    One of the objectives of endodontic treatment is to resolve pathological periapical processes caused by microbial contamination of the dental pulp. Correct execution of the necessary chemical preparation prior to surgery generally results in positive outcomes. However, a percentage of cases do not respond favorably and therefore require retreatment, a conservative therapeutic option. There are meanwhile a number of treatment failures which do not respond to these conservative measures and must therefore be subjected to paraendodontic surgical procedures. One of the principal problems of this therapeutic conduct is linked to the surface permeability of the dentin after apicoectomy and the lack of adequate marginal adaptation between the retrofilling material and the cavity walls. This permits the percolation of microorganisms and their metabolic by products from the system of root canals to the periapical region, thereby compromising the necessary tissue repair. The present work proposes the evaluation of the surface and marginal permeability of cut dentin after apicoectomy and treatment with Er:YAG and Nd:YAG lasers with fiber optics and then retrofilled with intermediate restorative material (IRM). A total of 24 single rooted teeth whose canals were endodontically treated were divided into 3 experimental groups: group I, whose apices were sectioned with an Er:YAG laser and the resulting cavity and the cut dental surface were irradiated with this laser via a 50/10 type fiber; in group II the apicoectomy was conducted with an Er:YAG laser and the resulting cavity and the cut surface were irradiated with a Nd:YAG laser; in group III, the samples were apicoectomized and the cavities were treated with a high speed bur (control group). Analysis of the infiltration of the dye methylene blue throughout the cut dental surface and the reconstruction demonstrated that the samples in the irradiated groups presented lower indices of infiltration than the control group. The Group I samples, meanwhile, did not present statistically significantly better results than the control group. Group II presented statistically significantly less infiltration than the other experimental groups. This result is compatible with the morphological and structural alterations evidenced by scanning electron microscopy: the group I samples (Er:YAG) presented clean, irregular surfaces with the presence of some cratering, without a smear layer and with the dental tubules exposed. The group II samples (Er:YAG and Nd:YAG) presented smoother, clean surfaces, without a smear layer, with fusion and resolidification of the dentin which sealed the dental tubules. Under the conditions of the study, apicoectomy with the Er:YAG laser followed by subsequent treatment of the cut surface and resulting cavity with a Nd:YAG laser, have shown as an option capable of reducing the permeability of the dentin to methylene blue dye.

    Objective: To evaluate the changes in clinical parameters and in the approach to patients submitted to radioiodine therapy for Graves' disease. Materials and methods: Dossiers of 226 patients submitted to radioiodine therapy for Graves' disease in the period between January 1990 and December 2001 were retrospectively evaluated. For the purposes of statistical analysis, the 12-year period was subdivided into three periods of 4 years, with a comparison of clinical and laboratory variables in these periods. Results: The authors have observed that the total number of patients referred for radioiodine therapy as well as the percentage of female patients presented a significant increase (from 62% to 86%; p = 0.005). The percentage of patients pretreated with methimazole before radioiodine therapy increased significantly (from 9.1% to 35.6%; p = 0.03). The mean radioiodine dose delivered has also presented a significant increase (from 7.6 mCi to 12.7 mCi; p = 0.000003) with a direct reflection on a higher percentage of patients cured one year after the radioiodine therapy (from 55.6% to 83.7%; p = 0.004). Conclusion: Radioiodine therapy has increasingly been accepted for treatment of patients with Graves' disease and the doses delivered have increased to achieve a permanent cure as well as a reduction of the chances of recurrence.

    Assuming the systems planning radiotherapy recognize all body structures of the same density (d=1 g/cm³), variations in electron density within the irradiated area, as is the case of patients who undergo reconstruction mammary processes and use tissue expanders, may influence the dose distribution in the treatment and may produce heterogeneities which are not measured by changing its actual distribution into healthy tissues or in the target volume to be irradiated. Through the calculation of the algorithms' dose distribution of the XiO® planning system (Fast Fourier Transform, Convolution, Superposition, Fast Superposition e Clarkson), when using correction of heterogeneity between tissues of different densities, there was obtained a percentage ratio of dose increase in the structures of interest, and of the amount of absorbed dose by healthy organs adjacent to the target volume.

    Full Text Available Foi empregue o niridazol um derivado do nitrotiazol, em doze pacientes com leishmaniose tegumentar americana. Em todos êles, o diagnóstico clínico da doença foi confirmado pela biópsia das lesões e em oito dêles também pela positividade da intradetermorreação de Montenegro. Oito pacientes tinham lesões mucosas metastáticas em atividade e lesões cutâneas iniciais cicatrizadas há tempo mais ou menos longo. Dois apresentavam concomitância de lesões cutâneas e mucosas em atividade, e dois tinham lesões cutâneas exclusivas. A duração da doença variou de 2 meses a 32 anos. A posologia diária do niridazol foi uniformememente de 25 mg/kg de pêso corpóreo. O medicamento foi administrado por via oral, em duas tomadas diárias, sempre com o doente internado em hospital. Quando a tolerância o permitia, o paciente recebia cinco séries de tratamento de 10 dias de duração cada, intercaladas por períodos áe suspensão da droga de 10 dias entre uma série e outra. Isso foi possível em 10 dos 12 pacientes. O tratamento foi bem tolerado em 5 doentes e de tolerância regular em 4. Mal tolerado em um paciente pela ocorrência de alucinações e excitação mental e interrompido pela péssima tolerância em dois doentes devido ao aparecimento de convulsões generalizadas com perda da consciência. O tratamento acompanhou-se de grande incidência, de efeitos colaterais. A ocorrência de para-efeitos mais intensos não foi devida às más condições hepáticas. Provas de função hepática. hemogramas, estudos bioquímicos do sangue e exames de urina, realizados antes, durante e após o tratamento, não revelaram alterações significativas. Biópsias hepáticas por punção com agulha em dez doentes, prévias e posteriores ao tratamento, não detectaram lesões hepáticas que pudessem ser atribuídas à medicação. O seguimento dos doentes prolongou-se pelo prazo de dois a 36 meses apos o tratamento. Alterações eletrocardiogr

  13. The strategic ''pull'' and operational ''push'' of total quality management in UK regional electricity service companies

    McAdam, R.; McLean, J.; Henderson, J.

    2003-04-30

    The aim of this paper is to evaluate whether the UK regional electricity companies (RECs) has used total quality management (TQM) as a ''push'' or as a ''pull'' change methodology. ''Push'' is the operational improvement role of TQM; ''pull'' 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 ''push'' and ''pull'' 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 ''push-pull'' 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 ''push''-based TQM activity that is driven by strategic or ''pull'' based TQM planning and activity. (author)

    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 ''HEDRad'' (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).

    During and after the treatment of cancer, people with HIV or transplants, the food intake can offer a well-being to the patient, because the action of eating right helps people to feel strong. Healthy people have their immune system working properly and can tolerate small amounts of bacteria. However, immunocompromised persons may not be able to and however immunocompromised people cannot fight this small amount of microorganisms and require a diet with very low microbiological count to avoid contact with potentially harmful bacteria. This is called neutropenic diet. These patients are susceptible to food contamination, so that it's not advisable the ingestion of raw products. The vegetable irradiation with low doses has the purpose of reducing the microbial load. The aim of this study was to obtain data on microbiological, sensorial e physicochemical aspects in minimally processed 'Primavera' salad irradiated with different doses of gamma radiation designed to immunocompromised patients. It were used doses of 1.0kGy, 2.0kGy, 3.0kGy and 4.0kGy irradiated in the Multipurpose Irradiator {sup 60}Co located in Radiation Technology Center. Microbiological analyzes were performed (n=25) using Petrifilm, sensory analysis using the sensory acceptance test (n=30) and triangular (n=15) and texture analysis (n=90) in the Food Microbiology Laboratory located at the Radiation Technology Center. The texture analysis was performed with the aid of a texturometer equipped with 5 kg load cell using a triangular cutting Warner-Bratzler Knife blade probe with the descent speed of 2mm/sec. All results were expressed in Newtons (N). The results showed that for microbiological analyzes the standards were followed according to the RDC 12/01 ANVISA. For the sensory test of acceptation no difference was found among the samples, however in the triangular test could be found slight differences between samples irradiated with 4.0kGy and control and there was significant

  20. The ''invisible'' radioactive scale

    1999-04-01

    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 ''unsupported'' 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.

    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 ''green''. Here we present data on the development of a green demulsifier for Statoil's Gullfaks ''A'' platform, which not only meets the very stringent regulations but also exhibits a significant improvement in product performance. While the''bottle test'' remains the industry standard method for selecting demulsifiers, in recent years the ''mini trial'' 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)

    France is a nuclear power nation. And this is not going to change. However, at the same time, the country is also pursuing massive investments in the expansion of renewable energies. According to France's President Nicolas Sarkozy, the motto should be: 'side-by-side' rather than 'one or the other'. For the PV sector, whose success was unbroken during the crisis in 2009, the signal is positive and could mean sustained growth. (orig.)

Assim sua ocorrência no sexo masculino é quase que exclusiva, devido o homem apresentar somente um cromossomo X. A gravidade da doença pode variar em severa, moderadamente severa e leve, após dosagem dos fatores VIII e IX da coagulação. Uma das complicações mais temíveis dos pacientes com esta doença refere-se ao desenvolvimento de inibidores, que são anticorpos direcionados contra os fatores infundidos. O diagnóstico da doença é realizado através de exames laboratoriais, principalmente pelo coagulograma completo e dosagem de fatores específicos, baseando-se nas manifestações clínicas apresentadas pelo paciente. A hemofilia não tem cura e a base do seu tratamento é a infusão do concentrado do fator deficiente. No entanto, pacientes podem desenvolver inibidores específicos para os fatores infundidos e, nestes casos as alternativas de tratamento são o uso da biotecnologia para novos medicamentos e o uso da terapia gênica

    Full Text Available O tratamento antidepressivo deve ser realizado considerando os aspectos biológicos, psicológicos e sociais do paciente. Na média, não há diferenças significativas em termos de eficácia entre os diferentes antidepressivos mas o perfil em termos de efeitos colaterais, preço, risco de suicídio, tolerabilidade varia bastante o que implica em diferenças na efetividade das drogas para cada paciente. A conduta, portanto, deve ser individualizada. A prescrição profilática de antidepressivos irá depender da intensidade e freqüência dos episódios depressivos. O risco de suicídio dever ser sempre avaliado e se necessário o ECT deverá ser indicado. Não há antidepressivo ideal, entretanto, atualmente existe uma disponibilidade grande de drogas atuando através de diferentes mecanismos de ação o que permite que, mesmo em depressões consideradas resistentes, o tratamento possa obter êxito.The antidepressant treatment should be accomplished considering the patient’s biological, psychological and social aspects. In average, there are no significant differences in terms of efficacy among the different antidepressants but the profile in terms of collateral effects, price, suicide risk, tolerability shows great variation which implies in differences in the effectiveness of drugs for each patient. The therapy, therefore, should be individualized. The prophylactic prescription of antidepressants will depend on the intensity and frequency of the depressive episodes. The suicide risk should always be evaluated and if necessary ECT should be prescribed. There is no ideal antidepressant, however, there is a large variety of drugs acting through different mechanisms of action which allows the possibility of therapeutic success in resistant depressions.

    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 ''positive'' 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 (''negative feedback''), but also triggering star formation by outflow induced pressure at the edges (''positive feedback''). XID2028 represents the first example of a host galaxy showing both types of feedback simultaneously at work.

  11. Switzerland as Europe's ''battery''. 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 ''Europe's battery'', 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's hopes for a role as a major European electricity storage provider appear somewhat exaggerated even in the long-term perspective.

  12. ApoE polymorphisms in narcolepsy

    2001-08-01

    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.

  13. ''When Cost Measures Contradict''

    Energy Technology Data Exchange (ETDEWEB)

    Montgomery, W. D.; Smith, A. E.; Biggar, S. L.; Bernstein, P. M.

    2003-05-09

    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'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'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.

    ''The Build'' 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 ''the build.'' 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 ''perceived'' 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 ''weighing'' 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 ''Eris'', 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} ''Via Lactea II'' (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 ''cold veil'' 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 ''heavy'' 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 ''light'', centrally concentrated MW halo.

    International Nuclear Information System (INIS)

    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. Most of other nuclear countries are currently rethinking their used fuel management, taking into account; the geopolitical context and the international framework, including multilateral agreements, the legacy of their past fuel cycle policies,the cornerstones of energy policies' evolution such as the targets set for energy independence, as well as the level of their ambition in terms of nuclear park evolution, the involvement of concerned stakeholders in the decision making process, the regulatory and legal frameworks evolutions, the operational challenges that the nuclear actors are currently facing, in particular the increasing Constraints related to reactor pool storage, or to very long term dry storage. With the foreseen nuclear development, the used fuel backlog will continue to grow for several decades. Bolstered by a 40 years experience, recycling has been contributing to further increase safety while offering main operational, environmental, global acceptance benefits, among others However even though recycling

    The distinctive cometary X-ray morphology of the recently discovered massive galaxy cluster ''El Gordo'' (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 ''bullet'' leads a ''twin-tailed'' wake, with the Sunyaev-Zel'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 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' 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'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 ''social capitalism'' as expressed in it's recurrent Five Year National Plans since 1999, the national government and all the provinces have programs, unlike many western and industrialized nations, to ''plan'' 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 ''encouraging foreign investment industries''. The key part of the law is to guarantee long-term power purchase agreements with state owned and controlled ''utilities''. 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 ''lessons'' 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 ''major'' and ''minor'' sutures of the four ''sutural arches'' 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 ''major'' but also to ''minor'' 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 ''major'' and ''minor'' 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.)

    In the Spring of 2001, the National Research Council published ''Disposition of High-Level Waste and Spent Nuclear Fuel: The Continuing Societal and Technical Challenges.'' (1) While finding the technical case for deep geologic disposal of high-level waste and spent fuel robust, the report focused new attention on societal issues and decision-making. The report appeared against a backdrop of heightened controversy about the development of a geologic repository at Yucca Mountain, Nevada. This paper identifies three principal reasons for the National Research Council committee's finding that ''Difficulties in achieving public support have been seriously underestimated in the past, and opportunities to gain public trust have been missed.''

    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.

    Full Text Available Estudo realizado em Porto Velho (RO, junto a doentes de tuberculose que interromperam o tratamento. A partir da abordagem qualitativa e do método hermenêutico-dialético de análise do material das entrevistas, foi possível inferir que os sujeitos deste estudo têm pouco conhecimento sobre tuberculose e tomam atitudes relacionadas ao impacto que o diagnóstico e o tratamento prolongado causaram a eles próprios e ao seu meio social. Para os doze entrevistados, a interrupção do tratamento relaciona-se a motivos enraizados no não-dito, efeitos colaterais dos medicamentos, desorganização dos serviços e ilusão de estar curado. Isto implica repensarmos nossas posições técnico-metodológicas e as relações profissional-doente, visando a uma abordagem que possibilite encararmos tuberculose-interrupção de tratamento como experiências vividas pelas pessoas, famílias e redes sociais por elas tecidas ao longo do tempo.

    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.)

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    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

    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 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.

    This agreement, discussed between the French government and Electricite de France (EdF) group, proposes some engagements for the 2001-2003 era for a better environmental integration of power transmission and distribution networks. The agreement is made of two parts: 1 - public distribution networks: realization of new workmanship (medium and low voltage power lines, new lines in dense urban areas), actions on existing workmanship (consequences of December 1999 storms, aesthetical aspects, burial of the main overhead lines in wooded areas, reinforcement of EdF&apos;s environmental commitment, remedial actions for environmental &apos;black points&apos;), general measures of implementation (increasing network safety, protection of birds fauna, coordination of works); 2 - public transportation network (RTE): development and safety improvement of the public transportation network (reinforced arrangement for the establishment of regional development schemes, development of international interconnections, safety improvement of the public transportation network, RTE&apos;s environmental plan); line projects (arrangements during projects elaboration, accompanying program); long lived RTE&apos;s commitment (environmental management and ISO-14001 certification, vigilance with respect to electromagnetic fields, R and D).

    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.

  11. &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.)

  14. High energy X-ray laboratory &apos;'HEXYLab'&apos;. The new facility &apos;'HEXYTech'&apos;

    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).

  16. 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.

Essa neoplasia ocorre devido à mutação do gene KIT com consequente ativação constitutiva da proteína KIT. O tratamento primário é cirúrgico e consiste na sua ressecção completa. Entretanto, alguns grupos de pacientes apresentam risco elevado de recorrência mesmo após operação com ressecção completa (R0, indicando diferenças no comportamento biológico. Estudos clínicos comprovaram a atividade clínica do mesilato de imatinibe, fazendo dele a primeira linha de tratamento padrão nos GISTs metastáticos ou irressecáveis, mudando muito o desfecho clínico dessa doença em relação aos benefícios anteriormente obtidos com a quimioterapia antineoplásica. MÉTODO: Foi realizada revisão da literatura com consulta nos periódicos das bases Medline/Pubmed, Scielo e Lilacs cruzando os descritores: tumor estromal gastrointestinal, Gist, tratamento, adjuvância. Além desta revisão foi adicionada a experiência pessoal dos autores. CONCLUSÃO: Melhor refinamento dos critérios de prognóstico tem permitido selecionar de forma mais adequada pacientes para o tratamento adjuvante com imatinibe. Os resultados de maior evidência até o momento respaldam o tratamento adjuvante por um ano, o que produz benefício significativo na sobrevida livre de recidiva, mas não na sobrevida global desses pacientes.INTRODUCTION: Gastrointestinal stromal tumor (GIST is the most common sarcoma of the digestive tract.

    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 Pacientes com transtornos alimentares possuem inadequações profundas no consumo, padrão e comportamento alimentar, além de diversas crenças equivocadas sobre alimentação, o que geralmente acarreta piora do estado nutricional. O tratamento nutricional visa a reverter tais alterações e promover hábitos alimentares saudáveis e melhor relação para com o alimento. Os objetivos e características do tratamento diferem para a anorexia nervosa e a bulimia nervosa, contudo, usualmente, a abordagem é dividida em duas fases: a educacional, cujas principais metas são a regularização do hábito alimentar e o aumento do conhecimento nutricional, e a experimental, que visa a propiciar maior reabilitação nutricional e mudanças mais profundas no comportamento alimentar. As evidências existentes sugerem que o tratamento nutricional promove a melhora de tais parâmetros, porém, alguns comportamentos alimentares, como a sensação de incompetência ao lidar com os alimentos, permanecem. Desta forma, mais estudos são necessários para que se possa de fato avaliar a eficácia da abordagem nutricional.Patients with eating disorders have disturbed food intake, food pattern, food behavior, and mistaken beliefs about food and nutrition, which can worsen nutritional status. The nutritional treatment aims to revert such alterations and to promote better food habits and relationship with food. The objectives and characteristics of the treatment are different for anorexia nervosa and bulimia nervosa, but usually the approach has two phases: the educational phase, whose major goals are regularization of food habits and increase of nutrition knowledge; and the experimental phase, whose targets are better nutritional rehabilitation and more complex improvements of nutritional behavior. Evidence suggests that nutritional treatment can ameliorate such parameters, but some inadequate food behaviors remain, such as feeling of incompetence while dealing with

    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.

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

Drogas acessórias são anticolinérgicos, úteis para o tremor; amantadina, para bradicinesia e rigidez; e agonistas dopaminérgicos que ajudam no manuseio de complicações da levodopa. A selegelina tem discreta ação sintomática e possível ação neuroprotetora. O tratamento de DP pode ser complicado por falha primária, falha secundária e problemas do uso da levodopa. A falha primária pode ser causada por uso de agentes antidopaminérgicos, presença de tremor de repouso severo ou erro diagnóstico. A causa mais comum de falha secundária é progressão da DP. As principais complicações do uso da levodopa são flutuações e discinesias. Outros problemas comuns são disautonomia, depressão, psicose e demência. Fenomenologia e manuseio destas complicações são discutidos. Perspectivas futuras incluem cirurgias para reversão de patologia.

    Full Text Available RESUMO A papilomatose é uma doença de natureza crônica e pode causar tumores epiteliais e na mucosa. Não possui predileção por sexo, raça ou idade, mas comumente aparece em animais jovens. As lesões papilares ocorrem principalmente na mucosa bucal, nos lábios, língua e da faringe, além destes, também são encontradas na forma ocular e cutânea. Este estudo teve como objetivo relatar a eficácia da Thuya occidentalis CH12, uma medicação homeopática de uso comum, no tratamento de cães com papilomatose. Os resultados positivos puderam ser vistos, em alguns casos, já na primeira semana do tratamento, em outros, após vinte dias, e o desaparecimento total das lesões, na maioria dos casos, ocorreu com quinze dias. Alicerçada no princípio da similitude, a homeopatia apóia-se na observação experimental de que toda substância capaz de provocar determinados sintomas em uma pessoa sadia, é capaz de curar estes mesmos sintomas em uma pessoa enferma. A Thuya occidentalis provou ser eficiente contra lesões de papilomavírus canina, e apresentou resultados rápidos e com um valor econômico acessível.

    Full Text Available A retinopatia diabética é a causa mais frequente de cegueira na população ativa nos países desenvolvidos. A prevalência da retinopatia diabética aumenta com a duração da diabetes, e praticamente 100% dos pacientes com diabetes tipo I (DM I e mais do que 60% dos pacientes com o tipo II (DM II apresentarão algum sinal de retinopatia após 20 anos. Além de um controle sistêmico rigoroso dos níveis glicêmicos, lipídicos, colesterol e da pressão arterial, o exame oftalmológico de rotina, com a identificação precoce da retinopatia diabética, podem detectar anormalidades em estágios primários, o que possibilita o tratamento ainda na fase inicial do problema; o uso adequado da fotocoagulação e a utilização da terapia antiangiogênica pode reduzir o número de pacientes com hemorragia vítrea ou descolamento tracional da retina. Infelizmente, em vários pacientes, a retinopatia progride mesmo com as melhores condutas tomadas pelo paciente e pelo oftalmologista, embora vários olhos podem se beneficiar com o tratamento cirúrgico, a vitrectomia posterior via pars plana. Esta revisão apresenta as indicações atuais para cirurgia vitreorretiniana em pacientes portadores de retinopatia diabética proliferativa.

    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.

  15. Optimal &apos;'image-based'&apos; weighting for energy-resolved CT

    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.

    The grading of clean rooms is performed according to precise criteria depending on the intended purpose of the rooms. Validation of this grading is different depending on the country. In this paper, the author proposes a synthesis of the different technical points which can give help in making a choice: grading families (particulates, biological hazards, risks, good manufacturing practices, contamination kinetics, air-flow), validation of grading (French and foreign standards, &apos;as built&apos;, &apos;at rest&apos; and &apos;operational&apos; grading), grading based on particulates (different classes, choice for a given class, consistency between definitions, extra-grading), grading based on microorganisms (efficiency of filters), grading based on air flow (integral or partial laminar flow, turbulent flow), grading based on air flow rates (different types of air, mixing ratio, new air inflow ratio).

    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.)

    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.

  5. OBJECTIVE BAYESIAN ANALYSIS OF &apos;'ON/OFF'&apos; MEASUREMENTS

    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.

  6. 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.

    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

    Full Text Available Objetivo: avaliar as complicações perinatais decorrentes da associação de asma e gravidez em pacientes que necessitaram hospitalização para controle da crise asmática. Método: análise retrospectiva de 12 casos de asma e gravidez que necessitaram de internação hospitalar e foram assistidos no Departamento de Ginecologia e Obstetrícia da Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, no período compreendido entre 1992 e 1996. Os parâmetros analisados foram: idade materna, acompanhamento pré-natal, tempo de permanência hospitalar, tratamento instituído, intercorrências gravídicas, idade gestacional ao parto, tipo de parto, peso ao nascer e índice de Apgar. Resultados: das 12 gestantes asmáticas, 7 não haviam iniciado o seguimento pré-natal antes da internação para o tratamento da crise asmática. Três pacientes apresentaram doença hipertensiva específica da gravidez, sendo um dos casos associado a rotura prematura de membranas e corioamnionite e outro associado a descolamento prematuro de placenta. Foram diagnosticados 2 casos de insuficiência placentária, um deles associado a trabalho de parto prematuro e transfusão feto-fetal em gestação gemelar e outro associado a oligoâmnio. Foi detectado 1 caso de oligoâmnio associado a pneumonia materna e óbito fetal e também 1 caso de polidrâmnio. Além disso, ocorreram 2 casos de parto prematuro e 3 recém-nascidos foram considerados pequenos para a idade gestacional. Conclusões: a prevenção das complicações da asma na gravidez deve ser instituída antes mesmo da concepção, enfatizando-se os aspectos educativos da paciente em relação à doença e afastando-se quando possível os fatores desencadeantes das crises, como os alergênios ambientais e o tabagismo. O tratamento deve ser instituído precocemente e a paciente deve ser acompanhada em conjunto pelo obstetra e pelo pneumologista.Purpose: to study perinatal outcome in asthmatic

    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.)

    Full Text Available Acromegalia é uma doença debilitante e desfigurante que, se não controlada adequadamente, reduz a expectativa de vida do paciente. Complicações cardiovasculares e respiratórias representam as principais causas de morte nos acromegálicos. Atualmente, o diagnóstico é realizado de acordo com as diretrizes do consenso de 2000: ausência de supressão do GH para um valor <1ng/mL e IGF-1 elevado. Avanços em todas as modalidades terapêuticas têm ocorrido, propiciando o controle bioquímico da doença em um número cada vez maior de pacientes. Estudos prévios mostraram que a obtenção de níveis seguros de GH (GH médio <2,5ng/mL e de IGF-1 normal reduz a taxa de mortalidade para o normal. Em 2002, foram publicadas diretrizes para o manejo da acromegalia, o qual envolve, muitas vezes, uma abordagem multidisciplinar. Neste artigo, fazemos uma avaliação crítica do que dispomos no Brasil para seguirmos as diretrizes estabelecidas nos consensos sobre diagnóstico e tratamento da acromegalia.

    &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)

    Full Text Available A model of acute schistosomiasis of the mouse was used to observe whether curative treatment would be followed by an enhancement of the hepatic and splenic lesions, as a consequence of the massive destruction of worms and eggs within the portal system. Mice infected with 50 cercariae of Schistosoma mansoni were treated with both oxamniquine and praziquantel on the 50th day of infection and submitted to a sequential histologic examination from the 2nd to the 45th day after treatment. Although severe focal lesions due to dead and disintegranting worms were present in the livers of the treated animals, no aggravation of the general changes (reative hepatitis and splenitis, or periovular granulomas was seen in comparison with a control non-treated group. Of 50 animals treated during the acute phase of schistosomiasis only one died espontaneously, while 16 ou of 30 infected controls died before the end of the experiment. The present investigation indicates that curative treatment during the acute phase of schistosomiasis does not enhance previous lesions at first and results in progressive disappearance of the lesions starting six days following chemotherapy.Foi utilizado um modelo de esquistossomose aguda do camundongo para testar se o tratamentop curativo da parasitose nesta fase poderia produzir uma exacerbação das lesões hepáticas e esplênicas, em virtude da destruição maciça de vermes e ovos nointerior do sistema porta.

Corticosteróides e imunossupressores vêm sendo utilizados na prática clínica diária com resultados nem sempre animadores. Apesar de não haver estudos controlados que abordem o tratamento da AT, diferentes estudos observacionais descrevem a resposta de pacientes com AT ao uso de corticosteróides, metotrexato (MTX, azatio-prina e ciclofosfamida. Após a introdução da terapia biológica, novas perspectivas têm surgido para os pacientes com AT refratários aos esquemas terapêuticos tradicionais.Takayasus’s arteritis is a chronic granulomatous vasculitis involving the aorta and its main branches. Monitoring disease activity and the choice for the best therapy has been major challenger faced by all physicians who treat these patients. Corticosteroids and immunosuppressive therapy have been used in daily medical practice, but results have not always been encouraging. Although there are no controlled studies evaluating the treatment of Takayasu’s arteritis, observational studies have described the response to the use of corticosteroids, methotrexate, azathioprine and cyclophosphamide. The emerging of biological therapy has brought new perspective for Takayasu’s patients who are refractory to conventional therapy.

    Full Text Available Admitindo que as populações de insetos crescem segundo a lei logística, o autor, partindo de uma equação que a descreve, apresenta uma fórmula que permite estabelecer o intervalo de tempo que deve decorrer entre os tratamentos inseticidas, para que a infestação por uma praga não exceda um limite pré-estabelecido. O valor de t (intervalo, expresso em número de gerações do inseto depende do potencial biótico da espécie, da eficiência do inseticida e do nível de infestação que se estabelecer como máximo permissível. Os resultados teóricos são discutidos e mostram a possibilidade de sua comprovação por meio de populações de insetos mantidas em laboratório, como fase preliminar à sua aplicação no campo.Based on the assumption that the growth of insect populations follows the logistic law, the author developed an equation for the determination of the time interval between insecticide treatments: t= {lpg [100-Po (1-E / (1 - E (100 -Po]} / log p where t = time interval between treatments expressed in number of generations of the species; Po = maximum percentage of infestation, that must not be surpassed (from 0,00 to 100,00; E = efficiency of the insecticide (from 0,00 to 1,00; p = reproduction potential of the species.

    Full Text Available Leiomiomas são tumores benignos. Eles surgem no miométrio e contêm quantidade variável de tecido conjuntivo fibroso. Cerca de 75% dos casos são assintomáticos, encontrados ocasionalmente durante exame abdominal, pélvico bimanual ou ultra-sonografia. Os sintomas são relacionados diretamente ao tamanho, ao número e à localização dos miomas. Nessa revisão, são apresentadas as abordagens terapêuticas atuais clínicas (anticoncepcionais orais, progestágenos e antiprogestágenos, análogos do hormônio liberador das gonadotrofinas (GnRH, e antiinflamatórios não esteróides e cirúrgicas (histerectomia, miomectomia e embolização para o tratamento de leiomiomas.Leiomyomas are benign tumors.

    Full Text Available A cisticercose, um dos mais sérios problemas parasitológicos do sistema nervoso, apresenta, quando localizada na fossa posterior, um quadro clínico dramático, no qual predomina a hipertensão intracraniana. Foram estudados neste trabalho, 70 pacientes com cisticercose de fossa craniana posterior, atendidos no Serviço de Neurocirurgia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo de 1945 a 1968. Considerando-se a grande diversidade existente em torno das técnicas de tratamento cirúrgico, foi objetivo deste trabalho o estudo dos resultados obtidos nestes pacientes, nos quais várias técnicas foram empregadas. As cirurgias paliativas que derivam o trânsito do líquido cefalorraqueano para regiões extracranianas, quando comparadas aos outros tipos de cirurgias utilizados, foram as que proporcionaram maior índice de recuperação, exigiram menos reoperações, além de terem sido acompanhadas de menor número de complicações, bem como de menor mortalidade pós-operatória. Por outro lado, a neurocisticercose geralmente é um processo difuso, encontrando-se parasitas em várias regiões do encéfalo e/ou aracnoidite, conforme comprovou-se, também, entre os casos ora reunidos e que vieram a falecer. Baseando-se nestes fatos, não se justificam as derivações intracranianas e, a não ser eventualmente, a abordagem direta do parasita. Os casos estudados permitem cone- tatar, portanto, que as derivações extracranianas, por sua simplicidade e eficácia, apresentam-se, atualmente, como a terapêutica cirúrgica mais propriada à cisticercose de fossa craniana posterior.

  2. 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

    In the food industry, injuries due to food poisoning have been increasing. Especially the mass outbreak of food poisoning by Escherichia coli such as O-157 in 1996 gave warning on the importance of food sanitation management. Public efforts such as the Hazard Analysis and Critical Control Point (HACCP) system have been made to prevent food poisoning. Recently, disinfection made by electrolyzing water with some salt added has attracted attention. Fuji Electric has developed the generator &apos;SaniBoy&apos; that produces weak alkaline electrolyzed water without wasting water. The environment-friendly &apos;SaniBoy&apos; will contribute to sanitation in various fields. (author)

    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.

  16. 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

  17. Improvement in remote sensing of low vegetation cover in arid regions by correcting vegetation indices for soil &apos;'noise'&apos;

    International Nuclear Information System (INIS)

    The variations of near-infrared red reflectance ratios of ten aridic soil samples were correlated with a &apos;&apos;redness index&apos;&apos; computed from red and green spectral bands. 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

    Full Text Available RESUMO Objetivo: Determinar a estratégia mais custo-efetiva para o tratamento do glaucoma primário de ângulo aberto em fase inicial, comparando-se as seguintes alternativas: observação, tratamento clínico ou tratamento com laser. Métodos: Por meio de um modelo de Markov, sob a perspectiva do Sistema Único de Saúde (SUS e um horizonte da expectativa de vida média da população brasileira. Comparou-se a razão de custo-utilidade incremental (ICUR entre 3 alternativas de tratamento, assim como seus custos e o ganho em qualidade de vida, medido em QALY (Quality-adjusted life years. Resultados: A ICUR do tratamento inicial com laser e do tratamento inicial com colírios, em relação a não tratar foi de R$ 2.811,39/QALY e R$ 3.450,47/QALY, respectivamente. Ambas as estratégias foram custo-efetivas, com uma discreta vantagem para o tratamento a laser. Esta diferença diminui ainda mais quando se aumenta a idade de entrada no modelo. As duas alternativas propiciaram ganhos significativos de qualidade de vida (em torno de 2,5 QALYs para o tratamento com laser e de 5,0 QALYs para o tratamento com colírios. Conclusão: Tanto o tratamento primário com trabeculoplastia a laser quanto com medicações foram custo-efetivos e proporcionaram ganhos reais de qualidade de vida quando comparados com o não tratamento do GPAA.

    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.

    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.

    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.

    Full Text Available As duas abordagens terapêuticas mais estudadas para o tratamento da bulimia nervosa (BN são os tratamentos psicológicos, principalmente a terapia cognitivo-comportamental (TCC e o uso de antidepressivos. Os resultados de duas revisões sistemáticas da literatura mostram que a TCC é melhor que fila de espera e que os antidepressivos são superiores ao placebo na remissão a curto prazo dos sintomas bulímicos. A comparação direta das duas abordagens mostra que, quando usados como abordagens exclusivas, a TCC é clinicamente mais eficaz e mais aceita do que os antidepressivos. A associação dos dois tipos de tratamento é clinicamente mais eficaz que cada um isoladamente, mas a aceitação das abordagens psicológicas exclusivas é maior. Como a BN é um transtorno grave e com baixa taxa de remissão espontânea, o tratamento associado, com abordagem multidimensional e multidisciplinar, pode ser indicado.

    &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.

    From September 24th to 25th, 2014 the KRAFTWERKSSCHULE E.V. (KWS) held the congress &apos;&apos;Rueckbau 2014&apos;&apos;. 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.

  20. 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

    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.

O gasto médio mensal com medicamentos foi estratificado por faixas etárias e descrito de acordo com as características demográficas, clínicas e tipo de medicamento utilizado. Foi utilizado modelo de regressão linear para avaliar o impacto de características demográficas e clínicas sobre o gasto médio mensal per capita com os medicamentos. RESULTADOS: Foram identificadas 72.265 mulheres que receberam medicamentos para o tratamento da osteoporose na pós-menopausa. O gasto médio mensal per capita no primeiro ano de tratamento foi de R$ 90,00 (dp R$ 144,49. A maioria das mulheres tinha de 60 a 69 anos de idade, iniciaram tratamento em 2000, eram residentes na região Sudeste, tinham fraturas osteoporóticas prévias e o alendronato de sódio foi o medicamento mais utilizado no início do tratamento. A maioria das pacientes permaneceu em uso do mesmo princípio ativo durante o tratamento. Foram identificados 6.429 óbitos entre as participantes. Mais de um terço das mulheres permaneceram no programa por até 12 meses. Raloxifeno e calcitonina sintética foram as alternativas com maior impacto sobre o gasto médio mensal com medicamentos, tendo como padrão de referência o alendronato de sódio. CONCLUSÕES: Dado o alto impacto do tipo de medicamento utilizado no gasto com medicação, recomenda-se estabelecer critérios para prescrição e dispensação, com prioridade para aqueles com menores custos e maior efetividade.

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

    Energy Technology Data Exchange (ETDEWEB)

    Shahram, Chubin

    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.

  9. Phase equilibria in a system of &apos;breathing&apos; molecules

    2001-09-30

    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.

  12. 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.

The programme, achievements and perspectives of the refection group are summarised.

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

    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.)

    2010-04-01

    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.

    2012-09-15

    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.

Em ambos os casos houve normalização do hemograma em dois meses. Na associação ascaridíase/ancilostomíase também são possíveis dois tipos de comportamento da eosinofilia após tratamento eficaz: ou vai diminuindo a hipereosinofilia, logo em seguida à expulsão dos parasitos, ou há no primeiro mês um aumento da hipereosinofilia (geralmente mais acentuado na primeira semana que se segue ao tratamento, para diminuir após o fim do primeiro mês progressivamente até desaparecer. Na estrongiloidíase e na associação ascaridíase/estrongiloidíase há diminuição constante da hipereosinofilia logo após o tratamento e o hemograma se normaliza em cerca de dois meses. Na trieuríase, a hipereosinofilia, aliás já discreta, diminui pouco com o tratamento. Na ancilostomíase e na associação ancilostomíase/trieuríase a hipereosinofilia ou desce após o tratamento gradativo e lentamente, ou primeiro há uma exaltação temporária nas primeiras três semanas após a terapêutica, para diminuir em seguida.

  5. 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

  6. 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

    Full Text Available OBJETIVO: Avaliar a evolução pós-operatória de pacientes com divertículo faringoesofagiano submetidos aos tratamentos cirúrgico e endoscópico. MÉTODOS: Foram analisados de maneira retrospectiva 36 pacientes com divertículo faringo-esofagiano atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP. Os pacientes foram distribuídos em dois grupos, na dependência do tratamento: grupo 1 (n=24 - diverticulectomia associada á miotomia do cricofaríngeo, através de cervicotomia esquerda; grupo 2 (n=12 - diverticulostomia endoscópica usando grampeador linear. RESULTADOS: A mortalidade operatória foi nula em ambos os grupos. Complicações precoces: grupo 1 - dois pacientes desenvolveram fistula cervical e outros dois, rouquidão; grupo 2 - sem complicações. Complicações tardias: grupo 1 - sem complicações: grupo 2: recidiva da disfagia em quatro pacientes (p=0,01. O seguimento médio foi 33 meses para o grupo 1 e 28 meses para o grupo 2. CONCLUSÃO: Os dois procedimentos foram eficazes na remissão da disfagia. O tratamento cirúrgico apresentou superioridade em relação ao endoscópico, com resolução da disfagia com um único procedimento. O tratamento endoscópico deve ser reservado para os mais idosos e portadores de comorbidades.

    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.)

    Full Text Available O ligamento cruzado anterior (LCA é uma das estruturas que compõe a articulação do joelho. As lesões do LCA estão ocorrendo com frequência e está é suscetível a lesões em desportos de contato. A perda deste ligamento gera instabilidade anterior do joelho podendo limitar a capacidade funcional, sobrecarregar os estabilizadores secundários e limitar a atividade esportiva do individuo, assim a indicação cirúrgica no tratamento da lesão do LCA vem sendo um consenso. Desta forma, este estudo tem por objetivo apresentar variados protocolos de tratamento após cirurgia de reparação deste ligamento. Embora todos os protocolos encontrados foquem o mesmo objetivo de dar ao paciente as mesmas capacidades funcionais comparativamente ao membro não operado, neste estudo podemos concluir que as opções de tratamento são numerosos com relação as condutas fisioterápicas e os conhecimentos sobre patologias do joelho sofreram grande avanço e por consequência vários protocolos ainda vêm sendo desenvolvidos, e a recuperação do paciente deve sempre focar no objetivo e levar sempre em conta a profissão, o esporte, o estilo de vida e a idade do paciente na escolha do protocolo.

    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.)

  1. 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.)

  13. 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

    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.

Increased BDNF levels in the frontal cortex were observed in apoE2 mice compared to apoE3. These results underscore behavioral differences between...

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

    Directory of Open Access Journals (Sweden)

    Laurence O'Dwyer

    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.

    Full Text Available BACKGROUND: Endovascular approach to the aortic arch is an appealing solution for selected patients. OBJECTIVE: To compare the technical and clinical success recorded in the different anatomical settings of endografting for aortic arch disease. METHODS: Between June 1999 and October 2006, among 178 patients treated at our institution for thoracic aorta disease with a stent-graft, the aortic arch was involved in 64 cases. According to the classification proposed by Ishimaru, aortic zone 0 was involved in 14 cases, zone 1 in 12 cases and zone 2 in 38 cases. A hybrid surgical procedure of supra-aortic debranching and revascularization was performed in 37 cases. RESULTS: Zone 0. Proximal neck length: 44±6 mm. Initial clinical success was 78.6%: two deaths (stroke, one type Ia endoleak. At a mean follow-up of 16.4±11 months the midterm clinical success was 85.7%. Zone 1. Proximal neck length: 28±5 mm. Initial clinical success was 66.7%: 0 deaths, four type Ia endoleaks. At a mean follow-up of 16.9±17.2 months the midterm clinical success was 75.0%. Zone 2. Proximal neck length: 30±5 mm. Initial clinical success was 84.2%: two deaths (one cardiac arrest, one multiorgan embolization, three type Ia endoleaks, one case of open conversion. Two cases of delayed transitory paraparesis/paraplegia were observed. At a mean follow-up of 28.0±17.2 months the midterm clinical success was 89.5%. CONCLUSIONS: This study and a literature review demonstrated that hybrid procedure for aortic arch pathology is feasible in selected patients at high risk for conventional surgery. Our experience is still limited by the relatively small sample size. We propose to reserve zone 1 for patients unfit for sternotomy or in cases with aortic neck length > 30 mm following left common carotid artery debranching. We recommend to perform complete aortic rerouting of the aortic arch in cases with lesser comorbidities and shorter aortic neck.CONTEXTO: O tratamento endovascular

    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 %. The diagnostic sensitivity, specificity, and accuracy of CMR in patients with &apos;&apos;infarct-like myocarditis&apos;&apos; were 67 %, 100 % and 82 %, respectively. The LGE alone was the most sensitive test parameter with 86 %, providing a specificity of 100 % and accuracy of 92 %. Our study results can be applied to the subgroup of patients with &apos;&apos;infarct-like myocarditis&apos;&apos;, where we found that LGE alone was the

    Between 1955 and 1959, the housing estate at the Schiller park in Berlin-Wedding (Federal Republic in Germany) established in the 1920ies was expanded by four-storey house lines, the so-called Glas-Hoffmann buildings. Since 2008, this ensemble belongs to the Unesco World Heritage. In improving the thermal insulation of the building envelope and the adaptation of the building services to today&apos;s standards, therefore the architectural aesthetics of these buildings should not be endangered. The retrofitting was a pilot project of the research project &apos;&apos;Monument and energy - Postwar Modernism&apos;&apos;.

  13. Functional and morphological parameters with tissue characterization of cardiovascular magnetic imaging in clinically verified &apos;&apos;infarct-like myocarditis&apos;&apos;

    International Nuclear Information System (INIS)

    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 %. The diagnostic sensitivity, specificity, and accuracy of CMR in patients with &apos;&apos;infarct-like myocarditis&apos;&apos; were 67 %, 100 % and 82 %, respectively. The LGE alone was the most sensitive test parameter with 86 %, providing a specificity of 100 % and accuracy of 92 %. Our study results can be applied to the subgroup of patients with &apos;&apos;infarct-like myocarditis&apos;&apos;, where we found that LGE alone was the

    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.

  18. 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.

  19. 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.

Métodos: foram estudadas 18 mulheres com diagnóstico ultra-sonográfico de leiomioma uterino submetidas à EAU com partículas de álcool polivinílico (PVA. O acesso arterial foi realizado por punção da artéria femoral e a progressão do cateter foi monitorada até atingir seletivamente as artérias uterinas. A avaliação dos resultados foi realizada pelo estudo ultra-sonográfico antes e três meses após o procedimento. Foi realizado controle clínico evolutivo para avaliação das características menstruais e do volume uterino. Resultados: houve insucesso técnico em três casos por dificuldade de cateterização das artérias uterinas. O sangramento e a dismenorréia foram controlados no intervalo de três meses em 86 e 60% das pacientes, respectivamente. A média dos volumes uterinos iniciais foi de 381 cm³ e após 3 meses foi de 263 cm³. Houve redução média de 27,4% no volume uterino três meses após o tratamento. Três pacientes tiveram insuficiência ovariana clínica e laboratorial (20% dos casos. Conclusões: a EAU representa alternativa terapêutica para o tratamento dos leiomiomas uterinos. Em virtude do risco de insuficiência ovariana esse procedimento é reservado para pacientes com mais de 45 anos de idade ou com prole completa.

O pt-ABC provocou aumento de massa (13% em média entretanto o pt-B perda (-34% em média. A desidratação osmótica a 20°C por 60min em solução de NaCl a 10% reduziu a massa de fatias não pré-tratadas em 43%. Esse nível de redução de massa não pode ser atingido com o uso do pt-ABC, mas melhorou para 49% para fatias submetidas ao pt-B. Os pré-tratamentos reduziram o tempo de secagem (70°C e com circulação de ar de 18m³ h-1 de 150min para 60min para atingir o nível de atividade de água do produto seco igual ou menor a do produto comercial. As fatias submetidas ao pt-ABC ou do controle apresentaram boa capacidade de reidratação. As fatias que foram submetidas aos dois pré-tratamentos apresentaram coloração mais clara e menos enrugadas após secagem, aparência similar foi observada às do pt-ABC. O pt-ABC pode ser usado para se obter fatias de champignon seco com aspecto visual e capacidade de reidratação adequados para o desenvolvimento de novos produtos para consumo direto ou que necessite reidratação.

  10. Analysis of &apos;&apos;new physics&apos;&apos; in the flavor sector using effective field theory methods

    Energy Technology Data Exchange (ETDEWEB)

    Dassinger, Benjamin M.

    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.

    On-the-job training (OJT) has been with us in varying forms for longer than perhaps any other type of training. In reality, OJT is a process for accomplishing change; change in an employee&apos;s ability to perform assigned job duties. However, bringing about that change can often be a difficult process. A clear understanding of what change really is and what it entails is essential to easing its process. this document discusses the methodology in OJT and emphasizes the importance of communications in this process.

    2015-04-01

    Full Text Available O edema macular cistoide é uma das principais causas de baixa de visão após cirurgia de catarata. O processo inflamatório parece ser o principal fator causal do edema. São considerados fatores de risco complicações cirúrgicas, doenças retinianas prévias, diabetes, uveítes e uso de colírios de prostaglandinas. O diagnóstico é feito clinicamente, mas a angiografia fluoresceínica e a tomografia de coerência óptica também são ferramentas importantes para detectar o edema e auxiliar no diagnóstico diferencial. Apesar da profilaxia pré-operatória não ter evidência científica, ela é preconizada especialmente nos casos com fatores de risco. O tratamento inicial é realizado com associação de corticoide e anti-inflamatório não hormonais tópicos. Os casos crônicos e refratários têm diversas alternativas de tratamento, sendo o uso de triancinolona e antiangiogênicos intravítreos as mais utilizadas. Este artigo se propõe a discutir diversos aspectos do edema macular cistoide pseudofácico.

  17. 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.

    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.

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.

    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.

    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)

    The topic of &apos;&apos;green economy&apos;&apos; took centre stage at last year&apos;s UN conference on sustainable development in Rio de Janeiro. The term &apos;&apos;green economy&apos;&apos; has many interpretations to it, ranging from an emphasis on energy and resource efficiency in an otherwise ordinary economy to positions that are critical of growth as such. What can be considered as the essence of the concept of green economy, and what challenges need to be mastered on the way there? The present study shows that there is more to the term than most companies and consumers are aware of.

    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.

    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

Em relação a idade, as crianças da faixa de 11 a 13 anos revelaram-se em média mais temerosas que as de 7 a 9 anos. Quanto ao controle percebido as crianças mais novas percebem mais controle do que as mais velhas. Em geral os dados indicam que valores mais altos de medo relacionam-se com valores mais baixos de controle percebido. As crianças que tinham realizado tratamento odontológico com anestesia mostraram-se mais temerosas do que aquelas que não foram submetidas a anestesia, o que permite inferir que a etiologia de medo pode relacionar-se a esse procedimento que pode envolver a percepção de incontrolabilidade.

    Full Text Available Epilepsia é uma condição muito freqüente em todo o mundo. Na última década, várias opções terapêuticas surgiram ou foram aprimoradas. O principal método utilizado para decisão terapêutica baseia-se nos estudos randomizados, que representam o maior nível de evidência. Entretanto, mesmo estes estudos são passíveis de críticas e em alguns casos o tratamento de escolha permanece controverso. Nestas situações, a opinião dos especialistas, na área da epileptologia, com maior experiência clínica, passa a ter grande valor. O presente estudo tem como principal objetivo elaborar um consenso de tratamento das epilepsias, através da opinião de experts brasileiros no assunto. Este consenso poderá auxiliar na criação de manuais e estratégias para o tratamento de determinadas síndromes epilépticas, de acordo com os padrões socioeconômicos brasileiros.Epilepsy is a frequent condition in the world. Recently a study in Brazil showed prevalence of 18/1000 inhabitants in São José do Rio Preto, São Paulo State. In the last decade, new therapeutic options were discovered or developed. The main therapeutic decision method is based on randomized clinical trials. This method represents the higher level of evidence. However, even these studies have limitations and in some cases the treatment of choice remains controversial. In these instances, the epilepsy experts' opinions become helpful. In 2001 a similar study had been conducted in USA. The aim of this study is to create guidelines for epilepsy treatment based on the opinion of the Brazilian experts. These guidelines can be used to create manuals and strategies for the treatment of some epileptic syndromes according to Brazilian experts. As compared to the North-American guidelines our study better reflects the resources available in our country.

    Full Text Available A artrogripose é um termo utilizado para definir a presença, ao nascimento, de múltiplas contraturas articulares. A amioplasia é a principal e mais freqüente doença que cursa com contraturas congênitas e deformidade em eqüinovaro dos pés. A maioria dessas crianças tem bom potencial para a deambulação, havendo a necessidade da correção da deformidade dos pés para a posição plantígrada. O tratamento desses pés continua sendo um desafio devido à rigidez característica da doença e ao alto risco de recidiva. Os autores apresentam as opções de tratamento com base em uma revisão ampla da literatura, discutindo as técnicas cirúrgicas convencionais, como as liberações de partes moles e a talectomia, e a correção com o aparelho de Ilizarov. Ressaltam os estudos com resultados do tratamento primário do pé artrogripótico, na tentativa de fundamentar e auxiliar o ortopedista nesta difícil escolha.Arthrogryposis is the name used to define the presence of multiple joint contractures at birth. Amyoplasia is the main and most frequent among the diseases that take place with congenital contractures and equinovarus deformity of the foot. Most of these children have a good potential for walking, and a correction is required to correct their feet to the plantigrade position. Treatment of these feet presents a challenge due to the characteristic rigidity of the disease and to the high risk of recurrence. The authors present the treatment options based on a broad review of the literature, and discuss the conventional surgical techniques, such as the release of soft tissues and talectomy, and the correction of Ilizarov's device. They point to the studies that show the results of primary treatment of the arthrogrypotic foot in an attempt of providing a basis and giving a support to the orthopedist in this difficult choice.

    Full Text Available A epilepsia é uma das causas mais comuns de incapacidade funcional. Comorbidades psiquiátricas, como as psicoses, estão freqüentemente associadas à epilepsia. Psicoses na epilepsia (PNE requerem tratamento farmacológico mais cuidadoso, levando-se em conta a propensão dos antipsicóticos (AP em provocar crises convulsivas e o risco de interação farmacocinética com as drogas antiepilépticas (DAE. Após uma breve descrição da classificação e das principais características clínicas das PNE, foram discutidos alguns aspectos gerais do tratamento farmacológico das PNE e o uso de AP típicos e atípicos, destacando seu potencial para diminuir o limiar epileptogênico (LE, bem como possíveis interações AP/DAE. Os AP atípicos, à exceção da clozapina, demonstraram exercer menor influência sobre o LE. Quanto às interações farmacocinéticas, as principais DAE estiveram relacionadas com um aumento importante do metabolismo dos AP. Portanto, apesar do risco para convulsões por AP ser dose-dependente, doses mais elevadas de AP podem ser necessárias no tratamento das PNE.Epilepsy is one of the main causes of functional disability, and it is usually associated to psychiatric comorbidity, such as psychosis of epilepsy (POE. POE requires more careful pharmacological treatment, considering the propensity of the antipsychotics (AP to provoke seizures and the risk of pharmacokinetic interaction with anti-epileptic drugs (AEDs. We discussed the classification and the main types of POE, as well as some characteristics of AP typical and atypical, its potential to decrease the epileptogenic threshold (ET and possible interactions between AP and AED. Atypical AP, except clozapine, disclosed smaller influence on ET than typical AP. Regarding pharmacokinetic interactions, AEDs are related with a significant increase of the AP metabolism.

    1999-01-01

    Full Text Available Dentre as cefaléias primárias, pacientes com migrânea ou enxaqueca são os que mais procuram assistência médica. A sua prevalência é estimada em 12% da população sendo mais comum em mulheres com média de 18 a 20%, de 6% nos homens e de 4 a 8% nas crianças. O impacto econômico na produtividade e lazer é significativo, e as crises incapacitam o paciente para as atividades habituais. Com fisiopatologia complexa e ainda insuficientemente conhecida, a migrânea pode cursar com ataques de cefaléia intermitente, intensa e com características peculiares. A abordagem mais eficiente para o tratamento inclui o afastamento dos fatores deflagradores, tratamento medicamentoso preventivo, uso de medicamentos de resgate para os momentos de dor, e as terapias acessórias ou não medicamentosas. Para o tratamento profilático, objeto desta avaliação, utilizam-se várias classes de medicamentos que incluem os beta bloqueadores, antidepressivos tricíclicos (e mais recentemente inibidores seletivos da recaptação da serotonina, antagonistas dos canais de cálcio, antagonistas da serotonina, anticonvulsivantes e outros. Embora os seus mecanismos de ação nas migrâneas ainda sejam desconhecidos, parece que todos atuam nas funções serotoninérgica, noradrenérgica e gabaérgica centrais. Novas propostas de mecanismos de ação para algumas destas drogas incluem a inibição da formação do óxido nítrico e a ação específica de modulação em canais catiônicos neuronais. Quando individualizados e usados corretamente, estes medicamentos preventivos têm sido responsáveis por reduções importantes na frequência e intensidade dos episódios de migrânea, diminuindo assim o sofrimento e condutas duvidosas às quais os pacientes são usualmente submetidos.

Dcne. et Planch, (caixeta, é uma espécie nativa com vasta distribuição natural, rápido crescimento, grande porte e ainda pela sua rusticidade, é considerada uma espécie pioneira de potencial florestal para o Brasil. Porém, as suas sementes apresentam baixa germinabilidade. O objetivo deste trabalho foi avaliar o efeito de tratamentos pré-germinativos que pudessem maximizar o processo de germinação desta espécie. Foram testados os seguintes tratamentos: pré- -embebição em H20 por 8 h; escarificação química (HCl e H2SO4 a 70%; escarificação mecânica (por picotes no tegumento e com lixamento; lavagem com água destilada e lavagem em água + álcool (1:1 por 15, 30 e 45 min. As sementes foram colocadas para germinar em diferentes substratos. Realizou-se ainda teste de germinação in vitro. Sementes foram inoculadas em meio WPM, solidificado com ágar na presença de cinetina e ácido giberélico nas concentrações (0; 0,1; 0,5; 1,0 mg/l, e caseína hidrolisada na concentração 250 mg/l. A incubação foi a 25°C 1°C em câmara de germinação sob fotoperíodo de 16 horas luz, numa intensidade de 14,3 μE.m-².s-¹ ou no escuro. A germinação foi favorecida pelos pré-tratamentos de lavagens com água e água + álcool, sendo o tempo mais eficaz o de 45 min. A adição de cinetina e ácido giberélico provocou um aumento na germinabilidade de 40 a 70 %. Estes resultados confirmam a dormência tegumentar parcial e indicam a presença provável de substancias inibidoras nos tegumentos, removidas pelas lavagens.

  7. 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.

  12. 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.

    This paper investigated the treatment of neuroendocrine tumors (abdominal tumors) using of {sup 177}Lu DOTATATE radiopharmaceutical which is a type of treatment presently used in the experimental form in Brazil and, therefore, not contemplated in norms or specific use. This research studied the occupational doses of this treatment and suggested guidelines or rules of procedures viewing the radiological protection of workers involved and the public. The treatment were followed up by using two types of radiation detection, one a scintillator and a Geiger-Muller, and the measurements were performed in a public hospital at Rio de Janeiro and the other in a private hospital at Sao Paulo. It was observed that the equivalent occupational doses can variate from 160 {mu}Sv to 450 {mu}Sv, in function of operator, of stage of manipulation, and of the administration method, which can be through the use of infusion pump or manual injection. The use of infusion pump is highly recommended and the hospitalization of the patient until the dose rate measured at 1 m does not surpass 20 {mu}Sv/h

  1. 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.

    2006-10-15

    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.

  8. Radio-Tracking Studies of Adult Chinook Salmon and Steelhead to Determine the Effect of &apos;'Zero'&apos; River Flow During Water Storage at Little Goose Dam on the Lower Snake River, Final Report of Research.

    1985-09-01

    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.

    2011-02-01

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As doenças cerebrovasculares são responsáveis por grande parte das mortes no mundo. Entre os sobreviventes, a maioria das sequelas limitantes encontradas nos pacientes é motora, mas quando vias ou centros sensitivos são afetados os pacientes podem evoluir com alterações de sensibilidade na região corpórea representada pela área encefálica atingida. Quando a região acometida relaciona-se com o tálamo pode ocorrer síndrome talâmica. O objetivo deste relato de caso foi demonstrar o uso da eletroacupuntura como coadjuvante no tratamento de dor central, diagnosticada como síndrome talâmica de difícil controle com tratamento farmacológico. RELATO DO CASO: Paciente do sexo feminino, 46 anos, com história de acidente vascular encefálico isquêmico que acometeu região temporoparietal esquerda em abril de 2003, evoluiu com hemiparesia e hemitaxia à direita. Após um ano, iniciou-se quadro doloroso insidioso, contínuo, difuso em hemicorpo direito, acompanhado de alodínea e hiperalgesia, diagnosticado como síndrome talâmica. Em janeiro de 2006, deu entrada no serviço de terapia da dor e medicina paliativa da Santa Casa de Misericórdia de São Paulo e iniciou tratamento farmacológico com resposta ruim, sendo programada para abordagem neurofuncional. Em julho de 2009, propôs-se à paciente tratamento com eletroacupuntura na tentativa de melhor controle de quadro álgico. Foram realizadas sessões de eletroacupuntura em pontos em couro cabeludo e membros. Após a décima primeira sessão, a paciente encontrava-se com quadro álgico controlado, sem uso de opioides e amitriptilina tópica, sensação de bem-estar elevada, maior coordenação motora, diminuição global da dor, sendo completa em mão e face. CONCLUSÕES: A eficácia da eletroacupuntura no controle do quadro álgico e no aumento do bem-estar encontra-se em concordância com estudos modernos, os quais demonstraram ativação de vias

    Full Text Available JUSTIFICATIVA: O tratamento dos pacientes com síndrome demencial depende do diagnóstico correto de sua etiologia e da utilização de critérios objetivos de avaliação do curso da doença. O diagnóstico preciso da demência vascular (Dva é difícil e nossos conhecimentos sobre a organização neuropsicológica do cérebro em estados de doença e a evolução da doença são precários, tornando penosa a avaliação das respostas a diferentes intervenções. MÉTODOS: São discutidos os critérios diagnósticos, os instrumentos de avaliação do curso da Dva e as diferentes intervenções terapêuticas atualmente em estudo. RESULTADOS: O uso de critérios diagnósticos estritos e a otimização dos métodos de avaliação evolutiva são passos importantes para otimizar o tratamento dos pacientes com DVa. A prevenção de novos eventos cerebrovasculares é a única medida comprovadamente eficaz para promover estabilização e talvez regressão das alterações cognitivas e comportamentais nestes pacientes. As evidências de possível benefício de estimulantes inespecíficos do metabolismo cerebral e de drogas neuroprotetoras não são suficientes para indicar seu uso rotineiro. Medidas de estruturação do ambiente, o uso racional e parcimonioso de medicamentos em geral, e a definição através de testes neuropsicológicos de rotas terapêuticas adaptadas às necessidades de cada paciente são também importantes. CONCLUSÕES: Critérios diagnósticos e de acompanhamento evolutivo da DVa são ainda inadequados. A prevenção de novos episódios cerebrovasculares é a base do tratamento dos pacientes com DVa. O uso criterioso de drogas psiquiátricas, uma abordagem neurocognitiva dirigida aos déficits de cada paciente e a estruturação do ambiente para reduzir demandas desnecessárias e cansaço são importantes medidas complementares, mas deixam grande margem para otimização do tratamento.

    Full Text Available As fraturas representam uma fadiga de estrutura óssea. O estudo dos conceitos básicos sobre a organização do tecido ósseo, o mecanismo indutor das fraturas e o processo de consolidação são temas importantes da moderna traumatologia. Alterações estruturais nos ossos ocorrem em decorrência de complexo sistema de forças deformadoras. As lesões podem ocasionar alterações em diferentes tecidos ósseos. O tratamento das fraturas é usualmente realizado pela fixação interna e externa, mas experimentos modernos apontam para que o processo biológico de reparação das fraturas seja melhor do que a fixação metálica.

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.

    Full Text Available Papilomatose respiratória recorrente ou papilomatose laríngea recorrente é uma doença da laringe, causada pelo papiloma vírus humano, caracterizada por lesões epiteliais verrucosas e, geralmente, recorrentes. Na literatura são descritos diversos tipos de tratamento, como cirurgia a frio, a laser e/ou uso de microdebridador, além das terapias adjuvantes; todas no sentindo de diminuir possíveis sequelas permanentes da doença. OBJETIVO: Realizar uma revisão de literatura a respeito desta doença com ênfase nas técnicas cirúrgicas e terapias adjuvantes mais utilizadas atualmente. MÉTODO: Utilizou-se a metodologia de revisão bibliográfica, por meio de levantamentos em base de dados eletrônicos de domínio público, entre 1992-2012, utilizando-se as palavras-chave: papiloma, infecções por papillomavírus, laringe, terapêutica, vacinas contra papillomavírus. RESULTADOS: Foram levantados 357 artigos, dos quais 49 foram usados como base para esta revisão. Os trabalhos científicos apontam para a redução de recidiva na maioria das terapêuticas adjuvantes. Entretanto, o levantamento demonstrou metodologias e amostras diferentes, o que não permitiu comparar os tipos de tratamento e de terapias adjuvantes. CONCLUSÃO: A escolha da técnica cirúrgica varia entre os autores, porém, há uma tendência atual ao uso do microdebridador. As terapias adjuvantes recentes, como cidofovir, vacina tetravalente contra o papiloma vírus humano e bevacizumab, necessitam de estudos mais amplos.

    Full Text Available Trata-se de um estudo bibliográfico de caráter descritivo, realizado através de revisão de literatura. Foram utilizados como fontes, artigos e resumos das bases de dados de bibliotecas virtuais, com os objetivos de apresentar os benefícios do toque como ferramenta eficaz para promoção do bem-estar em idosos e, valorizar o toque no tratamento geriátrico e gerontológico. Os estudos analisados revelaram que o toque têm se mostrado uma ferramenta eficaz no tratamento de idosos, principalmente, naqueles que apresentam síndromes demenciais, como alzheimer, e ainda, nas patologias como o câncer, e outras. Segundo as pesquisas, alguns idosos relataram sensação de relaxamento, redução da ansiedade produzindo bem-estar e conforto. No entanto, é necessário que os profissionais de saúde tenham interesse em conhecer os aspectos multifatoriais que envolvem os idosos, para que o toque seja uma “atitude solidária”, realizado com afetividade, comprometimento, ética e profissionalismo, que garanta a promoção do bem-estar e um atendimento de qualidade aos idosos. Sugere-se assim, a inserção do toque de forma mais ampla no contexto de pesquisa e na prática baseada em evidências, criando a possibilidade de desenvolver uma metodologia à sua aplicação na promoção da saúde e melhora da qualidade de vida dos idosos.

    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.

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

    2009-06-15

    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

    Full Text Available As fraturas do côndilo mandibular, dentre as fraturas faciais, são as que apresentam o maior número de controvérsias quanto ao seu tratamento e maior dificuldade de diagnóstico. A escolha de um tratamento - cirúrgico, bloqueio maxilo-mandibular, fisioterapia elástica ou associação -, está diretamente ligado ao tipo de fratura, à idade do paciente e ao grau de alteração funcional em decorrência da fratura. Os exames por imagens são importantes para o diagnóstico e classificação da fratura, no entanto, os achados clínicos são mais relevantes na indicação de um tratamento cirúrgico ou conservador. Este trabalho tem como objetivo apresentar uma classificação das fraturas do côndilo relacionada com o seu tratamento e relatar dois casos clínicos, sendo um tratado de forma cirúrgica e o outro conservadoramente, discutindo as vantagens e desvantagens do tratamento cirúrgico, bem como as indicações e contra-indicações.Condylar fractures are considered one of the most controversial fractures in face regarding treatment and diagnostic difficulty. Choosing the best treatment, such as surgery, inter maxillary fixation, physiotherapy or their association is directly related to fractures type, patient age and functional impairment degree. Clinical findings are relevant for proper diagnostic but image is fundamental for a precise treatment indication. We present a novel classification based on the condyle deviation and also propose a treatment for each type of fracture regarding age and clinical symptoms. We illustrate this paper with a description of two cases, one submitted to surgical and other to clinical treatment.

    Full Text Available OBJETIVO: O objetivo deste artigo é apresentar uma revisão sistemática da literatura sobre tratamentos psicológicos oferecidos para usuários de crack. MÉTODOS: Foi realizada uma revisão sistemática por meio de uma busca na literatura internacional e nacional, indexada nas bases de dados Medline, SciELO, Lilacs e Web of Science. Os descritores utilizados foram: crack or crack cocaine or cocaine smokers (crack and psychosocial treatment or psycotherapy or psychosocial treatment (tratamento psicológico e a busca incluiu artigos publicados no período de 2001 a 2011. RESULTADOS: No total foram encontrados 155 artigos por meio dos descritores utilizados. Os artigos foram agrupados em três dimensões: tratamentos psicossociais na internação e cuidados continuados, relaxamento respiratório e outras técnicas comportamentais e abordagens fundamentadas na Entrevista Motivacional, Cognitivo-Comportamental e Modelo Transteórico de Mudança. CONCLUSÃO: Com base nos estudos examinados, pode ser formulado um elenco de algumas intervenções que estão sendo estudadas para o tratamento de usuários de crack e algumas apresentam resultados satisfatórios. Os poucos esforços de comparação entre técnicas resultaram em evidências de pouca ou nenhuma diferença, ainda que se registre o benefício para os usuários na aplicação de qualquer delas. Não existe consenso acerca da efetividade no tratamento de usuários de crack. Parece oportuno e necessário o aprofundamento dos estudos nesse campo.

    Full Text Available CONTEXTO: O transtorno de ansiedade social (TAS, apesar da baixa taxa de detecção e do alto índice de comorbidades associadas, é considerado uma condição tratável. Apesar da resposta estabelecida a diversas classes de medicamentos, os algoritmos para o tratamento do TAS necessitam de atualização constante. OBJETIVO: Realizar revisão sistemática da literatura no que diz respeito à eficácia dos tratamentos farmacológicos relativos ao TAS, a partir de estudos controlados, conduzidos no período de 2005 a 2010. MÉTODO: Foram utilizados os indexadores eletrônicos PsycoInfo, Lilacs e Medline, utilizando-se as palavras-chave: "social phobia or social anxiety and treatment". RESULTADOS: De acordo com critérios de inclusão adotados, 29 artigos foram incluídos e analisados. Mostram-se eficazes para o tratamento do TAS as seguintes drogas, de acordo com a classe: a ISRSs: escitalopram, fluvoxamina, citalopram, GR205171 e sertralina; b ISRSN: venlafaxina; c IMAOs: fenelzina, moclobemina; d aminoácidos: d-cicloserina; f anticonvulsivantes: tiagabina. CONCLUSÃO: Os ISRSs e os ISRSNs têm seu uso estabelecido e ainda continuam sendo considerados primeira opção de tratamento. Porém, destaca-se o potencial futuro da d-cicloserina e dos anticonvulsivantes, com necessidade de um número maior de estudos controlados que confirmem os achado iniciais. A ação das diferentes drogas em nível neurobiológico, bem como dos tratamentos associados, necessita ainda ser mais explorada.

    Full Text Available Um dos maiores problemas na pós-colheita da lichia é o escurecimento do pericarpo, cuja cor vermelha se torna totalmente escurecida em 48 horas, sob 25 ºC. Tecnologias que possam controlar o escurecimento do pericarpo são valiosas, e é o foco principal da pesquisa na área de pós-colheita. O objetivo deste trabalho foi avaliar a vida útil de lichias 'Bengal', armazenadas a 20 ºC e 82 %UR após o tratamento hidrotérmico e/ou imersão em solução de HCl. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 4 x 7, com 3 repetições, onde o primeiro fator correspondeu aos tratamentos: testemunha; imersão em HCl a 1%, por 6 minutos; tratamento hidrotérmico, com imersão em água a 52 ºC por 1 minuto, seguido de resfriamento em água a 10 ºC, por 6 minutos; e tratamento hidrotérmico, seguido de resfriamento em HCl a 1%, a 10 ºC, por 6 minutos. O segundo fator foram os períodos de armazenamento: 0; 1; 2; 3;6; 9 e 12 dias. A combinação entre tratamento hidrotérmico (52 ºC por 1 minuto e resfriamento em HCl a 1% permite conservar a coloração das lichias 'Bengal' por até dois dias. Mesmo assim há escurecimento em 25% da superfície.

    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.
