EL BANANO VERDE DE RECHAZO EN LA PRODUCCIÓN DE ALCOHOL CARBURANTE

Directory of Open Access Journals (Sweden)

Angélica María Afanador

Full Text Available Se describe el estado del conocimiento sobre la producción de alcohol anhidro a partir de banano de rechazo mediante un análisis comparativo de los estudios sobre el aprovechamiento de esta fruta en el Urabá antioqueño desde la década de 1980 hasta la actualidad. Contempla su disponibilidad como materia prima, su composición química, los procesos fisicoquímicos de transformación del banano en alcohol anhidro y los impactos ambientales potenciales de esta industria. Si bien es enorme el volumen de banano de rechazo, existe incertidumbre sobre su disponibilidad para la industria del alcohol, ya que se emplea en la producción de abonos y la alimentación animal. No obstante los avances y posibilidades de perfeccionar el proceso tradicional de producción de alcohol anhidro (hidrólisis ácida o enzimática y fermentación alcohólica, la fermentación ABE se perfila como un proceso industrial en el futuro cercano, apoyado en tecnologías de deshidratación como la pervaporación y bioadsorción. A la fecha no se conocen estudios de impacto ambiental de la producción de etanol a base de banano verde.

Full Text Available A partir de la teoría del agua rígida y de los trabajos desarrollados por Wenninger se alcanzó una concepción más clara sobre los mecanismos de aglutinación en verde de las mezclas de moldeo. Al mismo tiempo, se presta una particular atención a los ensayos de compactibilidad, resistencia a la compresión en verde y humedad, como índices más representativos de dicho proceso de aglutinación. Se demuestra la relación que existe entre estos ensayos y las consecuencias de los trabajos de Wenninger. Se hace particular énfasis en el ensayo de compactibilidad por considerarlo de aplicación limitada.

Full Text Available El uso de abonos verdes es una práctica que, potencialmente, puede ofrecer además de beneficios indirectos como conservación de suelos, así como su humedad e incremento de los microorganismos presentes en él, otros beneficios directos como el aporte de materia orgánica y nutrimentos al suelo. Sin embargo, los agricultores muchas veces omiten
esta práctica por la aparente escasez de fuentes de abono verde en sus fincas, ignorando que algunas especies arbóreas, presentes en sus fincas o en las de sus vecinos, pueden constituirse en las fuentes buscadas. En otro caso, si el agricultor está usando abonos verdes, la mayoría de las veces, ignora si el material usado es capaz de descomponerse y liberar los nutrimentos en el lapso que corresponde al desarrollo del cultivo. En este sentido, lo ideal sería conocer tanto la curva de nutrientes requeridos por el
cultivo, como la curva de liberación de los mismos a través del tiempo, a fin de ajustar las dos en el campo para lograr la máxima eficiencia. En las dos situaciones planteadas, es importante disponer de un indicador que permita elegir una
fuente de abono verde en el momento de su aplicación. Hasta ahora, esto se puede lograr a través de estudios exhaustivos de la dinámica de descomposición. Sin embargo, estos estudios son complejos y costosos en dinero y tiempo, por lo
tanto inaccesibles para el agricultor. En este trabajo se evalúan los indicadores más importantes, reportados por la literatura, a través del proceso de descomposición y liberación de nutrimentos del follaje de ocho especies de interés agroforestal en la franja premontano de Colombia
y se concluye que, para este grupo de especies, la relación ligninalnitrógeno inicial del follaje resultó ser el indicador más robusto, permitiendo predecir la velocidad de descomposición.Using green manure potentially can offer indirect benefits, like soil soil conservation and improvement of soil

Full Text Available La riqueza de un Abono Orgánico Fermentado, se determina por la población de microorganismos allí presentes, éstos dependen de la temperatura, el pH, la humedad, el oxígeno y alimento principalmente. Dichas condiciones cambian entre un biol, bocashi y el suelo; pues en éste las poblaciones que se encuentran no son las mismas de los AOF. En consecuencia el aporte de tales abonos es alimento para las plantas a partir de los minerales agregados en forma de sulfatos, fosfatos, carbonatos y de la mineralización-humificación de la materia orgánica. También es nutriente para los microorganismos que utilizan estos minerales y las moléculas orgánicas. El porcentaje de materia orgánica se convierte en: fuente de alimento para los actinomicetos, carbono para fijadores de nitrógeno de vida libre, fosfatos inorgánicos para solubilizadores de este compuesto y demás organismos presentes en el medio.

Full Text Available En mayor proporción que en otros granos básicos, los rendimientos en el cultivo del arroz dependen de la eficiencia en la fertilización nitrogenada. Para evaluar la respuesta del cultivo en los sistemas de siembra directa sobre rastrojos “SDR” y labranza mecanizada convencional “LMC” a diferentes alternativas de fertilización nitrogenada, se realizó una evaluación financiera durante un plazo de 5 años, con 2 ciclos de siembra anuales. El estudio fue realizado de acuerdo a las condiciones agronómicas y económicas de agroecosistemas arroceros inundados en la Región Pacífico Norte de Costa Rica. De las alternativas evaluadas, la fertilización nitrogenada con 3 fraccionamientos y el uso de mucuna (Mucuna deeringiana como abono verde entre ciclos del cultivo fue la más rentable, con un valor actualizado neto “VAN” y un valor esperado de la tierra “VET” de 3031 y 33346 US.$ ha-1, respectivamente. La interacción entre el sistema SDR, el uso de mucuna como abono verde, y la fertilización nitrogenada dividida en 3 aplicaciones permitió mayores rendimientos y mayor rentabilidad con respecto a las otras alternativas evaluadas.

Full Text Available En Paraguay el cultivo de sésamo (Sesamum indicum L. es cada vez menos productivo debido a la degradación de la fertilidad de los suelos. La fertilización nitrogenada eleva los rendimientos en suelos pobres en este nutriente, pero su eficiencia aún no es bien conocida. En el estudio se utilizó la técnica isotópica para determinar el destino del N aplicado a un cultivo de sésamo. En el campo experimental de la Facultad de Ciencias Agrarias de la Universidad Nacional de Asunción, Paraguay, en un diseño experimental de bloques completos al azar se estudió la eficiencia en la aplicación de N como fertilizante y abono verde (lupino + avena negra con y sin laboreo del suelo. El N fue aplicado como urea-15N (5% enriquecimiento a razón de 50 kg/ha. Los resultados mostraron contenidos (kg/ha de N en granos (84, materia seca (104 y suelo hasta 15 cm (938. El 20% del N aplicado fue absorbido por la planta, 42% permaneció en el suelo y 38% no pudo contabilizarse y posiblemente se perdió por lixiviación y volatilización. La técnica de dilución isotópica fue útil para determinar el destino del N aplicado, pero sobreestimó el aporte de los abonos verdes en el contenido de N en el suelo.

Full Text Available Introducción: Los impactos del calentamiento global y el cambio climático son una preocupación en prácticamente todos los sectores de la sociedad, debido a las consecuencias que ya se perciben y que afectarán cada día más tanto a los sistemas naturales como a los creados por el hombre, generalmente de forma negativa. Para revertir estos efectos negativos y no continuar deteriorando el medio ambiente, es necesario un tipo especial de personas que sean capaces de tomar las decisiones adecuadas en los ámbitos en los que se desenvuelven. En esta investigación, estos seres humanos se denominan: “personas con talento verde”. El término talento verde no ha sido caracterizado y su uso es aun restringido. Esta investigación hace una caracterización del talento verde y propone una encuesta para detectar a las personas que cuentan con estas características. En este artículo, se reporta solo la validación de la encuesta. Es importante hacer notar que este trabajo forma parte de una investigación más amplia que busca conocer la relación entre directivos con talento verde y prácticas de cadena de suministro sustentable. Método: La caracterización del talento verde se realizó a través de la metodología de representaciones sociales, de la cual surgieron una serie de preguntas que buscan las características de talento verde en directivos de empresas y que forman parte de una encuesta de mayor cobertura que fue piloteada para su validación. La confiabilidad se midió a través del Alfa de Crombach y la validez por un Análisis Factorial. Resultados: Se encontraron nueve aspectos que caracterizan a las personas con talento verde, con las cuales se construyeron también nueve preguntas. Estas preguntas se hicieron a 25 directivos de empresas que participan en la Cámara de la Industria de la Transformación (CANACINTRA con el objetivo de validar el instrumento. El alfa de Crombrach obtenido fue del 0.948 y el análisis factorial indica

Full Text Available En la región Andino-patagónica frecuentemente la reposición de nutrientes para diferentes cultivos se lleva a cabo mediante el uso de estiércoles mezclados con viruta, comúnmente denominados abonos. Los mismos son acumulados en pilas de 1,5-2 m de altura. Al permanecer durante un período de tiempo al aire libre puede producirse un compostaje parcial, lo cual sería beneficioso. El compostaje es un proceso biooxidativo que involucra un sustrato orgánico, una etapa termofílica que debe alcanzar los 55 °C y una etapa de maduración. Si los abonos permanecen a la intemperie los nutrientes pueden ser transportados por el agua de percolación (particularmente en los meses de invierno de mayor precipitación, perdiéndose del suelo.

Full Text Available La vegetación nativa ha cumplido un papel importante a través del tiempo en el desarrollo e identidad de las comunidades. Esta no se limita estrictamente a una función biológica o ecológica en un ecosistema; sino que también interviene en aspectos culturales y sociales de la población humana. A pesar de ello, en la actualidad se ha visto que existe una falta de apropiación por los espacios verdes y un desconocimiento de la función e importancia de las plantas de origen nativo en nuestro entorno. El objeto del presente artículo fue propiciar una conciencia ecológica en los estudiantes de grado octavo del colegio Gimnasio El Portillo del municipio de Cota-Cundinamarca, a partir del reconocimiento de la flora del lugar y la construcción de micro-invernaderos de plantas nativas, lo cual se logró mediante  la implementación de seis actividades guiadas, que permitieron dar cuenta de las concepciones de los estudiantes y construir nuevo conocimiento escolar, al complejizar el concepto que tenían  hacia los espacios verdes y la flora nativa y exótica desde su propio contexto; y generar sentido de apropiación y conservación de los mismos. Concluyéndose que la siembra de plantas nativas en las zonas verdes de su entorno hace que los estudiantes tengan un contacto más cercano con la flora de su país y puedan apropiarse de sus espacios y tomar conciencia de la importancia de sus usos, así como la implicación que tiene su permanencia o desaparición para un ecosistema.

Full Text Available This study evaluated the effect of using the green manure Sesbania rostrata as a preceding crop on the agricultural yield of rice. The rice was cultivated with two levels of mineral fertilizers (50 and 100% of the economical optimum level of N-P-K. Additionally, the contribution to the nitrogen nutrition of rice from the green manure previously incorporated into the soil was studied in pots using 15N stable isotope analysis. The results indicated that the Sesbania rostrata incorporation allowed the paddy rice yield to increase by at least 1 Mg ha-1 and to save 50% of the mineral fertilization employed, during two consecutive harvests. The 15N isotope analysis showed that although the N accumulation by the crop was significantly stimulated, the green manure N did not contribute directly to the growth of the rice plants, at least during their first cycle. Nevertheless, it is expected that in the medium term, the organic N derived from this green manure would restore the soil mineralized N extracted by the rice crop, thereby balancing the N losses in the system and even improving the soil nitrogen fertility.En este trabajo se evalúa el efecto del abono verde Sesbania rostrata como cultivo precedente sobre el rendimiento agrícola del arroz, cultivado con dos dosis de fertilizantes minerales (50 y 100% de la dosis N-P-K óptima económica.

This article shows a non-lineal mathematical model for the condensate, and feed water systems and for feed water heater drains at the Laguna Verde Nuclear Power Station for its simulation in real time. The model allows the calculation of flows and pressures in all the piping system and equipment that integrate the systems. It was obtained by using the force unbalance in the fluid concept and is capable of reproducing its dynamic behavior through variations induced by the different operation modes and more common failures. The final model objective is to form part of the Laguna Verde simulator that will be used for operator training of this Nuclear Power Plant. [Espanol] En este articulo se muestra un modelo matematico no lineal de los sistemas de condensado, agua de alimentacion y drenes de calentadores de la central nuclear de Laguna Verde para su simulacion en tiempo real. El modelo permite calcular los flujos y las presiones en toda la red de tuberias y equipos que integran los sistemas. Se obtuvo utilizando el concepto de desbalance de fuerzas en el fluido, y es capaz de reproducir su comportamiento dinamico ante variaciones inducidas por los diversos modos de operacion y fallas mas comunes. El objetivo final del modelo es formar parte del simulador de Laguna Verde que se empleara para el adiestramiento de los operadores de dicha central nuclear.

results of the environmental measurements also demonstrate that the nuclear option of electrical energy generation, when it is operated with safety and efficiency, is one of the friendlier forms with the environment of power generation. [Spanish] Hace 36 anos nacio uno de los proyectos energeticos mas importantes de Mexico; el diseno y construccion de la Central Nuclear Laguna Verde. Este proyecto se volvio realidad gracias al compromiso de un grupo de profesionistas mexicanos que dieron lo mejor de ellos para su realizacion. En Mexico no existia en ese momento una legislacion que contemplara la proteccion del medio ambiente; sin embargo, la Constitucion preve que cuando en el pais no exista legislacion para el desarrollo de un proyecto. Este debe adoptar la legislacion del pais que lo esta vendiendo. En el caso especifico de Laguna Verde, se adopto la legislacion de los Estados Unidos de America y en la parte ambiental se tuvo que realizar el primer Manifiesto de Impacto Ambiental, que se titulo Informe ambiental para la construccion de la Central Nuclear Laguna Verde en el Estado de Veracruz. Este estudio lo realizaron varias instituciones tanto nacionales como extranjeras. Entre las mas sobresalientes se cuenta con: la Universidad Nacional autonoma de Mexico, el Instituto Politecnico Nacional, la Universidad Veracruzana, el Instituto Nacional para la Investigacion de los Recursos Biologicos, el Instituto de Ecologia, A.C. Con este informe, los ingenieros se dieron a la tarea de disenar y construir, los biologos y ecologos a realizar los estudios para mitigar los efectos causados al medio ambiente durante la construccion y, posteriormente, durante la operacion de la Central Nuclear. Despues de 18 anos de operacion comercial de la central se concluye el presente libro, en el cual se comparan los resultados obtenidos en 1972, cuando se iniciaron los estudios para el informe ambiental, contra los obtenidos a lo largo de este periodo.

Se seleccionó una zona de estudio en el Estado Lara (Venezuela, en el municipio Palavecino, en las inmediaciones de la Quebrada Tabure, considerando los techos verdes desde el punto de vista de reductores de escorrentía. Se elaboró una aplicación llamada “TechosVerdes.py” en el programa de licencia libre Python, con aproximadamente 4600 líneas de código para calcular los hidrogramas de los techos, patios, calles y áreas verdes, basándose en un mosaico creado con imágenes tipo raster en el programa Quantum Gis. La investigación se basó en la comparación directa de trece escenarios hipotéticos, donde se utilizó techos verdes y adicionalmente, tanques de almacenamiento y brocales, con un escenario original en condiciones actuales, sin alteraciones. Se obtuvo como resultado en los hidrogramas calculados para los escenarios hipotéticos, que el caudal pico disminuye, achatándose el hidrograma. This research was carried out using mathematical models in order to compare the runoff from an urban planning with handmade tiles roofs in actual conditions, with one where structures or storage devices and water retention in houses, yards are used, parcels, streets and housing complexes in general. A study area in the state of Lara, Venezuela, in Palavecino municipality, near Quebrada Tabure, was selected and green roofs are considered from the point of view of reducing runoff. An application called "TechosVerdes.py" was made under the license free Python program with approximately 4600 code lines was developed to calculate hydrographs from roofs, patios, streets and green areas

Full Text Available Este trabajo entrega una revisión crítica respecto de la literatura especializada existente acerca de algunas características importantes de los espacios verdes urbanos, como los componentes, funciones, servicios, participación comunitaria, iniciativas y acciones desde una perspectiva eco sistémica. El análisis parte del supuesto de que los espacios verdes urbanos son ecosistemas de vital importancia para mejorar la calidad de vida en un entorno urbano y para proporcionar servicios ecosistémicos, como la biodiversidad y la regulación del clima. Por lo tanto, el espacio verde urbano es un componente esencial de un ecosistema en cualquier desarrollo comunitario. Satisfacer las necesidades de los usuarios está relacionado con las funciones y servicios que los espacios verdes urbanos proporcionan a las comunidades. La participación, el compromiso y el desarrollo de la comunidad requieren mecanismos para asegurar el cumplimiento de las necesidades y aspiraciones de los usuarios locales en la comunidad. Los métodos empleados en este análisis son la revisión de literatura y de documentos secundarios, el análisis de datos existentes acerca de usos y usuarios, y entrevistas con autoridades. Como conclusiones, el documento sugiere iniciativas ambientales, económicas y sociales para las autoridades locales y las comunidades que se pueden aplicar a todas las partes interesadas representadas e involucradas.

Full Text Available El acelerado desarrollo urbano genera una serie de problemas no sólo sociales y económicos, sino también ambientales. Los techos verdes son unas de las nuevas tecnologías que pueden ser utilizadas como herramientas para la gestión ambiental en los edificios. Sin embargo, existen muchas barreras que impiden su implementación a gran escala. Este artículo hace una revisión profunda de las experiencias y resultados de numerosas investigaciones en el tema, destacando los beneficios de los techos verdes y mostrando las barreras para la implementación de esta tecnología en el sector hotelero del Rodadero, Santa Marta. La metodología consistió en la revisión de resultados de investigaciones llevadas a cabo en diferentes ciudades del mundo, haciendo énfasis en las realizadas en condiciones climáticas similares a la zona de estudio. Adicionalmente, se aplicaron encuestas a los gerentes de 18 hoteles en El Rodadero con el fin de conocer su opinión acerca del tema. Como resultado, se concluyó que los techos verdes pueden ser herramientas muy efectivas para la gestión ambiental si son implementados a gran escala. Sin embargo, en el caso de El Rodadero, ésta es una opción poco viable, aunque existe un interés de implementar proyectos pilotos que podrían disipar la desconfianza de los empresarios.

Full Text Available Introdución: El término lavado verde (greenwashing se utiliza para nombrar el modo de comunicación desarrollado por empresarios para tratar de ocultar las verdades que impregnan sus productos y servicios, lo que puede indicar su débil compromiso con el medio ambiente. El objetivo de esa investigación fue el análisis de los atributos gráficos y textuales que figuran en los materiales publicitarios relacionados con comunidades residenciales en el municipio de Caruaru, Pernambuco, los cuales afirmaban tener aspectos "sostenibles". El análisis se ha centrado en entender en qué medida las prácticas de lavado verde podrían ser identificadas en este segmento de mercado. Método: Se realizó un estudio de campo entre enero y marzo de 2012 en los puntos de venta de las propiedades inmobiliarias de aquellos proyectos complementada por el estudio de las campañas de publicidad. Información adicional fue adquirida por conversaciones informales con los intermediarios y otras personas responsables de las acciones de marketing. Complementarmente se verificaron materiales de promoción tales como sitios web, folletos, catálogos, carteles y los stands de comercio. Resultados: Todos los proyectos examinados tenían algún grado de lavado verde en lo que respecta lo establecido en el documento denominado de "seis pecados del lavado verde", y el artículo 36 de la CONAR En cuanto a la infracción de la autenticidad en los medios de publicidad. Conclusión: Caruaru, por su crecimiento exponencial, atrajo empresas atrajo de distintos sectores empresariales. Sin embargo, se insta a repensar como se forman nuevas perspectivas y conceptos de vida y sostenibilidad a partir de desarrollo de acciones reales y transparentes y que cumplan con todos los grupos de interés de la ciudad.

Full Text Available La presente investigación es originada por la necesidad en la ciudad de Sancti Spíritus de un estudio ambiental, que interrelacione cómo ha influido el cambio climático en el clima urbano y la relación de este último con el sistema de áreas verdes de la ciudad, como elemento moderador del ambiente térmico a escala de planeamiento, urbana y arquitectónica, y que a su vez proporcionen elementos más precisos para la toma de decisiones y criterios en las acciones de rehabilitación e inserción que se realicen, o para zonas de nuevo desarrollo dentro de la ciudad. Se analiza el déficit de áreas verdes a nivel de zona tipomorfológica y de consejo popular, además se analizan los problemas del cambio climático, la isla de calor urbana, se definen las variables y parámetros que influyen sobre las condiciones microclimáticas térmicas (Coeficiente de Ocupación del Suelo. Pavimentación, y otros aspectos medioambientales. Posteriormente se realizan mediciones del complejo temperatura – humedad relativa del aire y velocidad del viento en 24 puntos de la ciudad, elaborándose mapas en Sistemas de Información Geográficos (SIG, Mapinfo 6.5 sobre el comportamiento del ambiente térmico y humedad relativa del aire en la ciudad, tema sobre el cual no se ha desarrollado ninguna investigación hasta el momento en la ciudad objeto de estudio y de las cuales es pionera el presente trabajo, aportándose nuevos enfoques y estrategias para estas labores, lo cual incorpora nuevos criterios en el Plan General de Ordenamiento Territorial y Urbano (PGOTU.

Full Text Available Before initiating the building operations for the «Palos Verdes» School, the site was divided into two large horizontal surfaces, at different levels. The lower one served to accommodate the playing fields, a car park, the physical training building, and shop and ancillary buildings. On the higher of these two surfaces, and to the West of the access road, there is a car park and also the building and plot of ground devoted to agricultural technology, as well as the literary studies and general purpose buildings. As a complement to these, there is a series of blocks, arranged in parallel rows, which house the administrative offices, the art school, the craft's school, the general classrooms, and those devoted to higher education. The fascinating aspect of this school is the outstanding penetration of the architect's mind into the essential function of the project. Its most evident merit is the sense of comradeship and harmony that permeates the whole architectural manifold.Antes de construir el complejo escolar «Palos Verdes» se comenzó por crear, en el terreno, dos grandes mesetas a niveles diferentes. Sobre el inferior se organizaron: los campos de juegos, de deportes, un aparcamiento, el edificio para educación física y los destinados a tiendas y servicios. Sobre la meseta superior, al oeste de la vía de acceso, se dispuso un aparcamiento y el edificio y campo para adiestramiento agrícola; al este, otro aparcamiento, el edificio dedicado a materias literarias, y el destinado a usos múltiples. Completan las instalaciones de la escuela una serie de bloques paralelos: la administración, la escuela de arte, las clases de trabajos manuales, las aulas de enseñanzas generales, y las de los cursos superiores. Lo fascinante de este complejo escolar es la perfecta y magistral compenetración del arquitecto con el tema proyectado, y su mayor mérito, la sensación de cordialidad y armonía con el ambiente.

de la periferia de la ciudad, donde coexistían zonas de alto valor ecológico sometidas a agresiones de todo tipo, con otros espacios degradados y marginales, fruto de la expansión urbana e industrial. La restauración ecológico-paisajística de estos espacios y su acondicionamiento para el uso público han permitido configurar un "anillo verde multifunción" en torno a la ciudad que está proporcionando importantes beneficios ambientales, sociales y económicos. El anillo verde ha jugado un papel importante en la integración naturaleza-ciudad, equilibrando la oferta de zonas verdes entre todos los barrios y favoreciendo la conexión entre los espacios verdes urbanos y los espacios naturales del entorno agrícola. Ha propiciado, asimismo, el desarrollo de nuevas actividades relacionadas con el ocio y el esparcimiento y con la formación, educación y sensibilización ambiental; actividades que, por un lado, están suponiendo un revulsivo para el sector empresarial ambiental y la integración socio-laboral de determinados colectivos sociales y, por otro, contribuyen a la conservación de estos espacios, al convertirse los usuarios en sus mayores defensores y guardianes. La utilización de algunos de estos espacios como superficies de laminación de agua en épocas de avenidas para solventar problemas de inundación en las zonas industriales es otro ejemplo del valor añadido obtenido al plantear soluciones integrales. Los excelentes resultados obtenidos tras nueve años de trabajo demuestran la viabilidad técnica y económica y la rentabilidad social de este proyecto, que representa una prueba evidente de la decidida voluntad municipal de avanzar hacia un modelo de ciudad sostenible en armonía con el medio natural que la rodea.

Full Text Available Aunque existe una gran cantidad de trabajos que reportan la fitotoxicidad presente en fertilizantes orgánicos, pocos se han realizado con residuos pecuarios, más específicamente con estiércoles. El presente estudio tuvo por objetivo determinar el índice de germinación (IG como parámetro de fitotoxicidad de dos abonos orgánicos hechos a base de estiércol vacuno, de conejo y un abono comercial. La fitotoxicidad se midió mediante bioensayos de germinación con lechuga, poniendo a germinar diez semillas en 10 mL de extracto acuoso obtenido, respectivamente, de las proporciones 0.5:5.0, 1.0:5.0 y 1.5:5.0 (v:v en relación abono/agua destilada; como testigo se utilizó agua destilada. Tras permanecer seis días en germinación a 25 °C, se recabaron los datos necesarios para calcular el porcentaje de germinación relativo (PGR, crecimiento radicular relativo (CRR y posteriormente obtener el IG. Los resultados arrojaron índices de germinación superiores a 80% en 18 de los 19 tratamientos evaluados; por otro lado, las interacciones entre factores indicaron que es el abono, más que la proporción, lo que determina la posible presencia de fitotoxinas. Los resultados obtenidos permiten afirmar que los abonos evaluados presentan de un moderado a un bajo grado de fitotoxicidad.

Los argumentos higiénicos constituyeron la primera justificación del Parque de la Independencia. El Central Park americano y las discusiones entre Domingo F. Sarmiento y Guillermo Rawson acerca del parque 3 de Febrero de Buenos Aires incidieron en su localización y diseño. Se explican los procesos de ocupación-concesión de las superficies del paseo a corporaciones y asociaciones. Finalmente, se exploran las evidencias de difusión social del Parque, observando el pasaje de un diseño exclusivo, destinado a la distinción social de las elites locales, a otro más pluralizado y orientado a la construcción de un paseo público tendencialmente masivo. El estudio se basa en el relevamiento y la triangulación focalizada de los discursos de la prensa, los vecinos y el municipio.

Full Text Available El emprendimiento verde es entendido en este documento, como el desarrollo de actividades orientadas a la mitigación, reducción o eliminación de problemáticas ambientales, las cuales son consideradas de entrada como innovadoras, en la medida en que proponen cambios en los patro- nes de producción y consumo que deterioran las condiciones naturales del planeta y en el relacio- namiento del ser humano con el entorno. En este caso, el objeto de análisis es el emprendimiento verde orientado a la restauración y conservación del agua y sus espacios en Bogotá y Medellín. La investigación desarrollada se sustentó en la aplicación de entrevistas semi-estructuradas a actores de diferente tipo, involucrados en estas actividades. Se consideró que los espacios del agua son bienes comunes, alrededor de los cuales prevalece el sentir general de que pertenecen a todos y a la vez a nadie. Se concluye que un modelo eficaz para lograr su gestión adecuada implica la co- gestión participativa, lo que abre la posibilidad al emprendimiento verde promulgado por diferen- tes actores. En este sentido, se encontraron emprendimientos promovidos por actores del sector público, empresas privadas, organizaciones sin ánimo de lucro, organizaciones sociales, fondos de agua, entre otros actores; algunos de los cuales intervienen directamente sobre los espacios del agua y otros indirectamente, a través de la optimización del consumo. La intervención en los espacios del agua en Bogotá y Medellín ha generado impactos positivos, no obstante, los esfuerzos aún son muy incipientes y de alcance local, teniendo en cuenta la extensión de los espacios del agua en el territorio.

Full Text Available Finalizando el año 2008 en la ciudad de Medellín, Colombia, ocurrió un deslizamiento de tierra en la urbanización Alto Verde provocando la muerte de doce personas y la destrucción de seis viviendas. Los deslizamientos se destacan por el elevado nivel de deformaciones en una masa de suelo. El presente trabajo utilizó el método del punto material (MPM, método basado en partículas que utiliza una doble discretización Lagrangiano-Euleriana. La doble discretización genera un marco numérico robusto que permite la simulación de grandes distorsiones. El modelo numérico planteó una simplificación de las condiciones geotécnicas, morfológicas y estructurales de las edificaciones envueltas en Alto Verde. El estado de deformación final de la simulación se acomodó satisfactoriamente a las características geométricas finales observadas en campo. Los resultados obtenidos generan aplicaciones como el diseño de barreras, análisis de riesgo o la determinación de la distancia mínima de retiro a una ladera susceptible de deslizamiento.

El estudio permitió comprobar que no existe un desdoblamiento arancelario que facilite la identificación de los tipos de abonos importados desde nuestro país y exportados hacia distintas partes del mundo, ya que el Sistema Armonizado que se utiliza actualmente, no hace una distinción entre los abonos orgánicos animales y los vegetales. Se consideró una Ficha Técnica elaborada como parte de las actividades del Proyecto de Investigación IC-ULVRG-12-l0 "GuÍA PARA EXPORTAR ABONO ORGÁNICO HACIA LOS PRINCIPALES MERCADOS DE ESTADOS UNIDOS, EUROPA Y SUDAMÉRICA" e información sobre Clasificación Arancelaria que se registra en la Organización Mundial de Aduanas OMA. La presente revisión tiene como propósito dar a conocer la importancia del análisis técnico del producto y la interpretación el Sistema Armonizado al momento de asignar una Partida Arancelaria al mismo, especialmente cuando la Codificación Arancelaria de los Productos es la base para facilitar el comercio exterior y elaborar estadísticas del mismo.

Coal, fuel used in thermal power plants for electricity production, contains variable concentrations of naturally occurring radionuclides from natural disintegration series of {sup 2}38U, {sup 2}35U, {sup 2}32Th and also the {sup 4}0K, which are enhanced in the wastes and coproducts due to the industrial process. For this reason, natural radionuclides which are part of the noncombustible fraction of coal, except those volatiles which incorporate directly to the flue gases, concentrates and are partitioned between fly ashes and bottom ashes. This enhancement could cause, to the workers of the installation and to members of the public around the plant, an increase in the exposure which should be assessed under the radiation protection point of view. Present report collect the results obtained from a screening assessment of the radiological impact derived from the normal operation of the Abono coal-fired power plant. The project where this assessment was performed is part of a bigger project which is jointly developed by the Unit of Radiation Protection of the Public and the Environment (UPRPYMA) of CIEMAT and the Environmental Radioactivity Laboratory of the Extremadura University (LARUEX) in agreement with the Spanish Association of the Electrical Industry (ENUSA).

Full Text Available Sustainable Building has grown out of a synthesis of the environmentally-oriented Green Building movement and the broader SD movement. The green movement itself grew out of 1970’s concerns about Energy Conservation, which subsequently morphed into Energy Efficiency, as fuel prices declined during the 1980’s. During the 1980’s, energy issues receded somewhat into the background of general discussion, but concerns arose about the impact that building operations and the production of their constituent materials have on the natural environment. During the same decade, the issue of poor indoor air quality and inadequate ventilation in sealed buildings (“sick building syndrome” became a very public concern. A consensus has gradually evolved concerning the type of issues that should be included within a green type of analysis. Since 2000 the number of environmental assessment methodologies around the world has been increasing rapidly. BREEAM (BRE Environmental Assessment Method was the first system (launched in 1990, to offer an environmental label for buildings. Nevertheless, LEED (Leadership in Energy and Environmental Design has been an incontrovertible success as a tool to promote market transformation. There are a number of different schemes around the world, most of which have been based on GBC and iiSBE (International Initiative for a Sustainable Built Environment. A new assessment method based on impact reduction calculation has been developed. The tool call VERDE is applicable to commercial complexes and residential developments. The methodology are presented and discussed in the paper.

Teniendo en cuenta que estos residuos vegetales, terminan su vida útil en los humedales y no tienen algún uso específico, se generó una alternativa de aprovechamiento de estos residuos, en la producción de compost o abono orgánico. Surge entonces la necesidad de encontrar un método que haga posible su notable reducción, transformación y aprovechamiento de tal manera que se genere un impacto positivo en el ámbito ambiental, económico, social y sanitario. En este caso el compostaje se empleó como técnica para la biodegradación de los residuos vegetales de las especies Buchón de Agua (Eichhornia crassipes, Buchón Cucharita (Limnobium laevigatum. y Junco (Schoenoplectus californicus, transformándolos en un abono orgánico; de igual forma se biodegradaron residuos vegetales de plaza de mercado, que fueron recolectados de la Plaza de mercado de Paloquemao ubicada en la ciudad de Bogotá, empleando la misma técnica con el propósito de tener un punto comparativo en la calidad final de los abonos, con respecto a lo estipulado en la norma NTC 5167 cuarta actualización, referente a parámetros químicos, físicos, microbiológicos con los que deben cumplir los abonos generados a partir de residuos orgánicos de origen animal y vegetal.

Full Text Available La mercantilización e instrumentalización de diversos elementos y procesos naturales ha condicionado perfectas plataformas para la acumulación de riquezas. Esto ha sido posible en la medida que existen las condiciones políticas, sociales y económicas para que suceda. Además, en el caso de las condiciones ambientales urbanas, se suma un "imaginario verde" en un amplio espectro de la población, la cual presenta un gran interés por vivir en espacios dotados de naturaleza. Estas condiciones han determinado que en las ciudades se desarrolle una desigual distribución de las condiciones ambientales, dado que cuando la gestión urbana queda en manos del sector privado, sólo las elites con poder adquisitivo pueden acceder a áreas verdes y al arbolado urbano. La presente investigación busca reconocer a la naturaleza urbana como un "instrumento de consumo" inmobiliario, así como sus implicancias en la distribución de las condiciones ambientales en Santiago de Chile. Para esto se reconoce el espacio urbano en ciudades capitalistas como un eslabón dentro de las plataformas de acumulación de capital. A su vez, se integra la perspectiva de los imaginarios ofertados/empleados por el sector inmobiliario como un tema central para concretar la plataforma de acumulación.

The 665 MWe Laguna Verde-2 nuclear generating unit was accepted into commercial operation on April 10, 1995. The boiling water reactor plant by General Electric (GE) was first synchronized with the grid on November 11, 1994. Laguna Verde-2 is identical with Laguna Verde-1 on the same site. That unit had gone critical for the first time in November 1988 and had first been synchronized with the power grid on April 13, 1989. Commercial operation of Laguna Verde-1 had been started on July 29, 1990. Mexico's only nuclear power plant had been built 70 km north of Veracruz on the east coast and had been scheduled to start operation in 1976. As the Mexican nuclear power program was reduced, the scheduled commissioning dates suffered more and more delays. In the full of 1987, the investigation by the Operational Safety Review Team (Osart) of the International Atomic Energy Agency (IAEA) had indicated that the safety requirements of installations and equpiment were met, and that the whole plant was well prepared for fueling. In mid-1988, the Mexican Government had issued the permit to fuel the Laguna Verde-1 reactor. The contract to build the two units had been awarded in 1972/73. No other nuclear power plants are currently under construction or in the planning phase in Mexico. (orig.) [de

Full Text Available The history of the green fluorescent protein (GFP starts with Osamu Shimomura at the beginning of the 1960s, with his discovery from the extracts of the Aequorea victoria jellyfish. However, it is not until the beginning of the 1990s, that the neurobiologist Martin Chalfie, applying genetic engineering tech- niques, achieved for the first time the heterology expression of the GFP in prokaryotes (E. coli and eukaryotes (Caernohabditis elegans, from a clone of the jellyfish’s gen that codifies the GFP prepared by Douglas Prasher. Besides fluorescing in green, the results from this work also demonstrated that it does not require any other cofactor or enzyme of the jellyfish for its expression or for the own forming of a fluorophore. At the same time, Chalfie proposed that the GFP could be used for the marking of cells on living ani- mals or the tag of proteins. Based upon these results, many scientists started working on research related to the GFP; actually this protein is used on different fields such as biotechnol- ogy, development biology, environmental chemistry and medicine. In the case of the latter, it has helped to elucidate the cellular mechanisms from which diseases are made of. Science owes Roger Tsien, amongst other contributions, the creation of differ- ent mutations of the GFP.La historia de la proteína verde fluorescente (GFP se inicia con Osamu Shimomura a principios de la década de 1960, con su descubrimiento de esta proteína a partir de extractos de la medusa Aequorea victoria.

Full Text Available El color verde de los frutos maduros podría atribuirse a la capacidad de adquirir carbono mediante fotosíntesis, lo cual disminuye los costos reproductivos e incrementa la recompensa nutritiva para los dispersores de semillas. En el muérdago Tristerix corymbosus (Loranthaceae el color de los frutos maduros varía según el bioma: en el matorral chileno los frutos son amarillos mientras que en el bosque templando son verdes. Nuestro objetivo fue determinar si el color de los frutos se relacionaba con la capacidad de ganar carbono vía fotosíntesis y si esta capacidad variaba con la madurez y el bioma. Realizamos mediciones fisiológicas en plantas provenientes de poblaciones de cada bioma. Los frutos, tanto inmaduros como maduros de cada bioma no mostraron adquisición neta de carbono; las hojas mostraron actividad fotosintética, éstas poseen estomas en ambas caras y los frutos carecen de ellos. Estos resultados permiten descartar la hipótesis de que el color verde de los frutos de T. corymbosus se encuentra asociado a la adquisición neta de carbono vía fotosíntesis y mantiene la necesidad de indagación de otras hipótesis sobre la variación del color de los frutos entre biomas.In some species fruits are green when they are ripe. This can be attributed to the ability to acquire carbon via photosynthesis, which reduces reproductive costs and increases nutritional reward for seed dispersers. The color of mature fruits of the mistletoe Tristerix corymbosus (Loranthaceae differ between biomes. In the Chilean matorral ripe fruits are yellow while in the temperate forest are green. Our objective was to determine whether or not fruits photosynthesize and if this ability varied with maturity stage and biome. We performed physiological measurements in plants from populations of each contrasting biome. Fruits did not denote carbon acquisition, regardless the biome or maturity stage. Leaves showed photosynthetic activity, they are amphistomatic

This Mars Exploration Rover Opportunity Pancam 'super resolution' mosaic of the approximately 6 m (20 foot) high cliff face of the Cape Verde promontory was taken by the rover from inside Victoria Crater, during the rover's descent into Duck Bay. Super-resolution is an imaging technique which utilizes information from multiple pictures of the same target in order to generate an image with a higher resolution than any of the individual images. Cape Verde is a geologically rich outcrop and is teaching scientists about how rocks at Victoria crater were modified since they were deposited long ago. This image complements super resolution mosaics obtained at Cape St. Mary and Cape St. Vincent and is consistent with the hypothesis that Victoria crater is located in the middle of what used to be an ancient sand dune field. Many rover team scientists are hoping to be able to eventually drive the rover closer to these layered rocks in the hopes of measuring their chemistry and mineralogy. This is a Mars Exploration Rover Opportunity Panoramic Camera image mosaic acquired on sols 1342 and 1356 (November 2 and 17, 2007), and was constructed from a mathematical combination of 64 different blue filter (480 nm) images.

Full Text Available Esta investigación explica la influencia que el rasgo psicológico locus de control, conjuntamente con las variables que definen el capital humano de un país -género, edad y educación-, ejercen sobre las actitudes hacia el empleo en la República de Cabo Verde. De entre estos rasgos demográficos del individuo, el género es analizado más profundamente debido al interés actual por reducir las desigualdades en razón de género en el mercado laboral. Los 448 cuestionarios recabados muestran que, en este país, los atributos demográficos edad y nivel de estudios, así como el rasgo de personalidad locus de control, son importantes determinantes de las actitudes hacia el empleo de la población activa. Los resultados ofrecen las bases sobre las que redirigir las políticas de empleo en Cabo Verde para afrontar los puntos débiles que limitan el desarrollo del mercado de trabajo y amenazan la integración social.

Full Text Available The Sonoran desert has a great variety of nutritional native plants, mainly from the leguminous family. Although in ancient times their products were used as food by native Americans, there is little information about their potential as a food source. For this reason, oils from the following seeds were studied: Acacia famesiana (huizache, Mimosa grahamii (gatuña, Cercidium microphyilium (palo verde 1, Cercidium sonorae (brea, Parkinsonia aculeata (palo verde 2, Olneya Tesota (palo fierro and Prosopis juliflora (mezquite.
Oils were extracted from the seeds with hexane, and contents ranged from 8.5 to 23.5 %. The physicochemical studies showed mostly unsaturated oils, as demonstrated by the iodine index, (101-147 units. Indexes of acidity, peroxides and free fatty acids were low and within the accepted values. Fatty acids were separated and quantified by gas chromatography. Linoleic and oleic acids were found to predominate. All extracted crude oils were of good quality, comparable to those from soybean, com, sunflower and carthamus.

Vieira, Nuno; Amado, Miguel; Pinho, Fernando

2017-02-01

Nowadays, the lack of adequate housing in Cape Verde is a growing problem. The migration of the population living in the countryside to the major cities generates an increase of the diameter of the cities. With the lack of economic power, the migrating families tend to occupy the land with houses which don't present proper conditions to living. Praia is the capital of Cape Verde and so on the biggest city of the country. This fact leads Praia to being the city with major economic power and job offer in all country. Consequently, Praia has developed the biggest slum of the Cape Verde and it is urgent to approach this problem in order to create solutions that reveal capacity to start solving it. Cape Verde's unique dry subtropical climate turns indispensable a careful resolution of the housing, in order to ensure the comfort of the occupants. The modular construction is a solution with potential to approach this problem with a fast and economic response. In order to answer the situation, this article introduces a modular solution in order to reach the needing of thermal comfort to the specific case of Praia.

Intraplate seismicity across the Cape Verde swell

The Cape Verde Archipelago ((15-17°N, 23-26°W) is located within the African plate, about 500km west of Senegal, in the African coast. The islands are located astride the Cape Verde mid-plate topographic swell, one of the largest features of its type in the world's ocean basins. The origin of this Cape Verde swell is still in debate. Previous determinations of the elastic thickness (Te) reveal a normal Te and a modest heat flow anomaly which suggest that the swell cannot be fully explained by uplift due to thermal reheating of the lithosphere by an underlying ‘‘hot spot'' and that other, deep-seated, mantle processes must be involved. The CV-PLUME (An investigation on the geometry and deep signature of the Cape Verde mantle plume) project intends to shape the geometry and deep origin of the Cape Verde mantle plume, via a combined study of seismic, magnetic, gravimetric and geochemical observations. Through this study we intend to characterize the structure beneath the archipelago from the surface down to the deep mantle. The core of this 3-year project was a temporary deployment of 39 Very Broad Band seismometers, across all the inhabited islands, to recorder local and teleseismic earthquakes. These instruments were operational from November 2007 to September 2008. In this work we report on the preliminary results obtained from the CV-PLUME network on the characterization of the local and regional seismicity. To detect the small magnitude seismic events the continuous data stream was screened using spectrograms. This proved to be a very robust technique in the face of the high short-period noise recorded by many of the stations, particularly during day time. The 10 month observation time showed that the background seismic activity in the Archipelago and surrounding area is low, with only a very few events recorded by the complete network. However, two clusters of earthquakes were detected close to the Brava Island, one to the NW and a second one, more active

Full Text Available The effects of various alternatives in managing the water from a coastal aquifer with sea-water intrusion problems (the river Verde alluvial aquifer, Almuñecar, Granada, Spain have been analyzed by means of a finite element approximation. The differential equation which describes the horizontal flow of groundwater and the movement of a sharp interface between the fresh and salt water is solved in a steady state regimen for boundaries with flow and open boundary conditions. This stationary solution has shown very accurate results in calculating freshwater potentials, thicknesses of fresh and salt water, discharges of fresh water and the intrusion of salt water along the coast. Various alternatives were simulated in the aquifer which included: the operation of the planned Otivar reservoir at the head of the catchment basin, changes in the location of extractions from the aquifer, and artificial recharge by urban waste water in the proximity of the coast. These simulations revealed that a considerable advance in the interface is to be expected if the current pumping exploitation continues and a significant part of the surface flow of the river Verde is channeled from the planned Otivar reservoir to irrigate the Almuñécar plain. On the other hand, the injection of urban waste water in the proximity of the coast would contribute to limiting the advance of the interface in the aquifer.

Is a changing climate affecting the tropical cyclone behavior of Cape Verde?

Science.gov (United States)

Emmenegger, T. W.; Mann, M. E.; Evans, J. L.

2016-12-01

An existing dataset of synthetic tropical cyclone (TC) tracks derived from climate change simulations were used to explore TC variability within a 250 km radius of the Cape Verde Islands (16.5388N, 23.0418W). The synthetic sets were examined according to genesis point location, track projection, intensity, frequency, and seasonality within the observational era (1851 AD to present). These factors of TC variability have been shown to be strongly related to climate oscillations, thus the historical era was grouped by the increasing and decreasing regimes of sea surface temperature (SST) in the main development region (MDR) of the Atlantic Ocean. Numerous studies have examined Atlantic Basin activity throughout this era; the goal of this study is to investigate possible variations in TC behavior around Cape Verde, ultimately determining whether Cape Verde experiences similar fluctuations in activity as observed basin-wide. We find that several facets of TC variability such as intensity, seasonality, and genesis point location around Cape Verde are not significantly different to that of the entire basin, thus forecasts of the entire basin in these respects may also apply to our site. A long-term trend of increasing TC frequency can be identified basin-wide within the observed set, yet activity around Cape Verde does not display this same behavior observably or in any synthetic set. A relationship between the location of genesis points and the regimes of SST fluctuation is shown to be existent. We find both more observed and synthetic genesis points within the vicinity of Cape Verde during cool periods, and an eastward and equatorward shift in cyclogenesis is evident during warm regimes. This southeastern shift in genesis points attributes to the increased intensities of TCs seen during periods of warmer SST. Years of increased SST are additionally linked to an earlier seasonality in Cape Verde.

Achieving engineering excellence at Palo Verde

International Nuclear Information System (INIS)

Prawlocki, F.C.

1989-01-01

Early in 1988, the management of the newly formed Palo Verde Nuclear Generating Station (PVNGS) Engineering and Construction Division was faced with a dilemma: how to build a competent, confident, efficient engineering organization in the face of increasing requirements and tightened fiscal controls. This paper discusses steps taken by Palo Verde to address actions taken to effect a smooth transition from construction to operations and the development of the Engineering Excellence Program. The Engineering Excellence Program will continue to evolve over time as the number of the NED's [Nuclear Engineering Department] personnel grown and processes are changed over the course of the next few years. As tasks from the Engineering Excellence Program action plan are completed, the results achieved are expected to be integrated into the routine business of the NED

Beginning in 1997, the Environmental Protection Agency (EPA) defined a contaminated section of the Palos Verdes Shelf region in southern California as a Superfund Site, initiating a continuing investigation of this area. The investigation involved the EPA, the U.S. Geological Survey (USGS), Science Applications International Corporation (SAIC), Los Angeles County Sanitation Districts (LACSD) data, and other allied agencies. In mid-2007, the Palos Verdes Shelf project team identified the need for additional data on the sediment properties and oceanographic conditions at the Palos Verdes Superfund Site and deployed seven bottom platforms, three subsurface moorings, and three surface moorings on the shelf. This additional data was needed to support ongoing modeling and feasibility studies and to improve our ability to model the fate of the effluent-affected deposit over time. It provided more detail on the spatial variability and magnitude of resuspension of the deposit during multiple storms that are expected to transit the region during a winter season. The operation began in early December 2007 and ended in early April 2008. The goal was to measure the sediment response (threshold of resuspension, suspended-sediment concentrations, and suspended-sediment transport rates) to bed stresses associated with waves and currents. Other objectives included determining the structure of the bottom boundary layer (BBL) relating nearbed currents with those measured at 10 m above bottom (mab) and comparing those with the long-term data from the LACSD Acoustic Doppler Current Profiler (ADCP) deployments for nearbed current speed and direction. Low-profile tripods with high-frequency ADCPs co-located with two of the large tripods were selected for this goal. This report describes the data obtained during the field program, the instruments and data-processing procedures used, and the archive that contains the data sets that have passed our quality-assurance procedures.

In order to have rightful, democratic, human and healthy cities it’s fundamental the human rights incorporation in city governance, which result in the management and public policy to extinguish social inequalities, discrimination practices in all individual segregation forms, social groups and communities, due to the habitation type and settlements location of their living. Aware of the importance of public policy study to understand social phenomena, the Policy of Habitation of Social Interest (HSI study allows the prediction of the actions impact of the State to the society and opens the way to the creation on new models that may help both the State and society for formulation process, implementation and evaluation of that same policy, as others which may intersects. On the basis of literature search and analysis of documents, from the understanding the concept of risk management, public policy, social vulnerability and Habitation of Social Interest, this essay searches the strategy identification, the actors, instruments and implementation meanings for HSI policies in Cape Verde; objectively identify the preventive measures to the risk mitigation associated to the habitation and consequent social vulnerability, and to recognize the difficulties inertly to its implementation.

Cape Verde petrel (Pterodroma feae) is currently considered near threatened, but little is known about its population size, breeding biology and on land threats, jeopardizing its management and conservation. To improve this situation, we captured, marked and recaptured (CMR) birds using mist-nets over 10 years; measured and sexed them; monitored up to 14 burrows, deployed GPS devices on breeders and analyzed activity data of geolocators retrieved from breeders in Fogo (Cape Verde). We set cat traps over the colony and investigated their domestic/feral origin by marking domestic cats from a nearby village with transponders, by deploying GPS devices on domestic cats and by performing stable isotope analyses of fur of the trapped and domestic cats. The population of Fogo was estimated to be 293 birds, including immatures (95% CI: 233-254, CMR modelling). Based on geolocator activity data and nest monitoring we determined the breeding phenology of this species and we found biometric differences between sexes. While monitoring breeding performance, we verified a still ongoing cat predation and human harvesting. Overall, data gathered from trapped cats without transponder, cats GPS trips and the distinct isotopic values between domestic and trapped cats suggest cats visiting the colony are of feral origin. GPS tracks from breeders showed birds left and returned to the colony using the sector NE of the islands, where high level of public lights should be avoided specially during the fledging period. Main threats for the Cape Verde petrel in the remaining breeding islands are currently unknown but likely to be similar to Fogo, calling for an urgent assessment of population trends and the control of main threats in all Cape Verde Islands and uplisting its conservation status.

Human leukocyte antigen (HLA)-A, -B, and -DRB1 polymorphisms were examined in the Cabo Verde and Guiné-Bissau populations. The data were obtained at high-resolution level, using sequence-based typing. The most frequent alleles in each locus was: A*020101 (16.7% in Guiné-Bissau and 13.5% in Cabo Verde), B*350101 (14.4% in Guiné-Bissau and 13.2% in Cabo Verde), DRB1*1304 (19.6% in Guiné-Bissau), and DRB1*1101 (10.1% in Cabo Verde). The predominant three loci haplotype in Guiné-Bissau was A*2301-B*1503-DRB1*1101 (4.6%) and in Cabo Verde was A*3002-B*350101-DRB1*1001 (2.8%), exclusive to northwestern islands (5.6%) and absent in Guiné-Bissau. The present study corroborates historic sources and other genetic studies that say Cabo Verde were populated not only by Africans but also by Europeans. Haplotypes and dendrogram analysis shows a Caucasian genetic influence in today's gene pool of Cabo Verdeans. Haplotypes and allele frequencies present a differential distribution between southeastern and northwestern Cabo Verde islands, which could be the result of different genetic influences, founder effect, or bottlenecks. Dendrograms and principal coordinates analysis show that Guineans are more similar to North Africans than other HLA-studied sub-Saharans, probably from ancient and recent genetic contacts with other peoples, namely East Africans.

The cone snails of Cape Verde: Marine endemism at a terrestrial scale

Directory of Open Access Journals (Sweden)

Howard Peters

2016-07-01

Full Text Available Cape Verde in the Eastern Atlantic is typical of many island groups in supporting a wealth of endemic species both terrestrial and marine. Marine gastropod molluscs of the genus Conus, commonly known as cone snails, occur in coastal tropical waters throughout the globe, but in Cape Verde their endemism reaches its apogee with 53 out of 56 species occurring nowhere else, the majority of which are restricted to single islands and frequently to single bays. However, Cape Verde is rapidly moving to a tourism-based economy with a projected boom in infrastructure development often coincidental with the shallow-water habitat of many range-restricted Conus. The conservation assessment of Conus to standards of the International Union for the Conservation of Nature (IUCN Red List of Endangered Species, found that 45.3% of 53 species assessed from Cape Verde are threatened or near-threatened with extinction compared to 7.4% of 579 species in the rest of the world. The only three Conus species globally assessed as Critically Endangered and on the cusp of extinction are all endemic to Cape Verde. Our analysis of Conus species distribution, together with spatial data of coastal protected areas and tourism development zones, identify important areas for future research and new marine protection. Our findings show that endemism with its associated risks for Conus in Cape Verde has worldwide parallels with many non-marine taxa, while our proposed strategy for Conus conservation extends beyond the confines of the country and this taxonomic group.

Bats of Mesa Verde National Park, Colorado: composition, reproduction, and roosting habits.

We determined the bat fauna at Mesa Verde National Park (Mesa Verde) in 2006 and 2007, characterized bat elevational distribution and reproduction, and investigated roosting habits of selected species. We captured 1996 bats of 15 species in mist nets set over water during 120 nights of sampling and recorded echolocation calls of an additional species. The bat fauna at Mesa Verde included every species of bat known west of the Great Plains in Colorado, except the little brown bat (Myotis lucifugus). Some species showed skewed sex ratios, primarily due to a preponderance of males. Thirteen species of bats reproduced at Mesa Verde. Major differences in spring precipitation between the 2 years of our study were associated with differences in reproductive rates and, in some species, with numbers of juveniles captured. Reduced reproductive effort during spring drought will have a greater impact on bat populations with the forecasted increase in aridity in much of western North America by models of global climate change. We radiotracked 46 bats of 5 species to roosts and describe the first-known maternity colonies of spotted bats (Euderma maculatum) in Colorado. All 5 species that we tracked to diurnal roosts relied almost exclusively on rock crevices rather than trees or snags, despite the presence of mature forests at Mesa Verde and the use of trees for roosts in similar forests elsewhere by some of these species. Comparisons with past bat surveys at Mesa Verde and in surrounding areas suggest no dramatic evidence for effects of recent stand-replacing fires on the composition of the bat community.

Highlights: • Neutronic/thermal hydraulic event in Laguna Verde is modeled. • A good agreement is obtained between SIMULATE-3K results and data plant for frequency and DR. • Other noise analysis techniques are used for the same purpose with good agreement. • Validation of SIMULATE-3K for stability analysis of Laguna Verde is confirmed - Abstract: Boiling Water Reactors are two phase flow systems which are susceptible to different types of flow instabilities. Among these are the coupled neutronic/thermal-hydraulic instabilities, these may compromise established fuel safety limits. These instabilities are characterized by periodic core-power and hydraulic oscillations. SIMULATE-3K code has been tested for stability analysis for several benchmarks, however to qualify the SIMULATE-3K code for a particular power plant a specific reactor plant analysis must be done. In this paper, the plant model of Laguna Verde Nuclear Power Plant is built and SIMULATE-3K is tested against the 1995 coupled neutronic/thermal-hydraulic instability event of Laguna Verde. Results obtained show the adequacy of this code to specific Laguna Verde power plant stability analysis.

Low concentrations of persistent organic pollutants (POPs) in air at Cape Verde.

Ambient air is a core medium for monitoring of persistent organic pollutants (POPs) under the Stockholm Convention and is used in studies of global transports of POPs and their atmospheric sources and source regions. Still, data based on active air sampling remain scarce in many regions. The primary objectives of this study were to (i) monitor concentrations of selected POPs in air outside West Africa, and (ii) to evaluate potential atmospheric processes and source regions affecting measured concentrations. For this purpose, an active high-volume air sampler was installed on the Cape Verde Atmospheric Observatory at Cape Verde outside the coast of West Africa. Sampling commenced in May 2012 and 43 samples (24h sampling) were collected until June 2013. The samples were analyzed for selected polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), hexachlorobenzene (HCB) and chlordanes. The concentrations of these POPs at Cape Verde were generally low and comparable to remote sites in the Arctic for several compounds. Seasonal trends varied between compounds and concentrations exhibited strong temperature dependence for chlordanes. Our results indicate net volatilization from the Atlantic Ocean north of Cape Verde as sources of these POPs. Air mass back trajectories demonstrated that air masses measured at Cape Verde were generally transported from the Atlantic Ocean or the North African continent. Overall, the low concentrations in air at Cape Verde were likely explained by absence of major emissions in areas from which the air masses originated combined with depletion during long-range atmospheric transport due to enhanced degradation under tropical conditions (high temperatures and concentrations of hydroxyl radicals).

Full Text Available En este artículo se presentan los resultados del estudio de composición de Residuos Sólidos de la Municipalidad de Esparza, estos serán utilizados con el objetivo de determinar la factibilidad técnica y económica para construir un relleno sanitario municipal discriminado. La Municipalidad de Esparza, actualmente, utiliza el vertedero de Zagala, el cual no cumple con los estándares adecuados para el manejo de estos materiales y se ha convertido en un problema ambiental para la región. Por esta razón, en esta investigación se propuso realizar un estudio físico de los desechos sólidos en tres sectores del cantón de Esparza.Los resultados más prominentes de esta investigación indican que en el cantón el 74.5% de los desechos sólidos pueden ser aprovechados en prácticas de producción de abonos orgánicos, compost y reciclamiento; mientras que un 25.5% no tendrían ningún aprovechamiento y deberían ser dispuestos en un relleno sanitario, situación que, actualmente, no se hace pues estos mismos son enviados al botadero de Zagala. Se espera que este estudio sirva de base para proponer un plan de manejo de los residuos sólidos, apoye los esfuerzos de educación ambiental, sirva de sustento para seleccionar los materiales con potencial de reciclable y defina la cantidad de materiales que irán al relleno sanitario municipal.

Full Text Available Chilli (Capsicum annuum L. is regarded as one of the main commercial vegetable and spice crops at the global level. Maximum diversity can be noted among the cultivars/landraces available in India with respect to shape, size, yield, quality, and other traits. The present experiment was conducted to identify the most promising chilli variety suited for green and dry purposes, to study the genetic variability for different traits and to assess the association of different yield attributing traits with the green and dry yield of chilli. Thirty four genotypes were characterized during a 2-yr period. Most of the genotypes possessed the character constellation of C. annuum. Two genotypes, ‘Chaitali Pointed’ and ‘BC CH Sel-4’ were found most promising with respect to green fruit yield (272.79 g, 221.10 g per plant and dry fruit yield (54.56 g, 44.44 g per plant. Phenotypic and Genotypic Coefficient of Variation values for green fruit weight (119.95%, 111.26%, green fruit girth (89.76%, 48.93%, weight of red ripe fruit (112.02%, 111.93%, weight of dry fruit (111.63%, 110.97% and number of fruits per plant (86.05%, 85.02% were recorded to be high. Green fruit yield per plant, ascorbic acid content, and number of fruits per plant also showed very high broad-sense heritability and genetic advance. From the study of correlation and path coefficient analyses, the number of fruits per plant, green fruit length for green chilli, weight of dry fruit and the number of fruits per plant for dry chilli were found to the most important selection indices.El ají (Capsicum annuum L. es considerado como uno de los principales cultivos comerciales de vegetales y especias a nivel mundial.

Living With Parasites in Palo Verde National Park

Eben Kirksey

2012-11-01

Full Text Available Bruno Latour has tried to bring a parliamentary democracy to the domain of nature. Wading through the swamps of Palo Verde, a national park in the Guanacaste Province of Costa Rica, and wandering onto neighbouring agricultural lands, I failed to find a central place where people were speaking for nature. Departing from a failed attempt to speak for another species (the fringe-toed foam frog, this paper considers how diverging values and obligations shape relationships in multi-species worlds. As spokespersons articulated competing visions of nature on the borderlands of Palo Verde, multiple social and ecological worlds went to war. The haunting specter of capital joined the fray—animating the movements of cattle, grasses with animal rhizomes, rice seeds, and flighty ducks across national borders and through fragmented landscapes. Amidst this warfare, the fringe-toed foam frog was just one tenacious parasite, a noisy agent eating at the table of another, which began to flourish in worlds designed with the well-being of others in mind. Cattails, charismatic birds, and a multitude of insects began interrupting human dreams and schemes. Final solutions to the problem of living with parasites failed in Palo Verde. Humans and parasites, who became para-selves of one another, maintained an abiding presence in the landscape.

Laguna Verde: the nuclear debate in Mexico

International Nuclear Information System (INIS)

Weinberg, Bill.

1987-01-01

Mexico in planning to start up its first nuclear power station at Laguna Verde in the state of Veracruz (1988). The history of the plant is traced; it should have been finished by 1974. Both the fuel and the technology have been imported from the United States for Laguna Verde. The design, a Mark II Boiling Water Reactor, is controversial and there are doubts as to its safety. Opposition to the plant on safety and environmental grounds has grown. In April 1987 a 'Chernobyl anniversary' demonstration had 10,000 protesters and opponents of the plant are becoming more militant. The main opposition is from environmental and 'Green' groups but also includes intellectuals. However, politically, Mexico would find it embarrassing to cancel the plant and also it wants to be seen as a 'First World' rather than a 'Third World' country. (U.K.)

Effects of past and future groundwater development on the hydrologic system of Verde Valley, Arizona

Science.gov (United States)

Garner, Bradley D.; Pool, D.R.

2013-01-01

Communities in central Arizona’s Verde Valley must manage limited water supplies in the face of rapidly growing populations. Developing groundwater resources to meet human needs has raised questions about the effects of groundwater withdrawals by pumping on the area’s rivers and streams, particularly the Verde River. U.S. Geological Survey hydrologists used a regional groundwater flow model to simulate the effects of groundwater pumping on streamflow in the Verde River. The study found that streamflow in the Verde River between 1910 and 2005 had been reduced as the result of streamflow depletion by groundwater pumping, also known as capture. Additionally, using three hypothetical scenarios for a period from 2005 to 2110, the study’s findings suggest that streamflow reductions will continue and may increase in the future.

La composición taxonómica de la macrofauna asociada al proceso de descomposición del follaje de leucaena estuvo constituida por cuatro Phylum, seis clases y siete órdenes. El 97% de los organismos eran detritívoros y el 3% depredadores. El tipo de bolsa no influyó en la descomposición del follaje y los factores climáticos desempeñaron un rol decisivo en este proceso.

Groundwater resources of Mosteiros basin, island of Fogo, Cape Verde, West Africa

Science.gov (United States)

Heilweil, Victor M.; Gingerich, Stephen B.; Plummer, Niel; Verstraeten, Ingrid M.

2010-01-01

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

Telemedicine and e-health have been suggested as one solution for closing the health disparity gap between the developed world and the developing world. Yet evidence is lacking from current successful programs in the developing world and, in particular, from sub-Saharan Africa. The primary objective of our study was to present the preliminary results of our efforts in building the Integrated Telemedicine and e-Health Program for Cabo Verde (ITeHP-CV), with an emphasis on initial utilization and results. This is a prospective study of data collected while we worked to establish a fully functional, integrated national telemedicine network and virtual education network in Cabo Verde. We used the International Virtual e-Hospital Foundation strategic approach known as "initiate-build-operate-transfer" over a 26-month period (November 2011-December 2013). We describe herein the five main pillars of this process that have been implemented: (1) capacity building; (2) network development and deployment of equipment; (3) implementation of clinical telemedicine; (4) implementation of activities related to continuing medical education, delivered from within the country and from abroad; and (5) establishment and use of the electronic virtual library. Based on comprehensive technical and medical assessment of the country's needs, 10 fully functional telemedicine centers in all nine inhabited islands of the Republic of Cabo Verde have been established. RESULTS are presented under the five main pillars of capacity building, network deployment, implementation of clinical telemedicine, implementation of continuing medical education activities, and establishment of the electronic virtual library. The ITeHP-CV has been successfully launched, and the initial results are encouraging. The continuity of the program and sustainability are primary goals once the program is transferred fully to the Ministry of Health of Cabo Verde. A long-term follow-up study is required in order to ensure

DDE in sediments of the Palos Verdes shelf, California: In situ transformation rates and geochemical fate

Eganhouse, R.P.; Pontolillo, J.

2008-01-01

From 1947 to 1971 the world's largest manufacturer of DDT discharged process wastes into the sewers of Los Angeles County. Roughly 870-1450 t of DDT were released to the ocean off Palos Verdes, CA, a portion of which (???100 t) resides in sediments on the continental shelf and slope. The most abundant DDT compound in the sediments, p,p???-DDE, is degrading by reductive dechlorination, butthe rate of transformation and factors controlling it are not well understood. In order to estimate in situ transformation rates and predict the long-term fate of p,p???-DDE, box cores were collected in 1992 and 2003 from a single location on the Palos Verdes Shelf and analyzed for 8 DDT compounds and 84 polychlorinated biphenyl (PCB) congeners. The PCBs show no evidence of dechlorination, and inventories did not change between 1992 and 2003. By contrast, the inventory of p,p???-DDE decreased by 43%, whereas that of p,p???-DDMU, the putative reductive dechlorination product increased by 34%. The first-order transformation rate for p,p???-DDE at the study site is 0.051 ?? 0.006 yr-1. A multistep reaction model suggests that inventories of p,p???-DDE and p,p???-DDMU will continue to decline, whereas that of p,p???-DDNU will reach a maximum around 2014.

Full Text Available Descoberto entre 1460 e 1462, o Arquipélago de Cabo Verde, situado no Oceano Atlântico, constituiu ao longo de vários séculos, escala obrigatória dos navios que faziam as ligações atlânticas entre os portos das Américas, da Europa e da África Graças a sua situação privilegiada, o espaço cabo-verdiano não foi um mero ponto de reabastecimento, mas também um importante ponto de cruzamento de culturas e de raças. Pretende-se, neste texto, abordar o papel que Cabo Verde teve no Atlântico incidindo, particularmente, na dimensão cultural resultante do contacto entre povos e culturas provenientes de diferentes paragens que se fixaram no arquipélago ou que por aqui passaram. Procurar-se-á evidenciar não só a importância que Cabo Verde teve enquanto ponto de passagem obrigatória mas, sobretudo, as contribuições que mais marcadamente se denunciaram, isto é, os apports culturais que mais se acentuaram em Cabo Verde, como processos recebidos dos estrangeiros que por estas ilhas se cruzaram.The Archipelago of Cape Verde, discovered between 1460 and 1462, and situated in the Atlantic Ocean, had been considered for centuries one of the mandatory harbours of the ships that sailed across the Atlantic to the ports of America, Europe and Africa. Because of its strategic location, Cape Verdean anchorage was considered not only the supplying point, but also an important melting pot of races and cultures. It is intended to highlight the role of Cape Verde in the Atlantic focusing particularly on the cultural aspect, as a result of the influence of cultures and origins of people who had settled in or had passed by the archipelago. It is also aimed to underline the importance of Cape Verde as a mandatory gateway but, above all, to underline the remarkable contributions, such as the cultural “apports” by which Cape Verde were gripped, like processes brought by the foreigners who crossed these islands.

Sugar cane spirits are some of the most popular alcoholic beverages consumed in Cape Verde. The sugar cane spirit industry in Cape Verde is based mainly on archaic practices that operate without supervision and without efficient control of the production process. The objective of this work was to evaluate samples of industrial and alembic sugar cane spirits from Cape Verde and Ceará, Brazil using principal component analysis. Thirty-two samples of spirits were analyzed, twenty from regions of the islands of Cape Verde and twelve from Ceará, Brazil. Of the samples obtained from Ceará, Brazil seven are alembic and five are industrial spirits. The components analyzed in these studies included the following: volatile organic compounds (n-propanol, isobutanol, isoamylic, higher alcohols, alcoholic grade, acetaldehyde, acetic acid, acetate); copper; and sulfates.

2000-09-01

This research is an examination of the relationship between loneliness and a number of psychosocial variables (e.g., affective state, cultural issues, gender, age) among adolescents and young adults from Cape Verde and Portugal. Two studies are presented. The participants in the first study were 285 adolescents from Cape Verde and 202 from Portugal, and in the second study there were 134 college students from Cape Verde and 112 from Portugal. The following instruments were administered to all the participants in both studies: The Revised UCLA Loneliness Scale (D. Russell, L. Peplau, & C. Cutrona, 1980), the Neuroticism Scale (J. Barros, 1999), the Optimism Scale (J. Barros, 1998), the Social Anxiety subscale (A. Fenigstein, M. Scheier, & A. Buss, 1975), and the Satisfaction With Life Scale (E. Diener, R. Emmons, R. Larsen, & S. Griffin, 1985). No ethnic or gender differences were found for loneliness between the two groups. For both groups, the most prominent predictors of loneliness were neuroticism and dissatisfaction with life. However, as expected, the adolescent group recorded higher scores for loneliness than did the college students.

Highlights: • The design of 2 off-grid electrification projects in Cape Verde is developed. • Configurations with hybrid renewable energy systems and micro-grids are considered. • A detailed micro-scale wind resource assessment is carried out. • An optimization model is used in order to support the design. • The proposed system is economically beneficial in comparison with diesel generation. - Abstract: Even though Cape Verde has high wind and solar energy resources, the conventional strategy for increasing access to electricity in isolated rural areas is by centralized microgrids with diesel generators. In this study, the design of 2 off-grid electrification projects based on hybrid wind–photovoltaic systems in Cape Verde is developed and analyzed. The design considers some significant novelty features in comparison with previous studies. First a detailed wind resource assessment is carried out combining meso-scale wind climate data and a specialized micro-scale wind flow model. Then a mathematical model is used for the design of off-grid projects considering a combination of individual systems and microgrids. In this study, locations far from the demand points are also considered as possible generation points. Various design configurations are analyzed and compared. The proposed configurations exploit the highest wind potential areas and are economically beneficial in comparison with diesel generator systems

2013-01-01

The objectives of this study were to (1) conduct an elemental characterization of airborne particles sampled in Cape Verde and (2) assess the influence of Sahara desert on local suspended particles. Particulate matter (PM(10)) was collected in Praia city (14°94'N; 23°49'W) with a low-volume sampler in order to characterize its chemical composition by k0-INAA. The filter samples were first weighed and subsequently irradiated at the Portuguese Research Reactor. Results showed that PM(10) concentrations in Cape Verde markedly exceeded the health-based air quality standards defined by the European Union (EU), World Health Organization (WHO), and U.S. Environmental Protection Agency (EPA), in part due to the influence of Sahara dust transport. The PM(10) composition was characterized essentially by high concentrations of elements originating from the soil (K, Sm, Co, Fe, Sc, Rb, Cr, Ce, and Ba) and sea (Na), and low concentrations of anthropogenic elements (As, Zn, and Sb). In addition, the high concentrations of PM measured in Cape Verde suggest that health of the population may be less affected compared with other sites where PM(10) concentrations are lower but more enriched with toxic elements.

Soil and Water Conservation Strategies in Cape Verde (Cabo Verde in Portuguese and Their Impacts on Livelihoods: An Overview from the Ribeira Seca Watershed

Full Text Available Severe land degradation has strongly affected both people’s livelihood and the environment in Cape Verde (Cabo Verde in Portuguese, a natural resource poor country. Despite the enormous investment in soil and water conservation measures (SWC or SLM, which are visible throughout the landscape, and the recognition of their benefits, their biophysical and socioeconomic impacts have been poorly assessed and scientifically documented. This paper contributes to filling this gap, by bringing together insights from literature and policy review, field survey and participatory assessment in the Ribeira Seca Watershed through a concerted approach devised by the DESIRE project (the “Desire approach”. Specifically, we analyze government strategies towards building resilience against the harsh conditions, analyze the state of land degradation and its drivers, survey and map the existing SWC measures, and assess their effectiveness against land degradation, on crop yield and people’s livelihood. We infer that the relative success of Cape Verde in tackling desertification and rural poverty owes to an integrated governance strategy that comprises raising awareness, institutional framework development, financial resource allocation, capacity building, and active participation of rural communities. We recommend that specific, scientific-based monitoring and assessment studies be carried out on the biophysical and socioeconomic impact of SLM and that the “Desire approach” be scaled-up to other watersheds in the country.

Two concomitant dengue 3 (DEN-3) epidemics occurred in Cape Verde Archipelago and Senegal between September and October 2009. Aedes aegypti was identified as the vector of these epidemics as several DEN-3 virus strains were isolated from this species in both countries. The susceptibility to pyrethroids, organochlorine, organophosphates and carbamate was investigated in two field strains of Aedes aegypti from both countries using WHO diagnostic bioassay kits in order to monitor their the current status of insecticide susceptibility. The two tested strains were highly resistant to DDT. The Cape Verde strain was found to be susceptible to all others tested insecticides except for propoxur 0.1%, which needs further investigation. The Dakar strain was susceptible to fenitrothion 1% and permethrin 0.75%, but displayed reduced susceptibility to deltamethrin, lambda-cyhalothrin and propoxur. As base-line results, our observations stress a careful management of insecticide use for the control of Ae. aegypti. Indeed, they indicate that DDT is no longer efficient for the control of Ae. aegypti populations in Cape Verde and Dakar and further suggest a thorough follow-up of propoxur susceptibility status in both sites and that of deltamethrin and lambda-cyhalothrin in Ae. aegypti populations in Dakar. Thus, regular monitoring of susceptibility is greatly needed as well as the knowing if this observed resistance/susceptibility is focal or not and for observed resistance, the use of biochemical methods is needed with detailed comparison of resistance levels over a large geographic area. Aedes aegypti, Insecticides, Susceptibility, Cape Verde, Senegal.

Adaptabilidade na produção de massa verde e grãos de genótipos de milho no Tocantins

Directory of Open Access Journals (Sweden)

Edmar Vinícius de Carvalho

Full Text Available Condições distintas de cultivo fazem com que a resposta dos genótipos seja diferente em cada situação. Para amenizar o efeito desta interação são realizadas análises de adaptabilidade e estabilidade, que auxiliam na escolha dos genótipos. Porém, muitas vezes, um genótipo apresenta diversas finalidades, causando problemas ao agricultor em algumas situações e, o uso de genótipos específicos, poderia ser uma solução. O objetivo desta pesquisa foi estudar a adaptabilidade e estabilidade de genótipos de milho na região Centro-Sul do Estado do Tocantins, e classificá-los, quanto a tendência da finalidade produtiva: grãos ou massa verde. Foram realizados oito experimentos em dois municípios do Tocantins na entressafra 2010 e na safra 2010/2011, sendo avaliados 16 genótipos de milho. Avaliou-se a massa verde total da planta e a produção de grãos (em g planta-1, as quais foram usadas na análise de adaptabilidade e estabilidade e, posteriormente buscou-se classificar a tendência da finalidade produtiva dos genótipos. Os genótipos P09, P12, P10, H02 e H01 apresentaram classificação do coeficiente de regressão superior na produção de grãos em relação à massa verde total da planta, acontecendo o contrário com os genótipos P02 e P01. O genótipo H01, quanto à produção de grãos, foi adaptado a ambientes favoráveis e apresentou tendência da finalidade produtiva para esta característica. Ao contrário dos genótipos P08 e P02, que foram adaptados a ambos ambientes e a ambientes favoráveis, respectivamente, quanto à massa verde total da planta e, obtiveram tendência da finalidade produtiva para esta característica.

The human immunodeficiency virus type 1 (HIV-1) subtype G is the most prevalent and second most prevalent HIV-1 clade in Cape Verde and Portugal, respectively; but there is no information about the origin and spatiotemporal dispersal pattern of this HIV-1 clade circulating in those countries. To this end, we used Maximum Likelihood and Bayesian coalescent-based methods to analyze a collection of 578 HIV-1 subtype G pol sequences sampled throughout Portugal, Cape Verde and 11 other countries from West and Central Africa over a period of 22 years (1992 to 2013). Our analyses indicate that most subtype G sequences from Cape Verde (80%) and Portugal (95%) branched together in a distinct monophyletic cluster (here called G(CV-PT)). The G(CV-PT) clade probably emerged after a single migration of the virus out of Central Africa into Cape Verde between the late 1970s and the middle 1980s, followed by a rapid dissemination to Portugal a couple of years later. Reconstruction of the demographic history of the G(CV-PT) clade circulating in Cape Verde and Portugal indicates that this viral clade displayed an initial phase of exponential growth during the 1980s and 1990s, followed by a decline in growth rate since the early 2000s. Our data also indicate that during the exponential growth phase the G(CV-PT) clade recombined with a preexisting subtype B viral strain circulating in Portugal, originating the CRF14_BG clade that was later disseminated to Spain and Cape Verde. Historical and recent human population movements between Angola, Cape Verde and Portugal probably played a key role in the origin and dispersal of the G(CV-PT )and CRF14_BG clades.

2015-12-01

Full Text Available Com o objetivo analisar a influência do ceticismo e da preocupação ambiental na percepção do indivíduo para a intenção de compra e compra declarada de produtos verdes no varejo, foi realizado um survey com 1233 consumidores para observar este efeito na relação entre intenção e compra declarada de produtos verdes e entender a disposição do consumidor em transformar sua preocupação ambiental e sua confiança no apelo verde do produto em prática. Como resultado, foi observado que o consumidor leva mais em consideração a sua rotina de compra e a sua experiência passada do que a preocupação ambiental e a influência de propagandas com apelo verde. Sendo assim, o consumo de produtos verdes no varejo precisa de mecanismos voltados para a mudança de habito e quebra de paradigmas (consumidor e varejista.

2013-06-01

The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season verde plant bug density measurement, three in-season plant injury measurements, and two at-harvest damage measurements were taken in 15 cotton fields in South Texas, 2010. Linear regression selected two measurements as potentially useful indicators of at-harvest damage: verde plant bug density (adjusted r2 = 0.68; P = 0.0004) and internal boll injury of the carpel wall (adjusted r2 = 0.72; P = 0.004). Considering use of multiple measurements, a stepwise multiple regression of the four in-season measurements selected a univariate model (verde plant bug density) using a 0.15 selection criterion (adjusted r2 = 0.74; P = 0.0002) and a bivariate model (verde plant bug density-internal boll injury) using a 0.25 selection criterion (adjusted r2 = 0.76; P = 0.0007) as indicators of at-harvest damage. In a validation using cultivar and water regime treatments experiencing low verde plant bug pressure in 2011 and 2012, the bivariate model performed better than models using verde plant bug density or internal boll injury separately. Overall, verde plant bug damaging cotton bolls exemplified the benefits of using multiple in-season measurements in pest monitoring programs, under the challenging situation when at-harvest damage results from a sequence of plant responses initiated by in-season insect feeding.

Dengue is a potentially fatal mosquito-borne infection with 50 million cases per year and 2.5 billion people vulnerable to the disease. This major public health problem has recurrent epidemics in Latin America and occurred recently in Cape Verde and Madeira Island. The lack of anti-viral treatment or vaccine makes the control of mosquito vectors a high option to prevent virus transmission. Essential oil (EO) constituents can affect insect's behaviour, being potentially effective in pest control. The present study evaluated the potential use of Foenicultm vulgare (fennel) EO in the control of the dengue vector Aedes aegypti. EOs isolated from fennel aerial parts collected in Cape Verde and from a commercial fennel EO of Portugal were analysed by NMR, GC and GC-MS. trans-Anethole (32 and 30%, respectively), limonene (28 and 18%, respectively) and fenchone (10% in both cases) were the main compounds identified in the EOs isolated from fennel from Cape Verde and Portugal, respectively. The larvicidal activity of the EOs and its major constituents were evaluated, using WHO procedures, against third instar larvae ofAe. aegypti for 24 h. Pure compounds, such as limonene isomers, were also assayed. The lethal concentrations LC50, C90 and LC99 were determined by probit analysis using mortality rates of bioassays. A 99% mortality of Ae. aegypti larvae was estimated at 37.1 and 52.4 µL L-1 of fennel EOs from Cape Verde and Portugal, respectively. Bioassays showed that fennel EOs from both countries displayed strong larvicidal effect against Ae. aegypti, the Cape Verde EO being as active as one of its major constituents, (-)-limonene.

Verde Macael: A Serpentinite Wrongly Referred to as a Marble

Directory of Open Access Journals (Sweden)

Santiago del Barrio

2013-02-01

Full Text Available Serpentinites are used in both exterior and interior locations, but not all serpentinites are equal: they vary in physical-mechanical behavior and are not all suitable for similar uses. The serpentinites most commonly used worldwide come from India, Pakistan or Egypt. Spain has traditionally quarried two ultramafic massifs, one in Galicia (Verde Pirineos and one in Andalucía (Verde Macael. Some of these quarries were small family-run businesses. In both cases, these rocks are commercially available as “green marble.” These serpentinites commonly have a high degree of carbonation, but the process does not always take place with the same intensity. Carbonate can act as a cementing agent of the other phases, increasing the mechanical strength parameters. As a result, an improvement in the strength conditions is achieved, but a misinterpretation of the suitability of the rock may occur because a perception among users that “green marble” is similar to geologically defined marble. This may lead to inappropriate applications as an ornamental stone. At a time of economic crisis in Europe, the natural stone sector is encouraged to invest in research to identify the best quality products that can compete profitably with those currently being imported from other countries. This paper provides a comparison of properties of the Verde Macael serpentinite with a true marble in the hope of contributing to improving the natural stone industrial sector.

In 2010 the nuclear power plant of Laguna Verde will implement the extended power upbeat in both units of the plant. Agree with methodology of NEDC-33004P-A, (constant pressure power up rate), and the source term of core, for accidents evaluations, were increased in proportion to the ratio of power level. This means that for the case of a design basis accident of loss of coolant an increase of power of 15% originated an increase of 15% in dose to main control room. Using the method of NEDC-33004P-A to extended power upbeat conditions was determined that the dose value to main control room is very near to regulatory limit established by SRP 6.4. By the above and in order to recover the margin, the nuclear power plant of Laguna Verde will calculate an alternative source term following the criteria established in RG 1.183 (alternative radiological source term for evaluating DBA at nuclear power reactor). This approach also have a more realistic dose value using the criterion of 10-CFR-50.67, in addition is predicted to get the benefit of additional operational flexibilities. This paper present the proposal of implementing the alternative source term in Laguna Verde. (Author)

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

Arizona Public Service Company (APS) is investigating changes to the Palo Verde Inservice Testing (IST) Program that are intended to result in the reduction of the required test frequency for various valves in the American Society of Mechanical Engineers (ASME) Section XI IST program. The analytical techniques employed to select candidate valves and to demonstrate that these frequency reductions are acceptable are risk based. The results of the Palo Verde probabilistic risk assessment (PRA), updated in June 1994, and the risk significant determination performed as part of the implementation efforts for 10 CFR 50.65 (the maintenance rule) were used to select candidate valves for extended test intervals. Additional component level evaluations were conducted by an 'expert panel.' The decision to pursue these changes was facilitated by the ASME Risk-Based Inservice Testing Research Task Force for which Palo Verde is participating as a pilot plant. The NRC's increasing acceptance of cost beneficial licensing actions and risk-based submittals also provided incentive to seek these changes. Arizona Public Service is pursuing the risk-based IST program modification in order to reduce the unnecessary regulatory burden of the IST program through qualitative and quantitative analysis consistent with maintaining a high level of plant safety. The objectives of this project at Palo Verde are as follows: (1) Apply risk-based technologies to IST components to determine their risk significance (i.e., high or low). (2) Apply a combination of deterministic and risk-based methods to determine appropriate testing requirements for IST components including improvement of testing methods and frequency intervals for high-risk significant components.

Assessment of vibration anomalies of main steam lines at Palo Verde-3

Amr, A.; Landstrom, C.; Maxwell, H.; Miller, J.S.; Lynch, J.J.

1996-01-01

Historically, flow induced vibration in piping systems that transport liquid has presented problems for plant designers. When evaluating a vibration problem, it is always important to determine the forcing frequencies from different phenomena and the natural frequencies of the system as an integral part of establishing the root cause of the problem. Since in most cases of large vibration and noise levels, the natural frequency of the system and the frequency of the flow induced vibration are very close, determining the natural frequency of the system is important. Palo Verde Unit-3 exhibited a vibration problem where identification of the root cause was difficult. A Palo Verde team was created which consisted of engineers from different on-site departments and support from consultants. The process used to determine the root cause for the vibration/noise problem on Main Steam Supply System (MSSS) steam line 2 at Palo Verde Unit 3 is discussed in this paper. Since the root cause was not readily apparent, a finite element model was constructed to determine the natural frequency of the piping system. The finite element model consisted of a portion of the main steam lines, including a sample line which traverses the main steam line

Due to their great species and ecological diversity as well as their capacity to produce hundreds of different toxins, cone snails are of interest to evolutionary biologists, pharmacologists and amateur naturalists alike. Taxonomic identification of cone snails still relies mostly on the shape, color, and banding patterns of the shell. However, these phenotypic traits are prone to homoplasy. Therefore, the consistent use of genetic data for species delimitation and phylogenetic inference in this apparently hyperdiverse group is largely wanting. Here, we reconstruct the phylogeny of the cones endemic to Cabo Verde archipelago, a well-known radiation of the group, using mitochondrial (mt) genomes. The reconstructed phylogeny grouped the analyzed species into two main clades, one including Kalloconus from West Africa sister to Trovaoconus from Cabo Verde and the other with a paraphyletic Lautoconus due to the sister group relationship of Africonus from Cabo Verde and Lautoconus ventricosus from Mediterranean Sea and neighboring Atlantic Ocean to the exclusion of Lautoconus endemic to Senegal (plus Lautoconus guanche from Mauritania, Morocco, and Canary Islands). Within Trovaoconus, up to three main lineages could be distinguished. The clade of Africonus included four main lineages (named I to IV), each further subdivided into two monophyletic groups. The reconstructed phylogeny allowed inferring the evolution of the radula in the studied lineages as well as biogeographic patterns. The number of cone species endemic to Cabo Verde was revised under the light of sequence divergence data and the inferred phylogenetic relationships. The sequence divergence between continental members of the genus Kalloconus and island endemics ascribed to the genus Trovaoconus is low, prompting for synonymization of the latter. The genus Lautoconus is paraphyletic. Lautoconus ventricosus is the closest living sister group of genus Africonus. Diversification of Africonus was in allopatry

Lapão, Luís Velez; Correia, Artur

2015-01-01

This paper addresses the role of international telemedicine services in supporting the evacuation procedures from Cape Verde to Portugal, enabling better quality and cost reductions in the management of the global health system. The Cape Verde, as other African countries, health system lacks many medical specialists, like pediatric cardiologists, neurosurgery, etc. In this study, tele-cardiology shows good results as diagnostic support to the evacuation decision. Telemedicine services show benefits while monitoring patients in post-evacuation, helping to address the lack of responsive care in some specialties whose actual use will help save resources both in provision and in management of the evacuation procedures. Additionally, with tele-cardiology collaborative service many evacuations can be avoided whereas many cases will be treated and followed locally in Cape Verde with remote technical support from Portugal. This international telemedicine service enabled more efficient evacuations, by reducing expenses in travel and housing, and therefore contributed to the health system's improvement. This study provides some evidence of how important telemedicine really is to cope with both the geography and the shortage of physicians.

By means of the use of the performance evaluation of power system efficiencies (PEPSE) code was modeled the vapor cycle of the nuclear power station of Laguna Verde to reproduce the nuclear plant behavior to conditions of thermal power, licensed at present (2027 MWt); with the purpose of having a base line before the implementation of the project of extended power increase. The model of the gauged vapor cycle to reproduce the nuclear plant conditions makes use of the PEPSE model, design case of the vapor cycle of nuclear power station of Laguna Verde, which has as main components of the model the great equipment of the vapor cycle of Laguna Verde. The design case model makes use of information about the design requirements of each equipment for theoretically calculating the electric power of exit, besides thermodynamic conditions of the vapor cycle in different points. Starting from the design model and making use of data of the vapor cycle measured in the nuclear plant; the adjustment factors were calculated for the different equipment s of the vapor cycle, to reproduce with the PEPSE model the real vapor cycle of Laguna Verde. Once characterized the model of the vapor cycle of Laguna Verde, we can realize different sensibility studies to determine the effects macros to the vapor cycle by the variation of certain key parameters.

Laguna Verde - A photo story

Safety is one of the main factors in the construction and operation of a modern nuclear power plant. There are many barriers between the fission products produced in the fuel elements of the core, and the environment: the cladding of the fuel pins which are enclosed in the reactor core, the pressure vessel containing the core and which in turn is enclosed in the reactor containment, all this being located in a low-pressure secondary containment or reactor building. Despite these precautions, nuclear safety is still a widely-discussed issue. The important fact remains, however, that there has not been a single radiation-induced fatality or serious injury at any civilian nuclear power plant during 20 years of nuclear power generation. This includes the accident that occurred in March 1979 at the Three Mile Island nuclear plant in the USA. A substantial component contributing to safety in a nuclear power plant is the containment. The following photos of Laguna Verde, Mexico's first nuclear power station being constructed at Alta Lucero in Vera Cruz, give an impression of how strong this concrete and steel containment actually is. Laguna Verde consists of two 600 MWe units and the plant is scheduled for commercial operation in 1982. Construction began in 1974. Both units are boiling-water reactors. The photos show, in general, the construction of the primary containment for the reactors (the dry wells). The dry well contains the reactor itself and has two layers: the leak-tight steel liner and the heavy concrete building. The purpose of the primary containment is to retain steam and gases that might escape in an emergency and to direct these through relief tubes to a water pond for cooling. Surrounding this primary containment will be a reactor building which serves as a secondary low-pressure containment, able to operate at pressures up to 0.2 atmospheres.

A 3-year study was undertaken to evaluate the suitability of the available modeling tools for characterizing environmental flows in the middle Verde River watershed of central Arizona, describe riparian vegetation throughout the watershed, and estimate sediment mobilization in the river. Existing data on fish and macroinvertebrates were analyzed in relation to basin characteristics, flow regimes, and microhabitat, and a pilot study was conducted that sampled fish and macroinvertebrates and the microhabitats in which they were found. The sampling for the pilot study took place at five different locations in the middle Verde River watershed. This report presents the results of this 3-year study. The Northern Arizona Groundwater Flow Model (NARGFM) was found to be capable of predicting long-term changes caused by alteration of regional recharge (such as may result from climate variability) and groundwater pumping in gaining, losing, and dry reaches of the major streams in the middle Verde River watershed. Over the period 1910 to 2006, the model simulated an increase in dry reaches, a small increase in reaches losing discharge to the groundwater aquifer, and a concurrent decrease in reaches gaining discharge from groundwater. Although evaluations of the suitability of using the NARGFM and Basin Characteristic Model to characterize various streamflow intervals showed that smallerscale basin monthly runoff could be estimated adequately at locations of interest, monthly stream-flow estimates were found unsatisfactory for determining environmental flows.Orthoimagery and Moderate Resolution Imaging Spectroradiometer data were used to quantify stream and riparian vegetation properties related to biotic habitat. The relative abundance of riparian vegetation varied along the main channel of the Verde River. As would be expected, more upland plant species and fewer lowland species were found in the upper-middle section compared to the lower-middle section, and vice

A Solanum species long considered an American introduction to the Cape Verde Islands off the west coast of Africa is identified as Solanum rigidum, a member of the Eggplant clade of Old World spiny solanums (Solanum subgenus Leptostemonum) and is probably endemic to the Cape Verde Islands. Collections of this species from the Caribbean are likely to have been introduced from the Cape Verde Islands on slave ships. We discuss the complex nomenclatural history of this plant and provide a detailed description, illustration and distribution map. The preliminary conservation status of Solanum rigidum is Least Concern, but needs to be reassessed in light of its endemic rather than introduced status.

Groundwater resources in Cape Verde provide water for agriculture, industry, and human consumption. These resources are limited and susceptible to contamination. Additional groundwater resources are needed for continued agricultural development, particularly during times of drought, but increased use and (or) climatic change may have adverse effects on the quantity and quality of freshwater available. In volcanic island aquifers such as those of Cape Verde, a lens of fresh groundwater typically ?floats? upon a layer of brackish water at the freshwater/saltwater boundary, and increased pumping may cause salt water intrusion or other contamination. A recent U.S. Geological Survey study assessed baseline groundwater conditions in watersheds on three islands of Cape Verde to provide the scientific basis for sustainably developing water resources and minimizing future groundwater depletion and contamination.

A Late Holocene Record of Human Impact in the Tropical Lowlands of the Mexican Gulf Coast: Lago Verde.

Lago Verde is a maar lake (18 36 43 N; 95 20 52 W) located on the Gulf Coast of Mexico in "Los Tuxtlas" region. The area was cover by tropical rain forest and is part of the core area of the earliest Mesoamerican cultures. A 6 m sediment core was obtained in order to document vegetation and lake level history of this area. Lago Verde is a shallow, eutrophic lake (max. 4 m), the natural vegetation has been removed and grasslands with some tropical trees such Bursera grows around the lake. According with the radiocarbon chronology the sequence covers the last 2500 yr BP. At the base of the sequence low abundance of tropical trees is record, with intermediate lake levels. A sudden change in the pollen stratigraphy occurs at ca. 2000 yr BP, with important presence of Poaceae, Ambrosia and Cheno.-Am. along with Zea mays indicating human activity in the area. This is associated with a change in limnological conditions, recording turbid, shallow environments. This pollen signals correlates with dry phases in Yucatan, suggesting that this dry climatic signal probably had effect on an ample area of Mexico. However, at 1200 yr BP, no more Zea mays pollen is recovered suggesting the abandonment of the area. Lake levels recover as well as the tropical forest. The last 150 yr BP is characterized by the reduction in the pollen of tropical forest trees, presence of Zea mays, increased erosion rates, turbidity and eutrophication in the lake, all related to deforestation.

Cape Verde: Marketing Good Governance Kap Verde: Die Vermarktung von Good Governance

Full Text Available Faced with a lack of natural resources Cape Verde has made good governance one of its most marketable products. Running parallel to the institutionalisation of democratic politics there has been an overhaul and growing sophistication in public administration, though certain weaknesses persist. This report argues that it is reform and improvement in this area in particular that has enabled this small island state to punch above its weight and achieve remarkable social, economic and political results. But will the successful formula of the past decade prove sufficient for the future? Poverty and unemployment have by no means been conquered. Much of the economic growth has been based in the tourist sector and the government is well aware of the dangers of over-reliance on a single industry. Cape Verde’s midway location between South America and Europe and its increasing international transport connections will continue to offer advantages to drug traffickers. The next few years of the world financial crisis will show whether marketing good governance is enough and whether this is the model for small resource developing states.

The continental slope current system between Cape Verde and the Canary Islands

Full Text Available We use hydrographic, velocity and drifter data from a cruise carried out in November 2008 to describe the continental slope current system in the upper thermocline (down to 600 m between Cape Verde and the Canary Islands. The major feature in the region is the Cape Verde Frontal Zone (CVFZ, separating waters from tropical (southern and subtropical (northern origin. The CVFZ is found to intersect the slope north of Cape Blanc, between 22°N and 23°N, but we find that southern waters are predominant over the slope as far north as 24°N. South of Cape Blanc (21.25°N the Poleward Undercurrent (PUC is a prominent northward jet (50 km wide, reaching down to 300 m and indistinguishable from the surface Mauritanian Current. North of Cape Blanc the upwelling front is found far offshore, opening a near-slope northward path to the PUC. Nevertheless, the northward PUC transport decreases from 2.8 Sv at 18°N to 1.7 Sv at 24°N, with about 1 Sv recirculating ofshore just south of Cape Blanc, in agreement with the trajectory of subsurface drifters. South of the CVFZ there is an abrupt thermohaline transition at σϴ=26.85 kg m–3, which indicates the lower limit of the relatively pure (low salt and high oxygen content South Atlantic Central Water (SACW variety that coexists with the dominant locally-diluted (salinity increases through mixing with North Atlantic Central Water but oxygen diminishes because of enhanced remineralization Cape Verde (SACWcv variety. At 16°N about 70% of the PUC transport corresponds to the SACW variety but but this is transformed into 40% SACWcv at 24°N. However, between Cape Verde and Cape Blanc and in the 26.85 < σϴ < 27.1 layer, we measure up to 0.8 Sv of SACWcv being transported south. The results strongly endorse the idea that the slope current system plays a major role in tropical-subtropical water-mass exchange.

Patterns of genetic diversity in three plant lineages endemic to the Cape Verde Islands.

Science.gov (United States)

Romeiras, Maria M; Monteiro, Filipa; Duarte, M Cristina; Schaefer, Hanno; Carine, Mark

2015-05-15

Conservation of plant diversity on islands relies on a good knowledge of the taxonomy, distribution and genetic diversity of species. In recent decades, a combination of morphology- and DNA-based approaches has become the standard for investigating island plant lineages and this has led, in some cases, to the discovery of previously overlooked diversity, including 'cryptic species'. The flora of the Cape Verde archipelago in the North Atlantic is currently thought to comprise ∼740 vascular plant species, 92 of them endemics. Despite the fact that it is considered relatively well known, there has been a 12 % increase in the number of endemics in the last two decades. Relatively few of the Cape Verde plant lineages have been included in genetic studies so far and little is known about the patterns of diversification in the archipelago. Here we present an updated list for the endemic Cape Verde flora and analyse diversity patterns for three endemic plant lineages (Cynanchum, Globularia and Umbilicus) based on one nuclear (ITS) and four plastid DNA regions. In all three lineages, we find genetic variation. In Cynanchum, we find two distinct haplotypes with no clear geographical pattern, possibly reflecting different ploidy levels. In Globularia and Umbilicus, differentiation is evident between populations from northern and southern islands. Isolation and drift resulting from the small and fragmented distributions, coupled with the significant distances separating the northern and southern islands, could explain this pattern. Overall, our study suggests that the diversity in the endemic vascular flora of Cape Verde is higher than previously thought and further work is necessary to characterize the flora.

Lopez Jimenez, Jose Francisco

2015-01-01

During the accident occurred in Fukushima Daiichi Nuclear Power Station in Japan, the onsite and offsite electrical systems were affected and lost for a long time with irreversible consequences, therefore, the Mexican Regulatory Body known as the National Commission for Nuclear Safety and Safeguards (CNSNS: for its acronym in Spanish) has taken several actions to review the current capacity of the electrical systems installed at Laguna Verde NPP to cope with an event beyond of the design basis. The first action was to require to Laguna Verde NPP the compliance with Information Notice 2011-05 'Tohoku-Taiheiyou-Oki earthquake effects on Japanese Nuclear Power Plants' and with 10 CFR 50.54 'Conditions of licenses' section 'hh', both documents were issued by the United States Nuclear Regulatory Commission (USNRC). Additionally, CNSNS has taken into account the response actions emitted by other countries after the Fukushima accident. This involved the review of documents generated by Germany, Canada, United Arab Emirates, Finland, France, the United Kingdom and the Western European Nuclear Regulator's Association (WENRA). CNSNS made special inspections to verify the current capacity of the electrical systems of AC and DC. As a result of these inspections, CNSNS issued requirements that must be addressed by Laguna Verde NPP to demonstrate that it has the capacity to cope with events beyond the design basis. Parallel to the above, Mexico has participated in the Ibero-american Forum to address matters related to the 'Resistance Tests', the evaluations of the Forum have reached similar conclusions to those required by European Nuclear Safety Regulators Group (ENSREG), under the format proposed by WENRA. The actions carried out here are closely linked to the requirements established by the USNRC. It is also important to mention that: 1) the Extended Power Up-rate project was implemented in both Units of the Laguna Verde NPP before

At the end of 2009, 21,313 cases of dengue-3 virus (DENV-3) were reported in the islands of Cape Verde, an archipelago located in the Atlantic Ocean 570 km from the coast of western Africa. It was the first dengue outbreak ever reported in Cape Verde. Mosquitoes collected in July 2010 in the city of Praia, on the island of Santiago, were identified morphologically as Aedes aegypti formosus. Using experimental oral infections, we found that this vector showed a moderate ability to transmit the epidemic dengue-3 virus, but was highly susceptible to chikungunya and yellow fever viruses.

This paper is informative of the General Electric Hitachi and Global Nuclear Fuel - Americas are collaboration with Comision Federal de Electricidad in a longevity test of thermocouples as power monitoring devices. The test conclusions will serve for final engineering design in detailing the Automated Fixed In-core Probes for calibration of the Local Power Range Monitors (LPRMs) of the Economic Simplified Boiling Water Reactor. This paper introduces the collaboration description and some recent performance evaluation of the thermocouples that are sensitive to gamma radiation and are known generically as Gamma Thermometers (G T). The G Ts in Laguna Verde 2 are radially located inside six instrumentation tubes in the core and consist of seven thermocouples, four are aligned with the LPRM heights and three are axially located between LPRM heights. The Laguna Verde 2 G T test has become the longest test of thermocouples as power monitoring devices in a BWR industry history and confirms their reliability in terms of time-dependent small noise under steady state reactor conditions and good agreement against Traversing In-core Probes power measurements.

Full Text Available Los abonos orgánicos desde tiempos remotos se han trabajado de diferentes maneras, algunossin ningún tipo de control y manejo adecuado, aun así, son utilizados para conservar y mejorar las condiciones fisicoquímicas y biológicas de los suelos. Los abonos orgánicos proceden de la transformación de residuos orgánicos de origen vegetal y/o animal que generan subproductos como lixiviados, los cuales se convierten en un problema de contaminación al no tener en cuentasu captación como líquidos residuales, ya que una parte se filtra deteriorando y contaminando suelos, aguas libres, aguas subterráneas y otra parte queda expuesta en la superficie ocasionando desprendimiento de CO2 hacia la atmósfera, lo cual acelera el efecto invernadero. Este artículo de investigación pretende determinar el manejo actual de residuos orgánicos de fincas dedicadas a la producción agroecológica y caracterizar la composición de estos lixiviados, a diferencia de los residuos líquidos extraídos del compost convencional. Se analizaron en laboratorio muestras de lixiviados de los dos tipos de compost, con el fin de relacionar los parámetros fisicoquímicos y microbiológicos. Los resultados muestran que el lixiviado agroecológico presenta un mayor índice y diversidad de comunidades microbiológicas. Con relación a las características fisicoquímicas hay mayor concentración de nutrientes y metales pesados en el lixiviado convencional, por lo cual se recomienda evaluarlos antes de su aplicación en campo.

Through the electrical industry history there have been developments of different cleaning methods to avoid the insulators flashover s due to pollution. This paper describes the principal cleaning methods applicable to transformers insulators, emphasizing the high pressure fixed-type live insulator washing method, which was applied for cleaning the insulators of 900 MVA transformer bank of the Laguna Verde power plant localized at the state of Veracruz in Mexico. We propose a transformer insulator cleaning methodology, which identifies the main variables to take into account (the voltage level of the transformers, the pollution level of the insulators, determination of the optimal wash time, the amount of water, the optimal pressure of water jet, the maximum conductivity of the water and the wind velocity), reference values are given for these variables. In addition, we present an economic cost analysis when applying a method of this kind in an electric substation.

El caballero del Verde Gabán: algunas consideraciones desde el epicureísmo y el estoicismo

Josefa Álvarez

2007-12-01

Full Text Available The purpose of this paper is to study the figure of the “Caballero del Verde Gabán” from the perspectives of the stoic and Epicurean philosophic traditions given that these traditions deeply influenced the literatures and thought of the Golden Age. To do so, we search and analyze several greco-roman sources that lead us to determine that although both philosophic traditions converge in the figure of the “Caballero del Verde Gabán” a clear preeminence of the epicurean tradition is evident. In contrast, a clear stoic tradition is clear in the figure of “Don Quijote”. We attempt to show how Cervantes presents the reader with two ways of life at odds with each other at the beginning of a new century; one full of realism and pragmatism in the figure of the “Caballero del Verde Gabán”, the other, “the quijotesco” showing its anachronistic idealism.

Peters, G.

1996-01-01

Framatome Technologies Inc.(FTI) recently completed the steam generator chemical cleanings at the Palo Verde Nuclear Generating Station Units 1, 2 and 3. Over 500,000 gallons of low-level radioactive solvents were generated during these cleanings and were processed on-site. Chemical cleaning solutions containing high concentrations of organic chelating wastes are difficult to reduce in volume using standard technologies. The process that was ultimately used at Palo Verde involved three distinct processing steps: The evaporation step was conducted using FTI's submerged combustion evaporator (SCE) that has also been successfully used at Arkansas Nuclear One - Unit 1, Three Mile Island - Unit 1, and Oconee on similar waste. The polishing step of the distillate used ultrafiltration (UF) and reverse osmosis (RO) technology that was also used extensively by Ontario Hydro to assist in their processing of chemical cleaning solvent. This technology, equipment, and operations personnel were provided by Zenon Environmental, Inc. The concentrate from the evaporator was absorbed with a special open-quotes peat mossclose quotes based media that allowed it to be shipped and buried at the Environcare of Utah facility. This is the first time that this absorption media or burial site has been used for chemical cleaning solvent

Human effects on the hydrologic system of the Verde Valley, central Arizona, 1910–2005 and 2005–2110, using a regional groundwater flow model

Garner, Bradley D.; Pool, D.R.; Tillman, Fred D.; Forbes, Brandon T.

Water budgets were developed for the Verde Valley of central Arizona in order to evaluate the degree to which human stresses have affected the hydrologic system and might affect it in the future. The Verde Valley is a portion of central Arizona wherein concerns have been raised about water availability, particularly perennial base flow of the Verde River. The Northern Arizona Regional Groundwater Flow Model (NARGFM) was used to generate the water budgets and was run in several configurations for the 1910–2005 and 2005–2110 time periods. The resultant water budgets were subtracted from one another in order to quantify the relative changes that were attributable solely to human stresses; human stresses included groundwater withdrawals and incidental and artificial recharge but did not include, for example, human effects on the global climate. Three hypothetical and varied conditions of human stresses were developed and applied to the model for the 2005–2110 period. On the basis of this analysis, human stresses during 1910–2005 were found to have already affected the hydrologic system of the Verde Valley, and human stresses will continue to affect the hydrologic system during 2005–2110. Riparian evapotranspiration decreased and underflow into the Verde Valley increased because of human stresses, and net groundwater discharge to the Verde River in the Verde Valley decreased for the 1910–2005 model runs. The model also showed that base flow at the upstream end of the study area, as of 2005, was about 4,900 acre-feet per year less than it would have been in the absence of human stresses. At the downstream end of the Verde Valley, base flow had been reduced by about 10,000 acre-feet per year by the year 2005 because of human stresses. For the 2005–2110 period, the model showed that base flow at the downstream end of the Verde Valley may decrease by an additional 5,400 to 8,600 acre-feet per year because of past, ongoing, and hypothetical future human

Geotourism and Geoparks in particular are real opportunities to rural developments promoting the rate decline of unemployment and emigration through engaging the local communities in geopark activities and tourism marketing in the form of adventure tourism, ecotourism, rural tourism and health geotourism. Geotourism is closely linked with Medical Geology. The intake of minerals and chemical elements for food, water, soil (through geophagy) or dust can be accomplished by ingestion, inhalation or dermal absorption. Pelotherapy or “Mudtherapy” is the use of mud/clay for therapeutic applications, internal or external. Cape Verde archipelago is located in Atlantic ocean, 400 km westwards of Senegal coast. Geotourism is being developed, mainly focused on the development of a geopark in Fogo island huge caldera, but also trying to take advantage of their potentialities for Geomedecine. A cooperative program established between Cape Verde University (UCV) and Aveiro University (UA, Portugal) is under way, aiming, on a first stage, to identify Geotouristic potentialities and, on a second stage, to develop products. Geotourism is being developed, mainly focused on the development of a geopark in Fogo isl. huge caldera, but also trying to take advantage of their potentialities for Geomedecine.

By means of the use of the performance evaluation of power system efficiencies (PEPSE) code was modeled the vapor cycle of the nuclear power station of Laguna Verde to reproduce the nuclear plant behavior to conditions of thermal power, licensed at present (2027 MWt); with the purpose of having a base line before the implementation of the project of extended power increase. The model of the gauged vapor cycle to reproduce the nuclear plant conditions makes use of the PEPSE model, design case of the vapor cycle of nuclear power station of Laguna Verde, which has as main components of the model the great equipment of the vapor cycle of Laguna Verde. The design case model makes use of information about the design requirements of each equipment for theoretically calculating the electric power of exit, besides thermodynamic conditions of the vapor cycle in different points. Starting from the design model and making use of data of the vapor cycle measured in the nuclear plant; the adjustment factors were calculated for the different equipment s of the vapor cycle, to reproduce with the PEPSE model the real vapor cycle of Laguna Verde. Once characterized the model of the vapor cycle of Laguna Verde, we can realize different sensibility studies to determine the effects macros to the vapor cycle by the variation of certain key parameters.

2013-02-18

In Maio Island, Republic of Cape Verde, a seven-year old mongrel female dog exhibiting severe generalized adenomegaly and a poor body condition was examined during an animal welfare campaign. A blood smear was drawn from peripheral blood collection and several organisms consistent with Dirofilaria immitis microfilariae were identified. Both the antigen test conducted from plasma and the RT-PCR test performed from the blood smear sample were positive for D. immitis. This is, to the best of our knowledge, the first report of D. immitis in Cape Verde. The fact that the dog was autochthonous and had never left the island strongly suggests there might be other animals infected with the parasite. Our finding confirms the existence of the parasite in the canine population and necessarily implies the presence of a competent vector. As a serious cardiopulmonary disease and with the risk of the pathogen spreading rapidly, broader epidemiological studies need to be conducted to determine D. immitis prevalence in the canine population of Maio Island.

Maite, Vázquez-Luis; José M, Guerra-García; Susana, Carvalho; Lydia Png-Gonzalez

2013-01-01

Mantacaprella macaronensis new genus, new species, is described based on specimens collected from Canary Islands and Cape Verde. Mantacaprella is close to the genera Parambus, Pseudolirius, Propodalirius and Paracaprella, but can be distinguished by the combination of the following characteristics: pereopods 3, 4 and 5 two-articulate; pereopods 6 and 7 six-articulate; mandibular molar present and palp absent; male abdomen with a pair of well-developed appendages. The new species has been found living in Cymodocea nodosa meadows and Caulerpa prolifera beds from 8.8 to 14.6 m depth in Gran Canaria (Canary Islands), and in natural rocky and artificial habitats (shipwrecks) at 25 m in Sal Island (Cape Verde). Even though the new species is one of the dominant amphipods inhabiting meadows of Cymodocea nodosa in Gran Canaria and in Cape Verde, it had not been described so far. This reflects the lack of knowledge on Macaronesian invertebrates, such as amphipods, and the need of further taxonomical studies to better characterise the whole biodiversity of this region and to design adequate programmes of management and conservation.

Proposal for implementation of alternative source term in the nuclear power plant of Laguna Verde

International Nuclear Information System (INIS)

Bazan L, A.; Lopez L, M.; Vargas A, A.; Cardenas J, J. B.

2009-10-01

In 2010 the nuclear power plant of Laguna Verde will implement the extended power upbeat in both units of the plant. Agree with methodology of NEDC-33004P-A, (constant pressure power up rate), and the source term of core, for accidents evaluations, were increased in proportion to the ratio of power level. This means that for the case of a design basis accident of loss of coolant an increase of power of 15% originated an increase of 15% in dose to main control room. Using the method of NEDC-33004P-A to extended power upbeat conditions was determined that the dose value to main control room is very near to regulatory limit established by SRP 6.4. By the above and in order to recover the margin, the nuclear power plant of Laguna Verde will calculate an alternative source term following the criteria established in RG 1.183 (alternative radiological source term for evaluating DBA at nuclear power reactor). This approach also have a more realistic dose value using the criterion of 10-CFR-50.67, in addition is predicted to get the benefit of additional operational flexibilities. This paper present the proposal of implementing the alternative source term in Laguna Verde. (Author)

Full Text Available The paper studies the characteristics of the several procedures that might be used to regenerate green table olive fermentation brines with the aim of reusing them in other stages of the elaboration process and specially for the final packaging of these fruits. The reuse may considerably reduce the waste water pollution of the canning industry as brines make up about 80% of the organic pollutant lead of its waste waters. The two most interesting methods are: adsorption with activated carbon, followed by a cross filtration to separate the adsorbent; and ultrafiltration. The former, should be GA activated carbon, which is the most efficient, in a proportion ranging between 5 and 10 g per litre. For the second, a polysulphone 1.000 daltons molecular weight cut membrane at 18 bars pressure should be used. A previous treatment of brines with bentonite (2 g/l, a range of temperatures between 30 and 45°C as well as low suspended solids and polyphenol contents, increases efficiency notably. In principle, an approximate study of costs shows that regenerated brines are obtained, using either of the two procedures, at slightly lower prices than fresh brines prepared from their ingredients.

The nuclear power plant of Laguna Verde located in the Gulf of Mexico, completes in this 2009, nineteen years to produce by nuclear means 4.78% of the electric power that Mexico requires daily. During this time, the Unit 1 has generated more of 88.85 million mega watt-hour and the Unit 2 more of 69.48 million mega watt-hour with an availability average of 83.55%. Derived of their operation cycles, the nuclear power plant has generated (as any other installation of its type) radioactive wastes of low activity that at the moment are temporarily stored in the site. Due to the life cycle of the nuclear power plant, actually has become necessary to begin a project series focused to continue guaranteeing the storage of these wastes, guarantee that is a license requirement for the operation of this nuclear installation before the National Commission of Nuclear Security and Safeguards. The Federal Commission of Electricity beginning a project that allows continue guaranteeing space of sufficient storage for the wastes that the nuclear power plant of Laguna Verde could generate for the rest of its useful life, this project consisted on a process of physical volume reduction of dry solid radioactive wastes denominated super compacting, it has made possible to reduce the volume that these wastes occupy in the temporary storage noted Dry Solid Radioactive Wastes Deposit located inside the site that occupies the nuclear power plant of Laguna Verde. This work presents the super compacting results, as well as a description of the realization of this task until concluding with the super compacting of 5,854 drums with dry solid radioactive waste of low activity. We will enunciate which were the radiological controls that the Department of Radiological Protection of the nuclear power plant of Laguna Verde applied to this work that was realized for first time in Mexico and the nuclear power plant.

Esta investigación se realizó entre febrero y marzo del 2012 en el Centro de Investigaciones Agronómicas, Sabanilla, San José, Costa Rica. Se utilizó un diseño completamente al azar con cuatro repeticiones y ocho plantas por unidad experimental en un arreglo factorial con los factores de dosis (0, 25% y 50% v/v vermicompost:suelo e inoculación (0 y 500 zoosporas por gramo de suelo. Se trasplantaron plántulas de 35 días, que fueron inoculadas dos semanas después del trasplante. La aplicación de vermicompost provocó un aumento significativo del peso fresco foliar y del peso seco foliar y radical; a mayor dosis, mayor fue el incremento. Las plantas de todos los tratamientos que incluyeron inoculación con P. capsici presentaron síntomas de la enfermedad en la raíz. Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

Full Text Available INTRODUCTION: It has been well documented that schizophrenia presents a better clinical course in developing countries. Although there are many epidemiological studies showing this association, little research has been conducted to investigate the local representation systems for schizophrenia in these countries. OBJECTIVES: This study focuses on cultural factors of schizophrenia, namely the local representation systems for the disease, as well as what is locally understood as deviant behavior and its acceptability, and mechanisms of social-cultural insertion or exclusion of patients with schizophrenia in Cape Verde, Africa. METHODS: Randomized open interviews were carried out with the relatives of patients under treatment at the mental health out patient service of the Batista de Sousa Hospital (São Vicente Island between the years 1994 and 1995. Interviews dealt with patients' life histories and disease related to problems, strategies employed by the family to cope with such problems, and comments on the social and family burden. RESULTS: 20 interviews with close relatives of 10 patients were analyzed. The study focused on three main categories explaining schizophrenia: "tired head" (cabeça cansada, "nervous" (nervoso, and supernatural categories (like "sorcery" or "witchcraft". The interviewees expressed their opinions, either explicitly or not, on whether their relatives truly had a disease. CONCLUSION: Characteristics of local categories for schizophrenia found in Cape Verde can be regarded as a less stigmatized way of dealing with the disease. It is reasonable to suppose that the understanding of such cultural factors could lead to better outcomes in the treatment for schizophrenia in this country, and also in others, where similar conditions can be identified.INTRODUÇÃO: Tem sido bem documentado que a esquizofrenia apresenta um melhor curso clínico em países em desenvolvimento.

Full Text Available O chá é uma das bebidas mais consumidas no mundo, vem sendo utilizado pela população como coadjuvante no tratamento da redução de peso, uma vez que aumenta a termogênese e em muitos casos promove a saciedade. O objetivo deste trabalho foi mostrar como as catequinas do chá verde auxiliam no tratamento da obesidade. Foram realizadas buscas por artigos científicos nas bases de dados Science Direct, Google Acadêmico, Scielo, BVS, Medline e Wilson. Os artigos escolhidos foram publicados no período de 2000 a 2014. Observa-se que o tratamento da obesidade envolve necessariamente a reeducação alimentar, o aumento da atividade física e eventualmente, o uso de algumas medicações auxiliares. Outra alternativa, é o uso de fitoterápicos como por exemplo o chá verde. Estudos têm mostrado que este chá, que é obtido pela infusão da erva Camellia sinensis é rico em catequinas, responsáveis na redução de peso, pois promovem a termogênese e aumentam a saciedade. A epigalocatequina (EGCG, é a catequina mais abundante e mais forte do chá verde. É importante ressaltar que o chá usado de maneira inadequada pode causar hepatotoxicidade. O uso do chá associado a um plano alimentar equilibrado pode trazer benefícios à saúde além da perda de peso. Porém os estudos ainda não são conclusivos, sendo necessários mais estudos para que possa confirmar a eficácia do chá verde na obesidade e a quantidade a ser utilizada. Entretanto, a reeducação alimentar, exercício físico continuam sendo os fatores mais importantes no tratamento da obesidade, Onde o consumo de chá verde deve está associado a uma alimentação saudável.

Full Text Available El tema del humano con recurso, enfoque de este trabajo, tiene un papel importantísimo a la hora de transitar de estrategias competitivas hacia estrategias colaborativas, sobre todo cuando se perciben logros ecosocioeconómicos que avanzan hacia la dirección de un desarrollo territorial. Se tiene como hipótesis, que desde el enfoque de los encadenamientos socioproductivos, centrado en el turismo de intereses especiales, es posible comprender y establecer objetivos comunes dentro de actores, organizaciones, emprendimientos y comunidades locales. El objetivo de este artículo es proponer una aproximación teórica sobre el TIE (Turismo de Intereses Especiales sobre las aglomeraciones, sobre los encadenamientos socioproductivos y sobre el enfoque del humano con recurso, para posteriormente relatar los primeros resultados de esta investigación realizada en los cinco municipios que hacen parte del territorio turístico denominado "Patagonia Verde", en el sur de Chile. A partir de la identificación de actores clave, se aplicaron entrevistas a éstos y fichas de caracterización a emprendimientos. Posteriormente se identificaron fortalezas y oportunidades que puedan ser potenciadas a partir de la perspectiva del humano con recurso. A partir de los encadenamientos socioproductivos, contar con individuos conscientes y proactivos dentro de las instituciones y organizaciones en tareas y ejes estratégicos del desarrollo turístico y que compartan con la perspectiva del desarrollo territorial sustentable, es uno de los desafíos que aquí proponemos. Son los sujetos quienes son capaces de generar las condiciones institucionales para otra forma de comprender y actuar en Turismo.

This paper describes the continuous improvement system of nuclear power plant of Laguna Verde and the achievements in implementing the same and additionally two study cases are presents. In February 2009 is noteworthy because the World Association of Nuclear Operators we identified as a learning organization, qualification which shows that the continuous improvement system has matured, and this system will expose as I get to learn to capitalize on our own experiences and external experiences diffused by the nuclear industry. In 2007 the management of nuclear power plants integrates its improvement systems and calls it continuous improvement system and is presented in the same extensive report that won the National Quality Award. This system is made up of 5 subsystems operating individually and are also related 1) human performance; 2) referential comparison or benchmarking; 3) self-assessment; 4) corrective action and 5) external operating experience. Five subsystems that plan, generate, capture, manage, communicate and protect the knowledge generated during the processes execution of nuclear power plant of Laguna Verde, as well as from external sources. The target set in 2007 was to increase the intellectual capital to always give response to meeting the security requirements, but creating a higher value to quality, customer, environment protection and society. In brief each of them, highlighting the objective, expectations management, implementation and some benefits. At the end they will describe two study cases selected to illustrate these cases as the organization learns by their continuous improvement system. (Author)

Every year, billions of tons of eroded mineral soils from the Saharan Desert and the Sahel region, the largest dust source in the world, cross Mediterranean towards Europe, western Asia and the tropical North Atlantic Ocean as far as the Caribbean and South America. Many aspects of the direct and indirect effects of dust on climate are not well understood and the bulk and surface chemistry of the mineral dust particles determines interactions with gaseous and other particle species. The quantification of the magnitude of warming or cooling remains open because of the strong variability of the atmospheric dust burden and the lack of representative data for the spatial and temporal distribution of the dust composition. CV-Dust is a project that aims at provide a detailed data on the size distribution and the size-resolved chemical and mineralogical composition of dust emitted from North Africa using a natural laboratory like Cape Verde. This archipelago is located in an area of massive dust transport from land to ocean, and is thus ideal to set up sampling devices that are able to characterize and quantify dust transported from Africa. Moreover, Cape Verde's future economic prospects depend heavily on the encouragement of tourism, therefore it is essential to elucidate the role of Saharan dust may play in the degradation of Cape Verde air quality. The main objectives of CV-Dust project are: 1) to characterize the chemical and mineralogical composition of dust transported from Africa by setting up an orchestra of aerosol sampling devices in the strategic archipelago of Cape Verde; 2) to identify the sources of particles in Cape Verde by using receptor models; 3) to elucidate the role Saharan dust may play in the degradation of Cape Verde air quality; 4) to model processes governing dust production, transport, interaction with the radiation field and removal from the atmosphere. Here we present part of the data obtained throughout the last year, involving a set of more

Legitimacy and Innovation in Mining: the case of the Oro Verde Program

Directory of Open Access Journals (Sweden)

Mariana Sarmiento

2013-11-01

Full Text Available The paper describes how the Oro Verde Program emerged, and how it has gained recognition as an innovative program that has successfully promoted improved social and environmental practices for small scale miners. The paper describes the local and regional context where the miners from Oro Verde are from, and attempts to explain how it waspossible for two afro-colombian communities, two NGOs and a government agency to find alternative arrangements to overcome the challenges that result from the complexities of the Choco region in Colombia. The paper argues that one factor of success is the interaction among participants to create a Non-State Market Driven Governance System. In the case of the Oro Verde Program, the norms created by the international system surrounding sustainable development were necessary for allowing the NGOs to bring financial resources into the project as well as opening the doors to isolated communities in Choco to an international market that valued sustainably produced products. Similarly, the national policies surrounding Green Markets and the existence of a government research institution, made the certification process possible and legitimate. Finally, having a law that recognized land rights to afro-Colombian communities and the community councils as local authorities, as well as customary laws about natural resource use and access within these territories was key for the viability of the project. All of these organizations, working as a nested governance system, that respected and embraced different but interdependent norms and interests, were key for the consolidation of a NSMD that has resonated throughout the world and that has become an element of some afro-Colombians’ struggle to protect their rights for self-determination.

Full Text Available The television channel number 10 of Fortaleza (current TV Verdes Mares, during the 1960 decade, passed through the ideological filter of the Military Dictatorship, when the channel was taken from its owner and given to the businessman Edson Queiroz. The filter had consequences in the next decade with the channel affiliation to the biggest network broadcasting of the country, the Rede Globo, which was also protected by the Military Regime. Based on those two facts, it is intended to discuss some aspects of the exploration models of communication that occurs in the country since the specified period, emphasizing the ideology transmitted by the TV channel which has the biggest audience ratings in Ceará.

2018-03-15

The Zika virus (ZIKV) outbreak in the island nation of Cabo Verde was of unprecedented magnitude in Africa and the first to be associated with microcephaly in the continent. Using a simple mathematical framework we present a first epidemiological assessment of attack and observation rates from 7,580 ZIKV notified cases and 18 microcephaly reports between July 2015 and May 2016. In line with observations from the Americas and elsewhere, the single-wave Cabo Verdean ZIKV epidemic was characterized by a basic reproductive number of 1.85 (95% CI, 1.5 - 2.2), with overall the attack rate of 51.1% (range 42.1 - 61.1) and observation rate of 2.7% (range 2.29 - 3.33). Current herd-immunity may not be sufficient to prevent future small-to-medium epidemics in Cabo Verde. Together with a small observation rate, these results highlight the need for rapid and integrated epidemiological, molecular and genomic surveillance to tackle forthcoming outbreaks of ZIKV and other arboviruses.

Population genetic data of 12 X chromosomal short tandem repeats markers (DXS10074, DXS10079, DXS10101, DXS10103, DXS10134, DXS10135, DXS10146, DXS10148, DXS7132, DXS7423, DXS8378 and HPRTB) were analysed in 54 females and 95 males of an immigrant population from Cabo Verde living in Lisboa. The obtained results for forensic statistical parameters such as observed heterozigosity, polymorphism information content, power of discrimination and mean exclusion chance, based on single allele frequencies, reveal that this multiplex system is highly informative and can represent an important tool for genetic identification purposes in the immigrant population of Cabo Verde. Since the studied short tandem repeats genetic markers are distributed on four linkage groups, that can provide independent genotype information, we studied those groups as haploytes. The forensic efficiency parameters for the linked groups were all higher than 0.97, with linkage group I being the most polymorphic and linkage group III the less informative.

Com o objetivo de avaliar a produção e o estado nutricional da cultura de milho sob cultivo intercalar com adubos verdes, foi realizado, entre 1995 e 1997, um experimento em campo, em Piracicaba (SP, em um Litossolo Vermelho eutrófico. O milho foi semeado no espaçamento de 0,90m nas entrelinhas, perfazendo aproximadamente 50.000plantas por hectare. Os tratamentos constaram de uma testemunha, sem cultivo intercalar, e quatro espécies de adubos verdes: mucuna anã (Mucuna deeringiana (Bort. Merr, guandu anão (Cajanus cajan (L. Millsp, crotalária (Crotalaria spectabilis Roth e feijão-de-porco (Canavalia ensiformis (L. DC., semeados sem adubação, no meio da entrelinha, distante 45cm da linha do milho, em duas épocas: simultânea à semeadura do milho e 30dias após. O solo, no primeiro ano, foi preparado sob sistema convencional e, no segundo, cultivaram-se as culturas sob semeadura direta. O delineamento experimental foi de blocos ao acaso com parcelas subdivididas e quatro repetições. O estado nutricional e a produção de grãos do milho apresentaram melhores resultados no cultivo consorciado com feijão-de-porco. Os efeitos positivos desta espécie na produtividade de grãos de milho foram mais acentuados no segundo ano de adoção do cultivo consorciado, quando o sistema de manejo do solo foi semeadura direta. A semeadura dos adubos verdes simultânea ao milho foi o manejo mais recomendável, por não prejudicar o desenvolvimento do milho e reduzir a operação pós-plantio.

Full Text Available Atualmente o Brasil é o maior produtor de coco verde, com uma área plantada equivalente a 57 mil hectares, onde a maior parte da parte da produção (66,5% se concentra na região Nordeste. O descarte do coco depois do consumo da água representa um problema para os sistemas de coleta e tratamento de lixo, pela sua lenta degradação devido ao alto teor de fibras. Neste trabalho são mostrados os resultados da pirólise lenta da fibra e da casca do coco verde. Os experimentos foram conduzidos em um forno experimental de pequena capacidade, a uma temperatura de 350°C. Os resultados mostraram que o rendimento em carbono fixo foi de 74,43% para o endocarpo verde e 58,07% para o mesocarpo verde. O teor de cinzas, para as mesmas amostras, foi de 14,13% e 13,03%, respectivamente. Os teores de voláteis foram de 11,40% para o carvão obtido do endocarpo verde e, de 28,90% para o carvão obtido do mesocarpo verde. Ficou demonstrado que o resíduo do coco verde apresenta potencial para a produção de carvão vegetal.

Se muestrearon 21 parcelas de 1ha cada una, estableciendo tres parcelas por comunidad, también se entrevistaron a pobladores para determinar la relación de éstos con las especies en estudio. En las parcelas muestreadas, se contabilizaron un total de 93 árboles de almendro con Diámetro a la Altura del Pecho (DAP’s ≥70cm, lo que representa una densidad promedio de 4.4 almendros/ha. También, se identificaron posibles amenazas para las especies en estudio y su particularidad con las comunidades y grupos étnicos. Resultados de Modelos Lineales Generalizados (GLM y análisis de correlación, indican que en la zona de estudio, no es el tamaño o diámetro de los almendros lo que mantiene poblaciones de lapas, sino que influyen mucho la densidad de individuos con DAP≥70cm, el nivel de aislamiento de la comunidad y la cantidad y tipo de usos que le dan los pobladores al árbol.

Forty-one water samples were collected and analyzed from throughout the Verde Valley watershed to identify the source of As in well water used for domestic and agricultural purposes. Each water sample was analyzed for anions, cations and trace chemical constituents by atomic absorption spectroscopy, anion chromatography and traditional wet chemical procedures. Arsenic concentrations ranged from 10 to 210 {mu}g/l, with the highest values observed for water pooled on tailings from an abandoned Cu mine. Geostatistical analysis of the data revealed the primary source of As to be groundwater in contact with the Supai and Verde formations, as opposed to runoff from the abandoned mine tailings. Montezuma Well, a collapsed travertine spring, contained the highest levels of naturally occurring As (> 100 {mu}g/l). Arsenic in Montezuma Well water was shown to be 100% arsenate. X-ray absorbance near edge spectra (XANES) of Potomogeton illinoiensis, an endemic plant species of Montezuma Well, demonstrate that As is absorbed as arsenate, reduced to arsenite in the plant and retained as an organic glutathione complex. XANES spectra of Montezuma Well sediments show 4 forms of As present: arsenate ({approx}54%), As(III)-glutathione complex ({approx}32%) and an As-organic complex ({approx}14%) containing dimethylarsinic acid and arsenobetaine. This is the first report of As(III)-glutathione in sediments.

2013-02-01

The verde plant bug, Creontiades signatus (Distant), has been present in south Texas for several years but has more recently been documented as an economic threat to cultivated cotton, (Gossypium hirsutum L. Our studies over 2 yr (2009 and 2010) and two locations (Weslaco and Corpus Christi, TX) investigated feeding-injury of the verde plant bug to a range of cotton boll age classes defined by boll diameter and accumulated degree-days (anthesis to the time of infesting) for first-position cotton bolls infested with the plant bugs. The most detrimental damage to younger cotton holls from verde plant bug feeding was boll abscission. Cotton bolls verde plant bug injured bolls compared with the controls up to 162 ACDD or a mean boll diameter 2.0 cm. Cotton seed weights were significantly reduced up to 179 ACDD or a boll diameter of 2.0 cm at Weslaco in 2009, and up to 317 ACDD or boll diameter 2.6 cm for Weslaco in 2010 when compared with the noninfested controls. Lint weight per cotton boll for infested and noninfested bolls was significantly reduced up to 262 ACDD or boll diameter 2.5 for Corpus Christi in 2010 and up to 288 ACCD or boll diameter 2.6 cm for Weslaco, TX, in 2010. Damage ratings (dependant variable) regressed against infested and noninfested seed-cotton weights showed that in every instance, the infested cotton bolls had a strong and significant relationship with damage ratings for all age classes of bolls. Damage ratings for the infested cotton bolls that did not abscise by harvest showed visual signs of verde plant bug feeding injury and the subsequent development ofboll rot; however, these two forms of injury causing lint and seed mass loss are hard to differentiate from open or boll-locked cotton bolls. Based on the results of both lint and seed loss over 2 yr and four studies cotton bolls should be protected up to approximately 300 ACDD or a boll diameter of 2.5 cm. This equilibrates to bolls that are 12-14 d of age dependent upon daily maximum

Full Text Available A partir de 1997 en Tucumán, R. Argentina, entre el 65% y el 85% de la caña destinada a la producción de azúcar se cosecha en verde o quemada, mediante el sistema de cosecha integral. El resto del cultivo se cosecha en forma semimecánica, con un predominio del uso de la quema, del corte manual y carguío mecánico. La quema de caña, antes o después de ser cosechada, se realiza para remover las hojas adheridas a sus tallos, minimizando así el ingreso de no azúcares a la fábrica. Desde el año 2005, debido a disposiciones legislativas, la cosecha de caña en verde fue aumentando gradualmente, lo que incrementó considerablemente la concentración de compuestos no azúcares en el proceso de elaboración de azúcar. Por ello se decidió evaluar los principales componentes azúcares y no azúcares, especialmente los formadores de color, y su influencia en el proceso fabril de las cuatro variedades comerciales más difundidas en la provincia: TUCCP 77-42, LCP 85-384, CP 65-357 y RA 87-3, cosechadas de tres maneras diferentes: tallo molible limpio, despuntado y sin hojas; caña quemada para eliminar las hojas y despuntada y caña cosechada en verde, con un 15% de "trash" (hojas y despunte aproximadamente. En este trabajo se presentan los datos obtenidos con cosecha en verde y quemada. Los resultados mostraron que la variedad LCP 85-384 es la que presentó el mejor comportamiento para la producción de azúcar, por su mayor contenido de este sacárido y menores tenores de fibra y compuestos no azúcares, independientemente del tipo de cosecha. En las cuatro variedades estudiadas, disminuyeron la extracción de jugo y la cantidad de azúcar recuperable en fábrica y se incrementaron los contenidos de compuestos no azúcares, principalmente almidón y cenizas, cuando se trabajó con caña cosechada en verde.Since 1997 in Tucumán, Argentina, between 65% and 85% of cane for sugar production has been harvested mechanically, either green or burnt

A new digital Cerenkov viewing device (DCVD) with high ultraviolet light sensitivity has been developed. Field measurements on BWR spent fuel at Laguna Verde Nuclear Power Plant Unit 2 resulted in new Cerenkov information on GE9 and GE12 spent fuel assemblies. Off-alignment measurements show: quantitative differences in the degree of light collimation from between the fuel rods; lack of light collimation from water rods; and decreased light collimation from partial length rod positions. Hidden rods could also be detected in off-angle views. The results indicate that it may be possible to detect missing partial-length fuel rods in GE12 fuel assemblies. The new DCVD was able to verify low burnup, long-cooled, natural uranium GE6 fuel assemblies

According to World Health Organization (WHO) estimates, the under-reporting rate for tuberculosis (TB) in Cape Verde between 2006 and 2012 was 49%. However, the WHO recognises the challenges associated with this estimation process and recommends implementing other methods, such as record linkage, to combat TB under-reporting. To estimate and analyse under-reporting of cases by TB surveillance health units and to evaluate TB cases retrieved from other TB diagnostic sources in Praia, Cape Verde, from 2006 to 2012. This cross-sectional study evaluated under-reporting using the following data: 1) the under-reporting index from TB reporting health units (RHUs), where the number of validated TB cases from RHUs was compared with data from the National Programme for the Fight against Tuberculosis and Leprosy (NPFTL); and 2) the under-reporting index among overall data sources, or a comparison of the number of all validated TB cases from all sources with NPFTL data. The TB under-reporting rate was 40% in Praia during the study period, and results were influenced by laboratory findings. The TB under-reporting rate was very similar to the rate estimated by the WHO. TB surveillance must be improved to reduce under-reporting.

From an ethnographic study made at an institution of child protection, located on Yeu island (France, it offers some counterpoints between these two ethnographic contexts, on the Boa Vista and Yeu islands. Therefore, insularity, child mobility and rights of the child are issues addressed at the intersection of studies on kinship and anthropology of childhood. This exercise highlights the relative social isolation that brings families called "single-parent in difficulty" to the institution on Yeu island, in contrast to the abundance of relationships in which child mobility is central to the dynamics of kinship and relatedness on Boa Vista island.

Malaria, despite being preventable and treatable, continues to be a major public health problem worldwide. The archipelago nation of Cape Verde is in a malaria pre-elimination phase with the highest potential to achieve the target goal of elimination in 2020. Nationwide malaria epidemiological data were obtained from the Cape Verde health information system that includes the individual malaria case notification system from all of the country's health structures. Each case is reported to the surveillance service then to the National Malaria Control Programme, which allowed for compilation in the national malaria case database. The database was analysed to assess the origin of the malaria cases, and incidence was calculated from 2010 to 2016 by sex and age. The health centre, health district and month of diagnosis were evaluated, as well as the sex and the age of the patients, allowing a direct descriptive analysis of national data to provide an up-to-date malaria epidemiological profile of the country. Malaria cases were classified as imported or indigenous, and then, geographical analyses were performed using a unique Geographical National Code with Quantum Geographic Information System 2.16.2 software to map the cases by municipalities. The overall temporal evolution of cases was analysed to assess their monthly and yearly variations from 2010 to 2016. Malaria is unstable in Cape Verde, with inter-annual variation and the majority of infections occurring in adult males (> 20 years). The indigenous cases are restricted to Santiago (96%) and Boavista (4%), while imported cases were recorded in all the nine inhabited islands, originating from neighbouring countries with ongoing malaria transmission; from Lusophone countries (25% from Angola, 25% from Guinea-Bissau), followed by the Republic of Senegal (12%) and Equatorial Guinea (10%). In 2010-2012, more imported (93 cases) than indigenous cases (26 cases) were observed; conversely, in 2013 and 2014, more

Full Text Available The horticulture production units in the Green Belt of Gran Rosario appeared in a space traditionally used to the exportable agricultural production. Presents since the XIXth century in the area, they were growing in function of the demographic growth to the first half of 1970 approximately, when the international prices paid for the soya made this leguminous a great competitor for land. The increasing of agricultural production implied an excessive pressure over the natural environment of the rural spaces, like an alteration of the working and living conditions of the people related to this territory. This work wonders about the modifications that happened in the local social horticultural structure in the last thirty years.Las unidades de producción hortícola del Cinturón Verde del Gran Rosario surgen en un espacio tradicionalmente priorizado para la producción agropecuaria exportable. Presentes desde el siglo XIX en el área, fueron incrementándose en función del crecimiento demográfico hasta aproximadamente mediados de la década de 1970, cuando los precios internacionales pagados por la soja convirtieron a esta leguminosa en una ventajosa competidora por tierra. El incremento de la producción agrícola implicó una presión excesiva sobre el entorno natural de los espacios rurales, como una alteración de las condiciones de trabajo y de vida de las personas vinculadas a este territorio.

Once a plant is constructed, there is often insufficient information from the reactor designer or the architect/engineer to properly support operations, especially changes to the plant. In many cases utilities do not know the design bases for their units. As a result of these concerns, many utilities have been searching for ways to define the appropriate design bases for their plant. This paper discusses steps taken by Palo Verde to produce a design bases document and how it is being used to support the operation of the three nuclear units

The vessel of a nuclear reactor is one of the safety barriers more important in the design, construction and operation of the reactor. If the vessel results affected to the grade of to have fracture and/or cracks it is very probable the conclusion of their useful life in order to guarantee the nuclear safety and the radiological protection of the exposure occupational personnel, of the public and the environment avoiding the exposition to radioactive sources. The materials of the vessel of a nuclear reactor are exposed continually to the neutronic irradiation that generates the same nuclear reactor. The neutrons that impact to the vessel have the sufficient energy to penetrate certain depth in function of the energy of the incident neutron until reaching the repose or to be absorbed by some nucleus. In the course of their penetration, the neutrons interact with the nuclei, atoms, molecules and with the same crystalline nets of the vessel material producing vacuums, interstitial, precipitate and segregations among other defects that can modify the mechanical properties of the steel. The steel A533-B is the material with which is manufactured the vessel of the nuclear reactors of nuclear power plant of Laguna Verde, is an alloy that, among other components, it contains atoms of Ni that if they are segregated by the neutrons impact this would favor to the cracking of the same vessel. This work is part of an investigation to analyze the micro-structural damages of the reactor vessels of the nuclear power plant of Laguna Verde due to the neutronic irradiation which is exposed in a continuous way. We will show the characterization of the design steel of the vessel, what offers a comprehension about their chemical composition, the superficial topography and the crystalline nets of the steel A533-B. It will also allow analyze the existence of precipitates, segregates, the type of crystalline net and the distances inter-plains of the design steel of the vessel. (Author)

The project of extended increase of power responds to a necessity of electrical energy in the country, increasing the thermal exit of the reactors of the nuclear power plant of Laguna Verde of 2027 MWt to 2317 MWt. In order to support this transition, changes will make in the configuration of the reactor core and in the operation strategies of the cycle, also they will take initiatives to optimize the economy in fuel cycle. At present in both reactors of the nuclear plant of Laguna Verde fuel GE12 is used. The fuel GE14 presents displays with respect to the GE12, some improvements in the mechanical design and consequently in its performance generally. Between these improvements we can mention: 1. Spacers of high performance. 2. Shielding with barrier. 3. Filter for sweepings {sup d}ebris{sup a}nd 4. Fuel rods of minor partial length. The management of nuclear power plants has decided to introduce the use of fuel GE14 in Laguna Verde in the reload 14 for Unit 1 and of the reload 10 for Unit 2. The process of new introduction fuel GE14 consists of two stages, first consists on subjecting the one new design of fuel to the regulator organism in the USA: Nuclear Regulatory Commission, in Mexico the design must be analyzed and authorized by the National Commission of Nuclear Safety and Safeguards, for its approval of generic form, by means of the demonstration of the fulfillment with the amendment 22 of GESTAR II, the second stage includes the specific analyses of plant to justify the use of the new fuel design in a reload core. The nuclear plant of Laguna Verde would use some of the results of the security analyses that have been realized for the project of extended increase of power with fuel GE14, to document the specific analyses of plant with the new fuel design. The result of the analyses indicates that the reload lots are increased of 116-120 assemblies in present conditions (2027 MWt) to 140-148 assemblies in conditions of extended increase of power (2317 MWt

Verde plant bugs, Creontiades signatus Distant (Hemiptera: Miridae), were released onto caged cotton, Cossypium hirsutum L., for a 1-wk period to characterize the effects of insect density and bloom period of infestation on cotton injury and yield in 2011 and 2012, Corpus Christi, TX. When plants were infested during early bloom (10-11 nodes above first white flower), a linear decline in fruit retention and boll load and a linear increase in boll injury were detected as verde plant bug infestation levels increased from an average of 0.5 to 4 bugs per plant. Lint and seed yield per plant showed a corresponding decline. Fruit retention, boll load, and yield were not affected on plants infested 1 wk later at peak bloom (8-9 nodes above first white flower), even though boll injury increased as infestation levels increased. Second-year testing verified boll injury but not yield loss, when infestations occurred at peak bloom. Incidence of cotton boll rot, known to be associated with verde plant bug feeding, was low to modest (verde plant bug were important contributors to yield decline, damage potential was greatest during the early bloom period of infestation, and a simple linear response best described the yield response-insect density relationship at early bloom. Confirmation that cotton after peak bloom was less prone to verde plant bug injury and an early bloom-specific economic injury level were key findings that can improve integrated pest management decision-making for dryland cotton, at least under low-rainfall growing conditions.

Beisner, Kimberly R.; Paretti, Nicholas V.; Tucci, Rachel S.

Stable isotope delta values (δ18O and δ2H) of precipitation can vary with elevation, and quantification of the precipitation elevation gradient can be used to predict recharge elevation within a watershed. Precipitation samples were analyzed for stable isotope delta values between 2003 and 2014 from the Verde River watershed of north-central Arizona. Results indicate a significant decrease in summer isotopic values overtime at 3,100-, 4,100-, 6,100-, 7,100-, and 8,100-feet elevation. The updated local meteoric water line for the area is δ2H = 7.11 δ18O + 3.40. Equations to predict stable isotopic values based on elevation were updated from previous publications in Blasch and others (2006), Blasch and Bryson (2007), and Bryson and others (2007). New equations were separated for samples from the Camp Verde to Flagstaff transect and the Prescott to Chino Valley transect. For the Camp Verde to Flagstaff transect, the new equations for winter precipitation are δ18O = -0.0004z − 8.87 and δ2H = -0.0029z − 59.8 (where z represents elevation in feet) and the summer precipitation equations were not statistically significant. For the Prescott to Chino Valley transect, the new equations for summer precipitation are δ18O = -0.0005z − 3.22 and δ2H = -0.0022z − 27.9; the winter precipitation equations were not statistically significant and, notably, stable isotope values were similar across all elevations. Interpretation of elevation of recharge contributing to surface and groundwaters in the Verde River watershed using the updated equations for the Camp Verde to Flagstaff transect will give lower elevation values compared with interpretations presented in the previous studies. For waters in the Prescott and Chino Valley area, more information is needed to understand local controls on stable isotope values related to elevation.

Auxiliary feedwater system risk-based inspection guide for the Palo Verde Nuclear Power Plant

International Nuclear Information System (INIS)

Bumgardner, J.D.; Moffitt, N.E.; Gore, B.F.; Vo, T.V.; Sloan, J.A.

1993-02-01

In a study sponsored by the US Nuclear Regulatory Commission (NRC), Pacific Northwest Laboratory has developed and applied a methodology for deriving plant-specific risk-based inspection guidance for the auxiliary feedwater (AFW) system at pressurized water reactors that have not undergone probabilistic risk assessment (PRA). This methodology uses existing PRA results and plant operating experience information. Existing PRA-based inspection guidance information recently developed for the NRC for various plants was used to identify generic component failure modes. This information was then combined with plant-specific and industry-wide component information and failure data to identify failure modes and failure mechanisms for the AFW system at the selected plants. Palo Verde was selected as one of a series of plants for study. The product of this effort is a prioritized listing of AFW failures which have occurred at the plant and at other PWRs. This listing is intended for use by NRC inspectors in the preparation of inspection plans addressing AFW risk-important components at the Palo Verde plants

In this work the main results of the simulation of overpressure events are presented using a model of the nuclear power plant of Laguna Verde developed for the RELAP/SCDAPSIM code. As starting point we have the conformation of a Laguna Verde model that represents a stationary state to similar conditions to the operation of the power station with Extended Power Up rate (EPU). The transitory of simulated pressure are compared with those documented in the Final Safety Analysis Report of Laguna Verde (FSAR). The results of the turbine shot transitory with and without by-pass of the main turbine are showed, and the event of closes of all the valves of main vapor isolation. A preliminary simulation was made and with base in the results some adjustments were made for the operation with EPU, taking into account the Operation Technical Specifications of the power station. The results of the final simulations were compared and analyzed with the content in the FSAR. The response of the power station to the transitory, reflected in the model for RELAP, was satisfactory. Finally, comments about the improvement of the model are included, for example, the response time of the protection and mitigation systems of the power station. (Author)

Tube structural integrity evaluation of Palo Verde Unit 1 steam generators for axial upper-bundle cracking

International Nuclear Information System (INIS)

Woodman, B.W.; Begley, J.A.; Brown, S.D.; Sweeney, K.; Radspinner, M.; Melton, M.

1995-01-01

The analysis of the issue of upper bundle axial ODSCC as it apples to steam generator tube structural integrity in Unit 1 at the Palo Verde Nuclear generating Station is presented in this study. Based on past inspection results for Units 2 and 3 at Palo Verde, the detection of secondary side stress corrosion cracks in the upper bundle region of Unit 1 may occur at some future date. The following discussion provides a description and analysis of the probability of axial ODSCC in Unit 1 leading to the exceedance of Regulatory Guide 1.121 structural limits. The probabilities of structural limit exceedance are estimated as function of run time using a conservative approach. The chosen approach models the historical development of cracks, crack growth, detection of cracks and subsequent removal from service and the initiation and growth of new cracks during a given cycle of operation. Past performance of all Palo Verde Units as well as the historical performance of other steam generators was considered in the development of cracking statistics for application to Unit 1. Data in the literature and Unit 2 pulled tube examination results were used to construct probability of detection curves for the detection of axial IGSCC/IGA using an MRPC (multi-frequency rotating panake coil) eddy current probe. Crack growth rates were estimated from Unit 2 eddy current inspection data combined with pulled tube examination results and data in the literature. A Monte-Carlo probabilistic model is developed to provide an overall assessment of the risk of Regulatory Guide exceedance during plant operation

The planning of performances in radiological emergencies, with the object of reducing the consequences as much as possible on the population to accidental liberations of radioactive material coming from Nuclear power plant, it has been of main interest in the nuclear community in the world. In Mexico it has not been the exception, since with the setting in march of the Laguna Verde nuclear power plant exists an executive program of planning for emergencies that it outlines the activities to follow trending to mitigate the consequences that are derived of this emergency. As integral part of this program this the External Plan of Radiological Emergency (PERE) that covers the emergencies that could leave the frontiers of the Laguna Verde power plant. In the PERE it settles down the planning, address and control of the preparation activities, response and recovery in emergencies, as well as the organization and coordination of the institutions that participate. The National Institute of Nuclear Research (ININ), like integral part of these institutions in the PERE, has an infrastructure that it allows to participate in the plan in a direct way in the activities of 'Control of the radiological exhibition the response personnel and control of water and foods' and of support way and consultant ship in the activities of 'Monitoring, Classification and decontamination of having evaluated' and 'Specialized medical radiological attention'. At the moment the ININ has a radiological mobile unit and this conditioning a second mobile unit to carry out part of the activities before mentioned; also accounts with 48 properly qualified people that directly intervene in the plan. In order to guarantee an adequate response in the PERE an organization it has been structured like that of the annex as for the personnel, transport, team, procedures and communication system, with the objective always of guaranteeing the security and the population's health in emergency situations in the

Full Text Available El reciente Libro Verde sobre reagrupación familiar, se centra en una serie de preguntas derivadas todas ellas de la aplicación de la Directiva 2003/86/CE, y en el que se invitaba a todas las partes interesadas a responder hasta el pasado 1 de marzo de 2012 a cualquiera de las 14 cuestiones planteadas en relación a la reunificación familiar de los nacionales de terceros países que residen legalmente en la Unión Europea. Con esta iniciativa, se ha impulsado un debate público sobre el tema de la reunificación familiar con el objetivo de determinar si es necesario o no, realizar un seguimiento más concreto de esta política. En este contexto, el Libro Verde hoy adoptado pretende recoger las opiniones de las partes interesadas y de los Estados miembros sobre una serie de interrogantes surgidos en este ámbito de tal forma que sus aportaciones supongan un conocimiento más exacto de la realidad de la reagrupación familiar en sus respectivos países, además de poder alcanzar una mejora con la que se pueda garantizar una aplicación mucho más eficaz del régimen de reagrupación familiar a escala de la Unión Europea. No obstante, cualquier posible método de seguimiento ha de ser objeto de una evaluación en profundidad de su impacto sobre los derechos fundamentales, en particular el respeto de la vida privada y familiar, el derecho a contraer matrimonio, los derechos del menor y el principio de no discriminación

Chemistry of volcanic soils used for agriculture in Brava Island (Cape Verde)

Brava is a small volcanic island located on the south-western part of the Cape Verde archipelago. It is characterized by an irregular plateau between 300 and 976 m above sea level, which is bounded by steep coastal cliffs and cut by fluvial incision in a generally radial drainage pattern. The major volcano-stratigraphic units of the island are: Lower Unit, Middle Unit, Upper Unit, and Sediments. Although Brava is one of the islands with more frequent rainy periods in Cape Verde, the climate is essentially semi-arid, which associated with the rough topography leads to incipient soils. Detailed Fe speciation and chemical composition studies of Cape Verde soils have shown that oxidation is a major weathering mechanism, and high contents of trace elements may occur originated from imbalance of elements in the volcanic parent materials, which can be a threat to the environmental health. The soils mostly used for agriculture in Brava Island are those developed on phonolitic pyroclasts on the plateau and also on sediments. In this work the whole sample (< 2 mm) and the clay-sized fraction (< 2 µm) of these soils were analysed by Mössbauer spectroscopy and neutron activation analysis, aiming to characterize the iron speciation and to determine the concentration and distribution of 30 chemical elements in Brava soils. Mössbauer spectroscopy shows that Fe is more oxidyzed in topsoils developed on sediments (84-87%) than in soils developed on pyroclasts (71-79%). In the clay sized-fraction of all the studied soils only Fe(III) was detected. Iron oxides clearly distinguish the soils derived from the two types of parent materials, hematite being the only Fe oxide present in soils developed on sediments, while maghemite is more abundant in soils developed on pyroclasts. Iron and chromium are depleted in this fine fraction suggesting their occurrence as iron oxides and ferromagnesian minerals present in coarser particles. Among the chemical elements studied, antimony was found

Large Marine Ecosystems such as the Canary Current system off West Africa sustains high abundance of small pelagic prey, which attracts marine predators. Seabirds are top predators often used as biodiversity surrogates and sentinel species of the marine ecosystem health, thus frequently informing marine conservation planning. This study presents the first data on the spatial (GPS-loggers) and trophic (stable isotope analysis) ecology of a tropical seabird-the endangered Cape Verde shearwater Calonectris edwardsii-during both the incubation and the chick-rearing periods of two consecutive years. This information was related with marine environmental predictors (species distribution models), existent areas of conservation concern for seabirds (i.e. marine Important Bird Areas; marine IBAs) and threats to the marine environment in the West African areas heavily used by the shearwaters. There was an apparent inter-annual consistency on the spatial, foraging and trophic ecology of Cape Verde shearwater, but a strong alteration on the foraging strategies of adult breeders among breeding phases (i.e. from incubation to chick-rearing). During incubation, birds mostly targeted a discrete region off West Africa, known by its enhanced productivity profile and thus also highly exploited by international industrial fishery fleets. When chick-rearing, adults exploited the comparatively less productive tropical environment within the islands of Cape Verde, at relatively close distance from their breeding colony. The species enlarged its trophic niche and increased the trophic level of their prey from incubation to chick-rearing, likely to provision their chicks with a more diversified and better quality diet. There was a high overlap between the Cape Verde shearwaters foraging areas with those of European shearwater species that overwinter in this area and known areas of megafauna bycatch off West Africa, but very little overlap with existing Marine Important Bird Areas.

Surficial Geologic Map of Mesa Verde National Park, Montezuma County, Colorado

Science.gov (United States)

Carrara, Paul E.

2012-01-01

Mesa Verde National Park in southwestern Colorado was established in 1906 to preserve and protect the artifacts and dwelling sites, including the famous cliff dwellings, of the Ancestral Puebloan people who lived in the area from about A.D. 550 to A.D. 1300. In 1978, the United Nations designated the park as a World Heritage Site. The geology of the park played a key role in the lives of these ancient people. For example, the numerous (approximately 600) cliff dwellings are closely associated with the Cliff House Sandstone of Late Cretaceous age, which weathers to form deep alcoves. In addition, the ancient people farmed the thick, red loess (wind-blown dust) deposits on the mesa tops, which because of its particle size distribution has good moisture retention properties. The soil in this loess cover and the seasonal rains allowed these people to grow their crops (corn, beans, and squash) on the broad mesa tops. Today, geology is still an important concern in the Mesa Verde area because the landscape is susceptible to various forms of mass movement (landslides, debris flows, rockfalls), swelling soils, and flash floods that affect the park's archeological sites and its infrastructure (roads, septic systems, utilities, and building sites). The map, which encompasses an area of about 100 mi2 (260 km2), includes all of Mesa Verde National Park, a small part of the Ute Mountain Indian Reservation that borders the park on its southern and western sides, and some Bureau of Land Management and privately owned land to the north and east. Surficial deposits depicted on the map include: artificial fills, alluvium of small ephemeral streams, alluvium deposited by the Mancos River, residual gravel on high mesas, a combination of alluvial and colluvial deposits, fan deposits, colluvial deposits derived from the Menefee Formation, colluvial deposits derived from the Mancos Shale, rockfall deposits, debris flow deposits, earthflow deposits, translational and rotational landslide

Waskey, D.

2015-01-01

The 61 BMI (Bottom Mount Instrumentation) nozzles of the unit 3 of the Palo Verde plant have been examined through ASME Code Case N722. The nozzle 3 was the only one with leakage noted. The ultrasound testing results are characteristic of PWSCC (Primary Water Stress Corrosion Cracking). The initiation likely occurred at a weld defect which was exposed to the primary water environment resulting in PWSCC. All other nozzles (60) showed no unacceptable indications. Concerning nozzle 3 one crack in J-groove weld connected large defect to primary water. An environmental model has been used to simulate and optimize the repair. The AREVA crew was on site 18 days after contract award and the job was completed in 12 days, 30 hours ahead of baseline schedule. This series of slides describes the examination of the BMI nozzles, the repair steps, and alternative design concepts

Leptospirosis is an important worldwide zoonotic disease that can infect both animals and humans. In most cases, leptospirosis is a nonspecific self-limiting illness, but some patients can develop a severe form with a high mortality. This study was carried out in Santiago Island, Cape Verde, in 2012-2013. A total of 62 wild rodents (Rattus rattus and Mus domesticus) were analyzed. The lipL32 gene, present only in pathogenic Leptospira spp., was amplified by PCR, and 16 samples were positive (25.8%). In both rodent species, Leptospira interrogans was identified. The results show the presence of pathogenic Leptospira in the three localities analyzed in Santiago. The presence of L. interrogans demonstrates a serious health risk for the population, since this species has been associated with the most severe form of leptospirosis, the Weil's disease in humans, a severe infection with jaundice, renal failure, and hemorrhage.

The Cape Verde islands are part of the African Sahelian arid belt that possesses an erratic rain pattern prompting the need for water reservoirs, which are now critical for the country’s sustainability. Worldwide, freshwater cyanobacterial blooms are increasing in frequency due to global climate change and the eutrophication of water bodies, particularly in reservoirs. To date, there have been no risk assessments of cyanobacterial toxin production in these man-made structures. We evaluated this potential risk using 16S rRNA gene amplicon sequencing and full metagenome sequencing in freshwater reservoirs of Cape Verde. Our analysis revealed the presence of several potentially toxic cyanobacterial genera in all sampled reservoirs. Faveta potentially toxic and bloom-forming Microcystis sp., dominated our samples, while a Cryptomonas green algae and Gammaproteobacteria dominated Saquinho and Poilão reservoirs. We reconstructed and assembled the Microcystis genome, extracted from the metagenome of bulk DNA from Faveta water. Phylogenetic analysis of Microcystis cf. aeruginosa CV01’s genome revealed its close relationship with other Microcystis genomes, as well as clustering with other continental African strains, suggesting geographical coherency. In addition, it revealed several clusters of known toxin-producing genes. This survey reinforces the need to better understand the country’s microbial ecology as a whole of water reservoirs on the rise.

1987-01-01

In 1973, the design and planning for the Palo Verde Nuclear Generating Station Was started featuring three 3800 MWt Combustion Engineering Standard System 80 Nuclear Steam Supply Systems. Arizona Public Service Company (APS) was the Project Manager and Operating Agent and Bechtel Power Corporation the architect/engineer and constructor. The Palo Verde units are located in a desert environment some 50 miles west of Phoenix, Arizona. It is a 'dry site' in that there are no liquid discharges from the site. The cooling tower makeup water sewage is waste effluent from the City of Phoenix treated at an on site reclamation facility. The effluent has had primary and secondary treatment at the Phoenix plant prior to delivery to PVNGS. The units are physically separate from each other but are of identical design. There are no shared safety systems between the units. Unit 1 and Unit 2 are both in commercial operation (January, 1986 and September, 1986 respectively). Unit 3 is scheduled to load fuel late in the first quarter of 1987. This paper presents some of the engineering and management practices used during design, construction, and startup and operational experiences and other unique features of this multi-unit nuclear station. The site arrangement is shown in Figure 1

2012-10-01

In this work the main results of the simulation of overpressure events are presented using a model of the nuclear power plant of Laguna Verde developed for the RELAP/SCDAPSIM code. As starting point we have the conformation of a Laguna Verde model that represents a stationary state to similar conditions to the operation of the power station with Extended Power Up rate (EPU). The transitory of simulated pressure are compared with those documented in the Final Safety Analysis Report of Laguna Verde (FSAR). The results of the turbine shot transitory with and without by-pass of the main turbine are showed, and the event of closes of all the valves of main vapor isolation. A preliminary simulation was made and with base in the results some adjustments were made for the operation with EPU, taking into account the Operation Technical Specifications of the power station. The results of the final simulations were compared and analyzed with the content in the FSAR. The response of the power station to the transitory, reflected in the model for RELAP, was satisfactory. Finally, comments about the improvement of the model are included, for example, the response time of the protection and mitigation systems of the power station. (Author)

The present work is a continuation of the task: Modeling of the vapor cycle of Laguna Verde with the PEPSE code to conditions of thermal power licensed at present (2027 MWt) in which the modeling of the vapor cycle of the nuclear power plant of Laguna Verde was realized with PEPSE code (Performance Evaluation of Power System Efficiencies). Once reached the conditions of nominal operation of extended power increase, operating both units to 2371 MWt; after the tests phase of starting-up and operation is necessary to carry out a verification of the proposed design of the vapor cycle for the new operation conditions. All this, having in consideration that the vapor cycle designer only knows the detail of the prospective performance of the main turbine, for all the other components (for example pumps, heat inter changers, valves, reactor, humidity separators and re-heaters, condensers, etc.) makes generic suppositions based on engineering judgment. This way carries out the calculations of thermal balance to determine the guaranteed gross power. The purpose of the present work is to comment the detail of the validation carried out of the specific thermal balance (thermal kit) of the nuclear power plant, making use of the design characteristics of the different components that conform the vapor cycle.

Variations in seabed gradient are widely acknowledged to influence deep-water deposition, but are often difficult to measure in sufficient detail from both modern and ancient examples. On the continental slope offshore Los Angeles, California, autonomous underwater vehicle, remotely operated vehicle, and shipboard methods were used to collect a dense grid of high-resolution multibeam bathymetry, chirp sub-bottom profiles, and targeted sediment core samples that demonstrate the influence of seafloor gradient on sediment accumulation, depositional environment, grain size of deposits, and seafloor morphology. In this setting, restraining and releasing bends along the active right-lateral Palos Verdes Fault create and maintain variations in seafloor gradient. Holocene down-slope flows appear to have been generated by slope failure, primarily on the uppermost slope (~ 100–200 m water depth). Turbidity currents created a low relief (water depositional systems. These results help to bridge gaps in scale between existing deep-sea and experimental datasets and may provide constraints for future numerical modeling studies.

Insights gained from the internal events probabilistic risk assessment (PRA) and from the pilot plant demonstration of the fire-induced vulnerability evaluation (FIVE) have been used to initiate corrective actions in the form of administrative controls, compensatory measures, and plant modifications to reduce the risks associated with significant core-damage sequences. Palo Verde was a pilot demonstration plant for the FIVE methodology developed by the Electrical Power Research Institute and sponsored by the Nuclear Utility Management and Resources Council. Several findings emerged from the application of FIVE and have been acted upon to reduce the impact of fire in several compartments of the plant

We report on the initial results from a measurement of the antineutrino flux and spectrum at a distance of about 800 m from the three reactors of the Palo Verde Nuclear Generating Station using a segmented gadolinium-loaded scintillation detector. We find that the antineutrino flux agrees with that predicted in the absence of oscillations excluding at 90% C.L. nu;(e)-nu;(x) oscillations with Deltam(2)>1.12x10(-3) eV(2) for maximal mixing and sin (2)2straight theta>0.21 for large Deltam(2). Our results support the conclusion that the atmospheric neutrino oscillations observed by Super-Kamiokande do not involve nu(e).

Depositional history of organic contaminants on the Palos Verdes Shelf, California

Science.gov (United States)

Eganhouse, R.P.; Pontolillo, J.

2000-01-01

During more than 60 years, sedimentation on the Palos Verdes Shelf has been dominated by time-varying inputs of municipal wastewater from the Los Angeles County Sanitation Districts (LACSD) and debris from the Portuguese Bend Landslide (PBL). The present study examines the depositional history of wastewater-derived organic contaminants at a site approximately 6-8 km downcurrent from the outfall system. Sediments at this location are impacted by contributions from both sources, but the relative influence of the sources has changed over time. Two classes of hydrophobic organic contaminants (chlorinated hydrocarbons, long-chain alkylbenzenes) were determined in sediment cores collected in 1981 and 1992. Using molecular stratigraphy, we determined average sedimentation rates (cm/year) and mass accumulation rates (g cm-2 year-1) for the following periods: 1955-1965, 1965-1971, 1971-1981 and 1981-1992. The results show that sedimentation and mass accumulation rates increased from 1955 to 1971 and decreased from 1971 to 1981. These trends are consistent with historical information on the emission of suspended solids from the outfall system, indicating that the discharge of wastes dominated sedimentation at the site during this period. In the 1980s and early 1990s, however, mass accumulation rates increased in spite of continually decreasing emissions of wastewater solids. Several lines of evidence indicate that this increase was due to mobilization of debris from the PBL during and after unusually strong winter storms in the 1980s. As a result, heavily contaminated sediments deposited during the years of greatest waste emissions (i.e. 1950-1970) have been buried to greater sub-bottom depths, thereby reducing their availability for mobilization to the overlying water column. These results highlight the dynamic nature of sedimentation in contaminated coastal ecosystems and its importance to the long-term fate and effects of toxic substances.

The reason is to give to know to the nuclear community in Mexico the good results that it located in the 2006 to the Laguna Verde Nucleo electric Central in the classification of the World Association of Nuclear Operators (WANO) like one of the best in the worldwide scale, and their Strategic Plan 2007-2011 like an opportunity to continue improving the Quality, the Competitiveness and the Excellency in their Generating Units. It stands out that the fuel reloads are carried out in systemic form in less than 30 days, and also other achievements like it is the certificate granted by PROFEPA of Clean Industry, the renovation of the Certifications of the ISO-9001 and the ISO-14001, as well as the accredit of the Laboratories, and they will give data of the project of the increment of power that their power rose in 15%. For those results in the Strategic Planning 2007-2011 are pointed out that the Laguna Verde Central is a highly viable option in Mexico, when continuing with reloads that will allow a capacity factor up of 90%, and the other concepts that will give the obtaining of the qualification level 1 of WANO in this strategic period. Finally I will conclude with the good news for the Nuclear Industry in Mexico that published the Reforma newspaper at November 01, 2006: 'To the president of Mexico, Felipe Calderon, interests him to impel during his command the alternating energy sources to the hydrocarbons, known it is that the hydrocarbons (petroleum, coal or natural gas) they are finite, while the appetite of the world for the energy is infinite. As you they know, Mexico possesses a nuclear plant that generates energy starting from enriched uranium: the famous Laguna Verde Thermonuclear Central. He declared that Mexico can and it should advance for the one on the way to the energy generation for the nuclear road.' (Author)0.

A classificação foi efetuada independentemente, por três classificadores, com a contagem de grãos "normais" e daqueles considerados defeitos, isto é, "verde" (três categorias, "ardido" e "prêto". Notou-se uma elevada porcentagem de grãos normais quanto à coloração, e também a ocorrência de grãos dos tipos "ardido" e "prêto", no café não maduro. Com a remoção da película prateada verificou-se uma redução na porcentagem de grãos "verdes" e um acentuado aumento na porcentagem de grãos "ardidos", e um aumento menor na de grãos "normais" e "prêtos". Estas observações indicam que os grãos normalmente classificados no comércio como "verdes" devem esta característica à côr .anormal da película, e que os grãos "ardidos" têm, como uma das suas origens, a colheita de frutos verdes.The frequency of defective coffee beans was determined in samples of unripe fruits of the cultivar Mundo Novo (Coffea arabica.Ten samples of 1000 seeds each obtained from green fruits after sundrying and shelling were independently scored for the commercial defects by three coffee classifiers. Each one of the classifiers recorded the occurrence of green-coated, brown and black beans before and after removal of the silver skin. The data revealed that more than half of the beans had normal green color whereas 44.9 per cent were green-coated, 3.5 per cent were brown and 0.1 per cent were black beans. The removal of the silver skin affected the previous classification giving 59.7 per cent of normal green beans, 39.5 per cent of brown and 0.3 per cent of black beans. These observations indicated that the so-called green-coated beans are caused by the presence of the silver skin which retains green pigments probably chlorophyll. On the other hand the browns which have been considered as product of over-fermentation were

The Foraging Ecology of the Endangered Cape Verde Shearwater, a Sentinel Species for Marine Conservation off West Africa.

Vitor H Paiva

Full Text Available Large Marine Ecosystems such as the Canary Current system off West Africa sustains high abundance of small pelagic prey, which attracts marine predators. Seabirds are top predators often used as biodiversity surrogates and sentinel species of the marine ecosystem health, thus frequently informing marine conservation planning. This study presents the first data on the spatial (GPS-loggers and trophic (stable isotope analysis ecology of a tropical seabird-the endangered Cape Verde shearwater Calonectris edwardsii-during both the incubation and the chick-rearing periods of two consecutive years. This information was related with marine environmental predictors (species distribution models, existent areas of conservation concern for seabirds (i.e. marine Important Bird Areas; marine IBAs and threats to the marine environment in the West African areas heavily used by the shearwaters. There was an apparent inter-annual consistency on the spatial, foraging and trophic ecology of Cape Verde shearwater, but a strong alteration on the foraging strategies of adult breeders among breeding phases (i.e. from incubation to chick-rearing. During incubation, birds mostly targeted a discrete region off West Africa, known by its enhanced productivity profile and thus also highly exploited by international industrial fishery fleets. When chick-rearing, adults exploited the comparatively less productive tropical environment within the islands of Cape Verde, at relatively close distance from their breeding colony. The species enlarged its trophic niche and increased the trophic level of their prey from incubation to chick-rearing, likely to provision their chicks with a more diversified and better quality diet. There was a high overlap between the Cape Verde shearwaters foraging areas with those of European shearwater species that overwinter in this area and known areas of megafauna bycatch off West Africa, but very little overlap with existing Marine Important Bird

Developing and modeling of the 'Laguna Verde' BWR CRDA benchmark

International Nuclear Information System (INIS)

Solis-Rodarte, J.; Fu, H.; Ivanov, K.N.; Matsui, Y.; Hotta, A.

2002-01-01

Reactivity initiated accidents (RIA) and design basis transients are one of the most important aspects related to nuclear power reactor safety. These events are re-evaluated whenever core alterations (modifications) are made as part of the nuclear safety analysis performed to a new design. These modifications usually include, but are not limited to, power upgrades, longer cycles, new fuel assembly and control rod designs, etc. The results obtained are compared with pre-established bounding analysis values to see if the new core design fulfills the requirements of safety constraints imposed on the design. The control rod drop accident (CRDA) is the design basis transient for the reactivity events of BWR technology. The CRDA is a very localized event depending on the control rod insertion position and the fuel assemblies surrounding the control rod falling from the core. A numerical benchmark was developed based on the CRDA RIA design basis accident to further asses the performance of coupled 3D neutron kinetics/thermal-hydraulics codes. The CRDA in a BWR is a mostly neutronic driven event. This benchmark is based on a real operating nuclear power plant - unit 1 of the Laguna Verde (LV1) nuclear power plant (NPP). The definition of the benchmark is presented briefly together with the benchmark specifications. Some of the cross-sections were modified in order to make the maximum control rod worth greater than one dollar. The transient is initiated at steady-state by dropping the control rod with maximum worth at full speed. The 'Laguna Verde' (LV1) BWR CRDA transient benchmark is calculated using two coupled codes: TRAC-BF1/NEM and TRAC-BF1/ENTREE. Neutron kinetics and thermal hydraulics models were developed for both codes. Comparison of the obtained results is presented along with some discussion of the sensitivity of results to some modeling assumptions

Ocampo, M.H.; DeAlbornoz, B.A.

1988-01-01

A model for the Radiation Monitoring System of the Laguna Verde Boiling Water Reactor training simulator is presented. This model comprises enough definitions to assure interactions with the processes related, directly or indirectly, with the transport of radioisotopes. It is capable of following a dynamic behavior of the plant so an operator could be trained to become aware of nuclear radiation hazards. The model is composed of three parts: the electronics for the Process and Area Radiation Monitoring System; a lumped parameter transport model for the most representative radioisotopes; and the interactions with the modeled processes as well as with process not being simulated. The first part represents the radiation monitor controls in the vertical board panels of the nuclear station. The second part allows the carrying of nuclear isotopes between processes. The third part defines the way that the process interacts with the electronics at the point of release to environment or the point of detection. Each part of the model has been tested individually, and the transport model has been incorporated as a part of each process required to simulate nuclear radiation. The model parameters has been calculated using typical BWR nuclear radiation data, and Laguna Verde heat balance data at 100% design power. However, tunning will be necessary once the Simulator is integrated and tested. The tunning allows each detecting channel to behave as expected

Depois é necessário estabelecer, em conformidade, os principais objetivos a atingir a partir dos desígnios das políticas públicas consensualizadas, ou seja, quais são os valores de largo espectro a atingir, neste caso a sustentabilidade dos sistemas produtivos, a adequação ambiental e paisagística, a que acresce a criação de valor. São também observadas as condicionantes, até porque o complexo agroflorestal é talvez aquele que, no domínio dos sistemas produtivos de criação de valor, está mais condicionado por decisões que são estranhas à nossa soberania, quer se trate da administração central ou local, quanto mais não fosse porque as políticas de incentivos e preços são essencialmente determinadas pela PAC.

The Pedra Verde Copper Mine is located in the Viçosa do Ceará municipality, State of Ceará, NE Brazil. The copper mineralization is hosted by the Pedra Verde Phyllite, which is a carbonaceous chlorite-calcite phyllite with subordinate biotite. It belongs to the Neoproterozoic Martinópole Group of the Médio Coreaú Domain, Borborema Province. The Pedra Verde deposit is stratabound and its ore zoning is conspicuous, according to the following sequence, from bottom to top: marcasite/pyrite, native silver, chalcopyrite, bornite, chalcocite, native copper and hematite. Barite and carbonaceous material are reported in ore zones. Zoning reflects the ore formation within a redox boundary developed due to the interaction between oxidized copper- and sulfate-bearing fluids and the reduced phyllite. Structural control on mineralization is evidenced by the association of the ore minerals with veins, hinge folds, shadow pressures, and mylonitic foliation. It was mainly exercised by a dextral transcurrent shear zone developed during the third deformational stage identified in the Médio Coreaú Domain between 590 Ma and 570 Ma. This points to the importance of epigenetic, post-metamorphic deformational events for ore formation. Oxygen isotopic composition (δ18OH2O = 8.94 to 11.28‰, at 250 to 300 °C) estimated for the hydrothermal fluids in equilibrium with calcite indicates metamorphic or evolved meteoric isotopic signatures. The δ13CPDB values (-2.60 to -9.25‰) obtained for hydrothermal calcite indicate mixing of carbon sources derived from marine carbonate rocks and carbonaceous material. The δ34SCDT values (14.88 to 36.91‰) of sulfides suggest evaporites as sulfate sources or a closed system in relation to SO42- availability to form H2S. Carbonaceous matter had a key role in thermochemical sulfate processes and sulfide precipitation. The Pedra Verde Copper Mine is considered the first stratabound meta-sedimentary rock-hosted copper deposit described in Brazil

La imaginación en un burdel, un sueño latinoamericano hecho ficción: los prostíbulos novelescos (Estudios)

OpenAIRE

Terrones, Félix

2013-01-01

En el año 2009, el escritor Jorge Volpi publicó el ensayo El insomnio de Bolívar en el que argumenta a favor de abandonar, por irreal y quimérica, la idea de “literatura latinoamericana”. Mediante la lectura de cuatro novelas –Juntacadáveres (1964), El lugar sin límites (1965), La casa verde (1966) y Pantaleón y las visitadoras (1973)– buscaré develar lo erróneo y tendencioso de tal postura. Así, fundamentaré mi argumento en el análisis minucioso de los prostíbulos novelescos que albergan las...

Full Text Available O presente trabalho teve como objetivo investigar os efeitos da utilização do chá verde para saúde humana, levantou os benefícios e malefícios, determinou a relação entre o consumo de chá verde e a prevenção de algumas doenças e o emagrecimento. A metodologia adotada foi uma revisão de literatura, dos últimos dez anos, em livros e artigos de diversos autores que abordam o tema chá verde. Cerca de três mil produtos levam o nome de chá, mas na verdade, podem ser considerados como chás somente aqueles que tenham em sua composição a planta Camellia sinensis, que dá origem ao chá verde. Hoje o chá verde, uma das bebidas estimulantes mais consumidas no mundo, é considerado um alimento funcional, que consumido na alimentação cotidiana pode trazer benefícios fisiológicos à saúde, graças aos seus componentes ativos, como os antioxidantes, flavonóides, catequinas, que atuam na prevenção de doenças e em mecanismos específicos do emagrecimento e manutenção do peso corporal. No entanto sua utilização tem sido bastante questionada, motivando a realização de vários estudos para determinar o verdadeiro efeito do chá no organismo e a dose ideal a ser consumida, para que não acarrete prejuízos à saúde, pois ainda não há comprovação científica sobre os benefícios e malefícios que este alimento possa causar em seus usuários. Os hábitos alimentares vão contribuir para o aparecimento ou não de doenças crônicas, com isso a dieta exerce um papel fundamental na prevenção de doenças e para manutenção do peso, aliado a isso à prática de exercícios físicos, obtendo assim um estilo de vida saudável.

Sixty Mesa Verde variety Black-on-white bowls from Castle Rock Pueblo (5MT 1825) and Sand Canyon Pueblo (5MT765) in southwestern Colorado were chemically characterized using neutron activation analysis. Eleven clay sources local to the sites in the McElmo Drainage area were also analyzed. The results revealed two distinct compositional groups containing relative frequencies that imply local production. The occurrence of trade between the two sites was also identified.

Hacia una literatura de disidencia sexual en México con dos Bildungsromane bisexuales: Púrpura, de Ana García Bergua, y Fruta verde, de Enrique Serna

Full Text Available En este artículo propongo una lectura de las novelas mexicanas Púrpura, de Ana García Bergua, y Fruta verde, de Enrique Serna, como representaciones de la bisexualidad que se insertan en, y a la vez rompen con, una tradición literaria que retrata la homosexualidad masculina. Leo el empleo de la ironía y el performance de género en los textos como señalamiento de las contradicciones y dificultades sociales que conllevan la orientación bisexual. El diálogo de las obras con la tradición de la novela de formación problematiza la expresión de sexualidades no normativas y plantea una crítica de las identidades sexuales basadas en el binarismo hetero / homosexual. Sostengo que estas obras deben ser incluidas en y analizadas dentro de la tradición literaria mexicana que retrata sexualidades disidentes, entre las cuales la bisexualidad ha sido una identidad marginada. In this article I propose a reading of the Mexican novels Púrpura by Ana García Bergua and Fruta verde by Enrique Serna as portrayals of bisexuality that both form a part of and break with a literary tradition that portrays male homosexuality. I read the use of irony and gender performance in these texts as a signaling of the social contradictions and problems that come with the bisexual orientation. The dialogue of these works with the tradition of the novel of formation problematizes the expression of non-normative sexualities and critiques sexual identities based on the heter/homo binary. I argue that these works should be included in a Mexican literary tradition that represents dissident sexualities, among which bisexuality has been marginalized and underrepresented.

Benson, L.V.

2011-01-01

Chemical and nutrient analyses of 471 soil samples from 161 sites within four archaeological regions (Pajarito Plateau/Bandelier, Zuni, Mesa Verde, and the Chaco Halo) were combined with historical climate data in order to evaluate the agricultural productivity of each region. In addition, maize productivity and field-life calculations were performed using organic-nitrogen (N) values from the upper 50 cm of soil in each region and a range (1-3%/year) of N-mineralization rates. The endmember values of this range were assumed representative of dry and wet climate states. With respect to precipitation and heat, the Pajarito Plateau area has excellent agricultural potential; the agricultural potentials of the Zuni and Mesa Verde regions are good; and the agricultural potential of the Chaco Halo is poor. Calculations of N mineralization and field life indicate that Morfield Valley in Mesa Verde should be able to provide 10 bu/ac of maize for decades (without the addition of N) when organic N-mineralization rates exceed 2%. Productivity and field-life potential decrease in the following order: Zuni, Mesa Verde, Bandelier, Chaco Halo. The Chaco Halo is very unproductive; e. g., 10 bushels per acre can be achieved within the Halo only from soils having the highest organic N concentration (third quartile) and which undergo the highest rate (3%) of N mineralization. ?? 2010 US Government.
