    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: 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 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.

    acciones que financiaron la adquisición de medicamentos fueron obtenidas en el sistema Siga Brasil y clasificadas según los programas de asistencia farmacéutica. Los valores liquidados fueron identificados para cada programa. Para 2006 y 2007, fueron pesquisadas las adquisiciones de anti-retrovirales. Con relación a los medicamentos del Programa de Dispensación en Carácter Excepcional, se confrontaron los datos de la acción presupuestaria con aquellos disponibles en el Sistema Único de Salud. Los valores obtenidos fueron deflacionados aplicándose el Índice de Precios al Consumidor Amplio. Fue efectuado el análisis exploratorio de los datos. RESULTADOS: El gasto en 2007 fue 3,2 veces el de 2002 y la participación del gasto con medicamentos en el gasto total aumentó de 5,4% en 2002 a 10,7% en 2007. El gasto con los medicamentos de la atención básica tuvo aumento de 75% y con medicamentos de los programas estratégicos, de 124%. En caso de los anti-retrovirales el aumento fue de aproximadamente 6%, pero con aumento de 77% de 2005 a 2006, seguida de reducción de 29% de 2006 a 2007. El aumento más expresivo del gasto fue observado con los medicamentos de dispensación en carácter excepcional, 252% de 2003 a 2007. CONCLUSIONES: Hubo aumento significativo del gasto con medicamentos entre 2002 y 2007, habiendo mayor participación en ese gasto de los anti-retrovirales y medicamentos de dispensación excepcional, los cuales son constituidos por número expresivo de fármacos protegidos por patentes.OBJECTIVE: To analyze the evolution of the Ministry of Health's spending on drugs.

    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.

    1984-12-01

    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.

    Full Text Available El debate sobre el efecto del dinero invertido en campaiias sobre los resultados de las elecciones ha puesto en tela de juicio cuestiones centrales sobre la calidad de la democracia y la efectividad de las e1ecciones como mecanismo de control ciudadano. EI gasto en campana es una variable central a la hora de evaluar su éxito, por lo tanto, la forma en que se mide influye en las conclusiones a las que se llega con respecto a su efecto en los resultados de una elección. En este artículo se utiliza el caso chileno (específicamente, las elecciones de 2005 y 2009 para analizar los dos métodos más com unes de medir el gasto en campana y proponer un tercero que estima de mejor forma sus efectos. Esta contribución metodológica complementa y refIna el conocimiento que ya se poseía sobre la forma en que d gasto afecta los resultados electorales, a la vez que abre una línea de investigación que permite evaluar otros aspectos de la dinámica que relaciona el gasto en campafias con el desempeno electoral. Sugerimos que el camino a seguir se centre en la fiscalización dei gasto efectivo y no en reducir los límites al gasto reportado.

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.

    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.

    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.

    Full Text Available OBJETIVO: Analisar a evolução de estimativas do gasto federal com o Programa de Saúde Mental desde a promulgação da lei nacional de saúde mental. MÉTODOS: O gasto federal total do Programa de Saúde Mental e seus componentes de gastos hospitalares e extra-hospitalares foi estimado a partir de 21 categorias de gastos de 2001 a 2009. Os valores dos gastos foram atualizados para valores em reais de 2009 por meio da aplicação do Índice de Preços ao Consumidor Amplo. 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 El objetivo de este trabajo fue determinar costos de producción y rentabilidad de caprinos en un sistema de producción extensivo. La investigación se realizó durante los meses de enero-junio de 2011 en las localidades: Monte de Dios y San Lucas del Maíz, municipio de Tejupilco, Estado de México; la información provino de una encuesta aplicada a 37 productores. Los costos de producción consideraron solamente conceptos monetarios desembolsados efectivamente por productores; existieron rubros que no se incluyeron, ya que estos los incluyó la economía familiar o cuyos costos de oportunidad fueron iguales a cero; u otros que se omitieron, debido a que no se utilizaron. El costo de producción por cabeza estimado fue US$ 8,7, de éste, el costo variable y fi jo fue US$ 3,8 y US$ 4,9. El componente principal del costo variable fue el concepto de desparasitantes y el fi jo el mantenimiento de corrales. El ingreso medio por ventas consideró un peso de 35 kg y un precio por kilogramo de dos dólares; con lo que el ingreso total por animal fue US$ 71,2. Con ello, la ganancia neta se ubicó en US$ 62,5; en tanto que la relación benefi cio-costo fue 8:1. El costo de producción decaprinos, bajo este sistema de producción, fue menor que latercera parte del ingreso por venta, debido a la poca magnitud de gastos de producción; por lo que la ganancia por unidad vendida fue siete veces superior al costo de producción.

    Full Text Available INTRODUÇÃO: A atividade física apresenta efeito protetor contra doenças crônicas e fatores de risco cardiovascular; no entanto, o gasto calórico necessário para promover a prevenção do diabetes permanece especulativo. OBJETIVO: Analisar o gasto calórico dos diferentes domínios da atividade física (trabalho, deslocamento, atividade doméstica, tempo livre e atividade física total como preditores da ausência de diabetes em adultos de ambos os sexos. MÉTODOS: Estudo transversal realizado na cidade de Lauro de Freitas, Bahia, Brasil (2007-2008 com amostra constituída por 522 indivíduos maiores de 18 anos, sendo 302 do sexo feminino e 220 do sexo masculino. Foram construídas curvas Receiver Operating Characteristic (ROC e comparadas as áreas sob as mesmas, além de verificar-se a sensibilidade e especificidade para identificar os melhores pontos de corte entre os diferentes domínios da atividade física e a ausência de diabetes. Foi utilizado o intervalo de confiança a 95%. RESULTADOS: Entre os diferentes domínios de atividade física analisados encontrou-se significância estatística nas áreas sob a curva ROC para o tempo livre, deslocamento e para atividade física total. Observou-se também que o gasto calórico na atividade física total de 830kcal/semana quando analisados apenas os homens, e 1,774kcal/semana quando analisados homens e mulheres conjuntamente, foram os melhores pontos de corte para predizer a ausência de diabetes. CONCLUSÃO: A prática da atividade física deve ser sugerida em níveis adequados para indivíduos de ambos os sexos visando contribuir para a prevenção do diabetes.

Sin embargo, el gasto militar no se está reduciendo en la misma proporción en todos los países europeos (incluso sigue aumentando fuera de Europa y persisten algunos llamamientos a incrementarlo y a considerarlo uno de los motores para salir de la crisis. Esta paradójica situación se explica a partir de determinadas concepciones de la seguridad y de la economía de la industria militar. Tras analizar la situación actual en los casos de España y Grecia, y criticar esas concepciones, propongo una estrategia diferente respecto a las políticas de seguridad europeas.

    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.

MATERIAL Y MÉTODOS: A partir de 1997, y durante tres bienios consecutivos, se ha desarrollado el análisis contable, sistematizado y exhaustivo de los flujos de financiamiento y gasto orientados al suministro de bienes y servicios relacionados con la atención y la prevención del VIH/SIDA, ejercicio denominado Cuentas Nacionales de SIDA. RESULTADOS: Se observa un incremento real y sostenido en el gasto total destinado al combate de la epidemia, estimado en 143% y ejercido en diferentes rubros, pero particularmente en el gasto en medicamentos antirretrovirales. No obstante, comparado con otros países de la región, el gasto mexicano en VIH/SIDA tiene un menor sesgo en cuanto a la asignación entre prevención y tratamiento. DISCUSIÓN: El gobierno mexicano se ha comprometido a garantizar el acceso universal al tratamiento antirretroviral para los pacientes con VIH/SIDA que lo necesiten y, al mismo tiempo, a mantener e incluso aumentar los esfuerzos en prevención. Estas actividades demandan incrementos en los recursos destinados para combatir la epidemia, por lo que es importante dar seguimiento a la eficiencia con que se estén utilizando los mismos, de forma que se pueda mejorar su asignación y focalización.OBJECITVE: This paper first presents the trend of HIV/AIDS expenditures in Mexico between 1997 and 2002.

    Full Text Available La falta de protección financiera en salud es una enfermedad recientemente diagnosticada de los sistemas de salud. 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. The most obvious symptom is that families face economic ruin and poverty as a consequence of financing their health care.

    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.

    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.

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.

    Total reaction cross sections σR for some proton-rich isotones (N = 10) near 23Al on a carbon target have been measured at intermediate energies in the experiment performed at the Radioactive Ion Beam Line of the Heavy Ion Research Facility in Lanzhou. The Z-dependence of σR shows a remarkable enhancement for 23Al relative to its neighbours. The difference factor d has been deduced from the measured σR by using the Glauber or Boltzmann-Uehling-Uhlenbeck models. From the above analysis, a possible one-proton halo structure is suggested for 23 Al.

  8. La regulación estatal de la actividad económica a través del gasto público

    1989-12-01

    Full Text Available Con frecuencia los estudios sobre finanzas públicas dan por sentada la existencia del Estado, sin hacer explícita la concepción acerca de su naturaleza, sus funciones y sus límites. Para adelantar el examen del gasto público los tratadistas se contentan las más de las veces con una descripción de las funciones del Estado, relegando su explicación. El aparato de Estado es la forma de organización para adelantar las funciones derivadas de su naturaleza. Las administraciones públicas y las empresas públicas contituyen las formas concretas de organización estatal. Lo anterior pone de presente la necesidad de avanzar en la construcción
    de la teoría del Estado, para así poder comprender la organización estatal; su razón de ser y su quehacer, así como los factores que determinan y limitan sus finanzas. El camino inverso, que es el que se ha seguido, estrecha y tergiversa la problemática de las finanzas públicas y las reduce al frío análisis de los ingresos y gastos públicos: Estado y economía se relacionan en forma inmediata, principalmente por la vía del gasto público, sin examinar éste como la materialización parcial de las funciones del Estado. El gasto público se debe examinar, en nuestro entender, no como la forma de intervención del Estado en la economía, sino como un medio de regulación.

    Full Text Available El artículo desarrolla un análisis desagregado del impacto redistributivo y recaudatorio del impuesto al valor agregado (IVA actual en México, identificando la capacidad de redistribución del tratamiento impositivo dentro de cada categoría familiar de gasto. Se utilizan técnicas de microsimulación para el análisis del impacto redistributivo diferencial de cada concepto de gasto, empleando el método de descomposición total de contribución aislada a la capacidad redistributiva global del impuesto. Para la aplicación empírica, empleamos los microdatos de la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH 2002. El estudio pone de manifiesto la capacidad de compensación entre los distintos grupos de contribuyentes, al identificar las directrices de ejecución de determinadas reformas fiscales sobre el IVA. Los resultados indican que un IVA diferenciado de 4, 7 y 15% incrementa la recaudación en 32.8% respecto de su nivel actual, y contribuye positivamente con los dos objetivos de justicia social tributaria: Mejorar la equidad horizontal y la vertical.

    A set of density-functional calculations for clean and O-covered Al(111) are presented. At low O coverages the potential energy surface (PES) of chemisorbed O is investigated. The PES indicates large barriers (0.8 eV) against O diffusion and a large corrugation of the equilibrium O height over...... the Al(111) while only a moderate energy gain (5 eV per atom) is found upon Oz dissociation over the surface. The possible existence of ''hot'' O adatoms after O-2 dissociation is discussed on the basis of the presented PES and existing dynamical simulations on model potentials. At high O coverages...... an attractive O-O interaction is identified together with an enhancement in the dipole moment induced per O atom. Finally, Tersoff-Hamann-type scanning tunneling microscopy (STM) topographs are derived based on the calculated one-electron wave functions and spectra. For the clean Al(111) a theoretical STM...

    Full Text Available Co6Al2HT hydrotalcite-like compounds were synthesized by three different methods: co-precipitation, microwaves-assisted and ultrasound-assisted methods. The mixed oxides obtained after calcination were studied by several techniques: XRD, TEM, H2-TPR and XPS. They were also tested as catalysts in the reaction of total oxidation of toluene. The physico-chemical studies revealed a modification of the structural characteristics (surface area, morphology as well as of the reducibility of the formed mixed oxides. The solid prepared by microwaves-assisted synthesis was the most active. Furthermore, a relationship between the ratio of Co2+ on the surface, the reducibility of the Co-Al mixed oxide and the T50 in toluene oxidation was demonstrated. This suggests a Mars Van Krevelen mechanism for toluene total oxidation on these catalysts.

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.

    The structure of germanene on an Al(111) surface has been experimentally investigated using the total-reflection high-energy positron diffraction (TRHEPD) method. The observed spot intensities are asymmetric, revealing no mirror symmetry in the atomic coordinates of germenene with respect to the direction. Quantitative TRHEPD rocking curve analysis, based on dynamical diffraction theory, has revealed that the germanene layer has a 3 × 3 structure with asymmetrical buckling due to the protrusion of one of the Ge atoms in the unit cell, which is unlike the structural model proposed in previous studies. The magnitude of the buckling was found to be 0.94 Å, and the spacing between the germanene and the Al(111) substrate to be 2.51 Å. The new structure proposed in the present investigations, though different from that reported in studies before, does not contradict the other characteristics which were found experimentally in the previous studies.

    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).

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. En el marco de la promulgación del Decreto Supremo 068-2006-PCM, en octubre de 2006, por el cual se establece la culminación de las transferencias

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

En razón de la brevedad, se detallan sucintamente los puntos fundamentales del mensaje y se dejan en el apartado de Discusión algunos temas polémicos que requieren premisas ideológicas, discutibles por definición. 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

También se efectuaron predicciones para el periodo de septiembre de 2013 a diciembre de 2014 para observar el impacto de la medida en un horizonte superior al real Resultados: el análisis contrafáctico estimó el descenso en el número de recetas en un 12,18% y el del gasto farmaceutico en un 12,83%, mientras que al calcularse mediante el análisis de intervención fueron 12,75% y 14,03%, respectivamente. Conclusiones: la reducción estimada del número de recetas para el periodo de junio de 2012 hasta agosto de 2013 es similar a la ofrecida por el MSSSI, mientras que para la serie del gasto farmacéutico fue inferior a la ofrecida por el MSSSI. La metodología de Box-Jenkins genera errores de predicción menores al 3% por lo que se considera útil para anticipar fiablemente los consumos futuros.

Utilizando análisis de incidencia y microdatos, se generaron distribuciones de las transferencias del gasto público en salud por familia. El análisis se completa con el cálculo de índices de desigualdad, los resultados arrojan una paulatina mejoría en la progresividad del gasto en salud en el tiempo de estudio, con mayor progresividad de los servicios de salud prestados por la Secretaría de Salud y menores avances en los servicios del ISSSTE y Pemex. 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.

La administración de nutrición parenteral total (NPT aumenta el riesgo de aparición de BAC. El objetivo de nuestro estudio fue determinar la tasa de incidencia y los factores de riesgo de BAC en pacientes con NPT hospitalizados en plantas médico-quirúrgicas. Métodos: Estudio observacional, analítico, retrospectivo donde se analizaron a todos los pacientes adultos no críticos que precisaron NPT desde enero de 2010 hasta noviembre de 2011. El punto final clínico fue la BAC. La tasa de incidencia de BAC se calculó en forma de episodios por cada 1.000 pacientes-día de cateterización. Los factores predictivos independientes de BAC se determinaron mediante regresión logística. Resultados: Durante el periodo de estudio precisaron NPT un total de 331 pacientes. La duración media del CVC fue de 12,4 (DE 8,7 días y la NPT fue infundida durante un periodo medio de 10,4 (DE 8,3 días. 47 pacientes presentaron BAC, con una tasa de incidencia de 11,4/1.000 pacientes-día de CVC y de 13,7/1.000 pacientes-día de NPT.

El objetivo de la investigación fue predecir la aparición del síndrome de preeclampsia-eclampsia mediante la identificación de alteraciones del gasto cardíaco. Método: Se realizó un estudio observacional, descriptivo, longitudinal y analítico, de cohorte prospectiva, donde se determinó, por ecocardiografía, el gasto cardíaco en 31 embarazadas, entre las semanas 11 y 13,6 de gestación como único valor; y mediante seguimiento prenatal, se observó la aparición o no del síndrome de Preeclampsia-Eclampsia. Resultados: Se logró el seguimiento de 31 embarazadas a las que se le midió el gasto cardíaco, y se encontró una prevalecía de la enfermedad de 12,9 % con un 64,5 % de pacientes correctamente diagnosticados, con una sensibilidad de 75 %, con valor predictivo positivo de 23 %, especificidad de 62 % y valor predictivo negativo de 94%, con un riesgo relativo de 4,1 (intervalo de confianza 95 %, 0,48-35,6. Conclusiones: Es posible establecer la medición de gasto cardíaco como estudio de escrutinio para predecir la aparición del síndrome de Preeclampsia desde el control prenatal, y contribuir así a la disminución de la muerte materna. / Abstract Introduction and Objectives: Hypertension is the most common medical complication of pregnancy, and it can leave permanent sequelae such as neurological, hepatic, hematological or renal disorders.

    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. La TMB es la mínima cantidad de energía que un organismo requiere para estar vivo y representa del 60-70% del total del gasto energético (TGE, en la mayoría de los adultos sedentarios. La AF representa entre el 25-75% del TGE y la TID representa cerca del 10% del TGE. Debido a su simplicidad, bajo costo y alta precisión el método comúnmente usado en el estudio de la composición corporal es la antropometría.

    Full Text Available Energy expenditure was measured by indirect calorimetry in 17 adult patients (8 women and 9 men before surgery, 4 hours immediately after surgery , and 24 hours late after surgery in patients undergoing elective surgery of small-to-medium scope. MATERIAL AND METHODS: The total duration of surgery ranged from 2 to 3 hours. Repeated measures were performed on the same patient, so that each patient was considered to be his/her own control. All patients received a 5% dextrose solution (2000 mL/day throughout the postoperative period. RESULTS: Men showed a reduction in CO2 production during the immediately after surgery period (257±42 mL/min compared to before surgery (306±48 mL/min and late after surgery (301±45 mL/min; this reduction was not observed in women. Energy expenditure was also lower in men during immediately after surgery (6.6 kJ/min. None of the other measurements, including substrate oxidation, showed significant differences. CONCLUSION: Therefore, elective surgery itself cannot be considered an important trauma that would result in increased energy expenditure. According to this study, it is not necessary to prescribe an energy supply exceeding basal expenditure during the immediate after-surgery period. The present results suggest that the energy supply prescribed during the postoperative period after elective surgery of small-to-medium scope should not exceed 5-7 kJ/min, so the patient does not receive a carbohydrate overload from energy supplementation.A resposta metabólica ao trauma cirúrgico ocorre imediatamente após a cirurgia e recomenda-se que a oferta calórica, nesta situação, seja igual ao metabolismo basal acrescido de 20-30%, considerado fator de injúria. No entanto, níveis elevados de glicemia e aumento na produção de CO2 são freqüentemente observados nestas ocasiões . OBJETIVO: O principal objetivo do presente estudo foi medir o gasto energético basal, o gasto energético imediatamente e 24 horas ap

    Full Text Available La hipótesis de que los gastos en consumo puedan ser asimétricos es del máximo interés desde el punto de vista de la política económica. Si determinados elementos del consumo agregado reaccionan de forma diferente en las fases de alza y caída del ciclo económico, dicha información habrá de ser tenida en cuenta a la hora de diseñar medidas activas de estímulo a la demanda. En este trabajo tratamos de contrastar si los gastos de consumo españoles presentan esta característica. Empleamos para ello dos versiones de un estadístico de contraste basado en el concepto de deformación temporal que resulta especialmente apropiado para este objetivo. Adicionalmente y dado que las asimetrías en dichos gastos han sido relacionadas con la durabilidad, como segundo objetivo de este trabajo trataremos de ver si realmente existe una relación entre bienes de consumo duradero y conducta asimétrica. La evidencia empírica hallada muestra que existen asimetrías en diferentes categorías de gasto, si bien no es ésta una característica específica de la durabilidad.

Material y métodos. Se realizó un análisis descriptivo del acceso y gasto en medicamentos, y se identificaron factores relacionados con la prescripción mediante una regresión logística en 3 324 usuarios. Resultados. El 78% de usuarios recibieron prescripción de medicamentos. El 92% de los usuarios de la seguridad social y 35% de la Secretaría de Salud obtuvieron los medicamentos sin pago directo (p =0.000. La región con mayor índice de pobreza presentó menor acceso gratuito a los medicamentos. Entre los usuarios que gastaron en medicamentos, la mediana del gasto fue de 40.00 pesos (12.50 dólares, lo que resultó mayor en instituciones privadas que en públicas. Conclusiones. El acceso y el gasto en medicamentos se encuentran relacionados con las características socioeconómicas de los grupos de población y con las instituciones donde estos últimos se atendieron. Lograr mayor equidad en el acceso a medicamentos representa uno de los retos del sistema de salud en México.

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.

    Full Text Available As projeções de gastos com saúde apontam para um crescimento considerável das despesas em decorrência do envelhecimento populacional. No entanto, estudos mostram que os gastos se concentram no fim da vida e, dessa forma, projeções que não levam em conta variáveis de proximidade à morte tendem a superestimar as projeções. O objetivo deste trabalho é analisar a magnitude dos gastos com internações públicas no Brasil por status de sobrevivência, e identificar se existe uma relação entre despesas com internações para indivíduos próximos à morte e idade à morte. O banco de dados empregado é oriundo do Sistema de Informações Hospitalares do DATASUS - SIH/DATASUS - para o período de 1995 a 2007 no Brasil. Foi analisada a evolução dos gastos totais e a tendência dos gastos por grupo etário para aqueles pacientes que tiveram como motivo de saída do hospital a alta (sobreviventes ou o óbito (pacientes terminais. A fim de analisar o efeito do status de sobrevivência sobre os gastos com internações no futuro, simulamos projeções de gastos em 2050, desagregados entre gastos de sobreviventes e gastos relacionados à morte. Os resultados mostram que o padrão de gastos por status de sobrevivência no Brasil é crescente por grupo etário para o grupo de sobreviventes, e decrescente para os indivíduos que faleceram. Também se verificou que a razão de gastos mortos/sobreviventes diminui com a idade. A simulação da projeção de gastos com internações para 2050 mostra que quando se considera apenas o perfil etário dos gastos médios em 2007, há um crescimento de mais de 380% nos gastos com internações em 2050 quando comparado a 2007, mas quando os gastos são projetados segundo o status de sobrevivência, o crescimento não passa de 70%. Projeção retrospectiva para 2007 mostra que o efeito do envelhecimento é menor quando o efeito da proximidade à morte é levado em consideração. Os resultados parecem

    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. Co{sub 3}O{sub 4}, Co{sub 2}AlO{sub 4} or CoAl{sub 2}O{sub 4}), 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 CO{sub 2} and H{sub 2}O 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)

Para se alcançar tal objetivo é adotado um método não- experimental conhecido como pareamento baseado no escore de propensão (propensity score matching, utilizando os microdados da Pesquisa de Orçamentos Familiares (POF 2002-2003. Realiza-se, ainda, uma análise de sensibilidade dos resultados obtidos a fim de se verificar a robustez do método à presença de variáveis não observadas, bem como à especificação do modelo de escore de propensão. Os resultados estimados sugerem um efeito positivo das transferências monetárias sobre o consumo das famílias pobres beneficiárias. O fato de os recursos serem prioritariamente destinados a despesas com alimentos, educação, produtos de higiene e vestuário em detrimento de itens como bebidas e cigarros, despesas diversas e bens duráveis significa que, em alguma medida, estes recursos estão sendo gastos de forma eficiente. É provável, também, que o aumento do consumo destas famílias eleve o seu nível de bem-estar, representando um "alívio" imediato sobre a pobreza.The aim of this work is to analyze the effects of cash transfers of public programs on household’s expenditures and their components, taking the Brazilian program Bolsa-Escola as a representative example.

    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.

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 empirical analysis is based on cointegration and vector error correction models and the data ranges from the 1st quarter/1999 to the 3rd quarter/ 2008. The results show that the Brazilian government follows a "spend and tax" policy. It means that more government spending leads to permanently higher taxes.

    Full Text Available A 90 mujeres con sobrepeso y obesidad del área de atracción del Programa de Atención Integral en Salud (PAIS se les midió la tasa metabólica basal por calorimetría indirecta y se les evaluó tanto el nivel de actividad física como la ingesta de energía y macronutrientes. Se observó una correlación positiva entre el Índice de Masas Corporal y la tasa metabólica basal de estas mujeres. Aunque se encontró diferencia significativa entre el gasto metabólico basal estimado por la ecuación de Harris-Benedict y el gasto metabólico basal medido por calorimetría indirecta, no se encontró diferencia significativa en el total de energía expedida obtenida por ambos métodos. En estas pacientes con sobrepeso no se encontró diferencia significativa entre el gasto energético total y la ingesta energética diaria obtenida, lo que sugiere un estado de equilibrio energético adaptado a la nueva condición de fisiológica. Según la distribución de macronutrientes fue la grasa la que excedió la recomendación dietética diaria.A group of 90 women with overweight and obesity, residing in the area covered by the Program for Integral Attention in Health (PAIS participated in this study. The following measurements were made: basal metabolic rate by indirect calorimetry, level of physical activity and intake of energy and macronutrients. There was a positive correlation between Body Mass Index and the basal metabolic rate for these women. Although a significant difference was found between the average basal metabolic expenditure of the group, as estimated by the Harris-Benedict equation and average basal metabolic expenditure as measured by indirect calorimetry, there was no significant difference between total energy expenditure as estimated by both methods. No significant difference was found between average energy expenditure and average energy intake for these women, suggesting a state of energy balance which is an adaption to the new

    Full Text Available O objetivo deste texto é investigar os principais determinantes dos gastos em P&D no Brasil. Utilizamos neste trabalho a base de dados da ANPEI sobre indicadores de capacitação e inovação tecnológica no Brasil, abrangendo o período de 1994 a 1998. Conciliamos esta base de dados com várias técnicas econométricas, visando garantir robustez aos resultados. Os resultados encontrados mostram que os gastos em P&D se comportam como um random walk, e que firmas maiores gastam menos em P&D como proporção do seu faturamento bruto. Nas equações para os determinantes de P&D, o investimento em capital físico é a variável mais importante, indicando uma forma de complementaridade entre os dois tipos de investimento. Finalmente, a margem de lucro líquida parece não ter influência nos gastos em P&D, que parece ser um investimento de mais longo prazo.This paper aims at examining the determinants of R&D expenditures in Brazil. We use a new database (from ANPEI with firm level information on R&D and other technological expenditures from 1994 to 1998, and several econometric techniques. The results show that R&D expenditures follow a random walk and that larger firms spend proportionally less in R&D. The main determinant of R&D seems to be investments in physical capital, which indicates some form of complementarity between the two types of investment. Finally, profitability does not seem to be an important determinant of R&D expenditures in Brazil, suggesting that long-term determinants are more important.

Los resultados obtenidos indican que, en general, aumentos en el gasto público municipal repercuten de forma positiva sobre las posibilidades de reelección de los gobiernos locales y, fundamentalmente, cuando este aumento se realiza en el período preelectoral. Asimismo, se aprecia que existen otras variables que afectan de forma positiva sobre las probabilidades de reelección, como son el volumen de ingresos por transferencias, que sean partidos de derechas, o el hecho de que un municipio haya obtenido mayoría absoluta en las elecciones previas. Por el contrario, el número de años que un alcalde lleva en el cargo presenta un impacto negativo sobre las probabilidades de reelección.

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.

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.

Un primer índice simple de 4 variables, llamado EPI y otro índice más robusto, llamado MRE, compuesto por el promedio simple de tres sub índices, uno monetario, otro real-fiscal y otro que mide la evolución del sector externo. Se trabaja bajo el supuesto de que el gasto público social consolidado como porcentaje del PBI tiene un efecto positivo en reducir la pobreza, mientras que la inestabilidad macroeconómica, medida como un empeoramiento de los índices tiene un efecto negativo y se busca discernir cual de los efectos domina. Se llega a la conclusión de que el efecto negativo de la inestabilidad macroeconómica domina al efecto positivo del gasto público social consolidado en un 76% de los casos cuando se utiliza el EPI y un 65% cuando se utiliza el MRE. A su vez, las probabilidades de éxito de los índices, entendiendo el éxito como la probabilidad de que la tasa de pobreza se mueva en dirección opuesta a los índices, resultó de 74% para el EPI y de 68% para el MRE.Clasificación JEL: E21, E66, N10, I32, I38.AbstractThis paper studies the evolution of the poverty rate in relation to two macroeconomic performance indexes. A first simple index of four variables, called EPI, and another more complex called MRE, composed by the simple average of three sub-indexes, a monetary, a real-fiscal and one that measures the evolution of the external sector. It works under the assumption that the public social expenditure consolidated as a percentage from the GDP has a positive effect on reducing poverty, while macroeconomic instability, measured as a deterioration of the indexes has a negative effect, and the aim is to determine which one of the two dominates.

Objetivo: conocer la concordancia del gasto de energía en reposo medido por calorimetría indirecta con el estimado con diferentes ecuaciones de predicción en un grupo de escolares de la Ciudad de México. Material y método: se realizó un estudio transversal en escolares de 6 a 12 años de edad (n = 63. El gasto de energía en reposo fue medido mediante calorimetría indirecta, se usó como referencia para conocer la exactitud de las ecuaciones de predicción de Schofield, de FAO/OMS, de Tverskaya y de Harris-Benedict. Para conocer la concordancia entre las ecuaciones y el gasto de energía en reposo se estimaron coeficientes de correlación intraclase (r. Resultados: en esta población las cuatro ecuaciones sobrestimaron el gasto de energía en reposo; en promedio, las diferencias fueron de 12.1 a 97.5 kcal/día. Las ecuaciones que tuvieron la mayor concordancia con el gasto de energía en reposo medido fueron las de Schofield y las de FAO/OMS (r = 0.74, mientras que las de Tverskaya y de Harris-Benedict tuvieron la menor (r = 0.64. La concordancia fue menor en los niños más pequeños, especialmente con las ecuaciones de Harris-Benedict (r = 0.33 y Tverskaya (r = 0.47. Conclusiones: aunque se requiere más investigación sobre la conveniencia de usar ecuaciones de predicción del gasto de energía en reposo en población pediátrica de México, nuestros resultados muestran que las ecuaciones de FAO/OMS o las de Schofield son las más adecuadas.

Si bien es cierto que ya nos hemos acostumbrado al, a veces, complejo entramado del efecto impositivo, no es menos cierto que en los últimos tiempos la tan recurrente crisis económica y, naturalmente, el irresponsable despilfarro previo a la misma han supuesto la introducción de determinadas normas tributarias encaminadas a intentar una mayor recaudación de impuestos...

    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.

    Full Text Available Objetivo. Analizar algunos de los determinantes del consumo de tabaco en los hogares en México. Material y métodos. Los datos provienen de la Encuesta Nacional de Ingresos y Gastos de los Hogares (1984-2000. El análisis se realizó en dos periodos: 1984-1992 y 1994-2000. Las posibilidades de consumo de tabaco en hogares (PCTH fueron estimadas mediante un modelo de regresión logística. Resultados. La PCTH durante el primer periodo fue superior a dos veces a partir del decil 6 (RM=2.03, IC 95%, 2.03-2.04 y durante el segundo periodo a partir del decil 8 (RM=2.06, IC 95%, 2.05-2.07. Los hogares del decil 1 gastaron en promedio de 9 a 22% de sus ingresos en tabaco; casi todos los hogares del decil 10, solamente 1%. Conclusiones. Los hogares con mayores ingresos consumieron más tabaco que los hogares de menores ingresos, sin embargo, los hogares de más bajos ingresos destinaron un porcentaje más importante de éstos al consumo de tabaco.Objective. To analyze selected determinants of tobacco consumption in Mexican homes. Material and Methods. Data from the National Household Income and Expenditure Survey, 1984-2000, were analyzed. The analysis was conducted for the years 1984-1992 and 1994-2000. The likelihood of tobacco consumption in households was estimated with a logistic regression model. Results. Tobacco consumption during the first period was two times more likely from decile six (OR=2.03, 95%, CI: 2.03-2.04 and during the second period from decile eight (OR=2.06, 95%, CI: 2.05-2.07. Households from decile one spent on average 9-22% of their income on tobacco; almost all of the households from decile ten spent only 1% of their income on tobacco. Conclusions. Households with higher income consumed more tobacco than households with low income; nevertheless, households with the lowest income devoted a greater proportion of income to tobacco consumption.

OBJETIVO: Comparar os efeitos agudos do método circuito (MC com o método tradicional (MT sobre o GE. MÉTODOS: Trata-se de uma pesquisa com delineamento crossover e aleatorizado, a amostra foi composta por 10 homens adultos treinados com idade entre 18 e 29 anos. Foram realizadas duas sessões experimentais com wash out de sete dias: no MC os exercícios foram realizados alternados por segmento em forma de estações, durante o MT os exercícios foram realizados em séries consecutivas. Ambos os métodos seguiram a mesma sequência de oito exercícios com o mesmo trabalho total: 60% de 1RM, 24 séries/estações e 10 repetições. O lactato sanguíneo foi coletado em repouso e a cada três séries/estações. O ar expirado foi coletado por 30 minutos antes e ~31 minutos durante todas as sessões de treinamento. O GE aeróbio de exercício (GEAE, kj e do intervalo de recuperação (GEAIR, kj foram estimados pela calorimetria indireta através da medida do consumo de oxigênio e o GE anaeróbio (GEA, kj pela concentração de lactato sanguíneo ([La]. O GE total (GET, kj foi registrado pelo somatório do GEA, GEAE e GEAIR. RESULTADOS: Os dados demonstraram que o GEA foi maior no MT do que o MC, no entanto, o GEAE, GEAIR e o GET não foram diferentes significativamente entre os métodos. O MT apresentou maior [La] do que o MC. CONCLUSÃO: Conclui-se que o MC e o MT produzem similar GET, contudo, percebe-se que o MT utiliza mais a via anaeróbia do que o MC.

    Full Text Available CONTEXTO: Trata-se de um estudo sobre os gastos da família com o idoso com síndrome demencial. 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. Portanto, trata-se de um estudo de caso. RESULTADOS: Os achados sugerem que a repercussão é realmente grande e chega a comprometer, em média, 66% da renda familiar com gastos que podem chegar a 75% no caso de pacientes em estágio inicial, a 62% no estágio avançado e a cerca de 80% da renda familiar, quando associada a outra doença crônica. CONCLUSÕES: Da perspectiva da saúde pública, esses achados reiteram as conclusões das pesquisas prévias que apontam ser o aumento dos gastos com o cuidado uma das dimensões que contribuem para as alterações na saúde física e mental dos cuidadores. Ou seja, o impacto dos gastos pode ser considerado um indicador do grau de estresse e sobrecarga, principalmente emocional, que tão freqüentemente acompanha as responsabilidades dos cuidadores.BACKGROUND: This is a study on the expenses borne by families that care for an elderly individual with dementia.

    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.

  3. Gasto energético de repouso em pacientes com doença renal crônica Resting energy expenditure in patients with chronic kidney disease

    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.

    Full Text Available OBJETIVO: Descrever aspectos técnicos do Programa de Medicamentos de Dispensação em Caráter Excepcional do Ministério de Saúde do Brasil, especialmente em relação aos gastos com os medicamentos distribuídos. MÉTODOS: Os aspectos técnicos foram obtidos por meio de consulta a todas as portarias que regulamentaram o Programa. Gastos no período de 2000 a 2007 foram obtidos do Sistema de Informações Ambulatoriais do Sistema Único de Saúde. Foram analisados os medicamentos dispensados de 1993 a 2009, quantidades e valor de cada procedimento informados nas autorizações de procedimentos de alta complexidade para cada estado. RESULTADOS: O Programa mudou, com aumento do número de fármacos e apresentações farmacêuticas distribuídas e de doenças contempladas. Eram distribuídos 15 fármacos em 31 diferentes apresentações farmacêuticas em 1993, passando para 109 fármacos em 243 apresentações em 2009. Os gastos totais do Ministério da Saúde com medicamentos somaram, em 2007, R$ 1.410.181.600,74, quase o dobro do valor gasto em 2000: R$ 684.975.404,43. Algumas das doenças que representaram maiores gastos nesse período foram: insuficiência renal crônica, transplante e hepatite C. CONCLUSÕES: O Programa de Medicamentos de Dispensação em Caráter Excepcional está em constante transformação, visando aprimorar os instrumentos e estratégias que assegurem e ampliem o acesso da população aos medicamentos. Devem-se buscar alternativas para reduzir o impacto financeiro do Programa para que não haja prejuízos às outras áreas do sistema de saúde, dado o custo elevado das novas tecnologias.

    Ozturk, Emine

    2015-11-01

    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.

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.

    2016-02-01

    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.

  16. Incumbents without a Campaign Finance Advantage: Competition and Money in Chile’s Congressional Elections Sin una ventaja financiera: Incumbentes y el gasto electoral en las elecciones parlamentarias de Chile

    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 Os procedimentos em hemoterapia são complexos e caros. Exigem processos controlados e validados, equipamentos calibrados e monitorados e insumos qualificados, validados e inspecionados antes e durante o uso. Isto acarreta, além dos gastos diretos, gastos indiretos especificamente relacionados à garantia da qualidade e da segurança transfusionais, além dos gastos indiretos usuais de qualquer produto ou serviço. Procurando avaliar com maior aproximação estes custos e buscando evitar as distorções das apropriações de custos por rateios, o presente estudo utilizou o sistema de Custeio Baseado em Atividades - ABC, para apurar o custo médio do Módulo de Coleta de sangue total no Hemocentro de Ribeirão Preto - SP, unidade sede, no primeiro semestre de 2006. O maior impacto no custo médio apurado se deveu aos custos monetários diretos, entretanto os custos indiretos não foram desprezíveis. O custo médio obtido para desempenho das atividades que compõem o Módulo de Coleta foi de R$ 35,20, que é 68,75% superior ao valor pago na tabela SIA/SUS para este módulo. A metodologia desenvolvida pode ser aplicada aos outros procedimentos dos serviços de hemoterapia, permitindo a avaliação dos custos de seus processos, evitando desperdícios, aprimorando o seu funcionamento e gerando evidências objetivas que demonstrem os custos reais da hemoterapia de qualidade para as instâncias financiadoras públicas e privadas.The procedures in hemotherapy are complex and expensive. They demand a controlled and validated process. They also require calibrated and monitored equipment and qualified and validated materials, inspected before and during use.

    Full Text Available Introduction: The determination of energy expenditure, considering the physical activity level and health status, is very important to adjust the individuals' nutritional supply. Energy expenditure can be determined by using indirect calorimetry, bioelectrical impedance, doubly labeled water, predictive equations, among others. All these methods have been used in clinical and research areas. However, considering the inconsistence in several research results, there is no consensus yet about the applicability of many of these methods. Objectives: The aim of this review is to describe the components of energy expenditure and the methods for its determination and estimation, summarizing their main advantages and limitations. Results and discussion: Indirect calorimetry and doubly labeled water are considered more accurate methods, but expensive. On the other hand, even though other methods present limitations, they are convenient and less expensive, and can be used with some caution.Introducción: Determinar el gasto energético (GE, considerando la actividad física y el estado de salud, es muy importante para ajustar el cálculo de la necesidad nutricional para cada individuo.

    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. Although the methodology and working procedures of the cost and price auditing in Spain has been developed by the Cost Assessment Group based on the rules of The Defense Contract Audit Agency of the United States (U.S., such methodology has been adapted including some distinctive features that characterize the current model of cost and price auditing in Spain.

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. Los estudiantes procedentes de familias pobres reciben becas estatales que cubren tanto las matrículas como los gastos. _____________________________________________________________________________________________________________________________________________________________________________________ Cette étude évalue les résultats des

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

    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.

    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. In Brazil, the goods and services focused on education may be offered either by public or private. For public entities, the Federal Constitution of 1988 (CF/88 sets out the responsibilities of each level of government in the provision of educational services.

    Full Text Available A hipótese de estabilização da carga tributária (tax-smoothing hypothesis implica: 1 a carga tributária ótima segue um passeio aleatório puro; 2 um superávit orçamentário igual ao valor presente esperado de variações nos gastos do governo. No presente artigo, são realizados testes de passeio aleatório da carga tributária para o período 1970-2002 e usa-se um modelo de vetores auto-regressivos para o período 1970-1997 no caso das finanças públicas do Estado do Rio Grande do Sul. Os testes rejeitam a hipótese de estabilização da carga tributária para o caso em estudo em ambos os períodos. Isto é, as evidências indicam que o governo estadual não se comportou como um tax-smoother.The tax-smoothing hypothesis implies that: 1 the optimal tax rate follows a pure random walk; 2 a budget surplus equal to the expected present value of changes in government expenditures. In this paper random walk tests of tax rate are performed for the period 1970-2002 and use a vector autoregression model to the period 1970-1997 in the case of the state of Rio Grande do Sul public finances. The tests reject the tax-smoothing hypothesis for the case in study for both periods. That is, the evidences show that the state government has not behaved as tax-smoother.

Objetivos: analizar la historia y estado del arte del uso de las ecuaciones predictivas de GER en el paciente quemado crítico, y determinar su validez. Métodos: revisión bibliográfica de estudios y revisiones en español y en inglés entre 1989 y 2013. Resultados: Se han diseñado más de 190 ecuaciones para estimar el gasto energético que pueden ser imprecisas por estar basadas en mediciones con metodología heterogénea y en grupos heterogéneos. Describimos los distintos parámetros que aplican las distintas fórmulas predictivas (factores de estrés y de actividad, superficie corporal quemada, tiempo desde la lesión, masa corporal magra, la influencia de la edad en el cálculo de las necesidades calóricas y las fórmulas más utilizadas en el momento actual. También describimos los artículos que evalúan exactitud de las fórmulas cuando se comparan con mediciones mediante calorimetría indirecta. Conclusiones: Las ecuaciones predictivas son poco precisas en general en el paciente quemado. Hasta que se desarrollen ecuaciones predictivas más precisas, recomendamos calcular los requerimientos nutricionales de los pacientes quemados basándose en la medición del gasto energético por calorimetría indirecta.

  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.

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.

    Introducción: el concepto de “control calorico estricto” surgio para evitar la excesiva y la deficiente nutricion de los pacientes. Objetivo: describir y validar una ecuacion simplificada para el calculo del gasto energetico total (GET) en pacientes criticos con ventilacion mecanica. Métodos: analisis secundario de las mediciones de GET por calorimetria indirecta en pacientes criticos. Los pacientes fueron asignados de forma 2:1 por un paquete estadistico; el primer grupo se empleo para desarrollar la nueva ecuacion predictiva del GET (grupo predictivo) y el segundo para validarla (grupo validacion). La calorimetria indirecta se realizo con tres calorimetros diferentes: la bolsa de Douglas, un computador metabolico y el equipo CalorimetR. Hemos desarrollado la nueva ecuacion predictiva del GET utilizando el GET medido (en kcal/kg/d), como variable dependiente, y como variables independientes los diferentes factores que influyen en el gasto energetico: edad, genero, indice de masa corporal (IMC) y tipo de lesion. Resultados: el grupo de prediccion incluyo 179 pacientes y el de validacion 91 pacientes. La ecuacion predictiva fue: GETEP = 33 - (3 x E) - (3 x IMC) - (1 x G). Donde: E (edad en anos): ≤ 50 = 0; > 50 = 1. IMC (kg / m2): 18,5- 24,9 = 0; 25-29,9 = 1; 30-34,9 = 2; 35-39,9 = 3. G (genero): hombre = 0; mujer = 1. El sesgo (IC del 95%) entre el GET medido y el predicho fue de -0,1 (-1,0 a 0,7) kcal/ kg/dia y los limites de acuerdo (} 2SD) fueron -8,0 a 7,8 kcal/kg/d. El GET por la ecuacion predictiva fue preciso (entre el 85% y el 115%) en el 73,6% de los pacientes. Conclusiones: La nueva ecuacion predictiva fue aceptable para predecir el GET de la mayoria de pacientes criticos con ventilacion mecanica en la practica clinica.

    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 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.

    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.

    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 Algumas variantes da economia política defendem a priorização das políticas públicas voltadas para o atendimento das necessidades básicas dos trabalhadores, desempregados e na miséria. O período em que transcorre o debate é muito expressivo, entre as “jornadas de junho” de 2013-2014, na conjuntura da desaceleração da economia. A crítica econômica defensora da valorização da vida dos trabalhadores encontra respaldo na constatação empírica de que é possível preservar e ampliar as políticas e programas sociais, contra os interesses no crescimento econômico que beneficia o capital e coage a sociedade a submeter-se a corte de gastos sociais, arrochos salariais, desemprego e miséria. Os benefícios ao capital – desonerações fiscais; não tributação do capital rentista e patrimonial; juros da dívida pública, etc. – são as sangrias que desviam as riquezas para ampliar o capital predador e impedem sua canalização para as políticas e programas sociais. Poderosas organizações e minorias sociais servem-se da queda do crescimento para ampliar suas fortunas. Na seleção das fontes deste estudo, as variantes do pensamento são constituídas, fundamentalmente, pela crítica da economia política à economia vulgar, de “monstros” (não homens, mundo das coisas, mercadorias, dinheiro. Entre as variantes mais radicais, está a defesa da ampliação dos gastos sociais, eliminação do superávit primário destinado a pagar juros e a destinação do déficit primário para fins sociais.

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.

    Full Text Available Resumo: Não é novidade que o cidadão brasileiro, como outros vivendo em países democráticos, em média sabem pouco sobre seus governos e sobre as orientações ideológicas da maioria dos candidatos e partidos políticos. No entanto, poucos pesquisadores estudaram de maneira sistemática as conseqüências da falta de informação política para a vida democrática. Segundo alguns, a falta de informação afeta de maneira importante as atitudes políticas dos eleitores. Já para outros, a informação política não é relevante para formação de opiniões. O artigo examina essa questão no Brasil, usando pela primeira vez dados de um experimento conduzido em uma pesquisa de opinião pública realizada em 2004. Mais especificamente, examinamos como a informação sobre o governo federal brasileiro afeta as preferências políticas do cidadão em termos de gastos públicos. No experimento utilizado, alguns participantes receberam informação sobre as fontes de renda do governo federal, suas despesas e políticas públicas, enquanto outros entrevistados não receberam qualquer informação adicional. Os resultados indicam que os participantes que receberam informação política preferem menos impostos e redução nos gastos públicos daqueles que não receberam informação política. Estes resultados têm conseqüências importantes para o estudo do processo democrático, pois indicam que uma cidadania mais informada tem atitudes e preferências políticas distintas de uma menos informada.Abstract: We know that Brazilian citizens, just like those living in other democracies of the world, know very little about politics. We know less, however, about the consequences of political ignorance on the democratic process?

    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. Oitenta e três trabalhadores masculinos participaram neste estudo, com o objetivo de avaliar a carga fisiológica do trabalho de coleta de lixo domiciliar no Município do Rio de Janeiro, Brasil. 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

  5. Estonian total ozone climatology

    Full Text Available The climatological characteristics of total ozone over Estonia based on the Total Ozone Mapping Spectrometer (TOMS data are discussed. The mean annual cycle during 1979–2000 for the site at 58.3° N and 26.5° E is compiled. The available ground-level data interpolated before TOMS, have been used for trend detection. During the last two decades, the quasi-biennial oscillation (QBO corrected systematic decrease of total ozone from February–April was 3 ± 2.6% per decade. Before 1980, a spring decrease was not detectable. No decreasing trend was found in either the late autumn ozone minimum or in the summer total ozone. The QBO related signal in the spring total ozone has an amplitude of ± 20 DU and phase lag of 20 months. Between 1987–1992, the lagged covariance between the Singapore wind and the studied total ozone was weak. The spring (April–May and summer (June–August total ozone have the best correlation (coefficient 0.7 in the yearly cycle. The correlation between the May and August total ozone is higher than the one between the other summer months. Seasonal power spectra of the total ozone variance show preferred periods with an over 95% significance level. Since 1986, during the winter/spring, the contribution period of 32 days prevails instead of the earlier dominating 26 days. The spectral densities of the periods from 4 days to 2 weeks exhibit high interannual variability.

    Introducción: La bacteriemia asociada al catéter (BAC) es una de las complicaciones más importantes en pacientes portadores de un catéter venoso central (CVC) debido a su asociación con un incremento en la mortalidad, morbilidad y gasto sanitario. La administración de nutrición parenteral total (NPT) aumenta el riesgo de aparición de BAC. El objetivo de nuestro estudio fue determinar la tasa de incidencia y los factores de riesgo de BAC en pacientes con NPT hospitalizados en plantas médico-quirúrgicas. Métodos: Estudio observacional, analítico, retrospectivo donde se analizaron a todos los pacientes adultos no críticos que precisaron NPT desde enero de 2010 hasta noviembre de 2011. El punto final clínico fue la BAC. La tasa de incidencia de BAC se calculó en forma de episodios por cada 1.000 pacientes-día de cateterización. Los factores predictivos independientes de BAC se determinaron mediante regresión logística. Resultados: Durante el periodo de estudio precisaron NPT un total de 331 pacientes. La duración media del CVC fue de 12,4 (DE 8,7) días y la NPT fue infundida durante un periodo medio de 10,4 (DE 8,3) días. 47 pacientes presentaron BAC, con una tasa de incidencia de 11,4/1.000 pacientes- día de CVC y de 13,7/1.000 pacientes-día de NPT. Los factores predictores univariantes de aparición de BAC fueron la permanencia del CVC superior a 20 días (OR = 2,48; IC 95%: 1,16-5,26), la duración de la NPT superior a 2 semanas (OR = 4,63; IC 95%: 2,16-9,90) y la presencia de fístulas (OR = 3,08; IC 95%: 1,24-7,63). En análisis multivariante, el único predictor independiente de BAC fue la duración de la NPT (OR para una duración superior a 14 días = 4,9; IC 95%: 2,2-10,9; p < 0,0001). Conclusiones: En pacientes adultos hospitalizados en plantas diferentes a UCI, hemos demostrado que la duración de la infusión de la NPT incrementa el riesgo de BAC. El incremento de riesgo es especialmente marcado, llegando a multiplicarse por 5, con

    Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses. Total lymphoid irradiation is more effective before transplantation than after, but when used after transplantation can be combined with pharmacologic immunosuppression to achieve a positive effect. In some animal models, total lymphoid irradiation induces an environment in which fully allogeneic bone marrow will engraft and induce permanent chimerism in the recipients who are then tolerant to organ allografts from the donor strain. If total lymphoid irradiation is ever to have clinical applicability on a large scale, it would seem that it would have to be under circumstances in which tolerance can be induced. However, in some animal models graft-versus-host disease occurs following bone marrow transplantation, and methods to obviate its occurrence probably will be needed if this approach is to be applied clinically. In recent years, patient and graft survival rates in renal allograft recipients treated with conventional immunosuppression have improved considerably, and thus the impetus to utilize total lymphoid irradiation for its immunosuppressive effect alone is less compelling. The future of total lymphoid irradiation probably lies in devising protocols in which maintenance immunosuppression can be eliminated, or nearly eliminated, altogether. Such protocols are effective in rodents. Whether they can be applied to clinical transplantation remains to be seen.

  6. Algebraic totality, towards completeness

    2009-01-01

    Finiteness spaces constitute a categorical model of Linear Logic (LL) whose objects can be seen as linearly topologised spaces, (a class of topological vector spaces introduced by Lefschetz in 1942) and morphisms as continuous linear maps. First, we recall definitions of finiteness spaces and describe their basic properties deduced from the general theory of linearly topologised spaces. Then we give an interpretation of LL based on linear algebra. Second, thanks to separation properties, we can introduce an algebraic notion of totality candidate in the framework of linearly topologised spaces: a totality candidate is a closed affine subspace which does not contain 0. We show that finiteness spaces with totality candidates constitute a model of classical LL. Finally, we give a barycentric simply typed lambda-calculus, with booleans ${\\mathcal{B}}$ and a conditional operator, which can be interpreted in this model. We prove completeness at type ${\\mathcal{B}}^n\\to{\\mathcal{B}}$ for every n by an algebraic metho...

    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.

    The Upper Cenomanian-Turonian succession exposed at Jardas al'Abid area consists mainly of carbonates with siliciclastic intercalations. This succession is subdivided lithostratigraphically into: Qasr al'Abid (Late Cenomanian) and Al Baniyah (Late Cenomanian-Coniacian) formations. This sequence is relatively rich in macrofossil assemblages especially bivalves, gastropods, and echinoids with rare ammonites. Based on the first occurrence (FO) and last occurrence (LO) of some index species of these macrofossil groups, an integrated biostratigraphic framework has been constructed. The studied Cenomanian-Turonian sequence is subdivided biostratigraphically into three ammonite biozones; Pseudaspidoceras pseudonodosoides Total Range Zone, Choffaticeras segne Total Range Zone, and Coilopoceras requienianum Total Range Zone. Based on the rest of macrofossil assemblages other than the ammonites, eight biozones were recognized; Mecaster batnensis Total Range Zone, Ceratostreon flabellatum-Neithea dutrugei Acme Zone, Costagyra olisiponensis Acme Zone, Pycnodonte (Phygraea) vesicularis vesiculosa Acme Zone, Mytiloides labiatus Total Range Zone = Mecaster turonensis Acme Zone, Rachiosoma rectilineatum-Curvostrea rouvillei-Tylostoma (T.) globosum Assemblage Zone, Radiolites sp.-Apricardia? matheroni Total Range Zone, and Nerinea requieniana Total Range Zone. Most of the proposed biozones are recorded for the first time from Libya. The integration among these biozones as well as local and inter-regional correlation of the biozones have been discussed. The stage boundaries of the studied stratigraphic intervals are discussed, where the Cenomanian/Turonian boundary is delineated at the last occurrence (LO) of Pseudaspidoceras pseudonodosoides (Choffat), while the Turonian/Coniacian boundary is delineated arbitrary being agree with the LO of the Turonian fauna.

Assim, o objetivo deste trabalho foi avaliar o GE e o NAF da população adulta (> 20 anos do município de Niterói, RJ. Para a obtenção do tempo de duração das atividades cotidianas, usou-se um questionário de orçamento do tempo das atividades cotidianas.

O RE usando o valor de NAF de 1,40 foi o que melhor estimou o GETD na população em todas as categorias de estado nutricional. Parece ser prudente utilizar valores menores de NAF para a estimativa dos RE na população adulta de Niterói. Fica evidente a necessidade de se obter mais dados de CE de atividades para, junto com estimativas adequadas da TMB, se poder determinar os RE da população brasileira.The accurate assessment of energy expenditure (EE and of the physical activity level (PAL is important for establishing the energy requirements (ER of populations.

    Full Text Available Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients’ quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

    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.

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. Ante la ausencia de una regulación sobre la cuestión hasta fechas muy recientes (Directiva 2011/24/UE del Parlamento Europeo y del Consejo de 9 de marzo de 2011, relativa a la aplicación de los derechos de los pacientes en la asistencia sanitaria transfronteriza la labor interpretativa efectuada por el órgano jurisdiccional comunitario ha sido determinante para comprender el alcance de esta materia, declarando que solamente respecto de aquellas prestaciones en las que efectivamente pudiera existir una justificación derivada de la sostenibilidad del sistema público, como sucede en las prestaciones sanitarias hospitalarias, procederá la exigencia de una autorización previa. Por el contrario, cuando no se requiere el empleo de materiales pesados y onerosos, la exigencia del requisito de autorización previa resulta contraria al actual art. 56 TFUE (antiguo art. 49 TCE, como determina la sentencia comentada, de 27 de octubre de 2011, Comisión contra Portugal, C-255/09.

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

    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

    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.

    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.

They are able to use a number of adjustment mechanisms to the knowledge about themselves - ranging from symbolic escape to open resistance against the imposed image about them; to obedience, and we were interested to understand the (supposed complex dynamic of identity (re-building in, so-called, special or forensic patients. In order to understand this process and attempting to discover, besides the manifest also the latent layer of the story about self, the local, or personal, identity understanding was examined.

  13. Total ankle joint replacement.

    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

    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

    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

    Evaluation and assessments of informal education programs small or large such as science museum traveling exhibits interpretive kiosks hands-on activities and very large public programs have been challenging due to the diverse nature of objectives setups and expected outcomes of these programs. Almost all institutions that develop and present such programs include in their staff evaluation specialists. However for very large public outreach efforts which include participation of multi institutions located across the country larger evaluation groups/institutions can contribute more objective and extensive evaluation and assessment instruments that will help to identify weather the program was successful and if the learning objectives were achieved. Total Solar Eclipse 2001 event was participated by approximately 42000 people at museums science centers and Planetaria all over the world. I will share with you the results of an evaluation of this event that was surveyed and reported by an independent evaluation company. I will expand further on the properties of this program that helps to determine weather the program was successful or not including the discussion on how personal interest in the content publicity connectivity to a group educational as well as entertainment value and the challenges of using high technology can define success.

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.

  1. First principles calculation of ac conductance for Al-BDT-Al and Al-Cn-Al systems

    Full Text Available We perform first-principles calculation to investigate the dynamic conductance of atomic wires of the benzenedithiol (BDT as well as carbon chains with different length in contact with two Al(100 electrodes (Al-Cn-Al. Our calculation is based on the combination of the non-equilibrium Green's function and the density functional theory. For ac conductance, there are two theories that ensures the current conservation: (1. the global formula which is a phenomenological theory that partitions the total displacement current into each leads so that the current is conserved.(2. the local formula which is a microscopic theory that includes Coulomb interaction explicitly so that the current is conserved automatically. In this work, we use the local formula to calculate the dynamic conductance, especially the emittance. We give a detailed comparison and analysis for the results obtained from two theories. Our numerical results show that the global formula overestimates the emittance by two orders of magnitude. We also obtain an inequality showing that the emittance from global formula is greater than that from local formula for real atomic structures. For Al-Cn-Al structures, the oscillatory behavior as the number of carbon chain N varies from even to odd remains unchanged when local formula is used. However, the prediction of local formula gives rise to opposite response when N is odd (inductive-like as compared with that of global formula. Therefore, one should use the local formula for an accurate description of ac transport in nanoscale structures. In addition, the ‘size effect’ of the ac emittance is analyzed and can be understood by the kinetic inductance. Since numerical calculation using the global formula can be performed in orbital space while the local formula can only be used in real space, our numerical results indicate that the calculation using the local formula is extremely computational demanding.

  6. 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

    [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.

    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.

    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.

    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.

    Objective To investigate the antitumor effects of tumor vaccine produced by autologous dendritic cells transfected of allogeneic osteosarcoma total RNA through electroporation in tumor-bearing rats model. Methods In the present study, the tumor vaccine was got by transfecting UMRI08 cells total RNA to SD rat bone marrow-derived DCs through electroporation, and was applied to in tumor-bearing rats model and the specific antitumor effects of the tumor vaccine were observed. Then CTL activity was evaluated one week after the first immunization of SD rats with electroporated DCs. Results The immunization using au-tologous DCs electrotransfected with allogeneic osteosarcoma total RNA induced UMRlO6-specific CTL re-sponses which were statistically significant. In in vivo experiments, 80% of the rats immunized with allo-geneic osteosarcoma RNA transfected to DCs were typically able to reject tumor challenge and remained tu-mor-free. Vaccinated survivors developed long immunological memory and were able to reject a subsequent rechallenge with the same tumor cells but not a syngeneic unrelated tumor line. Conclusion The present study provides valid evidence of integration of autologous rat DCs electroporated with allogeneie tumor cell derived total RNA and reveales the effective potential of activation of CTLs. The research also confirmes the therapeutic effectiveness of positive immunization through corresponding animal experiment. This technique and its products may thus represent a promising strategy for DC-based immunotherapy of patients with os-teosarcoma.%目的 本研究旨在探讨异体大鼠骨肉瘤细胞RNA电转染树突状细胞(dendritic cells,DC)瘤苗在大鼠肿瘤动物模型诱导的抗骨肉瘤免疫学效应.方法 本研究采用UMR108细胞RNA通过电穿孔的方法 转染至SD大鼠骨髓来源的DCs制备瘤苗.将该瘤苗应用于骨肉瘤荷瘤大鼠,观察其特异性抗肿瘤效应,并对瘤苗诱导的细胞毒性T淋巴细胞(cytotoxic T

    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.

  18. Cogema acquires TOTAL's uranium assets

    On April 28, France's nuclear fuel cycle conglomerate Cogema and petroleum group TOTAL announced a plan in which Cogema will assume ownership of TOTAL's uranium assets worldwide, and as part of the deal, each firm will acquire shares of the other. On June 2, the agreement will be submitted to shareholders and, assuming it is approved, will go into effect this year. The agreement calls for TOTAL to acquire a 10.8-percent share in Cogema, thus becoming its first private sector shareholder, by underwriting a reserve capital increase of FF1.5 billion (approximately US$283 million). In return, Cogema will pay FF2.52 billion for approximately 4.3 percent of TOTAL, as part of a reserve capital increase totalling FF4.07 billion

    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 investigated the structural, electronic, and magnetic properties of AlN/VN/AlN and VN/AlN/VN interlayers in the wurtzite structure, via first-principles calculations using the psuedopotential method within density functional theory (DFT) as implemented in the Quantum ESPRESSO code. The total energy calculation showed that the VN/AlN/VN interlayer is energetically more favorable than the AlN/VN/AlN one. Analysis of the density of states showed that the interlayers exhibit a metallic behavior that essentially comes from the hybridization and polarization of states V-d and N-p across the Fermi level. The interlayers exhibit magnetic properties, with a magnetic moment of 4μβ/cell. Due to these properties, the superlattices can potentially be used in the field of spintronics.

    To make sure the intermediate products of the carbothermic reduction of Al2O3 process, such as Al4CO4, Al2CO and Al4C3, and the interaction of AlCl, AlCl2, AlCl3 with Al4CO4, Al2CO and Al4C3, respectively, thermodynamic analyses were used to study the chloride reaction production of them under the vacuum situation. The stable structures and electronic properties of AlCl, AlCl2 and AlCl3 adsorbed on Al4CO4, Al2CO and Al4C3 were calculated by first-principles calculations by the CASTEP module in the Materials Studio program. The results show that the AlCl3 and AlCl2 molecules have decomposed on the plane of Al4C3 (001), while there are no obvious decomposition of AlCl3 and AlCl2 on Al4CO4 (001) and Al2CO (001) planes. The adsorption of AlCl on the Al4CO4 (001) and Al2CO (001) planes is stronger than that on the Al4C3(001) plane. The interaction strength of AlCl3, as well as AlCl2, with Al4CO4, Al2CO and Al4C3 is in the sequence of Al4CO4Al2CO>Al4C3.

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.

    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.

    Soil acidification promotes Al release from minerals and parent bedrocks; it also affects Al mobilization and speciation. Speciation of KCl extractable and water-extractable Al in forest soils was done by means of HPLC/IC method. Species Al3+ were the most abundant Al forms in the KCl extracts (around 93%). Prevailing Al forms (more than 70%) in aqueous extracts were Al(X)1+, [i.e., Al(OH)2+, Al(SO4)+, AlF2+, Al(oxalate)+, Al(H-citrate)+, etc.] species. It is assumed that most of KCl and water-extractable Al is bound in soil sorption complex (i.e., highly dispersed colloidal fraction of the soil solid phase creating negative charge) where majority of Al exists in the form of Al3+ species. The ECEC values, total carbon content and parameters related to soil organic matter composition (N and S content) have apparent effect on Al speciation. The most toxic Al3+ species are more concentrated in the B horizons compared to the A and E horizons. Aqueous extracts simulate Al release to soil solution under normal conditions; it can thus exhibit the actual Al toxicity. On the other hand, KCl extraction describes a potential threat for case of strong disturbance of natural soil conditions. PMID:16095711

  2. 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.

    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.

    @@ 1Introduction Mycalamides A (1a) and B (1b) are potent antiviral compounds from a New Zealand sponge of the genus Mycale. Apart from their antitumor property, mycalamide A (1a) exhibits immunosuppressive action by blocking T-cell activation in mice and is significantly more potent than FK-506 and cyclosporine A. Because of their intriguing biological activity, unique structures and scarce supply of these natural products, mycalamides A (1a) and B (1b) have attracted considerable attention as target molecules for total synthesis, and total, formal, or partial syntheses of this family of compounds have been reported[1,2].

  8. 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

Material y métodos: a 66 mujeres (índice de masa corporal 44,7 ± 4,9 kg/m²; edad 35,6 ± 10,3 años se les realizó calorimetría indirecta con monitor metabólico Deltatrac (Datex Inst., Finlandia, antes de someterse a cirugía bariátrica. 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. Conclusión: En la serie pacientes con obesidad severa y mórbida evaluadas, la ecuación de Mifflin y la Estimación Rápida otorgan el menor error de estimación del gasto energético de reposo en mujeres.

    Full Text Available Intrathoracic hernias after total gastrectomy are rare. We report the case of a 78-year-old man who underwent total gastrectomy with antecolic Roux-Y reconstruction for residual gastric cancer. He had alcoholic liver cirrhosis and received radical laparoscopic proximal gastrectomy for gastric cancer 3 years ago. Early gastric cancer in the remnant stomach was found by routine upper gastrointestinal endoscopy. We initially performed endoscopic submucosal dissection, but the vertical margin was positive in a pathological result. We performed total gastrectomy with antecolic Roux-Y reconstruction by laparotomy. For adhesion of the esophageal hiatus, the left chest was connected with the abdominal cavity. A pleural defect was not repaired. Two days after the operation, the patient was suspected of having intrathoracic hernia by chest X-rays. Computed tomography showed that the transverse colon and Roux limb were incarcerated in the left thoracic cavity. He was diagnosed with intrathoracic hernia, and emergency reduction and repair were performed. Operative findings showed that the Roux limb and transverse colon were incarcerated in the thoracic cavity. After reduction, the orifice of the hernia was closed by suturing the crus of the diaphragm with the ligament of the jejunum and omentum. After the second operation, he experienced anastomotic leakage and left pyothorax. Anastomotic leakage was improved with conservative therapy and he was discharged 76 days after the second operation.

    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.

    Full Text Available In the present investigation, the static immersion corrosion behavior of Al/Al2O3 and Al/SiC nanocomposites in 1 M HCl acidic solution was evaluated. The nanocomposites were fabricated using conventional powder metallurgy (P/M route. The effect of nanoparticulates size and volume fraction on the corrosion behavior of nanocomposites was studied. The durations of the corrosion tests ranged from 24 to 120 hours and the temperatures of the solution ranged from ambient to 75 ºC. The corrosion rates of the nanocomposites were calculated using the weight loss method. The results showed that both Al/SiC and Al/Al2O3 MMNCs have lower corrosion rates than the pure Al matrix. Such behavior was noticed at both ambient and higher temperatures. Generally, the Al/Al2O3 nanocomposites exhibited lower corrosion rates than the Al/SiC nanocomposites. The Al/Al2O3 (60 nm nanocomposites exhibited the highest corrosion resistance among all the investigated nanocomposites. The corrosion rate was found to be reduced by increasing of the exposure time and the volume fraction of the nanoparticulates, while it was found to be increased by increasing of the nanoparticulates size and the solution temperature.

    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

    Thongrattanasiri, Sukosin; de Abajo, F Javier Garcia

    2011-01-01

    We demonstrate that 100% light absorption can take place in a single patterned sheet of doped graphene. General analysis shows that a planar array of small lossy particles exhibits full absorption under critical-coupling conditions provided the cross section of each individual particle is comparable to the area of the lattice unit-cell. Specifically, arrays of doped graphene nanodisks display full absorption when supported on a substrate under total internal reflection, and also when lying on a dielectric layer coating a metal. Our results are relevant for infrared light detectors and sources, which can be made tunable via electrostatic doping of graphene.

    The radiology of total hip replacement (THR) and its complications is reviewed in conjunction with a long-term follow-up study on 402 patients with 501 prostheses. The indications, contraindications, biomechanics, and operative management of these patients is discussed. Clinical complications such as deep vein thrombosis, pulmonary embolism, and hemorrhage are mentioned. Postoperative infections including granulomatous pseudotumors, dislocations and fractures, true loosening of the prosthesis, and heterotopic bone formation (HBF) are discussed and illustrated. The importance of differentiating the lucent line from true loosening is stressed. Mechanical and other clinical complications which are largely ignored by radiologists are also discussed. The uses of arthrography and bone scanning are included.

    Nitidasin is a pentacyclic sesterterpenoid with a rare 5-8-6-5 carbon skeleton that was isolated from the Peruvian folk medicine "Hercampuri". It belongs to a small class of sesterterpenoids that feature an isopropyl trans-hydrindane moiety fused to a variety of other ring systems. As a first installment of our general approach toward these natural products, we report the total synthesis of the title compound. Our stereoselective, convergent route involves the addition of a complex alkenyl lithium compound to a trans-hydrindanone, followed by chemoselective epoxidation, ring-closing olefin metathesis, and redox adjustment.

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

    KAUST Repository

    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.

    2013-11-01

    Total hip and knee arthroplasty are surgical procedures usually performed in older adults aged 65-70 years and more, who suffer from arthritic joint degeneration, in order to relieve pain and improve functioning. In the past decade there have been more and more documentations of younger people, 50-60 years old and even less, who expect to participate in physical activity following these procedures. The trend today is to recommend activities which exert mild pressure on the implants such as swimming, cycling, golf, bowling, walking and cycling. It is not recommended to participate in sports activities that place greater pressure on the implants such as soccer, football, volleyball, handball, basketball, hockey and jogging. Such high-stress activities may cause early loosening of implants, as described in the article by Keren et al. in this issue: "Sport activity after hip and knee arthroplasty". PMID:24416821

    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.

    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

    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.

  9. Total probabilities of ensemble runoff forecasts

    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

    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 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

Las cartas deben permitir el intercambio de opiniones y formas de pensar y analizar los problemas planteados entre los autores y los lectores. En ocasiones una serie de cartas motivadas por un artículo original puede ser tan o más interesante como el artículo que generó la correspondencia. Las cartas son también un formato adecuado para comunicar un hecho novedoso de una observación clínica juiciosa no descrita antes. Un ejemplo de ello es la carta de un gineco-obstetra australiano cuando informó a Lancet los primeros efectos adversos informados de la talidomida. Colombia Médica, a pesar de mantener vigente esta sección, no ha sido muy afortunada en establecer una buena cultura del envío de cartas al editor. Pero últimamente han llegado juiciosas observaciones a las cuales se les ha dado prioridad en su publicación. Toda carta que comenta los hallazgos de un artículo es enviada a los autores para su respuesta, porque ello genera el debate académico buscado, y luego se publican, tanto la carta como su respuesta. El Estilo Vancouver recomienda que la carta y su respuesta deban ser breve, no pasar de dos o tres párrafos y contener sólo cuatro o cinco referencias.

    Full Text Available BACKGROUND: Hysterectomy is a common gynaecological surgery which can be done by abdominal, vaginal or laparoscopic routes or with robotic assistance. Although there were concerns regarding the safety of laparoscopic surgery, a newer technique when compared with abdominal hysterectomy, it is now being reco gnized as a safe procedure in the hands of an experienced surgeon. AIMS: This study was done to compare the intra - operative and post - operative parameters of abdominal and laparoscopic hysterectomy. SETTINGS AND DESIGN: This study was done at JSS Hospital, Mysore between June 2013 and September 2014. It is a retrospective study . MATERIALS AND METHOD S: Patients admitted in the Department of Obstetrics and Gynaecology at JSS Hospital, JSS University, Mysore, with an indication for total abdominal hysterectomy( TAH or total laparoscopic hysterectomy(TLH for benign pathology from June 2013 to September 2014 were included in the study. Exclusion criteria were suspicion of malignancy, vaginal prolapse higher than first degree and those undergoing laparoscopic assi sted vaginal hysterectomy. Baseline characteristics, intraoperative and postoperative parameters were compared between the two groups. STATISTICAL ANALYSIS : The data were analyzed using independent T test, Chi square test and Mann Whitney test. A p value o f <0 . 05 was accepted as significant. RESULTS: The mean time taken to perform TLH was significantly longer, i.e. 113.46 minutes compared with TAH, i.e. 70.44 minutes, with the p value being <0.0001. But the duration of stay in the hospital was shorter for t he women undergoing TLH, mean duration being 3.74 days as opposed to 7.65 days in women undergoing TAH. This difference was also statistically significant with p value being <0.0001. Also, women undergoing TAH required more analgesic doses (mean 3.29 than those undergoing TLH (mean 1.36 and this difference was also statistically significant. CONCLUSION: Although TLH took a

    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.

  19. Demand: a total nuclear disarmament

    International Nuclear Information System (INIS)

    This bibliographical note presents a book, in which the authors make a plea for a total nuclear disarmament. They think that humanity cannot be found in competition, but in emulation, and examine how we can get rid of the nuclear bomb. They discuss the background of nuclear energy, state that nuclear weapons have always been useless and extremely dangerous, consider arms race as crazy and as a crime against humanity, recall that nuclear weapons already made numerous victims (Hiroshima, Nagasaki, nuclear tests), that they are a sword of Damocles over 7 billions human beings, that nuclear winter would be an apocalypse, that the Non Proliferation Treaty is a decoy. They discuss the political role of nuclear weapons, and outline that the only solution is their abolition. They discuss what has already been done and what is still to be done, and formulate a strategy for the future

    2013-04-01

    TVD solves the magnetohydrodynamic (MHD) equations by updating the fluid variables along each direction using the flux-conservative, second-order, total variation diminishing (TVD), upwind scheme of Jin & Xin. The magnetic field is updated separately in two-dimensional advection-constraint steps. The electromotive force (EMF) is computed in the advection step using the TVD scheme, and this same EMF is used immediately in the constraint step in order to preserve \\Downtriangle B=0 without the need to store intermediate fluxes. The code is extended to three dimensions using operator splitting, and Runge-Kutta is used to get second-order accuracy in time. TVD offers high-resolution per grid cell, second-order accuracy in space and time, and enforcement of the \\Downtriangle B=0 constraint to machine precision. Written in Fortran, It has no memory overhead and is fast. It is also available in a fully scalable message-passing parallel MPI implementation.

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.

    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.

  3. 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.

  5. 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.

    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.

    In FeSiAl alloys, when Si substitutes for Al, important changes take place in the magnetism as well as in the structural properties. Alloys in the two composition series Fe{sub 75}Al{sub 25-x}Si{sub x} (x=0, 7.5, 12.5, 17.5, 25) and Fe{sub 70}Al{sub 30-x}Si{sub x} (x=0, 9, 15, 21, 30) were prepared by induction melting; afterwards they were crushed and then annealed in order to recover the DO{sub 3} stable phase. The deformed FeAl samples show larger lattice parameters than the ordered ones; however, this difference ({delta}a) decreases when Si substitutes for Al until it becomes zero (i.e. until the ordered samples and the deformed ones have the same lattice parameters). This trend is the same for both sample series and does not depend on the Fe content of the alloy. However, the magnetization has a different behaviour depending on the Fe content. For deformed Fe{sub 75}Al{sub 25-x}Si{sub x} alloys the saturation magnetization decreases with increasing Si content while for Fe{sub 70}Al{sub 30-x}Si{sub x} deformed alloys the saturation magnetization has a plateau in which the saturation magnetization values do not vary.

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)

    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.

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.

    Stiffness after total knee arthroplasty (TKA) adversely affects outcome and impacts patient function. Various risk factors for stiffness after TKA have been identified, including reduced preoperative knee range of motion, history of prior knee surgery, etiology of arthritis, incorrect positioning or oversizing of components, and incorrect gap balancing. Mechanical and associated causes, such as infection, arthrofibrosis, complex regional pain syndrome, and heterotopic ossification, secondary gain issues have also been identified. Management of stiffness following TKA can be challenging. The condition needs to be assessed and treated in a staged manner. A nonsurgical approach is the first step. Manipulation under anesthesia may be considered within the first 3 months after the index TKA, if physical therapy fails to improve the range of motion. Beyond this point, consideration should be given to surgical intervention such as lysis of adhesions, either arthroscopically or by open arthrotomy. If the cause of stiffness is deemed to be surgical error, such as component malpositioning, revision arthroplasty is indicated. The purpose of this article is to evaluate the various aspects of management of stiffness after TKA.

    A concise asymmetric total synthesis of (-)-vindoline (1) is detailed based on a tandem intramolecular [4+2]/[3+2] cycloaddition cascade of a 1,3,4-oxadiazole inspired by the natural product structure, in which the tether linking the initiating dienophile and oxadiazole bears a chiral substituent that controls the facial selectivity of the initiating Diels-Alder reaction and sets absolute stereochemistry of the remaining six stereocenters in the cascade cycloadduct. This key reaction introduces three rings and four C-C bonds central to the pentacyclic ring system setting all six stereocenters and introducing essentially all the functionality found in the natural product in a single step. Implementation of the approach also required the development of a unique ring expansion reaction to provide a six-membered ring suitably functionalized for introduction of the Delta (6, 7)-double bond found in the core structure of vindoline and defined our use of a protected hydroxymethyl group as the substituent used to control the stereochemical course of the cycloaddition cascade.

    Patients begin to formulate their expectations of the postoperative hospitalization during the preadmission program. The challenge is to better understand the factors patients consider when formulating judgments about the quality of preadmission education.

    Patients begin to formulate their expectations of the postoperative hospitalization during the preadmission program. The challenge is to better understand the factors patients consider when formulating judgments about the quality of preadmission education. For example, it may be that perceptions of the preadmission program are influenced by what patients believe about their postoperative pain and functional abilities. Specific attention needs to be given both preoperatively and postoperatively to instructing patients on realistic expectations for recovery.

    This paper presents a finite element thermal model for similar and dissimilar alloy friction stir spot welding (FSSW). The model is calibrated and validated using instrumented lap joints in Al-Al and Al-Fe automotive sheet alloys. The model successfully predicts the thermal histories for a range of process conditions. The resulting temperature histories are used to predict the growth of intermetallic phases at the interface in Al-Fe welds. Temperature predictions were used to study the evolution of hardness of a precipitation-hardened aluminum alloy during post-weld aging after FSSW.

    Introducción. El tratamiento del bocio multinodular beningo (BMNB) es motivo de continuo debate en las últimas décadas pese a la evidencia de que la tiroidectomía total (TT) está relacionada a una reducción significativa en la recurrencia de la enfermedad y a una mínima morbilidad en manos entrenadas. Objetivo. Determinar la recurrencia del BMNB al cabo de 10 años en 100 pacientes tratados con TT y evaluar las complicaciones relacionadas a la técnica.Diseño. Prospectivo no randomizado.Material y métodos. Desde marzo del 1999 a marzo del 2001, cien pacientes, 95 del sexo femenino, con un promedio de edad de 42,4 años (rango: 23-67), fueron sometidos a una TT por padecer un BMNB, el cual fue confirmado por la ecografía cervical, la que además sirvió de guía para realizar la punción aspiración con aguja fina (PAAF). En todos los casos se realizó un laringoscopía inderecta pre y post postquirúrgica. Resultados. El tiempo operatorio promedio fue de 49 minutos (rango: 35-58). Registramos una parálisis recurrencial (1%) y cinco hipoparatiroidismos (5%), ambos transitorios y ningún caso definitivo. Todos los pacientes fueron dados de alta antes de las 24 horas de la cirugía. No objetivamos ninguna recurrencia del BMNB en un período de seguimiento de más de 10 años.Conclusión. La TT es el tratamiento elección del BMNB, por ser un procedimiento eficaz, seguro, con mínimas tasas de complicaciones y por evitar o reducir significativamente la recurrencia de esta enfermedad.

  4. Nordic Seas total alkalinity data in CARINA

    2009-08-01

    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.

  5. Site preference of Zr in Ti3Al and phase stability of Ti2ZrAl

    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 (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.

    Acid mine drainage (AMD) severely impacts the water chemistry of a receiving resource, changing the occurrence, speciation and toxicity of metals such as Aluminium (Al). The toxicity of Al is determined by its speciation represented by the labile monomer Al fraction or Al(3+). The purpose of the study was to combine fractionation and Visual MINTEQ speciation to calculate the effect of AMD altered water chemistry on Al speciation and Al(3+) concentration. Water in rivers impacted by AMD presented with monomeric Al (Almon) concentrations between 0.35 and 15.37mgL(-)(1) which existed almost exclusively in the toxic labile form (98%). For the reference site, Almon was less than 2% (10μgL(-1)), suggesting significantly lower Al toxicity. Principal component analysis plots illustrated that labile Al was directly related to the total Al and iron concentrations and strongly influenced by parameters such as pH, electrical conductivity, sulphate and dissolved organic carbon. Visual MINTEQ modelling was used to determine the primary Al species distribution. The dominant form of Al in AMD impacted water was AlSO4(+), which increased proportionally with the sulphate and Al(3+) concentration. Heavily impacted areas, presented with an average of 1mgmL(-)(1) Al(3+), which poses a potential human health risk. A novel centrifugal ultrafiltration method was investigated as an alternative to determining Almon to simplify the speciation of Al. Monomeric and centrifugal ultrafiltrated (<10kD) Al fractions were significantly similar (p=0.74), suggesting that ultrafiltration may present a time, energy and cost saving alternative to organic extraction of Almon.

    The crystal structure of new self-assembled InSb/AlAs and AlSb/AlAs quantum dots grown by molecularbeam epitaxy has been investigated by transmission electron microscopy. The theoretical calculations of the energy spectrum of the quantum dots have been supplemented by the experimental data on the steady-state and time-resolved photoluminescence spectroscopy. Deposition of 1.5 ML of InSb or AlSb on the AlAs surface carried out in the regime of atomic-layer epitaxy leads to the formation of pseudomorphically strained quantum dots composed of InAlSbAs and AlSbAs alloys, respectively. The quantum dots can have the type-I and type-II energy spectra depending on the composition of the alloy. The ground hole state in the quantum dot belongs to the heavy-hole band and the localization energy of holes is much higher than that of electrons. The ground electron state in the type-I quantum dots belongs to the indirect X XY valley of the conduction band of the alloy. The ground electron state in the type-II quantum dots belongs to the indirect X valley of the conduction band of the AlAs matrix.

    Porous TiAl intermetallic compound, as a novel substitute for current inorganic porous material, offsets the shortages of both ceramics and metals. The environmental corrosion resistance of porous TiAl intermetallic compound was investigated. The kinetic equation for the cyclic oxidation of porous TiAl alloy at 600 ℃ is determined to be Δm2=1.08×10-5t. After total oxidation of 140 h, porous TiAl intermetallic compound shows more stability of pore structure and the mass gain of TiAl alloy is 0.042 g/m2, which is only 10.6% that of porous 316L stainless steel. The kinetic equation for the cyclic corrosion behavior of porous TiAl alloy in hydrochloric acid with pH=2 at 90 ℃ is determined to be Δm2=5.41×10-5t-2.08×10-4. After 50 h exposure, the mass loss of TiAl alloy is 0.049 g/m2, which is only 14.8% and 5.57% that of porous Ti and stainless steel, respectively. The kinetic equation in hydrochloric acid with pH=3 is determined to be Δm2=2.63×10-6t-3.72×10-6.

    We investigated the effect of InAlAs layer thickness on exciton-spin relaxation and optical properties of In0.62Al0.38As/Al0.67Ga0.33As QDs. The luminescence properties and carrier dynamics of QDs were studied by the temperature-dependent photoluminescence (PL) and pump-probe measurements. As the total amount of deposited In0.62Al0.38As alloy increased, the central position of the low-energy PL signal decreases, while its full width at half maximum (FWHM) increases. A monotonous redshift of the PL peak was observed with increasing temperature due to the electron-phonon scattering. From the pump-probe measurement, the spin relaxation time decreases with the monolayers at higher temperatures, in agreement with the phonon energy determinate by PL measurements.

    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.

    Full Text Available This article analyzes institutions and processes yet understudied in the state level of government: the role of public bureaucracies in the formulation of social policies, as well as the connections between social spending and party and electoral dynamics. The analysis concentrates on a program of school construction and reform implemented in the state of Bahia from 1999 to 2002. To assess the extent in which the State Education Department relied on party-political criteria to allocate investments, we develop a logistic regression model. We also rely on a series of interviews with qualifi ed informants to unveil the internal dynamics of the Education Department. Our conclusion reveals that the results of the expansion program for the secondary and fundamental schooling were shaped by the confl ict between technical and political staff, which in turn promoted the coexistence of distinct rationalities within the education bureaucracy. Keywords: State government. Decentralization. Bureaucracy. Educational policy. O trabalho analisa processos e instituições ainda pouco estudados na esfera estadual de governo: o papel da burocracia na formulação de políticas sociais, bem como as conexões entre o gasto público social e a dinâmica eleitoral e partidária. A análise enfoca o programa de expansão e melhoria da rede física das escolas públicas estaduais de nível fundamental e médio implantado na Bahia entre os anos de 1999 e 2002. Para avaliar em que medida a Secretaria Estadual de Educação teria adotado critérios político-partidários de alocação de recursos, o trabalho desenvolve um modelo de regressão logística multivariada. O artigo se vale ainda de entrevistas realizadas junto a informantes qualifi cados para desvelar a dinâmica interna da Secretaria. Conclui-se que os resultados do programa de expansão do ensino fundamental e médio foram condicionados pelo confl ito entre quadros técnicos e políticos, que por sua vez

    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.

    We demonstrate a local strain sensing method for nanostructures based on metallic Al tunnel junctions with AlOx barriers. The junctions were fabricated on top of a thin silicon nitride membrane, which was actuated with an AFM tip attached to a stiff cantilever. A large relative change in the tunneling resistance in response to the applied strain (gauge factor) was observed, up to a value 37. This facilitates local static strain variation measurements down to ~10^{-7}.

    Periodic discharges of high concentrations of aluminium (Al) causing fish kills and other adverse effects occur worldwide in waterways affected by coastal lowland acid sulfate soils (CLASS). The exchangeability - a metal's ability to readily transfer between the soil solid- and solution-phases - of Al in these soils is therefore of particular importance as it has implications for metal transport, plant availability and toxicity to living organisms. In the present study, the concentrations of isotopically exchangeable Al (E values) were measured in 27 CLASS and compared with common salt extractions (i.e. KCl and CuCl2) used to estimate exchangeable soil pools of Al. E values of Al were high in the soils, ranging from 357 to 3040 mg·kg(-1). Exchangeable concentrations estimated using 1 M KCl were consistently lower than measured E values, although a reasonable correlation was obtained between the two values (E=1.68×AlKCl, r(2)=0.66, n=25). The addition of a 0.2 M CuCl2 extraction step improved the 1:1 agreement between extractable and isotopically exchangeable Al concentrations, but lead to significant mobilisation of non-isotopically exchangeable Al in surficial 'organic-rich' CLASS having E values<1000 mg·kg(-1). It was concluded that currently used (i.e. 1 M KCl) methodology severely underestimates exchangeable Al and total actual acidity values in CLASS and should be corrected by a factor similar to the one determined here.

    antecedentes: la alta prevalencia de artrosis en los países occidentales, el elevado costo de las intervenciones de artroplastia de cadera y rodilla y las amplias variaciones en la práctica médica generan gran interés por comparar los costos asociados antes y después de la cirugía. Objetivo: conocer el costo de las intervenciones de reemplazo total de cadera y rodilla durante la estancia hospitalaria y al año de seguimiento posterior al alta. material y métodos: estudio multicéntrico y prospectivo efectuado en 15 hospitales de tres comunidades autónomas. La relación entre las variables independientes con el costo de la estancia y costo post-alta, se analizó con modelos multinivel y para agrupar los casos se utilizó la variable "hospital." Las variables independientes fueron: edad, sexo, índice de masa corporal, calidad de vida prequirúrgica (cuestionarios ED-5D, SF-12 y Womac), intervención (cadera-rodilla), índice Charlson, complicaciones, número de camas y dependencia económico-institucional del hospital, comunidad autó-noma y presencia de cuidador. Resultados: el costo promedio por paciente, sin incluir el costo de la prótesis, fue de 4,734 Euros ± 2,136 y el costo del seguimiento post alta de 554 Euros ± 509. Si se incluye el costo de la prótesis, al final del año el costo total asciende a 7,645 Euros ± 2,248. Conclusiones: existe un margen considerable en la reducción de los costos de estancia; más de 44% de la variabilidad observada no está determinada por las condiciones clínicas de los pacientes sino por el comportamiento de los centros hospitalarios.

    RiassuntoLo scopo dello studio è quello di verificare l’incidenza del timore postoperatorio ai movimenti nei pazienti sottoposti ad artroplastica totale del ginocchio (TKA) e di determinare l’associazione di questo timore con i provvedimenti da adottare. Lo studio prospettico riguarda 78 pazienti sottoposti ad TKA primaria per osteoartrite. L’incidenza di timore al movimento è stata detenninata con l’uso della Tampa Scale of Kinesiophobia (TSK). I pazienti sono stati valutati in tre fasi temporali: 2 settimane. 4 settimane e 6 mesi dopo l’intervento chirurgico. In tutte e tre le fasi sono stati valutati il dolore e l’entità della flessione, mentre l’aspetto funzionale è stato preso in considerazione soltanto sei mesi dopo l’intervento, secondo la Oxford knee score 1. Il timore al movimento è stato registrato in 17 pazienti (21,8%). Quelli con maggiore entità di timore hanno dimostrato di conseguire risultati significativamente meno buoni in termini di dolore, grado di flessione e funzionalità rispetto a quelli con limitata paura. Miglioramento del dolore e della flessione sono stati progressivamente conseguiti nel tempo in entrambi i gruppi, ma i risultati migliori vengono raggiunti nel gruppo con minore paura al movimento. Lo studio ha dimostrato che la paura postoperatoria alla motilità si associa significativamente con il dolore, l’entità della flessione e la funzionalità del ginocchio. Altri Autori haImo rilevato che il timore preoperatorio alla motilità del ginocchio fa prevedere limitazioni funzionali postoperatorie. In conclusione il timore della motilità si rileva in una significativa proporzione dei pazienti dopo TKA e si associa con gonalgia, e minore flessione e funzionalità, e dunaue questa paura rappresenta un richio di scarsi risultati dopo artroplastica totale del ginocchio.

  18. A united refinement technology for commercial pure Al by Al-10Ti and Al-Ti-C master alloys

    International Nuclear Information System (INIS)

    Because flake-like TiAl3 particles in Al-Ti-C master alloys prepared in a melt reaction method dissolve slowly when they are added into Al melt at 720 deg. C, Ti atoms cannot be released rapidly to play the assistant role of grain refinement, leading to a poor refinement efficiency of Al-Ti-C master alloys. A united refinement technology by Al-10Ti and Al-Ti-C master alloys was put forward in this paper. The rational combination of fine blocky TiAl3 particles in Al-10Ti and TiC particles in Al-Ti-C can improve the nucleation rate of α-Al. It not only improves the grain refinement efficiency of Al-Ti-C master alloys, but also reduces the consumption

  19. Derivation of total filtration thickness for diagnostic x-ray source assembly

    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 Percutaneous nephrolithotomy (PCNL was introduced in 1976, and rapidly evolved into the gold standard for treatment of large and complex renal stones. The procedure continues to evolve with an emphasis on maintaining a high success rate of stone treatment while improving patient outcome with decreased morbidity. With the improvement of instrumentation and experience of PCNL, several modifications to the procedure have taken place in order to reduce the morbidity & early return to normal lifestyle. First described by Wickham et al., another technical variation of tubeless PCNL is totally tubeless approach. The aim of this study is to compare standard and totally tubeless PCNL with respect to safety and efficacy. MATERIALS AND METHODS This study was performed in the Department of Urology, RajaRajeswari Medical College and Hospital, Bangalore from June 2015 to March 2016 after ethics committee clearance. Forty patients planned for PCNL and who gave informed written consent were included in the study. Patients were divided into two groups, standard PCNL (with a nephrostomy tube and totally tubeless PCNL (no ureter stents or ureteric catheters. RESULTS Both the groups were similar in terms of patient and stone characteristics. The mean operation time was slightly longer in the standard group (106.74 minutes than in the totally tubeless group (100.32 minutes, but there was no statistically significant difference. There was no significant difference between the two groups with regard to serum creatinine change or blood loss. However, hospital stay and analgesia requirement was significantly less in the totally tubeless group. CONCLUSION Totally tubeless PCNL leads to shorter hospital stays and less postoperative pain. It can be used with a favourable outcome in selected patients (stone burden <2 cm, single tract access, no significant residual stones, minimal bleeding, and no requirement for a secondary procedure.

    @@ The effect of lateral oxidation on microstructures of the GaAs/AlAs/GaAs heterostructure was studied by x-ray specular reflectivity, nonspecular scattering and diffraction. The GaAs/Al2Oa/GaAs multilayer was obtained after oxidation of the GaAs/AlAs/GaAs sample. The results show that, before oxidation, there are two 40-Athick intermixing layers, one located between the AlAs sublayer and the GaAs substrate, and the other between the AlAs sublayer and the upper GaAs sublayer. After oxidation, these two intermixing sublayers disappear. The AlAs was oxidized into amorphous Al2O3 totally. The surface and interface roughnesses of the sample also decrease after oxidation.

    In the present study, rapidly solidified ribbons of Al87 Ni7Cu3 Nd3 metallic glass was prepared by usingmelt spinning. Devitrification process of the totally amorphous ribbons was investigated by high temperature X-raydiffraction analysis, combining with differential scanning calorimetry, under continuous and isothermal heating re-gime. The X-ray diffraction intensity and full width at the half maximum (FWHM) were analyzed to investigate theincrease of crystallized amount and growth of α-Al crystal particles. The results show that under continuous heatingregime, the metallic glass devitrifies via two main stages: primary crystallization, resulting in two-phase mixture ofα-Al plus residual amorphous phase, and secondary crystallization, corresponding to rapid precipitation of some in-ter-metallic phases in the form of dispersion or eutectic mixture. Under isothermal heating regime, only Al crystalprecipitates from the Al-rich amorphous matrix at low temperature, and when heating at 280 ℃ only Al crystal pre-cipitates within a short time, and then Al8 Cu4 Nd forms, followed by Al3 Ni, in the residual amorphous phase. Whenheating at higher temperature or for longer time, Aln Nd3 forms, the amorphous phase disappears, and the ribbonsdevelop into polycrystalline morphologies with multiply phase mixture of a-Al, Al8 Cu4 Nd, Al3 Ni, and Al11 Nd3.

    1994-12-01

    In the twelfth century the Arabic astronomer Ibn al-Kammâd, living in Islamic Spain, composed three sets of astronomical tables, called "zijes". The zijes were largely based on the work of predecessors, going back to Ptolemy on the one hand, and Hindu astronomers on the other. None of his zijes survived in the original Arabic, but a Latin manuscript contains a translation of an apparently complete zij, the "al-Zij al-Muqtabis". This paper examines the body of astronomical knowledge contained in this zij. Specifically, it is shown that one can gain valuable information on the solar theory of the Islamic astronomers from this translation. Furthermore, the theory of lunar and solar eclipses in the work is analyzed, and tables of mean planetary and solar motions are discussed. In addition, tables for the motion of the vernal equinox, star tables, and several topics of Islamic spherical astronomy are examined.

  9. Dynamic Modeling of ALS Systems

    Jones, Harry

    2002-01-01

    The purpose of dynamic modeling and simulation of Advanced Life Support (ALS) systems is to help design them. Static steady state systems analysis provides basic information and is necessary to guide dynamic modeling, but static analysis is not sufficient to design and compare systems. ALS systems must respond to external input variations and internal off-nominal behavior. Buffer sizing, resupply scheduling, failure response, and control system design are aspects of dynamic system design. We develop two dynamic mass flow models and use them in simulations to evaluate systems issues, optimize designs, and make system design trades. One model is of nitrogen leakage in the space station, the other is of a waste processor failure in a regenerative life support system. Most systems analyses are concerned with optimizing the cost/benefit of a system at its nominal steady-state operating point. ALS analysis must go beyond the static steady state to include dynamic system design. All life support systems exhibit behavior that varies over time. ALS systems must respond to equipment operating cycles, repair schedules, and occasional off-nominal behavior or malfunctions. Biological components, such as bioreactors, composters, and food plant growth chambers, usually have operating cycles or other complex time behavior. Buffer sizes, material stocks, and resupply rates determine dynamic system behavior and directly affect system mass and cost. Dynamic simulation is needed to avoid the extremes of costly over-design of buffers and material reserves or system failure due to insufficient buffers and lack of stored material.

    Full Text Available A associação do maior número de artroplastias totais de joelho com a maior expectativa de vida da população tem levado a mais complicações de longo prazo, que se somam à baixa qualidade óssea dos pacientes mais idosos e culminam, muitas vezes, em fraturas periprotéticas. Este complexo problema ortopédico tem apresentação clínica muito variável, podendo acometer quaisquer dos ossos do joelho e levar a resultados desastrosos, em virtude de sua difícil solução. O seu tratamento exige do ortopedista amplo conhecimento tanto de técnicas de artroplastia como de osteossíntese, além de elaborado arsenal terapêutico como, por exemplo, acesso a banco de ossos.The increasing number of total knee arthroplasties, in combination with the population's longer life expectancy, has led to a greater number of long-term complications. These complications are also correlated with poor bone quality in the elderly and often result in periprosthetic fractures. This complex orthopedic problem has very diverse clinical presentation, possibly afflicting periprosthetic fracture may happen in any bone that constitutes the knee and, due to the difficulty of finding a solution, may lead to disastrous outcomes. The treatment demands broad knowledge from the orthopedic surgeon, not only regarding arthroplasty techniques, but also osteosynthesis, as well as an elaborate therapeutic including, for example, access to a bone bank.

    Full Text Available In this study, the Al/Al2O3-SiC hybrid composite was produced by accumulative roll bonding (ARB. In the first and the second cycles, the particles were uniformly poured between the Al strips during each ARB cycle. In the subsequent cycles, ARB was repeated up to six cycles without adding the particles between the layers. After the total eight cycles, the particles were distributed uniformly without agglomeration in the Al matrix. The corrosion behavior of the hybrid composite was investigated and compared with that of the annealed and ARB processed Al. The corrosion tests were conducted by the potentiodynamic and electrochemical impedance spectroscopy tests in 3.5 wt-% NaCl solution. The anodic potential of the pure Al processed by ARB was more positive than that of the annealed Al while its corrosion current density was higher. The corrosion potential of the hybrid composite was somewhere between the annealed Al and ARB processed Al. The hybrid composite exhibited the lowest current density and the highest charge transfer resistance. The increased corrosion resistance of the hybrid composite was attributed to the inert character of the Al2O3 and SiC particles because these particles could decrease the active sites of the material surface and impeding the corrosive attacks.

    Electrical properties of InxAl1-xN/AlN/GaN structure are investigated by solving coupled Schr(o)dinger and Poisson equations self-consistently.The variations in internal polarizations in InxAl1-xN with indium contents are studied and the total polarization is zero when the indium content is 0.41.Our calculations show that the two-dimensional electron gas (2DEG) sheet density will decrease with increasing indium content.There is a critical thickness for AlN.The 2DEG sheet density will increase with InxAl1-xN thickness when the AlN thickness is less than the critical value.However,once the AlN thickness becomes greater than the critical value,the 2DEG sheet density will decrease with increasing barrier thickness.The critical value of AlN is 2.8 nm for the lattice-matched In0.18Al0.82N/AlN/GaN structure.Our calculations also show that the critical value decreases with increasing indium content.

    Los derechos humanos al agua y al saneamiento están íntimamente relacionados con otros derechos esenciales para la vida, como la alimentación o la salud. Su reconocimiento como derechos humanos en 2010 marca un hito importante en el respeto, protección y realización de estos derechos, que se encuentran seriamente vulnerados para una mayoría de población más vulnerable y empobrecida, sobre todo en el ámbito rural. Mucho camino queda aún para conseguir no sólo la disponibilidad de agua y saneam...

    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.

    The total energy loss of N+q ions (for v < Bohr velocity) grazing on the Al(111) has been simulated without any 'fit' parameter and compared with the experimental data. The energy loss due to the charge exchange, happening before the N+q hits the Al(111) surface, is studied. The present simulation shows that the energy loss strongly depends on the charge state of the projectile and the lattice orientation of Al(111) surface. The calculated total energy loss agrees with experimental data very well.

    Magnetoresistance and rectification are two fundamental physical properties of heterojunctions and respectively have wide applications in spintronics devices. Being different from the well known various magnetoresistance effects, here we report a brand new large magnetoresistance that can be regarded as rectification magnetoresistance: the application of a pure small sinusoidal alternating-current to the nonmagnetic Al/Ge Schottky heterojunctions can generate a significant direct-current voltage, and this rectification voltage strongly varies with the external magnetic field. We find that the rectification magnetoresistance in Al/Ge Schottky heterojunctions is as large as 250% at room temperature, which is greatly enhanced as compared with the conventional magnetoresistance of 70%. The findings of rectification magnetoresistance open the way to the new nonmagnetic Ge-based spintronics devices of large rectification magnetoresistance at ambient temperature under the alternating-current due to the simultaneous implementation of the rectification and magnetoresistance in the same devices.
