    In this work various treatments for protecting reinforcing steels against corrosion induced by chlorides have been evaluated. Additives to mortars and surface treatments given to reinforcing steels were evaluated as corrosion protection measures. In the preliminary tests the corrosion resistance of a CA 50 steel treated by immersion in nearly 50 different solutions, was determined. The solutions were prepared with tannins (from various sources) and/or benzotriazole, and during immersion, a surface film formed on the steel. The corrosion resistance of the coated steels was evaluated in a saturated Ca(OH){sub 2} solution with 5% (wt) NaCl. Preliminary tests were also carried out with mortars reinforced with uncoated steel to which tannin or lignin was added. Two organic coatings, a monocomponent and a bicomponent type, formulated specially for this investigation, with both tannin and benzotriazole, were also tested in the preliminary tests to select the coating with better corrosion protection property. The bicomponent type (epoxy coating) showed better performance than the monocomponent type coating, and the former was therefore chosen to investigate the corrosion performance on CA 50 steel inside mortar specimens. From the preliminary tests, two solutions with tannin from two sources, Black Wattle (Acacia mearnsii) and Brazilian tea (Ilex paraguariensis St. Hill), to which benzotriazole and phosphoric acid were added, were chosen. Mortar specimens reinforced with CA50 steel treated by immersion in these two solutions were prepared. Also, epoxy coated CA50 steel was tested as reinforcement inside mortar specimens. Mortars reinforced with uncoated CA50 steel were also prepared and corrosion tested for comparison. The effect of tannin and lignin as separate additives to the mortar on the corrosion resistance of uncoated steel was also studied. The reinforced mortar specimens were tested with various cycles of immersion for 2 days in 3.5% (wt) NaCl followed by with air drying for 5 days. The corrosion tests used in this investigation were gravimetric and electrochemical tests. The results showed satisfactory corrosion performance for all kinds of protection measures. However, the performance depended on the type of protection used. The best performance was obtained with tannin containing epoxy coated steel, followed by the steel treated by immersion in tannin containing solutions and finally by the addition of tannin (Black Wattle) or lignin to the mortar. All the protection measures evaluated in this study are economically viable and environmentally friendly and can therefore be considered for protecting reinforcement steels against corrosion.

    Sharing of data about variation and the associated phenotypes is a critical need, yet variant information can be arbitrarily complex, making a single standard vocabulary elusive and re-formatting difficult. Complex standards have proven too time-consuming to implement. The GEN2PHEN project addressed these difficulties by developing a comprehensive data model for capturing biomedical observations, Observ-OM, and building the VarioML format around it. VarioML pairs a simplified open specification for describing variants, with a toolkit for adapting the specification into one's own research workflow. Straightforward variant data can be captured, federated, and exchanged with no overhead; more complex data can be described, without loss of compatibility. The open specification enables push-button submission to gene variant databases (LSDBs) e.g., the Leiden Open Variation Database, using the Cafe Variome data publishing service, while VarioML bidirectionally transforms data between XML and web-application code formats, opening up new possibilities for open source web applications building on shared data. A Java implementation toolkit makes VarioML easily integrated into biomedical applications. VarioML is designed primarily for LSDB data submission and transfer scenarios, but can also be used as a standard variation data format for JSON and XML document databases and user interface components. VarioML is a set of tools and practices improving the availability, quality, and comprehensibility of human variation information. It enables researchers, diagnostic laboratories, and clinics to share that information with ease, clarity, and without ambiguity.

    The use of natural fibers in composite materials has been highlighted in the scientific field. However, its application in polymer matrices usually requires surface modifications. The objective of this work was to treat carnauba's straw fibers with NaOH 1 % and NaOH 5% solutions and measure the water absorption. We used the X-ray diffraction (XRD configuration “Bragg- Brentano) for verification of the crystalline phases and Fourier Transform Infrared Spectroscopy (FTIR) to identify functional groups. The alkali treatment allowed the solubilization of the hemicellulose and lignin without causing changes to cellulose, as indicated by FTIR spectrophotometry and by the increase in crystallinity content. The samples showed the typical peaks of constituents of the fiber. The natural fiber showed an average water absorption of 256 %; fiber treated with NaOH 1%, 315 %; and treated with NaOH 5%, 405 %. Therefore, it is evident improvement in hydrophilicity, fundamental aspect in the interaction fiber / matrix. (author)

    Hair follicle stem cells (HfSCs) play crucial roles in hair follicle morphogenesis and hair cycling. These stem cells are self-renewable and have the multi-lineage potential to generate epidermis, sebaceous glands, and hair follicle. The separation and identification of hair follicle stem cells are important for further research in stem cell biology. In this study, we report on the successful enrichment of rat hair follicle stem cells through vario magnetic activated cell sorting (Vario MACS) and the biological characteristics of the stem cells. We chose the HfSCs positive surface markers CD34, α6-integrin and the negative marker CD71 to design four isolation strategies: positive selection with single marker of CD34, positive selection with single marker of α6-integrin, CD71 depletion followed by CD34 positive selection, and CD71 depletion followed by α6-integrin positive selection. The results of flow cytometry analysis showed that all four strategies had ideal effects. Specifically, we conducted a series of researches on HfSCs characterized by their high level of CD34, termed CD34 bri cells, and low to undetectable expression of CD34, termed CD34 dim cells. CD34 bri cells had greater proliferative potential and higher colony-forming ability than CD34 dim cells. Furthermore, CD34 bri cells had some typical characteristics as progenitor cells, such as large nucleus, obvious nucleolus, large nuclear:cytoplasmic ratio and few cytoplasmic organelles. Our findings clearly demonstrated that HfSCs with high purity and viability could be successfully enriched with Vario MACS

    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 objetivo desta revisão foi coletar dados sobre tratamento da dor em queimados. CONTEÚDO: Foi feita revisão sobre os mecanismos de dor, avaliação do paciente com queimadura e o tratamento farmacológico e não farmacológico. CONCLUSÕES: O manejo da dor em pacientes vítimas de queimaduras ainda é um desafio por parte da equipe multiprofissional. A avaliação frequente e contínua da resposta apresentada pelo paciente é muito importante, tendo em vista os vários momentos por que passa o paciente internado em decorrência de uma queimadura, além de uma terapêutica combinada com medicações analgésicas e medidas não farmacológicas. Entender a complexidade de alterações fisiopatológicas, psicológicas e bioquímicas apresentadas por um paciente em tratamento de queimadura é o primeiro passo para alcançar o sucesso no seu manejo analgésico.

    A new Job's tear cultivar ''Hatohikari'', developed at the Tohoku National Agricultural Experiment Station, Morioka, Japan was registered as Norin No.2 Job's tear and released by Japan's Ministry of Agriculture, Forestry and Fisheries in 1995. ''Hatohikari'' is a progeny from a gamma-ray radiated mutant of ''Okayama-zairai'' in 1980. ''Okayama-zairai'' shows high yield and good quality. However, its demerits are late maturity and long plant height. The major agronomic characteristics of the new cultivar ''Hatohikari'' are as follows: The maturity is earlier than that of ''Okayama0zairai'', yielding ability is 38% higher than that of ''Okayama-zairai , the plant height is 30 cm shorter than that of ''Okayama-zairai'' and it is suitable for combine harvest. ''Hatohikari'' has large seeds with good quality for tea processing. Shattering is easy, and resistance to leaf blight is medium. ''Hatohikari'' is adaptable to middle mountain regions in chugoku district of Japan. This cultivar has been recommended in Hiroshima prefecture since 1995

Resultados satisfatórios foram observados em 82% dos 65 pacientes com epilepsia focal; os 3 pacientes com crises P.M. não foram influenciados pelo tratamento. A ação sobre as manifestações psíquicas que acompanhavam o quadro crítico ou intercrítico das crises ficou bem evidenciada. Os pacientes melhoraram de seus sintomas na grande maioria dos casos, conseguindo adaptar-se melhor no ambiente familiar, profissional e escolar. O efeito sobre as alterações eletrencefalográficas é moderado, e a evolução clínica não acompanha as modificações dos traçados. As doses usadas, em geral de 400 a 600 mg diários, são suficientes para o controle das crises na maioria dos casos e estão muito abaixo dos limites considerados como de segurança. As reações secundárias foram observadas em pequeno número de casos e foram sempre transitórias. O Tegretol representa, em nossa opinião, recurso de valor no trataemnto das epilepsias focais, particularmente nas crises psicomotoras.

    Frameless stereotactic brain biopsy systems are widely used today. VarioGuide (VG) is a relatively novel frameless system. Its accuracy was studied in a laboratory setting but has not yet been studied in the clinical setting. The purpose of this study was to determine its accuracy and diagnostic yield and to compare this with frame-based (FB) stereotaxy. Overall, 53 patients (33 males and 20 females, 60 ± 15 years old) were enrolled into this prospective, randomized, single-center study. Twenty-six patients were randomized into the FB group and 27 patients into the VG group. Real trajectory was pointed on intraoperative magnetic resonance. The distance of the targets and angle deviation between the planned and real trajectories were computed. The overall discomfort of the patient was subjectively assessed by the visual analog scale score. The median lesion volume was 5 mL (interquartile range [IQR]: 2-16 mL) (FB) and 16 mL (IQR: 2-27 mL) (VG), P = 0.133. The mean distance of the targets was 2.7 ± 1.1 mm (FB) and 2.9 ± 1.3 mm (VG), P = 0.456. Mean angle deviation was 2.6 ± 1.3 deg (FB) and 3.5 ± 2.1 deg (VG), P = 0.074. Diagnostic yield was 93% (25/27) in VG and 96% (25/26) in FB, P = 1.000. Mean operating time was 47 ± 26 minutes (FB) and 59 ± 31 minutes (VG), P = 0.140. One minor bleeding was encountered in the VG group. Overall patient discomfort was significantly higher in the FB group (visual analog scale score 2.5 ± 2.1 vs. 1.2 ± 0.6, P = 0,004). The VG system proved to be comparable in terms of the trajectory accuracy, rate of complications and diagnostic yield compared with the "gold standard" represented by the traditional FB stereotaxy for patients undergoing brain biopsy. VG is also better accepted by patients. Copyright © 2017 Elsevier Inc. All rights reserved.

    To evaluate and compare the uniformity of angle Kappa adjustment between Oculyzer and Topolyzer Vario topography guided ablation of laser in situ keratomileusis (LASIK) by EX500 excimer laser for myopia. Totally 145 cases (290 consecutive eyes )with myopia received LASIK with a target of emmetropia. The ablation for 86 cases (172 eyes) was guided manually based on Oculyzer topography (study group), while the ablation for 59 cases (118 eyes) was guided automatically by Topolyzer Vario topography (control group). Measurement of adjustment values included data respectively in horizontal and vertical direction of cornea. Horizontally, synclastic adjustment between manually actual values (dx manu ) and Oculyzer topography guided data (dx ocu ) accounts 35.5% in study group, with mean dx manu /dx ocu of 0.78±0.48; while in control group, synclastic adjustment between automatically actual values (dx auto ) and Oculyzer topography data (dx ocu ) accounts 54.2%, with mean dx auto /dx ocu of 0.79±0.66. Vertically, synclastic adjustment between dy manu and dy ocu accounts 55.2% in study group, with mean dy manu /dy ocu of 0.61±0.42; while in control group, synclastic adjustment between dy auto and dy ocu accounts 66.1%, with mean dy auto /dy ocu of 0.66±0.65. There was no statistically significant difference in ratio of actual values/Oculyzer topography guided data in horizontal and vertical direction between two groups ( P =0.951, 0.621). There is high consistency in angle Kappa adjustment guided manually by Oculyzer and guided automatically by Topolyzer Vario topography during corneal refractive surgery by WaveLight EX500 excimer laser.

    In this paper, we revisit the idea of locked inflation, which does not require a potential satisfying the normal slow-roll condition, but suffers from the problems associated with ''saddle inflation''. We propose a scenario based on locked inflation, however, with an alternative evolution mechanism of the ''waterfall field'' {phi}. Instead of rolling down along the potential, the {phi} field will tunnel to end the inflation stage like in old inflation, by which the saddle inflation could be avoided. Further, we study a cascade of old locked inflation, which can be motivated by the string landscape. Our model is based on the consideration of making locked inflation feasible so as to give a working model without slow roll; It also can be seen as an effort to embed the old inflation in string landscape.

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

    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)

    Full text: Magnetic nanoparticles have been used in several biomedical applications, spanning from cell separation, early diagnosis of metastasis to even the treatment of cancer via magnetic hyperthermia (MH). This last technique consists in the increase of temperature of nanoparticles when their magnetic moments interact with a magnetic alternating field. This effect has been suggested as an innovative therapy to cancer treatment, due to the delivery of heat or therapeutic agents, such as drugs, genes, and others. In addition, several clinical studies has demonstrated synergetic effects between hyperthermia and radiotherapy [1]. This indicates a great therapeutic potential for this noninvasive and targeted technique. In this talk we will discuss results from the literature and from our own group in the treatment of cancer via magnetic hyperthermia. Several types of magnetic nanoparticles suggested for this application will be discussed, as well as the historical evolution of this procedure, which although suggested in the late 50' only recently was approved in Europe for treatment of humans with brain tumors.

    Ichihime, a new soybean variety registered as ''Soybean Norin 103'', was developed at Kyushu National Agricultural Experiment Station in 1995. It was selected from the progeny induced by a cross between Kankei 2 and Kankei 1 using gamma-ray irradiation. ''Ichihime'' is a medium-early maturing variety with determinate growth. It has broad leaflets, and purple flowers. The color of its pubescence is light tawny and its pods are dark brown. The main stem length, number of main stem nodes, and seed size are medium. It has strong resistance to the soybean mosaic virus (SMV), medium resistance to the soybean cyst nematode, and medium resistance to purple seed stain. The yield of Ichihime is slightly lower than Suzuyutaka, but classified as medium. The protein components of its seeds are medium and the firmness of the tofu (soybean curd) is the same as that of Suzuyutaka. Ichihime lacks all seed lipoxygenase isozymes and is recommended for new type of soybean food processing materials. Ichihime is suitable for growth in the southern part of the Tohoku area and the northern part of the Kanto area

    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

    An 88-yr-old man, with prior left upper lobectomy and phrenic nerve injury, had a ventilation/perfusion lung image. Both wash-in and equilibrium ventilation images showed no radioactive gas in the left lung. Nevertheless, the left lung was perfused. A similar result was obtained on a repeat study 8 days later. Delayed images, during washout, showed some radioactive gas in the left lung. Nearly absent ventilation (but continued perfusion) of that lung might have been related to altered gas dynamics brought about by the prior lobectomy, a submucosal bronchial lesion, phrenic nerve damage, and limited motion of the left part of the diaphragm. This case raises the issue of the degree of ventilation (and the phase relationship between the lungs) required for the entry of radioactive gas into a diseased lung, and the production of a ''reversed ventilation/perfusion mismatch.''

    Full Text Available A hemofilia é um grave distúrbio hereditário da coagulação sanguínea, causada pela deficiência da atividade coagulante do fator VIII (hemofilia A ou IX (hemofilia B. A doença é decorrente de alterações nos genes codificantes destes fatores localizados no braço longo do cromossomo sexual X. 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

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.

    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)

    Two personal cases of &apos;&apos;de novo&apos;&apos; aneurysms of the anterior communicating artery (ACoA) occurring 9 and 4 years, respectively, after endovascular carotid occlusion are described. A review of the 30 reported cases (including our own two) of &apos;&apos;de novo&apos;&apos; aneurysms after occlusion of the major cerebral vessels has shown some features, including a rather long time interval after the endovascular procedure of up to 20-25 years (average 9.6 years), a preferential ACoA (36.3%) and internal carotid artery-posterior communicating artery (ICA-PCoA) (33.3%) location of the &apos;&apos;de novo&apos;&apos; aneurysms, and a 10% rate of multiple aneurysms. These data are compared with those of the group of reported spontaneous &apos;&apos;de novo&apos;&apos; aneurysms after SAH or previous aneurysm clipping. We agree that the frequency of &apos;&apos;de novo&apos;&apos; aneurysms after major-vessel occlusion (two among ten procedures in our series, or 20%) is higher than commonly reported (0 to 11%). For this reason, we suggest that patients who have been submitted to endovascular major-vessel occlusion be followed up for up to 20-25 years after the procedure, using non-invasive imaging studies such as MR angiography and high-resolution CT angiography. On the other hand, periodic digital angiography has a questionable risk-benefit ratio; it may be used when a &apos;&apos;de novo&apos;&apos; aneurysm is detected or suspected on non-invasive studies. The progressive enlargement of the ACoA after carotid occlusion, as described in our case 1, must be considered a radiological finding of risk for &apos;&apos;de novo&apos;&apos; aneurysm formation.

Los datos fueron clasificados y analizados de acuerdo con la región geográfica de origen de los individuos. Se estimaron las frecuencias génicas y su bondad de ajuste al equilibrio de Hardy-Weinberg mediante el método de máxima verosimilitud. Se observó la existencia de una estructuración geográfica en la población de Costa Rica. Todas las regiones de Costa Rica presentan valores de heterocigosidad mucho mayores a los observados en los pueblos indígenas costarricenses, pero semejantes o ligeramente mayores a los encontrados en poblaciones de España. El análisis de distancias génicas evidenció que las regiones de Costa Rica se agrupan próximas entre sí, en posiciones intermedias entre las amerindias y las de España, hecho que es coherente con el planteamiento que atribuye un origen mestizo a la población general de Costa Rica. Además, los datos contradicen la idea de que la región Central tiene una población radicalmente diferente a las demás regiones del país. Estos marcadores revelan pobres valores de probabilidad de exclusión forense y de paternidad, lo que confirma la importancia de su reemplazo por marcadores de ADN en los esquemas de identificación humana de los sistemas de investigación judicial.

    The observational fact that the present values of the densities of dark energy and dark matter are of the same order of magnitude, ρ{sub de0}/ρ{sub dm0} ∝ O(1), seems to indicate that we are currently living in a very special period of the cosmic history. Within the standard model, a density ratio of the order of one just at the present epoch can be seen as coincidental since it requires very special initial conditions in the early Universe. The corresponding &apos;&apos;why now&apos;&apos; question constitutes the cosmological &apos;&apos;coincidence problem&apos;&apos;. According to the standard model the equality ρ{sub de} = ρ{sub dm} took place &apos;'recently'&apos; at a redshift z ∼ 0.55. The meaning of &apos;'recently'&apos; is, however, parameter dependent. In terms of the cosmic time the situation looks different. We discuss several aspects of the &apos;&apos;coincidence problem&apos;&apos;, also in its relation to the cosmological constant problem, to issues of structure formation and to cosmic age considerations.

    Full Text Available A suinocultura caracteriza-se como uma atividade de alto impacto ambiental, devido a grande quantidade de dejetos com alta carga de poluentes, lançados no meio ambiente. No entanto, existem diversas tecnologias, e sistemas de tratamento, com a capacidade de reduzir o poder poluente dos dejetos da suinocultura. O presente trabalho tem como objetivo analisar as principais tecnologias e sistemas de tratamentos para os dejetos da suinocultura, presentes em publicações brasileiras. Os resultados obtidos nestas publicações apresentaram-se de certa forma satisfatórios em relação à redução da carga de poluentes dos efluentes da suinocultura. Entretanto, pouco se sabe sobre o comportamento da redução dos poluentes em função de parâmetros dimensionais e temporais das tecnologias ou dos sistemas de tratamento. Tal desconhecimento dificulta o dimensionamento de sistemas de tratamento, desconsiderando a relação existente entre investimento e redução do poder poluente dos dejetos. Dentro deste contexto, a modelagem e otimização de sistemas pode ser uma ferramenta muito útil para o dimensionamento de tecnologias e sistemas de tratamento de dejetos de suínos.

    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. PMID:11560764

    2015-01-01

    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.

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

    Full Text Available Apesar da grande heterogeneidade das manifestações clínicas relacionadas à endometriose, observa-se a sua elevada prevalência em mulheres inférteis e portadoras de dor pélvica crônica. O impacto sócio-econômico desta afecção enigmática é elevado e os dados relacionados à eficácia das diferentes abordagens terapêuticas descritas são bastante conflitantes. Assim, os objetivos do presente artigo são apresentar as evidências científicas disponíveis acerca das diferentes modalidades terapêuticas aplicáveis e estabelecer recomendações para o tratamento da infertilidade e da dor pélvica crônica relacionadas à endometriose. Em pacientes com endometriose mínima ou leve a supressão da função ovariana não é efetiva para melhorar a fertilidade, mas a ablação das lesões associadas à adesiólise parece ser mais efetiva do que a realização exclusiva da laparoscopia diagnóstica. Não há evidências suficientes para determinar se a excisão cirúrgica em casos de doença moderada ou severa melhoraria as taxas de gestação. A fertilização in vitro parece ser uma abordagem adequada, especialmente nos casos de coexistência de fatores de infertilidade e/ou falha de outras abordagens terapêuticas. Deve-se avaliar a possibilidade de usar agonistas do GnRH por 3 a 6 meses, previamente à realização de fertilização in vitro. Em relação ao alívio da dor, verifica-se que a supressão da função ovariana por 3 a 6 meses em pacientes com doença confirmada laparoscopicamente reduz a dor associada à endometriose. Todas as medicações estudadas parecem apresentar eficácia similar, embora os efeitos adversos e de os custos sejam diferentes. A ablação das lesões endometrióticas reduz a dor associada à endometriose, sendo menos efetiva nos casos de doença mínima. A exérese de endometriomas com diâmetro > 4 cm parece melhorar a taxa de fecundidade natural e após procedimentos de reprodução assistida, além de

    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.

    The Dirac electron theory for the evanescent wave surrounding an infinitely long cylindrical magnet with zero surface polarization and the requirement of the single valuedness of this wave are used to show that the magnetic flux is quantized in units h/2e emu. The same quantization is shown for a general &apos;'autistic'&apos; magnet (i.e. magnet completely trapping its flux), thus establishing complete external equivalence of the &apos;'autistic'&apos; magnet with the &apos;&apos;perfect solenoid&apos;&apos;.

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

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

    Full Text Available RESUMO: A mastite é considerada o maior problema dos animais destinados à produção de leite. Altera a sua composição e aumenta a contagem de células somáticas (CCS. Os micro-organismos envolvidos na doença podem ser origem infecciosa, como Staphylococcus aureus, ou ambiental, tal como Escherichia coli. A cultura bacteriana é uma ferramenta de diagnóstico e auxilia na detecção do patógeno causador da mastite. No entanto, fatores como fagocitose podem desencadear um resultado negativo. Quando estabelecido um programa de controle de mastite, o diagnóstico precoce e o início do tratamento adequado dos casos clínicos são fundamentais para se atingir os objetivos e seu sucesso, está relacionado com o patógeno envolvido. A indicação do tratamento de longa duração, ou terapia estendida, tem melhorado a resposta ao tratamento em casos de mastite por S. aureus, no entanto, com 30-50% de cura. Do ponto de vista do manejo dos animais, devido a alta contagiosidade deste patógeno, sua persistência no rebanho e custo em função ao tratamento, muitas vezes, o descarte do animal tem sido priorizado a fim de controlar os casos de mastite em propriedades. As medidas de controle são muito importantes para contribuir com a redução de casos de mastite por este patógeno. A indicação do tratamento intramamário associada com sistêmico tem poder efetivo em casos de mastite por E. coli, cujos casos agudos apresentam-se com sepse e toxemia. São abordados ainda aspectos de tratamentos alternativos das mastites, utilizados principalmente no processo orgânico de produção leiteira.

    2014-05-01

    Full Text Available Esse trabalho tem por objetivo analisar a importância do biodigestor UASB no tratamento de dejetos suínos. A suinocultura possui papel importante quanto ao desenvolvimento econômico do Brasil. No entanto, o aumento de produção vem causando problemas ambientais graves, por conta do grande volume de resíduos sólidos gerados pela atividade. O desenvolvimento de métodos de tratamento de dejetos que agreguem valor à produção e respeitem as leis ambientais é um dos grandes desafios do setor. A biodigestão anaeróbia é um dos métodos mais eficazes para o tratamento de dejetos de suinoculturas. Este método de digestão, denominado UASB, tem como característica principal a produção de biogás e de biofertilizante, produto rico em nutrientes, e livre de patógenos. O método oferece vantagens como a promoção do bem estar animal, o aumento da fertilidade do solo, a diminuição da poluição e da emissão de gases geradores do efeito estufa e a melhoria da qualidade de vida, nos centros produtores de suínos, além de minimizar problemas relacionados ao déficit de energia elétrica. Portanto, a utilização de biodigestores UASB para o tratamento de dejetos de suínos é uma opção interessante, que deve ser avaliada com seriedade.

    Full Text Available A ayahuasca é uma bebida psicoativa utilizada por diversos grupos indígenas por toda a Amazônia, assim como por xamãs mestiços (chamados "vegetalistas" e por religiões e grupos independentes no Brasil. Desde a década de 1990 esta bebida vem sendo empregada no tratamento da dependência. Existem atualmente alguns centros espalhados pela América do Sul que realizam este tipo de tratamento. Realizei trabalho de campo em quatro deles, um no Peru e três no Brasil. Neste artigo faço uma pequena descrição etnográfica destes centros e teço algumas considerações sobre o papel da experiência durante o efeito do chá no processo de recuperação da dependência e também da possibilidade deste tipo de tratamento não ser uma mera terapia de substituição.

    Although the presence of PCDD/Fs in landfill leachates has been confirmed, not many experiments have been undertaken in this area, probably because of a very low solubility of PCDD/Fs in water. Modern, properly designed landfills should secure (seal) all deposited wastes and possible leakings within the damp. Leachates are collected and treated on the site or transported to a wastewater treatment plant, so they should not cause a release of any pollutants into the soil or groundwater. But PCDD/Fs as well as a number of chlorinated compounds, which may act as precursors of dioxins under aerobic or anaerobic conditions have been identified as trace contaminants in municipal wastes. The formation of dioxins during municipal waste deposition has not been studied, contrary to the formation of OCDD from precursors under aerobic conditions during composting of waste or treatment of sewage sludge5. Some information about the possible dioxin formation during landfilling might be obtained from the comparison of PCDD/F levels in the leachates from &apos;&apos;old - closed&apos;&apos; and &apos;'new'&apos; sites.

    This is the fifth Village Power workshop sponsored by NREL. We have held these meetings every year since 1993, to focus, challenge, and provide a forum for interaction among practitioners working in the field of using renewable energy technologies as an economically viable pathway to electrification of rural populations throughout the world. Starting with a small group of 30 colleagues in 1993, this &apos;'workshop'&apos; has doubled in size every year. When the NREL staff was planning for this meeting, they were hoping for something around 400 participants. We are now looking at over 500, and we apologize for the somewhat cramped accommodations. This overwhelming response, however, shows that the use of renewable energy to solve some of the world&apos;s serious problems is coming of age. This meeting, this &apos;'conference'&apos; (it&apos;s clearly no longer a workshop) marks a transition. A transition from the viewpoint that renewables are, and forever will be a technology of the future; to the reality that renewables have come of age. We have technologies available today, at today&apos;s prices, that can make a substantive contribution to the pressing needs of environmentally sustainable development in the world. This is a collection of all the papers presented at the Village Power &apos;98 conference.

    The purpose of this study is to evaluate whether patients with drug-resistant mesial temporal lobe epilepsy (TLE) due to hippocampal &apos;&apos;gliosis only&apos;&apos; have different MRI features than those with hippocampal sclerosis (HS). Most TLE patients have HS corresponding to severe neuronal loss and gliosis, but a few have &apos;&apos;gliosis only&apos;&apos; without significant reduction of neuronal density. We analyzed the morphology of cerebral 3 T MRIs (T1, T2, and FLAIR) of 103 patients with HS and 20 with &apos;&apos;gliosis only&apos;&apos; concerning hippocampal and amygdala aspect, volumes, and signal intensity (SI) using Fisher&apos;s exact test, Student&apos;s t test, and principal component analysis. Visually, the ipsilateral hippocampus was hyperintense in both groups, but SI was markedly increased in 74% of HS and in 25% of &apos;&apos;gliosis only&apos;&apos; patients; the ipsilateral hippocampus was smaller in 92% of HS and in 50% of &apos;&apos;gliosis only&apos;&apos; patients, and its internal architecture was lost in 57% of HS and 5% of &apos;&apos;gliosis only&apos;&apos; patients; the contralateral hippocampal SI was altered in 25% of HS and in 70% of &apos;&apos;gliosis only&apos;&apos; patients (all p < 0.001). Ipsilateral hippocampus of HS patients had lower volume (mean ± SD 2.86 ± 0.87 ml) compared with that of &apos;&apos;gliosis only&apos;&apos; patients (3.4 ± 1.02 ml) and had higher SI than the contralateral hippocampus of HS patients and then the hippocampus of &apos;&apos;gliosis only&apos;&apos; patients (all p < 0.01). &apos;&apos;Gliosis only&apos;&apos; has different MRI hippocampal characteristics than HS: less volume loss, less increase of the T2-w signal intensity, preservation of internal architecture, and more contralateral affection.

    The World-Climate-Summit 2016 in Paris agreed to exacerbated goals for climate protection. This paper will scrutinize whether Germany can comply with its Paris-obligations by continuing the ongoing German &apos;'Energiewende'&apos;. The result is clear-cut: The German &apos;'Energiewende'&apos; is inadequate. Due to the cap-and-trade system of the EU the &apos;'Energiewende'&apos; can in no way contribute to climate protection.

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

    Technological efficiency; Rebound; Impact; Consumption; Growth; Jevons In The Coal Question William Stanley Jevons [Jevons, W.S., 1865/1965. The Coal Question: an Inquiry Concerning the Progress of the Nation, and the Probable Exhaustion of our Coal-mines. 3rd edition 1905, Ed. A.W. Flux. Augustus M. Kelley, New York.] maintained that technological efficiency gains-specifically the more &apos;economical&apos; use of coal in engines doing mechanical work-actually increased the overall consumption of coal, iron, and other resources, rather than &apos;saving&apos; them, as many claimed. Twentieth-century economic growth theory also sees technological change as the main cause of increased production and consumption. In contrast, some ecologically-oriented economists and practically all governments, green political parties and NGOs believe that efficiency gains lower consumption and negative environmental impact. Others doubt this &apos;efficiency strategy&apos; towards sustainability, holding that efficiency gains &apos;rebound&apos; or even &apos;backfire&apos; in pursuing this goal, causing higher production and consumption. Because many environmental problems demand rapid and clear policy recommendations, this issue deserves high priority in ecological economics. If Jevons is right, efficiency policies are counter-productive, and business-as-usual efficiency gains must be compensated for with physical caps like quotas or rationing.

    To evaluate the association between vertebral &apos;&apos;end plate sclerosis&apos;&apos; and neck pain. A retrospective study was carried out of lateral cervical spine radiographs with a Picture Archive and Communication System (PACS). Two hundred patients&apos; files were randomly assessed, comprising four equal groups, A to D. The mean ages of the patients were 62{+-}7.4 years, 61{+-}7.5 years, 40{+-}5.6 years and 23{+-}5.6 years respectively. In group A, all patients had symptoms of neck pain and a radiographic diagnosis of &apos;&apos;end plate sclerosis&apos;&apos; of the cervical spine. In groups B to D, asymptomatic patients were recruited and their age groups were 50-69, 30-49 and 10-29 years respectively. Using the PACS, the radiographic density and the sagittal diameter, thickness and area of the end plates at the C5 level were measured. Results and conclusions: No significant differences were found in the radiographic density of the end plates either between the symptomatic and asymptomatic groups (groups A and B), or between different age groups (groups B, C and D). A significant increase in end plate area and thickness was found, however, in both group B (P<0.005) and group C (P<0.01) in comparison with group D. This indicates that the extent of end plate sclerosis increases with age. Our results suggest that the radiographic density of cervical vertebral end plates correlates neither with neck pain nor with increasing age. The radiological sign of &apos;&apos;end plate sclerosis&apos;&apos; may be over-reported, further limiting its value in the assessment of patients with cervical spondylosis. (orig.)

    Emotional aspects become more and more relevant and important in today&apos;s consumer world. It is not only the technical features or the price which influence decisions for buying or not, but non-tangible elements as brand name, image, imaginary value, personal positioning and other emotions. Products become more and more equal as well as their performance sets no differentiation. Therefore marketing and sales strategies call for emotional differentiations. One very successful example on today&apos;s market is the I-Pod - nothing simpler than a MP3-player which fetches three times the monetary revenue and has some times even a waiting list. Why? Because it is &apos;'cool'&apos; and a status symbol to own one. The same thinking needs to be applied in the marketing and sales activities of natural gas as a mobile fuel as well. Having many important functional disadvantages over gasoline such as a small number of filling stations, limited range of models offered and sometimes limited range and national offer, not only the financial aspects of saving fuel costs, but the emotional positioning of the buyer is very important: To be environment conscious, to be the first, to be different, to be responsible, to be looked at as a trend-setter, and to possibly have power equal to the equivalent in gasoline engines.

    Full Text Available The last war destroyed a large number of civil works, among which were the Berlin bridges. As the number of these was considerable, it was decided to improve on the original designs and methods of construction, taking advantage of new materials and prestressing techniques. Of the 84 reconstructed bridges, 24 of them have been made in prestressed concrete. This emphasizes what considerable importance was attached to this constructional method at a time when this technology had not yet reached its present day mature development. The rebuilt bridges have spans varying between 25 and 100 ms. Their foundations differ considerably in each particular case. Some consist of pile structures, others are of sheet piling, and others again are caissons. At present the most important prestressed bridge in Berlin is the Disching bridge, which runs over the Havel, and carries the road to Spandau. Its single span is 94 ms long, and the ratio of rise to span is 1/63.1.La última guerra mundial destruyó una serie de obras públicas, entre las cuales se hallaban muchos puentes de Berlín. Como el número de puentes destruidos es considerable, se pensó en mejorar las obras originales y los métodos de construcción, para lo cual se contaban con nuevos materiales y la técnica del pretensado, actualmente en estado de madurez. De las 84 obras que se han reconstruido, 24 son de hormigón pretensado. Esto pone de relieve la importancia que se le dio a este sistema en aquellos momentos en que la técnica de este tipo de construcciones no había alcanzado todavía el actual desarrollo. Los puentes reconstruidos tienen luces que varían de 25 a 100 metros. Los cimientos de estas obras son muy distintos y variados: unos están formados por tablestacas, otros se apoyan sobre pilotes y, finalmente, otros, constituidos por cajones. El puente pretensado más importante actualmente en Berlín es el de Disching, que salva el río Havel y cuyo objeto es el de dar paso a la carretera de la región de Spandau. Su único tramo tiene 94 m de luz y una relación entre flecha y luz de 1/63,1.

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.

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

    Indirect-drive targets for heavy-ion fusion must initially be heated by &apos;'foot'&apos; pulses that precede the main heating pulses by tens of nanoseconds. These pulses typically have a lower energy and perveance than the main pulses, and the fusion-chamber environment is different from that seen by later pulses. The preliminary particle-in-cell simulations of foot pulses here examine the sensitivity of the beam focusing to ion-beam perveance, background-gas density, and pre-neutralization by a plasma near the chamber entry port.

    The role of &apos;&apos;momentum removal&apos;&apos; (the drag force on the plasma ion flow) in divertor detachment is considered and analysed in detail. This analysis of the 2D modelling results shows that the drag force cannot reduce the power and particle flux to the target directly. However, it is essential for creating the conditions for efficient radiation and volumetric plasma recombination, which in turn do the job. (copyright 2015 WILEY-VCH Verlag GmbH and Co.

    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.

    Full Text Available INTRODUÇÃO: O cisto dentígero é o segundo cisto odontogênico mais frequente nos maxilares. É uma lesão benigna, derivada do epitélio odontogênico da coroa de um dente não erupcionado, porém de etiopatogenia incerta. São geralmente radiotransparentes e, mais comumente, uniloculares. Estas lesões são observadas em exames de rotina ou quando não ocorre o irrompimento de um dente permanente. Os terceiros molares inferiores e os caninos superiores são os dentes mais acometidos, sendo também alta a ocorrência desta lesão em dentes supranumerários e associados a odontomas. O cisto dentígero ocorre principalmente nas três primeiras décadas de vida, tendo um crescimento lento e assintomático; pode atingir dimensões consideráveis, causando deformidade facial, impactação e deslocamento de dentes e/ou estruturas adjacentes. OBJETIVO: Definição das técnicas de marsupialização e enucleação, bem como consideração de critérios objetivos importantes para o plano de tratamento, como tamanho do cisto, idade, proximidade com estruturas anatômicas e importância clínica do dente envolvido. Apesar das peculiaridades clínicas de cada caso e do método de tratamento escolhido, o prognóstico destas lesões é favorável, quando se emprega apropriada terapêutica. MATERIAL E MÉTODO: O presente estudo apresentará um relato de caso tratado através da manobra de descompressão seguida de enucleação, bem como uma discussão acerca das modalidades de tratamento. RESULTADO: O paciente encontra-se em pós-operatório de dois anos sem sinais de recidiva da lesão e ausência de parestesias em face. CONCLUSÃO: A técnica empregada preservou a função neurossensorial e mostrou-se eficiente para a cura da lesão.

    Full Text Available OBJETIVO: Avaliar os resultados do tratamento cirúrgico em uma série de pacientes submetidos ao tratamento prévio para megaesôfago que evoluíram com recidiva de sintomas. MÉTODO: Analisou-se os resultados das diversas técnicas operatórias realizadas em 47 pacientes pelo Serviços de Cirurgia Geral e Torácica do HMCP-PUC-Campinas. A morbidade pós-cirúrgica, mortalidade, o alívio ou nova recidiva de sintomas e o tempo de seguimento foram os principais indicadores. Dividiu-se a série em três grupos, de acordo com o grau da afecção: Incipiente (nove casos, Não-avançado (18 casos e avançado (20 casos. As técnicas operatórias utilizadas foram: à cardiomiectomia com fundoplicatura anterior, esofagocardioplastia à Tahl, esofagocardioplastia à Serra-Dória, Esofagectomia Subtotal e Mucosectomia com conservação da túnica muscular esofágica. RESULTADOS: Obteve-se índices de resolutividade satisfatórios com a técnica de cardiomiectomia com fundoplicatura para o megaesôfago Incipiente, com baixa morbidade. Nos megaesôfago não-avançado, as cardiopatias, em especial a esofagocardioplastia à Serra-Dória mostram se mais adequadas. A terapêutica do megaesôfago avançado apresentou as maiores taxas de morbidade e demonstrou superioridade das técnicas mais agressivas em relação às técnicas conservadoras, em especial a mucosectomia com preservação da túnica muscular, sendo esta a técnica com menor morbidade dentro do grupo avançado. CONCLUSÃO: A difícil padronização do tratamento cirúrgico do megaesôfago recidivado deve-se às inúmeras técnicas disponíveis, às habilidades pessoais dos cirurgiões e atenta para a criação de protocolos terapêuticos.

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

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

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

    The general structure of the spherically symmetric solutions in the Weyl conformal gravity is described. The corresponding Bach equations are derived for the special type of metrics, which can be considered as the representative of the general class. The complete set of the pure vacuum solutions is found. It consists of two classes. The first one contains the solutions with constant two-dimensional curvature scalar of our specific metrics, and the representatives are the famous Robertson-Walker metrics. One of them we called the &apos;&apos;gravitational bubbles&apos;&apos;, which is compact and with zero Weyl tensor. Thus, we obtained the pure vacuum curved space-times (without any material sources, including the cosmological constant) what is absolutely impossible in General Relativity. Such a phenomenon makes it easier to create the universe from &apos;'nothing'&apos;. The second class consists of the solutions with varying curvature scalar. We found its representative as the one-parameter family. It appears that it can be conformally covered by the thee-parameter Mannheim-Kazanas solution. We also investigated the general structure of the energy-momentum tensor in the spherical conformal gravity and constructed the vectorial equation that reveals clearly some features of non-vacuum solutions. Two of them are explicitly written, namely, the metrics à la Vaidya, and the electrovacuum space-time metrics.

    Based on the PWR spent fuel composition data measured at JAERI, two kinds of simplified methods such as &apos;&apos;Equivalent Uniform Burnup&apos;&apos; and &apos;&apos;Equivalent Initial Enrichment&apos;&apos; have been introduced. And relevant evaluation curves have been prepared for criticality safety evaluation of spent fuel storage pool and transport casks, taking burnup of spent fuel into consideration. These simplified methods can be used to obtain an effective neutron multiplication factor for a spent fuel storage/transportation system by using the ORIGEN2.1 burnup code and the KENO-Va criticality code without considering axial burnup profile in spent fuel and other various factors introducing calculated errors. &apos;&apos;Equivalent Uniform Burnup&apos;&apos; is set up for its criticality analysis to be reactivity equivalent with the detailed analysis, in which the experimentally obtained isotopic composition together with a typical axial burnup profile and various factors such as irradiation history are considered on the conservative side. On the other hand, Equivalent Initial Enrichment&apos;&apos; is set up for its criticality analysis to be reactivity equivalent with the detailed analysis such as above when it is used in the so called fresh fuel assumption.

    Continuously variable camphasers are now well established for modern spark-ignition engines in high-volume production. With the latest generation of camshaft adjustment systems using the vane-type actuator principle, it is possible to move rapidly and reliably through a large adjustment angle. The layout of these adjusting systems is very simple. The production costs are low in comparison to the first generation of camphasers using spur/helical gears to vary the valve timing. The new-generation systems are mechatronic, with the function depending on the coordination and tuning of hydraulic actuation and engine electronics. The term &apos;VaneCAM&apos; is used for the continuously variable systems of this new generation supplied by Hydraulik-Ring in Nuertingen, Germany. (orig.)

    Runnels, Scott Robert

    2015-01-01

    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.

    Overhead transmission lines are under increased public discussion. One method to minimize their influence on the environment and therefore to increase their acceptance is to camouflage lines by coating their components. Towers, conductors and fittings of a line which was erected recently in the Austrian Alps are coated in dark green colour to make the structure less visible against the background. For further reduction of visibility the line is constructed as compact line. The smaller tower size was achieved by use of short insulator strings and by oversized conductors with special advantageous mechanical properties. This paper explains the consideration which led to the configuration as compact line and for the decision to coate the complete line. It also presents long term experience with in-factory-coating of towers. Factory-coated supports were introduced 1982 in the company&apos;s network, first with the main goal to ease maintenance and second to reduce impacts on the environment. The first complete &apos;camouflage line&apos; (coloured supports and coloured conductors) in the Austrian grid was set into operation end of the year 1995. (orig.)

    Full Text Available A análise do tratamento cirúrgico de doentes portadores de pancreatite biliar mostra a existência de controvérsias em relação à oportunidade da intervenção, principalmente se deve ser precoce ou postergada. Do mesmo modo, a possibilidade do emprego de procedimentos endoscópicos no pré, intra ou pós-operatório e o advento da videolaparoscopia, trouxeram novos aspectos à discussão. Não existe consenso sobre a escolha da melhor conduta. Em função disso, analisamos retrospectivamente os resultados imediatos de 107 doentes portadores de forma leve de pancreatite, todos com menos de três sinais de gravidade, segundo o critério de estratificação proposto por Ranson, e que foram submetidos ao tratamento cirúrgico postergado na mesma internação, no período de janeiro de 1988 a maio de 1999, tanto por via convencional como por via laparoscópica. Desses, 80 doentes (75% eram do sexo feminino, 90% da raça branca e a média de idade foi de 46 anos. Os doentes foram operados em média após 9,5 dias de internação e receberam alta hospitalar após 2,9 dias, o que resultou numa permanência hospitalar média de 12,6 dias. A colangiografia intra-operatória foi realizada em 102 casos (96% e a colangiografia endoscópica pré-operatória em 24 doentes (22,4%. Os resultados mostraram incidência de coledocolitíase em 25 casos (23%, taxa de morbidade de 12% e mortalidade nula. Dos 107 casos estudados, 64 (60% foram operados pela via de acesso convencional e 43 (40% pela via laparoscópica. A comparação dos resultados entre as vias de acesso empregadas mostrou diferença estatística significante em relação ao intervalo de tempo pós-operatório, que foi menor nos doentes submetidos à via de acesso laparoscópica. Concluímos, assim, que o tratamento cirúrgico postergado de doentes portadores de pancreatite biliar na forma leve apresenta baixas morbidade e mortalidade e pode ser feito tanto pela via convencional como pela via

    Full Text Available Têm sido atribuídas à dependência de nicotina 20% das mortes nos EUA. Estudos têm mostrado que 30% a 50% das pessoas que começam a fumar escalam para um uso problemático. Nos últimos 20 anos, a educação e a persuasão não foram suficientes para promover uma mudança política, cultural e social relacionada ao comportamento de fumar. As intervenções para interromper o uso de tabaco ainda não estão integradas às rotinas dos serviços de saúde no mundo. A falta de estratégias de integração, de tempo disponível para acoplar ações assistenciais mais específicas e mesmo a percepção dos profissionais de saúde de que os tratamentos para a dependência de nicotina são pouco efetivos são algumas das barreiras apontadas. Assim, elaborar um consenso sobre a dependência de nicotina teve como objetivos: ? levantar dados epidemiológicos relevantes relacionados ao uso do tabaco no mundo e no Brasil; ? revisar as ações gerais e centrais da nicotina; ? elaborar um protocolo de triagem mínimo para serviços de atenção primária à saúde; ? recomendar diretrizes básicas de avaliação, diagnóstico e tratamento para todos os níveis de atenção à saúde em relação à dependência de nicotina; ? fornecer sugestões para a abordagem de grupos especiais de pacientes: adolescentes, gestantes, idosos, pacientes em regime de internação, obesos e pacientes com comorbidades psiquiátricas, cardiovasculares e respiratórias.

    This paper evaluates the quasi-static performance of lightweight aluminum &apos;'egg-box'&apos; panels which have an improved architecture specifically designed to increase the energy absorption capability. In its entirety, the egg-box panel structure investigated herein is made up of arrays of positive and negative frusta. To understand the collapse mechanism and the factors influencing the energy absorption thereof, compressive tests were conducted under similar test conditions on two single frusta, one constrained in situ and the other separated from the egg-box panel exposing the free-free edges. Their load-displacement histories show characteristics that are similar, with a rise in load to a point where they plateau at a steady state load for the entire collapse time. But the energy absorbed by the in situ constrained frustum is 80% greater than that separated from the egg-box panel with free-free edges. (Abstract Copyright [2010], Wiley Periodicals, Inc.)

    Observations with the Swift UV Optical Telescope have unambiguously uncovered for the first time a long-lived, UV &apos;'plateau'&apos; in a Type II-P supernova (SN). Although this flattening in slope is hinted at in a few other SNe, due to its proximity and minimal line-of-sight extinction, SN 2012aw has afforded the first opportunity to clearly observe this UV plateau. The observations of SN 2012aw revealed all Swift UV and u-band light curves initially declined rapidly, but 27 days after the explosion the light curves flattened. Some possible sources of the UV plateau are the same thermal process that causes the optical plateau, heating from radioactive decay, or a combination of both processes.

    2016-01-01

    &apos;&apos;Radiographic Testing is a NDT method to detect inherent volumetric discontinuities in materials such as castings and welds&apos;&apos; A common type of discontinuity found and most often misinterpreted and evaluated is rounded indications, whether isolated, aligned or clustered. This paper addresses the acceptance criteria of rounded indications based on various codes and standards and intends to lay at rest the confusion related to this type of discontinuity. The following are important considerations: 1. Interpretation of rounded indications based on codes and standards used in the various sectors of NDT. 2. What types of discontinuities can be regarded as rounded indications? 3. What discontinuity sizes can be regarded as relevant discontinuities? 4. What are the acceptance and rejection criteria for relevant rounded indications 5. Compiling relevant student assignments to facilitate the proper understanding of this aspect.

    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.

    Field design changed substantially from extended-field RT (EF-RT) to involved-field RT (IF-RT) and now to involved-node RT (IN-RT) and involved-site RT (IS-RT) as well as treatment techniques in radiotherapy (RT) of Hodgkin&apos;s lymphoma (HL). The purpose of this article is to demonstrate the establishment of a quality assurance program (QAP) including modern RT techniques and field designs within the German Hodgkin Study Group (GHSG). In the era of modern conformal RT, this QAP had to be fundamentally adapted and a new evaluation process has been intensively discussed by the radiotherapeutic expert panel of the GHSG. The expert panel developed guidelines and criteria to analyse &apos;'modern'&apos; field designs and treatment techniques. This work is based on a dataset of 11 patients treated within the sixth study generation (HD16-17). To develop a QAP of &apos;&apos;modern RT&apos;&apos;, the expert panel defined criteria for analysing current RT procedures. The consensus of a modified QAP in ongoing and future trials is presented. With this schedule, the QAP of the GHSG could serve as a model for other study groups. (orig.)

    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.

    Time was when a neophyte wanting to do experiments with neutrons would be told first to read D.J. Hughes&apos; classic &apos;&apos;Pile Neutron Research&apos;&apos; (1952). The book by J. Byrne is in many respects a modern equivalent, although if you were to send your student away with it, you will risk not seeing him or her again for a considerable time. What is immediately striking is that the book, rich in information and quite long, is cross-disciplinary and touches essentially all the main areas of modern physics. It covers parts of particle physics, such as the internal structure of the neutron, time-reversal violation as revealed by the (still hypothetical) electric dipole moment of the neutron, and the coupling constants for the weak interaction. From the field of basic quantum physics there are chapters on neutron optics, wave phenomena with neutrons and on the applications of these in solid-state physics. Other chapters again delve deeply into nuclear structure, nuclear reaction theory, as well as their applications: nuclear reactors and nuclear energy. At a time with specialization rampant and many physicists tending to believe that venturing outside their own cloisters is uninteresting and even dangerous, it is a pleasure to come across a book that is basically just about physics. J. Byrne of Sussex has for long been active in neutron research at the British-French-German Institut Laue-Langevin (ILL) research reactor in Grenoble, where he has worked on subjects such as weak interactions and fundamental symmetries. He has clearly intended &apos;&apos;Neutrons, Nuclei and Matter&apos;&apos; as a vade-mecum that will allow the practitioner to find the necessary information and formulas. But I believe that many others not directly engaged in neutron research will gain new insight from its many examples. To take just one case, I had not been aware of the simple physical principles that permit cold neutrons to be stored in a bottle. (The main point is that a

    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 first contribution introduces the &apos;Minergie&apos; Standard. Its application in the building and building technical services trades offers from considerable advantages and opportunities for profit. The Standard, which aims to increase the comfort and reduce the energy consumption of buildings, is introduced and the basic principles involved, including energy usage figures, are discussed. A second contribution describes two of the three main requirements for reaching the &apos;Minergie&apos; Standard, air-tightness and good thermal insulation. The main advantage of the standard - a higher level of comfort - is emphasised and an example is given. The third short article takes a look at the use of thermal solar collectors as a source of heat in &apos;Minergie&apos; buildings. A solution involving a combined solar heating and hot-water supply is discussed. The fourth contribution discusses the use of low-temperature radiators in &apos;Minergie&apos; buildings. Examples are given of heat requirements calculation and the factors involved in dimensioning the radiators are discussed. A fifth article describes a commercially available compact solar hot-water system and discusses questions of solar fraction. Returning to basic aspects, the sixth contribution introduces a labelling system for the various components of a &apos;Minergie&apos; building - such as ventilation units, insulation material, radiators, boilers etc

    The superregenerative principle has been known since the early 1920s. The circuit is extremely simple and extremely sensitive. Today, superheterodyne receivers generally supplant superregenerative receivers in most applications because there are several undesirable characteristics: poor selectivity, reradiation, etc. Superregenerative receivers undergo a revival in recent papers for wireless systems, where low cost and very low power consumption are relevant: house/building meters (such as water, energy, gas counter), personal computer environment (keyboard, mouse), etc. Another drawback is the noise level which is higher than that of a well-designed superheterodyne receiver; without an antenna input signal, the output of the receiver hears in an earphone as a waterfall noise; this sound principally is the inherent input noise amplified and detected by the circuit; however, when the input noise is negligible with respect of an antenna input signal, we are faced to an other source of &apos;noise&apos; self-generated by the superregenerative working. The main objective of this paper concerns this self-generated noise coming from an exponential growing followed by a re-injection process for which the final state is a function of the phase of the input signal.

    &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

    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.

    The experimental sensitivity to μ → e conversion will improve by four or more orders of magnitude in coming years, making it interesting to consider the &apos;'spin-dependent'&apos; (SD) contribution to the rate. This process does not benefit from the atomic-number-squared enhancement of the spin-independent (SI) contribution, but probes different operators. We give details of our recent estimate of the spin-dependent rate, expressed as a function of operator coefficients at the experimental scale.

    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.

    The &apos;'BC'&apos; size MOLICEL using the rechargeable system Li/MoS/sub 2/ has already been shown to have performance characteristics appropriate for use in an electric vehicle battery. The cell design, based on the results of thermal modelling studies, has been modified to provide for improved removal of waste heat resulting from planned high power discharge or from accidental electrical abuse. Experimental verification of the various interfacial thermal impedances was done and an appropriate heat sink specified to use air cooling for the final rejection stage. Fully instrumented 45 Ah test cells were built using a design in which waste heat was caused to flow axially in the aluminum foils forming the cathode current collector. The bottom ends of these foils were thermally integrated to the cell can bottom which had air cooling fins attached externally. Two fully charged cells of this special design were subjected to sustained short circuit whilst being cooled on their fins only with air at 25 km/h. Neither cell experienced any excessive heat built-up and no safety hazard occurred. The results show that thermal management of this type of battery can readily be done using a simple cell design modification and requiring minimum complexity for heat disposal to the environment. The system does not impose any extraordinary constraints on electric vehicle design and it would also be feasible to duct warm air from the battery heat exchanger to provide passenger compartment heating. 17 figs., 7 tabs.

    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.

    Major accidents and natural disasters with severe consequences have occurred in all sectors of industrial activity with relatively high frequency. The severe consequences of concern involve either significant loss of life or major economic loss, or both loss of life and economic loss. Such events have the last two years been referred to as &apos;black swan&apos; events following publication of Taleb&apos;s bestselling book. These events demonstrate limits to PRA application that arise from the underlying high uncertainty associated with the estimation of frequency of occurrence of such events. An approach is proposed in this paper that, consistent with the concept of defense in depth employed by the nuclear industry, augments probabilistic risk assessment with a methodology based upon &apos;threat - risk assessment&apos;. This approach shifts these very low frequency high consequence &apos;black swan&apos; events out of the probabilistic risk assessment domain into a deterministic emergency response assessment domain.

    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

    Full Text Available INTRODUÇÃO: A síndrome do impacto no ombro (SIO é uma patologia inflamatória e degenerativa que se caracteriza por impactação mecânica de determinadas estruturas que se localizam no espaço umerocoracoacromial da articulação. É a afecção mais comum da cintura escapular com prevalência superior em indivíduos com idade entre 40 e 50 anos, entretanto, por estar intimamente relacionada a algumas atividades laborais e esportivas, se torna cada vez mais frequente em adultos jovens. Mediante o elevado número de pacientes acometidos e com o intuito de orientar os diversos profissionais de saúde sobre a necessidade de tratamento precoce da patologia, é objetivo deste estudo apresentar os modelos de tratamento para SIO e a importância da fisioterapia no tratamento conservador. METODOLOGIA: Foi realizada uma revisão da literatura científica com acesso a diversas obras literárias sobre o tema e busca de artigos de periódicos nacionais e internacionais na internet. RESULTADOS: O tratamento conservador da SIO envolve um conjunto de procedimentos que passam por medidas analgésicas, anti-inflamatórias e fisioterapia, sendo a última uma ferramenta indispensável no processo de recuperação. CONCLUSÃO: Ao final do estudo pode-se concluir que o tratamento conservador é frequentemente utilizado no tratamento da SIO e a fisioterapia a modalidade terapêutica mais indicada, associada a um programa de orientação e reeducação quanto às atividades que possam dificultar o processo de recuperação plena. Contudo, o plano de tratamento depende diretamente da fase evolutiva da doença, pois, nos casos de insucesso no tratamento conservador, a cirurgia poderá ser indicada.

    Full Text Available La contaminación en los ríos de Costa Rica es un problema que merece especial atención. El concepto “contaminación del agua” implica la incorporación de materias extrañas a esta, tales como microorganis- mos (coliformes totales y fecales, productos quími- cos (jabones, fer tilizantes, pesticidas, metales pesados (cromo, plomo, mercurio, etc. o materia orgánica proveniente de los suelos a través de la escorrentía superficial y de las aguas residuales domésticas. Estas materias deterioran la calidad del agua y reducen los diferentes usos que podría tener un río. El recurso hídrico es importante tanto para la preservación de la vida humana como para la conservación de la flora y fauna. Costa Rica se ha caracterizado por ser un país poseedor de una rica biodiversidad. Sin embargo, muchos de los ríos de la Gran Área Metropolitana ya presentan una contaminación severa, según el Índice holandés de clasificación de la calidad del agua. En este estudio se analizó el contenido de colifor- mes fecales en 10 ríos de las provincias de San José, Alajuela, Heredia y Car tago, así como de la Península de Osa. Para correlacionar el contenido de colifor- mes fecales con la densidad poblacional, además, se muestrearon tres puntos en cada río: la zona alta cercana a la naciente, la zona media y la zona baja cercana a su desembocadura. Se encontró que los puntos de muestreo con densi- dades poblacionales medias o altas están altamente contaminados con coliformes fecales.Varios de ellos superan el límite máximo permisible en el contenido de coliformes fecales establecido por los reglamen- tos nacionales para el uso de los ríos en actividades de recreación de contacto primario.

    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.

    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 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.)

    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

    The aim of this paper is to outline the NDA National Graduate Programme (nuclear graduates). The NDA has a remit under the Energy Act (2004) &apos;to maintain and develop the skills for decommissioning and nuclear clean-up&apos;. Although current research is now being reviewed, there is significant evidence to suggest that the age profile in the Site Licence Companies is skewed towards older workers and there is likely to be a skill shortage in 3-5 years. As nuclear clean-up is a national issue; skill shortages also become a national issue in a very real sense. In addition, evidence suggests that the industry needs to be constantly challenged in order to achieve its targets for decommissioning. The NDA has a unique position under the Act. It is both a strategic overseer and direct employer. To this end the &apos;National Graduate Programme&apos; is aligned to both the NDA&apos;s previous succession plans and the needs of the industry. Industry needs leadership that challenges the status quo and moves the UK nuclear industry to become best in class; Industry needs a dedicated to programme to address skills shortages and difficult to recruit areas such as, but not exclusively, estimators, schedulers, contract managers, site engineers, decommissioning technicians, safety monitors; The NDA has indicated a &apos;commercial and politically savvy&apos; cohort is required to meet its own internal challenges and to ensure sustainability in its own workforce, and to be sensitive to the needs of customers and suppliers alike; Need to create a more diversified workforce in the nuclear industry and also plan for new skills evolving from research and development breakthroughs; Need to ensure that Tier 1, 2, 3 and 4 contractors invest in the leadership and skills for the future. World Class - delivery will be benchmarked against UK based multinational companies who operate in a global graduate attraction and development marketplace. The graduates targeted will be from leading

    To evaluate the variability of clinical treatment and outcomes based on reporting of diabetic foot ulcer MRI findings of adjacent marrow T2 hyperintensity with normal T1 signal. A retrospective review was conducted of 46 MRI examinations evaluating diabetic foot ulcers that demonstrated normal T1 marrow signal, but T2 marrow hyperintensity deep to the ulcer. The cohort was divided based on MRI report impressions into three groups; &apos;&apos;osteitis without osteomyelitis&apos;&apos; (OW), &apos;&apos;osteitis but cannot exclude early osteomyelitis&apos;&apos; (OCEO) and &apos;&apos;early osteomyelitis&apos;&apos; (EO). Patient demographics (age, gender) and accessory MRI findings of ulcer and sinus tract depth were recorded. Initial clinical assessment and medical treatment (route and duration of antibiotics), healing versus disease progression and histology or microbiology results were recorded. The isolated marrow T2 signal hyperintensity was reported as OW in 12 patients, OCEO in 18, and EO in 16. No statistical difference in clinical assessment was demonstrated between the OW, OCEO, and EO groups. Pathological condition was available in 15 patients within 0-7 days (mean 2.4 days) of the MRI examination, with 14 (93%) of these positive for osteomyelitis by histopathology or positive cultures. Initial diagnosis of or progression to osteomyelitis was shown in 28 patients (61%). Treatment of suspected osteomyelitis is heavily determined by clinical factors. Patients who initially demonstrate only T2 marrow signal abnormality under a diabetic ulcer are eventually diagnosed as osteomyelitis in 61% of cases and deserve aggressive treatment as early osteomyelitis when meeting clinical parameters.

    Working Committee 3&apos;s report concerns the evolution of the liquefied gas industry: both liquefied natural gas (LNG) and liquefied petroleum gases (LPG). Given the current state of the LNG market the Committee decided to concentrate on this area in particular. A number of aspects have been identified which the Committee has been looking at, while others have been given to Study Groups set up specifically for the purpose. The first aspects regard: - the development of LNG and LPG, new installations, future chains and relevant statistical data; - the role of LNG and LPG in starting up a gas industry; - operating and technological improvements in the LNG industry; - energy savings, cold utilization and reduction of CO{sub 2} emissions. The Study Groups which were set up dealt with the following subjects: Technological and Economical Developments for cost Reduction of LNG/LPG Facilities. Small Scale LNG Projects and Modular Systems. LNG/LPG Peak Shaving and Satellite Plants. LNG versus Pipeline Infrastructure. (author)

    We investigate the probability of obtaining an observable curvature perturbation, using as an example the minimal curvaton-Higgs (MCH) model. We determine &apos;probably observable&apos; and &apos;probably excluded&apos; regions of parameter space assuming generic initial conditions and applying a stochastic approach for the curvaton&apos;s evolution during inflation. Inflation is assumed to last longer than the N{sub obs}≅55 observable e-folds, and the total number of e-folds of inflation determines the particular ranges of parameters that are probable. For the MCH model, these &apos;probably observable&apos; regions always lie within the range 8 x 10{sup 4} GeV≤m{sub σ}≤2 x 10{sup 7} GeV, where m{sub σ} is the curvaton mass, and the Hubble scale at horizon exit is chosen as H{sub *}=10{sup 10} GeV. Because the &apos;probably observable&apos; region depends on the total duration of inflation, information on parameters in the Lagrangian from particle physics and from precision CMB observables can therefore provide information about the total duration of inflation, not just the last N{sub obs} e-folds. This method could also be applied to any model that contains additional scalar fields to determine the probability that these scalar fields contribute to the curvature perturbation.

    The &apos;&apos;IC 79&apos;&apos; system, which was introduced thirty years ago, has permanently moulded the shape of long-distance passenger services in Germany (with Deutsche Bundesbahn and later Deutsche Bahn). Since then, top-grade passenger trains have been running regularly every hour on several routes. They provide links with short travel times between the country&apos;s most important towns and cities. &apos;&apos;IC 79&apos;&apos; became the backbone of long-distance rail travel in Germany. The ideas underlying it and the way they were implemented are still considered exemplary today. (orig.)

(author) [Spanish] Los autores describen los trabajos de investigacion y perfeccionamiento realizados con miras a la construccion de fuentes adecuadas para el ''Irradiador de elevada intensidad para alimentos''. Los problemas que estudian son los comunes a todos los irradiadores transportables de gran tamano. La primera fase de los trabajos consistio en adquirir conocimientos mas exactos sobre las fuentes de placa y de los efectos que las variaciones de los parametros constructivos ejercen sobre el rendimiento de esas instalaciones. En primer lugar, se llevo a cabo un estudio teorico, experimental y mediante maquinas de calcular del rendimiento de los irradiadores de placa unica. Los parametros considerados han sido el tamano y la actividad especifica de la fuente, su espesor y revestimiento, la densidad del blanco y factores geometricos tales como la altura, longitud y anchura de la fuente y del blanco, asi como las dimensiones del volumen de aire que separa la fuente del blanco. Se ha estudiado el rendimiento en funcion de la capacidad del irradiador, del tiempo de exposicion, de la uniformidad de la dosis, de la eficacia de la instalacion y de los costes totales. Se han propuesto formulas simplificadas para calcular el rendimiento de los irradiadores; la validez de esas formulas se ha comprobado experimentalmente. Se ha establecido un codigo tridimensional que permite aplicar el metodo denominado de ''Monte Carlo'' al calculo del rendimiento de los irradiadores; los resultados obtenidos estan en armonia con los datos determinados por via experimental. El programa de estudio se ha extendido a los dispositivos de varias placas y de varios pasos, y abarca por consiguiente tanto las fuentes de tres dimensiones como los irradiadores de

    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

    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.

    Twenty-two volunteers who smoked more than 20 cigarettes with &apos;'high'&apos; nicotine yields (0.8 to 1.2 mg) per day participated in an 8-week study designed to test the hypothesis that smoking cigarettes with a constant level of nicotine but reduced deliveries of tar, carbon monoxide, and hydrogen cyanide leads to a decrease in smoke absorption. All subjects smoked their usual high-nicotine brand for the first 3 weeks (P1), and the absorption of smoke constituents was determined from levels of thiocyanate and cotinine in saliva and serum, levels of carbon monoxide in expired air, and levels of carboxyhemoglobin in the blood. During the final 5 weeks (P2), the treatment group (16 subjects) switched to the &apos;'light'&apos; version of their usual brands (similar yields of nicotine but with reduced yields of tar, carbon monoxide, and hydrogen cyanide); the control group (6 subjects) smoked their usual brands for the duration of the study. Average levels of cotinine for the subjects who switched during P2 were not significantly different from those of the control group as was expected. Slight reductions were noted in average expired-air carbon monoxide levels, blood carboxyhemoglobin, and saliva thiocyanate, but these reductions were smaller than anticipated based on brand characteristics. The results suggest that the ratio of smoke constituents is different when individuals, rather than machines, smoke cigarettes. Yields determined under subject-defined conditions are necessary in order to properly evaluate the role of nicotine in the design of &apos;'less-hazardous'&apos; cigarettes.

    Full Text Available Introdução - A mudança da rotina operatória para o tratamento não-operatório (TNO de traumas fechados nos órgãos abdominais sólidos é uma das tendências mais notáveis no cuidado aos pacientes politraumatizados nos últimos 14 anos. Médicos estão sentindo-se seguros para aplicar a técnica não-operatória em tais pacientes. Entretanto, surpreende-nos o fato de que, após uma mudança tão radical, nosso conhecimento seja, ainda, baseado em dados retrospectivos. Quesitos importantes, como as taxas de TNO, suas causas e fatores predisponentes foram obtidos, principalmente, através de revisões de prontuário. Objetivo - Análise da literatura científica sobre as possibilidades de tratamento não-operatório dos traumas abdominais fechados. Material e Método - A literatura científica pesquisada consta de 45 publicações de diversas revistas publicadas entre 1990 e 2004. Nosso trabalho foi realizado sob a forma de metanálise comparativa dentre as díspares condutas de tratamento dos traumas abdominais fechados. Conclusão - O trauma abdominal fechado (contuso representa parcela importante dos traumas. Seu tratamento inicialmente era cirúrgico, mas ultimamente vem-se optando pelo tratamento não-operatório, evitando-se, assim, as complicações decorrentes das cirurgias, como infecções e hemorragias. Existem, contudo, indicações adequadas para que seja realizado o tratamento não-operatório, e não existe um consenso sobre a utilização ou não dessa terapêutica em todos os casos. Diversos estudos mostram os órgãos mais afetados no trauma, os critérios de diagnóstico utilizados para identificar as lesões e as considerações sobre o monitoramento do paciente, que levarão à escolha da conduta e aos resultados do tratamento; mas as opiniões divergem.

    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)

    Diester is the French name given to the biofuel (methylic ester) made from vegetal oils (1 t of vegetal oil + 0.1 t of methanol leads to 1 t of diester + 0.1 t of glycerin). The French club of &apos;diester towns&apos; gathers all local authorities of towns that use up to 30% of diester in the diesel fuel of their vehicle fleets (buses, trucks, commercial vehicles). In March 2003, the association has opened to new members, in particular private companies which are diester users and become &apos;diester partners&apos;, in order to sustain the fight against the greenhouse effect. The consumption of 1 t of diester allows to save 2.5 t of CO{sub 2} thanks to the photosynthesis. In other words, a vehicle fueled with 30% of diester and 70% of diesel fuel reduces its greenhouse gas emissions of 23%. (J.S.)

    2015-01-16

    The Resource Description Framework (RDF) and SPARQL Protocol and RDF Query Language (SPARQL) were introduced about a decade ago to enable flexible schema-free data interchange on the Semantic Web. Today data scientists use the framework as a scalable graph representation for integrating, querying, exploring and analyzing data sets hosted at different sources. With increasing adoption, the need for graph mining capabilities for the Semantic Web has emerged. Today there is no tools to conduct "graph mining" on RDF standard data sets. We address that need through implementation of popular iterative Graph Mining algorithms (Triangle count, Connected component analysis, degree distribution, diversity degree, PageRank, etc.). We implement these algorithms as SPARQL queries, wrapped within Python scripts and call our software tool as EAGLE. In RDF style, EAGLE stands for "EAGLE &apos;Is an&apos; algorithmic graph library for exploration. EAGLE is like &apos;MATLAB&apos; for &apos;Linked Data.&apos;

    Nuclear track radiography was applied to identify aerosol &apos;hot&apos; particles which contain elements of nuclear fuel and fallout after Chernobyl NPP accident. For the determination of the content of transuranium elements in radioactive aerosols the measurement of the {alpha}-activity of &apos;hot&apos; particles by SSNTD was used in this work, as well as radiography of fission fragments formed as a result of the reactions (n,f) and ({gamma},f) in the irradiation of aerosol filters by thermal neutrons and high energy gamma quanta. The technique allowed the sizes and alpha-activity of &apos;hot&apos; particles to be determined without extracting them from the filter, as well as the determination of the uranium content and its enrichment by {sup 235}U, {sup 239}Pu and {sup 241}Pu isotopes. Sensitivity of determination of alpha activity by fission method is 5x10{sup -6} Bq per particle. The software for the system of image analysis was created. It ensured the identification of track clusters on an optical image of the SSNTD surface obtained through a video camera and the determination of size and activity of &apos;hot&apos; particles00.

    An hydraulic separation of a well and the cavern can be necessary for different workover applications, e.g. casing milling or underreaming. The separation is needed to ensure a mud circulation during such operations. In that case a barrier is set after flooding the cavern, which will then be used as a mechanical abutment for the cement bridge. If the diameter of the cavern neck has been enlarged due to e.g. unwanted leaching processes or unstabilized underreaming processes, it might get impossible to set a standard plug with the available technologies into those diameters. Therefore UGS GmbH has developed a mechanical plug, which is set hydraulically. The so called &apos;Spider Plug&apos; is used as basis for a cement bridge and can be removed by drilling after the workover has been done. Depending on the dimension of the setting tool a cavern neck up to 50&apos;&apos; diameter can be plugged by the &apos;Spider Plug&apos;. Up to now a number of successful operations on different locations has shown, that the &apos;Spider Plug&apos; is a practicable and cost-efficient solution for a mechanical abutment of large cavern necks.

    Radiomics, a recently introduced concept, describes quantitative computerized algorithm-based feature extraction from imaging data including computer tomography (CT), magnetic resonance imaging (MRT), or positron-emission tomography (PET) images. For radiation oncology it offers the potential to significantly influence clinical decision-making and thus therapy planning and follow-up workflow. After image acquisition, image preprocessing, and defining regions of interest by structure segmentation, algorithms are applied to calculate shape, intensity, texture, and multiscale filter features. By combining multiple features and correlating them with clinical outcome, prognostic models can be created. Retrospective studies have proposed radiomics classifiers predicting, e. g., overall survival, radiation treatment response, distant metastases, or radiation-related toxicity. Besides, radiomics features can be correlated with genomic information (&apos;'radiogenomics'&apos;) and could be used for tumor characterization. Distinct patterns based on data-based as well as genomics-based features will influence radiation oncology in the future. Individualized treatments in terms of dose level adaption and target volume definition, as well as other outcome-related parameters will depend on radiomics and radiogenomics. By integration of various datasets, the prognostic power can be increased making radiomics a valuable part of future precision medicine approaches. This perspective demonstrates the evidence for the radiomics concept in radiation oncology. The necessity of further studies to integrate radiomics classifiers into clinical decision-making and the radiation therapy workflow is emphasized. (orig.)

    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) [fr

    &apos;Warp drive&apos; spacetimes are useful as &apos;gedanken-experiments&apos; that force us to confront the foundations of general relativity, and among other things, to precisely formulate the notion of &apos;superluminal&apos; communication. After carefully formulating the Alcubierre and Natario warp drive spacetimes, and verifying their non-perturbative violation of the classical energy conditions, we consider a more modest question and apply linearized gravity to the weak-field warp drive, testing the energy conditions to first and second orders of the warp-bubble velocity, v. Since we take the warp-bubble velocity to be non-relativistic, v << c, we are not primarily interested in the &apos;superluminal&apos; features of the warp drive. Instead we focus on a secondary feature of the warp drive that has not previously been remarked upon-the warp drive (if it could be built) would be an example of a &apos;reaction-less drive&apos;. For both the Alcubierre and Natario warp drives we find that the occurrence of significant energy condition violations is not just a high-speed effect, but that the violations persist even at arbitrarily low speeds. A particularly interesting feature of this construction is that it is now meaningful to think of placing a finite mass spaceship at the centre of the warp bubble, and then see how the energy in the warp field compares with the mass-energy of the spaceship. There is no hope of doing this in Alcubierre&apos;s original version of the warp field, since by definition the point at the centre of the warp bubble moves on a geodesic and is &apos;massless&apos;. That is, in Alcubierre&apos;s original formalism and in the Natario formalism the spaceship is always treated as a test particle, while in the linearized theory we can treat the spaceship as a finite mass object. For both the Alcubierre and Natario warp drives we find that even at low speeds the net (negative) energy stored in the warp fields must be a significant fraction

    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.

    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.

    The US Department of Energy (DOE) laboratories have a long history of excellence in performing research and development in a number of areas, including the basic sciences, applied-energy technology, and weapons-related technology. Although technology transfer has always been an element of DOE and laboratory activities, it has received increasing emphasis in recent years as US industrial competitiveness has eroded and efforts have increased to better utilize the research and development resources the laboratories provide. This document, Technology &apos;90, is the latest in a series that is intended to communicate some of the many opportunities available for US industry and universities to work with the DOE and its laboratories in the vital activity of improving technology transfer to meet national needs. Technology &apos;90 is divided into three sections: Overview, Technologies, and Laboratories. The Overview section describes the activities and accomplishments of the DOE research and development program offices. The Technologies section provides descriptions of new technologies developed at the DOE laboratories. The Laboratories section presents information on the missions, programs, and facilities of each laboratory, along with a name and telephone number of a technology transfer contact for additional information. Separate papers were prepared for appropriate sections of this report.

    This paper reviews the trends in society, technology and energy demand of the past 30 years, together with the growth of the &apos;on-demand&apos; culture. The &apos;24/7&apos; or &apos;always on&apos; society can be defined as one where people demand-and generally receive-what they want &apos;now&apos;. It has grown up in parallel with developments in information technology, which have produced the services needed to meet that demand. Larger numbers of appliances, resulting from greater affluence and disposable income, have increased energy use, despite energy efficiencies in other areas. While monetary factors suggest that changes brought about by the 24/7 society will generally be self-correcting at the macro-economic level, there will nevertheless be effects for individuals, such as potentially severe impacts on the fuel poor as electricity prices rise. We conclude with a view of future directions. As the 24/7 culture continues to grow, there is scope for designers and for information technology to manage and reduce energy consumption. This includes buildings, their services systems, and the mix of new technologies that will be deployed over the next 20 years or so, including the possibilities for data exchange and control at the interface between energy suppliers and consumers, coupled with greater understanding of the behaviour of the consumers themselves.

    This article celebrates the successes of the Canadian independent oil contractors and the oilfield service and supply sector that keep Canada in the forefront of the world&apos;s &apos;smart&apos; nations in energy stewardship, efficiency, development, diversification and utilization. It explains how small independent contractors and service and supply enterprises play a central role on all these fronts, with supply and service companies being responsible for about 80 per cent of oil companies&apos; capital budget and 70 per cent of their operational expenditures in fields ranging from construction, and camp catering, to ambulance services, safety systems, trucking, tool making, drilling services, production testing, valve manufacturing, chemical blending and environmental protection. Special attention is paid to importance on independent contractors represented by the Small Explorers and Producers Association of Canada (SEPAC), their ability to develop or adopt new technology and to accommodate the demands of constantly changing price levels and increasingly higher expectations in terms of social responsibility, productivity and competitiveness, as well as environmental performance. As an example, the article describes the career of Robert Tessari, founder and president of Tesco Corporation, a drilling company operating in some 40 countries, who aims to automate drilling to the point where rig crews are pared to teams of two or three experts directing machinery from computer consoles. That he is well on the way of achieving his objectives is illustrated by his contributions to the development of a new generation of bits, tools and procedures known as the &apos;case drilling&apos; process which simultaneously uses the same steel tubing to make the holes into oil and gas-bearing formations and line them for production, and in so doing cut 25 to 30 per cent off the time required to drill a well and bring it to production.

    Three major genetic isoforms of apolipoprotein E (ApoE), ApoE2, ApoE3, and ApoE4, exist in humans and lead to differences in susceptibility to Alzheimer's disease (AD). This study investigated the impact of human ApoE isoforms on brain metabolic pathways involved in glucose utilization and amyloid-β (Aβ) degradation, two major areas that are significantly perturbed in preclinical AD. Hippocampal RNA samples from middle-aged female mice with targeted human ApoE2, ApoE3, and ApoE4 gene replacement were comparatively analyzed with a qRT-PCR custom array for the expression of 85 genes involved in insulin/insulin-like growth factor (Igf) signaling. Consistent with its protective role against AD, ApoE2 brain exhibited the most metabolically robust profile among the three ApoE genotypes. When compared to ApoE2 brain, both ApoE3 and ApoE4 brains exhibited markedly reduced levels of Igf1, insulin receptor substrates (Irs), and facilitated glucose transporter 4 (Glut4), indicating reduced glucose uptake. Additionally, ApoE4 brain exhibited significantly decreased Pparg and insulin-degrading enzyme (Ide), indicating further compromised glucose metabolism and Aβ dysregulation associated with ApoE4. Protein analysis showed significantly decreased Igf1, Irs, and Glut4 in ApoE3 brain, and Igf1, Irs, Glut4, Pparg, and Ide in ApoE4 brain compared to ApoE2 brain. These data provide the first documented evidence that human ApoE isoforms differentially affect brain insulin/Igf signaling and downstream glucose and amyloid metabolic pathways, illustrating a potential mechanism for their differential risk in AD. A therapeutic strategy that enhances brain insulin/Igf1 signaling activity to a more robust ApoE2-like phenotype favoring both energy production and amyloid homeostasis holds promise for AD prevention and early intervention.

    Since the introduction of ionizing radiation as a treatment and diagnostic tool in humans, scientists have been trying to estimate its side effects and potential health risks. There is now ample evidence for the principal existence of a direct relationship between higher doses and the risks of side effects. Most of the uncertainties lie in the field of low-dose effects especially with respect to the risk of cancer induction. Low-dose effects are usually of relevance in diagnostic medicine while high-dose radiation effects are typically observed after radiotherapeutic treatment for cancer or after nuclear accidents. The current state of the &apos;&apos;war of theories&apos;&apos; may be summarized as follows: one group of scientists and health regulatory officials favors the hypothesis that there is no threshold dose, i.e. the linear-no-threshold hypothesis (LNT) of radiation which can be regarded as safe. On the contrary, the critics of this hypothesis suggest that the risks of doses below 50 mSv are not measurable or even of clinical relevance and are not adequately described by a linear dose-response relationship. The aim of this article is to summarize the major unresolved issues in this field. Arguments are presented why the validity of the LNT model in the low-dose range should be regarded as at least inconsistent and is thus questionable. (orig.)

    The problems of medium protection against radioactive contamination hazards have led the Commissariat a l&apos;Energie Atomique--Service de Controle des Radiations et de Genie Radioactif to study the behavior of ions in soils. There are many theoretical researches and laboratory studies on the movement of radioelements in soil. But, with the difficulties for obtaining a similar result in field, we have developed a simple direct method of in place soil contamination. However, a principal drawback remains, the necessity to extrapolate from one or two reduced size samples to a large area. This is all the problem of sampling, which is not specific of our method. However, a choice justified by classical data, let us obtain a sufficient number of results and an accuracy which is suitable.

    In Denmark energy consultancy (demand side management activities (DSM)) took its first steps in the middle of the 80&apos;ies. The energy consultancy was built up around the Danish electric utilities on which the Danish government imposed the implementation of energy savings for funds collected through the electricity bill (approx. 0.0006 DKK/kWh corresponding to approx. 0.001 ECU). The electric utilities trained energy consultants who specialised in visiting industrial enterprises and counselling on energy consumption, primarily focusing on auxiliary systems like lighting, compressed air, ventilation and heating. Within these areas large savings could be obtained because each company was focusing on the actual production but also because the cost of energy was a fraction of the total costs. (orig.)

    A inexistência de um sistema de tratamento e distribuição de água em áreas remotas leva a população ao consumo de água de baixa qualidade, em função das ações antrópicas no nível das bacias hidrográficas. O desenvolvimento de sistemas descentralizados, que contemplem as distâncias entre residências em áreas escassamente povoadas pode proporcionar água potável, de maneira fácil, autossustentável e a baixo custo. Nesse contexto, objetivou-se o desenvolvimento de uma Estação de Tratamento de Águ...

    Full Text Available A eosinofilia sanguínea após o tratamento anti-helmíntico específico se comportou numa amostragem de 57 crianças da seguinte forma: .Na ascaridíase isolada ou associada à trieuríase a hipereosinofilia parasitária ou descia uniformemente após o tratamento, ou houve primeiro uma exacerbação que durava até a terceira semana após a erradicação da, parasitose, descendo em seguida. 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.

    Full Text Available Resumo O objetivo deste artigo é refletir sobre o uso dos objetos na direção de tratamento psicanalítico da criança autista. Primeiramente, teceremos algumas considerações a respeito da importância do objeto na constituição subjetiva, a partir da oposição freudiana entre os princípios de prazer e de realidade. A seguir, retomaremos as considerações de Frances Tustin sobre o objeto autístico e o caso Joey, de Bruno Bettelheim, para exemplificarmos como autores clássicos da psicanálise teorizaram sobre o objeto no tratamento. Por fim, discutiremos com autores contemporâneos a importância de uma retomada da noção de objeto no âmbito da teoria e da prática psicanalíticas.

    To evaluate multiparametric-MRI (mpMRI) derived histogram textural-analysis parameters for detection of transition zone (TZ) prostatic tumour. Sixty-seven consecutive men with suspected prostate cancer underwent 1.5T mpMRI prior to template-mapping-biopsy (TPM). Twenty-six men had &apos;significant&apos; TZ tumour. Two radiologists in consensus matched TPM to the single axial slice best depicting tumour, or largest TZ diameter for those with benign histology, to define single-slice whole TZ-regions-of-interest (ROIs). Textural-parameter differences between single-slice whole TZ-ROI containing significant tumour versus benign/insignificant tumour were analysed using Mann Whitney U test. Diagnostic accuracy was assessed by receiver operating characteristic area under curve (ROC-AUC) analysis cross-validated with leave-one-out (LOO) analysis. ADC kurtosis was significantly lower (p < 0.001) in TZ containing significant tumour with ROC-AUC 0.80 (LOO-AUC 0.78); the difference became non-significant following exclusion of significant tumour from single-slice whole TZ-ROI (p = 0.23). T1-entropy was significantly lower (p = 0.004) in TZ containing significant tumour with ROC-AUC 0.70 (LOO-AUC 0.66) and was unaffected by excluding significant tumour from TZ-ROI (p = 0.004). Combining these parameters yielded ROC-AUC 0.86 (LOO-AUC 0.83). Textural features of the whole prostate TZ can discriminate significant prostatic cancer through reduced kurtosis of the ADC-histogram where significant tumour is included in TZ-ROI and reduced T1 entropy independent of tumour inclusion.

    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.

    2006-09-01

    Full Text Available O tratamento do paciente com mielodisplasia deve ser feito considerando o risco biológico da doença, a idade e as condições clínicas do paciente. De um modo geral, uma doença de alto risco necessitaria de um tratamento mais agressivo. Porém, devido à elevada idade mediana no diagnóstico, a maioria dos pacientes não tolera tratamentos intensivos. O transplante de células-tronco hematopoiéticas é a única opção para aqueles que objetivam a cura da doença. Para aqueles que não podem se submeter a um transplante, as opções incluem o uso de quimioterapia intensiva, agentes hipometilantes, tratamento suportivo e/ou inclusão em estudos clínicos. A quimioterapia intensiva semelhante à utilizada para leucemia mielóide aguda é uma boa opção para pacientes em boas condições clínicas e com menos de 65 anos de idade.To initiate a treatment for myelodysplastic syndrome, the physician should consider the patient's age, status performance and the risk of transformation to acute myeloid leukemia (AML and death. In theory, a high risk disease should be approached with intense treatment however most patients are not healthy enough to receive aggressive treatment with chemotherapy or stem cell transplantation. For those who are not able to receive a transplantation, the treatment options include AML-like chemotherapy, hypomethylating agents, supportive care alone or participation in a clinical trial. AML-like chemotherapy is still a reasonable choice for those patients who are in good clinical conditions and are younger than 65 years of age.

    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.

Foram 2 utilizadas 500 aves, em delineamento inteiramente casualizado, com cinco tratamentos: Hidróxido de cálcio (500g/m ; Sulfato de Alumínio (500g/m ; Sulfato de cálcio (1000g/m ; Sulfato de cálcio 48% + Filosilicato Expandido 28% (500g/m e testemunha com quatro repetições. As amostras de cama aviária foram coletadas a cada sete dias para determinação do pH, umidade e contagem bacteriana nos meios de cultura Ágar MacConkey, Plate Count Agar (PCA. O peso das aves não se diferenciaram estatisticamente aos 42 dias, porém se observou significância na mortalidade e a conversão alimentar, entretanto em relação ao pH da cama o ideal seria após o término da segunda semana fazer nova aplicação dos produtos químicos. Todos os tratamentos foram eficazes quanto à umidade. Na contagem bacteriana com o meio PCA para mesófilas totais houve redução do desenvolvimento bacteriano, porém com o meio Ágar MacConkey para Enterobactérias totais somente o tratamento a base de Sulfato de cálcio (48% + Filosilicato expandido (28% se mostrou significativo (P < 0,05.

    2014-04-01

    Full Text Available Introdução: Apesar de ser uma neoplasia rara, o nasoangiofibroma juvenil (NAJ está associado a elevadas taxas de morbimortalidade e potencial invasão intracraniana. Excisão cirúrgica é o tratamento de escolha. O acesso endoscópico transnasal tem substituído a abordagem cirúrgica externa nas lesões pequenas, podendo ser utilizados de forma conjunta nos casos mais avançados. Objetivo: Deteminar a prevalência de complicações no tratamento cirúrgico endoscópico ou guiado por endoscopia nos NAJ com mínima invasão intracraniana. Método: Trata-se de um estudo retrospectivo realizado nos pacientes com NAJ classe IIIA de Radkowski, com mínima invasão intracraniana, submetidos à cirurgia endoscópica guiada por endoscopia ou acesso cirúrgico externo, entre janeiro de 1996 e maio de 2010. Resultados: No total, 13 pacientes foram submetidos a tratamento cirúrgico. O acesso endoscópico exclusivo foi realizado em três pacientes, sem complicações pós-operatórias. Cirurgia guiada por endoscopia foi realizada em três pacientes, com duas complicações pós-operatórias. Acesso cirúrgico externo foi realizado em sete pacientes. Conclusão: O tratamento cirúrgico do nasoangiofibroma com invasão intracraniana constitui um grande desafio a otorrinolaringologistas e neurocirurgiões. Neste aspecto, os índices de sucesso associado à baixa taxa de complicação intra e pós-operatória parecem ser indicativos de que o acesso endoscópico vem ganhando espaço no manejo do NAJ IIIA da classificação de Radkowski.

    Full Text Available Cálculos vesicais são raros e a maioria dos casos ocorre em homens adultos com obstrução infravesical. Atualmente, existem poucos dados sobre o melhor tratamento desta doença. O objetivo desta revisão foi discutir alguns aspectos da patogênese e abordar o tratamento da litíase vesical. Uma ampla pesquisa na base de dados da "National Library of Medicine"/Pubmed foi realizada com os seguintes unitermos e descritores: vesical ou bexiga associados a cálculo, pedra ou litíase, e cistolitotripsia. Cento e setenta e um artigos foram identificados. Os artigos foram avaliados independentemente por dois revisores com experiência em urolitíase. Foram incluídos quando os resultados, complicações e seguimento foram claramente reportados. No final, 32 estudos preencheram os critérios de inclusão. Nota-se que diversas opções para o tratamento da litíase vesical estão disponíveis, porém não há estudos randomizados comparando-as. Diferentes taxas de pacientes livres de cálculo são descritas, sendo: litotripsia extracorpórea com ondas de choque (75-100%, cistolitotripsia transureteroscópica (63-100%, cistolitotripsia percutânea (89-100% e cirurgia aberta (100%. O acesso percutâneo apresenta menor morbidade com resultados semelhantes ao tratamento transuretral, enquanto a litotrispsia extracorpórea apresenta as menores de taxas de eliminação de cálculos e fica reservada aos pacientes de alto risco cirúrgico.

  19. Uso do fluralaner no tratamento da demodicidose canina juvenil generalizada: relato de caso

    Directory of Open Access Journals (Sweden)

    J.A.B. Bezerra

    Full Text Available RESUMO O objetivo do presente trabalho foi relatar a eficácia do fluralaner no tratamento da demodicidose juvenil generalizada canina. Dois caninos, apresentando dois e três meses de idade, com diagnóstico clínico e parasitológico de demodicidose generalizada, foram tratados com administração única de fluralaner, na dose recomendada em bula pelo fabricante. Além disso, foi realizada a terapia adjuvante à base de xampu de peróxido de benzoíla e domperidona. Observou-se uma resposta terapêutica satisfatória, com repilação completa ao 30º dia após a administração do fármaco. Para cada paciente, foi realizado exame parasitológico do raspado cutâneo aos 75 e 90 dias seguintes ao início do tratamento, e todos foram negativos. Tendo em vista a elevada eficácia do tratamento proposto, sugere-se a inclusão do fluralaner nos protocolos terapêuticos destinados à demodicidose canina, particularmente nos pacientes pediátricos e com a forma generalizada da doença.

    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.

    The development of smart power grids is still in its infancy in Germany, in spite of extensive pilot programmes, competition from foreign power suppliers as well as unanimous opinion among experts that there is no way around them. Although a legal obligations has existed since the beginning of this year to offer &apos;'variable-load'&apos; tariffs, and despite their being desired by the political realm and having been laid down in the Energy Concept of the Federal Government, lack of consumer demand has so far inhibited the development of intelligent grids. But is it really because of the consumer, or is it more due to other parameters that Germany is threatening to lose the race in smart grid technology.

    In the European radiological early warning system about 5500 stationary sensors are actually implemented that measure continuously the local dose rate. Alongside several hundred air dust collecting systems attribute to the measurement of airborne radioactivity. The local dose rates are transmitted hourly to a central data base that is operated on behalf of the EU commission. In significantly larger time intervals the measured data of the airborne radioactivity are transmitted. In case of a cross-border radiological accident these data are the basis for recommendations given by the EU commission to the member states for national counter measures. The focus of the project &apos;&apos;Metrology for radiological early warning networks in Europe&apos;&apos; is an improvement of the metrological quality and harmonization these data and the development of improved measuring systems and evaluation methods.

    Serum amyloid P conpoent (SAP), a member of the pentraxin family, interact with pathogens and cell debris to promote their removal by macrophages and neutrophils and is co-localized with atherosclerotic plaques in patients. However, the exact mechanism of SAP in atherogenesis is still unclear. We investigated whether SAP influence macrophage recruitment and foam cell formation and ultimately affect atherosclerotic progression. we generated apoE(-/-); SAP(-/-) (DKO) mice and fed them western diet for 4 and 8 weeks to characterize atherosclerosis development. SAP deficiency effectively reduced plaque size both in the aorta (p = 0.0006 for 4 wks; p = 0.0001 for 8 wks) and the aortic root (p = 0.0061 for 4 wks; p = 0.0079 for 8wks) compared with apoE(-/-) mice. Meanwhile, SAP deficiency inhibited oxLDL-induced foam cell formation (p = 0.0004) compared with apoE(-/-) mice and SAP treatment increases oxLDL-induced foam cell formation (p = 0.002) in RAW cells. Besides, SAP deficiency reduced macrophages recruitment (p = 0.035) in vivo and in vitro (p = 0.026). Furthermore, SAP treatment enhanced CD36 (p = 0.007) and FcγRI (p = 0.031) expression induced by oxLDL through upregulating JNK and p38 MAPK phosphorylation whereas specific JNK1/2 inhibitor reduced CD36 (p = 0.0005) and FcγRI (P = 0.0007) expression in RAW cell. SAP deficiency also significantly decreased the expression of M1 and M2 macrophage markers and inflammatory cytokines in oxLDL-induced macrophages. SAP deficiency mitigated foam cell formation and atherosclerotic development in apoE(-/-) mice, due to reduction in macrophages recruitment, polarization and pro-inflammatory cytokines and inhibition the CD36/FcγR-dependent signaling pathway.

    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.

    Major accidents and natural disasters with severe consequences have occurred in all sectors of industrial activity with relatively high frequency. The severe consequences of concern involve either significant loss of life or major economic loss, or both loss of life and economic loss. Such events have in the last two years often been referred to as &apos;Black Swan&apos; events following publication of a best-selling book. The events demonstrate limits to the application of Probabilistic Risk Assessment (PRA) that arise from the underlying unquantifiable uncertainty associated with the estimation of the frequency of occurrence of such events. An approach is proposed in this paper that, consistent with the concept of defense in depth employed by the nuclear industry, augments probabilistic risk assessment with a methodology based upon &apos;threat -risk assessment&apos;. This approach shifts these very low frequency, high uncertainty, and high consequence &apos;Black Swan&apos; events out of the probabilistic risk assessment domain and into a deterministic emergency response assessment domain.

  17. The Effect of a High-Fat Diet on Brain Plasticity, Inflammation and Cognition in Female ApoE4-Knockin and ApoE-Knockout Mice.

    Directory of Open Access Journals (Sweden)

    Carola I F Janssen

    Full Text Available 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.

    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.

    In this paper we consider the dynamics of a massive spinor field in the background of the acoustic black hole spacetime. Although this effective metric is acoustic and describes the propagation of sound waves, it can be considered as a toy model for the gravitational black hole. In this manner, we study the properties of the dynamics of the fermion field in this &apos;'gravitational'&apos; rotating black hole as well as the vortex background. We compute the differential cross section through the use of the partial wave approach and show that an effect similar to the gravitational Aharonov-Bohm effect occurs for the massive fermion field moving in this effective metric. We discuss the limiting cases and compare the results with the massless scalar field case. (orig.)

    &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.

    The &apos;Bribe&apos; and &apos;Drum&apos; Affairs and suspected proliferation in connection with Transnuklear GmbH public around the turn of 1987/88. Many members of the press wished them to speed up the process of opting out of nuclear power. However, none of the accusations specifically related to nuclear power leveled at that time turned out to be tenable. Instead, all violations of the law which had been detected could have been punished in the same way as in any other branch of industry. As a consequence, the impacts arising to regulatory structures in the nuclear sector, especially the measures taken by the Federal Government, may be considered to have been unjustified in scope. The TN Affair and the associated litigation has caused a great deal of confidence in nuclear power to be lost, which now has to be reclaimed by purposeful public relations efforts. (orig.).

    &apos;Bluetooth&apos; is a new connection method for radio-connecting a short distance by means of mobile equipment including a note PC, PC peripheral equipment and portable telephone, using 2.4GHz ISM (Industrial Scientific Medical) band. It is capable of making a network without a complex operation, enabling data and audio communications. In May, 1998, an operation for deciding on the specifications was started under the leadership of five companies consisting of Ericsson, Nokia, Intel, IBM and Toshiba, with the specification version 1.0 completed in July, 1999 and opened to the public. (readable on http://www.bluetooth.com). Using such features as low power consumption, low cost and small size, the &apos;Bluetooth&apos; will be mounted on various kinds of mobile equipment and developed in mobile PAN (Personal Area Network).

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

    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.

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

    2008-07-01

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

    The US government is being pressured by both international and domestic influences to re-engage in international climate control. This paper considers whether the international &apos;pull&apos; and the domestic &apos;push&apos; will be strong enough to accomplish this. First, we discuss whether changes in the architecture of the current climate regime might induce the United States to re-engage at the international level. We argue that the United States is unlikely to rejoin any global climate regime that is based on the Kyoto architecture, even if Kyoto were to be &apos;reformed&apos;. Second, we discuss whether domestic political developments might eventually cause the United States to re-engage. We conclude that US re-engagement is likely to require the emergence of a new climate regime that basically extends US regulation to other countries. However, the forging of a unified US climate policy is still in the making. Furthermore, a new regime can gain widespread participation only if the Kyoto countries accept the idea of replacing Kyoto with some alternative architecture, which seems unlikely in the near future.

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

    Directory of Open Access Journals (Sweden)

    2015-10-01

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

The composition and structure of the complex were characterized by elemental analysis, IR, UV-vis and FAB-MS spectroscopy. The complex emits the characteristic red luminescence of Eu{sup 3+} ion due to the {sup 5}D{sub 0} {yields} {sup 7}F{sub J} (J = 0-4) transitions under {approx}395 nm-light excitation with good luminescent quantum efficiency (32%) and exhibits high thermal stability (337 deg. C). Bright red light-emitting diodes (LEDs) were fabricated by coating the complex onto a {approx}395 nm-emitting InGaN chip. When the mass ratio of the red phosphor to the silicone is 1:30, the efficiency of the fabricated LEDs with the europium complex is 0.98 lm w{sup -1}. The CIE chromaticity coordinates of the LEDs are x = 0.6057 and y = 0.3137, which are close to the National Television Standard Committee (NTSC) standard values for red color. The results indicate that the complex may act as a red component in the fabrication of near UV InGaN-based white light-emitting diodes with high color-rendering index.

    Despite the important role of apolipoprotein E (apoE) secretion from astrocytes in brain lipid metabolism and the strong association of apoE4, one of the human apoE isoforms, with sporadic and late onset forms of Alzheimer's disease (AD) little is known about the regulation of astrocytic apoE. Utilizing annotated chemical libraries and a phenotypic screening strategy that measured apoE secretion from a human astrocytoma cell line, inhibition of pan class I histone deacetylases (HDACs) was identified as a mechanism to increase apoE secretion. Knocking down select HDAC family members alone or in combination revealed that inhibition of the class I HDAC family was responsible for enhancing apoE secretion. Knocking down LXRα and LXRβ genes revealed that the increase in astrocytic apoE in response to HDAC inhibition occurred via an LXR-independent pathway. Collectively, these data suggest that pan class I HDAC inhibition is a novel pathway for regulating astrocytic apoE secretion.

    1979-03-14

    The bounty of the US is taken for granted by its population. Nowhere is this misvaluation of a society and its benefits more evident than in the energy industries. But energy represents a tool by which society can be shaped; a device by which the standared of living and the very nature of the national lifestyle can be controlled, modified, amplified, or reduced. Two examples examined to show how energy shapes social order and human life are the women&apos;s movement and the desire to live in the Sunbelt. Five phenomena are then examined to point out the desire to restrain the nation&apos;s rampant pursuit of a higher standard of living, as opposed to the more subjective and seemingly more desirable goal of a better quality of life: the civil rights movement; the environmental movement; the Vietnam War; the Watergate scandal; and the assumption that prosperity at today&apos;s level is irreducible, concrete, and not subject to diminution. The &apos;&apos;new class&apos;&apos; is essentially made up of those educated in the liberal arts, divorced from an understanding of the mechanics of free-enterprise institutions and of the sicences. The antagonistic view of the new class of corporations and its assault on established institutions are noted. Energy companies are frustrated in telling their story, but the story that must be told is not the story of how excellently the energy sector has performed, but the story of how a new breed of Americans is seeking to remake America in its own image without the rest being aware of what is going on.

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

    Full Text Available O câncer cérvico-uterino é muito comum em vários países da América Latina. As estatísticas de mortalidade e as taxas de incidência demonstram a sua real importância. O cânver cérvico-uterino freqüentemente é uma doença progressiva iniciada com mudanças intra-epiteliais, que podem se transformar em um processo invasivo, sendo o nosso objetivo tratar precocemente estas lesões quando ainda é possível a cura de 100%. Em nosso estudo prospectivo foram selecionadas 21 pacientes com neoplasia cervical intra-epitelial reatreadas pela citplogia e diagnosticadas pela histopatologia após biópsia dirigida pela colposcopia. O método terapêutico empregado foi a vaporização a laser com o CO2. Tiveram como pré-requisito os seguintes critérios: informação segura pela colposcopia da zona de transformação e afastar a presença de câncer invasivo; a neoplasia epitelial cervical deve ocupar a ectocervix sem nenhuma extensão para o canal cervical e correlação positiva entre a citologia, colposcopia e histologia. O uso de laser CO2 com microscópio permitiu precisão na aplicação e com vantagens de ser um procedimento ambulatorial diminuindo estresse cirúrgico das pacientes. Foi realizado sem anestesia e com duração média de 15 minutos. A cicatrização completou-se em torno de três semanas e com cuidados operatórios mínimos. Somente dois casos tiveram sangramento vaginal discreto no quinto e décimo dia de pós-operatório, resolvido com tamponamento vaginal por 24 horas. A colposcopia, cirurgia e o seguimento foram feitos pelo autor, tendo uma paciente sido submetida a uma segunda vaporização no quinto mês de controle. Somente uma paciente teve recidiva no 26° mês de seguimento e complementará o tratamento. As vinte outras restantes estão em controle sem recidiva de doença. Em vista dos resultados obtivemos um percentual de cura de 95%, que coincide com a literatura. O uso de laser CO2 no tratamento das neoplasias

    Different type of cooling systems can be implemented on coldness production plants. The choice very often depends on the initial investment, but from a technical and economical point of view, this choice is not necessary the best solution. Thus, it can be useful to know the different existing systems and their exploitation costs with respect to the expected needs.

  2. Adesão ao Tratamento em Gestação de Alto Risco

    Directory of Open Access Journals (Sweden)

    Fabíola Langaro

    Full Text Available No Brasil, aproximadamente 15% das gestações são de alto risco, sendo os diagnósticos de diabetes gestacional e hipertensão as causas mais frequentes dessa condição. Para a efetividade dos tratamentos indicados nesses casos, bem como alcance de desfechos favoráveis, é essencial a adesão da paciente às recomendações fornecidas pelas equipes de saúde, o que torna fundamental a avaliação desse indicador. A pesquisa apresentada avaliou a adesão de participantes de um programa de atendimento interdisciplinar a gestantes de alto risco desenvolvido em um hospital geral privado por meio de três instrumentos: Questionário Morisky-Green de adesão ao uso de medicação, Questionário de Adesão ao Tratamento e Pergunta descritiva de avaliação qualitativa. Durante oito meses, 83 gestantes responderam aos questionários, que possibilitaram identificar níveis de adesão ao longo do tempo de participação no programa, situações de não adesão mais frequentes, bem como variáveis que interferem nas medidas de adesão ao uso de medicação e ao tratamento global. Considera-se que os índices levantados são passíveis de uso como indicadores clínicos e gerenciais, possibilitando a comprovação da efetividade e melhoria constante das rotinas de saúde. Tais mecanismos são úteis para definição de protocolos, discussão de casos clínicos e mesmo para feedbackàs próprias pacientes.

    Full Text Available Os tumores da laringe e hipofaringe apresentam alta incidência no Brasil, sendo o sexto sítio mais comum entre os tumores malignos no sexo masculino. O diagnóstico inicial geralmente é realizado com lesões em estadio clínicos avançados diminuindo o sucesso do tratamento instituído. OBJETIVOS: Avaliar a evolução de 60 pacientes com carcinoma epidermóide de seio piriforme, considerando tratamento instituído, complicações e sobrevida estimada em 5 anos. FORMA DE ESTUDO: Estudo retrospectivo. MÉTODO: Os testes estatístico utilizados foram o método de Kaplan-Meier e o teste exato de Fisher. RESULTADOS: Dos 60 pacientes, 43 foram submetidos a tratamento cirúrgico seguido de radioterapia. Atualmente 27,9% estão vivos sem doença, 11,6% vivos com doença, 9,4% mortos sem doença, 34,8% mortos com doença e perda de seguimento de 16,3%. A complicação pós-operatória mais freqüente foi a fístula cutânea. A recidiva local ocorreu em 5 pacientes, regional em 6, loco-regional em 3 e metástase à distância em 6. Não houve correlação entre margem cirúrgica comprometida e sobrevida em 20 pacientes com recidiva tumoral (Teste de Fisher. Aplicando a curva de sobrevida atuarial pelo método Kaplan-Meier, obtivemos média de sobrevida em 5 anos de 23,2 meses. CONCLUSÃO: A principal complicação pós-operatória foi a fístula cutânea, sendo tratada clinicamente. A margem cirúrgica comprometida não alterou o prognóstico, apesar de ser sempre um dos princípios da cirurgia oncológica. A principal falha no tratamento foi a recidiva locorregional.

  16. Teriparatida (PTH[1-34]rh: uma nova perspectiva no tratamento da osteoporose

    Directory of Open Access Journals (Sweden)

    Oliveira Juliana Helena Abreu de

    2003-01-01

    Full Text Available No momento, as medicações aprovadas para tratamento da osteoporose agem reduzindo a taxa de perda óssea e diminuindo a reabsorção óssea. A teriparatida é um fragmento recombinante sintético de 34 aminoácidos do hormônio paratireóide humano. A teriparatida se liga ao receptor de PTH da proteína G e estimula a formação e a ação dos osteoblastos, que são as células responsáveis pela formação dos ossos. Assim, a principal diferença entre o tratamento da osteoporose com teriparatida e o tratamento anti-reabsorção é que a teriparatida promove o crescimento de osso novo. Em estudos pré-clínicos, o uso intermitente de PTH foi associado com um aumento significativo da massa óssea gradeada em diversos locais. A exposição intermitente ao PTH durante 4 a 6 semanas em modelos de animais ovariectomizados leva a um aumento da espessura do osso gradeado. Há estudos clínicos que mostram que a teriparatida aumenta significativamente a densidade óssea e diminui a incidência de fraturas osteoporóticas vertebrais e não-vertebrais nas mulheres com osteoporose pós-menopáusica e têm risco alto de fratura, e aumenta a densidade óssea nos homens com osteoporose, tanto hipogonádica como idiopática. A teriparatida é dada por injeção subcutânea diária e foi associada com um mínimo de efeitos colaterais, além de não apresentar interações medicamentosas. Sendo assim, a teriparatida surge como uma abordagem completamente nova no tratamento da osteoporose, estimulando diretamente a formação do osso.

    A classical logic exhibits a threefold inner structure comprising an algebra of propositions U, a space of &apos;truth values&apos; V, and a distinguished family of mappings {phi} from propositions to truth values. Classically U is a Boolean algebra, V = Z{sub 2}, and the admissible maps {phi}: U Z{sub 2} are homomorphisms. If one admits a larger set of maps, one obtains an anhomomorphic logic that seems better suited to quantal reality (and the needs of quantum gravity). I explain these ideas and illustrate them with three simple examples.

    2016-03-01

    Full Text Available A distonia é uma desordem de ordem neurológica, caracterizada por descontrole dos movimentos ou de posturas ou ambos, por contração intermitente ou de forma sustentada. A distonia do músico é considerada como uma distonia tarefa-específica, que é deflagrada somente durante a performance musical. Pode ocorrer em qualquer parte do corpo; frequentemente face, músculos do pescoço e membros superiores. O conhecimento dessa doença ocupacional entre a população de músicos no Brasil é pouco difundido. O objetivo deste trabalho é discorrer a respeito das estruturas cerebrais envolvidas no processo motor e da fisiologia envolvida na distonia do músico, bem como dos tratamentos disponíveis no intuito de enfatizar a importância de seu reconhecimento e tratamento precoce e apresentar pesquisa realizada com protocolo de tratamento. O método é um levantamento bibliográfico da fisiologia do controle motor, do desenvolvimento e tratamento da distonia do músico utilizando literatura nacional e internacional e aplicação de protocolo de tratamento estruturado. Como resultados, existe já um corpus bibliográfico consistente na língua inglesa, porém escasso em português, principalmente no quesito tratamento, podemos constatar melhora em diversos aspectos de padrão motor após protocolo de tratamento na avaliação após seis meses, tais como relaxamento, aquisição de maior consciência corporal ao tocar, instabilidade, tremor e dissociação de movimentos. Como conclusão, constata-se a necessidade de implementar a discussão e pesquisa nessa área, principalmente com relação aos tratamentos. Por outro lado, sabe-se que a melhor ferramenta contra esta afecção se encontra no tratamento mais precoce possível.

    Full Text Available Avaliou-se a eficácia dos tratamentos, definidos pela International Embryo Transfer Society (IETS, de oócitos bovinos, maturados in vitro e expostos experimentalmente à Leptospira interrogans sorovar Grippotyphosa. Os oócitos foram obtidos por meio de punção folicular, selecionados e distribuídos em quatro grupos, expostos ao patógeno e submetidos aos diferentes tipos de tratamentos. Foram expostos à cepa na concentração de 4,7.10(5/µL, virulenta e não adaptada ao meio de manutenção EMJH, e, de 6,3.10(5/µL, avirulenta e adaptada ao meio, por 24 horas. Os grupos tratados com tripsina ou antibióticos apresentaram eficácia de 21,7%, e o grupo lavado sequencialmente 33,4%. Os tratamentos não foram eficazes para os contaminados com a cepa avirulenta. Concluiu-se que as normas de controle de qualidade estabelecidas pela IETS poderiam ser revisadas e, possivelmente, redefinidas, uma vez que a eficácia dos tratamentos, provavelmente, não depende somente da espécie do patógeno, pois há interferência da virulência e de ação dos tratamentos sobre o tipo de patógeno.

  5. Crisis - Weisskopf&apos;s view

    International Nuclear Information System (INIS)

    Anon.

    1993-01-01

    &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

    2015-01-01

    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

  7. OPEC&apos;s strategies

    Energy Technology Data Exchange (ETDEWEB)

    Wirl, Franz [Vienna Univ. (Austria). Faculty of Business, Economics and Statistics

    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.

    It is still a challenge for the global automotive industry to build environment friendly and sustainable cars. One of the main questions is which possibilities and prospects short- and long term can be used to maintain the mobility standard today? Hybrid cars could be a short term option (such as 10 to 20 years) to serve as temporary solution. In conjunction with bio fuel hybrid cars could be a sustainable solution - but the today&apos;s availability of bio fuel doesn&apos;t cover the current and future demand of bio fuel. In this context the foodstuff production and the cultivation of monocultures shouldn&apos;t be disregarded. The enhancements of electrical components by hybrid cars allows to get access to the potential of electro mobility (middle term perspectives), even in conjunction with a fuel cell (long term perspectives). Still unresolved are the quantitative allocation of hydrogen (by renewable energy) and the infrastructure of a hydrogen system. (orig.)

    The superconducting proximity effect strongly modifies the local density of states in chaotic Josephson junctions. Recently we found that besides the well-known minigap a secondary gap appears just below the superconducting gap edge Δ in the limit of a large Thouless energy E{sub Th} >or similar Δ. To check the universality of this novel gap phenomenon we study the effect of nonideal contacts and show that the &apos;'smile'&apos;-gap crucially depends on the transmission eigenvalue distribution. In a next step we use the random matrix method to investigate the &apos;'smile'&apos;-gap. This allows us to approach the statistics of Andreev levels, going beyond the quasiclassical Greens function method. It turns out that the hard gap edge softens similar to what is already known from the minigap.

    &apos;Green&apos; building materials may be defined as being made of materials and by processes that have low impact on the environment. Linoleum is an example of a sustainable &apos;green&apos; building material. It is durable, easy to repair, is inherently antimicrobial, and has low-cost maintenance. Unlike most other floor coverings, linoleum has naturally occurring anti-static properties, making it easy to clean, since dust and dirt will not adhere to it. The ingredients in linoleum are linseed oil, resin, limestone, wood flour, pigments and jute, all obtainable from natural sources. Vibrant colours for the flooring are created by using organic pigments with no heavy metals such as lead or calcium which, consequently, pose no threat to the environment. Linoleum is also biodegradable. It can be put into a landfill, where it will decompose; in some parts of the world it is incinerated to produce electricity. When used as feedstock for electricity, used linoleum products have an energy content of 18.6 MJ/kg, which is equivalent to coal. As no toxic or corrosive gases are released, the need for gas purification is avoided.

    The series development of hybrid systems in combination with the new ZF 8-speed automatic transmissions contains also for the testing several aspects of challenge the complex overall system with additional loads, components and functions requires new definitions of testing volumes and load collectives with an ideal integration of testing expertise of all parties involved. This paper describes how, already in an early development stage of the fully hybridised 8-speed transmission system, specific load collectives have been developed with the aid of simulation. So the &apos;'hybrid-effect'&apos; as an additional load and its influence on the durability compared to non hybridised applications could be identified. Also it is shown how testing collectives have been adapted in practice to the hybrid specific needs to the point of a specific assembly of a test bench. The ZF testing concept for hybridised automatic transmissions has the ability of an early and efficient verification of the production readiness also securing highest possible series production quality for prospective hybrid projects.

    Full Text Available O fígado é o órgão mais comumente lesado nos traumatismos abdominais; no entanto, com freqüência a laparotomia revela ausência de sangramento ativo, limitando-se a intervenção à limpeza e drenagem da cavidade. Em função deste aspecto e do fato de que a maioria das lesões hepáticas é de menor gravidade, surgiu a opção do tratamento não-operatório. Esta conduta representa hoje a terapêutica de escolha nas lesões hepáticas em doentes conscientes e estáveis do ponto de vista circulatório. A experiência mostra que é um método seguro, efetivo e com excelentes resultados. Neste artigo, os autores fazem uma revisão e análise crítica do assunto, discutindo os critérios de seleção dos doentes, a avaliação e os riscos e complicações do tratamento não-operatório do trauma hepático.

  8. 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.

    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.)

    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.

    Hind feet of group of female rats aged 7, 14 and 52 weeks were X-irradiated at 20, 25 or 30 Gy. Hyperthermia (42.5/sup 0/C for 1 h) was carried out immediately following irradiation using either &apos;wet&apos; or &apos;dry&apos; heat, by immersion in water or fluorocarbon liquid. Results demonstrated that &apos;wet&apos; heat produced a consistently greater enhancement of the irradiation damage than &apos;dry&apos;. The thermal enhancement ratio for irradiation plus &apos;wet&apos; heat was approximately 1.5 and for irradiation plus &apos;dry&apos; heat 1.17 to 1.39. Immersion of the feet in fluorocarbon liquid at 37/sup 0/C did not significantly modify the irradiation response of the skin. The lower thermal enhancement ratios obtained using immersion in fluorocarbon liquid at 42.5/sup 0/C are close to those obtained in large animal studies and similar to the limited amount of data from clinical studies where microwave or ultrasound heating techniques were used. It has been demonstrated that there are large age-related differences in the response of the rat foot skin to irradiation alone. It has also been shown, using rats of the same age, that the response to irradiation plus hyperthermia was less age dependent.

Participaram do estudo 154 pessoas que faziam tratamento antirretroviral, sendo 82 homens com média de idade de 40 anos e 3 meses. Os dados foram obtidos por meio de entrevistas diretivas e por uma escala de adesão ao tratamento antirretroviral. O material textual sobre o significado do tratamento foi analisado pelo software IRAMUTEQ. O tratamento é representado a partir de duas concepções: a primeira a uma vida normal mantida pela ideia de uso contínuo e regular dos medicamentos, compartilhada pelas pessoas com alta adesão ao tratamento. Já a segunda, como algo que gera sofrimento e isolamento social, mais característica de pessoas com baixa/inadequada e insuficiente/ regular adesão. Sobre o nível de adesão, os resultados indicaram que 22.7% dos participantes apresentaram adesão alta/ estrita, e que a relação com o médico, a equipe de saúde e a informação sobre o tratamento estão relacionados com a alta/estrita adesão ao tratamento antirretroviral dos participantes.

    Several series of experiments with a FDR reactor (advanced pressurized light water reactor) were performed in 1972 in the Geesthacht critical facility ANEX. The experiments were performed to test the core prior to its usage for the propulsion of the first German nuclear merchant ship &apos;'Otto-Hahn'&apos;. In the present paper a calculational re-evaluation of the experiments is described with the use of the up-to date computer codes (Monte-Carlo code MCNP5) and nuclear data (ENDF/B-VI release 6). It is focused on the determination of uncertainties in the benchmark model of the experimental set-up, originating mainly from the limited set of information still available about the experiments. Effects of the identified uncertainties on the multiplication factor were studied. The sensitivity studies include parametric variation of material composition and geometry. The combined total uncertainty being found 0.0050 in k{sub eff}, the experiments are qualified as criticality safety benchmark experiments. (orig.)

    We report on the first successfull application of a new experimental technique to search for weakly interacting sub-eV particles (WISPs) coupling to photons. As part of the ALPS experiment located at DESY in Hamburg, this technique uses an optical resonator to enhance the power inside a HERA dipole magnet on the production side of a typical &apos;&apos;light shining through a wall&apos;&apos;-experiment. We use a frequency doubled continuous-wave laser emitting 0.6 W of power at 532 nm that is stabilized to a linear optical resonator with 8 m length. On resonance we achieve a circulating power of 34 W within the magnet. With this we obtained sensitivities corresponding to a coupling strength of g{approx}5.10{sup -7} GeV{sup -1} for interactions of axion-like particles and photons. The experimental setup and possible improvements are described and compared with common experimental designs with pulsed lasers.

    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.)

    We analyse the quantum behaviour of the &apos;&apos;Little Sibling&apos;&apos; of the Big Rip singularity (LSBR) [1]. The quantisation is carried within the geometrodynamical approach given by the Wheeler-DeWitt (WDW) equation. The classical model is based on a Friedmann-Lemaître-Robertson-Walker Universe filled by a perfect fluid that can be mapped to a scalar field with phantom character. We analyse the WDW equation in two setups. In the first step, we consider the scale factor as the single degree of freedom, which from a classical perspective parametrises both the geometry and the matter content given by the perfect fluid. We then solve the WDW equation within a WKB approximation, for two factor ordering choices. On the second approach, we consider the WDW equation with two degrees of freedom: the scale factor and a scalar field. We solve the WDW equation, with the Laplace-Beltrami factor-ordering, using a Born-Oppenheimer approximation. In both approaches, we impose the DeWitt (DW) condition as a potential criterion for singularity avoidance. We conclude that in all the cases analysed the DW condition can be verified, which might be an indication that the LSBR can be avoided or smoothed in the quantum approach

    Myxofibrosarcoma frequently shows curvilinear extensions of high T2 signal that also enhance on magnetic resonance imaging; these &apos;'tails'&apos; represent fascial extension of tumor at histopathological examination. This study was performed to determine whether the tail sign is helpful in distinguishing myxofibrosarcoma from other myxoid-containing neoplasms. The study group consisted of 44 patients with pathologically proven myxofibrosarcoma; the control group consisted of 52 patients with a variety of other myxoid-predominant tumors. Three musculoskeletal radiologists independently evaluated T2-weighted (and/or short-tau inversion recovery) and post-contrast MR images for the presence of one or more enhancing, high-signal intensity, curvilinear projections from the primary mass. Sensitivity and specificity for the diagnosis of myxofibrosarcoma were calculated for each reader. Interobserver variability was assessed with kappa statistic and percentage agreement. A tail sign was deemed present in 28, 30, and 34 cases of myxofibrosarcoma and in 11, 9, and 5 of the controls for the three readers respectively, yielding a sensitivity of 64-77 % and a specificity of 79-90 %. The interobserver agreement was moderate-to-substantial (kappa = 0.626). The tail sign at MRI is a moderately specific and sensitive sign for the diagnosis of myxofibrosarcoma relative to other myxoid-containing tumors. (orig.)

    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

A classificação da demodicose baseia-se na localização corpórea do animal, sendo localizada ou generalizada. O prognóstico é variável. Os sinais clínicos são alopecia, eritema, descamação, hiperpigmentação, liquenificação, febre e linfoadenopatia. O diagnóstico é realizado através de raspado cutâneo, impressão em fita de acetato, tricograma ou biópsia de pele. O tratamento há décadas foi realizado através do uso do amitraz, porém, além da toxicidade, o uso inadequado desse fármaco ocasionou em desenvolvimento de resistência. Atualmente, as lactonas macrocíclicas, tais como ivermectina, doramectina, milbemicina oxima e moxidectina vêm sendo empregadas com sucesso em cães. Entretanto, cães das raças dolicocéfalas, tais como Collie e Pastor Alemão, dentre outras, manifestam reações tóxicas graves com o uso da ivermectina. Assim, o objetivo desse trabalho foi relatar um caso do uso da doramectina na dose de 0,6 mg/kg, via oral a cada 72 horas, durante 60 dias no tratamento da demodicose generalizada em um cão da raça Pastor Alemão. Os resultados obtidos demostraram a melhora clínica do animal e nenhum efeito adverso foi clinicamente observado. Concluindo, não obstante a demodicose ser uma doença clínica desafiadora, o uso da doramectina demostrou vantagens pelo maior intervalo de administração, redução na duração do tratamento e a ausência de reações adversas, comuns as avermectinas quando usadas em animais dolicocéfalos.

    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 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.

    Full Text Available OBJETIVO: Relatar as recentes descobertas genéticas e moleculares, juntamente com as perspectivas futuras, para o tratamento da atrofia muscular espinhal, auxiliando, dessa forma, os profissionais da área da saúde a fazerem um rápido diagnóstico e proporcionarem um suporte terapêutico correto e precoce. FONTES DOS DADOS: As informações foram coletadas a partir de artigos científicos publicados nas duas últimas décadas, pesquisados nas bases de dados SciELO, PubMed e MEDLINE. SÍNTESE DOS DADOS: A atrofia muscular espinhal é uma doença neurodegenerativa com herança genética autossômica recessiva. É causada por uma deleção homozigótica do gene de sobrevivência do motoneurônio. Essa alteração genética resulta na redução dos níveis da proteína de sobrevivência do motoneurônio, levando à degeneração de motoneurônios alfa da medula espinhal, o que resulta em fraqueza e paralisia muscular proximal progressiva simétrica. Sabe-se que alguns cuidados básicos referentes à nutrição, respiração e fisioterapia podem ser importantes para retardar o progresso da doença e prolongar a vida dos pacientes. Vários medicamentos estão sendo testados, alguns novos, outros já conhecidos, como o ácido valproico, sendo que a paralisia pode ser estacionada, mas não revertida. CONCLUSÕES: A atrofia muscular espinhal é uma desordem de difícil diagnóstico, por ser pouco conhecida, e de tratamento ainda incerto. Os tratamentos farmacológicos e as terapias de suporte existentes ainda não são capazes de recuperar os motoneurônios ou as células musculares que já foram perdidos, mas têm o objetivo de retardar o progresso da doença e melhorar a função muscular residual dos pacientes, bem como oferecer uma melhor qualidade e expectativa de vida.

    2014-01-01

    IFDH (Intensity Frontier Data Handling), is a suite of tools for data movement tasks for Fermilab experiments and is an important part of the FIFE[2] (Fabric for Intensity Frontier [1] Experiments) initiative described at this conference. IFDH encompasses moving input data from caches or storage elements to compute nodes (the &apos;last mile&apos; of data movement) and moving output data potentially to those caches as part of the journey back to the user. IFDH also involves throttling and locking to ensure that large numbers of jobs do not cause data movement bottlenecks. IFDH is realized as an easy to use layer that users call in their job scripts (e.g. &apos;ifdh cp&apos;), hiding the low level data movement tools. One advantage of this layer is that the underlying low level tools can be selected or changed without the need for the user to alter their scripts. Logging and performance monitoring can also be added easily. This system will be presented in detail as well as its impact on the ease of data handling at Fermilab experiments.

The venue of the meeting will be the St.-Michaels-Heim a lovely place located within a garden area of Berlin-Grunewald. The ISACC 2011 is organized by the Fritz-Haber-Institute of the Max- Planck Society along with the King Saud University, Rhiyadh and by the Frankfurt Institute for Advanced Studies (FIAS), Frankfurt am Main, Germany. ISACC started as the international symposium on atomic cluster collisions in St. Petersburg, Russia in 2003. The second ISACC was held at the GSI, Darmstadt, Germany in 2007. Both first and second symposia were satellites of the International Conferences on Photonic Electronic and Atomic Collisions (ICPEAC). The third ISACC has returned to St. Petersburg, Russia in 2008. The last ISACC took place in Ann Arbor, again as a satellite meeting of the ICPEAC. Initially the symposium was mainly focused on dynamics of atomic clusters, especially in atomic cluster collisions, but since then its scope has been widened significantly to include dynamics of nanosystems, biomolecules, and macromolecules with the emphasis on the similarity of numerous essential clustering phenomena arising in different branches of physics, chemistry, and biology. After the four ISACC meetings it has become clear that there is a need for an interdisciplinary conference covering a broad range of topics related to the Dynamics of Systems on a Nanoscale. Therefore in 2010 it was decided to expand upon this series of meetings with a new conference organized under the new title &apos;&apos;Dynamics of Systems on the Nanoscale&apos;&apos;, the DySoN Conference, since this title better reflects the interdisciplinary character of the earlier ISACC meetings embracing all the topics of interest under a common theme. The first DySoN Conference took place in Rome, Italy in 2010. The fifth ISACC symposium will be again a

    This presentation made at the Swiss 2008 research conference on traffic by Robert Horbaty from the ENCO Energy Consulting AG takes a look at how the amount of renewable energy in the electricity mains and the efficiency of mobility can be increased and pollution reduced at the same time. The integration of energy supply and electrically-powered mobility to help reduce the effects of intermittent power production from renewable sources of energy is discussed. The &apos;smart&apos; technologies needed for integration and management are looked at. Examples of pilot projects are quoted and the effects of the liberalisation of the electricity markets are discussed. The advantages offered by plug-in hybrid vehicles are noted and load-shifting possibilities are discussed. Trends towards mains regulation using bi-directional charging facilities are noted.

    Primordial inflation is regarded to be driven by a phantom field which is here implemented as a scalar field satisfying an equation of state p={omega}{rho}, with {omega}-1. Being even aggravated by the weird properties of phantom energy, this will pose a serious problem with the exit from the inflationary phase. We argue, however, in favor of the speculation that a smooth exit from the phantom inflationary phase can still be tentatively recovered by considering a multiverse scenario where the primordial phantom universe would travel in time toward a future universe filled with usual radiation, before reaching the big rip. We call this transition the &apos;Big Trip&apos; and assume it to take place with the help of some form of anthropic principle which chooses our current universe as being the final destination of the time transition.

    We explore calculable models with low-energy supersymmetry where the flavor hierarchy is generated by quark and lepton compositeness, and where the composites emerge from the same sector that dynamically breaks supersymmetry. The observed pattern of Standard Model fermion masses and mixings is obtained by identifying the various generations with composites of different dimension in the ultraviolet. These &apos;single-sector&apos; supersymmetry breaking models give rise to various spectra of soft masses which are, in many cases, quite distinct from what is commonly found in models of gauge or gravity mediation. In typical models which satisfy all flavor-changing neutral current constraints, both the first and second generation sparticles have masses of order 20 TeV, while the stop mass is a few TeV. In other cases, all sparticles obtain masses of order a few TeV predominantly from gauge mediation, even though the first two generations are composite.

    Magnetic resonance imaging (MRI) was undertaken for two patients who suffered from severe cerebrovascular diseases and were clinically brain dead. The MRI system we used was Resona (Yokogawa Medical Systems, superconductive system 0.5 T) and the CT apparatus was Toshiba TCT-300. Initial CT and MRI were undertaken as soon as possible after admission, and repeated sequentially. After diagnosis of brain death, we performed angiography to determine cerebral circulatory arrest, and MRI obtained at the same time was compared with the angiogram and CT. Case 1 was a 77-year-old man who was admitted in an unconscious state. CT and MRI on the second day after hospitalization revealed cerebellar infarction. He was diagnosed as brain dead on day 4. Case 2 was a 35-year-old man. When he was transferred to our hospital, he was in cardiorespiratory arrested. Cardiac resuscitation was successful but no spontaneous respiration appeared. CT and MRI on admission revealed right intracerebral hemorrhage. Angiography revealed cessation of contrast medium in intracranial vessels in both of the patients. We found no &apos;flow signal void sign&apos; in the bilateral internal carotid and basilar arteries on MRI images in both cases after brain death. MRI, showing us the anatomical changes of the brain, clearly revealed brain herniations, even though only nuclear findings of &apos;brain tamponade&apos; were seen on CT. But in Case 1, we could not see the infarct lesions in the cerebellum on MR images obtained after brain death. This phenomenon was caused by the whole brain ischemia masking the initial ischemic lesions. We concluded that MRI was useful not only the anatomical display of lesions and brain herniation with high contrast resolution but for obtaining information on cerebral circulation of brain death.

    Full Text Available Abstract Background Apolipoprotein E (ApoE is a molecular scavenger in the blood and brain. Aberrant function of the molecule causes formation of protein and lipid deposits or "plaques" that characterize Alzheimer's disease (AD and atherosclerosis. There are three human isoforms of ApoE designated ε2, ε3, and ε4. Each isoform differentially affects the structure and function of the protein and thus the development of disease. Homozygosity for ApoE ε4 is associated with atherosclerosis and Alzheimer's disease whereas ApoE ε2 and ε3 tend to be protective. Furthermore, the ε2 form may cause forms of hyperlipoproteinemia. Therefore, introduction of ApoE ε3 may be beneficial to patients that are susceptible to or suffering from these diseases. Mesenchymal stem cells or multipotent mesenchymal stromal cells (MSCs are adult progenitor cells found in numerous tissues. They are easily expanded in culture and engraft into host tissues when administered appropriately. Furthermore, MSCs are immunosuppressive and have been reported to engraft as allogeneic transplants. In our previous study, mouse MSCs (mMSCs were implanted into the brains of ApoE null mice, resulting in production of small amounts of ApoE in the brain and attenuation of cognitive deficits. Therefore human MSCs (hMSCs are a promising vector for the administration of ApoE ε3 in humans. Results Unlike mMSCs, hMSCs were found not to express ApoE in culture; therefore a molecular screen was performed for compounds that induce expression. PPARγ agonists, neural stem cell conditioned medium, osteo-inductive media, dexamethasone, and adipo-inductive media (AIM were tested. Of the conditions tested, only AIM or dexamethasone induced sustained secretion of ApoE in MSCs and the duration of secretion was only limited by the length of time MSCs could be sustained in culture. Upon withdrawal of the inductive stimuli, the ApoE secretion persisted for a further 14 days. Conclusion The data

    1992-07-01

    This report is interested in the transitions that &apos;Chernobyl&apos; underwent in Norway. It &apos;arrived&apos; as a ghastly accident: important cultural routines were disturbed, apprehension ran high, and the country waited for scientists to &apos;repair&apos; the accident. The scourge of radiation, however, still covered much of the countryside of central Norway. Reindeer pastures were heavily polluted, and among Saami (Lapp) groups there arose a cognitive sense of disruption to a way of life. Ambivalent relations - at times cooperative, more often adversarial - developed among the Saami in respect to the outside experts who strove to bring the radiation problem under control. The report (with anthropological fieldwork) strives to show how much of the problem of &apos;Chernobyl&apos;, in this later phase, has to do with the different nature of the claims of two kinds of knowledge: the outside scientists&apos; and the Saami pastoralists.

    Full Text Available ApoE expression status was proved to be a highly specific marker of energy metabolism rate in the brain. Along with its neighbor, Translocase of Outer Mitochondrial Membrane 40 kDa (TOMM40 which is involved in mitochondrial metabolism, the corresponding genomic region constitutes the neuroenergetic hotspot. Using RNA-Seq data from a murine model of chronic stress a significant positive expression coordination of seven neighboring genes in ApoE locus in five brain regions was observed. ApoE maintains one of the highest absolute expression values genome-wide, implying that ApoE can be the driver of the neighboring gene expression alteration observed under stressful loads. Notably, we revealed the highly statistically significant increase of ApoE expression in the hypothalamus of chronically aggressive (FDR < 0.007 and defeated (FDR < 0.001 mice compared to the control. Correlation analysis revealed a close association of ApoE and proopiomelanocortin (Pomc gene expression profiles implying the putative neuroendocrine stress response background of ApoE expression elevation therein.

    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.

    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.

    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 O divertículo de Zenker (DZ é uma doença muito pouco freqüente, cujo sintoma mais importante é a disfagia cervical. Os aspectos de sua etiopatogenia ainda são motivos de várias pesquisas na literatura, através de estudos manométricos e cinerradiográficos. O tratamento mais empregado é o cirúrgico, favorecendo quase a totalidade dos doentes, com índices de recidiva muito baixos. Porém, algumas publicações enfatizam as vantagens do tratamento endoscópico. Foram revisados 39 doentes, tratados no Serviço nos últimos 15 anos, sendo que 28 foram do sexo masculino (71,8%. A idade do grupo variou de 18 a 86 anos (média 54,5 anos. Os principais sintomas foram a disfagia cervical (89,8%, a regurgitação alimentar (71,8%, a tosse repetitiva (30.7% e o emagrecimento importante (25,6%. Dois pacientes apresentaram diverticulite aguda e perfuração (5,1 %. O diagnóstico foi estabelecido através de radiografias contrastadas em 37 pacientes (94,8% e de endoscopia digestiva em 28 (71,7%. A eletromanometria foi realizada em 13 casos (33,3%. O tratamento consistiu de diverticulectomia seguida de miotomia do esfincter do músculo cricofaríngeo em 24 pacientes (61,5% e diverticulopexia seguida da mesma miotomia em 15 pacientes (38,5%. No seguimento a longo prazo de 35 pacientes (89,8%, variando de cinco meses a 12 anos (média 4,5 anos, ocorreu melhora importante com desaparecimento da disfagia em todos os casos. Três pacientes (7,7% persistiram sintomas disfágicos leves e inconstantes. Um paciente faleceu em decorrência de complicações cardíacas e pulmonares. Os estudos histopatológicos dos divertículos ressecados mostraram a presença de tumor maligno neuroendócrino em um paciente (2,5%. Os doentes submetidos a diverticulopexia receberam alta hospitalar mais precocemente.

    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.

    Full Text Available Estudos recentes têm demonstrado resultados consistentes com o uso das terapias físicas nos casos de dor e limitação de movimentos em Disfunção Temporomandibular (DTM. Dessa forma, nosso objetivo foi avaliar o efeito de dez sessões de fisioterapia, exercícios e laserterapia no tratamento da dor muscular e da artralgia em uma mulher com DTM. O alívio médio dos sintomas dolorosos obtidos por sessão foi de 20%, atingindo valor zero nas últimas semanas e mantendo-se estável por 60 dias após o término do tratamento. Os resultados demonstraram que o protocolo de tratamento utilizado foi efetivo no alívio da dor da região articular, assim como da tensão do músculo masseter, levando a paciente a reduzir a ingestão de medicamentos para controle da dor. Entretanto, estudos adicionais são necessários para se definir com maior precisão o efeito de outros programas de fisioterapia, assim como sua interação com as demais modalidades de tratamento.

    Luiz Roberto Lopes

    Full Text Available OBJETIVO: A esclerodermia é caracterizada pelo aumento fibrótico do tecido conectivo. O envolvimento esofágico atinge 75 a 90% dos pacientes. O receio em se construir uma válvula em um esôfago hipotônico levou às operações de ressecção, que têm morbidade significante. Posteriormente, estudos com técnicas anti-refluxo demonstraram regressão dos sintomas em 69 a 75% dos pacientes. MÉTODO: Sete pacientes femininas (32 a 59 anos, seguimento entre seis e 48 meses com esclerodermia apresentavam pirose e havia disfagia em seis casos. Quatro pacientes com estenoses necessitaram dilatações. Quatro pacientes foram submetidas à técnica de Nissen modificada e três pacientes à técnica de Lind, por via laparoscópica. Houve uma conversão. RESULTADOS: Todas obtiveram alguma melhora clínica, exceto uma em que houve migração da válvula. Quatro pacientes ficaram com Visick grau I (58%, uma com grau II (14%, uma com grau III (14% e uma com grau IV (14%. Não houve retardo importante do esvaziamento esofágico à cintilografia, e os exames não demonstraram mais estenoses. CONCLUSÃO: O tratamento cirúrgico anti-refluxo é eficaz em regredir os sintomas da DRGE na esclerodermia, sem comprometer a função esofágica. As ressecções são indicadas para falha do tratamento inicial, pacientes com estenoses graves ou lesões malignas.

    2007-07-01

    Full Text Available O termo bronquiectasia refere-se à dilatação anormal e irreversível dos brônquios. Atualmente, nos países desenvolvidos, onde a maior parte das bronquiectasias é atribuída a doenças sistêmicas, como a fibrose cística e as imunodeficiências primárias, têm-se observado uma diminuição progressiva da incidência dessa doença. Entretanto, em países em desenvolvimento, com menores recursos de saúde, as bronquiectasias pós-infecciosas continuam sendo um importante e freqüente problema de saúde pública. A tomografia computadorizada de alta resolução melhorou a eficácia diagnóstica nas bronquiectasias permitindo o diagnóstico mais precoce dessa entidade. A base do tratamento das bronquiectasias inclui tratar a causa específica quando possível, administrar antibióticos para tratamento da exacerbação e para supressão da carga microbiana, reduzir a excessiva resposta inflamatória, promover a higiene brônquica, controlar a hemorragia brônquica e remover cirurgicamente segmentos ou lobos extremamente danificados que possam se constituir em focos de infecção ou sangramento. Esta revisão aborda aspectos relevantes da patogênese, etiologia e diagnóstico das bronquiectasias e realiza uma atualização da terapêutica disponível.

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.

    In the Citizen Panel&apos;s Report on &apos;Electricity and Society&apos; we present the first results of three intensive week-ends. In this document, 27 Swiss citizens have recorded their opinions on the future of our electricity supply system. Solutions are sought without making claims on having found the ultimate recipe. The recommendations are the result of an assessment made by a representative cross-section of the public - one could almost say &apos;the voice of the people&apos;. They reflect not only the public&apos;s apprehensions and worries, but also their ideas and desires. (authors)

    The author presents the forgotten fact that in 1905 there were 2 restricted theories of relativity: that of Einstein and that of Poincare. These 2 theories were independently formulated, they are very close to each other but are fundamentally different when we consider their basic principles. Poincare&apos;s theory is based on a classical representation of the purely undulatory aspect of light, whereas Einstein stipulates for the quantum aspect of light. Poincare&apos;s theory implies the existence of the ether and asserts the primacy of continuity over discontinuity. The author has based his work on a thorough study of the scientific articles in which Poincare and Einstein explained their ideas. The comparison of these 2 theories sheds light on the evolution of concepts on which the whole modern physics is based. An extended bibliography of works published on special relativity or on related topics is given. (A.C.)

    &apos;Pipe navigation&apos; is a pipeline control support system which employs GIS/GPS (geographic information system/global positioning system) technology in controlling information of water pipeline and incidental facilities, using a pen note/personal computer as the operating base. These pen computers can be carried to the spot and used in displaying pipeline/incidental equipment and retrieving related information. The main features as follows:(1) Memo preparation is possible at an arbitrary place with handwriting ease. The memo data so prepared can be taken in other terminals and shared.(2) Communication with remote places is possible by transmitting drawings, prepared memo data, etc., as in facsimile (3) Confirmation of the present position and navigation are possible (GPS function), demonstrating power in a restoration work at the time of earthquake for example.(4) Inputting and maintenance of each facility information are possible through the data input support function even by general users easily.

    In his study of periodic orbits of the three-body problem, Hill obtained a formula connecting the characteristic polynomial of the monodromy matrix of a periodic orbit with the infinite determinant of the Hessian of the action functional. A mathematically rigorous definition of the Hill determinant and a proof of Hill&apos;s formula were obtained later by Poincare. Here two multidimensional generalizations of Hill&apos;s formula are given: for discrete Lagrangian systems (symplectic twist maps) and for continuous Lagrangian systems. Additional aspects appearing in the presence of symmetries or reversibility are discussed. Also studied is the change of the Morse index of a periodic trajectory upon reduction of order in a system with symmetries. Applications are given to the problem of stability of periodic orbits.

    The transition between the protostar, Class I, and the pre-main-sequence star, Class II, phases is still one of the most uncertain, and important, stages in the knowledge of the process of formation of an individual star because it is the stage that determines the final mass of the star. We observed the young stellar object &apos;'Holoea'&apos;, associated with IRAS 05327+3404, which was classified as an object in the transition between the Class I and Class II phases with several unusual properties, and appears to be surrounded by large amounts of circumstellar material. We used the SMA and BIMA telescopes at millimeter and submillimeter (submm) wavelengths to observe the dust continuum emission and the CO (1-0) and (2-1), HCO{sup +} (1-0) and (3-2), and HCN (1-0) transitions in the region around IRAS 05327+3404. We detected two continuum emission peaks at 1.1 mm: SMM 1, the submm counterpart of IRAS 05327+3404, and SMM 2, {approx}6 arcsec to the west. The emissions of the three molecules show marked differences. The CO emission near the systemic velocity is filtered out by the telescopes, and CO mostly traces the high-velocity gas. The HCO{sup +} and HCN emissions are more concentrated around the central parts of the region, and show several intensity peaks coincident with the submm continuum peaks. We identify two main molecular outflows: a bipolar outflow in an E-W direction that would be powered by SMM 1 and the other in a NE direction, which we associate with SMM 2. We propose that the SMM sources are probably Class I objects, with SMM 1 in an earlier evolutionary stage.

    The purpose of this study was to describe the imaging characteristics of subcutaneous amyloid deposits occurring at sites of insulin injection, commonly known as &apos;&apos;insulin balls,&apos;&apos; in diabetic patients on ultrasound, CT, and MRI with pathologic correlation. We retrospectively reviewed the radiographic findings of 14 lesions in 9 patients diagnosed with subcutaneous amyloid deposits at our institution between 2005-2015. Three board-certified radiologists analyzed the following: (1) the shape, size, margin, morphologic characteristics, and blood flow on US using the color Doppler signal, (2) shape, size, margin, attenuation, and presence or absence of contrast enhancement on CT, and (3) shape, size, margin, signal intensity, and presence or absence of contrast enhancement on MRI. All lesions showed ill-defined hypovascular subcutaneous nodules with irregular margins. The median diameter of lesions was 50.4 mm on US, 46.8 mm on CT, and 51.4 mm on MRI. The internal echogenicity of subcutaneous amyloid deposits was hypoechoic and heterogeneous on US. All lesions showed isodensity compared to muscle with irregular margins and minimal contrast enhancement on CT. Both T1- and T2-weighted MR images showed low signal intensity compared with subcutaneous fat. Normal diffusion and minimal contrast enhancement were seen. Subcutaneous amyloid deposits which cause insulin resistance are typically ill-defined and heterogeneous hypovascular subcutaneous nodules with irregular margins on imaging that correspond to insulin injection sites. It is also characteristic that T2WI shows low intensity compared with fat on MRI, reflective of the amyloid content. (orig.)

    Since joining the IAEA comprehensive safeguards agreements, the ROK has made some exemplary case of implementing the IAEA&apos;s safeguards policy in a State. It&apos;s the results of the ROK Government&apos;s persistent effort for nuclear transparency to maintain its peaceful nuclear activities which is indispensible in Korea. The history of the ROK SSAC development can be reflected on the trajectory of the evolution of the IAEA safeguards. The ROK SSAC has achieved technical capabilities required for IAEA safeguards, which was not possible without cooperation programme with the IAEA. The first memorable moment of the ROK-IAEA cooperation is the enhanced cooperation program for the ROK LWRs in 2001, introducing remote monitoring systems and some changes in interim inspections. The next chance for leveling the ROK SSAC up came with IS implementation. Two parties consulted what should be prepared for efficient implementation of IS through seven times working group meetings. The WG put out IS approaches which have been being applied for the ROK nuclear facilities since 2008. The IS implementation, which is based on the state level approach, allowed the ROK SSAC to get opportunities to improve more its technical capabilities about support for IAEA safeguards activities, developing verification devices and safeguards approaches for pyroprocessing related facilities. The IAEA and the ROK are putting strenuous efforts for strengthening safeguards cooperation based on the Enhanced Cooperation Arrangements which was signed in 2012, discussing the SSAC role in IAEA safeguards activities, joint use equipment, etc. Besides, two parties are considering introducing unannounced inspections at LWRs after several rehearsals. In this paper, the implication and importance of State-IAEA cooperation is presented based on the ROK&apos;s experience with summarizing the brief history of SSAC development and cooperation with the IAEA.

    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 (ΣVOCi)). 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-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.

    In April 2007, the German Weather Service (DWD) added the non-hydrostatic limited area model COSMODE to its model chain. COSMO-DE covers mainly Germany and bordering countries and has a horizontal resolution of 2.8 km (0.025 ). An advantage of the COSMO-DE is that deep convection is expected to be resolved explicitly. In order to improve the initial state of COSMO-DE an assimilation of radar derived precipitation rates is applied by using &apos;&apos;Latent Heat Nudging&apos;&apos; (LHN). The aim of LHN is to adjust the model state so that the model will respond by producing a rain rate close to the observed value. In this study, the influence of LHN on diabatic processes is investigated by evaluation of the Dynamic State Index (DSI). The DSI is calculated on both isentropic (DSI{sub {theta}}) and model levels (DSI{sub {sigma}}). To analyse the influence of LHN, model analyses with and without LHN are examined for summer 2009 (June to August). The influence of LHN is also examined in more detail in a case study of a heavy rainfall event on July 18, 2009 where a strong rainfall area was developed on the front side of a trough. Results, based on a statistical investigation and the case study, show that the model with LHN can reproduce the observed rainfall better than the runs without LHN. This is also suggested by a higher correlation between DSI and observed precipitation. The release of latent heat enhances the diabatic processes associated with the formation of additional potential vorticity anomalies resulting in stronger DSI -signals. (orig.)

    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.

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.

    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.

    Full Text Available Venous ulcer patients can experience this situation for several years without achieving healing if treatment is inadequate. Evidence-based professional practice generates effective results for patients and services. This research aimed to carry out a systematic review to assess the most effective method to improve venous return and the best topic treatment for these ulcers. Studies were collected in eight databases, using the following descriptors: leg ulcer, venous ulcer and similar terms. The sample consisted of 33 primary studies and two Meta-analyses. A wide range of treatments was identified, grouped in compression therapy (54.3% and topical treatment (45.7%. It was evidenced that compression therapy increases ulcer healing rates and should be used in patients with intact arteries. There is no consensus about the best topical treatment, although different options should be associated with compression therapy.Pacientes con úlcera venosa pueden convivir con esta situación durante varios años, sin obtener la cicatrización de la herida caso el tratamiento no sea adecuado.

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

    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

    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

    Cellulose nanocrystals have been widely studied in the materials area due to their high aspect ratio, which is directly related to a good performance as mechanical reinforcement. Obtaining this nanocrystals from commercial bleached pulps, as eucalyptus, or microcrystalline cellulose is well studied. Trying to find new extraction sources, exploring better the huge variety of Brazil’s natural fibers and giving the opportunity of development to small communities, the present work verifies the influence of two bleaching methodologies, sodium hypochlorite or hydrogen peroxide, on licuri fibers. Previous washing and mercerization steps were performed before bleaching. The product of each step was analysed by: DSC, TGA, XRD, SEM and FTIR. The yield of each step was also calculated. (author)

    It is common sense between physicists that in the beginning the cosmos is in a narrow relationship to quantum phenomena. Because of the universal validity of quantum theory this relation remains significant in the whole cosmic evolution. Whereas a classical approach is sufficient for the description of many phenomena it is no more useful at last for the case of the ground state of a system. This holds also for the cosmos. The black holes are that part of physics where quantum theory and gravitational theory come into close contact. There a Gedankenexperiment becomes possible that clarifies the fundamental role of abstract quantum information. We give it a new name (Protyposis) because it must be imagined without emitter, receiver and moreover without any concrete meaning. This meaning-free abstract quantum information is defined by means of black holes and cosmology. Protyposis enables a new conception for &apos;'matter'&apos; and makes possible to overcome the problems of the &apos;'Lego-world-view'&apos;, which result from the attempt to find the &apos;&apos;simple and therefore basic concepts&apos;&apos; in the range of spatial smallness. Matter can be understood now as &apos;&apos;formed and condensed quantum information&apos;&apos;. But on a first view it is nothing to see from its character of being information, as like matter does not appear as &apos;&apos;pure motion&apos;&apos;, what it is also because of E=mc{sup 2}.

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

    &apos;Climate change&apos; is an oft avowed environmental priority among cooperation and development actors. The Palestinian Territories, for their part, are one of the largest recipients of international aid. To the degree that the UNPD has played a role in promoting the question of &apos;climate change&apos;, the dependence of the Palestinian Authority on international aid has contributed to framing this emergent public problem; its construction is anchored in the context of the Israeli-Palestinian conflict and the Palestinian state&apos;s demand for recognition at the international level. In the international arenas dedicated to &apos;climate change&apos;, what&apos;s more, the Palestinian Authority discusses this question in terms of political and climatic injustice. Two questions thus merit study: what effect does the construction of the climate problem have on the Palestinian Authority and, conversely, what effect does the Palestinian Authority have on the construction of the climate problem?

Those in positions of power and influence in one country should take care to be as responsible in their dealings with their neighbours as they are in handling domestic matters of state. Those who see &apos;danger&apos; where there is none are not being good neighbours. They are generating fear and alarm without good cause and should mind their own business.

    &apos;&apos;Cold fusion is dead, isn&apos;t it?&apos;&apos; is a question I am often asked. The reply is a strange one, &apos;&apos;Yes, scientifically it is dead, but not from a media point of view or from funding&apos;&apos; In 1989 two electrochemists, Martin Fleischmann and Stanley Pons, claimed sustained nuclear fusion had been achieved in a test-tube with a palladium cathode and deuterium, observing excess heat, neutrons and tritium. A series of encouraging confirmations and successively greater excess heat claims were seized on by the world&apos;s media. The US Government set up a panel of some 20 world-class scientists from several disciplines under John Huizenga, distinguished professor of Chemistry and Physics at the University of Rochester. They concluded that there was no present evidence for the discovery of a new nuclear process termed cold fusion. It might be thought that would end cold fusion, but for interesting reasons, it did not entirely. John Huizenga has written a book describing the curious claims and evidence for cold fusion and has given an excellent explanation of the science involved. This was published as a hardback book of 236 pages, telling the story up to the end of June 1990. Again one might think it was the end of the cold fusion story. Now he has written about what happened in the next two years in a paperback book which contains an epilogue of 51 pages. If you thought the first year was extraordinary, the next two years described in the new edition were even more incredible! In the main part of the book, the basic science is simply and clearly explained. The number of &apos;'miracles'&apos; required for each results or theory is described - a &apos;'miracle'&apos; is a gross violation of previous knowledge and experimental results such as energy conservation. Thus some theories are classified as &apos;&apos;triple miracles&apos;&apos;. It might be thought that people who claimed to have observed cold fusion

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.

    Due to the global climate change, the power industry has a lot of changes in store. For reasons of environmental protection, the reduction in CO{sub 2} emissions in power generation and loss minimization in power transmission are of particular importance. This means that the share of wind power in a lot of countries, Germany among them, must be as high as possible, for the other &apos;'green'&apos; energy resources, such as hydro or solar power, play only a subordinate part for reasons of their geographical location. Along with sustainability and efficiency of power supply, grid security must be taken into account as well. (orig.)

    One of the key ingredients of Connes&apos;s noncommutative geometry is a generalized Dirac operator which induces a metric (Connes&apos;s distance) on the pure state space. We generalize such a Dirac operator devised by Dimakis et al, whose Connes distance recovers the linear distance on an one-dimensional lattice, to the two-dimensional case. This Dirac operator has the local eigenvalue property and induces a Euclidean distance on this two-dimensional lattice, which is referred to as &apos;natural&apos;. This kind of Dirac operator can be easily generalized into any higher-dimensional lattices. (author)

    The &apos;&apos;Cobalt 60 Case&apos;&apos; in Taiwan gives an opportunity for check of the thesis of radiation hormesis. Apartment residents have been exposed to cobalt-60 contaminated steel buildings. The results of a study strongly suggest that whole-body chronic irradiation, in the dose rate range that the apartment residents received, caused no symptomatic adverse health effects, such as radiation sickness, or the increased cancer or increased congenital disease that are predicted by ICRP theories. On the contrary, those who were exposed had lower incidences of cancer mortality and congenital malformations.

    A system of automated processing of seismic data is examined which makes it possible to set up rate functions at arbitrary points of a seismic prospecting section or at points conciding with boreholes in which rate measurements have not been completed. The basis for the forecasting method is data on seismic well logging investigations, seismic prospecting and some indirect observations on sections. The bases of a procedure realizing a forecasting method are set forth, as are those requirements which satisfy the system as a whole. The results of using the &apos;'section'&apos; system in a terrestrial section of Western Siberia are set forth.

    This workshop is concerned primarily with the effects of biotic factors on forest decline. The possible involvement of viruses, mycoplasma-like organisms (MLO), rickettsia-like bacteria (RLB), fungi, insects and nematodes in diseases and pests of forest trees has to be investigated. Beside abiotic factors these agents are the cause of different die-back symptoms and damage of trees, but it is not yet known to what extent they contribute to the symptoms man associate with the forest decline &apos;'Waldsterben'&apos;.

    Tracheo-bronchial injuries occur in less than 1 % of blunt chest trauma patients. Indirect signs, such as pneumomediastinum, pneumothorax, and/or subcutaneous emphysema, are revealed on admission plain films and chest CT survey. In most instances, however, tracheo-bronchoscopy is mandatory in assessing the definite diagnosis of tracheo-bronchial lesion. Occasionally, an abnormal course of a mainstem bronchus or a &apos;&apos;fallen lung&apos;&apos; sign, featuring a collapsed lung in a dependent position, hanging on the hilum only by its vascular attachments, may allow for CT diagnosis of a blunt traumatic bronchial injury.

    Full Text Available Ginecomastia é o aumento da mama masculina que pode acometer até 65% dos indivíduos deste sexo na fase infanto-puberal, compreendida entre 13 e 16 anos. Tem como principais causas hepatite ou cirrose hepática, carcinoma ou doenças inflamatórias pulmonares crônicas, carcinomas ou disfunções testiculares, tumores glandulares (pituitária, supra-renal, alterações dos níveis séricos de testosterona, síndromes genéticas (síndrome de Klinefelter, p.ex., uso de drogas como heroína, maconha ou anabolizantes e hanseníase. Podemos classificar a ginecomastia quanto ao volume, quanto aos tecidos que a compõem (gordurosa ou pseudoginecomastia, glandular e mista, ou quanto ao tratamento necessário para sua correção cirúrgica (pequena, moderada e grave. O tratamento das formas mais graves de ginecomastia é muito diferente daquele aplicado às formas mais suaves, pois nas formas graves, além da ressecção dos tecidos gorduroso e glandular, existe a necessidade de ressecção da pele em excesso e o reposicionamento do complexo aréolo-mamilar. O objetivo deste trabalho é descrever uma técnica cirúrgica específica para estes pacientes portadores de formas graves de ginecomastia, através de dois pedículos dermogordurosos, um lateral e um medial, com aproximadamente 2cm de espessura, mantendo assim a nutrição do complexo aréolo-mamilar. Esses pedículos são delimitados entre as bissetrizes dos quadrantes súpero-lateral e ínfero-lateral, e súpero-medial e ínfero-medial, tendo o mamilo como vértice. Na área de pele excessiva periareolar, obtida através do pinçamento interdigital, é realizada a desepidermização dos pedículos lateral e medial e ressecção de toda pele e tecido celular subcutâneo até a fáscia peitoral nas regiões superior e inferior aos pedículos; a síntese é realizada em dois planos, sendo periareolar a cicatriz resultante. Foram operados com esta técnica vinte pacientes com forma grave de

    Full Text Available O autor inicia o trabalho referindo as bases bioquímicas, fisiopatológicas e anátomo-patológicas do tratamento da miastenia pelo ACTH. Na miastenia grave há diminuição da síntese da acetilcolina no organismo, atuando o ACTH no sentido de aumentar esta síntese seja diretamente, por ativação da colinacetilase, seja indiretamente, mediante a redução da massa dos tecidos linfóides, em particular do timo, responsáveis pela elaboração de substâncias que diminuem a síntese da acetilcolina. O autor empregou o ACTH "Armour" e a Cortrofina "Organon", nas doses de 2,5 a 25 mg, sempre pela via intravenosa, diluídos em 250 a 1.000 ml de soluto glicosado a 5%, administrado gota a gôta, na velocidade média de 20 gôtas por minuto, durante 8 horas. Como medicação associada foi administrada a Prostigmina a todos os pacientes, substituída, depois, em alguns casos, pelo Mestinon ou pela Mytelaze. Como adjuvantes foram empregados o cloreto de potássio (2 a 8 g por dia e o sulfato de efedrina (25 mg 3 vêzes ao dia. Os pacientes foram mantidos em regime hiperprotéico e acloretado, sendo tomados todos os cuidados inerentes ao uso do ACTH. Foram estudados 10 pacientes portadores de miastenia com sintomatologia acentuada (8 casos e média (2 casos. Todos os doentes vinham sendo tratados com drogas anticolinesterásicas em doses adequadas (Prostigmina, Mestinon, Mytelaze e a sua sintomatologia respondia cada vez menos a esta terapêutica. Em alguns casos haviam sido tentados outros tratamentos (timectomia, denervação do seio carotídeo, irradiação da região tímica sem resultado. É de notar que as remissões espontâneas neste grupo de enfermos foram excepcionais e de curta duração. A evolução foi acompanhada do ponto de vista clínico, com a sintomatologia classificada como muito acentuada, acentuada, média e leve. Em todos os casos houve remissão completa ou quase completa da sintomatologia após dosagens variáveis de ACTH; no

    Full Text Available Na última década, devido ao desenvolvimento das técnicas de derivação ventrículo-venosa, aumentou consideravelmente o interesse pelo tratamento cirúrgico da hidrocefalia. Entretanto, com o tempo, foram sendo observadas complicações que fizeram arrefecer o entusiasmo inicial de alguns cirurgiões. Julgamos oportuno, por isso, fazer uma avaliação dos resultados obtidos em uma série de 136 crianças hidrocefálicas operadas entre dezembro de 1958 e dezembro de 1965, e nas quais foi feita derivação ventrículo-atrial. Das crianças operadas, 72 estão vivas e com a hidrocefalia compensada e 30 faleceram, não sendo possível estabelecer as condições atuais das 34 restantes. A análise das condições pré-operatórias, das complicações e dos resultados finais permitiram algumas conclusões: 1 é pequena a ocorrência de manifestações clínicas de tromboembolismo pulmonar, no pós-operatório da ventrículo-atriostomia, justificando-se o uso destas derivações, enquanto não se desenvolverem formas mais eficazes de tratamento da hidrocefalia; 2 exames cardiológicos repetidos devem ser feitos em doentes submetidos às derivações ventrículo-atriais, a fim de permitir o diagnóstico precoce de sobrecarga do coração direito; 3 com enérgico tratamento das complicações infecciosas, progresso das técnicas de assepsia e seleção cuidadosa dos casos, os resultados tendem a melhorar; 4 o médico que trata hidrocefálicos deve prevenir os familiares a respeito da possível necessidade de novos atos cirúrgicos, devendo estar preparado para reintervir tantas vezes quantas forem necessárias; 5 não é justificada a conduta de trocar o catéter atrial sempre que a extremidade do mesmo atinge o nível da quarta vértebra torácica, como recomendam alguns cirurgiões; 6 não é justificada a afirmação de que uma criança submetida à ventrículo-atriostomia necessite permanecer sempre com a drenagem funcionando; 7 para avaliar o

    International Nuclear Information System (INIS)

    2017-01-01

    We study in some detail the properties of the mathematically correct formulation of the classical Einstein-Rosen &apos;bridge&apos; as proposed in the original 1935 paper, which was shown in a series of previous papers of ours to represent the simplest example of a static spherically symmetric traversable lightlike thin-shell wormhole. Thus, the original Einstein-Rosen &apos;bridge&apos; is not equivalent to the concept of the dynamical and non-traversable Schwarzschild wormhole, also called &apos;Einstein-Rosen bridge&apos; in modern textbooks on general relativity. The original Einstein-Rosen &apos;bridge&apos; requires the presence of a special kind of &apos;exotic&apos; matter source located on its throat which was shown to be the simplest member of the previously introduced by us class of lightlike membranes. We introduce and exploit the Kruskal-Penrose description of the original Einstein-Rosen &apos;bridge&apos;. In particular, we explicitly construct closed timelike geodesics on the pertinent Kruskal-Penrose manifold.

    Complex simulation suite &apos;Virtual Unit of NPP&apos; (CSS &apos;VEB&apos;) is a set of connected software tools and computer codes that allow the simulation of various physical processes occurring in a power nuclear reactor (initially VVER - pressurized water reactor). A coupled computational model developed by means of CSS &apos;VEB&apos; is based on a specific design and called an NPP Virtual Power Unit (VPU). And in November 2012 a pilot version of the Leningrad NPP-2 VPU (NPP-2006 design with water-cooled power reactor) successfully passed acceptance tests. The paper presents further development of CSS &apos;VEB&apos; and application area expansion both on new tasks such as VPU calculations for the Probability Safety Analysis (PSA) and all modeling of other NPP types, like sodium-cooled reactor (that means a possibility to create a VPU not only for NPP with PWR). In the first part of this paper we will recall the basic idea and concept of CSS &apos;VEB&apos; and VPU. Then we will describe the main components of CSS &apos;VEB&apos; and their improvements.

    Full Text Available RESUMO: A utilização de bioestimulantes pode auxiliar a mitigar os prejuízos ao milho, ocasionados pela má qualidade de estande. Este trabalho foi conduzido objetivando avaliar o efeito do tratamento de sementes com bioestimulante sobre o desempenho agronômico do milho, submetido a diferentes níveis de variabilidade na distribuição espacial das plantas na linha de semeadura. O experimento foi implantado em Lages, SC, durante o ano agrícola de 2013/2014. O delineamento experimental foi de blocos ao acaso, dispostos em parcelas subdivididas. Nas parcelas principais, testaram-se três níveis de desuniformidade espacial na linha: 0, 50 e 100% do Coeficiente de Variação (CV. No nível 0 % de CV, todas as sementes foram uniformemente distribuídas no sulco de semeadura, a uma distância de 17cm entre si. Nos demais níveis de CV, as distâncias entre sementes variaram conforme o tratamento. Nas subparcelas, testou-se a presença ou ausência do tratamento de sementes com bioestimulante. O aumento da variabilidade na distribuição espacial das plantas reduziu a área foliar e o teor de clorofila da folha índice no espigamento, bem como o diâmetro do colmo na colheita, independentemente do tratamento de sementes com bioestimulante. Isso contribuiu para reduzir o número de grãos por espiga e o rendimento de grãos dos tratamentos com 50 e 100% de CV na variabilidade espacial, tanto na presença quanto na ausência do bioestimulante. Portanto, o tratamento de sementes com bioestimulante não mitigou os prejuízos ao rendimento de grãos do milho ocasionados pela distribuição espacial irregular das plantas na linha de semeadura.

    Full Text Available Electroconvulsive therapy is known to be effective in the treatment of mood disorders, more specifically for depression and mania. Although a large body of evidence confirms the efficacy of electroconvulsive therapy in the treatment of mania, few prospective studies have been done to assess its effectiveness in treatment-resistant manic episodes. These case reports describe the initial results of a study that is being conducted to evaluate the efficacy of Electroconvulsive therapy among treatment-resistant bipolar patients. METHODS: Three manic patients (according to DSM-IV criteria who were considered treatment-resistant underwent a series of 12 bilateral Electroconvulsive therapy sessions. Before the treatment and then weekly, they were evaluated with the following rating scales: Young Mania Rating Scale, Hamilton Rating Scale for Depression, Brief Psychiatric Rating Scale, and Clinical Global Impressions-Bipolar Version. RESULTS: The 3 patients showed a satisfactory response to Electroconvulsive therapy, although some differences in the course of response were observed. CONCLUSION: These case reports suggest that Electroconvulsive therapy needs further evaluation for the treatment of resistant bipolar patients.A Eletroconvulsoterapia é uma alternativa reconhecidamente eficaz no tratamento dos transtornos do humor.

  9. O ultrassom é efetivo no tratamento da tendinite calcárea do ombro?

    Directory of Open Access Journals (Sweden)

    Josiane Sena dos Santos

    Full Text Available Introdução: A tendinite calcária do ombro é uma calcificação caracterizada pela deposição de sais de cálcio nos tendões do manguito rotador, provocando dor no ombro e perda de amplitude de movimento (ADM. O ultrassom é sugerido como alternativa promissora para facilitar a reabsorção dos depósitos de cálcio. Os mecanismos que fundamentam esse efeito são, entretanto, ainda controversos na literatura, e a utilização clínica do ultrassom na tendinite calcária tem sido baseada mais em evidências empíricas do que científicas. Objetivos: Realizar uma revisão bibliográfica sobre os efeitos biológicos e terapêuticos do ultrassom, a fim de identificar o real papel desse recurso no tratamento da tendinite calcária do ombro. Materiais e métodos: Para sua elaboração, foi feita uma busca bibliográfica em bases de dados eletrônicas e uma pesquisa manual. Resultados: Dentre os estudos selecionados, dois demonstraram redução da dor e do tamanho da calcificação e dois não apresentaram resultados positivos. Discussão: Os benefícios promovidos pelo ultrassom são dependentes dos parâmetros utilizados. Variáveis como o tamanho da área a ser tratada, diferenças teciduais, duração da aplicação e o objetivo da conduta terapêutica também devem ser considerados.

    Full Text Available Este trabalho procurou avaliar a eficiência de tratamento floculante com sulfato de alumínio ou cloreto férrico para o efluente bruto neutralizado de uma indústria de celulose e papel. A filtração do efluente, removendo fibras, finos, macromoléculas e flocos naturais, permitiu expressivas reduções da cor aparente, cor real e DQO do mesmo. Enquanto o sulfato de alumínio mostrou excelentes resultados, o cloreto férrico não teve bom desempenho. Deve-se otimizar as concentrações, as formas de agitação e a decantação dos flocos. Para as amostras testadas, na primeira seqüência de testes, concentrações com cerca de 2500 ppm de sulfato de alumínio (com 14 moléculas de água de hidratação mostraram ótimos resultados para redução de cor aparente, cor real, DQO e cloretos. Conforme o previsto, na segunda seqüência de testes as concentrações de [Al2(SO43 . 14 H2O] diminuíram para todos os índices físico-químicos testados. A melhor concentração para pH, cor aparente e cor real foi de 1000 ppm filtrado, enquanto que para cloretos foi de 2000 ppm não filtrado, com o tempo de agitação de 1 minuto com alta velocidade e 15 minutos à baixa velocidade, com exceção da cor real que foi de 10 minutos à baixa velocidade. Como recomendação, sugere-se avaliar uma etapa seqüencial de filtração após clarifloculação/decantação. Com isso, o desempenho de um tratamento físico-químico de efluentes desse tipo será eficiente, apesar do custo envolvido na aquisição do insumo sulfato de alumínio.

    Full Text Available A cessação tabágica é uma das melhores formas de melhorar o prognóstico dos doentes com DPOC. Baseados na evidência actualmente disponível, todos os profissionais de saúde devem ter um papel proactivo e contínuo na motivação para parar e no tratamento para a cessação de todos os fumadores. O tratamento deve incluir farmacoterapia combinada com suporte comportamental e deve integrar o seguimento da doença respiratória crónica como recomendado no Plano Nacional de Prevenção e Controlo da DPOC. Os pneumologistas e os restantes profissionais de saúde devem receber treino que garanta conhecimento, atitudes e capacidades necessários para fornecer estas intervenções ou para referenciar a especialistas na área. No futuro próximo, unidades especializadas em tabagismo deverão fornecer assistência especializada, formação, investigação, divulgação e medidas de controlo na área de saúde de influência (hospital e cuidados de saúde primários.Smoking cessation is one of the most important ways of improving the prognosis of COPD patients. Based on currently available evidence professional health workers should take a proactive and continuous role with smokers, motivating them to stop smoking and providing treatment to aid smoking cessation. The treatment should include pharmacotherapy in addition to behavioural support and should be part of management of the patient’s chronic respiratory condition, as the COPD National Prevention and Treatment Programme recommends. Respiratory physicians and other professional health workers should receive training to ensure they have the necessary knowledge, attitude and skills to undertake these initiatives or to refer the smokers to a suitable qualified specialist. In the near future specialised smoking units should provide specific support, promote training, improve research and awareness and establish tobacco control measures in hospitals and primary health care centres.

  12. Cirurgias conservadoras do baço para tratamento da esplenomegalia por mielofibrose

    Full Text Available A mielofibrose idiopática é uma doença mieloproliferativa crônica, que pode evoluir com hepatoesplenomegalia, também denominada metaplasia, e acometer vários órgãos. Ocasionalmente, o baço alcança proporções gigantescas e precisa ser retirado. Entretanto, esse procedimento é seguido de elevada morbidade e mortalidade. As esplenectomias parciais, que preservam o pedículo esplênico, foram propostas para reduzir complicações pós-operatórias. Após melhora transitória do quadro clínico, surge a recorrência da esplenomegalia e da sintomatologia. A presente comunicação relata duas alternativas para tratamento de esplenomegalia: a esplenectomia subtotal, com preservação do pólo esplênico superior suprido apenas pelos vasos esplenogástricos, e a esplenectomia total, com auto-implantes de tecido esplênico. Realizamos a esplenectomia subtotal em cinco pacientes. O acompanhamento por até dez anos e a melhora clínica dos doentes sugerem que essa operação deva ser considerada para o tratamento de baços gigantes devido à esplenomegalia decorrente de mielofibrose. Um outro paciente foi submetido a esplenectomia total e auto-implante esplênico no omento maior. No seguimento de três anos deste último paciente, não foram registradas complicações relacionadas ao remanescente esplênico. Entretanto, o paciente necessitou de controle hematológico intensivo por causa da gravidade de sua doença de base. Concluindo, se for indicada operação para complementar a terapêutica hematológica da esplenomegalia, deve-se realizar um procedimento conservador do baço. A esplenectomia subtotal ou a esplenectomia total com auto-implantes de tecido esplênico são duas boas escolhas em tais situações.

    Full Text Available Objetivo: Realizar uma revisão sistemática para avaliar e analisar a evidencia científica disponível em terapias para a onicofagia em crianças. Material e métodos: A literatura foi analisada a partir de Medline, Pubmed, ovid, EBSCO, ISI, Cochrane Library, Lylacs, Scielo, Scirus e Internet, publicada desde março de 1985 até 2008. Foram analisados estudos de intervenção ou comparativos, ensaios clínicos, meta-análise ou estudos multicêntricos que incluíram todas as terapias disponíveis para resolver a Onicofagia em crianças de género feminino e masculino. As crianças incluídas nos estudos deviam apresentar ausência de outro tipo de hábitos e/ ou alterações neurológicas. Os estudos incluídos precisavam ter feito um diagnóstico inicial de Onicofagia através da anamnese e técnicas auxiliares para diagnóstico. Resultados: Dos 92 estudos revisados, só um cumpriu os critérios de qualidade. Os estudos selecionados suportam as técnicas psicológicas para o tratamento da Onicofagia, mas não o uso de aparelhos intra-orais ou farmacoterapia em crianças. Conclusão: Muito poucos estudos acerca da terapia para a Onicofagia cumprem os critérios de qualidade requeridos para a prática baseada em evidência. Embora o estudo selecionado cumprisse com os critérios de qualidade, não é suficiente para afirmar que existe adequada evidência para o tratamento da Onicofagia em crianças, pelo mencionado são requeridos futuros estudos que comparem os diferentes tipos de terapia.

    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 energy system&apos;s transformation away from fossil and therefore finite resources and ecological harmful use towards renewable energy sources and sustainable forms of usage proceeds. But even after 35 years, the German energy transition has yet not reached its ambitious goals. Moreover, in the recent years the progress has stagnated in certain areas. This is due to the fact that one of the central challenges of the energy system&apos;s changeover to an sole use renewable energy (RE) have not yet mastered: the reliable and stable delivery of RE for all energy dependent sectors starting form electricity via heat to mobility in the face of fluctuating energy sources like sun and wind. Bioenergy with its flexible use of innovative technologies and smart integration in the overall system is therefore vital to grant stability of energy supply. Furthermore, bioenergy can recourse on sustainable resources and may become therefore the backbone of the future bioeconomy. For this purpose an integrative approach is necessary that aligns the aforementioned building blocks in a cohesive whole: the Smart Bioenergy concept - that will be presented here with its elements but also open questions and challenges.
