Scarless genetic manipulation of genomes is an essential tool for biological research. The restriction-modification (R-M) system is a defense system in bacteria that protects against invading genomes on the basis of its ability to distinguish foreign DNA from self DNA. Here, we designed an R-M system-mediated genome editing (RMGE) technique for scarless genetic manipulation in different microorganisms. For bacteria with Type IV REase, an RMGE technique using the inducible DNA methyltransferase gene, bceSIIM (RMGE-bceSIIM), as the counter-selection cassette was developed to edit the genome of Escherichia coli. For bacteria without Type IV REase, an RMGE technique based on a restriction endonuclease (RMGE-mcrA) was established in Bacillus subtilis. These techniques were successfully used for gene deletion and replacement with nearly 100% counter-selection efficiencies, which were higher and more stable compared to conventional methods. Furthermore, precise point mutation without limiting sites was achieved in E. coli using RMGE-bceSIIM to introduce a single base mutation of A128C into the rpsL gene. In addition, the RMGE-mcrA technique was applied to delete the CAN1 gene in Saccharomyces cerevisiae DAY414 with 100% counter-selection efficiency. The effectiveness of the RMGE technique in E. coli, B. subtilis, and S. cerevisiae suggests the potential universal usefulness of this technique for microbial genome manipulation.

Nuclear measurements are used at AREVA NC/La Hague for the monitoring of spent fuel reprocessing. The process control is based on gamma-ray spectroscopy, passive neutron counting and active neutron interrogation, and gamma transmission measurements. The main objectives are criticality and safety, online process monitoring, and the determination of the residual fissile mass and activities in the metallic waste remained after fuel shearing and dissolution (empty hulls, grids, end pieces), which are put in radioactive waste drums before compaction. The whole monitoring system is composed of eight measurement stations which will be described in this paper. The main measurement stations no.more » 1, 3 and 7 are needed for criticality control. Before fuel element shearing for dissolution, station no. 1 allows determining the burn-up of the irradiated fuel by gamma-ray spectroscopy with HP Ge (high purity germanium) detectors. The burn-up is correlated to the {sup 137}Cs and {sup 134}Cs gamma emission rates. The fuel maximal mass which can be loaded in one bucket of the dissolver is estimated from the lowest burn-up fraction of the fuel element. Station no. 3 is dedicated to the control of the correct fuel dissolution, which is performed with a {sup 137}Cs gamma ray measurement with a HP Ge detector. Station no. 7 allows estimating the residual fissile mass in the drums filled with the metallic residues, especially in the hulls, from passive neutron counting (spontaneous fission and alpha-n reactions) and active interrogation (fission prompt neutrons induced by a pulsed neutron generator) with proportional {sup 3}He detectors. The measurement stations have been validated for the reprocessing of Uranium Oxide (UOX) fuels with a burn-up rate up to 60 GWd/t. This paper presents a brief overview of the current status of the nuclear measurement stations. (authors)« less

Area-based programmes are seen as a promising strategy for tackling health inequalities. In these programmes, local authorities and other local actors collaborate to employ health promoting interventions and policies. Little is known about the underlying processes of collaborative governance. To unravel this black box, we explored how the authority of The Hague, The Netherlands, developed a programme tackling health inequalities drawing on a collaborative mode of governance. Case study drawing on qualitative semi-structured interviews and document review. Data were inductively analysed against the concept of collaborative governance. The authority's ambition was to co-produce a programme on tackling health inequalities with local actors. Three stages could be distinguished in the governing process: (i) formulating policy objectives, (ii) translating policy objectives into interventions and (iii) executing health interventions. In the stage of formulating policy objectives, the collaboration led to a reframing of the initial objectives. Furthermore, the translation of the policy objectives into health interventions was rather pragmatic and loosely based on health needs and/or evidence. As a result, the concrete actions that ensued from the programme did not necessarily reflect the initial objectives. In a local system of health governance by collaboration, factors other than the stated policy objectives played a role, eventually undermining the effectiveness of the programme in reducing health inequalities. To be effective, the processes of collaborative governance underlying area-based programmes require the attention of the local authority, including the building and governing of networks, a competent public health workforce and supportive infrastructures.

Background In the Niayes area, located in the west of Senegal, only one tsetse species, Glossina palpalis gambiensis Vanderplank (Diptera: Glossinidae) was present. The Government of Senegal initiated and implemented an elimination programme in this area that included a sterile insect technique (SIT) component. The G. p. gambiensis strain (BKF) mass-reared at the Centre International de Recherche-Développement sur l'Elevage en zone Subhumide (CIRDES) in Burkina Faso was used for the SIT component. Methodology/principal findings Studies conducted in 2011 in four localities in the Niayes area (Pout, Sébikotane, Diacksao Peul and the Parc de Hann) showed that the BKF strain demonstrated inferior survival in the ecosystem of the Parc de Hann, a forested area in the city centre of the capital Dakar. Therefore, G. p. gambiensis flies from the Niayes area (SEN strain) were colonized. Here we compared the competitiveness and survival of the two strains (BKF and SEN) in the Parc de Hann. Released sterile males of the SEN colony showed a daily mortality rate of 0.08 (SD 0.08) as compared with 0.14 (SD 0.08) for the BKF flies but the difference was not significant (p-value = 0.14). However, the competitiveness of the SEN males was lower (0.14 (SD 0.10)) as compared with that of the BKF males (0.76 (SD 0.11)) (p-value < 10−3). Conclusions/significance Based on the results of this study, it can be concluded that the BKF strain will remain the main strain to be used in the elimination programme. Despite the slightly longer survival of the SEN males in the Parc de Hann, the superior competitiveness of the BKF males is deemed more important for the SIT component, as their shorter survival rates can be easily compensated for by more frequent fly releases.

A quantitative evaluation of the fate of (129)I, released from the European reprocessing plants of Sellafield (UK) and La Hague (France), has been made by means of a Lagrangian dispersion model. Transport of radionuclides to the Arctic Ocean has been determined. Thus, 5.1 and 16.6 TBq of (129)I have been introduced in the Arctic from Sellafield and La Hague respectively from 1966 to 2012. These figures represent, respectively, 48% and 55% of the cumulative discharge to that time. Inventories in the North Atlantic, including shelf seas, are 4.4 and 13.8 TBq coming from Sellafield and La Hague respectively. These figures are significantly different from previous estimations based on field data. The distribution of these inventories among several shelf seas and regions has been evaluated as well. Mean ages of tracers have been finally obtained, making use of the age-averaging hypothesis. It has been found that mean ages for Sellafield releases are about 3.5 year larger than for La Hague releases. Copyright © 2014 Elsevier Ltd. All rights reserved.

Generating acoustically bright and dark zones using loudspeakers is gaining attention as one of the most important acoustic communication techniques for such uses as personal sound systems and multilingual guide services. Although most conventional methods are based on numerical solutions, an analytical approach based on the spatial Fourier transform with a linear loudspeaker array has been proposed, and its effectiveness has been compared with conventional acoustic energy difference maximization and presented by computer simulations. To describe the effectiveness of the proposal in actual environments, this paper investigates the experimental validation of the proposed approach with rectangular and Hann windows and compared it with three conventional methods: simple delay-and-sum beamforming, contrast maximization, and least squares-based pressure matching using an actually implemented linear array of 64 loudspeakers in an anechoic chamber. The results of both the computer simulations and the actual experiments show that the proposed approach with a Hann window more accurately controlled the bright and dark zones than the conventional methods.

AREVA NC La Hague facility is the first step of the nuclear fuel recycling process implemented in France. The processing of the used fuel is governed by high standards of criticality-safety, and strong expectations on the quality of end-products. From the received used fuel assemblies, the plutonium and the uranium are extracted for further energy production purposes within the years following the reprocessing. Furthermore, the ultimate waste - fission products and minor actinides on the one hand, and hulls and end-pieces on the other hand - is adequately packaged for long term disposal. The used fuel is therefore separated into very different materials, and time scales which come into account may be longer than in some other nuclear fields of activity. Given the variety of the handled nuclear materials, as well as the time scales at stake, the importance given to some radionuclides, and hence to the associated nuclear data, can also be specific to the AREVA NC La Hague plant. A study has thus been led to identify a list of the most important radionuclides for the AREVA NC La Hague plant applications, relying on the running constraints of the facility, and the end-products expectations. The activities at the AREVA NC La Hague plant are presented, and the methodology to extract the most important radionuclides for the reprocessing process is detailed.

Evaluation of the effect of filter apodization for volume PET imaging using the 3-D RP algorithm

NASA Astrophysics Data System (ADS)

Baghaei, H.; Wong, Wai-Hoi; Li, Hongdi; Uribe, J.; Wang, Yu; Aykac, M.; Liu, Yaqiang; Xing, Tao

2003-02-01

We investigated the influence of filter apodization and cutoff frequency on the image quality of volume positron emission tomography (PET) imaging using the three-dimensional reprojection (3-D RP) algorithm. An important parameter in 3-D RP and other filtered backprojection algorithms is the choice of the filter window function. In this study, the Hann, Hamming, and Butterworth low-pass window functions were investigated. For each window, a range of cutoff frequencies was considered. Projection data were acquired by scanning a uniform cylindrical phantom, a cylindrical phantom containing four small lesion phantoms having diameters of 3, 4, 5, and 6 mm and the 3-D Hoffman brain phantom. All measurements were performed using the high-resolution PET camera developed at the M.D. Anderson Cancer Center (MDAPET), University of Texas, Houston, TX. This prototype camera, which is a multiring scanner with no septa, has an intrinsic transaxial resolution of 2.8 mm. The evaluation was performed by computing the noise level in the reconstructed images of the uniform phantom and the contrast recovery of the 6-mm hot lesion in a warm background and also by visually inspecting images, especially those of the Hoffman brain phantom. For this work, we mainly studied the central slices which are less affected by the incompleteness of the 3-D data. Overall, the Butterworth window offered a better contrast-noise performance over the Hann and Hamming windows. For our high statistics data, for the Hann and Hamming apodization functions a cutoff frequency of 0.6-0.8 of the Nyquist frequency resulted in a reasonable compromise between the contrast recovery and noise level and for the Butterworth window a cutoff frequency of 0.4-0.6 of the Nyquist frequency was a reasonable choice. For the low statistics data, use of lower cutoff frequencies was more appropriate.

INTRODUCTION: Award of the 2004 Hannes Alfvén Prize of the European Physical Society to J W Connor, R J Hastie and J B Taylor

NASA Astrophysics Data System (ADS)

Lister, Jo, Dr

2004-12-01

Jack Connor, Jim Hastie and Bryan Taylor The Hannes Alfvén Prize of the European Physical Society for Outstanding Contributions to Plasma Physics (2004) has been awarded to Jack Connor, Jim Hastie and Bryan Taylor `for their seminal contributions to a wide range of issues of fundamental importance to the success of magnetic confinement fusion, including: the development of gyro-kinetic theory; the prediction of the bootstrap current; dimensionless scaling laws; pressure-limiting instabilities, and micro-stability and transport theory'. Jack Connor, Jim Hastie and Bryan Taylor form one of the most successful teams of theoretical physicists in the history of magnetic confinement fusion. They have made important contributions individually, but their greatest discoveries have mostly been accomplished jointly, either in pairs or as a team involving all three. Their early work, in the 1960s, included the development of the gyro-kinetic theory for fine-scale plasma instabilities, which today forms the basis of the most advanced turbulence simulation codes in tokamak and stellarator research. The theoretical prediction of the bootstrap current, made in 1970-71 was not confirmed experimentally for over a decade but is now regarded as crucial to the success of the tokamak as a steady-state fusion power source. Their work on collisional transport also included the prediction of impurity ion accumulation, which is observed in internal transport barriers and is a key concern for long-pulse tokamak operation. The relativistic threshold for runaway electrons, identified in 1975, forms the basis of the most recent tokamak disruption mitigation schemes. In the late 1970s, the team developed the theory for ballooning instabilities, which provided an important ingredient in the `Troyon-Sykes' β-limit—an expression that is still used as a guide to the performance of tokamaks and in the design of ITER. Ballooning mode theory has also contributed to the understanding of

When Yang-Hann Kim received the Rossing Prize in Acoustics Education at the 2015 meeting of the Acoustical Society of America, he stressed the importance of offering visual depictions of sound fields when teaching acoustics. Often visualization methods require specialized equipment such as microphone arrays or scanning apparatus. We present a simple method for visualizing angular dependence in sound fields, made possible via the confluence of sensors available via a new smartphone app that the authors have developed.

Since the 1994 International Conference on Population and Development (ICPD), the Philippine government has worked closely with nongovernmental and peoples' organizations to push reforms which promote development which is broad-based, sustainable, and focused upon human resources. These initiatives recognized the important role of population and human development, and try to achieve rapid economic growth while protecting the environment. The government worked closely with civil society to draft a medium-term development plan for 1993-98 to improve the quality of life for all Filipinos. Reproductive health will be an important component of the Medium-Term Philippine Development Plan for 1999-2004. However, the necessary resources must be mobilized to carry out all elements of the program of action. Since the ICPD, total funding for reproductive health and family planning reached Philippine P 1 billion, of which 58% was provided by the foreign donor community. So far, the Philippine government has been blocked by the Catholic Church from allocating more public funds for contraception. Local government units need to take a more direct and active role in implementing rural health programs in general and reproductive health programs in particular.

Our Dynamic Sun (Hannes Alfvén Medal Lecture)

NASA Astrophysics Data System (ADS)

Priest, Eric

2017-04-01

The Sun, an object of worship for early civilisations, is the main source of light and life on Earth and of our space weather, with many subtle effects on our environment. The lecture will introduce you to the Sun and its dynamic phenomena, and will aim to show how our understanding of many aspects of the Sun has been revolutionized over the past few years by current spacecraft observations and models. Much of the dynamic behaviour is driven by the magnetic field since, in the outer atmosphere (or corona), it represents by far the largest source of energy. The interior of the Sun, revealed by solar seismology, possesses a strong shear layer at the base of the convection zone, where sunspot magnetic fields are generated. But a small-scale dynamo is also operating near the surface of the Sun, generating magnetic fields that thread the lowest layer of the solar atmosphere, the photosphere, in a turbulent convective state. Above the photosphere lies the highly dynamic fine-scale chromosphere and beyond that the rare corona at high temperatures exceeding one million degrees K. Magnetic mechanisms for heating the corona (an intriguing puzzle) will be described. Other puzzles include the structure of giant flux ropes, known as prominences, which have complex fine structure. Occasionally, they erupt and produce huge ejections of mass and magnetic field (coronal mass ejections), which can disrupt the space environment of the Earth. When such eruptions originate in active regions around sunspots, they are also associated with solar flares, where magnetic energy is converted to kinetic, heat and fast particle energy. A new theory will be presented for the origin of the twist that is observed in erupting prominences.

2016-10-01

Enterprise imaging governance is an emerging need in health enterprises today. This white paper highlights the decision-making body, framework, and process for optimal enterprise imaging governance inclusive of five areas of focus: program governance, technology governance, information governance, clinical governance, and financial governance. It outlines relevant parallels and differences when forming or optimizing imaging governance as compared with other established broad horizontal governance groups, such as for the electronic health record. It is intended for CMIOs and health informatics leaders looking to grow and govern a program to optimally capture, store, index, distribute, view, exchange, and analyze the images of their enterprise.

In 1922 Hanns Walter Kornblum produced a long and comprehensive educational film on Albert Einstein’s theory of relativity that made extensive use of trick shots. His film was considered to be a milestone in the history of film and also in the popularization of science. Although the original film has been lost, I have reconstructed its content and its reception by members of the German film industry and cultural sector, laymen, scientists and academics, and politically motivated opponents based upon the large collection of newspaper clippings that was assembled by the antirelativist physicist Ernst Gehrcke.

A prolific and inventive painter, draftsman, and poet, Adriaen Pietersz van de Venne was born in Delft in 1589. His wealthy parents had fled from Protestant persecution in the Southern (Spanish) Netherlands during the 1580s. Van de Venne was educated in Leiden, where he became part of the vibrant political and intellectual community around the University. He settled in Middleburg, in Zeeland, by 1614; his earliest dated paintings are also from this year. In 1625, van de Venne moved to The Hague, where he remained until his dealth. He executed several commissions for the Dutch stadholder Frederik Hendrik, was repeatedly elected dean of the guild of St. Luke, and in 1656 was one of the founding members of The Hague's painter's guild, "Pictura schilders confrerie." Van de Venne painted histories, portraits, and genre scenes; from 1618, he was also active as a printmaker and book illustrator, notably for the popular poet Jacob Cats. His literary accomplishments included satire and political propaganda, as well as several books of poetry. Copyright American Academy of the History of Dentistry.

Care providers today routinely obtain valuable clinical multimedia with mobile devices, scope cameras, ultrasound, and many other modalities at the point of care. Image capture and storage workflows may be heterogeneous across an enterprise, and as a result, they often are not well incorporated in the electronic health record. Enterprise Imaging refers to a set of strategies, initiatives, and workflows implemented across a healthcare enterprise to consistently and optimally capture, index, manage, store, distribute, view, exchange, and analyze all clinical imaging and multimedia content to enhance the electronic health record. This paper is intended to introduce Enterprise Imaging as an important initiative to clinical and informatics leadership, and outline its key elements of governance, strategy, infrastructure, common multimedia content, acquisition workflows, enterprise image viewers, and image exchange services.

This white paper explores the technical challenges and solutions for acquiring (capturing) and managing enterprise images, particularly those involving visible light applications. The types of acquisition devices used for various general-purpose photography and specialized applications including dermatology, endoscopy, and anatomic pathology are reviewed. The formats and standards used, and the associated metadata requirements and communication protocols for transfer and workflow are considered. Particular emphasis is placed on the importance of metadata capture in both order- and encounter-based workflow. The benefits of using DICOM to provide a standard means of recording and accessing both metadata and image and video data are considered, as is the role of IHE and FHIR.

There is increasing competition among the main Western European airports, and smaller, regional airports are fighting for market share. New modes of transport, such as high speed rail, arc also coming into the picture and affect the mode split for medium distance transport within Europe. Developments such as these are demanding the attention of policy makers and a tool is required for their analysis. For DGCA, Hague Consulting Group has developed a model system to provide answers to the policy questions posed by these expected trends, and to identify areas where policy makers can influence the traveller choices. The development of this model system, the Integrated Airport Competition Model/Integral Luchthaven Competitive Model (ILCM), began in 1992. Since that time the sub-models, input data and user interface have been expanded, updated and improved. HCG and DGCA have transformed the ILCM from a prototype into an operational forecasting tool.

UP2 400 High Activity Oxide Legacy Waste Retrieval Project Scope and Progress-13048

DOE Office of Scientific and Technical Information (OSTI.GOV)

Chabeuf, Jean-Michel; Varet, Thierry

The High Activity Oxide facility (HAO) reprocessed sheared and dissolved 4500 metric tons of light water reactor fuel the fuel of the emerging light water reactor spent fuel between 1976 and 1998. Over the period, approximately 2200 tons of process waste, composed primarily of sheared hulls, was produced and stored in a vast silo in the first place, and in canisters stored in pools in subsequent years. Upon shutdown of the facility, AREVA D and D Division in La Hague launched a thorough investigation and characterization of the silos and pools content, which then served as input data for themore » definition of a legacy waste retrieval and reconditioning program. Basic design was conducted between 2005 and 2007, and was followed by an optimization phase which lead to the definition of a final scenario and budget, 12% under the initial estimates. The scenario planned for the construction of a retrieval and reconditioning cell to be built on top of the storage silo. The retrieved waste would then be rinsed and sorted, so that hulls could subsequently be sent to La Hague high activity compacting facility, while resins and sludge would be cemented within the retrieval cell. Detailed design was conducted successfully from 2008 until 2011, while a thorough research and development program was conducted in order to qualify each stage of the retrieval and reconditioning process, and assist in the elaboration of the final waste package specification. This R and D program was defined and conducted as a response and mitigation of the major project risks identified during the basic design process. Procurement and site preparatory works were then launched in 2011. By the end of 2012, R and D is nearly completed, the retrieval and reconditioning process have been secured, the final waste package specification is being completed, the first equipment for the retrieval cell is being delivered on site, while preparation works are allowing to free up space above and around the silo

CESAR: A Code for Nuclear Fuel and Waste Characterisation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Vidal, J.M.; Grouiller, J.P.; Launay, A.

2006-07-01

CESAR (Simplified Evolution Code Applied to Reprocessing) is a depletion code developed through a joint program between CEA and COGEMA. In the late 1980's, the first use of this code dealt with nuclear measurement at the Laboratories of the La Hague reprocessing plant. The use of CESAR was then extended to characterizations of all entrance materials and for characterisation, via tracer, of all produced waste. The code can distinguish more than 100 heavy nuclides, 200 fission products and 100 activation products, and it can characterise both the fuel and the structural material of the fuel. CESAR can also make depletionmore » calculations from 3 months to 1 million years of cooling time. Between 2003-2005, the 5. version of the code was developed. The modifications were related to the harmonisation of the code's nuclear data with the JEF2.2 nuclear data file. This paper describes the code and explains the extensive use of this code at the La Hague reprocessing plant and also for prospective studies. The second part focuses on the modifications of the latest version, and describes the application field and the qualification of the code. Many companies and the IAEA use CESAR today. CESAR offers a Graphical User Interface, which is very user-friendly. (authors)« less

La Hague facility, in France, is the spent fuel recycling plant wherein a part of the fuel coming from some of the French, German, Belgian, Swiss, Dutch and Japanese nuclear reactors is reprocessed before being recycled in order to separate certain radioactive elements. The facility has been successively handled by the CEA (1962-1978), Cogema (1978-2006), and AREVA NC (since 2006). La Hague facility is composed of 3 production units: The UP2-400 production unit started to be operated in 1966 for the reprocessing of UNGG metal fuel. In 1976, following the dropout of the graphite-gas technology by EDF, an HAO workshopmore » to reprocess the fuel from the light water reactors is affiliated and then stopped in 2003. - UP2-400 is partially stopped in 2002 and then definitely the 1 January 2004 and is being dismantled - UP2-800, with the same capacity than UP3, started to be operated in 1994 and is still in operation. And UP3 - UP3 was implemented in 1990 with an annual reprocessing capacity of 800 tons of fuel and is still in operation The combined licensed capacity of UP2-800 and UP3 is 1,700 tons of used fuel.

They were two sisters, living in The Hague/Leiden, who came from a rich banker's family, the van der Lindens. Whereas the treatment does not seem to have led to any decisive improvement for the older of the two, it may have encouraged the younger sister to seek divorce.

The aim of this work is to study the citric acid fermentation by a robust strain Aspergillus niger SIIM M288 using corn stover feedstock after dry dilute sulfuric acid pretreatment and biodetoxification. Citric acid at 100.04g/L with the yield of 94.11% was obtained, which are comparable to the starch or sucrose based citric acid fermentation. No free wastewater was generated in the overall process from the pretreatment to citric acid fermentation. Abundant divalent metal ions as well as high titer of potassium, phosphate, and nitrogen were found in corn stover hydrolysate. Further addition of extra nutrients showed no impact on increasing citric acid formation except minimum nitrogen source was required. Various fermentation parameters were tested and only minimum regulation was required during the fermentation. This study provided a biorefining process for citric acid fermentation from lignocellulose feedstock with the maximum citric acid titer and yield. Copyright © 2016 Elsevier Ltd. All rights reserved.

Langer, Steve G

2017-02-01

In 1999-2003, SIIM (then SCAR) sponsored the creation of several special topic Primers, one of which was concerned with computer security. About the same time, a multi-society collaboration authored an ACR Guideline with a similar plot; the latter has recently been updated. The motivation for these efforts was the launch of Health Information Portability and Accountability Act (HIPAA). That legislation directed care providers to enable the portability of patient medical records across authorized medical centers, while simultaneously protecting patient confidentiality among unauthorized agents. These policy requirements resulted in the creation of numerous technical solutions which the above documents described. While the mathematical concepts and algorithms in those papers are as valid today as they were then, recent increases in the complexity of computer criminal applications (and defensive countermeasures) and the pervasiveness of Internet connected devices have raised the bar. This work examines how a medical center can adapt to these evolving threats.

Alfvén Waves and the Aurora (Hannes Alfvén Medal Lecture)

NASA Astrophysics Data System (ADS)

Lysak, Robert

2015-04-01

The most compelling visual evidence of plasma processes in the magnetosphere of Earth as well as the other magnetized planets is the aurora. Over 40 years of research have indicated that the aurora is a consequence of the acceleration of charged particles toward the neutral atmosphere, where the excitation of neutral atoms and their subsequent relaxation to the ground state produces the auroral light. Much of this acceleration can be described by acceleration in a quasi-static electric field parallel to the geomagnetic field, producing nearly monoenergetic beams of electrons. While a variety of quasi-static models to describe such parallel electric fields have been developed, the dynamics of how these fields evolve is still an open question. Satellite measurements have indicated that a primary source of energy to support these fields is the Poynting flux associated with shear Alfvén waves propagating along auroral field lines. These Alfvén waves are generated in the magnetosphere and reflect from the ionosphere. On closed field lines, Alfvén waves bouncing between conjugate ionospheres produce field line resonances that have be observed both in space and by ground magnetometers. However, some auroral emissions do not follow this scenario. In these cases, the accelerated electrons are observed to have a broad energy spectrum, rather than a monoenergetic peak. Such a spectrum is suggestive of a time-dependent acceleration process that operates on a time scale of a few seconds, comparable to the electron transit time across the acceleration region. While field line resonances have a time scale on the order of minutes, waves with periods of a few seconds can be produced by partial reflections in the Ionospheric Alfvén Resonator, a resonant cavity formed by the rapid decrease of the plasma density and increase of the Alfvén speed above the ionosphere. In order to develop a parallel electric field that can accelerate auroral particles, these Alfvén waves must develop small spatial scales, where MHD theory breaks down. In this regime, the waves are called kinetic Alfvén waves. These small scales can be produced most simply be phase mixing, although ionospheric feedback and nonlinear effects may also be important. Since kinetic Alfvén waves require perpendicular wavelengths the order of a few kilometers, this model also provides a natural explanation of the narrow scales of discrete auroral arcs. These interactions between magnetosphere and ionosphere and the development of parallel electric fields have been described by means of numerical simulations that serve to illustrate these complex processes.

CEA and AREVA-NC have developed and used a depletion code named CESAR for 30 years. This user-friendly industrial tool provides fast characterizations for all types of nuclear fuel (PWR / UOX or MOX or reprocess Uranium, BWR / UOX or MOX, MTR and SFR) and the wastes associated. CESAR can evaluate 100 heavy nuclides, 200 fission products and 150 activation products (with Helium and Tritium formation). It can also characterize the structural material of the fuel (Zircalloy, stainless steel, M5 alloy). CESAR provides depletion calculations for any reactor irradiation history and from 3 months to 1 million years of coolingmore » time. CESAR5.3 is based on the latest calculation schemes recommended by the CEA and on an international nuclear data base (JEFF-3.1.1). It is constantly checked against the CEA referenced and qualified depletion code DARWIN. CESAR incorporates the CEA qualification based on the dissolution analyses of fuel rod samples and the 'La Hague' reprocessing plant feedback experience. AREVA-NC uses CESAR intensively at 'La Hague' plant, not only for prospective studies but also for characterizations at different industrial facilities all along the reprocessing process and waste conditioning (near 150 000 calculations per year). CESAR is the reference code for AREVA-NC. CESAR is used directly or indirectly with other software, data bank or special equipment in many parts of the La Hague plants. The great flexibility of CESAR has rapidly interested other projects. CESAR became a 'tool' directly integrated in some other softwares. Finally, coupled with a Graphical User Interface, it can be easily used independently, responding to many needs for prospective studies as a support for nuclear facilities or transport. An English version is available. For the principal isotopes of U and Pu, CESAR5 benefits from the CEA experimental validation for the PWR UOX fuels, up to a burnup of 60 GWd/t and for PWR MOX fuels, up to 45 GWd/t. CESAR version 5.3 uses the

We report a case of lip repair surgery performed for bilateral cleft lip and palate in a patient diagnosed with trisomy 13 and holoprosencephaly. At the age of 2 years and 7 months, the surgery was performed using a modified De Hann design under general anesthesia. The operation was completed in 1 h and 21 min without large fluctuations in the child's general condition. The precise measurement of the intraoperative design was omitted, and the operation was completed using minimal skin sutures. It is possible to perform less-invasive and short surgical procedures after careful consideration during the preoperative planning. Considering the recent improvements in the life expectancy of patients with trisomy 13, we conclude that surgical treatments for non-life threatening malformations such as cleft lip and palate should be performed for such patients.

2016-01-01

The presented paper compares forecast of drought indices based on two different models of artificial neural networks. The first model is based on feedforward multilayer perceptron, sANN, and the second one is the integrated neural network model, hANN. The analyzed drought indices are the standardized precipitation index (SPI) and the standardized precipitation evaporation index (SPEI) and were derived for the period of 1948-2002 on two US catchments. The meteorological and hydrological data were obtained from MOPEX experiment. The training of both neural network models was made by the adaptive version of differential evolution, JADE. The comparison of models was based on six model performance measures. The results of drought indices forecast, explained by the values of four model performance indices, show that the integrated neural network model was superior to the feedforward multilayer perceptron with one hidden layer of neurons.

The disposal of radioactive wastes in the sea (case of the La Hague site) is favored by the physical dispersion and transport of the effluents by marine currents. Concentration and precipitation phenomena can inhibit the dispersion. Research has been effected on the way in which the fixing of pollutants occurs and the degree to which it occurs. Investigations were then carried out on the utilization of the marine environment by man (foodstuffs from the sea, distribution of such products, alimentation, critical population groups). (FR)

The climate treaty being hammered out this month at The Hague may be doomed to failure, as numerous observers say the United States simply won't ratify any treaty that requires such wrenching reductions in carbon emissions, and if the United States bails out, the protocol is in very deep trouble. Some policy analysts think that by tweaking the rules, the United States could eventually sign on, but if they are tweaked too much, other countries may balk. The key, some say, will be keeping the treaty going now and rethinking its controversial goals later.

Freud and film: encounters in the Weltgeist.

PubMed

Sklarew, B

1999-01-01

Freud's antipathy toward film is striking, since film and dreams are formed by similar mechanisms. Nevertheless, Freud occasionally and unavoidably encountered film. This paper details some of these encounters. Ten years after viewing time-lapse photography, a fore-runner of moving pictures, at the Salpêtrière, he was conceptualizing a model of the mind and of the formation of dreams that in some ways parallels the film apparatus invented by the Lumière brothers in December 1895. On his visit to America in 1905, Freud saw movies in New York City. In 1925, he refused a lucrative offer to consult on a film, and he discouraged Karl Abraham and Hanns Sachs from consulting on the first psychoanalytic film, Pabst's Secrets of a Soul (1926). He was, however, once sighted viewing an American double feature in Vienna. The paper closes with a critique of his acting in home movies.

Discrimination and the incidence of psychotic disorders among ethnic minorities in The Netherlands.

It is well established now that the incidence of schizophrenia is extremely high for several ethnic minority groups in western Europe, but there is considerable variation among groups. We investigated whether the increased risk among these groups depends upon the degree to which they perceive discrimination based on race or ethnicity. We studied the incidence of psychotic disorders over 7 years in The Hague, a city with a large and diverse population of ethnic minorities. To compare the incidence of schizophrenic disorders (DSM IV: schizophrenia, schizophreniform disorder, schizoaffective disorder) in each ethnic minority group with the incidence in native Dutch, we computed incidence rate ratios (IRRs). Based on a population study and on rates of reported incidents of discrimination in The Hague, the degree of perceived discrimination of ethnic minority groups was rated: high (Morocco), medium (Netherlands-Antilles, Surinam and 'other non-western countries'), low (Turkey) or very low ('western or westernized countries'). The age- and gender-adjusted IRRs of schizophrenic disorders for ethnic minority groups exposed to high, medium, low, and very low discrimination were 4.00 (95% CI 3.00-5.35), 1.99 (1.58-2.51), 1.58 (1.10-2.27), and 1.20 (0.81-1.90), respectively. When not only schizophrenic, but all psychotic disorders were included in the analysis, the results were similar. These results suggest that discrimination perceived by ethnic minority groups in western Europe, or some factor closely related to it, may contribute to their increased risk of schizophrenia.

Comparing policies for children of parents attending hospital emergency departments after intimate partner violence, substance abuse or suicide attempt.

To improve identification of child maltreatment, a new policy ('Hague protocol') was implemented in hospitals in The Netherlands, stating that adults attending the hospital emergency department after intimate partner violence, substance abuse or a suicide attempt should be asked whether they care for children. If so, these children are referred to the Reporting Center for Child Abuse and Neglect (RCCAN), for assessment and referrals to support services. An adapted, hospital-based version of this protocol ('Amsterdam protocol') was implemented in another region. Children are identified in the same manner, but, instead of a RCCAN referral, they are referred to the pediatric outpatient department for an assessment, including a physical examination, and referrals to services. We compared results of both protocols to assess how differences between the protocols affect the outcomes on implementation, detection of child maltreatment and referrals to services. Furthermore, we assessed social validity and results of a screening physical examination. We included 212 families from the Amsterdam protocol (cohort study with reports by pediatric staff and parents) and 565 families from the Hague protocol (study of RCCAN records and telephone interviews with parents). We found that the RCCAN identified more maltreatment than pediatric staff (98% versus at least 51%), but referrals to services were similar (82% versus 80% of the total sample) and parents were positive about both interventions. Physical examination revealed signs of maltreatment in 5%. We conclude that, despite the differences, both procedures can serve as suitable methods to identify and refer children at risk for maltreatment. Copyright © 2015 Elsevier Ltd. All rights reserved.

Difficult-to-treat epilepsies and attention-deficit-hyperactivity disorder (ADHD) often co-occur. Because of concerns about the use of stimulants in children with this comorbidity, the impact of ADHD treatment on seizure frequency and severity is not known. This pilot study evaluated the safety and efficacy of methylphenidate in this population. After a 3 month period in which antiepileptic drugs were adjusted, 22 patients recruited from a specialist outpatient clinic for severe epilepsy (16 males, six females; mean age 11 y 2 mo, SD 3 y 2 mo) received methylphenidate for 3 months in an open label, non-controlled trial; four with generalized or multifocal (symptomatic/cryptogenic) epilepsy, one with generalized (idiopathic) epilepsy, 17 with partial (symptomatic/cryptogenic) epilepsy; five with partial seizures only, 17 with primarily or secondarily generalized seizures). Epilepsy, ADHD symptoms, and side effects were assessed using the Swanson, Nolan, and Pelham Questionnaire, the Child Behavior Checklist, the Hague Seizure Severity Scale, and the Side Effects Rating Scale. Methylphenidate significantly improved ADHD. After 3 months of treatment, 73% of patients no longer had clinically significant symptoms. Methylphenidate also reduced seizure severity (9-point median decrease on the Hague Seizure Severity Scale). Seizure frequency increased in four out of 22 patients, but only one patient withdrew from the study for this reason. Most patients experienced no major side effects. These data are among the first showing that low doses of methylphenidate are safe and effective to treat ADHD symptoms in patients with difficult-to-treat epilepsies. Randomized controlled trials are needed to replicate the findings. © The Authors. Developmental Medicine & Child Neurology © 2013 Mac Keith Press.

Protection of Cultural Heritage in Urban Areas during Peace and Conflict Times from Threats to Risk Preparedness as a Shared Responsibility

2013-07-01

In times of economic hardship, the support given by specialized civil society organisations to public institutions in the protection of cultural heritage has often proved very useful, and there is evidence that their contribution is essential in times of conflicts and natural disasters, if well-designed plans and measures are organized efficiently, thoroughly tested and properly implemented. The 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict (HC), its two Protocols and other international juridical instruments address these situations since decades, however, they remained widely not-applied in absence of proper regulatory instruments. In 2004, the Second Protocol of the Hague Convention (1999HP) entered into force and the Committee of the State Parties was formed. It became clear that a new trend started when, in 2009, draft Guidelines for the implementation of the 1999HP were issued. Meanwhile, WATCH, in partnership with the Council of the United Municipalitities of Jbail (Lebanon) and the Head of the Municipality of Mtskheta (Georgia) prepared a project proposal aimed to set a precedent in the governance of urban sites that are registered in the World Heritage List which are at risk of armed conflict. The project War Free World Heritage Listed Cities http://www.warfreeheritage.net/ was co-financed in 2010 with a grant within the framework of the EC CIUDAD programme and it is currently at an advanced level of implementation. This presentation will focus on achievements and contingencies faced during implementation as well as lessons learned that could be surely useful for pers pective applicants.

Experiences of citizen-based reporting of rainfall events using lab-generated videos

NASA Astrophysics Data System (ADS)

Alfonso, Leonardo; Chacon, Juan

2016-04-01

Hydrologic studies rely on the availability of good-quality precipitation estimates. However, in remote areas of the world and particularly in developing countries, ground-based measurement networks are either sparse or nonexistent. This creates difficulties in the estimation of precipitation, which limits the development of hydrologic forecasting and early warning systems for these regions. The EC-FP7 WeSenseIt project aims at exploring the involvement of citizens in the observation of the water cycle with innovative sensor technologies, including mobile telephony. In particular, the project explores the use of a smartphone applications to facilitate the reporting water-related situations. Apart from the challenge of using such information for scientific purposes, the citizen engagement is one of the most important issues to address. To this end effortless methods for reporting need to be developed in order to involve as many people as possible in these experiments. A potential solution to overcome these drawbacks, consisting on lab-controlled rainfall videos have been produced to help mapping the extent and distribution of rainfall fields with minimum effort [1]. In addition, the quality of the collected rainfall information has also been studied [2] by means of different experiments with students. The present research shows the latest results of the application of this method and evaluates the experiences in some cases. [1] Alfonso, L., J. Chacón, and G.

75th Anniversary of `Existence of Electromagnetic-Hydrodynamic Waves'

NASA Astrophysics Data System (ADS)

Russell, Alexander J. B.

2018-05-01

We have recently passed the 75th anniversary of one of the most important results in solar and space physics: Hannes Alfvén's discovery of Alfvén waves and the Alfvén speed. To celebrate the anniversary, this article recounts some major episodes in the history of magnetohydrodynamic (MHD) waves. Following an initially cool reception, Alfvén's ideas were propelled into the spotlight by Fermi's work on cosmic rays, the new mystery of coronal heating, and, as scientific perception of interplanetary space shifted dramatically and the space race started, detection of Alfvén waves in the solar wind. From then on, interest in MHD waves boomed, laying the foundations for modern remote observations of MHD waves in the Sun, coronal seismology, and some of today's leading theories of coronal heating and solar wind acceleration. In 1970, Alfvén received the Nobel Prize for his work in MHD, including these discoveries. The article concludes with some reflection about what the history implies about the way we do science, especially the advantages and pitfalls of idealised mathematical models.

Claims about the health risks posed by nuclear-power installations are always controversial, but nowhere more so than in France, where some 75% of the nation`s electricity is generated from nuclear energy. So, it was no surprise that publication of a study by two French epidemiologists earlier this month claiming to show a link between cases of childhood leukemia and the nuclear-waste reprocessing plant at La Hague on the Normandy coast sparked fireworks in the French press. Several French epidemiologists sharply criticized the study`s methodology and conclusions.

Radar probing of ionospheric plasmas precisely confirms linear kinetic plasma theory (Hannes Alfvén Medal Lecture)

NASA Astrophysics Data System (ADS)

Farley, Donald

2010-05-01

In 1958 W. E. Gordon first suggested that huge radars could probe the ionosphere via scattering from independent electrons, even though the radar cross section of a single electron is only 10-28 m2. This suggestion quickly led to the construction of two enormous radars in the early 1960s, one near Lima, Peru, and one near Arecibo, Puerto Rico. It soon became apparent that the theory of this scatter was more complicated than originally envisaged by Gordon. Although the new theory was more complicated, it was much richer: by measuring the detailed shape of the Doppler frequency spectrum (or alternatively the signal autocorrelation function, the ACF), a radar researcher could determine many, if not most, of the parameters of interest of the plasma. There is now a substantial network of major radar facilities scattered from the magnetic equator (Peru) to the high arctic latitudes (Svalbard and Resolute Bay), all doing important ionospheric research. The history of what is now called Incoherent Scatter (even though it is not truly incoherent) is fascinating, and I will touch on a few highlights. The sophisticated radar and data processing techniques that have been developed are also impressive. In this talk, however, I want to focus mainly on the details of the theory and on how the radar observations have confirmed the predictions of classical linear plasma kinetic theory to an amazingly high degree of precision, far higher than has any other technique that I am aware of. The theory can be, and has been, developed from two very different points of view. One starts with 'dressed particles,' or Coulomb 'clouds' around ions and electrons moving with a Maxwellian velocity distribution; the second starts by considering all the charged particles to be made up of a spectrum of density plane waves and then invokes a generalized version of the Nyquist Noise Theorem to calculate the thermal amplitudes of the waves. Both approaches give exactly the same results, results that allow us to predict exactly the scattered power and Doppler spectrum for any given set of plasma parameters (e.g., electron and ion temperatures, ionic composition, mean drifts and currents, the geomagnetic field, and particle collisions). So far, these predictions have not failed, although in recent years we have had to resort to numerical simulations to do a proper calculation of electron Coulomb collisions when the radar beam is pointed very nearly perpendicular to the magnetic field. This is because no analytic way has yet been found to properly apply the Fokker-Planck Coulomb collision model to the scattering process. Of course the theory predicts the spectrum, given all the plasma parameters, when what we really want to do in ionospheric research is the inverse, namely find the parameters, given the radar data. This inverse process can be quite difficult to do optimally if there are too many unknown parameters. Statistical inverse theory can require enormous computing power, but progress is being made.

Worlds and Anti-worlds Revisted

NASA Astrophysics Data System (ADS)

Wolff, Milo

1996-05-01

In =D2Worlds and Anti-worlds=D3 (1960) Hannes Alfven=20 described a universe symmetric in matter and anti-matter. Today we cannot decide if galaxies and anti-galaxies exist because radiation from both=20 is alike. If matter attracts anti-matter by gravity, intense annihilation= =20 radiation is expected. Since this is not observed, cosmologists concluded the universe is un-symmetrical and tailored the big-bang accordingly. But there is another possibility. The anti-symmetry of particles and anti-particles, suggests repulsive gravity. The rarity of anti-matter and the weakness of gravity makes tesing difficult. But indeed if it is repulsive, galaxies and anti-galaxies would separate and the annihilation radiation would be small as observed. A first guess is 50-50 that anti-gravity exists but there is other evidence: Gamma-ray bursts observed by NASA satellites, solar anti-neutrino flux, and a proposed wave-structure of the electron: =D2Exploring the Physics of the Unknown Universe=D3(1991), ISBN 0-9627787-0-2, suggest that anti-gravity may exist. If true, expect a rush back to the drawing board to revise the expansion and structure of the universe.

Sagebrush Ecosystems Under Fire

DOE Office of Scientific and Technical Information (OSTI.GOV)

Downs, Janelle L.

Since settlement of the western United States began, sagebrush (Artemisia L. spp.) ecosystems have decreased both in quantity and quality. Originally encompassing up to 150 million acres in the West, the “interminable fields” of sage described by early explorers (Fremont 1845) have been degraded and often eliminated by conversion to agriculture, urbanization, livestock grazing, invasion by alien plants, and alteration of wildfire cycles (Hann et al. 1997; West 1999). More than half of the original sagebrush steppe ecosystems in Washington have been converted to agriculture and many of the remaining stands of sagebrush are degraded by invasion of exotic annualsmore » such as cheatgrass (Bromus tectorum L.). Today, sagebrush ecosystems are considered to be one of the most imperiled in the United States (Noss, LeRoe and Scott 1995), and more than 350 sagebrush-associated plants and animals have been identified as species of conservation concern (Suring et al. 2005; Wisdom et al. 2005). The increasing frequency of wildfire in sagebrush-dominated landscapes is one of the greatest threats to these habitats and also presents one of the most difficult to control.« less

Monte Carlo modeling of a conventional X-ray computed tomography scanner for gel dosimetry purposes.

PubMed

Hayati, Homa; Mesbahi, Asghar; Nazarpoor, Mahmood

2016-01-01

Our purpose in the current study was to model an X-ray CT scanner with the Monte Carlo (MC) method for gel dosimetry. In this study, a conventional CT scanner with one array detector was modeled with use of the MCNPX MC code. The MC calculated photon fluence in detector arrays was used for image reconstruction of a simple water phantom as well as polyacrylamide polymer gel (PAG) used for radiation therapy. Image reconstruction was performed with the filtered back-projection method with a Hann filter and the Spline interpolation method. Using MC results, we obtained the dose-response curve for images of irradiated gel at different absorbed doses. A spatial resolution of about 2 mm was found for our simulated MC model. The MC-based CT images of the PAG gel showed a reliable increase in the CT number with increasing absorbed dose for the studied gel. Also, our results showed that the current MC model of a CT scanner can be used for further studies on the parameters that influence the usability and reliability of results, such as the photon energy spectra and exposure techniques in X-ray CT gel dosimetry.

This is a cohort study with controls in which a consecutive cohort of nineteen 2-14-year-old children who underwent focal resections for intractable partial seizures between 1996 and 2006, were matched with 19 non-surgery intractable partial epilepsy patients, and with 19 healthy subjects. The two epilepsy groups were matched for age, sex, socio-economic status (SES), cognitive level, seizure type, and seizure frequency. The healthy group was matched with the two epilepsy groups for age, sex, SES, and cognitive level. QOL was assessed using the QOLCE (Quality of Life in Childhood Epilepsy Questionnaire). In the surgery group (follow-up 3.84+/-2.26 years), 78.9% had Engel class-I versus 21.1% in non-surgery (p=0.01) (follow-up 3.44+/-2.95 years). Surgery patients were similar to healthy subjects in the social, emotional, cognitive, behavioral, and overall QOL (p>0.05) but had lower scores in the total QOL, physical, and health domains (p<0.05). Surgery patients scored better than non-surgery in the behavioral domain and the HASES (Hague Side Effects Scale) score (p<0.05). Non-surgery patients scored worse than healthy in total QOL, physical, behavioral, health, and overall QOL (p<0.05). IQ, HASS (Hague Seizure Severity Scale), and HASES scores were positively associated with total QOL score (p<0.05). Subgroup analysis on seizure-free surgery patients showed that they did not differ from healthy subjects in any of QOL domains (p>0.05, power>0.8). Our data indicate that epilepsy surgery for partial seizures in children is associated with better QOL as compared to children with intractable epilepsy who are not operated on, and suggest that in those who achieve seizure freedom normal QOL may at least potentially be possible.

Some evidence suggests that motivational approaches are less efficacious--or even counter-productive--with persons who are relatively motivated at baseline. The present study was conducted to examine whether disordinal moderation by baseline motivation could partially explain negative findings in a previous study [Winhusen, T., Kropp, F., Babcock, D., Hague, D., Erickson, S.J., Renz, C., Rau, L., Lewis, D., Leimberger, J., Somoza, E., 2008. Motivational enhancement therapy to improve treatment utilization and outcome in pregnant substance users. J. Subst. Abuse Treat. 35, 161-173]. Analyses also focused on the relative utility of the University of Rhode Island Change Assessment (URICA) scale, vs. a single goal question as potential moderators of Motivation Enhancement Therapy (MET). Participants were 200 pregnant women presenting for substance abuse treatment at one of four sites. Women were randomly assigned to either a three-session MET condition or treatment as usual (TAU). Generalized Estimating Equations (GEE) revealed no significant moderation effects on drug use at post-treatment. At follow-up, contrary to expectations, participants who had not set a clear quit goal at baseline were less likely to be drug-free if randomized to MET (OR=0.48); participants who did set a clear quit goal were more likely to be drug-free if randomized to MET (OR=2.53). No moderating effects were identified via the URICA. Disordinal moderation of MET efficacy by baseline motivation may have contributed somewhat to the negative results of the [Winhusen, T., Kropp, F., Babcock, D., Hague, D., Erickson, S.J., Renz, C., Rau, L., Lewis, D., Leimberger, J., Somoza, E., 2008. Motivational enhancement therapy to improve treatment utilization and outcome in pregnant substance users. J. Subst. Abuse Treat. 35, 161-173] study, but in the opposite direction expected. A simple question regarding intent to quit may be useful in identifying persons who may differentially respond to motivational

Prototypes for Content-Based Image Retrieval in Clinical Practice

2011-01-01

Content-based image retrieval (CBIR) has been proposed as key technology for computer-aided diagnostics (CAD). This paper reviews the state of the art and future challenges in CBIR for CAD applied to clinical practice. We define applicability to clinical practice by having recently demonstrated the CBIR system on one of the CAD demonstration workshops held at international conferences, such as SPIE Medical Imaging, CARS, SIIM, RSNA, and IEEE ISBI. From 2009 to 2011, the programs of CADdemo@CARS and the CAD Demonstration Workshop at SPIE Medical Imaging were sought for the key word “retrieval” in the title. The systems identified were analyzed and compared according to the hierarchy of gaps for CBIR systems. In total, 70 software demonstrations were analyzed. 5 systems were identified meeting the criterions. The fields of application are (i) bone age assessment, (ii) bone fractures, (iii) interstitial lung diseases, and (iv) mammography. Bridging the particular gaps of semantics, feature extraction, feature structure, and evaluation have been addressed most frequently. In specific application domains, CBIR technology is available for clinical practice. While system development has mainly focused on bridging content and feature gaps, performance and usability have become increasingly important. The evaluation must be based on a larger set of reference data, and workflow integration must be achieved before CBIR-CAD is really established in clinical practice. PMID:21892374

Residential outcomes of forced relocation: lifting a corner of the veil on neighbourhood selection.

PubMed

Doff, Wenda; Kleinhans, Reinout

2011-01-01

Fear of the detrimental effects of ethnic segregation has pervaded the debate on the population composition of cities and neighbourhoods. However, little is known about mechanisms underlying the spatial sorting of ethnic minorities. Hence, policies aimed at desegregation may result in exactly the opposite - that is, new ethnic concentrations and segregation. This paper studies the residential outcomes of 658 forced movers from urban restructuring areas in The Hague. Compared with "native" Dutch (those with both parents born in the Netherlands), ethnic minorities report neighbourhood improvement less often and are more likely to stay within or move into other ethnically concentrated neighbourhoods. These differences are not fully explained by differences in individual characteristics, resources, institutional factors, pre-relocation preferences or other relocation outcomes. Ethnic specificities in neighbourhood choices thus remain a pressing issue for further research.

We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

According to an obscure medieval legend, the Countess Margaret of Henneberg, a notable Dutch noblewoman, gave birth to 365 children in the year 1276. The haughty Countess had insulted a poor beggar woman carrying twins, since she believed that a pair of twins must have different fathers, and that their mother must be an adultress. She was punished by God, and gave birth to 365 minute children on Good Friday, 1276. The Countess died shortly after, together with her offspring, in the village of Loosduinen near The Hague. The Countess and her numerous brood were frequently described in historical and obstetrical works. To this day, a memorial tablet and two basins, representing those in which the 365 children were baptized, are to be seen in the church of Loosduinen.

Suicide death and hospital-treated suicidal behaviour in asylum seekers in the Netherlands: a national registry-based study

PubMed Central

2011-01-01

Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. Methods We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+). The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. Results The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83). No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07). The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. Conclusions In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour was higher in several

Preliminary volcano hazard assessment for the Emmons Lake volcanic center, Alaska

USGS Publications Warehouse

Waythomas, Christopher; Miller, Thomas P.; Mangan, Margaret T.

2006-01-01

The Emmons Lake volcanic center is a large stratovolcano complex on the Alaska Peninsula near Cold Bay, Alaska. The volcanic center includes several ice- and snow-clad volcanoes within a nested caldera structure that hosts Emmons Lake and truncates a shield-like ancestral Mount Emmons edifice. From northeast to southwest, the main stratovolcanoes of the center are: Pavlof Sister, Pavlof, Little Pavlof, Double Crater, Mount Hague, and Mount Emmons. Several small cinder cones and vents are located on the floor of the caldera and on the south flank of Pavlof Volcano. Pavlof Volcano, in the northeastern part of the center, is the most historically active volcano in Alaska (Miller and others, 1998) and eruptions of Pavlof pose the greatest hazards to the region. Historical eruptions of Pavlof Volcano have been small to moderate Strombolian eruptions that produced moderate amounts of near vent lapilli tephra fallout, and diffuse ash plumes that drifted several hundreds of kilometers from the vent. Cold Bay, King Cove, Nelson Lagoon, and Sand Point have reported ash fallout from Pavlof eruptions. Drifting clouds of volcanic ash produced by eruptions of Pavlof would be a major hazard to local aircraft and could interfere with trans-Pacific air travel if the ash plume achieved flight levels. During most historical eruptions of Pavlof, pyroclastic material erupted from the volcano has interacted with the snow and ice on the volcano producing volcanic mudflows or lahars. Lahars have inundated most of the drainages heading on the volcano and filled stream valleys with variable amounts of coarse sand, gravel, and boulders. The lahars are often hot and would alter or destroy stream habitat for many years following the eruption. Other stratocones and vents within the Emmons Lake volcanic center are not known to have erupted in the past 300 years. However, young appearing deposits and lava flows suggest there may have been small explosions and minor effusive eruptive activity

South Asian migrants are at particularly high risk of type 2 diabetes. Previous studies have shown that intensive lifestyle interventions may prevent the onset of diabetes. Such interventions have not been culturally adapted and evaluated among South Asians in industrialized countries. Therefore, we have set up a randomized controlled trial to study the effectiveness of a targeted lifestyle intervention for the risk of type 2 diabetes and cardiovascular risk factors among 18 to 60-year-old Hindustani Surinamese (South Asians) in The Hague, the Netherlands. Here we present the study design and describe the characteristics of those recruited. Between May 18, 2009 and October 11, 2010, we screened 2307 Hindustani Surinamese (18-60 years old) living in The Hague. We sent invitations to participate to those who had an impaired fasting glucose of 5.6-6.9 mmol/l, an impaired glucose tolerance of 7.8-11.0 mmol/L, a glycated hemoglobin level of 6.0% or more and/or a value of 2.39 or more for the homeostasis model assessment of estimated insulin resistance. In total, 536 people (56.1% of those eligible) participated. People with a higher level of education and a family history of type 2 diabetes were more likely to participate. The control and intervention groups were similar with regard to important background characteristics. The intervention group will receive a culturally targeted intervention consisting of dietary counseling using motivational interviewing and a supervised physical activity program. The control group will receive generic lifestyle advice. To determine the effectiveness, a physical examination (anthropometrics, cardiorespiratory test, lipid profile, and measures of oral glucose tolerance, glycated hemoglobin, and insulin) and interview (physical activity, diet, quality of life, and intermediate outcomes) were carried out at baseline and will be repeated at 1 year and 2 years. The process and the costs will be evaluated. This trial will provide

Bell's palsy before Bell: Cornelis Stalpart van der Wiel's observation of Bell's palsy in 1683.

PubMed

2005-11-01

Bell's palsy is named after Sir Charles Bell (1774-1842), who has long been considered to be the first to describe idiopathic facial paralysis in the early 19th century. However, it was discovered that Nicolaus Anton Friedreich (1761-1836) and James Douglas (1675-1742) preceded him in the 18th century. Recently, an even earlier account of Bell's palsy was found, as observed by Cornelis Stalpart van der Wiel (1620-1702) from The Hague, The Netherlands in 1683. Because our current knowledge of the history of Bell's palsy before Bell is limited to a few documents, it is interesting to discuss Stalpart van der Wiel's description and determine its additional value for the history of Bell's palsy. It is concluded that Cornelis Stalpart van der Wiel was the first to record Bell's palsy in 1683. His manuscript provides clues for future historical research.

The recent risk assessment by the North-Cotentin Radioecology Group (, 1999) outlined that (14)C has become one of the major sources of the low dose to man through seafood consumption. It was recommended that more data should be collected about (14)C in the local marine environment. The present study aims to respond to this recommendation. The estimation of (14)C activity in marine species is based on concentration factor values. The values reported here ranged from 1x10(3) to 5x10(3)Bqkg(-1)ww/BqL(-1). A comparison was made between the observed and predicted values. The accuracy of (14)C activity calculations was estimated between underestimation by a factor of 2 and over-estimation by 50% (95% confidence interval). However, the use of the concentration factor parameter is based on the biological and seawater compartments being in steady state. This assumption may not be met at short distances from the point of release of discharges, where rapid changes in seawater concentration may be smoothed out in living organisms due to transfer kinetics. The data processing technique, previously published by Fiévet and Plet (2003. Estimating biological half-lives of radionuclides in marine compartments from environmental time-series measurements. Journal of Environmental Radioactivity 65, 91-107), was used to deal with (14)C transfer kinetics, and carbon half-lives between seawater and a few biological compartments were thus estimated.

129I in the oceans: origins and applications.

PubMed

Raisbeck, G M; Yiou, F

1999-09-30

The quantity of the long lived (half-life 15.7 million years) radioactive isotope 129I in the pre-nuclear age ocean was approximately 100 kg. Various nuclear related activities, including weapons testing, nuclear fuel reprocessing, Chernobyl and other authorized or non-authorized dumping of radioactive waste have increased the ocean inventory of 129I by more than one order of magnitude. The most important of these sources are the direct marine discharges from the commercial reprocessing facilities at La Hague (France) and Sellafield (UK) which have discharged approximately 1640 kg in the English Channel, and approximately 720 kg in the Irish Sea, respectively. We discuss how this 129I can be used as both a 'pathway' and 'transit time' tracer in the North Atlantic and Arctic oceans, as well as a parameter for distinguishing between reprocessed and non-reprocessed nuclear waste in the ocean, and as a proxy for the transport and dilution of other soluble pollutants input to the North Sea.

Samuel Goudsmit, born in 1902 in The Hague, Netherlands, earned his Ph.D. at the University of Leiden in 1926 with Paul Ehrenfest. The present talk will describe some aspects of his background and early formative years in order to provide context for the broad range of his professional life. Sam belonged to a large tribe of paternal and maternal uncles, aunts and first cousins; including his parents, grandparents and sister Ro, they numbered forty.

Green trees for greenhouse gases: a fair trade-off?

PubMed

Schmidt, C W

2001-03-01

While forests retain carbon in plants, detritus, and soils, utility companies spew it into the air as carbon dioxide, the main greenhouse gas behind global warming. Industrial carbon dioxide emissions aren't currently regulated by federal law, but a number of companies are trying to address the problem voluntarily by launching carbon sequestration programs in heavily forested countries, where carbon is contained in so-called sinks. But the November 2000 meeting of the Kyoto Protocol delegates in The Hague collapsed over the issue of the acceptability of carbon sinks as a source of carbon pollution credits, delivering what many see as a deathblow to the concept. At issue are a host of ecological and statistical questions, differing local land use practices, cultural factors, issues of verifiability, and even disagreement over definitions of basic terms such as "forest" Kyoto negotiators are gearing up for another round of discussions in Bonn in May 2001, and it is likely that the continuing debate over carbon sinks will dominate the agenda.

On the interaction of sound with an annular aperture in a mean flow duct

NASA Astrophysics Data System (ADS)

Schleicher, R. M.; Howe, M. S.

2013-10-01

An analysis is made of long wavelength sound interacting with a thin, rigid disc placed axisymmetrically across a circular cylindrical duct in the presence of a low Mach number mean flow. Vorticity produced at the edge of the disc causes an overall loss of acoustic energy, the effect of which is increased by the flow. Calculations are performed to derive a new analytical representation of the Rayleigh conductivity of the annular aperture between the disc and the duct wall, and a quasi-steady approximation is used to determine the unsteady drag on the disc. The results are used to estimate the corrected form of the conductivity in the presence of flow. This permits the Cummings-Fant ‘reduced complexity’ equation to be applied to study the absorption of acoustic energy at the disc [A. Cummings, American Institute of Aeronautics and Astronautics Journal 22 (1984) 786-792; G. Fant, Acoustic Theory of Speech Production, The Hague, Mouton, 1960].

Commercial surrogacy: how provisions of monetary remuneration and powers of international law can prevent exploitation of gestational surrogates.

Ramskold, Louise Anna Helena; Posner, Marcus Paul

2013-06-01

Increasing globalisation and advances in artificial reproductive techniques have opened up a whole new range of possibilities for infertile couples across the globe. Inter-country gestational surrogacy with monetary remuneration is one of the products of medical tourism meeting in vitro fertilisation embryo transfer. Filled with potential, it has also been a hot topic of discussion in legal and bioethics spheres. Fears of exploitation and breach of autonomy have sprung from the current situation, where there is no international regulation of surrogacy agreements--only a web of conflicting national laws that generates loopholes and removes safeguards for both the surrogate and commissioning couple. This article argues the need for evidence-based international laws and regulations as the only way to resolve both the ethical and legal issues around commercial surrogacy. In addition, a Hague Convention on inter-country surrogacy agreements is proposed to resolve the muddled state of affairs and enable commercial surrogacy to demonstrate its full potential.

A report that presented at the World Forum II at The Hague in March 2000, said that it would be water crisis around the world and some countries will be lack of water in 2025, as a result of global studies. Inefficient using of water and considering water as free goods which means it can be used as much as we want without any lost. Thus, it causes wasteful consumption and low public awareness in using water without effort to preserve and conserve the water resources. In addition, the excessive exploitation of ground water for industrial facilities also leads to declining of available freshwater. Therefore, this paper reviews some problems arise all over the world regarding to improper and improving management, policies and methods to determine the optimum model of freshwater price in order to avoid its wasteful thus ensuring its sustainability. In this paper, we also proposed a preliminary model of water pricing represents a case of Medan, North Sumatera, Indonesia.

Implementation fidelity, a critical aspect of clinical trials research that establishes adequate delivery of the treatment as prescribed in treatment manuals and protocols, is also essential to the successful implementation of effective programs into new practice settings. Although infrequently studied in the drug abuse field, stronger implementation fidelity has been linked to better outcomes in practice but appears to be more difficult to achieve with greater distance from model developers. In the INternational CAnnabis Need for Treatment (INCANT) multi-national randomized clinical trial, investigators tested the effectiveness of Multidimensional Family Therapy (MDFT) in comparison to individual psychotherapy (IP) in Brussels, Berlin, Paris, The Hague, and Geneva with 450 adolescents with a cannabis use disorder and their parents. This study reports on the implementation fidelity of MDFT across these five Western European sites in terms of treatment adherence, dose and program differentiation, and discusses possible implications for international implementation efforts.

Neurosurgical treatment may improve seizures in children and adolescents with drug-resistant epilepsy, but additional data are needed from randomized trials. In this single-center trial, we randomly assigned 116 patients who were 18 years of age or younger with drug-resistant epilepsy to undergo brain surgery appropriate to the underlying cause of epilepsy along with appropriate medical therapy (surgery group, 57 patients) or to receive medical therapy alone (medical-therapy group, 59 patients). The patients in the medical-therapy group were assigned to a waiting list for surgery. The primary outcome was freedom from seizures at 12 months. Secondary outcomes were the score on the Hague Seizure Severity scale, the Binet-Kamat intelligence quotient, the social quotient on the Vineland Social Maturity Scale, and scores on the Child Behavior Checklist and the Pediatric Quality of Life Inventory. At 12 months, freedom from seizures occurred in 44 patients (77%) in the surgery group and in 4 (7%) in the medical-therapy group (P<0.001). Between-group differences in the change from baseline to 12 months significantly favored surgery with respect to the score on the Hague Seizure Severity scale (difference, 19.4; 95% confidence interval [CI], 15.8 to 23.1; P<0.001), on the Child Behavior Checklist (difference, 13.1; 95% CI, 10.7 to 15.6; P<0.001), on the Pediatric Quality of Life Inventory (difference, 21.9; 95% CI, 16.4 to 27.6; P<0.001), and on the Vineland Social Maturity Scale (difference, 4.7; 95% CI, 0.4 to 9.1; P=0.03), but not on the Binet-Kamat intelligence quotient (difference, 2.5; 95% CI, -0.1 to 5.1; P=0.06). Serious adverse events occurred in 19 patients (33%) in the surgery group, including hemiparesis in 15 (26%). In this single-center trial, children and adolescents with drug-resistant epilepsy who had undergone epilepsy surgery had a significantly higher rate of freedom from seizures and better scores with respect to behavior and quality of life than did

Re-examining the effect of low and intermediate mode number perturbations on Ignition Metrics Scaling Laws

2017-10-01

We re-examine the way 2/3D effects on scaling laws for ignition metrics, such as the generalized Lawson Criterion (GLC) and the Ignition Threshold Factor (ITF). These scaling laws were derived for 1D symmetrical case and 2/3D perturbations [Hann et al. PoP 2010; Lindl et al., PoP 2014; Betti et al., PoP 2010]. The main cause for the difference between the 1D and the 2/3D scaling laws in those works, is heat conduction losses from the hot-spot bubbles to the cold shell [Kishony and Shvarts, PoP 2001]. This ``dry out'' of the bubbles is the dominant mechanism for intermediate mode number perturbations (6

Worldwide governmental efforts to locate and destroy chemical weapons and weapons materials: minimizing risk in transport and destruction.

Trapp, Ralf

2006-09-01

The article gives an overview on worldwide efforts to eliminate chemical weapons and facilities for their production in the context of the implementation of the 1997 Chemical Weapons Convention (CWC). It highlights the objectives of the Organisation for the Prohibition of Chemical Weapons (OPCW), the international agency set up in The Hague to implement the CWC, and provides an overview of the present status of implementation of the CWC requirements with respect to chemical weapons (CW) destruction under strict international verification. It addresses new requirements that result from an increased threat that terrorists might attempt to acquire or manufacture CW or related materials. The article provides an overview of risks associated with CW and their elimination, from storage or recovery to destruction. It differentiates between CW in stockpile and old/abandoned CW, and gives an overview on the factors and key processes that risk assessment, management, and communication need to address. This discussion is set in the overall context of the CWC that requires the completion of the destruction of all declared CW stockpiles by 2012 at the latest.

The topic of this article is sexual violence in context with war-like conflicts in the former Yugoslavia and Rwanda. The fundamental categories of sexual violence in war-like conflicts are described. The authors discuss the types of sexual violence as defined in the report of the UN Commission of Experts on the war-like conflicts in the former Yugoslavia. Four criminal trials were evaluated: three held before the International Criminal Tribunal for the Former Yugoslavia (ICTY) in The Hague/Netherlands and one before the International Criminal Tribunal for Rwanda (ICTR) in Arusha/Tansania. The defendants were found guilty of torture, crime against humanity and genocide. Potential procedures with respect to similar crimes in current or prospective conflicts are discussed. An alternative may be the assignment of medical personnel (for example of the German Federal Armed Forces). Finally, the post-war cooperation between the Institute of Legal Medicine at the University Medical Centre of Hamburg-Eppendorf as well as the medical and government institutions in Rwanda is presented, which has been going on since 2005.

1999-01-01

Three fora, namely, the Parliamentarian's Forum, the Nongovernmental Organization (NGO) Forum, and the Youth Forum, immediately preceded the Hague Forum. Each of the forums assessed achievements in implementing the International Conference on Population and Development Programme of Action (ICPD-PA) and formulated recommendations that provided valuable input to the International Forum. The Parliamentarian's Forum, attended by 210 parliamentarians from 103 countries, evaluated the progress in development of the parliamentarians' movement after the ICPD. The parliamentarians focused their discussions on the following priority areas: reproductive health and rights; gender and population; adolescents, youth, the elderly, and persons with disabilities; population, environment, and food security; resource mobilization; economic crises; and parliamentarian networks. The NGO Forum, on the other hand, emphasized the need to achieve consensus on policy formulation that includes NGOs as partners; establish permanent mechanisms for ICPD-PA implementation; and mobilize financial resources for sexual and reproductive health initiatives. Lastly, the Youth Forum highlighted the central role that youth can play in the development of policies and programs for ICPD-PA implementation.

In 2009 and 2010, the Institute for Nuclear Safety and Radiation Protection (IRSN) led two pilot actions dealing with nuclear installations' safety cases. One concerned the periodical review of the French 900 MWe nuclear reactors, the other concerned the decommissioning of a workshop located on the site of Areva's La Hague fuel-reprocessing plant site in Northwestern France. The purpose of both these programs was to test ways for IRSN and a small number of stakeholders (Non-Governmental Organizations (NGOs) members, local elected officials, etc.) to engage in technical discussions. The discussions were intended to enable the stakeholders to review future applicationsmore » and provide valuable input. The test cases confirmed there is a definite challenge in successfully opening a meaningful dialogue to discuss technical issues, in particular the fact that most expertise reports were not public and the conflict that exists between the contrary demands of transparency and confidentiality of information. The test case also confirmed there are ways to further improvement of stakeholders' involvement. (authors)« less

[The court physician, the clergyman, a learned society and smallpox].

PubMed

Hillen, H F P

2017-01-01

Variolation was introduced in England in the first half of the 18th century. The positive effects of this new method for preventing smallpox were already known in the Netherlands around 1720, one of whom was the Dutch physician Boerhaave. In spite of this, it took another 30 years before variolation was used in the Netherlands. Despite receiving positive advice and information from his learned English friends Sloane and Sherard, Boerhaave did not apply nor advise the use of variolation. There were various arguments for this restrained approach. In 1754 Thomas Schwencke found that conditions were favourable for the introduction of variolation in The Hague. There was support from the House of Orange-Nassau (the current royal family in the Netherlands) and from a learned society; a highly motivated clergyman acted as ambassador for the new technique and the court physician Schwencke was willing to take the lead. A similar combination had previously been effective in England, though the ambassador there was not a clergyman but an influential noble lady.

2003-01-01

The discovery of a national inquiry into health funds in the 1840s gives cause to reconsider the traditional view on this subject. After a prosperous period under the guild regime commercial interests penetrated the health market. Its directors supposedly enriched themselves at the expense of both the insured and the professionals (general practitioners (gp's) and chemists). As things grew worse the government intervened and ordered an inquiry by a Select Committee. In reality things were slightly different. The debate on heath insurance was part and parcel of the pursuit of the medical profession to improve its standing. An alarming report on health funds by the Amsterdam medical commission spurred the Health Department to action. The national inquiry did not in fact corroborate the earlier report. In most parts of the Netherlands health insurance did not exist. In only two provinces - North and South Holland - taking out health insurance was an option and even there it was to a large extent in the cities. The three big cities - Amsterdam, Rotterdam and The Hague - accounted for 51.8 percent of all funds and as much as 72.2 percent of all persons insured. Nearly all complaints in the 1840s originated from gp's in Amsterdam. Only The Hague had the same experience i.e. infringements on private practice, enrichment by the fund governors etc. The complaints were not unlike those of the English club doctors at the end of the century. In both cities commercial health funds were important, while in Rotterdam gp's had very often been founding fathers. The author has tried to put the complaints into a wider perspective by comparing commercial funds with local clubs' and gp's own fund, the AZA, founded in 1847 to combat the disputed trend. Finally commercial funds have been compared with medical relief (number of patients and paid fees). The complaints about remuneration seem exaggerated as even AZA could not afford to pay higher fees. Commercialisation had only just

In 2009, Savannah River Remediation LLC (SRR) assumed the management lead of the Liquid Waste (LW) Program at the Savannah River Site (SRS). The four SRR partners and AREVA, as an integrated subcontractor are performing the ongoing effort to safely and reliably: - Close High Level Waste (HLW) storage tanks; - Maximize waste throughput at the Defense Waste Processing Facility (DWPF); - Process salt waste into stable final waste form; - Manage the HLW liquid waste material stored at SRS. As part of these initiatives, SRR and AREVA deployed a performance management methodology based on Overall Equipment Effectiveness (OEE) atmore » the DWPF in order to support the required production increase. This project took advantage of lessons learned by AREVA through the deployment of Total Productive Maintenance and Visual Management methodologies at the La Hague reprocessing facility in France. The project also took advantage of measurement data collected from different steps of the DWPF process by the SRR team (Melter Engineering, Chemical Process Engineering, Laboratory Operations, Plant Operations). Today the SRR team has a standard method for measuring processing time throughout the facility, a reliable source of objective data for use in decision-making at all levels, and a better balance between engineering department goals and operational goals. Preliminary results show that the deployment of this performance management methodology to the LW program at SRS has already significantly contributed to the DWPF throughput increases and is being deployed in the Saltstone facility. As part of the liquid waste program on Savannah River Site, SRR committed to enhance production throughput of DWPF. Beyond technical modifications implemented at different location of the facility, SRR deployed performance management methodology based on OEE metrics. The implementation benefited from the experience gained by AREVA in its own facilities in France. OEE proved to be a valuable tool in

Oscillations in motor unit discharge are reflected in the low-frequency component of rectified surface EMG and the rate of change in force.

PubMed

Yoshitake, Yasuhide; Shinohara, Minoru

2013-11-01

Common drive to a motor unit (MU) pool manifests as low-frequency oscillations in MU discharge rate, producing fluctuations in muscle force. The aim of the study was to examine the temporal correlation between instantaneous MU discharge rate and rectified EMG in low frequencies. Additionally, we attempted to examine whether there is a temporal correlation between the low-frequency oscillations in MU discharge rate and the first derivative of force (dF/dt). Healthy young subjects produced steady submaximal force with their right finger as a single task or while maintaining a pinch-grip force with the left hand as a dual task. Surface EMG and fine-wire MU potentials were recorded from the first dorsal interosseous muscle in the right hand. Surface EMG was band-pass filtered (5-1,000 Hz) and full-wave rectified. Rectified surface EMG and the instantaneous discharge rate of MUs were smoothed by a Hann-window of 400 ms duration (equivalent to 2 Hz low-pass filtering). In each of the identified MUs, the smoothed MU discharge rate was positively correlated with the rectified-and-smoothed EMG as confirmed by the distinct peak in cross-correlation function with greater values in the dual task compared with the single task. Additionally, the smoothed MU discharge rate was temporally correlated with dF/dt more than with force and with rectified-and-smoothed EMG. The results indicated that the low-frequency component of rectified surface EMG and the first derivative of force provide temporal information on the low-frequency oscillations in the MU discharge rate.

Time-dependent multi-dimensional simulation studies of the electron output scheme for high power FELs

Hahn, S. J.; Fawley, W. M.; Kim, K.-J.; Edighoffer, J. A.

1995-04-01

We examine the performance of the so-called electron output scheme recently proposed by the Novosibirsk group [G.I. Erg et al., 15th Int. Free Electron Laser Conf., The Hague, The Netherlands, 1993, Book of Abstracts p. 50; Preprint Budker INP 93-75]. In this scheme, the key role of the FEL oscillator is to induce bunching, while an external undulator, called the radiator, then outcouples the bunched electron beam to optical energy via coherent emission. The level of the intracavity power in the oscillator is kept low by employing a transverse optical klystron (TOK) configuration, thus avoiding excessive thermal loading on the cavity mirrors. Time-dependent effects are important in the operation of the electron output scheme because high gain in the TOK oscillator leads to sideband instabilities and chaotic behavior. We have carried out an extensive simulation study by using 1D and 2D time-dependent codes and find that proper control of the oscillator cavity detuning and cavity loss results in high output bunching with a narrow spectral bandwidth. Large cavity detuning in the oscillator and tapering of the radiator undulator is necessary for the optimum output power.

Innovative Use of the Law to Address Complex Global Health Problems Comment on "The Legal Strength of International Health Instruments - What It Brings toGlobal Health Governance?"

PubMed

Walls, Helen L; Ooms, Gorik

2017-05-20

Addressing the increasingly globalised determinants of many important problems affecting human health is a complex task requiring collective action. We suggest that part of the solution to addressing intractable global health issues indeed lies with the role of new legal instruments in the form of globally binding treaties, as described in the recent article of Nikogosian and Kickbusch. However, in addition to the use of international law to develop new treaties, another part of the solution may lie in innovative use of existing legal instruments. A 2015 court ruling in The Hague, which ordered the Dutch government to cut greenhouse gas emissions by at least 25% within five years, complements this perspective, suggesting a way forward for addressing global health problems that critically involves civil society and innovative use of existing domestic legal instruments. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Assessment of crew operations during internal servicing of the Columbus Free-Flyer by Hermes

NASA Astrophysics Data System (ADS)

Winisdoerffer, F.; Lamothe, A.; Bourdeau'hui, J. C.

The Hermes system has been adopted as a European programme at the Hague ministerial level meeting. The primary mission of the Hermes spaceplane will be the servicing of the Columbus Free-Flyer (CFF) in order to bring new experiments in orbit, recover the results of old ones, and refurbish/maintain the various subsystems. This mission will be based on the extensive use of the 3 crewmembers on-board Hermes in order to perform either the Intra-Vehicular (IVA) and/or the Extra-Vehicular (EVA) activities. This paper focuses on the internal operations and the dimensions of the various payload of the basic reference cargo set are presented. The main constraints associated with their manipulation are also assessed independently of the configuration. During the spaceplane definition process, various configurations were developed. The operations were simulated using the CAD CATIA software with representative anthropometric models of the potential Hermes users population. These simulations helped to assess the various configurations and to refine the general concept of the spaceplane. The geometrical feasibility is demonstrated through those simulations. However full-scale tests are required to confirm data and assess the duration of the operations.

Using social justice as the conceptual foundation, the authors present the structural barriers to socially just intercountry adoptions (ICAs) that can exploit and oppress vulnerable children and families participating in ICAs. They argue that such practices threaten the integrity of social work practice in that arena and the survival of ICA as a placement option. Government structures, disparity of power between countries and families on both sides, perceptions regarding poverty, cultural incompetence, misconceptions about orphans and orphanages, lack of knowledge about the impact of institution-based care, and the profit motive are driving forces behind the growing shadow of unethical ICAs. The U.S. social work community has a large role and responsibility in addressing these concerns as the United States receives the most children adopted through ICAs of all receiving countries. In addition to the centrality of social justice as a core value of the profession, the responsibility to carry out ethical and socially just ICA has recently increased as a matter of law, under the implementation legislation to the Hague Convention on Intercountry Adoption. While acknowledging that these issues are complex, authors provide suggestions for corrective policy and practice measures.

Summary Burn injury is a ubiquitous threat in the military environment, and war burns have been described for more than 5,000 years of written history. Fire was probably utilized as a weapon long before that. With the ever-increasing destructive power and efficiency of modern weapons, casualties, both fatal and non-fatal, are reaching new highs, particularly among civilians who are becoming the major wartime targets in recent wars, accounting for most of the killed and wounded. Even though medical personnel usually believe that a knowledge of weaponry has little relevance to their ability to effectively treat injuries and that it may in some way be in conflict with their status, accorded under the Geneva and Hague treaties, it is imperative that they know how weapons are used and understand their effects on the human body. The present review explores various categories of weapons of modern warfare that are unfamiliar to most medical and paramedical personnel responsible for burn treatment. The mechanisms and patterns of injury produced by each class of weapons are examined so that a better understanding of burn management in a warfare situation may be achieved. PMID:21991098

MDFT (Multidimensional Family Therapy) is a family based outpatient treatment programme for adolescent problem behaviour. MDFT has been found effective in the USA in adolescent samples differing in severity and treatment delivery settings. On request of five governments (Belgium, France, Germany, the Netherlands, and Switzerland), MDFT has now been tested in the joint INCANT trial (International Cannabis Need of Treatment) for applicability in Western Europe. In each of the five countries, study participants were recruited from the local population of youth seeking or guided to treatment for, among other things, cannabis use disorder. There is little information in the literature if these populations are comparable between sites/countries or not. Therefore, we examined if the study samples enrolled in the five countries differed in baseline characteristics regarding demographics, clinical profile, and treatment delivery setting. INCANT was a multicentre phase III(b) randomized controlled trial with an open-label, parallel group design. It compared MDFT with treatment as usual (TAU) at and across sites in Berlin, Brussels, Geneva, The Hague and Paris.Participants of INCANT were adolescents of either sex, from 13 through 18 years of age, with a cannabis use disorder (dependence or abuse), and at least one parent willing to take part in the treatment. In total, 450 cases/families were randomized (concealed) into INCANT. We collected data about adolescent and family demographics (age, gender, family composition, school, work, friends, and leisure time). In addition, we gathered data about problem behaviour (substance use, alcohol and cannabis use disorders, delinquency, psychiatric co-morbidity).There were no major differences on any of these measures between the treatment conditions (MDFT and TAU) for any of the sites. However, there were cross-site differences on many variables. Most of these could be explained by variations in treatment culture, as reflected by

All but three of the 270 women surviving eclampsia at the Margaret Hague Maternity Hospital in the period 1931 through 1951 were traced to 1973-74. Seventy-six have died and 13 were not re-examined. In white women having eclampsia in the first pregnancy carried to viability the remote mortality rate is not increased over that in unselected women; in white women having eclampsia as mulitparas and in all black women the remote mortality rate is from 2 to 5 times the expected numbers. Primiparous eclamptic women are not different from women matched for age, in several epidemiologic studies, in the prevalence of hypertension or in the frequency distributions of systolic and diastolic blood pressures. There is, however, a considerable increase in the prevalence of hypertension among women having had eclampsia as multiparas and that has accounted for their increased remote death rates. The prevalence of diabetes, developing many years after eclampsia is 2.5 times the expected rate in primiparous and about 4 times the expected rate among multiparous eclamptic women. Eclampsia neither is a sign of latent essential hypertension nor causes hypertension. Hypertensive pregnancies following eclampsia indicate the probabilty of later chronic hypertension, but do not cause it.

This article summarizes the outcome of the discussions at the international workshop on nano reference values (NRVs), which was organized by the Dutch trade unions and employers' organizations and hosted by the Social Economic Council in The Hague in September 2011. It reflects the discussions of 80 international participants representing small- and medium-size enterprises (SMEs), large companies, trade unions, governmental authorities, research institutions, and non-governmental organizations (NGOs) from many European countries, USA, India, and Brazil. Issues that were discussed concerned the usefulness and acceptability of precaution-based NRVs as a substitute for health-based occupational exposure limits (OELs) and derived no-effect levels (DNELs) for manufactured nanoparticles (NPs). Topics concerned the metrics for measuring NPs, the combined exposure to manufactured nanomaterials (MNMs) and process-generated NPs, the use of the precautionary principle, the lack of information about the presence of nanomaterials, and the appropriateness of soft regulation for exposure control. The workshop concluded that the NRV, as an 8-h time-weighted average, is a comprehensible and useful instrument for risk management of professional use of MNMs with a dispersible character. The question remains whether NRVs, as advised for risk management by the Dutch employers' organization and trade unions, should be under soft regulation or that a more binding regulation is preferable.

Background: Exposure to parental suicide attempt is associated with higher risks of adverse outcomes like lower educational performance, drug abuse and delinquent behavior. When a patient is hospitalized after a suicide attempt, this presents a unique opportunity to identify whether the patient has children, and thereby provide adequate follow-up for both the parent/patient and their children. The objective of this paper was to review the existing literature on follow-up measures for children subjected to parental suicide attempt. Methods: In line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we conducted a systematic literature search. Results: The search resulted in a total of 1275 article titles, of which all abstracts were screened. Out of these, 72 full text papers were read, and a final four articles were included. Three of the included papers described parts of the same study from an emergency department in The Hague, where a protocol was implemented for monitoring and referring children of parents attempting suicide. The fourth article described the association between maternal attempted suicide and risk of abuse or neglect of their children. Conclusions: The lack of research in this particular area is striking. The circumstances surrounding a parent’s suicide attempt call for appropriate familial care. PMID:29738447

Radioactivity measurements were conducted on seawater, sediment, and biota samples collected in the vicinity of the Russian submarine "Kursk" in September, 2000, within 1 month of the vessel's sinking in the Barents Sea to determine whether leakage of radioactivity from the vessel's two nuclear reactors had occurred and to assess the impact on one of the most productive fishing areas in the world. Levels of radioactivity in surface sediments and biota are within the range of values previously measured in the Barents Sea and can be ascribed to inputs from global fallout, European nuclear fuel reprocessing facilities, and the Chernobyl accident. However, levels of 1291 in seawater in the Southern Barents Sea increased by 500% between 1992 and 2000, and the 129I/137Cs ratio increased by more than an order of magnitude during this time, owing to long-range transport of releases from reprocessing facilities at Sellafield (U.K.) and La Hague (France). Although these results indicate that, at the time of sampling, leakage from the Kursk had a negligible impact on the environment, they also show that regional background levels of artificial radioactivity are varying rapidly on annual timescales and that Europe's nuclear reprocessing facilities are the leading contributor of anthropogenic radioactivity to the region.

COMMERCIAL SURROGACY: WHAT ROLE FOR LAW IN AUSTRALIA?

PubMed

Sifris, Ronli; Ludlow, Karinne; Sifris, Adiva

2015-12-01

This editorial begins by illuminating current conversations regarding the regulation of commercial surrogacy in Australia. It defines "commercial surrogacy" and explains the interaction between changes in social attitudes and changes to the law before setting out the current Australian law and practice in this area. An examination of current domestic law and practice reveals that surrogacy legislation in Australia is mired in inconsistencies and a lack of uniformity but that the one key common element is the prohibition of commercial surrogacy. The inability of couples to access commercial surrogacy within Australia has led to offshore reproductive tourism and unpredictable, contradictory decision-making as the Family Court attempts to apply legislation which was never intended to apply in this context. The editorial then turns to consider the international arena, discussing the approach of the Hague Conference on Private International Law before delving into a human rights analysis of commercial surrogacy arrangements. The adoption of a rights-based approach requires an analysis of this vexed issue from the perspective of the child, surrogate and intending parents. While questions surrounding the human rights implications of legalising commercial surrogacy continue to be the subject of passionate debate, the authors believe that the human rights of all parties are best protected through appropriate regulation rather than absolute prohibition.

To evaluate the association between risk perception and attendance in a diabetes prevention programme among South Asians with a high risk for diabetes. An observational study. We measured risk perception during the baseline interview with causal beliefs, perceived susceptibility and perceived controllability. We used logistic regression to examine the relationship between risk perception and attendance. We adjusted for relevant sociodemographic factors, screening results and psychosocial factors. The Hague, the Netherlands. Five hundred and thirty-five Hindustani Surinamese (South Asians) aged 18-60 years from a lifestyle-versus-control intervention for the prevention of diabetes. In total, 68·2% attended the lifestyle or control intervention. Participants perceived lifestyle and heredity to increase the risk of diabetes and perceived increasing physical activity to decrease it. Only 44·2% of the participants perceived themselves as susceptible to diabetes and only those who perceived a family history of diabetes as a cause of diabetes appeared to be more inclined to attend. However, after adjustment for confounding, the association was not statistically significant. Risk perception was not significantly associated with attendance. The results suggest that increasing the risk perception alone in this South Asian population is unlikely to increase the attendance at a diabetes prevention programme.

The black-chinned tilapia Sarotherodon melanotheron is a marine teleost characterised by an extreme euryhalinity. However, beyond a certain threshold at very high salinity, the species exhibits impaired growth and precocious reproduction. In this study, the relationships between reproductive parameters, environmental salinity and condition factor were investigated in wild populations of this species that were sampled in two consecutive years (2003 and 2004) from three locations in Senegal with different salinities: Guiers lake (freshwater, 0 psu), Hann bay (seawater, 37 psu) and Saloum estuary (hypersaline water, 66–127 psu). The highest absolute fecundity and spawning weight were recorded in seawater by comparison to either freshwater or hypersaline water whereas the poorest condition factors were observed in the most saline sampling site. These results reflect higher resource allocation to the reproduction due to the lowest costs of adaptation to salinity in seawater (the natural environment of this species) rather than differences in food resources at sites and/or efficiency at foraging and prey availability. Fecundities, oocyte size as well as spawning weight were consistent from year to year. However, the relative fecundity in the Saloum estuary varied significantly between the dry and rainy raisons with higher values in the wet season, which seems to reflect seasonal variations in environmental salinity. Such a reproductive tactic of producing large amounts of eggs in the rainy season when the salinity in the estuary was lower, would give the fry a better chance at survival and therefore assures a high larval recruitment. An inverse correlation was found between relative fecundity and oocyte size at the two extreme salinity locations, indicating that S. melanotheron has different reproductive strategies in these ecosystems. The adaptive significance of these two reproductive modes is discussed in regard to the heavy osmotic constraint imposed by extreme

Experimental and Computational Studies on the Scattering of an Edge-Guided Wave by a Hidden Crack on a Racecourse Shaped Hole.

Reliable and quantitative non-destructive evaluation for small fatigue cracks, in particular those in hard-to-inspect locations, is a challenging problem. Guided waves are advantageous for structural health monitoring due to their slow geometrical decay of amplitude with propagating distance, which is ideal for rapid wide-area inspection. This paper presents a 3D laser vibrometry experimental and finite element analysis of the interaction between an edge-guided wave and a small through-thickness hidden edge crack on a racecourse shaped hole that occurs, in practice, as a fuel vent hole. A piezoelectric transducer is bonded on the straight edge of the hole to generate the incident wave. The excitation signal consists of a 5.5 cycle Hann-windowed tone burst of centre frequency 220 kHz, which is below the cut-off frequency for the first order Lamb wave modes (SH1). Two-dimensional fast Fourier transformation (2D FFT) is applied to the incident and scattered wave field along radial lines emanating from the crack mouth, so as to identify the wave modes and determine their angular variation and amplitude. It is shown experimentally and computationally that mid-plane symmetric edge waves can travel around the hole's edge to detect a hidden crack. Furthermore, the scattered wave field due to a small crack length, a , (compared to the wavelength λ of the incident wave) is shown to be equivalent to a point source consisting of a particular combination of body-force doublets. It is found that the amplitude of the scattered field increases quadratically as a function of a/λ , whereas the scattered wave pattern is independent of crack length for small cracks a < λ . This study of the forward scattering problem from a known crack size provides a useful guide for the inverse problem of hidden crack detection and sizing.

Scylla paramamosain (Crustacea: Decapoda: Portunidae: Syclla De Hann) is a commercially important mud crab distributed along the coast of southern China and other Indo-Pacific countries (Lin Z, Hao M, Zhu D, et al, Comp Biochem Physiol B Biochem Mol Biol 208-209:29-37, 2017; Walton ME, Vay LL, Lebata JH, et al, Estuar Coast Shelf Sci 66(3-4):493-500, 2006; Wang Z, Sun B, Zhu F, Fish Shellfish Immunol 67:612-9, 2017). While S. paramamosain is a euryhaline species, a sudden drop in salinity induces a negative impact on growth, molting, and reproduction, and may even cause death. The mechanism of osmotic regulation of marine crustaceans has been recently under investigation. However, the mechanism of adapting to a sudden drop in salinity has not been reported. In this study, transcriptomics analysis was conducted on the gills of S. paramamosain to test its adaptive capabilities over 120 h with a sudden drop in salinity from 23 ‰ to 3 ‰. At the level of transcription, 135 DEGs (108 up-regulated and 27 down-regulated) annotated by NCBI non-redundant (nr) protein database were screened. GO analysis showed that the catalytic activity category showed the most participating genes in the 24 s-tier GO terms, indicating that intracellular metabolic activities in S. paramamosain were enhanced. Of the 164 mapped KEGG pathways, seven of the top 20 pathways were closely related to regulation of the Na + / K + -ATPase. Seven additional amino acid metabolism-related pathways were also found, along with other important signaling pathways. Ion transport and amino acid metabolism were key factors in regulating the salinity adaptation of S. paramamosain in addition to several important signaling pathways.

Crucial to finding and treating the 4 million tuberculosis (TB) patients currently missed by national TB programmes, TB stigma is receiving well-deserved and long-delayed attention at the global level. However, the ability to measure and evaluate the success of TB stigma-reduction efforts is limited by the need for additional tools. At a 2016 TB stigma-measurement meeting held in The Hague, The Netherlands, stigma experts discussed and proposed a research agenda around four themes: 1) drivers: what are the main drivers and domains of TB stigma(s)?; 2) consequences: how consequential are TB stigmas and how are negative impacts most felt?; 3) burden: what is the global prevalence and distribution of TB stigma(s) and what explains any variation? 4): intervention: what can be done to reduce the extent and impact of TB stigma(s)? Each theme was further subdivided into research topics to be addressed to move the agenda forward. These include greater clarity on what causes TB stigmas to emerge and thrive, the difficulty of measuring the complexity of stigma, and the improbability of a universal stigma 'cure'. Nevertheless, these challenges should not hinder investments in the measurement and reduction of TB stigma. We believe it is time to focus on how, and not whether, the global community should measure and reduce TB stigma.

Mental incapacity defenses at the War Crimes Tribunal: questions and controversy.

Following a report from the Secretary General in May 1993, the United Nations Security Council adopted Resolution 827 and its Statute establishing an International War Crimes Tribunal for the Former Yugoslavia (ICTY) located in The Hague, The Netherlands. Although such action has been discussed in the past, this is the first time the international community has established a tribunal to indict and try individuals for war crimes. The crimes had been previously "created" by multilateral international treaties. The ICTY Rules of Procedure and Evidence allowed for "any special defense, including that of diminished or lack of mental responsibility." Precise legal parameters of the defense were not specified. In 1998, a defendant at the ICTY "Celebici" Trial named Esad Landzo raised the defense of diminished mental responsibility. The Celebici Trial Chamber thus became the first legal body to consider reduced mental capacity as it applies to international criminal law. This article is an examination of the application of the affirmative defense of diminished responsibility at the ICTY and relates the process to the need for further definition of mental incapacity defenses at the newly established International Criminal Court (ICC). At the ICC preparatory commission, drafting material elements of crimes was emphasized, with less consideration given to mental elements. That diminished capacity and diminished-responsibility defenses have often confused scholars and practitioners alike is explored in this article with suggestions for further directions.

Anthropogenic iodine-129 in seawater along a transect from the Norwegian coastal current to the North Pole.

Variation in the concentrations of iodine-129 (129I, T1/2=15.7 Myr), a low-level radioactive component of nuclear fuel waste, is documented in surface waters and depth profiles collected during 2001 along a transect from the Norwegian Coastal Current to the North Pole. The surface waters near the Norwegian coast are found to have 20 times higher 129I concentration than the surface waters of the Arctic Ocean. The depth profiles of 129I taken in the Arctic Ocean reveal a sharp decline in the concentration to a depth of about 300-500 m followed by a weaker gradient extending down to the bottom. A twofold increase in the 129I concentration is observed in the upper 1000 m since 1996. Based on known estimates of marine transient time from the release sources (the nuclear reprocessing facilities at La Hague, France, and Sellafield, UK), a doubling in the 129I inventory of the top 1000 m of the Arctic Ocean is expected to occur between the years 2001 and 2006. As 129I of polar mixed layer and Atlantic layer of the Arctic Ocean is ventilated by the East Greenland Current into the Nordic Seas and North Atlantic Ocean, further dispersal and increase of the isotope concentration in these regions will be encountered in the near future.

German flooding of the Pontine Marshes in World War II.

Geissler, Erhard; Guillemin, Jeanne

2010-03-01

The German army's 1943 flooding of the Pontine Marshes south of Rome, which later caused a sharp rise in malaria cases among Italian civilians, has recently been described by historian Frank Snowden as a unique instance of biological warfare and bioterrorism in the European theater of war and, consequently, as a violation of the 1925 Geneva Protocol prohibiting chemical and biological warfare. We argue that archival documents fail to support this allegation, on several counts. As a matter of historical record, Hitler prohibited German biological weapons (BW) development and consistently adhered to the Geneva Protocol. Rather than biological warfare against civilians, the Wehrmacht used flooding, land mines, and the destruction of vital infrastructure to obstruct the Allied advance. To protect its own troops in the area, the German army sought to contain the increased mosquito breeding likely to be caused by the flooding. Italians returning to the Pontine Marshes after the German retreat in 1944 suffered malaria as a result of environmental destruction, which was banned by the 1899 and 1907 Hague Conventions and by subsequent treaties. In contrast, a state's violation of the Geneva Protocol, whether past or present, involves the use of germ weapons and, by inference, a state-level capability. Any allegation of such a serious violation demands credible evidence that meets high scientific and legal standards of proof.

The fissile mass in radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA NC La Hague reprocessing plant is measured by neutron interrogation with the Differential Die-away measurement Technique (DDT). In the next years, old hulls and nozzles mixed with Ion-Exchange Resins will be measured. The ion-exchange resins increase neutron moderation in the matrix, compared to the waste measured in the current process. In this context, the Nuclear Measurement Laboratory (LMN) of CEA Cadarache has studied a matrix effect correction method, based on a drum monitor, namely a 3He proportional counter located insidemore » the measurement cavity. After feasibility studies performed with LMN's PROMETHEE 6 laboratory measurement cell and with MCNPX simulations, this paper presents first experimental tests performed on the industrial ACC (hulls and nozzles compaction facility) measurement system. A calculation vs. experiment benchmark has been carried out by performing dedicated calibration measurements with a representative drum and {sup 235}U samples. The comparison between calculation and experiment shows a satisfactory agreement for the drum monitor. The final objective of this work is to confirm the reliability of the modeling approach and the industrial feasibility of the method, which will be implemented on the industrial station for the measurement of historical wastes.

To present the effects of a relatively modest environmental intervention on biological cardiovascular risk indicators. A controlled trial, including two worksites. Measurements (i.e., body composition, blood pressure and serum cholesterol) took place at baseline and at 3- and 12-month follow-up. The 12-month environmental intervention (The Hague, The Netherlands, 2004) consisted of: a 'Food'-part: to stimulate healthier food choices by means of product information in the canteen, and a 'Steps'-part: focused on stimulating stair use by means of motivational prompts in staircases and on elevator doors. Significant differences in change between groups (n=540) in favor of the intervention group were found on: [1] total cholesterol for women (-0.35 mmol/l); [2] HDL for men at 3 months (0.05 mmol/l) and 12 months (0.10 mmol/l); and [3] the total-HDL ratio for the total intervention group at 3 and 12 months (-0.45 mmol/l). Both groups showed a decrease in all body composition values at both follow-ups. A significant difference in change in systolic BP was found in favor of the control group (approximately 4 mm Hg), due to an increase in the intervention group at both follow-ups. Based on the contrasting results, this modest environmental intervention was ineffective in reducing cardiovascular risk in a population of office workers.

This paper presents a research project in The Netherlands in which several SMEs collaborated to create a 3D model of the National spatial planning information. This 2D information system described in the IMRO data standard holds implicit 3D information that can be used to generate an explicit 3D model. The project realized a proof of concept to generate a 3D spatial planning model. The team used the model to integrate it with several 3D Building Information Models (BIMs) described in the open data standard Industry Foundation Classes (IFC). Goal of the project was (1) to generate a 3D BIM model from spatial planning information to be used by the architect during the early design phase, and (2) allow 3D checking of building permits. The team used several technologies like CityGML, BIM clash detection and GeoBIM to explore the potential of this innovation. Within the project a showcase was created with a part of the spatial plan from the city of The Hague. Several BIM models were integrated in the 3D spatial plan of this area. A workflow has been described that demonstrates the benefits of collaboration between the spatial domain and the AEC industry in 3D. The research results in a showcase with conclusions and considerations for both national and international practice.

In order to bring about implementation of routine screening for psychosis risk, a brief version of the Prodromal Questionnaire (PQ; Loewy et al., 2005) was developed and tested in a general help-seeking population. We assessed a consecutive patient sample of 3533 young adults who were help-seeking for nonpsychotic disorders at the secondary mental health services in the Hague with the PQ. We performed logistic regression analyses and CHi-squared Automatic Interaction Detector decision tree analysis to shorten the original 92 items. Receiver operating characteristic curves were used to examine the psychometric properties of the PQ-16. In the general help-seeking population, a cutoff score of 6 or more positively answered items on the 16-item version of the PQ produced correct classification of Comprehensive Assessment of At-Risk Mental State (Yung et al., 2005) psychosis risk/clinical psychosis in 44% of the cases, distinguishing Comprehensive Assessment of At-Risk Mental States (CAARMS) diagnosis from no CAARMS diagnosis with high sensitivity (87%) and specificity (87%). These results were comparable to the PQ-92. The PQ-16 is a good self-report screen for use in secondary mental health care services to select subjects for interviewing for psychosis risk. The low number of items makes it quite appropriate for screening large help-seeking populations, thus enhancing the feasibility of detection and treatment of ultra high-risk patients in routine mental health services.

Ethnic inequalities in health in Western societies are well-documented but poorly understood. We examined associations between health locus of control (HLC) and depressive symptoms among native and non-native Dutch people in the Netherlands. We used hierarchical multiple linear regression analyses on a representative sample of the multi-ethnic population of Amsterdam and The Hague (n = 10,302). HLC was measured with the multidimensional health locus of control scale. Depressive symptoms were measured with the Kessler Psychological Distress scale. Multivariate analyses showed that HLC contributes to ethnic differences in the prevalence of depressive symptoms. Respondents who scored high on external locus of control (PHLC) were more likely to have depressive symptoms than those with a low score on PHLC (β = 0.133, p < 0.001). Conversely, respondents scoring high on internal locus of control (IHLC) were less likely to have depressive symptoms compared to those scoring low on IHLC (β = -0.134, p < 0.001). The associations were most pronounced among Turkish-Dutch and Moroccan-Dutch respondents. Our findings suggest that HLC contributes to ethnic inequalities in depressive symptoms, especially among Turkish and Moroccan ethnic groups. Professionals (e.g. clinicians and policy makers) need to take HLC into account when assessing and treating depression among ethnic minority groups, particularly in Turkish and Moroccan populations. Future research should look further into the associations within these groups.

Based on compressive tests, static on 810 material test system and dynamic on the first compressive loading in split Hopkinson pressure bar (SHPB) tests for Pr-Nd alloy cylinder specimens at high strain rates and temperatures, this study determined a J-C type [G. R. Johnson and W. H. Cook, in Proceedings of Seventh International Symposium on Ballistics (The Hague, The Netherlands, 1983), pp. 541-547] compressive constitutive equation of Pr-Nd alloy. It was recorded by a high speed camera that the Pr-Nd alloy cylinder specimens fractured during the first compressive loading in SHPB tests at high strain rates and temperatures. From highmore » speed camera images, the critical strains of the dynamic shearing instability for Pr-Nd alloy in SHPB tests were determined, which were consistent with that estimated by using Batra and Wei's dynamic shearing instability criterion [R. C. Batra and Z. G. Wei, Int. J. Impact Eng. 34, 448 (2007)] and the determined compressive constitutive equation of Pr-Nd alloy. The transmitted and reflected pulses of SHPB tests for Pr-Nd alloy cylinder specimens computed with the determined compressive constitutive equation of Pr-Nd alloy and Batra and Wei's dynamic shearing instability criterion could be consistent with the experimental data. The fractured Pr-Nd alloy cylinder specimens of compressive tests were investigated by using 3D supper depth digital microscope and scanning electron microscope.« less

World first in high level waste vitrification - A review of French vitrification industrial achievements

2013-07-01

AREVA has more than 30 years experience in operating industrial HLW (High Level radioactive Waste) vitrification facilities (AVM - Marcoule Vitrification Facility, R7 and T7 facilities). This vitrification technology was based on borosilicate glasses and induction-heating. AVM was the world's first industrial HLW vitrification facility to operate in-line with a reprocessing plant. The glass formulation was adapted to commercial Light Water Reactor fission products solutions, including alkaline liquid waste concentrates as well as platinoid-rich clarification fines. The R7 and T7 facilities were designed on the basis of the industrial experience acquired in the AVM facility. The AVM vitrification process wasmore » implemented at a larger scale in order to operate the R7 and T7 facilities in-line with the UP2 and UP3 reprocessing plants. After more than 30 years of operation, outstanding record of operation has been established by the R7 and T7 facilities. The industrial startup of the CCIM (Cold Crucible Induction Melter) technology with enhanced glass formulation was possible thanks to the close cooperation between CEA and AREVA. CCIM is a water-cooled induction melter in which the glass frit and the waste are melted by direct high frequency induction. This technology allows the handling of highly corrosive solutions and high operating temperatures which permits new glass compositions and a higher glass production capacity. The CCIM technology has been implemented successfully at La Hague plant.« less

MOA: Magnetic Field Oscillating Amplified Thruster and its Application for Nuclear Electric and Thermal Propulsion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Frischauf, Norbert; Hettmer, Manfred; Grassauer, Andreas

More than 60 years after the later Nobel laureate Hannes Alfven had published a letter stating that oscillating magnetic fields can accelerate ionised matter via magneto-hydrodynamic interactions in a wave like fashion, the technical implementation of Alfven waves for propulsive purposes has been proposed, patented and examined for the first time by a group of inventors. The name of the concept, utilising Alfven waves to accelerate ionised matter for propulsive purposes, is MOA - Magnetic field Oscillating Amplified thruster. Alfven waves are generated by making use of two coils, one being permanently powered and serving also as magnetic nozzle, themore » other one being switched on and off in a cyclic way, deforming the field lines of the overall system. It is this deformation that generates Alfven waves, which are in the next step used to transport and compress the propulsive medium, in theory leading to a propulsion system with a much higher performance than any other electric propulsion system. Based on computer simulations, which were conducted to get a first estimate on the performance of the system, MOA is a highly flexible propulsion system, whose performance parameters might easily be adapted, by changing the mass flow and/or the power level. As such the system is capable to deliver a maximum specific impulse of 13116 s (12.87 mN) at a power level of 11.16 kW, using Xe as propellant, but can also be attuned to provide a thrust of 236.5 mN (2411 s) at 6.15 kW of power. While space propulsion is expected to be the prime application for MOA and is supported by numerous applications such as Solar and/or Nuclear Electric Propulsion or even as an 'afterburner system' for Nuclear Thermal Propulsion, other terrestrial applications can be thought of as well, making the system highly suited for a common space-terrestrial application research and utilisation strategy.

Child maltreatment is a major social problem with many adverse consequences, and a substantial number of maltreated children are not identified by health care professionals. In 2010, in order to improve the identification of maltreated children in hospitals, a new hospital-based policy was developed in Amsterdam, The Netherlands. This policy was adapted from another policy that was developed in The Hague, the Netherlands, in 2007. In the new Amsterdam policy, all adults presenting at the emergency department due to domestic violence, substance abuse, and/or a suicide attempt are asked whether they have any children in their care. If this is the case, parents are urged to visit the outpatient pediatric department together with all of their children. During this visit, problems are evaluated and voluntary referrals can be arranged to different care organizations. If parents refuse to cooperate, their children are reported to the Dutch Child Abuse Counseling and Reporting Centre. The two aims of this study are to describe (1) characteristics of the identified families and (2) the referrals made to different voluntary and involuntary care organizations during the first 2 years after implementation of the policy. Data were collected from medical records. One hundred and six children from 60 households were included, of which 68 children because their mother was a victim of domestic violence. Referrals to care organizations were arranged for 99 children, of which 67 on a voluntary basis. The Amsterdam policy seems successful in arranging voluntary support for the majority of identified children.

Marine radioactivity in the Arctic: a retrospect of environmental studies in Greenland waters with emphasis on transport of 90Sr and 137Cs with the East Greenland Current.

The waters around Greenland have received radioactive contamination from three major sources: Global fallout, discharges from the nuclear fuel reprocessing plant Sellafield in the UK, and the Chernobyl accident in the Former Soviet Union (FSU). The global fallout peaked in the early 1960s. The radiologically most important radionuclides from this source are 90Sr and 137Cs. The input of global fallout to arctic waters was direct deposition from the atmosphere and indirect delivery through river run off and advection from the Atlantic Ocean via the north-east Atlantic current system. The waterborne discharges from Sellafield which were at their peak between 1974 and 1981 contributed primarily 137Cs, although some 90Sr was also discharged. The Chernobyl accident in 1986 was characterised by its substantial atmospheric release of radiocaesium (134Cs and 137Cs). Other sources may, however, also have contributed to the radioactivity in the Greenland waters. Examples include La Hague, France, and radioactive discharges to the great Siberian rivers (Ob, Yenisey and Lena) from nuclear activities in the Former Soviet Union or the local fallout from the Novaya Zemlya nuclear weapons test site. Dumping of nuclear waste in the Kara and Barents Seas may be another, although minor source. From measurements in Greenland waters carried out since 1962 the transport of radionuclides with the East Greenland Current is calculated and compared with the estimated inputs of 90Sr and 137Cs to the Arctic Ocean. This study focus on 90Sr and 137Cs because the longest time series are available for these two radionuclides.

Lethal Lullabies: A History of Opium Use in Infants.

PubMed

Obladen, Michael

2016-02-01

Poppy extract accompanied the human infant for more than 3 millenia. Motives for its use included excessive crying, suspected pain, and diarrhea. In antiquity, infantile sleeplessness was regarded as a disease. When treatment with opium was recommended by Galen, Rhazes, and Avicenna, baby sedation made its way into early medical treatises and pediatric instructions. Dabbing maternal nipples with bitter substances and drugging the infant with opium were used to hasten weaning. A freerider of gum lancing, opiates joined the treatment of difficult teething in the 17th century. Foundling hospitals and wet-nurses used them extensively. With industrialization, private use was rampant among the working class. In German-speaking countries, poppy extracts were administered in soups and pacifiers. In English-speaking countries, proprietary drugs containing opium were marketed under names such as soothers, nostrums, anodynes, cordials, preservatives, and specifics and sold at the doorstep or in grocery stores. Opium's toxicity for infants was common knowledge; thousands of cases of lethal intoxication had been reported from antiquity. What is remarkable is that the willingness to use it in infants persisted and that physicians continued to prescribe it for babies. Unregulated trade, and even that protected by governments, led to greatly increased private use of opiates during the 19th century. Intoxication became a significant factor in infant mortality. As late as 1912, the International Hague Convention forced governments to implement legislation that effectively curtailed access to opium and broke the dangerous habit of sedating infants. © The Author(s) 2015.

[Suicidal behaviour and attempted suicide occurring during assessment by the outreach psychiatric emergency service].

de Winter, R F P; de Groot, M H; van Dassen, M; Deen, M L; de Beurs, D P

The outreach emergency psychiatric service plays an important role in recognising, arranging interventions and preventing suicide and suicidal behaviour. However, little is known about the assessments that members of the emergency team make when faced with patients showing suicidal behaviour.
AIM: To describe the relationships that are revealed between patient characteristics, suicidal thoughts and attempted suicide during assessments made by the emergency psychiatric service in The Hague.
METHOD: The emergency service kept a detailed record of 14,705 consultations. We compared the characteristics of patients who had suicidal thoughts with those of patients who had no such thoughts and we also compared the characteristics of patients who had attempted to commit suicide with those of patients who had not. We drew these comparisons by using logistic regression models, adjusting for clustering.
RESULTS: 32.2% of the patients showed signs of suicidal behaviour and 9.2 % appeared likely to attempt suicide. Suicidal behaviour occurred most often in patients with depression. Suicidal patients were more often admitted to hospital than were non-suicidal patients and they were more likely to have been referred by a general practitioner or a general hospital. Medication was the most frequent means employed in attempts to commit suicide.
CONCLUSION: In about one third of the consultations of the outreach emergency psychiatric service, the patient showed suicidal behaviour. The actions and the policy of the emergency psychiatric service with regard to suicidal behaviour were diverse and dependent on factors that could change over the course of time.

Waste Estimates for a Future Recycling Plant in the US Based Upon AREVA Operating Experience - 13206

2013-07-01

Estimates of process and secondary wastes produced by a recycling plant built in the U.S., which is composed of a used nuclear fuel (UNF) reprocessing facility and a mixed oxide (MOX) fuel fabrication facility, are performed as part of a U.S. Department of Energy (DOE) sponsored study [1]. In this study, a set of common inputs, assumptions, and constraints were identified to allow for comparison of these wastes between different industrial teams. AREVA produced a model of a reprocessing facility, an associated fuel fabrication facility, and waste treatment facilities to develop the results for this study. These facilities were dividedmore » into a number of discrete functional areas for which inlet and outlet flow streams were clearly identified to allow for an accurate determination of the radionuclide balance throughout the facility and the waste streams. AREVA relied primarily on its decades of experience and feedback from its La Hague (reprocessing) and MELOX (MOX fuel fabrication) commercial operating facilities in France to support this assessment. However, to perform these estimates for a U.S. facility with different regulatory requirements and to take advantage of some technological advancements, such as in the potential treatment of off-gases, some deviations from this experience were necessary. A summary of AREVA's approach and results for the recycling of 800 metric tonnes of initial heavy metal (MTIHM) of LWR UNF per year into MOX fuel under the assumptions and constraints identified for this DOE study are presented.

Most of anthropogenic 129I in marine environment are due to discharge from the nuclear fuel reprocessing facilities at Sellafield (U.K.) and La Hague (France) for past few decades. The discharge raised 129I concentration in seawaters in the North Atlantic and Arctic Oceans to more than 109 atoms L-1, which is two orders of magnitude higher than that in other region. Recently, in March 2011, a large quantity of 129I was released into the western North Pacific due to the Fukushima Daiichi Nuclear Power Plant (F1NPP) accident. To evaluate the influence of these events, we have measured 129I concentration in seawaters in the northern North Pacific Ocean, Bering and Chukchi Seas, and Arctic Ocean in 2012-2013. The 129I concentrations were 1.0-1.8 × 107 atoms L-1 in the surface waters in the vicinity of 47°N 150°E-130°W North Pacific Ocean, Bering Sea, and Chukchi Sea (<74°N), which are equal to or lower than the 129I concentration level in surface water in the North Pacific Ocean before the F1NPP accident. The vertical profiles in the North Pacific were almost same as that observed in the western North Pacific before the F1NPP accident. The 129I distribution in seawater in the North Pacific to the Chukchi Sea revealed no significant increase of 129I concentration caused by the F1NPP accident. The 129I concentrations were 13-14 × 107 atoms L-1 in surface waters and 80 × 107 atoms L-1 at depths of 300 and 800 m in the Arctic Ocean.

127I and 129I/127I isotopic ratio in marine alga Fucus virsoides from the North Adriatic Sea.

The only stable iodine isotope is 127I and the natural 129I/127I ratio in the biosphere has increased from 10(-15)-10(-14) to 10(-10)-10(-9), mainly due to emissions from nuclear fuel reprocessing plants. In Europe they are located at La Hague (France) and Sellafield (England), where the ratio of 129I/127I is up to 10(-4). The marine environment, i.e. the oceans, is the major source of iodine with average concentrations of around 60 mirogL(-1) iodine in seawater. Brown algae accumulate iodine at high levels of up to 1.0% of dry weight, and therefore they are an ideal bioindicator for studying the levels of 127I and 129I in the marine environment. A radiochemical neutron activation analysis (RNAA) method, developed at our laboratory, was used for 129I determination in the brown alga Fucus virsoides (Donati) J. Agardh, and the same technique of RNAA was used for total 127I determination. The samples were collected along the coast of the Gulf of Trieste and the West coast of Istria in the North Adriatic Sea in the period from 2005 to 2006. Values of the 129I/127I ratio up to 10(-9) were found, which is in agreement with the present average global distribution of 129I. The levels of stable iodine found were in the range from 235 to 506 microg g(-1) and the levels of 129I from 1.7 to 7.3 x 10(-3)Bq kg(-1) (2.6-10.9 x 10(-7) microg g(-1)), on a dry matter basis.

Some of the contents of this paper have been previously presented at the 16th Annual Meeting of the International Society for Technology Assessment in Health Care June 20, 2000 in the Hague, Netherlands and at the 21st Annual Meeting of the Society for Medical Decision Making as a poster on October 3, 1999 in Reno, NV. Studies of schizophrenia treatment often oversimplify the array of health outcomes among patients. Our objective was to derive a set of disease states for schizophrenia using the Positive and Negative Symptom Assessment Scale (PANSS) that captured the heterogeneity of symptom responses. Using data from a 1-year clinical trial that collected PANSS scores and costs on schizophrenic patients (N=663), we conducted a k-means cluster analyses on PANSS scores for items in five factor domains. Results of the cluster analysis were compared with a conceptual framework of disease states developed by an expert panel. Final disease states were defined by combining our conceptual framework with the empirical results. We tested its utility by examining the influence of disease state on treatment costs and prognosis. Analyses led to an eight-state framework with varying levels of positive, negative, and cognitive impairment. The extent of hostile/aggressive symptoms and mood disorders correlated with severity of disease states. Direct treatment costs for schizophrenia vary significantly across disease states (F=27.47, df=7, p<0.0001), and disease state at baseline was among the most important predictors of treatment outcomes. The disease states we describe offer a useful paradigm for understanding the links between symptom profiles and outcomes.

Tritium ( 3 H) is mainly released into the environment by nuclear power plants, military nuclear facilities and nuclear reprocessing plants. The construction of new nuclear facilities in the world as well as the evolution of nuclear fuel management might lead to an increase of 3 H discharges from the nuclear industry. The VATO project was set up by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) and EDF (Electricité de France) to reduce the uncertainties in the knowledge about transfers of 3 H from an atmospheric source (currently releasing HT and HTO) to a grassland ecosystem. A fully instrumented technical platform with specifically designed materials was set up downwind of the AREVA NC La Hague reprocessing plant (Northwest of the France). This study, started in 2013, was conducted in four main steps to provide an hourly data set of 3 H concentrations in the environment, adequate to develop and/or validate transfer models. It consisted first in characterizing the physico-chemical forms of 3 H present in the air around the plant. Then, 3 H transfer kinetics to grass were quantified regarding contributions from various compartments of the environment. For this purpose, an original experimental procedure was provided to take account for biases due to rehydration of freeze-dried samples for the determination of OBT activity concentrations in biological samples. In a third step, the 3 H concentrations measured in the air and in rainwater were reconstructed at hourly intervals. Finally, a data processing technique was used to determine the biological half-lives of OBT in grass. Copyright © 2016 Elsevier Ltd. All rights reserved.

The present study examined the relation between two different acculturation measures (i.e., linguistic acculturation and the acculturation strategies integration, separation and marginalization) and past year cannabis use. Additionally, we studied the mediating role of affiliation with cannabis-using peers. Data were utilized from i4culture, a Dutch study on immigrant adolescents and young adults aged 15-24 years. Participants belonged to the five largest immigrant populations in the Netherlands, living in or around the four major Dutch cities: Amsterdam, the Hague, Rotterdam, and Utrecht. In total, 771 adolescents and young adults (mean age 19.29, SD=2.61, 53.8% female) from Surinamese (n=210, 27.2%), Moroccan (n=209, 27.1%), Turkish (n=110, 14.3%), Antillean (n=109, 14.1%), and Asian (n=133, 17.3%) backgrounds participated. With questionnaires, past year cannabis use, acculturation strategy, linguistic acculturation, and affiliation with cannabis-using peers were assessed. Using logistic regression analyses, we found no relation between acculturation strategy and past year cannabis use (OR=1.25, p=0.38 for separation vs integration and OR=0.86, p=0.50 for marginalization vs integration). Linguistic acculturation was positively related to cannabis use (OR=2.20, p<0.01). Affiliation with cannabis-using peers partly mediated this relation (OR=1.09, p<0.01). Non-Western immigrant youngsters who speak the host culture's language at home are more likely to use cannabis than youngsters who speak their native language at home. The former group is more likely to affiliate with cannabis-using peers, which partly explains their increased risk of cannabis use. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Nuclear power plants (NPPs) release toxic emissions into the environment that may affect neighboring populations. This ecologic study was designed to investigate the possibility of an excess incidence of cancer in the vicinity of French NPPs by examining the incidence by municipality of 12 types of cancer in the population aged 15 years and older during the 1995-2011 period. Population exposure to pollution was estimated on the basis of distance from towns of residence to the NPP. Using regression models, we assessed the risk of cancer in a 20-km zone around NPPs and observed an excess incidence of bladder cancer (Relative Risk (RR), 95% Credibility Interval (95% CI)) in men and women (RR men  = 1.08; 95% CI: 1.00, 1.17 and RR women  = 1.19; 95% CI: 1.02, 1.39). Women living within the 20-km proximity areas had a significantly reduced risk of thyroid cancer (RR women  = 0.86; 95% CI: 0.77, 0.96). No excess risk of hematologic malignancies in either sex was seen. The higher than expected incidence of bladder cancer may be due to an excess incidence localized around the Flamanville NPP and the nearby La Hague nuclear waste treatment center, which is a source of chemical contaminants, many (including arsenic) of them known risk factors for bladder cancer. Differences in medical practices could explain the reduced risk of thyroid cancer. In this first study of adults living near NPPs in France, cancer incidence is significantly higher than in the references populations for one of the cancer types studied: bladder cancer. © 2017 UICC.

The aim of this cross-sectional study was to investigate the relationship between parental and family-related factors and childhood dental caries in a sample of 5- to 6-year-old children of Dutch, Moroccan and Turkish origin. Furthermore, the relationship of parental and family-related factors with social class and ethnicity was examined. The study sample included 92 parent-child dyads (46 cases and 46 controls), which were recruited from a large paediatric dental centre in The Hague, the Netherlands. Cases were children with four or more decayed, missing or filled teeth, and controls were caries free. Validated questionnaires were used to collect data on sociodemographic characteristics, oral health behaviours, parents' dental self-efficacy and locus of control (LoC), parenting practices and family functioning. Parenting practices were also assessed using structured video observations of parent-child interactions. Parents of controls had a more internal LoC, and they were more likely to show positive (observed) parenting in terms of positive involvement, encouragement and problem-solving, compared to cases (P < 0.05). Lower social class was significantly associated with a lower dental self-efficacy, a more external LoC and poorer parenting practices. Furthermore, LoC was more external in Moroccan and Turkish parents, compared to Dutch parents. Parents' internal LoC and observed positive parenting practices on the dimensions positive involvement, encouragement and problem-solving were important indicators of dental health in children of Dutch, Moroccan and Turkish origin. Findings suggest that these parental factors are potential mediators of socioeconomic inequalities in children's dental health. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Wicked problems and a 'wicked' solution.

PubMed

Walls, Helen L

2018-04-13

'Wicked' is the term used to describe some of the most challenging and complex issues of our time, many of which threaten human health. Climate change, biodiversity loss, persisting poverty, the advancing obesity epidemic, and food insecurity are all examples of such wicked problems. However there is a strong body of evidence describing the solutions for addressing many of these problems. Given that much is known about how many of these problems could be addressed - and given the risks of not acting - what will it take to create the 'tipping point' needed for effective action? A recent (2015) court ruling in The Hague held that the Dutch government's stance on climate change was illegal, ordering them to cut greenhouse gas emissions by at least 25% within 5 years (by 2020), relative to 1990 levels. The case was filed on behalf of 886 Dutch citizens, suing the government for violating human rights and climate changes treaties by failing to take adequate action to prevent the harmful impacts of climate change. This judicial ruling has the potential to provide a way forward, inspiring other civil movements and creating a template from which to address other wicked problems. This judicial strategy to address the need to lower greenhouse gas emissions in the Netherlands is not a magic bullet, and requires a particular legal and institutional setting. However it has the potential to be a game-changer - providing an example of a strategy for achieving domestic regulatory change that is likely to be replicable in some countries elsewhere, and providing an example of a particularly 'wicked' (in the positive, street-slang sense of the word) strategy to address seemingly intractable and wicked problems.

The 'Hague Protocol' enables professionals at the adult Emergency Department (ED) to detect child abuse based on three parental characteristics: (i) suicide attempt or self-harm, (ii) domestic violence or (iii) substance abuse, and to refer them to the Reporting Centre for Child Abuse and Neglect (RCCAN). This study investigates what had happened to the families three months after this referral. ED referrals based on parental characteristics (N = 100) in which child abuse was confirmed after investigation by the RCCAN were analysed. Information was collected regarding type of child abuse, reason for reporting, duration of problems prior to the ED referral, previous involvement of support services or other agencies, re-occurrence of the problems and outcome of the RCCAN monitoring according to professionals and the families. Of the 100 referred cases, 68 families were already known to the RCCAN, the police or family support services, prior to the ED referral. Of the 99 cases where information was available, existing support was continued or intensified in 31, a Child Protection Services (CPS) report had to be made in 24, new support was organized for 27 cases and in 17 cases support was not necessary, because the domestic problems were already resolved. Even though the RCCAN is mandated to monitor all referred families after three months, 31 cases which were referred internally were not followed up. Before referral by the ED two thirds of these families were already known to organizations. Monitoring may help provide a better, more sustained service and prevent and resolve domestic problems. A national database could help to link data and to streamline care for victims and families. We recommend a Randomized Controlled Trial to test the effectiveness of this Protocol in combination with the outcomes of the provided family support. © 2014 John Wiley & Sons Ltd.

Some demographic parameters, the genetic structure and the evolution of the genetic variability of six French meat sheep breeds were analysed in relation with their management. Four of these breeds are submitted to more or less intense selection: the Berrichon du Cher (BCH), Blanc du Massif Central (BMC), Charollais (CHA) and Limousin (LIM); the other two breeds are under conservation: the Roussin de La Hague (RLH) and Solognot (SOL). Genealogical data of the recorded animals born from 1970 to 2000 and of their known ancestors were used. The most balanced contributions of the different flocks to the sire-daughter path was found in the SOL. In the BCH, a single flock provided 43% of the sire-AI sire path, whereas the contributions of the flocks were more balanced in the BMC and LIM (the only other breeds where AI is used to a substantial amount). The distribution of the expected genetic contribution of the founder animals was found to be unbalanced, especially in the BCH and LIM. The effective numbers of ancestors (founders or not) for the ewes born from 1996 to 2000 were equal to 35 (BCH), 144 (BMC), 112 (CHA), 69 (LIM), 40 (RLH) and 49 (SOL). Inbreeding was not analysed in the BMC, due to incomplete pedigree information. From 1980 on, the rates of inbreeding, in percentage points per year, were +0.112 (BCH), +0.045 (CHA), +0.036 (LIM), +0.098 (RLH) and +0.062 (SOL). The implications of the observed trends on genetic variability are discussed in relation to the genetic management of each breed. The need for a larger selection basis in the BCH, the efficiency of the rules applied in the SOL to preserve the genetic variability and the need for a more collective organisation in the CHA and RLH are outlined.

Accelerator mass spectrometry of iodine-129 and its applications in natural water systems

NASA Astrophysics Data System (ADS)

Buraglio, Nadia

During recent decades, huge amount of radioactive waste has been dumped into the earth's surface environments. 129I (T1/2 = 15.6 My) is one of the radioactive products that has been produced through a variety of processes, including atomic weapon testing, reprocessing of nuclear fact and nuclear accidents. This thesis describes development of the Accelerator Mass Spectrometry (AMS) ultra-sensitive atom counting technique at Uppsala Tandem Laboratory to measure 129I and discusses investigations of its distribution in the hydrosphere (marine and fresh water) and precipitation. The AMS technique provides a method for measuring long-lived radioactive isotopes in small samples, relative to other conventional techniques, and thus opens a now line of research. The optimization of the AMS system at Uppsala included testing a time of flight detector, evaluation of the most appropriate charge-state, reduction of molecular interference and improvement of the detection limit. Furthermore, development of a chemical procedure for separation of iodine from natural water samples has been accomplished. The second part of the thesis reports investigations of 129I in natural waters and indicates that high concentrations of 129I (3-4 orders of magnitude higher than in the prenuclear era) are found in most of the considered natural waters. Inventory calculations and results of measurements suggest that the major sources of radioactive iodine are the two main European nuclear reprocessing facilities at Sellafield (U.K.) and La Hague (France). This information provides estimates of the transit time and vertical mixing of water masses in the central Arctic Ocean. Results from precipitation, lakes and runoff are used to elucidate mechanisms of transport of 129I from the point sources and its pathways in the hydrological environment. This study also shows the need for continuous monitoring of the 129I level in the hydrosphere and of its future variability.

A radiological assessment has been carried out considering discharges of radioactivity to the Baltic Sea marine environment since 1950. The sources of radioactivity that have been evaluated are atmospheric nuclear-weapons fallout, fallout from the Chernobyl accident in 1986, discharges of radionuclides from Sellafield and La Hague transported into the Baltic Sea, and discharges of radionuclides from nuclear installations located in the Baltic Sea area. Dose rates from man-made radioactivity to individual members of the public (critical groups) have been calculated based on annual intake of seafood and beach occupancy time. The dose rates to individuals from the regions of the Bothnian Sea and Gulf of Finland are predicted to be larger than from any other area in the Baltic Sea due to the pattern of Chernobyl fallout. The dose rates are predicted to have peaked in 1986 at a value of 0.2 mSv year-1. Collective committed doses to members of the public have been calculated based on fishery statistics and predicted concentrations of radionuclides in biota and coastal sediments. The total collective dose from man-made radioactivity in the Baltic Sea is estimated at 2600 manSv, of which approximately two-thirds originate from Chernobyl fallout, approximately one-quarter from atmospheric nuclear-weapons fallout, approximately 8% from European reprocessing facilities, and approximately 0.04% from nuclear installations bordering the Baltic Sea area. An assessment of small-scale dumping of low-level radioactive waste in the Baltic Sea in the 1960s by Sweden and the Soviet Union has showed that doses to man from these activities are negligible. Dose rates and doses from natural radioactivity dominate except for the year 1986 where dose rates to individuals from Chernobyl fallout in some regions of the Baltic Sea approached those from natural radioactivity.

Frederik Ruysch's Fascination With Urolithiasis

Frederik Ruysch was born on March 23, 1638, in The Hague, and studied at the University of Leiden, where he graduated in 1664. He married a daughter of a famous architect and became a praelector of the Amsterdam surgeon's guild in 1665. In 1666, his rise continued, as he became elected as the Professor of the Anthenaeum Illustre. In 1668, Ruysch became the chief instructor to the midwives and by 1679 was the forensics advisor to Amsterdam's courts. His anatomical knowledge was second to none, and he gained worldwide notoriety for his discovery of the valves in lymphatics and the vomeronasal organ. Ruysch was keenly interested in dissection and anatomy, and developed his own methods for preservation of specimens. His secret was called liquor balsamicum. Over 300 years ago, Ruysch developed all of his talents to the point of creating a menagerie, of sorts, out of his specimens. The popularity of his rather morbid exhibits attracted such dignitaries as Peter The Great in 1697. Ruysch had several children from his marriage, and his daughter Rachel helped him illustrate many of his collections. Frederik Ruysch became an intriguing historical figure, worthy of some attention at kidney stone meetings, precisely because he chose these concretions to serve as one of the "finishing elements" in several of his collections. The purpose of this presentation is to present to a knowledgeable stone group, the artistic license of one of the first entrepreneurial surgeons and anatomists of the 17th century. Ruysch was a skilled surgeon, obstetrician, and anatomist, keenly interested in the science of anatomy, especially infant and fetal anatomy. In addition, he exhibited his fine collection of urinary stones in a rather unique way, in his "anatomical pieces."

Chemical interaction matrix between reagents in a Purex based process

The United States Department of Energy (DOE) is the responsible entity for the disposal of the United States excess weapons grade plutonium. DOE selected a PUREX-based process to convert plutonium to low-enriched mixed oxide fuel for use in commercial nuclear power plants. To initiate this process in the United States, a Mixed Oxide (MOX) Fuel Fabrication Facility (MFFF) is under construction and will be operated by Shaw AREVA MOX Services at the Savannah River Site. This facility will be licensed and regulated by the U.S. Nuclear Regulatory Commission (NRC). A PUREX process, similar to the one used at La Hague,more » France, will purify plutonium feedstock through solvent extraction. MFFF employs two major process operations to manufacture MOX fuel assemblies: (1) the Aqueous Polishing (AP) process to remove gallium and other impurities from plutonium feedstock and (2) the MOX fuel fabrication process (MP), which processes the oxides into pellets and manufactures the MOX fuel assemblies. The AP process consists of three major steps, dissolution, purification, and conversion, and is the center of the primary chemical processing. A study of process hazards controls has been initiated that will provide knowledge and protection against the chemical risks associated from mixing of reagents over the life time of the process. This paper presents a comprehensive chemical interaction matrix evaluation for the reagents used in the PUREX-based process. Chemical interaction matrix supplements the process conditions by providing a checklist of any potential inadvertent chemical reactions that may take place. It also identifies the chemical compatibility/incompatibility of the reagents if mixed by failure of operations or equipment within the process itself or mixed inadvertently by a technician in the laboratories.

Older patients are believed to prefer a more passive role in treatment decision making, but studies reporting this relation were conducted over a decade ago or were retrospective. We prospectively compared younger (40-64 years) versus older (≥ 65 years) breast cancer patients' preferences for decision-making roles and their perceived actual roles. A prospective multicenter study was conducted in Leiden, The Hague, and Tilburg over a 2-year period. Early-stage breast cancer patients were surveyed about their preferred and perceived decision-making roles (active, shared, or passive) concerning surgery type (breast-conserving vs. mastectomy) (n = 74), adjuvant chemotherapy (aCT, n = 43), and adjuvant hormonal therapy (aHT, n = 39). For all decisions, both age groups most frequently preferred a shared role before consultation, except for decisions about aHT, for which younger patients more commonly preferred an active role. The proportion of patients favoring an active or passive role in each decision was lower for the older than the younger patients, but none of the differences was significant. Regarding perceived actual roles, both groups most frequently reported an active role in the surgical decision after consultation. In deciding about both aCT and aHT, a larger proportion of older patients perceived having had a passive role compared to younger patients, and a greater proportion of younger patients perceived having been active. Again, differences were not statistically significant. Most older patients preferred to decide together with their clinician, but preferences varied widely. Older patients more often than younger patients perceived they had not been involved in decisions about systemic therapy. Clinicians should invite all patients to participate in decision making and elicit their preferred role. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Functional consequences of hemispherectomy.

Using the International Classification of Functioning Disability and Health (ICF) (WHO, 2001), impairments, activities and social participation are reported in 12 children (mean age at surgery 5.9 years) who were investigated before and three times over a 2-year period after hemispherectomy. Impairments were assessed (i) in terms of seizure frequency (Engel classification) and seizure severity (HASS) and (ii) with respect to muscle strength (MRC), range of motion (JAM score) and muscle tone (modified Ashworth scale). Activities were assessed in terms of gross motor functioning (GMFM) and self-care, mobility and social function (PEDI). Participation was assessed in terms of epilepsy-related restrictions and quantified by means of the Hague Restrictions in Childhood Epilepsy Scale (HARCES). Nine out of 12 children could be classified as free of seizures (Engel class I), and in the remaining three seizure frequency was Engel class III. HASS scores showed maximum improvement in 10 out of 12 children and near-maximum improvement in the two remaining children. Muscle strength and muscle tone on the side of the body contralateral to the hemispherectomy, which were already decreased preoperatively, decreased even further in the first 6 months after surgery, but returned to the presurgical baseline thereafter, except for the distal part of the arm. Range of motion was abnormal prior to operation and remained so after operation. Mean GMFM increase was 20% after 2 years (95% confidence interval 10-33); all five dimensions improved statistically significantly (P < 0.05). Mean PEDI increase was more than 20 scale points (95% confidence interval 10-35); again, all domains improved significantly (P < 0.05). In nearly all children, HARCES scores had normalized 2 years after surgery. In conclusion, decrease of seizure frequency and severity widens the scope of motor and social functioning, which overrides the effects of remaining motor impairments.

The use of forensic botany and geology in war crimes investigations in NE Bosnia.

Brown, A G

From 1997 to 2002 the United Nations International Criminal Tribune for the former Yugoslavia (ICTY) undertook the exhumation of mass graves in NE Bosnia as part of the war crimes investigations aimed at providing evidence for the prosecution of war criminals in The Hague. This involved the location and exhumation of seven former mass graves (primary sites) dug following the fall of Srebrenica in July 1995. These primary mass graves were secretly and hurriedly exhumed three months later and most of the bodies or body parts transported and reburied in a large number of secondary sites many of which were subsequently exhumed by ICTY. The aim of the pollen and soil/sediment studies was to provide an 'environmental profile' of the original site of the samples and use this to match the relocated bodies to the original mass graves. This was part of completing the chain of evidence, providing evidence of the scale and organization of the original atrocities and the subsequent attempts to conceal the evidence related to them. All the primary sites were located in areas of contrasting geology, soils and vegetation, and this allowed matching of the sediment transported in intimate contact with the bodies to the original burial sites, which in some cases were also the execution sites. In all, over 24 sites were investigated, over 240 samples collected and analyzed under low power microscopy and 65 pollen sub-samples fully analyzed. The pollen and sediment descriptions were used in conjunction with the mineralogy (using XRD) of primary and secondary sites in order to provide matches. These matches were then compared with matching evidence from ballistic studies and clothing. The evidence has been used in court and is now in the public domain. It is believed this is the first time 'environmental profiling' techniques have been used in a systematic manner in a war crimes investigation.

Galileo Probe Mass Spectrometer Measurements of the Chemical Composition of the Atmosphere of Jupiter

The chemical and isotopic composition of the Jovian atmosphere was measured by the Galileo Probe Mass Spectrometer (GPMS). This data was obtained on December 7, 1995 over a time period of approximately 1 hour during the probe descent in the 0.5 to 20 bar pressure region and transmitted to Earth over a period of several weeks. The sampling was either of atmospheric gases directly introduced into the ion source of the mass spectrometer through one of 2 capillary leak arrays or of gas which had been processed in enrichment cells to enhance the sensitivity of the measurement to trace species or heavy noble gases. Mixing ratios or limits were previously reported [Niemann et al., 1996] for atmospheric hydrogen, helium, methane, water, ammonia, hydrogen sulfide, neon, argon, krypton, and xenon. Ratios for isotopes of He, Ne, Ar, Kr, Xe, C, and H were also obtained. Additional molecules detected at the present stage of analysis include ethane, ethylene, propane, and hydrogen chloride as well as benzene and carbon/nitrogen compounds. The GPMS Flight Unit was not calibrated for some of these molecules and laboratory studies continue on an Engineering Unit. A substantial increase was observed in the mixing ratio of water, hydrogen sulfide, ethane and other species with increasing depth into the atmosphere over the 8 bar to 23 bar pressure regime. It has been suggested [Atreya et al., 1996] that the lower than expected abundance of many species in the early part of the descent and the observed increase with depth may be the signature of a large downdraft.

Essentials Literature on socioeconomic status (SES) and incidence of venous thromboembolism (VTE) is scarce. We assessed neighborhood SES with VTE risk in a population of over 1.4 million inhabitants. Higher neighborhood SES was associated with lower incidence of VTE. These findings are helpful to inform policy and resource allocation in health systems. Background The association between socioeconomic status and arterial cardiovascular disease is well established. However, despite its high burden of disability-adjusted life years, little research has been carried out to determine whether socioeconomic status is associated with venous thromboembolism. Objective To determine if neighborhood socioeconomic status is associated with venous thromboembolism in a population-based study from the Netherlands. Methods We identified all patients aged 15 years and older with a first event of venous thromboembolism from inhabitants who lived in the urban districts of The Hague, Leiden and Utrecht in the Netherlands in 2008-2012. Neighborhood socioeconomic status was based on the status score, which combines educational level, income and unemployment on a four-digit postal code level. Incidence rate ratios of venous thromboembolism were calculated for different levels of neighborhood socioeconomic status, with adjustments for age and sex. Results A total of 7373 patients with a first venous thromboembolism (median age 61 years; 50% deep vein thrombosis) were identified among more than 1.4 million inhabitants. Higher neighborhood SES was associated with lower incidence of VTE. In the two highest status score groups (i.e. the 95-99th and > 99th percentile), the adjusted incidence rate ratios were 0.91 (95% confidence interval [CI], 0.84-1.00) and 0.80 (95% CI, 0.69-0.93), respectively, compared with the reference status score group (i.e. 30-70th percentile). Conclusions High neighborhood socioeconomic status is associated with a lower risk of first venous thromboembolism. © 2017

SPA- STATISTICAL PACKAGE FOR TIME AND FREQUENCY DOMAIN ANALYSIS

NASA Technical Reports Server (NTRS)

Brownlow, J. D.

1994-01-01

The need for statistical analysis often arises when data is in the form of a time series. This type of data is usually a collection of numerical observations made at specified time intervals. Two kinds of analysis may be performed on the data. First, the time series may be treated as a set of independent observations using a time domain analysis to derive the usual statistical properties including the mean, variance, and distribution form. Secondly, the order and time intervals of the observations may be used in a frequency domain analysis to examine the time series for periodicities. In almost all practical applications, the collected data is actually a mixture of the desired signal and a noise signal which is collected over a finite time period with a finite precision. Therefore, any statistical calculations and analyses are actually estimates. The Spectrum Analysis (SPA) program was developed to perform a wide range of statistical estimation functions. SPA can provide the data analyst with a rigorous tool for performing time and frequency domain studies. In a time domain statistical analysis the SPA program will compute the mean variance, standard deviation, mean square, and root mean square. It also lists the data maximum, data minimum, and the number of observations included in the sample. In addition, a histogram of the time domain data is generated, a normal curve is fit to the histogram, and a goodness-of-fit test is performed. These time domain calculations may be performed on both raw and filtered data. For a frequency domain statistical analysis the SPA program computes the power spectrum, cross spectrum, coherence, phase angle, amplitude ratio, and transfer function. The estimates of the frequency domain parameters may be smoothed with the use of Hann-Tukey, Hamming, Barlett, or moving average windows. Various digital filters are available to isolate data frequency components. Frequency components with periods longer than the data collection interval

Permafrost cannot be directly detected from space, but many surface features of permafrost terrains and typical periglacial landforms are observable with a variety of EO sensors ranging from very high to medium resolution at various wavelengths. In addition, landscape dynamics associated with permafrost changes and geophysical variables relevant for characterizing the state of permafrost, such as land surface temperature or freeze-thaw state can be observed with space-based Earth Observation. Suitable regions to examine environmental gradients across the Arctic have been defined in a community white paper (Bartsch et al. 2014). These transects have been updated within the ESA DUE GlobPermafrost project. The ESA DUE GlobPermafrost project develops, validates and implements Earth Observation (EO) products to support research communities and international organisations in their work on better understanding permafrost characteristics and dynamics. Prototype product cases will cover different aspects of permafrost by integrating in situ measurements of subsurface properties and surface properties, Earth Observation, and modelling to provide a better understanding of permafrost today. The project will extend local process and permafrost monitoring to broader spatial domains, support permafrost distribution modelling, and help to implement permafrost landscape and feature mapping in a GIS framework. It will also complement active layer and thermal observing networks. Both lowland (latitudinal) and mountain (altitudinal) permafrost issues are addressed. The selected transects and first results will be presented. This includes identified needs from the user requirements survey, a review of existing land surface products available for the Arctic as well as prototypes of GlobPermafrost datasets, and the permafrost information system through which they can be accessed.

The TV broadcast discusses problems of the modernization of the Romanian astronomical infrastructure, the worst in Eastern Europe. It presents the TELEROM project which proposed to establish a new EU-funded robotic 1,3 m telescope, a project finally rejected by the Astronomical Institute of the Romanian Academy mainly due to the incompetence of the director of this Institute, Dr. Vasile Mioc. It is mentioned that this was the second very promising project failed under the same director, after the project ASTEROS in value of 15 million Euro to establish two modern telescopes was also lost in the recent years. The total cost of the TELEROM project was 1,5 million Euro, according to the agreement with the EU foundation for Regional Development (director Hanns Ruder Institut für Theoretische Astrophysik, Universität Tübingen, Germany - the TELEROM auto-dimissed project director). The facilities from this implementation were very promising in observations of Solar system objects (asteroids, near Earth asteroids, comets), few hundred millions of faint stars, quasars, exoplanets and galaxies. Initially, the director Vasile Mioc and the governing body of the Romanian Astronomical Institute intended to place the telescope in Romania in very bad astroclimatic conditions, namely in the old Feleac observatory, very close to the very highly polluted and quite clouded city of Cluj-Napoca. Many opposite considerations (Dr. Marian Doru Suran from Bucharest, many Romanian astronomers from the Diaspora and a group of 68 astronomers, professors, public outreach people and students from Romania and Diaspora supporting TELEROM) were totally disregarded! Due to refuse to place the telescope in very good astroclimatic conditions (in Canary Islands or Chile) and also due to the impossibility to establish a decent national astronomical observatory in Romania by the direction of the Institute in agreement with the State body of Romania ("Academia Romana" and "Autoritatea Nationala pentru

AREVA NC is preparing to process, characterize and compact old used fuel metallic waste stored at La Hague reprocessing plant in view of their future storage ("Haute Activité Oxyde" HAO project). For a large part of these historical wastes, the packaging is planned in CSD-C canisters ("Colis Standard de Déchets Compacté s") in the ACC hulls and nozzles compaction facility ("Atelier de Compactage des Coques et embouts"). . This paper presents a new method to take into account the possible presence of fissile material clusters, which may have a significant impact in the active neutron interrogation (Differential Die-away Technique) measurement of the CSD-C canisters, in the industrial neutron measurement station "P2-2". A matrix effect correction has already been investigated to predict the prompt fission neutron calibration coefficient (which provides the fissile mass) from an internal "drum flux monitor" signal provided during the active measurement by a boron-coated proportional counter located in the measurement cavity, and from a "drum transmission signal" recorded in passive mode by the detection blocks, in presence of an AmBe point source in the measurement cell. Up to now, the relationship between the calibration coefficient and these signals was obtained from a factorial design that did not consider the potential for occurrence of fissile material clusters. The interrogative neutron self-shielding in these clusters was treated separately and resulted in a penalty coefficient larger than 20% to prevent an underestimation of the fissile mass within the drum. In this work, we have shown that the incorporation of a new parameter in the factorial design, representing the fissile mass fraction in these clusters, provides an alternative to the penalty coefficient. This new approach finally does not degrade the uncertainty of the original prediction, which was calculated without taking into consideration the possible presence of clusters. Consequently, the

Liquid wastes decontamination processes are mainly based on two techniques: Bulk processes and the so called Cartridges processes. The first technique has been developed for the French nuclear fuel reprocessing industry since the 60's in Marcoule and La Hague. It is a proven and mature technology which has been successfully and quickly implemented by AREVA at Fukushima site for the processing of contaminated waters. The second technique, involving cartridges processes, offers new opportunities for the use of innovative adsorbents. The AREVA process developed for Fukushima and some results obtained on site will be presented as well as laboratory scale resultsmore » obtained in CEA laboratories. Examples of new adsorbents development for liquid wastes decontamination are also given. A chemical process unit based on co-precipitation technique has been successfully and quickly implemented by AREVA at Fukushima site for the processing of contaminated waters. The asset of this technique is its ability to process large volumes in a continuous mode. Several chemical products can be used to address specific radioelements such as: Cs, Sr, Ru. Its drawback is the production of sludge (about 1% in volume of initial liquid volume). CEA developed strategies to model the co-precipitation phenomena in order to firstly minimize the quantity of added chemical reactants and secondly, minimize the size of co-precipitation units. We are on the way to design compact units that could be mobilized very quickly and efficiently in case of an accidental situation. Addressing the problem of sludge conditioning, cementation appears to be a very attractive solution. Fukushima accident has focused attention on optimizations that should be taken into account in future studies: - To better take account for non-typical aqueous matrixes like seawater; - To enlarge the spectrum of radioelements that can be efficiently processed and especially short lives radioelements that are usually less present

Objective To derive, cross validate, and externally validate a clinical prediction model that assesses the risks of different serious bacterial infections in children with fever at the emergency department. Design Prospective observational diagnostic study. Setting Three paediatric emergency care units: two in the Netherlands and one in the United Kingdom. Participants Children with fever, aged 1 month to 15 years, at three paediatric emergency care units: Rotterdam (n=1750) and the Hague (n=967), the Netherlands, and Coventry (n=487), United Kingdom. A prediction model was constructed using multivariable polytomous logistic regression analysis and included the predefined predictor variables age, duration of fever, tachycardia, temperature, tachypnoea, ill appearance, chest wall retractions, prolonged capillary refill time (>3 seconds), oxygen saturation <94%, and C reactive protein. Main outcome measures Pneumonia, other serious bacterial infections (SBIs, including septicaemia/meningitis, urinary tract infections, and others), and no SBIs. Results Oxygen saturation <94% and presence of tachypnoea were important predictors of pneumonia. A raised C reactive protein level predicted the presence of both pneumonia and other SBIs, whereas chest wall retractions and oxygen saturation <94% were useful to rule out the presence of other SBIs. Discriminative ability (C statistic) to predict pneumonia was 0.81 (95% confidence interval 0.73 to 0.88); for other SBIs this was even better: 0.86 (0.79 to 0.92). Risk thresholds of 10% or more were useful to identify children with serious bacterial infections; risk thresholds less than 2.5% were useful to rule out the presence of serious bacterial infections. External validation showed good discrimination for the prediction of pneumonia (0.81, 0.69 to 0.93); discriminative ability for the prediction of other SBIs was lower (0.69, 0.53 to 0.86). Conclusion A validated prediction model, including clinical signs, symptoms, and C

Most of the anthropogenic radionuclide 129 I released to the marine environment from the nuclear fuel reprocessing plants (NFRP) at Sellafield (England) and La Hague (France) is transported to the Arctic Ocean via the North Atlantic Current and the Norwegian Coastal Current. 129 I concentrations in seawater provides a powerful and well-established radiotracer technique to provide information about the mechanisms which govern water mass transport in the Nordic Seas and the Arctic Ocean and is gaining importance when coupled with other tracers (e.g. CFC, 236 U). In this work, 129 I concentrations in surface and depth profiles from the Nordic Seas and the North Atlantic (NA) Ocean collected from four different cruises between 2011 and 2012 are presented. This work allowed us to i) update information on 129 I concentrations in these areas, required for the accurate use of 129 I as a tracer of water masses; and ii) investigate the formation of deep water currents in the eastern part of the Nordic Seas, by the analysis of 129 I concentrations and temperature-salinity (T-S) diagrams from locations within the Greenland Sea Gyre. In the Nordic Seas, 129 I concentrations in seawater are of the order of 10 9 at·kg -1 , one or two orders of magnitude higher than those measured at the NA Ocean, not so importantly affected by the releases from the NFRP. 129 I concentrations of the order of 10 8 atoms·kg -1 at the Ellet Line and the PAP suggest a direct contribution from the NFRP in the NA Ocean. An increase in the concentrations in the Nordic Seas between 2002 and 2012 has been detected, which agrees with the temporal evolution of the 129 I liquid discharges from the NFRPs in years prior to this. Finally, 129 I profile concentrations, 129 I inventories and T-S diagrams suggest that deep water formation occurred in the easternmost area of the Nordic Seas during 2012.

The North Cotentin area (Normandy, France) hosts several nuclear facilities among which the AREVA reprocessing plant of La Hague is responsible for controlled discharges of liquid radioactive wastes into the marine environment. The resulting increase in radioactivity is very small compared to natural radioactivity. However, concerns about environment protection prompted the scientific community to focus on the effects of the chronic exposure to low concentrations of radionuclides in non-human biota. This study contributes to the evaluation of the possible impact of radioactive discharges on the oyster Crassostrea gigas in the field. Real-time polymerase chain reaction was used to quantify the expression levels of genes involved in cell stress in the oyster. They included members of the heat shock protein family (Hsp70, Hsc72, Hsp90), superoxide dismutase (SOD) and metallothionein (MT). Times series measurements were built from periodic samplings in the natural environment in order to characterize the natural variability as well as possible seasonal fluctuations. The genes studied exhibited a general seasonal expression pattern with a peak value in winter. The data inversely correlated with seawater temperature and the nature of the relationship between gene expression and temperature is discussed. In parallel, oysters were collected in four locations on the French shores, exposed or not to radioactive liquid wastes from the nuclear facilities hosted in the North Cotentin. The comparison of data obtained in the reference location on the Atlantic coast (not exposed) and data from oysters of the English Channel (exposed) gave no evidence for any statistical difference. However, because of the complexity of the natural environment, we cannot rule out the possibility that other parameters may have masked the impact of radioactive discharges. This dense set of data is a basis for the use of the expression levels of those genes as biomarkers to address the question of the

The fissile mass in radioactive waste drums filled with compacted metallic residues (spent fuel hulls and nozzles) produced at AREVA La Hague reprocessing plant is measured by neutron interrogation with the Differential Die-away measurement Technique (DDT. In the next years, old hulls and nozzles mixed with Ion-Exchange Resins will be measured. The ion-exchange resins increase neutron moderation in the matrix, compared to the waste measured in the current process. In this context, the Nuclear Measurement Laboratory (NML) of CEA Cadarache has studied a matrix effect correction method, based on a drum monitor ({sup 3}He proportional counter inside the measurement cavity).more » A previous study performed with the NML R and D measurement cell PROMETHEE 6 has shown the feasibility of method, and the capability of MCNP simulations to correctly reproduce experimental data and to assess the performances of the proposed correction. A next step of the study has focused on the performance assessment of the method on the industrial station using numerical simulation. A correlation between the prompt calibration coefficient of the {sup 239}Pu signal and the drum monitor signal was established using the MCNPX computer code and a fractional factorial experimental design composed of matrix parameters representative of the variation range of historical waste. Calculations have showed that the method allows the assay of the fissile mass with an uncertainty within a factor of 2, while the matrix effect without correction ranges on 2 decades. In this paper, we present and discuss the first experimental tests on the industrial ACC measurement system. A calculation vs. experiment benchmark has been achieved by performing dedicated calibration measurement with a representative drum and {sup 235}U samples. The preliminary comparison between calculation and experiment shows a satisfactory agreement for the drum monitor. The final objective of this work is to confirm the reliability of

What more can plant scientists do to help save the green stuff?

The Global Strategy for Plant Conservation (GSPC) was the first such effort under the Convention on Biological Diversity (CBD), and had gone through a 3-year process to reach the level of maturity that enabled it to be approved by consensus by all Governments present at the key session in The Hague in April 2002. It provided a model for subsequent CBD workplans, with targets, and undoubtedly contributed to the 2010 target of reducing the rate of biodiversity loss. In the event, few of the targets were achieved, because of numerous constraints at both policy and implementation levels. Even so, the GSPC stands as an important milestone in the global effort to conserve biodiversity. However, few plant scientists can be satisfied that the essential steps are being taken to ensure the conservation of plants, although, of course, plant scientists are only one part of the complex effort that will be required. This paper offers some suggestions that might be worth consideration, building on the basic principle in politics that a strong constituency is necessary to victory. In other words, although plant scientists play a crucial role, plant conservation is too important to leave in their hands alone; far broader support is required, including from the private sector, agriculture, forestry, trade, economics, tourism and even the military. Although botanical science provides a solid foundation, other branches of science are also important, ranging from anthropology to zoology. The legal profession also has important contributions to make (as well as the ability to hamper progress – for example through using issues such as access and benefit sharing to limit the exchange of genetic materials for even noncommercial use). 2010 was the United Nations Year of Biodiversity, and the GSPC targets reached their due date. It therefore seems timely to add some additional perspectives to the effort to update the GSPC. This paper suggests ways to reach a far broader constituency

The World Water Vision exercise was initiated by the World Water Commission under the auspices of the World Water Council. The goal of the World Water Vision project was to develop a widely shared vision on the actions required to achieve a common set of water-related goals and the necessary commitment to carry out these actions. The Vision should be participatory in nature, including input from both developed and developing regions, with a special focus on the needs of the poor, women, youth, children and the environment. Three overall objectives were to: (i)raise awareness of water issues among both the general population and decision-makers so as to foster the necessary political will and leadership to tackle the problems seriously and systematically; (ii) develop a vision of water management for 2025 that is shared by water sector specialists as well as international, national and regional decision-makers in government, the private sector and civil society; and (iii) provide input to a Framework for Action to be elaborated by the Global Water Partnership, with steps to go from vision to action, including recommendations to funding agencies for investment priorities. This exercise was characterized by the principles of: (i) a participatory approach with extensive consultation; (ii) Innovative thinking; (iii) central analysis to assure integration and co-ordination; and (iv) emphasis on communication with groups outside the water sector. The primary activities included, developing global water scenarios that fed into regional consultations and sectoral consultations as water for food, water for people - water supply and sanitation, and water and environment. These consultations formulated the regional and sectoral visions that were synthesized to form the World Water Vision. The findings from this exercise were reported and debated at the Second World Water Forum and the Ministerial Conference held in The Hague, The Netherlands during April 2000. This paper

Ethnic minorities (EM) from STI-endemic countries are at increased risk to acquire an STI. The objectives of this study were to investigate the difference in STI clinic consultation and positivity rates between ethnic groups, and compare findings between Dutch cities. Aggregated population numbers from 2011 to 2013 of 15-44 year-old citizens of Amsterdam, Rotterdam, The Hague and Utrecht extracted from the population register (N=3 129 941 person-years) were combined with aggregated STI clinic consultation data in these cities from the national STI surveillance database (N=113 536). Using negative binomial regression analyses (adjusted for age and gender), we compared STI consultation and positivity rates between ethnic groups and cities. Compared with ethnic Dutch (consultation rate: 40.3/1000 person-years), EM from Eastern Europe, Sub-Sahara Africa, Suriname, the Netherlands Antilles/Aruba and Latin America had higher consultation rates (range relative risk (RR): 1.27-2.26), whereas EM from Turkey, North Africa, Asia and Western countries had lower consultation rates (range RR: 0.29-0.82). Of the consultations among ethnic Dutch, 12.2% was STI positive. Positivity rates were higher among all EM groups (range RR: 1.14-1.81). Consultation rates were highest in Amsterdam and lowest in Utrecht independent of ethnic background (range RR Amsterdam vs Utrecht: 4.30-10.30). Positivity rates differed less between cities. There were substantial differences in STI clinic use between ethnic groups and cities in the Netherlands. Although higher positivity rates among EM suggest that these high-risk individuals reach STI clinics, it remains unknown whether their reach is optimal. Special attention should be given to EM with comparatively low consultation rates. Published by the BMJ Publishing Group Limited.

Instruments of Science and Citizenship: Science Education for Dutch Orphans During the Late Eighteenth Century

Roberts, Lissa L.

2012-01-01

One of the two most extensive instrument collections in the Netherlands during the second half of the eighteenth century—rivaling the much better known collection at the University of Leiden—belonged to an orphanage in The Hague that was specially established to mold hand-picked orphans into productive citizens. (The other was housed at the Mennonite Seminary in Amsterdam, for use in the education of its students.) The educational program at this orphanage, one of three established by the Fundatie van Renswoude, grew out of a marriage between the socially-oriented generosity of the wealthy Baroness van Renswoude and the pedagogical vision of the institute's director and head teacher—a vision that fit with the larger movement of oeconomic patriotism. Oeconomic patriotism, similar to `improvement' and oeconomic movements in other European countries and their colonies, sought to tie the investigation of nature to an improvement of society's material and moral well-being. Indeed, it was argued that these two facets of society should be viewed as inseparable from each other, distinguishing the movement from more modern conceptions of economics. While a number of the key figures in this Dutch movement also became prominent Patriots during the revolutionary period at the end of the century, fighting against the House of Orange, they did not have a monopoly on oeconomic ideas of societal improvement. This is demonstrated by the fact that an explicitly pro-Orangist society, Mathesis Scientiarum Genitrix, was organized in 1785 to teach science and mathematics to poor boys and orphans for very similar reasons: to turn them into productive and useful citizens. As was the case with the Fundatie van Renswoude, a collection of instruments was assembled to help make this possible. This story is of interest because it discusses a hitherto under-examined use to which science education was put during this period, by revealing the link between such programs and the highly

An important role for education is to inform and create the right skills for people to develop their own vision, using their talents to the utmost and inspire others to learn to explore in the future. Great effort has been taken to prepare this interactive design workshop thoroughly. Three days in a row, starting with presentations of Artscience The Hague to ESA colleagues, followed by a Planetary research Symposium in Amsterdam and a student design workshop at the end complemented a rich environment with the focus on Planetary exploration. The design workshop was organised by GeoVUsie students, with ESTEC and ILEWG support for tutors and inviting regional and international students to participate in an interactive workshop to design 5 Planetary Missions, with experts sharing their expertise and knowhow on specific challenging items: 1. Mercury - Post BepiColombo (with Sebastien Besse, ESA) 2. Moon South Pole Mission (with Bernard Foing, ESA) 3. Post-ExoMars - In search for Life on Mars (with Jorge Vago, ESA) 4. Humans in Space - Mars One investigated(with Arno Wielders, Space Horizon) 5. Europa - life on the icy moon of Jupiter? (with Bert Vermeersen, TU Delft. Lectures were given for more than 150 geology students at the symposium "Moon, Mars and More" at VU university, Amsterdam (organized by GeoVUsie earth science students). All students were provided with information before and at start for designing their mission. After the morning session there was a visit to the exhibition at The Erasmus Facility - ESTEC to inspire them even more with real artifacts of earlier and future missions into space. After this visit they prepared their final presentations, with original results, with innovative ideas and a good start to work out further in the future. A telescope session for geology students had been organized indoor due to rain. A follow-up visit to the nearby public Copernicus observatory was planned for another clear sky occasion.

This document details the progress to date on the ''OPTIMIZATION OF MUD HAMMER DRILLING PERFORMANCE--A PROGRAM TO BENCHMARK THE VIABILITY OF ADVANCED MUD HAMMER DRILLING'' contract for the quarter starting April 2004 through June 2004. The DOE and TerraTek continue to wait for Novatek on the optimization portion of the testing program (they are completely rebuilding their fluid hammer). The latest indication is that the Novatek tool would be ready for retesting only 4Q 2004 or later. Smith International's hammer was tested in April of 2004 (2Q 2004 report). Accomplishments included the following: (1) TerraTek re-tested the ''optimized'' fluid hammermore » provided by Smith International during April 2004. Many improvements in mud hammer rates of penetration were noted over Phase 1 benchmark testing from November 2002. (2) Shell Exploration and Production in The Hague was briefed on various drilling performance projects including Task 8 ''Cutter Impact Testing''. Shell interest and willingness to assist in the test matrix as an Industry Advisor is appreciated. (3) TerraTek participated in a DOE/NETL Review meeting at Morgantown on April 15, 2004. The discussions were very helpful and a program related to the Mud Hammer optimization project was noted--Terralog modeling work on percussion tools. (4) Terralog's Dr. Gang Han witnessed some of the full-scale optimization testing of the Smith International hammer in order to familiarize him with downhole tools. TerraTek recommends that modeling first start with single cutters/inserts and progress in complexity. (5) The final equipment problem on the impact testing task was resolved through the acquisition of a high data rate laser based displacement instrument. (6) TerraTek provided Novatek much engineering support for the future re-testing of their optimized tool. Work was conducted on slip ring [electrical] specifications and tool collar sealing in the testing vessel with a reconfigured flow system on Novatek's collar.« less

Sexually transmitted infection (STI) screening programmes are implemented in many countries to decrease burden of STI and to improve sexual health. Screening for Chlamydia trachomatis and Neisseria gonorrhoeae has a prominent role in these protocols. Most of the screening programmes concerning men having sex with men (MSM) are based on opportunistic urethral testing. In The Netherlands, a history-based approach is used. The aim of this study is to evaluate the protocol of screening anatomic sites for C. trachomatis and N. gonorrhoeae infection based on sexual history in MSM in routine practice in The Netherlands. All MSM visiting the clinic for STI in The Hague are routinely asked about their sexual practice during consulting. As per protocol, tests for urogenital, oropharyngeal and anorectal infection are obtained based on reported site(s) of sexual contact. All consultations are entered into a database as part of the national STI monitoring system. Data of an 18 months period were retrieved from this database and analysed. A total of 1455 consultations in MSM were registered during the study period. The prevalence of C. trachomatis and N. gonorrhoeae per anatomic site was: urethral infection 4.0% respectively and 2.8%, oropharynx 1.5% and 4.2%, and anorectum 8.2% and 6.0%. The majority of chlamydia cases (72%) involved a single anatomic site, which was especially manifest for anorectal infections (79%), while 42% of gonorrhoea cases were single site. Twenty-six percent of MSM with anorectal chlamydia and 17% with anorectal gonorrhoea reported symptoms of proctitis; none of the oropharyngeal infections were symptomatic. Most cases of anorectal infection (83%) and oropharyngeal infection (100%) would have remained undiagnosed with a symptom-based protocol. The current strategy of sexual-history based screening of multiple anatomic sites for chlamydia and gonorrhoea in MSM is a useful and valid guideline which is to be preferred over a symptom-based screening

Domestic Violence and Abuse (DVA) is associated with a range of psychosocial and mental health problems. Having a psychiatric illness increases likelihood of being a victim of DVA. Despite the evidence of a high risk for DVA and the serious effects of violent victimization in psychiatric patients, detection rates are low and responses are inadequate. The aim of the BRAVE (Better Reduction trough Assessment of Violence and Evaluation) study is to improve detection of and response to DVA in psychiatric patients. In this article, we present the protocol of the BRAVE study which follows the SPIRIT guidelines. The BRAVE study is a cluster randomized controlled trial. We will include 24 community mental health teams from Rotterdam and The Hague. Twelve teams will provide care as usual and 12 teams will receive the intervention. The intervention consists of 1) a knowledge and skills training for mental health professionals about DVA, 2) a knowledge and skills training of DVA professionals about mental illness, 3) provision and implementation of a referral pathway between community mental health and DVA services. The follow up period is 12 months. Our primary outcome is the rate of detected cases of recent or any history of DVA in patients per team in 12 months. Detection rates are obtained through a systematic search in electronic patient files. Our secondary aims are to obtain information about the gain and sustainability of knowledge on DVA in mental health professionals, and to obtain insight into the feasibility, sustainability and acceptability of the intervention. Data on our secondary aims will be obtained through structured in depth interviews and a questionnaire on knowledge and attitudes on DVA. This study is the first cluster randomized controlled trial to target both male and female psychiatric patients that experience DVA, using an intervention that involves training of professionals. We expect the rate of detected cases of DVA to increase in the

1 Reevaluation of the integrated horizontal flux approach

Neftel, Albrecht; Häni, Christoph; Hensen, Arjan

2017-04-01

The integrated horizontal flux (IHF) method is a simplified mass balance approach frequently used to determine emissions from confined source areas, e.g. NH3 emissions from slurry spread to a circular plot (Denmead, 2008). With a mast in the center of the circle with radius R, the total flux F of the upwind emitted NH3 is approximated from the measured vertical (z) profiles of concentration (c) and horizontal wind speed (u) as (Denmead 1983): F = 1/R\\intz=zplz=0\\overline{u(c - cbgd)}dz where cbgd is the ``background'' concentration upwind of the emitting area and zpl is the maximum height of the emission plume (where the concentration c equals cbgd).The IHF method is a robust approach, as it is independent of surface characteristics and the state of atmospheric diffusion (Denmead, 2008; Laubach,2010). Ryden and McNeill (1984) published guidelines on how to evaluate IHF measurements, which have been used in many investigations that followed. In the following we analyze systematic biases that might occur by applying different recipes to both modelled concentration profiles as well as measured profiles from a recent field experiment in the Netherlands. Typical differencs using the approach by Ryden et al. (1984) are in the order +10% to +30% compared to the reference values from the model or alternative determination of the emissions based on the experimental values. The positive biases consist of several contributions: horizontal diffusion, logarithmic fit of the concentration profile, displacement height. References Denmead, O. T., 1983.

Investigations of Periodic Disturbances on Seismic Aftershock Recordings

The Comprehensive Nuclear Test-Ban Treaty Organisation (CTBTO) runs the International Monitoring System (IMS) to detect possible violations of the treaty. The seismic sensors of the IMS are set up to detect every underground explosion with a yield of 1 kT TNT equivalent or even better everywhere on the world. Under consideration of all IMS data the hypocentre of a large underground explosion is located within an area of about 1000 sq km. To verify if it was a violation of the Test-Ban Treaty the CTBTO (after CTBT entry into force) is allowed to carry out an on-site inspection (OSI) in the area of suspicion. During an OSI the hypocentre is to be located much more precisely; for this a local seismic aftershock monitoring system (SAMS) can be installed to detect small seismic events caused as a consequence of the explosion, such as relaxation of the rock around the cavity. However the magnitude of these aftershock signals is extremely weak. Other difficulties arise from other seismic signals in the inspection area, for example caused by vehicles of the inspectors, from coupling of airborne signals to the ground, or even by intended attempts to disturb the OSI. While the aftershock signals have a pulsed shape, man-made seismic signals (primarily created by engines) usually show periodic characteristics and thus are representable as a sum of sine functions and their harmonics. A mathematical expression for the Hann-windowed discrete Fourier transform of the underlying sine is used to characterise every such disturbance by the amplitude, frequency and phase. The contributions of these sines are computed and subtracted from the complex spectrum sequentially. Synthetic sines superposed to real signals, orders of magnitude stronger than the latter, can be removed successfully. Removal of periodic content from the signals of a helicopter overflight reduces the amplitude by a factor 3.3 when the frequencies are approximately constant. To reduce or prevent disturbing seismic

searching for a new physician, respondents significantly more often reported that family, friends and colleagues (259/277, 93.5%), other physicians (219/274, 79.9%), and practice websites (108/266, 40.6%) were important information sources. Whereas awareness of German PRWs appears to have substantially increased, the use of PRWs and contribution of ratings remains relatively low. Further research is needed to examine the reasons why only a few patients are rating physicians. However, given the information inequality between provider and consumer will always be higher for consumers using the services of physicians, it is possible that people will always rely more on interpersonal recommendations than impersonal public information before selecting a physician. ©Stuart McLennan, Daniel Strech, Andrea Meyer, Hannes Kahrass.

We previously demonstrated that compliance with occlusion therapy for amblyopia was improved by the use of an educational programme, especially in children of parents of foreign origin and who spoke Dutch poorly. The programme consisted of: (i) a cartoon story for amblyopic children that explained without words why they should patch, (ii) a calendar with reward stickers, and (iii) an information leaflet for parents. In the current study, we assessed the individual effect of each component on compliance. We recruited 120 3- to 6-year-old children who lived in a low socio-economic status (SES) area in The Hague and were starting occlusion therapy for the first time. They were randomised to receive one of the components (three intervention groups), or a picture to colour (control group). The randomisation was blinded for treating orthoptist and researcher. Compliance was measured electronically using the Occlusion Dose Monitor (ODM). Primary outcome was percentage of compliance (actual/prescribed occlusion time). Secondary outcome was absolute occlusion hours per day. Parental fluency in Dutch was rated on a five-point scale. Compliance could be measured electronically in 88 of the 120 children; in 32 others, it failed for various reasons. Parental fluency in Dutch was moderate or worse in 36.4 % (p = 0.327). Average compliance was 55 % standard deviation (SD) 40 (n = 18) in the control group, 89 % SD 25 in the group receiving the educational cartoon (n = 25, P = 0.002 compared with control group), 67 % SD 33 (n = 24, P = 0.301) in the reward-calendar group and 73 % SD 40 (n = 21, P = 0.119) in the parent-information-leaflet group. On average, children in the control group occluded 1:46 SD1:19 hours/day, 2:33 SD 1:18 hours/day in the group receiving the educational cartoon, 1:59 SD 1:13 hours/day in the reward-calendar group and 2:18 SD 1:13 hours/day in the parent-information-leaflet group. No child who received the cartoon story occluded less than 1 hour per day

The most striking conclusion is the unsuitability of rational policy analytic approaches for The Netherlands. Although surprising this conclusion finds some support in the process dominated approach taken in the Dutch Delta Program.

The use of 'easy-to-read' materials for people with intellectual disabilities has become very widespread but their effectiveness has scarcely been evaluated. In this study, the framework provided by Kintsch's Construction-Integration Model (1988) is used to examine (i) the reading comprehension levels of different passages of the Spanish text that have been designed following easy-to-read guidelines and (ii) the relationships between reading comprehension (literal and inferential) and various linguistic features of these texts. Sixteen students with mild intellectual disability and low levels of reading skills were asked to read easy-to-read texts and then complete a reading comprehension test. The corpus of texts was composed of a set of forty-eight pieces of news selected from www.noticiasfacil.es, a Spanish digital newspaper that publishes daily journalistic texts following international guidelines for the design of easy-to-read documents (IFLA, Tronbacke B. (1997) Guidelines for Easy-to-read Materials. IFLA, The Hague). Participants correctly answered 80% of the comprehension questions, showing significantly higher scores for literal questions than for inferential questions. The analyses of the texts' linguistic features revealed that the number of coreferences was the variable that best predicted literal comprehension, but contrary to what the previous literature seemed to indicate, the relationship between the two variables was inverse. In the case of inferential comprehension, the number of sentences was a significant negative predictor; that is, the higher the sentence density, the lower the ability of these students to find relationships between them. The effects of the rest of linguistic variables, such as word frequency and word length, on comprehension were null. These results provide preliminary empirical support for the use of easy-to-read texts but bring into question the validity of some popular design guidelines (e.g. augmenting word frequency) to

High resolution modelling of extreme precipitation events in urban areas

2015-04-01

The present day society needs to adjust to the effects of climate change. More extreme weather conditions are expected, which can lead to longer periods of drought, but also to more extreme precipitation events. Urban water systems are not designed for such extreme events. Most sewer systems are not able to drain the excessive storm water, causing urban flooding. This leads to high economic damage. In order to take appropriate measures against extreme urban storms, detailed knowledge about the behaviour of the urban water system above and below the streets is required. To investigate the behaviour of urban water systems during extreme precipitation events new assessment tools are necessary. These tools should provide a detailed and integral description of the flow in the full domain of overland runoff, sewer flow, surface water flow and groundwater flow. We developed a new assessment tool, called 3Di, which provides detailed insight in the urban water system. This tool is based on a new numerical methodology that can accurately deal with the interaction between overland runoff, sewer flow and surface water flow. A one-dimensional model for the sewer system and open channel flow is fully coupled to a two-dimensional depth-averaged model that simulates the overland flow. The tool uses a subgrid-based approach in order to take high resolution information of the sewer system and of the terrain into account [1, 2]. The combination of using the high resolution information and the subgrid based approach results in an accurate and efficient modelling tool. It is now possible to simulate entire urban water systems using extreme high resolution (0.5m x 0.5m) terrain data in combination with a detailed sewer and surface water network representation. The new tool has been tested in several Dutch cities, such as Rotterdam, Amsterdam and The Hague. We will present the results of an extreme precipitation event in the city of Schiedam (The Netherlands). This city deals with

AIM: To evaluate the efficacy of lower esophageal sphincter (LES)-electrical stimulation therapy (EST) in a subgroup of patients that reported only partial response to proton pump inhibitors (PPIs) therapy, compared to a group of patient with complete response. METHODS: Bipolar stitch electrodes were laparoscopically placed in the LES and connected to an implantable pulse generator (EndoStim BV, the Hague, the Netherlands), placed subcutaneously in the anterior abdominal wall. Stimulation at 20 Hz, 215 μsec, 3-8 mAmp in 30 min sessions was delivered starting on day 1 post-implant. Patients were evaluated using gastroesophageal reflux disease (GERD)-HRQL, symptom diaries; esophageal pH and esophageal manometry before and up to 24 mo after therapy and results were compared between partial and complete responders. RESULTS: Twenty-three patients with GERD on LES-EST were enrolled and received continuous per-protocol stimulation through 12 mo and 21 patients completed 24 mo of therapy. Of the 23 patients, 16 (8 male, mean age 52.1 ± 12 years) had incomplete response to PPIs prior to LES-EST, while 7 patients (5 male, mean age 52.7 ± 4.7) had complete response to PPIs. In the sub-group with incomplete response to PPIs, median (IQR) composite GERD-HRQL score improved significantly from 9.5 (9.0-10.0) at baseline on-PPI and 24.0 (20.8-26.3) at baseline off-PPI to 2.5 (0.0-4.0) at 12-mo and 0.0 (0.0-2.5) at 24-mo follow-up (P < 0.05 compared to on-and off-PPI at baseline). Median (IQR) % 24-h esophageal pH < 4.0 at baseline in this sub-group improved significantly from 9.8% (7.8-11.5) at baseline to 3.0% (1.9-6.3) at 12 mo (P < 0.001) and 4.6% (2.0-5.8) at 24 mo follow-up (P < 0.01). At their 24-mo follow-up, 9/11 patients in this sub-group were completely free of PPI use. These results were comparable to the sub-group that reported complete response to PPI therapy at baseline. No unanticipated implantation or stimulation-related adverse events, or any untoward sensation

Reconstruction of Holocene palaeoclimate and environment in the Khatanga region, Russian Arctic

Arctic regions are highly sensitive to changes in temperature and precipitation, and their Late Quaternary environmental history is very important for understanding of present and past climate trends. Though the timing of Holocene climate change is well established for wide parts of the Northern Hemisphere, suitable palaeoenvironmental records are still scarce in the Russian Siberian Arctic. Taimyr Peninsula (74oN, 100oE) is the northernmost part of Russia. Thus, this area is probably one of the most promising regions for the reconstruction of the Late Quaternary environment in dependence on changes in global and regional climate and the atmospheric circulation. (Andreev et al., 2004).The area is characterized by a continental climate with long, severe winters, and short summers. The modern temperatures are about 10-14oC in July, and - 32 to 34oC in January. Annual precipitation ranges from about 300-400 mm at low elevations to about 600-800 mm on the western slopes of the Putorana Plateau (Atlas Arktiki, 1985). The frost-free period is ca. 35 days. Almost all the territory is underlain by continues permafrost. Periglacial landscape is dominated by tundra and taiga vegetation. Aquatic organisms such as chironomids (Insecta: Diptera) are recognized as the best biological indicators for quantifying past changes in air temperature or lake chemistry (Letter et al., 1997; Brooks and Birks, 2000; Battarbee, 2000; Massaferro and Brooks, 2002; Solovieva et al., 2005). Chironomids belong to the most abundant group of fresh-water bottom-dwelling macroinvertebrates. Because of their short life cycle, chironomids quickly adapt to environmental changes and in global scale the distribution and abundance of chironomids are mostly limited by temperature (Walker and Mathewes, 1987; Warwick, 1989; Hann et al., 1992; Walker et al., 1992). Larval head capsules of chironomids preserved in lake sediment as subfossils are abundant, identifiable and serve as indicators of the

In patients with sciatica due to a lumbar disc herniation, it is generally recommended to reserve surgical treatment for those who suffer from intolerable pain or those who demonstrate persistent symptoms after conservative management. Controversy exists about the necessity of early surgical intervention for those patients that have an additional motor deficit. The aim of this study was to compare the recovery of motor deficit among patients receiving early surgery to those receiving prolonged conservative treatment. Subgroup analysis of a randomized controlled trial. This subgroup analysis focuses on 150 (53%) of 283 patients with sciatica due to a lumbar disc herniation and whose symptoms at baseline (before randomization) were accompanied by a motor deficit. Motor deficit was assessed through manual muscle testing and graded according to the Medical Research Council (MRC) scale. In total, 150 patients with 6 to 12 weeks of sciatica due to a lumbar disc herniation and whose symptoms were accompanied by a moderate (MRC Grade 4) or severe (MRC Grade 3) motor deficit were randomly allocated to early surgery or prolonged conservative treatment. Repeated standardized neurologic examinations were performed at baseline and at 8, 26, and 52 weeks after randomization. This study was supported by a grant from the Netherlands Organization for Health Research and Development (ZonMW) and the Hoelen Foundation The Hague. Sciatica recovered among seven (10%) of the 70 patients assigned to early surgery before surgery could be performed, and of the 80 patients assigned to conservative treatment, 32 patients (40%) were treated surgically because of intolerable pain. Baseline severity of motor deficit was graded moderate in 84% of patients and severe in 16% of patients. Motor deficit recovered significantly faster among patients allocated to early surgery (p=.01), but the difference was no longer significant at 26 (p=.21) or 52 weeks (p=.92). At 1 year, complete recovery of motor

The Plasma Physics Hannes Alfvén Prize 2010 The Hannes Alfvén Prize is awarded to Allen Boozer (Professor, Columbia University) and Jürgen Nührenberg (Professor, Max-Planck-Institut für Plasmaphysik and Greifswald University) for the formulation and practical application of criteria allowing stellarators to have good fast-particle and neoclassical energy confinement. Photo of Boozer and Nuhrenberg Jürgen Nührenberg (left) and Allen Boozer. The tokamak and the stellarator are two major candidate concepts for magnetically confining fusion plasmas. They were both conceived in the early 1950s, but the tokamak developed more rapidly because of its intrinsically favourable confinement properties. Indeed, the stellarator seemed fundamentally unable to confine energy and collisionless alpha-particle orbits well enough for a fusion reactor. In the 1980s, however, Allen Boozer and Jürgen Nührenberg developed methods for tailoring stellarator magnetic fields so as to guarantee confinement comparable to that in tokamaks. Allen Boozer introduced a set of magnetic coordinates, now named after him, in which the description of three-dimensionally shaped magnetic fields is particularly simple. He went on to show that if the magnetic field strength |B| is symmetric in these coordinates (so-called quasisymmetry) then the guiding-centre orbits and the neoclassical confinement properties are equivalent to those in a tokamak. In pioneering calculations a few years later, Jürgen Nührenberg showed that such magnetic fields can indeed be realized in practice, as can other configurations which have equally good confinement without being quasisymmetric. There is an unexpected vastness of configurational possibilities for toroidal plasma confinement, where the limit is likely to be set by turbulence rather than neoclassical losses. In addition, quasisymmetry should facilitate the development of strongly sheared

Since in 1984 the national reprocessing concept was abandoned the reprocessing abroad was the only existing disposal route until 1994. With the amendment of the Atomic Energy Act in 2001 spent fuel management changed completely since from 1 June 2005 any delivery of spent fuel to reprocessing plants was prohibited and the direct disposal of spent fuel became mandatory. Until 2005 the total amount of spent fuel to be reprocessed abroad added up to 6080 t HM, 5309 t HM thereof in France. The waste generated from reprocessing - alternatively an equivalent amount of radioactive material - has to bemore » returned to the country of origin according to the commercial contracts signed between the German utilities and COGEMA, now AREVA NC, in France and BNFL, now INS in UK. In addition the German and the French government exchanged notes with the obligation of both sides to enable and support the return of reprocessing residues or equivalents to Germany. The return of high active vitrified waste from La Hague to the interim storage facility at Gorleben was demanding from the technical view i. e. the cask design and the transport. Unfortunately the Gorleben area served as a target for nuclear opponents from the first transport in 1996 to the latest one in 2011. The protection against sabotage of the railway lines and mass protests needed highly improved security measures. In France and Germany special working forces and projects have been set up to cope with this extraordinary situation. A complex transport organization was established to involve all parties in line with the German and French requirements during transport. The last transport of vitrified residues from France has been completed successfully so far thus confirming the efficiency of the applied measures. Over 15 years there was and still is worldwide no comparable situation it is still unique. Summing up, the exceptional project handling challenge that resulted from the continuous anti-nuclear civil

This special issue includes selected papers on the topic of earthquake impact from the sessions held in 2004 in Nice, France and in 2005 in Vienna, Austria at the first and respectivelly the second European Geosciences Union General Assembly. Since its start in 1999, in the Hague, Netherlands, the hazard of earthquakes has been the most popular of the session. The respective calls in 2004 was for: Nature's forces including earthquakes, floods, landslides, high winds and volcanic eruptions can inflict losses to urban settlements and man-made structures such as infrastructure. In Europe, recent years have seen such significant losses from earthquakes in south and south-eastern Europe, floods in central Europe, and wind storms in western Europe. Meanwhile, significant progress has been made in understanding disasters. Several scientific fields contribute to a holistic approach in the evaluation of capacities, vulnerabilities and hazards, the main factors on mitigating urban disasters due to natural hazards. An important part of the session is devoted to assessment of earthquake shaking and loss scenarios, including both physical damage and human causalities. Early warning and rapid damage evaluation are of utmost importance for addressing the safety of many essential facilities, for emergency management of events and for disaster response. In case of earthquake occurrence strong motion networks, data processing and interpretation lead to preliminary estimation (scenarios) of geographical distribution of damages. Factual information on inflicted damage, like those obtained from shaking maps or aerial imagery permit a confrontation with simulation maps of damage in order to define a more accurate picture of the overall losses. Most recent developments towards quantitative and qualitative simulation of natural hazard impacts on urban areas, which provide decision-making support for urban disaster management, and success stories of and lessons learned from disaster

quantities of foam were produced, affecting the evaporator operation, and creating the risk of a reduction in its capacity and throughput performance. A task force of AREVA process, operations, and safety experts from Marcoule and the La Hague reprocessing complex was assembled. New operating parameters were defined and tested to improve the process. Since then, the evaporator has performed very satisfactorily. The foam buildup phenomenon has been brought under complete control. All the different types of effluents produced during cleanup operations have been concentrated, and the results obtained in terms of quality and throughput, have ensured a consistent supply to the vitrification unit. The evaporator was operated until the end of April 2012, and enabled the production of 500 cubic meters of very high activity effluent, concentrating the fission products rinsed from the storage tanks. The evaporator will now be deactivated and decommissioned, with the first rinsing and cleanup operations scheduled to begin in 2014. (authors)« less

large quantities of sediment towards sea through its inlet. This export was estimated to be roughly 2 to 3 million m3 per year, and was observable as deepening channels inside the basin, and a growing ebb-tidal delta. The implementation of the dams caused a significant increase in tidal prism, while at the same time they stopped the residual flow of water from the Eastern Scheldt towards the northern basins. The increase in tidal prism was observable in the response of bathymetry; the rates of channel deepening and ebb-tidal delta growth both increased. Analysis of tidal flow measurements and model output show a persistent trend for sediment transport towards and out of the Eastern Scheldt's inlet. This export is caused by both the strong ebb-directed asymmetry in the tidal flow as well as higher sediment concentrations during ebb. The construction of the back-barrier dams only amplified this export by cutting off the residual import of flow and by causing the basin to be out of equilibrium even more than it apparently already was.

Development: In order to delve deeper into the subject of freedom in space and science this setup can serve as a vantage point. And it can offer an interactive environment to explore notions of freedom in space and science. The addition of a specific environment around and above the installation, referring to the fabric of space would highly increase the impact it has on an audience. You would then be able to immerse yourself in the world of this settlement, somewhere in outer space. Sound, light and projection screens will orbit the table changing the projections even more.

, with the likely addition of inputs from reprocessing facilities and reactor operations. As with Pu/Cs ratios, Np/Pu ratios could be modified by differential geochemical behaviors of Np and Pu. Dissolved 129I only weakly interacts with particles in the Ob; size-fractionated sampling shows that the colloidal 129I fraction (defined as 1 kDa-0.2 μm) contains generally <5% relative to that passing a 0.2 μm filter. Iodine-129 concentrations decrease from 8.3×10 9 to 0.65×10 9 atoms l -1 through the Ob system toward the Kara Sea, with highest values in the Tobal River and lowest in the Taz River. The likely source of the elevated 129I in the Tobal is release from the production-reprocessing facilities at Mayak, and decreases downriver are predominantly due to dilution as the various tributaries with low 129I join the system. Fluxes of 129I to the lower Ob at Salekhard are <1% of the releases of this radionuclide from the nuclear fuel reprocessing facilities at Sellafield, UK and La Hague, France.

This is done in an ordered fashion following statistical design rules, which allows to extract main effects of each of the factors considered (coupling, better circulation information, data assimilation following Lionello et al., 1992) as well as two-factor interactions. Moreover, the statistical significance of these improvements can be tested in the future, though this requires maximum likelihood ratio tests with correlated data. Charnock, H.

The author of the present article proves the veracity of the postulate, which was formulated by Bogdan Suchodolski and concerned the necessity of popularizing the history of science. The stipulation is still greatly important for many fields of human activity. Bogdan Suchodolski was not the first and the only thinker, who revealed the unquestionable significance of disseminating the history of science as scientific branch: For the first time the problem was noticed in 1900 during International Congress of Comparative History in Paris and in 1903 during International Congress of Historical Sciences in Rome, when the idea of universalizing the history of science was put forward, among others, by: Paul Tannery, Carre de Vaux, Gino Ioria and Karl Sudhoff. All the mentioned participants declared then the necessity of teaching the history of science both in the secondary schools and in the universities. In the article was also included a detailed description of conceptions formulated by Paul Tannery and Michel Lhéritier in the inter-war period that concerned popularizing the history of science, and differed much from each other. Unlike Paul Tannery, Michel Lhéritier advised against separating history of science from the whole of history. On the occasion of describing the inter-war period the author is paying a special attention to the role, which was played by International Conference of Teaching History in Hague in 1932. In that time a representative of International Committee on the History of Sciences and International Academy of the History of Sciences--Aldo Mieli--presented the idea of disseminating the history of science, which resulted in a resolution saying that the discussed branch should be taught in the primary and secondary schools, and in the universities as well. Further, the paper includes the description of the detailed conceptions that were put forward after World War II by the members of Committee on Teaching within International Academy of the

, and 2 longer ones, which include several short-term periods. Short-term periods spread from 1 to 3 months, whereas long-term periods indicate 2 and 5 years. The simulation results showed an acceptable agreement with the measurements. It was also found that the long-term periods had less deviation to the measurements than the short ones. This simplified method exhibited clear savings in computational time compared to the instationary simulations; in this case only 3 hours of computational time were needed for 5 years simulation period using the reference computer mentioned above. Further research is needed with respect to the limits of this linear approach, i.e. with respect to the frequency with which the set of steady simulations has to be updated due to significant changes in morphology and in turn in hydraulics. Yet, the preliminary results are promising, suggesting that the developed approach is very suitable for a long-term simulation of riverbed evolution. REFERENCES Olsen, N.R.B. 2014.

An important role for education is to inform and create the right skills for people to develop their own vision, using their talents to the utmost and inspire others to learn to explore in the future. Great effort has been taken to prepare this interactive design workshop thoroughly. Three days in a row, starting with presentations of Artscience The Hague to ESA colleagues, followed by a Planetary research Symposium in Amsterdam and a student design workshop at the end complemented a rich environment with the focus on Planetary exploration. The design workshop was organised by GeoVUsie students, with ESTEC and ILEWG support for tutors and inviting regional and international students to participate in an interactive workshop to design 5 Planetary Missions, with experts sharing their expertise and knowhow on specific challenging items: 1. Mercury - Post BepiColombo (with Sébastien Besse, ESA) 2. Moon South Pole Mission (with Bernard Foing, ESA) 3. Post-ExoMars - In search for Life on Mars (with Jorge Vago, ESA) 4. Humans in Space - Mars One investigated(with Arno Wielders, Space Horizon) 5. Europa - life on the icy moon of Jupiter? (with Bert Vermeersen, TU Delft) Lectures were given for more than 150 geology students at the symposium “Moon, Mars and More” at VU university, Amsterdam (organized by GeoVUsie earth science students). All students were provided with information before and at start for designing their mission. After the morning session there was a visit to the exhibition at The Erasmus Facility - ESTEC to inspire them even more with real artifacts of earlier and future missions into space. After this visit they prepared their final presentations, with original results, with innovative ideas and a good start to work out further in the future. A telescope session for geology students had been organized indoor due to rain. A follow-up visit to the nearby public Copernicus observatory was planned for another clear sky occasion.

The papers in this issue are dedicated to Professor Horst Paul Strunk on the occasion of his 65th birthday and his retirement from active teaching. This volume honours a scientist who has made a lasting impact on the field in electron microscopic characterisation of growth and relaxation phenomena in epitaxial growth of semiconductors. Born in The Hague, The Netherlands, on 13 June 1940, he studied physics in Stuttgart where he received his degree in Physics in 1968. He joined the group of Prof. Seeger at the Max-Planck-Institut für Metallforschung and defended his Ph.D. on defects in NaCl at Stuttgart University in 1973. He spent one year at Cornell University as a visiting Professor before joining Technische Universität Hamburg-Harburg in 1983. There he created the Zentralbereich Elektronenmikroskopie and was a professor for materials analytics from 1983 till 1989. In 1989 he changed to the University of Erlangen-Nürnberg, where he established the Verbundlabor für hochauflösende Elektronenmikroskopie and directed the Lehrstuhl Mikrocharakterisierung at the Institut für Werkstoffwissenschaften of the same university. He spent two research periods at the Universities of Rennes in France and Campinas in Brazil. Together with his colleague Prof. Jürgen Werner he created the series of conferences on polycrystalline semiconductors POLYSE which he has been supervising together with Jürgen Werner since 1990.The research activities of Horst P. Strunk are focused on microstructure of materials and their relation to macroscopic physical properties. Main topics are dislocations, their formation and interaction mechanisms, strain relaxation as well as fundamental mechanisms of epitaxial growth. The spectrum of materials covers a wide range starting from metals over ionic crystals, e.g. NaCl to elemental and compound semiconductors. From the beginning, the main tool of study has been the transmission electron microscope. However, Horst P. Strunk recognised that a

Much of what Hannes Alfvén envisaged some 70 years ago has now penetrated virtually all branches of astrophysical research. Indeed, magnetic fields can display similar properties over a large range of scales. We have therefore been able to take advantage of the transparency of galaxies and the interstellar medium to obtain measurements inside them. On the other hand, the Sun is much closer, allowing us to obtain a detailed picture of the interaction of flows and magnetic fields at the surface, and more recently in the interior by helioseismology. Moreover, the solar timescales are generally much shorter, making studies of dynamical processes more direct. This special issue on current research in astrophysical magnetism is based on work discussed during a one month Nordita program Dynamo, Dynamical Systems and Topology and comprises papers that fall into four different categories (A)-(D).

This in turn is complemented by realistic simulations of subsurface and surface flow patterns (paper 3). (B) Papers on theoretical approaches to turbulent fluctuations 4. Nathan Kleeorin and Igor

. The hydrology of East and West Maui is conspicuously different in many respects, mainly because of the difference in the stage of dissection, the extensive veneer of very permeable Hann lavas on East Maui, and the comparatively small area of the Lahaina lavas of similar age on West Maui. The only thermal water known in the Hawaiian Islands, except on the active volcano of Kilauea, is in a well in West Maui.The Nahiku area has been mapped and studied in detail. The upper part of the Honomanu volcanic series, exposed in the sea cliffs, in petrographic character is transitional into the overlying Kula lavas, Kula and Hana time were characterized by a long succession of valley-cutting episodes, each valley being filled by lava erupted from the east rift zone. The lavas include olivine basalts, picritic basalts, and basaltic andesites,In the Nahiku area basal ground water occurs largely in the Honomanu basalts. Perched water occurs in many of the later lavas, generally following the axes of buried valleys. The members which perch the water are mostly ashy soil beds, although an unusually extensive, thick layer of much decomposed clinker also appears to be a supporting member. Most of the water travels through the basal clinker members of aa lavas. Artesian water is encountered in the upper, transitional part of the Honomanu volcanic series. The aquifer is permeable porphyritic pahoehoe; the confining members are relatively impermeable nonporphyritic aa.The lavas of East Maui are described according to stratigraphic groups. The oldest or Honomanu lavas are olivine basalts like the primitive lavas in other Hawaiian volcanoes. The later or Kula and Hana lavas include basalts, basaltic andesites, andesites, and picritic basalts. The normative nepheline of analyzed East Maui lavas has not been identified in the mode. The degree of differentiation is inversely proportional to the frequency of eruptions.The lavas of West Maui volcano are divided into the Wailuku volcanic series
