    Full Text Available En el año de 1945, Curd Davey y Rose eligieron la pirimidina como substancia de experimentación debido a que esta substancia se encuentra en las nucleo-proteinas y por su presencia en algunas sulfadrogas especial mente la sulfadiazina, de conocidas propiedades anti-palúdicas. Ensayaron la pirimidina y derivados en infestaciones por plasmodium gallinaceum en gallinas; y comprobaron que estas substancias tenían realmente acción antipalúdica. Pero al trasladar sus experiencias al hombre, encontraron que la pirimidina y sus derivados eran demasiado tóxicos. Pensando, entonces, en la similitud química del grupo de la pirimida y de la guanidina, incluyeron este último grupo en los compuestos para ensayar, descubriendo que la inclusión de la guanidina aumentaba grandemente la acción de las substancias en experiencia. Se obtuvo de esta manera un producto denominado en el numero 4-888, o paludrina, cuya fórmula o nombre químico es N. P. clorofenil N5 isopropildiguanidina, droga que se encontró muy activa contra las formas sanguíneas del Plasmodium Gallinaceum y que también se hallo activa contra las formas exoeritrocíticas del parásito. Esta capacidad de obrar sobre la fase exoeritrocítica es prácticamente exclusiva de esta substancia. Hasta hace poco tiempo esta fase exoeritrocítica, había sido demostrada solamente en trabajos de experimentación en las  aves; pero en la actualidad ha quedado también demostrada en la enfermedad humana, por experiencias del Filipino Nolasco and África, quien logro demostrar el plasmodium Vivax en el tejido retículo endotelial del pulmón de enfermos de paludismo, aunque ya Brug, en el año de 1940 había hecho comunicaciones en el mismo sentido. Se comprende la grande importancia de la paludrina, en el tratamiento del paludismo; si se considera que las recidivas de la enfermedad son debidas a la existencia de esta fase xeoeritrocítica.

  7. Breast. cancer. Prognosis factors - preliminar study

    International Nuclear Information System (INIS)

    Rotstein, S.; Fonseca, N.M.

    1984-01-01

    A preliminar study of prognosis factors in 8 cases of breast cancer is made. Are used as parameters the dimension, the localization and the nuclear differentiation degree (gN) of the primary tumor, the vascular invasion and the axillary histologic status (pN) and the sinus histiocytosis phenomenon. Among the studied factors, have special importance the presence of vascular invasion and the negative sinus histiocytosis (minimal or absent sinus histiocytosis). Both phenomena are considered as an expression of potential systemic disease, independent of the clinical stage. Consequently the use of chemotherapy in the surgery complementation is preconized, to a best control of the disease. (author)

    2016-07-01

    Full Text Available Resumen: Con el objetivo de alcanzar resultados satisfactorios en la enseñanza y puesta en práctica de cursos semestrales de ingeniería de control, en los que la presencia de alumnos de distintas disciplinas es más que notoria, se torna necesario recurrir a altos niveles de abstracción en la programación de los sistemas de control. Este alto nivel de abstracción procede del uso de un sistema de prototipado rápido para control de carácter avanzado, que permite recurrir a funcionalidades que no habían sido previstas en ningún entorno de prototipado rápido para control disponible con anterioridad. El carácter avanzado del sistema brinda soluciones desde el más alto nivel de abstracción, el denominado diseño basado en modelos, para las intricadas relaciones necesarias entre la ingeniería de control y la informática en tiempo real, permitiendo que los alumnos puedan centrar su esfuerzo en el desarrollo del algoritmo de control, la identificación de sistemas y el modelado de plantas físicas en lugar de preocuparse por las tediosas tareas de gestión y configuración a bajo nivel de la arquitectura hardware que están empleando. Gracias a este alto nivel de abstracción, que cubre el espectro abarcado por funcionalidades de muy bajo nivel y funcionalidades de muy alto nivel, el manejo del sistema propuesto se encuentra al alcance de audiencias multidisciplinares. El sistema avanzado de prototipado rápido para control se está empleando para cursos semestrales así como en multitud de Tesis de Máster y Doctorales. Abstract: In order to achieve successful results in the control courses for a multidisciplinary audience, a high abstraction layer at programming is required. This abstraction is provided by a custom developed rapid control prototyping system that enables the usage of model based design techniques to control real plants.

Es importante detectarlo en estadios tempranos, mediante endoscopia digestiva alta (EDA. Objetivos: Describir las características demográficas, clínicas y endoscópicas de una cohorte de pacientes en un hospital de tercer nivel de Bogotá con cáncer gástrico temprano (CGT o cáncer gástrico avanzado (CGA para establecer características que permitan definir enfoque clínico y endoscópico. Materiales y Métodos: Se recolectaron pacientes desde julio de 2005 hasta diciembre de 2013 para un total de 302; se valoraron reportes endoscópicos e historias clínicas. Las variables cualitativas se expresaron con proporciones y las cuantitativas con promedios. Se realizó un análisis de Ji cuadrado y pruebas paramétricas (T de student. Resultados: De 65 pacientes, el 50% es superior y menos del 5 % de los pacientes con cáncer gástrico se detectan en estado temprano. Los datos difieren de los reportado por Jap y colaboradores, quienes tuvieron el diagnóstico de CGT (edad promedio 63 años y 237 CGA (edad promedio 52 años. En nuestra cohorte, CGT fue más frecuente en mujeres 51% mientras CGA lo fue en hombres 63% y las lesiones tempranas fueron más comunes en pacientes con síntomas dispépticos (52%. En CGA se encontró con más frecuencia signos de alarma, pero no hubo diferencia en la localización de los tumores. La clasificación endoscópica de Paris para las lesiones tempranas fue: 23% I, 32% IIa, 6% IIb, 31% IIc y 8% III. Conclusiones: El CGT es más frecuente en mujeres y el promedio de edad es mayor, lo cual puede estar relacionado en que los pacientes con cáncer difuso son más jóvenes. Los síntomas de alarma son buenos indicadores para un diagnóstico temprano. La evaluación endoscópica debe hacerse de acuerdo al mejor método sistemático disponible en la institución.

    Full Text Available El objetivo de este trabajo consiste en el análisis de un conjunto esqueletal originariamente depositado en un ceramio con fines mortuorios. La vasija funeraria yacía superficialmente en adyacencias de un camino vecinal próximo a un antiguo afluente del río Dulce, en la región central de la provincia de Santiago del Estero. Toda el área inmediata a la zona del hallazgo conforma sitios de ocupación prehispánica, caracterizados por la presencia de cerámica Sunchituyoj. A pesar del estado sumamente fragmentario de la urna, y del deterioro parcial del contexto, se pudo rescatar todos los elementos óseos en ella depositados, los que corresponden a dos individuos, un adulto y un infante. Se aplicaron métodos convencionales, tanto escópicos como métricos, a fin de dilucidar la edad, sexo y estatura. El individuo adulto corresponde al sexo femenino y se estima en treinta años su edad a la muerte. Destaca en el mismo la presencia de osteofitosis en las vértebras y entesofitosis en los huesos largos. También se observa tejido óseo proliferativo en elementos costales y en el íleon. Asimismo puede evidenciarse caries e hipoplasia en el esmalte en algunas piezas dentales. Los componentes óseos del infante presentan un estado de conservación regular, estimándose en tres años su edad al deceso. A pesar de la destrucción parcial del contexto en el cual se encontraban los remanentes esqueletales en consideración, la información lograda a partir de los mismos es muy relevante, pues permite incrementar el conocimiento bioarqueológico para la región.

Houve queda acentuada da entrada de dados no período da descentralização, com aumento gradativo dos registros, à exceção de Pernambuco que apresenta um sub-registro importante. Os dados do SISPCE-DATASUS e IBGE são insuficientes para construção de indicadores para o monitoramento das formas graves da endemia e outros aspectos que possam relacionar as condições de saneamento com a ocorrência da doença. A reformulação do sistema de informações é fundamental para a efetivação das ações de controle diante da nova realidade do sistema de saúde. Esse deve ser repensado de forma a integrar-se às políticas de saúde em consonância com as diretrizes do SUS, utilizando metodologia de coleta de dados sistemática, adequada às especificidades locais, possibilitando comparações e avaliações prospectivas, além da construção de novos indicadores com ênfase na morbidade e nos determinantes da endemia e da adoção de unidades de análise que venham a expressar a real situação da esquistossomose nos Estados.This study provides a preliminary analysis of the Information System in the Schistosomiasis Control Program (SISPCE in the States of Bahia, Sergipe, Alagoas, and Pernambuco, Brazil, from 1999 to 2003.

  11. Funciones Fiscales, Procesos Presupuestarios y Modelos Constitucionales en Países Avanzados. El caso de Canadá

    Directory of Open Access Journals (Sweden)

    2007-04-01

    Full Text Available La política fiscal que se expresa en los presupuestos, refiere a recursos, gastos y endeudamiento.  En materia de presupuestos públicos, los fines fiscales no se alcanzan en tanto no exista una adecuada gestión de los mismos, y el proceso político-institucional del presupuesto sea compatible con el enfoque tripartito de presupuesto. Los principios económicos deberán articularse con principios administrativos y roles específicos de actores institucionales. En esa línea, son importantes tres requerimientos funcionales exigidos al presupuesto gubernamental desde la óptica administrativa: el de control, de gestión y de planeamiento. La primera función se alude al control del gasto público, para lo cual se asigna al presupuesto un papel esencial. Pero también importa su eficacia como instrumento de gestión o gerenciamiento de las variables de economía pública. Finalmente, es la herramienta donde por excelencia ha de estar contenido el plan de gobierno, incorporado a sus distintas operaciones, tal como se ha enfatizado, las opciones políticas contenidas en tales decisiones. Estas variables, pertenecientes a distintas visiones, no son neutrales a un eficaz proceso presupuestario, que implicará una relación entre la Rama Ejecutiva y el Parlamento, en los sistemas contemporáneos. Esa es la idea subyacente al considerar el caso de un modelo avanzado, como es el correspondiente a Canadá.

    Full Text Available Aunque en el territorio colombiano se han venido explotando los árboles caucheros del género Hevea durante casi medio siglo, solo ha sido en los últimos años cuando los botánicos han podido estudiar científicamente las especies en este país. En el presente artículo me limito a exponer de manera suscinta la identificación específica y la distribución geográfica del género Hevea en Colombia, valiéndome de las identificaciones botánicas preliminares que se han hecho hasta ahora, así como de los datos que he recogido personalmente y las informaciones que me han sido suministradas en fuentes fidedignas. Es de lamentarse la falta de exploración botánica en la hoya del río Inírida y sus afluentes que por ser, junto con el Guaviare, la región situada más al noreste de la zona de extensión del género Hevea, deja una laguna en los conocimientos que actualmente poseemos sobre la distribución geográfica de este género botánico. Igualmente carecemos de datos botánicos respecto de los ríos de menor importancia tales como el Yarí, el Cahuinarí y el Cotuhé, aunque sí los tenemos de las regiones mencionadas, lo mismo de otras vastas extensiones de la Amazonía Colombiana, podremos completar a satisfacción el estudio cuyo esbozo provisional presento en este trabajo.

Nel 2004, ormai più di cinque anni fa, è stato adottato, a maggioranza assoluta (solo due gli astenuti, il Preliminare di Piano Territoriale di Coordinamento della Provincia di Avellino, dopo un lavoro di oltre due anni che ha visto impegnati gli uffici provinciali con due dipartimenti universitari. Il lavoro, che va ben oltre il significato e la valenza di un preliminare e che coniuga due pratiche di piano diverse (quella tradizionale e quella strategica ruota attorno a tre idee di fondo, tra loro strettamente interrelate, che costituiscono i criteri guida che finora ha inteso seguire la provincia di Avellino nell’attività di governo delle trasformazioni. Tali idee, quindi, costituiscono le fondamenta su cui è stato costruito il Preliminare e sono la griglia di specificazione delle strategie e degli obiettivi di piano. Esse sono alla base delle scelte elaborate per lo sviluppo compatibile del territorio, e sono riferibili alle azioni operative di trasformazione del territorio che gli Enti locali, cui è demandato tale compito, nel prossimo futuro dovranno affrontare.

Además se diseñó un bloque en VHDL, el cual es el encargado de realizar la interfaz entre el microcontrolador y los periféricos de entrada- salida de la tarjeta. El ingreso de los datos a cifrar puede realizarse de dos maneras: mediante un teclado conectado al puerto PS/2 de la tarjeta o transmitiéndolos por el puerto serie de una computadora personal; para esto se diseñó una interfaz programada en Matlab¿. Los datos cifrados pueden observarse en el exhibidor LCD de la tarjeta de desarrollo, o bien se pueden transmitir en modo serial hacia una computadora personal. Estas opciones de funcionamiento del sistema se seleccionan mediante los interruptores deslizables de la tarjeta de desarrollo. La verificación del funcionamiento del sistema se realiza haciendo uso del documento oficial que describe a AES: FIPS-PUB 197. Aun cuando se implementó el algoritmo en un sistema basado en un procesador, se obtuvo un buen rendimiento. Se incluye la comparación del desempeño de nuestro diseño con otras arquitecturas que implementan también el mismo algoritmo.

Os entrevistados foram os ocupantes de cargos administrativos nas secretarias municipais da saúde pesquisadas. Conseguiu-se avaliar o uso das informações de custos na gestão de 18 secretarias municipais da saúde do estado de Santa Catarina. Os resultados indicam que apenas duas secretarias municipais da saúde possuem esse processo um pouco mais avançado; nas demais, o que se verifica é que existem algumas tentativas de se obter informações mais detalhadas sobre custos. Entretanto, na opinião dos entrevistados, as informações de custos são bastante importantes na gestão das secretarias.This article analyzes the use of costs information in decision-making by managers of the 20 local health departments in the state of Santa Catarina, Brazil.

Ese hecho despierta el interés para la realización de los estudios que propongan salidas para el diagnóstico preciso y el tratamiento eficiente de este síntoma en pacientes con cáncer avanzado.BACKGROUND AND OBJECTIVES: The importance of emotional symptoms in the context of the health-disease binomium, and efforts to spread information on Palliative Medicine motivated this article. The objective of this literature review was to propose a reflection on the diagnosis of depression in patients with advanced cancer with pain, based on existing concepts and definitions. CONTENTS: Pain and depression are prevalent symptoms in cancer patients. Considering the different points of intersection between physical and mental diseases, sometimes the diagnosis of depression in patients with cancer and pain is difficult. This datum is very important because depression decreases considerably the quality of life of patients, and should be diagnosed and treated properly. CONCLUSIONS: After reviewing the literature, a few questions remained unanswered. This fact awakens the interest to undertake studies that propose precise diagnostic solutions and efficient treatment of this symptom in patients with advanced cancer.

Para tanto, partiu-se da referência ao "chiste", efeito humorístico freudiano por excelência. A hipótese que aqui se desenha é a de que as vicissitudes econômicas relacionadas ao chiste, mesmo em seus estágios preliminares, podem esclarecer se e como tais intervenções podem ser efetivas num tratamento possível da psicose.The literal and the surprise: the preliminary stages of the wit. The target of this text is to explain in which way some humoristic interventions could help in the treatment of psychotic patients, pacifying the incidence of the "pulsional" and making the person, whose existence is not limited by the phallus, to start using speech. With this aim, our starting point was the mentioning of a "wit", or joke, the humoristic effect, which is Freudian by excellence. The hypothesis that we foresee is that the economic mishaps related to the wit, even on their preliminary stages, could clarify if and how such interventions could be effective in a possible treatment of psychosis.

Analisam-se as teorias freudianas da representação, do pensamento e da linguagem, com a finalidade de mostrar a coerência de seus conceitos com modelos que estão sendo debatidos atualmente nas ciências cognitivas. Correlacionando aspectos relevantes da teoria freudiana e alguns conceitos contemporâneos sobre o assunto, procura-se mostrar como os modelos atuais e o modelo freudiano concebem o pensamento como originário da experiência do sujeito, argumentando-se que não há dois processos de pensamento distintos mas diferentes padrões de conexão entre representações.Representation and thought in Freudian theory: introduction to a cognitive approach. This text presents some preliminary considerations for a cognitive approach to Freud's psychological theory of psychoanalysis. It analyses Freudian theories of representation, thinking, and language, in order to show that they are coherent with the cognitive models that are being discussed nowadays in the cognitive sciences. The text links some relevant aspects of the Freudian theory to contemporary concepts and shows how the models discussed and the Freudian models conceive the experiential origin of thought, arguing that there are not two distinct processes of thinking but different patterns of connections involving representations.

    Full Text Available El presente estudio se basa en el concepto de categorías corológicas o corotipos para formular una nueva hipótesis de clasificación biogeográfica del Perú basado en la distribución de la familia Astera - ceae. La información recabada dio como resultado que existen 1669 especies de Asteraceae registradas en Perú (hasta el año 2008, distribuidas en 255 géneros. El territorio peruano se dividió en 218 Distritos de Reporte que representan a los 24 departamentos divididos en franjas de 500 m de altitud. La base de datos biogeográficos de Asteraceae se obtuvo cruzando los registros de distribución actualizados con los Distritos de Reporte, expresándose en una matriz de presencia-ausencia. El análisis de datos dio como resultado un total de 14 corotipos preliminares para el Perú: Abiseo, Amotape, Andino, Apurímac-Huan - cavelica, Chachapoyas-Huánuco, Huancabamba, Huascarán, Ica, Lima-Piura, Loreto-Ucayali, Manu, Pasco, Sandia y Tacna.

    Full Text Available Objetivo. Evaluar procedimientos de manejo en cautiverio de ejemplares maduros de doncella Ageneiosus pardalis, con fines de reproducción y presentar una descripción preliminar del desarrollo embrionario y larvario para la especie. Materiales y métodos. Sobre ejemplares mantenidos en cautiverio se adelantaron dos ensayos de reproducción, así: a inducción con extracto de hipófisis de carpa EHC para la espermiación (4 mg/kg; una dosis intraperitoneal y para la ovulación (0.5 y 5 mg/kg; intraperitoneales, 0 y 12 horas; b inducción únicamente sobre hembras mantenidas en piletas, sin machos presentes, recolección y seguimiento de ovas. Resultados. Se comprobó la ovulación y la espermiación, pero no se avanzó en el desarrollo embrionario cuando se mezclaron los gametos y fueron incubados. Los ensayos con hembras inducidas, sin machos presentes, confirman el almacenamiento de esperma en los ovarios y los huevos obtenidos mostraron desarrollo embrionario completo, lográndose eclosión de larvas y el mantenimiento de alevinos. Conclusiones. El protocolo convencional de inducción fue efectivo en hembras y machos, pero la mezcla de los gametos no resultó ser un procedimiento viable para la producción de semilla en la especie. Se comprueba el almacenamiento de esperma en las hembras y la emisión espontánea de huevos fertilizados al medio cuando estas son sometidas a inducción. Tanto la forma y el tiempo de almacenamiento de esperma como los mecanismos fisiológicos que ocurren en la fecundación se desconocen.

    Full Text Available La presentación se corresponde con avances de un proyecto de investigación1 cuya finalidad principal está vinculada con el entendimiento de nuevas formas de organización de los espacios rurales patagónicos. Se ponen en discusión las posibilidades explicativas que sugieren, en su complejidad, distintas modalidades de tenencia de la tierra, tomando al ausentismo como característica analítica conducente. Metodológicamente concurren planteos de observación sistemática, con relevamientos bibliográficos y a campo, y la generación de referentes tipológicos. Los resultados preliminares muestran un espectro de situaciones diferenciadas en sus lógicas territoriales; así, el perfil económico rural (ganadería, minería, turismo, forestaciones, ahorro y/o especulación inmobiliaria se ve atravesado tanto por lógicas productivas como contemplativas. A todo esto, la organización de los espacios sobrelleva influencias cada vez más activas de varios procesos socio-culturales reivindicativos y/o conservacionistas. Se destaca asimismo el marco de discusión creciente de lo que se da en llamar ‘territorialidad virtual’, cuya asociación con el ausentismo, la sustitución dominial y los cambios en los usos del espacio resultan casi evidentes.La propuesta aspira a reflejar lineamientos básicos en la configuración espacial rural a favor de encontrar argumentos explicativos que permitan contribuir tanto con los enfoques multidisciplinarios que atañen al desenvolvimiento territorial en general, como con el Planeamiento regional.

    Full Text Available Abstract The perceived self-efficacy is considered as an important concept in many areas of the behavior, especially in teaching performance and stress. This research paper reports the preliminary psychometric findings based on the Perceived Self-Efficacy Scale (Tschannen-Moran & Woolfolk, 2001 in 313 elementary teachers and 352 high school teachers in Lima, Peru. The results concerning item analysis, reliability and internal structure support the psychometric integrity of this instrument in both samples. These results also suggest cross-cultural comparability of the constructs assessed. Given the importance of perceived self-efficacy and stress intervention amongst teachers, this instrument provides a reliable and structurally valid system for measuring these factors. Resumen La autoeficacia percibida es un concepto importante en muchas áreas del comportamiento, y muy especialmente en el desempeño docente y en el estrés. Justamente, el presente artículo de investigación reporta los hallazgos psicométricos preliminares de la aplicación de la Escala de Autoeficacia Percibida (Tschannen-Moran & Woolfolk, 2001 en 313 maestros de enseñanza elemental y 352 de secundaria en Lima, Perú. Los resultados concernientes al análisis de ítems, confiabilidad y estructura interna respaldan la integridad psicométrica de este instrumento en ambos grupos de participantes. Estos resultados también sugieren la comparabilidad intercultural de los constructos evaluados. Dada la relevancia de la eficacia percibida en la investigación y la intervención sobre el estrés docente, el instrumento permite una vía métrica que puede dar información confiable y estructuralmente válida.

    Full Text Available Puya raimondii Harms es una especie endémica de la zona altoandina de Perú y Bolivia, cuyas poblaciones y área de distribución se están reduciendo. Con el objetivo de contribuir al conocimiento de los mecanismos de propagación de la especie se realizaron estudios del efecto de la iluminación y estratificación en la germinación de sus semillas. Éstas se colectaron en el rodal de P. raimondii de Huashta Cruz (Pueblo Libre, Áncash en diciembre de 1999 y fueron almacenadas bajo condiciones de laboratorio en Lima, Perú, hasta el momento de los ensayos. Las semillas fueron desinfectadas con hipoclorito de sodio 2,6% y la germinación se realizó en placas petri con agua destilada estéril durante el año 2000. Los resultados preliminares muestran que las semillas de P. raimondii tienen altos valores de porcentaje e índice de velocidad de germinación al ser iluminadas. Efecto semejante tuvo estratificarlas por dos meses a 11 °C o incrementar el tiempo de almacenamiento hasta 8 meses pero resultó negativo aplicar los dos tratamientos a la vez. Se plantea que los altos contenidos de humedad de la semilla, temperatura de almacenamiento así como temperatura de germinación afectan negativamente los valores de germinación.

De estos, 11 están en mayor o menor actividad y 7 tienen historia de erupciones. Las capas geol6ógicas sobre las cuales se extiende el pals presentan zonas de elevada sismicidad

    Las caracterlsticas de la erupción del Nevado del Ruiz permiten clasificarlo como un volcan de tipo "'Pliniano- explosivo". que puede emitir enorme cantidad de gases y fragmentos sólidos a grandes velocidades y altas tempe­raturas, como tambien lodo caliente, con deshielo de las nieves perpetuas cuyo resultado es Ia formación del "lahar" que sepultó las poblaciones y cubrió extensas zonas de terreno. Estas erupciones se presentan de manera intermitente y su comportamiento es impredecible. Existe siempre la posibilidad de erupciones late­rales que aumentan su peligro y radio de acción.

Experimental design: we prospectively analyzed factors related to quality of life in a cohort of patients using the Nottingham Health Profile and the EORTC questionnaire (QLQ-CR 38. Patients: a total of 116 patients with locally advanced rectal cancer surgically treated in our hospital from 1994 to 1999. Results: quality of life scores for the various factors studied showed that quality of life was worse in women, in patients with tumors in the middle third of the rectum, and in patients undergoing low anterior resection. Conclusions: factors influencing quality of life in patients surgically treated for locally advanced rectal cancer included sex, tumor site, and surgical technique. Since only this latter factor is modifiable, we suggest that the surgical technique be individualized in persons with mid-lower and lower-third tumors of the rectum, bearing in mind that quality of life in amputated patients is, in many respects, better than that of patients with preserved sphincters.Objetivos: debido al creciente interés por el bienestar tanto físico como psicológico y social de los pacientes intervenidos por Cáncer de recto, hemos diseñado un estudio para evaluar los factores que determinan la calidad de vida en estos pacientes.

They require codes and specifications, what makes that an entity should lead the use of the new material or technology. At present, the experience needed to prepare those codes does not exist. Experimental tests and successful cases are necessary for the acceptance of these materials in construction. In this work, an introduction to the subject is done and notice is given of a project which is developing with the aim to provide the experimental basis, needed to update design codes and standards, and the technology for the use of these new composites in building and civil structures strengthening, taking actual pathology, quality and durability into account, as well as urban aesthetics. Research specialists in composites, structural analysis and testing, and in structural pathology, as well as composites and adhesives manufacturers and appliers, designers and final users will cooperate in this project. This will allow that all relevant aspects of the problem be considered.

    La restauración, refuerzo o rehabilitación de estructuras resulta ser uno de los campos de aplicación de mayor interés y más directamente relacionado con los nuevos materiales compuestos. La Industria de la Construcción no ha aceptado aún el uso estructural extenso de los nuevos materiales compuestos, porque todavía no conoce bien cuándo existen ventajas respecto a los materiales tradicionales, tales como el hormigón o el acero. Los profesionales implicados en el proyecto y en la ejecución de obras suelen ser conservadores y resistirse a los cambios. Para aceptar un nuevo material requieren disponer de normativa relativa a la nueva tecnología, lo que hace necesario que alguna entidad lidere la aceptación del nuevo material o tecnología. Actualmente no existe ni a nivel nacional ni internacional la experiencia precisa para el desarrollo de tal normativa. Para ello es necesario tener la adecuada base experimental y de realizaciones con éxito. En el presente trabajo se trata de hacer una introducción al tema y de dar noticia de un proyecto de investigación que se está desarrollando, orientado a proporcionar la base experimental requerida para poner a punto, en un próximo futuro, normas y recomendaciones para el proyecto y la tecnología para el uso de estos nuevos materiales compuestos en el refuerzo de estructuras de edificación y obra civil, atendiendo a su patología, calidad y durabilidad del refuerzo, y a la estética urbanística. En él colaboran especialistas en investigación en materiales compuestos y en análisis teórico y experimental y en patología de estructuras, fabricantes y aplicadores del material y adhesivos, proyectistas y usuarios finales, lo que permitirá considerar todos los aspectos del problema.

    Full Text Available La actividad que se estudia es un proceso para inertizar el mercurio de las luminarias (desechos de bombillos y fluorescentes. Este consiste en triturar y mezclar los desechos con azufre aplicando calentamiento para formar un polímero de sulfuro de mercurio, que resulta un producto sólido, inerte, estable y de baja lixiviación que se puede depositar en un relleno sanitario. El calentamiento causa la generación de vapores de azufre molestos y de olor desagradable, por lo que se realizó un cambio del método de tratamiento sin calentar, mediante el uso de una mezcla del desecho de luminaria con azufre y mortero (cemento y arena. Las pruebas de laboratorio preliminares presentan resultados positivos para efectuar pruebas a nivel de planta piloto con este nuevo método a temperatura ambiente. Este proyecto se desarrolló en una de las actividades productivas del Centro de Investigación en Protección Ambiental (CIPA del Tecnológico de Costa Rica.

Steinberg que se administró a una muestra de 224 adolescentes entre 11 y 19 años de un colegio público en Lima. Mediante el análisis factorial confirmatorio de grupo múltiple, la estructura de tres subescalas (Compromiso, Autonomía Psicológica y Control Conductual/Supervisión se mantuvo en general estable, aunque la agrupación teórica de los ítems tendió a estar influenciada por la distribución de los ítems. La confiabilidad alfa para las subescalas solo alcanzó niveles marginales de aceptación y se reconoció el probable impacto del error de medición aleatorio. Los resultados muestran que el instrumento utilizado es una herramienta potencial para la investigación, pero estos hallazgos son preliminares y se requieren estudios adicionales para evaluar la generalización del análisis efectuado.

Los cáculos se hicieron con el método basado en la pérdida de componentes en solución utilizando diferentes valores de solutos. Al utilizar la pérdida de sílice se obtiene un tiempo de meteorización de unos 6 x 10 6 años, comparable con el obtenido mediante la datación de las cenizas volcánicas mas antiguas que recubren la topografía actual y que indican la fecha mínima de configuración de la superficie de erosión.A pesar de resultar de una serie de suposiciones simplificadoras, este resultado es interesante y justifica la realización de determinaciones mas detalladas. Confirma la larga preservación de superficies de erosión antiguas conformadas sobre un saprolito que desde hace varios millones de años no ha sido sometido a una erosión profunda, fenómeno poco común en una zona tectónicamente activa como la estudiada.

    Full Text Available Introdução: Alterações nos ritmos circadianos tem sido frequentemente observadas entre pacientes com Transtorno do Humor Bipolar (THB. No entanto, existem poucos instrumentos para medi-las e a maioria deles mede exclusivamente distúrbios do sono. A escala BRIAN, validada para adultos com THB, avalia a regularidade dos ritmos biológicos em quatro diferentes aspectos: sono, atividades, social e padrão de alimentação. O objetivo deste estudo piloto foi adaptar a escala BRIAN para uma população de crianças e adolescentes (BRIAN-K e avaliar se o novo instrumento é capaz de detectar diferenças entre pacientes e controles saudáveis. Métodos: Foram avaliados 20 pacientes com THB entre 8-16 anos e 32 controles pareados por sexo e idade. Os sujeitos foram avaliados através de entrevista clínica, K-SADS-PL e testagem cognitiva. A BRIAN-K foi aplicada em ambos os grupos. Resultados: O grupo de pacientes com THB apresentou escores mais altos de alterações em seus ritmos circadianos pelo escore total da BRIAN-K, quando comparados com o grupo controle (p=0,022. Particularmente, maior irregularidade foi observada no domínio “atividades” no grupo de pacientes (p=0,001. Nossos resultados também mostraram uma correlação positiva entre a idade de diagnóstico e o domínio “sono” da BRIAN-K (r = 0,485; p = 0,03. Conclusões: Estes dados preliminares sugerem que a versão BRIAN-K, recentemente adaptada para crianças e adolescentes, é capaz de discriminar pacientes com THB e controles. Futuros estudos com maior tamanho amostral são necessários para determinar a confiabilidade, validade interna e externa do presente instrumento.

    The aim of this analysis was to obtain information regarding the mtDNA haplotype composition of the manatee (T. manatus) occupying the Cuban archipelago. A fragment of 410 bp of the non-coding region was analyzed for 12 individual manatees from Cuba and one from Florida, USA. Only two haplotypes were identified. Haplotype A1, found exclusively in Florida (including in the sample analyzed here) but also found in Mexico, the Dominican Republic and Puerto Rico, was the most frequent haplotype (11 of the 12 samples from Cuba) and widely distributed. The second haplotype A3, previously referred to as endemic from Belize, was identified from an individual stranded in Isabela de Sagua, north of Cuba. These preliminary results provide information about three major aspects of manatee biology: (1) the mtDNA genetic diversity of T. manatus in Cuba seems low as compared to other regions of the Caribbean; (2) the Cuban population likely belongs to the group comprising Florida and the portions of the Greater Antilles; and (3) the territories of Belize and Cuba have exchanged individuals at present or in a relatively recent past.

RESULTS: Enhanced SPGR detected eight cystic lesions, with scolices in four. Contrast enhancement was observed in three cysts. FIESTA also detected eight cystic lesions with the presence of scolices in seven of those cystic lesions. Four patients presented parenchymal involvement, while the remaining three presented the racemose form. CONCLUSION: FIESTA and SPGR are sequences that can detect intraventricular cysts of neurocysticercosis, and FIESTA also is good for the detection of the scolex. Considering this information we suggest that FIESTA and SPGR should be included in the MRI protocol for the investigation of intraventricular neurocysticercosis.

    tratamento.PURPOSE: to compare the information obtained with pelvic and transvaginal ultrasonography (USG, hystero-salpingography (HSG, diagnostic hysteroscopy (HSC, pelvic nuclear magnetic resonance imaging (PNMR, three-dimensional hysterosonography (3D HSSNG, to optimize and simplify the investigation about cervical and corporeal uterine factors in conjugal infertility. METHODS: in the period between January and July 2003, fifty women reporting infertility for at least two years were submitted to USG, HSG, HSC, PNMR, and 3D HSSNG as tracking examinations for uterine factor diagnosis. The endocervical canal, as well as the endometrium, myometrium, and the presence of uterine malformations were investigated. The results of each examination were analyzed and compared. RESULTS: of the 50 women studied, 12 (24% presented alteration in at least one of the examinations. When 3D HSSNG was compared to USG, 3D HSSNG provided additional information in 7 cases (58.3%; when compared to HSG, it provided additional information in 7 cases (58.3%; when compared to HSC, it provided additional information in 4 cases (32.1%, and when compared to PNMR, it provided additional information in 6 cases (50%. There were only two cases in which HSG detected alterations of the endocervical canal that were not visualized using 3D HSSNG. In the other cases 3D HSSNG imparted the same diagnosis; furthermore, it provided additional information in comparison to the other examinations. Statistical analysis using the kappa test demonstrated that the diagnoses obtained by 3D HSSNG were in agreement with those obtained with USG, HSG and PNMR (p<0,05. When the HSG and 3D HSSNG results were combined, all conditions associated with infertility could be precisely diagnosed, using only these examinations. CONCLUSION: the association of the HSG with 3D HSSNG may be sufficient for the diagnosis of cervical and corporeal uterine factors in infertility, reducing the number of examinations for each patient, the total

    2001-07-01

    constituye un grave problema a nivel nacional. En este trabajo se realiza una caracterizacion preliminar de la descarga liquida del Hospital Mexico. Para ello se analizaron diferentes puntos de vertido dentro de la institucion, ellos son : Lavanderia, cocina central, Laboratorio Clinico, Rayos X, Laboratorio de Biomasa, Morgue y la descarga final del hospital. Esto con el fin de conocer el manejo de los desechos liquidos en el centro de salud, la calidad sanitaria de estos vertidos y su influencia en las aguas crudas del Hospital Mexico en el cuerpo receptor. Para este estudio primero se coordino con el personal de cada departamento para conocer sobre el manejo y tipo de residuos liquidos que son descargados al sistema de tuberias. Posteriormente se realizaron las pruebas fisico-quimicas y biologicas con base en dos muestreos compuestos realizados los dias 26 de octubre y 4 de noviembre de 1998. Entre las pruebas realizadas se tienen: pH, DBO, DQO, SAAM, Grasas y Aceites, Temperatura, Nitrogeno y Coliformes Fecales, dependiendo de las caracteristicas de su punto de procedencia. Al final del estudio, se evaluaron los resultados obtenidos para cada punto de vertido estudiado y luego se analizo la influencia de estos focos sobre la calidad de las aguas crudas del hospital, las cuales descargan en una quebrada localizada al costado noroeste de las instalaciones. Los resultados obtenidos permiten conocer preliminarmente la caracterizacion de la descarga liquida del Hospital Mexico y lo catalogan como una fuente de contaminacion. El Hospital requiere de una planta de tratamiento biologica para aquellos vertidos biodegradables, y de un sistema de tratamiento quimico para tratar ese tipo de productos, que son utilizados en los procesos propios de cada departamento; ademas se requiere tomar en cuenta medidas de reduccion de contaminacion que disminuyan la cantidad de desechos desde la fuente.

Existió un predominio del sexo femenino y edad media de 44,6 años. La intubación prolongada de origen diverso fue la causa de la estenosis en 4 de los 5 pacientes y en 1 fue posterior a la reparación de lesión traqueal yatrógena. La instalación de la estenosis tuvo lugar entre 8 días y 3 meses. La tomografía lineal en 3 pacientes y en 2 la radiografía simple de tráquea anteroposterior y lateral verificaron el diagnóstico. La endoscopia traqueobronquial preoperatoria fue de utilidad en la caracterización de la estenosis. En todos los pacientes se realizó tratamiento quirúrgico al resecar el área estenótica con posterior anastomosis terminoterminal y fijación del cuello en flexión durante 8 días como promedio. Dos pacientes mostraron granulomas en el nivel de la línea de sutura, los cuales fueron tratados por vacuolización con láser. No se reportó mortalidad en la muestra estudiadaA retrospective and descriptive study was conducted by using the medical histories of 5 patients with tracheal stenosis, mostly as a result of prolongued intubation. Aspects connected with the diagnosis, treatment and complications were taken into account. It was observed a predominance of females and an average age of 44.6. Prolongued intubation of different origin was the cause of stenosis in 4 of the 5 patients, whereas in the other it occurred after the reparation of the tracheal and athrogenous lesion. The installation of stenosis took place between 8 days and 3 months. Lineal tomography in 3 patients and anteroposterior and lateral simple X-ray of the trachea in 2 confirmed the diagnosis. Preoperative tracheobronchial endoscopy was useful to characterize stenosis. All patients underwent surgical treatment with resection of the stenotic area by posterior terminoterminal anastomosis and fixation of the neck in flexion during 8 days as an average. 2 patients that had granulomas at the level of the suture line were treated with nuclear vacuolization. No mortality was reported in the studied sample

Se coletivamente apostamos na dimensão de território como agenciamento, como conceito que se organiza na indissociabilidade espaço-tempo e que dá visibilidade à dinâmica social em torno de qualquer produção identitária (HAESBAERT, 2014, suspeito que, por ora, a concepção restrita do território como objeto silencia as camadas do conflito.

    Full Text Available Apresenta-se uma lista preliminar das espécies de Lutzomyia conhecidas para o Estado do Maranhão. As informações apresentadas derivam de dados relatados na escassa literatura sobre o padrão de distribuição dos flebotomíneos neotropicais. Até o momento, quarenta espécies já foram registradas para o Estado. A maioria é típica da fauna amazônica, as demais ou são características das savanas do Brasil Central ou têm ampla distribuição neotropical. As razões dessa superposição devem-se à localização do Maranhão em uma área de transição entre as macrorregiões que caracterizam o Norte, o Nordeste e o Centro-Sul do Brasil. Entre as espécies lá encontradas, sete são conhecidas como vetores de agentes etiológicos das leishmanioses americanas.

    Full Text Available Con el fin de determinar si el agua recolectada artificialmente de la niebla en la zona central montañosa del Estado de Veracruz es apta para el consumo humano, se realizó un muestreo preliminar de enero a marzo del año 2010, periodo de mayor frecuencia de nieblas, para analizar sus aspectos físicos, químicos y biológicos y evaluar su calidad. Se encontró que el agua contiene metales pesados como el mercurio, organismos coliformes y cantidades altas de nitrógeno amoniacal, pero esto se puede solucionar aplicando un tratamiento de saneamiento para uso humano con un costo de 0.00341 USD L -1 que no incluye mano de obra ni infraestructura. Se discuten las causas que pueden originar su contaminación y se concluye que el agua recolectada de la niebla no es adecuada para el consumo humano, pero sí para la agricultura.

    In 4{pi} {beta}-{gamma} coincidence measurements, precision on the evaluation of coincidence counting losses is made difficult because of complex overlapping effects between the{beta}--and {gamma}-side dead times due to pre cursive counted events. In this context the SAMAR electronic system is aimed to give a precise way of automatic counting and reduce the need for calculated corrections. This report describes its configuration and basic features. The SAMAR has been conceived in such a manner that both beta and gamma chains are sharing a common and non extending dead-time which is simultaneously applied to both channels. The shared dead time is made to be the only one inserted throughout the chains. Overlapping effects vanish and the three counting channels have identical transmission ratios. A new dead-time circuit based on fast linear gates as blocking elements has been developed. Application of the two-oscillator Muller's method evidences a fully non-extending character. Automatism is implemented by using a live timer corrective channel controlling the counting scalers. (Author) 21 refs.

    Full Text Available Los modelos actuales sobre el trastorno obsesivo-compulsivo prestan una especial atención a las creencias y valoraciones para explicar la etiología y el mantenimiento del mismo. Para poner a prueba estos modelos es necesario desarrollar instrumentos de evaluación que sean fiables. En el presente estudio instrumental de corte transversal se presenta un cuestionario específicamente diseñado para evaluar estas creencias en muestras españolas, así como los datos preliminares sobre su fiabilidad y validez. El cuestionario de 58 ítems fue completado junto con el Cuestionario Maudsley de Obsesión-Compulsión (MOCI por 253 sujetos normales (79 hombres y 174 mujeres; edad media=27,8 ±11,12 años. El análisis factorial reveló la existencia de siete dimensiones en las que se agrupaban las creencias: Fusión pensamiento-acción tipo probabilidad, Perfeccionismo e intolerancia a la incertidumbre, Sobrestimación del peligro, Fusión pensamiento-acción tipo moral, Responsabilidad excesiva e importancia de controlar los pensamientos, Sobrestimación de la importancia de los propios pensamientos y Rigidez de ideas. Estos factores fueron idénticos en ambos sexos, que además no difirieron en las puntuaciones medias alcanzadas en cada uno de ellos. Los indicadores de consistencia interna y repetibilidad fueron excelentes. El inventario correlacionó significativamente con el MOCI y la dimensión de sobrestimación del peligro fue la que mejor predijo la puntuación en este último cuestionario.

La distribución y el almacenamiento del agua después de su potabilización, pueden originar cambios significativos en su calidad, por lo que es necesario conocer las características finales del agua domiciliaria que consumen los usuarios. Objetivo. Evaluar de forma preliminar las sustancias químicas tóxicas en el agua de tanques y grifos de viviendas abastecidas por el acueducto de Bogotá. Materiales y métodos. Se hizo un estudio descriptivo en 26 viviendas localizadas en Bogotá y Soacha. Se hicieron dos muestreos: uno en época de lluvias y otro en temporada seca, y en ambos se aplicó una encuesta y se recolectaron muestras de agua de los tanques de almacenamiento y los grifos. Las muestras se sometieron a ensayos fisicoquímicos básicos, a una prueba de tamización de sustancias orgánicas e inorgánicas, y a pruebas de determinación de metales pesados y de residuos de plaguicidas organofosforados y carbamatos. Resultados. La conductividad, el color y los nitratos presentaron valores permisibles; el pH y la turbiedad tuvieron una ligera tendencia a presentar niveles altos y, el cloro residual, niveles bajos. Hubo trazas de aluminio en el 94 % de las muestras. En el período seco, 8 % de las muestras presentó compuestos orgánicos y, en el período lluvioso, 66,7 %. Solo hubo un resultado positivo para las sustancias inorgánicas. En el 11,5 % de las viviendas, el nivel de riesgo fue medio, en el 61,5 %, bajo, y en el 27 % no se registró riesgo. Conclusiones. Se evidenció deterioro de la calidad del agua domiciliaria debido a la presencia de sustancias orgánicas en tanques y sobre todo en las redes, presumiblemente a causa de la formación de biopelículas o a la presencia de polímeros orgánicos. Los niveles de aluminio cercanos al máximo aceptable pueden explicarse por los remanentes de los coagulantes utilizados durante el tratamiento.

    Full Text Available Este trabajo presenta algunas preguntas y desarrollos preliminares surgidos en un recorrido teórico realizado por los textos freudianos del término "aptitud". - Se presentan las referencias a textos anteriores a 1920, aunque se privilegie, en función de los objetivos de la investigación en curso, el ordenamiento y relación de la "aptitud de analista" con los conceptos fundamentales de la segunda tópica freudiana. ¿Se puede elevar el término castellano aptitud y sus originales alemanes al estatuto de un concepto? Finalmente se planteará que la dimensión pulsional del término es lo que permite darle a la "aptitud de analista" un estatuto conceptual, ya que la aptitud como "tauglich" en el advenimiento de un nuevo analista implica una transmutación pulsional específica. La pregunta por cuál es la relación entre lo que porta el carácter y la recomposición de las alteraciones del yo en el período posterior al análisis quedará como orientación para otro trabajo.This work presents some questions and preliminary developments which erased during the theoretical examinations realized on the Freud's texts concerning the term ¨competence¨. The references to the texts earlier than 1920 are given, however, in function of the objectives of the investigation in course, the order and relation of the ¨analyst' s competence¨ to the fundamental concepts of Freud's second topography are favored. Can we give a Spanish term ¨aptitud¨ and its German originals a status of a concept? Final consideration will be that the instinctual dimension of the term is what permits to give it a conceptual status to the ¨analyst's competence¨, since ¨competence¨ as ¨tauglich¨ in making a new analyst implies a specific instinctual transmutation. The question about what is the relation between what makes a character and the reparation of the alteration of ¨I ¨ in the period following the analysis will remain an orientation for further work.

    In a Solar Central Internal Film Receiver, the heat absorbing fluid (a molten nitrate salt) flows in a thin film down over the non illuminated side of an absorber panel. Since the molten salt working fluid is not contained in complicated tube manifolds, the receiver design is simples than a conventional tube type-receiver resulting in a lower cost and a more reliable receiver. The Internal Film Receiver can be considered as an alternative to the Direct Absorption Receiver, in the event that the current problems of the last one can not be solved. It also describes here the test facility which will be used for its solar test, and the test plans foreseen. (Author) 17 refs.

  6. Automatic segmentation and 3D reconstruction of intravascular ultrasound images for a fast preliminar evaluation of vessel pathologies.

    Intravascular ultrasound (IVUS) imaging is used along with X-ray coronary angiography to detect vessel pathologies. Manual analysis of IVUS images is slow and time-consuming and it is not feasible for clinical purposes. A semi-automated method is proposed to generate 3D reconstructions from IVUS video sequences, so that a fast diagnose can be easily done, quantifying plaque length and severity as well as plaque volume of the vessels under study. The methodology described in this work has four steps: a pre-processing of IVUS images, a segmentation of media-adventitia contour, a detection of intima and plaque and a 3D reconstruction of the vessel. Preprocessing is intended to remove noise from the images without blurring the edges. Segmentation of media-adventitia contour is achieved using active contours (snakes). In particular, we use the gradient vector flow (GVF) as external force for the snakes. The detection of lumen border is obtained taking into account gray-level information of the inner part of the previously detected contours. A knowledge-based approach is used to determine which level of gray corresponds statistically to the different regions of interest: intima, plaque and lumen. The catheter region is automatically discarded. An estimate of plaque type is also given. Finally, 3D reconstruction of all detected regions is made. The suitability of this methodology has been verified for the analysis and visualization of plaque length, stenosis severity, automatic detection of the most problematic regions, calculus of plaque volumes and a preliminary estimation of plaque type obtaining for automatic measures of lumen and vessel area an average error smaller than 1mm(2) (equivalent aproximately to 10% of the average measure), for calculus of plaque and lumen volume errors smaller than 0.5mm(3) (equivalent approximately to 20% of the average measure) and for plaque type estimates a mismatch of less than 8% in the analysed frames.

The methodology of factorial 2k designs was followed, which included a comparison between pressing and n-hexane extraction methods. The regression model corresponding to the comparison between ethanol and n-hexane, varying extraction time, did not have lack of fit and presented an R2 of 99%. The experimental design for the pressing method, varying press rotation speed and temperature, yielded a poorly fitted linear model. The oil composition extracted with ethanol was similar to those obtained by n-hexane and by pressing. The highest yield (36.7% was obtained using ethanol for 4 hours. The excess of extracted material was attributed to additional solubilization of impurities that could be diminished by limiting the extraction time to 1 hour. The oil extracted with ethanol and by pressing have the same color. It is presumed that the purification steps for both oils should be similar. Further studies using mixtures of ethanol with small proportions of n-hexane are suggested.Fue realizada una evaluación preliminar de la extracción con etanol anhidro, del aceite de semillas enteras de Jatropha curcas L.

    Full Text Available In this project we are developing an instrument for measuring the wave-front aberrations of the human eye using the Hartmann-Shack sensor. A laser source is directed towards the eye and its diffuse reflection at the retina generates an approximately spherical wave-front inside the eye. This wave-front travels through the different components of the eye (vitreous humor, lens, aqueous humor, and cornea and then leaves the eye carrying information about the aberrations caused by these components. Outside the eye there is an optical system composed of an array of microlenses and a CCD camera. The wave-front hits the microlens array and forms a pattern of spots at the CCD plane. Image processing algorithms detect the center of mass of each spot and this information is used to calculate the exact wave-front surface using least squares approximation by Zernike polynomials. We describe here the details of the first phase of this project, i. e., the construction of the first generation of prototype instruments and preliminary results for an artificial eye calibrated with different ametropias, i. e., myopia, hyperopia and astigmatism.Neste projeto estamos desenvolvendo instrumento para medidas das aberrações de frente de onda do olho humano usando um sensor Hartmann-Shack.

Such investigations should consider other mining operations beyond the scope of this study as well as the kinetics of the acid generation by simulated weathering procedures.A despeito da importância econômica de atividades mineralógicas para o estado de Minas Gerais, perceber-se que elas causam significativo impacto ao ambiente. Drenagem ácida é um dos aspectos ambientais considerados pela atividade em função de seus impactos. Ela tem origem a partir da oxidação de sulfetos metálicos que acidificam as águas, com possibilidade de mobilizar elementos tóxicos e poluir os recursos hídricos. Este trabalho teve como objetivo realizar uma avaliação preliminar do problema em Minas Gerais. O trabalho teve início a partir de um levantamento bibliográfico junto a Fundação Estadual de Meio Ambiente (FEAM para identificar minerações cujo minério está associado a sulfetos. Amostras dos substratos foram retiradas para determinar o potencial de acidez (AP e de neutralização (NP. AP foi avaliado por dois procedimentos: pelo teor total de sulfetos e pela oxidação com peróxido seguida da titulação ácida. O NP foi avaliado pelo teor equivalente de carbonato de cálcio. Lâminas petrográficas foram preparadas para a descrição mineralógica com ênfase em sulfetos e carbonatos. O balanço ácido-base (ABA foi determinado pela diferença entre AP e NP, enquanto o potencial de geração de águas ácidas foi obtido pelo valor de ABA e o volume total de material de cada atividade minerária. Os resultados permitiram identificar quatro substratos com potencial para gerar drenagem ácida no estado de Minas Gerais. Juntas, estes materiais representam um potencial de geração de cerca 3,14 a 10,37 bilhões de metros cúbicos de água a pH 2,0 ou 31,4 a 103,7 bilhões de metros cúbicos de água a pH 3,0. Estes valores significam custos entre US$ 7,8 e 25,9 milhões para neutralizar a acidez com o uso de calcário. Estas estimativas são provavelmente

    Petrographic studies of cuttings from the shallow well Ixtlan 2, drilled in the Ixtlan de los Hervores geothermal zone, State of Michoacan, Mexico, at a maximum depth of 159 meters, together with results of previous exploration studies, allow to delineate a preliminary conceptual model of the probable geothermal system. It is formed by a wide-fracture zone system, with low topographic relief and shallow water level. Its hydrothermal fluids are of sodium-chloride type, neutral pH, silica oversaturated in the discharge and with temperatures between 125 and 225 degrees Celsius, based on the geothermometry and the hydrothermal mineral assemblage encountered in the well. The assemblage of laumontite + quartz + calcite + chlorite/smectite + pyrite is typical for the zeolitic facies, beneath of which it is possible to encounter the epidote-wairakite facies, with higher temperatures. The favorable conditions of the zone allow to recommend continuation of exploration in the same.

At these areas the network capacity could be a limit to exploitation of wind resource.There are two main problems related with the associated power of wind resurge and the network weak. First, it is related with steady state voltage level: when demand is low the voltage level could increase more than permitted limits if the energy production is high. The second problem is related with flicker voltage: the wind resource is not constant and the disconnection of the wind turbines could cause flicker voltage more than permitted limits.In Cuban electric system the presence of weak network is normally and different problems like hurricanes or work this electric system require to divide on electric subsystems with possible high contribution of wind generation. The preliminary analysis at one zone of Cuban´s archipelago from the point of view of wind penetration is presented in this paper.

    Full Text Available OBJETIVO: Embora o uso de cocaína seja um problema significativo de saúde pública, há uma relativa escassez de dados científicos sobre as conseqüências neurocognitivas decorrentes da exposição à substância. MÉTODOS: Esse estudo avaliou a associação entre dependência de cocaína e crack e desempenho cognitivo. Uma ampla bateria de testes neuropsicológicos foi aplicada a 15 dependentes de cocaína, em abstinência por duas semanas, em tratamento em regime de internação, e em 15 sujeitos controles, não usuários de drogas, pareados por idade, sexo, escolaridade, nível sócio-econômico, lateralidade e QI. RESULTADOS: Os resultados preliminares mostraram significação estatística (pOBJECTIVE: Although cocaine use is a significant public health problem, there is relative paucity of scientific data on long-term neurocognitive consequences of the exposure to the substance. METHODS: This study examined the association between crack cocaine dependence and neuropsychological performance. An extended battery of neuropsychological tests was administered to 15 abstinent cocaine abusers, inpatients in abstinence for two weeks, and 15 non-drug-using control subjects matched for age, gender, education, socio-economic status, handedness and IQ. RESULTS: The preliminary findings showed statistical significance (p<0,05 on differences of performance in attention, verbal fluency, verbal memory, visual memory, learning ability and executive functions. CONCLUSIONS: These results represent evidences that cocaine abuse is associated with decrements in cognitive functioning, similar to cognitive disorders associated to prefrontal and temporal brain impairments. Knowledge of specific cognitive deficits in cocaine abusers may be useful for designing more effective substance abuse prevention and treatment programs.

    Constitutional delayed growth (CDG is defined as that condition in which height is below the third percentile in Tanner Whitehouse growth curves, associated to a similar delay in skeletal maturity (Greulich and Pyle Atlas, and to the absence of deficiencies of Growth and Thyroid hormones or of nutritional and psychosocial conditions. The subjects of this study were 15 boys and 6 girls (age 13.4 :t: 3.1 years, range 10.9-16. Thirteen boys and 1 girl were at a prepuberal stage of development at the beginning of the study. In order to check the spontaneous growth velocity (GV, the patients were followed for a four-month period before starting any treatment. The boys under 13 years and all the girls received clonidine during a 4-12 month period (0.1 mg/m2/day. With this drug the boys Increased their GV from 5.9 :t 3.12 cm/year to 7.04 :t 2.23 cm/year (NS, and the girls from 5.53 :t 2.31 to 6.45 :t 1.18 cm/year (NS. However, two subgroups were clearly differentiated: the children who had some response to clonidine and those who did not. In the boys that responded, the spontaneous GV before clonidine was significantly less than that of those who did not respond (3.8 :t 3.27 vs 7.67 :t 1.66 cm/year (P< 0.05. The figures for the girls were 3.5 :t 0.86 and 7.57 :t 0.4 cm/year, respectively (P< 0.01 . Nine boys received Testosterone Enantate (250 mg I.M./month for four doses; five of them had previously received clonidine. The GV before Testosterone, 5.0 :t 2.59 compared to post-testosterone, 9.26 :t 2.4 cm/year was significantly lower (P< 0.01 . The delay In skeletal maturation, as defined by the bone age/chronological age Index, dld not have any bearing on the eventual response to clonldine, nor this response was attributable to a progress In the sexual maturity index (Tanner during treatment with clonidine. We conclude that a subnormal spontaneous GV (Iess than 4 cm/year in these children may have a predictive value for an eventual response to clonidine treatment. Yet, more cases need to be studied to be able to draw finer conclusions.

    Los sujetos de este estudio fueron 15 niños y 6 niñas con retraso constitucional del crecimiento (edad 13.4 :t 3.1 años, rango 10.9-16. Trece niños y una niña se encontraban en la etapa prepuberal al Iniciar el estudio. Con el fin de observar la velocidad de crecimiento (VC espontánea, los pacientes fueron seguidos por un periodo de cuatro meses antes de Iniciar el tratamiento. Los niños menores de 13 años y todas las niñas recibieron clonidina durante 4 a 12 meses (0.1 mg/m2/día. Con ésta, el grupo de niños Incrementó su velocidad de crecimiento de 5.9 :t 3.12 a 7.04 :t 2.23 cm/año y las niñas de 5.53 :t 2.31 a 6.45 :t 1.18 cm/año (Ns. Sin embargo, hubo dos grupos claramente discernibles: los que respondieron a la clonidina y los que no lo hicieron. En los niños que respondieron la VC espontánea antes de la clonidina fue significativamente menor que la de los que no respondieron (3.8 :t 3.27 vs. 7.67 :t 1.66 cm/año ( p < 0.05. Para las niñas las cifras fueron 3.5 :t 0.86 y 7.57 :t 0.4 cm/año, respectivamente (p < 0.01 . Nueve niños recibieron enantato de testosterona (250 mg IM/mes por cuatro dosis; cinco de ellos hablan recibido clonidina previamente. La VC antes de la testosterona (5.0 :I: 2.59 cm/año en comparación con post- testosterona (9.26 :I: 2.4 cm/año ,fue significativamente menor (p < 0.01 . El retraso de la maduración esquelética definido por el indice edad ósea/edad cronológica no influyó en la respuesta eventual a la clonidina, ni tal respuesta fue atribuible a un incremento en el índice de maduración sexual (Tanner durante el tratamiento con esta droga. Se concluye que una velocidad de crecimiento espontánea subnormal (menos de 4 cm/año parece tener un valor predictivo para una eventual respuesta de estos niños a la clonidina. Se necesita un mayor número de casos para conclusiones más definitivas.

    2014-06-01

    Full Text Available A lo largo de décadas de actividad carbonífera en la cuenca de Río Turbio ubicada al sudoeste de la provincia de Santa Cruz en la República Argentina, se ha generado una serie de pasivos ambientales entre los cuales se encuentran los depósitos de material estéril denominados escombreras, las piletas de lodos y los sedimentos del curso de agua receptor de efluentes, el arroyo San José. La presencia de estos pasivos, ha ocasionado en distintas partes del mundo complicaciones debido a la naturaleza ácida de las escorrentías que afectan directamente fuentes de agua, superficiales y subterráneas, localizadas en la vecindad de dichos depósitos. El problema se produce cuando dicha acidez no puede ser neutralizada, lo cual ocasiona la generación de lixiviados de metales pesados en las escombreras o redisolución de los que se encuentran depositados como sedimentos en los cursos superficiales. Por tal motivo en este trabajo se realiza una evaluación preliminar del contenido metálico de los depósitos de estériles y de los sedimentos del arroyo San José y de la capacidad de generación ácida de los primeros. Se pretende con ello obtener una información básica que permita un diseño experimental científico para caracterizar dichos depósitos y evaluar el impacto que están produciendo. Como conclusión se pudo corroborar la hipótesis inicial de existencia de contenido metálico en escombreras y sedimentos y un potencial neto de generación ácida de las primeras. Además se determinó la necesidad de investigar el origen de altos contenidos metálicos en sedimentos de zonas alejadas de la producción.

This type of Zeolite with the main channel of a minimum free diameter of 0,41 nm and a low SiO2/Al2O3 ratio is an interesting molecular sieve, which in turn display a high ion exchange capacity. From this point of view, LTA Zeolite crystals were obtained “in situ” by hydrothermal synthesis and characterized by x ray diffraction (XRD and scanning electron microscopy (SEM. We have studied the effect of hydrothermal synthesis time at 378 K. Likewise, the removal capacity of heavy metal from the active phase was evaluated in as a first step on diluted solutions of cooper salts at slightly acidic pH (~ 4,7.

Os resultados obtidos vieram demonstrar que houve um pequeno aumento de produção quando se subdividiu o nitrogênio três ou quatro vêzes, aumento êsse mais substancial no ano em que foi mais acentuada a queda pluviométrica durante o período de cultivo da batatinha. Quanto ao potássio, já não verificamos esse fato, pois, tanto aplicando-o em uma só vez como em três ou quatro, os resultados foram praticamente semelhantes. Em relação ao tipo dos tubérculos, também não foram notadas diferenças acentuadas entre os diversos lotes adubados.The effects of nitrogen and potash when applied once or in several parcels to potatoes was compared in a series of experiments carried out in a soil of the glacial type. Nitrogen was applied as Chilean nitrate and potash, as potassium chloride. One, 2, 3, and 4 applications of the two fertilizers were compared in 3 separate experiments each. Results of the tests indicated that there was a small gain in yield when nitrogen was applied 3 or .4 times during the growing period. The increase in yield was substantially greater in one experiment that received heavy rains. Parcelling out the potash did not induce any increase in yield when compared with a single application. No definite difference in the size or type of tubers was noticed between the lots that received the various fertilizer treatments.

El objetivo del presente trabajo es mostrar lo que se puede esperar del tejido adiposo como origen de células adultas de fracción vacular estromal (FVE, y señalar las mejores áreas del cuerpo humano para ser elegidas como donantes de tejido adiposo, extraído mediante liposucción. Describimos la rutina seguida para la obtención de células de FVE mediante la digestión de las muestras de tejido adiposo humano con colagenasa. En el momento de su recolección, esas células presentaban una viabilidad de 92+/- 1% basada en exclusión por Azul de Trypan. Las células de FVE recontadas después de permanecer 48 horas en medio de cultivo de Eagle modificado por Dulbecco (DMEM, dentro de una cámara de Neubauer, tras lo cual el rendimiento medio de las células de FVE fue de 7,2 +/- 1,3 x 103 células por mililitro de tejido lipoaspirado. En conclusión, pensamos que supone un desafío en la actualidad el mejorar las estrategias para la obtención de células de FVE. Este trabajo, por ahora preliminar, muestra que las células de FVE pueden ser fácilmente obtenidas por medio de lipoaspiración. La comparación entre las diferentes áreas donantes, mostró un rendimiento 22% más alto para las células de FVE cuando el tejido adiposo había sido obtenido del tronco, en comparación a cuando lo había sido de los miembros.

    Full Text Available http://dx.doi.org/10.5007/2175-795X.2016v34n2p365 O presente artigo visa à sistematização dos resultados de estudos preliminares sobre os desafios e possibilidades de desenvolvimento de um trabalho de cooperação internacional compartilhada em Timor-Leste. Nesse sentido, partindo da problematização do papel da Cooperação Internacional para o Desenvolvimento nos países em desenvolvimento, tem-se como hipótese inicial que, após a restauração da independência, em 2002, e com a chegada das agências internacionais de cooperação, que aportaram em Timor-Leste com o objetivo de “ajudar” na construção do Estado-Nação, o maior desafio que o país vive é o enfrentamento da contradição entre, por um lado, atender às exigências das agências internacionais, capitaneadas pela Organização das Nações Unidas e pelo Banco Mundial, para colocar o Estado timorense e suas instituições nos trilhos da “globalização” e, por outro, defender e preservar sua identidade cultural. Portanto, com base em estudos de natureza bibliográfica, nos pressupostos teórico-metodológicos da dialética marxista e no pensamento de Paulo Freire, bem como na experiência vivida pelos autores por meio do Programa de Qualificação de Docentes e Ensino de Língua Portuguesa em Timor-Leste, conclui-se que o compromisso, a vontade política e o respeito pelas diferenças culturais entre os agentes envolvidos nas ações de cooperação são ingredientes necessários para superar os desafios e avançar na construção de uma relação de cooperação internacional compartilhada.

    Full Text Available Communicate knowledge generated in research institutions is a communicational act inherent in the scientific process, is an act of diffuse scientific information so the scientific community can develop and deepen that knowledge - dissemination, but also that society can become aware of the role of those knowledges in improving their quality of life - divulgation. In this sense, both the spread, as the spread of science communication practices are relevant to this diffusion. This article discusses these practices, bypassing a debate and positioning related to science and technology, some of its historical and theoretical perspectives. From this input we intend to establish some conceptualizations so the field research can be better availed. It starts from the assumption that the dissemination of science in the media can build a culture of assimilation of scientific information among population in general. As a problem of reflection, we put into question the scientific divulgation at the expense of serving massive recurrent themes related to the current crisis in the brazilian government and the presidential elections. From this context, the nature of this work is based on a theoretical and a critical reflection about the process of disseminating scientific knowledge on the presence of massive political and electoral issues in the media in general. The procedure can be characterized as a work of literature review. This work is contained in studies that have been conducted by the research group Media and Dissemination of Science and Technology, linked to CAPES.

    Luiz Fernando de Barros Campos

    Full Text Available Based on Erving Goffman's work, the article aims to discuss a definition of information centered on the type conveyed by individuals in a multimodal way, encompassing language and body in situations of co-presence, where face-to-face interaction occurs, and influencing inter-subjective formation of the self. Six types of information are highlighted: material information, expressive information, ritualized information, meta-information, strategic information, and information displays. It is argued that the construction of this empirical object tends to dissolve the tension among material, cognitive and pragmatic aspects, constituting an example of the necessary integration among them. Some vulnerable characteristics of the theory are critically mentioned and it is suggested that the concept of information displays could provide a platform to approach the question of the interaction order in its relations with the institutional and social orders, and consequently, to reassess the scope of the notion of social information analyzed.

    Information is essential to all human activity, and information in electronic form both amplifies and augments human information interactions. This lecture surveys some of the different classical meanings of information, focuses on the ways that electronic technologies are affecting how we think about these senses of information, and introduces an emerging sense of information that has implications for how we work, play, and interact with others. The evolutions of computers and electronic networks and people's uses and adaptations of these tools manifesting a dynamic space called cyberspace. O

    Full Text Available This article reflects on the ways of appropriation in organizations. The notion of Information Myopia is characterized by the lack of knowledge about the available informational capabilities in organizations, revealing a narrow view of the information environment. This analysis has focused on the process for renewing the software licenses contracts of a large multinational group, in order to manage its organizational assets in information technology. The collected, explained and justified information allowed to elaborate an action proposal, which enabled the creation of new organizational knowledge. In its theoretical dimension, the value of information was materialized by its use, in a collective process of organizational learning.

    The purpose of this article is to suggest a genealogy of the concept of information beyond the 20th century. The article discusses how the concept of information culture might provide a way of formulating such a genealogic strategy. The article approaches this purpose by providing a general...... narrative of premodern information cultures, examining works on early-modern scholars and 18th century savants and discussion of what seems to be a Foucauldian rupture in the conceptualization of information in 19th century England. The findings of the article are situated in the thinking that a genealogy...... of information would reveal that information had specific purposes in specific settings....

    Full Text Available Preliminary study of the fauna in the Morro de Moravia open dump and presence of heavy metals in arthropods and rodents.Characterization of the species present in a given locality by means of biological inventories provides information about diversity, even ifit is done in disturbed environments such as open dumps, which are considered a threat for health due to the accumulation of heavy metalsthat are well known for their negative effects on human health and the environment. Objectives. To carry out a preliminary characterizationof arthropods and non-flying small mammals in the Morro de Moravia open dump, and to determine the heavy metal contents in animaltissue samples. Materials and Methods. Arthropods were collected with pitfall traps and manually. Rodents were captured with Shermantraps. The heavy metal analysis was carried out with atomic spectroscopy. Results. A total of 9 orders, 51 families and 75 morphospeciesof insects, 5 families of spiders, two syrphid and a millipede species were identified; Mus musculus was the only small mammal speciesidentified. Heavy metal analysis showed various concentrations mainly of Pb and Cd. The highest content of Pb (45.05 mg/kg was foundin samples of M. musculus and the highest Cd content (10.31 mg/kg was found in spiders of the family Gasteracantha. Conclusions. TheMorro de Moravia open dump provides conditions that allow the establishment of an arthropod community with various diets and niches.The transference of heavy metals from the residue matrix towards higher levels of the trophic chain was corroborated.

    Full Text Available PURPOSE: We preliminarily investigated the relevance of performing digital subtraction angiography (DSA in addition to magnetic resonance angiography (MRA in definition of ischemic stroke etiology in young patients. METHOD: DSAs and MRAs from 17 young patients with nonlacunar ischemic stroke were blindly analyzed and their impact on stroke management was evaluated. RESULTS: Etiologies were the same considering results of either DSA or MRA in 12/17 cases. In 15/17 patients no changes would have been made in treatment, regardless of the modality of angiography considered. CONCLUSION: These preliminary results suggest that DSA may be redundant in two thirds of ischemic strokes in young patients. Further larger prospective studies are necessary to determine indications of DSA in this age group.PROPÓSITO DO ESTUDO: Investigar de forma preliminar a relevância da realização de angiografia digital (AD adicionalmente a angioressonância (AR na definição de etiologias de acidente vascular cerebral isquêmico (AVCI em pacientes jovens. MÉTODO: ADs e ARs de 17 pacientes jovens com AVCIs não-lacunares foram analisadas. Avaliamos o impacto destes exames no manejo clínico dos casos. RESULTADOS: Em 12/17 casos, as etiologias dos AVCIs de acordo com os resultados de AD ou de AR foram idênticas. Em 15/17 pacientes, nenhuma mudança de conduta terapêutica seria realizada, independentemente da modalidade de exame considerada. CONCLUSÃO: Estes resultados preliminares sugerem que os resultados da AD podem ser redundantes em relação à AR em até dois terços dos pacientes jovens com AVCI. Estudos prospectivos maiores são necessários para otimizar o estabelecimento de indicações de AD nesta faixa etária.

    Full Text Available Contemporary and future cities are often labeled as "smart cities," "ubiquitous cities," "knowledge cities" and "creative cities." Informational urbanism includes all aspects of information and knowledge with regard to urban regions. "Informational city" is an umbrella term uniting the divergent trends of information-related city research. Informational urbanism is an interdisciplinary endeavor incorporating on the one side computer science and information science and on the other side urbanism, architecture, (city economics, and (city sociology. In our research project on informational cities, we visited more than 40 metropolises and smaller towns all over the world. In this paper, we sketch the theoretical background on a journey from Max Weber to the Internet of Things, introduce our research methods, and describe main results on characteristics of informational cities as prototypical cities of the emerging knowledge society.

    Full Text Available The Simuliidae is a family of Diptera with approximately 2072 described species worldwide. The females of the majority of the species feed from vertebrates' blood, which makes them a significant plague that affects both men as well as cattle, birds, and other vertebrates. The objective of this paper is to create an inventory of Simuliidae and to reveal certain aspects of the biology and distribution of this family of aquatic insects in the Nahuel Huapi National Park. Moreover, information on the zoogeography of Simuliidae in Patagonia is provided. Five genera, 3 subgenera and 32 species Simuliidae are recorded from Patagonia: Cnesia (three spp., Cnesiamima (one sp., Gigantodax (14 spp., Paraustrosimulium (one sp., Simulium (Ectemnaspis (one sp., S. (Psaroniocompsa (one sp. and S.

    Informal payments are a frequently overlooked source of local public finance in developing countries. We use microdata from ten countries to establish stylized facts on the magnitude, form, and distributional implications of this "informal taxation." Informal taxation is widespread, particularly in rural areas, with substantial in-kind labor payments. The wealthy pay more, but pay less in percentage terms, and informal taxes are more regressive than formal taxes. Failing to include informal taxation underestimates household tax burdens and revenue decentralization in developing countries. We discuss various explanations for and implications of these observed stylized facts.

    2001-08-01

    Full Text Available In order to conduct a preliminary evaluation of the conditions allowing for a General Theory of Health, the author explores two important structural dimensions of the scientific health field: the socio-anthropological dimension and the epistemological dimension. As a preliminary semantic framework, he adopts the following definitions in English and Portuguese for two series of meanings: disease = patologia, disorder = transtorno, illness = enfermidade, sickness = doença, and malady = moléstia. He begins by discussing some sociological theories and biomedical concepts of health-disease, which, despite their limitations, can be used as a point of departure for this undertaking, given the dialectical and multidimensional nature of the disease-illness-sickness complex (DIS. Second, he presents and evaluates some underlying socio-anthropological theories of disease, taking advantage of the opportunity to highlight the semeiologic treatment of health-disease through the theory of "signs, meanings, and health practices". Third, he analyzes several epistemological issues relating to the Health theme, seeking to justify its status as a scientific object. Finally, the author focuses the discussion on a proposal to systematize various health concepts as an initial stage for the theoretical construction of the Collective Health field.Com o objetivo de avaliar preliminarmente as condições de possibilidade de uma Teoria Geral da Saúde, explora-se duas das mais importantes dimensões estruturantes do campo científico da saúde: a dimensão sócio-antropológica e a dimensão epistemológica. Como marcação semântica preliminar, propõe-se uma fixação de sentido em Português para duas séries significantes: disease = patologia, disorder = transtorno, illness = enfermidade, sickness = doença, malady = moléstia.

MATERAL E MÉTODOS: Através de um acordo com a PANLAR, o protocolo Biobadaser foi utilizado como modelo para a implementação de um novo registro no nosso país. Durante os dois primeiros anos desse esforço, o protocolo original foi adaptado, traduzido e apresentado a todos os reumatologistas brasileiros. Durante dez meses, dados de 1.037 pacientes (750 tratados com biológicos e 287 controles de 15 centros foram coletados. RESULTADOS: A maioria dos pacientes tinha artrite reumatoide (AR (n = 723. Infliximabe foi o agente anti-TNF mais usado, e a exposição total a biológicos foi 2.101 pacientes-ano. A razão mais comum para suspensão da droga foi ineficiência ou perda de efetividade (50%, e 30% dos pacientes interromperam o tratamento devido a eventos adversos. Três casos de tuberculose foram observados no grupo biológico, representando maior incidência do que aquela da população brasileira geral. Infecções foram observadas em 23% dos pacientes do grupo biológico, sendo o trato respiratório superior o local mais comumente afetado. Apenas um caso de hanseníase tuberculoide foi observado. Nenhuma morte nem malignidade atribuível ao efeito dos medicamentos foi observada até fevereiro de 2010. CONCLUSÕES: A implementação do registro foi bem sucedida.

    Full Text Available OBJETIVO: Avaliar os resultados preliminares da técnica de epifisiodese temporária utilizando-se as placas de Sherman no tratamento de distúrbios e deformidades dos membros inferiores. MÉTODOS: Foram avaliados, retrospectivamente, 27 pacientes submetidos à epifisiodese temporária do fêmur distal ou tíbia proximal com as placas de Sherman, em um total de 28 procedimentos. A idade média no momento da cirurgia foi de 11,2 anos (3-15 anos. Os implantes de dois furos eram confeccionados em liga de aço e apresentavam um orifício central para ser utilizado como guia. A fixação foi feita com dois parafusos canulados de 3,5mm. As indicações para o tratamento foram os desvios angulares dos membros inferiores em valgo (n = 10, varo (n = 2 e mistos (n = 1; discrepância do comprimento dos membros (n = 9; e contratura em flexo do joelho (n = 5. RESULTADOS: O tempo médio de seguimento foi de 11,78 meses (±4,07. Observamos apenas um evento adverso (migração do implante em um paciente submetido à epifisiodese anterior do fêmur distal para correção de flexo de joelho. Não houve nenhum caso de quebra do material ou fechamento fisário prematuro. CONCLUSÃO: A técnica de epifisiodese temporária com o uso das placas de Sherman mostrou ser de fácil execução e esteve envolvida com um baixo índice de complicações e custo inferior aos implantes similares em titânio.

La mucosectomía circunferencial con máquina de autosutura descrita por Longo como técnica para el tratamiento de las hemorroides de grado III y IV se ha extendido en los últimos años. El objetivo del presente estudio es analizar los resultados preliminares obtenidos con esta técnica. MÉTODOS. Durante un período de 16 meses fueron intervenidos 50 pacientes con patología hemorroidal sintomática de grado III-IV, y se analizó el tiempo quirúrgico y las complicaciones posoperatorias. Para la medición del dolor se recurrió a una escala analógica visual. RESULTADOS. El tiempo quirúrgico medio fue de 22 min y la estancia media postoperatoria de 2,3 días. Entre las complicaciones posoperatorias, se registraron 2 pacientes (4 % reintervenidos por sangrado y 4 pacientes (8 % precisaron sondaje vesical por retención urinaria. La intensidad del dolor en el primer día posoperatorio fue: intenso en 6 pacientes (12 %, medio en 10 (20 %, leve en 30 (60 % y nulo en los 4 restantes (8 %. Durante el tiempo de seguimiento ningún paciente ha referido incontinencia postoperatoria, ni se ha encontrado estenosis en la línea de grapado. CONCLUSIONES. Nuestra experiencia a corto plazo ha sido satisfactoria. Es una técnica sencilla y segura, con una curva de aprendizaje corta. La principal complicación postoperatoria, el dolor, se comportó de forma similar a lo que han publicado otros autores y fue fácilmente controlado con antiinflamatorios no esteroideos.

    In the fourth century, during the Chinese Dong Jin dynasty, the doctor Ge Hong described good results after the oral administration of a suspension prepared from human faeces in patients with severe diarrhoea or food poisoning. Faecal microbiota transplantation has been used for five years in order to treat different diseases in addition to the severe diarrhoea caused by Clostridium difficile 1 . This paper aims to confirm that intestinal microbiota transplantation succeeds in reducing the negative impact of diseases such as severe diarrhoea, irritable bowel syndrome, anxiety, allergies, metabolic syndrome and others and that it is not only indicated for severe diarrhoea caused by C. difficile. This preliminary study included six patients who underwent faecal microbiota transplantation, aged 83, 76, 66, 37 and 36 years (four men and two women). An improvement in symptoms of 70% was observed. The methodology and criteria to be followed with donors are described and the results are listed in three tables. The methodology followed for the microbiota transplant is the same as that reported by other researchers for the treatment of C. difficile diarrhoea and other diseases. The discussion addresses the issues raised in other parts of the world in handling different pathologic entities, as well as genetic advances. The conclusions show encouraging results.

    1948-12-01

    Full Text Available En una provincia del Perú donde es, endémica la Leishmaniosis tegumentaria conocida con el nombre de Uta, por espacio de algo más de dos años se han llevado a cabo detenidos estudios en busca del reservorio de dicha enfermedad, comprendiendo estas investigaciones principalmente a los, animales domésticos de la región. La primera serie, de observaciones, realizadas entre Mayo, 1945 y julio, 1946, consta de 469 animales. Durante este período el autor esperaba encontrar en los animales infectados lesiones de la piel ulceradas en forma semejante a lo que sucede en el hombre, cosa que no le fué posible verificar en ningún caso. Informado del aspecto macroscópico de las lesiones en el perro, por medio de infecciones experimentales que obtuviera en el laboratorio, prosiguió sus observaciones con 496 animales más, consiguiendo demostrar la infecciones natural en 40 perros. Un hecho importante en estas infecciones es que con frecuencia no dan lugar a ninguna alteración macroscópica de la piel. La incidencia de la infección natural del perro coincide en líneas generales con la humana, además de que en varias oportunidades los animales infectados procedían de las mismas habitaciones donde había uno o más casos de leishmaniosis tegumentaria entre sus dueños.

  8. Spacetime information

    In usual quantum theory, the information available about a quantum system is defined in terms of the density matrix describing it on a spacelike surface. This definition must be generalized for extensions of quantum theory which neither require, nor always permit, a notion of state on a spacelike surface. In particular, it must be generalized for the generalized quantum theories appropriate when spacetime geometry fluctuates quantum mechanically or when geometry is fixed but not foliable by spacelike surfaces. This paper introduces a four-dimensional notion of the information available about a quantum system's boundary conditions in the various sets of decohering, coarse-grained histories it may display. This spacetime notion of information coincides with the familiar one when quantum theory is formulable in terms of states on spacelike surfaces but generalizes this notion when it cannot be so formulated. The idea of spacetime information is applied in several contexts: When spacetime geometry is fixed the information available through alternatives restricted to a fixed spacetime region is defined. The information available through histories of alternatives of general operators is compared to that obtained from the more limited coarse grainings of sum-over-histories quantum mechanics that refer only to coordinates. The definition of information is considered in generalized quantum theories. We consider as specific examples time-neutral quantum mechanics with initial and final conditions, quantum theories with nonunitary evolution, and the generalized quantum frameworks appropriate for quantum spacetime. In such theories complete information about a quantum system is not necessarily available on any spacelike surface but must be searched for throughout spacetime. The information loss commonly associated with the ''evolution of pure states into mixed states'' in black hole evaporation is thus not in conflict with the principles of generalized quantum mechanics

    The paper is a general one reviewing the detailed experimental and theoretical work that has been done during design, development and commissioning of the Windscale AGR. and in general support of development of Advanced Gas-Cooled Reactors for civil power production. The main purpose of the paper is to describe die considerable amount of work that has been necessary to develop adequate theoretical methods for calculating (a) flux distribution and reactivity balance in a complex reactor core, (b) power distribution in complex fuel geometries, and (c) the effect of irradiation on fuel cycles and power distribution. As an introduction reference is made to experimental information and theoretical methods available from work on uranium Magnox systems and the experimental information obtained from the British Industries Collaborative Experimental Programme (BICEP) both of which provided the starting point for development of theoretical methods applicable to AGRs. The approach to critical facility APEX and the zero energy reactor HERO have been used with regular lattice arrangements and with combinations of perturbers such as control rods in them to determine lattice parameters for AGR and to check the theoretical methods developed for dealing with heterogeneous reactor cores. The theoretical methods that have been developed and used to date are known as hetrecontrol and FTD2. Experiments were designed to check detailed features of these methods and measurements on a number of different sized ''reactor'' cores in APEX and HERO were analysed to determine a self-consistent set of lattice constants that fitted the experimental results. These purely empirical constants were the used in hetrecontrol and FTD2 to successfully plan commissioning and choice of the loading pattern for the Windscale AGR. Reference is made to experimental techniques that have been tested and those developed for the particular problems encountered. The methods examined for measurement of reactivity

    During the reception of a piece of information, we are never passive. Depending on its origin and content, from our personal beliefs and convictions, we bestow upon this piece of information, spontaneously or after reflection, a certain amount of confidence. Too much confidence shows a degree of naivety, whereas an absolute lack of it condemns us as being paranoid. These two attitudes are symmetrically detrimental, not only to the proper perception of this information but also to its use. Beyond these two extremes, each person generally adopts an intermediate position when faced with the recep

    2003-01-01

    A fiduciary relationship should be nurtured between patient and physician. This requires effective communication throughout all aspects of care - especially pertaining to treatment decisions. In the context of illness as experienced by the patient a unique set of circumstances is presented. However, communication in an illness context is fraught with problems. The patient is vulnerable and the situation may be overwhelming. Voluminous amounts of information are available to patients from a host of health care providers, family members, support groups, advocacy centers, books, journals, and the internet. Often conflicting and confusion, frequently complex, this information may be of greater burden than benefit. Some information is of high validity and reliability while other information is of dubious reliability. The emotional freight of bad news may further inhibit understanding. An overload of information may pose an obstacle in decision-making. To facilitate the transformation of information into knowledge, the health care provider must act on some occasions as a filter, on other occasions as a conduit, and on still other occasions simply as a reservoir. The evolution of patient rights to receive or refuse treatment, the right to know or not to know calls for a change in processing of overwhelming information in our modem era. In this paper we will discuss the difference between information and knowledge. How can health care providers ensure they have given their patients all necessary and sufficient information to make an autonomous decision? How can they facilitate the transformation of information into knowledge? The effect of knowledge to consent allows a more focused, relevant and modern approach to choice in health care.

    Full text: An information barrier (IB) consists of procedures and technology that prevent the release of sensitive information during a joint inspection of a sensitive nuclear item, and provides confidence that the measurement system into which it has been integrated functions exactly as designed and constructed. Work in the U.S. on radiation detection system information barriers dates back at least to 1990, even though the terminology is more recent. In January 1999 the Joint DoD-DOE Information Barrier Working Group was formed in the United States to help coordinate technical efforts related to information barrier R and D. This paper presents an overview of the efforts of this group, by its Chairs, as well as recommendations for further information barrier R and D. Progress on the demonstration of monitoring systems containing IBs is also provided. From the U.S. perspective, the basic, top-level functional requirements for the information barrier portion of an integrated radiation signature-information barrier inspection system are twofold: The host must be assured that his classified information is protected from disclosure to the inspecting party; and The inspecting party must be confident that the integrated inspection system measures, processes, and presents the radiation-signature-based measurement conclusion in an accurate and reproducible manner. It is the position of the United States that in the absence of any agreement to share classified nuclear weapons design information in the conduct of an inspection regime, the requirement to protect host country classified warhead design information is paramount and admits no tradeoff versus the confidence provided to the inspecting party in the accuracy and reproducibility of the measurements. The U.S. has reached an internal consensus on several critical design elements that define a general standard for radiation signature information barrier design. These criteria have stood the test of time under intense

A idade dos pacientes variou de 15-50 anos (média de 23,9 anos e o tempo médio de acompanhamento das pulpotomias foi de 34,52 meses. Avaliações clínicas e radiográficas foram realizadas para a avaliação das pulpotomias. Ausência de hipersensibilidade, de alterações periapicais e teste de vitalidade pulpar positivo, eram as condições necessárias para que o tratamento fosse incluído no grupo "clinicamente favorável" utilizados para avaliar a condição clínica dos dentes tratados. Os critérios de avaliação clínica da USPHS foram utilizados para avaliar a qualidade das restaurações. Dez dentes (43,5% receberam o escore clinicamente favorável, 4 anteriores e 6 dentes posteriores. O critério falha foi atribuído a 13 dentes (56,5%, 4 dentes anteriores e 9 posteriores. Entre os dentes do grupo clinicamente favorável, 90% das restaurações foram classificadas como clinicamente satisfatória, enquanto 10% estavam insatisfatórias. No grupo onde houve falha, 77,8% das restaurações foram classificadas como insatisfatória enquanto 22,2% foram classificadas como satisfatórias. A análise estatística (Teste exato de Fisher demonstrou que existe uma associação estatisticamente significante entre a condição clínica da pulpotomia e a qualidade da restauração (p<0,05. Respeitando as limitações do estudo, é possível verificar que a qualidade da restauração pode ser um fator influente para uma condição clínica favorável de dentes tratados com pulpotomia. Estudos clínicos controlados são necessários para confirmar esses achados preliminares.

Desta forma, este trabalho reporta o estudo preliminar toxicológico, antibacteriano e fitoquímico do extrato etanólico das folhas de Jatropha mollissima (pinhão-bravo, Euphorbiaceae, coletada no Município de Tauá, Ceará, Nordeste Brasileiro. Inicialmente, realizou-se o teste de toxicidade do extrato contra Artemia salina. Na sequencia, foi realizado o ensaio antibacteriano contra quatro cepas bacterianas Gram-negativas (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Hafnia alvei ATCC 51873, Klebsiella pneumoniae ATCC 13883 e uma cepa Gram-positiva (Enterococcus faecalis ATCC 29212. Finalmente, fez-se a análise fitoquímica preliminar do extrato ativo para detecção das principais classes de metabólitos especiais. Como resultado, o extrato etanólico das folhas de J. mollissima se mostrou tóxico para Artemia salina, pois apresentou CL50 igual a 406,02 μg/mL. Quanto à ação antibacteriana, o extrato se mostrou ativo contra a bactéria Gram-positiva Enterococcus faecalis ATCC 29212, apresentando moderada atividade antibacteriana (halo de inibição igual a 7,03 mm. Evidenciou-se no extrato bioativo a presença de cumarinas, fenóis, taninos, flavonoides (flavonóis e flavanonas, alcaloides e esteroides, ambas as classes reportadas como antimicrobianos. Portanto, esse extrato tem potencial para ser usado na produção de fármacos contra infecções causadas por bactérias Gram-positivas. No entanto, as informações direcionam estudos futuros para o isolamento e identificação dos compostos bioativos, monitorados sob a ação antibacteriana mais expressiva.

    At present, fertilizer plants are considered as one of the main sources of potentially contaminated areas in Russia. In this paper, an interesting experimental case-study area located in Moscow Region has been considered for the preliminary health cancer risk assessment for arsenic exposure. Arsenic has been selected as the individual contaminant indicator, according to a specific, original selection procedure presented in the paper. For estimating the human exposure to arsenic through multiple pathways, the original McKone and Daniels 91 model has been used. As a result of this preliminary assessment step for the case-study area, the calculated individual cancer risk levels for arsenic exposure through (in risk ranking order) consumption of agricultural products - consumption of drinking water - dermal contact - direct soil ingestion - ingestion of dairy products are significant. The present paper could be assumed too as a contribution (for comparison and stimulus) to the actual, Italian situation of soil quality criteria, especially regarding the agricultural land use. [Italian] Le aree interessate dalla presenza di impianti di produzione di fertilizzanti, rappresentano attualmente una rilevante sorgenti di siti potenzialmente contaminati in Russia.

    Full Text Available Non-bacterial thrombotic endocarditis (NBTE is a rare cause of systemic embolism. It is most frequently seen in patients with advanced cancer disease or chronic inflammation. It is usually a post mortem diagnosis, however there are patients who are diagnosed before death and it usually presents with signs and symptoms of systemic embolisms. Rapid recognition of this entity is often important to initiate early treatment. We present a patient with pancreatic cancer and neurological symptoms who attends the emergency room.

    Full Text Available El trabajo se inicia mostrando la relación que se estableció entre la filosofía de la ciencia, la psicología del aprendizaje y la didáctica de las ciencias, que lleva a la consolidación de ésta, en particular, con los estudios de las concepciones alternativas. Pero las dificultades de los estudiantes no pueden reducirse a las concepciones alternativas. Por eso es conveniente ampliar el concepto de dificultades de aprendizaje e incluir dificultades debidas al razonamiento de 'sentido común', a las actitudesnegativas de los estudiantes, etc. En consecuencia, un cambio exclusivamente conceptual no tiene en cuenta estas nuevas dificultades y son necesarios otros cambios. Pero sobre ellos existe bastante confusión terminológica que intentamos aclarar.

    The AP1000 is a design of a nuclear reactor of pressurized water (PWR) of 1000 M We with characteristic of safety in a passive way; besides presenting simplifications in the systems of the plant, the construction, the maintenance and the safety, the AP1000 is a design that uses technology endorsed by those but of 30 years of operational experience of the PWR reactors. The program AP1000 of Westinghouse is focused to the implementation of the plant to provide improvements in the economy of the same one and it is a design that is derived directly of the AP600 designs. On September 13, 2004 the US-NRC (for their initials in United States- Nuclear Regulatory Commission) approved the final design of the AP1000, now Westinghouse and the US-NRC are working on the whole in a complete program for the certification.

    Full Text Available Os aços 9%Cr são amplamente utilizados à alta temperatura, principalmente em aplicações relacionadas à geração de energia. Ultimamente têm sido desenvolvidas variantes desses materiais incorporando B, W e Co, entre outros elementos, ao sistema de liga. Devido à escassez de informação sobre a influência do procedimento de soldagem sobre a junta soldada, neste trabalho se estudou o comportamento do metal base e do metal de solda em juntas circunferências soldadas com dois consumíveis diferentes pelo processo de soldagem semi-automático FCAW, sob proteção gasosa de Ar/20%CO2. Realizaram-se tratamentos térmicos pós-soldagem a 760ºC durante 4 e 2 horas. Utilizaram-se dois arames tubulares de escória rutílica, ligados ao 9Cr1Mo e 9Cr0,5Mo1WCo. Analisou-se a microestrutura nas zonas do metal de solda, afetada pelo calor (zonas de grão grosso, grão fino, intercrítica e subcrítica e metal base. Determinaram-se a composição química do metal de solda e as propriedades de tração transversal da junta, e realizaram levantamento do perfil de microdureza. Em todos os casos se observaram valores máximos de dureza na zona correspondente ao metal de soldadura e uma diminuição na zona afetada pelo calor desde a zona de grão grosso até o metal base, obtendo se valores mínimos na zona intercrítica, inferiores aos correspondentes ao aço base. Tanto a dureza como a resistência à tração aumentaram quando foi utilizado o arame 9Cr0,5Mo1W. O tratamento térmico mais curto permitiu alcançar maior resistência em todos os casos. Numa próxima etapa se fará as medições de tenacidade e de resistência ao creep.

    Full Text Available Starting from its historical origins, capitalism has developed an increasingly complex and conflictive emotional culture that has culminated in the expressive individualism that is characteristic of neoliberal globalization. Post-Fordism has developed intense forms of emotional self-examination and cultivated a desire to overcome the traditional contradiction between the Calvinistic asceticism proper to the world of work and the hedonism of consumer society. The result should have been a “democracy of the emotions” that would relax the class conflict and extend progressive civic culture to the intimate sphere by means of fluent emotional communication. However, as communitarian criticism soon pointed out, neoliberal emotivism has instead led to an ethical de-foundation that has driven capitalist societies to subjective inclemency, damaged lives and emotional malaise as demonstrated by the contemporary epidemic of psychiatric disorders relating to the individual’s state of mind.

    2017-01-01

    The book provides a comprehensive introduction and a novel mathematical foundation of the field of information geometry with complete proofs and detailed background material on measure theory, Riemannian geometry and Banach space theory. Parametrised measure models are defined as fundamental geometric objects, which can be both finite or infinite dimensional. Based on these models, canonical tensor fields are introduced and further studied, including the Fisher metric and the Amari-Chentsov tensor, and embeddings of statistical manifolds are investigated. This novel foundation then leads to application highlights, such as generalizations and extensions of the classical uniqueness result of Chentsov or the Cramér-Rao inequality. Additionally, several new application fields of information geometry are highlighted, for instance hierarchical and graphical models, complexity theory, population genetics, or Markov Chain Monte Carlo. The book will be of interest to mathematicians who are interested in geometry, inf...

    Numerous articles on informed consent have appeared in medical and legal journals over the past few years. Many of these have been in the radiological literature. This chapter presents an overview of the legal principles behind this controversial topic. Recent articles are reviewed and specific suggestions are made where applicable. The doctrine of informed consent is both a product of and the basis for the physician-patient relationship. Their communications to each other establish the relationship, but once established, heightened degrees of expectations on the patient's part have dictated the need for a more sophisticated level of communication. Since patients and physicians often expect different things of each other, it is imperative that the relationship leads to effective and respectful conversation

    We consider research and theory relevant to the notion of informal learning. Beginning with historical and definitional issues, we argue that learning happens not just in schools or in school-aged children. Many theorists have contrasted informal learning with formal learning. Moving beyond this dichotomy, and away from a focus on where learning occurs, we discuss five dimensions of informal learning that are drawn from the literature: (1) non-didactive, (2) highly socially collaborative, (3) embedded in meaningful activity, (4) initiated by learner's interest or choice, and (5) removed from external assessment. We consider these dimensions in the context of four sample domains: learning a first language, learning about the mind and emotions within families and communities, learning about science in family conversations and museum settings, and workplace learning. Finally, we conclude by considering convergences and divergences across the different literatures and suggesting areas for future research.

    During recent decades, natural resources agency personnel and others involved with the management and stewardship of wildlife have experienced an increasing need to access information and obtain technical assistance for addressing a diverse array of wildlife disease issues. This Chapter provides a broad overview of selected sources for obtaining supplemental information and technical assistance for addressing wildlife disease issues in North America. Specifically, examples of existing major wildlife disease programs focusing on free-ranging wildlife populations are highlighted; training opportunities for enhancing within-agency wildlife disease response are identified; a selected reading list of wildlife disease references is provided; and selected Web sites providing timely information on wildlife disease are highlighted. No attempt is made to detail all the North American programs and capabilities that address disease in free-ranging wildlife populations. Instead, this Chapter is focused on enhancing awareness of the types of capabilities that exist as potential sources for assistance and collaboration between wildlife conservation agency personnel and others in addressing wildlife disease issues.

RESULTS: Hippotherapy significantly reduced the amplitude of oscillation in the anteroposterior direction in IG while CG remained unaltered. In both groups postural stability was reduced after the suppression of visual information. CONCLUSIONS: Hippotherapy induced functional adaptations that resulted in better postural stability of subjects with MS. This study corroborates literature supporting the use of hippotherapy as a possible intervention for balance disorders in patients with MS.

Os pacientes com adenocarcinoma, 3 foram tratados endoscopicamente por portarem lesão pequena e precoce, os outros 6 pacientes foram encaminhados para tratamento cirúrgico e quimioterápico. CONCLUSÕES: Os resultados preliminares são insuficientes para estimar qual foi o real efeito da campanha, contudo, pode-se antever redução da incidência de CCR a longo prazo, além de antecipação do diagnóstico e, portanto, do estádio da doença melhorando o prognóstico.BACKGROUND: The colorectal cancer accounts for about 500,000 deaths/year worldwide and ranks third in death by neoplasia. Patient mortality is directly related to its stage when diagnosed. Screening allows early diagnosis, reason why it turns out to be an effective tool to reduce mortality. AIM: To assess the impacts of the colorectal cancer prevention campaign in a Brazilian municipality, to estimate the disease occurrence and to forecast reduction of its incidence in the long term. METHODS: The Giant Colon, a replica of the human colon, created by ABRAPRECI, was exposed in the local Sports Gymnasium, in order to educate the population on the parts of the organ and the main diseases affecting it.

In the mid-1930s two influential but seemingly unrelated papers were published. In 1935 Einstein, Podolsky and Rosen proposed the famous EPR paradox that has come to symbolize the mysteries of quantum mechanics. Two years later, Alan Turing introduced the universal Turing machine in an enigmatically titled paper, On computable numbers, and laid the foundations of the computer industry one of the biggest industries in the world today. Although quantum physics is essential to understand the operation of transistors and other solid-state devices in computers, computation itself has remained a resolutely classical process. Indeed it seems only natural that computation and quantum theory should be kept as far apart as possible surely the uncertainty associated with quantum theory is anathema to the reliability expected from computers? Wrong. In 1985 David Deutsch introduced the universal quantum computer and showed that quantum theory can actually allow computers to do more rather than less. The ability of particles to be in a superposition of more than one quantum state naturally introduces a form of parallelism that can, in principle, perform some traditional computing tasks faster than is possible with classical computers. Moreover, quantum computers are capable of other tasks that are not conceivable with their classical counterparts. Similar breakthroughs in cryptography and communication followed. (author)

  2. Quantum information

    Rodgers, P

    1998-03-01

    There is more to information than a string of ones and zeroes the ability of ''quantum bits'' to be in two states at the same time could revolutionize information technology. In the mid-1930s two influential but seemingly unrelated papers were published. In 1935 Einstein, Podolsky and Rosen proposed the famous EPR paradox that has come to symbolize the mysteries of quantum mechanics. Two years later, Alan Turing introduced the universal Turing machine in an enigmatically titled paper, On computable numbers, and laid the foundations of the computer industry one of the biggest industries in the world today. Although quantum physics is essential to understand the operation of transistors and other solid-state devices in computers, computation itself has remained a resolutely classical process. Indeed it seems only natural that computation and quantum theory should be kept as far apart as possible surely the uncertainty associated with quantum theory is anathema to the reliability expected from computers? Wrong. In 1985 David Deutsch introduced the universal quantum computer and showed that quantum theory can actually allow computers to do more rather than less.

    1991-01-01

    Information demand is defined in terms of both information content (what information) and form (when, how, and where it is needed). Providing the information richness required for flight crews to be informed without overwhelming their information processing capabilities will require a great deal of automated intelligence. It is seen that the essence of this intelligence is comprehending and capturing the demand for information.

  9. Fair Value Versus Historical Cost-Based Valuation for Biological Assets: Predictability of Financial Information

    2011-12-01

    Full Text Available There is an intense debate on the convenience of moving from historical cost (HC toward the fair value (FV principle. The debate and academic research is usually concerned with financial instruments, but the IAS 41 requirement of fair valuation for biological assets brings it into the agricultural domain.This paper performs an empirical study with a sample of Spanish farms valuing biological assets at HC and a sample applying FV, finding no significant differences between both valuation methods to assess future cash flows. However, most tests reveal more predictive power of future earnings under fair valuation of biological assets, which is not explained by differences in volatility of earnings and profitability. The study also evidences the existence of flawed HC accounting practices for biological assets in agriculture, which suggests scarce information content of this valuation method in the predominant small business units existing in the agricultural sector in advanced Western countries.La evolución de la contabilidad desde el coste histórico (CH hacia el valor razonable (VR ha suscitado debates y controversias, tanto en el ámbito profesional, como en el académico. Si bien el debate y los estudios se han referido principalmente a los instrumentos financieros, el requerimiento de la NIC41 de valorar los activos biológicos al VR ha ampliado el debate a la contabilidad agrícola.Este trabajo realiza un estudio empírico mediante una muestra de explotaciones agrícolas españolas que valoran sus activos biológicos al CH y otra que valoran al VR, para comparar el poder predictivo de ambos criterios de valoración. No se encuentran diferencias significativas entre ambos criterios para la predicción de los futuros flujos de tesorería. No obstante, la mayor parte de los tests realizados revelan un mayor poder predictivo de los futuros resultados contables bajo el valor razonable, que no se explica en función de diferencias en la

    Full Text Available The combination of complex structures and diverse materials, restricts our knowledge of the biomechanics of teeth. In this sense, finite element analysis (FEA is a method used in engineering and biomechanical studies to estimate the performance and changes produced by regimes of stress and strain in mechanic structures or the human skeleton, as well as in soft tissues. On only rare occasions it is applied to the problem of biomechanical design in animals and even less in fossil groups. In this work, we advance the preliminary results obtained on creating a complete complex 3D finite element model of the tooth of an extinct deer in order to test its functionality and mechanical properties.La combinación de las complejas estructuras y de los diversos materiales que integran los dientes, restringe nuestro conocimiento acerca de su biomecánica. En este sentido, el análisis de elementos finitos (AEF es un método utilizado en ingeniería y en estudios biomecánicos para estimar el rendimiento y las variaciones producidas por las tensiones y las deformaciones en estructuras mecánicas o del esqueleto humano, así como en tejidos blandos. En contadas ocasiones se ha aplicado este método al problema de diseño biomecánico de animales y aún menos en grupos fósiles.

    This book is conceived as an introductory text into the theory of syntactic and semantic information, and information flow. Syntactic information theory is concerned with the information contained in the very fact that some signal has a non-random structure. Semantic information theory is concerned with the meaning or information content of messages and the like. The theory of information flow is concerned with deriving some piece of information from another. The main part will take us to situation semantics as a foundation of modern approaches in information theory. We give a brief overview o

    Full Text Available This paper aims to contribute to the activities planned by the IETcc on the occasion of the 60th anniversary of the journal Informes de la Construcción, including this special issue of Informes – as the journal is familiarly known within the Spanish scientific community –, which has been and continues to be the Institute’s flag bearer, its senior-most journal with the longest uninterrupted history. The paper highlights its importance as a source of information for the study of the scientific and technical development of construction in Spain over the last six decades, as well as its role in the technology transfer in construction, not only in Spain, for beyond the national borders it continues to be a benchmark in Latin America and it is present in most of the countries known for their highly advanced construction techniques.After a brief introduction on the origins of Informes in the IETcc as a vehicle for publicizing the technical novelties generated in construction, the paper analyzes the main stages in its evolution, particularly 1948-1981, 1981-2005 and from 2006 to the present. With a diachronic study, it shows the variations in the journal’s content, form – particularly its layout –, and circulation strategies. Finally, it reflects on the future in store for Informes in today’s society where access to information has changed so radically since the advent of the Internet.Este trabajo quiere contribuir a las actividades programadas por el IETcc con motivo del 60 aniversario de la Revista Informes de la Construcción, dentro de las cuales se incluye este número especial de Informes -como se le conoce coloquialmente entre sus lectores- que ha sido y sigue siendo la revista veterana y de mayor continuidad que ha tenido el Instituto.

    1999-01-01

    Full Text Available The work of managers in small and medium-sized enterprises is very information-intensive and the environment in which it is done is very information rich. But are managers able to exploit the wealth of information which surrounds them? And how can information be managed in organisations so that its potential for improving business performance and enhancing the competitiveness of these enterprises can be realised? Answers to these questions lie in clarifying the context of the practice of information management by exploring aspects of organisations and managerial work and in exploring the nature of information at the level of the organisation and the individual manager. From these answers it is possible to suggest some guidelines for managing the integration of business strategy and information, the adoption of a broadly-based definition of information and the development of information capabilities.

Our results showed that interviewers at FZB-BH associate that area almost always to leisure¿s activities while RPPN-FMA was pointed like a research¿s unit. Moreover, students at RPPN-FMA presented higher level of information about ecology and behavior of the primates than that at FZB-BH, what can be explained, among other things, by the systematic activities of environmental education developed in this protected area. Environmental education at these institutions becomes important to spread information about primate and its threats.

The model integrates evolutionary, static and dynamic views of information and highlights the relationship between symbolic content and the physical world. The model includes what information technology practitioners call “non-functional” attributes, which, for information, include information quality and information friction. The concepts developed in the model enable a richer understanding of Floridi’s questions “what is information?” and “the informational circle: how can information be assessed?” (which he numbers P1 and P12.

    This report is a synthesis of the possibilities of CO{sub 2} storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO{sub 2} storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO{sub 2} storage. (Author) 17 refs.

    A Quality Control (CQ) to ensure the expected performance of a Multileaf Collimator System (MLC) is essential for delivering dose in a safety and appropriate way. The time required for equipment control and dosimetry may be lowered when the Electronic Portal Image Device (EPID) is used. The aim of this paper was to check the resolution limits of the detection system for IMRT mode, and to do the analysis of three tests of MLC performance: Picket Fence, Slinding GAP, MLC versus Gantry. A Varian iX Clinac equipped with an 80 leaf Millennium MLC and with amorphous silicon based EPID (aS1000) was use. The EPID proved Effective, where errors up to 0,5 mm can be detected. Information about interleaf transmissions, dose profile and gravity influence in the leaf banks also were included. (author)

    Full Text Available OBJETIVOS: Descrever aspectos metodológicos e resultados preliminares de um estudo de intervenção planejado para medir o impacto de um programa de suplementação alimentar sobre a promoção do crescimento infantil de crianças desnutridas. MÉTODOS: Estudo longitudinal, controlado, desenvolvido no estado de Alagoas, com grupos comparados antes e depois da intervenção. Vinte municípios foram selecionados através de um indicador de cobertura do programa de suplementação alimentar. Essa cobertura foi estimada pela diferença entre a proporção de crianças desnutridas e a proporção de crianças atendidas pelo programa. Os dez municípios com indicador de alta cobertura foram selecionados para o grupo intervenção e aqueles de menor cobertura para o grupo controle. Em cada município do grupo intervenção foram selecionadas 15 crianças ingressando no Programa. Em cada município do grupo controle foram incluídas 15 crianças elegíveis, mas que não conseguiram vaga no Programa. RESULTADOS: Foram aplicados 111 e 102 questionários em crianças dos municípios do grupo intervenção e controle, respectivamente. A comparação em relação às características de base mostra que a distribuição das variáveis demográficas e nutricionais foi semelhante entre as crianças dos grupos intervenção e controle. Por outro lado, as crianças do grupo intervenção são provenientes de famílias com menor renda familiar e seus pais apresentaram menor escolaridade quando comparadas às do grupo controle. CONCLUSÕES: Os resultados preliminares mostram que os grupos são comparáveis em relação às variáveis demográficas e nutricionais e que as diferenças observadas quanto ao nível socioeconômico deverão ser consideradas na análise ajustada, na segunda fase do estudo.OBJECTIVE: To describe methodological aspects and preliminary results of an intervention designed to measure the impact on child growth of nutritional programs

    Full Text Available Background. The role of personal information collections is a well known feature of personal information management. The World Wide Web has introduced to such collections ideas such as filing Web pages or noting their existence in 'Bookmarks' and 'Favourites'. Argument. It is suggested that personal information collections are created in anticipation of some future need for that information-personal, anticipated information need, which also underlies the design of formal information systems. Elaboration. Examination of the literature of information needs and information seeking behaviour leads to the formulation of five propositions that elaborate the concept of personal, anticipated information need. These propositions draw upon concepts such as uncertainty, predictability, sensitivity and the valuation of information sources. Conclusion. An individual's understanding of personal, anticipated information need and how this understanding guides the acquisition and management of personal information will determine the effectiveness of that collection.

    The aim of the present work was to use the technological information available in the patent system to evaluate the technological routes used in the biodiesel production from waste cooking oil. The search for patent documents was performed in two steps: patent applications in Brazil and patent applications in others countries. The method is described in the following order: choice of the patent searching databases; data parameters definition; displaying results; quantitative and qualitative analysis of the results; and data treatment. The results allowed concluding that the technological process to obtain biodiesel from waste cooking oil mostly used was the esterification followed by transesterification. Methanol was the preferable alcohol, but, there were a great number of Brazilian patents documents using ethanol. Also, there were an increasing number of patent documents concerning the development of new catalysts. The results also showed a low number of patent documents related to the pre-treatment of waste cooking oil, what suggests the need of further research to improve and standardized the raw material quality and consequently overcome the different difficulties during the biodiesel process production.

    The various successive episodes of vertical cratogenic evolution modelling the geo tectonic features of the basement were correlated with the internal structure, shape, origin and geologic evolution of the sedimentary basin. A systematic petrologic and geochronological investigation of all available drill core samples was carried out, and the pertinent geophysical data regarding basement structure were taken into consideration. Specific geo tectonic analyses, were carried out along the borders of the sedimentary basins, within the adjacent basement. The main boundaries between Precambrian tectonic provinces, the main tectonic sutures with polycyclic evolution, and the ancient intracratonic rifts were identified wherever possible. Their extensions under the sedimentary basins were inferred, corroboration being sought from structural information and data obtained from the drill core samples. It was found that many of the identified basement discontinuities had a direct influence on the depositional history of each of the sedimentary basins, demonstrating the distinct tectonic inheritance. The subject was treated on a reconnaissance scale, 1:1.000.000 or smaller,owing to its complexity. (author)

    Although the uses of ionizing radiation in industry are subject to procedures that provide a high level of safety, experience has shown that equipment failure, human errors, or the combination of both that can trigger accidental exposures may occur. Traditionally, the radiation safety checks whether these industrial practices (industrial radiography, industrial irradiators, among others) are sufficiently safe to prevent similar accidental exposures already occurred, so that becomes dependent on the published information and not always answers questions like: What other events can occur, or what other risks are present? Taking into account the results achieved by the Foro Iberoamericano de Organismos Reguladores Radiologicos y Nucleares, its leading position in the use of techniques of risk analysis in radioactive facilities and the need to develop a proactive approach to the prevention of accidents arising from the use of ionizing radiations in the industry, it intends to apply the risk analysis technique known as Risk Matrix to a hypothetical reference entity for the region in which industrial radiography is performed. In this paper the results of the first stage of this study are shown, that is the identification of initiating events (IE) and barriers that help mitigate the consequences of such IE, so that can appreciate the applicability of this method to industrial radiography services, to reduce the risk to acceptable levels. The fundamental advantage associated with the application of this methodology is that can be applied by the professionals working in the service and identifies specific weaknesses that from the point of view of safety there, so they can be prioritized resources depending on risk reduction.

    The aim of this study was to obtain preliminary values of reference levels in CT . Were sent to each country forms with information of radiological protection and routine CT protocols. The CT dose index and absorbed dose to organs was estimated from the technical data for each equipment . The results showed that the total number of examinations performed 92 % are adult patients and 8 % are children. The most frequent examination of the skull was adult (40 % ) and abdomen for children (42 % ) . About the service , 67 % of the equipment are multicut and 76 % have specific protocols for pediatric patients. The CTDI{sub vol} values for head exams of adults vary between 2 and 352 mGy for pediatric patients under 1 year 1-191 mGy under 7 years old 5-335 mGy. For chest values ranged from 3 to 26 mGy for adults, between 1 and 89 mGy for children under 1 year and between 3-114 mGy for children between 1 and 7 years. Exams of the abdomen/pelvis of adults the range was 3-47 mGy , between 4-90 mGy for children under 1 year and between 2-31 mGy for children between 1 and 7 years. This study showed that although there are pediatric protocols, there is a wide variation in values of CTDl{sub vol} indicating a high potential for dose reduction. This result requires immediate action for optimization and implementation of diagnostic reference values in Latin America.

    Full Text Available Introduction. The article is devoted to the problem of interaction between schoolchildren and possible informational risks transmitted on the Internet. Considering the lack of external filters on the way of harmful information streams, it is actually necessary to develop information culture of schoolchildren, their abilities to sensibly and critically interpret the information on the Internet, and choice of adequate behaviour models surfing the Web. The aim of the present research is to analyze the state of informational safety of schoolchildren while using the Internet; gaining an understanding of the role of external restrictions and opportunities of intrapersonal filtration of the harmful Internet content depending on children age. Methodology and research methods. The methodology of the research is based on modern methods aimed to consider the problem of personal socialization in modern information society. Thus, the Internet Initiatives Development Fund (IIDF questionnaire let the authors define the level of awareness of recipients on the problem under consideration. Results and scientific novelty. The theoretical analysis helped the authors predict the correlation of basic methods in order to guarantee personal safety of schoolchildren taking into account the process of maturity as well as the decrease of external filters that may stop harmful content. Empirical part of the research has enabled to reveal decrease in external control of staying of a child in network in the process of growing up against the background of restrictive attitudes prevalence among teachers and parents. Therefore, the research supposed to improve information culture of schoolchildren from the earliest ages encouraging them to sensibly and correctly interpret the information on the Internet. Practical significance. The practical recommendations to parents and teachers in order to improve informational personal safety of schoolchildren are proposed. The relevancy

    Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

One of the features of contemporaneityis the global spread of ICT, combined with poor governance and other difficulties in the construction of innovation infrastructures that are based on them in some countries. This leads to the reproduction of threats, primarily related to the ability to use ICT for purposes that are inconsistent with the objectives of maintaining international peace and security, compliance with the principles of non-use of force, non-interference in the internal affairs of states, etc. In this regard, include such terms as "a threat of information warfare", "information terrorism" and so forth. Information warfare, which stay in the policy declared the struggle for existence, and relationships are defined in terms of "friend-enemy", "ours-foreign". Superiority over the opponent or "capture of its territory" is the aim of political activity. And information security, serving activities similar process of political control, including a set of components, is a technology until their humanitarian. From the context and the decision itself is the ratio of the achieved results of information and political influence to the target - a positive image of Russia. Bringing its policy in line with the demands of a healthy public opinion provides conductivity of theauthorities initiatives in the country and increases the legitimacy of the Russian Federation actions in the world.

  20. Digital Information and Value

    Directory of Open Access Journals (Sweden)

    Paul Walton

    2015-11-01

    Full Text Available Digital information changes the ways in which people and organisations interact. This paper examines the nature of this change in the context of the author’s Model for Information (MfI. It investigates the relationship between outcomes and value, selection processes and some attributes of information and explores how this relationship changes in the move from analogue to digital information. Selection processes shape the evolution of information ecosystems in which conventions are established for the ways in which information is used. The conventions determine norms for information friction and information quality as well as the sources of information and channels used. Digital information reduces information friction, often dramatically, and changes information quality. The increasing use of analytics in business increasingly delivers predictive or prescriptive digital information. These changes are happening faster than information ecosystem conventions can change.

    User acceptance of information technology has been a significant area of research for more than two decades in the field of information technology. This study assessed the acceptance of information technology in the context of Health Information Management (HIM) by utilizing Technology Acceptance Model (TAM) which was modified and applied to assess user acceptance of health information technology as well as viability of TAM as a research construct in the context of HIM. This was a descriptive- analytical study in which a sample of 187 personnel from a population of 363 personnel, working in medical records departments of hospitals affiliated to Tehran University of Medical Sciences, was selected. Users' perception of applying information technology was studied by a researcher-developed questionnaire. Collected data were analyzed by SPSS software (version16) using descriptive statistics and regression analysis. The results suggest that TAM is a useful construct to assess user acceptance of information technology in the context of HIM. The findings also evidenced the perceived ease of use (PEOU) and perceived usefulness (PE) were positively associated with favorable users' attitudes towards HIM. PU was relatively more associated (r= 0.22, p = 0.05) than PEOU (r = 0.014, p = 0.05) with favorable user attitudes towards HIM. Users' perception of usefulness and ease of use are important determinants providing the incentive for users to accept information technologies when the application of a successful HIM system is attempted. The findings of the present study suggest that user acceptance is a key element and should subsequently be the major concern of health organizations and health policy makers.

    In this work, the remove a dye from aqueous solution and the treatment of textile wastewater using natural and iron and copper modified materials and advanced oxidation by Fenton and photo-Fenton heterogeneous processes are presented. Clay and activated carbon were modified using Fe and Cu electrodes at ph values of 7 and 2 respectively. The materials were characterized by scanning electronic microscopy (Sem), electron X-ray dispersive spectroscopy (EDS), X-ray diffraction and specific area (Bet), the optimum ph for clay modifications with Fe and Cu was 7, whereas for copper modified activated carbon was 2, because de elemental analysis indicated that under the above conditions the content of evaluated metals is highest. The specific area for natural and iron and copper modified clay samples was 5.97, 131.30 and 78.44 m{sup 2}/g, whereas for natural and copper modified activated carbon at ph 2 was 654.85 and 647.61 m{sup 2}/g. Dye and wastewater used in this study were obtained from a laundry where jeans are manufactured in Almoloya del Rio in Mexico State. Dye was characterized by infrared spectrophotometry and UV-Vis and it was compared with a standard of potassium indigo trisulfonate and it was observed that both spectra were identical, whereby the dye used in this study is an indigo dye with a maximum absorption band at 591 nm. The characterization of wastewater shows a low biodegradability index (0.25) indicating the presence of non-biodegradability organic matter, and a high concentration of phosphorous was found (93.7 mg/L). A compound parabolic concentrator (CPC-2D) was built to concentrate UV radiation from sunlight and applied in photo-Fenton heterogeneous process obtaining concentrated UV-A and UV-B radiation of 54.29±0.71 and 1.65±0.37 W/m{sup 2} respectively. Iron modified clay (Mt-Fe-7) and copper modified activated carbon (Ac-Cu-2) was used as catalyst in the photo-Fenton process with hydrogen peroxide. The results show that using 1.5 g of catalyst, a concentration of H{sub 2}O{sub 2} of 0.5 M and UV radiation, Ac-Cu-2 promoted the oxidation of dye present in aqueous solutions in 2 h, whereas for Mt-Fe-7 the oxidation was achieved in 3.5 h with removal efficiencies of 99 and 98%. The removal efficiencies for color from textile wastewater was of 93% and 90% for Ac-Cu-2 and Mt-Fe-7 respectively in 4 h of treatment. (Author)

    In this article is presented a solar refrigeration system that integrates the more recent and important technological advances of the training solar systems (SCS) and of the advanced absorption units. An analysis and evaluation is made of the energy behavior of the absorption system with heat exchanger absorber-generator (GAX), air cooled and assisted by a hybrid power plant natural gas-solar. Given the characteristic of high not-linearity of the resulting system of occupations, the proposed methodology contemplates a calculation sequence for the external currents and an iterative procedure for the internal currents. The unit was designed with a capacity of 10.6 kw (3 tons.) of cooling and uses ammonia-water as working fluid. Giving priority to internal energy integration, an arrangement of the GAX cycle is proposed, that allows 19% of solar contribution at full load, being able to be greater at partial loads. In spite of using as cooling means air at 40 Celsius degrees with a relative humidity of 24%, a COP of 0.86 in the cooling mode was obtained and 1.86 in the heating mode, with an internal energy integration of 1013 kJ/min, 37% more of the energy that is supplied in the generator. The massic flow rates of the GAX cycle were compared with those of a basic cycle, resulting 73% and 62% lower for the circulation rate and for the flow rate, respectively. [Spanish] En este articulo se presenta un sistema de refrigeracion solar que integra los avances tecnologicos mas recientes e importantes de los sistemas de capacitacion solar (SCS) y de las unidades de absorcion avanzadas. Se realiza un analisis y evaluacion del comportamiento energetico del sistema de absorcion con intercambio de calor absorbedor-generador (GAX), enfriado por aire y asistido por una fuente de energia hibrida gas natural-solar. Dada la caracteristica de alta no-linealidad del sistema de ocupaciones resultante, la metodologia propuesta contempla una secuencia de calculo para las corrientes externas y un procedimiento iterativo para las corrientes internas. La unidad fue disenada con una capacidad de 10.6 kW (3 Ton.) de enfriamiento y utiliza como fluido de trabajo amoniaco-agua. Dando prioridad a la integracion energetica interna, se propone un arreglo del ciclo GAX que permite el 19% de aportacion solar a plena carga, pudiendo ser mayor a cargas parciales. A pesar de utilizar como medio de enfriamiento aire a 40 grados Celsius con una humedad relativa de 24%, se obtuvo un COP de 0.86 en modo de enfriamiento y 1.86 en calentamiento, con una integracion energetica interna de 1013 kJ/min, el 37% mas de la energia que se suministra en el generador. Las relaciones de flujo masico del ciclo GAX fueron comparadas con las de un ciclo basico, resultando 73% y 62% menos para la relacion de circulacion y relacion de flujo respectivamente.

    Full Text Available Compuestos alternativos en el sector de la envolvente se obtienen por extrusión de estirado de secciones y perfiles de panel de enclavamiento estrechas. Estos elementos estructurales, resistentes al impacto, tienen la ventaja de una instalación más rápida y segura, y su diseño modular les hace idóneos para muchos edificios y otras aplicaciones. Un desarrollo adicional en esta área puede ser la obtención de una alternativa sostenible a los perfiles compuestos actuales. Estudios anteriores han demostrado que los compuestos fabricados a partir de materiales naturales tales como fibras y polímeros bio-derivados, ofrecen una alternativa sostenible a los polímeros y materiales compuestos tradicionales. El objetivo de este desarrollo es reemplazar el típico perfil de acero ligero. Los perfiles de acabado también se pueden utilizar para terminar tabiques de mampostería existentes, revestimiento de ejes mecánicos y de extracción y revestimiento de la columna. Los perfiles se han diseñado utilizando bio-polímeros, reforzados con fibras naturales. Se han establecido los parámetros de procesamiento y las formulaciones apropiadas de bioresina y fibras naturales. También se ha evaluado la adaptación de las técnicas de procesamiento de pultrusión existentes a las características concretas de los nuevos biomateriales y fibras naturales. Como resultado, los perfiles de pultrusión adaptados a la construcción se han desarrollado con la incorporación de nuevos materiales y biomateriales basados en resina. Abstract An alternative composites answer in the envelope sector is the fabrication by pultrusion of narrow interlocking panel sections and profiles. These impact-resistant structural elements have the advantage of quicker, safer installation and their modular design equally answers many identical building and other applications¡Error! No se encuentra el origen de la referencia.. An additional development in this area can be the obtaining of a sustainable alternative to current composite profiles. Previous studies have shown that biocomposites manufactured from natural materials such as fibres and bio-derived polymers; offer a sustainable alternative to traditional polymers and composites. The goal of this development is to replace the typical light gauge steel profile with a state of the art bio-composite integrated system. The finish profiles can also be used to finish existing masonry partition walls, cladding mechanical and extraction shafts and column cladding. The profiles have been designed using bio-polymers, reinforced with natural fibres where possible and necessary. Proper formulations of the bioresin, natural fibres and processing parameters have been established. The adaptation of the existing processing pultrusion techniques to the specific characteristics of the new biomaterials and natural fibres has been also assessed. As a result, demonstrators of pultrusion profiles adapted to building envelopes have been carried out incorporating novel materials and bio based resin.

    Full Text Available During a nine month field study, we assess the ability of spider (Ateles geoffroyi and howler (Alouatta pigra monkeys to cross a large Mesoamerican river, and if this behavior is related to deforestation and/or human population size on the disturbed riverbank. The study was conducted along the Lacantún River, southern Mexico, which .divides the Montes Azules Biosphere Reserve and the Marqués de Comillas disturbed region. We collected data on river crossings by both monkey species from 428 hours of surveys along the river and 58 questionnaires completed by knowledgeable local informants. Furthermore, we determined the frequency of river crossing by the two species, location and direction of river-crossing, bank-to-bank river width at the location of reported sighting, and the relationship with deforestation rates and/or human population size in the Marqués de Comillas region. We observed on two separate occasions spider monkeys crossing the river from the disturbed area to the reserve, but howler monkeys were never observed crossing. Interviews suggest, however, that howler monkeys cross the river more frequently than spider monkeys (13 versus 8 reports, respectively. We found that bank-to-bank river width was smaller at river crossing locations in each study site than along the river in general. Furthermore, we found no relationship between river crossings and some human pressures such as deforestation and population size in the region. Whatever the underlying pressures that drive river-crossing events in these two primate species in this region, they appear to be sufficiently strong to stimulate this behavior to occur from time to time.Durante nueve meses evaluamos si los monos araña (Ateles geoffroyi y los monos aulladores (Alouatta pigra tenían la capacidad para cruzar uno de los ríos más grandes de México, y si este comportamiento estaba relacionado con la deforestación y/o el tamaño de las poblaciones humanas en la margen alterada

    This paper investigates the determinants of informal economic activity. We present two equilibrium models of informality and test their implications using a survey of 48,000+ small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer other limitations. In the first model there is a single industry and informal firms face a higher cost of capital and a limitation on size. As a result informal firms are smaller and have a lower capi...

    Full Text Available In view of the high circulation of migratory birds and the environmental and climatic conditions which favor the proliferation of arthropods, the Brazilian Pantanal is susceptible to circulation of arboviruses. However, the amount of data concerning arbovirus vectors in this area is scarce; therefore the aim of this study was to conduct a preliminary investigation of Culicidae species in the Nhecolândia Sub-region of South Pantanal, Brazil and their potential importance in the arbovirus transmission. A total of 3684 specimens of mosquitoes were captured, 1689 of which caught in the rainy season of 2007, were divided into 78 pools and submitted to viral isolation, Semi-Nested RT-PCR and Nested RT-PCR, with a view to identifying the most important arboviruses in Brazil. Simultaneously, 70 specimens of ticks found blood-feeding on horses were also submitted to the same virological assays. No virus was isolated and viral nucleic-acid detection by RT-PCR was also negative. Nevertheless, a total of 22 Culicidae species were identified, ten of which had previously been reported as vectors of important arboviruses. The diversity of species found blood-feeding on human and horse hosts together with the arboviruses circulation previously reported suggest that the Nhecolândia Sub-region of South Pantanal is an important area for arbovirus surveillance in Brazil.Regiões como o Pantanal brasileiro, que apresentam fatores como riqueza de fauna silvestre incluindo circulação de aves migratórias e condições ambientais e climáticas favoráveis à proliferação de artrópodes estão potencialmente sujeitas à circulação de arbovírus. Entretanto, poucos trabalhos foram realizados acerca da presença de arbovírus em potenciais vetores no Pantanal. Neste sentido o principal objetivo deste trabalho foi conduzir uma investigação preliminar para presença de arbovírus em amostragens de culicídeos capturados na Sub-região da Nhecolândia no Pantanal

    Full Text Available Recently, the methods of quantum theory (QT, especially quantum information and probability, started to be widely applied outside of physics: in cognitive, social and political sciences, psychology, economics, finances, decision making, molecular biology and genetics. Such models can be called quantum-like, in contrast to real quantum physical cognitive and biological models. Quantum-like means that only the information and probability structures of QT are explored. This approach matches the information interpretation of QT well (e.g., Zeilinger and Brukner, Fuchs and Mermin, D’Ariano, as well as the informational viewpoint on physics in general (e.g., Wheeler’s “it from bit” paradigm. In this paper, we propose a quantum-like model of an information laser by precessing the assumptions on the structure of state spaces of information processors, “information atoms” (i-atoms and information fields. The basic assumption is the discrete structure of state spaces related to quantization of an information analog of energy. To analyze a possible structure of the state space of i-atoms leading to the possibility to create information lasers, we have to develop a purely information version of quantum thermodynamics. We did this by placing the main attention on the derivation of the conditions for the equilibrium of information exchange between i-atoms and a quantized information field.

    Full Text Available En el momento de hacer el diagnóstico de los tumores malignos que ocasionan obstrucción del esófago, la vía biliar y el tracto urinario, la mayoría de los pacientes no tiene otras opciones terapéuticas excepto los cuidados paliativos. La presencia de síntomas molestos e incapacitantes, así como la amenaza a la existencia y el miedo a la muerte comprometen la calidad de vida. En este trabajo se realizaron a 25 pacientes procedimientos intervencionistas radiológicos como fueron: prótesis metálicas autoexpandibles en el esófago y en la vía biliar y nefrostomía percutánea. Se evaluaron, antes del procedimiento y a los 1, 3 y 6 meses la evolución de los síntomas clínicos, los criterios paraclínicos, las complicaciones de los procedimientos, el dolor por medio de la escala análoga visual y la calidad de vida por medio del cuestionario SF36. En los 8 pacientes con cáncer del esófago mejoraron el dolor y la disfagia y se mantuvieron el índice de masa corporal y la calidad de vida. En los 11 con obstrucción urinaria mejoraron el nitrógeno ureico, la creatinina y la calidad de vida al primer mes y al tercero. En los 6 que tenían obstrucción maligna de la vía biliar mejoraron los niveles de bilirrubina, el prurito, las náuseas y la calidad de vida al mes, con estabilidad del estado nutricional.

Metodología: el protocolo experimental se realizó en banda rodante, luego de nueve minutos de calentamiento, a una velocidad equivalente al 50% de la FCR y con una pendiente del 1%; siguieron 88 minutos de carrera, en tres intervalos, los dos iniciales de 29 minutos y el último de 30; la pendiente se mantuvo y la velocidad se incrementó al 80% de la FCR; finalmente, 90 minutos de recuperación, en tres intervalos de 30 minutos cada uno. No se hizo reposición hídrica durante el tratamiento deshidratado (DH; durante los tratamientos con hidratación se empleó un volumen similar de tres bebidas de diferente osmolaridad (H-I, H-II, H-III, el cual fue ingerido ad libitum. Resultados: durante la etapa de ejercicio la pérdida hídrica fue de 1.440 ml/h mientras que el volumen ingerido fue de 407 ml/h. Se observó, en cada uno de los tratamientos, una pérdida porcentual del PC (p<0,001; un incremento de la FC (p<0,05, y excepto con H-II y H-III una reducción porcentual del VP (p<0,05. No hubo diferencias intertratamientos en el porcentaje de la pérdida del PC, en el aumento de la FC ni en la reducción porcentual del VP. Conclusiones: la ingesta ad libitum fue menor que la cantidad recomendada internacionalmente por lo que, probablemente, no se pudieron establecer los efectos de la osmolaridad de las bebidas hidratantes sobre las variables estudiadas. Estos hallazgos nos obligan a revisar las prácticas de hidratación de nuestros deportistas ya que, al parecer, no ingieren la cantidad adecuada de líquidos para obtener los beneficios atribuidos a la hidratación. Objetive: to determine the amount of ad libitum intake of three rehydrating beverages of different osmolalities, and to establish their effects on the percentage of body weight loss, the increase of heart rate and the reduction of plasma volume, in nine subjects with aerobic training, during a highintensity,long-duration run. Methodology : the experiment was carried out on a treadmill with 1% of inclination that was kept constant throughout the procedure; it started with 9 minutes of warm-up at a speed equivalent to 59% of the reserve heart rate; then, 88 minutes of running divided in three intervals (29, 29, and 30 minutes at 80% of the reserve heart rate; finally, 90 minutes of recovery in three intervals of 30 minutes each. During the “dehydrated treatment” no fluid replacement was done; during the “Hydrating treatments” (H-I, H-II, H-III equivalent volumes were drunk of the aforementioned rehydrating beverages. Results: during the exercise period the fluid loss was 1.440 ml/h. In each one of the treatments there was a loss of body weight (p<0.001, an increase of heart rate (<0.05 and, except for HII and H-III, a reduction of plasma volume (p<0.05. There were no differences between the treatments in these three parameters. Conclusions: ad libitum intake was less than the amount internationally recommended; probably that explains that the effects of osmolality of the rehydrating beverages on the analyzed parameters could not be determined. These findings ought to motivate a review of the hydrating practices of our athletes because, seemingly, they are not ingesting an adequate amount of fluids to obtain the benefits attributed to hydration.

    CERN Document Server

    Fortin, Sebastian; Holik, Federico; López, Cristian

    2017-01-01

    Combining physics and philosophy, this is a uniquely interdisciplinary examination of quantum information science which provides an up-to-date examination of developments in this field. The authors provide coherent definitions and theories of information, taking clearly defined approaches to considering information in connection with quantum mechanics, probability, and correlations. Concepts addressed include entanglement of quantum states, the relation of quantum correlations to quantum information, and the meaning of the informational approach for the foundations of quantum mechanics. Furthermore, the mathematical concept of information in the communicational context, and the notion of pragmatic information are considered. Suitable as both a discussion of the conceptual and philosophical problems of this field and a comprehensive stand-alone introduction, this book will benefit both experienced and new researchers in quantum information and the philosophy of physics.

    This document is the second of a planned four-volume work that comprehensively discusses the security classification of information. The main focus of Volume 2 is on the principles for classification of information. Included herein are descriptions of the two major types of information that governments classify for national security reasons (subjective and objective information), guidance to use when determining whether information under consideration for classification is controlled by the government (a necessary requirement for classification to be effective), information disclosure risks and benefits (the benefits and costs of classification), standards to use when balancing information disclosure risks and benefits, guidance for assigning classification levels (Top Secret, Secret, or Confidential) to classified information, guidance for determining how long information should be classified (classification duration), classification of associations of information, classification of compilations of information, and principles for declassifying and downgrading information. Rules or principles of certain areas of our legal system (e.g., trade secret law) are sometimes mentioned to .provide added support to some of those classification principles.

The recovery between 77.5-112%, linearity between 0.01 mg kg-l - 2 mg kg-l with correlation factors R2 higher than 0.99 and LOQ between 0.2 µg kg-1- 6.25 µg kg-l were found. Some samples were contaminated with parathion-methyl, a highly carcinogenic organophosphorous insecticide, even though these pesticides had already been banned. For the first time, this study provides information about soil contamination levels due to pesticides in Central Nepal and shows that further research and information campaigns for farmers are necessary.El uso creciente de pesticidas para la producción agrícola está ocasionando problemas de contaminación de suelos en diferentes partes de Nepal. Los suelos agrícolas no contaminados son de gran importancia puesto que tienen un impacto directo sobre la seguridad alimentaria y la salud humana. El objetivo de este estudio fue investigar la calidad y cantidad de pesticidas en muestras de suelo de distintos distritos cercanos a la capital de Nepal, Katmandú, que abastecen de fruta y verdura a esta ciudad. Se llevó a cabo un cuestionario en cuatro distritos de los alrededores de Katmandú para evaluar los tipos de pesticidas de uso más común en ellos. Se tomaron 15 muestras de suelo a una profundidad de 10 cm y se muestrearon cuatro perfiles de suelos a tres profundidades distintas (10, 30 y 50 cm en las granjas de las personas encuestadas. Se tomaron cuatro réplicas de cada muestra de suelo, analizando pH, textura y contenido en carbono orgánico. Para el análisis de las muestras de suelos se utilizó una modificación del método QuEChERS aplicado a alimentos y la caracterización y cuantificación de los residuos de pesticidas en suelos se llevó a cabo por HPLC-MS/MS. El cuestionario realizado reveló que los pesticidas más comunes utilizados en el área de estudio eran carbendazim, chlorpyrifos-methyl, parathion-methyl, imidacloprid, metalaxyl, dimethoate, omethoate y dichlorvos.

Based on the fact that the state variable evolution equation of respective dynamic systems, i.e. Fokker-Planck equation and Liouville diffusion equation can be regarded as their information symbol evolution equation, we derived the nonlinear evolution equations of Shannon dynamic entropy density and dynamic information density and the nonlinear evolution equations of Boltzmann dynamic entropy density and dynamic information density, that describe respectively the evolution law of dynamic entropy and dynamic information. The evolution equations of these two kinds of dynamic entropies and dynamic informations show in unison that the time rate of change of dynamic entropy densities is caused by their drift, diffusion and production in state variable space inside the systems and coordinate space in the transmission processes; and that the time rate of change of dynamic information densities originates from their drift, diffusion and dissipation in state variable space inside the systems and coordinate space in the transmission processes. Entropy and information have been combined with the state and its law of motion of the systems. Furthermore we presented the formulas of two kinds of entropy production rates and information dissipation rates, the expressions of two kinds of drift information flows and diffusion information flows. We proved that two kinds of information dissipation rates (or the decrease rates of the total information) were equal to their corresponding entropy production rates (or the increase rates of the total entropy) in the same dynamic system. We obtained the formulas of two kinds of dynamic mutual informations and dynamic channel

    We are often told that we are ""living in an information society"" or that we are ""information workers."" But what exactly do these claims mean, and how might they be verified? In this important methodological study, Alistair S. Duff cuts through the rhetoric to get to the bottom of the ""information society thesis."" Wide-ranging in coverage, this study will be of interest to scholars in information science, communication and media studies and social theory. It is a key text for the newly-unified specialism of information society studies, and an indispensable guide to the future of this disc

    2017-03-01

    Full Text Available This article briefly discusses various definitions and concepts of the so-called information society. The term information society has been proposed to refer to the post-industrial society in which information plays a pivotal role. The definitions that have been proposed over the years highlight five underlying characterisations of an information society: technological, economic, sociological, spatial, and cultural. This article discusses those characteristics. While the emergence of an information society may be just a figment of one’s imagination, the concept could be a good organising principle to describe and analyse the changes of the past 50 years and of the future in the 21st century.

  7. Nuclear Information Democratization

    International Nuclear Information System (INIS)

    Savić, Dobrica

    2013-01-01

    Nuclear information (Nl) interests people for many reasons, with energy supply, safety, and security being at the top of the list. Democratizing nuclear information has its roots in the growth of a knowledge-based economy, the knowledge worker as a user of nuclear information, developments in information and communication technologies (ICT), and the impact of internet growth. Results of democratization are apparent in the process of information creation, in how nuclear information is distributed and accessed, and in the conditions for using the information found. The International Nuclear Information System (INIS) both reflects and contributes to these trends. Nuclear information falls under the overall umbrella of scientific and technical information (STI). It is highly specialized, but it follows general principles and trends of STI. The world of STI has its own culture and its own long-established rules of use and existence. These have brought us many inventions and improvements, introduced important technological changes, and made our lives and work much easier and more pleasurable. However, the world is constantly changing, and the traditional closed STI environment, including the world of nuclear information, is not keeping up with today’s changes. (author)

  8. Informed Consent in Dentistry.

    A review of literature regarding informed consent in dentistry reveals a paucity of information and minimal scholarship devoted to this subject. But this begs the question about informed consent somehow being different for dentistry than for medicine or other healthcare delivery. My account draws distinctions where appropriate but is rooted in the premise that informed consent is an ethical construct applicable to vulnerable people as patients independent of what type of treatment or body part being considered. This paper highlights the crucial importance of the process of informed consent and refusal in dentistry, underscoring its important place in oral healthcare. This paper will not address the unique circumstances involving consent in those without capacity or focus on informed consent in the research setting; our focus will be on those patients with full decisionmaking capacity in the clinical setting. I will emphasize the importance of disclosure of treatment options and highlight the benefits of shared-decision-making in the informed consent process.

    General Design Criterion (GDC) 2 to 10 CFR 50 requires that 'structures, systems, and components that are important to safety shall be designed to withstand the effects of natural phenomena, such as tornadoes, without loss of capability to perform their safety functions'. According to Regulatory Guide 1.76, the design-basis intensity of a tornado for a nuclear power plant shall not exceed the intensity of the strongest tornado that occurs with the frequency of 10-7/years. Reinforcing the plant to achieve this goal represents a high increase in the costs of the project, and correspondently increase in the time required to have it commissioned. This way, the right definition of tornado risk in a site would represent savings in money for the project and in time for the licensing of a nuclear power plants. This works aims to establish a preliminary calculation of the tornado risk in the site of Ipero, where will work LABGENE from Brazilian Navy, and RMB from CNEN. (author)

    Full Text Available Based on our research, ethnographic field's work on Bolivian and Peruvian migration in Córdoba, Argentina, we propose to dwell on the analysis of selfreflexivity as researchers. We understand self-reflexivity as all necessary investigative process. Considering our positions (a migrant and a migrant’s daughter studying migrations, we understand that our mere presence in the areas we decided to investigate is a definition itself (Guber, 2014. First, we work on our box of analytical tools; later, we discuss our own experiences as researchers, as a migrant, and as a migrant’s daughter. Finally, we bring some findings and conclusions that highlight the impossibility, and therefore, the need to transcend the dualism between the subject that investigates and the investigated object. This, without denying the differences and inequalities between scientists and study groups as well as the constant tension between bets, dispositions, and intentions that exceed the scientific field.
