    Full Text Available OBJECTIVE: To analyze household health expenditures on children who are beneficiaries of the Medical Insurance for a New Generation (SMNG, program created in 2007 to cover healthcare costs of children without social security born after December 1st, 2006. MATERIALS AND METHODS: Using the SMNG National Survey, out-the-pocket and catastrophic spending on child health were calculated using several definitions. Results are presented by socioeconomic level, rural and urban areas and for Oportunidades beneficiaries. RESULTS: About 63.3% of households spent an average annual amount of 3320 Mexican pesos (MEX$ on healthcare for beneficiary children. Between 4.3 and 11.6% of households experienced catastrophic spending, depending on the definition adopted. Due to economic trouble, 15.5% of households postponed and 10.0% cancelled medical care for their child. CONCLUSIONS: Even though children are affiliated to the SMNG, the economic burden associated with attending their health is still an issue for families.OBJETIVO: Analizar el gasto en salud y gasto catastrófico en los niños beneficiarios del Seguro Médico para una Nueva Generación (SMNG, programa creado en 2007 para niños sin seguridad social nacidos a partir del 1o de diciembre de 2006.

    Full Text Available OBJETIVO: Estimar el gasto de los hogares durante la primera hospitalización en 51 menores de 15 años de edad con leucemia, atendidos en dos hospitales del Instituto Mexicano del Seguro Social, en México durante 1997. MATERIAL Y MÉTODOS: Estudio transversal hecho en 1997 en el Distrito Federal y en León, Guanajuato. Se aplicó un cuestionario a los padres de 51 menores de 15 años de edad con diagnóstico de leucemia, hospitalizados por primera vez, en dos unidades del Instituto Mexicano del Seguro Social. Se capturó la información de los costos directos e indirectos enfrentados por los hogares durante esa primera hospitalización. Se aplicó el Indice de Precios al Consumidor (1997-2002 para expresar las estimaciones en precios de 2002. Se estimaron indicadores de gasto promedio y gastos catastróficos. Se establecieron los factores asociados, mediante un modelo de regresión lineal, utilizando el gasto total durante la hospitalización como variable dependiente. RESULTADOS: El costo promedio por paciente hospitalizado es de 7 318 pesos. El 86% corresponde a gastos asociados con la atención y 14% a costos indirectos. Para 14% de los hogares este gasto fue catastrófico. En 47% de los casos la erogación rebasó 100% de su ingreso disponible durante el periodo. Estos gastos se asociaron con lugar de residencia, nivel de ingreso y tipo de seguro. CONCLUSIONES: Ser derechohabiente de la seguridad social reduce los gastos de bolsillo por atención directa de los pacientes, pero no reduce los gastos complementarios, que pueden resultar onerosos para una elevada proporción de hogares. El costo de la primera hospitalización significó, en más de la mitad de los casos estudiados, el consumo de los ahorros, el endeudamiento o la venta de propiedades de los hogares, y dificultó la continuidad del tratamiento.

    Full Text Available OBJETIVO: O artigo analisa a participação do gasto privado com saúde das famílias no PIB e no total da renda familiar per capita e a distribuição do gasto privado com saúde das famílias por classes de renda. MÉTODOS: A pesquisa utilizou os microdados da Pesquisa Nacional por Amostra de Domicílios de 1998, com a divisão da população em quatro classes de renda familiar per capita e a distribuição dos gastos em planos de saúde, consultas médicas, consultas com outros profissionais de saúde, exames, medicamentos, artigos ortopédicos e aparelhos médicos, óculos e lentes, odontologia, hospitais, enfermagem domiciliar e outros gastos com saúde. RESULTADOS: Apenas 7,2% da população com renda familiar per capita até 1 salário mínimo em 1998 tinha direito a algum plano de saúde, e o gasto privado com saúde das famílias desta classe, que representava 52,5% da população, era em média de R$ 5,36 por pessoa. Para as pessoas com renda familiar per capita acima de 9 salários mínimos, os planos de saúde atingiam 83,2% da população e o gasto privado com saúde das famílias R$ 133,04. CONCLUSÕES: A implantação do Sistema Único de Saúde foi acompanhada pelo crescimento expressivo dos planos de saúde nos anos 90. Mesmo se todo o gasto público com saúde fosse destinado à população sem planos de saúde, ainda assim o gasto destas pessoas em 1998 só alcançaria R$ 352,62, ou seja, 43% do gasto com saúde das pessoas com planos, R$ 819,08.

    Full Text Available Este trabalho dimensiona e analisa o gasto em educação básica; em que níveis e modalidades foram aplicados os recursos; a responsabilidade de cada ente federado pelo gasto educacional; e a prioridade econômica voltada à educação. De modo geral, constatou-se que o sistema de financiamento dos gastos das políticas de educação conseguiu manter sua proteção contra cortes orçamentários, mas, em contrapartida, não permitiu ampliação da importância macroeconômica dos gastos da área educacional, revelando baixa prioridade de governo à educação. Além disso, foi possível verificar que a educação básica é muito importante na composição dos gastos educacionais, principalmente o ensino fundamental e que grande parte das ações governamentais tem caráter descentralizado.This paper helps identifying the amount of public expenditures allotted to basic education, the amount of resources applied to each education level and modality, the weight of each government level in public education funding and the priority given to education within the public budget. It shows that: 1 although the educational funding system has been spared from budget cuts, education expenditures have not increased their macroeconomic importance within the total public expenditures, which evidences that the government gives low priority to education; 2 most of the public educational expenditures are allotted to basic education, and more particularly to fundamental education; and finally 3 a great part of the government actions have been decentralized to the local level.

    Full Text Available In order to obtain a continuous control of the Butron river's discharge a stage graphic recorder was installed in its lower reaches, taking advantage of the previous existence of estage boards and a specially prepared bridge for making velocity measurements using a current meter. Several measurements of the stream discharge and the corresponding rating curve were also available, information that has been completed with aditional discharge measurements by dilution gauging (constant rate and gulp injection and by the velocity-area technique using a current meter. The all set of data allowed us to draw a new rating curve which adjust narrowly to a straight line for stages higher than 0.9 meters and more loosely to a curve for lower stages, This fact let us, after several attempts, to reduce this curve line to a series of 12 straight segments so that the automatic processing in microcomputer of the corresponding stage recorder charts were made possible.

    Para disponer del control continuo del caudal del río Butrón se instaló una estación limnigráfica en la parte final de su curso, aprovechando la existencia previa de escalas limnimétricas y de un puente especialmente acondicionado para la realización de aforos con molinete. Se disponía, además, de una serie de aforos directos y la curva de gastos correspondiente a los mismos, información que se ha completado con nuevos aforos químicos y con molinete. El conjunto de estos datos nos ha permitido trazar una nueva curva de gastos que ajusta aceptablemente a una recta para alturas de carga superiores a 0,9 metros y más deficientemente a una curva de segundo grado para alturas inferiores a dicho límite. Esta circunstancia aconsejó, después de varios intentos, descomponer dicho tramo curvo en un conjunto de 12 rectas, de modo que fuera posible el procesamiento automático en microordenador. de los limnigramas correspondientes.

Allí, se abordan dos grandes enfoques: el de endogeneidad y el de exogeneidad. El primero, afirma que el gasto es endógeno, elástico y procíclico frente al producto, mientras que el segundo lo considera exógeno y contracíclico. La primera perspectiva es conocida en la literatura económica como Ley de Wagner y, la segunda, obedece a un comportamiento keynesiano. No obstante, es importante subrayar que bajo estos dos escenarios se hace posible la existencia de un enfoque mixto, cuyas características obedecen a un comportamiento endógeno y contracíclico del gasto público frente al producto interno bruto (PIB. Los resultados sugieren que las series no son estacionarias, esto es, que son integradas de orden uno. Por su parte, el test de Cointegración de Johansen indica la existencia de una relación de largo plazo entre el PIB y el gasto público. Además, se encuentra un fuerte respaldo a la Ley de Wagner, debido a que la dirección de causalidad va del PIB al gasto público y los coeficientes de elasticidad son positivos y significativos.

    Full Text Available O artigo discute como a política fiscal, através dos gastos em educação, afeta a acumulação de capacidades e o nível de emprego. Desse modo, o gasto público pode afetar a produtividade e ter efeitos que vão além daqueles diretos sobre a demanda efetiva. O efeito sobre a produtividade deriva do fato de que parte do gasto público se destina à educação e ao treinamento dos trabalhadores. São discutidos os efeitos da política fiscal sobre o emprego, a produtividade e o crescimento, e as implicações de política do modelo. Neste artigo pretende-se analisar como a política fiscal, via gastos em educação, pode afetar a acumulação de capital humano e o nível de produtividade de um país e, consequentemente, alterar o nível de emprego e catalisar o crescimento econômico. A contribuição teórica proposta advém do fato de que a questão central é incluir uma nova dimensão, ou seja, a possibilidade de que o gasto público possa contribuir para os aumentos da produtividade. Isto é, o gasto do governo tem um efeito que vai além da demanda efetiva; ele pode afetar também a produtividade do trabalho, agora não mais constante. Neste modelo admitiremos que certa parcela do gasto público seja investida em educação. Dessa forma, se estabelece um vínculo entre política fiscal, educação e produtividade. A partir daí, serão obtidos novos resultados em termos dos níveis de emprego, salário e produto, e suas implicações de política poderão ser analisadas.

    Recently proposed model potential which combines both linear and quadratic types of interactions is employed for the investigation of some properties like the total energy, equation of state and bulk modulus of AlP, AlAs and AlSb semiconductor compounds using higher-order perturbation theory. The model potential parameter is determined using zero pressure condition. The ratio of the covalent bonding term E cov to the second-order term 2 is 6.77% to 11.85% which shows that contribution from higher order terms are important for zinc-blende-type crystals. The calculated numerical results of the total energy, energy band gap at Jones-zone face and bulk modulus of these compounds are in good agreement with the experimental data and found much better than other such theoretical findings. We have also studied pressure–volume relations of these compounds. The present study is carried out using six different screening functions along with latest screening function proposed by Sarkar et al. It is found from the present study that effect of exchange and correlation is clearly distinguishable.

Foi calculado o valor per capita/ano do gasto federal em saúde mental. RESULTADOS: Observou-se o crescimento real de 51,3% do gasto em saúde mental no período. A desagregação do gasto revelou aumento expressivo do valor extra-hospitalar (404,2% e decréscimo do hospitalar (-39,5%. O gasto per capita teve crescimento real menor, embora expressivo (36,2%. A série histórica do gasto per capita desagregado mostrou que em 2006, pela primeira vez, o gasto extra-hospitalar foi maior que o hospitalar. O valor per capita extra-hospitalar teve o crescimento real de 354,0%; o valor per capita hospitalar decresceu 45,5%. CONCLUSÕES: Houve crescimento real dos recursos federais investidos em saúde mental entre 2001 e 2009 e investimento expressivo nas ações extra-hospitalares. Houve inversão no direcionamento dos recursos, a partir de 2006, na direção dos serviços comunitários. O componente do financiamento teve papel crucial como indutor da mudança de modelo de atenção em saúde mental. O desafio para os próximos anos é sustentar e aumentar os recursos para a saúde mental num contexto de desfinanciamento do Sistema Único de Saúde.

    Full Text Available OBJETIVO: Estimar el gasto de los hogares durante la primera hospitalización en 51 menores de 15 años de edad con leucemia, atendidos en dos hospitales del Instituto Mexicano del Seguro Social, en México durante 1997. MATERIAL Y MÉTODOS: Estudio transversal hecho en 1997 en el Distrito Federal y en León, Guanajuato. Se aplicó un cuestionario a los padres de 51 menores de 15 años de edad con diagnóstico de leucemia, hospitalizados por primera vez, en dos unidades del Instituto Mexicano del Seguro Social. Se capturó la información de los costos directos e indirectos enfrentados por los hogares durante esa primera hospitalización. Se aplicó el Indice de Precios al Consumidor (1997-2002 para expresar las estimaciones en precios de 2002. Se estimaron indicadores de gasto promedio y gastos catastróficos. Se establecieron los factores asociados, mediante un modelo de regresión lineal, utilizando el gasto total durante la hospitalización como variable dependiente. RESULTADOS: El costo promedio por paciente hospitalizado es de 7 318 pesos. El 86% corresponde a gastos asociados con la atención y 14% a costos indirectos. Para 14% de los hogares este gasto fue catastrófico. En 47% de los casos la erogación rebasó 100% de su ingreso disponible durante el periodo. Estos gastos se asociaron con lugar de residencia, nivel de ingreso y tipo de seguro. CONCLUSIONES: Ser derechohabiente de la seguridad social reduce los gastos de bolsillo por atención directa de los pacientes, pero no reduce los gastos complementarios, que pueden resultar onerosos para una elevada proporción de hogares. El costo de la primera hospitalización significó, en más de la mitad de los casos estudiados, el consumo de los ahorros, el endeudamiento o la venta de propiedades de los hogares, y dificultó la continuidad del tratamiento.OBJECTIVE: To estimate out-of-pocket expenditures for health care during the first hospitalization of children treated for leukemia in

Los dos tipos de medidas clasifican los beneficios de políticas como particularistas si son bienes exclusivos o si son explicados por variables políticas. Este artículo desarrolla un índice de gasto particularista en bienes públicos locales medido como desviación con respecto al programa. Se aplica el índice a la oferta de servicios básicos por administraciones subnacionales seleccionadas en México y Argentina. Se muestra que el índice corre menos riesgos de sobreestimar o subestimar el gasto particularista y el gasto programático que las medidas existentes.This article compares particularistic and programmed government spending. The two types of measures classify the benefits of policies as particularistic if they are exclusive goods or if they are determined by political variables. This article contains an index of particularistic expenditure on local public goods, measured as a deviation from the program. It applies this index to the supply of basic services from selected sub-national administrations in Mexico and Argentina. It shows that this index is less likely to over- or under-estimate particularistic and programmatic expenditure than existing measures.

    Influence of total aluminum concentration (CAlT) on the generation and transformation of nanosized Al13 and Al30 in hydrolytic polyaluminum aqueous solutions was investigated using high field 27Al NMR and time-developed Al-Ferron complex colorimetry. When prepared at the optimal basicity (B) of Al13 generation and 80℃, the Al13 species in polyaluminum solution tends to further polymerize and convert to Al30 and higher polymers when CAlT >0.2 mol·L-1, but Al13 does not convert to Al30 quantificationally, as the formation of Alu from Al13 and Al30 is accelerated in the same way. The conversion rate of Al13 is accelerated by the increase in CAlT. When CAlT >0.75 mol·L-1, Al13 content decreases rapidly, and Al30 content increases continuously and becomes the dominant nanometer polynuclear aluminum species. Alm is one of prerequisites of Al13 conversion to Al30. When CAlT increases and B reduces, the polymerization rate between Al13 and Alm increases, and at the same time, the dissociation reaction rate of Al13 and Al30 by H+ also increases. The latter becomes the dominant reaction in polyaluminum solution with low B value, so Al30 decreases with the increasing CAlT. The hydrolytic polyaluminum solution with Al13 content beyond 80% can only be prepared under the condition of CAlT<0.5 mol·L-1 and optimal B value.

El síntoma más obvio es que las familias enfrentan la ruina económica y el empobrecimiento por financiar su atención médica. México fue uno de los primeros países en diagnosticar el problema, atribuirlo a la falta de protección financiera y proponer una terapia sistémica a través de la reforma del sistema de salud. Este trabajo analiza la manera en que México convirtió las evidencias sobre los gastos catastróficos y empobrecedores en salud en un catalizador de la renovación institucional a través de la reforma que creó el Seguro Popular de Salud (SPS. Presentamos tanto las tendencias de los últimos 15 años sobre la evolución de los gastos catastróficos y emprobrecedores en salud, como las evidencias recientes sobre el mejoramiento en estos indicadores con la expansión del SP. Los resultados de la experiencia mexicana sugieren que la organización y el financiamiento del sistema de salud han jugado un papel muy importante en la reducción del empobrecimiento y en la protección de los hogares durante los periodos de crisis financiera individual y colectiva.Absence of financial protection in health is a recently diagnosed "disease" of health systems.

    Full Text Available La equidad en educación es socialmente deseable debido a la relevancia de la formación en el desarrollo de las personas. Por ello, resulta interesante estudiar si la asignación del gasto destinado a educación tiene en cuenta este aspecto. Dado que el concepto de equidad no es un unívoco, es necesario definir una postura; en el trabajo se asume que existe equidad educativa si hay igualdad en los resultados educativos. Así, el objetivo de éste es analizar si la distribución del gasto educativo entre los distritos de la provincia de Buenos Aires, Argentina, es equitativa. Se planteó la hipótesis de que no lo es. Para contrastarla, se utilizó el coeficiente de GINI y una regresión de Mínimos Cuadrados Ordinarios (MCO. Se halló que la distribución de los fondos se vincula en forma directa con el grado de analfabetismo de los distritos, pero al mismo tiempo se encontró evidencia de que es independiente de la pobreza, de la tasa de abandono escolar, del porcentaje de matrícula en los niveles iniciales y de la proporción de establecimientos clasificados como desfavorables. Entonces, se concluye que la distribución de los fondos de gastos educativos no se rige, o lo hace muy débilmente, por el principio de equidad considerado en el trabajo. Es decir, que la evidencia empírica verifica la hipótesis propuesta.

El estudio se efectuó en condiciones de producción durante tres meses, se realizaron las siguientes mediciones en cada nave: Cantidad de animales y peso de los mismos, tiempo de limpieza, cantidad de agua gastada en la limpieza y residual total (excreta más orine más agua de limpieza. Los animales por naves fueron de: 91,87 y 111 y sus pesos promedio de: 52, 56 y 72 kg. El tiempo empleado en la limpieza fueron de 39, 47 y 55 minutos. La cantidad de agua empleada en la limpieza fue de: 2,28 m3, 2,31 m3 y 2.80 m3 y el residual (incluyendo la excreta más la orine de: 2,55 m3, 2,57 m3 y 3,24 m3. A las medidas anteriores se le realizaron análisis de varianza. La cantidad total de residual de las tres naves fue de 8,36 m3 y el gasto de agua por animal en total fue de 25,51 L. La reducción de los sólidos totales, sólidos volátiles y demanda química de oxigeno fue de 75, 79 y 62% respectivamente, este último resultado es menor que lo obtenido en evaluaciones realizadas a otros biodigestores de cúpula fija. Se aprecia que se gasta mucha agua en la limpieza y por lo tanto se necesita instrumentar sistema de tratamiento de residuales que puedan soportar estos grandes gastos de agua lo que hace que la inversión en el tratamiento del residual se encarezca.

    Full Text Available The aim of the study is to evaluate the friction and wear behavior of high-strength alloys Ti-6Al-7Nb used in femoral stem and compare it with a Ti-6Al-4V alloy cylindrical bar corresponding to ISO 5832-3 part 3/01-07-199 standard. The tribological behavior was investigated by wear tests, using ball-on-disc and pin-on-disc tribometers. These tests consisted of measuring the weight loss and the friction coefficient of samples. The oscillating friction and wear tests have been carried out in ambient with oscillating tribotester in accordance with standards ISO 7148, ASTM G99-95a, and ASTM G133-95 under different conditions of normal loads (3, 6, and 10 N and sliding speeds (1, 15, and 25 mm·s−1. As counter pairs, a 100Cr6 steel ball with 10 mm in diameter was used. Results show that the two alloys had similar friction and wear performance, although their grain structures and compositions are different. Occurrence of large frictional occurred, is probably caused by formation and periodic, localized fracture of a transfer layer. Higher friction with larger fluctuation and higher wear rate was observed at the higher siding speed. The Ti-6Al-4V wear mechanism transforms from ploughing and peeling off wear at low sliding speed to plastic deformation and adhesive wear.

En la segunda parte, se analiza el papel de la seguridad ciudadana en el marco de la Política de Defensa y Seguridad Democrática, la cual es la directriz de la política de seguridad en Colombia. En tercer lugar se examina la composición del gasto en defensa y seguridad en Colombia y la del sector social y de justicia, con la intención de analizar el peso de las medidas de control y prevención en la política pública de seguridad. Finalmente, se presentan algunas conclusiones y sugerencias suscitadas a partir del análisis precedente. ABSTRACT: The objective of this article is to answer the following two questions: is there a clear citizen security policy in Colombia? And, what are the characteristics of the Colombian public expenditure on citizen security? To answer these questions, in the first part the legal and institutional framework of the security policy is presented with an emphasis on those parts which are pertinent to citizen security. In the second part is analyzed the role of the citizen security within the Defense and Democratic Security Policy, which is a guideline of the security policy in Colombia.In third place, the composition of the security and defense budget, as well as those of the justice and social sectors, are considered in order to analyze the role of the control and preventative measures within the security policy. Finally, some conclusions and suggestions based on the previous analysis are presented.

  15. Total fusion cross sections for 18, 17, 16O+27Al at energies near the Coulomb barrier

    International Nuclear Information System (INIS)

    Total fusion cross sections have been measured for 18, 17, 16O+27Al systems at bombarding energies 27-42 MeV. The evaporation residues were detected in the angular range 4deg-25deg(Lab) using a ΔE-E counter telescope. Barrier radii extracted from total fusion and elastic scattering cross sections are found to increase with the projectile mass. The effect of the yrast levels on the isotopic yields in the evaporation cascade is investigated. (author)

    Full Text Available La elaboración y ejecución de las políticas monetarias y fiscales restrictivas en las dos últimas décadas en nuestro país, han afectado el correcto funcionamiento del ICE. Las metas que se plantean las autoridades monetarias y hacendarias año tras año, conllevan a una serie de restricciones en el ámbito presupuestario, limitándose el nivel de gastos corrientes, de inversiones y de endeudamiento de dicha institución. Con el argumento de que el ICE es parte del problema (cuando en realidad ha contribuido ha aminorarlo del desequilibrio en las finanzas públicas, se ha cercenado su autonomía e independencia; sin atacar la verdadera causa de dicho desbalance, tal y como son el déficit del gobierno central y de la autoridad monetaria.A nivel de las finanzas públicas, se incorporan las estadísticas del ICE bajo un formato contable que difiere de manera importante con los principios de la contabilidad que utilizan las empresas del sector privado. Dicha metodología es obsoleta, presentado serias deficiencias que el mismo FMI (quien la elaboró reconoce. Este mismo organismo ya ha elaborado una nueva metodología que aún no se utiliza en nuestro país. Más aún, existen países que utilizan metodologías diferentes, las cuales están mas acordes con la contabilidad tradicional de empresa privada.Los impactos positivos o negativos que la actuación del ICE pueda tener sobre el equilibrio macroeconómico, el crecimiento y el desarrollo del país, es algo aún no medido, cuyas relaciones de causa y efecto no se han establecido de manera real. En el debate y las discusiones, han prevalecido más bien las posturas políticas e ideológicas (en respuesta a intereses particulares, en detrimento del análisis científico y técnico. Así mismo, las discusiones se han fundamentado en postulados teóricos, sin ser contrarrestados contra la realidad.

    Full Text Available Las crisis económicas que han afectado a México desde principios de los años ochenta han influido de manera determinante en el gasto público en bienestar social y, por lo mismo, en el gasto público en salud. En este trabajo se discute la relación que ha existido entre las estrategias de ajuste y el gasto en salud en población no asegurada, así como la distribución de este gasto por regiones. En la primera parte se describe la evolución del gasto público general, el gasto en bienestar social y el gasto público en salud en México entre 1980 y 1995. En la segunda parte se describe con mayor detalle la distribución del gasto público en salud en ese mismo periodo entre la población no asegurada de las cinco regiones en las que dividió al país la Encuesta Nacional de Salud II. La principal conclusión que se desprende de este trabajo es que en el periodo 1980-1995 se mantuvieron las brechas en el gasto en salud para población no asegurada que desde tiempos remotos existen entre las cinco regiones de México. Estas brechas afectan sobre todo a los estados más marginados –que se ubican en su gran mayoría en el sur del país–, no guardan ninguna relación con las diferencias regionales en las condiciones de salud y corren el riesgo no sólo de mantenerse sino incluso de profundizarse como resultado de los nuevos recortes relativos del gasto en bienestar social que contempla la política de ajuste adoptada por la presente administración.In the last fifteen years Mexico suffered several economic crisis which have negatively affected public expenditure in social welfare and, as a consequence, public expenditure in health. This paper discusses the relationship between the adjustment policies adopted to confront these crisis and public expenditure in health care for the non-insured population, as well as the regional distribution of this expenditure.

Se establecieron para ello diversas fronteras de producción, construidas a partir de los mejores resultados dentro de grupos de municipalidades y luego se estimó la eficiencia relativa como la distancia a dichas fronteras. Se utilizaron cinco metodologías para la estimación de las fronteras de producción: (i 3 no paramétricas (Free Disposal Hull, FDH, y Data Envelopment Analysis, DEA-CRS yDEA-VRS y (ii dos paramétricas (una determinística y otra estocástica, las cuales se estimaron a través de las diez categorías de municipalidades (cuatro provinciales y seis distritales definidas mediante una metodología de conglomerados. Finalmente, a partir del empleo de modelos de regresión de tipo TOBIT, se analizaron los determinantes fiscales, socioeconómicos y demográficos de los niveles de eficiencia encontrados. Los resultados obtenidos son diversos y varían según la categoría del municipio analizado; a pesar que fue posible identificar algunas buenas prácticas municipales, los resultados a nivel nacional son preocupantes puesto que indican que se podría alcanzar la misma provisión de bienes y servicios municipales con 57,6% menos recursos. Entre los principales determinantes de este gasto ineficiente se encontraron las transferencias de los recursos del FONCOMUN y del canon, sobre todo a nivel distrital, mientras que uno de los factores que permitió una provisión más eficiente de los servicios públicos locales fue la participación ciudadana, aproximada por la presencia de los Consejos de Coordinación Local.

    Recent advances in pharmacology, diagnostic and invasive procedures provide a series of modalities that diminish the morbidity and increase the long term survival in the patients that have suffered a heart attack to myocardium. The stratification by risk is an essential element for the handling of the survivors of heart attack to myocardium. In their attention it is looked for to optimize the therapeutic benefit, to diminish the unnecessary diagnostic and therapeutic procedures and to improve the efficiency. For example, a coronariography in sick with heart attack to myocardium it is not cost-effective if not is clinically suitable. Of there that from the institutional point of view, this is, of the Mexican Institute of the Public Health, they are required of appropriate reference approaches and counter reference to grant to the sick person, the best service that is the one in this case the diagnostic and the handling of the ischemic cardiopathy with the smallest waste of resources. The estimation of the annual survival is the base of the stratification, it constitutes the angular stone of the early handling of the heart attack to myocardium. The goal for the clinical would be to identify patients with intermediate risk, since, this risk makes them candidates to therapy interventionist. As long as those with low risk won't require intervention. This would allow the decrease of rates by revenues of heart attack to myocardium, and therefore to diminish the hospital staying rates. The Nuclear Cardiology (myocardial gammagraphy) it is not the only invasive method available to evaluate the myocardial perfusion in sick in who coronary illness is suspected. When the myocardial gammagraphy is carried out in appropriate population, the cost it diminishes because it restricts the necessity of additional invasive evaluations. This because the nuclear cardiology has predictive value so much for the mortality like to detect myocardial viability. Based on these probabilities, the doctor it could recommend diagnostic tests more sensitive and by this more cost-effective. The goal of this study was to design a model that compared cost-effectiveness of the gammagraphy in the diagnosis of the coronary illness by means of computed tomography by emission of simple protons (SPECT).

MÉTODOS: Pareamento probabilístico-determinístico a partir das bases das Autorizações de Procedimentos de Alta Complexidade com o Sistema de Informação sobre Mortalidade, resultando em coorte histórica de pacientes que utilizaram medicamentos de alto custo para o tratamento da osteoporose na pós-menopausa de 2000 a 2006. O gasto médio mensal com medicamentos foi estratificado por faixas etárias e descrito de acordo com as características demográficas, clínicas e tipo de medicamento utilizado. Foi utilizado modelo de regressão linear para avaliar o impacto de características demográficas e clínicas sobre o gasto médio mensal per capita com os medicamentos. RESULTADOS: Foram identificadas 72.265 mulheres que receberam medicamentos para o tratamento da osteoporose na pós-menopausa. O gasto médio mensal per capita no primeiro ano de tratamento foi de R$ 90,00 (dp R$ 144,49. A maioria das mulheres tinha de 60 a 69 anos de idade, iniciaram tratamento em 2000, eram residentes na região Sudeste, tinham fraturas osteoporóticas prévias e o alendronato de sódio foi o medicamento mais utilizado no início do tratamento. A maioria das pacientes permaneceu em uso do mesmo princípio ativo durante o tratamento. Foram identificados 6.429 óbitos entre as participantes. Mais de um terço das mulheres permaneceram no programa por até 12 meses. Raloxifeno e calcitonina sintética foram as alternativas com maior impacto sobre o gasto médio mensal com medicamentos, tendo como padrão de referência o alendronato de sódio. CONCLUSÕES: Dado o alto impacto do tipo de medicamento utilizado no gasto com medicação, recomenda-se estabelecer critérios para prescrição e dispensação, com prioridade para aqueles com menores custos e maior efetividade. Isso pode otimizar o processo de assist

La línea argumental del texto es que, pese a la dureza de la crisis (doble recesión, el gasto social en España no se ha hundido (en su peso en producto interior bruto y per cápita, dada la evolución de estos referentes, aunque sí padece evidentes restricciones en términos de beneficiarios. En el ámbito de la salud, la situación se mantiene gracias al esfuerzo de muchos –el pool de renta de las familias en general y de los profesionales sanitarios en particular–, de modo que se ha conseguido que las prestaciones sanitarias no se deterioren (al menos como lo han hecho la ocupación privada y el conjunto de las finanzas públicas. El equilibrio es, sin embargo, muy frágil y sólo recuperando el crecimiento se atisba un estado de bienestar mínimamente sostenible. En cualquier caso, si la sostenibilidad financiera la referimos al agregado de los recursos disponibles para nuestro sistema sanitario, resulta igualmente ineludible replantearse su composición de modo más acorde con la realidad social y con el nuevo binomio entre responsabilidades públicas y privadas que exige el desarrollo social del siglo xxi.

    Full Text Available Al contrario de lo que señala parte importante de la teoría, el gasto de campaña tiene un efecto significativo sobre el éxito electoral de los incumbentes en la elección de diputados de 2005 en Chile. Más aún, los rendimientos electorales del gasto son mayores para los candidatos con más de un período en el cargo. El gasto de campaña parece no sólo sumarse a las "ventajas" de los incumbentes, sino multiplicar su efecto sobre el rendimiento electoral. En segundo lugar, se aprecia que los incumbentes que ganaron en 2001 por mayores márgenes dentro de su pacto tienden a mostrar -contrario a lo esperable- mayor gasto de campaña. Por un lado, este hecho va en línea con la idea de que los candidatos tienden a percibir que su gasto multiplica sus cualidades y no parece presentar rendimientos marginales decrecientes. Este comportamiento también se ve reforzado por la lógica del financiamiento público de campañas, que reembolsa dinero de acuerdo a la votación obtenida y hace que, como sugiere la teoría, la decisión de gasto esté influida por las expectativas de obtener un mayor subsidio.Contrary to what an important part of the theory says campaign expenditure has a significant effect on the electoral success of incumbents in the House of Representatives elections of 2005 in Chile. Moreover, electoral performance of expenditure is greater for those candidates with more than one period in office. Campaign expenditure not only adds to the "incumbency advantages" of incumbents, but also multiplies their effect on electoral performance. Secondly, it is assessed that incumbents who won in 2001 by greater margins in their coalition tend to show greater campaign expenditures (contrary to what was expected. On one hand, this fact is coherent with the idea that candidates tend to perceive that their expenses multiply their qualities and do not present diminishing returns. This behavior is also reinforced by rationale of the public campaign

A Emenda Constitucional nº 19 de 1999 introduz o princípio da eficiência à lista de princípios constitucionais da Administração Pública. Nesse sentido, o presente estudo objetiva analisar a eficiência dos gastos municipais em educação no ensino fundamental, no contexto dos municípios do Seridó Potiguar, RN. Para tanto, e de acordo com o objetivo definido, pode ser caracterizado como quantitativo e descritivo, fazendo o uso de dados secundários (indicadores educacionais com vistas a propor índices de performance da eficiência educacional. A região de estudo escolhida contempla 21 municípios. Os resultados evidenciaram três rankings de eficiência, tendo o município de Carnaúba dos Dantas atingido a melhor eficiência nos três e os municípios de Parelhas e São João do Sabugi revezam entre a segunda e a terceira posição. O Índice de Eficiência Total do Gasto com Educação (IETGE revelou que o município com pior eficiência foi Santana do Matos. Observou-se que oito municípios apresentaram IETGE baixo, significando que boa parte dos municípios analisados não teve um desempenho proporcional aos gastos aplicados. Também se evidenciou uma considerável diferença entre os municípios quanto à eficiência de gastos com educação. O trabalho evidencia a possibilidade e a importância de mensurar eficiência no setor público, bem como proporciona a construção de rankings nesse setor como instrumento propulsor do aumento da eficiência na área pública. Sugere-se realizar uma pesquisa em profundidade nos municípios de maior e menor indicador para compreender que dimensões/fatores conduzem para o êxito ou fracasso nos índices, bem como replicar o modelo em outras regiões geográficas.

Por tipo de cuidados médicos, los servicios preventivos se han desarrollado más que los servicios hospitalarios y curativos. Los resultados sostienen la hipótesis de que la universalización de los servicios de salud y su unificación en una sola entidad proveedora mejoraría sustancialmente la equidad del sistema de salud pública en México.

  19. Nível e evolução da desigualdade dos gastos familiares no Brasil: uma análise para as regiões metropolitanas no período 1996 a 2003

    Full Text Available A partir da utilização dos microdados da Pesquisa de Orçamento Familiar (POF dos biênios 1995-96 e 2002-03, o trabalho fornece evidências a respeito dos níveis e da evolução da desigualdade da distribuição dos gastos familiares per capita e da desigualdade da distribuição do consumo familiar per capita no Brasil metropolitano e a respeito da importância dos diferentes tipos de gastos familiares nas dinâmicas observadas. Os resultados, obtidos a partir de indicadores tradicionais de desigualdade e de análises de Dominância de Lorenz, apontam para importantes movimentos em termos de diminuição da desigualdade em ambos os tipos de gastos. Medida a desigualdade pelo índice de Gini, observa-se que a redução deste índice é afetada de forma significativa pelas dinâmicas dos gastos com Habitação, Higiene e Cuidados Pessoais e Vestuário, favoráveis à diminuição da desigualdade, e pelas as dinâmicas dos gastos com Educação, Saúde e Alimentação, favoráveis à desigualdade. Diferenças regionais são apontadas a partir das regiões metropolitanas de Recife e São Paulo.By using micro data from the Pesquisa de Orçamento Familiar (POF for years of 1995-96 and 2002-03, the paper presents evidence about the evolution of the inequality levels for per capita familiar spending and per capita familiar consumption distributions in Brazil metropolitan regions. The results, obtained by using traditional inequality indicators and Lorenz Dominance, show that the dynamics of inequality for these distributions present important movements favoring inequality reduction. Spending dynamic of Habitation, Hygiene and Personal Care and of Wearing favored total consumption inequality and the dynamic spending of Education, Health and Food favored total consumption inequality increasing. Regional differences are highlighted by considering the cases of Recife and São Paulo metropolitan regions.

  20. SiC nanoparticle-reinforced Al2O3-Nb composite as a potential femoral head material in total hip arthroplasty

    International Nuclear Information System (INIS)

    A ceramic-metal composite consisting of SiC nanoparticle-reinforced Al2O3 and Nb (referred to as SiC/Al2O3-Nb), was prepared and evaluated in vitro for potential application as a femoral head material in total hip arthroplasty. Dense bi-layer laminates of SiC nanoparticle-reinforced Al2O3 and Nb were fabricated by hot pressing of powders (1425 deg. C; 35 MPa), and evaluated using scanning electron microscopy, microchemical analysis, and mechanical testing. The flexural strength of the SiC/Al2O3-Nb laminate (960 ± 20 MPa) was higher than the value (720 ± 40 MPa) for an Al2O3-Nb laminate, and far higher than the value (620 ± 50 MPa) for SiC nanoparticle-reinforced Al2O3 (SiC/Al2O3). The Vickers hardness of SiC/Al2O3 was 17 ± 2 GPa, compared to 12 ± 1 GPa for Al2O3. A high interfacial shear strength of the SiC/Al2O3-Nb laminate (310 ± 100 MPa), coupled with SEM observation of the interfacial region, showed strong bonding between the SiC/Al2O3 and Nb layers. Composite femoral heads consisting of a SiC/Al2O3 surface layer and a Nb core could potentially lead to a reduction in the tendency for brittle failure as well as to lower wear, when compared to Al2O3 femoral heads.

    Full Text Available People's energy requirements are related to their energy expenditure (EE; this is defined as being the energy which an organism consumes. It is represented by the basal metabolic rate (BMR, physical activity (PA and dietinduced thermogenesis (DIT. The BMR is the minimum amount of energy which an organism requires to stay alive and represents 60%-70% of total energy expenditure (TEE in most sedentary adults. The PA represents 25%- 75% of TEE whilst DIT represents around 10% of TEE. Anthropometry is the method most frequently used in studying body composition due to its simplicity, low cost and great precision.El requerimiento de energía de una persona está relacionado con su gasto energético (GE y se define como la energía que consume un organismo, está representado por la tasa metabólica basal (TMB, la actividad física (AF y la termogénesis inducida por la dieta (TID.

También podría ser de interés para médicos de atención primaria, especialistas y autoridades sanitarias de Cuenca y de otras áreas de salud, y para investigadores en gestión sanitaria y economía de la salud. Métodos: Se desarrolla un análisis de regresión lineal múltiple para tres variables dependientes con el fin de conocer qué características permiten explicar la variabilidad en la prescripción de genéricos, la tasa de derivación y el gasto farmacéutico de los médicos de atención primaria. Resultados: No ser médico interno residente (MIR, ejercer en un municipio de más de 10.000 habitantes y con un cupo de gran tamaño, supuso un impacto negativo en el porcentaje de medicamentos genéricos prescritos. Los médicos que usan la historia clínica informatizada y derivan más a especializada, prescriben menos genéricos. Las dos variables más importantes para explicar el elevado gasto farmacéutico son el mayor tamaño del cupo y el alto porcentaje de pacientes mayores de 65 años. El mayor número de genéricos reducía el gasto, y el incremento en el porcentaje de pacientes mayores en el cupo lo aumentaba. Conclusiones: Una de las variables que mejor explica el gasto farmacéutico es el porcentaje de genéricos prescritos, teniendo en cuenta que se controla por variables tan importantes como tamaño del cupo o porcentaje de pacientes de edad avanzada incluidos en él.Objective: To determine the factors related to pharmaceutical expenditure per primary care physician in the province of Cuenca, which could allow public health authorities to take decisions to curb expenditure.

  16. Co-Mg-Al oxides issued of hydrotalcite precursors for total oxidation of volatile organic compounds. Identification and toxicological impact of the by-products

    International Nuclear Information System (INIS)

    Catalysts based on Co-Mg-Al, which were used for the total oxidation of toluene, were synthesized by using the hydrotalcite pathway. The calcination allowed us to obtain various mixed oxide types (i.e. Co3O4, Co2AlO4 or CoAl2O4), presenting meso-pores of about 8 nm and high specific surface areas. The solids were tested for the total oxidation of toluene and showed a total selectivity in CO2 and H2O for 100% of toluene conversion. However, studies using diffuse reflectance infrared 'operando' and GC-MS allowed us to identify intermediary by-products stemming from the catalytic oxidation of toluene: benzene and small quantities of benzaldehyde, styrene and acetophenone. In order to contribute to the improvement of the current scientific knowledge on volatile organic compound (VOC) toxicity in humans, the lung toxicity of toluene, benzene or their association was determined by using a human epithelial lung cell model (i.e. L132 cell line). VOC cytotoxicity was studied with three complementary methods: the enzymatic activity of extracellular lactate dehydrogenase (LDH), the enzymatic activity of mitochondrial dehydrogenase (mDH), and the incorporation of 5-Bromodeoxyuridine (5-BrdU). Taken together, these results showed the occurrence of adverse effects, notably reported by significant increases in LDH activity in cell culture supernatants, 24 hours after L132 cell exposure not only to toluene alone or benzene alone, but also to their association. This original approach allowed us to integrate some toxicological parameters to help the choice of new-dedicated catalysts for the oxidative conversion of VOC. (authors)

    A series of Pd/La-Al2O3 (PLA) catalysts with La-Al2O3 (LA) support calcined at different temperatures (500, 700, 900 and 1050 ºC) were prepared using an incipient wetness impregnation method. The activity of the fresh and hydrothermally aged PLA catalysts were tested for total oxidation of CO and C3H8. The activity of the fresh PLA catalysts for CO and C3H8 oxidation increased with increasing calcination temperature of the support, while the activities of the aged catalysts declined and became essentially the same. CO chemisorption results revealed that the suppressed activities of the aged catalysts were mainly due to the decline of palla-dium dispersion. The turnover frequency (TOF) of CO oxidation increased with increasing reduction ability of the catalysts, with a fresh catalyst calcined at 1050 ºC having the highest value (0.048 s-1). However, the TOF of C3H8 total oxidation was affected by not only the redox properties of catalysts but also the size of Pd particle, and large Pd particles possessed higher TOF value of C3H8 oxi-dation, with the highest value (0.125 s-1) being obtained on an aged catalyst calcined at 500 ºC.

    Full Text Available O objetivo deste artigo é analisar o debate entre arrecadação e gastos públicos governamentais para o caso brasileiro, isto é, se a despesa pública é a responsável por gerar constantes aumentos da arrecadação governamental brasileira, ou se a causalidade é reversa. A metodologia econométrica utilizada envolve técnicas de cointegração e de modelo de correção de erros para o período compreendido entre o 1o trimestre de 1999 e o 3o trimestre de 2008. Os resultados econométricos mostram que, no período analisado, o Estado brasileiro pode ser caracterizado pela utilização de um modelo fiscal do tipo "gastar e arrecadar". Isso significa que elevações nos dispêndios governamentais provocam mudanças permanentes na arrecadação pública.The aim of this paper is to analyze the tax-spend debate for the Brazilian case, that is, if an increase in public spending leads to an increase in government revenues, or if there is a reverse causality (the increase in government revenues leading to an increase in public spending.

The results show that the Brazilian government follows a "spend and tax" policy. It means that more government spending leads to permanently higher taxes.

  11. An In-Situ XAS Study of the Structural Changes in a CuO-CeO2/Al2O3 Catalyst during Total Oxidation of Propane

    International Nuclear Information System (INIS)

    A CuOx-CeOx/Al2O3 catalyst was studied with in-situ transmission Cu K XAS for the total oxidation of propane as model reaction for the catalytic elimination of volatile organic compounds. The local Cu structure was determined for the catalyst as such, after pre-oxidation and after reduction with propane. The catalyst as such has a local CuO structure. No structural effect was observed upon heating in He up to 600 deg. C or after pre-oxidation at 150 deg. C. A full reduction of the Cu2+ towards metallic Cu0 occurred, when propane was fed to the catalyst. The change in local Cu structure during propane reduction was followed with a time resolution of 1 min. The χ(k) scans appeared as linear combinations of start and end spectra, CuO and Cu structure, respectively. However, careful examination of the XANES edge spectra indicates the presence of a small amount of additional Cu1+ species

El interés por el estudio de la defensa y la seguridad es reciente y ha cobrado auge debido a la inserción de Colombia en el escenario internacional, a causa del conflicto interno que persiste en el país, y que ha llegado a ser parte de la agenda internacional. El sector defensa no ha tenido tradición tecnocrática, y el campo de investigación es incipiente, el presente trabajo presenta una aproximación al estudio del gasto en defensa y seguridad (GDS entre 1950 – 2006, donde se comprobará como éste agregado macroeconómico se mantuvo por debajo del promedio regional a través del siglo XX.  El GDS de este país no se correlaciona con el conflicto interno y la trayectoria que sigue es aleatoria; la política de seguridad y defensa es producto de eventos coyunturales y no el fruto de una planificación del primer bien público que debe entregar un Estado a sus ciudadanos, de esta forma la inferencia que este ha tenido sobre hacienda pública, no responde a una política pública estatal.   Abstract The present investigation centers its analysis in the cost of defense and security (GDS using the use of the discipline of the defense economy, which studies the policies of security by means of the application of tools elaborated by the economy as they are the methods of macroeconomic and microeconomic analysis, static optimization - dynamic, theory of games and Econometry.

Trinta indivíduos (16 homens de 22,7 ± 2,6 anos e 14 mulheres de 22,1 ± 2,1 anos, não-atletas, alunos do curso de Educação Física, foram instruídos a caminhar na esteira ergométrica com 1% de inclinação, nas intensidades leve, moderada e alta, em velocidades auto-selecionadas, durante 6 min em cada intensidade. O VO2, medido pelo analisador metabólico Teem 100 da Aerosport, a FC e o GEC estimado pelo monitor eram registrados nos 2 últimos minutos de cada carga. Concluiu-se que a melhor predição é feita com a utilização da velocidade de caminhada e com o peso do indivíduo. A FC para predição do GEC deve ser acompanhada do gênero e FC de repouso do indivíduo. A escala proposta no estudo para percepção de intensidade do esforço deve ser utilizada quando não for possível registrar nem a velocidade de caminhada nem a FC do indivíduo. Devem ser tentados outros estudos com outras escalas de percepção do esforço. O monitor de FC Polar M71 é valido para a estimativa do GEC, com as ressalvas de que é necessário que FC ultrapasse 100bpm.

Se establecieron como mejores condiciones para su extracción y para determinación de la actividad: buffer fosfatos 100mM pH 7, 1% SDS y 1% PVPP; sustrato guayacol 15mM, peróxido de hidrógeno 10mM, pH 6,5, 55 °C y 30 µL de extracto. Se realizó un ensayo in vivo usando frutos verdes, pintones y maduros, inoculados con el hongo ó con agua estéril. Se determinó la actividad peroxidasa a diferentes horas a partir de la inoculación encontrándose una respuesta diferencial con el tiempo por efecto de la presencia del patógeno y, según el estado de madurez de los frutos. En lulos verdes inoculados con el hongo se observó aumento en la actividad al cabo de 6 y 144 horas. En lulos pintones no se observó efecto notable, mientras que en maduros el aumento en actividad fue prácticamente a todos los tiempos. Los resultados del contenido de fenoles totales mostraron que hubo acumulación a 96 y 144 horas por efecto del patógeno, para lulos en estado verde y maduro, mientras que para pintones, en los que se presentaron más rápido y con mayor severidad los síntomas de la antracnosis, no se observó aumento a ninguno de los tiempos. En los frutos más enfermos, el cambio en actividad peroxidasa y contenido total de fenoles fue menos evidente por lo que se sugiere una relación inversa de éstos con el desarrollo de la antracnosis.

    Full Text Available In this article, we examine the redistributive nature of public educational spending through a cross-country analysis from 1960 to 1996. Existing studies on the determinants of the extent of public funding of education tend to give for granted its progressive nature. We question this view and, assuming that the redistributive nature of public education is conditional on how expenditure is allocated between the different levels of schooling, we provide evidence on the role of the ideological nature of the party in government and of the economic position of the median voter on the configuration of this policy.

    En este trabajo se discute y analiza la dimensión redistributiva del gasto público en educación mediante un examen comparado de una amplia muestra de países desarrollados entre 1960 y 1996. Los estudios existentes que examinan los determinantes de la financiación pública de la educación suelen suponer que ésta tiene un carácter progresivo. En nuestro análisis se cuestiona esta visión y, partiendo del supuesto de que es la composición del gasto entre los distintos niveles de enseñanza, y no el nivel de gasto total, lo que realmente tiene consecuencias distributivas, se aporta evidencia sobre el peso de la ideología del partido en el gobierno y la posición económica del votante mediano en la configuración de esta política.

Considerando o impacto financeiro que essa condição de saúde gera, foram analisados os gastos de 41 famílias. OBJETIVO: Identificar a estrutura de gasto e receita das famílias responsáveis pelo cuidado de pacientes portadores desta condição. MÉTODOS: Trata-se de um estudo de avaliação de gastos e se caracteriza por ser exploratório, descritivo e transversal. Seu objeto envolve a unidade familiar na qual o doente se insere e os gastos relacionados ao cuidado com o idoso que tem síndrome demencial. O questionário foi aplicado a um grupo de 41 pacientes e suas famílias acompanhados no ambulatório de neurogeriatria da Universidade Aberta da Terceira Idade/Universidade do Estado do Rio de Janeiro (UnATI/UERJ.

  8. Synthesis and physicochemical characterizations of nanostructured Pt/Al2O3-CeO2 catalysts for total oxidation of VOCs

    International Nuclear Information System (INIS)

    Pt/Al2O3-CeO2 nanocatalysts with Pt loading of 1% and ceria loading of 10, 20 and 30% were successfully prepared via wet impregnation method to be utilized in catalytic oxidation of BTX. The nanocatalysts were characterized using XRD, FESEM, TEM, N2 adsorption, FTIR and TPR-H2 techniques. The XRD patterns confirmed the formation of cerium oxide as the crystalline phase on alumina with the average crystallite size of 8.1-8.7 nm, derived by Scherrer equation. FESEM images confirmed that these nanocatalysts had ceria particles in nano-ranges. TEM analysis showed that platinum particles were fairly well dispersed on Al2O3-CeO2 with an average size of 5-20 nm. BET surface area presented large surface area for nanocatalysts. TPR patterns showed that by adding 1% platinum to support, the reducibility is highly increased. These patterns also revealed the promoting effect of ceria on reducibility of Pt and Al2O3. The results of toluene oxidation indicated that the synthesized nanocatalysts were highly active and able to remove nearly 100% of toluene and xylene and about 85% of benzene as representative VOCs. The presence of nanoparticles along with good characteristics of the synthesized nanocatalysts presented them as highly efficient materials for catalytic oxidation of VOCs.

    Full Text Available Este artigo contrapõe a evolução recente do gasto no Brasil: redução do gasto com infra-estrutura social e aumento das transferências monetárias sujeitas à comprovação de renda. Evidencia-se que o modelo de combate à pobreza vigente no Brasil concentrado em programas focalizados de transferência de renda sem promover em simultâneo o aumento do gasto per capita em educação, saneamento básico, habitação não equaciona a questão da desigualdade. Neste artigo, trabalhamos com dados secundários da PNAD e do orçamento da União, estados e municípios.This paper compares the dynamics of social spending in Brazil, with lower outlays on basic services and more direct monetary transfers through means-test programs, highlighting the fact that as Brazil's social safety net concentrates on cash transfer programs without simultaneously increasing per capita outlays on education, basic sanitation and housing, it is not resolving the issue of inequality. This paper works with secondary data from the National Household Sampling Survey, together with Federal, State and Municipal budgets.

Considero a análise de Kemfert, Lise e Tol (2004 como exemplo de modelo formal que agrega as questões econômicas e climáticas, e amplio a discussão com o estudo da inserção dos gastos públicos com gestão ambiental e da matriz energética. Mostro que as estruturas econômicas e físicas dos países estabelecem diferentes gastos públicos, com diferentes impactos ambientais e conseqüências para outras nações e isto afeta sobremaneira os resultados de qualquer modelo econômico. Em termos dos gastos públicos com meio ambiente, observo especificamente o caso brasileiro, verificando os gastos públicos federais com Gestão Ambiental no Brasil de 2000 a 2006. Defendo a importância de se considerar as diversas possibilidades de despesas públicas com gestão ambiental, para o tratamento das questões relativas à mudança climática.In this paper, I, mainly, analyzed the inclusion of environmental budget in climate change models. Considering Kemfert, Lise and Tol (2004's approach to show a formal model that puts together economic and climate issues, I analyzed the inclusion of environmental public spending and energy. I tried to show that countries' economic and physical structures establish different public spending, with different environmental impacts and consequences to another nations and that has strong influence on economic models. In relation to public spending, I considered, specifically, the Brazilian federal budget to Environmental Management from 2000 to 2006. In this article, I argue in defense of considering budget for environmental management in the discussion on climate change.

    2008-02-01

    Full Text Available O conhecimento do gasto energético de repouso é de fundamental importância na determinação das necessidades energéticas e, conseqüentemente, no estabelecimento das recomendações de energia de um indivíduo. O elevado gasto energético, se não compensado por uma ingestão alimentar suficiente, poderá contribuir para a desnutrição e o maior risco de morbidade e mortalidade. Nos pacientes com doença renal crônica, a uremia per se e o tratamento de diálise estão, freqüentemente, associados a vários distúrbios, como a acidose metabólica, a resistência insulínica, o hiperparatireoidismo secundário e a inflamação, que podem aumentar o catabolismo protéico e, em parte, contribuir para o aumento do gasto energético de repouso. A presente revisão tem como objetivo descrever os estudos sobre o gasto energético de repouso nos pacientes com doença renal crônica e os aspectos que influenciam o gasto energético nesta população.Knowledge of resting energy expenditure is of paramount importance for the determination of energy requirements and consequently for the establishment of energy recommendations of an individual. Elevated energy expenditure, if not supplied by enough food consumption, may contribute to malnutrition and higher risk of morbidity and mortality. In patients with chronic kidney disease, uremia per se and the dialysis treatment are frequently associated with several disturbances, such as metabolic acidosis, insulin resistance, secondary hyperparathyroidism and inflammation, that might in part contribute to the increase in resting energy expenditure. The present review aims to describe the studies on resting energy expenditure in patients with chronic kidney disease and the factors influencing energy expenditure in this population.

    2012-07-30

    A series of Pt/Al(2)O(3) catalysts with various tungsten oxide loadings were prepared by a stepwise wet impregnation method. The catalysts were characterized by X-ray diffraction, nitrogen physisorption, Raman, UV-vis diffuse reflectance, transmission electron microscopy and infrared spectroscopy of adsorbed probe molecules (CO, NH(3) or C(3)H(8)). The propane oxidation activity of Pt/Al(2)O(3) catalyst is significantly improved by the addition of tungsten oxide. The tungsten oxide overlayer is presented as monomeric/polymeric WO(x) clusters and WO(3) crystals depending on the loading amount. The most active catalyst occurs at an intermediate surface tungsten density corresponding to the maximum of polytungstate species. The electronic interactions between Pt and WO(x) clusters lead to the generation of more reducible Pt(δ+) species which are suggested to be active sites for propane oxidation. Basically, a simple model is proposed involving the initial CH bond activation at the platinum-tungsten oxide interface. PMID:22609394

    In this study, for a step-like GaAs- Ga_{1-x}AlxAs asymmetric quantum well (AQW) the linear and total intersubband optical absorption coefficients and the refractive index changes are calculated as dependent on the intense laser field (ILF) and the right quantum well (RQW) width. Our results show that the location and the magnitude of all absorption coefficients and refractive index changes depend on ILF and the asymmetric parameter ( d=LR/LL). Also, we showed that both ILF and d provide an important effect on the electronic and optical properties of step-like quantum well, and the changes of the energy levels, the dipole moment matrix elements and the resonant peak values of the absorption coefficients are dependent on the shape of the confinement potential. While for different asymmetric parameters the intersubband absorption spectrum shows blue shift up to the different critical ILF values, this spectrum shows red shift for ILF values greater than certain values. By considering the variation of the energy difference as dependent on the RQW width, for step-like QW the absorption spectrum shows blue or red shift. Especially, step-like QWs are used for producing terahertz radiation from intersubband transitions and they have more tunable structure parameters (the left (right) quantum well width, LL(LR), and the confinement potential in the left (right) hand side, VL (VR) with respect to other asymmetric QWs (in the present study we used LR=LL/2, LL, 3 L L/2 and V R = 2 V L/3 values). This case provides a new degree of freedom for controlling the optical properties in quantum wells (QWs). In addition, the nonlinear optics underlying the application of the ILF to asymmetric potential heterostructures becomes a subject of present-day interest. In conclusion: i) The electronic and optical properties of the step-like AQW vary by increasing ILF. ii) ILF leads to major modifications on the shape of the confining potential. iii) The position and the size of all absorption

    Full Text Available Can federal-state relations affect popular protests? Using an extensive dataset measuring local protests in the Argentine provinces (2002–2006, I assess the effects of the president’s and governors’ tactical allocations on the persistence of contentious events. I analyze how the delivery of federal resources, to both provincial governments and local social organizations, affects the chances of protests occurrence and the nature of its demands. Results show that federal spending increases the frequency of protests in the Argentine provinces, particularly when provincial governments are not involved in its delivery. In addition, protest demands are sensitive to president’s discretional expenditure, suggesting a different dynamics in which protests became a legitimate channel to obtain federal monies.¿Las relaciones entre el presidente y los gobiernos subnacionales podrían influir en la protesta social? Usando una exhaustiva base de datos sobre protesta en provincias argentinas (2002-2006, analizo los efectos que las distintas estrategias de distribución de recursos de los gobernadores y del presidente tienen en la persistencia de los eventos contenciosos. En particular, estudio cómo la distribución de recursos federales, tanto a gobiernos provinciales como a organizaciones sociales locales, afecta las probabilidades de que surjan protestas y la naturaleza de sus demandas. Los resultados muestran que el gasto federal aumenta la frecuencia de las protestas en las provincias argentinas, en particular, cuando los gobiernos provinciales no intervienen en su asignación. También que las demandas de las protestas son sensibles al gasto discrecional del presidente, sugiriendo una dinámica particular en la cual la protesta se convierte en un canal legítimo para obtener fondos federales.

    The surface films formed on commercial LiNi0.8Co0.15Al0.05O2 cathodes (ATD Gen2) charged from 3.75V to 4.2V vs. Li/Li+ in EC:DEC - 1M LiPF6 were analyzed using ex-situ Fourier transform infrared spectroscopy (FTIR) with the attenuated total reflection (ATR) technique. A surface layer of Li2CO3 is present on the virgin cathode, probably from reaction of the active material with air during the cathode preparation procedure. The Li2CO3 layer disappeared even after soaking in the electrolyte, indicating that the layer dissolved into the electrolyte possibly even before potential cycling of the electrode. IR features only from the binder (PVdF) and a trace of polyamide from the Al current collector were observed on the surfaces of cathodes charged to below 4.2 V, i.e., no surface species from electrolyte oxidation. Some new IR features were, however, found on the cathode charged to 4.2 V and higher. An electrolyte oxidation product was observed that appeared to contain dicarbonyl anhydride and (poly)ester functionalities. The reaction appears to be an indirect electrochemical oxidation with overcharging (removal of > 0.6 Li ions) destabilizing oxygen in the oxide lattice resulting in oxygen transfer to the solvent molecules.

    Full Text Available Programas de transferência condicionada de renda são políticas sociais correntemente empregadas para combater e reduzir a pobreza em diversos países. No curto prazo, esses programas visam aliviar os problemas decorrentes da situação de pobreza, sendo que, no longo prazo, o objetivo é investir no capital humano, quebrando o ciclo intergeracional da pobreza. Estudos têm sido realizados para avaliar os impactos desses programas sobre variáveis como freqüência escolar, trabalho infantil, gastos com alimentação, entre outros. Este trabalho avalia o impacto da transferência de renda do Programa Bolsa Família sobre os gastos com alimentos de famílias rurais. As estimações foram feitas com base no método de Propensity Score Matching (PSM, que corrige para o viés de seleção amostral. Os resultados mostram que o valor médio das despesas anuais para as famílias beneficiárias supera em R$ 246 os gastos totais das famílias não-participantes. Considerando que a média anual recebida por essas famílias é de R$ 278, pode-se inferir que 88% desse valor é utilizado para consumo de alimento. Portanto, o programa de transferência condicionada Bolsa Família exerce um impacto positivo sobre o consumo de alimentos dessas famílias selecionadas.Conditional income transfer programs are social policies currently adopted to reduce poverty in several countries. These conditional transfer schemes have a goal to alleviate some of the consequences of poverty in the short run and increase human capital in the long run changing the intergenerational poverty cycle. Several papers evaluate the impact of income transfer on school attendance, child work and food expenses, among others. This paper analyzes the impact of the Bolsa Família Program on food expenses of rural families. The Propensity Score Method was used to correct sample selection bias. Results show that annual food expenses increased 246 reais in relation to non participant families

MÉTODOS: Participaram do estudo 15 homens bem treinados, com idade de M=24,4, DP=3,70 anos e consumo máximo de oxigênio (VO2max de M=70,00, DP=5,32mL (kg.min-1. Após o consumo das refeições, os participantes permaneceram por noventa minutos no calorímetro indireto Deltatrac®, para a avaliação dos parâmetros metabólicos. A seguir, foi realizado um exercício de 85 a 95% da frequência cardíaca máxima, em três estágios de dez minutos. Os parâmetros metabólicos foram novamente avaliados durante os sessenta minutos pós-exercício. RESULTADOS: Os tratamentos aplicados no estudo não afetaram o gasto energético, o consumo excessivo de oxigênio e a oxidação lipídica após o exercício. Entretanto, a taxa de oxidação de gordura foi maior durante os noventa minutos no grupo que consumiu a refeição de alto índice glicêmico antes do exercício, em relação ao da refeição de baixo índice glicêmico. Além disso, a taxa de oxidação lipídica do período pós-prandial foi inferior àquela obtida no período pós-exercício. CONCLUSÃO: Os resultados sugerem que enquanto o consumo de refeições de baixo índice glicêmico pode não exercer efeito benéfico, a realização de exercício físico pode promover maior oxidação lipídica e consequentemente afetar a redução do teor de gordura corporal.OBJECTIVE: The present study assessed, on 5 consecutive days, the effect of consuming meals with different glycemic indices on energy expenditure, energy substrate oxidation and excessive oxygen consumption after exercise.

    Total bremsstrahlung (BS) spectra in thick targets of Al, Ti, Sn and Pb produced by beta emitter 90Sr (End point energy=546 keV) are studied in the photon energy range of 1-100 keV. The experimentally measured BS spectra are compared with the theoretical spectral distributions calculated from Elwert corrected (non relativistic) Bethe-Heitler [EBH] theory, modified Elwert factor (relativistic) Bethe-Heitler [Fmod BH] theory for ordinary bremsstrahlung (OB) and the Avdonina and Pratt [Fmod BH+PB] theory, which include the contribution of polarization bremsstrahlung (PB) into OB. The present results are indicating the correctness of Fmod BH+PB theory in the low energy region, where PB dominates into the BS, but at the middle and higher photon energy region of the bremsstrahlung spectrum, the Fmod BH theory is more close to the experimental results. The description of the bremsstrahlung process in stripped atom (SA) approximation, which indicates the suppression of the bremsstrahlung at higher energy ends due to the production of PB in the low energy region, needs further considerations. Hence, the present measurements for BS for different target materials indicates that the considerations of the screening effects along with other secondary effects during the interaction of incident electrons with the target nuclei are important while describing the production of bremsstrahlung, particularly for the higher energy regions.

    Full Text Available Research from various countries has shown that incumbents in legislative elections raise and spend more money when they face a tougher contest. A statistical analysis of Chilean candidates’ campaign finance disclosures shows the opposite: an inverse relationship between incumbent spending and electoral competitiveness. This occurs because Chile’s deputies are relatively limited in their influence over policy and pork and because the congressional electoral system makes most competitive contests relevant only to the intra-coalitional balance of power. This account implies that political finance is as much a function of political systems and the supply of contributions as it is candidates’ demand for funds, and motivates several hypotheses about campaign finance in Chile. Among others, the analysis confirms that incumbents and challengers compete on a level playing field, spending similar amounts of campaign finance. The paper also illustrates that incumbents and challengers fare equally well in Chile’s “secret” donation system.Estudios en varios países han demostrado que los incumbentes en las elecciones legislativas recaudan y gastan más dinero cuando se enfrentan a una competencia más dura. No obstante, el análisis estadístico del financiamiento electoral de candidatos chilenos demuestra lo contrario: una relación inversa entre los gastos de los incumbentes y la competitividad electoral. Esto ocurre porque los diputados son relativamente limitados en su influencia sobre políticas públicas e incluso en la dispensa de favores canalizados (pork-barrel y porque el sistema binominal hace que la competencia suceda principalmente al interior de coaliciones. La implicación lógica es que el financiamiento político es tanto una función del sistema político y de la oferta de contribuciones de campaña, como de la demanda de los candidatos por esos fondos, hecho que motiva la presentación de varias hipótesis sobre la financiaci

    Full Text Available La auditoría de contratos o auditoría de costes y precios se aplica por el Ministerio de Defensa español (MINISDEF en aquellos casos en que los precios de los bienes y servicios que se desean adquirir no se determinan en el marco de lo que la doctrina económica considera un entorno de competencia efectiva. En este escenario, el órgano de contratación no dispone de información suficiente, íntegra y fiable que le permita soportar la aprobación de un gasto basado en un precio razonable. Si bien la metodología y los procedimientos de trabajo de la auditoría de costes y precios en España ha sido desarrollada por el Grupo de Evaluación de Costes sobre la base de las normas de The Defense Contract Audit Agency de Estados Unidos (EE.UU., la misma ha evolucionado hasta adquirir unos rasgos propios que caracterizan el modelo actualmente vigente en España. En este contexto, el principal objetivo de este trabajo es analizar la metodología utilizada en la aplicación de la auditoría de costes y precios en España, así como los principales resultados alcanzados en la racionalización del gasto público en defensa. The contract audit or cost and price auditing is applied by the Spanish Ministry of Defense (MINISDEF when prices of goods and services to be acquired are not determined in the framework of what economic theory considers an environment of effective competition. In this scenario, the contracting authority does not have enough information, and it is neither integral nor reliable to support the decision to take an expenditure based on a reasonable price.

    Full Text Available Durante la segunda mitad del siglo XVIII, la Corona española se embarcará en un ambicioso programa de reformas. Se tratará de fortalecer el papel del Estado, de recuperar espacios de poder, algo especialmente necesario en las colonias, donde el control metropolitano se diluía a manos de unas oligarquías cada vez más poderosas. Sin embargo, lo que hubiera debido ser una ofensiva gubernamental en toda regla, en determinados rincones de la Monarquía quedó muy matizada. Las guerras constantes dibujarán un nuevo paisaje donde aplicar la nueva política colonial, sobre todo en las llamadas plazas fuertes del imperio. Allí, en lugares como Puerto Rico, en un contexto de militarización ascendente y ante unos gastos que amenazaban con arruinar la Hacienda del rey, el papel del Estado quedará cada vez más en precario, cada vez más a merced de unos súbditos que eran los únicos capaces de sostenerlo.

Tony Blair aseguró que su gobierno convertiría la educación en un asunto prioritario. La primera parte del estudio evalúa el grado de gasto educativo en comparación con el resto de la economía. Después de un descenso en el porcentaje de los ingresos nacionales dedicados a educación en los años previos al 2000, que obedecía a los planes de gasto anteriores de los conservadores, se produjo un incremento significativo del gasto. La segunda parte del estudio analiza el impacto del cambio de incentivos que las escuelas han experimentado en cuanto a los resultados escolares. Entre estos cambios hay la introducción de un plan de estudios nacional, el examen regular de los alumnos, la publicación de los resultados de estos exámenes por escuelas, la devolución a las escuelas de parte de los presupuestos y la flexibilización de la elección de escuela por parte de los padres, y la asignación de fondos en función de los alumnos como base de la financiación escolar. Todo eso ha llevado la escuela, en efecto, a una situación de quasi mercado. La tercera parte del estudio analiza la financiación de la educación superior. Después de corregir los fracasos iniciales de diseño de los programas, el nuevo patrón de financiación universitario en Inglaterra se ha convertido en un modelo único en Europa. El estudiante devuelve los créditos que haya utilizado para pagar las tasas y cubrir sus gastos cuando se ha licenciado, en función de los ingresos y mediante la declaración de renta.

  6. Cataracts following bone marrow transplantation (BMT) conditioned with total body irradiation (TBI) for acute leukemia (AL) in complete remission (CR): a study of the European group for blood and marrow transplantation

    International Nuclear Information System (INIS)

    Purpose: The advances in BMT over the past twenty years have greatly improved long term survival of patients (pts), therefore the evaluation of late complications such as cataract is of paramount importance. In order to assess the influence of several parameters on cataract formation and the risk for requiring surgery for sever opacification after BMT, we analyzed the collected data of 2149 pts from 48 EBMT centers. Patients and Methods: As of June 1996 among the 2149 questionnaires, data from 1760 pts were evaluable for survival with a median follow-up of 76 months (12-165). One thousand and ninty four pts have survived more than one year after BMT, including 5 pts who developed cataract during the first year. Thirty one pts with no ophthalmologic follow-up were excluded from the study, therefore the analyses concerned 1063 AL pts (Lymphoblastic: n = 567, 53%; Myeloblastic: n = 490, 46%; Undifferenciated: n = 6, 1%), allografted (n = 688, 65%) or autografted (n = 375, 35%) in first CR (n = 788, 74%) or in 2nd CR (n = 275, 26%). The median age was 23 years (1-57). Male to female ratio was 1.56 ((648(415))). The conditioning chemotherapy consisted of cyclophosphamide alone in 724 (68%) pts. Single dose TBI (STBI) was given a median dose of 10 Gy (6-11.82) to the mid-plane of abdomen in 495 (46%) pts, whereas fractionated regimens (FTBI; 2 to 12 fractions) were used in 568 (54%) pts, delivering a median dose of 12 Gy (8.5-12). Median dose rate (DR) was 0.06 Gy/min (0.018-0.3) in the STBI group, and 0.065 Gy/min (0.012-0.56) in the FTBI ≤ 6F group. Fifty two (5%) pts had prophylactic cranial radiotherapy delivering a median dose of 18 Gy (4-25). The administration of steroids for any reason was registered in 316 (30%) pts, and heparin as venocclusive disease (VOD) prevention in 195 (18%) pts. Results: After a median follow-up period of 76 months, (257(1063)) (24%) pts developed cataracts (unilateral in 18 and bilateral in 239 cases) with a 5 and 10-year estimated

    Full Text Available A educação de qualidade é um fator extremamente importante a ser considerado em todos os países que almejam uma sociedade mais justa e desenvolvida. No Brasil, os bens e serviços voltados à educação podem ser oferecidos tanto por entes públicos como privados. No caso dos entes públicos, a Constituição Federal de 1988 (CF/88 estabelece as responsabilidades de cada esfera de governo na prestação de serviços educacionais. Com base nesse contexto, este artigo tem como objetivo analisar o comportamento dos gastos com a função orçamentária voltada para a educação e manutenção e desenvolvimento do ensino (MDE do município de Santa Maria (RS, no período de 2007 a 2011. Para isso, utilizou-se a classificação funcional estabelecida pela Portaria nº 42/1999, do Ministério do Orçamento e Gestão, com a finalidade de acompanhar os gastos agregados em educação e o percentual das receitas aplicadas especificamente em MDE, conforme artigo 212, da CF/88 e Lei Orgânica do município. Como principais resultados, pode-se constatar o cumprimento da Lei Orgânica Municipal e do artigo 212, da CF/88, que prevê o investimento de, no mínimo 25% das receitas de impostos e transferências aplicadas na educação em MDE. No período analisado, o Índice de Desenvolvimento da Educação Básica (IDEB da 4ª e 8ª séries obteve um aumento de, aproximadamente, 17% e 13%, respectivamente, o que demonstra uma melhora na qualidade do Ensino Fundamental oferecido pela esfera municipal.The quality education is an extremely important factor to be considered in all countries who aspire to a more just and developed.

    2009-03-01

    Full Text Available An unbalanced panel data of around fifty countries between 1985 and 2003 is used to estimate the vulnerability of public social expenditures (health and education to other fiscal variables. The database allows comparisons between Latin America and the rest of developing countries. Public social expenditure is significantly lower in Latin America as share of GDP, although it has a higher share in primary expenditure. Public social expenditures in Latin America are more vulnerable to debt service, but are less sensible to changes in other types of public expenditure. As in other regions in the developing world, public social expenditure in Latin America shrinks when public debt stock increases. This effect is higher with multilateral debt obligations. In Latin America, debt defaults reduce the share of public social expenditures in total primary public expenditure.

    Los esquemas de reproducción kaleckianos se prestan para formalizar adecuadamente economías de desarrollo intermedio. sin embargo, los supuestos sobre la insensibilidad de los precios a la demanda y la inversión relacionada inversamente con el acervo de capital, no son apropiados para caracterizar este tipo de economías. El autor, prestando un nivel adecuado de realismo a su modelación, deja de lado tales supuestos al formalizar la economía por medio de 4 departamentos que incluyen uno exportador, que provee los medios de producción no elaborados internamente, y una función pública en un medio abierto. Los otros departamentos considerados proveen bienes salario y de lujo, respectivamente. Consideraciones sobre la teoría de la inversión y el trabajo productivo marxistas proveen algunas conclusiones adicionales sobre el papel que juega el Estado en las economías semi-industrializadas.

    The Kaleckian schemes of reproduction are useful to portray economies of intermediate development. But Kalecki's basic assumptions on the unsensi tiveness of prices upon demand and the inverse relationship between investment and capital stock are not appropiate to characterize this kind of economies. The author attempts to introduce an adequate level of realism into his model by leaving these assumptions aside and creating an economic model of four departments, which includes an export sector that provides inputs not internally producedo The other three departments provide wage and luxury goods. Further considerations on the Marxian theories of investment and productive labor provide additional conclusions about the role played by the state in semiindustrialized economies.

    The total nuclear reaction cross sections (σR) measurements have long been of interest since they tell us about the radii and transparency of these nuclei and give clues to understanding of their structure. For studies of unstable nuclei, in particular the physical properties of halo nuclei and the neutron skin thickness, it is valuable to know not only the root-mean-square radii (rms) but it is important to know the details of nucleusnucleus potentials. Our goal was to study total reaction cross sections (σR) by a direct measurement technique (the so-called beam attenuation or transmission method) which allows to extract model independent information. The interaction radii for 6He, 8,9Li were extracted, which are in agreement with the previous measurement at the similar energies (about a few tens of AMeV) Our results show a tendency of increasing radii as function of mass of the secondary targets.

  1. Measurement of total and partial charge changing and charge pick-up cross-sections for 300A MeV Fe26+ beam in Al with a new system of analysis

    International Nuclear Information System (INIS)

    In the present study, total and partial charge changing cross-sections of 300A MeV Fe26+ ion beam in aluminum target were measured by a new system of analysis installed with the Leica QWin Plus software. The CR39 nuclear track detectors were used to identify the incident charged particles and their fragments. The CR39 detectors just before and just after the target were calibrated and found to have the same charge response and the charge resolution, which were 0.19e and 0.20e, respectively. The response points were fitted with a polynomial of degree one and all the points are within the limits of experimental errors. The value of total charge changing cross-section was calculated to be σtot=(1663±236) mb. To determine the partial charge changing cross-sections for ΔZ=−23,−22,…,−1, number of events corresponding to each fragment were determined from multiple Gaussian fitting of diameter distributions within 95.5% confidence levels and the numbers of incident and survived beam ions were counted within 99.7% confidence levels. Charge pick-up cross-section for ΔZ=+1 was calculated and is (92±6) mb. -- Highlights: ► A good charge resolution was achieved by a new system of analysis. ► Total, partial and charge pick-up cross-sections were calculated. ► Improved threshold Z/β=4.6 was achieved. ► Beam contamination was quantified.

    Full Text Available This article aimed at both grouping municipalities in the State of São Paulo regarding profile of public expenditure per capita according to function, and describing the relationships among these groups and those obtained through the definition of the Paulista Index of Social Responsibility (IPRS. The interest in the subject stemmed from the awareness that groups of municipalities ranked by the IPRS have the same level of wealth but bear different results regarding social indices and vice-versa. The premise underlying the analyses - that the amount and quality of public expenditure would, in a way, characterize such situation - was adopted based on the characteristics of the production process of public goods. The results reached with clusters and correspondence analyses techniques showed that, to a certain degree, all municipalities presented high expenses as regards means functions; also the amount of revenue invested in social functions associated positively with the social economic indices of municipalities.O presente artigo teve como objetivo agrupar municípios paulistas quanto ao perfil dos gastos públicos per capita por função e descrever as relações entre os agrupamentos obtidos e os grupos definidos pelo Índice Paulista de Responsabilidade Social (IPRS.

    Full Text Available The purpose of this study was to compare the energy cost between genders during treadmill walking at self-selected pace; and to verify if the energy cost achieve the values recommended for weight maintenance or loss proposed by the American College of Sports Medicine (ACSM. Seventeen men and seventeen women, mean age of 23.32 ± 3.06 years, undertaken two experimental sessions: (I anthropometric measurements and a load-incremental maximum test; and, (II a 20-min walking test at self-selected pace on treadmill. Men showed a greater energy cost than women (146.18 ± 47.66 and 100.86 ± 17.04 kcal, respectively. This difference was maintained after adjust by body weight (2.2 ± 0.5 and 1.7 ± 0.2 kcal kg-1, respectively. The greater energy cost found in men can be explained by the self-selected treadmill speed that lead to a greater O2 in men. However, the exercise intensity selected by both genders did not elicit an effective energy cost that can promote weight maintenance or loss. Nonetheless, if participants performed a longer walking (> 20 minutes, they probably would achieve the energy cost recommended by the ACSM guidelines.O objetivo do presente estudo foi comparar o gasto energético entre os gêneros durante a caminhada na esteira em ritmo auto-selecionado e verificar se a intensidade que os sujeitos buscam caminhar promove um dispêndio energético dentro do recomendado para a manutenção e/ou redução do peso corporal conforme proposto pelas diretrizes do ACSM.

    Full Text Available La formación de tejido graso resulta del balance entre la ingestión y el consumo de energía, lo cual destaca la importancia del estudio de los factores que controlan el gasto energético. La hormona tiroidea es conocida desde hace tiempo como el principal regulador del metabolismo basal, a través de la estimulación del consumo de oxígeno en las células. El descubrimiento de la grasa parda y de la proteína desacoplante-1 (UCP1 demostró la importancia de este tejido para la regulación del consumo energético en mamíferos. La proteína desacoplante-2 (UCP2 se expresa en muchos tejidos y tendría una acción protectora de la función celular, al preservar el potencial de membrana afectado por el superóxido. La proteína desacoplante-3 (UCP3 estaría vinculada a la producción de calor, facilitando la combustión de ácidos grasos en la cadena respiratoria mitocondrial, pero no parece participar en el control del gasto energético. El exceso de UCP3 en ratones transgénicos disminuyó la grasa corporal y aumentó la sensibilidad a la insulina seguido de hipoglucemia, sugiriendo así un futuro, hipotético uso de esta proteína en la diabetes 2 y en la obesidad. Los estudios que se realizan sobre estas proteínas y sobre hormonas del tejido adiposo blanco como la leptina, adiponectina, resistina, de péptidos hipotalámicos como neuropéptido Y, CRF, hormona alfa-melanocítica y péptidos regulados por cocaína y anfetamina (CART, muestran resultados promisorios para una futura aplicación en el control del gasto energético en humanos y con ello en la prevención o el tratamiento de la obesidad y la diabetes tipo 2.Accumulation of fat in the tissues results from the balance between energy intake and expenditure.

    Full Text Available OBJECTIVE: Compare patterns of catastrophic health expenditures in 12 countries in Latin America and the Caribbean. MATERIAL AND METHODS: Prevalence of catastrophic expenses was estimated uniformly at the household level using household surveys. Two types of prevalence indicators were used based on out-of-pocket health expense: a relative to an international poverty line, and b relative to the household's ability to pay net of their food basket. Ratios of catastrophic expenditures were estimated across subgroups defined by economic and social variables. RESULTS: The percent of households with catastrophic health expenditures ranged from 1 to 25% in the twelve countries. In general, rural residence, lowest quintile of income, presence of older adults, and lack of health insurance in the household are associated with higher propensity of catastrophic health expenditures. However, there is vast heterogeneity by country. CONCLUSIONS: Cross national studies may serve to examine how health systems contribute to the social protection of Latin American households.OBJETIVO: Comparar los patrones de gastos catastróficos en salud en 12 países de América Latina y el Caribe.

    The first total synthesis of dilignan Boehmenan has been achieved. A biomimetic oxidative coupling of the ferulic acid methyl ester in the presence of silver oxide is the crucial step in the synthesis sequence, generating the dihydrobenzofuran skeleton. Hydroxyl group was protected with DHP and reducted with LiAlH4 to afford the intermediate diol. The diol was condensated with the derivative of ferulic acid, then removed the protecting groups, to get Boehmenan. Meanwhile, a study on the ring-opening reaction of the intermediate dihydrobenzofuran neolignan under base conditions was described.

    Full Text Available La fístula enterocutánea es la forma más común de las fístulas intestinales. Es una patología que obliga la estancia hospitalaria prolongada debido a complicaciones como desequilibrio hidroelectrolítico, desnutrición, desajustes metabólicos y sepsis. El apoyo nutricio es parte esencial en el manejo, ya que favorece la función intestinal, inmune, promueve la cicatrización y disminuye el catabolismo. Aunque se ha reconocido la importancia del apoyo nutricio no existen ensayos clínicos sobre su manejo integral, lo cual puede resultar limitante al establecer estrategias específicas. Se desconoce el desajuste metabólico que ocasiona una fístula. Para fístulas de bajo gasto, se recomienda cubrir el gasto energético en reposo, con un aporte de 1,0 a 1,5 g/kg/d de proteína; mientras que en fístulas de alto gasto puede aumentar hasta 1,5 veces su requerimiento, con un aporte de proteína de 1,5 y hasta 2,5 g/kg. Se recomienda el aporte del doble del requerimiento de vitaminas y elementos traza y entre 5 y 10 veces el de Vitamina C y Zinc, especialmente para fístulas de alto gasto. La decisión de elegir entre la vía enteral o parenteral dependerá de la evaluación de cada paciente, del tipo y localización de la fístula, estado nutricio previo, entre otros. Siempre que sea posible debe preferirse la vía enteral; y cuando no se pueda cubrir el requerimiento por esta vía, combinar con nutrición parenteral. Otras estrategias de tratamiento nutricio en fístulas podrían incluir el uso de inmunomoduladores e incluso el manejo de estrés.

    Full Text Available Abstract Definition of the disease AL amyloidosis results from extra-cellular deposition of fibril-forming monoclonal immunoglobulin (Ig light chains (LC (most commonly of lambda isotype usually secreted by a small plasma cell clone. Most patients have evidence of isolated monoclonal gammopathy or smoldering myeloma, and the occurrence of AL amyloidosis in patients with symptomatic multiple myeloma or other B-cell lymphoproliferative disorders is unusual. The key event in the development of AL amyloidosis is the change in the secondary or tertiary structure of an abnormal monoclonal LC, which results in instable conformation. This conformational change is responsible for abnormal folding of the LC, rich in β leaves, which assemble into monomers that stack together to form amyloid fibrils. Epidemiology AL amyloidosis is the most common type of systemic amyloidois in developed countries with an estimated incidence of 9 cases/million inhabitant/year. The average age of diagnosed patients is 65 years and less than 10% of patients are under 50. Clinical description The clinical presentation is protean, because of the wide number of tissues or organs that may be affected. The most common presenting symptoms are asthenia and dyspnoea, which are poorly specific and may account for delayed diagnosis. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. They are characterized by heavy proteinuria, with nephrotic syndrome and impaired renal function in half of the patients. Heart involvement, which is present at diagnosis in more than 50% of patients, leading to restrictive cardiopathy, is the most serious complication and engages prognosis. Diagnostic methods The diagnosis relies on pathological examination of an involved site showing Congo red-positive amyloid deposits, with typical apple-green birefringence under polarized light, that stain positive with an anti-LC antibody by immunohistochemistry and

    Full Text Available O objetivo deste estudo consistiu em analisar os impactos gerados pela Lei de Responsabilidade Fiscal, no que tange ao comprometimento da receita corrente com as despesas com pessoal, em três anos de sua vigência, ou seja, comparando-se os gastos dos exercícios de 1999 com 2001 e 1999 com 2002. Utilizou-se uma amostra de 86 municípios do Estado da Paraíba, buscando verificar a existência de diferenças significativas entre os níveis de comprometimento das Receitas Correntes Líquidas com gastos de pessoal a partir do teste não-paramétrico de Mann-Whitney. Concluiu-se que quando se analisa 1999 com relação a 2001 percebe-se que o esforço para redução de despesa com pessoal ainda não é estatisticamente perceptível. No entanto, quando se analisa 1999 com relação a 2002, infere-se que houve diminuição significativa, do ponto de vista da estatística da participação das despesas com pessoal na receita corrente de 2002 em relação a 1999. Palavras Chaves: Lei de Responsabilidade Fiscal, despesas com pessoal e receita corrente líquida. Abstract The aim of this study is to analyse the impacts generated by the Fiscal Responsibility Law, with reference to the commitment of the current revenue with expenditures with staff, in three years, comparing the expenses of the exercises of 1999 with those of 2001 and the ones of 1999 with those of 2002. A sample of 86 cities of the State of Paraíba was used with an attempt to verify the existence of significant differences between the levels of commitment of the Liquid Current Revenues with expenses with staff from the Mann-Whitney’s nonparametric tests. It was concluded that when 1999 is compared to 2001, one can notice that the effort for the reduction of expenditure with staff is still not statistically perceivable. However, when 1999 is observed in comparison to 2002, it is visible that there was a significant reduction in the participation of expenditures with staff in the current

A amostra investigada foi constituída por 14 municípios do Estado do Rio Grande do Norte. A pesquisa envolveu coleta de dados referente às transferências, recursos próprios municipais e gastos com atenção básica. Na análise da gestão foi realizado um levantamento junto aos dirigentes locais e conselheiros. Observa-se que o financiamento do Sistema Único de Saúde se faz às expensas das transferências federais e receitas municipais, com pequena participação dos recursos estaduais. A direção dos gastos tem privilegiado a atenção básica. No processo de gestão, verifica-se centralização das ações nas prefeituras. As secretarias municipais e os conselhos cumprem em parte a legislação e apresentam dificuldades na autonomia e o controle social.

MATERIAL Y MÉTODOS: Los costos de la atención médica se estimaron desde la perspectiva del proveedor y se empleó la metodología del costeo de enfermedad. A partir de una muestra de pacientes (n= 1 596 atendidos en las unidades médicas se estableció la frecuencia de utilización de servicios en los tres niveles de atención. Para cada enfermedad se consideraron costos promedio por paciente y costos totales de enfermedad, los cuales se mensuraron en pesos mexicanos de 2004. Se calculó la fracción atribuible al consumo de tabaco para cada enfermedad, misma que se usó para atribuir los costos al tabaco. RESULTADOS: Los costos totales anuales de atención médica nacional corresponden a 7 114 millones para el infarto agudo del miocardio, 3 424 millones para la enfermedad vascular cerebral, 1 469 millones para la enfermedad pulmonar obstructiva crónica y 102 millones para el cáncer pulmonar. El costo total anual para el IMSS por estas cuatro enfermedades asciende a 12 100 millones de pesos. Los costos atribuibles al consumo de tabaco corresponden a 7 100 millones de pesos, lo cual equivale a 4.3% del gasto de operación de la institución en el año 2004. CONCLUSIONES: Estos resultados confirman el elevado costo de la atención médica de las enfermedades atribuibles al consumo de tabaco en el IMSS y generan información de primera mano necesaria para impulsar las medidas de prevención en esa institución y reforzar las políticas de control del tabaquismo ya aplicadas en México.OBJECTIVE: To estimate the cost of medical care for the major diseases attributable to tobacco consumption at the IMSS.

    Full Text Available Physiological workload is used to estimate the physical demand of tasks in the workforce, but limited information is available for the various work activities in developing countries. Eighty-three randomly selected male workers participated in the present study, aimed at assessing the physiological workload of garbage collection (GC in Rio de Janeiro, Brazil. Heart rate (HR was obtained on four consecutive workdays. Energy expenditure (EE was extrapolated from heart rate data based on individual laboratory-established heart rate/oxygen consumption curve in 70 workers. Mean HR during GC was 104.0 ± 11.7bpm (± SD, representing 56.9 ± 7.5% of maximum heart rate. EE was 1608.3 ± 738.5kcal for an average of 293.1 ± 103.9 minutes of work per day. Based on all measurements, work in garbage collection in Rio de Janeiro can be considered excessively heavy. These data emphasize the need to develop appropriate classification of workload to be used in health-related research and in the development of maximum acceptable work time in association with the physiological workload, particularly in developing countries.A carga de trabalho fisiológica é utilizada para estimar a demanda física de uma tarefa na população de trabalhadores adultos; no entanto, nos países em desenvolvimento há poucos dados disponíveis sobre as diversas atividades ocupacionais.

A freqüência cardíaca foi medida em quatro dias de trabalho consecutivos. O gasto energético foi extrapolado a partir da freqüência cardíaca, com base em dados individuais obtidos em laboratório para a curva de freqüência cardíaca/consumo de oxigênio em 70 trabalhadores. A freqüência cardíaca média durante a coleta de lixo era 104,0 ± 11,7bpm, o que representa 56,9 ± 7,5% da freq

  19. Total Energy Monitor

    Energy Technology Data Exchange (ETDEWEB)

    Friedrich, S

    2008-08-11

    The total energy monitor (TE) is a thermal sensor that determines the total energy of each FEL pulse based on the temperature rise induced in a silicon wafer upon absorption of the FEL. The TE provides a destructive measurement of the FEL pulse energy in real-time on a pulse-by-pulse basis. As a thermal detector, the TE is expected to suffer least from ultra-fast non-linear effects and to be easy to calibrate. It will therefore primarily be used to cross-calibrate other detectors such as the Gas Detector or the Direct Imager during LCLS commissioning. This document describes the design of the TE and summarizes the considerations and calculations that have led to it. This document summarizes the physics behind the operation of the Total Energy Monitor at LCLS and derives associated engineering specifications.

Materiales y métodos: Estudio de casos y de controles con una muestra de gestantes que asistieron al CP en 7 instituciones. Se aplicó un cuestionario para la recolección de información a 823 gestantes. Otro cuestionario fue aplicado a 4 enfermeras encargadas de manejar los programas de CP. La variable dependiente fue el acceso al CP y las independientes: la presencia de barreras administrativas, económicas, geográficas y percepción del trato, orientación brindada y aspecto físico de los servicios de salud. Las variables que indagaron por las estrategias de búsqueda activa fueron: proporción de gestantes inscritas en el primer trimestre, utilización de folletos y carteles informativos para generar conciencia sobre la importancia del acceso oportuno al CP. Resultados: Factores como la etnia (P = 0, 01, el tipo de afiliación al régimen de salud (P = 0,001, actividad de la madre en el último mes (P = 0,04, baja capacidad económica (P = 0,038, no estar afiliada al Sistema General de Seguridad Social en Salud (SGSSS (P < 0,001 y la tramitología (P = 0,003 presentaron diferencias significativas entre los grupos.

    INTRODUCTION Atmospheric total OH reactivity (Rtotal) can be measured (Kovacs and Brune, 2001; Sinha et al., 2008) or it can be calculated according to Rtotal = ∑i kOH+X_i [Xi] where kOH+X_i corresponds to the reaction rate coefficient for the reaction of OH with a given compound Xi and [Xi] its concentration. Studies suggest that in some environments a large fraction of missing reactivity, comparing calculated Rtotal with ambient total OH reactivity measurements (Di Carlo et al., 2004; Hofzumahaus et al., 2009). In this study Rtotal has been measured using the Comparative Reactivity Method (Sinha et al., 2008). Levels of the reference compound (pyrrole, C4H5N) are monitored by gas chromatography every 2 minutes and Rtotal is derived from the difference of reactivity between zero and ambient air. RESULTS Around 36 hours of preliminary total OH reactivity data (30 May until 2 June 2015) are presented in Fig. 1. Its range matches previous studies for this site (Nölscher et al., 2012; Sinha et al., 2010) and is similar to values in another pine forest (Nakashima et al., 2014). The setup used during the period presented here has been updated and more recent data will be presented, as well as a comparison with calculated OH reactivity from measured individual species.

    The first total synthesis of the cyclic depsipeptide natural product teixobactin is described. Synthesis was achieved by solid-phase peptide synthesis, incorporating the unusual l-allo-enduracididine as a suitably protected synthetic cassette and employing a key on-resin esterification and solution-phase macrolactamization. The synthetic natural product was shown to possess potent antibacterial activity against a range of Gram-positive pathogenic bacteria, including a virulent strain of Mycobacterium tuberculosis and methicillin-resistant Staphylococcus aureus (MRSA).

    Full Text Available The focus of competitive "battle" shifted from the price towards non-price instruments, above all, towards quality that became the key variable for profitability increase and achievement of better comparative position of a company. Under such conditions, management of a company, which, according to the established and certified system of total quality, strives towards achieving of a better market position, faces the problem of quality cost measurement and determination. Management, above all, cost accounting can help in solving of this problem, but the question is how much of its potential is being used for that purpose.

    Confronted by changing market conditions and increased global competition, in 1983 the Commercial Nuclear Fuel Division (CNFD) of Westinghouse Electric embarked on an ambitious plan to make total quality the centerpiece of its long-term business strategy. Five years later, the division's efforts in making continuous quality improvement a way of life among its more than 2,000 employees gained national recognition when it was named a charter recipient of the Malcolm Baldridge National Quality Award. What CNFD achieved during the 1980s was a cultural transformation, characterized by an empowered work force committed to a common vision.

    Successful implant placement at the time of extraction has been documented. Implant placement at the time of extraction was initially performed as a two-stage procedure often with barrier membranes and sophisticated second-stage surgical uncoverings. The authors describe the next generation of this technique, including atraumatic tooth removal with simultaneous root form, implant placement, and temporization at one appointment. This technique of "Immediate Total Tooth Replacement" allows for the maintenance of the bony housing and soft-tissue form that existed before extraction, while at the same time establishing a root form anchor in the bone for an esthetic restoration.

    Total synthesis of (-)-daphenylline, a hexacyclic Daphniphyllum alkaloid, was achieved. Construction of the tricyclic DEF ring system was initiated by asymmetric Negishi coupling followed by an intramolecular Friedel-Crafts reaction. Installation of a side chain onto the tricyclic core was carried out through Sonogashira coupling, stereocontrolled Claisen rearrangement by taking advantage of the characteristic conformation of the tricyclic DEF core, and the stereoselective alkylation of a lactone. After the introduction of a glycine unit, the ABC ring system was stereoselectively constructed through intramolecular cycloaddition of the cyclic azomethine ylide. PMID:27062676

    Full Text Available The neutron time of flight facility nELBE, produces fast neutrons in the energy range from 0.1 MeV to 10 MeV by impinging a pulsed relativistic electron beam on a liquid lead circuit [1]. The short beam pulses (∼10 ps and a small radiator volume give an energy resolution better than 1% at 1 MeV using a short flight path of about 6 m, for neutron TOF measurements. The present neutron source provides 2 ⋅ 104  n/cm2s at the target position using an electron charge of 77 pC and 100 kHz pulse repetition rate. This neutron intensity enables to measure neutron total cross section with a 2%–5% statistical uncertainty within a few days. In February 2008, neutron radiator, plastic detector [2] and data acquisition system were tested by measurements of the neutron total cross section for 181Ta and 27Al. Measurement of 181Ta was chosen because lack of high quality data in an anergy region below 700 keV. The total neutron cross – section for 27Al was measured as a control target, since there exists data for 27Al with high resolution and low statistical error [3].

A partir de tal premisa, el Tribunal de Justicia de la Unión Europea ha debido intervenir para solucionar diversos litigios derivados de la prestación de servicios sanitarios o del denominado “turismo sanitario a la carta”. En concreto, a propósito de los gastos de atención médica en otros Estados miembros de la Unión Europea y su posterior reintegro en el Estado de origen del asegurado en función de las normas de Seguridad Social de éste último país.

Sob a ótica dos especialistas em orçamento, a questão está em escolher a melhor maneira de usar as informações geradas pela contabilidade de competência para aumentar a eficiência e melhorar a qualidade do gasto. Uns defendem que tais informações devem ser vistas como mais uma ferramenta importante para a melhoria das decisões sobre o uso dos recursos públicos. Outros, que elas poderiam revolucionar o processo orçamentário levando à posterior adoção do orçamento de competência. Este artigo explora essa questão, com base na análise de experiências internacionais, apontando para aspectos relevantes que devem ser observados na sequência dos debates sobre esse tema no BrasilAllocation and management of public funds can be significantly improved when good information on costs of producing and delivering public goods and services is regularly available, so that tax payers' money can bring better social benefits. Pundits diverge on which is the best way to use the information on government costs extracted from the adoption of accrual accounting in the public sector. Some argue in favor of using such information as an important tool for improving decision making during the regular budgetary process. Others support the idea of revolutionizing the whole budget by adopting the so-called accrual budgeting. This article explores this question on the basis of evidences provided by international experiences and points to important elements that should be taken into account in the ongoing debate in Brazil

    Due to their architectural intricacy and biological significance, the synthesis of polycyclic diterpenes and their biogenetically related alkaloids have been the subject of considerable interest over the last few decades, with progress including the impressive synthesis of several elusive targets. Despite tremendous efforts, conquering the unique structural types of this large natural product family remains a long-term challenge. The arcutane diterpenes and related alkaloids, bearing a congested tetracyclo[5.3.3.0(4,9).0(4,12)]tridecane unit, are included in these unsolved enigmas. Here we report a concise approach to the construction of the core structure of these molecules and the first total synthesis of (±)-atropurpuran. Pivotal features of the synthesis include an oxidative dearomatization/intramolecular Diels-Alder cycloaddition cascade, sequential aldol and ketyl-olefin cyclizations to assemble the highly caged framework, and a chemoselective and stereoselective reduction to install the requisite allylic hydroxyl group in the target molecule.

    The development and testing of a breadboard version of a highly sensitive total-organic-carbon (TOC) analyzer are reported. Attention is given to the system components including the CO2 sensor, oxidation reactor, acidification module, and the sample-inlet system. Research is reported for an experimental reagentless oxidation reactor, and good results are reported for linearity, sensitivity, and selectivity in the CO2 sensor. The TOC analyzer is developed with gravity-independent components and is designed for minimal additions of chemical reagents. The reagentless oxidation reactor is based on electrolysis and UV photolysis and is shown to be potentially useful. The stability of the breadboard instrument is shown to be good on a day-to-day basis, and the analyzer is capable of 5 sample analyses per day for a period of about 80 days. The instrument can provide accurate TOC and TIC measurements over a concentration range of 20 ppb to 50 ppm C.

    2016-02-01

    Ankle arthritis results in a stiff and painful ankle and can be a major cause of disability. For people with end-stage ankle arthritis, arthrodesis (ankle fusion) is effective at reducing pain in the shorter term, but results in a fixed joint, and over time the loss of mobility places stress on other joints in the foot that may lead to arthritis, pain and dysfunction. Another option is to perform a total ankle joint replacement, with the aim of giving the patient a mobile and pain-free ankle. In this article we review the efficacy of this procedure, including how it compares to ankle arthrodesis, and consider the indications and complications. PMID:26868932

    The Total Quality at Source philosophy is based on optimizing the effectiveness of people in achieving ZERO-DEFECT results. In this paper a philosophy of what, I have come to perceive, it takes to get people to perform to the very best of their abilities and thereby achieve the best results they can, is presented. In the examples I shall describe I have played an instrumental role since it has become my belief that any job can always be done better provided that the people doing it can themselves become convinced that they can do better. Clearly there are many ideas on how to do this. The philosophy that I am presenting in this paper is based on my own experience, where I have both participated and observed it being applied; its effectiveness may be judged by the results.

    2014-02-01

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine. PMID:24412045

  13. Total process surveillance (TOPS)

    International Nuclear Information System (INIS)

    Understanding the current operating behaviour of a process or power plant is the key to maximizing the efficiency and safety of operation and the quality of the product. Early detection of plant component or sensor degradation and failure improves operating safety, product quality and plant availability. This paper describes the design and development of a Total Process Surveillance system which assimilates all the sensor information available on a plant to provide the operators with a succinct report on the status of the plant behaviour. The heart of the system is a robust model-based observer which can estimate internal plant states, and provides a residual signal with powerful fault detection and isolation features. Several results are presented which illustrate the performance of the system in detecting and isolating multiple fault scenarios in a fast reactor plant. A structure for the practical implementation of the system is described, and comments are given on its contribution to the final experimental work planned for AEA Technology's Prototype Fast Reactor (PFR).

  17. Total Process Surveillance (TOPS)

    International Nuclear Information System (INIS)

    analytical redundancy is of significant importance in order to obtain the maximum amount of information as to the state of the plant. A further logical step in this theory is the accommodation of failed or damaged transducers by deriving their measurement information from the available remaining transducers. A system capable of providing a clear and improved picture of the plant's behaviour under a range of normal and off-normal operating conditions would thus be of significant economical and safety benefit. In summary: A Total Process Surveillance system is under development which can provide, in real-time, additional process information from a limited number of raw measurement signals. This is achieved by using a robust model based observer to generate estimates of the process' internal states. The observer utilises the analytical redundancy among a diverse range of transducers and can thus accommodate off-normal conditions which lead to transducer loss or damage. The modular hierarchical structure of the system enables the maximum amount of information to be assimilated from the available instrument signals no matter how diverse. This structure also constitutes a data reduction path thus reducing operator cognitive overload from a large number of varying, and possibly contradictory, raw plant signals. The TOPS system provides a structured and complete means for plant data management under both normal and off-normal operating conditions and thus will significantly assist the operator during severe accident management

    Surface phonon polariton (SPP) characteristics of In(0.04)Al(0.06)Ga(0.90)N/AlN/Al(2)O(3) heterostructure are investigated by means of p-polarized infrared (IR) attenuated total reflection spectroscopy. Two absorption dips corresponding to In(0.04)Al(0.06)Ga(0.90)N SPP modes are observed. In addition, two prominent dips and one relatively weak and broad dip corresponding to the Al(2)O(3) SPP mode, In(0.04)Al(0.06)Ga(0.90)N/Al(2)O(3) interface mode, and Al(2)O(3) bulk polariton mode, respectively, are clearly seen. No surface mode feature originating from the AlN layer is observed because it is too thin. Overall, the observations are in good agreement with the theoretical predictions. PMID:20588890

    Investigation of commercially produced hydrolysis salts of aluminum by solid-state (27)Al NMR spectroscopy and size-exclusion chromatography (SEC) reveals well-defined and distinct Al environments that can be related to physicochemical properties. (27)Al MAS and MQ-MAS NMR spectroscopic data show that the local structure of the solids is dominated by moieties that closely resemble the Al30 polyoxocation (Al30O8(OH)56(H2O)26(18+)), accounting for 72-85% of the total Al. These Al30-like clusters elute as several size fractions by SEC. Comparison of the SEC and NMR results indicates that the Al30-like clusters includes intact isolated clusters, moieties of larger polymers or aggregates, and possibly fragments resembling δ-Al13 Keggin clusters. The coagulation efficacy of the solids appears to correlate best with the abundance of intact Al30-like clusters and of smaller species available to promote condensation reactions. PMID:27232539

    [AlO4Al12(OH)24(H2O)12]7+(Al13) formation in electrolysis process is studied. The results detected by 27Al NMR spectroscopy show that high content of Al13 polymer is formed in the partially hydrolyzed aluminum solution prepared by controlled electrolysis process. In the produced electrolyte of total Al concentration (Al) 2.0 mol* L-1 with a basicity (B = OH/Al molar ratios) of 2.0, the content of Al13 polymer is over 60% of total Al. Dynamic light scattering shows that the size distribution of the final electrolyte solutions ( = 2.0 mol*L-1) is trimodal with B = 2.0 and bimodal with B = 2.5. The aggregates of Al13 complexes increase the particle size of partially hydrolyzed aluminum solution.

El desarrollo mantuvo su vigencia entre 1945 y 1975, cuando al advenimiento del neoliberalismo fue paulatinamente retirado de la agenda de las preocupaciones nacionales e internacionales. Al iniciarse el siglo xxi, el fracaso del mercado autorregulado trajo de nueva cuenta al debate los problemas del desarrollo, lo que obliga a revisarlo críticamente, tanto como al concepto mismo para mostrar su carácter colonial, si se quiere construir caminos ajenos al neoliberal y superar los problemas que han hecho de Latinoamérica una de las regiones más desiguales del mundo.

    Let G=(V,E) be a simple graph. For any real valued function f:V→R, the weight of f is f(V)=∑f(v) over all vertices v∈V. A signed total dominating function is a function f:V→{-1,1} such that f(N(v))≥1 for every vertex v∈V. The signed total domination number of a graph G equals the minimum weight of a signed total dominating function on G. In this paper, some properties of the signed total domination number of a graph G are discussed.

    The objective of this study was to characterize the diagnostic timelines and their predictors in people with amyotrophic lateral sclerosis (ALS). Patients were identified through ALS billing codes. Time from presenting symptom to first doctor visit, first doctor visit to suspected ALS diagnosis, suspected to confirmed ALS diagnosis, and presenting symptom to confirmed ALS diagnosis (total diagnostic time) were collected. Regression models were used to analyze the predictors of diagnostic delay. Three hundred and four ALS patients were included in the analysis. Median total diagnostic time was 11.5 months. Diagnostic timelines were longer in patients with age > 60 years (p < 0.001), sporadic ALS (p = 0.043), and limb onset (p = 0.010). The presence of fasciculations, slurred speech, and lower extremity weakness when symptoms were first noted were independent predictors of shorter time to ALS diagnosis (p = 0.04, p = 0.02, and p = 0.04, respectively). About half of the patients (52%) received an alternative diagnosis and each patient saw an average of three different physicians before ALS diagnosis was confirmed. In conclusion, diagnostic timelines in ALS are long, and patients see many physicians and receive multiple alternative diagnoses before the diagnosis of ALS is confirmed. Older age, sporadic disease, and limb onset can delay ALS diagnosis. PMID:24981792

  18. Study of the total reaction cross section via QMD

    International Nuclear Information System (INIS)

    This paper presents a new empirical formula to calculate the average nucleon-nucleon (N-N) collision number for the total reaction cross sections (σR). Based on the initial average N-N collision number calculated by quantum molecular dynamics (QMD), quantum correction and Coulomb correction are taken into account within it. The average N-N collision number is calculated by this empirical formula. The total reaction cross sections are obtained within the framework of the Glauber theory. σR of 23Al+12C, 24Al+12C, 25Al+12C, 26Al+12C and 27Al+12C are calculated in the range of low energy. We also calculate the σR of 27Al+12C with different incident energies. The calculated σR are compared with the experimental data and the results of Glauber theory including the σR of both spherical nuclear and deformed nuclear. It is seen that the calculated σR are larger than σR of spherical nuclear and smaller than σR of deformed nuclear, whereas the results agree well with the experimental data in low-energy range.

    Two trimetallic ZnCuAl and MnCuAl hydrotalcites have been successfully synthesized by a co-precipitation method. The manganese based material was identified as a new hydrotalcite phase. Both lamellar precursors were calcined at 450 and 600 deg. C and the resulting catalysts were tested on reaction of total oxidation of toluene. The solids were characterized by X-ray diffraction, thermal analysis, atomic absorption spectroscopy, Fourier transformed infrared spectroscopy, N{sub 2} adsorption and H{sub 2} temperature-programmed reduction. It was found that ZnCuAl materials are composed of copper and zinc oxides supported on alumina; while MnCuAl ones comprise basically spinel phases, which were not completely identified. The catalytic behavior of the calcined samples showed that Mn hydrotalcite calcined at 450 deg. C exhibited the best catalytic performance that corresponds to 100% toluene conversion into CO{sub 2} at about 300 deg. C.

    2014-05-01

    ALS is likely to be a disorder of multifactorial origin. Among all the factors that may increase the risk of ALS, environmental ones are being studied for many years, but in the recent years, several advances have pointed to a new interest in their potential involvement in the disease process, especially for the cyanotoxin BMAA. Food containing BMAA has been found on Guam, a well-known focus of ALS/parkinsonism/dementia and high levels of BMAA have been identified into the brain of these patients. The BMAA cyanotoxin is potentially ubiquitous and have also been found into the food of patients who died from ALS both in Europe and USA. BMAA can be wrongly integrated into the protein structure during mRNA traduction, competing with serine. This may induce abnormal protein folding and a subsequent cell death. Heavy metals, such as lead or mercury may be directly toxic for neuronal cells. Several works have suggested an increased risk of ALS in individuals chronically exposed to these metals. Exposure to pesticides has been suggested to be linked to an increased risk of developing ALS. The mechanism of their toxicity is likely to be mediated by paraoxonases. These proteins are in charge of detoxifying the organism from toxins, and particularly organophosphates. To date, there are insufficient scientific data to suggest that exposure to electromagnetic fields may increase the risk of having ALS. We are particularly missing longitudinal cohorts to demonstrate that risk. PMID:24703731

    Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life. FIABA promotes the concept of sustainable mobility for all, supported by the European Commission’s White Paper.

We conclude that due to the small charm quark mass, which amplifies the effect of the other parameters in the calculation, the uncertainty on the total charm cross section is difficult to quantify.

  7. Total body water and total body potassium in anorexia nervosa

    International Nuclear Information System (INIS)

    In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation

    Full Text Available Introduction: Routine hemithyroidectomy during total laryngectomy in the setting of advanced stage of laryngeal carcinoma without clear thyroid involvement remains a controversial issue. This study was conducted to assess the rate of thyroid gland involvement in the patients without obvious clinical involvement who were candidates for total laryngectomy. Materials and Methods: In this cross-sectional study, between 1994 and 2007, 186 patients who underwent total laryngectomy with ipsilateral hemithyroidectomy at Imam Khomeini hospital of Ahwaz Jondishapour university, were investigated for thyroid gland involvement. Results: Of 186 patients, 169 cases were men and 17 were women, with mean age of 63 years. Microscopic tissue study revealed tumor invasion to thyroid gland in 7 patients, all of them had clinically advanced disease. Among these patients, 5 cases had transglottic cancer and 2 cases had subglottic cancer. Moreover, 4 patients had thyroid cartilage invasion and in one patient pyriform sinus was involved. Conclusion: There may be no need for thyroidectomy in all total laryngectomy cases. We recommend hemithyroidectomy with isthmectomy during total laryngectomy only in cases with subglottic tumor extension, thyroid cartilage invasion, and pyriform sinus involvement.

    The most frequently used methods to reduce fusion and total reaction excitation functions were investigated in a very recent paper Canto et al. (Phys Rev C 92:014626, 2015). These methods are widely used to eliminate the influence of masses and charges in comparisons of cross sections for weakly bound and tightly bound systems. This study reached two main conclusions. The first is that the fusion function method is the most successful procedure to reduce fusion cross sections. Applying this method to theoretical cross sections of single channel calculations, one obtains a system independent curve (the fusion function), that can be used as a benchmark to fusion data. The second conclusion was that none of the reduction methods available in the literature is able to provide a universal curve for total reaction cross sections. The reduced single channel cross sections keep a strong dependence of the atomic and mass numbers of the collision partners, except for systems in the same mass range. In the present work we pursue this problem further, applying the reduction methods to systems within a limited mass range. We show that, under these circumstances, the reduction of reaction data may be very useful.

    Full Text Available Total thyroidectomy can be performed with low rate of injuries of the recurrent laryngeal nerves and parathyroid glands, with appropriate techniques. The paper describes the technique of total thyroidectomy using capsular dissection and the indications of this operation. There are some steps which should be respected: good exposure of the thyroid gland, careful dissection of the superior pole using the avascular plane between superior pole and cricothyroid muscle, medial retraction of the gland, ligating the tertiary (third order branches of the inferior thyroid artery, near the surface of thyroid parenchyma. Using this type of dissection, the recurrent laryngeal nerves are protected, as well as the blood supply of the parathyroid glands. Conclusions: Total thyroidectomy using capsular dissection is the procedure of choice for multinodular goiter, because avoid the completion thyroidectomy for recurrence or occult thyroid cancer.

    We derive the spontaneous anisotropy of the resistivity of the ferromagnetic compound PrAl2 from magnetoresistance measurements on a single crystal of PrAl2. We ascribe this spontaneous anisotropy of the resistivity to scattering of the conduction electrons by the thermal quadrupole disorder and we account for our experimental results by using the theoretical model previously developed by us. We find that quadrupole scattering gives a very important contribution to the total magnetic disorder (spin and quadrupole) resistivity but that only a small part of this quadrupole contribution is anisotropic.

    The application of compound parts of Al-[AlBO]w/Al not only reduces the cost of the parts but also improves its properties. However, there is a large thermal residual stress between Al and [AlBO]w/Al, and it is harmful for practical application. From the theoretical analyses and experimental results, it was found that by the compressive pre-plastic deformation perpendicular to the interface between Al and [AlBO]w/Al, the interlayer residual stress of compound parts can be reduced, while the mechanical properties of compound parts can be improved.

Neste artigo, buscou-se apreender a evolução do financiamento e do gasto com saúde nos municípios paulistas com população superior a 500.000 habitantes, excluído o município da capital, entre 2000 e 2006, estabelecendo um paralelo com a oferta de serviços ao longo deste período, utilizando-se para tanto os dados da Fundação Seade, do Siops e do Datasus. Conclui-se que há um gasto crescente com saúde superior ao crescimento da receita e da despesa global. Considerando os baixos valores de cobertura do PSF e o crescimento experimentado pela produção de procedimentos de média e alta complexidades, os recursos parecem direcionados para reprodução do modelo médico-assistencial tradicional. A heterogeneidade dos indicadores apresentados pelos diversos municípios apontam para a necessidade de estudos de casos, tanto simples quanto múltiplos, com vistas à identificação dos determinantes dessas diferenças.Challenges to implantation of SUS doutrinary and operative principles in great urban centers, have stimulated the developing of strategies focused on cities over 100.000 inhabitants and had raised researches on this setting.

    Background: A cluster of genes are involved in the pathogenesis and adhesion of Candida albicans to mucosa and epithelial cells in the vagina, the important of which is agglutinin-like sequence (ALS) genes. As well as vaginitis is a significant health problem among women, the antifungal resistance of Candida species is continually increasing. This cross-sectional study investigates the expression of ALS1 and ALS3 genes and biofilm formation in C. albicans isolate isolated from vaginitis. Materials and Methods: Fifty-three recognized isolates of C. albicans were collected from women with recurrent vulvovaginal candidiasis in Iran, cultured on sabouraud dextrose agar, and then examined for gene expression. Total messenger RNA (mRNA) extracted from C. albicans isolates and complementary DNA synthesized using reverse transcriptase enzyme. Reverse transcription-polymerase chain reaction (RT-PCR) using specific primer was used to evaluate the expression of ALS1 and ALS3 through housekeeping (ACT1) genes. 3-(4,5-dimethyl-2-thiazyl)-2,5-diphenyl-2H-tetrazolium bromide assay was performed to assess adherence capacity and biofilm formation in the isolated. Results: Forty isolates (75.8%) expressed ALS1 and 41 isolates (77.7%) expressed ALS3 gene. Moreover, 39 isolates (74%) were positive for both ALS1 and ALS3 mRNA by the RT-PCR. Adherence capability in isolates with ALS1 or ALS3 genes expression was greater than the control group (with any gene expression), besides, it was significantly for the most in the isolates that expressed both ALS1 and ALS3 genes simultaneously. Conclusion: The results attained indicated that there is an association between the expression of ALS1 and ALS3 genes and fluconazole resistance in C. albicans. A considerable percent of the isolates expressing the ALS1 and ALS3 genes may have contributed to their adherence to vagina and biofilm formation. PMID:27376044

    Diffusion couples of aluminum and copper were fabricated by explosive welding process. The interface evolution caused by annealing at different temperatures and time durations was investigated by means of optical microscopy, scanning electron microscopy equipped with energy dispersive spectroscopy, and x-ray diffraction. Annealing in the temperature range of 573 K to 773 K (300 °C to 500 °C) up to 408 hours showed that four types of intermetallic layers have been formed at the interface, namely Al2Cu, AlCu, Al3Cu4, and Al4Cu9. Moreover, it was observed that iron trace in aluminum caused the formation of Fe-bearing intermetallics in Al, which is near the interface of the Al-Cu intermetallic layers. Finally, the activation energies for the growth of Al2Cu, AlCu + Al3Cu4, Al4Cu9, and the total intermetallic layer were calculated to be about 83.3, 112.8, 121.6, and 109.4 kJ/mol, respectively. Considering common welding methods (i.e., explosive welding, cold rolling, and friction welding), although there is a great difference in welding mechanism, it is found that the total activation energy is approximately the same.

    We introduce the concept of an edge-colouring total k-labelling. This is a labelling of the vertices and the edges of a graph G with labels 1, 2, ..., k such that the weights of the edges define a proper edge colouring of G. Here the weight of an edge is the sum of its label and the labels of its...... two endvertices. We define χ (G) to be the smallest integer k for which G has an edge-colouring total k-labelling. This parameter has natural upper and lower bounds in terms of the maximum degree Δ of G : ⌈ (Δ + 1) / 2 ⌉ ≤ χ (G) ≤ Δ + 1. We improve the upper bound by 1 for every graph and prove χ (G...

To be aware of the health condition of the biological material in a fish farm allows us to establish the preventive measures required to prevent spreading of a disease and the treatment to be applied in case that a mass disease occurs. The level of the total protein in serum is, first of all, a synthetically indicator of the nutritional condition of the organism, presenting, at the same time, ample qualitative and quantitative variations depending on species, age, sex, stage of sexual maturity, water temperature and especially in correlation with the health condition of fish.

    From 1972 to 1978, six total sternectomies for malignant disease of the sternum were carried out. The clinical data are summarized and the surgical technique is described. After sternectomy, the area of chest wall resection was repaired by suturing a sheet of silicone rubber to the edges of the defect and chest wall stability was assured by using one or two stainless steel struts. Finally the defect was covered with methylmethacrylate prepared and applied inthe operative field. The prosthetic material was shaped until curing by polymerization was complete. We discuss the advantages of this type of reconstruction, the technical details, the use of antibiotics, the surgical drainage, and the need for biopsy prior to carrying out a total sternectomy.

    We discuss properties of distributions that are multivariate totally positive of order two (MTP2) related to conditional independence. In particular, we show that any independence model generated by an MTP2 distribution is a compositional semigraphoid which is upward-stable and singleton-transitive. In addition, we prove that any MTP2 distribution satisfying an appropriate support condition is faithful to its concentration graph. Finally, we analyze factorization properties of MTP2 distributi...

    An enantioselective total synthesis of (-)-galiellalactone has been accomplished. The key features of the synthesis involve the highly stereoselective construction of the cis-trisubstituted cyclopentane intermediate by a Pd(0)-catalyzed cyclization, the stereospecific introduction of an angular hydroxyl group by Riley oxidation, and the efficient construction of the tricyclic system of (-)-galiellalactone via a combination of diastereoselective Hosomi-Sakurai crotylation and ring-closing metathesis (RCM).

  20. Arsenic entrapment by nanocrystals of Al-magnetite: The role of Al in crystal growth and As retention.

    The nature of As-Al-Fe co-precipitates aged for 120 days are investigated in detail by High Resolution Transmission Electron Microscopy (HRTEM), Scanning TEM (STEM), electron diffraction, Energy Dispersive X-Ray Spectroscopy (EDS), Electron Energy-Loss Spectroscopy (EELS), and Energy Filtered Transmission Electron Microscopy (EFTEM). The Al present in magnetite is shown to favour As incorporation (up to 1.10 wt%) relative to Al-free magnetite and Al-goethite, but As uptake by Al-magnetite decreases with increasing Al substitution (3.53-11.37 mol% Al). Arsenic-bearing magnetite and goethite mesocrystals (MCs) are formed by oriented aggregation (OA) of primary nanoparticles (NPs). Well-crystalline magnetite likely formed by Otswald ripening was predominant in the Al-free system. The As content in Al-goethite MCs (having approximately 13% substituted Al) was close to the EDS detection limit (0.1 wt% As), but was below detection in Al-goethites with 23.00-32.19 mol% Al. Our results show for the first time the capacity of Al-magnetite to incorporate more As than Al-free magnetite, and the role of Al in favouring OA-based crystal growth under the experimental conditions, and therefore As retention in the formed MCs. The proposed mechanism of As incorporation involves adsorption of As onto the newly formed NPs. Arsenic is then trapped in the MCs as they grow by self-assembly OA upon attachment of the NPs. We conclude that Al may diffuse to the crystal faces with high surface energy to reduce the total energy of the system during the attachment events, thus favouring the oriented aggregation.

  1. BERKELEY: ALS ring

    International Nuclear Information System (INIS)

    Everybody at Lawrence Berkeley Laboratory's Center for Beam Physics is pleased with the rapid progress in commissioning LBL's Advanced Light Source (ALS) electron storage ring, the foundation for this third-generation synchrotron radiation facility. Designed for a maximum current of 400 mA, the ALS storage ring reached 407 mA just 24 days after storing the first beam on 16 March. ALS construction as a US Department of Energy (DOE) national user facility to provide high-brightness vacuum ultra-violet and soft x-ray radiation began in October 1987. One technical requirement marking project completion was to accumulate a 50-mA current in the storage ring. The ALS passed this milestone on 24 March, a week ahead of the official deadline. Once injected, the electron beam decays quasi-exponentially primarily because of interactions with residual gas molecules in the storage-ring vacuum chamber. Eventually, when the pressure in the vacuum chamber with beam decreases toward the expected operating level of 1 nano Torr, it will only be necessary to refill the storage ring at intervals of four to eight hours. At present the vacuum is improving rapidly as surfaces are irradiated (scrubbed) by the synchrotron radiation itself. At 100 mA, beam lifetime was about one hour (9 April)

Se estimó el GER con las siguientes ecuaciones: Harris-Benedict con peso real y peso ajustado, Ireton-Jones, Estimación Rápida de Carrasco (16,2 kcal × kg peso real y Mifflin. Resultados: (x ± de. El GER medido fue 1.797 ± 239 kcal/día. Todas las fórmulas, excepto Harris-Benedict con peso ajustado, sobreestimaron el gasto energético; la ecuación de Ireton-Jones fue la que sobreestimó en mayor cuantía el GER (689 ± 329 kcal/día, mientras que la ecuación de Mifflin sobreestimó el GER sólo en 6 ± 202 kcal/día. No se encontraron diferencias significativas entre el GER medido y el GER estimado por Mifflin y Estimación Rápida. La ecuación de Mifflin fue la más exacta: en 68% de los casos la diferencia entre el GER estimado y medido estuvo dentro de ± 10%, seguida por Harris-Benedict con peso real (64% y la Estimación Rápida (61%. Según el análisis de Bland-Altman, hubo una correlación significativa entre la diferencia GER estimado-medido y el promedio de GER estimado y medido con todas las ecuaciones, excepto con la Estimación Rápida de Carrasco. Esto implica que, con la excepción de esta última, las fórmulas estudiadas subestiman o sobrestiman el GER dependiendo de la magnitud del GER medido.

  5. Exact solution of the totally asymmetric Oslo model

    International Nuclear Information System (INIS)

    Recently it has been found (Pruessner G and Jensen H J 2003 Phys. Rev. Lett. 91 244303) that a totally asymmetric variant of the Oslo model (Christensen K et al 1996 Phys. Rev. Lett. 77 107) represents the entire universality class of the Oslo model with anisotropy. The totally asymmetric model can be solved without scaling assumptions by finding recursively the eigenvectors of the Markov matrix, which can be suitably modified to produce the moment generating function of the relevant observable. This method should be applicable to many other stochastic processes

  7. Diverticulosis in total colonic aganglionosis

    International Nuclear Information System (INIS)

    Two infants with total colonic aganglionosis (TCA) extending into the distal part of the ileum are described. Considerable diagnostic delay occurred with the correct diagnosis established first at 3 and 8 months, respectively. Radiologic findings compatible with TCA such as prolonged barium retention, reflux into ileum following barium enema, and foreshortening of colon were not clearly evident initially. Both patients demonstrated multiple acquired colon diverticula which increased both in number and size during the period of observation. These diverticula are probably a late manifestation of the spastic state of the anganglionic colon. Thus demonstration of diverticula supplies a strong evidence of TCA in infants with intestinal obstruction. (orig.)

    The ammosamides A-C are chlorinated pyrrolo[4,3,2-de]quinoline metabolites isolated from the marine-derived Streptomyces strain CNR-698. The natural products, which possess a dense array of heteroatoms, were synthesized in 17–19 steps from 4-chloroisatin. That the five nitrogen atoms were introduced at the appropriate time and in a suitable oxidation state was key to the success of the total synthesis. Compared to synthetic deschloro ammosamide B, natural ammosamide B is much less susceptible to oxidative degradation. PMID:20131899

    Full Text Available Companies have become very disillusioned with Total Quality Management (TQM as a solution to their quality related problems. Part of the problem has been that companies' expectations from TQM is as a solution to their existing problems rather than as a new philosophy towards creating value for shareholders, employees, and customers. Employee involvement is usually the element in the TQM philosophy that is most difficult to manage. Central to employee participation within the TQM philosophy is teamwork. In the attempt to facilitate total quality management, this article explores specific South African challenges to achieving this. These areaffirmative action and divers ity management skills shortages, training and development low levels of employee well-being. Working with people requires fundamental understanding of the uniqueness of each individual with their own identity and set of preferences. It also requires an understanding of teams and the mechanisms of making a group of individuals work well or poorly together. This will assist managers to realise active participation, quality output from their workers through individualised, and team based motivational processes.

    Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional incentives for P recovery emerge when accounting for the total value of P recovery. This article provides a comprehensive overview of the range of benefits of recovering P from waste streams, i.e., the total value of recovering P. This approach accounts for P products, as well as other assets that are associated with P and can be recovered in parallel, such as energy, nitrogen, metals and minerals, and water. Additionally, P recovery provides valuable services to society and the environment by protecting and improving environmental quality, enhancing efficiency of waste treatment facilities, and improving food security and social equity. The needs to make P recovery a reality are also discussed, including business models, bottlenecks, and policy and education strategies. PMID:27214029

  2. Total probabilities of ensemble runoff forecasts

    Olav Skøien, Jon; Bogner, Konrad; Salamon, Peter; Smith, Paul; Pappenberger, Florian

    2016-04-01

    Ensemble forecasting has for a long time been used as a method in meteorological modelling to indicate the uncertainty of the forecasts. However, as the ensembles often exhibit both bias and dispersion errors, it is necessary to calibrate and post-process them. Two of the most common methods for this are Bayesian Model Averaging (Raftery et al., 2005) and Ensemble Model Output Statistics (EMOS) (Gneiting et al., 2005). There are also methods for regionalizing these methods (Berrocal et al., 2007) and for incorporating the correlation between lead times (Hemri et al., 2013). Engeland and Steinsland Engeland and Steinsland (2014) developed a framework which can estimate post-processing parameters which are different in space and time, but still can give a spatially and temporally consistent output. However, their method is computationally complex for our larger number of stations, and cannot directly be regionalized in the way we would like, so we suggest a different path below. The target of our work is to create a mean forecast with uncertainty bounds for a large number of locations in the framework of the European Flood Awareness System (EFAS - http://www.efas.eu) We are therefore more interested in improving the forecast skill for high-flows rather than the forecast skill of lower runoff levels. EFAS uses a combination of ensemble forecasts and deterministic forecasts from different forecasters to force a distributed hydrologic model and to compute runoff ensembles for each river pixel within the model domain. Instead of showing the mean and the variability of each forecast ensemble individually, we will now post-process all model outputs to find a total probability, the post-processed mean and uncertainty of all ensembles. The post-processing parameters are first calibrated for each calibration location, but assuring that they have some spatial correlation, by adding a spatial penalty in the calibration process. This can in some cases have a slight negative

  3. Mechanical Properties and Microstructure of Neutron Irradiated Cold-worked Al-1050 and Al-6063 Alloys

    International Nuclear Information System (INIS)

    The impact of neutron irradiation on the internal microstructure, mechanical properties and fracture morphology of cold-worked Al-1050 and Al-6063 alloys was studied, using scanning and transmission electron microscopy, and tensile measurements. Specimens consisting of 50 mm long and 6 mm wide gauge sections, were punched out from Al-1050 and Al-6063 23% cold-worked tubes. They were exposed to prolonged neutron irradiation of up to 4.5x1025 and 8x1025 thermal neutrons/m2 (E -3 s-1. In general, the uniform and total elongation, the yield stress, and the ultimate tensile strength increase as functions of fluence. However, for Al-1050 a decrease in the ultimate tensile strength and yield stress was observed up to a fluence of 1x1025 thermal neutrons/m2 which then increase with thermal neutrons fluence. Metallographic examination and fractography for Al-6063 revealed a decrease in the local area reduction of the final fracture necking. This reduction is accompanied by a morphology transition from ductile transgranular shear rupture to a combination of transgranular shear with intergranular dimpled rupture. The intergranular rupture area increases with fluence. In contrast, for Al-1050, fracture morphology remains ductile transgranular shear rupture and the final local area reduction remains almost constant No voids could be observed in either alloy up to the maximum fluence. The dislocation density of cold-worked Al was found to decrease with the thermal neutron fluence. Prolonged annealing of unirradiated cold-worked Al-6063 at 52 degree led to similar results. Thus, it appears that, under our irradiation conditions, whereby the temperature encompassing the samples increases the exposure to this thermal field is the major factor influencing the mechanical properties and microstructure of aluminum alloys

  7. Complications after total hip replacement

    International Nuclear Information System (INIS)

    Complications seen after long-term follow-up examinations of total hip replacement should be treated immediately and completely. In the past decade a considerable increase in revisions has been noted. Radiographic assessment may be regarded as an effective means in diagnosing prosthetic complications from the surgeon's point of view. Examples are given. The difficulties in radiographic assessment of complications after cementless implanation or cemented prostheses without contrast media are mentioned. Prosthesis-related complications, such as mechanical loosening, infection with and without loosening, fatigue fractures and wear, fractures of the femur or pelvis, dislocations and surgical failures, are illustrated, as are clinical courses with gross loss of bone stock after repeated surgery and delayed revisions. Complications not related to the prosthesis such as periarticular ossification, muscle deficiencies, and nervous and vascular lesions are also explained using examples. (orig.)

  8. A total safety management model

    International Nuclear Information System (INIS)

    In nuclear organizations, quality and safety are inextricably linked. Therefore, the search for excellence means reaching excellence in nuclear safety. The International Atomic Energy Agency, IAEA, developed, after the Chernobyl accident, the organizational approach for improving nuclear safety based on the safety culture, which requires a framework necessary to provide modifications in personnel attitudes and behaviors in situations related to safety. This work presents a Total Safety Management Model, based on the Model of Excellence of the Brazilian Quality Award and on the safety culture approach, which represents an alternative to this framework. The Model is currently under validation at the Nuclear Engineering Institute, in Rio de Janeiro, Brazil, and the results of its initial safety culture self assessment are also presented and discussed.

    Full Text Available On the basis of empirical experience from practical work this paper discusses the real place and role of the sociologist in the prison, as a total institution, where sociologists are employed as educators, along with other professions (psychologists, educationalists, social workers, etc., and usually closely cooperating with lawyers. According to the current work regulations, and on the basis of practice so far, the sociologist can work as classical educator, to be in charge of educational groups of inmates, work in the reception department on assessing incoming inmates, and to organize inmates' leisure time by directing them towards pro-social and creative activities (music, painting, reading, etc.. New reform trends in working with inmates suggest new work methods, such as creative workshops, counselling in the sphere of substance abuse and dependency, or expert teams in working with minors. In the prison, the sociologist is indispensable as a researcher of criminal activities.

  10. Total quality management implementation guidelines

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-01

    These Guidelines were designed by the Energy Quality Council to help managers and supervisors in the Department of Energy Complex bring Total Quality Management to their organizations. Because the Department is composed of a rich mixture of diverse organizations, each with its own distinctive culture and quality history, these Guidelines are intended to be adapted by users to meet the particular needs of their organizations. For example, for organizations that are well along on their quality journeys and may already have achieved quality results, these Guidelines will provide a consistent methodology and terminology reference to foster their alignment with the overall Energy quality initiative. For organizations that are just beginning their quality journeys, these Guidelines will serve as a startup manual on quality principles applied in the Energy context.

  11. Total quality management program planning

    1994-05-01

    As government funding grows scarce, competition between the national laboratories is increasing dramatically. In this era of tougher competition, there is no for resistance to change. There must instead be a uniform commitment to improving the overall quality of our products (research and technology) and an increased focus on our customers` needs. There has been an ongoing effort to bring the principles of total quality management (TQM) to all Energy Systems employees to help them better prepare for future changes while responding to the pressures on federal budgets. The need exists for instituting a vigorous program of education and training to an understanding of the techniques needed to improve and initiate a change in organizational culture. The TQM facilitator is responsible for educating the work force on the benefits of self-managed work teams, designing a program of instruction for implementation, and thus getting TQM off the ground at the worker and first-line supervisory levels so that the benefits can flow back up. This program plan presents a conceptual model for TQM in the form of a hot air balloon. In this model, there are numerous factors which can individually and collectively impede the progress of TQM within the division and the Laboratory. When these factors are addressed and corrected, the benefits of TQM become more visible. As this occurs, it is hoped that workers and management alike will grasp the ``total quality`` concept as an acceptable agent for change and continual improvement. TQM can then rise to the occasion and take its rightful place as an integral and valid step in the Laboratory`s formula for survival.

  12. Dosimetry of total body irradiation

    International Nuclear Information System (INIS)

    In the treatment of disseminated malignancies an improvement in the curability and reduction of complication rates require high precision total body irradiation (TBI) and correct reporting of relevant treatment parameters. Optimal TBI dosimetry is the basis. Radiooncological and radiobiological requirements as well as the special physical situation have to be considered. To review the efforts of medical physicists, highlights from TBI workshops and publications are summarized. Additionally, dosimetric data from 34 European radiooncological centres contributing to the recent ESTRO inquiry on TBI are analysed. The topics are: absorbed dose and dose monitor calibration, determination of absolute and relative doses, dose ratios, attenuation data and heterogeneity corrections; TBI dose calculation methods regarding patient position, beam incidence, body shape and thickness, lung size and density; methods of TBI treatment planning including calculated dose modification and of TBI quality assurance. In conclusion, the following recommendations can be given: TBI dosimetry shall be performed under TBI conditions, close to the real treatment situation. The absorbed dose to water must be determined. The dose monitor should be calibrated against dose measurements at the centre of a water equivalent phantom of TBI equivalent size and typical thickness. Photon fluence profiles have to be measured with small phantoms. Influences on the local dose must be investigated systematically. A reproducible AP/PA TBI technique should be used. The TBI dose shall be specified to mid-abdomen and reported in units of gray. The single and total dose and the dose rate to the lungs, the number of fractions and the treatment time schedule must be stated. In vivo dosimetry is required if non-reliable TBI techniques are used. An international TBI dosimetry intercomparison could assist these efforts to improve the treatment of acute leukaemia.

    Biodiesel is the common name for fatty acid methyl esters, obtained by esterification (basic catalysis) or trans-esterification (acid catalysis) of vegetable or animal oils with alcohols, and used as liquid fuel. Production involves the reaction, under mild conditions, between the oil and, typically, excess of methanol. Traditional production of biodiesel exhibits some handicaps, such as the shift of equilibrium to fatty acids by using excess of alcohol that must be separated and recycled. As alternative, it is possible to integrate reaction/separation operations into a single intensified unit, a reactive distillation column, followed by a second separation unit. These configurations exhibit several advantages such as shifting equilibrium in the reactive region and, because of the thermal integration with the second unit, energy savings during products separation. In order to design these production sequences taking advantage of steady state knowledge (energy savings) and considering dynamic performance, this work performs a controllability analysis for six possible configurations; open-loop control properties, evaluated by single value decomposition, are probed by implementing PI controllers to the system. The reactive distillation column coupled to a stripper, without reboilers, shows to be the best option in terms of closed-loop performance and energy savings. [Spanish] Biodiesel es el nombre comun dado a metil esteres de acidos grasos obtenidos por esterificacion (catalisis basica) o trans-esterificacion (catalisis acida) de aceites animales o vegetales con alcoholes, y usados como combustibles liquidos. Su produccion involucra la reaccion entre el aceite y, tipicamente, exceso de metanol a condiciones moderadas. La produccion tradicional de biodiesel exhibe algunas desventajas como el desplazamiento del equilibrio hacia acidos grasos debido al exceso de alcohol, que debe ser separado y reciclado. Alternativamente, es posible integrar las operaciones reaccion

  17. Hypermnesia and total retrieval time.

    Science.gov (United States)

    Mulligan, Neil W

    2006-05-01

    Recall performance sometimes improves over repeated recall attempts, a phenomenon dubbed hypermnesia. A critical theoretical issue is whether hypermnesia is due to repeated testing per se or increased retrieval time. The present experiments investigated by contrasting five testing conditions. All participants were presented with the same study list followed by either two shorter recall tests or a single longer test. In the multiple test conditions, the tests were either separated by a (filled) 7-minute interval (the multiple-split condition), or presented consecutively, with no break (the multiple-immediate condition). In the single test conditions, the test either began at the start of the recall session, after a (filled) 7-minute delay, or with a 7-minute interruption inserted in the middle. The multiple-split condition produced more reminiscence and hypermnesia than the multiple-immediate condition. More importantly, the multiple-split condition produced greater cumulative recall than any of the other conditions (which did not differ among themselves). That is, single and repeated recall tests of equal total duration are not functionally equivalent. PMID:16766451

    Full Text Available La Enfermedad de Parkinson (EP es un proceso neurodegenerativo de presentación esporádica. Fue descrita por James Parkinson en 1817. De causa multifactorial, siendo los principales factores etiológicos de naturaleza genética y ambiental. Hasta el momento sólo se dispone de "tratamiento paliativo" mediante medicamentos como la levodopa, la cual restaura los niveles de dopamina cerebral y pueden mejorar los síntomas por un tiempo. Como factores responsables directos de la pobre calidad de vida de los pacientes parkinsonianos están los síntomas no motores, variados, frecuentes y de impacto infravalorado. Los enfermos son propensas a la pérdida de peso y la desnutrición. Los movimientos involuntarios resultan en un gasto de energía creciente y los síntomas de la enfermedad como los efectos secundarios del tratamiento pueden limitar el consumo de alimentos. Es necesaria una atención integral para minimizar sus limitaciones y mejorar así su calidad de vida y la de su familia. Dentro de una atención integral, el aspecto de la alimentación-nutrición es cardinal por lo que se ofrece aquí un protocolo de trabajo para la intervención nutricional al enfermo de Parkinson

  1. Total allowable concentrations of monomeric inorganic aluminum and hydrated aluminum silicates in drinking water.

    Maximum contaminant levels are used to control potential health hazards posed by chemicals in drinking water, but no primary national or international limits for aluminum (Al) have been adopted. Given the differences in toxicological profiles, the present evaluation derives total allowable concentrations for certain water-soluble inorganic Al compounds (including chloride, hydroxide, oxide, phosphate and sulfate) and for the hydrated Al silicates (including attapulgite, bentonite/montmorillonite, illite, kaolinite) in drinking water. The chemistry, toxicology and clinical experience with Al materials are extensive and depend upon the particular physical and chemical form. In general, the water solubility of the monomeric Al materials depends on pH and their water solubility and gastrointestinal bioavailability are much greater than that of the hydrated Al silicates. Other than Al-containing antacids and buffered aspirin, food is the primary source of Al exposure for most healthy people. Systemic uptake of Al after ingestion of the monomeric salts is somewhat greater from drinking water (0.28%) than from food (0.1%). Once absorbed, Al accumulates in bone, brain, liver and kidney, with bone as the major site for Al deposition in humans. Oral Al hydroxide is used routinely to bind phosphate salts in the gut to control hyperphosphatemia in people with compromised renal function. Signs of chronic Al toxicity in the musculoskeletal system include a vitamin D-resistant osteomalacia (deranged membranous bone formation characterized by accumulation of the osteoid matrix and reduced mineralization, reduced numbers of osteoblasts and osteoclasts, decreased lamellar and osteoid bands with elevated Al concentrations) presenting as bone pain and proximal myopathy. Aluminum-induced bone disease can progress to stress fractures of the ribs, femur, vertebrae, humerus and metatarsals. Serum Al ≥100 µg/L has a 75-88% positive predictive value for Al bone disease.

  5. Characterization and formation mechanism of laser-welded Mg and Al alloys using Ti interlayer

    International Nuclear Information System (INIS)

    Ti was used as an interlayer to join Mg and Al alloys by fiber laser welding. The formation of Mg–Al intermetallic compounds could be totally suppressed and the interfacial layer was composed of Al3Ti and small amounts of Al18Ti2Mg3. The mechanism of interfacial layer formation was attributed to the thermodynamic behavior of the formation of intermetallic compounds in Al–Mg–Ti ternary system and to precise control of the laser power.

    Full Text Available Water column data of carbon and carbon relevant hydrographic and hydrochemical parameters from 188 previously non-publicly available cruises in the Arctic, Atlantic, and Southern Ocean have been retrieved and merged into a new database: CARINA (CARbon IN the Atlantic. The data have been subject to rigorous quality control (QC in order to ensure highest possible quality and consistency. The data for most of the parameters included were examined in order to quantify systematic biases in the reported values, i.e. secondary quality control. Significant biases have been corrected for in the data products, i.e. the three merged files with measured, calculated and interpolated values for each of the three CARINA regions; the Arctic Mediterranean Seas (AMS, the Atlantic (ATL and the Southern Ocean (SO. With the adjustments the CARINA database is consistent both internally as well as with GLODAP (Key et al., 2004 and is suitable for accurate assessments of, for example, oceanic carbon inventories and uptake rates and for model validation. The Arctic Mediterranean Seas includes the Arctic Ocean and the Nordic Seas, and the quality control was carried out separately in these two areas. This contribution presents an account of the quality control of the total alkalinity (ALK data from the Nordic Seas in CARINA. Out of the 35 cruises from the Nordic Seas included in CARINA, 21 had ALK data. The data from 6 of these were found to be of low quality and should not be used. Of the others, 3 were found to be biased low and were subject to adjustment. Thus the final CARINA data product contains ALK data from 15 cruises from the Nordic Seas, and these data appear consistent to ±3 μmol kg−1.

  7. Precipitation in cold-rolled Al-Sc-Zr and Al-Mn-Sc-Zr alloys prepared by powder metallurgy

    Vlach, Martin

    2013-12-01

    The effects of cold-rolling on thermal, mechanical and electrical properties, microstructure and recrystallization behaviour of the AlScZr and AlMnScZr alloys prepared by powder metallurgy were studied. The powder was produced by atomising in argon with 1% oxygen and then consolidated by hot extrusion at 350 C. The electrical resistometry and microhardness together with differential scanning calorimetry measurements were compared with microstructure development observed by transmission and scanning electron microscopy, X-ray diffraction and electron backscatter diffraction. Fine (sub)grain structure developed and fine coherent Al3Sc and/or Al3(Sc,Zr) particles precipitated during extrusion at 350 C in the alloys studied. Additional precipitation of the Al3Sc and/or Al3(Sc,Zr) particles and/or their coarsening was slightly facilitated by the previous cold rolling. The presence of Sc,Zr-containing particles has a significant antirecrystallization effect that prevents recrystallization at temperatures minimally up to 420 C. The precipitation of the Al6Mn- and/or Al 6(Mn,Fe) particles of a size ~ 1.0 μm at subgrain boundaries has also an essential antirecrystallization effect and totally suppresses recrystallization during 32 h long annealing at 550 C. The texture development of the alloys seems to be affected by high solid solution strengthening by Mn. The precipitation of the Mn-containing alloy is highly enhanced by a cold rolling. The apparent activation energy of the Al3Sc particles formation and/or coarsening and that of the Al6Mn and/or Al 6(Mn,Fe) particle precipitation in the powder and in the compacted alloys were determined. The cold deformation has no effect on the apparent activation energy values of the Al3Sc-phase and the Al 6Mn-phase precipitation. © 2013 Elsevier Inc.

    The production of K$^+$, K$^-$ and $\\varphi$(1020) mesons is studied in Al+Al collisions at beam energy of 1.9A GeV which is close or below the production threshold in NN reactions. Inverse slopes, anisotropy parameters, and total emission yields of K$^{\\pm}$ mesons are obtained. A comparison of the ratio of kinetic energy distributions of K$^-$ and K$^+$ mesons to the HSD transport model calculations suggests that the inclusion of in-medium modifications of kaon properties is necessary to reproduce the ratio. The inverse slope and total yield of $\\phi$ mesons are deduced. The contribution to K$^-$ production from $\\phi$ meson decays is found to be [17 $\\pm$ 3 (stat) $^{+2}_{-7}$ (syst)] %. The results are in line with previous K$^{\\pm}$ and $\\phi$ data obtained for different colliding systems at similar incident beam energies.

    Full Text Available Objective. The aim of this study was to assess iron status in a cohort of amyotrophic lateral sclerosis (ALS patients compared to controls in order to evaluate these parameters as a risk factor or a modifying factor of ALS. Methods. We collected serum iron, ferritin, transferrin, total iron-binding capacity, and transferrin saturation coefficient (TSC from 104 ALS patients at the time of diagnosis and from 145 controls. We reported phenotypic characteristics and evolution parameters such as ALSFRS-R and forced vital capacity at diagnosis and after one year of follow-up. In a first step we compared iron status between ALS patients and controls, and then we evaluated the relation between iron status and disease evolution of ALS patients using univariate and multivariate analysis. Results. We observed increased concentrations of serum iron (P=0.002 and ferritin (P<0.0001 and increased TSC (P=0.017 in ALS patients. We also showed an association between markers of iron status and high body weight loss in ALS patients. The multivariate analysis of survival highlighted a significant relation between ferritin level and disease duration (P=0.038. Conclusion. This is the first study showing a higher concentration of serum iron in ALS patients, strengthening the involvement of a deregulation of iron metabolism in ALS.

Nesse contexto, a atividade física pode contribuir com um efeito duplo, por meio de mudanças fisiológicas agudas e crônicas: na primeira condição encontra-se o gasto energético do exercício e recuperação (EPOC - consumo excessivo de oxigênio após o exercício, e na segunda encontra-se a taxa metabólica de repouso (TMR. Dessa forma, o objetivo deste trabalho de revisão foi investigar o efeito do EPOC e da TMR como coadjuvantes nos programas de emagrecimento, buscando discutir os divergentes resultados encontrados na literatura, no que diz respeito à magnitude e duração do EPOC, bem como discutir o efeito do exercício na TMR. Os estudos demonstram, de forma geral, que o exercício de maior intensidade é capaz de promover maior EPOC, se comparado com um exercício de intensidade menor e, quando comparam o exercício resistido com o aeróbio, verifica-se maior EPOC no primeiro. Em relação às alterações da TMR, os resultados agudos mostram aumento significativo, porém os resultados em longo prazo são mais discrepantes, devido à dificuldade de mensurar essa variável, sem superestimá-la. Concluindo, a literatura aponta que a periodização de um treinamento que possa maximizar tanto o EPOC quanto a TMR podem ser importantes fatores para o emagrecimento e, embora, o custo energético dessas variáveis em uma sessão de exercício se mostre pequeno, em longo prazo poderá ser bastante significativo. No entanto, novos estudos deverão ser realizados com o intuito de confirmar essas evidências.La creciente prevalencia de la obesidad y el sobrepeso resalta la necesidad de intervenciones para reverter ese cuadro.

    International Nuclear Information System (INIS)

    Purpose: To evaluate the prognostic factors and the ophthalmologic follow-up on cataract formation following total body irradiation (TBI) prior to bone marrow transplantation (BMT). Methods and Materials: Between 1980 and 1992, 494 patients were referred to our department for TBI prior to BMT. The mean age was 32 ± 11 (median: 32, range: 2-63) years and the male to female ratio was 1.6 (304:190). The majority of patients were treated for acute leukemia (lymphoblastic, n = 177, 36%; or nonlymphoblastic, n = 139, 28%); 80 (16%) for chronic myeloid leukemia, 60 (12%) for non-Hodgkin's lymphoma, 23 (5%) for multiple myeloma, and 15 (3%) for other malignancies. Two hundred and fifty-four (51%) patients were grafted in the first complete remission (CR), 118 (24%) in second CR. Allogeneic BMT was performed in 210 (43%) patients, and autologous BMT in 284 (57%). Methotrexate combined to steroids (n = 47, 22%) or to cyclosporine (n = 163, 78%) was administered for graft-versus-host disease (GvHD) prophylaxis. In 188 patients (38%), heparin was used in the prevention of veno-occlusive disease (VOD) of the liver. Furthermore, steroid administration was registered in 223 patients (45%). The conditioning chemotherapy consisted of cyclophosphamide (Cy) alone in 332 (67%) patients. Total-body irradiation was administered either in single dose (STBI; 10 Gy in 1 day, n = 291) or in six fractions (FTBI; 12 Gy over 3 consecutive days, n = 203) before BMT. The mean instantaneous dose rate was 0.0574 ± 0.0289 Gy/min (0.024-0.1783). It was < 0.048 Gy/min in 157 patients (LOW group), ≥ 0.048 Gy/min and < 0.09 Gy/min in 301 patients (MEDIUM group), and ≥ 0.09 Gy/min in 36 patients (HIGH group). Results: When considering all patients, 42 (8.5%) patients developed cataracts after 13 to 72 months (median: 42 months) with a 5-year estimated cataract incidence (ECI) of 23%. Thirty-three (11.3%) out of 291 patients in the STBI group, and 9 (4.4%) out of 203 patients in the FTBI group

    Full Text Available Swine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity (EC of the medium, Chemical Oxygen Demand (COD loading rates and catalytic activity of the electrodes used. In this research, a study was conducted to compare the pollutant removal efficiencies of three electrodes (Fe-Fe, Al-Al and Fe-Al with three electric current levels (500, 1000 and 2000 mA while treating swine manure effluents. The electrochemical cell consisted of two parallel rectangular plates (90×25×1.5 mm of Iron (Fe-Fe, Aluminum (Al-Al and Iron-Aluminum (Fe-Al, later on described as hybrid electrodes; immersed in a beaker with 550 mL swine effluents and powered by a Direct Current (DC supply. All studies were conducted in batches at room temperature. In general, removal efficiencies were increased with increasing current densities and electrolysis times for electrodes evaluated. Aluminum electrodes outperformed iron and hybrid (iron-aluminum electrodes in removing Total Phosphorus (TP at all current density levels tested. Overall, use of hybrid electrodes resulted in better COD removal. For the same treatment times (1200 s at higher current density (21 mA cm-2, hybrid electrodes removed about 100% COD, which are about 1.9 and 1.3 times higher than those of aluminum and iron electrodes, respectively. Iron electrodes showed the highest removal efficiency (85% for Total Organic Carbon (TOC at 21 mA cm-2 current density and 1200 s treatment time. Overall, lower Specific Electrical Energy Consumptions (SEECs per kg of Pollutants (TP, COD and TOC were estimated for the aluminum

  15. Growth of Fe2Al5 phase on pure iron hot-dipped in Al-Mg-Si alloy melt with Fe in solution

    International Nuclear Information System (INIS)

    We have examined the growth and morphology of the Fe-Al alloy layer (Fe2Al5-η and FeAl3-θ phases) on pure Fe sheets hot-dipped at 750°C in an Al-8.2Mg-4.8Si-Fe (wt.%) and Al-Fe alloy melts which are saturated with Fe where the effect of Fe dissolution from the solid Fe can be eliminated. In both the Al-Mg-Si-Fe and Al-Fe melts, the total thickness of Fe sheets increased during the dipping, indicating that the diffusion of Al from the melt side is dominant in the growth of the Fe-Al alloy layer. The growth rate constant of the η phase layer in the both melts was close to 0.5 while the growth rate in the Al-Mg-Si-Fe alloy melt was approximately one order of magnitude slower than that in the Al-Fe melt. The θ phase layer appeared continuous in the Al-Mg-Si-Fe alloy melt, whereas the layer was discontinuous in the Al-Fe melt. The sluggish growth of the η phase layer in the Al-Mg-Si-Fe alloy melt is discussed. (author)

    Die vorliegende Arbeit beschäftigt sich mit der Synthese und den Eigenschaften von doppelthydrophilen Blockcopolymeren und ihrer Anwendung in einem biomimetischen Mineralisationsprozeß von Calciumcarbonat und Bariumsulfat. Doppelthydrophile Blockcopolymere bestehen aus einem hydrophilen Block, der nicht mit Mineralien wechselwirkt und einem zweiten Polyelektrolyt-Block, der stark mit Mineraloberflächen wechselwirkt. Diese Blockcopolymere wurden durch ringöffnende Polymerisation von N-carboxyanhydriden (NCA's) und a-methoxy-ω-amino[poly(ethylene glycol)] PEG-NH2 als Initiator hergestellt. Die hergestellten Blockcopolymere wurden als effektive Wachstumsmodifikatoren für die Kristallisation von Calciumcarbonat und Bariumsulfat Mineralien eingesetzt. Die so erhaltenen Mineralpartikel (Kugeln, Hantel, eiförmige Partikel) wurden durch Lichtmikroskopie in Lösung, SEM und TEM charakterisiert. Röntgenweitwinkelstreuung (WAXS) wurde verwendet, um die Modifikation von Calciumcarbonat zu ermitteln und die Größe der Calciumcarbonat- und Bariumsulfat-Nanopartikel zu ermitteln. This work describes the synthesis and characterization of double hydrophilic block copolymers and their use in a biomimetic mineralization process of Calcium Carbonate and Barium Sulfate. Double hydrophilic block copolymers consist of a hydrophilic block that does not interact with minerals and another hydrophilic polyelectrolyte block that strongly interacts with mineral surfaces. These polymers were synthesised via ring opening polymerisation of N-carboxyanhydride (NCA), and the first hydrophilic block a-methoxy-ω-amino[poly(ethylene glycol)] PEG-NH2 was used as an initiator. The prepared block copolymers were used as effective crystal growth modifiers to control the crystallization of Calcium Carbonate and Barium Sulfate minerals. The resulting mineral particles (spheres, dumbbells, egg-like particles) were characterised by light microscopy in solution, by SEM, and by TEM. X-Ray scattering

    Using first-principles molecular dynamics (FPMD) and total-energy calculations, we demonstrate low-barrier bulk diffusion of Al-bearing species in γ-NaAlH4, a recently proposed high-entropy polymorph of NaAlH4. For charged AlH4– and neutral AlH3 vacancies, the computed barriers for diffusion are <0.1 eV, and we directly observe the predicted diffusive pathways in FPMD simulations at picosecond time scales. In contrast, such diffusion in the α phase is inaccessible to FPMD, consistent with much higher barriers. The transport behavior of γ-NaAlH4, in addition to key dynamical and structural signatures, is consistent with experimental observations of high-mobility species, strongly supporting the idea that an intermediate transition from the α phase to a high-entropy polymorph facilitates the hydrogen-releasing decomposition of NaAlH4. Our results provide an answer to longstanding questions regarding the responsible agent for the experimentally observed efficient Al transport during dehydrogenation and suggest that mass transport and phase transformation kinetics are coupled. Implications for understanding the (de)hydrogenation of undoped and catalyzed NaAlH4 are discussed.

    Recently, Li et al. (Phys. Rev. Lett., 104 (2010) 018701) studied a spatial network which is constructed from a regular lattice by adding long-range edges (shortcuts) with probability Pij~rij−α, where rij is the Manhattan length of the long-range edges. The total length of the additional edges is subject to a cost constraint (∑ r = C). This spatial network model displays an optimal exponent α for transportation (measured by the average shortest-path length). However, we observe that the degre...

  3. In situ synchrotron X-ray diffraction study on the improved dehydrogenation performance of NaAlH4–Mg(AlH4)2 mixture

    International Nuclear Information System (INIS)

    Highlights: •The dehydrogenation reactions of NaAlH4–Mg(AlH4)2 mixture were explored by in situ XRD. •NaAlH4–Mg(AlH4)2 mixture exhibited multiple-step dehydrogenation processes. •The mutual catalytic roles of NaAlH4 and Mg(AlH4)2 in the mixture were investigated. •NaAlH4–Mg(AlH4)2 mixture release 5.35 wt% H2 at an initial temperature of 120 °C. -- Abstract: The dehydrogenation performance and mechanism of the synthesized NaAlH4–Mg(AlH4)2 powders were investigated by performing thermogravimetric analysis and in situ synchrotron X-ray diffraction analysis. NaAlH4 not only facilitates the first step dehydrogenation of Mg(AlH4)2 in lowering its initial dehydrogenation temperature but also increases the total amount of H2 released. Besides, MgH2 and/or Al phases, the products of the first step dehydrogenation reaction, play a catalytic role in lowering the initial dehydrogenation temperature of NaAlH4. The synthesized NaAlH4–Mg(AlH4)2 mixture has an initial dehydrogenation temperature as low as 120 °C, and is able to release 5.35 wt% H2 below 350 °C. The self-catalytic dehydrogenation behavior of the NaAlH4–Mg(AlH4)2 mixture was elaborated in this work with the aid of in situ synchrotron XRD

  5. The electronic structure of wurtzite and zincblende AlN: an ab initio comparative study

    International Nuclear Information System (INIS)

    This work deals with the electronic properties, in different crystal phases, of AlN (wurtzite and zincblende) compounds computed using an all electron ab initio linearized augmented plane wave method. Results include band structure, total and partial density of states, charge density and the ionicity factor. Most of the calculated band parameters, of direct bandgap, total- and upper-valence bandwidths and antisymmetric gap for wurtzite-AlN are close to those of c-AlN to within 1%. The charge distributions have similar features, meaning that AlN has the same ionicity factor in both structures. (author)

    This image of Alexandria was taken by astronauts on board the International Space Station in December 2000 using an Electronic Still Camera. A wider-angle view (STS088-739-90) taken from the Space Shuttle in December 1998 is available for context. Alexandria (Al Iskandariya) occupies a T-shaped peninsula and strip of land separating the Mediterranean from Lake Mariout. Originally the town was built upon a mole (stone breakwater) called Heptastadium, which joined the island of Pharos (see referenced website, below) to the mainland. Since then sedimentary deposits have widened the mole. Since 1905, when the 370,000 Alexandrians lived in an area of about 4 sq km between the two harbors, the city (population 4 million; see referenced website, below) has grown beyond its medieval walls and now occupies an area of about 300 sq km. The Mahmudiya Canal, connecting Alexandria with the Nile, runs to the south of the city and, by a series of locks, enters the harbor of the principal port of Egypt (note ships). The reddish and ochre polygons west of Lake Mariout are salt-evaporation, chemical-storage, and water-treatment ponds within the coastal lagoon.

  7. Undulators at the ALS

    International Nuclear Information System (INIS)

    At Lawrence Berkeley Laboratory's (LBL) Advanced Light Source (ALS), three 4.6 m long undulators have been completed, tested and installed. A fourth is under construction. The completed undulators include two 5.0 cm period length, 89 period devices (U5.0s) which achieve a 0.85 T effective field at a 14 mm minimum gap and a 8.0 cm period length, 55 period device (U8.0) that reaches a 1.2 T effective field at a 14 mm minimum gap. The undulator under construction is a 10.0 cm period length, 43 period device (U10.0) that is designed to achieve 0.98 T at a 23 mm gap. Undulator magnetic gap variation (rms) is within 25 microns over the periodic structure length. Reproducibility of the adjustable magnetic gap has been measured to be within +/- 5 microns. Gap adjusting range is from 14 mm to 210 mm, which can be scanned in one minute. The 5.1 m long vacuum chambers are flat in the vertical direction to within 0.74 mm and straight in the horizontal direction to within 0.08 mm over the 4.6 m magnetic structure sections. Vacuum chamber base pressures after UHV beam conditioning are. in the mid 10-11 Torr range and storage ring operating pressures with full current are in the low 10-10 Torr range. Measurements show that the uncorrelated magnetic field errors are 0.23%, and 0.20% for the two U5.Os and the U8.0 respectively and that the field integrals are small over the 1 cm by 6 cm beam aperture. Device description, fabrication, and measurements are presented

    2003-01-01

    The site preference of Zr atoms in Ti3Al and the phase stability of Ti2ZrAl are examined using first-principles electronic structure total energy calculations. Of the sixteen possible ways in which Ti, Zr and Al atoms can be arranged, in the lattice sites corresponding to $D0_{19}$ structure of Ti3Al, to obtain Ti2ZrAl, it is s hown that Zr atoms prefer to get substituted at the Ti sites. It is further shown that among the seven crystal structures considered, $D0_{19}$-like and $L1_2$-like are the competing ground-state structures of Ti2ZrAl. The above results are in agreement with the experimental results reported in the literature. Calculated values of equilibrium lattice parameters, heat of formation and bulk modulus of Ti2ZrAl are presented. The basis for the structural stability and bonding are analysed in terms of the density of states. Between the two possible 2-like structures, Ti2ZrAl shows enhanced stability for the one where Zr is substituted in the Ti sublattice, which again is in agreement with the experimental observation.

    Buckwheat (Fagopyrum esculentum Moench) is a species with high aluminum (Al) tolerance and accumulation. Although the physiological mechanisms for external and internal detoxification of Al have been well studied, the molecular mechanisms responsible are poorly understood. Here, we conducted a genome-wide transcriptome analysis of Al-responsive genes in the roots and leaves using RNA sequencing (RNA-Seq) technology. RNA-Seq generated reads ranging from 56×10(6) to 93×10(6). A total of 148,734 transcript contigs with an average length of 1,014 bp were assembled, generating 84,516 unigenes. Among them, 31,730 and 23,853 unigenes were annotated, respectively, in the NCBI plant database and TAIR database for Arabidopsis. Of the annotated genes, 4,067 genes in the roots and 2,663 genes in the leaves were up-regulated (>2-fold) by Al exposure, while 2,456 genes in the roots and 2,426 genes in the leaves were down-regulated (<2-fold) A few STOP1/ART1 (SENSITIVE TO PROTON RHIZOTOXICITY1/AL RESISTANCE TRANSCRIPTION FACTOR1)-regulated gene homologs including FeSTAR1, FeALS3 (ALUMINUM SENSITIVE3), FeALS1 (ALUMINUM SENSITIVE1), FeMATE1 and FeMATE2 (MULTIDRUG AND TOXIC COMPOUND EXTRUSION1 and 2) were also up-regulated in buckwheat, indicating some common Al tolerance mechanism across the species, although most STOP1/ART1-regulated gene homologs were not changed. Most genes involved in citric and oxalic acid biosynthesis were not significantly altered. Some transporter genes were highly expressed in the roots and leaves and responded to Al stress, implicating their role in Al tolerance and accumulation. Overall, our data provide a platform for further characterizing the functions of genes involved in Al tolerance and accumulation in buckwheat. PMID:25273892

    Full Text Available Increased prevalence of obesity is associated with the growth of chronic degenerative diseases. One of the main factors associated with this increase is the change in nutritional status of individuals. Medium chain triglycerides (MCT are rapidly metabolized and less stored in the adipose tissue, being a possible tool for weight control. In order to analyze the influence of consumption of this lipid on satiety, body composition and energy expenditure (EE, a literature review was performed of controlled clinical studies reported in PUBMED and ELSEVIER between the years 2000 and 2010. Fourteen articles were selected presenting short and long-term intervention. Among these, six showed a decrease in body mass of individuals, with consequent loss of weight. Only one showed a positive effect on satiation and four showed an increase in EE. Thus the results are inconclusive and there is a need for further controlled studies with standardized amounts of MCT, so that its use can become an alternative for obesity nutritional treatment.El aumento de la prevalencia de obesidad se asocia con el crecimiento de las enfermedades crónicas no transmisibles. Uno de los principales factores asociados a este aumento es el cambio en el estado nutricional de los individuos.

    The method defined by the IEC 60522 for determining the inherent filtration of an x-ray source device is applicable only for a limited range of tube voltage. Because the users cannot legally remove the x-ray movable diaphragm of the x-ray source device, total filtration, which is the sum of the additional filtration diaphragm movable for specific filtration and x-ray, cannot be measured. We develop a method for simply obtaining the total filtration for different tube voltage values. Total filtration can be estimated from a ratio R‧ of the air kerma Kx+T\\prime , which is measured with an Al plate with thickness T, and Kx\\prime measured without an Al plate. The conditions of the target material of the x-ray source device are then entered into the Report 78 Spectrum Processor to calculate the air kerma K x and K x+T for Al thicknesses x and (x  +  T), respectively, to obtain R. The minimum value of x, which is the difference between the R and R‧, is the total filtration of the x-ray source device. The total filtration calculated using the industrial x-ray source device was within  ±1% in the 40–120 kV range. This method can calculate the total filtration using air kerma measurements with and without the Al plate. Therefore, the load on the x-ray tube can be reduced, and preparation of multiple Al plates is not necessary. Furthermore, for the 40–120 kV tube voltage range, the user can easily measure the total filtration.

    Full Text Available Abstract : This article deals with some epistemological terms and theoretical postulates in the thought of a well known sufi  from the 9th century AD., Abu `Abdu’lLah Muhammad b. `Ali al-Hakim al-Tirmidzi, in order to describe the path (sulūk of a sufi towards the Ultimate Reality. In his own style thought about the sufis, placing an emphasis upon the strong relations between the walāyah (sufi  sainthood and the ma`rifa (sufi knowledge in the one side, and between the two a philosophy of Sufi Ethics. So, it is nothing out of the ordinary to fi nd his ethical inclinations as a dominant feature in every aspect of his epistemological thoughts. In addition, sufi epistemology in the perspective of philosophers focuses on enforcing the inner positive potents of the Self more so than to eliminate “the satanic influences” to the heart, because – in al-Tirmidzi’s argument is that the former would greatly improve the immunity of the self, and encourage it to tread consistently on the right path as well.Keywords :  Dhawq, eros, heart, exoteric, esoteric, al-Haqq, al-`Adl, al-Shidq Abstrak : Artikel ini membahas istilah-istilah epistemologi dan beberapa postulat dari seorang sufi terkenal abad ke-9, Abu `Abdu’lLahMuh ammad b.`Ali al-Hakim al-Tirmidzi, dalam upaya menggambarkan perjalanan suluk seorang sufi menuju Realitas Mutlak. Dalam gaya pemikirannya tentang sufi, kita menemukan bahwa figur ini cenderung  menekankan hubungan-hubungan yang kuat antara wal āyah (kewalian sufi dan ma‘rifa (pengetahuan sufi di satu sisi, dan antara keduanya dengan filsafat moral sufi.  Jadi, tidak aneh jika kita menemukan kecenderungan - kecenderungan etis yang dominan dalam setiap aspek  pemikiran epistemologinya. Dan epistemologi sufi dalam perspektif para filsuf lebih menekankan potensi inner Diri yang positif daripada menghapuskan “cara-cara syaitan” dalam hati, karena - menurut pendapat al-Tirmidzi – ia akan meningkatkan

  1. Alumina-tantalum composite for femoral head applications in total hip arthroplasty

    International Nuclear Information System (INIS)

    Dense composite laminates of alumina (Al2O3) and tantalum (Ta) were fabricated by hot pressing and tested in vitro for potential use as a femoral head material in total hip arthroplasty (THA). Al2O3-Ta composite laminates hot pressed at 1450 deg. C and 1650 deg. C had flexural strengths of 940 ± 180 MPa and 1090 ± 340 MPa, respectively, which were far larger than the values of 420 ± 140 MPa and 400 ± 130 MPa for Al2O3 hot pressed at 1450 deg. C and 1650 deg. C, respectively. The interfacial shear strength, determined by a double-notched specimen test, was 310 ± 80 MPa for the composite laminate hot pressed at 1650 deg. C, indicating strong interfacial bonding between Al2O3 and Ta. Scanning electron microscopy (SEM), energy dispersive X-ray (EDS) analysis, and X-ray mapping of polished sections of the hot-pressed laminates showed the presence of an interfacial region formed presumably by diffusion of O (at 1450 deg. C) or O and Al (1650 deg. C) from Al2O3 into Ta. Composite femoral heads of Al2O3 and Ta could combine the low wear of an Al2O3 articulating surface with the safety of a ductile metal femoral head.

    For pollution research with regard to urban surface runoff, most sampling strategies to date have focused on differences in land usage. With single land-use sampling, total surface runoff pollution effect cannot be evaluated unless every land usage spot is monitored. Through a new sampling strategy known as mixed stormwater sampling for a street community at discharge outlet adjacent to river, this study assessed the total urban surface runoff pollution effect caused by a variety of land uses and the pollutants washed off from the rain pipe system in the Futian River watershed in Shenzhen City of China. The water quality monitoring indices were COD (chemical oxygen demand), TSS (total suspend solid), TP (total phosphorus), TN (total nitrogen) and BOD (biochemical oxygen demand). The sums of total pollution loads discharged into the river for the four indices of COD, TSS, TN, and TP over all seven rainfall events were very different. The mathematical model for simulating total pollution loads was established from discharge outlet mixed stormwater sampling of total pollution loads on the basis of four parameters: rainfall intensity, total land area, impervious land area, and pervious land area. In order to treat surface runoff pollution, the values of MFF30 (mass first flush ratio) and FF30 (first 30% of runoff volume) can be considered as split-flow control criteria to obtain more effective and economical design of structural BMPs (best management practices) facilities.

    We investigate the generalized gravitational entropy from total derivative terms in the gravitational action. Following the method of Lewkowycz and Maldacena, we find that the generalized gravitational entropy from total derivatives vanishes. We compare our results with the work of Astaneh, Patrushev, and Solodukhin. We find that if total derivatives produced nonzero entropy, the holographic and the field-theoretic universal terms of entanglement entropy would not match. Furthermore, the second law of thermodynamics could be violated if the entropy of total derivatives did not vanish.

  10. Microstructure evolution and oxidation behaviour of Tif/TiAl3 composites

    International Nuclear Information System (INIS)

    In this paper, Tif/TiAl3 composites were fabricated by infiltration-in situ reaction method and its oxidation behaviours were investigated by cyclic oxidation testing at 700 oC, 800 oC and 900 oC. The microstructure evolution and oxidation of Tif/TiAl3 composites were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray diffraction (EDX). The reaction between Ti3Al particles and Al was more violent than that of Ti fibres and Al. Ti3Al/Al reaction consumed a large amount of Al and inhibited the reaction of Ti fibres indirectly. Reactant of Ti fibres was TiAl3 at 700 oC, and four reaction layers surrounding Ti fibre (Ti3Al, TiAl, TiAl2 and TiAl3 from inner to outside) were observed above 800 oC. The thickness of the total reaction layers increased little with temperature and time, while the thickness of inner reaction layers increased remarkably. A model corresponding to the microstructure evolution process was drawn schematically. Oxidation resistance of Tif/TiAl3 composites decreased with increasing of temperature, and changed from cubic law at 700 oC to parabolic law at 900 oC. The oxidation weight gain of Tif/TiAl3 composite was dominated by the exposed Ti fibres. Due to outward diffusion of Ti and Al element, the oxide of Ti fibre at 900 oC changed to mushroom-shape. Fortunately, when TiAl3 was oxidized, a thin and continuous Al2O3 layer was formed, protecting matrix from further oxidation.

    The current instabilities of high electron mobility transistors (HEMTs), based on thin double AlN/GaN/AlN heterostructures (∼0.5 μm total thickness), directly grown on sapphire substrates, have been analyzed and compared for different AlN top barrier thicknesses. The structures were capped by 1 nm GaN and non-passivated 1 μm gate-length devices were processed. Pulsed I–V measurements resulted in a maximum cold pulsed saturation current of 1.4 A mm‑1 at a gate-source voltage of +3 V for 3.7 nm AlN thickness. The measured gate and drain lag for 500 ns pulse-width varied between 6%–12% and 10%–18%, respectively. Furthermore, a small increase in the threshold voltage was observed for all the devices, possibly due to the trapping of electrons under the gate contact. The off-state breakdown voltage of V br = 70 V, for gate-drain spacing of 2 μm, was approximately double the value measured for a single AlN/GaN HEMT structure grown on a thick GaN buffer layer. The results suggest that the double AlN/GaN/AlN heterostructures may offer intrinsic advantages for the breakdown and current stability characteristics of high current HEMTs.
