISA center. The goals and unique organizational structure of GLISA will be described along with core activities that support impact and assessment studies in the region. Additionally, observed trends in temperature, precipitation including lake effect snowfall, and lake temperatures and ice cover will be summarized for the Great Lakes region, and vulnerabilities to, and potential impacts of, climate change will be surveyed for critical natural and human systems. These include forest ecosystems, water resources, traditional and specialized agriculture, and tourism/recreation. Impacts and vulnerabilities unique to the Great Lakes region are emphasized.

  5. China in space the great leap forward

    CERN Document Server

    Harvey, Brian


    The 21st century has seen the emergence, after the Soviet Union and the United States, of the third great space superpower: China. Here, in China in Space - The Great Leap Forward, Brian Harvey takes a contemporary look at the new Chinese space program. China has already launched its first space station, Tiangong; has sent its first spacecraft to the Moon, the Chang e; and has plans to send spaceships to Mars and further afield. China's annual launch rate has already overtaken those of both Europe and the United States. Huge new production plants and launch centers are under construction, to build and launch the new family of Long March 5, 6, and 7 rockets. In Roadmap 2050, the Academy of Sciences indicates that China intends to be the leading spacefaring nation by mid-century, with bases on the Moon and Mars. This book gives an informed, fully up-to-date commentary on all aspects of the Chinese space program, including its history, development, technology, missions, and the personalities involved. It lists a...

  6. The effect of the United States Great Lakes on the maintenance of derecho-producing mesoscale convective systems. (United States)

    Bentley, M.; Sparks, J.; Graham, R.


    The primary aim of this research is to investigate the influence of the United States Great Lakes on the intensity of mesoscale convective systems (MCSs). One of the greatest nowcast challenges during the warm season is anticipating the impact of the Great Lakes on severe convection, particularly MCSs capable of producing damaging widespread windstorms known as derechos. Since a major derecho activity corridor lies over the Great Lakes region, it is important to understand the effects of the Lakes on the intensity and propagation of severe wind producing MCSs. Specific objectives of the research include: 1) The development of a short-term climatology of MCS events that have impacted the Great Lakes region over the past seven years; 2) An analysis of radar, satellite, surface (including buoy and lighthouse observations), and lake surface temperature data to determine the environmental conditions impacting the evolution of MCSs passing over a Great Lake; 3) An examination of MCS initiation times and seasonal frequencies of occurrence to delineate temporal consistencies in MCS evolution due to changing lake surface temperatures; and 4) The development of conceptual and forecast models to help anticipate MCS intensity and morphology as these systems interact with the Great Lakes environment.

  9. Dipole vortices in the Great Australian Bight

    DEFF Research Database (Denmark)

    Cresswell, George R.; Lund-Hansen, Lars C.; Nielsen, Morten Holtegaard


    Shipboard measurements from late 2006 made by the Danish Galathea 3 Expedition and satellite sea surface temperature images revealed a chain of cool and warm mushroom' dipole vortices that mixed warm, salty, oxygen-poor waters on and near the continental shelf of the Great Australian Bight (GAB......) with cooler, fresher, oxygen-rich waters offshore. The alternating jets' flowing into the mushrooms were directed mainly northwards and southwards and differed in temperature by only 1.5 degrees C; however, the salinity difference was as much as 0.5, and therefore quite large. The GAB waters were slightly...... denser than the cooler offshore waters. The field of dipoles evolved and distorted, but appeared to drift westwards at 5km day-1 over two weeks, and one new mushroom carried GAB water southwards at 7km day(-1). Other features encountered between Cape Leeuwin and Tasmania included the Leeuwin Current...

  10. Unpacking the great transmission debate (United States)

    Denning, Kathryn


    The debate about the wisdom of sending interstellar transmissions is well-known to those involved in SETI, and frustrating for many. Its tendency towards intractability is a result of multiple factors, including: different models of the scientist's role as citizen and/or leader; disparate ideas about society's readiness to cope with frontier science; variable political substrates, particularly ideas concerning individual freedom and state control; competing ideologies of globalization; and the perceived relative risks and benefits of contact. (Variations in the latter, i.e. assessments of the risks and benefits of contact, derive partly from different thinking styles, including tolerance for risk, and partly from inferences based upon episodes of biological and cultural contact on Earth.) Unpacking the debate into its components may be of use to those debating policy about SETI transmissions, or at the very least, help keep in focus what, precisely, the perennial arguments are really about.

  11. Behind every great detector, there are lots of great people!

    CERN Multimedia

    Pauline Gagnon

    Remember all these pictures you sent out last year for a poster project? At last, after a few unsuccessful attempts, the "ATLAS People poster" is out. This mosaic picture was built out of the 600 or so photos collected for the poster, including the 120 or so portraits taken by Claudia Marcelloni di Oliveira. Each photo appears roughly 15 times to fill the 9000 pixels of the poster. Sorry: there is no key to help you locate your photo but you can buy a copy of the poster at the ATLAS secretariat to stare at it as much as you like. They are on sale for only 4 CHF (or 3 CHF a piece for 10 or more copies). I hope many of you will display it in your office and at your home institute to give a sense of the size of the human effort involved to build this experiment and make it a bit less anonymous.

    Horrill, A.D.; Lowe, V.P.W.; Howson, G.


    Chernobyl deposition in the UK was sampled in May and October 1986 and in June of 1987. The sampling concentrated on grassy vegetation but in October 1986 other vegetation, soils and wildlife were included. Deposition patterns have been established and a greater degree of retention and recycling indicated for the organic soils of upland Britain. For wild animals concentration factors varied not only between species but with sex and age. Highest tissue concentrations were recorded in species feeding on heather (Blue hares and Grouse) and the lowest in rabbits feeding on grass over mineral soils. Radiocaesium was found in a carnivore (the fox) at the top of the food chain. (author)

  13. Vegetation baseline report : Connacher great divide project

    Energy Technology Data Exchange (ETDEWEB)



    This baseline report supported an application by Connacher Oil and Gas Ltd. to the Alberta Energy and Utilities Board (EUB) and Alberta Environment (AENV) for the Great Divide Steam Assisted Gravity Drainage (SAGD) Project. The goal of the report was to document the distribution and occurrence of ecosite phases and wetland classes in the project footprint as well as to document the distribution of rare plants; rare plant communities: and intrusive species and old growth communities, including species of management concern. A methodology of the baseline report was presented, including details of mapping and field surveys. Six vegetation types in addition to the disturbed land unit were identified in the project footprint and associated buffer. It was noted that all vegetation types are common for the boreal forest natural regions. Several species of management concern were identified during the spring rare plant survey, including rare bryophytes and non-native or invasive species. Mitigation was identified through a slight shift of the footprint, transplant of appropriate bryophyte species and implementation of a weed management plan. It was noted that results of future surveys for rare plants will be submitted upon completion. It was concluded that the effects of the project on existing vegetation is expected to be low because of the small footprint, prior disturbance history, available mitigation measures and conservation and reclamation planning. 27 refs., 5 tabs., 4 figs.

  16. Save the Great Lakes fisheries! (United States)

    Van Oosten, John


    During the winters of 1939-40 and 1940-41, two experiments involving 456 bobwhite quail, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to determine the palatability and comparative feeding value of 20 common wild quail-foods when offered as a part of a maintenance diet....2. Mortality was low on all diets, the highest occurring on that containing a mixture of bayberry and wax myrtle fruits. On all diets the birds showed increases in weight during the early winter. These gains were better maintained by birds on the wild foods than those on control diets composed entirely of cultivated feedstuffs.....3. There were statistically significant differences between the quantities of the various diets eaten.....4. For palatability and acceptability, seeds of common ragweed (Ambrosia artemisiifolia) and of shrub lespedeza (Lespedeza bicolor) were the preferred wild foods.....5. It is concluded that pen-reared bobwhite quail can be maintained successfully through winters in the vicinity of Washington, D. C., on diets containing 50 per cent of any one of the wild foods listed and 50 per cent of a high-caloric commercial seed mixture with yellow corn as the principal cereal.....6. The results of these 'cafeteria' studies, although interesting and indicative of the preferences of quail in confinement, do not necessarily represent selections that might be. made by bobwhites in the wild.

  17. Genetic population structure of muskellunge in the Great Lakes (United States)

    Kapuscinski, Kevin L.; Sloss, Brian L.; Farrell, John M.


    We quantified genetic relationships among Muskellunge Esox masquinongy from 15 locations in the Great Lakes to determine the extent and distribution of measurable population structure and to identify appropriate spatial scales for fishery management and genetic conservation. We hypothesized that Muskellunge from each area represented genetically distinct populations, which would be evident from analyses of genotype data. A total of 691 Muskellunge were sampled (n = 10–127/site) and genetic data were collected at 13 microsatellite loci. Results from a suite of analyses (including pairwise genetic differentiation, Bayesian admixture prediction, analysis of molecular variance, and tests of isolation by distance) indicated the presence of nine distinct genetic groups, including two that were approximately 50 km apart. Geographic proximity and low habitat complexity seemed to facilitate genetic similarity among areas, whereas Muskellunge from areas of greater habitat heterogeneity exhibited high differentiation. Muskellunge from most areas contained private alleles, and mean within-area genetic variation was similar to that reported for other freshwater fishes. Management programs aimed at conserving the broader diversity and long-term sustainability of Muskellunge could benefit by considering the genetically distinct groups as independent fisheries, and individual spawning and nursery habitats could subsequently be protected to conserve the evolutionary potential of Muskellunge.

  18. Potential Lacustrine Records of Cascadia Great Earthquakes (United States)

    Morey, A. E.; Goldfinger, C.; Briles, C.; Gavin, D. G.; Colombaroli, D.


    Lacustrine sediments have been used successfully over the past few decades to develop earthquake chronologies and rupture assessments in a variety of locations and settings, from large lakes in Japan and Chile to Alpine lakes in central Europe. Although inland lakes in the Pacific Northwest have been used extensively for fire and vegetation reconstructions, they have been largely ignored with respect to their tectonic setting. Strong shaking from great earthquakes at subduction zones is known to produce significant environmental disturbance and can result in lake deposits that are distinctive and datable records of these events. Cascadia paleoseismic studies, including those at Lake Washington, Bradley Lake, and Effingham and Saanich Inlets, provide direct evidence that records of Cascadia great earthquakes are preserved in a variety of sedimentary archives. The field of marine turbidite paleoseismology has resulted in advancements which we have now begun to apply to inland lacustrine sediments using the records at Sanger and Bolan Lakes (both spring-fed, alpine cirque lakes), and Upper Squaw Lake (a stream-fed, landslide-dammed lake) located 45-100 km inland from the coast near the California/Oregon border. Inorganic terrigenous layers are visible in these sediments, and physical property data (via CT scans, magnetic susceptibility and gamma density) show characteristics that correlate between lakes, and more surprisingly, correlate great distances to seismogenic offshore turbidite deposits. The highest resolution site is Upper Squaw Lake, a 7.2 ha landslide-dammed lake which drains a 40 km2 watershed. A 10 m core spanning the past 2,000 years was extracted from this site, and is comprised of silty gyttja interbedded with inorganic turbidite deposits. Six major events are observed this core, similar to the number of events in the marine turbidite record in the same time period, with supporting age control. The characteristics of the physical property data are

  20. Great Lakes Regional Biomass Energy Program

    International Nuclear Information System (INIS)

    Kuzel, F.


    The Great Lakes Regional Biomass Energy Program (GLRBEP) was initiated September, 1983, with a grant from the Office of Energy Efficiency and Renewable Energy of the US Department of Energy (DOE). The program provides resources to public and private organizations in the Great Lakes region to increase the utilization and production of biomass fuels. The objectives of the GLRBEP are to: (1) improve the capabilities and effectiveness of biomass energy programs in the state energy offices; (2) assess the availability of biomass resources for energy in light of other competing needs and uses; (3) encourage private sector investments in biomass energy technologies; (4) transfer the results of government-sponsored biomass research and development to the private sector; (5) eliminate or reduce barriers to private sector use of biomass fuels and technology; (6) prevent or substantially mitigate adverse environmental impacts of biomass energy use. The Program Director is responsible for the day-to-day activities of the GLRBEP and for implementing program mandates. A 40 member Technical Advisory Committee (TAC) sets priorities and recommends projects. The governor of each state in the region appoints a member to the Steering Council, which acts on recommendations of the TAC and sets basic program guidelines. The GLRBEP is divided into three separate operational elements. The State Grants component provides funds and direction to the seven state energy offices in the region to increase their capabilities in biomass energy. State-specific activities and interagency programs are emphasized. The Subcontractor component involves the issuance of solicitations to undertake projects that address regional needs, identified by the Technical Advisory Committee. The Technology Transfer component includes the development of nontechnical biomass energy publications and reports by Council staff and contractors, and the dissemination of information at conferences, workshops and other events

    China’s ascendance attracts concern, even though Beijing claims to be a responsible great power and tries to demonstrate its ‘great power style’ in economic diplomacy. This article therefore discusses the following questions: to what extent does the current notion and practice of Chinese ‘great...... power style’ in economic diplomacy comply with, or differ from, the criteria of benign hegemony; and what are the major constraining factors? Conceptually, China’s ‘great power style’ is rooted in ancient Chinese political philosophy and institution, but it highly resembles the Western notion of benign...... and economic interests....

  4. Incidental oligotrophication of North American Great Lakes. (United States)

    Evans, Mary Anne; Fahnenstiel, Gary; Scavia, Donald


    Phytoplankton production is an important factor in determining both ecosystem stability and the provision of ecosystem goods and services. The expansive and economically important North American Great Lakes are subjected to multiple stressors and understanding their responses to those stresses is important for understanding system-wide ecological controls. Here we show gradual increases in spring silica concentration (an indicator of decreasing growth of the dominant diatoms) in all basins of Lakes Michigan and Huron (USA and Canadian waters) between 1983 and 2008. These changes indicate the lakes have undergone gradual oligotrophication coincident with and anticipated by nutrient management implementation. Slow declines in seasonal drawdown of silica (proxy for seasonal phytoplankton production) also occurred, until recent years, when lake-wide responses were punctuated by abrupt decreases, putting them in the range of oligotrophic Lake Superior. The timing of these dramatic production drops is coincident with expansion of populations of invasive dreissenid mussels, particularly quagga mussels, in each basin. The combined effect of nutrient mitigation and invasive species expansion demonstrates the challenges facing large-scale ecosystems and suggest the need for new management regimes for large ecosystems.

  5. Annual crop type classification of the U.S. Great Plains for 2000 to 2011 (United States)

    Howard, Daniel M.; Wylie, Bruce K.


    The purpose of this study was to increase the spatial and temporal availability of crop classification data. In this study, nearly 16.2 million crop observation points were used in the training of the US Great Plains classification tree crop type model (CTM). Each observation point was further defined by weekly Normalized Difference Vegetation Index, annual climate, and a number of other biogeophysical environmental characteristics. This study accounted for the most prevalent crop types in the region, including, corn, soybeans, winter wheat, spring wheat, cotton, sorghum, and alfalfa. Annual CTM crop maps of the US Great Plains were created for 2000 to 2011 at a spatial resolution of 250 meters. The CTM achieved an 87 percent classification success rate on 1.8 million observation points that were withheld from model training. Product validation was performed on greater than 15,000 county records with a coefficient of determination of R2 = 0.76.

    The Great American Eclipse is over. Somewhat sad, is it not? Individuals who were unable to experience the event on August 21, 2017, can now cyber-observe the eclipse with Stellarium ( In the authors' opinion, it is fun and has many great applications in the classroom. In addition it is open source and available for Android, iOS, and Linux users. We here at Appalachian use it in our introductory astronomy labs for specific activities such as investigating coordinate systems, discovering differences between solar and sidereal days, as well as determining why your "astrological sign" is most often not your "astronomical sign."

These results will be related to comparative toxicity of other Great Lakes environmental compounds and to their application in site specific risk assessment.

  8. Great Plains Wind Energy Transmission Development Project

    Energy Technology Data Exchange (ETDEWEB)

    Brad G. Stevens, P.E.; Troy K. Simonsen; Kerryanne M. Leroux


    In fiscal year 2005, the Energy & Environmental Research Center (EERC) received funding from the U.S. Department of Energy (DOE) to undertake a broad array of tasks to either directly or indirectly address the barriers that faced much of the Great Plains states and their efforts to produce and transmit wind energy at the time. This program, entitled Great Plains Wind Energy Transmission Development Project, was focused on the central goal of stimulating wind energy development through expansion of new transmission capacity or development of new wind energy capacity through alternative market development. The original task structure was as follows: Task 1 - Regional Renewable Credit Tracking System (later rescoped to Small Wind Turbine Training Center); Task 2 - Multistate Transmission Collaborative; Task 3 - Wind Energy Forecasting System; and Task 4 - Analysis of the Long-Term Role of Hydrogen in the Region. As carried out, Task 1 involved the creation of the Small Wind Turbine Training Center (SWTTC). The SWTTC, located Grand Forks, North Dakota, consists of a single wind turbine, the Endurance S-250, on a 105-foot tilt-up guyed tower. The S-250 is connected to the electrical grid on the 'load side' of the electric meter, and the power produced by the wind turbine is consumed locally on the property. Establishment of the SWTTC will allow EERC personnel to provide educational opportunities to a wide range of participants, including grade school through college-level students and the general public. In addition, the facility will allow the EERC to provide technical training workshops related to the installation, operation, and maintenance of small wind turbines. In addition, under Task 1, the EERC hosted two small wind turbine workshops on May 18, 2010, and March 8, 2011, at the EERC in Grand Forks, North Dakota. Task 2 involved the EERC cosponsoring and aiding in the planning of three transmission workshops in the midwest and western regions. Under Task

  12. Great Salt Lake basins study unit (United States)

    Waddell, Kidd M.; Baskin, Robert L.


    In 1991, the U.S. Geological Survey (USGS) began implementing a full-scale National Water-Quality Assessment (NAWQA) Program.The long-term goals of the NAWQA Program are to describe the status and trends in the quality of a large, representative part of the Nation’s surface- and ground-water resources and to provide a sound, scientific understanding of the primary natural and human factors that affect the quality of these resources. In meeting these goals, the program will produce a wealth of water-quality information that will be useful to policy makers and managers at Federal, State, and local levels.A major design feature of the NAWQA Program will enable water-quality information at different areal scales to be integrated. A major component of the program is study-unit investigations, which ae the principal building blocks of the program upon which national-level assessment activities will be based. The 60 study-unit investigations that make up the program are hydrologic systems that include principal river basins and aquifer systems throughout the Nation. These study units cover areas from less than 1.000 to greater than 60,000 mi2 and incorporate from about 60 to 70 percent of the Nation’s water use and population served by public water supply. In 1993, assessment activities began in the Great Salt Lake Basins NAWQA study unit.

  13. Natural Selection in the Great Apes. (United States)

    Natural selection is crucial for the adaptation of populations to their environments. Here, we present the first global study of natural selection in the Hominidae (humans and great apes) based on genome-wide information from population samples representing all extant species (including most subspecies). Combining several neutrality tests we create a multi-species map of signatures of natural selection covering all major types of natural selection. We find that the estimated efficiency of both purifying and positive selection varies between species and is significantly correlated with their long-term effective population size. Thus, even the modest differences in population size among the closely related Hominidae lineages have resulted in differences in their ability to remove deleterious alleles and to adapt to changing environments. Most signatures of balancing and positive selection are species-specific, with signatures of balancing selection more often being shared among species. We also identify loci with evidence of positive selection across several lineages. Notably, we detect signatures of positive selection in several genes related to brain function, anatomy, diet and immune processes. Our results contribute to a better understanding of human evolution by putting the evidence of natural selection in humans within its larger evolutionary context. The global map of natural selection in our closest living relatives is available as an interactive browser at © The Author 2016.

  19. Economic feasibility of sail power devices on Great Lakes bulk carriers

    Energy Technology Data Exchange (ETDEWEB)


    Progress is reported in a project to determine whether retro-fitting existing Great Lakes bulk carriers with auxiliary sail powering devices is economically feasible. The approach being used is to apply known technology both in terms of sail devices and calculation methods to determine the amount of fuel that can be saved and the probable cost of the sail device. Progress includes the identification and collection of data needed to determine the state of the art as well as to model the problem. Several sail powering devices were compared and an unstayed cat rig was chosen for further analysis and its performance characteristics were incorporated into a computer model, which is flow charted.

  20. Hand preferences for coordinated bimanual actions in 777 great apes

    DEFF Research Database (Denmark)

    Hopkins, William D; Phillips, Kimberley A; Bania, Amanda


    Whether or not nonhuman primates exhibit population-level handedness remains a topic of considerable scientific debate. Here, we examined handedness for coordinated bimanual actions in a sample of 777 great apes including chimpanzees, bonobos, gorillas, and orangutans. We found population......-level right-handedness in chimpanzees, bonobos and gorillas, but left-handedness in orangutans. Directional biases in handedness were consistent across independent samples of apes within each genus. We suggest that, contrary to previous claims, population-level handedness is evident in great apes but differs...

  2. Cyclopoid and harpacticoid copepods of the Laurentian Great Lakes (United States)

    Hudson, Patrick L.; Reid, Janet W.; Lesko, Lynn T.; Selgeby, James H.


    Historical collections of cyclopoid and harpacticoid copepod crustaceans in the Great Lakes have mainly been based on samples taken with plankton nets in deeper waters (>5 m). Of the non-calanoid copepod species known from the Great Lakes, 58 or 64 live primarily on or in the sediments and rarely are collected in plankton samples. Because of their small size, they are rarely retained in the coarse sieves used to concentrate samples of benthic invertebrates. Thus, the abundance and distribution of most species of these two groups of copepods have never been adequately documented in the Great Lakes. We examined the stomach contents of small, bottom-feeding fishes such as slimy sculpin which feed on benthic copepods that live in deep, inaccessible rocky areas of the Great Lakes to collect some of the material. We also collected in shallow nearshore habitats, including wetlands. We present an annotated checklist of cyclopoid and harpacticoid copepods based on published records and our recent collections in the Great Lakes. We have added 14 species of cyclopoid copepods to the Great Lakes record, increasing the total to 30. Because we probably have accounted for most of the cyclopoid species, we provide a key to the identification of this group. We have added 19 species of harpacticoid copepods to the 15 previously known to the Great Lakes, and suspect that additional species remain to be discovered. In individual lakes, there were approximately as many species of cyclopoids as harpacticoids; the total number of species per lake ranged from 35 to 57. The most speciose genera were Bryocamptus (7), Canthocamptus (5), and Moraria (5) in the Harpacticoida, and Diacyclops (6) and Acanthocyclops (5) in the Cyclopoida. The origin of introduced species, our ability to classify copepod habitat, and the ecological significance of copepods are discussed.

    The GRavitational lEnsing Accuracy Testing 3 (GREAT3) challenge is the third in a series of image analysis challenges, with a goal of testing and facilitating the development of methods for analyzing astronomical images that will be used to measure weak gravitational lensing. This measurement requires extremely precise estimation of very small galaxy shape distortions, in the presence of far larger intrinsic galaxy shapes and distortions due to the blurring kernel caused by the atmosphere, telescope optics, and instrumental effects. The GREAT3 challenge is posed to the astronomy, machine learning, and statistics communities, and includes tests of three specific effects that are of immediate relevance to upcoming weak lensing surveys, two of which have never been tested in a community challenge before. These effects include many novel aspects including realistically complex galaxy models based on high-resolution imaging from space; a spatially varying, physically motivated blurring kernel; and a combination of multiple different exposures. To facilitate entry by people new to the field, and for use as a diagnostic tool, the simulation software for the challenge is publicly available, though the exact parameters used for the challenge are blinded. Sample scripts to analyze the challenge data using existing methods will also be provided. See and for more information

  10. Reaching Regional and Local Learners via a Great Lakes MOOC (United States)

    Mooney, M. E.; Ackerman, S. A.


    The Cooperative Institute of Meteorological Satellite Studies (CIMSS) took a regional approach to climate change education in a 4-week MOOC (Massive Open On-line Course) on the Changing Weather and Climate in the Great Lakes Region launched in February 2015. Featuring a different season each week, this Great Lakes MOOC includes lectures about seasonal weather conditions, observed changes, and societal impacts of regional climate change, as well as actions with co-benefits to slow future climate change. To better connect with learners, CIMSS facilitated 21 discussion groups at public libraries around Wisconsin each week. Participants discussed climate change impacts in their communities as well as strategies to mitigate climate change. Not surprisingly, initial survey results show library participants were more committed, engaged, climate literate, and community minded. This session will share lessons learned and survey results from the Great Lakes MOOC which remains open and accessible on Coursera through February 2016 at

  16. The Great Recession and risk for child abuse and neglect (United States)

    Schneider, William; Waldfogel, Jane; Brooks-Gunn, Jeanne


    This paper examines the association between the Great Recession and four measures of the risk for maternal child abuse and neglect: (1) maternal physical aggression; (2) maternal psychological aggression; (3) physical neglect by mothers; and (4) supervisory/exposure neglect by mothers. It draws on rich longitudinal data from the Fragile Families and Child Wellbeing Study, a longitudinal birth cohort study of families in 20 U.S. cities (N = 3,177; 50% African American, 25% Hispanic; 22% non-Hispanic white; 3% other). The study collected information for the 9-year follow-up survey before, during, and after the Great Recession (2007-2010). Interview dates were linked to two macroeconomic measures of the Great Recession: the national Consumer Sentiment Index and the local unemployment rate. Also included are a wide range of socio-demographic controls, as well as city fixed effects and controls for prior parenting. Results indicate that the Great Recession was associated with increased risk of child abuse but decreased risk of child neglect. Households with social fathers present may have been particularly adversely affected. Results also indicate that economic uncertainty during the Great Recession, as measured by the Consumer Sentiment Index and the unemployment rate, had direct effects on the risk of abuse or neglect, which were not mediated by individual-level measures of economic hardship or poor mental health.

  18. Malignant lymphomas (including myeloproliferative disorders)

    International Nuclear Information System (INIS)

    Todd, I.D.H.


    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

  20. Potential nitrogen critical loads for northern Great Plains grassland vegetation (United States)

    Symstad, Amy J.; Smith, Anine T.; Newton, Wesley E.; Knapp, Alan K.


    The National Park Service is concerned that increasing atmospheric nitrogen deposition caused by fossil fuel combustion and agricultural activities could adversely affect the northern Great Plains (NGP) ecosystems in its trust. The critical load concept facilitates communication between scientists and policy makers or land managers by translating the complex effects of air pollution on ecosystems into concrete numbers that can be used to inform air quality targets. A critical load is the exposure level below which significant harmful effects on sensitive elements of the environment do not occur. A recent review of the literature suggested that the nitrogen critical load for Great Plains vegetation is 10-25 kg N/ha/yr. For comparison, current atmospheric nitrogen deposition in NGP National Park Service (NPS) units ranges from ~4 kg N/ha/yr in the west to ~13 kg N/ha/yr in the east. The suggested critical load, however, was derived from studies far outside of the NGP, and from experiments investigating nitrogen loads substantially higher than current atmospheric deposition in the region.Therefore, to better determine the nitrogen critical load for sensitive elements in NGP parks, we conducted a four-year field experiment in three northern Great Plains vegetation types at Badlands and Wind Cave National Parks. The vegetation types were chosen because of their importance in NGP parks, their expected sensitivity to nitrogen addition, and to span a range of natural fertility. In the experiment, we added nitrogen at rates ranging from below current atmospheric deposition (2.5 kg N/ha/yr) to far above those levels but commensurate with earlier experiments (100 kg N/ha/yr). We measured the response of a variety of vegetation and soil characteristics shown to be sensitive to nitrogen addition in other studies, including plant biomass production, plant tissue nitrogen concentration, plant species richness and composition, non-native species abundance, and soil inorganic

  1. Wages, Productivity and Work Intensity in the Great Depression


    Julia Darby; Robert A Hart


    We show that U.S. manufacturing wages during the Great Depression were importantly determined by forces on firms' intensive margins. Short-run changes in work intensity and the longer-term goal of restoring full potential productivity combined to influence real wage growth. By contrast, the external effects of unemployment and replacement rates had much less impact. Empirical work is undertaken against the background of an efficient bargaining model that embraces employment, hours of work and...

  2. Climate change and the Great Barrier Reef

    International Nuclear Information System (INIS)

    Johnson, Johanna; Marshall, Paul


    Full text: Full text: Climate change is now recognised as the greatest long-term threat to the Great Barrier Reef (GBR). Managers face a future in which the impacts of climate change on tropical marine ecosystems are becoming increasingly frequent and severe. Further degradation is inevitable as the climate continues to change but the extent of the decline will depend on the rate and magnitude of climate change and the resilience of the ecosystem. Changes to the ecosystem have implications for the industries and regional communities that depend on the GBR. Climate projections for the GBR region include increasing air and sea temperatures, ocean acidification, nutrient enrichment (via changes in rainfall), altered light levels, more extreme weather events, changes to ocean circulation and sea level rise. Impacts have already been observed, with severe coral bleaching events in 1998 and 2002, and mass mortalities of seabirds linked to anomalously warm summer conditions. Climate change also poses significant threats to the industries and communities that depend on the GBR ecosystem, both directly and indirectly through loss of natural resources; industries such as recreational and commercial fishing, and tourism, which contributes to a regional tourism industry worth $6.1 billion (Access Economics 2005). A vulnerability assessment undertaken by leading experts in climate and marine science identified climate sensitivities for GBR species, habitats, key processes, GBR industries and communities (Johnson and Marshall 2007). This information has been used to develop a Climate Change Action Plan for the GBR. The Action Plan is a five-year program aimed at facilitating targeted science, building a resilient ecosystem, assisting adaptation of industries and communities, and reducing climate footprints. The Action Plan identifies strategies to review current management arrangements and raise awareness of the issue in order to work towards a resilient ecosystem. Integral to

  3. BOSS Great Wall: morphology, luminosity, and mass (United States)

    Context. Galaxy superclusters are the largest systems in the Universe that can give us information about the formation and evolution of the cosmic web. Aims: We study the morphology of the superclusters from the BOSS Great Wall (BGW), a recently discovered very rich supercluster complex at the redshift z = 0.47. Methods: We have employed the Minkowski functionals to quantify supercluster morphology. We calculate supercluster luminosities and masses using two methods. Firstly, we used data about the luminosities and stellar masses of high stellar mass galaxies with log (M∗/h-1M⊙) ≥ 11.3. Secondly, we applied a scaling relation that combines morphological and physical parameters of superclusters to obtain supercluster luminosities, and obtained supercluster masses using the mass-to-light ratios found for local rich superclusters. Results: The BGW superclusters are very elongated systems, with shape parameter values of less than 0.2. This value is lower than that found for the most elongated local superclusters. The values of the fourth Minkowski functional V3 for the richer BGW superclusters (V3 = 7 and 10) show that they have a complicated and rich inner structure. We identify two Planck SZ clusters in the BGW superclusters, one in the richest BGW supercluster, and another in one of the poor BGW superclusters. The luminosities of the BGW superclusters are in the range of 1-8 × 1013h-2L⊙, and masses in the range of 0.4-2.1 × 1016h-1M⊙. Supercluster luminosities and masses obtained with two methods agree well. Conclusions: The BGW is a complex of massive, luminous and large superclusters with very elongated shape. The search and detailed study, including the morphology analysis of the richest superclusters and their complexes from observations and simulations can help us to understand formation and evolution of the cosmic web.

  4. Energy and water in the Great Lakes.

    Energy Technology Data Exchange (ETDEWEB)

    Tidwell, Vincent Carroll


    The nexus between thermoelectric power production and water use is not uniform across the U.S., but rather differs according to regional physiography, demography, power plant fleet composition, and the transmission network. That is, in some regions water demand for thermoelectric production is relatively small while in other regions it represents the dominate use. The later is the case for the Great Lakes region, which has important implications for the water resources and aquatic ecology of the Great Lakes watershed. This is today, but what about the future? Projected demographic trends, shifting lifestyles, and economic growth coupled with the threat of global climate change and mounting pressure for greater U.S. energy security could have profound effects on the region's energy future. Planning for such an uncertain future is further complicated by the fact that energy and environmental planning and regulatory decisionmaking is largely bifurcated in the region, with environmental and water resource concerns generally taken into account after new energy facilities and technologies have been proposed, or practices are already in place. Based on these confounding needs, the objective of this effort is to develop Great Lakes-specific methods and tools to integrate energy and water resource planning and thereby support the dual goals of smarter energy planning and development, and protection of Great Lakes water resources. Guiding policies for this planning are the Great Lakes and St. Lawrence River Basin Water Resources Compact and the Great Lakes Water Quality Agreement. The desired outcome of integrated energy-water-aquatic resource planning is a more sustainable regional energy mix for the Great Lakes basin ecosystem.

  5. The Great East Japan Earthquake Disaster and cardiovascular diseases. (United States)

    Aoki, Tatsuo; Fukumoto, Yoshihiro; Yasuda, Satoshi; Sakata, Yasuhiko; Ito, Kenta; Takahashi, Jun; Miyata, Satoshi; Tsuji, Ichiro; Shimokawa, Hiroaki


    While previous studies reported a short-term increase in individual cardiovascular disease (CVD) after great earthquakes, mid-term occurrences of all types of CVDs after great earthquakes are unknown. We addressed this important issue in our experience with the Great East Japan Earthquake (11 March 2011). We retrospectively examined the impact of the Earthquake on the occurrences of CVDs and pneumonia by comparing the ambulance records made by doctors in our Miyagi Prefecture, the centre of the disaster area, during the periods of 2008-11 (n = 124,152). The weekly occurrences of CVDs, including heart failure (HF), acute coronary syndrome (ACS), stroke, cardiopulmonary arrest (CPA), and pneumonia were all significantly increased after the Earthquake compared with the previous 3 years. The occurrences of ACS and CPA showed the rapid increase followed by a sharp decline, whereas those of HF and pneumonia showed a prolonged increase for more than 6 weeks and those of stroke and CPA showed a second peak after the largest aftershock (7 April 2011). Furthermore, the occurrence of CPA was increased in the first 24 h after the Earthquake, followed by other diseases later on. These increases were independent of age, sex, or residence area (seacoast vs. inland). These results indicate that the occurrences of all types of CVDs and pneumonia were increased in somewhat different time courses after the Earthquake, including the first observation of the marked and prolonged increase in HF, emphasizing the importance of intensive medical management of all types of CVDs after great earthquakes.

  6. Aerosol simulation including chemical and nuclear reactions

    International Nuclear Information System (INIS)

    Marwil, E.S.; Lemmon, E.C.


    The numerical simulation of aerosol transport, including the effects of chemical and nuclear reactions presents a challenging dynamic accounting problem. Particles of different sizes agglomerate and settle out due to various mechanisms, such as diffusion, diffusiophoresis, thermophoresis, gravitational settling, turbulent acceleration, and centrifugal acceleration. Particles also change size, due to the condensation and evaporation of materials on the particle. Heterogeneous chemical reactions occur at the interface between a particle and the suspending medium, or a surface and the gas in the aerosol. Homogeneous chemical reactions occur within the aersol suspending medium, within a particle, and on a surface. These reactions may include a phase change. Nuclear reactions occur in all locations. These spontaneous transmutations from one element form to another occur at greatly varying rates and may result in phase or chemical changes which complicate the accounting process. This paper presents an approach for inclusion of these effects on the transport of aerosols. The accounting system is very complex and results in a large set of stiff ordinary differential equations (ODEs). The techniques for numerical solution of these ODEs require special attention to achieve their solution in an efficient and affordable manner. 4 refs

  7. A psychoanalytic study of Alexander the Great. (United States)

    Thomas, K R


    The purpose of this paper was to demonstrate how Freudian concepts such as the Oedipus complex, castration anxiety, fear of loss of love, the psychosexual stages of development, and the tripartite structure of personality can be used to understand the life and achievements of Alexander the Great. To accomplish this purpose, specific incidents, myths, and relationships in Alexander's life were analyzed from a Freudian psychoanalytic perspective. Green (1991), in his recent biography of Alexander, has questioned the merit of using Freudian concepts to understand Alexander's character. In fact, he stated specifically: If he (Alexander) had any kind of Oedipus complex it came in a poor second to the burning dynastic ambition which Olympias so sedulously fostered in him; those who insist on his psychological motivation would do better to take Adler as their mentor than Freud (p.56). Later, in the concluding section of his book, Green (1991, pp. 486-487) discounted Freudian interpretations of Alexander's distaste for sex, the rumors of his homosexual liaisons, his partiality for middle-aged or elderly ladies, and the systematic domination of his early years by Olympias as little more than the projected fears and desires of the interpreters. And again, an Adlerian power-complex paradigm was suggested as the preferable theoretical framework to use. Green's argument was based primarily on an exchange, reported originally by Plutarch, which took place between Alexander and Philip prior to Alexander's tutorship with Aristotle. Purportedly, Philip enjoined his son to study hard and pay close attention to all Aristotle said "so that you may not do a great many things of the sort that I am sorry I have done." At this point, Alexander "somewhat pertly" took Philip to task "because he was having children by other women besides his wife." Philip's reply was: "Well then, if you have many competitors for the kingdom, prove yourself honorable and good, so that you may obtain the

  8. Using Scenario Development to Encourage Tourism Business Resilience in the Great Lakes (United States)

    Chin, N.; Day, J.; Sydnor, S.; Cherkauer, K. A.


    Tourism is an economic sector anticipated to be greatly affected by climate change, but the potential impacts of climate change on tourism have rarely been examined in detail in existing research. Past research has shown, however, that the small and medium businesses that dominate the tourism sector could be greatly impacted by climate change. We have presented global climate and hydrologic model research results to pre-selected coastal tourism business owners in the Great Lakes region to determine the best methods for delivering user-friendly future climate scenarios, given that existing research suggests that climate change adaptive behaviors and resilience increase with information (message) clarity. Model output analyses completed for this work have focused on temperature, precipitation, and extreme weather events due to their economic impact on tourism activities. We have also experimented with the development and use of infographics because of their ability to present information quickly and clearly. Initial findings of this work will be presented as well as lessons learned from stakeholder interactions. Two main results include that (1) extreme weather events may have more meaning to tourism business owners than general trends in climate and (2) long-term planning for climate is extremely difficult for tourism business owners because they operate on a much shorter planning timeline than those generally used for climate change analyses.

  9. ["Great jobs"-also in psychiatry?]. (United States)

    Spiessl, H; Hübner-Liebermann, B


    Against the background of a beginning shortage of psychiatrists, results from interviews with 112 employees of an automotive company with the topic "Great Job" are presented to discuss their relevance to psychiatry. The interviews were analysed by means of a qualitative content analysis. Most employees assigned importance to great pay, constructive collaboration with colleagues, and work appealing to personal interests. Further statements particularly relevant to psychiatry were: successful career, flexible working hours, manageable job, work-life balance, well-founded training, no bureaucracy within the company, and personal status in society. The well-known economic restrictions in health care and the still negative attitude towards psychiatry currently reduce the attraction of psychiatry as a profession. From the viewpoint of personnel management, the attractors of a great job revealed in this study are proposed as important clues for the recruitment of medical students for psychiatry and the development of psychiatric staff.

  10. Labor Unions and the Great Recession

    Directory of Open Access Journals (Sweden)

    Ruth Milkman


    Full Text Available This article examines the impact of the Great Recession on the U.S. labor movement. After reviewing the classic industrial relations literature on the relationship between unionization rates and business cycles, we analyze historical union density trends. After documenting the relentless downward trend in the private sector from the early 1980s, with no apparent relationship to the business cycle, we analyze the negative impact of the political dynamic that unfolded in the wake of the Great Recession on public-sector unionism in sharp contrast to what took place during the Great Depression. We also explore the new forms of labor organizing that have emerged in the private sector, which have capitalized on the growing public concern about rising inequality sparked by Occupy Wall Street.

  11. Great Lakes Integrated Sciences + Assessments: Connecting Users and Generators of Scientific Information to Inform Climate Change Adaptation (United States)

    Baule, W. J.; Briley, L.; Brown, D.; Gibbons, E.


    The Great Lakes Integrated Sciences + Assessments (GLISA) is one of eleven NOAA Regional Integrated Sciences and Assessments (RISAs) and is a co-hosted by the University of Michigan and Michigan State University. The Great Lakes region falls between areas that are typically defined as the Midwest and Northeast in the United States and also includes portions of Ontario in Canada. This unique and complex region holds approximately 21% of global surface fresh water and is home to 23 million people on the United States side of the basin alone. GLISA functions as a bridge between climate science researchers and boundary organizations in the Great Lakes region, with the goals of contributing to the long-term sustainability of the region in face of a changing climate and to facilitate smart decision-making backed by sound scientific knowledge. Faculty and staff associated with GLISA implement physical and social science practices in daily operations, which includes but is not limited to: activating the boundary chain model to facilitate the transfer of knowledge through the community, integrating local and historical climate data into decision-making processes, addressing uncertainty and the downscaling of climate information, and implementing network analyses to find key access points to information networks across the Great Lakes region. GLISA also provides funding for projects related to climate and climate change adaptation in the Great Lakes region, as well as expertise to partner organizations through collaborations. Information from boundary organizations, stakeholders, and collaborators also flows back to GLISA to aid in the determination of the physical and social science needs of the region. Recent findings point to GLISA playing a crucial role in the scaling information across scales of government and ensuring that federal agencies and local stakeholders are able to learn from one another and share experiences and knowledge to continue building climate ready

  12. Great Basin geologic framework and uranium favorability

    International Nuclear Information System (INIS)

    Larson, L.T.; Beal, L.H.


    Work on this report has been done by a team of seven investigators assisted over the project span by twenty-three undergraduate and graduate students from May 18, 1976 to August 19, 1977. The report is presented in one volume of text, one volume or Folio of Maps, and two volumes of bibliography. The bibliography contains approximately 5300 references on geologic subjects pertinent to the search for uranium in the Great Basin. Volume I of the bibliography lists articles by author alphabetically and Volume II cross-indexes these articles by location and key word. Chapters I through IV of the Text volume and accompanying Folio Map Sets 1, 2, 3, 4, and 5, discuss the relationship of uranium to rock and structural environments which dominate the Great Basin. Chapter 5 and Map Sets 6 and 7 provide a geochemical association/metallogenic grouping of mineral occurrences in the Great Basin along with information on rock types hosting uranium. Chapter VI summarizes the results of a court house claim record search for 'new' claiming areas for uranium, and Chapter VII along with Folio Map Set 8 gives all published geochronological data available through April 1, 1977 on rocks of the Great Basin. Chapter VIII provides an introduction to a computer analysis of characteristics of certain major uranium deposits in crystalline rocks (worldwide) and is offered as a suggestion of what might be done with uranium in all geologic environments. We believe such analysis will assist materially in constructing exploration models. Chapter IX summarizes criteria used and conclusions reached as to the favorability of uranium environments which we believe to exist in the Great Basin and concludes with recommendations for both exploration and future research. A general summary conclusion is that there are several geologic environments within the Great Basin which have considerable potential and that few, if any, have been sufficiently tested

  14. Southern Great Plains Rapid Ecoregional Assessment: pre-assessment report (United States)

    Assal, Timothy J.; Melcher, Cynthia P.; Carr, Natasha B.


    The purpose of the Pre-Assessment Report for the Southern Great Plains Rapid Ecoregional Assessment (REA) is to document the selection process for and final list of Conservation Elements, Change Agents, and Management Questions developed during Phase I. The overall goal of the REAs being conducted for the Bureau of Land Management (BLM) is to provide information that supports regional planning and analysis for the management of ecological resources. The REA provides an assessment of baseline ecological conditions, an evaluation of current risks from drivers of ecosystem change, and a predictive capacity for evaluating future risks. The REA also may be used for identifying priority areas for conservation or restoration and for assessing the cumulative effects of a variety of land uses. There are several components of the REAs. Management Questions, developed by the BLM and partners for the ecoregion, identify the information needed for addressing land-management responsibilities. Conservation Elements represent regionally significant terrestrial and aquatic species and communities that are to be conserved and (or) restored. For each Conservation Element, key ecological attributes will be evaluated to determine the status of each species and community. The REA also will evaluate major drivers of ecosystem change, or Change Agents, currently affecting or likely to affect the status of Conservation Elements in the future. The relationships between Change Agents and key ecological attributes will be summarized using conceptual models. The REA process is a two-phase process. Phase I (pre-assessment) includes developing and finalizing the lists of priority Management Questions, Conservation Elements, and Change Agents, culminating in the REA Pre-Assessment Report.

  18. Ernst Chain: a great man of science. (United States)

    Kardos, Nelson; Demain, Arnold L


    resources were scarce in postwar Britain, the British government declined the project. Chain then took a post in 1948 at Rome's Instituto Superiore di Sanitá, establishing a new biochemistry department with a pilot plant. During that period, his department developed important new antibiotics (including the first semisynthetic antibiotics) as well as improved technological processes to produce a wide variety of important microbial metabolites that are still in wide use today. Chain was also responsible for helping several countries to start up a modern penicillin industry following World War II, including the Soviet Union and the People's Republic of China. In 1964, Chain returned to England to establish a new biochemistry department and industrial scale fermentation pilot plant at Imperial College in London. Imperial College became the preeminent biochemical department in Europe. Chain was also a pioneer in changing the relationship between government, private universities, and private industry for collaboration and funding to support medical research. Ernst Chain has left a lasting impact as a great scientist and internationalist.

  8. The Younger Dryas phase of Great Salt Lake, Utah, USA (United States)

    Oviatt, Charles G.; Miller, D.M.; McGeehin, J.P.; Zachary, C.; Mahan, S.


    Field investigations at the Public Shooting Grounds (a wildlife-management area on the northeastern shore of Great Salt Lake) and radiocarbon dating show that the Great Salt Lake rose to the Gilbert shoreline sometime between 12.9 and 11.2 cal ka. We interpret a ripple-laminated sand unit exposed at the Public Shooting Grounds, and dated to this time interval, as the nearshore sediments of Great Salt Lake deposited during the formation of the Gilbert shoreline. The ripple-laminated sand is overlain by channel-fill deposits that overlap in age (11.9-11.2 cal ka) with the sand, and by wetland deposits (11.1 to 10.5 cal ka). Consistent accelerator mass spectrometry radiocarbon ages were obtained from samples of plant fragments, including those of emergent aquatic plants, but mollusk shells from spring and marsh deposits yielded anomalously old ages, probably because of a variable radiocarbon reservoir effect. The Bonneville basin was effectively wet during at least part of the Younger Dryas global-cooling interval, however, conflicting results from some Great Basin locations and proxy records indicate that the regional effects of Younger Dryas cooling are still not well understood. ?? 2005 Elsevier B.V.

    20 patients with the diagnosis of congenital corrected transposition of great arteries were analyzed. The diagnosis was based on routine clinical examination, echocardiography and in certain cases on heart catheterization and angiocardiography. In the most cases c-TGA coexists with additional heart defects. The commonest coexisting defects were: ventricular septal defect (60%), pulmonary stenosis (50%), atrio-ventricular valve regurgitation, predominantly systemic (tricuspid 45%). In the most cases 2D Doppler echo examination was sufficient for morphological assessment. In order to quality to cardiosurgical treatment heart catheterization and angiocardiography were necessary. 5 children were treated surgically. 3 of them underwent palliative procedures, one - Rastelli procedure and one had corrective surgery with bad result. Clinical picture of corrected transposition of great arteries is determined by coexisting additional heart defects. (author) 15 refs, 6 figs, 1 tab

  10. Functional Implications of Human-Specific Changes in Great Ape microRNAs.

    Directory of Open Access Journals (Sweden)

    Alicia Gallego

    Full Text Available microRNAs are crucial post-transcriptional regulators of gene expression involved in a wide range of biological processes. Although microRNAs are highly conserved among species, the functional implications of existing lineage-specific changes and their role in determining differences between humans and other great apes have not been specifically addressed. We analyzed the recent evolutionary history of 1,595 human microRNAs by looking at their intra- and inter-species variation in great apes using high-coverage sequenced genomes of 82 individuals including gorillas, orangutans, bonobos, chimpanzees and humans. We explored the strength of purifying selection among microRNA regions and found that the seed and mature regions are under similar and stronger constraint than the precursor region. We further constructed a comprehensive catalogue of microRNA species-specific nucleotide substitutions among great apes and, for the first time, investigated the biological relevance that human-specific changes in microRNAs may have had in great ape evolution. Expression and functional analyses of four microRNAs (miR-299-3p, miR-503-3p, miR-508-3p and miR-541-3p revealed that lineage-specific nucleotide substitutions and changes in the length of these microRNAs alter their expression as well as the repertoires of target genes and regulatory networks. We suggest that the studied molecular changes could have modified crucial microRNA functions shaping phenotypes that, ultimately, became human-specific. Our work provides a frame to study the impact that regulatory changes may have in the recent evolution of our species.

  13. The Cultural Heritage of the Great Prespa Region

    Directory of Open Access Journals (Sweden)

    Ema Muslli


    Full Text Available The Great Prespa region is situated in the Balkan Peninsula and is divided between Albania, Macedonia and Greece. It includes the Great Prespa Lake and the surrounding beach and meadow, areas designated for agricultural use and the towns of Pusteci (formerly known as Liqenas and Resen. This region is now part of the Trans-Boundary Biosphere Reserve ‘Ohrid-Prespa Watershed. Great and Small Prespa lakes plus Ohrid Lake are included in this newly-approved UNESCO world Heritage Site, but for this paper, we are looking only at the area surrounding the Great Prespa Lake. It is critical for this area to be protected immediately, because of the overuse it has undergone in recent years. While current levels of fauna are dangerously declining due to recent over-harvesting, this area has been known historically for its diverse natural and cultural features. Thus it is important to take drastic measures to reclaim the natural beauty immediately, including those areas currently covered by Prespa National Parks in Albania and Greece and Galichica and Pelisteri National Parks in Macedonia. Due to many wars over the centuries, it exists a mixture of Albanian and Macedonian culture. The historical and architectural remaining, religious structures and artifacts testify the richness and uniqueness of the communities of Pustec and Resen have. The cultural heritage is now a key element designated for the development of the region’s sustainable tourism development. This study was enhanced via the Geographic Info System (GIS digital presentation showing the opportunities for natural and cultural tourism in both countries (Albania and Macedonia.

  14. Turbulent Region Near Jupiter's Great Red Spot (United States)


    True and false color mosaics of the turbulent region west of Jupiter's Great Red Spot. The Great Red Spot is on the planetary limb on the right hand side of each mosaic. The region west (left) of the Great Red Spot is characterized by large, turbulent structures that rapidly change in appearance. The turbulence results from the collision of a westward jet that is deflected northward by the Great Red Spot into a higher latitude eastward jet. The large eddies nearest to the Great Red Spot are bright, suggesting that convection and cloud formation are active there.The top mosaic combines the violet (410 nanometers) and near infrared continuum (756 nanometers) filter images to create a mosaic similar to how Jupiter would appear to human eyes. Differences in coloration are due to the composition and abundance of trace chemicals in Jupiter's atmosphere. The lower mosaic uses the Galileo imaging camera's three near-infrared (invisible) wavelengths (756 nanometers, 727 nanometers, and 889 nanometers displayed in red, green, and blue) to show variations in cloud height and thickness. Light blue clouds are high and thin, reddish clouds are deep, and white clouds are high and thick. Purple most likely represents a high haze overlying a clear deep atmosphere. Galileo is the first spacecraft to distinguish cloud layers on Jupiter.The mosaic is centered at 16.5 degrees south planetocentric latitude and 85 degrees west longitude. The north-south dimension of the Great Red Spot is approximately 11,000 kilometers. The smallest resolved features are tens of kilometers in size. North is at the top of the picture. The images used were taken on June 26, 1997 at a range of 1.2 million kilometers (1.05 million miles) by the Solid State Imaging (SSI) system on NASA's Galileo spacecraft.The Jet Propulsion Laboratory, Pasadena, CA manages the Galileo mission for NASA's Office of Space Science, Washington, DC.

    Full Text Available The Great Silk Road (GSR called so in the late 19th century by German geographer Ferdinand von Richthofen started shaping in the 2nd century B.C. In the minds of peoples the Silk Road is a generalized symbol of trade caravan routes crossing Central Asia, connecting until the 16th century the Far East, in particular Japan, China, with Middle Asia. Appearance in the early 21st century of new independent states in Central Asia along the GSR route was a powerful impetus for revival of the ancient trade route. In September 2013 Xi Jinping, President of the People's Republic of China, during his visit to the Central Asian countries offered the strategic concept of joint construction of the “economic corridor along the Silk Road” based on innovative cooperation in order to revive and consolidate the economic contacts among the Eurasian countries. Establishment of the modern analog of GSR, a powerful transport and pipeline corridor includes the integrated system of railroads and automobile roads, oil and gas pipelines, airlines, and sea lines.

  16. Great red spot dependence on solar activity

    International Nuclear Information System (INIS)

    Schatten, K.H.


    A new inquiry has been made into the question of whether Jupiter's Great Red Spot shows a solar activity dependence. From 1892 to 1947 a clear correlation was present. A dearth of sightings in the seventeenth century, along with the Maunder Minimum, further supports the relation. An anticorrelation, however, from l948 to l967 removed support for such an effect. The old observations have reexamined and recent observations have also been studied. The author reexamines this difficult question and suggests a possible physical mechanism for a Sun-Jovian weather relation. Prinn and Lewis' conversion reaction of Phosphine gas to triclinic red phosphorous crystals is a reaction dependent upon solar radiation. It may explain the dependence found, as well as the striking appearance of the Great Red Spot in the UV

  18. Hospital Capital Investment During the Great Recession (United States)

    Choi, Sung


    Hospital capital investment is important for acquiring and maintaining technology and equipment needed to provide health care. Reduction in capital investment by a hospital has negative implications for patient outcomes. Most hospitals rely on debt and internal cash flow to fund capital investment. The great recession may have made it difficult for hospitals to borrow, thus reducing their capital investment. I investigated the impact of the great recession on capital investment made by California hospitals. Modeling how hospital capital investment may have been liquidity constrained during the recession is a novel contribution to the literature. I estimated the model with California Office of Statewide Health Planning and Development data and system generalized method of moments. Findings suggest that not-for-profit and public hospitals were liquidity constrained during the recession. Comparing the changes in hospital capital investment between 2006 and 2009 showed that hospitals used cash flow to increase capital investment by $2.45 million, other things equal. PMID:28617202

  20. Alexander the Great's relationship with alcohol. (United States)

    Liappas, J A; Lascaratos, J; Fafouti, S; Christodoulou, G N


    This study sought to clarify if Alexander the Great indulged pathologically in alcohol and whether it contributed to his death. The texts of the historians Diodorus of Sicily, Plutarch, Arrian, Curtius Rufus, Athenaeus, Aelian and Justin were studied, with their information concerning wine consumption by Macedonians, and especially Alexander, and were evaluated. The surviving historical texts, all later than Alexander's epoch, are based on a series of contemporary histories and especially on the 'Royal Journals', an official diary written in the imperial court. Alexander consumed large quantities of undiluted wine periodically, reaching pathological intoxication. However, the existing data do not provide convincing evidence that Alexander the Great manifested abuse of or dependence on alcohol according to DSM-IV or ICD-10 criteria and it seems unlikely that alcohol was involved in his untimely death.

  2. Population genetics of Great Basin feral horses. (United States)

    Bowling, A T


    The genetic make-up of Great Basin wild (feral) horses was investigated by blood typing studies. Blood samples of 975 feral horses from seven trap sites in Nevada and Oregon were tested by serological and electrophoretic techniques for genetic markers at 19 polymorphic loci. The average number of variants for the seven feral populations [72.1 +/- 3.2 (SEM), range 62-85] was not significantly different from that of 16 domestic breeds (75.0 +/- 11.5, range 58-105). The expected average frequency of heterozygotes per locus (average heterozygosity) for the feral populations (0.402 +/- 0.009, range 0.368-0.442) was not significantly different from the domestic breeds (0.389 +/- 0.045, range 0.295-0.443). Dendrograms constructed using pairwise comparisons of Nei's distance measurements substantiated anecdotal accounts of the origins of Great Basin horses from Iberian, American saddle horse and draft horse breeds.

  3. Gold Veins near Great Falls, Maryland (United States)

    Reed, John Calvin; Reed, John C.


    Small deposits of native gold are present along an anastomosing system of quartz veins and shear zones just east of Great Falls, Montgomery County, Md. The deposits were discovered in 1861 and were worked sporadically until 1951, yielding more than 5,000 ounces of gold. The vein system and the principal veins within it strike a few degrees west of north, at an appreciable angle to foliation and fold axial planes in enclosing rocks of the Wissahickon Formation of late Precambrian (?) age. The veins cut granitic rocks of Devonian or pre-Devonian age and may be as young as Triassic. Further development of the deposits is unlikely under present economic conditions because of their generally low gold content and because much of the vein system lies on park property, but study of the Great Falls vein system may be useful in the search for similar deposits elsewhere in the Appalachian Piedmont.

  8. Fire rehabilitation effectiveness: a chronosequence approach for the Great Basin (United States)

    Pyke, David A.; Pilliod, David S.; Chambers, Jeanne C.; Brooks, Matthew L.; Grace, James


    Federal land management agencies have invested heavily in seeding vegetation for emergency stabilization and rehabilitation (ES&R) of non-forested lands. ES&R projects are implemented to reduce post-fire dominance of non-native annual grasses, minimize probability of recurrent fire, quickly recover lost habitat for sensitive species, and ultimately result in plant communities with desirable characteristics including resistance to invasive species and resilience or ability to recover following disturbance. Land managers lack scientific evidence to verify whether seeding non-forested lands achieves their desired long-term ES&R objectives. The overall objective of our investigation is to determine if ES&R projects increase perennial plant cover, improve community composition, decrease invasive annual plant cover and result in a more desirable fuel structure relative to no treatment following fires while potentially providing habitat for Greater Sage-Grouse, a species of management concern. In addition, we provide the locations and baseline vegetation data for further studies relating to ES&R project impacts. We examined effects of seeding treatments (drill and broadcast) vs. no seeding on biotic and abiotic (bare ground and litter) variables for the dominant climate regimes and ecological types within the Great Basin. We attempted to determine seeding effectiveness to provide desired plant species cover while restricting non-native annual grass cover relative to post-treatment precipitation, post-treatment grazing level and time-since-seeding. Seedings were randomly sampled from all known post-fire seedings that occurred in the four-state area of Idaho, Nevada, Oregon and Utah. Sampling locations were stratified by major land resource area, precipitation, and loam-dominated soils to ensure an adequate spread of locations to provide inference of our findings to similar lands throughout the Great Basin. Nearly 100 sites were located that contained an ES&R project. Of

Neuropraxia of the great auricular nerve (GAN is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently. Keywords: neuropraxia, anesthesia, arthroscopy, great auricular nerve

  10. Catchment management and the Great Barrier Reef. (United States)

    Brodie, J; Christie, C; Devlin, M; Haynes, D; Morris, S; Ramsay, M; Waterhouse, J; Yorkston, H


    Pollution of coastal regions of the Great Barrier Reef is dominated by runoff from the adjacent catchment. Catchment land-use is dominated by beef grazing and cropping, largely sugarcane cultivation, with relatively minor urban development. Runoff of sediment, nutrients and pesticides is increasing and for nitrogen is now four times the natural amount discharged 150 years ago. Significant effects and potential threats are now evident on inshore reefs, seagrasses and marine animals. There is no effective legislation or processes in place to manage agricultural pollution. The Great Barrier Reef Marine Park Act does not provide effective jurisdiction on the catchment. Queensland legislation relies on voluntary codes and there is no assessment of the effectiveness of the codes. Integrated catchment management strategies, also voluntary, provide some positive outcomes but are of limited success. Pollutant loads are predicted to continue to increase and it is unlikely that current management regimes will prevent this. New mechanisms to prevent continued degradation of inshore ecosystems of the Great Barrier Reef World Heritage Area are urgently needed.

  11. Moral reasoning about great apes in research (United States)

    Okamoto, Carol Midori


    This study explored how individuals (biomedical scientists, Great Ape Project activists, lay adults, undergraduate biology and environmental studies students, and Grade 12 and 9 biology students) morally judge and reason about using great apes in biomedical and language research. How these groups perceived great apes' mental capacities (e.g., pain, logical thinking) and how these perceptions related to their judgments were investigated through two scenarios. In addition, the kinds of informational statements (e.g., biology, economics) that may affect individuals' scenario judgments were investigated. A negative correlation was found between mental attributions and scenario judgments while no clear pattern occurred for the informational statements. For the biomedical scenario, all groups significantly differed in mean judgment ratings except for the biomedical scientists, GAP activists and Grade 9 students. For the language scenario, all groups differed except for the GAP activists, and undergraduate environmental studies and Grade 9 students. An in-depth qualitative analysis showed that although the biomedical scientists, GAP activists and Grade 9 students had similar judgments, they produced different mean percentages of justifications under four moral frameworks (virtue, utilitarianism, deontology, and welfare). The GAP activists used more virtue reasoning while the biomedical scientists and Grade 9 students used more utilitarian and welfare reasoning, respectively. The results are discussed in terms of developing environmental/humane education curricula.

    The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consists of transposition of great arteries and ventricular inversion, and which is caused by abnormal development of conotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to get accurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between September 1976 and June 1981. The clinical, radiographic, and operative findings with the emphasis on the angiocardiographic findings were analyzed. The results are as follows: 1. Among 18 cases, 13 cases have normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia with situs inversus and 1 case has levocardia with situs inversus. 2. Segmental sets are (S, L, L) in 15 cases, and (I, D,D) in 3 cases and there is no exception to loop rule. 3. Side by side interrelationships of both ventricles and both semilunar valves are noticed in 10 and 12 cases respectively. 4. Subaortic type conus is noted in all 18 cases. 5. Associated cardic malformations are VSD in 14 cases, PS in 11, PDA in 3, PFO in 3, ASD in 2, right aortic arch in 2, tricuspid insufficiency, mitral prolapse, persistent left SVC and persistent right SVC in 1 case respectively. 6. For accurate diagnosis of corrected TGA, selective biventriculography using biplane cineradiography is an essential procedure

  13. Geothermal fluid genesis in the Great Basin

    Energy Technology Data Exchange (ETDEWEB)

    Flynn, T.; Buchanan, P.K.


    Early theories concerning geothermal recharge in the Great Basin implied recharge was by recent precipitation. Physical, chemical, and isotopic differences between thermal and non-thermal fluids and global paleoclimatic indicators suggest that recharge occurred during the late Pleistocene. Polar region isotopic studies demonstrate that a depletion in stable light-isotopes of precipitation existed during the late Pleistocene due to the colder, wetter climate. Isotopic analysis of calcite veins and packrat midden megafossils confirm the depletion event occurred in the Great Basin. Isotopic analysis of non-thermal springs is utilized as a proxy for local recent precipitation. Contoured plots of deuterium concentrations from non-thermal and thermal water show a regional, systematic variation. Subtracting contoured plots of non-thermal water from plots of thermal water reveals that thermal waters on a regional scale are generally isotopically more depleted. Isolated areas where thermal water is more enriched than non-thermal water correspond to locations of pluvial Lakes Lahontan and Bonneville, suggesting isotopically enriched lake water contributed to fluid recharge. These anomalous waters also contain high concentrations of sodium chloride, boron, and other dissolved species suggestive of evaporative enrichment. Carbon-age date and isotopic data from Great Basin thermal waters correlate with the polar paleoclimate studies. Recharge occurred along range bounding faults. 151 refs., 62 figs., 15 tabs.

    Full Text Available The Great Temple of Bel in Palmyra was a unique edifice which had blended the well established lines of Greco-Roman architecture with the art and taste of the Orient. With the gilded bronze capitals of its 41 Corinthian columns it was the product of enormous effort and budget. It was the gem of a remarkable epoch of wealthy Palmyra and mighty Roma. With its splendidly decorated adyta ceilings it became a source of inspiration and imagination for Western architecture and decorative arts. While continuing to captivate the World, it was leveled and vanished as a grim result of conflict based vandalism. The aim of this work is to piece together this, the most eloquent and stupendous monument of the Roman East, from its ruins and reconstruct it as it was once extant. Its loss is irreplacable, but its photo-realistic reconstruction can offer some solace by waking the memories of the great temple as in the past. The lost reality of the Great Temple of Bel is revived here by digitally constructing its “ghost images".

  15. THE ROLE OF FARMERS IN MANAGING WATER Dr Tony Colman Professor Tony Allan Farmers manage about 92% of the water consumed by society which needs to recognise that farming practices and the decisions made by those who operate food supply chains - including corporates and those making public policy - determine how water is stewarded. (United States)

    Colman, A. J.


    Title Food-water and society Dr. Tony Colman and Professor Tony Allan Abstract The purpose of the paper is to highlight some key relationships between water resources and society. First, water is an very important resource for society in that it provides an essential input to society's food supply chains. Secondly, it is an essential input to farmer livelihoods. About half of the families of the world still work in agriculture - albeit a declining proportion. Thirdly, farmers manage about 92% of the water consumed by society - including the blue water (surface and groundwater) for irrigation and the green water (effective rainfall) consumed on rainfed farms. They also account for about 66% of society's impacts on biodiversity and about 25% of emissions. Finally it will be argued that those who analyse allocation and management of water must recognise that farming practices and the decisions made by those who operate food supply chains - including corporates and those making public policy - must recognise that it is farmers and food consumers who determine how water is stewarded. It will be suggested that we need to understand that well informed consumers could be the regulators.

  18. Cost inefficiency under financial strain: a stochastic frontier analysis of hospitals in Washington State through the Great Recession. (United States)

    Izón, Germán M; Pardini, Chelsea A


    The importance of increasing cost efficiency for community hospitals in the United States has been underscored by the Great Recession and the ever-changing health care reimbursement environment. Previous studies have shown mixed evidence with regards to the relationship between linking hospitals' reimbursement to quality of care and cost efficiency. Moreover, current evidence suggests that not only inherently financially disadvantaged hospitals (e.g., safety-net providers), but also more financially stable providers, experienced declines to their financial viability throughout the recession. However, little is known about how hospital cost efficiency fared throughout the Great Recession. This study contributes to the literature by using stochastic frontier analysis to analyze cost inefficiency of Washington State hospitals between 2005 and 2012, with controls for patient burden of illness, hospital process of care quality, and hospital outcome quality. The quality measures included in this study function as central measures for the determination of recently implemented pay-for-performance programs. The average estimated level of hospital cost inefficiency before the Great Recession (10.4 %) was lower than it was during the Great Recession (13.5 %) and in its aftermath (14.1 %). Further, the estimated coefficients for summary process of care quality indexes for three health conditions (acute myocardial infarction, pneumonia, and heart failure) suggest that higher quality scores are associated with increased cost inefficiency.

    Full Text Available Beginning with a characterization of contemporaneity (dominance of the financial sector and high technology, politicization of economy, ideological use of culture and control of the capacity for thought and a brief analysis of expansionism (political, economic, cultural on the eve of the Great War, the author embarks on a more detailed description of the spiritual situation in the wake of the Great War: in philosophy, literature, art, as well as the national-political programmatic texts and war propaganda publications of German intellectuals of the time. The continuity of the Austro-Hungarian colonial policy towards the Balkans and Serbia culminates in instigating a preventive war against Serbia by the elites in Berlin and Vienna, which is of importance with regard to the question of responsibility for the war, guided by concrete aims of war in which causes for war are reflected. These war elites wanted to declare the assassination in Sarajevo as the cause of war, which in fact was a political assassination and tyrannicide. The freedom movement of democratic youth, Mlada Bosna (Young Bosnia, needs to be viewed in the European context as inspired by the Serbian tradition of the cult of Kosovo and the ethics of Vidovdan (St Vitus' Day which speaks both about the victim's sacrifice as sublimation of history and about just suffering as elements of identity. Historical memory suggests that historical responsibility is transgenerational. The epic proportions of Serbian suffering in the Great War have additionally encouraged the positing of the theme of St Vitus' Day Temple (Vidovdanski Hram as envisaged by Ivan Meštrović. The foundations of this idea were shaken by Miloš Crnjanski who, in his 'Lyrics of Ithaca', succeeds in returning to Vidovdan (St Vitus' Day the inexhaustible national power of validity.

  2. [The Great Rift Valley. Parasitological results]. (United States)

    Nozais, J P


    East Africa is separated from the continent by the Great Rift Valley which was created at the end of the secondary era limiting then the East Africa under-continent with peculiar fauna and flora features. A several million years long isolation, during the tertiary era, seems to explain that a certain number of protozoan and helminthic diseases present peculiar clinical, epidemiological, therapeutical and parasitological features. The occurrence of those peculiar strains tends to indicate that in this region, for example, the resistance of P. falciparum to amino-4-quinolines is a regional feature which should not largely expand to the rest of the African continent.

  3. Commentary. The diseases of Alexander the Great. (United States)

    York, George K; Steinberg, David A


    The accompanying articles that speculate that Alexander the Great had a traumatic carotid dissection or congenital cervical scoliosis demonstrate the difficulties in retrospective diagnosis as a historical enterprise. The extant primary sources were written centuries after Alexander's death and are ambiguous in their original languages, and even more so in translation. Thus we cannot be certain what illness Alexander actually had. Furthermore, anachronistic diagnosis removes Alexander from the medical context of this time, telling us little of historical significance about him. Such investigations also illustrate the more general limits that the absence of context imposes on the study of ancient history.

In this paper, a graphical method (GM is proposed to solve the GCR problems based on the celestial meridian diagram (CMD in celestial navigation. Unlike developed algebraic methods, the GM is a geometric method. Appling computer software to graph, the GM does not use any equations but is as accurate as using algebraic methods. In addition, the GM, which emphasizes the rotational surface, can depict a GCR and judge its benefit.

    The public opinion always kept complex relations with the atom, done of fascination and repulsion. Is it then correct to speak of ''great fear of nuclear''? To answer this question the author presents, in five chapters, an analysis of the relations between the public and the nuclear. The two first chapters are devoted to historical aspects with respectively a presentation of the atomic episodes and the ground traumatisms. The chapters three and four presents the fears of the nuclear policy and the civil nuclear. The last chapter deals with the the fear of the military nuclear. (A.L.B.)

    Canada has a great national asset in its ability to generate electricity economically from its abundant hydro, coal, and uranium resources. Its nuclear industry has an excellent product. Despite lack of orders for now, the CANDU will be a competitive force when the reactor market recovers. Canada has a proven record of reliability for electricity trade with the United States. There appear to be some opportunities for plants in Canada dedicated to the export of electric power. The federal government is prepared to work closely with the provinces to develop projects which will be attractive to customers in the United States

  9. Properties of tooth enamel in great apes. (United States)

    Lee, James J-W; Morris, Dylan; Constantino, Paul J; Lucas, Peter W; Smith, Tanya M; Lawn, Brian R


    A comparative study has been made of human and great ape molar tooth enamel. Nanoindentation techniques are used to map profiles of elastic modulus and hardness across sections from the enamel-dentin junction to the outer tooth surface. The measured data profiles overlap between species, suggesting a degree of commonality in material properties. Using established deformation and fracture relations, critical loads to produce function-threatening damage in the enamel of each species are calculated for characteristic tooth sizes and enamel thicknesses. The results suggest that differences in load-bearing capacity of molar teeth in primates are less a function of underlying material properties than of morphology. Published by Elsevier Ltd.

  10. Overburndened and Underfunded: California Public Schools Amidst the Great Recession

    Directory of Open Access Journals (Sweden)

    Rhoda Freelon


    Full Text Available Since 2008, many nations, including the United States, have struggled with the effects of a global recession. The state of California has been particularly impacted by the Great Recession. Unemployment rates in California are among the highest in the United States, and a weak fiscal environment has forced deep cutbacks to a variety of state services. This study uses California as a case to explore the effects of economic crisis on public schools and the students they serve. The study draws on two years of survey and interview data with a representative sample of public school principals across California. The data show that, during the Great Recession, students have experienced growing social welfare needs that often shape their well-being and their performance in schools. We also find that the capacity of public schools to meet these needs and provide quality education has been eroded by budget cuts. This study finds that schools primarily serving low-income families have been hardest hit during the recession, in part because they cannot raise private dollars to fill the gap left by public sector cuts. The Great Recession thus has undermined educational quality while producing widening educational inequality in California.

  11. Great Western Malting Company geothermal project, Pocatello, Idaho. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Christensen, N.T.; McGeen, M.A.; Corlett, D.F.; Urmston, R.


    The Great Western Malting Company recently constructed a barley malting facility in Pocatello, Idaho, designed to produce 6.0 million bushels per year of brewing malt. This facility uses natural gas to supply the energy for germination and kilning processes. The escalating cost of natural gas has prompted the company to look at alternate and more economical sources of energy. Trans Energy Systems has investigated the viabiity of using geothermal energy at the new barley processing plant. Preliminary investigations show that a geothermal resource probably exists, and payback on the installation of a system to utilize the resource will occur in under 2 years. The Great Western Malting plant site has geological characteristics which are similar to areas where productive geothermal wells have been established. Geological investigations indicate that resource water temperatures will be in the 150 to 200/sup 0/F range. Geothermal energy of this quality will supply 30 to 98% of the heating requirements currently supplied by natural gas for this malting plant. Trans Energy Systems has analyzed several systems of utilizing the geothermal resource at the Great Western barley malting facility. These systems included: direct use of geothermal water; geothermal energy heating process water through an intermediary heat exchanger; coal or gas boosted geothermal systems; and heat pump boosted geothermal system. The analysis examined the steps that are required to process the grain.

  12. How to write a great business plan. (United States)

    Sahlman, W A


    Every seasoned investor knows that detailed financial projections for a new company are an act of imagination. Nevertheless, most business plans pour far too much ink on the numbers - and far too little on the information that really matters. Why? William Sahlman suggests that a great business plan is one that focuses on a series of questions. These questions relate to the four factors critical to the success of every new venture: the people, the opportunity, the context, and the possibilities for both risk and reward. The questions about people revolve around three issues: What do they know? Whom do they know? and How well are they known? As for opportunity, the plan should focus on two questions: Is the market for the venture's product or service large or rapidly growing (or preferably both)? and Is the industry structurally attractive? Then, in addition to demonstrating an understanding of the context in which their venture will operate, entrepreneurs should make clear how they will respond when that context inevitably changes. Finally, the plan should look unflinchingly at the risks the new venture faces, giving would-be backers a realistic idea of what magnitude of reward they can expect and when they can expect it. A great business plan is not easy to compose, Sahlman acknowledges, largely because most entrepreneurs are wild-eyed optimists. But one that asks the right questions is a powerful tool. A better deal, not to mention a better shot at success, awaits entrepreneurs who use it.

  13. Sedimentology of Great Sand Dunes, Colorado (United States)

    Andrews, Sarah


    Eolian and adjacent deposits of Great Sand Dunes Colorado form a small but sedimentologically complex deposit Eolian sediments can be subdivided into three provinces trending downwind northeast I low as much as 10 m high alkali cemented dunes forming discontinuous rings around broad flat bottomed ephemeral lakes II undulating vegetated dunes as high as 10 m of barchan parabolic shrub coppice and transverse type with varying interdune types III high as much as 200 m transverse dunes with little or no vegetation and no true interdune deposits Eolian deposits are in contact with or intercalated with fluvial lacustrine and alluvial fan deposits and lap onto crystalline basement rocks of the Sangre de Cristo Range. Analysis of a 40 year-span of aerial photographs and field observation of sand transport and cross bedding dip directions indicate that the main dune mass province III is accreting vertically and that dune types are growing in complexity in particular the star dunes This change from lateral migration to vertical growth most probably reflects Holocene changes in wind regime. The Great Sand Dunes are an example of a localized cool climate intermontane eolian deposit characterized by extensive fluvial reworking With its rapid variation in thicknesses sedimentary structures and associated sedimentary deposits such a deposit would be difficult to interpret accurately in the ancient rock record However such a deposit could be of economic importance in petroleum and uranium exploration and in aquifer evaluation

    International Nuclear Information System (INIS)

    Gkanoutas-Leventis, Angelos; Nesvetailova, Anastasia


    This article addresses the role of world oil price hike of 2007–08 in serving to transform the financial and banking crisis into what is commonly referred to the Great Recession. Existing literature on the global crisis of 2007–09 tends to view it as a financial or banking phenomenon, with analyses focusing mainly on state policies, governance mechanisms and market dynamics in transforming the banking crisis of 2007–08 into the economic recession of 2008-12/13 Although often attributing the global meltdown to wider phenomenon of financialisation, rarely do existing perspectives delve into the role of the commodity sector in the global credit crunch. In this paper, we aim to fill this gap, by inquiring into the role played by oil as a financial asset class in the political economy of the global crisis. - Highlights: • We study the oil price and its effects on the Great Recession. • We approach oil as a financial asset class. • We observe the transformation of oil through deregulation.

    Directory of Open Access Journals (Sweden)



    Full Text Available Traditionally, the economic international journalism has had in the Anglo-Saxon groups Dow Jones (USA and Pearson (Great Britain, publishers of The Wall Street and Financial Times respectively, his big world models. Nevertheless, the new century has brought enormous convulsions to the sector, to the newspapaers of elite and big agencies specialized in economic information as Reuters, Thomson or Bloomberg.

  16. Enriching Great Britain's National Landslide Database by searching newspaper archives (United States)

    Taylor, Faith E.; Malamud, Bruce D.; Freeborough, Katy; Demeritt, David


    Our understanding of where landslide hazard and impact will be greatest is largely based on our knowledge of past events. Here, we present a method to supplement existing records of landslides in Great Britain by searching an electronic archive of regional newspapers. In Great Britain, the British Geological Survey (BGS) is responsible for updating and maintaining records of landslide events and their impacts in the National Landslide Database (NLD). The NLD contains records of more than 16,500 landslide events in Great Britain. Data sources for the NLD include field surveys, academic articles, grey literature, news, public reports and, since 2012, social media. We aim to supplement the richness of the NLD by (i) identifying additional landslide events, (ii) acting as an additional source of confirmation of events existing in the NLD and (iii) adding more detail to existing database entries. This is done by systematically searching the Nexis UK digital archive of 568 regional newspapers published in the UK. In this paper, we construct a robust Boolean search criterion by experimenting with landslide terminology for four training periods. We then apply this search to all articles published in 2006 and 2012. This resulted in the addition of 111 records of landslide events to the NLD over the 2 years investigated (2006 and 2012). We also find that we were able to obtain information about landslide impact for 60-90% of landslide events identified from newspaper articles. Spatial and temporal patterns of additional landslides identified from newspaper articles are broadly in line with those existing in the NLD, confirming that the NLD is a representative sample of landsliding in Great Britain. This method could now be applied to more time periods and/or other hazards to add richness to databases and thus improve our ability to forecast future events based on records of past events.

  17. An integrated perspective on the Permian-Triassic "Great Dying" (United States)

    Algeo, T. J.


    The 252-Ma end-Permian mass extinction (EPME), marked by the loss of 90% of marine invertebrate species, was the largest biocrisis in Earth history. Intensive study of this "Great Dying" has led to major insights and a broad consensus regarding many aspects of this event. The ultimate trigger is regarded as eruption of the Siberian Traps Large Igneous Province (STLIP), which released large quantities of greenhouse gases (CO2 and CH4) and sulfate aerosols, triggering a catastrophic global warming of 10°C and acidification of both land surfaces and the surface ocean. On land, a massive die-off of vegetation led to a transient episode of rapid soil erosion and a longer-term increase in weathering rates linked to elevated temperatures. In the ocean, widespread anoxia developed concurrently with the EPME, triggered by ocean-surface warming that reduced dissolved oxygen solubility in seawater and that intensified vertical stratification. Expanded anoxia led to massive burial of organic matter and reduced sulfur, although the evidence for this is indirect (C, U and S isotopes); few organic-rich deposits of Early Triassic age have been found, suggesting that organic sedimentation occurred mainly on continental slopes or in the deep ocean. Other aspects of the end-Permian crisis remain under debate. For example, there is no consensus regarding changes in marine productivity levels in the aftermath of the EPME, which would have been stimulated by enhanced subaerial weathering but depressed by reduced overturning circulation-the evidence to date may favor localized positive and negative changes in productivity. Also under scrutiny is evidence for volcanic eruptions and environmental perturbations during the 100 kyr prior to the EPME, which are likely to have occurred but remain poorly dated and quantified. The greatest uncertainty, however, may surround the nature of the proximate kill mechanism(s) during the EPME. Many hypotheses have been advanced including mechanisms

  18. Mass Incarceration, Parental Imprisonment, and the Great Recession: Intergenerational Sources of Severe Deprivation in America

    Directory of Open Access Journals (Sweden)

    John Hagan


    Full Text Available What were the socioeconomic consequences for American youth of having a parent incarcerated during the 2008 Great Recession? We analyze a nationally representative panel study of adolescents who, when interviewed during this recession, were transitioning to and through early adulthood. Young adult children who have had a father or mother imprisoned are at increased risk of experiencing socioeconomic deprivation, including inadequate access to food. We build in this article on recent research showing that postsecondary education has become especially important in determining adult outcomes, and we demonstrate that higher educational attainment reduces intergenerational effects of parental imprisonment. The salient policy implication of this article may be the important protective role of education in reducing unprecedented risks and vulnerabilities imposed by mass parental incarceration.

    The scientific method is one of the most basic and essential concepts across the sciences, ensuring that investigations are carried out with precision and thoroughness. The scientific method is typically taught as a step-by-step approach, but real examples from history are not always given. This book teaches the basic modes of scientific thought, not by philosophical generalizations, but by illustrating in detail how great scientists from across the sciences solved problems using scientific reason. Examples include Christopher Columbus, Joseph Priestly, Antoine Lavoisier, Michael Faraday, W

  20. The death of Alexander the Great: malaria or typhoid fever? (United States)

    Cunha, Burke A


    Alexander the Great had a profound effect on world history. His conquests covered the entire known world at the time, and he was responsible for the spread of Greek culture throughout the ancient world. In Babylon in 323 BC, Alexander died when he was nearly 33 years old. Possible explanations for his death have included alcoholic liver disease and strychnine poisoning, but little data support either condition as the cause of his death. Alexander most likely died from malaria or typhoid fever, which were rampant in ancient Babylon. The description of his final illness from the royal diaries is consistent with typhoid fever or malaria but is most characteristic of typhoid fever.

  3. Leiomyosarcoma of the great saphenous vein

    Directory of Open Access Journals (Sweden)

    Alexandre Campos Moraes Amato


    Full Text Available A 56-year-old male patient presented with a complaint of two painful, hard, palpable nodules in the right lower limb. A Doppler ultrasound scan revealed the presence of nodules, likely to be neoplastic. Computed angiography showed two solid hypervascular nodules in the right great saphenous vein, fed by branches of the posterior tibial artery. Embolization of the nodules using surgical cyanoacrylate was performed, followed by an excisional biopsy. Anatomical pathology and immunohistochemical analysis identified the nodule as a high-grade leiomyosarcoma, characterized by ten mitotic figures per ten high-power fields, necrosis and cell pleomorphism. Immunohistochemical analysis results were positive for caldesmon and desmin labeling. A second surgical procedure was performed to enlarge the free margins.

  4. The Great Recession and Workers' Health Benefits. (United States)

    Koh, Kanghyock


    During a recession, cost-sharing of employer-sponsored health benefits could increase to reduce labor costs in the U.S. Using a variation in the severity of recession shocks across industries, I find evidence that the enrollment rate of high deductible health plans (HDHPs) among workers covered by employer-sponsored health benefits increased more among firms in industries that experienced severe recession shocks. As potential mechanisms, I study employer-side and worker-side mechanisms. I find that employers changed health benefit offerings to force or incentivize workers to enroll in HDHPs. But I find little evidence of an increase in workers' demand for HDHPs due to a reduction in income. These results suggest that the HDHP enrollment rate increased during the Great Recession, as employers tried to save costs of offering health benefits. Copyright © 2018 Elsevier B.V.

  5. Intimate Partner Violence in the Great Recession. (United States)

    Schneider, Daniel; Harknett, Kristen; McLanahan, Sara


    In the United States, the Great Recession was marked by severe negative shocks to labor market conditions. In this study, we combine longitudinal data from the Fragile Families and Child Wellbeing Study with U.S. Bureau of Labor Statistics data on local area unemployment rates to examine the relationship between adverse labor market conditions and mothers' experiences of abusive behavior between 2001 and 2010. Unemployment and economic hardship at the household level were positively related to abusive behavior. Further, rapid increases in the unemployment rate increased men's controlling behavior toward romantic partners even after we adjust for unemployment and economic distress at the household level. We interpret these findings as demonstrating that the uncertainty and anticipatory anxiety that go along with sudden macroeconomic downturns have negative effects on relationship quality, above and beyond the effects of job loss and material hardship.

  6. ROV dives under Great Lakes ice (United States)

    Bolsenga, S.J.; Gannon, John E.; Kennedy, Gregory; Norton, D.C.; Herdendorf, Charles E.


    Observations of the underside of ice have a wide variety of applications. Severe under-ice roughness can affect ice movements, rough under-ice surfaces can scour the bottom disturbing biota and man-made structures such as pipelines, and the flow rate of rivers is often affected by under-ice roughness. A few reported observations of the underside of an ice cover have been made, usually by cutting a large block of ice and overturning it, by extensive boring, or by remote sensing. Such operations are extremely labor-intensive and, in some cases, prone to inaccuracies. Remotely operated vehicles (ROV) can partially solve these problems. In this note, we describe the use, performance in a hostile environment, and results of a study in which a ROV was deployed under the ice in Lake Erie (North American Great Lakes).

  7. Including gauge corrections to thermal leptogenesis

    International Nuclear Information System (INIS)

    Huetig, Janine


    . Furthermore, we have computed the Majorana neutrino production rate itself in chapter 6 to test our numerical procedure. In this context we have calculated the tree-level result as well as the gauge corrected result for the Majorana neutrino production rate. Finally in chapter 7, we have implemented the Majorana neutrino ladder rung diagram into our setup for leptogenesis: As a first consideration, we have collected all gauge corrected diagrams up to three-loop order for the asymmetry-causing two-loop diagrams. However, the results of chap. 5 showed that it is not sufficient to just include diagrams up to three-loop level. Due to the necessity of resumming all n-loop diagrams, we have constructed a cylindrical diagram that fulfils this condition. This diagram is the link between the Majorana neutrino ladder rung diagram calculated before on the one hand and the lepton asymmetry on the other. Therefore we have been able to derive a complete expression for the integrated lepton number matrix including all leading order corrections. The numerical analysis of this lepton number matrix needs a great computational effort since for the resulting eight-dimensional integral two ordinary differential equations have to be computed for each point the routine evaluates. Thus the result remains yet inaccessible. Research perspectives: Summarising, this thesis provides the basis for a systematic inclusion of gauge interactions in thermal leptogenesis scenarios. As a next step, one should evaluate the expression for the integrated lepton number numerically to gain a value, which can be used for comparison to earlier results such as the solutions of the Boltzmann equations as well as the Kadanoff-Baym ansatz with the implemented Standard Model widths. This numerical result would be the first quantitative number, which contains leading order corrections due to all interactions of the Majorana neutrino with the Standard Model particles. Further corrections by means of including washout effects

  8. Microbial mat mineralization in Great Salt Lake (Utah, USA) (United States)

    PACE, Aurélie; Bouton, Anthony; Bourillot, Raphaël; Vennin, Emmanuelle; Visscher, Pieter; Dupraz, Christophe; Thomazo, Christophe; Serge, Galaup; Sophie, Leleu; Anna, Kwasniewski; Léa, Pigot; Michel, Franceschi


    Great Salt Lake is located in the Basin and Range province of Utah (USA). Its average surface is 4480 Km2 and its maximum depth is of about 15m. It is a partly rainfed endorheic hypersaline lake (average salinity: 140g/L). Due to the high salinity, little or no grazing organisms are present, favoring the development of microbialites that cover the margin of the lake. This work aims to understand the products and processes of mineralization in recent and modern microbialites on the western margin of Antelope Island. The distribution of microbialites and their morphology has been studied along lakeshore to center transects, showing a contrasting spatial distribution in bay versus headland. Fossil microbialites show a great diversity of macro- and microfabrics, some microbialites being essentially built by microbial-mediated carbonate precipitation, while other show the predominance of trapping and binding processes. The nature and composition of the microbial carbonates have been determined through polarizing, cathodoluminescence, reflected fluorescence microscopy, X-Ray diffractometry and isotope geochemistry (δ 18O and δ13C) in order to investigate the preservation of environmental signals in microbialites. Petrophysics analysis such as permeability and porosimetry, have been done to observe the structure of the microbialite. Microprobe and silver foils method have been used respectively to characterize oxygen production and sulfate reduction in living microbial mats. Mineralization zones seem to coincide with sulfate reduction hotspots. This mineralization results in mixed clotted-laminated fabric at the macro- and microscale. Several analysis such as Cryo-SEM, environmental SEM and raman spectroscopy three phases of mineralization allowed us to distinguish three type of minerals inside the mat: (1) a Mg and Si-rich clay developing on the organic matrix; (2) an intracellular Al-rich clay. (3) aragonite clots replacing the organic matrixes and embedding bacteria

  9. Structural investigations of Great Basin geothermal fields: Applications and implications

    Energy Technology Data Exchange (ETDEWEB)

    Faulds, James E [Nevada Bureau of Mines and Geology, Univ. of Nevada, Reno, NV (United States); Hinz, Nicholas H. [Nevada Bureau of Mines and Geology, Univ. of Nevada, Reno, NV (United States); Coolbaugh, Mark F [Great Basin Center for Geothermal Energy, Univ. of Nevada, Reno, NV (United States)


    Because fractures and faults are commonly the primary pathway for deeply circulating hydrothermal fluids, structural studies are critical to assessing geothermal systems and selecting drilling targets for geothermal wells. Important tools for structural analysis include detailed geologic mapping, kinematic analysis of faults, and estimations of stress orientations. Structural assessments are especially useful for evaluating geothermal fields in the Great Basin of the western USA, where regional extension and transtension combine with high heat flow to generate abundant geothermal activity in regions having little recent volcanic activity. The northwestern Great Basin is one of the most geothermally active areas in the USA. The prolific geothermal activity is probably due to enhanced dilation on N- to NNE-striking normal faults induced by a transfer of NW-directed dextral shear from the Walker Lane to NW-directed extension. Analysis of several geothermal fields suggests that most systems occupy discrete steps in normal fault zones or lie in belts of intersecting, overlapping, and/or terminating faults. Most fields are associated with steeply dipping faults and, in many cases, with Quaternary faults. The structural settings favoring geothermal activity are characterized by subvertical conduits of highly fractured rock along fault zones oriented approximately perpendicular to the WNW-trending least principal stress. Features indicative of these settings that may be helpful in guiding exploration for geothermal resources include major steps in normal faults, interbasinal highs, groups of relatively low discontinuous ridges, and lateral jogs or terminations of mountain ranges.

  11. A GREAT search for Deuterium in Comets (United States)

    Mumma, Michael


    Comets are understood to be the most pristine bodies in the Solar System. Their compositions reflect the chemical state of materials at the very earliest evolutionary stages of the protosolar nebula and, as such, they provide detailed insight into the physical and chemical processes operating in planet-forming disks. Isotopic fractionation ratios of the molecular ices in the nucleus are regarded as signatures of formation processes. These ratios provide unique information on the natal heritage of those ices, and can also test the proposal that Earth's water and other volatiles were delivered by cometary bombardment. Measurement of deuterium fractionation ratios is thus a major goal in contemporary cometary science and the D/H ratio of water - the dominant volatile in comets - holds great promise for testing the formation history of cometary matter. The D/H ratio in cometary water has been measured in only eight comets. Seven were from the Oort Cloud reservoir and the D/H ratio was about twice that of the Earth's oceans. However, the recent Herschel measurement of HDO/H2O in 103P/Hartley-2 (the first from the Kuiper Belt) was consistent with exogenous delivery of Earth's water by comets. Outstanding questions remain: are cometary HDO/H2O ratios consistent with current theories of nebular chemical evolution or with an interstellar origin? Does the HDO/H2O ratio vary substantially among comet populations? Hartley-2 is the only Kuiper Belt comet with measured HDO/H2O, are there comets with similar ratios in the Oort cloud? These questions can only be addressed by measuring HDO/H2O ratios in many more suitable bright comets. We therefore propose to measure the D/H ratio in water in a suitable target-of-opportunity comet by performing observations of HDO and OH with the GREAT spectrometer on SOFIA. A multi-wavelength, ground-based observing campaign will also be conducted in support of the airborne observations.

  12. Broadcast spawning by Pocillopora species on the Great Barrier Reef. (United States)

    Schmidt-Roach, Sebastian; Miller, Karen J; Woolsey, Erika; Gerlach, Gabriele; Baird, Andrew H


    The coral genus Pocillopora is one of the few to include some species that broadcast spawn gametes and some species that brood larvae, although reports of reproductive mode and timing vary within and among species across their range. Notably, the ubiquitous Pocillopora damicornis has been described as both a brooder and spawner, although evidence of broadcast spawning is rare. Here, we report observations of broadcast-spawning in four species of Pocillopora on the Great Barrier Reef (GBR), including P. damicornis. All species spawned predictably during the early morning, two days following the full moon, and spawning was observed in multiple months over the summer period (November to February). Eggs and sperm were free-spawned concurrently. Eggs were negatively buoyant and contained Symbiodinium. This newfound knowledge on the mode, timing and regularity of broadcast spawning in Pocillopora spp. on the GBR brings us one step closer to elucidating the complex reproductive ecology of these species.

  13. Oxygenation as a driver of the Great Ordovician Biodiversification Event (United States)

    Edwards, Cole T.; Saltzman, Matthew R.; Royer, Dana L.; Fike, David A.


    The largest radiation of Phanerozoic marine animal life quadrupled genus-level diversity towards the end of the Ordovician Period about 450 million years ago. A leading hypothesis for this Great Ordovician Biodiversification Event is that cooling of the Ordovician climate lowered sea surface temperatures into the thermal tolerance window of many animal groups, such as corals. A complementary role for oxygenation of subsurface environments has been inferred based on the increasing abundance of skeletal carbonate, but direct constraints on atmospheric O2 levels remain elusive. Here, we use high-resolution paired bulk carbonate and organic carbon isotope records to determine the changes in isotopic fractionation between these phases throughout the Ordovician radiation. These results can be used to reconstruct atmospheric O2 levels based on the O2-dependent fractionation of carbon isotopes by photosynthesis. We find a strong temporal link between the Great Ordovician Biodiversification Event and rising O2 concentrations, a pattern that is corroborated by O2 models that use traditional carbon-sulfur mass balance. We conclude that that oxygen levels probably played an important role in regulating early Palaeozoic biodiversity levels, even after the Cambrian Explosion.

  14. Regional Personality Differences in Great Britain (United States)

    Rentfrow, Peter J.; Jokela, Markus; Lamb, Michael E.


    Recent investigations indicate that personality traits are unevenly distributed geographically, with some traits being more prevalent in certain places than in others. The geographical distributions of personality traits are associated with a range of important political, economic, social, and health outcomes. The majority of research on this subject has focused on the geographical distributions and macro-level correlates of personality across nations or regions of the United States. The aim of the present investigation was to replicate and extend that past work by examining regional personality differences in Great Britain. Using a sample of nearly 400,000 British residents, we mapped the geographical distributions of the Big Five Personality traits across 380 Local Authority Districts and examined the associations with important political, economic, social, and health outcomes. The results revealed distinct geographical clusters, with neighboring regions displaying similar personality characteristics, and robust associations with the macro-level outcome variables. Overall, the patterns of results were similar to findings from past research. PMID:25803819

  15. What makes CERN’s research great

    CERN Multimedia


    As a newcomer to CERN, I find myself both honoured and humbled to have had the role of Research Director confided in me for five years.    My career has taken me from Hamburg to Stanford and Heidelberg and back to Hamburg, and although this is the first time I have been based at CERN, it is not my first involvement with the Laboratory. I was a member of the OPAL collaboration in the late 1980s, and chaired the LHCC from 2011 to 2014. In addition, over the past ten years I have enjoyed contacts with many colleagues at CERN, via joint European programmes and particularly in discussions on linear colliders. In this, my first message to personnel, I’d like to set out my view of what makes CERN’s research great, and where I’d like to see things when I step down at the end of 2020. First and foremost, I have to refer to the many excellent experts at CERN and to the thousands of users of our facilities. Their ideas are the backbone of all...

  16. Critical metals in the great transformation

    International Nuclear Information System (INIS)

    Exner, Andreas; Held, Martin; Kuemmerer, Klaus


    The book broadens the view on the short-term availability of critical metals to the fundamental question: critical for whom? The authors take all stakeholders into consideration and deal with geological, chemical, technical, economic and social aspects as well as questions of recycling. They also address questions of good life and mining from the perspective of countries of the South, questions of resource policy and justice. A further topic is the UN deep-sea mining regime and its perspectives on how unconventional ore from the deep-sea can be won in the future. Critical metals are classified into the overlapping context of the upcoming Great Transformation. The book examines in particular the fundamental importance of the material prerequisites of the energy transition and the energetic prerequisites of the material turnaround as well as the digitization. This shows that not only rare earths are critical, but also industrial metals such as copper. Resource policy aims, among other things, to secure primary supplies of technology metals, resource efficiency, recycling and substitution of critical substances. Despite the first successes, the dynamics are still unbroken in the direction of an increasing dissipation of valuable critical metals. What is needed is a rapid reversal with the aim of no longer consuming critical metals on a grand scale, but of using them wisely. [de

  17. Climate index for Great Britain - Methodology

    International Nuclear Information System (INIS)


    According to the U.S. Department of Energy, an estimated 25% of the GNP is affected by weather-related events. The variations in temperature - even small ones - can also have long-lasting effects on the operational results of a company. Among other, the Energy supply sector is sensitive to weather risks: a milder or harsher than usual winter leads to a decrease or increase of energy consumption. The price of electricity on power trading facilities like Powernext is especially sensitive to odd changes in temperatures. Powernext and Meteo-France (the French meteorological agency) have joined expertise in order to promote the use of weather indices in term of decision making or underlying of hedging tools to energy actors, end users from any other sector of activity and specialists of the weather risk hedging. The Powernext Weather indices are made from information collected by Meteo-France's main observation network according to the norms of international meteorology, in areas carefully selected. The gross data are submitted to a thorough review allowing the correction of abnormalities and the reconstitution of missing data. Each index is fashioned to take into account the economic activity in the various regions of the country as represented by each region's population. This demographic information represents a fair approximation of the weight of the regional economic activity. This document presents the calculation methodology of average, minimum and maximum weather indexes with the winter and summer regression equations for the different economical regions of Great Britain.

  18. Material Stock Demographics: Cars in Great Britain. (United States)

    Cabrera Serrenho, André; Allwood, Julian M


    Recent literature on material flow analysis has been focused on quantitative characterization of past material flows. Fewer analyses exist on past and prospective quantification of stocks of materials in-use. Some of these analyses explore the composition of products' stocks, but a focus on the characterization of material stocks and its relation with service delivery is often neglected. We propose the use of the methods of human demography to characterize material stocks, defined herein as stock demographics, exploring the insights that this approach could provide for the sustainable management of materials. We exemplify an application of stock demographics by characterizing the composition and service delivery of iron, steel, and aluminum stocks of cars in Great Britain, 2002-2012. The results show that in this period the stock has become heavier, it is traveling less, and it is idle for more time. The visualization of material stocks' dynamics demonstrates the pace of product replacement as a function of its usefulness and enables the formulation of policy interventions and the exploration of future trends.

  19. [Contracts including performance and management of uncertainty]. (United States)

    Duru, G; Garassus, P; Auray, J-P


    Since many decades in France, the most important part of ambulatory health care expenditure is represented by drug consumption. By the fact, French patient is indeed the greatest world consumer of pharmaceuticals treatments. Therefore, the regulation authorities by successive strategies, attempt to limit or even restrict market access for new drugs in the health care sector secured by public social insurance coverage. Common objectives are to assess the reimbursement to scientific studies and to fix the price of therapeutics at an acceptable level for both industries and government. New trends try then to determine recently the drug price in a dual approach, as a component of global and effective contract, including performance and outcome. The first diffusion authorization is diffusion concerned, but this concept takes into account the eventual success of new produces in long-term survey. Signed for a fixed period as reciprocal partnership between regulation authorities and pharmaceutics industries, the contract integrates two dimensions of incertitude. The first one is represented by the strategy of new treatments development according to efficacy and adapted price, and the second one is linked to the result of diffusion and determines adapted rules if eventual non-respects of the previous engagement are registered. This paper discusses problems related to this new dimension of incertitude affected by conditional drug prices in market access strategy and the adapted follow-up of new treatment diffusion fixed by "outcome" contract between French regulation administration and pharmaceutics industries in our recent economic context.

  20. Air pollution and environmental justice in the Great Lakes region (United States)

    Comer, Bryan

    While it is true that air quality has steadily improved in the Great Lakes region, air pollution remains at unhealthy concentrations in many areas. Research suggests that vulnerable and susceptible groups in society -- e.g., minorities, the poor, children, and poorly educated -- are often disproportionately impacted by exposure to environmental hazards, including air pollution. This dissertation explores the relationship between exposure to ambient air pollution (interpolated concentrations of fine particulate matter, PM2.5) and sociodemographic factors (race, housing value, housing status, education, age, and population density) at the Census block-group level in the Great Lakes region of the United States. A relatively novel approach to quantitative environmental justice analysis, geographically weighted regression (GWR), is compared with a simplified approach: ordinary least squares (OLS) regression. While OLS creates one global model to describe the relationship between air pollution exposure and sociodemographic factors, GWR creates many local models (one at each Census block group) that account for local variations in this relationship by allowing the value of regression coefficients to vary over space, overcoming OLS's assumption of homogeneity and spatial independence. Results suggest that GWR can elucidate patterns of potential environmental injustices that OLS models may miss. In fact, GWR results show that the relationship between exposure to ambient air pollution and sociodemographic characteristics is non-stationary and can vary geographically and temporally throughout the Great Lakes region. This suggests that regulators may need to address environmental justice issues at the neighborhood level, while understanding that the severity of environmental injustices can change throughout the year.

  1. Africa's Great Green Wall Initiative: a model for restoration success (United States)

    Berrahmouni, Nora; Sacande, Moctar


    The Great Green Wall for the Sahara and the Sahel Initiative was launched to address the increasing challenges of land degradation, desertification and drought, climate change, food insecurity and poverty in more than 20 countries. Restoration of agro-sylvo-pastoral landscapes and degraded lands is one of the priority interventions initiated, enabling the springing up of green nests of life. When complete, the Great Green Wall of Africa will reverse the seemingly unstoppable desertification and address the development of its drylands' inhabitant rural communities. Today's planting of modest seedlings will grow into vast mosaics of forest and agroforestry landscapes and grasslands, which will provide essential ecosystem goods and services, restore lost livelihoods and create new wealth. The ambition of reforestation efforts within this initiative - the like of which the world has never seen before - sounds like an impossible dream. However, learning from past mistakes and capitalising on current advancement in science and technology, it is a reality that is taking root. Following a successful restoration model that RBG Kew experts have devised, we are helping to mobilise, train and support communities in four border regions in Burkina Faso, Mali and Niger. In collaboration with FAO, the Millennium Seed Bank Partnership is using its unique expertise to ensure that seeds of environmentally well-adapted and economically useful local species are collected and planted in communal gardens and village agroforestry systems managed by the communities themselves. In our first year, an estimated total of 162,000 seedlings and 61 kg of seeds from 40 useful native species, including grasses for livestock, have been planted to cover 237 ha of farmer-managed land in 19 villages. The keen interest it has created has indicated that these figures will rise five-fold in the second year. These green bricks are the foundations of the living wall that will eventually reach across the

  2. Information seeking about tool properties in great apes. (United States)

    Bohn, Manuel; Allritz, Matthias; Call, Josep; Völter, Christoph J


    Evidence suggests that great apes engage in metacognitive information seeking for food items. To support the claim that a domain-general cognitive process underlies ape metacognition one needs to show that selective information seeking extends to non-food items. In this study, chimpanzees (Pan troglodytes) and orangutans (Pongo abelii) either had to determine the location of a desired food item or a property of a non-food item (length of a tool). We manipulated whether subjects received prior information about the item's location or property. During the test, subjects had the opportunity to seek the respective information. Results show that apes engaged in more information seeking when they had no prior knowledge. Importantly, this selective pattern of information seeking applied to food as well as to tools.

  3. Conceiving and Marketing NASA's Great Observatories (United States)

    Harwit, Martin


    In late 1984, Dr. Charles P. (Charlie) Pellerin Jr., director of the Astrophysics Division of NASA's Office of Space Science and Applications (OSSA) faced a dilemma. Congress and the White House had given approval to work that would lead to the launch of the Gamma Ray Observatory and the Hubble Space Telescope, but competing segments of the astronomical community were clamoring for two additional missions, the Space Infrared Telescope Facility (SIRTF) and the Advanced X-ray Astrophysics Facility (AXAF). Pellerin knew that Congress would not countenance a request for another costly astronomical space observatory so soon after approving GRO and HST. He also foresaw that if he arbitrarily assigned priority to either AXAF or SIRTF he would split the astronomical community. The losing faction would be up on Capitol Hill, lobbying Congress to reverse the decision; and Congress would do what it always does with split communities --- nothing. Pellerin called a meeting of leading astrophysicists to see how a persuasive argument could be made for both these new observatories and to market them as vital to a first comprehensive inventory of the universe conducted across all wavelength ranges. The group provided Pellerin a rotating membership of astrophysicists, who could debate and resolve issues so that decisions he reached would have solid community support. It also helped him to market his ideas in Congress. Ultimately, the concept of the Great Observatories came to be accepted; but its implementation faced myriad difficulties. False starts, political alliances that never worked out, and dramatic changes of direction necessitated by the Challenger disaster of early 1986 continually kept progress off balance. My paper follows these twists and turns from late 1984 to the announcement, on February 1, 1988, that President Reagan's FY89 budget proposal to Congress had designated AXAF for a new start.

  4. Sequential tool use in great apes.

    Directory of Open Access Journals (Sweden)

    Gema Martin-Ordas

    Full Text Available Sequential tool use is defined as using a tool to obtain another non-food object which subsequently itself will serve as a tool to act upon a further (subgoal. Previous studies have shown that birds and great apes succeed in such tasks. However, the inclusion of a training phase for each of the sequential steps and the low cost associated with retrieving the longest tools limits the scope of the conclusions. The goal of the experiments presented here was, first to replicate a previous study on sequential tool use conducted on New Caledonian crows and, second, extend this work by increasing the cost of retrieving a tool in order to test tool selectivity of apes. In Experiment 1, we presented chimpanzees, orangutans and bonobos with an out-of-reach reward, two tools that were available but too short to reach the food and four out-of-reach tools differing in functionality. Similar to crows, apes spontaneously used up to 3 tools in sequence to get the reward and also showed a strong preference for the longest out-of reach tool independently of the distance of the food. In Experiment 2, we increased the cost of reaching for the longest out-of reach tool. Now apes used up to 5 tools in sequence to get the reward and became more selective in their choice of the longest tool as the costs of its retrieval increased. The findings of the studies presented here contribute to the growing body of comparative research on tool use.

  5. Woody riparian vegetation of Great Basin National Park. Interim report

    Energy Technology Data Exchange (ETDEWEB)

    Douglas, C.L.; Smith, S.D.; Murray, K.J.; Landau, F.H.; Sala, A.


    The community composition and population structure of the woody riparian vegetation in Great Basin National Park are described. Community analyses were accomplished by sampling 229 plots placed in a systematic random fashion along elevational gradients of 8 major stream systems (Baker, Big Wash, Lehman, Pine, Pole, Shingle, Snake, and Strawberry Creeks) in the Park using the releve method. Stand demographics were determined for the four dominant tree species in the Park, based on absolute stem counts at 15 sites along 6 major watersheds. Elevational ranges of the dominant tree and shrub species along 8 major streams were determined via transect analysis and systematic reconnaissance efforts. TWINSPAN (two-way indicator analysis) indentified 4 primary species groups and 8 stand groups in the Park. Because of the homogeneity of riparian zones, both presence and abundance of species were important parameters in determining species groups. Although species such as Populus tremuloides (aspen), Abies concolor (white fir) and Rosa woodsii (Woods rose) are very common throughout the Park, they are particularly abundant at higher, upper intermediate, and lower intermediate elevations.

  6. Predicting transmission of structure-borne sound power from machines by including terminal cross-coupling

    DEFF Research Database (Denmark)

    Ohlrich, Mogens


    strength and the prediction of power transmission to a supporting structure or the machine casing itself can be greatly simplified if all mobility cross-terms and spatial cross-coupling of source velocities can be neglected in the analysis. In many cases this gives an acceptable engineering accuracy......, especially at mid- and high-frequencies. For structurally compact machines, however, the influence of cross-coupling cannot always be ignored. The present paper addresses this problem and examines the transmission of structure-borne sound power by including spatial cross-coupling between pairs......Structure-borne sound generated by audible vibration of machines in vehicles, equipment and house-hold appliances is often a major cause of noise. Such vibration of complex machines is mostly determined and quantified by measurements. It has been found that characterization of the vibratory source...

  8. Use of Fish Telemetry in Rehabilitation Planning, Management, and Monitoring in Areas of Concern in the Laurentian Great Lakes (United States)

    Brooks, J. L.; Boston, C.; Doka, S.; Gorsky, D.; Gustavson, K.; Hondorp, D.; Isermann, D.; Midwood, J. D.; Pratt, T. C.; Rous, A. M.; Withers, J. L.; Krueger, C. C.; Cooke, S. J.


    Freshwater ecosystems provide many ecosystem services; however, they are often degraded as a result of human activity. To address ecosystem degradation in the Laurentian Great Lakes, Canada and the United States of America established the Great Lakes Water Quality Agreement (GLWQA). In 1987, 43 highly polluted and impacted areas were identified under the GLWQA as having one or more of 14 Beneficial Use Impairments (BUIs) to the physical and chemical habitat for fish, wildlife and humans, and were designated as Areas of Concern (AOC). Subnational jurisdictions combined with local stakeholders, with support from federal governments, developed plans to remediate and restore these sites. Biotelemetry (the tracking of animals using electronic tags) provides information on the spatial ecology of fish in the wild relevant to habitat management and stock assessment. Here, seven case studies are presented where biotelemetry data were directly incorporated within the AOC Remedial Action Plan (RAP) process. Specific applications include determining seasonal fish-habitat associations to inform habitat restoration plans, identifying the distribution of pollutant-indicator species to identify exposure risk to contamination sources, informing the development of fish passage facilities to enable fish to access fragmented upstream habitats, and assessing fish use of created or restored habitats. With growing capacity for fish biotelemetry research in the Great Lakes, we discuss the strengths and weaknesses of incorporating biotelemetry into AOC RAP processes to improve the science and practice of restoration and to facilitate the delisting of AOCs.

  10. Long-term Agroecosystem Research in the Northern Great Plains. (United States)

    Schmer, M.; Sanderson, M.; Liebig, M. A.; Wienhold, B.; Awada, T.; Papiernik, S.; Osborne, S.; Kemp, W.; Okalebo, J. A.; Riedall, W.


    The Northern Great Plains is the bread basket of the United States, accounting for a substantial portion of U.S. agricultural production. This region faces critical challenges regarding balancing food needs, resource conservation (e.g Ogallala aquifer), environmental concerns, and rural economy development. Developing transformative, multifunctional systems will require equally imaginative and efficient tools to help farmers manage complex agroecosystems in a rapidly changing climate. The Northern Plains long-term agroecosystem research (LTAR) site at Mandan, ND and the Platte River High Plains LTAR (ARS/University of Nebraska-Lincoln) at Lincoln, NE in collaboration with USDA-ARS research units in Brookings, SD and Fargo, ND are collaborating to address the grand challenge of providing and sustaining multiple service provisions from Northern Great Plains agroecosystems. We propose to attain these goals through sustainable intensification based on the adoption of conservation agriculture principles including reduced soil disturbance, livestock integration, and greater complexity and diversity in the cropping system. Here, we summarize new concepts these locations have pioneered in dynamic cropping systems, resource use efficiency, and agricultural management technologies. As part of the LTAR network, we will conduct long-term cross-site research to design and assess new agricultural practices and systems aimed at improving our understanding of decision making processes and outcomes across an array of agricultural systems.

  11. The Seventh Great Cosmovision: Quantum Mechanics and Conscious Universe

    Directory of Open Access Journals (Sweden)

    Adolfo Castilla


    Full Text Available This paper deals with the very general and old theme, but at the same time a very current one, of differences and possible relationships between matter and spirit. It is done through the consideration of phenomena so call, «worldviews», or general interpretations of what is our world and what men do in it, which emerge periodically in humanity as a result of great discoveries and great explanatory theories on the nature of our universe, including man within him. It is suggested that we are entering the seventh «worldview» in the history of humankind and it is defined in general terms. The enhancement of humans in physiological and mental terms may be one of the concrete results of the new interpretations and technological changes that accompany them, as well as the pervasive use of Strong Artificial Intelligence, creation of humanoid robots and the construction of «spiritual Machines». More important than all this, and to what we refer especially, is the fact that the new stage of man before him, can be characterized by an increased role of spirit, consciousness, and subjectivity in the progress of our world, something to what new ideas related to Quantum Mechanics and the possibility of existence of a Conscious Universe contribute in an important manner.

  12. Frictional contrast controls timing and great earthquakes in southern Chile (United States)

    Moreno, M.; Li, S.; Melnick, D.; Bedford, J. R.; Baez, J. C., Sr.; Motagh, M.; Metzger, S.; Vajedian, S.; Sippl, C.; Contreras-Reyes, E.; Gutknecht, B. D.; Oncken, O.


    Many fundamental processes of the earthquake cycle in subduction zones, including those controlling the timing and size of great earthquakes, are still poorly understood. Here we use continuous GPS, differential interferometry and seismological data to analyze the 2016 southern Chile earthquake (Mw 7.6). This was the first >7.5 Mw event that occurred in the rupture zone of the 1960 earthquake (Mw 9.5), offering unique constraints on the material properties and mechanics of the seismogenic zone. The 2016 earthquake ruptured the deeper portion of a highly coupled asperity with most slip concentrated in the deeper segment of the seismogenic zone near the transition to the continental Moho. We find that the steady subduction of a coupled asperity induces accumulation of shear stress around its downdip border, where moderate-size seismic events uncouple the fault before the entire coupled area fails in a major event. We propose that the deeper segments of the seismogenic fault are strained and stressed during decades because of the transition between two regions of contrasting frictional behaviour. Mechanical modeling suggests that variations of the pore pressure controls frictional variations and thus the lag time between deeper, lower magnitude events, such as the 2016 earthquake, and shallower great to giant earthquakes. The frictional segmentation inferred from our model coincides with the presence of a forearc basin in the upper plate, suggesting that the segmentation may be persistent in time. Our results strengthen the understanding of the mechanics of asperities and their link to geologic and geomorphic features.

  13. Whooping crane stopover site use intensity within the Great Plains (United States)

    Pearse, Aaron T.; Brandt, David A.; Harrell, Wade C.; Metzger, Kristine L.; Baasch, David M.; Hefley, Trevor J.


    Whooping cranes (Grus americana) of the Aransas-Wood Buffalo population migrate twice each year through the Great Plains in North America. Recovery activities for this endangered species include providing adequate places to stop and rest during migration, which are generally referred to as stopover sites. To assist in recovery efforts, initial estimates of stopover site use intensity are presented, which provide opportunity to identify areas across the migration range used more intensively by whooping cranes. We used location data acquired from 58 unique individuals fitted with platform transmitting terminals that collected global position system locations. Radio-tagged birds provided 2,158 stopover sites over 10 migrations and 5 years (2010–14). Using a grid-based approach, we identified 1,095 20-square-kilometer grid cells that contained stopover sites. We categorized occupied grid cells based on density of stopover sites and the amount of time cranes spent in the area. This assessment resulted in four categories of stopover site use: unoccupied, low intensity, core intensity, and extended-use core intensity. Although provisional, this evaluation of stopover site use intensity offers the U.S. Fish and Wildlife Service and partners a tool to identify landscapes that may be of greater conservation significance to migrating whooping cranes. Initially, the tool will be used by the U.S. Fish and Wildlife Service and other interested parties in evaluating the Great Plains Wind Energy Habitat Conservation Plan.

  14. Delphi survey of issues after the Great East Japan Earthquake

    Maeda, Yasunobu; Seo, Kami; Motoyoshi, Tadahiro; Okada, Shinya


    The Great East Japan Earthquake on March 11, 2011 has catastrophic impacts on Japan. Japan is currently on the way to recovery. However, as the damage on the country as well as society is so serious, Japanese society is urged to change some systems including hazard management, energy policy, information systems and city planning. These changes are accompanied with social group realignments, thus necessarily followed by various risks. To cope with these risk issues, SRA-Japan established the special research committee for the Great East Japan Earthquake. The aim of the committee is, from viewpoints of risk analysts, to create and relate messages about risk issues in 2-3 years, in ten years and in thirty years from the earthquake. To do this, the committee garners SRA-Japan member's opinions about possible risks in Japan by using Delphi method. In SRA-Japan, there are over 600 members in interdisciplinary fields from various backgrounds, thus the messages are expected to be helpful for Japanese society to lower its risks and to optimize the resource allocation. The research is now underway. An interim report will be presented. (author)

  15. Ecotoxicology of organochlorine chemicals in birds of the Great Lakes (United States)

    Tillitt, Donald E.; Giesy, John P.


    Silent Spring was fulfilled in the United States with passage of environmental legislation such as the Clean Water Act, the Federal Insecticide, Fungicide, and Rodenticide Act, and the Toxic Substance Control Act in the 1970s. Carson's writings, television interviews, and testimony before Congress alerted a nation and the world to the unintended effects of persistent, bioaccumulative chemicals on populations of fish, wildlife, and possibly humans. Her writings in the popular press brought attention to scientific findings that declines in populations of a variety of birds were directly linked to the widespread use of dichlorodiphenyltrichloroethane (DDT) in agriculture, public health, and horticulture. By the 1970s, DDT and other persistent organic pollutants (POPs) were being banned or phased out, and the intent of these regulatory acts became apparent in a number of locations across the United States, including the Great Lakes. Concentrations of DDT and its major product of transformation, dichlorodiphenylchloroethane (DDE), were decreasing in top predators, such as bald eagles (Haliaeetus leucocephalus), osprey (Pandion haliaetus), colonial waterbirds, and other fish-eating wildlife. Eggshell thinning and the associated mortality of bird embryos caused by DDE had decreased in the Great Lakes and elsewhere by the early 1980s.

  16. Great Lakes Biomass State and Regional Partnership (GLBSRP)

    Energy Technology Data Exchange (ETDEWEB)

    Kuzel, Frederic


    The Council of Great Lakes Governors administered the Great Lakes Biomass State and Regional Partnership (GLBSRP) under contract with the U. S. Department of Energy (DOE). This Partnership grew out of the existing Regional Biomass Energy Program which the Council had administered since 1983. The GLBSRP includes the States of Illinois, Indiana, Iowa, Michigan, Minnesota, Ohio and Wisconsin. The GLBSRP's overall goal is to facilitate the increased production and use of bioenergy and biobased products throughout the region. The GLBSRP has traditionally addressed its goals and objectives through a three-pronged approach: providing grants to the States; undertaking region-wide education, outreach and technology transfer projects; and, providing in-house management, support and information dissemination. At the direction of US Department of Energy, the primary emphasis of the GLBSRP in recent years has been education and outreach. Therefore, most activities have centered on developing educational materials, hosting workshops and conferences, and providing technical assistance. This report summarizes a selection of activities that were accomplished under this cooperative agreement.

  9. Glial cell biology in the Great Lakes region. (United States)

    Feinstein, Douglas L; Skoff, Robert P


    We report on the tenth bi-annual Great Lakes Glial meeting, held in Traverse City, Michigan, USA, September 27-29 2015. The GLG meeting is a small conference that focuses on current research in glial cell biology. The array of functions that glial cells (astrocytes, microglia, oligodendrocytes, Schwann cells) play in health and disease is constantly increasing. Despite this diversity, GLG meetings bring together scientists with common interests, leading to a better understanding of these cells. This year's meeting included two keynote speakers who presented talks on the regulation of CNS myelination and the consequences of stress on Schwann cell biology. Twenty-two other talks were presented along with two poster sessions. Sessions covered recent findings in the areas of microglial and astrocyte activation; age-dependent changes to glial cells, Schwann cell development and pathology, and the role of stem cells in glioma and neural regeneration.

  10. The Great Recession and the Social Safety Net (United States)

    Moffitt, Robert A.


    The social safety net responded in significant and favorable ways during the Great Recession. Aggregate per capita expenditures grew significantly, with particularly strong growth in the SNAP, EITC, UI, and Medicaid programs. Distributionally, the increase in transfers was widely shared across demographic groups, including families with and without children, single-parent and two-parent families. Transfers grew as well among families with more employed members and with fewer employed members. However, the increase in transfer amounts was not strongly progressive across income classes within the low-income population, increasingly slightly more for those just below the poverty line and those just above it, compared to those at the bottom of the income distribution. This is mainly the result of the EITC program, which provides greater benefits to those with higher family earnings. The expansions of SNAP and UI benefitted those at the bottom of the income distribution to a greater extent. PMID:27065356

  11. Alexander the Great and West Nile virus encephalitis. (United States)

    Marr, John S; Calisher, Charles H


    Alexander the Great died in Babylon in 323 BC. His death at age 32 followed a 2-week febrile illness. Speculated causes of death have included poisoning; assassination, and a number of infectious diseases. One incident, mentioned by Plutarch but not considered by previous investigators, may shed light on the cause of Alexander's death. The incident, which occurred as he entered Babylon, involved a flock of ravens exhibiting unusual behavior and subsequently dying at his feet. The inexplicable behavior of ravens is reminiscent of avian illness and death weeks before the first human cases of West Nile virus infection were identified in the United States. We posit that Alexander may have died of West Nile virus encephalitis.

    Teo SH


    Full Text Available Tuberculosis (TB, once a disease confined to undeveloped or developing nations is currently in resurgence due to pandemic human immunodeficiency virus infection and immigration from endemic areas. TB is also known as the ‘great mimicker’. Extra-pulmonary tuberculosis affecting the knee is rare in all forms of TB (0.1-0.3%. Here, we report a case of isolated highly erosive TB knee in a previously fit Burmese migrant worker. He presented with after a history of fall into a drain. The patient also reported pain and swelling over his left knee for the previous three years. He had been treated for a bacterial infection of the knee in another hospital but defaulted due to financial constraints. Arthrotomy of the knee was performed including washout. Diagnosis of TB of the knee was made based on the synovial fluid and tissue culture. Treatment with anti- tuberculosis drugs was then initiated.

    Full Text Available Transposition of great arteries (TGA is one of the most common and severe congenital heart diseases (CHD. It is also one of the most mysterious CHD because it has no precedent in phylogenetic and ontogenetic development, it does not represent an alternative physiological model of blood circulation and its etiology and morphogenesis are still largely unknown. However, recent epidemiologic, experimental and genetic data suggest new insights into the pathogenesis. TGA is very rarely associated with the most frequent genetic syndromes, such as Turner, Noonan, Williams or Marfan syndromes, and in Down syndrome, it is virtually absent. The only genetic syndrome with a strong relation with TGA is Heterotaxy. Moreover, TGA is rather frequent in cases of isolated dextrocardia with situs solitus, showing link with defect of visceral situs. In lateralization defects TGA is frequently associated with asplenia syndrome. Nowadays, the most reliable method to induce TGA consists in treating pregnant mice with retinoic acid or with retinoic acid inhibitors. Following such treatment not only cases of TGA with d-ventricular loop have been registered, but also some cases of congenitally corrected transposition of great arteries (CCTGA. In another experiment, the embryos of mice treated with retinoic acid in day 6.5 presented Heterotaxy, suggesting a relationship among these morphologically different CHD. In some families, beside TGA cases, there were first-degree relatives with CCTGA. This data suggest that monogenic inheritance with a variable phenotypic expression could explain the familial aggregation of TGA and CCTGA. In some of these families we previously found multiple mutations in laterality genes including Nodal and ZIC3, confirming a pathogenetic relation between TGA and Heterotaxy. These overall data suggest to include TGA in the pathogenetic group of laterality defects instead of conotruncal abnormalities due to ectomesenchymal tissue migration.

  15. Cetaceans and Marine Debris: The Great Unknown

    Directory of Open Access Journals (Sweden)

    Mark Peter Simmonds


    Full Text Available Plastics and other marine debris have been found in the gastrointestinal tracts of cetaceans, including instances where large quantities of material have been found that are likely to cause impairment to digestive processes and other examples, where other morbidity and even death have resulted. In some instances, debris may have been ingested as a result of the stranding process and, in others, it may have been ingested when feeding. Those species that are suction or “ram” feeders may be most at risk. There is also evidence of entanglement of cetaceans in marine debris. However, it is usually difficult to distinguish entanglement in active fishing gear from that in lost or discarded gear. The overall significance of the threat from ingested plastics and other debris remains unclear for any population or species of cetaceans, although there are concerns for some taxa, including at the population level, and marine debris in the oceans continues to grow. Further research including the compilation of unpublished material and the investigation of important habitat areas is strongly recommended.

  16. Managing mercury in the great lakes: an analytical review of abatement policies. (United States)

    Mohapatra, Satya P; Nikolova, Iana; Mitchell, Anne


    Mercury, a toxic metal known to have several deleterious affects on human health, has been one of the principal contaminants of concern in the Great Lakes basin. There are numerous anthropogenic sources of mercury to the Great Lakes area. Combustion of coal, smelting of non ferrous metals, and incineration of municipal and medical waste are major sources of mercury emissions in the region. In addition to North American anthropogenic emissions, global atmospheric emissions also significantly contribute to the deposition of mercury in the Great Lakes basin. Both the USA and Canada have agreed to reduce human exposure to mercury in the Great Lakes basin and have significantly curtailed mercury load to this region through individual and joint efforts. However, many important mercury sources, such as coal-fired power plants, still exist in the vicinity of the Great Lakes. More serious actions to drastically reduce mercury sources by employing alternative energy sources, restricting mercury trade and banning various mercury containing consumer products, such as dental amalgam are as essential as cleaning up the historical deposits of mercury in the basin. A strong political will and mass momentum are crucial for efficient mercury management. International cooperation is equally important. In the present paper, we have analyzed existing policies in respective jurisdictions to reduce mercury concentration in the Great Lakes environment. A brief review of the sources, occurrence in the Great Lakes, and the health effects of mercury is also included.

  17. Great big boulders I have known (United States)

    Beaty, Chester B.


    Large boulders on alluvial fans are widely dispersed in the American Basin and Range province. The sizes of the more massive blocks have long intrigued regional geomorphologists, who have been hard pressed to account for their origin and presence on the fans. Herein I describe and illustrate several such boulders along the western side of the White Mountains, California, and offer an explanation for their areal distribution and method of transport. A novel approach to determination of earthquake frequency is also discussed, one based upon the proposition that megalith-like blocks and clusters of boulders on a fan represent, indirectly, the effects of energetic seismic events in or near the parent mountain range.

  18. A new approach for monitoring ebolavirus in wild great apes.

    Directory of Open Access Journals (Sweden)

    Patricia E Reed


    Full Text Available Central Africa is a "hotspot" for emerging infectious diseases (EIDs of global and local importance, and a current outbreak of ebolavirus is affecting multiple countries simultaneously. Ebolavirus is suspected to have caused recent declines in resident great apes. While ebolavirus vaccines have been proposed as an intervention to protect apes, their effectiveness would be improved if we could diagnostically confirm Ebola virus disease (EVD as the cause of die-offs, establish ebolavirus geographical distribution, identify immunologically naïve populations, and determine whether apes survive virus exposure.Here we report the first successful noninvasive detection of antibodies against Ebola virus (EBOV from wild ape feces. Using this method, we have been able to identify gorillas with antibodies to EBOV with an overall prevalence rate reaching 10% on average, demonstrating that EBOV exposure or infection is not uniformly lethal in this species. Furthermore, evidence of antibodies was identified in gorillas thought previously to be unexposed to EBOV (protected from exposure by rivers as topological barriers of transmission.Our new approach will contribute to a strategy to protect apes from future EBOV infections by early detection of increased incidence of exposure, by identifying immunologically naïve at-risk populations as potential targets for vaccination, and by providing a means to track vaccine efficacy if such intervention is deemed appropriate. Finally, since human EVD is linked to contact with infected wildlife carcasses, efforts aimed at identifying great ape outbreaks could have a profound impact on public health in local communities, where EBOV causes case-fatality rates of up to 88%.

  19. Using stable isotopes to understand hydrochemical processes in and around a Prairie Pothole wetland in the Northern Great Plains, USA (United States)

    Mills, Christopher T.; Goldhaber, Martin B.; Stricker, Craig A.; Holloway, JoAnn M.; Morrison, Jean M.; Ellefsen, Karl J.; Rosenberry, Donald O.; Thurston, Roland S.


    Millions of internally drained wetland systems in the Prairie Potholes region of the northern Great Plains (USA and Canada) provide indispensable habitat for waterfowl and a host of other ecosystem services. The hydrochemistry of these systems is complex and a crucial control on wetland function, flora and fauna. Wetland waters can have high concentrations of SO2-4 due to the oxidation of large amounts of pyrite in glacial till that is in part derived from the Pierre shale. Water chemistry including δ18OH2O, δ2HH2O, and δ34SSO4 values, was determined for groundwater, soil pore water, and wetland surface water in and around a discharge wetland in North Dakota. The isotopic data for the first time trace the interaction of processes that affect wetland chemistry, including open water evaporation, plant transpiration, and microbial SO4 reduction.

    When considered from today’s vantage point, attempts to create cohesive nationstates through forced migration and/or assimilation of peoples come across as sources of insecurity for all those affected (Krishna 1999). However, in the late nineteenth and early twentieth centuries, both forced...... migration and assimilation were adopted as conflict-regulation measures. The assumption was that ‘cohesive’ nation-states would be less conflict-prone than others (see Joenniemi Chapter 7). Authors of the Lausanne Treaty (1923) between Turkey and the European great powers adopted such an understanding...... of conflict regulation when they agreed on exchanging population between Greece and Turkey. In the following years Turkey’s Republican leaders engaged in various spatial, economic and cultural practices in the attempt to create a ‘cohesive’ body politic.

  1. The great downside dilemma for risky emerging technologies

    International Nuclear Information System (INIS)

    Baum, Seth D


    Some emerging technologies promise to significantly improve the human condition, but come with a risk of failure so catastrophic that human civilization may not survive. This article discusses the great downside dilemma posed by the decision of whether or not to use these technologies. The dilemma is: use the technology, and risk the downside of catastrophic failure, or do not use the technology, and suffer through life without it. Historical precedents include the first nuclear weapon test and messaging to extraterrestrial intelligence. Contemporary examples include stratospheric geoengineering, a technology under development in response to global warming, and artificial general intelligence, a technology that could even take over the world. How the dilemma should be resolved depends on the details of each technology’s downside risk and on what the human condition would otherwise be. Meanwhile, other technologies do not pose this dilemma, including sustainable design technologies, nuclear fusion power, and space colonization. Decisions on all of these technologies should be made with the long-term interests of human civilization in mind. This paper is part of a series of papers based on presentations at the Emerging Technologies and the Future of Humanity event held at the Royal Swedish Academy of Sciences on 17 March 2014.

  3. Lessons learned from a great master!

    Directory of Open Access Journals (Sweden)

    Wagner Seixas da Silva


    critical thinking as early as the their first semester was something revolutionary and very attractive. This teaching strategy was so well accepted that was common to find either students who had already approved the course of Biochemistry or students attending advanced semesters returning to attend the class and to see the beloved teacher once again! In class it was possible to both discuss biochemistry and learn history! To have the classroom invaded by "actors" playing the judgment and beheading of Antoine-Laurent Lavoisier over 100 years after his death while discussing his experiments caused a whirlwind of emotions in the students. This was important to sensitize them to the challenges experienced by renowned scientists who paid with their lives to defend their ideas. Thus, students became protagonists of story and the biochemistry classes more interesting and challenging. This challenge was shared by the "actors", who actually were students of the Biological Chemistry program sharing the classroom with the great master. For these graduate students, it was an experience where they raised awareness of the importance of dedication to the teaching of Sciences.Prof. de Meis’ speech where he stated no one owns the truth or all knowledge was another point closing the relationship with the undergraduate students. In the modern world it is nearly impossible to keep yourself up to date, so we ended up specializing in something. De Meis used to cause some perplexity among the students by showing a picture with all copies of a single reputable scientific journal in the biochemistry field published over a year. Surprisingly, this stack of magazines was 1.5 meters tall! Could you imagine that all recent knowledge in biochemistry is compiled in few pages of a textbook? de Meis, then, revealed that we do not know everything, but we do need to learn how to interpret new facts, a new experiment, a new concept, a new technique, a new discovery. We need to develop critical thinking to

  4. [Prevention of dementia (including Alzheimer's disease)]. (United States)

    Kornhuber, H H


    Prevention of dementia: Life expectancy still increases linearly, and the elderly part of the European population grows rapidly in relation to the young. Dementia, however, grows even more rapidly, because it increases exponentially after age 65; it will become a great burden if nothing is done. The discussion so far is concentrated on treatment, whereas prevention is neglected. The therapy of dementia, however, has limited effect. Contrary to a widespread opinion prevention is possible. Genetic factors alone dominate the fate of cognition only in about 3 % of the cases. Besides age, lifestyle and the vascular risk factors exercise a great influence. High blood pressure carries a fourfold risk, diabetes more than doubles the risk both of the vascular and of the Alzheimer type; combined even more. Especially cerebral microangiopathy is strongly associated with Alzheimer's dementia, it triggers the vicious circle which leads to amyloid deposition. The importance of the circulation is underestimated, because most of the microvascular cerebral lesions are not perceived by the patient. All the risk factors for Alzheimer's disease after age 65 are also vascular risk factors especially for microangiopathy: Apo-E4, oestrogen deficiency, insulin resistance, diabetes, arterial hypertension, high cholesterol, old age and increased plasma homocystin which is often caused by alcohol consumption even in moderate doses. A healthy life style with daily outdoor activity and a Mediterranean diet not only reduces the risk of dementia, but also of coronary death and cancer. Cognitively stimulating activity protects even more than physical activity against dementia; the basis for this is acquired in youth by education. Therapy with statins is advisable if atherosclerosis cannot be reasonably counteracted by physical activity and diet.

  10. The great advances in radiation measurements

    International Nuclear Information System (INIS)

    Brodsky, A.


    The title of this banquet talk was selected to entertain conferees with recollections of major advances in dosimetry that have stimulated appetites for scientific progress. Recalling over fifty years of use of dosimetric instruments and concepts in the 1950-2000 era leads to an appreciation of many advances in solid state dosimetry, which others here know well and pursue vigorously. This author has been mainly a user, admirer, and interpreter of the fundamental methods of dose measurement. These advances have allowed ease of application in radiation protection and medical physics, for determining current routine and accidental exposures to workers, and for precise radiotherapeutic dose delivery. In more recent years, advances in identifying means of locating selective depositions of energy in various materials are providing ways of retrospectively assessing doses to tissue that were deposited many years ago. These methods also will allow development of quantitative theories of radiation damage once the lesions of interest are identified through further advances in molecular genetics. Yet, reflections on the past fifty years lead to increasing appreciation of the enormous achievements of our predecessors in the 1900-1950 period. Therefore, this presentation emphasises methods used by the author and some of his data interpretations during his 52-year career, with some examination of the earlier origin of some of these methods.

  11. Plutonium in autopsy tissues in Great Britain

    International Nuclear Information System (INIS)

    Popplewell, D.S.; Ham, G.J.; Johnson, T.E.; Barry, S.F.


    From time to time the authors have measured the Pu content of tissues taken at autopsy from people who had worked in the Pu-processing industries including some from Sellafield Works in Cumbria. During the work it became apparent that the results would be more enlightening if they could be compared with the levels of Pu in people who had not worked in the nuclear energy industries. With the objective of making this comparison, the authors commenced a series of Pu analyses on tissues removed at autopsy from members of the general public, who might be expected to have received their body deposits of Pu from fallout from atmospheric nuclear weapons explosions. This note augments some results reported previously in summary form

  12. Road safety campaign is a great success

    CERN Multimedia


    Rolf Heuer, the next Director-General of CERN, and Sigurd Lettow, the Director of Finance and Human Resources (photo below), completed all the tests of the CERN road safety campaign under the supervision of TCS instructors. The road safety campaign, which took place in the Main Building during the week of 10 November, attracted large numbers of participants. More than 300 CERN personnel and users took part in, and in some cases were literally bowled over by, the activities set up by instructors from the TCS (Touring Club Suisse). The campaign’s aim was to raise driver awareness of several aspects of road safety, including speed, use of mobile phones at the wheel, pedestrian priority, unlawful parking and driving with a valid licence. The campaign was an unqualified success! Even CERN’s directors joined in, testing their own reactions as drivers on the various pieces of apparatus in place.

  13. [Genetically modified food--great unknown]. (United States)

    Cichosz, G; Wiackowski, S K


    Genetically modified food (GMF) creates evident threat to consumers' health. In spite of assurances of biotechnologists, DNA of transgenic plants is instable, so, synthesis of foreign, allergenic proteins is possible. Due to high trypsin inhibitor content the GMF is digested much more slowly what, alike Bt toxin presence, increases probability of alimentary canal diseases. Next threats are bound to the presence of fitoestrogens and residues of Roundup pesticide, that can diminish reproductiveness; and even lead to cancerogenic transformation through disturbance of human hormonal metabolism. In spite of food producers and distributors assurances that food made of GMF raw materials is marked, de facto consumers have no choice. Moreover, along the food law products containing less than 0.9% of GMF protein are not included into genetically modified food.

  14. Liquefaction macrophenomena in the great Wenchuan earthquake (United States)

    Chen, Longwei; Yuan, Xiaoming; Cao, Zhenzhong; Hou, Longqing; Sun, Rui; Dong, Lin; Wang, Weiming; Meng, Fanchao; Chen, Hongjuan


    On May 12, 2008 at 14:28, a catastrophic magnitude M s 8.0 earthquake struck the Sichuan Province of China. The epicenter was located at Wenchuan (31.00°N, 103.40°E). Liquefaction macrophenomena and corresponding destruction was observed throughout a vast area of 500 km long and 200 km wide following the earthquake. This paper illustrates the geographic distribution of the liquefaction and the relationship between liquefaction behavior and seismic intensity, and summarizes the liquefaction macrophenomena, including sandboils and waterspouts, ground subsidence, ground fissures etc., and relevant liquefaction features. A brief summary of the structural damage caused by liquefaction is presented and discussed. Based on comparisons with liquefaction phenomena observed in the 1976 Tangshan and 1975 Haicheng earthquakes, preliminary analyses were performed, which revealed some new features of liquefaction behavior and associated issues arising from this event. The site investigation indicated that the spatial non-uniformity of liquefaction distribution was obvious and most of the liquefied sites were located in regions of seismic intensity VIII. However, liquefaction phenomena at ten different sites in regions of seismic intensity VI were also observed for the first time in China mainland. Sandboils and waterspouts ranged from centimeters to tens of meters, with most between 1 m to 3 m. Dramatically high water/sand ejections, e.g., more than 10 m, were observed at four different sites. The sand ejections included silty sand, fine sand, medium sand, course sand and gravel, but the ejected sand amount was less than that in the 1976 Tangshan earthquake. Possible liquefaction of natural gravel soils was observed for the first time in China mainland.

    International Nuclear Information System (INIS)

    Feldman, M.


    This presentation outlined commercial gas transmission activities along TransCanada Pipelines' wholly owned regulated pipelines in western Canada, including the Alberta System and the British Columbia (BC) System. TransCanada Pipelines owns and operates 41,000 km of pipeline that transport 11.5 billion cubic feet of gas per day. TransCanada's efforts to improve Alberta System economics were described along with the services it has developed to better connect supply and improve market access. This presentation included several illustrations depicting North American gas supply and demand; frontier resources in the Western Canada Sedimentary Basin (WCSB); pipelines that accommodate northern gas; Alberta gas demand; and, Pacific gas demand; The integration of the Gas Transmission Northwest (GTN) System in the energy grid of western North America was also discussed. It was determined that production from the WCSB remains stable and supply from BC will remain a key growth area for the WCSB. In addition, enhancements to the Alberta Hub, facilitated by TransCanada's Nova Inventory Transfer, will provides a great market for BC gas. figs

  16. A carbon balance model for the great dismal swamp ecosystem

    Directory of Open Access Journals (Sweden)

    Rachel Sleeter


    Full Text Available Abstract Background Carbon storage potential has become an important consideration for land management and planning in the United States. The ability to assess ecosystem carbon balance can help land managers understand the benefits and tradeoffs between different management strategies. This paper demonstrates an application of the Land Use and Carbon Scenario Simulator (LUCAS model developed for local-scale land management at the Great Dismal Swamp National Wildlife Refuge. We estimate the net ecosystem carbon balance by considering past ecosystem disturbances resulting from storm damage, fire, and land management actions including hydrologic inundation, vegetation clearing, and replanting. Results We modeled the annual ecosystem carbon stock and flow rates for the 30-year historic time period of 1985–2015, using age-structured forest growth curves and known data for disturbance events and management activities. The 30-year total net ecosystem production was estimated to be a net sink of 0.97 Tg C. When a hurricane and six historic fire events were considered in the simulation, the Great Dismal Swamp became a net source of 0.89 Tg C. The cumulative above and below-ground carbon loss estimated from the South One and Lateral West fire events totaled 1.70 Tg C, while management activities removed an additional 0.01 Tg C. The carbon loss in below-ground biomass alone totaled 1.38 Tg C, with the balance (0.31 Tg C coming from above-ground biomass and detritus. Conclusions Natural disturbances substantially impact net ecosystem carbon balance in the Great Dismal Swamp. Through alternative management actions such as re-wetting, below-ground biomass loss may have been avoided, resulting in the added carbon storage capacity of 1.38 Tg. Based on two model assumptions used to simulate the peat system, (a burn scar totaling 70 cm in depth, and the soil carbon accumulation rate of 0.36 t C/ha−1/year−1 for Atlantic white cedar, the total

  17. Was the death of Alexander the Great due to poisoning? Was it Veratrum album? (United States)

    Schep, Leo J; Slaughter, Robin J; Vale, J Allister; Wheatley, Pat


    To investigate the death of Alexander the Great to determine if he died from natural causes or was poisoned and, if the latter, what was the most likely poison. OVID MEDLINE (January 1950-May 2013) and ISI Web of Science (1900-May 2013) databases were searched and bibliographies of identified articles were screened for additional relevant studies. These searches identified 53 relevant citations. Classical literature associated with Alexander's death. There are two divergent accounts of Alexander's death. The first has its origins in the Royal Diary, allegedly kept in Alexander's court. The second account survives in various versions of the Alexander Romance. Nature of the terminal illness. The Royal Diary describes a gradual onset of fever, with a progressive inability to walk, leading to Alexander's death, without offering a cause of his demise. In contrast, the Romance implies that members of Alexander's inner circle conspired to poison him. The various medical hypotheses include cumulative debilitation from his previous wounds, the complications of alcohol imbibing (resulting in alcohol hepatitis, acute pancreatitis, or perforated peptic ulcer), grief, a congenital abnormality, and an unhealthy environment in Babylon possibly exacerbated by malaria, typhoid fever, or some other parasitic or viral illness. Was it poisoning? Of all the chemical and botanical poisons reviewed, we believe the alkaloids present in the various Veratrum species, notably Veratrum album, were capable of killing Alexander with comparable symptoms to those Alexander reportedly experienced over the 12 days of his illness. Veratrum poisoning is heralded by the sudden onset of epigastric and substernal pain, which may also be accompanied by nausea and vomiting, followed by bradycardia and hypotension with severe muscular weakness. Alexander suffered similar features for the duration of his illness. If Alexander the Great was poisoned, Veratrum album offers a more plausible cause than arsenic

  2. Intrusive upwelling in the Central Great Barrier Reef (United States)

    Benthuysen, Jessica A.; Tonin, Hemerson; Brinkman, Richard; Herzfeld, Michael; Steinberg, Craig


    In the Central Great Barrier Reef, the outer continental shelf has an open reef matrix that facilitates the exchange of waters with the Coral Sea. During austral summer, cool water intrudes onto the shelf along the seafloor. Temperature observations reveal cool, bottom intrusions during a 6 year period from the Queensland Integrated Marine Observing System's Palm Passage mooring. A metric is used to identify 64 intrusion events. These intrusions predominantly occur from October to March including the wet season. During an event, the outer-shelf's near-bottom temperature decreases by 1-3°C typically over 1 week. The near-bottom salinity tends to increase, while near-surface changes do not reflect these tendencies. Intrusion events occur predominantly with either weakening equatorward winds or poleward wind bursts. A regional hydrodynamic model for the Great Barrier Reef captures the timing and amplitude of these intrusions. During intrusion events, isotherms tend to uplift over the continental slope and onto the shelf and the East Australian Current intensifies poleward. Over the shelf, a bottom-intensified onshore current coincides with bottom cooling. For numerous events, the model diagnostics reveal that the cross-shelf flow is dominated by the geostrophic contribution. A vertical circulation tilts the isopycnals upward on the southern side of the passage, causing an along-shelf density gradient and geostrophic onshore flow with depth. While wind fluctuations play a major role in controlling the along-shelf currents, model results indicate that a concurrent topographically induced circulation can assist the onshore spread of cool water.

    Full Text Available In the context of a new concept of 'competence' as the main criterion and standard for graduates to meet requirements of labor market the article analyses the education system approaches to assessment and development of students’ skills, abilities and motivation since the reign of Emperor Nicholas I. It notes that in XIX-XX centuries there was a dominance of the level of standards relevant to real attainments of graduates while at the turn of the Millennium there was a significantly formalized approach. In all periods of history the real accomplishments of engineering brain and tremendous work, rather than the competences assessed the activities and professional qualities of the best representatives of the leading Russian engineering school, i.e. BMSTU, and this predetermined the continuity and motivation of the University generations. The article considers the origin of the term "competence", the evolution of its grading, and use in the educational and administrative practice. For example, the author's school of BMSTU "Professional English in the business world» (PEBW BMSTU, being equally successful before and after introduction of the new formal criterion, has shown indifference of innovation with regard to the results of professional education among the most advanced students. Because the results are determined by quality of teaching methods, the interdisciplinary approach, the teacher’s attainment level and student’s motivation, and it is impossible to single out the numerous elements of competence clusters in a complex and largely individual set of the higher school products, i.e. graduate’s skills.The article shows achievements of the most talented modern students and considers the most relevant problems such as a status quo in quality of modern education from their point of view. The modern competence-based approach is in tune with Regulation of the Nicholas General Staff Academy "for the ongoing identification and assessment of

    The "Great Recession" lasted from December 2007 to June 2009, and it wreaked havoc on the revenues of state (and local) governments. While the U.S. economy has improved since the end of the Great Recession, state government revenues have in most cases still not completely recovered. We use various indicators to measure how different states have -- or have not -- recovered in the aftermath of the Great Recession, and we also attempt to explain why these different patterns of recovery have emer...

    Bouyioukos, Costas; Bucchini, François; Elati, Mohamed; Képès, François


    GREAT (Genome REgulatory Architecture Tools) is a novel web portal for tools designed to generate user-friendly and biologically useful analysis of genome architecture and regulation. The online tools of GREAT are freely accessible and compatible with essentially any operating system which runs a modern browser. GREAT is based on the analysis of genome layout -defined as the respective positioning of co-functional genes- and its relation with chromosome architecture and gene expression. GREAT tools allow users to systematically detect regular patterns along co-functional genomic features in an automatic way consisting of three individual steps and respective interactive visualizations. In addition to the complete analysis of regularities, GREAT tools enable the use of periodicity and position information for improving the prediction of transcription factor binding sites using a multi-view machine learning approach. The outcome of this integrative approach features a multivariate analysis of the interplay between the location of a gene and its regulatory sequence. GREAT results are plotted in web interactive graphs and are available for download either as individual plots, self-contained interactive pages or as machine readable tables for downstream analysis. The GREAT portal can be reached at the following URL and each individual GREAT tool is available for downloading. © The Author(s) 2016.

  11. Full-wave calculation of fast-wave current drive in tokamaks including kparallel upshifts

    International Nuclear Information System (INIS)

    Jaeger, E.F.; Batchelor, D.B.


    Numerical calculations of fast-wave current drive (FWCD) efficiency have generally been of two types: ray tracing or global wave calculations. Ray tracing shows that the projection of the wave number (k parallel) along the magnetic field can vary greatly over a ray trajectory, particularly when the launch point is above or below the equatorial plane. As the wave penetrates toward the center of the plasma, k parallel increases, causing a decrease in the parallel phase speed and a corresponding decrease in the current drive efficiency, γ. But the assumptions of geometrical optics, namely short wavelength and strong single-pass absorption, are not greatly applicable in FWCD scenarios. Eigenmode structure, which is ignored in ray tracing, can play an important role in determining electric field strength and Landau damping rates. In such cases, a full-wave or global solution for the wave fields is desirable. In full-wave calculations such as ORION k parallel appear as a differential operator (rvec B·∇) in the argument of the plasma dispersion function. Since this leads to a differential system of infinite order, such codes of necessity assume k parallel ∼ k var-phi = const, where k var-phi is the toroidal wave number. Thus, it is not possible to correctly include effects of the poloidal magnetic field on k parallel. The problem can be alleviated by expressing the electric field as a superposition of poloidal modes, in which case k parallel is purely algebraic. This paper describes a new full-wave calculation, Poloidal Ion Cyclotron Expansion Solution, which uses poloidal and toroidal mode expansions to solve the wave equation in general flux coordinates. The calculation includes a full solution for E parallel and uses a reduced-order form of the plasma conductivity tensor to eliminate numerical problems associated with resolution of the very short wavelength ion Bernstein wave

  12. The impact of the Great Recession on untreated dental caries among kindergarten students in North Carolina. (United States)

    Abasaeed, Rania; Kranz, Ashley M; Rozier, R Gary


    The authors conducted a study to determine the impact of the Great Recession on untreated dental caries in kindergarten-aged children in North Carolina (NC). During the seven school years from 2003-2004 through 2009-2010, the state dental public health program assessed 608,339 kindergarten students for untreated decayed primary teeth (dt) as part of the statewide public health surveillance system. The authors aggregated observations to the school level and matched 7,660 school-year observations for 1,215 schools to National School Lunch Program (NSLP) participation rates, their primary economic indicator of the Great Recession. The authors included additional county-level economic indicators and measures of dentist supply and Medicaid enrollment. They used ordinary least squares regression with school-and year-fixed effects to examine the association of variables with the proportion of children with more than one dt for all schools and for schools with a greater than 10 percent increase in NSLP participation after 2006. The authors found a small but statistically significant association between the proportion of children in the schools participating in the NSLP and the proportion of kindergarten students who had more than one dt (β, 0.031; 95 percent confidence interval [CI], 0.001 to 0.0604). This association was greater in schools that had a greater than 10 percent increase in NSLP participation (β, 0.068; 95 percent CI, -0.007 to 0.143). Regression estimates indicate a 1.3- and 3.1-percentage point cumulative increase in the proportion of children with more than one dt during the period from 2008 through 2009 for all schools and high-risk schools, respectively. Increased NSLP enrollment was associated with less treatment for dental caries in 5-year-old children. Fewer children are receiving needed dental treatment because of the Great Recession. Recent gains made in the treatment of dental caries in children in NC have slowed as a result.

  13. Physical Monitoring of Flow Into and Within Great Salt Lake, Utah (United States)

    Kenney, T. A.; Naftz, D. L.; Perschon, W. C.


    Great Salt Lake (GSL) is the hydrologic terminus for the eastern part of the Great Basin. As the largest inland waterbody in the Western United States, GSL plays a critical ecologic role for many migratory bird species. In terms of harvest quantity and quality, the brine shrimp (Artemia) fishery of GSL is among the strongest in the world. The characteristic of GSL as a hydrologic sink amplifies anthropogenic activities throughout the basin, most specifically activities that occur along its eastern and southern shores, the urban corridor of the Wasatch Front. In 1959 GSL was divided into north and south parts by a rock-fill railroad causeway. Since then, an extreme density gradient between the north and south part exists as a result of limited conveyance of water from the south part where more than 95 percent of the total freshwater input occurs (Loving, and others, 2000). To date, little is known about the loading and cycling of various chemical constituents associated with human activities including nutrients, selenium, and mercury. Hydroacoustic technology, specifically acoustic Doppler technology, is currently being used to obtain a better physical understanding of GSL. Since 1999, stratified bi-directional discharge has been measured at the causeway breach with an acoustic Doppler current profiler. From these measurements, net flow components to the north and south have been used to assess the movement of water and salt through the causeway. Low hydraulic gradients and variable backwater conditions at the two largest inflows to GSL required the deployment of in-situ acoustic Doppler velocity meters to accurately compute continuous discharge, critical for constituent loading analyses. These discharge records, computed using the index velocity method, show sensitivity to large wind events that can lead to a complete reversal of flow. Velocity profiles acquired during two multi-day water-quality synoptic sampling runs with acoustic Doppler current profilers have

  17. The energy programme in Great Britain and Northern Ireland

    International Nuclear Information System (INIS)

    Fells, I.


    Great Britain and Northern Ireland are for the time being, thanks to North Sea oil and gas, self-supporting in energy supply (coal 36%, oil 34%, gas 23%, nuclear 6%, hydraulic 1%) a situation which may continue for 2 or 3 decades. By AD2101 it is expected that nuclear generation, including the use of fast-breeder reactors, will supply 50% of electrical energy (currently 14%). The article discusses primary energy sources with tabulated statistics from Government information, and mentions the 2000MW link with France now under construction. Among alternative resources the more promising appear to be wind generation and a Severn barrage; the latter could provide 2000-4000MW. Water power has very small potential but pumped storage (Dinorwic 1700MW) is important. The prospects for wave energy are poor. Acid rain is seen as a growing problem. Various ideas for energy saving are discussed and the present policy of examining the future of energy consumption in terms of 'scenarios' is briefly described. All of these include an increase in the proportion of electrical energy in the total consumption. (C.J.O.G.)

  18. Nereididae (Annelida: Phyllodocida) of Lizard Island, Great Barrier Reef, Australia. (United States)

    Glasby, Christopher J


    Nereididae is one of the most ubiquitous of polychaete families, yet knowledge of their diversity in the northern Great Barrier Reef is poor; few species have been previously reported from any of the atolls or islands including Lizard Island. In this study, the diversity of the family from Lizard Island and surrounding reefs is documented based on museum collections derived from surveys conducted mostly over the last seven years. The Lizard Island nereidid fauna was found to be represented by 14 genera and 38 species/species groups, including 11 putative new species. Twelve species are newly reported from Lizard Island; four of these are also first records for Australia. For each genus and species, diagnoses and/or taxonomic remarks are provided in addition to notes on their habitat on Lizard Island, and general distribution; the existence of tissue samples tied to vouchered museum specimens is indicated. Fluorescence photography is used to help distinguish closely similar species of Nereis and Platynereis. A key is provided to facilitate identification and encourage further taxonomic, molecular and ecological studies on the group.

  19. An Integrated Biochemistry Laboratory, Including Molecular Modeling (United States)

    Hall, Adele J. Wolfson Mona L.; Branham, Thomas R.


    The dilemma of designing an advanced undergraduate laboratory lies in the desire to teach and reinforce basic principles and techniques while at the same time exposing students to the excitement of research. We report here on a one-semester, project-based biochemistry laboratory that combines the best features of a cookbook approach (high success rate, achievement of defined goals) with those of an investigative, discovery-based approach (student involvement in the experimental design, excitement of real research). Individual modules may be selected and combined to meet the needs of different courses and different institutions. The central theme of this lab is protein purification and design. This laboratory accompanies the first semester of biochemistry (Structure and Function of Macromolecules, a course taken mainly by junior and senior chemistry and biological chemistry majors). The protein chosen as the object of study is the enzyme lysozyme, which is utilized in all projects. It is suitable for a student lab because it is easily and inexpensively obtained from egg white and is extremely stable, and its high isoelectric point (pI = 11) allows for efficient separation from other proteins by ion-exchange chromatography. Furthermore, a literature search conducted by the resourceful student reveals a wealth of information, since lysozyme has been the subject of numerous studies. It was the first enzyme whose structure was determined by crystallography (1). Hendrickson et al. (2) have previously described an intensive one-month laboratory course centered around lysozyme, although their emphasis is on protein stability rather than purification and engineering. Lysozyme continues to be the focus of much exciting new work on protein folding and dynamics, structure and activity (3 - 5). This lab course includes the following features: (i) reinforcement of basic techniques, such as preparation of buffers, simple enzyme kinetics, and absorption spectroscopy; (ii

    -processed meal. At the end of ten weeks only 60 per cent of the quail survived and the average live weight was only 138 grams.....When the level of dried whey was raised to 5 per cent to provide a margin of safety against abnormal feather growth (resulting partly from riboflavin deficiency), the number of survivals was nearly as high as on the diet containing 14 per cent sardine meal, but the average live weight per bird was only 139 grams. The difference between this weight and that for the birds on Diet 11 (3% dried whey) was not statistically significant.....The general rating for the diet was as high as that for Diet 11, when ground wheat replaced ground millet in the diet containing 3 per cent dried whey. Survival of birds was 5 per cent-units lower, the average live weight was about the same, and efficiency of feed utilization was higher.....Using D-activated animal sterol as a source of vitamin D and yellow corn and a good grade of alfalfa leaf meal as sources of vitamin A, fish oils were omitted from the diets without causing symptons of avitaminosis. However because of the instability of vitamin A in storage, it is advisable to include sufficient fish oil, if obtainable, in quail diets to supply at least 2,000 I. U. of vitamin A per pound of feed on a total feed basis.

  1. Great Lakes restoration success through science: U.S. Geological Survey accomplishments 2010 through 2013 (United States)



    The Great Lakes (Superior, Michigan, Huron, Erie, and Ontario) are the largest group of freshwater lakes on Earth and serve as an important source of drinking water, transportation, power, and recreational opportunities for the United States and Canada. They also support an abundant commercial and recreational fishery, are crucial for agriculture, and are essential to the economic vitality of the region. The Great Lakes support a wealth of biological diversity, including over 200 globally rare plants and animals and more than 40 species that are found nowhere else in the world. However, more than a century of environmental degradation has taken a substantial toll on the Great Lakes. To stimulate and promote the goal of a healthy Great Lakes region, President Obama and Congress created the Great Lakes Restoration Initiative (GLRI) in 2009. The GLRI is an interagency collaboration that seeks to address the most significant environmental problems in the Great Lakes ecosystem. The GLRI is composed of five focus areas that address these issues: Cleaning up toxic substances and Areas of Concern,

  2. Vertical distribution and fluxes of ammonia at Great Dun Fell (United States)

    Sutton, M. A.; Perthue, E.; Fowler, D.; Storeton-West, R. L.; Cape, J. N.; Arends, B. G.; Möls, J. J.

    As part of the study of the ammonia budget over Great Dun Fell, measurements of fluxes of gaseous ammonia (NH 3) with the hill surface (grass moorland and blanket bog) were made using micrometeorological techniques, to provide information on NH 3 removal by the hill surface and on vertical concentration gradients. Measurements of vertical concentration, χ, profiles of NH 3 concentration were coupled with turbulent diffusivities to determine fluxes, Fg deposition velocities, and canopy resistances, Rc to uptake by the ground. Consistent with published measurements for this site, NH 3 was generally found to deposit efficiently to the vegetation canopy, with mean Rc of 5 and 27 s m - for example days shown. However, short periods of NH 3 emission from the moorland were also observed at small χ (cloud processing: depletion of χ by in-cloud reaction would be expected to favour NH 3 emission from down-wind agricultural land and moorland, though emission from the hill itself during immersion in cloud is unlikely. Comparison of two measurement techniques to determine air concentrations (batch wet rotating denuder, inlet 0.5 m height; continuous wet denuder, inlets 0.3, 2 m heights) showed acceptable agreement, although because vertical concentration gradients were large (small Rc) the height of sampling had a substantial effect. Vertical gradients are also relevant to the use of the measured concentrations as estimates of NH 3 in the air mass passing over the hill, for modelling atmospheric budgets. Where NH 3 deposition occurs at the maximum rate, concentrations measured at 1 m require a 35% correction in neutral conditions when scaling to a reference height of 10 m.

  3. NASA's Great Observatories Celebrate the International Year of Astronomy (United States)


    [figure removed for brevity, see original site] Click on the image for larger version In 1609, Galileo improved the newly invented telescope, turned it toward the heavens, and revolutionized our view of the universe. In celebration of the 400th anniversary of this milestone, 2009 has been designated as the International Year of Astronomy. Today, NASA's Great Observatories are continuing Galileo's legacy with stunning images and breakthrough science from the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory. While Galileo observed the sky using visible light seen by the human eye, technology now allows us to observe in many wavelengths, including Spitzer's infrared view and Chandra's view in X-rays. Each wavelength region shows different aspects of celestial objects and often reveals new objects that could not otherwise be studied. This image of the spiral galaxy Messier 101 is a composite of views from Spitzer, Hubble, and Chandra. The red color shows Spitzer's view in infrared light. It highlights the heat emitted by dust lanes in the galaxy where stars can form. The yellow color is Hubble's view in visible light. Most of this light comes from stars, and they trace the same spiral structure as the dust lanes. The blue color shows Chandra's view in X-ray light. Sources of X-rays include million-degree gas, exploded stars, and material colliding around black holes. Such composite images allow astronomers to see how features seen in one wavelength match up with those seen in another wavelength. It's like seeing with a camera, night vision goggles, and X-ray vision all at once. In the four centuries since Galileo, astronomy has changed dramatically. Yet our curiosity and quest for knowledge remain the same. So, too, does our wonder at the splendor of the universe. The International Year of Astronomy Great Observatories Image Unveiling is supported by the NASA Science Mission Directorate Astrophysics Division. The project is a

  3. Air Bag Momentum Force Including Aspiration

    Directory of Open Access Journals (Sweden)

    Guy Nusholtz


    Full Text Available A gas-jet momentum force drives the air bag into position during a crash. The magnitude of this force can change as a result of aspiration. To determine the potential magnitude of the effect on the momentum force and mass flow rate in an aspirated system, a series of experiments and simulations of those experiments was conducted. The simulation consists of a two-dimensional unsteady isentropic CFD model with special “infinite boundaries”. One of the difficulties in simulating the gas-jet behavior is determining the mass flow rate. To improve the reliability of the mass flow rate input to the simulation, a sampling procedure involving multiple tests was used, and an average of the tests was adopted.

    Sieg, C.H. [Forest Service, Rapid City, SD (United States). Rocky Mountain Station; Meko, D.M.; Ni, W. [Univ. of Arizona, Tucson, AZ (United States). Lab. of Tree-Ring Research; DeGaetano, A.T.; Miller, J.R. Jr.; Bunkers, M.J. [South Dakota School of Mines and Technology, Rapid City, SD (United States)


    The purpose of this research is to increase the understanding of the magnitude, recurrence interval and periodicity of drought in the Northern Great Plains both from dendrochronological reconstructions and from analyses of available climate data. The objectives are to: (1) develop a network of climatically sensitive tree-ring chronologies to fill a void in the Northern Great Plains; (2) isolate climate variables most highly correlated with tree-growth; (3) reconstruct the drought history for the past 100 to 300 years; (4) identify regions which are climatically similar with respect to drought; (5) isolate patterns of drought persistence or recurrence; and (6) determine if drought recurrence is related to southern oscillation events. This paper summarizes progress on development of tree-ring chronologies in the Northern Great Plains preliminary analyses on the relationship between annual tree-ring widths and both precipitation and soil moisture and efforts to identify climatic regions and drought patterns in this region from climatic records.

  5. Fasting is not routinely required for determination of a lipid profile: clinical and laboratory implications including flagging at desirable concentration cut-points—a joint consensus statement from the European Atherosclerosis Society and European Federation of Clinical Chemistry and Laboratory Medicine (United States)

    Nordestgaard, Børge G.; Langsted, Anne; Mora, Samia; Kolovou, Genovefa; Baum, Hannsjörg; Bruckert, Eric; Watts, Gerald F.; Sypniewska, Grazyna; Wiklund, Olov; Borén, Jan; Chapman, M. John; Cobbaert, Christa; Descamps, Olivier S.; von Eckardstein, Arnold; Kamstrup, Pia R.; Pulkki, Kari; Kronenberg, Florian; Remaley, Alan T.; Rifai, Nader; Ros, Emilio; Langlois, Michel


    Abstract Aims To critically evaluate the clinical implications of the use of non-fasting rather than fasting lipid profiles and to provide guidance for the laboratory reporting of abnormal non-fasting or fasting lipid profiles. Methods and results Extensive observational data, in which random non-fasting lipid profiles have been compared with those determined under fasting conditions, indicate that the maximal mean changes at 1–6 h after habitual meals are not clinically significant [+0.3 mmol/L (26 mg/dL) for triglycerides; −0.2 mmol/L (8 mg/dL) for total cholesterol; −0.2 mmol/L (8 mg/dL) for LDL cholesterol; +0.2 mmol/L (8 mg/dL) for calculated remnant cholesterol; −0.2 mmol/L (8 mg/dL) for calculated non-HDL cholesterol]; concentrations of HDL cholesterol, apolipoprotein A1, apolipoprotein B, and lipoprotein(a) are not affected by fasting/non-fasting status. In addition, non-fasting and fasting concentrations vary similarly over time and are comparable in the prediction of cardiovascular disease. To improve patient compliance with lipid testing, we therefore recommend the routine use of non-fasting lipid profiles, while fasting sampling may be considered when non-fasting triglycerides >5 mmol/L (440 mg/dL). For non-fasting samples, laboratory reports should flag abnormal concentrations as triglycerides ≥2 mmol/L (175 mg/dL), total cholesterol ≥5 mmol/L (190 mg/dL), LDL cholesterol ≥3 mmol/L (115 mg/dL), calculated remnant cholesterol ≥0.9 mmol/L (35 mg/dL), calculated non-HDL cholesterol ≥3.9 mmol/L (150 mg/dL), HDL cholesterol ≤1 mmol/L (40 mg/dL), apolipoprotein A1 ≤1.25 g/L (125 mg/dL), apolipoprotein B ≥1.0 g/L (100 mg/dL), and lipoprotein(a) ≥50 mg/dL (80th percentile); for fasting samples, abnormal concentrations correspond to triglycerides ≥1.7 mmol/L (150 mg/dL). Life-threatening concentrations require separate referral when triglycerides >10 mmol/L (880 mg/dL) for the risk of pancreatitis, LDL cholesterol >13 mmol/L (500 mg

  9. Distinctiveness of prolonged grief disorder symptoms among survivors of the Great East Japan Earthquake and Tsunami. (United States)

    Tsutsui, Takumi; Hasegawa, Yukako; Hiraga, Masashi; Ishiki, Mikihito; Asukai, Nozomu


    Prolonged Grief Disorder (PGD) has been proposed for diagnostic classification as an independent psychiatric disorder. Previous research has investigated it in relation to other axis I disorders in order to determine whether it could be considered an independent nosological entity. The distinctiveness of this condition was apparent in cases of ordinary bereavement and in those following human-made disasters. However, this disorder may be expanded to include bereavement resulting from natural disasters. The present study aims to explore the differences between this disorder and posttraumatic stress disorder or major depressive disorder as experienced after the Great East Japan Earthquake and Tsunami. The subjects were 82 hospital workers. Each type of disorder was assessed by means of the Inventory of Complicated Grief, the Impact of Event Scale-Revised, and the Center for Epidemiological Studies Depression Scale. Exploratory factor analysis showed 3 dimensions, with PGD items independently clustering in the same dimension. Our findings support the uniqueness of PGD even in a post-natural disaster situation in a non-Western culture and warrant grief intervention for high-risk bereaved survivors.

  10. Report on maternal anxiety 16 months after the great East Japan earthquake disaster: anxiety over radioactivity. (United States)

    Yoshii, Hatsumi; Saito, Hidemitsu; Kikuchi, Saya; Ueno, Takashi; Sato, Kineko


    The Great East Japan Earthquake occurred on March 11, 2011. The tsunami caused extensive damage to the Fukushima Daiichi Nuclear Power Plant, resulting in a level 7 nuclear accident. Among those affected by this combined disaster were many pregnant and parturient women. Sixteen months after the earthquake, we conducted a questionnaire survey on anxiety among 259 women who gave birth around the time of the earthquake in Miyagi Prefecture, one of the affected areas. Participants reported 12 categories of anxiety, including anxiety over radioactivity. This study aimed to determine anxiety over radioactivity among this specific population and to record measures for future study. Anxiety over radiation was classified into seven subcategories: food safety, outdoor safety, effects on the fetuses of pregnant women, effects on children, radiation exposure, economic problems, and distrust of information disclosed. This study confirmed that concrete types of anxiety over radiation were keenly felt by mothers who had experienced the disaster who were currently raising children. The findings suggest the need to provide accurate information to these mothers, who are otherwise inundated with miscellaneous confusing information.

  11. Mid-Wisconsinan environments on the eastern Great Plains (United States)

    Baker, R.G.; Bettis, E. Arthur; Mandel, R.D.; Dorale, J.A.; Fredlund, G.G.


    Few sites on the eastern Great Plains contain paleobotanical records for the mid-Wisconsin. We report on four sites, two stream cutbanks and two quarry exposures, ranging in age from >50 to ???23.4 ka. The oldest site at >50 ka contains a suite of macrofossils from prairie and disturbed ground habitats, with no representation of trees, indicating an open prairie. By ???38 ka the assemblages include aquatic, wetland, mudflat, and prairie elements with rare specimens of Populus, Betula cf. papyrifera, Salix and at the most northerly site, Picea. This assemblage suggests a prairie/parkland with interspersed marshes, cooler temperatures and increased moisture. Populus and Salix continued to be represented from ???36 to ???29 ka, but the only other taxon was Carex. A hiatus may be present at some time during this interval. After ???29 ka, Picea became dominant on the uplands and it was joined by sedges in local wetlands. At sites near riverine loess sources, loess accumulation began to fill in the wetlands and organic deposition ceased some time after 29 ka. ?? 2009 Elsevier Ltd. All rights reserved.

  12. The Great Recession in Portugal: impact on hospital care use. (United States)

    Perelman, Julian; Felix, Sónia; Santana, Rui


    The Great Recession started in Portugal in 2009, coupled with severe austerity. This study examines its impact on hospital care utilization, interpreted as caused by demand-side effects (related to variations in population income and health) and supply-side effects (related to hospitals' tighter budgets and reduced capacity). The database included all in-patient stays at all Portuguese NHS hospitals over the 2001-2012 period (n=17.7 millions). We analyzed changes in discharge rates, casemix index, and length of stay (LOS), using a before-after methodology. We additionally measured the association of health care indicators to unemployment. A 3.2% higher rate of discharges was observed after 2009. Urgent stays increased by 2.5%, while elective in-patient stays decreased by 1.4% after 2011. The LOS was 2.8% shorter after the crisis onset, essentially driven by the 4.5% decrease among non-elective stays. A one percentage point increase in unemployment rate was associated to a 0.4% increase in total volume, a 2.3% decrease in day cases, and a 0.1% decrease in LOS. The increase in total and urgent cases may reflect delayed out-patient care and health deterioration; the reduced volume of elective stays possibly signal a reduced capacity; finally, the shorter stays may indicate either efficiency-enhancing measures or reduced quality.

  13. European health inequality through the 'Great Recession': Social policy matters. (United States)

    van der Wel, Kjetil A; Saltkjel, Therese; Chen, Wen-Hao; Dahl, Espen; Halvorsen, Knut


    This paper investigates the association between the Great Recession and educational inequalities in self-rated general health in 25 European countries. We investigate four different indicators related to economic recession: GDP; unemployment; austerity and a 'crisis' indicator signifying severe simultaneous drops in GDP and welfare generosity. We also assess the extent to which health inequality changes can be attributed to changes in the economic conditions and social capital in the European populations. The paper uses data from the European Social Survey (2002-2014). The analyses include both cross-sectional and lagged associations using multilevel linear regression models with country fixed effects. This approach allows us to identify health inequality changes net of all time-invariant differences between countries. GDP drops and increasing unemployment were associated with decreasing health inequalities. Austerity, however, was related to increasing health inequalities, an association that grew stronger with time. The strongest increase in health inequality was found for the more robust 'crisis' indicator. Changes in trust, social relationships and in the experience of economic hardship of the populations accounted for much of the increase in health inequality. The paper concludes that social policy has an important role in the development of health inequalities, particularly during times of economic crisis. © 2018 The Authors.

    Lessons learned from actions taken by DMAT (Disaster Medical Assistant Team) at the Great East Japan Disaster (Mar. 11) are reported. One unit of DMAT consists from 2 doctors, 2 nurses and 1 logistics clerk, who all had education and training authorized by Japan MHLW. On the disaster, MHLW and suffering prefectures can order DMAT to gather at the disaster base hospital or SCU (Staging Care Unit) like an airport nearby. DMAT missions are firstly to grasp the medical state of the disaster and its report to the MHLW through EMIS (Emergency Medical Information System), and then to estimate the possible numbers of serious patients, their transporting systems and further DMAT needed. Within 3 days after the Disaster, 32 base hospitals in Iwate, Miyagi and Fukushima prefectures received 2,092 patients including 752 serious ones. Needs for DMAT were rather scarce within 48 hr after the Disaster and 103 DMAT in total within Mar. 14 in the 3 prefectures decreased to 50 of 840 patients in the area of 20 km distance from the Plant died during urgent evacuation without medicare staff due to deterioration of the basal disease, dehydration, hypothermia, etc., suggesting necessity of the more flexible action of DMAT, of which responsibility has been defined to be essentially within 48 hr after the disaster. Probably, DMAT should have assumption that complicated disaster with natural and atomic courses can occur at the earthquake in future. (T.T.)

  15. A great start for the whole CERN accelerator chain

    CERN Multimedia


    With physics data-taking under way this week at the LHC, I’d like to take a look at what’s been happening at the rest of the CERN accelerator chain.   The LHC tends to dominate the news from CERN for all kinds of reasons, beech martens included, but we should not forget that there is a unique chain of accelerators upstream of the LHC, tended to and operated by an incredible group of people. If our whole accelerator chain does not work perfectly, nor can the LHC, and in addition to forming the LHC’s injector chain, our upstream accelerators support their own experiments, bringing great diversity to the CERN research programme. The chain begins with the proton source and Linac2, which have been faithfully delivering beams since 1978. This year, Linac2 accelerated its first beams on 29 February. Beams were then passed on to the PS Booster and the veteran PS, the linchpin of the CERN accelerator complex and in operation since 1959. The final link in the chain before the ...

  16. Benthic Foraminifera from the Capricorn Group, Great Barrier Reef, Australia. (United States)

    Mamo, Briony L


    Effective reef management and monitoring has become increasingly important as anthropogenic processes impact upon natural ecosystems. One locality that is under direct threat due to human activities is the Australian Great Barrier Reef (GBR). Marine foraminifera represent an abundant and readily applicable tool that can be used in reef studies to investigate a variety of ecological parameters and assist in understanding reef dynamics and influence management protocols. The first step is to establish a baseline knowledge of taxonomic composition within the region to facilitate comparative studies and monitor how assemblages change in order to maximise effective management. A detailed taxonomic assessment is provided of 133 species of benthic foraminifera in 76 genera from Heron Island, One Tree Island, Wistari and Sykes Reefs, which form the core of the Capricorn Group (CG) at the southern end of the GBR. Of these 133 species, 46% belong to the order Miliolida, 34% to Rotaliida, 7% to Textulariida, 5% to Lagenida, 3% to Lituolida, 3% to Spirillinida, 1% to Loftusiida and 1% to Robertinida. Samples were collected from a variety of shallow shelf reef environments including reef flat, lagoonal and channel environments. Seventy species, representing the most abundant forms, are formally described with detailed distribution data for the remaining 63 species supplied.

  13. Great and old earthquakes against great and old paradigms ─ paradoxes, historical roots, alternative answers

    G. Scalera


    Full Text Available The similarity of the vertical displacements shown by case-history extreme-magnitude earthquakes are scrutinised (Chile 1960, Alaska 1964, Sumatra 2004, .... A common interpretation – an uprising of lithospheric material – can be found, which is supported by the irregularities of the hypocentres distribution along the Wadati-Benioff zones. In the case of major South American earthquakes, a volcanic eruptions-earthquakes correlation is recognisable. Further support to this interpretation is the displacement of the Earth's instantaneous rotation pole – ≈3.0 mas (≈10 cm, observed at ASI of Matera, Italy – the seismic data (USGS in the two days following the main shock, the geomorphologic data, and the satellite data of uplift/subsidence of the coasts (IGG make possible a new interpretation of the Great Sumatran earthquake (26 December 2004 based on the second conjugate – nearly vertical – CMT fault plane solution. All this converges toward different causes of seismogenetic processes, strongly supporting a deep origin of disturbances, fluxes of materials leading to more or less sudden movements of masses, and phase changes, which lead to either earthquakes or silent-slow events in Wadati-Benioff zones. A reinterpretation of the geodynamics of the active margins and mountain building is proposed with a heuristic model that does not resort to large-scale subduction, but only to isostatic uplift of deep material intruding between two decoupling plates in a tensional environment. Concomitant phase changes toward less-packed lattice and buoyancy effect caused by the Clapeyron slope can help the extrusion of material over the m.s.l., constituting an orogenic process. The phenomena expected to occur in the model directly and harmoniously contribute to the building up of the surface geophysical and geomorphological features of the orogenic zones.

  14. Halogenated flame retardants in the Great Lakes environment. (United States)

    Venier, Marta; Salamova, Amina; Hites, Ronald A


    Flame retardants are widely used industrial chemicals that are added to polymers, such as polyurethane foam, to prevent them from rapidly burning if exposed to a small flame or a smoldering cigarette. Flame retardants, especially brominated flame retardants, are added to many polymeric products at percent levels and are present in most upholstered furniture and mattresses. Most of these chemicals are so-called "additive" flame retardants and are not chemically bound to the polymer; thus, they migrate from the polymeric materials into the environment and into people. As a result, some of these chemicals have become widespread pollutants, which is a concern given their possible adverse health effects. Perhaps because of their environmental ubiquity, the most heavily used group of brominated flame retardants, the polybrominated diphenyl ethers (PBDEs), was withdrawn from production and use during the 2004-2013 period. This led to an increasing demand for other flame retardants, including other brominated aromatics and organophosphate esters. Although little is known about the use or production volumes of these newer flame retardants, it is evident that some of these chemicals are also becoming pervasive in the environment and in humans. In this Account, we describe our research on the occurrence of halogenated and organophosphate flame retardants in the environment, with a specific focus on the Great Lakes region. This Account starts with a short introduction to the first generation of brominated flame retardants, the polybrominated biphenyls, and then presents our measurements of their replacement, the PBDEs. We summarize our data on PBDE levels in babies, bald eagles, and in air. Once these compounds came off the market, we began to measure several of the newer flame retardants in air collected on the shores of the Great Lakes once every 12 days. These new measurements focus on a tetrabrominated benzoate, a tetrabrominated phthalate, a hexabrominated diphenoxyethane

  15. Assessment of a new seasonal to inter-annual operational Great Lakes water supply, water levels, and connecting channel flow forecasting system (United States)

    Gronewold, A.; Fry, L. M.; Hunter, T.; Pei, L.; Smith, J.; Lucier, H.; Mueller, R.


    The U.S. Army Corps of Engineers (USACE) has recently operationalized a suite of ensemble forecasts of Net Basin Supply (NBS), water levels, and connecting channel flows that was developed through a collaboration among USACE, NOAA's Great Lakes Environmental Research Laboratory, Ontario Power Generation (OPG), New York Power Authority (NYPA), and the Niagara River Control Center (NRCC). These forecasts are meant to provide reliable projections of potential extremes in daily discharge in the Niagara and St. Lawrence Rivers over a long time horizon (5 years). The suite of forecasts includes eight configurations that vary by (a) NBS model configuration, (b) meteorological forcings, and (c) incorporation of seasonal climate projections through the use of weighting. Forecasts are updated on a weekly basis, and represent the first operational forecasts of Great Lakes water levels and flows that span daily to inter-annual horizons and employ realistic regulation logic and lake-to-lake routing. We will present results from a hindcast assessment conducted during the transition from research to operation, as well as early indications of success rates determined through operational verification of forecasts. Assessment will include an exploration of the relative skill of various forecast configurations at different time horizons and the potential for application to hydropower decision making and Great Lakes water management.

  16. Why greatness cannot be planned the myth of the objective

    CERN Document Server

    Stanley, Kenneth O


    Why does modern life revolve around objectives? From how science is funded, to improving how children are educated -- and nearly everything in-between -- our society has become obsessed with a seductive illusion: that greatness results from doggedly measuring improvement in the relentless pursuit of an ambitious goal. In Why Greatness Cannot Be Planned, Stanley and Lehman begin with a surprising scientific discovery in artificial intelligence that leads ultimately to the conclusion that the objective obsession has gone too far. They make the case that great achievement can't be bottled up int

  17. "Most brilliant in judgment": Alexander the Great and Aristotle. (United States)

    Lainas, Panagiotis; Panutsopulos, Dimitrios; Skandalakis, Panagiotis N; Zoras, Odysseas; Skandalakis, John E


    From historical sources, it is evident that Alexander the Great was indebted to one of his teachers, Aristotle of Stagira. It was the teaching of Aristotle that evoked all the nascent talents of young Alexander and turned him into a great man. Alexander was extremely interested in the secrets of medicine and considered it an art. The medical knowledge he acquired from Aristotle may have saved his life and the lives of his troops on many occasions. If Alexander did not possess medical knowledge and if his everyday life had not been so greatly influenced by medicine, he might never have been able to create his empire.

  18. ASEAN and Strategic Rivalry among the Great Powers in Asia

    Directory of Open Access Journals (Sweden)

    Fenna Egberink


    Full Text Available This paper looks at ASEAN’s role in the context of the three main bilateral relations among the great powers in Asia: China-US, China-Japan, and China-India. The authors argue that although ASEAN’s influence is limited in terms of geographical reach and its impact on actual security issues, Southeast Asia is potentially an important object of great power rivalry and thus the sub-region is highly relevant to Asian geopolitics. The key question with regard to geopolitical stability is how ASEAN will deal with increased great power rivalries in its own sub-region.

  19. Phreatophytic land-cover map of the northern and central Great Basin Ecoregion: California, Idaho, Nevada, Utah, Oregon, and Wyoming (United States)

    Mathie, Amy M.; Welborn, Toby L.; Susong, David D.; Tumbusch, Mary L.


    Increasing water use and changing climate in the Great Basin of the western United States are likely affecting the distribution of phreatophytic vegetation in the region. Phreatophytic plant communities that depend on groundwater are susceptible to natural and anthropogenic changes to hydrologic flow systems. The purpose of this report is to document the methods used to create the accompanying map that delineates areas of the Great Basin that have the greatest potential to support phreatophytic vegetation. Several data sets were used to develop the data displayed on the map, including Shrub Map (a land-cover data set derived from the Regional Gap Analysis Program) and Gap Analysis Program (GAP) data sets for California and Wyoming. In addition, the analysis used the surface landforms from the U.S. Geological Survey (USGS) Global Ecosystems Mapping Project data to delineate regions of the study area based on topographic relief that are most favorable to support phreatophytic vegetation. Using spatial analysis techniques in a GIS, phreatophytic vegetation classes identified within Shrub Map and GAP were selected and compared to the spatial distribution of selected landforms in the study area to delineate areas of phreatophyte vegetation. Results were compared to more detailed studies conducted in selected areas. A general qualitative description of the data and the limitations of the base data determined that these results provide a regional overview but are not intended for localized studies or as a substitute for detailed field analysis. The map is intended as a decision-support aide for land managers to better understand, anticipate, and respond to ecosystem changes in the Great Basin.

  20. Climate change projections for lake whitefish (Coregonus clupeaformis) recruitment in the 1836 Treaty Waters of the Upper Great Lakes (United States)

    Lynch, Abigail J.; Taylor, William W.; Beard, T. Douglas; Lofgren, Brent M.


    Lake whitefish (Coregonus clupeaformis) is an ecologically, culturally, and economically important species in the Laurentian Great Lakes. Lake whitefish have been a staple food source for thousands of years and, since 1980, have supported the most economically valuable (annual catch value ≈ US$16.6 million) and productive (annual harvest ≈ 7 million kg) commercial fishery in the upper Great Lakes (Lakes Huron, Michigan, and Superior). Climate changes, specifically changes in temperature, wind, and ice cover, are expected to impact the ecology, production dynamics, and value of this fishery because the success of recruitment to the fishery has been linked with these climatic variables. We used linear regression to determine the relationship between fall and spring air temperature indices, fall wind speed, winter ice cover, and lake whitefish recruitment in 13 management units located in the 1836 Treaty Waters of the Upper Great Lakes ceded by the Ottawa and Chippewa nations, a culturally and commercially important region for the lake whitefish fishery. In eight of the 13 management units evaluated, models including one or more climate variables (temperature, wind, ice cover) explained significantly more variation in recruitment than models with only the stock–recruitment relationship, using corrected Akaike's Information Criterion comparisons (ΔAICc > 3). Isolating the climate–recruitment relationship and projecting recruitment with the Coupled Hydrosphere-Atmosphere Research Model (CHARM) indicated the potential for increased lake whitefish recruitment in the majority of the 1836 Treaty Waters management units. These results can inform adaptive management strategies by providing anticipated implications of climate on lake whitefish recruitment.

  1. Photoactive devices including porphyrinoids with coordinating additives (United States)

    Forrest, Stephen R; Zimmerman, Jeramy; Yu, Eric K; Thompson, Mark E; Trinh, Cong; Whited, Matthew; Diev, Vlacheslav


    Coordinating additives are included in porphyrinoid-based materials to promote intermolecular organization and improve one or more photoelectric characteristics of the materials. The coordinating additives are selected from fullerene compounds and organic compounds having free electron pairs. Combinations of different coordinating additives can be used to tailor the characteristic properties of such porphyrinoid-based materials, including porphyrin oligomers. Bidentate ligands are one type of coordinating additive that can form coordination bonds with a central metal ion of two different porphyrinoid compounds to promote porphyrinoid alignment and/or pi-stacking. The coordinating additives can shift the absorption spectrum of a photoactive material toward higher wavelengths, increase the external quantum efficiency of the material, or both.

    We show how integrodifferential equations typical of jet calculus can be combined with an averaging procedure to obtain jet-calculus-based results including the Mueller interference graphs. Results in longitudinal-momentum fraction x for physical quantities are higher at intermediate x and lower at large x than with the conventional ''incoherent'' jet calculus. These results resemble those of Marchesini and Webber, who used a Monte Carlo approach based on the same dynamics

  6. The detection of great crested newts year round via environmental DNA analysis. (United States)

    Rees, Helen C; Baker, Claire A; Gardner, David S; Maddison, Ben C; Gough, Kevin C


    Analysis of environmental DNA (eDNA) is a method that has been used for the detection of various species within water bodies. The great crested newt (Triturus cristatus) has a short eDNA survey season (mid-April to June). Here we investigate whether this season could be extended into other months using the current methodology as stipulated by Natural England. Here we present data to show that in monthly water samples taken from two ponds (March 2014-February 2015) we were able to detect great crested newt DNA in all months in at least one of the ponds. Similar levels of great crested newt eDNA (i.e. highly positive identification) were detected through the months of March-August, suggesting it may be possible to extend the current survey window. In order to determine how applicable these observations are for ponds throughout the rest of the UK, further work in multiple other ponds over multiple seasons is suggested. Nevertheless, the current work clearly demonstrates, in two ponds, the efficacy and reproducibility of eDNA detection for determining the presence of great crested newts.

  7. Evaluating Hydrologic Transience in Watershed Delineation, Numerical Modeling and Solute Transport in the Great Basin. Clayton Valley, Nevada (United States)

    Underdown, C. G.; Boutt, D. F.; Hynek, S. A.; Munk, L. A.


    Importance of transience in managed groundwater systems is generally determined by timeframe of management decisions. Watersheds with management times shorter than the aquifer (watershed) response time, or the time it takes a watershed to recover from a change in hydrologic state, would not include the new state and are treated as steady-state. However, these watersheds will experience transient response between hydrologic states. Watershed response time is a function of length. Therefore flat, regional watersheds characteristic of the Great Basin have long response times. Defining watershed extents as the area in which the water budget is balanced means inputs equal outputs. Steady-state budgets in the Great Basin have been balanced by extending watershed boundaries to include more area for recharge; however, the length and age of requisite flow paths are poorly constrained and often unrealistic. Inclusion of stored water in hydrologic budget calculations permits water balance within smaller contributing areas. As groundwater flow path lengths, depths, and locations differ between steady-state and transient systems, so do solute transport mechanisms. To observe how transience affects response time and solute transport, a refined (transient) version of the USGS steady-state groundwater flow model of the Great Basin is evaluated. This model is used to assess transient changes in contributing area for Clayton Valley, a lithium-brine producing endorheic basin in southwestern Nevada. Model runs of various recharge, discharge and storage bounds are created from conceptual models based upon historical climate data. Comparing results of the refined model to USGS groundwater observations allows for model validation and comparison against the USGS steady-state model. The transient contributing area to Clayton Valley is 85% smaller than that calculated from the steady-state solution, however several long flow paths important to both water and solute budgets at Clayton Valley

  8. Revisiting Hansen Solubility Parameters by Including Thermodynamics. (United States)

    Louwerse, Manuel J; Maldonado, Ana; Rousseau, Simon; Moreau-Masselon, Chloe; Roux, Bernard; Rothenberg, Gadi


    The Hansen solubility parameter approach is revisited by implementing the thermodynamics of dissolution and mixing. Hansen's pragmatic approach has earned its spurs in predicting solvents for polymer solutions, but for molecular solutes improvements are needed. By going into the details of entropy and enthalpy, several corrections are suggested that make the methodology thermodynamically sound without losing its ease of use. The most important corrections include accounting for the solvent molecules' size, the destruction of the solid's crystal structure, and the specificity of hydrogen-bonding interactions, as well as opportunities to predict the solubility at extrapolated temperatures. Testing the original and the improved methods on a large industrial dataset including solvent blends, fit qualities improved from 0.89 to 0.97 and the percentage of correct predictions rose from 54 % to 78 %. Full Matlab scripts are included in the Supporting Information, allowing readers to implement these improvements on their own datasets. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

  13. The Great Kanto earthquake and F. Scott Fitzgerald (United States)

    Kawakatsu, Hitoshi; Bina, Craig R.

    How many recall the following striking sentence from The Great Gatsby by F. Scott Fitzgerald, which appears on the second page of the novel, where Fitzgerald first introduces Gatsby? “If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life, as if he were related to one of those intricate machines that register earthquakes ten thousand miles away.”This line may have failed to focus our attention when we first read the book in our younger days. Now, however, as a Japanese seismologist and an American geophysicist (and student of Japanese culture), we would be greatly remiss for failing to take greater note of this statement. Indeed, as The Great Gatsby was published in 1925, it occurred to us that the earthquake Fitzgerald might have been thinking of was the Great Kanto earthquake, which occurred on September 1, 1923 and devastated the Tokyo metropolitan area.

  16. The Great Lakes Fisheries Specimen Bank: a Canadian perspective in environmental specimen banking. (United States)

    Kiriluk, R M; Whittle, D M; Keir, M J; Carswell, A A; Huestis, S Y


    Since 1977 the Canadian Department of Fisheries and Oceans (DFO) has maintained a specimen bank for retrospective chemical analyses. The Great Lakes Fisheries Specimen Bank (GLFSB) is a complementary activity to the department's ongoing Great Lakes Contaminants Surveillance Program that has annually, since 1977, monitored levels of metals and organochlorines in aquatic biota throughout the Canadian Great Lakes. Past activities have focused on defining the effects of long-term frozen storage on the integrity of organochlorine residues in archived biological tissues. Archived samples have been reanalyzed for total PCBs, PCB congeners including co-planar PCBs, dioxin and furan isomers, and 22 toxaphene congeners. More recently, archived samples of predatory fish have been analyzed for stable isotopes of nitrogen (delta 15N) and carbon (delta 13C), as indicators of historical changes in food web dynamics. A catalogue or user-guide has recently been completed describing all information associated with samples stored in the GLFSB.

  19. A New Keynesian Perspective on the Great Recession


    Peter N. Ireland


    With an estimated New Keynesian model, this paper compares the "Great Recession" of 2007-09 to its two immediate predecessors in 1990-91 and 2001. The model attributes all three downturns to a similar mix of aggregate demand and supply disturbances. The most recent series of adverse shocks lasted longer and became more severe, however, prolonging and deepening the Great Recession. In addition, the zero lower bound on the nominal interest rate prevented monetary policy from stabilizing the US ...

  20. Unemployment of Non-western Immigrants in the Great Recession


    Cerveny, J.; Ours, J.C. van


    Abstract: This paper examines whether unemployment of non-western immigrant workers in the Netherlands was disproportionally affected by the Great Recession. We analyze unemployment data covering the period November 2007 to February 2013 finding that the Great Recession affected unemployment rates of non-western immigrant workers in absolute terms more than unemployment rates of native workers. However, in relative terms there is not much of a difference. We also find that the sensitivity of ...

  3. Determination of the Darcy permeability of porous media including sintered metal plugs (United States)

    Frederking, T. H. K.; Hepler, W. A.; Yuan, S. W. K.; Feng, W. F.


    Sintered-metal porous plugs with a normal size of the order of 1-10 microns are used to evaluate the Darcy permeability of laminar flow at very small velocities in laminar fluids. Porous media experiment results and data adduced from the literature are noted to support the Darcy law analog for normal fluid convection in the laminar regime. Low temperature results suggest the importance of collecting room temperature data prior to runs at liquid He(4) temperatures. The characteristic length diagram gives a useful picture of the tolerance range encountered with a particular class of porous media.

  7. Socio-cultural determinants of child mortality in southern Peru: including some methodological considerations. (United States)

    de Meer, K; Bergman, R; Kusner, J S


    Among Amerindian children living at high altitude in the Andes in southern Peru, high child mortality rates have been reported in the literature, especially in the perinatal and neonatal period. We compared mortality rates in children calculated from retrospective survey data in 86 rural families from 2 Aymara and 3 Quechua peasant communities living at the same level of altitude (3825 m) in southern Peru. Relations between land tenure, socio-cultural factors and child mortality were studied, and methodological considerations in this field of interest are discussed. Checks on consistency of empirical data showed evidence for underreporting of neonatal female deaths with birth order 3 and more. Perinatal (124 vs 34 per 1000 births) and infant mortality (223 vs 111 per 1000 live births) was significantly higher in Aymara compared with Quechua children, but no difference was found after the first year of life. A short pregnancy interval was associated with an elevated perinatal and infant mortality rate, and a similar albeit insignificant association was found with increased maternal age. Amount of land owned and birth order were not related with child mortality. Although levels of maternal education are generally low in both cultures, a consistent decline in infant and child mortality was found with the amount of years mothers had attended school. However, the results suggest a U-shaped relationship between the amount of years of parental education and perinatal mortality in offspring. Late fetal and early neonatal mortality were particularly high in one Aymara community where mothers were found to have more years of education. Infanticide, a known phenomenon in the highlands of the Andes, is discussed in relation with the findings of the study. Although maternal and child health services are utilized by the majority of families in 4 of 5 study communities, 43 of 51 mothers under the age of 45 years reported that they delivered their last baby in the absence of traditional midwives or official medical supervision.

  8. Renegotiation of the 1987 Great Lakes Water Quality Agreement: From Confusion to Promise

    Directory of Open Access Journals (Sweden)

    Gail Krantzberg


    Full Text Available For nearly four decades, the Great Lakes regime has invoked the Great Lakes Water Quality Agreement as the mechanism for binational cooperation on programs and policies. Many advances in water quality have led to unquestionable improvements in ecosystem quality, habitat and biodiversity, and water infrastructure. Still, Great Lakes scientists have issued compelling evidence that the ecological health of the basin ecosystem is at significant risk. In 2012, the Agreement will be revised for the first time in 25 years. The degree of engagement in a future Agreement, including scope, issues of significant importance, governance and collaboration will hinge on a thorough analytical process, so far seemingly absent, coupled with real consultation, so far marginally evident. Renegotiating the Agreement to generate a revitalized and sustainable future mandates that science inform contemporary public policy, and that inclusive discourse and public engagement be integral through the process. Many of these steps are still absent, and the analysis presented here strongly suggests that the constituents of the Great Lakes regime voice their views critically, emphatically, and often. If the negotiators listen, we can collectively make the Lakes Great.

  9. Dreissenid mussels from the Great Lakes contain elevated thiaminase activity (United States)

    Tillitt, D.E.; Riley, S.C.; Evans, A.N.; Nichols, S.J.; Zajicek, J.L.; Rinchard, J.; Richter, C.A.; Krueger, C.C.


    We examined thiaminase activity in dreissenid mussels collected at different depths and seasons, and from various locations in Lakes Michigan, Ontario, and Huron. Here we present evidence that two dreissenid mussel species (Dreissena bugensis and D. polymorpha) contain thiaminase activity that is 5-100 fold greater than observed in Great Lakes fishes. Thiaminase activity in zebra mussels ranged from 10,600 to 47,900??pmol g- 1??min- 1 and activities in quagga mussels ranged from 19,500 to 223,800??pmol g- 1??min- 1. Activity in the mussels was greatest in spring, less in summer, and least in fall. Additionally, we observed greater thiaminase activity in dreissenid mussels collected at shallow depths compared to mussels collected at deeper depths. Dreissenids constitute a significant and previously unknown pool of thiaminase in the Great Lakes food web compared to other known sources of this thiamine (vitamin B1)-degrading enzyme. Thiaminase in forage fish of the Great Lakes has been causally linked to thiamine deficiency in salmonines. We currently do not know whether linkages exist between thiaminase activities observed in dreissenids and the thiaminase activities in higher trophic levels of the Great Lakes food web. However, the extreme thiaminase activities observed in dreissenids from the Great Lakes may represent a serious unanticipated negative effect of these exotic species on Great Lakes ecosystems.

  10. Fibrodysplasia ossificans progressiva (FOP): watch the great toes! (United States)

    Kartal-Kaess, Mutlu; Shore, Eileen M; Xu, Meiqi; Schwering, Ludwig; Uhl, Markus; Korinthenberg, Rudolf; Niemeyer, Charlotte; Kaplan, Frederick S; Lauten, Melchior


    Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder and the most disabling condition of heterotopic (extraskeletal) ossification in humans. Extraskeletal bone formation associated with inflammation preceding the osseous conversion usually begins in the first decade, predominantly in the head, neck, and shoulders. All patients have malformed great toes. Most patients have a spontaneous mutation of the ACVR1 gene. We report a 17-year-old girl with malformed great toes who had her first episode of heterotopic ossification and impaired mobility of the left hip at the age of 13 years. No inflammatory fibroproliferative masses preceded the onset of heterotopic ossification. Radiographic studies demonstrated myositis ossificans, but failure to associate the great toe malformation with heterotopic ossification led to a failure to diagnose FOP. She underwent repeated and unnecessary operative procedures to remove a recurrent lesion. FOP was finally suspected when the great toe malformation was correlated with the trauma-induced heterotopic ossification. Genetic analysis confirmed the presence of the classic FOP mutation (ACVR1 c.617G>A; R206H). This case highlights the importance of examining the great toes in anyone with heterotopic ossification. The association of malformations of the great toe with heterotopic ossification in all cases of classic FOP will lead to prompt clinical diagnosis and the prevention of iatrogenic harm.

  11. Nonlinear Progressive Collapse Analysis Including Distributed Plasticity

    Directory of Open Access Journals (Sweden)

    Mohamed Osama Ahmed


    Full Text Available This paper demonstrates the effect of incorporating distributed plasticity in nonlinear analytical models used to assess the potential for progressive collapse of steel framed regular building structures. Emphasis on this paper is on the deformation response under the notionally removed column, in a typical Alternate Path (AP method. The AP method employed in this paper is based on the provisions of the Unified Facilities Criteria – Design of Buildings to Resist Progressive Collapse, developed and updated by the U.S. Department of Defense [1]. The AP method is often used for to assess the potential for progressive collapse of building structures that fall under Occupancy Category III or IV. A case study steel building is used to examine the effect of incorporating distributed plasticity, where moment frames were used on perimeter as well as the interior of the three dimensional structural system. It is concluded that the use of moment resisting frames within the structural system will enhance resistance to progressive collapse through ductile deformation response and that it is conserative to ignore the effects of distributed plasticity in determining peak displacement response under the notionally removed column.

  12. Grand unified models including extra Z bosons

    International Nuclear Information System (INIS)

    Li Tiezhong


    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

    Usami, Masahiro

    Fossil fuels including coal play a key role as crucial energies in contributing to economic development in Asia. On the other hand, its limited quantity and the environmental problems causing from its usage have become a serious global issue and a countermeasure to solve such problems is very much demanded. Along with the pursuit of sustainable development, environmentally-friendly use of highly efficient fossil resources should be therefore, accompanied. Kyushu-university‧s sophisticated research through long years of accumulated experience on the fossil resources and environmental sectors together with the advanced large-scale commercial and empirical equipments will enable us to foster cooperative research and provide internship program for the future researchers. Then, this program is executed as a consignment business from the Ministry of Economy, Trade and Industry from 2007 fiscal year to 2009 fiscal year. The lecture that uses the textbooks developed by this program is scheduled to be started a course in fiscal year 2010.

  14. Should Broca's area include Brodmann area 47? (United States)

    Ardila, Alfredo; Bernal, Byron; Rosselli, Monica


    Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47  connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

  15. Pulmonary disorders, including vocal cord dysfunction. (United States)

    Greenberger, Paul A; Grammer, Leslie C


    The lung is a very complex immunologic organ and responds in a variety of ways to inhaled antigens, organic or inorganic materials, infectious or saprophytic agents, fumes, and irritants. There might be airways obstruction, restriction, neither, or both accompanied by inflammatory destruction of the pulmonary interstitium, alveoli, or bronchioles. This review focuses on diseases organized by their predominant immunologic responses, either innate or acquired. Pulmonary innate immune conditions include transfusion-related acute lung injury, World Trade Center cough, and acute respiratory distress syndrome. Adaptive immunity responses involve the systemic and mucosal immune systems, activated lymphocytes, cytokines, and antibodies that produce CD4(+) T(H)1 phenotypes, such as for tuberculosis or acute forms of hypersensitivity pneumonitis, and CD4(+) T(H)2 phenotypes, such as for asthma, Churg-Strauss syndrome, and allergic bronchopulmonary aspergillosis.
