Desserte ferroviaire à grande vitesse, activation des ressources spécifiques et développement du tourisme : le cas de l’agglomération rémoise High speed rail service, specific resources activation, and tourist development: the case of Rheims

Directory of Open Access Journals (Sweden)

Full Text Available La LGV est-européenne a été mise en service le 10 juin 2007. Les acteurs économiques des territoires desservis attendent beaucoup de cette arrivée notamment en matière de développement des tourismes urbain et d’affaires. Mais un tel développement n’est pas automatique. C’est l’appropriation collective de l’innovation que constitue la desserte à grande vitesse dans un territoire qui est au coeur de ses effets positifs. En effet, cette appropriation collective constitue une innovation relationnelle de laquelle peuvent naître des innovations de services complémentaires en matière de tourisme susceptibles de valoriser les ressources spécifiques existantes (patrimoine historique, culturel, gastronomique, etc.. Ainsi, si l’existence de ressources spécifiques joue un rôle pour les villes desservies, les efforts coordonnés des acteurs pour favoriser la “mise en tourisme” de la ville sont également décisifs. L’analyse est illustrée par le cas de l’agglomération rémoise.The East European High-Speed Rail started on June 10, 2007. Economic actors of beneficiary territories are expecting a lot of positive effects such as the development of urban and business tourisms. But such development is not automatic. The collective appropriation of the innovations linked to a High-Speed Rail Service seems to be central for generating positive effects. Indeed, this collective appropriation constitutes a relational innovation, which may give birth to additional services innovations in tourism that could enhance the value of existing specific resources (historical, cultural, gastronomic, etc. and turn them into assets. Thus, if the availability of specific resources plays a specific role for the connected cities, coordinated efforts of actors to promote the tourist development of the city are also decisive. We will illustrate our subject with the case of Rheims.

The NMR probe is the intrinsic part of the NMR system which allows transmission of a stimulus to a sample and the reception of a resulting signal from a sample. NMR probes are used in both imaging and spectroscopy. Optimal probe design is important to the production of adequate signal/moise. It is important for anyone using NMR techniques to understand how NMR probes work and how to optimize probe design

Deployment of a Long-Term Broadband Seafloor Observatory in Monterey Bay

Science.gov (United States)

McGill, P.; Neuhauser, D.; Stakes, D.; Romanowicz, B.; Ramirez, T.; Uhrhammer, R.

2002-12-01

MOBB (Monterey bay Ocean floor Broad Band project) is a collaborative project between the Monterey Bay Aquarium Research Institute (MBARI) and the Berkeley Seismological Laboratory (BSL). Its goal is to install and operate a permanent seafloor broadband seismic station as a first step towards extending the on-shore broadband seismic network in northern California to the seaside of the North-America/Pacific plate boundary, providing better azimuthal coverage for regional earthquake and structure studies. The successful MOBB deployment took place 40km off shore at a water depth of 1000m during three dives on April 9-11, 2002. The seismometer was buried in a 60-cm deep caisson, which was later back filled with glass beads to stabilize the instrument. New tools, including a high-pressure water-jet excavator, were developed for the ROV Ventana to accomplish these tasks. The ocean-bottom MOBB station currently comprises a three-component seismometer package, a current-meter, and a recording and battery package. Data recovery dives, during which the recording and battery package will be exchanged, are planned every three months for the next three years. A differential pressure gauge (DPG) (Cox et al., 1984) will be deployed as part of the recording package during the next data recovery dive in September 2002. The station is currently recording data autonomously. Eventually, it will be linked to the planned (and recently funded) MARS (Monterey Accelerated Research System; rl {http://www.mbari.org/mars/}) cable and provide real-time, continuous seismic data to be merged with the rest of the northern California real-time seismic system. The data are archived at the NCEDC for on-line availability, as part of the Berkeley Digital Seismic Network (BDSN). This project follows the 1997 MOISE experiment, in which a three-component broadband system was deployed for a period of three months, 40km off shore in Monterey Bay. MOISE was a cooperative program sponsored by MBARI, UC

Additional absorption of cosmic radio moises at microturbulences of ionosphere plasma

International Nuclear Information System (INIS)

Berezhko, E.G.; Gel'berg, M.G.; Krymskij, G.F.

1987-01-01

Electromagnetic wave interaction with a turbulent plasma of the ionosphere is considered. Electron scattering on plasma microturbulences is shown to result in supplementary wave absorption as compared with usual absorption conditioned by pair collisions. Effective frequency of collisions describing supplementary absorption essentially depends on frequency of the electromagnetic wave. The conducted estimations show that under the conditions of the high-latitude ionosphere accountancy of collective collisions may be important, particularly, it permits to explain anomalously steep spectra of riometric absorption

Isotopic study of water evaporation in a clayey soil, experimentation and modelling

International Nuclear Information System (INIS)

Mathieu, R.; Bariac, T.

1995-01-01

The isotopic theory of soil water evaporation in steady-state was applied to the quantification of shallow water table discharge rates in arid and semi-arid climates. This approach is limited by the time needed by the soil to reach the steady state after the last significant rain event. The 1D numerical model ''Moise'', proposed here, was developed for the simulation of the vertical profiles of water and stable isotope contents in a drying soil for any initial profile and atmospheric condition. Six non-perturbed soil columns of 1.1 m length were taken from Barogo, Burkina Faso and were saturated in the laboratory by infiltration and free drainage of pounding water and then allowed to evaporate freely. The columns were then sequentially sampled after 11, 42, 92, 162 and 253 days of drying for 18 O and 2 H isotopic analyses. 18 O profiles show an exponential shape during the first drying stage with a maximum isotopic enrichment at the surface. During the second drying stage, the penetration of very depleted atmospheric vapor tends to lower the isotopic content at the surface. The water and isotopic content were simulated with the Moise model. The model satisfactory reproduces the hydrodynamic evolution and the qualitative evolution of soil water isotopic content, but it largely overestimates the overall enrichment. It is thus plausible that a fraction of the soil water may keep its own isotopic composition with restricted exchanges with the surrounding mobile water and vapor, while a mobile phase can be affected by the isotopic enrichment.

Full Text Available It was studied the ecology and phenology, the flight periods of the Macrolepidoptera during the period 2000-20012 in the Natural Park „Dumbrava Sibiului”. The natural conditions and the specific features were mentioned in my previous papers (Stancă-Moise, 2000, 2002, 2003, 2004, 2007, 2010, 2011, 2012. There is no doubt that the appearance of the different species of Macrolepidoptera in different periods of time is in a direct relation with the succession of the climatic conditions. The flight periods express the biological specific feature of each species of Lepidoptera, being in direct connection with the activity of feeding and reproduction of imagos.

Stochastic kinetics

International Nuclear Information System (INIS)

Colombino, A.; Mosiello, R.; Norelli, F.; Jorio, V.M.; Pacilio, N.

1975-01-01

A nuclear system kinetics is formulated according to a stochastic approach. The detailed probability balance equations are written for the probability of finding the mixed population of neutrons and detected neutrons, i.e. detectrons, at a given level for a given instant of time. Equations are integrated in search of a probability profile: a series of cases is analyzed through a progressive criterium. It tends to take into account an increasing number of physical processes within the chosen model. The most important contribution is that solutions interpret analytically experimental conditions of equilibrium (moise analysis) and non equilibrium (pulsed neutron measurements, source drop technique, start up procedures)

A local town councillor describes the setting up of a wind farm in the south Pennines which plans to sell electricity to the local electricity suppliers. The Coal Clough wind farm will generate sufficient electricity to meet the average demand of 7,500 households and will be managed by a consortium known as Wind Resources Limited linking the construction company and the utilities aiming to buy the electricity produced. While wind power offers many environmental advantages over other means of power generation, local opposition was strong on the basis of the noise produced and clearly visible structures in an area designated as being of outstanding natural beauty.

A Riot of Our Own: a reflection on agency

Directory of Open Access Journals (Sweden)

Carol Tulloch

2014-10-01

Full Text Available The article is a reflection on the exhibition A Riot of Our Own, an archival narrative on the Rock Against Racism Movement (RAR that ran between 1976 and 1981. This was told through the exhibition-making collaboration between Syd Shelton, Ruth Gregory and Carol Tulloch. The exhibition drew solely on the RAR personal archive of Shelton and Gregory who were RAR (London committee members, key contributors to the graphic design of RAR and Shelton took photographs of the movement’s events and contextual material. The exhibition was first shown in 2008 at the CHELSEA Space Gallery, London, and went on tour to venues in London and Croatia. The paper traces the tenacious pursuit of anti-racist agency of RAR that has not lost its historical relevancy in the twenty-first century. What is discussed here is the black and white dynamic of difference as unity against the intolerance of difference that marked Britain during this period; why and how the exhibition A Riot of Our Own was produced in response to an open invitation from CHELSEA Space; the critical, curatorial and auto/biographical frameworks that informed this instance of exhibition-making. As a reflective article by the co-curator and collaborator of the exhibition, the writing of this article is an opportunity to look back on how the exhibition-making process produced new forces – the need to exercise agency as a connecting thread between the impetus of experimentation, the concept of ‘the edge’ and exhibition-making as a liminal space. The article contributes to the developing area of study in histories of exhibitions and ‘design activism’.

Analysis of piezoelectric energy harvester under modulated and filtered white Gaussian noise

Science.gov (United States)

Quaranta, Giuseppe; Trentadue, Francesco; Maruccio, Claudio; Marano, Giuseppe C.

2018-05-01

This paper proposes a comprehensive method for the electromechanical probabilistic analysis of piezoelectric energy harvesters subjected to modulated and filtered white Gaussian noise (WGN) at the base. Specifically, the dynamic excitation is simulated by means of an amplitude-modulated WGN, which is filtered through the Clough-Penzien filter. The considered piezoelectric harvester is a cantilever bimorph modeled as Euler-Bernoulli beam with a concentrated mass at the free-end, and its global behavior is approximated by the fundamental vibration mode (which is tuned with the dominant frequency of the dynamic input). A resistive electrical load is considered in the circuit. Once the Lyapunov equation of the coupled electromechanical problem has been formulated, an original and efficient semi-analytical procedure is proposed to estimate mean and standard deviation of the electrical energy extracted from the piezoelectric layers.

Since the development of resistance against mouse hepatitis virus (JHMV strain) coincides with the maturation of the immune system, we studied the possible role of distinct immunological components in the resistance of adult mice during JHMV infection. Adult C3H mice naturally resistant to JHMV were rendered susceptible to infection by lethal {sup 60}Co-irradiation and were subsequently reconstituted with limiting numbers of syngeneic bone marrow cells or spleen cells. Resistance or susceptibility dependend on the number of cells used for reconstitution and the interval between reconsitution and infection. Spleen cells from suckling mice affected neither resistance nor susceptibility and peritoneal cells from adult mice and thymus cells reduced resistance. Persistence of JHMV was demonstrated by virus reactivation. Animals infected with JHMV only once before being rendered immunoincompetent showed a different pattern of resistance. One to four months after infection, 15 to 35% of the animals died after reconstitution without having been reinfected, and persisting JHMV was found in their liver, spleen and peritoneal exudate. The survivors (47 to 87%) were resistant to further JHMV infection during immunodeficiency. Animals immunized 3 times with JHMV before irradiation did not show virus reactivation and were fully resistant to JHMV reinfection after reconstitution. The level of neutralizing anti JHMV serum antibodies in the group of mice immunized only once was comparable with the level of those immunized 3 times. The role of macrophage activation and cell-mediated immunity in this model are discused as an explanation for the resistance to, and persistence of, JHMV. (author).

A new interstellar molecule, methylcyanoacetylene (CH 3 C 3 N), has been detected in the molecular cloud TMC-1. The J = 8 → 7, J = 7 → 6, J = 6 → 5, and J = 5 → 4 transitions have been observed. For the first three of these, both the K = 0 and K = 1 components are present, while for J = 5 → 4, only the K = 0 line has been detected. The observed frequencies were calculated by assuming a value of radial velocity V/sub lSR/ = 5.8 km s -1 for TMC-1, typical of other molecules in the cloud. All Observed frequencies are within 10 kHz of the calculated frequencies, which are based on the 1982 laboratory constants of Moises et al., so the identification is secure. The lines are broadened by hyperfine splitting, and the J = 5 → 4, K = 0 transition shows incipient resolution into three hyperfine components. The rotational temperature determined from these observations is quite low, with 2.7 K 12 cm -2

After the first episode of shoulder dislocation, a combination of lesions can lead to chronic instability. The management in treatment of young athletes after the first acute anterior shoulder dislocation is controversial. The available literature supports early surgical treatment for young male athletes engaged in highly demanding physical activities after the first episode of traumatic dislocation of the shoulder. This is because of the best functional results and lower recurrence rates obtained with this treatment in this population. However, further clinical trials of good quality comparing surgical versus nonsurgical treatment for well-defined lesions are needed, especially for categories of patients who have a lower risk of recurrence.Keywords: athlete, conservative treatment, surgical treatment, immobilization, stabilization, primary treatment, shoulder dislocation

Tonal Scales and Minimal Simple Pitch Class Cycles

DEFF Research Database (Denmark)

Meredith, David

2011-01-01

Numerous studies have explored the special mathematical properties of the diatonic set. However, much less attention has been paid to the sets associated with the other scales that play an important rôle in Western tonal music, such as the harmonic minor scale and ascending melodic minor scale....... This paper focuses on the special properties of the class, T, of sets associated with the major and minor scales (including the harmonic major scale). It is observed that T is the set of pitch class sets associated with the shortest simple pitch class cycles in which every interval between consecutive pitch...... classes is either a major or a minor third, and at least one of each type of third appears in the cycle. Employing Rothenberg’s definition of stability and propriety, T is also the union of the three most stable inversional equivalence classes of proper 7-note sets.

Radiation stabilization effects in an ethylene-propylene copolymer and in epoxy resin particulate composites

International Nuclear Information System (INIS)

Baccaro, S.; Bianchilli, B.; Casadio, C.; Rinaldi, G.

1999-01-01

The aim of this work was to investigate the post-g-irradiation behavior of an ethylene-propylene copolymer loaded with an antioxidant containing the -NH functional group. The oxidative degradation of the polymer was studied using Infrared Absorption Spectroscopy. The shape of the oxidation profiles, and the dependence on thickness and on dose rate were in good agreement with the Gillen and Clough model. The interaction of polymeric free radicals with the antioxidant led to the formation of R-NO . stable radicals. These species are easily detectable using Electron Spin Resonance Spectroscopy. We used this technique to study the influence of the total absorbed dose, of dose rate and of oxygen and the time evolution of the oxidation products. High Performance Liquid Chromatography allowed us to determine the amount of antioxidant not involved in the oxidation reaction as a function of the total absorbed dose. The stabilization toward gamma radiation effects, of different types of curing agents for epoxide resins, and of fly ash as filler, were also investigated through monitoring the mechanical properties of such composite materials.

Recent developments in the line-by-line modeling of outgoing longwave radiation

Buehler, S.A.; Engeln, A. von; Brocard, E.; John, V.O.; Kuhn, T.; Eriksson, P.

2006-01-01

High frequency resolution radiative transfer model calculations with the Atmospheric Radiative Transfer Simulator (ARTS) were used to simulate the clear-sky outgoing longwave radiative flux (OLR) at the top of the atmosphere. Compared to earlier calculations by Clough and coworkers the model used a spherical atmosphere instead of a plane parallel atmosphere, updated spectroscopic parameters from HITRAN, and updated continuum parameterizations from Mlawer and coworkers. These modifications lead to a reduction in simulated OLR by approximately 4.1%, the largest part, approximately 2.5%, being due to the absence of the plane parallel approximation. As a simple application of the new model, the sensitivity of OLR to changes in humidity, carbon dioxide concentration, and temperature were investigated for different cloud-free atmospheric scenarios. It was found that for the tropical scenario a 20% change in humidity has a larger impact than a doubling of the carbon dioxide concentration. The sensitive altitude region for temperature and humidity changes is the entire free troposphere, including the upper troposphere where humidity data quality is poor

The goalkeepers are more exposed to shoulder disorders than other field players. Injury prevention exercises for upper limbs were cited in few studies involving throwing athletes, but we know that goalkeepers need a specific program. The purpose of this study is to describe the development of an adapted Fédération Internationale de Football Association (FIFA 11+ program, namely the FIFA 11+ shoulder, which targets the prevention of shoulder injuries in soccer goalkeepers. The FIFA 11+ shoulder program is structured into three parts: general warming-up exercises, exercises to improve strength and balance of the shoulder, elbow, wrist, and finger muscles, and advanced exercises for core stability and muscle control. The exercises were selected based on recommendations from studies demonstrating high electromyographic activity. Keywords: goalkeeper, shoulder, injury prevention, prevention program

The water vapour self-continuum absorption in the infrared atmospheric windows: new laser measurements near 3.3 and 2.0 µm

The amplitude, the temperature dependence, and the physical origin of the water vapour absorption continuum are a long-standing issue in molecular spectroscopy with direct impact in atmospheric and planetary sciences. In recent years, we have determined the self-continuum absorption of water vapour at different spectral points of the atmospheric windows at 4.0, 2.1, 1.6, and 1.25 µm, by highly sensitive cavity-enhanced laser techniques. These accurate experimental constraints have been used to adjust the last version (3.2) of the semi-empirical MT_CKD model (Mlawer-Tobin_Clough-Kneizys-Davies), which is widely incorporated in atmospheric radiative-transfer codes. In the present work, the self-continuum cross-sections, CS, are newly determined at 3.3 µm (3007 cm-1) and 2.0 µm (5000 cm-1) by optical-feedback-cavity enhanced absorption spectroscopy (OFCEAS) and cavity ring-down spectroscopy (CRDS), respectively. These new data allow extending the spectral coverage of the 4.0 and 2.1 µm windows, respectively, and testing the recently released 3.2 version of the MT_CKD continuum. By considering high temperature literature data together with our data, the temperature dependence of the self-continuum is also obtained.

Para efetuar uma comparação entre as três teorias e apurar as condições mais apropriadas de uso das mesmas, realizou-se um experimento de campo com um trator de tração simples (4x2, com o controle de um número apreciável de variáveis relevantes, para criar condições de comparação com uma simulação posterior. No trabalho de campo, foram utilizados tratamentos que envolviam a condição do solo, preparado ou consolidado; pneus do tipo diagonal, e a deflexão desse pneu, maior e menor.

Parameter identification of a BWR nuclear power plant model for use in optimal control

International Nuclear Information System (INIS)

Volf, K.

1976-02-01

The problem being considered is the modeling of a nuclear power plant for the development of an optimal control system of the plant. Current system identification concepts, combining input/output information with a-priori structural information are employed. Two of the known parameter identification methods i.e., a least squares method and a maximum likelihood technique, are studied as ways of parameter identification from measurement data. A low order state variable stochastic model of a BWR nuclear power plant is presented as an application of this approach. The model consists of a deterministic and a noise part. The deterministic part is formed by simplified modeling of the major plant dynamic phenomena. The moise part models the effects of input random disturbances to the deterministic part and additive measurement noise. Most of the model parameters are assumed to be initially unknown. They are identified using measurement data records. A detailed high order digital computer simulation is used to simulate plant dynamic behaviour since it is not conceivable for experimentation of this kind to be performed on the real nuclear power plant. The identification task consists in adapting the performance of the simple model to the data acquired from this plant simulation ensuring the applicability of the techniques to measurement data acquired directly from the plant.

Three sources of data were used to inform the intervention development process: the existing research literature on school-based physical activity interventions, teacher interviews (N=12 and pupil focus groups (N=18 and an experimental feasibility study (N=85; Norris, Shelton, Dunsmuir, Duke-Williams, & Stamatakis, 2015b. The Behaviour Change Wheel was used as a framework to guide synthesis of evidence into the resulting intervention. Potential appropriate Behaviour Change Techniques were reviewed and embedded within the intervention. Conclusions The resulting 6-week Virtual Traveller programme with a 3-month follow-up period is currently in its final stages of evaluation in ten Greater London primary schools. Using the Behaviour Change Wheel and Behaviour Change Techniques allows development of replicable health interventions in applied settings such as schools.

The Hysteresis Performance and Restoring Force Model for Corroded Reinforced Concrete Frame Columns

Directory of Open Access Journals (Sweden)

Guifeng Zhao

2016-01-01

Full Text Available A numerical simulation of the hysteresis performance of corroded reinforced concrete (RC frame columns was conducted. Moreover, the results obtained were compared with experimental data. On this basis, a degenerated three-linearity (D-TRI restoring force model was established which could reflect the hysteresis performance of corroded RC frame columns through theoretical analysis and data fitting. Results indicated that the hysteretic bearing capacity of frame columns decreased significantly due to corrosion of the rebar. In view of the characteristics of the hysteresis curve, the plumpness of the hysteresis loop for frame columns decreased and shrinkage increased with increasing rebar corrosion. All these illustrated that the seismic energy dissipation performance of frame columns reduced but their brittleness increased. As for the features of the skeleton curve, the trends for corroded and noncorroded members were basically consistent and roughly corresponded to the features of a trilinear equivalent model. Thereby, the existing Clough hysteresis rule can be used to establish the restoring force model applicable to corroded RC frame columns based on that of the noncorroded RC members. The calculated skeleton curve and hysteresis curve of corroded RC frame columns using the D-TRI model are closer to the experimental results.

The Greensboro Quadrangle, North Carolina and Virginia, was evaluated to identify and delineate areas favorable for the occurrence of uranium deposits. General surface reconnaissance and geochemical sampling were carried out in all geologic environments within the quadrangle. Aerial radiometric and hydrogeochemical and stream-sediment reconnaissance data were analyzed, and ground-truth followup studies of anomalies were conducted. Detailed surface investigations, log and core studies, and a radon emanometry survey were conducted in selected environments. The results of this investigation suggest environments favorable for allogenic uranium deposits in metamorphic rocks adjacent to the intrusive margins of the Rolesville, Castalia, Redoak, and Shelton granite plutons, and sandstone-type deposits in the sediments of the Durham and Dan River Triassic basin systems. Environments in the quadrangle considered unfavorable for uranium deposits are pegmatites and metamorphic rocks and their included veins associated with fault and shear zones

The static and dynamic first (β{sub ‖}) and second (γ{sub ‖}) hyperpolarizabilities of water, methanol, and dimethyl ether have been evaluated within the response function approach using a hierarchy of coupled cluster levels of approximation and doubly augmented correlation consistent atomic basis sets. For the three compounds, the electronic β{sub ‖} and γ{sub ‖} values calculated at the CCSD and CC3 levels are in good agreement with gas phase electric field-induced second harmonic generation (EFISHG) measurements. In addition, for dimethyl ether, the frequency dispersion of both properties follows closely recent experimental values [V. W. Couling and D. P. Shelton, J. Chem. Phys. 143, 224307 (2015)] demonstrating the reliability of these methods and levels of approximation. This also suggests that the vibrational contributions to the EFISHG responses of these molecules are small.

The evaluation an improvement of radiative transfer calculations are essential to attain improved performance of general circulation models (GCMs) for climate change applications. A Quality Measurement Experiment (QME) is being conducted to analyze the spectral residuals between the downwelling longwave radiance measured by the University of Wisconsin Atmospheric Emitted Radiance Interferometer (AERI) and spectral radiance calculated by the Line-By-Line Radiative Transfer Model (LBLRTM). The three critical components of this study are (1) the assessment of the quality of the high resolution AERI measurements, (2) the assessment of the ability to define the atmospheric state in the radiating column, and (3) the evaluation of the capability of LBLRTM. Validations have been performed on spectral radiance data, obtained from April 1994 through July 1994, through the analysis of the spectral interval and physical process. The results are archived as a function of time, enabling the retrieval of specific data and facilitating investigations and diurnal effects, seasonal effects, and longer-term trends. While the initial focus is restricted to clear-sky analyses, efforts are under way to include the effects of clouds and aerosols. Plans are well formulated for the extension of the current approach to the shortwave. An overview of the concept of the QME is described by Miller et al. (1994), and a detailed description of this study is provided by Clough et al. (1994).

Full Text Available Abstract Background The Agrobacterium vacuum (Bechtold et al 1993 and floral-dip (Clough and Bent 1998 are very efficient methods for generating transgenic Arabidopsis plants. These methods allow plant transformation without the need for tissue culture. Large volumes of bacterial cultures grown in liquid media are necessary for both of these transformation methods. This limits the number of transformations that can be done at a given time due to the need for expensive large shakers and limited space on them. Additionally, the bacterial colonies derived from solid media necessary for starting these liquid cultures often fail to grow in such large volumes. Therefore the optimum stage of plant material for transformation is often missed and new plant material needs to be grown. Results To avoid problems associated with large bacterial liquid cultures, we investigated whether bacteria grown on plates are also suitable for plant transformation. We demonstrate here that bacteria grown on plates can be used with similar efficiency for transforming plants even after one week of storage at 4°C. This makes it much easier to synchronize Agrobacterium and plants for transformation. DNA gel blot analysis was carried out on the T1 plants surviving the herbicide selection and demonstrated that the surviving plants are indeed transgenic. Conclusion The simplified method works as efficiently as the previously reported protocols and significantly reduces the workload, cost and time. Additionally, the protocol reduces the risk of large scale contaminations involving GMOs. Most importantly, many more independent transformations per day can be performed using this modified protocol.

Research on human navigation has indicated that males and females differ in self-reported navigation strategy as well as objective measures of navigation efficiency. In two experiments, we investigated sex differences in navigation strategy and efficiency using an objective measure of strategy, the dual-solution paradigm (DSP; Marchette, Bakker, & Shelton, 2011). Although navigation by shortcuts and learned routes were the primary strategies used in both experiments, as in previous research on the DSP, individuals also utilized route reversals and sometimes found the goal location as a result of wandering. Importantly, sex differences were found in measures of both route selection and navigation efficiency. In particular, males were more likely to take shortcuts and reached their goal location faster than females, while females were more likely to follow learned routes and wander. Self-report measures of strategy were only weakly correlated with objective measures of strategy, casting doubt on their usefulness. This research indicates that the sex difference in navigation efficiency is large, and only partially related to an individual's navigation strategy as measured by the dual-solution paradigm.

Omalizumab is a recombinant humanized anti-immunoglobulin E (IgE antibody that binds to the Cε3 domain of the IgE heavy chain and prevents it from binding to its high-affinity receptor FcεRI. It has been largely studied in the field of asthma and is currently approved for the treatment of both adult and pediatric (children; >6-year-old patients. In addition, in recent, well-controlled clinical trials in patients with CSU resistant to antihistamines, add-on therapy with subcutaneous omalizumab significantly reduced the severity of itching, and the number and size of hives, and increased patients’ health-related QoL and the proportion of days free from angioedema compared with placebo, with an excellent tolerance. Thus, omalizumab is an effective and well-tolerated add-on therapy for patients with CSU who are symptomatic despite background therapy with H1 antihistamines. In this review, we cover the following points: epidemiology, pathogenesis, assessment of activity, impact on QoL, and treatment of CSU, and finally, we focus on omalizumab in the treatment of CSU including the pharmacokinetic properties and mechanism of action, and use in pregnant women, nursing infants, and children.

Nitrous oxide (N2O) losses derived from grazing ruminant livestock urine patches account for 40% of global N2O emissions. It has been shown that Plantago lanceolata, an herb species used in grazed pastures, contains an active secondary metabolite (aucubin) that has the potential to be excreted by grazing ruminants and inhibit nitrification in the urine patch, a key step in soil N2O production. However, the urinary excretion rate of aucubin needed to significantly reduce urine patch N2O emissions remains unknown. Aucubin was dissolved in bovine urine at three rates (47, 243, and 486 kg ha-1), based on rates used in Dietz et al. (2013) and the calculated highest potential aucubin application rate, from Gardiner et al. (2017). A control, along with a urine treatment and the three aucubin treatments (all urine applied at 700 kg N ha-1), was applied to 20 g soil and incubated in the laboratory for 35 d. Soils were monitored for surface pH, inorganic N concentration (NH4+/NO3-), and gas (N2O and CO2) fluxes. This experiment is currently underway and the results will be presented at the conference.

Ozone injury to celery. [Apium graveolens

Ozone is the principal air pollutant damaging crops in Connecticut. Ozone injury in Connecticut has been found on a number of crops including tobacco, tomatoes, potatoes, spinach, alfalfa, and cereals. This is the first report of ozone damage to celery (Apium graveolens var. dulce) in Connecticut, and perhaps in the United States. On July 7, 1966, celery plants with badly damaged older leaves were found in a commercial garden near Shelton, Connecticut. The injured leaves showed chlorotic and necrotic interveinal areas on their upper surfaces. These areas were slightly depressed. Cross sections of the lesions revealed that the palisade cells were most severely injured. Spinach and carrots growing near the celery showed typical symptoms of ozone damage. To substantiate the diagnosis, young celery plants were exposed to 0.2 ppm of ozone in a well-lighted plastic chamber for 1 to 3 hours. Five days later, these plants developed symptoms indentical to those found on celery in the field. Ozone damage appeared on many crops in southern Connecticut early in July. This injury probably occurred on June 27, when a high concentration of ozone (0.1 ppm) was present in the New Haven area.

Participants completed a series of questionnaires assessing DT, MT, and PA.Results: Machiavellianism, narcissism, and psychopathy were all significantly associated with higher MT scores (rs =0.45, 0.50, and 0.20, respectively. DT traits and MT were associated with more vigorous PA. Compared to men, women participants had lower scores for DT traits (overall score and psychopathy, while no differences were found for MT or PA in both sexes.Conclusion: DT traits, high MT, and vigorous PA are interrelated. This pattern of results might explain why, for instance, successful professional athletes can at the same time be tough and ruthless.

Bone densitometry with the computer tomograph

Weiss, T.

This work tests the usefulness of the EMI head scanner MARK I for a quantitative detection of ossary mineral content. Twenty-three concentration levels of a aqueous K 2 HPO 4 -solution were positioned by means of a special clamping device at the EMI-scanner and examined at tubevoltages of 100, 120 and 140 kV. This produces an almost linear dependence between CT-unit and sample concentration, whereby it shows that the measured special element densities of samples with the same densities vary in dependence with the voltage. The examination of an anotomical fore-arm preperate served as a statement for the reproductability of computer tomographic densitometry at non-moving biological objects. The test of reproductability of bone densitometry measurements under clinical conditions was made on the occation of the six time examinations of the right hand fore-arm bone of a young dummy. Furthermore densitometric examination were made at the fore-arm shelton of 40 long-time dialysis patients in the age levels between 17 and 67 years. The reproductability of the technique presented here is at least not better with the EMI-head-scanner MARK I used here. A change is possible by using the new whole body tomographs. (orig./MG) [de

Impact of drying-rewetting events on the response of soil microbial functions to dairyfibre and Miscanthus biochars

dissolution of alkaline minerals, high ash content (Lehmann et al. 2011) and solubility of DOC. Biochar treatments buffered changes in pH caused by drying and flooding but resulted in an increase in DOC. Biochar in general stabilised glucosidase activity whilst Miscanthus biochar stimulated chitinase and phosphatase activity that may have been due to adsorption of either enzyme or substrate as observed by Bailey et al. (2011). Surprisingly, alkaline phosphatase activity was not stimulated by the rise in pH in the diaryfibre treatment and was lower than the control along with the other hydrolase enzymes suggesting that deprotonation of soil phenols at higher pH inhibited activity via the enzyme-latch mechanism that in peatlands explains low rates of decomposition (Freeman et al., 2001; Sinsabaugh et al. 2010). This was supported by observation of higher phenol oxidase activity within the dairyfibre treatment that increased in response to greater availability of substrate and/or increases in pH. All biochars inhibited the production of N2O that was stimulated by the supply of labile carbon from SIR, suggesting that biochar decreased C-substrate availability through adsorption at its surface (Clough and Condron, 2010). Overall, this study has shown that specific feedstocks may be used to produce biochars to control microbial functions in soil such as inhibiting hydrolase enzymes for carbon sequestration as occurs naturally in peatlands or suppress the production of the potent greenhouse gas N2O.

The subject of the theory of vibrations has carried an aesthetic appeal to generations of engineering students for its richness of ideas, and for the intellectual challenges it offers. Also, the diverse range of its applications (covering civil, mechanical, automotive, and aerospace structures) has provided obvious motivations for its study. For most students, the subject provides, perhaps, the first encounter in substantial application of mathematical tools (differential equations, calculus of variations, Fourier/Laplace transforms, and matrix algebra) to engineering problems. The intimate relationship that the subject of mechanics has with mathematics strikes home probably for the first time. While teaching this subject, the instructor is spoilt for choice in selecting a text book and so are the students who wish to pursue a self-study of the subject. Many luminaries in the field have offered their own exposition of the subject: starting from the classics of Rayleigh, Timoshenko, Den Hartog, Bishop and Johnson, and the works of more recent vintage (e.g., the books by Meirovich, Clough, and Penzien, and works with computational flavour, such as, those by Bathe and Petyt), several works easily come to one's mind. Given this milieu, it requires a distinctive conviction to write a new book on this subject. And, here we have a book, written by a practitioner, which aims to deal with fundamental aspects of vibrations of engineering systems. The scepticism that this reviewer had on the need for having one more such book vanished as he browsed through the book and read selectively a few sections. The author's gift for elegant explanations is immediately noticeable even in such a preliminary reading. After a more careful reading, the reviewer has found this book to be insightful and he considers the book to be a welcome addition to the family of books on vibration engineering. The author has struck a fine balance between physical explanations, mathematical niceties

This issue of JERHRE examines informed consent requirements as they arise in diverse countries and cultures, and in relation to level of risk of the research and vulnerability of the potential participants. It also examines issues of literacy as they affect informed consent. And it examines whether research participants want to be informed. Adequate informed consent is a statement that is meaningful and understandable by the particular research participant and that allows the participant free choice regarding participation. The way in which an adequate consent procedure is administered must, by definition, depend on the level of literacy of the potential research participants, and the nature and values of the culture of the potential participants. An implication of these requirements is that Western consent procedures are likely to violate ethical standards when employed in non-Western cultures. Educational activities presented below will enable readers to consolidate their knowledge and understanding of these issues. Written informed consent statements are not valid for use with research participants who lack literacy. The level of literacy required depends on the complexity of the research topic. In Clough et al., we find that cultural differences in self-concept, understanding of research methods, level of education, and deference to researchers challenge researchers to modify standard consent procedures to render them valid in some cultural contexts. In Abou Zeina et al., we find an even more complex problem of communicating patients' rights to illiterate patients in an Egyptian public hospital: not only can they not read, but they consider "patients' rights" as the least of their problems. In Iverson et al., we find still different issues concerning the scientific literacy of surrogate decision makers for critically ill patients. And in Ghandour et al., we find in Lebanon, within a very large sample of socioeconomically diverse students, a virtually total lack

The current methane retrieval algorithm (V1) at wavenumber range from 1210 cm-1 to 1360 cm-1 including CH4 ν 4 band from the thermal infrared (TIR) band of Thermal and Near-infrared Sensor for Carbon Observation Fourier Transform Spectrometer (TANSO-FTS) onboard Greenhouse Gases Observing Satellite (GOSAT) uses LBLRTM V12.1 with AER V3.1 line database and MT CKD 2.5.2 continuum absorption model to calculate optical depth. Since line parameter databases have been updated and the continuum absorption may have large uncertainty, the purpose of this study is to assess the impact on {CH}4 retrieval from the choice of line parameter databases and the uncertainty of continuum absorption. We retrieved {CH}4 profiles with replacement of line parameter database from AER V3.1 to AER v1.0, HITRAN 2004, HITRAN 2008, AER V3.2, or HITRAN 2012 (Rothman et al. 2005, 2009, and 2013. Clough et al., 2005), we assumed 10% larger continuum absorption coefficients and 50% larger temperature dependent coefficient of continuum absorption based on the report by Paynter and Ramaswamy (2014). We compared the retrieved CH4 with the HIPPO CH4 observation (Wofsy et al., 2012). The difference from HIPPO observation of AER V3.2 was the smallest and 24.1 ± 45.9 ppbv. The differences of AER V1.0, HITRAN 2004, HITRAN 2008, and HITRAN 2012 were 35.6 ± 46.5 ppbv, 37.6 ± 46.3 ppbv, 32.1 ± 46.1 ppbv, and 35.2 ± 46.0 ppbv, respectively. Maximum {CH}4 retrieval differences were -0.4 ppbv at the layer of 314 hPa when we used 10% larger absorption coefficients of {H}2O foreign continuum. Comparing AER V3.2 case to HITRAN 2008 case, the line coupling effect reduced difference by 8.0 ppbv. Line coupling effects were important for GOSAT TIR {CH}4 retrieval. Effects from the uncertainty of continuum absorption were negligible small for GOSAT TIR CH4 retrieval.

The Monterey ocean bottom broadband station (MOBB) was installed on the seafloor in Monterey Bay, 40 km offshore, and at a depth of 1000m from the sea surface, on April 9-11, 2002. Its success capitalizes on the experience gained in the 1997 International MOISE experiment, conducted under similar conditions. The deployment took place during 3 dives on consecutive days and made use of MBARI's Point Lobos ship and ROV Ventana. The station is currently recording data autonomously. Eventually, it will be linked to the planned (and recently funded) MARS (Monterey Accelerated Research System; \\url {http://www.mbari.org/mars/}) cable and provide real-time, continuous seismic data to be merged with the rest of the northern California real-time seismic system. The data are archived at the NCEDC for on-line availability, as part of the Berkeley Digital Seismic Network (BDSN). The ocean-bottom MOBB station currently comprises a three-component seismometer package, a current-meter, a DPG, and recording and battery packages. The seismic package contains a low-power (2.2W), three-component CMG-1T broadband seismometer system, built by Guralp, Inc., with a three-component 24-bit digitizer, a leveling system, and a precision clock. The seismometer package is mounted on a cylindrical titanium pressure vessel 54cm in height and 41 cm in diameter, custom built by the MBARI team and outfitted for underwater connection. Data recovery dives, during which the recording and battery package will be exchanged are planned every three months for the next 3 years. Three such dives have already taken place, on 06/27/02, 09/20/02 and on 01/07/03. Due to a software problem, data were lost during the time period 07/01/02 and 09/20/02. Many regional and teleseismic earthquakes have been well recorded and the mass position signals indicate that the instruments have progressively settled. Preliminary analysis of data retrieved during the 2002 summer and winter dives will be presented. In particular

Full Text Available Owing to the fact that there is currently no international treaty that provides a globally accepted substantive human right for the protection of the environment (Anton and Shelton, 2011; Turner, 2009 there is a case for considering how such a right could or should be developed. This paper considers certain aspects of the potential development of such a right by focussing on key non-state actors that make decisions, which can affect the environment. Consideration is given to three different types of non-state actors: companies (corporations, the World Trade Organisation (WTO and multilateral development banks (MDBs. It specifically examines their ‘constitutional’ purposes and the overall legal constraints that their decision-makers are bound to comply with, and where applicable, the legal obligations that they impose upon their members.Therefore, this approach to the issue focuses on the legal foundations that determine how such actors make decisions and how that can affect the environment. This paper provides a broad perspective to illustrate the commonalities between the actors that are discussed in relation to their decision-making processes. Ultimately it provides an argument in support of the formal development of an international treaty that would create a global substantive environmental right. However it posits that such a treaty should inter alia be designed and framed in a manner, that would develop reformed legal obligations for the types of non-state actors discussed. Debido al hecho de que actualmente no existe ningún tratado internacional que proporcione un derecho humano globalmente aceptado para la protección del medio ambiente (Anton y Shelton 2011, Turner 2009 hay un argumento para considerar cómo podría o debería desarrollarse tal derecho.

Do detalhe à história: Comentário do texto de Iannini “A psicanálise Freudiana entre ciência e arte”

Full Text Available Além do comentar o texto de Iannini sobre a convergência entre a atitude científica e o pensamento estético na escrita de Freud, o objetivo desse artigo é questionar a suposta confiabilidade de um critério meramente positivista de cientificidade na fundamentação do trabalho psicanalítico. Em um primeiro momento, acompanhando alguns de seus comentários estéticos, escritos sob o anonimato no seu ensaio sobre o Moises de Michelangelo, veremos como Freud admite que o método para o reconhecimento da autoria das obras de arte, desenvolvido pelo médico italiano Giovanni Morrelli, exerceu considerável influência sobre ele, antes mesmo da descoberta da psicanálise. Este método consistia na observação de detalhes singulares periféricos das obras de arte, do mesmo modo como a psicanálise dispensaria atenção a traços pouco notados e coisas secretas para lançar luz sobre o inconsciente. Mais tarde, esse mesmo método teria sido atribuído também ao tipo de investigação levada a cabo pelo Sherlock Holmes de Conan Doyle, ao ser batizado por Carlo Ginzburg de paradigma indiciário, ou método presuntivo. Em um segundo momento, entretanto, recusaremos essa mesma tradição sherlockiana, ao sugerir que a atitude científica de Freud deva ser reconhecida mais na lisura de seus procedimentos investigativos e na retidão intelectual, que o levava a reconhecer limitações e as falhas de toda a investigação, do que na resolução definitiva de um quebra-cabeças, e aproximaremos nossas análises à leitura hermenêutica e pragmática da psicanálise. Finalmente, tomaremos distância também dessa última, ao mostrar que a persistência da pesquisa arqueológica de Freud sobre o sentido dos sonhos, dos sintomas e dos distúrbios de memória para melhorar a dinâmica do tratamento aproxima a psicanálise da perspectiva materialista de Benjamin, que recusa a noção de tempo finito e fechado e linear, em apoio a uma concepção n

The seminar devoted to 'Irradiation Technologies and the IRASM Facility' aimed at debating the principal problems related to one of the most important project ever developed in Romania, at the Horia Hulubei National Institute of Physics and Nuclear Engineering, in collaboration with IAEA. IRASM (an acronym for Multiple Purpose Irradiation Facility) is using initially a 60 Co of 100 kCi irradiation source (to be replaced after an promotional stage by a 2 MCi Co source). It is designed to irradiate a materials volume of about 35,000 m 3 /year. Health, agriculture, food industry and materials industry are the most targeted customers. It will be used for sterilization of medical materials and pharmaceuticals products, peat and seed (and other agricultural products) decontamination and sterilization, experimental irradiation of food products, irradiation of composite plastics and other industrial products, etc. The seminar was a first meeting of Romanian specialists in radiation processing with potential users of these technologies as well as with decision making persons working with national governmental and regulation authorities. Twelve communications were presented as a basis for discussion. These were: 1. IRASM - a technical assistance IAEA project and the prospects for technological irradiation in Romania (Serban Dobrescu); 2. IRASM facility - goal, present stage, perspectives (Corneliu C. Ponta); 3. Nuclear safeguards and radioprotection at IRASM (Ioan Valentin Moise); 4. Nuclear safeguard policy for IRASM (Mariana Irimia, Gabriela Vladescu, Ion Cristian); 5. Technological dosimetry at IRASM (Rodica Macrin, Rodica Moraru, Nicolae Valcov); 6. Quality assurance in building and exploiting IRASM (Ioana Domsa); 7. Current status of irradiation technologies in IFIN-HH (Mitica Dragusin); 8. Chemical-pharmaceutical, cosmetic and medical product sterilization (Paul Adrian, Eleonora Gheorghiu); 9.

Journeys Across Difference: Pre-service Teacher Education Students’ Perceptions of a Pedagogy of Discomfort in a Digital Storytelling Project in South Africa

Full Text Available Engaging with difference is an important skill for teachers in current South Africa. Critics of the dominant approach to teaching on and with difference in pre-service teacher education argue that it mostly promotes de-contextualised celebrations of diverse cultures without addressing critical issues of power and social forces. One of the reasons that educators shy away from engaging with issues of power and privilege in the classroom is the fear of highly explosive emotions that might emerge in the process. In South Africa this is compounded by the legacy of racial discrimination, still impacting on today’s social engagements of students. However, proponents of the ‘affective turn’ (Berlant 2008; Ahmed 2004; Ahmed 2010; Clough and Halley 2007; Gregg and Seigworth 2010 in the Social Sciences argue, that it is important to work with the emotions that govern our classrooms, for social transformation in students to happen. Boler and Zembylas’ ‘pedagogy of discomfort’ (2003 for example stipulates that for social transformation to happen both students and educators have to step out of their comfort zone, to experience discomforting emotions, and recognizes the value of both cognitive and emotional labour for learning about difference. This study is piloting an innovative approach for teaching on and with difference in a South African pre-service teacher education classroom, combining a digital storytelling process with participatory learning and action techniques and a reflective essay. Framed by Boler and Zembylas’ (2003 work on the politics of emotions and feminist writings on the role of affect and public feelings, we explored how students experienced and negotiated their cognitive and emotional journey in this project. An interpretive analysis of data collected through focus groups with selected students revealed that this classroom was a highly divided, complex and contested space, in which students identified strongly along racial

Long known as a fully polarized band with a near vanishing depolarization ratio [ηs = 0.05, W. Holzer and R. Ouillon, Chem. Phys. Lett. 24, 589 (1974)], the 2ν5 Raman overtone of SF6 has so far been considered as of having a prohibitively weak anisotropic spectrum [D. P. Shelton and L. Ulivi, J. Chem. Phys. 89, 149 (1988)]. Here, we report the first anisotropic spectrum of this overtone, at room temperature and for 13 gas densities ranging between 2 and 27 amagat. This spectrum is 10 times broader and 50 times weaker than the isotropic counterpart of the overtone [D. Kremer, F. Rachet, and M. Chrysos, J. Chem. Phys. 138, 174308 (2013)] and its profile much more sensitive to pressure effects than the profile of the isotropic spectrum. From our measurements an accurate value for the anisotropy matrix-element |⟨000020|Δα|000000⟩| was derived and this value was found to be comparable to that of the mean-polarizability | |. Among other conclusions our study offers compelling evidence that, in Raman spectroscopy, highly polarized bands or tiny depolarization ratios are not necessarily incompatible with large polarizability anisotropy transition matrix-elements. Our findings and the way to analyze them suggest that new strategies should be developed on the basis of the complementarity inherent in independent incoherent Raman experiments that run with two different incident-beam polarizations, and on concerted efforts to ab initio calculate accurate data for first and second polarizability derivatives. Values for these derivatives are still rarities in the literature of SF6.

The thermal infrared (TIR) band of Thermal and Near-infrared Sensor for Carbon Observation Fourier Transform Spectrometer (TANSO-FTS) onboard Greenhouse Gases Observing Satellite (GOSAT) observes CH4 profile at wavenumber range from 1210 cm-1 to 1360 cm-1 including CH4 ν4 band. The current retrieval algorithm (V1.0) uses LBLRTM V12.1 with AER V3.1 line database to calculate optical depth. LBLRTM V12.1 include MT_CKD 2.5.2 model to calculate continuum absorption. The continuum absorption has large uncertainty, especially temperature dependent coefficient, between BPS model and MT_CKD model in the wavenumber region of 1210-1250 cm-1(Paynter and Ramaswamy, 2014). The purpose of this study is to assess the impact on CH4 retrieval from the line parameter databases and the uncertainty of continuum absorption. We used AER v1.0 database, HITRAN2004 database, HITRAN2008 database, AER V3.2 database, and HITRAN2012 database (Rothman et al. 2005, 2009, and 2013. Clough et al., 2005). AER V1.0 database is based on HITRAN2000. The CH4 line parameters of AER V3.1 and V3.2 databases are developed from HITRAN2008 including updates until May 2009 with line mixing parameters. We compared the retrieved CH4 with the HIPPO CH4 observation (Wofsy et al., 2012). The difference of AER V3.2 was the smallest and 24.1 ± 45.9 ppbv. The differences of AER V1.0, HITRAN2004, HITRAN2008, and HITRAN2012 were 35.6 ± 46.5 ppbv, 37.6 ± 46.3 ppbv, 32.1 ± 46.1 ppbv, and 35.2 ± 46.0 ppbv, respectively. Compare AER V3.2 case to HITRAN2008 case, the line coupling effect reduced difference by 8.0 ppbv. Median values of Residual difference from HITRAN2008 to AER V1.0, HITRAN2004, AER V3.2, and HITRAN2012 were 0.6 K, 0.1 K, -0.08 K, and 0.08 K, respectively, while median values of transmittance difference were less than 0.0003 and transmittance differences have small wavenumber dependence.

The findings of a 14-year study of tree reproduction and survival in the Platte River, Nebraska, are presented. The study was initiated in 1985 to determine the causes and remedies of woodland expansion and channel narrowing, which have reduced potential roosting habitat for migratory avifauna such as the whooping crane and sandhill crane.A total of 296 relocatable sites, constituting some 600 plots with Populus and Salix seedlings, was selected and sampled within two reaches near Shelton and Odessa, Nebraska. The fate of some 37 000 tree seedlings was monitored within the plot network.Tree recruitment is controlled largely by stream flow in June. Populus and Salix produce large numbers of seedlings in the river bed in most years, indicating the potential for high rates of woodland expansion. On average, in only 1 year in 7 is stream flow in June high enough to preclude Populus and Salix recruitment.Seedling mortality is dominated by two environmental factors: summer stream flow pulses from thunderstorms, which erode or bury new germinants, and river bed restructuring by moving ice in winter. A third factor, seedling mortality by desiccation during summer droughts, does occur but at a low frequency.Plots of seedlings had extremely low survival rates over the course of the study. Forty-two per cent of the plots lost all seedlings by the first remeasurement (July to September), 36% by the second measurement (May), and 10% by the third remeasurement (July). Thus nearly 90% of the plots had lost all tree seedlings by the end of the first year.counterbalanced by erosion of established woodland.effectiveness of prescribed flows as insurance against future narrowing. Flows prescribed at key times to raise seedling mortality rates are recommended to maintain or widen channels, rather than mechanical clearing of established woodland.

The bedrock geologic map of the Lisbon quadrangle, and parts of the Sugar Hill and East Haverhill quadrangles, Grafton County, New Hampshire, covers an area of approximately 73 square miles (189 square kilometers) in west-central New Hampshire. This map was created as part of a larger effort to produce a new bedrock geologic map of Vermont through the collection of field data at a scale of 1:24,000. A large part of the map area consists of the Bronson Hill anticlinorium, a post-Early Devonian structure that is cored by metamorphosed Cambrian to Devonian sedimentary, volcanic, and plutonic rocks.The Bronson Hill anticlinorium is the apex of the Middle Ordovician to earliest-Silurian Bronson Hill magmatic arc that contains the Ammonoosuc Volcanics, Partridge Formation, and Oliverian Plutonic Suite, and extends from Maine, through western New Hampshire (down the eastern side of the Connecticut River), through southern New England to Long Island Sound. The deformed and partially eroded arc is locally overlain by a relatively thin Silurian section of metasedimentary rocks (Clough Quartzite and Fitch Formation) that thickens to the east. The Silurian section near Littleton is disconformably overlain by a thicker, Lower Devonian section that includes mostly metasedimentary and minor metavolcanic rocks of the Littleton Formation. The Bronson Hill anticlinorium is bisected by a series of northeast-southwest trending Mesozoic normal faults. Primarily among them is the steeply northwest-dipping Ammonoosuc fault that divides older and younger units (lower and upper sections) of the Ammonoosuc Volcanics. The Ammonoosuc Volcanics are lithologically complex and predominantly include interlayered and interfingered rhyolitic to basaltic volcanic and volcaniclastic rocks, as well as lesser amounts of slate, phyllite, ironstone, chert, sandstone, and pelite. The Albee Formation underlies the Ammonoosuc Volcanics and is predominantly composed of interbedded metamorphosed sandstone

The aims of the present study were therefore, to assess the markers of mental toughness (MT as a dimension of psychological functioning, sleep disturbances (SD, and PA among patients at the moment of disease onset and to compare these with the corresponding values for healthy adolescents and young adults. Methods: A total of 23 patients with MS at disease onset (mean age =32.31 years; 91% females, 23 healthy adolescents (mean age =17.43 years; 82% females, and 25 healthy young adults (mean age =20.72 years; 80% females took part in the study. They completed questionnaires covering sociodemographic data, MT, SD, and PA. Results: Patients with MS had similar scores for MT traits as those in healthy

The toxicity and bioavailability of chromium species are highly dependable on the form or species, therefore determination of total chromium is insufficient for a complete toxicological evaluation and risk assessment. An analytical method for determination of soluble and insoluble Cr (III) and Cr (VI) compounds in welding fume at workplace air has been developed. The total chromium (Cr) was determined by using quadruple inductively coupled plasma mass spectrometry (ICP-MS) equipped with a dynamic reaction cell (DRC(®)). Soluble trivalent and hexavalent chromium compounds were determined by high performance liquid chromatography with inductively coupled plasma mass spectrometry (HPLC-ICP-MS). A high-speed, reversed-phase CR C8 column (PerkinElmer, Inc., Shelton, CT, USA) was used for the speciation of soluble Cr (III) and soluble Cr (VI). The separation was accomplished by interaction of the chromium species with the different components of the mobile phase. Cr (III) formed a complex with EDTA, i.e. retained on the column, while Cr (VI) existed in the solutions as dichromate. Alkaline extraction (2% KOH and 3% Na2CO3) and anion exchange column (PRP-X100, PEEK, Hamilton) were used for the separation of the total Cr (VI). The results of the determination of Cr (VI) were confirmed by the analysis of the certified reference material BCR CRM 545 (Cr (VI) in welding dust). The results obtained for the certified material (40.2±0.6 g kg(-1)) and the values recorded in the examined samples (40.7±0.6 g kg(-1)) were highly consistent. This analytical method was applied for the determination of chromium in the samples in the workplace air collected onto glass (Whatman, Ø 37 mm) and membrane filters (Sartorius, 0.8 μm, Ø 37 mm). High performance liquid chromatography with inductively coupled plasma mass spectrometry is a remarkably powerful and versatile technique for determination of chromium species in welding fume at workplace air.

Full Text Available While many theories agree that the conceptual knowledge is organized in categories, there is less agreement on the underlying organizational principle (e.g. Warrington & Shallice, 1984, Caramazza & Shelton, 1998; Capitani et al., 2003. Previous neuropsychological studies on semantic categories failed to clearly characterize the status of food as a category as they did not carefully distinguish between natural food and transformed food. Exploring how natural food and transformed food items are processed in patients suffering from primary dementia can allow us to test the theories of how semantic knowledge is organized in the brain. Thirty patients and 15 healthy controls matched for age and education took part in the study . Thirteen patients received a presumptive diagnosis of fronto-temporal dementia (FTD, 3 patients of Semantic Dementia (SD, and 14 of Alzheimer Dementia (AD. All participants performed 3 tasks tapping lexical-semantic knowledge about food and non-food items: confrontation naming (Task 1, categorization (Task 2, and word-to-picture matching (Task 3. Moreover, half food items were natural (e.g., apple and half transformed (e.g. grana cheese, while non-food items were half non edible natural items (e.g., plant and half kitchen implements. The results showed that, overall, patients performed poorer than controls on Tasks 1 and 3, with FTD-SD patients being more impaired than AD patients. When we compared performance on food versus non-food items, we observed that patients performed better on naming food than non-food items (Task 1. Specifically, FTD-SD patients displayed a significant difference between food and non-food items, while AD patients showed no difference. On Task 3 the same pattern was obtained. In addition, we observed that, across tasks, transformed food was processed better than natural food. These findings suggest that lexical-semantic processes are more prone to degradation in patients FTD-SD than in AD patients

The bedrock geologic map of the Littleton and Lower Waterford quadrangles covers an area of approximately 107 square miles (277 square kilometers) north and south of the Connecticut River in east-central Vermont and adjacent New Hampshire. This map was created as part of a larger effort to produce a new bedrock geologic map of Vermont through the collection of field data at a scale of 1:24,000. A large part of the map area consists of the Bronson Hill anticlinorium, a post-Early Devonian structure that is cored by metamorphosed Cambrian to Devonian sedimentary, volcanic, and plutonic rocks. The northwestern part of the map is divided by the Monroe fault which separates Early Devonian rocks of the Connecticut Valley-Gaspé trough from rocks of the Bronson Hill anticlinorium.The Bronson Hill anticlinorium is the apex of the Middle Ordovician to earliest-Silurian Bronson Hill magmatic arc that contains the Ammonoosuc Volcanics, Partridge Formation, and Oliverian Plutonic suite, and extends from Maine, down the eastern side of the Connecticut River in New Hampshire, to Long Island Sound. The deformed and partially eroded arc is locally overlain by a relatively thin Silurian section of metasedimentary rocks (Clough Quartzite and Fitch Formation) that thickens to the east. The Silurian section near Littleton is disconformably overlain by a thicker, Lower Devonian section that includes mostly metasedimentary rocks and minor metavolcanic rocks of the Littleton Formation. The Bronson Hill anticlinorium is bisected by a series of northeast-southwest trending Mesozoic normal faults. Primarily among them is the steeply northwest-dipping Ammonoosuc fault that divides older and younger units (upper and lower sections) of the Ammonoosuc Volcanics. The Ammonoosuc Volcanics are lithologically complex and predominantly include interlayered and interfingered rhyolitic to basaltic volcanic and volcaniclastic rocks, as well as lesser amounts of metamorphic and metasedimentary rocks

Public acceptance is critical for sustaining nuclear power, and researchers have devised various methods to measure it (Stritar, 1996). Existing literatures suggest that rationality, emotion, knowledge of nuclear technology, trust, policy executor, and risk perception variables affect public acceptance. These attempts, however, have been limited to epistemological measurements using methods such as the Likert scale (Sjoberg and Drottz-Sjoberg, 2009; Slovic, 2000; Tanaka, 2004). Because such methods are standardized, it is difficult to reflect on emotions latent in individuals within the public. Moreover, surveys can be conducted only on people in a specific region and time interval, and it may be misleading to generalize the results to represent the attitude of the public. Because big data methods are based on unstructured data, which contain the live experiences/opinions, and are virtually real-time with almost no delay between the events of concern and the data collection, big data analysis allows real-time identification of relationships among different variables and their significance (Graham and Shelton, 2013). In this research, we propose big data analysis as a solution and attempt to identify the attitudes of the public on nuclear energy using big data analysis. To conclude, big data is a useful tool to measure the public acceptance of nuclear technology efficiently (i.e., saves cost, time, and effort of measurement and analysis), and this research was able to provide a case for using big data to analyze the public acceptance of nuclear technology. The trends and opinions of opinion leaders on SNSs should be monitored and responded to in real time. As demonstrated from the rejection of the extension of the Gori nuclear power plant, image and feeling are more important than the performance of the safety technology on the operation of a nuclear power plant. Because Korea has many aging reactors, evaluation of projects to extend the operation of old reactors

These therapies, however, increase risk of adverse bleeding events. We assessed patient-reported trade-offs between cardioprotective benefit, gastrointestinal bleeding risk, and burden of self-management using adaptive conjoint analysis (ACA. As ACA could be a clinically useful tool to obtain patient preferences and guide future patient-centered care, we examined the clinical application of ACA to obtain patient preferences and the impact of ACA on medication adherence.Patients and methods: An electronic ACA survey led 201 respondents through medication risk–benefit trade-offs, revealing patients’ preferences for the CAT risk/benefit profile they valued most. The post-ACA prescription regimen was categorized as concordant or discordant with elicited preferences. Adherence was measured using VA pharmacy refill data to measure persistence of use prior to and 1 year following preference-elicitation. Additionally, we analyzed qualitative interviews of 56 respondents

complex than that implied by traditional approaches. These lessons lead to the conclusion that technological change is far less automatic than that implied by simpler models, which presume fully informed and ''rational'' purchasers who are hypersensitive to marginal opportunities to save energy. The lessons also imply a set of policy guidelines with the potential to improve the attractiveness of energy-saving technologies to the marketplace. Numerous reviewers provided advice and guidance in preparing this paper. Jerry Dion suggested the topic and helped focus it to meet EERE needs. Marilyn Brown of Oak Ridge National Laboratory (ORNL) provided insightful comments on various drafts, as did Milton Russell of the Joint Institute for Energy and Environment (JIEE). Other colleagues at ORNL and JIEE, including but not limited to, Barbara Ashdown, Melissa Lapsa, Lee Grier, Robert Shelton, and Don Jones have also been supportive and have contributed useful comments and correction. A number of other colleagues contributed comments on earlier drafts. Naturally, the author retains full responsibility for any remaining shortcomings.

Groundwater provides more than 40 percent of California’s drinking water. To protect this vital resource, the State of California created the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The Priority Basin Project of the GAMA Program provides a comprehensive assessment of the State’s untreated groundwater quality and increases public access to groundwater-quality information. The Madera and Chowchilla subbasins of the San Joaquin Valley constitute one of the study units being evaluated. The Madera-Chowchilla study unit is about 860 square miles and consists of the Madera and Chowchilla groundwater subbasins of the San Joaquin Valley Basin (California Department of Water Resources, 2003; Shelton and others, 2009). The study unit has hot, dry summers and cool, moist winters. Average annual rainfall ranges from 11 to 15 inches, most of which occurs between November and February. The main surface-water features in the study unit are the San Joaquin, Fresno, and Chowchilla Rivers, and the Madera and Chowchilla canals. Land use in the study unit is about 69 percent (%) agricultural, 28% natural (mainly grasslands), and 3% urban. The primary crops are orchards and vineyards. The largest urban area is the city of Madera. The primary aquifer system is defined as those parts of the aquifer corresponding to the perforated intervals of wells listed in the California Department of Public Health (CDPH) database. In the Madera-Chowchilla study unit, these wells typically are drilled to depths between 200 and 800 feet, consist of a solid casing from land surface to a depth of about 140 to 400 feet, and are perforated below the solid casing. Water quality in the primary aquifer system may differ from that in the shallower and deeper parts of the aquifer system. The primary aquifer system in the study unit consists of Quaternary-age alluvial-fan and fluvial deposits that were formed by the rivers draining the Sierra Nevada. Sediments consist of gravels, sands

A content analysis of physical science textbooks with regard to the nature of science and ethnic diversity

Science.gov (United States)

Brooks, Kristine M.

The goal of science education is the preparation of scientifically literate students (Abd-El-Khalick & Lederman, 2000, & American Association for the Advancement of Science (AAAS), 1990). In order to instruct students in the nature of science with its history, development, methods and applications, science teachers use textbooks as the primary organizer for the curriculum (Chippetta, Ganesh, Lee, & Phillips, 2006). Science textbooks are the dominant instructional tool that exerts great influence on instructional content and its delivery (Wang, 1998). Science and science literacy requires acquiring knowledge about the natural world and understanding its application in society, or, in other words, the nature of science. An understanding of the nature of science is an important part of science literacy (Abd-El-Khalik & Lederman, 2000, & AAAS, 1990). The nature of science has four basic themes or dimensions: science as a body of knowledge, science as a way of thinking, science as a way of investigating, and science with its interaction with technology and society (Chippetta & Koballa, 2006). Textbooks must relay and incorporate these themes to promote science literacy. The results from this content analysis provide further insights into science textbooks and their content with regard to the inclusion of the nature of science and ethnic diversity. Science textbooks usually downplay human influences (Clough & Olson, 2004) whether as part of the nature of science with its historical development or its interaction with societies of diverse cultures. Minority students are underperforming in science and science is divided on ethnic, linguistic, and gender identity (Brown, 2005). Greater representations of diversity in curriculum materials enable minority students to identify with science (Nines, 2000). Textbooks, with their influence on curriculum and presentation, must include links for science and students of diverse cultures. What is the balance of the four aspects of the

Direct Investigations Of The Immobilization Of Radionuclides In The Alteration Phases Of Spent Nuclear Fuel

The safe disposal of the nation's nuclear waste in a geologic repository is one of the most significant and difficult scientific endeavors of the twenty-first century. Unique scientific challenges are posed by the very long-lived radioactivity of nuclear waste. Many radionuclides of vastly different chemical character must be retained by the repository for several thousand years. Some with longer half-lives, such as Pu-239 and Tc-99, need to be isolated for periods approaching a million years. In order to ensure the safety of a geologic repository, a detailed understanding of the mobility of radionuclides in complex natural systems is essential. Most of the radioactivity in a geological repository will be associated with spent nuclear fuel. In the United States spent fuel is derived from several sources. The majority is UO2 (LWR) spent fuel from commercial reactors. About 30,000 metric tons of spent fuel was in storage at commercial reactors by 1995, with the expectation that this quantity will more than double by 2010 (Integrated Data Report 1995). All spent fuel derived from commercial reactors is intended for eventual disposal in a geological repository. In addition, the DOE is the custodian of about 8000 metric tons of spent fuel, most of which is also intended for disposal in a geological repository. Although there are more than 250 types of spent fuel in the DOE inventory, the fuels may be broadly classified into (1) uranium metal fuel, (2) aluminum-based fuel, (3) mixed oxide (MOX) fuel containing substantial plutonium, and (4) graphite fuel (Colleen Shelton-Davis, personal communications, January 2000). Disposal of spent fuel in a geological repository requires detailed knowledge of the longterm behavior of the waste forms under repository conditions, as well as the fate of radionuclides released from the waste packages as containers are breached. The proposed Yucca Mountain repository is intended to hold 70,000 metric tons of high-level nuclear waste. Nine

Full Text Available Carrico, S.B., Cataldo, T.T., Botero, C., & Shelton, T. Objective – To compare e-book cost-usage data across different acquisitions styles and disciplines. Design – Case study. Setting – A public research university serving an annual enrollment of over 49,000 students and employing more than 3,000 faculty members in the Southern United States. Subjects – Cost and usage data from 15,006 e-books acquired by the Library through packages, firm orders, and demand-driven acquisitions. Methods – Data was collected from publishers and vendors across the three acquisitions strategies. Usage, cost, and call number information was collected for the materials purchased via firm order or demand driven acquisitions and these were sorted into disciplines based on the call number assigned. Discipline, cost, and use were determined for each package collection as a whole because information on individual titles was not provided by the publishers. The authors then compared usage and cost across disciplines and acquisitions strategies. Main Results – Overall, e-books purchased in packages had a 50% use rate and an average cost per use of $3.39, e-books purchased through firm orders had a 52% use rate and an average cost per use of $22.21, and e-books purchased through demand driven acquisitions had an average cost per use of $8.88 and 13.9 average uses per title. Package purchasing was cost effective for science, technology, engineering, and mathematics (STEM materials and medicine (MED materials. Demand driven acquisition was a particularly good strategy for humanities and social sciences (HSS titles. Conclusion – There are differences between the acquisitions strategies and disciplines in cost and use. Firm orders had a higher cost per use than the other acquisitions strategies. Commentary This study examined cost per use across three acquisitions styles and three disciplinary groups. The results agree with studies from other institutions that have

Looking back at 20 Years of Observations of this Supernova with ESO telescopes The unique supernova SN 1987A has been a bonanza for astrophysicists. It provided several observational 'firsts,' like the detection of neutrinos from an exploding star, the observation of the progenitor star on archival photographic plates, the signatures of a non-spherical explosion, the direct observation of the radioactive elements produced during the blast, observation of the formation of dust in the supernova, as well as the detection of circumstellar and interstellar material. ESO PR Photo 08a/07 ESO PR Photo 08a/07 SN1987A in the Large Magellanic Cloud Today, it is exactly twenty years since the explosion of Supernova 1987A in the Large Magellanic Cloud was first observed, at a distance of 163,000 light-years. It was the first naked-eye supernova to be seen for 383 years. Few events in modern astronomy have met with such an enthusiastic response by the scientists and now, after 20 years, it continues to be an extremely exciting object that is further studied by astronomers around the world, in particular using ESO's telescopes. When the first signs of Supernova 1987A, the first supernova of the year 1987, were noticed early on 24 February of that year, it was clear that this would be an unusual event. It was discovered by naked-eye and on a panoramic photographic plate taken with a 10-inch astrograph on Las Campanas in Chile by Oscar Duhalde and Ian Shelton, respectively. A few hours earlier, still on 23 February, two large underground detectors - in Japan and the USA - had registered the passage of high-energy neutrinos. Since SN 1987A exploded in the Large Magellanic Cloud (LMC), it was only accessible to telescopes in the Southern Hemisphere, more particularly in Australia, South Africa, and South America. In Chile, ESO's observatory at La Silla with its armada of telescopes with sizes between 0.5 and 3.6-m, played an important role. ESO PR Photo 08c/07 ESO PR Photo 08c/07 The
