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.

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 ''why now'' question constitutes the cosmological ''coincidence problem''. According to the standard model the equality ρ{sub de} = ρ{sub dm} took place ''recently'' at a redshift z ∼ 0.55. The meaning of ''recently'' is, however, parameter dependent. In terms of the cosmic time the situation looks different. We discuss several aspects of the ''coincidence problem'', also in its relation to the cosmological constant problem, to issues of structure formation and to cosmic age considerations. (orig.)

Two personal cases of ''de novo'' 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 ''de novo'' 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 ''de novo'' aneurysms, and a 10% rate of multiple aneurysms. These data are compared with those of the group of reported spontaneous ''de novo'' aneurysms after SAH or previous aneurysm clipping. We agree that the frequency of ''de novo'' 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 ''de novo'' 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 ''de novo'' aneurysm formation. (orig.)

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.

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.

Esses tratamentos foram feitos tanto isoladamente quanto em conjunto e, também, associados à aplicação de inseticida a ultrabaixo volume. Os índices prediais, levantados um mês depois de terminado o trabalho, mostraram que o tratamento focal dispensa qualquer medida auxiliar. O tratamento perifocal mostrou-se inócuo e incapaz de impedir o aparecimento de larvas de Aëdes aegypti e de outros insetos, em pneus pintados, na face externa, com Sumition e com Malation.In four districts of the city of Rio dc Janeiro focal treatment essays with granulated Abate at 1 ppm and perifocal treatment essays with wettable powder of Sumithion at 2,5% were performed. These were made either alone or in combination as well as associated to insecticides applied at ultra low volume. The premise indices obtained one month after the treatments indicates that the focal treatment alone is effective, no other addicional methods being necessary. The perifocal treatment is not effective and did not prevent the development of Aedes aegypti larvae and other insects in tires which had their external surface painted with Sumithion and Malathion.

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 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.

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.)

Comparison of PCDD/Fs levels and profiles in leachates from &apos;'new'&apos; and &apos;'old'&apos; municipal landfills

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.

The &apos;Hot&apos; Electrostatic Precipitator (ESP) equipped with COROMAX pulse system is a very attractive solution for dedusting of the &apos;Hot&apos; exhausted gases from the cement kilns especially on cement plants, where good quality of water is not available on the site. Furthermore, the Electrostatic Precipitator is still the preferred solution in the cement plants for dedusting the cement kiln. It is favored because of its high degree of reliability, its low power consumption, and its low maintenance cost. (author)

Control of carbon emissions to the atmosphere is the environmental issue of this decade - perhaps of this entire generation. Its importance has been equated to the survival of the planet. It may all come down to the novel legal concept that sounds like second-grade math: &apos;'additionality.'&apos; However, it is the &apos;'new'&apos; math. (author)

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.

A dinuclear Eu(III) complex Eu{sub 2}(btbt){sub 3}.4H{sub 2}O.CH{sub 3}CH{sub 2}OH.N(CH{sub 2}CH{sub 3}){sub 3} was synthesized, where H{sub 2}(btbt) was 4,4&apos;-bis (4&apos;&apos;,4&apos;&apos;,4&apos;&apos;,-trifluoro-1&apos;&apos;,3&apos;&apos;-dioxobutyl)-o-terphenyl. 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.

Ichihime, a new soybean variety registered as &apos;&apos;Soybean Norin 103&apos;&apos;, 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. &apos;'Ichihime'&apos; 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

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.

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

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

Full Text Available 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.

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

Energy Technology Data Exchange (ETDEWEB)

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

2003-05-09

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

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

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.

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

International Nuclear Information System (INIS)

Kammer, Adrian; Zurmuehle, Damian; Salzmann, Michael; Baumgartner, Raphael; Mignone, Domenico

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.

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.

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

This 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.)

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.

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;. An experimental test of the predicted quantization is suggested.

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.

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 En varios países latinoamericanos, en las últimas tres décadas, se han creado un número significativo de universidades y otras instituciones de educación superior (IES que según los casos se denominan indígenas y/o interculturales. Adicionalmente, han surgido licenciaturas, diplomados y diversos tipos de programas especiales orientados a la inclusión de personas indígenas en universidades y otras IES “convencionales” (aquellas que no han sido creadas para responder a necesidades, demandas o propuestas de comunidades de pueblos indígenas o afrodescendientes.. Algunas de estas modalidades educativas han sido impulsadas por organizaciones y/o dirigentes indígenas, otras por universidades y otras IES “convencionales”, otras mediante alianzas entre estos tipos de instituciones y organizaciones indígenas, y otras por iniciativas de los Estados. En Argentina estos procesos son relativamente más recientes que en varios otros países de la región. Este artículo presenta un panorama de los tipos de experiencias que vienen desarrollándose en varios países latinoamericanos, señala sus principales logros y desafíos, y propone algunos aprendizajes potencialmente útiles para las experiencias que vienen desarrollándose en Argentina.

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

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.)

Em ambos os casos houve normalização do hemograma em dois meses. Na associação ascaridíase/ancilostomíase também são possíveis dois tipos de comportamento da eosinofilia após tratamento eficaz: ou vai diminuindo a hipereosinofilia, logo em seguida à expulsão dos parasitos, ou há no primeiro mês um aumento da hipereosinofilia (geralmente mais acentuado na primeira semana que se segue ao tratamento, para diminuir após o fim do primeiro mês progressivamente até desaparecer. Na estrongiloidíase e na associação ascaridíase/estrongiloidíase há diminuição constante da hipereosinofilia logo após o tratamento e o hemograma se normaliza em cerca de dois meses. Na trieuríase, a hipereosinofilia, aliás já discreta, diminui pouco com o tratamento. Na ancilostomíase e na associação ancilostomíase/trieuríase a hipereosinofilia ou desce após o tratamento gradativo e lentamente, ou primeiro há uma exaltação temporária nas primeiras três semanas após a terapêutica, para diminuir em seguida. Na associação ancilostomíase/estrongiloidíase também se encontram esses dois tipos de comportamento da hipereosinofilia verminótica, mas a exacerbação da hipereosinofilia, que ocorre na metade dos casos, só dura duas semanas; a regressão eosinofílica ocorre dois meses após o tratamento. Nas tri e tetraeparasitoses a involução pós-terapêutica da hipereosinofilia é irregular e a normalização das taxas sanguíneas de eosinófilos é sempre arrastada, principalmente nas associações ascaridíase/estrongiloidíase/ancilostomíase e

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.

In 1991, a photovoltaic pumping station was commissioned in the natural reserve &apos;&apos;Schwenninger Moos&apos;&apos; in the southern Black Forest. The pumping station was dismantled when the land was used for the 2010 Baden-Wuerttemberg &apos;Landesgartenschau&apos; (garden festival). After 18 years of operation, the plant provided valuable information on the long-term performance of monocrystalline solar modules, so the author made detailed measurements and evaluations just before the plant was dismantled, in an attempt to find out about its long-term performance and cost efficiency. The results are presented here. (orig.)

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.

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.

1983-12-01

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 &apos;&apos;reversed ventilation/perfusion mismatch.&apos;&apos;

&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

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

We 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.

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

Energy Technology Data Exchange (ETDEWEB)

Shahram, Chubin

2008-07-01

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

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.

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

International Nuclear Information System (INIS)

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.

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. This cancer occurs due to mutation of the KIT gene resulting in constitutive activation of KIT protein. The primary treatment is surgical and consists of complete resection. However, some groups of patients at high risk of recurrence even after surgery with complete resection (R0, indicate differences in biological behavior.

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.

Development and utilization of a mechanical barrier for large-calibre cavern necks. The &apos;&apos;Spider Plug&apos;&apos;; Entwicklung und Einsatz einer mechanischen Absperrung fuer grosskalibrige Kavernenhaelse. Der &apos;&apos;Spider Plug&apos;&apos;

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.

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.

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

International Nuclear Information System (INIS)

Escadafal, R.; Huete, A.

1991-01-01

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

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.) [German] Seit der Einfuehrung ionisierender Strahlen als ein Mittel zur Behandlung und Diagnose beim Menschen haben Wissenschaftler versucht, ihre Nebenwirkungen und potenziellen Risiken fuer die Gesundheit einzuschaetzen. Es gibt nun ausreichende Evidenz fuer das grundsaetzliche Vorliegen einer direkten Beziehung zwischen hoeheren Dosen und Nebenwirkungsrisiken. Die meisten Unsicherheiten liegen auf dem Gebiet der Niedrigdosisforschung v. a. im Hinblick auf das Risiko der Induktion von Krebs. Niedrigdosiseffekte sind ueblicherweise von Bedeutung in der diagnostischen Medizin, waehrend Hochdosisbestrahlungseffekte

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

Design Concept of a Seal-off Type 14 MeV Neutron Generator of 10&apos;&apos;1&apos;&apos;1n/s Range

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.

Em uma segunda etapa, quatro tratamentos foram selecionados (fécula de mandioca, 1-MCP, termoterapia e etanol+cloro e avaliados em associação de dois, aplicados de forma sequencial, durante oito dias de armazenamento dos frutos a 25ºC. Os tratamentos 1-MCP e fécula foram os mais eficazes em manter a qualidade físico-química das goiabas ‘Pedro Sato’, retardando a perda de massa, a mudança de coloração da casca e contribuindo para a retenção da firmeza. Constatou-se maior redução de frutos com podridão nos tratamentos com termoterapia, fécula de mandioca e 1-MCP. As associações de tratamento com 1-MCP/fécula de mandioca e termoterapia/fécula foram os tratamentos mais eficazes em manter a qualidade das goiabas ‘Pedro Sato’, retardando a perda de massa, a mudança de coloração da casca e a redução da firmeza. As associações de tratamento reduziram a ocorrência de podridões, com destaque para os tratamentos com etanol+cloro/termoterapia e termoterapia/fécula, que foram mais eficientes até o quarto dia de armazenamento. Observou-se correlação entre a incidência de podridões e os parâmetros cor da casca e firmeza da polpa para a maioria das associações de tratamentos. De maneira geral, recomenda-se o tratamento com termoterapia/fécula para goiabas armazenadas a 22-25ºC, como forma de manutenção da qualidade físico-química e atrasando em, pelo menos, dois dias os sintomas de podridões.

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

After having recalled the legal context concerning the appointment and training of a radiation protection expert (PCR for &apos;personne competente en radioprotection&apos;), the author outlines that the PCR&apos;s role has notably evolved: his function is now of primary importance in the company and his activity does not correspond to the legal framework any longer. Moreover, with the application of a European directive, some small establishments possessing ionizing radiation sources are disadvantaged, and the PCR is now facing an increasing number of missions and tasks. The author gives a list of them and assesses a needed time of 146 days per year: this means PCRs cannot have an other activity within their company

The observation of a bubble of gas at the most non-dependent margin of a lytic bone lesion which has sustained a pathologic fracture implies that the lesion is hollow and can assist the radiologist in making the diagnosis of a unicameral bone cyst. The imaging studies of two patients who sustained pathologic fractures through unicameral bone cysts and exhibited the &apos;&apos;rising bubble&apos;&apos; sign are shown. The sign&apos;s basis, proper utilization, and potential pitfalls are discussed. (orig.)

Full Text Available O Tegretol (5-carbamil-5H-dibenzo-b,L-azepina foi usado no tratamento de 68 pacientes com epilepsia; 54 apresentavam epilepsia temporal (42 com crises psicomotoras e 12 com crises complexas, 11 epilepsia focal de projeção não temporal e 3 epilepsia centrencefálica com crises P.M. 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.

Maintain levels of nicotine but reduce other smoke constituents: a formula for &apos;'less-hazardous'&apos; cigarettes

Robinson, J.C.; Young, J.C.; Rickert, W.S.

1984-09-01

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 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.

Fontes dos dados: revisão bibliográfica através do banco de dados Medline, utilizando os termos: cefaléia, enxaqueca ou migrânea, infância ou adolescência e tratamento, no período de 1966 a 2001, excluindo artigos de revisão e registros de casos. Foram selecionados artigos científicos que relataram estudos sobre a eficácia da terapêutica farmacológica e não farmacológica no tratamento das cefaléias primárias. Síntese dos dados: foram encontrados 104 artigos científicos, sendo selecionados aqueles que relataram estudos do tipo caso-controle, ou droga versus placebo, cegos ou abertos, e que estudassem crianças ou adolescentes. Conclusões: é digna de nota a pobreza de estudos controlados sobre o tema na faixa etária pediátrica, apesar da importância que as cefaléias primárias apresentam na prática clínica. Apenas algumas drogas foram estudadas de forma cientificamente adequada e, mesmo assim, o número de estudos é pequeno. Tanto o tratamento da crise álgica aguda quanto a profilaxia da cefaléia foram abordados.Objective: to perform a bibliographic review about headache treatment in childhood and adolescence. Sources: articles were searched through Medline database using the terms: migraine, or headache, childhood, or adolescence, and treatment, during the period between 1966 and 2001. Review articles and case reports were excluded. Only articles dealing with pharmacological, and non-pharmacological treatment of primary headaches were selected. Summary of the findings: a total of 104 articles were found; only those reporting results of the case-control studies, or drug vs. placebo, either blind, or open, and that included children, or adolescents were selected. Conclusions: only a few controlled studies about the headache treatment were found in the pediatric age group, although primary headaches are

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.)

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.

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.

In June 2014 the Federal Ministry for Economic Affairs and Energy (BMWi) published an expertise prepared by the EWI, GWS and Prognos institutes entitled &apos;&apos;Development of the energy markets - energy reference forecast&apos;&apos;. This study presents probable developments in the energy economy up to the year 2030 (reference forecast) on the assumption of a yet more stringent energy and climate protection policy as well as continuing impediments to its implementation. Complementing the forecast is an outlook up to the year 2050 (scenario of trends). But what do the findings of this expertise say about the future utilization of Germany&apos;s greatest domestic energy resource, namely brown coal? This question is addressed in the following article.

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

Energy Technology Data Exchange (ETDEWEB)

Shepherd, John [nuclear 24, Brighton (United Kingdom)

2015-03-15

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.

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.

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.

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.)

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.

Since 16 years the author, a journalist, pursues the economical and political development of the German power economy. Many facts of this book prove: the impacting consequences as the clear scarcity of 1998 introduced deregulation, which has permitted 8 years long the discrimination of competitors and enabled in this way an exampleless concentration of market might (pt. 1); how supply reliability became worse and power and gas got more and more expensive (pt. 2); the complete insufficient practice of cartel agreements which is exchanged by administrative grid charges respectively &apos;&apos;incentive regulation&apos;&apos; (pt. 3); the relation between management and policy which has become still more distantless than in the epoche of membership books (pt. 4); the development of the German power economy from the beginning in the 19th century to the deregulation incl. the reorganization on the area of the former German Democratic republic.

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.

Accidents, &apos;black swans&apos; and risks

Energy Technology Data Exchange (ETDEWEB)

Luxat, J.C. [McMaster Univ., Dept. of Engineering Physics, Hamilton, Ontario (Canada)

2013-06-15

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.

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

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.

EAGLE: &apos;EAGLE&apos;Is an&apos; Algorithmic Graph Library for Exploration

Energy Technology Data Exchange (ETDEWEB)

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;

ApoE4-specific Misfolded Intermediate Identified by Molecular Dynamics Simulations.

Benfeard Williams

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.

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.

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.

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

Full Text Available O tratamento cirúrgico da siringomielia é, em geral, considerado decepcionante. Vários tipos de drenagem da cavidade siringomiélica não têm fornecido resultados satisfatórios. Gardner, em magnífica série de trabalhos, mostrou que a siringomielia e as várias malformações associadas à hidrocefalia têm fisiopatogenia única. Baseado em sua teoria, Gardner propôs, em 1958, o bloqueio da comunicação entre o IV ventrículo e o canal central da medula, para o tratamento da siringomielia.

The &apos;&apos;ppK{sup -}&apos;&apos; is a well established state in theory and is a candidate for a new kind of hadronic matter formed by antikaons and nucleons. The HADES spectrometer at GSI has probed the existence of such a state by measuring its possible decay products p and Λ. These decay products have been studied specifically in the reaction p+p → p+K{sup +}+Λ at a beam kinetic energy of 3.5 GeV. A partial wave analysis, performed on this final state, helped in describing the event distributions, which is a necessary condition to search for an additional small signal in the statistic. We have found no indication for the production of a kaonic nuclear bound state in our data and have, thus, set an upper limit for its production cross section. Furthermore, did we repeat the analysis of the DISTO collaboration in which a signal like distribution appeared in so-called deviation spectra. We can show that this method is error-prone in terms of the applied selection cuts and is, thus, not reliable in order to make statements about the &apos;&apos;ppK{sup -}&apos;&apos;.

&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.

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}.

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.) [German] Stufenlos wirkende Nockenwellenversteller haben sich an modernen Ottomotoren in den letzten Jahren in der Grossserie etabliert. Mit der neuesten Generation von Nockenwellenverstellern, die nach dem Schwenkmotor-Prinzip aufgebaut sind, lassen sich grosse Verdrehwinkel sehr schnell und betriebssicher verstellen. Der Aufbau dieser Versteller ist einfach, und die Herstellkosten sind gering im Vergleich zur ersten Generation von Verstellern. Bei den Systemen der neuen Generation handelt es sich um mechatronische Systeme, deren Funktion von dem Zusammenspiel und der Abstimmung von hydraulischer Ansteuerung und Motorelektronik abhaengt. Mit dem Begriff &apos;VaneCAM&apos; werden die stufenlos wirkenden Systeme dieser neuen Generation von Hydraulik-Ring aus Nuertingen bezeichnet. (orig.)

&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

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

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

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

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.

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.

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.

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.

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.

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

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.

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.

Einstein-Rosen &apos;bridge&apos; revisited and lightlike thin-shell wormholes

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.

&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).

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.

Differential response of the skin in young and old rats to a combination of X-rays and &apos;wet&apos; or &apos;dry&apos; hyperthermia

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.

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

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

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

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

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

The 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.

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.

Detailed NMR and mass spectrometry studies indicate that the ligand forms 1:2 complexes with lanthanide(III) perchlorates where the aliphatic rings are conformationally constrained whereas 1:1 complexes are formed with lanthanide(III) nitrates where the aliphatic rings are conformationally mobile. An optimized structure of the 1:2 solution complex with Yb(III) was obtained from the relative magnitude of the induced paramagnetic shifts. X-ray crystallographic structures of the ligand and of its 1:1 complex with Y(III) were also obtained. In the absence of a phase-modifier, CyMe 4 -BTTP in 1-octanol showed a maximum distribution coefficient of Am(III) of 0.039 (±20%) and a maximum separation factor of Am(III) over Eu(III) of 12.0 from nitric acid solution. The metal(III) cations are extracted as the 1:1 complex from nitric acid solutions. The generally low distribution coefficients observed compared with the BTBPs arise because the 1:1 complex of CyMe 4 -BTTP is considerably less hydrophobic than the 1:2 complexes formed by the BTBPs. In M(BTTP) 3+ complexes, there is a competition between the nitrate ions and the ligand for the complexation of the metal. (authors)

Full Text Available PURPOSE: To verify the effect of consumption of grape extract isolated or combined with α-tocopherol supplementation on atherosclerosis model with Apo E -/- mice. METHODS: After six weeks of atherogenic diet, Apo E -/- mice were divided into the following groups: Control, Grape, Tocopherol and Grape plus Tocopherol. The treatment progressed for 11 weeks when animals were submitted to euthanasia. RESULTS: All the treatments presented hypocholesterolemic effect with reduction of serum and liver cholesterol levels. This effect was parallel to an increase in the fecal excretion of cholesterol. There was also a higher fecal excretion of saturated fatty acids in groups receiving grape extract or α-tocopherol. All the groups treated presented a tendency to show higher levels of vitamin E. The fatty acid profile showed a tendency for monounsaturated fatty acid preservation after grape extract and α-tocopherol consumption. Morphological analysis revealed a lower degree of evolution of the atherosclerotic plaque of the animals that were fed α-tocopherol combined with grape extract, even when no difference was found in the size of the largest lesion. CONCLUSION: A synergistic effect between the polyphenols and α-tocopherol was observed, resulting in diminished evolution of atherosclerosis and a greater beneficial effect on atherosclerosis than the isolated consumption of antioxidants.OBJETIVO: Verificar o efeito do consumo de extrato de uva isolada ou combinada com a suplementação de α-tocoferol em modelo de aterosclerose, utilizando camundongos Apo E -/-.

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.

Pharmaceutical induction of ApoE secretion by multipotent mesenchymal stromal cells (MSCs

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

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

Energy Technology Data Exchange (ETDEWEB)

Bianchi, Riccardo Maria

2014-03-18

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

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.)

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.

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.

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.)

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

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.

Quantifying the &apos;naturalness&apos; of the curvaton model

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.

Full Text Available Resumo Este trabalho teve como objetivo identificar as representações sociais e os fatores que influenciam a adesão ao tratamento antirretroviral. 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. Abstract This study aims to identify the social representations and the factors that influence in the adherence to antiretroviral treatment. The participants in the study were 154 people who were undergoing antiretroviral treatment, 82 men with an average age of 40 years and three months. The data was obtained through direct interviews and through a scale of adherence to antiretroviral treatment. The textual material in relation to the meaning of the treatment was analyzed by the IRAMUTEQ software. The treatment is represented in two concepts: First, from a normal life maintained by the idea of continuous and regular use of medications shared by people with high adherence to treatment. Second, as something which generates social suffering, and isolation, most characteristic of people with low/inadequate, and

The e-mail utilization rate at mobile communication terminals is increasing at a remarkable rate, as if to grow above the rate of communication by voice. Under the circumstances, a PHS (Personal Handyphone System) terminal &apos;TEGACKY&apos; (type name: PM-T101) has been developed, designed exclusively for use for e-mailing. &apos;TEGACKY&apos; is characterized in that its icons may be activated with pen, that input may be made by handwriting, and that its large screen allows a 48-character message consisting of 4 lines of 12 characters to be displayed at one time despite its compact size. It can also perform communication directly with other terminals or e-mail via center, and is provided with an information service function. &apos;TEGACKY&apos; having such distinguished features has created a new category of terminals which are at once e-mailing tools.

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.).

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

This 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 publication outlines the &apos;medical research&apos; licensing procedure as specified in the amendment of the German Radiation Protection Ordinance of November 1, 2011. The general licensing requirements for the use of radiation have not been changed by the amendment. Three so-called use restrictions (i.e., dose limits of 10 mSv and 20 mSv, age limit of 50 years) have been modified. They will only apply to healthy volunteers in the future. In addition, there are considerable simplifications with respect to applications and licensing procedures of the Federal Office for Radiation Protection (Bundesamt fuer Strahlenschutz, BfS) regarding the use of radiation in the newly introduced &apos;accompanying diagnostics&apos; (&apos;Begleitdiagnostik&apos;) case group. The newly established, independent panel of experts at the German Radiological Society (Deutsche Roentgengesellschaft, DRG) may provide essential support to principal investigators, qualified physicians and sponsors for differentiating between &apos;medical research&apos; and &apos;health care&apos;, the latter not being subject to licensing.

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.

Prospects for neutron star equation of state constraints using &apos;'recycled'&apos; millisecond pulsars

Energy Technology Data Exchange (ETDEWEB)

Bogdanov, Slavko [Columbia University, Columbia Astrophysics Laboratory, New York, NY (United States)

2016-02-15

&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.

Energy and the new class. [Assault of &apos;&apos;new breed&apos;&apos; of American on established institutions

Energy Technology Data Exchange (ETDEWEB)

King, L.

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.

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.

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.

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 role of the &apos;&apos;year without a summer&apos;&apos; (YWAS) in 1816 in shaping the scientific discourse on climatic changes has been investigated in an interdisciplinary project by studying reactions of different knowledge systems to the YWAS as an initially unexplainable event. The analysis of two Swiss newspapers shows that contemporary science did not play a role in perceiving and dealing with the impacts of the YWAS on the population. Since no climate discipline of its own existed, few contemporary scientist, as we would call those men of science today, were ready to take this situation as an opportunity, reinforcing existing ideas in their domain (e.g. botany, geology, astronomy). Nevertheless, the YWAS did have impacts on science. A &apos;'call'&apos; was issued by the Swiss Natural Sciences Society shortly after the event. The work of one of the respondents became influential for the development of the ice age theory. By revealing a general lack of knowledge on climate, the YWAS might have contributed to the construction of meteorological stations at that time. Some contemporary scientists argued that the cold summer in western Europe was caused by huge masses of ice drifting in the North Atlantic. However, there were no theories that could have linked the exceptionally wet weather in Europe with a volcanic eruption on the other side of the globe. Not before the early 20{sup th} century was the YWAS linked to the Tambora eruption of 1815. After almost two centuries, the YWAS has remained a challenge and source of inspiration. (orig.)

&apos;Lifecycle cost&apos; management is a new kind of management. The International Nuclear Fusion Energy Program was managing by &apos;lifecycle cost&apos; method. The cost and other factors associated with cost were under control by the method. In the future, the system engineering method should be focused in engineering management, paying equal attention to both evaluation and management, and strengthening the application of information system in the cost management to effectively improve the management level.

2008-03-15

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

Jevons&apos; paradox

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.

A novel &apos;&apos;3+1&apos;&apos; mixed ligand {sup 99m}Tc complex with N,N-bis(2-mercaptoethyl)-N&apos;N&apos;-diethyl-ethilenediamine as ligand and 1-octanethiol as coligand was prepared and evaluated as potential brain radiopharmaceutical. Preparation at tracer level was accomplished by substitution, using {sup 99m}Tc-glucoheptonate as precursor and a coligand/ligand ratio of 5. Under these conditions the labeling yield was over 80% and a major product with radiochemical purity >80% was isolated by HPLC methods and used for biological evaluation. Chemical characterization at carrier level was developed using the corresponding rhenium and {sup 99g}Tc complexes. Results were consistent with the expected &apos;&apos;3+1&apos;&apos; structure and X-ray diffraction study demonstrated that the complex adopted a distorted trigonal bipyramidal geometry. All sulphur atoms underwent ionization leading to the formation of a neutral compound. Biodistribution in mice demonstrated early brain uptake, fast blood clearance and excretion through hepatobiliary system. Although brain/blood ratio increased significantly with time, this novel {sup 99m}Tc complex did not exhibit ideal properties as brain perfusion radiopharmaceutical since brain uptake was too low.

ISO 3171 production hydrocarbons allocation sampling for challenging &apos;'tie-ins'&apos;with pressures close to RVP breakout

Energy Technology Data Exchange (ETDEWEB)

Jiskoot, Mark

2005-07-01

There are an increasing number of applications where sampling is required for crude oils and condensates at close to vapour breakout in production environments. These are typified where the quality measurement must be extracted/made in the &apos;'oil'&apos; leg of a separator. The exertion of back pressure (pressure loss) on the liquid leg to expand the operating envelope is generally not acceptable due to the effect that this will have on the separator efficiency and this frequently precludes the use of normal metering technologies. These conditions represent some of the hardest for quality determination. In conventional separators, velocities are low to promote separation of the gas and liquids and the therefore the gas pressure within the liquid phase is close to breakout. Frequently there is an envelope of less than 0.5 bar below the operating pressure at which the fluid will start to cavitate. Concurrent with the low velocity is the expectation of some free water that would require mixing to ensure representativity. There are frequently also severe restrictions on space and the piping arrangement in which to achieve a representative off-take. The &apos;'rules'&apos; that are applied to representative sampling are equally applicable to the use of water monitors (water cut, OWD) and to densitometers. An integrated quality measurement system that prevents any impact on the process and also provides the required mixing to allow extraction of a representative off take that can be used for physical samplers as well as process instrumentation such as densitometers, viscometers and water cut monitors can be achieved by careful design. Jiskoot has adapted its CoJetix technology to meet these goals. (author) (tk)

We describe here the &apos;Atomic bremsstrahlung&apos; (AB)-emission of continuous spectrum electromagnetic radiation, which is generated in collisions of particles that have internal deformable structure that includes positively and negatively charged constituents. The deformation of one or both colliding partners induces multiple, mainly dipole, time-dependent electrical moments that become a source of radiation. The history of AB invention is presented and its unusual in comparison to ordinary bremsstrahlung (OB) properties, are discussed. As examples, fast electron atom, non-relativistic and relativistic collisions are considered. Attention is given to ion-atom and atom-atom collisions. Specifics of &apos;elastic&apos; and &apos;inelastic&apos; (i.e. radiation accompanied by destruction of collision partners) AB will be mentioned. Attention will be given to possible manifestation of AB in nature and in some exotic systems, for instance scattering of electrons upon muonic hydrogen. Some cooperative effects connected to AB will be considered. New classical schemes similar to AB will be presented.

Fouchard, D.; Ruggier, L.; Taylor, B.J.

1987-05-01

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.

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.

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.

Given real personal embarrassment, the Chernobyl accident indeed has had an impact on the vital consciousness, and this effect has been developing in two phases, an initial phase, and a subsequent phase characterised by mental digestion. In the initial, post-accident phase, the typical &apos;Chernobyl feeling&apos; is frequently predominant. If this feeling later is weakened or diluted by a back-to-normal attitude, no bearing effects on vital consciousness or identity feeling can be observed, but a general feeling of pessimism and resignment remains. If, however, &apos;normalisation&apos; did not set in until the first interview in this study, personal identity is found to be undergoing a change. A more conscious apprehension of life can be observed, a change in life style up to political commitment, or also leading to a determined turn to short-term, private compensating activities, (last-minute panic).

of several months, even though patients are already free of symptoms. In total, blood patch therapy is a safe and technically relative simple method with a high success rate. Therefore, it represents the therapy of choice in patients with spontaneous cerebrospinal fluid leakage as well as in cases of post-lumbar puncture syndrome refractory to conservative therapy. (orig.) [German] In den meisten Faellen ist ein Liquorverlustsyndrom iatrogen durch Lumbalpunktionen, Periduralanaesthesien oder operative Eingriffe an der Wirbelsaeule bedingt. Durch verbesserte diagnostische Moeglichkeiten werden jedoch auch spontane Liquorverlustsyndrome mit zunehmender Haeufigkeit diagnostiziert, deren Ursache oft nicht eindeutig zu klaeren ist. Zur radiologischen Diagnosesicherung und zur Lokalisierung des Liquorlecks stehen mit der Postmyelo-CT, der {sup 111}Indium-Radioisotopenzisternographie und der (Myelo-)MRT mehrere Verfahren mit unterschiedlichen Sensitivitaeten zur Verfuegung. Nach unserer eigenen Erfahrung ist eine primaer nativdiagnostische MRT mit fettsaturierten T2-Sequenzen in vielen Faellen bereits diagnostisch ausreichend, um das Liquorleck und seine Lokalisation zu sichern. In den uebrigen Faellen ist die Durchfuehrung einer ergaenzenden Postmyelo-CT oder alternativ einer Myelo-MRT empfehlenswert. Bei manchen Patienten mit spontanem Liquorverlustsyndrom finden sich dabei mehrere Liquorlecks auf unterschiedlichen Hoehen. Leitsymptom ist in den meisten Faellen ein lageabhaengiger orthostatischer Kopfschmerz. Waehrend das postpunktionelle Syndrom unter Bettruhe und medikamentoeser Therapie oft selbstlimitierend ist, bedarf es beim spontanen Liquorverlustsyndrom meist einer Blood-patch-Therapie.

&apos;'Spin-dependent'&apos; μ → e conversion on light nuclei

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. Then we explore the prospects for distinguishing coefficients or models by using different targets, both in an EFT perspective, where a geometric representation of different targets as vectors in coefficient space is introduced, and also in three leptoquark models. It is found that comparing the rate on isotopes with and without spin could allow one to detect spin-dependent coefficients that are at least a factor of few larger than the spin-independent ones. Distinguishing among the axial, tensor and pseudoscalar operators that induce the SD rate would require calculating the nuclear matrix elements for the second two. Comparing the SD rate on nuclei with an odd proton vs. odd neutron could allow one to distinguish operators involving u quarks from those involving d quarks; this is interesting because the distinction is difficult to make for SI operators.

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. Then we explore the prospects for distinguishing coefficients or models by using different targets, both in an EFT perspective, where a geometric representation of different targets as vectors in coefficient space is introduced, and also in three leptoquark models. It is found that comparing the rate on isotopes with and without spin could allow one to detect spin-dependent coefficients that are at least a factor of few larger than the spin-independent ones. Distinguishing among the axial, tensor and pseudoscalar operators that induce the SD rate would require calculating the nuclear matrix elements for the second two. Comparing the SD rate on nuclei with an odd proton vs. odd neutron could allow one to distinguish operators involving u quarks from those involving d quarks; this is interesting because the distinction is difficult to make for SI operators.

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

The main purpose of this work is the development of a computing tool for the exergetic analysis of a cement baking unit belonging to the &apos;Societe Tuniso-Algerienne de Ciment Blanc (SOTACIB)&apos;. We chose to study this unit in particular because it accounts for about 30 to 60 % of the total cement production costs. The developed program, called &apos;CIMEX&apos;, its capable of computing mass and energy balances and estimating the exergetic losses and efficiencies associated with the main operations of the studied unit. The results of the exergetic analysis were used to study the economic impact of recovering some of the energetic reserves in order to improve the efficiency of the baking unit which will make the subject of another article.

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)

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

The 11th &apos;World Solar Challenge&apos; started in mid-October 2011. This a race of solar cars across Australia is the most spectacular of its kind, but it is hardly a test for solar cars of the future as the regulations for racing cars are far from those for everyday electric-powered solar vehicles. A normal-looking car like the &apos;Solarworld GT&apos; developed at Bochum university therefore has no real chance of winning, however proud its designers may be.

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.

The trial took place in July 1987, and it was a speedy trial of three weeks until the ruling from indictment reading. The court was virtually &apos;closed.&apos; The accused were the following 6 persons: Director of Chernobyl NPP, power plant chief engineer, power plant deputy chief engineer, second reactor work center chief, Chernobyl NPP National Nuclear Energy Supervisory Board inspector, and power plant night shift chief. Court records or court documents have not officially published as of March 2013. These court records have been reconstructed from the memos of Nikolay Karpan (Chernobyl NPP nuclear safety ex-deputy chief engineer), who recorded them at a time when he appeared in the court as a witness, and when he attended the court for hearing. The impressions of the translator are as follows. (1) The first purpose of the trial was to promptly punish responsible persons, and to put an end to the accident. (2) Emphasis was not placed on the investigation of the accident cause or accident background. (3) As Mr. Karpan pointed out, this trial gave impression that it was &apos;farce&apos; according to certain &apos;scenario&apos; or &apos;fixed game&apos; that was held in order to conclude that the accident was caused by the sins of accused persons. As for the defects of the nuclear reactor as the defendants pointed out, they were dismissed as &apos;separate issues to be addressed,&apos; and eliminated from judgment contents. (4) All the accused denied the indictment contents (asserting the inadequacy of the reactor itself, deficiencies of regulations and documentations, and deficit of authority). However, they admitted the moral responsibility for being unable to prevent the accident. All the defendants received actual prison term of 2 to 10 years with correctional labor. (A.O.)

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.

The Fifth International Symposium &apos;&apos;Atomic Cluster Collisions&apos;&apos; (ISACC 2011) will take place in July 21-25, 2011 in Berlin, Germany. 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

The International Education Training Centre (IETC) at Moscow Federal State Unitary Enterprise (FSUE) &apos;Radon&apos;, in co-operation with the International Atomic Energy Agency (IAEA), has developed expertise and provided training to waste management personnel for the last 15 years. Since 1997, the educational system of the enterprise with the support of the IAEA has acquired an international character: more than 470 experts from 35 countries - IAEA Member States completed the professional development. Training is conducted at various thematic courses or fellowships for individual programs and seminars on IAEA technical projects. In June 2008 a direct agreement (Practical Arrangements) has been signed between FSUE &apos;Radon&apos; and the IAEA on cooperation in the field of development of new technologies, expert&apos;s advice to IAEA Member States, and, in particular, the training of personnel in the field of radioactive waste management (RWM), which opens up new perspectives for fruitful cooperation of industry professionals. A similar agreement - Practical Arrangements - has been signed between Lomonosov&apos;s MSU and the IAEA in 2012. In October 2012 a new IAEA two-weeks training course started at Lomonosov&apos;s MSU and FSUE &apos;Radon&apos; in the framework of the Practical Agreements signed. Pre-disposal management of waste was the main topic of the courses. The paper summarizes the current experience of the FSUE &apos;Radon&apos; in the organization and implementation of the IAEA sponsored training and others events and outlines some of strategic educational elements, which IETC will continue to pursue in the coming years.

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. In the last part we will briefly describe the broadening of VPU uses

Targeted In Situ Gene Correction of Dysfunctional APOE Alleles to Produce Atheroprotective Plasma ApoE3 Protein

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available Cardiovascular disease is the leading worldwide cause of death. Apolipoprotein E (ApoE is a 34-kDa circulating glycoprotein, secreted by the liver and macrophages with pleiotropic antiatherogenic functions and hence a candidate to treat hypercholesterolaemia and atherosclerosis. Here, we describe atheroprotective properties of ApoE, though also potential proatherogenic actions, and the prevalence of dysfunctional isoforms, outline conventional gene transfer strategies, and then focus on gene correction therapeutics that can repair defective APOE alleles. In particular, we discuss the possibility and potential benefit of applying in combination two technical advances to repair aberrant APOE genes: (i an engineered endonuclease to introduce a double-strand break (DSB in exon 4, which contains the common, but dysfunctional, ε2 and ε4 alleles; (ii an efficient and selectable template for homologous recombination (HR repair, namely, an adeno-associated viral (AAV vector, which harbours wild-type APOE sequence. This technology is applicable ex vivo, for example to target haematopoietic or induced pluripotent stem cells, and also for in vivo hepatic gene targeting. It is to be hoped that such emerging technology will eventually translate to patient therapy to reduce CVD risk.

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

International Nuclear Information System (INIS)

Owen, James E.

2014-01-01

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

We exactly calculate the double and simple inclusive transverse momentum (kt) distributions and the 2-particle momentum correlations inside high energy hadronic jets at the Modified Leading Logarithmic Approximation (MLLA) of Quantum Chromodynamics. We first obtain the exact solution of the evolution equations at &apos;small x&apos;, which we calculate at the so called &apos;limiting spectrum&apos;. We then generalize this approximation by performing the steepest descent evaluation. Our predictions are in good agreement with data from Tevatron and improve those which have been obtained in the past. The comparison with forthcoming data (Tevatron, LHC) will further test the hypothesis of Local Hadron Parton Duality, and the eventual need to incorporate next-MLLA corrections. (authors)

Purpose: To evaluate color-Doppler features predictive of focal Hashimoto&apos;s thyroiditis. Materials and methods: A total of 521 patients with 561 thyroid nodules that underwent surgeries or gun biopsies were included in this study. These nodules were divided into three groups: focal Hashimoto&apos;s thyroiditis (104 nodules in 101 patients), benignity other than focal Hashimoto&apos;s thyroiditis (73 nodules in 70 patients), and malignancy (358 nodules in 350 patients). On color Doppler sonography, four vascularity types were determined as: hypovascularity, marked internal flow, marked peripheral flow and focal thyroid inferno. The {chi}{sup 2} test was performed to seek the potential vascularity type with the predictive ability of certain thyroid pathology. Furthermore, the gray-scale features of each nodule were also studied. Results: The vascularity type I (hypovascularity) was more often seen in focal Hashimoto&apos;s thyroiditis than other benignity and malignancy (46% vs. 20.5% and 19%). While the type II (marked internal flow) showed the opposite tendency (26.9% [focal Hashimoto&apos;s thyroiditis] vs. 45.2% [other benignity] and 52.8% [malignancy]). However, type III (marked peripheral flow) was unable to predict any thyroid pathology. Importantly, type IV (focal thyroid inferno) was exclusive to focal Hashimoto&apos;s thyroiditis. All 8 type IV nodules appeared to be solid, hypoechoic, and well-defined. Using &apos;focal thyroid inferno&apos; as an indicator of FHT, the diagnostic sensitivity and specificity were 7.7% and 100% respectively. Conclusions: The vascularity type of &apos;focal thyroid inferno&apos; is specific for focal Hashimoto thyroiditis. Recognition of this particular feature may avoid unnecessary interventional procedures for some solid hypoechoic thyroid nodules suspicious of malignancy.

Full Text Available O tratamento do zumbido é, ainda nos dias de hoje, um grande desafio para os otorrinolaringologistas. Várias lacunas persistem em sua fisiopatologia, tendo como resultado vários tipos de tratamento, com resultados muito irregulares. O acamprosato é uma droga utilizada no tratamento do alcoolismo, devido à sua ação reguladora da transmissão glutamatérgica e GABA-érgica, nunca tendo sido empregado no tratamento do zumbido. OBJETIVO: Avaliar a segurança e eficácia do uso do acamprosato, no tratamento do zumbido de causa neurossensorial. FORMA DE ESTUDO: ensaio clinico randomizado. MATERIAL E MÉTODO: 50 pacientes com zumbido de causa neurossensorial foram divididos em 2 grupos, 25 recebendo acamprosato e 25 placebo por 3 meses, em um estudo prospectivo duplo-cego, sendo analisados os efeitos terapêuticos e efeitos colaterais, de acordo com escala (nota de 1 a 10, atribuída pelo próprio paciente. RESULTADOS: Foi observado algum grau de melhora sintomatológica em 86,9% dos pacientes, sendo que em 47,8% dos casos observamos melhora superior a 50%, dados estatisticamente significativos em relação ao placebo. A incidência de efeitos colaterais encontrada foi baixa (12% e de intensidade leve, com boa tolerabilidade geral. CONCLUSÃO: O acamprosato, medicação utilizada no tratamento do alcoolismo, é eficaz e seguro para o tratamento do zumbido de causa neurossensorial, com percentual de melhora superior à maioria das medicações utilizadas para o tratamento do zumbido, constituindo uma excelente alternativa terapêutica.Nowadays, the treatment of tinnitus is still a great challenge for the otolaryngologists. Many facts remain unknown in its pathophysiology, leading to many different therapies, with irregular results. Acamprosate is a drug used in alcoholism treatment, due to its regulating effects in glutamatergic and GABA neurotransmission, and has never been used before in the treatment of tinnitus AIM: To evaluate efficacy and

Full Text Available Introdução: O binômio dieta e nutrição tem relação com causas e consequências do câncer. O estado nutricional é afetado diretamente tanto pelo tumor, quanto pelo tratamento administrado, exigindo manejo especial. Quando há depleção do estado nutricional, associa-se diminuição da função imune, o que favorece o avanço da doença. Para isso a imunonutrição poderia colaborar com a diminuição da taxa de infecções e do tempo de hospitalização no tratamento de pacientes com câncer. Objetivo: Revisar o papel da imunonutrição na melhora da resposta ao tratamento do câncer. Materiais e Métodos: Realizou-se estudo exploratório do tipo revisão bibliográfica a partir das bases de dados PubMed e LILACS, datados a partir de 1998, com os termos de indexação: imunomoduladores, câncer, terapia nutricional. Foram incluídas obras bibliográficas do tema em questão e outros artigos de relevância. Resultados: Foi realizada a revisão com sete estudos. Foram incluídos nesta revisão cinco capítulos de obras bibliográficas e outros três artigos de relevância do assunto. Os resultados foram organizados em uma categoria e três temas: imunonutrição no tratamento ao câncer, abrangendo conceito e características, tempo de administração de dietas imunomoduladoras e as neoplasias nas quais imunonutrição está mais envolvida. Conclusões: Poucas pesquisas com resultados significativos são encontradas quando comparadas a dietas-padrão, não sendo possível afirmar com segurança sobre os benefícios da imunonutrição no tratamento dos pacientes oncológicos em relação ao tempo de administração de fórmulas enriquecidas com esses imunomoduladores. Contudo, os benefícios relacionados a diminuição da taxa de infecções e ao tempo de hospitalização estão associados ao tipo de tratamento cirúrgico do câncer

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

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

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

Do you recall the fable of the boy who cried wolf? I was reminded of this following the latest call by Germany&apos;s Federal Environment Minister, Barbara Hendricks, for Belgium to take two of its nuclear reactors off the grid, citing &apos;'questions'&apos; about the units&apos; safety. 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.

In 2005, the European Union released the EuP Directive focusing on ecodesign requirements for energy-using products (2005/32/EC: EU Parliament and Council of the EU 2005). This directive, also called Ecodesign Directive, is a framework directive establishing a structure in which so-called implementing measures define specific requirements for placing products on the market and/or putting them into service within the internal European market. These requirements can be environmental performance standards (e.g. minimum energy efficiency or emission standards) and labelling or information requirements. Some existing European directives are already declared as being implementing measures of the Ecodesign Directive. Additionally, new implementing measures have been and will further be developed. Product-specific preparatory studies on behalf of the European Commission provide the basis for this. The preparatory studies for boilers (Lot 1) and water heaters (Lot 2) have been conducted from February 2006 to October 2007 by Van Holsteijn en Kemna (VHK). Based on the preparatory studies, the EU Commission has released several working documents (WD) on possible ecodesign requirements for boilers and water heaters at the beginning of 2008. Following these documents, boilers and water heaters comprise gas-fired, oil-fired and electric central heating (CH) (combi-) boilers / dedicated water heaters in combination with capturing solar thermal energy or ambient heat1. The requirements contain basically energy labelling measures, minimum efficiency performance standards and limits on NOx emissions. An &apos;&apos;Ecoboiler Model&apos;&apos; resp. an &apos;&apos;Eco Hot Water Model&apos;&apos; has been elaborated within the preparatory studies. These models are a crucial part of the requirements and allow for calculation of the efficiencies of boilers and water heaters. Since the models have a high degree of complexity, the Federal Environment Agency (UBA) has asked Wuppertal

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

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.

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

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

To observe monocyte (Mo) development in wild type C57BL/6 mice and apoE gene knockout (apoE(-/-)) mice, and to evaluate the immuno-regulatory effect of Huanglian Jiedu Decoction (HJD) on peripheral Mo development in apoE(-/-) mice. Four, 8, 12, and 16 weeks old female C57BL/6 mice were set up as control groups of different ages, while 4, 8, 12, and 16 weeks old female apoE(-/-) mice were set up as hyperlipidemia groups of different ages. Four-week old female C57BL/6 mice were recruited as a blank group. Four-week old female apoE(-/-) mice were randomly divided into the control group, the Western medicine group, and the Chinese medicine group by paired comparison, 5 in each group. Equivalent clinical dose was administered to mice according to body weight. Mice in the Western medicine group were administered with Atrovastatin at the daily dose of 10 mg/kg by gastrogavage, while those in the Chinese medicine group were administered with HJD at the daily dose of 5 g/kg by gastrogavage. Body weight was detected each week. After 4 weeks blood lipids levels (such as TG, TC, LDL-C, and HDL-C), and the proportions of Mo and Ly6c(hi) were detected. Compared with 4-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05). Levels of TC and TG, and the proportion of Ly6c(hi) subtype increased, but the proportion of Mo de- creased in 8-week-old apoE(-/-) mice (P <0. 05). Levels of TC, TG, and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05). Levels of TC, TG, LDL-C, and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with 8-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05); levels of TC and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05); levels of TC and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with C57BL/6 mice of the same age, TC and TG increased, HDL-C decreased (P < 0.01) in 4-and 8-week-old apoE(-/-) mice (P

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.)

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.

Full Text Available O tratamento das hemorragias subaracnóideas espontâneas é estudado pormenorizadamente. Com poucas exceções, êsses casos são devidos a rotura de um aneurisma intracraniano, situado em 72% dos casos na artéria carótida interna ou em um de seus ramos principais. A incidência e a etiologia dos aneurismas são discutidas. O aneurisma se deve a um imperfeito desenvolvimento das paredes vasculares, associado a uma lesão degenerativa. A sintomatologia está ausente, na grande maioria dos casos, até a rotura do aneurisma, quando o paciente perde a consciência, entra em choque, com sinais de comprometimento dos nervos cranianos ou dos centros superiores. A presença de sangue no líqüido cefalorraquídeo, com aumento da pressão, é achado diagnóstico. O prognóstico dos aneurismas é grave; 40% dos pacientes vêm a falecer com a primeira hemorragia; daqueles que resistem ao primeiro acidente, 30% virão a falecer no segundo, terceiro ou quarto episódios dentro de um período de 10 anos. O tratamento da fase aguda é conservador, com absoluto repouso no leito. Quando as condições o permitam, arteriografias devem ser obtidas para demons- tração do aneurisma. O tratamento cirúrgico deve então ser instituído, a técnica variando de acôrdo com a localização da lesão, condições da circulação colateral, possibilidade de acesso cirúrgico direto, etc. O tratamento indireto deve ser associado ao direto, sempre que possível; far-se-á, portanto, a oclusão de uma ou mais artérias no pescoço com subseqüente isolamento intracraniano do aneurisma. As diferentes técnicas cirúrgicas são discutidas. Nos casos tratados pelo método conservador a mortalidade é de 48% e nos casos tratados pela cirurgia, de 14%. Cinco casos de aneurismas intracranianos são apresentados com a finalidade única de ilustrar os problemas clínicos. Êsses casos demonstram os diferentes tipos de evolução clínica e refletem a gravidade do progn

&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

On the base of the documents from his life and work, i. e. deeds, letters and reports of contemporaries, as well as the published and unpublished essays, books, and articles of Heisenberg - also the later on found, publications or manuscripts mainly coming from the inheritance - resulted this systematic biography of Heisenberg. The author, the last doctoral candidate of Heisenberg relied furthermore on factual and personal knowledges, mainly own remembrances on his doctoral father and his teachers, colleagues, and students. Because of the interest of an authentical biography of the theoretical physicist Heisenberg the presentation of the mathematical approaches and the corresponding derivations could not completely be abandoned. This biography appeals by this both to a scientifically cultivated as a wider in science interested audience and covers the first phase of Heisenberg&apos;s life until his Nobel price 1933.

2014-01-01

This thesis demonstrates the growing importance of deep groundwater research and the increasing demand for the development of suitable single-well test methods. At the forefront of the research on groundwater in the deep underground, radioactive waste disposal in deep geological repositories, CO 2 storage, geothermal energy supply, and aquifer storage and recovery systems (ASR) are on the agenda. The developments of suitable methods for investigating these resources are a main target. Currently available methods show considerable limitations. Accordingly, comprehensive methods for the hydraulic and hydrochemical characterization of deeper aquifers with single-well access are needed. Therefore, the goal of this PhD thesis was to identify, test, and enhance potentially suitable single-well methods for characterization of groundwater flow and solute transport in such settings. For this, several Single-Well Injection-Withdrawal (&apos;'push-pull'&apos;) tracer tests were applied at the Hamasato field site (Horonobe, Japan) in a ∝100 m deep groundwater monitoring well. Aim was to characterize the impact of a dynamic saltwater-freshwater interface on a coastal aquifer. Based on the experiences of the first methodological test, a second field campaign was conducted. This campaign focused on a systematic evaluation of the push-pull tracer test method for the first time at all. The experiments focused on the investigation of the so-called &apos;'chaser'&apos; and its impact on the test results. The chaser is a specific part of many push-pull tracer tests setups. From these experiments, a specific test design for the investigation of the saltwater-freshwater interface in a single-well setting was developed. The application of this design on questions regarding different fluids within the same system, e.g. different mineralized fluids (saltwater-freshwater-interface, ASR) or temperatures (geothermal research), are promising future approaches for this

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.

&apos;Carbon-Money Exchange&apos; to contain global warming and deforestation

This paper builds a basic theory of &apos;Carbon-Money Exchange&apos; in which carbon as currency in nature&apos;s household (ecosystems) and money as currency in humankind&apos;s household (economy) are exchanged just like in a foreign exchange. The simple chemical equation below makes it possible (CO{sub 2}{yields}C+O{sub 2}=C+O{sub 2}{yields}CO{sub 2}). The left-hand side represents the work of plants to remove atmospheric CO{sub 2}. The right-hand side represents the work of humans as fossil fuel consumers to produce it. The exchange of the two currencies is possible by copying the fossil fuel market. The paper concludes that this new exchange can automatically contain global warming and deforestation, replacing onerous emissions trading. Moreover, it could revolutionize the conventional economy, creating counter-capitalism, or &apos;carbonism&apos;.

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

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

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

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

To assess the intraobserver, interobserver, and test-retest reproducibility of minimum joint space width (mJSW) measurement of medial and lateral patellofemoral joints on standing &apos;'skyline'&apos; radiographs and to compare the mJSW of the patellofemoral joint to the mean cartilage thickness calculated by quantitative magnetic resonance imaging (qMRI). A couple of standing &apos;'skyline'&apos; radiographs of the patellofemoral joints and MRI of 55 knees of 28 volunteers (18 females, ten males, mean age, 48.5 {+-} 16.2 years) were obtained on the same day. The mJSW of the patellofemoral joint was manually measured and Kellgren and Lawrence grade (KLG) was independently assessed by two observers. The mJSW was compared to the mean cartilage thickness of patellofemoral joint calculated by qMRI. mJSW of the medial and lateral patellofemoral joint showed an excellent intraobserver agreement (interclass correlation (ICC) = 0.94 and 0.96), interobserver agreement (ICC = 0.90 and 0.95) and test-retest agreement (ICC = 0.92 and 0.96). The mJSW measured on radiographs was correlated to mean cartilage thickness calculated by qMRI (r = 0.71, p < 0.0001 for the medial PFJ and r = 0.81, p < 0.0001 for the lateral PFJ). However, there was a lack of concordance between radiographs and qMRI for extreme values of joint width and KLG. Radiographs yielded higher joint space measures than qMRI in knees with a normal joint space, while qMRI yielded higher joint space measures than radiographs in knees with joint space narrowing and higher KLG. Standing &apos;'skyline'&apos; radiographs are a reproducible tool for measuring the mJSW of the patellofemoral joint. The mJSW of the patellofemoral joint on radiographs are correlated with, but not concordant with, qMRI measurements. (orig.)

Polychlorinated biphenyls (PCBs) are potent persistent environmental pollutants exhibiting neurotoxic, teratogenic and tumor-promoting effects in experimental animal models. PCB congeners can be divided into &apos;dioxin-like&apos; and &apos;non-dioxin-like&apos; congeners on the basis of their ability to act as aryl hydrocarbon receptor (AhR) agonists. Like the most toxic dioxin congener 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) &apos;dioxin-like&apos; PCBs bind to the AhR and show characteristic effects on the expression of AhR-regulated genes including the induction of cytochrome P450 (CYP) 1A1. On the other hand, &apos;non-dioxin-like&apos; PCB congeners have a lower or no binding affinity to the AhR, but exhibit a &apos;phenobarbital-type&apos; induction of CYP 2B1/2 activity. The tumor-promoting potency of several PCBs has been demonstrated in two-stage initiation-promotion experiments in rat liver. Preneoplastic cell clones, targets for tumor promotion, can be identified as phenotypically altered foci showing characteristic enzyme patterns including the decreased activity of adenosine triphosphatase (ATPase) or the increased expression of the placental form of gluthatione S-transferase (GSTP). In the present study, the effect of the &apos;non-dioxin-like&apos; 2,4,4&apos;-trichlorobiphenyl (PCB 28) and 2,2&apos;,4,5,5&apos;-pentachlorobiphenyl (PCB 101) on the promotion of enzyme-altered hepatic foci was investigated in female Wistar rats after initiation with diethylnitrosamine (DEN).

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

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

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.

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.)

A potentiometric sensor based on the 1-benzyl-3-(4-nitrophenyl) thio-urea was synthesized and tested as an ionophore in PVC based membrane sensor towards SCN - ions. This membrane exhibits a linear stable response over a wide concentration range (1.0 × 10&apos;&apos;-5 to 1.0 × 10&apos;&apos;-2 M) with a slope of -59.2 mV/dec., a detection limit of log[SCN&apos;&apos;- ] = -5.05, and a selectivity coefficient for thiocyanate against perchlorate anion of logK{sub s}cn&apos;&apos;pot = -0.133. The selectivity series of the membrane is as follows: SCN&apos;&apos;- > ClO{sub 4}&apos;&apos;- > I&apos;&apos;- >NO{sub 3}&apos;&apos;- >HSO{sub 3}&apos;&apos;- > Cl&apos;&apos;-HSO{sub &apos;}'-'&apos;4 > F&apos;&apos;- > CH{sub 3}COO&apos;&apos;- > HCO&apos;'-'&apos;3 > Br&apos;&apos;- > H{sub 2}PO{sub 4}&apos;&apos;- > SO{sub 3}&apos;'-'&apos;2 > SO{sub 4}&apos;'-'&apos;2 > CO{sub 3}&apos;'-'&apos;2. The proposed electrode showed good selectivity and a good response for the SCN&apos;&apos;- ion over a wide variety of other anions in pH 6.0 buffer solutions and has a fast response time of about < 5s.. The influences of the membrane by pH, ionophore, and plasticizer were studied.

The role of science in the development of the so-called &apos;knowledge society&apos; was investigated at this interdisciplinary congress. Three problem areas were identified: 1. Science itself must constantly review its own ethical fundamentals and investigate and extend its ability to keep a dialogue running. 2. Society is asked to provide an ethical and moral orientation for dealing with newly acquired knowledge and to define the social standing of science. 3. Each and every individual must work on maintaining and extending his or her level of knowledge in order to cope with everyday life and perform social functions. [German] Ziel des Kongresses &apos;&apos;Bildung durch Wissenschaft&apos;&apos; war es, im interdisziplinaeren Austausch die Rolle der Wissenschaft bei der Entwicklung der so genannten &apos;'Wissensgesellschaft'&apos; zu eroertern. Der enorme Wissenszuwachs des vergangenen Jahrhunderts bedeutet eine Zunahme des &apos;'Machbaren'&apos;, von dessen positiven wie negativen Folgen die Gesellschaft und der Einzelne gleichermassen betroffen ist. Das gilt gerade fuer diejenigen Technologien und Wissensbestaende, die im Alltag von Bedeutung sind. Der Kongress beschaeftigte sich mit diesen Entwicklungen und mit den Problemen, die sich daraus ergeben. Der erste Problemkreis betrifft die Wissenschaft selbst: Sie muss sich ihrer eigenen ethischen Grundlagen wieder neu vergewissern, ihre Dialogfaehigkeit ueberpruefen und erweitern. Ein zweiter Problemkreis ist auf Seiten der Oeffentlichkeit auszumachen: Die Gesellschaft wird ethische und moralische Orientierungen fuer den Umgang mit dem neu erworbenen Wissen schaffen und grundsaetzlich den gesellschaftlichen Stellenwert der Wissenschaft bestimmen muessen. Der dritte Problemkreis stellt sich dem Einzelnen: Jeder ist gefordert, kontinuierlich sein Wissensniveau zu erhalten und zu erweitern, um den Alltag bewaeltigen und gesellschaftliche Aufgaben wahrnehmen zu koennen.

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

Acetabular retroversion as a rare cause of chronic hip pain: recognition of the &apos;'figure-eight'&apos; sign

While well-recognized in the orthopedic literature as a cause of chronic hip pain, acetabular retroversion has not been specifically described in the radiologic literature. Acetabular retroversion represents a particular form of hip dysplasia characterized by abnormal posterolateral orientation of the acetabulum. This pathophysiology predisposes the individual to subsequent anterior impingement of the femoral neck upon the anterior acetabular margin and fibrous labrum. Without treatment, cases may progress to damage of the anterior labrum and cartilage, with eventual early onset of osteoarthritic disease. This impinging condition has been described as occurring in isolation or as part of a complex dysplasia. We describe two cases of acetabular retroversion diagnosed by conventional radiographic evaluation of the pelvis, one in isolation and one occurring in the setting of a larger congenital syndrome. These cases illustrate the utility of the &apos;'figure-eight'&apos; sign in identifying abnormalities of acetabular version and thus assisting clinicians in properly identifying these individuals so that appropriate therapy may be instituted.

Germany steps up pressure on Fessenheim, but is the &apos;Energiewende&apos; all-knowing?

2015-01-01

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

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.

The &apos;last mile&apos; of data handling: Fermilab&apos;s IFDH tools

International Nuclear Information System (INIS)

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.

Full Text Available OBJETIVO: São vários os fatores que contribuem para a má adesão ao tratamento de crianças e adolescentes com doenças reumáticas crônicas, gerando piora da qualidade de vida e do prognóstico. Nosso objetivo foi avaliar as taxas de adesão ao tratamento e identificar os fatores socioeconômicos e clínicos associados. MÉTODOS: Foram incluídos 99 pacientes com artrite idiopática juvenil, lúpus eritematoso sistêmico, dermatomiosite ou esclerodermia juvenil. Todos os pacientes eram acompanhados no ambulatório de reumatologia pediátrica por um período mínimo de 6 meses. Para avaliação da adesão, foi aplicado aos cuidadores um questionário composto por três blocos: 1 dados demográficos, clínicos e laboratoriais; 2 adesão ao tratamento medicamentoso; e 3 comparecimento às consultas, realização de exames e utilização de órteses. Foi considerada má adesão, quando realizado valor menor ou igual a 80% do prescrito. RESULTADOS: Um total de 53% dos pacientes apresentou boa adesão ao tratamento global, observada quando o cuidador possuía união estável (p = 0,006; 20 pacientes (20,2% apresentaram má adesão ao tratamento medicamentoso, relacionada à utilização de mais que três medicamentos diários (p = 0,047. As causas de má adesão ao tratamento foram esquecimento, recusa, dose incorreta ou falta de medicamento, problemas pessoais e dificuldades financeiras. CONCLUSÕES: Observamos boa adesão ao tratamento global nos pacientes cujos cuidadores possuíam união estável e má adesão ao tratamento medicamentoso nos pacientes que utilizavam mais que três tipos de medicamentos diariamente. Não houve associação entre as taxas de adesão ao tratamento e sexo, idade, tempo de diagnóstico e atividade da doença.

Experimental data suggest that apolipoprotein (apo) C-II and C-III regulate triglyceride-rich lipoprotein (TRL) metabolism, but there are limited studies in humans. We investigated the metabolic associations of TRLs with apoC-II and apoC-III concentrations and kinetics in women. The kinetics of plasma apoC-II, apoC-III and very low-density lipoprotein (VLDL) apoB-100 and triglycerides were measured in the postabsorptive state using stable isotopic techniques and compartmental modelling in 60 women with wide-ranging body mass index (19·5-32·9 kg/m(2) ). Plasma apoC-II and apoC-III concentrations were positively associated with the concentrations of plasma triglycerides, VLDL1 - and VLDL2 -apoB-100 and triglyceride (all P triglyceride concentration and VLDL1 triglyceride PR, while apoC-II fractional catabolic rate (FCR) was positively associated with VLDL1 triglyceride FCR (all P triglyceride kinetics. ApoC-III PR, but not FCR, was positively associated with VLDL1 triglyceride, and VLDL2 -apoB-100 and triglyceride concentrations (all P triglyceride kinetics. In multivariable analysis, including homoeostasis model assessment score, menopausal status and obesity, apoC-II concentration was significantly associated with plasma triglyceride, VLDL1 -apoB-100 and VLDL1 triglyceride concentrations and PR. Using the same multivariable analysis, apoC-III was significantly associated with plasma triglyceride and VLDL1 - and VLDL2 -apoB-100 and triglyceride concentrations and FCR. In women, plasma apoC-II and apoC-III concentrations are regulated by their respective PR and are significant, independent determinants of the kinetics and plasma concentrations of TRLs. © 2016 Stichting European Society for Clinical Investigation Journal Foundation.

The Palestinian Authority and &apos;Climate Change&apos; as an Emergent Public Problem

International Nuclear Information System (INIS)

Fustec, Klervi

2014-01-01

&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?

Baseline for trust: defining &apos;new and additional&apos; climate funding

Energy Technology Data Exchange (ETDEWEB)

Stadelmann, Martin [University of Zurich (Switzerland); Roberts, J. Timmons [Brown University (United States); Huq, Saleemul

2010-06-15

Climate finance is becoming a dark curve on the road from Copenhagen to Cancún. Poorer nations fear that richer ones will fulfil the US$30 billion &apos;fast-start&apos; climate finance promises made in the non-binding Copenhagen Accord by relabelling or diverting basic development aid, or by simply delivering on past climate finance pledges. The problem is simple: contributor countries are operating with no clear baseline against which their promise of &apos;new and additional&apos; funding can be counted – and they do not accept the baselines put forth by developing countries. A viable solution for the short term is to use projections of business-as-usual development assistance as baselines. The longer-term benchmark could be the provision of truly &apos;new&apos; funds from new funding sources. Substantial up-front negotiations may be required, but seizing this opportunity to define baselines will build confidence on both sides and create predictability for future finance.

Full Text Available Alterações discretas na qualidade da voz e da articulação podem ser observadas em fases relativamente iniciais da doença de Parkinson (DP. As alterações da voz e da fala na DP constituem, em conjunto, o que se denomina disartria hipocinética ou disartrofonia e caracterizam-se por monotonia e redução da intensidade da voz, articulação imprecisa e distúrbios do ritmo. Recentemente, foram relatados resultados favoráveis através de método de tratamento intensivo e dirigido especificamente para o tratamento da voz na DP, denominado Lee Silverman Voice Treatment (LSVT®. O objetivo essencial desse método é aumentar a intensidade vocal através do incremento do esforço fonatório. O presente estudo teve por objetivo a caracterização das anormalidades vocais (qualidade vocal, padrão articulatório e inteligibilidade em um grupo de pacientes com DP e a avaliação da resposta terapêutica obtida pela administração do método Lee Silverman. A comparação dos dados de análise acústica, bem como da análise perceptivo-auditiva nos períodos pré e pós-tratamento mostraram modificações estatisticamente significantes após o tratamento. Embora o padrão articulatório tenha se mantido impreciso, os benefícios obtidos pelo tratamento na melhora da qualidade vocal e, sobretudo, na intensidade vocal favoreceram a qualidade da comunicação oral, reduziram os sintomas negativos e adequaram a qualidade vocal às necessidades pessoais e sociais dos indivíduos.

&apos;Chernobyl&apos; reaches Norway: the accident, science, and the threat to cultural knowledge

Paine, R. (Memorial Univ. of Newfoundland, St. John' s, NF (Canada))

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.

This updating of the &apos;&apos;Future offshore sites for wind turbines 2025&apos;&apos;, is made by the Offshore Wind Farm Committee and adjusts primarily the existing sites in relation to a updated data basis. The sites are adjusted within the already identified areas, and no new areas are therefore included. In addition to an update of the underlying data base, including the revised sailing routes, the new Natura 2000 sites and mineral resources, there are now further collected knowledge about the seabed in the designated areas. Moreover, the underlying assumptions for construction costs and grid connection updated, which has resulted in a revised socio-economic priority of the areas. The Offshore Wind Farm Committee&apos;s report confirms that the placement of the 600 MW Kriegers Flak Offshore Wind Farm in the Baltic Sea is the best location for Denmark&apos;s next major offshore wind farm. Kriegers Flak Offshore Wind Farm is already included in the Government&apos;s energy strategy. (LN)

The &apos;&apos;2T&apos;&apos; ion-electron semi-analytic shock solution for code-comparison with xRAGE: A report for FY16

Ferguson, Jim Michael

2016-01-01

This report documents an effort to generate the semi-analytic &apos;2T&apos; ion-electron shock solution developed in the paper by Masser, Wohlbier, and Lowrie, and the initial attempts to understand how to use this solution as a code-verification tool for one of LANL&apos;s ASC codes, xRAGE. Most of the work so far has gone into generating the semi-analytic solution. Considerable effort will go into understanding how to write the xRAGE input deck that both matches the boundary conditions imposed by the solution, and also what physics models must be implemented within the semi-analytic solution itself to match the model assumptions inherit within xRAGE. Therefore, most of this report focuses on deriving the equations for the semi-analytic 1D-planar time-independent &apos;2T&apos; ion-electron shock solution, and is written in a style that is intended to provide clear guidance for anyone writing their own solver.

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.

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.)

ApoliopoproteinE Ɛ4 (ApoE-Ɛ4) polymorphism is the most well known genetic risk factor for developing Alzheimers Disease. The exact mechanism through which ApoE 4 increases AD risk is not fully known, but may be related to decreased clearance and increased oligomerization of Aβ. By making measurements of white matter integrity via diffusion MR and correlating the metrics in a voxel-based statistical analysis with ApoE-Ɛ4 genotype (whilst controlling for vascular risk factor, gender, cognitive status and age) we are able to identify changes in white matter associated with carrying an ApoE Ɛ4 allele. We found potentially significant regions (Puncorrected cognitive decline via a pathway in dependent of normal aging and acute insults that can be measured by CDR and Framingham Coronary Risk Score (FCRS).

The EURATOM FP7 Collaborative Project &apos;&apos;Fast / Instant Release of Safety Relevant Radionuclides from Spent Nuclear Fuel (CP FIRST-Nuclides)&apos;&apos; started in January 1, 2012 and extends over 3 years. The European nuclear waste management organisations contributing to the Technology Platform &apos;&apos;Implementing Geological Disposal (IGD-TP)&apos;&apos; considered the fast / instant release of safety relevant radionuclides from high burn-up spent nuclear fuel as one of the key topics in the deployment plan. For this reason, the CP FIRST-Nuclides deals with understanding the behaviour of high burn-up uranium oxide (UO{sub 2}) spent nuclear fuels in deep geological repositories. The fast / instant release of radionuclides from spent nuclear fuel was investigated in a series of previous European. In addition, there were several studies mainly of the French research programs that investigated and quantified the rapid. However, several important issues are still open and consequently, the CP FIRST-Nuclides aims on covering this deficiency of knowledge, determining, for example, the &apos;&apos;instant release fraction (IRF)&apos;&apos; values of iodine, chlorine, carbon and selenium that are still largely unknown. Fuel elements from different Light Water Reactors (LWRs), with different enrichments, burn-up and average power rates need to be disposed of in Europe. This waste type represents one of the sources for the release of radionuclides after loss of integrity of a disposed canister. The quantification of time dependent release of radionuclides from spent high burn-up UO{sub 2} fuel is required for safety analyses. The first release fraction consists of radionuclides in gaseous form, and those showing a high solubility in groundwater. LWRs use conventional oxide fuels with initial enrichments of up to 5 wt.% {sup 235}U for reaching average burn-up of ≤ 60 GWd/t{sub HM}. During the use of UO{sub 2} in a reactor, a significantly higher burn-up takes

A novel porphyrin-C{sub 60} dyad (PCD1) is designed and synthesized to investigate and manipulate the supramolecular structure where geometrically isotropic [such as [60]fullerene (C{sub 60})] and anisotropic [such as porphyrin (Por)] units coexist. It is observed that PCD1 possesses an enantiomeric phase behavior. The melting temperature of the stable PCD1 thermotropic phase is 160 C with a latent heat ({Delta}H) of 18.5 kJ mol{sup -1}. The phase formation is majorly driven by the cooperative intermolecular Por-Por and C{sub 60}-C{sub 60} interactions. Structural analysis reveals that this stable phase possesses a supramolecular &apos;'double-cable'&apos; structure with one p-type Por core columnar channel and three helical n-type C{sub 60} peripheral channels. These &apos;'double-cable'&apos; columns further pack into a hexagonal lattice with a = b = 4.65 nm, c = 41.3 nm, {alpha} = {beta} = 90 , and {gamma} = 120 . The column repeat unit is determined to possess a 129{sub 44} helix. With both donor (D; Pro) and acceptor (A; C{sub 60}) units having their own connecting channels as well as the large D/A interface within the supramolecular &apos;'double-cable'&apos; structure, PCD1 has photogenerated carriers with longer lifetimes compared to the conventional electron acceptor [6,6]-phenyl-C{sub 61}-butyric acid methyl ester. A phase-separated columnar morphology is observed in a bulk-heterojunction (BHJ) material made by the physical blend of a low band-gap conjugated polymer, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta [2,1-b;3,4-b&apos;]-dithiophene)-alt-4,7-(2,1,3-benzothia-diazole)] (PCPDTBT), and PCD1. With a specific phase structure in the solid state and in the blend, PCD1 is shown to be a promising candidate as a new electron acceptor in high performance BHJ polymer solar cells.

Laplace&apos;s equation and Faraday&apos;s lines of force

Energy Technology Data Exchange (ETDEWEB)

Narasimhan, T.N.

2007-06-01

Boundary-value problems involve two dependent variables: a potential function, and a stream function. They can be approached in two mutually independent ways. The first, introduced by Laplace, involves spatial gradients at a point. Inspired by Faraday, Maxwell introduced the other, visualizing the flow domain as a collection of flow tubes and isopotential surfaces. Boundary-value problems intrinsically entail coupled treatment (or, equivalently, optimization) of potential and stream functions Historically, potential theory avoided the cumbersome optimization task through ingenious techniques such as conformal mapping and Green&apos;s functions. Laplace&apos;s point-based approach, and Maxwell&apos;s global approach, each provides its own unique insights into boundary-value problems. Commonly, Laplace&apos;s equation is solved either algebraically, or with approximate numerical methods. Maxwell&apos;s geometry-based approach opens up novel possibilities of direct optimization, providing an independent logical basis for numerical models, rather than treating them as approximate solvers of the differential equation. Whereas points, gradients, and Darcy&apos;s law are central to posing problems on the basis of Laplace&apos;s approach, flow tubes, potential differences, and the mathematical form of Ohm&apos;s law are central to posing them in natural coordinates oriented along flow paths. Besides being of philosophical interest, optimization algorithms can provide advantages that complement the power of classical numerical models. In the spirit of Maxwell, who eloquently spoke for a balance between abstract mathematical symbolism and observable attributes of concrete objects, this paper is an examination of the central ideas of the two approaches, and a reflection on how Maxwell&apos;s integral visualization may be practically put to use in a world of digital computers.

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

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.

Atualmente destaca-se por ser a segunda bebida alcoólica mais consumida no Brasil e a terceira destilada no mundo. Diversos fatores afetam negativamente a cadeia produtiva, entre eles o tratamento do caldo e a levedura utilizada. Neste sentido, o objetivo do trabalho foi avaliar a influência do tipo de fermento e o tratamento do caldo sobre a qualidade do destilado. O experimento foi realizado na safra 2014/2015, utilizando-se a variedade SP83-2847. O delineamento experimental foi inteiramente casualizado com parcelas subdivididas, com 9 repetições. As parcelas foram constituídas pelo modo de tratamento do caldo (caldo clarificado e não clarificado e as subparcelas os tipos de fermento (Natural e CA-11. Foram determinadas características químicas do mosto, como Sólidos Solúveis Totais (SST, Compostos Fenólicos Totais (CFT, Açúcares Redutores Totais (ART e Acidez Total. No processo fermentativo avaliou-se a viabilidade das células e brotos e o índice de brotamentos. No vinho determinou-se o SST, ARRT, pH, acidez total, teor alcoólico, glicerol e eficiência fermentativa. Determinou-se a composição das cachaças através da quantificação de aldeídos totais, ésteres totais, metanol, acroleína, carbamato de etila, furfural, acidez volátil e coeficiente de congêneres. Analisou-se ainda condutividade elétrica, turbidez e pH, sendo os componentes secundários determinados por cromatografia gasosa. O tratamento prévio do caldo resultou em mosto de condições ideais para a levedura. A levedura CA-11 apresentou maiores teores de viabilidade celular. A associação entre tratamento de caldo e uso de fermento selecionado resulta em cachaça de composição mais equilibrada.

Full Text Available Geriatricians and general practitioners often follow patients with metastatic prostate cancer. The epidemiology and basic treatment principles of metastatic prostate cancer are discussed aiming to update the topic for the non-oncologist. Hormone manipulation remains the basis of treatment, usually up to a second line of therapy. Selected cases are treated successfully with intermittent androgen ablation. When new hormone-independent clones arise, chemotherapy should be added to therapy that confers improved survival as well as better quality of life when based on taxanes. In specific situations, additional measures such as bisphosphonates and radiation therapy should be included in the treatment. As a rule, the public health system makes available the necessary medication to ensure treatment for the vast majority of patients in Brazil.Pacientes com câncer de prostata metastático estão freqüentemente sob os cuidados de geriatras e clínicos gerais. Discutimos a epidemiologia e os princípios básicos do tratamento do câncer de próstata metastático, visando atualizar o não-oncologista no assunto. A base do tratamento continua sendo a manipulação hormonal, inclusive como tratamento de segunda linha. Casos selecionados podem ser tratados com ablação androgênica intermitente de maneira eficaz. Quando se desenvolvem clones de células hormônio-independentes, quimioterápicos são incorporados na terapia. A quimioterapia confere não só benefício em sobrevida, mas também na qualidade de vida, quando baseado em taxanos. Medidas adicionais como o uso de bisfosfonados e radioterapia devem ser incorporadas no tratamento em situações especiais. De modo geral, o sistema público de saúde do Brasil disponibiliza todas as medicações necessárias ao adequado tratamento dos pacientes no país.

&apos;&apos;Atomic Optics&apos;&apos;: Nonimaging Optics on the Nanoscale

Energy Technology Data Exchange (ETDEWEB)

Roland Winston Joseph O' Gallagher

2005-01-15

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

Magnetic objects can cause local variations in the Earth&apos;s magnetic field that can be measured with a magnetometer. Here we used tri-axial magnetometer measurements and an analysis method employing wavelet techniques to determine the &apos;signature&apos; or &apos;fingerprint&apos; of different iron objects. Clear distinctions among the iron samples were observed. The time-dependent changes in the frequency powers were extracted by use of the Morlet wavelet corresponding to frequency bands from 0.1 to 100 Hz.

We report on the case of a 70-year-old woman presenting with right hip pain. Radiographs of the right hip demonstrated a well-defined large lytic lesion in the proximal right femur, with prominent trabeculae situated peripherally and extending into the lesion in a &apos;spoke-wheel&apos; pattern. Magnetic resonance imaging (MRI) demonstrated solid enhancing marrow-replacing lesion, with intervening linear nonenhancing areas of low T2 signal intensity. The MRI appearance resembled that of a small brain or &apos;mini brain&apos;. Biopsy specimen demonstrated predominantly mature plasma cells, with occasional admixed immature forms. A diagnosis of plasmacytosis, consistent with myeloma, was made. This case illustrates a rare but seemingly characteristic &apos;mini brain&apos; appearance of plasmacytoma, which, to date, has only been reported in the spine and has not been observed in other bony lesions.

Apolipoprotein E (apoE) is a major carrier of cholesterol and essential for synaptic plasticity. In brain, it's expressed by many cells but highly expressed by the choroid plexus and the predominant apolipoprotein in cerebrospinal fluid (CSF). The role of apoE in the CSF is unclear. Recently, the glymphatic system was described as a clearance system whereby CSF and ISF (interstitial fluid) is exchanged via the peri-arterial space and convective flow of ISF clearance is mediated by aquaporin 4 (AQP4), a water channel. We reasoned that this system also serves to distribute essential molecules in CSF into brain. The aim was to establish whether apoE in CSF, secreted by the choroid plexus, is distributed into brain, and whether this distribution pattern was altered by sleep deprivation. We used fluorescently labeled lipidated apoE isoforms, lenti-apoE3 delivered to the choroid plexus, immunohistochemistry to map apoE brain distribution, immunolabeled cells and proteins in brain, Western blot analysis and ELISA to determine apoE levels and radiolabeled molecules to quantify CSF inflow into brain and brain clearance in mice. Data were statistically analyzed using ANOVA or Student's t- test. We show that the glymphatic fluid transporting system contributes to the delivery of choroid plexus/CSF-derived human apoE to neurons. CSF-delivered human apoE entered brain via the perivascular space of penetrating arteries and flows radially around arteries, but not veins, in an isoform specific manner (apoE2 > apoE3 > apoE4). Flow of apoE around arteries was facilitated by AQP4, a characteristic feature of the glymphatic system. ApoE3, delivered by lentivirus to the choroid plexus and ependymal layer but not to the parenchymal cells, was present in the CSF, penetrating arteries and neurons. The inflow of CSF, which contains apoE, into brain and its clearance from the interstitium were severely suppressed by sleep deprivation compared to the sleep state. Thus, choroid plexus

Linoleum: a &apos;green&apos; flooring option

Energy Technology Data Exchange (ETDEWEB)

Anon

2002-07-01

&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.

Fatigue due to vortex-induced vibrations (VIV) is one of the major uncertainties today in the design of slender offshore structures, such as risers, pipelines, umbilicals, tendons and mooring lines, required for oil and gas production in deep waters. The absence of reliable tools for quantitative analyses of this phenomenon is a technological barrier, which is being faced by several research groups, generating tens of thesis and articles every year. This paper presents VIV results achieved by the author, using &apos;wake oscillator&apos; and &apos;vortex tracking&apos; models, when researching for his M. Sc. dissertation. Time domain analyses were performed using a commercial software. First results describe the response of the evaluated models for two degrees-of-freedom rigid cylinders, which were compared to values prescribed in recognized recommended practices. Afterwards, VIV analyses results for a steel catenary 10-inch diameter riser in three dimensional current profiles were compared to measured values. The considered riser, installed in 910 m water depth offshore Brazil, is possibly the only monitored SCR with no VIV suppression devices in the world today. The results were considered satisfactory, despite some discrepancies. The authors expect the presented results to contribute in further studies on these models. (author)

&apos;Mote&apos; networks; A nano SWAT team for the oilpatch

Energy Technology Data Exchange (ETDEWEB)

Ross, E.

2004-05-01

&apos;Motes&apos; are tiny sensor modules which make up wireless sensor networks for monitoring parameters such as energy use or temperature. Motes have the capacity for self-configuring a network, self-correct without downtime if there is an interruption in the connection, and for transferring information using the fastest and most reliable path in sending data to the control system via a gateway. Dust Incorporated, a technology company based in Berkeley, California, employs motes to communicate with each other in a self-healing, self-organizing way, and to do so at the lowest possible cost. At present, motes are used mainly in defence and industrial monitoring applications, however the company is exploring potential applications in the oilpatch in facilities that include pumping stations, pipelines, or remote areas, unattended for long periods of time. Application in perimeter security systems is also being explored. Key to the technology is the concept of mesh networks: i.e. instead of each mote having a single channel back to a backbone, the system has multiple paths, able to find another path if one route fails. In the oil and gas industry one of the most promising applications so far has been use as a &apos;rapid profiling kit&apos; in which the network could be used to augment rough measurements with measurements of a higher resolution. Another application contemplated is use of mote networks in monitoring the health of machines by &apos;listening for crunching or knocking&apos;. Low power requirement is the key to success in wireless systems; accordingly, Dust Corporation&apos;s objective is to perfect the timing and radio transmission rates to the point where the modules can operate for five to ten years on two &apos;AA&apos; batteries.

Aluminum-nitrogen six-fold octahedral coordination, [AlN{sub 6}], is unusual and has only been seen in the high-pressure rocksalt-type aluminum nitride or some complex compounds. Herein we report novel nitrides LnAl(Si{sub 4-x}Al{sub x})N{sub 7}O{sub δ} (Ln=La, Sm), the first inorganic compounds with [AlN{sub 6}] coordination prepared via non-high-pressure synthesis. Structure refinements of neutron powder diffraction and single-crystal X-ray diffraction data show that these compounds crystallize in the hexagonal Swedenborgite structure type with P6{sub 3}mc symmetry where Ln and Al atoms locate in anticuboctahedral and octahedral interstitials, respectively, between the triangular and Kagome layers of [SiN{sub 4}] tetrahedra. Solid-state NMR data of high-purity La-114 powders confirm the unusual [AlN{sub 6}] coordination. These compounds are the first examples of the &apos;&apos;33-114&apos;&apos; sub-type in the &apos;&apos;114&apos;&apos; family. The additional site for over-stoichiometric oxygen in the structure of 114-type compounds was also identified. (copyright 2017 Wiley-VCH Verlag GmbH and Co. KGaA, Weinheim)

Os processos empregados no tratamento foram: tratamento primário (reatores anaeróbios, tratamento secundário/terciário (Wetlands construídos - WC’s e tratamento final (sistema de desinfecção Ultra Violeta - UV. Entre os meses de dezembro e junho de 2012, foram coletadas 30 amostras de cinco fases distintas (Bruto - P1, Água da Chuva - P2, Reator anaeróbico de fluxo ascendente e manta de lodo (UASB - P3, WC’s-P4 e desinfecção com UV - P5. Os resultados indicaram toxicidade aguda em P1, com uma CE(I50% 48h de 25,8 ± 23,64% (n = 6; CV = 109,2%, correspondendo a uma amostra altamente tóxica. Nos pontos P2 e P3, as amostras apresentaram uma CE(I50% 48h de 5,1% ± 3,5% (n = 6; CV = 145,7% e 36,7 ± 23,9% (n = 6; CV = 153,5%, correspondendo a uma amostra extremamente tóxica e altamente tóxica, respectivamente. Os efluentes dos pontos P4 (n = 6 e P5 (n = 6 não apresentaram toxicidade. Desta forma, os resultados demonstraram a eficiência da capacidade de detoxificação dos processosWC’s e UV.

Crisis - Weisskopf&apos;s view

&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

Cp{sup &apos;}{sub 4}U (Cp{sup &apos;} = C{sub 5}H{sub 4}SiMe{sub 3}) was synthesized from: (a) KCp{sup &apos;} and [Cp{sup &apos;}{sub 3}U(THF)][BPh{sub 4}]; (b) Cp{sup &apos;}{sub 3}U and Cp{sup &apos;}{sub 2}Pb; and (c) [K(2.2.2-cryptand)][Cp{sup &apos;}{sub 4}U] and AgBPh{sub 4}. The compound was identified by X-ray crystallography as a rare example of a structurally-characterized tetrakis(cyclopentadienyl)U{sup IV} complex. For comparison, the corresponding Th complex, Cp{sup &apos;}{sub 4}Th, was isolated from the direct combination of ThBr{sub 4}(THF){sub 4} with excess KCp{sup &apos;}. During the preparation of Cp{sup &apos;}{sub 3}UMe, the precursor of the [Cp{sup &apos;}{sub 3}U(THF)][BPh{sub 4}] reagent used above, it was discovered that the reaction of Cp{sup &apos;}{sub 3}UCl and MeLi gives a mixture of Cp{sup &apos;}{sub 3}UMe and Cp{sup &apos;}{sub 3}UCl that can co-crystallize better than Cp{sup &apos;}{sub 3}UMe in pure form. The Cp&apos;{sub 3}UMe/Cp{sup &apos;}{sub 3}UCl mixture forms single crystals suitable for X-ray crystallography and provides a new way to characterize the oil, Cp{sup &apos;}{sub 3}UMe. Cp{sup &apos;}{sub 3}UCl and Cp{sup &apos;}{sub 3}UI were also crystallographically characterized for comparison with the Cp{sup &apos;}{sub 3}UMe/Cp{sup &apos;}{sub 3}UCl crystals.
