    The treatment of dental surface using different lasers to prevent dental caries has been studied for several on last years. The purpose of this in vitro study was to evaluate the morphological changes on dentin surface from pulpal wall of cavity preparations performed by high-speed drill, treated with 2,26% fluoride varnish (Duraphat) and Er:YAG laser, and then submitted after receiving or not to EDTA 15% treatment. Twenty Class V cavities were performed on ten humans molars. The specimens were randomly divided in to 4 groups: group 1- treatment with Duraphat followed by Er:YAG laser irradiation (120 mJ/ 4 Hz); group 2: Er:YAG laser irradiation, same parameters, followed by Duraphat treatment; group 3- same group 1 followed by immersion in EDTA (5 min); group 4 - same as group 2 followed by immersion in EDTA (5 min). The specimens were processed for SEM analysis. The micrographs showed that Duraphat treatment promoted morphological changes on dentin, closing dentinal tubules; the specimens treated by Duraphat and Er:YAG laser and immersed in EDTA (group 3) showed homogeneous surface, closed and protected dentinal tubules, maintenance of the fluoride varnish on the dentin surface and around the dentinal tubules, showing feasible and efficiency of these therapies the feasibility.(author)

    The goal of this work was a development of an algorithm for the Truncated Plurigaussian Stochastic Simulation and its validation in a complex geologic model. The reservoir data comes from Aux Vases Zone at Rural Hill Field in Illinois, USA, and from the 2D geological interpretation, described by WEIMER et al. (1982), three sets of samples, with different grid densities ware taken. These sets were used to condition the simulation and to refine the estimates of the non-stationary matrix of facies proportions, used to truncate the gaussian random functions (RF). The Truncated Plurigaussian Model is an extension of the Truncated Gaussian Model (TG). In this new model its possible to use several facies with different spatial structures, associated with the simplicity of TG. The geological interpretation, used as a validation model, was chosen because it shows a set of NW/SE elongated tidal channels cutting the NE/SW shoreline deposits interleaved by impermeable facies. These characteristics of spatial structures of sedimentary facies served to evaluate the simulation model. Two independent gaussian RF were used, as well as an 'erosive model' as the truncation strategy. Also, non-conditional simulations were proceeded, using linearly combined gaussian RF with varying correlation coefficients. It was analyzed the influence of some parameters like: number of gaussian RF,correlation coefficient, truncations strategy, in the outcome of simulation, and also the physical meaning of these parameters under a geological point of view. It was showed, step by step, using an example, the theoretical model, and how to construct an algorithm to simulate with the Truncated Plurigaussian Model. The conclusion of this work was that even with a plain algorithm of the Conditional Truncated Plurigaussian and a complex geological model it's possible to obtain a usefulness product. (author)

    1997-03-01

    Full Text Available Tendo em vista a relevância da prevenção das doenças cardiovasculares, este artigo visa discutir alguns aspectos relativos à prevenção cardíaca primária e secundária a partir de um programa de condicionamento físico especializado. A prática da atividade física regular é utilizada tanto para a prevenção como para a reabilitação das doenças cardiovasculares. Um bom programa de condicionamento físico produz alterações fisiológicas crônicas nos sistemas cardiovascular e neurovegetativo e na secreção hormonal, constituindo expressivas modificações no que diz respeito à prevenção, estabilização e até regressão do quadro degenerativo das cardiopatias. A supervisão do paciente durante a sessão de condicionamento físico é essencial, pois a incidência de complicações cardiovasculares é maior nestes, quando comparados com adultos aparentemente saudáveis; com isso, a segurança e a qualidade do programa ficam salvaguardadas. Um aspecto muito importante é a necessidade da prescrição de exercício individualizada, tanto na prevenção primária como nas três fases de prevenção secundária. Essa prescrição deve respeitar os princípios do treinamento físico e os componentes básicos do programa: freqüência e duração, que são valores absolutos, e a intensidade, que é o fator crítico da prescrição, pois é relativa e envolve fatores como diferença entre os sexos, nível de aptidão física e idade

    Full Text Available Pterogyne nitens Tul. é conhecida popularmente como amendoim do campo, é uma espécie arbórea, heliófita, secundária inicial que se regenera intensamente em áreas abertas e pastagens. Pode ser empregada como espécie ornamental e na reposição de mata ciliar, em locais sujeitos a inundações periódicas, em sítios arenosos e degradados. O condicionamento é uma técnica pós-colheita usada com o objetivo de aumentar a velocidade de germinação, emergência, bem como ampliar a tolerância a vários tipos de estresse. O objetivo deste trabalho foi avaliar a eficiência do condicionamento com ou sem secagem posterior em aumentar a resistência a diferentes tipos de estresse. As sementes selecionadas foram escarificadas com ácido sulfúrico durante 15 min. e depois condicionadas em água destilada e soluções de manitol -0,5 e -1,0 MPa durante 24h a 10oC. Para cada solução de condicionamento, o lote de sementes foi dividido em dois grupos, um dos quais foi seco até atingir o teor de umidade apresentado antes do condicionamento, e o segundo foi imediatamente usado nos testes. Os diferentes grupos de sementes foram expostos ao envelhecimento acelerado (100% U.R. sob 35 e 40oC, ao estresse térmico (24h a 60 e 70oC e o teste de exaustão (24h submersos a 10 e 27oC. Para todos os testes foram utilizadas quatro repetições de 25 unidades e os dados de porcentagem e velocidade de germinação foram submetidos à análise de variância e ao teste de Tukey. Com o aumento da intensidade do estresse houve diminuição na germinação e no vigor das sementes, que as diferentes formas de condicionamento não reverteram. Em geral, o condicionamento com o uso manitol a -1,0 MPa diminuiu a qualidade fisiológica das sementes e, soluções a -0,5 MPa ou água destilada aumentaram a porcentagem e/ou velocidade de germinação de sementes submetidas aos diferentes tipos de estresse.

    The purpose of this study was to evaluate (in vivo) the effects of low-intensity Arsenide Gallium Aluminium laser application post-cavity preparation class 1. Six patients with bilateral pre-molars and molars indicated to extraction for orthodontics aim were selected. Four samples of these teeth underwent cavity preparation with deep from medium to high and two samples underwent cavity preparation from high to pulp expositions. The samples were constituted of two teeth of the same patient and received different treatments. One of the teeth underwent laser exposition and the other one was maintained as control, before restorative procedure with polycarboxylate cement. A diode laser ({lambda}=650 nm), output power 30 mW and fluencies of 1,8 J/cm{sup 2} and 2,7 J/cm{sup 2} in pre-molars and molars, respectively, was used for irradiation with repetition rate of 18 Hz in interrupted continuous wave mode. After seven days, the teeth were extracted and processed histologically with HE to verify morphological changes in the pulpy tissue. The four samples, which cavity preparation and restorative material were not in contact with the pulp, did not show histological differences between irradiated and non-irradiated teeth. Both of them presented the same characteristics of normality. The two samples with exposed pulpy tissue showed different results. The irradiated teeth presented no or slight inflammatory signs when compared to the control samples, which showed abscess in the coronary pulp interior and intense inflammatory infiltrated. These results suggest that the laser irradiation can be used as a therapeutic modality in clinical trials, in the conditions employed in this study. (author)

    Full Text Available The aim of this study was to determine whether goats could be averted from consuming Mascagnia rigida, a toxic plant found in the semiarid region of northeastern Brazil. Fourteen male goats not previously familiarized to M. rigida were randomly allocated to two treatment groups: control (treated with 5.5mL water orally by a drenching gun and lithium group (treated with 100mg LiCl/kg body weight orally by a drenching gun. For conditioning, goats were allowed to feed on M. rigida leaves for 15 min, followed by LiCl or water administration. The time spent on eating M. rigida leaves was measured. The conditioning was repeated daily until the LiCl-treated goats stopped eating M. rigida. On the 10th, 17th, and 24th day after conditioning, extinction trials of the M. rigida aversion were performed in goats by using single-choice tests. There was no difference between the two treatment groups with respect to the consumption of M. rigida on the first day of aversion conditioning, however, controls ingested increasing amounts of the plant on consecutive conditioning days. On the second day, five out of the seven goats in the lithium group did not eat the leaves, but on the third day, all the goats in the lithium group did not ingest M. rigida. This aversion persisted throughout all evaluated days. This indicates that goats can be easily conditioned by using lithium chloride to avoid eating M. rigida temporarily.O objetivo do presente estudo foi determinar se os caprinos podem desenvolver aversão ao consumo de Mascagnia rigida, uma planta tóxica encontrada na região semi-árida do nordeste brasileiro.

Vinte e quatro horas após, para avaliar se os tempos de pré-condicionamento influenciam o aparecimento de translocação bacteriana, amostras de linfonodos mesentéricos, fígado e baço foram coletadas em condições estéreis, para quantificação de unidades formadoras de colônias bacterianas por grama de tecido (UFC/g. Sangue foi coletado para dosagem de citocinas. RESULTADOS: No grupo I/R, o total de UFC/g em linfonodos mesentéricos, baço, fígado, bem como, a dosagem sérica de TNF-a, IL-1b e IL-6 foram significativamente maiores do que nos demais grupos (p<0,05. Pré-condicionamento de 15 minutos atenuou significativamente a BT e as citocinas séricas, comparando com os outros tempos de pré-condicionamento (p<0,05. CONCLUSÃO: Nossos dados sugerem o pré-condicionamento como fator-chave para reduzir translocação bacteriana em I/R intestinal. Numa escala de dois a 15 minutos, o melhor tempo de pré-condicionamento isquêmico para a atenuação da translocação bacteriana foi 15 minutos.

Estes foram divididos em dois grupos, experimental (n= 12 e controle (n=12. RESULTADOS: Concentrações de adiponectina após 12 semanas tiveram declínio significativo em ambos os grupos em comparação com o nível basal (p < 0,05. VO2 pico, flexibilidade, força, endurance de abdominais e agilidade aumentaram significativamente no grupo experimental comparado com o grupo controle (p < 0.05. Foi evidenciado que após destreinamento de 4 semanas, a adiponectina sérica não se alterou significativamente no grupo experimental e que condicionamento físico benéfico foi gradualmente diminuído. CONCLUSÃO: Nossos resultados sugerem que os efeitos benéficos do exercício físico no condicionamento são temporários. Uma vez que o processo de adaptação é reversível, parece que as concentrações de adiponectina foram inevitavelmente afetadas pelas alterações morfológicas e hormonais que ocorreram durante a puberdade em meninos.

    The aim of this paper is to evaluate whether the UK regional electricity companies (RECs) has used total quality management (TQM) as a &apos;'push'&apos; or as a &apos;'pull'&apos; change methodology. &apos;'Push'&apos; is the operational improvement role of TQM; &apos;'pull'&apos; is the strategic or direction giving, improvement role of TQM. Following the onset of privatisation in 1990 there has been evidence of the RECs adopting TQM in both &apos;'push'&apos; and &apos;'pull'&apos; methodologies with varying degrees of success. An evaluation of the change processes involved will enable improved change models to be developed leading to increased business effectiveness in this 30 billion pounds sterling industry. Other possible benefits include the possible generalisations to other utilities such as water, roads, gas and telecoms. The research methodology includes a comparative case study analysis of five RECs, which have used TQM as their overarching approach to change. One of the cases is analysed to a more in-depth level based on the multiple case findings. The findings indicate that the &apos;'push-pull'&apos; analysis enables the full range of TQM activities to be evaluated in the RECs studied. Overall, there is a need to have a balanced portfolio of operational or &apos;'push'&apos;-based TQM activity that is driven by strategic or &apos;'pull'&apos; based TQM planning and activity.

    High-energy radiography is used traditionally for the detection of defects in the thick-walled, bulky components. It is also used for testing the integrity of components for civil and security related applications (containers). The combination of high-energy emitters with digital detector arrays or line cameras allows test procedures in a shorter time compared to film or higher contrast sensitivity. The high-energy X-ray laboratory HEXYLab BAM is a joint laboratory in which future users, manufacturers and scientists can initiate and develop joint development projects. The new universal manipulation system HEXYTech forms the engineering and technical base for the most diverse requirements in HEXYLab (High Energy X-raY Lab.). With a total of 13 rotary and linear axes the diverse trajectories for tube, object and detector can be programmed. So large objects with complex geometries can be examined. 2D and 3D images can be measured by simple radiography, and laminography and computed tomography. The general rules for the application of high energy radiography with digital detectors (imaging plates, Digital detector arrays) were determined within the framework of the European project &apos;'HEDRad'&apos; (High Energy Digital Radiography) and included in the standard DIN EN ISO 17636-2.

    Production and up-concentration of naturally occurring radioactive material (NORM) in the petroleum industry has attracted steadily increasing attention during the last 15 years. Most production engineers today associate this radioactivity with precipitates (scales) and sludges in production tubing, pumps, valves, separators, settling tanks etc., wherever water is being transported or treated. {sup 226}Ra and {sup 228}Ra are the most well known radioactive constituents in scale. Surprisingly little known is the radioactive contamination by {sup 210}Pb and progeny {sup 210}Bi and {sup 210}Po. These are found in combination with {sup 226}Ra in ordinary scale, often in layer of non-radioactive metallic lead in water transportation systems, but also in pure gas and condensate handling systems &apos;'unsupported'&apos; by {sup 226}Ra, but due to transportation and decay of the noble gas {sup 222}Rn in NG/LNG. This latter contamination may be rather thin, in some cases virtually invisible. When, in addition, the radiation energies are low enough for not being detectable on the equipment outer surface, its existence has for most people in the industry been a secret. The report discusses transportation and deposition mechanisms, detection methods and provides some examples of measured results from the North Sea on equipment sent for maintenance. It is concluded that a regular measurement program for this type of contamination should be mandatory under all dismantling processes of transportation and fluid handling equipment for fluids and gases offshore and onshore.

    Full Text Available Important factors affecting seed priming have not been extensively reported in muskmelon (Cucumis melo L. studies. The optimization of the seed priming technique becomes very important at the commercial scale. Little information has been reported on seedling development of muskmelon subsequent to seed priming. Seeds of muskmelon were primed in darkness at 25°C in different solutions and three osmotic potentials. Seeds were also primed with and without aeration during different periods. In relation to osmotic solutions, an osmotic potential around -1.30 MPa is most adequate for muskmelon priming. Salt solutions gave better germination rate but were deleterious for seed germination, especially at higher osmotic potentials. Aeration of the soaking salt solution gave faster germination at 17°C, and because of the early germination, these treatments probably presented a better seedling development. Deleterious effect on total seed germination was observed for long soaking periods with aeration. Fungal growth increased on seeds primed in aerated solutions. Seeds from priming treatments had a better germination rate and seedling development under 17 and 25°C.Importantes fatores afetando o condicionamento osmótico não têm sido extensivamente relatados em sementes de melão (Cucumis melo L..

    Oil producers are increasingly under pressure to produce their product in an environmentally sound manner. Releases to the environment are undesirable and, where permitted to make such releases, oil producers should minimise their environmental impact. The bulk of treatment chemicals designed to improve separation and provide clean water for disposal can themselves be harmful to the environment and must conform to very stringent rules to be considered environmentally acceptable, or &apos;'green'&apos;. Here we present data on the development of a green demulsifier for Statoil&apos;s Gullfaks &apos;'A'&apos; platform, which not only meets the very stringent regulations but also exhibits a significant improvement in product performance. While the&apos;&apos;bottle test&apos;&apos; remains the industry standard method for selecting demulsifiers, in recent years the &apos;&apos;mini trial&apos;&apos; method for product selection has gained favour. We describe using a combination of both methods for the development of the novel demulsifier technology described here. (Author) (tk)

    Full Text Available O condicionamento fisiológico compreende técnicas que estimulam a germinação e contribuem para reduzir a sensibilidade de sementes e de plântulas a estresses. Efeitos sobre a germinação e a emergência de plântulas têm sido amplamente estudados, mas a influência sobre o comportamento das plantas em campo ainda não é totalmente conhecida. Esta pesquisa foi conduzida com o objetivo principal de verificar efeitos do hidrocondicionamento sobre a germinação, emergência de plântulas, desenvolvimento das plantas e produção de couve-flor. Sementes das cultivares de couve-flor Sharon e Teresópolis Gigante, representados por três lotes, foram hidrocondicionados em papel-toalha, a 20ºC, até atingir 38% de água ('Sharon' ou 41% ('Teresópolis Gigante'. Posteriormente, foram secadas em estufa, a 28-30ºC e 45-55% de umidade relativa, até atingirem teores de água de 7,5% a 7,9%. O potencial fisiológico das sementes foi determinado em laboratório, avaliando-se a percentagem e a velocidade de germinação. Posteriormente, efetuou-se a semeadura em bandejas de poliestireno; o transplante para o campo foi efetuado quando as plantas atingiram estádio de quatro folhas definitivas (30 dias após a semeadura. Determinou-se a velocidade e percentagem de emergência das plântulas aos 14 dias após a semeadura; a altura e a massa seca das plantas foram avaliadas aos 14; 30; 56; 74 e 84 dias e o diâmetro médio da cabeça e a produção final, aos 110 dias. O hidrocondicionamento pode favorecer a velocidade de germinação e de emergência de plântulas, mas esses efeitos não são suficientes para persistir durante o desenvolvimento das plantas e afetar a produção final.Priming treatment usually promotes rapid and uniform germination and increases tolerance to different stress conditions. Post-treatment effects on seed germination and seedling emergence have been extensively studied but information of plant performance is less available

    Quasar feedback in the form of powerful outflows is invoked as a key mechanism to quench star formation in galaxies, preventing massive galaxies to overgrow and producing the red colors of ellipticals. On the other hand, some models are also requiring &apos;'positive'&apos; active galactic nucleus feedback, inducing star formation in the host galaxy through enhanced gas pressure in the interstellar medium. However, finding observational evidence of the effects of both types of feedback is still one of the main challenges of extragalactic astronomy, as few observations of energetic and extended radiatively driven winds are available. Here we present SINFONI near infrared integral field spectroscopy of XID2028, an obscured, radio-quiet z = 1.59 QSO detected in the XMM-COSMOS survey, in which we clearly resolve a fast (1500 km s{sup –1}) and extended (up to 13 kpc from the black hole) outflow in the [O III] lines emitting gas, whose large velocity and outflow rate are not sustainable by star formation only. The narrow component of Hα emission and the rest frame U-band flux from Hubble Space Telescope/Advanced Camera for Surveys imaging enable to map the current star formation in the host galaxy: both tracers independently show that the outflow position lies in the center of an empty cavity surrounded by star forming regions on its edge. The outflow is therefore removing the gas from the host galaxy (&apos;&apos;negative feedback&apos;&apos;), but also triggering star formation by outflow induced pressure at the edges (&apos;&apos;positive feedback&apos;&apos;). XID2028 represents the first example of a host galaxy showing both types of feedback simultaneously at work.

  7. Switzerland as Europe&apos;s &apos;'battery'&apos;. Wishful dream or reality?

    International Nuclear Information System (INIS)

    There are plans for Swiss pumped hydrostorage systems to absorb large quantities of excess electricity from European wind and solar power generation. Model-based analyses have shown however that &apos;'Europe&apos;s battery&apos;&apos;, as Switzerland would like to see itself, will not be needed until the middle of this century. Even if all extension projects currently in progress should be completed, Switzerland will not have sufficient pump capacity or import capacity to absorb large amounts of excess electricity. Furthermore, the primary means of making storage capacity available for import electricity would be to reduce reservoir power plant capacity. In view of all this Switzerland&apos;s hopes for a role as a major European electricity storage provider appear somewhat exaggerated even in the long-term perspective.

    Full Text Available Summary Background Narcolepsy is a common neuropsychiatric disorder characterized by increased daytime sleepiness, cataplexy and hypnagogic hallucinations. Deficiency of the hypocretin neurotransmitter system was shown to be involved in the pathogenesis of narcolepsy in animals and men. There are several hints that neurodegeneration of hypocretin producing neurons in the hypothalamus is the pathological correlate of narcolepsy. The ApoE4 allele is a major contributing factor to early-onset neuronal degeneration in Alzheimer disease and other neurodegenerative diseases as well. Methods To clarify whether the ApoE4 phenotype predisposes to narcolepsy or associates with an earlier disease onset, we have genotyped the ApoE gene in 103 patients with narcolepsy and 101 healthy controls. Results The frequency of the E4 allele of the ApoE gene was 11% in the patient and 15% in the control groups. Furthermore, the mean age of onset did not differ between the ApoE4+ and ApoE4- patient groups. Conclusion Our results exclude the ApoE4 allele as a major risk factor for narcolepsy.

    When regulators put forward new economic or regulatory policies, there is a need to compare the costs and benefits of these new policies to existing policies and other alternatives to determine which policy is most cost-effective. For command and control policies, it is quite difficult to compute costs, but for more market-based policies, economists have had a great deal of success employing general equilibrium models to assess a policy&apos;s costs. Not all cost measures, however, arrive at the same ranking. Furthermore, cost measures can produce contradictory results for a specific policy. These problems make it difficult for a policy-maker to determine the best policy. For a cost measures to be of value, one would like to be confident of two things. First one wants to be sure whether the policy is a winner or loser. Second, one wants to be confident that a measure produces the correct policy ranking. That is, one wants to have confidence in a policy measure&apos;s ability to correctly rank policies from most beneficial to most harmful. This paper analyzes empirically these two properties of different costs measures as they pertain to assessing the costs of the carbon abatement policies, especially the Kyoto Protocol, under alternative assumptions about implementation.

    &apos;&apos;The Build&apos;&apos; is the infrastructure needed to convert software from source code to usable form. It is intimately tied to the software it supports, knowing about every file and automating every transformation needed to produce a working program. Every developer knows that a project spends some labor overhead on &apos;&apos;the build.&apos;&apos; How big is this hidden overhead? According to 34 scientific software developers we surveyed at Lawrence Livermore National Labs, among colleagues at other DOE labs, and a handful of academics the &apos;'perceived'&apos; overhead averages around 12%. Individual cases of 20% to 30% were not uncommon. In one project claiming a 20% overhead, we found supporting evidence by combing through their CVS repository.

    We discuss a novel approach to &apos;'weighing'&apos; the Milky Way (MW) dark matter halo, one that combines the latest samples of halo stars selected from the Sloan Digital Sky Survey (SDSS) with state of the art numerical simulations of MW analogs. The fully cosmological runs employed in the present study include &apos;'Eris'&apos;, one of the highest resolution hydrodynamical simulations of the formation of a M{sub vir} = 8 Multiplication-Sign 10{sup 11} M{sub Sun} late-type spiral, and the dark-matter-only M{sub vir} = 1.7 Multiplication-Sign 10{sup 12} M{sub Sun} &apos;&apos;Via Lactea II&apos;&apos; (VLII) simulation. Eris provides an excellent laboratory for creating mock SDSS samples of tracer halo stars, and we successfully compare their density, velocity anisotropy, and radial velocity dispersion profiles with the observational data. Most mock SDSS realizations show the same &apos;&apos;cold veil&apos;&apos; recently observed in the distant stellar halo of the MW, with tracers as cold as {sigma}{sub los} Almost-Equal-To 50 km s{sup -1} between 100 and 150 kpc. Controlled experiments based on the integration of the spherical Jeans equation as well as a particle tagging technique applied to VLII show that a &apos;'heavy'&apos; M{sub vir} Almost-Equal-To 2 Multiplication-Sign 10{sup 12} M{sub Sun} realistic host produces a poor fit to the kinematic SDSS data. We argue that these results offer added evidence for a &apos;'light'&apos;, centrally concentrated MW halo.

    Almost three years after the Fukushima events, the nuclear industry has shown its capacity to respond to first additional safety requirements and continues working closely with the regulators and involved stakeholders for further improvements. Continued growth is still anticipated and several international organizations have confirmed 2035 scenarios close to or above 600 GWe of installed nuclear capacity. Securing and optimizing the fuel cycle is crucial to ensure the sustainability of such a nuclear program in the medium term. Rethinking fuel cycle schemes is also decisive to prepare long term transitions to next generations of reactors. R&D and Innovation shall remain a cornerstone of this sustainable development. Countries with significant or growing nuclear fleets have confirmed their commitment or plans to recycle. This is notably the case in China, France, India, Japan, the Netherlands, South Korea, and the Russian federation.

    The distinctive cometary X-ray morphology of the recently discovered massive galaxy cluster &apos;&apos;El Gordo&apos;&apos; (ACT-CT J0102–4915; z = 0.87) indicates that an unusually high-speed collision is ongoing between two massive galaxy clusters. A bright X-ray &apos;'bullet'&apos; leads a &apos;'twin-tailed'&apos; wake, with the Sunyaev-Zel&apos;dovich (SZ) centroid at the end of the northern tail. We show how the physical properties of this system can be determined using our FLASH-based, N-body/hydrodynamic model, constrained by detailed X-ray, SZ, and Hubble lensing and dynamical data. The X-ray morphology and the location of the two dark matter components and the SZ peak are accurately described by a simple binary collision viewed about 480 million years after the first core passage. We derive an impact parameter of ≅300 kpc, and a relative initial infall velocity of ≅2250 km s{sup –1} when separated by the sum of the two virial radii assuming an initial total mass of 2.15 × 10{sup 15} M {sub ☉} and a mass ratio of 1.9. Our model demonstrates that tidally stretched gas accounts for the northern X-ray tail along the collision axis between the mass peaks, and that the southern tail lies off axis, comprising compressed and shock heated gas generated as the less massive component plunges through the main cluster. The challenge for ΛCDM will be to find out if this physically extreme event can be plausibly accommodated when combined with the similarly massive, high-infall-velocity case of the Bullet cluster and other such cases being uncovered in new SZ based surveys.

    The device and X-ray measurement technique, used for the elemental analysis of Venerus&apos; rocks by the &apos;&apos;Venera-13&apos;&apos; and &apos;&apos;Venera-14&apos;&apos; space probes, are described. The X-ray fluorescence spectrometer device, characteristics of Fe/sup 55/ and Pu/sup 238/ radioisotope sources, used in the device, the proportional counter and the structural flowsheet of the pulse amplitude analyzer, is briefly represented. Venerus&apos; rock is sampled by a special coring tool, transported through the sluice port into the lander and irradiated by radioisotope sources. The excited fluorescence is recorded by a 256-channel spectrometer. The information is transmitted to the Earth telemetrically. The devices of both landers operate reliably. The chemical composition of the rock samples is determined as a result of these experiments.

    With a population of over 1.3 billion people, demand for renewable energy is expected to grow to a USD $12 billion market in the near term. Under Renewable Energy Law (REL) in February 2005 in the People&apos;s Republic of China (PRC) passed by the National Congress, renewable energy projects will be able to receive a range of financial incentives starting in 2006, which will more than double the PRC current renewable energy generation from 7% to 15% by 2020. Most of the increase will be in hydroelectric generated power. Nonetheless, the nation and especially the provinces are moving rapidly to develop a wide range of renewable energy generation including solar, wind, geothermal and run of the river. Because China practices &apos;&apos;social capitalism&apos;&apos; as expressed in it&apos;s recurrent Five Year National Plans since 1999, the national government and all the provinces have programs, unlike many western and industrialized nations, to &apos;'plan'&apos; and provide for infrastructures. This paper concerns only the energy infrastructure sector and renewable energy generation in particular. The planning process includes financial incentives and investments which are a major part of the Chinese law focused on &apos;&apos;encouraging foreign investment industries&apos;&apos;. The key part of the law is to guarantee long-term power purchase agreements with state owned and controlled &apos;'utilities'&apos;. In short, China may have gotten the economics of the energy sector correct in its concern for planning and finance. The paper develops these energy infrastructure ideas along with the legal and financial requirements as &apos;'lessons'&apos; learned from the USA and especially California. These lessons now apply to China and allow it to learn from the American mistakes. Empirical data will be drawn from work done in China that examine the renewable energy generation and infrastructures and hence allow the RPC and its

    This study aims to identify the premature synostosis of &apos;'major'&apos; and &apos;'minor'&apos; sutures of the four &apos;&apos;sutural arches&apos;&apos; of the skull and to perform a morphometric analysis in children with syndromic craniosynostosis in order to evaluate changes in the skull base linked with premature suture synostosis. We reviewed multiplanar high-resolution CT images, implemented with 3D reconstructions, from 18 patients with complex syndromic craniosynostosis and compared them with 18 age-matched healthy subjects. We assessed the calvarial sutures and their extension to the skull base, and then we correlated specific types of synostosis with the size, shape and symmetry of the cranial fossae. We found a marked asymmetry of the skull base growth in all patients. The synostotic involvement around the coronal ring caused a reduction in the growth of the anterior and middle fossae. The size of the posterior cranial fossa was related not only to &apos;'major'&apos; but also to &apos;'minor'&apos; suture synostosis of the lambdoid and parieto-squamosal arches. Changes in the skull base and craniofacial axis symmetry are due to structural and functional relationships between &apos;'major'&apos; and &apos;'minor'&apos; skull sutures, suggesting a structural and functional relationship between the neurocranium and basicranium. The early recognition of prematurely closed skull base sutures may help clinicians and neurosurgeons to establish correct therapeutic approaches. (orig.)

Consiste na indução de breves períodos de isquemia seguidos de reperfusão, para tornar o órgão resistente a períodos mais longos de isquemia. Nesta investigação estudamos sua eficácia na proteção das lesões de isquemia-reperfusão hepáticas em ratos. Utilizaram-se 40 animais divididos em grupo Controle (C; grupo Shunt (S, submetido a exposição da cavidade abdominal por 95’; grupo Isquemia (I, submetido a exposição da cavidade abdominal por 10’, isquemia de 80’ e reperfusão de 5’; e grupo Pré-condicionamento (PC, em que realizamos isquemia de 5’, reperfusão de 5’, nova isquemia de 80’ e reperfusão de 5’. As enzimas hepáticas e o potencial elétrico da membrana mitocondrial interna (MMI foram analisados. Os resultados mostraram aumento nos níveis de ALT,AST e LDH em todos os grupos em relação ao controle e nos grupos I e PC em relação ao grupo S. Houve diminuição significativa do potencial elétrico da MMI no grupo Isquemia em relação aos demais. O aumento nos níveis das enzimas hepáticas nos grupos Isquemia e Pré-condicionamento em relação ao grupo Shunt pode ser atribuído a perda da integridade da membrana citoplasmática provocada pela isquemia de 80’ e reperfusão de 5’. A diminuição do potencial elétrico da membrana mitocondrial interna no grupo Isquemia em relação aos demais pode estar relacionada a lesão da MMI e perda do gradiente de prótons transmembrana. O pré-condicionamento isquêmico atenua essas lesões provavelmente pelo consumo mais lento do ATP durante a isquemia.

    In order to obtain three isoforms of apolipoprotein E (apoE), the cDNA encoding apoE3 was obtained by RT-PCR from normal human liver tissue. Site-directed mutagenesis was used to obtain the cDNAs encoding apoE2 and apoE4 isoforms. The 3 cDNAs were subcloned into vector pGEM-3Z and verified by DNA sequencing. The expression recombinant which can express the target protein as a (His) 6-tagged fusion was constructed by subcloning apoE cDNA into vector pT7-PL. The purified proteins were gained by Ni-NTA column. The SDS-PAGE results revealed the 6 His fusion proteins (apoE2, apoE3 and apoE4) were correctly expressed and purified successfully.

    Assess extensor carpi ulnaris (ECU) tendon position in the ulnar groove, determine the frequency of tendon &apos;'dislocation'&apos; with the forearm prone, neutral, and supine, and determine if an association exists between ulnar groove morphology and tendon position in asymptomatic volunteers. Axial proton density-weighted MR was performed through the distal radioulnar joint with the forearm prone, neutral, and supine in 38 asymptomatic wrists. The percentage of the tendon located beyond the ulnar-most border of the ulnar groove was recorded. Ulnar groove depth and length was measured and ECU tendon signal was assessed. 15.8 % of tendons remained within the groove in all forearm positions. In 76.3 %, the tendon translated medially from prone to supine. The tendon &apos;'dislocated'&apos; in 0, 10.5, and 39.5 % with the forearm prone, neutral and supine, respectively. In 7.9 % prone, 5.3 % neutral, and 10.5 % supine exams, the tendon was 51-99 % beyond the ulnar border of the ulnar groove. Mean ulnar groove depth and length were 1.6 and 7.7 mm, respectively, with an overall trend towards greater degrees of tendon translation in shorter, shallower ulnar grooves. The ECU tendon shifts in a medial direction when the forearm is supine; however, tendon &apos;'dislocation'&apos; has not been previously documented in asymptomatic volunteers. The ECU tendon medially translated or frankly dislocated from the ulnar groove in the majority of our asymptomatic volunteers, particularly when the forearm is supine. Overall greater degrees of tendon translation were observed in shorter and shallower ulnar grooves. (orig.)

    The usefulness of radionuclear scanning in the treatment of 18 patients with necrotizing progressive &apos;'malignant'&apos; external otitis is discussed. A Tc 99-m bone scan, a valuable test since results are positive in early cases of osteomyelitis of the temporal bone and base of skull, showed increased uptake in all 18 patients. In 6 patients, Ga-67 citrate scans were obtained at the start of therapy and at 5-6 week intervals thereafter. The serial gallium scans were useful in evaluating the effectiveness of therapy since the uptake decrease with control of infection.

    To scrutinize the disorders caused by human mutant apoE7/apoE4, human apoE4 and E7 transgenic mice were established with microinjection technique to examine molecular genetic phenomena in vivo. The integration and expression of h-apoE mutant genes in transgenic mice were determined with Southern blot, Northern blot and ELISA. The current studies indicated that the transgenes and the phenotypes regarding expression of transgenes could be transmitted stably in transgenic lines. The levels of serum lipid in transgenic mice showed the characteristics of hyperlipidemia. Besides, behavior tests demonstrated the degeneration of learning and memory in transgenic mice. Short life span was observed in 2 transgenic lines. After fed with high lipid food high serum lipid was found both in normal and transgenic mice, but their mechanism regulating lipid metabolism was different. It was also verified that the human apoE mutants located at either N-terminal or C-terminal had the same pathogenesis regarding disorders of lipid metabolism in murine.

    Global sea-surface temperature maps show that mass coral-reef bleaching episodes between 1983 and 1991 followed positive anomalies more than 1 deg C above long-term monthly averages (&apos;&apos;hot spots&apos;&apos;) during the preceding warm season. Irregular formation, movement, and disappearance of hot spots make their detailed long-term prediction impossible, but they can be tracked in real time from satellite data. Monitoring of ocean hot spots and of coral bleaching is needed if the Framework Convention of Climate Change is to meet its goal of protecting the most temperature sensitive ecosystems. 47 refs, 3 figs

    For decades, there has been a heated debate about whether or not nuclear power plants contribute to childhood cancer in their respective neighbourhoods, with statisticians testifying on both sides. The present paper points to some flaws in the pro-arguments, taking a recent study prepared for the political party &apos;&apos;Buendnis 90 / Gruene&apos;&apos; as a specimen. Typical mistakes include an understatement of the size of tests of significance, disregard of important covariates and extreme reliance on very few selected data points.

  10. The &apos;&apos;Kinetic Stabilizer&apos;&apos;: A Simpler Tandem Mirror Confinement?

    Post, R.F.

    2000-06-15

    In the search for better approaches to magnetic fusion it is important to keep in mind the lessons learned in the 50 years that fusion plasma confinement has been studied. One of the lessons learned is that &apos;'closed'&apos; and &apos;'open'&apos; fusion devices differ fundamentally with respect to an important property of their confinement, as follows: Without known exception closed systems such as the tokamak, the stellarator, or the reversed-field pinch, have been found to have their confinement times limited by non-classical, i.e., turbulence-related, processes, leading to the requirement that such systems must be scaled-up in dimensions to sizes much larger than would be the case in the absence of turbulence. By contrast, from the earliest days of fusion research, it has been demonstrated that open magnetic systems of the mirror variety can achieve confinement times close to that associated with classical, i.e., collisional, processes. While these good results have been obtained in both axially symmetric fields and in non-axisymmetric fields, the clearest cases have been those in which the confining fields are solenoidal and axially symmetric. These observations, i.e., of confinement not enhanced by turbulence, can be traced theoretically to such factors as the absence of parallel currents in the plasma, and to the constraints on particle drifts imposed by the adiabatic invariants governing particle confinement in axisymmetric open systems. In the past the MHD instability of axially symmetric open systems has been seen as a barrier to their use. However, theory predicts MHD-stable confinement is achievable if sufficient plasma is present in the &apos;&apos;good curvature&apos;&apos; regions outside the mirrors. This theory has been confirmed by experiments on the Gas Dynamic Trap mirror-based experiment at Novosibirsk, In this paper a new way of exploiting this stabilizing principle, involving creating a localized &apos;&apos

    The analysis of criteria of division of radioactive wastes (RAW) of object &apos;'Ukryttya'&apos; is executed on short-lived and long-lived, and their activity. It is shown that to short-lived RAW underactive belong and insignificant part of me-dium-activity waste. Hundreds of thousands of m3 of RAW on overhead marks belong to long-lived medium-activity wastes. Organization of burial place of such wastes in stable geological structures is an unrealistic task. It is suggested to create the special depository for such RAW, and buried in stable geological structures high-activity wastes only

    Full Text Available A large number of Himalayan glacier catchments are under the influence of humid climate with snowfall in winter (November–April and South-West monsoon in summer (June–September dominating the regional hydrology. Such catchments are defined as &apos;&apos;Himalayan catchment&apos;&apos;, where the glacier melt water contributes to the river flow during the period of annual high flows produced by the monsoon. Other two major glacio-hydrological regimes of the Himalaya are winter snow dominated Alpine catchments of the Kashmir and Karakoram region and cold-arid regions of the Ladakh mountain range. Factors influencing the river flow variations in a &apos;&apos;Himalayan catchment&apos;&apos; were studied in a micro scale glacier catchment in the Garhwal Himalaya, covering an area of 77.8 km2. Discharge data generated from three hydrometric stations established at different altitudes of the Din Gad stream during the summer ablation period of 1998, 1999, 2000, 2001, 2003 and 2004. These data has been analysed along with winter/summer precipitation, temperature and mass balance data of the Dokriani glacier to study the role of the glacier and precipitation in determining the runoff variations along the stream continuum from the glacier snout to 2360 m a.s.l. Study shows that the inter-annual runoff variations in a &apos;&apos;Himalayan glacier catchment&apos;&apos; is directly linked with the precipitation rather than mass balance changes of the glacier. Study suggest that warming induced initial increase of glacier degraded runoff and subsequent decline is a glaciers mass balance response and cannot be translated as river flow response in a &apos;&apos;Himalayan catchment&apos;&apos; as suggested by the IPCC, 2007. Study also suggest that the glacier runoff critically influence the headwater river flows during the years of low summer discharge and proposes that the Himalayan catchment could experience higher river flows and positive

    Waste managers are increasingly expected to provide good security for the hazardous materials they marshal. Good security requires, among other things, effective tamper and intrusion detection. We have developed and demonstrated a new method for tamper and intrusion detection which we call the &apos;&apos;town crier method&apos;&apos;. It avoids many of the problems and vulnerabilities associated with traditional approaches, and has significant advantages for hazardous waste transport. We constructed two rudimentary town crier prototype systems, and tested them for monitoring cargo inside a truck. Preliminary results are encouraging.

    The final disposal of nuclear wastes is called &apos;'messy'&apos; or &apos;'wicked'&apos; in the political science literature. The highly complicated problems are characterized by a number of features such as intra- and inter-generational aspects and ethical questions. In the case of stakeholders the differences concern ideologies, interests, merits and preferences that cause conflicts. The search for solutions is complicated due to interacting political, social, ecologic, economic and technical aspects. The concepts &apos;&apos;wicked problems&apos;&apos; and &apos;'multi-level-governance'&apos; are promising approaches to solve the complicated situation.

    Spontaneously, we do associate &apos;&apos;green medicine&apos;&apos; with terms like naturopathy, natural healing substances, herbal active agents, homeopathy, healthy food, preventive medicine and similar things, and finally we think of ecology. This is the focus of the following article. First of all, the following question arises: Are there any environment-friendly and cost-saving alternatives to the present medicine? There is an increasing number of environment-caused diseases. Therefore, a medicine not coping with the environment is not credible. In today&apos;s medicine, for example, there are too many persistent detergents, water-polluting disinfectants, and many disposable materials. Too much water ist consumed, whereas the use of renewable energies is only limited. And too little natural healing methods are applied in diagnostics and therapy. Presently, in Germany, 16,7 million in-patients are treated in Germany, 1,16 million out-patients have surgeries in 2166 hospitals by ca. 1,1 million medical staff. All this work needs energy and materials which bring various risks to environment and the patients. During the last two decades, however, many efforts were made in the field of environment protection in medicine. There is hardly a hospital left which has not taken measures of protecting the environment. In the branch-specific quality management system KTQ (=cooperation for transparency and quality in the health system). environment protection measures are interrogated and systematically assessed.

  18. &apos;&apos;Measuring the Costs of Climate Change Policies&apos;&apos;

    Studies of the costs of climate change policies have utilized a variety of measures or metrics for summarizing costs. The leading economic models have utilized GNP, GDP, the &apos;&apos;area under a marginal cost curve,&apos;&apos; the discounted present value of consumption, and a welfare measure taken directly from the utility function of the model&apos;s representative agent (the &apos;&apos;Equivalent Variation&apos;&apos;). Even when calculated using a single model, these metrics do not necessarily give similar magnitudes of costs or even rank policies consistently. This paper discusses in non-technical terms the economic concepts lying behind each concept, the theoretical basis for expecting each measure to provide a consistent ranking of policies, and the reasons why different measures provide different rankings. It identifies a method of calculating the &apos;&apos;Equivalent Variation&apos;&apos; as theoretically superior to the other cost metrics in ranking policies. When regulators put forward new economic or regulatory policies, there is a need to compare the costs and benefits of these new policies to existing policies and other alternatives to determine which policy is most cost-effective. For command and control policies, it is quite difficult to compute costs, but for more market-based policies, economists have had a great deal of success employing general equilibrium models to assess a policy&apos;s costs. Not all cost measures, however, arrive at the same ranking. Furthermore, cost measures can produce contradictory results for a specific policy. These problems make it difficult for a policy-maker to determine the best policy. For a cost measures to be of value, one would like to be confident of two things. First one wants to be sure whether the policy is a winner or loser. Second, one wants to be confident that a measure produces the correct policy ranking. That is, one wants to have confidence in a policy measure&apos;s ability to correctly rank

    The effect of prolonged retention of radioactive products (fission fragments) following the &apos;'Starfish'&apos; thermonuclear explosion at F-region altitudes of the ionosphere of lower and middle latitudes discovered on the Kosmos 3, Kosmos 5, and Kosmos 6 satellites is analyzed from the point of view of concepts concerning ion transport processes in the equatorial ionosphere. A qualitative explanation for this phenomenon based on the &apos;&apos;fountain effect&apos;&apos; in the equatorial ionosphere is proposed which is in satisfactory agreement with experiment.

    There exist dark-energy models that predict the occurrence of a &apos;&apos;little rip&apos;&apos;. At the point of a little rip the Hubble rate and its cosmic time derivative approach infinity, which is quite similar to the big rip singularity except that the former happens at infinite future and the latter at a finite cosmic time; both events happen in the future and at high energies. In the case of the big rip, a combination of ultra-violet and infra-red effects can smooth its doomsday. We therefore wonder if the little rip can also be smoothed in a similar way. We address the ultra-violet and infra-red effects in general relativity through a brane-world model with a Gauss-Bonnet term in the bulk and an induced gravity term on the brane. We find that the little rip is transformed in this case into a sudden singularity, or a &apos;&apos;big brake&apos;&apos;. Even though the big brake is smoother than the little rip in that the Hubble rate is finite at the event, the trade-off is that it takes place sooner, at a finite cosmic time. In our estimate, the big brake would happen at roughly 1300 Gyr. (orig.)

    International Nuclear Information System (INIS)

    High-energy radiography is used traditionally for the detection of defects in the thick-walled, bulky components. It is also used for testing the integrity of components for civil and security related applications (containers). The combination of high-energy emitters with digital detector arrays or line cameras allows test procedures in a shorter time compared to film or higher contrast sensitivity. The high-energy X-ray laboratory HEXYLab BAM is a joint laboratory in which future users, manufacturers and scientists can initiate and develop joint development projects. The new universal manipulation system HEXYTech forms the engineering and technical base for the most diverse requirements in HEXYLab (High Energy X-raY Lab.). With a total of 13 rotary and linear axes the diverse trajectories for tube, object and detector can be programmed. So large objects with complex geometries can be examined. 2D and 3D images can be measured by simple radiography, and laminography and computed tomography. The general rules for the application of high energy radiography with digital detectors (imaging plates, Digital detector arrays) were determined within the framework of the European project &apos;'HEDRad'&apos; (High Energy Digital Radiography) and included in the standard DIN EN ISO 17636-2. This article gives an overview of the testing technology and presents the possible applications on the basis of images and experiments. (PowerPoint slides).

  5. What do we mean by the word &apos;'Shock'&apos;?

    International Nuclear Information System (INIS)

    From one vantage point, a shock is a continuous but drastic change in state variables that occurs over very small time and length scales. These scales and associated changes in state variables can be measured experimentally. From another vantage point, a shock is a mathematical singularity consisting of instantaneous changes in state variables. This more mathematical view gives rise to analytical solutions to idealized problems. And from a third vantage point, a shock is a structure in a hydrocode prediction. Its width depends on the simulation&apos;s grid resolution and artificial viscosity. These three vantage points can be in conflict when ideas from the associated fields are combined, and yet combining them is an important goal of an integrated modeling program. This presentation explores an example of how models for real materials in the presence of real shocks react to a hydrocode&apos;s numerical shocks of finite width. The presentation will include an introduction to plasticity for the novice, an historical view of plasticity algorithms, a demonstration of how pursuing the meaning of &apos;'shock'&apos; has resulted in hydrocode improvements, and will conclude by answering some of the questions that arise from that pursuit. After the technical part of the presentation, a few slides advertising LANL&apos;s Computational Physics Student Summer Workshop will be shown.

    A very small potential exists in the Savannah River Site (SRS) separations operations for an uncontrolled reaction between tri-n-butyl phosphate (TBP) and nitric acid that could result in unacceptable damage to separations facilities and a significant release of radioactive materials. The recent &apos;&apos;red oil&apos;&apos; (TBP and nitric acid) accident in Tomsk, Russia, resulted in considerable damage and radioactive release. Explosions have also occurred at SRS during the early years of operations. While the SRS separations facilities have operated without incident for many years, it is prudent to revisit the SRS defense-in-depth approach to preventing such an accident and to upgrade preventive procedures and hardware as appropriate.

    &apos;&apos;Water fountains&apos;&apos; (WFs) are evolved objects showing high-velocity, collimated jets traced by water maser emission. Most of them are in the post-asymptotic giant branch (post-AGB) and they may represent one of the first manifestations of collimated mass loss in evolved stars. We present water maser, carbon monoxide, and mid-infrared spectroscopic data (obtained with the Australia Telescope Compact Array, Herschel Space Observatory, and the Very Large Telescope, respectively) toward IRAS 15103–5754, a possible planetary nebula (PN) with WF characteristics. Carbon monoxide observations show that IRAS 15103–5754 is an evolved object, while the mid-IR spectrum displays unambiguous [Ne II] emission, indicating that photoionization has started and thus, its nature as a PN is confirmed. Water maser spectra show several components spreading over a large velocity range (≅ 75 km s{sup –1}) and tracing a collimated jet. This indicates that the object is a WF, the first WF known that has already entered the PN phase. However, the spatial and kinematical distribution of the maser emission in this object are significantly different from those in other WFs. Moreover, the velocity distribution of the maser emission shows a &apos;'Hubble-like'&apos; flow (higher velocities at larger distances from the central star), consistent with a short-lived, explosive mass-loss event. This velocity pattern is not seen in other WFs (which are presumably in earlier evolutionary stages). We therefore suggest that we are witnessing a fundamental change of mass-loss processes in WFs, with water masers being pumped by steady jets in post-AGB stars, but tracing explosive/ballistic events as the object enters the PN phase.

    This paper presents the results obtained in the characterization of different pyrolysis oils, five oils produced by carbonization and one by flash pyrolysis. Chemical and physical properties such as density, viscosity, elemental composition, char content, water content, solubility and heating value were first determined, then an in-depth chemical characterization was carried out by liquid-liquid fractionation. A diagram indicating the separation procedure, providing four fractions (acids, bases, polars and hydrocarbons), is presented. Polar molecules which were retained in the aqueous layer (&apos;aqueous&apos; fraction) are recuperated. Each fraction wassubsequently analysed by gas chromatography-mass spectrometry (g.c.-m.s.) and Fourier transform infrared spectroscopy (FT-i.r.). The acidic fraction was the most abundant and contained essentially phenolic structures. However, phenols were differently substituted in the two types of oils; alkyl and methoxy groups in the carbonization oils; methoxy, acidic, aldehydic and ketonic functions in the flash pyrolysis oil. The other fractions present a similar composition for all oils. The basic fraction was always very small; some aromatic N-containing compounds were identified. The &apos;polar&apos; neutral fraction was also small and its characterization was very difficult. The hydrocarbon fraction, especially, was constituted of aromatics and cyclics, and some aliphatics were also identified. The &apos;aqueous&apos; fraction contained mainly carboxylic esters, alcohols and ethers. 31 refs., 4 figs., 5 tabs.

    The design and creation of molecular nanostructures with specific mechanical functions is one of the fundamental issues in nanotechnology. In this context, wheels are an interesting component for the molecular motion, because they are expected to alter the diffusion properties on surfaces, for instance by allowing only directed motion. In the presented work, we show the absorption of functional molecules studied by scanning tunneling microscopy under ultrahigh vacuum at low temperatures of about 7 K. The molecules consist of a phenyl chain, equipped with carborane side groups that represent the molecular &apos;'wheels'&apos;. Additionally, bromine atoms are attached to the terminal groups of the molecules, which should allow the covalent connection of individual molecules, according to our recently presented oen-surface-synthesis&apos;&apos; method. The high mobility of the molecules during deposition, at room temperature, enables them to form molecular nanostructures. Characteristic appearances of the molecules, due to different molecular configurations, are found. Furthermore, lateral manipulation was used to displace molecules and to probe their intermolecular interactions.

    Full Text Available Direct seeding is one of the most promising methods in restoration ecology, but low field seedling emergence from pioneer tree seeds still reduces its large scale applicability. The aim of this research was to evaluate seed priming for the pioneer tree species Guazuma ulmifolia. Priming treatments were selected based on seed hydration curves in water and in PEG 8000 solution. Seeds were primed in water for 16 h and in Polyethylene glycol - PEG 8000 (-0.8 MPa for 56 and 88 h at 20ºC to reach approximately 30% water content. Half of the seed sample of each treatment was dried back to the initial moisture content (7.2%; both dried and non-dried primed seeds as well as the unprimed seeds (control were tested for germination (percentage and rate and vigor (electrical conductivity of seed leachates. Seedling emergence percentage and rate were evaluated under greenhouse conditions, while seedling length and uniformity of seedling development were estimated using the automated image analysis software SVIS®. Primed seeds showed the highest physiological potential, which was mainly demonstrated by image analysis. Fresh or dried primed seeds in water for 16 h and in PEG (-0.8 MPa for 56 h, and fresh primed seeds in PEG for 88 h, improved G. ulmifolia germination performance. It is suggested that these treatments were promising to enhance efficiency of stand establishment of this species by direct seeding in restoration ecology programs.A semeadura direta é um dos métodos mais promissores para a restauração ecológica, mas a baixa emergência de plântulas em campo a partir de sementes de árvores pioneiras ainda limita sua aplicabilidade em larga escala.

    There are plans for Swiss pumped hydrostorage systems to absorb large quantities of excess electricity from European wind and solar power generation. Model-based analyses have shown however that &apos;'Europe&apos;s battery&apos;&apos;, as Switzerland would like to see itself, will not be needed until the middle of this century. Even if all extension projects currently in progress should be completed, Switzerland will not have sufficient pump capacity or import capacity to absorb large amounts of excess electricity. Furthermore, the primary means of making storage capacity available for import electricity would be to reduce reservoir power plant capacity. In view of all this Switzerland&apos;s hopes for a role as a major European electricity storage provider appear somewhat exaggerated even in the long-term perspective.

    The pressure dependence of the intervalence-transfer (IT) electronic absorption band has been determined for the mixed-valence biferrocenium and 1&apos;,1&apos;'&apos;-diethylbiferrocenium cations intercalated into a clay and for the following eight microcrystalline compounds: biferrocenium triiodide (1); biferrocenium hexafluorophosphate (2); 1&apos;,1&apos;'&apos;-diiodobiferrocenium triiodide (3); 1&apos;,1&apos;'&apos;-diiodobiferrocenium dibromoiodate (4); 1&apos;,1&apos;'&apos;-dibromobiferrocenium triiodide (5); 1&apos;,1&apos;'&apos;-dichlorobiferrocenium triiodide hemiiodine (6); 1&apos;,1&apos;'&apos;-diethylbiferrocenium triiodide (7); 1&apos;,1&apos;'&apos;-di-n-butylbiferrocenium triiodide (8). Basically three different types of pressure dependencies of the energy of the IT band are seen. Compounds 3-5, which have a solid-state packing arrangement consisting of alternating stacks of cations and anions, exhibit one type of behavior. For these three compounds the IT band shifts blue initially with pressure, and above approx. 80 kbar there is the onset of a rather abrupt reversal where the IT band shifts red with increasing pressure.

    To determine the potential of novel gradient echo parameters, &apos;&apos;Black Bone&apos;&apos; MRI as an alternative to CT in the identification of normal and prematurely fused cranial sutures both in 2D and 3D imaging. Thirteen children with a clinical diagnosis of craniosynostosis underwent &apos;&apos;Black Bone&apos;&apos; MRI in addition to routine cranial CT. &apos;&apos;Black Bone&apos;&apos; datasets were compared to CT and clinical findings. &apos;&apos;Black Bone&apos;&apos; imaging was subsequently used to develop 3D reformats of the craniofacial skeleton to enhance further visualisation of the cranial sutures. Patent cranial sutures were consistently identified on &apos;&apos;Black Bone&apos;&apos; MRI as areas of increased signal intensity. In children with craniosynostosis the affected suture was absent, whilst the remaining patent sutures could be visualised, consistent with CT and clinical findings. Segmentation of the &apos;&apos;Black Bone&apos;&apos; MRI datasets was successful with both threshold and volume rendering techniques. The cranial sutures, where patent, could be visualised throughout their path. Patent cranial sutures appear as areas of increased signal intensity on &apos;&apos;Black Bone&apos;&apos; MRI distinct from the cranial bone, demonstrating considerable clinical potential as a non-ionising alternative to CT in the diagnosis of craniosynostosis.

    Urinary metabolites were tested in 41 shoe-factory workers exposed to a mixture of 10 solvents among which &apos;&apos;commercial hexane&apos;&apos; was the prevailing component. Cyclohexanol, 2-methyl-2-pentanol, 3-methyl-2-pentanol, and trichloroethanol were determined in connection with exposure to cyclohexane, 2-methylpentane, 3-methylpentane, and trichloroethylene, respectively. 2-Hexanol, 2,5-hexanedione, 2,5-dimethylfuran, and gamma-valerolactone were all determined in connection with n-hexane exposure only. 2,5-Hexanedione was the principal n-hexane metabolite found in the workers&apos; urine. This finding of the experimentally proven neurotoxin 2,5-hexanedione in the urine of shoe-factory workers exposed to &apos;&apos;commercial hexane&apos;&apos; is consistent with the idea that this compound is responsible for the development of neuropathy in this group of individuals.

    The effects of irradiation dose and refrigerated storage conditions on &apos;Nagpur&apos; mandarin (Citrus reticulata Blanco), &apos;Mosambi&apos; sweet orange (Citrus sinensis Osbeck) and &apos;Kagzi&apos; acid lime (Citrus aurantifolia Swingle) were investigated. Mature fruits of these three species were treated with 0, 0.25, 0.5, 1 and 1.5 kGy radiation. &apos;Nagpur&apos; mandarin and &apos;Mosambi&apos; sweet oranges were stored at 6-7 deg. C and 90-95% r.h. for 75 and 90 days, respectively, while &apos;Kagzi&apos; acid limes were stored at 8{+-}1 deg. C and 90-95% r.h. for 90 days. Physico-chemical parameters, sensory attributes and respiration rate were measured besides losses and disorders. In &apos;Nagpur&apos; mandarin, radiation dose upto 1.5 kGy did not cause any rind disorder. Radiation treatments did not reduce the extent of decay. Penicillium rot was delayed in fruit treated with 1.5 kGy, while it appeared early in 0 kGy. Irradiation doses were ineffective to control rots due to Botryodiplodia theobromae and Alternaria citri. Doses upto 1.5 kGy did not cause any significant effect on fruit firmness and juice content; however, total soluble solids increased, while titratable acidity and vitamin &apos;C&apos; content decreased. Texture and flavour scores as recorded after a week, were not affected by irradiation except in 1.5 kGy. In &apos;Mosambi&apos; sweet orange, radiation treatments caused peel disorder in the form of brown sunken areas after 90 days and reduced fruit firmness, acidity and vitamin C content. The TSS content was higher in treated fruit. Flavour and texture were not affected by the doses of irradiation used. In treated acid limes (mature yellow), weight loss and decay were higher than untreated fruit (0 kGy) although difference was non-significant. Juice, TSS, titratable acidity and vitamin C contents were significantly less in treated fruit than in 0 kGy. Texture and flavour scores were also less in treated fruit than in 0 kGy. The

    The contra-rotating propeller (CRP) system was developed by IHI aiming at the energy saving for large size ship and installed to JUNO&apos;&apos;, a 37,000 DWT bulk carrier in January 1989. The voyage history after commissioning concerning energy-saving effect, performance after repair of ice-damage, present situation and future prospects was reported. It was revealed that the CRP-ship was superior to ordinary ships equipped with conventional propeller not only in propelling function but also in controllability of ship and such properties as propeller cavitation, pressure fluctuation, and noise. The energy saving was 15 % in comparison with conventional propeller. JUNO had an accident in St. Lawrence Bay in February 1990 during her trial voyage. The blade-tips were damaged by ice floes. However, no abnormality was observed after repairing. The voyage for one year and half proved the complete success in practical utilization of CRP system. Further improvement of technology together with the scale-up will make it possible to apply the CRP system to larger power ships such as VLCC{prime}s. The development of cleaning technology of exhaust gas from the engine has to be considered because the ship uses high sulfur content fuel oil. 15 figs.

    This paper investigates a method of reconstructing images from energy-resolved CT data with negligible beam-hardening artifacts and improved contrast-to-nosie ratio (CNR) compared to conventional energy-weighting methods. Conceptually, the investigated method first reconstructs separate images from each energy bin. The final image is a linear combination of the energy-bin images, with the weights chosen to maximize the CNR in the final image. The optimal weight of a particular energy-bin image is derived to be proportional to the contrast-to-noise-variance ratio in that image. The investigated weighting method is referred to as &apos;'image-based'&apos; weighting, although, as will be described, the weights can be calculated and the energy-bin data combined prior to reconstruction. The performance of optimal image-based energy weighting with respect to CNR and beam-hardening artifacts was investigated through simulations and compared to that of energy integrating, photon counting, and previously studied optimal &apos;'projection-based'&apos; energy weighting. Two acquisitions were simulated: dedicated breast CT and a conventional thorax scan. The energy-resolving detector was simulated with five energy bins. Four methods of estimating the optimal weights were investigated, including task-specific and task-independent methods and methods that require a single reconstruction versus multiple reconstructions. Results demonstrated that optimal image-based weighting improved the CNR compared to energy-integrating weighting by factors of 1.15-1.6 depending on the task. Compared to photon-counting weighting, the CNR improvement ranged from 1.0 to 1.3. The CNR improvement factors were comparable to those of projection-based optimal energy weighting. The beam-hardening cupping artifact increased from 5.2% for energy-integrating weighting to 12.8% for optimal projection-based weighting, while optimal image-based weighting reduced the cupping to 0

    Four wheels, two seats, one steering wheel: What does it require more for a small, electrically powered city car? Nothing, says the manufacturer. Two side windows, that is our opinion. With a maximum speed of 80 kilometers per hour and a range of 100 kilometers, the vehicle is certainly ideal for many applications over short distances in the city. PHOTON now uses the &apos;'Twizy'&apos; for almost a year, and gained consistently good experiences.

    We have discovered that microorganisms produce and emit the hydrocarbon isoprene (2-methyl-1,3-butadiene), and have suggested that if isoprene-producing enzymes and their genes can be harnessed, useful hydrocarbon-producing systems might be constructed. The main goal of the proposed work is to establish the biochemical mechanism and regulation of isoprene formation in the bacterial system, Bacillus subtilis. Specific objectives of the proposed work are the following: (A) to characterize the physiological regulation of isoprene formation in B. subtilis; (B) to characterize mutations in B. subtilis 168 that suppress isoprene formation, clone these genes, and determine how isoprene and isoprenoid carbon flow are regulated; and (C) to test &apos;'overflow'&apos; and &apos;'signaling'&apos; models for Bacillus isoprene formation. We are also pursuing the isolation and cloning of B. subtilis isoprene synthase, which we believe may be a regulatory enzyme.

    The unique beam-delivery technique of Tomotherapy machines (Accuray Inc., Sunnyvale, Calif.) necessitates tailored quality assurance. This requirement also applies to external dose intercomparisons. Therefore, the aim of the 2014 SSRMP (Swiss Society of Radiobiology and Medical Physics) dosimetry intercomparison was to compare two set-ups with different phantoms. A small cylindrical Perspex phantom, which is similar to the IROC phantom (Imaging and Radiation Oncology Core, Houston, Tex.), and the &apos;'cheese'&apos; phantom, which is provided by the Tomotherapy manufacturer to all institutions, were used. The standard calibration plans for the TomoHelical and TomoDirect irradiation techniques were applied. These plans are routinely used for dose output calibration in Tomotherapy institutions. We tested 20 Tomotherapy machines in Germany and Switzerland. The ratio of the measured (D{sub m}) to the calculated (D{sub c}) dose was assessed for both phantoms and irradiation techniques. The D{sub m}/D{sub c} distributions were determined to compare the suitability of the measurement set-ups investigated. The standard deviations of the TLD-measured (thermoluminescent dosimetry) D{sub m}/D{sub c} ratios for the &apos;'cheese'&apos; phantom were 1.9 % for the TomoHelical (19 measurements) and 1.2 % (11 measurements) for the TomoDirect irradiation techniques. The corresponding ratios for the Perspex phantom were 2.8 % (18 measurements) and 1.8 % (11 measurements). Compared with the Perspex phantom-based set-up, the &apos;'cheese'&apos; phantom-based set-up without individual planning was demonstrated to be more suitable for Tomotherapy dose checks. Future SSRMP dosimetry intercomparisons for Tomotherapy machines will therefore be based on the &apos;'cheese'&apos; phantom set-up. (orig.)

    This decision from the French authority of nuclear safety (ASN) aims at validating the new versions of the guidebook for the elaboration of &apos;waste studies&apos; for nuclear facilities and of the specifications for the elaboration of &apos;waste statuses&apos; for nuclear facilities. This paper includes two documents. The first one is a guidebook devoted to nuclear facility operators which fixes the rules of production of waste studies according to the articles 20 to 26 of the inter-ministry by-law from December 31, 1999 (waste zoning conditions and ASN&apos;s control modalities). The second document concerns the specifications for the establishment of annual waste statuses according to article 27 of the inter-ministry by-law from December 31, 1999 (rational management of nuclear wastes).

    The spectral density of fluctuations in the audio power of many musical selections and of English speech varies approximately as 1/f (f is the frequency) down to a frequency of 5 x 10/sup -4/ Hz. This result implies that the audio-power fluctuations are correlated over all times in the same manner as &apos;&apos;1/f noise&apos;&apos; in electronic components. The frequency fluctuations of music also have a 1/f spectral density at frequencies down to the inverse of the length of the piece of music. The frequency fluctuations of English speech have a quite different behavior, with a single characteristic time of about 0.1 s, the average length of a syllable. The observations on music suggest that 1/f noise is a good choice for stochastic composition. Compositions in which the frequency and duration of each note were determined by 1/f noise sources sounded pleasing. Those generated by white-noise sources sounded too random, while those generated by 1/f/sup 2/ noise sounded too correlated.

    In high-energy astrophysics, it is common practice to account for the background overlaid with counts from the source of interest with the help of auxiliary measurements carried out by pointing off-source. In this &apos;'on/off'&apos; measurement, one knows the number of photons detected while pointing toward the source, the number of photons collected while pointing away from the source, and how to estimate the background counts in the source region from the flux observed in the auxiliary measurements. For very faint sources, the number of photons detected is so low that the approximations that hold asymptotically are not valid. On the other hand, an analytical solution exists for the Bayesian statistical inference, which is valid at low and high counts. Here we illustrate the objective Bayesian solution based on the reference posterior and compare the result with the approach very recently proposed by Knoetig, and discuss its most delicate points. In addition, we propose to compute the significance of the excess with respect to the background-only expectation with a method that is able to account for any uncertainty on the background and is valid for any photon count. This method is compared to the widely used significance formula by Li and Ma, which is based on asymptotic properties.

  17. Direct detection of light &apos;'Ge-phobic'&apos; exothermic dark matter

    International Nuclear Information System (INIS)

    We present comparisons of direct dark matter (DM) detection data for light WIMPs with exothermic scattering with nuclei (exoDM), both assuming the Standard Halo Model (SHM) and in a halo model–independent manner. Exothermic interactions favor light targets, thus reducing the importance of upper limits derived from xenon targets, the most restrictive of which is at present the LUX limit. In our SHM analysis the CDMS-II-Si and CoGeNT regions become allowed by these bounds, however the recent SuperCDMS limit rejects both regions for exoDM with isospin-conserving couplings. An isospin-violating coupling of the exoDM, in particular one with a neutron to proton coupling ratio of -0.8 (which we call &apos;'Ge-phobic'&apos;), maximally reduces the DM coupling to germanium and allows the CDMS-II-Si region to become compatible with all bounds. This is also clearly shown in our halo-independent analysis

    Using the exact Lemaitre-Bondi-Tolman solution with a non-vanishing cosmological constant {Lambda}, we investigate how the presence of a local spherically symmetric inhomogeneity can affect apparent cosmological observables, such as the deceleration parameter or the effective equation of state of dark energy (DE), derived from the luminosity distance under the assumption that the real space-time is exactly homogeneous and isotropic. The presence of a local underdensity is found to produce apparent phantom behavior of DE, while a locally overdense region leads to apparent quintessence behavior. We consider relatively small large scale inhomogeneities which today are not linear and could be seeded by primordial curvature perturbations compatible with CMB bounds. Our study shows how observations in an inhomogeneous {Lambda}CDM universe with initial conditions compatible with the inflationary beginning, if interpreted under the wrong assumption of homogeneity, can lead to the wrong conclusion about the presence of &apos;'fake'&apos; evolving dark energy instead of {Lambda}.

    The &apos;'forest'&apos; of absorption lines observed in the spectrum of distant quasars is interpreted in light of the adiabatic (pancake) theory for the origin and evolution of structure in the universe. The hidden mass might reside in neutrino-like particles (perhaps unstable) having a rest mass of about 60--100 eV. Opportunities for testing the hypothesis observationally are discussed.

    Small Angle Neutron Scattering experiments were carried out on liquid crystalline &apos;&apos;side-on fixed&apos;&apos; polyacrylates: we observe that the polymer backbone adopts a prolate conformation in the nematic phase. Such anisotropy of the global backbone is larger for smaller spacer lenght. In every case we measure at low temperatures a large chain extension as previously described in polysiloxanes. (orig.).

    Probing the matter in order to check its elementary constituents, that is the goal of the particle physic. In this field, the experiments consist in colliding highly energetic particle beams and observing the new born particles. These observations are based on big particle detectors whose running is dependant on the precise knowledge of their geometry (position of the detection chambers). To achieve this, the detectors are equipped with alignment sensors, which have to be calibrated before. This document describes the study and the making of a calibration bench for the &apos;Praxial&apos; (PRoximity AXIAL) type sensors, and other works related to these sensors. In a first part, we determine and apply a method to set the tools used to fix the sensor stands on the detection chambers. These settings are made with the use of a tridimensional measuring machine. Then, we study the stands themselves. These investigations concern mechanics: positioning quality of the sensors in their stands, bending of the supports due to the tightening. In this part too, the studies are in the field of dimensional metrology. After this, the works are reoriented toward the bench, with the choice of the displacement sensors among two different technologies: optical, with the Rasnik system, and mechanical, with linear probes as LVDT (Linear Variable Differential Transformer). Following the discovery of an ambiguity on the Rasnik system, we go on the tests to understand its behaviour. We introduce the theory of the alignment sensors calibration, which is based on a minimization calculation. The computer programs are explained in a chapter, and in an other, the implementation of the quality assurance procedures. An other part describes the mechanical studies and the problems they cause. Because of a delay onset of the project, we make a model of the bench. This dummy allows us to test every single function of the final bench. With this device, we record manually the first calibration data and

    &apos;&apos;What if electronics devices are printed using an inkjet printer even at home?&apos;&apos; &apos;&apos;What if those devices no longer need a battery?&apos;&apos; I will introduce two enabling technologies for the Internet of Things concept. 1. Instant Inkjet Circuits: A low cost, fast and accessible technology to support the rapid prototyping of electronic devices. We demonstrated that &apos;'sintering-free'&apos; silver nano particle ink with a commodity inkjet printer can be used to fabricate printed circuit board and high-frequency applications such as antennas and sensors. The technology is now commercialized by AgIC, Inc. 2. Wireless Power: Although large amounts of data can be exchanged over a wireless communication link, mobile devices are still tethered by power cables. We are trying to solve this problem by two different approaches: energy harvesting. A simple circuitry comprised of diodes and capacitor can convert ambient radio signals into DC current. Our research revealed the signals from TV tower located 6.5km apart could be used to feed 100 microwatts to power microcontrollers

    To most audiences, deterrence has been interconnected with nuclear weapons whose purpose had been to deter a Soviet attack. But, the Soviet Union has been gone for almost a decade. President George W. Bush has stated that Russia is not an enemy of the US and the numbers of nuclear weapons can be dramatically reduced. It is important to note that deterrence has always transcended nuclear weapons. The US&apos; first line of deterrence has been its formidable conventional warfare capability, designed to prevent conflict and win wars if necessary. The role of nuclear weapons has been to deter the,use of nuclear weapons and other weapons of mass destruction against U.S. interests during the conduct of conventional warfare and to ensure our ability to inflict massive destruction on any who would use nuclear weapons, or other weapons of mass destruction, against us. With regard to the Soviet Union, the threat of the use of nuclear weapons was a critical component of our deterrent to prevent massive Soviet conventional attack against our allies in Europe. However, the events of September 11, 2001 make clear that we have not convinced all who seek to harm us that we will be able to respond in a manner to make them wish they had not even tried. The September 11 attacks, as well as other past conflicts, do not mean that deterrence has failed-it remains effective against the threats for which it was designed. We have known there are other threats for which we did not have a credible deterrent. The challenge is to sustain deterrence against the classic threats as they evolve in technical sophistication while remaining alert to the need to evaluate continuously our ability to deter previously unforeseen challenges. How then should we be looking at deterrence as we consider fifteen or so years in the future, say to about 2015? What will be the role of nuclear weapons and other instruments of mass destruction in the future? What should the US be doing to prepare for the future? In

    Purpose: To prospectively assess the spectrum of brain CT findings in psychiatric patients and to determine the number of patients that had an underlying cause for the symptoms. Patients and methods: Over a period of six months, 142 patients (78 males, 64 females; median age 61 [18-91] years) were referred for CT brain scans. Their scans were reviewed, along with the clinical information that was provided in the request form. All the hard copies were reviewed to assess areas of ischaemia, infarction, atrophy, tumours, and haematomas. The majority of requests were to exclude vascular event or space-occupying lesions. Clinical indications included mood disorders (depression, mania), schizophrenic disorders, dementia, personality and behavioural disorders. Results: 31 (22%) were normal. 111 (78%) had varying degrees of ischaemia, infarction and cerebral/cerebellar atrophy. 7 (4.9%) had space-occupying lesions which included two gliomas and five meningiomas. There were two chronic subdural haematomas and one arteriovenous malformation. Conclusion: 1. In our series, pathologic findings in &apos;routine&apos; brain CT&apos;s were encountered in 78%. 2. The incidence of brain tumours was 4.9%, compared with 0.00005% of the general population. 3. CT scanning in psychiatric patients is cost-effective and especially indicated when there is an atypical presentation, or inadequate response to standard treatment. (orig.)

    &apos;Dose-painting&apos; radiotherapy allows for a heterogeneous delivery of radiation within the tumour volume by targeting radioresistant areas defined by functional imaging. Within gross tumour volume, it is possible to define one or more target volumes based on biology (biological target volume [BTV]) and to apply a strategy of intensity modulated radiation therapy (IMRT) that will deliver a higher dose to these regions. In this review of the literature, we will highlight the biological elements responsible for radioresistance, and how to image them, then we will detail the radiotherapy techniques necessary for this approach, before presenting clinical results in various situations (head and neck tumours, prostate, brain tumours, etc.). Despite many difficulties that make dose-painting IMRT unusable in routine nowadays, biology-guided radiation therapy represents one of the major pathways of development of radiotherapy in the coming years.

    The involvement of apolipoproteins, such as the ApoE4 isoform, in Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA) highlights the fact that certain lipid carriers may participate in soluble β-amyloid (Aβ) transport. Our general aim was to characterize the soluble levels of the apolipoproteins apoE, apoA1 and apoJ/clusterin and their genotype status in patients with CAA. We analyzed the genotypes frequency of APOA1 (rs5069, rs670), CLU (rs11136000, rs1532278, rs7012010, rs9331888) and APOE (rs429358, rs7412) in a cohort of patients with CAA-associated intracerebral hemorrhage (ICH) (n = 59) and compared the results with those from hypertension-associated ICH (n = 42), AD patients (n = 73) and controls (n = 88). In a subgroup of patients, we also determined the plasma concentrations of apoE, apoA1 and apoJ/clusterin. We found increased plasma apoJ/clusterin levels in CAA patients compared to AD patients or controls after adjusting for sex and age (CAA vs. controls, p = 0.033; CAA vs. AD, p = 0.013). ApoA1 levels were not altered between groups, although a strong correlation was observed between plasma Aβ(1-40) and apoA1 among CAA patients (r = 0.583, p = 0.007). Regarding plasma apoE concentration, a robust association between circulating levels and genotype status was confirmed (p < 0.001). Whereas the APOE4 frequency was higher in AD (p < 0.001) and CAA (p = 0.013), the APOA1 and CLU genotypes were not different among groups. In the CAA cohort, the risk-linked CLU variant (C) rs11136000 was associated with white matter hyperintensities (p = 0.045) and the presence of lobar microbleeds (p = 0.023) on MRI. In summary, our findings suggest that apoA1 may act as a physiological transporter of Aβ(1-40) and that apoJ/clusterin appears to be a chaperone related to distinctive lesions in CAA brains.

    The &apos;&apos;cartilage black line sign&apos;&apos; is a recently described T2 dark cartilage lesion that we have identified appearing as a cleft in the trochlear trough. The purpose of our study was to define the MR imaging characteristics of a trochlear cleft, determine its incidence, and correlate the MR findings with arthroscopy. A total of 1,300 consecutive MR examinations of the knee were retrospectively reviewed by consensus of two fellowship-trained musculoskeletal radiologists. The MR imaging characteristics and location of a trochlear cleft were determined. Imaging results were compared to arthroscopy when available. Patient age and gender were compared to 25 randomly selected control patients without trochlear clefts. A total of 25 (1.9%) individuals (11 females and 14 males; age range 19-45 years; mean age 28 years) were diagnosed with a trochlear cleft. The control group consisted of 11 females and 14 males; age range 19-83 years; mean age 46 years. Mean cleft length was 7 mm (range 6-12 mm); cleft location was consistently in the lower trochlear trough. No full-thickness cartilage defects were identified in the eight individuals in whom arthroscopic correlation was available. A grade 2 cartilage lesion was identified in a single individual; another progressed from grade 0 to a full-thickness trochlear lesion over an 8-month interval. Eight individuals were athletes. No significant difference in gender was noted between the two groups, however, the study group was significantly younger p < 0.0001. A trochlear cleft is a rare finding in young active individuals. It most likely indicates an incomplete cartilage fissure which may rarely progress to a full-thickness defect. (orig.)

    This is the final report for a one year close out extension of our basic research program that was established at the University of Chicago more than sixteen years ago to explore and develop the optical sub-discipline that has come to be known as &apos;&apos;nonimaging optics&apos;&apos;. This program has been extremely fruitful, having both broadened the range of formalism available for workers in this field and led to the discovery of many new families of optical devices. These devices and techniques have applications wherever the efficient transport and transformation of light distributions are important, in particular in illumination, fiber optics, collection and concentration of sunlight, and the detection of faint light signals in physics and astrophysics. Over the past thirty years, Nonimaging Optics (Welford and Winston, 1989) has brought a fresh approach to the analysis of many problems in classical macro-scale optics. Through the application of phase-space concepts, statistical methods, thermodynamic arguments, etc., many previously established performance limits were able to be broken and many technical surprises with exciting practical applications were discovered. The most recent three-year phase of our long-term continuing program ended in late 2002 and emphasized extending our work in geometrical optics and expanding it to include some interesting questions in physical optics as well as in the new field of statistical optics. This report presents a survey of the basic history and concepts of nonimaging optics and reviews highlights and significant accomplishments over the past fifteen years. This is followed by a more detailed summary of recent research directions and accomplishments during the last three years. This most recent phase was marked by the broadening in scope to include a separate project involving a collaboration with an industrial partner, Science Applications International Corporation (SAIC). This effort was proposed and approved in

    To examine the anatomic MRI characteristics of the adductor magnus mini hamstring (AMMH) and explore its involvement in cases of hamstring avulsion. An IRB-approved retrospective review of patients undergoing &apos;&apos;hamstring protocol&apos;&apos; MRI between March 2009 and June 2014 was performed. Two musculoskeletal radiologists recorded multiple AMMH anatomic characteristics and involvement in cases of hamstring avulsion. Seventy-six AMMHs were analyzed in 66 patients [35 females and 31 males, mean age 49.3 ± 15.2 years (range 17-81)]. Eleven percent of AMMHs were poorly visualized, 51 % visualized, and 37 % well visualized. Seven percent demonstrated round, 73 % ovoid, and 21 % flat/lenticular tendon morphologies. Most (88 %) demonstrated typical origins. Average cross-sectional area (CSA) was 22.4 ± 10.6 mm{sup 2} (range 6-56), diameter was 7.2 ± 2.5 mm (range 2.9-15), medial distance from the semimembranosus tendon was 7.5 ± 2.5 mm (range 3-14), and tendon length was 6.8 ± 3.3 cm (range 1.2-14.1). There was no gender difference in AMMH anatomic measurements or correlation between age and CSA or diameter. Of 17 complete hamstring avulsion cases, the AMMH was intact in 13, partially torn in 3, and completely torn in 1. The AMMH is a constant finding with variable anatomic characteristics. It is visualized or well visualized by MRI in 88 % of cases and is a sizable tendon located in close proximity to the semimembranosus tendon. Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

    This paper develops a theory of &apos;oil&apos;igopoly exploration of an exhaustible resource. Strategic exploration and production are jointly derived in a three period subgame perfect equilibrium. While the &apos;oil&apos;igopoly theory of exploration shares many features with non-strategic models of exploration and production, there is one important difference. The &apos;oil&apos;igopoly theory of exploration predicts that firms who exhaust their proved reserves before they can convert their unproved reserves into proved reserves have an incentive to over-explore, relative to the Nash equilibrium level of exploration. A simple empirical prediction is that firms holding smaller proved reserves should be observed doing more exploration. This prediction is consistent with country-level production and reserve data in the post-World War II era. (author)

    Queensland-based Capricorn Coal Management and SMC Pneumatics (Australia) have developed a new methane drainage system incorporating a pneumatically controlled &apos;automatic shut down system&apos; (ASDS) that, in an emergency situation, automatically terminates the flow of gas at the source with automatic shut-off valves. The air supply unit incorporates two air compressors operating in a rotating cycle to ensure continuous supply with pressure and flow measurement sensors and solenoid valves configured to &apos;fail-to-safety&apos; in the event of power failure. The SMC-Capcoal system has been operating successfully for two years at Capcoal&apos;s Central colliery, Queensland&apos;s first longwall mine. It can shut off methane flows within 90 seconds. 3 photos.

  1. Irradiation as a quarantine treatment of &apos;Carabao&apos; (&apos;Manila Super&apos;) mangoes

    International Nuclear Information System (INIS)

    Researches using gamma radiation for disinfestation of Oriental fruit fly in &apos;Carabao&apos; (&apos;Manila Super&apos;) mangoes were undertaken using the Probit 9 or 99.9968% mortality test. The results showed that the mature larvae of the fruit fly are the most tolerant stage of this insect to irradiation with the eggs as the most sensitive. On treating more than 100,000 mature larvae in mangoes, a minimum dose of 100 Gy was found to prevent emergence of adult fruit flies and maintain quarantine security or a complete elimination of the possibility of introducing this pest into the importing country. Therefore, the use of 100-Gy irradiation as a quarantine treatment against Oriental fruit fly in the mature green Philippine &apos;carabao&apos; mango fruits is recommended

    We investigate the teleportation scheme of two-mode squeezed states proposed by Adhikari et al.[S. Adhikari et al., Phys. Rev. A 77, 012337 (2008)]. It uses four-mode entangled states to teleport two-mode squeezed states. The fidelity between the original two-mode squeezed states and teleported ones is calculated. The maximal fidelity value of Adhikari&apos;s protocol is 0.38, which is incompatible with the fidelity definition with the maximal value 1. In our opinion, one reason is that they calculate the fidelity for multimodes Gaussian states using the fidelity formula for single-mode ones. Another reason is that the covariance matrix of output states should be what is obtained after applying the linear unitary Bogoliubov operations (two cascaded Fourier transformations) on the covariance matrix given in Eq. (12) in their paper. These two reasons result in the incomparable results. In addition, Adhikari&apos;s protocol can be simplified to be easily implemented.

  17. CONSTRAINING THE EVOLUTIONARY FATE OF CENTRAL COMPACT OBJECTS: &apos;'OLD'&apos; RADIO PULSARS IN SUPERNOVA REMNANTS

    International Nuclear Information System (INIS)

    Central compact objects (CCOs) constitute a population of radio-quiet, slowly spinning (≥100 ms) young neutron stars with anomalously high thermal X-ray luminosities. Their spin-down properties imply weak dipole magnetic fields (∼1010-11 G) and characteristic ages much greater than the ages of their host supernova remnants (SNRs). However, CCOs may posses strong &apos;'hidden'&apos; internal magnetic fields that may re-emerge on timescales of ≳10 kyr, with the neutron star possibly activating as a radio pulsar in the process. This suggests that the immediate descendants of CCOs may be masquerading as slowly spinning &apos;'old'&apos; radio pulsars. We present an X-ray survey of all ordinary radio pulsars within 6 kpc that are positionally coincident with Galactic SNRs in order to test the possible connection between the supposedly old but possibly very young pulsars and the SNRs. None of the targets exhibit anomalously high thermal X-ray luminosities, suggesting that they are genuine old ordinary pulsars unrelated to the superposed SNRs. This implies that CCOs are either latent radio pulsars that activate long after their SNRs dissipate or they remain permanently radio-quiet. The true descendants of CCOs remain at large

These variations have been shown to limit the performances of vegetation indices (NDVI and SAVI) in discriminating low vegetation covers. The redness index is used to adjust for this &apos;&apos;soil noise&apos;&apos;. Dala simulated for vegetation densities of 5 to 15% cover showed that the sensitivity of the corrected vegetation indices was significantly improved. Specifically, the &apos;'noise-corrected'&apos; SAVI was able to assess vegetation amounts with an error four times smaller than the uncorrected NDVI. These promising results should lead to a significant improvement in assessing biomass in arid lands from remotely sensed data. (author)

    The total neutron fluence during the life time is expected to be around 10MW·yr/m&apos;&apos;2 which may cause a damage of -100 dpa in materials. To estimate the adaptability of candidate materials in a few years, a 14MeV neutron source with a flux level of 3 - 5 x 10&apos;&apos;1&apos;&apos;8 n/s·m&apos;&apos;2, which is the goal of the IFMIF facility costing more than ¤1000M, is necessitated. The problem in making an intense neutron generator of beam target type is really not on the neutron production rate, but on the huge heat generated in the target, because the fusion power is only one of thousands of beam power exerted on the target. We have a plan to develop neutron generators step by step from a 10&apos;&apos;8 n/s level. The final goal is establishing a 14MeV neutron irradiation facility at 10&apos;&apos;1&apos;&apos;4 intensity level.. Up to the 10&apos;&apos;1&apos;&apos;0 n/s level, there occurs basically no critical thermal problem, because beam power density is in the range of tens W/cm&apos;&apos;2. The neutron generator designed in a sealed-off type because of tritium safety is mainly composed of an ion source, target, reaction chamber, and getter pump.. The major design concepts for the neutron generator with the neutron production rate of 10&apos;&apos;1&apos;&apos;1 n/s range were presented. The specifications of the ion source, target and getter have been determined for attaining the goal of the neutron generation rate.

    Apolipoprotein E4 (apoE4), one of three isoforms of apoE, is the major risk factor for developing late onset Alzheimer's disease. The only differences among these isoforms (apoE2, apoE3, and apoE4) are single amino acid changes. Yet these proteins are functionally very different. One approach to ameliorating the effect of apoE4 with respect to Alzheimer's disease would be to find small molecular weight compounds that affect the behavior of apoE4. Few studies of this approach have been carried out in part because there was no complete structure of any full-length apoE isoform until 2011. Here, we focus on one small molecular weight compound, EZ-482, and explore the effects of its binding to apoE. Using hydrogen-deuterium exchange, we determined that EZ-482 binds to the C-terminal domains of both apoE3 and apoE4. The binding to apoE4, however, is accompanied by a unique N-terminal allosteric effect. Using fluorescence methods, we determined an apparent dissociation constant of approximately 8 μM. Although EZ-482 binds to the C-terminal domain, it blocks heparin binding to the N-terminal domain. The residues of apoE that bind heparin are the same as those involved in apoE binding to LDL and LRP-1 receptors. The methods and the data presented here may serve as a template for future studies using small molecular weight compounds to modulate the behavior of apoE. PMID:27065061

    The presentation outlines and Accompanying Measure with the FP 5 to develop an web based EUropean Sustainable Land and GRoundwater Management Information System information system (EUGRIS). The management of contaminated land and groundwater requires an interdisciplinary approach and a considerable amount of supporting technical information and knowledge. EUGRIS will provide a generally available comprehensive and overarching information and innovation resource, to support both research and practical contaminated land and groundwater management. EUGRI is a gateway to provide a &apos;one stop shop&apos; for information provided by research projects, legislation, standards, best practice and other technical guidance and policy/regulatory publications from the EC, participating Member and Accession States and from various international networks dealing with groundwater and land management issues. Different types of user can access information through different windows according to their needs. EUGRIS will provide its visitors with summary information (digests) and links to sources of more detailed and/or original information in a scaleable holistic and contexturally meaningful way. EUGRIS is being built in three stages: the design of the information system, the development of its software implementation, and the population of the system with information. The presentation is focussed on the concept of the development of the information system with the individual work packages. In the second part of the lecture in particular the work procedures are presented for the content wise replenishment by EUGRIS. The data collation for the proven pilot countries and the production of a European research data base, which opens contents and results of European-wide locked and current projects, form the emphasis thereby.

    While sampling stratospheric aerosols during July--August 1980 a plume of &apos;'fresh'&apos; volcanic debris was observed in the Northern hemisphere. The origin of this material seems to be a poorly documented explosive eruption of Gareloi valcano in the Aleutian Islands. The debris was sampled at an altitude of 19.2 km: almost twice the height of observed eruption clouds. Such remote, unobserved or poorly documented eruptions may be a source that helps maintain the &apos;'ambient'&apos; stratospheric aerosol background.

    Magnetooptical measurements have been performed on {beta}&apos;&apos;-(BEDT-TTF)(TCNQ) using the cavity perturbation techniques. {beta}&apos;&apos;-(BEDT-TTF)(TCNQ) has very exotic Fermi surface (FS). Several harmonic resonances were observed at various angles. We consider these resonances as q1D-periodic orbit resonance. The obtained Fermi velocity and the scattering time are 4.4x10{sup 4} m/s and 2.1x10{sup -11} s, respectively. When the magnetic field was rotated in the b{sup *}a-plane, the similar resonances are observed. According to these results, the FS topology of the system at low temperature is discussed.

    Solar magnetized &apos;tornadoes&apos;, a phenomenon discovered in the solar atmosphere, appear as tornado-like structures in the corona but are rooted in the photosphere. Like other solar phenomena, solar tornadoes are a feature of magnetized plasma and therefore differ distinctly from terrestrial tornadoes. Here we report the first analysis of solar &apos;tornadoes&apos; (two papers which focused on different aspects of solar tornadoes were published in the Astrophysical Journal Letters and Nature, respectively, during the revision of this Letter). A detailed case study of two events indicates that they are rotating vertical magnetic structures probably driven by underlying vortex flows in the photosphere. They usually exist as a group and are related to filaments/prominences, another important solar phenomenon whose formation and eruption are still mysteries. Solar tornadoes may play a distinct role in the supply of mass and twists to filaments. These findings could lead to a new explanation of filament formation and eruption.

  8. Quarks: Two&apos;s company, three a crowd?

    International Nuclear Information System (INIS)

    Last year, careful measurements by the experiments studying electron positron annihilation in CERN&apos;s new LEP ring and at Stanford&apos;s SLC linear collider showed that the conventional list of the basic constituents of matter is complete. Three types of particles (electron, muon and tau) interacting under the weak nuclear force are linked to six quarks - the constituents of nuclear matter - grouped pairwise into three distinct families (&apos;up&apos; and &apos;down&apos;, &apos;strange&apos; and &apos;charm&apos;, &apos;beauty&apos; and &apos;top&apos;). The question now is to understand why this sixquark model works

    Upper Muschelkalk (Middle Triassic) carbonates produce natural gas at Coevorden field in the NE Netherlands. This is currently the only field that produces gas from this succession although several other prospects have been identified nearby. In order to help develop these hydrocarbons, this study proposes a facies and reservoir model of the Upper Muschelkalk in the NE Netherlands together with a regional framework intended to assist in further evaluation. Distribution of facies and reservoir properties of the Upper Muschelkalk carbonates in the NE Netherlands indicate deposition on a storm-dominated epeiric ramp with a very low gradient. The predominantly muddy and marly lithofacies types in proximal and distal parts of the ramp gradually interfinger with a shoreline-detached &apos;'shoal'&apos;-like ooidal grainstone complex. The best reservoir quality (permeability up to 60 mD) is recognised within dolomitised peloid ooid grainstones. These are interpreted as high-energy backshoal deposits. Reservoir quality decreases in the limestone-dominated &apos;'shoal'&apos; facies and the muddier foreshoal facies. A four-fold hierarchy of depositional cycles describes the systematic and thus predictable vertical variation in reservoir quality (permeability) and quantity (net-to-gross). High-resolution correlation suggests that medium-scale cycles (5 to 15 metres thick) can be traced for hundreds of kilometres. Small-scale cycles (1 to 3 metres thick) are persistent for several tens of kilometres and have sheet-like geometries. Individual reservoir units (several decimetres thick) appear to be laterally continuous over a maximum of a few kilometres although internal flow barriers might be expected. Mapping of Upper Muschelkalk thickness and facies has clearly defined backshoal, &apos;'shoal'&apos; and foreshoal facies belts with distinctly different reservoir characteristics. Typically, reservoir quality and quantity decrease with increasing

    In a recent work [Phys. Rev. A 84, 033804 (2011)] we considered elastic scattering of a twisted particle from a plane wave and studied how the orbital helicity of the twisted particle changes after scattering. We showed that for realistic beams the relative change can be small, |m{sup &apos;}-m|/m<<1, thus resolving a controversy which existed in the literature. In this Addendum, using a more accurate analysis, we argue that in the kinematics of Compton backscattering a stronger statement is true: in fact m{sup &apos;}{approx_equal}m, and the difference |m{sup &apos;}-m| even by a single unit is already suppressed.

    Full Text Available Com o contínuo crescimento de uso de compósitos poliméricos estruturais na produção industrial de peças aeronáuticas, torna-se imperativo desenvolver técnicas de reparos de danos aplicáveis aos diversos tipos de laminados. O procedimento normalmente utilizado para definir o reparo de compósitos laminados, envolve a simulação do dano em corpos-de-prova representativos dos componentes. Este trabalho apresenta a técnica de reparo estrutural, tipo chanfro, de laminados de carbono/epóxi de aplicação aeronáutica, pelo uso de tecido de carbono/epóxi. Os laminados de carbono/epóxi, sem e com reparos, foram submetidos ao condicionamento ambiental em duas condições diferentes (ambiente: 23 ± 5ºC e 50 ± 5 % de umidade relativa e úmida: 65 ± 5ºC e 95 ± 5 % de umidade relativa, e os reparos foram realizados com quatro diferentes sobreposições das camadas de tecido de carbono (9,0; 12,7; 15,0 e 20,0 mm. Todas as famílias de reparo foram submetidas ao carregamento em tração em temperaturas ambiente e elevada (82ºC. Os melhores resultados da propriedade mecânica dos laminados reparados foram obtidos com as sobreposições de 15,0 e 20,0 mm, recompondo a resistência em 80,7 e 84,0%, respectivamente, em relação ao laminado sem reparo. O condicionamento com umidade e temperatura elevadas diminuiu a resistência em tração em até 90% dos laminados reparados, favorecendo a falha por descolamento entre o laminado base e o reparo (falha no adesivo.The continuous use of structural polymer composites in the aeronautical industry has required the development of repairing techniques of damages found in different types of laminates.

    The concept of &apos;green&apos; chemotherapy by employing targeted nanoparticle mediated delivery to enhance the efficacy of phytomedicines is reported. Poly (lactide-co-glycolide) (PLGA) nanoparticles encapsulating a well known nutraceutical namely, grape seed extract (GSE)-&apos;NanoGSE&apos;-was prepared by a nanoprecipitation technique. The drug-loaded nanoparticles of size {approx} 100 nm exhibited high colloidal stability at physiological pH. Molecular receptor targeting of this nanophytomedicine against folate receptor over-expressing cancers was demonstrated in vitro by conjugation with a potential cancer targeting ligand, folic acid (FA). Fluorescence microscopy and flow cytometry data showed highly specific cellular uptake of FA conjugated NanoGSE on folate receptor positive cancer cells. Studies were also conducted to investigate the efficiency of targeted (FA conjugated) versus non-targeted (non-FA conjugated) nanoformulations in causing cancer cell death. The IC{sub 50} values were lowered by a factor of {approx} 3 for FA-NanoGSE compared to the free drug, indicating substantially enhanced bioavailability to the tumor cells, sparing the normal ones. Receptor targeting of FA-NanoGSE resulted in a significant increase in apoptotic index, which was also quantified by flow cytometry and fluorescence microscopy. This in vitro study provides a basis for the use of nanoparticle mediated delivery of anticancer nutraceuticals to enhance bioavailability and effectively target cancer by a &apos;green&apos; approach.

    &apos;'Recycled'&apos; millisecond pulsars are a variety of rapidly spinning neutron stars that typically show thermal X-ray radiation due to the heated surface of their magnetic polar caps. Detailed numerical modeling of the rotation-induced thermal X-ray pulsations observed from recycled millisecond pulsars, including all relevant relativistic and stellar atmospheric effects, has been identified as a promising approach towards an astrophysical determination of the true neutron star mass-radius relation, and by extension the state of cold matter at densities exceeding those of atomic nuclei. Herein, I review the basic model and methodology commonly used to extract information regarding neutron star structure from the pulsed X-ray radiation observed from millisecond pulsars. I also summarize the results of past X-ray observations of these objects and the prospects for precision neutron star mass-radius measurements with the upcoming Neutron Star Interior Composition Explorer (NICER) X-ray timing mission.

This first congress about the deconstruction of nuclear power plants was combined with an exhibition in the fully equipped nuclear training power plant Zwentendorf. The exhibitors had the opportunity to present and test their products in the ambience of a real nuclear power plant, close to original plant components. The visitors got a general overview of the on-site conditions. During the lectures the process of decommissioning and dismantling of a nuclear power plant was described, problems within this process were discussed, and possible solutions were recommended. The congress influenced significantly the dialogue of all parties involved and contributed to an extensive exchange of knowledge and experience.

  19. The current status of &apos;&apos;Troitsk nu-mass&apos;&apos; experiment in search for sterile neutrino

    International Nuclear Information System (INIS)

    We propose a new experiment to search for a sterile neutrino in a few keV mass range at the &apos;&apos;Troitsk nu-mass&apos;&apos; facility. The expected signature corresponds to a kink in the electron energy spectrum in tritium beta-decay. The new goal compared to our previous experiment will be precision spectrum measurements well below end point. The experimental installation consists of a windowless gaseous tritium source and a high resolution electromagnetic spectrometer. We estimate that the current bounds on the sterile neutrino mixing parameter can be improved by an order of magnitude in the mass range under 5 keV without major upgrade of the existing equipment. Upgrades of calibration, data acquisition and high voltage systems will allow to improve the bounds by another order of magnitude

    &apos;'Recycled'&apos; millisecond pulsars are a variety of rapidly spinning neutron stars that typically show thermal X-ray radiation due to the heated surface of their magnetic polar caps. Detailed numerical modeling of the rotation-induced thermal X-ray pulsations observed from recycled millisecond pulsars, including all relevant relativistic and stellar atmospheric effects, has been identified as a promising approach towards an astrophysical determination of the true neutron star mass-radius relation, and by extension the state of cold matter at densities exceeding those of atomic nuclei. Herein, I review the basic model and methodology commonly used to extract information regarding neutron star structure from the pulsed X-ray radiation observed from millisecond pulsars. I also summarize the results of past X-ray observations of these objects and the prospects for precision neutron star mass-radius measurements with the upcoming Neutron Star Interior Composition Explorer (NICER) X-ray timing mission.

    To expand the search for central pulmonary arteries in six patients with absence of cardiac-pulmonary continuity, computerized axial tomography (CAT) of the chest was performed. The CAT scans were compared with previous arteriograms and pulmonary vein wedge angiograms. Three patients with type IV truncus arteriosus were studied, and none had a central, right or left pulmonary artery on CAT scan. However, two patients with tetralogy of Fallot with pulmonary atresia and a patent ductus arteriosus to the right lung demonstrated the presence of a left pulmonary artery. In addition, one child with truncus arteriosus with &apos;'absent'&apos; left pulmonary artery demonstrated a left pulmonary artery on the CAT scan. The CAT scan may therefore enhance our ability to search for disconnected pulmonary arteries in children with complex cyanotic congenital heart disease.

    The Inden opencast lignite mine is located some 20 km to the north-east of Aachen in Germany&apos;s Rhineland. After the end of lignite mining around the year 2030, a lake measuring some 11.8 km{sup 2} is planned to be created. It will mainly be filled with water from the river Rur flowing past in the immediate vicinity of the opencast mine. Filling the lake volume of some 800 million m{sup 3} will take 20 to 25 years. During the past ten years, the basic water management questions arising in connection with the creation of the In den mine&apos;s residual lake were settled within the scope of the state-planning approval procedure.lt could be demonstrated by means of a numeric river catchment model that the envisaged withdrawal of water from the Rur is feasible and compatible with the water body&apos;s ecological and hydromorphological targets as well as its industrial use.

  5. Iran&apos;s &apos;Risk-Taking&apos; in Perspective

    2008-07-01

    Assessing any state&apos;s intentions is a difficult undertaking - especially at a specific moment in time. When a state is considered hostile, its behaviour erratic, and its system opaque, what is difficult under normal circumstances becomes nearly impossible. It may thus often seem prudent to attribute the worst of intentions to such states, but this can create a self-fulfilling prophecy. Iran with its revolutionary pretensions, fiery rhetoric and nuclear ambitions, is a case in point, since it is particularly difficult to &apos;read&apos;. Located in the centre of a geo-politically sensitive and conflict-driven area, Iran is in a position to influence - positively or otherwise - the Persian Gulf, the Caucasus, the Middle East and South Asia. This influence may furthermore be expanding as a result of the weakening of Iraq and Lebanon, divisions among the Palestinians, and the more general rise of the Shi&apos;i across the broader region. Add to this the ambiguous aims of Iran&apos;s nuclear programme and the shadow this has already thrown across the region, and the need to assess Iran&apos;s intentions accurately appears crucial. Here, Iran&apos;s past behavior may provide some help, especially when it comes to Iran&apos;s proclivity for risk taking - provided the acquisition of a nuclear capability does not alter Iran&apos;s intentions or behavior so as to make the past irrelevant. Some commentators believe that Iran&apos;s ideology and past behaviour suggest that a nuclear-capable Iran will be inclined to take on a high level of risk, without concern for the potential costs of this recklessness, and that Iran may perhaps even welcome the risks involved. By contrast, the recent National Intelligence Estimate (NIE), a composite of US intelligence agency estimates, has concluded that Iran&apos;s &apos;decisions are guided by a cost-benefit approach&apos; and therefore &apos;may be more vulnerable to influence&apos; than they had previously (i.e.2005) judged.

    It is now well known that details in the intermolecular potential can significantly affect the qualitative features of a phase diagram where temperature is plotted against density for the coexistence curves among fluid and solid phases. While previous calculations of phase diagrams have assumed a time-invariant potential function, this report concerns the phase diagram for &apos;'breathing'&apos; molecules, i.e., molecules whose strength of intermolecular attraction fluctuates in time. Such fluctuations can occur in biomacromolecules where an active site can switch between &apos;'on'&apos; and &apos;'off'&apos; positions. Phase-equilibrium calculations were performed for molecules that have a periodic (breathing) attractive force in addition to the conventional intermolecular forces. The phase diagram for such molecules is as expected when the &apos;'breathing'&apos; properties are independent of density. However, when (more realistically), the &apos;'breathing'&apos; properties are density dependent, the phase diagram exhibits dramatic changes. These calculations may be useful for interpreting experimental data for protein precipitation, for plaque formation in blood vessels and for scaffold-supported tissue formation.

  8. Why Germany&apos;s &apos;Messy&apos; energy transition should be a lesson to other nations

    International Nuclear Information System (INIS)

    Germany&apos;s so-called &apos;&apos;energy transition&apos;&apos; (&apos;'Energiewende'&apos;) is increasingly drawing the intention of the international community - but it seems for all the wrong reasons. US Senator Lamar Alexander said recently that German energy policy is one of the reasons the US should not abandon nuclear, but actually encourage increased investment in nuclear power plants. Alexander&apos;s remarks were made in an article published by the US Nuclear Energy Institute, in which he outlined his reasons why the US should not follow Germany&apos;s lead. Alexander rightly pointed out that the cost of attempting to replace nuclear power with wind, solar, and accompanying infrastructure is estimated by the German government at some 1.2 trillion US dollars (about 1 trillion Euros). The senator also made the point that Germany &apos;&apos;does not produce enough reliable, baseload energy for an important manufacturing economy&apos;&apos;. He also expressed concern at Germany&apos;s reliance on buying natural gas from Russia. While Germany has been forcing the closure of nuclear power plants others, including the oil-rich United Arab Emirates (UAE), have been investing in new nuclear, Alexander said. Judging from Alexander&apos;s remarks, it seems that Germany&apos;s energy transition experience will, after all, have a long-lasting legacy. That legacy will be a valuable lesson to other major industrialised nations in why they should not follow Germany&apos;s lead in abandoning a sensible energy mix, if they wish to maintain and develop economic and industrial productivity while keeping to international commitments to tackle climate change.

    Apolipoprotein E4 (ApoE4), one of three common isoforms of ApoE, is a major risk factor for late-onset Alzheimer disease (AD). ApoE-deficient mice, as well as mice expressing human ApoE4, display impaired learning and memory functions and signs of neurodegeneration. Moreover, ApoE protects against high-fat (HF) diet induced neurodegeneration by its role in the maintenance of the integrity of the blood-brain barrier. The influence of a HF diet on the progression of AD-like cognitive and neuropathological changes was assessed in wild-type (WT), human ApoE4 and ApoE-knockout (ApoE-/-) mice to evaluate the modulatory role of ApoE in this process. From 12 months of age, female WT, ApoE4, and ApoE-/- mice were fed either a standard or a HF diet (19% butter, 0.5% cholate, 1.25% cholesterol) throughout life. At 15 months of age mice performed the Morris water maze, evaluating spatial learning and memory. ApoE-/- showed increased spatial learning compared to WT mice (p = 0.009). HF diet improved spatial learning in WT mice (p = 0.045), but did not affect ApoE4 and ApoE-/- mice. Immunohistochemical analyses of the hippocampus demonstrated increased neuroinflammation (CD68) in the cornu ammonis 1 (CA1) region in ApoE4 (p = 0.001) and in ApoE-/- (p = 0.032) mice on standard diet. HF diet tended to increase CD68 in the CA1 in WT mice (p = 0.052), while it decreased in ApoE4 (p = 0.009), but ApoE-/- remained unaffected. A trend towards increased neurogenesis (DCX) was found in both ApoE4 (p = 0.052) and ApoE-/- mice (p = 0.068). In conclusion, these data suggest that HF intake induces different effects in WT mice compared to ApoE4 and ApoE-/- with respect to markers for cognition and neurodegeneration. We propose that HF intake inhibits the compensatory mechanisms of neuroinflammation and neurogenesis in aged female ApoE4 and ApoE-/- mice. PMID:27171180

    Service water has been most widely used as a drilling mud at the &apos;'Permneft''&apos; union. Emulsion mud and emulsion mud-carbonated drilling mud are also widely used. In unstable rock areas, flushing is conducted using calcium chloride mud drilling solutions and mud drilling solutions with natural subsalt mineralization. The use of various types of drilling muds is analyzed. The following were the primary indicators in the analysis: the specific weight of the expenditures on drilling solution materials in the overall cost of borehole construction and the expenses on materials for 1 meter of drilling. The types of drilling solutions recommended for use in different fields in specific geological conditions are determined. The drilling solution standards are compared based on the results of an analysis and the reference materials of the All-Union Scientific Research Institute on Comprehensive Oil Solutions. An examination proceedure is described, together with the regulation acceptances and directions for improving them.

    The authors continue the series of papers describing the results of a photometric survey of open star clusters, primarily in the southern hemisphere, taken in the u&apos;g'r'i'z&apos; filter system. The entire observed sample covered more than 100 clusters, but here they present data only on NGC 188, which is one of the oldest open clusters known in the Milky Way. They fit the Padova theoretical isochrones to the data. Assuming a solar metallicity for NGC 188, they find a distance of 1700 {+-} 100 pc, an age of 7.5 {+-} 0.7 Gyr, and a reddening E(B-V) of 0.025 {+-} 0.005. This yields a distance modulus of 11.23 {+-} 0.14.

  16. ApoE4-specific Misfolded Intermediate Identified by Molecular Dynamics Simulations.

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available The increased risk of developing Alzheimer's disease (AD is associated with the APOE gene, which encodes for three variants of Apolipoprotein E, namely E2, E3, E4, differing only by two amino acids at positions 112 and 158. ApoE4 is known to be the strongest risk factor for AD onset, while ApoE3 and ApoE2 are considered to be the AD-neutral and AD-protective isoforms, respectively. It has been hypothesized that the ApoE isoforms may contribute to the development of AD by modifying the homeostasis of ApoE physiological partners and AD-related proteins in an isoform-specific fashion. Here we find that, despite the high sequence similarity among the three ApoE variants, only ApoE4 exhibits a misfolded intermediate state characterized by isoform-specific domain-domain interactions in molecular dynamics simulations. The existence of an ApoE4-specific intermediate state can contribute to the onset of AD by altering multiple cellular pathways involved in ApoE-dependent lipid transport efficiency or in AD-related protein aggregation and clearance. We present what we believe to be the first structural model of an ApoE4 misfolded intermediate state, which may serve to elucidate the molecular mechanism underlying the role of ApoE4 in AD pathogenesis. The knowledge of the structure for the ApoE4 folding intermediate provides a new platform for the rational design of alternative therapeutic strategies to fight AD.

    The characterization of ever smaller and fainter extrasolar planets requires an intricate understanding of one&apos;s data and the analysis techniques used. Correcting the raw data at the 10{sup -4} level of accuracy in flux is one of the central challenges. This can be difficult for instruments that do not feature a calibration plan for such high precision measurements. Here, it is not always obvious how to de-correlate the data using auxiliary information of the instrument and it becomes paramount to know how well one can disentangle instrument systematics from one&apos;s data, given nothing but the data themselves. We propose a non-parametric machine learning algorithm, based on the concept of independent component analysis, to de-convolve the systematic noise and all non-Gaussian signals from the desired astrophysical signal. Such a &apos;blind&apos; signal de-mixing is commonly known as the &apos;Cocktail Party problem&apos; in signal processing. Given multiple simultaneous observations of the same exoplanetary eclipse, as in the case of spectrophotometry, we show that we can often disentangle systematic noise from the original light-curve signal without the use of any complementary information of the instrument. In this paper, we explore these signal extraction techniques using simulated data and two data sets observed with the Hubble Space Telescope NICMOS instrument. Another important application is the de-correlation of the exoplanetary signal from time-correlated stellar variability. Using data obtained by the Kepler mission we show that the desired signal can be de-convolved from the stellar noise using a single time series spanning several eclipse events. Such non-parametric techniques can provide important confirmations of the existent parametric corrections reported in the literature, and their associated results. Additionally they can substantially improve the precision exoplanetary light-curve analysis in the future.

    The ε4 allele of the apolipoprotein E gene (APOE4) is associated with cognitive decline during aging, is the greatest genetic risk factor for Alzheimer's disease and has links to other neurodegenerative conditions that affect cognition. Increasing evidence indicates that APOE genotypes differentially modulate the function of the cerebrovasculature (CV), with apoE and its receptors expressed by different cell types at the CV interface (astrocytes, pericytes, smooth muscle cells, brain endothelial cells). However, research on the role of apoE in CV dysfunction has not advanced as quickly as other apoE-modulated pathways. This review will assess what aspects of the CV are modulated by APOE genotypes during aging and under disease states, discuss potential mechanisms, and summarize the therapeutic significance of the topic. We propose that APOE4 induces CV dysfunction through direct signaling at the CV, and indirectly via modulation of peripheral and central pathways. Further, that APOE4 predisposes the CV to damage by, and exacerbates the effects of, additional risk factors (such as sex, hypertension, and diabetes). ApoE4-induced detrimental CV changes include reduced cerebral blood flow (CBF), modified neuron-CBF coupling, increased blood-brain barrier leakiness, cerebral amyloid angiopathy, hemorrhages and disrupted transport of nutrients and toxins. The apoE4-induced detrimental changes may be linked to pericyte migration/activation, astrocyte activation, smooth muscle cell damage, basement membrane degradation and alterations in brain endothelial cells.

    The microbial catabolic activity of biological reactors can be increased by up to 75% through external stimulation with intermittent stress loads at intervals of several minutes. Under these process conditions, the &apos;&apos;biological resonance&apos;&apos; phenomenon determines the system and leads to an increased synthesis of enzymes. In addition to computer simulations, experiments with activated sludge were carried out in a 10-litre bioreactor. By modulating the stress intervals, a permanent increase in catabolic activity of about 60% was achieved during these experiments. By relying on the &apos;&apos;biological resonance&apos;&apos; phenomenon, the required reaction volume of biological treatment units can probably be reduced by up to 40%. (orig.)

    Full Text Available Abstract Background Apolipoprotein E (apoE is postulated to affect brain Aβ levels through multiple mechanisms--by altering amyloid precursor protein (APP processing, Aβ degradation, and Aβ clearance. We previously showed that an apoE-derived peptide containing a double repeat of the receptor-binding region was similarly effective in increasing APP processing in vivo. Here, we further examined whether peptides containing tandem repeats of the apoE receptor-binding region (amino acids 141-149 affected APP trafficking, APP processing, and Aβ production. Results We found that peptides containing a double or triple tandem repeat of the apoE receptor-binding region, LRKLRKRLL, increased cell surface APP and decreased Aβ levels in PS1-overexpressing PS70 cells and in primary neurons. This effect was potentiated by a sequential increase in the number of apoE receptor-binding domain repeats (trimer > dimer > monomer. We previously showed that the apoE dimer increased APP CTF in vivo; to determine whether the dimer also affected secreted APP or Aβ levels, we performed a single hippocampal injection of the apoE dimer in wild-type mice and analyzed its effect on APP processing. We found increased sAPPα and decreased Aβ levels at 24 hrs after treatment, suggesting that the apoE dimer may increase α-secretase cleavage. Conclusions These data suggest that small peptides consisting of tandem repeats of the apoE receptor-binding region are sufficient to alter APP trafficking and processing. The potency of these peptides increased with increasing repeats of the receptor binding domain of apoE. In addition, in vivo administration of the apoE peptide (dimer increased sAPPα and decreased Aβ levels in wild-type mice. Overall, these findings contribute to our understanding of the effects of apoE on APP processing and Aβ production both in vitro and in vivo.

    This paper investigates rationale explanations of OPEC&apos;s strategies. Accounting for market characteristics in particular the sluggishness of demand and supply allows to explain price jumps as rational OPEC strategies from a narrow economic perspective (up and down) as well as from political objectives (at least up) due to the political payoff from standing up against the &apos;West&apos;. Although the temptation to accrue this political payoff was and remains high, the narrow economic profit motive coupled with an imperfect cooperation among OPEC members explains past price volatility and high prices much better than the usual reference to political events. A more specific prediction is that OPEC will switch back to setting prices since the current quantity strategy encourages oil importing countries to appropriate rents in particular in connection with the need to mitigate global warming.

    Pulverizer throughput is determined by the coal fineness desired for a given coal. However, compromising on coal fineness when your pulverizer isn&apos;t up to scratch can increase NOx and cause many furnace problems. Your least costly option for increasing pulverizer capacity is to pay careful attention to key dimensions and critical tolerances during your next overhaul. 11 figs.

  9. Crisis - Weisskopf&apos;s view

    International Nuclear Information System (INIS)

    &apos;We are facing a crisis, not only in particle physics but in the whole of fundamental science&apos;, said Victor Weisskopf, doyen of quantum physics, during his traditional summer CERN stopover. &apos;Basic science - science for its own sake - and especially high energy physics, is really in danger.&apos; As well as explaining how this has come about, the former CERN Director General (1961-5) proposed action to reverse the trend. Rather than dividing science into the conventional &apos;big&apos; and &apos;small&apos; camps, he slices across another axis. On one hand there is obviously applicable &apos;terrestrial science&apos; - biology, medicine, solid state, much of the nuclear sector, nonlinear behaviour, chaos,....all directly connected with processes that happen on Earth. On the other there is &apos;cosmic science&apos; - astronomy, astrophysics, particle physics and some of the nuclear sector - addressing deeper issues, not attainable naturally on this planet at all, and where applications are less immediately obvious. (This classification is not completely watertight - even cosmic science can, and does, foster immediate spinoff, Weisskopf points out, citing Georges Charpak&apos;s detector work.) Tracing the evolution of science in this century, Weisskopf sees the rapid evolution of American influence in the 1930s as a turning point. Before then, the United States had not been in the front line, and it had been important for US researchers to spend some time in Europe

  10. Proliferation Resistance and Safeguards by Design: The Safeguardability Assessment Tool Provided by the INPRO Collaborative Project &apos;'INPRO'&apos; (Proliferation Resistance and Safeguardability Assessment)

    International Nuclear Information System (INIS)

    Since the INPRO Collaborative Project on Proliferation Resistance and Safeguardability Assessment Tools (PROSA) was launched in 2011, Member State experts have worked with the INPRO Section and the IAEA Department of Safeguards to develop a revised methodology for self-assessment of sustainability in the area of proliferation resistance of a nuclear energy system (NES). With the common understanding that there is &apos;&apos;no proliferation resistance without safeguards&apos;&apos; the revised approach emphasizes the evaluation of a new &apos;User Requirement&apos; for &apos;'safeguardability'&apos;, that combines metrics of effective and efficient implementation of IAEA Safeguards including &apos;'Safeguards-by-Design'&apos; principles. The assessment with safeguardability as the key issue has been devised as a linear process evaluating the NES against a &apos;&apos;Basic Principle&apos;&apos; in the area of proliferation resistance, answering fundamental questions related to safeguards: 1) Do a State&apos;s legal commitments, policies and practices provide credible assurance of the exclusively peaceful use of the NES, including a legal basis for verification activities by the IAEA? 2) Does design and operation of the NES facilitate the effective and efficient implementation of IAEA safeguards? To answer those questions, a questionnaire approach has been developed that clearly identifies gaps and weaknesses. Gaps include prospects for improvements and needs for research and development. In this context, the PROSA approach assesses the safeguardability of a NES using a layered &apos;&apos;Evaluation Questionnaire&apos;&apos; that defines Evaluation Parameters (EP), EP-related questions, Illustrative Tests and Screening Questions to present and structure the evidence of findings. An integral part of the assessment process is Safeguards-by-Design, the identification of potential diversion, misuse and concealment strategies (coarse diversion path

    In 192 sleep-healthy subjects (18 to 65 y) effects of nocturnal aircraft noise on sleep, stress, performance and subjective factors were investigated in 2240 nights under laboratory and field conditions. In the sleep lab, 112 volunteers were subjected to aircraft noise events by varying numbers and noise levels during 9 nights within a period of 13 nights. 16 further subjects served as control group (i.e. without any noise). 64 subjects were studied in the vicinity of Cologne-Bonn airport during 9 nights. Polysomnographical and acoustical recordings, determination of excretion rates of stress hormones from night urines, performance tests and questionnaires were conducted during all days for the assessment of nocturnal aircraft noise effects. By simultaneous recording of electrophysiological and acoustical data the probability of noise induced awakenings was estimated. Performance and most of psychological parameters did not show significant dose-effect relationships, whereas annoyance did. Epinephrine and norepinephrine did not change under aircraft noise, cortisol did change only in the lab. In the lab, a comparison between all noisy nights and noise-free baseline nights exhibited a non-significant 2-min. reduction of sleep and a 4-min. decrease of slow-wave sleep. In the field, awakenings caused by aircraft noise were detected above a threshold of 33 dB(A) &apos;&apos;at the sleeper&apos;s ear&apos;&apos;. All effects were much less pronounced in the field than in the lab. For the first time, precise dose-effect curves between maximum aircraft noise event levels and electrophysiologically detectable awakenings, and a threshold were empirically established. The results of these studies broadens the knowledge on aircraft noise induced sleep disturbances and immediate consequences for the next day. (orig.)

    Many of the planned upgrading measures of Ukrainian VVER plants and of the unique Armenian power plant (Medzanor) are financed by the European Union (EU) through the TACIS program. The &apos;&apos;2+2&apos;&apos; approach implies a deep collaboration between Ukrainian or Armenian regulatory authorities, local operating organizations and EU organizations. This approach allows: - a smooth adaptation of western technologies to VVERs, - a comprehensive checking of Ukrainian, Armenian and western regulatory requirements, and - the transfer of know-how to the Ukrainian and Armenian organizations. This report presents the principles applied for &apos;&apos;2+2&apos;&apos; approach as well as a summary of the main recommendations given in the framework of the licensing process.

    Different apolipoprotein combinations explain most of the functional differences between plasma lipoproteins. This emphasizes the pivotal role of apolipoproteins in the homeostasis and physiological control of lipid metabolism. Genetic polymorphisms of apolipoprotein (apo)A-I/C-III/A-IV, apoE and apoB have been suggested to modulate plasma lipid levels as well as the risk of coronary artery disease and stroke. Carotid artery intima-media thickness has been shown to represent preclinical atherosclerosis and has, therefore, been used as a surrogate in quantifying the early stages of atherosclerosis. The effects of the polymorphisms in apoA-I/C-III/A-IV and apoB on carotid intima-media thickness are poorly known. The corresponding influence of apoE polymorphisms has been studied more extensively, but the results are not yet conclusive. In this review, these results are presented in detail and the potential reasons and mechanisms for the discrepancies are discussed. PMID:19804074

    This project had two main objectives. The first major goal was to develop new, powerful computational simulation capabilities. It was important that these tools have the combination of the accuracy needed to describe the quantum mechanical nature of nanoscale systems and the efficiency required to be applied to realistic, experimentally derived materials. The second major goal was to apply these computational methods to calculate and predict the properties of quantum dots--initially composed of silicon, but then of other elements--which could be used to build novel nanotechnology devices. The driving factor of our purpose has been that, through the development and successful application of these tools, we would generate a new capability at LLNL that could be used to make nanostructured materials &apos;'smarter'&apos;, e.g., by selectively predicting how to engineering specific, desired properties. To carry out the necessary work to successfully complete this project and deliver on our goals, we established a two-pronged effort from the beginning: (1) to work on developing new, more efficient algorithms and quantum simulation tools, and (2) to solve problems and make predictions regarding properties of quantum dots which were being studied experimentally here at Livermore.

    Abusive head trauma (AHT) in infants is usually diagnosed using a multi-disciplinary approach by investigating the circumstances and identifying morphological indicators, for example, subdural hematomas (SDHs), subdural hygromas (SDHys), retinal haemorrhages and encephalopathy. The present morphological study investigates the incidence, radiological characteristics and non-radiological co-factors of bridging vein thrombosis (BVT) in infants with AHT. From 2002 to 2013, computed tomography (CT) and magnetic resonance imaging (MRI) material of 628 infants aged 0-2 years were analysed retrospectively. If available, medicolegal expert opinions were additionally considered. Cases with SDHs and/or SDHys were identified and systematically evaluated as to the presence and characteristics of BVT. SDHs and/or SDHys were present in 29 of the 81 cases exhibiting morphological abnormalities in the initial CT. Among these, 11 cases (40 %) had BVT (mean age = 5.0 months). BVT could be best depicted in the T1-weighted spin echo and T2*/susceptibility-weighted MRI. In one case, BVT could be depicted indirectly using time-of-flight MR venography. The predominant (73 %) BVT shape was found to be tadpole-like (&apos;&apos;Tadpole Sign&apos;&apos;). In the absence of appropriate accidental trauma, BVT appears to be a strong indicator of AHT. Therefore, the BVT/Tadpole Sign represents compelling cause to search for other signs of AHT. (orig.)

  17. Proposal of a simple screening method for a rapid preliminary evaluation of &apos;&apos;heavy metals&apos;&apos; mobility in soils of contaminated sites

    Risks associated to &apos;&apos;heavy metals&apos;&apos; (HM) soil contamination depend not only on their total content but, mostly, on their mobility. Many extraction procedures have been developed to evaluate HM mobility in contaminated soils, but they are generally time consuming (especially the sequential extraction procedures (SEPs)) and consequently applicable on a limited number of samples. For this reason, a simple screening method, applicable even &apos;&apos;in field&apos;&apos;, has been proposed in order to obtain a rapid evaluation of HM mobility in polluted soils, mainly focused on the fraction associated to Fe and Mn oxide/hydroxides. A buffer solution of trisodium citrate and hydroxylamine hydrochloride was used as extractant for a single-step leaching test. The choice of this buffered solution was strictly related to the possibility of directly determining, via titration with dithizone (DZ), the content of Zn, Cu, Pb and Cd, which are among the most representative contaminants in highly mineralised soils. Moreover, the extraction solution is similar, aside from for the pH value, which is the one used in the BCR SEP second step. The analysis of bivalents ions through DZ titration was exploited in order to further simplify and quicken the whole procedure. The proposed method generically measures, in few minutes, the concentration of total extractable &apos;&apos;heavy metals&apos;&apos; expressed as molL{sup -1} without distinguishing between elements. The proposed screening method has been developed and applied on soil samples collected from rural, urban and mining areas, representing different situation of soil contamination. Results were compared with data obtained from the BCR procedure. The screening method demonstrated to be a reliable tool for a rapid evaluation of metals mobility. Therefore, it could be very useful, even &apos;&apos;in field&apos;&apos;, both to guide the sampling activity on site and to monitor the efficacy of the subsequent

    The Anadenathera macrocarpa, Schinus molle, Hymenaea courbaril, Cariniana legalis, Solidago microglossa and Stryphnodendron barbatiman, were collected &apos;&apos;in natura&apos;&apos; samples (leaves, flowers, barks and seeds) from different commercial suppliers. The pharmaco-active compounds in ethanolic extracts had been made by the Mato Grosso Federal University (UFMT). The energy-dispersive x-ray fluorescence (ED-XRF) spectrometry was used for the elemental analysis in different parts of the plants and respective ethanolic extracts. The Ca, Cl, Cu, Fe, K, Mg, Mn, Na, Ni, P, Rb, S, Sr and Zn concentrations were determined by the fundamental parameters method. Some specimens showed a similar inorganic profile for &apos;&apos;in natura&apos;&apos; and ethanolic extract samples and some ones showed a distinct inorganic profile. For example, the Anadenathera macrocarpa showed a similar concentration in Mg, P, Cu, Zn and Rb elements in &apos;&apos;in natura&apos;&apos; and ethanolic extract samples; however very different concentration in Na, S, Cl, K , Ca, Mn, Fe and Sr was observed in distinctive samples. The Solidago microglossa showed the K, Ca, Cl, S, Mg, P and Fe elements as major constituents in both samples, suggesting that the extraction process did not affect in a considerable way the &apos;&apos;in natura&apos;&apos; inorganic composition. The elemental composition of the different parts of the plants (leaves, flowers, barks and seeds) has been also determined. For example, the Schinus molle specimen showed P, K, Cl and Ca elements as major constituents in the seeds, Mg, K and Sr in the barks and Mg, S, Cl and Mn in the leaves, demonstrating a differentiated elementary distribution. These inorganic profiles will contribute to evaluate the quality control of the Brazilian herbaceous trade and also will assist to identify which parts of the medicinal plants has greater therapeutic effect.

    Objective: To describe the MR appearance following autogenous osteochondral &apos;'plug'&apos; transfer for the treatment of focal chondral defects of the knee. Design and patients: Twenty-nine 1.5-T MR knee studies including dynamic gadolinium enhancement were performed on 21 patients following autogenous osteochondral &apos;'plug'&apos; transfer. Three musculoskeletal radiologists retrospectively reviewed images to evaluate graft and donor site appearance and MR findings were correlated with clinical outcomes. Results: MR images demonstrated graft protuberance (n=12/21; range 1-2 mm), depression (n=2/21; range 1 mm), and surface incongruity: mild (n=17/21), moderate (n=2/21), marked (n=1/21). The T2 signal of graft cartilage was similar to that of adjacent cartilage in 25 of 29 examinations, and increased in four. Graft cartilage thickness relative to adjacent cartilage was <50% in six patients, 50-100% in 15. Graft enhancement in bone was absent at 2 weeks, but present at between 4 and 6 weeks following surgery. All patients had clinical follow-up examinations and knee outcome survey scores were obtained in 15 patients with follow-up greater than 3 months after surgery. All patients demonstrated the expected short-term progressive clinical improvement. Conclusion: MR images reveal a wide range of appearances following osteochondral &apos;'plug'&apos; transfer. Minor variations in graft orientation and surface congruity do not result in adverse clinical outcome in the short term. (orig.)

  7. Mineral and Elemental Composition Features of &apos;'Loose'&apos; Oolitic Ores in Bakchar Iron Ore Cluster (Tomsk Oblast)

    International Nuclear Information System (INIS)

    Geo-technological investigation considerations of iron ore deposits within the Bakchar ore cluster are being carried out. The mineral and elemental composition of &apos;'loose'&apos; ores have been studied, embracing such important aspects as the distribution pattern of valuable and harmful impurities, the determination of element concentrators (such as vanadium, phosphate and sulphur) in basic minerals and the analysis of ore composition varaiation in volume ore cluster. Based on investigation results the mineral and elemental composition characteristic features of &apos;'loose'&apos; ores were defined. Although hydrogoethite was the basic identified ore mineral, such minerals as goethite, lepidocrocite, leptochlorite, siderite and hisingerite were also found. The deportment of calcium phosphate (anapaite) and phosphates of rare-earth elements (monazite, killarite), which are associated with the harmful impurity- phosphorous, are described. It has been defined that the ore constituent composition contains such persistent impurities as vanadium and manganese, the content of which is 0.35% and 0.03%, respectively. The &apos;'loose'&apos; ores are continuous in mineral composition, both in area and cross-section throughout the Bakchar ore cluster. Based on the sample element composition analysis the most perspective areas for further mineral processing could be: western with the fraction of 1....0.2mm. and eastern- fraction of 1...0.1mm

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) examines the results obtained in practice concerning the use of the &apos;Minergie&apos; low energy consumption standard. Experience gained with &apos;Minergie&apos; refurbishment projects is reviewed and the critical points and constraints found are discussed. Further, recommendations for improvements in the use of the &apos;Minergie&apos; standard are made. The study is based on questions posed to building owners in the German speaking part of Switzerland who have carried out refurbishment projects to meet &apos;Minergie&apos; standards as well as questions posed to those who did not adhere to &apos;Minergie&apos; standards in the refurbishment of their buildings. The reasons quoted for using / not using the standard are listed and discussed. Possible tightening of energy regulations concerning renovation work are discussed. The recommendations resulting from the survey are also noted and discussed.

    The spectral characters of an acupuncture point named &apos;Waiqiu&apos; in superficial fascia tissue have been studied by photoluminescence (PL) spectroscopy under the excitation of 457.9 nm. The PL around &apos;Waiqiu&apos; acupuncture point consists of two sub-bands resulting from the flavin adenine dinucleotide (FAD) and phospholipids, and the porphyrins (including purine, isoxanthopterin and tryptophan), respectively. More emission due to FAD and phospholipids is found inside the acupuncture effect area of &apos;Waiqiu&apos; than its marginal or outside acupuncture regions. The ratio of emission intensity of FAD and phospholipids to one of porphyrins gradually decreases along the direction away from the center of the acupuncture point. It implies that the component proportion changes between FAD, phospholipids and porphyrins around the &apos;Waiqiu&apos; acupuncture point. We suggest that there might be a certain relationship between redox function of FAD and &apos;Waiqiu&apos; acupuncture effect.

    , very little information is available on apoE2 genotype. In the present study, we have characterized behavioral and learning phenotypes in young transgenic mice apoE2, apoE3 and apoE4 of both sexes. We have also determined the levels of brain-derived neurotrophic factor (BDNF) and its receptor TrkB in...... exploration of an open-field, which is compatible with a hyperactive behavior, was found in apoE2 females, while a decreased activity was observed in apoE4 mice. Increased BDNF levels in the frontal cortex were observed in apoE2 mice compared to apoE3. These results underscore behavioral differences between...

  11. Reduced hippocampal volume in healthy young ApoE4 carriers: an MRI study.

    Full Text Available The E4 allele of the ApoE gene has consistently been shown to be related to an increased risk of Alzheimer's disease (AD. The E4 allele is also associated with functional and structural grey matter (GM changes in healthy young, middle-aged and older subjects. Here, we assess volumes of deep grey matter structures of 22 healthy younger ApoE4 carriers and 22 non-carriers (20-38 years. Volumes of the nucleus accumbens, amygdala, caudate nucleus, hippocampus, pallidum, putamen, thalamus and brain stem were calculated by FMRIB's Integrated Registration and Segmentation Tool (FIRST algorithm. A significant drop in volume was found in the right hippocampus of ApoE4 carriers (ApoE4+ relative to non-carriers (ApoE4-, while there was a borderline significant decrease in the volume of the left hippocampus of ApoE4 carriers. The volumes of no other structures were found to be significantly affected by genotype. Atrophy has been found to be a sensitive marker of neurodegenerative changes, and our results show that within a healthy young population, the presence of the ApoE4+ carrier gene leads to volume reduction in a structure that is vitally important for memory formation. Our results suggest that the hippocampus may be particularly vulnerable to further degeneration in ApoE4 carriers as they enter middle and old age. Although volume reductions were noted bilaterally in the hippocampus, atrophy was more pronounced in the right hippocampus. This finding relates to previous work which has noted a compensatory increase in right hemisphere activity in ApoE4 carriers in response to preclinical declines in memory function. Possession of the ApoE4 allele may lead to greater predilection for right hemisphere atrophy even in healthy young subjects in their twenties.

    In 2004 the Matra plant management initiated a 60 M euro investment programme to increase the generating capacity of units 4 and 5 of the lignite fuelled plant and to give it greater flexibility. This has been achieved by adding a 30 MW natural gas-fired topping gas turbine to each of the 230 MW units, for commissioning by 2007. The power uprate meant the capacity of the dry-tower based cooling system was increased by 24 W for each unit. This has now undergone a major upgrade, involving addition of a wet cooling tower to create a &apos;hybrid&apos; system. It is one of the largest such projects ever carried out, and the first involving a dry-tower cooling system of the Heller type. The result is increased competitiveness and efficiency, with a 250,000 t reduction in annual carbon dioxide emissions. 3 figs.

    Objectives: Since the first description of rapid destruction of dental hard tissues following head and neck radiotherapy 80 years ago, &apos;radiation caries&apos; is an established clinical finding. The internationally accepted clinical evaluation score RTOG/EORTC however is lacking a classification of this frequent radiogenic alteration. Material and Methods: Medical records, data and images of radiation effects on the teeth of more than 1,500 patients, who underwent periradiotherapeutic care, were analyzed. Macroscopic alterations regarding the grade of late lesions of tooth crowns were used for a classification into 4 grades according to the RTOG/EORTC guidelines. Results: No early radiation effects were found by macroscopic inspection. In the first 90 days following radiotherapy 1/3 of the patients complained of reversible hypersensitivity, which may be related to a temporary hyperemia of the pulp. It was possible to classify radiation caries as a late radiation effect on a graded scale as known from RTOG/EORTC for other organ systems. This is a prerequisite for the integration of radiation caries into the international nomenclature of the RTOG/EORTC classification. Conclusions: The documentation of early radiation effects on dental hard tissues seems to be neglectable. On the other hand the documentation of late radiation effects has a high clinical impact. The identification of an initial lesion at the high-risk areas of the neck and incisal part of the tooth can lead to a successful therapy as a major prerequisite for orofacial rehabilitation. An internationally standardized documentation is a basis for the evaluation of the side effects of radiooncotic therapy as well as the effectiveness of protective and supportive procedures. (orig.)

    During the previous six annual sessions of the International Petroleum Environmental Conference (IPEC), little attention has been given to international issues. Although the US is clearly a leader in oil field research and regulatory development information is available on interesting projects throughout the world Many participants in IPEC have little exposure to international oil and gas environmental problems and solutions. Beginning with the 7th IPEC, a stronger effort is being made to include international issues in the confidence. This paper describes some of the author&apos;s experiences in working with international oil and gas environmental issues in North America, Latin America, Europe, and Asia. Among the topics to be discussed are the issues that developing oil and gas-producing nations face and the need for sensitivity to other nation&apos;s cultures and legal systems.

    This book contains the papers presented at the 7th Duesseldorf energy law conference on grid access regulation, in which renowned experts of the Bundesnetzagentur, science and industry take stock for the first time of grid access regulation and its effects on the power industry. The focus of the papers is on current court rulings which are viewed from different angles. The issues are discussed both from the view of legal science and from the view of the courts and the parties concerned. The &apos;pilot case&apos; of Vattenfall Europe Transmission GmbH vs. Bundesnetzagentur gets particular attention. A report on the experience with regulation management shows how legal specifications are reflected in the everyday work of grid operators. (orig.)

    The resin-in-pulp process is a technical variant of the recovery process of uranium in dilute solution by means of ion exchanger resins. An anion resin, XE 123, of a well-defined grain size is placed in direct contact with the pulp produced by sulfuric acid attack on ore with a low uranium content. This process is of particular value in the treatment of pulps that cannot be filtered or decanted, such as those obtained with ore from Brosses. The preparation of the pulp, the elution of the uranium, and its fixation, as well as the various factors encountered in these operations, are discussed.

    Mutations in Amyloid β Precursor Protein (APP) and in genes that regulate APP processing--such as PSEN1/2 and ITM2b/BRI2--cause familial dementia, such Familial Alzheimer disease (FAD), Familial Danish (FDD) and British (FBD) dementias. The ApoE gene is the major genetic risk factor for sporadic AD. Three major variants of ApoE exist in humans (ApoE2, ApoE3, and ApoE4), with the ApoE4 allele being strongly associated with AD. ITM2b/BRI2 is also a candidate regulatory node genes predicted to mediate the common patterns of gene expression shared by healthy ApoE4 carriers and late-onset AD patients not carrying ApoE4. This evidence provides a direct link between ITM2b/BRI2 and ApoE4. To test whether ApoE4 and pathogenic ITM2b/BRI2 interact to modulate learning and memory, we crossed a mouse carrying the ITM2b/BRI2 mutations that causes FDD knocked-in the endogenous mouse Itm2b/Bri2 gene (FDDKI mice) with human ApoE3 and ApoE4 targeted replacement mice. The resultant ApoE3, FDDKI/ApoE3, ApoE4, FDDKI/ApoE4 male mice were assessed longitudinally for learning and memory at 4, 6, 12, and 16-17 months of age. The results showed that ApoE4-carrying mice displayed spatial working/short-term memory deficits relative to ApoE3-carrying mice starting in early middle age, while long-term spatial memory of ApoE4 mice was not adversely affected even at 16-17 months, and that the FDD mutation impaired working/short-term spatial memory in ApoE3-carrying mice and produced impaired long-term spatial memory in ApoE4-carrying mice in middle age. The present results suggest that the FDD mutation may differentially affect learning and memory in ApoE4 carriers and non-carriers. PMID:26528887

    Cardiac magnetic resonance (CMR) has increasingly proved to be a valuable diagnostic tool for evaluating patients with suspected myocarditis. The objective of this study was to evaluate the diagnostic value of functional and morphological parameters including tissue characterization in patients with &apos;&apos;infarct-like myocarditis&apos;&apos;. 43 patients with clinically verified cases of &apos;&apos;infarct-like myocarditis&apos;&apos; (median time to MRI scanning after admission for acute symptoms 3 days) and 35 control patients matched by age and sex were included in this retrospective case control study. In this study we used a 1.5 T MRI scanner conducting steady-state-free-precession sequences, T2-weighted imaging, T1-weighted imaging before and after contrast administration and late gadolinium enhancement sequences. According to the recommendations for CMR diagnosis of myocarditis (Lake Louise consensus criteria), a scan was positive for acute myocarditis if 2 of 3 CMR criteria were present. 30 % of the patients with &apos;&apos;infarct-like myocarditis&apos;&apos; had a reduced left ventricular ejection fraction, 11 % had an increased LV end-diastolic volume index and 35 % had an increased LV mass index. The sensitivity of wall motion abnormalities was 63 % with a regional distribution in 49 %. In 47 % of cases regional wall motion abnormalities were present in the lateral left ventricular segments. Pericardial effusions were discovered in 65 % of cases with a circular appearance in 21 % and focal manifestation in 44 %.

    As is generally known, the governing parties CDU/CSU and FDP agreed a few weeks ago in the 17{sup th} legislative period of the German Bundestag in a rare show of unanimity, together with the parties SPD and Buendnis 90/Die Gruenen, as well as with the Laender, on a &apos;law to search and select a location for a permanent disposal site for heat-generating radioactive waste products and to change other laws&apos;, in brief a location selection act also called StandAG. The law was received with animated approval from the ranks of the parties - with the exception of the (left-wing) party Die Linke. This praise is a tad bewildering, since the Bundesumweltministerium (Federal Department of the Environment) named solving the task within a single generation as one of the principles for the StandAG, and it was emphasised again and again in the debates about the StandAG that the problem of permanent disposal must not be shifted to the next generation. Conclusion: - The StandAG leads to a postponement of solving the permanent disposal site issue by a least several generations with its predictable, long-winded selection method. - The decision not to explore Gorleben conclusively could lead to the site being permanently (&apos;wasted&apos; or) &apos;burned&apos;. - The de-central, interim disposal site Gorleben is likewise &apos;burned&apos; without having a resilient alternative solution for the glass coquilles that must be taken back. - The people&apos;s protest is exponentiated by the number of the potential sites for the StandAG. - The costs for the alternative site search will not be shifted to the producers of the waste that are obliged by law to deliver the waste because of the financial provisions of the constitution. - The third party protection dogma has not been broken up, which will at least lead to delays in the procedure and will have effects on other major projects in the long run.

    Effective utilization of information systems is an important point in business activities, e.g., for improvements of jobs and job efficiency. Fuji Electric has developed services to help establish systems for WWW application and groupware, aimed at information sharing and improved communication. They include services for consultation, and construction, operation and maintenance of the necessary systems. These services have the following major features. They include the consultation services, e.g., for planning environments required for introduction of the system and schedules for its introduction, and drawing standards for assessing the introduced system; basic designs for designing detailed configuration of the system to be introduced; starting up the system, e.g., system setting up and confirmation of smooth operation of the system; and question-and-answer cessions to support stable operation of the system. The company plans to start providing a platform, tentatively named &apos;Joint MEISTER/InfoTerrace,&apos; which will support information transmission by Web. (NEDO)

    Currently, there is no reliable method to differentiate acute from chronic carotid occlusion. We propose a novel CTA-based method to differentiate acute from chronic carotid occlusions that could potentially aid clinical management of patients. We examined 72 patients with 89 spontaneously occluded extracranial internal carotids with CT angiography (CTA). All occlusions were confirmed by another imaging modality and classified as acute (imaging <1 week of presumed occlusion) orchronic (imaging >4 weeks), based on circumstantial clinical and radiological evidence. A neuroradiologist and a neurologist blinded to clinical information determined the site of occlusion on axial sections of CTA. They also looked for (a) hypodensity in the carotid artery (thrombus), (b) contrast within the carotid wall (vasa vasorum), (c) the site of the occluded carotid, and (d) the &apos;&apos;carotid ring sign&apos;&apos; (defined as presence of a and/or b). Of 89 occluded carotids, 24 were excluded because of insufficient circumstantial evidence to determine timing of occlusion, 4 because of insufficient image quality, and 3 because of subacute timing of occlusion. Among the remaining 45 acute and 13 chronic occlusions, inter-rater agreement (kappa) for the site of proximal occlusion was 0.88, 0.45 for distal occlusion, 0.78 for luminal hypodensity, 0.82 for wall contrast, and 0.90 for carotid ring sign. The carotid ring sign had 88.9% sensitivity, 69.2% specificity, and 84.5% accuracy to diagnose acute occlusion. The carotid ring sign helps to differentiate acute from chronic carotid occlusion. If further confirmed, this information may be helpful in studying ischemic symptoms and selecting treatment strategies in patients with carotid occlusions. (orig.)

    Volatile organic compounds (VOCs) are suspected to contribute significantly to &apos;&apos;Sick Building Syndrome&apos;&apos; (SBS), a complex of subchronic symptoms that occurs during and in general decreases away from occupancy of the building in question. A new approach takes into account individual VOC potencies, as well as the highly correlated nature of the complex VOC mixtures found indoors. The new VOC metrics are statistically significant predictors of symptom outcomes from the California Healthy Buildings Study data. Multivariate logistic regression analyses were used to test the hypothesis that a summary measure of the VOC mixture, other risk factors, and covariates for each worker will lead to better prediction of symptom outcome. VOC metrics based on animal irritancy measures and principal component analysis had the most influence in the prediction of eye, dermal, and nasal symptoms. After adjustment, a water-based paints and solvents source was found to be associated with dermal and eye irritation. The more typical VOC exposure metrics used in prior analyses were not useful in symptom prediction in the adjusted model (total VOC (TVOC), or sum of individually identified VOCs ({Sigma}VOC{sub i})). Also not useful were three other VOC metrics that took into account potency, but did not adjust for the highly correlated nature of the data set, or the presence of VOCs that were not measured. High TVOC values (2--7 mg m{sup {minus}3}) due to the presence of liquid-process photocopiers observed in several study spaces significantly influenced symptoms. Analyses without the high TVOC values reduced, but did not eliminate the ability of the VOC exposure metric based on irritancy and principal component analysis to explain symptom outcome.

  8. Effect of apoA-I on cholesterol release and apoE secretion in human mature adipocytes

    Full Text Available Abstract Background The risk of cardiovascular disease is inversely correlated to level of plasma HDL-c. Moreover, reverse cholesterol transport (RCT from peripheral tissues to the liver is the most widely accepted mechanism linked to the anti-atherosclerotic activity of HDL. The apolipoprotein A-I (apoA-I and the ABC transporters play a key role in this process. Adipose tissue constitutes the body's largest pool of free cholesterol. The adipose cell could therefore be regarded as a key factor in cholesterol homeostasis. The present study investigates the capacity of primary cultures of mature human adipocytes to release cholesterol and explores the relationships between apoA-I, ABCA1, and apoE as well as the signaling pathways that could be potentially involved. Results We demonstrate that apoA-I induces a strong increase in cholesterol release and apoE secretion from adipocytes, whereas it has no transcriptional effect on ABCA1 or apoE genes. Furthermore, brefeldin A (BFA, an intracellular trafficking inhibitor, reduces basal cholesterol and apoE secretion, but does not modify induction by apoA-I. The use of statins also demonstrates that apoA-I stimulated cholesterol release is independent of HMG-CoA reductase activation. Conclusion Our work highlights the fact that adipose tissue, and particularly adipocytes, may largely contribute to RCT via a mechanism specifically regulated within these cells. This further supports the argument that adipose tissue must be regarded as a major factor in the development of cardiovascular diseases, in particular atherosclerosis.

  9. A neural model for transient identification in dynamic processes with &apos;don&apos;t know&apos; response

    This work presents an approach for neural network based transient identification which allows either dynamic identification or a &apos;don&apos;t know&apos; response. The approach uses two &apos;jump&apos; multilayer neural networks (NN) trained with the backpropagation algorithm. The &apos;jump&apos; network is used because it is useful to dealing with very complex patterns, which is the case of the space of the state variables during some abnormal events. The first one is responsible for the dynamic identification. This NN uses, as input, a short set (in a moving time window) of recent measurements of each variable avoiding the necessity of using starting events. The other one is used to validate the instantaneous identification (from the first net) through the validation of each variable. This net is responsible for allowing the system to provide a &apos;don&apos;t know&apos; response. In order to validate the method, a Nuclear Power Plant (NPP) transient identification problem comprising 15 postulated accidents, simulated for a pressurized water reactor (PWR), was proposed in the validation process it has been considered noisy data in order to evaluate the method robustness. Obtained results reveal the ability of the method in dealing with both dynamic identification of transients and correct &apos;don&apos;t know&apos; response. Another important point studied in this work is that the system has shown to be independent of a trigger signal which indicates the beginning of the transient, thus making it robust in relation to this limitation.

    The response of a variety of W material grades to nanostructure &apos;fuzz&apos; formation is explored. W targets are exposed to He or D{sub 2}-0.2He plasmas in PISCES-B at 900-1320 K to below sputter threshold He{sup +} ions of energy 25-60 eV for up to 2.2 x 10{sup 4} s. SEM and XPS reveal nanoscopic reorganization of the W surface to a layer of &apos;fuzz&apos; of porosity {approx}90% as determined by a &apos;fuzz&apos; removal/weight loss method. The variability of &apos;fuzz&apos; growth is examined at 1120 K for 1 h durations: SR, SC and doped W grades - La{sub 2}O{sub 3} (1% wt.), Re (5% and 10% wt.), and TiC (1.5% wt.) developed 2-3 {mu}m thick &apos;fuzz&apos; layers, while a VPS grade developed a layer 4 {mu}m thick. An RC grade revealed additional &apos;fuzz&apos; at deep (>100 {mu}m) grain boundaries. However, heat treatment up to 1900 K produced reintegration of &apos;fuzz&apos; with the bulk and He release at {approx}1000 K and {approx}1400-1800 K due to depopulation from vacancy complexes.

    2010-02-05

    The enormous amount of data collected by the B factories as well as the perspective concerning the upcoming experiments at the LHC provide us with the opportunity to perform high precision tests of the standard model. This dissertation presents two model independent precision tests of the weak sector of the standard model using extensions of the weak currents which are set up using effective field theory methods in order to control the size of the different contributions. Constraints on the coefficients of the terms can then be obtained by comparison with experimental results. The first analysis incorporates a test of the lefthandedness of the weak interaction in the quark sector. By introducing additional weak couplings the differential and total decay rates of the inclusive semileptonic decay anti B {yields} X{sub c}l anti {nu}{sub l} are calculated. The calculation includes the computation of the heavy-quark expansion which describes the interaction of the decaying b quark with respect to the background field of the B meson, up to order 1/m{sub b}{sup 4}. This has been done in a new, systematic way which does not involve the calculation of gluon matrix elements. Furthermore, radiative corrections have been included up to order O({alpha}{sub s}) including renormalization group running. The second part deals with the introduction of lepton flavor violating operators in the context of leptonic {tau} decays. These operators give rise to the effective four-fermion vertex {tau}{yields}ll{sup &apos;}l'&apos; as well as the subsequent radiative decay {tau}{yields}l{gamma}{sup *}{yields}ll{sup &apos;+}l{sup &apos;-}. The resulting Dalitz distributions turn out to predict completely different signatures for the radiative and the effective four-fermion vertices and provide the opportunity to check, whether the decay is induced either by a radiative or by an effective four-fermion vertex. Since different models which contain lepton flavor violation are normally more

    The aim of this study is to exploit the normal nature of peroneal nerve anatomy to identify constant magnetic resonance imaging (MRI) patterns in peroneal intraneural ganglia. This study is designed as a retrospective clinical study. MR images of 25 patients with peroneal intraneural ganglia were analyzed and were compared to those of 25 patients with extraneural ganglia and 25 individuals with normal knees. All specimens were interpreted as left-sided. Using conventional axial images, the position of the common peroneal nerve and either intraneural or extraneural cyst was determined relative to the proximal fibula and the superior tibiofibular joint using a symbolic clock face. In all patients, the common peroneal nerve could be seen between the 4 and 5 o&apos;clock position at the mid-portion of the fibular head. In patients with intraneural ganglia, a single axial image could reproducibly and reliably demonstrate both cyst within the common peroneal nerve at the mid-portion of the fibular head (signet ring sign) between 4 and 5 o&apos;clock and within the articular branch at the superior tibiofibular joint connection (tail sign) between 11 and 12 o&apos;clock; in addition, cyst within the transverse limb of the articular branch (transverse limb sign) was seen at the mid-portion of the fibular neck between the 12 and 2 o&apos;clock positions on serial images. Extraneural ganglia typically arose from more superior joint connections with the epicenter of the cyst varying around the entire clock face without a consistent pattern. There was no significant difference between the visual and template assessment of clock face position for all three groups (intraneural, extraneural, and controls). We believe that the normal anatomic and pathologic relationships of the common peroneal nerve in the vicinity of the fibular neck/head region can be established readily and reliably on single axial images. This technique can provide radiologists and surgeons with rapid and

    The problem of an electron in a quantum well is treated using the new (&apos;mirror&apos;) boundary conditions implying that the particle has a specular reflection from the well&apos;s boundaries. Solutions of the Schroedinger equation are obtained for some particular well&apos;s geometries when the variable separation method is applicable. The resemblance between the &apos;mirror&apos; and periodic boundary conditions is discussed. Comparison of the results with some experimental data shows that this approach can provide a reasonably accurate (without any adjustable parameters) description of nanosystems, including those with non-traditional geometry.

    We present new observations of the faint &apos;'Sirius-like'&apos; companion discovered to orbit HD 114174. Previous attempts to image HD 114174 B at mid-infrared wavelengths using NIRC2 at Keck have resulted in a non-detection. Our new L&apos;-band observations taken with the Large Binocular Telescope and L/M-band InfraRed Camera recover the companion (ΔL = 10.15 ± 0.15 mag, ρ = 0.&apos;&apos;675 ± 0.&apos;&apos;016) with a high signal-to-noise ratio (10σ). This measurement represents the deepest L&apos; high-contrast imaging detection at subarcsecond separations to date, including extrasolar planets. We confirm that HD 114174 B has near-infrared colors consistent with the interpretation of a cool white dwarf (WD; J – L&apos; = 0.76 ± 0.19 mag, K – L&apos; = 0.64 ± 0.20). New model fits to the object&apos;s spectral energy distribution indicate a temperature T {sub eff} = 4260 ± 360 K, surface gravity log g = 7.94 ± 0.03, a cooling age t{sub c} ≈ 7.8 Gyr, and mass M = 0.54 ± 0.01 M {sub ☉}. We find that the cooling ages given by theoretical atmospheric models do not agree with the age of HD 114174 A derived from both isochronological and gyrochronological analyses. We speculate on possible scenarios to explain the apparent age discrepancy between the primary and secondary. HD 114174 B is a nearby benchmark WD that will ultimately enable a dynamical mass estimate through continued Doppler and astrometric monitoring. Efforts to characterize its physical properties in detail will test theoretical atmospheric models and improve our understanding of WD evolution, cooling, and progenitor masses.

No grupo C45, o tempo de oclusão aórtica foi de 45 min (n = 7; no grupo PI45, os cães foram submetidos ao PI antes do pinçamento aórtico por 45 min (n = 7. No grupo C60, os cães foram submetidos a 60 min de oclusão aórtica (n = 7 e no grupo PI60, os cães foram submetidos ao PI, seguido pelo pinçamento aórtico por 60 min. Os ciclos de PI foram determinados pelas alterações dos PESS. RESULTADOS: Os índices de Tarlov dos grupos pré-condicionados foram significativamente melhores que os dos grupos de controle (p = 0,005. Observou-se paraplegia em três cães do C45 e em seis do C60, enquanto todos os cães do PI45 permaneceram neurologicamente normais, assim como quatro do grupo PI60. Houve correlação entre o tempo de recuperação dos PESS após a reperfusão aórtica e o estado neurológico pós-operatório (p = 0,011, com sensibilidade e especificidade de 0,75 e 0,83, respectivamente. CONCLUSÃO: O PI agudo repetitivo, baseado na monitorização do PESS, induziu proteção à isquemia medular causada pelo pinçamento aórtico prolongado. A monitorização do PESS parece ser um bom método de detecção precoce do comprometimento isquêmico medular.OBJECTIVES: To evaluate the effectiveness of acute ischemic preconditioning (IP, based on somatosensory evoked potentials (SSEP monitoring, as a method of spinal cord protection and to asses SSEP importance in spinal cord neuromonitoring.

  12. Safety requirements expected to the prototype fast breeder reactor &apos;Monju&apos;

    International Nuclear Information System (INIS)

    In July 2013, Nuclear Regulation Authority (NRA) has enforced new regulatory requirements in consideration of severe accidents for the commercial light water reactors (LWR) and also prototype power generation reactors such as the sodium-cooled fast reactors (SFR) of &apos;Monju&apos; based on TEPCO Fukushima Daiichi nuclear power plant accident (hereinafter referred to as &apos;1F accident&apos;) occurred in March 2011. Although the regulatory requirements for SFR will be revised by NRA with consideration for public comments, Japan Atomic Energy Agency (JAEA) set up &apos;Advisory Committee on Monju Safety Requirements&apos; consisting of fast breeder reactor (FBR) and safety assessment experts in order to establish original safety requirements expected to the prototype FBR &apos;Monju&apos; considering severe accidents with knowledge from JAEA as well as scientific and technical insights from the experts. This report summarizes the safety requirements expected to Monju discussed by the committee. (author)

    The present paper reports results of the VDE / ITG focus group &apos;&apos;Energy Information Networks and Systems&apos;&apos; that published its second position paper in autumn 2012. The focus was on the issue of distribution automation, since the successful implementation of a smart energy system can be achieved only on the basis of a profound automation of distribution networks and other systems of energy supply interacting with them. With the participation of experts from the fields of energy supply, telecommunications, IT and automation technology, various aspects of distribution automation in the context of smart grid were analyzed and appropriate recommendations derived. The results are summarized in Part A &apos;&apos;Distribution Automation in Smart Grid&apos;&apos; of the position paper. (orig.)

  14. How to distinguish a molecule from an &apos;elementary&apos; particle?

    International Nuclear Information System (INIS)

    We discuss how to use Morgan&apos;s pole counting rule to distinguish a molecular state from an &apos;elementary&apos; particle. As two examples we focus on X(3872) and f0(980) particles. A molecule may be generated from a meson loop bubble chain, and an &apos;elementary&apos; particle is related to an explicit interaction field in the effective Lagrangian and propagates with a Breit–Wigner propagator. For X(3872) it is found that the data favor the &apos;elementary&apos; particle explanation. For f0(980) the study becomes much more difficult, since highly nonperturbative dynamics is involved. A unitarization model analysis suggests that f0(980)&apos;s property is quite exotic. Unlike other light scalars, it does not behave like a q¯q state, and could be interpreted as a molecule.

    Funded by the Environment Ministry of the federal state of Baden-Wuerttemberg, ZSW has developed a {mu}-CHP PEM fuel cell system for domestic energy supply in the 4-kW{sub e} class (&apos;'bw-cell'&apos;). The net electric efficiency is above 30% at loads from 50 to 100%. Without principal design modifications, up to 35% efficiency can be realised by optimisation of the auxiliary components and the inverter. The &apos;'bw-cell'&apos; weight of 200 kg with a refrigerator volume reveals the potential for future series production. Next development steps comprise the refitting to fossile/regenerative energy carriers like LPG (liquefied petroleum gas), ethanol, methanol and DME (dimethyl ether). (orig.)

    2010-07-01

    The author of the contribution under consideration focuses on China&apos;s economic and strategic interests in the Caspian Crescent and the means by which the Peoples Republic of China seeks to enforce them. Most analysts, researches and Chinese officials rank the issue of the region&apos;s hydrocarbon resources equal to or even below other issues of interest such as border issues, regional stability and terrorism. But the facts previously stated raise questions about the particular role of energy in the overall context of China&apos;s interests in that region as well as the significance of Sino-Iranian relations for Beijing&apos;s regional goals. These goals give particular consideration to the Chinese government&apos;s blunt commitment to its ties with Pariah Indian despite pressure and criticism from the USA. Thereon, this study features three research objectives: (1) To outline China&apos;s economic and strategic interests in the Caspian Crescent and demonstrate they are dominated by Beijing&apos;s fundamental interest in oil and gas; (2) To demonstrate that Iran is China&apos;s key partner in the whole region around the Caspian Sea for the accomplishment of its interests in hydrocarbons and regional preponderance.

  18. Deletion of L-selectin increases atherosclerosis development in ApoE-/- mice.

    Directory of Open Access Journals (Sweden)

    Izabela Rozenberg

    Full Text Available Atherosclerosis is an inflammatory disease characterized by accumulation of leukocytes in the arterial intima. Members of the selectin family of adhesion molecules are important mediators of leukocyte extravasation. However, it is unclear whether L-selectin (L-sel is involved in the pathogenesis of atherosclerosis. In the present study, mice deficient in L-selectin (L-sel(-/- animals were crossed with mice lacking Apolipoprotein E (ApoE(-/-. The development of atherosclerosis was analyzed in double-knockout ApoE/L-sel (ApoE(-/-L-sel(-/- mice and the corresponding ApoE(-/- controls fed either a normal or a high cholesterol diet (HCD. After 6 weeks of HCD, aortic lesions were increased two-fold in ApoE(-/-L-sel(-/- mice as compared to ApoE(-/- controls (2.46%±0.54% vs 1.28%±0.24% of total aortic area; p<0.05. Formation of atherosclerotic lesions was also enhanced in 6-month-old ApoE(-/-L-sel(-/- animals fed a normal diet (10.45%±2.58% vs 1.87%±0.37%; p<0.05. In contrast, after 12 weeks of HCD, there was no difference in atheroma formation between ApoE(-/-L-sel(-/- and ApoE(-/- mice. Serum cholesterol levels remained unchanged by L-sel deletion. Atherosclerotic plaques did not exhibit any differences in cellular composition assessed by immunohistochemistry for CD68, CD3, CD4, and CD8 in ApoE(-/-L-sel(-/- as compared to ApoE(-/- mice. Leukocyte rolling on lesions in the aorta was similar in ApoE(-/-L-sel(-/- and ApoE(-/- animals. ApoE(-/-L-sel(-/- mice exhibited reduced size and cellularity of peripheral lymph nodes, increased size of spleen, and increased number of peripheral lymphocytes as compared to ApoE(-/- controls. These data indicate that L-sel does not promote atherosclerotic lesion formation and suggest that it rather protects from early atherosclerosis.

    The program deck MODIS (&apos;&apos;Moment DIstrubution&apos;&apos;) is designed to be used as operational tool for modelling the dispersion of a point source under general atmospheric conditions. The concentration distribution is determined by calculating its cross-wind moments on a vertical grid oriented in the main wind direction. The model contains a parametrization for horizontal and vertical diffusion coefficients based on a second order closure model. The Eulerian time scales, preliminarily determined by fitting measured plume cross sections, are confirmed by comparison with data from the EPRI plume model validation project. 8 refs., 9 figs.

    &apos;&apos;Saunaparadies Erding&apos;&apos; is a sauna spa with 16 newly constructed saunas and with an uncommon heating concept. The investor opted for hot air instead of electric heating. Accordingly, an industrial-scale boiler was installed in the mechanical equipment room. The boiler supplies air of 170 degC to the air-to-water heat exchangers in the sauna cabins. The design of this system was a great challenge to the planners and constructors and also to the components of the piping system. (orig.)

    Factors determining who develops PTSD following trauma are not well understood. The €4 allele of the apolipoprotein E (apoE) gene is associated with dementia and unfavorable outcome following brain insult. PTSD is also associated with dementia. Given evidence that psychological trauma adversely affects the brain, we hypothesized that the apoE genotype moderates effects of psychological trauma on PTSD pathogenesis. To investigate the moderation of the relationship between PTSD symptoms and com...

    This thesis work is about the validation of the new criticality-safety package CRISTAL and contributes to the modernization and the improvement of the computational tools. The first part presents neutronic elements, the objectives of safety criticality studies and the package CRISTAL. Then, the validation work concerned two series of experiments involving uranyl solutions (UO{sub 2}F{sub 2}) and UO{sub 2} powders. For these experiments, the differences between the computation results and the experimental results were analysed. It was highlighted interesting physical phenomena such of the compensations of errors between the approximate representation by the 99 energy group structure on the first resonance of oxygen and the anisotropy of the diffusion simulation as well as the influence of uranium 234 in high enriched solutions in uranium 235. Once the work of the experimental qualification carried out, raises the question of the use the base of qualification and the &apos;'calculation-experiment'&apos; variations which are referred to it. It is often difficult to establish the link between the &apos;&apos;studied configuration&apos;&apos; and the experiments of the base of qualification. The presented characterisation system proposes to answer in a way automatic and quantified this difficulty: - in bringing an answer on the package qualification for the studied configuration, - in giving an estimate of the package bias. To answer these points, it was defined a set of 35 characteristic neutronic parameters representing the behaviour of the medium. To process the information brought by these parameters and to use it to answer the objectives of the system, we called upon statistical methods (Principal Components Analysis and Sliced Inverse Regression). The results obtained in the feasibility studies showed the relevance of these methods for the considered objectives. (author)

    We measured the volatile chemical composition of comet C/2007 N3 (Lulin) on three dates from 2009 January 30 to February 1 using NIRSPEC, the high-resolution ({lambda}/{Delta}{lambda} Almost-Equal-To 25,000), long-slit echelle spectrograph at Keck 2. We sampled nine primary (parent) volatile species (H{sub 2}O, C{sub 2}H{sub 6}, CH{sub 3}OH, H{sub 2}CO, CH{sub 4}, HCN, C{sub 2}H{sub 2}, NH{sub 3}, CO) and two product species (OH* and NH{sub 2}). We also report upper limits for HDO and CH{sub 3}D. C/2007 N3 (Lulin) displayed an unusual composition when compared to other comets. Based on comets measured to date, CH{sub 4} and C{sub 2}H{sub 6} exhibited &apos;normal&apos; abundances relative to water, CO and HCN were only moderately depleted, C{sub 2}H{sub 2} and H{sub 2}CO were more severely depleted, and CH{sub 3}OH was significantly enriched. Comet C/2007 N3 (Lulin) is another important and unusual addition to the growing population of comets with measured parent volatile compositions, illustrating that these studies have not yet reached the level where new observations simply add another sample to a population with well-established statistics.

    1994-06-01

    Biodegradable loose fill packing material &apos;ECO-FOAM&apos; was developed to prevent pollution of the natural environment after plastics have been used. The material uses a hybrid cornstarch of 95% or higher and a small amount of water-soluble synthetic additive(polyvinyl alcohol). The manufacturing method is patented by National And Chemical Corporation in the U.S.A. The material has nearly the same buffering performance as the conventional foaming polystyrene, can be used on the existing filling facilities, and is non-electrically chargeable. Its raw material causes no destruction of resources and forests as experienced in petroleum and lumbers, and requires no foaming material such as butane for swelling, but foams naturally by mechanical action and heat of an extruding machine. The material has biodegradability of full degradation type, and is friendly with the environment. It is non-poisoning and safe, but has some problem in water resistance. While the material may be treated in various ways after having been disposed of as refuse, it may be incinerated, filled, or utilized as compost. The material may be degraded by activated sludge generated from sewage treatment. 5 figs.

    Households&apos; recycling effort is often argued to be of an insignificant size. It is also frequently argued that this contribution, if significant, is not a cost to households, since it is voluntary. Thus households&apos; use of time and energy are frequently disregarded in cost-benefit analyses of stricter recycling targets. In this survey, based on 1162 interviews, we find that sorting at source involves significant extra use of time and energy in the households. On average, each of those asked reported that they use close to half an hour a week for cleaning, sorting and transporting recyclable waste. On average, 185 h is used per tonne of waste. Four out of ten reported that they use warm or hot water to clean the materials. When investigating the motives for sorting waste, we find that many perceive sorting as mandatory, while some in fact find it a pleasant activity in itself. Moral motives for sorting at source are also widespread. A majority would prefer that a company took over the sorting if this were possible, and on average, the respondents are willing to pay US$ 20/year for this service.

    In 2001, a diverse group of citizens ranging from conservationists to industrial developers joined forces to produce a factual description of Oak Ridge&apos;s environment and the issues associated with contamination on the U.S. Department of Energy (DOE) reservation. This consensus effort was a result of common values not generally seen in this spectrum of philosophies, and of shared concerns about rising property taxes, declining city services, fleeing retail establishments, and diminishing real estate values. These problems are attributed to waning local DOE budgets coupled with Oak Ridge&apos;s national reputation of being contaminated and unsafe. This undeserved reputation harms the city&apos;s ability to attract new industry to replace declining federal employment and to induce families to live in the community. Representatives from a spectrum of conservation, environmental, economic development, local government, and civic organizations were invited to meet regarding how to best explain the complex environmental story of Oak Ridge and the DOE reservation. This large group decided to publish a straightforward explanation of the environmental quality of the city and its relationship to the DOE reservation in easy-to-understand language. The result was Oak Ridge, Tennessee--A Citizen&apos;s Guide to the Environment, a 28-page glossy booklet, distributed through the Chamber of Commerce and other organizations. The Oak Ridger ensured wide distribution in the community by publishing it as an insert in the daily paper. The material is also available on several web sites. A trifold brochure summarizing and promoting the larger document was also produced for wider distribution. The integrity of the Citizen&apos;s Guide was ensured by having a six-member editorial team manage writing and review of the document. There was no direct involvement by the DOE and its contractor. Knowledgeable citizen writers from throughout the community contributed technical and descriptive

    This report summarises SKI&apos;s and SSI&apos;s joint review of the Swedish Nuclear Fuel and Waste Management Co&apos;s (SKB) safety report SR-Can (SKB TR-06-09). SR-Can is the first assessment of post-closure safety for a KBS-3 spent nuclear fuel repository at the candidate sites Forsmark and Laxemar, respectively. The analysis builds on data from the initial stage of SKB&apos;s surface-based site investigations and on data from full-scale manufacturing and testing of buffer and copper canisters. SR-Can can be regarded as a preliminary version of the safety report that will be required in connection with SKB&apos;s planned licence application for a final repository in late 2009. The main purpose of the authorities&apos; review is to provide feedback to SKB on their safety reporting as part of the pre-licensing consultation process. However, SR-Can is not part of the formal licensing process. In support of the authorities&apos; review three international peer review teams were set up to make independent reviews of SR-Can from three perspectives, namely integration of site data, representation of the engineered barriers and safety assessment methodology, respectively. Further, several external experts and consultants have been engaged to review detailed technical and scientific issues in SR-Can. The municipalities of Oesthammar and Oskarshamn where SKB is conducting site investigations, as well NGOs involved in SKB&apos;s programme, have been invited to provide their views on SR-Can as input to the authorities&apos; review. Finally, the authorities themselves, and with the help of consultants, have used independent models to reproduce part of SKB&apos;s calculations and to make complementary calculations. All supporting review documents are published in SKI&apos;s and SSI&apos;s report series. The main findings of the review are: -SKB&apos;s safety assessment methodology is overall in accordance with applicable regulations, but part of the methodology needs to be

    The present project, whose abbreviated name is RENOX, has the aim of reducing NO{sub x} emissions from the combustion of hard coals or coals with low volatile matter contents. It is applied to the combustion of these coals in arc boilers (or &apos;'U'&apos; boilers), where the necessary combination of long presence times and high hearth temperatures facilitates the high NO{sub x} levels reached. The intended reduction in emissions is approached through the application of primary combustion measures, also known as adjustment or refining of combustion. This solution is adopted for two reasons: due to its efficiency in environmental and economic terms, and because it is an unavoidable step if the levels to be attained require the installation of specific gas crubbing systems (secondary measures). The practical nature of RENOX has led to the development of the project in two phases, corresponding to two logical stages: phase 1, associated with the RNA project, on the characterization of emissions and combustion, complex numeric modelling of flows inside the boiler, and determination of the viability and scope of the optimization of emissions, and phase 2, the OPTINOXproject, which follows the methodology and lessons of the first phase and, as a natural continuation of this, deals with the design, development, manufacturing and validation of a computerized system that processes real time data on the boiler where it is installed to monitor, supervise and control the commercial operation of the plant, optimizing its combustion efficiency and/or NO{sub x} emissions. The practical objective of this project is represented by the construction of a validated prototype to demonstrate the OPTINOX system, which is capable of determining operating and control strategies that can minimize NO{sub x} emissions without unfavourably affecting the productivity and specific consumption of the units. Phase 1 development activities took place in groups 3, 4 and 5 of Compostilla

  3. Japan&apos;s new energy policy

    International Nuclear Information System (INIS)

    Japan&apos;s energy policy is undergoing fundamental changes. The accident at TEPCO&apos;s Fukushima Daiichi nuclear power plant questions the future contribution of nuclear power in the national energy mix. Growing imports of fossil fuels to replace the lost nuclear capacity inflated energy prices and raise economic and energy security challenges. At the same time, the US shale gas and oil revolution is reshaping the global energy scene. Japan expects to take advantage of the trend to eliminate the &apos;Asian premium&apos; on natural gas prices and expand cheaper natural gas consumption. These developments have driven the Government of Japan to review its energy policy from scratch and adopt a new Strategic Energy Plan. This new policy has far reaching implications for gas and coal development in Japan but also for the international markets as Japan is the world&apos;s largest LNG importer and the second largest coal importer. This document summarizes the key findings of a new report by CEDIGAZ &apos;Japan&apos;s new energy policy: In search for stable and competitive energy supply&apos;. The report analyzes the current changes taking place on the gas and coal markets in Japan, in light of the new energy policy adopted in April 2014, and in particular the decision to restart safe nuclear power plants and push forward electricity market reforms

    OAK (B204) Final Report, NERI Project: &apos;&apos;An Innovative Reactor Analysis Methodology Based on a Quasidiffusion Nodal Core Model&apos;&apos; The present generation of reactor analysis methods uses few-group nodal diffusion approximations to calculate full-core eigenvalues and power distributions. The cross sections, diffusion coefficients, and discontinuity factors (collectively called &apos;&apos;group constants&apos;&apos;) in the nodal diffusion equations are parameterized as functions of many variables, ranging from the obvious (temperature, boron concentration, etc.) to the more obscure (spectral index, moderator temperature history, etc.). These group constants, and their variations as functions of the many variables, are calculated by assembly-level transport codes. The current methodology has two main weaknesses that this project addressed. The first weakness is the diffusion approximation in the full-core calculation; this can be significantly inaccurate at interfaces between different assemblies. This project used the nodal diffusion framework to implement nodal quasidiffusion equations, which can capture transport effects to an arbitrary degree of accuracy. The second weakness is in the parameterization of the group constants; current models do not always perform well, especially at interfaces between unlike assemblies. The project developed a theoretical foundation for parameterization and homogenization models and used that theory to devise improved models. The new models were extended to tabulate information that the nodal quasidiffusion equations can use to capture transport effects in full-core calculations.

  8. Steady-State Confinement of Non-Neutral Plasmas Using Trivelpiece-Gould Modes Excited by a &apos;&apos;Rotating Wall&apos;&apos;

    A &apos;&apos;rotating wall&apos;&apos; voltage varying as exp(im{sub {theta}}{theta}+ ik{sub z}z - i2{pi}ft) can give steady-state confinement of more than 10{sup 9} charges in a Penning-Malmberg trap at 4 Tesla. For both pure ion plasmas and pure electron plasmas, the torque exerted on the plasma by the rotating wall exhibits peaks at the frequencies of k{sub z} {ne} 0 Trivelpiece-Gould modes. As expected, modes with f > m{sub {theta}}fr (i.e. propagating faster than the plasma rotation) give positive torque and cause plasma compression; and modes with f < m{sub {theta}}fr give adverse torque and cause plasma expansion. The rotating wall drive also causes plasma heating, but cyclotron radiation (in the electron case) and collisions with background residual neutral gas (in the ion case) keep the temperature low enough that background ionization is negligible. The rotating wall &apos;'slip'&apos; is typically greater for electrons than for ions, because f - m{sub {theta}}fr is proportional to the plasma frequency {omega}{sub p}. This contrasts with the k{sub z} = 0 rotating wall perturbation which couples to crystallized ion plasmas with no slip. By increasing the frequency of the rotating wall, we observed a plasma central density compression of about a factor of 20. These techniques may be useful for a variety of trapping experiments.

    Goedel emphasised philosophy as an important tool in science. Much less is known about his religious background. We should bear in mind that our evaluational perspective differs very much from the one in which Goedel lived. He was personally sure that there must be another existence after death-an afterlife (&apos;of unlimited life span&apos;). As a &apos;Baptized Lutheran&apos; he did not include &apos;Trinity&apos; in his creed. He was also certain that mind is separate from matter. This text tries to include Libet&apos;s &apos;readiness potential&apos; into the debate concerning the specificity of the mind. Neither Goedel&apos;s identification of materialism with mechanism nor his vision of the &apos;spirit&apos; are a viable solution of the problem.

  15. European Union&apos;s environmental strategy

    International Nuclear Information System (INIS)

    Environmental policy is an art of execution. Hence the fact that European Union member states have recently managed to agree on targets of emissions to fight climate change leaves open the question of how they will meet them. Economics cannot but embrace the scientific consensus on climate change and cannot say much about the efficiency of alternative technologies. Yet, its expertise is valuable to calculate economic effects and fairness of policies and to assess the relevance of incentives structures and effectiveness of institutions put into place to convert scientific consensus into action. This article is concerned with this latter point: does the EU have the right institutions to fight climate change? We claim that such is not the case, and offer to institute a &apos;European Community of Environment, Energy and Research&apos; to go forward.

    Under certain experimental conditions the internal friction in metals can first increase and following prolonged irradiation decrease. Many models have been proposed to account for this &apos;&apos;peaking effect&apos;&apos;; however, in many of the cases, no effort is made to distinguish between the influence of interstitials and/or vacancies. To determine the nature of the point defect responsible for the peaking effect in high purity copper, we have performed a series of pulsed irradiations using neutrons and electrons. In all of the experiments an initial very rapid rise in the internal friction and Young&apos;s modulus was observed. These data show that a fast diffusing defect is responsible for the peaking effect: i.e. the interstitial.

    The concept of &apos;food miles&apos; presents an argument to buy goods which have travelled the shortest distance from farm to table, and to discriminate against long-haul transportation, especially air-freighted goods. The long-distance transport of food is associated with additional emissions due to increased transportation coupled with greater packaging, as well as a disconnection between the public and local farming. Furthermore, &apos;food miles&apos; encapsulates (and is at the vanguard of) the climate change debate in the UK. In light of growing international concern over the speed and scale of climate change, the concept of &apos;food miles&apos; has captured public attention and apparently is changing some consumers&apos; behaviour, although only around one-third of shoppers know of the concept.

    Allowable instantaneous minimum river flows are established in the Columbia and Snake Rivers to ensure safe passage of anadromous fish during their migration to the spawning grounds. However, water storage during periods of low power demands (at night and on weekends) would be beneficial to the power producers. This storage procedure is called &apos;'zero'&apos; river flow and is now permitted on a limited basis when there are few if any actively migrating anadromous fish present in the river system. Requests were made to extend &apos;'zero'&apos; river flow into periods when anadromous fish were actively migrating and a study was initiated. Radio-tracking studies were conducted on the Snake River between Lower Monumental and Little Goose Dams to determine the effect of &apos;'zero'&apos; river flow on the migration of adult chinook salmon, Oncorhynchus tshawytscha, and steelhead, Salmo gairdneri. From July through September, 1981, a total of 258 steelhead and 32 chinook salmon were radio-tagged. The rate of migration was used to determine differences between test and control fish and a gamma distribution model was used to describe the migration rate for radio-tagged fish. Estimates of the parameters of the model were used to statistically compare &apos;'zero'&apos; flow and normal river flow conditions for the radio-tagged fish. The results show that the &apos;'zero'&apos; flow condition delays the migration of adult chinook salmon and steelhead; therefore, extended periods of &apos;'zero'&apos; flow to store water are not recommended when fish are actively migrating in the river system. 16 refs., 5 figs., 9 tabs.

    Politics of course has more than its fair share of those who know everything and do their best not to let get the facts get in the way where inconvenient truths risk destroying their &apos;'Besserwisser'&apos; illusions. An example of this is a letter from Germany&apos;s federal environment minister Barbara Hendricks to her French counterpart Segolene Royal. The subject of the letter was the closure of France&apos;s Fessenheim nuclear power plant. The content of the letter appears to show that, not content with stamping out the use of nuclear energy in Germany and all the knowledge and industrial expertise that goes with it, Germany seems intent on imposing its point of view onto its neighbour. Hendricks acknowledges that any decisions relating to Fessenheim are for France alone as a sovereign nation. But, if that is the case, why bother to write the letter in the first place? In reply Royal, a prominent French Socialist, stresses French president Francois Hollande&apos;s desire to close Fessenheim before his term of office draws to a close. Royal also noted that it is up to France&apos;s nuclear operator, EDF, to &apos;&apos;define which reactors are removed from the grid&apos;&apos;. It is also amusing to read Royal&apos;s comment that the fact Fessenheim can be closed at all is largely due to the construction of replacement nuclear capacity at Flamanville, in northern France. Surely that irony could not have been lost on Germany&apos;s environment ministry.

The project, whose goal was to demonstrate the potential of tandem cells consisting of a combination of micro-crystalline and amorphous solar cells, has spawned world-wide interest and also initiated much research into the use of VHF-GD (Very High Frequency Glow-discharge) techniques to deposit thin films. Individual results achieved at IMT including those from investigations into micro-crystalline structures and textures and their absorption enhancement effects, electronic transport, improvement of open-circuit voltage, deposition rates, patterning techniques and increasing stabilised efficiencies are listed. A first Micromorph 23.6 cm{sup 2} mini-module using an integrated electric series connection concept is mentioned and advances in the IMT&apos;s infrastructure and facilities are described.

    Recently Yampol&apos;skii et al.[Phys. Rev. A 82, 032511 (2010)] advocated that Lifshitz theory is not applicable when the characteristic wavelength of the fluctuating electromagnetic field, responsible for the thermal correction to the Casimir force, is larger than the size of the metal test bodies. It was claimed that this is the case in experiments which exclude Lifshitz theory combined with the Drude model. We calculate the wavelengths of the evanescent waves making the dominant contribution to the thermal correction and we find that they are much smaller than the sizes of the test bodies. The opposite conclusion obtained by the authors arose from confusion between propagating and evanescent waves.

  7. A revised picture of the structure of the &apos;'monsoon'&apos; and land ITCZ over West Africa

    This article presents an overview of the land ITCZ (Intertropical Convergence Zone) over West Africa, based on analysis of NCAR-NCEP Reanalysis data. The picture that emerges is much different than the classic one. The most important feature is that the ITCZ is effectively independent of the system that produces most of the rainfall. Rainfall linked directly to this zone of surface convergence generally affects only the southern Sahara and the northern-most Sahel, and only in abnormally wet years in the region. A second feature is that the rainbelt normally assumed to represent the ITCZ is instead produced by a large core of ascent lying between the African Easterly Jet and the Tropical Easterly Jet. This region corresponds to the southern track of African Easterly Waves, which distribute the rainfall. This finding underscores the need to distinguish between the ITCZ and the feature better termed the &apos;&apos;tropical rainbelt&apos;&apos;. The latter is conventionally but improperly used in remote sensing studies to denote the surface ITCZ over West Africa. The new picture also suggests that the moisture available for convection is strongly coupled to the strength of the uplift, which in turn is controlled by the characteristics of the African Easterly Jet and Tropical Easterly Jet, rather than by moisture convergence. This new picture also includes a circulation feature not generally considered in most analyses of the region. This feature, a low-level westerly jet termed the African Westerly Jet, plays a significant role in interannual and multidecadal variability in the Sahel region of West Africa. Included are discussions of the how this new view relates to other aspects of West Africa meteorology, such as moisture sources, rainfall production and forecasting, desertification, climate monitoring, hurricanes and interannual variability. The West African monsoon is also related to a new paradigm for examining the interannual variability of rainfall over West

    In the late autumn of 2009, the Life and Style hotel &apos;Kameha Grand Bonn&apos; (Bonn, Federal Republic of Germany) was opened. It lies regionally beautiful at the &apos;Bonn Bogen&apos; on the right side of the River Rhine. Owner and investor of the 100 million Euro expensive project is the private inventory owner BonnVisio Real Estate GmbH and Co. KG (Bonn, Federal Republic of Germany). The extravagant and unmistakable hotel architecture with a building silhouette dropping to the River Rhine was developed by the architect Karl-Heinz Schommer (Bonn, Federal Republic of Germany). By means of a symbiosis from passive solar power, cooling system and resources conservating climate concept based on geothermal energy, the hotel fulfils the requirements of a Green Building.

    This report represents the final phase of Swiss Federal Office of Energy project &apos;Strategy for long-term management of city-owned real estate - the case of the City Council of Chiasso&apos;. It contains a comparative analysis of two tools for the evaluation of the potential for retrofitting and refurbishment of buildings (Retrofit Advisor and Epiqr+). By applying the two tools in parallel, it was possible to compare information and data obtained, and also to obtain indications for the evaluation of the usability of the tools. To achieve this, five buildings in the territory of the city of Chiasso were submitted to the tools for analysis. The applications have highlighted the usability of each case study. The ease of use of Retrofit Advisor has allowed the evaluation of each proposed scenario; by using the same reference system, comparable data are obtained (at indication level) to support the choice of the intervention strategy on existing buildings. In addition to the analysis of the current status, the tool Retrofit Advisor supports a structure analysis over three intervention scenarios, namely reparation, renovation, rebuild. Data entry does not require advanced knowledge of construction work, and is limited to basic characteristics. The analysis performed through Epiqr+ is more rigorous, providing a specific and detailed diagnosis on the state of deterioration of each construction element, supported by a series of intervention suggestions. The Epiqr+ tool has furthermore allowed the evaluation (within a precision range of {+-}15%) the cost of reparation/renovation works, and also the thermal energy balance of each building, based on the characteristics of their envelops. On the basis of contents criteria and cost analysis, the approach has allowed the evaluation of different options for the improvement of the buildings, from simple reparation to total rebuild. Estimates are evaluated in terms of cost, of environmental impact, and, in the case of Retrofit

    Introduction Depression is considered an independent risk factor for hypertension, particularly for people with recurrent episodes or a long history of depression. Another risk factor for cardiovascular disease is the Apolipoprotein E e4 allele (ApoE e4). The aim of this study was to examine how ApoE e4 was related to blood pressure (BP) in patients with depression and a control group. Methods A total of 78 patients, 49 with depression and 29 without, all recruited from the same hospital, underwent ApoE e genotyping (24 had at least one ApoE e4 allele) and examination of BP. Results In the depression group, but not in the control group, both systolic and diastolic BP were significantly higher in patients with ApoE e4 than in those without. The effect of ApoE e4 on BP differed significantly between the two groups. Conclusion Our findings showed that the effect of ApoE e4 on BP differed between the patients with depression and the control group. In patients with depression, ApoE e4 was associated with an increase in BP. We suggest that patients with depression and ApoE e4-positive status are particularly prone to develop BP elevation.

    The analytical sensitivity of radionuclide &apos;'milk'&apos; scans for detecting gastro-oesophageal reflux (GOR) has been assessed using an in vitro simulation test. Five factors were found to affect the ability to detect simulated reflux: isotope concentration, absolute gamma camera sensitivity, absorber thickness overlying the &apos;'oesophagus'&apos; and volume and duration of reflux. We found that a critical volume-duration product must be exceeded for reflux to be detected. Radionuclide milk scanning appears to be much less sensitive in detecting transient events like GOR than might be expected from previously reported static simulation studies.

    We hypothesized that the magnitude of the association between plasma homocysteine concentration and cognitive performance is larger for ApoE-epsilon4 carriers than for non-carriers. Nine hundred eleven dementia-free and stroke-free subjects (59% women) from the Maine-Syracuse study (26-98 years old) were stratified into no-ApoE-epsilon4 (n=667) and ApoE-epsilon4 carrier (n=244) cohorts. Employing a cross-sectional design and multiple regression analyses, plasma homocysteine was related to multiple domains of cognitive performance within these cohorts. When unadjusted, and with adjustment for age, education, gender, ethnicity, and previous cognitive examinations, homocysteine concentrations were inversely related to cognitive performance within both ApoE cohorts, with higher magnitude of associations within the ApoE-epsilon4 cohort. With adjustment for cardiovascular disease risk factors, cardiovascular disease, and B-vitamin concentrations, the higher magnitude of associations between plasma homocysteine and cognitive performance within the ApoE-epsilon4 cohort relative to the no-ApoE-epsilon4 cohort persisted; but associations of plasma homocysteine and cognitive performance were attenuated and no longer significant within the no-ApoE-epsilon4 cohort. Presence of the ApoE-epsilon4 allele modifies the relation between plasma homocysteine and cognitive performance. PMID:18023533

    The purpose of this study is to clarify the prevalence, spectrum of associated tumors and the diagnostic value of the linear meningeal thickening and enhancement adjacent to a peripherally located cranial mass &apos;dural tail sign&apos; (DTS) in contrast enhanced magnetic resonance imaging (MRI). In this prospective descriptive cross-sectional study conducted from 2002 to 2005, 110 patients with imaging-proven intracranial lesions and no history of previous intracranial surgery were referred to the neurosurgery clinic of our hospital for surgical resection. All underwent imaging with a 1.5 T MR system with and without contrast injection. Twelve patients were excluded from our study and finally 98 patients were evaluated for the presence of &apos;dural tail sign&apos;. Twenty-two of 98 patients (22.44%) with intracranial masses exhibited the &apos;dural tail sign&apos; (18 meningiomas, 2 pituitary adenomas, 1 primary cerebral lymphoma and 1 fungal brain abscess). Fifty-eight percent of the patients with biopsy-proven meningioma were observed to show &apos;dural tail sign&apos;. In conclusion, we found the &apos;dural tail sign&apos; to have a sensitivity of 58.6% and specificity of 94.02% in diagnosis of meningioma.

  14. &apos;ORIENT-Cycle&apos; - Evolutional Recycle Concept with Fast Reactor for Minimising High Level Waste

    International Nuclear Information System (INIS)

    JNC has proposed an evolutional concept of fast reactor recycle system for minimizing high-level waste (HLW) by adopting an unconventional recycling scheme based on the idea of &apos;rough removal of unnecessary elements&apos; instead of a conventional one as &apos;pure recovery of necessary elements&apos;. The concept was named &apos;ORIENT-cycle&apos; (Optimization by Removing Impedimental Elements). &apos;Unnecessary elements&apos; to be removed were listed up from various aspects such as core design, front end and back end of the fuel cycle. Stable fission products that amount to about 60 wt% of all FPs were identified as one category of key &apos;unnecessary elements&apos; from a neutronic aspect and also final disposal aspect because they were major parasitic neutron absorbers if recycled and were not required to be disposed in deep geological media. Adaptable separation schemes and the neutronic feasibility of the multi-recycling were discussed. The production rate of HLW was reduced by a factor of around 10 compared with a conventional cycle.

    Here we present high cadence photometry taken by the Acquisition Camera on Gemini South, of a close passage by the {approx}540 km radius Kuiper belt object, (50000) Quaoar, of a r&apos; = 20.2 background star. Observations before and after the event show that the apparent impact parameter of the event was 0.&apos;&apos;019 {+-} 0.&apos;&apos;004, corresponding to a close approach of 580 {+-} 120 km to the center of Quaoar. No signatures of occultation by either Quaoar&apos;s limb or its potential atmosphere are detectable in the relative photometry of Quaoar and the target star, which were unresolved during closest approach. From this photometry we are able to put constraints on any potential atmosphere Quaoar might have. Using a Markov chain Monte Carlo and likelihood approach, we place pressure upper limits on sublimation supported, isothermal atmospheres of pure N{sub 2}, CO, and CH{sub 4}. For N{sub 2} and CO, the upper limit surface pressures are 1 and 0.7 {mu}bar, respectively. The surface temperature required for such low sublimation pressures is {approx}33 K, much lower than Quaoar&apos;s mean temperature of {approx}44 K measured by others. We conclude that Quaoar cannot have an isothermal N{sub 2} or CO atmosphere. We cannot eliminate the possibility of a CH{sub 4} atmosphere, but place upper surface pressure and mean temperature limits of {approx}138 nbar and {approx}44 K, respectively.

    The strategy obviously adopted by the well-established manufacturers is to offer &apos;easy-to-handle&apos; equipment to gain new customers, and there is a variety of new compact systems or personal computers being put on the market. The changes and improvements within the processing sector proceed more or less in silence; high-capacity storage devices and multiprocessor configurations are obtainable at a moderate price, offering a greater variety of basic functions and enhanced control possibilities. Redundancy problems are handled with greater flexibility, and batch programs are advancing. Data communication has become a common feature, transmission speed and bus length have been improved. Important improvements have been made with regard to data display; even medium-sized equipment now offer the possibility of making dynamic flow-sheets and reserving space for process history display, and the hierarchy of displays has been considerably simplified. The user software also has been made more easy, &apos;fill-in-the-blancs&apos; is the prevailing motto for dialog configurations, and such big terms as process computer&apos; or &apos;programming skill&apos; are passing into oblivion.

    The German market for technically matured solar-thermal systems for generating hot water is growing by 20 per cent per year, with some deviations due to incentive policies. This growth can be and is planned to be increased systematically, with following goals: A practical contribution to the Federal Government&apos;s efforts to achieve the goals regarding the protection of climate; creating future-oriented jobs; supporting ecologically sustainable ways of life and models of consumption by convincing the consumers and other target groups of the fact that it makes sense already today to start utilizing solar energy and to invest also on private basis. These targets are expected to be set up with the help of a three-year mass campaign (1999 until 2001), i.e. the campaign called &apos;&apos;Solar - na klar.&apos;&apos; (solar - of course). [German] Der deutsche Markt fuer die technisch ausgereiften solarthermischen Anlagen zur Warmwassererzeugung waechst mit ca. 20% p.a., mit foerderpolitisch bedingten Schwankungen.

    This report deals with the works undertaken by working committee 10 during the 1997 - 2000 Triennium. The objective set by the IGU consisted in studying the generic thema in gas markets development for the less developed countries, in the developing countries with intermediate revenue as well as in the transitional economy countries. The first study group devoted his works to the problematic analysis of natural gas in the less developed countries, those where the GNP per capita is very low and the internal markets of which are little or non dynamic. This analysis has been developed in a certain number of countries rather representative of their respective region: Angola, Cameroon and Cote d&apos;Ivoire for sub-Saharian Africa, Bangladesh and Vietnam for Asia. The second study group analysed the changes in transitional economy countries (Baltic, countries in Central Europe and Ukraine) and their different consequences on gas industry. These countries apply gas industry reforms which are not implemented at the same rate more especially as they belong to a huge and very contrasted geographic region. The third study group devoted his works to the analysis of intensified conditions in the use of natural gas in the developing countries with intermediate revenue. He also examined the feasibility of an economic development in gas distribution networks in large cities. Two important issues focused his attention: financing and technology transfer. (author)

    Service pipes are constitute an important link in the gas distribution chain. By their numbers, their relative weakness against third party aggressions and due to the fact that they constitute in most cases the limit of responsibility between the gas company network and customers&apos; installations, service pipes have been identified as a technical and economical key issue for the gas industry development. This document analyses technical and economical data dealing with domestic service pipes having a maximum flow rate of 10 m3/h collected from 42 gas companies spread over 22 countries. All service pipes elements, from the connection with the distribution network up to the delivery point, are analysed emphasizing their layouts and design, the materials used, the construction techniques, the operating and maintenance policies and a few rehabilitation techniques. The main different technical solutions given by the gas companies have been compared in order for the study group to draw up some recommendations regarding the best practices in terms of safety, ease of maintenance and economical savings.

    Full Text Available Abstract Background The physiological regulation of hepatic apoE gene has not been clarified, although the expression of apoE in adipocytes and macrophages has been known to be regulated by LXR. Methods and Results We investigated the effect of TO901317, a LXR agonist, on hepatic apoE production utilizing HepG2 cells cultured in spheroid form, known to be more differentiated than HepG2 cells in monolayer culture. Spheroid HepG2 cells were prepared in alginate-beads. The secretions of albumin, apoE and apoA-I from spheroid HepG2 cells were significantly increased compared to those from monolayer HepG2 cells, and these increases were accompanied by increased mRNA levels of apoE and apoA-I. Several nuclear receptors including LXRα also became abundant in nuclear fractions in spheroid HepG2 cells. Treatment with TO901317 significantly increased apoE protein secretion from spheroid HepG2 cells, which was also associated with the increased expression of apoE mRNA. Separation of the media with FPLC revealed that the production of apoE-rich large HDL particles were enhanced even at low concentration of TO901317, and at higher concentration of TO901317, production of VLDL particles increased as well. Conclusions LXR activation enhanced the expression of hepatic apoE, together with the alteration of lipoprotein particles produced from the differentiated hepatocyte-derived cells. HepG2 spheroids might serve as a good model of well-differentiated human hepatocytes for future investigations of hepatic lipid metabolism.

    On 8 and 9 November 2007, the low-pressure system &apos;'Tilo'&apos;, with maximum wind speeds of 120 km/h (12 Bft), crossed the German Bight. In the afternoon of 9 November, the low caused waves with significant wave heights in excess of 10 m, corresponding to a maximum wave height of 17 - 18 m, wave periods of about 15 s and wave lengths of more than 220 m, which constitute extreme values in this sea area. On the FINO 1 research platform, the working platform was damaged at a height of 15 m above chart datum, repeating the occurrence of 1 November 2006 when the low-pressure system &apos;'Britta'&apos; had caused damage. Also this time, the highest wave crests reached nearly 45 m above ground, which is about 1.5 m above the level of the working platform. A storm and wave event of this magnitude in two consecutive years is an exceptional occurrence. The research platform FINO 1 is located at position N 54 0.86&apos;E 6 35.26&apos;, about 45 km north of Borkum. FINO 1 is used to make comprehensive physical, hydrological, chemical and biological measurements in preparation for the erection of offshore wind farms. Storm &apos;'Tilo'&apos; of 9 November 2007 again caused damage to the working platform of FINO 1, only a short time after the damage caused by storm &apos;'Britta'&apos; on 1 November 2006 had been repaired. Among other damage, solid wooden planks several centimetres thick were broken loose from their mountings 15 m above chart datum and destroyed by wash of the sea (Fig. 1). Exactly one year earlier the tempest &apos;'Britta'&apos; had caused severe damage, e.g. metal railings were bent and broken, and screw-fastened floor gratings were torn from their mountings.

    Purpose: Intensity modulated radiation therapy (IMRT) utilizes the technology of multileaf collimators to deliver highly modulated and complex radiation treatment. Dosimetric verification of the IMRT treatment requires the verification of the delivered dose distribution. Two dimensional ion chamber or diode arrays are gaining popularity as a dosimeter of choice due to their real time feedback compared to film dosimetry. This paper describes the characterization of a novel 2D diode array, which has been named the &apos;&apos;magic plate&apos;&apos; (MP). It was designed to function as a 2D transmission detector as well as a planar detector for dose distribution measurements in a solid water phantom for the dosimetric verification of IMRT treatment delivery. Methods: The prototype MP is an 11 x 11 detector array based on thin (50 {mu}m) epitaxial diode technology mounted on a 0.6 mm thick Kapton substrate using a proprietary &apos;'drop-in'&apos; technology developed by the Centre for Medical Radiation Physics, University of Wollongong. A full characterization of the detector was performed, including radiation damage study, dose per pulse effect, percent depth dose comparison with CC13 ion chamber and build up characteristics with a parallel plane ion chamber measurements, dose linearity, energy response and angular response. Results: Postirradiated magic plate diodes showed a reproducibility of 2.1%. The MP dose per pulse response decreased at higher dose rates while at lower dose rates the MP appears to be dose rate independent. The depth dose measurement of the MP agrees with ion chamber depth dose measurements to within 0.7% while dose linearity was excellent. MP showed angular response dependency due to the anisotropy of the silicon diode with the maximum variation in angular response of 10.8% at gantry angle 180 deg. Angular dependence was within 3.5% for the gantry angles {+-} 75 deg. The field size dependence of the MP at isocenter agrees with ion

    Low-friction tyres and oils as well as ecological driver training have proven to hold a considerable short-term CO{sub 2} reduction potential. By starting an initiative for the &apos;&apos;reduction of CO{sub 2} emissions from road traffic&apos;&apos; DUH has made a substantial contribution to implementing short-term measures in road traffic. Especially the workshop for fleet managers has provided important insights for the implementation of short-term measures. DUH has succeeded in presenting itself as professional partner of the Federal Environmental Office as well as a representative of the automobile, crude oil and tyre industry. This cooperation will facilitate the future implementation of climate protection measures in the area of road traffic. The intensive exchange of experience and the information collected in the course of the project have prepared the ground for further activities by other organisations. The German-American cooperation with environmental associations and environmental authorities has demonstrated the expedience of the &apos;&apos;Cars and Climate&apos;&apos; network. All parties involved have indicated their interest in continuing the project if there is a sufficient financial and organisational basis. Furthermore, all partners would greatly welcome an expansion of the existing network to the European level.

    OAK B139 The postgenomic era is arriving faster than anyone had imagined--sometime during 2000 we&apos;ll have a large fraction of the human genome sequence. Heretofore, our understanding of function has come from non-industrial experiments whose conclusions were largely framed in human language. The advent of large amounts of sequence data, and of &apos;&apos;functional genomic&apos;&apos; data types such as mRNA expression data, have changed this picture. These data share the feature that individual observations and measurements are typically relatively low value adding. Such data is now being generated so rapidly that the amount of information contained in it will surpass the amount of biological information collected by traditional means. It is tantalizing to envision using genomic information to create a quantitative biology with a very strong data component. Unfortunately, we are very early in our understanding of how to &apos;&apos;compute on&apos;&apos; genomic information so as to extract biological knowledge from i t. In fact, some current efforts to come to grips with genomic information often resemble a computer savvy library science, where the most important issues concern categories, classification schemes, and information retrieval. When exploring new libraries, a measure of cataloging and inventory is surely inevitable. However, at some point we will need to move from library science to scholarship.We would like to achieve a quantitative and predictive understanding of biological function. We realize that making the bridge from knowledge of systems to the sets of abstractions that constitute computable entities is not easy. The After the Genome meetings were started in 1995 to help the biological community think about and prepare for the changes in biological research in the face of the oncoming flow of genomic information. The term &apos;&apos;After the Genome&apos;&apos; refers to a future in which complete inventories of the gene products of

If larger planetesimals were present, then they would stir the disk, triggering a collisional cascade and thus causing production of small debris, which is not seen. Thus, planetesimal formation, at least in the outer regions of the systems, has stopped before &apos;cometary&apos; or &apos;asteroidal&apos; sizes were reached.

    This review describes the projects active during the years 2000-2003. Types and volumes of waste in Sweden: Consumption waste is waste from use of goods and services. Examples of consumption waste are household waste, non-branch specific industrial waste, building and demolition waste, park and garden waste, sludges from purification plants and private sewage. Production waste is generated in industry and agriculture. In 1998 Statistics Sweden performed a mapping of waste volumes and management in Sweden. This year 9.805 M tons consumption waste and 19.680 Mton production waste (excluding mine wastes) were generated. Since then, waste volumes have increased with 2-3%/year. Local communities, public sector and private waste management companies handled 7.7 M tons of waste for biologic processing, incineration with heat recovery or disposal, of these, 5.7 M tons are appreciated to have been combustible and other organic waste. In the programme, the subject &apos;System studies&apos; comprised three projects: &apos;Systems analysis of energy recovery from waste&apos;, &apos;Robust strategies for recovery of energy from waste&apos;, and &apos;Waste as fuel - An integrated study of the energy- and waste management system&apos;. The subject area &apos;Incineration and gasification&apos; included the following projects: &apos;Catalytic combustion of gasified waste&apos;, &apos;Gas cleaning in energy recovery from waste using new technology&apos;, &apos;Catalytic decomposition of chars in gasified waste&apos;, &apos;Cocombustion of biofuel and sorted household waste - Full scale trials Bjurholm&apos;, &apos;Incineration of waste - a review of research and development work&apos;, &apos;Energy from waste through gasification and direct combustion of the gas&apos;, &apos;Carbonate stabilization of RDF-ashes&apos;, &apos;Stabilization of ashes from incineration of waste in fluidized bed boilers&apos;, &apos;Dioxins and other environmental toxins i fly ashes and slags from

    Full Text Available ABSTRACT OBJECTIVE: Although self-etching bonding systems (SES are indicated to prepare dental enamel for bonding, concerns have been expressed regarding their effectiveness. The aim of this study was to analyze the etching pattern (EP of nine SES in comparison with 35% and 34% phosphoric acid etchants (FA on intact (IN and ground (GR enamel surface. MATERIALS AND METHODS: Twenty-two human third molars were sectioned in mesial-distal and buccal-lingual directions, and four dental fragments were obtained from each tooth. Half of the fragments were ground using 600-grit SiC paper and the other half remained intact. The fragments were randomly assigned into 22 groups, according to the texture of enamel surface (IN and GR and the technique to etch the enamel (34% FA, 35% FA, AdheSE primer; Brush & Bond; Clearfil Protect Bond primer; iBond; One-up Bond F; OptiBond Solo Plus primer; Tyrian SPE primer; Unifil Bond primer and Xeno III. Conditioners were applied to IN and GR enamel surfaces, according to the manufacturer's instructions. Specimens etched with phosphoric acids were washed with water, while the surfaces treated with SES were submitted to alternate rinsing with alcohol and acetone. The specimens were dried, sputter-coated and examined under a scanning electron microscope. RESULTS: For both IN and GR enamel surfaces, the EP of 34 and 35% FA was deeper and more homogeneous in comparison to EP of SES, except for Tyrian SPE. The acidic monomer action of self-etching systems was more effective on GR enamel. CONCLUSION: Most of the SES are less aggressive than phosphoric acid etchants and their etching effects were reduced on intact enamel surfaces.OBJETIVO: Apesar dos sistemas adesivos autocondicionantes (SAA serem indicados para aplicação no esmalte dental, preocupação tem sido relatada com relação a sua efetividade. O objetivo deste estudo foi avaliar o padrão de condicionamento ácido (PCA promovido por nove SAA e comparar ao PCA

    The expressions &apos;calibration&apos; and &apos;external calibration&apos; appear together in the present literature of atomic spectrometry resulting in a dilemma of understanding and correct use. It is examined how the IUPAC can provide a guidance to the solution of this problem by recalling the definitions of related terms of optical, mass and X-ray atomic spectrometry techniques. The introduction and definition of these expressions in widely used text books are investigated and statistically evaluated for the articles published during the last 30 years in the periodical Spectrochimica Acta Part B. For the elimination of the literary difficulties with the use of the term &apos;calibration&apos;, attributes are proposed to express the degree of matrix matching of standards and samples.

    2002-08-01

    This report provides a comparison of the features, events and processes (FEPs) identified by the Swedish Nuclear Fuel and Waste Management Company, SKB, with those of the Swedish Nuclear Power Inspectorate (SKI) and the Swedish Radiation Protection Authority (SSI), the latter identified as the basis for SKI/SSI&apos;s independent assessment calculations relating to the SFR 1 repository. Both SKB and SKI use the systems analysis approach as the framework for carrying out performance assessment (PA) calculations, although the specific details of their assessment methodologies vary. The review was conducted on two levels of detail: Top-level review, where FEP titles and Influences were compared between SKB and SKI/SSI documents, and A more in-depth review, where attention was paid to how a particular FEP was treated within the SKB assessment, by reference to SKB&apos;s Information Flow Network diagrams. With regard to findings of the review, in the near-field, a few SKB FEPs were not included in SKI&apos;s assessment: &apos;Osmosis&apos;, &apos;Heat-generating reactions&apos;, &apos;Heat conduction&apos;, &apos;Water pressure (influence on stress conditions)&apos;, &apos;Advection (advective transport of microbes)&apos; and &apos;Capillary suction&apos;. Of these, &apos;Heat-generating reactions&apos;, &apos;Heat conduction&apos; and &apos;Water pressure&apos; were not considered further in the SKB assessment. Similarly, the two-phase flow aspects of saturation were ignored. Of the remaining FEPs, it is not clear to what extent osmosis and the advective transport of microbes were taken into account in SKB&apos;s assessment. A few SKB FEP titles were not identified explicitly in SKI&apos;s FEP titles, although these may be considered as part of the description under existing SKI FEPs, i.e. at a different level of detail (e.g. &apos;Ion exchange&apos;, considered under SKI&apos;s &apos;Degradation and alteration of bentonite backfill&apos;). Finally, the SKB FEP &apos;Methylation/transformation&apos

    Environmentalist Bruno Comby, founder of the lobby group Environmentalists For Nuclear, says the anti-nuclear lobby has transformed a very safe energy source into a huge problem by distorting reality. He spoke to NucNet&apos;s Lubomir Mitev about risk, radiation and the &apos;problem&apos; of nuclear waste. Bruno Comby trained as a nuclear engineer at the Ecole Polytechnique and Ecole Nationale Superieure de Techniques Avancees de Paris. He established Environmentalists For Nuclear in 1996.

  17. Important points not mentioned in &apos;interim report&apos; of nuclear regulation authority

    International Nuclear Information System (INIS)

    The Nuclear Regulation Authority (NRA) published the investigation and examination report on the unexplained issues raised by the National Diet Investigation Commission; &apos;Analysis of the TEPCO Fukushima Daiichi NPS Accident-Interim Report&apos; in October 2014. The NRA had analyzed seven unexplained issues raised in the National Diet Investigation Commission report, and compiled the results. The author insisted the report should include related views and lessons learned and not just explain investigated and examined phenomena in order to contribute to ensuring nuclear safety in the world. As an example, the author selected the fifth of seven issues; &apos;operating status of the Isolation Condenser of Unit 1 (IC)&apos;. The report concluded &apos;the AC-driven valve was closed since the AC power supply kept working even after DC power supply for the IC rupture detection circuit was lost. The isolation valves (2A and 2B) outside the PCV were closed, but isolation valves (1B and 4B) of the IC (system &apos;B&apos;) in the PCV remained open. However, the operating status (open/close) of isolation valves (1A and 4A) of the IC (system &apos;A&apos;) in the PCV is not clear. It is therefore necessary to continue analyses of this issue.&apos; As related important points not mentioned in the report, the author described five points; (1) timing of functional losses of IC system, (2) obsolete aspect of equipment arrangement design (system separation), (3) single failure vulnerability, (4) rolling out issue of IC system to RCIC system (horizontal deployment) and (5) lessons learned from risk-informed &apos;black swan event&apos;.

    Prussian blue (PB) is an artists&apos; pigment that has been frequently used in many artworks but poses several problems of conservation because of its fading under light and anoxia treatment. PB fading is due to the reduction of iron(III) into iron(II) and depends a lot on the object investigated. Due to the complexity of the structure, the precise physico-chemical mechanisms behind the redox process remain obscure. In this paper, we present a procedure to investigate light- and anoxia-induced fading of PB-paper samples by means of time resolved X-ray absorption spectroscopy performed at the Fe K-edge. A system composed of a visible light source and a flux-controlled environmental cell allowed light, gas and humidity to be modified in situ. The synchrotron X-ray beam was evidenced to induce a reduction of PB and to play a major role in the kinetics. The analysis of the PB fading kinetics of a sample submitted to various gas and light environments showed that both synchrotron beam and anoxia were influencing PB reduction in a correlated way. In comparison, light was found to play a minor role. Finally, we have demonstrated that the type of paper substrate could influence significantly the kinetics of reduction. Several hypotheses to explain the correlation between PB reduction mechanism and substrate are presented. (orig.)

    In situ preserved latex (&apos;'Affenhaar'&apos;) has long been known from some of the Middle Eocene lignites of Central Germany. Now, for the first time, the occurrence of bark with latex canals still in situ has been studied in detail in the former mining area of the Geiseltal. Affenhaar is found in both massive matrix-dominated lignites and interbedded clastics, representing sub-autochthonous and reworked material, respectively. Palynological studies of Affenhaar-bearing sections reveal a highly diverse assemblage of spores and pollen, but none of the pollen taxa is obviously correlated to the occurrence of Affenhaar. A significant herbaceous component has been recognized in the pollen record in addition to those taxa mainly derived from trees. (author)

    This short article takes a look at the &apos;2000-Watt per person&apos; concept initially developed at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, in 1998. The author is of the opinion that the concept is not utopian but a vision that can be realised - providing it is accepted socially and that politics can implement it. Further work on the concept done at the ETH over the years is listed and commented on. A diagram provides an overview of energy resources, energy transformation and energy flows to final energy consumption. The question as to if the realisation of such a &apos;2000-Watt&apos;-society is actually necessary is posed.

    The cellulose industry generates huge amounts of solid waste residue called &apos;grits&apos;. These wastes have been willing over time in landfills near the mills. However, this type of disposal is not environmentally friendly and can cause degradation and environmental pollution. In addition, environmental legislation increasingly severe and the high costs of landfill have led the search for new alternatives for final disposition of this abundant waste. In this context, this study is to characterize waste grits, generated by the cellulose industry in the region of Aracruz-ES. The residue samples were characterized in terms of chemical composition, X-ray diffraction, particle size distribution and thermal analysis (DTA and TGA). The characterization of the residual &apos;grits&apos; demonstrated its potential as a feedstock for production of soil-cement bricks. (author)

    Since the end of the 70s international car manufacturers have adopted a new strategy with regard to the use of robots. Companies all over the world - headed by the Japanese car makers - decided not to &apos;dabble&apos; with industrial robots anymore but to &apos;blockbust&apos; with them. Complete production processes were literally turned inside out by the compact use of robots in waves, and adjusted to the requirements of flexible manufacturing technology. To deal with the characteristic conditions and features of the new strategy as well as its implications for labour policy, it is also necessary to examine the use of robots at the plant level. This study comes to the conclusion that the plant use of robots by no means follows a continuous curve, as would appear to be the case in industry and group statistics on the development of robot inventory.

  5. Bell&apos;s inequalities definitely proved

    International Nuclear Information System (INIS)

    According to quantum physics, two bonded particles instantly adopt the same behaviour when we measure them, whatever be the distance between them. For Einstein, this phenomenon could only be explained by the existence of hidden parameters which were not taken by quantum physics into account. Since the 1970&apos;s, experiments have been testing these ideas, based on the Bell&apos;s inequalities theorem which states that Einstein&apos;s assumptions are true within specific limits. The article more particularly presents and comments a recent experiment performed in Orsay which demonstrates that these hidden variables do not exist and prove the validity of Bell&apos;s inequalities. The researchers explain why previous experiments did not reach these results: they displayed detection and localisation defects

  6. Reconstruction of surface morphology from coherent scattering of &apos;'white'&apos; synchrotron radiation in hard X-ray regime

    Energy Dispersive Reflectometry (EDR) beamline at BESSY II provides &apos;'white'&apos; X-rays in the useful energy range of 5apos;'trivial'&apos; samples to determine the so called apparatus function. In addition I measured coherent reflectivity maps from thin film of highly scattering material of Pt with high atom number, Z=78 and patterned semiconducting surface like a GaAs surface grating which provides a certain periodicity in the measured scattering intensity. Finally I measured the surface speckles from a spatially confined Si wafer under the constraint that the size of the sample is smaller than the footprint of the incoming beam at the sample position. To reconstruct surface morphology from coherent reflectivity data is a typical inverse problem. Conventional phase retrieval algorithms like Gerchberg-Saxton (GS) algorithm, error reduction (ER) algorithm, hybrid input-output (HIO) algorithm are used in earlier work by other authors. I modified the conventional GS algorithm and ER algorithm which takes into account the additional Fresnel propagator term and also the illumination function at the sample position. I tested the modified algorithm successfully for a model surface in the form of a surface grating. I used the modified algorithm to reconstruct surface morphology from various static speckle measurements I performed at EDR beamline. The surface profiles reconstructed for different samples from the data at different energies (below the critical energy for the material at a particular incident angle) show almost the same roughness behavior for surface height with mean roughness of {proportional_to}1 nm. With the static speckle data I measured I could retrieve a one-dimensional picture of the sample surface with spatial

    The M51 system (NGC 5194/5195) provides an excellent problem both in spiral structure and in galaxy interactions. We present an analytic study of a computer experiment on the excitation mechanisms for M51&apos;s spiral arms and whether or not a halo is important for these mechanisms. This work extends previous numerical studies of the M51 system by including self-gravitation in a two component disk: gas&apos; and stars&apos;, and a dark halo. The analytic study provides two new observational constraints: the time ({approx}70-84 million years ago) and position angle of perigalacticon (300{degree}). By using these constraints and a simple conic approximation, the search for the companion&apos;s possible orbit is greatly simplified. This requires fewer N-body simulations than a fully self-gravitating orbit search. 8 refs., 4 figs.

    &apos;'Hair-on-end'&apos; skull changes are typically seen in individuals suffering from thalassaemia. They are induced by widening of the diploic space due to marrow expansion that is a consequence of ineffective and excessive erythropoiesis. We present a child with severe congenital neutropenia who exhibited the typical hair-on-end sign on plain skull radiographs and MRI. In this patient the skull changes were very likely induced by the expansion of white blood cell precursors induced by long-term daily injections of recombinant human granulocyte colony stimulating factor (G-CSF) to treat his confounding disease. This case report is the first description of hair-on-end changes associated with the use of G-CSF. (orig.)

    This work analyzes the progressive stiffening of the aorta due to atherosclerosis development of both ApoE(-/-) and C57BL/6J mice fed on a Western (n = 5) and a normal (n = 5) chow diet for the ApoE(-/-) group and on a normal chow diet (n = 5) for the C57BL/6J group. Sets of 5 animals from the three groups were killed after 10, 20, 30 and 40 weeks on their respective diets (corresponding to 17, 27, 37 and 47 weeks of age). Mechanical properties (inflation test and axial residual stress measurements) and histological properties were compared for both strains, ApoE(-/-) on the hyper-lipidic diet and both ApoE(-/-) and C57BL/6J on the normal diet, after the same period and after different periods of diet. The results indicated that the aorta stiffness in the ApoE(-/-) and C57BL/6J mice under normal diet remained approximately constant irrespective of their age. However, the arterial stiffness in the ApoE(-/-) on the hyper-lipidic diet increased over time. Statistical differences were found between the group after 10 weeks and the groups after 30 and 40 weeks of a hyper-lipidic diet. Comparing the hyper-lipidic and normal diet mice, statistical differences were also found between both diets in all cases after 40 weeks of diet, frequently after 30 weeks, and in some cases after 20 weeks. The early stages of lesion corresponded to the first 2 weeks of diet. Advanced lesions were found at 30 weeks and, finally, the aorta was completely damaged after 40 weeks of diet. In conclusion, we found substantial changes in the mechanical properties of the aorta walls of the ApoE(-/-) mice fed with the hyper-lipidic diet compared to the normal chow diet groups for both the ApoE(-/-) and C57BL/6J groups. These findings could serve as a reference for the study of changes in the arterial wall properties in cases of atherosclerosis. PMID:26502169

    The medial (M) an posteromedial cortical (C3) amygdaloid nuclei and the nucleus of the accessory olfactory tract (NAOT) are designated the &apos;&apos;vomeronasal amygdala&apos;&apos; because they are the only components of the amygdala to receive a direct projection from the accessory olfactory bulb (AOB). The efferents of M and C3 were traced after injections of /sup 3/H-proline into the amygdala in male golden hamsters. Frozen sections of the brains were processed for autoradiography. The efferents of the &apos;&apos;vomeronasal amygdala&apos;&apos; are largely to areas which are primary and secondary terminal areas along the vomeronasal pathway, although the efferents from C3 and M terminate in different layers in these areas than do the projections from the vomeronasal nerve or the AOB. Specifically, C3 projects ipsilaterally to the internal granule cell layer of the AOB, the cellular layer of NAOT, and layer Ib of M. Additional fibers from C3 terminate in a retrocommissural component of the bed nucleus of the strain terminalis (BNST) bilaterally, and in the cellular layers of the contralateral C3. The medial nucleus projects to the cellular layer of the ipsilateral NAOT, layer Ib of C3, and bilaterally to the medial component of BNST. Projections from M to non-vomeronasal areas terminate in the medial preoptic area-anterior hypothalamic junction, ventromedial nucleus of the hypothalamus, ventral premammillary nucleus and possibly in the ventral subiculum. These results demonstrate reciprocal connections between primary and secondary vomeronasal areas between the secondary areas themselves. They suggest that M, but not C3, projects to areas outside this vomeronasal network. The medial amygdaloid nucleus is therefore an important link between the vomeronasal organ and areas of the brain not receiving direct vomeronasal input.

    Schnitzler syndrome is characterized by chronic urticaria, monoclonal gammopathy, and a risk of developing lymphoproliferative disorders. Patients frequently present with bone pain, fever, arthralgia, and lymphadenopathy. The purpose of this study is to retrospectively review and evaluate potentially attributable imaging abnormalities in a series of patients with clinically diagnosed Schnitzler syndrome. Clinical and pathological chart review identified 22 patients meeting Strasbourg criteria for Schnitzler syndrome. Imaging of these patients was retrospectively reviewed by a musculoskeletal radiologist and a radiology fellow to determine and characterize significant &apos;'positive'&apos; findings that could potentially be attributed to their primary disease process. Evidence of abnormal bone remodeling was present in 64 % (14/22) of patients with 40 bone abnormalities. Lesions were predominantly or entirely sclerotic and most commonly involved the distal femora (n = 11), proximal tibiae (nine), and innominate bones (six). Patterns of involvement were variable, but typically eccentrically intramedullary, cortical, and juxta-articular. Skeletal surveys and targeted radiographs identified only 37 % (10/27) of abnormal bones subsequently &apos;'positive'&apos; by additional modalities. PET and bone scans were all positive in patients with bone sclerosis (13/13 and 17/17 bone sites, respectively). Schnitzler syndrome often presents with characteristic osteosclerosis, most commonly around the knees and in the pelvis. In patients with a suggestive clinical history, the radiologist could direct an appropriate imaging strategy or might to be the first to suggest the diagnosis. Bone scan may be the most appropriate initial screening tool in suspected cases. (orig.)

  4. A model-independent &apos;&apos;general search&apos;&apos; for new physics with the ATLAS detector at LHC

    International Nuclear Information System (INIS)

    The LHC particle collider accelerates bunches of protons at energies never reached before, thus opening a completely new landscape of new physics. In this scenario the number of possible physics processes and signatures becomes virtually infinite, making the setup of dedicated analyses impossible. Moreover there are regions of the phase-space where signals of new physics are not very likely to be found, or where suitable theoretical models are missing, and it is important to be able to reveal new processes from such regions as well. At the time this Thesis was started, no model-independent analysis had been set for the ATLAS experiment at LHC. The goal of this work was then to conceive and develop a new model-independent &apos;&apos;General Search&apos;&apos; for ATLAS, and to explore its possibilities. The new analysis has been then implemented and run over the first data which have been collected by the ATLAS experiment at a centre-of-mass energy of 7 TeV. This work presents the motivation of the data analysis, describes its implementation and shows the results. The data have shown a very good agreement with the Standard Model expectation and no evidence of new physics has been observed. Nevertheless, an efficient strategy and methodology for a new model-independent &apos;&apos;General Search&apos;&apos; have been defined and they are ready to be used in a next version of this analysis, over a larger set of experimental data. During this work, a new innovative software framework has been also conceived and developed to ease the implementation of physics analysis code using Computer-Aided- Software-Engineering (CASE) principles. The framework has been successfully used to analyze the very first LHC data, and then it has been transformed into an open-source modular framework for HEP data analysis, and presented at Physics and Computer Science international conferences.

    Persistent organochlorine pollutants (POP) have, in animal studies, impaired normal bone metabolism and resulted in increased bone fragility. Especially considering the dramatical increase in osteoporotic fractures in western societies during the last decades, it is a pertinent question whether a high dietary intake of POP might pose a risk for deteriorated bone quality in humans. This problem has been assessed as a part of the collaborative project &apos;'COMPARE'&apos;, funded by European Commission RD Life Science Program. As a study base we have used cohorts of Swedish fishermen&apos;s families. We have earlier shown that fishermen living at the east coast of Sweden, have a high consumption of contaminated fatty fish from the Baltic Sea and consequently relatively high exposure levels for various POPs, also compared with fishermen from the Swedish west coast. Such a discrepancy was also found for fishermen&apos;s wives. The aim of the project was to assess in epidemiological studies whether a high dietary intake of POP through fatty fish from the Baltic may result in an increased incidence of osteoporotic fractures or decreased bone mineral density (BMD). We give here an overview of the results.

    In this report a completely new approach to the distribution of District Heating Services is presented. The general idea of the solution, here presented under the name Comb Configurated Costumer close Network Installations with Underground Service Boxes (in the following referred to as Finnova AF), was given birth during a very early stage of the working process of the FDG. The goal for our &apos;Vaermegles&apos;- project (&apos;Vaermegles&apos; means for a residential area to have a low heat demand) is to present a technical solution that implies a substantial cost reduction for establishing DH in such low heat demand residential areas, when compared with what is recognized as to-day applied &apos;best technology&apos;. The aim point was, in the cost level of 2003/2004, VAT not included, a total investment sum of SEK 50,000 (about 7,000 USD). Using flexible piping, delivered to the site as coils of 100 m of pipes each, installed according to the Comb configuration principle, no joints installed directly in the ground are needed. The number of street crossings is strongly reduced, as compared with today&apos;s practice. The total of the joint assembly work takes place inside underground service boxes, situated at the building site boundaries. In this way the continuity of the building process is strongly improved. The stages of operation: digging, installing of pipes, backfilling and arranging of service boxes will take place in shortest possible time. As a prototype, the so called service box (e g a service and connection box, let us call it an &apos;S/C&apos; box) is square, made of concrete and will be installed with its roof 4-8 inches above ground. Inside the box, a fully equipped DH &apos;substation&apos;, designed as an easily replaceable cassette. In the prototype the closing cap is made from a galvanised steel sheet. The same box and cassette designs can be used for almost all single family houses with a heat demand not exceeding 10 kW. This gives a

    In the forty years since the war, things have been going gradually but progressively better for Bulgaria. An industry has been built up. As a tourist country, Bulgaria attracts millions of visitors from abroad every year. The Bulgarian agriculture has managed to overcome its hereditary malaise, the fragmentation of the arable land into small and tiny holdings. Environment burdens, soil erosion, air and water pollution are consequences of industrialization and socialistic agriculture. It is faire to speak of a conscious environmental policy in the case of Bulgaria only since the later half of the 60s. It was at that time that scientists first documented the deleterious side effects of industralization, and the State passed the first laws aimed at protecting the environment. In the 70s, environmental conservation in Bulgaria was institutionalized in bewildering multiplicity: the Legislative (National Assembly), the Executive (Government), the &apos;&apos;State Council&apos;&apos; (as a hybrid form of Legislative and Executive combined), and the umbrella organization &apos;&apos;Patriotic Front&apos;&apos; each set up their own bodies and institutions to be responsible for environmental conservation. Since 1977, the &apos;&apos;Environmental Protection Committee&apos;&apos; in the Council of Ministers has been acting as the supreme organ of control in this field. In the present-day ecology discussion there are a number of new and quite promising approaches - for example the &apos;&apos;agroecological brigades&apos;&apos; in the agriculture, a kind of ecological &apos;&apos;task force&apos;&apos;, by which the party leadership, in particular, places great hopes for the future.

    The apoE {epsilon}4 allele is associated with increased risk and decreased age of onset of AD. The {epsilon}4 allele may have opposing effects. We determined that family history of a parent or sib with memory problems (famhx+) modified the effect of apoE genotype in a population-based, case (n=165, 72 famhx+)-control (n=233, 73 famhx+) sample. Logistic regression analyses detected a significant apoE genotype (E) by family history (F) by age (A) interaction (ExFxA, p=0.003) and ExF interaction (p=0.0001) in the prediction of AD. ExFxA remained significant when only {epsilon}4+ genotypes were included (p<0.01). ExFxSex (p=0.04) and ExF (p<0.0001) were significant when only {epsilon}4- genotypes were included. Similary, multiple regression detected significant ExF interaction in the prediction of age of AD onset for {epsilon}4+ genotypes (p=0.04) or {epsilon}4- genotypes (p=0.04). Sex did not interact in the prediction of age of onset. Famhx+ increased risk of AD differentially and reduced age of onset except in {epsilon}2+ genotypes. Family history modifies the apoE genotype influence on risk and onset age of AD, suggesting that non-apoE genetic effects interact with apoE in AD. It is most predictive of risk in those with the {epsilon}2{epsilon}3 genotype. Variation in risk and onset among both {epsilon}4+ and {epsilon}4- genotypes demonstrate that {epsilon}2 and {epsilon}3 mediate {epsilon}4 allele effects in AD.

  16. Can Venezuela&apos;s oil sector endure Chavez&apos; ambitions any longer?; Kan Venezuela&apos;s oliesector Chavez&apos; ambities nog langer dragen?

    Honkoop, J.

    2009-07-15

    The author describes the decline of Venezuela&apos;s oil industry as well as President Chavez&apos; reaction to Venezuela&apos;s budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela&apos;s poor and he is searching desperately for ways to extract yet more from Venezuela&apos;s dysfunctional economy. As funds run out, Venezuela&apos;s expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela&apos;s impoverished masses, still supportive of Chavez during February&apos;s elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [Dutch] De auteur beschrijft de teruggang van de olie-industrie van Venezuela en de reacties van president Chavez op de budgettaire crisis in Venezuela. Politisering, dalende investeringen en de verplichtingen m.b.t. de overvloed aan sociale uitgaven zorgen er voor dat de nationale oliemaatschappij Petroleos de Venezuela niet in staat is om efficient te produceren en de productie op peil te houden. Dalende olie-productie en lagere olieprijzen zorgen er ook voor dat de president niet in staat is om de rijkdom te verdelen over de armen in Venezuela. Hij is op zoek naar manieren om meer te halen uit de slecht functionerende economie. Zijn dure buitenlandse Venezuela beleid, onder meer door ondersteuning van regionale bondgenoten, in het bijzonder Cuba, en het zoeken naar export mogelijkheden, behalve naar de USA, pakt fiancieel gezien slecht uit. De verarmde massa&apos;s van Venezuela steunden Chavez nog in de verkiezingen in

    This paper describes the program, the status, and the course of activities on rehabilitation of radioactively contaminated facilities and the territory of temporary radioactive waste (radwaste) disposal at the Russian Research Center &apos;&apos;Kurchatov Institute&apos;&apos; (RRC KI) in Moscow as performed in 2001-2002. The accumulation of significant amounts of radwaste at RRC KI territory is shown to be the inevitable result of Institute&apos;s activity performed in the days of former USSR nuclear weapons project and multiple initial nuclear power projects (performed from 1950&apos;s to early 1970&apos;s). A characterization of RRC KI temporary radwaste disposal site is given. Described is the system of radiation control and monitoring as implemented on this site. A potential hazard of adverse impacts on the environment and population of the nearby housing area is noted, which is due to possible spread of the radioactive plume by subsoil waters. A description of the concept and project of the RRC KI temporary radwaste disposal site is presented. Specific nature of the activities planned and performed stems from the nearness of housing area. This paper describes main stages of the planned activities for rehabilitation, their expected terms and sources of funding, as well as current status of the project advancement. Outlined are the problems faced in the performance and planning of works. The latter include: diagnostics of the concrete-grouted repositories, dust-suppression technologies, packaging of the fragmented ILW and HLW, soil clean-up, radioactive plume spread prevention, broad radiation monitoring of the work zone and environment in the performance of rehabilitation works. Noted is the intention of RRC KI to establish cooperation with foreign, first of all, the U.S. partners for the solution of problems mentioned above.

    Energy Technology Data Exchange (ETDEWEB)

    1991-10-01

    This report describes an energy-saving effect of the contra-rotating propeller-ship JUNO&apos;&apos; constructed by Ishikawajima-Harima Heavy Industries and a reliability of the contra-rotating shaft system after the ship was placed in service. On the basis of voyage reports of JUNO,&apos;&apos; a 37,000 DWT bulk carrier with 178.0m in length between perpendiculars, 28.4m in molded breadth, and 10.72m in molded depth, the operation characteristics of the contra-rotating propeller-ship and the durability of the shaft were evaluated. Consequently, the contra-rotating propeller system installed on JUNO&apos;&apos; was completely successful in practical use through the actual voyages over a period of more than two years and a half. In addition, it was found that the energy-saving effect of the contra-rotating propeller-ship JUNO&apos;&apos; is 15% higher than that of the conventional propeller ship. Furthermore, the contra-rotating shafting system demonstrated a high reliability even after the contra-rotating propeller was ice-damaged and bent. 7 refs., 15 figs., 1 tab.

    APOE ε4 (apoE4) polymorphism is the main genetic determinant of sporadic Alzheimer's disease (AD). A dietary approach (Fortasyn) including docosahexaenoic acid, eicosapentaenoic acid, uridine, choline, phospholipids, folic acid, vitamins B12, B6, C, and E, and selenium has been proposed for dietary management of AD. We hypothesize that the diet could inhibit AD-like pathologies in apoE4 mice, specifically cerebrovascular and connectivity impairment. Moreover, we evaluated the diet effect on cerebral blood flow (CBF), functional connectivity (FC), gray/white matter integrity, and postsynaptic density in aging apoE4 mice. At 10-12 months, apoE4 mice did not display prominent pathological differences compared to wild-type (WT) mice. However, 16-18-month-old apoE4 mice revealed reduced CBF and accelerated synaptic loss. The diet increased cortical CBF and amount of synapses and improved white matter integrity and FC in both aging apoE4 and WT mice. We demonstrated that protective mechanisms on vascular and synapse health are enhanced by Fortasyn, independent of apoE genotype. We further showed the efficacy of a multimodal translational approach, including advanced MR neuroimaging, to study dietary intervention on brain structure and function in aging. PMID:27034849

  7. First `Winged&apos; and `X&apos;-shaped Radio Source Candidates

    Energy Technology Data Exchange (ETDEWEB)

    Cheung, C.C.

    2007-01-22

    A small number of double-lobed radio galaxies (17 from our own census of the literature) show an additional pair of low surface brightness &apos;'wings'&apos;, thus forming an overall &apos;'X'&apos;-shaped appearance. The origin of the wings in these radio sources is unclear. They may be the result of back-flowing plasma from the currently active radio lobes into an asymmetric medium surrounding the active nucleus, which would make these ideal systems in which to study thermal/non-thermal plasma interactions in extragalactic radio sources. Another possibility is that the wings are the aging radio lobes left over after a (rapid) realignment of the central supermassive black-hole/accretion disk system due perhaps to a merger. Generally, these models are not well tested; with the small number of known examples, previous works focused on detailed case studies of selected sources with little attempt at a systematic study of a large sample. Using the VLA-FIRST survey database, we are compiling a large sample of winged and X-shaped radio sources for such studies. As a first step toward this goal, an initial sample of 100 new candidate objects of this type are presented in this paper. The search process is described, optical identifications from available literature data, and basic radio data are presented. From the limited resolution FIRST images ({approx} 5&apos;&apos;), we can already confidently classify a sufficient number of these objects as having the characteristic wing lengths >80% of the active lobes to more than double the number of known X-shaped radio sources. We have also included as candidates, radio sources with shorter wings (<80% wing to lobe length ratios), or simply &apos;'winged'&apos; sources, as it is probable that projection effects are important. Finally, among the candidates are four quasars (z=0.37 to 0.84), and several have morphologies suggestive of Fanaroff-Riley type-I (low-power) radio galaxies. While followup

  12. Accreting planets as dust dams in &apos;transition&apos; disks

    International Nuclear Information System (INIS)

    We investigate under what circumstances an embedded planet in a protoplanetary disk may sculpt the dust distribution such that it observationally presents as a &apos;transition&apos; disk. We concern ourselves with &apos;transition&apos; disks that have large holes (≳ 10 AU) and high accretion rates (∼10–9-10–8 M ☉ yr–1), particularly, those disks which photoevaporative models struggle to explain. Adopting the observed accretion rates in &apos;transition&apos; disks, we find that the accretion luminosity from the forming planet is significant, and can dominate over the stellar luminosity at the gap edge. This planetary accretion luminosity can apply a significant radiation pressure to small (s ≲ 1 μm) dust particles provided they are suitably decoupled from the gas. Secular evolution calculations that account for the evolution of the gas and dust components in a disk with an embedded, accreting planet, show that only with the addition of the radiation pressure can we explain the full observed characteristics of a &apos;transition&apos; disk (NIR dip in the spectral energy distribution (SED), millimeter cavity, and high accretion rate). At suitably high planet masses (≳ 3-4 MJ ), radiation pressure from the accreting planet is able to hold back the small dust particles, producing a heavily dust-depleted inner disk that is optically thin to infrared radiation. The planet-disk system will present as a &apos;transition&apos; disk with a dip in the SED only when the planet mass and planetary accretion rate are high enough. At other times, it will present as a disk with a primordial SED, but with a cavity in the millimeter, as observed in a handful of protoplanetary disks.

    To compare pre- and postnatal sonographic findings of ovarian cysts in neonates and to present a &apos;daughter cyst&apos; sign for uncomplicated ovarian cysts. The study group consisted of six cases of neonatal ovarian cysts which were evaluated by both prenata (mean, IUP 36 weeks+3 days) and postnatal(mean, 2 days after birth) ultrasound studies. Two ovarian cysts were confirmed by surgery and the remaining four were clinically diagnosed. Postnatal sonography was prospectively evaluated and prenatal ultrasound scans were retrospectively evaluated. The size, contents, and wall thickness of the cyst were evaluated. We also analyzed presence or absence of a &apos;daughter cyst&apos; , defined as a small cyst surrounded by a complete wall, protruding into the cyst lumen or along the cyst wall. Pathologic correlation of the daughter cyst was performed in two cases. The mean sizes of the ovarian cysts were 59.6 X 46.1 mm on prenatal and 73.0 X 49.2 mm on postnatal studies. Five were anechoic and thin walled cysts on both pre- and postnatal studies. One case revealed debris in the cyst lumen on prenatal study but was completely involuted on postnatal study. All six were unilocular in shape. The &apos;daughter cyst&apos; sign was seen in two on prenatal and in four (80%) on postnatal studies. The &apos;daughter cyst&apos; on sonography was corresponded to a follicle on pathology. The &apos;daughter cyst&apos; sign appeared to be helpful for the diagnosis of neonatal ovarian cyst on both pre- and postnatal ultrasound studies.

    Research highlights: The standard molar enthalpies of formation, in the condensed phase, of 3&apos;- and 4&apos;-nitroacetophenones have been determined by combustion calorimetry. The vapor pressures of the crystalline 3&apos;- and 4&apos;-nitroacetophenones were measured as function of temperature by the Knudsen effusion mass loss technique. The standard molar enthalpies, entropies and Gibbs functions of sublimation, at T = 298.15 K, were calculated for both compounds. - Abstract: The standard (p{sup o} = 0.1 MPa) molar enthalpies of formation, in the condensed phase, of 3&apos;- and 4&apos;-nitroacetophenones, presented in this work, were obtained from measurements of their combustion energies, at T = 298.15 K, using a static bomb calorimeter. The vapor pressures of the two crystalline 3&apos;- and 4&apos;-nitroacetophenones were measured as a function of temperature by the Knudsen effusion mass loss technique. The standard molar enthalpies of sublimation, at T = 298.15 K, were derived from the Clausius-Clapeyron equation. The standard molar enthalpies, entropies, and Gibbs functions of sublimation, at T = 298.15 K, were calculated for the two compounds. The experimental values obtained were used to calculate the standard molar enthalpies of formation of 3&apos;- and 4&apos;-nitroacetophenones, in the gaseous phase, as {Delta}{sub f}H{sub m}{sup 0}(g)=-(99.4{+-}1.6)kJ{center_dot}mol{sup -1} and {Delta}{sub f}H{sub m}{sup 0}(g)=-(99.1{+-}1.7)kJ{center_dot}mol{sup -1}, respectively, and these derived values are analyzed in terms of structural enthalpic increments.

    The article describes Ken Livingstone&apos;s plans for solving London&apos;s traffic problems: Derek Turner will be &apos;in charge of the capital&apos;s streets&apos; but Livingstone will chair the board meetings. The radical new scheme will apply to both the Greater London Authority, its transport branch Transport for London (TfL) and 33 London Boroughs. Within TfL there is a core division called &apos;street management services&apos; which has five area teams for day-to-day street management including road maintenance and street lighting. Other departments are communications, support services, traffic technology services, service development and performance, a London bus department and a department concentrating on congestion charging. There are plans to support pedestrians and cyclists but &apos;bus travel is really what it is all about&apos;.

    imaging techniques need to be validated in prospective clinical trials assessing the SMM to multiple myeloma transition, with the aim of enabling appropriate management decisions. Efforts are also needed to improve the costs and availability of whole-body MRI and/or FDG PET/CT, in order to facilitate their widespread adoption as first-line detection modalities. Future clinical trials of therapeutic agents using earlier detection strategies will have to be carefully designed and take into consideration the risk of lead-time and length-time biases, which might falsely demonstrate longer overall survival. The English full text version of this article is available at SpringerLink (under &apos;'Supplemental'&apos;). (orig.) [German] Aktuelle klinische Studien sprechen fuer eine Therapie des &apos;&apos;smoldering multiple myeloma&apos;&apos; (SMM) mit hohem Progressionsrisiko schon bei der Diagnosestellung und nicht erst zum Zeitpunkt der Progression in ein symptomatisches multiples Myelom (MM). Die Frueherkennung einer Knochen- und/oder Knochenmarkbeteiligung durch entsprechende sensitive Bildgebungsverfahren kann zur Ermittlung von SMM-Patienten mit hohem Risiko fuer eine Progression beitragen. Nach aktuellen Konsensusleitlinien (2011) ist die Roentgenuntersuchung des Skeletts ein Grundpfeiler der Beurteilung einer Knochenbeteiligung bei Diagnosestellung und in Verlaufskontrollen wegen eines SMM. Jedoch hat die Roentgenuntersuchung des Skeletts eine geringe Sensitivitaet fuer Knochenlaesionen und liefert keine Informationen zu Knochenmarkveraenderungen. Moderne bildgebende Verfahren wie die Fluordeoxyglukose-Positronenemissionstomographie-Computertomographie (FDG-PET-CT) und die Magnetresonanztomographie (MRT) liefern zusammen mit innovativen Funktionsuntersuchungen eine bessere Einschaetzung allgemeiner Veraenderungen im Knochenmark- und im Knochenkompartiment. Mit diesen Verfahren kann die beginnende Progression vom SMM zum MM quantitativ objektiviert werden

    The evaluation of the environmental quality objective &apos;A Safe Radiation Environment&apos; is a contribution to the Environmental Objective Council&apos;s assessment of progress towards the national environmental quality objectives. The report describes and evaluates the radiation environment in Sweden, the regulatory instruments, measures carried out and the monitoring programmes. Furthermore, the possibility of achieving the objective and its interim targets is evaluated. New measures and means of control are proposed. The proposals are directed to the government and Parliament, national authorities and other stakeholders in society. The Swedish Radiation Protection Authority (SSI) considers it possible to achieve the objective, but additional efforts are required to ensure success. Environmental monitoring, research on health effects of radiation and supervision are still important areas. Intensified efforts will be needed to change attitudes towards suntanning. Changes in the formulation of the objective and its interim targets are suggested. Today only protection against radiation in the external environment is covered by the objective. Radiation protection work has to consider all. SSI therefore suggests that the objective should extend to include workplaces and indoor environment. For the three interim targets included in &apos;A Safe Radiation Environment&apos;, changes are suggested for the interim targets for radioactive substances and electromagnetic fields. No change is suggested for the interim target for skin cancer

    An analysis of the Claude form of an idealized helium liquefier for the minimum input work reveals the &apos;&apos;Carnot Step&apos;&apos; for helium refrigerator cycles. As the &apos;&apos;Carnot Step&apos;&apos; for a multi-stage polytropic compression process consists of equal pressure ratio stages; similarly for an idealized helium liquefier the &apos;&apos;Carnot Step&apos;&apos; consists of equal temperature ratio stages for a given number of expansion stages. This paper presents the analytical basis and some useful equations for the preliminary examination of existing and new Claude helium refrigeration cycles.

    The kinetics of oxidation of uranium monocarbide either in dry or moist air or in oxygen-argon mixtures, has been studied thermogravimetrically, between 500 and 800 C in a circulating atmosphere. In all cases the oxidation leads to the formation of U{sub 3}O{sub 8}. Between 500 and 700 C, the activation energy is about 21 +3 kcal/mole. It seems to decrease between 700 and 800 C, but the reaction follows always a linear rate law. In moist air, the oxidation proceeds more swiftly, due to an increase in the reactional interface. An evaluation of the over-temperature has been made at 800 C.

L&apos;oxydation de UC par l&apos;air humide semble etre plus rapide surtout aux basses temperatures. Cette acceleration n&apos;est due, en fait, qu&apos;a une augmentation de la surface reactionnelle. Une estimation et une mesure de la surtemperature ont ete effectuees pour une temperature de 800 C.

    Full Text Available PURPOSE: This study aimed to assess the effects of preconditioning with mixtures of oils containing high/low ratio of ω-6/ω-3 and ω-9/ω-6, respectively, in an experimental model of cerebral ischemia-reperfusion (I/R. METHODS: Forty-two Wistar rats were randomly distributed into two groups: control (n=24 and test (n=18. Control group was subdivided in 4 subgroups (n=6: G1: Sham-Water; G2: I/R-Water; G3: Sham-Isolipidic and G4: I/R-Isolipid. The animals received water or a isolipid mixture containing ω-3 oils (8:1 ratio and ω-9/ω-6 (0.4:1 ratio by gavage for seven days. Test group included 3 subgroups (n=6 G5: I/R-Mix1, G: 6 I/R-Mix2 and G7: I/R-Mix3. Test group animals received oily mixtures of ω-3 (1.4:1 ratio and ω-6 (3.4:1 ratio, differing only in source of ω-3: G5 (alpha-linolenic acid; G6 (alpha-linolenic, docosahexaenoic and eicosapentaenoic acids, and G7 (alpha-linolenic and docosahexaenoic acids. On day 7 I/R rats underwent cerebral ischemia with bilateral occlusion of common carotid arteries for 1 hour followed by reperfusion for 3 hours. G1 and G3 animals underwent sham operation. Concluded the experiment, animals were decapitated and their brains sliced for red neurons (RN count in CA3 area of the hippocampus. Variables were compared using ANOVA-Tukey test. RESULTS: The use of different mix preparations promoted a decrease in red cell count in all three groups (G5/G6/G7, compared with G2/G4, confirming the protective effect of different oil blends, regardless of ω-3 source. CONCLUSION: Pre-conditioning with mixtures of oils containing high ratio ω-6/ω-3 and low ω-9/ω-6 relationship protects brain neurons against I/R injury in an experimental model.OBJETIVO: Avaliar os efeitos do pré-condicionamento com misturas de óleos contendo relação alta/baixa de ω-6/ω-3 e ω-9/ω-6, respectivamente, em um modelo experimental de isquemia/reperfusão (I/R cerebral.

    The synthesis of an Ru(II) complex derived from 4&apos;-(4-methacryloyloxymethylphenyl)- 2,2&apos;:6&apos;,2&apos;&apos; terpyridine ligand, together with its spectral and electrochemical properties, has been described. The application of this complex, which does not possess the usual anchoring groups like carboxylate or phosphate, in a dye sensitized nanocrystalline TiO{sub 2} solar cell has indicated a short circuit current of 0.252 mA, an open circuit potential of 377 mV with an overall efficiency of 3.63%. The overall conversion efficiency of the system remains stable for a long period due to the efficient electron injection into the conduction band during light absorption. The high resolution scanning electron microscopy picture reveals a three-dimensional network of interconnected nanoscale particles, while x-ray diffraction studies show that the particle size is 21 nm.

    Nowadays, percutaneous vertebroplasty, or its evolution kyphoplasty, is a valid therapeutic option for the management of severe back pain, caused by vertebral compression fractures (1). They are minimally invasive, radiologically guided interventional procedures, which involve the injection of polymethylmethacrylate (PMMA) into the fractured vertebral body. The injection process was monitored continuously, under a fluoroscopic control in the lateral plane (2). Ideally, the injection should be completed in 5 to 6 minutes and before the PMMA becomes too viscous to allow reinsertion of the stylus. This is not always possible, but is preferred to avoid the risk of leaving a &apos;needle castor a &apos;cement tail&apos;, within the soft tissues, as the needle is removed with the adherent cement (Fig. 1). In the event that the reinsertion cannot be achieved, great care should be taken to dislodge the adherent PMMA cement before extracting the needle from the vertebral body (3).

    The REIMEP-22 inter-laboratory comparison aimed at determining the production date of a uranium certified test sample (i.e. the last chemical separation date of the material). Participants in REIMEP-22 on &apos;&apos;U Age Dating - Determination of the production date of a uranium certified test sample&apos;&apos; received one low-enriched 20 mg uranium sample for mass spectrometry measurements and/or one 50 mg uranium sample for a-spectrometry measurements, with an undisclosed value for the production date. They were asked to report the isotope amount ratios n(230Th)/n(234U) for the 20 mg uranium sample and/or the activity ratios A(230Th)/A(234U) for the 50 mg uranium sample in addition to the calculated production date of the certified test samples with its uncertainty. Reporting of the 231Pa/235U ratio and the respective calculated production date was optional. Eleven laboratories reported results in REIMEP-22. Two of them reported results for both the 20 mg and 50 mg uranium certified test samples. The measurement capability of the participants was assessed against the independent REIMEP-22 reference value by means of z- and zeta-scores in compliance with ISO 13528:2005. Furthermore a performance assessment criterion for acceptable uncertainty was applied to evaluate the participants&apos; results. In general, the REIMEP-22 participants&apos; results were satisfactory. This confirms the analytical capabilities of laboratories to determine accurately the age of uranium materials with low amount of ingrown thorium (young certified test sample). The Joint Research Centre of the European Commission (EC-JRC) organised REIMEP-22 in parallel to the preparation and certification of a uranium reference material certified for the production date (IRMM-1000a and IRMM-1000b).

    Apolipoprotein E (APOE) is a multifunctional plasma protein mainly acting in lipid metabolism. Human APOE is polymorphic with three major isoforms (APOE2, APOE3 and APOE4). Up to 75% of the body's APOE is produced by the liver. There is increasing evidence from studies in brain-derived cells that APOE4 affects mitochondrial function and biogenesis as well as stress and inflammatory responses - processes, whose disturbances are considered hallmarks of the ageing process. However, although the liver is the main production site of APOE, knowledge about the impact of the APOE genotype on hepatic stress response-related processes is rather limited. Therefore, we studied biomarkers of oxidative status (glutathione levels, 3-nitrotyrosine adducts, protein carbonyl concentration), ER stress (XBP1(S), BiP, DDIT3), proteasome activity, mitochondrial function (respiratory complexes, ATP levels and mitochondrial membrane potential as well as biomarkers of mitochondrial biogenesis, fission and fusion), autophagy (LC3, LAMP2A), apoptosis (BCL2, BAX, CYCS) and DNA damage in the liver of APOE targeted replacement (TR) mice and in Huh7 hepatocytes overexpressing the APOE3 and the APOE4 isoform, respectively. APOE4 mice exhibited a lower chymotrypsin-like and a higher trypsin-like proteasome activity. Levels of protein carbonyls were moderately higher in liver tissue of APOE4 vs. APOE3 mice. Other biomarkers of oxidative stress were similar between the two genotypes. Under basal conditions, the stress-response pathways investigated appeared largely unaffected by the APOE genotype. However, upon stress induction, APOE4 expressing cells showed lower levels of adenosine triphosphate (ATP) and lower mRNA levels of the ATP-generating complex V of the mitochondrial respiratory chain. Overall, our findings provide evidence for a rather low influence of the APOE genotype on the hepatic stress response processes investigated in this study. PMID:27130033

    Cytochrome b(5) (cyt b(5)), a component of endoplasmic reticulum membrane, plays a role in modulation of enzymatic activity of some cytochrome P450 (CYP) enzymes. The effect of apo-cytochrome b(5) on this enzymatic system has not been investigated in details, because preparation of cyt b(5) as a pure protein failed in many laboratories. In order to prepare the native apo-cytochrome b(5) in a large scale we utilized a protein with higher affinity toward the heme; the apo-myoglobin from the equine skeletal muscle. In the first step, we extracted heme moiety from the native myoglobin by butanone extraction. Than the effect of pH on spontaneous heme release from both proteins was investigated: purified rabbit cyt b(5) as well as equine skeletal muscle myoglobin. The prepared apo-myoglobin was incubated with the cyt b(5) and heme transfer was monitored as a shift of absorption maximum from 413 to 409 nm in pH varying between 3-6 (10 mM KH(2)PO(4), pH 3-6). Here, we obtained 43 mg of the equine skeletal muscle apo-myoglobin (43% yield). The optimal pH range for heme transfer from cyt b(5) into apo-myoglobin was between 4.2 and 5.

    The paper illustrates how one future of coal haulage previously considered a fantasy is now a realistically achievable goal. The Komatsu 930 E truck has a 320 t payload and can travel up to 40 mph. It has an optional noise attenuation package and incorporates a vehicle health monitoring system (VHMS). Modular Mining produces an IntelliMine{reg_sign} innovative mine management system that optimises performance of equipment and personnel throughout the mine via a global positioning system. Komatsu has considered incorporating this idea in its trucks to produce an &apos;autonomous&apos; truck but no date can be fixed for the possible introduction of such a truck. 4 photos.

    In the year 1996 the spheres of competence of several DLR-Institutes working in the areas of fluid dynamics, reaction kinetics, combustion, numerical methods and laser measuring techniques have been brought together while contributing to the internal DLR project &apos;combustion chamber modelling (BKM)&apos;, in order to proceed with the computational simulation of combustion processes in combustion chambers of gas turbines. The main issue was the development of a research code for numerical simulation of fluid flow in real combustion chambers. Here the development of computational models of physical and chemical processes was emphasized, among other processes the formation of soot was treated. Moreover, a worldwide outstanding database of measured data for the purpose of code validation has been created within the framework of the BKM project using the laboratory facilities of the DLR, which are in Germany unique for the experimental investigation of the various processes in combustion chambers of gas turbines. The project BKM is part of the specific DLR-programme &apos;energy&apos;. With the successful completion of the first phase of the project in 1998, a second project phase of three years (BKM II) has been launched at the beginning of 1999. Here the work of the first phase continued and new topics were tackled. The second phase of the project was partly founded by the DLR-programme &apos;aeronautics&apos;. (orig.)

    The contrast medium dose used in CT renal function analysis corresponds to about 1 ml/kg body weight at a measurement interval of 5 or 10 minutes. In the present study the dependence of &apos;CT clearance&apos; on dosage and time was examined in 12 healthy subjects. The amount of clearance was directly proportional to the employed contrast medium dose and to the length of the measurement interval. On account of the superior signal-to-noise ratio, the higher dose (1 ml/kg body weight) will continue to be prefered in future. The measurement interval can be limited to 10 minutes. (orig.).

  19. Simulation Studies of the Role of Reconnection in the &apos;&apos;Current Hole&apos;&apos; Experiments in the Joint European Torus

    Injection of lower-hybrid current drive into the current ramp-up phase of the Joint European Torus (JET) plasma discharges has been observed to produce an annular current distribution with a core region of essentially zero current density [Hawkes, et al., Phys. Rev. Lett. 87 (2001) 115001]. Similar &apos;&apos;current holes&apos;&apos; have been observed in the Japan Atomic Energy Research Institute (JAERI) Tokamak 60 Upgrade (JT-60U) plasma discharges with off-axis current drive supplied by the bootstrap current [T. Fujita, et al., Phys. Rev. Lett. 87 (2001) 245001]. In both cases, the central current does not go negative although current diffusion calculations indicate that there is sufficient noninductive current drive for this to occur. This is explained by the Multi-level 3-D code (M3D) nonlinear 2-D and 3-D resistive magnetohydrodynamic (MHD) simulations in toroidal geometry, which predict that these plasma discharges undergo n = 0 reconnection events--&apos;&apos;axisymmetric sawteeth&apos;&apos;--that redistribute th e current to hold its core density near zero. Unlike conventional sawteeth, these events retain the symmetry of the equilibrium, and thus are best viewed as a transient loss of equilibrium caused when an iota = 0 rational surface enters the plasma. If the current-density profile has a central minimum, this surface will enter on axis; otherwise it will enter off-axis. In the first case, the reconnection is limited to a small region around the axis and clamps the core current at zero. In the second case, more typical of the JET experiments, the core current takes on a finite negative value before the iota = 0 surface appears, resulting in discrete periodic axisymmetric sawtooth events with a finite minor radius. Interpretation of the simulation results is given in terms of analytic equilibrium theory, and the relation to conventional sawteeth and to a recent reduced-MHD analysis of this phenomenon in cylindrical geometry [Huysmans, et al., Phys

    Apolipoprotein E4 (ApoE4) is a risk factor for Alzheimer's disease (AD). Whether this risk arises from a deficient function of E4 or the lack of protection provided by E2 ir E3 is unclear. Previous studies demonstrate that deprivation of folate and vitamin E, coupled with dietary iron as a pro-oxidant, for 1 month displayed increased PS-1 expression, gamma-secretase and Abeta generation in mice lacking ApoE (ApoE-/- mice). While ApoE-/- mice are a model for ApoE deficiency, they may not refle...

    Full Text Available Abstract Background The toxic and inflammatory potential of 5 different types of nanoparticles were studied in a sensitive model for pulmonary effects in apolipoprotein E knockout mice (ApoE-/-. We studied the effects instillation or inhalation Printex 90 of carbon black (CB and compared CB instillation in ApoE-/- and C57 mice. Three and 24 h after pulmonary exposure, inflammation was assessed by mRNA levels of cytokines in lung tissue, cell composition, genotoxicity, protein and lactate dehydrogenase activity in broncho-alveolar lavage (BAL fluid. Results Firstly, we found that intratracheal instillation of CB caused far more pulmonary toxicity in ApoE-/- mice than in C57 mice. Secondly, we showed that instillation of CB was more toxic than inhalation of a presumed similar dose with respect to inflammation in the lungs of ApoE-/- mice. Thirdly, we compared effects of instillation in ApoE-/- mice of three carbonaceous particles; CB, fullerenes C60 (C60 and single walled carbon nanotubes (SWCNT as well as gold particles and quantum dots (QDs. Characterization of the instillation media revealed that all particles were delivered as agglomerates and aggregates. Significant increases in Il-6, Mip-2 and Mcp-1 mRNA were detected in lung tissue, 3 h and 24 h following instillation of SWCNT, CB and QDs. DNA damage in BAL cells, the fraction of neutrophils in BAL cells and protein in BAL fluid increased statistically significantly. Gold and C60 particles caused much weaker inflammatory responses. Conclusion Our data suggest that ApoE-/- model is sensitive for evaluating particle induced inflammation. Overall QDs had greatest effects followed by CB and SWCNT with C60 and gold being least inflammatory and DNA-damaging. However the gold was used at a much lower mass dose than the other particles. The strong effects of QDs were likely due to Cd release. The surface area of the instilled dose correlated well the inflammatory response for low toxicity particles.

    Although the role of the breast cancer gene 2 (BRCA2) tumor suppressor gene is well established in inherited breast and ovarian carcinomas, its involvement in sporadic disease is still uncertain. The recent identification of a novel BRCA2 binding protein, EMSY, as a putative oncogene implicates the BRCA2 pathway in sporadic tumors. Furthermore, EMSY&apos;s binding to members of the &apos;Royal Family&apos; of chromatin remodeling proteins may lead to a better understanding of the physiological function of BRCA2 and its role in chromatin remodeling

    Full Text Available Biomarkers are the only feasible way to detect and monitor presymptomatic Alzheimer's disease (AD. No single biomarker can predict future cognitive decline with an acceptable level of accuracy. In addition to designing powerful multimodal diagnostic platforms, a careful investigation of the major sources of disease heterogeneity and their influence on biomarker changes is needed. Here we investigated the accuracy of a novel multimodal biomarker classifier for differentiating cognitively normal (NC, mild cognitive impairment (MCI and AD subjects with and without stratification by ApoE4 genotype. 111 NC, 182 MCI and 95 AD ADNI participants provided both structural MRI and CSF data at baseline. We used an automated machine-learning classifier to test the ability of hippocampal volume and CSF Aβ, t-tau and p-tau levels, both separately and in combination, to differentiate NC, MCI and AD subjects, and predict conversion. We hypothesized that the combined hippocampal/CSF biomarker classifier model would achieve the highest accuracy in differentiating between the three diagnostic groups and that ApoE4 genotype will affect both diagnostic accuracy and biomarker selection. The combined hippocampal/CSF classifier performed better than hippocampus-only classifier in differentiating NC from MCI and NC from AD. It also outperformed the CSF-only classifier in differentiating NC vs. AD. Our amyloid marker played a role in discriminating NC from MCI or AD but not for MCI vs. AD. Neurodegenerative markers contributed to accurate discrimination of AD from NC and MCI but not NC from MCI. Classifiers predicting MCI conversion performed well only after ApoE4 stratification. Hippocampal volume and sex achieved AUC = 0.68 for predicting conversion in the ApoE4-positive MCI, while CSF p-tau, education and sex achieved AUC = 0.89 for predicting conversion in ApoE4-negative MCI. These observations support the proposed biomarker trajectory in AD, which postulates

    This report details the work undertaken by the WOC 8 Study Group 8.1 (methane emissions) in the triennium 1997 to 2000. The objective is to identify the major methane emission sources within the natural gas chain and to estimate from that the global methane emissions caused by the natural gas industry with a reasonable accuracy. Against the background of substantial uncertainties and insufficient data, a conservative approach has been adopted. The results presented in this report are based on a commonly agreed method using reasonable emission factors, on data provided by the operators inside the natural gas industry and on reliable data from literature. The total methane emissions caused by the gas industry world-wide were some 20,000 kt in 1995. This figure neither includes the methane emissions connected with the production of crude oil nor the methane emissions connected with associated gas which occurs during oil production and is not fed into a gas grid. More than half of the methane emissions can be attributed to three countries: USA, Canada and Russia, producing more than 50 % of the world natural gas. Related to the world&apos;s natural gas net production of approx. 79,000 PJ (net calorific value) the specific methane emission is approx. 0.26 kt/PJ (0.92 g/kWh). (Assuming - as a &apos;worst case&apos; scenario - that natural gas is purely methane, a specific emission factor of 0.92 g/kWh corresponds to a leakage rate of 1.3 %). (author)

    From point of view of the health of human the most interesting persistent organic pollutants (POP) are the polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in the nutrition, in the case of the Baltic Sea, first and foremost in the fish. It is expected that the people living close to the Baltic Sea receive 63-83% of the total PCDD/Fs from the fish. The concentrations of dioxins in the samples of herring (Clupea harengus membras) and sprat (Sprattus sprattus), analyzed in the year 2002, did not exceed the limits, established by the European Union, as a rule. The only exception was herring older than six years, caught from the open part of the Baltic Sea. In this sample the dioxin level was 4.5 pg TEQ/g wet weight. As there is limited information, concerning the dioxin and &apos;&apos;dioxin like PCBs&apos;&apos; level in the perch (Perca fluviatilis), in 2003 the aforementioned fish was caught for analysis and a spatial evaluation in the Gulf of Riga (Paernu Bay).

    The delta phalanx, also known as the delta bone, or longitudinal epiphyseal bracket (LEB), has been described in a variety of syndromes and dysplasias. However, the &apos;&apos;kissing delta phalanx&apos;&apos; is not as well recognized in the literature; it consists of a duplicated longitudinal bracketed epiphysis, or a complex of two adjacent delta bones, with opposing convex portions facing each other. Magnetic resonance imaging of the kissing delta phalanx has not been previously described. To describe the evolution, variation and associated osseous anomalies of the kissing delta phalanx in three patients with distinct distal limb malformations using both plain films and magnetic resonance imaging. Patient 1 had Rubinstein-Taybi syndrome and, in addition to a kissing delta phalanx in both feet, had corresponding delta metatarsals (MT1). Patient 2 had Cenani-Lenz syndactyly with distinct variation of the kissing delta phalanx in each hand. He had a disorganized appearance to the phalanges, metacarpal fusions and carpal coalitions. Patient 3 had an isolated oligosyndactyly of the left hand with metacarpal fusions and carpal coalitions. All three patients were followed over time. We describe two types of kissing delta phalanges: separated (without fusion of the corresponding epiphyseal brackets) and nonseparated (with fusion of the corresponding epiphyseal brackets). Both types can be seen in the same patient and are a reflection of the relative degree of segmentation of the two delta bones. (orig.)
